A pragmatic randomized controlled trial of computerized CBT (SPARX) for symptoms of depression among adolescents excluded from mainstream education.
Background: Adolescents excluded from mainstream education have high mental health needs. The use of computerized Cognitive Behavioural Therapy (cCBT) has not been investigated with this group.
Aims: To test the efficacy of the SPARX cCBT programme for symptoms of depression among adolescents in programmes for students excluded or alienated from mainstream education.
Method: Adolescents (32; 34% Maori, 38% Pacific Island, 56% male) aged 13-16 with Child Depression Rating Scale Revised (CDRS-R) scores indicating possible through to almost certain depressive disorder were randomized to SPARX to be completed over the following 5 weeks (n = 20) or to waitlist control (n = 12). Assessments were at baseline, 5 weeks and 10 weeks. Those in the wait condition were invited to complete SPARX after the 5 week assessment.
Results: Most participants (n = 26, 81%) completed at least 4 levels of SPARX and 22 (69%) completed all 7 levels. Among the 30 (94%) participants who began treatment as randomized and provided 5-week data, significant differences were found between cCBT and wait groups on the CDRS-R (baseline to 5-week mean change -14.7 versus -1.1, p<.001), remission (78% vs. 36%, p = .047) and on the Reynolds Adolescent Depression Scale (-4.6 vs. +3.2 p = .05) but not on other self-rating psychological functioning scales. In intent-to-treat analyses CDRS-R changes and remission remained significant. Gains were maintained at 10-week follow-up.
Conclusions: SPARX appears to be a promising treatment for students with symptoms of depression who are in alternative schooling programmes for those excluded from mainstream education.

Efficacy of digital cognitive behavioural therapy for insomnia: a meta-analysis of randomised controlled trials.
Objectives: Although cognitive behavioural therapy for insomnia (CBT-I) has been recommended the initial therapy for insomnia, its clinical usage remains limited due to the lack of therapists. Digital CBT-I (dCBT-I) can potentially circumvent this problem. This meta-analysis aims to evaluate the short-term and long-term efficacy of dCBT-I for adults with insomnia.
Methods: Systematic search of PubMed, EMBASE, PsycINFO, and CENTRAL from inception till 5 March 2020 was conducted. Randomised controlled trials (RCTs) comparing dCBT-I with controls (wait-list/treatment-as-usual/online education) in adults with insomnia were eligible. The primary outcome was insomnia severity index (ISI) at post-intervention, short-term follow-up (ranging 4 weeks to 6 months) and 1-year follow-up. Mean differences were pooled using the random-effects model.
Results: 94 articles were assessed full-text independently by two team members and 33 studies were included in this meta-analysis. 4719 and 4645 participants were randomised to dCBT-I and control respectively. dCBT-I significantly reduces ISI at post-intervention with mean difference -5.00 (95% CI -5.68 to -4.33, p < 0.0001) (I2 = 79%) compared to control. The improvements were sustained at short-term follow-up, -3.99 (95% CI -4.82 to -3.16, p < 0.0001) and 1-year follow-up, -3.48 (95% CI -4.21 to -2.76, p < 0.0001). Compared to dCBT-I, face-to-face CBT-I produced greater improvement in ISI, 3.07 (95% CI 1.18 to 4.95, p = 0.001). However, this was within the non-inferiority interval of 4 points on ISI.
Conclusion: This meta-analysis provides strong support for the effectiveness of dCBT-I in treating insomnia. dCBT-I has potential to revolutionise the delivery of CBT-I, improving the accessibility and availability of CBT-I content for insomnia patients worldwide.

Psychiatric and neuropsychiatric presentations associated with severe coronavirus infections: a systematic review and meta-analysis with comparison to the COVID-19 pandemic.
Background: Before the COVID-19 pandemic, coronaviruses caused two noteworthy outbreaks: severe acute respiratory syndrome (SARS), starting in 2002, and Middle East respiratory syndrome (MERS), starting in 2012. We aimed to assess the psychiatric and neuropsychiatric presentations of SARS, MERS, and COVID-19.
Methods: In this systematic review and meta-analysis, MEDLINE, Embase, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature databases (from their inception until March 18, 2020), and medRxiv, bioRxiv, and PsyArXiv (between Jan 1, 2020, and April 10, 2020) were searched by two independent researchers for all English-language studies or preprints reporting data on the psychiatric and neuropsychiatric presentations of individuals with suspected or laboratory-confirmed coronavirus infection (SARS coronavirus, MERS coronavirus, or SARS coronavirus 2). We excluded studies limited to neurological complications without specified neuropsychiatric presentations and those investigating the indirect effects of coronavirus infections on the mental health of people who are not infected, such as those mediated through physical distancing measures such as self-isolation or quarantine. Outcomes were psychiatric signs or symptoms; symptom severity; diagnoses based on ICD-10, DSM-IV, or the Chinese Classification of Mental Disorders (third edition) or psychometric scales; quality of life; and employment. Both the systematic review and the meta-analysis stratified outcomes across illness stages (acute vs post-illness) for SARS and MERS. We used a random-effects model for the meta-analysis, and the meta-analytical effect size was prevalence for relevant outcomes, I2 statistics, and assessment of study quality.
Findings: 1963 studies and 87 preprints were identified by the systematic search, of which 65 peer-reviewed studies and seven preprints met inclusion criteria. The number of coronavirus cases of the included studies was 3559, ranging from 1 to 997, and the mean age of participants in studies ranged from 12·2 years (SD 4·1) to 68·0 years (single case report). Studies were from China, Hong Kong, South Korea, Canada, Saudi Arabia, France, Japan, Singapore, the UK, and the USA. Follow-up time for the post-illness studies varied between 60 days and 12 years. The systematic review revealed that during the acute illness, common symptoms among patients admitted to hospital for SARS or MERS included confusion (36 [27·9%; 95% CI 20·5-36·0] of 129 patients), depressed mood (42 [32·6%; 24·7-40·9] of 129), anxiety (46 [35·7%; 27·6-44·2] of 129), impaired memory (44 [34·1%; 26·2-42·5] of 129), and insomnia (54 [41·9%; 22·5-50·5] of 129). Steroid-induced mania and psychosis were reported in 13 (0·7%) of 1744 patients with SARS in the acute stage in one study. In the post-illness stage, depressed mood (35 [10·5%; 95% CI 7·5-14·1] of 332 patients), insomnia (34 [12·1%; 8·6-16·3] of 280), anxiety (21 [12·3%; 7·7-17·7] of 171), irritability (28 [12·8%; 8·7-17·6] of 218), memory impairment (44 [18·9%; 14·1-24·2] of 233), fatigue (61 [19·3%; 15·1-23·9] of 316), and in one study traumatic memories (55 [30·4%; 23·9-37·3] of 181) and sleep disorder (14 [100·0%; 88·0-100·0] of 14) were frequently reported. The meta-analysis indicated that in the post-illness stage the point prevalence of post-traumatic stress disorder was 32·2% (95% CI 23·7-42·0; 121 of 402 cases from four studies), that of depression was 14·9% (12·1-18·2; 77 of 517 cases from five studies), and that of anxiety disorders was 14·8% (11·1-19·4; 42 of 284 cases from three studies). 446 (76·9%; 95% CI 68·1-84·6) of 580 patients from six studies had returned to work at a mean follow-up time of 35·3 months (SD 40·1). When data for patients with COVID-19 were examined (including preprint data), there was evidence for delirium (confusion in 26 [65%] of 40 intensive care unit patients and agitation in 40 [69%] of 58 intensive care unit patients in one study, and altered consciousness in 17 [21%] of 82 patients who subsequently died in another study). At discharge, 15 (33%) of 45 patients with COVID-19 who were assessed had a dysexecutive syndrome in one study. At the time of writing, there were two reports of hypoxic encephalopathy and one report of encephalitis. 68 (94%) of the 72 studies were of either low or medium quality.
Interpretation: If infection with SARS-CoV-2 follows a similar course to that with SARS-CoV or MERS-CoV, most patients should recover without experiencing mental illness. SARS-CoV-2 might cause delirium in a significant proportion of patients in the acute stage. Clinicians should be aware of the possibility of depression, anxiety, fatigue, post-traumatic stress disorder, and rarer neuropsychiatric syndromes in the longer term.

Gowers SG, Clark AF, Roberts C, Byford S, Barrett B, Griffiths A, Edwards V, Bryan C, Smethurst N, Rowlands L, Roots P. (2010)MEDLINE-indexed journal, not yet read by usHealth technology assessment (Winchester, England) · randomised controlled trial A randomised controlled multicentre trial of treatments for adolescent anorexia nervosa including assessment of cost-effectiveness and patient acceptability - the TOuCAN trial.
Objective: To evaluate the clinical effectiveness and cost-effectiveness of inpatient compared with outpatient treatment and general (routine) treatment in Child and Adolescent Mental Health Services (CAMHS) against specialist treatment for young people with anorexia nervosa. In addition, to determine young people's and their carers' satisfaction with these treatments.
Design: A population-based, pragmatic randomised controlled trial (RCT) was carried out on young people age 12 to 18 presenting to community CAMHS with anorexia nervosa.
Setting: Thirty-five English CAMHS in the north-west of England co-ordinated through specialist centres in Manchester and Liverpool.
Participants: Two hundred and fifteen young people (199 female) were identified, of whom 167 (mean age 14 years 11 months) were randomised and 48 were followed up as a preference group.
Interventions: Randomised patients were allocated to either inpatient treatment in one of four units with considerable experience in the treatment of anorexia nervosa, a specialist outpatient programme delivered in one of two centres, or treatment as usual in general community CAMHS. The outpatient programmes spanned 6 months of treatment. The length of inpatient treatment was determined on a case-by-case basis on clinical need with outpatient follow-up to a minimum of 6 months.
Main outcome measures: Follow-up assessments were carried out at 1, 2 and 5 years. The primary outcome measure was the Morgan-Russell Average Outcome Scale (MRAOS) and associated categorical outcomes. Secondary outcome measures included physical measures of weight, height, body mass index (BMI) and % weight for height. Research ratings included the Health of the National Outcome Scale for Children and Adolescents (HoNOSCA). Self report measures comprised the user version of HoNOSCA (HoNOSCA-SR), the Eating Disorder Inventory 2 (EDI-2), the Family Assessment Device (FAD) and the recent Mood and Feelings Questionnaire (MFQ). Information on resource use was collected in interview at 1, 2 and 5 years using the Child and Adolescent Service Use Schedule (CA-SUS). Satisfaction was measured quantitatively using a questionnaire designed for the study and qualitative (free) responses on it. The questionnaire data were supplemented by qualitative analysis of user and carer focus groups.
Results: Of the 167 patients randomised, 65% adhered to the allocated treatment. Adherence was lower for inpatient treatment (49%) than for general CAMHS (71%) or specialist outpatient treatment (77%) (p = 0.013). Every subject was traced at both 1 and 2 years, with the main outcome measure completed (through contact with the subject, family members or clinicians), by 94% at 1 year, 93% at 2 years, but only 47% at 5 years. A validated outcome category was assigned for 98% at 1 year, 96% at 2 years and 60% at 5 years. There was significant improvement in all groups at each time point, with the number achieving a good outcome being 19% at 1 year, 33% at 2 years and 64% (of those followed up) at 5 years. Analysis demonstrated no difference in treatment effectiveness of randomisation to inpatient compared with outpatient treatment, or, specialist over generalist treatment at any time point, when baseline characteristics were taken into account. Generalist CAMHS treatment was slightly more expensive over the first 2 years of the study, largely because greater numbers were subsequently admitted to hospital after the initial treatment phase. The specialist outpatient programme was the dominant treatment in terms of incremental cost-effectiveness. Specialist treatments had a higher probability of being more cost-effective than generalist treatments and outpatient treatment had a higher probability of being more cost-effective than inpatient care. Parental satisfaction with treatment was generally good, though better with specialist than generalist treatment. Young people's satisfaction was much more mixed, but again better with specialist treatment, including inpatient care.
Conclusion: Poor adherence to randomisation (despite initial consent to it), limits the assessment of the treatment effect of inpatient care. However, this study provides little support for lengthy inpatient psychiatric treatment on clinical or health economic grounds. These findings are broadly consistent with existing guidelines on the treatment of anorexia nervosa, which suggest that outpatient treatments should be offered to the majority, with inpatient treatment offered in rare cases, though our findings lend little support to a stepped-care approach in which inpatient care is offered to outpatient non-responders. Outpatient care, supported by brief (medical) inpatient management for correction of acute complications may be a preferable approach. The health economic analysis and user views both support NICE guidelines, which suggest that anorexia nervosa should be managed in specialist services that have experience and expertise in its management. Comprehensive general CAMHS might, however, be well placed to manage milder cases. Further research should focus on the specific components of outpatient psychological therapies. Although family-based treatments are well established, trials have not established their effectiveness compared with good-quality individual psychological therapies and the combination of individual and family approaches is untested. Further research is needed to establish which patients (if any) might respond to inpatient psychiatric treatment when unresponsive to outpatient care, the positive and negative components of it and the optimum length of stay.

Resilience, self-esteem and self-compassion in adults with spina bifida.
Study design: Cross-sectional survey.
Objectives: To examine factors that may enhance and promote resilience in adults with spina bifida.
Setting: Community-based disability organisations within Australia.
Methods: Ninety-seven adults with a diagnosis of spina bifida (SB) completed a survey comprising of demographic questions in addition to standardised self-report measures of physical functioning (Craig Handicap Assessment and Reporting Technique), resilience (Connor-Davidson Resilience Scale, 10 item), self-esteem (Rosenberg Self-esteem Scale), self-compassion (Self-compassion Scale) and psychological distress (Depression Anxiety Stress Scales, 21 item).
Results: The majority (66%) of respondents reported moderate to high resilience. Physical disability impacted on coping, with greater CD-RISC 10 scores reported by individuals who were functionally independent in addition to those who experienced less medical co-morbidities. Significant correlations between resilience and psychological traits (self-esteem r=0.36, P<0.01; self-compassion r=0.40, P<0.01) were also noted. However, the combined contribution of these variables only accounted for 23% of the total variance in resilience scores (R(2)=0.227, F(5,94)=5.23, P<0.01).
Conclusion: These findings extend current understanding of the concept of resilience in adults with a congenital physical disability. The suggestion is that resilience involves a complex interplay between physical determinants of health and psychological characteristics, such as self-esteem and self-compassion. It follows that cognitive behavioural strategies with a focus on self-management may, in part, contribute to the process of resilience in this group. Further large-scale and longitudinal research will help to confirm these findings.

Efficacy of Gabapentin for the Treatment of Alcohol Use Disorder in Patients With Alcohol Withdrawal Symptoms: A Randomized Clinical Trial.
Importance: Although an estimated 30 million people meet criteria for alcohol use disorder (AUD), few receive appropriate pharmacotherapy. A more personalized, symptom-specific, approach might improve efficacy and acceptance.
Objective: To examine whether gabapentin would be useful in the treatment of AUD, especially in those with the most alcohol withdrawal symptoms.
Design, setting, and participants: This double-blind randomized clinical trial conducted between November 2014 and June 2018 evaluated gabapentin vs placebo in community-recruited participants screened and treated in an academic outpatient setting over a 16-week treatment period. A total of 145 treatment-seeking individuals who met Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for AUD and were not receiving other AUD intervention were screened, and 96 who also met recent alcohol withdrawal criteria were randomized to treatment after 3 abstinent days. Daily drinking was recorded, and percentage of disialo carbohydrate-deficient transferrin in the blood, a heavy drinking marker, was collected at baseline and monthly during treatment.
Interventions: Gabapentin up to 1200 mg/d, orally, vs placebo along with 9 medical management visits (20 minutes each).
Main outcomes and measures: The percentage of individuals with no heavy drinking days and those with total abstinence were compared between treatment groups and further evaluated based on prestudy alcohol withdrawal symptoms.
Results: Of 96 randomized individuals, 90 were evaluable (44 in the gabapentin arm and 46 in the placebo arm), with a mean (SD) age of 49.6 (10.1) years; 69 were men (77%) and 85 were white (94%). The evaluable participants had 83% baseline heavy drinking days (4 or more drinks/day for women, 5 or more for men) and met 4.5 alcohol withdrawal criteria from the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). More gabapentin-treated individuals had no heavy drinking days (12 of 44 participants [27%]) compared with placebo (4 of 46 participants [9%]), a difference of 18.6% (95% CI, 3.1-34.1; P = .02; number needed to treat [NNT], 5.4), and more total abstinence (8 of 44 [18%]) compared with placebo (2 of 46 [4%]), a difference of 13.8% (95% CI, 1.0-26.7; P = .04; NNT, 6.2). The prestudy high-alcohol withdrawal group had positive gabapentin effects on no heavy drinking days (P < .02; NNT, 3.1) and total abstinence (P = .003; NNT, 2.7) compared with placebo, while within the low-alcohol withdrawal group, there were no significant differences. These findings were similar for other drinking variables, where gabapentin was more efficacious than placebo in the high-alcohol withdrawal group only. Gabapentin caused more dizziness, but this did not affect efficacy.
Conclusions and relevance: These data, combined with others, suggest gabapentin might be most efficacious in people with AUD and a history of alcohol withdrawal symptoms. Future studies should evaluate sleep changes and mood during early recovery as mediators of gabapentin efficacy.

The Use of Online Posts to Identify Barriers to and Facilitators of HIV Pre-exposure Prophylaxis (PrEP) Among Men Who Have Sex with Men: A Comparison to a Systematic Review of the Peer-Reviewed Literature.
Pre-exposure prophylaxis (PrEP) remains an under-utilized HIV prevention tool among men who have sex with men (MSM). To more comprehensively elucidate barriers and facilitators to PrEP use among US MSM, we conducted a systematic review of peer-reviewed published articles and content analysis of online posts about PrEP. We searched peer-reviewed databases (Medline, Web of Science, Google Scholar) using MESH headings and keywords about PrEP and/or HIV prevention from 2005 to 2015. We included original studies among MSM in the US that reported on barriers, facilitators, or other factors related to PrEP use. We also searched online posts and associated comments (news articles, opinion pieces, blogs and other social media posts) in diverse venues (Facebook, Slate Outward, Huffington Post Gay Voices, Queerty, and My PrEP Experience blog) to identify posts about PrEP. We used content analysis to identify themes and compare potential differences between the peer-reviewed literature and online posts. We identified 25 peer-reviewed articles and 28 online posts meeting inclusion criteria. We identified 48 unique barriers and 46 facilitators to using PrEP. These 94 themes fit into six overarching categories: (1) access (n = 14), (2) attitudes/beliefs (n = 24), (3) attributes of PrEP (n = 13), (4) behaviors (n = 11), (5) sociodemographic characteristics (n = 8), and (6) social network (n = 6). In all categories, analysis of online posts resulted in identification of a greater number of unique themes. Thirty-eight themes were identified in the online posts that were not identified in the peer-reviewed literature. We identified barriers and facilitators to PrEP in online posts that were not identified in a systematic review of the peer-reviewed literature. By incorporating data both from a systematic review of peer-reviewed articles and from online posts, we have identified salient and novel information about barriers to and facilitators of PrEP use. Traditional research approaches may not comprehensively capture current factors important for designing and implementing PrEP related interventions.

Peer Support for the Hardly Reached: A Systematic Review.
Background: Health disparities are aggravated when prevention and care initiatives fail to reach those they are intended to help. Groups can be classified as hardly reached according to a variety of circumstances that fall into 3 domains: individual (e.g., psychological factors), demographic (e.g., socioeconomic status), and cultural-environmental (e.g., social network). Several reports have indicated that peer support is an effective means of reaching hardly reached individuals. However, no review has explored peer support effectiveness in relation to the circumstances associated with being hardly reached or across diverse health problems.
Objectives: To conduct a systematic review assessing the reach and effectiveness of peer support among hardly reached individuals, as well as peer support strategies used.
Search methods: Three systematic searches conducted in PubMed identified studies that evaluated peer support programs among hardly reached individuals. In aggregate, the searches covered articles published from 2000 to 2015.
Selection criteria: Eligible interventions provided ongoing support for complex health behaviors, including prioritization of hardly reached populations, assistance in applying behavior change plans, and social-emotional support directed toward disease management or quality of life. Studies were excluded if they addressed temporally isolated behaviors, were limited to protocol group classes, included peer support as the dependent variable, did not include statistical tests of significance, or incorporated comparison conditions that provided appreciable social support.
Data collection and analysis: We abstracted data regarding the primary health topic, categorizations of hardly reached groups, program reach, outcomes, and strategies employed. We conducted a 2-sample t test to determine whether reported strategies were related to reach.
Results: Forty-seven studies met our inclusion criteria, and these studies represented each of the 3 domains of circumstances assessed (individual, demographic, and cultural-environmental). Interventions addressed 8 health areas, most commonly maternal and child health (25.5%), diabetes (17.0%), and other chronic diseases (14.9%). Thirty-six studies (76.6%) assessed program reach, which ranged from 24% to 79% of the study population. Forty-four studies (94%) reported significant changes favoring peer support. Eleven strategies emerged for engaging and retaining hardly reached individuals. Among them, programs that reported a strategy of trust and respect had higher participant retention (82.8%) than did programs not reporting such a strategy (48.1%; P = .003). In 5 of the 6 studies examining moderators of the effects of peer support, peer support benefits were greater among individuals characterized by disadvantage (e.g., low health literacy).
Conclusions: Peer support is a broad and robust strategy for reaching groups that health services too often fail to engage. The wide range of audiences and health concerns among which peer support is successful suggests that a basis for its success may be its flexible response to different contexts, including the intended audience, health problems, and setting.
Public health implications: The general benefits of peer support and findings suggesting that it may be more effective among those at heightened disadvantage indicate that peer support should be considered in programs intended to reach and benefit those too often hardly reached. Because engendering trust and respect was significantly associated with participant retention, programs should emphasize this strategy.

Intelligent Physical Robots in Health Care: Systematic Literature Review.
Background: Intelligent physical robots based on artificial intelligence have been argued to bring about dramatic changes in health care services. Previous research has examined the use of intelligent physical robots in the health care context from different perspectives; however, an overview of the antecedents and consequences of intelligent physical robot use in health care is lacking in the literature.
Objective: In this paper, we aimed to provide an overview of the antecedents and consequences of intelligent physical robot use in health care and to propose potential agendas for future research through a systematic literature review.
Methods: We conducted a systematic literature review on intelligent physical robots in the health care field following the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Literature searches were conducted in 5 databases (PubMed, Scopus, PsycINFO, Embase, and CINAHL) in May 2021, focusing on studies using intelligent physical robots for health care purposes. Subsequently, the quality of the included studies was assessed using the Mixed Methods Appraisal Tool. We performed an exploratory content analysis and synthesized the findings extracted from the included articles.
Results: A total of 94 research articles were included in the review. Intelligent physical robots, including mechanoid, humanoid, android, and animalistic robots, have been used in hospitals, nursing homes, mental health care centers, laboratories, and patients' homes by both end customers and health care professionals. The antecedents for intelligent physical robot use are categorized into individual-, organization-, and robot-related factors. Intelligent physical robot use in the health care context leads to both non-health-related consequences (emotional outcomes, attitude and evaluation outcomes, and behavioral outcomes) and consequences for (physical, mental, and social) health promotion for individual users. Accordingly, an integrative framework was proposed to obtain an overview of the antecedents and consequences of intelligent physical robot use in the health care context.
Conclusions: This study contributes to the literature by summarizing current knowledge in the field of intelligent physical robot use in health care, by identifying the antecedents and the consequences of intelligent physical robot use, and by proposing potential future research agendas in the specific area based on the research findings in the literature and the identified knowledge gaps.

Edwards EA, Lumsden J, Rivas C, Steed L, Edwards LA, Thiyagarajan A, Sohanpal R, Caton H, Griffiths CJ, Munafò MR, Taylor S, Walton RT. (2016)MEDLINE-indexed journal, not yet read by usBMJ open · systematic review Gamification for health promotion: systematic review of behaviour change techniques in smartphone apps.
Objective: Smartphone games that aim to alter health behaviours are common, but there is uncertainty about how to achieve this. We systematically reviewed health apps containing gaming elements analysing their embedded behaviour change techniques.
Methods: Two trained researchers independently coded apps for behaviour change techniques using a standard taxonomy. We explored associations with user ratings and price.
Data sources: We screened the National Health Service (NHS) Health Apps Library and all top-rated medical, health and wellness and health and fitness apps (defined by Apple and Google Play stores based on revenue and downloads). We included free and paid English language apps using 'gamification' (rewards, prizes, avatars, badges, leaderboards, competitions, levelling-up or health-related challenges). We excluded apps targeting health professionals.
Results: 64 of 1680 (4%) health apps included gamification and met inclusion criteria; only 3 of these were in the NHS Library. Behaviour change categories used were: feedback and monitoring (n=60, 94% of apps), reward and threat (n=52, 81%), and goals and planning (n=52, 81%). Individual techniques were: self-monitoring of behaviour (n=55, 86%), non-specific reward (n=49, 82%), social support unspecified (n=48, 75%), non-specific incentive (n=49, 82%) and focus on past success (n=47, 73%). Median number of techniques per app was 14 (range: 5-22). Common combinations were: goal setting, self-monitoring, non-specific reward and non-specific incentive (n=35, 55%); goal setting, self-monitoring and focus on past success (n=33, 52%). There was no correlation between number of techniques and user ratings (p=0.07; rs=0.23) or price (p=0.45; rs=0.10).
Conclusions: Few health apps currently employ gamification and there is a wide variation in the use of behaviour change techniques, which may limit potential to improve health outcomes. We found no correlation between user rating (a possible proxy for health benefits) and game content or price. Further research is required to evaluate effective behaviour change techniques and to assess clinical outcomes.

Fathers' Representation in Observational Studies on Parenting and Childhood Obesity: A Systematic Review and Content Analysis.
Background: The involvement of fathers in caregiving has increased substantially over the past 30 years. Yet in child and adolescent psychopathology, few studies include fathers as research participants and few present results for fathers separate from those for mothers. We test for the first time whether a similar pattern exists in research on parenting and childhood obesity.
Objectives: To conduct a systematic review and quantitative content analysis of observational studies on parenting and childhood obesity to (1) document the inclusion of fathers, relative to mothers, as research participants and (2) examine characteristics of studies that did and did not include fathers. This study presents new data on the number and gender of parent research participants.
Search methods: We searched title, abstract, and Medical Subject Headings term fields in 5 research databases (PubMed, EMBASE, Academic Search Premier, PsycINFO, and CINAHL) using terms combining parents or parenting (e.g., mother, father, caregiver, parenting style, food parenting) and obesity (e.g., obesity, body weight, overweight) or obesity-related lifestyle behaviors (e.g., diet, snacking, physical activity, outdoor play, exercise, media use).
Selection criteria: We identified and screened studies as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) published between January 2009 and December 2015, examining links between parenting and childhood obesity, including parents or caregivers as research participants, and written in English. We excluded interventions, nonhuman studies, dissertations, conference abstracts, and studies on youths with specific medical conditions. Of 5557 unique studies, 667 studies were eligible.
Data collection and analysis: For each of the 667 studies, 4 coders were trained to code characteristics of the study (e.g., publication year, geographic region, journal, study focus) and parent research participants (e.g., parent gender, demographic background, biological relationship with child, and residential status). We established intercoder reliability before coding the full sample of studies (mean Krippendorf's alpha = .79; average percentage agreement = 94%).
Main results: Of the studies, 1% included only fathers. By contrast, 36% included only mothers. Although slightly more than 50% of studies (n = 347) included at least 1 father, only 57 studies reported results for fathers separate from those for mothers. When we combined them with studies including only fathers, 10% of studies overall reported results for fathers. Samples sizes of fathers were small compared with mothers. Of studies with fathers, 59% included 50 or fewer fathers, whereas 22% of studies with mothers included 50 or fewer mothers. The mean sample size for fathers across all eligible studies was 139, compared with 672 for mothers. Overall, fathers represented 17% of parent participants across all eligible studies.
Conclusions: This study unequivocally demonstrates that fathers are underrepresented in recent observational research on parenting and childhood obesity. Public health implications. The underrepresentation of fathers in obesity research compromises the development of effective family interventions for childhood obesity prevention. Targeted opportunities and incentives are needed to support research with fathers.

Child & adolescent health · randomised controlled trial Metabolic and bariatric surgery versus intensive non-surgical treatment for adolescents with severe obesity (AMOS2): a multicentre, randomised, controlled trial in Sweden.
Background: Severe obesity in adolescents has a profound impact on current and future health. Metabolic and bariatric surgery (MBS) is increasingly used in adolescents internationally. However, to our knowledge, there are no randomised trials examining the currently most used surgical techniques. Our aim was to evaluate changes in BMI and secondary health and safety outcomes after MBS.
Methods: The Adolescent Morbid Obesity Surgery 2 (AMOS2) study is a randomised, open-label, multicentre trial done at three university hospitals in Sweden (located in Stockholm, Gothenburg, and Malmö). Adolescents aged 13-16 years with a BMI of at least 35 kg/m2, who had attended treatment for obesity for at least 1 year, passed assessments from a paediatric psychologist and a paediatrician, and had a Tanner pubertal stage of at least 3, were randomly assigned (1:1) to MBS or intensive non-surgical treatment. Exclusion criteria included monogenic or syndromic obesity, major psychiatric illness, and regular self-induced vomiting. Computerised randomisation was stratified for sex and recruitment site. Allocation was concealed for both staff and participants until the end of the inclusion day, and then all participants were unmasked to treatment intervention. One group underwent MBS (primarily gastric bypass), while the other group received intensive non-surgical treatment starting with 8 weeks of low-calorie diet. The primary outcome was 2-year change in BMI, analysed as intention-to-treat. The trial is registered at ClinicalTrials.gov, NCT02378259.
Findings: 500 people were assessed for eligibility between Aug 27, 2014, and June 7, 2017. 450 participants were excluded (397 did not meet inclusion criteria, 39 declined to participate, and 14 were excluded for various other reasons). Of the 50 remaining participants, 25 (19 females and six males) were randomly assigned to receive MBS and 25 (18 females and seven males) were assigned to intensive non-surgical treatment. Three participants (6%; one in the MBS group and two in the intensive non-surgical treatment group) did not participate in the 2-year follow-up, and in total 47 (94%) participants were assessed for the primary endpoint. Mean age of participants was 15·8 years (SD 0·9) and mean BMI at baseline was 42·6 kg/m2 (SD 5·2). After 2 years, BMI change was -12·6 kg/m2 (-35·9 kg; n=24) among adolescents undergoing MBS (Roux-en-Y gastric bypass [n=23], sleeve gastrectomy [n=2]) and -0·2 kg/m2 (0·4 kg; [n=23]) among participants in the intensive non-surgical treatment group (mean difference -12·4 kg/m2 [95% CI -15·5 to -9·3]; p<0·0001). Five (20%) patients in the intensive non-surgical group crossed over to MBS during the second year. Adverse events (n=4) after MBS were mild but included one cholecystectomy. Regarding safety outcomes, surgical patients had a reduction in bone mineral density, while controls were unchanged after 2 years (z-score change mean difference -0·9 [95% CI -1·2 to -0·6]). There were no significant differences between the groups in vitamin and mineral levels, gastrointestinal symptoms (except less reflux in the surgical group), or in mental health at the 2-year follow-up.
Interpretation: MBS is an effective and well tolerated treatment for adolescents with severe obesity resulting in substantial weight loss and improvements in several aspects of metabolic health and physical quality of life over 2 years, and should be considered in adolescents with severe obesity.

Solberg LI, Crain AL, Maciosek MV, Unützer J, Ohnsorg KA, Beck A, Rubenstein L, Whitebird RR, Rossom RC, Pietruszewski PB, Crabtree BF, Joslyn K, Van de Ven A, Glasgow RE. (2015)MEDLINE-indexed journal, not yet read by usAnnals of family medicine · randomised controlled trial A stepped-wedge evaluation of an initiative to spread the collaborative care model for depression in primary care.
Purpose: Scale-up and spread of evidence-based practices is one of the most important challenges facing health care. We tested whether a statewide initiative, Depression Improvement Across Minnesota-Offering a New Direction (DIAMOND), to implement the collaborative care model for depression in 75 primary care clinics resulted in patient outcome improvements corresponding to those reported in randomized controlled trials.
Methods: Health plans provided a new monthly payment to participating clinics after a 6-month intensive training program with ongoing data submission, networking, and consultation. Implementation was staggered, with 5 sequences of 10 to 40 clinics every 6 months. Payers provided weekly contact information for members from participating clinics who were filling antidepressant prescriptions, and we conducted baseline and 6-month surveys of 1,578 patients about their care and outcomes.
Results: There were 466 patients in DIAMOND clinics who received usual care before implementation (UCB), 559 who received usual care in DIAMOND clinics after implementation (UCA), 245 who received DIAMOND care after implementation (DCA), and 308 who received usual care in comparison clinics (UC). Patients who received DIAMOND care after implementation reported more collaborative care depression services than the 3 comparison groups (10.9 vs 6.4-6.7, on a scale of 0 of 14, where higher numbers indicate more services; P <.001) and more satisfaction with their care (4.0 vs 3.4 on a scale 1 to 5, in which higher scores indicate higher satisfaction; P ≤.001). Depression remission rates, however, were not significantly different among the 4 groups (36.4% DCA vs 35.8% UCB, 35.0% UCA, 33.9% UC; P = .94).
Conclusions: Despite the incentive of a supporting payment change and intensive training and support for clinics volunteering to participate, no difference in depression outcomes was documented. Specific unmeasured actions present in trials but not present in these clinics may be critical for successful outcome improvement.

Blumberger DM, Vila-Rodriguez F, Thorpe KE, Feffer K, Noda Y, Giacobbe P, Knyahnytska Y, Kennedy SH, Lam RW, Daskalakis ZJ, Downar J. (2018)MEDLINE-indexed journal, not yet read by usLancet (London, England) · randomised controlled trial Effectiveness of theta burst versus high-frequency repetitive transcranial magnetic stimulation in patients with depression (THREE-D): a randomised non-inferiority trial.
Background: Treatment-resistant major depressive disorder is common; repetitive transcranial magnetic stimulation (rTMS) by use of high-frequency (10 Hz) left-side dorsolateral prefrontal cortex stimulation is an evidence-based treatment for this disorder. Intermittent theta burst stimulation (iTBS) is a newer form of rTMS that can be delivered in 3 min, versus 37·5 min for a standard 10 Hz treatment session. We aimed to establish the clinical effectiveness, safety, and tolerability of iTBS compared with standard 10 Hz rTMS in adults with treatment-resistant depression.
Methods: In this randomised, multicentre, non-inferiority clinical trial, we recruited patients who were referred to specialty neurostimulation centres based at three Canadian university hospitals (Centre for Addiction and Mental Health and Toronto Western Hospital, Toronto, ON, and University of British Columbia Hospital, Vancouver, BC). Participants were aged 18-65 years, were diagnosed with a current treatment-resistant major depressive episode or could not tolerate at least two antidepressants in the current episode, were receiving stable antidepressant medication doses for at least 4 weeks before baseline, and had an HRSD-17 score of at least 18. Participants were randomly allocated (1:1) to treatment groups (10 Hz rTMS or iTBS) by use of a random permuted block method, with stratification by site and number of adequate trials in which the antidepressants were unsuccessful. Treatment was delivered open-label but investigators and outcome assessors were masked to treatment groups. Participants were treated with 10 Hz rTMS or iTBS to the left dorsolateral prefrontal cortex, administered on 5 days a week for 4-6 weeks. The primary outcome measure was change in 17-item Hamilton Rating Scale for Depression (HRSD-17) score, with a non-inferiority margin of 2·25 points. For the primary outcome measure, we did a per-protocol analysis of all participants who were randomly allocated to groups and who attained the primary completion point of 4 weeks. This trial is registered with ClinicalTrials.gov, number NCT01887782.
Findings: Between Sept 3, 2013, and Oct 3, 2016, we randomly allocated 205 participants to receive 10 Hz rTMS and 209 participants to receive iTBS. 192 (94%) participants in the 10 Hz rTMS group and 193 (92%) in the iTBS group were assessed for the primary outcome after 4-6 weeks of treatment. HRSD-17 scores improved from 23·5 (SD 4·4) to 13·4 (7·8) in the 10 Hz rTMS group and from 23·6 (4·3) to 13·4 (7·9) in the iTBS group (adjusted difference 0·103 [corrected], lower 95% CI -1·16; p=0·0011), which indicated non-inferiority of iTBS. Self-rated intensity of pain associated with treatment was greater in the iTBS group than in the 10 Hz rTMS group (mean score on verbal analogue scale 3·8 [SD 2·0] vs 3·4 [2·0] out of 10; p=0·011). Dropout rates did not differ between groups (10 Hz rTMS: 13 [6%] of 205 participants; iTBS: 16 [8%] of 209 participants); p=0·6004). The most common treatment-related adverse event was headache in both groups (10 Hz rTMS: 131 [64%] of 204; iTBS: 136 [65%] of 208).
Interpretation: In patients with treatment-resistant depression, iTBS was non-inferior to 10 Hz rTMS for the treatment of depression. Both treatments had low numbers of dropouts and similar side-effects, safety, and tolerability profiles. By use of iTBS, the number of patients treated per day with current rTMS devices can be increased several times without compromising clinical effectiveness.

(2021)MEDLINE-indexed journal, not yet read by usThe lancet. Diabetes & endocrinology · randomised controlled trial A community-based, multi-level, multi-setting, multi-component intervention to reduce weight gain among low socioeconomic status Latinx children with overweight or obesity: The Stanford GOALS randomised controlled trial.
Background: There are few long-term studies of interventions to reduce in low socioeconomic status children with overweight or obesity. The Stanford GOALS trial evaluated a 3-year, community-based, multi-level, multi-setting, multi-component (MMM) systems intervention, to reduce weight gain among low socioeconomic status, Latinx children with overweight or obesity.
Methods: We did a two-arm, parallel group, randomised, open-label, active placebo-controlled trial with masked assessment over 3 years. Families from low-income, primarily Latinx communities in Northern California, CA, USA, with 7-11-year-old children with overweight or obesity were randomly assigned to a MMM intervention or a Health Education (HE) comparison intervention. The MMM intervention included home environment changes and behavioural counselling, community after school team sports, and reports to primary health-care providers. The primary outcome was child BMI trajectory over three years. Secondary outcomes included one- and two-year changes in BMI. This trial is registered with ClinicalTrials.govNCT01642836.
Findings: Between July 13, 2012, and Oct 3, 2013, 241 families were recruited and randomly assigned to MMM (n=120) or HE (n=121). Children's mean age was 9·5 (SD 1·4) years, 134 (56%) were female and 107 (44%) were male, and 236 (98%) were Latinx. 238 (99%) children participated in year 1, 233 (97%) in year 2, and 227 (94%) in year 3 of follow-up assessments. In intention-to-treat analysis, over 3 years, the difference between intervention groups in BMI trajectory was not significant (mean adjusted difference -0·25 [95% CI -0·90 to 0·40] kg/m2; Cohen's d=0.10; p=0·45). Children in the MMM intervention group gained less BMI over 1 year than did children in the HE intervention group (-0·73 [-1·07 to -0·39] kg/m2, d=0.55); the same was true over 2 years (-0·63 [-1·13 to -0·14] kg/m2; d =0.33). No differential adverse events were observed.
Interpretation: The MMM intervention did not reduce BMI gain versus HE over 3 years but the effects over 1 and 2 years in this rigorous trial show the promise of this systems intervention approach for reducing weight gain and cardiometabolic risk factors in low socioeconomic status communities.

Feasibility and preliminary efficacy of the 'HEYMAN' healthy lifestyle program for young men: a pilot randomised controlled trial.
Background: In young men, unhealthy lifestyle behaviours can be detrimental to their physical and/or mental health and set them on a negative health trajectory into adulthood. Despite this, there is a lack of evidence to guide development of effective health behaviour change interventions for young men. This study assessed the feasibility and preliminary efficacy of the 'HEYMAN' (Harnessing Ehealth to enhance Young men's Mental health, Activity and Nutrition) healthy lifestyle program for young men.
Methods: A pilot RCT with 50 young men aged 18-25 years randomised to the HEYMAN intervention (n = 26) or waitlist control (n = 24). HEYMAN was a 3-month intervention, targeted for young men to improve eating habits, activity levels and well-being. Intervention development was informed by a participatory research model (PRECEDE-PROCEED). Intervention components included eHealth support (website, wearable device, Facebook support group), face-to-face sessions (group and individual), a personalised food and nutrient report, home-based resistance training equipment and a portion control tool. Outcomes included: feasibility of research procedures (recruitment, randomisation, data collection and retention) and of intervention components. Generalized linear mixed models estimated the treatment effect at 3-months for the primary outcomes: pedometer steps/day, diet quality, well-being and several secondary outcomes.
Results: A 7-week recruitment period was required to enrol 50 young men. A retention rate of 94% was achieved at 3-months post-intervention. Retained intervention participants (n = 24) demonstrated reasonable usage levels for most program components and also reported reasonable levels of program component acceptability for attractiveness, comprehension, usability, support, satisfaction and ability to persuade, with scores ranging from 3.0 to 4.6 (maximum 5). No significant intervention effects were observed for the primary outcomes of steps/day (1012.7, 95% CI = -506.2, 2531.6, p = 0.191, d = 0.36), diet quality score (3.6, 95% CI = -0.4, 7.6, p = 0.081, d = 0.48) or total well-being score (0.4, 95% CI = -1.6, 2.5, p = 0.683, d = 0.11). Significant intervention effects were found for daily vegetable servings, energy-dense, nutrient-poor foods, MVPA, weight, BMI, fat mass, waist circumference and cholesterol (all p < 0.05).
Conclusions: The HEYMAN program demonstrated feasibility in assisting young men to make some positive lifestyle changes. This provides support for the conduct of a larger, fully-powered RCT, but with minor amendments to research procedures and intervention components required.

(2015)MEDLINE-indexed journal, not yet read by usThe Lancet. Infectious diseases · randomised controlled trial Inactivated poliovirus vaccine given alone or in a sequential schedule with bivalent oral poliovirus vaccine in Chilean infants: a randomised, controlled, open-label, phase 4, non-inferiority study.
Background: Bivalent oral poliovirus vaccine (bOPV; types 1 and 3) is expected to replace trivalent OPV (tOPV) globally by April, 2016, preceded by the introduction of at least one dose of inactivated poliovirus vaccine (IPV) in routine immunisation programmes to eliminate vaccine-associated or vaccine-derived poliomyelitis from serotype 2 poliovirus. Because data are needed on sequential IPV-bOPV schedules, we assessed the immunogenicity of two different IPV-bOPV schedules compared with an all-IPV schedule in infants.
Methods: We did a randomised, controlled, open-label, non-inferiority trial with healthy, full-term (>2·5 kg birthweight) infants aged 8 weeks (± 7 days) at six well-child clinics in Santiago, Chile. We used supplied lists to randomly assign infants (1:1:1) to receive three polio vaccinations (IPV by injection or bOPV as oral drops) at age 8, 16, and 24 weeks in one of three sequential schedules: IPV-bOPV-bOPV, IPV-IPV-bOPV, or IPV-IPV-IPV. We did the randomisation with blocks of 12 stratified by study site. All analyses were done in a masked manner. Co-primary outcomes were non-inferiority of the bOPV-containing schedules compared with the all-IPV schedule for seroconversion (within a 10% margin) and antibody titres (within two-thirds log2 titres) to poliovirus serotypes 1 and 3 at age 28 weeks, analysed in the per-protocol population. Secondary outcomes were seroconversion and titres to serotype 2 and faecal shedding for 4 weeks after a monovalent OPV type 2 challenge at age 28 weeks. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01841671, and is closed to new participants.
Findings: Between April 25 and August 1, 2013, we assigned 570 infants to treatment: 190 to IPV-bOPV-bOPV, 192 to IPV-IPV-bOPV, and 188 to IPV-IPV-IPV. 564 (99%) were vaccinated and included in the intention-to-treat cohort, and 537 (94%) in the per-protocol analyses. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroconversion to type 1 poliovirus were 166 (98·8%) of 168, 95% CI 95·8-99·7; 178 (100%), 97·9-100·0; and 175 (100%), 97·9-100·0. Proportions with seroconvsion to type 3 poliovirus were 163 (98·2%) of 166, 94·8-99·4; 177 (100%), 97·9-100·0, and 172 (98·9%) of 174, 95·9-99·7. Non-inferiority was thus shown for the bOPV-containing schedules compared with the all-IPV schedule, with no significant differences between groups. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroprotective antibody titres to type 1 poliovirus were 168 (98·8%) of 170, 95% CI 95·8-99·7; 181 (100%), 97·9-100·0; and 177 (100%), 97·9-100·0. Proportions to type 3 poliovirus were 166 (98·2%) of 169, 94·9-99·4; 180 (100%), 97·9-100·0; and 174 (98·9%) of 176, 96·0-99·7. Non-inferiority comparisons could not be done for this outcome because median titres for the groups receiving OPV were greater than the assay's upper limit of detection (log2 titres >10·5). The proportions of children seroconverting to type 2 poliovirus in the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, were 130 (77·4%) of 168, 95% CI 70·5-83·0; 169 (96·0%) of 176, 92·0-98·0; and 175 (100%), 97·8-100. IPV-bOPV schedules resulted in almost a 0·3 log reduction of type 2 faecal shedding compared with the IPV-only schedule. No participants died during the trial; 81 serious adverse events were reported, of which one was thought to be possibly vaccine-related (intestinal intussusception).
Interpretation: Seroconversion rates against polioviruses types 1 and 3 were non-inferior in sequential schedules containing IPV and bOPV, compared with an all-IPV schedule, and proportions of infants with protective antibodies were high after all three schedules. One or two doses of bOPV after IPV boosted intestinal immunity for poliovirus type 2, suggesting possible cross protection. Additionally, there was evidence of humoral priming for type 2 from one dose of IPV. Our findings could give policy makers flexibility when choosing a vaccination schedule, especially when trying to eliminate vaccine-associated and vaccine-derived poliomyelitis.

Effect of the Promoting Resilience in Stress Management Intervention for Parents of Children With Cancer (PRISM-P): A Randomized Clinical Trial.
Importance: Parents of children with serious illness, such as cancer, experience high stress and distress. Few parent-specific psychosocial interventions have been evaluated in randomized trials.
Objective: To determine if individual- or group-based delivery of a novel intervention called Promoting Resilience in Stress Management for Parents (PRISM-P) improves parent-reported resilience compared with usual care.
Design, setting, and participants: This parallel, phase 2 randomized clinical trial with enrollment from December 2016 through December 2018 and 3-month follow-up was conducted at Seattle Children's Hospital. English-speaking parents or guardians of children who were 2 to 24 years old, who had received a diagnosis of a new malignant neoplasm 1 to 10 weeks prior to enrollment, and who were receiving cancer-directed therapy at Seattle Children's Hospital were included. Parents were randomized 1:1:1 to the one-on-one or group PRISM-P intervention or to usual care. Data were analyzed in 2019 (primary analyses from January to March 2019; final analyses in July 2019).
Interventions: The PRISM-P is a manualized, brief intervention targeting 4 skills: stress management, goal setting, cognitive reframing, and meaning making. For one-on-one delivery, skills were taught privately and in person for 30 to 60 minutes approximately every other week. For group delivery, the same skills were taught in a single session with at least 2 parents present.
Main outcomes and measures: Participants completed patient-reported outcome surveys at enrollment and at 3 months. Linear regression modeling evaluated associations in the intention-to-treat population between each delivery format and the primary outcome (Connor-Davidson Resilience Scale scores, ranging from 0 to 40, with higher scores reflecting greater resilience) and secondary outcomes (benefit finding, social support, health-related quality of life, stress, and distress) at 3 months.
Results: In total, 94 parents enrolled, were randomized to 1 of the 3 groups, and completed baseline surveys (32 parents in one-on-one sessions, 32 in group sessions, and 30 in usual care). Their median (interquartile range) ages were 35 to 38 (31-44) years across the 3 groups, and they were predominantly white, college-educated mothers. Their children had median (interquartile range) ages of 5 to 8 (3-14) years; slightly more than half of the children were boys, and the most common cancer type was leukemia or lymphoma. One-on-one PRISM-P delivery was significantly associated with improvement compared with usual care in parent-reported outcomes for resilience (β, 2.3; 95% CI, 0.1-4.6; P = .04) and for benefit finding (β, 0.5; 95% CI, 0.2-0.8; P = .001). No significant associations were detected between either platform and other parent-reported outcomes.
Conclusions and relevance: When delivered individually, PRISM-P was associated with improved parent-reported resilience and benefit finding. This scalable psychosocial intervention may help parents cope and find meaning after their child receives a diagnosis of a serious illness.

(2021)MEDLINE-indexed journal, not yet read by usJAMA pediatrics · randomised controlled trial Effect of Family Navigation on Diagnostic Ascertainment Among Children at Risk for Autism: A Randomized Clinical Trial From DBPNet.
Importance: Early identification of autism spectrum disorder (ASD) is associated with improved cognitive and behavioral outcomes. Targeted strategies are needed to support equitable access to diagnostic services to ensure that children from low-income and racial/ethnic minority families receive the benefits of early ASD identification and treatment.
Objective: To test the efficacy of family navigation (FN), an individually tailored, culturally informed care management strategy, to increase the likelihood of achieving diagnostic ascertainment among young children at risk for ASD.
Design, setting, and participants: This randomized clinical trial of 249 families of children aged 15 to 27 months who had positive screening results for possible ASD was conducted in 11 urban primary care sites in 3 cities. Data collection occurred from February 24, 2015, through November 5, 2018. Statistical analysis was performed on an intent-to-treat basis from November 5, 2018, to July 27, 2020.
Interventions: Families were randomized to FN or conventional care management (CCM). Families receiving FN were assigned a navigator who conducted community-based outreach to families to address structural barriers to care and support engagement in recommended services. Families receiving CCM were assigned to a care manager, who did limited telephone outreach. Families received FN or CCM after positive initial screening results and for 100 days after diagnostic ascertainment.
Main outcomes and measures: The primary outcome, diagnostic ascertainment, was measured as the number of days from randomization to completion of the child's clinical developmental evaluation, when a diagnosis of ASD or other developmental disorder was determined.
Results: Among 250 families randomized, 249 were included in the primary analysis (174 boys [69.9%]; mean [SD] age, 22.0 [3.5] months; 205 [82.3%] publicly insured; 233 [93.6%] non-White). Children who received FN had a greater likelihood of reaching diagnostic ascertainment over the course of 1 year (FN, 108 of 126 [85.7%]; CCM, 94 of 123 [76.4%]; unadjusted hazard ratio [HR], 1.39 [95% CI, 1.05-1.84]). Site (Boston, New Haven, and Philadelphia) and ethnicity (Hispanic vs non-Hispanic) moderated the effect of FN (treatment × site interaction; P = .03; Boston: HR, 2.07 [95% CI, 1.31-3.26]; New Haven: HR, 1.91 [95% CI, 0.94-3.89]; and Philadelphia: HR, 0.91 [95% CI, 0.60-1.37]) (treatment × ethnicity interaction; P < .001; Hispanic families: HR, 2.81 [95% CI, 2.23-3.54] vs non-Hispanic families: HR, 1.49 [95% CI, 1.45-1.53]). The magnitude of FN's effect was significantly greater among Hispanic families than among non-Hispanic families (diagnostic ascertainment among Hispanic families: FN, 90.9% [30 of 33], and CCM, 53.3% [16 of 30]; vs non-Hispanic families: FN, 89.7% [35 of 39], and CCM, 77.5% [31 of 40]).
Conclusions and relevance: Family navigation improved the likelihood of diagnostic ascertainment among children from racial/ethnic minority, low-income families who were detected as at risk for ASD in primary care. Results suggest differential effects of FN by site and ethnicity.

Do Parents Benefit From Help When Completing a Self-Guided Parenting Program Online? A Randomized Controlled Trial Comparing Triple P Online With and Without Telephone Support.
In response to recent increases in the dissemination of Web-based parenting supports, an important consideration is whether the core benefits of self-directed participation in online parenting interventions are counterbalanced by issues such as high dropout and noncompletion rates commonly reported within the Internet intervention literature. This study outlines a randomized controlled trial of Triple P Online, a Web-based variant of the Triple P-Positive Parenting Program, delivered with varied levels of support scaffolding. Participants were 183 parents of children between 1 and 8 years of age with concerns about their child's behavior and at least one area of disadvantage or family difficulty. Participants were randomized to self-directed Triple P Online, telephone-supported Triple P Online, or a wait-list control. Primary outcomes measured at baseline, postintervention, and 5-month follow-up were negative parenting styles and child behavior problems. Secondary outcomes included parent confidence, anger, and adjustment; relationship quality; program engagement; and parent satisfaction. Self-directed participants showed short-term treatment effects, including reductions in overall negative parenting and frequency of child behavior problems, while practitioner support led to greater improvements in negative parenting and intensity of difficult child behaviors. Participants in the supported condition were also more likely to complete modules and reported greater program satisfaction. At follow-up, 50% of outcomes for the self-directed condition were significantly better than the control, while 94% of outcomes were significantly better than the control in the practitioner-supported condition. Although self-directed online approaches to parenting intervention are promising, this research highlights how minimal support can improve effective engagement and enhance outcomes for families.

Psychiatry · randomised controlled trial Smoking cessation for people with severe mental illness (SCIMITAR+): a pragmatic randomised controlled trial.
Background: People with severe mental illnesses such as schizophrenia are three times more likely to smoke than the wider population, contributing to widening health inequalities. Smoking remains the largest modifiable risk factor for this health inequality, but people with severe mental illness have not historically engaged with smoking cessation services. We aimed to test the effectiveness of a combined behavioural and pharmacological smoking cessation intervention targeted specifically at people with severe mental illness.
Methods: In the smoking cessation intervention for severe mental illness (SCIMITAR+) trial, a pragmatic, randomised controlled study, we recruited heavy smokers with bipolar disorder or schizophrenia from 16 primary care and 21 community-based mental health sites in the UK. Participants were eligible if they were aged 18 years or older, and smoked at least five cigarettes per day. Exclusion criteria included substantial comorbid drug or alcohol problems and people who lacked capacity to consent at the time of recruitment. Using computer-generated random numbers, participants were randomly assigned (1:1) to a bespoke smoking cessation intervention or to usual care. Participants, mental health specialists, and primary care physicians were unmasked to assignment. The bespoke smoking cessation intervention consisted of behavioural support from a mental health smoking cessation practitioner and pharmacological aids for smoking cessation, with adaptations for people with severe mental illness-such as, extended pre-quit sessions, cut down to quit, and home visits. Access to pharmacotherapy was via primary care after discussion with the smoking cessation specialist. Under usual care participants were offered access to local smoking cessation services not specifically designed for people with severe mental illnesses. The primary endpoint was smoking cessation at 12 months ascertained via carbon monoxide measurements below 10 parts per million and self-reported cessation for the past 7 days. Secondary endpoints were biologically verified smoking cessation at 6 months; number of cigarettes smoked per day, Fagerström Test for Nicotine Dependence (FTND) and Motivation to Quit (MTQ) questionnaire; general and mental health functioning determined via the Patient Health Questionnaire-9 (PHQ-9), the Generalised Anxiety Disorder-7 (GAD-7) questionnaire, and 12-Item Short Form Health Survey (SF-12); and body-mass index (BMI). This trial was registerd with the ISRCTN registry, number ISRCTN72955454, and is complete.
Findings: Between Oct 7, 2015, and Dec 16, 2016, 526 eligible patients were randomly assigned to the bespoke smoking cessation intervention (n=265) or usual care (n=261). 309 (59%) participants were male, median age was 47·2 years (IQR 36·3-54·5), with high nicotine dependence (mean 24 cigarettes per day [SD 13·2]), and the most common severe mental disorders were schizophrenia or other psychotic illness (n=343 [65%]), bipolar disorder (n=115 [22%]), and schizoaffective disorder (n=66 [13%]). 234 (88%) of intervention participants engaged with the treatment programme and attended 6·4 (SD 3·5) quit smoking sessions, with an average duration of 39 min (SD 17; median 35 min, range 5-120). Verified quit data at 12 months were available for 219 (84%) of 261 usual care and 223 (84%) of 265 intervention participants. The proportion of participants who had quit at 12 months was higher in the intervention group than in the usual care group, but non-significantly (34 [15%] of 223 [13% of those assigned to group] vs 22 [10%] of 219 [8% of those assigned to group], risk difference 5·2%, 95% CI -1·0 to 11·4; odds ratio [OR] 1·6, 95% CI 0·9 to 2·9; p=0·10). The proportion of participants who quit at 6 months was significantly higher in the intervention group than in the usual care group (32 [14%] of 226 vs 14 [6%] of 217; risk difference 7·7%, 95% CI 2·1 to 13·3; OR 2·4, 95% CI 1·2 to 4·6; p=0·010). The incidence rate ratio for number of cigarettes smoked per day at 6 months was 0·90 (95% CI 0·80 to 1·01; p=0·079), and at 12 months was 1·00 (0·89 to 1·13; p=0·95). At both 6 months and 12 months, the intervention group was non-significantly favoured in the FTND (adjusted mean difference 6 months -0·18, 95% CI -0·53 to 0·17, p=0·32; and 12 months -0·01, -0·39 to 0·38, p=0·97) and MTQ questionnaire (adjusted mean difference 0·58, -0·01 to 1·17, p=0·056; and 12 months 0·64, 0·04 to 1·24, p=0·038). The PHQ-9 showed no difference between the groups (adjusted mean difference at 6 months 0·20, 95% CI -0·85 to 1·24 vs 12 months -0·12, -1·18 to 0·94). For the SF-12 survey, we saw evidence of improvement in physical health in the intervention group at 6 months (adjusted mean difference 1·75, 95% CI 0·21 to 3·28), but this difference was not evident at 12 months (0·59, -1·07 to 2·26); and we saw no difference in mental health between the groups at 6 or 12 months (adjusted mean difference at 6 months -0·73, 95% CI -2·82 to 1·36, and 12 months -0·41, -2·35 to 1·53). The GAD-7 questionnaire showed no difference between the groups (adjusted mean difference at 6 months -0·32 95% CI -1·26 to 0·62 vs 12 months -0·10, -1·05 to 0·86). No difference in BMI was seen between the groups (adjusted mean difference 6 months 0·16, 95% CI -0·54 to 0·85; 12 months 0·25, -0·62 to 1·13).
Interpretation: This bespoke intervention is a candidate model of smoking cessation for clinicians and policy makers to address high prevalence of smoking. The incidence of quitting at 6 months shows that smoking cessation can be achieved, but the waning of this effect by 12 months means more effort is needed for sustained quitting.

(2016)MEDLINE-indexed journal, not yet read by usLancet (London, England) · randomised controlled trial Effects of evidence-based strategies to reduce the socioeconomic gradient of uptake in the English NHS Bowel Cancer Screening Programme (ASCEND): four cluster-randomised controlled trials.
Background: Uptake in the national colorectal cancer screening programme in England varies by socioeconomic status. We assessed four interventions aimed at reducing this gradient, with the intention of improving the health benefits of screening.
Methods: All people eligible for screening (men and women aged 60-74 years) across England were included in four cluster-randomised trials. Randomisation was based on day of invitation. Each trial compared the standard information with the standard information plus the following supplementary interventions: trial 1 (November, 2012), a supplementary leaflet summarising the gist of the key information; trial 2 (March, 2012), a supplementary narrative leaflet describing people's stories; trial 3 (June, 2013), general practice endorsement of the programme on the invitation letter; and trial 4 (July-August, 2013) an enhanced reminder letter with a banner that reiterated the screening offer. Socioeconomic status was defined by the Index of Multiple Deprivation score for each home address. The primary outcome was the socioeconomic status gradient in uptake across deprivation quintiles. This study is registered, number ISRCTN74121020.
Findings: As all four trials were embedded in the screening programme, loss to follow-up was minimal (less than 0·5%). Trials 1 (n=163,525) and 2 (n=150,417) showed no effects on the socioeconomic gradient of uptake or overall uptake. Trial 3 (n=265 434) showed no effect on the socioeconomic gradient but was associated with increased overall uptake (adjusted odds ratio [OR] 1·07, 95% CI 1·04-1·10, p<0·0001). In trial 4 (n=168 480) a significant interaction was seen with socioeconomic status gradient (p=0·005), with a stronger effect in the most deprived quintile (adjusted OR 1·11, 95% CI 1·04-1·20, p=0·003) than in the least deprived (1·00, 0·94-1·06, p=0·98). Overall uptake was also increased (1·07, 1·03-1·11, p=0·001).
Interpretation: Of four evidence-based interventions, the enhanced reminder letter reduced the socioeconomic gradient in screening uptake, but further reducing inequalities in screening uptake through written materials alone will be challenging.

IMPACT: Evaluation of a Controlled Organizational Intervention Using Influential Peers to Promote Professional Fulfillment.
Objective: To determine the effects of a popular opinion leader (POL)-led organizational intervention targeting all physicians and advanced practice providers (APPs) working within clinic groups on professional fulfillment (primary outcome), gratitude, burnout, self-valuation, and turnover intent.
Patients and methods: All 20 Stanford University HealthCare Alliance clinics with ≥5 physicians-APPs were matched by size and baseline gratitude scores and randomly assigned to immediate or delayed intervention (control). Between July 10, 2018, and March 15, 2019, trained POLs and a physician-PhD study investigator facilitated 4 interactive breakfast or lunch workshops at intervention clinics, where colleagues were invited to discuss and experience one evidence-based practice (gratitude, mindfulness, cognitive, and behavioral strategies). Participants in both groups completed incentivized annual assessments of professional fulfillment, workplace gratitude, burnout, self-valuation, and intent to leave as part of ongoing organizational program evaluation.
Results: Eighty-four (75%) physicians-APPs at intervention clinics attended at least 1 workshop. Of all physicians-APPs, 236 of 251 (94%) completed assessments in 2018 and 254 of 263 (97%) in 2019. Of 264 physicians-APPs with 2018 or 2019 assessment data, 222 (84%) had completed 2017 assessments. Modal characteristics were 60% female, 46% White, 49% aged 40 to 59 years, 44% practicing family-internal medicine, 78% living with partners, and 53% with children. Change in professional fulfillment by 2019 relative to average 2017 to 2018 levels was more favorable (0.63 points; effect size = 0.35; P=.001) as were changes in gratitude and intent to leave among clinicians practicing at intervention clinics.
Conclusion: Interventions led by respected physicians-APPs can achieve high participation rates and have potential to promote well-being among their colleagues.

(2014)MEDLINE-indexed journal, not yet read by usLancet (London, England) · randomised controlled trial Early palliative care for patients with advanced cancer: a cluster-randomised controlled trial.
Background: Patients with advanced cancer have reduced quality of life, which tends to worsen towards the end of life. We assessed the effect of early palliative care in patients with advanced cancer on several aspects of quality of life.
Methods: The study took place at the Princess Margaret Cancer Centre (Toronto, ON, Canada), between Dec 1, 2006, and Feb 28, 2011. 24 medical oncology clinics were cluster randomised (in a 1:1 ratio, using a computer-generated sequence, stratified by clinic size and tumour site [four lung, eight gastrointestinal, four genitourinary, six breast, two gynaecological]), to consultation and follow-up (at least monthly) by a palliative care team or to standard cancer care. Complete masking of interventions was not possible; however, patients provided written informed consent to participate in their own study group, without being informed of the existence of another group. Eligible patients had advanced cancer, European Cooperative Oncology Group performance status of 0-2, and a clinical prognosis of 6-24 months. Quality of life (Functional Assessment of Chronic Illness Therapy--Spiritual Well-Being [FACIT-Sp] scale and Quality of Life at the End of Life [QUAL-E] scale), symptom severity (Edmonton Symptom Assessment System [ESAS]), satisfaction with care (FAMCARE-P16), and problems with medical interactions (Cancer Rehabilitation Evaluation System Medical Interaction Subscale [CARES-MIS]) were measured at baseline and monthly for 4 months. The primary outcome was change score for FACIT-Sp at 3 months. Secondary endpoints included change score for FACIT-Sp at 4 months and change scores for other scales at 3 and 4 months. This trial is registered with ClinicalTrials.gov, number NCT01248624.
Findings: 461 patients completed baseline measures (228 intervention, 233 control); 393 completed at least one follow-up assessment. At 3-months, there was a non-significant difference in change score for FACIT-Sp between intervention and control groups (3·56 points [95% CI -0·27 to 7·40], p=0·07), a significant difference in QUAL-E (2·25 [0·01 to 4·49], p=0·05) and FAMCARE-P16 (3·79 [1·74 to 5·85], p=0·0003), and no difference in ESAS (-1·70 [-5·26 to 1·87], p=0·33) or CARES-MIS (-0·66 [-2·25 to 0·94], p=0·40). At 4 months, there were significant differences in change scores for all outcomes except CARES-MIS. All differences favoured the intervention group.
Interpretation: Although the difference in quality of life was non-significant at the primary endpoint, this trial shows promising findings that support early palliative care for patients with advanced cancer.

(2020)MEDLINE-indexed journal, not yet read by usAnaesthesia, critical care & pain medicine · cohort or longitudinal SARS-CoV-2 in Spanish Intensive Care Units: Early experience with 15-day survival in Vitoria.
Purpose: Community transmission of SARS-CoV-2 was detected in Spain in February 2020, with 216% intensive care unit (ICU) capacity expanded in Vitoria by March 18th, 2020.
Methods: We identified patients from the two public hospitals in Vitoria who were admitted to ICU with confirmed infection by SARS-CoV-2. Data reported here were available in April 6th, 2020. Mortality was assessed in those who completed 15-days of ICU stay.
Results: We identified 48 patients (27 males) with confirmed SARS-CoV-2. Median [interquartile range (IQR)] age of patients was 63 [51-75] years. Symptoms began a median of 7 [5-12] days before ICU admission. The most common comorbidities identified were obesity (48%), arterial hypertension (44%) and chronic lung disease (37%). All patients were admitted by hypoxemic respiratory failure and none received non-invasive mechanical ventilation. Forty-five (94%) underwent intubation, 3 (6%) high flow nasal therapy (HFNT), 1 (2%) extracorporeal membrane oxygenation (ECMO) and 22 (46%) required prone position. After 15 days, 14/45 (31%) intubated patients died (13% within one week), 10/45 (22%) were extubated, and 21/45 (47%) underwent mechanical ventilation. Six patients had documented super-infection. Procalcitonin plasma above 0.5μg/L was associated with 16% vs. 19% (p=0.78) risk of death after 7 days.
Conclusion: This early experience with SARS-CoV-2 in Spain suggests that a strategy of right oxygenation avoiding non-invasive mechanical ventilation was life-saving. Seven-day mortality in SARS-CoV-2 requiring intubation was lower than 15%, with 80% of patients still requiring mechanical ventilation. After 15 days of ICU admission, half of patients remained intubated, whereas one third died.

Background: In recent years, advances in technology have led to an influx of mental health apps, in particular the development of mental health and well-being chatbots, which have already shown promise in terms of their efficacy, availability, and accessibility. The ChatPal chatbot was developed to promote positive mental well-being among citizens living in rural areas. ChatPal is a multilingual chatbot, available in English, Scottish Gaelic, Swedish, and Finnish, containing psychoeducational content and exercises such as mindfulness and breathing, mood logging, gratitude, and thought diaries.
Objective: The primary objective of this study is to evaluate a multilingual mental health and well-being chatbot (ChatPal) to establish if it has an effect on mental well-being. Secondary objectives include investigating the characteristics of individuals that showed improvements in well-being along with those with worsening well-being and applying thematic analysis to user feedback.
Methods: A pre-post intervention study was conducted where participants were recruited to use the intervention (ChatPal) for a 12-week period. Recruitment took place across 5 regions: Northern Ireland, Scotland, the Republic of Ireland, Sweden, and Finland. Outcome measures included the Short Warwick-Edinburgh Mental Well-Being Scale, the World Health Organization-Five Well-Being Index, and the Satisfaction with Life Scale, which were evaluated at baseline, midpoint, and end point. Written feedback was collected from participants and subjected to qualitative analysis to identify themes.
Results: A total of 348 people were recruited to the study (n=254, 73% female; n=94, 27% male) aged between 18 and 73 (mean 30) years. The well-being scores of participants improved from baseline to midpoint and from baseline to end point; however, improvement in scores was not statistically significant on the Short Warwick-Edinburgh Mental Well-Being Scale (P=.42), the World Health Organization-Five Well-Being Index (P=.52), or the Satisfaction With Life Scale (P=.81). Individuals that had improved well-being scores (n=16) interacted more with the chatbot and were significantly younger compared to those whose well-being declined over the study (P=.03). Three themes were identified from user feedback, including "positive experiences," "mixed or neutral experiences," and "negative experiences." Positive experiences included enjoying exercises provided by the chatbot, while most of the mixed, neutral, or negative experiences mentioned liking the chatbot overall, but there were some barriers, such as technical or performance errors, that needed to be overcome.
Conclusions: Marginal improvements in mental well-being were seen in those who used ChatPal, albeit nonsignificant. We propose that the chatbot could be used along with other service offerings to complement different digital or face-to-face services, although further research should be carried out to confirm the effectiveness of this approach. Nonetheless, this paper highlights the need for blended service offerings in mental health care.

Objective: This report describes persistent symptoms associated with post-acute COVID-19 syndrome (PACS) and the impact of these symptoms on physical function, cognitive function, health-related quality of life, and participation.
Design: This study used a cross-sectional observational study design. Patients attending Mount Sinai's post-acute COVID-19 syndrome clinic completed surveys containing patient-reported outcomes.
Results: A total of 156 patients completed the survey, at a median (range) time of 351 days (82-457 days) after COVID-19 infection. All patients were prevaccination. The most common persistent symptoms reported were fatigue (n = 128, 82%), brain fog (n = 105, 67%), and headache (n = 94, 60%). The most common triggers of symptom exacerbation were physical exertion (n = 134, 86%), stress (n = 107, 69%), and dehydration (n = 77, 49%). Increased levels of fatigue (Fatigue Severity Scale) and dyspnea (Medical Research Council) were reported, alongside reductions in levels of regularly completed physical activity. Ninety-eight patients (63%) scored for at least mild cognitive impairment (Neuro-Qol), and the domain of the EuroQol: 5 dimension, 5 level most impacted was Self-care, Anxiety/Depression and Usual Activities.
Conclusions: Persistent symptoms associated with post-acute COVID-19 syndrome seem to impact physical and cognitive function, health-related quality of life, and participation in society. More research is needed to further clarify the relationship between COVID-19 infection and post-acute COVID-19 syndrome symptoms, the underlying mechanisms, and treatment options.

(2013)MEDLINE-indexed journal, not yet read by usBiological psychiatry · clinical trial Rapid and longer-term antidepressant effects of repeated ketamine infusions in treatment-resistant major depression.
Background: Ketamine is reported to have rapid antidepressant effects; however, there is limited understanding of the time-course of ketamine effects beyond a single infusion. A previous report including 10 participants with treatment-resistant major depression (TRD) found that six ketamine infusions resulted in a sustained antidepressant effect. In the current report, we examined the pattern and durability of antidepressant effects of repeated ketamine infusions in a larger sample, inclusive of the original.
Methods: Participants with TRD (n = 24) underwent a washout of antidepressant medication followed by a series of up to six IV infusions of ketamine (.5 mg/kg) administered open-label three times weekly over a 12-day period. Participants meeting response criteria were monitored for relapse for up to 83 days from the last infusion.
Results: The overall response rate at study end was 70.8%. There was a large mean decrease in Montgomery-Åsberg Depression Rating Scale score at 2 hours after the first ketamine infusion (18.9 ± 6.6, p < .001), and this decrease was largely sustained for the duration of the infusion period. Response at study end was strongly predicted by response at 4 hours (94% sensitive, 71% specific). Among responders, median time to relapse after the last ketamine infusion was 18 days.
Conclusions: Ketamine was associated with a rapid antidepressant effect in TRD that was predictive of a sustained effect. Future controlled studies will be required to identify strategies to maintain an antidepressant response among patients who benefit from a course of ketamine.

(2014)MEDLINE-indexed journal, not yet read by usCirugia espanola · cohort or longitudinal Spanish-Latin American multicenter study of attitudes toward organ donation among personnel from hospital healthcare centers.
Introduction: Hospital personnel are a group which has an influence on the opinion of the rest of the population about healthcare matters. Any unfavorable attitude of this group would be an obstacle to an increase in organ donation.
Objective: To analyze the attitude of hospital workers toward the donation of one's own organs in Spanish and Latin American hospitals and to determine the factors affecting this attitude.
Material and method: Eleven hospitals from the "International Collaborative Donor Project" were selected, 3 in Spain, 5 in Mexico, 2 in Cuba and one in Costa Rica. A random sample was stratified by the type of service and job category. Attitude toward donation and transplantation was assessed using a validated survey. The questionnaire was completed anonymously and was self-administered.
Statistical analysis: Student's t-test, the χ2 test and logistic regression analysis.
Results: Of the 2,785 workers surveyed, 822 were from Spain, 1,595 from Mexico, 202 from Cuba and 166 from Costa Rica and 79% (n=2,191) were in favor of deceased organ donation. According to country, 94% (n=189) of Cubans were in favor, compared to 82% (n=1,313) of the Mexicans, 73% (n=121) of the Costa Ricans and 69% (n=568) of the Spanish (P<.001). In the multivariate analysis, the following variables had the most specific weight: 1) originating from Cuba (odds ratio=8.196; P<.001); 2) being a physician (OR= 2.544; P<.001); 3) performing a job related to transplantation (OR = 1.610; P=.005); 4) having discussed the subject of donation and transplantation within the family (OR= 3.690; P<.001); 5) having a partner with a favorable attitude toward donation and transplantation (OR= 3.289; P<.001); 6) a respondent's belief that his or her religion is in favor of donation and transplantation (OR= 3.021; P=.001); 7) not being concerned about the possible mutilation of the body after donation (OR= 2.994; P<.001); 8) the preference for other options apart from burial for treating the body after death (OR= 2.770; P<.001); and 9) acceptance of carrying out an autopsy if one were needed (OR= 2.808; P<.001).
Conclusions: Hospital personnel in Spanish and Latin American healthcare centers had a favorable attitude toward donation, although 21% of respondents were not in favor of donating. This attitude was more favorable among Latin American workers and was very much conditioned by job-related and psychosocial factors.

The familial risk of autism.
Importance: Autism spectrum disorder (ASD) aggregates in families, but the individual risk and to what extent this is caused by genetic factors or shared or nonshared environmental factors remains unresolved.
Objective: To provide estimates of familial aggregation and heritability of ASD.
Design, setting, and participants: A population-based cohort including 2,049,973 Swedish children born 1982 through 2006. We identified 37,570 twin pairs, 2,642,064 full sibling pairs, 432,281 maternal and 445,531 paternal half sibling pairs, and 5,799,875 cousin pairs. Diagnoses of ASD to December 31, 2009 were ascertained.
Main outcomes and measures: The relative recurrence risk (RRR) measures familial aggregation of disease. The RRR is the relative risk of autism in a participant with a sibling or cousin who has the diagnosis (exposed) compared with the risk in a participant with no diagnosed family member (unexposed). We calculated RRR for both ASD and autistic disorder adjusting for age, birth year, sex, parental psychiatric history, and parental age. We estimated how much of the probability of developing ASD can be related to genetic (additive and dominant) and environmental (shared and nonshared) factors.
Results: In the sample, 14,516 children were diagnosed with ASD, of whom 5689 had autistic disorder. The RRR and rate per 100,000 person-years for ASD among monozygotic twins was estimated to be 153.0 (95% CI, 56.7-412.8; rate, 6274 for exposed vs 27 for unexposed ); for dizygotic twins, 8.2 (95% CI, 3.7-18.1; rate, 805 for exposed vs 55 for unexposed); for full siblings, 10.3 (95% CI, 9.4-11.3; rate, 829 for exposed vs 49 for unexposed); for maternal half siblings, 3.3 (95% CI, 2.6-4.2; rate, 492 for exposed vs 94 for unexposed); for paternal half siblings, 2.9 (95% CI, 2.2-3.7; rate, 371 for exposed vs 85 for unexposed); and for cousins, 2.0 (95% CI, 1.8-2.2; rate, 155 for exposed vs 49 for unexposed). The RRR pattern was similar for autistic disorder but of slightly higher magnitude. We found support for a disease etiology including only additive genetic and nonshared environmental effects. The ASD heritability was estimated to be 0.50 (95% CI, 0.45-0.56) and the autistic disorder heritability was estimated to 0.54 (95% CI, 0.44-0.64).
Conclusions and relevance: Among children born in Sweden, the individual risk of ASD and autistic disorder increased with increasing genetic relatedness. Heritability of ASD and autistic disorder were estimated to be approximately 50%. These findings may inform the counseling of families with affected children.

(2014)MEDLINE-indexed journal, not yet read by usLancet (London, England) · cohort or longitudinal International standards for fetal growth based on serial ultrasound measurements: the Fetal Growth Longitudinal Study of the INTERGROWTH-21st Project.
Background: In 2006, WHO produced international growth standards for infants and children up to age 5 years on the basis of recommendations from a WHO expert committee. Using the same methods and conceptual approach, the Fetal Growth Longitudinal Study (FGLS), part of the INTERGROWTH-21(st) Project, aimed to develop international growth and size standards for fetuses.
Methods: The multicentre, population-based FGLS assessed fetal growth in geographically defined urban populations in eight countries, in which most of the health and nutritional needs of mothers were met and adequate antenatal care was provided. We used ultrasound to take fetal anthropometric measurements prospectively from 14 weeks and 0 days of gestation until birth in a cohort of women with adequate health and nutritional status who were at low risk of intrauterine growth restriction. All women had a reliable estimate of gestational age confirmed by ultrasound measurement of fetal crown-rump length in the first trimester. The five primary ultrasound measures of fetal growth--head circumference, biparietal diameter, occipitofrontal diameter, abdominal circumference, and femur length--were obtained every 5 weeks (within 1 week either side) from 14 weeks to 42 weeks of gestation. The best fitting curves for the five measures were selected using second-degree fractional polynomials and further modelled in a multilevel framework to account for the longitudinal design of the study.
Findings: We screened 13,108 women commencing antenatal care at less than 14 weeks and 0 days of gestation, of whom 4607 (35%) were eligible. 4321 (94%) eligible women had pregnancies without major complications and delivered live singletons without congenital malformations (the analysis population). We documented very low maternal and perinatal mortality and morbidity, confirming that the participants were at low risk of adverse outcomes. For each of the five fetal growth measures, the mean differences between the observed and smoothed centiles for the 3rd, 50th, and 97th centiles, respectively, were small: 2·25 mm (SD 3·0), 0·02 mm (3·0), and -2·69 mm (3·2) for head circumference; 0·83 mm (0·9), -0·05 mm (0·8), and -0·84 mm (1·0) for biparietal diameter; 0·63 mm (1·2), 0·04 mm (1·1), and -1·05 mm (1·3) for occipitofrontal diameter; 2·99 mm (3·1), 0·25 mm (3·2), and -4·22 mm (3·7) for abdominal circumference; and 0·62 mm (0·8), 0·03 mm (0·8), and -0·65 mm (0·8) for femur length. We calculated the 3rd, 5th 10th, 50th, 90th, 95th and 97th centile curves according to gestational age for these ultrasound measures, representing the international standards for fetal growth.
Interpretation: We recommend these international fetal growth standards for the clinical interpretation of routinely taken ultrasound measurements and for comparisons across populations.

Internet-Delivered Interventions for Depression and Anxiety Symptoms in Children and Young People: Systematic Review and Meta-analysis.
Background: Mental health difficulties in children and adolescents are highly prevalent; however, only a minority receive adequate mental health care. Internet-delivered interventions offer a promising opportunity to increase access to mental health treatment. Research has demonstrated their effectiveness as a treatment for depression and anxiety in adults. This work provides an up-to-date examination of the available intervention options and their effectiveness for children and young people (CYP).
Objective: In this systematic review and meta-analysis, we aimed to determine the evidence available for the effectiveness of internet-delivered interventions for treating anxiety and depression in CYP.
Methods: Systematic literature searches were conducted throughout November 2020 using PubMed, PsycINFO, and EBSCO academic search complete electronic databases to find outcome trials of internet-delivered interventions treating symptoms of anxiety and/or depression in CYP by being either directly delivered to the CYP or delivered via their parents. Studies were eligible for meta-analysis if they were randomized controlled trials. Risk of bias and publication biases were evaluated, and Hedges g between group effect sizes evaluating intervention effects after treatment were calculated. Meta-analyses used random-effects models as per protocol.
Results: A total of 23 studies met the eligibility criteria for the systematic review, of which 16 were included in the meta-analyses, including 977 participants in internet-delivered treatment conditions and 1008 participants in control conditions across 21 comparisons. Random-effects models detected a significant small effect for anxiety symptoms (across 20 comparisons; Hedges g=-0.25, 95% CI -0.38 to -0.12; P<.001) and a small but not significant effect for depression (across 13 comparisons; Hedges g=-0.27, 95% CI -0.55 to 0.01; P=.06) in favor of internet-delivered interventions compared with control groups. Regarding secondary outcomes, there was a small effect of treatment across 9 comparisons for impaired functioning (Hedges g=0.52, 95% CI 0.24-0.80; P<.001), and 5 comparisons of quality of life showed no effect (Hedges g=-0.01, 95% CI -0.23 to 0.21; P=.94).
Conclusions: The results show that the potential of internet-delivered interventions for young people with symptoms of anxiety or depression has not been tapped into to date. This review highlights an opportunity for the development of population-specific interventions and their research to expand our current knowledge and build an empirical base for digital interventions for CYP.

Go Where the Students Are: A Comparison of the Use of Social Networking Sites Between Medical Students and Medical Educators.
Background: Medical education has grown beyond the boundaries of the classroom, and social media is seen as the bridge between informal and formal learning as it keeps students highly engaged with educational content outside the classroom.
Objective: The purpose of this study is to explore the perceptions of medical educators and medical students regarding the use of social media for educational purposes.
Methods: Both groups (medical educators and students) were invited to take a survey. The surveys consisted of 29 questions, including Likert-style, multiple choice, yes/no, ranking, and short answer questions. The survey forms and statistics were built using Google Drive analytics with the free Spanning Stats module. To compare between professors and students, results were exported to a Microsoft Office Excel spreadsheet (Microsoft Corp, Redmond, WA). The study protocol was approved by The Ottawa Health Science Network Research Ethics Board (OHSN-REB:20140680-01H).
Results: The overall response rate to the survey was 40.9% (63/154) for students, and 36% (72/200) for medical educators. The majority of educators (79%, 57/72) and students (100.0%, 63/63) had presence on social networking sites (SNSs). Only (33% 19/57) of educators used SNSs with their students, the most used sites were Facebook (52%, 10/19) and Twitter (47%, 9/19), followed by LinkedIn (21%, 4/19), Google+ (16%, 3/19),YouTube (11%, 2/19), and blogs (11%, 2/19). Facebook (100%, 63/63), YouTube (43%, 27/63), Twitter (31%, 20/63), and Instagram (30%, 19/63) were the sites most commonly used by students. The educators used SNSs mainly to post opinions (86%, 49/57), share videos (81%, 46/57), chat (71%, 41/57), engage in medical education (68%, 40/57), take surveys (24%, 14/57), and play games (5%, 3/57). On the other hand, students used SNSs mainly to chat with friends (94%, 59/63), for medical education purposes (67%, 42/63), to share videos (62%, 39/63), to post opinions (49%, 31/63), to take surveys (11%, 7/63), and to play games (6%, 4/63). Most educators (67%, 38/57) do not use social media in their education Although most of the educators (89%, 17/19) and students (73%, 46/63) found the use of social media time-effective, that it offered an inviting atmosphere (89%, 17/19 and 70%, 44/63), and that it enhanced the learning experience (95%, 18/19 and 70%, 44/63), both groups stated that they had colleagues who refused to use social media. The detractors' concerns included privacy issues (47%, 18/38), time-wasting (34%, 13/38), distraction (21%, 8/38), and that these media might not be suitable for education (11%, 4/38). When it came to using SNSs with the students, the educators most often used SNSs to post articles (42%, 8/19), explanatory comments (31%, 6/19), and videos (27%, 5/19).While students preferred the following posts : Quizzes (87% 55/63), revision files (82% 52/63) and explanatory comments (29% 21/63).
Conclusions: Although social media continue to grow, some educators find that they do not offer suitable modes of learning. However, it is important to acknowledge that there are persistent differences in technology adoption and use along gender, racial, and socioeconomic lines; this is often referred to as the "digital divide". The current study shows that students prefer certain posts like quizzes and revision files, while educators are focused on posting videos, articles, and explanatory comments. Medical educators are encouraged to focus on the students in a way to minimize the gap between learners and educators. It will remain our responsibility as educators to focuson the student, use SNSs at their fullest, and integrate them into traditional Web-based management systems and into existingcurricula to best benefit the students.

(2022)MEDLINE-indexed journal, not yet read by usPloS one The cross-sectional association of stressful life events with depression severity among patients with hypertension and diabetes in Malawi.
Depressive disorders are a leading cause of global morbidity and remain disproportionately high in low- and middle-income settings. Stressful life events (SLEs) are known risk factors for depressive episodes and worsened depressive severity, yet are under-researched in comparison to other depression risk factors. As depression is often comorbid with hypertension, diabetes, and other noncommunicable diseases (NCDs), research into this relationship among patients with NCDs is particularly relevant to increasing opportunities for integrated depression and NCD care. This study aims to estimate the cross-sectional association between SLEs in the three months preceding baseline interviews and baseline depressive severity among patients with at least mild depressive symptoms who are seeking NCD care at 10 NCD clinics across Malawi. SLEs were measured by the Life Events Survey and depressive severity (mild vs. moderate to severe) was measured by the Patient Health Questionnaire-9. The study population (n = 708) was predominately currently employed, grand multiparous (5-8 children) women with a primary education level. Two thirds (63%) had mild depression while 26%, 8%, and 3% had moderate, moderately severe, and severe depression, respectively. Nearly all participants (94%) reported at least one recent SLE, with the most common reported SLEs being financial stress (48%), relationship changes (45%), death of a family member or friend (41%), or serious illness of a family member or friend (39%). Divorce/separation, estrangement from a family member, losing source of income, and major new health problems were significant predictors of greater (moderate or severe) depressive severity compared to mild severity. Having a major new health problem or experiencing divorce/separation resulted in particularly high risk of more severe depression. After adjustment, each additional SLE was associated with a 9% increased risk of moderate or worse depressive severity compared to mild depressive severity (RR: 1.09; (95% CI: 1.05, 1.13), p<0.0001). Among patients with NCDs with at least mild depressive symptoms, SLEs in the prior 3 months were associated with greater depressive severity. While many SLEs may not be preventable, this research suggests that assessment of SLEs and teaching of positive coping strategies when experiencing SLEs may play an important role in integrated NCD and depression treatment models.

Feasibility, Acceptability, and Preliminary Efficacy of a Positive Affect Skills Intervention for Adults With Fibromyalgia.
Background and objectives: To examine the feasibility, acceptability, and preliminary efficacy of a positive affect skills intervention for middle-aged and older adults with fibromyalgia syndrome (FMS).
Research design and methods: Ninety-five participants with FMS aged 50 and older (94% female) were randomized to 1 of 2 conditions: (a) Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR; n = 49) or (b) emotion reporting/control (n = 46). LARKSPUR included 5 weeks of skill training that targeted 8 skills to help foster positive affect, including (a) noticing positive events, (b) savoring positive events, (c) identifying personal strengths, (d) behavioral activation to set and work toward attainable goals, (e) mindfulness, (f) positive reappraisal, (g) gratitude, and (h) acts of kindness. Outcome data were collected via online surveys at baseline, postintervention, and 1-month follow-up.
Results: Completion rates (88%) and satisfaction ratings (10-point scale) were high (LARKSPUR: M = 9.14, standard deviation (SD) = 1.49; control: M = 8.59, SD = 1.97). Improvements were greater in LARKSPUR participants compared with control participants on measures of positive affect (Cohen's d = 0.19 [0.15, 0.24]), negative affect (Cohen's d = -0.07 [-0.11, -0.02]), and pain catastrophizing (Cohen's d = -0.14 [-0.23, -0.05]). Improvements in positive affect (Cohen's d = 0.17 [0.13, 0.22]) and negative affect (Cohen's d = -0.11 [-0.15, -0.06]) were maintained at 1-month follow-up. Dose-response analyses indicated that intervention engagement significantly predicted pre-to-post and post-to-follow-up reductions in pain catastrophizing.
Discussion and implications: The current preliminary findings add to existing literature and highlight the specific potential of internet-delivered positive affect skills programs for adults with FMS.

Domestic violence in pregnancy: prevalence and characteristics of the pregnant woman.
Aims and objectives: To determine the prevalence of domestic violence (physical, psychological or sexual) during pregnancy and to characterise these women.
Background: Pregnant women are not immune to domestic violence and therefore may be subject to any form of physical, psychological or sexual violence by partners. Health professionals' knowledge and awareness are important in the identification and intervention of pregnant women who experience domestic violence.
Methods: Quantitative, descriptive, correlational study, using a nonprobabilistic convenience sample consisting of a total of 852 postpartum women, of whom 370 were experiencing domestic violence according to the criteria adopted through the modified scale of prevalence, applied between February-June 2012 in two Portuguese public health institutions. Authorisation was given by the Ethics Committees/Administration Councils of both institutions involved and the National Committee of Data Protection.
Results: The prevalence of DV during pregnancy was 43·4% (physical violence - 21·9%; psychological violence - 43·2%; and sexual violence - 19·6%). These women had the following profile: immigrant (OR = 5·70; IC95% 3·32-9·78), non-Caucasian (OR = 6·27; IC95% 3·76-10·46), single/divorced/widowed (OR = 2·28; IC95% 1·70-3·05), academic qualifications up to year 9 (OR = 4·94; IC95% 3·31-7·37); between 10-12 years of schooling (OR = 2·36; IC95% 1·70-3·29); unemployed (OR = 2·01; IC95% 1·50-2·69); and with a monthly income <1000 euros (OR = 1·90; IC95% 1·44-2·50). Through logistic regression, the following protective factors have been identified: nationality (Portuguese), race (Caucasian) and place of residence (city).
Conclusions: Almost half of the sample had experienced some form of domestic violence. This is associated with certain sociodemographic factors identified in the study. Psychological violence was the most prevalent during pregnancy.
Relevance to clinical practice: Knowledge of the prevalence and characteristics of pregnant women who experience domestic violence is of paramount importance in planning appropriate strategies for their needs during pregnancy. Results indicate the need for nurses to intervene when warning signs of domestic violence against pregnant women are detected.

Association of neighbourhood migrant density and risk of non-affective psychosis: a national, longitudinal cohort study.
Background: Elevated risk of psychotic disorders in migrant groups is a public mental health priority. We investigated whether living in areas of high own-region migrant density was associated with reduced risk of psychotic disorders among migrants and their children, and whether generation status, probable visible minority status, or region-of-origin affected this relationship.
Methods: We used the Swedish registers to identify migrants and their children born between Jan 1, 1982, and Dec 31, 1996, and living in Sweden on or after their 15th birthday. We tracked all included participants from age 15 years or date of migration until emigration, death, or study end (Dec 31, 2016). The outcome was an ICD-10 diagnosis of non-affective psychosis (F20-29). We calculated own-region and generation-specific own-region density within the 9208 small areas for market statistics neighbourhoods in Sweden, and estimated the relationship between density and diagnosis of non-affective psychotic disorders using multilevel Cox proportional hazards models, adjusting for individual confounders (generation status, age, sex, calendar year, lone dwelling, and time since migration [migrants only]), family confounders (family income, family unemployment, and social welfare), and neighbourhood confounders (deprivation index, population density, and proportion of lone dwellings), and using the Akaike information criterion (AIC) to compare model fit.
Findings: Of 468 223 individuals included in the final cohort, 4582 (1·0%) had non-affective psychotic disorder. Lower own-region migrant density was associated with increased risk of psychotic disorders among migrants (hazard ratio [HR] 1·05, 95% CI 1·02-1·07 per 5% decrease) and children of migrants (1·03, 1·01-1·06), after adjustment. These effects were stronger for probable visible minority migrants (1·07, 1·04-1·11), including migrants from Asia (1·42, 1·15-1·76) and sub-Saharan Africa (1·28, 1·15-1·44), but not migrants from probable non-visible minority backgrounds (0·99, 0·94-1·04). Among migrants, adding generation status to the measure of own-region density provided a better fit to the data than overall own-region migrant density (AIC 36 103 vs 36 106, respectively), with a 5% decrease in generation-specific migrant density corresponding to a HR of 1·07 (1·04-1·11).
Interpretation: Migrant density was associated with non-affective psychosis risk in migrants and their children. Stronger protective effects of migrant density were found for probable visible minority migrants and migrants from Asia and sub-Saharan Africa. For migrants, this risk intersected with generation status. Together, these results suggest that this health inequality is socially constructed.

Prevalence and Nature of Sexist and Racial/Ethnic Microaggressions Against Surgeons and Anesthesiologists.
Importance: Workplace mistreatment can manifest as microaggressions that cause chronic, severe distress. As physician burnout becomes a global crisis, quantitative research to delineate the impact of microaggressions is imperative.
Objectives: To examine the prevalence and nature of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists and assess the association with physician burnout.
Design, setting, and participants: This cross-sectional survey evaluated microaggressions and physician burnout within a diverse cohort of surgeons and anesthesiologists in a large health maintenance organization. A total of 1643 eligible participants were sent a recruitment email on January 8, 2020, 1609 received the email, and 652 replied, for a response rate of 41%. The study survey remained open until February 20, 2020. A total of 588 individuals (37%) were included in the study after exclusion criteria were applied.
Exposures: The Maslach Burnout Inventory, the Racial Microaggression Scale, and the Sexist Microaggression Experience and Stress Scale.
Main outcomes and measures: The primary outcomes were prevalence and nature of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists using the Sexist Microaggression Experience and Stress Scale and Racial Microaggression Scale. Secondary outcomes were frequency and severity of microaggressions, prevalence of physician burnout, and associations between microaggressions and physician burnout.
Results: Data obtained from 588 respondents (249 [44%] female, 367 [62%] racial/ethnic minority, 224 [38.1%] 40-49 years of age) were analyzed. A total of 245 of 259 female respondents (94%) experienced sexist microaggressions, most commonly overhearing or seeing degrading female terms or images. Racial/ethnic microaggressions were experienced by 299 of 367 racial/ethnic-minority physicians (81%), most commonly reporting few leaders or coworkers of the same race/ethnicity. Criminality was rare (18 of 367 [5%]) but unique to and significantly higher for Hispanic and Black physicians. Individuals who identified as underrepresented minorities were more likely to experience environmental inequities (odds ratio [OR], 4.21; 95% CI, 1.6-10.75; P = .002) and criminality (OR, 14.93; 95% CI, 4.5-48.5; P < .001). The prevalence of physician burnout was 47% (280 of 588 physicians) and higher among female physicians (OR, 1.60; 95% CI, 1.03-2.47; P = .04) and racial/ethnic-minority physicians (OR, 2.08; 95% CI, 1.31-3.30; P = .002). Female physicians who experienced sexist microaggressions (racial/ethnic-minority female physicians: OR, 1.84; 95% CI, 1.04-3.25; P = .04; White female physicians: OR, 1.99; 95% CI, 1.07-3.69; P = .03) were more likely to experience burnout. Racial/ethnic-minority female physicians (OR, 1.86; 95% CI, 1.03-3.35; P = .04) who experienced racial microaggressions were more likely to report burnout. Racial/ethnic-minority female physicians who had the compound experience of sexist and racial/ethnic microaggressions (OR, 2.05; 95% CI, 1.14-3.69; P = .02) were more likely to experience burnout.
Conclusions and relevance: The prevalence of sexist and racial/ethnic microaggressions against female and racial/ethnic-minority surgeons and anesthesiologists was high and associated with physician burnout. This study provides a valuable response to the increasing call for evidence-based data on surgical workplace mistreatment.

(2021)MEDLINE-indexed journal, not yet read by usEnvironment international A planetary health model for reducing exposure to faecal contamination in urban informal settlements: Baseline findings from Makassar, Indonesia.
Background: The intense interactions between people, animals and environmental systems in urban informal settlements compromise human and environmental health. Inadequate water and sanitation services, compounded by exposure to flooding and climate change risks, expose inhabitants to environmental contamination causing poor health and wellbeing and degrading ecosystems. However, the exact nature and full scope of risks and exposure pathways between human health and the environment in informal settlements are uncertain. Existing models are limited to microbiological linkages related to faecal-oral exposures at the individual level, and do not account for a broader range of human-environmental variables and interactions that affect population health and wellbeing.
Methods: We undertook a 12-month health and environmental assessment in 12 flood-prone informal settlements in Makassar, Indonesia. We obtained caregiver-reported health data, anthropometric measurements, stool and blood samples from children < 5 years, and health and wellbeing data for children 5-14 years and adult respondents. We collected environmental data including temperature, mosquito and rat species abundance, and water and sediment samples. Demographic, built environment and household asset data were also collected. We combined our data with existing literature to generate a novel planetary health model of health and environment in informal settlements.
Results: Across the 12 settlements, 593 households and 2764 participants were enrolled. Two-thirds (64·1%) of all houses (26·3-82·7% per settlement) had formal land tenure documentation. Cough, fever and diarrhoea in the week prior to the survey were reported among an average of 34.3%, 26.9% and 9.7% of children aged < 5 years, respectively; although proportions varied over time, prevalence among these youngest children was consistently higher than among children 5-14 years or adult respondents. Among children < 5 years, 44·3% experienced stunting, 41·1% underweight, 12.4% wasting, and 26.5% were anaemic. There was self- or carer-reported poor mental health among 16.6% of children aged 5-14 years and 13.9% of adult respondents. Rates of potential risky exposures from swimming in waterways, eating uncooked produce, and eating soil or dirt were high, as were exposures to flooding and livestock. Just over one third of households (35.3%) had access to municipal water, and contamination of well water with E. coli and nitrogen species was common. Most (79·5%) houses had an in-house toilet, but no houses were connected to a piped sewer network or safe, properly constructed septic tank. Median monthly settlement outdoor temperatures ranged from 26·2 °C to 29.3 °C, and were on average, 1·1 °C warmer inside houses than outside. Mosquito density varied over time, with Culex quinquefasciatus accounting for 94·7% of species. Framed by a planetary health lens, our model includes four thematic domains: (1) the physical/built environment; (2) the ecological environment; (3) human health; and (4) socio-economic wellbeing, and is structured at individual, household, settlement, and city/beyond spatial scales.
Conclusions: Our planetary health model includes key risk factors and faecal-oral exposure pathways but extends beyond conventional microbiological faecal-oral enteropathogen exposure pathways to comprehensively account for a wider range of variables affecting health in urban informal settlements. It includes broader ecological interconnections and planetary health-related variables at the household, settlement and city levels. It proposes a composite framework of markers to assess water and sanitation challenges and flood risks in urban informal settlements for optimal design and monitoring of interventions.

Psychiatry Prevalence of post-traumatic stress disorder and common mental disorders in health-care workers in England during the COVID-19 pandemic: a two-phase cross-sectional study.
Background: Previous studies on the impact of the COVID-19 pandemic on the mental health of health-care workers have relied on self-reported screening measures to estimate the point prevalence of common mental disorders. Screening measures, which are designed to be sensitive, have low positive predictive value and often overestimate prevalence. We aimed to estimate prevalence of common mental disorders and post-traumatic stress disorder (PTSD) among health-care workers in England using diagnostic interviews.
Methods: We did a two-phase, cross-sectional study comprising diagnostic interviews within a larger multisite longitudinal cohort of health-care workers (National Health Service [NHS] CHECK; n=23 462) during the COVID-19 pandemic. In the first phase, health-care workers across 18 NHS England Trusts were recruited. Baseline assessments were done using online surveys between April 24, 2020, and Jan 15, 2021. In the second phase, we selected a proportion of participants who had responded to the surveys and conducted diagnostic interviews to establish the prevalence of mental disorders. The recruitment period for the diagnostic interviews was between March 1, 2021 and Aug 27, 2021. Participants were screened with the 12-item General Health Questionnaire (GHQ-12) and assessed with the Clinical Interview Schedule-Revised (CIS-R) for common mental disorders or were screened with the 6-item Post-Traumatic Stress Disorder Checklist (PCL-6) and assessed with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) for PTSD.
Findings: The screening sample contained 23 462 participants: 2079 participants were excluded due to missing values on the GHQ-12 and 11 147 participants due to missing values on the PCL-6. 243 individuals participated in diagnostic interviews for common mental disorders (CIS-R; mean age 42 years [range 21-70]; 185 [76%] women and 58 [24%] men) and 94 individuals participated in diagnostic interviews for PTSD (CAPS-5; mean age 44 years [23-62]; 79 [84%] women and 15 [16%] men). 202 (83%) of 243 individuals in the common mental disorders sample and 83 (88%) of 94 individuals in the PTSD sample were White. GHQ-12 screening caseness for common mental disorders was 52·8% (95% CI 51·7-53·8). Using CIS-R diagnostic interviews, the estimated population prevalence of generalised anxiety disorder was 14·3% (10·4-19·2), population prevalence of depression was 13·7% (10·1-18·3), and combined population prevalence of generalised anxiety disorder and depression was 21·5% (16·9-26·8). PCL-6 screening caseness for PTSD was 25·4% (24·3-26·5). Using CAPS-5 diagnostic interviews, the estimated population prevalence of PTSD was 7·9% (4·0-15·1).
Interpretation: The prevalence estimates of common mental disorders and PTSD in health-care workers were considerably lower when assessed using diagnostic interviews compared with screening tools. 21·5% of health-care workers met the threshold for diagnosable mental disorders, and thus might benefit from clinical intervention.

Conrad N, Judge A, Tran J, Mohseni H, Hedgecott D, Crespillo AP, Allison M, Hemingway H, Cleland JG, McMurray JJV, Rahimi K. (2018)MEDLINE-indexed journal, not yet read by usLancet (London, England) Temporal trends and patterns in heart failure incidence: a population-based study of 4 million individuals.
Background: Large-scale and contemporary population-based studies of heart failure incidence are needed to inform resource planning and research prioritisation but current evidence is scarce. We aimed to assess temporal trends in incidence and prevalence of heart failure in a large general population cohort from the UK, between 2002 and 2014.
Methods: For this population-based study, we used linked primary and secondary electronic health records of 4 million individuals from the Clinical Practice Research Datalink (CPRD), a cohort that is representative of the UK population in terms of age and sex. Eligible patients were aged 16 years and older, had contributed data between Jan 1, 2002, and Dec 31, 2014, had an acceptable record according to CPRD quality control, were approved for CPRD and Hospital Episodes Statistics linkage, and were registered with their general practice for at least 12 months. For patients with incident heart failure, we extracted the most recent measurement of baseline characteristics (within 2 years of diagnosis) from electronic health records, as well as information about comorbidities, socioeconomic status, ethnicity, and region. We calculated standardised rates by applying direct age and sex standardisation to the 2013 European Standard Population, and we inferred crude rates by applying year-specific, age-specific, and sex-specific incidence to UK census mid-year population estimates. We assumed no heart failure for patients aged 15 years or younger and report total incidence and prevalence for all ages (>0 years).
Findings: From 2002 to 2014, heart failure incidence (standardised by age and sex) decreased, similarly for men and women, by 7% (from 358 to 332 per 100 000 person-years; adjusted incidence ratio 0·93, 95% CI 0·91-0·94). However, the estimated absolute number of individuals with newly diagnosed heart failure in the UK increased by 12% (from 170 727 in 2002 to 190 798 in 2014), largely due to an increase in population size and age. The estimated absolute number of prevalent heart failure cases in the UK increased even more, by 23% (from 750 127 to 920 616). Over the study period, patient age and multi-morbidity at first presentation of heart failure increased (mean age 76·5 years [SD 12·0] to 77·0 years [12·9], adjusted difference 0·79 years, 95% CI 0·37-1·20; mean number of comorbidities 3·4 [SD 1·9] vs 5·4 [2·5]; adjusted difference 2·0, 95% CI 1·9-2·1). Socioeconomically deprived individuals were more likely to develop heart failure than were affluent individuals (incidence rate ratio 1·61, 95% CI 1·58-1·64), and did so earlier in life than those from the most affluent group (adjusted difference -3·51 years, 95% CI -3·77 to -3·25). From 2002 to 2014, the socioeconomic gradient in age at first presentation with heart failure widened. Socioeconomically deprived individuals also had more comorbidities, despite their younger age.
Interpretation: Despite a moderate decline in standardised incidence of heart failure, the burden of heart failure in the UK is increasing, and is now similar to the four most common causes of cancer combined. The observed socioeconomic disparities in disease incidence and age at onset within the same nation point to a potentially preventable nature of heart failure that still needs to be tackled.

Psychological responses, mental health, and sense of agency for the dual challenges of climate change and the COVID-19 pandemic in young people in the UK: an online survey study.
Background: The COVID-19 pandemic and climate change are both significant and pressing global challenges, posing threats to public health and wellbeing. Young people are particularly vulnerable to the distress both crises can cause, but understanding of the varied psychological responses to both issues is poor. We aimed to investigate these responses and their links with mental health conditions and feelings of agency.
Methods: We conducted an online survey between Aug 5 and Oct 26, 2020, targeting a diverse sample of young people (aged 16-24 years, n=530) in the UK. The survey was distributed using a combination of a survey panel (panel sample) and direct approaches to youth groups and schools who shared the survey with young people in their networks (community sample). We collected data on respondents' psychological responses to both climate change and the COVID-19 pandemic, their sense of agency to respond to each crisis, and the range of impacts on their lives. We also collected demographics data and screened for mental health and wellbeing indicators. We used non-parametric tests for most statistical comparisons. For paired samples, we used Wilcoxon's signed-rank test, and used Mann-Whitney U-tests or Kruskal-Wallis tests for two or more independent samples. Summed scale scores were considered as interval-level data and analysed with Student's t tests and ANOVAs. Effect sizes are reported as Cohen's d and partial eta-squared (η·2p), respectively.
Findings: After excluding 18 suspected bots and 94 incomplete responses, 530 responses were retained for analysis. Of the 518 respondents who provided demographic data, 63% were female, 71·4% were White, and the mean family affluence score was 8·22 (SD 2·29). Most participants (n=343; 70%) did not report a history of diagnosis or treatment for a mental health disorder, but mental health scores indicated a common experience of (relatively mild) symptoms of anxiety, depression, and stress. Although UK youth reported more life disruption and concern for their future due to the COVID-19 pandemic, climate change was associated with significantly greater distress overall, particularly for individuals with low levels of generalised anxiety. The COVID-19 pandemic was more associated with feelings of anxiety, isolation, disconnection, and frustration; distress around loss and grief; and effects on quality of life. Climate change was more likely to evoke emotions such as interest and engagement, guilt, shame, anger, and disgust. The greater distress attributed to climate change overall was due, in particular, to higher levels of guilt, sense of personal responsibility, and greater distress triggered by upsetting media coverage. Agency to address climate change was associated with greater climate distress, but pandemic-related distress and agency were unrelated.
Interpretation: The COVID-19 pandemic and climate change are affecting the wellbeing of UK young people in distinct ways, with implications for health service, policy, and research responses. There is a need for mental health practitioners, policy makers, and other societal actors to account for the complex relationship between climate agency, distress, and mental wellbeing in young people.

Residential greenness and prevalence of major depressive disorders: a cross-sectional, observational, associational study of 94 879 adult UK Biobank participants.
Background: Increased urbanisation and the associated reduced contact of individuals with natural environments have led to a rise in mental disorders, including depression. Residential greenness, a fundamental component of urban design, has been shown to reduce the public health burden of mental disorders. The present study investigates the association between residential green exposure and prevalence of major depressive disorders using a large and diverse cross-sectional dataset from the UK Biobank.
Methods: In this cross-sectional, observational, associational study, we used baseline data from the UK Biobank cohort of participants aged 37-73 years from across the UK. Environmental exposure data were derived from a modelled and linked built environment database. Residential greenness was assessed with a 0·5 m resolution Normalised Difference Vegetation Index, which is derived from spectral reflectance measurements in remotely sensed colour infrared data and measured within geocoded dwelling catchments. Other environment metrics included street-level movement density, terrain, and fine particulate exposures. A series of logistic models examined associations between residential greenness and odds of major depressive disorder after adjusting for activity-influencing environments and individual covariates.
Findings: Of 122 993 participants with data on major depressive disorder, the study analytical sample comprised 94 879 (77·1%) participants recruited across ten UK Biobank assessment centres between April 29, 2009, and Oct 1, 2010. A protective effect of greenness on depression was consistently observed, with 4·0% lower odds of major depressive disorder per interquartile increment in Normalised Difference Vegetation Index greenness (odds ratio 0·960, 95% CI 0·93-0·99; p=0·0044). Interaction analyses indicated that the beneficial effects of greenness were more pronounced among women, participants younger than 60 years, and participants residing in areas with low neighbourhood socioeconomic status or high urbanicity.
Interpretation: The results point to the benefits of well designed green environments on mental health. Further longitudinal studies are needed to decipher causal pathways. In the UK, policies aimed at optimising allocation and design of green spaces might help preserve psychological ecosystem services, thereby, improving the mental wellbeing of populations and enhancing the mental capital of cities.

Suffering in silence: Stigma, healthcare barriers, and resilience during Sierra Leone's 2025 clade IIb mpox outbreak-A multi-perspective qualitative study.
Mpox was confirmed in Sierra Leone in January 2025, with a public health emergency declared shortly thereafter. By June 2025, the country reported over 4,000 confirmed cases caused by clade IIb. Limited qualitative research has explored the lived experiences of affected populations during mpox outbreaks in African settings. This study explored multi-stakeholder experiences of mpox, including illness trajectories, stigma manifestations, healthcare-seeking behaviours, and health system response challenges. We conducted a multi-perspective qualitative study using thematic framework analysis between March and August 2025 across four districts. Participants included mpox survivors (n = 42), healthcare workers (n = 38), community members (n = 36), and contact tracers (n = 24). Data were collected through 94 semi-structured interviews and 12 focus group discussions. Analysis was guided by a modified Social Ecological Model (SEM) integrating the Health Stigma and Discrimination Framework (HSDF). Five interconnected themes emerged: (1) illness characterised by physical suffering and lasting bodily changes; (2) multi-layered stigma operating across individual, interpersonal, community, and institutional levels; (3) healthcare-seeking shaped by fear of disclosure and economic constraints; (4) healthcare workers' moral distress and professional isolation; (5) adaptive health system response alongside coordination challenges. Stigma operated as a cross-cutting dimension that intersected with all other themes, shaping illness experience, care-seeking behaviour, professional practice, and system-level response simultaneously. It also permeated all dimensions of the mpox outbreak experience, delaying care-seeking, undermining contact tracing, and compounding healthcare worker distress. Compound trauma from sequential epidemic exposure emerged as a distinct burden among frontline workers. These findings point to the need for stigma-informed outbreak response strategies, sustained healthcare worker support mechanisms, and community-centred communication approaches in post-conflict, resource-constrained settings facing recurrent epidemics.

Cohort Profile: The National Longitudinal Study of Adolescent to Adult Health (Add Health)
The National Longitudinal Study of Adolescent Health (Add Health) was developed in the 1990s in response to a mandate from the United States Congress to fund a study of adolescent health, and was designed by a team of multidisciplinary investigators from the social, behavioural and biomedical sciences. The original purpose of Add Health was to understand the causes of adolescent health and health behaviour, with special emphasis on the multiple contexts of adolescent life. To achieve this scientific goal, Add Health sampled the school and family environments in which young people live their lives, which included data on peer relationship dyads, parents, siblings, neighbourhoods and communities, and provides independent and direct measurement of these complex environments over time. As the cohort transitioned into adulthood, research objectives turned to understanding how adolescent experiences, behaviours and contexts are linked to health and achievement outcomes in adulthood, and the name of the study was officially changed to The National Longitudinal Study of Adolescent to Adult Health in 2014. Add Health is housed at the Carolina Population Center at the University of North Carolina (UNC) and has been led by two principal investigators and project directors: J Richard Udry from 1994–2004; and Kathleen Mullan Harris from 2004 to the present. Add Health is a nationally representative cohort study of more than 20 000 adolescents in grades 7–12 (aged 12–19) in the USA in 1994–95, who have been followed through adolescence and into adulthood with five in-home interviews in 1995 (Wave I), 1996 (Wave II), 2001–02 (Wave III), 2008–09 (Wave IV) and 2016–18 (Wave V).1Figure 1 displays the sampling design for selecting the original cohort. A school-based design selected 80 high schools and a paired feeder school from a list of all high schools in the USA in 1994. An in-school questionnaire was administered to more than 90 000 students in grades 7–12, who attended these schools during the 1994–95 school year, and school administrators also filled out a questionnaire about the school. Sampling structure. School rosters from the 1993–94 school year provided the sampling frame for a second level of sampling for a 90-min in-home interview with an adolescent and a 30-min interview with one parent. A grade- and gender-stratified core sample was selected from each school pair, representing a self-weighting nationally representative sample of 12 105 American adolescents in grades 7–12 in 1995. Based on responses to the in-school survey, specific subpopulations were oversampled for purposes of providing sufficient numbers for research on vulnerable and otherwise rare populations, including ethnic (Cuban, Puerto Rican and Chinese), genetic relatedness to siblings (identical/fraternal twins, full/half siblings and unrelated adolescents living in the same household), adoption status and disability samples. Black adolescents with highly educated parents were also oversampled. For two large schools and fourteen small schools, interviews with all enrolled students were attempted to create a special saturation sample. The core sample plus the special samples yield a total of 20 745 adolescents. This Wave I in-home sample represents the national cohort of adolescents in grades 7–12 in the USA in 1995, which is followed prospectively. Because school rosters from the year preceding sample selection were used as the sampling frame for the prospective cohort, high school dropouts over 2 years (e.g. 1993–94; 1994–95) were eligible for sample selection, resulting in little bias due to high school dropouts.2 For more details on design, see Harris 2010 and Harris et al., 2013.3,4 Figure 2 shows the longitudinal design of Add Health. The Wave I in-home adolescent cohort has been followed up with four subsequent waves spanning 20+ years. In 1996, all adolescents in grades 7 through 11 in Wave I (plus 12th graders who were part of the genetic and adopted sample) were re-interviewed for Wave II (n = 14 738); the decision not to follow up the seniors who were in grade 12 at Wave I was design-based. The Wave II sample were in grades 8 through 12. A follow-up school administrator interview measured change in school context from 1995 to 1996. Longitudinal design. The original cohort was followed through their transition to early adulthood with a Wave III in-home interview in 2001–02 when the sample was aged 18–26 years (n = 15 197). A sample of 1507 partners were randomly selected during the in-home interview and interviewed, filling quota samples of about 500 married, 500 cohabiting and 500 dating partners. Wave IV re-interviewed the original cohort as they settled into young adulthood in 2008–09 when the cohort was aged 24–32 years (n = 15 701). Wave V followed the cohort to the end of young adulthood when they were aged 32–42, with continuous interviewing using a mixed-mode protocol during 2016–18. Finally, the Add Health Parent Study completed a 20-year follow-up of a subset of the parents of Add Health respondents during 2015–17 (n = 3006). Add Health uses state-of-the-art methods and techniques for panel maintenance and tracing to locate and schedule an interview with all living eligible respondents, including those who may have been non-responsive in a preceding wave. Table 1 presents response rates for the eligible sample at each completed wave of interviews. Response rates have been quite high, highest when the interval between interview waves is short but remarkably high even when the interval is over 5 years at Waves III and IV. The transition from adolescence to early adulthood and the young adult period is an especially transient phase of the life course and it is difficult to track and locate young people. Add Health has done exceptionally well, with response rates of 77.4% and 80.3% at Waves III and IV. Response rates in Add Health for the eligible sample at each wave of in-home interviews By design, respondents who were in the 12th grade at Wave I and who were not part of the genetic sample were not interviewed at Wave II. Response rate at Wave III is based on 15 170 respondents who had data at Wave I. An additional 27 respondents without Wave I data were included at Wave III as part of the genetic subsample. Wave V response rates are not provided because data collection is ongoing, and only a subset of Wave V respondents completed in-home interviews. Response rates in Add Health for the eligible sample at each wave of in-home interviews By design, respondents who were in the 12th grade at Wave I and who were not part of the genetic sample were not interviewed at Wave II. Response rate at Wave III is based on 15 170 respondents who had data at Wave I. An additional 27 respondents without Wave I data were included at Wave III as part of the genetic subsample. Wave V response rates are not provided because data collection is ongoing, and only a subset of Wave V respondents completed in-home interviews. There has been differential attrition by gender, age, socioeconomic status, urban residence, immigrant status and race across time, with higher response rates for female, younger, higher socioeconomic status, urban, native-born and White respondents at Waves III and IV. These attrition patterns are consistent with most longitudinal cohort studies. Add Health response rates exceed other national studies with multiple year intervals between waves (e.g. National Survey of Families and Households 2001–03 wave had a 55% response rate; Midlife in the United States 2004–06 interview had a 75% retention rate).5,6 At each wave, Add Health analysed whether patterns of attrition pose any bias to estimates of survey outcomes.7–10 In general, non-response analyses compare respondents and non-respondents on a range of demographic, health, behavioural and attitudinal indicators measured at baseline, and estimate the extent to which differences between respondents and non-respondents introduce bias in study results. Results indicated that total and relative biases, remaining after study estimates were adjusted with final sampling weights, were minimal and that the sample at each wave adequately represented the same population as the Wave I sample. Analysis of bias due to attrition at Wave IV indicated low rates of bias that rarely exceeded 1%, which is small relative to the 20% to 80% prevalence rates for most of the baseline indicators. Despite common patterns of attrition over time, the design strategy to re-interview the original Wave I cohort at each follow-up wave minimizes non-response bias and continues to adequately represent the original cohort of 7-12th graders in US schools in 1995. Add Health contains unprecedented environmental, behavioural, psychosocial, biological and genetic data from early adolescence into adulthood on a large, nationally representative sample with extensive racial, ethnic, socioeconomic and geographical diversity.4 Longitudinal survey data on respondents’ social, economic, psychological and physical well-being is combined with contextual data on family, neighbourhood, community, school, friendships, peer groups and romantic relationships, providing unique opportunities to study how psychological characteristics, social environments and behaviours beginning in early adolescence are linked to health and well-being in adulthood. Extensive longitudinal life histories of health-related behaviour are available, including physical activity, risk behaviour, substance use, sexual behaviour, civic engagement, education and multiple longitudinal indicators of health status, such as general health, chronic illness, overweight status and obesity, mental health, disability, health promotion and sleep. Objective measures of health were collected across all waves, including anthropometrics, sexually transmitted infection (STI) test results [including human immunodeficiency virus (HIV)], DNA and an expanded set of biomarkers in adulthood (Waves IV and V) (including blood pressure and pulse, measures of glucose homeostasis, lipid metabolism, inflammation, immune and renal function and a medications inventory). Below we describe the innovative multilevel data that have provided unprecedented research opportunities for a multidisciplinary scientific community. The clustered design of Add Health makes possible unique contextual levels of measurement, shown in Table 2. School-context data come from school administrator reports on school policies, health services and other school characteristics and from the in-school interviews of students whose aggregated responses represent school census measures. From respondent reports of colleges attended, college context data have been linked to individual records. Family-context data come from parent questionnaires, adolescent in-school and in-home questionnaires and interviews with siblings and additional adolescents living in the same household.

Adolescents were asked to nominate friends and sexual and romantic partners from the school rosters in the in-school and in-home surveys at Waves I and II. Peer networks characteristics can be constructed by linking friends’ data and constructing variables based on friends’ responses, and similar measures can be constructed for linked romantic and sexual partners. These peer- and dyad-context measures constitute the social network data, including information on friendship networks, sexual networks and friendship and relationship dyads. Respondents’ home residences have been geocoded at each interview wave, and contextual data on the neighbourhood, community and state have been merged to all individual records. Nearly 12 000 environmental data elements at multiple geographical levels are available across waves. This includes such information as race, ethnic, foreign-born and religious denomination composition, poverty rates, crime statistics, STI prevalence, divorce and child support laws, welfare policies, cigarette taxes, the proximity and number of parks, sidewalks, recreation centres, fast food restaurants, alcohol outlets and other physical and social characteristics of the environments in which young people live. Table 3 shows the array of survey and biological data in Add Health. The top panel lists the domains covered by the survey instruments at each wave, including individual-level data on household and family structure, personality, religiosity and spirituality, relationships, sexual behaviour, contraception, pregnancy, children and parenting, sleep patterns, physical activity, diet, substance use/abuse, violence, delinquency, involvement with the criminal justice system, education history, work experiences, military service, chronic and disabling conditions, injury, mental health, suicide and health service access and use. Even though respondents were first interviewed in early adolescence, there are data on infancy (birthweight) and childhood (e.g. maltreatment, chronic conditions, attention deficit hyperactivity disorder) and complete data on fertility outcomes (there were more than 14 500 births to Add Health respondents by Wave IV). Survey and biomarker domains across Waves I-V in Add Health Survey and biomarker domains across Waves I-V in Add Health The bottom panel of Table 3 shows the biological measures available across waves. The original study design included important features for understanding biological processes in health and developmental trajectories across the life course, including an embedded genetic sample with more than 3000 pairs of adolescents with varying biological resemblance (see Figure 1) and measurement of height and weight to track the obesity epidemic. At Wave III, urine and saliva samples were collected to test for STI and HIV,11,12 and buccal cell saliva was collected from twins and full siblings in the genetic subsample for DNA extraction.13 An expanded set of biological measures were collected at Wave IV, including biomarkers of cardiovascular health (blood pressure, pulse), metabolic processes (waist circumference, glycosylated haemoglobin, blood glucose, lipids), immune function (Epstein-Barr virus), inflammation (C-reactive protein) and a medications inventory. Repeat biomarker measures were collected at Wave V, including new markers of renal disease. Saliva DNA was collected from the full sample at Wave IV. Candidate loci in the dopamine and serotonin pathways have been genotyped and disseminated to the scientific community.14 Genome-wide genotyping was completed on 10 974 Wave IV respondents who consented to archive their specimens for further testing, and genome-wide association study (GWAS) data are available from the database of Genotypes and Phenotypes (dbGaP). Add Health maintains a biospecimen archive available for ancillary studies. Add Health has a large and multidisciplinary user base of more than 50 000 researchers around the world, who have published over 3500 peer-reviewed articles in more than 750 different disciplinary journals, and has been the data source for more than 800 master’s theses and dissertations. Publications are listed at [https://www.cpc.unc.edu/projects/addhealth/publications]. Early publications focused on the role of social context in the development of adolescent health, behaviour, expectations and attainment, finding important influences of family and school connectedness,15 peer influence,16–18 romantic relationships,19 and neighbourhoods.20–22 For example, adolescents with a greater number and higher quality of connections to their school and family had better physical and mental health and higher attainment than youth with Adolescents whose friendship networks included friends with highly parents were than those whose friends had parents to studies that romantic in adolescence can adolescent and is with higher rates of obesity and weight in publications an of chronic young including a prevalence of and prevalence of the longitudinal data, researchers have the developmental and health pathways to young adult Add Health data support longitudinal studies of partner substance and health during the early life course from adolescence into young Add Health has the obesity and outcomes for adolescents.

Impaired survival and long-term neurological problems in benign meningioma.
Purpose: To assess long-term functional outcome and survival among patients with meningioma World Health Organization (WHO) grade I.
Methods: Retrospective analysis of 205 patients after resection of WHO grade I intracranial meningioma from 1985 through 2003. Expected age- and sex-specific survival was calculated by applying Dutch life-table statistics to each patient for the individual duration of follow-up. Long-term functional outcome was assessed using a mailed questionnaire to the general practitioner.
Results: The mean duration of follow-up was 11.5 years. Survival at 5, 10, 15, and 20 years was 92%, 81%, 63%, and 53%, respectively, which is significantly lower than the expected survival (94%, 86%, 78%, and 66%, respectively). Survival was worse with higher age (P < .001). Survival among patients younger than 45 years and older than 65 years was comparable to the expected survival but significantly worse among patients aged 45-65 years. Analysis of the cause of death suggests an excess mortality associated with both brain tumor death and stroke (P = .07). Recurrence rates at 5, 10, and 15 years were 18%, 26%, and 32%, respectively. Higher Simpson grade (P < .001) and lower age (P = .02) were associated with a higher recurrence rate. In 29 patients (14%) receiving radiotherapy, the 5-year recurrence rate was 18% and the 5-year survival was only 58%. Long-term functioning (≥ 5 years after last treatment) could be assessed in 89 long-term survivors: 29 patients (33%) showed no deficits, and 60 (67%) showed at least 1 neurological symptom, of whom 24 (27%) were unable to perform normal daily activities.
Conclusion: Long-term survival in WHO grade I meningioma is challenged in patients more than 45 years of age. Excess mortality seems to be associated with both tumor recurrence and stroke. The majority of patients have long-term neurological problems.

Compliance assessment of ambulatory Alzheimer patients to aid therapeutic decisions by healthcare professionals.
Background: Compliance represents a major determinant for the effectiveness of pharmacotherapy. Compliance reports summarising electronically compiled compliance data qualify healthcare needs and can be utilised as part of a compliance enhancing intervention. Nevertheless, evidence-based information on a sufficient level of compliance is scarce complicating the interpretation of compliance reports. The purpose of our pilot study was to determine the compliance of ambulatory Alzheimer patients to antidementia drugs under routine therapeutic use using electronic monitoring. In addition, the forgiveness of donepezil (i.e. its ability to sustain adequate pharmacological response despite suboptimal compliance) was characterised and evidence-based guidance for the interpretation of compliance reports was intended to be developed.
Methods: We determined the compliance of four different antidementia drugs by electronic monitoring in 31 patients over six months. All patients were recruited from the gerontopsychiatric clinic of a university hospital as part of a pilot study. The so called medication event monitoring system (MEMS) was employed, consisting of a vial with a microprocessor in the lid which records the time (date, hour, minute) of every opening. Daily compliance served as primary outcome measure, defined as percentage of days with correctly administered doses of medication. In addition, pharmacokinetics and pharmacodynamics of donepezil were simulated to systematically assess therapeutic undersupply also incorporating study compliance patterns. Statistical analyses were performed with SPSS and Microsoft Excel.
Results: Median daily compliance was 94% (range 48%-99%). Ten patients (32%) were non-compliant at least for one month. One-sixth of patients taking donepezil displayed periods of therapeutic undersupply. For 10 mg and 5 mg donepezil once-daily dosing, the estimated forgiveness of donepezil was 80% and 90% daily compliance or two and one dosage omissions at steady state, respectively. Based on the simulation findings we developed rules for the evidence-based interpretation of donepezil compliance reports.
Conclusions: Compliance in ambulatory Alzheimer patients was for the first time assessed under routine conditions using electronic monitoring: On average compliance was relatively high but variable between patients. The approach of pharmacokinetic/pharmacodynamic in silico simulations was suitable to characterise the forgiveness of donepezil suggesting evidence-based recommendations for the interpretation of compliance reports.

The effectiveness of web-based programs on the reduction of childhood obesity in school-aged children: A systematic review.
Review objective: The objective of this review is to synthesise the best available evidence on the effectiveness of web-based programs on the reduction of childhood obesity in school age children.
Background: Childhood obesity is one of the most serious public health challenges of the 21st century. The problem is global and is steadily affecting many low- and middle-income countries, particularly in urban settings.[1] The prevalence has increased at an alarming rate globally.[2] The International Association for the Study of Obesity; estimates that up to 200 million school aged children are either overweight or obese, of those 40-50 million are classified as obese. Obesity has negative health impact in childhood, as well as in the long term. Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity. It is defined as a person's weight in kilograms divided by the square of his/her height in meters (kg/m). The World Health Organization defines overweight as BMI greater than or equal to 25 and BMI greater than or equal to 30 as obesity. Children two years of age or older with a BMI between the 85 and 94 percentile on age-growth charts are considered overweight; children with a BMI greater than the 95 percentile are considered obese. BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages worldwide. Measures of central obesity such as the waist:hip ratio and waist circumference can provide more robust indices of overall obesity-related health risk than BMI alone. A BMI z-score is a quantitative measure of the deviation of a specific BMI percentile from the mean of that population. A positive z-score indicates a child is heavier than the mean and a negative z-score indicates a child is lighter than the mean. Thus, a z-score compares the BMI of a given child to the BMI distribution for a population of children of the same age and sex. The incidence of obesity has more than doubled since 1980. Overweight and obesity now ranks as the fifth leading global risk for mortality. Sixty-five percent of the world's population lives in countries where childhood overweight and obesity kills more people than being underweight. In addition, 44% of the diabetes burden, 23% of the ischemic heart disease burden, and between 7% and 41% of certain cancer burdens are attributable to overweight and obesity. Childhood obesity continues to be a significant health problem in the United States. There has been a rapid rise in obesity among the school-age population despite efforts made by Healthy People 2010 in promoting weight management and physical activity. These on-going efforts have been extended to be part of the goals for Healthy People 2020. The United States Centers for Disease Control and Prevention calculated that approximately 17% children between the ages of two to nineteen years of age were at or above the 97 percentile for being obese. These figures are more than three times the anticipated 5% set in the Healthy People 2010 report. Overweight and obese children are likely to stay obese into adulthood and are more likely to develop non-communicable diseases like diabetes and cardiovascular diseases at a younger age. In addition to a higher risk of obesity and non-communicable diseases later in life, affected children experience adverse outcomes such as breathing difficulties, increased risk of fractures, hypertension, and early markers of cardiovascular disease, different forms of cancers, insulin resistance, and psychological effects. Childhood obesity is associated with a higher chance of obesity, premature death, and disability in adulthood. If a child is overweight before eight years of age, obesity in adulthood is likely to be more severe. Child and adolescent obesity is also associated with increased risk of emotional problems. Teens with weight problems tend to have much lower self-esteem and are less popular with their peers. Depression, anxiety, and obsessive compulsive disorder can also occur as a result of childhood obesity. In addition to the diseases associated with obesity, the economic consequences of obesity are enormous for families, health care systems, and the global economy. Direct medical costs include preventative, diagnostic, and treatment services related to overweight and associated co-morbidities. European nations spend 2-8% of their health care budgets on obesity, equating to 0.6% of their gross domestic product. In the United States, estimates based on 2008 data indicated that overweight and obesity account for $147 billion in total medical expenditure. This shows an increase from the $117 billion spent in the year 2000.While indirect costs of overweight and obesity on society can be significantly higher, they are often overlooked. These costs stem from childhood obesity continuing on to obesity in adulthood, which can then results in income lost from decreased productivity, reduced opportunities and restricted activity, illness, absenteeism, and premature death. In addition, there are high costs associated with the numerous infrastructure changes that societies must make to cope with obese people such as reinforced beds, operating tables and wheel chairs; enlarged turnstiles and seats in in public gathering spaces; and modifications to transportation safety standards. Obesity is reaching pandemic proportions across much of the world, and its consequences are set to impose unparalleled health, financial and social burdens on global society unless effective actions are taken to reverse the trend. Reducing the incidence of obesity in childhood can help children grow into adults with normal body weights and the tools necessary to sustain a health weight. Haerens, et al. explains the importance of school-based programs in dealing with the serious problem of childhood obesity and overweight. The school setting is known as having a powerful influence on student's eating and physical activities. Programs that may have a more positive impact are those that help increase physical activity and promote healthy foods in youth. Previous studies looking at the implementation of diet and exercise programs in schools were effective in changing food habits and increasing physical activity; however, few of these studies showed a reduction in body weight. The Planet Health study, conducted over a period of two years, focused on healthy life style and showed a reduction in obesity in girls but not in boys. The M-span study, a two-year study involving proper diet, exercise, and parental support showed a reduction of BMI only in boys. Haerens, et al. further explains that the above mentioned studies needed to be done in a more personalised manner in order to achieve more positive result; however, they are limited by the time consumption and financial demands necessary to carry out the proposed intervention. Haerens, et al. conducted a two year study of the effect of a program including physical activity, healthy eating, and parental support with a computer-tailored component on BMI and BMI z-score in boys and girls. This intervention resulted in significant reduction in BMI in girls only. Carlson, et al. conducted a 12-month web-based weight loss intervention program which included physical activity and dietary behaviour. The program was found to be a potential low cost method to positively impact public health and health behaviours. Furthermore, 55% of the participants in the intervention group compared with 35% in the control group made an improvement in moderate-to-vigorous physical activity and diet. Doyle, et al. conducted an randomised controlled trial evaluating the effects of an Internet delivered program targeting weight loss on 80 overweight ethnically diverse 12-17 year olds. BMI z-scores were reduced in the intervention group compared with the usual care group post intervention and the intervention group maintained their reduction in BMI z-score at the four month follow up; however, statistical significance was not achieved at the four month follow up due to improvements in weight loss in the usual care group over time. The United States Department of Health and Human Services report of 2009 indicates that school aged children spend an average of 7 hours and 11 minutes per day watching television, using a computer, and playing video games. Using these technology devices as educational tools could have significant impact by increasing knowledge about healthy choices. Web-based technology has become part of our children's life in the last decade providing the foundation to a large number of daily activities. The use of web-based technology may be one method to provide a more personalised intervention to reduce obesity in school-aged children. The search for previously conducted systematic reviews on the effectiveness of web based programs on obesity in children identified a systematic review conducted by An, et al., which included studies published between 1995 and April 2009. A critical appraisal of this systematic review determined it to be of reduced quality due to lack of transparency in reporting the details of the search strategy, inclusion and exclusion criteria, and assessment of the primary studies' methodological quality. The proposed systematic review will expand on the prior systematic review using the rigorous search strategy and assessment for methodological quality outlined below to identify the best available research to determine the effectiveness of web-based programs on childhood obesity. The current review will also seek to identify any more current research on the topic while expanding the inclusion criteria from the internet-based interventions included in An, et al. to other forms for web-based technologies, such as smart phones, that have become increasingly popular with this population. The use of the web for communication purposes came into existence in 1991, but it was not really until the mid to late 1990's that information professionals understood its usefulness and the magnitude of a medium that would have far-reaching positive consequences. This systematic review will include studies published from 1991 to the present date to identify all relevant studies on this topic.

Functional impairment in the remission phase of bipolar disorder.
Objectives: The purpose of this study was to evaluate functional impairment in a group of patients with bipolar disorder in remission and to determine the extent of relationships between overall functioning and current depressive, manic and panic spectrum symptoms.
Method: A subset of the patient population at the Pittsburgh site of the Systematic Treatment Enhancement Program in Bipolar Disorder (STEP-BD) study was evaluated in this study. The subsample comprises 103 male and female subjects with bipolar I disorder (n = 70), bipolar II disorder (n = 24), schizoaffective disorder - bipolar type (n = 4), or bipolar disorder NOS (n = 5). Subjects were evaluated in a period of remission (at least 4 weeks with no more than two depressive or manic symptoms). Subjects were assessed for overall functional status using the Work and Social Adjustment Scale (WSAS) and for current bipolar and panic spectrum symptoms using the Mood Spectrum Self-Report questionnaire (MOODS-SR) and Panic-Agoraphobic Spectrum Self-Report questionnaire (PAS-SR).
Results: The median WSAS total score in these remitted subjects was 14, indicating significant functional impairment. Regressing WSAS on current depressive, manic, and panic spectrum total scores, we observed a highly significant depressive spectrum effect (t = 4.9, df = 94, p < 0.0001), but non-significant panic and manic spectrum effects (t = 1.3, df = 94, p = 0.19 and t = -1.8, df = 94, p = 0.07, respectively).
Conclusion: Bipolar disorder is associated with functional deficits even during periods of sustained and substantial remission. The degree of functional impairment is correlated with the degree of depressive spectrum symptoms.
