Dose-dependent and joint associations between screen time, physical activity, and mental wellbeing in adolescents: an international observational study.

Background: Mental wellbeing in adolescents has declined considerably during past decades, making the identification of modifiable risk factors important. Prolonged screen time and insufficient physical activity appear to operate independently and synergistically to increase the risk of poor mental wellbeing in school-aged children. We aimed to examine the gender-stratified dose-dependent and joint associations of screen time and physical activity with mental wellbeing in adolescents. Methods: We used data from three rounds of Health Behaviour in School-aged Children cross-sectional surveys (2006, 2010, and 2014) from 42 European and North American countries. Survey participants, aged 11 years, 13 years, and 15 years, provided self-reported information by completing an anonymous questionnaire that included items on health indicators and related behaviours. We used the self-reported variables of life satisfaction and psychosomatic complaints as indicators of adolescents' mental wellbeing, combining these with the self-reported discretionary use of screens and engagement in physical activity. We used generalised additive models and multilevel regression modelling to examine the gender-stratified relationships between mental wellbeing and screen time and physical activity. Findings: Our sample included 577 475 adolescents (mean age 13·60 years, SD 1·64), with 296 542 (51·35%) girls and 280 933 (48·64%) boys. The mean reported life satisfaction score (on a scale of 0-10) was 7·70 (95% CI 7·69-7·71) in boys and 7·48 (7·46-7·50) in girls. Psychosomatic complaints were more common among girls (mean 9·26, 95% CI 9·23-9·28) than boys (6·89, 6·87-6·91). Generalised additive model analyses showed slightly non-linear associations of screen time and physical activity with life satisfaction and psychosomatic complaints for girls and boys. Detrimental associations between screen time and mental wellbeing started when screen time exceeded 1 h per day, whereas increases in physical activity levels were beneficially and monotonically associated with wellbeing. Multilevel modelling showed that screen time levels were negatively associated with life satisfaction and positively associated with psychosomatic complaints in a dose-dependent manner. Physical activity levels were positively associated with life satisfaction and negatively associated with psychosomatic complaints in a dose-dependent manner. Joint associations of screen time-physical activity with mental wellbeing showed that, compared with the least active participants with more than 8 h per day of screen time and no physical activity, most of the other screen time-physical activity groups had considerably higher life satisfaction and lower psychosomatic complaints. Interpretation: Higher levels of screen time and lower levels of physical activity were associated with lower life satisfaction and higher psychosomatic complaints among adolescents from high-income countries. Public health strategies to promote adolescents' mental wellbeing should aim to decrease screen time and increase physical activity simultaneously. Funding: None.

Teacher Network of Relationships Inventory: measurement invariance of academically at-risk students across ages 6 to 15.

We tested the longitudinal measurement invariance of the Teacher Network of Relationships Inventory (TNRI), a teacher-report measure of teacher-student relationship quality (TSRQ), on a sample of 784 academically at-risk students across ages 6 to 15 years by comparing the model for each subsequent year with that of the previous year(s). The TNRI was constructed with 22 items to form 3 correlated factors: Warmth, Conflict, and Intimacy. Cronbach's alphas ranged from .87 to .96 across 9 years. Both metric and scalar measurement invariance held for 9 years, indicating that scores on the TNRI have similar meaning across these ages. The TNRI also demonstrated measurement invariance across gender and race/ethnicity. Findings support that the TNRI is an appropriate measure for investigating substantive issues related to developmental changes in TSRQ from early childhood through adolescence, including gender and ethnic/racial differences in TSRQ across these ages. Based on repeated-measures ANOVAs, each scale decreased across the 9 years, although the growth patterns for scales differed somewhat: Conflict had a linearly decreasing pattern, Warmth declined most notably as students make the transition to adolescence, whereas Intimacy scores dropped off noticeably at the transition from early to late childhood. Research limitations and implications for practice are discussed.

Parents and Tots Together: Pilot randomized controlled trial of a family-based obesity prevention intervention in Canada.

Objective: To test the feasibility, acceptability and preliminary impact of Parents and Tots Together (PTT), a family-based obesity prevention intervention, in Canada. Participants: Canadian parents of preschoolers (aged 2-5 years). Setting: Ontario Early Years centres in southwestern Ontario. Intervention: A pilot randomized controlled trial involving 48 parents who received either the PTT intervention (n = 27) or an attention-matched control home safety intervention (n = 21). To evaluate the feasibility of PTT, we assessed participant retention and outcome evaluation completion rates. To evaluate acceptability, we assessed program attendance and parents' responses to program satisfaction surveys. To evaluate preliminary impact, we assessed children's body mass index (BMI) at baseline, after intervention (end of 9-week intervention) and at 9-month follow-up. As well, at each time point, parents completed surveys assessing stress and self-efficacy related to parenting, children's sleep, activity, TV viewing and diet. Outcomes: Retention rates were high in the intervention (93%) and control (84%) study arms, and 87% of parents reported that they would highly recommend PTT to a friend. At 9-month follow-up, intervention parents reported lower parenting stress (β^ = 15.83, 95% confidence interval [CI] -29.57, -2.07, p = 0.02) and greater self-efficacy in managing their child's behaviour (β^ = 0.16, 95% CI 0.002, 0.33, p = 0.05) than control parents. PTT had minimal influence on children's weight-related behaviours and BMI. Conclusions: The results suggest that PTT can feasibly be implemented and tested in the Canadian context. Preliminary impact results suggest that the program may be effective in changing general parenting; however, program content should be modified to adequately address children's weight-related behaviours.

The effectiveness of third wave cognitive behavioural therapies for children and adolescents: A systematic review and meta-analysis.

Objectives: Third wave cognitive behavioural therapies are increasingly used with children and adolescents. This meta-analysis aimed to determine the effectiveness of four third-wave interventions (acceptance and commitment therapy, compassion focused therapy, mindfulness-based cognitive therapy, and metacognitive therapy) for youth. Methods: Four electronic databases were used to identify randomized controlled trials, which tested effects related to health, well-being and functioning. Sensitivity analyses considering study quality were conducted and moderators were explored. Results: The results based on 50 RCTs meeting inclusion criteria indicated emotional symptoms/internalizing problems (g = -.68, 95% CI -.98 to -.37, k = 43, N = 3265), behavioural difficulties/externalizing problems (g = -.62, 95% CI -1.01 to -.22, k = 23, N = 1659), interference from difficulties (g = -.46, 95% CI -.87 to -.05, k = 21, N = 1786), third wave processes (g = .39, 95% CI .17 to .62, k = 22, N = 1900), wellbeing/flourishing (g = .76, 95% CI .35 to 1.17, k = 21, N = 1303) and physical health/pain (g = .72, 95% CI .01 to 1.44, k = 9, N = 1171) yielded significant effects. Effect for quality of life (g = .62, 95% CI -.08 to 1.31, k = 12, N = 1271) was non-significant. When analysing only those studies rated moderate-high quality, third wave interventions yielded significant superiority effects compared to controls for emotional symptoms/internalizing problems (g = -.55, 95% CI -.82 to -.27, k = 28, N = 2110), interference from difficulties (g = -.48, 95% CI -.90 to -.05, k = 21, N = 1605), third wave processes (g = .27, 95% CI .11 to .43, k = 18, N = 1692), well-being/flourishing (g = .50, 95% CI .18 to .81, k = 16, N = 1063), and quality of life (g = .32, 95% CI .04 to .60, k = 10, N = 1212). Behavioural difficulties/externalizing problems (g = -.38, 95% CI -.86 to .10, k = 15, N = 1351) and physical health/pain (g = .52, 95% CI -.14 to 1.17, k = 8, N = 1139) ceased to be significant. Widespread heterogeneity raised concerns about generalizability and follow-up data was relatively sparse. Conclusions: This meta-analysis finds promising results for use of third wave CBT with youth, though the review has limitations.

Child protection training for professionals to improve reporting of child abuse and neglect.

Background: Many nations require child-serving professionals to report known or suspected cases of significant child abuse and neglect to statutory child protection or safeguarding authorities. Considered globally, there are millions of professionals who fulfil these roles, and many more who will do so in future. Ensuring they are trained in reporting child abuse and neglect is a key priority for nations and organisations if efforts to address violence against children are to succeed. Objectives: To assess the effectiveness of training aimed at improving reporting of child abuse and neglect by professionals and to investigate possible components of effective training interventions. Search methods: We searched CENTRAL, MEDLINE, Embase, 18 other databases, and one trials register up to 4 June 2021. We also handsearched reference lists, selected journals, and websites, and circulated a request for studies to researchers via an email discussion list. Selection criteria: All randomised controlled trials (RCTs), quasi-RCTs, and controlled before-and-after studies examining the effects of training interventions for qualified professionals (e.g. teachers, childcare professionals, doctors, nurses, and mental health professionals) to improve reporting of child abuse and neglect, compared with no training, waitlist control, or alternative training (not related to child abuse and neglect). Data collection and analysis: We used methodological procedures described in the Cochrane Handbook for Systematic Reviews of Interventions. We synthesised training effects in meta-analysis where possible and summarised findings for primary outcomes (number of reported cases of child abuse and neglect, quality of reported cases, adverse events) and secondary outcomes (knowledge, skills, and attitudes towards the reporting duty). We used the GRADE approach to rate the certainty of the evidence. Main results: We included 11 trials (1484 participants), using data from 9 of the 11 trials in quantitative synthesis. Trials took place in high-income countries, including the USA, Canada, and the Netherlands, with qualified professionals. In 8 of the 11 trials, interventions were delivered in face-to-face workshops or seminars, and in 3 trials interventions were delivered as self-paced e-learning modules. Interventions were developed by experts and delivered by specialist facilitators, content area experts, or interdisciplinary teams. Only 3 of the 11 included studies were conducted in the past 10 years. Primary outcomes Three studies measured the number of cases of child abuse and neglect via participants' self-report of actual cases reported, three months after training. The results of one study (42 participants) favoured the intervention over waitlist, but the evidence is very uncertain (standardised mean difference (SMD) 0.81, 95% confidence interval (CI) 0.18 to 1.43; very low-certainty evidence). Three studies measured the number of cases of child abuse and neglect via participants' responses to hypothetical case vignettes immediately after training. A meta-analysis of two studies (87 participants) favoured training over no training or waitlist for training, but the evidence is very uncertain (SMD 1.81, 95% CI 1.30 to 2.32; very low-certainty evidence).  We identified no studies that measured the number of cases of child abuse and neglect via official records of reports made to child protection authorities, or adverse effects of training. Secondary outcomes Four studies measured professionals' knowledge of reporting duty, processes, and procedures postintervention. The results of one study (744 participants) may favour the intervention over waitlist for training (SMD 1.06, 95% CI 0.90 to 1.21; low-certainty evidence). Four studies measured professionals' knowledge of core concepts in all forms of child abuse and neglect postintervention. A meta-analysis of two studies (154 participants) favoured training over no training, but the evidence is very uncertain (SMD 0.68, 95% CI 0.35 to 1.01; very low-certainty evidence). Three studies measured professionals' knowledge of core concepts in child sexual abuse postintervention. A meta-analysis of these three studies (238 participants) favoured training over no training or waitlist for training, but the evidence is very uncertain (SMD 1.44, 95% CI 0.43 to 2.45; very low-certainty evidence). One study (25 participants) measured professionals' skill in distinguishing reportable and non-reportable cases postintervention. The results favoured the intervention over no training, but the evidence is very uncertain (SMD 0.94, 95% CI 0.11 to 1.77; very low-certainty evidence). Two studies measured professionals' attitudes towards the duty to report child abuse and neglect postintervention. The results of one study (741 participants) favoured the intervention over waitlist, but the evidence is very uncertain (SMD 0.61, 95% CI 0.47 to 0.76; very low-certainty evidence). Authors' conclusions: The studies included in this review suggest there may be evidence of improvements in training outcomes for professionals exposed to training compared with those who are not exposed. However, the evidence is very uncertain. We rated the certainty of evidence as low to very low, downgrading due to study design and reporting limitations. Our findings rest on a small number of largely older studies, confined to single professional groups. Whether similar effects would be seen for a wider range of professionals remains unknown. Considering the many professional groups with reporting duties, we strongly recommend further research to assess the effectiveness of training interventions, with a wider range of child-serving professionals. There is a need for larger trials that use appropriate methods for group allocation, and statistical methods to account for the delivery of training to professionals in workplace groups.

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.

Effectiveness of brief alcohol interventions in primary care populations.

Background: Excessive drinking is a significant cause of mortality, morbidity and social problems in many countries. Brief interventions aim to reduce alcohol consumption and related harm in hazardous and harmful drinkers who are not actively seeking help for alcohol problems. Interventions usually take the form of a conversation with a primary care provider and may include feedback on the person's alcohol use, information about potential harms and benefits of reducing intake, and advice on how to reduce consumption. Discussion informs the development of a personal plan to help reduce consumption. Brief interventions can also include behaviour change or motivationally-focused counselling. This is an update of a Cochrane Review published in 2007. Objectives: To assess the effectiveness of screening and brief alcohol intervention to reduce excessive alcohol consumption in hazardous or harmful drinkers in general practice or emergency care settings. Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and 12 other bibliographic databases to September 2017. We searched Alcohol and Alcohol Problems Science Database (to December 2003, after which the database was discontinued), trials registries, and websites. We carried out handsearching and checked reference lists of included studies and relevant reviews. Selection criteria: We included randomised controlled trials (RCTs) of brief interventions to reduce hazardous or harmful alcohol consumption in people attending general practice, emergency care or other primary care settings for reasons other than alcohol treatment. The comparison group was no or minimal intervention, where a measure of alcohol consumption was reported. 'Brief intervention' was defined as a conversation comprising five or fewer sessions of brief advice or brief lifestyle counselling and a total duration of less than 60 minutes. Any more was considered an extended intervention. Digital interventions were not included in this review. Data collection and analysis: We used standard methodological procedures expected by Cochrane. We carried out subgroup analyses where possible to investigate the impact of factors such as gender, age, setting (general practice versus emergency care), treatment exposure and baseline consumption. Main results: We included 69 studies that randomised a total of 33,642 participants. Of these, 42 studies were added for this update (24,057 participants). Most interventions were delivered in general practice (38 studies, 55%) or emergency care (27 studies, 39%) settings. Most studies (61 studies, 88%) compared brief intervention to minimal or no intervention. Extended interventions were compared with brief (4 studies, 6%), minimal or no intervention (7 studies, 10%). Few studies targeted particular age groups: adolescents or young adults (6 studies, 9%) and older adults (4 studies, 6%). Mean baseline alcohol consumption was 244 g/week (30.5 standard UK units) among the studies that reported these data. Main sources of bias were attrition and lack of provider or participant blinding. The primary meta-analysis included 34 studies (15,197 participants) and provided moderate-quality evidence that participants who received brief intervention consumed less alcohol than minimal or no intervention participants after one year (mean difference (MD) -20 g/week, 95% confidence interval (CI) -28 to -12). There was substantial heterogeneity among studies (I² = 73%). A subgroup analysis by gender demonstrated that both men and women reduced alcohol consumption after receiving a brief intervention. We found moderate-quality evidence that brief alcohol interventions have little impact on frequency of binges per week (MD -0.08, 95% CI -0.14 to -0.02; 15 studies, 6946 participants); drinking days per week (MD -0.13, 95% CI -0.23 to -0.04; 11 studies, 5469 participants); or drinking intensity (-0.2 g/drinking day, 95% CI -3.1 to 2.7; 10 studies, 3128 participants).We found moderate-quality evidence of little difference in quantity of alcohol consumed when extended and no or minimal interventions were compared (-14 g/week, 95% CI -37 to 9; 6 studies, 1296 participants). There was little difference in binges per week (-0.08, 95% CI -0.28 to 0.12; 2 studies, 456 participants; moderate-quality evidence) or difference in days drinking per week (-0.45, 95% CI -0.81 to -0.09; 2 studies, 319 participants; moderate-quality evidence). Extended versus no or minimal intervention provided little impact on drinking intensity (9 g/drinking day, 95% CI -26 to 9; 1 study, 158 participants; low-quality evidence).Extended intervention had no greater impact than brief intervention on alcohol consumption, although findings were imprecise (MD 2 g/week, 95% CI -42 to 45; 3 studies, 552 participants; low-quality evidence). Numbers of binges were not reported for this comparison, but one trial suggested a possible drop in days drinking per week (-0.5, 95% CI -1.2 to 0.2; 147 participants; low-quality evidence). Results from this trial also suggested very little impact on drinking intensity (-1.7 g/drinking day, 95% CI -18.9 to 15.5; 147 participants; very low-quality evidence).Only five studies reported adverse effects (very low-quality evidence). No participants experienced any adverse effects in two studies; one study reported that the intervention increased binge drinking for women and two studies reported adverse events related to driving outcomes but concluded they were equivalent in both study arms. Sources of funding were reported by 67 studies (87%). With two exceptions, studies were funded by government institutes, research bodies or charitable foundations. One study was partly funded by a pharmaceutical company and a brewers association, another by a company developing diagnostic testing equipment. Authors' conclusions: We found moderate-quality evidence that brief interventions can reduce alcohol consumption in hazardous and harmful drinkers compared to minimal or no intervention. Longer counselling duration probably has little additional effect. Future studies should focus on identifying the components of interventions which are most closely associated with effectiveness.

The Amagugu intervention for disclosure of maternal HIV to uninfected primary school-aged children in South Africa: a randomised controlled trial.

Background: Increasing populations of children who are HIV-exposed but uninfected will face the challenge of disclosure of parental HIV infection status. We aimed to test the efficacy of an intervention to increase maternal HIV-disclosure to primary school-aged HIV-uninfected children. Methods: This randomised controlled trial was done at the Africa Health Research Institute in KwaZulu-Natal, South Africa. Women who had tested HIV positive at least 6 months prior, had initiated HIV treatment or been enrolled in pretreatment HIV care, and had an HIV-uninfected child (aged 6-10 years) were randomly allocated to either the Amagugu intervention or enhanced standard of care, using a computerised algorithm based on simple randomisation and equal probabilities of being assigned to each group. Lay counsellors delivered the Amagugu intervention, which included six home-based counselling sessions of 1-2 h and materials and activities to support HIV disclosure and parent-led health promotion. The enhanced standard of care included one clinic-based counselling session. Outcome measures at 3 months, 6 months, and 9 months post baseline were done by follow-up assessors who were masked to participants' group and counsellor allocation. The primary outcome was maternal HIV disclosure (full [using the word HIV], partial [using the word virus], or none) at 9 months post baseline. We did the analysis in the intention-to-treat population. This study is registered with ClinicalTrials.gov (NCT01922882). Findings: Between July 1, 2013, and Dec 31, 2014, we randomly assigned 464 participants to the Amagugu intervention (n=235) or enhanced standard of care (n=229). 428 (92%) participants completed the 9 month assessment by Sept 3, 2015. Disclosure at any level was more common in the Amagugu intervention group (n=204 [87%]) than in the enhanced standard-of-care group (n=128 [56%]; adjusted odds ratio 9·88, 95% CI 5·55-17·57; p<0·0001). Full disclosure was also more common in the Amagugu intervention group (n=150 [64%]) than in the enhanced standard-of-care group (n=98 [43%]; 4·13, 2·80-6·11; p<0·0001). Treatment-unrelated adverse effects were reported for 17 participants in the Amagugu intervention group versus six in the enhanced standard-of-care group; adverse effects included domestic violence (five [2%] in the Amagugu intervention group vs one [<1%] in the enhanced standard-of-care group), sexual assault (four [2%] vs one [<1%]), participant illness or death (four [2%] vs four [2%]), and family member illness or death (four [2%] vs none). No treatment-related deaths occurred. Interpretation: The lay-counsellor-driven Amagugu intervention to aid parental disclosure has potential for wide-scale implementation after further effectiveness research and could be adapted to other target populations and other diseases. Further follow-up and effectiveness research is required. Funding: National Institutes of Health.

Mood and cue reactivity among smokers with a history of major depression: the role of rumination and impulsivity.

The present study tested the influence of rumination and impulsivity on experimentally induced negative mood among a sample of smokers with a lifetime history of major depression (MDD Hx+). Participants (N = 40) were categorized into four vulnerability groups: nonvulnerable (low rumination, low impulsivity), ruminative (elevated rumination, low impulsivity), impulsive (low rumination, elevated impulsivity), and vulnerable (elevated rumination, elevated impulsivity). Participants were counterbalanced to four experimental conditions, using a combination of a mood induction (negative mood induction vs. control) and smoking cue (in vivo cigarette vs. control cue). Although all participants reported greater anger responses when exposed to the negative mood induction versus control, vulnerable and ruminative smokers reported significantly greater anger responses than impulsive and nonvulnerable smokers [F(9,87) = 2.93, p = .038, Mse = 79.38]. Implications are discussed.

Prevalence of Health Misinformation on Social Media: Systematic Review.

Background: Although at present there is broad agreement among researchers, health professionals, and policy makers on the need to control and combat health misinformation, the magnitude of this problem is still unknown. Consequently, it is fundamental to discover both the most prevalent health topics and the social media platforms from which these topics are initially framed and subsequently disseminated. Objective: This systematic review aimed to identify the main health misinformation topics and their prevalence on different social media platforms, focusing on methodological quality and the diverse solutions that are being implemented to address this public health concern. Methods: We searched PubMed, MEDLINE, Scopus, and Web of Science for articles published in English before March 2019, with a focus on the study of health misinformation in social media. We defined health misinformation as a health-related claim that is based on anecdotal evidence, false, or misleading owing to the lack of existing scientific knowledge. We included (1) articles that focused on health misinformation in social media, including those in which the authors discussed the consequences or purposes of health misinformation and (2) studies that described empirical findings regarding the measurement of health misinformation on these platforms. Results: A total of 69 studies were identified as eligible, and they covered a wide range of health topics and social media platforms. The topics were articulated around the following six principal categories: vaccines (32%), drugs or smoking (22%), noncommunicable diseases (19%), pandemics (10%), eating disorders (9%), and medical treatments (7%). Studies were mainly based on the following five methodological approaches: social network analysis (28%), evaluating content (26%), evaluating quality (24%), content/text analysis (16%), and sentiment analysis (6%). Health misinformation was most prevalent in studies related to smoking products and drugs such as opioids and marijuana. Posts with misinformation reached 87% in some studies. Health misinformation about vaccines was also very common (43%), with the human papilloma virus vaccine being the most affected. Health misinformation related to diets or pro-eating disorder arguments were moderate in comparison to the aforementioned topics (36%). Studies focused on diseases (ie, noncommunicable diseases and pandemics) also reported moderate misinformation rates (40%), especially in the case of cancer. Finally, the lowest levels of health misinformation were related to medical treatments (30%). Conclusions: The prevalence of health misinformation was the highest on Twitter and on issues related to smoking products and drugs. However, misinformation on major public health issues, such as vaccines and diseases, was also high. Our study offers a comprehensive characterization of the dominant health misinformation topics and a comprehensive description of their prevalence on different social media platforms, which can guide future studies and help in the development of evidence-based digital policy action plans.

Behavioural and cognitive-behavioural interventions for outwardly directed aggressive behaviour in people with intellectual disabilities.

Background: Outwardly directed aggressive behaviour in people with intellectual disabilities is a significant issue that may lead to poor quality of life, social exclusion and inpatient psychiatric admissions. Cognitive and behavioural approaches have been developed to manage aggressive behaviour but the effectiveness of these interventions on reducing aggressive behaviour and other outcomes are unclear. This is the third update of this review and adds nine new studies, resulting in a total of 15 studies in this review. Objectives: To evaluate the efficacy of behavioural and cognitive-behavioural interventions on outwardly directed aggressive behaviour compared to usual care, wait-list controls or no treatment in people with intellectual disability. We also evaluated enhanced interventions compared to non-enhanced interventions. Search methods: We used standard, extensive Cochrane search methods. The latest search date was March 2022. We revised the search terms to include positive behaviour support (PBS). Selection criteria: We included randomised and quasi-randomised trials of children and adults with intellectual disability of any duration, setting and any eligible comparator. Data collection and analysis: We used standard Cochrane methods. Our primary outcomes were change in 1. aggressive behaviour, 2. ability to control anger, and 3. adaptive functioning, and 4. Adverse effects: Our secondary outcomes were change in 5. mental state, 6. medication, 7. care needs and 8. quality of life, and 9. frequency of service utilisation and 10. user satisfaction data. We used GRADE to assess certainty of evidence for each outcome. We expressed treatment effects as mean differences (MD) or odds ratios (OR), with 95% confidence intervals (CI). Where possible, we pooled data using a fixed-effect model. Main results: This updated version comprises nine new studies giving 15 included studies and 921 participants. The update also adds new interventions including parent training (two studies), mindfulness-based positive behaviour support (MBPBS) (two studies), reciprocal imitation training (RIT; one study) and dialectical behavioural therapy (DBT; one study). It also adds two new studies on PBS. Most studies were based in the community (14 studies), and one was in an inpatient forensic service. Eleven studies involved adults only. The remaining studies involved children (one study), children and adolescents (one study), adolescents (one study), and adolescents and adults (one study). One study included boys with fragile X syndrome. Six studies were conducted in the UK, seven in the USA, one in Canada and one in Germany. Only five studies described sources of funding. Four studies compared anger management based on cognitive behaviour therapy to a wait-list or no treatment control group (n = 263); two studies compared PBS with treatment as usual (TAU) (n = 308); two studies compared carer training on mindfulness and PBS with PBS only (n = 128); two studies involving parent training on behavioural approaches compared to wait-list control or TAU (n = 99); one study of mindfulness to a wait-list control (n = 34); one study of adapted dialectal behavioural therapy compared to wait-list control (n = 21); one study of RIT compared to an active control (n = 20) and one study of modified relaxation compared to an active control group (n = 12). There was moderate-certainty evidence that anger management may improve severity of aggressive behaviour post-treatment (MD -3.50, 95% CI -6.21 to -0.79; P = 0.01; 1 study, 158 participants); very low-certainty evidence that it might improve self-reported ability to control anger (MD -8.38, 95% CI -14.05 to -2.71; P = 0.004, I2 = 2%; 3 studies, 212 participants), adaptive functioning (MD -21.73, 95% CI -36.44 to -7.02; P = 0.004; 1 study, 28 participants) and psychiatric symptoms (MD -0.48, 95% CI -0.79 to -0.17; P = 0.002; 1 study, 28 participants) post-treatment; and very low-certainty evidence that it does not improve quality of life post-treatment (MD -5.60, 95% CI -18.11 to 6.91; P = 0.38; 1 study, 129 participants) or reduce service utilisation and costs at 10 months (MD 102.99 British pounds, 95% CI -117.16 to 323.14; P = 0.36; 1 study, 133 participants). There was moderate-certainty evidence that PBS may reduce aggressive behaviour post-treatment (MD -7.78, 95% CI -15.23 to -0.32; P = 0.04, I2 = 0%; 2 studies, 275 participants) and low-certainty evidence that it probably does not reduce aggressive behaviour at 12 months (MD -5.20, 95% CI -13.27 to 2.87; P = 0.21; 1 study, 225 participants). There was low-certainty evidence that PBS does not improve mental state post-treatment (OR 1.44, 95% CI 0.83 to 2.49; P = 1.21; 1 study, 214 participants) and very low-certainty evidence that it might not reduce service utilisation at 12 months (MD -448.00 British pounds, 95% CI -1660.83 to 764.83; P = 0.47; 1 study, 225 participants). There was very low-certainty evidence that mindfulness may reduce incidents of physical aggression (MD -2.80, 95% CI -4.37 to -1.23; P < 0.001; 1 study; 34 participants) and low-certainty evidence that MBPBS may reduce incidents of aggression post-treatment (MD -10.27, 95% CI -14.86 to -5.67; P < 0.001, I2 = 87%; 2 studies, 128 participants). Reasons for downgrading the certainty of evidence were risk of bias (particularly selection and performance bias); imprecision (results from single, often small studies, wide CIs, and CIs crossing the null effect); and inconsistency (statistical heterogeneity). Authors' conclusions: There is moderate-certainty evidence that cognitive-behavioural approaches such as anger management and PBS may reduce outwardly directed aggressive behaviour in the short term but there is less certainty about the evidence in the medium and long term, particularly in relation to other outcomes such as quality of life. There is some evidence to suggest that combining more than one intervention may have cumulative benefits. Most studies were small and there is a need for larger, robust randomised controlled trials, particularly for interventions where the certainty of evidence is very low. More trials are needed that focus on children and whether psychological interventions lead to reductions in the use of psychotropic medications.

Short-course radiotherapy followed by chemotherapy before total mesorectal excision (TME) versus preoperative chemoradiotherapy, TME, and optional adjuvant chemotherapy in locally advanced rectal cancer (RAPIDO): a randomised, open-label, phase 3 trial.

Background: Systemic relapses remain a major problem in locally advanced rectal cancer. Using short-course radiotherapy followed by chemotherapy and delayed surgery, the Rectal cancer And Preoperative Induction therapy followed by Dedicated Operation (RAPIDO) trial aimed to reduce distant metastases without compromising locoregional control. Methods: In this multicentre, open-label, randomised, controlled, phase 3 trial, participants were recruited from 54 centres in the Netherlands, Sweden, Spain, Slovenia, Denmark, Norway, and the USA. Patients were eligible if they were aged 18 years or older, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, had a biopsy-proven, newly diagnosed, primary, locally advanced rectal adenocarcinoma, which was classified as high risk on pelvic MRI (with at least one of the following criteria: clinical tumour [cT] stage cT4a or cT4b, extramural vascular invasion, clinical nodal [cN] stage cN2, involved mesorectal fascia, or enlarged lateral lymph nodes), were mentally and physically fit for chemotherapy, and could be assessed for staging within 5 weeks before randomisation. Eligible participants were randomly assigned (1:1), using a management system with a randomly varying block design (each block size randomly chosen to contain two to four allocations), stratified by centre, ECOG performance status, cT stage, and cN stage, to either the experimental or standard of care group. All investigators remained masked for the primary endpoint until a prespecified number of events was reached. Patients allocated to the experimental treatment group received short-course radiotherapy (5 × 5 Gy over a maximum of 8 days) followed by six cycles of CAPOX chemotherapy (capecitabine 1000 mg/m2 orally twice daily on days 1-14, oxaliplatin 130 mg/m2 intravenously on day 1, and a chemotherapy-free interval between days 15-21) or nine cycles of FOLFOX4 (oxaliplatin 85 mg/m2 intravenously on day 1, leucovorin [folinic acid] 200 mg/m2 intravenously on days 1 and 2, followed by bolus fluorouracil 400 mg/m2 intravenously and fluorouracil 600 mg/m2 intravenously for 22 h on days 1 and 2, and a chemotherapy-free interval between days 3-14) followed by total mesorectal excision. Choice of CAPOX or FOLFOX4 was per physician discretion or hospital policy. Patients allocated to the standard of care group received 28 daily fractions of 1·8 Gy up to 50·4 Gy or 25 fractions of 2·0 Gy up to 50·0 Gy (per physician discretion or hospital policy), with concomitant twice-daily oral capecitabine 825 mg/m2 followed by total mesorectal excision and, if stipulated by hospital policy, adjuvant chemotherapy with eight cycles of CAPOX or 12 cycles of FOLFOX4. The primary endpoint was 3-year disease-related treatment failure, defined as the first occurrence of locoregional failure, distant metastasis, new primary colorectal tumour, or treatment-related death, assessed in the intention-to-treat population. Safety was assessed by intention to treat. This study is registered with the EudraCT, 2010-023957-12, and ClinicalTrials.gov, NCT01558921, and is now complete. Findings: Between June 21, 2011, and June 2, 2016, 920 patients were enrolled and randomly assigned to a treatment, of whom 912 were eligible (462 in the experimental group; 450 in the standard of care group). Median follow-up was 4·6 years (IQR 3·5-5·5). At 3 years after randomisation, the cumulative probability of disease-related treatment failure was 23·7% (95% CI 19·8-27·6) in the experimental group versus 30·4% (26·1-34·6) in the standard of care group (hazard ratio 0·75, 95% CI 0·60-0·95; p=0·019). The most common grade 3 or higher adverse event during preoperative therapy in both groups was diarrhoea (81 [18%] of 460 patients in the experimental group and 41 [9%] of 441 in the standard of care group) and neurological toxicity during adjuvant chemotherapy in the standard of care group (16 [9%] of 187 patients). Serious adverse events occurred in 177 (38%) of 460 participants in the experimental group and, in the standard of care group, in 87 (34%) of 254 patients without adjuvant chemotherapy and in 64 (34%) of 187 with adjuvant chemotherapy. Treatment-related deaths occurred in four participants in the experimental group (one cardiac arrest, one pulmonary embolism, two infectious complications) and in four participants in the standard of care group (one pulmonary embolism, one neutropenic sepsis, one aspiration, one suicide due to severe depression). Interpretation: The observed decreased probability of disease-related treatment failure in the experimental group is probably indicative of the increased efficacy of preoperative chemotherapy as opposed to adjuvant chemotherapy in this setting. Therefore, the experimental treatment can be considered as a new standard of care in high-risk locally advanced rectal cancer.

A Social Media Peer Group for Mothers To Prevent Obesity from Infancy: The Grow2Gether Randomized Trial.

Background: Few studies have addressed obesity prevention among low-income families whose infants are at increased obesity risk. We tested a Facebook peer-group intervention for low-income mothers to foster behaviors promoting healthy infant growth. Methods: In this randomized controlled trial, 87 pregnant women (Medicaid insured, BMI ≥25 kg/m2) were randomized to the Grow2Gether intervention or text message appointment reminders. Grow2Gether participants joined a private Facebook group of 9-13 women from 2 months before delivery until infant age 9 months. A psychologist facilitated groups featuring a curriculum of weekly videos addressing feeding, sleep, parenting, and maternal well-being. Feasibility was assessed using the frequency and content of participation, and acceptability using surveys. Maternal beliefs and behaviors and infant growth were assessed at birth, 2, 4, 6, and 9 months. Differences in infant growth between study arms were explored. We conducted intention-to-treat analyses using quasi-least-squares regression. Results: Eighty-eight percent (75/85) of intervention participants (42% (36/85) food insecure, 88% (75/85) black) reported the group was helpful. Participants posted 30 times/group/week on average. At 9 months, the intervention group had significant improvement in feeding behaviors (Infant Feeding Style Questionnaire) compared to the control group (p = 0.01, effect size = 0.45). Intervention group mothers were significantly less likely to pressure infants to finish food and, at age 6 months, give cereal in the bottle. Differences were not observed for other outcomes, including maternal feeding beliefs or infant weight-for-length. Conclusions: A social media peer-group intervention was engaging and significantly impacted certain feeding behaviors in families with infants at high risk of obesity.

Early liver transplantation for severe alcohol-related hepatitis not responding to medical treatment: a prospective controlled study.

Background: Early liver transplantation for severe alcohol-related hepatitis is an emerging treatment option. We aimed to assess the risk of alcohol relapse 2 years after early liver transplantation for alcohol-related hepatitis compared with liver transplantation for alcohol-related cirrhosis after at least 6 months of abstinence. Methods: We conducted a multicentre, non-randomised, non-inferiority, controlled study in 19 French and Belgian hospitals. All participants were aged 18 years or older. There were three groups of patients recruited prospectively: patients with severe alcohol-related hepatitis who did not respond to medical treatment and were eligible for early liver transplantation according to a new selection scoring system based on social and addiction items that can be quantified in points (early transplantation group); patients with alcohol-related cirrhosis listed for liver transplantation after at least 6 months of abstinence (standard transplantation group); patients with severe alcohol-related hepatitis not responding to medical treatment not eligible for early liver transplantation according to the selection score (not eligible for early transplantation group), this group did not enter any further liver transplantation processes. We also defined a historical control group of patients with severe alcohol-related hepatitis unresponsive to medical therapy and non-transplanted. The primary outcome was the non-inferiority of 2-year rate of alcohol relapse after transplantation in the early transplantation group compared with the standard transplantation group using the alcohol timeline follow back (TLFB) method and a prespecified non-inferiority margin of 10%. Secondary outcomes were the pattern of alcohol relapse, 2-year survival rate post-transplant in the early transplantation group compared with the standard transplantation group, and 2-year overall survival in the early transplantation group compared with patients in the not eligible for early transplantation group and historical controls. This trial is registered with ClinicalTrials.gov, NCT01756794. Findings: Between Dec 5, 2012, and June 30, 2016, we included 149 patients with severe alcohol-related hepatitis: 102 in the early transplantation group and 47 in the not eligible for early transplantation group. 129 patients were included in the standard transplantation group. 68 patients in the early transplantation group and 93 patients in the standard transplantation group received a liver transplant. 23 (34%) patients relapsed in the early transplantation group, and 23 (25%) patients relapsed in the standard transplantation group; therefore, the non-inferiority of early transplantation versus standard transplantation was not demonstrated (absolute difference 9·1% [95% CI -∞ to 21·1]; p=0·45). The 2-year rate of high alcohol intake was greater in the early transplantation group than the standard transplantation group (absolute difference 16·7% [95% CI 5·8-27·6]) The time spent drinking alcohol was not different between the two groups (standardised difference 0·24 [95% CI -0·07 to 0·55]), but the time spent drinking a large quantity of alcohol was higher in the early transplantation group than the standard transplantation group (standardised difference 0·50 [95% CI 0·17-0·82]). 2-year post-transplant survival was similar between the early transplantation group and the standard transplantation group (hazard ratio [HR] 0·87 [95% CI 0·33-2·26]); 2-year overall survival was higher in the early transplantation group than the not eligible for early transplantation group and historical controls (HR 0·27 [95% CI 0·16-0·47] and 0·21 [0·13-0·32]). Interpretation: We cannot conclude non-inferiority in terms of rate of alcohol relapse post-transplant between early liver transplantation and standard transplantation. High alcohol intake is more frequent after early liver transplantation. This prospective controlled study confirms the important survival benefit related to early liver transplantation for severe alcohol-related hepatitis; and this study provides objective data on survival and alcohol relapse to tailor the management of patients with severe alcohol-related hepatitis.

A Parent Treatment Program for Preschoolers With Obesity: A Randomized Controlled Trial.

Background and objectives: Early obesity treatment seems to be the most effective, but few treatments exist. In this study, we examine the effectiveness of a parent-only treatment program with and without booster sessions (Booster or No Booster) focusing on parenting practices and standard treatment (ST). Methods: Families of children 4 to 6 years of age with obesity were recruited from 68 child care centers in Stockholm County and randomly assigned to a parent-only program (10 weeks) with or without boosters (9 months) or to ST. Treatment effects on primary outcomes (BMI z score) and secondary outcomes (BMI and waist circumference) during a 12-month period were examined with linear mixed models. The influence of sociodemographic factors was examined by 3-way interactions. The clinically significant change in BMI z score (-0.5) was assessed with risk ratios. Results: A total of 174 children (mean age: 5.3 years [SD = 0.8]; BMI z score: 3.0 [SD = 0.6], 56% girls) and their parents (60% foreign background; 39% university degree) were included in the analysis (Booster, n = 44; No Booster, n = 43; ST, n = 87). After 12 months, children in the parent-only treatment had a greater reduction in their BMI z score (0.30; 95% confidence interval [CI]: -0.45 to -0.15) compared with ST (0.07; 95% CI: -0.19 to 0.05). Comparing all 3 groups, improvements in weight status were only seen for the Booster group (-0.54; 95% CI: -0.77 to -0.30). The Booster group was 4.8 times (95% CI: 2.4 to 9.6) more likely to reach a clinically significant reduction of ≥0.5 of the BMI z score compared with ST. Conclusion: A parent-only treatment with boosters outperformed standard care for obesity in preschoolers.

3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for post-traumatic stress disorder in military veterans, firefighters, and police officers: a randomised, double-blind, dose-response, phase 2 clinical trial.

Background: Post-traumatic stress disorder (PTSD) is prevalent in military personnel and first responders, many of whom do not respond to currently available treatments. This study aimed to assess the efficacy and safety of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for treating chronic PTSD in this population. Methods: We did a randomised, double-blind, dose-response, phase 2 trial at an outpatient psychiatric clinic in the USA. We included service personnel who were 18 years or older, with chronic PTSD duration of 6 months or more, and who had a Clinician-Administered PTSD Scale (CAPS-IV) total score of 50 or greater. Using a web-based randomisation system, we randomly assigned participants (1:1:2) to three different dose groups of MDMA plus psychotherapy: 30 mg (active control), 75 mg, or 125 mg. We masked investigators, independent outcome raters, and participants until after the primary endpoint. MDMA was administered orally in two 8-h sessions with concomitant manualised psychotherapy. The primary outcome was mean change in CAPS-IV total score from baseline to 1 month after the second experimental session. Participants in the 30 mg and 75 mg groups subsequently underwent three 100-125 mg MDMA-assisted psychotherapy sessions in an open-label crossover, and all participants were assessed 12 months after the last MDMA session. Safety was monitored through adverse events, spontaneously reported expected reactions, vital signs, and suicidal ideation and behaviour. This study is registered with ClinicalTrials.gov, number NCT01211405. Findings: Between Nov 10, 2010, and Jan 29, 2015, 26 veterans and first responders met eligibility criteria and were randomly assigned to receive 30 mg (n=7), 75 mg (n=7), or 125 mg (n=12) of MDMA plus psychotherapy. At the primary endpoint, the 75 mg and 125 mg groups had significantly greater decreases in PTSD symptom severity (mean change CAPS-IV total scores of -58·3 [SD 9·8] and -44·3 [28·7]; p=0·001) than the 30 mg group (-11·4 [12·7]). Compared with the 30 mg group, Cohen's d effect sizes were large: 2·8 (95% CI 1·19-4·39) for the 75 mg group and 1·1 (0·04-2·08) for the 125 mg group. In the open-label crossover with full-dose MDMA (100-125 mg), PTSD symptom severity significantly decreased in the group that had previously received 30 mg (p=0·01), whereas no further significant decreases were observed in the group that previously achieved a large response after 75 mg doses in the blinded segment (p=0·81). PTSD symptoms were significantly reduced at the 12-month follow-up compared with baseline after all groups had full-dose MDMA (mean CAPS-IV total score of 38·8 [SD 28·1] vs 87·1 [16·1]; p<0·0001). 85 adverse events were reported by 20 participants. Of these adverse events, four (5%) were serious: three were deemed unrelated and one possibly related to study drug treatment. Interpretation: Active doses (75 mg and 125 mg) of MDMA with adjunctive psychotherapy in a controlled setting were effective and well tolerated in reducing PTSD symptoms in veterans and first responders.

The Healthy Activity Program (HAP), a lay counsellor-delivered brief psychological treatment for severe depression, in primary care in India: a randomised controlled trial.

Background: Although structured psychological treatments are recommended as first-line interventions for depression, only a small fraction of people globally receive these treatments because of poor access in routine primary care. We assessed the effectiveness and cost-effectiveness of a brief psychological treatment (Healthy Activity Program [HAP]) for delivery by lay counsellors to patients with moderately severe to severe depression in primary health-care settings. Methods: In this randomised controlled trial, we recruited participants aged 18-65 years scoring more than 14 on the Patient Health Questionnaire 9 (PHQ-9) indicating moderately severe to severe depression from ten primary health centres in Goa, India. Pregnant women or patients who needed urgent medical attention or were unable to communicate clearly were not eligible. Participants were randomly allocated (1:1) to enhanced usual care (EUC) alone or EUC combined with HAP in randomly sized blocks (block size four to six [two to four for men]), stratified by primary health centre and sex, and allocation was concealed with use of sequential numbered opaque envelopes. Physicians providing EUC were masked. Primary outcomes were depression symptom severity on the Beck Depression Inventory version II and remission from depression (PHQ-9 score of <10) at 3 months in the intention-to-treat population, assessed by masked field researchers. Secondary outcomes were disability, days unable to work, behavioural activation, suicidal thoughts or attempts, intimate partner violence, and resource use and costs of illness. We assessed serious adverse events in the per-protocol population. This trial is registered with the ISRCTN registry, number ISRCTN95149997. Findings: Between Oct 28, 2013, and July 29, 2015, we enrolled and randomly allocated 495 participants (247 [50%] to the EUC plus HAP group [two of whom were subsequently excluded because of protocol violations] and 248 [50%] to the EUC alone group), of whom 466 (95%) completed the 3 month primary outcome assessment (230 [49%] in the EUC plus HAP group and 236 [51%] in the EUC alone group). Participants in the EUC plus HAP group had significantly lower symptom severity (Beck Depression Inventory version II in EUC plus HAP group 19·99 [SD 15·70] vs 27·52 [13·26] in EUC alone group; adjusted mean difference -7·57 [95% CI -10·27 to -4·86]; p<0·0001) and higher remission (147 [64%] of 230 had a PHQ-9 score of <10 in the HAP plus EUC group vs 91 [39%] of 236 in the EUC alone group; adjusted prevalence ratio 1·61 [1·34-1·93]) than did those in the EUC alone group. EUC plus HAP showed better results than did EUC alone for the secondary outcomes of disability (adjusted mean difference -2·73 [-4·39 to -1·06]; p=0·001), days out of work (-2·29 [-3·84 to -0·73]; p=0·004), intimate partner physical violence in women (0·53 [0·29-0·96]; p=0·04), behavioural activation (2·17 [1·34-3·00]; p<0·0001), and suicidal thoughts or attempts (0·61 [0·45-0·83]; p=0·001). The incremental cost per quality-adjusted life-year gained was $9333 (95% CI 3862-28 169; 2015 international dollars), with an 87% chance of being cost-effective in the study setting. Serious adverse events were infrequent and similar between groups (nine [4%] in the EUC plus HAP group vs ten [4%] in the EUC alone group; p=1·00). Interpretation: HAP delivered by lay counsellors plus EUC was better than EUC alone was for patients with moderately severe to severe depression in routine primary care in Goa, India. HAP was readily accepted by this previously untreated population and was cost-effective in this setting. HAP could be a key strategy to reduce the treatment gap for depressive disorders, the leading mental health disorder worldwide. Funding: Wellcome Trust.

Towards universal voluntary HIV testing and counselling: a systematic review and meta-analysis of community-based approaches.

Background: Effective national and global HIV responses require a significant expansion of HIV testing and counselling (HTC) to expand access to prevention and care. Facility-based HTC, while essential, is unlikely to meet national and global targets on its own. This article systematically reviews the evidence for community-based HTC. Methods and findings: PubMed was searched on 4 March 2013, clinical trial registries were searched on 3 September 2012, and Embase and the World Health Organization Global Index Medicus were searched on 10 April 2012 for studies including community-based HTC (i.e., HTC outside of health facilities). Randomised controlled trials, and observational studies were eligible if they included a community-based testing approach and reported one or more of the following outcomes: uptake, proportion receiving their first HIV test, CD4 value at diagnosis, linkage to care, HIV positivity rate, HTC coverage, HIV incidence, or cost per person tested (outcomes are defined fully in the text). The following community-based HTC approaches were reviewed: (1) door-to-door testing (systematically offering HTC to homes in a catchment area), (2) mobile testing for the general population (offering HTC via a mobile HTC service), (3) index testing (offering HTC to household members of people with HIV and persons who may have been exposed to HIV), (4) mobile testing for men who have sex with men, (5) mobile testing for people who inject drugs, (6) mobile testing for female sex workers, (7) mobile testing for adolescents, (8) self-testing, (9) workplace HTC, (10) church-based HTC, and (11) school-based HTC. The Newcastle-Ottawa Quality Assessment Scale and the Cochrane Collaboration's "risk of bias" tool were used to assess the risk of bias in studies with a comparator arm included in pooled estimates. 117 studies, including 864,651 participants completing HTC, met the inclusion criteria. The percentage of people offered community-based HTC who accepted HTC was as follows: index testing, 88% of 12,052 participants; self-testing, 87% of 1,839 participants; mobile testing, 87% of 79,475 participants; door-to-door testing, 80% of 555,267 participants; workplace testing, 67% of 62,406 participants; and school-based testing, 62% of 2,593 participants. Mobile HTC uptake among key populations (men who have sex with men, people who inject drugs, female sex workers, and adolescents) ranged from 9% to 100% (among 41,110 participants across studies), with heterogeneity related to how testing was offered. Community-based approaches increased HTC uptake (relative risk [RR] 10.65, 95% confidence interval [CI] 6.27-18.08), the proportion of first-time testers (RR 1.23, 95% CI 1.06-1.42), and the proportion of participants with CD4 counts above 350 cells/µl (RR 1.42, 95% CI 1.16-1.74), and obtained a lower positivity rate (RR 0.59, 95% CI 0.37-0.96), relative to facility-based approaches. 80% (95% CI 75%-85%) of 5,832 community-based HTC participants obtained a CD4 measurement following HIV diagnosis, and 73% (95% CI 61%-85%) of 527 community-based HTC participants initiated antiretroviral therapy following a CD4 measurement indicating eligibility. The data on linking participants without HIV to prevention services were limited. In low- and middle-income countries, the cost per person tested ranged from US$2-US$126. At the population level, community-based HTC increased HTC coverage (RR 7.07, 95% CI 3.52-14.22) and reduced HIV incidence (RR 0.86, 95% CI 0.73-1.02), although the incidence reduction lacked statistical significance. No studies reported any harm arising as a result of having been tested. Conclusions: Community-based HTC achieved high rates of HTC uptake, reached people with high CD4 counts, and linked people to care. It also obtained a lower HIV positivity rate relative to facility-based approaches. Further research is needed to further improve acceptability of community-based HTC for key populations. HIV programmes should offer community-based HTC linked to prevention and care, in addition to facility-based HTC, to support increased access to HIV prevention, care, and treatment.

A pilot randomized trial of community-based parent training for immigrant Latina mothers.

This paper reports on the development and piloting of the Madres a Madres (Mothers to Mothers) program, a new, community-based parent training program designed for immigrant Latina mothers and their children. Promotoras, or female community health workers of Latina background, delivered the program in a home visitation format. A total of 194 mothers and 194 focal children (87 male, 107 female) ages 7-12 were randomized to the intervention (113 mother-child dyads) or wait-list control condition (81 mother-child dyads) over the study period. Outcomes of interest were mother-reported parenting skills, broad family functioning, and child externalizing and internalizing behaviors. Data collection occurred at pretest, 3-month posttest, and 9-month follow-up periods. Multilevel growth models revealed increases in intervention mothers' reported parenting skills, family support, and family organization, and reductions in child internalizing behavior from pretest to follow-up, relative to the control condition. Outcomes did not vary by focal child age, gender, nativity status, or mother acculturative status (years in the United States). Findings are discussed in the context of future directions for research on the Madres a Madres program and on the implementation and dissemination of empirically-supported parent training practices to culturally diverse families.

Maintenance treatment with varenicline for smoking cessation in patients with schizophrenia and bipolar disorder: a randomized clinical trial.

Importance: It is estimated that more than half of those with serious mental illness smoke tobacco regularly. Standard courses of pharmacotherapeutic cessation aids improve short-term abstinence, but most who attain abstinence relapse rapidly after discontinuation of pharmacotherapy. Objective: To determine whether smokers diagnosed with schizophrenia and bipolar disease have higher rates of prolonged tobacco abstinence with maintenance pharmacotherapy than with standard treatment. Design, setting, and participants: Randomized, double-blind, placebo-controlled, parallel-group, relapse-prevention clinical trial conducted in 10 community mental-health centers. Of 247 smokers with schizophrenia or bipolar disease recruited from March 2008-April 2012, 203 received 12-weeks' open-label varenicline and cognitive behavioral therapy and 87 met abstinence criteria to enter the relapse prevention intervention. Interventions: Participants who had 2 weeks or more of continuous abstinence at week 12 of open treatment were randomly assigned to receive cognitive behavioral therapy and double-blind varenicline (1 mg, 2 per day) or placebo from weeks 12 to 52. Participants then discontinued study treatment and were followed up to week 76. Main outcomes and measures: Seven-day rate of continuous abstinence at study week 52, the end of the relapse-prevention phase, confirmed by exhaled carbon monoxide. Secondary outcomes were continuous abstinence rates for weeks 12 through 64 based on biochemically verified abstinence and weeks 12 through 76, based on self-reported smoking behavior. Results: Sixty-one participants completed the relapse-prevention phase; 26 discontinued participation (7 varenicline, 19 placebo) and were considered to have relapsed for the analyses; 18 of these had relapsed prior to dropout. At week 52, point-prevalence abstinence rates were 60% in the varenicline group (24 of 40) vs 19% (9 of 47) in the placebo group (odds ratio [OR], 6.2; 95% CI, 2.2-19.2; P < .001). From weeks 12 through 64, 45% (18 of 40) among those in the varenicline group vs 15% (7 of 47) in the placebo group were continuously abstinent (OR, 4.6; 95% CI, 1.5-15.7; P = .004), and from weeks 12 through 76, 30% (12 of 40) in the varenicline group vs 11% (5 of 47) in the placebo group were continuously abstinent (OR, 3.4; 95% CI, 1.02-13.6; P = .03). There were no significant treatment effects on psychiatric symptom ratings or psychiatric adverse events. Conclusions and relevance: Among smokers with serious mental illness who attained initial abstinence with standard treatment, maintenance pharmacotherapy with varenicline and cognitive behavioral therapy improved prolonged tobacco abstinence rates compared with cognitive behavioral therapy alone after 1 year of treatment and at 6 months after treatment discontinuation.

Long-term quality-of-life outcomes after radical prostatectomy or watchful waiting: the Scandinavian Prostate Cancer Group-4 randomised trial.

Background: For men with localised prostate cancer, surgery provides a survival benefit compared with watchful waiting. Treatments are associated with morbidity. Results for functional outcome and quality of life are rarely reported beyond 10 years and are lacking from randomised settings. We report results for quality of life for men in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) after a median follow-up of more than 12 years. Methods: All living Swedish and Finnish men (400 of 695) randomly assigned to radical prostatectomy or watchful waiting in SPCG-4 from 1989 to 1999 were included in our analysis. An additional 281 men were included in a population-based control group matched for region and age. Physical symptoms, symptom-induced stress, and self-assessed quality of life were evaluated with a study-specific questionnaire. Longitudinal data were available for 166 Swedish men who had answered quality-of-life questionnaires at an earlier timepoint. Findings: 182 (88%) of 208 men in the radical prostatectomy group, 167 (87%) of 192 men in the watchful-waiting group, and 214 (76%) of 281 men in the population-based control group answered the questionnaire. Men in SPCG-4 had a median follow-up of 12·2 years (range 7-17) and a median age of 77·0 years (range 61-88). High self-assessed quality of life was reported by 62 (35%) of 179 men allocated radical prostatectomy, 55 (34%) of 160 men assigned to watchful waiting, and 93 (45%) of 208 men in the control group. Anxiety was higher in the SPCG-4 groups (77 [43%] of 178 and 69 [43%] of 161 men) than in the control group (68 [33%] of 208 men; relative risk 1·42, 95% CI 1·07-1·88). Prevalence of erectile dysfunction was 84% (146 of 173 men) in the radical prostatectomy group, 80% (122 of 153) in the watchful-waiting group, and 46% (95 of 208) in the control group and prevalence of urinary leakage was 41% (71 of 173), 11% (18 of 164), and 3% (six of 209), respectively. Distress caused by these symptoms was reported significantly more often by men allocated radical prostatectomy than by men assigned to watchful waiting. In a longitudinal analysis of men in SPCG-4 who provided information at two follow-up points 9 years apart, 38 (45%) of 85 men allocated radical prostatectomy and 48 (60%) of 80 men allocated watchful waiting reported an increase in number of physical symptoms; 50 (61%) of 82 and 47 (64%) of 74 men, respectively, reported a reduction in quality of life. Interpretation: For men in SPCG-4, negative side-effects were common and added more stress than was reported in the control population. In the radical prostatectomy group, erectile dysfunction and urinary leakage were often consequences of surgery. In the watchful-waiting group, side-effects can be caused by tumour progression. The number and severity of side-effects changes over time at a higher rate than is caused by normal ageing and a loss of sexual ability is a persistent psychological problem for both interventions. An understanding of the patterns of side-effects and time dimension of their occurrence for each treatment is important for full patient information.

Effect of nightly versus on-demand vardenafil on recovery of erectile function in men following bilateral nerve-sparing radical prostatectomy.

Background: To date, no data have been available from large, well-designed trials comparing on demand and nightly dosing of phosphodiesterase type 5 (PDE5) inhibitors on recovery of erectile function in postprostatectomy patients with erectile dysfunction (ED). Objective: To investigate the effect of early postoperative dosing with vardenafil, administered either nightly or on demand, compared with placebo on recovery of erectile function in men with ED following bilateral nerve-sparing radical prostatectomy (NSRP) surgery. Design, setting, and participants: A randomised, double-blind, double-dummy, multicentre, parallel group study conducted at 87 centres across Europe, Canada, South Africa, and the United States. For inclusion, patients had to be scheduled to undergo bilateral NSRP within 1 mo of screening and have a normal International Index of Erectile Function erectile function domain (IIEF-EF) score of > or =26 at screening. A total of 628 men, aged 18-64 yr, were randomised to treatment. Study design consisted of a 9-mo double-blind treatment period, a 2-mo single-blind washout period, and an optional 2-mo open-label period. Intervention: Patients received placebo, nightly vardenafil, or on demand vardenafil. Measurements: Primary outcome measure was the percentage of subjects with an IIEF-EF score of > or =22 after the 2-mo washout period. Secondary variables included mean per-patient success rates for Sexual Encounter Profile (SEP) questions 2 and 3. Results and limitations: No statistically significant differences were observed among treatment groups in the proportion of patients with an IIEF-EF score of > or =22 or in SEP3 success rates after the washout period. On-demand vardenafil treatment resulted in significantly greater IIEF-EF scores and better SEP3 response rates than placebo over the entire treatment period. Conclusions: In this study of men with ED following bilateral NSRP, vardenafil was efficacious when used on demand, supporting a paradigm shift towards on demand dosing with PDE5 inhibitors in this patient group.

Risk Factors, Imaging Findings, and Sex Differences in Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection (SCAD) is increasingly being recognized. However, data supporting diagnosis and management are scarce. We analyze a contemporary and comprehensive SCAD registry to advance the understanding of SCAD risk factors, angiographic appearance, and gender differences. This is a retrospective analysis of a prospectively populated database of SCAD patients seen at the Massachusetts General Hospital (MGH) between June 2013 and October 2017. Core laboratory analysis of both coronary angiograms and computerized tomographic (CT) angiography of the extracoronary vessels was performed. Of the 113 patients, 87% were female and mean age was 47 ± 10 years. Traditional cardiovascular risk factors including hypertension, hyperlipidemia, and smoking were present in 27%, 14%, and 22% of patients. Among females, 14%, 8%, and 9% had a history of gestational hypertension, pre-eclampsia, and gestational diabetes, respectively. Fifteen percent had used fertility treatment and 47% of postmenopausal women had used hormone replacement therapy. Angiography showed multivessel SCAD in 42%, severe coronary artery tortuosity in 59%, and extracoronary vascular abnormalities in 100% of patients with complete CT angiographic imaging. Gender differences revealed a self-reported depression and anxiety prevalence of 20% and 32%, respectively, in women compared with 0% in men. Type 1 SCAD was more commonly diagnosed in men than women (71% vs 29%, p <0.01). In conclusion, we highlight under-recognized features of SCAD including (1) relation with pregnancy complications and exposure to hormonal therapy; (2) diffuse, multivessel process in tortuous coronaries on a background of extracoronary arterial abnormalities; and (3) gender differences highlighting the role of mental health as well as potential underdiagnoses in men.

The epidemiology of trauma and post-traumatic stress disorder in a representative cohort of young people in England and Wales.

Background: Despite the emphasis placed on childhood trauma in psychiatry, comparatively little is known about the epidemiology of trauma and trauma-related psychopathology in young people. We therefore aimed to evaluate the prevalence, clinical features, and risk factors associated with trauma exposure and post-traumatic stress disorder (PTSD) in young people. Methods: We carried out a comprehensive epidemiological study based on participants from the Environmental Risk Longitudinal Twin Study, a population-representative birth-cohort of 2232 children born in England and Wales in 1994-95. At the follow-up home visit at age 18 years, participants were assessed with structured interviews for trauma exposure, PTSD, other psychopathology, risk events, functional impairment, and service use. Risk factors for PTSD were measured prospectively over four previous assessments between age 5 and 12 years. The key outcomes were the prevalence, clinical features, and risk factors associated with trauma exposure and PTSD. We also derived and tested the internal validity of a PTSD risk calculator. Findings: We found that 642 (31·1%) of 2064 participants reported trauma exposure and 160 (7·8%) of 2063 experienced PTSD by age 18 years. Trauma-exposed participants had high rates of psychopathology (187 [29·2%] of 641 for major depressive episode, 146 [22·9%] of 638 for conduct disorder, and 102 [15·9%] of 641 for alcohol dependence), risk events (160 [25·0%] of 641 for self-harm, 53 [8·3%] of 640 for suicide attempt, and 42 [6·6%] of 640 for violent offence), and functional impairment. Participants with lifetime PTSD had even higher rates of psychopathology (87 [54·7%] of 159 for major depressive episode, 43 [27·0%] of 159 for conduct disorder, and 41 [25·6%] of 160 for alcohol dependence), risk events (78 [48·8%] of 160 for self-harm, 32 [20·1%] of 159 for suicide attempt, and 19 [11·9%] of 159 for violent offence), and functional impairment. However, only 33 (20·6%) of 160 participants with PTSD received help from mental health professionals. The PTSD risk calculator had an internally validated area under the receiver operating characteristic curve of 0·74, indicating adequate discrimination of trauma-exposed participants with and without PTSD, and internally validated calibration-in-the-large of -0·10 and calibration slope of 0·90, indicating adequate calibration. Interpretation: Trauma exposure and PTSD are associated with complex psychiatric presentations, high risk, and significant impairment in young people. Improved screening, reduced barriers to care provision, and comprehensive clinical assessment are needed to ensure that trauma-exposed young people and those with PTSD receive appropriate treatment.

Are secondary data sources on the neighbourhood food environment accurate? Case-study in Glasgow, UK.

Objectives: To assess the validity of a publicly available list of food stores through field observations of their existence, in order to contribute to research on neighbourhood food environments and health. Methods: All multiple-owned supermarkets, and a 1 in 8 sample of other food outlets, listed in 1997 and 2007 in the public register of food premises held by Glasgow City Council, Scotland, were visited to establish whether they were trading as foodstores. Postcode sectors in which foodstores were located were classified into least, middling and most deprived neighbourhoods. Results: In total, 325 listed foodstores were visited in 1997 and 508 in 2007. Of these 87% and 88%, respectively, were trading as foodstores. There was a very slight gradient in validity by deprivation, with validity higher in least deprived neighbourhoods, though this was not statistically significant. Conclusions: There was reasonable, but not perfect, agreement between the list of food premises and field observations, with nearly 1 in 9 of sampled foodstores not present on the ground. Since the use of inaccurate secondary data sources may affect estimates of relationships between the neighbourhood food environment and health, further work is required to establish the validity of such data in different contexts.

An update on hepatitis C virus genotype distribution in Jordan: a 12-year retrospective study from a tertiary care teaching hospital in Amman.

Background: Nucleic acid hybridization (NAH) of hepatitis C virus (HCV) is a practical and reliable tool for virus genotyping. Genotype assignment is an important factor in the prediction of treatment success in chronic hepatitis C patients. The aim of this study was to determine the genotype distribution among HCV clinical isolates in Jordan between 2007 and 2018. Methods: Electronic and paper-based clinical data registry records from 2007 to 2018 at the Jordan University Hospital (JUH) were retrospectively examined for individuals with HCV genotype, HCV viral load, and alanine aminotransferase (ALT) testing results. Genotype determination was based on NAH technique using the HCV 5' untranslated region (5' UTR) with 386 requests available from 342 unique individuals. Results: A total of 263 out of 342 unique individuals (76.9%) had genotyping results available for final analysis with 259 individuals each having a single genotyping result. The most common HCV genotypes in the study were: genotype 4 (n = 142, 54.0%), genotype 1 (n = 87, 33.1%), genotype 3 (n = 16, 6.1%), genotype 2 (n = 9, 3.4%), other undetermined genotypes (n = 5, 1.9%) and mixed infections (n = 4, 1.5%). Sub-genotyping results were available for 46 individuals as follows: sub-genotype 4c/d (n = 13, 28.3%), sub-genotype 1a (n = 11, 23.9%), sub-genotype 1b (n = 10, 21.7%), sub-genotype 4a (n = 8, 17.4%), sub-genotype 3a (n = 2, 4.3%), sub-genotypes 2a/c and 4 h (n = 1, 2.2% for both). Individuals infected with genotype 1 showed higher viral load when compared to those infected with genotype 4 (p = 0.048, t-test). Younger HCV-infected individuals (< 52 years) had higher ALT levels compared to older individuals (p = 0.036, t-test). Self-reported risk factors for HCV acquisition included: history of previous surgery, invasive dental procedures, and blood transfusion, delivery at home, circumcision at home and wet cupping therapy (hijama). Conclusions: High genetic diversity of HCV was found in Jordan, with genotypes 4 and 1 as the most prevalent genotypes co-circulating in the country. Potential impact of virus genotype on disease markers (viral load, ALT) was detected and needs further assessment. The study can be helpful to plan for future prevention and management of HCV infection in Jordan.

Cognitive and psychiatric symptom trajectories 2-3 years after hospital admission for COVID-19: a longitudinal, prospective cohort study in the UK.

Background: COVID-19 is known to be associated with increased risks of cognitive and psychiatric outcomes after the acute phase of disease. We aimed to assess whether these symptoms can emerge or persist more than 1 year after hospitalisation for COVID-19, to identify which early aspects of COVID-19 illness predict longer-term symptoms, and to establish how these symptoms relate to occupational functioning. Methods: The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study of adults (aged ≥18 years) who were hospitalised with a clinical diagnosis of COVID-19 at participating National Health Service hospitals across the UK. In the C-Fog study, a subset of PHOSP-COVID participants who consented to be recontacted for other research were invited to complete a computerised cognitive assessment and clinical scales between 2 years and 3 years after hospital admission. Participants completed eight cognitive tasks, covering eight cognitive domains, from the Cognitron battery, in addition to the 9-item Patient Health Questionnaire for depression, the Generalised Anxiety Disorder 7-item scale, the Functional Assessment of Chronic Illness Therapy Fatigue Scale, and the 20-item Cognitive Change Index (CCI-20) questionnaire to assess subjective cognitive decline. We evaluated how the absolute risks of symptoms evolved between follow-ups at 6 months, 12 months, and 2-3 years, and whether symptoms at 2-3 years were predicted by earlier aspects of COVID-19 illness. Participants completed an occupation change questionnaire to establish whether their occupation or working status had changed and, if so, why. We assessed which symptoms at 2-3 years were associated with occupation change. People with lived experience were involved in the study. Findings: 2469 PHOSP-COVID participants were invited to participate in the C-Fog study, and 475 participants (191 [40·2%] females and 284 [59·8%] males; mean age 58·26 [SD 11·13] years) who were discharged from one of 83 hospitals provided data at the 2-3-year follow-up. Participants had worse cognitive scores than would be expected on the basis of their sociodemographic characteristics across all cognitive domains tested (average score 0·71 SD below the mean [IQR 0·16-1·04]; p<0·0001). Most participants reported at least mild depression (263 [74·5%] of 353), anxiety (189 [53·5%] of 353), fatigue (220 [62·3%] of 353), or subjective cognitive decline (184 [52·1%] of 353), and more than a fifth reported severe depression (79 [22·4%] of 353), fatigue (87 [24·6%] of 353), or subjective cognitive decline (88 [24·9%] of 353). Depression, anxiety, and fatigue were worse at 2-3 years than at 6 months or 12 months, with evidence of both worsening of existing symptoms and emergence of new symptoms. Symptoms at 2-3 years were not predicted by the severity of acute COVID-19 illness, but were strongly predicted by the degree of recovery at 6 months (explaining 35·0-48·8% of the variance in anxiety, depression, fatigue, and subjective cognitive decline); by a biocognitive profile linking acutely raised D-dimer relative to C-reactive protein with subjective cognitive deficits at 6 months (explaining 7·0-17·2% of the variance in anxiety, depression, fatigue, and subjective cognitive decline); and by anxiety, depression, fatigue, and subjective cognitive deficit at 6 months. Objective cognitive deficits at 2-3 years were not predicted by any of the factors tested, except for cognitive deficits at 6 months, explaining 10·6% of their variance. 95 of 353 participants (26·9% [95% CI 22·6-31·8]) reported occupational change, with poor health being the most common reason for this change. Occupation change was strongly and specifically associated with objective cognitive deficits (odds ratio [OR] 1·51 [95% CI 1·04-2·22] for every SD decrease in overall cognitive score) and subjective cognitive decline (OR 1·54 [1·21-1·98] for every point increase in CCI-20). Interpretation: Psychiatric and cognitive symptoms appear to increase over the first 2-3 years post-hospitalisation due to both worsening of symptoms already present at 6 months and emergence of new symptoms. New symptoms occur mostly in people with other symptoms already present at 6 months. Early identification and management of symptoms might therefore be an effective strategy to prevent later onset of a complex syndrome. Occupation change is common and associated mainly with objective and subjective cognitive deficits. Interventions to promote cognitive recovery or to prevent cognitive decline are therefore needed to limit the functional and economic impacts of COVID-19.

Lipid signaling: sleep, synaptic plasticity, and neuroprotection.

Increasing evidence indicates that bioactive lipids participate in the regulation of synaptic function and dysfunction. We have demonstrated that signaling mediated by platelet-activating factor (PAF) and cyclooxygenase (COX)-2-synthesized PGE2 is involved in synaptic plasticity, memory, and neuronal protection [Clark GD, Happel LT, Zorumski CF, Bazan NG. Enhancement of hippocampal excitatory synaptic transmission by platelet-activating factor. Neuron 1992; 9:1211; Kato K, Clark GD, Bazan NG, Zorumski CF. Platelet-activating factor as a potential retrograde messenger in CA1 hippocampal long-term potentiation. Nature 1994; 367:175; Izquierdo I, Fin C, Schmitz PK, et al. Memory enhancement by intrahippocampal, intraamygdala or intraentorhinal infusion of platelet-activating factor measured in an inhibitory avoidance. Proc Natl Acad Sci USA 1995; 92:5047; Chen C, Magee CJ, Bazan NG. Cyclooxygenase-2 regulates prostaglandin E2 signaling in hippocampal long-term synaptic plasticity. J Neurophysiol 2002; 87:2851]. Recently, we found that prolonged continuous wakefulness (primarily rapid eye movement (REM)-sleep deprivation, SD) causes impairments in hippocampal long-term synaptic plasticity and hippocampus-dependent memory formation [McDermott CM, LaHoste GJ, Chen C, Musto A, Bazan NG, Magee JC. Sleep deprivation causes behavioral, synaptic, and membrane excitability alterations in hippocampal neurons. J Neurosci 2003; 23:9687]. To explore the mechanisms underlying SD-induced impairments, we have studied several bioactive lipids in the hippocampus following SD. It appears that SD causes increases in prostaglandin D2 (PGD2) and 2-arachidonylglycerol (2-AG), and a decrease in PGE2, suggesting that these lipid messengers participate in memory consolidation during REM sleep. We have also explored the formation of endogenous neuroprotective lipids. Toward this aim, we have used ischemia-reperfusion damage and LC-PDA-ESI-MS-MS-based lipidomic analysis and identified docosanoids derived from synaptic phospholipid-enriched docosahexaenoic acid.

Taken together, these observations that signaling lipids participate in synaptic plasticity, cognition, and survival indicate that lipid signaling is closely associated with several functions (e.g; learning and memory, sleep, and experimental stroke) and pathologic events. Alterations in endogenous signaling lipids or their receptors resulting from drug abuse lead to changes in synaptic circuitry and induce profound effects on these important functions. In the present article, we will briefly review bioactive lipids involved in sleep, synaptic transmission and plasticity, and neuroprotection, focusing mainly on our experimental studies and how these signaling molecules are related to functions and implicated in some neurologic disorders.

Patients with asthma have an underlying chronic inflammation of the airways characterized by activated mast cells, eosinophils, and T-helper 2 lymphocytes. This results in increased responsiveness of the airways to such triggers as exercise, allergens, and air pollutants. This chronic inflammation underlies the typical symptoms of asthma, which include intermittent wheezing, coughing, shortness of breath, and chest tightness. Corticosteroids are the most effective treatment for asthma, and inhaled corticosteroids have become first-line treatment for children and adults with persistent symptoms. Corticosteroids suppress the chronic airway inflammation in patients with asthma, and the molecular ...References1. Busse WW, Lemanske RF. Asthma. N Engl J Med. 2001;344:350-62.

"There Was a Sense That Our Load Had Been Lightened": Evaluating Outcomes of Virtual Ethics Rounds for Veterinary Team Members.

Clinical ethics support services (CESS) are employed in healthcare to improve patient care and help team members develop skills to recognize and navigate ethically challenging situations (ECS). The objective of this study was to evaluate the impact of ethics rounds, one form of CESS, on veterinary team members. An anonymous, online mixed-methods survey incorporating a 15-item instrument designed to assess the outcomes of moral case deliberation originally developed for human healthcare workers (the Euro-MCD 2.0), was developed. The survey was administered to veterinary team members prior to and following participation in a 90-min virtual ethics rounds session. A total of 23 sessions of virtual ethics rounds were held. In total, 213 individuals participated, and 89 completed both surveys (response rate 41.8%). Most respondents were female (n = 70, 81%). Most were veterinarians (n = 51, 59%), followed by other veterinary team members (practice manager, animal attendant) (n = 18, 21%), veterinary nurses or animal health technicians (n = 10, 12%) and veterinary students (n = 8, 9%). Age ranged from 20 to 73 (median 41, IQR 32-52, n = 87). While there was no statistically significant difference between overall modified Euro-MCD 2.0 scores between T1 and T2, there were statistically significant changes in 7 out of 15 Euro-MCD 2.0 items in the domains of moral competence and moral teamwork. Reflexive thematic analysis of free-text responses identified themes including the types, impact and barriers to resolving ECS, the impacts of ethics rounds on veterinary team members and constraints preventing veterinary team members from speaking up in the face of ECS. While participants largely described the impact of ethics rounds as beneficial (for example, by facilitating clarification of thinking about ECS, allowing participants to see ECS from the perspective of others and providing a safe space for discussion), reflecting on ECS could be stressful for participants. Active participation in ethics rounds may be inhibited in the context of power imbalance, or in settings where bullying occurs. Overall, carefully facilitated ethics rounds has the potential to improve the ability of veterinary team members to identify and navigate ECS, and potentially mitigate moral distress.

Quality of delivery of "right@home": Implementation evaluation of an Australian sustained nurse home visiting intervention to improve parenting and the home learning environment.

Background: Home visiting programs are implemented in high income countries to improve outcomes for families with young children. Significant resources are invested in such programs and high quality evaluations are important. In the context of research trials, implementation quality is often poorly reported and, when reported, is variable. This paper presents the quality of implementation of the right@home program, a sustained nurse home visiting intervention trialled in Australia, and delivered in a 'real world' context through usual child and family health services. right@home is structured around the core Maternal Early Childhood Sustained Home-visiting (MECSH) program, which is a salutogenic, child focused prevention model. Method: At each visit right@home practitioners completed a checklist detailing the client unique identifier, date of contact and activities undertaken. These checklists were collated to provide data on intervention dose, retention to program completion at child age 2 years, and visit content, which were compared with the program schedule. Quality of family-provider relationship was measured using the Session Rating Scale. Exploratory factor analysis was conducted to identify clusters of activities and allow qualitative assessment of concordance between program aims and program delivery. Results: Of 363 intervention families offered the program, 352 (97·0%) commenced the program and 304 (87·3%) completed the program to child age 2 years. 253 of 352 (71·9%) families who commenced the program received more than 75 percent of scheduled visits including at least one antenatal visit. Families rated the participant-practitioner relationship highly (mean 39.4/40). The factor analysis identified six antenatal and six postnatal components which were concordant with the program aims. Conclusions: The right@home program was delivered with higher adherence to program dose, schedule and content, and retention than usually reported in other home visiting research. Program compliance may have resulted from program design (visit schedule, dose, content and delivery flexibility) that was consistent with family aims.

Better members of society? In her recent article, 'Pleasure junkies all around! Why it matters and why "the arts" might be the answer: a biopsychological perspective', Christensen [1] claims that engaging with art can promote healthy choices, choices that balance short-term pleasure goals with long-term general well-being. She suggests that many modern life conveniences, such as social media, computer games or online shopping, have the potential to turn us into 'pleasure junkies' because they maximize short-term pleasures. But art, Christensen argues, is a safe choice and a means to remedy this unhealthy addiction to pleasure. Christensen's argument is grounded on three claims about the sort of pleasure we get from art. First, in contrast to low-level pleasure, which Christensen conceives as 'a mere perceptual stimulation leading to a rewarding sensation (food, sex, etc.)' ([1], p. 2), pleasure from art is presented as a kind of higher-order pleasure that engages 'broader neural networks implied in the attribution of meaning' (p. 2), presumably leading to 'long-term maintenance of healthy bodily function' (p. 2). Second, 'the arts do not induce states of craving without fulfilment—as do activities with reinforcement schedules which are prone to create habits and addictions such as intermittent variable ratio or interval reinforcement schedules (e.g. social media, gambling, football, extreme sports, drugs' (p. 4). Third, 'the arts do not search for a perceptual "Bliss point" […]. They do not just repeat over and over again a sensory stimulus that excites the senses and induces craving for more of a "pleasurable itch" (e.g. sugar, sexualized body displays, certain musical lyrics, tones; i.e. a perceptual "bliss point")' (p. 4).The claim, in a nutshell, is that the pleasure induced by art is different to the pleasure induced by food, sex, sports or drugs, because it is related to the balanced activation of brain systems related to short-term pleasure and long-term wellbeing goals, because it does not induce craving, and because it is not aimed at a perceptual 'bliss point'. This distinct sort of pleasure, according to Christensen, makes it possible for the arts to thwart the pernicious effects that the unhealthy urges and cravings licensed by 'today's mainstream acceptance of pleasure-seeking behaviour' (p. 5) have on individuals' lives and on societies. Such sweeping statements about art, food, sex, sports and society as a whole merit close examination. Christensen's primary claim that the pleasure induced by art is of a special kind, different to the pleasure induced by other activities is not supported by current understanding of what pleasure is. It is, moreover, contradicted by abundant empirical evidence. This evidence shows that pleasures, whatever their source, owe to activity in the same mesocorticolimbic circuit [2] and are encoded as a common neural currency [3]. As Kent Berridge and Morten Kringelbach put it: 'the brain mechanisms involved in fundamental pleasures (food and sexual pleasures) overlap with those for higher-order pleasures (e.g. monetary, artistic, musical, altruistic and transcendent pleasures) […] From sensory pleasures and drugs of abuse […] to monetary, aesthetic and musical delights, all pleasures seem to involve the same hedonic brain systems' ([4], p. 481). Thus, there is no evidence for specific brain regions or neural circuits related to the pleasure from art. Rather, the appreciation of art relies on brain mechanisms that evolved to appraise the value of biologically relevant objects in relation to internal homeostatic states [5]: 'Emotional reactions to music, further, activate the same cortical, subcortical and autonomic circuits, which are considered as the essential survival circuits of biological organisms in general' ([6], p. 6). In sum, the evidence shows that pleasure elicited by music and other art forms is no different in genesis and function to the pleasure induced by food, drugs and sex [7,8]. This is a matter of fact, not opinion. What supports Christensen's argument if not empirical evidence? In our view, her argument for the distinctness of art-induced pleasure seems based upon an oversimplified and devaluing conception of the pleasures of sex, food and sports, and a very narrow notion of art and its function. Christensen presents food, sex and sports as meaningless low-level sources of pleasure, and the arts as privileged vehicles for meaningful experiences. It is the personal and meaningful engagement with art—Christensen suggests—that fosters a balanced activation of brain systems related to short-term pleasure and long-term well-being goals. However, rarely—if ever—are food, sex and sports meaningless rewarding sensations. Contrary to Christensen's definition on page 2 of her article, pleasure—even sensory pleasure—is not simply reward, and never simply a sensation [4]. Indulging in food, sex or sports are meaningful and personally significant experiences that are not a matter of mere physical sensation. The experience of pleasure from food and sex is shaped by context, knowledge, expectations, anticipations, attitudes and beliefs that bring meaning to them [9–11]. Sex can be meaningful because it signifies physical connection with one's loved one, because it is cheating on someone, or deemed a sin. Likewise, eating is not about obtaining low-level pleasure. What we eat, the way we eat, what we believe about what we eat, where and whom we eat with, imbue eating with individual and social meaning, and shape the actual pleasure of eating [12]. On the other hand, encounters with art are not necessarily meaningful [13,14]. Actually, there is nothing intrinsically meaningful about engaging with art. Many laypeople lack the knowledge schemata required to engage meaningfully with abstract, cubist or contemporary art [15,16]. There are plenty of artworks people do not find meaningful or pleasant. Meaning making is not a special feature of art; it is a general feature of our species's cognition [17,18]. We can endow virtually any aspect of reality with meaning: sex, food, sports, a urinal, the shape of a cloud, an averted glance, someone's absence. Christensen's argument also rests on a historically and culturally narrow conception of art and its function. Art is presented as a circumscribed category of activities that elicit a unique sort of pleasant experiences: — The arts are set of activities of a special kind that share certain defining features distinguishing them from other activities: 'the arts push boundaries, surprise, reveal and excite both artist and spectator' ([1], p. 4).— Art encounters are positive, leading to 'pleasurable chills' and pleasurable experiences of understanding: 'The moment of meaning-assignation, also called "mastering" or "understanding" an artwork, is therefore a pleasurable experience' ([1], p. 4).— The pleasure elicited by art is special, because it does not involve craving for intense peaks: 'The arts do not search for a perceptual "bliss point" […] They do not just repeat over and over a sensory stimulus that excites the senses and induces craving for more of a "pleasurable itch"' ([1], p. 4).This characterization of the arts substantially overlaps with the notion of 'fine arts'. The core features of this characterization were instituted in the eighteenth century, after European intellectuals grouped certain activities into a distinct and autonomous collection, labelled 'fine arts'. To make sense of and promote this grouping, it became imperative to identify a common essence setting art apart from other activities [19,20,21]. One of the most popular proposals was that only art could produce a special sort of pleasure, sophisticated and polite [19,21]—a conception stemming not from any understanding of physiology, but from mere speculation. This limited historical and cultural scope renders this conception of the arts unfit for behavioural or neuroscientific research [19]. The category 'the arts' should not be mistaken for a natural kind. It is a historical convention, and has no direct biological correspondence. Moreover, this conception of art that Christensen espouses does not apply to art as practised in non-Western societies [19,22]. It does not even apply to Western art before the eighteenth century or after the nineteenth century [19,20,21]. First, art does not necessarily evoke pleasurable experiences. There are abundant artworks intended to arouse negative emotions [19,23], and to portray physical and moral ugliness [24]. Understanding art is not necessarily a pleasant experience: it can be an angering, disgusting or upsetting one [25]. Second, many artworks actually exploit repetition, bliss points and craving [26]. Repetition is a fundamental design feature of music and other performance arts [27]: In Relation in Space (1976) Marina Abramovic and Ulay ran into each other repeatedly for an hour; Ravel's Bolero is a 17 min-long instance of melodic and rhythmic repetitiveness. Anticipation and craving for bliss points are also essential to music [28]. In fact, the enjoyment of music is linked to intense feelings of anticipation and expectation caused by dopamine activity in the caudate nucleus (also involved in the rewarding aspect of food) [29,30], and peak pleasure states (bliss points) [31], caused by the release of dopamine and opioids in the brain's reward system (also involved in cocaine induced euphoria) [29,30]. Given the available evidence, therefore, there is no reason to believe that the pleasure from art is special or unique [32].In sum, Christensen's claim for the distinctiveness of pleasure from art is contradicted by empirical evidence, and her argument for the beneficial effects of art rests upon disputed foundations. Art's capacity to promote healthier choices and make us better people that can contribute to a better society remains as unconfirmed today as it was when Schiller speculated on art's power to harmonize human's conflicting sensuous and formal impulses. Christensen's argument is problematic even if intended to highlight hypothetical possibilities. Arguments about hypothetical possibilities should still rely on valid premises, and scientific hypotheses should be grounded on evidence, or at least in line with it. Otherwise, they are merely unfounded speculations. Scientific aesthetics is only just finding its footing and its place within cognitive neuroscience [33,34]. If evidence is ignored or rejected because it does not fit preconceived notions about art and its function, scientific aesthetics will become only an arena to promote and legitimize personally appealing notions of art by applying a scientific gloss over them. A proper scientific study of art needs to be grounded on empirical evidence and strong arguments that follow from solid premises [35,36]. Only then can scientific aesthetics provide reliable explanations for artistic and aesthetic behaviour, and thus make a significant contribution to the understanding of our human nature.

AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY GUIDELINES FOR MANAGEMENT OF DYSLIPIDEMIA AND PREVENTION OF CARDIOVASCULAR DISEASE.

Objective: The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Methods: Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. Results: The Executive Summary of this document contains 87 recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 203 (29.2 %) are EL 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 236 (34.0%) are EL 4 (no clinical evidence). Conclusion: This CPG is a practical tool that endocrinologists, other health care professionals, health-related organizations, and regulatory bodies can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of individuals with various lipid disorders. The recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously endorsed and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk.

Prevalence of depressive disorders and treatment in China: a cross-sectional epidemiological study.

Background: In China, depressive disorders have been estimated to be the second leading cause of years lived with disability. However, nationally representative epidemiological data for depressive disorders, in particular use of mental health services by adults with these disorders, are unavailable in China. The present study, part of the China Mental Health Survey, 2012-15, aims to describe the socioeconomic characteristics and the use of mental health services in people with depressive disorders in China. Methods: The China Mental Health Survey was a cross-sectional epidemiological survey of mental disorders in a multistage clustered-area probability sample of adults of Chinese nationality (≥18 years) from 157 nationwide representative population-based disease surveillance points in 31 provinces across China. Trained investigators interviewed the participants with the Composite International Diagnostic Interview 3.0 to ascertain the presence of lifetime and 12-month depressive disorders according to DSM-IV criteria, including major depressive disorder, dysthymic disorder, and depressive disorder not otherwise specified. Participants with 12-month depressive disorders were asked whether they received any treatment for their emotional problems during the past 12 months and, if so, the specific types of treatment providers. The Sheehan Disability Scale (SDS) was used to assess impairments associated with 12-month depressive symptoms. Data-quality control procedures included logic check by computers, sequential recording check, and phone-call check by the quality controllers, and reinterview check by the psychiatrists. Data were weighted according to the age-sex-residence distribution data from China's 2010 census population survey to adjust for differential probabilities of selection and differential response, as well as to post-stratify the sample to match the population distribution. Findings: 28 140 respondents (12 537 [44·6%] men and 15 603 [55·4%] women) completed the survey between July 22, 2013, and March 5, 2015. Ethnicity data (Han or non-Han) were collected for only a subsample. Prevalence of any depressive disorders was higher in women than men (lifetime prevalence odds ratio [OR] 1·44 [95% CI 1·20-1·72] and 12-month prevalence OR 1·41 [1·12-1·78]), in unemployed people than employed people (lifetime OR 2·38 [95% CI 1·68-3·38] and 12-month OR 2·80 [95% CI 1·88-4·18]), and in people who were separated, widowed, or divorced compared with those who were married or cohabiting (lifetime OR 1·87 [95% CI 1·39-2·51] and 12-month OR 1·85 [95% CI 1·40-2·46]). Overall, 574 (weighted % 75·9%) of 744 people with 12-month depressive disorders had role impairment of any SDS domain: 439 (83·6%) of 534 respondents with major depressive disorder, 207 (79·8%) of 254 respondents with dysthymic disorder, and 122 (59·9%) of 189 respondents with depressive disorder not otherwise specified. Only an estimated 84 (weighted % 9·5%) of 1007 participants with 12-month depressive disorders were treated in any treatment sector: 38 (3·6%) in speciality mental health, 20 (1·5%) in general medical, two (0·3%) in human services, and 21 (2·7%) in complementary and alternative medicine. Only 12 (0·5%) of 1007 participants with depressive disorders were treated adequately. Interpretation: Depressive disorders in China were more prevalent in women than men, unemployed people than employed, and those who were separated, widowed, or divorced than people who were married or cohabiting. Most people with depressive disorders reported social impairment. Treatment rates were very low, and few people received adequate treatment. National programmes are needed to remove barriers to availability, accessibility, and acceptability of care for depression in China.

Socioeconomic disparities in first stroke incidence, quality of care, and survival: a nationwide registry-based cohort study of 44 million adults in England.

Background: We aimed to estimate socioeconomic disparities in the incidence of hospitalisation for first-ever stroke, quality of care, and post-stroke survival for the adult population of England. Methods: In this cohort study, we obtained data collected by a nationwide register on patients aged 18 years or older hospitalised for first-ever acute ischaemic stroke or primary intracerebral haemorrhage in England from July 1, 2013, to March 31, 2016. We classified socioeconomic status at the level of Lower Super Output Areas using the Index of Multiple Deprivation, a neighbourhood measure of deprivation. Multivariable models were fitted to estimate the incidence of hospitalisation for first stroke (negative binomial), quality of care using 12 quality metrics (multilevel logistic), and all-cause 1 year case fatality (Cox proportional hazards). Findings: Of the 43·8 million adults in England, 145 324 were admitted to hospital with their first-ever stroke: 126 640 (87%) with ischaemic stroke, 17 233 (12%) with intracerebral haemorrhage, and 1451 (1%) with undetermined stroke type. We observed a socioeconomic gradient in the incidence of hospitalisation for ischaemic stroke (adjusted incidence rate ratio 2·0, 95% CI 1·7-2·3 for the most vs least deprived deciles) and intracerebral haemorrhage (1·6, 1·3-1·9). Patients from the lowest socioeconomic groups had first stroke a median of 7 years earlier than those from the highest (p<0·0001), and had a higher prevalence of pre-stroke disability and diabetes. Patients from lower socioeconomic groups were less likely to receive five of 12 care processes but were more likely to receive early supported discharge (adjusted odds ratio 1·14, 95% CI 1·07-1·22). Low socioeconomic status was associated with a 26% higher adjusted risk of 1-year mortality (adjusted hazard ratio 1·26, 95% CI 1·20-1·33, for highest vs lowest deprivation decile), but this gradient was largely attenuated after adjustment for the presence of pre-stroke diabetes, hypertension, and atrial fibrillation (1·11, 1·05-1·17). Interpretation: Wide socioeconomic disparities exist in the burden of ischaemic stroke and intracerebral haemorrhage in England, most notably in stroke hospitalisation risk and case fatality and, to a lesser extent, in the quality of health care. Reducing these disparities requires interventions to improve the quality of acute stroke care and address disparities in cardiovascular risk factors present before stroke.

Prevalence Estimates of Amyloid Abnormality Across the Alzheimer Disease Clinical Spectrum.

Importance: One characteristic histopathological event in Alzheimer disease (AD) is cerebral amyloid aggregation, which can be detected by biomarkers in cerebrospinal fluid (CSF) and on positron emission tomography (PET) scans. Prevalence estimates of amyloid pathology are important for health care planning and clinical trial design. Objective: To estimate the prevalence of amyloid abnormality in persons with normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia and to examine the potential implications of cutoff methods, biomarker modality (CSF or PET), age, sex, APOE genotype, educational level, geographical region, and dementia severity for these estimates. Design, setting, and participants: This cross-sectional, individual-participant pooled study included participants from 85 Amyloid Biomarker Study cohorts. Data collection was performed from January 1, 2013, to December 31, 2020. Participants had normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia. Normal cognition and subjective cognitive decline were defined by normal scores on cognitive tests, with the presence of cognitive complaints defining subjective cognitive decline. Mild cognitive impairment and clinical AD dementia were diagnosed according to published criteria. Exposures: Alzheimer disease biomarkers detected on PET or in CSF. Main outcomes and measures: Amyloid measurements were dichotomized as normal or abnormal using cohort-provided cutoffs for CSF or PET or by visual reading for PET. Adjusted data-driven cutoffs for abnormal amyloid were calculated using gaussian mixture modeling. Prevalence of amyloid abnormality was estimated according to age, sex, cognitive status, biomarker modality, APOE carrier status, educational level, geographical location, and dementia severity using generalized estimating equations. Results: Among the 19 097 participants (mean [SD] age, 69.1 [9.8] years; 10 148 women [53.1%]) included, 10 139 (53.1%) underwent an amyloid PET scan and 8958 (46.9%) had an amyloid CSF measurement. Using cohort-provided cutoffs, amyloid abnormality prevalences were similar to 2015 estimates for individuals without dementia and were similar across PET- and CSF-based estimates (24%; 95% CI, 21%-28%) in participants with normal cognition, 27% (95% CI, 21%-33%) in participants with subjective cognitive decline, and 51% (95% CI, 46%-56%) in participants with mild cognitive impairment, whereas for clinical AD dementia the estimates were higher for PET than CSF (87% vs 79%; mean difference, 8%; 95% CI, 0%-16%; P = .04). Gaussian mixture modeling-based cutoffs for amyloid measures on PET scans were similar to cohort-provided cutoffs and were not adjusted. Adjusted CSF cutoffs resulted in a 10% higher amyloid abnormality prevalence than PET-based estimates in persons with normal cognition (mean difference, 9%; 95% CI, 3%-15%; P = .004), subjective cognitive decline (9%; 95% CI, 3%-15%; P = .005), and mild cognitive impairment (10%; 95% CI, 3%-17%; P = .004), whereas the estimates were comparable in persons with clinical AD dementia (mean difference, 4%; 95% CI, -2% to 9%; P = .18). Conclusions and relevance: This study found that CSF-based estimates using adjusted data-driven cutoffs were up to 10% higher than PET-based estimates in people without dementia, whereas the results were similar among people with dementia. This finding suggests that preclinical and prodromal AD may be more prevalent than previously estimated, which has important implications for clinical trial recruitment strategies and health care planning policies.

Predictors of treatment resistance in patients with schizophrenia: a population-based cohort study.

Background: Identification of patients at high risk of treatment-resistant schizophrenia at the time of schizophrenia diagnosis would be of great clinical benefit in minimising the delay to clozapine treatment in patients unlikely to respond to non-clozapine antipsychotics. However, little is known about predictors of treatment resistance in this patient population. We used a treatment-based proxy for treatment-resistant schizophrenia to identify candidate predictors of treatment resistance at first hospital contact with a schizophrenia diagnosis. Methods: In this population-based cohort study, we obtained Danish national registry data for all adult patients (≥18 years) with incident schizophrenia diagnosed between Jan 1, 1996, and Dec 31, 2006, and followed up until Dec 31, 2010. Our main proxy definition of treatment-resistant schizophrenia was the earliest instance of either clozapine initiation or hospital admission for schizophrenia after having had two periods of different antipsychotic monotherapy. We did multivariable Cox proportional hazards regression analysis to estimate the association between baseline candidate predictors and treatment resistance. Findings: 8624 patients fulfilled the criteria for inclusion. In multivariable complete-case analyses, 1703 (21%) of 8044 patients fulfilled the main proxy definition of treatment-resistant schizophrenia during a median follow-up of 9·1 years (IQR 6·3-11·9). Younger age (hazard ratio 0·96 [95% CI 0·95-0·97]), living in a less urban area (provincial 1·38 [1·23-1·56], rural 1·44 [1·25-1·65]), primary education level (0·88 [0·79-0·98]), more than 30 bed-days in psychiatric hospital in the year before first schizophrenia diagnosis (1·54 [1·35-1·75]), inpatient at first schizophrenia diagnosis (2·07 [1·87-2·29]), paranoid subtype (1·24 [1·13-1·37]), comorbid personality disorder (1·24 [1·11-1·39]), psychotropic drug use (antipsychotics 1·51 [1·35-1·69], antidepressants 1·15 [1·03-1·29], and benzodiazepines 1·22 [1·10-1·37]), and previous suicide attempt (1·21 [1·07-1·39]) were all significantly associated with treatment-resistant schizophrenia. Interpretation: Our study identifies several candidate predictors that could potentially be included in future prediction models for treatment-resistant schizophrenia. Notably, established risk factors for schizophrenia did not predict treatment resistance, suggesting that treatment-resistant disease might be a distinct subtype of schizophrenia and not merely a more severe form.

Mental health and its correlates among children and adolescents during COVID-19 school closure: The importance of parent-child discussion.

Background: School closures due to the COVID-19 outbreak have affected 87% of the world's students physically, socially, and psychologically, yet rigorous investigation into their mental health during this period is still lacking. Methods: A cross-sectional online survey of 4-342 primary and secondary school students from Shanghai, China was conducted during March 13-23, 2020. Besides demographic information, psychological distress (including depression, anxiety, and stress), life satisfaction, perceived impact of home quarantine, and parent-child discussions on COVID-19 were assessed. Results: The three most prevalent symptoms were: anxiety (24.9%), depression (19.7%), and stress (15.2%). Participants were generally satisfied with life and 21.4% became more satisfied with life during school closures. Senior grades were positively correlated with psychopathological symptoms and negatively associated with life satisfaction, whereas the perceived benefit from home quarantine and parent-child discussions on COVID-19 were negatively correlated with psychopathological symptoms and positively correlated with life satisfaction. Among participants who perceived no benefit from home quarantine, those who had discussions with their parents about COVID-19 experienced less depression, anxiety, and stress. Limitations: Limitations included the inability to infer the casual relationship, no parental report for mental health of children aged 6 to 9, and the inadequate measurement of parent-child discussion. Conclusions: Mental health problems and resilience co-existed in children and adolescents during the COVID-19 outbreak. Given the important role of parent-child discussions, open communication between parents and children about the pandemic should be encouraged to help children and adolescents cope with mental health problems in public health crisis.

A Validation of Six Wearable Devices for Estimating Sleep, Heart Rate and Heart Rate Variability in Healthy Adults.

The primary aim of this study was to examine the validity of six commonly used wearable devices, i.e., Apple Watch S6, Garmin Forerunner 245 Music, Polar Vantage V, Oura Ring Generation 2, WHOOP 3.0 and Somfit, for assessing sleep. The secondary aim was to examine the validity of the six devices for assessing heart rate and heart rate variability during, or just prior to, night-time sleep. Fifty-three adults (26 F, 27 M, aged 25.4 ± 5.9 years) spent a single night in a sleep laboratory with 9 h in bed (23:00-08:00 h). Participants were fitted with all six wearable devices-and with polysomnography and electrocardiography for gold-standard assessment of sleep and heart rate, respectively. Compared with polysomnography, agreement (and Cohen's kappa) for two-state categorisation of sleep periods (as sleep or wake) was 88% (κ = 0.30) for Apple Watch; 89% (κ = 0.35) for Garmin; 87% (κ = 0.44) for Polar; 89% (κ = 0.51) for Oura; 86% (κ = 0.44) for WHOOP and 87% (κ = 0.48) for Somfit. Compared with polysomnography, agreement (and Cohen's kappa) for multi-state categorisation of sleep periods (as a specific sleep stage or wake) was 53% (κ = 0.20) for Apple Watch; 50% (κ = 0.25) for Garmin; 51% (κ = 0.28) for Polar; 61% (κ = 0.43) for Oura; 60% (κ = 0.44) for WHOOP and 65% (κ = 0.52) for Somfit. Analyses regarding the two-state categorisation of sleep indicate that all six devices are valid for the field-based assessment of the timing and duration of sleep. However, analyses regarding the multi-state categorisation of sleep indicate that all six devices require improvement for the assessment of specific sleep stages. As the use of wearable devices that are valid for the assessment of sleep increases in the general community, so too does the potential to answer research questions that were previously impractical or impossible to address-in some way, we could consider that the whole world is becoming a sleep laboratory.

A Multidimensional Tool Based on the eHealth Literacy Framework: Development and Initial Validity Testing of the eHealth Literacy Questionnaire (eHLQ).

Background: For people to be able to access, understand, and benefit from the increasing digitalization of health services, it is critical that services are provided in a way that meets the user's needs, resources, and competence. Objective: The objective of the study was to develop a questionnaire that captures the 7-dimensional eHealth Literacy Framework (eHLF). Methods: Draft items were created in parallel in English and Danish. The items were generated from 450 statements collected during the conceptual development of eHLF. In all, 57 items (7 to 9 items per scale) were generated and adjusted after cognitive testing. Items were tested in 475 people recruited from settings in which the scale was intended to be used (community and health care settings) and including people with a range of chronic conditions. Measurement properties were assessed using approaches from item response theory (IRT) and classical test theory (CTT) such as confirmatory factor analysis (CFA) and reliability using composite scale reliability (CSR); potential bias due to age and sex was evaluated using differential item functioning (DIF). Results: CFA confirmed the presence of the 7 a priori dimensions of eHLF. Following item analysis, a 35-item 7-scale questionnaire was constructed, covering (1) using technology to process health information (5 items, CSR=.84), (2) understanding of health concepts and language (5 items, CSR=.75), (3) ability to actively engage with digital services (5 items, CSR=.86), (4) feel safe and in control (5 items, CSR=.87), (5) motivated to engage with digital services (5 items, CSR=.84), (6) access to digital services that work (6 items, CSR=.77), and (7) digital services that suit individual needs (4 items, CSR=.85). A 7-factor CFA model, using small-variance priors for cross-loadings and residual correlations, had a satisfactory fit (posterior productive P value: .27, 95% CI for the difference between the observed and replicated chi-square values: -63.7 to 133.8). The CFA showed that all items loaded strongly on their respective factors. The IRT analysis showed that no items were found to have disordered thresholds. For most scales, discriminant validity was acceptable; however, 2 pairs of dimensions were highly correlated; dimensions 1 and 5 (r=.95), and dimensions 6 and 7 (r=.96). All dimensions were retained because of strong content differentiation and potential causal relationships between these dimensions. There is no evidence of DIF. Conclusions: The eHealth Literacy Questionnaire (eHLQ) is a multidimensional tool based on a well-defined a priori eHLF framework with robust properties. It has satisfactory evidence of construct validity and reliable measurement across a broad range of concepts (using both CTT and IRT traditions) in various groups. It is designed to be used to understand and evaluate people's interaction with digital health services.

A multimedia mobile phone-based youth smoking cessation intervention: findings from content development and piloting studies.

Background: While most young people who smoke want to quit, few access cessation support services. Mobile phone-based cessation programs are ideal for young people: mobile phones are the most common means of peer communication, and messages can be delivered in an anonymous manner, anywhere, anytime. Following the success of our text messaging smoking cessation program, we developed an innovative multimedia mobile phone smoking cessation intervention. Objective: The aim of the study was to develop and pilot test a youth-oriented multimedia smoking cessation intervention delivered solely by mobile phone. Methods: Development included creating content and building the technology platform. Content development was overseen by an expert group who advised on youth development principles, observational learning (from social cognitive theory), effective smoking cessation interventions, and social marketing. Young people participated in three content development phases (consultation via focus groups and an online survey, content pre-testing, and selection of role models). Video and text messages were then developed, incorporating the findings from this research. Information technology systems were established to support the delivery of the multimedia messages by mobile phone. A pilot study using an abbreviated 4-week program of video and text content tested the reliability of the systems and the acceptability of the intervention. Results: Approximately 180 young people participated in the consultation phase. There was a high priority placed on music for relaxation (75%) and an interest in interacting with others in the program (40% would read messages, 36% would read a blog). Findings from the pre-testing phase (n = 41) included the importance of selecting "real" and "honest" role models with believable stories, and an interest in animations (37%). Of the 15 participants who took part in the pilot study, 13 (87%) were available for follow-up interviews at 4 weeks: 12 participants liked the program or liked it most of the time and found the role model to be believable; 7 liked the role model video messages (5 were unsure); 8 used the extra assistance for cravings; and 9 were happy with two messages per day. Nine participants (60%) stopped smoking during the program. Some technical challenges were encountered during the pilot study. Conclusions: A multimedia mobile phone smoking cessation program is technically feasible, and the content developed is appropriate for this medium and is acceptable to our target population. These results have informed the design of a 6-month intervention currently being evaluated for its effectiveness in increasing smoking cessation rates in young people.

Problematic Internet use: an overview

The “global village”, a metaphor used to describe how the Internet has shortened distances and facilitated the flow of information, has grown to over one billion users 1. Statistics from across the world highlight its reach and penetrance: 90% of South Korean households connect to high-speed, inexpensive broadband 2; Londoners spend an average of 45 days a year online, more than they spend watching TV 3; and the rate of increase in the number of Internet users in Africa and the Middle East exceeded 1,300% between 2000 and 2009 4. For the majority of Internet users, the World Wide Web represents a tremendous wellspring of opportunity that enhances well-being. For others, however, it can lead to a state that appears to meet the DSM definition of a mental disorder, described as a “clinically significant behavioral or psychological syndrome…that is associated with present distress… or with a significantly increased risk of suffering death, pain, disability, or an important loss of freedom” 5. Scientific understanding of that state has lagged behind media attention 6, in part because of inconsistency in defining the problem 7, disagreement about its very existence 8, and the variable research methodology used in studying it. Still, a body of data by scientists from the East and West (with the East increasingly leading the way) tells a cautionary tale about the Internet's potential to bring about psychological harm. In 1996, the psychologist K. Young became the first to publish a detailed case report of problematic Internet use 9. Her “patient zero” was a non-technologically oriented 43-year-old homemaker with a “content home life and no prior addiction or psychiatric history”, who, within three months of discovering chat rooms, was spending up to 60 hours per week online. She reported feeling excited in front of the computer, and depressed, anxious, and irritable when she would log off. She described having an addiction to the medium “like one would to alcohol”. Within one year of purchasing her home computer, she was ignoring household chores, had quit social activities she used to enjoy, and had become estranged from her two teenage daughters and her husband of 17 years. Based on this and other patients she interviewed, Young proposed the first set of diagnostic criteria for what she termed “Internet addiction”. She modeled them on the DSM-IV definition for substance dependence because of similarities she observed with the states of tolerance (needing more of the substance to achieve the same effect) and withdrawal (psychological and physical discomfort upon reducing or stopping the substance) 9. Others conceptualized problematic Internet use as a behavioral addiction not involving an intoxicant 10, and Young subsequently updated her definition, adapting the DSM-IV criteria for pathological gambling, an impulse control disorder often described as a behavioral addiction, into her Diagnostic Questionnaire 11 (Table 1). The questionnaire, which required at least five of the eight criteria be met for the Internet addiction diagnosis, has not received adequate psychometric testing. Shapira et al 12 proposed five years later a more inclusive diagnostic schema in the general style of the impulse control disorders. They argued that definitions based solely on substance dependence or pathological gambling were too narrow to capture the population of problematic Internet users and could lead to premature conclusions about the new disorder and the patients. They eschewed the “Internet addiction” label for lack of scientific proof for true addiction and favored the less controversial “problematic Internet use”, defining it as: a) maladaptive preoccupation with Internet use, experienced as irresistible use for periods of time longer than intended; b) significant distress or impairment resulting from the behavior; and c) the absence of other Axis I pathology that might explain the behavior, such as mania or hypomania. To date, only two studies have attempted to develop diagnostic criteria empirically by testing them against the diagnosis made on the basis of a systematic psychiatric interview. Ko et al 13 tested a set of criteria in 468 Taiwanese high school students. Starting with 13 candidate criteria, they eliminated those with low diagnostic accuracy, and determined that a cutoff of six out of the nine remaining criteria had the best diagnostic accuracy while maintaining high specificity (97.1%) and acceptable sensitivity (87.5%). The criterion for functional impairment was listed separately as criterion B and was required for the diagnosis (Table 2). In a second study, Ko et al 14 confirmed the diagnostic accuracy of their criteria in an older cohort of 216 Taiwanese college students. However, the relatively small size of both studies and the non-representative nature of the groups studied limit the applicability of the proposed criteria to the general population. Several assessment scales have been proposed to screen for, and help diagnose, problematic Internet use. As a group, these instruments show no consensus on the underlying dimensions that constitute the condition 6,15. In addition to Young's Diagnostic Questionnaire, two are in relatively common use in research and/or clinical settings: Young's Internet Addiction Test 16 and the Chen Internet Addiction Scale 17. Young's Internet Addiction Test 16 consists of 20 “how-often” questions, each rated on a scale of 1 to 5 (1=rarely; 2=occasionally; 3=frequently; 4=often; 5=always.) A score of 80 or above is consistent with problematic use (Table 3). The psychometric properties of the instrument were studied in 86 subjects 18. Six factors were extracted from the questionnaire: salience, excessive use, neglect of work, anticipation, lack of control, and neglect of social life. These factors showed good concurrent validity and internal consistency. Salience explained most of the variance and was also found to be the most reliable as indicated by its Cronbach's alpha. However, the selection bias introduced by online recruitment and the small size of the study limit its value. The Chen Internet Addiction Scale 17 is a self-report instrument composed of 26 items rated on a 4-point Likert scale (adapted in Table 4). It assesses five domains of Internet-related problems: compulsive use, withdrawal, tolerance, interpersonal and health consequences, and time management difficulties. Scores range from 26 to 104. In a study of 454 Taiwanese adolescents who completed the scale and received a structured diagnostic interview, a cutoff of 64 was shown to have high diagnostic accuracy and specificity (88% and 92.6%, respectively) 19. The internal reliability of the scale and subscales in the original study ranged from 0.79 to 0.93 17. Due to the lack of consensus on diagnostic criteria and the dearth of large epidemiological studies, the prevalence of problematic Internet use in the general population has not been established. Overall, prevalence surveys conducted in various countries fall into two main categories, online vs. offline studies, with the former typically yielding higher rates, most likely because of inherent selection bias 20. Only two epidemiological studies exploring the prevalence of problematic Internet use in the general population have been published. One was conducted in the US, the other in Norway 20,21. The US study used random-digit telephone dialing (cellular phone numbers were not included) to interview 2,513 adults taken from all 50 states in a manner proportional to the population in each state 20. More than half of the people reached agreed to be interviewed. Participants’ average age was 48, and 51% fell in the middle class socioeconomic stratum. 68.9% were regular Internet users. The authors’ diagnostic definition, based on published criteria and on similarities with impulse control disorders, substance dependence and obsessive-compulsive disorder, required: a) Internet use that interferes in personal relationships; b) preoccupation with the Internet when offline; c) unsuccessful attempts at quitting or cutting down; and d) staying online longer than intended. This definition yielded a point prevalence of 0.7%. Less stringent definitions yielded higher prevalence rates, and individual features consistent with problematic Internet use were endorsed by as many as 13.7% (respondents who found it hard to stay offline for days in a row). In the second study, Bakken et al 21 mailed Young's Diagnostic Questionnaire to 10,000 inhabitants of Norway, randomly selected from a database of the entire population. 3,399 completed questionnaires were returned (a somewhat lower response rate than the US study). Recipients of the mailed questionnaire also had the option of completing it online. Among respondents, 87% were Internet users. The prevalence of “addicted Internet use” (≥5 questions answered “yes”) was calculated to be 1%, whereas the prevalence of “at risk” Internet use (3–4 questions answered “yes”) was 5.2%. Multivariate analysis showed young age, male gender, higher educational achievement, and financial stress to be positively associated with “problematic Internet use” (defined by the authors to include both “Internet addicts” and “at risk” respondents). Prevalence rates among adolescents have been researched more extensively, perhaps because the so-called “digital natives” grew up incorporating the Internet in many aspects of life and as a result are perceived to be at higher risk. However, even when online-based surveys are excluded, the results can vary widely and are difficult to compare, due to differences in Internet access, recruitment methodology, the exact age bracket studied, and the definitions utilized. Considering only relatively large and offline studies, research from China 22, South Korea 23,24, Greece 25, Norway 26, and Iran 27 has yielded prevalence estimates ranging between 2% and 11%. Problematic Internet use has not been incorporated into large-scale epidemiological studies aimed at estimating the relative prevalence of mental disorders. Still, a review of published studies reveals that the presence of other psychiatric conditions in patients with problematic Internet use is the rule rather than the exception 6. The studies, however, were not designed or statistically powered to detect the nature of the association (cause, effect, or independent). In Bakken's general-population study 21, based on subjects’ self-report, 41.4% of Internet “addicts” reported feelings of depression in the 12-month period prior to the study, compared to 15.8% of non-problematic users. Sleep disturbances, anxious feelings, and alcohol and substance abuse were also more common (38.6% vs. 26.4%, 36.4% vs. 5%, and 13.6% vs. 1.1%, respectively). However, the questions used to assess co-occurring psychological impairment were not based on established criteria for mood, sleep, anxiety, or substance use disorders. Two US case series involved face-to-face interviews of adult patients with problematic Internet use. Black et al 28 assessed 21 subjects with the Diagnostic Interview Schedule and found the lifetime prevalence of mood disorders and major depression to be 33% and 15%, respectively. Further, 38% had a lifetime substance use disorder and 19% had a lifetime diagnosis of anxiety disorder. In a case series that included 20 patients, Shapira et al 29 found a very high (70%) lifetime prevalence for bipolar affective disorder, type I or II, compared with 15% for major depression. Fifty-five percent had a lifetime prevalence of substance abuse, and 45% met criteria for social anxiety disorder. Fifty percent of subjects had a lifetime diagnosis of an impulse control disorder. The authors highlight their observation that patients’ Internet-related symptoms were more impulsive and egosyntonic than compulsive and egodystonic, concluding that problematic Internet use resembles the DSM-IV definition of an impulse control disorder more closely than that of obsessive-compulsive disorder. Our clinical experience supports this conclusion. As a group, surveys conducted among high school and college students show similarly high comorbidity rates with mood and anxiety disorders, but a link between attention-deficit/hyperactivity disorder (ADHD) and problematic Internet use seems more obvious than among adults. One study in 752 South Korean elementary students found that 33% of those with ADHD also met criteria for problematic Internet use 30. Another study in 216 Taiwanese college students showed that 32% subjects with problematic Internet use also had ADHD compared to only 8% of regular Internet users 31. Whether Web-based activities appeal to the short attention span of ADHD sufferers or whether excessive Internet use may cause inattention remains to be elucidated. The clinical evaluation of the patient with problematic Internet use should include a careful assessment of the comorbid conditions frequently present. Those should then be treated according to established treatment guidelines. To the extent that the Internet-related problem may stem from another diagnosis (e.g., a patient with severe social anxiety who starts leading a “virtual” life at the expense of offline interactions), it might improve as the primary condition is addressed. Pharmacotherapeutic and psychotherapeutic interventions specific to problematic Internet use have not yet received adequate testing in large, rigorous studies. Pharmacotherapy often begins with selective serotonin reuptake inhibitors (SSRIs). However, while effective in treating obsessive-compulsive disorder, SSRIs have shown mixed results in impulse control disorders 32,33,34,35–36. In light of the greater similarity between problematic Internet use and impulse control disorders compared to obsessive-compulsive disorder 29, it is unclear whether SSRIs will ultimately prove beneficial, and no double-blind placebo-controlled studies have been published so far. One discontinuation study tested escitalopram, 20 mg/day, in 19 subjects with problematic Internet use 37. During the 10-week open-label phase, subjects showed significant decreases in weekly hours spent online (from a mean of 36.8 hours to 16.5 hours) and improvement in global functioning. At the end of the 10 weeks, subjects were blindly randomized to either continued escitalopram treatment or to placebo. Beyond that, they were followed for 9 weeks. No significant difference was seen between the two groups at the end of the second phase, as gains achieved at week 10 were maintained in both treatment groups. The authors speculate that nine weeks may have not been sufficient for the effect to be lost in the placebo group or for additional gains to be made in the escitalopram group, but do not rule out the possibility that the improvement seen in the open-label phase may have been a placebo response. One case study reported successful treatment with naltrexone 38, a drug that has shown benefit in other impulse control disorders 39,40. The patient was a 31 year old male with compulsive cybersexual behavior who had failed antidepressants, group and individual psychotherapy, Sexual Addicts Anonymous, and pastoral counseling. Naltrexone (150 mg/day), gradually added to a stable dose of sertraline which on its own had been ineffective in treating his problematic Internet use, helped induce a three-year remission. The authors hypothesize that, by blocking the capacity of endogenous opioids to trigger dopamine release in response to reward, naltrexone may block the reinforcing nature of compulsive Internet sexual activity. Another case study reported the successful use of an atypical antipsychotic, quetiapine, 200 mg/day, gradually added to citalopram, in a 23 year old subject with problematic Internet use 41. The improvement was maintained at four-month follow-up. More recently, a study tested methylphenidate in 62 children with ADHD who were Internet video game players 42. Participants’ average age was around 9. After 8 weeks of treatment (average dose 30.5 mg/day), Internet usage decreased significantly and correlated with reduction in ADHD symptoms. The authors cautiously suggest that methylphenidate might be beneficial as a treatment for problematic Internet use, especially when co-occurring with ADHD. Of the psychotherapy approaches used, cognitive behavioral therapy (CBT) has received the most empiric investigation. The largest study enrolled 114 adult subjects and employed CBT interventions including: keeping a daily log of Internet activity, teaching time management skills, and confronting cognitive distortions and rationalizations frequently used by patients to justify continued Internet usage, such as “just a few more minutes won't hurt” 43. Most subjects were able to control their symptoms by the eighth session, and improvement was sustained over a 6-month follow-up. For children and adolescents, family-based interventions that improve communication and teach family monitoring of Internet use can be helpful 44. However, the intensive (and typically very expensive) residential treatment options that have received much media attention have undergone little empiric investigation to warrant a strong recommendation 2,45. The same applies to online treatment websites that encourage the person with problematic Internet use to “click here if you are addicted to the Internet”. For a medium that has so radically changed the way we conduct our lives, the Internet's effects on our psychological health remain understudied. Simply stating that similar fears were raised when the radio, movies and early video games were introduced is not sufficient: the immersive and interactive qualities of the virtual world, and its sheer penetrance, make it potentially more serious. Also deserving of exploration are the more subtle psychological changes that occur in the virtual world, such as online disinhibition and increased risk-taking 46. Those changes are not necessarily evidence of “Internet addiction”, and may not be pathological, but, as important features of the new virtual psychology, should also be studied. As our field continues to debate whether their condition belongs in the next edition of the DSM 47, patients continue to present with symptoms born out of the digital age, and their symptoms are changing as the technology evolves from browsers, to “crackberries”, to “smart phones” that combine texting, talking, video games, and browsing in one device that to many is like a new appendage. Even the “problematic Internet use” designation now seems outdated, which is why some have wisely opted for “pathological use of electronic media”, instead 47. Technology, like media outlets, remains far ahead of scientific investigation. Given the dramatic changes that our society is undergoing as a result of the Internet revolution, it behooves us to try to bridge the gap.

Life Review in Critical Care: Possibilities at the End of Life

The therapeutic use of life review provides nurses with a framework for clinical interactions. It was a short but memorable clinical encounter, initiated with the eldest of 3 living sons. The men’s mother, an 87-year-old frail, Chinese-born woman, had just been terminally extubated. A palliative care nurse was facilitating the woman’s life review with the sons, who were recounting harrowing tales of their mother’s life in Hong Kong during World War II: how people commonly ate animals off the street and weeds growing in the cracks of buildings to survive. Prompted to share their “gifts of the heart”—what their mother taught them about life and living that would resonate in their hearts—the sons spent the next hour in soft-spoken reflection at the bedside. As time progressed, a healing space was created, echoing the words of Curtis and Eldridge2(pp38–40):Using the palliative care consultation service of Lakeland Regional Medical Center, Lakeland, Florida, as a model, we offer clinical nurses an opportunity to extend practice beyond the physical care of patients at the end of life. When a patient’s goals of care clearly shift from cure to comfort, life review provides an evidence-based approach for interaction with the patient’s family. Using the theory and techniques we describe, practitioners can alleviate suffering, for the concern of nursing is “broader than the organ system that is affected, as we turn our attention to the emotional, physical and spiritual health of the whole patient.”3(p17)In her book Kitchen Table Wisdom: Stories That Heal, 4(ppxxvi–xxvii) Remen speaks of being deeply moved by her patients’ stories, “by the people and the meaning they found in their problems, by the unsuspected strengths, the depths of love and devotion. . . . Everybody is a story. . . . Everyone’s story matters.”Referring to a progressive return of the memories of past experience in search of meaning and in striving for emotional resolution, life review is a formal concept that has its roots in life-span developmental psychology.5 As defined by the theories of Butler5 and Erikson,6 development is shaped by countless factors throughout the entire life span: the historical time in which one lives, the economics and culture, and the positive and negative life circumstances.5–9 In his 1963 article,5(p66) Butler theorized that life review was aLife review has applications in varied situations, such as cultural transmission, anthropological field work, and career planning and vocational guidance.8 However, its therapeutic use provides nurses a framework for clinical interactions. Life review has been described as a recasting of the past in the context of the present10: the chance to reexamine one’s life and solve old problems, the chance to make amends and restore harmony,11 and the chance to “find new meaning in the face of impending death.”12(p120) Widely practiced in gerontology,6,11,12 life review is thought to be a useful method for understanding both self and others.13 In gerontology, multiple and consecutive weekly sessions are used to analyze, evaluate, and synthesize life events.14,15 Investigators16,17 have addressed adaptations of life review with terminally ill patients, situations in which time with patients and patients’ families was often limited because of the severity of the illness. Additionally, we (M.J., P.A.) have had countless single clinical encounters in which the therapeutic use of life review has been used, supporting the counsel of Byock18 to “create a space where healing can happen” and to “use a few moments to go deep—even when time is really short.”When any form of life review is undertaken, a life is examined, and questions such as the following19 are asked: Who am I? How did I do? How did I live my life? Thus, an important difference between reminiscence and review must be addressed. Life review is “not a random sharing of pleasurable past events, but rather a structured process containing a component of self-evaluation.”14(p9) Life review can be used with both patients and patients’ families; the outcomes include increased life satisfaction and accomplishment, promotion of peaceful feelings, and a state of integrity.20 Furthermore, Garland and Garland8 contend that life review has a distinct purpose in end-of-life care by upholding the unique value of each person’s life. These themes are consistent with Erikson’s theories of development6: the final task is ego integrity versus ego despair. Ego integrity6 involves acceptance of the course of one’s life, acceptance of one’s place in history, absence of death-anxiety, and satisfaction with life. In contrast, ego despair echoes in the words of the poet Robert Frost21: “. . . nothing to look backward to with pride, and nothing to look forward to with hope, so now and never any different.”Each health care provider can be inspired by the Institute of Medicine report Approaching Death: Improving Care at the End of Life22:Byock23(p36) builds on this vision, contending that a solely physiological approach with the terminally ill is “two-dimensional, and without the color, tone, or texture of life.” Additionally, Volker and Limerick24 explored the concept of dignified dying. In their interviews with advanced practice nurses in oncology, the theme of “going in peace” emerged, which referred to “the importance of connecting with loved ones; conveying final messages; dying in a quiet, nonchaotic environment; not suffering from physical or existential distress; and meeting spiritual needs.”24(p244)Irrespective of the clinical setting, the grief that is expressed at any bedside represents a “developmental crisis that becomes interwoven with family history.”25(p17) Although Butler’s concept of life review5 traditionally involves a patient and a health care practitioner, life review in critical care usually involves a patient’s family members, who become survivors if the patient dies. Compared with those who do not engage in life review, survivors who purposefully recount the events of their loved one’s life and death maintain a higher level of emotional function, such as moving appropriately through the grieving process and retaining the ability to perform activities of daily living. In support of this approach, many authors8,26–28 have articulated that the physical effects of internal stress are reduced by the outward expression of emotion. According to Pennebaker,27 the continuous inhibition of traumatic memory is a physical stressor that adversely affects the immune system. The death of a loved one is clearly a major life stressor. Despite that loss, survivors who participate in life review have the following desired outcome: they retain or regain hope for the future and a passion for life. The 3 interconnected components of life review are recontextualizing, forgiving, and reclaiming unlived life.29Recontextualizing is using an expanded vision of maturity, referring to the wisdom that comes with age and experience. Recontextualizing is used to reframe self-defined mistakes and failures. First, past negative life events and situations must be reexamined or reframed in such a way that they can be perceived as positive. A person must be willing to view the past differently, even when reliving unpleasant or painful experiences. In contrast to viewing oneself as the “victim” of past negative events and experiences, recontextualizing offers the realization that one is often in control of life experiences and has the opportunity to change memories based on perception of the experiences. Recontextualizing allows a reflection on the past, thus repairing relationships and events. Changing the perception changes the memory, from one of failure to one of success.5,8,10,29 Recontextualizing involves the “search for the deeper, sometimes more elusive, patterns that may be operating beneath the surface of everyday events.”29(p117)Present during the life review of a man who was dying were the man’s wife of 59 years, 2 adult daughters, and 1 granddaughter. Between numerous tears, the younger daughter reluctantly and slowly spoke of childhood memories: when her father was always adamant that she fulfill her academic duties. Deeply resentful as a child and adolescent, she was able to trace her current value of responsibility, as well as her national stature in her field, to her father’s expectations when she was a child. Without this purposeful revisiting of past events, the daughter’s memory might have focused on that resentment. Remen26(p29) remarks:Offering forgiveness to another and oneself often has an important result for patients facing the end of life. Anger and resentment, previously concentrated in a negative effort, can now be redirected toward positive thoughts and attitudes.29 Byock30 recounts numerous clinical cases involving forgiveness and cautions about a frequent misconception. Forgiveness is not about absolving someone else’s responsibility. Yet, when a relationship is completed, the story of the fractured relationship is totally reframed: everything that happened before is a prologue to the healing.18 The repair of life review never eliminates the pain, but forgiveness work helps in coming to terms with the painful feelings.29These thoughts are duplicated by Archbishop Desmond Tutu, who won the Nobel Peace Prize in 1984 for his healing work in South Africa after apartheid. Tutu asserts as follows31(pp270–271,279):The following highlights the concept of forgiveness. A 72-year-old man was unresponsive and had been intubated after an extensive myocardial infarction and unknown down-time before resuscitation. His family assembled to spend time with him, but this gathering was no simple feat; the family did not regard their father as a model parent. As a result, the 5 middle-aged adult children were living separate and rather chaotic lives. Some lived in other states, those who lived in the local area rarely talked, and none knew the whereabouts of their mother. Because of the exceptional and harsh nature of the stories (marked by family chaos and alcohol abuse by both parents), it was critical for the facilitators who were listening to maintain a nonjudgmental and therapeutic stance, to build trust and rapport. When talking about their childhood experiences, the adult siblings began to relate the stories that they had heard, as well as those they had experienced. Life review became an opportunity to place their own stories beside the stories of their father’s life. Painful moments, which could not be denied, could at least be placed in the context of the patient’s troubled life. The entire family was willing to reflect on and laugh about the joys that had been a part of their life together, especially holiday memories. More importantly, they found parts of their lives that they could treasure beyond the earlier pain and the current grief. When life support was discontinued, the many years of separation softened as the siblings began to find a sense of forgiveness for their father and each other. The family discovered that their shared stories were allowing them to reconnect, for they had lived through challenging childhoods. Because of the chaotic nature of this family’s life, the reconnection might not be sustainable, but for one moment, the grieving siblings found a sense of grace, appreciation, and gratitude in their shared life review. Reclaiming an unlived life involves reflecting on an opportunity earlier in life that was never used.29 Regret is a common theme in such reflections and is a topic of growing interest to cognitive researchers. Common life regrets involve education (how misgivings about attending school affected other life decisions), career (lack of success or choice of career), romance (long-lost loves and unsuccessful relationships), family (doubts over parenting or estrangements from parents/siblings), and the self (disappointments in abilities, attitudes, and behaviors).32 In expanding on the classic poem of Robert Frost, Beazley33(p9) addresses the concept of The Road Not Taken asSuch reflection transpired during the extensive life review of a dying patient by his adult daughter. Years ago, an irreparable breach had been created between the patient and his sister; the 2 of them took the specific details of the rift to their graves. However, the patient’s daughter had the courage to examine the lost opportunity of a life with her cousins. Deciding to end the division, she contacted her cousins and invited them to join her at her father’s deathbed. One local cousin responded to her invitation. Among many tears and hugs, the cousins pledged to reunite the family, thus reclaiming a lost heritage. Schachter-Shalomi and Miller29(p93) relate the 3 components of life review to the concept of time:Not every critical situation is a terminal one. Yet, life review is an important tool in placing the trauma of critical illness and associated aggressive medical treatment into the broader context of one’s entire life.
