Quality of Life and Burnout Rates Across Surgical Specialties: A Systematic Review.
Importance: Establishing strategies to minimize the burden of burnout and poor quality of life (QOL) on surgeons relies on a thorough understanding of QOL and burnout among the various surgical specialties.
Objectives: To systematically review the literature across multiple surgical specialties and provide a comprehensive understanding of QOL and burnout among all surgeons, to delineate variation in rates of burnout and poor QOL, and to elucidate factors that are commonly implicated in these outcomes.
Evidence review: An OVID electronic search encompassing MEDLINE, PsycInfo, and EMBASE was completed using the following MeSH search terms: quality of life, burnout, surgeon, surgical specialty, and United States. Full articles published in English from January 1, 1980, to June 10, 2015, that evaluated US surgical specialists and included more than 1 question related to QOL were included. Review articles and evaluations that included medical students or nonsurgical health care professionals were excluded. Of 1420 titles, 41 articles met these criteria. The standardized methodologic principles of PRISMA for reporting systematic reviews guided analysis. Primary end points were QOL scores and burnout rates that compared sex, age, level of training (resident vs attending), surgical specialty, and the type of assessment tool. Secondary outcomes included proposed work hours and income as factors contributing to burnout. Owing to the heterogeneity of data reporting among articles, qualitative analysis was also reported.
Findings: Of the 16 specialties included, pediatric (86% to 96%) and endocrine (96%) surgeons demonstrated the highest career satisfaction, whereas a portion of plastic surgeons (33%) and vascular surgeons (64%) were least satisfied. The effect of sex was variable. Residents demonstrated a significantly higher risk for burnout than attending surgeons across multiple specialties, including obstetrics and gynecology, otolaryngology, and orthopedic surgery. One-third of the studies found hours worked per week to be a statistically significant predictor of burnout, decreased career satisfaction, and poorer QOL.
Conclusions and relevance: Burnout and QOL vary across all surgical specialties. Whether sex affects burnout rates remains unclear. Residents are at an increased risk for burnout and more likely to report a poor QOL than attending surgeons.

Psychotherapy for depression in older veterans via telemedicine: a randomised, open-label, non-inferiority trial.
Background: Many older adults with major depression, particularly veterans, do not have access to evidence-based psychotherapy. Telemedicine could increase access to best-practice care for older adults facing barriers of mobility, stigma, and geographical isolation. We aimed to establish non-inferiority of behavioural activation therapy for major depression delivered via telemedicine to same-room care in largely male, older adult veterans.
Methods: In this randomised, controlled, open-label, non-inferiority trial, we recruited veterans (aged ≥58 years) meeting DSM-IV criteria for major depressive disorder from the Ralph H Johnson Veterans Affairs Medical Center and four associated community outpatient-based clinics in the USA. We excluded actively psychotic or demented people, those with both suicidal ideation and clear intent, and those with substance dependence. The study coordinator randomly assigned participants (1:1; block size 2-6; stratified by race; computer-generated randomisation sequence by RGK) to eight sessions of behavioural activation for depression either via telemedicine or in the same room. The primary outcome was treatment response according to the Geriatric Depression Scale (GDS) and Beck Depression Inventory (BDI; defined as a 50% reduction in symptoms from baseline at 12 months), and Structured Clinical Interview for DSM-IV, clinician version (defined as no longer being diagnosed with major depressive disorder at 12 months follow-up), in the per-protocol population (those who completed at least four treatment sessions and for whom all outcome measurements were done). Those assessing outcomes were masked. The non-inferiority margin was 15%. This trial is registered with ClinicalTrials.gov, number NCT00324701.
Findings: Between April 1, 2007, and July 31, 2011, we screened 780 patients, and the study coordinator randomly assigned participants to either telemedicine (120 [50%]) or same-room treatment (121 [50%]). We included 100 (83%) patients in the per-protocol analysis in the telemedicine group and 104 (86%) in the same-room group. Treatment response according to GDS did not differ significantly between the telemedicine (22 [22·45%, 90% CI 15·52-29·38] patients) and same-room (21 [20·39%, 90% CI 13·86-26·92]) groups, with an absolute difference of 2·06% (90% CI -7·46 to 11·58). Response according to BDI also did not differ significantly (telemedicine 19 [24·05%, 90% CI 16·14-31·96] patients; same room 19 [23·17%, 90% CI 15·51-30·83]), with an absolute difference of 0·88% (90% CI -10·13 to 11·89). Response on the Structured Clinical Interview for DSM-IV, clinician version, also did not differ significantly (39 [43·33%, 90% CI 34·74-51·93] patients in the telemedicine group and 46 [48·42%, 90% CI 39·99-56·85] in the same-room group), with a difference of -5·09% (-17·13 to 6·95; p=0·487). Results from the intention-to-treat population were similar. MEM analyses showed that no significant differences existed between treatment trajectories over time for BDI and GDS. The criteria for non-inferiority were met. We did not note any adverse events.
Interpretation: Telemedicine-delivered psychotherapy for older adults with major depression is not inferior to same-room treatment. This finding shows that evidence-based psychotherapy can be delivered, without modification, via home-based telemedicine, and that this method can be used to overcome barriers to care associated with distance from and difficulty with attendance at in-person sessions in older adults.

(2015)MEDLINE-indexed journal, not yet read by usThe lancet. Diabetes & endocrinology · randomised controlled trial Effect of a behavioural intervention in obese pregnant women (the UPBEAT study): a multicentre, randomised controlled trial.
Background: Behavioural interventions might improve clinical outcomes in pregnant women who are obese. We aimed to investigate whether a complex intervention addressing diet and physical activity could reduce the incidence of gestational diabetes and large-for-gestational-age infants.
Methods: The UK Pregnancies Better Eating and Activity Trial (UPBEAT) is a randomised controlled trial done at antenatal clinics in eight hospitals in multi-ethnic, inner-city locations in the UK. We recruited pregnant women (15-18 weeks plus 6 days of gestation) older than 16 years who were obese (BMI ≥30 kg/m(2)). We randomly assigned participants to either a behavioural intervention or standard antenatal care with an internet-based, computer-generated, randomisation procedure, minimising by age, ethnic origin, centre, BMI, and parity. The intervention was delivered once a week through eight health trainer-led sessions. Primary outcomes were gestational diabetes (diagnosed with an oral glucose tolerance test and by criteria from the International Association of Diabetes in Pregnancy Study Groups) and large-for-gestational-age infants (≥90th customised birthweight centile). Analysis was by intention to treat. This trial is registered with Current Controlled Trials, ISCRTN89971375. Recruitment and pregnancy outcomes are complete but childhood follow-up is ongoing.
Findings: Between March 31, 2009, and June 2, 2014, we assessed 8820 women for eligibility and recruited 1555, with a mean BMI of 36·3 kg/m(2) (SD 4·8). 772 were randomly assigned to standard antenatal care and 783 were allocated the behavioural intervention, of which 651 and 629 women, respectively, completed an oral glucose tolerance test. Gestational diabetes was reported in 172 (26%) women in the standard care group compared with 160 (25%) in the intervention group (risk ratio 0·96, 95% CI 0·79-1·16; p=0·68). 61 (8%) of 751 babies in the standard care group were large for gestational age compared with 71 (9%) of 761 in the intervention group (1·15, 0·83-1·59; p=0·40). Thus, the primary outcomes did not differ between groups, despite improvements in some maternal secondary outcomes in the intervention group, including reduced dietary glycaemic load, gestational weight gain, and maternal sum-of-skinfold thicknesses, and increased physical activity. Adverse events included neonatal death (two in the standard care group and three in the intervention group) and fetal death in utero (ten in the standard care group and six in the intervention group). No maternal deaths were reported. Incidence of miscarriage (2% in the standard care group vs 2% in the intervention group), major obstetric haemorrhage (1% vs 3%), and small-for-gestational-age infants (≤5th customised birthweight centile; 6% vs 5%) did not differ between groups.
Interpretation: A behavioural intervention addressing diet and physical activity in women with obesity during pregnancy is not adequate to prevent gestational diabetes, or to reduce the incidence of large-for-gestational-age infants.

Teesson M, Newton NC, Slade T, Chapman C, Birrell L, Mewton L, Mather M, Hides L, McBride N, Allsop S, Andrews G. (2020)MEDLINE-indexed journal, not yet read by usThe Lancet. Digital health · randomised controlled trial Combined prevention for substance use, depression, and anxiety in adolescence: a cluster-randomised controlled trial of a digital online intervention.
Background: Substance use, depression, and anxiety in adolescence are major public health problems requiring new scalable prevention strategies. We aimed to assess the effectiveness of a combined online universal (ie, delivered to all pupils) school-based preventive intervention targeting substance use, depression, and anxiety in adolescence.
Methods: We did a multicentre, cluster-randomised controlled trial in secondary schools in Australia, with pupils in year 8 or 9 (aged 13-14 years). Participating schools were randomly assigned (1:1:1:1) to one of four intervention conditions: (1) Climate Schools-Substance Use, focusing on substance use only; (2) Climate Schools-Mental Health, focusing on depression and anxiety only; (3) Climate Schools-Combined, focusing on the prevention of substance use, depression, and anxiety; or (4) active control. The interventions were delivered in school classrooms in an online delivery format and used a mixture of peer cartoon storyboards and classroom activities that were focused on alcohol, cannabis, anxiety, and depression. The interventions were delivered for 2 years and primary outcomes were knowledge related to alcohol, cannabis, and mental health; alcohol use, including heavy episodic drinking; and depression and anxiety symptoms at 12, 24, and 30 months after baseline. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12613000723785) and an extended follow-up is underway.
Findings: Between Sept 1, 2013, and Feb 28, 2014, we recruited 88 schools (12 391 pupils), of whom 71 schools and 6386 (51·5%) pupils were analysed (17 schools dropped out and 1308 pupils declined to participate). We allocated 18 schools (1739 [27·25%] pupils; 1690 [97·2%] completed at least one follow-up) to the substance use condition, 18 schools (1594 [25·0%] pupils; 1560 [97·9%] completed at least one follow-up) to the mental health condition, 16 schools (1497 [23·4%] pupils; 1443 [96·4%] completed at least one follow-up) to the combined condition, and 19 schools (1556 [23·4%] pupils; 1513 [97·2%] completed at least one follow-up) to the control condition. Compared with controls, the combined intervention group had increased knowledge related to alcohol and cannabis at 12, 24, and 30 months (standardised mean difference [SMD] for alcohol 0·26 [95% CI 0·14 to 0·39] and for cannabis 0·17 [0·06 to 0·28] at 30 months), increased knowledge related to mental health at 24 months (0·17 [0·08 to 0·27]), reduced growth in their odds of drinking and heavy episodic drinking at 12, 24, and 30 months (odds ratio for drinking 0·25 [95% CI 0·12 to 0·51], and for heavy episodic drinking 0·15 [0·04 to 0·58] at 30 months), and reduced increases in anxiety symptoms at 12 and 30 months (SMD -0·12 [95% CI -0·22 to -0·01] at 30 months). We found no difference in symptoms or probable diagnosis of depression. The combined intervention group also showed improvement in alcohol use outcomes compared with the substance use and mental health interventions and improvements in anxiety outcomes when compared with the mental health intervention only.
Interpretation: Combined online prevention of substance use, depression, and anxiety led to increased knowledge of alcohol, cannabis, and mental health, reduced increase in the odds of any drinking and heavy episodic drinking, and reduced symptoms of anxiety over a 30-month period. These findings provide the first evidence of the effectiveness of an online universal school-based preventive intervention targeting substance use, depression, and anxiety in adolescence.

Mikkelsen ME, Christie JD, Lanken PN, Biester RC, Thompson BT, Bellamy SL, Localio AR, Demissie E, Hopkins RO, Angus DC. (2012)MEDLINE-indexed journal, not yet read by usAmerican journal of respiratory and critical care medicine · clinical trial The adult respiratory distress syndrome cognitive outcomes study: long-term neuropsychological function in survivors of acute lung injury.
Rationale: Cognitive and psychiatric morbidity is common and potentially modifiable after acute lung injury (ALI). However, practical measures of neuropsychological function for use in multicenter trials are lacking.
Objectives: To determine whether a validated telephone-based neuropsychological test battery is feasible in a multicenter trial. To determine the frequency and risk factors for long-term neuropsychological impairment.
Methods: As an adjunct study to the Acute Respiratory Distress Syndrome Clinical Trials Network Fluid and Catheter Treatment Trial, we assessed neuropsychological function at 2 and 12 months post-hospital discharge.
Measurements and main results: Of 406 eligible survivors, we approached 261 to participate and 213 consented. We tested 122 subjects at least once, including 102 subjects at 12 months. Memory, verbal fluency, and executive function were impaired in 13% (12 of 92), 16% (15 of 96), and 49% (37 of 76) of long-term survivors. Long-term cognitive impairment was present in 41 of the 75 (55%) survivors who completed cognitive testing. Depression, post-traumatic stress disorder, or anxiety was present in 36% (37 of 102), 39% (40 of 102), and 62% (63 of 102) of long-term survivors. Enrollment in a conservative fluid-management strategy (P = 0.005) was associated with cognitive impairment and lower partial pressure of arterial oxygen during the trial was associated with cognitive (P = 0.02) and psychiatric impairment (P = 0.02).
Conclusions: Neuropsychological function can be assessed by telephone in a multicenter trial. Long-term neuropsychological impairment is common in survivors of ALI. Hypoxemia is a risk factor for long-term neuropsychological impairment. Fluid management strategy is a potential risk factor for long-term cognitive impairment; however, given the select population studied and an unclear mechanism, this finding requires confirmation.

An allied health rehabilitation program for patients following surgery for abdomino-pelvic cancer: a feasibility and pilot clinical study.
Purpose: To investigate the feasibility of conducting a rehabilitation program for patients following surgery for abdomino-pelvic cancer.
Methods: A non-randomised controlled before-and-after study. Patients who had undergone surgery for stage I-III abdomino-pelvic cancer (colorectal, gynaecological or prostate cancer) were recruited. The rehabilitation group (n = 84) received an 8-week, bi-weekly education and exercise program conducted by a physiotherapist, exercise physiologist, health psychologist and dietician, supplemented by exercise diaries and telephone coaching sessions. The comparator group (n = 104) completed postal questionnaires only. Feasibility measures, functional exercise capacity, muscle strength, physical activity levels, pelvic floor symptoms, anxiety and depression, health-related quality of life (HRQoL) and self-efficacy were measured at baseline (time 1), immediately post-intervention (time 2) and at 6 months post-baseline (time 3) and compared within- and between-groups.
Results: The consent rate to the rehabilitation program was 24%. Eighty-one percent of the rehabilitation group attended 85-100% of 16 scheduled sessions. Overall satisfaction with the program was 96%. Functional exercise capacity, handgrip strength in males, bowel symptoms, physical activity levels, depression and HRQoL were significantly improved in the rehabilitation group (p < 0.05) at time 2. The improvements in all these outcomes were sustained at time 3. The rehabilitation group had significantly improved physical activity levels, depression and HRQoL compared with the comparator group at times 2 and 3 (p < 0.05).
Conclusion: Recruitment to this oncology rehabilitation program was more difficult than expected; however, attendance and patient satisfaction were high. This program had positive effects on several important clinical outcomes in patients following abdomino-pelvic cancer treatment.

When weak imagery is worse than none: Core aphantasia and hypophantasia relate differently to mental health, mediated by subjective interoception.
Aphantasia, characterized by absent or reduced visual mental imagery, has been associated with alexithymia and negative mental health outcomes. However, the underlying mechanisms remain unclear. Visual imagery has been proposed as part of an inwardly focused cognitive style that also encompasses interoceptive processing and emotion regulation, suggesting these constructs may be functionally linked. Since mental health is closely tied to interoception, we examined whether interoceptive processing mediates the relationship between imagery ability and mental health. We assessed self-reported imagery vividness (VVIQ), subjective interoceptive accuracy and attention, alexithymia, anxiety, and depression in individuals with aphantasia (n = 153, VVIQ = 16-32) and typical imagers (n = 680, VVIQ = 33-80). Within the aphantasia group, we distinguished core aphantasia (VVIQ 16-23, n = 96) from hypophantasia (VVIQ 24-32, n = 57). The results revealed that individuals with weak imagery (hypophantasia) showed greater alexithymia and worse mental health than those with almost no imagery (core aphantasia), with higher VVIQ predicting poorer outcomes within the aphantasia range. The opposite pattern emerged in typical imagers, where higher VVIQ predicted lower alexithymia and better mental health. Structural equation modeling revealed that these relationships were mediated by alexithymia and the ratio of subjective interoceptive accuracy to attention, with lower ratios (indicating effortful but unsuccessful interoceptive processing) associated with worse outcomes. These findings highlight critical heterogeneity within aphantasia, demonstrating that hypophantasia and core aphantasia have distinct interoceptive and mental health profiles, with implications for understanding the mechanisms linking imagery, bodily awareness, and emotional well-being.

Madigan S, Korczak DJ, Vaillancourt T, Racine N, Hopkins WG, Pador P, Hewitt JMA, AlMousawi B, McDonald S, Neville RD. (2023)MEDLINE-indexed journal, not yet read by usThe lancet. Psychiatry · meta-analysis Comparison of paediatric emergency department visits for attempted suicide, self-harm, and suicidal ideation before and during the COVID-19 pandemic: a systematic review and meta-analysis.
Background: There is a lack of consensus about the effect of the COVID-19 pandemic on the mental health of children and adolescents. We aimed to compare rates of paediatric emergency department visits for attempted suicide, self-harm, and suicidal ideation during the pandemic with those before the pandemic.
Methods: For this systematic review and meta-analysis, we searched MEDLINE, Embase, and PsycINFO for studies published between Jan 1, 2020, and Dec 19, 2022. Studies published in English with data on paediatric (ie, those aged <19 years) emergency department visits before and during the COVID-19 pandemic were included. Case studies and qualitative analyses were excluded. Changes in attempted suicide, self-harm, suicidal ideation, and other mental-illness indicators (eg, anxiety, depression, and psychosis) were expressed as ratios of the rates of emergency department visits during the pandemic compared with those before the pandemic, and we analysed these with a random-effects meta-analysis. This study was registered with PROSPERO, CRD42022341897.
Findings: 10 360 non-duplicate records were retrieved, which yielded 42 relevant studies (with 130 sample-estimates) representing 11·1 million emergency department visits for all indications of children and adolescents across 18 countries. The mean age of the samples of children and adolescents across studies was 11·7 years (SD 3·1, range 5·5-16·3), and there were on average 57·6% girls and 43·4% boys as a proportion of emergency department visits for any health reasons (ie, physical and mental). Only one study had data related to race or ethnicity. There was good evidence of an increase in emergency department visits for attempted suicide during the pandemic (rate ratio 1·22, 90% CI 1·08-1·37), modest evidence of an increase in emergency department visits for suicidal ideation (1·08, 0·93-1·25), and good evidence for only a slight change in self-harm (0·96, 0·89-1·04). Rates of emergency department visits for other mental-illness indications showed very good evidence of a decline (0·81, 0·74-0·89), and paediatric visits for all health indications showed strong evidence of a reduction (0·68, 0·62-0·75). When rates for attempted suicide and suicidal ideation were combined as a single measure, there was good evidence of an increase in emergency department visits among girls (1·39, 1·04-1·88) and only modest evidence of an increase among boys (1·06, 0·92-1·24). Self-harm among older children (mean age 16·3 years, range 13·0-16·3) showed good evidence of an increase (1·18, 1·00-1·39), but among younger children (mean age 9·0 years, range 5·5-12·0) there was modest evidence of a decrease (0·85, 0·70-1·05).
Interpretation: The integration of mental health support within community health and the education system-including promotion, prevention, early intervention, and treatment-is urgently needed to increase the reach of mental health support that can mitigate child and adolescent mental distress. In future pandemics, increased resourcing in some emergency department settings would help to address their expected increase in visits for acute mental distress among children and adolescents.

Prevalence of symptoms of anxiety and depression in patients with inflammatory bowel disease: a systematic review and meta-analysis.
Background: Inflammatory bowel disease (IBD) is a lifelong condition with no cure. Patients with IBD might experience symptoms of common mental disorders such as anxiety and depression because of bidirectional communication via the gut-brain axis and chronicity of symptoms, and because of impaired quality of life and reduced social functioning. However, uncertainties remain about the magnitude of this problem. We aimed to assess prevalence of symptoms of anxiety or depression in adult patients with IBD.
Methods: In this systematic review and meta-analysis, we searched MEDLINE, Embase, Embase Classic, and PsycINFO for papers published from inception to Sept 30, 2020, reporting observational studies that recruited at least 100 adult patients with IBD and that reported prevalence of symptoms of anxiety or depression according to validated screening instruments. We excluded studies that only used a structured interview to assess for these symptoms and studies that did not provide extractable data. We extracted data from published study reports and calculated pooled prevalences of symptoms of anxiety and depression, odds ratios (OR), and 95% CIs.
Findings: Of 5544 studies identified, 77 fulfilled the eligibility criteria, including 30 118 patients in total. Overall, pooled prevalence of anxiety symptoms was 32·1% (95% CI 28·3-36·0) in 58 studies (I2=96·9%) and pooled prevalence of depression symptoms was 25·2% (22·0-28·5) in 75 studies (I2=97·6%). In studies that reported prevalence of anxiety or depression in patients with Crohn's disease and ulcerative colitis within the same study population, patients with Crohn's disease had higher odds of anxiety symptoms (OR 1·2, 95% CI 1·1-1·4) and depression symptoms (1·2, 1·1-1·4) than patients with ulcerative colitis. Overall, women with IBD were more likely to have symptoms of anxiety than were men with IBD (pooled prevalence 33·8% [95% CI 26·5-41·5] for women vs 22·8% [18·7-27·2] for men; OR 1·7 [95% CI 1·2-2·3]). They were also more likely to have symptoms of depression than men were (pooled prevalence 21·2% [95% CI 15·4-27·6] for women vs 16·2% [12·6-20·3] for men; OR 1·3 [95% CI 1·0-1·8]). The prevalence of symptoms of anxiety (57·6% [95% CI 38·6-75·4]) or depression (38·9% [26·2-52·3]) was higher in patients with active IBD than in patients with inactive disease (38·1% [30·9-45·7] for anxiety symptoms and 24·2% [14·7-35·3] for depression symptoms; ORs 2·5 [95% CI 1·5-4·1] for anxiety and 3·1 [1·9-4·9] for depression).
Interpretation: There is a high prevalence of symptoms of anxiety and depression in patients with IBD, with up to a third of patients affected by anxiety symptoms and a quarter affected by depression symptoms. Prevalence was also increased in patients with active disease: half of these patients met criteria for anxiety symptoms and a third met criteria for depression symptoms. Encouraging gastroenterologists to screen for and treat these disorders might improve outcomes for patients with IBD.

(2018)MEDLINE-indexed journal, not yet read by usLancet (London, England) · systematic review Comparative efficacy and acceptability of 21 antidepressant drugs for the acute treatment of adults with major depressive disorder: a systematic review and network meta-analysis.
Background: Major depressive disorder is one of the most common, burdensome, and costly psychiatric disorders worldwide in adults. Pharmacological and non-pharmacological treatments are available; however, because of inadequate resources, antidepressants are used more frequently than psychological interventions. Prescription of these agents should be informed by the best available evidence. Therefore, we aimed to update and expand our previous work to compare and rank antidepressants for the acute treatment of adults with unipolar major depressive disorder.
Methods: We did a systematic review and network meta-analysis. We searched Cochrane Central Register of Controlled Trials, CINAHL, Embase, LILACS database, MEDLINE, MEDLINE In-Process, PsycINFO, the websites of regulatory agencies, and international registers for published and unpublished, double-blind, randomised controlled trials from their inception to Jan 8, 2016. We included placebo-controlled and head-to-head trials of 21 antidepressants used for the acute treatment of adults (≥18 years old and of both sexes) with major depressive disorder diagnosed according to standard operationalised criteria. We excluded quasi-randomised trials and trials that were incomplete or included 20% or more of participants with bipolar disorder, psychotic depression, or treatment-resistant depression; or patients with a serious concomitant medical illness. We extracted data following a predefined hierarchy. In network meta-analysis, we used group-level data. We assessed the studies' risk of bias in accordance to the Cochrane Handbook for Systematic Reviews of Interventions, and certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. Primary outcomes were efficacy (response rate) and acceptability (treatment discontinuations due to any cause). We estimated summary odds ratios (ORs) using pairwise and network meta-analysis with random effects. This study is registered with PROSPERO, number CRD42012002291.
Findings: We identified 28 552 citations and of these included 522 trials comprising 116 477 participants. In terms of efficacy, all antidepressants were more effective than placebo, with ORs ranging between 2·13 (95% credible interval [CrI] 1·89-2·41) for amitriptyline and 1·37 (1·16-1·63) for reboxetine. For acceptability, only agomelatine (OR 0·84, 95% CrI 0·72-0·97) and fluoxetine (0·88, 0·80-0·96) were associated with fewer dropouts than placebo, whereas clomipramine was worse than placebo (1·30, 1·01-1·68). When all trials were considered, differences in ORs between antidepressants ranged from 1·15 to 1·55 for efficacy and from 0·64 to 0·83 for acceptability, with wide CrIs on most of the comparative analyses. In head-to-head studies, agomelatine, amitriptyline, escitalopram, mirtazapine, paroxetine, venlafaxine, and vortioxetine were more effective than other antidepressants (range of ORs 1·19-1·96), whereas fluoxetine, fluvoxamine, reboxetine, and trazodone were the least efficacious drugs (0·51-0·84). For acceptability, agomelatine, citalopram, escitalopram, fluoxetine, sertraline, and vortioxetine were more tolerable than other antidepressants (range of ORs 0·43-0·77), whereas amitriptyline, clomipramine, duloxetine, fluvoxamine, reboxetine, trazodone, and venlafaxine had the highest dropout rates (1·30-2·32). 46 (9%) of 522 trials were rated as high risk of bias, 380 (73%) trials as moderate, and 96 (18%) as low; and the certainty of evidence was moderate to very low.
Interpretation: All antidepressants were more efficacious than placebo in adults with major depressive disorder. Smaller differences between active drugs were found when placebo-controlled trials were included in the analysis, whereas there was more variability in efficacy and acceptability in head-to-head trials. These results should serve evidence-based practice and inform patients, physicians, guideline developers, and policy makers on the relative merits of the different antidepressants.

(2017)MEDLINE-indexed journal, not yet read by usScientific reports · randomised controlled trial Vagus Nerve Stimulation Paired with Tones for the Treatment of Tinnitus: A Prospective Randomized Double-blind Controlled Pilot Study in Humans.
The aim of the pilot study was to evaluate the effect of Vagus Nerve Stimulation (VNS) paired with sounds in chronic tinnitus patients. All participants were implanted and randomized to a paired VNS (n = 16) or control (n = 14) group. After 6 weeks of home therapy, all participants received paired VNS. The device was used on 96% of days with good compliance. After 6 weeks, the paired VNS group improved on the Tinnitus Handicap Inventory (THI) (p = 0.0012) compared to controls (p = 0.1561). The between-group difference was 10.3% (p = 0.3393). Fifty percent of the participants in the paired VNS group showed clinically meaningful improvements compared to 28% in controls. At one year, 50% of participants had a clinically meaningful response. The therapy had greater benefits for participants with tonal and non-blast induced tinnitus at the end of 6 (24.3% vs. 2%, p = 0.05) and 12 weeks (34% vs. 2%, p = 0.004) compared to controls with 80% and 70% responding at 6 months and 1 year, respectively. Adverse effects were mild and well-tolerated and the therapy had a similar safety profile to VNS for epilepsy. VNS paired with tones may be effective for a subgroup of tinnitus patients and provides impetus for a larger pivotal study.

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

(2024)MEDLINE-indexed journal, not yet read by usThe Lancet. Neurology · randomised controlled trial Comparative effectiveness of cognitive behavioural therapy, modafinil, and their combination for treating fatigue in multiple sclerosis (COMBO-MS): a randomised, statistician-blinded, parallel-arm trial.
Background: Fatigue is one of the most disabling symptoms reported by people with multiple sclerosis. Although behavioural and pharmacological interventions might be partly beneficial, their combined effects have not been evaluated for multiple sclerosis fatigue, or examined with sufficient consideration of characteristics that might affect treatment response. In this comparative effectiveness research trial, we compared the effectiveness of cognitive behavioural therapy (CBT), modafinil, and their combination for treating multiple sclerosis fatigue.
Methods: This randomised, analyst-blinded, parallel-arm, comparative effectiveness trial was done at two universities in the USA. Adults (aged ≥18 years) with multiple sclerosis and problematic fatigue (Fatigue Severity Scale [FSS] score ≥4) were randomly assigned (1:1:1), using a web-based treatment assignment system with minimisation, to receive CBT, modafinil, or both for 12 weeks. Statisticians were masked to group assignment, but participants, study neurologists, CBT interventionalists, and coordinators were not masked to treatment assignment. The primary outcome was the change in Modified Fatigue Impact Scale (MFIS) from baseline to 12 weeks, assessed using multiple linear regression, adjusted for age, sex, study site, anxiety, pain, baselines MFIS score, and physical activity. Analyses were done by intent to treat. The trial was registered with clinicaltrials.gov, NCT03621761, and is completed.
Findings: Between Nov 15, 2018, and June 2, 2021, 336 participants were randomly assigned treatment (114 assigned to CBT, 114 assigned to modafinil, and 108 assigned to combination therapy). At 12 weeks, CBT (n=103), modafinil (n=107), and combination therapy (n=102) were associated with clinically meaningful within-group MFIS reductions of 15·20 (SD 11·90), 16·90 (15·90), and 17·30 (16·20) points, respectively. Change in MFIS scores from baseline to 12 weeks did not differ between groups: relative to combination therapy, the adjusted total mean difference in MFIS change score was 1·88 (95% CI -2·21 to 5·96) for CBT and 1·20 (-2·83 to 5·23) for modafinil. Most common adverse events for modafinil-containing treatment groups included insomnia (eight [7%] for modafinil and eight [7%] for combination therapy) and anxiety (three [3%] for modafinil and nine [8%] for combination therapy).
Interpretation: Modafinil, CBT, and combination therapy were associated with similar reductions in the effects of multiple sclerosis fatigue at 12 weeks. Combination therapy was not associated with augmented improvement compared with the individual interventions. Further research is needed to determine whether effects of these interventions on multiple sclerosis-related fatigue is influenced by sleep hygiene and sleepiness. No serious adverse events related to the study drug were encountered.

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

(2020)MEDLINE-indexed journal, not yet read by usHealth technology assessment (Winchester, England) · randomised controlled trial A web-based, peer-supported self-management intervention to reduce distress in relatives of people with psychosis or bipolar disorder: the REACT RCT.
Background: Relatives caring for people with severe mental health problems find information and emotional support hard to access. Online support for self-management offers a potential solution.
Objective: The objective was to determine the clinical effectiveness and cost-effectiveness of an online supported self-management tool for relatives: the Relatives' Education And Coping Toolkit (REACT).
Design and setting: This was a primarily online (UK), single-blind, randomised controlled trial, comparing REACT plus a resource directory and treatment as usual with the resource directory and treatment as usual only, by measuring user distress and other well-being measures at baseline and at 12 and 24 weeks.
Participants: A total of 800 relatives of people with severe mental health problems across the UK took part; relatives who were aged ≥ 16 years, were experiencing high levels of distress, had access to the internet and were actively seeking help were recruited.
Intervention: REACT comprised 12 psychoeducation modules, peer support through a group forum, confidential messaging and a comprehensive resource directory of national support. Trained relatives moderated the forum and responded to messages.
Main outcome measure: The main outcome was the level of participants' distress, as measured by the General Health Questionnaire-28 items.
Results: Various online and offline strategies, including social media, directed potential participants to the website. Participants were randomised to one of two arms: REACT plus the resource directory (n = 399) or the resource directory only (n = 401). Retention at 24 weeks was 75% (REACT arm, n = 292; resource directory-only arm, n = 307). The mean scores for the General Health Questionnaire-28 items reduced substantially across both arms over 24 weeks, from 40.2 (standard deviation 14.3) to 30.5 (standard deviation 15.6), with no significant difference between arms (mean difference -1.39, 95% confidence interval -3.60 to 0.83; p = 0.22). At 12 weeks, the General Health Questionnaire-28 items scores were lower in the REACT arm than in the resource directory-only arm (-2.08, 95% confidence interval -4.14 to -0.03; p = 0.027), but this finding is likely to be of limited clinical significance. Accounting for missing data, which were associated with higher distress in the REACT arm (0.33, 95% confidence interval -0.27 to 0.93; p = 0.279), in a longitudinal model, there was no significant difference between arms over 24 weeks (-0.56, 95% confidence interval -2.34 to 1.22; p = 0.51). REACT cost £142.95 per participant to design and deliver (£62.27 for delivery only), compared with £0.84 for the resource directory only. A health economic analysis of NHS, health and Personal Social Services outcomes found that REACT has higher costs (£286.77), slightly better General Health Questionnaire-28 items scores (incremental General Health Questionnaire-28 items score adjusted for baseline, age and gender: -1.152, 95% confidence interval -3.370 to 1.065) and slightly lower quality-adjusted life-year gains than the resource directory only; none of these differences was statistically significant. The median time spent online was 50.8 minutes (interquartile range 12.4-172.1 minutes) for REACT, with no significant association with outcome. Participants reported finding REACT a safe, confidential environment (96%) and reported feeling supported by the forum (89%) and the REACT supporters (86%). No serious adverse events were reported.
Limitations: The sample comprised predominantly white British females, 25% of participants were lost to follow-up and dropout in the REACT arm was not random.
Conclusions: An online self-management support toolkit with a moderated group forum is acceptable to relatives and, compared with face-to-face programmes, offers inexpensive, safe delivery of National Institute for Health and Care Excellence-recommended support to engage relatives as peers in care delivery. However, currently, REACT plus the resource directory is no more effective at reducing relatives' distress than the resource directory only.
Future work: Further research in improving the effectiveness of online carer support interventions is required.

Psychiatry · randomised controlled trial Cognitive behavioural therapy for adults with dissociative seizures (CODES): a pragmatic, multicentre, randomised controlled trial.
Background: Dissociative seizures are paroxysmal events resembling epilepsy or syncope with characteristic features that allow them to be distinguished from other medical conditions. We aimed to compare the effectiveness of cognitive behavioural therapy (CBT) plus standardised medical care with standardised medical care alone for the reduction of dissociative seizure frequency.
Methods: In this pragmatic, parallel-arm, multicentre randomised controlled trial, we initially recruited participants at 27 neurology or epilepsy services in England, Scotland, and Wales. Adults (≥18 years) who had dissociative seizures in the previous 8 weeks and no epileptic seizures in the previous 12 months were subsequently randomly assigned (1:1) from 17 liaison or neuropsychiatry services following psychiatric assessment, to receive standardised medical care or CBT plus standardised medical care, using a web-based system. Randomisation was stratified by neuropsychiatry or liaison psychiatry recruitment site. The trial manager, chief investigator, all treating clinicians, and patients were aware of treatment allocation, but outcome data collectors and trial statisticians were unaware of treatment allocation. Patients were followed up 6 months and 12 months after randomisation. The primary outcome was monthly dissociative seizure frequency (ie, frequency in the previous 4 weeks) assessed at 12 months. Secondary outcomes assessed at 12 months were: seizure severity (intensity) and bothersomeness; longest period of seizure freedom in the previous 6 months; complete seizure freedom in the previous 3 months; a greater than 50% reduction in seizure frequency relative to baseline; changes in dissociative seizures (rated by others); health-related quality of life; psychosocial functioning; psychiatric symptoms, psychological distress, and somatic symptom burden; and clinical impression of improvement and satisfaction. p values and statistical significance for outcomes were reported without correction for multiple comparisons as per our protocol. Primary and secondary outcomes were assessed in the intention-to-treat population with multiple imputation for missing observations. This trial is registered with the International Standard Randomised Controlled Trial registry, ISRCTN05681227, and ClinicalTrials.gov, NCT02325544.
Findings: Between Jan 16, 2015, and May 31, 2017, we randomly assigned 368 patients to receive CBT plus standardised medical care (n=186) or standardised medical care alone (n=182); of whom 313 had primary outcome data at 12 months (156 [84%] of 186 patients in the CBT plus standardised medical care group and 157 [86%] of 182 patients in the standardised medical care group). At 12 months, no significant difference in monthly dissociative seizure frequency was identified between the groups (median 4 seizures [IQR 0-20] in the CBT plus standardised medical care group vs 7 seizures [1-35] in the standardised medical care group; estimated incidence rate ratio [IRR] 0·78 [95% CI 0·56-1·09]; p=0·144). Dissociative seizures were rated as less bothersome in the CBT plus standardised medical care group than the standardised medical care group (estimated mean difference -0·53 [95% CI -0·97 to -0·08]; p=0·020). The CBT plus standardised medical care group had a longer period of dissociative seizure freedom in the previous 6 months (estimated IRR 1·64 [95% CI 1·22 to 2·20]; p=0·001), reported better health-related quality of life on the EuroQoL-5 Dimensions-5 Level Health Today visual analogue scale (estimated mean difference 6·16 [95% CI 1·48 to 10·84]; p=0·010), less impairment in psychosocial functioning on the Work and Social Adjustment Scale (estimated mean difference -4·12 [95% CI -6·35 to -1·89]; p<0·001), less overall psychological distress than the standardised medical care group on the Clinical Outcomes in Routine Evaluation-10 scale (estimated mean difference -1·65 [95% CI -2·96 to -0·35]; p=0·013), and fewer somatic symptoms on the modified Patient Health Questionnaire-15 scale (estimated mean difference -1·67 [95% CI -2·90 to -0·44]; p=0·008). Clinical improvement at 12 months was greater in the CBT plus standardised medical care group than the standardised medical care alone group as reported by patients (estimated mean difference 0·66 [95% CI 0·26 to 1·04]; p=0·001) and by clinicians (estimated mean difference 0·47 [95% CI 0·21 to 0·73]; p<0·001), and the CBT plus standardised medical care group had greater satisfaction with treatment than did the standardised medical care group (estimated mean difference 0·90 [95% CI 0·48 to 1·31]; p<0·001). No significant differences in patient-reported seizure severity (estimated mean difference -0·11 [95% CI -0·50 to 0·29]; p=0·593) or seizure freedom in the last 3 months of the study (estimated odds ratio [OR] 1·77 [95% CI 0·93 to 3·37]; p=0·083) were identified between the groups. Furthermore, no significant differences were identified in the proportion of patients who had a more than 50% reduction in dissociative seizure frequency compared with baseline (OR 1·27 [95% CI 0·80 to 2·02]; p=0·313). Additionally, the 12-item Short Form survey-version 2 scores (estimated mean difference for the Physical Component Summary score 1·78 [95% CI -0·37 to 3·92]; p=0·105; estimated mean difference for the Mental Component Summary score 2·22 [95% CI -0·30 to 4·75]; p=0·084), the Generalised Anxiety Disorder-7 scale score (estimated mean difference -1·09 [95% CI -2·27 to 0·09]; p=0·069), and the Patient Health Questionnaire-9 scale depression score (estimated mean difference -1·10 [95% CI -2·41 to 0·21]; p=0·099) did not differ significantly between groups. Changes in dissociative seizures (rated by others) could not be assessed due to insufficient data. During the 12-month period, the number of adverse events was similar between the groups: 57 (31%) of 186 participants in the CBT plus standardised medical care group reported 97 adverse events and 53 (29%) of 182 participants in the standardised medical care group reported 79 adverse events.
Interpretation: CBT plus standardised medical care had no statistically significant advantage compared with standardised medical care alone for the reduction of monthly seizures. However, improvements were observed in a number of clinically relevant secondary outcomes following CBT plus standardised medical care when compared with standardised medical care alone. Thus, adults with dissociative seizures might benefit from the addition of dissociative seizure-specific CBT to specialist care from neurologists and psychiatrists. Future work is needed to identify patients who would benefit most from a dissociative seizure-specific CBT approach.

Head-to-head comparison of accuracy of a rapid point-of-care HIV test with oral versus whole-blood specimens: a systematic review and meta-analysis.
Background: The focus on prevention strategies aimed at curbing the HIV epidemic is growing, and therefore screening for HIV has again taken centre stage. Our aim was to establish whether a convenient, non-invasive, HIV test that uses oral fluid was accurate by comparison with the same test with blood-based specimens.
Methods: We did a systematic review and meta-analysis to compare the diagnostic accuracy of a rapid HIV-antibody-based point-of-care test (Oraquick advance rapid HIV-1/2, OraSure Technologies Inc, PA, USA) when used with oral versus blood-based specimens in adults. We searched five databases of published work and databases of five key HIV conferences. Studies we deemed eligible were those focused on adults at risk of HIV; we excluded studies in children, in co-infected populations, with self-reported inferior reference standards, and with incomplete reporting of key data items. We assessed the diagnostic accuracy of testing with oral and blood-based specimens with bivariate regression analysis. We computed positive predictive values (PPVs) in high-prevalence and low-prevalence settings with Bayesian methods.
Findings: In a direct head-to-head comparison of studies, we identified a pooled sensitivity about 2% lower in oral (98·03%, 95% CI 95·85-99·08) than in blood-based specimens (99·68%, 97·31-99·96), but similar specificity (oral 99·74%, 99·47-99·88; blood 99·91%, 99·84-99·95). Negative likelihood ratios were small and similar (oral 0·019, 0.009-0·040; blood 0·003, 0·001-0·034), but positive likelihood ratios differed (oral 383·37, 183·87-799·31; blood 1105·16, 633·14-2004·37). Although in high-prevalence settings PPVs were similar (oral 98·65%, 95% credible interval 85·71-99·94; blood 98·50, 93·10-99·79), in low-prevalence settings PPVs were lower for oral (88·55%, 77·31-95·87) than blood (97·65%, 95·48-99·09) specimens.
Interpretation: Although Oraquick had a high PPV in high-prevalence settings in oral specimens, the slightly lower sensitivity and PPV in low-prevalence settings in oral specimens should be carefully reviewed when planning worldwide expanded initiatives with this popular test.

Surgical decompression for space-occupying cerebral infarction (the Hemicraniectomy After Middle Cerebral Artery infarction with Life-threatening Edema Trial [HAMLET]): a multicentre, open, randomised trial.
Background: Patients with space-occupying hemispheric infarctions have a poor prognosis, with case fatality rates of up to 80%. In a pooled analysis of randomised trials, surgical decompression within 48 h of stroke onset reduced case fatality and improved functional outcome; however, the effect of surgery after longer intervals is unknown. The aim of HAMLET was to assess the effect of decompressive surgery within 4 days of the onset of symptoms in patients with space-occupying hemispheric infarction.
Methods: Patients with space-occupying hemispheric infarction were randomly assigned within 4 days of stroke onset to surgical decompression or best medical treatment. The primary outcome measure was the modified Rankin scale (mRS) score at 1 year, which was dichotomised between good (0-3) and poor (4-6) outcome. Other outcome measures were the dichotomy of mRS score between 4 and 5, case fatality, quality of life, and symptoms of depression. Analysis was by intention to treat. This trial is registered, ISRCTN94237756.
Findings: Between November, 2002, and October, 2007, 64 patients were included; 32 were randomly assigned to surgical decompression and 32 to best medical treatment. Surgical decompression had no effect on the primary outcome measure (absolute risk reduction [ARR] 0%, 95% CI -21 to 21) but did reduce case fatality (ARR 38%, 15 to 60). In a meta-analysis of patients in DECIMAL (DEcompressive Craniectomy In MALignant middle cerebral artery infarction), DESTINY (DEcompressive Surgery for the Treatment of malignant INfarction of the middle cerebral arterY), and HAMLET who were randomised within 48 h of stroke onset, surgical decompression reduced poor outcome (ARR 16%, -0.1 to 33) and case fatality (ARR 50%, 34 to 66).
Interpretation: Surgical decompression reduces case fatality and poor outcome in patients with space-occupying infarctions who are treated within 48 h of stroke onset. There is no evidence that this operation improves functional outcome when it is delayed for up to 96 h after stroke onset. The decision to perform the operation should depend on the emphasis patients and relatives attribute to survival and dependency.

Background: Cancer survival has improved in the past 20 years, affecting the long-term risk of mood disorders. We assessed whether depression and anxiety are more common in long-term survivors of cancer compared with their spouses and with healthy controls.
Methods: We systematically searched Medline, PsycINFO, Embase, Science Direct, Ingenta Select, Ovid, and Wiley Interscience for reports about the prevalence of mood disorders in patients diagnosed with cancer at least 2 years previously. We also searched the records of the International Psycho-oncology Society and for reports that cited relevant references. Three investigators independently extracted primary data. We did a random-effects meta-analysis of the prevalences of depression and anxiety in cancer patients compared with spouses and healthy controls.
Findings: Our search returned 144 results, 43 were included in the main analysis: for comparisons with healthy controls, 16 assessed depression and ten assessed anxiety; of the comparisons with spouses, 12 assessed depression and five assessed anxiety. The prevalence of depression was 11·6% (95% CI 7·7-16·2) in the pooled sample of 51 381 cancer survivors and 10·2% (8·0-12·6) in 217 630 healthy controls (pooled relative risk [RR] 1·11, 95% CI 0·96-1·27; p=0·17). The prevalence of anxiety was 17·9% (95% CI 12·8-23·6) in 48 964 cancer survivors and 13·9% (9·8-18·5) in 226 467 healthy controls (RR 1·27, 95% CI 1·08-1·50; p=0·0039). Neither the prevalence of depression (26·7% vs 26·3%; RR 1·01, 95% CI 0·86-1·20; p=0·88) nor the prevalence of anxiety (28·0% vs 40·1%; RR 0·71, 95% CI 0·44-1·14; p=0·16) differed significantly between cancer patients and their spouses.
Interpretation: Our findings suggest that anxiety, rather than depression, is most likely to be a problem in long-term cancer survivors and spouses compared with healthy controls. Efforts should be made to improve recognition and treatment of anxiety in long-term cancer survivors and their spouses.

Disasters and youth: a meta-analytic examination of posttraumatic stress.
Objective: Meta-analyze the literature on posttraumatic stress (PTS) symptoms in youths post-disaster.
Method: Meta-analytic synthesis of the literature (k = 96 studies; Ntotal = 74,154) summarizing the magnitude of associations between disasters and youth PTS, and key factors associated with variations in the magnitude of these associations. We included peer-reviewed studies published prior to 1/1/2009 that quantitatively examined youth PTS (≤ 18 years at event) after a distinct and identifiable disaster.
Results: Despite variability across studies, disasters had a significant effect on youth PTS (small-to-medium magnitude; rpooled = .19, SEr = .03; d = 0.4). Female gender (rpooled = .14), higher death toll (disasters of death toll ≤ 25: rpooled = .09; vs. disasters with ≥ 1,000 deaths: rpooled = .22), child proximity (rpooled = .33), personal loss (rpooled = .16), perceived threat (rpooled = .34), and distress (rpooled = .38) at time of event were each associated with increased PTS. Studies conducted within 1 year post-disaster, studies that used established measures, and studies that relied on child-report data identified a significant effect.
Conclusion: Youths are vulnerable to appreciable PTS after disaster, with pre-existing child characteristics, aspects of the disaster experience, and study methodology each associated with variations in the effect magnitude. Findings underscore the importance of measurement considerations in post-disaster research. Areas in need of research include the long-term impact of disasters, disaster-related media exposure, prior trauma and psychopathology, social support, ethnicity/race, prejudice, parental psychopathology, and the effects of disasters in developing regions of the world. Policy and clinical implications are discussed.

The Effectiveness of Cognitive Behavior Therapy for Borderline Personality Disorder: Results from the Borderline Personality Disorder Study of Cognitive Therapy (BOSCOT) Trial
The outcome of a randomized controlled trial of cognitive behavior therapy in addition to treatment as usual (CBT plus TAU) compared with TAU alone (TAU) in one hundred and six participants meeting diagnostic criteria for borderline personality disorder is described. We anticipated that CBT plus TAU would decrease the number of participants with in-patient psychiatric hospitalizations or accident and emergency room contact or suicidal acts over twelve months treatment and twelve months follow-up, compared with TAU. We also anticipated that CBT plus TAU would lead to improvement in a range of secondary outcomes of mental health and social functioning compared to TAU. Of the 106 participants randomized, follow-up data on 102 (96%) was obtained at two years. Those randomized to CBT were offered an average of 27 sessions over 12 months and attended on average 16 (range 0 to 35). We found that the global odds ratio of a participant in the CBT plus TAU group compared with the TAU alone group having any of the outcomes of a suicidal act, in-patient hospitalization, or accident and emergency contact in the 24 months following randomization was 0.86 (95% confidence interval [CI] 0.45 to 1.66, p = 0.66). The corresponding global odds ratio, excluding accident and emergency room contact, was 0.75 (95% CI 0.37 to 1.54, p = 0.44). In terms of the number of suicidal acts, there was a significant reduction over the two years in favor of CBT plus TAU over TAU, with a mean difference of -0.91 (95% CI -1.67 to -0.15, p = 0.020). Across both treatment arms there was gradual and sustained improvement in both primary and secondary outcomes, with evidence of benefit for the addition of CBT on the positive symptom distress index at one year, and on state anxiety, dysfunctional beliefs and the quantity of suicidal acts at two year follow-up. CBT can deliver clinically important changes in relatively few clinical sessions in real clinical settings.

The effect of a social work intervention to enhance advance care planning documentation in the nursing home.
Objectives: To assess the effect of a multicomponent advance care planning intervention directed at nursing home social workers on identification and documentation of preferences for medical treatments and on patient outcomes.
Design: Controlled clinical trial.
Setting: New York City nursing home.
Participants: One hundred thirty-nine newly admitted long-term care residents.
Intervention: Nursing home social workers were randomized to the intervention or control groups. The intervention consisted of baseline education in advance care planning that incorporated small-group workshops and role play/practice sessions for intervention social workers; structured advance care planning discussions with residents and their proxies at admission, after any change in clinical status, and at yearly intervals; formal structured review of residents' goals of care at preexisting regular team meetings; "flagging" of advance directives on nursing home charts; and feedback to individual healthcare providers of the congruence of care they provided and the preferences specified in the advance care planning process. Control social workers received an educational training session on New York State law regarding advance directives but no additional training or interventions. Subjects were enrolled from January 9, 2001 through May 25, 2003 and followed for 6 months after enrollment.
Measurements: Nursing home chart documentation of advance directives (healthcare proxies, living wills) and do-not-resuscitate orders; preferences for artificial nutrition and hydration, intravenous antibiotics, and hospitalization; and concordance of treatments received with documented preferences were compared for residents assigned to intervention and control social workers.
Results: Intervention residents were significantly more likely than residents in the control group to have their preferences regarding cardiopulmonary resuscitation (40% vs 20%, P=.005), artificial nutrition and hydration (47% vs 9%, P<.01), intravenous antibiotics (44% vs 9%, P<.01), and hospitalization (49% vs 16%, P<.01) documented in the nursing home chart. Control residents were significantly more likely than intervention residents to receive treatments discordant with their prior stated wishes. Two of 49 (5%) intervention residents received a treatment in conflict with their prior stated wishes (one hospitalization, one episode of intravenous antibiotics), compared with 17 of 96 (18%) control patients (P=.04).
Conclusion: This generalizable intervention directed at nursing home social workers significantly improved the documentation and identification of patients' wishes regarding common life-sustaining treatments and resulted in a higher concordance between patients' prior stated wishes and treatments received.

Volunteering: a physical activity intervention for older adults--The Experience Corps program in Baltimore.
There is compelling evidence supporting the benefits of increased regular physical activity in older adults. The Experience Corps program in Baltimore MD was designed in part as a community based approach to increasing physical activity that would also appeal to older adults who have historically not utilized health promotion programs. The Baltimore Experience Corps program places older volunteers in public elementary schools for 15 h a week in roles designed to improve the academic outcomes of children and, simultaneously, increase the physical, cognitive and social activity of volunteers. This paper reports on the change in physical activity levels among older adults associated with participation in the Baltimore Experience Corps. In a pilot randomized controlled evaluation, older adults were randomly assigned to Experience Corps (EC participants) or a waiting list control group. Ages ranged from 59-86 years, 96% were African American, 94% were women, and 84% had annual incomes less than $15,000. EC participants were required to serve >/=15 h a week. At follow-up after 4-8 months, an analysis of 113 randomized volunteers revealed 53% of the EC participants were more active than the previous year by self-report, as compared to 23% of the controls (p<0.01). When adjusted for age, gender and education, there was a trend toward increased physical activity in the EC participants as calculated by a kilocalorie per week increase of 40%, versus a 16% decrease in the controls (p=0.49). EC participants who reported "low activity" at baseline experienced an average 110% increase in their physical activity at follow-up. Among the controls who were in the "low activity" group at baseline, there was, on average, only a 12% increase in physical activity (p=0.03). Among those who were previously active, there was no significant difference (p=0.30). The pilot results suggest that a high intensity volunteer program that is designed as a health promotion intervention can lead, in the short-term, to significant improvements in the level of physical activity of previously inactive older adult volunteers.

A randomised controlled trial of cognitive behaviour therapy in adolescents with major depression treated by selective serotonin reuptake inhibitors. The ADAPT trial
OBJECTIVES: To determine if, in the short term, depressed adolescents attending routine NHS Child and Adolescent Mental Health Services (CAMHS), and receiving ongoing active clinical care, treatment with selective serotonin reuptake inhibitors (SSRIs) plus cognitive behaviour therapy (CBT) compared with SSRI alone, results in better healthcare outcomes. DESIGN: A pragmatic randomised controlled trial (RCT) was conducted on depressed adolescents attending CAMHS who had not responded to a psychosocial brief initial intervention (BII) prior to randomisation. SETTING: Six English CAMHS participated in the study. PARTICIPANTS: A total of 208 patients aged between 11 and 17 years were recruited and randomised. INTERVENTIONS: All participants received active routine clinical care in a CAMHS outpatient setting and an SSRI and half were offered CBT. MAIN OUTCOME MEASURES: The duration of the trial was a 12-week treatment phase, followed by a 16-week maintenance phase. Follow-up assessments were at 6, 12 and 28 weeks. The primary outcome measure was the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA). Secondary outcome measures were self-report depressive symptoms, interviewer-rated depressive signs and symptoms, interviewer-rated psychosocial impairment and clinical global impression of response to treatment. Information on resource use was collected in interview at baseline and at the 12- and 28-week follow-up assessments using the Child and Adolescent Service Use Schedule (CA-SUS). RESULTS: Of the 208 patients randomised, 200 (96%) completed the trial to the primary end-point at 12 weeks. By the 28-week follow-up, 174 (84%) participants were re-evaluated. Overall, 193 (93%) participants had been assessed at one or more time points. Clinical characteristics indicated that the trial was conducted on a severely depressed group. There was significant recovery at all time points in both arms. The findings demonstrated no difference in treatment effectiveness for SSRI + CBT over SSRI only for the primary or secondary outcome measures at any time point. This lack of difference held when baseline and treatment characteristics where taken into account (age, sex, severity, co-morbid characteristics, quality and quantity of CBT treatment, number of clinic attendances). The SSRI + CBT group was somewhat more expensive over the 28 weeks than the SSRI-only group (p=0.057) and no more cost-effective. Over the trial period there was on average a decrease in suicidal thoughts and self-harm compared with levels recorded at baseline. There was no significant increase in disinhibition, irritability and violence compared with levels at baseline. Around 20% (n=40) of patients in the trial were non-responders. Of these, 17 (43%) showed no improvement by 28 weeks and 23 (57%) were considered minimally (n=10) or moderately to severely worse (n=13). CONCLUSIONS: For moderately to severely depressed adolescents who are non-responsive to a BII, the addition of CBT to fluoxetine plus routine clinical care does not improve outcome or confer protective effects against adverse events and is not cost-effective. SSRIs (mostly fluoxetine) are not likely to result in harmful adverse effects. The findings are broadly consistent with existing guidelines on the treatment of moderate to severe depression. Modification is advised for those presenting with moderate (6-8 symptoms) to severe depressions (>8 symptoms) and in those with either overt suicidal risk and/or high levels of personal impairment. In such cases, the time allowed for response to psychosocial interventions should be no more than 2-4 weeks, after which fluoxetine should be prescribed. Further research should focus on evaluating the efficacy of specific psychological treatments against brief psychological intervention, determining the characteristics of patients with severe depression who are non-responsive to fluoxetine, relapse prevention in severe depression and improving tools for determining treatment responders and non-responders.

What Are the Minimal and Substantial Improvements in the HOOS and KOOS and JR Versions After Total Joint Replacement?
Background: Patient-reported outcome measures (PROMs) are a gold standard for measuring therapeutic outcomes in research. Extending their use to inform clinical care decisions, determine the appropriateness of therapeutic choices, and assess healthcare quality is attractive but will require our professional community to establish valid estimates of minimal and substantial clinical improvements.
Questions/purposes: The purposes of this study were (1) to assess the validity of estimates for the minimal clinically important difference (MCID) calculated using distribution- and anchor-based methods by determining whether they exceed the minimal detectable change (MDC) for the Hip Disability and Osteoarthritis Outcome Score (HOOS) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) domains, the HOOS, joint replacement (JR) and the KOOS, JR among patients who underwent THA or TKA; (2) to determine substantial clinical benefit thresholds for the HOOS and KOOS domains, the HOOS, JR, and the KOOS, JR among patients who underwent THA or TKA; and (3) to assess the proportions of patients who underwent THA or TKA who achieved an MCID for the HOOS and KOOS domains, HOOS, JR, and KOOS, JR based on distribution-based and anchor-based methods as well as the percentages of patients who achieved substantial clinical benefit using the anchor-based method.
Methods: Medicare patients enrolled in our institutional joint replacement registry who subsequently underwent THA (n = 2323) or TKA (n = 2630) between 2007 and 2012 completed HOOS or KOOS preoperatively and 2 years postoperatively. Short-form joint replacement (JR) versions of each PROM were derived from the full PROMs. Of all eligible patients, 78% (3161 of 4080) of THAs and 74% of TKAs (3815 of 5156) consented to join the registry and completed a baseline survey, 88% (2796 of 3161) of THAs and 85% (3230 of 3815) of TKAs were eligible for followup survey administration, and 83% of THAs (2323 of 2796) and 81% (2630 of 3230) of TKAs returned 2-year surveys. For each HOOS domain, KOOS domain, HOOS, JR, and KOOS, JR, we calculated the calibration variation of the instrument (MDC) with confidence intervals (CIs) reflecting 80% (MDC80), 90% (MDC90), and 95% (MDC95) certainty; we calculated the smallest difference joint health patients might detect (MCID) using distribution- and anchor-based approaches and the difference that can be considered a large improvement in joint health (substantial clinical benefit) using an anchor-based approach.
Results: Patients undergoing THA were 57% female with a mean (± SD) age of 73 ± 6 years, whereas patients undergoing TKA were 63% female with a mean age of 74 ± 6 years. Depending on the CI chosen for the MDC, values ranged from 7 to 16 for the HOOS and KOOS domains and the JRs. The MCIDs ranged from 6 to 9 for the distribution-based approach and 7 to 36 for the anchor-based approach. All HOOS and KOOS domains and all JR scores are scores from 0 (worst joint health) to 100 (best joint health). The MCIDs calculated using the distribution-based approach were not valid, because they were lower than the MDC for all HOOS/KOOS domains and both JRs at every confidence level. The anchor-based receiver operating characteristic approach, on the other hand, resulted in MCIDs exceeding MDC80 for seven of eight HOOS/KOOS domains and MDC95 for both JR scores. For all domains and JR versions, substantial clinical benefits ranged from 15 to 36, exceeding MDC95 in all domains and JR scores. Across HOOS and KOOS domains as well as the JR, the proportion of patients undergoing THA who achieved an MCID ranged from 77% to 95% with the distribution-based method and from 67% to 96% using the anchor-based method. The proportion achieving substantial clinical benefit ranged from 67% to 85%.
Conclusions: The MDC and MCID differ greatly based on assumptions and methods used. The MCID anchor-based approach had superior construct and face validity compared with the MCID distribution-based approach, which never exceeded even small MDCs. Achieving consensus about standard definitions of meaningful improvement will be necessary to maximize utility of these PROMs to inform clinical care or performance measurement.

Defining distinct negative beliefs about uncertainty: validating the factor structure of the Intolerance of Uncertainty Scale.
This study examined the factor structure of the English version of the Intolerance of Uncertainty Scale (IUS; French version: M. H. Freeston, J. Rhéaume, H. Letarte, M. J. Dugas, & R. Ladouceur, 1994; English version: K. Buhr & M. J. Dugas, 2002) using a substantially larger sample than has been used in previous studies. Nonclinical undergraduate students and adults from the community (M age = 23.74 years, SD = 6.36; 73.0% female and 27.0% male) who participated in 16 studies in the Anxiety Disorders Laboratory at Concordia University in Montreal, Canada were randomly assigned to 2 datasets. Exploratory factor analysis with the 1st sample (n = 1,230) identified 2 factors: the beliefs that "uncertainty has negative behavioral and self-referent implications" and that "uncertainty is unfair and spoils everything." This 2-factor structure provided a good fit to the data (Bentler-Bonett normed fit index = .96, comparative fit index = .97, standardized root-mean residual = .05, root-mean-square error of approximation = .07) upon confirmatory factor analysis with the 2nd sample (n = 1,221). Both factors showed similarly high correlations with pathological worry, and Factor 1 showed stronger correlations with generalized anxiety disorder analogue status, trait anxiety, somatic anxiety, and depressive symptomatology.

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.

Spousal perceptions of marital stress and support among grandparent caregivers: variations by life stage.
Few studies have examined how raising grandchildren influences the marital relationship of grandparent caregivers although half of such caregivers are married. This study used national survey data from Midlife Development in the United States (MIDUS) to contrast perceptions of spousal support and strain for grandparents who had recently provided care for grandchildren along with their own young children (n=16), and grandparents who had recently cared for grandchildren only (n=96). Results revealed an interaction between caregivers' sex and family situation with grandmother caregivers who were raising both their own minor children and grandchildren reporting less spousal support than grandfathers in the same situation. Differences on the spousal strain dimension were not significant. Grandmother caregivers occupying 2 caregiving roles appear to have a unique experience with caring for grandchildren. These results parallel other studies that show that grandparent caregivers have poorer outcomes when they hold multiple caregiving roles simultaneously.

(2016)MEDLINE-indexed journal, not yet read by usJournal of psychopathology and behavioral assessment Development and Validation of a Brief Version of the Difficulties in Emotion Regulation Scale: The DERS-16.
The Difficulties in Emotion Regulation Scale (DERS) is a widely-used, theoretically-driven, and psychometrically-sound self-report measure of emotion regulation difficulties. However, at 36-items, the DERS may be challenging to administer in some situations or settings (e.g., in the course of patient care or large-scale epidemiological studies). Consequently, there is a need a briefer version of the DERS. The goal of the present studies was to develop and evaluate a 16-item version of the DERS - the DERS-16. The reliability and validity of the DERS-16 were examined in a clinical sample (N = 96) and two large community samples (Ns = 102 and 482). The validity of the DERS-16 was evaluated comparing the relative strength of the association of the two versions of the DERS with measures of emotion regulation and related constructs, psychopathology, and clinically-relevant behaviors theorized to stem from emotion regulation deficits. Results demonstrate that the DERS-16 has retained excellent internal consistency, good test-retest reliability, and good convergent and discriminant validity. Further, the DERS-16 showed minimal differences in its convergent and discriminant validity with relevant measures when compared to the original DERS. In conclusion, the DERS-16 offers a valid and brief method for the assessment of overall emotion regulation difficulties.

Anorexia nervosa: 30-year outcome.
Background: Little is known about the long-term outcome of anorexia nervosa.
Aims: To study the 30-year outcome of adolescent-onset anorexia nervosa.
Method: All 4291 individuals born in 1970 and attending eighth grade in 1985 in Gothenburg, Sweden were screened for anorexia nervosa. A total of 24 individuals (age cohort for anorexia nervosa) were pooled with 27 individuals with anorexia nervosa (identified through community screening) who were born in 1969 and 1971-1974. The 51 individuals with anorexia nervosa and 51 school- and gender-matched controls were followed prospectively and examined at mean ages of 16, 21, 24, 32 and 44. Psychiatric disorders, health-related quality of life and general outcome were assessed.
Results: At the 30-year follow-up 96% of participants agreed to participate. There was no mortality. Of the participants, 19% had an eating disorder diagnosis (6% anorexia nervosa, 2% binge-eating disorder, 11% other specified feeding or eating disorder); 38% had other psychiatric diagnoses; and 64% had full eating disorder symptom recovery, i.e. free of all eating disorder criteria for 6 consecutive months. During the elapsed 30 years, participants had an eating disorder for 10 years, on average, and 23% did not receive psychiatric treatment. Good outcome was predicted by later age at onset among individuals with adolescent-onset anorexia nervosa and premorbid perfectionism.
Conclusions: This long-term follow-up study reflects the course of adolescent-onset anorexia nervosa and has shown a favourable outcome regarding mortality and full symptom recovery. However, one in five had a chronic eating disorder.

Pathophysiology of the risk factors associated with osteoporosis and their correlation to the T-score value in patients with osteopenia and osteoporosis in the United Arab Emirates
INTRODUCTION Osteoporosis is a bone disorder, characterized by loss of bone strength because of an imbalance between the bone resorption and the mechanisms of bone formation, leading to increased fragility and fractures. Pathophysiological mechanisms underlying this disorder include an inadequate formation response during the remodeling process of bone formation, which is an essential factor in osteoporosis pathogenesis. This inadequacy is due to the activation of large numbers of osteoclasts as a response to initiation of hematopoietic precursor cells with failure of normal interaction with the osteoblastic lineage. This will lead to excessive bone resorption that may result in complete loss of trabecular structure and loss of template for new bone formation. The time required for osteoblastic replacement is longer than the resorption phase of bone remodeling by osteoclasts. Therefore, any increase in bone remodeling will lead to damaged architecture and loss of bone mass.[1] Recently, it has been estimated that more than 200 million people worldwide have osteoporosis. On the basis of a statistics from the International Osteoporosis Foundation in 2017, one in five men and one in three women over the age of 50 years will experience fractures during their lifetime because of osteoporosis. Furthermore, it has been found that an osteoporotic fracture occurs every 3s, with the most common fractures occurring at the hip, spine, and wrist.[23] Osteoporotic fractures may be the first manifestation of the disease, which is why it is called a silent disease. Risk factors of osteoporosis, decreased bone mineral density (BMD), and increased fragility fractures may be modifiable or non-modifiable. Among the modifiable factors are low body mass index (BMI), vitamin D deficiency, low calcium intake, excessive caffeine and alcohol consumption, smoking, sedentary life and low physical activity, endocrine disorders (such as estrogen deficiency and insulin-dependent diabetes mellitus or hyperparathyroidism), some drugs (such as corticosteroids), and previous history of fragility fractures. The non-modifiable factors include female gender, family history, race, and early menopause.[45] According to the World Health Organization (WHO) diagnostic criteria, osteoporosis is diagnosed by BMD at the hip or spine, which is below the young normal mean reference population by 2.5 standard deviations (SDs) or more. This is called the T-score, and osteopenia is diagnosed by BMD less than or equal to 1 SD.[6] The guidelines for osteoporosis screening vary greatly in various publications. In general, most organizations recommend that all adults older than 50 years of age with a history of fracture must receive BMD screening.[7] Dual-energy X-ray absorptiometry (DXA) at the hip or spine is the best test for measuring central BMD. An association is present between the T-score values in DXA in patients with osteoporosis or osteopenia and the risk of fractures. A fracture risk assessment tool (FRAX) was designed. It is estimated that for every 1 SD decline in spine BMD, the risk of having a spine fracture increases 2.3 times and the risk of having a hip fracture increases 2.6 times.[89] As the most common bone disease in humans, the prevalence of osteoporosis is steadily increasing due to a growing elderly population, and thus represents a major public health concern with reduced bone strength and a higher risk of fractures.[68] The prevalence of osteoporosis is steadily escalating due to increased life expectancy as a result of developed health services. According to the 2016 WHO report, in the United Arab Emirates (UAE), life expectancy at birth for men was 76 years and for women it was 79 years.[10] The UAE population projection showed that in 2011, 7% of the population were 50 years of age or over and less than 1% were 70 years of age or over. By 2050, it is estimated that 12% of the population will be 50 years or over and 2% will be 70 years or over.[11] MATERIALS AND METHODS Study design The study was performed in accordance with the International Conference on Harmonisation Good Clinical Practice guidelines. Ethical approval number UG-H-18-11-7-10 was obtained from the Research Ethics Committee of the college. The study was conducted on a population sample of national and nonnational people in the UAE. Both men and women were recruited in the study. Data were collected from the patients in six governmental and private hospitals. Research tools A total of 200 male and female participants between the age of 25 and 80 years were recruited in the study. Eighty percent of the sample were women and 20% were men. After obtaining the required consent, each participant was asked to fill a structured questionnaire consisting of 25 questions, which was used as the primary tool for data collection. The questions were formulated both in Arabic and English, it required 3–4min to be completed. BMD of the participants was assessed in the International Radiology Centre and correlated with their data in the questionnaires. DXA scan was used for the measurement of BMD. Data collection and data analysis After ensuring strict confidentiality, data were collected between March 20, 2016 and May 20, 2016. The following information was obtained: Demographic data (gender, age, race, BMI, and occupation) Family history of osteoporosis or osteoporotic fractures Social history and lifestyle, physical activity, and exposure to the sun Dietary habits such as calcium, caffeine, and soft drinks intake Medical history of diseases and medicines. For female participants, number of pregnancies, lactation, and age at menopause were included The following criteria were used to evaluate osteoporosis: Normal BMD: if T-score between +2.5 and –1 Osteopenia: if T-score between –1 and –2.5 Osteoporosis: if T-score below –2.5 The filled questionnaires were coded and data were analyzed statistically using the Statistical Package for the Social Sciences (SPSS) software (version 24; IBM Corporation, Newyork, USA). Spearman’s correlation test was carried out to assess the association between different variables in the study. A P value of less than 0.05 was considered significant. RESULTS Sociodemographic data The sociodemographic background of the study participants is listed in Table 1. A total of 200 participants were included in the study. The control group and the osteoporotic group consisted of 100 participants each, 20% of them were men, whereas 80% of the respondents were women. Table 1: Background demographic data of the respondentsBody mass index The patients with osteoporosis have significantly lower BMI than the control group (P < 0.05). Results showed that 72% of them have a BMI less than 25 kg/m2 (P < 0.05) [Table 2] [Figure 1].Table 2: Body mass index of the respondentsFigure 1: Body mass index (kg/m2) of the respondentsSmoking behavior Regarding smoking behavior, a significant value was evident between smoking and osteoporosis (P < 0.01) as 54% of the patients with osteoporosis were current smokers, whereas 72% of the controls had never smoked before [Table 3] [Figure 2].Table 3: Smoking behavior and intake of milk, coffee, and soft drinks by the respondentsFigure 2: Intake of milk and caffeine and smoking behavior by the respondentsDietary calcium intake The intake of milk and dairy products by the participants was used to assess the dietary calcium intake. The patients with osteoporosis have a significant low calcium intake (P < 0.01), whereas non-osteoporotic control significantly consume more milk and dairy products (P < 0.01). A positive correlation was found between the intake of milk and dairy products and the T-score value of the participants (P < 0.05) [Table 3] [Figures 2 and 3].Figure 3: Correlation between milk intake and T-score in patients with osteoporosisCaffeine consumption Caffeine intake was evaluated in this study by the amount of coffee, tea, or soft drinks consumed by the participants each day. The results showed that the patients with osteoporosis significantly consume more caffeine (P < 0.01). A negative correlation is present between the amount of caffeine intake and T-score value of the participants (P < 0.05) [Table 3] [Figures 2, 4, and 5].Figure 4: Correlation between tea/coffee intake and T-score in patients with osteoporosisFigure 5: Correlation between soft drinks intake and T-score in patients with osteoporosisExercise behavior and exposure to the sun Results showed a significant positive correlation between the duration of exercise and the T-score value of the participants (P < 0.05) [Table 4] [Figure 6].Table 4: Exercise behavior and exposure to sun of the respondentsFigure 6: Correlation between exercise duration and T-score in patients with osteoporosisRegarding the exposure to the sun, the results showed that 96% of the patients with osteoporosis were exposed to the sun for less than 15min, three to four times a week or not exposed at all, whereas most of the normal controls (72%) exposed their bodies to the sun for 16–30min/day, three to four times a week [Table 4] [Figure 7].Figure 7: Sun exposure behavior of the respondentsDiseases and medications Results of the study revealed that 46% of the patients with osteoporosis were diabetic, 42% of them were treated by antidiabetics, 18% had arthritis and 38% had been treated previously by corticosteroids [Table 5].Table 5: Distribution of patients with osteoporosis by their diseases and medicationsNumber of pregnancies and breastfeeding Female participants constituted 80% of the study sample, 75% of the females with osteoporosis were menopausal, 75% of them had three or more pregnancies, and 82.5% of them breastfed their children, whereas these values for the control group participants are 30%, 28%, and 33%, respectively. Results showed a significant positive correlation between the age at menopause and the T-score value of females with osteoporosis (P < 0.05) [Table 6] [Figure 8]. The distribution of patients according to the joint affected by Osteoporosis or Osteopenia is shown in [Figure 9] and [Table 7].Table 6: Distribution of female patients with osteoporosis by number of pregnancies and breastfeedingFigure 8: Correlation between age at menopause and T-score in female patients with osteoporosisFigure 9: Distribution of patients having osteopenia or osteoporosis in wrists, hips, or spineTable 7: Distribution of patients having osteoporosis and/or osteopenia in hips, wrists, and spineDISCUSSION To maintain normal bone structure, a remodeling process that consists of osteoclasts, removing old bone, and osteoblasts, synthesizing new bone, occurs. Hematopoietic progenitors produce osteoclasts, whereas mesenchymal stem cells called marrow stromal fibroblasts produce osteoblasts. This process is controlled by certain circulating hormones, growth factors, and locally produced cytokines through their effects on apoptosis of osteoblasts and osteoclasts. Estrogen deficiency or glucocorticoid excess leads to bone loss because of changes in the production of bone cells. This is caused by the prolongation of the life span of osteoclasts and the shortening of the life span of osteoblasts. On the contrary, drugs that aim to treat or prevent osteoporosis prevent apoptosis of osteoblasts and/or stimulate the apoptosis of osteoclasts.[12] The pathogenesis of osteoporosis is the consequence of various hormonal, genetic, dietary, lifestyle, and physical factors. Genetic factors mainly affect the BMD and bone formation, whereas low levels of estrogen increase parathyroid hormone, and local cytokines are mainly responsible for bone remodeling imbalance.[13] Age and gender In this study, 76% of the patients with osteoporosis were women at or above 50 years of age. Osteoporosis is usually considered a disease of the elderly with low BMD. In a recent study, most of the patients with osteoporosis were in the age groups of 45–49 and 50–54 years.[14] Previous studies showed that women were at an increased risk of developing osteoporosis because of their faulty behavior of physical inactivity, sun-avoidance behavior, low intake of dairy products, and poor diets.[151617] Body mass index The results of this study showed a significant number of patients of osteoporosis with BMI <25 kg/m2, where P < 0.05. Women that have low BMI are at a higher risk of developing osteoporosis. It is reported that one unit change in BMI has a larger effect on the risk of developing osteoporosis than most other modifiable risk factors. To help reduce the risk of osteoporosis, patients should be advised to maintain a weight within the normal range.[1516] The risk of osteoporotic fractures increases in adults who have low BMI of less than 20 kg/m2.[18] On the contrary, patients who are obese (BMI >30 kg/m2) are also at a high risk of developing osteoporosis and fractures because of the risk of repeated falls and the weakness of the skeletal muscles due to loss of its mass as a result of aging.[19] Exercise and physical activity The results of this study showed a significant correlation between the exercise time and the T-score value. Previous studies concluded that physical activity and exercises stimulate skeletal growth and bone strength.[45] Estrogen Estrogen deficiency has a critical effect on the pathogenesis of osteoporosis. The results of this study showed a significant positive correlation between the age at menopause and the T-score value of the female patients. Estrogen has a crucial role in bone formation and physiology. It stimulates the production of T cell cytokines, affects the osteoblastic cell by altering its production of receptor activator of nuclear factor-Kappa B ligand (RANKL) or Osteoprotegerin (OPG), inhibits the differentiation of osteoclasts by direct action, and stimulates the formation of bone performed by osteoblasts and osteocytes, which allows them to enhance their ability to respond to mechanical forces.[2021] Estrogen produces its effect through a specific cell surface receptor called the estrogen receptor alpha (ERα). This receptor binds and then transports estrogen into the nucleus of the cell where certain genes are then activated by the receptor–hormone complex. ERα receptors and estrogen receptor–related receptor alpha (ERRα) are found on the surface of osteoblasts. ERRα may play a supporting role in the regulation of bone cells.[22] Previous studies also suggest that sex hormone–binding globulin may play a significant role in regulating bone cells as well because it facilitates entry of estrogen into cells.[23] Because of the natural drop of estrogen level in postmenopausal women, they are at the highest risk of developing osteoporosis. A previous study showed that it is an increase in bone resorption that might be the driving force for bone loss during estrogen deficiency in postmenopausal women not impaired bone formation as was previously thought.[1] However, other studies indicated that both markers of bone resorption and formation also increased, leading to accelerated bone remodeling at menopause.[2425] Calcium intake and vitamin D Calcium and vitamin D are two pivotal contributors of bone formation and mineralization. The results of this study showed that the patients with osteoporosis have a significant low calcium intake, whereas controls significantly consume more milk and dairy products (P < 0.01). This significant result showed the importance of calcium intake. Results also established a positive correlation between calcium intake and the T-score value of the participants. Vitamin D plays an important role in maintaining calcium homeostasis and bone integrity as it is essential for intestinal calcium absorption.[26] It is estimated that over one billion people around the world have vitamin D deficiency.[2728] Sun exposure is considered as the source of vitamin D, the present results showed a significant value (P < 0.01) as 74% of the patients with osteoporosis exposed their bodies to the sun for 5min or less, three to four times per week, whereas 72% of controls exposed their bodies to the sun for 15–30min, 3 to 4 times a week. A previous study conducted in the UAE showed that 58.2% of the UAE nationals were vitamin D deficient compared to 45% of the patients from other nationalities.[29] In spite of living in sunny areas, such as UAE, Saudi Arabia, and India, young populations have a high prevalence of vitamin D deficiency because of insufficient knowledge and practice of vitamin D and its health implications.[3031] Decreased blood calcium level will lead to secondary hyperparathyroidism. This decrease may result from impaired intestinal calcium absorption due to vitamin D deficiency, aging, or other diseases. Calcitriol, the active form of vitamin D, stimulates the intestinal absorption of calcium and phosphorus. It has an inhibitory effect on the synthesis of parathyroid hormone as well. Therefore, calcitriol deficiency will lead to secondary hyperparathyroidism as well.[32] There is a clear evidence that the risk of having an osteoporotic fracture increases when vitamin D levels are below 50 nmol.[3334] However, a recent study showed that pathological macrophages produced by vitamin D receptor signaling play an important role in the development of myelofibrosis.[35] Smoking The results of this study showed that nicotine has a significant effect on the incidence of osteoporosis (P < 0.01). Smoking has been identified as a modifiable risk factor for low BMD and increased osteoporotic fracture risk.[3637] Smoking behavior should be evaluated when assessing the fracture risk and FRAX.[1638] The role of smoking in decreasing BMD is complicated; smoking is shown to be associated with other risk factors for osteoporosis such as decreased physical activity, low BMI, and poor diet.[38] Nicotine has both direct and indirect effects on BMD. The direct effect is on bone cell proliferation and is described to be biphasic, small doses have a stimulatory effect, whereas toxic large doses have an antiproliferative effect on the proliferation of osteoblasts.[39] This effect on osteoblasts is receptor mediated by the nicotinic acetylcholine receptors, where nicotine in low doses upregulates gene expression of alkaline phosphatase, type 1 collagen, and osteocalcin.[40] Nicotine produces an increased level of tumor necrosis factor α (TNFα) secretion that reduces bone formation by osteoblasts and increases bone resorption by osteoclasts. TNFα has a powerful osteoclastogenic effect through its stimulating effect on RANKL production and by intensifying osteoclasts production.[41] It is strongly supported that RANK/RANKL/OPG systems have a role in regulating bone resorption and the formation of osteoclasts.[42] The main predisposing factor for chronic obstructive pulmonary disease (COPD) has been found to be smoking. The most important factor in managing COPD continues to be the termination of smoking.[43] It has been shown in numerous studies that smokers with COPD have elevated levels of pro-inflammatory cytokines in the form of interleukin-6. In addition, TNFα levels are much higher in COPD smokers than in asymptomatic smokers. This indicates that COPD affects local and systemic inflammatory responses, which in turn affects bone remodeling.[4445] Nicotine has an indirect effect on BMD, which is caused by releasing calcitropic hormones and glucocorticoids, which leads to an increase in bone resorption.[43] Furthermore, smoking has been linked to an increase in the level of cortisol[4446] as well as a decrease in the level of estradiol.[47] Nicotine also harms intestinal calcium absorption, which might lessen the effectiveness of dietary calcium supplements.[48] Also, toxic carcinogenic metabolites of nicotine have also been found to increase osteoclast formation in rats.[49] Moreover, one hip fracture in eight postmenopausal women with osteoporosis is attributable to smoking. This correlation could not be explained by early menopause, low BMI, lower levels of exercise, or by the actions of nicotine on estrogen. This indicates that there is an independent negative effect of nicotine on BMD, which means that smokers lose bone at a faster rate than nonsmokers.[50] CONCLUSION Prevalence of osteoporosis is high in the UAE and is expected to grow due to increased life expectancy and faulty lifestyle of inadequate dietary habits, sun exposure, exercise behavior, and smoking. More intervention should be directed toward changing the modifiable risk factors in the patients with osteoporosis, and more studies should be directed toward osteoporosis in the UAE. Limitations of the study To make the study a polycentric research, it would require greater number of participants from all the emirates of the UAE.

Background: Young people whose parents have depression have a greatly increased risk of developing a psychiatric disorder, but poor outcomes are not inevitable. Identification of the contributors to mental health resilience in young people at high familial risk is an internationally recognised priority. Our objectives were to identify protective factors that predict sustained good mental health in adolescents with a parent with depression and to test whether these contribute beyond what is explained by parent illness severity.
Methods: The Early Prediction of Adolescent Depression study (EPAD) is a prospective longitudinal study of offspring of parents with recurrent depression. Parents with recurrent major depressive disorder, co-parents, and offspring (aged 9-17 years at baseline) were assessed three times over 4 years in a community setting. Offspring outcomes were operationalised as absence of mental health disorder, subthreshold symptoms, or suicidality on all three study occasions (sustained good mental health); and better than expected mental health (mood and behavioural symptoms at follow-up lower than predicted given severity of parental depression). Family, social, cognitive, and health behaviour predictor variables were assessed using interview and questionnaire measures.
Findings: Between February and June, 2007, we screened 337 families at baseline, of which 331 were eligible. Of these, 262 completed the three assessments and were included in the data for sustained mental health. Adolescent mental health problems were common, but 53 (20%) of the 262 adolescents showed sustained good mental health. Index parent positive expressed emotion (odds ratio 1·91 [95% CI 1·31-2·79]; p=0·001), co-parent support (1·90 [1·38-2·62]; p<0·0001), good-quality social relationships (2·07 [1·35-3·18]; p=0·001), self-efficacy (1·49 [1·05-2·11]; p=0·03), and frequent exercise (2·96 [1·26-6·92]; p=0·01) were associated with sustained good mental health. Analyses accounting for parent depression severity were consistent, but frequent exercise only predicted better than expected mood-related mental health (β=-0·22; p=0·0004) not behavioural mental health, whereas index parents' expression of positive emotions predicted better than expected behavioural mental health (β=-0·16; p=0·01) not mood-related mental health. Multiple protective factors were required for offspring to be free of mental health problems (zero or one protective factor, 4% sustained good mental health; two protective factors, 10%; three protective factors, 13%, four protective factors, 38%; five protective factors, 48%).
Interpretation: Adolescent mental health problems are common, but not inevitable, even when parental depression is severe and recurrent. These findings suggest that prevention programmes will need to enhance multiple protective factors across different domains of functioning.

Smartphone Time Machine: Tech-Supported Improvements in Time Perspective and Wellbeing Measures.
Individuals with a balanced time perspective, which includes good thoughts about the past, awareness of present constraints and adaptive planning for a positive future, are more likely to report optimal wellbeing. However, people who have had traumas such as adverse childhood experiences (ACEs) are likely to have less balanced time perspectives and lower overall wellbeing when compared to those with fewer or no ACEs. Time perspective can be improved via time-travel narratives that support people in feeling connected to a wise and loving future version of themselves, an approach that has until now only been provided in counseling contexts. Our team used an iterative inclusive design process to shape a scalable time-travel narrative tool - a responsive and progressive web application called Time Machine. Among other functionalities, Time Machine allowed people to record and listen to messages as if they were from and to their past and future selves. Using pre-planned as well as post-hoc analyses, we analyzed quantitative and qualitative data from 96 paid design partners (participants) who were taken through a 26-day pilot study of the technology. Among other effects, the results revealed: (1) high engagement throughout the design process, (2) improvements in self-reported time perspective and overall wellbeing scores that were greater for those using Time Machine during an optional-use period, (3) twice as much improvement in overall wellbeing scores for design partners with high ACEs (16%) versus low ACEs (8%), and (4) feelings of unconditional love apparently mediating the relationship between scores on time perspective and overall wellbeing measures. We discuss the limitations of these results as well as implications for the future role of spiritually informed scalable time-travel narrative technologies in healthcare and wellness.

Global, regional, and national burden of stroke and its risk factors, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019.
Background: Regularly updated data on stroke and its pathological types, including data on their incidence, prevalence, mortality, disability, risk factors, and epidemiological trends, are important for evidence-based stroke care planning and resource allocation. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) aims to provide a standardised and comprehensive measurement of these metrics at global, regional, and national levels.
Methods: We applied GBD 2019 analytical tools to calculate stroke incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and the population attributable fraction (PAF) of DALYs (with corresponding 95% uncertainty intervals [UIs]) associated with 19 risk factors, for 204 countries and territories from 1990 to 2019. These estimates were provided for ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage, and all strokes combined, and stratified by sex, age group, and World Bank country income level.
Findings: In 2019, there were 12·2 million (95% UI 11·0-13·6) incident cases of stroke, 101 million (93·2-111) prevalent cases of stroke, 143 million (133-153) DALYs due to stroke, and 6·55 million (6·00-7·02) deaths from stroke. Globally, stroke remained the second-leading cause of death (11·6% [10·8-12·2] of total deaths) and the third-leading cause of death and disability combined (5·7% [5·1-6·2] of total DALYs) in 2019. From 1990 to 2019, the absolute number of incident strokes increased by 70·0% (67·0-73·0), prevalent strokes increased by 85·0% (83·0-88·0), deaths from stroke increased by 43·0% (31·0-55·0), and DALYs due to stroke increased by 32·0% (22·0-42·0). During the same period, age-standardised rates of stroke incidence decreased by 17·0% (15·0-18·0), mortality decreased by 36·0% (31·0-42·0), prevalence decreased by 6·0% (5·0-7·0), and DALYs decreased by 36·0% (31·0-42·0). However, among people younger than 70 years, prevalence rates increased by 22·0% (21·0-24·0) and incidence rates increased by 15·0% (12·0-18·0). In 2019, the age-standardised stroke-related mortality rate was 3·6 (3·5-3·8) times higher in the World Bank low-income group than in the World Bank high-income group, and the age-standardised stroke-related DALY rate was 3·7 (3·5-3·9) times higher in the low-income group than the high-income group. Ischaemic stroke constituted 62·4% of all incident strokes in 2019 (7·63 million [6·57-8·96]), while intracerebral haemorrhage constituted 27·9% (3·41 million [2·97-3·91]) and subarachnoid haemorrhage constituted 9·7% (1·18 million [1·01-1·39]). In 2019, the five leading risk factors for stroke were high systolic blood pressure (contributing to 79·6 million [67·7-90·8] DALYs or 55·5% [48·2-62·0] of total stroke DALYs), high body-mass index (34·9 million [22·3-48·6] DALYs or 24·3% [15·7-33·2]), high fasting plasma glucose (28·9 million [19·8-41·5] DALYs or 20·2% [13·8-29·1]), ambient particulate matter pollution (28·7 million [23·4-33·4] DALYs or 20·1% [16·6-23·0]), and smoking (25·3 million [22·6-28·2] DALYs or 17·6% [16·4-19·0]).
Interpretation: The annual number of strokes and deaths due to stroke increased substantially from 1990 to 2019, despite substantial reductions in age-standardised rates, particularly among people older than 70 years. The highest age-standardised stroke-related mortality and DALY rates were in the World Bank low-income group. The fastest-growing risk factor for stroke between 1990 and 2019 was high body-mass index. Without urgent implementation of effective primary prevention strategies, the stroke burden will probably continue to grow across the world, particularly in low-income countries.

(2021)MEDLINE-indexed journal, not yet read by usJMIR mental health Mental Health Specialist Video Consultations Versus Treatment-as-Usual for Patients With Depression or Anxiety Disorders in Primary Care: Randomized Controlled Feasibility Trial.
Background: Most people affected by depression or anxiety disorders are treated solely by their primary care physician. Access to specialized mental health care is impeded by patients' comorbidity and immobility in aging societies and long waiting times at the providers' end. Video-based integrated care models may leverage limited resources more efficiently and provide timely specialized care in primary care settings.
Objective: The study aims to evaluate the feasibility of mental health specialist video consultations with primary care patients with depression or anxiety disorders.
Methods: Participants were recruited by their primary care physicians during regular practice visits. Patients who had experienced at least moderate symptoms of depression and/or anxiety disorders were considered eligible for the study. Patients were randomized into 2 groups receiving either treatment-as-usual as provided by their general practitioner or up to 5 video consultations conducted by a mental health specialist. Video consultations focused on systematic diagnosis and proactive monitoring using validated clinical rating scales, the establishment of an effective working alliance, and a stepped-care algorithm within integrated care adjusting treatments based on clinical outcomes. Feasibility outcomes were recruitment, rate of loss to follow-up, acceptability of treatment, and attendance at sessions. Effectiveness outcomes included depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), burden of specific somatic complaints (Somatic Symptom Disorder-B Criteria Scale-12), recovery (Recovery Assessment Scale-German [RAS-G]), and perception of chronic illness care (Patient Assessment of Chronic Illness Care), which were measured at baseline and 16 weeks postallocation by assessors blinded to the group allocation.
Results: A total of 50 patients with depression and/or anxiety disorders were randomized, 23 in the intervention group and 27 in the treatment-as-usual group. The recruitment yield (number randomized per number screened) and the consent rate (number randomized per number eligible) were 69% (50/73) and 86% (50/58), respectively. Regarding acceptability, 87% (20/23) of the participants in the intervention group completed the intervention. Of the 108 planned video consultations, 102 (94.4%) were delivered. Follow-up rates were 96% (22/23) and 85% (23/27) for the intervention and control groups, respectively. The change from baseline scores at postmeasurement for the No Domination by Symptoms domain of recovery (RAS-G) was somewhat higher in the intervention group than in the control group (Mann-Whitney U test: rank-biserial r=0.19; 95% CI -0.09 to 0.46; P=.18). We did not detect any notable differences between the intervention and control groups in terms of other effectiveness outcomes. We did not observe any serious adverse events related to the trial.
Conclusions: The intervention and study procedures were found to be feasible for patients, primary care practice staff, and mental health specialists. A sufficiently powered pragmatic trial on mental health specialist video consultations should be conducted to investigate their effectiveness in routine care.

(2018)MEDLINE-indexed journal, not yet read by usJAMA network open Coverage of Nonpharmacologic Treatments for Low Back Pain Among US Public and Private Insurers.
Importance: Despite epidemic rates of addiction and death from prescription opioids in the United States, suggesting the importance of providing alternatives to opioids in the treatment of pain, little is known regarding how payers' coverage policies may facilitate or impede access to such treatments.
Objective: To examine coverage policies for 5 nonpharmacologic approaches commonly used to treat acute or chronic low back pain among commercial and Medicare Advantage insurance plans, plus an additional 6 treatments among Medicaid plans.
Design, setting, and participants: Cross-sectional study of 15 commercial, 15 Medicaid, and 15 Medicare Advantage health plans for the 2017 calendar year in 16 states representing more than half of the US population. Interviews were conducted with 43 senior medical and pharmacy health plan executives from representative plans.
Main outcomes and measures: Medical necessity and coverage status for the treatments examined, as well as the use of utilization management tools and cost-sharing magnitude and structure.
Results: Commercial and Medicare insurers consistently regarded physical and occupational therapy as medically necessary, but policies varied for other therapies examined. Payers most commonly covered physical therapy (98% [44 of 45 plans]), occupational therapy (96% [43 of 45 plans]), and chiropractic care (89% [40 of 45 plans]), while transcutaneous electrical nerve stimulation (67% [10 of 15 plans]) and steroid injections (60% [9 of 15 plans]) were the most commonly covered among the therapies examined for Medicaid plans only. Despite evidence in the literature to support use of acupuncture and psychological interventions, these therapies were either not covered by plans examined (67% of all plans [30 of 45] did not cover acupuncture) or lacked information about coverage (80% of Medicaid plans [12 of 15] lacked information about coverage of psychological interventions). Utilization management tools, such as prior authorization, were common, but criteria varied greatly with respect to which conditions and what quantity and duration of services were covered. Interviewees represented 6 Medicaid managed care organizations, 2 Medicare Advantage or Part D plans, 9 commercial plans, and 3 trade organizations (eg, Blue Cross Blue Shield Association). Interviews with plan executives indicated a low level of integration between the coverage decision-making processes for pharmacologic and nonpharmacologic therapies for chronic pain.
Conclusions and relevance: Wide variation in coverage of nonpharmacologic treatments for low back pain may be driven by the absence of best practices, the administrative complexities of developing and revising coverage policies, and payers' economic incentives. Such variation suggests an important opportunity to improve the accessibility of services, reduce opioid use, and ultimately improve the quality of care for individuals with chronic, noncancer pain while alleviating the burden of opioid addiction and overdose.

Child & adolescent health 6-month multidisciplinary follow-up and outcomes of patients with paediatric inflammatory multisystem syndrome (PIMS-TS) at a UK tertiary paediatric hospital: a retrospective cohort study.
Background: Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) is a new, rare, post-infectious complication of SARS-CoV-2 infection in children. We aimed to describe the 6-month outcomes of PIMS-TS.
Methods: This retrospective cohort study comprised children (aged <18 years) who fulfilled the UK Royal College of Paediatrics and Child Health (RCPCH) diagnostic criteria for PIMS-TS and were admitted to Great Ormond Street Hospital (London, UK) between April 4 and Sept 1, 2020. Patients were followed up by a multidisciplinary team of specialists at 6 weeks and 6 months after admission. Biochemical and functional outcomes were analysed.
Findings: 46 children were included in this study. The median age at presentation was 10·2 years (IQR 8·8-13·3), 30 (65%) patients were male and 16 (35%) were female, 37 (80%) were from minority ethnic groups, and eight (17%) had pre-existing comorbidities. All patients had elevated markers of systemic inflammation at baseline. None of the patients died. By 6 months, systemic inflammation was resolved in all but one patient. 38 (90%) of 42 patients who had positive SARS-CoV-2 IgG antibodies within 6 weeks of admission remained seropositive at 6 months. Echocardiograms were normal in 44 (96%) of 46 patients by 6 months, and gastrointestinal symptoms that were reported in 45 (98%) of 46 patients at onset were present in six (13%) of 46 patients at 6 months. Renal, haematological, and otolaryngological findings largely resolved by 6 months. Although minor abnormalities were identified on neurological examination in 24 (52%) of 46 patients at 6 weeks and in 18 (39%) of 46 at 6 months, we found minimal functional impairment at 6 months (median Expanded Disability Status Scale score 0 [IQR 0-1]). Median manual muscle test-8 scores improved from 53 (IQR 43-64) during hospital admission to 80 (IQR 68-80) at 6 months, but 18 (45%) of 40 patients showed 6-min walk test results below the third centile for their age or sex at 6 months. PedsQL responses revealed severe emotional difficulties at 6 months (seven [18%] of 38 by parental report and eight [22%] of 38 by self report). 45 (98%) of 46 patients were back in full-time education (virtually or face to face) by 6 months.
Interpretation: Despite initial severe illness, few organ-specific sequelae were observed at 6 months. Ongoing concerns requiring physical re-conditioning and mental health support remained, and physiotherapy assessments revealed persisting poor exercise tolerance. Longer-term follow-up will help define the extended natural history of PIMS-TS.

Predictors of diaphragm use as a potential sexually transmitted disease/HIV prevention method in Zimbabwe.
Background: Women who are the most vulnerable to sexually transmitted diseases/HIV are often unable to consistently use condoms. One potential alternative method currently under investigation is the diaphragm.
Goals: The goals of this study were to assess diaphragm uptake and use over time in Zimbabwe and to identify factors associated with self-reported consistent diaphragm use.
Study: Women attending family planning clinics who were inconsistent condom users received a diaphragm intervention and were followed for 6 months.
Results: Of the 186 participants, 99% ever reported using the diaphragm, and, at study exit, 96% had used it in the previous 2 months. Consistent diaphragm use since the previous visit was reported by 13% to 16% of the women, and in multivariate regression analysis, it was significantly associated with never using condoms (adjusted odds ratio, 24.08; 95% confidence interval, 6.71-86.34). Other factors included discreet use, preferring diaphragms to condoms, timing of insertion, domestic violence, and contraception.
Conclusion: Diaphragms were well accepted among women at risk for sexually transmitted diseases/HIV.
