Video calls for reducing social isolation and loneliness in older people: a rapid review.

Background: The current COVID-19 pandemic has been identified as a possible trigger for increases in loneliness and social isolation among older people due to the restrictions on movement that many countries have put in place. Loneliness and social isolation are consistently identified as risk factors for poor mental and physical health in older people. Video calls may help older people stay connected during the current crisis by widening the participant's social circle or by increasing the frequency of contact with existing acquaintances. Objectives: The primary objective of this rapid review is to assess the effectiveness of video calls for reducing social isolation and loneliness in older adults. The review also sought to address the effectiveness of video calls on reducing symptoms of depression and improving quality of life. Search methods: We searched CENTRAL, MEDLINE, PsycINFO and CINAHL from 1 January 2004 to 7 April 2020. We also searched the references of relevant systematic reviews. Selection criteria: Randomised controlled trials (RCTs) and quasi-RCTs (including cluster designs) were eligible for inclusion. We excluded all other study designs. The samples in included studies needed to have a mean age of at least 65 years. We included studies that included participants whether or not they were experiencing symptoms of loneliness or social isolation at baseline. Any intervention in which a core component involved the use of the internet to facilitate video calls or video conferencing through computers, smartphones or tablets with the intention of reducing loneliness or social isolation, or both, in older adults was eligible for inclusion. We included studies in the review if they reported self-report measures of loneliness, social isolation, symptoms of depression or quality of life.  Two review authors screened 25% of abstracts; a third review author resolved conflicts. A single review author screened the remaining abstracts. The second review author screened all excluded abstracts and we resolved conflicts by consensus or by involving a third review author. We followed the same process for full-text articles. Data collection and analysis: One review author extracted data, which another review author checked. The primary outcomes were loneliness and social isolation and the secondary outcomes were symptoms of depression and quality of life. One review author rated the certainty of evidence for the primary outcomes according to the GRADE approach and another review author checked the ratings. We conducted fixed-effect meta-analyses for the primary outcome, loneliness, and the secondary outcome, symptoms of depression. Main results: We identified three cluster quasi-randomised trials, which together included 201 participants. The included studies compared video call interventions to usual care in nursing homes. None of these studies were conducted during the COVID-19 pandemic.  Each study measured loneliness using the UCLA Loneliness Scale. Total scores range from 20 (least lonely) to 80 (most lonely). The evidence was very uncertain and suggests that video calls may result in little to no difference in scores on the UCLA Loneliness Scale compared to usual care at three months (mean difference (MD) -0.44, 95% confidence interval (CI) -3.28 to 2.41; 3 studies; 201 participants), at six months (MD -0.34, 95% CI -3.41 to 2.72; 2 studies; 152 participants) and at 12 months (MD -2.40, 95% CI -7.20 to 2.40; 1 study; 90 participants). We downgraded the certainty of this evidence by three levels for study limitations, imprecision and indirectness. None of the included studies reported social isolation as an outcome. Each study measured symptoms of depression using the Geriatric Depression Scale. Total scores range from 0 (better) to 30 (worse). The evidence was very uncertain and suggests that video calls may result in little to no difference in scores on the Geriatric Depression Scale compared to usual care at three months' follow-up (MD 0.41, 95% CI -0.90 to 1.72; 3 studies; 201 participants) or six months' follow-up (MD -0.83, 95% CI -2.43 to 0.76; 2 studies, 152 participants). The evidence suggests that video calls may have a small effect on symptoms of depression at one-year follow-up, though this finding is imprecise (MD -2.04, 95% CI -3.98 to -0.10; 1 study; 90 participants). We downgraded the certainty of this evidence by three levels for study limitations, imprecision and indirectness. Only one study, with 62 participants, reported quality of life. The study measured quality of life using a Taiwanese adaptation of the Short-Form 36-question health survey (SF-36), which consists of eight subscales that measure different aspects of quality of life: physical function; physical role; emotional role; social function; pain: vitality; mental health; and physical health. Each subscale is scored from 0 (poor health) to 100 (good health). The evidence is very uncertain and suggests that there may be little to no difference between people allocated to usual care and those allocated to video calls in three-month scores in physical function (MD 2.88, 95% CI -5.01 to 10.77), physical role (MD -7.66, 95% CI -24.08 to 8.76), emotional role (MD -7.18, 95% CI -16.23 to 1.87), social function (MD 2.77, 95% CI -8.87 to 14.41), pain scores (MD -3.25, 95% CI -15.11 to 8.61), vitality scores (MD -3.60, 95% CI -9.01 to 1.81), mental health (MD 9.19, 95% CI 0.36 to 18.02) and physical health (MD 5.16, 95% CI -2.48 to 12.80). We downgraded the certainty of this evidence by three levels for study limitations, imprecision and indirectness. Authors' conclusions: Based on this review there is currently very uncertain evidence on the effectiveness of video call interventions to reduce loneliness in older adults. The review did not include any studies that reported evidence of the effectiveness of video call interventions to address social isolation in older adults. The evidence regarding the effectiveness of video calls for outcomes of symptoms of depression was very uncertain. Future research in this area needs to use more rigorous methods and more diverse and representative participants. Specifically, future studies should target older adults, who are demonstrably lonely or socially isolated, or both, across a range of settings to determine whether video call interventions are effective in a population in which these outcomes are in need of improvement.

Interventions for fatigue in people with kidney failure requiring dialysis.

Background: Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD). Objectives: We aimed to evaluate the effects of pharmacological and non-pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment. Search methods: We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov. Selection criteria: Studies evaluating pharmacological and non-pharmacological interventions affecting levels of fatigue or fatigue-related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue-related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered. Data collection and analysis: Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Main results: Ninety-four studies involving 8191 randomised participants were eligible. Pharmacological and non-pharmacological interventions were compared either to placebo or control, or to another pharmacological or non-pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high. In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis-Related Fatigue scale score): SMD -1.18, 95% CI -2.04 to -0.31; I2 = 87%) in HD. In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD -1.23, 95% CI -1.96 to -0.50; I2 = 93%) in HD. In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD -1.06, 95% CI -1.47, -0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD. In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD -0.64, 95% CI -1.03 to -0.25; I2 = 75%) in HD. A wide range of heterogenous interventions and fatigue-related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data. Due to the paucity of studies, the effects of pharmacological and other non-pharmacological interventions on fatigue or fatigue-related outcomes, including non-physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive-behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta-blockers, anabolic steroids, glucose-enriched dialysate, or light therapy, were very uncertain. The effects of pharmacological and non-pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported. Authors' conclusions: Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non-pharmacological interventions had uncertain effects on fatigue or fatigue-related outcomes in people receiving dialysis. Future adequately powered, high-quality studies are likely to change the estimated effects of interventions for fatigue and fatigue-related outcomes in people receiving dialysis.

Omega-3 fatty acids in the prevention of interferon-alpha-induced depression: results from a randomized, controlled trial.

Background: Interferon (IFN)-α therapy for chronic hepatitis C virus infection is frequently associated with depression. The routine prophylaxis with antidepressants might expose patients to adverse effects, hence, the need for alternative preventive interventions. Omega-3 polyunsaturated fatty acids are safe and effective essential nutritional compounds used for the treatment of depression, putatively through an anti-inflammatory action. In addition, lower erythrocyte levels of omega-3 polyunsaturated fatty acids have been associated with an increased risk of IFN-induced depression. Methods: We conducted a 2-week, double-blind, placebo-controlled trial comparing eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and placebo for the prevention of IFN-α-induced depression. A total of 162 patients consented to participate and were randomized to the study. All of the patients completed the 2-week trial; 152 participants were followed throughout the 24 weeks of IFN-α treatment and were included in the analysis. Results: Compared with placebo, the incident rates of IFN-α-induced depression were significantly lower in EPA-treated but not in DHA-treated patients (10% and 28%, respectively, versus 30% for placebo, p = .037). Both EPA and DHA significantly delayed the onset of IFN-induced depression (week of onset: 12.0 and 11.7, respectively, versus 5.3 for placebo, p = .002). EPA and DHA were both well tolerated in this population. EPA treatment increased both EPA and DHA erythrocyte levels, but DHA only increased DHA erythrocyte levels. Conclusions: EPA is effective in the prevention of depression in hepatitis C virus patients received IFN-α therapy. Our study confirms the notion that anti-inflammatory strategies are effective antidepressants in the context of depression associated with inflammation.

Effect of an Internet-Delivered Stepped-Care Program vs In-Person Cognitive Behavioral Therapy on Obsessive-Compulsive Disorder Symptoms in Children and Adolescents: A Randomized Clinical Trial.

Importance: In most countries, young people with obsessive-compulsive disorder have limited access to specialist cognitive behavioral therapy (CBT), a first-line treatment. Objective: To investigate whether internet-delivered CBT implemented in a stepped-care model is noninferior to in-person CBT for pediatric obsessive-compulsive disorder. Design, setting and participants: A randomized clinical noninferiority trial conducted at 2 specialist child and adolescent mental health clinics in Sweden. Participants included 152 individuals aged 8 to 17 years with obsessive-compulsive disorder. Enrollment began in October 2017 and ended in May 2019. Follow-up ended in April 2020. Interventions: Participants randomized to the stepped-care group (n = 74) received internet-delivered CBT for 16 weeks. Nonresponders at the 3-month follow-up were then offered a course of traditional face-to-face treatment. Participants randomized to the control group (n = 78) immediately received in-person CBT for 16 weeks. Nonresponders at the 3-month follow-up received additional face-to-face treatment. Main outcomes and measures: The primary outcome was the masked assessor-rated Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) score at the 6-month follow-up. The scale includes 10 items rated from 0 (no symptoms) to 4 (extreme symptoms), yielding a total score range of 0 to 40, with higher scores indicating greater severity. Assessors were masked to treatment allocation at pretreatment, posttreatment, 3-month follow-up, and 6-month follow-up assessments. The predefined noninferiority margin was 4 points on the CY-BOCS. Results: Among the 152 randomized participants (mean age, 13.4 years; 94 [62%] females), 151 (99%) completed the trial. At the 3-month follow-up, 34 participants (46%) in the stepped-care group and 23 (30%) in the in-person CBT group were nonresponders. At the 6-month follow-up, the CY-BOCS score was 11.57 points in the stepped-care group vs 10.57 points in the face-to-face treatment group, corresponding to an estimated mean difference of 0.91 points ([1-sided 97.5% CI, -∞ to 3.28]; P for noninferiority = .02). Increased anxiety (30%-36%) and depressive symptoms (20%-28%) were the most frequently reported adverse events in both groups. There were 2 unrelated serious adverse events (1 in each group). Conclusions and relevance: Among children and adolescents with obsessive-compulsive disorder, treatment with an internet-delivered CBT program followed by in-person CBT if necessary compared with in-person CBT alone resulted in a noninferior difference in symptoms at the 6-month follow-up. Further research is needed to understand the durability and generalizability of these findings. Trial registration: ClinicalTrials.gov Identifier: NCT03263546.

Nightmares and nonsuicidal self-injury: The mediating role of emotional dysregulation.

Introduction: Nonsuicidal self-injury (NSSI) is a transdiagnostic behavior associated with significant psychopathology. Research has shown a positive association between sleep disturbances, (e.g., nightmares and insomnia), and suicidal behavior, however, the relation between NSSI and sleep disturbances has yet to be examined. Sleep disturbances have been found to have a causal role in problems with emotional dysfunction. Specifically, sleep disturbances inhibit the emotion processing function of sleep. Importantly, a majority of individuals engage in NSSI to regulate intense emotions, and it is possible that sleep disturbances increase propensity for NSSI by contributing to dysregulated emotions. Methods: In two cross-sectional studies, the present research examined whether insomnia symptoms and nightmares were related to NSSI in a clinical sample (Study 1, N = 313) and in a university sample (Study 2, N = 152). Furthermore, the hypothesis that emotional dysregulation would atemporally mediate the relationship between sleep disturbances and NSSI was tested in Study 2. Results: Findings showed that nightmares, but not insomnia symptoms, were associated with NSSI while controlling for depressive symptoms. This pattern of findings was consistent across both clinical and university samples, which underscores the robustness of the finding. Further, the relationship between nightmares and NSSI was fully mediated by emotional dysregulation. Conclusion: The present research provides initial evidence that nightmares are atemporally associated with an increased propensity for NSSI by contributing to emotional dysregulation, and provides support for the emotion regulation function of dreams.

Victims Become Covert Aggressors: Gender Differences in the Mediating Effects of Rumination on Anger and Sadness.

This longitudinal study examined the link between peer victimization and relational aggression by testing the mediating roles of sadness and anger rumination, with attention to gender differences, among Chinese adolescents. Survey measures were administrated to 2,152 junior middle school students at two time points, one year apart. The results found that self-reported peer victimization (but not peer-nominated victimization) positively predicted relational aggression one year later, and this link was completely mediated by sadness and anger rumination. Specifically, perceived peer victimization exerted a positive influence on both sadness and anger rumination, thereby increasing adolescents' tendency to exhibit relational aggression one year later. Furthermore, victimized boys' elevated relational aggression was predominantly accounted for by their high sadness rumination, whereas victimized girls' elevated relational aggression was mainly due to their great anger rumination. Such a gender-difference suggests that interventions to reduce adolescents' externalizing problems may be most effective when tailored to each gender specifically.

Exercise as Medicine for Mental and Substance Use Disorders: A Meta-review of the Benefits for Neuropsychiatric and Cognitive Outcomes.

Background: Exercise may improve neuropsychiatric and cognitive symptoms in people with mental disorders, but the totality of the evidence is unclear. We conducted a meta-review of exercise in (1) serious mental illness (schizophrenia spectrum, bipolar disorder and major depression (MDD)); (2) anxiety and stress disorders; (3) alcohol and substance use disorders; (4) eating disorders (anorexia nervosa bulimia nervosa, binge eating disorders, and (5) other mental disorders (including ADHD, pre/post-natal depression). Methods: Systematic searches of major databases from inception until 1/10/2018 were undertaken to identify meta-analyses of randomised controlled trials (RCTs) of exercise in people with clinically diagnosed mental disorders. In the absence of available meta-analyses for a mental disorder, we identified systematic reviews of exercise interventions in people with elevated mental health symptoms that included non-RCTs. Meta-analysis quality was assessed with the AMSTAR/+. Results: Overall, we identified 27 systematic reviews (including 16 meta-analyses representing 152 RCTs). Among those with MDD, we found consistent evidence (meta-analyses = 8) that exercise reduced depression in children, adults and older adults. Evidence also indicates that exercise was more effective than control conditions in reducing anxiety symptoms (meta-analyses = 3), and as an adjunctive treatment for reducing positive and negative symptoms of schizophrenia (meta-analyses = 2). Regarding neurocognitive effects, exercise improved global cognition in schizophrenia (meta-analyses = 1), children with ADHD (meta-analyses = 1), but not in MDD (meta-analyses = 1). Among those with elevated symptoms, positive mental health benefits were observed for exercise in people with pre/post-natal depression, anorexia nervosa/bulimia nervosa, binge eating disorder, post-traumatic stress disorder and alcohol use disorders/substance use disorders. Adverse events were sparsely reported. Conclusion: Our panoramic meta-overview suggests that exercise can be an effective adjunctive treatment for improving symptoms across a broad range of mental disorders.

Efficacy of school-based interventions aimed at decreasing sugar-sweetened beverage consumption among adolescents: a systematic review.

Objective: To verify the efficacy of school-based interventions aimed at reducing sugar-sweetened beverage (SSB) consumption among adolescents in order to develop or improve public health interventions. Design: Systematic review of interventions targeting adolescents and/or the school environment. Setting: The following databases were investigated: MEDLINE/PubMed, PsycINFO, CINAHL and EMBASE. Proquest Dissertations and Theses was also investigated for unpublished trials. Subjects: Adolescents were defined as individuals between the ages of 12 and 17 years. Results: A total of thirty-six studies detailing thirty-six different interventions tested among independent samples (n 152 001) were included in the review. Twenty interventions were classified as educational/behavioural and ten were classified as legislative/environmental interventions. Only six interventions targeted both individuals and their environment. Over 70 % of all interventions, regardless of whether they targeted individuals, their environment or both, were effective in decreasing SSB consumption. Legislative/environmental studies had the highest success rate (90·0 %). Educational/behavioural interventions only and interventions that combined educational/behavioural and legislative/environmental approaches were almost equally effective in reducing SSB consumption with success rates of 65·0 and 66·7 %, respectively. Among the interventions that had an educational/behavioural component, 61·5 % were theory-based. The behaviour change techniques most frequently used in interventions were providing information about the health consequences of performing the behaviour (72·2 %), restructuring the physical environment (47·2 %), behavioural goal setting (36·1 %), self-monitoring of behaviour (33·3 %), threat to health (30·6 %) and providing general social support (30·6 %). Conclusions: School-based interventions show promising results to reduce SSB consumption among adolescents. A number of recommendations are made to improve future studies.

Cost-effectiveness and economic returns of group-based parenting interventions to promote early childhood development: Results from a randomized controlled trial in rural Kenya.

Background: Early childhood development (ECD) programs can help address disadvantages for the 43% of children under 5 in low- and middle-income countries (LMICs) experiencing compromised development. However, very few studies from LMIC settings include information on their program's cost-effectiveness or potential returns to investment. We estimated the cost-effectiveness, benefit-cost ratios (BCRs), and returns on investment (ROIs) for 2 effective group-based delivery models of an ECD parenting intervention that utilized Kenya's network of local community health volunteers (CHVs). Methods and findings: Between October 1 and November 12, 2018, 1,152 mothers with children aged 6 to 24 months were surveyed from 60 villages in rural western Kenya. After baseline, villages were randomly assigned to one of 3 intervention arms: a group-only delivery model with 16 fortnightly sessions, a mixed-delivery model combining 12 group sessions with 4 home visits, and a control group. At endline (August 5 to October 31, 2019), 1,070 children were retained and assessed for primary outcomes including cognitive and receptive language development (with the Bayley Scales of Infant Development, Third Edition) and socioemotional development (with the Wolke scale). Children in the 2 intervention arms showed better developmental outcomes than children in the control arm, although the group-only delivery model generally had larger effects on children. Total program costs included provider's implementation costs collected during the intervention period using financial reports from the local nongovernmental organization (NGO) implementer, as well as societal costs such as opportunity costs to mothers and delivery agents. We combined program impacts with these total costs to estimate incremental cost-effectiveness ratios (ICERs), as well as BCRs and the program's ROI for the government based on predictions of future lifetime wages and societal costs. Total costs per child were US$140 in the group-only arm and US$145 in the mixed-delivery arm. Because of higher intention-to-treat (ITT) impacts at marginally lower costs, the group-only model was the most cost-effective across all child outcomes. Focusing on child cognition in this arm, we estimated an ICER of a 0.37 standard deviation (SD) improvement in cognition per US$100 invested, a BCR of 15.5, and an ROI of 127%. A limitation of our study is that our estimated BCR and ROI necessarily make assumptions about the discount rate, income tax rates, and predictions of intervention impacts on future wages and schooling. We examine the sensitivity of our results to these assumptions. Conclusions: To the best of our knowledge, this study is the first economic evaluation of an effective ECD parenting intervention targeted to young children in sub-Saharan Africa (SSA) and the first to adopt a societal perspective in calculating cost-effectiveness that accounts for opportunity costs to delivery agents and program participants. Our cost-effectiveness and benefit-cost estimates are higher than most of the limited number of prior studies from LMIC settings providing information about costs. Our results represent a strong case for scaling similar interventions in impoverished rural settings, and, under reasonable assumptions about the future, demonstrate that the private and social returns of such investments are likely to largely outweigh their costs. Trial registration: This trial is registered at ClinicalTrials.gov, NCT03548558, June 7, 2018. American Economic Association RCT Registry trial AEARCTR-0002913.

Dietary patterns and stroke: a systematic review and re-meta-analysis.

The effect of diet on the development of stroke has recently achieved much interest by various research groups, but with inconclusive results. The aim of the present review was to systematically present and discuss the up to date available research regarding the relationship between adherence to dietary patterns and stroke. Studies included were observational and randomized clinical trials. Internet searches until May 31, 2014, retrieved 152 potentially relevant papers; of them, 34 were excluded on the basis that did not report data on humans, 3 were in language other than English, 2 were excluded because they had a cross-sectional design, 3 because they reported data on secondary prevention and 82 were excluded on the basis of irrelevant research. One article was a recent meta-analysis on Mediterranean diet, stroke, cognitive impairment and depression and was used as a basis for a re-meta-analysis with the additional papers published after the publication of the later meta-analysis. The existing evidence suggests that adherence to healthy dietary patterns (i.e., Mediterranean or DASH or plant based "prudent") was associated with reduced risk for stroke, whereas limited data exist supporting a detrimental effect of westernized dietary patterns. Moreover, the applied re-meta-analysis, based on a total sample of 195,875 participants enhanced the previously reported meta-analysis underlying a consistent, protective effect of higher adherence to the Mediterranean diet on stroke incidence (pooled relative risk 0.68, 95% CI 0.58, 0.79). Thus, a healthy dietary pattern exerts a beneficial effect on stroke incidence and mortality, adding a new direction toward stroke prevention on population level.

School-based programmes for preventing smoking.

Background: Helping young people to avoid starting smoking is a widely endorsed public health goal, and schools provide a route to communicate with nearly all young people. School-based interventions have been delivered for close to 40 years. Objectives: The primary aim of this review was to determine whether school smoking interventions prevent youth from starting smoking. Our secondary objective was to determine which interventions were most effective. This included evaluating the effects of theoretical approaches; additional booster sessions; programme deliverers; gender effects; and multifocal interventions versus those focused solely on smoking. Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Tobacco Addiction Group's Specialised Register, MEDLINE, EMBASE, PsycINFO, ERIC, CINAHL, Health Star, and Dissertation Abstracts for terms relating to school-based smoking cessation programmes. In addition, we screened the bibliographies of articles and ran individual MEDLINE searches for 133 authors who had undertaken randomised controlled trials in this area. The most recent searches were conducted in October 2012. Selection criteria: We selected randomised controlled trials (RCTs) where students, classes, schools, or school districts were randomised to intervention arm(s) versus a control group, and followed for at least six months. Participants had to be youth (aged 5 to 18). Interventions could be any curricula used in a school setting to deter tobacco use, and outcome measures could be never smoking, frequency of smoking, number of cigarettes smoked, or smoking indices. Data collection and analysis: Two reviewers independently assessed studies for inclusion, extracted data and assessed risk of bias. Based on the type of outcome, we placed studies into three groups for analysis: Pure Prevention cohorts (Group 1), Change in Smoking Behaviour over time (Group 2) and Point Prevalence of Smoking (Group 3). Main results: One hundred and thirty-four studies involving 428,293 participants met the inclusion criteria. Some studies provided data for more than one group. Pure Prevention cohorts (Group 1) included 49 studies (N = 142,447). Pooled results at follow-up at one year or less found no overall effect of intervention curricula versus control (odds ratio (OR) 0.94, 95% confidence interval (CI) 0.85 to 1.05). In a subgroup analysis, the combined social competence and social influences curricula (six RCTs) showed a statistically significant effect in preventing the onset of smoking (OR 0.49, 95% CI 0.28 to 0.87; seven arms); whereas significant effects were not detected in programmes involving information only (OR 0.12, 95% CI 0.00 to 14.87; one study), social influences only (OR 1.00, 95% CI 0.88 to 1.13; 25 studies), or multimodal interventions (OR 0.89, 95% CI 0.73 to 1.08; five studies). In contrast, pooled results at longest follow-up showed an overall significant effect favouring the intervention (OR 0.88, 95% CI 0.82 to 0.96). Subgroup analyses detected significant effects in programmes with social competence curricula (OR 0.52, 95% CI 0.30 to 0.88), and the combined social competence and social influences curricula (OR 0.50, 95% CI 0.28 to 0.87), but not in those programmes with information only, social influence only, and multimodal programmes. Change in Smoking Behaviour over time (Group 2) included 15 studies (N = 45,555). At one year or less there was a small but statistically significant effect favouring controls (standardised mean difference (SMD) 0.04, 95% CI 0.02 to 0.06). For follow-up longer than one year there was a statistically nonsignificant effect (SMD 0.02, 95% CI -0.00 to 0.02).Twenty-five studies reported data on the Point Prevalence of Smoking (Group 3), though heterogeneity in this group was too high for data to be pooled. We were unable to analyse data for 49 studies (N = 152,544).Subgroup analyses (Pure Prevention cohorts only) demonstrated that at longest follow-up for all curricula combined, there was a significant effect favouring adult presenters (OR 0.88, 95% CI 0.81 to 0.96). There were no differences between tobacco-only and multifocal interventions. For curricula with booster sessions there was a significant effect only for combined social competence and social influences interventions with follow-up of one year or less (OR 0.50, 95% CI 0.26 to 0.96) and at longest follow-up (OR 0.51, 95% CI 0.27 to 0.96). Limited data on gender differences suggested no overall effect, although one study found an effect of multimodal intervention at one year for male students. Sensitivity analyses for Pure Prevention cohorts and Change in Smoking Behaviour over time outcomes suggested that neither selection nor attrition bias affected the results. Authors' conclusions: Pure Prevention cohorts showed a significant effect at longest follow-up, with an average 12% reduction in starting smoking compared to the control groups. However, no overall effect was detected at one year or less. The combined social competence and social influences interventions showed a significant effect at one year and at longest follow-up. Studies that deployed a social influences programme showed no overall effect at any time point; multimodal interventions and those with an information-only approach were similarly ineffective. Studies reporting Change in Smoking Behaviour over time did not show an overall effect, but at an intervention level there were positive findings for social competence and combined social competence and social influences interventions.

Intra-aortic balloon counterpulsation in acute myocardial infarction complicated by cardiogenic shock (IABP-SHOCK II): final 12 month results of a randomised, open-label trial.

Background: In current international guidelines the recommendation for intra-aortic balloon pump (IABP) use has been downgraded in cardiogenic shock complicating acute myocardial infarction on the basis of registry data. In the largest randomised trial (IABP-SHOCK II), IABP support did not reduce 30 day mortality compared with control. However, previous trials in cardiogenic shock showed a mortality benefit only at extended follow-up. The present analysis therefore reports 6 and 12 month results. Methods: The IABP-SHOCK II trial was a randomised, open-label, multicentre trial. Patients with cardiogenic shock complicating acute myocardial infarction who were undergoing early revascularisation and optimum medical therapy were randomly assigned (1:1) to IABP versus control via a central web-based system. The primary efficacy endpoint was 30 day all-cause mortality, but 6 and 12 month follow-up was done in addition to quality-of-life assessment for all survivors with the Euroqol-5D questionnaire. A masked central committee adjudicated clinical outcomes. Patients and investigators were not masked to treatment allocation. Analysis was by intention to treat. This trial is registered at ClinicalTrials.gov, NCT00491036. Findings: Between June 16, 2009, and March 3, 2012, 600 patients were assigned to IABP (n=301) or control (n=299). Of 595 patients completing 12 month follow-up, 155 (52%) of 299 patients in the IABP group and 152 (51%) of 296 patients in the control group had died (relative risk [RR] 1·01, 95% CI 0·86-1·18, p=0·91). There were no significant differences in reinfarction (RR 2·60, 95% CI 0·95-7·10, p=0·05), recurrent revascularisation (0·91, 0·58-1·41, p=0·77), or stroke (1·50, 0·25-8·84, p=1·00). For survivors, quality-of-life measures including mobility, self-care, usual activities, pain or discomfort, and anxiety or depression did not differ significantly between study groups. Interpretation: In patients undergoing early revascularisation for myocardial infarction complicated by cardiogenic shock, IABP did not reduce 12 month all-cause mortality.

Assessment of Ramadan Education and Knowledge Among Diabetic Patients.

Background: During Ramadan, Muslims fast from dawn until dusk for one lunar month every year. Most of the Muslim patients with diabetes are unaware of the potential complications that can occur while fasting, such as hypoglycemia. The aim of this study is to assess the the patient education level and patients' overall awareness of any possible complications that could occur while fasting during Ramadan and to determine how these patients deal with these complications. Methods: We conducted a cross-sectional study and surveyed diabetic patients about their diabetes-related knowledge over a period of 4 months from the outpatient clinic at the Obesity, Endocrine, and Metabolism Center at King Fahad Medical City. Patients were included if they were ≥16 years and if they had been receiving treatment for at least 1 year before the study, irrespective of the medications used; patients were also asked about the presence or absence of complications. Results: This study included 477 patients (325 women and 152 men). Most patients (297; 62.3%) had type 2 diabetes. The patients' mean age was 39.72 ± 15.29 years, and the mean duration of diabetes was 10.80 ± 5.88 years. During the preceding Ramadan, 76% of patients reported fasting, whereas 58% said that they monitored their blood glucose levels once per day. Hypoglycemic episodes were reported in 60.3% of cases with type 2 diabetes and in 8.3% of cases with type 1 diabetes. Among those who had hypoglycemia, 2.8% of patients with type 1 diabetes and 17.8% with type 2 diabetes broke their fast. Finally, 54% of patients reported that their health care providers offered them instructions on diabetes management during Ramadan. Conclusions: Ramadan health education in diabetes can encourage, improve, and guide patients to change their lifestyles during Ramadan while minimizing the risk of acute complications.

Premature mortality attributable to socioeconomic inequality in England between 2003 and 2018: an observational study.

Background: Low socioeconomic position is consistently associated with increased risk of premature death. The aim of this study is to measure the aggregate scale of inequality in premature mortality for the whole population of England. Methods: We used mortality records from the UK Office for National Statistics to study all 2 465 285 premature deaths (defined as those before age 75 years) in England between Jan 1, 2003, and Dec 31, 2018. Socioeconomic position was defined using deciles of the Index of Multiple Deprivation: a measure of neighbourhood income, employment, education levels, crime, health, availability of services, and local environment. We calculated the number of expected deaths by applying mortality in the least deprived decile to other deciles, within the strata of age, sex, and time. The mortality attributable to socioeconomic inequality was defined as the difference between the observed and expected deaths. We also used life table modelling to estimate years-of-life lost attributable to socioeconomic inequality. Findings: 35·6% (95% CI 35·3-35·9) of premature deaths were attributable to socioeconomic inequality, equating to 877 082 deaths, or one every 10 min. The biggest contributors were ischaemic heart disease (152 171 excess deaths), respiratory cancers (111 083) and chronic obstructive pulmonary disease (83 593). The most unequal causes of death were tuberculosis, opioid use, HIV, psychoactive drugs use, viral hepatitis, and obesity, each with more than two-thirds attributable to inequality. Inequality was greater among men and peaked in early childhood and at age 40-49 years. The proportion of deaths attributable to inequality increased during the study period, particularly for women, because mortality rates among the most deprived women (excluding cardiovascular diseases) plateaued, and for some diseases increased. A mean of 14·4 months of life before age 75 years are lost due to socioeconomic inequality. Interpretation: One in three premature deaths are attributable to socioeconomic inequality, making this our most important public health challenge. Interventions that address upstream determinants of health should be prioritised. Funding: National Institute of Health Research; Wellcome Trust.

Is paternal oxytocin an oxymoron? Oxytocin, vasopressin, testosterone, oestradiol and cortisol in emerging fatherhood.

How do hormonal levels in men change from pregnancy to after the birth of their firstborn child, and what is the role of oxytocin, alone or in interplay with other hormones, in explaining variance in their parenting quality? We explored in 73 first-time fathers the development of five hormones that have been suggested to play a role in parenting: oxytocin (OT), vasopressin (AVP), testosterone (T), oestradiol (E2) and cortisol (Cort). In an extended group of fathers (N = 152) we examined associations with fathers' behaviour with their 2-month-old infants. OT and E2 showed stability from the prenatal to the postnatal assessments, whereas AVP and T decreased significantly, and Cort decreased marginally. OT on its own or in interplay with other hormones was not related to paternal sensitivity. Using an exploratory approach, the interaction between T and E2 emerged as relevant for fathers' sensitive parenting. Among fathers with high E2, high T was associated with lower sensitivity. Although we did not find evidence for the importance of OT as stand-alone hormone or in interplay with other hormones in this important phase in men's lives, the interaction between T and E2 in explaining variation in paternal behaviour is a promising hypothesis for further research. This article is part of the theme issue 'Interplays between oxytocin and other neuromodulators in shaping complex social behaviours'.

Association of various reproductive rights, domestic violence and marital rape with depression among Pakistani women.

Background: Depression among women is common in developing countries. Gender inequality can contribute to women's risk for depression. Lack of reproductive and sexual rights is an important marker of gender inequality and women do not have the freedom to express their reproductive and sexual needs in many parts of the world. Therefore we designed this study to determine the association of depression with lack of various reproductive rights and domestic violence among married women in Karachi, Pakistan. Methods: A case-control study with 152 cases and 152 controls, which included women 15-48 years, recruited from two teaching hospitals from 1st June 2007 through 31st August 2007. The SRQ was administered to all subjects. A cut off score of 8 was used to confirm cases of depression diagnosed by physicians, and to exclude cases of depression from the controls. Self-administered questionnaire was used to assess the risk factors. Results: 61% of the cases and 43% of the controls were ever abused by spouse and the frequency of marital rape was 33% in cases and 13% in controls. After adjusting for the effects of other variables in the model, less than 18 years of age at marriage (OR 2.00; 95% CI = 1.07, 3.7), decision for marriage by parents (OR 3.51; 95% CI = 1.67, 7.37), abuse by in laws (OR 4.91; 95% CI = 2.66, 9.06), <or= 3 hours per day spent with husband (OR 2.33; 95% CI = 1.34, 4.08), frequency of intercourse <or= 2 times per week (OR 1.85; 95% CI = 1.06, 3.22) and marital rape (OR 3.03; 95% CI = 1.50, 6.11) were associated with depression among women. Conclusion: In our study depression in married women was associated with younger age at marriage, lack of autonomy in marriage decisions, marital rape and domestic abuse by in-laws. Efforts should be directed towards creating awareness about the reproductive and sexual rights of women in Pakistan. Physicians should be trained to screen and identify women who may be at risk for psychological distress as a result of denial of reproductive rights so that they can support positive mental health outcomes through individual, family or marital counseling.

Cohort profile: Genetic data in the German Socio-Economic Panel Innovation Sample (SOEP-G).

The German Socio-Economic Panel (SOEP) serves a global research community by providing representative annual longitudinal data of respondents living in private households in Germany. The dataset offers a valuable life course panorama, encompassing living conditions, socioeconomic status, familial connections, personality traits, values, preferences, health, and well-being. To amplify research opportunities further, we have extended the SOEP Innovation Sample (SOEP-IS) by collecting genetic data from 2,598 participants, yielding the first genotyped dataset for Germany based on a representative population sample (SOEP-G). The sample includes 107 full-sibling pairs, 501 parent-offspring pairs, and 152 triads, which overlap with the parent-offspring pairs. Leveraging the results from well-powered genome-wide association studies, we created a repository comprising 66 polygenic indices (PGIs) in the SOEP-G sample. We show that the PGIs for height, BMI, and educational attainment capture 22∼24%, 12∼13%, and 9% of the variance in the respective phenotypes. Using the PGIs for height and BMI, we demonstrate that the considerable increase in average height and the decrease in average BMI in more recent birth cohorts cannot be attributed to genetic shifts within the German population or to age effects alone. These findings suggest an important role of improved environmental conditions in driving these changes. Furthermore, we show that higher values in the PGIs for educational attainment and the highest math class are associated with better self-rated health, illustrating complex relationships between genetics, cognition, behavior, socio-economic status, and health. In summary, the SOEP-G data and the PGI repository we created provide a valuable resource for studying individual differences, inequalities, life-course development, health, and interactions between genetic predispositions and the environment.

Depressive symptoms, racism, and school belonging: examining correlates of substance use behaviors among Black college students.

College is a context in which Black adults are at heightened risk for substance use behaviors and subsequently more harmful consequences. Increasingly, scholars are recognizing that to better understand shifts in patterns of substance use behaviors and health disparities among Black adults, mental health and racism are important factors to consider. Racism is multidimensional; thus, research is needed to investigate its multiple forms. Currently, it is unknown how the occurrence of depressive symptoms and various racism experiences influence patterns of substance use behaviors among Black college students. Further, while school belonging is evidenced to promote better health outcomes during adolescence, research is needed to understand school belonging in relation to substance use among Black college students. Using latent profile analysis (LPA), we identify patterns of substance use behaviors among Black college students (N = 152) and examine whether depressive symptoms, racism experiences (i.e., racial discrimination stress, internalized racism, negative police encounters), and school belonging are associated with the unique patterns. Latent profiles included indicators of substance use behavior frequency. Four patterns emerged: 1) low substance use, 2) predominant alcohol use, 3) co-use, 4) high polysubstance use. Depressive symptoms, internalized racism, and negative police encounters were significant correlates of patterns of substance use behaviors. School belonging, specifically, participation in student, cultural, spiritual, and Greek organizations, was also associated with profile membership. Findings suggest a need to integrate a broader understanding of how mental health and racism impacts the lives of Black college students, in addition to processes for supporting school belonging.

Feasibility and impact of a mental health chatbot on postpartum mental health: a randomized controlled trial.

Background: Perinatal mood disorders are common yet underdiagnosed and un- or undertreated. Barriers exist to accessing perinatal mental health services, including limited availability, time, and cost. Automated conversational agents (chatbots) can deliver evidence-based cognitive behavioral therapy content through text message-based conversations and reduce depression and anxiety symptoms in select populations. Such digital mental health technologies are poised to overcome barriers to mental health care access but need to be evaluated for efficacy, as well as for preliminary feasibility and acceptability among perinatal populations. Objective: To evaluate the acceptability and preliminary efficacy of a mental health chatbot for mood management in a general postpartum population. Study design: An unblinded randomized controlled trial was conducted at a tertiary academic center. English-speaking postpartum women aged 18 years or above with a live birth and access to a smartphone were eligible for enrollment prior to discharge from delivery hospitalization. Baseline surveys were administered to all participants prior to randomization to a mental health chatbot intervention or to usual care only. The intervention group downloaded the mental health chatbot smartphone application with perinatal-specific content, in addition to continuing usual care. Usual care consisted of routine postpartum follow up and mental health care as dictated by the patient's obstetric provider. Surveys were administered during delivery hospitalization (baseline) and at 2-, 4-, and 6-weeks postpartum to assess depression and anxiety symptoms. The primary outcome was a change in depression symptoms at 6-weeks as measured using two depression screening tools: Patient Health Questionnaire-9 and Edinburgh Postnatal Depression Scale. Secondary outcomes included anxiety symptoms measured using Generalized Anxiety Disorder-7, and satisfaction and acceptability using validated scales. Based on a prior study, we estimated a sample size of 130 would have sufficient (80%) power to detect a moderate effect size (d=.4) in between group difference on the Patient Health Questionnaire-9. Results: A total of 192 women were randomized equally 1:1 to the chatbot or usual care; of these, 152 women completed the 6-week survey (n=68 chatbot, n=84 usual care) and were included in the final analysis. Mean baseline mental health assessment scores were below positive screening thresholds. At 6-weeks, there was a greater decrease in Patient Health Questionnaire-9 scores among the chatbot group compared to the usual care group (mean decrease=1.32, standard deviation=3.4 vs mean decrease=0.13, standard deviation=3.01, respectively). 6-week mean Edinburgh Postnatal Depression Scale and Generalized Anxiety Disorder-7 scores did not differ between groups and were similar to baseline. 91% (n=62) of the chatbot users were satisfied or highly satisfied with the chatbot, and 74% (n=50) of the intervention group reported use of the chatbot at least once in 2 weeks prior to the 6-week survey. 80% of study participants reported being comfortable with the use of a mobile smartphone application for mood management. Conclusion: Use of a chatbot was acceptable to women in the early postpartum period. The sample did not screen positive for depression at baseline and thus the potential of the chatbot to reduce depressive symptoms in this population was limited. This study was conducted in a general obstetric population. Future studies of longer duration in high-risk postpartum populations who screen positive for depression are needed to further understand the utility and efficacy of such digital therapeutics for that population.

Empowering With PrEP (E-PrEP), a Peer-Led Social Media-Based Intervention to Facilitate HIV Preexposure Prophylaxis Adoption Among Young Black and Latinx Gay and Bisexual Men: Protocol for a Cluster Randomized Controlled Trial.

Background: Young black and Latinx, gay, bisexual, and other men who have sex with men (YBLGBM, aged 18-29 years) have among the highest rates of new HIV infections in the United States and are not consistently reached by existing prevention interventions. Preexposure prophylaxis (PrEP), an oral antiretroviral regimen taken daily by HIV-uninfected individuals to prevent HIV acquisition, is highly efficacious in reducing HIV acquisition and could help stop the HIV epidemic in YBLGBM. Use of social media (eg, Facebook, Twitter, online dating sites) is ubiquitous among young people, providing an efficient avenue to engage YBLGBM to facilitate PrEP adoption. Objective: Our overall goal was to develop and pilot test a theoretically grounded, social media-based, peer-led intervention to increase PrEP uptake in YBLGBM. We used diffusion of innovation and information-motivation-behavioral skills frameworks to (1) identify potential factors associated with interest in and adoption of PrEP among YBLGBM; (2) develop Empowering with PrEP (E-PrEP), a social media-based, peer-led intervention to increase PrEP uptake in YBLGBM; and (3) pilot test the feasibility and acceptability of E-PrEP, and determine its preliminary efficacy for increasing adoption of PrEP by YBLGBM. We describe the development and protocol for E-PrEP. Methods: Using a participatory research approach, we partnered with YBLGBM intervention development partners to develop a social media-based behavioral intervention to facilitate PrEP uptake, which involved an online messaging campaign disseminated by YBLGBM peer leaders to their existing online networks. We designed the 6-week campaign to provide education about PrEP, increase motivation to use PrEP, and facilitate access to PrEP. We then conducted a cluster-randomized trial of E-PrEP compared with an attention-matched general health control condition (E-Health) among YBLGBM aged 18 to 29 years to assess E-PrEP's feasibility, acceptability, preliminary efficacy for increasing self-reported intention to use PrEP, PrEP uptake, and impact on knowledge and attitudes about PrEP at 12-week follow-up (6 weeks after the end of the online campaign). Results: From October 2016 to March 2017, we developed, pretested, and refined E-PrEP with 6 YBLGBM intervention development partners. From May to June 2017, we recruited, enrolled, and randomly assigned 10 peer leaders (n=5 for each condition). The 10 peer leaders then recruited and enrolled 152 participants from their existing online networks (range 3-33 per peer leader), during June and July 2017. Intervention follow-up was completed after 12 weeks, in November 2017, with analyses underway. Conclusions: We hypothesize that, compared with E-Health, participants randomly assigned to E-PrEP will be more likely to express intention to use PrEP and greater PrEP uptake, and will also show changes in potential mediators of PrEP uptake (knowledge, attitudes, stigma, and access). A Web-based biobehavioral intervention model such as E-PrEP could be rapidly scaled even with limited resources and have significant population-level impact.

Body-related self-conscious emotions relate to physical activity motivation and behavior in men.

The aim of this study was to examine the associations between the body-related self-conscious emotions of shame, guilt, and pride and physical activity motivation and behavior among adult males. Specifically, motivation regulations (external, introjected, indentified, intrinsic) were examined as possible mediators between each of the body-related self-conscious emotions and physical activity behavior. A cross-sectional study was conducted with adult men (N = 152; Mage = 23.72, SD = 10.92 years). Participants completed a questionnaire assessing body-related shame, guilt, authentic pride, hubristic pride, motivational regulations, and leisure-time physical activity. In separate multiple mediation models, body-related shame was positively associated with external and introjected regulations and negatively correlated with intrinsic regulation. Guilt was positively linked to external, introjected, and identified regulations. Authentic pride was negatively related to external regulation and positively correlated with both identified and intrinsic regulations and directly associated with physical activity behavior. Hubristic pride was positively associated with intrinsic regulation. Overall, there were both direct and indirect effects via motivation regulations between body-related self-conscious emotions and physical activity (R(2) shame = .15, guilt = .16, authentic pride = .18, hubristic pride = .16). These findings highlight the importance of targeting and understanding self-conscious emotions contextualized to the body and links to motivation and positive health behavior among men.

Association of tiered restrictions and a second lockdown with COVID-19 deaths and hospital admissions in England: a modelling study.

Background: A second wave of COVID-19 cases in autumn, 2020, in England led to localised, tiered restrictions (so-called alert levels) and, subsequently, a second national lockdown. We examined the impact of these tiered restrictions, and alternatives for lockdown stringency, timing, and duration, on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and hospital admissions and deaths from COVID-19. Methods: We fit an age-structured mathematical model of SARS-CoV-2 transmission to data on hospital admissions and hospital bed occupancy (ISARIC4C/COVID-19 Clinical Information Network, National Health Service [NHS] England), seroprevalence (Office for National Statistics, UK Biobank, REACT-2 study), virology (REACT-1 study), and deaths (Public Health England) across the seven NHS England regions from March 1, to Oct 13, 2020. We analysed mobility (Google Community Mobility) and social contact (CoMix study) data to estimate the effect of tiered restrictions implemented in England, and of lockdowns implemented in Northern Ireland and Wales, in October, 2020, and projected epidemiological scenarios for England up to March 31, 2021. Findings: We estimated a reduction in the effective reproduction number (Rt) of 2% (95% credible interval [CrI] 0-4) for tier 2, 10% (6-14) for tier 3, 35% (30-41) for a Northern Ireland-stringency lockdown with schools closed, and 44% (37-49) for a Wales-stringency lockdown with schools closed. From Oct 1, 2020, to March 31, 2021, a projected COVID-19 epidemic without tiered restrictions or lockdown results in 280 000 (95% projection interval 274 000-287 000) hospital admissions and 58 500 (55 800-61 100) deaths. Tiered restrictions would reduce hospital admissions to 238 000 (231 000-245 000) and deaths to 48 600 (46 400-50 700). From Nov 5, 2020, a 4-week Wales-type lockdown with schools remaining open-similar to the lockdown measures announced in England in November, 2020-was projected to further reduce hospital admissions to 186 000 (179 000-193 000) and deaths to 36 800 (34 900-38 800). Closing schools was projected to further reduce hospital admissions to 157 000 (152 000-163 000) and deaths to 30 300 (29 000-31 900). A projected lockdown of greater than 4 weeks would reduce deaths but would bring diminishing returns in reducing peak pressure on hospital services. An earlier lockdown would have reduced deaths and hospitalisations in the short term, but would lead to a faster resurgence in cases after January, 2021. In a post-hoc analysis, we estimated that the second lockdown in England (Nov 5-Dec 2) reduced Rt by 22% (95% CrI 15-29), rather than the 32% (25-39) reduction estimated for a Wales-stringency lockdown with schools open. Interpretation: Lockdown measures outperform less stringent restrictions in reducing cumulative deaths. We projected that the lockdown policy announced to commence in England on Nov 5, with a similar stringency to the lockdown adopted in Wales, would reduce pressure on the health service and would be well timed to suppress deaths over the winter period, while allowing schools to remain open. Following completion of the analysis, we analysed new data from November, 2020, and found that despite similarities in policy, the second lockdown in England had a smaller impact on behaviour than did the second lockdown in Wales, resulting in more deaths and hospitalisations than we originally projected when focusing on a Wales-stringency scenario for the lockdown.

Parenting behavior is associated with the early neurobehavioral development of very preterm children.

Objective: There is an increasing focus on social and environmental factors that promote and support the early development of highly vulnerable children such as those born very preterm. The aim of this study was to assess the relationship between parenting behavior, parent-child synchrony, and neurobehavioral development in very preterm children at 24 months of age. Methods: Participants were 152 very preterm children (<30 weeks' gestation or <1250 g birth weight) and their parents/guardians. At 2 years' corrected age, parents/guardians and children completed a semistructured parent-child interaction task assessing dyad synchrony and parenting behavior (positive affect, negative affect, sensitivity, facilitation, and intrusiveness). Cognitive and motor development was assessed by using the Bayley Scales of Infant Development II, and the Infant Toddler Social and Emotional Assessment was used to assess socioemotional development (social-emotional competence and internalizing and externalizing behavior). Results: fter controlling for social risk, most parenting domains were associated with cognitive development, with parent-child synchrony emerging as the most predictive. Greater parent-child synchrony was also associated with greater social-emotional competence, as was parenting that was positive, warm, and sensitive. Parents who displayed higher levels of negative affect were more likely to rate their children as withdrawn, anxious, and inhibited, but, unexpectedly, higher negative affect was also associated with more optimal psychomotor development. Parenting was not associated with externalizing behaviors at this age. Conclusions: Specific parenting behaviors, particularly parent-child synchrony, were associated with neurobehavioral development. These findings have implications for the development of targeted parent-based interventions to promote positive outcomes across different developmental domains during the first 2 years of life for very preterm children.

Major depressive disorder is associated with cardiovascular risk factors and low Omega-3 Index.

Objective: Cardiovascular disease (CVD) and major depressive disorder (MDD) are frequent worldwide and have a high comorbidity rate. Omega-3 fatty acids have been suggested as disease modulators for both CVD and MDD. Therefore, we studied whether polyunsaturated fatty acids and the Omega-3 Index may represent markers for assessment of the cardiovascular risk in somatically healthy patients suffering from MDD. Method: We conducted a case-control study from July 2004 to December 2007 in 166 adults (86 inpatients with MDD but without CVD from the Department of Psychiatry and Psychotherapy and 80 age- and sex-matched healthy controls from an outpatient clinic of the Division of Preventive Cardiology, Ludwig Maximilian University of Munich, Germany). Information gathered at baseline included MDD diagnosis according to DSM-IV criteria, depression ratings, conventional cardiovascular risk factors, and fatty acid and interleukin-6 determinations. Fatty acid composition was analyzed according to the HS-Omega-3 Index methodology. During the study, patients received no supplementation with omega-3 fatty acids. The main inclusion criteria were the diagnosis of MDD according to DSM-IV and a 17-item Hamilton Depression Rating Scale (HDRS-17) score of at least 17. Treatment response and remission were defined using the HDRS-17. Results: Several conventional risk factors such as high triglyceride (mean, 152 mg/dL vs 100 mg/dL; P < .001) and fasting glucose (mean, 96 mg/dL vs 87 mg/dL; P = .005) values as well as greater waist circumference (mean, 97 cm vs 87 cm; P = .019) and higher body mass index (calculated as kg/m(2); mean, 26 vs 24; P = .011) were more prevalent in MDD patients in comparison with controls. The Omega-3 Index (mean, 3.9% vs 5.1%; P < .001) and individual omega-3 fatty acids were significantly lower in MDD patients. An Omega-3 Index < 4% was associated with high concentrations of the proinflammatory cytokine interleukin-6 (χ(2) = 7.8, P = .02). Conclusions: Conventional cardiovascular risk factors, the Omega-3 Index, and interleukin-6 levels indicated an elevated cardiovascular risk profile in MDD patients currently free of CVD. Our results support the employment of strategies to reduce the cardiovascular risk in still cardiovascularly healthy MDD patients by targeting conventional risk factors and the Omega-3 Index.

The cognitive consequences of envy: attention, memory, and self-regulatory depletion.

In a series of 4 experiments, we provide evidence that--in addition to having an affective component--envy may also have important consequences for cognitive processing. Our first experiment (N = 69) demonstrated that individuals primed with envy better attended to and more accurately recalled information about fictitious peers than did a control group. Studies 2 (N = 187) and 3 (N = 65) conceptually replicated these results, demonstrating that envy elicited by targets predicts attention and later memory for information about them. We demonstrate that these effects cannot be accounted for by admiration or changes in negative affect or arousal elicited by the targets. Study 4 (N = 152) provides evidence that greater memory for envied--but not neutral--targets leads to diminished perseverance on a difficult anagram task. Findings demonstrate that envy may play an important role in attention and memory systems and deplete limited self-regulatory resources available for acts of volition.

The comorbidity between eating disorders and anxiety disorders: prevalence in an eating disorder sample and anxiety disorder sample.

Objective: To investigate the prevalence of comorbid eating and anxiety disorders in women presenting for inpatient and outpatient treatment of an eating disorder and women presenting for outpatient treatment of an anxiety disorder. Methods: The prevalence of comorbidity was investigated from a sample of 152 women, which included 100 women presenting for treatment of an eating disorder and 52 women presenting for treatment of an anxiety disorder. Results: Of women presenting for treatment of an eating disorder, 65% also met criteria for at least one comorbid anxiety disorder; 69% of these reported the onset of the anxiety disorder to precede the onset of the eating disorder. Of the anxiety disorders diagnosed, social phobia was most frequently diagnosed (42%) followed by post-traumatic stress disorder (26%), generalised anxiety disorder (23%), obsessive-compulsive disorder (5%), panic/agoraphobia (3%) and specific phobia (2%). We also found that 13.5% of women presenting for anxiety treatment also met criteria for a comorbid eating disorder. Furthermore, 71% (n = 5) reported the onset of the anxiety disorder to precede the onset of the eating disorder.
