ObjectiveTo investigate the prevalence and clinical correlates of video polysomnography (vPSG)-confirmed rapid eye movement sleep behaviour disorder (RBD) in patients with major depressive disorder (MDD).MethodsThis is a clinic-based two-phase epidemiological study. In phase 1, patients with MDD were screened by a validated questionnaire, RBD Questionnaire-Hong Kong (RBDQ-HK). In phase 2, a subsample of both the screen-positive (RBDQ-HK >20) and screen–negative patients with MDD underwent further clinical and sleep assessment (vPSG) to confirm the diagnosis of RBD (MDD+RBD). Poststratification weighting method was used to estimate the prevalence of MDD+RBD. The total likelihood ratio and the probability of prodromal Parkinson’s disease (PD) were calculated from prodromal markers and risk factors, as per the Movement Disorder Society research criteria.ResultsA total of 455 patients with MDD were screened (median age (IQR)=52.66 (15.35) years, 77.58% woman, 43.74% positive). Eighty-one patients underwent vPSG and 12 of them were confirmed MDD+RBD. The prevalence of MDD+RBD was estimated to be 8.77% (95% CI: 4.33% to 16.93%), with possibly male predominance. MDD+RBD were associated with colour vision and olfaction deficit and a higher probability for prodromal PD.ConclusionsAlmost 9% of patients with MDD in the psychiatric outpatient clinic has vPSG-confirmed RBD. Comorbid MDD+RBD may represent a subtype of MDD with underlying α-synucleinopathy neurodegeneration. Systematic screening of RBD symptoms and necessity of vPSG confirmation should be highlighted for capturing this MDD subtype with a view to enhance personalised treatment and future neuroprotection to prevent neurodegeneration.

Background and objectivesWe sought to evaluate the effect of adult procedural sedation on cerebral oxygenation measured by near-infrared spectroscopy (rSo2levels), and to assess whether respiratory depression occurring during procedural sedation was associated with decreases in cerebral oxygenation.MethodsWe performed a prospective, observational preliminary study on a convenience sample of adult patients (>18 years) undergoing unscheduled procedural sedation in the ED from August 2017 to September 2018 at Hennepin County Medical Center in Minneapolis, Minnesota. The primary outcome measures were rSo2values by level of sedation achieved and the incidence of cerebral hypoxaemia during procedural sedation (absolute rSo2≤60 or decrease ≥20% from baseline). The secondary outcome is the decrease in rSo2during episodes of respiratory adverse events (AEs), defined by respiratory depression requiring supportive airway measures.ResultsWe enrolled 100 patients (53% female). The median (IQR) rSo2values (%) by each level of sedation achieved on the Observer Assessment of Alertness and Sedation (OAAS) scale 1–5, respectively, were 74 (69–79), 74 (70–79), 74 (69–79), 75 (69–80), 72 (68–76). The incidence of cerebral hypoxaemia at any point within the sedation (absolute rSo22reduction more than 20% from baseline value; the median (IQR) observed minimum rSo2in these patients was 58 (56–59). We observed respiratory depression in 65 patients via standard monitoring; of these, 39 (60%) required at least one supportive airway measure, meeting the definition of a respiratory AE. During these AEs, 15% (6/39) demonstrated cerebral hypoxaemia with a median (IQR) minimum rSo2of 58 (57–59). Four patients (4%) had cerebral hypoxaemia without a respiratory AE.ConclusionCerebral oximetry may represent a useful tool for procedural sedation safety research to detect potential subclinical changes that may be associated with risk, but appears neither sensitive nor specific for routine use in clinical practice.

ObjectiveThe role of the brain–gut axis is of increasing interest in IBD, as the link between common mental disorders and GI inflammation may be bidirectional. We performed a systematic review examining these issues.DesignWe searched EMBASE Classic and EMBASE, Medline, and APA PsychInfo (to 11 July 2021) for longitudinal follow-up studies examining effect of symptoms of anxiety or depression on subsequent adverse outcomes in IBD, or effect of active IBD on subsequent development of symptoms of anxiety or depression. We pooled relative risks (RRs) and HRs with 95% CIs for adverse outcomes (flare, escalation of therapy, hospitalisation, emergency department attendance, surgery or a composite of any of these) according to presence of symptoms of anxiety or depression at baseline, or RRs and HRs with 95% CIs for new onset of symptoms of anxiety or depression according to presence of active IBD at baseline.ResultsWe included 12 separate studies, recruiting 9192 patients. All 12 studies examined brain-to-gut effects. Anxiety at baseline was associated with significantly higher risks of escalation of therapy (RR=1.68; 95% CI 1.18 to 2.40), hospitalisation (RR=1.72; 95% CI 1.01 to 2.95), emergency department attendance (RR=1.30; 95% CI 1.21 to 1.39), or a composite of any adverse outcome. Depression at baseline was associated with higher risks of flare (RR=1.60; 95% CI 1.21 to 2.12), escalation of therapy (RR=1.41; 95% CI 1.08 to 1.84), hospitalisation (RR=1.35; 95% CI 1.17 to 1.57), emergency department attendance (RR=1.38; 95% CI 1.22 to 1.56), surgery (RR=1.63; 95% CI 1.19 to 2.22) or a composite of any of these. Three studies examined gut-to-brain effects. Active disease at baseline was associated with future development of anxiety or depression (RR=2.24; 95% CI 1.25 to 4.01 and RR=1.49; 95% CI 1.11 to 1.98, respectively).ConclusionBidirectional effects of the brain–gut axis are present in IBD and may influence both the natural history of the disease and psychological health.

BackgroundThe number of adults across the globe with significant depressive symptoms has grown substantially during the COVID-19 pandemic. The extant literature supports exercise as a potent behaviour that can significantly reduce depressive symptoms in clinical and non-clinical populations.ObjectiveUsing a suite of mobile applications, at-home exercise, including high intensity interval training (HIIT) and/or yoga, was completed to reduce depressive symptoms in the general population in the early months of the pandemic.MethodsA 6-week, parallel, multiarm, pragmatic randomised controlled trial was completed with four groups: (1) HIIT, (2) Yoga, (3) HIIT+yoga, and (4) waitlist control (WLC). Low active, English-speaking, non-retired Canadians aged 18–64 years were included. Depressive symptoms were measured at baseline and weekly following randomisation.ResultsA total of 334 participants were randomised to one of four groups. No differences in depressive symptoms were evident at baseline. The results of latent growth modelling showed significant treatment effects in depressive symptoms for each active group compared with the WLC, with small effect sizes (ESs) in the community-based sample of participants. Treatment groups were not significantly different from each other. Effect sizes were very large (eg, week 6 ES range=−2.34 to −2.52) when restricting the analysis only to participants with high depressive symptoms at baseline.ConclusionsAt-home exercise is a potent behaviour to improve mental health in adults during the pandemic, especially in those with increased levels of depressive symptoms. Promotion of at-home exercise may be a global public health target with important personal, social and economic implications as the world emerges scathed by the pandemic.Trial registration numberNCT04400279.

Survival analysis is routinely used to assess differences between groups in relapse prevention and treatment discontinuation studies involving people with long-term psychiatric conditions. The actual outcome in survival analysis is ‘time to event’, yet, in the mental health field, there has been little consideration of whether a temporary delay to relapse is clinically relevant in a condition that can last for decades. Moreover, in psychiatric drug trials, a pattern of elevated early relapses following randomisation to placebo or no treatment is common. This may be the result of the withdrawal of previous treatment leading to physiological withdrawal effects, which may be mistaken for relapse, or genuine relapse precipitated by the process of withdrawal. Such withdrawal effects typically produce converging survival curves eventually. They inevitably lead to differences in time to relapse, even when there is little or no difference in the cumulative risk of relapse at final follow-up. Therefore, statistical tests based on survival analyses can be misleading because they obscure these withdrawal effects. We illustrate these difficulties in a trial of antipsychotic reduction versus maintenance, and a trial of prophylactic esketamine in people with treatment-resistant depression. Both illustrate withdrawal-related effects that underline the importance of long-term follow-up and question the use of tests based on time to event. Further discussion of the most relevant outcome and appropriate approach to analysis, and research on patient and carer preferences is important to inform the design of future trials and interpretation of existing ones.

AimsTo examine independent and interactive associations of ophthalmic and systemic conditions with incident dementia.MethodsOur analysis included 12 364 adults aged 55–73 years from the UK Biobank cohort. Participants were assessed between 2006 and 2010 at baseline and were followed up until the early of 2021. Incident dementia was ascertained using hospital inpatient, death records and self-reported data.ResultsOver 1 263 513 person-years of follow-up, 2304 cases of incident dementia were documented. The multivariable-adjusted HRs (95% CI) for dementia associated with age-related macular degeneration (AMD), cataract, diabetes-related eye disease (DRED) and glaucoma at baseline were 1.26 (1.05 to 1.52), 1.11 (1.00 to 1.24), 1.61 (1.30 to 2.00) and (1.07 (0.92 to 1.25), respectively. Diabetes, heart disease, stroke and depression at baseline were all associated with an increased risk of dementia. Of the combination of AMD and a systemic condition, AMD-diabetes was associated with the highest risk for incident dementia (HR (95% CI): 2.73 (1.79 to 4.17)). Individuals with cataract and a systemic condition were 1.19–2.29 times more likely to develop dementia compared with those without cataract and systemic conditions. The corresponding number for DRED and a systemic condition was 1.50–3.24. Diabetes, hypertension, heart disease, depression and stroke newly identified during follow-up mediated the association between cataract and incident dementia as well as the association between DRED and incident dementia.ConclusionsAMD, cataract and DRED but not glaucoma are associated with an increased risk of dementia. Individuals with both ophthalmic and systemic conditions are at higher risk of dementia compared with those with an ophthalmic or systemic condition only.

BackgroundCompared with traditional screening questionnaires, computerised adaptive tests for severity of depression (CAT-DI) and computerised adaptive diagnostic modules for depression (CAD-MDD) show improved precision in screening for major depressive disorder. CAT measures have been tailored to perinatal women but have not been studied in low-income women of colour despite high rates of perinatal depression (PND).ObjectiveThis study aimed to examine the concordance between CAT and traditional measures of depression in a sample of primarily low-income black and Latina women.MethodsIn total, 373 women (49% black; 29% Latina) completed the Patient Health Questionnaire-9 (PHQ-9), CAD-MDD and CAT-DI at 845 visits across pregnancy and postpartum. We examined the concordance between continuous CAT-DI and PHQ-9 scores and between binary measures of PND diagnosis on CAD-MDD and the PHQ-9 (cut-off score >10). We examined cases with a positive PND diagnosis on the CAD-MDD but not on the PHQ-9 (‘missed’ cases) to determine whether clinic notes were consistent with CAD-MDD results.FindingsCAT-DI and PHQ-9 scores were significantly associated (concordance correlation coefficient=0.67; 95% CI 0.58 to 0.74). CAD-MDD detected 5% more case of PND compared with PHQ-9 (pConclusionsCAD-MDD detected 5% more cases of PND in women of colour compared with traditional tests, and the majority of these cases were verified by clinician notes.Clinical implicationsUse of CAT in routine clinic care may address health disparities in PND screening.

IntroductionExercise training before lung resection for non-small cell lung cancer is believed to decrease postoperative complications (POC) by improving cardiorespiratory fitness. However, this intervention lacks a strong evidence base.AimTo assess the effectiveness of preoperative exercise training compared with usual care on POC and other secondary outcomes in patients with scheduled lung resection.MethodsA systematic search of randomised trials was conducted by two authors. Meta-analysis was performed, and the effect of exercise training was estimated by risk ratios (RR) and mean differences, with their CIs. Clinical usefulness was estimated according to minimal important difference values (MID).ResultsFourteen studies involving 791 participants were included. Compared with usual care, exercise training reduced overall POC (10 studies, 617 participants, RR 0.58, 95% CI 0.45 to 0.75) and clinically relevant POC (4 studies, 302 participants, Clavien-Dindo score ≥2 RR 0.42, 95% CI 0.25 to 0.69). The estimate of the effect of exercise training on mortality was very imprecise (6 studies, 456 participants, RR 0.66, 95% CI 0.20 to 2.22). The main risks of bias were a lack of participant blinding and selective reporting. Exercise training appeared to improve exercise capacity, pulmonary function and also quality of life and depression, although the clinical usefulness of the changes was unclear. The quality of the evidence was graded for each outcome.ConclusionPreoperative exercise training leads to a worthwhile reduction in postoperative complications. These estimates were both accurate and large enough to make recommendations for clinical practice.

BackgroundThe Coronavirus Aid, Relief, and Economic Security Act of 2020 provided ‘economic impact payments’ (EIPs) of $1200 to US adults with annual personal income of $75 000 or less. This study examined the prospective association between EIP receipt and mental health outcomes.MethodsA nationally representative sample of 3169 middle-income and low-income US adults completed a baseline assessment of their health and well-being in May–June 2020 and a 3-month follow-up assessment during the period of the COVID-19 pandemic when EIPs were distributed.ResultsControlling for sociodemographic characteristics, EIP recipients had higher odds of reporting a positive COVID-19 test, endorsing a history of post-traumatic stress disorder and reporting any illicit drug use in the past month than participants who did not receive EIP. Participants who did not receive EIP were more likely to report a history of anxiety disorder or alcohol use disorder and recent suicidal ideation than EIP recipients. There was no association between EIP receipt and financial distress, although over one-third to over half of EIP recipients were not employed at baseline. Between baseline and 3-month follow-up, receipt of EIP was significantly associated with reduced medical conditions and alcohol use problems, but increased depression, suicidal ideation and COVID-19 era-related stress.ConclusionThe EIP provided a brief income stimulus to many adults in need but was not associated with improvements in financial distress or mental health among middle-income and low-income recipients. Long-term income security and employment may be more important to improving and sustaining positive mental health outcomes.

BackgroundThis study was conducted to systematically review the existing literature examining the prevalence of anxiety among hospital staff and identifying the contributing factors to address the complications of this disorder and develop effective programmes for reducing the complications of this mental health problem.MethodsWe searched the electronic databases including PubMed, EMBASE, Scopus, Web of Science and Google Scholar from January 2020 to February 2021. To perform meta-analysis, the random effects model was used. To assess the statistical heterogeneity of the included studies, the I2index was used, and 95% CI was estimated. Data analysis was performed by R software.ResultsIn the final analysis, 46 articles with the total sample size of 61 551 hospital staff members were included. Accordingly, anxiety prevalence among healthcare workers (HCWs) was 26.1% (95% CI 19% to 34.6%). The prevalence rates of anxiety in health technicians and medical students were 39% (95% CI 13% to 73%) and 36% (95% CI 15% to 65%), respectively, indicating a much higher prevalence than other hospital staff members. Furthermore, a positive significant relationship between prevalence of anxiety among HCWs and their age was approved (pConclusionThe findings show a moderately high prevalence rate of anxiety in hospital staff. Due to the high prevalence of this mental health problem in health technicians, medical students and frontline health workers, it is highly suggested that healthcare institutions offer mental health programmes for these working groups in order to appropriately manage anxiety during the COVID-19 pandemic.

BackgroundFour ablative neurosurgical procedures are used in the treatment of refractory psychiatric illness. The long-term effects of these procedures on psychiatric symptoms across disorders has never been synthesised and meta-analysed.MethodsA preregistered systematic review was performed on studies reporting clinical results following ablative psychiatric neurosurgery. Four possible outcome measures were extracted for each study: depression, obsessive–compulsive symptoms, anxiety and clinical global impression. Effect sizes were calculated using Hedge’s g. Equipercentile linking was used to convert symptom scores to a common metric. The main outcome measures were the magnitude of improvement in depression, obsessive compulsive symptoms, anxiety and clinical global impression. The secondary outcome was a subgroup analysis comparing the magnitude of symptom changes between the four procedures.ResultsOf 943 articles, 43 studies reporting data from 1414 unique patients, were included for pooled effects estimates with a random-effects meta-analysis. Results showed that there was a large effect size for improvements in depression (g=1.27; pConclusionsContemporary ablative neurosurgical procedures were significantly associated with improvements in depression, obsessive–compulsive symptoms, anxiety and clinical global impression.PROSPERO registration numberCRD42020164784.

The number of people living with and beyond cancer is rising rapidly. With earlier detection and better treatments many people are living for years following a diagnosis of cancer. Healthcare systems need to adapt to manage this demand and better meet the needs of this growing population.1 The consequences of cancer and its treatment are common, can arise at any point and may be long lasting.2 They can have a significant impact on daily life and include a range of physical symptoms and late effects such as pain, fatigue, bowel dysfunction; psychological concerns such as anxiety, depression and fear of recurrence; and social impacts including disruption to previously enjoyed activities, ability to work and relationships.3 Lifestyle changes and long-term medications to reduce the risk of recurrence, hospital appointments, routine surveillance and monitoring for signs of potential disease progression can create additional burden. People may lack confidence and struggle to manage the impact on their daily lives resulting in disrupted lives and futures.4 This can exacerbate mental health problems such as depression and anxiety. Low confidence to self-manage and depression have been associated with worse health and well-being outcomes up to 2 years after diagnosis.5 In addition, as most people are diagnosed with cancer in later life, many are also living with long-term conditions which can exacerbate problems further.6 Understanding how best to support people to manage the consequences of cancer and its treatment to reduce health crises and quality of life is a global concern.7 The good news is that appropriate support can reduce health crises, enhance confidence to manage and improve mental health, quality of life and other outcomes.8 9 The National Health Service (NHS) Long Term Plan10 states that by 2021 ‘ where appropriate every person diagnosed with cancer …

ObjectiveTo investigate subjective cognitive decline (SCD) in relation to β-amyloid pathology and to test for associations with anxiety, depression, objective cognition and family history of dementia in the Insight 46 study.MethodsCognitively unimpaired ~70-year-old participants, all born in the same week in 1946 (n=460, 49% female, 18% amyloid-positive), underwent assessments including the SCD-Questionnaire (MyCog). MyCog scores were evaluated with respect to18F-Florbetapir-PET amyloid status (positive/negative). Associations with anxiety, depression, objective cognition (measured by the Preclinical Alzheimer Cognitive Composite, PACC) and family history of dementia were also investigated. The informant’s perspective on SCD was evaluated in relation to MyCog score.ResultsAnxiety (mean (SD) trait anxiety score: 4.4 (3.9)) was associated with higher MyCog scores, especially in women. MyCog scores were higher in amyloid-positive compared with amyloid-negative individuals (adjusted means (95% CIs): 5.3 (4.4 to 6.1) vs 4.3 (3.9 to 4.7), p=0.044), after accounting for differences in anxiety. PACC (mean (SD) −0.05 (0.68)) and family history of dementia (prevalence: 23.9%) were not independently associated with MyCog scores. The informant’s perception of SCD was generally in accordance with that of the participant.ConclusionsThis cross-sectional study demonstrates that symptoms of SCD are associated with both β-amyloid pathology, and more consistently, trait anxiety in a population-based cohort of older adults, at an age when those who are destined to develop dementia are still likely to be some years away from symptoms. This highlights the necessity of considering anxiety symptoms when assessing Alzheimer’s disease pathology and SCD.

In November 2019, a 75 year-old woman with a history of diabetes mellitus and major depression with psychotic features underwent a radical vulvectomy, including the resection of the external meatus of the urethra and the distal third of the vagina, for a well-differentiated infiltrating squamous

ObjectivesDepression affects an estimated 7% of the adult population at an estimated cost of over US$200 billion/year in the USA. Complete, transparent reporting of clinical trial data facilitates valid estimates of treatment efficacy. In the USA, ClinicalTrials.gov increases transparency through mandatory prospective trial registration and outcome reporting. We examined characteristics of the transparent reporting of depression treatment studies registered in ClinicalTrials.gov.DesignCross sectional.Setting and participantsUS-based studies identified in a search of ClinicalTrials.gov with depression as the condition, enrolling ages 18 and older, and completed between 1 January 2008 and 1 May 2019.InterventionsAll interventions were included.Main outcomes and measuresThe main outcome was whether any results were reported prior to 1 May 2020. Data were extracted regarding inclusion and exclusion criteria, publications related to the study and specification of hypotheses.Results725 studies involving 156 634 patients met inclusion criteria. 416 (57.4%) of the studies posted some results. However, statistical test results were not included in 230 studies (55.3%). Most studies had data that could have been analysed and reported. Compared with studies without results, studies with any results were more likely to have hypotheses, include drug treatment conditions, and to have publications related to the study.ConclusionsRequired study registration does not always result in transparent outcome reporting. Better compliance with mandated reporting and improved reporting standards would facilitate a more comprehensive representation of depression treatment research.

ObjectivesPhysical inactivity is a risk factor for premature mortality and several non-communicable diseases. The purpose of this study was to estimate the global burden associated with physical inactivity, and to examine differences by country income and region.MethodsPopulation-level, prevalence-based population attributable risks (PAR) were calculated for 168 countries to estimate how much disease could be averted if physical inactivity were eliminated. We calculated PARs (percentage of cases attributable to inactivity) for all-cause mortality, cardiovascular disease mortality and non-communicable diseases including coronary heart disease, stroke, hypertension, type 2 diabetes, dementia, depression and cancers of the bladder, breast, colon, endometrium, oesophagus, stomach and kidney.ResultsGlobally, 7.2% and 7.6% of all-cause and cardiovascular disease deaths, respectively, are attributable to physical inactivity. The proportions of non-communicable diseases attributable to physical inactivity range from 1.6% for hypertension to 8.1% for dementia. There was an increasing gradient across income groups; PARs were more than double in high-income compared with low-income countries. However, 69% of total deaths and 74% of cardiovascular disease deaths associated with physical inactivity are occurring in middle-income countries, given their population size. Regional differences were also observed, with the PARs occurring in Latin America/Caribbean and high-income Western and Asia-Pacific countries, and the lowest burden occurring in Oceania and East/Southeast Asia.ConclusionThe global burden associated with physical inactivity is substantial. The relative burden is greatest in high-income countries; however, the greatest number of people (absolute burden) affected by physical inactivity are living in middle-income countries given the size of their populations.

BackgroundDepression has substantial and enduring impacts for adolescents, particularly those living in poverty. Yet, evidence on its determinants in low-income countries remains scarce. We examined the social determinants of depressive symptoms for Tanzanian adolescents.MethodsWe used cross-sectional data for 2458 adolescents (aged 14–19), to describe associations with depressive symptoms within and across five domains—demographic, economic, neighbourhood, environmental and social-cultural—using linear mixed models. We estimated depressive symptoms using the 10-item Centre for Epidemiological Studies Depression Scale, which ranges from 0 to 30 and increases with additional symptoms.ResultsFactors associated with depressive symptoms in the fully adjusted models included experiencing five or more household economic shocks (β=2.40; 95% CI 1.48 to 3.32), experiencing droughts/floods (β=0.76; 95% CI 0.36 to 1.17), being in a relationship (β=1.82; 95% CI 1.30 to 2.33), and having moderate (β=1.26; 95% CI 0.80 to 1.71) or low (β=2.27; 95% CI 1.81 to 2.74) social support. Exclusive schooling was protective compared with being engaged in both school and paid work (β=1.07; 95% CI 0.05 to 2.61) and not engaged in either (β=0.73; 95% CI 0.24 to 1.22). Household size and relationship status were more important factors for girls, while employment status, and extreme precipitation were more important for boys.ConclusionMental health is associated with determinants from multiple domains. Results suggest that environmental shocks related to climate change contribute to poor mental health in adolescents, highlighting an important area for intervention and research.

The efficacy of antidepressants in the acute treatment of moderate-to-severe depression remains a controversial issue. The minimal important difference (MID) is relevant to judge the clinical significance of treatment effects. In this analysis paper, we discuss estimates of the MID for common depression outcome measures.For the Hamilton Depression Rating Scale 17-item Version (HDRS-17), according to both anchor-based and distribution-based approaches, MID estimates range from 3 to 8 points, and the most accurate values are likely between 3 and 5 points. For the 6-item version (HDRS-6), MID estimates range between 2 and 4 points. For both the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Beck Depression Inventory II (BDI-II), MID estimates range between 3 and 9 points, with estimates of 3–6 points likely being the most accurate. Quality of life appears to be more important to patients than core depression symptoms. We thus also evaluated the Short-Form 36 (SF-36) mental component score, a popular mental-health-related quality of life measure. Its MID estimate is likely about 5 points. By contrast, the average treatment effects of antidepressants on the HDRS-17, HDRS-6, MADRS, BDI-II and SF-36 are 2 points, 1.5 points, 3 points, 2 points and 3–5 points, respectively.In conclusion, the efficacy of antidepressants in the acute treatment of moderate-to-severe depression consistently fails to exceed the lower bound of the MID estimates for common depression outcome measures. The clinical significance of antidepressants thus remains uncertain and we call for more research on quality of life measures, which are the patients’ most valued outcome domains.

BackgroundResearch has linked food insecurity to mental health problems, though little is known about this relationship among Canadian youth. We investigate the association between food insecurity severity and mental illnesses in a nationally representative youth sample.MethodsWe sampled 55 700 youth 12–24 years from recent cycles of Canadian Community Health Survey. Household food insecurity was measured using a standard 18-item questionnaire. We fitted Poisson regressions on self-rated mental health and diagnosed mood and anxiety disorders, controlling for sociodemographic confounders. Clinical assessments of emotional distress, major depression and suicidal ideation were examined in subsamples with available data. We stratified the sample by gender, age and survey cycle to test potential demographic heterogeneity.ResultsOne in seven youth lived in marginal (5.30%), moderate (8.08%) or severe (1.44%) food insecurity. Results showed that food insecurity was associated with higher likelihood of every mental health problem examined. The association was graded, with more severe food insecurity linked to progressively worse mental health. Notably, marginal, moderate and severe food insecurity were associated with 1.77, 2.44 and 6.49 times higher risk of suicidal thoughts, respectively. The corresponding relative risk for mood disorders were 1.57, 2.00 and 2.89; those for anxiety disorders were 1.41, 1.65 and 2.58. Moderate food insecurity was more closely associated with mental health problems in 18–24 year olds than in 12–17 year olds.ConclusionsFood insecurity severity was associated with poorer mental health among Canadian youth independent of household income and other socioeconomic differences. Targeted policy intervention alleviating food insecurity may improve youth mental health.

ObjectiveTo identify subgroups of former National Football League (NFL) players using latent profile analysis (LPA) and examine their associations with total years of participation (TYP) and self-reported lifetime sport-related concussion history (SR-CHx).MethodsFormer NFL players (N=686) aged 50–70 years, with an average 18.0 TYP (±4.5) completed a questionnaire. SR-CHx distributions included: low (0–3; n=221); intermediate (4–8; n=209) and high (9+; n=256). LPA measures included: Quality of Life in Neurological Disorders Emotional–Behavioral Dyscontrol, Patient Reported Outcomes Measurement Information System Cognitive Function, Emotional Support, Self-Efficacy, Meaning and Purpose, Physical Function, Pain Interference, Participation in Social Roles and Activities, Anxiety, Depression, Fatigue, and Sleep Disturbance. Demographic, medical/psychiatric history, current psychosocial stressors, TYP and SR-CHx were compared across latent profiles (LPs).ResultsA five profile solution emerged: (LP1) global higher functioning (GHF; 26.5%); (LP2) average functioning (10.2%); (LP3) mild somatic (pain and physical functioning) concerns (22.0%); (LP4) somatic and cognitive difficulties with mild anxiety (SCA; 27.5%); LP5) global impaired functioning (GIF; 13.8%). The GIF and SCA groups reported the largest number ofe- medical/psychiatric conditions and higher psychosocial stressor levels. SR-CHx was associated with profile group (χ2(8)=100.38, pConclusionsFive distinct profiles of self-reported functioning were identified among former NFL players. Several comorbid factors (ie, medical/psychiatric diagnoses and psychosocial stressors) and SR-CHx were associated with greater neurobehavioural and psychosocial dysfunction.

IntroductionThe ‘golden hour’ is a universal paradigm that suggests trauma patients have lower morbidity and mortality when provided with medical care within 1 hour after injury. The objective of this study was to examine whether transport time from point of injury to a military treatment facility (MTF) in-theatre was associated with patient-reported outcomes, such as post-traumatic stress disorder (PTSD), depression and quality of life (QOL), among US service members with combat-related injury.MethodsParticipants were injured between March 2003 and March 2016 and completed standardised assessments of PTSD, depression and QOL for theWounded Warrior Recovery Project (WWRP) between January 2013 and November 2017. Multivariable regressions were used to assess the relationship between transport time (≤1 hour or >1 hour from injury to MTF) and positive screens for PTSD and depression, and QOL, respectively.Overall, 45.6% of participants (n=879) arrived at an MTF within 1 hour postinjury. About 8 years passed between when participants were injured on deployment and when they completed their first WWRP assessment. Approximately 48% of participants screened positive for PTSD and 51.3% for depression, with a mean QOL score of 0.513 (SD=0.150). After adjusting for covariates, transport time was not significantly associated with PTSD (OR 1.04, 95% CI 0.79 to 1.38; p=0.77), depression (OR 0.92, 95% CI 0.69 to 1.21; p=0.55) or QOL (β=0.009; p=0.38).ConclusionTransport time was not associated with patient-reported outcomes among US service members with combat-related injury. These findings are important as we seek to understand how combat casualties may be affected by extended medical evacuation or transport times anticipated in future expeditionary operations.

ObjectivesSurgical procedures targeting the anterior limb of the internal capsule (aLIC) can be effective in patients with selected treatment-refractory obsessive-compulsive disorder (OCD). The aLIC consists of white-matter tracts connecting cortical and subcortical structures and show a topographical organisation. Here we assess how aLIC streamlines are affected in OCD compared with healthy controls (HCs) and which streamlines are related with post-capsulotomy improvement.MethodsDiffusion-weighted MRI was used to compare white-matter microstructure via the aLIC between patients with OCD (n=100, 40 women, mean of age 31.8 years) and HCs (n=88, 39 women, mean of age 29.6 years). For each individual, the fractional anisotropy (FA) and streamline counts were calculated for each white-matter fibre bundle connecting a functionally defined prefrontal and subcortical region. Correlations between tractography measures and pre-capsulotomy and post-capsulotomy clinical outcomes (in obsessive-compulsive, anxiety and depression scores 6 months after surgery) were assessed in 41 patients with OCD.ResultsHierarchical clustering dendrograms show an aLIC organisation clustering lateral and dissociating ventral and dorsal prefrontal–thalamic streamlines, findings highly relevant to surgical targeting. Compared with HCs, patients with OCD had lower aLIC FA across multiple prefrontal cortical–subcortical regions (pConclusionsThese findings shed light on the critical role of the aLIC in OCD and may potentially contribute towards precision targeting to optimise outcomes in OCD.

ObjectiveThe aim of this report is to investigate the nature of the relationship between depression and condomless sex (CLS) among gay, bisexual and other men who have sex with men (GBMSM).MethodsData are from the Antiretrovirals, Sexual Transmission Risk and Attitude (ASTRA) study of people living with HIV and attending one of eight HIV outpatient clinics in England (2011–2012) and the Attitudes to and Understanding of Risk of Acquisition of HIV (AURAH) study of HIV-negative/unknown status individuals attending one of 20 genitourinary medicine clinics in England (2013–2014). This analysis included GBMSM only. For each study, the prevalence of depressive symptoms (Patient Health Questionnaire-9 score ≥10) was presented according to three categories of sex in the past 3 months (considering anal/vaginal sex with men/women and anal sex with men in separate definitions): (1) no sex, (2) condom-protected sex only and (3) CLS. Multinomial logistic regression with ‘condom-protected sex only’ as the reference group was used to adjust for age and (for ASTRA participants) time since HIV diagnosis.ResultsThere were opposing associations of depression with recent sexual behaviour: the prevalence of depression was higher among those who reported no sex and those who reported CLS, compared with those who reported condom-protected sex only. Among the 2170 HIV-positive GBMSM in ASTRA, considering anal/vaginal sex with men/women, the prevalence of depressive symptoms was 32%, 20% and 28%, respectively, among men reporting no sex (n=783), condom-protected sex only (n=551) and CLS (n=836) (global pConclusionsDepression may be linked both to lack of sexual activity and to sexual risk taking. When investigating associations between depression and CLS, it is important to separate out individuals reporting condom-protected sex only from those reporting no sex.

BackgroundMore than half of women with symptoms suggestive of myocardial ischaemia have no obstructive coronary artery disease (CAD), yet they face a higher risk of cardiovascular mortality and morbidity. Both vital exhaustion (VE) and depression have been linked to adverse cardiovascular prognosis in patients with CAD. We aimed to assess whether symptomatic women with no obstructive CAD are more vitally exhausted compared with asymptomatic women. Furthermore, we investigated the overlap between the constructs of VE and depression.MethodsPrevalence and burden of VE was assessed in symptomatic women with no obstructive CAD (n=1.266) and asymptomatic women (n=2.390). Among symptomatic women, we also assessed chest pain characteristics and symptoms of Hospital Anxiety and Depression Questionnaire.FindingsMedian (IQR) VE score was 4 (1-9) and 2 (0–5) in symptomatic and asymptomatic women, respectively (age adjusted, pConclusionsWomen with chest pain and no obstructive CAD are more vitally exhausted compared with asymptomatic women. PCCA showed that VE is distinct from depression in symptomatic women.Clinical implicationsMental health screening focusing on depressive symptomatology in women with chest pain presenting with symptoms of mental and physical exhaustion may overlook VE in these patients.

Rationale Body dissatisfaction is prevalent in mid-adolescence and may be associated with the onset of depression. Objective The study assessed the influence of body dissatisfaction on the occurrence of later depressive episodes in a population-based sample of British adolescents. Method Participants were 2078 females and 1675 males from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Logistic regression was used to test if body dissatisfaction at 14 years old predicted the onset of depressive episodes at 18 years old, controlling for baseline depression. Results Among females, body dissatisfaction predicted mild (OR=1.63, 95% CI=1.31, 2.04), moderate (OR=1.67, 95% CI=1.28, 2.18) and severe depressive episodes (OR=1.84, 95% CI=1.09, 3.12). Among males, body dissatisfaction predicted mild (OR=1.50, 95% CI=1.00, 2.25) and severe depressive episodes (OR=2.85, 95% CI=1.18, 6.87) at 18 years of age. Conclusions This is the first prospective study to demonstrate that body dissatisfaction in adolescence predicts the occurrence of later depressive episodes in a cohort born in the early 1990s. The findings highlight that body dissatisfaction is a public health concern.

ObjectiveTo determine the risk of death due to prominent mental disorders, substance abuse, and self-harm among US Olympians compared with the general population.MethodsAll female (n=2301) and male (n=5823) US Olympians who participated in the summer or winter Games between 1912 and 2012 were followed until 2016. The National Death Index certified their vital statuses and causes of death. We performed a Standard Mortality Ratio (SMR) analysis for all causes studied and applied the years-saved (YS) method to quantify differences in the risk of death for (1) anxiety, depression and self-harm and (2) substance abuse and eating disorders. Additionally, we examined the YS across sports with greater than 100 total deaths and between medalists and non-medalists.ResultsUS Olympians had a 32% (SMR=0.68, 95% CI 0.49 to 0.91) lower risk of death compared with the general population, resulting in a longevity advantage of 0.21 YS (95% CI 0.14 to 0.29) for deaths by depression, anxiety and self-harm and 0.12 years (95% CI 0.08 to 0.15) for substance abuse and eating disorders. There were no significant differences between medalists and non-medalists, but findings varied by sports. Most sports (eg, athletics, swimming, rowing) had significantly lower risks of deaths than the general population with the exceptions of fencing and shooting. Shooting showed a trend towards a higher risk through suicide by firearm.ConclusionOlympians have a lower risk of death, favouring an increased longevity compared with the general population for mental disorders, substance abuse and suicides.

BackgroundDespite increases in cannabis use generally and for pain management, data regarding cannabis use in patients undergoing surgery are lacking. This study examined the prevalence of cannabis use among patients undergoing elective surgery and explored differences in clinical characteristics and surgical outcomes between cannabis users and non-cannabis users.MethodsThis prospective study included 1335 adults undergoing elective surgery. Participants completed self-report questionnaires preoperative and at 3-month and 6-month postsurgery to assess clinical characteristics and surgical outcomes.ResultsOverall, 5.9% (n=79) of patients reported cannabis use (53.2% medical, 19.0% recreational and 25.3% medical and recreational). On the day of surgery, cannabis users reported worse pain, more centralized pain symptoms, greater functional impairment, higher fatigue, greater sleep disturbances and more symptoms of anxiety and depression versus non-cannabis users (all pConclusionsCannabis use is relatively low in this surgical population, yet cannabis users have higher clinical pain, poorer scores on quality of life indicators, and higher opioid use before and after surgery. Cannabis users reported similar surgical outcomes, suggesting that cannabis use did not impede recovery.

ObjectivesTo investigate SARS-CoV-2 (the virus causing COVID-19) infection and exposure risks among grocery retail workers, and to investigate their mental health state during the pandemic.MethodsThis cross-sectional study was conducted in May 2020 in a single grocery retail store in Massachusetts, USA. We assessed workers’ personal/occupational history and perception of COVID-19 by questionnaire. The health outcomes were measured by nasopharyngeal SARS-CoV-2 reverse transcriptase PCR (RT-PCR) results, General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9).ResultsAmong 104 workers tested, 21 (20%) had positive viral assays. Seventy-six per cent positive cases were asymptomatic. Employees with direct customer exposure had an odds of 5.1 (95% CI 1.1 to 24.8) being tested positive for SARS-CoV-2 after adjustments. As to mental health, the prevalence of anxiety and depression (ie, GAD-7 score >4 or PHQ-9 score >4) was 24% and 8%, respectively. After adjusting for potential confounders, those able to practice social distancing consistently at work had odds of 0.3 (95% CI 0.1 to 0.9) and 0.2 (95% CI 0.03 to 0.99) screening positive for anxiety and depression, respectively. Workers commuting by foot, bike or private cars were less likely to screen positive for depression (OR 0.1, 95% CI 0.02 to 0.7).ConclusionsIn this single store sample, we found a considerable asymptomatic SARS-CoV-2 infection rate among grocery workers. Employees with direct customer exposure were five times more likely to test positive for SARS-CoV-2. Those able to practice social distancing consistently at work had significantly lower risk of anxiety or depression.

AimsThe presence of detectable faecal haemoglobin (f-Hb) has been shown to be associated with all-cause mortality and with death from a number of chronic diseases not known to cause gastrointestinal blood loss. This effect is independent of taking medicines that increase the risk of bleeding. To further investigate the association of f-Hb with chronic disease, the relationship between f-Hb and prescription of medicines for a variety of conditions was studied.MethodsAll subjects (134 192) who participated in guaiac faecal occult blood test (gFOBT) screening in Tayside, Scotland, between March 2000 and March 2016, were studied in a cross-sectional manner by linking their gFOBT result (abnormal or normal) with prescribing data at the time of the test.ResultsThe screening participants with an abnormal gFOBT result were more likely to have been being prescribed medicines for heart disease, hypertension, diabetes and depression than those with a normal test result. This association persisted after adjustment for sex, age and deprivation (OR 1.35 (95%CI 1.23 to 1.48), 1.39 (1.27 to 1.52), 1.35 (1.15 to 1.58), 1.36 (1.16 to 1.59), all pConclusionsThe results of this study confer further substantial weight to the concept that detectable f-Hb is associated with a range of common chronic conditions that have a systemic inflammatory component; we speculate that f-Hb might have potential in identifying individuals who are high risk of developing chronic conditions or are at an early stage of disease.

Background and aimThe purpose of this study was to evaluate the health-related quality of life (HRQOL) of patients with multiple sclerosis (MS) globally to provide precise information for policy makers to take necessary steps to improve the quality of life of these patients. This systematic review and meta-analysis is the first global study in the last decade.Materials and methodsData from January 2000 to April 2020 were collected from Scopus, PubMed, Embase, Web of Science and Google Scholar databases on the basis of inclusion and exclusion criteria. Data obtained were analysed by R software, and 54 articles were finally included in the study.ResultsFrom the 2126 articles collected, a total of 54 articles were included in the study. Based on the results of random-effects analysis (DerSimonian and Laird), the mental HRQOL score was 55.18 (95% CI 52.71 to 57.65) and the physical HRQOL score was 48.72 (95% CI 45.93 to 51.52). In this study, age and duration of disease had a significant and direct relationship with mental HRQOL (p≤0.01). Moreover, mental HRQOL was higher in Europe than in other continents, while physical HRQOL was higher in Asia than in other continents. HRQOL was also evaluated on the basis of three valid questionnaires: Short Form 36, Multiple Sclerosis Quality of Life-54 and Multiple Sclerosis International Quality of Life.ConclusionAccording to the results of this study, the total score for HRQOL indicates moderate quality of life. Factors such as depression, age and duration of disease have the greatest impact on HRQOL, whereas factors such as fatigue and the Expanded Disability Status Scale score have less effects on HRQOL, so that patients with MS continue their daily activities as long as they are physically able to, and this happens despite disease progression.

Learning objectives In 1964, Glaser recognised that, ‘Despite benefits derived from these remarkable therapeutic gains, children with congenital heart disease face many difficulties in their efforts toward social and emotional adjustment.’1 In 1981, Doucet wrote, ‘The impact of congenital heart disease on the individual would not be limited to the physiological alteration in the heart’s functioning but would affect the whole individual.’2 Recognition of the broader lifestyle implications of congenital heart disease (CHD) for both children and adults is thus not a modern concept. However, what is unique to the current era of CHD care in developed countries is that over 90% of infants born with CHD survive to adulthood, with the number of adults living with CHD now far surpassing the number of children.3 This demands that we expand our definition of successful adult CHD (ACHD) outcomes to include good quality of life, including the best possible neurocognitive and psychosocial functioning, and target our clinical efforts accordingly. Although neurocognitive and psychosocial outcomes among adults with CHD are often considered independently, this silo-oriented approach ignores their reciprocal interplay. For example, neurocognitive, academic and occupational functioning can be adversely affected if a person is struggling with anxiety or depression. Similarly, neuropsychological deficits can adversely affect social development, impairing one’s ability to establish and sustain satisfying relationships in adulthood. In addition, one cannot fully appreciate adult outcomes without considering their origins in childhood and adolescence. In this review, we thus apply a developmental lifespan perspective to better understand neurocognitive and psychosocial outcomes of …

BackgroundDepression and vitamin D deficiency are common in patients with lung cancer and have prognostic implications in cancer settings. However, their relationship and concomitant survival implications have not been evaluated in patients with metastatic lung cancer specifically. We hypothesised that vitamin D deficiency would be associated with depression and inferior cancer-related survival in patients receiving therapies for stage IV lung cancer.MethodsThis was a cross-sectional analysis of vitamin D, depression and lung cancer characteristics. Vitamin D levels were stratified by level (no deficiency ≥30 units, mild deficiency 20 to 29 units and moderate-to-severe ResultsVitamin D deficiency was evident in almost half of the sample (n=98) and was associated with significant depression (HADS-D ≥8) (χ2=4.35, pConclusionVitamin D deficiency is associated with depression in patients with metastatic lung cancer. Depression modulates the survival implications of vitamin D deficiency in this population. The role of vitamin D deficiency in cancer-related depression warrants further investigation since both are amenable to treatment. Psychological and nutritional prognostic considerations may help inform treatment paradigms that enhance quality of life and survival.

Background and objectivesChronic pain affects many adults. To improve our daily practice, we need to understand multidisciplinary approaches, integrated treatment plans and the biopsychosocial context of these patients. To date, almost 15 000 chronic pain patients have been referred to the Maastricht University Pain Center in the Netherlands.MethodsThis study describes 11 214 of these patients suffering from chronic pain. Chronic pain was analyzed using relevant Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials instruments.ResultsMost patients were female (59.3%). The prevalence of low education was 59%, and unemployment/disability was 35.9%. The mean age was 55.6 years. Severe pain (Numerical Rating Sale score 7–10) was reported by 71.9% of the patients; psychological and quality of life values deteriorated when pain severity increased. Approximately 36% of patients showed severe signs of depression or anxiety, and 39% displayed high pain catastrophizing. Of all patients, 17.8% reported high values for pain severity, catastrophizing and anxiety or depression.ConclusionsBased on baseline biopsychosocial values, this study shows the complexity of patients referred to pain centers. Pain management with a biopsychosocial approach in an integrated multidisciplinary setting is indispensable. Above all, adjusted education on chronic pain and attention to its biopsychosocial aspects are deemed necessary.

While the acute effects of concussion and mild traumatic brain injury (TBI) are well understood, the certainty in the medical literature regarding the long-term outcomes of sports-related concussion is limited. Long-term deficits that may result from single, repeated concussions, and possibly subconcussive impacts, include cognitive dysfunction, depression and executive dysfunction. Perhaps most troublingly, repetitive head impacts have been linked to neurodegenerative diseases, including chronic traumatic encephalopathy (CTE), although the precise risk of long-term consequences remains unknown. CTE represents a distinct tauopathy with an unknown incidence in athletic populations; however, a cause and effect relationship has not yet been demonstrated between CTE and concussions or between CTE and exposure to contact sports, as no prospective longitudinal studies have been performed to address that question. Studies of high-school sports exposure and long-term outcomes have not demonstrated consistent findings.Medical advice regarding return to play and the risk of acute and/or long-term consequences is therefore problematic. It is important that the individual’s right to make their own choices regarding their health is respected. Team, coach, parental, peer or financial pressures should not influence this decision. The choice to return to play after a concussion or mild TBI injury is the athlete’s decision once they have (1) recovered from their injury and have the legal capacity to make an informed decision; (2) been medically assessed and (3) been informed of any possible long-term risks in a language that they can understand.Given the current lack of certainty in relation to long-term outcomes from concussion, is it possible to provide a framework to inform players of current evidence, as part of a consent process, even if the information upon which the decision to return to sport is based remains uncertain and evolving?

BackgroundThe endovascular treatment (ET) for acute ischemic stroke is increasing among eligible patients. Assessing patients’ perspectives on quality of life (QOL) can supplement the use of formal outcome scales and enable the assessment of outcomes across multiple domains affected by stroke.MethodsWe analyzed publicly available data from the Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke (DEFUSE 3) trial. We evaluated patients who survived beyond the time of discharge from their acute hospitalizations and completed all Neuro-QOL short forms at 90-day follow-up.ResultsOur final analysis included 128 patients (median age 67 [range 23–90] years, 50.8% men). As modified Rankin Scale (mRS) scores increased, there was a consistent increase in the severity of Neuro-QOL measures. T-scores for mobility, cognitive function, and the ability to participate in social roles declined significantly while depression T-scores increased significantly. We found that QOL T-scores for patients with mRS 3 did not differ significantly from T-scores for patients with mRS 2 in any domain.ConclusionsAmong ischemic stroke patients eligible for ET, QOL scores help validate and supplement quantitatively measured outcomes.

IntroductionDepression and harmful alcohol consumption contribute significantly to the global health burden, but in young adults, this relationship is under-researched and conflicted. The aim of this study was to determine the sex-based prevalence and the association between internalising disorders such as depression and alcohol use disorders.MethodUsing the Avon Longitudinal Study of Parents and Children, we assessed the sex-specific prevalence of International Classification of Diseases,Tenth Revision diagnosed generalised anxiety disorder (GAD), depression and fear-based anxieties (FBA) at 24 years (n=3572). We examined the association between internalising disorders and alcohol consumption using the Alcohol Use Disorder Identification Test for Consumption 5+ threshold and Diagnostic and Statistical Manual on Mental Disorders defined criteria for alcohol dependence.ResultsWomen reported more GAD (11.6% vs 6.5%), depression (13.4% vs 6.9%) and FBA (1.3% vs 0.5%) than men (pConclusionsYoung adults in the UK who drink harmfully are more likely to have depression and other internalising disorders. Further research should test whether there is a J-shaped relationship between alcohol consumption and mental health in young people and whether this varies across the life course.

Background Research suggests that genetic predisposition for common mental disorders may be moderated by the environment. This study examines whether a polygenic risk score (PRS) for depression is moderated by the level of residential area urbanicity using five symptoms of poor mental health as outcomes. Methods The study sample consisted of 41 198 participants from the 2006–2008 wave of the Norwegian HUNT study. We created a weighted PRS for depression based on 99 variants identified in a recent genome -wide association study. Participants were classified into urban or rural place of residence based on wards that correspond to neighbourhoods. Mixed effects logistic regression models with participants nested in 477 neighbourhoods were specified. Results A SD increase in PRS for depression was associated with a small but statistically significant increase in the odds of anxiety, comorbid anxiety and depression and mental distress. Associations for depression were weaker and not statistically significant. Compared with urban residents, rural resident had higher odds for reporting poor mental health. Genetic propensity for depression was higher for residents of urban than rural areas, suggesting gene–environment correlation. There was no sign of effect modification between genetic propensity and urbanicity for depression, anxiety, comorbid anxiety and depression, or mental distress. Conclusion The PRS predicted small but significant odds of anxiety, comorbid anxiety and depression and mental distress, but we found no support for a differential effect of genetic propensity in urban and rural neighbourhoods for any of the outcomes.

BackgroundSubstantial uncertainty exists about the prevalence of depression in patients with gastric cancer. We aimed to summarise the global and regional pooled prevalence of depression among patients with gastric cancer.MethodUp to February 2020, we searched PubMed/MEDLINE, Embase, Scopus, Web of science (ISI) and PsychINFO to identify published studies on the prevalence of depression among patients with gastric cancer. The study selection procedure was in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We estimated the prevalence of depression in gastric cancer patients using a random-effect pooled estimate analysis approach with subgroup analysis based on WHO regions, and methods of depression measurement.ResultsTotally, we retrieved 3781 studies from the previously mentioned databases, of which 18 (12 cross-sectional and 6 cohort studies in design) met the eligibility criteria, which were published from 2001 to 2017 in different regions. The total sample size of the included studied contained 4709 patients with gastric cancer, of which 1885 cases were diagnosed with depression. The pooled prevalence of depression among gastric cancer patients was 37%(95% CI: 26% to 48%). Subgroup analysis showed that the highest prevalence of depression was in Eastern Mediterranean (pooled prevalence=42%; 95% CI: 18% to 65%) followed by the Western Pacific region (pooled prevalence=40%;95% CI: 26% to 54%). The results indicated a significant heterogeneity (I2=98.8%,PConclusionOur findings indicated that depression is high among gastric cancer patients. The findings suggest health authorities to provide specially designed social and psychological supportive care services, including screening for depression, among such patients.PROSPERO registration numberCRD42020139836.

ObjectiveTo examine how different aspects of social relationships are associated with incident cardiovascular events and all-cause mortality.MethodsIn 4139 participants from the population-based Heinz Nixdorf Recall study without previous cardiovascular disease (mean (SD) age 59.1 (7.7) years, 46.7% men), the association of self-reported instrumental, emotional and financial support and social integration at baseline with incident fatal and non-fatal cardiovascular events and all-cause mortality during 13.4-year follow-up was assessed in five different multivariable Cox proportional hazards regression models: minimally adjusted model (adjusting for age, sex, social integration or social support, respectively); biological model (minimally adjusted+systolic blood pressure, low-density and high-density lipoprotein cholesterol, glycated haemoglobin, body mass index, antihypertensive medication, lipid-lowering medication and antidiabetic medication); health behaviour model (minimally adjusted+alcohol consumption, smoking and physical activity); socioeconomic model (minimally adjusted+income, education and employment); and depression model (minimally adjusted+depression, antidepressants and anxiolytics).Results339 cardiovascular events and 530 deaths occurred during follow-up. Lack of financial support was associated with an increased cardiovascular event risk (minimally adjusted HR=1.30(95% CI 1.01 to 1.67)). Lack of social integration (social isolation) was associated with increased mortality (minimally adjusted HR=1.47 (95% CI 1.09 to 1.97)). Effect estimates did not decrease to a relevant extent in any regression model.ConclusionsPerceiving a lack of financial support is associated with a higher cardiovascular event incidence, and being socially isolated is associated with increased all-cause mortality. Future studies should investigate how persons with deficient social relationships could benefit from targeted interventions.

There are important dissimilarities in clinical presentation, aggregation of comorbidities, cardiovascular risk factors and the quality of delivery of medical care among men and women with acute coronary syndrome (ACS). Compared with men, despite the well-known older age and more pronounced frailty, women with ACS present later from symptom onset and are at high bleeding risk after invasive procedures. In addition, autoimmune/inflammatory disease, fibromuscular dysplasia, polycystic ovary, early menopause and history of pre-eclampsia are risk factors preceding ACS among younger women. They more often experience myocardial infarction in the absence of obstructive coronary arteries (MINOCA), which makes diagnosis and treatment of ACS among women more challenging compared with men. Women and men do both benefit from guideline-recommended treatment, although, compared with men, women with ACS have a higher adjusted risk of early death, which equalises between both sexes within the first year. Young women with ACS suffer frequently of depression and present often with MINOCA. Compared with young men, they (young women) have a higher risk of death. Therefore, focusing on young patients with ACS, understanding the particular physiopathology of MINOCA and developing programmes targeting comorbidities and depression-related behavioural risk factors are urgently needed.

IntroductionImproving the mental health of young people is a global public health priority. In Latin America, young people living in deprived urban areas face various risk factors for mental distress. However, most either do not develop mental distress in the form of depression and anxiety, or recover within a year without treatment from mental health services. This research programme seeks to identify the personal and social resources that help young people to prevent and recover from mental distress.Methods and analysisA cross-sectional study will compare personal and social resources used by 1020 young people (aged 15–16 and 20–24 years) with symptoms of depression and/or anxiety and 1020 without. A longitudinal cohort study will follow-up young people with mental distress after 6 months and 1 year and compare resource use in those who do and do not recover. An experience sampling method study will intensively assess activities, experiences and mental distress in subgroups over short time periods. Finally, we will develop case studies highlighting existing initiatives that effectively support young people to prevent and recover from mental distress. The analysis will assess differences between young people with and without distress at baseline using t-tests and χ2 tests. Within the groups with mental distress, multivariate logistic regression analyses using a random effects model will assess the relationship between predictor variables and recovery.Ethics and disseminationEthics approvals are received from Ethics Committee in Biomedical Research, Faculty of Medicine, University of Buenos Aires; Faculty of Medicine-Research and Ethics Committee of the Pontificia Universidad Javeriana, Bogotá; Institutional Ethics Committee of Research of the Universidad Peruana Cayetano Heredia and Queen Mary Ethics of Research Committee. Dissemination will include arts-based methods and target different audiences such as national stakeholders, researchers from different disciplines and the general public.Trial registration numberISRCTN72241383.

ObjectiveGeographic atrophy (GA), a type of dry age-related macular degeneration, affects vision as central vision loss (CVL). The challenges faced due to bilateral CVL in activities of daily living and strategies taken to overcome those challenges are not very well understood in the Indian population. This qualitative study aims to understand the impact on everyday life activities and related adaptive and coping strategies in people with long-standing bilateral CVL due to GA in India.Design, participants, setting and methodsA qualitative study using a semistructured face-to-face interview was conducted on 10 people with bilateral CVL after obtaining written informed consent. The interviews were audio-recorded, and were transcribed verbatim. Thematic analysis was carried out to understand the challenges faced and adaptive methods due to the impact of CVL.ResultsTen participants (50% male) with a median age (IQR) of 72 (70, 74) years were interviewed. All the participants had best-corrected visual acuity of ≤6/60 in the better eye and reported an absolute central scotoma with the home Amsler chart. Qualitative thematic analysis identified four main themes: challenges in everyday living (difficulty in face identification, reading), challenges with lifestyle and socialisation (driving, cooking, reading for a longer duration, watching TV, socially inactive), psychological implications (depression, poor self-esteem, fear due to poor vision) and strategies to overcome the challenges (voice identification, technology support).ConclusionGA has a severe negative impact on the quality of life in people with CVL. Inability to recognise faces was the main reason for dependency on others and being socially disconnected. The findings will help clinicians in providing improved rehabilitative care.

The outbreak of COVID-19 poses an unprecedented threat and a great challenge to health workers (HWs) in Wuhan, China.1 The situation of women HWs in Wuhan is even more difficult. According to 2019 Chinese Health Statistics Yearbook, the number of women HWs in China accounted for 71.8% of Chinese HWs, far exceeding that of men HWs. Women HWs has become the major force to tackle the COVID-19 epidemic. Owing to entrenched traditional social roles in China, women HWs are placed at a considerable dilemma of how to balance work and family care. Previous studies have also suggested that women were vulnerable to mental health problems.2 The mental health problems of women HWs may affect their attention and decision-making ability and could have a lasting effect on their overall well-being. Hence, psychological impact of COVID-19 on women HWs in Wuhan should be pronounced. Tongji Hospital, one of the biggest hospitals in Wuhan, was officially designated as ‘the specific hospital for the treatment of severe patients with COVID-19’, with a women HWs proportion of 81.0%. This hospital has opened 2000 beds specifically for patients with severe COVID-19, and women HWs from all clinic departments of this hospital are sent to the frontline of COVID-19. Given the high infectivity of the COVID-19, the hospital administrators arranged lodging support for the frontline HWs living apart from their families. A cross-sectional study was designed to evaluate the immediate psychological impact on women HWs of Tongji Hospital, determine the predictors of acute stress, depression and anxiety symptoms and investigate the sources of acute stress among the women HWs. ### Study design and participants The study was a cross-sectional, single-centre survey, covering doctors, nurses and medical technicians in all clinical departments of Tongji Hospital. The study was conducted between 8 February and 15 February 2020, …

ObjectiveIn a paediatric chronic pain population, to determine whether higher body mass was associated with poorer functioning, mood or treatment outcome.DesignCross-sectional study with examination of treatment outcomes.SettingTertiary specialist adolescent pain rehabilitation unit.Patients355 adolescents with relatively severe non-malignant chronic pain.InterventionsIntensive 3-week pain rehabilitation programme.Main outcome measuresObjective physical measures (walk, sit-to-stand); self-reported functioning and moodResultsAverage body mass index (BMI) in the sample was relatively high (24.2 (SD 5.6)) with 20.5% being classified as obese. However, there were no relationships between body mass and objective physical measures, physical or social functioning, depression or anxiety (all p>0.05). There was a small relationship between higher body mass and greater pain-related fear (r=0.17, pConclusionsHigher body mass does not worsen functioning, mood or treatment response in adolescents with disabling chronic pain. Childhood obesity and chronic pain are both stigmatised conditions; clinicians should avoid implying that high body mass alone is a causal factor in the struggles of a young person with chronic pain.

BackgroundThere is evidence in the literature that parents of children who have a developmental disability experience an increased risk of mental health problems.MethodsThis study used population-level administrative data from the Ministry of Health, British Columbia, Canada, to assess the mental health of parents of children who have a developmental disability compared with the mental health of parents of children who do not have a developmental disability. Population-level and individual explanatory variables available in the data were included in the models.ResultsAt a population level, the study found strong evidence that parents of children who have a developmental disability experience higher odds of depression or other mental health diagnoses compared with parents of children who do not have a developmental disability. Age of the parent at birth of the child, income and location of healthcare services were all associated with outcomes.ConclusionParents of children who have a developmental disability may be in need of programmes and services that support their mental health.

ObjectivesStudies indicate women aged 25–49 years previously treated for cancer report cognitive alterations. Good evidence indicates physical activity can be beneficial after cancer and might additionally benefit cognitive function. This short report presents data from a substudy of the Younger Women’s Wellness after Cancer Program (YWWACP), which explored cognitive alterations and investigated potential associations between physical activity and cognitive function in participants in the YWWACP. The primary aim of this substudy was to determine in younger women previously treated for breast cancer (1) whether subjectively reported cognitive function changed over time and (2) if physical activity is associated with subjectively reported cognitive function, and if time had an impact on this.MethodsAll participants had completed breast cancer treatment. Data were collected at baseline (n=41) and at 12 weeks. Measures assessed demographics, self-reported physical activity, cognitive function, sleep quality, stress, anxiety and depression using validated and reliable, subjectively reported instruments.ResultsCognitive function and physical activity scores increased across the time points, with cognitive function revealing a statistically significant increase over time (p=0.004). Statistical testing revealed that physical activity was not correlated with cognitive function and that change in physical activity was not correlated with change in cognitive function.ConclusionThese data provide early evidence that cognitive function and physical activity improved over time in this sample. However, interpretations of a correlation between physical activity and cognitive function should be made with caution, and future research would benefit from larger samples.

BackgroundDepressed patients often focus on negative life events. Effective antidepressant therapy reverses this negative emotional bias (NEB) within 1 week. Clinical therapeutic effect usually requires 4–6 weeks. The value of implementing NEB monitoring for the personalisation of antidepressant therapy is unknown.ObjectiveTo estimate the likely outcome and cost consequences of adopting the P1vital Oxford Emotional Test Battery (ETB) for this purpose in routine primary care in England.MethodsA hybrid decision analytic model (decision tree plus Markov model) was developed to estimate the cost-effectiveness of ETB monitoring versus no ETB over 52 weeks using quality-adjusted life years (QALYs). Differences in depression severity, episode type and analytical perspectives were considered. Input data were derived from relevant guidelines, literature, national databases, expert opinion and the developers for the year 2013. Multiple sensitivity analyses addressed uncertainty.FindingsThe mean number of ETB tests is 2.162 per newly diagnosed patient and 2.166 per patient with recurrent depression. The incremental cost-effectiveness of ETB versus ‘no ETB’ is £4355/QALY from the healthcare perspective. From the broader societal perspective, ETB is more effective and cost saving.ConclusionsMonitoring negative emotional bias in primary care in England for personalised antidepressant treatment using ETB seems as an effective and cost-effective option under all considered scenarios (including worst case). Its main economic value seems to lie in reduced productivity loss as opposed to healthcare savings.Clinical implicationsThe test supports accelerated application of evidence-based depression care. Further optimisation and implementation in the ongoing European PReDicT trial is ongoing.

BackgroundArthroplasty is one of the most commonly performed procedures in the USA with projections of continuous growth. As this field undergoes continuous changes, the goal of this study was to provide an analysis of patient-related and healthcare system-related trends. This is important as it allows practitioners, administrators and policy makers to allocate needed resources appropriately.MethodsThe study included total knee arthroplasty (TKA) and total hip arthroplasty (THA) procedures from 2006 to 2016. Demographic information, comorbidities and complications were extracted and analyzed from the Premier Healthcare database.ResultsThe surgical volume increased annually over the observation period by an average of 5.54% for TKA and 7.02% for THA, respectively. The average age of the patient population and the types of anesthesia used remained relatively consistent over time. Comorbidity burden increased, especially for obesity (16.52% in 2006 and 29.77% in 2016 for TKA, 11.15% in 2006 and 20.92% in 2016 for THA), obstructive sleep apnea (OSA) (6.82% in 2006 and 17.03% in 2016 for TKA, 4.69% in 2006 and 12.72% in 2016 for THA) and renal insufficiency (2.81% in 2006 and 7.01% in 2016 for TKA, 2.78% in 2006 and 6.43% in 2016 for THA). Minor trends of increases were also observed in the prevalence of liver disease, depression and hypothyroidism. All postoperative complications were trending lower except for acute renal failure, where an increase was noted (4.39% in 2006 and 8.10% in 2016 for TKA, 4.99% in 2006 and 8.42% in 2016 for THA).DiscussionSignificant trends in the care of patients who undergo TKA and THA were identified. Individuals undergoing these procedures presented with a higher prevalence of comorbidities. Despite these trajectories, complications declined over time. These data can be used to inform future research and to allocate resources to address changes in populations cared for and complications encountered.

ObjectiveMetabolic syndrome (MetS) includes hyperglycaemia, hypertension, central adiposity, elevated triglyceride levels and low levels of high-density lipoprotein cholesterol. All factors are identified as risk factors for cardiovascular disease and mortality. This longitudinal study examined whether loneliness, which has been shown to predict a range of negative health outcomes, increases the risk for MetS.MethodsWe used data from ‘the Nord-Trøndelag Health Study’ (HUNT) which is a large longitudinal health study based on a Mid-Norway county population (n=26 990). Self-reports, physical examinations and blood samples were analysed to evaluate the associations between loneliness and incidents of MetS after 10 years (follow-up survey conducted during 2006–2008). We also investigated the role of depression as a potential mediating factor.ResultsIndividuals who reported higher levels of loneliness had a higher odds for MetS (adjusted OR 1.09 (95% CI 1.02 to 1.16); p=0.007). This effect was mediated through depression.ConclusionsFindings suggest that loneliness may be an important factor that increases the risk for MetS. The effect of loneliness on MetS is mediated through depressive symptoms. Reducing loneliness may help prevent the incidence of MetS and related diseases.
