Epidemiology and Psychiatric Sciences

The COVID-19 pandemic had substantial impact on healthcare systems across the globe, including psychiatric services. Use of electroconvulsive therapy (ECT), a lifesaving intervention for severe mental illness, was reported to have declined during the pandemic in several countries, but nationwide data remain scarce. Using nationwide data from the Danish National Patient Register, we examined all ECT treatments administered in Denmark from September 2019 to May 2025. Weekly treatment numbers were visualized across the three national COVID-19 lockdowns to descriptively assess changes in ECT use. A notable reduction in ECT treatments was observed in the weeks preceding and during the first lockdown (March 11 to May 18, 2020). A post-hoc estimation indicated approximately 1,366 "missed" treatments during the initial pandemic phase in 2020. When these were added to the 27,033 treatments delivered in 2020, the adjusted total approximated annual treatment volumes in 2019 and 2022, suggesting a temporary disruption rather than sustained decline. In contrast, ECT activity during the second and third lockdowns appeared largely unaffected. These findings suggest that ECT provision in Denmark was temporarily reduced during the initial phase of the pandemic but remained resilient thereafter. In the case of a future pandemic, safeguarding timely access to ECT--particularly in early phases-- should be prioritized given its critical role in the treatment of severe mental illness.

BackgroundIn 2020, Oregon became the first U.S. state to establish a regulated framework for adults to access psilocybin services using naturally-derived mushroom products. No studies have examined mental health outcomes among individuals receiving psilocybin in this context. AimsTo evaluate changes in self-reported symptoms of depression, anxiety, and well-being 30-days post-psilocybin session under the Oregon state-regulated model , and document session-related adverse events and doses consumed. MethodsThis was a naturalistic study (March 2024-April 2025) among adults [&ge;]21 years participating in a legal psilocybin services program. Online surveys were completed pre-session, 1-day, and 30-days post-session. Primary outcomes were change in depression, anxiety, and well-being symptoms pre-session to 30-days post-session evaluated using linear mixed-effects models (random effect: timepoint; fixed effects: sex, concurrent psychiatric medication use, age, session dose [total psilocybin equivalents, TPE, mg: psilocybin mg + 1.39 * psilocin mg]). Adverse events (e.g., hallucinogen persisting perception disorder [HPPD]) were assessed at 1-day and 30-days post-session. ResultsParticipants (n=88; median age 43 years; 52% male) were predominantly Oregon residents (53.4%), psychedelic-experienced (64.8%), and concurrently using psychiatric medication (46.6%). All outcomes improved significantly at 30-days post-session (p<0.001), including in sensitivity analyses stratified by concurrent psychiatric medication usage (p<0.001 all outcomes, both groups). Two participants (2.3%) reported symptoms consistent with HPPD at 1-day post-session, but none at 30-days. Mean dose was 27.8 mg (SD 8.2) TPE. ConclusionsPsilocybin sessions delivered under the Oregon regulatory model were associated with clinically meaningful improvements in depression, anxiety, and well-being 30-days post-session, supporting therapeutic effectiveness of legal psilocybin services.

ObjectiveAlthough trauma-focused psychotherapies are effective for posttraumatic stress disorder (PTSD), recovery under routine outpatient conditions remains variable. We examined whether participation in a structured Specialty Care (SC) model integrating clinician specialization, flexible treatment density, and coordinated navigation was associated with accelerated PTSD recovery compared with standard outpatient care. MethodsWe conducted a retrospective matched cohort study (2024-2025) of U.S. adults with active PTSD symptoms (PTSD Checklist for DSM-5 score [&ge;]31) receiving care through an employer-sponsored digital mental health platform. Access to SC was determined by employer benefit design. Propensity-score matching with weighting balanced cohorts on baseline severity and demographics. Primary outcomes included longitudinal PTSD symptom trajectories and time to recovery, remission, and reliable improvement. Secondary outcomes assessed depressive symptoms (PHQ-9). Linear mixed-effects and Cox proportional hazards models were applied. ResultsThe matched sample included 356 SC and 9,409 standard care participants. SC participants received higher treatment intensity, including greater session volume and faster early follow-up, and greater care navigation engagement. SC participation was associated with steeper PTSD symptom decline ({beta} = -1.3 per log-week, p < .001) and a higher likelihood of recovery (hazard ratio = 1.31; 95% CI, 1.10-1.57). At 12 weeks, predicted recovery was 29% in SC versus 23% in standard care. Depressive symptoms improved in both groups, without significant differences in time to categorical recovery. ConclusionsUnder routine outpatient conditions, a structured SC model was associated with accelerated PTSD recovery, suggesting that reorganization of outpatient delivery may improve real-world outcomes.

IntroductionNational trends in youth suicide risk may mask significant regional variations within a country. This article attempts to account for spatio-temporal trends through a comparative analysis across South America and Europe. This paper analyzes the spatiotemporal patterns in suicide mortality among young people (10-29 years) in Argentina, Chile, Spain, and Uruguay during the period 1997-2021. MethodsOfficial data from vital statistics and population censuses of the four countries were analyzed. Spatiotemporal clusters were detected using Poisson-based scan statistics. Sociodemographic characteristics of high-and low-mortality clusters were compared with the rest of each country using Kruskal-Wallis and Wilcoxon tests. ResultsWith the exception of Chile, each country showed the emergence of spatiotemporal suicide clusters extending through 2021. Indicators of social fragmentation and lower socioeconomic status were most consistently associated with the formation of high-risk youth suicide clusters. ConclusionRecent national increases in youth suicide rates appear to be concentrated in specific sub-national regions, underscoring the need to target resources toward improving living conditions and mental healthcare access for young people in these areas.

BackgroundUp to one-third of medical inpatients experience clinically relevant mental distress, yet many remain untreated. Stepped and collaborative care (SCC) models may improve access to mental health care, but predictors of service uptake are unclear. We examined patient- and ward-level predictors of psychosomatic-psychiatric consultation (PPC). MethodsWe analyzed data from SomPsyNet, a stepped-wedge cluster randomized trial targeting SOMatic inpatients across three Swiss tertiary hospitals, to prevent PSYchosocial distress by a care NETwork. Analyses focused on inpatients screening positive for mental distress. Multiple-imputed logistic regressions assessed predictors of four sequential service-use stages: PPC considered, offered, accepted, and received. ResultsAmong 589 distressed patients, 93.9% were offered PPC, 63.1% accepted, and 83.9% of acceptors received PPC, yielding a 50% overall receipt rate. Patients without Swiss citizenship showed higher odds of acceptance (odds ratio [OR]=1.82 [1.10, 3.00]) and eventual receipt (OR=1.62 [1.01, 2.62]). Being in a Geriatric ward facilitated PCC uptake, while patients from gynecology showed reduced progression through the care pathway. Age, gender, income, education, marital status, and living arrangement showed no statistically robust associations. ConclusionsAlmost two-thirds of mentally distressed medical hospital inpatients accepted an offered PPC, indicating high acceptability. About half ultimately received a consultation, highlighting substantial attrition along the SCC pathway. Ward specialty and nationality were key determinants of PPC uptake. These findings suggest that proactive, ward-oriented consultation-liaison models embedded in routine inpatient care may improve timely and equitable access to mental healthcare, including for migrant and minority patients who are otherwise less likely to access such care. HighlightsO_LIPsychosomatic-psychiatric consultation pathway of medically hospitalized inpatients C_LIO_LI63% accepted such a consultation when offered; overall 50% reached receipt.

ObjectivesElectroconvulsive Therapy (ECT) is an effective treatment for bipolar disorder, particularly in severe acute cases or for illness resistant to pharmacotherapy. However, the risk of relapse following ECT is high, necessitating intervention to reduce this risk. Based on findings from ECT studies in unipolar depression and its well-known mood-stabilizing properties, it is likely that lithium treatment may reduce the risk of relapse of bipolar disorder following ECT. Therefore, we conducted a target trial emulation using data from Danish nationwide registers to investigate whether lithium protects against relapse following ECT treatment of bipolar disorder. MethodsPatients discharged from their first psychiatric admission with a primary diagnosis of bipolar disorder between January 1, 2006, and June 1, 2024, who received at least six ECT treatments, were included. Follow-up began two weeks after discharge and continued until relapse, death, one year, or January 1, 2025. Patients were considered allocated to lithium treatment if they redeemed a prescription for lithium within the first two weeks after discharge from the index admission (ECT treatment). The outcome was time to relapse, defined by either psychiatric hospital admission or suicide. Cox proportional hazards regression, adjusted for potential confounders, was used to compare the outcome between patients allocated and not allocated to lithium treatment. ResultsAmong the 574 eligible patients (mean age 41.5 years, 61.3% women), 214 (37.3%) were allocated to lithium treatment and 360 (62.7%) were not allocated to lithium treatment. During follow-up, 56 patients (26.2%) in the lithium group and 135 patients (37.5%) in the non-lithium group experienced a relapse. Lithium treatment was associated with a substantially reduced risk of relapse (adjusted hazard rate ratio, 0.60, 95% CI=0.43-0.84). ConclusionLithium treatment after ECT may reduce the risk of relapse in patients with bipolar disorder. These findings should be followed up by a randomized controlled trial.

Background At present, there are no approved pharmacological treatments for people at clinical high risk for psychosis (CHR-P). We sought to assess the acceptability of cannabidiol (CBD): a promising candidate treatment for this population. Methods CHR-P individuals completed a survey which assessed their views on the acceptability of CBD, its expected effectiveness and side effects, and on formulation preferences. Results The sample comprised 55 CHR-P individuals (24.3 years and 69% female). Most (91%) were familiar with CBD, and had previously used cannabis (64%), and around half (42%) had tried over-the-counter CBD. 75% were willing to take CBD as an intervention for mental health problems. Most participants anticipated fewer side effects with CBD than with existing medications, and preferred tablet or capsule formulations over liquids. Discussion CBD is perceived as a highly acceptable treatment among CHR-P individuals.

Background and HypothesisClozapine is the only antipsychotic with protective effects against suicide in schizophrenia (SCZ). Newer third-generation antipsychotics (TGA) have better tolerability and modulate serotonin, dopamine, and N-methyl-d-aspartate neurotransmission pathways implicated in suicide. We aimed to investigate the effects of TGAs on suicide in SCZ. MethodsWe searched seven databases up to December 2023 for SCZ studies that reported suicide data. The primary outcome was suicide deaths and attempts; suicidal ideation was added as a secondary outcome. Random effects meta-analyses quantified suicide risk in randomized controlled trials (RCT) while single proportion meta-analyses assessed longitudinal suicide risk in open label extension trials (OLE). For RCTs, sensitivity analyses were conducted and subgroup analyses explored the impact of dose, drug type, and comparator arm. Study ResultsTwenty articles were included; thirteen excluded higher suicide risk participants. Compared to placebo control, TGAs did not significantly change the risk of primary [RR = 0.65, p = 0.38] or secondary [RR = 0.63, p = 0.15] suicide outcomes. Subgroup and sensitivity analyses were not statistically significant. For OLEs, there was a significant increase in the incidence of primary [Ip = 0.004, p = 0.048] and secondary [Ip = 0.024, p = 0.0013] suicide outcomes, but there was marked study heterogeneity. ConclusionThere is no current trial evidence to show that TGAs significantly impact suicide outcomes in SCZ. The signal from OLEs should be interpreted cautiously due to heterogeneity and requires replication. An effective clozapine alternative is needed for suicide prevention in SCZ.

IntroductionSevere mental illness is associated with high mortality rates and cardiovascular disease. Obesity and dysmetabolism associated with antipsychotic treatment comprise modifiable risk factors, which remain undertreated. Interventions such as antipsychotic-switching, lifestyle-interventions and weight-reducing medication have shown varying results indicating a need for a more individualized approach. The Meta-Care Trial aims to assess the effectiveness of a pragmatic, individualized, evidence- and guideline-based cardiometabolic intervention. Methods and analysisMeta-Care is an open-label randomized controlled trial (RCT). Patients between 18-45 years with schizophrenia spectrum disorders or bipolar disorder will be recruited from in- and outpatient Mental Health Services in the Capital Region of Denmark. Inclusion criteria include treatment with antipsychotics and: either i) [&ge;]5% body weight gain or [&ge;]5cm waist circumference increase since initiation of antipsychotic therapy, or ii) a body mass index (BMI) [&ge;]30 kg/m2, or iii) BMI [&ge;]27 kg/m2 and related cardiovascular risk factors. Patients are randomized to a pragmatic, individualized metabolic clinic using evidence- and guideline-based care in a mental health center or standard care. Allocation-ratio is 1:1. The primary outcome is the proportion of patients achieving weight loss [&ge;]5% of initial body weight after 12 months. Secondary and exploratory outcomes cover cardiometabolic risk factors, cognition, personal recovery, and quality of life. Qualitative interviews will explore patient experience and contextual factors. Recruitment started in October 2023 and will include a total of 84 patients. Ethics and disseminationThe Meta-Care trial is funded by The Independent Research Fund Denmark and The Worzner Memorial Fund for Research in Mental Illness. The trial has been approved by the Regional Ethics Committee and Data Protection Agency in the Capital Region of Denmark. Positive, negative, and inconclusive results will be published in scientific peer-reviewed journals, presented at conferences, and dispersed to patient organisations and media. Strengths and limitations- The Meta-Care Trial is the first randomized control trial (RCT) to investigate the effectiveness and acceptability of a pragmatic, individualized metabolic clinic located in a mental health center using evidence- and guideline-based care to treat obesity and cardiometabolic risk factors in patients with severe mental illness - The pragmatic design with limited exclusion criteria and simple outcome measures will generate results that are generalizable to clinical practice - The complex Meta-Care multi-intervention limits inferences of effects explained by specific modifications of pharmacotherapy or lifestyle changes - Potential knowledge exchange from treating personnel in the Meta-Care Trial to caregivers in the standard care group may lead to contamination bias - Although the Meta-Care trial has an open label design, measurements of primary and secondary outcomes will be carried out by blinded assessors

BackgroundDespite widespread recognition of the value of lived experience (LE) involvement in healthcare research and increased LE involvement activity, we lack established implementation methods and instruments for reporting and evaluating impact. We present a protocol for an innovative LE-led Impact Log tool and co-production framework, which may help to address some fundamental barriers to co-production. The Impact Log will be implemented within a five-year multidisciplinary transdiagnostic research project on severe mental illness, the Brain and Genomics Hub of the UKRI Mental Health Platform, and is also designed for wider adaptation and use. Part I presents a short narrative review of literature pertaining to defining, evaluating, and enhancing the impact of co-production, to provide in-depth background and aid future development. Part II presents the Impact Log protocol. MethodsThe Impact Log framework is designed to integrate inclusive and impactful co-production throughout all research stages, and to record and evaluate its impact across three domains using an accessible short form. The three research domains are: design and delivery; interpersonal and environmental aspects; systems and processes. Impact Log design and implementation is led by LE study leads and a specialist advisory panel, who are integrated fully within the wider research team, and all have combined research experience and LE of bipolar or psychotic disorders. All Hub research participants will be offered accessible opportunities for remunerated lived experience input, and there will be outreach to ensure diverse representation, aided by the Hubs charity partners. Data collection and analysis will be LE led and will include iterative analysis to inform continuing development. Diverse formal and informal dissemination throughout the project will maximise wider stakeholder engagement. DiscussionThe potential value of this research is to implement a novel tool and framework for facilitating, recording and evaluating co-production in complex mental health research, which can be adapted for wider use. Strengths in design are LE leadership and cross-cutting LE research integration, incorporation of multiple domains, and a focus on facilitating diversity and inclusion within co-production. Potential limitations for this project and wider adaptation may include limited resources, risk of bias and health challenges. Lay SummaryWe have provided a brief lay summary to help people without a research background understand our project. This article explains our plan to develop and test a new way of understanding how research changes when people with personal experience of a mental health condition are part of the research team. We are a team of mental health researchers and many of us have direct experience of bipolar and psychosis. We work alongside other researchers, including people who might also have worked in mental health services or in charities that provide support. Our research project aims to better understand what is happening in the brain, body, lives and experiences of people who have bipolar and psychosis. Many people believe that research is better when it includes the views of people who have direct experience of the health condition being studied. This is called "lived experience". We have developed a structured approach to make sure that people with lived experience are meaningfully involved in our research team. We have also created a simple tool, called the Impact Log, to record when lived experience members contribute and to help us understand how their involvement influences the research. Finally, we wanted to better understand what other researchers have said about lived experience involvement. We reviewed many published academic studies and reports and brought their findings together in what is called a "narrative review". This review summarises what is already known about the difference lived experience involvement can make in research.

ObjectiveThis study aimed to identify characteristics that define population need groups with similar mental health service needs within prisons and describe the mix of services required to meet those needs. MethodsMixed methods were used, including three iterative, semi-structured focus groups, followed by an online survey, seeking information on the characteristics that define service needs, how these can identify groups of people who require mental health care in prisons and the services required by each group. Participation was sought from prison health services, prison mental health services, non-government service partners and people with a lived experience. Focus group transcripts and free text survey responses were thematically analysed. Descriptive statistics were generated for online survey responses to Likert Scales to determine the levels of agreement with survey content. ResultsThe characteristics and service needs of four distinct population groups who require mental health care in prisons were defined: indicated prevention, mild, moderate, severe and complex. These groups were delineated using characteristics including presence of a diagnosed mental illness, level of functional impairment, presence of added complexity and service response required. The required service mix varied across need groups, however service types common across all groups included assessments, psychological therapies, peer support, lifestyle interventions and carer support. ConclusionsThe identified need groups and service descriptions will contribute to the evidence required for needs-based planning of mental health care in Australian prisons. This information can be used for planning a responsive, equitable, and needs-based mental health service system within custodial environments.

IntroductionSepsis is a life-threatening ailment caused by an exaggerated immune response to infection that poses a major health problem, with increasing prevalence, high costs, and poor outcomes. Improved outcomes are seen in patients when providers follow the Surviving Sepsis Campaign recommended clinical practice guidelines for identifying and treating sepsis using a 3-hour and 6-hour bundle after sepsis is suspected. Previous research has shown patients with mental health issues receive worse quality of diabetes and cardiac care and have poorer outcomes compared with those without mental health issues. Similarly, patients with mental health issues may receive worse sepsis care due to inability to explain symptoms, agitation, etc. This study explores sepsis quality of care among patients with vs. without an acute mental health crisis, and whether patients with certain mental health issues were more likely to receive sepsis bundle care than others. MethodsUsing data extracted from 2018-2019 at the Long Island Jewish Medical Center Emergency Department (ED), patients who met sepsis inclusion criteria were grouped into either having, or not having, a severe mental illness crisis on the basis of whether physical or chemical restraints were used in the ED. Patients with a history of a severe mental illness, but who were not in a severe mental health crisis, were grouped with the patients without mental health illness, as, in the absence of an acute psychiatric problem, their mental health issue unlikely affected sepsis care. We describe demographic characteristics of both groups and performed a univariate analysis using Students T-test to compare the percent of those with vs. without acute mental health crisis who received full 3- and 6-hour sepsis bundle care. Patients with an acute mental health crisis were grouped according to "cognitive" (eg, dementia) vs. "non-cognitive" (eg, schizophrenia) disorders. ResultsComparing those with vs. without acute mental health crisis, there was no difference in the percent of patients who received 3-hour sepsis bundle care (80.7% vs 74.9%, p = 0.1456). However, among patients who received the 3-hour bundle, a significantly-greater percent of those with an acute mental health crisis received the 6-hour sepsis bundle (51.0% vs. 30.7%, p <0.0001). There was no difference between different groups of patients with mental health issues (eg, "cognitive" vs. "non-cognitive") with respect to receiving 3- or 6-hour sepsis bundle care. DiscussionSurprisingly, although there was no significant difference in likelihood to receive a 3-hour sepsis bundle among patients with vs. without an acute mental health crisis, those with an acute mental health crisis were more-likely to receive 6-hour care. We suspect this difference might be due to increased attention paid to patients with an acute mental health crisis, including more-frequent room visits by hospital staff or more concerns among family members. No particular set of mental health conditions was associated with receiving or not receiving appropriate care. Future research could address possible confounding factors, go into more detail about the specific component of the sepsis protocol that patients failed to receive, and specify what aspects of a mental health crisis affected treatment plans. Future studies are needed to assess possible associations between severe mental illness crisis, bundle care, and mortality in relation to ED, Intensive Care Unit (ICU), or hospital length-of-stay (LOS).

ObjectivesPeople impacted by the criminal-legal system face significant challenges to securing and sustaining permanent housing. This study was designed to assess housing outcomes of an integrated intervention that offered housing, medical, and behavioral health services to individuals with criminal-legal system involvement. MethodsAfter a baseline needs assessment, participants were linked to services and completed quarterly study visits for up to 12 months. We used descriptive statistics to assess frequency and multivariate logistic regression to assess correlates of being housed at last follow-up. ResultsBetween June 2019 and November 2023, 187 participants were enrolled in Project CHANGE from an area with high incarceration and overdose rates. At baseline, 43% of participants were unstably housed, 37% were homeless, and the remaining resided in a shelter or institution. At the time of last follow-up, 49 participants (26.2%) reported improved housing outcomes, and an additional 121 participants (64.7%) housing situation did not worsen. In multivariate models, individuals who were older (AOR 1.1; 95% CI 1.0-1.1), unstably housed at baseline (AOR 7.2; 95% CI 3.3-16.0), and enrolled in the study for longer (AOR 1.1; 95% CI 1.1-1.3) had higher odds of being housed at last follow-up, whereas those with high severity substance use had lower odds of being housed (AOR 0.3; 95% CI 0.1-0.6.) ConclusionsIn this comprehensive program, integrated housing/health services were time- and cost-intensive to deliver but led to positive housing outcomes. People involved in the criminal-legal system face unique barriers to housing, particularly when compounded by substance use.

ObjectiveTo analyze the structure of mental disorders in children in the outpatient practice of a specialized mental health center for optimization of care organization for this patient category. MethodsA retrospective analysis of medical records of 23 children (out of 44 patients) at the Insight Mental Health Center (Dushanbe, Tajikistan) was conducted for the period from December 9, 2025, to January 8, 2026. Diagnosis was performed according to ICD-10 criteria using standardized instruments: M-CHAT-R, ADOS-2, and ADI-R for autism spectrum disorder (ASD); SNAP-IV for attention deficit hyperactivity disorder (ADHD); CGI; and pediatric versions of PHQ and GAD. ResultsChildren accounted for 52% of all patients. Primary school-age children (7-12 years) predominated at 43.5%. Disorders of psychological development (F80-F89) dominated the nosological structure at 82.6%, with ASD comprising 56.5%. ADHD was diagnosed in 30.4% of cases. Comorbidity was registered in 47.7% of patients. ConclusionThe structure of pediatric psychiatric pathology is characterized by a predominance of developmental disorders and high comorbidity levels, justifying the need for a multidisciplinary approach.

Electronic Health Records (EHRs) have not been widely implemented in mental health settings, representing a significant gap in digital health care transformation. A reason for underutilisation includes concerns from healthcare professionals regarding the collection and storage of patients sensitive information. Language use can positively influence clinician-patient relationships, and stigmatising language in EHRs viewed by patients could undermine trust. This is concerning as using EHRs have benefits which allow patients to feel safe and empowered regarding their care. Moreover, minority ethnic groups have been found to disengage with EHRs and are more likely to access mental health services through crisis pathways. This qualitative study in collaboration with Bradford District Care NHS Foundation Trust comprises two stages to explore minority ethnic perspectives on mental health EHRs and develop recommendations for their implementation. Stage one investigates minority ethnic service users perceptions on EHRs and explores mental health professionals understanding regarding the sharing of EHRs with service users from minority ethnic groups. The workshops in stage two will use an Experience-Based Co-Design approach to produce practical recommendations for EHR implementation in mental health settings. Participants include minority ethnic service users, mental health professionals, stakeholders, and relevant bodies such as mental health organisations and Information Technology experts utilising EHRs. Data will be gathered through semi-structured interviews, focus groups and workshops, and analysed using reflexive thematic analysis. The study was approved under the Integrated Research Application System (IRAS ID: 348764) and Health Research Authority and Health and Care Research Wales. Findings will be disseminated via social media, blogs, conferences, journals, academic articles, and community and staff meetings held by the Trust. An executive summary will be shared with participants who consented to receive the results.

BackgroundSexual minority (SM) individuals have worse mental health than heterosexual peers. However, there is no total population-based and national-level evidence on differences in risk of self-harm and suicide by sexual orientation. This study provides the first national population-based estimates in England and Wales. MethodsUsing 2021 Census data linked with hospital records and death registrations, we analysed sexual orientation (SO) differences in: (i) at least one hospital inpatient admission/emergency attendance for intentional self-harm, and (ii) death by suicide. We calculated age-standardised rates per 100,000 people by SO between March 2021 and December 2023, and stratified by sociodemographic, geographical, socioeconomic and health-related variables. We calculated rate ratios for lesbian/gay/bisexual/other SO (LGB+) groups compared with heterosexuals to estimate sexual identity disparities. FindingsOur study population included 28.7 million people (mean age 48.1 years, 53.7% female, 84.2% White) aged [&ge;]16 years who self-reported their SO in Census 2021 and linked to an NHS number. LGB+ individuals had 2.52 (95% CI 2.48-2.56) times higher risk for self-harm and 2.17 (95% CI 1.98-2.37) times higher risk for suicide than heterosexual people. Relative risk of self-harm was highest for LGB+ females, younger adults, and Black individuals. Relative risk of suicide was highest for LGB+ females, older adults, and Black individuals. InterpretationThis study demonstrates stark inequalities in risk of self-harm and suicide by sexual orientation, consistent across multiple sociodemographic factors. These findings are important for informing government prevention programs and further mental health research. FundingThere was no external funding for this study. Research in contextO_ST_ABSEvidence before the studyC_ST_ABSThe substantial evidence on higher risk for self-harm and suicide in sexual minority groups in the UK (and wider Europe) is impacted by regional samples, younger populations, or surveys limited by smaller numbers precluding analyses by key sociodemographic factors (like sex, ethnic group, socioeconomic indicators, faith, housing situations and geographical indicators) or combining all sexual minority groups together. To date, no study has used total population-based data to examine sexual orientation inequalities in self-harm and suicide and in relation to a range of sociodemographic factors. Added value of this studyTo our knowledge, this is the first study in the UK to provide national population-based estimates of intentional self-harm and suicide by sexual orientation, including intersectional analyses across age, sex, ethnic group, and socioeconomic position. This study used a unique linkage between the census, hospital inpatient data, emergency care records and death registrations from across England and Wales, with a study population of 28.7 million people aged [&ge;]16 years who self-reported their sexual orientation in Census 2021 and linked to a National Health Service (NHS) number. Implications of all the available evidenceThis research provides national population-level evidence of substantial increased risk for self-harm and suicide among sexual minority individuals, compared with heterosexual individuals. This study also identified key groups of individuals at an increased risk of self-harm and suicide. These findings are important for informing government prevention programs and further research supporting the mental health of sexual minority groups.

Armed conflict in Sub-Saharan Africa has exposed millions of civilians to repeated and severe traumatic events, yet the prevalence of posttraumatic stress disorder (PTSD) and its associated determinants across the region have not been comprehensively synthesised. This study aimed to estimate the prevalence of PTSD and examine its associated factors among conflict-affected adult populations in Sub-Saharan Africa. Methodological quality was assessed using the Joanna Briggs Institute (JBI) criteria for cross-sectional and epidemiological studies A systematic search of PubMed, MEDLINE, Embase, Scopus, CINAHL, APA PsycINFO, the Cochrane Library, and the WHO Global Index Medicus (including African Index Medicus) was conducted for studies published between January 1, 2000, and May 31, 2025. Observational studies reporting PTSD prevalence among adults aged 18 years or older exposed to armed conflict were included. Study selection followed PRISMA 2020 guidelines, with independent screening by two reviewers. Random-effects meta-analyses with logit transformation were used to pool prevalence estimates, and determinants were synthesised narratively with emphasis on adjusted effect estimates. Heterogeneity was assessed using the I{superscript 2} statistic. Sixty-eight studies comprising 82,021 participants from 13 countries met inclusion criteria. The pooled prevalence of PTSD was 43% (95% CI, 35.9%-50.0%), with substantial heterogeneity (I{superscript 2} = 99.9%). Prevalence was highest among refugees (79%), followed by internally displaced persons (48%) and residents of conflict-affected communities (34%). Female sex was consistently associated with increased odds of PTSD (pooled adjusted odds ratio approximately 2.0), as were comorbid depression or depressive symptoms (AOR range 4.2-9.5). Additional correlates included cumulative trauma exposure, displacement, poor social support, and substance use. Overall, PTSD is highly prevalent among conflict-affected adults in Sub-Saharan Africa, underscoring the need for integrated, context-sensitive mental health strategies to address the enduring psychological consequences of armed conflict in the region.

Evidence-based psychotherapies are first-line treatments for psychiatric disorders, yet response rates remain suboptimal. Noninvasive brain stimulation (NIBS) may augment psychotherapy by modulating treatment-engaged circuits. We conducted a systematic review and meta-analysis of randomized controlled trials comparing active NIBS plus evidence-based psychotherapy versus sham NIBS plus psychotherapy. Following Cochrane methods, we searched six databases through February 2025, screening 1,017 records. Twenty-eight trials (31 treatment arms; 1,506 participants) met inclusion criteria. Active NIBS combined with psychotherapy produced significantly greater symptom improvement than sham NIBS with psychotherapy (standardized mean difference = -0.38, 95% confidence interval [-0.68, -0.08]), with substantial heterogeneity. Moderator analyses revealed critical implementation parameters: repetitive transcranial magnetic stimulation (rTMS) showed significant benefit while transcranial direct current stimulation did not. Non-concurrent delivery--stimulation before or after psychotherapy sessions--was significantly effective, whereas concurrent administration was not. Among psychotherapy modalities, cognitive behavioral therapy combined with NIBS produced significant benefit. Human-delivered psychotherapy, but not computerized formats, significantly enhanced outcomes. By diagnosis, significant effects were observed only for anxiety disorders. Secondary analyses revealed significant anxiety symptom reduction specific to rTMS. Treatment integrity was under-reported: only 39.3% of studies used fully manualized protocols and 10.7% documented therapist adherence. Non-concurrent rTMS paired with human-delivered, manualized cognitive behavioral therapy emerges as the most effective strategy, particularly for anxiety disorders. These findings provide an evidence-based framework for optimizing combined treatment protocols and highlight the need for standardized psychotherapy fidelity monitoring in future trials.

Objective: Posttraumatic stress disorder (PTSD) after a traumatic birth is a serious but overlooked maternal morbidity, affecting ~20% of women following medically complicated deliveries. PTSD can undermine maternal caregiving. Rapid screening tools suited to busy obstetric settings are lacking. We developed and evaluated a brief screener, derived from the 20-item PTSD Checklist for DSM-5 (PCL-5), to identify PTSD related to childbirth. Study Design: We enrolled 107 women with traumatic childbirth. Participants completed the PCL-5 and the gold-standard clinician diagnostic interview for PTSD (CAPS-5); depression was measured with the Edinburgh Postnatal Depression Scale (EPDS). Bootstrap resampling with LASSO regression identified PCL-5 items most associated with PTSD. Firth logistic regression models estimated diagnostic accuracy. Sensitivity, specificity, area under the ROC curve (AUC), and Youden's J statistic determined performance and optimal cut-off. Results: A six-item version of the PCL-5 (PCL-5 R6), statistically derived from the full scale, showed excellent discrimination for PTSD compared with clinician evaluation (AUC = 0.95; 95% CI, 0.89-1.00). A cut-off score of 7 yielded high sensitivity (0.96) and good specificity (0.83), with an overall diagnostic efficiency of 0.86, detecting most PTSD cases while minimizing false positives. The PCL-5 R6 correlated moderately with the EPDS (rho = 0.53), showing that a depression screen alone cannot reliably detect PTSD. Conclusions: A short, 6-item PCL-5 provides a valid, efficient tool for detecting childbirth PTSD. Its brevity and accuracy make it practical for integration into routine postpartum care, enabling timely mental health screening.

BackgroundThe COVID-19 pandemic, coupled with concurrent social instabilities, has raised concerns about the long-term impact on the population mental health. While existing studies have primarily focused on the acute phase, less is known about how anxiety and depression symptoms have evolved throughout prolonged societal disruption. This study aimed to identify distinct anxiety and depression symptom trajectories and to determine the individual, relational, and societal protective and risk factors that influence anxiety and depression scores among Belgian adults from 2020 to 2024. MethodsWe used longitudinal data from five waves of the COVID-19 Health Surveys and the BELHEALTH study (n = 10,063) among Belgian adults, collected between April 2020 and June 2024. Anxiety and depression were assessed using the Generalized Anxiety Disorder-7 and the Patient Health Questionnaire-9, respectively. Covariates were selected based on the social-ecological framework and included both time-invariant and time-dependent variables. Latent class linear mixed models identified subgroups with distinct trajectories. Multilevel linear mixed effects models examined associations between symptom severity and predictors across individual, relationship, and societal levels. The final model, selected based on the lowest AIC (Akaike Information Criterion), included the full set of covariates. ResultsFour depression and five anxiety trajectories were identified. While most participants maintained stable mild symptoms, 11.3% experienced increasing depression and 8.4% showed increasing anxiety over time. Financial difficulty, female gender, and younger age were overrepresented in moderate and severe symptom trajectories. Protective factors such as social support, satisfying social contact, and life satisfaction were associated with lower symptom severity. Over time, life satisfaction demonstrated an increasing protective effect, while the influence of social contact on reducing symptoms weakened progressively. Risk factors included financial and job-loss worry, loneliness, psychotropic medication use, and high mental health stigma. ConclusionsOur results demonstrate persistent heterogeneity in mental health responses, with a substantial share of the population experiencing worsening symptoms years after the pandemic began. Public mental health strategies must therefore go beyond short-term crisis response, address long-term risks such as financial insecurity, social isolation, and stigma, while fostering individual and collective resilience.
