Early screening for autism spectrum disorder (ASD) can enhance educational and health outcomes for affected children. This narrative systematic review explores school-based screening tools used around the world to identify children with ASD and explore the differences across socio-demographic groups.

Systematic review of electronic databases (EMBASE, MEDLINE, PsycINFO, Cochrane and Scopus) in October 2024 of papers published between 2011 and 2024.

Mainstream school-based settings globally.

Children aged 4–16 years old attending mainstream school.

School-based screening tools for ASD, including all types of informant and format of tools reported in eligible studies.

Primary outcomes included prevalence of screen positives, sensitivity and specificity of the screening tools. Secondary outcomes included participants’ sex, socioeconomic status and ethnicity, and the relation of this to the primary outcomes.

Of 7765 eligible articles, 14 studies were included in this review. We identified eight different school-based ASD screening tools. Study populations ranged from 103 to 16 556 children, with sensitivity and specificity varying by screening tool used, age group, setting and ASD prevalence. The percentage of children screening positive for ASD ranged from 0.7% to 8.5%. Studies were conducted in Europe (n=6), Western Pacific (n=4), the Americas (n=3) and Eastern Mediterranean (n=1) regions. No studies explicitly explored accuracy or validity outcomes based on ethnicity or socioeconomic status. Half of the 14 studies (n=7) reported the sensitivity and specificity of the screening tools; sensitivity ranged from 58% to 94% and specificity from 61% to 100%. There was insufficient evidence to recommend any single ASD screening tool.

ASD screening tools vary widely across the globe, with limited standardisation. Evidence is lacking on how ethnicity and socioeconomic status affect their effectiveness in schools. Given the dearth of scientific evidence in this field, collaboration among educators, researchers and policymakers is needed to establish the evidence base for universal screening, identify optimal tools, coordinate their use and ensure their validation for specific populations.

Strengthening research capacity in Africa is vital for tackling pressing health, educational and socioeconomic challenges facing the continent. At the core of this effort is the cultivation of innovative research leaders through postgraduate training programmes that incorporate mentorship-infused supervision. Such models have demonstrated potential in improving research skills, boosting academic productivity and fostering leadership development among emerging scholars. This systematic review and meta-synthesis protocol aims to examine existing mentorship-infused supervision practices across African higher education institutions. The review seeks to identify effective models, uncover common challenges and barriers, and generate evidence-based recommendations to develop sustainable, contextually relevant strategies. Insights from this work will inform policies and practices to enhance postgraduate research training, advance research leadership and contribute to the broader goal of strengthening research ecosystems across Africa.

A systematic review and thematic meta-synthesis will be undertaken, focusing on qualitative research studies as well as the qualitative components of mixed-methods studies. Relevant studies published in English will be identified through a comprehensive search strategy. The electronic databases, including Medline/PubMed, Scopus, Web of Science, African Journals Online, EMBASE and CINAHL, will be searched to capture a wide range of peer-reviewed articles and grey literature. Databases will be searched from March 2026. Two reviewers will independently perform study selection, data extraction, quality assessment and evaluation of risk of bias, using the Critical Appraisal Skills Programme checklist.

This systematic review and meta-synthesis will analyse publicly available literature and does not require ethical approval, as it involves no primary data collection. It will adhere to established ethical and methodological standards, including proper citation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The findings will be widely disseminated through open-access journal publication, conference presentations and targeted reports for universities, research institutions and policymakers to inform and support mentorship-based postgraduate research supervision across Africa.

Establishing comparability between measured outcomes in clinical trials poses a significant obstacle for systematic reviewers. Core outcome sets (COSs) were developed to address this issue. The macular degeneration (MD) COS is designed to standardise outcome measurement across clinical trials for MD. This study investigates the uptake of the MD COS in standardising outcome measurement across clinical trials.

Cross-sectional analysis

We conducted a search on ClinicalTrials.gov to locate MD clinical trials that were registered 5 years prior to COS publication through the search date of 26 June 2023 and obtained a pool of 2152 registered studies. After applying various inclusion and exclusion criteria, we analysed 159 trials. We then analysed the COS uptake using an interrupted time series analysis (ITSA) and performed performed analyses of variance (ANOVAs) and Pearson correlations to evaluate associations between trial characteristics and outcome measurement.

ITSA showed no significant change in uptake following the MD COS (2016): mean percentage of completion of the COS increased by 0.24% per month before publication (p=0.27) and by 0.07% per month after publication (p=0.62), indicating no meaningful post-publication slope change in COS use. For context, visual acuity was most commonly measured, while several patient-reported and disutility domains were infrequently captured.

No discernible patterns in COS usage for MD trials were observed. We recommend further collaboration between regulators and COS developers to help with COS uptake. Additionally, we suggest that further studies analyse adherence to COSs in respect to regulatory recommendations.

To estimate the sociodemographic and geographical variation in prescribing selective serotonin reuptake inhibitors (SSRIs) and medications for attention-deficit/hyperactivity disorder (ADHD) to children and young people (CYP) in North West London, UK.

Cross-sectional population-based study.

General practices in North West London, UK, with data for the period 2020–2022 obtained from the Discover Now platform, which covers approximately 95% of the local population.

762 390 CYP aged 5–24 years in the year 2022.

Primary outcome: Prescription rates of SSRIs and ADHD medications. Secondary outcomes: Associations between prescription rates and sociodemographic factors, including age, gender, geographical area (local authority), ethnicity and socioeconomic deprivation (measured using the Index of Multiple Deprivation).

The total sample comprised 762 390 CYP. 2.20% of the sample were prescribed an SSRI (95% CI 2.17% to 2.24%) and 0.50% an ADHD medication (95% CI 0.49% to 0.52%) in years 2020–2022. High deprivation was associated with the highest rates of an SSRI prescription (2.5%). In contrast, low deprivation was associated with the highest rates of an ADHD medication prescription (0.70%). This divergent pattern was evident in some London boroughs and not in others. The relationship between level of area deprivation and prescription rates also differed by borough. Overall, the sociodemographic factors could not explain most of the variation in prescription rates (Pseudo R² 0.18 for SSRI and 0.06 for an ADHD medication).

Prescriptions for common mental disorders and ADHD for CYP from North West London varied by sociodemographic characteristics and London borough of residence, potentially exacerbating mental health inequalities. To monitor and address these inequalities, more extensive use of linked electronic health records should be undertaken; for example, data on mental health diagnosis and service utilisation are needed to investigate the relationship between diagnosis and treatment over time.

This study aimed to identify the determinants of severe acute malnutrition (SAM) relapse among children aged 6–59 months.

Case-control study.

Selected public health facilities in Gode city and district, Somali region, Eastern Ethiopia, from April 1–30, 2024.

394 (131 cases and 262 controls) children aged 6–59 who were treated for SAM and discharged.

387 (129 cases and 258 controls) participated, resulting in an overall response rate of 98.2%. A logistic regression model with an OR of 95% CI was used to estimate the strength of the association, and a p value

The mean age of mothers/caretakers for cases and controls was 30.0 (±6.9) and 29.2 (±6.2) years, respectively, with over half (51.9% cases and 54.3% controls) falling in the 25–34 age range. Significantly associated factors with SAM relapse were food-insecure households (adjusted (AOR)=2.26; 95% CI 1.39 to 3.65), poor hand-washing practices (AOR=3.11; 95% CI 1.90 to 5.08), duration of treatment stay

This study shows the important determinant factors associated with SAM relapse among 6–59-month-old children after discharge from outpatient therapeutic programmes in Godey City and district in Eastern Ethiopia. The significantly associated factors, including household food insecurity, inadequate hand-washing practices, shorter treatment duration, low MUAC at discharge and lack of vitamin A supplementation, indicate the multifaceted nature of this public health problem.

Enhancing household food security through community-based programmes, promoting health education on proper hand washing and hygiene practices, extension of outpatient treatment duration to prevent premature discharge, ensuring that MUAC threshold for discharge is properly attained, and integrating postdischarge Vitamin A supplementation into primary healthcare services.

Eating disorders are complex mental health conditions characterised by pathological behaviours related to food intake, often accompanied by a chronic obsession with weight control. Their prevalence is increasing, with an earlier onset and greater severity among young people. Universal prevention, through multicomponent strategies that tackle modifiable risk factors, has emerged as a promising tool. This paper reports the study protocol designed to assess the effectiveness and cost-effectiveness of the PRETA (Prevención de los Trastornos de la Alimentación) programme in reducing the risk of eating disorders and related modifiable risk factors among preadolescents in the school setting.

The PRETA programme will be assessed by means of an open, community-based, multicentre, controlled trial using 1:1 matched-pairs cluster randomisation at the school level. Schools in Tenerife (Spain) will be assigned to the PRETA programme or a waitlist control group. Participants include 5th- or 6th-grade students (10–13 years old), their parents and teachers. The PRETA programme is a universal, school-based, multicomponent programme designed to reduce eating-disorder risk and modifiable risk factors. Its main component is an interactive online platform called e-PRETA, complemented by training sessions for families and teachers. e-PRETA includes nine 45-minute sessions addressing risk factors, such as dietary habits, beauty standards, media literacy, self-esteem, emotional regulation and social skills. A total of 1068 children from 12 schools will participate. The primary outcome will be the risk of developing eating disorders (Children’s Eating Attitudes Test-26 item version). Secondary outcome measures are body dissatisfaction (Adapted Contour Drawing Rating Scale), eating disorder traits (Eating Disorder Inventory-2), internalisation of appearance ideals (Sociocultural Attitudes Towards Appearance Questionnaire-4) and self-esteem (Rosenberg Self-Esteem Scale). Outcomes will be assessed at baseline and postintervention (3 months). Additional baseline covariates such as electronic device use, parental feeding attitudes, physical activity, sleep duration and screen time will also be collected. Programme effectiveness will be analysed using generalised mixed models. Cost-effectiveness will be assessed by comparing the incremental costs associated with the implementation of the PRETA programme with its estimated effectiveness.

Ethics approval has been obtained from the Ethics Committee for Research with Medicines at the University Hospital of the Canary Islands (CHUC_2021_78). Written informed consent will be obtained from the parents or legal guardians of all participants. Results will be disseminated through scientific publications and conferences.

Hospital falls persist as a major threat to patient safety. This study aimed to develop an interprofessional reference standard to prevent, manage and report hospital falls.

A Delphi consensus methodology, informed by the Conducting and Reporting Delphi Studies guideline, was used to design the reference standard. An interprofessional expert panel (n=47) of health professionals, researchers, policymakers and consumers participated in three Delphi rounds. Following the review of clinical guidelines, an e-Delphi survey was developed and piloted to derive 60 initial items for the standard. Two iterative rounds of e-Delphi surveys were distributed via Research Electronic Data Capture and included free-text questions and 9-point Likert scales. An online consensus meeting followed, to ratify the final standard.

In the first Delphi round, there was over 80% agreement for 44/60 items to be included in the reference standard. This increased to 48/60 items in Round 2. At the final consensus meeting, 12 items still did not reach consensus for inclusion and one was added, yielding 49 items. Items that replicated text according to falls with injury/without injury were combined, resulting in 42 items in the final reference standard. Agreed items included: (1) brief screening of falls risk on hospital admission; (2) comprehensive falls assessment for inpatients who are older, frailer or have complex conditions; (3) single interventions (such as environmental adaptations and exercise); (4) multifactorial interventions; (5) education of patients, families and staff; (6) optimising local falls hospital policies, procedures and leadership capability; (7) optimising documentation and reporting; (8) improving accreditation processes; (9) workforce redesign to augment falls education. Items that did not reach agreement (n=12) pertained to alarms, bed rails, grip socks, artificial intelligence, volunteers and care bundles.

This new reference standard provides a checklist for staff, patients, managers and policymakers to reduce unwanted variations in prevention, management and reporting of hospital falls.

Suicide is a leading cause of preventable death worldwide. Evidence supports the impact of providing active contact for individuals who have attempted suicide. The current systematic review and meta-analyses aim to investigate the effects of suicide prevention strategies implemented through remote and synchronous technology-based interventions.

Systematic review, narrative synthesis and meta-analysis.

Electronic databases (PubMed, PsycINFO, Scopus and Web of Science) and grey literature sources (ClinicalTrials.gov and Google Scholar) were searched until December 2024.

Eligible articles assessed suicide prevention interventions for participants over 12 years with prior suicidal behaviour. Eligible study designs included randomised controlled trials and non-randomised clinical trials published in English or Spanish.

Screening, selection process, data extraction and risk of bias assessment were performed independently by two reviewers. Data on suicide-related factors and adherence to treatment were extracted. Meta-analyses were conducted to determine effect sizes (Hedges’ g) for suicidal ideation, risk ratios (RR) for suicide attempts and Peto odds ratios (OR) for suicide. Heterogeneity was assessed using the Cochrane’s Q test, tau² statistic and I² value. Publication bias was investigated employing funnel plots and Egger’s test.

A total of 28 studies, comprising 10 015 participants in the intervention group and 10 726 in the comparison group, were included in the systematic review and meta-analyses. Synchronous remote-based interventions were effective in preventing repeated suicide attempts at 1 month (RR 0.73, 95% CI 0.62 to 0.85, I²=0.0%, Q=0.70, tau²=0.00), 6 months (RR 0.56, 95% CI 0.34 to 0.95, I²=85.4%, Q=54.92, tau²=0.36) and 12 months (RR 0.68, 95% CI 0.49 to 0.96, I²=87.6%, Q=72.63, tau²=0.27). Additionally, these interventions were associated with a reduction in suicide-related deaths at 18 months (Peto OR 0.18, 95% CI 0.08 to 0.44, I²=0.0%, Q=0.03, tau²=0.00). Effects on suicidal ideation were not statistically significant at any time point (Hedges’ g –0.07 to –0.28, I²=0.0 to 69.3%, Q=1.16 to 7.38, tau²=0.00 to 0.14).

Synchronous remote-based interventions demonstrate a potential benefit in preventing suicide attempts and deaths by suicide and may serve as an adjunct to usual treatment; however, the effect on suicidal ideation appears limited. The observed heterogeneity warrants caution when interpreting these findings. Future research should prioritise methodological enhancements to improve the quality and consistency of evidence, as well as investigate the mediating processes underlying their effectiveness in reducing suicidal behaviour.

Suicide is a leading cause of death in the USA, and its incidence has increased substantially in recent years. Observational studies have used large, linked databases to investigate risk factors for suicide, but data generally originate from a small number of similar sources. Prevention efforts may be strengthened by linking data from diverse sources across multiple sectors. The New Opportunities for Health and Resilience Measures for Suicide Prevention project aims to develop a resource for characterising key risk and protective factors for suicide outcomes by linking state-level death records with county-level data from 12 administrative sources, including medical, legal and social service records, among others.

Administrative records of death, emergency medical services, emergency department syndromic surveillance, homelessness services, psychiatric crisis services, jail stays, domestic violence referrals and Medicaid/Medicare claims will be obtained through partnerships with source agencies. Death records are available for Washington State, while all other records are available for residents of King County, Washington. Temporal availability varies, but records generally cover the years 2014 to 2023. An iterative machine learning paradigm will be used to link individuals across different records, and events will be harmonised and deduplicated.

This study has been approved by the Washington State Institutional Review Board, and data sharing agreements have been established with each contributing data source. Descriptive information will be disseminated via public data dashboards of suicide and non-fatal suicide behaviours. Analytic studies will be disseminated in peer-reviewed scientific journal publications.

To assess the impact of opening a large community-based asynchronous review ophthalmic clinic on attendance delays among patients with stable chronic eye disease attending a London teaching eye hospital network.

Interrupted time-series analysis of routine electronic health records of appointment attendances.

A large eye hospital network with facilities across London, UK, between June 2018 and April 2023.

We analysed 69 257 attendances from 39 357 patients, with glaucoma and medical retina accounting for 62% (n=42 982) and 38% (n=26 275) of visits, respectively. Patients over 65 made up 54% (n=37 824) of attendances, while 53% (n=37 014) were from the more deprived half of the population, and 51% (n=35 048) were males.

An asynchronous review clinic opened in a shopping centre in London, in autumn 2021, following the COVID-19 lockdown in spring 2020.

Average attendance delays (days), calculated as the difference between follow-up attendance date and the latest clinically appropriate date determined at the preceding attendance.

Pre-COVID-19, attendance delays for chronic eye disease monitoring were increasing by 0.9 days per week (95% CI, 0.8 to 0.9) on average, worsening to 2.0 days per week (95% CI, 2.0 to 2.0) after the first COVID-19 national lockdown, mid-March 2020. Opening the asynchronous review clinic increased appointment capacity, with delays decreasing on average by 8.1 days per week (95% CI, 8.1 to 8.2) shortly after opening. The rate of decrease slowed to 0.3 days per week (95% CI, 0.3 to 0.3) after 5 months. We found no significant differences in average attendance delays by age, gender or level of deprivation.

The asynchronous review clinic significantly reduced attendance delays across the hospital network, addressing pre-existing backlog for stable chronic eye diseases. The reduction appeared to be maintained after the initial backlog had been cleared.

Variations in mental health and sexual and reproductive health (SRH) outcomes of girls/women (cisgender and transgender) and gender-diverse (nonbinary, Two-Spirit, gender fluid, agender, queer, gender neutral) youth with intersectional identities exist and have largely been ignored in the literature. There is a lack of information on how these health services meet the health needs of girls/women and gender-diverse youth with intersectional identities and the quality of such services. The objective of this global realist review is to identify how, why, for whom, in what contexts and to what extent mental health and SRH services meet the health needs of girls/women (cisgender and transgender) and gender-diverse youth (10–25 years) with intersectional identities.

The protocol has been registered with PROSPERO and will follow Realist and Meta-narrative Evidence Syntheses Quality Standards for Realist Reviews. We will identify the programme theory and implementation determinants of mental health and SRH services for girls/women (cisgender and transgender) and gender-diverse (nonbinary, Two-Spirit, fluid, agender, queer, gender neutral) youth (10–25 years). The scope of the review will be defined in the first stage and will include consultations with youth Advisory Group members and initial programme theory development. An iterative search of scholarly bibliographic databases (MEDLINE, Embase, APA PsycInfo, CINAHL, Web of Science, IBSS) in addition to a grey literature search will take place in the second stage. The third stage will include evidence extraction and synthesis. In the final stage, the narrative will be developed and refined in consultation with Youth Advisory Group members, and findings will be disseminated.

The study was approved by the Research Ethics Board at the Centre for Addiction and Mental Health (2023/153). Findings will be disseminated through peer-reviewed publications, youth-friendly materials and webinars and national and international conferences.

For several decades, mortality has decreased more rapidly among individuals with a higher socioeconomic position than among those with a lower position. This widening social inequality gap has increasingly been recognised as an important aspect of public health research and policies. The objective of this study was to examine trends in educational inequality in healthy life expectancy (HLE) in Denmark between 2010 and 2021 at the age of 30 years.

The study is a population-based study based on register data on longest attained education, standard life tables and self-reported health information from nationwide health surveys.

The study is conducted among the general adult population in Denmark.

Participants include respondents from the Danish National Health Survey and the Danish Health and Morbidity Survey in 2010, 2013, 2017 and 2021 aged ≥30 years.

Expected lifetime in good self-rated health, with no long-standing illness and with no activity limitations was estimated by Sullivan’s method, and educational inequality was expressed by the Slope Index of Inequality.

Between 2010 and 2021, educational inequality in HLE increased among both men and women for long-standing illness (5-year trend: +1.1 and +1.2 years) and activity limitations (+2.4 and +2.6 years) but remained stable among men (+0.1 year) and decreased among women (–0.3 year) for self-rated health. For the latter two indicators, the inequality gap narrowed after 2017.

Trends in educational inequality in HLE in Denmark 2010–2021 vary by health indicator. Steadily widening gaps were demonstrated for long-standing illness, while narrowing gaps were seen after 2017 for activity limitations and self-rated health. Future studies are encouraged to explore potential health risk behaviours that may explain or modify these inequality trends.
