To determine whether a biopsychosocial model of suicidality, specifically sleep, nutrition, physical exercise, mindfulness, social connectedness, lower socioeconomic status (SES) and sex are uniquely associated with increased suicidal ideation, longitudinally over adolescence.

Longitudinal, prospective cohort study.

A structured self-report questionnaire was collected as part of the Longitudinal Adolescent Brain Study at the University of the Sunshine Coast’s Thompson Institute (Queensland, Australia) from July 2018 to January 2024.

159 Australian adolescents (n=91 female; 68 male) aged 12 to 17 years.

Self-reported suicidal ideation was measured longitudinally. Data were also collected on self-reported lifestyle factors (sleep, nutrition, physical exercise, mindfulness and social connectedness), psychological distress, SES and sex. All measures were collected at 4-monthly intervals for each participant for up to 5 years (maximum of 15 time points).

Significant relationships were identified between increased suicidal ideation and poor sleep (OR 2.6, 95% CI 1.4 to 4.6, p=0.002), socioeconomic disadvantage (SES quintile 1: OR 6.3, 95% CI, 1.8 to 21.8, p=0.004; SES quintile 2: OR 8.7, 95% CI 1.4 to 56.2, p=0.022), psychological distress (OR 5.7, 95% CI 2.1 to 15.6, p≤0.001) and eating habits (β –0.08, 95% CI –0.2 to –0.0).

Poor sleep, socioeconomic disadvantage, psychological distress and eating habits were all found to be significantly associated with increased adolescent suicidal ideation over time. These biopsychosocial factors should be considered in targeted interventions and policies for reducing adolescent suicidality. Further research should employ multilevel modelling to examine factor interactions and rigorously evaluate interventions targeting lifestyle factors and socioeconomic inequalities through randomised controlled trials and quasi-experimental designs.

To analyse demographic trends and decision-making patterns regarding prenatal diagnosis (PND) in couples at risk for hereditary haemoglobinopathies at the Thalassemia and Rare Haematological Disease Centre in Turin over a 40-year period.

Retrospective observational study analysing demographic and clinical data from 1983 to 2023.

Tertiary care genetic service Centre in Orbassano (TO), Northern Italy.

Couples seeking genetic counselling and PND for hereditary haemoglobinopathies. Selection criteria included couples at risk of having children affected by β-thalassaemia major or Sickle Cell Disease (SCD).

Primary outcomes included acceptance rates of PND and pregnancy termination (TOP). Variables analysed included couples’ age at first consultation, age at first PND, birthplace, employment status, specific haemoglobinopathy risk and number of pregnancies.

The analysis identified three main factors influencing PND and TOP decisions: nationality, type of haemoglobinopathy risk and number of previous pregnancies. Age showed no significant correlation with decision-making patterns. The impact of education level and employment status could not be definitively determined due to unavailable or unfit data.

The 40-year analysis of prenatal diagnosis for haemoglobinopathies in Turin shows evolving trends influenced by immigration patterns, improved medical treatments and cultural factors, leading to increased acceptance of affected pregnancies in recent years, particularly after 2015, due to better disease management and comprehensive healthcare support. This comprehensive analysis of our centre’s experience provides valuable insights that can serve as a model for similar institutions worldwide in supporting couples through carrier screening and PND processes.

Functional constipation (FC) is prevalent among children and often persists despite standard pharmacological treatment with oral laxatives. Many parents turn to complementary therapies, including acupuncture, which has been shown to relieve symptoms in adults with FC. However, studies in children with FC are scarce and have important limitations. This study will evaluate the feasibility, safety and potential efficacy of acupuncture for children with FC.

Prospective, non-randomised, open-label pilot study in children with FC (6–18 years). Participants will undergo eight acupuncture sessions over 10 weeks. Concurrent pharmacological treatment with polyethylene glycol (≥0.2 g/kg/day) will continue as initiated prior to enrolment. The primary endpoint is feasibility, defined by an attrition rate of ≥70%. Secondary feasibility endpoints include consent rate, patient/parent satisfaction and personnel requirements. Safety will be assessed by systematic monitoring of adverse events. Efficacy endpoints include treatment success, defined as no longer meeting the Rome IV criteria for FC at the end of the intervention period, as well as defecation frequency, stool consistency, painful defecation, faecal incontinence frequency, abdominal pain, medication use and quality of life, based on a previously published core outcome set.

Ethical approval was provided by the Medical Ethics Committee of Amsterdam UMC (Netherlands; NL87083.018.24). Results will be published in peer-reviewed journals and presented to scientific and consumer audiences.

Community health workers (CHWs) are critical to healthcare delivery in low-resource settings but often lack formal clinical training, limiting their decision-making. Large language models (LLMs) could provide real-time, context-specific support to improve referrals and management plans. This study aims to evaluate the potential utility of LLMs in assisting CHW decision-making in Rwanda.

This is a prospective, observational study conducted in Nyabihu and Musanze districts, Rwanda. Audio recordings of CHW-patient consultations will be transcribed and analysed by an LLM to generate referral decisions, differential diagnoses and management plans. These outputs, alongside CHW decisions, will be evaluated against a clinical expert panel’s consensus. The primary outcome is the appropriateness of referral decisions. Secondary outcomes include diagnostic accuracy, management plan quality, and patient and user perceptions to ambient recording of consultations. Sample size is set at 800 consultations (400 per district), powered to detect a 15–20 percentage point improvement in referral appropriateness.

Ethical approval has been obtained from the Rwandan National Ethics Committee (RNEC) (Ref number: RNEC 853/2025) in June 2025, recruitment started in July 2025 and results are expected in late 2025. Results will be disseminated via stakeholder meetings, academic conferences and peer-reviewed publication.

As the opioid crisis continues, people who use drugs (PWUD) experience a disproportionate burden of both HIV and overdose, driven by increased injection-related HIV outbreaks and an opaque and rapidly evolving drug market, respectively. Pre-exposure prophylaxis (PrEP) for HIV and point-of-care drug checking services are underused yet potentially impactful interventions to address the harms of the opioid crisis. Implementing such interventions using known strategies to enhance client engagement and reduce access barriers, such as street outreach, mobile services and peer navigation, can optimise intervention and maximise their impact.

The Substance Checking Outreach and PrEP Engagement (SCOPE) Study is a non-randomised clinical trial evaluating the impact of the Check It intervention, a mobile community PrEP and drug checking intervention in Baltimore, Maryland, USA. SCOPE will recruit a cohort of 500 PWUD at risk for HIV through street-based recruitment methods. Cohort members will be followed semi-annually for 18 months. The primary study outcomes are engagement with the PrEP continuum of care and the number of non-fatal overdoses. We will use both random effects models and marginal structural models to estimate the effects of Check It on participant engagement on the PrEP continuum and the number of non-fatal overdoses over time.

Study procedures have been approved by the Johns Hopkins Bloomberg School of Public Health Institutional Review Board. Risks to participants are low, with the most serious risk being potential data confidentiality breaches. This risk was minimised through the use of secure data storage platforms with limited user access. Study findings will be disseminated through peer-reviewed manuscripts, academic presentations, and reports and fact sheets designed for lay audiences.

This study was registered with clinicaltrials.gov (study ID: NCT05977881; Protocol ID: 00017498).
