Tobacco consumption is a significant preventable cause of death worldwide. This study aimed to assess the prevalence and associated factors of tobacco consumption among Cambodian individuals aged 15–49, utilising data from the 2021–2022 Cambodia Demographic and Health Survey (CDHS).

Cross-sectional study based on secondary analysis of the 2021–2022 CDHS.

Nationwide household survey conducted across urban and rural areas of Cambodia.

A total of 28 321 respondents aged 15–49 years were included in the analysis.

Tobacco consumption categorised as no use, smoking tobacco, smokeless tobacco and dual use. Descriptive statistics, ² tests and multinomial logistic regression were used to assess associations between background characteristics and tobacco consumption, with ‘no consumption’ as the reference category. Statistical significance was set at p

Among the 28 321 respondents (68.8% female), 91.8% were non-users of tobacco (reference group), while 6.9% reported smoking (predominantly males; adjusted relative risk ratios (ARRR)=39.29, 95% CI 29.70 to 51.96, p

While Cambodia has made notable progress in reducing tobacco consumption, the persistent challenges highlighted by the prevalence of smoking, particularly among specific demographics, indicate the need for targeted public health interventions.

To assess the association between the maternal continuum of healthcare and child immunisation in East Africa using propensity score matching (PSM).

Cross-sectional study using Demographic and Health Survey data.

This study was conducted in East African countries.

This study included a weighted sample of 13 488 women with children aged 12–23 months.

Child immunisation was the outcome variable of this study.

The PSM estimates indicate that the average treatment effect on the treated for complete child immunisation was 0.0583, meaning that children of mothers who received a complete maternal continuum of care had a 5.83% higher probability of being fully immunised compared with children of mothers with incomplete care. Expressed relative to the treated group’s mean, this corresponds to a 7.48% increase. Additionally, our results indicated that the population average treatment effect was 0.0629. This means that, on average, a complete continuum of maternal healthcare increases the probability of full child immunisation by approximately 6.29% across the entire population.

The study highlights that children whose mothers receive comprehensive maternal healthcare are more likely to complete their childhood immunisations. This finding underscores the need to integrate immunisation services into maternal healthcare programmes to enhance vaccination coverage and promote better child health. To maximise this connection, improving access to maternal healthcare, especially in underserved regions, is crucial, along with ensuring that immunisation is a regular part of maternal care.

To identify the barriers and facilitators towards deceased organ donation among Pakistanis living globally.

Systematic review using narrative synthesis.

CINAHL, Medline with Full Text, Global Health and PsycINFO via EBSCO; Scopus via Elsevier; Web of Science via Clarivate; and PubMed through the US National Library of Medicine and the National Institutes of Health were searched between 1 January 1995 and 31 July 2024 and limited to English.

We included qualitative and cross-sectional studies involving Pakistani participants aged 18 years and above, conducted both within Pakistan and internationally across settings such as universities, religious venues, hospitals and workplaces.

Four independent reviewers were involved in screening, quality assessment and data extraction. A narrative synthesis method was employed to synthesise and integrate the data from qualitative and cross-sectional studies. The Joanna Briggs Institute tool was used to assess the quality of the included studies.

Out of 11 944 studies retrieved, 26 studies were included in the current review. Based on the narrative synthesis, the findings are presented under the following five themes: (1) knowledge of deceased organ donation, (2) willingness towards deceased organ donation, (3) collective decision-making overriding individual’s preferences, (4) religious uncertainty and its impact on deceased organ donation and (5) trust and the healthcare systems.

This review shows that decisions about deceased organ donation are shaped by family dynamics, religious beliefs and trust in healthcare. More diverse research is needed to uncover new gaps and improve donor registration and consent rates in Pakistan. A whole-systems approach, considering families, religion and trust, is essential for effective strategies.

This proof-of-concept study explored the feasibility and acceptability of research cafés as a community-based model to engage racially minoritised communities in health research, with a focus on mental health.

Adopting a community peer research approach, a research team led by researchers from racially minoritised backgrounds, partnered with four voluntary organisations to conduct four research cafés. A mixed-methods feasibility design combined descriptive quantitative questionnaire data with thematic analysis of discussion notes to evaluate the impact of these cafés in South West London.

The study took place in Wandsworth, Kingston, Croydon and Sutton, in community venues provided by the voluntary organisations.

A total of 75 participants from racially minoritised backgrounds attended the sessions. Participants were intentionally selected based on age, ethnicity, location, mental well-being experiences and willingness to engage in mental health research.

Quantitative data were collected on participant attendance, demographics and feedback. Qualitative data captured participant perceptions and experiences related to healthcare and research.

The study took place between October 2023 and March 2024. Out of the 112 individuals who registered, 75 people attended with 74 contributing to the analysis (excluding one on the day sign-up). Participants were predominantly Asian/Asian British (62%) and Black/Black British (31%). All participants reported feeling comfortable and respected. Understanding of research improved for 96% and 95% expressed interest in further research involvement, most commonly the idea of joining a peer research network (64%). Participants also highlighted a need for training in research methods and communication skills for ongoing involvement. Five main themes emerged from the café discussions: (1) systemic barriers to accessing safe healthcare and mistrust of UK healthcare systems; (2) the need for cultural competence and sensitivity in healthcare and research; (3) research as a positive step for change; (4) barriers to research participation and (5) the importance of incentives and feedback for research participation.

Preliminary findings suggest that diverse and inclusive community-based partnerships are the basis for developing research cafés as a feasible and acceptable model for engaging racially minoritised communities in health research. They complement existing participatory approaches by creating inclusive, peer-facilitated spaces that build trust, improve awareness and generate high intention for future involvement and participation. Future studies are needed to test the model’s scalability across different geographic and demographic contexts and evaluate its long-term impact on research literacy, participation and equity.

This study aimed to identify and validate risk factors for suicidal ideation (SI) and non-suicidal self-injury (NSSI) among nursing staff through the development and application of a risk model and nomogram.

A cross-sectional online survey was conducted in Dehong District to collect relevant data.

A total of 1774 Chinese nursing staff members were enrolled in this study.

Multiple factors were independently associated with SI among nursing staff. These included divorce or other non-marital status (OR=2.42, 95% CI 1.07 to 5.44), drinking frequency (OR=1.34, 95% CI 1.001 to 1.79), loneliness (OR=1.26, 95% CI 1.11 to 1.44), depressive symptoms (OR=1.13, 95% CI 1.09 to 1.18), childhood trauma (OR=1.03, 95% CI 1.02 to 1.05) and life quality satisfaction (OR=0.63, 95% CI 0.49 to 0.80). Similarly, for NSSI among nursing staff, independent risk factors were identified, such as smoking frequency (OR=1.37, 95% CI 1.01 to 1.85), drinking frequency (OR=1.42, 95% CI 1.05 to 1.91), loneliness (OR=1.21, 95% CI 1.05 to 1.39), depressive symptoms (OR=1.13, 95% CI 1.09 to 1.18) and childhood trauma (OR=1.03, 95% CI 1.01 to 1.05). A nomogram for assessing SI/NSSI was established and demonstrated good calibration, with a Concordance Index of 0.82 (95% CI 0.79 to 0.86) for SI and 0.81 (95% CI 0.78 to 0.85) for NSSI.

The findings of this study can be used to identify nursing staff at risk of developing SI/NSSI. By using the developed nomograms for self-assessment, individuals might gain a better understanding of their occupational stress levels while performing routine work tasks. However, it should be noted that the study lacks external validation, which limits the generalisability of the findings at this stage.

To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.

Prospective cohort study.

Two comprehensive specialised hospitals in Ethiopia.

Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.

Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.

The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p

Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.

This study assessed the association between fine particulate matter (PM_2.5) exposure during pregnancy and stillbirth in Pakistan. We hypothesised that higher PM_2.5 exposure is linked to increased stillbirth risk.

A cross-sectional study using secondary data from the 2017 to 2018 Pakistan Demographic and Health Survey (PDHS), combined with satellite-derived PM_2.5 exposure data.

The study covered urban and rural areas across Pakistan, including all four provinces (Punjab, Sindh, Khyber Pakhtunkhwa and Baluchistan) and administrative regions (Gilgit-Baltistan (GB), Islamabad, Federally Administered Tribal Areas and Azad Jammu Kashmir).

The study included 9172 married women aged 15–49 with at least one birth in the past 5 years. Women with incomplete pregnancy outcome data were excluded.

PM_2.5 exposure was estimated using satellite data, matching PDHS clusters with the nearest air quality point via MATLAB. Monthly average exposure was categorised into quartiles.

Stillbirth, defined as pregnancy loss at ≥28 weeks gestation.

Multivariable logistic regression was used to assess the association between PM_2.5 and stillbirth, adjusting for maternal age, gravidity, wealth index, birth interval, previous adverse pregnancy outcome and region of residence. The stillbirth rate in Pakistan for the most recent pregnancy was 17.0 (14.5–19.9) per 1000 births, with highest rates (28.9) in Baluchistan province. The mean level of PM_2.5 exposure in Pakistan was 53.96 (SD 20.42; range 5.9–209.4) µg/m³. PM_2.5 exposure was higher for urban (56.43) than rural (51.87) pregnancies, highest in Sindh (78.06) and lowest in GB (13.41) provinces. For every 1 µg/m³ average increase in PM_2.5 during the pregnancy period, there was approximately 1% increase in stillbirth.

Increased PM_2.5 exposure was strongly associated with stillbirth risk. This underscores the need for targeted public health interventions, such as government regulations, emission controls and clean energy initiatives to protect pregnant women in high-risk areas.

Perioperative psychological symptoms are prevalent among patients undergoing lung surgery and can contribute to adverse clinical outcomes. Pharmacological interventions for these symptoms have inherent limitations. Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a promising non-invasive therapeutic approach. This study aims to evaluate the efficacy of taVNS in managing perioperative psychological symptoms in patients undergoing elective thoracoscopic pneumonectomy under general anaesthesia.

This single-centre, prospective, randomised, double-blind, controlled trial will enrol 176 patients scheduled for elective thoracoscopic lung resection. Participants will be randomly allocated to either the active taVNS or the sham taVNS groups in a 1:1 ratio. Both groups will receive 30 min active or sham stimulation sessions at four time points: (1) the afternoon prior to surgery, (2) the morning of the surgery, (3) following extubation and (4) the first afternoon postsurgery. The primary outcome is the incidence of perioperative anxiety, assessed using the Hospital Anxiety and Depression Scale-Anxiety subscale. Secondary outcomes include depression scores, stress index, sleep quality, pain scores, incidence of postoperative delirium, fatigue, cough symptoms and postoperative recovery quality, all evaluated through validated assessment tools. Analyses will be conducted using intention-to-treat and per-protocol populations.

The Ethics Committee of Affiliated Hospital of Xuzhou Medical University granted approval for the study with approval number: XYFY2024-KL444-01. Dissemination will be via national anaesthesia conferences and publication in the peer-reviewed literature.

Cognitive behavioural therapy (CBT) and interpersonal psychotherapy (IPT) are both efficacious treatments for depression, but it is less clear how both compare on outcome domains other than depression and in the longer term. Moreover, it is unclear which of these two psychotherapies works better for whom. This article describes the protocol for a systematic review and individual participant data (IPD) meta-analysis that aims to compare the efficacy of CBT and IPT for adults with depression on a range of outcomes in both the short and long term, and to explore moderators of the treatment effect. This study can enhance our understanding of treatments for depression and inform treatment personalisation.

Systematic literature searches will be conducted in PubMed, PsycINFO, EMBASE and the Cochrane Library from inception to 1 January 2026, to identify randomised clinical trials (RCTs) comparing CBT and IPT for adult depression. Researchers of eligible studies will be invited to contribute their participant-level data. One-stage IPD meta-analyses will be conducted with mixed-effects models to examine (a) treatment efficacy on all outcome measures that are assessed at post-treatment or follow-up in at least two studies, and (b) various baseline participant characteristics as potential moderators of depressive symptom level at treatment completion.

Ethical approval is not required for this study since it will be based on anonymised data from RCTs that have already been completed. The findings of the present study will be disseminated through a peer-reviewed journal or conference presentation.

To identify enablers and barriers for scaling up non-communicable disease (NCD) interventions across diverse global contexts and to map these factors to the WHO’s health system building blocks.

A multi-method qualitative study applying the Consolidated Framework for Implementation Research to analyse data from multiple projects nearing or completing scale-up.

Global Alliance for Chronic Diseases-funded implementation research projects conducted across 18 low- and middle-income countries and high-income settings.

Data was derived from documents (n=77) including peer-reviewed publications, policy briefs, and reports and interviews with stakeholders (n=18) (eg, principal investigators, medical professionals, public health workers).

Various context-specific interventions targeting sustainable scale-up of NCD (eg, diabetes, hypertension, cardiovascular disease) interventions at the community, primary care or policy levels.

The primary outcome was identifying contextual enablers and barriers to intervention scale-up. Secondary outcomes included exploring how these factors aligned with health system building blocks (eg, leadership/governance, healthcare workforce).

Twenty enablers (eg, intervention adaptability, strong stakeholder engagement, local empowerment) and 25 barriers (eg, resource limitations, intervention complexity, stakeholder burnout) were identified. Contextual alignment, supportive governance and capacity building were critical for sustainability, while cultural misalignment and socio-political instability frequently hampered scaling efforts.

Tailoring interventions to local health systems, ensuring stakeholder co-ownership and incorporating strategies to mitigate stakeholder burn-out are essential to achieving sustainable, scalable NCD solutions. Future research should focus on integrating systematic cultural adaptation, sustainable financing and workforce capacity building into scale-up planning.

First-degree relatives of colorectal cancer (CRC) patients have a twofold to fourfold increased risk of CRC. Tailored communication interventions have shown efficacy in improving their risk awareness and screening participation. While computer-based tailoring systems offer convenience, they often overlook the integration of healthcare professionals’ verbal input, potentially limiting effectiveness and long-term impact. To address this gap, we developed ScreenTalk, an intelligent voice-interactive tailored communication system that employs intelligent speech interaction to automate the tailoring process, enhance message credibility and improve scalability within CRC screening workflows.

This study is a two-arm, cluster-randomised controlled trial with a hybrid type I design involving 314 participants across three tertiary general hospitals in Guangzhou, China. Participants in both groups will receive usual care. Additionally, the intervention group will receive a 1-month tailored intelligent voice-interactive intervention, whereas the control group will receive unrelated health education to control for attention. Screening uptake (primary outcomes) and health beliefs (secondary outcomes) are measured at baseline and at 3 months, 6 months, 9 months and 12 month post the intervention. Implementation outcomes including reach, implementation, adoption and maintenance will be assessed through questionnaire, qualitative interviews and tailored system record.

The trial has been approved by the Ethics Committee of the Sun Yat-sen University (IRB No. L2024SYSU-HL-054). Information on the purpose and process of this study will be provided to the participants before recruitment, and written signatures will be collected from all participants to ensure their voluntary participation and protection of their rights and privacy.

International migrants comprise 3.6% of the global population and face systemic barriers to accessing sexual and reproductive health (SRH) services, such as contraception, safe abortion care and sexual function support. In high-income countries, policy frameworks vary widely, with migration status significantly influencing entitlement and access to host countries. This protocol outlines a planned study to systematically analyse SRH policies in high-income countries with strong migrant integration frameworks, aiming to identify policy gaps, assess inclusivity and inform recommendations to strengthen Australia’s SRH policy landscape.

This study employs a systematic policy analysis using the Joanna Briggs Institute scoping review methodology. Countries with ≥10% migrant populations and a Migrant Integration Policy Index health score ≥70 will be included. 13 countries meet these criteria, including Australia, Canada and Sweden. A comprehensive search of academic databases (PubMed, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature and ProQuest Public Health) and grey literature from governmental and non-governmental sources will be conducted. Data extraction will follow Bacchi’s ‘What’s the Problem Represented to Be?’ approach. Thematic analysis will combine deductive and inductive methods to examine the extent to which SRH policies address migrant and refugee needs, including sexual function, safe abortion care and fertility care. A comparative policy matrix will identify strengths, limitations and best practices.

As this study analyses publicly available policy documents, ethics approval is not required. Findings will be disseminated through peer-reviewed publications and policy briefs targeting stakeholders involved in SRH policy and migrant health.

About 30% of depressed patients suffer from a protracted course in which the disorder continues to cause significant burden despite treatment efforts. While originally developed for relapse prevention, mindfulness-based cognitive therapy (MBCT) has increasingly been investigated in depressed patients with such ‘difficult-to-treat’ courses. This is a protocol for an individual participant data (IPD) meta-analysis aiming to determine efficacy and potential moderators of MBCT treatment effects in this group based on evidence from randomised controlled trials.

Systematic searches in PubMed, Web of Science, Scopus, PsycINFO, EMBASE and the Cochrane Controlled Trials Register for randomised controlled trials were completed on 17 June 2024. Authors of identified studies have contributed IPD, and data extractions have been completed. An update search will be conducted immediately before the start of data analyses. We will investigate the following outcomes: (a) self-reported and observer-reported severity of depression symptomatology, (b) remission and (c) clinically meaningful improvement and deterioration. One-stage and two-stage IPD-MA will be conducted with one-stage models using the observed IPD from all studies simultaneously as the primary approach. One-stage IPD models will include stratified study intercepts and error terms as well as random effects to capture between-study heterogeneity. Moderator analyses will test treatment-covariate interactions for both individual patient-level and study-level characteristics.

The results will inform understanding of the use of MBCT in patients with current ‘difficult-to-treat’ depression and will contribute to arguments in favour of or against implementing MBCT as a treatment for this group. They will be published in a peer-reviewed journal and made available to stakeholders in accessible formats. No local ethical review was necessary following consultation with the Ethics and Governance Board of the University of Surrey. Guidance on patient data storage and management will be adhered to throughout.

Hypertension and depression frequently co-occur, complicating patient management and worsening outcomes. This scoping review aims to systematically map non-pharmacological interventions for managing comorbid hypertension and depression, providing insights into current practices and guiding future research.

Following the Joanna Briggs Institute guidelines and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews standards, a comprehensive search was conducted across multiple databases, including PUBMED, Embase, PsycINFO, CINAHL, Cochrane Library, Chinese Biomedical Literature Database and Chinese National Knowledge Infrastructure, covering the literature from January 2004 to December 2023. Studies were selected based on predefined inclusion criteria focusing on non-pharmacological or complex interventions. Data extraction was performed using the Template for Intervention Description and Replication checklist to ensure detailed and structured summaries of each intervention.

Fifteen quantitative studies were included, most of which were pilot randomised control trials, pre-post studies and with generally small sample sizes (20 to 2365). Interventions were categorised into integrated and coordinated care, behavioural and psychological interventions and physical and lifestyle interventions. Delivery methods varied, with most interventions being face-to-face, while a few used digital platforms such as mobile apps and telephone support. Disease-level and patient-level outcomes were mainly reported, while only three examined system-level outcomes. 13 of 15 included studies showed positive results in managing comorbidity. The variability in follow-up periods (ranging from 1 week to 12 months) and measurement instruments across studies limited the ability to draw consistent long-term conclusions.

This scoping review highlights the role of psychosocial and non-pharmacological interventions, particularly collaborative/integrated care and behavioural therapies, in managing comorbid hypertension and depression. These interventions consistently improve depressive symptoms, with mixed effects on blood pressure control. Further research is needed to standardise core outcomes and evaluate the long-term effectiveness and scalability of these interventions.

This study aimed to compare the predictive performance of novel adiposity indices (a body shape index (ABSI) and visceral adiposity index (VAI)) with traditional anthropometrics (body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR)) for cardiovascular disease (CVD) risk in urban China. Secondary objectives included evaluating composite indices derived from principal component analysis (PCA) and evaluating optimised risk stratification strategies.

A community-based cross-sectional study.

Urban and rural communities in Nanjing, China, from 2020 to 2023.

38 427 adults aged 35–79 years, recruited via stratified sampling. Individuals aged 79 years, who were pregnant or had severe illness or cognitive impairment were excluded.

The primary outcome was a CVD high-risk status (defined by Chinese guidelines). Secondary outcomes included detection rates, area under the curve (AUC), ORs and multicollinearity diagnostics.

Among participants, 23.3% (n=8905) were classified as high risk for CVD. In this study, WHtR demonstrated the greatest discriminative power (AUC=0.826, 95% CI 0.819 to 0.832), followed by a PCA-derived composite obesity index (COI; AUC=0.822). ABSI showed a clear risk gradient, with a 38.5% detection rate in the high-risk group (ABSI≥0.085), and VAI exhibited a modest but statistically significant effect (OR=1.026, p=0.001). Severe multicollinearity among traditional indices (variance inflation factor >40) was mitigated by COI. Combined models (eg, COI+ABSI+ VAI) achieved comparable AUC (0.825) with improved parsimony (AIC=17 4010.34). Age, hypertension and dyslipidaemia were key covariates (ORs=1.15–3.88, p

WHtR and composite indices (eg, COI) appeared to perform better than other indicators in predicting CVD risk, whereas ABSI and VAI enhance stratification in specific subgroups. Implementing WHtR-based screening in primary care, supplemented by composite indices and novel markers for high-risk individuals, may help optimise prevention strategies in urbanising Chinese populations.

To conduct a systematic review and narrative synthesis to identify barriers, facilitators and pre-existing interventions and describe the current status of initiatives/interventions aimed at improving access to quality trauma healthcare after injury in Pakistan.

Systematic review and narrative synthesis

MEDLINE (Ovid), Embase (Ovid), Web of Science (Clarivate Analytics), Cochrane (Wiley), Scopus and ProQuest, as well as grey literature.

Full-text peer-reviewed publications, including cross-sectional studies, cohort studies, case-control studies, randomised controlled trials and qualitative studies published in English from January 2013 to December 2023.

Two independent reviewers used a standardised tool to extract data variables to Excel. The quality of the included studies was evaluated using the CASP checklist. The barriers, facilitators and pre-existing interventions were mapped using the four delays framework, the Institute of Medicine (IOM) quality domains and the WHO health systems building blocks. The data were synthesised narratively to improve access to quality trauma care in Pakistan. This review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines.

The review included 20 studies. 19 studies reported 58 barriers to access to quality care. Six studies reported 20 facilitators, and eight studies described initiatives or interventions aimed at improving access to quality trauma healthcare after injury. According to the four delays framework, the receiving care stage of access to care was primarily studied in 16 studies, which identified 37 barriers and 13 facilitators across 5 studies. Regarding the quality of care according to IOM domains, the effectiveness of quality trauma care after an injury was studied in 15 studies, which identified 19 barriers and 10 facilitators across four studies. According to the WHO health system building blocks, most studies (n=15) described challenges in healthcare service delivery, with these 15 studies identifying 23 barriers and 3 studies identifying 4 facilitators.

Our findings highlighted the scarcity of available literature, identified barriers and facilitators and pre-existing interventions, which informed the need to develop feasible, sustainable and contextually relevant interventions to improve access to quality trauma care after injury in Pakistan.

Music-based training programmes, such as learning how to play an instrument or sing in a choir, have been suggested as potential interventions for promoting healthy brain ageing in older adults at risk of cognitive decline because of their ability to enhance cognitive functions and potentially promote neuroplasticity. However, there is limited empirical evidence in older adults at risk of dementia, especially that evaluates both piano and singing interventions and their effects on cognition and neuroplasticity. In this protocol, we outline a study to assess the efficacy of keyboard and singing music training programmes on reducing cognitive decline and other outcomes in older adults with Mild Cognitive Impairment (MCI).

This randomised, single-blind, controlled, parallel-group trial aims to enrol 432 individuals with MCI from the community in Sydney, Australia. Participants are randomly allocated to participate in either keyboard lessons, singing lessons or a film discussion control group once a week for 3 months. The primary objective is to assess the effectiveness of two music training programmes (keyboard and choral singing) for enhancing verbal memory after 3 months compared with control. Additionally, we will examine how these music-based interventions affect other aspects of cognition, mood, sleep, overall well-being, markers of brain plasticity and blood biomarkers of Alzheimer’s disease and neurodegeneration. Tertiary objectives are to identify factors that impact the success of the interventions, such as participation rates, engagement levels and key demographic and clinical features. Outcomes are collected at baseline and at 3 and 9 months. The primary endpoint analysis will include all randomised participants to estimate the treatment effect using intention-to-treat principles. Primary and secondary outcomes will be analysed using linear mixed models and effect size measures will be calculated.

This study will be the first robust, randomised controlled trial to assess the potential and relative value of music engagement for cognitive decline in high-risk MCI individuals, as well as broader effects on other markers of mental health, well-being and neurodegeneration. Co-designed with implementation in mind, the music interventions can potentially be delivered within memory clinic or community settings.

The Sydney University Human Research Ethics Committee (2023-026) has approved this protocol. The trial findings will be shared through conferences, publications and media.

Although the WHO and the Centers for Disease Control and Prevention (CDC) classify preconception health risks (PCHRs) into biomedical, behavioural and social categories, this classification remains theoretical, mainly inconsistent and lacks a scientifically robust framework. Data-driven clustering techniques may help clarify this complexity for policymakers and healthcare providers. This study aimed to assess the status of PCHRs and identify latent classes of these risks among women preparing for pregnancy.

This community-based cross-sectional study was conducted from 31 July to 16 August 2024 in Tigray, Ethiopia, among 865 married women planning to conceive within the next 6 months. Data were gathered through face-to-face interviews using a structured questionnaire. Risk factor indicators covering lifestyle behaviours, substance use, nutritional risks and related factors were developed based on guidelines from the WHO, the CDC and national recommendations. Latent class analysis (LCA) was employed to identify distinct classes of PCHRs, with the optimal number of classes determined using statistical fit indices, adequacy criteria and interpretability. The study also evaluated the overall distribution of PCHRs among participants.

The study took place in Tigray, Ethiopia, among married women intending to become pregnant within 6 months.

Burden of PCHRs and identified distinct latent classes of these risks within the participants.

All participants were exposed to at least four PCHRs, with 84.2% experiencing between 6 and 12 risk factors. The optimal LCA model identified four distinct classes of PCHRs: lifestyle behavioural risks (n=458, 52.9%), reproductive health risks and chronic medical conditions (n=106, 12.25%), nutritional risks and environmental exposure (n=149, 17.23%) and social determinants of health (n=152, 17.57%).

Our study reveals a high baseline level of PCHRs, with all participants exhibiting multiple risk factors for adverse pregnancy outcomes. The identification of four distinct risk profiles underscores the need for tailored risk-specific interventions, particularly in conflict-affected settings. Our findings point out the need for targeted preconception care and risk stratification in national health strategies to improve maternal and child health outcomes.

Proximal humeral fractures are increasingly common, particularly among older people, whereas the prognosis of surgical treatments for these fractures remains substantially uncertain. In China, where the ageing population is rapidly growing, high-quality prospective data on surgical outcomes, complications and cost-effectiveness are lacking. To address this gap, we propose to initiate a prospective, multicentre cohort study on surgical treatment for proximal humeral fractures in China—Cohort of Acute Shoulder Trauma (CAST) study.

The CAST is a multicentre, prospective cohort study enrolling patients with acute proximal humeral fractures undergoing surgical treatments at eight hospitals in China between May 2024 and December 2029. Patients can receive any of the surgical treatment methods which include percutaneous Kirschner wire fixation, external fixation, open reduction and internal fixation using locking plates or intramedullary nails, suture anchors and shoulder arthroplasty. We will collect patient-reported outcome measures (Quick Disabilities of the Arm, Shoulder and Hand), Constant-Murley, American Shoulder and Elbow Surgeons, EuroQol 5-Dimension and Visual Analogue Scale), physical examination results, imaging assessments (based on X-rays, ultrasound, CT and MRI scans), laboratory tests (including inflammatory cytokines) and data on medical costs. We will follow patients at 1 day, and at 1 month, 3 months, 6 months, 12 months and 24 months postoperatively. The planned sample size is 1500 patients.

The study protocol has been approved by the Ethics Committee of Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University (Approval No. 2024-ky-104(K)). Written informed consent will be obtained from all participants. Findings from the CAST study will be disseminated through peer-reviewed journals and academic conferences.

Atrial fibrillation (AF) constitutes a growing public health challenge. Consequently, the exploration of modifiable risk factors is essential for advancing AF prevention and management. While obstructive sleep apnoea is established as a risk factor for AF recurrence following catheter ablation, and its treatment with continuous positive airway pressure therapy reduces recurrence rates, the influence of non-sleep apnoea-related sleep indicators remains unclear. This systematic review aims to elucidate the association between these non-sleep apnoea-related sleep indicators and AF recurrence to inform optimised management strategies.

A comprehensive search will be performed in databases, including PubMed, Embase, the Cochrane Library, Chinese National Knowledge Infrastructure, VIP Database and Wanfang Data, covering publications from database inception to 27 August 2024. Study selection will be performed independently by two reviewers using predefined eligibility criteria, with the screening process documented in a referred Reporting Items for Systematic Review and Meta-Analysis-compliant flow diagram. Data will be extracted using standardised forms and risk of bias of included studies will be assessed with the Risk Of Bias In Non-randomised Studies-of Interventions tool. Non-sleep apnoea-related sleep indicators, including sleep duration, sleep quality, sleep latency, sleep efficiency, REM (Rapid Eye Movement)/NREM (Non-Rapid Eye Movement), etc, serve as exposure factors. The primary outcome is defined as AF recurrence, whereas the secondary outcome comprises quality of life measures among AF patients. Should sufficient data be available, a meta-analysis will be performed using appropriate statistical methods; otherwise, a narrative synthesis will be conducted.

This study uses publicly available data, so ethical approval is not required. The findings will be disseminated through peer-reviewed journals and scholarly platforms to inform clinical practice and future research.
