Video-assisted thoracoscopic surgery (VATS) lobectomy is a commonly employed surgical technique for the management of operable early stage non-small cell lung cancer (NSCLC). This procedure, however, is dependent on the patient’s ability to tolerate surgery. In light of this, stereotactic ablative radiotherapy (SABR) has emerged as a viable alternative treatment strategy for patients who are inoperable or who refuse surgery. Considering the lack of randomised controlled trials and the increased risk of bias in observational cohort studies, this study protocol proposes an emulated target trial design to investigate the causal effect of SABR, in comparison to VATS, on overall survival in operable early stage NSCLC patients.

Data on NSCLC patients will be collected from routinely collected university hospital records linked with German cancer registry data. This study protocol was developed using the target trial methodology outlined by Hernan et al. The protocol establishes specific parameters for key trial components in order to mitigate bias in the analysis of observational data and to facilitate the calculation of causal estimands. The target trial design that would be emulated is a multicentre open-label two-parallel arm superiority randomised trial. Mediators and confounding variables were determined through the use of a directed acyclic graph. The statistical analysis aims to measure the per-protocol and intention to treat effect of SABR versus VATS within 3 months of diagnosis, on survival, through the difference in restricted mean survival times, using weighted non-parametric Kaplan-Meier curves.

The Ethics Committee of the Medical Faculty of Martin Luther University Halle-Wittenberg with an approved addendum with Dnr 2023–112 has approved this study. The study uses anonymised routinely collected hospital and cancer registry data in accordance with applicable data protection regulations. Results will be disseminated through peer-reviewed publications and presentations at scientific conferences.

Non-communicable diseases (NCDs) have become the leading cause of mortality globally, with a sharp rise in Iran due to lifestyle changes and urbanisation. Although many NCD risk factors are modifiable, limited understanding of their determinants hinders effective prevention. To address this, the Prospective Epidemiological Research Studies in Iran (PERSIAN) Cohort was established in 2014 to study NCDs nationwide. The Sabzevar PERSIAN Cohort Study (SPECS) is the first in northeastern Iran, aiming to investigate environmental and social factors influencing NCDs in a unique regional context.

SPECS enrolled 5174 adults (aged 35–70 years) in northeastern Iran between January 2018 and January 2019 through a census and an online registration process. The baseline data collection included demographic verification, informed consent, health questionnaires, anthropometric measurements and biological samples (blood, urine, hair, nails). The annual follow-up began in April 2019, with full reassessments every 5 years over a 15-year period. The data is gathered via an active and passive follow-up, supported by trained staff and registry linkages.

Of the 5174 participants, 4241 (81%) remained in the study. Among the cohort, 54.5% were female, with a mean age of 50.5 years. The majority were married (93.5%), and nearly half had at least high-school education (46.5%) and moderate socioeconomic status (49.4%). Drug abuse history (smoking/drugs) was reported by about 15% of the sample. The mean body mass index was 26.9 kg/m², and the average blood pressure was higher in males (118.1/74.0 mm Hg) than in females (111.5/70.2 mm Hg). The common conditions included hypertension (22.8%), kidney stones (22.4%), fatty liver (15.4%) and diabetes (13.8%). Cancer had the highest treatment rate (100%), while fatty liver had the lowest (70.1%). Stroke had the highest mean age of onset (51.2 years), and epilepsy the lowest (23.7 years). All health data were self-reported.

SPECS, part of the national PERSIAN cohort initiative, is the only adult NCD-focused study in Khorasan Razavi. Its 15-year follow-up aims to generate region-specific insights into the incidence of NCDs and their risk factors. The ethnically homogeneous sample enhances statistical power, and the findings may inform culturally tailored health policies. While self-reported data have limitations due to bias, high initial participation and access to free healthcare support long-term engagement, especially among lower-income groups.

Enhancing maternal and infant health is a cornerstone of global health advancement. This can be achieved by building sustainable health monitoring systems that can accurately and reliably generate high-quality data and produce evidence-based recommendations for policymakers. By identifying gaps and strengths in current systems, this review aims to highlight current practices in monitoring maternal and infant health outcomes, including low birth weight.

The review will adopt the Arksey and O’Malley framework and the Joanna Briggs Institute’s Scoping Review Methods Manual. Three databases, including PubMed, Embase and CINAHL (Cumulative Index to Nursing and Allied Health Literature), as well as relevant grey literature sources, will be searched for articles describing active global population-based maternal and infant health monitoring systems published in English from the year of database inception till 30 September 2025. Two reviewers will independently screen titles and abstracts, followed by independent full-text screenings against predefined eligibility criteria, with data extracted using a data extraction form. After data extraction, a narrative synthesis will be performed. The findings will adhere to Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines.

This review is based on publicly available data; no ethical approval is required. The findings of this scoping review will be published in journals and presented at relevant conferences.

This study aimed to quantify how patient risk factors relate to COVID-19 severity across categories 1–5 in a prospective, hospital-based cohort. We hypothesised that greater severity would be associated with higher odds of intensive care unit (ICU) admission and in-hospital mortality. Secondary aims were to assess associations with age, viral variants, symptom clusters, lymphocyte count, fasting blood glucose and cytokine profiles.

Prospective cohort study.

A secondary-care/tertiary-care hospital and linked community settings in Cheras, Kuala Lumpur, Malaysia.

This study was nested within the COVGEN project, a prospective COVID-19 cohort conducted at Hospital Canselor Tuanku Muhriz UKM (HCTM), Cheras Health Clinic and the Bandar Tun Razak COVID-19 Assessment Centre in Cheras, Kuala Lumpur, Malaysia, from 1 August 2021 to 31 October 2022. 2532 participants were enrolled at baseline. Eligible participants were Malaysian citizens aged 12–18 years (paediatric/adolescent) or ≥18 years who had reverse transcription-polymerase chain reaction–confirmed COVID-19 at recruitment and resided in Kuala Lumpur or Selangor. Patients who had a clinically unstable condition and those who declined participation (personally or via a next-of-kin or legal representative) were excluded. This analysis included 559 patients hospitalised at HCTM; after excluding five with incomplete questionnaires, 554 remained for analysis (413 admitted to general wards and 141 to ICUs). Categories 3–5 comprised hospitalised patients, whereas categories 1–2 included hospitalised individuals and a subset recruited from community settings.

Primary outcomes included disease severity (categories 4–5 vs 1–3), ICU admission and in-hospital mortality. Secondary outcomes included associations with age strata, viral variant (delta vs omicron), symptom clusters, lymphocyte count, fasting blood glucose and cytokines: interferon gamma-inducible protein 10, interferon gamma, interleukins 8, 10, 2, 6 and 7 and tumour necrosis factor alpha.

141 of 554 (25.5%) patients required ICU care. Compared with milder categories, category 5 was associated with markedly higher odds of ICU admission (OR 204.50; 95% CI 37.54 to 1114.18; p55 versus

An increasing clinical severity category was strongly associated with ICU admission and mortality. Age, delta infection, specific symptom clusters, lymphopenia, hyperglycaemia and pro-inflammatory cytokines identified higher-risk patients, supporting risk-stratified management and prioritisation for enhanced monitoring.

To compare clinical radiography training experiences (structure, resources, participation, feedback) and self-perceived competence/practice readiness between public and private radiography centres in Lagos State, Nigeria.

Comparative cross-sectional survey design from August to October 2025 using a validated self-administered questionnaire distributed in person during departmental seminars and clinical debriefings at University of Lagos-affiliated centres.

Centre-based settings at public and private radiodiagnostic centres.

A total of 260 final-year students and recent graduates, 130 each from public and private radiodiagnostic centres. Inclusion criteria included: age ≥18 years, with ≥6 months clinical exposure, from centres affiliated to the University of Lagos. All participants completed the self-administered questionnaire. There were no interventions.

The primary outcome was the self-perceived competence/practice readiness, and the secondary was participation, extent and feedback mechanisms, measured as planned without protocol deviations. All variables were measured using validated items in the questionnaire.

Private centres significantly outperformed public centres in hands-on practice and feedback, with higher self-perceived competence (mean 35.6±5.7 vs 32.8±6.4; p=0.001). There were no significant differences in training structure (p=0.78). Public centres reported higher patient loads (86.2% vs 68.5%; p=0.001) but lower equipment availability (47.7% vs 72.3%; p

Private centres were associated with higher self-perceived competence and readiness, better resources and feedback, while public centres offered greater patient volumes. Hybrid placements and targeted infrastructure investment are recommended to help address disparities in perceived readiness.

This study aimed to address the spatial distribution and multilevel analysis of healthcare access barriers among women of reproductive age in Somalia.

The study was conducted across Somalia, an East African country facing significant spatial disparities in healthcare access. A cross-sectional study design was employed, using data from the 2020 Somali Demographic and Health Survey (SDHS). The data were analysed using both multilevel logistic regression and spatial analysis. To pinpoint barriers and identify statistically significant spatial clusters, the data were analysed using multilevel logistic regression in Stata V.17 and spatial analysis in R Studio (V.4.4.1), respectively.

The study population consisted of a weighted sample of 5118 women of reproductive age (15–49 years) from the SDHS.

Spatial analysis revealed significant regional heterogeneity, with high-prevalence areas concentrated in the northern region of Togdheer and a south-central cluster encompassing Galguduud, Hiiraan and Bakool. Multilevel analysis presented that women in the Bay region had nearly 10 times (AOR: 9.62) the risk of facing healthcare access barriers. While women in the highest quintile of wealth (AOR 0.21), those in higher education (AOR 0.30), those aged 45–49 (AOR 0.49) and not currently working (AOR 0.46) were significantly less likely to report access barriers.

Healthcare access barriers in Somalia are driven by a complex interplay of socioeconomic factors, specifically maternal age, education, employment and household wealth, and profound geographical disparities. Access barriers are not uniform but are geographically clustered in the south-central regions (Bay, Bakool, Hiiraan) and Togdheer in the northern region. Policy efforts must prioritise infrastructure investment in these identified high-burden hotspots while simultaneously dismantling systemic inequalities through the expansion of female education and financial protection schemes. This data-driven approach offers a definitive roadmap for decision-makers to equitably allocate resources and ensure that the most vulnerable populations are not left behind.

To identify the individual and community-level factors associated with barriers to accessing healthcare services among currently married women in Somalia.

A cross-sectional analysis using data from the 2020 Somalia Demographic and Health Survey.

Somalia.

A nationally representative sample of 30 311 currently married women aged 15–49 years with complete data on outcome and explanatory variables.

The primary outcome was ‘reporting at least one barrier to accessing healthcare’, a composite binary variable based on four specific problems: obtaining permission to go for treatment, getting money for treatment, distance to the health facility and not wanting to go alone.

A substantial majority (77.06%) of married women reported experiencing at least one barrier to accessing healthcare. Financial cost was the most common barrier (69.91%), followed by distance to health facilities (65.95%), reluctance to go alone (49.64%) and the requirement for permission (46.03%). Multilevel analysis confirmed that higher household wealth was strongly protective (richest vs poorest: adjusted OR (aOR)=0.27, 95% CI 0.24 to 0.32). Paradoxically, factors typically considered protective were associated with increased barriers: women with secondary education (aOR=1.19, 95% CI 1.00 to 1.41) and those with educated husbands (aOR=1.23, 95% CI 1.14 to 1.33) reported more obstacles. Similarly, urban residents faced higher odds of barriers than their nomadic counterparts (aOR=1.40, 95% CI 1.27 to 1.55). Significant regional disparities were evident, with community-level context explaining 26.30% of the total variance in reporting barriers.

Access to healthcare for married women in Somalia is predominantly hindered by economic, educational and community-level constraints. Targeted interventions addressing socioeconomic disparities, infrastructural deficits and specific community contexts are essential to alleviate these barriers.

To assess the levels of knowledge, attitudes and practices (KAP) toward skin cancer prevention among Malaysian adults and to examine differences in KAP across socio-demographic groups.

Cross-sectional online survey.

Community-based study conducted in Malaysia using social media recruitment.

A total of 386 adults aged ≥18 years residing in Malaysia. Most participants were young adults (86.3%), female (55.4%) and of Chinese ethnicity (65.5%). Healthcare professionals were excluded.

Primary outcomes were levels of knowledge, attitude and preventive practices toward skin cancer, measured using the validated KAP-SC-Q (Knowledge, Attitude and Practice of Skin Cancer Questionnaire) and categorised as poor, moderate or good. Secondary outcomes included differences in KAP across socio-demographic and clinical characteristics, analysed using independent t-tests and ² tests.

Over half of participants demonstrated poor knowledge of skin cancer (56.0%) and the vast majority showed inadequate preventive practices (84.2%), while attitudes toward skin cancer were predominantly positive (62.4%). Significant differences in mean KAP scores and categorical levels were observed across several socio-demographic variables. Participants with tertiary education had higher knowledge (14.32 vs 12.61) and attitude scores (20.01 vs 15.95; p

Malaysian adults exhibited limited knowledge and very poor preventive practices toward skin cancer despite generally positive attitudes. These findings highlight substantial gaps between awareness and behaviour and support the need for targeted public health interventions to correct misconceptions, improve risk perception especially in high-risk groups and promote effective ultraviolet protection behaviours.

The transition from clinical practice to an academic role presents a multifaceted challenge for anaesthesia master’s students in Iran, as it demands not only clinical expertise but also the development of educational competencies. This protocol outlines a sequential multimethod study designed to explore the dimensions of this role transition, identify the challenges and facilitators inherent in assuming a clinical educator role, and ultimately provide a foundation for evidence-based educational interventions.

This sequential multimethod protocol comprises three phases. Phase I involves qualitative thematic content analysis using semistructured focus groups and, where necessary, individual interviews with MSc anaesthesia students to explore experiences of role transition. Qualitative data will be analysed using Braun and Clarke’s six-phase approach. Phase II consists of an integrated review of the literature to synthesise existing evidence on transition to clinical educator roles in anaesthesia and related healthcare disciplines. Phase III integrates findings from both phases using the Pillar Integration Process to generate a comprehensive, evidence-informed framework of role transition.

Ethical approval for the study has been obtained from Tehran University of Medical Sciences (IR.TUMS.SPH.REC.1403.236), and written informed consent will be secured from all participants. Findings will be disseminated through publications in reputable peer-reviewed journals and presentations at national and international conferences, contributing to the refinement of training programmes for clinical educators within anaesthesia education.

Global discussions surrounding the medical use of marijuana have gained momentum; yet in Malaysia, cannabis remains strictly prohibited under the Dangerous Drugs Act 1952. Despite its legal status, there is growing public discourse on its potential therapeutic benefits. Understanding public acceptance is critical for informing future health policies and public education efforts.

This study used a cross-sectional design, web-based survey among Malaysians aged 18 years and above using convenience and snowball sampling methods. The survey collected data on sociodemographic characteristics, lifestyle factors (eg, smoking and drug use), awareness of medical marijuana and perceived risk. Multivariable logistic regression analysis was performed to identify factors associated with acceptance of medical marijuana decriminalisation.

Out of 2047 respondents, 88.4% supported medical marijuana decriminalisation based on clinical evidence. Key predictors of acceptance included male gender (adjusted OR (AOR) 1.71; 95% CI 1.29 to 2.26), higher education (Bachelor’s degree AOR 1.56; 95% CI 1.09 to 2.23 and Master’s/PhD AOR 2.04; 95% CI 1.34 to 3.10), self-employment (AOR 1.84; 95% CI 1.22 to 2.77) and private sector employment (AOR 1.40; 95% CI 1.03 to 1.89). Behavioural factors, such as smoking (AOR 1.58; 95% CI 1.10 to 2.27), prior drug use (AOR 1.86; 95% CI 1.30 to 2.67) and low perceived risk (AOR 5.82; 95% CI 3.48 to 9.73), were also significantly associated with acceptance.

A large proportion of Malaysian adults supported the clinical use of medical marijuana. Acceptance was strongly associated with demographic and behavioural factors, particularly gender, education and perceived risk. These findings may guide the development of targeted public health education and inform future discussions on regulatory approaches in Malaysia.

The work of receptionists in general practice is evolving rapidly and becoming more complex due to a number of changes within primary and community care services, such as increased digitalisation. In under-served areas, these changes have been further complicated by under-resourcing and workforce challenges around staff recruitment and retention. The National Health Service (NHS) 10-year health plan is set to accelerate further significant changes. There is limited understanding about how and why these changes and workforce challenges are impacting and will impact the future work of receptionists in general practice in under-served areas.

This realist review will build on an existing programme theory related to general practitioner workforce sustainability. The review will examine what works, for whom, how and under what circumstances for receptionist work in general practice, in under-served areas. For example, how influences such as the expectations of patients (in under-served communities), poor staffing or limited career progression. Key stakeholders, including public contributors and individuals from general practice settings, will inform the realist review.

The review will be conducted using existing secondary and grey literature sources. The search strategy comprises five electronic databases: Medline, Embase, PsycINFO, CINAHL and Web of Science Core Collection (SCIE, SSCI, AHCI) with a date limit of 2015 applied to the search. The review will follow Pawson’s five steps: (1) shaping the scope of the review; (2) searching for evidence; (3) document selection and appraisal; (4) data extraction and (5) data synthesis. The findings will be reported in accordance with the Realist and Meta-narrative Evidence Synthesis Evolving Standards.

Ethical approval is not needed for secondary analysis. The findings of this review will contribute to ongoing work as part of our ‘Workforce Voices’ programme of research. They will be disseminated to policymakers, commissioners, providers of health and social care and primary care and community healthcare teams through peer-reviewed publications, members of the public, conference presentations, social media and recommendations.

There is a global rise in the burden of childhood obesity, increasing the risk of early onset adult obesity. Most developing countries face the double burden of malnutrition; overnutrition as overweight/obesity and undernutrition.

To determine the current burden and determinants of childhood thinness, overweight and obesity using national survey data.

Data from a cross-sectional survey conducted in 2022 were used.

Data from the seventh Demographic Health Survey conducted in Ghana were used.

The participants included 4417 children ≤59 months.

The seventh Ghana Demographic Health Survey in 2022 employed a two-stage stratified cluster sampling design, selecting 618 clusters to create a nationally representative sample. Weight and height were measured using the SECA 874U scale and Shorrboard, respectively. Children’s heights were measured recumbent (24 months). Multivariate logistic regression was used to assess the relationship between thinness and obesity, as well as the independent factors.

The outcome variable was obesity, determined by a WHZ of >+2SD.

The weighted prevalence of overweight/obesity and thinness in children under 5 years is 9.9% and 5.2%, respectively. Children who were overweight or obese had a mean age of 23.11 months, those who were thin or severely thin had a lower mean age of 21.02 months, and those with normal nutritional status were relatively older, with a mean age of 28.41 months. The Upper West, Northeast and Northern regions had the lowest densities of obesity. In the multivariate logistic regression model, children residing in Ashanti, Oti, Northern, North East and Upper East regions had significantly reduced odds of being obese compared with those in the Ahafo region. The average haemoglobin for those overweight/obese was 10.8 g/dL, and 10.7 g/dL for those who were normal and marginally reduced, 10.5 g/dL for those who were thin.

Regional disparities, maternal nutritional status, socioeconomic conditions and unsafe water sources were significant determinants of child nutrition outcomes. These findings call for targeted, multipronged interventions that integrate maternal-child nutrition, safe water, sanitation and regional context.

Intermittent theta-burst stimulation (iTBS) is a non-invasive brain stimulation technique that has been shown to improve cognition and mood when applied to certain brain structures and regions. Despite research demonstrating that iTBS may have clinical utility in treating cognitive and mood changes, no study has yet been conducted to explore the potential to modulate the neurophysiological changes that can underpin cognitive and mood changes during the menopause transition. Cognitive and psychological symptoms are commonly reported by females experiencing the menopause transition, and it is thought that these symptoms arise due to various neurophysiological, metabolic and endocrinological changes. Despite being common, there is a lack of treatments available for managing these symptoms and a scarcity of data regarding the mechanisms by which they occur.

The aim of this 5-week randomised, sham-controlled, double-blinded pilot clinical trial (n=72) is to assess the underlying mechanisms of action of iTBS in females in the late menopause transition and the relationship with cognition and mood. Data will be analysed using Stata^TM. Normality checks will guide the choice between parametric and non-parametric tests. Generalised linear models will assess within-subject and between-subject effects across timepoints, with additional regression analyses exploring associations between biomarkers, cognition and mood. Effect sizes, CIs and relevant test statistics will be reported, with significance set at p

The study protocol has been reviewed and ethically approved by the Western Sydney University Human Research Ethics Committee (H16200; 8 November 2024). All participants will provide written informed consent prior to enrolment. Results from this trial will be disseminated via peer-reviewed publications and conference presentations, with findings shared in accordance with open science and data transparency principles.

Global migration has steadily risen, with 16% of the UK population born abroad. Migrants (defined here as foreign-born individuals) face unique health risks, including potential higher rates and delays in diagnosis of infectious and non-communicable diseases, compounded by significant barriers to healthcare. UK Public Health guidelines recommend screening at-risk migrants, but primary care often faces significant challenges in achieving this, exacerbating health disparities. The Health Catch-UP! tool was developed as a novel digital, multidisease screening and catch-up vaccination solution to support primary care to identify at-risk adult migrants and offer individualised care. The tool has been shown to be acceptable and feasible and to increase migrant health screening in previous studies, but to facilitate use in routine care requires the development of an implementation package. This protocol describes the development and optimisation of an implementation package for Health Catch-UP! following the person-based approach (PBA), a participatory intervention development methodology, and evaluates our use of this methodological approach for migrant participants.

Through engagement with both migrants and primary healthcare professionals (approximately 80–100 participants) via participatory workshops, focus groups and think-aloud interviews, the study aims to cocreate a comprehensive Health Catch-UP! implementation package. This package will encompass healthcare professional support materials, patient resources and potential Health Catch-UP! care pathways (delivery models), developed through iterative refinement based on user feedback and behavioural theory. The study will involve three linked phases (1) planning: formation of an academic–community coalition and cocreation of guiding principles, logic model and intervention planning table, (2) intervention development: focus groups and participatory workshops to coproduce prototype implementation materials and (3) intervention optimisation: think-aloud interviews to iteratively refine the final implementation package. An embedded mixed-methods evaluation of how we used the PBA will allow shared learning from the use of this methodology within the migrant health context.

Epilepsy prevalence varies widely across Nigeria, with rates ranging from 3.1 to 37.0/1000 population. There have been no studies on epilepsy prevalence and treatment gap in the Northeast Region of Nigeria. This study aimed to study epilepsy prevalence and the epilepsy treatment gap (ETG) in an urban and a rural community in Northeast Nigeria.

Cross-sectional, community-based survey.

Epilepsy screening of residents in two communities in Northeast Nigeria using a WHO screening tool and a validated study questionnaire from 1 March to 10 June 2022.

8599 community residents aged ≥2 years.

Prevalence of epilepsy, active epilepsy, ETG and associated factors.

We screened 8599 residents, of whom 88 had epilepsy. Crude epilepsy prevalence was 10.2 per 1000 and was three times higher in the rural than in the urban community (18.5 vs 6.4; ²=26.79, p2=0.087, p=0.768). Logistic regression analysis showed that the ETG was associated with a lack of counselling (OR 15.8, 95% CI 3.5 to 70.7, p

The prevalence of epilepsy in Bauchi State was within the range reported in Nigeria but three times higher in the rural than in the urban community. A high ETG was associated with poor counselling of people with epilepsy. Epilepsy counselling, health education and wider access to neurology services could reduce the burden of epilepsy in Northeast Nigeria.
