Implications for practice and research Low-paediatric-volume emergency departments (EDs) can increase paediatric readiness by improving diagnostic tools, expanding paediatric expertise (eg teleconsultation) and using electronic clinical decision support. Further research is needed to examine the costs and effectiveness of specific interventions to improve readiness in low-volume paediatric EDs.
Children sometimes have subtle illness presentations and symptom overlap with non-serious conditions.
Commentary on: Family caregivers’ burden, patients’ resourcefulness, and health-related quality of life in patients with colorectal cancer.
Practice: Treat the patient, and also treat the family and caregiver; help patients build or activate their resourcefulness, as resourcefulness can be a learnt skill. Research: Additional work should identify targets for improving patient resourcefulness.
Patients with colorectal cancer face treatments that can bring significant financial burden, physical strain and relationship changes which can affect quality of life. These stressors may be mitigated by coping ability, particularly resourcefulness, which reflects the ability of the patient to independently perform daily tasks and seek help when needed. The patient experience and need for care can affect caregivers as well, leading to caregiver burden: an accumulation of the negative responses to the caregiver that result from providing care, including disrupted schedules, financial and...

Macronutrients serve as principal sources of energy, structural components, and regulators of physiological processes. However, the optimal macronutrient combination for health remains unclear. While previous studies indicate that dietary macronutrient composition influences immune function, many have examined individual nutrients in isolation, failing to reflect the interactive effects of macronutrients. This study addresses this gap by examining how varying ratios of dietary carbohydrates, proteins, and lipids modulate serum cytokine responses to lipopolysaccharide challenge in Swiss albino mice. Male and female Swiss albino mice (n = 6 per group), aged 6–8 weeks, were randomly assigned to six purified isocaloric diets with differing macronutrient ratios for 15 weeks. Body weights were monitored to assess nutritional status. Serum levels of TNF-α, IL-6, IL-1β, and IL-10 were measured in unchallenged mice and after three hours of intraperitoneal LPS administration. Mice fed high-carbohydrate, low-protein diets had the highest weight (33.1 g ± 1.1), while those on high-lipid, low-protein diets had the lowest (28.3 g ± 0.6). Plasma levels of TNF-α and IL-10 varied significantly (pTobacco 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.
Cognitive impairment and upper limb impairment are common complications following stroke, but rehabilitation interventions targeting post-stroke cognitive and upper limb motor deficits remain understudied. Transcutaneous electrical nerve stimulation, including transcutaneous vagus nerve stimulation (tVNS) and transcutaneous spinal cord stimulation (tSCS), can potentially alleviate cognitive impairment and promote motor recovery. Although tVNS and tSCS may facilitate neuroplasticity following stroke, their effects on cognitive and upper limb motor outcomes have not been sufficiently studied. Therefore, the proposed clinical trial will investigate the effects of tVNS and tSCS on cognitive function and upper limb motor function in people with chronic stroke.
A three-arm sham-controlled single-blind parallel-group randomised controlled trial will be performed with people with chronic stroke. All participants (n=90) will be randomly allocated to receive 18 sessions of intervention with different stimulation protocols (tVNS, tSCS and sham stimulation) at a 1:1:1 ratio. All participants will receive upper limb exercises concurrent with the corresponding stimulation protocols for 45 min in each session, three sessions per week, for 6 weeks. The primary outcomes will be the Montreal Cognitive Assessment and Fugl-Meyer Assessment for Upper Extremity. The secondary outcomes will be the Rivermead Behavioural Memory Test, Digit Span Test, Trail Making Test, Wolf Motor Function Test, maximum isometric voluntary contraction of the elbow, muscle stiffness of the elbow extensor and flexor, Arm Activity Measure, Oxford Participation and Activity Questionnaire and 12-item Short-Form Survey. All outcomes will be assessed at baseline, after 9 and 18 sessions of the intervention, and 1 month after the cessation of the intervention.
Ethical approval has been obtained from the Human Subjects Ethics Committee of The Hong Kong Polytechnic University (HSEARS20221011002). The results yielded from this study will be submitted for publication in peer-reviewed journals and at international conferences.
The ‘time-limited trial’ for patients with critical illness is a collaborative plan made by clinicians, patients and families to use life-sustaining therapies for a defined duration. After this period, the patient’s response to therapy informs decisions about continuing recovery-focused care or transitioning to comfort-focused care. The promise of time-limited trials to help navigate the uncertain limits and benefits of life-sustaining therapies has been extensively discussed in the palliative and critical care literature, leading to their dissemination into clinical practice. However, we have little evidence to guide clinicians in how to conduct time-limited trials, leading to substantial variation in how and why they are currently used. The overall purpose of this study is to characterise the features of an optimal time-limited trial through a rich understanding of how they are currently shaping critical care delivery.
We are conducting an observational, multicentre, focused ethnography of time-limited trials in patients with acute respiratory failure receiving invasive mechanical ventilation in six intensive care units (ICUs) within five hospitals across the US. Study participants include patients, their surrogate decision makers and ICU clinicians. We are pursuing two complementary analyses of this rich data set using the open-ended, inductive approach of constructivist grounded theory and, in parallel, the structured, deductive methods of systems engineering. This cross-disciplinary, tailored approach intentionally preserves the tension between time-limited trials’ conceptual formulation and their heterogeneous, real-world use.
This study has been reviewed and approved by the University of Wisconsin Institutional Review Board (IRB) as the single IRB (ID: 2022-1681; initial approval date 23 January 2023). Our findings will be disseminated through peer-reviewed publication, conference presentations, and summaries for the public.
To explore why there is variation in implementation of multifactorial falls prevention practices that are recommended to reduce falls risks for older patients in hospital.
Mixed method, realist evaluation.
Three older persons and three orthopaedic wards in acute hospitals in England.
Healthcare professionals, including nurses, therapists and doctors (n=40), and patients aged 65 and over, and carers (n=31).
We examined mechanisms hypothesised to underpin the implementation of multifactorial falls risk assessment and multidomain, personalised prevention plans.
We developed an explanation detailing that how contextual factors supported or constrained implementation of recommended falls prevention practices.
Nurses led delivery of falls risk assessment and prevention planning using their organisation’s electronic health records (EHR) to guide and document these practices. Implementation of recommended practices was influenced by (1) organisational EHR systems that differed in falls risk assessment items they included, (2) competing priorities on nurse time that could reduce falls risk assessment to a tick box exercise, encourage ‘blanket’ rather than tailored interventions and that constrained nurse time with patients to personalise prevention plans and (3) established but not recommended falls prevention practices, such as risk screening, that focused multidisciplinary communication on patients screened as at high risk of falls and that emphasised nursing, rather than Multidisciplinary Team (MDT), responsibility for preventing falls through constant patient supervision.
To promote consistent delivery of multifactorial falls prevention practices, and to help ease the nursing burden, organisations should consider how electronic systems and established ward-based practices can be reconfigured to support greater multidisciplinary staff and patient and carer involvement in modification of individual falls risks.
To analyse trends and characteristics of multidrug-resistant (MDR) bacteria over the past 7 years, in relation to patterns of antimicrobial use, to inform rational antimicrobial use and strengthen hospital infection control measures.
Retrospective cohort study.
A large teaching hospital in Tianjin, a major metropolitan city in northern China.
A total of 190 352 inpatients aged >18 years, admitted between 1 January 2017 and 31 December 2023, were included. Patients were eligible if they had complete clinical data and met the five quality control indicators for multidrug-resistant bacteria (QC-MRB), defined in the ‘Hospital Infection Surveillance Specifications’ (WS/T 312–2023). Patients with MDR infections before admission or those with duplicate results from multiple specimens were excluded.
Statistical analysis revealed a detection rate of 12.11% for the five QC-MRB and an incidence rate of 0.20%. The findings also indicated an upward trend in the detection and incidence rates of carbapenem-resistant Enterobacteriaceae, despite a relatively stable rate of antimicrobial use over 7 years. A positive correlation was observed between the incidence of MDR bacteria and the intensity of antimicrobial use within the hospital setting.
The hospital’s bacterial data align with national trends. It established an interdisciplinary management framework for clinical data analysis and prediction of antimicrobial resistance. This approach enhances infection control measures and supports the rational use of antimicrobials.
Adenotonsillectomy is the primary treatment for type 1 obstructive sleep apnoea (OSA1). Although polysomnography (PSG) remains the gold standard for measuring Apnoea-Hypopnoea Index, it is a labour-intensive procedure and does not correlate with improvements in quality of life postadenotonsillectomy. Mouth breathing is associated with poorer quality of life in children. Mandibular movement (MM), which measures mouth opening, is a validated measure of respiratory effort that can be easily and safely assessed in children using the JAWAC technology. This study aims to evaluate the relationship between changes in quality of life and changes in mouth opening in children with OSA1 after undergoing adenotonsillectomy. Secondary objectives include evaluating changes in quality of life, clinical symptoms and other MM and PSG metrics in the same population.
This exploratory, non-randomised, monocentric, prospective cohort study with a non-blinded single arm will include 50 children aged 3–7 years, undergoing adenotonsillectomy at the Clinique Saint Jean, Montpellier, France. Quality of life will be measured using the parent version of the Paediatric Quality of Life Inventory and MM metrics will be measured during PSG using the JAWAC system during the inclusion visit and 3 months after adenotonsillectomy. The primary outcome will be the correlation between the changes in quality of life and mouth opening (1/10 mm) postadenotonsillectomy. Secondary analyses will evaluate changes in clinical symptoms, PSG measures and other MM metrics including respiratory effort, as well as the associations between these measures.
This study was approved by an independent ethics committee (Comité de Protection des Personnes Est) on 24 March 2025 (2024-A02761-46) and will be conducted in accordance with French law, good clinical practice and the guidelines of the Declaration of Helsinki. Study findings will be disseminated through international peer-reviewed journal articles as well as public, academic presentations at national and international conferences.
An abnormal composition of gut bacteria along with alterations in microbial metabolites and reduced gut barrier integrity has been associated with the pathogenesis of chronic autoimmune and inflammatory rheumatic diseases (AIRDs). The aim of the systematic review, for which this protocol is presented, is to evaluate the clinical benefits and potential harms of therapies targeting the intestinal microbiota and/or gut barrier function in AIRDs to inform clinical practice and future research.
This protocol used the reporting guidelines from the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol. We will search Embase (Ovid), Medline (Ovid) and the Cochrane Library (Central) for reports of randomised controlled trials of patients diagnosed with an AIRD. Eligible interventions are therapies targeting the intestinal microbiota and/or gut barrier function including probiotics, synbiotics, faecal microbiota transplantation, live biotherapeutic products and antibiotics with the intent to modify disease activity in AIRDs. The primary outcome of the evidence synthesis will be based on the primary endpoint of each trial. Secondary efficacy outcomes will be evaluated and selected from the existing core domain sets of the individual diseases and include the following domains: disease control, patient global assessment, physician global assessment, health-related quality of life, fatigue, pain and inflammation. Harms will include the total number of withdrawals, withdrawals due to adverse events, number of patients with serious adverse events, disease flares and deaths. A meta-analysis will be performed for each outcome domain separately. Depending on the type of outcome, the quantitative synthesis will encompass both ORs and standardised mean differences with corresponding 95% CIs.
No ethics approval will be needed for this systematic review. We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to disseminate the study results through a peer-reviewed publication.

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.
Sleep problems are an escalating global health concern, with prevalence estimates ranging from 8.3% to 45%. Physicians are disproportionately affected, with rates around 44% compared with 36% in the general population. In Bangladesh, reported rates range from 32% to 58%, with physicians being particularly vulnerable. Poor sleep among physicians is strongly linked to burnout, medical errors and increased mental health risks. Despite these serious implications, existing evidence from Bangladesh remains fragmented and inconsistent, limiting its utility for health policy and workforce interventions. This review therefore seeks to generate reliable pooled prevalence estimates and identify key determinants of sleep problems among Bangladeshi physicians.
The research team will search the PubMed, Scopus, Web of Science, EMBASE, PsycInfo, ProQuest Medical, CINAHL, Google Scholar and BanglaJOL electronic and regional databases following Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines for published studies from inception until 1 August 2025, using truncated and phrase-searched keywords, relevant medical subject headings and citation chaining from grey literature. Observational cross-sectional studies published within the predefined timeframe, using validated assessment tools, and published in English or other major international languages will be prioritised for inclusion. Review papers, case reports, case series, intervention studies, commentaries, preprints, meeting abstracts, protocols, unpublished articles and letters will be excluded. Two independent reviewers will screen the retrieved papers using the Rayyan web-based application, with any disagreements resolved by a third reviewer. Quantitative estimates of sleep problems, including prevalence, duration, quality and associated risk factors among Bangladeshi physicians will be extracted. A narrative synthesis and meta-analysis will be performed to assess the pooled prevalence using a random effects meta-analysis model. Forest and funnel plots will be generated for visualisation. Heterogeneity will be assessed using the I2 statistic, with sensitivity or subgroup analysis conducted as required. The quality of included studies will be evaluated using Joanna Briggs Institute critical appraisal tools for observational study designs. All statistical analysis will be conducted using Jamovi V2.7.6, R V4.3.2 ‘meta’ packages and GraphPad Prism V9.0.2.
This review will synthesise evidence from existing published literature. While completing the findings, the findings will be submitted to an international peer-reviewed journal and disseminated through conferences, policy forums and stakeholders’ networks to inform future research and interventions.

Chronic subdural haematoma (CSDH) is a common neurosurgical condition in older adults, with a recurrence rate of approximately 7.1–13% after burr-hole drainage. Although surgical adjuncts such as subdural drains and middle meningeal artery embolisation may reduce recurrence, these are not suitable for all patients. Pharmacological strategies, including tranexamic acid, Goreisan and carbazochrome sodium sulfonate hydrate, have shown potential, but high-level evidence remains lacking. A prior retrospective study suggested that a triple oral regimen combining these agents may reduce recurrence. This randomised controlled trial aims to evaluate its efficacy and safety.
This is a prospective, multicentre, open-label, randomised controlled trial conducted across six hospitals in Ibaraki, Japan. A total of 180 patients undergoing first-time burr-hole surgery for CSDH will be randomised 1:1 to receive either triple therapy (Goreisan 7.5 g/day, carbazochrome sodium sulfonate hydrate 90 mg/day and tranexamic acid 750 mg/day for up to 90 days) or standard postoperative care. The primary outcome is recurrence requiring reoperation within 90 days. Secondary outcomes include time to recurrence and haematoma volume reduction on serial CT imaging. All analyses will follow the intention-to-treat principle, using logistic regression, Cox proportional hazards models and mixed-effects models.
Written, informed consent will be obtained from all participants at each participating hospital by trained staff from that hospital. The trial protocol has been approved by the ethics committee of the University of Tsukuba Hospital (approval no. TCRB23-025) and the Institutional Review Boards of all participating centres. Study findings will be disseminated through presentations at scientific conferences and publications in peer-reviewed journals. A summary of the results will also be provided to participating institutions and made publicly available in accordance with the BMJ Open data sharing policy.

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.
Women who develop gestational diabetes mellitus (GDM) have a 60% lifetime risk of developing type 2 diabetes mellitus (T2D), which is already elevated within the first decade following childbirth. Despite the impact of lifestyle interventions to reduce long-term T2D risk in women with previous GDM, successful implementation of lifestyle interventions remains a barrier. Metformin is recommended for adults at increased risk of developing T2D; however, there is limited evidence of tolerability in the early postpartum period. Glucagon-like peptide 1 receptor agonists (GLP-1 RA) are effective at improving glycaemic status and body weight. However, GLP-1 RA have not been evaluated in the postpartum population. Finally, physical activity monitors may support behaviour changes related to physical activity to reduce long-term risk of T2D but are yet to be studied following GDM.
This will be a multicentre, randomised, open-label interventional pilot study. Using a 2x2 factorial design, we will examine the feasibility and acceptability of a pharmacotherapy intervention and a physical activity intervention in women with previous GDM at increased risk of developing T2D. Participants will be recruited from tertiary referral hospitals in Australia and will be randomised to receive either metformin alone or in combination with a GLP-1 RA and subsequently randomised to either a physical activity intervention involving activity monitor use, or usual care for 6 months, followed by a 6-month follow-up period. Primary feasibility outcomes include the acceptability and safety of the metformin and GLP-1 RA as measured through pill and injection counts, acceptability questionnaire and adverse events.

Persistent somatic symptoms and functional disorders are conditions requiring a biopsychosocial approach to care, often from multiple professionals. The fragmentation of care common in most health systems results in unsatisfactory and challenging care experiences. Collaborative care networks form an important route towards improving outcomes and the overall experience of care for patients and professionals. While we have a good idea of what such collaborative care networks can look like, we lack knowledge on the practicalities of implementing change in such networks.
The core objective of this study is to implement change in a collaborative care network for persistent somatic symptoms and functional disorders care. Our questions were twofold: first, what are examples of realistic action processes to improve such collaborative care networks? Second, what are, in our experience, conditions for an effective change process in such a collaborative care network?
Participatory action research approach embedded within an active regional network between May 2023 and May 2024. The process was led by an action group who selected objectives and related actions with the aim of improving the network, leading to better care for people with persistent somatic symptoms and functional disorders as well as improving satisfaction among professionals.
ALK Netwerk Salland, a regional network of professionals and experts-by-experience, focused on care of persistent somatic symptoms. This network is based in the Salland region in the east of the Netherlands, centred around the city of Deventer.
The action group was made up of local stakeholders including experts-by-experience and health and social care professionals, facilitated by a researcher-in-residence. Other participants included members of the regional network who provided input towards the different objectives.
Over the course of a year, three objectives were selected and enacted, including assessing the resources of the network, improving knowledge of treatment options and improving the shared vision of care. The process faced some challenges, such as changes in action group members and a lack of resources and time to enact changes. However, by having a trusted and engaged team, working with an active network, we were able to enact significant changes to the network, which may be sustained and built on through the ongoing action group.
Future participatory action research studies would benefit from a trusted and embedded researcher-in-residence, meaningful involvement early in the process of experts-by-experience, and serious consideration of realistic outcome measures to monitor for evaluation of changes made.
Shoulder osteoarthritis most commonly affects older adults, causing pain, reduced function and quality of life. Total shoulder replacements (TSRs) are indicated once other non-surgical options no longer provide adequate pain relief. Two main types of TSRs are widely used: anatomic TSR (aTSR) and reverse TSR (rTSR). It is not clear whether one TSR type provides better short- or long-term outcomes for patients, and which, if either, is more cost-effective for the National Health Service (NHS).
RAPSODI-UK is a multi-centre, pragmatic, two-parallel arm, superiority randomised controlled trial comparing the clinical- and cost-effectiveness of aTSR versus rTSR for adults aged 60+ with a primary diagnosis of osteoarthritis, an intact rotator cuff and bone stock suitable for TSR. Participants in both arms of the trial will receive usual post-operative rehabilitation. We aim to recruit 430 participants from approximately 28 NHS sites across the UK. The primary outcome is the Shoulder Pain and Disability Index (SPADI) at 2 years post-randomisation. Outcomes will be collected at 3, 6, 12, 18 and 24 months after randomisation. Secondary outcomes include the pain and function subscales of the SPADI, the Oxford Shoulder Score, health-related quality of life (EQ-5D-5L), complications, range of movement and strength, revisions and mortality. The between-group difference in the primary outcome will be derived from a constrained longitudinal data analysis model. We will also undertake a full health economic evaluation and conduct qualitative interviews to explore perceptions of acceptability of the two types of TSR and experiences of recovery with a sample of participants.
Ethics committee approval for this trial was obtained (London - Queen Square Research Ethics Committee, Rec Reference 22/LO/0617) on 4 October 2022. The results of the main trial will be submitted for publication in a peer-reviewed journal and using other professional and media outlets.
Asthma is a chronic respiratory disorder requiring ongoing medical management. This ecological study investigated the spatial and temporal patterns of notification rates for asthma from clinic visits and hospital discharges and identified demographic, meteorological and environmental factors that drive asthma in Bhutan.
Monthly numbers of asthma notifications from 2016 to 2022 were obtained from the Bhutan Ministry of Health. Climatic variables (rainfall, relative humidity, minimum and maximum temperature) were obtained from the National Centre for Hydrology and Meteorology, Bhutan. The Normalised Difference Vegetation Index (NDVI) and surface particulate matter (PM2.5) were extracted from open sources. A multivariable zero-inflated Poisson regression (ZIP) model was developed in a Bayesian framework to quantify the relationship between risk of asthma and sociodemographic and environmental correlates, while also identifying the underlying spatial structure of the data.
There were 12 696 asthma notifications, with an annual average prevalence of 244/100 000 population between 2016 and 2022. In ZIP analysis, asthma notifications were 3.4 times (relative risk (RR)=3.39; 95% credible interval (CrI) 3.047 to 3.773) more likely in individuals aged >14 years than those aged ≤14 years, and 43% (RR=1.43; 95% CrI 36.5% to 49.2%) more likely for females than males. Asthma notification increased by 0.8% (RR=1.008, 95% CrI 0.2% to 1.5%) for every 10 cm increase in rainfall, and 1.7% (RR=1.017; 95% CrI 1.2% to 2.3%) for a 1°C increase in maximum temperature. An increase in one unit of NDVI and 10 µg/m3 PM2.5 was associated with 27.3% (RR=1.273; 95% CrI 8.7% to 49.2%), and 2.0% (RR=1.02; 95% CrI 1.0% to 4.0%) increase in asthma notification, respectively. The high-risk spatial clusters were identified in the south and southeastern regions of Bhutan, after accounting for covariates.
Environmental risk factors and spatial clusters of asthma notifications were identified. Identification of spatial clusters and environmental risk factors can help develop targeted interventions that maximise impact of limited public health resources for controlling asthma in Bhutan.
Monitoring systems exist for clinical research transparency in high-income countries, but systematic assessment of these practices in global health (GH) research (GHR) is limited. We evaluated methods for monitoring GHR transparency and engagement.
Cross-sectional study.
Three sources were used: (a) ClinicalTrials.gov, (b) publications from 20 journals with ‘international’ or ‘global’ in the title and (c) outputs from selected GH funder websites.
From ClinicalTrials.gov, we selected 200 interventional trials on maternal health and tuberculosis (2008–2019), ensuring two-thirds were from low- and middle-income countries (LMIC). From journals, we included 200 trial publications (2011–2023). From funder websites, we included outputs with sufficient metadata to track trial registration and reporting.
Trials were extracted independently by two reviewers for result publications; journal articles were screened to confirm whether they reported trial results. Across all sources, we assessed registration timing, result reporting, open access and stakeholder engagement.
For 200 trials, 37% were prospectively registered, 65% published results in journals and 15% reported summary results in ClinicalTrials.gov. Only 34% reported results in any format within 24 months of completion. Of 200 publications, 72% were freely accessible, and 23% of the 100-article subsample included stakeholder engagement statements. The funder website sample yielded insufficient metadata for analysis.
Monitoring GHR is feasible using registries and journals, though funder websites provide limited tracking. While open-access rates are encouraging, timely reporting and engagement documentation remain weak. These results highlight opportunities for developing GHR-specific monitoring approaches through collaborative efforts among global stakeholders.
To investigate the efficacy of two volumes of acute isometric wall squat exercise on pain sensitivity (primary outcome: pressure pain threshold (PPT)) and intensity (secondary outcome) in adults with knee osteoarthritis.
A parallel-group randomised controlled trial.
Outpatient physiotherapy clinics at hospitals in Saudi Arabia.
Participants (n = 90; mean (SD) age 49.0 (13.0) years) with chronic knee osteoarthritis, diagnosed by a specialist orthopaedic physician using radiographic evidence and clinical judgement, were recruited via two tertiary hospitals in Saudi Arabia.
Participants were stratified by sex and randomly allocated to one of three groups: isometric single-repetition wall-squat (ISO-SR; one repetition of a 3-min wall squat or to volitional fatigue at a 100° knee joint angle), isometric multiple-repetition wall-squat (ISO-MR; three repetitions of the same intervention) and control (quiet sitting for 7 min).
PPT was measured at the calf (primary site of interest), lumbar spine and forearm using a pressure algometer. Pain intensity was assessed using a visual analogue scale. Primary analyses compared changes between intervention and control groups. All participants were included in the ITT analysis.
The ISO-MR group had higher mean PPT ratings immediately postintervention in the calf (mean difference=9.4 (95% CI 5.6 to 13.2), p
Both the ISO-SR and ISO-MR exercises to volitional fatigue reduced pain sensitivity in patients with knee osteoarthritis. Neither exercise volume changed clinical pain intensity.
