Objective: To evaluate the performance of Ghana's environmental surveillance (ES) system for poliovirus (PV) detection from 2018 to 2022 using standardised indicators developed by the WHO and the US Centers for Disease Control and Prevention.

Design: A retrospective performance evaluation using 10 key indicators benchmarked against global targets for PV surveillance.

Setting: Seven regions across Ghana, participating in the national ES programme implemented under the Global Polio Eradication Initiative.

Surveillance coverage: Wastewater sampling was conducted at designated ES sites, supported by field collection teams and laboratory personnel responsible for sample acquisition, processing and reporting of PV detection results.

Outcome measures: Detection rates of PV and non-polio enteroviruses (NPEVs), timeliness of sample collection and reporting, data quality and system stability.

Results: A total of 738 wastewater samples were collected. The system demonstrated high sensitivity, detecting circulating vaccine-derived PV type 2 in 51 (6.9%) of samples, Sabin PV types 1 and 3 in 61 (9.5%) and 114 (17.8%), respectively, and NPEVs in 491 (66.5%) of samples. Over 80% of samples met the recommended 21-day collection-to-reporting time frame. Data quality exceeded the ≥80% threshold, and workflows remained stable throughout the evaluation period.

Conclusions: Ghana's ES system for PV was found to be flexible, stable and effective in generating high-quality data for early detection and public health response. These findings underscore the system's critical role in supporting polio eradication efforts and highlight its potential as a model for surveillance in similar settings.

Introduction: Postoperative pain is common, with approximately one-third of surgical patients experiencing severe acute pain and 10-20% developing chronic post-surgical pain (CPSP). Evidence shows that female patients are at higher risk of pain after sex non-specific surgery, thus sex- or gender-specific differences in pain treatment efficacy with potential consequences for perioperative pain management are to be expected. Considering the clinical and societal burden of poorly managed postoperative pain, the GEPard project comprises two systematic reviews, GEPard 1: sex- and/or gender-specific differences in efficacy of perioperative pain management for certain (major) surgical procedures in adult patients; and GEPard 2: sex- and/or gender-specific differences in the dosing, efficacy and adverse effects of the most common systemic perioperative non-opioid- and co-analgesics across all sex non-specific surgical procedures in adult patients.

Methods and analysis: The reviews will be conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook. MEDLINE, Embase, Cochrane Library, Web of Science, Scopus, ClinicalTrials.gov and PsycINFO will be searched. We will include randomised controlled trials (RCTs) and systematic reviews/meta-analyses reporting outcomes disaggregated by sex and/or gender in adult surgical patients. For GEPard 1, this applies to selected major surgical procedures; for GEPard 2, to all non-sex-specific surgical procedures. Interventions include regional anaesthesia, systemic analgesics and psychological strategies for GEPard 1 and non-opioid- as well as co-analgesics for GEPard 2. Two reviewers will independently screen and extract the data. Cochrane Risk of Bias Tool 2.0 (RoB 2) and AMSTAR 2 tools will assess study quality. Random-effects or Bayesian meta-analyses will be performed where possible; otherwise, narrative synthesis will be applied. GRADE methodology will assess evidence certainty.

Ethics and dissemination: No ethical approval is required for these reviews. Findings will be disseminated via peer-reviewed publications, patient organisations and professional societies. Data will be shared via Zenodo or Open Science Framework (OSF), following FAIR principles.

Prospero registration number: The systematic review protocols for both reviews have been registered in PROSPERO on 29 August 2025 (Registration-ID: CRD420251121393 (GEPard1), CRD420251121536 (GEPard2).

Introduction: Cardiogenic shock (CS) is a complex syndrome characterised by primary cardiac dysfunction. Despite advances in therapeutic options such as mechanical cardiac support, it remains associated with high mortality. Although previous registries have described heterogeneous populations and outcomes across different centres, contemporary real-world data on management practices remain limited. This gap is particularly evident in low- and middle-income countries, where there is no robust registry that clearly defines the current state of CS management. Therefore, a multicentre registry is needed to better characterise current practices and outcomes. Our study aims to gain insight into current therapeutic trends in Mexico, a low- to middle-income country with a significant cardiovascular disease burden.

Methods and analysis: The Mexican Registry of Cardiogenic Shock is a quality initiative that aims to identify therapeutic trends, demographic characteristics and clinical presentations. It also aims to evaluate outcomes, including mortality and cognitive function at in-hospital and 1-year follow-ups, and to identify areas for improvement in the care process across the broad spectrum of CS.

Ethics and dissemination: Ethical approval for this multicentre study was obtained from the local research ethics committees of all participating institutions. The study results will be disseminated to all participating institutions in the form of summary reports and presentations on completion of the analysis.

Objectives: To identify behavioural and household factors associated with poor oral hygiene among Japanese kindergarten children in a population with high health awareness, using the Debris Index-Simplified (DI-S) as a clinical proxy for early oral hygiene deterioration.

Design: Cross-sectional study.

Setting: Seven kindergartens in Sapporo city, Japan.

Participants: Of the 1229 kindergarten children invited, 871 provided parental consent (consent rate: 70.9%). Among them, 675 children aged 1-6 years who completed both the questionnaire and oral examination (completion rate: 54.9%). Most post-consent losses were due to logistical and staffing constraints. Children were stratified into ≤3 year and ≥4 year academic classes.

Primary and secondary outcome measures: The primary outcome was oral hygiene status based on the DI-S scores (categorised as good (DI-S=0) or poor (DI-S>0). The secondary outcome was the presence of dental caries, defined as decayed, missing and filled primary teeth: dmft≥1. Multivariable logistic regression was used to estimate associations between poor oral hygiene and behavioural and household factors.

Results: Among the 675 children, 168 children (24.9%) exhibited poor oral hygiene (DI-S>0) and 89 children (13.2%) had dental caries (dmft≥1). In multivariable analysis adjusted for demographic, dental and dietary variables, poor oral hygiene was significantly associated with being from a multiple-child household (OR 1.67, 95% CI 1.16 to 2.42) and irregular juice consumption (OR 1.60, 95% CI 1.07 to 2.38). Age-stratified analysis revealed that these associations persisted among those in the ≥4 year class, with additional significance for infrequent tooth brushing (<2 times/day; OR 1.81, 95%CI 1.00 to 3.26). Sensitivity analysis using dmft revealed that the significant associations differed: male sex, age and irregular snacking were significant, while household composition and juice consumption were not.

Conclusions: In a high health awareness Japanese preschool population, poor oral hygiene was independently associated with household composition and juice consumption, rather than traditional dental behaviours. These findings suggest the need to broaden preventive strategies beyond routine dental guidance to include family structure and dietary patterns, particularly in low-prevalence settings. Differential associations between DI-S and caries experience emphasise the utility of early clinical indices in oral health promotion.

Introduction: Robotic rehabilitation on locomotion is a new approach in amyotrophic lateral sclerosis (ALS) and previous studies showed its feasibility. In this study, we aim to evaluate safety, patient's experience and efficacy of a gait training programme with the Atalante exoskeleton, compared with usual care, on walking ability, functional capacity and other symptoms associated with ALS.

Methods and analysis: EXALS is a monocentric, prospective, interventional, open trial. 20 slowly progressing patients with gait deficits will be recruited. The study is conducted in three phases, each lasting 6 weeks, following the ABA procedure. Phase B represents the intervention phase, during which patients practise their gait training at a rhythm of three sessions/week, as an add-on to usual care. In the two phases A, patients receive usual care with no additional treatment. An evaluation is planned before, in the middle and at the end of each phase. The primary outcome of the study is safety and tolerability of the Atalante exoskeleton. Secondary outcomes include: participants' subjective impact and experience, attitude and motivation, efficacy and interactivity of the exoskeleton, walking ability, functional capacity, spasticity, balance, postural stability, lower limb muscle strength, quality of life, pain, fatigue, anxiety and depression. Statistical analyses will include descriptive methods for all variables and adverse events. Quantitative outcomes are analysed using repeated-measures ANOVA (analysis of variance) across the seven visits, with post hoc tests applied when appropriate. Nominal outcomes are evaluated using Cochran's Q test with McNemar pairwise comparisons when significant. Associations between variables are examined using Spearman correlation coefficients. Missing data will be replaced using linear interpolation, and sensitivity analyses will be planned. Qualitative interview data are analysed using thematic analysis.

Ethics and dissemination: This study was approved by the French ethics committee CPP Nord-Ouest I (no. 23.02378.000201). Participant data are anonymised and securely stored in the laboratory's database, accessible only to the research team. Results will be disseminated through peer-reviewed journals and conferences.NCT06199284.

Introduction: The objective of this scoping review is to identify and describe factors that affect access to post-sepsis care. Considering the burden faced by sepsis survivors, it is important to understand the facilitators and barriers to accessing post-sepsis care to facilitate the design and implementation of patient-centred and equitable pathways to care.

Methods and analysis: This scoping review will include studies that consider individuals who have experienced sepsis and any factors that may affect access to care, including comorbidities, discharge setting and social determinants of health. A comprehensive search of MEDLINE, Embase, Emcare, HealthSTAR and Scopus will be conducted. The extracted data will be summarised and presented thematically.

Ethics and dissemination: Approval from a research ethics board is not required for this review as it is a synthesis of information from studies where the primary investigators have already received approval from their respective ethics boards. Once complete, the review will be submitted for publication in a peer-reviewed journal, and the findings will be shared to local and national forums.

Objectives: To describe the prevalence and characteristics of traditional, complementary and integrative medicine (TCIM) practice and product use by the population of the UK providing up-to-date data on the landscape of TCIM use in the UK.

Design, setting and participants: A cross-sectional online survey, administered using the Qualtrics platform, among adults (aged 18 years and over) residing in the UK (England, Wales, Scotland or Northern Ireland). Data were collected between May and October 2024. The 40-item instrument covered four domains: demographics, health status, use of health products and practices, and use of health services. Descriptive statistics were used to summarise survey responses, and χ² tests were applied to assess associations between participant characteristics and TCIM use. Backwards stepwise logistic regression was conducted to identify predictors of TCIM use across four outcome categories (p≤0.05).

Results: The sample (n=1559) was broadly representative of the UK population. Prevalence of any TCIM use over a 12-month period was 65.9% with 19.1% consulting a TCIM practitioner and 63.3% using any TCIM product or practice. Bodywork therapists (massage therapists 9.4%, chiropractors 7.9%, yoga teachers 5.0%) and homeopaths (4.1%) were the most commonly consulted TCIM practitioners and Anthroposophic doctors were the least commonly consulted (2.1%). Among TCIM products, vitamin and mineral supplements were the most commonly used (37.3%) and relaxation or meditation practices were reported by 19.4% of respondents. TCIM users were more likely to be female, identify as Asian or Black, have a chronic disease diagnosis, report good health, possess private health insurance, have a higher education level, be employed (or seeking employment) and sometimes experience financial management difficulties.

Conclusions: There is substantial use of TCIM across the UK adult population and there is a need for more research on integrating TCIM into mainstream healthcare and the National Health Service. Clear strategies are necessary to enhance communication between TCIM and conventional healthcare providers, ensure patient safety and promote person-centred, coordinated models of care.

Objective: This study aimed to determine the prevalence and factors associated with pre-diabetes and undiagnosed type 2 diabetes (UDD) in Cambodia.

Design: This analysis used data from the WHO World Health Survey Plus, which was collected using a cross-sectional design with a GIS-based, three-stage sampling approach. Multiple logistic regression was used to identify key associated factors, based on a significance level of p<0.05.

Setting: Data were collected from all 25 provinces in Cambodia between 12 March 2023 and 31 May 2023.

Participants: 4427 individuals aged 18 years or older, residing in the selected household for at least 6 months in the past year.

Primary outcome measures: Pre-diabetes (Haemoglobin A1c (HbA1c) 5.7%-6.4%) and UDD (HbA1c≥6.5%), without prior knowledge of having type 2 diabetes (T2D).

Results: The weighted prevalences of pre-diabetes and UDD were 26.4% (95% CI 24.0% to 29.0%) and 9.3% (95% CI 7.9% to 11.0%). Pre-diabetes prevalence was higher in urban areas compared with rural areas (adjusted OR, aOR=1.2, 95% CI 1.0 to 1.4), males (aOR=1.7, 95% CI 1.3 to 2.3), individuals aged 40-49 (aOR=1.8, 95% CI 1.4 to 2.4), individuals aged 50+ years group (aOR=2.9, 95% CI 2.3 to 3.6) compared with the 18-39 years group, overweight individuals (aOR=1.7, 95% CI 1.4 to 2.0), obese (aOR=2.1, 95% CI 1.5 to 3.0) and those with elevated total triglycerides (aOR=1.3, 95% CI 1.1 to 1.5). Similar risk factors were identified for UDD, with the addition of hypertension (aOR=1.6, 95% CI 1.3 to 2.0) and high waist circumference (aOR=2.0, 95% CI 1.5 to 2.7).

Conclusions: The high prevalence of pre-diabetes and UDD in Cambodia is a pressing public health concern. Urgent and intensive interventions are needed to effectively prevent and manage T2D, particularly among urban residents, older persons and individuals with metabolic risk factors.

Objective: Acute kidney injury (AKI) is a significant challenge in hospital settings, and accurately differentiating between intrinsic and prerenal AKI is crucial for effective management. The fractional excretion of urea (FEUN) has been proposed as a potential biomarker for this purpose, offering an alternative to traditional markers such as fractional excretion of sodium. This study aimed to assess the diagnostic accuracy of FEUN for differentiating intrinsic from prerenal AKI in hospitalised patients.

Designs: We conducted a systematic review and bivariate random effects meta-analysis of diagnostic accuracy studies. The study followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Data sources: PubMed, Embase and Cochrane databases were searched from inception to 1 November 2023.

Eligibility criteria for selecting studies: We included observational studies that focused on patient with AKI and reported FEUN data sufficient to reconstruct a complete 2 × 2 contingency table (true positives, true negatives, false positives and false negatives) for evaluating its diagnostic accuracy.

Data extraction and synthesis: Two reviewers extracted data, assessed risk of bias with Quality Assessment of Diagnostic Accuracy Studies-2 and graded certainty of evidence using the GRADE approach. Pooled sensitivity, specificity, positive and negative likelihood ratios, and the area under the summary receiver operating characteristic curve (SROC) were calculated; heterogeneity was measured with I². A prespecified subgroup restricted to patients receiving diuretics served as a sensitivity analysis.

Results: 12 studies involving 1240 patients were included, with an overall occurrence rate of intrinsic AKI of 38.8%. FEUN had a pooled sensitivity of 0.74 (95% CI 0.60 to 0.84) and specificity of 0.78 (95% CI 0.66 to 0.87), with positive predictive value and negative predictive value of 0.76 (95% CI 0.68 to 0.83) and 0.74 (95% CI 0.66 to 0.81), respectively. The SROC curve showed a pooled diagnostic accuracy of 0.83. Heterogeneity was substantial (I²>90%) for sensitivity and specificity. In a diuretic-only subgroup (six studies) specificity rose to 0.87 and heterogeneity declined (I²=56%). Overall certainty of evidence was low owing to inconsistency.

Conclusions: FEUN is a biomarker with moderate diagnostic accuracy for differentiating between intrinsic and prerenal AKI in hospitalised patients. Its application could enhance AKI management; however, the high heterogeneity observed in our study highlights the need for further research to evaluate its utility across diverse patient populations and clinical settings.

Prospero registration number: CRD42024496083.

Objective: Long-term healthcare utilisation (HCU) among mothers of infants with neonatal, invasive group B Streptococcus disease (iGBS) remains understudied; identifying these patterns could provide better support for affected families and address the iGBS public health burden.

Design: Cohort study.

Setting: Population of Denmark.

Participants: 1565 mothers of infants with iGBS and 44 976 matched comparators from 1997 through 2021, with follow-up until 2022, using national health and social registry data.

Primary and secondary outcome measures: HCU including primary, inpatient, outpatient, psychiatric and surgical care was evaluated as period prevalence ratio (PPR) and rate ratios compared across three time periods (0-6 years, 7-13 years and 14-20 years) using a modified Poisson regression model and negative binomial regression with 95% CIs.

Results: Mothers of newborns with iGBS had higher PPRs of psychiatric care contacts in the first 0-6 years and 14-20 years following iGBS compared with the comparison cohort (RR_0-61.12 (95% CI 0.93 to 1.35), RR_14-201.24 (95% CI 0.97 to 1.58)). Exposed mothers had similar PPRs of primary, inpatient and outpatient care use as comparators, except for a slightly higher inpatient care use 7-13 years following iGBS. Exposed mothers had higher RRs for primary, inpatient, outpatient and psychiatric care contacts than mothers in the comparison cohort.

Conclusion: Mothers of iGBS-exposed infants had elevated psychiatric healthcare use and increased primary, and outpatient care visits compared with matched comparators, suggesting heightened healthcare needs and psychosocial burden of caregiving up to 20 years post-iGBS.
