This study aims to assess the feasibility of respondent-driven sampling (RDS) to recruit participants with recent abortion experiences in humanitarian contexts, and describe the composition of the study sample generated with this sampling method.

This was a three-phase mixed-methods community-engaged research study employing an exploratory and explanatory sequential approach. We conducted in-depth interviews, focus group discussions, an interviewer-administered questionnaire on abortion experiences and a health facility assessment.

Bidibidi Refugee Settlement, Uganda and Kakuma Refugee Camp, Kenya from November 2021 to December 2022.

Using RDS, we recruited 600 participants in Kakuma and 601 participants in Bidibidi with recent abortion experiences. In Kakuma, participants were primarily from Burundi, the Democratic Republic of the Congo and South Sudan; participants in Bidibidi were primarily from South Sudan. Most participants in both sites had completed at least some primary school and were not employed.

RDS recruitment dynamics: convergence and bottlenecks on key sociodemographic variables, recruitment and population homophily, reciprocity of social ties, success and experiences recruiting.

There were minor violations of RDS assumptions, particularly regarding assumptions of reciprocity of ties and seed composition independent of sample. In addition, there was a strong tendency of participants to recruit those from the same home country and living within the same camp zone. However, sample proportions for age, home country, marital status, zone of residence and student status reached equilibrium (stabilised) by around 500 participants at each site, and we were able to quickly attain the study sample size.

While the true representativeness of our sample remains unknown, RDS is a practical and effective recruitment method in humanitarian contexts for sensitive topics, particularly for research questions in which no data or sampling frames exist. However, attention to representativeness and community engagement is essential to optimising its application and ensuring success.

To evaluate the association between the stress hyperglycaemia ratio (SHR) and baseline stroke severity in patients with acute ischaemic stroke (AIS) and to investigate whether the relationship is non-linear.

Retrospective cohort study.

A tertiary hospital in Zhejiang Province, China.

1479 consecutive AIS patients admitted within 24 hours of symptom onset between 2016 and 2022.

SHR was calculated as fasting plasma glucose (mmol/L) divided by glycated haemoglobin (HbA1c, %). Stroke severity was assessed by the NIH Stroke Scale (NIHSS) and categorised as mild (NIHSS ≤5) or moderate to severe (NIHSS >5). Associations between SHR and stroke severity were examined using multivariable logistic regression, generalised additive models and threshold effect analysis.

Patients with more severe strokes had significantly higher SHR values (median 0.99 vs 0.94; p

SHR is independently associated with greater stroke severity at admission. Values below 1.3 may reflect heightened metabolic stress and could help inform early risk stratification in AIS management, but their discriminative power is limited and should be interpreted in conjunction with other clinical indicators.

Current guideline-recommended antibiotic treatment durations for ventilator-associated pneumonia (VAP) are largely standardised, with limited consideration of individual patient characteristics, pathogens or clinical context. This one-size-fits-all approach risks both overtreatment—promoting antimicrobial resistance and adverse drug events—as well as undertreatment, increasing the likelihood of pneumonia recurrence and sepsis-related complications. There is a critical need for VAP-specific biomarkers to enable individualised treatment strategies. The Ventilator-associated pneumonia Biomarker Evaluation (VIBE) study aims to identify a dynamic alveolar biomarker signature associated with treatment response, with the goal of informing personalised antibiotic duration in future clinical trials.

VIBE is a prospective, observational, case-cohort study of 125 adult patients with VAP in Michigan Medicine University Hospital intensive care units. Study subjects will undergo non-bronchoscopic bronchoalveolar lavage on the day of VAP diagnosis (Day 1) and then on Days 3 and 5. Alveolar biomarkers (quantitative respiratory culture bioburden, alveolar neutrophil percentage and pathogen genomic load assessed via BioFire FilmArray polymerase chain reaction) will be assessed. An expert panel of intensivists, blinded to biomarker data, will adjudicate each patient’s Day 10 outcome as VAP clinical cure (control) or treatment failure (case). Absolute biomarker levels and mean-fold changes in biomarker levels will be compared between groups. Data will be used to derive a composite temporal alveolar biomarker signature predictive of VAP treatment failure.

Ethical approval was obtained from the University of Michigan Institutional Review Board (IRB #HUM00251780). Informed consent will be obtained from all study participants or their legally authorised representatives. Findings will be disseminated through peer-reviewed publications, conferences and feedback into clinical guidelines committees.

Sickle cell disease (SCD) is due to the mutation of haemoglobin (Hb), from HbA to HbS and characterised by recurrent vaso-occlusive crises (VOC), which can progress to acute chest syndrome (ACS), a leading cause of death in adults with SCD. Hypoxia is a key modifiable factor in the polymerisation of HbS and the pathogenesis of VOC. High-flow nasal oxygen (HFNO) delivers humidified gas at high oxygen concentrations and flow rates: the former may reverse sickling (metabolic effect) to accelerate VOC resolution and prevent ACS, while the latter may reduce the risk of ACS by mitigating hypercapnia and generating positive airway pressure that limits hypoventilation and atelectasis (pulmonary effect). The study hypothesises that HFNO is a safe and effective strategy for treating VOC and preventing secondary ACS, and will assess this using a multi-arm multi-stage (MAMS) trial design.

This is a prospective, multicentre, randomised, open-label controlled trial following an MAMS design with three phases and four arms: one control (low-flow oxygen) and three HFNO intervention arms with varying fraction of inspired oxygen levels (low, intermediate, high). The pilot stage will assess safety and feasibility, using the rate of cardiac and neurological events as the primary endpoint. In the activity stage, arms demonstrating acceptable safety will be compared for efficacy based on the rate of VOC resolution without complications by day 5, allowing selection of the most promising arm. The final efficacy stage will compare the selected HFNO strategy to control, with prevention of secondary ACS by day 14 as the primary endpoint. The study aims to enrol up to 350 VOC episodes in total.

The study has been granted ethical approval (CPP SUD MEDITERRANEE IV). Following the provision of informed consent, patients will be included in the study. The results will be submitted for publication in peer-reviewed journals.

This study aimed to evaluate the cost-effectiveness of integrating nutritional support into India’s National Tuberculosis Elimination Programme (NTEP) using the MUKTI initiative.

Economic evaluation.

Primary data on the cost of delivering healthcare services, out-of-pocket expenditure and health-related quality of life among patients with tuberculosis (TB) were collected from Dhar district of Madhya Pradesh, India.

Integration of nutritional support (MUKTI initiative) into the NTEP of India.

Routine standard of care in the NTEP of India.

Incremental cost per quality-adjusted life year (QALY) gained.

A mathematical model, combining a Markov model and a compartmental susceptible–infected–recovered model, was used to simulate outcomes for patients with pulmonary TB under NTEP and MUKTI protocols. Primary data collected from 2615 patients with TB, supplemented with estimates from published literature, were used to model progression of disease, treatment outcomes and community transmission dynamics over a 2-year time horizon. Health-related quality of life was assessed using the EuroQol 5-Dimension 5-Level scale. Costs to the health system and out-of-pocket expenditures were included. A multivariable probabilistic sensitivity analysis was undertaken to estimate the effect of joint parameter uncertainty. A scenario analysis explored outcomes without considering community transmission. Results are presented based on health-system and abridged societal perspectives.

Over 2 years, patients in the NTEP plus MUKTI programme had higher life years (1.693 vs 1.622) and QALYs (1.357 vs 1.294) than those in NTEP alone, with increased health system costs (11 538 vs 6807 (US$139 vs US$82)). Incremental cost per life year gained and QALY gained were 67 164 (US$809) and 76 306 (US$919), respectively. At the per capita gross domestic product threshold of 161 500 (US$1946) for India, the MUKTI programme had a 99.9% probability of being cost-effective but exceeded the threshold when excluding community transmission.

The findings highlight the potential benefits of a cost-effective, holistic approach that addresses socio-economic determinants such as nutrition. Reduction in community transmission is the driver of cost-effectiveness of nutritional interventions in patients with TB.

Traumatic brain injury (TBI) often causes permanent neurological dysfunction. Although no medication has been validated yet to prevent secondary injury of brain tissue, recent animal studies have reported that perampanel, a glutamine receptor antagonist, could improve the neurological functions of animals with TBI by mitigating the abnormal calcium influx and cell death around the site of primary injury. The present study aims to elucidate the efficacy of perampanel administration in improving the neurological function of patients with TBI.

The perampanel for alleviation of secondary injury in TBI trial is a multicentre, phase-II, open-label randomised controlled trial targeting patients with mild-to-moderate TBI. This trial will include adult TBI patients with a Glasgow Coma Scale score of 9–14 from five tertiary centres. Patients with epilepsy as a comorbidity, delayed presentation of symptoms (>24 hours after injury) or Injury Severity Score of ≥25 will be excluded. The study participants will be randomly assigned to either the perampanel group (2 mg/day) or the control group (fosphenytoin administered at a dose of 15–18 mg/kg/day, followed by 5–7.5 mg/kg/day of fosphenytoin). In both groups, the medication will be initiated within 12 hours of the TBI diagnosis and continued for 7 days. The antiepileptic drugs can be increased, changed or added as necessary if early post-traumatic seizures are observed. The primary outcome is favourable neurological outcome, defined as a Glasgow Outcome Scale Extended score of ≥5 at 90 days after the TBI diagnosis, which will then be compared between the groups through an intention-to-treat analysis.

The present study has been approved by the Certified Review Board of Keio at the principal institution (approval number: N20240004). Written informed consent will be obtained from all participants or their legal representatives. The results will be disseminated via publications and presentations.

Transitions from the emergency department (ED) to home are high-risk periods for medication-related harm. Pharmacist-led interventions during this period may improve medication safety and care continuity, yet co-design approaches to develop such interventions remain underused. The aim of this study is to co-design a pharmacist-led transition of care programme for patients discharged from the ED.

This study will be conducted at a 371-bed secondary-care teaching hospital in Qatar and will follow two sequential phases using qualitative and participatory methods. Phase I will involve focus groups and semistructured interviews with key stakeholders (clinical pharmacists, physicians, nurses and patients or patient representatives). Phase II will consist of an intervention co-design workshop with decision makers (leaders, policymakers and representatives from Phase I). Participants will be recruited using purposive and snowball sampling. Interviews will be audio recorded and transcribed verbatim. Data will be analysed using an inductive-deductive approach, guided by the Theoretical Domains Framework, the Care Transitions Framework and the APEASE (Affordability, Practicability, Effectiveness/cost-effectiveness, Acceptability, Side-effects/safety, Equity) criteria for evaluation of intervention feasibility.

The anticipated outcome is a prototype intervention detailing target recipients, core components, workflow, implementation strategies and supporting tools. This prototype will be pilot-tested to assess feasibility and inform further refinement.

The study was approved by the Medical Research Centre of Hamad Medical Corporation-Qatar (MRC-01-24-699) and Qatar University Institutional Review Board (QU-IRB 009/2025-EM). Written informed consent will be obtained from all study participants prior to participation. Research findings will be disseminated through institutional stakeholder briefings, presentations at national and international scientific conferences and publication in peer-reviewed journals. Patient representatives will contribute throughout the intervention development process.

To explore the feasibility and acceptability of pain management (transcutaneous electrical nerve stimulation (TENS)) and patient education (PE) to increase physical activity in people with peripheral arterial disease and intermittent claudication (IC).

Feasibility randomised controlled trial with embedded process evaluation.

One secondary care UK vascular centre.

56 community-dwelling adults with a history of stable IC and ankle-brachial pressure index ≤0.9 were recruited via claudication clinics.

Participants randomised to 6 weeks of: TENS+PE, TENS, Placebo TENS+PE or Placebo TENS. PE was a 3-hour workshop plus three follow-up phone calls. The TENS machine was worn during walking (TENS: 120 Hz, 200 μs, intensity ‘strong but comfortable’; Placebo TENS: intensity below sensation threshold).

Primary feasibility outcomes included rates of recruitment, retention and adherence. Acceptability of the intervention and trial procedures was explored with semistructured interviews. Measures of walking capacity, walking behaviour, quality of life, disease perception and pain were recorded at baseline, end of intervention (6 weeks) and follow-up (3 months).

56 participants were randomised from 95 who completed baseline screening. Of the 39 excluded, 97% (38/39) had >20% variability in absolute claudication distance. All participants received their allocated intervention. Outcome completion was 91% at 6 weeks and 80% at 3 months. Attendance at group education was 96% with 63% taking follow-up phone calls. Compliance with TENS was 70% according to participant-completed logs. Interviewed participants (n=9) were generally positive about the acceptability of the interventions and trial procedures; however, experience of TENS use was mixed. Some participants were dissatisfied with the size of the device and electrode wires.

The PrEPAID (Pain management and Patient Education for Physical Activity in Intermittent claudication) trial was feasible to run; however, 40% of potential participants were excluded at screening due to issues of research fidelity rather than participant suitability or willingness to participate. A future definitive trial should consider a revised primary outcome measure and smaller wireless TENS machines.

Migrants and refugees with low language proficiency (LLP) in the dominant language of their host country have a higher risk of suffering from certain mental health disorders compared with non-migrant populations. They are also more likely to experience a lack of access to mental healthcare due to language-related and culture-related barriers. As part of the MentalHealth4All project, a digital multilingual communication and information platform was developed to promote access to mental healthcare for LLP migrants and refugees across Europe. This paper describes the study protocol for evaluating the platform in practice, among both health and/or social care providers (HSCPs) and LLP migrants and refugees.

We will conduct a pretest–post-test cross-national survey study to evaluate the platform’s effect evaluation (primary objective) and process evaluation (secondary objective). The primary outcomes (measured at T0, T2 and T3) are four dimensions of access to mental healthcare services: availability, approachability, acceptability and appropriateness of mental healthcare. Secondary outcomes (measured at T2) are: actual usage of the platform (ie, tracking data), perceived ease of use, usefulness of content, comprehensibility of information, attractiveness of content and emotional support. Participants will be recruited from nine European countries: Belgium, Germany, Italy, Lithuania, the Netherlands, Poland, Slovakia, Spain and the UK. Using convenience sampling through professional networks/organisations and key figures, we aim to include at least 52 HSCPs (ie, 6–10 per country) and 260 LLP migrants (ie, 30–35 per country). After completing a pretest questionnaire (T0), participants will be requested to use the platform, and HSCPs will participate in an additional personalised training (T1). Next, participants will fill out a post-test questionnaire (T2) and will be requested to participate in a second post-test questionnaire (T3, about 6–8 weeks after T2) to answer additional questions on their experiences through a brief phone interview (T3 is optional for migrants/refugees).

For all nine countries, the ethical review board of the participating university (hospital) has assessed and approved the protocol. If successful, the MentalHealth4All platform will be made publicly available to help improve access to mental healthcare services, as well as HSCPs’ cultural competencies in delivering such services, for any LLP migrants and refugees across Europe (and beyond). Findings will also be disseminated through peer-reviewed journals and conferences.

Amoxicillin is recommended for children with uncomplicated severe acute malnutrition (SAM). However, some trials have shown no difference in amoxicillin for nutritional recovery in children with SAM compared with placebo. In addition, amoxicillin treatment requires two times per day dosing for 7 days, which may influence adherence. Azithromycin is a broad-spectrum antibiotic that can be provided as a single dose and has reduced mortality in children aged 1–59 months when provided by mass drug administration. The AMOUR trial is designed to assess amoxicillin, azithromycin and placebo as part of outpatient treatment of uncomplicated SAM.

This double-masked randomised controlled trial will enrol 3000 children over 3 years in an individually randomised 1:1:1 allocation to azithromycin, amoxicillin or placebo arms and follow them for 12 months. Children eligible to enrol in the study will be aged 6–59 months and have uncomplicated non-oedematous SAM as defined by weight-for-height Z-score

A qualitative study was undertaken to explore the nature of staffing strategies from the perspectives of nursing, medicine and health disciplines employed in a hospital setting.

Interviews were conducted in six hospitals in Canada between November 2022 and September 2023.

118 healthcare professionals and leaders who experienced changes in staffing strategies participated in this study. Three themes emerged to describe new or adaptive staffing strategies: (1) valuing new roles and teams; (2) being redeployed; and (3) enhancing coverage.

Our study elucidates the staffing strategies that were employed during the COVID-19 pandemic that included creating new and adapting existing roles and teams; redeploying healthcare professionals; and enhancing coverage. Study findings can be used to guide leaders to use a proactive systematic approach to staffing models that includes adaptable and flexible staffing models within local contexts.

Breastfeeding is beneficial to the health of both the mother and infant. Despite recommendations to breastfeed by organisations including the WHO and the American Academy of Pediatrics, rates of breastfeeding remain below public health goals. The Mother and Infant Metabolome and Microbiome (MIMM) study is a prospective cohort study of healthy mother-term infant dyads designed to comprehensively assess the perinatal, maternal, neonatal and infant factors that are associated with breastfeeding outcomes and human milk composition.

MIMM participants were recruited from two medical centres in Boston, Massachusetts, from 2019 to 2023 and are followed for 2 years. Dyads were included if the mother delivered a singleton infant at ≥37 weeks’ gestation, was discharged home 2 and infant gestational age was 39.3 weeks. Approximately 43% of infants were born via caesarean delivery, and 45.5% were female.

MIMM study procedures include longitudinal (1) collections of maternal blood, vaginal swab, stool and milk and infant blood and stool samples and (2) assessments of breastfeeding status, child neurodevelopment and growth and maternal health at birth, 6 weeks and 6, 12, 18 and 24 months. Data collection through 18 months is complete. The overall objective of the MIMM study is to identify potential targets to improve breastfeeding outcomes, human milk composition and ultimately, maternal and child health. Preliminary analyses, reported in conference presentations (with ongoing analyses and results manuscripts pending), have found that (1) mothers with higher levels of stress were less likely to be exclusively breastfeeding their infants at 6 weeks; (2) higher breastfeeding intensity was associated with greater postpartum weight loss at 6 weeks; (3) feeding type was a more relevant predictor of feeding frequency and volume compared with feeding mode; (4) infants who received exclusive human milk had higher food enjoyment compared with those who received any formula; and (5) infants of mothers with obesity had higher average feeding volume per feed.

Data collection for the final 24-month visit is expected to be completed by August 2025. We expect that all sample assays will be completed by December 2025. Findings will continue to be submitted for presentation at scientific conferences, and we expect to publish the first findings from this cohort in manuscript format in 2025.

Research on therapeutic mobility is abundant but the field of cancer has not yet been investigated thoroughly. This scoping review aims to examine the existing evidence on global therapeutic mobility and cancer, providing a comprehensive overview of the subject.

We conducted a scoping review and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodological guidelines. We developed a comprehensive search strategy and discussed it with the research team. We searched for peer-reviewed papers on Medline, Embase, ERIC and American Psychological Association via the Dialogue interface and Google Scholar and CAIRN bibliographic database for peer-reviewed articles. We also included grey literature, such as unpublished work and relevant reports from Érudit. We considered studies that employed quantitative or qualitative methods.

Among the 1615 references initially selected, 767 duplicates were excluded. Then, 849 studies were screened on title and abstract and 800 were excluded as they did not meet inclusion criteria. 49 studies were fully screened and 21 were excluded as they did not meet inclusion criteria based on full-text assessment. Ultimately, 28 references were included in the data synthesis. This scoping review has shown that publications on therapeutic mobilities have multiplied in recent years, with a turning point in 2019. A range of academic disciplines and research methodologies are currently employed to describe them. A significant proportion of fieldwork is concentrated in Asia, Africa, Europe and North America. Despite the heterogeneity of the approaches and fields, there are certain common features that emerge: first, the decision to migrate for healthcare is primarily made by the patient themselves and is perceived by them as being non-choice; second, the family plays a central role at all stages of the migration; and third, the migration has a catastrophic impact in terms of social and financial burden.

In conclusion, this scoping review highlights the underexplored relationship between global therapeutic mobility and cancer, emphasising the need for increased research efforts to understand the global dynamics of cancer care mobility.

Paediatric cervical spine injury (CSI) is uncommon but can have devastating consequences. Many children, however, present to emergency departments (EDs) for the assessment of possible CSI. While imaging can be used to determine the presence of injuries, these tests are not without risks and costs, including exposure to radiation and associated life-time cancer risks. Clinical decision rules (CDRs) to guide imaging decisions exist, although two of the existing rules, the National Emergency X-Radiography Low Risk Criteria and the Canadian C-Spine Rule (CCR), focus on adults and a newly developed paediatric rule from the Pediatric Emergency Care Applied Research Network (PECARN) is yet to be externally validated. This study aims to externally validate these three CDRs in children.

This is a multicentre prospective observational study of children younger than 16 years presenting with possible CSI following blunt trauma to 1 of 14 EDs across Australia, New Zealand and Singapore. Data will be collected on presenting features (history, injury mechanism, physical examination findings) and management (diagnostic imaging, admission, interventions, outcomes). The performance accuracy (sensitivity, specificity, negative and positive predictive values) of three existing CDRs in identifying children with study-defined CSIs and the specific CDR defined outcomes will be determined, along with multiple secondary outcomes including CSI epidemiology, investigations and management of possible CSI.

Ethics approval for the study was received from the Royal Children’s Hospital Melbourne Human Research Ethics Committee in Australia (HREC/69436/RCHM-2020) with additional approvals from the New Zealand Human and Disability Ethics Committee and the SingHealth Centralised Institutional Review Board. Findings will be disseminated through peer-reviewed publications and future management guidelines.

To assess the effects of age, birth cohort, and period on comorbidity rates as well as project their future trends over the next 25 years.

Population-based retrospective observational study.

Record linkage from the population-based healthcare utilisation database of Lombardy, Italy, between 2004 and 2023.

All beneficiaries of the Italian National Health Service (NHS) aged 50–85 years residing in Lombardy. Data were separately analysed for each year from 2004 to 2023, with thus the availability of 20 study populations.

Comorbidities were traced via the medical services provided by the NHS, and the overall quantification was obtained by the Multisource Comorbidity Score, which was developed and validated for the Italian population. The temporal analysis of the 20 yearly temporal comorbidity rates was obtained by the Age-Cohort-Period models. The comorbidities prevalence trends were forecasted from 2025 to 2050.

From 2004 to 2023, the prevalence of comorbidities declined from 46% to 40% in men and from 47% to 42% in women. An increase in prevalence between the ages of 50 and 85 years was observed for both women (from 33% to 63%) and men (from 29% to 67%). A declining prevalence was observed among cohorts born from 1922 to 1970 for both women (by 33%) and men (by 50%). A continued decline in the absolute number and prevalence rate of comorbidities is expected for both women and men until 2050.

The decline in ageing-related comorbidity prevalence over time may persist up to 2050. Improved medical care and public health initiatives benefiting individuals born in more recent years may counterbalance the expected trend of increasing comorbidity prevalence due to population ageing.

Breast cancer is a global public health challenge. It is the most commonly diagnosed cancer and the leading cause of cancer-related death in women. Several inequalities remain among women facing this disease, depending on their country of birth and their sociodemographic characteristics. The SENOVIE study (Therapeutic mobility and breast cancer) aims to understand the life trajectories of women born in France and in sub-Saharan Africa treated for breast cancer in four hospitals in the greater Paris area.

The SENOVIE study is a mixed methods study, combining a quantitative and a qualitative approach. A quantitative retrospective life-event survey is conducted in four hospital centres in the greater Paris area, France, to (1) understand how breast cancer (diagnosis, treatment and possibly reconstruction) impacts the life trajectories of women in many spheres (migration, family life, professional life, financial situation, etc); (2) study the access to healthcare by women living with breast cancer and their determinants; and (3) examine how gender relations may shape breast cancer experience. Women born in France and women born in sub-Saharan Africa are recruited: 1000 women, including 500 per group. In the standardised, face-to-face questionnaire, each dimension of interest is collected year by year from birth until the time of the survey. Clinical and laboratory information is documented with a short medical questionnaire filled out by the medical teams. The qualitative survey is conducted specifically with women born in sub-Saharan Africa who came to France for treatment to better understand their trajectories and the specific obstacles they faced. To analyse the quantitative data collected, descriptive analyses will be used to visualise trajectories (sequence analysis), along with longitudinal analysis methods (survival models and duration models).

The study is conducted in accordance with the Declaration of Helsinki. The French Data Protection Authority (Commission Nationale de l’Informatique et des Libertés, declaration number 2231238) and the Committee for Persons’ Protection East I (Comité de Protection des Personnes Est I, national number 2023-A01311-44) approved it. We will disseminate the findings through scientific publications, policy briefs, conferences and workshops.
