In wild birds, the breeding season involves a convergence of metabolically demanding life-history stages, including reproduction, moult, and immune defense. We investigated the relationships between microfilarial infection, moult, redox homeostasis, and plumage quality in breeding male village weavers (Ploceus cucullatus) at the Amurum Forest Reserve, Nigeria. We compared four groups (n = 148 total) sampled within 3 mins post-capture: infected-moulting (IM), infected-non-moulting (IN), non-infected-moulting (NM), and non-infected-non-moulting (NN). Physiological condition was assessed using the erythrocyte glutathione ratio (GSH:GSSG) and circulating glucose, while plumage reflectance traits were integrated into a composite quality axis (PC1). Microfilarial infections were present in 52.0% (n = 77) of individuals; mean parasite intensities were 6.13 ± 0.35 mf/µL (IN) and 6.45 ± 0.41 mf/µL (IM). Physiological indices varied strongly across groups. The GSH:GSSG ratio was reduced in infected birds, indicating altered redox balance (rs = −0.65). Circulating glucose was highest in the infected non-moulting group (IN) but substantially reduced in the infected moulting group (IM). Across physiological and ornamental traits, individuals experiencing both infection and moult (IM group) exhibited the strongest reductions relative to all other groups. However, this pattern reflects a statistically supported Infection × Moult interaction, rather than an untested synergistic or non-linear effect, as evidenced by significant IN vs. IM contrasts in glucose (Table 3; z = 33.43, PAustralian studies investigating parental factors often lack meaningful inclusion of Aboriginal and Torres Strait Islander families, limiting our understanding of current influences on positive developmental trajectories within communities. There is growing recognition of the need for culturally safe and responsive longitudinal research that is co-designed and co-led by the community for the community. An Indigenous-led birth cohort study of Aboriginal and Torres Strait Islander families in Queensland, Australia, has therefore been developed to better understand health across generations.
The Strong Families Study is a co-designed prospective longitudinal birth cohort study that will follow 400 Indigenous families in Queensland from pregnancy until the child reaches 5 years of age. Eligible participants include pregnant individuals (
This study was approved by the Mater Misericordiae Ltd Human Research Ethics Committee (HREC/MML/105191) and ratified by the University of Queensland Human Research Ethics Committee (2025/HE001924). Endorsement letters were secured from partner services at each study site. Findings will be shared with partnering hospitals and funding bodies at conferences and through reports and peer-reviewed publications.
Obsessive-compulsive disorder (OCD) is characterised by obsessive thoughts and compulsive actions. These obsessive-compulsive symptoms (OCS) are subclinical manifestations that do not meet the full diagnostic criteria for OCD and are associated with anxiety, depression and lower quality of life (QoL). Medical students are vulnerable to developing OCS due to stress in medical school. This study assessed OCS prevalence and its association with the mental well-being and QoL of medical students in Egypt.
A nationwide cross-sectional study was conducted across 15 Egyptian medical schools. Using convenience sampling, 1850 students participated by completing a self-administered questionnaire that used validated scales. We assessed OCS with the Obsessive-Compulsive Inventory-Revised (OCI-R) using a screening cut-off of ≥21, QoL with the Quality-of-Life Enjoyment and Satisfaction Questionnaire (Q-LES-QSF), and anxiety and depression with the 4-item Patient Health Questionnaire (PHQ-4). Descriptive statistics and logistic regression were employed.
Clinically significant OCS prevalence among medical students was 51.1%. Significant predictors for OCS included being female (adjusted OR (AOR)=1.25), attending a private university (AOR=1.64), and having personal (AOR=2.05) or combined personal and family history of mental illness (AOR=2.69). OCS presence was associated with a lower QoL score (Q-LES-QSF: 41.00 vs 43.97) and higher psychological distress score (PHQ-4: 5.93 vs 3.57) compared with students without OCS (p
OCS are prevalent among Egyptian medical students, especially females, private university attendees and those with a personal or family history of mental illness. These symptoms are associated with higher psychological distress and a lower QoL. As OCS were identified using a screening cut-off, and given the cross-sectional design, findings should be interpreted cautiously, warranting further longitudinal investigation. Universities should consider implementing mental health support, screening and awareness programmes to address these issues.
Accurately capturing social contact data is essential for developing effective mathematical models to forecast disease trends and evaluate interventions. There are limited population-based data of social contacts in the USA which limits our ability to accurately model infectious disease transmission.
To fill in this gap, we conducted a staggered longitudinal cohort study in metropolitan Atlanta, Georgia, USA. We aimed to characterise contact patterns and examine how they varied by (1) participant demographics, (2) seasonality and (3) self-managed and medically-attended symptoms. Once per month for 6 months, participants reported individual contacts they can name, individual contacts they cannot name and contacts that occurred in group settings. We defined individual contacts as a two-way conversation with five or more words in the physical presence of another person or physical skin-to-skin contact and group contacts as contacts with a group of people with whom participants talked, interacted or shared space. Participants were enrolled on a rolling basis, and data is collected from November 2024 through April 2026. Data analysis will generate age-specific contact matrices using individual contacts and compare contact rates by symptoms. We will also analyse the number and characteristics (eg, indoor/outdoor) of each type of contact. The contact matrices and results will be publicly available for the wider modelling community.
Kaiser Permanente Interregional Institutional Review Board (IRB) reviewed and approved all submitted study documents. An IRB Authorization Agreement was established with the Emory University IRB documenting the roles and responsibilities of each study site. On study completion, de-identified individual level contact data as well as contact matrices and analytical code will be made publicly available on GitHub/Zenodo platform. Study findings will be published in scientific journals and presented at conferences.

Insecticide resistance in malaria vectors remains a global public health problem; however, little is known about resistance levels in Osun State, despite relatively high rates of malaria and distribution of insecticide-treated nets in the area. This study evaluates the resistance status of adult female Anopheles gambiae s.l to pyrethroids (permethrin, deltamethrin and alpha-cypermethrin) and an organophosphate (pirimiphos-methyl) insecticides and knockdown resistant (KDR) gene detection in six locations (Ido-Osun, Ipetumodu, Inisa, Ejigbo, Ijebu-Jesha and Ila) across the three senatorial districts in Osun State, Nigeria. Larval sampling was done between 0700hr and 1100hrs weekly between January and December 2022. Collected larvae were reared to the adult stage in the Department of Animal and Environmental Biology laboratory of Osun State University, Osogbo, Nigeria and then identified morphologically using morphological keys. Insecticide bioassay was conducted with permethrin (0.75%), deltamethrin (0.05%), alpha-cypermethrin (0.05%) and pirimiphos-methyl (0.25%) using WHO procedure. The mosquitoes were subjected to molecular analysis to detect the KDR gene. Pirimiphos-methyl showed significantly higher knockdown at 60 minutes (KD60) and achieved 100% mortality compared with the pyrethroids tested (p Anopheles gambiae s.l as compared to pyrethroids. Therefore, there is a need to intensify insecticide resistance surveillance of Anopheles in Osun State to plan indoor residual spraying with pirimiphos-methyl and explore the use of PBO or dual active ingredient insecticides treated nets (ITNs) to address the potential impacts of pyrethroid resistance.This scoping review explores the environmental impact of nursing interventions in acute care settings, focusing on waste reduction, energy consumption, and carbon emissions, while identifying nurse-led sustainability practices, assessment frameworks, and implementation barriers/enablers.
Guided by Arksey and O'Malley's framework and reported per PRISMA-ScR guidelines.
Data Sources: PubMed, CINAHL, Scopus, and Google Scholar were searched for peer-reviewed, English-language studies published between 2020 and 2025. Review Methods: A five-stage process was employed: (1) research question formulation, (2) comprehensive literature search, (3) study selection using the Population–Phenomenon–Context (PPC) framework, (4) data charting via a structured extraction form, and (5) thematic synthesis. Methodological quality was appraised using Joanna Briggs Institute (JBI) tools.
Of 400 identified records, 25 met inclusion criteria. Findings show nurses reduce environmental impact through reusable linen use (e.g., 496 kg/year ICU waste reduction), energy-efficient equipment, and improved waste segregation. However, time constraints, limited resources, and inadequate sustainability training impede consistent implementation. Awareness among nurses and students is moderate but rarely translates into practice.
Nursing interventions hold significant potential to reduce healthcare's environmental footprint. Embedding sustainability competencies into curricula and reinforcing them with institutional policies and leadership support are essential.
This review informs nurses and clinical leaders that sustainable practices—such as switching to reusable linens and optimizing energy use—are both feasible and impactful in acute care. It provides actionable evidence for reducing waste and carbon emissions while maintaining patient safety, supporting the integration of environmental stewardship into daily nursing practice. Findings from this review highlight the measurable environmental benefits of nurse-led sustainability interventions, such as waste reduction and energy conservation in ICUs. The evidence supports updating nursing curricula, clinical guidelines, and hospital policies to equip nurses with the knowledge and tools needed to lead sustainability efforts, thereby reducing healthcare's carbon footprint without compromising care quality.
To explore factors affecting research engagement among Nurses, Midwives and Allied Health Professionals (NMAHPs) in England by examining perceptions of research capacity at organisational, team and individual levels.
Research engagement strongly correlates with improved care quality. However, NMAHPs face persistent participation barriers compared to medical colleagues, limiting the development of a multi-professional research workforce.
National descriptive cross-sectional study using a validated survey tool.
Data from NMAHPs across England were collected using the validated Research Capacity and Culture tool. Quantitative data were analysed descriptively and inferentially; qualitative free-text responses were evaluated thematically.
Perceived capacity was moderate organisationally and in teams. Organisational strengths included promoting evidence-based practice (68.7%) and leadership support (61.6%). Teams offered moderate research opportunities (58.6%) but limited mentorship (47.9%). Individually, participants showed competence in literature review (69.5%) and data collection (63.4%) but required support for funding acquisition (43.8%) and publication (50.0%). Qualitatively, research was a highly valued aspect of professional identity, though participation is severely constrained by structural conditions, including extreme resource pressures, unclear career pathways, and professional inequality.
Despite strong motivation for evidence-based practice, significant structural barriers restrict NMAHP research engagement. Strengthening capacity demands coordinated action across clinical and policy systems, ensuring equitable access to protected time, mentorship, and vital research infrastructure.
Supporting NMAHPs in research enhances evidence-informed decisions and service innovation. Embedding research into everyday clinical work, rather than viewing it as optional, builds a sustainable multi-professional culture.
This survey pinpoints the specific factors most strongly influencing NMAHP research engagement. It provides healthcare leaders actionable insights to build sustainable research infrastructure and inclusive clinical academic pathways.
This study adhered to STROBE guidelines for cross-sectional research.

Burns are a major cause of morbidity in Yemen, and their prevention relies heavily on community knowledge and safe practices. Understanding gaps in awareness and behaviour is essential for designing effective interventions. This study assessed the knowledge, attitudes and practices (KAP) regarding burn prevention and first aid among a Yemeni community. A cross-sectional survey was conducted among 380 participants using a structured questionnaire distributed via social media and community networks. Data were collected on demographics, educational level, occupation, residential area and KAP related to household, electrical and chemical burns. Associations between participant characteristics and burn-related KAPs were analysed. Participants were predominantly female (63.7%), aged 15–45 years (79.8%), urban residents (92.9%) and university-educated (82.1%). Healthcare workers comprised 50.8% of respondents. Knowledge of burn prevention and first aid was highest among university-educated and healthcare participants, with 84.6% correctly identifying initial burn management. Unsafe practices, such as applying honey or toothpaste and improper handling of chemical or electrical injuries, were more common among less-educated, rural and nonhealthcare respondents. Urban participants demonstrated better preventive practices, while cultural reliance on traditional remedies persisted across all groups. Among predominantly urban and educated populations in Yemen, knowledge and attitudes toward burn prevention and first aid are generally favourable; however, gaps persist, particularly in rural and less-educated communities. Cultural practices and misconceptions continue to limit optimal care. These findings underscore the urgent need for culturally sensitive, literacy-appropriate, community-based interventions to improve burn prevention, first aid practices and equitable health outcomes.
Nursing leadership is crucial for empowering nurses to excel in their roles. Among various leadership approaches, strengths-based leadership is particularly effective in harnessing staff potential to meet current workplace demands. However, the benefits of this leadership style on nurses' work ability remain underexplored, and the underlying mechanisms driving this relationship have not been thoroughly investigated.
Based on the Self-Determination Theory and the Self-Validation Theory, this study aimed to examine: (1) whether nurse managers' strengths-based leadership (as perceived by bedside nurses) could foster nurses' work ability, and (2) the mediating role of a growth mindset in this association.
Structural equation modeling in AMOS software was conducted, analyzing cross-sectional data from 209 bedside nurses using the Strengths-Based Leadership Scale, the Growth Mindset Scale, and the Work Ability–Personal Radar Scale. Participants were recruited via convenience sampling from October to December 2024 across three tertiary public hospitals in Cairo and Mansoura, Egypt.
Strengths-based leadership was significantly associated with nurses' work ability. Growth mindset of nurses partially mediated the positive association between strengths-based leadership and their work ability.
This study emphasizes the role of strengths-based leadership, an underexplored yet significant leadership style in the nursing literature. It is the first study to examine the effect of strengths-based leadership on nurses' work ability, mediated by a growth mindset.

BackgroundGenerative artificial intelligence (AI) tools such as ChatGPT are increasingly used in academic research, yet evidence on postgraduate students’ perceptions remains limited in non-Western and health-professional contexts. Understanding how students perceive AI’s benefits, risks, and ethical implications is essential for informing institutional research policies.
MethodsThis cross-sectional case study surveyed 267 master’s students enrolled in nursing and health profession programs at Northern Border University in Arar, Saudi Arabia. Data were collected between October 1 and November 15, 2025, using a validated 54-item questionnaire that assessed perceived benefits, perceived risks, privacy concerns, mistrust in AI, performance anxiety, social bias, regulatory matters, liability issues, and intention to adopt AI tools. Multiple linear regression with heteroscedasticity-robust (HC3) standard errors was used to identify predictors of AI adoption intention.
ResultsMost participants (85.0%) reported prior use of AI tools, predominantly ChatGPT. Perceived benefits were the strongest predictor of intention to adopt AI for research purposes (β = 0.588, p 2 = 0.560).
ConclusionsAmong nursing and health profession master’s students at a regional Saudi university, findings indicate pragmatic optimism toward AI integration in academic research, driven primarily by perceived benefits alongside heightened ethical and privacy awareness. Privacy concerns appear to reflect critical literacy rather than barriers to adoption.
To evaluate the association between non-steroidal anti-inflammatory drugs (NSAIDs) and miscarriage, which remains elusive in the actual literature, using modelling approaches to mitigate time-related bias.
Nationwide, population-based retrospective cohort study.
The study used data from the French National Mother-Child Register (EPI-MERES), developed from the French National Health Data System containing the health information (hospital admissions, drug dispensing, comorbidities, etc.) of about 99% French population.
4 857 907 pregnancies ended in a live birth, a stillbirth or a miscarriage from 2013 to 2019.
Exposure to NSAIDs from 2 weeks before conception to the 20th week of pregnancy.
Miscarriage (ie, spontaneous abortion before the 20th week of pregnancy) from the sixth week of pregnancy. The Cox regression with a time-dependent exposure that incorporated a 3-day lag was used to estimate HRs and their 95% CIs adjusted for maternal characteristics. The 3-day lag period allows for addressing protopathic bias.
In total, there were 163 666 (3,37%) miscarriage cases, and 349 294 (7.19%) pregnancies were exposed to NSAIDs. Unexposed pregnancies were used as the reference category in all analyses. In the main analysis, exposure to NSAIDs increased the risk of miscarriage (HR, 1.83; 95% CI 1.81 to 1.86). The effect of individual drugs was heterogeneous, with 7 of the 19 drugs evaluated shown to increase the risk (flurbiprofen had the highest risk (HR, 3.28; 95% CI 3.15 to 3.41) and naproxen the lowest (HR, 1.09; 95% CI 1.01 to 1.18)). In the sensitivity analyses, increasing the lag time decreased the estimated HR (from HR, 2.25; 95% CI 2.21 to 2.28 with no lag to HR, 1.56; 95% CI 1.54 to 1.59 with a 7-day lag). Overall, the risk of miscarriage remained statistically significant in all the analyses.
Our study found that early exposure to NSAIDs could increase the risk of miscarriage. This finding contributes to the body of evidence on their safety profile and may help inform future recommendations for their use in pregnant women.
This study examined the interplay among spirituality, self-efficacy and resilience in this context.
A cross-sectional study.
A total of 178 parents of children newly diagnosed with diabetes mellitus; the instruments used for data collection were the Parental Self-Efficacy Scale for Diabetes Management, The Arabic version of The Walsh Family Resilience Questionnaire and the Spiritual Perspective Scale.
Self-efficacy had a significant positive direct effect on family resilience. Spirituality also had a significant positive direct effect on family resilience. Additionally, self-efficacy had a significant positive indirect effect on family resilience through its effect on spirituality.
The findings underscore the impact of spirituality and self-efficacy on a family resilience.
Nurses should prioritise self-care and personal reflection to enhance their spiritual well-being. This can help them better understand and empathise with their patients' spiritual needs, allowing for more effective and compassionate care.
Upon the initial diagnosis of diabetes in a child, parents undergo a profound emotional and psychological upheaval. They are faced with the daunting task of managing their child's condition while also coping with their feelings of distress, uncertainty and fear. Amidst these challenges, factors such as self-efficacy and resilience play pivotal roles in determining how parents adapt to and navigate this new reality.
Nurses can use spiritual care to give parents a sense of meaning, purpose and hope, bolstering their self-efficacy and resilience.
The relevant reporting method has been adhered to, that is, STROBE.
In our research, data collection is assisted by nurses working in community-based settings.
To examine the impact of delays in intensive care unit (ICU) admission on patient outcomes, specifically clinical deterioration and mortality among patients transferred from the emergency department (ED) or general wards following acute deterioration in an Australian public hospital.
This prospective cohort study was conducted over a 12-month period (15 April 2022–14 April 2023) in a 209-bed regional hospital. It included adult patients (aged ≥ 18 years) admitted to the ICU from ED or general wards following acute deterioration. Primary outcomes measured were duration of delay in ICU admission, ICU and hospital mortality and changes in Sequential Organ Failure Assessment (SOFA) scores over time to assess organ dysfunction and progression.
A total of 403 patients were included. Of these, 276 (68.5%) experienced delays in ICU admission, ranging from 25 min to 347.25 h (median: 7.13 h). Delayed ICU admission was associated with increased mortality. Each one-point increase in the highest recorded SOFA score was linked to a 7.5% rise in mortality odds, while each one-point increase in the initial or 24-h SOFA score corresponded to a 6.8% increase.
Delayed ICU admission was significantly associated with increased mortality, particularly in patients with elevated SOFA scores, indicating worsening organ dysfunction and clinical instability.
These findings highlight the urgent need for improved triage systems, early warning protocols and streamlined escalation pathways to expedite ICU transfers for deteriorating patients. Timely intervention is essential to reduce harm and improve outcomes.
This study reinforces the clinical risks of delayed ICU admission and supports timely escalation of care in emergency and ward settings across Australian public hospitals.
Conducted in accordance with STROBE guidelines.
No direct patient or public involvement. The study used routinely collected clinical data to evaluate systemic and clinical outcomes.
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.
Chronic kidney disease (CKD) is a significant public health problem that requires effective preventive and conservative methods to limit morbidity and death.
This study aims to give clinical practice an evidence-based basis for the clinical practice of healthcare professionals by methodically looking for the best available data on conservative strategies and CKD prevention in high-risk and early-stage patients.
The 6S evidence resource model was followed and states that evidence retrieval was done top-down, gathering necessary studies from January 2014 to July 30, 2024. Databases searched included BMJ Best Practice, DynaMed, NICE, GIN, SIGN, JBI Evidence Synthesis, JBI Evidence Implementation, Cochrane Library, and PubMed. Following the JBI grade of evidence and recommendation methodology, two reviewers independently examined and assessed the literature, extracting and summarizing evidence.
Seventy-nine publications were identified: 18 guidelines, 1 randomized controlled trial, 2 expert consensus statements, 36 evidence summaries, and 22 systematic reviews and meta-analyses. Key findings were summarized across eight aspects: risk assessment and early detection, risk factors and prevention of genetic factors, management of diabetic nephrology, impact of bariatric surgery on preventing CKD, screening and diagnosis, treatment and prevention strategies, lifestyle modifications, and CKD prevention.
This study summarized the best evidence for preventing CKD from eight aspects, which can help clinical or community medical professionals develop and apply CKD preventive strategies for high-risk groups and early-stage patients. By using these evidence-based strategies, healthcare professionals can reduce the incidence and progression of CKD, leading to fewer hospitalizations, improved kidney function preservation, and enhanced long-term survival and quality of life for patients. Future research should address identified gaps and explore the implementation of these strategies in diverse clinical settings.
Older adults face growing risks of depression and anxiety, yet stigma, comorbidities, cost, and limited access impede receipt of conventional care. Digital mental health interventions (DMHIs), including immersive virtual reality (VR), exergaming, and mobile apps, may reduce these barriers.
To evaluate the efficacy of DMHIs in reducing depressive and anxiety symptoms among adults aged ≥ 50 years.
We conducted a PRISMA adherent systematic review and meta-analysis of randomized controlled trials. Interventions included immersive VR, exergaming/physical digital platforms, mobile applications, and digital cognitive training. Standardized mean differences (SMDs) were pooled with random effects models; heterogeneity was assessed with I 2.
Nineteen RCTs (n = 718; mean ages 50.9–84.7 years) met inclusion criteria. Across studies, DMHIs significantly reduced depressive symptoms (SMD = −0.656, 95% CI = −0.932 to −0.380; p < 0.001) and anxiety symptoms (SMD = −0.559, 95% CI = −0.740 to −0.380; p < 0.0001). Immersive and physically engaging modalities (e.g., VR, exergaming) outperformed app-based approaches. Heterogeneity ranged from moderate to high (I 2 ≈ 69.6%–97%).
Offer DMHIs: especially VR or exergaming when access to in-person therapy is limited or as an adjunct to usual care. Provide brief onboarding and, when feasible, caregiver support to boost adherence and confidence with technology. Select or configure age-friendly interfaces (e.g., large fonts, simple navigation) to address common usability barriers. Integrate DMHIs into stepped-care or rehabilitation pathways and monitor outcomes with validated tools (e.g., GDS, STAI). Address equity by supplying devices/connectivity solutions and consider cost-effectiveness and long-term engagement in implementation plans.

The Infant Gut Bacterial Study in Nigeria (INBUGS-NG) investigates how delivery mode, antibiotic exposure, feeding practices and environmental factors shape gut microbiome development and acquisition of antibiotic resistance genes (ARGs) during the first year of life in northern Nigeria.
Between February and July 2024, 90 mother–infant dyads were enrolled at a tertiary hospital in Kano city, Nigeria. This was a prospective longitudinal cohort with follow-ups at 10 scheduled time points: days 0, 1, 3, 5, 7, 14, 28, 90, 180 and 365. We also intensified stool sampling after infant antibiotic administration, enabling dense early-life sampling. To date, the cohort has contributed 480 infant stool samples, 232 maternal rectal swabs, 254 breast milk samples and 806 environmental samples (total 1772). In parallel, socio-demographic, clinical and cultural data were collected using Research Electronic Data Capture (REDCap) and household visit diaries.
Baseline data show that 84/90 mothers (93.3%) received postpartum antibiotics, and 26/90 infants (28.9%) received antibiotics within the first 3 months of life. Only 8% of infants were exclusively breastfed, with early water supplementation common. Caesarean deliveries accounted for 25% of births, and the mean gestational age was 38.5 weeks. Across the cohort, high retention was achieved, and the study has generated a unique long-read metagenomic resource from an African infant population, with analyses ongoing.
Shotgun long-read metagenomic sequencing (Oxford Nanopore) will enable strain-level and plasmid-level profiling of microbial communities and ARGs. Planned analyses include associations between early-life exposures and resistome dynamics, as well as cross-cohort comparisons with a parallel study in Pakistan. Follow-up will continue through 12 months.
Poor access to surgical wound swabbing in the community often results in delayed or inappropriate antibiotic prescribing for surgical site infections. This delay can contribute to prolonged wound healing and poor antimicrobial stewardship. Patient self-swabbing at home could improve access to diagnostic testing, but its feasibility and acceptability remain unexplored.
TREASURE is a multicentre, mixed-methods feasibility study. A total of 40 patient participants and 10 staff stakeholders will be included. 40 adult patients undergoing cardiac surgery via median sternotomy will be recruited from Harefield Hospital (n=25) and the Royal Sussex County Hospital (n=15). Eligible participants will receive a coproduced self-swabbing set of instructions and kit at discharge and perform wound swabbing at home within 1–21 days, observed remotely by a researcher via Microsoft Teams. Swabs will be couriered to a central laboratory for bacterial culture with antimicrobial susceptibility testing for pathogens.
The primary feasibility outcome is the proportion of patients successfully completing self-swabbing at home to obtain usable culture swabs with samples received at the laboratory within 24 hours and deemed suitable for processing. Secondary safety and acceptability outcomes include usability of the kit and instructions; patient satisfaction; viability of samples for laboratory analysis; and recruitment and retention rates. A 30-day follow-up will capture wound complications, antibiotic prescribing and healthcare utilisation via patient questionnaires, case note review, general practitioner confirmation and patient interviews. 10 staff stakeholders will be interviewed to inform pathway development.
Quantitative data will be analysed descriptively, with proportions reported alongside 95% CIs. Qualitative data from patients will undergo thematic analysis, and stakeholder interviews will be coded using Normalisation Process Theory. An early health economic model will be developed to explore resource use, costs and proportions of appropriate and timely antibiotic use between current pathways and a proposed pathway, including self-swabbing.
West of Scotland Research Ethics Service has reviewed and approved the study (REC reference: 25/WS/0079). Findings will be disseminated through the study website, a webinar, peer-reviewed publications, conference presentations, patient and public involvement-led activities and engagement with National Health Service (NHS) stakeholders.
