Beta Glucans (β-glucans) are naturally occurring polysaccharides that have positive effects on healing in acute and chronic wounds. This study aimed to identify how β-glucans modulate macrophage polarisation and inflammation to aid the healing response. Flow cytometry was used to assess the effect of β-glucan on human monocytes during differentiation into M0, M1 and M2 macrophages. Subsequently, a murine full-thickness excisional wound healing model was conducted where wounds were treated with either β-glucan hydrogel or vehicle, at the time of wounding. The wounds were analysed to determine the rate of wound closure, the effect on inflammation, and matrix deposition. β-glucan promoted differentiation of monocytes to M0 macrophages but inhibited differentiation of M0 macrophages to pro-inflammatory M1 macrophages with no effect on M2 macrophage formation. In vivo, treatment of excisional wounds with β-glucan hydrogel accelerated healing with an earlier, more resolved inflammatory phase containing greater numbers of M2 macrophages and fewer neutrophils within the wound. No statistically significant effect on matrix deposition was observed. β-glucans modulate macrophage differentiation and accelerate healing in excisional wounds with no adverse effect on matrix formation. β-glucans are a potential therapeutic approach for treatment of hard-to-heal wounds in humans.
Adnexal surgery is one of the most common surgeries performed in women. Minimally invasive methods are on the rise globally as they have been shown to decrease surgical morbidity compared with abdominal surgery. Adnexal surgery by vaginal natural orifice transluminal endoscopic surgery (vNOTES) is the latest innovation. It combines the vaginal approach and endoscopy via the vagina. Large pragmatic randomised controlled trials (RCTs) are lacking comparing outcomes after vNOTES and conventional laparoscopy.
A multicentre pragmatic RCT aiming to recruit 200 women aged 18 years and above undergoing adnexal surgery for benign disease or prophylactic reasons. Patients will be randomised to vNOTES or laparoscopy. Recruitment will start Q4 2025, and the study is estimated to end 2028.
The primary outcome is postoperative pain. Secondary outcomes are units of postoperative opioid and non-opioid analgesics used, perioperative complications, operation time, postoperative complications, readmission, conversion rate and the surgeon’s experience.
The national Swedish ethical board at the main centre, Helsingborg Hospital, Sweden, has given ethical agreement (dated 20 March 2025). Before including patients, all centres will require local or national ethical approval. The results of the study will be published in international peer-reviewed journals.
To identify and compare the digital competence profiles of nurse educators, the background variables associated with profiles, and the self-assessed level of digital competence in four European countries.
A descriptive comparative cross-sectional study.
Data were collected from nurse educators (n = 263) in 36 nursing education organisations in Finland, Malta, Slovakia and Spain. Partitioning around medoids (PAM) clustering was used to identify competence groups, and descriptive and inferential statistics were used to examine the association of nurse educators' background variables.
The clustering analysis resulted in two nurse educator digital competence profile groups: high and moderate. The profiles differed based on completed pedagogical studies and teaching experience, with an emphasis on the high competence profile. Educators in the high competence profile group showed greater interest in using educational technology and self assessed their digital competence at a higher level compared to educators in the moderate competence profile group. Nurse educators' lowest digital competence was in the safe and responsible use of technology, such as knowing copyright laws.
Despite the heterogeneous background of nurse educators, international continuing professional development needs in digital competence are identified. Nurse educators' continuing education should support the utilisation of technology through pedagogical approaches, and educators' competence in the safe and responsible use of technology (e.g., how to protect digital materials) must be enhanced in nursing education organisations.
This study highlights the need to further develop nurse educators' digital competence. Continuing professional development should target preparation in safe and responsible technology use and include pedagogical studies and mentoring from experienced peers.
The STROBE checklist was adhered to in reporting the results.
Each participating educational organisation assigned a contact person to distribute the survey to the nurse educators.
To explore multidisciplinary clinical, academic, policy and governance stakeholders' perceptions of enablers and barriers to implementing designated registered nurse prescribing in Australia, using a systems-thinking approach.
A two-phase explorative study using a systems-thinking lens to investigate complex health-system interdependencies.
Fifty-three participants were recruited from all Australian states and territories, including registered nurses, nurse practitioners, pharmacists, medical practitioners and health-service planners. Phase 1 involved interviews and focus groups conducted between February 2024 and April 2024 (n = 45), analysed using deductive content analysis, guided by the Sustainability of Innovation Framework. Phase 2 was a face-to-face workshop conducted in August 2024 (n = 28), with data from participant discussions and observer field notes analysed inductively and refined through reflexive dialogue. Reflexive analysis of the findings allowed the construction of recommendations for implementation in various healthcare contexts.
In Phase 1, participants representing all Australian jurisdictions and healthcare contexts identified that successful adoption of designated registered nurse prescribing is contingent upon several interrelated system components. These interconnected factors influence each other within the broader healthcare system and serve as the focus for Phase 2.
In Phase 2, participants reported context-specific service models, stakeholder engagement, financial support, clear messaging and workforce/organisational readiness for new models of care and service delivery were recognised as dynamic interrelated elements. Three overarching themes for successful implementation were generated: The Standard—just one piece of the puzzle. Harnessing collective capability. Shared wisdom for success.
National implementation of registered nurse prescribing requires consistent but context-responsive reforms. A systems-thinking approach underscores the need for whole-of-system strategies, acknowledging interdependencies and avoiding rapid, unplanned implementation. This study highlights that sustainable adoption of registered nurse prescribing in Australia depends on recognising system interdependencies and their dynamic nature.
Designated registered nurse prescribing has the potential to improve timely access to medicines and enhance patient-centred care when implemented with whole-of-system support.
This study provides key systems-level recommendations to guide policymakers and healthcare services to successfully implement designated registered nurse prescribing across various settings.
This study highlights key stakeholders' perspectives, providing valuable insights on the essential elements required for the successful adoption of this expanded practice.
Broad systems-level recommendations are offered to guide policymakers and healthcare services to successfully implement designated prescribing across various settings, taking into account the complexity of the healthcare system.

Transient ischaemic attack (TIA) and migraine can generate identical symptoms but have very different short-term risks of stroke. Uncertainty about the diagnosis may lead to missed opportunities to prevent stroke if TIA is treated as migraine, or overtreatment if migraine is treated as TIA. This project aims to define the risk of stroke for people with migrainous symptoms reviewed as suspected TIA and develop a risk assessment tool that could promote standardisation of care.
The project involves two interlinked studies:
(1) Study A: prospective observational cohort study.
Setting: NHS TIA and stroke services.
Population: adults with migrainous symptoms undergoing review for suspected TIA by a TIA/stroke service and the initial specialist clinician symptom-based diagnosis is either possible migraine or possible TIA with migrainous symptoms.
Data collection: baseline clinical characteristics, investigations and treatments. Stroke, TIA and migraine events within 90 days.
Sample size: 2709 participants.
Main analyses: analysis of stroke risk, development of stroke risk prediction model, preparation of visual tools to represent the risk model.
(2) Study B: qualitative co-design study.
Setting and population: clinicians from NHS TIA and stroke services.
Data collection: focus groups/interviews exploring views about the potential role for a risk assessment tool, the most appropriate visualisation for the risk tool and barriers/facilitators for implementation.
Sample size: approximately 16 clinicians.
Analyses: framework approach using the Implementation Research Logic Model.
This study has ethical, Health Research Authority and participating NHS Trust approvals. Dissemination of study results will include presentations at national and international conferences and events, publication in peer-reviewed journals, and plain English summaries for patient/public engagement activities.

ObjectivesWe developed an efficient Research-Ready Data Asset (RRDA) for the Welsh Longitudinal General Practice (WLGP) data within the Secure Anonymised Information Linkage Databank to standardise curation, enhance reproducibility, and facilitate research on primary care trends. Using this, we investigated primary care activity trends during and after the COVID-19 pandemic.
MethodsThe RRDA involves cleaning, curation using GP-registration history, and transforming data into a structured, normalised format to support efficient large-scale queries. A comprehensive clinical code look-up was developed, incorporating official, local, and supplementary categories to enhance event classification. To enable patient-practice interaction analysis, a four-layer approach was developed to capture healthcare providers, access mode, interaction type, and event details. We assessed RRDA coverage, defined as the proportion of residents with shared primary care records, stratified by demographic and geographic factors, using longitudinal binomial Generalised Additive Mixed Models (GAMMs). We categorised GP events into key activity types and summarised averaged daily rates per month per 100,000 people (2000–2024), with trends analysed using negative binomial GAMMs.
ResultsCurating 4.6 billion records for 5.1 million people (1990–2024) revealed significant improvements in data quality and completeness over time, with data retention increased from 40% to 94%, and patient inclusion from 43% to 98%. Use of SNOMED-CT and local codes increased after Read-V2 discontinuation in 2018, while invalid codes declined—reflecting evolving coding practices and improved data quality. WLGP RRDA coverage rose from 35% in 1990 to 86% in 2024, with regional variation but modest demographic differences. From 2000 to 2024, consultation rates rose by 1.9 times, with post-COVID-19 pandemic levels 8% above 2019. Prescription-only activity doubled with little variation associated with the pandemic. Vaccination rates spiked during the pandemic, and remain 1.8 times above pre-pandemic levels. Other less frequent activities were significantly disrupted during the COVID-19 pandemic but recovered to 2019 levels.
ConclusionsThe WLGP RRDA improves the usability of primary care data, supporting timely, scalable analysis of healthcare delivery and system-level trends.

We assessed whether social isolation (SI), social support (SS), and subtypes of SS were associated with self-rated health trajectories and clinical heart failure (HF) outcomes among participants with incident HF hospitalizations. We included 2967 Atherosclerosis Risk in Communities study participants with incident HF hospitalization after Visit 2 (1990–1992). SI, SS, and subtypes of SS were measured at Visit 2. We identified incident HF hospitalization as ICD-9 code 428 and physician adjudicated events; on average HF occurred 17 (SD 8) years after Visit 2. We assessed associations with trajectories of annually measured self-rated health in the 4 years prior to and after incident HF hospitalization (excellent/good self-rated health on a 0–100 scale), using linear mixed effects models. We calculated hazard ratios (HR) and 95% confidence intervals (CIs) for associations with time to first all-cause rehospitalization and all-cause mortality using Cox proportional hazard models. Low overall SS had a 5.8 point (95% CI 7.8, 3.8) lower self-rated health value over time than high SS; associations of subtypes of SS with this outcome were similar. Low belonging SS was associated with greater days to first rehospitalization (HR 0.85; 95% CI 0.79, 0.96) compared to the highest tertile; however, belonging SS was not associated with mortality (HR 1.05; 95% CI 0.95, 1.17). Being socially isolated/high risk for SI was associated with greater hazard of all-cause mortality among females (HR 1.57; 95% CI 1.20, 2.06) but not males (HR 0.95; 95% CI 0.75, 1.19), compared to low SI. SI and SS were not associated with number of hospitalizations in the first year or percent of first year spent at home.by Stefan Saverimuttu, Kate McInnes, Kristin Warren, Lian Yeap, Stuart Hunter, Brett Gartrell, An Pas, James Chatterton, Bethany Jackson
The ability to efficiently derive insights from wildlife necropsy data is essential for advancing conservation and One Health objectives, yet close reading remains the mainstay of knowledge retrieval from ubiquitous free-text clinical data. This time-consuming process poses a barrier to the efficient utilisation of such valuable resources. This study evaluates part of a bespoke text-mining application, DEE (Describe, Explore, Examine), designed for extracting insights from free-text necropsy reports housed in Aotearoa New Zealand’s Wildbase Pathology Register. A pilot test involving nine veterinary professionals assessed DEE’s ability to quantify the occurrence of four clinicopathologic findings (external oiling, trauma, diphtheritic stomatitis, and starvation) across two species datasets by comparison to manual review. Performance metrics—recall, precision, and F1-score—were calculated and analysed alongside tester-driven misclassification patterns. Findings reveal that while DEE (and the principals underlying its function) offers time-efficient data retrieval, its performance is influenced by search term selection and the breadth of vocabulary which may describe a clinicopathologic finding. Those findings characterized by limited terminological variance, such as external oiling, yielded the highest performance scores and the most consistency across application testers. Mean F1-scores across all tested findings and application testers was 0.63–0.93. Results highlight the utility and limitations of term-based text-mining approaches and suggests that enhancements to automatically capture this terminological variance may be necessary for broader implementation. This pilot study highlights the potential of relatively simple, rule-based text-mining approaches to derive insights natural language wildlife data in the support of One Health goals.The UK Health Security Agency and the National Health Service England (NHSE) led a hepatitis C virus (HCV) patient re-engagement exercise beginning in 2018, which entailed sharing public health surveillance data with NHSE Operational Delivery Networks (ODNs) in England. The ODNs used the data to contact and offer testing and treatment to people historically diagnosed with HCV, but who did not have evidence of successfully clearing the virus. A quantitative evaluation found that of 55 329 individuals whose details were shared with ODNs, around 13% had treatment after the exercise commenced. This qualitative evaluation aims to identify the barriers and facilitators to the re-engagement exercise as reported by ODN staff.
Semistructured interviews. The topic guide and analysis were guided by the Theoretical Domains Framework, using a combined deductive framework and inductive thematic analysis approach.
21 staff from 13 ODNs. The sampling frame was designed to capture participants from all regions of England and with varied outcomes from the re-engagement exercise.
Interviewees reported the most barriers in environmental context and resources (including staffing limitations, interruptions during COVID-19, restricted laboratory access), and social influences (with limited responses from general practitioners and patients). Interviewees discussed whether it was appropriate for ODNs and individual staff to be assigned the data validation work and reported some stress and memory/attention barriers due to the volume of the exercise. They had varied beliefs about the consequences of the exercise, with most believing it was worthwhile due to treatment yield, lessons learnt and confirmation that some people had cleared the virus. Further facilitators included the ODN goals fitting with the exercise, and regional resources such as patient databases. Interviewees also reported adaptations to the exercise that facilitated patient contact, and their ongoing work to re-engage patients emphasised outreach partnerships and peer support.
The evaluation revealed insights into methods for re-engaging patients and of sharing and using public health data to support clinical practice. Government support and funding provision for regionally tailored holistic re-engagement approaches, alongside enhancements to health surveillance data, could enable barriers to re-engagement to be overcome.
Low-income adults with disabilities experience disproportionately high rates of food insecurity and preventable healthcare utilisation. The Supplemental Nutrition Assistance Program (SNAP) can reduce food insecurity and improve health, but there are accessibility gaps in the SNAP enrolment process. Existing outreach and enrolment assistance programmes have been shown to boost SNAP enrolment, but their health effects are understudied. This study estimates the effects of a SNAP outreach and enrolment assistance programme on health outcomes among low-income adults with disabilities.
The study pragmatically evaluates a programme that provided outreach and SNAP enrolment assistance for low-income households. The study leverages a random process that selected households for one of two types of outreach, including an information-only arm and an information plus enrolment assistance arm, which formed a control group by default. The study will estimate the effect of this programme among low-income adults with disabilities using Medicaid and SNAP administrative data. Study outcomes include emergency department, hospital and long-term nursing home utilisation. SNAP enrolment and benefit amounts are secondary study outcomes and will be tested as a mediating mechanism of action. The study will test effect heterogeneity based on race, ethnicity, age and chronic conditions.
The study, which relies on deidentified data, was determined to be exempt as human subjects research by the Institutional Review Boards at Johns Hopkins Medicine and the Michigan Department of Health and Human Services. The study is being conducted in ongoing consultation with an Advisory Group of experts in food advocacy and disability advocacy. In addition to disseminating findings in peer-reviewed publications, findings will be disseminated to state decision-makers and the community in partnership with an advisory group.
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.
