While almost half of older adults admitted to hospital are prescribed potentially inappropriate medicines, less than 1% have a medicine proactively deprescribed during admission in the UK. The CompreHensive geriAtRician-led MEdication Review (CHARMER) intervention is designed to address geriatricians’ and pharmacists’ barriers and enablers to deprescribing. The CHARMER definitive trial will evaluate effectiveness, cost-effectiveness and safety.
A stepped-wedge cluster randomised controlled trial will be conducted in 20 hospitals in England, with four hospitals in reserve. All hospitals will collect baseline data. Every 3 months, five hospitals will be randomised to receive the intervention. The intervention, implemented by a local project manager, comprises a hospital action plan to set deprescribing as an organisational goal; workshops for pharmacists and geriatricians to change beliefs about deprescribing; weekly briefings between geriatricians and pharmacists to discuss opportunities for deprescribing; benchmarking reports to compare deprescribing performance across participating hospitals. With an average of 200 patients admitted and discharged during each step, the study will have 89.5% power at 5% significance level and intra-class correlation coefficient of 0.05 to detect a 3% difference in 90-day re-admission rate from 16.7% versus 13.7%. Anonymised routinely collected data, including readmissions, will be obtained for all patients admitted during the study period. Enhanced data collection periods of 1 month during control and intervention periods will be used to recruit patients and data for secondary outcomes and process evaluation.
A stepped-wedge design enabled a smaller number of hospitals and patients to be included than a traditional cluster-randomised design. The complexity of intervention implementation necessitated a project manager in addition to the principal investigator responsible for trial conduct. Using routinely collected data for the primary outcome measure should ensure that the trial has sufficient power on completion. Planned enhanced data collection for short periods of time improves trial efficiency.
To describe prescription patterns, dosing and persistence of guideline-directed medical therapy (GDMT) among patients with heart failure with reduced ejection fraction in Singapore, and to identify factors associated with the use of quadruple therapy (ACE inhibitor (ACEi)/angiotensin II receptor blocker (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), β-blocker, mineralocorticoid receptor antagonist (MRA) and sodium-glucose cotransporter-2 (SGLT2) inhibitor).
Retrospective, observational cohort study.
Secondary and tertiary care settings across seven public hospitals in Singapore.
3999 adults hospitalised from 2020 to 2022 with a first heart failure-related admission and left ventricular ejection fraction ≤40%. Patients with absolute contraindications to specific GDMT classes were excluded from eligibility calculations.
Primary outcomes were the proportions of eligible patients prescribed each GDMT class and quadruple therapy at discharge. Secondary outcomes were 6-month prescription patterns, dose attainment and predictors of quadruple therapy use.
Among eligible patients, 80%–99% met criteria for each GDMT drug class, yet only 29% received quadruple therapy at discharge in 2022. Prescription rates for ACEi/ARB/ARNI (67%), beta-blockers (89%), MRAs (40%), and SGLT2 inhibitors (46%) remained suboptimal despite high eligibility. At discharge, over 90% of patients on ACEi/ARB/ARNI and beta-blockers received ≤50% of target doses. By 6 months, prescription rates declined by 16% for ACEi/ARB/ARNI, 26% for beta-blockers and 7% for MRAs, while SGLT2 inhibitor use increased. Older age (OR 0.97, 95% CI 0.96 to 0.98) and chronic kidney disease stage 3a–4 (OR 0.65 to 0.04) were associated with lower odds of receiving quadruple therapy, while significant institutional variation was observed.
Despite high eligibility, uptake and optimisation of GDMT remain poor in Singapore, with substantial treatment gaps driven by underprescription, inadequate dosing and discontinuation. Interventions targeting clinician awareness, postdischarge support and institutional practice variation may improve adherence to guideline-recommended therapy.
Hand osteoarthritis (OA) is a prevalent and debilitating joint disorder that impairs daily functioning and quality of life. Current treatments are often inadequate in managing the symptoms and progression of the disease. The cytokine interleukin (IL)-17 has been implicated in the inflammatory processes associated with OA, making it a potential target for therapeutic intervention. This trial aims to evaluate the efficacy of vunakizumab, an IL-17A inhibitor, in reducing pain and improving functional outcomes in patients with erosive hand OA.
This multicentre, randomised, placebo-controlled, double-blind trial will enrol 150 participants aged 30–80 years with symptomatic erosive hand OA. Participants will be randomised in a 1:1 ratio to receive either vunakizumab 120 mg or placebo subcutaneously every 4 weeks for 24 weeks, with a loading dose injection period during the first 4 weeks. The primary outcome is the change in hand pain assessed by the Visual Analogue Scale at 28 weeks. Secondary outcomes include changes in physical function measured by the Functional Index for Hand Osteoarthritis, the Quick Disabilities of the Arm, Shoulder and Hand questionnaire and the Health Assessment Questionnaire, as well as changes in grip strength and radiographic and MRI evaluations of the hands.
Written informed consent will be obtained from all participants. The study was approved by the Ethics Committee of Shanghai Sixth People’s Hospital (2024–217) and will adhere to the Declaration of Helsinki. Research results will be published in peer-reviewed journals.

To examine inpatient benzodiazepine receptor agonists prescribing patterns and assess how hospitalisation affects use at discharge.
Subanalysis of the WEsleep trial, a cluster-randomised controlled single-centre study conducted at Amsterdam University Medical Center (Amsterdam UMC) (two locations) between July 2023 and March 2024. Twelve departments (six medical, six surgical) were matched and randomised to intervention or standard care. On intervention wards, multiple measures to improve sleep were implemented, including minimising nighttime disruptions.
Amsterdam UMC, across medical and surgical hospital departments.
Adult patients admitted for ≥2 nights (medical) or undergoing elective non-cardiac surgery in a surgical department.
Benzodiazepine use was classified as no use, pre-admission use or new in-hospital initiation. Prescribing patterns were summarised descriptively according to type, timing, indication and discharge status.
Of 746 patients, 187 (25%) used benzodiazepines: 80 (43%) had pre-admission use, and 107 (57%) were newly initiated during their hospital stay. Among pre-admission users, two discontinued and five had adjustments at discharge. Among newly initiated users, 94 (88%) had their benzodiazepine discontinued at discharge. Approximately half of pre-admission prescriptions and one-third of in-hospital prescriptions lacked a documented indication.
Although most newly initiated benzodiazepine treatments were discontinued during hospitalisation, pre-existing use was rarely reassessed and nearly 10% of new users were discharged with a prescription. Structured deprescribing protocols, better documentation of indications and improved discharge planning are needed to promote safer and more rational benzodiazepine use.
Within the UK there are 33 deaths every day from prostate cancer, second only to lung cancer as the most common cause of cancer death in males in the UK. Of the 55 000 new cases each year, up to 50% of these patients will receive radiotherapy either alone or after prostatectomy. Although there have been significant improvements in the accuracy of radiotherapy delivery leading to better tumour targeting and a reduction in dose to normal tissues, significant permanent genito-urinary or gastrointestinal-related side effects are all too common. With nearly 80% of patients with prostate cancer surviving for 10 years or more, minimising life-limiting radiation damage to normal tissues is vitally important. However, at present, it is not possible to identify which patients will suffer a poorer outcome after radiotherapy. The aim of this study, improving radiotherapy in PROState cancer using EleCtronic population-based healthCAre data (PROSECCA), is to do this by using the existing information in a patient’s digital healthcare record. By linking primary, secondary and tertiary clinical data, including digital image information, with radiotherapy treatment plans and outcome data, the PROSECCA study will identify de novo predictive biomarkers of radiation response and provide clinicians with a tool to individualise a radiotherapy dose and plan to maximise cure and minimise toxicity.
The PROSECCA study is a large multidisciplinary project, the purpose of which is to analyse healthcare records from up to 15 000 patients with prostate cancer who underwent radiotherapy in the treatment of their cancer in Scotland between 2010 and 2022. Through the linkage of data obtained specifically for radiotherapy and data held within each patient’s unique electronic health record (EHR), the factors that indicate why some patients have a poor response to treatment, or an increased risk of side effects from radiation, will be identified. This will be made possible by the use of artificial intelligence and machine learning (AL/ML), which will help to identify at-risk patients earlier and allow adaptation of their treatment accordingly.
The study is being conducted in accordance with the ethical principles set out in the Declaration of Helsinki and Good Clinical Practice that respects and protects the rights, and maintains confidentiality, of all trial participants. The study protocol (V.1.0) was reviewed by the South Central Oxford A Research Ethics Committee (REC) on 13 December 2021 and received a favourable opinion subject to each National Health Service (NHS) organisation confirming permission for patients treated within their area. Approval for the use of unconsented healthcare record data for patients included in the study and treated at one of the five Scottish Cancer Centres required an application to the NHS Scotland Public Benefit and Privacy Panel for Health and Social Care (HSC-PBPP). Full approval from the HSC-PBPP panel was received on 1 July 2024, which covered the use of pseudoanonymised EHR data for all patients participating in the study. The study is publicly listed on the NHS Health Research Authority site, with IRAS ID 306245 and REC reference 21/SC/0402. Dissemination of the study findings will take place through field-leading cancer, radiation oncology and medical physics journals. All manuscripts will be approved by the main study team and authorship determined by mutual agreement.
Large-scale stroke registries can provide critical insights into disease mechanisms, progression and healthcare needs, informing prevention and care. However, few collect detailed demographic, brain imaging, and comprehensive long-term follow-up data. To address this, we established the prospective Stroke Investigation Group in North And central London (SIGNAL) registry in 2017.
The SIGNAL registry included 3931 adults aged ≥18 years with confirmed acute stroke (cerebral ischaemia or intracerebral haemorrhage (ICH)) admitted to the University College London Hospital hyperacute stroke unit between January 2017 and 2020, drawn from an ethnically diverse North and Central London population (~1.6 million). Baseline data included demographic, clinical, brain imaging and next-of-kin information. Six month follow-up included measures of functional status and non-motor outcomes (anxiety, depression, fatigue, sleep, pain, language, continence, social participation, cognition) via face-to-face, telephone or postal follow-up methods.
The mean age of individuals included in the SIGNAL registry was 72.1 years, and 1806 (45.9%) were female. The ethnic distribution comprised 2365 (60%) white, 649 (16.5%) black and 511 (13%) Asian. Stroke diagnoses included 3371 (85.8%) with cerebral ischaemia and 560 (14.2%) with ICH. On admission, 2240 individuals (57.0%) had a National Institutes of Health Stroke Scale score >4, indicating moderate stroke severity. At hospital discharge, the median functional outcome, measured by the modified Rankin Scale, was 3 (IQR 1–4), indicating moderate disability. At 6 months, functional outcomes measured with mRS were available for 3755 individuals (95.6%) with a median score of 1 (IQR=0–3) and non-motor outcomes were available for 3080 individuals (92.3%). The most prevalent adverse non-motor outcomes were fatigue 1756 (57%), reduced social participation 1694 (55%) and sleep disturbance 1663 (54%).
Further analyses of SIGNAL registry data will investigating associations between stroke mechanisms, subtypes and neuroimaging features and 6-month functional status, non-motor outcomes and cognitive impairment. Longer term follow-up of survivors for ~10 years is also planned.
Administering supplemental oxygen to prevent hypoxaemia is a fundamental treatment for patients hospitalised with acute injury or illness. However, the amount of oxygen administered frequently exceeds that needed to maintain normoxaemia, causing patients to experience hyperoxaemia and wasting supplemental oxygen. Closed-loop, autonomous oxygen titration systems are designed to optimise oxygen delivery by administering the lowest possible oxygen flow that maintains peripheral oxygen saturation (SpO2) within a predefined range. For adults hospitalised with an acute injury or illness, it remains uncertain whether the use of a closed-loop, autonomous oxygen titration system safely increases the proportion of time spent in normoxaemia (SpO2 90%–96%) compared with usual care.
The Strategy to Avoid Excessive Oxygen using Autonomous Oxygen Titration Intervention trial is a multicentre, unblinded, parallel-group, randomised trial being conducted at four level 1 trauma centres in the USA. The trial compares an autonomous oxygen titration system versus usual care among 300 adults hospitalised for major trauma, burn, acute care surgery or acute respiratory illness. The primary outcome is the proportion of patient-time spent within the targeted normoxaemia range (SpO2 90%–96%) as measured by continuous non-invasive pulse oximetry, during the first 72 hours after randomisation. Secondary outcomes include the amount of supplemental oxygen administered and the proportion of time spent in hypoxaemia (SpO22 >96%). Specifying the protocol and statistical analysis plan before the conclusion of enrolment increases the rigour, reproducibility and interpretability of the trial. Enrolment began on 6 May 2024.
The trial protocol was approved by the single institutional review board at the University of Colorado School of Medicine and the Office of Human Research Oversight at the Department of Defense. We will present the results at scientific conferences and submit them for publication in a peer-reviewed journal.
Effect size and event rate estimation is necessary for sample size calculation in randomised clinical trials. Overestimation of the effect size and event rate can lead to inadequately powered studies and increased probability of false negative results. This is common in trials involving critically ill patients. However, such overestimation has not been systematically evaluated in trials involving neurocritical care. We aimed to conduct a systematic review of published randomised clinical trials involving critically ill neurological patients, to determine the accuracy of effect size and event rate estimation.
We will review randomised clinical trials involving adult critically ill neurological patients that were published from 2015 onwards in selected clinically useful and high-impact journals. We will include randomised clinical trials reporting a binary or time to event outcome, using two study groups, and a superiority design testing the efficacy of diagnostic, monitoring, therapeutic or process interventions. All eligible studies must report an estimated event rate in the control group and estimated effect size. All relevant studies will be identified through database searches. All study selection and data extraction will be conducted by two independent reviewers. We will use a random-effects model for pooling data. This review will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines. Accuracy of effect size and event rate estimation will be evaluated by comparing the estimated and observed values. The association between the accuracy of the individual randomised clinical trial effect size and event rate estimation and rejection of the null hypothesis will be evaluated using logistic regression analysis. Multivariable linear regression analysis will be used to explore the factors associated with accuracy of effect size and event rate estimation. In addition, we will perform subgroup analysis by impact factor of the published journals, sample size of the studies and risk of bias.
As this systematic review will use data from previously published studies, it does not require ethics approval. Findings of this systematic review will be published in a peer-reviewed journal and will be presented at specialty-based conferences. The study will be included in the higher degree research thesis of the primary author.

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.
Commentary on: Danne et al. Association Between Treatment Adherence and Continuous Glucose Monitoring Outcomes in People With Diabetes Using Smart Insulin Pens in a Real-World Setting. Diabetes Care. 2024.47 (6),:995-1003
Implications for practice and research Healthcare providers should emphasise consistent insulin adherence for people with diabetes, as even a few missed doses can worsen overall glycaemia. Future research should identify barriers to consistent usage of insulin and develop strategies to enable patients’ adherence, such as increasing patient engagement with smart insulin pens and continuous glucose monitoring systems.
Diabetes is a widespread chronic disease, with steadily rising prevalence in most countries. In 2019, the global prevalence of diabetes was estimated at 9.3%, affecting 463 million people. This figure is projected to rise to 10.2% by 2030 and 10.9% by 2045.
Persistent somatic symptoms and functional disorders are conditions requiring a biopsychosocial approach to care, often from multiple professionals. The fragmentation of care common in most health systems results in unsatisfactory and challenging care experiences. Collaborative care networks form an important route towards improving outcomes and the overall experience of care for patients and professionals. While we have a good idea of what such collaborative care networks can look like, we lack knowledge on the practicalities of implementing change in such networks.
The core objective of this study is to implement change in a collaborative care network for persistent somatic symptoms and functional disorders care. Our questions were twofold: first, what are examples of realistic action processes to improve such collaborative care networks? Second, what are, in our experience, conditions for an effective change process in such a collaborative care network?
Participatory action research approach embedded within an active regional network between May 2023 and May 2024. The process was led by an action group who selected objectives and related actions with the aim of improving the network, leading to better care for people with persistent somatic symptoms and functional disorders as well as improving satisfaction among professionals.
ALK Netwerk Salland, a regional network of professionals and experts-by-experience, focused on care of persistent somatic symptoms. This network is based in the Salland region in the east of the Netherlands, centred around the city of Deventer.
The action group was made up of local stakeholders including experts-by-experience and health and social care professionals, facilitated by a researcher-in-residence. Other participants included members of the regional network who provided input towards the different objectives.
Over the course of a year, three objectives were selected and enacted, including assessing the resources of the network, improving knowledge of treatment options and improving the shared vision of care. The process faced some challenges, such as changes in action group members and a lack of resources and time to enact changes. However, by having a trusted and engaged team, working with an active network, we were able to enact significant changes to the network, which may be sustained and built on through the ongoing action group.
Future participatory action research studies would benefit from a trusted and embedded researcher-in-residence, meaningful involvement early in the process of experts-by-experience, and serious consideration of realistic outcome measures to monitor for evaluation of changes made.
Post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) is associated with future major adverse cardiac events and may reflect residual ischaemia and suboptimal stent result (SSR). Post-PCI FFR should therefore be considered to identify patients at high risk. Whether abnormal post-PCI FFR and non-hyperaemic pressure ratios, including resting full-cycle ratio (RFR), represent SSR after PCI remains to be determined, especially after chronic total occlusion (CTO) PCI. In addition, little is known about the association between post-PCI intracoronary physiology and SSR with residual anginal complaints.
The physioLogy to evaluaTe procedural Result After percutaneous coronary intervention of Chronic Total Occlusion study is a prospective, multicentre, exploratory, mechanistic, investigator-initiated, single-arm study with a non-inferiority design. A total of 200 patients, undergoing CTO PCI, with FFR and RFR measured in all patients, will be included at two study sites in the Netherlands. The primary endpoint is the area under the curve (AUC) of post-PCI RFR, in comparison to the AUC of post-PCI FFR, for prediction of optical coherence tomography-detected SSR and its individual components.
The study is approved by the local ethical review board (‘Medisch Ethische Toetsing Commissie Isala Zwolle’). Written informed consent will be obtained from all patients before enrolment. The outcomes of this study are intended to be disseminated in a peer-reviewed journal.
Crohn’s disease (CD) and ulcerative colitis (UC) are chronic, inflammatory bowel diseases (IBDs) of unknown origin, affecting the gastrointestinal tract and often causing extraintestinal symptoms. Conventional treatments (eg, glucocorticosteroids, immunomodulators) and targeted advanced treatments, including anti-TNFα, antibodies to p40 subunit of IL-12/23, antibodies to p19 subunit of IL-23, anti-α4β7 integrin, Janus kinase inhibitors (JAKis) and sphingosine-1-phosphate receptor (S1PR) modulators, do not achieve sustained responses for all patients, leaving significant unmet therapeutic needs.
This prospective, multi-centre observational study will follow a cohort of 240 patients across multiple study centres within NHS trusts in the UK who are initiating or switching biologics, specifically anti-TNFα and anti-α4β7 integrin for UC, and anti-TNFα, antibodies to p40 subunit of IL-12/2 and JAKi for CD. Through comprehensive profiling of immunological, transcriptional, microbiome, genetic and proteomic markers at baseline, week 12, and week 52, this study aims to uncover non-invasive biomarkers that predict response to these drug classes, ultimately advancing personalised medicine in IBD.
Ethical approval for the Nottingham/AstraZeneca study was granted by the West of Scotland Research Ethics Committee. Recruitment began in December 2022 and is currently ongoing at 10 NHS Trust sites across the UK. Study findings will be disseminated by publication in peer-reviewed journals and presentations at relevant national and international conferences.
Economic evaluations in healthcare can guide practice and inform policy. The objective of this paper is to present the protocol for a health economic evaluation comparing the cost-effectiveness of prophylactic treatment using pantoprazole 40 mg daily compared with no pantoprazole to prevent upper gastrointestinal (GI) bleed among invasively ventilated patients.
This is an economic evaluation conducted alongside the
The trial was approved by each participating institution; this economic evaluation was approved by the Hamilton Integrated Research Ethics Board. Given widespread daily use of proton pump inhibitors for critically ill patients, the results of this economic evaluation will be of high relevance to patients, family members, physicians, pharmacists, policymakers and guideline developers. Integrated knowledge translation will involve periodic progress reports to collaborators. End-of-study knowledge translation will include rounds, videoconferences, abstracts and slide-decks for intensive care unit quality councils and healthcare organisations, and open-access publications. Patient and family partners will co-create lay language summaries for traditional and social media to help inform all interest groups.
To determine the prevalence and factors associated with the uptake of HIV self-testing (HIVST) among adolescent girls and young women (AGYW) attending middle learning institutions in Dodoma City, Tanzania, in 2024.
Design: A cross-sectional study design was employed.
The study was conducted in five randomly selected colleges in Dodoma City, Tanzania.
A total of 771 female students aged 15–24 years who provided informed consent were enrolled. Students who declined participation or were reported by the college matron as medically unfit were excluded. In this study, ‘sick’ referred to participants with a clinically diagnosed illness rendering them unable to participate.
The primary outcome was the uptake of HIVST among participants.
The mean age of participants was 20.78 years (SD=1.85). Overall, 360 participants (46.7% (95% CI 43.2% to 50.2%) reported having used HIVST. Among those who had not tested, the most commonly reported barriers included cultural resistance 392 (95.4%), fear of judgement from healthcare providers, 372 (90.5%); legal restrictions on kit provision, 360 (87.6%); fear of testing procedures, 291 (70.8%); concerns about test reliability, 286 (69.6%); fear of test results, 283 (68.9%); limited accessibility to HIVST kits, 280 (68.1%); fear of others discovering they had tested, 273 (66.4%); low awareness of HIVST, 193 (47.0%); and a perceived low risk of HIV infection, 73 (17.8%).
Factors significantly associated with HIVST uptake included having multiple sexual partners adjusted prevalence ratio (aPR 1.23, 95% CI 1.05 to 1.45), studying health-related courses (aPR 1.14, 95% CI 1.04 to 1.27), availability of kits (aPR 2.83, 95% CI 2.21 to 3.62), previous HIV testing experience (aPR 2.65, 95% CI 2.05 to 3.43) and perceiving oneself at risk of HIV infection (aPR 1.29, 95% CI 1.11 to 1.50).
The uptake of HIVST among AGYW in Dodoma City remains below the national target of 95% HIV awareness among people living with HIV. Uptake was influenced by factors such as multiple sexual partnerships, study discipline, kit availability, prior testing experience and perceived risk of infection. Addressing the identified barriers and improving awareness and accessibility of HIVST could enhance testing rates among AGYW.
Saskatchewan is facing a public health crisis driven by high rates of HIV, syphilis and hepatitis C virus (HCV) infections, particularly among people who use drugs. Injection drug use is a major contributor to these syndemic infections, exacerbated by structural barriers such as stigma, poverty and limited culturally safe healthcare. Innovative, community-informed approaches are urgently needed to improve prevention, testing and linkage to care.
This study will implement a rapid assessment and response system in Regina, Saskatchewan, Canada, integrating geospatial mapping of community needle prevalence with pop-up interventions. Needle hotspot maps will be used to guide the deployment of community-based pop-up events offering point-of-care testing for HIV, syphilis and HCV, alongside education on pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP). A convergent participatory mixed-methods design will be used to evaluate feasibility, acceptability and effectiveness, guided by the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. Quantitative data will assess changes in knowledge of PrEP and PEP, satisfaction with the intervention and report new diagnoses and participant demographics descriptively. A qualitative substudy will include 30 participants and will explore experiences with the intervention, barriers to care and perceptions of service delivery.
Ethical approval has been obtained from the research ethics board of the Saskatchewan Health Authority (#24–91). Findings will be disseminated through peer-reviewed publications, conference presentations and community reporting. This study may provide a model of community-based geospatial testing and education that could be scaled up and adapted elsewhere.

The predisposition to food allergy development and the induction of allergen-specific immune responses appears to be initiated early in infancy. Early exposure to food allergens, such as peanut and cashew nut, via human milk is likely important in initiating oral tolerance and reducing risk of food allergy development. This trial aims to determine if the risk of developing peanut and cashew nut allergy during infancy can be reduced by a high peanut and cashew nut maternal diet during lactation.
This is a multisite, parallel, two-arm (1:1 allocation), single-blinded (outcome assessors, statistical analyst and investigators), randomised controlled trial. Target sample size is 4412 participants (2206 per group). Women (aged 18–50 years) with a singleton pregnancy, who are planning to breastfeed and do not have peanut and/or cashew nut allergies are eligible to participate. After obtaining written informed consent, participants are randomised to either a high peanut and cashew nut diet (at least 60 peanuts and 40 cashew nuts per week) or a low peanut and cashew nut diet (no more than 20 peanuts and 12 cashew nuts per week). Participants are asked to follow their allocated diet from birth to 6 months postnatal. Individual lactation consultant advice and support is provided as required. The study’s primary outcome is food challenge proven IgE-mediated peanut and/or cashew nut allergy during infancy (0–18 months). Key secondary outcomes include infant sensitisation to peanut and/or cashew nut. Analyses will be performed on an intention-to-treat basis according to a prespecified statistical analysis plan.

Diabetes affects ~10% of the world’s population and is rising. Treatment costs in the UK are ~15% of the NHS budget. Diabetes-related complications can be lowered through better evidence-based clinician management and patient self-management. MyWay intelligence quotient (MWIQ) is an electronic platform that will provide clinical decision support around the diagnosis and treatment of patients with diabetes. This study evaluates the safety and clinical performance (clinical appropriateness/applicability, clinical impact and clinical usability) of MWIQ.
The system will be implemented in real time in four to seven general practitioner (GP) practices. Clinicians with diabetes expertise will be recruited as validators, who will inspect records to ensure system robustness before use, and up to 14 healthcare professionals will use and evaluate the system.
Quantitative and qualitative analyses will be triangulated to assess the MWIQ system. Assessment of clinical outcomes will be made using pseudonymised routinely collected clinical data, including adherence to quality performance indicators, diabetes diagnosis, diabetes investigations (eg, genetic testing), HbA1c, blood pressure, body mass index, cholesterol and foot risk score for the diabetes population concerned. Clinical and validator participants will also submit a weekly questionnaire, and these, along with interviews, which are scheduled during the testing process, will be analysed to provide data on the utility, safety and usability of the system.
This study was approved, 08/01/2024, by the North of Scotland Research Ethics Committee (REC), IRAS project ID: 305267, REC, reference 23/NS/0134. The study has gained confidentiality advisory group (CAG) support (reference: 24/CAG/0002), medicines and healthcare products regulatory agency (MHRA) and health research authority (27/08/2024) approvals.
Findings will be reported to (1) The funding body, (2) The participating GP practices, (3) The study PPIE group, (4) The MHRA to support a submission for recognition as a class 2 CE/UKCA marked device, (5) Presented at local, national and international conferences and (6) Disseminated by peer-reviewed publications.
There are substantial barriers to initiate advance care planning (ACP) for persons with chronic-progressive disease in primary care settings. Some challenges may be disease-specific, such as communicating in case of cognitive impairment. This study assessed and compared the initiation of ACP in primary care with persons with dementia, Parkinson’s disease, cancer, organ failure and stroke.
Longitudinal study linking data from a database of Dutch general practices’ electronic health records with national administrative databases managed by Statistics Netherlands.
Data from general practice records of 199 034 community-dwelling persons with chronic-progressive disease diagnosed between 2008 and 2016.
Incidence rate ratio (IRR) of recorded ACP planning conversations per 1000 person-years in persons with a diagnosis of dementia, Parkinson’s disease, organ failure, cancer or stroke, compared with persons without the particular diagnosis. Poisson regression and competing risk analysis were performed, adjusted for age, gender, migration background, living situation, frailty index and income, also for disease subsamples.
In adjusted analyses, the rate of first ACP conversation for persons with organ failure was the lowest (IRR 0.70 (95% CI 0.68 to 0.73)). Persons with cancer had the highest rate (IRR 1.75 (95% CI 1.68 to 1.83)). Within the subsample of persons with organ failure, the subsample of persons with dementia and the subsample of stroke, a comorbid diagnosis of cancer increased the probability of ACP. Further, for those with organ failure or cancer, comorbid dementia decreased the probability of ACP.
Considering the complexity of initiating ACP for persons with organ failure or dementia, general practitioners should prioritise offering it to them and their family caregivers. Policy initiatives should stimulate the implementation of ACP for people with chronic-progressive disease.

This study was nested within the AlzEye cohort, which links longitudinal multimodal retinal imaging data routinely collected from a large tertiary ophthalmic institution in London, UK, with nationally held hospital admissions data across England.
A total of 675 individuals (1129 eyes) with PDR were included from the AlzEye cohort. Participants were aged ≥40 years (mean age 57.3 years, SD 10.3), and 410 (60.7%) were male.
The primary outcome was all-cause mortality. Quantitative retinal markers were derived from fundus photographs and optical coherence tomography using AutoMorph and Topcon Advanced Boundary Segmentation, respectively. We used unadjusted and adjusted Cox-proportional hazards models to estimate hazard ratios (HR) for the association between retinal features and time to death.
After adjusting for sociodemographic factors, each 1-SD decrease in arterial fractal dimension (HR: 1.54, 95% CI: 1.18 to 2.04), arterial vessel density (HR: 1.59, 95% CI: 1.15 to 2.17), arterial average width (HR: 1.35, 95% CI: 1.02 to 1.79), central retinal arteriolar equivalent (HR: 1.39, 95% CI: 1.05 to 1.82) and ganglion cell-inner plexiform layer (GC-IPL) thickness (HR: 1.61, 95% CI: 1.03 to 2.50) was associated with increased mortality risk. When also adjusting for hypertension, arterial fractal dimension (HR: 1.45, 95% CI: 1.08 to 1.92), arterial vessel density (HR: 1.47, 95% CI: 1.05 to 2.08) and GC-IPL thickness (HR: 1.56, 95% CI: 1.03 to 2.38) remained significantly associated with mortality.
Several quantitative retinal markers, relating to both microvascular morphology and retinal neural thickness, are associated with increased mortality among individuals with PDR. The role of retinal imaging in identifying those individuals with PDR most at risk of imminent life-threatening sequelae warrants further investigation.
