To externally validate and subsequently repurpose/recalibrate the easily accessible kidney failure risk equation (KFRE) for a prevalent transplant population with an estimated glomerular filtration rate (eGFR)

Retrospective cohort study using UK Renal Registry data.

68 adult UK kidney centres.

4092 patients with grafts at least 2 years old and eGFR2 from 2009 to 2018.

Death-censored allograft failure at 2 years, defined as dialysis initiation, re-transplantation or, in the absence of the former two, the recorded date of transplant failure.

The KFRE was calculated at baseline using the 2-year, 8-variable non-North American KFRE, and performance was assessed using Harrell’s C-statistic and calibration plots. The model was recalibrated using Cox Regression (2009–2013 cohort) and temporally validated using the 2014–2018 cohort. Clinical utility was assessed using decision-curve analysis, estimating per-100-patient gains in timely planning and reductions in unnecessary interventions compared with eGFR triggers.

The original KFRE had excellent discrimination but was miscalibrated, underpredicting graft failure. Temporal validation demonstrated that the performance of the recalibrated KFRE could be maintained across time periods (Harrell’s C-index of 0.81 (95% CI 0.80 to 0.83); O/E (Observed/Expected events) ratio 1.00 (95% CI 0.93 to 1.07). It identified 9/100 more patients for timely intervention and 13/100 more for whom intervention could be delayed compared with a late clinical trigger of an eGFR2.

While there are other prognostic models, this is the first study to focus on the understudied and clinically important cohort of patients with an eGFR

Glaucoma is a leading cause of irreversible blindness worldwide. Early detection and continuous monitoring are essential to preventing vision loss, yet traditional diagnostic tools remain largely inaccessible in low-resource settings.

This scoping review aimed to map the existing evidence on the use of portable devices for the detection, diagnosis and monitoring of glaucoma.

We conducted a scoping review in accordance with the Joanna Briggs Institute Manual and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A comprehensive search was performed across major databases to identify studies that evaluated handheld tonometers, portable fundus cameras and visual field testing devices. Data were extracted on study design, population characteristics, devices used, comparators and reported outcomes.

A total of 216 studies published between 1975 and 2024 were included. Most studies (90.3%) were method agreement studies, primarily focused on intraocular pressure (IOP) devices. Only two studies evaluated all three glaucoma assessment domains (IOP, visual fields and fundus imaging). Most studies were conducted in high-income countries, with a smaller number from low- and middle-income countries. Despite variability in performance, many devices demonstrated acceptable agreement with gold standard methods and were assessed in a range of clinical and community settings.

This review highlights the range and characteristics of portable glaucoma devices and their potential for enhancing access to diagnosis and monitoring, particularly in underserved settings. However, the predominance of method agreement studies and the limited integration of multimodal assessments point to gaps in the literature. Future research should focus on comprehensive diagnostic pathways using multiple portable tools and on expanding evaluations in low-resource settings to inform policy and service planning.

Eating disorders are complex mental health conditions characterised by pathological behaviours related to food intake, often accompanied by a chronic obsession with weight control. Their prevalence is increasing, with an earlier onset and greater severity among young people. Universal prevention, through multicomponent strategies that tackle modifiable risk factors, has emerged as a promising tool. This paper reports the study protocol designed to assess the effectiveness and cost-effectiveness of the PRETA (Prevención de los Trastornos de la Alimentación) programme in reducing the risk of eating disorders and related modifiable risk factors among preadolescents in the school setting.

The PRETA programme will be assessed by means of an open, community-based, multicentre, controlled trial using 1:1 matched-pairs cluster randomisation at the school level. Schools in Tenerife (Spain) will be assigned to the PRETA programme or a waitlist control group. Participants include 5th- or 6th-grade students (10–13 years old), their parents and teachers. The PRETA programme is a universal, school-based, multicomponent programme designed to reduce eating-disorder risk and modifiable risk factors. Its main component is an interactive online platform called e-PRETA, complemented by training sessions for families and teachers. e-PRETA includes nine 45-minute sessions addressing risk factors, such as dietary habits, beauty standards, media literacy, self-esteem, emotional regulation and social skills. A total of 1068 children from 12 schools will participate. The primary outcome will be the risk of developing eating disorders (Children’s Eating Attitudes Test-26 item version). Secondary outcome measures are body dissatisfaction (Adapted Contour Drawing Rating Scale), eating disorder traits (Eating Disorder Inventory-2), internalisation of appearance ideals (Sociocultural Attitudes Towards Appearance Questionnaire-4) and self-esteem (Rosenberg Self-Esteem Scale). Outcomes will be assessed at baseline and postintervention (3 months). Additional baseline covariates such as electronic device use, parental feeding attitudes, physical activity, sleep duration and screen time will also be collected. Programme effectiveness will be analysed using generalised mixed models. Cost-effectiveness will be assessed by comparing the incremental costs associated with the implementation of the PRETA programme with its estimated effectiveness.

Ethics approval has been obtained from the Ethics Committee for Research with Medicines at the University Hospital of the Canary Islands (CHUC_2021_78). Written informed consent will be obtained from the parents or legal guardians of all participants. Results will be disseminated through scientific publications and conferences.

To estimate the association between municipal multidimensional poverty (MMDP) and the risk of a first hospitalised acute myocardial infarction (AMI) among users of the Chilean public health system, and to examine whether this association differs by sex.

Multilevel analysis of a retrospective cohort study.

Primary level of care across 138 municipalities in Chile.

A total of 137,162 individuals aged ≥45 years were included, comprising 83,598 women and 53,564 men, all enrolled in the cardiovascular health programme of the Chilean public health system due to the presence of cardiovascular risk factors such as hypertension, type 2 diabetes, dyslipidaemia or tobacco use. Individuals with a prior history of AMI were excluded. Participants were clustered by municipality and followed from 1 January 2015 to 30 April 2019. Sociodemographic and clinical data at the individual level were obtained from electronic health records and linked to municipal-level poverty indicators from the National Socioeconomic Characterization Survey.

The primary outcome was the time to first hospitalised AMI . Cox proportional hazard models with a shared frailty term were used to assess the association between MMDP (defined as being in the upper quartile of the index) and AMI incidence. Models were adjusted for individual sociodemographic characteristics, behavioural risk factors (eg, smoking, diet and physical activity), and biological conditions (eg, hypertension, type 2 diabetes and dyslipidaemia). Sex-stratified analyses were conducted to explore potential differences in the association.

MMDP was significantly associated with an increased risk of AMI (HR 1.32, 95% CI 1.06 to 1.64) after adjustment for individual-level risk factors. In stratified models, the association remained significant among women (HR 1.30, 95% CI 1.01 to 1.68), but not among men (HR 1.10, 95% CI 0.93 to 1.31).

Residing in municipalities with high levels of multidimensional poverty is associated with an increased risk of AMI among individuals with cardiovascular risk factors, particularly women. These findings underscore the need for intersectoral policies to address the structural determinants of cardiovascular health.

Sepsis and antibiotic resistance constitute a deadly synergy, causing the loss of millions of lives across the world, with their economic and developmental consequences posing a threat to global prosperity. Their impact is disproportionately felt in resource-limited settings and among vulnerable populations, especially children. A key challenge is prompt diagnosis and timely commencement of appropriate antibiotic therapies. These challenges are compounded in low-income and middle-income countries by a lack of comprehensive epidemiological data, with Nigeria being one such country for which it is lacking. Kaduna is the third largest state in Nigeria, with over 10 million inhabitants, of whom more than half are children under 14 years old. While bacterial sepsis and antimicrobial resistance (AMR) are recognised as a growing problem in the state, there are huge gaps in the current understanding of their aetiology. This project employs a cross-sectional design to investigate the clinical and haematological markers of paediatric sepsis, alongside determining the bacterial cause and prevalence of AMR at four high-turnover hospitals in Kaduna State, Nigeria. Further, whole-genome sequencing of isolated bacterial pathogens will be performed to determine the genetic features of resistance. This project represents the largest surveillance study of paediatric sepsis in Kaduna to date. Additionally, we aim to use the clinical, haematological, microbiological and genomic data to derive predictive models for sepsis causes, treatment strategies and patient outcomes.

This is a hospital-based, cross-sectional study that will recruit up to 461 children with bacterial sepsis who were admitted at the two teaching and two general hospitals in Kaduna State, Nigeria. Children presenting with features of fever, subnormal temperature and body weakness would be recruited into the study and have their blood samples collected. The blood samples will be used for culture, complete blood count, HIV and malaria testing. Accordingly, we will capture clinical presentation, haematological characteristics, causative pathogen from blood culture and patient outcomes. Nutritional status, known congenital immunosuppressive diseases, HIV infection and malaria infection will also be determined and documented. The bacterial isolates will be phenotypically characterised for AMR and genotypically following whole genome sequencing. Known and potential confounders to the outcomes of bacterial sepsis would be assessed in all participants, and adjustment for confounding would be performed using logistic regression and/or stratification±Mantel-Haenszel estimator where applicable.

Ethical approvals were granted by the University of Birmingham (ERN_2115-Jun2024), the Ahmadu Bello University Teaching Hospital (ABUTHZ/HREC/H45/2023), Barau Dikko Teaching Hospital, Kaduna (NHREC/30/11/21A) and the Kaduna State Ministry of Health (MOH/AD M/744/VOL.1/1110018). The study will be conducted using the international guidelines for good clinical practice and based on the principles of the Declaration of Helsinki. The results will be disseminated via oral and poster presentations in scientific conferences and published in peer-reviewed journal articles.

There are currently no validated screeners that evaluate diet and lifestyle of people living with and beyond cancer (PLWBC). The purpose of this study was to reach a consensus among an international expert panel on the essential items to include in this type of instrument.

A scientific committee developed the initial list of items, which were presented to an expert panel in a two-round-modified electronic Delphi. Panellists were asked to rate the adequacy, relevance and feasibility of self-reporting each item. Qualitative assessments were encouraged.

Four countries (Spain, UK, USA and Portugal).

Experts working in a cancer-related health profession or cancer-related research were recruited.

Items were initially categorised into seven domains (body composition, physical activity, diet, alcohol, smoking, sleep and psychosocial distress). A content validity index per item (CVI-i) and a scale-level CVI (S-CVI) were calculated (acceptable≥0.78). All items with a CVI-i≥0.78 were submitted to a final consensus meeting.

A total of 108 items were proposed to the panel. In Round 1, 77 items were accepted, 10 items were excluded and 6 new items were proposed. During Round 2, 4 items were accepted and 19 were excluded. Diet and alcohol were merged into one domain. The final consensus meeting decided on 61 items categorised into six domains (S-CVI:0.94): body composition, physical activity, diet and alcohol, smoking, sleep and psychosocial distress.

We identified the main items to be considered when developing a screener to evaluate diet and lifestyle in PLWBC in a clinical setting, and the results obtained will guide the content of the screener in the following validation study.

Prescribing antibiotics may reinforce patients’ beliefs that antibiotics are needed and increase future consultations for similar symptoms. This review determines the effect of antibiotic prescribing for respiratory infections in primary care on future reattendance.

A systematic review and meta-analysis of randomised controlled trials (RCTs) and cohort studies and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Participants were adults or children presenting with respiratory infection in primary care.

MEDLINE (Ovid), PubMed, Embase, the Cochrane Central Register of Controlled Trials, clinical trial registries and grey literature sources were searched from inception until 6 February 2024.

Eligible studies included open-label RCTs or cohort studies of antibiotics compared with no antibiotics in adults or children with respiratory infections. The outcome of interest was reattendance at least 28 days after the initial consultation.

Two reviewers independently screened, selected, assessed the quality and extracted data. Separate meta-analyses were presented for RCT and cohort studies and a combined meta-analysis of all studies.

We identified 2128 records and reviewed 48 full texts, of which five met the inclusion criteria. These reported three RCTs (1207 randomised to antibiotics, 672 controls) and three cohort studies (209 138 exposed to antibiotics, 46 469 controls). In the meta-analysis of RCTs, relative risk (RR) of reattendance with antibiotics was 1.10 (95% CI: 0.99 to 1.23), and in cohort studies, RR was 1.21 (95% CI: 0.94 to 1.49). An important limitation is that most studies were in UK primary care.

Evidence suggests prescribing antibiotics for acute respiratory tract infections in primary care probably modestly increases future reattendance for similar conditions. Reducing antibiotic prescribing may help decrease demand for primary care.

International consensus guidelines support the initial administration of 30 mL/kg of intravenous fluids for haemodynamic resuscitation of newly diagnosed septic shock. Practice variation exists between the volume of fluids administered and timing of vasopressor commencement. The optimal approach in patients with septic shock is uncertain.

Australasian Resuscitation In Sepsis Evaluation: FLUid or vasopressors In emergency Department Sepsis is a 1000-participant multicentre, randomised, open-label, parallel group clinical trial conducted in patients with septic shock presenting to the emergency department in participating sites in Australia, New Zealand and Ireland. Participants are randomised (1:1) to either restricted fluids and early vasopressors or a larger initial intravenous fluid volume and later vasopressors. The primary outcome is days alive and out of hospital at day 90 postrandomisation. Secondary outcomes are all-cause mortality at day 90, time from randomisation until death (to day 90), days alive and at home at day 90 and ventilator-free, vasopressor-free and renal replacement-free days to day 28 postrandomisation and death or disability at 6-month and 12-month postrandomisation. Health-related quality of life will be assessed at day 180 and 12 months following randomisation.

The study was approved by Northern Sydney Local Health District Human Research Ethics Committee (HREC2020/ETH02874) on 21 January 2021. Patients will be enrolled under a waiver of prior consent. The patient or next-of-kin (or equivalent according to local jurisdiction) is approached at the first available opportunity and given a trial information sheet. According to local approvals, the patient or next-of-kin chooses to either continue in the trial or opt-out/decline continued participation. Results will be disseminated in peer-reviewed journals and presented at academic conferences.
