To examine how socioeconomic deprivation influences referral pathways to emergency departments (EDs) and to assess how these pathways affect subsequent hospital outcomes.

Retrospective observational study.

Emergency department of a large teaching hospital in the East of England, providing secondary and tertiary care.

482 787 ED attendances by patients aged 16 years and over, recorded between January 2019 and December 2023. Patients were assigned Index of Multiple Deprivation (IMD) deciles based on residential postcode.

Referral source (general practitioner (GP), National Health Service (NHS) 111, ambulance, self-referral, other), total ED time, 4-hour breach, hospital admission and unplanned return within 72 hours.

Substantial socioeconomic inequalities were observed in referral pathways. Patients from the most deprived areas were significantly less likely to be referred by a GP (4.7%) than those from the least deprived areas (14.7%) and more likely to arrive via ambulance (32% vs 24%). These differences persisted after adjusting for demographic, clinical and contextual variables. Ambulance referrals showed the longest ED stays, ranging from 347 to 351 min across IMD deciles (overall 95% CI 343 to 363) and the highest probability of 4-hour breaches (51%; 95% CI 50% to 53%). Self-referrals had the greatest rates of unplanned returns within 7 days (up to 7.1%; 95% CI 5.5% to 8.7%). In contrast, NHS 111 and GP referrals were associated with shorter stays, lower breach rates and fewer reattendances. Minimal variation in outcomes was observed across deprivation levels once referral source was accounted for.

Inequalities in how patients access emergency care, particularly reduced GP and NHS 111 referrals among more deprived groups, appear to underpin disparities in ED outcomes. Referral source captures important clinical and system-level factors that influence patient experience and resource use. Interventions to improve equitable access to structured referral pathways, particularly in more deprived areas, may enhance both the efficiency and fairness of emergency care delivery. Further research using national data is needed to assess broader policy implications and economic costs associated with differential access.

To evaluate the association between metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic-associated steatohepatitis (MASH), and the risk of colorectal cancer (CRC) and benign colorectal neoplasms (BCN), and to explore whether liver fibrosis/cirrhosis modifies these associations.

Retrospective cohort study with 1:1 propensity score matching.

Global, multicentre real-world analysis using deidentified electronic health records from over 130 healthcare organisations in the TriNetX Global Collaborative Network.

Hospitalised adults aged 45–75 years between October 2019 and October 2024. Patients with prior diagnoses of colorectal neoplasia or other chronic liver diseases were excluded. Final matched cohorts included 138 902 MASLD and non-MASLD patients, 3715 MASH and non-MASH patients, and 1312 MASH patients with and without fibrosis.

Primary outcomes: Incidence of CRC and BCN. Secondary outcome: Combined incidence of CRC and BCN. Outcomes were assessed with and without controlling for metabolic risk factors using Cox proportional hazards models.

MASLD was associated with increased risks of CRC (HR 2.71, 95% CI 2.29 to 3.20) and BCN (HR 2.50, 95% CI 2.38 to 2.63), both p

MASLD and MASH are independent risk factors for CRC and BCN, irrespective of metabolic comorbidities. Fibrosis/cirrhosis does not significantly influence CRC risk. These findings support the need to revisit CRC screening guidelines for patients with MASLD/MASH. Further prospective studies are warranted to explore underlying mechanisms and evaluate preventative interventions.

Type 1 diabetes is characterised by progressive loss of pancreatic beta cells. Studies have shown that interleukin (IL)–17 is likely a mediator for this destruction. Whether inhibition of IL-17 could preserve beta cell function in people with new-onset type 1 diabetes is unknown.

In this phase 2, randomised, multicentre, placebo-controlled, double-blind trial conducted at 17 study sites in Sweden, 127 adults aged 18–45 years old with newly diagnosed type 1 diabetes will be enrolled. Participants will be randomised to receive either subcutaneous IL-17 inhibitor or placebo for 52 weeks, in addition to their conventional therapy. The primary endpoint will be change in residual insulin secretion measured by the area under the curve for C-peptide in response to 2-hour mixed meal tolerance test between baseline and week 52. Additionally, masked continuous glucose monitoring will be performed during 14 days at the run-in period, week 13, week 26 and week 52. Secondary endpoints will be change in time in glucose range (3.9–10 mmol/L), time in hypoglycaemia (

Approvals were obtained from the Swedish Ethical Review Authority (Dnr 2020–05098) and the Swedish Medical Products Agency (Dnr 5.1-2021-105808) before participant enrolment. Participants provide informed consent before inclusion. Results of this study will be submitted for publication in international peer-reviewed journals and key findings will be presented at international scientific conferences.

To assess the validity of the International Classification of Diseases, 10th Revision (ICD-10) healthcare database diagnosis codes for lithium toxicity at hospital admission in Ontario, Canada.

Population-based retrospective validation study.

A total of 152 hospitals linked to a provincial laboratory database in Ontario, Canada, from 2007 to 2023.

Patients 50 years of age or older taking lithium with hospital-based serum lithium laboratory measurements during admission to the hospital (n=2804).

Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) comparing an ICD-10 diagnostic coding algorithm for lithium toxicity to a serum lithium concentration of 1.5 mmol/L or more. The codes used in the algorithm were T568, T435, Y495, X41 and X49. Serum lithium values and changes in the concentration of serum lithium from baseline levels in patients with and without a diagnosis code for lithium toxicity (code-positive and code-negative, respectively).

The sensitivity of the ICD-10 coding algorithm for identifying a serum lithium level≥1.5 mmol/L was 84% (95% CI 81% to 87%). The specificity and the NPV were over 88%, and the PPV was 63% (95% CI 60% to 66%). The median (IQR) serum lithium measurement in code-positive patients was 1.7 (1.2 to 2.2) mmol/L, and it was 0.6 (0.4 to 0.9) mmol/L in code-negative patients. The median (IQR) increase in serum lithium concentration compared with the most recent prehospital baseline values was 0.7 (0.2 to 1.3) mmol/L in code-positive patients and 0.0 (–0.2 to 0.2) mmol/L in code-negative patients.

In Ontario, the sensitivity of the ICD-10 coding algorithms was moderate for identifying a serum lithium level≥1.5 mmol/L at hospital admission. The presence or absence of the ICD-10 codes for lithium toxicity at hospital admission successfully differentiated two groups of patients with distinct serum lithium measurements.

Patient and family engagement in patient safety in low- and lower-middle-income countries (LLMICs) is not well described. This scoping review synthesised the literature to identify key strategies, barriers and enablers of engagement and to explain how patients and families contribute to safety efforts in healthcare settings.

Scoping review following Arksey–O’Malley and reported per Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

PubMed, Medline, CINAHL, PsycINFO, Scopus and Web of Science were searched from inception to April 2024.

We included qualitative, quantitative and mixed-methods studies, published in English across all healthcare settings, that met the following criteria: (1) explored the attitudes, perceptions and experiences of patients, families or healthcare providers (HCPs) regarding patient engagement in safety activities; (2) described the participation of patients, caregivers or families in the design, delivery or evaluation of interventions aimed at promoting patient safety in healthcare facilities.

Data were extracted using a standardised charting form, and a narrative synthe.sis was conducted to identify key themes. The National Health Service (NHS) framework for patient engagement in patient safety was applied to categorise forms of engagement (information, involvement and partnership) and levels of engagement (own care, service provider and system) among included studies.

Of 7709 records screened, 36 studies met inclusion criteria. Twenty-three studies explored the perspectives of patients, families and HCPs on patient engagement in safety. Key findings revealed that while patients and families recognised the importance of their roles in safety, unclear role definitions, lack of training and communication barriers limited their participation. HCPs acknowledged the value of patient involvement but identified challenges such as knowledge gaps, time constraints and lack of institutional support. Thirteen studies involved patients and family caregivers in safety improvement initiatives. Most interventions were limited to information sharing, with only two achieving partnership-level engagement. Engagement primarily occurred at the individual and provider levels, with no studies addressing the policy level. Factors influencing engagement were identified at four levels: patient, HCP, system and community.

Despite its potential benefits, the implementation and impact of patient and family engagement in patient safety efforts in LLMICs remain largely unexplored. Most efforts focus on information sharing through educational interventions at the direct care level, with limited involvement of patients and families at the partnership level. To enhance safety outcomes, future initiatives must adopt context-specific strategies that empower patients and families as active partners. Drawing lessons from high-income countries and adapting them to the socio-cultural and infrastructural realities of LLMICs will be crucial for developing scalable, cost-effective and sustainable engagement practices.

To enhance the quality of surgical care, complications need to be minimised. Consequently, comprehending the occurrence and risk elements for postoperative complications is essential. Subsequently, we will apply machine learning (ML) algorithms to build risk factor prediction models that will assist surgeons in identifying the risk factors associated with the development of postoperative complications after general surgery.

This research will take place at a tertiary referral medical centre located in Bandar Abbas, Hormozgan, Iran. The inclusion criteria are (1) individuals aged 18 years or older who have any type of general surgery and (2) hospitalised from September 2025 to September 2026. Individuals with insufficient data will be excluded. The main outcomes of the study are complications within 30 days of surgery. Patients will be divided into two groups based on whether they develop complications or not. The predictors are classified as (1) patient-related factors, (2) surgery-related factors and (3) postoperative factors. We intend to detect postoperative complications following general surgery using four distinct supervised ML techniques: (1) logistic regression, (2) decision trees, (3) random forests and (4) extreme gradient boosting. Accuracy, precision, recall and F1 score will be used to evaluate the performance of ML models.

With approval from the Hormozgan University of Medical School Research Ethics Board (IR.HUMS.REC.1404.137), we will carry out a forward-looking analysis of the medical records of patients undergoing general surgery. We will obtain informed consent, and all information will be collected and examined anonymously. The findings of this research will be released in appropriate scientific publications.

The Maharashtra Anaemia Study 3 (MAS 3) aims to (1) Investigate the nutritional, environmental, and economic impacts on haemoglobin concentration/anaemia, (2) Identify the underlying micronutrient causes of anaemia and (3) Investigate the association between anaemia and physical and cognitive development of Indian children during their first 18 years of life. This paper introduces the MAS 3 cohort, which consists of data collected from the participants in the prospective Pune Maternal Nutrition Study from the antenatal period to children at 18 years of age (1996–2014) in the Maharashtra state, India.

Recruitment of 2466 married non-pregnant women, and their husbands, took place between June 1994 and April 1996 in six villages, approximately 50 km from Pune city in India. Women were followed up monthly to identify those who became pregnant. A total of 797 pregnant women were followed up for data collection at or near gestational week 18 and 28, with further data collection for women and children occurring within 72 hours of delivery, for both live and stillbirths. Of the 797 women, 710 were included in the MAS 3 cohort, and long-term follow-up of children occurred at 6 years, 12 years and 18 years of age.

In the MAS 3 cohort, most mothers (73%) were aged between 18 and 25 years at the time of their final prepregnancy visit (baseline), and half (55%) belonged to families of middle-upper socioeconomic status (SES). At the children’s baseline (birth) visit, children had a mean birth weight of 2630 g (SD: 376), with one third (31%) of low birth weight. At the 6-year, 12-year and 18-year follow-up visits, data were available for 706 (99%), 689 (97%) and 694 (98%) children.

MAS 3 will be used to address a number of research objectives, including (1) Trends of haemoglobin and anaemia-related micronutrients from age 6 to 18 years, (2) Micronutrient causes of anaemia during childhood, (3) Prevalence and risk factors for maternal anaemia and childhood anaemia, (4) Impact of maternal anaemia on immediate birth outcomes and (5) Intergenerational risk factors associated with anaemia.

To evaluate the associations between anthropometric indices and components of metabolic syndrome (MetS), including blood pressure, fasting blood sugar (FBS), triglycerides, high-density lipoprotein cholesterol and waist circumference (WC) in Iranian adults.

Cross-sectional analysis of baseline data from a population-based cohort.

Fasa adults’ cohort study, a rural community-based cohort in Fars province, Iran.

A total of 1550 adults aged 35–70 years with MetS, identified from among 10 118 cohort participants using the National Cholesterol Education Programme Adult Treatment Programme III criteria.

The anthropometric indices include abdominal volume index (AVI), a body shape index (ABSI), atherogenic index of plasma (AIP), body roundness index (BRI), body adiposity index (BAI), conicity index, ponderal index and visceral adiposity index (VAI).

Participants (56.1% female) with a mean age of 49.8±9.5 years. AVI was significantly associated with systolic blood pressure (SBP) (β=0.010, p

Anthropometric indices, including VAI, AIP, BAI, BRI and AVI, exhibit significant associations with key components of MetS in Iranian adults, particularly blood pressure, glycaemic markers and central adiposity. Among these, BAI showed the strongest correlation with MetS parameters, while ABSI displayed the weakest.

A retrospective cohort study.

A large multispecialty, tertiary referral and teaching hospital in England, UK.

The study included 3175 consecutive adult ICU UPAs from hospital wards over a 6-year period (2014–2019).

Ward-based management of deterioration prior to ICU admission was assessed by the RRT, using a scored checklist—the UPA score. Admissions were compared in two groups according to their exposure to an RRT review in the 72 hours before ICU admission. Associations with in-hospital cardiac arrest within 24 hours before ICU admission and all-cause in-hospital mortality were estimated, using unadjusted and adjusted odds ratios (aORs) with 95%CI.

RRT review occurred in 1413 (44.5%) admissions and was associated with reduced odds of in-hospital cardiac arrest (aOR 0.51; 95% CI 0.36 to 0.78; p

An RRT review in the 72 hours prior to ICU admission was associated with reduced odds of in-hospital cardiac arrest but did not impact in-hospital mortality. Higher UPA scores were associated with increased incidence of both in-hospital cardiac arrest and in-hospital mortality. In addition, this study describes a novel and adaptable RRT scoring tool (the UPA score) for safety monitoring and quality improvement.

Prolonged QTc is a major risk factor for ventricular arrhythmias and sudden cardiac death (SCD). Anaemia’s impact on the QT interval is unclear and conflicting despite its association with increased mortality.

We investigated the association between anaemia and the prevalence of QTc prolongation, as well as potential gender differences in this relationship. Additionally, we examined whether haemoglobin levels were associated with QTc prolongation.

Observational cross-sectional study.

Sheshdeh, Fasa, Iran.

We analysed data from 5741 participants from the general population (aged 35–70 years) with no history of ischaemic heart disease; myocardial infarction; amiodarone use; multiple blood transfusions; or supplementation with iron, folic acid or cobalamin.

Anaemia was defined according to WHO guidelines (haemoglobin 450 ms in men or >470 ms in women.

Among 5741 participants, mean QTc was 427.91±24.75 ms, with QTc prolongation in 7.14%. Anaemia raised the odds of QTc prolongation by 60% (OR=1.60, 95%CI 1.12 to 2.28, p=0.010), particularly in females (OR=1.73, 95%CI 1.12 to 2.66, p=0.013), but not in males. Higher haemoglobin levels were associated with lower QTc prolongation risk (OR=0.91 per unit increase, 95% CI 0.85 to 0.97, p=0.005). No significant associations were observed between anaemia type/severity and QTc prolongation among anaemic individuals.

Anaemia was significantly associated with QTc prolongation, particularly in females. Anaemia type/severity did not affect QTc prolongation. Anaemia is associated with increased odds of QTc prolongation, particularly in women. While causality cannot be inferred from this cross-sectional analysis, the findings suggest that clinicians may consider QTc monitoring in anaemic patients, especially women and exercise caution when prescribing QT-prolonging medications. Prospective studies are needed to confirm whether anaemia directly contributes to QTc prolongation or arrhythmic risk.

The study was conducted to assess the diagnostic performance of the Hightop Syphilis Rapid Diagnostic Test (RDT) in comparison with the ELISA test used as a reference method.

A laboratory-based cross-sectional and comparative study was conducted to assess the diagnostic performance of the Hightop Syphilis RDT.

Blood samples obtained from adult participants in eight health facilities were analysed at the National Public Health Laboratory (NPHL), Ministry of Public Health, Yaounde, Cameroon.

From 29 April to 25 August 2023, 583 adult participants of both sexes (aged ≥21 years), including both syphilis positive and syphilis negative, were recruited consecutively in eight health facilities in eight regions of Cameroon.

Blood samples were screened for the detection of anti-Treponema pallidum antibodies using the One Step Rapid Test (Qingdao Hightop Biotech), a non-treponemal test and ELISA (Biorex Diagnostics, UK), a treponemal test used as a reference method. Diagnostic performance of the Syphilis RDT was analysed using Epi Info V.7 and validated through online statistical tools such as StatPages, GraphPad, QuickCalcs and MedCalc software.

Of the 583 samples tested, the Hightop Syphilis RDT revealed a sensitivity of 84.6% (95% CI: 74.8% to 91.1%) and specificity of 98.5% (95% CI: 97.5% to 99.1%). The positive predictive value (PPV) and negative predictive value (NPV) were 84.6% (95% CI: 74.8% to 91.1%) and 98.5% (95% CI: 97.5% to 99.1%), respectively. Regarding the stratification of diagnostic performance by clinical stage, the test showed a sensitivity of 100.0% (95% CI: 71.51% to 100.0%) and specificity of 99.06% (95% CI: 94.86% to 99.98%). The PPV and NPV were 91.67% (95% CI: 61.00% to 98.72%) and 100.0% (95% CI: 96.55% to 100.0%), respectively, in symptomatic individuals. Among asymptomatic individuals, sensitivity was 97.56% (95% CI: 87.14% to 99.94%) and specificity was 100.0% (95% CI: 99.14% to 100.0%). The PPV and NPV were 100.0% (95% CI: 91.19% to 100.0%) and 99.77% (95% CI: 98.40% to 99.97%), respectively.

The Hightop Syphilis RDT demonstrated adequate diagnostic performance, particularly among symptomatic individuals, supporting its utility as a reliable tool for syphilis detection in clinical settings.

Musculoskeletal disorders (MSDs) in the workplace are a major health problem which is significantly related to the adverse effects on the workforce’s health in different occupations, including the petrochemical industry employees. Many health behaviors can play a significant role in preventing complications caused by MSDs; however, in developing countries such as Iran, there is a lack of clarity about the factors affecting the prevention of complications from these disorders from the perspective of petrochemical industry employees. This study aimed to investigate effective factors to prevent complications caused by MSDs in petrochemical industry workers in Iran.

This qualitative study was conducted using the conventional content analysis method. The data were collected using in-depth and unstructured interviews with 23 employees and managers of the petrochemical industry. In this study, the participants were selected from different industry centres using the purposeful sampling method and based on the maximum diversity (work duties, age, level of education). The collected data were then analysed using the initial matrix developed based on the available literature.

The analysis of the data from 23 interviews resulted in the identification of four main categories: educational-consultative support, organisational-management structure transformation, infrastructure security and physical environment redesign, and self-care necessity. These categories are the primary factors that influence the preventive behaviours related to MSDs among employees in the petrochemical industry.

The concepts that have emerged based on the results of this study can potentially help to develop comprehensive and appropriate training and health promotion programmes in creating, maintaining and promoting preventive behaviours of complications caused by MSDs in petrochemical industry workers.

Osteoporosis is a skeletal condition with decreased bone mass and structural deterioration, increasing fracture vulnerability. Several studies have found a correlation between prostate cancer in men and an increased risk of osteoporosis. This study aims to determine the prevalence of osteoporosis in patients with prostate cancer.

The primary objective of this study will be to estimate the prevalence of osteoporosis in prostate cancer survivor patients. An extensive search will be conducted on PubMed, Scopus, Embase, Web of Science, CINAHL and ProQuest databases to ensure comprehensive coverage. The search will encompass the timeframe from 1 January 1994 to 24 September 2024. Furthermore, we will not impose any limitations on the language or geographical location of the published studies. In order to assess the potential bias in the included studies, the Joanna Briggs Institute critical appraisal checklist for prevalence studies will be employed. The analysis of data will be performed using STATA V.17. The prevalence of osteoporosis or osteopenia will be calculated for each study by dividing the number of participants with these conditions by the total number of patients diagnosed with prostate cancer. A subgroup analysis will examine prevalence regarding geographical location, age groups, ethnicity, definitions and measurements of osteoporosis or osteopenia, risk of bias in the included studies, type and duration of androgen deprivation therapy, and site of osteoporosis diagnosis. We will employ multiple methods to detect publication bias, including funnel plot analysis, Begg’s and Egger’s tests, and the Trim and Fill method. If we have enough data, we will conduct a sensitivity analysis using the leave-one-out-remove method.

No ethical approval or patient consent is required as this study synthesises only published aggregate data. Results will be disseminated via a peer-reviewed publication.
