Evolution of sex differences in cooperation can be explained by trade-offs with dispersal.

Explaining the evolution of sex differences in cooperation remains a major challenge. Comparative studies highlight that offspring of the more philopatric sex tend to be more cooperative within their family groups than those of the more dispersive sex but we do not understand why. The leading "Philopatry hypothesis" proposes that the more philopatric sex cooperates more because their higher likelihood of natal breeding increases the direct fitness benefits of natal cooperation.

Adjudication of Hospitalizations and Deaths in the IRONMAN Trial of Intravenous Iron for Heart Failure.

Background: Patients with heart failure and iron deficiency have diverse causes for hospitalization and death that might be affected by iron repletion.

Objectives: The purpose of this study was to explore causes of hospitalizations and deaths in a randomized trial (IRONMAN) of heart failure comparing intravenous ferric derisomaltose (FDI) (n = 568) and usual care (n = 569).

Methods: Patients with heart failure, left ventricular ejection fraction ≤45%, and either transferrin saturation <20% or serum ferritin <100 μg/L were enrolled.

An Approach for Combining Clinical Judgment with Machine Learning to Inform Medical Decision Making: Analysis of Nonemergency Surgery Strategies for Acute Appendicitis in Patients with Multiple Long-Term Conditions.

Background: Machine learning (ML) methods can identify complex patterns of treatment effect heterogeneity. However, before ML can help to personalize decision making, transparent approaches must be developed that draw on clinical judgment. We develop an approach that combines clinical judgment with ML to generate appropriate comparative effectiveness evidence for informing decision making.

Racial disparities in prostate cancer in the UK and the USA: similarities, differences and steps forwards.

In the USA, Black men are approximately twice as likely to be diagnosed with and to die of prostate cancer than white men. In the UK, despite Black men having vastly different ancestral contexts and health-care systems from Black men in the USA, the lifetime risk of being diagnosed with prostate cancer is two-to-three times higher among Black British men than among white British men and Black British men are twice as likely to die of prostate cancer as white British men. Examination of racial disparities in prostate cancer in the USA and UK highlights systemic, socio-economic and sociocultural factors that might contribute to these differences.

Mitochondria-targeted hydrogen sulfide donor reduces atherogenesis by changing macrophage phenotypes and increasing UCP1 expression in vascular smooth muscle cells.

Atherosclerosis is a leading cause of morbidity and mortality in the Western countries. Mounting evidence points to the role of mitochondrial dysfunction in the pathogenesis of atherosclerosis. Recently, it has been shown that mitochondrial hydrogen sulfide (HS) can complement the bioenergetic role of Krebs cycle leading to improved mitochondrial function.

Biomarkers Suitable for Early Detection of Intrathoracic Cancers in Primary Care: A Systematic Review.

Intrathoracic cancers, including lung cancer, mesothelioma, and thymoma, present diagnostic challenges in primary care. Biomarkers could resolve some challenges. We synthesized evidence on biomarker performance for intrathoracic cancer detection in low-prevalence settings.

Exposure effects of synthetic glucocorticoid drugs on skeletal developmental and immune cell function in zebrafish.

Synthetic glucocorticoids (GCs) are used to treat a wide range of human health conditions and as such are frequently detected in the aquatic environment. This, together with the highly conserved nature of the glucocorticoid system across vertebrates means that the potential for biological effects of GCs in fish is relatively high. Here, we found that exposure of zebrafish (Danio rerio) to environmentally relevant concentrations of 4 of the most widely used synthetic GCs (beclomethasone dipropionate, budesonide, fluticasone propionate, and prednisolone), from 0 to 4 days post fertilisation (dpf), resulted in no effects on embryo-larval development or bone and cartilage formation.

Hospital Experiences of Carers in Relation to the Comprehensive Care Standard: A Mixed Method Study.

Aims: To explore the care experiences of informal carers of people with chronic conditions in hospitals and identify areas for improvement in the context of comprehensive care delivery.

Design: A explanatory sequential mixed-method study.

Methods: This study was conducted, involving a survey with 182 carers and interviews with 31 carers of individuals who attended an Australian hospital.

A hybrid framework with large language models for rare disease phenotyping.

Purpose: Rare diseases pose significant challenges in diagnosis and treatment due to their low prevalence and heterogeneous clinical presentations. Unstructured clinical notes contain valuable information for identifying rare diseases, but manual curation is time-consuming and prone to subjectivity. This study aims to develop a hybrid approach combining dictionary-based natural language processing (NLP) tools with large language models (LLMs) to improve rare disease identification from unstructured clinical reports.

Random C-Peptide and Islet Antibodies at Onset Predict β Cell Function Trajectory and Insulin Dependence in Pediatric Diabetes.

Objective: Identification of prognostic biomarkers in pediatric diabetes is important for precision medicine. We assessed whether C-peptide and islet autoantibodies are useful to predict the natural history of children with new-onset diabetes.

Methods: We prospectively studied 72 children with new-onset diabetes (median follow-up: 8 months) by applying the Aβ classification system ("A+": islet autoantibody positive, "β+": random serum C-peptide ≥1.
