Differential attainment at national selection for higher surgical training: a retrospective cohort study.

Objectives: National selection for higher surgical specialty training (HST) in the UK is a high-stakes gatekeeping assessment. If barriers, such as differential attainment, exist at HST selection for some groups and not others, then this will have a significant and lasting impact on trainees' career progression and the diversity of the workforce, which should reflect the population it provides care for. The objective of this study was to characterise the relationship between candidate sociodemographic factors and performance at National Selection for HST in the UK.

Systematic review and meta-analysis of the pelvic organ prolapse and vaginal prolapse among the global population.

Background: Pelvic organ prolapse (POP) occurs when one or more pelvic organs (uterus, bowel, bladder or top of the vagina) descend from their normal position and bulge into the vagina. Symptoms include pelvic discomfort, fullness, and changes in bladder or bowel function. Treatment ranges from conservative approaches to surgery, depending on symptom severity.

The promise of community-driven preprints in ecology and evolution.

Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Hyperhomocysteinemia-associated Thrombosis in Patients With Pernicious Anemia.

Introduction: Cobalamin deficiency (CD) due to pernicious anemia (PA) leads to hyperhomocystinemia, a risk factor for thrombosis. However, the clinical presentations and outcomes of hyperhomocystinemia-associated thrombosis (HAT) are not fully understood.

Methods: We undertook a literature search using PUBMED, SCOPUS and WEB OF SCIENCE databases for the terms "pernicious anemia AND thrombosis", "pernicious anemia AND embolism", "pernicious anemia AND thromboembolism", "autoimmune gastritis AND thrombosis", "autoimmune gastritis AND embolism", "autoimmune gastritis AND thromboembolism" through January 2024 and reviewed the published literature.

Poor agreement among asthma specialists on the choice and timing of initiation of a biologic treatment for severe asthma patients.

Background: As the number of monoclonal antibodies available for severe asthma is growing, specialists currently choose without clear guidelines. Despite increasing knowledge on treatment response to these monoclonal antibodies, making the optimal choice for each individual patient remains a challenge. However, evidence of this daily challenge is lacking.

Clinical Utility of Systolic Left Ventricular Ejection Fraction in Atrial Fibrillation: Role of Prospective ECG-Triggered Cardiac CT.

Background: The assessment of left ventricular (LV) systolic function and quantification of LV ejection fraction (EF) in patients with atrial fibrillation (AF) can be difficult. We previously demonstrated that LV volume changes over the 100 ms of systole (LVEF) can be used as a measure of LV systolic function.

Objective: We sought to evaluate the applicability of LVEF in AF patients.

Extreme heat risk and the potential implications for the scheduling of football matches at the 2026 FIFA World Cup.

Climate change is making extreme heat events more frequent and intense. This negatively impacts many aspects of society, including organised sport. As the world's most watched sporting event, the FIFA World Cup commands particular attention around the threat of extreme heat.

Biochemical osteomalacia in adults undergoing vitamin D testing in the North-East of Scotland.

Background: International guidelines give greatly varying definitions of 25-hydroxyvitamin D (25OHD) insufficiency and deficiency. Vitamin D testing is increasing despite 2016 UK guidance for adults advising routine vitamin D supplementation October-March and year-round for high risk groups. A service evaluation of vitamin D testing and biochemical osteomalacia in the North-East of Scotland (57-58°N) could inform definitions and testing guidance.

Differences in Brain Volume and Thickness between Shammah (Smokeless Tobacco) Users and Non-Users: A Cross-Sectional Study.

Previous research has shown that smoking tobacco is associated with changes or differences in brain volume and cortical thickness, resulting in a smaller brain volume and decreased cortical thickness in smokers compared with non-smokers. However, the effects of smokeless tobacco on brain volume and cortical thickness remain unclear. This study aimed to investigate whether the use of shammah, a nicotine-containing smokeless tobacco popular in Middle Eastern countries, is associated with differences in brain volume and thickness compared with non-users and to assess the influence of shammah quantity and type on these effects.

Measuring the effect of RFID and marker recognition tags on cockroach (Blattodea: Blaberidae) behavior using AI-aided tracking.

Radio frequency identification (RFID) technology and marker recognition algorithms can offer an efficient and non-intrusive means of tracking animal positions. As such, they have become important tools for invertebrate behavioral research. Both approaches require fixing a tag or marker to the study organism, and so it is useful to quantify the effects such procedures have on behavior before proceeding with further research.

Transcriptomic Evidence Reveals the Dysfunctional Mechanism of Synaptic Plasticity Control in ASD.

Background/objectives: A prominent endophenotype in Autism Spectrum Disorder (ASD) is the synaptic plasticity dysfunction, yet the molecular mechanism remains elusive. As a prototype, we investigate the postsynaptic signal transduction network in glutamatergic neurons and integrate single-cell nucleus transcriptomics data from the Prefrontal Cortex (PFC) to unveil the malfunction of translation control.

Methods: We devise an innovative and highly dependable pipeline to transform our acquired signal transduction network into an mRNA Signaling-Regulatory Network (mSiReN) and analyze it at the RNA level.

Segmental analysis of human hair reveals intra-annual variation in 25(OH)D concentrations in modern and archaeological individuals.

Vitamin D is essential for healthy skeletal growth and is increasingly recognised for its role in chronic disease development, inflammation and immunity. 25-hydroxyvitamin D (25(OH)D) concentrations are an indicator of vitamin D status and are normally analysed in plasma or serum samples in clinical settings, while archaeological studies rely on the identification of skeletal markers of vitamin D deficiency, such as rickets. Here, we determined 25(OH)D concentrations in hair specimens ('locks') that had been sampled close to the root, aligned by cut end, and sliced into sequential segments from participants (n = 16), from Aberdeen, Scotland, using a modified protocol designed to minimise sample size.

Transitions in intensive care: Investigating critical slowing down post extubation.

Complex biological systems undergo sudden transitions in their state, which are often preceded by a critical slowing down of dynamics. This results in longer recovery times as systems approach transitions, quantified as an increase in measures such as the autocorrelation and variance. In this study, we analysed paediatric patients in intensive care for whom mechanical ventilation was discontinued through removal of the endotracheal tube (extubation).

Association and substitution analyses of dietary sugars, starch and fiber for indices of body fat and cardiometabolic risk- a NoHoW sub-study.

Purpose: To examine the associations and substitutions of dietary sugars [extrinsic (free) or intrinsic (non-free)] as well as dietary starch and fiber intakes for indices of body fat and cardiometabolic health.

Methods: Dietary intake was assessed at multiple times using multi-day 24-hour recalls over 18-months for indices of body fat (body fat %, waist circumference, BMI, and weight change) (n = 1066) and at baseline and 12 months for cardiometabolic outcomes (LDL, HDL, HbA1c) (n = 736). Bayesian modeling was applied to analyze the probabilistic impact of dietary carbohydrate components using credible intervals for association and substitution analyses with repeated measures random effects modeling.
