Leaving orthopaedic surgical training: the LOST surgeons - a qualitative study exploring why UK trauma and orthopaedic registrars discontinue surgical training

Objectives The study aimed to explore why trauma and orthopaedic registrars decide to discontinue surgical training. Understanding the factors that influence a decision to leave may help to inform changes which enhance the experiences of surgeons and retention of the future workforce. Design Qualitative study using semi-structured interviews. Setting Between October 2022 and March 2026, interviews were conducted with participants who had left the UK National Health Service (NHS) trauma and orthopaedic specialty training before completion. Reflexive thematic analysis was performed on 1727 min…

The effects of intravenous iron on mobility in older adults following hip fracture surgery: protocol for a multicentre, parallel group, randomised controlled trial - the IronHip trial

Introduction Half of all patients with a hip fracture (HF) do not recover their pre-fracture mobility after 1 year. Mobility and functional capabilities may be impaired by postoperative low haemoglobin levels and iron deficiency. The primary objective of this trial is to compare the effect of a single postoperative dose of ferric derisomaltose 20 mg/kg body weight relative to placebo on the recovery of functional mobility in patients. Methods and analysis The IronHip trial is a multicentre, randomised, double-blind, placebo-controlled trial with participants allocated in a 1:1 ratio to receive…

Cardiovascular and renal outcomes of combined SGLT2 inhibitors and GLP-1 receptor agonists versus monotherapy in patients with type 2 diabetes mellitus: a network meta-analysis

Background: Whether using both sodium–glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) is more effective than using either alone in type 2 diabetes mellitus remains uncertain. We sought to assess cardiovascular and kidney outcomes of combined SGLT2i and GLP-1RA therapy versus monotherapy using network meta-analysis. Methods: We identified randomized controlled trials (RCTs) of SGLT2i or GLP-1RA in patients with type 2 diabetes mellitus through a comprehensive search of MEDLINE, Embase, and the Cochrane Library until Aug. 15, 2025. We compared…

Age, Multidomain Lifestyle Intervention, and White Matter Integrity

This prespecified secondary analysis of a randomized clinical trial assesses whether a multidomain lifestyle intervention, vs a self-guided program, alters trajectories of cerebrovascular magnetic resonance imaging (MRI) markers, whether baseline diffusion MRI estimates subsequent vascular injury, and whether any effects differ by age among adults 60 to 79 years of age who are at increased risk for cognitive decline.
