Moving towards an equitable future: Rethinking the use of race in pediatric densitometry.

Current guidelines from the International Society for Clinical Densitometry (ISCD) recommend considering race, sex, and age in calculating pediatric bone density z-scores by Dual-Energy X-ray Absorptiometry (DXA). However, as patient populations become increasingly diverse, the application of these guidelines presents significant challenges, potentially leading to racial bias and systemic inequities in care. In response to growing calls for a reevaluation of race's role in clinical decision-making, we aimed to assess the readiness of front-line providers of DXA services to address these challenges.

Development and Videographic Evaluation of a Vascular Access Simulation-Based Curriculum for Surgical and Medical Trainees.

Background: There is a paucity of data evaluating femoral arterial access training, despite significant morbidity/mortality associated with incorrect femoral arterial access. The aim of this study was to develop and evaluate a novel 2-component simulation-based curriculum to address a lack of standardized access training and identify the most frequent errors in access.

Methods: The femoral arterial access curriculum was developed through a multi-disciplinary collaboration and utilized in-person simulation sessions in conjunction with online and in-person didactic training.

Task-sharing spinal anaesthesia care in three rural Indian hospitals: a non-inferiority randomised controlled clinical trial.

Background: Task-sharing of spinal anaesthesia care by non-specialist graduate physicians, termed medical officers (MOs), is commonly practised in rural Indian healthcare facilities to mitigate workforce constraints. We sought to assess whether spinal anaesthesia failure rates of MOs were non-inferior to those of consultant anaesthesiologists (CA) following a standardised educational curriculum.

Methods: We performed a randomised, non-inferiority trial in three rural hospitals in Tamil Nadu and Chhattisgarh, India.

Giant polyketide synthase enzymes in the biosynthesis of giant marine polyether toxins.

are harmful haptophyte algae that cause massive environmental fish kills. Their polyketide polyether toxins, the prymnesins, are among the largest nonpolymeric compounds in nature and have biosynthetic origins that have remained enigmatic for more than 40 years. In this work, we report the "PKZILLAs," massive polyketide synthase (PKS) genes that have evaded previous detection.
