Metabolic bariatric surgery generates substantial, sustained weight loss and health improvement in a real-world setting.

Background: To determine if the positive outcomes from clinical trials regarding the safety and efficacy of metabolic bariatric surgery are reproducible at a national level.

Methods: A longitudinal registry-based observation study with data collected from all persons undergoing metabolic bariatric surgery in Australia from 28 February 2012-31 December 2021 including data from 122,567 index patients who underwent 134,625 completed bariatric procedures.

Main Outcomes And Measures: Defined adverse outcomes at 90-days (unplanned readmission, intensive care admission and re-operation; death), annual change in weight (percent total body weight loss (TBWL)), diabetes treatment and need for re-operation.

Foxm1 promotes differentiation of neural progenitors in the zebrafish inner ear.

During development of the vertebrate inner ear, sensory epithelia and neurons of the statoacoustic ganglion (SAG) arise from lineage-restricted progenitors that proliferate extensively before differentiating into mature post-mitotic cell types. Development of progenitors is regulated by Fgf, Wnt and Notch signaling, but how these pathways are coordinated to achieve an optimal balance of proliferation and differentiation is not well understood. Here we investigate the role in zebrafish of Foxm1, a transcription factor commonly associated with proliferation in developing tissues and tumors.

A Qualitative Exploration of Student Cognition When Answering Text-Only or Image-Based Histology Multiple-Choice Questions.

Unlabelled: Interpretation of images and spatial relationships is essential in medicine, but the evidence base on how to assess these skills is sparse. Thirty medical students were randomized into two groups (A and B), and invited to "think aloud" while completing 14 histology MCQs. All students answered six identical MCQs, three with only text and three requiring image interpretation.

A psychological model of predictive factors of distress following long COVID.

Background: Long COVID, described as "the continuation or development of new symptoms 3 months after the initial SARS-CoV-2 infection", is estimated to affect at least 10-20 % of all cases of acute SARS-CoV-2 infection. Because of its novelty, information regarding the experience of Long COVID is still emerging.

Methods: This study examines psychological distress in two long COVID populations, and their experience of fatigue, cognitive failures, experiential avoidance, rumination, and perceived injustice.
