Postoperative atrial fibrillation following cardiac surgery in severe obesity: the added value of waist circumference.

Introduction: Obesity is an independent risk factor for postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) surgery. POAF in patients with severe obesity (body mass index [BMI] ≥ 35 kg/m) is less studied. Whether waist circumference (WC) improves prediction of POAF independently of BMI among patients with severe obesity remains unknown.

Paving the way for quality assured, decentralised point-of-care testing for infectious disease in primary care - Real world lessons from remote Australia.

Introduction: Decentralized molecular testing for infectious disease diagnosis at the point-of-care (POC) is critical to address inequities in access to timely, informed health care. The COVID-19 pandemic accelerated the demand, development and adoption of POC tests for infectious diseases globally. This has provided opportunities to maximize the individual benefits and public health impact of POC testing, particularly in remote and resource-limited primary care settings.

Enzymatic epimerization of monoterpene indole alkaloids in Kratom.

Monoterpene indole alkaloids (MIAs) are a large, structurally diverse class of bioactive natural products. These compounds are biosynthetically derived from a stereoselective Pictet-Spengler condensation that generates a tetrahydro-β-carboline scaffold characterized by a 3 stereocenter. However, a subset of MIAs contain a non-canonical 3 stereocenter.
