Evaluation of Insulin Dosing Strategies for Hyperkalemia Management at an Academic Medical Center.

Purpose: While intravenous (IV) insulin is often administered at a fixed dose of 10 units for acute hyperkalemia, optimal dosing for minimizing hypoglycemia while effectively reversing hyperkalemia has not been established. The purpose of this analysis was to evaluate the effect of insulin dosing strategies on hypoglycemia in patients with hyperkalemia.

Methods: Adult patients presenting to an academic medical center who received IV insulin for hyperkalemia between 2016 and 2020 were retrospectively identified.

Prevalence, risk factors, and outcomes associated with delayed second doses of antibiotics in sepsis at a large academic medical center.

Objective: To evaluate the prevalence, risk factors, and clinical impact of delays in second doses of antibiotics in patients with sepsis.

Design: Single-center, retrospective, observational study.

Setting: Large teaching hospital.

Post-transcriptional suppression of pathogenic prion protein expression in Drosophila neurons.

A wealth of evidence supports the view that conformational change of the prion protein, PrPC, into a pathogenic isoform, PrPSc, is the hallmark of sporadic, infectious, and inherited forms of prion disease. Although the central role played by PrPSc in the pathogenesis of prion disease is appreciated, the cellular mechanisms that recognize PrPSc and modulate its production, clearance, and neural toxicity have not been elucidated. To address these questions, we used a tissue-specific expression system to express wild-type and disease-associated PrP molecules heterologously in Drosophila melanogaster.
