High-dose intranasal insulin in an adaptive dose-escalation study in healthy human participants.

Intranasal insulin is a putative neuroprotective therapy after cardiac arrest, but safety in humans at doses extrapolated from animal models is unknown. This phase I, open-label adaptive dose-escalation study explores the maximum tolerated dose of intranasal insulin in healthy human participants. Placebo or insulin at doses from 0 to 1000 units was given to healthy participants intranasally on repeated weekly visits.

T32 programs in emergency medicine: A report from the ACEP-SAEM Federal Research Funding Workgroup.

Advancing care in Emergency Medicine (EM) requires the development of well-trained researchers, but our specialty has lower amounts of research funding compared to similar medical fields. Increasing the number of pathways available for research training supports the growth of new investigators. To address the need for more EM researchers, the Society of Academic Emergency Medicine and the American College of Emergency Physicians convened a Federal Research Funding Workgroup.

Improving Outcomes After Post-Cardiac Arrest Brain Injury: A Scientific Statement From the International Liaison Committee on Resuscitation.

This scientific statement presents a conceptual framework for the pathophysiology of post-cardiac arrest brain injury, explores reasons for previous failure to translate preclinical data to clinical practice, and outlines potential paths forward. Post-cardiac arrest brain injury is characterized by 4 distinct but overlapping phases: ischemic depolarization, reperfusion repolarization, dysregulation, and recovery and repair. Previous research has been challenging because of the limitations of laboratory models; heterogeneity in the patient populations enrolled; overoptimistic estimation of treatment effects leading to suboptimal sample sizes; timing and route of intervention delivery; limited or absent evidence that the intervention has engaged the mechanistic target; and heterogeneity in postresuscitation care, prognostication, and withdrawal of life-sustaining treatments.
