Development of Optimized Tissue-Factor-Targeted Peptide Amphiphile Nanofibers to Slow Noncompressible Torso Hemorrhage.

Noncompressible torso hemorrhage accounts for a significant portion of preventable trauma deaths. We report here on the development of injectable, targeted supramolecular nanotherapeutics based on peptide amphiphile (PA) molecules that are designed to target tissue factor (TF) and, therefore, selectively localize to sites of injury to slow hemorrhage. Eight TF-targeting sequences were identified, synthesized into PA molecules, coassembled with nontargeted backbone PA at various weight percentages, and characterized circular dichroism spectroscopy, transmission electron microscopy, and X-ray scattering.

Emerging Therapies for Prehospital Control of Hemorrhage.

Background: The aim of this review was to describe emerging therapies that could serve as a prehospital intervention to slow or stop noncompressible torso hemorrhage in the civilian and military settings. Hemorrhage accounts for 90% of potentially survivable military deaths and 30%-40% of trauma deaths. There is a great need to develop novel therapies to slow or stop noncompressible torso hemorrhage at the scene of the injury.

Fellowship or Family? A Comparison of Residency Leave Policies With the Family and Medical Leave Act.

Background: In 1993, the Family and Medical Leave Act (FMLA) mandated 12 weeks of unpaid, job-protected leave. The current impact of taking 12 weeks of leave during residency has not been evaluated.

Methods: We examined the 2018 Accreditation Council for Graduate Medical Education (n = 24) specialty leave policies to determine the impact of 6- and 12-week leave on residency training, board eligibility, and fellowship training.
