Early achievement of hemostasis defined by transfusion velocity: A possible mechanism for whole blood survival benefit.

Introduction: Whole blood resuscitation is associated with survival benefits in observational cohort studies. The mechanisms responsible for outcome benefits have not been adequately determined. We sought to characterize the achievement of hemostasis across patients receiving early whole blood versus component resuscitation.

High-grade liver injury: outcomes with a trauma surgery-liver surgery collaborative approach.

Background: Operative mortality for high-grade liver injury (HGLI) remains 42% to 66%, with near-universal mortality after retrohepatic caval injury. The objective of this study was to evaluate mortality and complications of operative and nonoperative management (OM and NOM) of HGLI at our institution, characterized by a trauma surgery-liver surgery collaborative approach to trauma care.

Methods: This was an observational cohort study of adult patients (age ≥16) with HGLI (The American Association for Surgery of Trauma (AAST) grades IV and V) admitted to an urban level I trauma center from January 2010 to November 2021.

Early Cold Stored Platelet Transfusion Following Traumatic Brain Injury: A Randomized Clinical Trial.

Objective: To determine the feasibility, efficacy, and safety of cold stored compared to room temperature platelet transfusion in patients with traumatic brain injury.

Summary Background Data: Data demonstrating the safety and efficacy of cold stored platelet transfusion are lacking following traumatic brain injury.

Methods: A phase 2, randomized, open label, clinical trial was performed at a single U.

Fishers and First Responders: Oil Spill Safety Workshop Design and Evaluation.

Objectives: This paper describes the design and evaluation of a workshop created to develop safer disaster response strategies for fishing communities, using the 2019 Northeast Brazil Oil Spill as a starting point for community-engaged education.

Methods: The 3-day pilot workshop included presentations, structured discussions, and interactive activities with small-scale fishers (SSFs), university researchers, and representatives of local government agencies. The workshop was evaluated through a mixed-method approach that considered qualitative data from discussion groups, collectively built products, and content retention.

Assessing Lung Ventilation and Bronchodilator Response in Asthma and Chronic Obstructive Pulmonary Disease with F MRI.

Background Pulmonary function tests are central to diagnosis and monitoring of respiratory diseases but do not provide information on regional lung function heterogeneity. Fluorine 19 (F) MRI of inhaled perfluoropropane permits quantitative and spatially localized assessment of pulmonary ventilation properties without tracer gas hyperpolarization. Purpose To assess regional lung ventilation properties using F MRI of inhaled perfluoropropane in participants with asthma, participants with chronic obstructive pulmonary disease (COPD), and healthy participants, including quantitative evaluation of bronchodilator response in participants with respiratory disease.
