Age above all: The impact of storage duration in mice resuscitated with whole blood or packed red blood cells and plasma in a hemorrhagic shock model.

Background: The use of whole blood compared with a balanced ratio of components in trauma resuscitation remains an area of ongoing investigation. One factor that may affect outcomes is the age of the blood product transfused. We used a murine model of blood banking and hemorrhagic shock resuscitation to compare the effect of storage duration in whole blood and packed red blood cells on the recipient inflammatory response.

Perceptions of the White Coat: Generational, Regional, and Gender Differences Among Surgeons.

Introduction: Recent studies have evaluated patient perception of physician attire; however, few studies have considered physician perceptions of workplace attire. This study aimed to assess current trends regarding attire preferences among surgeons.

Methods: A national, population-based survey was distributed via email and "X" (Twitter).

Primary Team Versus Local Recovery in Liver Transplantation in the Modern Era: A National Analysis of the United Network for Organ Sharing Database.

Background: The implementation of acuity circles (AC) in 2020 and the COVID-19 pandemic increased the use of local surgeons to recover livers for transplant; however, the impact on liver transplant (LT) outcomes is unknown.

Methods: Deceased donor adult LT recipients from the UNOS database were identified.  Recipients were grouped by donor surgeon: local versus primary recovery.

Pectoralis Muscle Index as Predictor of Outcomes in Patients With Severe Blunt Chest Wall Injury.

Introduction: Sarcopenia has been shown to portend worse outcomes in injured patients; however, little is known about the impact of thoracic muscle wasting on outcomes of patients with chest wall injury. We hypothesized that reduced pectoralis muscle mass is associated with poor outcomes in patients with severe blunt chest wall injury.

Methods: All patients admitted to the intensive care unit between 2014 and 2019 with blunt chest wall injury requiring mechanical ventilation were retrospectively identified.

Whole blood storage duration alters fibrinogen levels and thrombin formation.

Introduction: Whole blood resuscitation for hemorrhagic shock in trauma represents an opportunity to correct coagulopathy in trauma while also supplying red blood cells. The production of microvesicles in stored whole blood and their effect on its hemostatic parameters have not been described in previous literature. We hypothesized that microvesicles in aged stored whole blood are procoagulant and increase thrombin production via phosphatidylserine.
