To determine the feasibility, efficacy, and safety of cold stored compared to room temperature platelet transfusion in patients with traumatic brain injury. ⋯ In brain injured patients requiring platelet transfusion, early cold stored platelet transfusion is feasible, and did not result in improved 6-month Glasgow Coma Scale-Extended scores. Early cold stored platelet transfusion was associated with a lower rate of neurosurgical operative intervention without an increase in adverse events. The storage age of the cold stored platelet product was not associated with outcome differences. Future phase 3 clinical trials are required to determine clinical outcome differences and safety attributable to cold stored platelet transfusion following traumatic brain injury.

Venous thromboembolism (VTE) remains a major source of morbidity and mortality in severely injured patients despite current methods of risk stratification and prophylaxis, suggesting incomplete understanding of VTE risk factors. Given the liver's role in coagulation, we hypothesized that liver injury (LI) is associated with increased rates of VTE in severely injured patients. ⋯ In severely injured patients, LI is an independent predictor of PE, but not DVT, suggesting LI is the source of either emboli or a more complex locally prothrombotic focus leading to downstream thrombi in the lung without causing upstream systemic venous thrombi. Further work should focus on elucidation of mechanisms including the portal venous blood coagulation profile, endothelial injury in the liver, and the potential for stasis of venous blood traversing an injured liver as well as the role for including LI in VTE risk stratification.

Point-of-care ultrasound (POCUS) can potentially be used in the triage of patients with elbow injuries. However, the diagnostic accuracy of POCUS performed by non-radiologists for the exclusion of elbow fractures is yet unknown. This study aimed to investigate the diagnostic potential of POCUS of the posterior fatpad performed by non-radiologists in the workup of adult patients presenting with elbow injuries. ⋯ POCUS of the posterior fatpad is a promising adjunct to physical examination to determine the need for further diagnostic studies in the triage of patients with elbow injuries. Sensitivity after a limited training is high, but not perfect, and can likely further be improved with additional training.
