Traumatic brain injury (TBI) causes a profound inflammatory response within the central nervous system and peripheral immune system, which contributes to secondary brain injury and further morbidity and mortality. Preclinical investigations have demonstrated that treatments that downregulate microglia activation and polarize them toward a reparative/anti-inflammatory phenotype have improved outcomes in preclinical models. However, no therapy to date has translated into proven benefits in human patients.

Earlier management of the alveolar defect (primary ABG) would be ideal, but is limited by the minimal bony donor sites available in the infant. In this study we used a critical-size alveolar bone defect model in the rat to investigate the use of Wharton's Jelly (WJ), the stem cell-rich connective tissue matrix of the umbilical cord, to generate bone within the alveolar cleft.

The aim of this study is to examine the feasibility for use of the REBOA device for pediatric IVC injuries and create a potential framework for implementation.
Materials And Methods: A simulated venous system was designed with modeled IVC components based on 290 abdominal computed tomography scans of pediatric trauma patients.
The use of the resuscitative endovascular balloon occlusion of the aorta (REBOA) device is expanding in adult trauma. Reports of its use in pediatric patients have been published, but no guidelines currently exist nor has it been Food and Drug Administration approved in pediatrics. This project develops a model to determine appropriate balloon inflation volumes in pediatric patients to guide potential use.

Methods: Review of a tertiary children's academic hospital's trauma database for VTE events and associated risk factors from 2005 to 2016.
