Traumatic brain injury (TBI) and hemorrhage remain challenging to treat in austere conditions. Developing a therapeutic to mitigate the associated pathophysiology is critical to meet this treatment gap, especially as these injuries and associated high mortality are possibly preventable. Here, Thera-101 (T-101) was evaluated as low-volume resuscitative fluid in a rat model of TBI and hemorrhage. The therapeutic, T-101, is uniquely situated as a TBI and hemorrhage intervention. It contains a cocktail of proteins and microvesicles from the secretome of adipose-derived mesenchymal stromal cells that can act on repair and regenerative mechanisms associated with poly-trauma. T-101 efficacy was determined at 4, 24, 48, and 72 h post-injury by evaluating blood chemistry, inflammatory chemo/cytokines, histology, and diffusion tensor imaging. Blood chemistry indicated that T-101 reduced the markers of liver damage to Sham levels while the levels remained elevated with the control (saline) resuscitative fluid. Histology supports the potential protective effects of T-101 on the kidneys. Diffusion tensor imaging showed that the injury caused the most damage to the corpus callosum and the fimbria. Immunohistochemistry suggests that T-101 may mitigate astrocyte activation at 72 h. Together, these data suggest that T-101 may serve as a potential field deployable low-volume resuscitation therapeutic.

White blood cell (WBC) subtypes reflect immune and inflammatory conditions in patients. This study aimed to examine the association between the ratio of platelets to WBC subtypes and mortality outcomes in patients with moderate-to-severe traumatic brain injury (TBI). The Trauma Registry System of the hospital was retrospectively reviewed to gather medical records of 2397 adult patients who were hospitalized from 2009 to 2020 and had moderate-to-severe TBI with a head abbreviated injury scale (AIS) score of 3 or higher.

Background/aim: Circadian rhythm proteins (CRPs) play critical roles in both physiological and pathophysiological conditions, including neurodegenerative disorders. As members of CRPs, the nuclear receptors Rev-Erbα/β regulate circadian rhythm particularly by inhibiting Bmal1 protein and are involved in the neuroinflammation and cell death processes. However, their roles in the development of neuronal injury after traumatic brain injury (TBI) were largely unexplored, and so were investigated in the present study.

Introduction: This study aims to evaluate clinical outcomes in geriatric trauma patients with isolated chest or abdominal injuries with or without traumatic brain injury (TBI) receiving whole blood (WB), component (COMP), or WB and component therapy (WB + COMP).
Methods: This retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program Participant Use File dataset from 2017 to 2021 evaluated geriatric (age ≥65) trauma patients with moderate-to-severe isolated chest (abbreviated injury scale (AIS) chest ≥2) or abdominal (AIS abdomen ≥2) injuries with or without TBI (AIS head ≥2) receiving WB, COMP, or WB + COMP. Outcomes included emergency department and 24-h mortality, blood product volume (mL) at 4 hs, and intensive care unit-length of stay.

Background: Hemorrhage and traumatic brain injury (TBI) are the leading causes of death in trauma. Future military conflicts are likely to be in austere environments, where prolonged damage-control resuscitation (p-DCR) may be required for 72 hours before evacuation. Previous studies showed that early administration of fresh frozen plasma (FFP) during p-DCR can significantly decrease the volume of resuscitation required in models of hemorrhagic shock and also provide neuroprotection after TBI.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and a major global health concern. In the United States (US), individuals of Black or African American racial identity experience disproportionately higher rates of TBI and suffer from worse post-injury outcomes. Contemporary research agendas have largely overlooked or excluded Black populations, resulting in the continued marginalization of Black patient populations in TBI studies, thereby limiting the generalizability of ongoing research to patients in the US and around the world.
