Unihemispheric head gunshot wound (HGSW) are associated with improved survival; however, specific clinical and radiographic characteristics associated with survival have not been clearly defined. To further guide prognosis estimates and care discussions, this study aims to identify unihemispheric HGSWs injury patterns; comparing them to bihemispheric HGSWs characterizing factors associated with improved clinical outcomes and survival. ⋯ We found presenting clinical features and CT imaging patterns previously associated with improved survival in HGSW patients is similar in unihemispheric specific injuries. Importantly, a more favorable admission GCS score may portend survivability in unihemsipheric HGSW. Furthermore, unihemispheric HGSW survivors may have improved clinical outcomes, length of stay and disposition location.

Combined traumatic brain injury and hemorrhagic shock in ferrets leads to structural, neurochemical, and functional impairments.
Aeromedical evacuation-relevant hypobaria after traumatic brain injury (TBI) leads to increased neurological injury and death in rats relative to those maintained under normobaria. Applicability of rodent brain injury research to humans may be limited, however, by differences in neuroanatomy. Therefore, we developed a model in which ferrets are exposed to polytrauma consisting of controlled cortical impact TBI and hemorrhagic shock subjected 24 h later to 6 h of hypobaria or normobaria. ⋯ Finally, cortical lesion volume was not exacerbated by hypobaria exposure on day 7 post-injury. Results suggest that air travel 24 h after polytrauma is associated with structural changes in the ferret brain. Future studies should investigate secondary injury from hypobaria after polytrauma in greater detail including alternative outcome measures, time points, and exposure to multiple flights.

Patients with traumatic brain injury associated with intracranial hemorrhage are commonly admitted to the intensive care unit (ICU); however, the need for ICU care for patients with isolated traumatic subarachnoid hemorrhage (tSAH) remains unclear. We aimed to investigate the association between the ICU admission practices and outcomes in patients with isolated tSAH. ⋯ There was no significant association between the ICU admission practices and outcomes in patients with isolated tSAH, whereas higher ICU admission rates were associated with significantly higher hospitalization costs. Our results provide an opportunity for improved health care allocation in the management of patients with isolated tSAH.

Is C-reactive protein-albumin ratio or neutrophil-lymphocyte ratio a better indicator to predict in-hospital mortality in traumatic brain injury?
Neutrophil-lymphocyte ratio (NLR) and C-reactive protein-albumin ratio (CAR) are simple and objective markers of inflammatory responses. However, there are no studies in the literature evaluating these two markers together in traumatic brain injury (TBI). Therefore, this study aimed to examine whether CAR or NLR is a better biomarker for predicting in-hospital mortality in patients with TBI. ⋯ The results of this study showed that CAR has better prognostic value than NLR in predicting in-hospital mortality in patients with TBI.
