Progression of hemorrhagic injury (PHI) in children with traumatic brain injury portends poor outcomes. The association between thromboelastography (TEG), functional coagulation assays, and PHI is not well characterized in children. ⋯ Although INR was elevated in children with PHI and has been associated with poor clinical outcomes, only admission TEG-ACT was independently associated with PHI. Further study is warranted to determine whether TEG-ACT reflects an actionable therapeutic target.

Brain injury following head trauma occurs in 2 stages, namely an early stage attributable to mechanical damage and a delayed stage resulting primarily from neuroinflammation. In this study, we examined early proinflammatory cytokine upregulation in an animal model of traumatic brain injury (TBI) and examined the effects of early anti-inflammatory therapy on neuroinflammation, neuropathology, and systemic inflammatory activity. ⋯ The administration of anti-inflammatory drugs or vitamin D analogs in the early period following TBI might help to reduce secondary injury from neuroinflammation.

Altered levels of cerebrospinal fluid (CSF) glucose and lactate concentrations are associated with poor outcomes in acute brain injury patients. However, no data on changes in such metabolites consequently to therapeutic interventions are available. The aim of the study was to assess CSF glucose-to-lactate ratio (CGLR) changes related to therapies aimed at reducing intracranial pressure (ICP). ⋯ In this study, CGLR significantly changed over time, regardless of the study group. However, these effects were more significant in those patients receiving interventions to reduce ICP.

During deployment of military medical teams similarly to prehospital practice, without immediate computed tomography scan access, identifying patients requiring neuro-specific care to manage pragmatic triage proves crucial. We assessed the contribution of this portable near-infrared spectroscope (NIRS) handheld device, Infrascanner Model 2000 (InfraScan Inc.; Philadelphia, PA), to screen patients suspected to require specific neurosurgical care. ⋯ The NIRS was relevant to detect hematoma leading to prompt surgery in our study. The lack of specificity in a nonselected cohort of patients underlines the need to associate simple clinical feature such as neurological deficit and NIRS results to perform rational triage.
