Clinical Utility of Near-infrared Device in Detecting Traumatic Intracranial Hemorrhage: A Pilot Study Toward Application as an Emergent Diagnostic Modality in a Low Resource Setting.
Limited computed tomography (CT) availability in low- and middle-income countries frequently impedes life-saving neurosurgical decompression for traumatic brain injury. A reliable, accessible, cost-effective solution is necessary to detect and localize bleeds. We report the largest study to date using a near-infrared device (NIRD) to detect traumatic intracranial bleeds. ⋯ For all patients who required craniectomy or craniotomy, the device demonstrated 100% sensitivity. NIRD is highly sensitive, specific, and reproducible over time in diagnosing intracranial bleeds. NIRD may inform neurosurgical decision making in settings where CT scanning is unavailable or impractical.

ReviewNutritional supplement and dietary interventions as a prophylaxis or treatment of sub-concussive repetitive head impact (SRHI) and mild traumatic brain injury (mTBI): A systematic review.
Mild traumatic brain injury (mTBI) affects 42 to 56 million individuals worldwide annually. Even more individuals are affected by sub-concussive repetitive head impacts (SRHIs). Such injuries may result in significant acute and chronic symptoms. ⋯ Strongest evidence supports n-3FA utility for neurotrauma prevention in athletes exposed to SRHI. Both Pinus radiata and melatonin may have benefit for persistent post-concussion symptoms; however, additional multi-center studies are necessary prior to making a definitive conclusion on these supplements' efficacy. Future studies should continue to assess both novel interventions and additional interventions examined in this review to bring additional evidence to the burgeoning field of nutritional and dietary interventions for SRHI and mTBI.

Review Meta AnalysisSensitivity and Specificity of Exercise Intolerance on Graded Exertion Testing for Diagnosing Sport-related Concussion: A Systematic Review and Exploratory Meta-Analysis.
Abstract There is no single gold standard test to diagnose sport-related concussion (SRC). Concussion-related exercise intolerance, that is, inability to exercise to the individual's appropriate level due to exacerbation of concussion-like symptoms, is a frequent finding in athletes early after SRC that has not been systematically evaluated as a diagnostic test of SRC. We performed a systematic review and proportional meta-analysis of studies that evaluated graded exertion testing in athletes after SRC. ⋯ The pooled estimate of incidence of exercise intolerance in participants without SRC equated to an estimated specificity of 94.6% (95% CI: 91.1, 97.3). The results suggest that exercise intolerance measured on systematic testing within 2 weeks of SRC may have excellent sensitivity for helping to rule in the diagnosis of SRC and excellent specificity for helping to rule out SRC. A prospective validation study to determine the sensitivity and specificity of exercise intolerance on graded exertion testing for diagnosing SRC after head injury as the source of symptoms is warranted.
