Serum Neurofilament Light in American Football Athletes Over the Course of a Season.
Despite being underreported, American football boasts the highest incidence of concussion among all team sports, likely due to exposure to head impacts that vary in number and magnitude over the season. This study compared a biological marker of head trauma in American football athletes with non-contact sport athletes and examined changes over the course of a season. Baseline serum neurofilament light polypeptide (NFL) was measured after 9 weeks of no contact and compared with a non-contact sport. ⋯ Over the course of the season, an increase (effect size [ES] = 1.8; p < 0.001) was observed post-camp relative to baseline (1.52 ± 1.18 pg•mL-1), which remained elevated until conference play, when a second increase was observed (ES = 2.6; p = 0.008) over baseline (4.82 ± 2.64 pg•mL-1). A lack of change in non-starters resulted in substantial differences between starters and non-starters over the course of the season. These data suggest that a season of collegiate American football is associated with elevations in serum NFL, which is indicative of axonal injury, as a result of head impacts.

Randomized Controlled Trial Multicenter Study
Plasma Potassium Concentration on Admission Correlates with Neurological Outcome in Traumatic Brain Injury Patients Treated with Targeted Temperature Management: a Post Hoc Analyses of a Multicenter Randomized Controlled Trial.
Recent studies have focused on the association between plasma electrolytes, particularly potassium level and neurologic outcomes in patients with traumatic brain injury (TBI). We hypothesized that potassium level on admission is an indicator for initiation of targeted temperature management in patients with severe TBI. ⋯ The initial potassium level may be an indicator in determining appropriate targeted temperature management for patients with TBI. Fever control may be considered instead of MTH for normokalemia patients with TBI on admission.

Assessing bicycle-related trauma using the biomarker S100B reveals a correlation with total injury severity.
Worldwide, the use of bicycles, for both recreation and commuting, is increasing. S100B, a suggested protein biomarker for cerebral injury, has been shown to correlate to extracranial injury as well. Using serum levels of S100B, we aimed to investigate how S100B could be used when assessing injuries in patients suffering from bicycle trauma injury. As a secondary aim, we investigated how hospital length of stay and injury severity score (ISS) were correlated to S100B levels. ⋯ S100B levels were independently correlated with intracranial pathology, but also with the extent of extracranial injury. Length of stay and ISS were both correlated with the admission levels of S100B in bicycle trauma, suggesting S100B to be a good marker of aggregated injury severity. Further studies are warranted to confirm our findings.
