This observational study examined 287 TBI patients (251 moderate, 36 severe) across two hospitals to evaluate how BMI changes during hospitalization affect functional recovery measured by Glasgow Outcome Scale-Extended (GOSE). Results showed differing BMI patterns between moderate and severe TBI groups, with significant associations identified between BMI changes and patient outcomes at discharge.
This systematic review examined how climate and environmental conditions affect concussion rates in outdoor contact sports by analyzing 20 studies from major medical databases. The evidence indicates no significant difference in concussion risk based on playing surface type (grass vs. artificial) or game location (home vs. away), though findings on altitude and temperature effects remain inconclusive.
A cross-sectional study of 315 medical students in Saudi Arabia found that 68.3% demonstrated good knowledge about concussions as mild traumatic brain injuries, with 80.3% correctly recognizing the need to report symptoms to healthcare providers. However, misconceptions persisted, including the belief that all concussion patients require seven days of complete rest, highlighting gaps in clinical training despite overall adequate foundational understanding.
A study of over 3,000 athletes examined whether pre-season visual attention testing could identify those at risk for clinically significant concussions. Both traditional and penalized regression models found that prior head injury history and visual attention deficits were associated with worse concussion outcomes.
This consensus study used modified Delphi methodology with UK Head Injury Network specialists to establish evidence-based standards for concussion care structure and processes in England. Final consensus produced 18 statements covering care pathways, prognosis assessment, recovery measures, and outpatient clinic provision to improve healthcare quality and patient outcomes.
