NFL blood levels are moderated by subconcussive impacts in a cohort of college football players.
Repetitive subconcussive head impacts in contact/collision sports such as in US football are believed to contribute to long-term brain changes and chronic symptoms. However, the lack of tools to measure the effects of repeated subconcussion limits our understanding of potential contributions to neuropathological alterations including cellular damage. ⋯ Acute changes in NFL may be a clinically useful peripheral marker in tracking acute brain damage in collegiate football players, and other contact sports.

Assessing aggression following Acquired Brain Injury (ABI): a systematic review of assessment measures.
Objective: To conduct a systematic review to identify and examine the reliability and validity of standardized measures used to assess aggression in people with ABI. Data sources: Systematic searches of PsychInfo, Medline, Embase, PubMed and CINAHL databases along with hand searching of gray literature and review articles. Study selection: Studies were included if the sample had an ABI, and the measure included assessment of aggression. ⋯ Four measures (MBPC-1990R, NFI, SASNOS and KSMS) demonstrated positive evidence of at least one psychometric property with good quality evidence. Conclusions: Although a large number of general measures were available, there are few measures that only assess post-ABI aggression, and many are not well-validated. Future research should assess the psychometric properties of these measures.

Observational StudyTraumatic brain injury in patients screened for blood alcohol concentration based on the mechanism of injury.
We aimed to investigate in-hospital outcomes of traumatic brain injury (TBI) based on blood alcohol concentration (BAC) and mechanism of injury (MOI). ⋯ Screening for BAC among patients with TBI increases substantially regardless of the MOI. The high BAC value in Fall-related TBI needs more attention to set appropriate preventive measures.

Cerebral blood flow in children and adolescents several years after concussion.
The long-term effects of concussion in youth remain poorly understood. The objective of this study was to determine the association between history of concussion and cerebral blood flow (CBF) in youth. ⋯ Youth with a history of concussion demonstrate differences in regional CBF (not global CBF), but without clear clinical expression.

Multicenter Study Comparative Study Observational StudyComparison of the Neurobehavioral Symptom Inventory and the Rivermead Postconcussion Symptoms Questionnaire.
Objective: This study sought to determine the similarity of constructs measured by the Neurobehavioral Symptom Inventory (NSI) and Rivermead Postconcussive Symptoms Questionnaire (RPQ) and the potential for interchangeability of scores from the two scales. Setting: Three acute inpatient rehabilitation hospitals in the USA. Participants: 497 community dwelling persons with traumatic brain injury (TBI) who completed the NSI and the RPQ during the same assessment. ⋯ A crosswalk between the two measures was created by equating scores from the scales based on percentile ranks. Conclusion: Results indicate substantial conceptual and empirical overlap between the NSI and RPQ. The percentile crosswalk developed from this dataset may allow combined analysis of post-concussive symptoms from datasets that include either the NSI or the RPQ.
