Randomized Controlled TrialRandomized evaluation of CDC HEADS UP concussion education materials for youth sport coaches.
The Centers for Disease Control and Prevention (CDC) HEADS UP youth sports coach materials are the most widely adopted form of concussion education for coaches across the United States-reaching millions of youth sports coaches over the last decade. These materials focus on concussion symptom identification, response, and management (e.g., return to school and sports), while also addressing the importance of communicating to athletes and their families about concussion safety. The purpose of this study was to assess the effectiveness of CDC HEADS UP materials on coach knowledge and communication with youth athletes about concussion safety. ⋯ Concussion symptom knowledge and communication intentions also significantly increased in the intervention group but not in the control group. This study provides evidence that CDC HEADS UP materials increase the likelihood that youth sport coaches communicate with their athletes about concussion safety. As youth sports organizations increasingly mandate concussion education for coaches, CDC HEADS UP materials may be considered a leading resource for adoption and setting-relevant implementation.

Multicenter StudyMachine Learning to Predict Three Types of Outcomes After Traumatic Brain Injury Using Data at Admission: A Multicenter Study for Development and Validation.
The difficulty of accurately identifying patients who would benefit from promising treatments makes it challenging to prove the efficacy of novel treatments for traumatic brain injury (TBI). Although machine learning is being increasingly applied to this task, existing binary outcome prediction models are insufficient for the effective stratification of TBI patients. The aim of this study was to develop an accurate 3-class outcome prediction model to enable appropriate patient stratification. ⋯ As a result, it is expected to be more impactful in the development of appropriate patient stratification methods in future TBI studies than conventional binary prognostic models. Further, outcomes were predicted based on only clinical data obtained from the emergency department. However, developing a robust model with consistent performance in diverse scenarios remains challenging, and further efforts are needed to improve generalization performance.

To identify the distributions of and extent of variability among 3 new sets of postdischarge quality-metrics measured within 30/90/365 days designed to better account for the unique health needs of older trauma patients: mortality (expansion of the current in-hospital standard), readmission (marker of health-system performance and care coordination), and patients' average number of healthy days at home (marker of patient functional status). ⋯ The use of new postdischarge quality-metrics provides a more complete picture of older adult trauma care: 1 with greater room for improvement and better reflection of multiple aspects of quality important to the health and recovery of older trauma patients when compared with reliance on quality benchmarking based on in-hospital mortality alone.

Associations of Microvascular Injury-Related Biomarkers with Traumatic Brain Injury Severity and Outcomes: A TRACK-TBI Pilot Study.
Traumatic brain injury (TBI) is characterized by heterogeneity in terms of injury severity, mechanism, outcome, and pathophysiology. A single biomarker alone is unlikely to capture the heterogeneity of even one injury subtype, necessitating the use of panels of biomarkers. Herein, we focus on traumatic cerebrovascular injury and investigate associations of a panel of 16 vascular injury-related biomarkers with indices of TBI severity and outcomes using data from 159 participants in the Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) Pilot Study. ⋯ In principal components analysis, principal component (PC)1, comprised of Ang1, bFGF, P-selectin, VEGF-C, VEGF-A, and Tie2, was associated with less severe injury (age-adjusted odds ratio [OR]: 0.63, 95% confidence interval [CI]: 0.44-0.88 for head computer tomography [CT] positive vs. negative) and PC2 (Ang-2, E-selectin, Flt-1, placental growth factor, thrombomodulin, and vascular cell adhesion protein 1) was associated with greater injury severity (age-adjusted OR: 2.29, 95% CI: 1.49-3.69 for Glasgow Coma Scale [GCS] 3-12 vs. 13-15 and age-adjusted OR 1.59, 95% CI: 1.11-2.32 for head CT positive vs. negative). Neither individual biomarkers nor PCs were associated with outcomes in adjusted models (all p > 0.05). In conclusion, in this trauma-center based population of acute TBI patients, biomarkers of microvascular injury were associated with TBI severity.

To date, the research on the prognosis of the neuropsychological function of patients with post-traumatic seizure (PTE) is sparse. This study aimed to systematically map the literature's extent, range, and characteristics regarding PTE and neuropsychological impairments. ⋯ The results of this review suggest that patients with PTE may have neuropsychological function impairments. More attention needs to be paid to older patients and those with higher brain injury and seizure severity. Additional investigation is necessary to determine the clinical characteristics of TBI and PTE and elucidate the relations between PTE and specific neuropsychological domains.
