Multicenter StudyPredicting Psychological Distress after Pediatric Concussion.
A significant proportion of children and adolescents report psychological distress following concussion, but little is known about the predictors of these problems. The purpose of this study was to examine predictive factors of psychological distress following pediatric concussion. It was hypothesized that the presence of pre-injury psychological distress would be the strongest predictor of psychological distress post-concussion, with other demographic and acute injury factors adding incrementally to prediction. ⋯ A pre-injury diagnosis of anxiety and acutely forgetting recent information were significant predictors of psychological distress at 4 weeks, whereas worse acute orientation assessment in the ED predicted psychological distress at 12 weeks. Nearly one of four youth experienced psychological distress after concussion. Clinicians in acute care settings should screen for the factors (pre-injury anxiety, acute mental status) associated with post-injury psychological distress and consider proactively referring patients for further assistance.

Randomized Controlled Trial Multicenter StudyDetermining if Cerebrospinal Fluid Prevents Recurrence of Chronic Subdural Hematoma: A Multi-Center Prospective Randomized Clinical Trial.
Over the decades, the problem of postoperative recurrence of chronic subdural hematoma (CSDH) has not been resolved. The objective of our study was to investigate whether the recurrence rate of CSDH is decreased when artificial cerebrospinal fluid (ACF) is used as irrigation solution for CSDH surgery. The present study was a multi-center, prospective, randomized, open parallel group comparison test of patients enrolled from 10 hospitals in Japan. ⋯ No serious adverse effects related to irrigation fluid were seen in either group. Regarding the irrigation fluid for CSDH surgery, no differences in recurrence rate or time to recurrence were seen between the ACF and NS groups. However, ACF offers sufficient safety as irrigation fluid for CSDH.

Multicenter StudyTesting a Multivariate Proteomic Panel for Traumatic Brain Injury Biomarker Discovery: A TRACK-TBI Pilot Study.
The complex and heterogeneous nature of traumatic brain injury (TBI) has rendered the identification of diagnostic and prognostic biomarkers elusive. A single acute biomarker may not be sufficient to categorize injury severity and/or predict outcome. Using multivariate dimension reduction analyses, we tested the sensitivity and specificity of a multi-analyte panel of proteins as an ensemble biomarker for TBI. ⋯ Inflammatory signatures were significantly increased in patients with positive CT findings, as well as in those who showed poor or incomplete recovery. Inflammation biomarker scores also showed significant sensitivity and specificity as a discriminator of these outcome measures (all areas under the curve [AUCs] >0.62). This proof of concept for the feasibility of multivariate biomarker identification demonstrates the prognostic validity of using a proteomic panel as a potential biomarker for TBI.

Multicenter StudyElectrophysiological multimodal assessments improve outcome prediction in traumatic cervical spinal cord injury.
Outcome prediction after spinal cord injury (SCI) is essential for early counseling and orientation of the rehabilitative intervention. Moreover, prognostication of outcome is crucial to achieving meaningful stratification when conceiving clinical trials. Neurophysiological examinations are commonly employed for prognostication after SCI, but whether neurophysiology could improve the functional prognosis based on clinical predictors remains an open question. ⋯ Adding neurophysiological variables to the model, the AUC increased significantly: 0.956 (95% CI: 0.930-0.982; p = 0.019). More patients could be correctly classified by adding the electrophysiological data. Our study demonstrates that neurophysiological assessment improves the prediction of functional prognosis after traumatic cervical SCI, and suggests the use of neurophysiology to optimize patient information, rehabilitation, and discharge planning and the design of future clinical trials.

Multicenter Study Observational StudyPrediction of Persistent Post-Concussion Symptoms after Mild Traumatic Brain Injury.
Persistent post-concussion symptoms (PPCS) occur frequently after mild traumatic brain injury (mTBI). The identification of patients at risk for poor outcome remains challenging because valid prediction models are missing. The objectives of the current study were to assess the quality and clinical value of prediction models for PPCS and to develop a new model based on the synthesis of existing models and addition of complaints at the emergency department (ED). ⋯ Existing prediction models for PPCS perform poorly. A new model performs reasonably with predictive factors already discernible at ED warranting further external validation. Prediction research in mTBI should be improved by standardizing definitions and data collection and by using sound methodology.
