Validating the Brain Injury Guidelines in a Pediatric Population with Mild Traumatic Brain Injury and Intracranial Injury at a Level I Trauma Center.
Children with mild traumatic brain injury (mTBI) and intracranial injury (ICI) often receive unnecessary imaging and hospital admission, leading to avoidable burdens on patients and health systems. While most of these patients do not develop critical neurological injuries, identifying those at risk would allow for a more optimal determination of the appropriate level of initial emergency care. The Brain Injury Guidelines (BIG) were developed as a triage tool to identify adult patients with mTBI and ICI who can benefit from repeat imaging, hospital admission, or neurosurgical consultation. ⋯ Amongst 471 patients (58.6%) with available 6-month patient outcomes, 98% had a GOS-E ≥5 and no outcome difference between BIG categories was observed. Risk stratification of mild TBI using BIG allowed for reasonable identification of children who subsequently develop ciTBI, suggesting that BIG classification can aid in triage and management of patients who might benefit from neurosurgical consultation, repeat imaging, and potentially transfer to a dedicated trauma center. More severe injury according to BIG was not associated with a worse patient outcome.

Randomized Controlled TrialGoal-Oriented Attentional Self-Regulation Training in Chronic Mild Traumatic Brain Injury is Linked to Microstructural Plasticity in Prefrontal White Matter.
Impaired attention is one of the most common, debilitating, and persistent consequences of traumatic brain injury (TBI), which impacts overall cognitive and executive functions in these patients. Previous neuroimaging studies, trying to understand the neural mechanism underlying attention impairment post TBI, have highlighted the role of prefrontal white matter tracts in attentional functioning in mild TBI (mTBI). Goal-Oriented Attentional Self-Regulation (GOALS) is a cognitive rehabilitation training program that targets executive control functions in participants by applying mindfulness-based attention regulation and goal management strategies. ⋯ Our results show significantly better white matter microstructural integrity in left and right anterior corona radiata (ACR) in the GOALS group compared with the control group post-training. Moreover, we found a significant correlation between sustained attention ability of GOALS training participants and white matter integrity of their right ACR pre- and post-training. Finally, our findings indicated that the improved white matter integrity of the ACR in GOALS training participants was the result of increased neurite density and decreased fiber orientation dispersion within this tract.

Supra-Prophylactic Doses of Enoxaparin Reduces Fibrin Deposition Without Exacerbation of Intracerebral Hemorrhage in a Rat Model of Penetrating Traumatic Brain Injury.
Deep vein thrombosis and pulmonary embolism prophylaxis is an important part of trauma care. Despite an increased risk of thrombotic complications, the use of venous thrombosis chemoprophylaxis in penetrating traumatic brain injury (pTBI) patients is met with reluctance from neurosurgeons because of concern for the exacerbation of intracerebral hemorrhage. The objective of this study was to provide initial pre-clinical evidence of the effects of Lovenox (LVX) administration following pTBI with significant intracerebral hemorrhage. ⋯ However, LVX elicited a significant reduction in fibrin deposition in the ipsilateral striatum and lesion site at 7 days post-injury (p < 0.05). Serum levels of beta-amyloid were decreased at 7 days following LVX treatment (p < 0.05) which may indicate neuroprotective effects but was not correlated to brain levels. The results presented indicate that administration of LVX at a dose capable of inducing anticoagulation is safe in a rodent model of pTBI without exacerbation of intracerebral hemorrhage within the first 7 days of injury.

Randomized Controlled TrialAcupuncture Treatment for Chronic Post-traumatic Headache in Individuals with Mild Traumatic Brain Injury: A Pilot Study.
Chronic post-traumatic headache (CPTH) after a mild traumatic brain injury (mTBI) has been reported in up to 60% of patients and can be extremely debilitating. While pharmacological treatments are typically used for CPTH, they frequently cause side effects and have limited effectiveness, leading individuals with CPTH to be unsatisfied with current treatment options and to seek nonpharmacological options. Acupuncture has been identified as a potential treatment option; however, the evidence in this population remains limited. ⋯ There were no significant changes in acute medication use or sleep quality. While there were some QOL improvements identified, these results should be interpreted with caution. Overall, acupuncture was shown to be safe and well-tolerated in people with CPTH after mTBI, and five acupuncture treatments using a standardized protocol shows promise in providing headache relief for this population.
