Randomized Controlled Trial
"Cisternostomy Vs Decompressive Craniectomy for The Management of Traumatic Brain Injury: A Randomized Controlled Trial".
The goal of treatment of traumatic brain injury (TBI) is to avoid secondary brain injury. Decompressive craniectomy has been shown to reduce intracranial pressure (ICP), but it actually provides an outlet for brain tissue to expand without reducing edema. Basal cisternostomy is an emerging microsurgical technique to manage cerebral edema in TBI. Cerebrospinal fluid is released from basal cisterns, which reduces cerebral edema. We compared outcomes of cisternostomy with decompressive craniectomy in a randomized controlled trial and studied the effectiveness of cisternostomy in decreasing cerebral edema. ⋯ Cisternostomy was effective in reducing ICP in patients with TBI. Good Glasgow Outcome Scale scores and low rates of complications were found in the postoperative period after cisternostomy. Age, presenting Glasgow Coma Scale score, Marshall score, other major injuries, and time from trauma to surgery had a significant prognostic impact on outcome in management of TBI.

Correlation of Cerebral and Subcutaneous Glycerol in Severe Traumatic Brain Injury and Association with Tissue Damage.
This study is a substudy of a prospective consecutive double-blinded randomized study on the effect of prostacyclin in severe traumatic brain injury (sTBI). The aims of the present study were to investigate whether there was a correlation between brain and subcutaneous glycerol levels and whether the ratio of interstitial glycerol in the brain and subcutaneous tissue (glycerolbrain/sc) was associated with tissue damage in the brain, measured by using the Rotterdam score, S-100B, neuron-specific enolase (NSE), the Injury Severity Score (ISS), the Acute Physiology and Chronic Health Evaluation Score (APACHE II), and trauma type. A potential association with clinical outcome was explored. ⋯ We have shown that peripheral glycerol may flux into the brain. This effect is associated with worse brain tissue damage. This flux complicates the interpretation of brain interstitial glycerol levels. We remind the clinicians that a damaged blood-brain barrier, as seen in sTBI, may alter the concentrations of various substances, including glycerol in the brain. Awareness of this is important in the interpretation of the data bedside as well in research.

Intermittent fasting enhances hippocampal NPY expression to promote neurogenesis after traumatic brain injury.
Interventions for preventing cognitive dysfunction after traumatic brain injury (TBI) are limited. Given that adult hippocampal neurogenesis after brain injury contributes to cognitive recovery, and hippocampal neurogenesis is potentially affected by nutritional factors, the aim of this study was to examine whether fasting could promote hippocampal neurogenesis and thus ameliorate the cognitive defects after TBI. ⋯ These findings suggest that IF promotes hippocampal neurogenesis after TBI by a mechanism that involves enhancement of NPY expression, to alleviate cognitive dysfunction caused by injury.

Randomized Controlled TrialCervicovestibular Rehabilitation in Adults with Mild Traumatic Brain Injury: A Randomised Clinical Trial.
The objective of this study was to compare the effects of a cervicovestibular rehabilitation program combined with symptom-limited aerobic exercise (SLAE) program to a SLAE program alone in adults with persistent symptoms after mild traumatic brain injury (mTBI) on severity of symptoms and other indicators of clinical recovery. In this single-blind, parallel-group randomized controlled trial, 60 adults with persistent symptoms after mTBI were randomly assigned to: (1) a 6-week SLAE program or (2) a 6-week cervicovestibular rehabilitation program combined with a SLAE program. All participants took part in four evaluation sessions (baseline, week 6, 12, and 26) performed by a blinded evaluator. ⋯ For PCSS, NPRS, NDI, HDI, DHI, and return to function, there were no group-by-time interactions at any time points follow-up (p > 0.05); clinically significant time effects were, however, observed (p < 0.05). There were group-by-time interactions at weeks 6 and 12 for vestibulo-ocular reflex (p < 0.003) and the craniovertebral mobility (p < 0.001) measures in favor of the cervicovestibular rehabilitation group. The study indicates that a cervicovestibular rehabilitation program combined with SLAE was not superior to a SLAE program alone in term of symptoms and functional level improvement but resulted in improved physical cervical and vestibular function.

Randomized Controlled TrialBrain Injury Effects on Neuronal Activation and Synaptic Transmission in the Basolateral Amygdala (BLA) of Adult Male and Female Wistar Rats.
Traumatic brain injury (TBI) is defined as brain damage produced by an external mechanical force that leads to behavioral, cognitive, and psychiatric sequelae. The basolateral amygdala (BLA) is involved in emotional regulation, and its function and morphology are altered following TBI. Little is known about potential sex-specific effects of TBI on BLA neuronal function, but it is critical for the field to identify potential sex differences in TBI effects on brain and behavior. ⋯ Further, TBI increased spontaneous excitatory and inhibitory postsynaptic current (sEPSC and sIPSC) amplitude in BLA neurons of females relative to all other groups. TBI increased sEPSC frequency in BLA neurons of females relative to males but did not alter sIPSC frequency. In summary, lateral fluid percussion produced different physiological responses in male and female rats, as well as sex-specific alterations in BLA neuronal activation, excitability, and synaptic transmission 1 h after injury.
