BACKGROUND: Transforming growth factor-beta 1 (TGF-β1) regulates many processes after traumatic brain injury (TBI). Both Neuro AiD(™) (MLC601) and Astragaloside (AST) attenuate microglia activation in rats with TBI. The purpose of this study was to investigate whether MLC601 or AST improves output of TBI by affecting microglial expression of TGF-β1. MATERIALS AND METHODS: Adult male Sprague-Dawley rats (120 in number) were used to investigate the contribution of TGF-β1-containing microglia in the MLC601-mediated or the AST-mediated neuroprotection in the brain trauma condition using lateral fluid-percussion injury...

Photobiomodulation (PBM) describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying. One of the organ systems of the human body that is most necessary to life, and whose optimum functioning is most worried about by humankind in general, is the brain. The brain suffers from many different disorders that can be classified into three broad groupings: traumatic events (stroke, traumatic brain injury, and global ischemia), degenerative diseases (dementia, Alzheimer's and Parkinson's), and psychiatric disorders (depression, anxiety, post traumatic stress disorder)...

OBJECTIVE: To evaluate the extent of persistent neuropsychological impairment in patients with complicated versus uncomplicated mild traumatic brain injury (mTBI). METHODS: 61 patients with mTBI (GCS 13 to 15) were prospectively recruited, categorized according to baseline CT findings, and underwent neuropsychological assessment at initial admission (n=61) as well as at 6 month follow-up (n=30). A paired t-test, Cohen's d effect size calculation, and repeated measure ANOVA were used to establish the differences between the groups in terms of their neuropsychological performance...

Since 2006, several longitudinal studies have assessed environmental or behavioural factors that seem to modify the risk of developing Parkinson's disease. Increased risk of Parkinson's disease has been associated with exposure to pesticides, consumption of dairy products, history of melanoma, and traumatic brain injury, whereas a reduced risk has been reported in association with smoking, caffeine consumption, higher serum urate concentrations, physical activity, and use of ibuprofen and other common medications...

Traumatic brain injury (TBI) is known to have a substantial, though highly variable, impact on cognitive abilities. Due to the wide range of cognitive abilities among healthy individuals, an objective assessment of TBI-related cognitive loss requires an accurate measurement of premorbid cognitive performance. To address this problem, we recruited 50 adults who sustained a TBI and had performed a cognitive baseline assessment in adolescence as part of the aptitude tests mandated by the Israeli Defense Forces...

Lipid peroxidation is a key contributor to the pathophysiology of traumatic brain injury (TBI). Traditional antioxidant therapies are intended to scavenge the free radicals responsible for either the initiation or the propagation of lipid peroxidation (LP). A more recently explored approach involves scavenging the terminal LP breakdown products that are highly reactive and neurotoxic carbonyl compounds 4-hydroxynonenal (4-HNE) and acrolein to prevent their covalent modification and rendering of cellular proteins non-functional leading to loss of ionic homeostasis, mitochondrial failure, and subsequent neuronal death...

Dear Editor I read with great interest the manuscript titled "A New Panel of Blood Biomarkers for the Diagnosis of Mild Traumatic Brain Injury/Concussion in Adults" by Shan R, et al, published in the January issue of the Journal. (1) I do have some questions. The key to marker discovery studies is a precise and accurate description of how the population was identified, including controls. I have significant concerns about the control population in the manuscript. In the presentation the characteristics of the control group are unclear, described only as "not patients in the ED" and with the same exclusion criteria of the other cohorts...

INTRODUCTION: Behavioral changes often occur after moderate-to-severe traumatic brain injury (TBI) and can lead to poor health, psychosocial functioning, and quality of life. Challenges in evaluating these behaviors often result from the complexity and variability in the way they are conceptualized and defined. We propose and test a conceptual model that is specific to behavioral symptoms after TBI, to serve as a basis for better assessment and treatment. We hypothesized that clusters of individuals, with unique emotional, cognitive, and behavioral characteristics, would emerge that would illustrate this conceptual model...

Stuttering affects about 1% of the general population and from 8 to 11% of children. The onset of persistent developmental stuttering (PDS) typically occurs between 2 and 4 years of age. The etiology of stuttering is unknown and a unifying hypothesis is lacking as of now. Clues to the pathogenesis of stuttering include the following observations: PDS is associated with adverse perinatal outcomes and birth-associated trauma; stuttering can recur or develop in adulthood following traumatic events such as brain injury and stroke; PDS is associated with structural and functional abnormalities in the brain associated with speech and language; and stuttering resolves spontaneously in a high percentage of affected children...

In military populations, traumatic brain injury (TBI) also holds potential to increase impulsivity and impair mood regulation due to blast injury effects on ventral frontal cortex - to put military personnel at risk for suicide or substance abuse. We assessed a linkage between depression and impaired behavioral inhibition in 117 blast-exposed service members (SM) and veterans with post-concussion syndrome (PCS), where PCS was defined using a Rivermead Postconcussive Symptom Questionnaire (RPQ) modified to clarify whether each symptom worsened compared to pre-blast...

Severe trauma may cause refractory life-threatening respiratory failure requiring extracorporeal membrane oxygenation (ECMO). Concurrent traumatic brain injury, however, complicates the use of ECMO because of the major risk of intracranial bleeding with systemic anticoagulation. Craniotomy and/or craniectomy for hematoma evacuation during ECMO are extremely high-risk procedures secondary to ongoing anticoagulation, and there are only a few such case reports in the literature.We present the case of a child with multiple thoracic injuries and life-threatening respiratory failure supported on ECMO...

PURPOSE OF STUDY: Individualized interdisciplinary care is the hallmark for rehabilitation following traumatic brain injury (TBI). Veterans Health Administration (VHA) utilizes an electronic note template to document Interdisciplinary Rehabilitation and Community Reintegration (IRCR) care plans for Veterans with TBI requiring rehabilitation. All Veterans with a TBI diagnosis, receiving skilled therapy for TBI-related issues, and followed by a case manager must receive a care plan. The purpose of this study was to determine the level of compliance with the IRCR care plan requirements used to identify Veterans with TBI in need of the care plan and to evaluate the reasons for inconsistent compliance...

PURPOSE OF REVIEW: The traumatically injured patient is at high risk for developing venous thromboembolism. Clinical practice guidelines developed by the American College of Chest Physicians and the Eastern Association for the Surgery of Trauma recognize the importance of initiating thromboprophylaxis, but the guidelines lack specific recommendations regarding the timing and dose of pharmacologic thromboprophylaxis. We review the literature regarding initiation of thromboprophylaxis in different injuries, the use of inferior vena cava filters, laboratory monitoring, dosing regimens, and the use of antiplatelet therapy...

HS-1-associated protein X-1 (Hax-1) has been suggested to be expressed in various rodent and human tissues. Accumulating evidence has demonstrated that Hax‑1 exerts an anti‑apoptotic effect in neurological diseases. Furthermore, it has also been reported that Hax‑1 interacts with various apoptosis‑associated proteins, including high temperature-regulated A2 (HtrA2) and caspase‑3. Previous studies have indicated that abnormal expression of Hax‑1 may be associated with the development of the nervous system and with the pathophysiology of neurological diseases, including traumatic brain injury and cerebral ischemia...

PURPOSE OF REVIEW: This article evaluates whether specific drugs are able to facilitate motor recovery after stroke or improve the level of consciousness, cognitive, or behavioral symptoms after traumatic brain injury. RECENT FINDINGS: After stroke, serotonin reuptake inhibitors can enhance restitution of motor functions in depressed as well as in nondepressed patients. Erythropoietin and progesterone administered within hours after moderate to severe traumatic brain injury failed to improve the outcome...
