Active clinical trials for "Brain Injuries"

Severe traumatic brain injury is associated with life-threatening and incapacitating secondary injury. Contemporary therapeutic interventions are aimed at preventing and treating secondary damage. In this context, improved cerebral metabolism is an important target in modern neurointensive care. The main hypothesis is that continuous intravenous infusion of glutamyl-alanyl dipeptide restores disturbed brain metabolism following severe traumatic brain injury.

This study compares the effects of Individualized Scheduled Telephone Support (ISTS) and Usual Care (UC) for service members with Mild Traumatic Brain Injury (mTBI). A total of 400 service members will participate in this study. ISTS is a telephone intervention that provides injury-related education, training in problem solving, and focused behavioral strategies for problems (e.g. anxiety, depression) that commonly co-occur with MTBI. ISTS also includes access to usual care and web-based and printed educational material. The 12 phone calls included in ISTS will be administered over a 6-month period. UC is the usual care provided to service members attending the Traumatic Brain Injury (TBI) Clinics at Madigan Army Medical Center and Womack Army Medical Center, plus web-based education and 12 mailings of educational materials over a 6-month period. Subjects will complete major assessments at study entry and then 6 months and 12 months later. The primary aim of the study is to compare the effects of ISTS and UC on post-concussive symptoms and emotional distress at the 6-month assessment. The investigators predict that participants who receive ISTS will report lower levels of post-concussive symptoms and emotional distress at the 6-month assessment. Secondary aims include comparing the longer term effects of ISTS and UC at the 12-month assessment, as well as comparing their effects on other outcomes such as post-traumatic stress symptoms, quality of life, resilience, and work activity.

The aim of this study is to determine whether passive gait training increases arousal, demonstrated as changes in EEG (electroencephalogram) activity. Hypotheses: 1) Passive gait training increases EEG-frequency in patients with impaired consciousness due to severe traumatic brain injury. 2) Passive gait training increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe traumatic brain injury.

The purpose of this study is to determine whether rosuvastatin could alter the immunological response after head injury by modulating TNF-alpha,IL6,IL-1.

The purpose of this study is to determine if hyperbaric oxygen therapy (HBOT) improves the cognitive function of OIF/OEF individuals who have chronic mild to moderate traumatic brain injury (TBI). Cognitive function includes such things as thinking, remembering, recognition, concentration ability and perception. Traumatic brain injury is common with head injuries caused by blows to the head, nearby explosions, or concussion. Subjects will be assigned to an intervention or sham arm. Computer based cognitive tests will be used as outcome measures. Subjects are enrolled by invitation only.

Neurocritical ill patients are frequently transfused. Red blood cell transfusion (RBCT) in these patients has been associated with deleterious effects, including higher rates of nosocomial infections, multi-organ failure, and mortality. Therefore, it seems crucial to avoid any unnecessary RBCT. Most critically ill patients tolerate hemoglobin levels near 7 g/dL without an increase in morbidity or mortality rates. In this regard, a recent sub-analysis of TRICC trial has showed that TBI patients may tolerate hemoglobin levels as low as 7 g/dL, but other studies including neurocritical patients suggested that severe anemia may worsen clinical outcome. Therefore, optimal hemoglobin levels in neurocritical care patients remain largely unknown. Some textbooks and guidelines recommend to transfuse these patients to reach hemoglobin levels near to 10 g/dL, despite the lack of a solid scientific background supporting this target. Even though it has not been demonstrated, hemoglobin-based RBCT prescription could result in over- or under-transfusion in neurocritical patients. Alternatively, it has been suggested that more physiological transfusion triggers, using direct signals coming from the brain, will progressively replace arbitrary hemoglobin-based transfusion triggers in the neurocritical patients [65]. At the neurocritical units, patients are often monitored by using non-invasive methods, such as near infrared spectroscopy which indirectly measures regional cerebral oxygen saturation (rSO2). Changes in rSO2 values have been shown to directly correlate with changes in erythrocyte mass, thus increasing with RBCT and decreasing with blood losses. Moreover, rSO2 values also show a good correlation with clinical outcome and other variables which are often monitored in TBI patients. The purpose of this study is to ascertain as to whether rSO2 levels are more efficacious than conventional hemoglobin levels in guiding RBCT in patients admitted to a neurocritical care unit.

The purpose of the study is to determine the efficacy of aerobic exercise for improving cognition, mood, and fatigue after Traumatic Brain Injury (TBI) as well as examine the role of Brain Derived Neurotropic Factor (BDNF) and peripheral Vascular Endothelial Growth Factor (VEGF) as mediators of response to exercise.

The purpose of this study is to determine whether NNZ-2566 is safe and effective in the treatment of Traumatic Brain Injury (TBI).

Context: Neurocognitive dysfunction complicates coronary artery bypass graft surgery. Neurocognitive dysfunction is a measurable problem with thinking. Erythropoietin may be a neuroprotectant. Objective: To investigate the feasibility and safety of three doses of human recombinant erythropoietin to reduce neurocognitive dysfunction in coronary artery bypass graft patients.

The purpose of this study is: To determine the safety and feasibility of performing an international multi-centre randomized control trial of early and prolonged hypothermia to improve outcome in children with severe traumatic brain injury (TBI). To determine whether in children with severe traumatic brain injury, prolonged initial hypothermia (minimum 72 hours at 32-33 degrees) improves the proportion of good outcomes 12 months after injury when compared to initial normothermia (36-37 degrees).
