Filter by:Extremely low birth weight (ELBW), birth weight less than or equal to 1000 g, infants are at high risk for developing brain injury in the first week of life. Intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL) are the most common injuries in this group of infants. Their incidence is inversely proportional to gestational age (GA) and birth weight (BW). These lesions are associated with neurodevelopmental delay, poor cognitive performance, visual and hearing impairment, epilepsy, and cerebral palsy; and instability of systemic hemodynamics during transition from intra- to extra-uterine life and during the early neonatal period is believed to be at their genesis. While the incidence of ultrasound- diagnosed cystic PVL has decreased dramatically over the last 2 decades, diffuse PVL detected by magnetic resonance imaging (MRI) is still prevalent in survivors of neonatal intensive care. Moreover, PVL, even when non-cystic, is associated with decreased cortical complexity and brain volume and eventual neurocognitive impairment. Currently, clinicians lack the tools to detect changes in cerebral perfusion prior to irreversible injury. Unfortunately, the incidence of brain injury in ELBW infants has remained relatively stable. Once translated to the bedside, the goal of this research is to develop a monitoring system that will allow researchers to identify infants most at risk for IVH and PVL and in the future, intervention studies will be initiated to use the changes in cerebral perfusion to direct hemodynamic management. The purpose of this study is to first understand the physiology of brain injury and then to eventually impact the outcomes in this high-risk group of infants by assessing the ability of the diastolic closing margin (DCM), a non-invasive estimate of brain perfusion pressure, to predict hemorrhagic and ischemic brain injury in ELBW infants. The information collected for this study will help develop algorithms or monitoring plans that will maintain the appropriate brain perfusion pressure and thereby, prevent severe brain injury.
Explore the benefit of the game-based virtual reality system in improving lower extremity kinematics and balance in patients suffering from disease/disorders including Diabetes, Cancer, Multiple Sclerosis, Arthritis, Parkinson's disease, Cognitive Disorders, Brain Injury, Stroke or Frailty. A four to six weeks of training with 2 training session/week will be provided.
The purpose of this study is to assess the safety and efficacy of injectable collagen scaffold combined with Mesenchymal stem cells (MSCs) transplantation in patients with brain injury.
This is a prospective investigation of the effects of Laughter therapy (LT) on perceived stress, self-efficacy, mood and other wellness measures in people with the following neurological conditions: Alzheimer's disease, amyotrophic lateral sclerosis, brain injury, Huntington's Disease, multiple sclerosis, Parkinson's Disease, post-stroke, spinal cord injury.
Our central hypothesis is that chronic balance deficits after mild traumatic brain injury (mTBI) result from impairments in central sensorimotor integration (CSMI) that may be helped by rehabilitation. There are two objectives of this proposal; the first objective is to characterize balance deficits in people with mTBI. The second objective is to use a novel auditory bio-feedback (ABF) device to improve measures central sensorimotor integration and balance control.
Adolescents with concussion will be randomly assigned to a treatment group where they will receive sub-threshold exercise, or assigned to a placebo group where they will receive structured stretching exercises. Both groups will receive standard medical coverage with regular clinic visits. All participants will record symptoms daily on a dedicated web site. All participants will be evaluated at time 1 with (1) structured physical exam, and (2) structured exercise stress test which is terminated when there is symptom exacerbation. The primary outcome measure is time to recovery where recovery is defined as (1) asymptomatic for two consecutive days, and (2) ability to exercise to exhaustion without exacerbation of symptoms, and (3) confirmed by a physician based on a structured physical exam.
Postoperative brain damage and neuropsychological disorders have been observed in 30 - 80 % of patients after heart surgery with the use of cardiopulmonary bypass (CPB).They can persist up to a year after cardiac surgery and are associated with increased hospital mortality and prolonged intrahospital stay. Hypoperfusion,hyperthermia,atrial fibrillation,genetic predisposition and systemic inflammatory response associated with CPB have been identified as pathophysiological mechanisms.However, some authors consider cerebral embolisation to be the prevalent mechanism of intraoperative brain injury after cardiac surgery,as gaseous or solid cerebral emboli can cause ischemia, inflammation and edema,consequently causing cerebral infarctions usually resulting with stroke,coma,encephalopathy, delirium and cognitive decline. Additionally,they may impair cerebrovascular reactivity (CVR). Aortic valve replacement (AVR) preformed by full sternotomy is the standard approach in the treatment of aortic valve disease. Minimally invasive (MIS) aortic valve replacement has been shown to reduce postoperative mortality, morbidity, and pain while providing faster recovery, a shorter hospital stay, and better cosmetic results. However, due to technically more demanding procedure, MIS may lead to prolonged CPB time and incomplete de-airing of the heart with an increased risk for cerebral gas embolization. Therefore, the choice of MIS might bear an augmented risk for brain injury. Transcranial Doppler (TCD) enables real time detection of intraoperative emboli in the cerebral arteries seen as microembolic signals (MES), and is an essential neuromonitoring tool. Several studies demonstrated correlation between the number of MES and the occurrence as well as severity of postoperative neurological complications. However, the factors contributing to brain injury have not been elucidated in those studies. The investigators speculate that impairment of CVR is an important mechanism that persists and prolongs the duration of brain injury into postoperative period. The aim of the study is to compare two surgical approaches used for AVR, with focus on the number of MES and their impact on levels of protein S100B (marker of brain tissue damage),postoperative CVR and cognitive function With the results,the investigators aim to help surgeons in selecting the appropriate technique for AVR in individual participants,as well as to clarify the effect of aortic valve surgery on the brain.
This is a study to evaluate the safety and efficacy of the IBRF ACP/MCP intervention protocol in patients with severe disorders of consciousness (SDOC).
Patients undergoing open heart surgery are at risk of suffering damage to the heart, brain and kidneys. This study is designed as a 2-by-2 randomized clinical trial with the purpose of investigating the organ protective effects of the glucagon-like-peptide-1 (GLP-1) agonist Exenatide versus placebo and restrictive versus liberal oxygenation during weaning from cardio-pulmonary bypass.
