Filter by:Investigators will measure cerebrovascular reactivity (CVR) using functional near-infrared spectroscopy (fNIRS) and magnetic resonance imaging (MRI) during the chronic phase after repetitive mild traumatic brain injury (rmTBI) as a biomarker of traumatic cerebrovascular injury (TCVI). We hypothesize that CVR will be decreased in patients with rmTBI and that these decreases will correlate with clinical outcomes. Furthermore, we predict that 5 week administration of a phosphodiesterase 5 (PDE5) inhibitor, sildenafil citrate, will augment CVR in patients with a history rmTBI.
To decrease emotional self-awareness deficits and improve emotional self-regulation, particularly anxiety, anger, depression, and positive affect, through the treatment of alexithymia.
The purpose of this study is to examine the effects of exercise on recovery after traumatic brain injury. Investigators will determine if exercise enhances rehabilitation by increasing substances (proteins) that can facilitate recovery.
The aim of the study is to investigate the effectiveness of motor and cognitive virtual environment rehabilitation on upper limb function in sub-acute patients after an acquired brain injury.
The LITES Network is an operational trauma center consortium which has the expertise, track record and confirmed capabilities to conduct prospective, multicenter, injury care and outcomes research of relevance to the Department of Defense (DoD). Hemorrhage and Traumatic Brain Injury (TBI) are responsible for the largest proportion of all trauma-related deaths. It is the poly-trauma patient who suffers both hemorrhagic shock and traumatic brain injury where a paucity of evidence exists to direct treatment, limiting the development of beneficial trauma practice guidelines. The use of Whole Blood (WB) for early trauma resuscitation has been touted as the 'essential next step' in the evolution of trauma resuscitation. Despite its historical and more recent use, little is known regarding WB's benefit relative to the 'current practice' ratio-based blood component therapy in the acutely bleeding patient, and even less is known regarding its effects in patients with TBI. AIM#1: Evaluate patient centered outcomes associated with early whole blood resuscitation practice as compared to component resuscitation in poly-trauma patients with hemorrhagic shock and further characterize outcome benefits in those with traumatic brain injury. AIM#2: Characterize blood pressure and resuscitation endpoints during the acute resuscitation phase of care and the associated/attributable outcomes for traumatic brain injury in patients with hemorrhagic shock. General Hypothesis #1: Whole blood resuscitation will be associated with improved mortality and resuscitation outcomes in poly-trauma patients and long term neurological outcome in those patients with traumatic brain injury as compared to those resuscitated with component therapy. General Hypothesis #2: Differences in prehospital and acute phase resuscitation systolic blood pressure will be associated with differential outcomes in patients with traumatic brain injury at discharge and at 6 months. Study Design: The LITES network will perform a multicenter, prospective, observational cohort study over a 4 year period to determine the impact of whole blood resuscitation in trauma patients with hemorrhagic shock at risk of large volume resuscitation with and without TBI. Early whole blood resuscitation will be compared to standard component resuscitation. The study will also further characterize blood pressure and resuscitation endpoints in poly-trauma patients with traumatic brain injury. Six Trauma sites with appropriate characteristics will be selected from 12 LITES Network sites across the country. Study Setting: The study will be performed utilizing busy level I trauma centers within the LITES Network located across the country, at sites where either whole blood has currently been incorporated into standard of care or where component blood transfusion is being utilized for patients in hemorrhagic shock at risk for large volume resuscitation. Study Population: The study will focus on patients who suffer blunt or penetrating injury, transported to a SWAT participating LITES trauma center with evidence of hemorrhagic shock at risk of large volume blood resuscitation.
The purpose of this study is to find out whether the Home-based Arm and Hand Exercise (HAHE) program improves functions of the upper limb that is affected after traumatic brain injury. HAHE is made up of exercises that simulate real-life tasks.
Traumatic Brain Injury (TBI) is one of the leading causes of death. Severe TBT is correlated with an exaggerated stress response due to plasma catecholamine levels known as sympathetic storming. It is also autonomic dysfunction syndrome. This phenomenon is also associated with brain tumors, severe hydrocephalus and subarachnoid hemorrhage. Patients are presented by tachycardia, tachypnea hypertension, diaphoresis, dystonia, hyperthermia, and dilated pupils with elevated levels of plasma catecholamine and blood glucose .
Rationale Prolonged mechanical ventilation (MV) is common in patients with severe Brain Injury (BI). Guidelines for the management of extubation are largely lacking for patients with BI, and the role of tracheostomy is highly uncertain. More important, data on practice of management of extubation is yet underreported, as is the use of tracheotomy in this specific subset of critical care patients. Objective The objective of this prospective observational study is to describe the management of extubation and tracheostomy in intensive care unit (ICU) patients with BI. The aim is to describe the incidence of extubation failure and the rate of tracheostomy. Study design The "Extubation strategies in Neuro-Intensive care unit patients, and associations with Outcomes (ENIO)" is an observational multicentre international cohort study. Study population The investigators will include patients undergoing BI, with an initial Glasgow Coma Score ≤ 12 and with a delivered duration of mechanical ventilation (MV) ≥ 24 hours at ICU admission. The inclusion period will last 6 months in total, and each centre is expected to include at least 24 patients during this period. With over 60 ICUs participating worldwide, we expect to include 1500 patients. Main parameters Parameters to be collected include: general neurological management, ventilatory management, general ICU complications, specific data on extubation and tracheostomy, general in-ICU outcomes and in-hospital mortality. Nature and extent of the burden and risks associated with participation Because of the observational design of the study using routinely collected data, there is no additional burden for the patient. Collection of data from ICU charts and/or (written or electronic) medical records systems bears no risk to the patients.
Investigators will determine the long-lasting effects of post-acute rehabilitation after traumatic brain injury and stroke. Investigators will also evaluate if the beneficial effects of rehabilitation continue after discharge from a rehabilitative program.
This study will test the effectiveness of an intervention for Veterans diagnosed with Alzheimer's Disease (AD) or Traumatic Brain Injury (TBI) and the burden on their informal (family/friend) caregiver.
