This project is to evaluate sensitivity and specificity of hyperpolarized 13C-pyruvate as imaging agents of altered cerebral glycolysis and mitochondrial dysfunction and assess pyruvate utilization in mitochondria in Traumatic Brain Injury (TBI) patients.
The purpose of this study is to evaluate the antipyretic effect of bromocriptine in critically-ill patients with acute neurologic injury and fever from infectious and non-infectious etiologies.
Traumatic brain injury (TBI) affects 1.7 million people in the United States each year, resulting in 2.5 million emergency department visits, 280,000 hospitalizations, >50,000 deaths, and more than $60 billion in economic cost. TBI also affects >30,000 military personnel annually and almost 8% of veterans who received care between 2001 and 2011. Post-traumatic neurologic outcome depends on the severity of initial injuries and the extent of secondary cerebral damage. Ischemia is the most common and devastating secondary insult. Ischemic brain damage has been identified histologically in ~90% of patients who died following closed head injury, and several studies have associated low cerebral blood flow (CBF) with poor outcome. Specifically, CBF of less than 200 ml/min has been shown to be the critical lower threshold for survival in neurointensive care patients. In addition to intracranial hypertension and cerebral edema, systemic hypotension and reduced cardiac output contribute substantially to posttraumatic cerebral ischemia. Additionally, the carotid artery is the most common site of blunt cerebral vascular injury (BCVI), which may further compromise CBF and cause subsequent death or debilitating stroke. Specifically, high grade internal carotid arterial (ICA) injuries are associated with the highest mortality and stroke rate. The investigators' goal is to develop of a wearable noninvasive, continuous, automated ultrasound sensor to accurately measure extracranial ICA flow volume. In doing so, the investigators aim to enable early detection of CBF compromise, thereby preventing secondary ischemic injuries in TBI patients. To achieve this goal, the investigators plan to first build a prototype wearable ICA ultrasound senor with integrated signal processing platform, then test its accuracy in an in vitro system and healthy human subjects.
This study was conducted in two parts: 1. This first part was designed to determine thiopentone dose requirement for induction of anaesthesia with and without the use of Bispectral Index monitoring - Participant and Care Provider in appropriate study arm blinded. 2. As a secondary outcome, Bispectral index monitoring was used to observe changes in neuronal function in intraoperative period as well as haemodynamic changes intraoperatively - Participant and Care Provider blinded.
This study will examine the efficacy of an emotion regulation intervention delivered online to individuals with Traumatic Brain Injury (TBI) with deficits in emotion regulation. 104 subjects will be enrolled and will receive 24, 60-minute emotion regulation skills-training sessions twice a week for 12 weeks, delivered online in a group video-conference with 3-4 other participants. Participants will be asked to complete an online survey, lasting approximately 40-50 minutes, every four weeks during the intervention and 12-week follow-up phase. Attendance and compliance will be tracked, and outcomes will be monitored using online data collection methods.
The long term goal for the Traumatic Injury Research Program (TIRP) is testing of novel devices for the identification and longitudinal assessment of traumatic brain injury (TBI). DoD (United States Department of Defense) has now tasked TIRP with the test and evaluation of these devices to assess reliability and validity. The objective of this effort is to test the reliability of the NKI, Inc, (NeuroKinetics, Inc) i-PAS device using a test/re-test protocol with healthy controls. The research design is test/re-test, with three assessments obtained on three separate visits. This will allow the assessment of reliability of both the device and the measure(s) that are computed from the input signals. Participants will be Healthy Controls (HC) as defined in the inclusion exclusion section. In this initial study, investigators will be administering standardized self-report instruments (Standard Form 36 - SF36, and Symptom Checklist 90r, or SCL-90r), standard three-lead EKG. In addition they will administer the NKI i-PAS specific protocol as delineated by NKI.
Traumatic brain injury (TBI) is one of the most frequent injuries affecting service members. Unfortunately, current neurocognitive assessment tools are unable to reliably detect mild TBI more than a few days post- injury. Therefore, development of advanced systems for assessment and diagnosis of TBI are a top priority within Department of Defense. This project aims to evaluate a combined electroencephalography (EEG) and eye tracking system capable of assessing compromised cognitive function stemming from TBI, with the goal of enhancing operational readiness and aiding in diagnosis, improving health care and rehabilitation for affected military personnel.
This multi-site study will examine patients with epilepsy (ES) following head injury [i.e., posttraumatic epilepsy (PTE)] and posttraumatic psychogenic Non-epileptic seizures (PNES) and will compare them to patients with traumatic brain injury (TBI) who do not have seizures using functional neuroimaging.
To prospectively evaluate the tools, environment and resources to compare the effectiveness of two different standard of care vestibular rehabilitation approaches in a military cohort with post-concussive vestibular symptoms.
Each year, about 2.8 million people sustain a traumatic brain injury (TBI) in the United States, and at least 25 percent of these injuries are classified as moderate to severe. Nearly half of those hospitalized for TBI have long-term disability. Most have psychological, physical, social, or work-related problems, which often become chronic. By talking with patients and family members, we found that returning to daily activities and regaining quality of life are major concerns. Outcomes are affected by the type and severity of the TBI, but the type of treatment someone with TBI receives is also important. What resources are available, whether providers are experienced with the problems associated with TBI, and how much treatment is available can affect outcomes as well. Currently, inpatient rehabilitation professionals are told to give people with TBI information, reassurance, advice, and referral resources. Some promising ways of helping people with TBI include using telephone and other mobile devices to reach patients after they leave the hospital, to regularly assess their individual needs and help them coordinate their health care, and to provide the information and resources that they need. These new strategies may lead to earlier return to activities and improved quality of life. No studies have compared the standard approach to discharge care with an approach that uses telecare to provide information and care coordination after discharge from inpatient rehabilitation for TBI. The main goal of this project is to find out how improving the transition from the hospital to outpatient care can improve the lives of people with moderate to severe TBI and achieve better results that are important to patients with TBI, their families, and healthcare providers. In this study, patients with TBI who are discharged from inpatient rehabilitation at one of six national TBI Model Systems sites (University of Washington, Indiana University, Ohio State University, Mount Sinai Hospital, Moss Rehabilitation, and Baylor Institute for Rehabilitation) will be randomized (like the flip of a coin) to either the standard discharge plan or the standard discharge plan with additional telephone follow up for the first 6 months after discharge. The project team will compare patient and caregiver functioning and quality of life at 3, 6, 9, and 12 months after hospital discharge in these two groups.
