SWIFT Study in the ED

Mild Traumatic Brain Injury

Mild traumatic brain injury (mTBI) is a prevalent and costly public health problem with disabling consequences. More than one million civilians with mTBI are treated in US hospitals and emergency departments each year (Faul, et al., 2010). While the exact number is debated, approximately 10-15% of individuals with mTBI will experience prolonged and disabling post-concussive symptoms (Stranjalis, et al., 2008; Ruff and Weyer Jamora, 2009), and 34% will experience a psychiatric illness in the first year after injury (Fann, et al., 2004). In addition, at least 188,270 military service members sustained a TBI from 2000 to mid August 2010, and nearly 77% of these injuries were mild (Defense and Veterans Brain Injury Center, 2010). Many individuals require treatment for resulting mTBI symptoms. The proposed study builds on preliminary research conducted by the investigators to develop and test the effectiveness of a social work delivered education and reassurance intervention for adults with mTBI (SWIFT-Acute) against usual care. The proposed study will assess acceptability and obtain preliminary effectiveness data for an enhanced social work assessment and intervention for adults with mTBI (SWIFT) discharged from the Emergency Department (ED). SWIFT includes early education, reassurance, coping strategies, resources and a brief alcohol use intervention in the ED plus follow up telephone counseling, needs assessment and case management referral to necessary services. The intervention targets cognitive, physical, psychiatric and functional outcomes; specifically, post-concussive symptoms, depression, anxiety, posttraumatic stress disorder, alcohol use, community functioning and successful linkage to community resources. It is hypothesized that SWIFT will be acceptable to patients and that participants in the SWIFT group will report superior outcomes on measures of post-concussive symptoms, depression and anxiety, alcohol use and community functioning and will report increased successful linkages to needed resources when compared to the SWIFT-Acute group. The specific aims of the study are: Implement an innovative social work intervention for adults with mTBI (SWIFT). Assess acceptability of SWIFT using qualitative interviews with participants. Assess preliminary effectiveness of SWIFT compared to SWIFT-Acute alone on reduction or prevention of post-concussive symptoms, depression, anxiety, posttraumatic stress disorder (PTSD) symptoms, and alcohol use, and on improvement of community functioning and successful linkage to community resources. 80 participants will be randomized to receive SWIFT or SWIFT-Acute. Preliminary intervention effectiveness will be assessed using standard measures of post-concussive symptoms, the primary outcome, depression, anxiety, PTSD, alcohol use, and community functioning. A structured survey will be used to assess linkage to community resources.

Transforming Research and Clinical Knowledge in TBI Pilot

Traumatic Brain Injury

The global aim of this proposal is to test and refine Common Data Elements (CDEs), neuroimaging standards, and best practices for genetics and proteomics in Traumatic Brain Injury (TBI) studies. Testing and validating of TBI-CDEs will be performed in a multi-center prospective observational study with 3 TBI Centers (San Francisco General Hospital (SFGH), University of Pittsburgh Medical Center (UPMC), University Medical Center Brackenridge (UMCB)) and a TBI Rehabilitation Center (Mount Sinai Rehabilitation Center (MSMC)). The investigators will create and expand existing data repositories for patient demographics, neuroimaging, plasma biomarkers, genetics, and multivariate outcomes thereby providing researchers and clinicians with the infrastructure to establish multidisciplinary, multicenter research networks and improve clinical research in the TBI field.

Transforming Research and Clinical Knowledge in Traumatic Brain Injury

Traumatic Brain Injury

The overall goal of Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study is to determine the relationships among the clinical, neuroimaging, cognitive, genetic and proteomic biomarker characteristics for the entire spectrum of TBI from concussion to coma. TRACK-TBI will validate biomarkers and outcome measures for clinical trials, advance diagnostic and prognostic models for TBI and improve clinical trial design. The Investigators are enrolling patients within 24 hours of injury who present to a TRACK-TBI site with a brain injury that meets ACRM criteria and receives a clinically indicated head CT.

Assessing Eye Tracking Features Following Sports-Related Concussion

Traumatic Brain Injury

This proposal aims to describe the oculometric features present during King-Devick (K-D) testing for subjects who experienced sports-related concussion. The investigators aim to better describe the underlying oculomotor anomalies present in this cohort that lead to increased K-D test time. Understanding these anomalies will allow for better understanding of the effects of sports-related concussion and may provide a rapid and reliable metric for diagnosing concussion as well as monitoring long-term recovery.

Electrolyte and Fluid Disturbances in Subarachnoid Hemorrhage and Traumatic Brain Injury

Electrolyte DisturbancesSubarachnoid Hemorrhage2 more

During the course of their acute illness patients with subarachnoid hemorrhage and severe traumatic brain injury often develop disturbances in their fluid balance and electrolyte homeostasis. These shifts are associated with worse outcome and increased morbidity. The aim of this observational study is to systematically analyze the incidence, characteristics, potential diagnostic markers and predisposing factors of such disturbances. The investigators hypothesize that many disturbances cannot be classified with a standard diagnostic approach and that variable fluid management contributes to their pathophysiology. Patients will be closely monitored clinically and the exact fluid and electrolyte balances will be recorded. Treatment decisions are within the bedside physicians responsibility. Baseline fluid management is standardised. No interventions are planned. The observation period equal the duration of ICU stay.

Structural and Functional Neuroimaging Studies of Combat Veterans

Traumatic Brain InjuryPTSD

Background: - Studies have shown that some people develop post-traumatic stress disorder (PTSD) after being exposed to the trauma of military combat. They may have repeated thoughts, images, and dreams of the trauma; feel detached from others; have difficulty sleeping and concentrating; or be easily startled. Some studies have also shown that after having a blow or blast to the head, some people may develop post-concussive syndrome (PCS), which may include symptoms such as headaches, difficulty concentrating, and feeling moody or irritable. Researchers are interested in using magnetic resonance imaging (MRI) to study combat veterans from Operation Iraqi Freedom or Operation Enduring Freedom in order to evaluate possible changes in the brain that may be attributed to PTSD or PCS. Objectives: - To evaluate changes in brain function in recent combat veterans that may be related to post-traumatic stress disorder or post-concussive syndrome. Eligibility: - Combat veterans of Operation Iraqi Freedom/Operation Enduring Freedom who are enrolled in Walter Reed Army Medical Center protocol 351030, have returned within the last 6 weeks from a deployment in Iraq or Afghanistan that lasted at least 3 months, and are able to have magnetic resonance imaging scans. Design: This study involves between 1 and 4 outpatient visits to the NIH Clinical Center over the course of 1 year. The second, third, and fourth visits will occur 3, 6, and 12 months after the first visit. At the first visit, participants will have a baseline MRI scan, followed by a functional MRI (fMRI) scan to see what parts of the brain are used while performing simple tasks and responding to images. Participants will complete questionnaires after the scan to report on their experiences during the MRI scan. For the remaining three study visits, participants will have further MRI and fMRI scans and will complete additional questionnaires. Participation is complete after the 12-month study visit, or following a diagnosis of PTSD, major depression, or PCS at any time during the study. No treatment will be provided as part of this protocol.

Neural Dynamics and Connectivity in Response Inhibition and Traumatic Brain Injury

Traumatic Brain InjuryStroke2 more

Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: To determine the parts of the brain involved in suppressing an urge to act. To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: This research study includes a screening visit and two study visits, each of which will last at least 2 hours. Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

PariS-TBI Study : Paris Severe Traumatic Brain Injury Study

Brain InjuryCraniocerebral Trauma1 more

The primary objective of the protocol is to study the long-term outcome of a large group of traumatic brain injury patients. This outcome is to be described in terms of activity, participation, quality of life, SOCIO-professional outcome and impact on caregivers, and in relation to health care provision. The secondary outcome is to measure the impact on functional outcome of several predictive factors, and their relative importance on outcome. Our principal hypothesis is that SOCIO-professional and health provision factors play a major role on long-term outcome, further even than initial severity of brain injury.
