    10. Joint Theater Trauma System (JTTS) & Joint Theater Trauma Registry (JTTR) Integrated systems approach to Combat Casualty Care Right patient, right place, right time, right care Trauma Registry Real time data, 90 dedicated personnel Data driven method of making changes Better body armor Impact of helicopter evacuation times Employment of Forward Surgical Teams Merge registry with operational data and medical record Training Research The Joint Theater Trauma System (JTTS) is an organized approach to providing improved trauma care across the continuum of the Levels of Care to trauma patients, especially in the battlefield environment. The Joint Theater Trauma Registry (JTTR) is the data repository collecting and hosting all DoD trauma related data. The mission of the JTTS is to: Establish and maintain a Department of Defense Trauma Registry System to capture data and provide information on care and outcomes of military and civilian trauma patients. Provide the Department of Defense and other authorized interests with timely and relevant information about care and outcomes of military and civilian injuries. Create a research strategy that supports reduction of morbidity and mortality in military and civilian trauma patients. Establish and maintain a trauma outcomes database to analyze and evaluate clinical decision making and measure subsequent outcomes for improving treatment modalities. Provide activities of each of the services with full and complete access to data resident in the DoD Trauma Registry. The goals of the JTTS include: Provide the ability to perform data driven battlefield level process improvement of trauma care that drives morbidity and mortality to lowest possible levels. Expand across DoD to bring trauma systems into fixed facility care as well as theater care thus enhancing readiness to provide optimal trauma care to deployed Service members. Emphasize continuous improvement in medical record documentation quality. Capture and share patient data across all levels of care to enable evaluation and adherence to theater clinical practice guidelines and standard operating procedures (SOPs). Identify training requirements, capture injury epidemiology, support research initiatives, and assess success of interventions and outcomes.

Continuum of TBI Care Determines Research Approach DHA = docosahexaenoic acid (DHA) for neuroprotection against negative consequences of blast exposures and improved recovery following blast exposure and/or traumatic brain injury HMSS = Helmet Mounted Sensor System EYE-TRAC = Ruggedized eye-tracking device, EYE-TRAC, which has been proven to rapidly and accurately detect attention and memory deficiencies in civilian mild TBI BANDITS = Biomarker Assessment for Neurotrauma Diagnosis & Improved Triage System = blood test for brain cell damage, much like the current blood test for heart damage NCAT = Neurocognitive Assessment Tool = fieldable cognitive assessment tool for detecting cognitive disruptions and aiding mTBI screening/assessment NNZ-2566 = drug to treat TBI - a portion of the naturally occurring hormone, Insulin-like Growth Factor, has demonstrated a remarkable ability to reduce non-convulsive seizures in animal studies with TBI. Phase I safety studies have shown an excellent safety profile. HBO2 = hyperbaric oxygen therapy = Intervention in which a patient breathes 100% oxygen intermittently inside a chamber that is pressurized to higher than sea level pressure SCORE = Study of Cognitive Rehabilitation Effects = A randomized treatment trial in a military population with mild traumatic brain injury incurred during deployment to OIF/OEF RTD = return to duty standards = Develop objective repeatable assessments to aid RTD decisions following mTBI DHA = docosahexaenoic acid (DHA) for neuroprotection against negative consequences of blast exposures and improved recovery following blast exposure and/or traumatic brain injury HMSS = Helmet Mounted Sensor System EYE-TRAC = Ruggedized eye-tracking device, EYE-TRAC, which has been proven to rapidly and accurately detect attention and memory deficiencies in civilian mild TBI BANDITS = Biomarker Assessment for Neurotrauma Diagnosis & Improved Triage System = blood test for brain cell damage, much like the current blood test for heart damage NCAT = Neurocognitive Assessment Tool = fieldable cognitive assessment tool for detecting cognitive disruptions and aiding mTBI screening/assessment NNZ-2566 = drug to treat TBI - a portion of the naturally occurring hormone, Insulin-like Growth Factor, has demonstrated a remarkable ability to reduce non-convulsive seizures in animal studies with TBI.

    35. 2. TBI / Concussion Prevention and Protection Two other preclinical studies are looking at prophylactic neuroprotection with nutraceuticals, though these are very early in development: Angus Scrimgeour USARIEM $206K Core: Preclinical proposal tests whether the micronutrient zinc, with proven efficacy in both rat (Yeiser 2002) and human (Young 1996) TBI studies, will also be efficacious in milder forms of TBI, or concussion. Goal is to develop a ration component that is easily administered by consumption under battlefield conditions. We will test this formulation in an animal model of mTBI that produces a controlled cortical injury to the frontal cortex in adult male laboratory rats. All treated animals will be compared to appropriate controls, based on morphological and functional outcomes that are used routinely in TBI research. Detlev Boison, Legacy Emanuel Hospital and Health Center $300K TATRC: Proposal will address two specific aims: In Specific Aim 1 (phase 1) study prophylactic effects of caffeine exposure prior to TBI. Specific Aim 2 (phase 2) will evaluate the therapeutic benefit of post-injury caffeine treatment. Mild, moderate, and severe TBI will be modeled in the rat lateral fluid percussion injury (FPI) model. First, to replicate typical caffeine use prior to injury in Soldiers, we will assess the influence of acute and chronic caffeine pre-treatment on mortality and morbidity following FPI.Two other preclinical studies are looking at prophylactic neuroprotection with nutraceuticals, though these are very early in development: Angus Scrimgeour USARIEM $206K Core: Preclinical proposal tests whether the micronutrient zinc, with proven efficacy in both rat (Yeiser 2002) and human (Young 1996) TBI studies, will also be efficacious in milder forms of TBI, or concussion.

    36. Army and Marine Corps fielded nearly 9,000 HMSS to deploying Soldiers and Marines Two versions fielded: Internal and External HMSS: Recorded helmet acceleration & pressure from impacts/explosions An exposure monitor, not a diagnostic tool Value of HMSS: Monitor/document head impact exposures Provide data for development of an objective head injury screening tool Provide data for Next Generation Combat Helmet 3. Objective Measure of Head Impact/ Blast Exposure GEN I HMSS performance problems, poor unit compliance with data downloading requirements, and data handling problems made it impossible to draw meaningful conclusions about the correlation of HMSS data with injuries   However,   HMSS fielding was the critical first step in the development of an objective head exposure monitor and rapid head injury screening tool   Demonstrated the ability to link sensor, operational, and injury data using established Joint Trauma Analysis and Prevention of Injury in Combat (JTAPIC) processes   Demonstrated the ability to translate helmet sensor data into meaningful head “doses” using a mathematical model (leveraged Navy- and National Highway Traffic Safety Administration-funded model development)   Valuable lessons learned are shaping the fielding of GEN II HMSS GEN I HMSS performance problems, poor unit compliance with data downloading requirements, and data handling problems made it impossible to draw meaningful conclusions about the correlation of HMSS data with injuries   However,   HMSS fielding was the critical first step in the development of an objective head exposure monitor and rapid head injury screening tool   Demonstrated the ability to link sensor, operational, and injury data using established Joint Trauma Analysis and Prevention of Injury in Combat (JTAPIC) processes   Demonstrated the ability to translate helmet sensor data into meaningful head “doses” using a mathematical model (leveraged Navy- and National Highway Traffic Safety Administration-funded model development)   Valuable lessons learned are shaping the fielding of GEN II HMSS

    37. 4. Head Injury Screening Diffuse axonal injury has been shown to result in deficits associated with concentration, attention, memory, and high-level functions such as planning and decision making. Deficits in visual tracking performance is one manifestation of the effect of diffuse axonal injury. This system can measure the movement of the eye as the subject tracks and predicts the movement of an object. These patterns of ocular tracking are significantly different in TBI patients from medications, sleep deprivation, normal or deliberate attempts to “fake” the results.Diffuse axonal injury has been shown to result in deficits associated with concentration, attention, memory, and high-level functions such as planning and decision making.

    39. 5. Head Injury Assessment Biomarker Assessment for Neurotrauma Diagnosis and Triage System The goal of this program is to have an objective measure of cellular damage that, together with other diagnostic information, will help guide the medical management of individuals who suffer a head injury. Researchers at WRAIR, in collaboration with neuroscientists at the University of Florida, have shown that the unique proteins in a nerve cell are spilled into the Cerebrospinal fluid when a brain cell is damaged. Some of these proteins can be measured in the blood if the test is sensitive enough. Preliminary clinical trials are showing very promising results that specific biomarkers have the required sensitivity and specificity to be clinically useful. Large scale clinical trials are planned that will hopefully lead to FDA clearance of this diagnostic test. The most mature platform to implement this test is a benchtop system, which would be feasible in a fixed medical facility. The most optimistic timeframe to FDA approval if the clinical trials continue to show positive results is 3 years from now. Milder forms of TBI are more difficult to differentiate and thus will require larger clinical trials that will take somewhat longer. Smaller devices will take more development but are more appropriate for further forward on the battlefield.

    40. BANDITS PROGRAM Biomarkers in Severe TBI Patients

    41. BANDITS PROGRAM Biomarkers in Mild TBI Patients

    42. 6. TBI / Concussion Treatment No drug currently is approved to treat TBI in humans. Researchers at WRAIR, in collaboration with New Zealand researchers, have discovered a molecule (NNZ-2566, an analog of glypromate) that is part of a naturally occurring hormone (IGF-1) in the brain. In animal models, this molecule appears to reduce the effects of a brain injury. This molecule has been well tolerated in initial safety trials and further clinical trials are currently in progress in civilianTBI patients. The FDA has agreed to an expedited approval process if studies show the positive benefit in humans that was seen in preclinical studies. However, it may take up to 5 years to complete the studies that would lead to that approval.No drug currently is approved to treat TBI in humans.
