Effect of Increased Positive End-expiratory Pressure on Intracranial Pressure in Different Respiratory...

Acute Brain Injuries

There are concerns that the use of positive end-expiratory pressure (PEEP) for the treatment of pulmonary complications in patients with brain injury may potentially elevate intracranial pressure (ICP), and deteriorate neurological status. It is suggested that both respiratory system compliance and ventricular compliance would contribute to the elevation of ICP when PEEP increases. In theory, PEEP may cause elevation of ICP by increasing intrathoracic pressure and diminish venous return. However, the transmission of PEEP into thoracic cavity depends on the properties of the lung and chest wall. Experimental study showed that when chest wall compliance is low, PEEP can significantly increases intrathoracic pressure; whereas low lung compliance can minimize airway pressure transmission. It is generally recognized that the lung compliance decreases in acute respiratory distress syndrome (ARDS) patients due to extensive alveolar collapse. However, it has been report that the elastance ratio (the ratio between elastance of the chest wall and the respiratory system, where elastance is the reciprocal of compliance) may vary from 0.2 to 0.8. Therefore, it is important to distinguish the compliance of the chest wall and the lung when investigating the effect of PEEP on ICP. Because intrathoracic pressure (pleural pressure) is difficult to measure in clinical situations, esophageal pressure (Pes) is considered as a surrogate of intrathoracic pressure. In the present study, the investigators determine the effect of PEEP on intrathoracic pressure and ICP by Pes measurement.

Microvascular Injury and Blood-brain Barrier Dysfunction as Novel Biomarkers and Targets for Treatment...

Traumatic Brain InjuryBlood Brain Barrier Defect

Traumatic brain injury (TBI) is a leading cause of death and disability around the world. The social and economic burden of TBI is tremendous and the cost of TBI is estimated at $1 billion per year in Canada- $650 million in care and $580 million in lost productivity. Novel interventions aimed at TBI-linked molecular targets have been successful in limiting injury and improving neurologic recovery in animal models, thus providing compelling evidence that effective intervention is possible after injury. This study proposes to investigate traumatic microvascular injury (TMI) and specifically blood-brain barrier dysfunction (BBBD) as a candidate biomarker and therapeutic target in TBI.

Brain Injury Rehabilitation Improving the Transition Experience

Traumatic Brain Injury

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 from a TBI care manager 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.

HITT Device Pilot Testing for Traumatic Brain Injury

Brain InjuriesTraumatic

The purpose of this research study is to collect data from the eyes of traumatic brain injury (TBI) patients. Patients will look at a green target that will measure the fixation of the eye for 30 seconds. In that 30 seconds, the location of the green target will change and the participant is to track, with their eyes, the light as best they can. The device will measure how well fixation was maintained and the speed of the saccadic movements of the eye. Data will then be used to determine whether there is correlation between these measures and known TBI.

Study of Cerebral Tissue Oxygenation During Transfusion in Traumatic Brain Injury

TBI (Traumatic Brain Injury)Acute Brain Injuries

This proposal aims to provide some objective, non-invasively achieved, physiologically relevant data in order to provide some rational basis for decision-making for transfusion in sTBI. Specifically this proposal is an observational study of transfusion and brain tissue saturation in sTBI patients. The results will illustrate to what degree brain tissue oxygenation is critically dependent on the degree of anemia in sTBI and help in the decision of whether transfusion might be helpful.

The Neuromarker S-100B in Patients With Different Types of Intracranial Injury

Traumatic Brain InjuryTrauma

Abstract: The most widely studied neuro-markers in traumatic brain injury (TBI) are S100B and neurone specific enolase (NSE). S-100B is localized in astroglia. This marker is used to predict neuronal damage caused by traumatic brain injury. The investigators conduct a study to derive and validate the measurement of S-100B in serum of patients with different types traumatic brain injuries.

CENTER-TBI: Collaborative European NeuroTrauma Effectiveness Research in TBI

Traumatic Brain Injury

The research aims of the CENTER-TBI study are to: better characterize Traumatic Brain Injury (TBI) as a disease and describe it in a European context, and identify the most effective clinical interventions for managing TBI. Specific aims To collect high quality clinical and epidemiological data with repositories for neuro-imaging, DNA, and serum from patients with TBI. To refine and improve outcome assessment and develop health utility indices for TBI. To develop multidimensional approaches to characterisation and prediction of TBI. To define patient profiles which predict efficacy of specific interventions ("Precision Medicine"). To develop performance indicators for quality assurance and quality improvement in TBI care. To validate the common data elements (CDEs) for broader use in international settings, and to develop a user-friendly web based data entry instrument and case report form builder. To develop an open database compatible with Federal Interagency Traumatic Brain Injury Research (FITBIR). To intensify networking activities and international collaborations in TBI. To disseminate study results and management recommendations for TBI to health care professionals, policy makers and consumers, aiming to improve health care for TBI at individual and population levels. To develop a "knowledge commons" for TBI, integrating CENTER-TBI outputs into systematic reviews.
