Active clinical trials for "Brain Injuries, Traumatic"

Iatrogenic withdrawal symptomes has been associated with prolonged mechanical ventilation and the and the derived symptoms such as fever and agitation has been shown to cause significantly prolonged ICU and hospital length of stay. The incidence of IWS in the adult general ICU ranges from 16,7-55%. To this date, the incidence of IWS has not been studied in patients with TBI.

Traumatic brain injury (TBI) is a major public health issue, and intracranial hypertension in the acute phase remains a critical scientific issue. Many patients with acute closed TBI received conservative, non-surgical treatments at first, while 5%~19% of which develops intractable intracranial hypertension that requires emergent surgery. Therefore, it is of great clinical significance to identify patients who are at high risk of deterioration in the early stage. Previous studies have found that brain compliance is a contributive factor to intracranial pressure, and might serve in the development of intracranial hypertension after TBI. We made assumption that intracranial pressure has a negative relationship with brain compliance providing that the volume of hematoma remains constant. However, few studies have applied magnetic resonance elastography (MRE) in evaluating brain compliance in patients with TBI. Therefore, this study is designed to enroll patients with acute closed traumatic brain injury who are initially treated non-surgically. Magnetic resonance elastography (MRE) sequences are performed to non-invasively assess patients' brain compliances, in the hope of exploring the potential value of MRE biomarkers to predict the short-term outcome in patients with acute closed TBI who are initially receive non-surgical treatments.

In this study, the single-cell transcriptome sequencing technology was used to study the transcriptome differences at the single-cell level in normal human brain, aging human brain, and epileptic brain.

The main goal of the present study is to challenge the hypothesis that blood- brain barrier disruption following brain injury increases the risk for long-term disability, development of brain dysfunction, epileptic seizures and neuroanatomical alterations.

The purpose of this study is to: Determine the temporal course of matrix metalloproteinase (MMP) expression in patients wiht severe traumatic brain injury Determine the temporal course of the expression of MMP-related inflammatory mediators of secondary injury in patients with severe traumatic brain injury Describe the association of physiological changes and standard microdialysis analyte measures (lactate, pyruvate, lactate/pyruvate ratio, and glucose) to MMP and neuroinflammatory marker concentrations.

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.

Microbiome studies may be highlighted as crucial in the development of depression for TBI patients. The microbiota-gut-brain connection may further provide an opportunity for microbiota manipulation to treat the TBI patients with depression.This study is to investigate whether exist the relationship between depression and circadian rhythm of patients with TBI or not and focus the study on the potential of the host-microbiota interaction in regulating depression.

In the current study the investigators intend to evaluate the mode of anesthesia on ischemia modified albumin and outcome in patients with traumatic brain injury undergoing emergency craniotomy

The purpose of this research study is to evaluate whether data made by the ClearView System can be used to detect whether someone has a traumatic brain injury and how severe the injury is.
