Active clinical trials for "Brain Injuries"

As a common white matter (WM) disease in preterm neonates, punctate white matter lesion (PWML) frequently leads to the abnormalities of brain development (e.g. the motor, visual and auditory disorders), even to cerebral palsy (CP) and amblyopia during childhood. However, it is lack of certain methods in identifying the prognosis of PWML. Through using various advanced MRI techniques, neuro-behavioral and visual assessments, a multicenter longitudinal study would be conducted to follow-up the PWML neonates with varying spatial-position and degree lesions. Through tracking the variations in WM microstructures from neonate period to childhood (2 years old and 3 years old), this study aims to explore (1) the potential relations between varying PWMLs and motor and visual disorders (2) the relations between WM MRI-metrics and neurodevelopmental assessment results, and thus determine the early biomarkers to identify CP and amblyopia.

The primary purpose of this prospective observational trial is to validate the Brain Gauge device as an objective tool for concussion assessment and treatment in order to determine if a method that has proven successful in 18-22 year old collegiate student-athletes will be applicable for military personnel. Overall aims of the study include: Demonstration that the Brain Gauge can objectively measure concussion in this population and thus improve concussion identification and coding. Demonstration of stronger screening for and tracking of acute concussion and documentation of concussion diagnoses, including improved tracking of recovery and greater adherence to DOD/VA Clinical Practice Guidelines for acute concussion.

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.

Traumatic brain injury (TBI) is a serious condition with high morbidity and mortality. The Glasgow score alone, assessed at the initial phase, is not enough to determine the prognosis. The aim of this study is to define and to evaluate a prognostic score for early death based on clinical and CT-scan findings in an observational retrospective derivation cohort of patients hospitalized for traumatic brain injury. This cohort will allow us to carry out a uni- and then multi-variate analysis so as to create a prognostic score for early death. We will subsequently test this score in a prospective validation cohort.

Observational study about prevalence, predictors of sodium imbalance and prognostic significance.

The CRS-R is a standardized and validated bedside assessment of conscious awareness. It is used routinely for diagnosis and prognosis of patients with disorders of consciousness (DOC) as well as in research settings. One limitation of the CRS-R is the lengthy administration time required to obtain a total score. Administration time can vary from approximately 15-30 minutes, depending on the patient's level of responsiveness. For this reason, the CRS-R is rarely administered in the acute hospital setting. Less time-consuming scales and metrics are used to assess conscious awareness in the acute hospital/ICU setting, but they lack specificity and sensitivity and have not been validated, increasing the potential for misdiagnosis. In conjunction with the developers of the Neuroscore (an unpublished, abbreviated version of the CRS-R), we have developed the CRSR-FAST and aim to test its validity, inter- and intra- rater reliability. We anticipate that, compared with the CRS-R, the CRSR-FAST will be less time-consuming to administer and score, but will maintain a high level of sensitivity to detecting signs of consciousness in severely brain injured patients.

Modifications of the human gut microbiota have been associated with different pathological conditions such as obesity, inflammatory bowel diseases and neurodegenerative diseases. Recently the " Brain-Gut Axis ", a bidirectional communication axis between brain and gut, has been described. In recent animal studies, an acute brain injury was associated with rapid modifications of the gut microbiota. In humans, traumatic brain injury (TBI) is a leading cause of death and disability. The patterns of gut and oropharyngeal microbiota following TBI are unknown. The primary purpose of this study is to characterize gut and oropharyngeal microbiota of patients with severe TBI.

This study aims to evaluate brain injuries and brain edema with non-contact DCS-Speckle multi-parameter imager.

Two-thirds of patients admitted to the Intensive Care Unit after a cardiac arrest die in the context of treatment withdrawal after a multimodal evaluation that determines an unfavorable neurological outcome. This study will evaluate the Pupillary Pain Index (PPI) in the neurological prognosis after cardiac arrest. The PPI is determined by recording of pupillary dilatation with a videopupillometer after a calibrated and incremented nociceptive stimulus on a cutaneous metamere.

Following a brain injury (BI) in addition to all other systems, there can be a failure in the control of the autonomic system activity. Heart rate (HR) has its own normal variability. Heart rate is controlled by the Sympathetic and Parasympathetic systems. Therefore, monitoring HR variability (HRV) can help us evaluate the balance of the two systems and their efficiency.Decrease in HRV was found to be in correlation with death among patients in the acute stage following ABI. Decrease in HRV is a pre-stage of HR irregularity and ventricular fibrillation.This disturbance can have a great impact on the patients health condition. In addition there was found an inverse correlation between this situation and the rehabilitation outcomes. Based on this data there is a great importance in monitoring HRV during rehabilitation among patients following BI while the patients are required to perform physical activity.The aim of this work is to check whether we can replace the traditional way of measuring HR by EKG Holter (gold standard) with a more simple,accessible tool-the POLAR watch. The aim of this work is to check if the data collected from a POLAR watch is reliable compared to the data collected from an EKG holter.
