Active clinical trials for "Brain Injuries, Traumatic"

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 In conjunction with the developers of the Neuroscore (an unpublished, abbreviated version of the CRS-R), we have developed the CRSR-FAST and aim to test its validity, inter- and intra- rater reliability.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.

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

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.

This study will test if patients with moderate to severe traumatic brain injuries also have endocrine abnormalities, examine any existing relationships among fatigue, depression and endocrine abnormalities, and the relationship between endocrine abnormalities, quality of life, and community integration.

This study aims at understanding irony comprehension ability of Chinese speaking patients with TBI through a series of self-made stories. Each story contains two characters having a conversation, and one of them would give a figurative (which is, ironic) or literal statement at the end of the story. The participants are asked to figure out its meaning.

This study uses a Doppler ultrasound technique being developed at the University of Leicester called 'Brain Tissue Velocimetry" (Brain TV), to investigate brain tissue motion over the cardiac cycle.

The aim of this study is to present the Turkish version of miniBESTest which evaluates the reasons of balance deficit and postural control. Accordingly, a practice of validity and reliability on adult patients with sensoriomotor impairments will be performed by utilizing the Turkish version of miniBESTest in this study.

Severe Trauma Brain Injury (TBIs) is a public health problem and monitoring of Intracranial Pressure (ICP) is a determinant key of it prognosis. Within the noninvasive methods to estimate the ICP, the measurement of intraocular pressure has been proposed because of its biological plausibility (proximity of the eye to the encephalic contend). Objective. Correlate intraocular pressure with ICP in children with TBIs and obtain their utility values.

Traumatic brain injury (TBI) is a major cause of morbidity and mortality in the US. The CDC states that 1.7 million people sustain a traumatic brain injury each year, with death occurring in 52,000 of these injured patients. It is also estimated that 275,000 yearly require hospitalization. The costs of TBI can be devastating to our society, with the 2010 economic cost estimated to be approximately $76.5 billion. 90% of this cost involves fatal or hospitalized brain injured patients. Furthermore, survivors of traumatic brain injury have high rates of institutionalization, readmission, and disability. The prediction of prognosis in severe TBI is a difficult problem for physicians. Prognosis evaluation in the acute phase of care varies widely among physicians caring for these patients[3]. With prognosis often in doubt, physicians have difficulty leading families and patients toward the most appropriate treatment which often leads to expensive testing and patient management. The Brain Trauma Foundation has recommended several early indicators of prognosis in severe TBI, including age, hypotension, CT scan features, Glasgow Outcome Scale score, and pupillary diameter with light reflexes. Pupillary diameter and light reflexes have been extensively studied, however accurate measurements of these prognostic factors have not been performed due to a lack of standardized measuring procedure. A new device has been validated to measure both pupil size and reactivity using infrared pupillometry. This device has also been studied to create the Neurological Pupil Index (NPi) as a measure of pupillary reactivity. The NPi has been shown to correlate with intracranial pressure readings, however there are no studies correlating the pupillometer findings with outcome measures in TBI. This study will prospectively evaluate the pupillometer readings of pupillary size and reactivity (NPi) to test the hypothesis that the NPi is a realiable predictor of 30-day outcomes in patients with severe TBI.
