Active clinical trials for "Brain Injuries, Traumatic"

This is a systematic literature review and meta-analysis investigating the effect of accidental hypothermia on mortality in trauma patients overall and patients with TBI specifically. Literature search will be performed using the Ovid Medline/PubMed database. Studies comparing the effect of hypothermia vs. normothermia at hospital admission on in-hospital mortality will be included in meta-analysis.

The effect of endotracheal cuff pressure measurement technique for preventing ventilatory associated pneumonia.

This is a five year multi-site, cross sectional, observational study designed to examine chronic pain and pain treatment after moderate to severe TBI.

After written consent from next-of-kin patients with severe traumatic brain injury was included from the neurointensive care unit (NICU) at Sahlgrenska university hospital, Gothenburg. Blood and CSF samples were collected during the initial 3 weeks after trauma. 1 year after trauma patients were assessed according to Glasgow outcome scale (GOS), NIHSS and Barthels. 10-15 years after trauma a repeated evaluation according to GOS was performed by telephone. Different biomarkers such as Neurofilament light, Glial fibrillary acidic protein and Tau among others, was analyzed from serum and CSF samples. Further patients were explored Apolipoprotein-E genetype (APOE). The investigators hypothesize that higher biomarkers concentrations and positive test for this gene relate to worse outcome 1-year and 10-15 years after trauma. Further that these biomarkers and genetic marker further have prognostic value on outcome 1-year and 10-15 years after trauma. Finally, the investigators want to explore the concentrations dynamics of these biomarkers in serum and CSF in the acute phase after trauma.

Researchers have developed a probe that contains infrared light sources that can illuminate the deep brain tissue of the frontal lobe. Photodetectors in the probe detect the backscattered light, which is modulated by pulsation of the cerebral arteries. Changes in the extramural arterial pressure affect the morphology of the recorded optical pulse, so analysis of the acquired signal using an appropriate algorithm could enable the calculation of the intracranial pressure noninvasively (nICP), which would be displayed to clinicians continuously. This pilot study is the first evaluation of the device in patients in who the gold standard comparator of invasive ICP was available. The acquisition of pulsatile optical signals was performed for up to 48 hours in each of the 40 patients who were undergoing invasive ICP monitoring as part of their normal medical treatment. Features of the optical signals would be analysed offline. A machine vector support algorithm would be implemented, with the aim of estimating ICP noninvasively and compared to the gold standard of synchronously acquired invasive ICP data.

The goals of the project are to evaluate a noninvasive monitor of brain metabolism and blood flow in critically ill humans. If validated, such a reliable noninvasive brain blood flow and metabolism monitor, by allowing physiologic and pharmacologic decisions based on real-time brain physiology, potentially will become an important tool for clinicians in their efforts to prevent additional brain tissue death in patients admitted with stroke, brain hemorrhage and traumatic brain injury.

In this project the investigators aim to evaluate olfactory and non-olfactory function in patients within the first 24h following a mild traumatic brain injury (acute mTBI) and compare their results to a group of age and sex matched control patients suffering from an orthopedic injury 24h prior to testing. The investigators then aim to follow them up 1 year after the trauma

This study will assess the effectiveness of a portable goggle system in the diagnosis of mild traumatic brain injury (mTBI) in athletes.

The current study was designed to investigate the change of serum ficolin-3 levels and assess the prognostic predictive effect of serum ficolin-3 levels in the patients with severe traumatic brain injury.

The purpose of this single center, longitudinal, pilot study is to provide evidence for the use of an eye tracking system as an objective tool to identify mild traumatic brain injury (mTBI) related oculomotor dysfunction (OMD) and predict the effectiveness of neurovision rehabilitation (NVR) of OMD. Eye tracking visual stimulus measurements will be compared to objective developmental optometrist (OD) diagnosis and assessments. It will be determined whether an eye tracking system can predict the presence or absence of mTBI related OMD and whether mTBI patients who have OMD based on the eye tracking system will respond positively to NVR.
