The Biomarkers in the Hyperbaric Oxygen Brain Injury Treatment Trial (BioHOBIT)
Traumatic Brain InjuryThere are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject selection in clinical trials. However, these patients are typically intubated and sedated, limiting the utility of clinical examinations. Validated monitoring and predictive biomarkers will allow titration of the dose of promising therapeutics to individual subject response, as well as make clinical trials more efficient by enabling the enrollment of subjects likely to benefit. Glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and high sensitivity c-reactive protein (hsCRP) are promising biomarkers that may be useful as 1) monitoring biomarkers; 2) predictive biomarkers in severe TBI trials. Although the biological rationale supporting their use is strong, significant knowledge gaps remain. To address these gaps in knowledge, we propose an ancillary observational study leveraging an ongoing severe TBI clinical trial that is not funded to collect biospecimen. The Hyperbaric Oxygen in Brain Injury Treatment (HOBIT) trial, a phase II randomized control clinical trial that seeks to determine the dose of hyperbaric oxygen therapy (HBOT) that that has the highest likelihood of demonstrating efficacy in a phase III trial. The proposed study will: 1) validate the accuracy of candidate monitoring biomarkers for predicting clinical outcome; 2) determine the treatment effect of different doses of HBOT on candidate monitoring biomarkers; and 3) determine whether there is a biomarker defined subset of severe TBI that responds favorably to HBOT. This proposal will: 1) inform a go/no-go decision for a phase III trial of HBOT by providing adjunctive evidence of the effect of HBOT on key biological pathways through which HBOT is hypothesized to affect outcome; 2) provide evidence to support further study of the first monitoring biomarkers of severe TBI; 3) increase the likelihood of success of a phase III trial by identifying the sub-population of severe TBI likely to benefit from HBOT; 4) create a repository of TBI biospecimen which may be accessed by other investigators. This study is related to NCT04565119
The EBC Recovery Study
Traumatic Brain InjuryThe purpose of this research study to find out if clinically unconscious acute traumatic brain injury patients that show brain activation on electroencephalogram (EEG) (bedside test) have better results and wake up in the future.
Real World Testing of a Brain-Computer Interface
Amyotrophic Lateral SclerosisBrain Stem Stroke3 moreThe goal of this project is to test a new AAC-BCI device comparing gel and dry electrode headgear used for communication while providing clinical care. Innovative resources will be employed to support the standard of care without considering limitations based on service billing codes. Clinical services will include AAC assessment, AAC-BCI device and treatment to individuals with minimal movement due to amyotrophic lateral sclerosis (ALS), brain stem strokes, severe cerebral palsy, traumatic brain injury (TBI) and their family support person. This is a descriptive study designed to measure and monitor the communication performance of individuals using the AAC-BCI, any other AAC strategies, their user satisfaction and perceptions of communication effectiveness, and the satisfaction of the family support persons.
The Value of Multimodal MR Imaging in Cognitive Assessment of Patients With Moderate Traumatic Brain...
Brain InjuriesThe goal of this observational study is to learn about in The value of multimodal MR Imaging in cognitive assessment of patients with moderate traumatic brain injury. The main question it aims to answer is: • The construction of the core injury model of cognitive impairment caused by moderate brain trauma takes multi-parameter MR scanning as the main line of research, centering on the analysis of cognitive impairment of white matter structure damage and brain function involved in the research institute, and conducts research on key scientific issues such as the validity verification of cognitive prognosis after moderate brain trauma. Participants will be collected for MR, hematology and stool and neuropsychological Scale indicators in the study.
Brain Injury Self-Efficacy Scale Validation
Traumatic Brain InjurySelf EfficacyThe purpose of this study is to validate the Brain Injury Self-Efficacy Scale as a measure of self-efficacy in brain injury by comparing it with other measures of self-efficacy, the GSE, and PROMIS self-efficacy.
The Utility of Thromboelastography in Traumatic Brain Injury
Traumatic Brain InjuryCoagulation DisorderHemocoagulation disorder is recognized to have crucial effects on hemorrhagic or ischemic diseases. Coagulation-related damages secondary to traumatic brain injury are common and severe secondary insults of head trauma and often leads to a poor prognosis. In this study, we sought to assess if posttraumatic hemocoagulation disorders determined using thromboelastography are associated with coagulation-related damages secondary to traumatic brain injury, and evaluate their influence on outcome among patients with head trauma. Based on above results, prediction models or risk scoring systems will be further developed and validated to predict coagulation-related damages secondary to traumatic brain injury.

Evaluation of the Impact of a Dietary and Nutritional Intervention on Persistent Post-concussive...
Brain Injury Traumatic MildConcussions affect thousands of Canadians every year. Although the effects are usually temporary, 10-15% of adults experience persistent symptoms likely to last several weeks or even months. It is suggested that nutritional interventions should be considered in concussion management because nutrition can act on several mechanisms of brain injury. However, to date, no study has assessed the impact of dietary interventions on the recovery of people with persistent post-concussive symptoms. This randomized controlled trial aims to determine the impact of a dietary and nutritional intervention on the physical, cognitive, behavioural and emotional symptoms of patients with persistent post-concussive symptoms in New Brunswick, Canada. Patients will be randomized to one of three groups: 1) dietary treatments and nutritional supplements (experimental group A), 2) nutritional supplements (experimental group B), and 3) physiotherapy treatments (control group). Patients in group A will receive four consultations with a dietitian over eight weeks, in addition to conventional physiotherapy treatments. These patients will receive nutritional counselling and omega-3, vitamin D and creatine supplements. Patients in group B will be prescribed the same supplements as those in group A by their doctor and receive physiotherapy treatments. Finally, patients in the control group will only receive physiotherapy treatments. Patient symptoms will be measured using a questionnaire constructed from tools commonly used in practice. This questionnaire will be completed at the first physiotherapy session and 2, 4 and 8 weeks after the start of the intervention.
