Objectives: - To investigate the presence of cerebrospinal biochemical markers in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas. - To investigate the presence of inflammatory markers in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas. - To investigate the presence of venous gas emboli (VGE) in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas.
The prevention of secondary brain injury is a primary goal in treating patients with severe traumatic brain injury (TBI). Secondary brain injury results from tissue ischemia induced by increased vascular resistance in the at-risk brain tissue due to compression by traumatic hematomas, and development of cytotoxic and vasogenic tissue edema. While traumatic hematomas may be managed surgically, cytotoxic and vasogenic edema with resulting perfusion impairment perpetuates brain ischemia and injury. Animal models suggest that remote ischemic conditioning (RIC) can reverse these effects and improve perfusion. Based on these findings it is hypothesized that RIC will exert beneficial effects on TBI in man, thereby representing a new therapeutic strategy for severe TBI. Patients presenting to our institution suffering from severe TBI will be considered for enrollment. Eligible patients will have sustained a blunt, severe TBI (defined by Glasgow Coma Scale <8) with associated intra-cranial hematoma(s) not requiring immediate surgical decompression, with admission to an intensive care unit and insertion of an intra-cranial pressure monitor. Patients will be randomized to RIC versus sham-RIC intervention cohorts. RIC interventions will be performed using an automated device on the upper extremity delivering 20 cumulative minutes of limb ischemia in a single treatment session. The planned enrollment is a cohort of 40 patients. Outcomes of this study will include multiple domains. Our primary outcome will include serial assessments of validated serum biomarkers of neuronal injury and systemic inflammation. Secondary outcomes will include descriptions of the clinical course of each patient, radiologic assessment of brain perfusion, and neurocognitive and psychological assessment post-discharge. If clinical outcomes are improved using RIC, this study would support RIC as a novel treatment for TBI. Its advantages include safety and simplicity and, requiring no specialized equipment, its ability to be used in any environment including pre-hospital settings or in austere theatres. The investigators anticipate that TBI patients treated with RIC will have improved clinical, biochemical, and neuropsychological outcomes compared to standard treatment protocols.
This study plans to learn more about the impact of enteral nutrition on bacteria in critically ill trauma patients with brain injury. Specifically, it seeks to understand the effect that a prebiotic containing enteral feeding formula (Nutraflora scFOS in Vital AF) has on the gut, oral, and skin bacteria. A prebiotic is a special form of dietary fiber that acts as a fertilizer for good bacteria. The prebiotic Nutraflora scFOS has been cleared by the U.S. Food and Drug Administration and is not considered investigational as used in this study. Enteral feeding is a way to give nutrition to critically ill people who are unable to eat.
The objective of this study is to investigate the value of employing the aortic no-touch off-pump coronary artery bypass technique and the practice of carbon dioxide surgical field flooding for the prevention of type 1 and 2 neurological injuries following surgical coronary revascularization.
The purpose of this study is to assess the effects on upper limb spasticity of soft splints worn during three weeks three hours a day by patients with stroke or disorders of consciousness.
Randomized control trial to evaluate uni-manual and bimanual upper limb function as well as compare outcomes of varied cast wear in children with hemiplegic cerebral palsy (CP) following a hybrid camp model of modified constraint induced movement therapy (mCIMT) and hand-arm bimanual intensive training (HABIT).
The purpose of this study is to determine the sensitivity and specificity of an aid in assessment of concussion based on eye-tracking, in comparison to a clinical reference standard appropriate for the Emergency Department (ED) or concussion clinic.
Traumatic brain injury (TBI) is the most common cause of acquired disability in youth and a source of significant morbidity and family burden. Novel behavior problems are among the most common and problematic consequences, yet many youth fail to receive needed psychological services due to lack of identification and access. Linking youth with TBI to effective treatments could improve functional outcomes, reduce family burden, and increase treatment satisfaction. The investigators overarching aim is to compare the effectiveness, feasibility, and acceptability of three formats of family problem solving therapy (F-PST) for improving functional outcomes of complicated mild to severe adolescent TBI: therapist-guided, face-to-face; therapist-guided online; and self-guided, online F-PST.
The purpose of this trial is to determine the efficacy of spinal cord stimulation, using wire leads, to produce an effective cough in patients with spinal cord injuries.
This multicenter, observational, study will enroll severe neurologically injured patients both prospectively and retrospectively. The aims are to identify the percent of neurocritical care patients with sodium levels ≤ 135 mEq/L, describe treatment strategies employed, determine the correlation of clinical factors (i.e. GCS, ICP) with serum sodium concentrations in patients prior to sodium altering therapy, and evaluate outcomes through evaluation of length of stay, discharge disposition, and modified Rankin score (mRS).
