fMRI In Spinal Cord Injury Patient After Rehabilitation
Spinal Cord InjuryThe purpose of this study was to evaluate the potential reorganization in the sensorimotor cortex in spinal cord injury (SCI) patients after Body Weight Supported Treadmill Training (BWSTT) associated with conventional motor rehabilitation. The investigators hypothesized that training with weight bearing associated with conventional motor rehabilitation will be able to reorganize the brain.
Next Science Wound Gel Efficacy in Chronic Wound Versus Standard of Care
Wound Chronic DrainingThis is a 3 to 4 months, multi-site, prospective randomized clinical study of patients diagnosed with a chronic wound. The primary objective is to assess changes in healing rate, by measuring differences in wound area when treating chronic wounds with the Next Science Wound Gel compared to the Triple Antibiotic Ointment Neosporin (Standard of Care, SOC). At the end of the study period, patients may continue receiving their assigned study treatment provided they have signed the "Continuation of Treatment Informed Consent" and the rational for continuation is documented by the investigator.
Hyperbaric Oxygen in Lower Leg Trauma
Tibial FractureSoft Tissue InjuryStudy hypothesis :Hyperbaric Oxygen may prevent complications and improve outcomes in severe lower limb trauma. We propose to investigate this hypothesis by conducting an International multi centre randomised control trial of standard trauma/orthopaedic care with or without a concurrent course of hyperbaric oxygen treatments.
Depression and Traumatic Brain Injury
DepressionTraumatic Brain InjuryProblem: Depressive symptoms are a common mental health problem following traumatic brain injury (TBI), occurring in up to 87% of patients. Depression following TBI has important consequences including poor functioning, lack of ability to return to work and family activities and prolonged TBI symptoms. The reason depression develops in some patients following TBI is unknown, making treatment difficult. One type of brain protein that shows genetic differences between people is called the serotonin transporter. People can be divided by whether or not they have a short protein (S allele) or a long protein (L allele) which influences the amount of serotonin transporter. Serotonin is a key brain chemical in depression in many mental/psychiatric illnesses. We think that the genetic differences in the serotonin transporter, that may not make a difference before TBI, may become important after TBI due to the nature of these injuries. Methods: A consecutive sample of 200 patients attending a TBI clinic who have sustained a mild-to-moderate TBI (American Congress of Rehabilitation Medicine criteria) within the last 2 months will be assessed for the presence of major depression (standard criteria, standardized interview). In phase I, blood samples from patients with mild-to-moderate TBI with depression and without depression will be checked for the presence of the 5-HTTPR genetic difference. This will allow us to study if the S allele is more likely in TBI patients with depression. In phase II, the patients with depression will be treated with the SSRI citalopram for 6 weeks. At 6 weeks, or upon discontinuation of citalopram, depression will be assessed again. This will allow us to study if depressed patients with the S allele respond more poorly to treatment. Persons assessing depression after treatment will not know the genetic makeup of each patient. Results Expected: If the serotonin transporter genetic difference confers susceptibility to depression following TBI, this will provide important information on what causes depression following TBI and document a risk factor for depression previously unstudied in this population. Also, as SSRI antidepressants are used to treat depression in TBI, this study may identify a subgroup of TBI patients in whom different medications should be given or additional medications are required.
Trauma Reception and Resuscitation Project
TraumaTest the hypothesis that the implementation of real-time, computer-prompted algorithms in the first half hour of trauma management will result in a measurable reduction in management errors associated with the reception and resuscitation of major trauma patients. Demonstrate that a reduction in management errors will translate into a reduction in morbidity and mortality.
Prone Positioning in Pediatric Acute Lung Injury
Acute Lung InjuryThe purpose of this trial is to test the hypothesis that at the end of 28 days, infants and children with acute lung injury treated with prone positioning would have more ventilator-free days than those treated with supine positioning.
Testosterone Plus Finasteride Treatment After Spinal Cord Injury
Spinal Cord InjurySpinal Cord Injuries11 moreThe purpose of this study is to determine whether testosterone plus finasteride treatment will improve musculoskeletal health, neuromuscular function, body composition, and metabolic health in hypogonadal men who have experienced ambulatory dysfunction subsequent to incomplete spinal cord injury. The investigators hypothesize that this treatment will improve bone mineral density, enhance muscle size and muscle function, and improve body composition, without causing prostate enlargement.
OSCAR - An Internet-based Supportive Coaching for Informal Caregivers of Adult Individuals With...
CaregiversBrain InjuryThis is an intervention study for informal caregivers of adult patients with an acquired brain injury (stroke, traumatic brain injury or cerebral haemorrhage). It will determine whether an internet-based supportive coaching offers benefits to the caregivers in their own process of coping in the aftermath of a brain injury of a close relative. We expect the internet-based supportive coaching to be more effective in the treatment of emotional distress reactions and caregiver burden than the treatment as usual.
Supplemental Postoperative Oxygen and Wound Infection in Morbidly Obese Patients
Surgical Wound InfectionThe investigators propose to test the hypothesis that the incidence of major complications related to infection or inadequate healing is reduced in morbidly obese patients given 80% inspired oxygen during, and for 12-18 hours after, surgery compared with patients given 80% oxygen only during surgery. The primary outcome will be a composite of major complications plausibly related to infection or healing.
EMG Triggered Closed-Loop Stimulation for Spinal Cord Injury Individuals
Spinal Cord InjuriesMost individuals with spinal cord injury (SCI) have residual nerve circuits. The investigators aim to strengthen those circuits to improve motor recovery after injury. To do this, the investigators are attempting to pair electrical and magnetic stimulation with physical training targeted toward the connections between nerve circuits. Past studies by other groups have shown that synapse strength can be improved temporarily after a short period of paired stimulation between the brain (motor cortex) and the peripheral nerves serving target muscles - in other words, "Fire Together, Wire Together". The brain's intention to move a muscle can be read by recording surface electrical activity over target muscles (electromyography or EMG). In animal models of SCI, scientists have successfully used target muscle EMG to trigger spinal cord electrical stimulation pulses while the animals perform physical exercises. Using the body's own signals to trigger nerve stimulation is called "closed-loop stimulation". This might be an optimal method to coordinate brain and nerve activity, especially with the clinical advantage of being possible to combine with physical exercise training. However, whether EMG-triggered closed loop stimulation has the same amount of effect when applied non-invasively in humans is still unknown. This proposed study is a proof-of-principle to demonstrate the potential of non-invasive closed-loop stimulation in humans with incomplete cervical SCI. We will test different combinations of triggered and non-triggered electrical and magnetic stimulation, and record the short-term effects on nerve transmission and skilled function of hand muscles. This pilot study will be a foundation for future studies combining EMG-triggered stimulation with long-term physical exercise training.
