Active clinical trials for "Wounds and Injuries"

The primary purpose of this research study is to evaluate the safety and possible harms of injecting one's own Schwann cells along with nerve auto-graft after a severe injury to a major nerve has occurred.

The purpose of this study is to test the preliminary effects of an 8-week mobile application-based program (SupportGroove) developed for persons with spinal cord injury and their romantic partners.

Intraspinal pressure monitoring has been advanced as a potential technique for evaluating spinal cord perfusion after traumatic spinal cord injury. In this study, the investigators aim to validate the technique for insertion of a fiberoptic pressure monitoring device in the subarachnoid space at the site of injury for measurement of intraspinal pressure and spinal cord perfusion pressure. The primary objective of this study is to validate the methodology of invasive intraspinal pressure monitoring to derive parameters for optimal spinal cord perfusion pressure, spinal cord reserve capacity and spinal reactivity index using data obtained during the patient's stay in the intensive care unit. Secondary objectives of this study will be to a) evaluate the safety of invasive intraspinal pressure monitoring, b) prospectively evaluate the overall relationship between spinal cord perfusion pressure and functional outcomes in patients with acute traumatic spinal cord injury and c) evaluate the relationship between spinal cord perfusion pressure, motor evoked potentials and functional outcomes after incomplete spinal cord injury.

The goal of this mechanistic clinical trial is to learn about the effects of medications called soluble guanylyl cyclase stimulators on vascular function and markers of kidney and brain injury in patients having heart surgery. The main questions it aims to answer are: Does soluble guanylyl cyclase stimulation improve blood vessel function compared to placebo? Does soluble guanylyl cyclase stimulation decrease markers of kidney injury and brain injury compared to placebo? Participants will be randomized to a soluble guanylyl cyclase stimulator called vericiguat or placebo, and researchers will compare vascular function and markers of brain and kidney injury to see if vericiguat improves vascular function and reduces markers of injury. This will provide important information to determine the underlying reasons that patients have some kidney and brain function problems after having heart surgery.

This study is designed to answer questions related to safety and preliminary efficacy of Acute Intermittent Hypoxia (AIH) in Traumatic Brain Injury (TBI) survivors. First, we aim to establish whether brief reductions in inhaled oxygen concentration can be safely tolerated in TBI survivors. Second, we aim to establish whether there are any effects of AIH on memory, cognition, and motor control. Participants will be monitored closely for any adverse events during these experiments. Data will be analyzed to determine if there is an improvement in key outcomes at any dose level.

Two middle school (ages 11-14) football teams will be in Aim 1 of this study. All interested athletes on these teams will be invited to voluntarily participate in biomechanical data collection; of those enrolled, 15-20 per team will be randomly selected for instrumentation with head impact sensors. In aim 3, two youth football teams at the middle school level will be recruited to pilot an intervention developed this study. The football coaches of each team will be prospectively recruited and enrolled. All interested athletes on these teams will be enrolled; of those enrolled, 15-20 per team will be randomly selected for instrumentation with head impact sensors. Baseline and post-season neurocognitive data will be collected.

The goal of this clinical trial is to follow the progress of wounds in those with venous leg ulcers and diabetic foot ulcers while using an absorbent dressing called Mepilex Up. The main objective is to follow the progress of these wounds over time from initial visit to each follow-up visit. Participants will be asked to wear Mepilex Up dressing for up to 6 weeks of treatment or until healed, changed at every one-week interval.

The purpose of this research study is to demonstrate the safety and efficacy of using two CRS Arrays (microelectrodes) for long-term recording of brain motor cortex activity and microstimulation of brain sensory cortex.

Currently, there is evidence that structured care within the healthcare system increases the conditions for good care and better recovery. We want to investigate whether a new care concept (gero-ERAT) that combines two variants of structured care can improve the recovery of elderly patients affected by a physical trauma. Our hope is that the project will reduce the complications, short care times, fewer re-admissions and that more patients can return to regular living, which reduces the suffering for the patient and his relatives. In addition to patient benefit, a successful outcome will also result in reduced costs for healthcare and society as a whole. The concept of care is based on an increased patient participation, which is in line with the values of the Västra Götaland region and the Sahlgrenska university hospital Through the PhD project, four studies will be published. A qualitative interview study to investigate patients' experiences of care and recovery after trauma. After that, a prospective cohort survey of two groups is carried out; conventional care and gero-ERAT. Data will begin to be collected in the control group and when the control group is full geroRATAT will be implemented in the care department and we then collect data in the intervention group. Based on collected data, we will publish two additional studies one with a focus on health economics as well as one focusing on care time and recovery based on age and harvest estimation.

The purpose of this Phase I study is to conduct a pilot clinical trial using a mobile app-connected, wire-free surface electromyography (sEMG) system, called mGain, that provides biofeedback-based therapy in individuals with upper limb weakness due to neurologic injury or with upper limb amputation. Our overarching hypothesis is that the mGain wireless sEMG device and mobile therapeutic gaming environment will demonstrate improved adherence to therapy when compared to standard of care and will be feasible, acceptable, and usable in individuals with upper limb weakness or limb amputation. All participants will undertake four weeks of therapy. Conducting therapy five days a week for 30 minutes a day. In addition, participants will have an initial and final assessment visit at a study site, with each visit expected to last 1-2 hours.
