Neural Dynamics and Connectivity in Response Inhibition and Traumatic Brain Injury

Traumatic Brain InjuryStroke2 more

Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: To determine the parts of the brain involved in suppressing an urge to act. To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: This research study includes a screening visit and two study visits, each of which will last at least 2 hours. Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

Treadmill Training for Spinal Cord Injury

Spinal Cord Injury

This is a trial to test whether treadmill training can be used to improve the "walking" of patients with partial spinal cord injury. While on the treadmill, patients will be partially supported through the use of a specially designed harness attached to an overhead lift (also called Body Weight Supported Treadmill Training, BWSTT). Patients who enroll in this study will be randomly assigned to either the experimental group, which receives 12 weeks of this specialized treadmill training with regular physical therapy, or to the control group, which receives 12 weeks regular physical therapy. The ability of the patients to "walk" will be measured before and after treatment as well as 6 and 12 months later, using standard tests that examine mobility independence and speed of ambulation. The trial takes place across five sites in the US and Canada. Patients eligible for this trial will have had a traumatic spinal cord injury within 8 weeks of trial entry.

Supported Treadmill Ambulation Training After Spinal Cord Injury

Spinal Cord Injury

This is a randomized, controlled trial to compare supported treadmill ambulation training (STAT) to conventional gait training for improving gait speed, gait endurance, gait efficiency and muscle function in SCI subjects injured more than six months prior to start of training. Each subject will receive twelve weeks of either CGT or STAT, given as 20 minutes of training within a one-hour period per day, five days per week. These subjects will be studied baseline, 4,8 and 12 weeks of training, and three months after the end of training with a battery of tests designed to evaluate the subjects' gait and muscle function.

The Use of Post-operative NPWT Dressing in the Prevention of Infectious Complications After Ostomy...

Stoma IleostomySurgical Wound2 more

Introduction: Although negative-pressure wound therapy (NPWT) is likely advantageous for wound healing, the efficacy and safety of its prophylactic use remain unclear. We performed a Randomized Control Trial to assess the usefulness of postoperative NPWT in reduction of postoperative wound healing complications and surgical site infections after diverting ileostomy closure, in the group of patients previously operated for colorectal resection due to cancer. Materials & Methods: Prospective, randomized study will be conducted. Patients with past history of colorectal cancer laparoscopic surgery with protective loop ileostomy scheduled to undergo ileostomy closure with primary wound closure will be randomly divided into groups with or without NPWT. The primary endpoint are incidence of wound related complications (WRC) (wound healing complications witch required surgical intervention other than suture removal or dressing changing). The secondary endpoints are incidences of Surgical Site Infection (SSI) and length of postoperative hospital stay (LOS) and length of complete wound healing (CWH). Cost analysis will also be performed. In first step of this study between January 2016 and December 2018 we will asses the usefulness of one of the NPWT devices (NANOVA KCI) in prevention of WHC in established group. The second part of the study will be performed in 2 centers between January 2019 and December 2021. In this step we want to compere other NPWT devices in the same application and to confirm single center outcomes .

Evaluate the Incidence of Sacral and Heel Pressure Ulcers During Acute Care After SCI

Spinal Cord Injuries

This study evaluates the effect of the application of a five-layer foam dressing on the sacrum as well as a boot applied on the heels as preventive measures in the development of pressure ulcers in patients hospitalized with spinal cord injury. In order to study their effectiveness in preventing wounds, we will compare the number of wounds that developed on the sacrum and heels in participants with and without preventive treatments. The study will also assess the severity of pressure ulcers in participants with and without preventive treatment if they do develop. Half of the participants will receive the usual standard care for the prevention of pressure ulcers without dressing and boot, while the other half, in additon to standard of care, will also have a preventive dressing on the sacrum as well as Heelmedix boot applied alternately on each foot.

Absorption and Safety of Topical Timolol to Treat Chronic Wounds

GlaucomaOpen-Angle1 more

Topical timolol has been used primarily as eye drops to treat glaucoma for many years. Recent clinical experience has broadened its off-label use for a number of skin conditions, including slow-healing wounds. While there have been extensive safety studies performed on timolol administration to treat the eye, to date, no studies have documented absorption of timolol after applied on chronic wounds. Thus, the purpose of this study is to determine the blood levels of timolol in patients after topical administration to a chronic wound, and compare these levels with those of patients after administration of the same drug formulation on the eye for the indication of glaucoma.
