Active clinical trials for "Wounds and Injuries"

Cerebral edema is seen heterogenous group of neurological disease states that mainly fall under the categories of metabolic, infectious, neoplasia, cerebrovascular, and traumatic brain injury disease states. Regardless of the driving force, cerebral edema is defined as the accumulation of fluid in the brain's intracellular and extracellular spaces. This occurs secondary to alterations in the complex interplay between four distinct fluid compartments within the cranium. In any human cranium; fluid is contained in the blood, the cerebrospinal fluid, interstitial fluid of the brain parenchyma, and the intracellular fluid of the neurons and glia. Fluid movement occurs normally between these compartments and depends on specific concentrations of solutes (such as sodium) and water. In brain-injured states, the normal regulation of this process is disturbed and cerebral edema can develop. Cerebral edema leads to increased intracranial pressure and mortality secondary to brain tissue compression, given the confines of the fixed-volume cranium. Additionally, secondary neuronal dysfunction or death can occur at the cellular level secondary to the disruption of ion gradients that control metabolism and function. While studies utilizing bolus dosing of hyperosmolar therapy to target signs or symptoms of increased intracranial pressure secondary to cerebral edema are numerous, there is a paucity of studies relating to continuous infusion of hyperosmolar therapy for targeted sustained hypernatremia for the prevention and treatment of cerebral edema. The investigators hypothesize that induced, sustained hypernatremia following traumatic brain injury will decrease the rate of cerebral edema formation and improve patient outcomes.

This is a placebo-controlled study intended to examine the effects of the neutraceutical citicholine, together with omega-3 fatty acids, on a range of measures in individuals with concussive head injury, often referred to as traumatic brain injury, or TBI. The study will consist of three visits, during which participants will complete brain scans, a thorough testing battery and a clinical interview to assess mood and other diagnostic information relevant to the study.

Patients with impaired renal function are at elevated risk for development of contrast-medium induced acute kidney injury (CI-AKI). CI-AKI is associated with increased risk for cardiovascular morbidity and mortality. Effective CI-AKI prevention strategies are needed. The RenPro-II-WINE Trial was designed to test the hypothesis whether moderate red wine consumption prior to contrast-medium use is effective in CI-AKI prevention. Consecutive patients with impaired renal function undergoing elective coronary angiography will be assigned in one of four treatment arms: a. control patients receiving standard care b. patients receiving standard care plus red wine c. patients receiving standard care plus white wine d. patients receiving standard care plus beer This study will give important answers on how to prevent CI-AKI in patients with impaired renal function undergoing contrast media exposure.

The main objective is to study the efficacy of topical antibiotic therapy with Amoxicillin / Clavulanic acid in the prevention of surgical wound infection in patients undergoing to colorectal surgery

Background: People who have had a traumatic brain injury (TBI) often have trouble sleeping. TBI may also alter hormones, which can cause poor sleep. Researchers believe that a form of growth hormone releasing hormone (GHRH) might improve sleep in service members and veterans who have had a TBI. Objective: To see if GHRH can improve sleep in people who have had a TBI. Eligibility: Active duty service members or veterans (active duty in the past 10 years) ages 18-45 who have had a TBI in the past 6 months to 10 years. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Getting ACTH (a hormone) through an intravenous catheter (thin plastic tube) Interview about their mood and alcohol and drug use Questionnaires about their TBI, mood, and sleep Participants will have 2 overnight study visits a couple weeks apart. These will include: Physical exam Urine sample Two intravenous catheters placed. Blood samples will be taken throughout the night. Two shots under the skin of the belly. The shots will be GHRH on one visit and placebo on the other. Spending the night in the sleep lab. Their brain waves will be recorded with electrodes placed on the scalp. A questionnaire in the morning about their sleep Participants will be called a few days after each overnight visit. They will be asked about how they are feeling and to rate their sleep.

This study investigates the effect of upper extremity exercise on postprandial lipemia (PPL) in persons with spinal cord injury (SCI). Participants are measured at rest and fed a standardized meal following seated rest (CON) or arm cycling exercise (ACE). The meal is infused with "stable isotope lipid tracers" that allow for determination of the end fates of the fat in the meal.

Post cesarean section surgical site infection (SSI) is a common complication that can affect patient recovery and overall outcome. Several approaches have been studied to improve SSI rates such as timing of antibiotic administration and skin preparation. Alexis retractors have been suggested as a reasonable option to decrease SSI. However, to date there is only one randomized controlled study assessing its efficacy. The aim of this study is to whether Alexis wound retractors are beneficial in preventing cesarean section SSI.

The purpose of the study is to provide a more effective method of harvesting skin with minimal or no pain, heal more rapidly with little scarring in an outpatient setting with the use of only local anesthesia.

This study evaluates the effects of two different injury prevention exercise programs on sports-relevant performance tests and neuromuscular function in youth football players. Half of participants will receive education on an existing and previously tested exercise program, while the other half will receive education on a newly developed exercise program.

The objective of the study is to confirm the clinical relevance of the novel biomarker for traumatic brain injury (TBI) detection. Samples of blood, urine and saliva will be collected from a) patients with suspected TBI (isolated), b) patients with orthopedic injury, and c) healthy controls. The sponsor will do biochemical investigations for the samples to evaluate the presence, level and structure of the targeted biomarker.
