Active clinical trials for "Wounds and Injuries"

As a simple auxiliary tool for lower extremity orthopedic surgery, tourniquet can effectively reduce intraoperative bleeding and ensure the clarity of the operative field, effectively shorten the operation time and improve the operation efficiency. The extensive use of tourniquets in lower extremity surgery will not only cause local paralysis, pain and other complications, but also bring about postoperative complications such as large drainage volume and deep vein thrombosis. Recent studies have found that tourniquet induced ischemia-reperfusion injury not only affects the local tissue structure and function of skeletal muscle, but also causes reperfusion injury in distant organs (such as heart, lung and brain). Therefore, improving tourniquet ischemia-reperfusion injury after knee replacement is of great significance to improve the quality of life of patients during the perioperative period. Therefore, the aim of this study was to investigate the effects of dexmedetomidine and tourniquet pretreatment on myocardial injury and brain injury caused by lower extremity ischemia-reperfusion.

Sports injuries are a very important issue for baseball players. Previous studies have found that the incidence of sports injuries faced by baseball players is continuously increasing. Sports injury rates in professional baseball, high school baseball, and college baseball players were as high as 3.6, 4.6, and 5.8 per 1,000 players, respectively. The main cause of many pitching injuries is attributed to a large number of repetitive pitches. To avoid sports injuries, it is necessary to know how to assess the risk of injury caused by repetitive pitching. Throwing is a fairly complex action that requires the coordination of the entire body. It is critical to investigate the biomechanical changes of players in order to effectively analyze such complex movements.

Overuse injuries are common among competitive Norwegian rhythmic gymnasts with a mean weekly prevalence of 37% [95% CI: 36 - 39%] and incidence of 4.2 new overuse injuries [95% CI: 3.6 - 4.9] per gymnast per year (Gram, M., Clarsen, B., & Bø, K., 2021). The knees, lower back and hip/groin were the most common injury locations. It has been postulated that reduced physical capacity (e.g strength, flexibility, stability) in the knees, lower back and hip/groin can increase the risk of injuries in rhythmic gymnastics. In addition, more than 30% of the Norwegian rhythmic gymnasts experience urinary incontinence (UI), and 70% reported that UI negatively affected sports performance (Gram, M., & Bø, K., 2020). Few of the rhythmic gymnasts had any knowledge about the pelvic floor. Hence, this assessor blinded cluster randomized controlled trial aims to find out whether the implementation of exercises targeting reduced physical capacity and pelvic floor muscle function can prevent/reduce the prevalence of overuse injuries and UI.

Chemotherapy and radiation used in patients undergoing bone marrow transplant (BMT) disrupts the endothelial lining (a thin layer of cells inside the blood vessels) which is found all throughout the body including the kidney, heart, lungs, and intestines. Disruption of this endothelial lining can lead to complications such as graft-vs-host disease (GVHD), thrombotic microangiopathy (TMA) and veno-occlusive disease (VOD). The purpose of this research study is to help investigators see if pravastatin is safe and well tolerated in patients undergoing BMT to see if it will reduce endothelial injury after BMT. The investigator hypothesizes that prophylactic pravastatin in pediatric allogeneic hematopoietic stem cell transplant recipients with elevated BMI is safe and feasible.

Justification: Studies in recent years have shown that suffering an episode of acute kidney injury (AKI) is an independent risk factor for developing chronic kidney disease (CKD), which is associated with cardiovascular complications, increases medical care costs, and decreases survival. These AKI to ERC transition cases add to the growing number of CKD cases already being seen globally. It is for them that in recent years therapeutic strategies have been sought to reduce or stop this process of transition from AKI to CKD. Objective: To evaluate the efficacy and safety of the use of dapagliflozin plus standard medical treatment (TMS), compared with only TMS for 21 days, in hospitalized patients with a diagnosis of severe AKI (KDIGO 3) in reducing the incidence of CKD to 18 months of follow-up. Design: Randomized, single center, open study. 100 hospitalized patients with a diagnosis of AKI KDIGO 3, without previous CKD, will be randomized to receive 10 mg of dapagliflozin every 24 h for 21 days + TMS or only TMS. During their follow-up, baseline blood and urine samples will be taken and at 3, 6, 12 and 18 months. At 18 months, the development of CKD will be assessed using the KDIGO clinical criteria and with the determination of urinary biomarkers (Serpina A3, HSP72, KIM 1 and NGAL).

There is no educational injury prevention model uniquely suited for kindergarten and first grade (K-1) students. The Teddy Bear Injury Clinic (TBIC) is a unique modification of the teddy bear clinic to facilitate classroom injury prevention teaching The TBIC will be administered to K-1 students, aged 5-7 years. Initial analysis will be descriptive and qualitative. Subsequent randomization of students to test and control groups followed by statistical analysis will be done to evaluate for effectiveness of the educational model

The purpose of this study is to examine the effects of individualized aerobic exercise regimen on recovery after traumatic brain injury (TBI).Investigators will determine if exercise facilitates recovery by facilitating neuroplasticity and decreasing neuroinflammation.

Cat bites are puncture wounds that have the potential to seed bacteria deep within the joint capsule, periosteum, and bone. The hand is the most common site of bite injuries. Pasteurella multocida is the is the most common organism isolated from the mouths of cats that can cause infections after a bite. Prophylactic antibiotics are often recommended with amoxicillin-clavulanate for 3-5 days to decrease the incidence of developing an infection. However, only one randomized controlled clinical trial consisting of 12 patients has been performed to justify this course of treatment, raising the possibility that the use of antibiotics could be reduced or even eliminated. Investigators will compare different durations of prophylactic antibiotics and a placebo control for cat bites to the hand/forearm presenting to the Emergency Department, Urgent Care, Plastic Surgery Clinic using a randomized, controlled, double-blind clinical trial. Participants presenting to the University of Missouri Hospital Emergency Department, Missouri University (MU) Healthcare Urgent Care, Plastic Surgery Clinic over the next year will be offered the chance to enroll if they meet the inclusion/exclusion criteria. For inclusion, participants will be >18 years of age, have cat bites to the hand or distal to elbow, and present within 24 hours of the cat bite injury. Participants must not present with active local or systemic infections, have received antibiotics within the past 30 days, or be immunocompromised (primary and secondary immunodeficiencies). Participants will be randomized to one of three treatment arms (placebo; amoxicillin-clavulanate 1 day; amoxicillin-clavulanate 5 days). Outcomes are the development of an infection at the location of the cat bite and/or systemic infection, adverse effects of interventions, disability assessed by Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and quality of life (QOL) assessed by HAND Questionnaire (HAND-Q) scores. Infection will be assessed at day 0, day 2, day 7+/-2, day 14+/-2, and day 30+/-2 by vital signs, laboratory values, physical examination and with an infrared and digital camera. All measures will be within the standard of care, apart from the infrared camera, QuickDASH, and HAND-Q scores. The anatomic locations of cat bites to the hand/forearm will be assessed for correlations with infections.

Photography teletransmission allow a better and optimized dispatching of patients calling an Emergency Medical Call Center (EMCC) for a mild traumatic injury. It has previously been studied for patients to whom an ambulance was sent and therefore presumed to be older or with co-morbidities. The present trial aim to evaluate in the general population, the effect of a smartphone-mediated visioconference in the dispatching of patients calling an EMCC for mild traumatic injury.

The use of contrast media (CM) poses a risk of post-contrast acute kidney injury (PC-AKI), especially among patients chronic kidney disease (CKD). International guidelines recommend intravenous (IV) hydration with isotonic 0.9% NaCl for three-four hours pre-contrast and four-six hours post-contrast. Recent studies have proven that oral hydration or no hydration is non-inferior to IV hydration in patients with mild to moderate CKD (eGFR 30-60 mL/min/1.73 m2). However, no randomized controlled trials have evaluated alternative hydration methods against the guideline-recommended hydration protocol for the prevention of PC-AKI in high-risk patients with severe CKD (eGFR < 30 mL/min/1.73 m2). Thus, the main focus of this trial is to evaluate IV hydration vs. oral hydration for their efficacy to prevent of PC-AKI in patients with severe CKD, who are scheduled for an elective contrast-enhanced CT-scan (CECT) with IV contrast-administration. Our research hypotheses consist of the following: Oral hydration with bottled tap water is non-inferior to IV-hydration with isotonic 0.9% NaCl as renal prophylaxis to prevent PC-AKI in patients with severe CKD referred for an elective IV CECT. NGAL and cfDNA are early and precise plasma and urinary biomarkers of PC-AKI with excellent diagnostic and prognostic accuracy for PC-AKI, dialysis, renal adverse events, hospitalization, progression in CKD-symptoms, and all-cause mortality.
