There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Patients undergoing orthotopic liver transplant will experience some degree of clinical and/or biochemical hepatic dysfunction. This early injury is known as primary graft dysfunction and varies from minor abnormalities to primary nonfunction. Prostaglandin-class drugs, including prostacyclin and its analogs, could represent an important advance toward the goal of reducing transplant related morbidity, mortality and associated costs by providing these benefits.
As a dentist, administering anesthetic to patients, especially children, proves to be one of the most difficult parts of a procedure. Pain is one of the most common symptom in dentistry, and a serious concern for the dentist. The pain of the local anesthetic injection has several causes. Of the many reasons for pain at the site of injection, the acidity of the solution is thought to be most important. This study will be measuring the effects of adding sodium bicarbonate (buffer) to local anesthetic during dental procedures. This is commonly used in medical applications but is not widely used in the dental setting. Using this biochemistry and human physiology, one can predict when buffering the lidocaine injection, a quicker response in analgesia and a decrease in pain during administration. I will be measuring the effect using several measuring devices to gauge if buffering the local anesthetic will benefit the pediatric dental patient by reducing the time it takes for the analgesic effect as well as decreasing the pain during administration. Along with time, I will be using the Wong-Baker Scale to assess the pain. This scale is standard protocol for assessing pain in the pediatric population. The pediatric dental population has aversions to dental procedures because of the associated pain produced from most procedures. If limiting the time it takes for the analgesic to take effect and decrease the pain altogether, the pediatric patient will be less likely to skip treatment therefore, increase dental health.
Despite a robust literature on the benefits of exercise for cancer survivors, most of the research to date falls in two primary areas - aerobic exercise and breast cancer survivors. The focus on aerobic training alone is a concern as resistance training is critical for building the muscle mass necessary to maintain physical function. However, concerns have been raised about the potential for higher than tolerated adverse event rates during resistance training, particularly that which is unsupervised, despite a history of safe use of resistance training in other chronically diseased patient populations. The aim of this pilot study is to demonstrate the feasibility, safety and quality of life benefit of a home-based resistance-training program among colorectal cancer survivors. The investigators will recruit n=30 men and women with stage I-III colon cancer. Participants will be randomized to a home-based exercise intervention that combines aerobic and resistance exercise. Control arm participants will receive a home-based meditation program.
Hepatic encephalopathy (HE) is a potentially reversible, metabolically caused complication of acute or chronic liver diseases such as cirrhosis. Due to the diseased liver's inability to remove toxins such as ammonia, which is produced in the gastrointestinal tract, the ammonia accumulates in the brain and causes forgetfulness, confusion, disorientation, concentration and memory problems, changes in mood, decreased alertness and responsiveness, changes in sleep habits, muscle tremors and stiffness, speech impairments, uncontrollable movements, agitation. This study will examine music as a possible external factor that could contribute to impairment in attention and progressive memory in cirrhotic patients while driving. Sustaining attention is important for learning and remembering new information, for e.g. keeping the car within lane and paying attention to cyclists and pedestrians. Prospective memory is the ability to remember to perform previously intended tasks at the appropriate time or occasion, for instance remembering the correct exit while driving on the highway. Impairment in any of these areas may result in serious consequences for patient with cirrhosis. There is evidence that some subsets of cirrhotic patients have a diminished ability to drive and significantly more motor vehicle crashes and traffic violations. In these patients, listening to music while driving may further jeopardize their driving ability, which in turn may lead to reduced quality of life and increased medical costs (from motor vehicle accidents). This is a cross-sectional study designed to determine if there is any effect of listening to music on attention and prospective memory in patients with cirrhosis. For these purposes, subjects will be asked to come for one study visit, which will last approximately 2 hours. During this visit, subjects will undergo a series of screening procedures (consent, assignment of subject identification number, demographics, medical history, physical examination, vitals, height, weight, and eligibility assessment). If they are found eligible, subjects will undergo several neuropsychological assessments to measure any effect of music on attention and prospective memory. These assessments include including Number Connection Test (NCT), Digit Symbol Test (DST), Cambridge Prospective Memory Test (CAMPROMPT) and Inhibitory Control Test (ICT).
The purpose of this study is to evaluate the efficacy of TXA127 to reduce the incidence (Grade II-IV) of acute Graft-vs.-Host Disease (aGVHD) in adult subjects undergoing allogeneic peripheral blood stem cell transplantation (PBSCT). The study will also evaluate the effects of TXA127 on incidence, severity and duration of mucositis; neutrophil engraftment and platelet recovery; platelet transfusion requirements; immune reconstitution; and duration of corticosteroid use. TXA127 has shown to be well tolerated by patients and appears to induce rapid production of neutrophils and platelets in the bloodstream, as well as increase the immune system components. TXA127 has also been shown reduce the severity of chemotherapy-induced mucositis.
The purpose of this study is to evaluate the efficacy of TXA127 to reduce the incidence (Grade II-IV) of acute Graft-vs.-Host Disease (aGVHD) in adult subjects undergoing double umbilical cord blood transplantation (UCBT). The study will also evaluate the effects of TXA127 on incidence, severity and duration of mucositis; neutrophil engraftment and platelet recovery; platelet transfusion requirements; immune reconstitution; and duration of corticosteroid use. TXA127 has shown to be well tolerated by patients and appears to induce rapid production of neutrophils and platelets in the bloodstream, as well as increase the immune system components. TXA127 has also been shown reduce the severity of chemotherapy-induced mucositis.
The purpose of this study is to find out if direct peritoneal resuscitation (DPR) (putting a sugar solution into the abdominal cavity) helps blood flow through vital organs in the body that may suffer from low blood flow due to surgery. We will also try to find out if the DPR will help patients recover faster from liver surgery. Lastly, this study will also try to find if direct peritoneal resuscitation decreases levels of signaling chemicals in the blood called 'cytokines' and a protein called high-mobility group protein 1, which is known to cause tissue damage.
This study is to investigate the use the adjustable gastric band for the treatment of obesity in adolescents.
Pulmonary arterial hypertension (PAH) is a progressive disease that results in severe activity limitation and death. There are few treatments for PAH and the available medications are expensive, difficult to administer and have significant toxicities. (-)-Epicatechin is a non-toxic compound that naturally occurs in foods such as tea, wine and chocolate. Clinical intervention studies using dark chocolate in normal volunteers and subjects at risk for or with established cardiovascular disease have demonstrated improvements in peripheral and coronary vascular endothelial function, blood pressure, lipids, glucose tolerance and inflammatory markers. Our study intends to examine the hemodynamics effects of purified (-)-epicatechin in subjects with pulmonary arterial hypertension. We hypothesize purified (-)-epicatechin will reduce pulmonary vascular resistance in patients with pulmonary arterial hypertension.
Patients undergoing Cesarean delivery (C-Section) with a body mass index of 30 or less will be given either 2 grams or 4 grams of an antibiotic before surgery. The antibiotic is intended to prevent infection from the surgery. It is unknown what the best dose for the usual medicine used for this purpose (an antibiotic medicine called cefazolin). Samples of the tissue just under the skin will be biopsied at the time the incision is made and at the time the cut is stitched or stapled closed. A sample of the muscle of the womb will be taken as the womb is stitched closed after the delivery. Blood tests will be done at the start and end of surgery to test the antibiotic level. A blood sample will be taken from the umbilical cord after the baby has been delivered and the umbilical cord has been cut. The umbilical cord blood sample will be tested for the antibiotic level. These tests will be used to find out if the usual dose of medicine is enough or if more medicine is needed to prevent infection in normal weight women undergoing c-sections.
