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.
The most common treatment for men with high risk prostate cancer is radiation therapy (XRT) followed by long term androgen deprivation therapy (ADT). Long-term AD is toxic, with substantial metabolic, physical, mental and sexual side-effects. In this study, the investigators propose a treatment strategy to optimize the control of high risk prostate cancer by using dose-escalated external beam radiation (proton therapy or IMRT) concurrent with docetaxel and adjuvant short-course AD. The investigators hypothesize that this approach will be superior to the current standard of care and obviate the need for long term AD. In this study, subjects will be randomized to either XRT with long term ADT or XRT and chemotherapy and short term ADT.
Compare the efficacy of the 755nm Alexandrite laser to the nanosecond 755nm Alexandrite laser for the removal of unwanted tattoos using photographic evaluation and histological findings.
Study will test the use of narratives on patient satisfaction and translation of an evidence-based approach to the use of X-rays for leg injuries in the Emergency Department (ED). The investigators will identify patients with foot, ankle, or knee injuries for whom X-rays are determined to not be needed. On discharge, patients will receive the current fact-based sheet or that plus a narrative explaining the work-up and treatment of these injuries. Outcomes will be assessed by a survey measuring patient satisfaction and understanding.
The purpose of this study is to determine whether two modes of artificial (i.e. mechanical) ventilation have an impact on patient synchrony with the ventilator (breathing machine) and on the patient's work of breathing.
The investigators will be looking at the efficacy of the use of once daily use of low dose naltrexone (4.5mg) in subjects with symptomatic inflammatory bowel disease.
This is a non-randomized, non-interventional pilot observational study designed to follow high-risk patients through their surgical and hospital stay. The investigators will collect 2 4ml vial's of blood (total of 8ml) prior to surgery to assess CV biomarkers - inflammatory, metabolic, hypercoagulable and platelet.
The investigators overall hypothesis is that exacerbation of endoplasmic reticulum (ER) stress in the liver is associated with significant alterations in phosphatidylcholines that drive the NASH phenotype in obese humans. The investigators plan to examine this hypothesis in a well-characterized cohort of obese subjects that are scheduled for bariatric surgery. Methyl-D9-choline chloride will be infused before and after a 2-week high fructose or glucose feeding to determine the biosynthesis and kinetics of secretory lipoprotein phospholipids. It is proposed that phospholipid metabolism play an important role in the pathogenesis or etiology of fatty liver in non-alcoholic conditions through mechanisms that invoke ER and oxidative stress responses.
The objective of the study is to determine the efficacy and safety of Everolimus conversion in liver transplantation. Most large US liver centers transplant patients with high Model for End-Stage Liver Disease (MELD) scores. However, many of the sponsored liver transplant trials in the US do not include patients with high MELD scores making it difficult to extrapolate these trial data to the patients cared for at larger liver transplant centers. The greatest potential benefit of mammalian target of rapamycin (mTOR) inhibitors is the avoidance of the side-effects of calcineurin-inhibitors, namely, renal insufficiency, diabetes and hypertension. Therefore, this protocol is designed to study the efficacy and safety of everolimus and Myfortic in liver transplant patients with high MELD scores at two large centers with a vast experience in the administration of mTOR inhibitors.
The purpose of this study is to determine the feasibility of successfully delivering moderate intensity aerobic exercise training to depressed traumatic brain injury subjects between one and three years after injury.
The purpose of our study is to characterize the composition of the hard and soft tissues present after regenerative endodontic procedures in root canals of teeth previously diagnosed with the need for extraction for orthodontic treatment and incomplete root formation. Although the protocol addressed in this study is currently being used in clinical practice, there are no prospective clinical trials investigating its efficacy in stimulating continued root development and the nature of the newly formed tissues.
