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.
This is a prospective, randomized study evaluating the efficacy of bedside ultrasound assisted lumbar puncture in pediatric patients
The purpose of this study is to to evaluate the rate of new onset postoperative atrial fibrillation in subjects receiving the amniotic membrane patch placed on the epicardial surface as compared to subjects who did not undergo epicardium intervention.
To characterize the metabolism of glucose by the leukemic cells in patients with leukemia before and after initial chemotherapy. To compare the metabolism of glucose by leukocytes in healthy volunteers and leukemic cells in leukemic patients.
Biceps pathology typically includes pain in the anterior shoulder that is reproduced with provocative maneuvers. However, optimal treatment of patient with this diagnosis is not clear and can include tenotomy (cutting the biceps) or various forms of tenodesis (cutting then reattaching). As tenotomy can lead to cosmetic deformity and anterior humeral discomfort from spasms, many surgeons perform tenodesis. There are various techniques for tenodesis. This study will compare 2 methods: suprapectoral (doing the surgery using an incision higher in the shoulder) versus subpectoral fixation (surgery which involves making an incision lower in the shoulder). Purpose of the study is to prospectively determine whether arthroscopic suprapectoral or open subpectoral biceps tenodesis results in better function.
The aim of the planned in-vivo trial is to investigate the effectiveness of the caries infiltration technique for the repression of caries progression. Within the framework of this investigation it is intended that the hypothesis to be substantiated is that carious cavities, which have been treated with the caries infiltration technique, exhibit significantly reduced radiological progression than those cavities that have been treated using standard preventive treatments. In this multicenter trial, a total of 90 test subjects are included and 45 test subjects at each institution are to be treated with both, the infiltration technique and using conventional fluoridation treatment in different sides of the mouth ("split-mouth design"). The anticipated result of this trial shall deliver information on the long-term effectiveness of caries infiltration to prevent the progression of existing approximal carious lesions, and thereby enable an improvement in caries prevention within the scope of dental treatment.
The purpose of this study is to determine the efficacy of two rapid diagnostic tests in plasma, venipuncture whole blood, and fingerstick whole blood. The clinical performance of Multiplo HBc/HIV/HCV will be determined by comparing the results with patient infected status for HIV-1/2 (human immunodeficiency viruses 1 and 2), HBV (hepatitis B virus) and HCV (hepatitis C virus). The clinical performance of Reveal HBsAg will be determined by comparing the results with patient infected status for HBV. Subject participation in the study will consist of a single one-hour visit, at which time blood samples will be drawn for testing with the investigational devices and with approved comparator assays. The test results, which are the outcome of the study, will be obtained only once, at the time of this visit.
The investigators would like to investigate the effect of chloride dosing on the development of acute kidney injury in critically ill patients. The investigators hypothesis is that administering intravenous fluids with higher chloride content are more likely to lead to acute kidney injury.
The investigators are trying to understand the role of specific genes in the function of airway surface cells. The investigators know that there are some common genetic markers that are associated with various lung diseases. However, most people with these genetic markers never develop any evidence of lung disease, so it is not understand how or if these markers play a role in disease. Investigators are asking healthy people to provide three (3) tubes of blood as well as a sample of cells from their nose. Investigators will use the blood sample to provide genetic information (specifically, presence or absence of alleles known to be associated with pulmonary fibrosis). Nose cells from individuals with the genetic markers that investigators are studying will be grown in the the lab to allow investigators to learn more about how the cells respond to various forms of environmental stress, such as exposure to cigarette smoke. The goal of this study is to understand how specific genes affect airway cell function.
The primary objective of this pilot study will be to examine the effects of consuming whole grains, differing in the degree of processing, on insulin sensitivity and other cardiometabolic risk factors. The overall aim will be to assess feasibility of the test diets and to generate preliminary data.
The purpose of the study is to examine the hypothesis test that probiotics will reduce the frequency of exacerbation in patients with COPD.
