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 primary objective of this study is to characterize coronary artery blockages as determined by the LipiScan combined NIRS-IVUS catheter using multi-vessel imaging.
The purpose of this research study is to collect lung tissue and fluid from two groups of people: those who have severe asthma, and those who do not. These samples will then be tested in a laboratory to identify differences in the lung tissue cells and fluids that may exist between these two groups of people.
Historically, transthoracic Doppler echocardiography has been unable to provide interpretable data of blood flow within the lung parenchyma because of air attenuation of Doppler signals. Recently, a transthoracic Doppler system known as the Sonara/tek Transcranial Doppler (TCD) System has been developed that can identify parenchymal pulmonary blood flow (PPBF) signals. The ability to non-invasively collect information regarding the pulmonary aspect of the cardio-pulmonary system may provide valuable information and new insights into the structural and functional characteristics of the lung parenchyma and vasculature in health and disease states.
1. (Primary) To compare the effectiveness of a patient guided choice of care using a patient decision support tool to clinical guided care within a novel care process for non-specific low back pain. (We hypothesize that the patient guided choice model will demonstrate significant improvements when compared to the clinician guided care approach) 2. (Secondary) To qualitatively investigate which components of the patient choice educational methods were most effective for informed decision making among patients who participate in the patient guided choice of care approach (We hypothesize that dialogue method of patient guided choice will be identified as most useful)
The purpose of this study is to see if MR-guided laser ablation can effectively treat prostate tumor recurrences.
Establish normative data of ElMindA's Brain Network Activation (BNA) using evoked response in three age groups.
This phase I trial studies the side effects of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in patients with advanced breast or pancreatic cancer with metastases to the liver or lung. Diagnostic procedures, such as DCE-MRI, may help measure a patient's response to treatment
The purpose of this study is to examine the role of progesterone (a hormone found in both men and women) on stopping cocaine use. The study will examine whether the medication, in combination with behavior therapy will decrease cocaine use, cigarette smoking, withdrawal symptoms, impulsivity and stress.
The purpose of the study is to evaluate the effect of sitagliptin on overall blood glucose concentrations in Type I Diabetic subjects. The study also aims to evaluate post meal glucagon concentrations in Type I Diabetic subjects (a possible mechanism of reduced blood glucose concentrations) and indices of oxidation stress in the plasma of these subjects.
Hormone responsive breast cancer is common and costly. Long-term adjuvant endocrine therapy (AET) improves breast cancer outcomes greatly, but, unfortunately, is commonly associated with physical and emotional concerns. I propose to evaluate the feasibility and preliminary effectiveness of a behavioral intervention to facilitate problem identification, provide education, coaching for breast cancer survivors with symptoms while on AET. Therefore, the intervention intends to empower women to engage in better self-care and seek out resources they need, which, in turn, will lead to better symptom management.
