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 purpose of this study is to perform renal artery denervation at the same time as atrial fibrillation ablation. RA denervation may reduce blood pressure, increase the chances of a successful atrial fibrillation ablation, and decrease the number of medications required to control blood pressure.
The purpose of this study is to assess patient satisfaction, the efficacy and compliance of granisetron patch versus ondansetron pills for radiation induced nausea and vomiting in malignant glioma patients receiving six weeks of radiation therapy (RT) and concomitant temozolomide (TMZ). Use of the patch may benefit brain tumor patients by increasing compliance. All eligible adult malignant glioma subjects should receive a planned total dose of 54-60 GY of radiation and 75 mg/m2 of daily TMZ for a total of six weeks. Subjects will be randomized to receive either granisetron patch or ondansetron for three weeks. Weeks 3-6, they will received the other medication. The granisetron transdermal delivery system (supplied as a 52 cm^2 patch containing 34.3 mg of granisetron - 3.1 mg/day) is applied once per week 24 hours before the weekly radiation and chemotherapy, while the ondansetron 8 mg oral tablet is taken once a day 30-60 minutes prior to each dose of chemotherapy. Subjects will fill out questionnaires regarding the effectiveness of the medication and their satisfaction, and which anti-emetic they prefer. Safety will be assessed throughout the six weeks of radiation by the clinical research nurse using the Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0. All subjects who receive both ondansetron and Granisetron Transdermal Delivery System (GTDS) treatment will be included in analyses of treatment preference. However, all other efficacy and safety analyses will include all subjects who received ondansetron or GTDS.
Laminin alpha-2 (LAMA2)-related muscular dystrophy (LAMA2-MD, Merosin Deficient CMD) is a form of congenital muscular dystrophy (CMD). A person with LAMA2-MD will have changes on brain imaging (MRI), a decrease or absence of the protein merosin (laminin 211) on muscle or skin biopsy and changes in the LAMA2 gene that are inherited from both parents. Several studies have described the changes on brain MRI. Brain changes on MRI do not correlate with the partial reduction or absence of merosin on muscle or skin biopsy. 8-30% of people with LAMA2-MD develop seizures. The types of seizures, electroencephalogram changes and common treatment regimens have not been characterized. This study will review the magnetic resonance imaging (MRI) changes, determine whether certain brain MRI changes are linked to seizures and define the common seizure treatment regimens.
Glucose-dependent Insulinotropic Polypeptide (GIP) and xenin-25 are peptide hormones produced/released from your intestines and help regulate blood sugar levels after you eat. We have previously performed studies in humans that measured the effects of xenin-25 and GIP (alone and together) on blood sugar levels. One study was conducted with an intravenous infusion of glucose but without ingestion of a meal. In this study, xenin-25 increased the effects of GIP on insulin secretion- but only in humans without type 2 diabetes mellitus (T2DM). A second study was conducted in conjunction with ingestion of a meal. In this study, xenin-25 reduced blood glucose levels by delaying gastric emptying and this effect was similar in humans with and without T2DM. A variety of studies that we have performed suggest that xenin-25 works by activating nerves. A specific nerve called the vagus nerve plays an important role in regulating insulin secretion. This study will determine if the vagus nerve (which was disrupted if you had a vagotomy) is needed for the effects of xenin-25 on insulin secretion and/or gastric emptying.
This is a phase 3, open-label, multiple-center, randomized cross-over study to assess the safety and efficacy of [123I]NAV5001 SPECT imaging in aiding in the differentiaion of parkinsonian syndromes from non-parkinsonian tremor.
The purpose of the study is to determine differences in levels of serum chemokines from patients undergoing treatment with Boceprevir. The aim is to determine if non-responders have significantly different levels of chemokines than responders.
This research study is to see if smartphone applications help college women remember to take birth control better than pharmacist consultation alone. Patients will participate in this study for 6 (six) months. The study will have two groups. Patients will be randomly assigned to one group or the other. The control group will be counseled by the pharmacist on the importance of taking birth control as prescribed. The study group will get the same counseling, but will also be set up to receive reminders to take medication on a smartphone application called Dosecast.
Diabetes is more likely to occur during pregnancy. When present only in pregnancy it is called gestational diabetes, and it places both mom and baby at risk for complications. Glyburide is one of the currently used treatments for diabetes during pregnancy. This drug is a medication taken by mouth that decreases sugar levels in the blood. It is known to decrease the risk of complications linked to diabetes in pregnancy. Recent studies in pregnancy have described a difference in the way and how well the drug works compared to when used outside of pregnancy. Oral blood sugar lowering agents are approved by the Food and Drug Administration (FDA) to lower blood sugar in non-pregnant subjects with diabetes. No oral (taken by mouth) blood-sugar lowering agents are FDA approved for use in pregnancy. Although Glyburide is not FDA approved for this use, it is the most commonly used oral blood sugar lowering agent in pregnancy. This research study will help us learn more about the variations in blood sugar levels in women with diabetes in pregnancy who are taking glyburide and how changes in the timing of when the glyburide is taken would affect blood glucose levels. The goals of this study are: - To find the how glucose changes throughout the day in women with diabetes in pregnancy receiving glyburide - To learn the effect of changing the time of taking glyburide on glucose levels - To learn the effect of changing the time between glyburide doses on glucose levels - To see if insulin is secreted the same throughout the day in response to a morning dose of glyburide.
Participation in music therapy will result in improvement in cognitive functioning, as measured by neuropsychological testing 9-12 months following surgery.
This is a pilot study to identify the degree of grey and white matter involvement in patients with Amyotrophic Lateral Sclerosis (ALS) utilizing non-invasive techniques. The imaging to be utilized will be the 7 Tesla (7T) magnetic resonance imaging (MRI) of the brain. These results will be correlated to the ALS Functional Rating Scale - Revised (ALSFRS-R) score to assess if any changes in MRI can be predictive in the disability of the ALS patients at baseline and at 6 month intervals. The participants will be asked to return every 6 months for a neurological examination, ALSFRS-R assessment, measurement of the vital capacity and MRI as outlined above to monitor progression of the disease.
