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 study will be a 6-month intervention that is examining how different dietary approached may be useful for women with Polycystic Ovarian Syndrome (PCOS) who are attempting pregnancy, particularly by measuring changes in weight. Participants will be randomly assigned to following one of two dietary approaches for weight loss: 1) a low-calorie approach to weight loss (reducing caloric intake by approximately 500 calories per day) or 2) a low-fat, low-glycemic index vegan diet. A vegan diet is one that does not contain any animal products (no meat, fish, poultry, eggs, or dairy) but emphasizes plant-based foods, such as fruits, vegetables, whole grains, and legumes/beans. In addition, this diet will be low-glycemic index, which means the consumer will be asked to favor foods that don't cause a quick rise in blood sugar (for example, favoring oatmeal over cornflakes for breakfast). Participants will receive counseling and supporting materials on the dietary approach the participants are assigned to follow. Both diets are safe and have shown to be effective ways to assist with achieving a healthy weight. The investigators hypothesize that both groups will see improvements in weight and fertility with possible greater improvements seen among participants in the vegan group.
The purpose of this study is to determine the conducting ability of distal extremity nerves after a supraclavicular brachial plexus nerve block (with local anesthetic) has been placed at a more proximal location in the upper extremity.
The primary objective of this study is to collect pilot data on the efficacy of D-serine, relative to placebo, as a cocaine dependence treatment. Secondary objectives include evaluating D-serine, relative to placebo, on: 1. safety in treating cocaine-dependent adults and 2. tolerability.
A significant number of all invasive breast cancers are hormone sensitive and may be candidates for treatment with hormonal therapy. This project will assess the ability and usefulness of imaging hormone-receptor status in breast cancer with positron emission tomography (PET) and 6α-[18F]fluoro-17β-estradiol (FES), an estrogen analogue in patients who are scheduled to be treated with hormonal therapy given in combination with a selective allosteric inhibitor of AKT protein kinase (MK2206) .
The purpose of this study is to determine whether RNS60 is effective in the treatment of RR-MS compared to interferon beta-1a.
This is a randomized, double blind, placebo controlled study in opioid dependent subjects. Subjects meeting entry criteria will be treated with multiple doses of B-BNX or B-Placebo, with non-responders rescued within 6 hours. Open treatment B-BNX will be administered as follow-up therapy. Clinical efficacy assessments include the clinical opioid withdrawal scale (COWS), subject-rated assessments, and a urine drug screen.
The purpose of this study is to determine the success rate of two treatments for infection after total hip replacement: single stage arthroplasty exchange (your surgeon will take out your original implants and replace them with a complete new set) compared to irrigation and debridement with modular exchange (your surgeon will clean your implants with a surgical solution and take out the plastic liner and replace it with a new one - the rest of your hip implants will stay in place). The goal is to see if one is better than the other for the treatment of hip infection after a total hip replacement. A successful treatment means that you did not have to have another surgery on your hip for an infection-related reason.
Acute changes in axial diffusivity will correlate with the severity of injury in patients that suffer an acute spinal cord injury.
Many missed and delayed cancer diagnoses result from breakdowns in communication and coordination of abnormal findings suspicious for cancer, which often first emerge in the primary care setting. Delays in the follow-up of abnormal test results persist despite the reliable delivery of test results through the electronic health record. This intervention is the final study in a three-phase project that will develop and test an innovative automated surveillance intervention to improve timely diagnosis and follow-up of five common cancers in primary care practice. The investigators hypothesize that the median time in days from diagnostic clue to follow-up action (e.g. time to colonoscopy examination after am abnormal colon-related test) will be significantly less in the intervention arm than in usual care. The investigators also hypothesize that the proportion of patients receiving appropriate and timely follow-up care will be significantly higher in the intervention arm than in usual care.
This study is being done to determine the difference between natalizumab therapy followed by two different withdrawal strategies using Glatiramer Acetate (GA) treatment paradigms in preventing clinical relapses and other markers of disease activity in patients diagnosed with Multiple Sclerosis (MS). We hypothesize that GA plus corticosteroids versus GA alone will prevent or reduce the re-occurrence of MS disease activity after discontinuation of natalizumab over a 12 month period. We further hypothesize that natalizumab therapy followed by GA treatment allows the reconstitution of the peripheral and CNS immune homeostasis. Primary objective: The primary endpoint will be the annualized relapse rate over the post randomization months as well as estimates of change over the natalizumab therapy period over the entire 12 months. Secondary objectives: To determine if and how long it takes for restoration of immune homeostasis under GA therapy following discontinuation of natalizumab.
