High Dose Aflibercept in Diabetic Macular Edema in Patients With Previous Vitrectomy
Recruiting
Patients with diabetic macular edema (DME) sometimes must undergo vitrectomy surgery (PPV) for diabetic and non-diabetic related issues. Patients may have improved DME with anti-VEGF therapy and ranibizumab has been found to reduce central macular thickness (CMT) with anti-VEGF therapy following vitrectomy. Those patients still require intravitreal injections but the pharmacokinetics of a vitrectomized eye are different than those eyes that have not undergone vitrectomy. The clearance of protein...

The Influence of Chardonnay Marc Intake on Gut and Cardiometabolic Health
Recruiting
Recently a dietary recommendation of 400 - 600 mg/ day has been proposed for the reduced risk of developing cardiovascular disease. Dietary flavanols can be obtained from the intake of foods such as tea, cocoa, wine, berries and apples. Incorporating Chardonnay Marc (the skins and seeds of Chardonnay grapes) into the diet can be an additional source of dietary flavanols. Like other flavanol-rich foods, Chardonnay Marc provides fiber and polysaccharides that may benefit gut health. This study see... Read More

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.
