Percutaneous Intervention Versus Observational Trial of Arterial Ductus in Low Weight Infants
Recruiting
Patent Ductus Arteriosus is a developmental condition commonly observed among preterm infants. It is a condition where the opening between the two major blood vessels leading from the heart fail to close after birth. In the womb, the opening (ductus arteriosus) is the normal part of the circulatory system of the baby, but is expected to close at full term birth. If the opening is tiny, the condition can be self-limiting. If not, medications/surgery are options for treatment.

Impact of Immunosuppression Adjustment on COVID-19 Vaccination Response in Kidney Transplant Recipients
Recruiting
Immunocompromised individuals, such as solid organ transplant (SOT) recipients are at high risk of COVID-19 associated complications and mortality. Retrospective studies so far have shown that a majority of SOT recipients did not develop appreciable anti-spike antibody response after a first, second, or even third dose of mRNA vaccine. Treatment with antimetabolites was associated with poor vaccine response. The goal of this study is 1) examine whether transient immunosuppression reduction impro... Read More

International Consortium for Multimodality Phenotyping in Adults With Non-compaction
Recruiting
Non-compaction cardiomyopathy (NCCM) is a heterogeneous, poorly understood disorder characterized by a prominent inner layer of loose myocardial tissue, and associated with heart failure, stroke, severe rhythm irregularities and death. For a growing population diagnosed with NCCM there is a need for better risk stratification to appropriately allocate (or safely withhold) these impactful preventive measures. The goal of this international consortium is to improve care of patients with non-compac... 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.
