PV Loop & Coarctation Study
Recruiting
Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.

Effect of Daily Mixed Spice Consumption on Memory Function
Recruiting
The aging process entails a multitude of structural and functional alterations within the brain, culminating in a gradual and progressive decline in cognitive function. Recent research has indicated that various spices may hold the key to enhancing brain health and combating the effects of aging on cognitive abilities. The hypothesis is that a mixture of spices, acknowledged for their reported memory protection potential, may yield a more potent beneficial effect on memory function than a single... Read More

Benefits of Choir for Older Adults with Unaddressed Hearing Loss (WP2)
Recruiting
Unaddressed age-related hearing loss is highly prevalent among older adults, typified by negative consequences for speech-in-noise perception and psychosocial wellbeing. There is promising evidence that group singing may enhance speech-in-noise perception and psychosocial wellbeing. However, there is a lack of robust evidence, primarily due to the literature being based on small sample sizes, single site studies, and a lack of randomized controlled trials. Hence, to address these concerns, this... 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.
