Immunologic Response to Pneumococcal Polysaccharide Vaccine in Splenic Injury Patients
Recruiting
Persons without a spleen are susceptible to potentially lethal infections from certain bacteria, with pneumococcus being the most prevalent. Vaccines are provided to help protect against these infections, though they do not so with certainty. Trauma patients who sustain an injury to their spleen currently have three treatment options available for the treating surgeon - nonoperative management, embolization, or removal of the spleen. The purpose of this study is to investigate the antibody respo... Read More

Treatment of Systemic Lupus Erythematosus (SLE) With N-acetylcysteine
Recruiting
Systemic lupus erythematosus (SLE) is a chronic inflammatory disease which often has debilitating and potentially life-threatening consequences. The cause of SLE is unknown and current therapies lack specificity and carry significant side-effects. We previously discovered the depletion of glutathione in lymphocytes of patients with SLE and associated this metabolic change with the elevation of the mitochondrial transmembrane potential.
This study will titrate to tolerance during an initial 3 mo... Read More

Blood Changes After Exercise in Restless Legs Syndrome
Recruiting
The goal of this clinical trial is to learn how exercise changes molecules in the blood in people with restless legs syndrome (RLS) to better understand the cause(s) of RLS. The main questions the investigators aim to answer are:
How does long-term exercise change proteins in the blood?
How does a single exercise session change proteins in the blood?
The investigators will compare long-term exercise to no exercise to see if the changes in proteins are specific to exercise.
Participants will... 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.
