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

Group-based Integrative Pain Management in Primary Care Safety Net Clinics
Recruiting
Socioeconomically disadvantaged populations have a high prevalence of chronic pain, exacerbated by social isolation, intersectional stigma, and disparities in pain assessment and treatment options. Effective interventions using a multilevel, biopsychosocial approach are needed to decrease the unequal burden of pain. The proposed study will test group-based integrative models of pain management in primary care safety net clinics to improve pain care for racially and ethnically diverse low-income... Read More

Recruiting
This is a long term follow-up study for chronic hepatitis B (CHB) subjects who have received imdusiran treatment in a prior clinical trial, stopped NA therapy during that trial, and remain off therapy. Subjects may enroll after completing the end of study visit (baseline visit within 12 weeks ± 1 week from the end of study \[EOS\] visit) from their imdusiran clinical trial (the "parent study"). No interventions will be performed in this study other than blood sample collections, review of curren... Read More

Determinants of Incident Stroke Cognitive Outcomes and Vascular Effects on RecoverY
Recruiting
The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke... Read More

Fermented Food-Supplemented Diet in Ulcerative Colitis
Recruiting
The purpose of this study is to see how a diet that supplements fermented foods effects inflammation and quality of life in patients with mild to moderate Ulcerative Colitis (UC). There is a paucity of research and an enormous need for better understanding of diet and intestinal inflammation. Fermented food have been shown to positively influence inflammatory cytokines and intestinal microbial diversity in healthy volunteers.

Melanoma Margins Trial-II: 1cm v 2cm Wide Surgical Excision Margins for AJCC Stage II Primary Cutaneous Melanoma
Recruiting
Patients with a primary invasive melanoma are recommended to undergo excision of the primary lesion with a wide margin. There is evidence that less radical margins of excision may be just as safe. This is a randomised controlled trial of 1 cm versus 2 cm margin of excision of the primary lesion for adult patients with stage II primary invasive cutaneous melanomas (AJCC 8th edition) to determine differences in disease-free survival. A reduction in margins is expected to improve patient quality of... Read More

The Role of Secondary Bile Acids in Intestinal Inflammation
Recruiting
The cause of Inflammatory bowel disease (IBD) is unknown, but intestinal bacteria-involved in the production of molecules that impact health-are widely accepted to play a key role. A significant proportion of IBD patients with pouches (surgically created rectums after the diseased colon is removed) continue to have inflammation similar to their previous disease.
Only a few microbes are known to have the capability to modify primary bile acids (PBAs) made by the liver to secondary bile acids (SB... 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.
