DBT Skills Groups for Veterans at High Risk for Suicide Attempt
Recruiting
Veteran suicide death is a national crisis. Risk factors include emotion dysregulation, which occurs across mental health disorders. Dialectical behavior therapy (DBT) is an evidence-based suicide intervention that targets emotion dysregulation but is resource-intensive and not widely available at VHA. A more efficient evidence-based DBT Skills Group (DBT-SG) is associated with reduced suicidal ideation and emotion dysregulation and likely more feasible to implement at VHA. This is a randomized...

Endotype-Targeted Therapy to Rescue OSA Patients Struggling with CPAP Adherence (TOP-CPAP)
Recruiting
More than 10% of the US population have obstructive sleep apnea (OSA). Standard of care is therapy with CPAP (continuous positive airway pressure) which virtually eliminates OSA. However, most patients use CPAP only for part of the night (4-5hours) and about 50% patients discontinue CPAP long-term. Alternative therapies are limited, thus many OSA patients remain at risk of OSA sequelae (e.g. sleepiness, memory issues, high blood pressure, etc.). Importantly, different patients get OSA for differ... 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.
