Reward Processing and Depressive Subtypes: Identifying Neural Biotypes
Recruiting
Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception... Read More

Using Electrophysiology to Index Non-invasive Brain Stimulation Effects on Reward System Functioning in Depression
Recruiting
Depression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.

Addressing Taste Dysfunction With Miraculin in Head and Neck Cancer Patients Receiving Radiation Therapy
Recruiting
Patients diagnosed with head and neck cancer who receive radiation therapy with and without chemotherapy develop altered sense of taste due to treatment effect, which typically arises in the second week of radiation therapy and progresses throughout the course of treatment. While some symptoms such as pain, mucositis, and xerostomia can be managed with pain medications and saliva replacements, taste alteration has an earlier onset and is a more difficult symptom to readily address and intervene...

Impact of Direct Current Electrical Stimulation on Treatment of Lumbosacral Radiculopathy
Recruiting
This study will compare two methods of electrical stimulation (alternating current and direct current) as an adjunctive therapy to treating lumbosacral radiculopathy. Both types of electrical stimulation have been used in clinical practice for physical therapy, however direct current stimulation is much less common and there is less known about its impact on physical therapy outcomes. The aim of this project is to show the efficacy of a novel device, the Neubie direct current device, compared to... Read More

Cortisol and Food Insecurity
Recruiting
This study will use a within-subjects design in a sample of individuals with a range of food insecurity recruited from the Los Angeles community (N = 400; 50% men). These participants will then, in counterbalanced order, be exposed to a gold-standard laboratory stressor and a control condition, one month apart. Moderation analyses will test whether cortisol reactivity to the stressor acts as a modulator of the relationship between high levels of food insecurity and increased hyperpalatable food... 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. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.
