Clinical Trials

Are you a healthy adult? In this clinical trial, researchers are trying to improve the quality of heart CT scans by using new methods to create the images. Researchers will take normal CT images of the heart and compare those images to super high-resolution images made with a super-computer. Healthy adults aged 18 years or older may be able to participate. The study is taking place at the NIH Clinical Center in Bethesda, Maryland.

The purpose of this project is to test sleep reactivity as an independent cause of Shift Work Disorder (SWD). The primary hypothesis is that those with high sleep reactivity will show persistent SWD symptoms after experimental reduction of circadian misalignment, which will then be mitigated with CBT.

Shift work increases the risk for diabetes possibly due to the adverse metabolic effects of circadian misalignment. As shift work is not foreseen to disappear, the development of individually-targeted therapies for metabolic health in these vulnerable shift workers is urgently needed. This research will determine whether our dietary intervention can mitigate the adverse metabolic effects of circadian misalignment, which may help in the design of evidence-based dietary interventions to improve the metabolic health in shift workers.
