Are you an adult who has asthma, or are you willing to be a healthy volunteer? This study is looking at the DNA in airway cells to see how they differ between people who have asthma and people who do not. To get a sample of cells from your airways, you may have a bronchoscopy (a tube inserted through your mouth into your airways). To participate in this study, you must be between 18 and 70 years old, either with asthma or with no history of asthma. This study is located in San Francisco, California.

Do you have asthma and obesity and live near Aurora, Colorado? Obesity can lead to widespread inflammation that may make asthma worse. This study will test whether a medicine called CXA-10 reduces inflammation in the airways and body and improves asthma symptoms in people who have obesity. To participate in this study, you must be between 18 and 65 years old, have a BMI of 30 or greater, and have been on long-acting controller medicine—such as inhaled corticosteroids or long-acting beta2-agonists—for at least three months. This study is located in Aurora, Colorado.

Are you an adult with both asthma and obesity? This study is testing whether a medicine called L-citrulline can help treat asthma and improve lung function in people who have obesity. To participate in this study, you must be 18 to 65 years old and have asthma and obesity. This study takes place in Durham, North Carolina.

Has your child been treated for an asthma attack with an oral corticosteroid medicine in the last 12 months? A study team will recruit 60 teens and young adults (between 12 and 21 years old) with persistent asthma who are at high risk for future exacerbation. This study examines the contribution of interleukin 1 beta (IL-1β), a protein that is involved in the inflammatory response, in asthma flare-ups. This study takes place in Chapel Hill, North Carolina.

Do you have heart disease that requires an ICD to prevent sudden cardiac arrest? This study aims to learn what signs distinguish patients who have a higher risk of an arrhythmia that leads to sudden cardiac arrest. Researchers plan to track patients with a recent ICD replacement for 10 years. To participate in this study, you must be between 18 and 85 years old. This study is located in Washington, D.C.; Baltimore, Maryland; and Richmond, Virginia.

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

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.
