Do you have COPD, or are you a healthy volunteer who is willing to do an imaging test? This study will use an imaging test called single-photon emission computed tomography (SPECT) to compare the lung function of patients who have COPD with healthy volunteers who smoke and who do not smoke. The CT scan can detect death of cells in a process called apoptosis, which is linked to severe COPD and cannot be seen in the normal adult lung. To participate in this study, you must be at least 18 years old and either have moderate to severe COPD, not have COPD and be a smoker for longer than 10 years, or not have COPD and never smoked. This study is located in New York, New York.

Do you have asthma, COPD, or asthma COPD overlap syndrome? This study will look at whether a health coach can help people who have asthma, COPD, or asthma-COPD overlap syndrome with their condition. You will be randomly selected to meet with either a lung specialist alone or a lung specialist and a health coach, who will give you recommendations to improve your care and better manage your condition. To participate in this study, you must be age 18 or older, have asthma or COPD, and not already be seeing a lung specialist. You also must get your care from one of 10 health centers in San Francisco, California. This study is located in San Francisco, California.

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.

Does your child have higher triglyceride levels but normal cholesterol levels? This study is testing whether a protein supplement called carnitine can help prevent blood vessel stiffness in teenagers who have metabolic syndrome or other risk factors for heart and blood vessel diseases. Participants in this study must be between 13 and 19 years old and have moderate to high blood triglyceride levels but normal blood cholesterol levels. This study takes place in Houston, Texas.
