This study takes place in multiple locations across the United States.

Are you an adult who has been diagnosed with idiopathic pulmonary fibrosis (IPF)? This study will examine whether adding N-acetylcysteine (NAC) to standard treatment improves key indicators of IPF, including symptoms, in people with the TOLLIP rs3750920 TT genotype who are living with the disease. You must be age 40 or older to participate in this study. This study takes place in multiple locations.

Is your newborn in the neonatal intensive care unit at St. Louis Children’s Hospital? This study aims to better understand breathing problems and blood flow through the heart in premature newborns to better detect conditions such as pulmonary hypertension. To participate in this study, your newborn must have been born prematurely between 24 and 29 weeks’ gestation and be a patient in the Neonatal Intensive Care Unit at St. Louis Children’s Hospital.

Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery? Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.

Are you an adult with sickle cell disease? This study aims to determine whether monthly exchange blood transfusions (removing blood and replacing it with transfused red blood cells) can improve health and prevent or reduce the number of pain crises. To participate in this study, you must be at least 18 years old, have sickle cell disease, and have not been on a chronic exchange transfusion program for at least 2 months. This study is located in Pittsburgh, Pennsylvania.

Do you have symptoms of a lung disease (such as long-term wet cough, bronchiectasis, or recurrent pneumonia) with no genetic diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) or primary immune deficiency (PID), two conditions that can have similar symptoms. Researchers will combine information from genetic testing, lung imaging, and lung function tests to diagnose and tell the difference between these two conditions. Participants in this study must be 5 to 45 years old and must have symptoms of a serious lung disease but no diagnosis. This study is taking place at multiple locations in the United States and in Canada, including the NIH Clinical Center in Bethesda, Maryland.
