Are you a 30- to 55-year-old smoker or non-smoker who would like to support better understanding of COPD risk factors? This study aims to find early signs of COPD in adults who have a high risk of this condition. Researchers will compare results from questionnaires, lung tests, and other tests in people who smoke and in people who do not smoke to look for factors that predict which people will develop COPD. To participate in this study, you must either currently smoke or have no history of smoking. This study takes place in multiple locations in the United States.

Have you or your child been diagnosed with cystic fibrosis, and would you like to support better diagnosis of lung infections? This study is exploring new ways to diagnose bacterial lung infections in people who have cystic fibrosis. The study will test whether analyzing a participant’s breath and sputum samples can help diagnose infections. Participants in this study must be at least 3 years old. This study is taking place in multiple locations in the United States.

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 24-27 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

This is an observational - data and specimen collection study. There have been increasing reports of vaping-induced lung injury, including severe lung injury and rare cases of death. The mechanism by which vaping contributes to lung injury in susceptible persons is unknown, as is impact on chronic lung disease. The investigators aim to identify individuals with chronic electronic nicotine delivery device (ENDD) exposure and matched controls within our ongoing cohort of HIV+ and HIV-uninfected individuals, collect PFT data, bank respiratory and stool samples and collect clinical data for studies of clinical risk, inflammation, biomarkers, and the microbiome in the identification and modification of risk of progression to lung injury or chronic pulmonary disease.

The purpose of this study is to non-invasively characterize the fibrotic consequences of single ventricle physiology, its possible solution and effect on lymphatics. This project investigates the response to acute imposition of Fontan hemodynamics by examining the interrelationship between liver and cardiac fibrosis/dysfunction and lymphatic congestion along with a pilot trial of the antifibrotic agent, spironolactone, to prevent these consequences and to determine if MRI can discern these differences. The combination of serum biomarkers and MRI form a powerful non-invasive tool in putting together this complicated web of dysfunction.

The Bashir™ Endovascular Catheter has been designed to administer therapeutic agents in the peripheral vasculature. Because of the unique design of the catheter, with its six expandable infusion limbs, the Bashir™ Endovascular Catheter has the ability to: 1. Create a much larger central channel for blood flow, thereby utilizing the body's own endogenous fibrinolytic agents to lyse the clot, and 2. Greatly enhance the radial dispersion of a catheter-administered thrombolytic agent throughout the thrombus. Expansion of the multiple arms of the basket in the infusion catheter causes fissuring of the clot. The net result is that a greater surface area of clot is exposed to both endogenous and exogenously administered lytic agents, thereby promoting clot dissolution.

22q11.2 deletion syndrome is a genetic disorder that can cause heart defects, facial abnormalities, and developmental and learning disabilities. The severity of the disorder can vary widely among people. This study will analyze DNA from people with 22q11.2 deletion syndrome to identify genetic variations that may affect the severity of the disorder.
