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.
