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. This study is located in St. Louis, Missouri.

Have you been diagnosed with high blood pressure while pregnant? This study is investigating whether a mother’s blood pressure during pregnancy affects her newborn’s lung development. To participate in this study, your newborn must have been born either prematurely at more than 25 weeks’ gestation or at full term to a healthy mother or a mother who was diagnosed with high blood pressure during pregnancy. This study is located in Indianapolis, Indiana.

Is your newborn in the NICU at Holtz Children’s Hospital in Miami? Newborns born very prematurely often need oxygen therapy or ventilation to help them breathe and survive. This study will help doctors understand how changes in oxygen and carbon dioxide levels while newborns are getting treatment affect how their lungs develop. While your newborn is in the newborn neonatal intensive care unit (NICU), researchers will record his or her oxygen and carbon dioxide levels, heart rate, and other measures. To participate in this study, your newborn must have been born prematurely between 23 and 28 weeks’ gestation, be less than 28 days old, and be receiving oxygen therapy. This study is located in Miami, Florida.

The investigators propose to study the relationship between right ventricle (RV) steatosis and RV function, exercise capacity, and outcomes in humans with pulmonary arterial hypertension (PAH) and to identify potential drivers of lipid accumulation.

The Investigators propose a randomized trial of smart texts versus usual care for 6 months. The Investigators will randomize 100 PAH patients to the mHealth intervention or usual care. The Investigators will test the effect of a text-based mHealth intervention on HRQOL in PAH using the PAH-specific emPHasis-10 questionnaire. The Investigators will also test the effect of an mHealth intervention on exercise capacity, measured by a supervised home-based 6MWD test. Finally, the Investigators will examine the effect of the intervention on time to clinical worsening (composite of PAH therapy escalation, PAH hospitalization, and death) one year after randomization.

Do you have high blood pressure? In this clinical trial, researchers are studying different ways to improve home blood pressure monitoring. You may be able to participate if you are between 18 and 85 years old and diagnosed with high blood pressure. Participants will work closely with clinicians or other healthcare providers to schedule appointments, coordinate care, measure blood pressure, answer your questions, and treat your high blood pressure. The study is taking place in Rochester, New York.
