Do you have heart disease that requires an ICD to prevent sudden cardiac arrest? This study aims to learn what signs distinguish patients who have a higher risk of an arrhythmia that leads to sudden cardiac arrest. Researchers plan to track patients with a recent ICD replacement for 10 years. To participate in this study, you must be between 18 and 85 years old. This study is located in Washington, D.C.; Baltimore, Maryland; and Richmond, Virginia.

The study is to investigate that the worsening orthostatic tachycardia and symptoms after glucose ingestion in POTS patients are due to a greater increase in splanchnic venous capacitance and excessive blood pooling during an orthostatic challenge.

Are you a healthy adult between 40 and 90 years old and willing to help research? This study will test whether a new device called the OsciPulse system, which is designed to repeatedly compress a person’s legs, can improve blood flow through the legs to prevent or treat varicose veins. To participate in this study, you must be 40 to 90 years old and healthy. This study takes place in Philadelphia, Pennsylvania.

Ventilated pediatric patients are frequently over-sedated and the majority suffer from delirium, a form of acute brain dysfunction that is an independent predictor of increased risk of dying, length of stay, and costs. Universally prescribed sedative medications-the GABA-ergic benzodiazepines-worsen this brain organ dysfunction and independently prolong duration of ventilation and ICU stay, and the available alternative sedation regimen using dexmedetomidine, an alpha-2 agonist, has been shown to be superior to benzodiazepines in adults, and may mechanistically impact outcomes through positive effects on innate immunity, bacterial clearance, apoptosis, cognition and delirium. The mini-MENDS trial will compare dexmedetomidine and midazolam, and determine the best sedative medication to reduce delirium and improve duration of ventilation, and functional, psychiatric, and cognitive recovery in our most vulnerable patients-survivors of pediatric critical illness.

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.

Are you or a loved one on a ventilator in the hospital in Minnesota? This study is finding out whether people who are on a ventilator sleep better and have less anxiety if they can control their own sedation medicine. To participate in this study, you must be at least 18 years old and receiving mechanical ventilation while hospitalized. This study is located in Minneapolis and Rochester, Minnesota.

Is your child on a ventilator at Children’s Hospital Los Angeles? Ventilators can sometimes weaken the muscles around the lungs, especially in children. This study is testing whether a new computer method to control ventilators can help prevent muscle weakness in children. To participate in this study, your child must be between 1 month and 18 years old and have been on a ventilator for less than 48 hours (or 72 if they were transferred from another hospital) because of a serious lung disease. This study is located in Los Angeles, California.
