Do you or your child have a platelet, bleeding, or white blood cell disorder?
This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Are you a woman who is postmenopausal or a man older than 65? This study will investigate the effects of oral progesterone for older women and testosterone for older men on QT intervals. QT intervals that are increased by medicine can lead to dangerous heart rhythm problems. Researchers hope to learn more about why this happens and how to deliver safer doses. This study is located in Indianapolis, Indiana.

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 an adult with primary light chain amyloidosis? Researchers in this study are investigating new ways to look at the heart to identify when it is not working properly. You may be able to participate if you are at least 18 years old and have been diagnosed with primary light chain amyloidosis. This study is taking place in Boston, Massachusetts.

Are you an adult with polycythemia vera or thrombocytosis? This study aims to find a new treatment or cure for polycythemia vera and thrombocytosis by locating genes and their changes, or mutations, that may contribute to these disorders. To participate in this study, you must have polycythemia vera with elevated hemoglobin (higher than 18 in men and 16 in women) or thrombocytosis with an elevated platelet count (higher than 450,000). This study takes place in Salt Lake City, Utah.

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.
