NCT01807897
The purpose of this study is to compare three treatment modalities for central, or mixed obstructive and central, sleep apnea in patients with chronic heart failure and reduced ejection fraction. The modalities to be tested are nocturnal supplemental oxygen (NSO) and continuous positive airway pressure (CPAP). The main outcome measures will be left ventricular ejection fraction on echocardiogram and peak oxygen consumption on cardiopulmonary exercise testing.
NCT04941443
Pain has been recognized to be the most common and predictable side effect of medication abortion, causing significant distress associated with the process. Yet there is little known about the appropriate management of pain during this process, with no current evidence based recommendations for optimal analgesic regimens during the first trimester. The goal of this study is to evaluate the efficacy of oral methadone for pain control during medication abortion. The current medication regimen used to perform medication abortion is a dose of mifepristone (antiprogesterone) orally, followed by a dose of misoprostol (prostaglandin analogue) 24 to 72 hours later. Patients are prescribed a standard dose of ibuprofen 600-800mg tabs for pain control during the process. The investigators will conduct a non-randomized, pilot study with 25 patients evaluated at the Boston Medical Center family planning clinic at 10 weeks of gestation or less for medication abortion.
