  • Start Times and Restful Sleep

    Sorry, not yet accepting patients

    The purpose of this study is to evaluate the efficacy of later school start times in increasing student sleep, and examine the association between later start times and physical activity, screen time, and commute time. Subjects will wear a FitBit activity tracker wristband for two separate 3-month periods (the year before and the year after the Francis Parker High School start time change in the Fall of 2020) and be advised to wear it as much as possible, especially while sleeping or performing physical activity. At the beginning and end of each study period (at 4 occasions), subjects will fill out a few short, non-invasive surveys about their commute, after-school activities, sleepiness, and preferences for morning or evening, and perform the non-invasive psychomotor vigilance test to measure alertness.

  • The Impact of Ramelteon on Sleep and Delirium in Patients Who Undergo Pulmonary Thromboendarterectomy (PTE) Surgery

    Sorry, in progress, not accepting new patients

    Sleep deprivation is known to affect brain function but is often ignored in the sickest patients including those in the intensive care unit after major surgery. In these patients, the levels of melatonin can also be altered. Melatonin is a hormone secreted in the brain that maintains the body's sleep-wake, or circadian, cycle. The investigators want to test whether improving sleep quality affects the risk of developing confusion (delirium) in patients having clot removed from their lung (open heart surgery). In order to improve sleep quality, the investigators will conduct a study of Ramelteon, a medication that mimics the activity of melatonin and measure its effects on levels of melatonin and monitor sleep.
