Filter by:The use of energy from food changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the amount of energy that people who have a relative with type 2 diabetes (parent, sibling, or grandparent) use to perform their daily activities. This study is being done to test the hypothesis that the daily use of energy in people who have a history of type 2 diabetes in their family will be different after they have slept short hours for 16 days in comparison to when they have slept longer hours for 16 days.
The use of sugar and starch-like foods for energy (carbohydrate metabolism) changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the carbohydrate metabolism of people who have a relative with type 2 diabetes (parent, sibling, or grandparent). This study is being done to test the hypothesis that the carbohydrate metabolism of people who have a history of type 2 diabetes in their family will be different after they have slept short hours for 10 days in comparison to when they have slept longer hours for 10 days.
Background: Sleep curtailment is common and is associated with increased mortality due to cardiovascular causes. However, the mechanisms are not completely understood.We hypothesized that partial sleep deprivation caused however significant changes in sympathetic activity and endothelial function in healthy volunteers. Methods: Thirteen young healthy male volunteers will be monitored during 12 days by sleep diary and wrist actigraphy. The subjects will keep under their usual daily activities and randomized to 5 nights of prolonged sleep (control) or partial sleep deprivation, interposed by 2 nights of unrestricted sleep (wash out). At the end of each period, the subjects will be evaluate by: 1. electrocardiogram and beat-to-beat blood pressure with spectral analysis of heart rate and blood pressure in the supine position and after head up tilt test maneuver; 2. resting plasma norepinephrine; 3. venous endothelial function (dorsal hand vein technique).
The purpose of this study is to determine the effects of pregabalin on sleep problems in patients with seizures.
The purpose of this study is to monitor sleep in patients using breathing machines, because little is known about sleep when patients use masks to help their breathing. We'd like to compare sleep in patients using masks to that in patients with a tube in their throats.
This study evaluates the efficacy of sleep deprivation treatment in accelerating antidepressant responses when administered during the first week of medications and augmenting a sustained response with chronobiological interventions. Sleep deprivation and chronobiological augmentation may offer a rapid and sustained antidepressant response in mood disorder patients treated with medication, sleep deprivation, bright light therapy and sleep phase advance compared with medication only. The chronobiological treatment is rapid, non-invasive and has few side effects and could be of significant clinical benefit.
Older people living in nursing homes do not sleep very well for many reasons. Sleep disorders such as sleep apnea (when someone briefly stops breathing during sleep), and night time urination, along with the problems caused by the nighttime environment of the nursing home, such as noise and disruptive care routines can all contribute. Poor sleep can lead to other health problems or make existing health problems worse. This study will evaluate how well a sleep hygiene intervention and a medication for sleep (ramelteon (Rozerem)) work to improve sleep in nursing home residents with poor sleep. Ramelteon is FDA approved and has been tested in older adults living in the community, but not in older adults living in nursing homes. We expect sleep to improve on the study drug along with the sleep hygiene intervention, in comparison to placebo along with the sleep hygiene intervention. Based on adverse events reported in previous samples of older subjects, we expect the study drug to cause few side effects.
Young subjects and patients with nocturnal respiratory disorders are frequently involved in sleep-related accidents. This study assess the impact of chronic sleep restriction (4 hr of sleep during 5 days) or total sleep deprivation in young or mature healthy subjects or snorers on simulated driving, objective and subjective sleepiness and objective and subjective cognitive performances. The effects of recovery night on these parameters are also assessed.
Work requirements for medical trainees result in substantial sleep loss. Sleep loss has been associated with increased levels of certain inflammatory hormones that could have negative impact on blood vessel function. The purpose of this study is to determine the effects of sleep loss on blood hormone levels and blood vessel function in medical trainees.
A randomized controlled trial design will be used to answer whether a behavioral-educational sleep intervention and support from a nurse in the immediate postpartum improves maternal and infant sleep 6 weeks later.
