Filter by:This study intends to determine whether continuous positive airway pressure (CPAP) can reduce arterial stiffness (measured by pulse wave velocity) in nonsleepy as well as in sleepy patients with obstructive sleep apnea .
The primary objective of the Nuvigil/Provigil Pregnancy Registry is to characterize the pregnancy and fetal outcomes associated with Nuvigil and Provigil exposure during pregnancy.
Background: A recent systematic review showed that patients undergoing esophagectomy for cancer had scores of physical function, vitality and performance of health in general significantly lower than those obtained from the reference population. The analysis of the quality of life at six months follow-up showed that the total score and physical function were better before surgery and symptoms-based scales indicated that the fatigue, dyspnoea and diarrhea were worse six months after esophagectomy. The objective of this study is therefore to assess the impact of esophageal resections for cancer on the quality of life of patients and to improve it through simple interventions of post operative care. The study is divided into two steps. This is step 1. Patients will be randomized into four groups receiving respectively: psychological counseling for support plus appropriate measures to reduce sleep-wake rhythm disorders during ICU stay; psychological counseling alone; appropriate measures to reduce sleep-wake rhythm disorders during ICU stay alone; or standard care. The primary end point are the items SL (sleep disorder) and QL2 of the QLQ C30, and the secondary end point is the score of the PSQI.
The overall goal of the present application is to test the hypothesis that shift workers, who are chronically exposed to circadian misalignment and sleep loss, have a higher cardio-metabolic risk than day workers, and that the accumulated sleep debt and the degree of circadian misalignment both predict their elevated cardio-metabolic risk.
The goal of this research study is to learn if a type of light therapy can be used to help patients with advanced cancer who are having difficulty sleeping to sleep better.
The purpose of this research is to see the effects (good and bad) of Melatonin CR on sleep in 4-8 year old children with autism spectrum disorders and sleep problems.
RATIONALE: Following a program that uses written materials and pre-recorded mp3 devices may help improve the sleep of cancer survivors. It is not yet known which home-based program is more effective in improving the sleep of cancer survivors. PURPOSE: This randomized phase II trial is comparing two home-based programs for improving sleep in cancer survivors.
RATIONALE: Methadone hydrochloride may reduce chronic neuropathic pain in patients with cancer. PURPOSE: This phase I trial is studying the side effects and best dose of methadone hydrochloride as first-line therapy in treating patients with chronic neuropathic cancer pain.
This research project consists of a three part study with five embedded sub studies. The first study phase identifies "body rhythms" of sleepiness/wakefulness and of melatonin levels for each subject (including sub-study 1). The second study phase identifies the optimum dose and timing of melatonin for regulating each individual's 24-hour sleep/waking cycle (including sub-study 2). The third study phase introduces a new independent variable, light (including sub-studies 3 and 4). Sub-study 5 is an optional longitudinal study. Sub-study 1 looks at how keeping a regular sleep schedule affects the body's natural rhythm. Sub-study 2 looks at how individuals metabolize melatonin. Sub-study 3 tests how individuals' endogenous melatonin production responds to bright outdoor light and Sub-study 4 tests a previous finding that artificial bright light exposed daily behind the knee can regulate the body clock. Sub-study 5 is an optional longitudinal study, an extension of the first study stage, for subjects whose rhythms are not clearly free-running.
The purpose of this study is to learn more about abnormal body rhythms in blind boys and girls that keep them from falling asleep at bed-time or cause them difficulty staying alert during the day. The investigators hope to learn if there are any differences between the body rhythms of girls and boys. The investigators also want to investigate whether age or puberty have an effect on body rhythms.
