Filter by:The purpose of this week long study is to describe sleep and problems with sleep in women diagnosed with Fibromyalgia syndrome.
RATIONALE: Measuring levels of interleukin-6 and depression may help doctors understand the relationship between interleukin-6 and depression. It may also help the study of cancer in the future. PURPOSE: This clinical trial is studying depression and interleukin-6 production in patients with ovarian epithelial cancer.
The purpose of this study is to test whether shifts in the timing of the biological clock to a later hour (phase delay shifts of the human circadian system) can be produced in response to four successive evenings of light exposure, and whether that phase shift will result in greater evening alertness and greater nighttime sleep efficiency. Three different light sources will be compared: 1) standard fluorescent light; 2) blue-enriched light; 3) incandescent fluorescent light.
Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a good regulation of these circadian rhythms a uniform external synchronisation is necessary. This is the synchronisation of the biological clock of our body by light and other influences. In case of a disturbance of the external synchronisation, due to for example naps during the day or wake periods at night, internal rhythms can be unlinked. As a result a weakened melatonin rhythm and a problematic sleep-wake cycle can be observed. Most dialysis patients have sleep problems. Their sleep latency is prolonged. They often take a nap during the day and their sleep efficiency is poor. There has only been one study on the melatonin rhythm of dialysis patients. The conclusion of this study was that the melatonin rhythm of dialysis patients is weakened and disturbed, probably caused by renal insufficiency. In this study no link was made between melatonin rhythm and the nature and severity of possible sleep problems. In different studies with non-dialysis patients and a disturbed melatonin rhythm, exogenous melatonin at the right time leads to a recovery of the normal rhythm and the normal biological clock and a better quality of life. The aim is to research the endogenous melatonin rhythm and to improve sleep problems of hemodialysis patients with a placebo-controlled study with exogenous melatonin. Next to this a substudy is performed, in which the effect of the change of daytime to nocturnal in hospital hemodialysis on sleep and melatonin is researched.
RATIONALE: Yoga may help improve sleep, fatigue, and quality of life in cancer survivors. PURPOSE: This phase II trial is studying how well yoga works in treating sleep disturbance in cancer survivors.
Sleep disorders are prevalent health problems that reduce quality of life, increase risks for medical disease, and enhance healthcare costs/utilization. Only a small proportion of these cases are diagnosed in primary care. Pilot data from this VA suggest that sleep disorders are not adequately managed in a primary care setting: 33% of veterans with an insomnia complaint had an undiagnosed primary sleep disorder (e.g., sleep apnea), and 50% of these patients were prescribed pharmacologic treatment for insomnia by their primary care providers.

Jet lag and some sleep disorders are caused by a disruption in an individual's "internal clock." Understanding the most effective way to quickly re-adjust the body's internal clock will be beneficial for treating individuals with these conditions. This study will evaluate the combined effectiveness of light and non-light therapies at regulating sleep cycles and improving sleep quality.
To assess the effectiveness of Lunesta on cancer patients who have received chemotherapy and who require patient controlled analgesia (PCA), specifically to assess whether Lunesta will: - improve sleep thereby decreasing need for opiates via PCA - improve sleep thereby decreasing pain by self report - improve sleep thereby decreasing fatigue by self report
The primary objective of this study is to investigate the effects on RLS symptoms and sleep disturbance of pramipexole (Mirapexin) 0.125 mg/day to 0.75 mg/day per os for 12 weeks, compared to placebo, in the treatment of patients with idiopathic Restless Legs Syndrome
