Active clinical trials for "Dyssomnias"

To determine sleep disturbance, pulmonary function test, 6 minute walk, echocardiogram abnormality, arterial blood gas, ventilation/perfusion scan of the chest in Scleroderma patient with Pulmonary Hypertension.

Sleep disturbances are of great relevance within the context of public health as they affect a sizable portion of the population with far reaching consequences. Many automobile and labor accidents as well as poor school and work performance can be traced to sleep disturbances, which are also linked to cardiovascular disease, metabolic syndrome, and psycho-cognitive alterations. OBJECTIVES: Establish the epidemiologic profile of sleep disturbances among the adult population of the city of Sao Paulo in 2007; Investigate associations between sleep patterns and disturbances in that population, taking into account the following variables: social-demographic status, anthropometrics, clinical, activity/rest cycle, eating and physical activity habits, mood disturbances, sexual dysfunction in males, alcoholism, drug addiction, genetic markers, biochemical, hematological, endocrine, immunologic and inflammatory indicators; assess the compatibility of the results collected in the current study with those of epidemiologic sleep investigations of said city carried out in 1987 and 1995 with the aim of determining the secular sleep disturbance trend. METHODS: The two-stage cluster randomized sample included 1100 individuals of the city of Sao Paulo, representing the population proportionally to gender, age groups and social classes. Data were amassed as follows: the application of home and institution questionnaires; description of the sleep patterns and disturbances through polysomnography and actigraphy, performed at the Sleep Institute; collection of peripheral blood for biochemical, hematologic, endocrine and genetic assays. STATISTICS: Subsequent to double typing (inputting) and analysis of data consistency, descriptive and analytical statistical assessments will be performed with the aim of describing patterns of sleep disturbances associated to the explanatory variables under investigation. In the light of bi-varied analysis, predictive/explanatory multivaried models were adjusted.

Obesity, caused by caloric intake over output, has become a global health problem. The relationship between sleep and obesity is widely discussed in the literature. Little is known regarding the compliance of sleep quality and patients' weight loss. This study aimed to review how sleep quality is affected by bariatric surgery, examine whether compliance with sleep quality can be predicted after bariatric surgery, and assess its correlation with excess weight loss.

The purpose of this research is to study pre-operative sleep problems and delirium in Hispanic/Latino patients after heart and lung surgery.

The purpose of this study is to determine whether sleep disturbances in children aged 7 to 12 during COVID-19 containment are more prevalent in children who received routine psychiatric care before containment compared to children who don't have any psychiatric care.

This study will help determine the relationship between impaired sleep and chronic kidney disease, specifically to determine if sleep disturbances are a risk factor for worsening kidney function.

The purpose of this week long study is to describe sleep and problems with sleep in women diagnosed with Fibromyalgia syndrome.

The purpose of this study is to quantify the degree of sleep disturbances after hip or knee replacement surgery. Through polysomnographic monitoring the disturbances in sleep stages will be clarified.

We wish to study sleep architecture in patients with chronic orthostatic intolerance. We will test the null hypothesis that there is no difference in time during the various phases of sleep between patients and healthy control subjects.

Several evidences in the literature suggest sleep interruption in critical care patients. Nowadays, the amount and the quality of sleep phases during the length of stay in the intensive care unit are largely unknown. In this study, the amount of time spent by the patients in N1, N2 N3 and REM phases during sleep is quantified.
