Active clinical trials for "Sleep Wake Disorders"

The purpose of this study is to determine whether listening to music before falling asleep can improve sleep quality in patients with sleep disorders.

Bronchial asthma is characterized by the presence of symptoms that vary over time and of severity. Asthma symptoms tend to worsen at night and in the early hours of the morning, and the presence of nocturnal symptoms is an important indicator of therapeutic intervention in order to control the severity of the disease. Aim of the study is to investigate sleep disorders and quality, as well as and depressive and anxiety symptoms in patients affected by severe asthma before and after 6 months of treatment with monoclonal therapy. An observational, cohort, prospective, monocentric study will be conducted to evaluate subjective quality of sleep at baseline and post monoclonal treatment.

The purpose of the study is to demonstrate that continuous apomorphine treatment during the night compared with placebo improves sleep quality in insomniac patient with Parkinson's disease.

This study will explore the long-term effects of exercise training on body composition, cardiorespiratory fitness, and energy metabolism in the community-dwelling elderly with sleep disturbances

Background Sleep disturbances are prevalent in hospitalized adult patients manifested as reduced sleep time and sleep efficiency as well as increased awakenings. Insomnia is the most frequent sleep disturbance. The effect of the change in sleep patterns in children prior to and after an elective surgery has not been evaluated objectively. Sleep in hospital may influence biological processes related to circadian rhythm. Melatonin is a hormone secreted by the pineal gland in a diurnal rhythm regulated by light- light suppresses melatonin secretion, while darkness enhances it. Melatonin has both chrono-biotic and sleep promoting properties. Exogenous administration of melatonin shortens sleep latency, increases sleep efficiency and total sleep time. Melatonin also improves disrupted circadian rhythm. Melatonin promotes sleep in a similar way to the natural sleep process, and maintains normal sleep architecture. Melatonin has a positive effect on children with sleep disturbances and is routinely administrated in pediatric sleep centers around the world for insomnia and a variety of sleep disorders. Side effects of melatonin are rare and scarce. Circadin is a slow released formulation of melatonin, which mimics night time secretion of natural melatonin. Children with sleep disorders who were treated with controlled release melatonin, demonstrated improvement in sleep latency and total sleep time. It is reasonable to assume that hospitalized children have disturbed sleep patterns prior to and following elective surgery. We hypothesize that melatonin will improve sleep patterns prior to and following surgery, by reducing sleep latency and extending total sleep time. We also hypothesize that this improvement will have positive impact on anesthetic stress measures and on recovery. The purposes of the study are: 1. To characterize sleep patterns in children undergoing surgery on the admission night prior to surgery; 2. To evaluate the effect of melatonin on sleep parameters on the night prior to surgery in children; 3. To evaluate the effect of melatonin on physiologic stress parameters during anesthesia and surgery in children; 4. To evaluate the effect of melatonin on sleep parameters of children postoperatively; 5. To evaluate the effect of melatonin on postoperative outcome measures in children. Patients, Methods. Ninety children (aged 4-18 years) will be evaluated. Sleep disorders will be screened by a pediatric sleep questionnaire. Sleep will be assessed by sleep logs and actigraphy for sleep onset time, sleep latency, total sleep time, total wake time, number and length of awakenings, sleep efficiency, sleep fragmentation index and sleep mean activity score. Recovery measures will include: length of hospitalization, infection rate, body temperature, cortisol levels, cooperation with medical staff. Study plan. The research will comprise of 5 consecutive steps. Step 1 will include the week prior to surgery and include sleep evaluation to all participants by sleep log and actigraphy. Step 2 is the night prior to surgery and will include sleep log and actigraphy. 30 children will receive melatonin (Circadin) 2mg, 30 children will receive placebo and 30 children will constitute the control group. Step 3 will be conducted during anesthesia and surgery where stress variables and need for anesthesia will be recorded. Step 4 will take place during post-operative hospitalization and will include actigraphy and sleep logs. Step 5 will take place at home two weeks after discharge and will include actigraphy and sleep logs.

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 .

Validation study of a novel sleep Device compared to a traditional sleep study.

This study aimed to verify the influence of night work and food intake during the night shift on the eating behavior of fixed night workers the next day.

The emerging Brazilian population is accompanied by the emergence of patients in an age group, including osteoarthritis. Osteoarthritis (OA) is one of the most prevalent musculoskeletal diseases, affecting 4% of the Brazilian population. By 2050, 30% of Brazil's population is over 60 years old. This has a higher degree of elderly with morbades as unbass on the association, such as osteoarthritis. Proper management of OA involves educational program, multidisciplinary team care and therapeutic maneuvers with weight loss and maintenance of mobility. Insomnia is the most frequent sleep disorder in the elderly and its execution almost always harms young women. Sleep quality is interfered with fatigue and pain exacerbation in people with OA, ie a sleep approach should be diagnosed in patients with comorbidity. In addition, chronic patients usually have insomnia and pressure in the use of opioids, sedatives and antidepressants, pointing to insomnia and mood swings for polypharmacy. To evaluate a quality of sleep as an intervention of the PARQVE 70+ Project. Prospective, case-control study. Patients over 70 years old treated at a geriatric outpatient clinic with eye or polyarticular osteoarthesis and clinical OA treatment indicator will be allocated and matched in two groups of 30 elderly. Patients underwent Pittsburgh Sleep Quality Index questionnaires and the Epworth Scale before the study began, 3 and 6 months after PARQVE interventions and number of analysts, and compared those who did not perform an intervention. The study aims to improve sleep quality, decrease pain, reduce quality and decrease daytime sleepiness in elderly with OA.

Sleep's deficiencies are very common in intensive care. Mechanical ventilation is a known factor in this deterioration.The investigators hypothesize that close-loop ventilation mode (Intellivent-ASV) is able to minimize sleep deterioration, adjusting ventilation to the patient needs.
