background sleep apnea (sa) is a common sleep disorder among us adults. associations of sa with alcohol consumption and some chronic diseases have been inconsistent. objectives this study aimed to estimate prevalence of sa and examine its associations with potential factors including alcohol consumption, asthma, diabetes, and hypertension. patients and methods this was a cross-sectional study o...

Although sleep disorders such as insomnia and obstructive sleep apnea are common in both children and adults, the clinical features and treatments for these conditions differ considerably between these two populations. Whereas an adult with obstructive sleep apnea typically presents with a history of obesity, snoring, and prominent daytime somnolence, a child with the condition is more likely t...

BACKGROUND AND OBJECTIVES Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ...

OBJECTIVE Obstructive sleep apnea syndrome is characterized by repetitive obstruction of the upper airways, and it is a risk factor for cardiovascular diseases. There have been several studies demonstrating low levels of nitric oxide in patients with obstructive sleep apnea syndrome compared with healthy controls. In this study, we hypothesized that reduced nitric oxide levels would result in h...

Obstructive sleep apnea is the result of repeated episodes of upper airway obstruction during sleep. Recent evidence indicates that alterations in upper airway anatomy and disturbances in neuromuscular control both play a role in the pathogenesis of obstructive sleep apnea. We hypothesized that subjects without sleep apnea are more capable of mounting vigorous neuromuscular responses to upper a...

BACKGROUND Irritable bowel syndrome (IBS) is assumed as one of the most frequent gastrointestinal disorders, which decreases the patient's quality of life. IBS pathogenesis, however, is not clearly defined. It seems that sleep apnea induces or escalates IBS clinical symptoms. This study aims at evaluating of IBS prevalence in patients, who are afflicted or are not afflicted with sleep apnea. ...

BACKGROUND AND PURPOSE Epidemiological studies have suggested a pathophysiological link between sleep apnea syndrome and cerebrovascular diseases. The mechanism by which sleep disturbance can affect the predisposition to developing stroke is not clear. The aim of this study was to investigate whether patients with obstructive sleep apnea syndrome have an increase in atherosclerosis indicators a...

background: as sleep has a critical role in health and social function and also, changes in women's sleep patterns can be the first indicator of mood disorders this study was conducted to investigate the sleep disorders among women with premenstrual dysphoric disorder. methods: in this study, using standard tools of general sleep questionnaire (gsq) and berlin questionnaire, sleep disorders amo...

BACKGROUND Obstructive sleep apnea is a common sleep disorder in stroke patients. Obstructive sleep apnea is associated with stroke severity and poor functional outcome. Continuous positive airway pressure seems to improve functional recovery in stroke rehabilitation. To date, the effect of continuous positive airway pressure on cognitive functioning in stroke patients is not well established. ...

Sleep apnea is a prevalent disorder associated with an increased risk of cardiovascular disease (CVD). While arterial stiffness is a surrogate marker for the development of CVD, the cardio-ankle vascular index (CAVI) is a recently developed metric for evaluating arterial stiffness. Clinical studies have shown that the CAVI is higher in patients with the sleep apnea syndrome. In particular, a re...
