The purpose of this study was to examine the effects of one night of continuous positive airway pressure (CPAP) therapy on oxidative stress (lipid peroxidation) levels and the antioxidant activities of superoxide dismutase (SOD) in hypertensive patients with severe obstructive sleep apnea (OSA)...

Conflicting data have been reported regarding the effects of Ramadan fasting on the circadian pattern of sleep and other physiological parameters. However, most data suggested a delay of circadian rhythm during Ramadan...

The purpose of this study was to examine the effects of one night of continuous positive airway pressure (CPAP) therapy on oxidative stress (lipid peroxidation) levels and the antioxidant activities of superoxide dismutase (SOD) in hypertensive patients with severe obstructive sleep apnea (OSA)...

Based on our practice, cardiac arrhythmias appear to be common among patients with obstructive sleep apnea (OSA), although the true prevalence of cardiac arrhythmias remains to be determined. It may influence morbidity, mortality and quality of life for patients with OSA...

Obesity hypoventilation syndrome (OHS) is one of the sleep disordered breathing (SDB) that is confused with obstructive sleep apnea (OSA) since most patients with OHS display repeated upper airway obstruction during sleep. Despite its major impact on health, this disorder is under-recognized and underdiagnosed...

Experimental fasting has been shown to alter the sleep-wakefulness pattern in various species. Since fasting during Ramadan is distinct from experimental fasting, the physiological and behavioral changes occurring during Ramadan fasting may differ from those occurring during experimental fasting...

Studies have suggested that ethnicity and environment may influence thyroid disease. We aim in this study to determine the prevalence of thyroid disease among Saudi (Arab) patients with laboratory-diagnosed obstructive sleep apnea (OSA) and the characteristics and predictors of thyroid disease associated with OSA...

Muslims have five obligatory prayers per day. The first prayer (Fajr) is at dawn (about 1 hour before sunrise); so, Muslims are obliged to wake up early on weekdays and weekends. Summer nights have earlier dawn and shorter nights; so, some Muslims wake up to pray Fajr and then sleep until work time (split-sleep), while...

Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness associated with sudden loss of muscle tone (cataplexy). Sodium oxybate (Xyrem® ) is a recently approved drug for the treatment of refractory cataplexy and excessive daytime sleepiness in patients with narcolepsy...

The BodyMedia’s SenseWear™ Armband (BSA) is a portable device that measures skin temperature, galvanic skin response, heat flux, and body acceleration (accelerometry). Accelerometry is measured using a two-axis micro-electronic mechanical sensor and the device has a built-in algorithm that can identify sleep and...
