OBJECTIVE Our aim in the present study was to elucidate how type 1 diabetes mellitus (T1DM) and sleep parameters interact, which was rarely evaluated up to the moment. MATERIALS AND METHODS Eighteen T1DM subjects without chronic complications, and 9 control subjects, matched for age and BMI, were studied. The following instruments used to evaluate sleep: the Epworth Sleepiness Scale, sleep di...

= Abstract = Computerized sleep staging is maintained to be a possible replacement for human scoring of sleep and is expected to reduce substantially the sleep technologists7 time and efforts in scoring sleep into stages and practically to provide paperless polysomnography. So far various computer algorithms have been developed and automatic sleep analyzing systems have been tested mainly on no...

Snoring sounds generated by different vibrators of the upper airway may be useful indicators of obstruction sites in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). This study aimed to investigate associations between snoring sounds, obstruction sites, and surgical responses (≥50% reduction in the apnea-hypopnea index [AHI] and <10 events/hour) in patients with OSAHS. This pros...

Our visual system is plastic and adaptive in response to the stimuli and environments we experience. Although visual adaptation and plasticity have been extensively studied while participants are awake, little is known about what happens while they are asleep. It has been documented that sleep structure as measured by sleep stages using polysomnography is altered specifically in the first sleep...

BACKGROUND The identification of obstructive and central hypopneas is considered challenging in clinical practice. Presently, obstructive and central hypopneas are usually not differentiated or scores lack reliability due to the technical limitations of standard polysomnography. Esophageal pressure measurement is the gold-standard for identifying these events but its invasiveness deters its usa...

STUDY OBJECTIVES To measure the accuracy and reliability of a portable home oximetry monitor with an automated analysis for the diagnosis of obstructive sleep apnea (OSA) in children. DESIGN Prospective cohort study. SETTING Alberta Lung Association Sleep Center, Alberta Children's Hospital Sleep Clinic. STUDY SUBJECTS Consecutive, otherwise healthy children, aged 4 to 18 years, presentin...

Trazodone is prescribed widely as a sleep aid, although it is indicated for depression, not insomnia. Its daytime cognitive and psychomotor effects have not been investigated systematically in insomniacs. The primary goal of this study was to quantify, in primary insomniacs, the hypnotic efficacy of trazodone and subsequent daytime impairments. Sixteen primary insomniacs (mean age 44 years) par...

Autotitrating continuous positive airway pressure (CPAP) devices automatically adjust the pressure according to upper airway obstructions. The aim of this study was to compare the treatment effects of different automatic CPAP devices (AutoSet, Horizon and Virtuoso) with conventional CPAP in patients with obstructive sleep apnoea independently of financial manufacturer support. Twelve male patie...

OBJECTIVES/HYPOTHESIS To quantify trends and characteristics of sleep studies performed for Medicare beneficiaries in the United States. STUDY DESIGN Retrospective longitudinal study of the Centers for Medicare and Medicaid Services' Part B National Summary Data and Medicare Provider Utilization and Payment Data from 2000 to 2014. METHODS Sleep study data were analyzed according to type of ...

Sleep Disordered Breathing (SDB) is a group of diseases that affect the normal respiratory function during sleep, from primary snoring to obstructive sleep apnea (OSA) being the most severe. SDB can be detected using a complex and expensive exam called polysomnography. This exam monitors the sleep of a person during the night by measuring 21 different signals from an Electrocardiogram to Nasal ...
