We postulated that three extremely obese Yucatan miniature pigs would have more sleep apnea than three nonobese Yucatan miniature pigs. Pigs were studied with the use of electroencephalograms, inductance plethysmography, oximetry, expired nasal CO2, or thermistors. All of the obese pigs, but none of the nonobese pigs, had both sleep apnea (8.5, 10.3, and 97.0 in obese pigs vs. O apnea + hypopne...

Clinical observation suggested that speech disorder seemed to be associated with sleep apnea. We recorded a standard speech sample from 39 matched subjects in three groups, 13 sleep apnea individuals, 13 subjects with COPD, and 13 subjects without sleep apnea or COPD. Three speech pathologists in a single blind listening task of the recorded samples judged whether or not speech disorder was pre...

Abstract Introduction For diagnosis and management of Obstructive Sleep Apnea (OSA), long-term multi-night monitoring is crucial. Convenient detection OSA at home required for this purpose. Using sound recorded by smartphone can provide a convenient way to detect OSA. In study, we present sound-based deep learning model that in real-time even environment where various noises exist. The trained ...

It has previously been reported that the duration of obstructive apneas increases from the beginning to the end of the night (M. Charbonneau, J. M. Marin, A. Olha, R. J. Kimoff, R. D. Levy, and M. Cosio. Chest 106: 1695-1701, 1994). The purpose of this study was to test the hypothesis that stimulation of upper airway (UA) sensory receptors during obstructed inspiratory efforts contributes to ar...

BACKGROUND AND PURPOSE Sleep apnea is a modifiable independent stroke risk factor and is associated with poor stroke outcomes. Mexican Americans have a higher incidence of stroke than non-Hispanic whites. In a biethnic community, we sought to determine the frequency of screening, testing, and treatment of sleep apnea among stroke survivors and to compare self-perceived risk of sleep apnea with ...

BACKGROUND Previous studies have suggested that the obstructive sleep apnea syndrome may be an important risk factor for stroke. It has not been determined, however, whether the syndrome is independently related to the risk of stroke or death from any cause after adjustment for other risk factors, including hypertension. METHODS In this observational cohort study, consecutive patients underwe...

Sleep apnea is a common chronic disease that is associated with coronary heart disease, stroke, heart failure and mortality, although the ability of sleep apnea treatment to reduce cardiovascular morbidity and mortality has not been demonstrated. In contrast to patients seeking treatment in sleep disorders centers, as many as half of individuals with moderate to severe sleep apnea in the genera...

OBJECTIVE Postoperative apnea is a major concern in infants undergoing surgery. In this study, we evaluated incidence and related factors for postoperative apnea in infants less than 60 weeks postconceptual age after herniorrhaphy. METHODS One-hundred fifty infants with post conceptional age (PCA) less than 60 weeks who underwent elective herniorrhaphy were studied over eight months in 2012. ...

OBJECTIVE Obstructive sleep apnea is common among patients with hypertrophic cardiomyopathy and may contribute to poor cardiovascular outcomes. However, obstructive sleep apnea is largely unrecognized in this population. We sought to identify the clinical predictors of obstructive sleep apnea among patients with hypertrophic cardiomyopathy. METHODS Consecutive patients with hypertrophic cardi...

The proportion of sleep apnea syndrome (SAS) in the general adult population that goes undiagnosed was estimated from a sample of 4,925 employed adults. Questionnaire data on doctor-diagnosed sleep apnea were followed up to ascertain the prevalence of diagnosed sleep apnea. In-laboratory polysomnography on a subset of 1,090 participants was used to estimate screen-detected sleep apnea. In this ...
