PURPOSE: Although many studies have investigated the clinical importance of sleep apnea on rapid eye movement (REM) and non-REM (NREM) sleep, the relationship between behavioral performance and apneic events during different sleep phases remains unclear. In the present study, we sought to investigate the effect of sleep phase fragmentation due to sleep-disordered breathing (SDB) during REM and NREM on the vigilance and sustainability of attention based on psychomotor vigilance task (PVT) performance...

Obstructive sleep apnea (OSA) is prevalent in obese subjects. Plasma adiponectin level in obese subjects is decreased. Whether reduced adiponectin level is associated with OSA is unknown. Participants without a previous diagnosis of OSA or who have not been treated with continuous positive airway pressure were enrolled and parameters of interest were collected. Polysomnography was performed to evaluate the presence of OSA and the severity of OSA as indexed by the apnea-hypopnea index (AHI). Between-group differences were analyzed...

PURPOSE: Obstructive sleep apnea (OSA), typically manifested as snoring, is closely associated with obesity. However, the directionality of associations of OSA with cardiometabolic risk markers is unclear, as obesity increases risk for OSA, and OSA results in excess weight gain and its metabolic consequences. Less is known about how obesity and OSA may relate in children and adolescents and whether maternal OSA may influence the development of obesity and cardiometabolic dysfunction in offspring...

STUDY OBJECTIVES: Although drug-induced sleep endoscopy (DISE) is an accepted method to localize upper airway obstruction, it is not known whether allsites identified by DISE must be treated to achieve sufficient apnea-hypopnea index (AHI) improvement. The aim of this study was to compare outcomes forunilevel (upper) versus multilevel DISE collapse patterns in a patient cohort that only underwent modern palatopharyngoplasty. Our hypothesis was that notall tongue base-level obstructions on DISE must be treated...

OBJECTIVE: The acoustic characteristics of voice are determined by the source of the sound and shape of the vocal tract. Various anatomical changes after uvulopalatal flap (UPF) operation can change nasalance and/or other voice characteristics. Our aim was to explore the possible effects of UPF creation on speech nasalance and the resonatory features of the final nasal consonants, and thus voice characteristics. METHODS: A total of 30 patients (26 males, 4 females) with obstructive sleep apnea who underwent UPF operation were recruited...

Importance: Sleep apnea (obstructive and central) is associated with adverse cardiovascular risk factors and increased risks of cardiovascular disease. Positive airway pressure (PAP) provides symptomatic relief, whether delivered continuously (CPAP) or as adaptive servo-ventilation (ASV), but the associations with cardiovascular outcomes and death are unclear. Objective: To assess the association of PAP vs control with cardiovascular events and death in patients with sleep apnea...

BACKGROUND: Right ventricular (RV) involvement in obstructive sleep apnea syndrome (OAS) is controversial. The aim of this study was to determine a correlation between echocardiographic parameters of RV function and severity of OSA assessed by the apnea- hypopnea index (AHI). METHODS: Sixty patients with suspected OSA were enrolled. All patients had overnight polygraphy and an echocardiographic assessment of RV structure and function. Patients were divided into three groups: a control group (n=20) with an AHI<5/h, a group of mild to moderate OSA (n=18) with an AHI=5-30/h and a group of severe OSA (n=22) with AHI≥30/h...

BACKGROUND: Obstructive sleep apnea (OSA) affects up to 26% of US adults, is often undiagnosed, and increases perioperative morbidity. We hypothesized that patients screened on the day of surgery as moderate/high risk for OSA (S-OSA) present similar perioperative respiratory complications, hospital use, and mortality than patients with previously diagnosed OSA (D-OSA). Second, we hypothesized that both OSA groups have more respiratory complications than No-OSA patients. METHODS: The electronic medical database from 1 academic and 2 community hospitals was retrospectively queried to identify adults undergoing nonemergent inpatient surgery (January 1, 2012, to December 31, 2014)...

Overlap syndrome of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) leads to increased morbidity and mortality. There have been no reports available on the overlap syndrome for Koreans. Our primary aim was to identify prevalence and predictors of the overlap syndrome in Koreans.This is a cross-sectional study with a community-based sample of 1298 participants (mean age, 59.7 ± 6.7) from the cohort of Korean Genomic and Epidemiologic Study during 2013 to 2014. OSA and COPD were assessed by apnea-hypopnea index (AHI) and the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC < 70%), respectively, based on polysomnography and spirometry measurements...
