BACKGROUND The classification of obstructive sleep apnea is on the basis of sleep study criteria that may not adequately capture disease heterogeneity. Improved phenotyping may improve prognosis prediction and help select therapeutic strategies. OBJECTIVES This study used cluster analysis to investigate the clinical clusters of obstructive sleep apnea. METHODS An ascending hierarchical clus...

UNLABELLED Obstructive sleep apnea (OSA) has high prevalence and may cause serious comorbidities. The aim of this trial was to show if simple noninvasive methods such as gag reflex and palatal reflex are prospective multivariate assessments of predictor variables for OSA. METHOD We evaluate gag reflex and palatal reflex, of fifty-five adult patients, and their subsequent overnight polysomnogr...

Obesity is a primary risk factor for the development of obstructive sleep apnea in humans, but the impact of obesity on central sleep apnea is less clear. Given the comorbidities associated with obesity in humans, we developed techniques for long-term recording of diaphragmatic EMG activity and polysomnography in obese mice to assess breathing patterns during sleep and to determine the effect o...

BACKGROUND In men with heart failure, nocturnal rostral fluid shift is associated with an overnight increase in the neck circumference (NC) and with severity of obstructive sleep apnea. Because the prevalence of obstructive sleep apnea is lower in women than in men with heart failure, we hypothesized that less fluid would shift into the neck in association with less severe obstructive sleep apn...

Sleep apnea is defined as repetitive episodes of decreased or total cessation of respiratory airflow during sleep, leading to a fall in oxygen saturation of 4% and sleep fragmentation. Sleep apnea can be central or obstructive. Central sleep apnea (CSA) is characterized by apneas secondary to diminution or cessation of thoraco-abdominal respiratory movements (due to dysfunction of central respi...

Obstructive sleep apnea is an exciting area for orthodontists to be involved. The level of awareness of sleep apnea and related health issues is growing rapidly. The demand of integrating sleep into the orthodontic practice shortly will be driven by the need of the societies as some of our patients will be shortly coming into our offices aware of sleep apnea. However, with our busy clinical ort...

Objective: To evaluate, industry independently, the accuracy of the Watch-PAT100 system (WP100) [Itamar Medical; Caesarea, Israel], a portable home sleep test, compared to polysomnography, the gold standard for diagnosing obstructive sleep apnea syndrome. Methods: Prospective clinical trial. 27 patients (24 male, 3 female) were evaluated at our institution's sleep laboratory. The apnea hypopnea...

UNLABELLED Obstructive sleep apnea and hypopnea syndrome in children (osas) has an estimated prevalence of up to 3% and can be associated with neurocognitive and behavioural abnormalities, and also cardiovascular complications. This study may help pediatricians, who are unaware of the problem, to recognize osas. STUDY DESIGN series of cases. AIM to describe the clinical characteristics and ...

BACKGROUND In patients with chronic heart failure (CHF), the presence of sleep-disordered breathing, including either obstructive sleep apnea or Cheyne-Stokes respiration-central sleep apnea, is associated with a poor prognosis. A large-scale clinical trial showed that continuous positive airway pressure (CPAP) did not improve the prognosis of such patients with CHF, probably because of insuffi...
