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...

OBJECTIVE The aim of this study is to compare patients treated with pharyngoplasty and those treated with palatoplasty for velopharyngeal insufficiency to establish what surgical procedure poses the highest risk for developing sleep apnea. The hypothesis tested in this study is that the incidence of obstructive sleep apnea syndrome associated with pharyngoplasty is greater than that associated ...

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 ...

OBJECTIVE To validate the pediatric obstructive sleep apnea screening tool for use in Brazil. MATERIALS AND METHODS The Brazilian version of this questionnaire, originally validated and tested in the United States, was developed as follows: (a) translation; (b) back-translation; (c) completion of the final version; (d) pre-testing. The questionnaire was applied prior to polysomnography to chi...

RATIONALE Opioids have become part of contemporary treatment in the management of chronic pain. However, chronic use of opioids has been associated with high prevalence of sleep apnea which could contribute to morbidity and mortality of such patients. OBJECTIVES The main aim of this study was to treat sleep apnea in patients on chronic opioids. METHODS Five consecutive patients who were ref...

The objective of this study was to determine whether different decreases in oxygen saturation (SaO2) or the presence of electroencephalographic arousals (EEGA) in the definition of hypopnea modify hypopnea index and apnea/hypopnea index and the prevalence of obstructive sleep apnea/hypopnea syndrome (OSAHS). A total of 20 polysomnographies performed in patients with OSAHS were analyzed. There a...

BACKGROUND The effect of sleep apnea on mortality and cardiovascular morbidity is mainly unknown. We aimed to study whether sleep apnea is related to stroke, death, or myocardial infarction in patients with symptomatic coronary artery disease. METHODS AND RESULTS A total of 392 men and women with coronary artery disease referred for coronary angiography were examined by use of overnight sleep...

OBJECTIVE Limited evidence suggests bariatric surgery can result in high cure rates for obstructive sleep apnea (OSA) in the morbidly obese. We performed a systematic review and meta-analysis to identify the effects of surgical weight loss on the apnea-hypopnea index. METHODS Relevant studies were identified by computerized searches of MEDLINE and EMBASE (from inception to March 17, 2008), an...
