Obstructive sleep apnea (OSA) occurs in more than 4 % of the adult population. Diagnoses for OSA in sleep clinics are costly and more than half of those submitted to a sleep clinic do not have OSA. A simple, easy, and portable homebased monitoring system to evaluate who are in high-or low risk of suffering from OSA would be beneficial. The system must be able to identify individuals with a high pre-test reliability regarding OSA with the aim of referral and further investigation. We aimed to develop a portable, smartphone, and homebased monitoring system to classify whether a patient screened for sleep apnea is at high risk or low risk of having OSA...

Obstructive sleep apnea (OSA) affects up to 14% of the population. OSA is characterized by recurrent apneas and hypopneas during sleep. The apnea-hypopnea index (AHI) is frequently used as a measure of OSA severity. In the current study, we explored the acoustic characteristics of hypopnea in order to distinguish it from apnea. We hypothesize that we can find audio-based features that can discriminate between apnea, hypopnea and normal breathing events. Whole night audio recordings were performed using a non-contact microphone on 44 subjects, simultaneously with the polysomnography study (PSG)...

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder. Previous studies associated OSA with anatomical abnormalities of the upper respiratory tract that may be reflected in the acoustic characteristics of speech. We tested the hypothesis that the speech signal carries essential information that can assist in early assessment of OSA severity by estimating apnea-hypopnea index (AHI). 198 men referred to routine polysomnography (PSG) were recorded shortly prior to sleep onset while reading a one-minute speech protocol...

Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by repeated episodes of complete or partial blockage of the upper airway. These episodes can interfere with sound sleep and have fatal health consequences. They can also reduce the flow of oxygen to vital organs, like the brain, and lead to brain damage. In this paper, we leverage the correlation between brain damage and OSA to design a prediction framework that can assess the severity level of the OSA condition, as well as estimate the Apnea-Hypopnea Index (AHI) using only features obtained during wakefulness...

Between 7-18 million Americans suffer from sleep disordered breathing (SDB), including those who suffer from obstructive sleep apnea (OSA). Despite this high prevalence and burden of OSA, existing diagnostic techniques remain impractical for widespread screening. In this study, we introduce a new model for OSA screening and describe an at-home wearable sleep mask (named ARAM) that can robustly track the wearers' sleep patterns. This monitoring is achieved using select sensors that enable screening and monitoring in a form-factor that can be easily self-instrumented...

BACKGROUND: An accurate, clinical screening tool for obstructive sleep apnea (OSA) that identifies patients for further diagnostic testing would assist in the diagnosis of this comorbidity. One example, the STOP-BANG questionnaire (SBQ), has been validated as a screening tool with high sensitivity. However, its specificity may result in a high false-positive rate. The aim of this study to determine if addition of the Modified Mallampati score to the SBQ improves its specificity. METHODS: The authors studied 162 patients referred to the Sleep Disorders Clinic at Yedikule Chest Disease Education and Research Hospital...

BACKGROUND: Atrial fibrillation (AF) constitutes the most prevalent arrhythmia affecting up-to 2% percent of general population. Apart from well-established risk factors which increase the odds for the development of AF e.g. age or arterial hypertension, recent analyses indicated that obstructive sleep apnea (OSA) may independently, negatively modify arrhythmia occurrence profile. Concurrently, erectile dysfunction (ED) is commonly neglected, potent marker of cardiovascular risk which considerably worsens men's psychological state...

OBJECTIVES: Sleep studies for diagnosing obstructive sleep apnea (OSA) in children are laborious, expensive, inconvenient, and often not readily available. Out-of-center sleep test (OCST) devices have been studied for diagnosing OSA in adults, but few OCST studies have been done in children. The purpose of this study was to clarify the diagnostic reliability of OCST devices for children. METHODS: OCSTs using pulse oximetry and in-laboratory polysomnography (PSG) were performed separately in 686 adults and 119 children...

As a surrogate measure of blood pressure, pulse transit time (PTT) is commonly used in studies investigating arterial function and respiratory sleep disturbance. A systematic search of the literature was conducted with the aim of reviewing the usefulness of the technique within pediatric sleep studies. All studies that used PTT as a diagnostic tool during sleep in infants, children or adolescents were considered. The search yielded 425 articles, of which 21 full-text articles met inclusion criteria, the majority reporting on obstructive sleep apnea (OSA)...

There is increasing awareness that health screening may prevent some acute coronary events. Yet, obstructive sleep apnea (OSA) is seldom screened for and its relation with coronary risk markers is not well established. Consecutive adults (n = 696) enrolled in a cardiovascular health screening program were approached to determine the feasibility of incorporating OSA screening. Screening included questionnaires and a home-based sleep study. High-sensitivity C-reactive protein was the primary coronary risk marker, and other laboratory- and exercise treadmill-based markers were also reported...

Obstructive sleep apnea (OSA) and atrial fibrillation (AF) are common conditions in the adult population and independently associated with increased morbidity and mortality. There is evidence, although not definitive, that OSA independently contributes to AF incidence and recurrence. Full polysomnography is expensive and may not be readily available to diagnose all patients with OSA and AF. Several patients with OSA do not present the classical signs and symptoms of OSA, impairing the accuracy of screening questionnaires for OSA...

Sleep disorders may interact with the law, making awareness important. Insufficient sleep and obstructive sleep apnea (OSA) are prevalent and associated with excessive sleepiness. Patients with excessive sleepiness may have civil or criminal liability if they fall asleep and cause a motor vehicle accident. Awareness of screening and treatment of OSA is increasing in certain industries. Parasomnia associated sleep-related violence represents a challenge to clinicians, who may be called on to consider parasomnia as a contributing, mitigating, or exculpatory factor in criminal proceedings...

Obstructive sleep apnea (OSA) is a chronic disease affecting millions of people worldwide. Untreated OSA can lead to about a 2-fold increase in medical expenses, mainly because of cardiovascular morbidity. OSA is highly prevalent in the surgical population, with an increased risk of perioperative complications. This article describes the perioperative and long-term social and economic benefits of preoperative screening for OSA. Screening patients to identify high-risk OSA is important to decrease the adverse outcomes and associated health care costs in the perioperative period...

Martin R Cowie
Many patient with, or at risk of, cardiovascular disease have sleep disordered breathing (SDB), which can be either obstructive (with intermittent collapse of the upper airway) or central (episodic loss of respiratory drive). SDB is associated with sleep disturbance, hypoxemia, hemodynamic changes, and sympathetic activation. Such patients have a worse prognosis than those without SDB. Mask-based therapies of positive airway pressure targeted at SDB can improve measures of sleep quality and partially normalize the sleep and respiratory physiology, but recent randomized trials of cardiovascular outcomes in SDB have either been neutral (obstructive sleep apnea) or suggested the possibility of harm, likely from increased sudden death, in central sleep apnea...

Tracheal cartilaginous sleeve (TCS) is a rare and previously unrecognized source of morbidity and mortality in patients with certain craniosynostosis syndromes. There is a paucity of reporting on this airway anomaly, and the true incidence of TCS is largely unknown. The purpose of this study was to investigate the incidence of TCS among patients with syndromic craniosynostosis at our institution. Patients with syndromic craniosynostosis who underwent direct bronchoscopy and laryngoscopy were evaluated retrospectively by pediatric otolaryngologists for the presence of TCS and associated anomalies...
