Sleep staging from single-channel EEG with multi-scale feature and contextual information.

Sleep Breath 2019 Mar 12. Epub 2019 Mar 12.

Academy for Advanced Interdisciplinary Studies, Peking University, Beijing, 100871, China.

Purpose: Portable sleep monitoring devices with less-attached sensors and high-accuracy sleep staging methods can expedite sleep disorder diagnosis. The aim of this study was to propose a single-channel EEG sleep staging model, SleepStageNet, which extracts sleep EEG features by multi-scale convolutional neural networks (CNN) and then infers the type of sleep stages by capturing the contextual information between adjacent epochs using recurrent neural networks (RNN) and conditional random field (CRF).

Methods: To verify the feasibility of our model, two datasets, one composed by two different single-channel EEGs (Fpz-Cz and Pz-Oz) on 20 healthy people and one composed by a single-channel EEG (F4-M1) on 104 obstructive sleep apnea (OSA) patients with different severities, were examined.

Objective Relationship Between Sleep Apnea and Frequency of Snoring Assessed by Machine Learning.

J Clin Sleep Med 2019 Mar 15;15(3):463-470. Epub 2019 Mar 15.

Sleep Research Laboratories of the Toronto Rehabilitation Institute and Toronto General Hospital, University Health Network, Toronto, Ontario, Canada.

Study Objectives: Snoring is perceived to be directly proportional to sleep apnea severity, especially obstructive sleep apnea (OSA), but this notion has not been thoroughly and objectively evaluated, despite its popularity in clinical practice. This might lead to overdiagnosis or underdiagnosis of OSA. The goal of this study is to examine this notion and objectively quantify the relationship between sleep apnea and snoring detected using advanced signal processing algorithms. Read More

The role of home sleep testing for evaluation of patients with excessive daytime sleepiness: focus on obstructive sleep apnea and narcolepsy.

Sleep Med 2019 Jan 28. Epub 2019 Jan 28.

Yale Pulmonary and Critical Care Medicine, New Haven, CT, USA. Electronic address:

Excessive daytime sleepiness (EDS) is a common complaint in the general population, which may be associated with a wide range of sleep disorders and other medical conditions. Narcolepsy is a sleep disorder characterized primarily by EDS, which involves a substantial burden of illness but is often overlooked or misdiagnosed. In addition to identifying low cerebrospinal fluid (CSF) hypocretin (orexin) levels, evaluation for narcolepsy requires in-laboratory polysomnography (PSG). Read More

Using a modified version of the "STOP-BANG" questionnaire and nocturnal oxygen desaturation to predict obstructive sleep apnea after stroke or TIA.

Sleep Med 2019 Jan 7. Epub 2019 Jan 7.

L.C. Campbell Cognitive Neurology Research Unit, Heart and Stroke Foundation Canadian Partnership for Stroke Recovery, University of Toronto Stroke Program, Hurvitz Brain Sciences Research Program, Sunnybrook Research Institute, Sunnybrook Health Sciences Centre, University of Toronto, Toronto, ON, Canada; Department of Medicine, Division of Neurology, University of Toronto, Toronto, ON, Canada.

Purpose: Obstructive sleep apnea (OSA) is a risk factor and common morbidity for stroke and transient ischemic attack (TIA). However, screening for OSA in patients with stroke or TIA is uncommonly performed, due in part to difficulties associated with conducting polysomnography (PSG) and Home Sleep Apnea Tests (HSATs). The 8-point "STOP-BANG" questionnaire has been shown to have high methodological quality in screening for OSA. Read More

Apnea hypopnea index during rapid eye movement sleep with diabetic retinopathy in patients with type 2 diabetes.

J Clin Endocrinol Metab 2019 Jan 11. Epub 2019 Jan 11.

Department of Endocrinology and Metabolism, Toranomon Hospital, Tokyo, Japan.

Context: Recent studies based on home sleep apnea testing (HSAT) reported the potential association of sleep disordered breathing (SDB), such as obstructive sleep apnea (OSA), with diabetic retinopathy (DR). A few studies showed that the apnea hypopnea index during rapid eye movement sleep (REM-AHI) is associated with glycated hemoglobin and hypertension, two known risk factors for DR. However, there are no studies that have evaluated the association of REM-AHI with DR because previous studies were based on HSAT. Read More

The Clinical Impact of Systematic Screening for Obstructive Sleep Apnea in a Type 2 Diabetes Population-Adherence to the Screening-Diagnostic Process and the Acceptance and Adherence to the CPAP Therapy Compared to Regular Sleep Clinic Patients.

Front Endocrinol (Lausanne) 2018 29;9:714. Epub 2018 Nov 29.

Second Internal Medicine Department, Vinohrady Teaching Hospital, Prague, Czechia.

Obstructive sleep apnea (OSA) is a common disorder in Type 2 diabetes (T2D) patients further increasing their already high cardiovascular risk. As T2D patients typically not report OSA symptoms, systematic screening for OSA in this population is warranted. We aimed to determine the readiness of T2D patients to undergo screening and to compare their adherence to continuous positive airway pressure (CPAP) therapy with "regular" sleep clinic patients who typically seek medical advice on their own initiative.

Automatic identification of sleep and wakefulness using single-channel EEG and respiratory polygraphy signals for the diagnosis of obstructive sleep apnea.

J Sleep Res 2019 Apr 26;28(2):e12795. Epub 2018 Nov 26.

Département de Pneumologie, Centre Hospitalier Universitaire, Angers, France.

Polysomnography (PSG) is necessary for the accurate estimation of total sleep time (TST) and the calculation of the apnea-hypopnea index (AHI). In type III home sleep apnea testing (HSAT), TST is overestimated because of the lack of electrophysiological sleep recordings. The aim of this study was to evaluate the accuracy and reliability of a novel automated sleep/wake scoring algorithm combining a single electroencephalogram (EEG) channel with actimetry and HSAT signals.

Association between diet quality and sleep apnea in the Multi-Ethnic Study of Atherosclerosis.

Sleep 2019 Jan;42(1)

Division of Sleep and Circadian Disorders, Brigham and Women's Hospital, Boston, MA.

Rationale: Although short sleep duration has been linked to unhealthy dietary patterns, little is known about the association of obstructive sleep apnea (OSA), a disorder characterized by sleep fragmentation and diet.

Study Objectives: Investigate associations between diet quality and OSA in the Multi-Ethnic Study of Atherosclerosis and assess whether reductions in slow-wave sleep (stage N3) and rapid eye movement (REM) sleep are potential mediators for these associations.

Methods: A diverse population (N = 1813) completed a food frequency questionnaire and underwent Type 2 in-home polysomnography, which included measurement of N3 and REM sleep and apnea-hypopnea index (AHI). Read More

Addition of frontal EEG to adult home sleep apnea testing: does a more accurate determination of sleep time make a difference?

Sleep Breath 2018 Dec 11;22(4):1179-1188. Epub 2018 Oct 11.

Division of Pulmonary, Critical Care, and Sleep Medicine, New York University School of Medicine, New York, NY, USA.

Rationale: Home sleep apnea testing (HSAT) typically does not include electroencephalogram (EEG) monitoring for sleep assessment. In patients with insomnia and low sleep efficiency, overestimation of the sleep period can result from absence of EEG, which will reduce sleep disordered breathing (SDB) indices and may lead to a false-negative result.

Objective: To validate a single channel frontal EEG for scoring sleep versus wake against full EEG during polysomnography, and then to examine the utility of adding this single channel EEG to standard HSAT to prevent false-negative results. Read More

Devices for home detection of obstructive sleep apnea: A review.

Sleep Med Rev 2018 10 17;41:149-160. Epub 2018 Feb 17.

Charité Universitatsmedizin, Sleep Center, Germany; International Clinical Research Center, St. Anne's University Hospital Brno, Brno, Czech Republic.

One of the most common sleep-related disorders is obstructive sleep apnea, characterized by a reduction of airflow while breathing during sleep and cause significant health problems. This disorder is mainly diagnosed in sleep labs with polysomnography, involving high costs and stress for the patient. To address this situation multiple systems have been proposed to conduct the examination and analysis in the patient's home, using sensors to detect physiological signals that are examined by algorithms.

Noncontact identification of sleep-disturbed breathing from smartphone-recorded sounds validated by polysomnography.

Sleep Breath 2019 Mar 18;23(1):269-279. Epub 2018 Jul 18.

Resonea Inc., 11445 E Via Linda, Suite 2 # 224, Scottsdale, AZ, 85259, USA.

Purpose: Diagnosis of obstructive sleep apnea by the gold-standard of polysomnography (PSG), or by home sleep testing (HST), requires numerous physical connections to the patient which may restrict use of these tools for early screening. We hypothesized that normal and disturbed breathing may be detected by a consumer smartphone without physical connections to the patient using novel algorithms to analyze ambient sound.

Methods: We studied 91 patients undergoing clinically indicated PSG. Read More

Polysomnography for Obstructive Sleep Apnea Should Include Arousal-Based Scoring: An American Academy of Sleep Medicine Position Statement.

J Clin Sleep Med 2018 Jul 15;14(7):1245-1247. Epub 2018 Jul 15.

Division of Sleep Medicine, Department of Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.

Abstract: The diagnostic criteria for obstructive sleep apnea (OSA) in adults, as defined in the International Classification of Sleep Disorders, Third Edition, requires an increased frequency of obstructive respiratory events demonstrated by in-laboratory, attended polysomnography (PSG) or a home sleep apnea test (HSAT). However, there are currently two hypopnea scoring criteria in The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications (AASM Scoring Manual). This dichotomy results in differences among laboratory reports, patient treatments and payer policies. Read More

Authors:
Neil Freedman

Chest 2019 Jan 5;155(1):227-233. Epub 2018 Jul 5.

Division of Pulmonary, Critical Care, Allergy and Immunology, Department of Medicine, Northshore University Health System, Evanston, IL. Electronic address:

As the cost of health care continues to escalate, payers are adapting by moving away from models based on traditional fee-for-service reimbursement to models focused on rewarding care delivery that reduces costs and improves quality. These alternative payment models (APMs) are being introduced by government and commercial payers and will likely become the norm over time. Recent changes in sleep medicine related to advances in technology and approaches by payers for the management of OSA make this an appropriate time to incorporate the delivery of sleep medicine services into APMs. Read More

A Comparison of Two Nights of Ambulatory Sleep Testing in Arrhythmia Patients.

Sleep Disord 2018 3;2018:2394146. Epub 2018 Jun 3.

Department of Psychiatry, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada.

Introduction: Obstructive sleep apnea (OSA) is common and usually underdetected in patients with cardiac arrhythmia. Ambulatory sleep testing may provide an alternative method for detection of OSA under realistic conditions compared to in-laboratory polysomnography. We aimed to (1) determine the sleep architecture in arrhythmia patients; (2) detect differences in sleep parameters between patients with and without OSA; and (3) compare the results of two consecutive nights of unattended ambulatory sleep testing.
