Quantitative EEG measures in REM and NREM sleep are associated with AHI and nocturnal hypoxemia in men.

Sleep 2019 Apr 20. Epub 2019 Apr 20.

The Health Observatory, Adelaide Medical School, University of Adelaide, The Queen Elizabeth Hospital Campus, Woodville, South Australia, Australia.

Study Objectives: Quantitative EEG measures of sleep may identify vulnerability to obstructive sleep apnea (OSA) sequelae, however, small clinical studies of sleep microarchitecture in OSA show inconsistent alterations. We examined relationships between quantitative EEG measures during rapid eye movement (REM) and non-REM (NREM) sleep and OSA severity among a large population-based sample of men while accounting for insomnia.

Methods: All-night EEG (F4-M1) recordings from full in-home polysomnography (Embletta X100) in 664 men with no prior OSA diagnosis (age ≥40) were processed following exclusion of artefacts. Read More

Clinical Characteristics of Obstructive Sleep Apnea in Psychiatric Disease.

J Clin Med 2019 Apr 18;8(4). Epub 2019 Apr 18.

Division of Pulmonology, Department of Clinical Therapeutics, National and Kapodistrian University of Athens School of Medicine, Alexandra Hospital, 11528 Athens, Greece.

Patients with serious psychiatric diseases (major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia and psychotic disorder) often complain about sleepiness during the day, fatigue, low energy, concentration problems, and insomnia; unfortunately, many of these symptoms are also frequent in patients with Obstructive Sleep Apnea (OSA). However, existing data about the clinical appearance of OSA in Psychiatric Disease are generally missing. The aim of our study was a detailed and focused evaluation of OSA in Psychiatric Disease, in terms of symptoms, comorbidities, clinical characteristics, daytime respiratory function, and overnight polysomnography data.

Quantifying the Magnitude of Pharyngeal Obstruction During Sleep Using Airflow Shape.

Eur Respir J 2019 Apr 18. Epub 2019 Apr 18.

Division of Sleep and Circadian Disorders, Department of Medicine, Brigham & Women's Hospital & Harvard Medical School, Boston, MA, USA.

Rationale: Non-invasive quantification of the severity of pharyngeal airflow obstruction would enable recognition of obstructive central manifestation of sleep apnoea, and identification of symptomatic individuals with severe airflow obstruction despite a low apnoea-hypopnoea index (AHI).

Objectives: Here we provide a novel method that uses simple airflow--time ("shape") features from individual breaths on an overnight sleep study to automatically and non-invasively quantify the of airflow obstruction without oesophageal catheterisation.

Methods: 41 individuals with suspected/diagnosed obstructive sleep apnoea (AHI range=0-91 events·hr) underwent overnight polysomnography with gold-standard measures of airflow (oronasal pneumotach, ) and ventilatory drive (calibrated intraoesophageal diaphragm EMG, ). Read More

Parasomnia overlap disorder with adolescent-onset presumed REM sleep behavior disorder converting to Parkinson's disease after 48 years.

Sleep Med 2019 Feb 12;57:97-99. Epub 2019 Feb 12.

Newcastle Regional Sleep Service, Freeman Hospital, Newcastle upon Tyne, UK; Institute of Neuroscience, Newcastle University, Newcastle upon Tyne, UK.

Background: It is now recognized that the vast majority of individuals with typical RBD will develop a synucleinopathy; usually 11-16 years after symptom onset. Parasomnia Overlap Disorder (POD) with adolescent-onset dream enactment behavior with phenoconversion to neurodegenerative disease after a long latency has not been previously described.

Patient: We present a case of a 65-year-old man with presumptive POD who had co-morbid childhood onset sleep walking and adolescent-onset dream enactment behavior beginning at age 17, with subsequent evolution to an increasingly troublesome REM sleep behavior disorder (RBD) at age 64 with Parkinson's Disease (PD) developing a year later.

Objective: Childhood adversity figures prominently in the clinical histories of children and adolescents suffering from a panoply of physical, mental or sleep disorders, including posttraumatic stress disorder. But the nature and prevalence of early adversity in the case of idiopathic nightmare-prone individuals have received little study. We characterize the types and frequencies of self-reported childhood adversity for nightmare-prone individuals using the developmentally sensitive Traumatic Antecedents Questionnaire (TAQ) and assess relationships between separation adversity and sleep spindles.

Tongue Stabilizing Device-Emergent Central Sleep Apnea: A Case Report.

J Clin Sleep Med 2019 Apr 2. Epub 2019 Apr 2.

Abstract: Treatment-emergent central sleep apnea is a phenomenon that has been reported after many obstructive sleep apnea treatment modalities. We present a case of demonstrating treatment-emergent central sleep apnea while using the tongue stabilizing device therapy. This case adds to the evidence that showed the effect of the supine position on the severity of central sleep apnea and shows the advantage of polysomnography follow-up after oral appliance therapy for central apnea assessment.

Real-Time Identification of Upper Airway Occlusion Using Electrical Impedance Tomography.

J Clin Sleep Med 2019 Apr 2. Epub 2019 Apr 2.

Study Objectives: Real-time monitoring of upper airway collapse during sleep could be instrumental for studies in biomechanics of obstructive sleep apnea (OSA) and selecting individualized treatment modalities. Although some imaging techniques are used under sedated sleep, none are available during the entire natural sleep process. We hypothesized that electrical impedance tomography (EIT) can be used for noninvasive continuous imaging of the upper airway during natural sleep and quantifying upper airway collapse in terms of its size.

Altered irisin/BDNF axis parallels excessive daytime sleepiness in obstructive sleep apnea patients.

Respir Res 2019 Apr 5;20(1):67. Epub 2019 Apr 5.

Department of Health Systems Management and Quality Management for Health Care, Faculty of Public Health, University of Debrecen, Nagyerdei krt. 98, Debrecen, 4032, Hungary.

Study Objectives: Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep-related breathing disorder, characterized by excessive daytime sleepiness (EDS), paralleled by intermittent collapse of the upper airway. EDS may be the symptom of OSAHS per se but may also be due to the alteration of central circadian regulation. Irisin is a putative myokine and has been shown to induce BDNF expression in several sites of the brain. Read More

Relationship of stroke volume to different patterns of Cheyne-Stokes respiration in heart failure.

Sleep 2019 Apr;42(4)

Sleep Research Laboratory of the University Health Network Toronto Rehabilitation Institute, Toronto, ON, Canada.

Study Objectives: In patients with heart failure (HF) and reduced left ventricular ejection fraction (HFrEF), stroke volume (SV) falls during hyperpnea of Cheyne-Stokes respiration with central sleep apnea (CSR-CSA). We have identified two distinct patterns of hyperpnea: positive, in which end-expiratory lung volume (EELV) remains at or above functional residual capacity (FRC), and negative, in which EELV falls below FRC. The increase in expiratory intrathoracic pressure generated by the latter should have effects on the heart analogous to external chest compression. Read More

Relation between ambulatory actigraphy and laboratory polysomnography in insomnia practice and research.

J Sleep Res 2019 Apr 2:e12854. Epub 2019 Apr 2.

Sleep Disorders and Research Center, Henry Ford Hospital, Detroit, Michigan.

Actigraphy is increasingly used in practice and research studies because of its relative low cost and decreased subject burden. How multiple nights of at-home actigraphy compare to one independent night of in-laboratory polysomnography (PSG) has not been examined in people with insomnia. Using event markers (MARK) to set time in bed (TIB) compared to automatic program analysis (AUTO) has not been systematically evaluated. Read More

Validation of 'Somnivore', a Machine Learning Algorithm for Automated Scoring and Analysis of Polysomnography Data.

Front Neurosci 2019 18;13:207. Epub 2019 Mar 18.

The Florey Institute of Neuroscience and Mental Health, Parkville, VIC, Australia.

Manual scoring of polysomnography data is labor-intensive and time-consuming, and most existing software does not account for subjective differences and user variability. Therefore, we evaluated a supervised machine learning algorithm, Somnivore, for automated wake-sleep stage classification. We designed an algorithm that extracts features from various input channels, following a brief session of manual scoring, and provides automated wake-sleep stage classification for each recording.
