Chemoreflex failure and sleep-disordered breathing in familial dysautonomia: Implications for sudden death during sleep.

Auton Neurosci 2019 May 15;218:10-15. Epub 2019 Feb 15.

Department of Neurology, Dysautonomia Center, New York University School of Medicine, New York, NY, United States of America. Electronic address:

Familial dysautonomia (Riley-Day syndrome, hereditary sensory and autonomic neuropathy type III) is a rare autosomal recessive disease characterized by impaired development of primary sensory and autonomic neurons resulting in a severe neurological phenotype, which includes arterial baroreflex and chemoreflex failure with high frequency of sleep-disordered breathing and sudden death during sleep. Although a rare disease, familial dysautonomia represents a unique template to study the interactions between sleep-disordered breathing and abnormal chemo- and baroreflex function. In patients with familial dysautonomia, ventilatory responses to hypercapnia are reduced, and to hypoxia are almost absent. Read More

Opioid Sensitivity in Children with and without Obstructive Sleep Apnea.

Anesthesiology 2019 Mar 8. Epub 2019 Mar 8.

From the Department of Anesthesiology, Washington University in St. Louis, School of Medicine, St. Louis, Missouri (M.C.M., L.J., A.S., E.D.K.) the Department of Anesthesiology, Duke University School of Medicine, Durham, North Carolina (E.D.K.).

What We Already Know About This Topic: Children with obstructive sleep apnea are at greater risk for postoperative hypoxia and other respiratory events as compared with children without this disorderThere is some reason to believe that children with obstructive sleep apnea may be at greater risk for opioid-induced respiratory depression due to increased sensitivity to the drugs WHAT THIS ARTICLE TELLS US THAT IS NEW: The authors hypothesized that children with obstructive sleep apnea would be more sensitive to the effects of an opioid (remifentanil) on pupil size-a very good indicator of opioid effectsWhile remifentanil did reduce pupil size in the expected dose-related fashion, there were no differences between children with obstructive sleep apnea and those withoutWhile the authors did not observe any differences in the effect of remifentanil on respiration, the study was not designed to examine this factor in detail BACKGROUND:: Opioids are a mainstay of perioperative analgesia. Opioid use in children with obstructive sleep apnea is challenging because of assumptions for increased opioid sensitivity and assumed risk for opioid-induced respiratory depression compared to children without obstructive sleep apnea. These assumptions have not been rigorously tested. Read More

Continuous Positive Airway Pressure Effectively Alleviates Arrhythmias in Patients with Obstructive Sleep Apnea: Possible Relationship with Counteracting Oxidative Stress.

Curr Med Sci 2019 Feb 13;39(1):52-58. Epub 2019 Mar 13.

Department of Otolaryngology-Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong University, Jinan, 250021, China.

This work is aimed at exploring the clinical efficacy of continuous positive airway pressure (CPAP) in treatment of patients with arrhythmias combined with obstructive sleep apnea (OSA). Through evaluating serum native thiol, malonaldehyde (MDA) and nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase) in these patients and describing the effects on oxidative parameters of CPAP therapy for 3 months, we confirmed the impact of oxidative stress on arrhythmias. A total of 64 patients with OSA combined with arrhythmias were collected from April 2014 to April 2017 with full clinical information. Read More

Transient upregulation of TASK-1 expression in the hypoglossal nucleus during chronic intermittent hypoxia is reduced by serotonin 2A receptor antagonist.

J Cell Physiol 2019 Mar 12. Epub 2019 Mar 12.

Institute of Respiratory Disease, The First Hospital of China Medical University, Shenyang, Liaoning, China.

Hypoglossal motoneurons innervate genioglossus muscle, the contraction of which is critical in the maintenance of upper airway patency in patients with obstructive sleep apnea. As a potassium channel distributed in hypoglossal motoneurons, TWIK-related acid-sensitive K+ channel-1 (TASK-1) could be inhibited by 5-HT. This study aimed to investigate if TASK-1 expression in hypoglossal nucleus could be influenced by chronic intermittent hypoxia (CIH) and 5-HT receptors antagonist. Read More

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.
