Assessment of Cardiorespiratory Interactions during Apneic Events in Sleep via Fuzzy Kernel Measures of Information Dynamics.

Entropy (Basel) 2021 May 31;23(6). Epub 2021 May 31.

Department of Engineering, University of Palermo, 90128 Palermo, Italy.

Apnea and other breathing-related disorders have been linked to the development of hypertension or impairments of the cardiovascular, cognitive or metabolic systems. The combined assessment of multiple physiological signals acquired during sleep is of fundamental importance for providing additional insights about breathing disorder events and the associated impairments. In this work, we apply information-theoretic measures to describe the joint dynamics of cardiorespiratory physiological processes in a large group of patients reporting repeated episodes of hypopneas, apneas (central, obstructive, mixed) and respiratory effort related arousals (RERAs).

Interdisciplinary Weight Loss and Lifestyle Intervention for Obstructive Sleep Apnoea in Adults: Rationale, Design and Methodology of the INTERAPNEA Study.

Nutrients 2019 Sep 15;11(9). Epub 2019 Sep 15.

Sleep and Health Promotion Laboratory, Mind, Brain and Behaviour Research Centre (CIMCYC), University of Granada, 18011 Granada, Spain.

Obesity is a major risk factor for obstructive sleep apnoea (OSA), the most common sleep-disordered breathing related to neurocognitive and metabolic syndromes, type II diabetes, and cardiovascular diseases. Although strongly recommended for this condition, there are no studies on the effectiveness of an interdisciplinary weight loss and lifestyle intervention including nutrition, exercise, sleep hygiene, and smoking and alcohol cessation. INTERAPNEA is a randomised controlled trial with a two-arm parallel design aimed at determining the effects of an interdisciplinary tailored weight loss and lifestyle intervention on OSA outcomes.

Zhonghua Yi Xue Za Zhi 2019 Jun;99(24):1864-1869

Laboratory of Anesthesia and Critical Care Medicine, Translational Neuroscience Center, West China Hospital, Sichuan University, Chengdu 610041, China.

To examine the association between mixed sleep apnea (MA) and treatment-emergent central sleep apnea (TE-CSA). A total of 256 patients meeting the diagnostic criteria of moderate to severe obstructive sleep apnea (OSA) based on overnight polysomnography (PSG) and receiving continuous positive airway pressure (CPAP) therapy in West China Hospital, Sichuan University during the period from August 2013 to November 2018 were enrolled in the study. Based on the mixed apnea index (MAI) and apnea-hypopnea index (AHI) in the baseline PSG study during non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep, the subjects were categorized into three groups of A (MAI=0/h, 110), B (NREM-MAI≥5/h and REM-MAI<5/h, 72) and C (REM-MAI≥5/h and NREM-MAI< 5/h, 74).

Alcohol and sleep-related problems.

Curr Opin Psychol 2019 12 19;30:117-122. Epub 2019 Apr 19.

Corporal Michael J. Crescenz VA Medical Center, Philadelphia, PA 19104, United States; Perelman School of Medicine, Philadelphia, PA 19104, United States. Electronic address:

Alcohol is one of the most commonly used psychoactive substances in the community. Many individuals use alcohol for its sleep-promoting effects. Nonetheless, alcohol disrupts sleep through multiple mechanisms, such as disrupting electrophysiologic sleep architecture, triggering insomnia, and contributing to abnormalities of circadian rhythms and short sleep duration (SSD) in cross-sectional studies.

On the generalizability of ECG-based obstructive sleep apnea monitoring: merits and limitations of the Apnea-ECG database.

Annu Int Conf IEEE Eng Med Biol Soc 2018 Jul;2018:6022-6025

Obstructive sleep apnea syndrome (OSAS) is a sleep disorder that affects a large part of the population and the development of algorithms using cardiovascular features for OSAS monitoring has been an extensively researched topic in the last two decades. Several studies regarding automatic apneic event classification using ECG derived features are based on the public Apnea-ECG database available on PhysioNet. Although this database is an excellent starting point for apnea topic investigations, in our study we show that algorithms for apneic-epochs classification that are successfully trained on this database (sensitivity < 85%, false detection rate <20%) perform poorly (sensitivity\textit<55%, false detection rate < 40%) in other databases which include patients with a broader spectrum of apneic events and sleep disorders.

Advances and New Approaches to Managing Sleep-Disordered Breathing Related to Chronic Pulmonary Disease.

Sleep Med Clin 2016 Jun 8;11(2):257-64. Epub 2016 Mar 8.

Pulmonary, Critical Care and Sleep Medicine, Mayo Clinic, 200 1st Street Southwest, Rochester, MN 55905, USA. Electronic address:

Chronic obstructive pulmonary disease (COPD) is a common disease affecting about 20 million US adults. Sleep-disordered breathing (SDB) problems are frequent and poorly characterized for patients with COPD. Both the well-known success of noninvasive ventilation (NIV) in the acute COPD exacerbation in the hospital setting and that NIV is the cornerstone of chronic therapy for SDBs have urged the attention of the medical community to determine the impact of NIV on chronic COPD management with and without coexisting SDBs.

Respiratory Variability during Sleep in Methadone Maintenance Treatment Patients.

J Clin Sleep Med 2016 Apr 15;12(4):607-16. Epub 2016 Apr 15.

Woolcock Institute of Medical Research and Sydney Medical School, University of Sydney, Glebe, New South Wales, Australia.

Study Objectives: Methadone maintenance treatment (MMT) patients have a high prevalence of central sleep apnea and ataxic breathing related to damage to central respiratory rhythm control. However, the quantification of sleep apnea indices requires laborious manual scoring, and ataxic breathing pattern is subjectively judged by visual pattern recognition. This study proposes a semi-automated technique to characterize respiratory variability in MMT patients. Read More

Auto-adjusting and advanced positive airway pressure therapeutic modalities.

Semin Respir Crit Care Med 2014 Oct 29;35(5):593-603. Epub 2014 Oct 29.

Division of Pulmonary and Critical Care Medicine, Clinical Immunology and Allergy, David Geffen School of Medicine, Los Angeles, California.

Continuous positive airway pressure (CPAP) therapy is the first-line treatment for obstructive sleep apnea (OSA). Although the gold standard for the treatment of OSA, CPAP may not be the optimal modality to treat more complex sleep disordered breathing such as Cheyne-Stokes respirations, opioid-induced central apnea, and complex sleep disordered breathing related to chronic hypoventilation syndromes (obesity-hypoventilation syndrome, restrictive thoracic disease due to neuromuscular or thoracic cage disease, chronic obstructive pulmonary disease). Newer generation auto-adjusting PAP devices are increasingly being used to treat OSA. Read More
