Obstructive sleep apnoea but not central sleep apnoea is associated with left ventricular remodelling after acute myocardial infarction.

Clin Res Cardiol 2020 Jun 9. Epub 2020 Jun 9.

Department of Internal Medicine II, University Medical Centre Regensburg, Franz-Josef-Strauß-Allee 11, 93053, Regensburg, Germany.

Obejctive: Obstructive sleep apnoea (OSA) increases left ventricular transmural pressure more than central sleep apnoea (CSA) owing to negative intrathoracic pressure swings. We tested the hypothesis that the severity of OSA, and not CSA, is therefore associated with spheric cardiac remodelling after acute myocardial infarction.

Methods: This sub-analysis of a prospective observational study included 24 patients with acute myocardial infarction who underwent primary percutaneous coronary intervention. Read More

Components of the renin-angiotensin system (RAS) situated within the carotid body or central nervous system may promote hypoxia-induced chemoreceptor reflex sensitization or central sleep apnea (CSA). We determined if losartan, an angiotensin-II type-I receptor (ATR) antagonist, would attenuate chemoreceptor reflex sensitivity before or after 8 h of nocturnal hypoxia, and consequently CSA severity. In a double-blind, randomized, placebo-controlled, crossover protocol, 14 men (age: 25 ± 2 years; BMI: 24. Read More

Oral Appliances in the Management of Obstructive Sleep Apnea.

Sleep Med Clin 2020 Jun;15(2):241-250

Department of Orthodontics, National Dental Centre Singapore, 5 Second Hospital Avenue, Singapore 168938, Singapore.

Obstructive sleep apnea (OSA) is a multifactorial condition, and an interdisciplinary approach to diagnosis forms the basis for effective treatment planning. Craniofacial structure and attached soft tissues and muscles play a central role in OSA. Evidence-based studies demonstrate the effectiveness of oral appliances for mandibular advancement and tongue stabilization in managing OSA, and current clinical standards of practice recommend the use of oral appliances to treat OSA when patients cannot tolerate continuous positive airway pressure (CPAP).

Sleep apnea-hypopnea syndrome caused by ankylosing spondylitis: A case report.

Medicine (Baltimore) 2020 May;99(19):e20055

Department of Respiratory Medicine, Qinghai University Affiliated Hospital, Xining.

Introduction: Sleep apnea-hypopnea syndrome (SAHS) is a multifactorial disease characterized by recurrent hypopnea or respiratory interruption during sleep, which causes intermittent hypoxemia, hypercapnia, and sleep structure disturbances. An association between ankylosing spondylitis (AS) and the type of SAHS has rarely been reported in the literature. Here, we present a case of SAHS in a patient with AS and discuss the possible mechanism underlying the type of SAHS. Read More

Current Long-Term Pharmacotherapies for the Management of Obesity.

J Obes Metab Syndr 2020 Jun;29(2):99-109

Division of Endocrinology and Metabolism, Department of Internal Medicine, Sejong General Hospital, Bucheon, Korea.

Obesity is a serious and growing worldwide health challenge associated with type 2 diabetes mellitus, cardiovascular disease, osteoarthritis, some cancers, sleep apnea, asthma, and nonalcoholic fatty liver. The Korean Society for the Study of Obesity recommends that pharmacotherapy should be considered when intensive lifestyle modifications fail to achieve a weight reduction in obese patients with a body mass index ≥25 kg/m. Long-term medications for obesity have traditionally fallen into two major categories: centrally acting anorexiant medications and peripherally acting medications, such as orlistat. Read More

Transoral Endoscopic Coblation Tongue Base Surgery in Obstructive Sleep Apnea: Resection versus Ablation.

ORL J Otorhinolaryngol Relat Spec 2020 May 6:1-8. Epub 2020 May 6.

Department of Head-Neck Surgery, Otolaryngology, Head-Neck and Oral Surgery Unit, Morgagni Pierantoni Hospital, Azienda USL della Romagna, Forlì, Italy.

Background: A new transoral tongue base surgical procedure for the treatment of snoring and obstructive sleep apnea (OSA) is described. It is named "Robo-Cob" technique because it is similar to transoral robotic surgery (TORS) but it is performed by means of coblation technology in order to resect the tongue base in countries where TORS is not an available option for such benign conditions.

Methods: In this prospective, randomized, controlled trial, the new Robo-Cob technique was carried out in 25 adult OSA patients with confirmed tongue base hypertrophy at preoperative drug-induced sedation endoscopy. Read More

Proteomic biomarkers of sleep apnea.

Sleep 2020 May 5. Epub 2020 May 5.

Department of Medicine and Clinical Research Core, Weill Cornell Medicine - Qatar, Qatar Foundation - Education City, Doha, Qatar.

Obstructive sleep apnea (OSA) is characterized by recurrent partial to complete upper airway obstructions during sleep, leading to repetitive arousals and oxygen desaturations. Although many OSA biomarkers have been reported individually, only a small subset have been validated through both cross-sectional and intervention studies. Here, we used a highly multiplexed aptamer array (SomaScan) for proteomic analysis of serum samples from 713 individuals in the Stanford Sleep Cohort, a patient-based registry. Read More

Sleep-Induced Glottis Closure in Multiple System Atrophy Evaluated by Four-Dimensional Computed Tomography.

Front Med (Lausanne) 2020 17;7:132. Epub 2020 Apr 17.

Department of Otolaryngology, The University of Tokyo, Tokyo, Japan.

Multiple system atrophy (MSA) is a progressive neurodegenerative disorder. Since patients with MSA often have sleep-related respiratory disorders including upper-airway obstruction and/or central sleep disturbance, appropriate evaluation of the upper airway especially during sleep may be indispensable. Fiberoptic laryngoscopy during diazepam-induced sleep has been reported for upper-airway obstruction verification. Read More

Plasticity of cardiovascular chemoreflexes after prolonged unilateral carotid body denervation: implications for its therapeutic use.

Am J Physiol Heart Circ Physiol 2020 05 24;318(5):H1325-H1336. Epub 2020 Apr 24.

Centro de Fisiología Celular e Integrativa, Facultad de Medicina, Clínica Alemana, Universidad del Desarrollo, Santiago, Chile.

Unilateral carotid body denervation has been proposed as treatment for sympathetic-related human diseases such as systolic heart failure, hypertension, obstructive sleep apnea, and cardiometabolic diseases. The long-term therapeutic effects of carotid body removal will be maintained if the remnant "buffer nerves," that is, the contralateral carotid nerve and the aortic nerves that innervate second-order neurons at the solitary tract nuclei (NTS), do not modify their contributions to the cardiovascular chemoreflexes. Here, we studied the cardiovascular chemoreflexes 1 mo after unilateral carotid body denervation either by excision of the petrosal ganglion (petrosal ganglionectomy, which eliminates central carotid afferents) or exeresis of a segment of one carotid nerve (carotid neurectomy, which preserves central afferents).

Adaptive servo-ventilation therapy does not favourably alter sympatho-vagal balance in sleeping patients with systolic heart failure and central apnoeas: Preliminary data.

Int J Cardiol 2020 Apr 2. Epub 2020 Apr 2.

Institute of Life Sciences, Scuola Superiore Sant'Anna, Pisa, Italy; Cardiology and Cardiovascular Medicine Division, Fondazione Toscana Gabriele Monasterio, National Research Council, CNR-Regione Toscana, Pisa, Italy.

Background: In contrast to continuous positive airway pressure (CPAP), the use of adaptive servo-ventilation (ASV) for treatment of central sleep apnoea (CSA) was associated with increased mortality in patients with chronic systolic heart failure (CHF). In order to characterize the interplay between sleep-disordered breathing, CHF and sympathovagal balance (SVB) this study investigated the effect of nocturnal CPAP and ASV on SVB in CSA patients with or without CHF.

Methods: Thirty-seven patients with ongoing positive airway pressure therapy (CPAP or ASV) for CSA (17 patients with systolic CHF - left ventricular ejection fraction <50% - and 20 patients with CSA but no CHF) underwent evaluation of SVB (spectral analysis of heart rate -HRV- and diastolic blood pressure variability) during full nocturnal polysomnography.
