J Stomatol Oral Maxillofac Surg 2021 Jun 9. Epub 2021 Jun 9.

Professor, Chief of the Service de Stomatologie et de Chirurgie Maxillo-faciale de la Pitié Salpétrière (France).

Objective: This pilot randomized crossover study evaluated the outcomes of two custom-made mandibular retention devices (MRDs), a computer-aided design (CAD)/computer-aided manufacturing (CAM) device (Narval CC™) and a non-CAD/CAM device (Narval™), on oropharyngeal airway volume in patients with obstructive sleep apnoea (OSA).

Suprascapular nerve block is a clinically attractive alternative to interscalene nerve block during arthroscopic shoulder surgery: a meta-analysis of randomized controlled trials.

J Orthop Surg Res 2021 Jun 11;16(1):376. Epub 2021 Jun 11.

Department of Orthopedic, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, No. 168 Litang Road, Dongxiaokou Town, Changping District, Beijing, 102218, China.

Obstructive sleep apnea prediction from electrocardiogram scalograms and spectrograms using convolutional neural networks.

Physiol Meas 2021 Jun 11. Epub 2021 Jun 11.

Biomedical Engineering, TOBB Ekonomi ve Teknoloji Universitesi, Sogutozu Cad. No:43, Cankaya, 06560, TURKEY.

Screening for atrial fibrillation in high-risk nursing home residents.

Heart Rhythm O2 2020 Apr 27;1(1):10-13. Epub 2020 Apr 27.

Department of Medicine, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, Buffalo, New York.

Sleep Apnea and Atrial Fibrillation: Role of the Cardiac Autonomic Nervous System.

Methodist Debakey Cardiovasc J 2021 Apr 25;17(1):49-52. Epub 2021 Mar 25.

Houston Methodist DeBakey Heart & Vascular Center, Houston Methodist Hospital, Houston, Texas.

Sleep apnea is highly associated with atrial fibrillation (AF), and both diseases are highly prevalent in the United States. The mechanistic underpinnings that contribute to their association remain uncertain, but numerous possible mechanisms have been proposed, including dysfunction of the cardiac autonomic nervous system (ANS). Studies have reported that apnea induces hyperactivity of the ANS, leading to increases in AF susceptibility. Read More
