Sleep architectural dysfunction and undiagnosed obstructive sleep apnea after chronic ischemic stroke.

Sleep Med 2021 Apr 15;83:45-53. Epub 2021 Apr 15.

The Florey Institute of Neuroscience and Mental Health, Melbourne, VIC, Australia; University of Melbourne, Melbourne, VIC, Australia.

Objective/background: Sleep-wake dysfunction is bidirectionally associated with the incidence and evolution of acute stroke. It remains unclear whether sleep disturbances are transient post-stroke or are potentially enduring sequelae in chronic stroke. Here, we characterize sleep architectural dysfunction, sleep-respiratory parameters, and hemispheric sleep in ischemic stroke patients in the chronic recovery phase compared to healthy controls.

Intermittent hypoxia changes the interaction of the kinin-VEGF system and impairs myocardial angiogenesis in the hypertrophic heart.

Physiol Rep 2021 May;9(9):e14863

Departamento de Psicobiologia, Universidade Federal de São Paulo, São Paulo, Brazil.

Intermittent hypoxia (IH) is a feature of obstructive sleep apnea (OSA), a condition highly associated with hypertension-related cardiovascular diseases. Repeated episodes of IH contribute to imbalance of angiogenic growth factors in the hypertrophic heart, which is key in the progression of cardiovascular complications. In particular, the interaction between vascular endothelial growth factor (VEGF) and the kallikrein-kinin system (KKS) is essential for promoting angiogenesis. Read More

Effect of continuous positive airway pressure on albuminuria in patients with obstructive sleep apnea: a meta-analysis.

Sleep Breath 2021 May 15. Epub 2021 May 15.

Department of Obstetrics & Gynecology, Nanri Branch of the First Hospital of Putian City, Putian, Fujian, China.

Sleep Bruxism: An Integrated Clinical View.

Sleep Med Clin 2021 Jun 18;16(2):373-380. Epub 2021 Apr 18.

Department of Integral Adult Care Dentistry, Temporomandibular Disorder and Orofacial Pain Program, Sleep & Pain Research Group, Faculty of Dentistry, Universidad de La Frontera, Avenida Francisco Salazar 01145, Temuco, Chile.

The vision of adult sleep bruxism (SB) has changed over time. Thus, among the most important concomitant factors of SB noted are the pathophysiological aspect, namely sleep arousal, obstructive sleep apnea, gastroesophageal pH/gastroesophageal reflux disease, and the use or abuse of certain substances. The aim of this article was to review the main clinically relevant pathophysiological SB-associated factors and a proposal for a diagnostic process. Read More
