INTRODUCTION: Obstructive sleep apnea is characterized by a reduced airflow through the upper airways during sleep. Two forms of obstructive sleep apnea are described: the central form and the obstructive form. The obstructive form is related to many factors, such as the craniofacial morphology. OBJECTIVE: To evaluate the correlation between the morphology of the cranial base, of the mandible and the maxilla, and obstructive sleep apnea severity. METHODS: Eighty-four patients, mean age of 50...

Obesity is a global epidemic in developed countries accounting for many of the metabolic and cardiorespiratory morbidities that occur in adults. These morbidities include type 2 diabetes, sleep-disordered breathing (SDB), obstructive sleep apnea, chronic intermittent hypoxia, and hypertension. Leptin, produced by adipocytes, is a master regulator of metabolism and of many other biological functions including central and peripheral circuits that control breathing. By binding to receptors on cells and neurons in the brainstem, hypothalamus, and carotid body, leptin links energy and metabolism to breathing...

The past two decades has seen a substantial rise in the use of opioids for chronic pain, along with opioid-related mortality and adverse effects. A contributor to opioid-associated mortality is the high prevalence of moderate/severe sleep-disordered breathing, including central sleep apnea and obstructive sleep apnea, in patients with chronic pain. Although evidence-based treatments are available for sleep-disordered breathing, patients are not frequently assessed for sleep-disordered breathing in pain clinics...

BACKGROUND: Obstructive sleep apnea (OSA) patients are at increased risk for pulmonary and cardiovascular complications; perioperative mortality risk is unclear. This report analyzes cases submitted to the OSA Death and Near Miss Registry, focusing on factors associated with poor outcomes after an OSA-related event. We hypothesized that more severe outcomes would be associated with OSA severity, less intense monitoring, and higher cumulative opioid doses. METHODS: Inclusion criteria were age ≥18 years, OSA diagnosed or suspected, event related to OSA, and event occurrence 1992 or later and <30 days postoperatively...

Sleep apnea is a common sleep disorder that causes repeated breathing interruption during sleep. The performance of automated apnea detection methods based on respiratory signals depend on the signals considered and feature extraction methods. Moreover, feature engineering techniques are highly dependent on the experts' experience and their prior knowledge about different physiological signals and conditions of the subjects. To overcome these problems, a novel deep recurrent neural network (RNN) framework is developed for automated feature extraction and detection of apnea events from single respiratory channel inputs...

PURPOSE OF REVIEW: The aim of this article is to summarize up-to-date research on the effects of obstructive sleep apnea (OSA) on retinal vascular conditions. RECENT FINDINGS: OSA is associated with the development of diabetic retinopathy, retinal vein occlusion, and central serous chorioretinopathy. The severity of OSA and biomarkers such as the apnea-hypopnea index (AHI) correlate with the severity of retinal disease. Dysregulation of CLOCK genes that govern circadian rhythm is associated with development of proliferative retinal disease...

We report the case of a 12-year-old girl referred to our pediatric sleep unit with a history of central sleep apnea (CSA), associated to transient episodes of tachypnea on polysomnography recordings. The patient was otherwise healthy, with no personal or family medical history, and had normal physical and neuropsychological examination. Brain magnetic resonance imaging (MRI) showed signs of cerebellar vermis dysplasia, but without the classical features of the molar tooth sign. The rest of the workup (genetic tests, blood tests, cardiac investigations) was normal, except for an increased peripheral chemosensitivity to carbon dioxide and oxygen...

NEW FINDINGS: What is the central question of this study? We investigated the effects of incremental ascent to high altitude on splenic contraction at rest and during voluntary breath holding, and the associated bradycardic diving response. We aimed to assess the relative contribution of the putative tonic splenic contraction to the hematological acclimatization process during HA ascent in native lowlanders. What is the main finding and its importance? We found that spleen volume decreased by -14...

PURPOSE: Adaptive servo-ventilation (ASV) is a therapy designed for patients with central sleep apnea (CSA) and Cheyne Stokes respiration. The aim of this study was to find predictors of ASV usage in patients with CSA in a routine sleep clinic cohort. METHODS: In this retrospective study, consecutive patients in whom ASV therapy was initiated at the University Hospital Regensburg between 2011 and 2015, were analyzed. Analysis included polysomnographies of diagnostic and ASV initiation nights, a phone questionnaire on ASV usage, readout of the ASV device 1 month after initiation ("early ASV usage," 1 month after ASV initiation), and the readout of the last month before a reappointment date set in 2015 ("late ASV usage," median 17 months after ASV initiation)...
