background and objective: obstructive sleep apnea syndrome (osas) is a prevalent disease in adults. limited evidence regarding the effect of severity of sleep apnea and depression on heart rate variability (hrv) indices exists. hence, we decided to focus on the association between hrv and severity of osas based on depression score. materials and methods: a total of 193 patients with confirmed o...

background and objective: obstructive sleep apnea (osa) is defined as a sleep disordered breathing due to partial or complete obstruction of upper airways. this study aimed to investigate treatment outcomes and clinical complications among patients with osa who underwent upper airway surgery in clinical settings. materials and methods: all patients undergone upper airway surgery for osa were ca...

Hypertension is a common comorbidity in obstructive sleep apnea/hypopnea syndrome (OSAHS). OSAHS can raise blood pressures to pre-hypertensive and hypertensive ranges, increase the prevalence of 'non-dipping' overnight pressure patterns, risk resistant hypertension.

OBJECTIVE Altitude can affect the diagnostic accuracy of portable monitors used to diagnose suspected obstructive sleep apnea syndrome on the basis of oxygen desaturation measurements. The aim of this study was to determine agreement between the desaturation index measured by oximetry and the apnea-hypopnea index measured by polysomnography in Mexico City (2240 m above sea level). We also wishe...

BACKGROUND It is unknown whether short sleep duration, obstructive sleep apnea, and overnight shift work are associated with the risk of recurrent cardiovascular events in patients after an acute coronary syndrome. METHODS AND RESULTS SOLID-TIMI 52 (The Stabilization of PLaques UsIng Darapladib-Thrombolysis in Myocardial Infarction 52 Trial) was a multinational, double-blind, placebo-controll...

PURPOSE To determine whether narrowing of the oropharynx increases during relaxation in patients with severe obstructive sleep apnea syndrome. MATERIALS The study included 23 adult men in whom polysomnography had established a diagnosis of obstructive sleep apnea syndrome. Subjects had an average of 53 episodes of sleep apnea per hour, with each episode lasting 40 seconds or more. Oxygen satu...

We describe a case series of 4 patients with varying degrees of obstructive sleep apnea who incidentally had a history of nocturnal leg cramps. None of the patients had periodic limb movements during the study and denied symptoms consistent with restless legs syndrome. In 3 of the 4 patients, nocturnal leg cramps resolved with CPAP treatment for OSA, while the fourth patient noted near-resoluti...

INTRODUCTION Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. OBJECTIVE To correlate cephalometric data with the apnea-hypopnea sleep index. METHODS We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disor...

The high prevalence of sleep disorders, particularly obstructive sleep apnea, is well established in children with Down syndrome. However, only a few studies have focused on older children and young adults in this population. Given the presence of sleep disorders and the early emergence of Alzheimer's disease, more work is needed to examine the relationship between sleep and cognition in Down s...

Obstructive sleep apnea syndrome is a common disorder with significant health consequences and is on the rise in consonance with the obesity pandemic. In view of the association between sleep-disordered breathing and pulmonary hypertension as depicted by multiple studies, current clinical practice guidelines categorize obstructive sleep apnea as a risk factor for pulmonary hypertension and reco...
