Study Objectives: We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can the new approaches provide more information on the structure of sleep-stage transitions? (ii) How does sleep fragmentation in patients with sleep apnea affect the structure of sleepstage transitions? Design: We analyze hypnograms and compar...

OBJECTIVE To assess the relation between medications prescribed for chronic pain and sleep apnea. DESIGN An observational study of chronic pain patients on opioid therapy who received overnight polysomnographies. Generalized linear models determined whether a dose relation exists between methadone, nonmethadone opioids, and benzodiazepines and the indices measuring sleep apnea. SETTING A pr...

STUDY OBJECTIVE To evaluate the tolerability and to find predictors of treatment success for an individually adjusted, one-piece mandibular advancement device in patients with snoring and obstructive sleep apnea. DESIGN Prospective study. SETTING Departments of Respiratory Medicine and Orthodontics, Umeå University. PATIENTS Six hundred nineteen of 630 patients (98%), who consecutively re...

Introduction:The overlap syndrome, consisting ofobstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructvie pulmonary disease (COPD) is a major problem in COPD patients. OSHAS corresponds to the likelihood of systemic hypertension.The present study was aimed to evaluate the association between apnea-hypopnea index and diastolic blood presssure (DBP) in overlap  patients. Materials...

In this study we evaluated the incidence and severity of obstructive sleep apnea and Obstructive sleep apnea syndrome in patients with thromboangiitis obliterans for reduction of crisis. In 40 patients with Buerger's disease daily sleepiness and risk of Obstructive sleep apnea were evaluated using the Epworth sleeping scale (ESS) and the Stop-Bang score. An Apnea-link device was used for evalua...

Sleep apnea is a common chronic disease that is associated with coronary heart disease, stroke, heart failure and mortality, although the ability of sleep apnea treatment to reduce cardiovascular morbidity and mortality has not been demonstrated. In contrast to patients seeking treatment in sleep disorders centers, as many as half of individuals with moderate to severe sleep apnea in the genera...

INTRODUCTION Obstructive sleep apnea is defined as repetitive (≥5/hour) partial or complete cessation of breathing during sleep. Whereas obstructive sleep apnea is often considered to be associated with sexual problems in men, studies concerning effects of obstructive sleep apnea on female sexual function and distress are sparse. AIM To investigate sexual dysfunction and sexual distress in fe...

BACKGROUND Sleep apnea is common and associated with poor outcome in severe chronic kidney disease, but validated screening tools are not available. Our objectives were to determine the prevalence of sleep apnea in this population, to assess the validity of screening for sleep apnea using an ApneaLink device and to investigate the relationship of sleep apnea to; symptoms, spirometry and body wa...

OBJECTIVE The aim of this study is to compare patients treated with pharyngoplasty and those treated with palatoplasty for velopharyngeal insufficiency to establish what surgical procedure poses the highest risk for developing sleep apnea. The hypothesis tested in this study is that the incidence of obstructive sleep apnea syndrome associated with pharyngoplasty is greater than that associated ...
