BACKGROUND Prospective data suggest that sleep-disordered breathing enhances risk for incident and recurrent cardiovascular disease (CVD). However, a reverse causal pathway whereby incident CVD causes or worsens sleep-disordered breathing has not been studied. METHODS AND RESULTS A total of 2721 Sleep Heart Health Study participants (mean age 62, standard deviation=10 years; 57% women; 23% mi...

OBJECTIVES to describe the frequency of sleep apnea in patients with acromegaly;to identify the proportion of candidates for treatment with positive airway pressure;to report our experience with the positive pressure titration process in acromegaly patients. METHODS A cross-sectional study that included the acromegaly cohort at the Centro Medico Nacional "20 de Noviembre" in Mexico City (n=44...

sleep apnea, and particularly obstructive sleep apnea, is a common disorder that is characterized by a repetitive, partial or complete cessation of air flow, associated with oxyhemoglobin desaturation and an increased effort to breath. in recent years, orthodontists have been interested and involved in the management of this disorder since it has been shown that oral appliance therapy can be an...

introduction: the berlin questionnaire (bq) is a common tool to screen for obstructive sleep apnea (osa) in the general population, but its application in the clinical sleep setting is still challenging. the aim of this study was to determine the specificity and sensitivity of the bq compared to the apnea-hypopnea index obtained from polysomnography recordings obtained from a sleep clinic in ir...

What We Found § Though far fewer than the 1995 study found, 4.7% of commercial drivers in the study were found to have severe sleep apnea. Another 5.8% had moderate sleep apnea and 17.6% has mild sleep apnea. § Prevalence of moderate to severe sleep apnea is twice as high among CDL holders no longer currently employed as drivers, suggesting that the industry may be losing valuable drivers becau...

To the Editor: The recent update of the report “Practice Guidelines for the Perioperative Management of Patients with Obstructive Sleep Apnea” by the American Society of Anesthesiologists Task Force on Perioperative Management of Patients with Obstructive Sleep Apnea did not provide any new recommendations.1 Like its predecessor, the updated version includes “table 2,” a scoring system for peri...

We hypothesized that reductions in arterial PCO2 (PaCO2) below the apnea threshold play a key role in the pathogenesis of idiopathic central sleep apnea syndrome (ICSAS). If so, we reasoned that raising PaCO2 would abolish apneas in these patients. Accordingly, patients with ICSAS were studied overnight on four occasions during which the fraction of end-tidal CO2 and transcutaneous PCO2 were me...

Obstructive Sleep Apnea Syndrome (OSAS) has emerged as a global public health problem. OSAS is largely recognized as a factor for increased risk of vehicular related accidents for those diagnosed and undiagnosed. This article serves as a country report that reviews current and potential policies regarding OSAS induced drowsy driving in both Japan and the United States of America. In addition to...

Snoring can occur alone or it may be the presenting feature of Obstructive Sleep Apnea and other common chronic conditions. In our study, we aimed to estimate the prevalence and correlates of snoring in adolescent students in Tehran, Iran. A cross-sectional study was designed and students were selected from 20 secondary and high schools, in 5 different zones in Tehran in order to have a represe...
