Obstructive Sleep Apnea News and Research

RSS

Obstructive sleep apnea (OSA) is a major heath problem. In the United States, at least 17 million people have moderate to severe OSA, which is characterized by heavy snoring, airway blockage and frequent awakenings during sleep.

Simplified treatment for sleep apnea

Diagnosing and treating obstructive sleep apnea may soon become much less expensive and arduous, thanks to new research showing that a simplified program using experienced nurses, home ambulatory diagnosis and auto-titrating continuous positive airway pressure (CPAP) machines to titrate CPAP pressures is not inferior to the traditional model which relies on specialist physicians and sleep studies.

Video imaging technique provides dynamic view of airway obstruction

A video imaging technique demonstrates that the soft palate, the tissue at the back of the roof of the mouth, is more elongated and angled in patients with obstructive sleep apnea both when they sleep and when they are awake, according to a report in the February issue of Archives of Otolaryngology-Head & Neck Surgery.

Weight loss stops obstructive sleep apnea

For sufferers of obstructive sleep apnea (OSA), a new study shows that losing weight is perhaps the single most effective way to reduce OSA symptoms and associated disorders, according to a new study in the American Journal of Respiratory and Critical Care Medicine , one of the American Thoracic Society's three peer-reviewed journals.

Inflammation may be the link between extreme sleep durations and poor health

A study in the Feb. 1 issue of the journal SLEEP shows that sleep duration is associated with changes in the levels of specific cytokines that are important in regulating inflammation.

Daytime impairments in senior men with obstructive sleep apnea are related to total sleep time

A study in the Feb. 1 issue of the journal SLEEP shows that daytime functional impairments in older men with obstructive sleep apnea (OSA) are largely explained by total sleep time rather than OSA severity.

Links between sleep apnea, stroke and death explained

Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society.

Arousal frequency in heart failure found to be a unique sleep problem

A study in the Jan. 1 issue of the journal Sleep demonstrates that the frequent arousals from sleep that occur in heart failure patients with central sleep apnea (CSA) may reflect the presence of another underlying arousal disorder rather than being a defensive mechanism to terminate apneas.

New research provides a clinical picture of obstructive sleep apnea from over six million hospital admissions

Research in the current issue of the Journal of Clinical Sleep Medicine is the first to show the full clinical picture of comorbid conditions associated with obstructive sleep apnea (OSA), quantify their frequency of occurrence and reveal their possible interrelationships.

Continuous positive airway pressure improves sleeping glucose levels in type 2 diabetics with obstructive sleep apnea

A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine suggests that screening type 2 diabetes patients for obstructive sleep apnea (OSA) and treating those who have OSA with continuous positive airway pressure (CPAP) therapy could improve the management of their hyperglycemia and might favorably influence their long-term prognosis.

Alzheimer's patients with sleep apnea benefit from CPAP treatment - improves cognitive abilities

Continuous positive airway pressure (CPAP) treatment seems to improve cognitive functioning in patients with Alzheimer's disease who also suffer from obstructive sleep apnea, according to the results of a randomized clinical trial conducted at the University of California, San Diego.

Obstructive sleep apnea may be risk factor for sudden cardiac death

After studying the sleep characteristics of nearly 11,000 adults in an overnight sleep laboratory, Mayo Clinic researchers suggest that obstructive sleep apnea (OSA) - and, in particular, the low nighttime oxygen saturation of the blood it causes - may be a risk factor for sudden cardiac death (SCD).

Sleep disorders linked to eye disease

If a good night's sleep helps the brain and body perform better, it's a good guess that sleep problems can cause more than just fatigue.

Sleep disorder linked to eye disease

Research has already suggested that sleep problems can cause more than just tiredness - they have been linked to cardiovascular disease, cerebrovascular disease and metabolic disorders, and are also thought to raise the risk of obesity and diabetes.

Smokers lose ability to smell common odors, increased risk for laryngitis

As Americans prepare for a day without cigarettes and tobacco products as part of the American Cancer Society Great American Smokeout (November 20), new research gives them more reasons to extend that break to a lifetime, according to the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF).

Even minimally symptomatic obstructive sleep apnea increases cardiovascular risk

People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study from the Oxford Centre for Respiratory Medicine in the UK.

People with severe obstructive sleep apnea often have poor diets

A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that unrelated to obesity, people with severe SDBs consume a more unhealthy diet, which may be a factor contributing to greater cardiovascular morbidity and mortality. These findings were most evident among women.
