Obstructive Sleep Apnea News and Research RSS Feed - Obstructive Sleep Apnea News and Research

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. OSA is one of the major causes of severe daytime sleepiness, and is a major risk factor for automobile accidents and workplace injuries. If left untreated, OSA has been implicated as a major risk factor for cardiovascular disease, including hypertension and heart failure, as well as stroke.

OSA is caused by collapse of the upper airway during sleep, and treatment for the disorder is based upon therapies that keep the airway open. The most common treatment for OSA is continuous positive airway pressure (CPAP). At least 50% of patients with OSA find it difficult or impossible to use CPAP and are therefore candidates for surgery. However, current surgical options for these patients are very limited, particularly related to the tongue base.

New, implantable device offers promise for patients with OSA

Since the 1980s, continuous positive airway pressure (CPAP) - in which positive pressure is pushed through the nasal airways to help users breathe while sleeping - has been by far the most widely used treatment for obstructive sleep apnea (OSA). [More]

When people think of sleep disorders such as obstructive sleep apnea (OSA), images of middle aged adults likely come to mind. However, a recent study by Gillette Children's Specialty Healthcare sheds light on another population of people who are affected by the disorder: children who have cerebral palsy (CP). [More]
OSA patients may have 1.57 times more MACCE risk afer unplanned revascularization

OSA patients may have 1.57 times more MACCE risk afer unplanned revascularization

In an ongoing prospective study involving 1,311 patients from five nations, researchers found that untreated obstructive sleep apnea (OSA) was associated with increased risk of a Major Adverse Cardiac and Cerebrovascular Event (MACCE) -- cardiovascular death, non-fatal myocardial infarction (heart attack), non-fatal stroke, and unplanned revascularization such as heart bypass surgery and angioplasty.

Severe obstructive sleep apnea may increase likelihood of cognitive deficits in children

Sleep assessments in young children showed that, in the context of habitual snoring and enlarged tonsils and adenoids, moderate to severe obstructive sleep apnea increased the likelihood and magnitude of cognitive deficits. [More]

Myocardial fibrosis linked to adverse cardiovascular outcomes in OSA patients

Myocardial fibrosis could be a future therapeutic target after researchers found it correlated with adverse cardiovascular outcomes in patients with obstructive sleep apnoea (OSA) referred for cardiac magnetic resonance (CMR). [More]

Crash risk higher among truck drivers not adhering to sleep apnea treatment

Truck drivers who have obstructive sleep apnea and who do not attempt to adhere to a mandated treatment program have a fivefold increase in the risk of a severe crash, according to a new study co-authored by Virginia Tech Transportation Institute researchers and featured in the March 21 online edition of the journal Sleep.

People with type 2 diabetes, OSA may not experience improved glycemic control with CPAP

People with type 2 diabetes and obstructive sleep apnea (OSA) may not experience improved glycemic control by using continuous positive airway pressure, or CPAP, as some studies have suggested, according to the results of a randomized, controlled trial published online ahead of print in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
