Sleep apnea severity is higher in African American men, particularly in certain age ranges A new study suggests that obstructive sleep apnea severity is higher in African-American men in certain age ranges, even after controlling for body mass index (BMI). "The results show that in certain age groups, after correcting for other demographic factors, the severity of sleep apnea as measured by the apnea-hypopnea index is higher in African-American males than Caucasian males," said James...

In a study to be presented on February 15 between 8 a.m., and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that women with obstructive sleep apnea (OSA) and cardiac symptoms have a 31 percent incidence of cardiac dysfunction. The use of echocardiograms should be considered in the clinical management of these women. OSA is characterized by abnormal pauses in breathing or instances of...

The severity of sleep disordered breathing and nocturnal hypoxemia independently predict both glycosylated hemoglobin (HbA1c) levels and type 2 diabetes mellitus (T2DM), according to a new study. "Because people with obstructive sleep apnea syndrome (OSAS) are often overweight or obese it has been difficult to interpret earlier studies of the relationship between sleep disordered breathing and metabolic disorders," said Brian Kent, MBBCh, research fellow at St. Vincent's University...

This increased prevalence was primarily driven by a higher incidence of gestational diabetes and early preterm birth."Our findings suggest that moderate to severe sleep-disordered breathing may be associated with adverse pregnancy...

This...

Researchers have demonstrated the effectiveness of a novel treatment that stimulates the nerve that controls the diaphragm to normalize the breathing of patients who suffer from both heart failure and central sleep apnea."Many heart failure patients suffer from central sleep apnea, which a number of studies have shown increases mortality in these patients," said Shahrokh Javaheri, MD, professor emeritus of medicine at the University of Cincinnati and medical director of Sleepcare...

Performing polysomnography (sleep study) prior to pediatric adenotonsillectomy (surgical removal of the tonsils and adenoids) may help identify children at a higher risk of developing postoperative respiratory complications, according to a report in the January issue of Archives of Otolaryngology - Head Neck Surgery, one of the JAMA/Archives journals."Pediatric adenotonsillectomy is a safe outpatient procedure; however, there is a subset of patients who do not meet the criteria for...
