CHEST 2011: Embargoed studies highlight new sleep disorder research

Left-Handed People More Likely to Have Sleep Disorder
(#1119044, Wednesday, October 26, 3:00 PM Eastern)

The presence of rhythmic limb movements when sleeping, which may vary in intensity, may be an indicator of periodic limb movement disorder (PLMD). In a study of 100 patients with PMLD, researchers from Toledo, Ohio divided the patients into those who were right-handed and those who were left-handed. Of the 84 right-handed and 16 left-handed patients, 69% of right-handed patients had bilateral limb movements compared with 94% of left-handed patients, irrespective of age, sex, and race. Their findings indicate that left-handed people have significantly higher chances of having bilateral limb movements, indicating the potential for PLMD.

Weight Gain Common After CPAP Therapy
(#1119750, Wednesday, October 26, 7:45 PM Eastern)

Obesity is causally linked to obstructive sleep apnea (OSA). Researchers from Baylor College of Medicine in Houston, Texas studied electronic medical records of veterans diagnosed with OSA and treated with continuous positive airway pressure (CPAP) from January 2005 through May 2005, for baseline data. They examined sleep apnea severity, weight, blood pressure, and blood glucose levels before and after initiation of CPAP. Of the 61 patients studied, including 61 men and three women, with an average age of 63.8 years, the researchers found a trend toward weight gain at 1 year and a statistically significant weight gain at 2 years compared with baseline. This study shows that individuals using CPAP are prone to weight gain due to decreased energy expenditure from a reduction in an active need to breathe.
