CHEST 2011: Embargoed studies highlight new sleep disorder research
Date:10/23/2011

nts who carry more than one child at a time. This study, which included 100 women between the ages of 18 and 86 years who had no pregnancies or up to 12 pregnancies, took place between December 2010 and April 2011. The study showed a higher prevalence of rapid eye movement (REM)-related OSA in women pregnant with two, three, or more babies than in women who either were not pregnant or carried only one child at a time. They attributed the REM-related OSA to structural and/or functional changes in the upper airway induced by repetitive exposure to pregnancy hormones. Identifying a tendency to carry multiples allows for earlier diagnosis and intervention in this group of women, possibly preventing the long-term OSA aftereffects.

Sleep Disorders Common Among Soldiers With Brain Injury, PTSD
(#1119758, Monday, October 24, 7:30 PM Eastern)

Soldiers with combat-related injuries, including traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD), experience a high incidence of sleep disorders. Researchers from Walter Reed Army Medical Center in Washington, DC, studied 261 patients including 135 with PTSD, 116 of whom had a TBI, and 66 with both conditions. Of these patients (90.4% men, mean age 35 years), soldiers with combat-related TBI and PTSD were found to have high rates of disordered sleep. Of those with TBI blunt trauma, more experienced obstructive sleep apnea (OSA) (54.3% vs 25.9%, p=0.003), while, of those with blast injuries, more experienced insomnia (63.0% vs 40.0%, p=0.022). Overall, insomnia rates were similar among all patients with PTSD; however, PTSD appears to predispose soldiers to OSA. An increased awareness of the prevalence of sleep disorders is important in order for adequate treatment to be provided, especially beyond soldiers' military commitment.
