A late-breaking abstract (LBA 8) that will be presented at noon Pacific Time as an oral presentation demonstrates that people with mild to moderate obstructive sleep apnea may experience a clinically relevant and statistically significant improvement in functional status at eight weeks on active continuous positive airway pressure (CPAP) therapy.
The study analyses involved 113 people who were randomized to an active CPAP therapy treatment group, and 110 people who were randomized to a sham treatment group. The adjusted group difference in mean changes from baseline to week eight of treatment was 0.95 points on the Functional Outcomes of Sleep Questionnaire total score.
You can read the abstract in the final program.

Improving CPAP Compliance for Sleep Apnea
Two studies being presented as posters later this morning address issues related to patient compliance with continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea.
One study (#0582) shows that some problem-solving and coping styles contribute to successful CPAP use. These include seeking advice and information from other people, and creating goal-oriented schedules.
Another study (#0576) shows that a spouse or cohabiting partner’s involvement can help improve CPAP compliance. The most effective methods of helping were “bilateral tactics,” which involve a collaborative effort to work together.

Benefits of Receiving Care at AASM-Accredited Sleep Centers
Two studies being presented as poster presentations today at SLEEP 2008 describe benefits of receiving medical care from American Academy of Sleep Medicine-accredited sleep centers and from board certified sleep specialists.
One ongoing study (ID# 1069) of 243 patients at four participating sleep centers found that patients cared for by AASM-accredited centers and board-certified physicians received better education than patients cared for by non-accredited centers and non-certified physicians.
One-hundred percent of study subjects at AASM-accredited centers reported receiving adequate education about obstructive sleep apnea (OSA). At non-accredited sites, 83.5 percent of study subjects reported receiving adequate education about OSA.
AASM Standards for Accreditation require that accredited sleep centers have on staff at least one board-certified sleep specialist. Initial results of this study were published in the Journal of Clinical Sleep Medicine in 2006.
Another study (ID# 1073) of 55 patients shows that access to specialized services with close follow up in an AASM-accredited sleep center can make a significant difference in treatment success. Each of the patients had a high risk of failure to comply with continuous positive airway pressure therapy (CPAP) for OSA. Sixty-one percent of the patients became compliant and were followed up for six months.

Sleep Loss, Alzheimer’s and Sleep Apnea
A study (ID# 0291) being presented as an oral presentation this morning at SLEEP 2008 evaluated 52 older adults who have both Alzheimer’s disease (AD) and obstructive sleep apnea (OSA).
When the study subjects were treated with continuous positive airway pressure (CPAP) therapy, the resulting increase in total sleep time was significantly associated with improvements in neurocognitive testing.
No other variables, including changes in oxygenation, were significant. This implies that the cognitive impairment associated with OSA in AD patients may result from short sleep time.
The American Academy of Sleep Medicine reports that the steepest prevalence increase for OSA is in the transition from middle-aged to older-aged adults. According to the National Institute on Aging, up to 4.5 million Americans suffer from AD, which usually begins after the age of 60.

U.S. Veterans Battle Insomnia after Returning from Iraq
A study (ID# 0697) being presented as an oral presentation this morning at SLEEP 2008 shows that insomnia is a significant problem for combat-exposed U.S. soldiers returning from Iraq.
The study examined the sleep of 14 Operation Iraqi Freedom veterans who have post-deployment adjustment disorders. They were compared with 14 people who have primary insomnia and 14 good sleepers.
The veterans reported much worse sleep quality and sleep efficiency, increased time to fall asleep and wake time after falling asleep, and more nocturnal awakenings than good sleepers. Sleep measures of the veterans were similar to those of the people with primary insomnia.
The veterans also had more severe disruptive nocturnal behaviors than both good sleepers and people with primary insomnia.
A study (ID# 0736) that was presented yesterday as a poster presentation shows that U.S. veterans of the war in Iraq who struggle with insomnia may prefer treatment that combines medications with non-pharmacological approaches such as relaxation therapy. Veterans also preferred receiving therapy through MP3 files and the Internet.
Another study (ID# 0556) presented yesterday as a poster presentation reports that black veterans are significantly less likely than white or Asian veterans to adhere to continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea.

Exhibit Hall to be a Highlight of SLEEP 2008
In addition to its scientific program of research presentations and educational sessions, SLEEP 2008 features an exhibit hall with booth displays from more than 150 pharmaceutical companies, medical equipment manufacturers, publishers, software distributors and educational providers.
Exhibitors at SLEEP 2008 will showcase products such as sleep medications, diagnostic equipment used for sleep studies, and therapeutic devices such as continuous positive airway pressure (CPAP) units and masks.
Of particular interest this year will be unattended portable monitoring systems that can be used for home sleep testing. A recent decision by the Centers for Medicare & Medicaid Services approved the use of home sleep testing for the diagnosis of obstructive sleep apnea in Medicare beneficiaries.
Many of the products on display are used in the diagnosis and treatment of people with sleep disorders. It is estimated that 50 million to 70 million people in the U.S. suffer from a chronic sleep disorder, and the majority of them have not been diagnosed or treated. There are 81 sleep disorders classified in the International Classification of Sleep Disorders, 2nd Edition (American Academy of Sleep Medicine, 2005).
The SLEEP 2008 exhibit hall will be open to registered attendees from 10 a.m. to 4 p.m. on Monday, June 9, and Tuesday, June 10; and from 10 a.m. to 2 p.m. on Wednesday, June 11.
