Stroke victims who have obstructive sleep apnea die sooner than stroke victims who do not have sleep apnea or who have central sleep apnea, according to Swedish researchers, who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Monday, May 19.
The researchers followed 132 stroke patients over 10 years. Twenty-three of those patients had obstructive sleep apnea; 28 of those patients had central sleep apnea. Those with an obstructive apnea-hypopnea index of 15 or greater were 76 percent more likely to die earlier. Those with a lower apnea-hypopnea index of 10 were also at greater risk of early death.

A new study shows both obesity and a large belly appear to increase the risk of developing restless legs syndrome (RLS), a common sleep disorder characterized by an irresistible urge to move and kick your legs.
The research was published in Neurology, the medical journal of the American Academy of Neurology. It is estimated that five-to-10 percent of adults in the United States have RLS and the disorder often has a substantial impact on sleep, daily activities, and quality of life.

A study in the December 1, 2008 issue of the journal Sleep is the first to show that high levels of prenatal smoking exposure strongly modify sleep patterns in preterm neonates, which places infants at a higher risk for developmental difficulties that could persist throughout early and middle childhood.
Results indicate that preterm neonates born to heavy-smoking mothers who smoked more than 10 cigarettes per day displayed disrupted sleep structure and sleep continuity. From 7 p.m. to 8 a.m. they slept almost two hours less than controls who were born to non-smoking mothers, and their sleep was more fragmented. Compared with controls, neonates born to both heavy and low smokers displayed more body movements and, as a result, more disturbed sleep.

DURHAM, NC — Researchers at Duke University Medical Center say they may have figured out why poor sleep does more harm to cardiovascular health in women than in men.
Their study, appearing online in the journal Brain, Behavior and Immunity, found that poor sleep is associated with greater psychological distress and higher levels of biomarkers associated with elevated risk of heart disease and type 2 diabetes. They also found that these associations are significantly stronger in women than in men.

“A sedentary lifestyle increases the propensity to aging-related disease and premature death,” the authors write. “Inactivity may diminish life expectancy not only by predisposing to aging-related diseases but also because it may influence the aging process itself.”

Contrary to even the recommendations of its own section on breastfeeding, the American Academy of Pediatrics (AAP) released an statement from its Task Force on SIDS (sudden infant death syndrome) the Academy of Breastfeeding Medicine has problems accepting. Recommendations that advise against parent-infant bed-sharing and support the generic use of pacifiers imply a “truly astounding triumph of ethnocentric assumptions over commonsense and medical research,” according to Nancy Wight, M.D., president of the Academy of Breastfeeding Medicine.
