CCBAR member, Natalia Gavrilova, PhD, participated in the international REVES conference on health expectancy held May 25-27, 2011 in Paris, France. The focus of the 2011 REVES conference was "Are sex differences in health expectancy a social issue?" In their presentations, participants explored possible causes of the apparent paradox of the longer female life span, which is accompanied by worse health as compared to males, in addition to a breadth of topics related to sex differences in health expectancy. Materials for the 2011 REVES meeting will appear soon on the REVES website. For materials from previous REVES meetings, please visit http://reves.site.ined.fr/en/REVES_meetings/previous_meetings/.
The next Chicago Core on Biomeasures in Population-Based Health and Aging Research Conference will be held in Chicago this fall. The focus of the 2011 conference will be Biosocial Approaches to the Study of Urban Health and Aging. More information will follow in the June CCBAR Newsletter.

A new method to measure the amount of the stress hormone cortisol found in the body over the long term could lead to new research avenues to study the development of common conditions, such as heart disease, diabetes and depression. Researchers have found that hair can be used to create a retrospective timeline of exposure to cortisol. Cortisol is implicated in the development of many common conditions and this new technique could allow us to study its role better.
• Blood test markers link polycystic ovary syndrome with cardiovascular risk
A new study shows that women with polycystic ovary syndrome (PCOS) show higher levels of blood markers associated with cardiovascular disease (CVD) than control groups. These markers show up during a woman's earlier life, but might indicate a greater CVD risk in later life.
• Gene for Alzheimer's Risk May Affect Brain Early
Young adults who carry a so-called Alzheimer's risk gene show disruption in their brains as early as their 20s, according to new research.
• Simple fitness test could predict long-term risk for heart attack, stroke in ...
In two separate studies, researchers have found that how fast a middle-age person can run a mile can help predict the risk of dying of heart attack or stroke decades later for men and could be an early indicator of cardiovascular disease for women.
• Super-sticky 'ultra-bad' cholesterol revealed in people at high risk of heart...
Scientists have discovered why a newly found form of cholesterol seems to be 'ultra-bad', leading to increased risk of heart disease. The discovery could lead to new treatments to prevent heart disease particularly in people with type 2 diabetes and the elderly.
• Waist size predicts heart-disease death better than weight
Doctors have long known that obesity increases a person's risk of heart disease, but in recent years the picture has grown more complicated.

5-minute screen identifies subtle signs of autism in 1-year olds
A five-minute checklist that parents can fill out in pediatrician waiting rooms may someday help in the early diagnosis of autism spectrum disorder (ASD), according to a study funded by the National Institutes of Health. Published today in the Journal of Pediatrics, the study's design also provides a model for developing a network of pediatricians to adopt such a change to their practice.
Tired neurons caught nodding off in sleep-deprived rats
A new study in rats is shedding light on how sleep-deprived lifestyles might impair functioning without people realizing it. The more rats are sleep-deprived, the more some of their neurons take catnaps -- with consequent declines in task performance. Even though the animals are awake and active, brainwave measures reveal that scattered groups of neurons in the thinking part of their brain, or cortex, are briefly falling asleep, scientists funded by the National Institutes of Health have discovered.
Vitamin E helps diminish a type of fatty liver disease in children
A specific form of vitamin E improved the most severe form of fatty liver disease in some children, according to a study funded by the National Institutes of Health. Results appear in the April 27 issue of the Journal of the American Medical Association. A previous study found vitamin E effective in some adults with the disease.
