CCBAR Director, Stacy Lindau, took part in the meeting of the Scientific Advisory Board for the HRS-harmonized population-based study TILDA in Dublin, Ireland. TILDA Wave I data are available for request via the Irish Social Sciences Data Archive (ISSDA) http://www.tcd.ie/tilda/researchers/access/. More information about TILDA data availability can be found on TILDA website. During her visit to Dublin, Dr. Lindau toured the Liberties neighborhood with Irish colleagues and gave a lecture to health researchers and community leaders in the Liberties about MAPSCorps, an asset mapping program that engages youth and older adults from low income communities in gathering community resource data that are used to link people to resources for self-care and disease management.
Natalia Gavrilova participated in the Network on Biological Risk annual meeting held on May 2, 2012 in San Francisco, CA. This meeting was an important event for researchers collecting biomarkers in population-based settings. The first part of the meeting was devoted to various aspects of dried blood spot collection and analysis. Additional talks included Elissa Epel on telomeres and Diane Lauderdale on sleep measurement. The meeting agenda can be found on the Biomarker Network website. Natalia Gavrilova also participated in the 2012 annual meeting of the Population Association of America in San Francisco where she gave a presentation on the link between month of birth and exceptional longevity using the within-family approach. This year's meeting had many interesting presentations on biomeasures in population studies including one by Laura Blue from Princeton University on body weight, weight change and mortality risk. She estimated the relationship between body mass index (BMI) and mortality among adults aged 50-79 using data from five longitudinal surveys in a different high- or middle-income country: Australia, Costa Rica, England, Taiwan, and the USA. In all five surveys, the lowest risk of mortality was observed for "overweight" levels of BMI (25-30 mg/m2). Moreover, study of weight changes over time showed that weight gain was associated with lower mortality while weight loss was linked to higher mortality. These results raise new questions about healthy weight in aging.

To celebrate the 10th anniversary of the completion of the first

NIH study
finds sigmoidoscopy reduces colorectal cancer rates
Flexible sigmoidoscopy, a screening test for colorectal cancer that is
less invasive and has fewer side effects than colonoscopy, is effective
in reducing the rates of new cases and deaths due to colorectal cancer,
according to research sponsored by the National Cancer Institute, part
of the National Institutes of Health. In a study that spanned almost 20
years, researchers found that overall colorectal cancer mortality
(deaths) was reduced by 26 percent and incidence (new cases) was
reduced by 21 percent as a result of screening with sigmoidoscopy.
These results appeared online, ahead of print, on May 21, 2012, in the
New England Journal of Medicine, and were presented at Digestive
Disease Week, a scientific conference.

variant of ApoE damages the blood vessels that feed the brain.
Awake
mental replay of past experiences critical for learning
Awake mental replay of past experiences is essential for making

and acting on, past experience by selectively suppressing replay --
encoded as split-second bursts of neuronal activity in the memory hubs
of rats performing a maze task.

Two new studies have found that large structural abnormalities in
chromosomes, some of which have been associated with increased risk of
cancer, can be detected in a small fraction of people without a prior
history of cancer. The studies found that these alterations in
chromosomes appear to increase with age, particularly after the age of
50, and may be associated with an increased risk for cancer. These
studies were conducted by two consortia, one led by scientists at the
National Cancer Institute (NCI), and one by Gene Environment
Association Studies (GENEVA) which is sponsored by the National Human
Genome Research Institute (NHGRI). NCI and NHGRI are both parts of the
National Institutes of Health.
