Using a recently developed biomarker of aging known as an epigenetic clock, UCLA researchers working closely with a German team of investigators have found for the first time that obesity greatly accelerates aging of the liver. This finding could explain the early onset of many age-related diseases, including liver cancer, in people who are obese. (more…)

Decoding dengue and West Nile: Researchers take steps toward control of growing public health problems
ANN ARBOR — Dengue fever and West Nile fever are mosquito-borne diseases that affect hundreds of millions of people worldwide each year, but there is no vaccine against either of the related viruses.
A team of scientists at the University of Michigan and Purdue University has discovered a key aspect both to how the viruses replicate in the cells of their host and how they manipulate the immune system as they spread. (more…)
ANN ARBOR — Only about a third of Americans ages 65 and older are fully able to take care of themselves and go about their daily lives completely independently, according to a new study published online in the American Journal of Public Health.
Understanding that there are different ways older adults adapt to disability is a big step in developing public health policies that maximize the quality of life for all older Americans, said the study’s lead author, Vicki Freedman, a research professor at the University of Michigan Institute for Social Research.

COLLEGE PARK, Md. – Angelina Jolie heightened awareness about breast cancer when she announced in a New York Times op-ed that she had undergone a preventive double mastectomy. But a new study led by researchers in the University of Maryland School of Public Health and the Johns Hopkins School of Public Health reveals that widespread awareness of Jolie’s story did not translate into increased understanding of breast cancer risk.
The survey of more than 2,500 Americans found that three out of four were aware of Jolie’s story, but fewer than 10 percent of those could correctly answer questions about the BRCA gene mutation that Jolie carries and the typical person’s risk of developing breast cancer. Though very rare, women with harmful mutations in either of two genes, BRCA1 and BRCA2, have a risk of breast cancer that is about five times the normal risk, and a risk of ovarian cancer that is about ten to thirty times normal. The study is published on December 19, 2013 in Genetics in Medicine. (more…)
Bullying because of perceived sexual orientation is prevalent among school-aged youths, according to a study led by Donald Patrick, professor of health services at the UW School of Public Health. The study was published online May 16 in the American Journal of Public Health.
The research team analyzed responses collected in a 2010 Washington state survey of more than 24,000 public school students in grades eight through 12. The study found that 14 percent, 11 percent and 9 percent of male students in grades 8, 10, and 12 respectively reported being bullied because of perceived sexual orientation. For female students in those grades, the numbers were 11 percent, 10 percent and 6 percent respectively. (more…)
Clean Syringes Often Unavailable in St. Petersburg, YSPH Research Finds
Russia’s HIV epidemic is among the fastest growing in the world and injection drug users who often share needles and other supplies are hardest hit. This occurs even though pharmacies are a legal source for clean syringes and can sell them without restriction.
A recent study led by the Yale School of Public Health and St. Petersburg State University mapped the city’s 965 pharmacies and compared their locations and density to HIV prevalence at the district level. (more…)
