New research provides insight into how changes that occur with age may predispose breast tissue cells to becoming cancerous. Specifically, the study demonstrates that regions in the genome where DNA methylation changes occur with age are particularly sensitive to disruption in cancer. This new data provides insight into how certain molecular changes with age in normal breast tissue itself may contribute to breast cancer risk.
Patients in nursing homes that provided a high-dose flu vaccine were significantly less likely than residents in standard-dose homes to go to the hospital during flu season, according to a new study.
The center of a public health debate is whether parents should have their children vaccinated. Tara Smith, Ph.D., professor of epidemiology at Kent State University's College of Public Health, challenges statements made by influential individuals who oppose the widespread use of vaccines, and she calls upon her colleagues in the scientific community to speak out to promote vaccination.
A new test is the best-to-date in differentiating Zika virus infections from infections caused by similar viruses. The assay is currently in the licensing process and researchers hope it will be available to the medical community soon.
Giving children high doses of vitamin D doesn't appear to reduce the winter sniffles, a new study has found.
A study involving 65 people who live in and around São José do Rio Preto (São Paulo State, Brazil), where dengue is endemic and there was a particularly rapid outbreak of Zika during the 2016 epidemic, show that prior dengue infection in human beings infected by Zika does not necessarily lead to a worse illness.
A first-of-its-kind effort to examine the ecological drivers of rural poverty combines economic, ecological and epidemiological models. The lessons learned could inform interventions to lift people out of poverty.
A lack of evidence that bats are key reservoirs of human disease has not prevented their vilification or efforts to exterminate bat colonies where threats are presumed to lurk. 'The fact is that they provide important ecosystem services...and we want them around,' says Tony Goldberg, a University of Wisconsin-Madison epidemiologist and virus hunter. 'But bats are also increasingly acknowledged as hosts of medically significant viruses. I have mixed feelings about that.'
People who work long hours have an increased risk of developing an irregular heart rhythm known as atrial fibrillation, according to a study of nearly 85,500 men and women published in the European Heart Journal.
Information from nearly 4,000 US residents indicates that only 61 percent of all gun owners and 14 percent of non-owners who live with a firearm owner have received any formal gun training, percentages largely unchanged since 1994, according to a study from the University of Washington.
