The Food and Drug Administration (FDA) has allowed the direct-to-consumer genetics company 23andMe to offer a test for mutations in the BRCA1 and BRCA2 genes, the agency announced today (March 6). The three mutations included in the screen increase the risk of breast and ovarian cancer, and are most common among people of Ashkenazi Jewish decent.
New research from The University of Texas at Dallas supports the growing consensus that pain begins differently for men and women at the cellular level. Ted Price BS’97, Salim Megat and their colleagues in the Pain Neurobiology Research Group recently found that a specific manipulation of receptors in the nervous system for the neurotransmitter dopamine impairs chronic pain in male mice, but has no effect on females.
Diabetes is a more diverse disease than medicine currently acknowledges – and treatments could be improved by splitting the disease into more types, according to a new study. The two “types” of the disease are not precise enough – and the adult-onset varieties of the disease should be split into five distinct categories, according to the paper in The Lancet Diabetes and Endocrinology.
In one of the first looks at the urinary virome, researchers find hundreds of viruses, most of which have never been sequenced before.
A new cancer treatment experiment at Stanford University that used immune-stimulators to target tumors in mice had remarkably encouraging results.
Patients without calcium buildup in the coronary arteries had significantly lower risk of future heart attack or stroke despite other high risk factors such as diabetes, high blood pressure, or bad cholesterol levels, new research from UT Southwestern cardiologists shows.
A core assumption in the study of disease-causing genes has been that they are clustered in molecular pathways directly connected to the disease. But work by a group of researchers at the Stanford University School of Medicine suggests otherwise.
"Gonorrhea cases have continued to climb as STD rates have recently spiked across the nation. But doctors have had one less drug in their toolkit over the last decade, since the bacteria started to develop resistance to a key antibiotic."
"An innovative “bio-bag” system developed by a team of doctors from the Children’s Hospital of Philadelphia (CHOP) mimics the environment of a mother’s womb and could provide the physiologic support premature babies need to properly develop."
"Despite the pervasiveness of diagnostic errors and the risk for serious patient harm, diagnostic errors have been largely unappreciated within the quality and patient safety movements in health care. Without a dedicated focus on improving diagnosis, these errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity"
