April 4, 2012 - Pregnancy can increase a woman's chance of dying from a heart attack. Researchers from the University of Southern California found heart attacks in pregnant women are three times more fatal than in a woman who isn't pregnant. Seven percent of pregnant women die from them. The study's lead researcher says doctors need to be more aware that heart attacks during pregnancy differ from a typical heart attack in their causes and treatments.
Also, according to the Los Angeles Times, scientists may have discovered a new way to fight cancer cells. Researchers from Stanford University found that a certain anti-body can slow the growth of tumors. Normally, a protein called CD 47 prevents immune cells from attacking the tumor. Now, researchers say an antibody can block that protein, helping the immune system to try to destroy the cancer cells. The study found the process, which was tested on mice, worked on all kinds of cancers. Now, they have to figure out if it's safe for humans.
