Heart disease is a leading cause of death for women, and yet women are more likely than men to dismiss pain or symptoms of heart problems, and to delay seeking medical help — a “dangerous game” that experts say may have serious health implications.
Though heart symptoms are similar for both men and women, the way that people perceive their symptoms and the point at which they are moved to seek medical help can vary widely.
Women may be more likely than men to exhibit an ‘optimism bias’ — a cognitive bias that causes them to believe they are less at risk for negative outcomes than they actually are — than men, which can keep them from seeking medical assistance and could worsen their condition, according to new research from the Harvard School of Public Health.
“The main danger is that when someone comes to the hospital with a more severe or advanced stage of heart disease, there are simply fewer treatment options available,” epidemiologist Dr. Catherine Kreatsoulas, Heart and Stroke Foundation research fellow at the Harvard School of Public Health and lead author of the study, said in a statement.

From dry skin to mosquito bites, there are a million little reasons why we itch. But sometimes, scratching an itch can make you feel, well, itchier — and a group of scientists has a possible explanation for why this happens.
On Wednesday, researchers at Washington University School of Medicine in St. Louis published a study which found that scratching an itch can cause minor pain, leading the brain to release serotonin — the “happy” chemical that helps regulate mood — which can sometimes make an itch feel more intense.
“The problem is that when the brain gets those pain signals, it responds by producing the neurotransmitter serotonin to help control that pain,” senior investigator Zhou-Feng Chen, PhD, who’s also the director of Washington University’s Center for the Study of Itch, explained in a written statement. “But as serotonin spreads from the brain into the spinal cord, we found the chemical can ‘jump the tracks,’ moving from pain-sensing neurons to nerve cells that influence itch intensity.”

Scientists involved with the study bred a strain of genetically engineered mice that lacked serotonin. When injected with itch-causing chemicals, these mice didn’t scratch as much as mice with the —> Read More Here
