Hope for a heart attack warning test and a baldness cure
By Kim Painter
Heart attack test: Some people really are heart attacks waiting to happen — but go unnoticed and untreated by their doctors. That could change someday with a blood test that detects cells that flake off damaged blood vessels before a heart attack. Researchers don’t yet know whether the cells appear days or weeks before a heart attack, but they do know “if you have them, you have trouble lurking,” one scientist told The Los Angeles Times.
Baldness cure? Scientists may be closer to a so-far elusive goal: helping bald men grow hair again. Working with both mice and men, researchers have identified a protein that inhibits hair growth. Drugs that could interfere with that protein already are in development for other uses.
Black women and breast cancer: Black women in the United States die of breast cancer at higher rates than white women — often because of uneven access to medical care. But that’s not the whole story, say researchers who found the higher rates in 13 of 24 cities. For reasons that are poorly understood, black women also are prone to breast cancer at younger ages and in more severe forms.
Sinus treatments: Antibiotics are rarely the answer for sinus infections, say new guidelines from infectious disease doctors. That’s because antibiotics treat bacteria and most sinus infections are caused by viruses. The group also says antihistamines and decongestants don’t help, but that nasal steroids and nasal irrigation are useful for some patients.
Today’s talker: A video of a group of men pushing a woman in a wheelchair off a bridge has become an Internet sensation — and, believe it or not, it’s a feel-good story. The paralyzed woman, Christine Rougoor, was among a bungee-jumping group of people with disabilities enjoying an adventure trip. “I’m used to sitting upright all the time so the first two seconds sideways really made my stomach turn,” Rougoor tells CNN. “It was amazing!” She adds: “The minute I got back, I begged them to push me back over!”
