Canada study revives mammogram debate. A new study published this month in the medical journal BMJ states that receiving a mammogram between ages 40 and 59 did not have a lower chance of dying of breast cancer more than a physical exam. The report said 22 percent of invasive cancer was over-diagnosed. That means the tumor may be too small to be life threatening or even create symptoms. In 2009, the U.S. Preventive Services Task Force faced criticism after it recommended that women get mammograms starting at age 50. That went against what the American Cancer Society has recommended, which is annual mammograms beginning at 40.
ADA: Fluoride before age 2. The American Dental Association recommends that children start using toothpaste with fluoride to prevent cavities as soon as they get their first tooth. The previous recommendation was to start fluoride toothpaste at age 2. Dentists say parents should use a smear of toothpaste for children younger than 3 and a pea-sized amount for children older than 3.
Cold weather linked to strokes. A study by researchers at Duke and Harvard universities showed that there is a link between climate trends and the risk of suffering a stroke. When the weather is cold, humid or there are temperature swings, more people ended up in the hospital. The warmer it got, the risk fell by 3 percent for every 5 degrees. Researchers said blood vessels constrict in cold weather, which can raise blood pressure. It also can trigger a stress reaction in the body.
No antibiotic chicken at Chik-fil-a. Chick-fil-A announced last week that they will be using antibiotic-free chicken within five years. There has been an awareness about the problem of antibiotic resistance and the U.S. Food and Drug Administration has said antibiotics in livestock contribute to the rise of harmful bacteria. Chik-fil-A officials want suppliers to collaborate with the U.S. Department of Agriculture to make sure chickens don’t receive antibiotics.
