Got Osteoporosis? Urine Luck.

1 Urine Test for Bone Loss Better Than X-Rays

Scientists from Arizona State University and NASA have developed a technique for diagnosing osteoporosis that detects bone loss using a simple urine test in place of X-rays. The new procedure, as reported in the Proceedings of the National Academy of Sciences journal, involves measuring calcium isotopes in the urine through mass spectrometry to calculate the bones' mineral balance, which indicates bone increase or decrease. Inactivity produces bone loss, and when volunteers who were assigned to prolonged bed rest were tested using this method, bone loss was detected within one week, making the urine test much faster than X-rays, which only reveal bone damage already done, as well as safer and free of radiation exposure.

Risks Outweigh Benefits

2 HRT Not Recommended to Prevent Heart Disease

Healthy women who've already gone through menopause shouldn't take hormone replacement therapy (HRT) medication for the prevention of heart disease, dementia and bone loss, advises the U.S. Preventive Services Task Force. The recommendation is published in Annals of Internal Medicine. Los Angeles Times reports that the decision may have detractors among doctors who think that the risks of HRT for menopausal women have been overblown. While the task force recommendation doesn't apply to women who use HRT to reduce hot flashes, vaginal dryness and night sweats during menopause, a report by the federal Agency for Healthcare Research and Quality will soon address whether this group of women should use HRT.

Laugh and Live

3 Outgoing People May Live Longer

Outgoing, easygoing and optimistic people may live longer, suggest researchers. The study, which is part of the Albert Einstein College of Medicine's Longevity Genes Project, was published in Aging. Researchers found that most of the centenarians in the study considered laughter an important part of their lives. The centenarians were also likely to be easygoing, outgoing and optimistic, report researchers. However, researchers point out that personality may change between ages 70 and 100, so it's not known whether the centenarians maintained their personality traits throughout their lives.

No Alias for HFCS

4 Corn Syrup Won't Be Renamed Corn Sugar

High fructose corn syrup (HFCS) won't be renamed "corn sugar," ruled the FDA. In 2010, the Corn Refiners Association requested that the FDA allow them to call HFCS by the sweeter-sounding name "corn sugar." HFCS costs less than regular sugar, and has been in wide use for decades, but has recently become unpopular due to questions over whether it contributes to obesity. NPR reports that the FDA is sticking with the common understanding of the terms "sugar" and "syrup" as defined by the dictionary. HFCS is a syrup, not a crystal like sugar. In addition, a product known as corn sugar (dextrose) has been on the market for 30 years, and is a substitute for people who can't tolerate regular sugar.
