Doctors may one day check on your heart rate and respiration without an office visit. University of Florida electrical and computer engineering experts have devised a small antenna system that sends signals right to a laptop computer. The tiny tabletop system uses a miniaturized dopplar radar that bounces waves off a patient sitting nearby, no cuffs or clips required. The high-frequency waves can measure the rate of breathing and the motion of the heart. The information is then sent via the internet, or even a cell phone, for a doctor to evaluate.
It is not unusual anymore to live to be 80, and that's why a new report in JAMA, the Journal of the American Medical Association, says those folks need to know that as good as they may feel. There's a very good chance they have high blood pressure.
"What we found is that among the oldest individuals, those 80 years of age and older, more than 75% have high blood pressure," says Donald Lloyd-Jones M.D. Northwestern University. That's after tracking more than 5,000 seniors for up to six years. The real concern is the study also showed that only about a third of those seniors who could benefit from high blood pressure medication were taking it.
The researchers say that physicians should be more aggressive in treating high blood pressure in the elderly, and that older people should be more aggressive in seeking treatment for their high blood pressure. For more information, visit ( jama.com).
Many use fortified drinks to help battle low calcium levels, but new studies say you might not be getting all the calcium you think. Researchers at Creighton University in Nebraska examined the amount of calcium that women actually absorbed from calcium fortified drinks, like orange juice. In the tests, some of the beverages had a layer of calcium on the bottom of the bottle that was difficult to re-mix even with vigorous shaking. Other drinks contain calcium that was more difficult to absorb.
