July 4, 2012 - The American Red Cross desperately needs more people to roll up their sleeves and donate blood. In June, the agency reported its supply had reached emergency levels. The Red Cross says all blood types are welcome, but there's a particular need for O positive, O negative, B negative and A negative to meet expected patient demand this summer. Type O negative is the universal blood type and can be transfused to anyone who needs blood. Everyday, the Red Cross must collect more than 17-thousand pints of blood for patients in need across the country.
Also, health regulators are taking a closer look at metal hip replacements. Doctors have used the implants on half a million Americans. In about 6 percent of patients, the implants had to be replaced in less than five years, even though they're supposed to last for at least ten. Unlike other countries, the US has no national registry to track the performance of implants over time.The food and drug administration is investigating the problem after years of patient reports of pain and swelling that sometimes requires removal of the devices.
