ROCHESTER - Calls made on cell phones do not affect hospital medical devices, U.S. researchers published in the March issue of Mayo Clinic Proceedings.
Tests at the Mayo Clinic in Rochester, Minnesota showed normal use of cell phones, also called mobile phones, caused no noticeable interference with patient care equipment, they said.
Most hospitals forbid the use of cell phones.
TORONTO - Patients who have a stroke are less likely to die within the next week if they are admitted to a hospital on a weekday rather than over the weekend, neurologists in Canada report.
NEW YORK - X-ray screening for lung cancer may not save many lives, a team of U.S. and Italian researchers reported in a study that adds to a growing debate.

HONOLULU - Oral contraceptives with low levels of estrogen and progestin reduce the risk of ovarian cancer even more than older versions of the "Pill", according to investigators at the University of Hawaii in Honolulu.
STANFORD - A study of four popular diets found that women put on the one with the least carbohydrates -- the Atkins plan -- lost at least twice as much weight as those on the others, researchers reported in a new study.
"Many health professionals, including us, have either dismissed the value of very-low-carbohydrate diets for weight loss or been very skeptical of them," said Christopher Gardner, assistant professor of medicine at the Stanford Prevention Research Center in California, lead author of the study.
