...storm of competition, America in particular must return to basics. The most critical building block is education. Despite years of hand-wringing and higher spending than that of other industrialized nations, U.S. schools threaten to leave the nation less competitive in global labor markets. A barrage of test scores shows American students are already far behind the world's academic leaders. U.S. universities are still considered the best in the world. But compared with their international peers, American eighth graders in 2003 ranked 14th in math-just beating out Lithuania's kids-and ninth in the world in science...
...Last week, in Delhi, I set out to test attitudes to a young, single woman seeking accommodation. In the main market of the middle class neighborhood of Dwarka, half a dozen property agents line a busy street, eager to cash in on the property boom that has gripped the capital. The first agent I tried seemed hesitant to speak to me, and explained that it would be "difficult" to rent a house to a single woman. He listed a series of apartment complexes that maintained unofficial policies allowing them to lease "only to families." Owners don't like the parties...
...calcified or non-calcified plaque," says Dr. Norman Lepor, a professor at UCLA's Geffen School of Medicine, referring to the tell-tale build-up on artery walls that signifies heart disease. Lepor says that CTCA gives off no more radiation than the routinely used diagnostic nuclear stress test, which also detects plaque deposits, but only those that are big enough to block 70% of the artery. "The risk-benefit assessment is in favor of cardiac CT to be used in a judicious fashion," says Lepor, who describes good candidates for the scan as male, over age 40 with...
...Einstein expects that the new study's findings will have several implications in the everyday practice of medicine. "I think this can reassure a lot of patients that CTCA is a good test-and a safe test particularly for older patients," says Einstein. "On the other hand, for younger women, I think it may affect physicians' thinking in terms of the risk-benefit ratio of the test...
...Because of the potential hazards involved with radiation exposure, Einstein warns patients against attempts to "get pretty pictures of their heart" without a doctor's recommendation. Otherwise, he says, the CTCA can be an excellent noninvasive alternative to the current gold standard test for heart disease, the coronary angiography, which involves threading a catheter from the groin to the heart's blood vessels, and can cause complications such as blood clots, infection and even death. CTCA is also a good substitute for the time-consuming diagnostic tests in use in emergency departments; with CTCA physicians can find out sooner when...
