THE SALINA JOURNAL HEALTH & SCIENCE FRIDAY, APRIL 6, 2001 A7 T HIGH HEEL STUDY New study not high on heels . High heels, whether vthin or wide, can lead to knee arthritis ; By ERIN SULLIVAN The Associated Press " LONDON — Healthy knees aren't the main consideration V in choosing among high heels, but new research says chunky : heels are just as bad for the ; knees as spindly stilettos. Some women who want to " add a bit of height and walk comfortably opt for wide heels. But comfort is the problem: Because they can be suffered for longer, such shoes are just as likely to cause knee arthritis, " scientists report in The Lancet I- medical journal this week. "It takes a long time to feel •the effects of knee osteoarthri­ tis — and once you do, it's too late," said Dr. Casey Kerrigan, lead researcher of the study and associate professor at Harvard Medical School's department of physical medicine and rehabilitation. "I liken it to smoking — one cigarette is not painful, but over a lifetime it is. Wide- heeled shoes feel comfortable, so women wear them all day long," Kerrigan said. "They are better for your feet than stiletto heels, but just as bad for your knees." In the study, researchers had 20 women wear two pairs of shoes with three-inch heels, one with a narrow heel and the other with a thick one. The scientists compared how much pressure was put on the women's knees by both types of shoes. The women also walked barefoot to provide a reading of normal pressure. The scientists found that both types of shoe applied equal amounts of pressure to the knees. Compared with walking barefoot, the heels increased pressure on the inside of the knee by 26 percent. Increased pressure on the knee eventually leads to arthritis, experts say. The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns and calluses to hammer toes, tendinitis, knee pain, sprained ankles and back problems. But, in 1998, Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful, degenerative joint disease that destroys cartilage surroxmding the knee. The first study looked only at stiletto heels, and Kerrigan said she wanted to investigate the chunky high-heeled shoes she noticed many women wearing. "This article confirms what we all intuitively know — that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeffer, a San Francisco orthopedic surgeon and member of the American Academy of Orthopedic Surgeons, who was not connected to the study "Clearly this is a red flag saying, 'Don't fool yourself into thinking th&t because you are wearing a wider heel that you won't have problems,' " Pfeffer said. EATING DISORDERS Genetic mutation linked to anorexia By MATT CRENSON The Associated Press Researchers have found that one form of a gene involved in controlling appetite is more frequent among anorexics, a discovery that suggests disruptions of the brain's system for governing food intake contribute to eating disorders. This is the first time an anorexia-related gene has been identified, though researchers have known for several years that a person's chances of developing an eating disorder depend partly on genetics. The study by researchers from Germany and the Netherlands found 11 percent of anorexics had a variant form of the gene for agouti-related protein, a chemical mes­ senger that stimulates appetite. In contrast, only 4.5 percent of subjects without anorexia had the variant form. The study compared 145 anorexia patients and 244 people without the disorder and concluded that having the mutation more than doubles a person's chance of developing anorexia. The finding suggests a drug mimicking agouti-related protein might help some anorexics regain their appetites. The study was published in the May issue of Molecular Psychiatry It is certainly not the only gene involved in the disease. Researchers believe many genes work together with environmental factors to cause eating disorders. • STAR SEARCH $56 million awarded in ien-phen' case ALICE, Texas — A jury has awarded more than $56 million to a woman who took the weight loss drug fenfluramine, ending the first of dozens of local pending "fen-phen" cases. Gloria Lopez, 48, said she developed heart valve damage after taking the drug for about six months in 1997, shortly before the Food and Drug Administration called on American Home Products to withdraw Fondimin, the drug's brand name. Fenfluramine, along with phentermine, make up the fen- phen combination, which was used by an estimated 6 million people nationwide in their quest for weight loss. The jury ordered American Home Products to pay Lopez, an employee of the Alice Independent School District, $45 million in punitive damages and $11.5 million in actual damages Tuesday Calorie restriction may extend life Researchers are finding the first evidence of hormonal- based aging mechanisms that may promote long life in species ranging from fruit flies and roundworms to humans. Three studies reported today in the journal Science indicate the insulin-signaling pathway acts to regulate aging in a number of organisms. And because insulin signaling is influenced by how much an animal eats, the scientists also suggest restricting calories might extend life span in humans and other animals, just as it's already been shown to do in rodents. "We think that in flies and worms and probably in humans, insulin-like compounds mediate aging by either retarding growth or by activating specific endocrine tissue to release other hormones," said Marc Tatar, lead investigator of a research team at Brown University Research to improve replacement hips ; Painful and complicated as they are, artificial replacement hips may not last as long as a patient needs them. • Swiss researchers reported Wednesday that they're developing new plastic materials that are more compatible with the body's natural joint-lubricating proteins and could make hip replacements last much longer. Every year, more than 300,000 people undergo hip-re- pjlacement surgery The artificial joints usually last between 10 and 15 years. That was fine a generation ago, when few people getting hip replacements in their 60s and older lived another decade. But now, with elderly people living longer, there's a need for better, longer-lasting artificial parts, and materials scientists and medical-device manufacturers are trying to meet the new demands. From Wire Service Reports Gamma-ray sheds light Gamma-ray burst leads to discovery of 'a stellar nursery' By ANDREW BRIDGES Tlie Associated Press LOS ANGELES — A powerful gamma-ray burst led a team of astronomers to the discovery of a stellar nursery that is producing one to two new stars a day some 8 bUlion light-years from Earth. The discovery announced Wednesday appears to support the theory that gamma-ray bursts occur when young, massive stars explode and hints at a novel way of pinpointing galaxies in the distant universe that may harbor star-forming regions. Gamma-ray bursts, first detected three decades ago, are the most powerful explosions known. In a matter of seconds, a gamma-ray burst can release more energy than the sun. Another theory of their origin says the bursts occur when neutron stars collide. The gamma-ray burst detected in late February acted like a beacon to draw the interest of astronomers to the constellation Bootes and an unnamed star- burst galaxy which is difficult to study because of its distance. Follow-up observations, including measurements made at the shortest wavelength of radio emissions capable of piercing the Earth's atmosphere, re- • GENETIC CODING YEN CHING Chinese Restsaurant DELIVERY 823-1685 Dine In & Carryout 540 S.

Astronomers had expected the signal to brighten as a shock generated by the burst moved through a cloud of dense gas.
