Forget football. At many high schools, the fiercest competition is between Coke and Pepsi over exclusive "pouring rights" to sell on campus. But last week Jeffrey Dunn, president of Coca-Cola Americas, called a timeout: Coke’s machines will now also stock water, juice, and other healthful options--even rival brands and their facades will feature school scenes and other "noncommercial graphics" instead of Coke’s vivid red logo. "the pendulum needs to swing back" on school-based marketing, said Dunn. Coke’s about-face--particularly the call to end the exclusive deals that bottlers make with school districts--comes amid rising concern over kids’ health: American children are growing ever more obese and developing weight-related diseases usually found in adults. While inactivity and huge helpings factor heavily, a recent study in the Lancet fingered soda pop as a likely culprit. Communities--and legislators--are already on the case. Last year, for instance, parents in Philadelphia detailed a proposed contract with Coca-Cola that would have netted the school system $ 43 million over 10 years. And in a searing’ report to congress last month, the U. S. Department of Agriculture recommended that all snacks sold in schools meet federal nutrition standards (the requirements are loose enough that Snickers bars qualify). Spare change Activists hope Coke’s capitulation will help curb commercialism in schools altogether. From ads on Channel One, which broadcasts current-affairs programs on classroom TV, to middle-school math texts that cite Nike and other bran-name products in their word problems, to company-sponsored scoreboards on football fields, American pupils are bombarded. But Andrew Hagelshaw, executive director of the Oakland, Calif.-based Center for Commercial-Free Public Education, views Coca-Cola’s policy shift as a "partial victory". Schools sign contracts with local bottlers; the parent company can only urge them to back off. Moreover, Coke’s machines will remain in place, although with healthier options. And don’t expect teenagers to suddenly swear off the stuff--or school districts to give up the revenue. At Wheeler High School in Marietta, Ga., where students arrive before 7 a.m. and stay as late as 11 o’clock at night, they rely on the machines. And the $ 50,000 in annual vending revenues have enabled Principal Joe Boland to refinish the gym floor, in- stall a new high-jump pit, and pay $ 7,000 for two buses. "If someone made an offer to me to take the machines out, I’d consider it," says Boland. "But nobody’s offering me any money.\ The phrase "back off" in boldface in this context probably means ______.

Most people who develop Lyme disease, a tick-born infection that’s endemic in parts of the Northeast and Midwest, are easily cured by taking an antibiotic like doxycycline for a couple of weeks. But for years a debate has raged over what to do about patients whose symptoms (fatigue, mental confusion, joint pain) never seem to clear up. One small but vocal group of doctors and patient advocates believes that Lyme’s corkscrew-shaped spirochetes have tunneled deep into their victims’ bodies and can be eradicated only with intensive antibiotic treatment over many months. Another group believes, just as adamantly, that the bacteria are long gone, making further treatment with powerful antibiotics-- which can lead to potentially fatal infections or blood clots--positively dangerous. Now comes word of two studies in the New England Journal of Medicine that show that long-term antibiotic treatment is no better than a placebo for folks with chronic Lyme disease. Originally scheduled for publication in July, the research is part of a group of findings made public last week--just in time for the peak Lyme months of June and July. If confirmed by another major study that’s looking at chronic Lyme and antibiotics from a slightly different perspective, the results would seem to settle the question once and for all. Researchers from Boston, New Haven, Conn., and Valhalla, N.Y., followed 129 patients who had previously been treated for well-documented cases of Lyme disease. Sixty-four were given antibiotics directly into their veins for a month, followed by two months of oral antibiotics. The others received dummy medications. A third of the chronic Lyme patients got better while taking the antibiotics. But so did a third of those on the placebo. Indeed, the results were so similar that a monitoring board decided to cut the trials short rather than add more subjects to the test groups. Unfortunately, the debate over chronic Lyme has become so heated that no one expects the controversy to go away. But both sides may take comfort in the other findings that were released by the New England Journal last week. After studying 482 subjects bitten by deer ticks in a part of New York with a lot of Lyme disease, researchers concluded that a singly 200-mg dose of doxycycline dramatically cut the risk of contracting the disease. That good news is tempered somewhat by the fact that 80% of patients who develop the infection don’t remember ever being bitten by a tick. (The bugs inject an anesthetic into the skin to mask the pain and in their nymph stage are so small--about the size of a poppy seed--that they are easily overlooked. ) There’s still plenty you can do to protect yourself in a Lyme-infested neighborhood: tuck your pants in your socks, spray DEET on your clothing, check yourself and your kids for ticks. And if you develop a spreading red rash--particularly if it’s accompanied by joint pain, chills or confusion--make sure you see a doctor right away. The trick, as always, is to be vigilant without overreacting. What useful information can be drawn from the passage by a chronic Lyme patient
