Input: Consider Input: Paragraph: The study tracked about 20,000 severely obese patients with Type 2 diabetes. Those who had weight loss surgery had a 40 percent lower chance of developing a heart attack or stroke in the five years following surgery compared to those who got usual care with diabetes medicines or insulin. For every 1,000 patients in the study who had surgery there were roughly 20 heart attacks or strokes compared to 40 such events per 1,000 who got regular care. More than 30 million Americans have diabetes, mostly Type 2 where the body loses the ability to produce or use insulin to turn food into energy. Other research has shown obesity surgery can reverse and even prevent diabetes. Taken together, it means doctors should discuss weight loss surgery more often, said study co-author Dr. David Arterburn of Kaiser Permanente Washington Health Research Institute in Seattle. Doctors usually mention insulin and pills, “but it’s not always brought up that weight loss surgery is another available treatment option,” Arterburn said. Researchers analyzed records from four U.S. health care systems: HealthPartners in Minnesota and Kaiser Permanente in Washington state, Northern California and Southern California. Results were published Tuesday in the Journal of the American Medical Association. The study can’t prove cause and effect because patients weren’t randomly assigned to get surgery. The researchers tried to match patients for gender, age, blood sugar levels and other factors. But other things they didn’t account for could have contributed to the surgery patients’ better results. Everyone in the study had a BMI, or body mass index, of at least 35. For instance, someone who is 5-foot-8-inches and weighs 230 pounds has a BMI of 35. Of the more than 5,300 who had surgery, most had gastric bypass, the most common type of stomach-shrinking operation. Some had gastric sleeve or gastric band procedures. The rest, nearly 15,000 people, had usual care. Obesity surgery can cost $20,000 to $25,000. Insurers are increasingly covering it, but some impose strict limits. The new findings suggest insurance coverage should be expanded for the right patients, Dr. Sayeed Ikramuddin of the University of Minnesota wrote in an accompanying editorial. Surgery is thought to help by affecting hormones, gut bacteria and other substances that affect how the body handles insulin and blood sugar. Weight loss without surgery also helps, but is difficult for many people to achieve. Most weight loss surgery today is done through small incisions. The dangers are similar to other surgeries, including a small chance of life-threatening complications, and some people need to have their surgeries repeated. ___ Follow AP Medical Writer Carla K.

Output: Obesity surgery may dramatically lower the danger of heart attacks and strokes in patients with diabetes, new research suggests, reinforcing evidence that benefits extend beyond weight loss.


Input: Consider Input: Paragraph: Three of the other five patients are in either a serious or a critical condition in hospital, while the remaining two have mild symptoms, the United Nations health agency said in a disease outbreak update. H7N9 bird flu emerged last year in China and has infected around 150 people so far there and in Taiwan and Hong Kong, killing at least 46 of them. The latest death was a 38-year-old man from China’s Fujian Province who became ill with H7N9 on January 3, was admitted to hospital on January 8 but died 2 days later. He had underlying illnesses, including tuberculosis and pneumoconiosis. China’s state news agency Xinhua reported another death from H7N9 in the southwestern Guizhou province on Monday, but this has yet to be confirmed by the WHO. A 65-year-old man infected with H7N9 also died in Hong Kong, the government said on Monday. The WHO reiterated there is no evidence as yet of any easy or sustained person-to-person transmission of the strain, and that the source of the human infections is still under investigation. Researchers in the United States said last month that while it is not impossible that H7N9 could become easily transmissible between people, it would need to undergo multiple mutations to do that. Scientists around the world are keeping a watchful eye, on alert for any sign the virus might develop that potential and start to spread rapidly. Claim: Death toll from new China bird flu rises: WHO.

Output: Six more people in China have been confirmed as infected with the new H7N9 strain of bird flu and one of them has died, the World Health Organisation (WHO) said on Monday.


Input: Consider Input: Paragraph: A staple in senior citizen centers and a common dawn sighting in public parks, the practice can offer long-term benefits for all age groups. “In this high-tech world that’s all about speed, greed and instant gratification, tai chi is the antidote to bring us back to balanced health,” according to Arthur Rosenfeld, a tai chi master and the author of a new book called “Tai Chi — The Perfect Exercise: Finding Health, Happiness, Balance, and Strength.”  “It doesn’t mean you can win the marathon or clean and jerk 750 pounds or win a cycle sprint,” said the South Florida resident, 56. “It’s not about getting there sooner.” Tai chi is more about how the body works than how it looks, and is about aging gracefully and “with less drama.”  “The last time I looked, there were some 500 studies about the various physical benefits of tai chi, from improving balance and attention span to boosting the immune system to beating back the symptoms of arthritis, asthma and insomnia,” said Rosenfeld. An estimated 2.3 million U.S. adults have done tai chi in the past 12 months, according to a 2007 National Health Interview Survey. The practice is not perfect. Tai chi “does not supply the cardiovascular component that we’d be looking for in a well-rounded routine,” said Jessica Matthews, a San Diego, California-based exercise physiologist. “The exertion level, while challenging, is not going to increase your heart rate.”  T’ai chi ch’uan, as it is formally known, derives from a form of Chinese martial arts. Explaining the slow, circular movement of the practice, Rosenfeld said tai chi is a philosophical term that means the harmonious interplay of opposing forces. When nature encounters a strong force, the way it answers that force to maintain harmony in the world is with a spiral, he said. “Astronomers see galaxies moving in spirals, water goes down the drain in a spiral, tornados form as a spiral. We spiral in tai chi because the most effective way to move fluid through solid is a spiral.”  Hawaii-based personal and group-fitness trainer Jordan Forth, who has studied tai chi since 2006, said one translation of tai chi is “grand ultimate motion.”  “I recommend it to everybody,” said Forth. “It teaches people to move well in multiple planes of motion with a state of awareness not cultivated in everyday fitness. Most people check out on a treadmill or during high-intensity activity.”  Forth said tai chi improves mobility, movement and flexibility and can be even more dynamic than yoga, which the 35-year-old has studied since he was a teenager. “With tai chi you’re grounded the entire time,” he said. “For me, (it) translates more into functional everyday movement.”  Matthews, who is also a spokeswoman for the American Council on Exercise, said because tai chi is slow motion and low impact, many assume it’s just for older people or not a viable means of exercise. Not so, she said: Research studies have found that the practice increased mineral bone density, boosted endurance, strengthened the lower body, and eased depression. Claim: Tai chi: getting there more slowly, but gracefully and intact.


Output: For modern, harried lifestyles focused on getting and spending, fitness experts say tai chi, the ancient Chinese slow-moving exercise, can be an ideal way for anyone to stay fit.
