U.S. cases of diabetes will nearly double in the next 25 years, a study predicts. Spending to treat people with the disease will triple, researchers estimated. They previous estimates have been too low. About 23.7 million people in the United States today have diabetes. The study predicts there will be 44.1 million by 2034. By then, spending will hit $336 billion a year, researchers said. About half of this total will be paid by Medicare, they said. The study appeared in the journal Diabetes Care. HealthDay News wrote about it November 27.

Several doctor groups and advocacy groups publish their own guidelines for cancer screening. The U.S. Preventive Services Task Force also issues guidelines. Last week, the task force changed its advice about breast cancer screening. Right away, some experts and groups disagreed. But experts don’t always agree on screening for other types of cancer either, the Associated Press reported November 20. Group guidelines may differ on who should be tested and how often. The AP story summarized guidelines for breast, cervical, prostate and colon cancer.

A California surgeon is on trial this week, charged with speeding up a man’s death in order to take his organs for transplant. Ruben Navarro had severe disabilities. He was 25 years old when he died in 2006. First, he had a heart attack. Then he was in a coma for a while before death at Sierra Vista Regional Medical Center in San Luis Opisbo. Hootan Roozrokh, M.D., a transplant surgeon, was involved with the case. He is charged with one count of felony adult dependent abuse. Two other charges were dismissed. The Associated Press wrote about the case November 2.

Having four bad health habits can age you by 12 years, a new study concludes. The study included nearly 5,000 British adults. First, researchers asked them about smoking, alcohol use, exercise and diet. In all, 314 people had bad habits in all 4 of these areas. They smoked. They had more than 3 alcoholic drinks a day (2 for women). They exercised less than 2 hours a week. And they ate fewer than 3 fruits and vegetables each day. About 29% of this group died in the next 20 years. Another group, 387 people, had none of these bad habits. Only 8% of them died during the study. The difference in death rate is equal to about 12 years of aging for the people with the bad habits, researchers said. The study appeared in the journal Archives of Internal Medicine. The Associated Press wrote about it April 27.

Researchers have found the first genes linked to stuttering, and they say this could lead to a treatment someday. Stuttering is known to run in families, so a genetic link had long been suspected. To learn more, researchers looked at a large Pakistani family. Many members of the family stuttered. Researchers found a mutated gene on chromosome 12. Then they looked at the genes of 400 other stutterers from Pakistan, the United States and England. Researchers found the same mutated gene and two others. They also looked at the genes of people who did not stutter. Only one person had the mutations. Researchers said two of the genes also have been linked to rare disorders of cell metabolism. These conditions are being treated by replacing a missing enzyme. Something similar might help stuttering. The study appeared in the New England Journal of Medicine.

Most people in the hospital for heart failure don’t get sent home with a drug that could prevent a return visit, a study finds. The drug is spironolactone, a water pill. This drug helps to prevent fluid buildup in the lungs, blood and elsewhere in people with heart failure. It has been shown to reduce hospital stays and deaths. But it also can be dangerous in some people, such as those with kidney problems. The study included 201 hospitals. More than 12,500 patients were eligible to receive spironolactone. But only about one-third received the pills. Guidelines for doctors have recommended this drug for heart failure since 2005. The study appeared in the Journal of the American Medical Association. The Associated Press wrote about it October 21.

People have been urged to eat more fish for the sake of their health. But doctors writing in a medical journal say it’s not possible for everyone to follow this advice. The world’s fish stocks are not big enough. Poor countries already are losing their supplies of fish as people in richer countries eat more of it. The authors also say there’s not enough evidence that eating fish improves health. Not all studies have found a benefit from fish. The article appeared March 17 in the Canadian Medical Association Journal.

New studies show high quality of life for breast cancer survivors and hopes for new treatments. One study surveyed 1,050 women who were treated for early-stage breast cancer. The follow-up lasted up to 15 years after treatment. The women said their quality of life was very high and their health average. Less than 5% reported severe problems with pain, usual activities or self-care. In another study, three weeks of radiation treatment worked as well as five weeks. A third study compared acupuncture with an antidepressant to relieve side effects of treatment. They were equally effective. Acupuncture caused fewer side effects. HealthDay News reported on the studies. They were presented September 21 and 22 at a conference.

More middle-aged people are making a major effort to “manage” aging, the Associated Press reported December 8. They do more than just exercise and eat healthy foods. Other tactics include hormone injections, severe calorie cutting and Botox. A few extreme treatments have raised safety concerns. They include radon gas, fetal cell injections and removal of testicles. Even young people seem to be affected. A survey found that one-third of teen girls wanted plastic surgery to improve how they looked. Age “managers” say they want long, healthy lives. Some say looking young also helps their careers.

New techniques may make ovary transplants useful for more women, researchers say. Now some women have ovaries removed before treatment for cancer or other serious diseases. This prevents damage to eggs from treatment. The ovaries are frozen and transplanted later. But few procedures have succeeded. Now researchers have announced new techniques at a conference. One group froze ovaries faster and saved nearly all of the eggs. Slow freezing saved only half of them. Another group tried implanting just part of the ovary first. This helped the body to get blood and hormones flowing before the transplant. Researchers said these techniques may help healthy women, too. They may be able to freeze ovaries when they are young. They would get a transplant later, when they wanted to have a baby. The Associated Press wrote about the research June 29.
