Exercise, Healthy Diet Urged after Cancer

Exercise and healthier eating may help to keep cancer from returning after treatment, the American Cancer Society says. The new advice was based on dozens of studies published in the last five years. The studies found lower rates of cancer return (recurrence) and longer survival for people with better diet or exercise habits. The studies were mostly observational. The cancer survivors were not randomly assigned to one program or another. So the studies can’t prove that exercise or diet caused the better outcomes for these patients. But the cancer society said the number of studies made their results worth trusting. Most involved prostate, breast or colon cancer survivors. The new guidelines urge doctors to talk to cancer patients about moving more, eating healthier foods and losing weight, if needed.

Less Radiation to Find Appendicitis

Doctors may be able to diagnose appendicitis with a scan that uses a much lower dose of radiation, a new study finds. The study included 891 people. All of them were between ages 15 and 44. All had suspected appendicitis. Researchers randomly assigned half of them to receive a low-dose computed tomography (CT) scan of the abdomen. The others had a standard-dose CT scan. In all, 172 people in the first group were diagnosed with appendicitis. In the standard-dose group, the number was 186. During surgery, doctors discovered that just over 3% of each group did not have appendicitis. So the low-dose scan was just as accurate as the standard scan, researchers said. The standard scan used about 8 millisieverts of radiation. The low-dose scan used 2 millisieverts, or one-quarter as much. The New England Journal of Medicine published the study. HealthDay News wrote about it April 25.

Only 13% in U.S. Have High Cholesterol

Though Americans have high levels of obesity, only 13% have high total cholesterol. That’s the finding of a report from the U.S. Centers for Disease Control and Prevention (CDC). The numbers come from a survey of 6,000 adults in 2009 and 2010. They also had blood tests taken. The group was chosen to represent the variety of U.S. adults. The 13% with high total cholesterol is less than the U.S. government goal of 17%. Women met that goal about 5 years ago and men about 10 years ago. The CDC did not find out why cholesterol has dropped. But officials said they believed it was related to less smoking and more people taking drugs to lower cholesterol. The CDC released the report April 25. The Associated Press wrote about it.

A Guide to Migraine-Prevention Drugs

Most people who can be helped by medicines to prevent migraines don’t take them, a new report says. The report offers guidelines for treatment. About 40% of people with migraines can be helped by preventive medicines, one author of the guidelines told HealthDay News. They can reduce the number of migraines by half. They can also help make the migraines shorter and less severe. But only about one-third of those who can benefit are taking the medicines, the author said. The guidelines were based on 29 studies of drug treatment for migraines. All of them compared the medicines with placebo (fake) pills. Two main groups of drugs were found to help. They are anti-seizure medicines and beta-blockers (also used for high blood pressure). Frovatriptan (Frova) can help prevent migraines around the time of the menstrual period.

Doubts about Use of Medicines in Autism

A type of antidepressant sometimes used to treat autism may not help much at all, a new analysis of research finds. The study focused on drugs called serotonin receptor inhibitors (SRIs). These include drugs such as fluoxetine, citalopram and others. Some research has suggested they could help control repeated behaviors in people with autism. The new study put together the numbers from earlier studies. It included results from five published studies. These studies found a small benefit for people who took SRIs, compared with placebo (fake) pills. The new study also looked at five prior studies that were never published. When those results were combined with the published studies, the benefit from SRIs disappeared. They appeared to help only people with anxiety as well as autism. The authors say “publication bias” may account for their findings.
