Group Wants to Nix These Tests

1 Five Medical Tests You May Not Need

An MRI or CT scan after fainting is one of five tests that doctor groups say that patients often don't need. According to a report released today by the American Board of Internal Medicine Foundation, the Consumers Union and nine physician groups, some standard medical tests that patients have come to expect are often overused. Besides the scans after fainting, the groups also say that patients often don't need an annual cardiac stress test if patients are otherwise healthy since the tests rarely change treatment. Other overused tests noted include repeat colorectal cancer screenings, a chest x-ray before outpatient surgery, and a back scan within first six weeks of lower back pain.

LFTB to Be Listed

2 Companies to Tell You About Their Pink Slime

Consumers have been very surprised to learn that ammonia-treated beef filler is included in much of the ground beef for sale, and now some producers are asking if they can voluntarily list the controversial lean finely textured beef (LFTB) filler on their labels. LFTB has been renamed "pink slime" by critics. MSNBC reports that the USDA will approve requests from unidentified companies who've asked for labeling changes. Cargill Inc. has said that they requested the labeling change to help address consumer concerns, but no final decision has been made. The beef company says they're working with customers to reach "mutually acceptable options."

Get Out of the Fat Store

3 Discount Supermarkets Linked with Weight

Shopping at a discount supermarket may affect your weight, suggests a study conducted in Paris, France. Participants who shopped at discount supermarkets, or in supermarkets far from home, had higher body mass indices and waste circumferences. Researchers say the association was stronger for those participants with less education. However, the supermarket size and produce quality didn't correlate with BMI or waist circumference, say researchers. The study, led by French researcher Basile Chaix, was published in PLoS ONE.

Genetics of Autism Complex

4 Autism Tied to Mutated Genes from Dad

After recent reports of one in 88 American children affected by autism spectrum disorders, three studies which involved sequencing large areas of DNA that code for proteins suggest that mutated genes from dad contributes to the condition that ranges in severity. One study shows a direct link between the age of the father and the likelihood of autism and another comparing siblings without autism to siblings with the disorder found that there were two genetic variations in the SCN2A gene. The third study suggests that genetic mutations found in autistic children but not the parents are unrelated to autism. Researchers conclude that the genetics of autism are complex and stress that having these mutations may increase the risk but does not mean a child will develop autism.
