Report: 3D mammograms are better for cancer screenings. A study published in the Journal of the American Medical Association says that 3D mammogram scans do a better job of detecting more invasive cancers earlier than the standard mammogram. In a standard mammogram, only one image of each breast is taken from two positions, while several images of layers of each breast are scanned with a 3D scan. However, there are drawbacks to the 3D scan, including higher cost, more radiation and less insurance coverage. See the study at tinyurl.com/lsqn5ya.
Scientist faces prison for fraudulent AIDS research. A researcher in Iowa faces prison time after investigators learned he had falsified data to get millions in grants from the National Institutes of Health. Dong-Pyou Han allegedly spiked rabbit blood with human antibodies to make the HIV vaccine he was working on appear to have great promise, according to The Associated Press. The 57-year-old was indicted on four counts of making false statements and he could face up to five years in prison for each count. Experts said it is a rarity to bring about criminal charges in research fraud cases.
Panel: No recommendation for routine vitamin D screening. The U.S. Preventive Services Task Force, an independent panel of health experts, said there was no sufficient evidence to recommend routine vitamin D screening. They said physicians should look at it case by case. Researchers have connected low levels of vitamin D to cancer, heart disease and other chronic illnesses. However, the panel believes there may be flaws in the way it is being tested, leading to misleading results. The panel said it’s unclear if healthy adults with low vitamin D levels would benefit from taking supplements.
