(June 22, 2009 - Insidermedicine) From Florida - According to research in The Lancet Infectious Diseases, MRSA may be carried by the family pet. Researchers have found that cats and dogs can be colonized by methicillin-resistant Staphylococcus aureus, which can cycle back and forth between pet and owner. While petting and handling pets will not result in infection very easily, in the U.S., dog and cat bites make up about 1% of ER visits every year.

From Boston - According to research in the British Journal of Ophthalmology, the link between omega-3 fatty acids and lower risk of age-related macular degeneration may be modified by other dietary supplements. In a study of over 2,900 patients, researchers found that in those with early AMD progression, the protective effect of omega-3s was eliminated in those taking high doses of antioxidants or zinc.

And finally, from Washington - According to research presented to the Endocrine Society, a new combination therapy may boost weight loss. In a study of 800 overweight adults, researchers found that those who received a fixed-dose combination of naltrexone and bupropion lost nearly 10% of their baseline body weight in a year. This was 82% more than behavioral therapy alone.
