Medical Notes this week…
Antibacterial soaps are common today, as are antibacterial toothpaste, mouthwash, cosmetics, and even clothing and baby toys. But a new study finds that the active ingredient in most of those things could actually be making bacteria more able to withstand medications. The study in the journal Antimicrobial Agents and Chemotherapy shows that the chemical triclosan (trick-lo-san) does kill some microbes, but those that are left are substantially more resistant to antibiotics.
Men who have enlarged prostates may worry about prostate cancer, too. But a new study suggests that enlarged prostates actually protect against prostate cancer. The key is that the prostate sits in a confined space. Scientists believe that as the prostate becomes enlarged, it’s squeezed tightly, impeding the growth of cancer cells inside. The study appears in the Proceedings of the National Academy of Sciences.
And finally… over the last decade, many laws have locked up most of your sensitive medical data. But a new study shows that “shadow” health records generated just by living your life can tip off a lot about your health, and those records are wide open. The study in the journal Science Translational Medicine finds that using a fitness tracker, smartphone health app, or DNA ancestry test leave a health information trail. Shopping for a health-related item online or even searching the internet for health information leaves clues for savvy data gatherers.
