Medical Notes this week…

Chemicals called PFC’s are used to make non-stick pans, stain-resistant carpets and water-repellent jackets. They’re already linked to a variety of diseases. Now a new study finds that PFC’s may also make it much easier for people to regain weight after a diet. The study in the journal PLOS Medicine followed more than 600 people during and after being on a diet. The average subject gained back about half what they’d lost but those with the highest blood PFC levels regained an average of five pounds more. Researchers say resting metabolism rates were much slower in those with high PFC levels leading to easier weight gain.

We’ve reported on bullying and incivility in America’s offices recently and we noted that women report more incivility against them than men. But the source of most of that incivility may surprise you—other women. A study in the Journal of Applied Psychology shows that the queen bee syndrome is alive. Women reported that other women were more likely than men to put them down, make demeaning remarks or ignore them in a meeting.

And finally, when it comes to living past age 90, which is more important to partake in—exercise or alcohol? The answer–drink up. A study presented to the American Association for the Advancement of Science shows that 15 to 45 minutes of exercise per days cuts your risk of premature death by 11 percent. But two glasses of beer or wine per day cuts that risk by 18 percent.

And that’s Medical Notes this week.
