The usual magazine summaries
Nov. 17th, 2006 06:48 pmI've got a stack of magazine articles dog-eared to share, time to clear them off the desk!
First, in New Scientist from 20 October, an article entitled "Alzheimer's alert over anesthetics." (Well, it actually uses the British spelling, anaesthetics.) Last month at the annual meeting of the Society for Neuroscience, in Atlanta,a medical researcher said that the inhaled anesthetics halothane and isoflurane encourage clumping of beta amyloid protein, as does the common IV anesthetic propofol. This protein clumping is similar to that seen in Alzheimer's cases, and may account for the memory and attention problems many patients have after surgery. ("There are plenty of anecdotal reports about elderly relatives never being quite the same after going in for surgery.")
Why this is important to us: the inhaled anesthetics are not commonly used on people in the US or Europe, more in Asia and Africa, but isoflurane *is* commonly used in the US for pets - in fact, it's about the most common anesthetic in use for small and exotic pets, because it has so few of the side effects of more traditional anesthetics such as nausea and lack of appetite. Anyone who has had their rabbit neutered, or their guinea pig's rear molars treated, the pet probably had isoflurane as the anesthetic. So, since these studies were on animals, we can assume that the brain protein clumping definitely applies to them. The upshot seems to be that exposure to isoflurane (and the others) is more likely to cause the problem if you are exposed repeatedly, and/or if you are elderly. Which means, I think, that if you are deciding whether to put an elderly pet through surgery for something, and considering the benefits vs. the risks, this is another factor to take into account.
I could swear I already mentioned the article in the September 30 issue of Science News, about penguins that nest in cactus. Why is it still on my desk?
Let's see, an article from Woman's Day about heart failure - that belongs on my other blog.
And from Science News, August 12, "Scientists find midnight-snack center in brain." The article is more technical, and is about studies on mice, but isn't that a great headline?
Non-science related: the October issue of In These Times recommends a book called Cable News Confidential: My Misadventures in Corporate Media, by Jeff Cohen. Says it's a fun read, not as dry as most media criticism.
That leaves another 3 magazines with no pages tabbed down, still sitting on my desk. Why did I put them here?
