I don’t plan to sell my organs on eBay, but as organ transplantation, lack of donors, and illegal organ trafficking gets more and more serious, this infographic comes just in time. It provides some interesting answers to questions like, “How much does a liver cost in South Korea?” and “How many patients are waiting for transplants?” Click on the image for the original larger version:

Researchers at MIT have developed a method of using a basic cellphone coupled with a cheap and simple plastic device clipped onto the screen to estimate refractive errors and focal range of eyes.
Because of its simplicity, and the fact that soon just about everyone will have access to a mobile phone, eye exams may become available to the whole world at little to no cost. Read more »

People aren’t dumb. Even if — or maybe especially if — news stories don’t point out the limitations of observational studies and the fact that they can’t establish cause-and-effect, many readers seem to get it.
Here are some of the online user comments in response to a CNN.com story that is headlined, “Coffee may cut risk for some cancers“:
* “I love how an article starts with something positive and then slowly becomes a little gloomy. So is it good or not? I’m still where I was with coffee, it’s all in moderation, it ain’t gonna solve your health woes.”
* “The statistics book in a class I’m taking uses coffee as an example of statistics run amuck. It seems coffee has caused all the cancers and cures them at the same time.” Read more »

In cancer treatment, detection of a tumor in an early stage markedly increases the chance of favorable outcomes.
Can the much-aligned blood thinner, warfarin, occasionally help in early detection of cancer?
Few pharmacologic agents receive more bad press than warfarin. Stories, which are too numerous to count, like “Did warfarin kill my father,” can be widely found on Internet forums, search engines, and are often quoted by reluctant patients — whose numerator of bad warfarin experiences is one.
It is true that warfarin has a narrow therapeutic window — a small difference between an effective dose and dangerous dose. Read more »

Talk about a cruel trick of nature! A study funded by the National Institutes of Health (NIH) and published in the Journal of the American Medical Association (JAMA) shows that physical activity prevents weight gain in middle-aged and older women ONLY IF THEY ARE ALREADY AT IDEAL WEIGHT. Did you read that? It means that the recommended guidelines advocating 150 minutes of exercise a week isn’t sufficient to prevent weight gain in most middle-aged women.
The Harvard-associated researchers assessed weight changes associated with various levels of physical activity on 34,079 women who had been followed since 1992 in the Women’s Health Study. They stratified women as “inactive” (less than 150 minutes a week of moderate level physical activity), “intermediately active,” or “highly active” if they performed a high, strenuous level of activity. All three groups showed similar weight gain over a mean of 13 years of follow up. Read more »
