For hundreds of years people have practiced the Chinese martial art of Tai Chi for its many health benefits. Researchers who study Tai Chi say it can help reduce blood pressure, decrease anxiety, improve flexibility and much more. For these reasons, some doctors at Mayo Clinic have embraced Tai Chi and are teaching it to their patients.

From Wachter's World:

"In 1984, one resident even wrote a letter to the New England Journal of Medicine called “Ripping and Filing Journal Articles,” taking the Journal to task for its habit of beginning an article on the back of the last page of the previous one (which meant the page needed to be photocopied if you wanted to tear both articles out of your personal copy of the journal). Fair point, but talk about a resident who needed to get a life.

Today, as in so many other parts of our lives, the computer, with its magical access to the universe of on-line resources, has democratized the learning of clinical medicine. At UCSF, by the time morning rolls around, the students and interns have often already read the on-line UpToDate synopsis of the topic at hand, and may be as capable of teaching the resident (or attending) about it as visa versa."

Driving while talking on a cell phone is extremely hazardous for most people.

Only a tiny fraction of “supertaskers” can do both simultaneously without ill effect - 2.5% of people studied could successfully drive and use a cell phone at the same time.

It took most people 20% longer to hit the brakes and increased following distances 30%, meaning they failed to keep pace in the simulator with virtual traffic. Also, their memory performance dropped 11% and their ability to do the math fell 3%.

A study included M.R.I.’s of the hips of 21 professional hockey players and 21 college players. They showed abnormalities in 70 percent of the athletes, even though these hockey players had no pain or only minimal discomfort that did not affect their playing. More than half had labral tears, rips in the cartilage that stabilizes the hip.

“M.R.I.’s are so sensitive,” Dr. Musahl said. “They frequently show little tears or fraying everywhere. And it is very, very common to have a small labral tear in your hip — it doesn’t mean you have to have the particular symptoms.”

Mayo Clinic emphasizes living donor kidney transplants as the best option for patients. Martin Mai, M.D., nephrologist at Mayo Clinic offers information about living donation, statistics, including the fact that living donor kidneys last longer. Half of living donor kidneys transplanted today will still be functioning 25 years from now, whereas half of cadaveric kidneys will fail in the first 10 years.

Candy and Ellen's Story.

The rapid expansion of the Internet has increased the ease with which the public can obtain medical information. Most research on the utility of the Internet for health purposes has evaluated the quality of the information or examined its impact on clinical populations. Little is known about the consequences of its use by the general population.

Health-related Internet use was associated with small but reliable increases in depression (i.e., increasing use of the Internet for health purposes from 3 to 5 days per week to once a day was associated with 0.11 standard deviations more symptoms of depression, P = 0.002).

Using the Internet for health purposes was associated with increased depression. The increase may be due to increased rumination, unnecessary alarm, or over-attention to health problems.

In contrast, using the Internet to communicate with friends and family was associated with declines in depression.
