It Takes Two!

1 Two Vaccines Necessary Against Chickenpox

New research findings support the two-dose varicella (chickenpox) vaccine regimen that has been recommended in the U.S. since 2006. In an area in Connecticut, researchers from Yale University and collaborators at Columbia University found 71 cases of chickenpox in kids ages 4 or older. None of them had received two doses of the vaccine, while 93 percent had received only one dose. Seven percent of the kids had received no vaccine. "The odds of developing varicella were 95 percent lower in children who had received two doses of the vaccine compared with those who had received only one," says Eugene D. Shapiro, MD. Findings are published in Journal of Infectious Diseases.

Anti-Cancer Too

2 Green Tea May Offer Protection from Alzheimer's

Drinking green tea on a regular basis may protect you from developing Alzheimer's, as well as other forms of dementia, claim scientists at Newcastle University. "What was really exciting about this study was that we found when green tea is digested by enzymes in the gut, the resulting chemicals are actually more effective against key triggers of Alzheimer's development than the undigested form of the tea," says research leader Dr. Ed Okello. Study findings, published in Phytomedicine, also suggest that green tea may play an important role in protecting against cancer. Okello noted that digested compounds of green tea had anti-cancer properties, which significantly slowed down the growth of the tumor cells used in the experiments.

More Doses Should Be Available

3 Splitting Pills Is Dangerous

Splitting pills can be a dangerous practice that may lead to patients taking the wrong amount of medicine, say researchers from Ghent University in Belgium. BBC reports the researchers claim that splitting pills could have "serious clinical consequences." The medicine doses that are the most risky are those that have a narrow margin between therapeutic and toxic. While the research found that using a splitting device was more accurate than using scissors or a knife, the splitting device still had a 13 percent rate of error when study volunteers split eight different-sized tablets. Dr. Charlotte Verrue, who led the study, says that most tablets aren't suitable for splitting, and the solution is for more doses to become available. Findings are published in Journal of Advanced Nursing.

Guidelines Not Always Followed

4 Defibrillators Implanted Without Need

Many heart defibrillators are implanted unnecessarily, suggest researchers who took a closer look at records of 111,707 patients who received the implants from January 2006 to June 2009 at more than 1,200 hospitals in the U.S. According to New York Times, around 100,000 defibrillators are implanted each year in the U.S. Researchers learned that 22.5 percent of patients receiving defibrillators don't meet the established guidelines for needing the device. Hispanics and blacks were more likely than whites to receive defibrillators they most likely didn't need. The surgery to implant the high-tech defibrillators, which jolt the heart back into a normal rhythm when needed, costs about $35,000.

Incorrect or Incomplete Videos

5 YouTube Isn't a Good Place to Learn CPR

"Does this also mean that we shouldn't trust the YouTube brain surgery lessons either?"
- Mark in the comments

Almost two of three YouTube videos teaching CPR (cardiopulmonary resuscitation) give incorrect information, say researchers. MSNBC reports that researchers found 52 YouTube videos that teach CPR. Of those 52 videos, half were uploaded by people without apparent health credentials. MSNBC writes that nearly two-thirds of the videos either incorrectly described CPR chest compressions rate or completely left out that detail. Plus, 57 percent didn't fully reveal to viewers how deep the chest compressions should be. Researchers say that another gap in the CPR videos is that only a few covered hands-only CPR (no mouth-to-mouth), performed by bystanders when adults suddenly become unresponsive.
