So I've been writing this blog for almost a year now. I hope
that I have brought you some insight or at least made you think a little about
your health and the amazing breakthroughs of the Biomedical Engineering
community. You guys have also taught me to always be critical of my sources,
and to present information that you want to know about. I really enjoy writing
these blog posts, and I hope that I can continue to teach you something each
week.
I found an article on ABC news titled the 5
Health Scares You Can Ignore, that I thought I would share three of them
with you all.

1. Cellphones
give you brain cancer. This rumor was largely caused by media hype in 1993.
Dozens of studies
were done to observe the correlation between using a cellphone and getting a
brain tumor, but none were found. Your cell phones givesoff the same amount of
radiation as an AM radio or television. John Moulder,
a professor of radiation oncology at the University of Wisconsin-Madison, says
that there is no
evidence that radio frequencies can cause a change in human cells. If
you're still worried, try switching to a service with more towers so your cell phone
doesn't have to work as hard to prevent dropped calls. Image Credit: Black Hawk County Sheriff's Office

Vaccines
cause Autism. In 1998 a study was published by Andrew
Wakefield concluding that MMR (measles, mumps, and rubella) vaccine
was the cause of developmental and social disabilities in children. Again, the
media response was swift and even celebrities such as Jenny
McCarthy spoke out against vaccination. As the incidence of measles in
England from 56 in 1998 to 884 in 2008, the Centers for Disease Control and
Prevention and the Nation Institute of Health convened a panel of experts to
examine Wakefield's claim. Fortunately, the publishing journal retracted
Wakefield's study in 2010 after finding that the study only included 12
children, blood samples were purchased from friends of the researcher, and
Wakefield had a patent for a rival measles vaccine which claimed to be
safer…can you say financial incentive? Vaccines are not
only safe, but they help prevent the contraction and spread of a wide
variety of dangerous diseases. It
was hard to get a picture of a child who wasn't crying. He's a tough little
kid. Image Credit: World Pneumonia Day

Plastic
water bottles are unsafe. I think this hits home for most people. I always
cringe a little when I see people refilling water
bottles and I know people who are stocked up on reusable water bottles. In
1998 (apparently the year of outrageous articles), a study was published
claiming that low doses of bisphenol A (BPA) caused reproductive and
developmental abnormalities in rats. Bisphenol A is used in the production of
hard plastics and in the coating of aluminum cans. Terrifying headlines
followed a Consumer Reports article exposing the chemical. Dozens of research
groups found BPA leaching from the plastic into food and water. The EPA set an
"acceptable daily intake" level at 3.6 micrograms per day based on a 160- pound
male, and the research groups found that the maximum average intake was
one-tenth of a micro-gram. Most water bottles are actually made of polyethylene
terephthalate (PET). You can check this by looking for the recycling number of
1 on the bottle. BPA has the recycling number of 7. The research done with rats
has been poorly replicated in humans because we metabolize BPA much more
efficiently and the acceptable daily intake for humans in one-thousandth of the
amount it takes to show any effects (weight loss) in rate. "Adverse
effects have never been observed in humans," says Michael Karmin, Ph.D, a
toxicology professor emeritus at Michigan State University.

Please let me know if there is anything you want to learn
more about. This can include explaining the science behind a new discovery,
medical/science mysteries that plague everyday life or just more information
about something biomedical. I'm always on the lookout for more ideas and I
would love to know more about your interests.
