5 studies you may have missed

Here's a roundup of five medical studies published this week that might give you insights into your health, mind and body. Remember, correlation is not causation, so if a study finds a connection between two things, it doesn't mean that one causes the other.

Low tolerance for pain? Blame your parents
Presented at the American Academy of Neurology's annual meeting

Researchers believe they've identified four genes that are responsible for your ability to tolerate pain. In their study, they asked 2,721 people with chronic pain to rate their pain on a scale from 1 to 10, 10 being the most painful. Researchers then grouped the participants according to low-pain, moderate-pain or high-pain ratings, and identified which genes were more prevalent in each group.

“Chronic pain can affect every other part of life,” study author Dr. Tobore Onojjighofia said in a statement. “Finding genes that maybe play a role in pain perception could provide a target for developing new therapies and help physicians better understand their patients’ perceptions of pain.”

Prenatal vitamin D could affect your baby's teeth
Journal: Pediatrics

Skipping your prenatal vitamin D supplements could have unintended consequences for your baby's teeth. Researchers at the University of Manitoba in Canada found children born to moms with low levels of vitamin D in their blood during pregnancy had a greater risk of developing cavities as a toddler.

Vitamin D helps strengthen tooth enamel, and a deficiency can lead to defects, which can leave the teeth vulnerable to cavities. Most organizations recommend taking a prenatal supplement that has 400 international units of vitamin D. The vitamin can also be found in fish, fortified milk and orange juice, and some cereals.

Feeling sick? Get some sleep
Journal: Sleep

Your mom was right (again). The best thing for you when you're sick is probably sleep.

After conducting two studies, researchers concluded extra sleep helps enhance fruit flies' immune systems' response to and recovery from infection. They believe these findings may apply to humans as well.

In the first study, scientists deprived one group of flies of sleep before infecting them with bacteria. Both the sleep-deprived flies and the control group slept while infected, but the sleep-deprived flies had a better survival rate. The researchers say the sleep-deprived flies slept longer while infected than the control group, possibly enhancing their immune system response.

In the second study, researchers used drugs to make one group of flies sleep longer while infected than another. The group that slept longer had a better survival rate. They were also able to clear the bacteria from their bodies more quickly.

"The take-home message from these papers is that when you get sick, you should sleep as much as you can; we now have the data that supports this idea," study author Julie Williams said in a statement.

3,000 types of bacteria live on your money
New York University's Dirty Money Project

This research hasn't been published, but it was too gross not to share. Geneticists at New York University are examining dollar bills to find out how much bacteria you're carrying around in your wallet. Turns out it's a lot.

They identified 3,000 types of bacteria on 80 $1 bills from an unnamed Manhattan bank, and say that's only about 20% of the nonhuman DNA they found. The identified bacteria are known to cause everything from acne to ulcers.

Basically, "a body-temperature wallet is a petri dish," Philippe Etienne, managing director of Innovia Security Pty Ltd., told the Wall Street Journal.

Cholesterol meds aren't a free pass to eat what you want
Journal: JAMA

People who take statins, medication commonly used to lower bad cholesterol levels, eat more today than statin users did 10 years ago, researchers say.

Statin users' caloric intake in 2009-2010 was 9.6% higher than statin users' intake in 1999-2000, the scientists found after analyzing data from 27,000 U.S. adults. And while past statin users used to consume fewer calories and less fat than their non-statin-taking peers, that's no longer the case. It appears people today may believe statins are a free pass to eat what they want without high cholesterol.

"The importance of dietary composition may need to be re-emphasized for statin users," the study authors concluded.

    Keep sending me your dirty money. I like money! I kissed my way up to CEO at a health insurance company. Now I take over $1,000,000 of your health care dollars for NO VALUE ADDED to your health care. And that’s just me. Now think about how many other CEOs, VPs, Directors, Managers, etc. are at my company alone. Now multiply that by thousands of others at hundreds of other health insurance companies. From 10 to 25% of your health care dollars go towards administration that adds NO VALUE to your health care. But my company’s PAC dollars will continue to fool you little people into thinking that a single payer system will be bad. Little people like you are so easy to fool. Little people also don’t realize that a single payer system is the ONLY system that would allow little people (as an entire country) to negotiate better health care prices. Little people don’t realize that the Medical Cartels already know that. And that is the reason why the Medical Cartels spend so much PAC money from the hospitals and doctors lobbying against a single payer system. Some little people say that a single payer system would cost you little people more. But if that were true, then wouldn’t the hospitals and doctors WANT that extra money? Yes they would. So why do the Medical Cartels lobby against a single payer system? It’s because the Medical Cartels know it would allow little people to negotiate better health care prices. And that’s what the Medical Cartels are afraid of. Period.
    But us big wigs at insurance companies, hospitals, and pharmacy companies don’t ever need to worry about health care no matter what it costs. We get our health care paid for one way or another by you little people. And we get the little people that work at our companies to contribute to our PACs. And us big wigs say it’s to protect the little peoples’ jobs. But in reality it would be in the little peoples’ best interest to NOT contribute to the PAC. Again, little people are so easily fooled. I won’t ever have to worry about losing my job with so many little people being brain washed by the Medical Cartels’ PAC money. Not only that, the Medical Cartels’ PAC money is used to elect so many republicans that will never allow a single payer system. Republicans have always fought against any meaningful health care reform. But that’s what our Medical Cartels’ PACs pay them for. Politicians can be bought so easily.
    Pretty soon the only people that will be able to afford health care is us big wigs. And that’s the way it should be. We don’t want you little people using up the resources when we need them. And once again, I thank you little people for capping my SS tax at the $117,000 level. Now I only pay 1.17% SS tax and you little people pay 6.2%. Also, thank you for extending my tax breaks. I’m using the extra money on my vacation houses.

      What do you hope to achieve by posting this epistle over and over? Do you really think anyone reads such drivel? Have you ever heard of paragraphs? Or that brevity is the soul of wit?
