Five studies you may have missed

Here's a roundup of five medical studies published this week that might give you new 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.

Autism may begin in the womb
Journal: New England Journal of Medicine

With this week's CDC announcement that 1 in 68 children in the United States has an autism spectrum disorder, there's even more reason to look at how and when this condition develops.

A new study suggests that there are changes in a developing child's brain even before he or she is born that are associated with autism. Researchers found patches of abnormalities in several brain areas, including those involved in social, emotional, communication and language functions.

But this is a small study, which looked at the brain tissue of only 22 children.

"Although interesting differences in brain architecture were found, questions regarding underlying mechanisms remain unanswered," says Zack Warren, director of  the Treatment and Research Institute for Autism Spectrum Disorders at Vanderbilt University Medical Center, who was not involved in the study.

It's not safe to the pee in the pool
Journal: Environmental Science & Technology

There are two types of swimmers, an old saying goes: Those who pee in the pool, and those who say they don't. A new study may create a new kind - those begging the rest of us to stop.

Chemists found that mixing urine with sweat and chlorine in water created two compounds: trichloramine (NCl3) and cyanogen chloride (CNCl). NCl3 is associated with lung problems, and CNC1 may affect the lungs, heart and central nervous system, according to the American Chemical Society.

"Swimmers can improve pool conditions by simply urinating where they’re supposed to — in the bathrooms," the ACS concluded.

Lower back pain is a major cause of disability
Journal: Annals of Rheumatic Diseases

Lower back pain is common, affecting approximately 1 in 10 people around the globe. But you may not realize how disabling it can be.

Researchers pooled information from 117 studies in 47 different countries and 16 world regions. They concluded that lower back pain is the leading cause worldwide of years lost to disability. It was No. 1 among 291 conditions analyzed in this study.

Not all lower back pain comes from working, but many people do get it on the job. So what should people do?

“Exercise may be the most effective way to speed recovery from low back pain and help strengthen back and abdominal muscles. Maintaining and building muscle strength is particularly important for persons with skeletal irregularities,” according to the National Institute of Neurological Disorders and Stroke.

Bariatric surgery does more than change your stomach size
Journal: Nature

Gastric bypass surgery reduces the size of an obese patient's stomach in hopes of making them eat less. But new research suggests the underlying chemical changes that occur in the patient's digestive system after surgery may be just as important - if not more so - to their ability to lose weight.

"We have more bacteria in our guts than we have cells in our bodies," study author Randy Seeley told USA Today. "Those bacteria and their interaction with our bodies is really important."

Scientists spent four years analyzing gastric bypass surgeries in mice. After bariatric surgery, our bodies increase liver bile acids that bind to a nuclear receptor called FXR, according to the study. When researchers removed the FXR receptor from the mice, they lost less weight than other mice who had undergone a gastric bypass procedure. The scientists also noticed changes in the mice's gut bacteria.

The results of this study could lead scientists to develop new ways to mimic the effects of bariatric surgery without physically altering the stomach.

Smoking bans seem to be working
Journal: The Lancet

Rates of pre-term births and hospital admissions for children with asthma have dropped significantly since many states here and countries in Europe have introduced smoke-free legislation.

Researchers analyzed 11 studies and determined that the rates were reduced in the year after the laws went into effect. This shows a clear link between a reduction in second-hand smoke and a decrease in these conditions, they say.

"Together with the known health benefits in adults, our study provides clear evidence that smoking bans have considerable public health benefits for perinatal and child health, and provides strong support for WHO recommendations to create smoke-free public environments on a national level," Dr. Jasper Been told ScienceDaily.

  5. Blame Republicans For Obamacare

    Blame the republicans for Obamacare. If the republicans has introduced a single payer system (the ONLY system that will allow us, as an entire nation, to negotiate better health care prices), then we wouldn't have to deal with Obamacare today. But since the republicans introduced NOTHING (of substance) to help contain health care prices, we now have Obamacare. I blame the republicans for Obamacare. After all it was their idea, supported by the Heritage Foundation, and implemented by Mitt Romney.
