Acetaminophen may not relieve back pain

Doctors often suggest taking acetaminophen for low back pain relief. But according to a new study, the popular painkiller isn’t any more effective in alleviating an aching back than letting the pain naturally subside.

A study published Thursday in The Lancet found patients who took acetaminophen for low back pain had the same recovery time as those who took a placebo, or sugar pill. The study was partially funded by GlaxoSmithKline, a company that manufactures drugs containing acetaminophen.

Researchers in Australia looked at 1,643 patients with acute low back pain. Each was assigned to a different group for the experiment. The first group of 550 patients took six 665-milligram tablets of acetaminophen a day as well as one to two placebo tablets.

Genetics play a bigger role than environmental causes for autism

Genetics plays more of a role in the development of autism than environmental causes, according to new research published Sunday in Nature Genetics.

The study found that 52% of autism risk comes from common genes, while only 2.6% are attributed to spontaneous mutations caused by, among other things, environmental factors.

“These genetic variations are common enough that most people are likely to have some,” said Joseph Buxbaum, a researcher at the Mount Sinai School of Medicine and one of the lead authors on the study. “Each one has a tiny effect on autism risk, and many hundreds or thousands together make a significant risk.”

Babies want to speak as early as 7 months

Babies want to speak as early as 7 months

Babies usually start speaking by their first birthday. But new research suggests talking to your baby stimulates his brain well before she utters those first words.

For the study, published Monday in the journal Proceedings of the National Academy of Sciences, the authors compared how 7- and 11-month-old babies from English-speaking families processed sounds from English and Spanish.

Researchers at the University of Washington looked at 57 babies who were 7, 11 and 12 months old. The babies sat in an egg-shaped, noninvasive brain scanner that measures brain activation and listened to speech sounds played over a loudspeaker.

The researchers examined patterns of brain activation in areas of the brain that analyze sound, as well as areas that plan the motor movements required to produce speech.

5 studies you may have missed
Eating more fruits and vegetables won't help you lose weight if you don't reduce the number of calories you're eating overall.

5 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.

Eating more fruits and veggies won’t make you lose weight
American Journal of Clinical Nutrition

We’re often told to eat more fruits and vegetables, but the chances that you’ll lose weight just by eating more of these foods are slim. New research suggests increased fruit and vegetable intake is only effective for weight loss if you make an effort to reduce your calorie intake overall.

In other words, you need to exercise or consume fewer calories to shed those pounds.

Pesticide exposure during pregnancy may increase autism risk

Scientists have long hypothesized that chemicals found in our environment play a role in causing autism. Research published this week in Environmental Health Perspectives supports that theory, finding children whose mothers are exposed to agricultural pesticides during pregnancy may be at increased risk for autism spectrum disorders, or ASD.

Researchers at the University of California, Davis, looked at the medical records of 970 participants. They found pregnant women who lived within a mile of an area treated with three different types of pesticides were at a two-thirds higher risk of having a child with ASD or developmental delays. These pesticide-treated areas included parks, golf courses, pastures and roadsides.

The study investigated the use of three classes of pesticides: organophosphates, which include the widely used insecticide chlorpyrifos, as well as pyrtheroids and carbamates.

1 in 4 Americans living with diabetes don't know

The number of Americans with diabetes continues to rise - there are now more than 29 million adults living with the disease, according to the latest data released by the Centers for Disease Control and Prevention on Tuesday. That’s 3 million more than the last time the CDC released diabetes statistics in 2011.

The CDC estimates that a quarter of these adults living with diabetes in the United States don’t even know they are sick, meaning they haven't been diagnosed.

An additional 86 million American adults have what’s called “pre-diabetes,” which means that their blood sugar levels are higher than normal, but not yet on the level of diabetes. And nearly all – 90% - of these Americans do not know they are headed down a dangerous road. The CDC estimates that 15 to 30% of people with pre-diabetes will develop diabetes within five years if they don't exercise and lose weight.

“These new numbers are alarming and underscore the need for an increased focus on reducing the burden of diabetes in our country,” Ann Albright, the CDC’s director of the division of diabetes translation, said in a press release. “It’s urgent that we take swift action to effectively treat and prevent this serious disease.”

People with diabetes are at increased risk for blindness, kidney failure, heart disease and stroke. The disease is usually linked to obesity, lack of physical activity and/or a family history of the disease.
