Rob Stein — Wed, 15 May 2013 16:13:00 +0000

Scientists say they have, for the first time, cloned human embryos capable of producing embryonic stem cells.

The accomplishment is a long-sought step toward harnessing the potential power of embryonic stem cells to treat many human diseases. But the work also raises a host of ethical concerns.

"This is a huge scientific advance," said Dr. George Daley, a Harvard stem cell scientist who wasn't involved in the work.

Parents' Saliva On Pacifiers Could Ward Off Baby's Allergies

That word "microbiome" — describing the collection of bacteria that live in and on our bodies — keeps popping up. This time, researchers say that children whose parents clean their pacifiers by sucking them might be less likely to develop allergic conditions because of how their parents' saliva changes their microbiomes.

That's the word from a small study of 184 Swedish babies published in this week's issue of the journal Pediatrics.

How Much Does It Hurt? Let's Scan Your Brain

Rob Stein — Wed, 10 Apr 2013 23:17:00 +0000

Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.

The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.

Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.

"We all have trouble communicating our pain and other feelings under different circumstances," says Yukiyasu Kamitani, a researcher at the ATR Computational Neuroscience Laboratories in Kyoto, Japan.

Philosophers, poets and psychologists have long shared a fascination with dreams.

China's Air Pollution Linked To Millions Of Early Deaths

Rob Stein — Tue, 02 Apr 2013 21:25:00 +0000

More than 1 million people are dying prematurely every year from air pollution in China, according to a new analysis.

"This is the highest toll in the world and it really reflects the very high levels of air pollution that exist in China today," says Robert O'Keefe of the Health Effects Institute in Boston, who presented the findings in Beijing this week.

Alarm has been growing in recent years about the air in China.

Bioethics Panel Warns Against Anthrax Vaccine Testing On Kids

Rob Stein — Tue, 19 Mar 2013 07:16:00 +0000

A controversial government proposal to test the anthrax vaccine in children would be unethical without first conducting much more research, a presidential commission concluded Tuesday.

"The federal government would have to take multiple steps before anthrax vaccine trials with children could be ethically considered," Amy Gutmann, who chairs the Presidential Commission for the Study of Bioethical Issues, tells Shots.

Americans More Distracted Behind The Wheel Than Europeans

Rob Stein — Thu, 14 Mar 2013 17:10:00 +0000

U.S. drivers are much more likely than Europeans to drive while distracted, federal health officials report Thursday.

Nearly 69 percent of Americans who drive say that they talked on their cell phones while driving at least once in the previous month, according to a survey by the Centers for Disease Control and Prevention.

That's a lot higher than what was reported by Europeans in another survey. Only 21 percent of British drivers reported chatting on their cell phones while behind the wheel, for example.

Infections With 'Nightmare Bacteria' Are On The Rise In U.S. Hospitals

MELISSA BLOCK, HOST:

This year's flu vaccine looks like it's not doing much to protect older people. New numbers in the Centers for Disease Control and Prevention indicate that the vaccine has only been effective about a quarter of the time for people 65 and older. NPR's Rob Stein joins me to explain what that means. And Rob, tell us more about these numbers coming from the CDC.

Flu Vaccine Has Been Feeble For Elderly This Season

Rob Stein — Thu, 21 Feb 2013 21:54:00 +0000

This year's flu vaccine appears to be doing a unusually poor job of protecting the elderly, federal health officials reported Thursday.

Overall, this year's flu vaccine appears to be only about 27 percent effective for people ages 65 and older, the Centers for Disease Control and Prevention reports in this week's Morbidity and Mortality Weekly Report.

But, perhaps more important and more concerning, it looks like it's only about 9 percent effective in protecting people 65 and older against the

Richard Kessinger loves to hit the gym. But some days he needs a little something to get him pumped up for his weightlifting routine.

"You might be a little bit sore. You might be tired. You might have had too many beers the day before," says Kessinger, 23, of Arlington, Va. "So you might start putting up a set and you get a few reps in and you're like, 'I'm not feeling this. I can't keep going.' "

So Kessinger sometimes swallows something called DMAA, which is short for dimethylamylamine.

Aging Poorly: Another Act of Baby Boomer Rebellion

Rob Stein — Mon, 04 Feb 2013 22:32:00 +0000

Baby boomers have a reputation for being addicted to exercise and obsessed with eating well.

But that story didn't jibe with what physician Dana E. King and his colleagues see walking through the door of their family practice every day in Morgantown, W.Va.

"The perception is that the baby boomers are very active — they are, you know, climbing up mountains, and they are a very healthy bunch," says King, a professor in the department of family medicine at the West Virginia University School of Medicine.

To Fight Addiction, FDA Advisers Endorse Limits On Vicodin And Similar Painkillers

Rob Stein — Fri, 25 Jan 2013 21:47:00 +0000

A key federal panel Friday recommended placing new restrictions on Vicodin and similar prescription painkillers.

At the conclusion of an emotional two-day hearing, the Food and Drug Administration advisory committee voted 19-10 to recommend the agency change how drugs that contain the opioid hydrocodone are classified as controlled substances.

If the agency goes along with the panel's recommendation, which is typical but not required, the drugs would be more stringently regulated, moving to so-called Crohn's disease, a chronic digestive disorder, since he was a teenager.

"So he was prescribed, you know, Lortab, or Vicodin or whatever.

Federal healthy officials said Friday there are some early signs this year's flu season may be easing in some parts of the country. But they stressed it's far too early to tell whether the flu season has peaked.

The number of states reporting widespread flu activity is up to 47, according to the Centers for Disease Control and Prevention. But flu activity nationally fell slightly in the CDC's most recent data.

Wake-Up Call: FDA Pushes Drugmakers To Weaken Sleeping Pills

Rob Stein — Thu, 10 Jan 2013 18:25:00 +0000

The Food and Drug Administration announced Thursday that it was requiring companies that make Ambien and similar sleeping pills to sharply cut the doses of the drugs.

The agency says it is taking the step for the brands Ambien, Ambien CR, Edluar and Zolpimist, as well as generic versions of Ambien, because tests showed the active ingredient in the medications, zolpidem, stays in the body longer than had been thought.

Can You Get A Flu Shot And Still Get The Flu?

Katie Alonzo was stunned when doctors told her they couldn't get a drug her 10-year-old daughter, Abby, was taking to fight lymphoma.

"When a doctor says, 'This is what you need to take.' And then all of a sudden somebody tells you, 'Well, that is what you need to take but this isn't available so we're going to try this instead,' it's very scary," say Alonzo, who lives in Port St.

When Sarah Gardner was 34, she started getting really worried about whether she'd ever have kids.

"I bought this kit online that said that they could tell you your ovarian reserve," Gardner, now 40, says. These kits claim they can tell women how long their ovaries will continue producing eggs and how much time they have left to get pregnant.

"Well, mine said, 'we advise really you have a baby now.' Well, sadly that letter arrived three weeks after I just split up with my long-term partner.

Bill Sneddon had a feeling he was in trouble when his doctor called with his latest test results.

"I just had a premonition that something's not right," said Sneddon, 68, of Ocean Township, N.J.

And, sure enough, Sneddon's instincts were right. He had prostate cancer.

"Well, it's an eye-opener, you know. I didn't know if I had to buy a yard sale sign, you know," he said. "It's a shocking thing ... It always happens to someone else."

After getting over the shock, Sneddon, a retired police chief, quickly started investigating his options, including surgery and radiation.

Geneticists Breach Ethical Taboo By Changing Genes Across Generations

Freezing Eggs To Make Babies Later Moves Toward Mainstream

Rob Stein — Fri, 19 Oct 2012 09:00:00 +0000

Doctors who specialize in treating infertility are making a big change in their position on a controversial practice. The American Society for Reproductive Medicine (ASRM) has concluded that freezing women's eggs to treat infertility should no longer be considered "experimental."

The group plans to officially announce the change on Monday.

More and more women are using frozen eggs to try to have babies. Some older women use frozen eggs donated by younger women.
