Disinfect All ICU Patients To Reduce 'Superbug' Infections

To fight antibiotic-resistant staph germs like these, a study suggests disinfecting the skin of all intensive care patients.

Originally published on Thu May 30, 2013 3:41 pm

Hospitals can sharply reduce the spread of the drug-resistant bacteria in their intensive care units by decontaminating all patients rather than screening them and focusing only on those found to be infected already, researchers reported Wednesday.

Research Reveals Yeasty Beasts Living On Our Skin

Fungi (cyan) surround a human hair within the skin. A study in the journal Nature shows the population of fungi on human skin is more diverse that previously thought.

Scientists have completed an unusual survey: a census of the fungi that inhabit different places on our skin. It's part of a big scientific push to better understand the microbes that live in and on our bodies.

"This is the first study of our fungi, which are yeast and other molds that live on the human body," says Julie Segre, of the National Human Genome Research Institute, who led the survey.

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.

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.

Gut Bacteria's Belch May Play A Role In Heart Disease

More than just a tenant: Enterococcus faecalis thrives in the human intestine with a varied jumble of other bacteria that help us digest food.

Originally published on Mon September 9, 2013 9:38 am

Scientists have discovered what may be an important new risk factor for heart disease. And here's the surprising twist: The troublesome substance seems to be a waste product left behind by bacteria in our guts as they help us digest lecithin — a substance plentiful in red meat, eggs, liver and certain other foods.

Doctors say the research further illustrates the complicated relationship we have with the microbes living inside us, and could lead to new ways to prevent heart attacks and strokes.

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.

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. "It would not be ethical to do it today."
