Most hospitals around the country aren't doing a good job of helping new moms who want to breast-feed, researchers report Tuesday in the journal Morbidity and Mortality Weekly Report.

Several common practices at the institutions may actually prevent moms from sticking with breast-feeding for six months — the duration thought to be most healthful for babies.

Correctional facilities have to provide health services to people who are incarcerated, but that doesn't mean the care is free of charge. In most states, inmates may be on the hook for copayments ranging from a few dollars to as much as $100 for medical care, a recent study finds.

Say you're a Midwestern farmer in a hospital bed, recovering from surgery or a major illness. It's time for the nurse's check-in, but there's no knock on the door.

At Mercy Hospital in St. Louis, a camera attached to the wall over the foot of the bed whirls around, as a video monitor next to the camera lights up to show a smiling face with a headset on.

"Good afternoon, this is Jeff with SafeWatch," the smiling face says. "Just doing my afternoon rounds."

As a doctor who provides medical care to Boston's homeless population, James O'Connell and his colleagues are used to working in unusual locations. "We are basically visiting them in their homes, which are often under bridges, down back alleyways [and] on park benches," O'Connell tells Fresh Air's Terry Gross. "It's been an education for us over these years."

Before they were removed following an outcry over privacy, backscatter X-ray security scanners at airports also raised worries among some travelers and scientists about exposure to potentially harmful radiation.

Angelina Diaz-Ramirez had no idea a surgeon was about to cut open her chest. The 50-year-old had been rushed to the hospital from the California field where she worked picking green beans. Doctors said she had a heart attack and that they would do surgery to install a pacemaker.

But Diaz-Ramirez, an immigrant from Mexico, doesn't speak Spanish or English. She speaks Triqui, an indigenous language. And the hospital had no one who could translate the doctors' words for her.

"None explained anything to me," said Diaz-Ramirez. "I was scared, but I didn't have a choice."

A mind-altering drug called ketamine is changing the way some doctors treat depression.

Encouraged by research showing that ketamine can relieve even the worst depression in a matter of hours, these doctors are giving the drug to some of their toughest patients. And they're doing this even though ketamine lacks approval from the Food and Drug Administration for treating depression.

If you follow health news, by now you may have heard about a federally funded study that was stopped early because of impressive evidence that aggressively lowering blood pressure saves lives.

Children of anxious parents are more at risk of developing an anxiety disorder. But there's welcome news for those anxious parents: that trajectory toward anxiety isn't set in stone.

The Food and Drug Administration should gather more information to try to get a better sense of the safety of the Essure sterilization device, a panel of experts assembled by the agency recommended Thursday.

"To be honest, we don't know what we don't know," said Dr. Cheryl B. Iglesia of the MedStar Washington Hospital Center, who chaired the FDA's Obstetrics and Gynecology Devices Panel, summarizing frustration expressed by several members.

We know who we are: women of a "certain age" trying to hold back the assault of menopausal symptoms, and we are often desperate. Some of us remain on hormone replacement therapy. But many of us are unable to use hormones for medical reasons or by choice. As a result, droves of us turn to all sorts of treatments, everything from acupuncture to yoga to antidepressants to herbs. And surveys show most women are completely befuddled as to whether any of these treatments actually work.

As a surgeon who specializes in the care and treatment of patients with breast cancer, Elisa Port says one of the hardest parts of her job is delivering bad news to patients.

"I wish I could say it got easier as it goes along, but it certainly doesn't. ... It affects me every single time," Port tells Fresh Air's Terry Gross.

Remember Pig-Pen? The little kid from Charles Schulz's Peanuts cartoons who walked around in a cloud of dirt? Well, the human body does spew a cloud, but instead of dirt it contains millions of microorganisms.

"It turns out that that kid is all of us," says James Meadow, a microbial ecologist who led research about the microbes shadowing us during postdoctoral work at the University of Oregon. "It's just a microscopic cloud that's really hard to see."

When Portland resident Doris Keene raised her four children, she walked everywhere and stayed active. But when she turned 59, she says, everything fell apart.

"My leg started bothering me. First it was my knees." She ignored the pain, and thinks now it was her sciatic nerve acting up, all along. "I just tried to deal with it," Keene says.

At a house in West Hartford, a young man and his grandfather are watching movies. First, it's The Love Bug. Now, it's Aliens.
