In response to the opioid epidemic that has swept the country, the Centers for Disease Control and Prevention released long-anticipated guidelines on prescribing opioid painkillers such as OxyContin and Percocet.

They were published Tuesday in JAMA, the Journal of the American Medical Association.

TERRY GROSS, HOST:

If the high-pitched whir of a dentist's drill as it bores into your molar terrifies you, good news! There could be fewer fillings in your future. A painless way to prevent cavities in adults is gaining traction.

When she was 17, Tracey Helton Mitchell was prescribed an opioid pain killer after getting her wisdom teeth extracted. The medicine helped her deal with the pain related to the extraction, but when the prescription ran out, her desire for its euphoric high remained. That's when she turned to heroin.

Carla used to get dialysis a couple of times a week at the public hospital in Indianapolis, Eskenazi Hospital. She would sit in a chair for hours as a machine took blood out of her arm, cleaned it and pumped it back into her body.

Then one day in 2014, she was turned away.

Even though her lungs were full of fluid, the doctors said her condition wasn't urgent enough to treat that day, she says. "I explained to the doctors that I couldn't breathe," she recalls, "and they told me it wasn't true, that I had to wait three more days."

Though the majority of Americans have a primary care doctor, a large number also seek treatment at urgent care centers, statistics show. For many people, the centers have become a bridge between the primary care doctor's office and the hospital emergency room.

Something was wrong with Nat.

I got the call about my 25-year-old severely autistic son just as I was parking, about to meet a friend for coffee. It was from Richard, the day program director. Like many adults with significant disabilities, Nat spends his weekdays at a day program, an organization that helps his employer so that he can work — he does carriage return at a local Shaw's. When Nat is not working at Shaw's, he is out in the community with support staff and other individuals in his program, volunteering at Meals on Wheels and various activities.

Flint, Mich., isn't the only American city with a lead problem. Though the health crisis in Flint has highlighted the use of lead in water pipes, author David Rosner tells Fresh Air's Terry Gross that lead, which is a neurotoxin, can be found throughout the U.S. on walls, in soil and in the air.

"The problem with lead is that it's now really everywhere, and we've created a terribly toxic environment in all sorts of ways," he says.

The Zika virus is a health threat not just to Latin America, but also to parts of the U.S. It's already a problem in Puerto Rico where there are nearly 120 cases so far, including five pregnant women. That's a concern, because Zika may be involved in causing birth defects.

One of the best ways to understand Zika virus might be to deliberately inject it into volunteers.

That idea may sound a little crazy, but it's not unprecedented. And some researchers are hoping the approach could help speed up the search for an effective Zika vaccine.

Right now, a bunch of labs are pursuing different ways of making a vaccine against Zika, mostly because of the concern that the virus might be linked to the birth defect called microcephaly.

In a study powered by the labor of medical students, my colleagues and I found that two-thirds of clinical trials led by scientists at our finest academic institutions didn't share their results publicly within two years of the study's completion.

Moreover, none of these research institutions has a good record of sharing results. Many are much worse than the average.

As public health officials struggle to contain the Zika virus, science writer Sonia Shah tells Fresh Air's Dave Davies that epidemiologists are bracing themselves for what has been called the next "Big One" — a disease that could kill tens of millions of people in the coming years.

Midway through Matt Keil's second deployment in Iraq, he came home and married his fiancee, Tracy, in 2007.

He had two weeks R&R; no time for a honeymoon.

Before he went back to war the couple had the sort of conversation unique to newlyweds in the military. "I told her if you get a phone call that I'm injured, I'm probably fine," Matt says. "But if they come to the apartment or to your work in person, then I'm dead."

U.S. manufacturers of medical devices started 2016 with a windfall — a two-year suspension of a controversial tax on their revenue.

Dr. Paul Kalanithi was preparing to wrap up his medical residency in neurosurgery when, in 2013, a CT scan revealed tumors throughout his body. He had stage 4 lung cancer.

In his last two years of life, he continued caring for patients. He and his wife became parents. And Kalanithi, a gifted writer, wrote a book, When Breath Becomes Air, a reflection on being a doctor with a terminal illness.

He died March 9, 2015. He was 37 years old.

The odds of getting Alzheimer's disease or other forms of dementia are declining for people who are more educated and avoiding heart disease, a study finds. The results suggest that people may have some control over their risk of dementia as they age.

This isn't the first study to find that the incidence of dementia is waning, but it may be the best so far. Researchers looked at 30 years of records from more than 5,000 people in the famed Framingham Heart Study, which has closely tracked the health of volunteers in Framingham, Mass.

In the summer of 2014, a 23-year-old pregnant woman entered the military hospital at Bagram Air Field in Afghanistan with a cut on her left cheek. The wound had been stitched up elsewhere, but she still wasn't quite right.

She said she'd been hit in the face by a ricochet back in her home village. What hit her exactly, she couldn't say for sure. She was upset, though, because the vision was bad in her left eye, even though there had been no apparent trauma to it.

The sighs we notice usually accompany emotions like relief or discontent. But our brains are programmed to make us heave an unconscious sigh every five minutes or so — no matter how we feel.

"Sighing is vital to maintain lung function," says Jack Feldman, a brain scientist at UCLA. These periodic deep breaths reinflate tiny air sacs in the lungs that have gone flat. But the brain circuitry behind those reflexive sighs has been a mystery.

At 46 years old, Oliver Bogler's reaction to a suspicious lump in his chest might seem typical for a man. He ignored it for three to four months, maybe longer. "I couldn't really imagine I would have this disease," Bogler says. But when he finally "grew up" and went to the doctor, he was pretty quickly diagnosed with invasive breast cancer.

Would it be ethical for scientists to try to create babies that have genetic material from three different people? An influential panel of experts has concluded the answer could be yes.
