Juan Flores and his family live in Galena Park, Texas, which is bordered on three sides by pipeline terminals, oil refineries, fertilizer plants and rail yards.

Flores has lived in the town of about 11,000 people just east of downtown Houston since he was 4 years old. For a while, he even served on the City Council.

Shannan Wheeler was born and raised in Baytown, Texas, an industrial suburb east of Houston that is part of the so-called chemical coast.

Houses are tucked between chemical storage tanks. Parks back up to refinery smokestacks.

Last week's mass shooting in Las Vegas posed a test for new medical residents and fellows at the University of Nevada, Las Vegas hospital. They were in their first days on the job. NPR's Rebecca Hersher met two young surgeons.

Dr. Christopher Fisher was working at Sunrise Hospital and Medical Center just off the Las Vegas strip on Sunday evening when the patients starting arriving.

"It did look a bit like a war zone, can't say that it didn't," he remembers. "Frantic families, blood in the hallways."

People came in so grievously injured and so many at a time that Fisher, who is the medical head of trauma services for the hospital, and his colleagues used markers, writing directly on patients, to do triage.

Flu symptoms can be more severe when you're pregnant, landing women in the hospital, threatening their lives and even leading to preterm birth or miscarriage. The virus is a risk to the woman and the baby.

So, it's particularly important that people who are pregnant get the flu vaccine. And it's also important that the effects of those vaccines be studied in pregnant women.

On the first sunny day in Houston after about 50 inches of rain, residents in the east Houston community of Manchester emerged from their homes and gave thanks that their neighborhood had been spared in the floods. "Mama, yeah, I just feel blessed," said 73-year-old Maria Julia Rodriguez, standing in her driveway in late August and marveling at her luck. "God was looking out for us, I guess."

Medical workers in Houston are dealing with a secondary problem after last week's floods: Clinics that offer methadone and other opioid addiction therapies are just getting back up and running, and many people don't have access to the treatments they need.

Among the most pressing medical needs facing Houston at the moment: getting people to dialysis treatment.

At DaVita Med Center Dialysis on Tuesday afternoon, nurses tended to dozens of patients on dialysis machines while another 100 people waited their turn. Some were clearly uncomfortable, and a number said they hadn't been dialyzed in four days.

Those delays can be life-threatening.

The first problem with the airplane bathroom was its location.

It was March. Greg O'Brien and his wife, Mary Catherine, were flying back to Boston from Los Angeles, sitting in economy seats in the middle of the plane. "We're halfway, probably over Chicago," Greg remembers, "and Mary Catherine said, 'Go to the bathroom.' "

"It just sounded like my mother," Greg says. So I said 'no.' "

Mary Catherine persisted, urging her husband of 40 years to use the restroom. People started looking at them. "It was kind of funny," says Greg.

"They're not gonna want me to play 'babies in space'," says Greg O'Brien. "You know, where I pick 'em up in my hands and I swirl them around over my head like a rocket ship. I always say 'Babies! In! Spaaaaace!' "

It's October 2016, and he is musing about the latest O'Brien family news. His daughter, Colleen, is due to have a baby in November, and ever since he found out, Greg has been struggling with competing emotions.

Emotions, the classic thinking goes, are innate, basic parts of our humanity. We are born with them, and when things happen to us, our emotions wash over us.

"They happen to us, almost," says Lisa Feldman Barrett, a professor of psychology at Northeastern University and a researcher at Harvard Medical School and the Massachusetts General Hospital.

Diagnosing attention deficit hyperactivity disorder can be difficult. The symptoms of the disorder, as defined by the Diagnostic and Statistical Manual, or DSM, have changed multiple times.

Even if you know what to look for, many of the symptoms are pretty general, including things like trouble focusing and a tendency to interrupt people. Discerning the difference between people who have a problem and those who are just distracted requires real expertise.

Twenty percent of children who were in a car crash where someone died were not buckled in properly or were not wearing a seat belt at all, a study finds, as were 43 percent of children who died themselves.

And child fatality rates in deadly car crashes vary widely by state.

Inflatable beds can be cheap, which is good news for consumers who want an alternative to pricey traditional mattresses. But their uneven, soft, impermeable surfaces are dangerous for babies, and can increase the risk of sudden infant death.

The dangers may be particularly acute for low-income families, a recent essay in the American Journal of Public Health argues.

Another day, another study undercutting the myth surrounding the 18th-century Italian violin maker Antonio Stradivari.

Since the early 20th century, musicians and instrument experts have been trying to figure out what, if anything, makes the violins he made sound better.

A new study suggests that skipping meals is difficult.

Obviously, right?

The study published Monday in JAMA Internal Medicine did not set out to investigate the hardships of abstaining from food. The main question was: Is alternate-day fasting more effective for weight loss and weight maintenance compared with daily calorie restriction?

Researchers in Germany have found that getting drunk is associated with abnormal heart rhythms.

Their study was conducted in a place teeming with potential research subjects.

The Food and Drug Administration says children under 12 should not be given prescription medicines that contain codeine or another narcotic, tramadol, and that such drugs can also be dangerous to youth between 12 and 18.

For more than 40 years, Oliver O'Reilly's shoelaces have been coming untied pretty much every day. And for most of those 40 years O'Reilly didn't think too much about it.

But then, about a decade ago, his daughter Anna was learning to tie her shoes, and O'Reilly decided his shoelace problem wasn't worth passing on to another generation.

People are still dying of cancer linked to asbestos, the U.S. Centers for Disease Control says, despite decades of regulations meant to limit dangerous exposure.

Starting in 1971, the Occupational Safety and Health Administration has regulated how much asbestos workers can be exposed to, because it contains tiny fibers that can cause lung disease or cancer if they are swallowed or inhaled.

Do you pop up from your seat during meetings and finish other people's sentences? And maybe you also procrastinate, or find yourself zoning out in the middle of one-on-one conversations?

It's possible you have adult ADHD.

Six simple questions can reliably identify adults with attention-deficit/hyperactivity disorder, according to a World Health Organization advisory group working with two additional psychiatrists.

The questions are:

The first time cardiologist Sonia Tolani performed CPR outside a hospital was in 2009.

She was on the subway in New York City, headed home from work, when she saw a man slump to the ground and stop breathing.

"It was super crowded, it was like rush hour," she remembers. "I just decided we needed to do something, and dragged him out into the center of the subway train [and] I just started doing CPR."

Secretary of Veterans Affairs David Shulkin says the Department of Veterans Affairs "is on a path toward recovery."

"We have a clear mandate to do better, [and] to make sure that we're honoring our mission to serve our veterans," Shulkin told NPR's Morning Edition.

Celiac disease, the autoimmune disorder that prevents people from digesting gluten, affects about 1 percent of the population.

But there's not enough evidence to recommend screening everybody to find that 1 percent, an advisory panel said Tuesday.

The Food and Drug Administration says at least nine women have died of a rare blood cancer after receiving breast implants, and that the agency is officially acknowledging an association between the implants and the disease.

On Tuesday, the agency announced that as of Feb. 1, it had received 359 breast implant-associated reports of a rare type of non-Hodgkin's lymphoma called anaplastic large cell lymphoma, or ALCL.

Nearly five years ago, the nation's leading group of obstetricians and gynecologists issued a policy statement saying the time had come for oral contraception to be available without a prescription.

We wrote about it and everything.

Michael Botticelli served as President Obama's director of National Drug Control Policy, and pushed Congress to pass a funding measure last year making more money available for the treatment of opioid addiction.

Now he's concerned that the proposed Republican health plan will reduce access to health services for people with addiction.

The proposed American Health Care Act targets the health provider Planned Parenthood with a set of proposed limits on Medicaid payments to the organization.

On Monday, as GOP leaders tried to rally Republican lawmakers to support their health care proposal, the non-partisan Congressional Budget Office released a report showing that the plan would lead to an estimated 14 million fewer people with health insurance by next year.
