Vital Signs

In Vital Signs, Sam Baker taps into the expertise of local health care leaders to provide insight into your everyday health and well-being.

Breakthroughs

In Breakthroughs, KERA reporters delve into the latest health-related technologies developed in North Texas and across the state. From the Zika virus to fried chicken, no scientific topic is off limits. 

Learn more in-depth multimedia projects: Surviving Ebola, a look at how Ebola made its way to Dallas and the lessons local hospitals and governments learned; Growing Up After Cancer, the journey of one North Texas boy with cancer; and The Broken Hip, an in-depth look at how a fall can change everything.

An umbilical cord after birth yields about three to five ounces of cell-rich cord blood. That's not a lot, but enough of it can help treat more than 80 or so diseases. A North Texas oncologist says education's key to boosting limited supply.

Across the country, new babies are sleeping in cardboard boxes. It might sound strange, but the boxes are part of a larger initiative to lower the infant mortality rate. So far, more than a million "Baby Boxes" have been distributed across the world.

Another potentially dangerous trend: the "eraser challenge." That's where you vigorously rub an eraser on your skin while reciting a certain phrase or the alphabet. The results can be disfiguring or worse.

Nine in 10 Texans think it's harder to talk about a mental health condition than a physical health issue. The one place where it’s easier to talk about mental rather than physical health seems to be in the Texas Legislature, where a handful of bills are speeding through the House with near unanimous support. Among them is a bill to help enforce coverage of mental health benefits.

It hasn’t been scientifically proven as beneficial, but that hasn’t stopped many from trying for the goal of 10,000 steps a day, which is touted as a way to stay in shape. However, a new study finds 15,000 steps might be better.

Concussions are one of the most complex injuries in sports medicine today. In the past few years, there’s been an explosion of research focusing on how often concussions take place, how to measure them and how to prevent them.

A national study a few years back revealed something shocking about black men in medical school: There were fewer in 2014 than in 1978. Med school recruiters are trying to step up their game, and one Dallas doctor has a tool that could help.

Each year, more than 35,000 babies are born with congenital heart defects. Chances for survival were slim not so long ago. But today, more than a million adults live with congenital heart defects. 

New data from the U.S. Census Bureau present the most detailed picture yet of the dramatic rise in the number of people covered by health insurance since the Affordable Care Act went into effect.

County-level data going back to 2010, when the law was signed, show a patchwork of people living without health insurance that ticked down slowly for the first three years under the ACA. But once the online insurance exchanges opened at the end of 2013 and Medicaid expanded, the population living without coverage dropped noticeably.

For a parent, battling cancer is tough enough. Having to explain it to your kids can be a whole other challenge. That's why Baylor Scott & White Health has created a program that helps terminally ill parents talk to their young children about disease, treatment and death. A Dallas mother turned to Baylor specialists for help telling her son she had breast cancer.

The term "cardiomyopathy" refers to diseases of the heart muscle that make it difficult over time for the heart to pump blood throughout the body. As many as one in 500 people may have the condition. One form of it – dilated cardiomyopathy — contributed to the death of singer George Michael.

Fish oil is among the most widely used supplements in the U.S. An estimated 20 percent of Americans consume them, but some nutritionists recommend sticking with the real thing – an oily fish like salmon or tuna.

Tens of millions of Americans use inhalers each day. Many of them aren’t doing it right. That’s what new research from Baylor College of Medicine shows. Pulmonologists identified critical errors that are causing many inhaler users to get only about half as much medicine as they should from each puff.

Tonsils serve as sort of a filter in your body. Chances are many of you have had them removed, but two recent studies differ on when and if that’s necessary.

Robots aren’t just in our living rooms vacuuming rugs or in warehouses moving boxes. They’re everywhere: connecting pipes on offshore oil rigs, harvesting marijuana in Colorado and replacing batteries outside the International Space Station. They're even helping rescue refugees who are trying to cross the Mediterranean.

UT Southwestern Medical Center and the University of Miami are conducting a clinical trial of over-the counter meds – in this case, for people with bipolar disorder who have a drinking problem.

Over the past month, Baylor Scott & White Health has been distributing free diabetic shoes to its uninsured, low-income patients to combat and prevent what doctors see as a diabetes crisis in North Texas. The shoe distribution is just one part of a Baylor program that takes its own medical surplus and gives them to the needy at home and abroad.

An estimated 20 million Americans have some form of thyroid disease, which is very treatable, according to the American Thyroid Association. But more than half the people with thyroid disease don’t know they have it.

It's 2017, but medical records are still mostly stuck in the dark ages. Most hospitals use electronic health records, but if you want your primary care doctor to share information with your allergist or surgeon, it’s a pain.

A cotton nightgown for your child seems like a pretty simple thing to track down. But it wasn't for John Rodakis, a dad living in Dallas. He’d heard about dangerous chemicals once common in kids pajamas, and out of precaution, he wanted a nightgown that was made from all natural materials. He’s not the only one. There’s a whole underground market for them.

Effective screening and prevention have limited deaths from cervical cancer to about 4,000 each year. But a recent study of a dozen states over 10 years found experts may have underestimated the risk of dying from the disease.

We all need protein — it's an essential nutrient for the body. But consuming too much protein, in regular food or supplements, may have consequences.

Most adults support routine childhood vaccinations for children. That’s the conclusion of a new, nationwide Pew Research Center survey. Still, in Texas, there’s a growing group of parents who oppose mandatory childhood vaccinations.

At one point, a heart surgical procedure required opening your chest. Technology’s now made it possible in some cases to avoid open heart surgery in favor of minimally invasive procedures that are actually better for some patients.

A lot of us think rushing from task to task and packing our schedules is a necessary evil. It turns out being busy might be good for your brain. That’s the conclusion of a new study led by North Texas researchers in Frontiers in Aging Neuroscience.

Most of us experience stress at some point in our lives, personally or professionally. Here's a look at what actually causes that reaction in the body and some steps to relieve stress.

Spending time in space changes people: not just their outlook on life, but also their eyesight in general. For years, a North Texas doctor has been trying to find out what is causing this vision change among astronauts. His latest research provides some clues — and connects astronauts on the International Space Station, cancer patients on a roller coaster plane flight and high-tech sleeping sacks.
