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.

As Texas looks to reduce its maternal mortality rate, there is one aspect of the crisis that is going to be harder to solve: Black women are more likely to die while pregnant or after giving birth than women from other racial or ethnic groups.

Texas officials have been slow to respond to the state's maternal mortality crisis.

In the last year, lawmakers have passed legislation aimed at improving death certificate data, and they extended the life of a task force investigating why mothers are dying. But advocates are pushing state health officials to do more.

This flu season is making regular headlines, especially in North Texas, where more than 100 people have died. It doesn't compare to the flu crisis the world endured a century ago, but we can still learn from it. 

Part 1 of a three-part series.

An alarming number of women die while pregnant or shortly after giving birth in Texas. According to national researchers who say the U.S. as a whole has a serious problem, Texas is an “outlier” when it comes to its high rate of maternal deaths.

A new study has found more stroke victims may be saved from disability or death if doctors can remove blood clots that block circulation to the brain. It also found doctors may have more time than originally thought to perform the treatment.

A team at the University of Texas at Dallas is developing a new method to treat pain by disrupting how the body processes it. 

Zachary Campbell researches pain on the molecular level at UT Dallas. His team's work describes a new method of reducing pain with RNA-based medicine. RNA stands for ribonucleic acid, which carries out genetic information from DNA to proteins.

Some things will decline as we get older — that’s inevitable.

Physical strength, balance and endurance erode, our eyesight worsens, women quickly lose bone mass after menopause, and male testosterone levels drop.

When it's cold outside, alcohol might feel like a way to fend off the winter chill, but health care experts warn alcohol and cold weather can be a bad combination if you’re not careful.

Addiction to opioids often begins in the doctor’s office. These drugs are typically the only option to manage pain after an operation or in patients with serious injuries. They’re also frequently prescribed to patients with chronic pain, and it’s these patients who are most at risk for opioid addiction.

Autism affects about one in 68 children, and the condition poses social challenges, including difficulty processing social interactions, such as facial expressions and physical gestures.

New research out of UT Southwestern Medical Center in Dallas shows those social behaviors could be restored through a process called "neuromodulation," or brain stimulation.

For many, a list of New Year’s resolutions tends to include losing weight. Before considering diets, gyms, expensive equipment and tech gadgets, a local dietitian offers some sensible ideas to help with weight reduction.

The flu doesn't just make you feel lousy. A study published Wednesday finds it can increase your risk of having a heart attack, too.

"We found that you're six times more likely to have a heart attack during the week after being diagnosed with influenza, compared to the year before or after the infection," says study author Dr. Jeff Kwong, an epidemiologist and family physician with the Institute for Clinical Evaluative Sciences and Public Health Ontario in Canada.

Flu season has been especially severe this year in North Texas. Earlier this month, the Walgreens flu index ranked Dallas-Fort Worth the seventh most active metropolitan area in the country, prompting area hospitals to push flu prevention more than usual.

But those reminders can often miss the most vulnerable in the community – so a roving flu clinic in Fort Worth is closing the gap.

When parts of the federal government ground to halt this past weekend, Linda Nablo, who oversees the Children's Health Insurance Program in Virginia, had two letters drafted and ready to go out to the families of 68,000 children insured through the program, depending on what happened.

One said the federal government had failed to extend CHIP after funding expired in September and the stopgap funding had run out. The program would be shutting down and families would lose their insurance.

A study from cardiologists at UT Southwestern Medical Center and Texas Health Resources has found that exercise can reverse damage to the heart in a sedentary adult – if he or she does enough exercise in time. 

While Texas' infant mortality rate is lower than the national average, a new study shows wide differences in rates across different areas of the state and among different racial groups.

Almost the same number of Texans who signed up for health insurance through the Affordable Care Act (ACA) during the last enrollment period signed up this time, according to the federal government. The figure took experts by surprise because there were federal cuts in funding for outreach and assistance.

For years, Ramey Market in Fort Worth’s historic Stop Six neighborhood has been an utterly unremarkable convenience store selling the typical assortment of sundry items, snacks and sodas. It was just the closest place to buy cigarettes or lottery tickets or beer.

Texas is first in flu according to Walgreens, and both the Dallas County and Tarrant County health departments are tracking a steep uptick in the number of positive tests.

According to the Centers for Disease Control and Prevention, this year's vaccine is thought to be about 32 percent effective, just like last year's.

In September of 1982, a 12-year-old girl and six adults in and around Chicago died suddenly and mysteriously. Hundreds of investigators looked into the cases and discovered that all the victims had taken Tylenol laced with cyanide.

Texas is over-reporting some of its maternal mortality data, a national study released today found.

The study, from the University of Maryland Population Research Center and published in the journal Birth, is a follow-up to a study released in August 2016 that found the maternal mortality rate in Texas had doubled in a two-year period.

The value of the digital cryptocurrency bitcoin has been all over the map recently, reaching a high of about $20,000 per coin late last year to nearly $14,000 this week. That's a big leap for something that was worth just a dollar in 2011. 

But what exactly is bitcoin?
