Maybe You Should Skip That Annual Physical

Apr 6, 2015

It's a warm afternoon in Miami, and 35-year-old Emanuel Vega has come to Baptist Health Primary Care for a physical exam. Dr. Mark Caruso shakes his hand with a welcoming smile.

Christina Costanzo was 32 when she had her first heart attack. It all started on a Friday.

"I had chest pain. I had pain in my jaw, pain going down my left arm. I had some shortness of breath," Costanzo recalls.

But Costanzo who is a nurse practitioner in New Haven, Conn., didn't realize right away that these were symptoms of a heart attack. She figured this was just her body reacting to stress, and she didn't want to overreact.

Marcie Sillman talks to Luke Timmerman, of the Timmerman Report, about the Fred Hutchinson's Cancer Research Center's efforts to find new ways to bring in revenue for research. 

The Food and Drug Administration is weighing whether to allow a tobacco company to do something it's never done before — claim that one of its products is less risky than cigarettes.

The company, Swedish Match of Stockholm, has applied to the FDA to designate its General brand of snus (rhymes with "loose") as safer than other versions of tobacco.

Marcie Sillman talks with Washington State University neuroscientist Barbara Sorg about her new research into addiction and memory.

The human armpit has a lot to offer bacteria. It's moist, it's warm, and it's usually dark.

But when the bacteria show up, they can make a stink. That's because when some kinds of bacteria encounter sweat they produce smelly compounds, transforming the armpit from a neutral oasis to the mothership of body odor. And one group of bacteria is to blame for the stink, researchers say.

"An epidemic is one of the few catastrophes that could set the world back drastically in the next few decades," Bill Gates warns in an essay he wrote for the March 18 edition of The New England Journal of Medicine.

In the article, titled "The Next Epidemic — Lessons From Ebola," he says the Ebola epidemic is a "wake-up call."

Maybe you've seen them in the gym, or even squeezed into them yourself: super-tight T-shirts, leggings, knee and calf sleeves, even tube tops. More and more athletes are wearing compression garments, hoping they will improve their performance and recovery.

But do they work? This is a question Abigail Stickford, a postdoctoral researcher at UT Southwestern Medical Center in Dallas, wanted to answer.

Few people come into contact with farm chemicals the way agricultural workers do. That's why a new health report on a commonly used herbicide is raising special concerns about farmworkers and cancer.

Shane Avery practices family medicine in Scott County, Ind. In December, a patient came to his office who was pregnant, and an injection drug user.

After running some routine tests, Avery found out that she was positive for HIV. She was the second case he had seen in just a few weeks.

"Right then, I kind of realized, 'Wow, are we on the tip of something?' " Avery says. "But you just put it away. ... It's statistically an oddity when you're just one little doctor, you know?"

MaryAnn Anselmo feared for the worst when she was diagnosed with a brain tumor called a glioblastoma in late 2013.

"You start doing research on that type of tumor, and you're saying, 'Oh my God, you're history.' It's like a death sentence," says, Anselmo, now 59.

Only for her it wasn't.

Anselmo's successful treatment shows how precision medicine — tailoring therapy to each patient's genetic needs — is beginning to transform cancer care.

As you’ve probably heard, a well-respected group of World Health Organization scientists said glyphosate, the active ingredient in Monsanto’s wildly popular Roundup herbicide and its generic cousins, is probably capable of causing cancer in humans.

Here are five things you should know:

1. What the report said: Roundup could cause cancer in humans.

More than 10 million Americans have trouble distinguishing red from green or blue from yellow, and there's no treatment for colorblindness.

A biotech company and two scientists hope to change that.

The videos are almost unbelievable. Ketchup slides out of the jar and you don't even have to give it a thump. Glue slips out of the bottle without a molecule left inside. And what about getting that last smidgen of toothpaste from a used tube? No problem.

Welcome to the world of LiquiGlide.

An international committee of cancer experts shocked the agribusiness world a few days ago when it announced that two widely used pesticides are "probably carcinogenic to humans." The well-respected International Agency for Research on Cancer published a brief explanation of its conclusions in The Lancet and plans to issue a book-length version later this year.
