Several Media Outlets Overhype Very Early Stem Cell Research

Journalist Larry Husten, on his Cardiobrief blog, writes, “Hype Aside, Hope for Stem Cell Therapy May Be Emerging From Hibernation.

It was one of the only notes of caution we saw in our limited sampling of news stories about an analysis of an experimental stem cell intervention in 14 people – only 8 of whom were followed for a year. Husten wrote:

“Two small studies of cardiac stem cells for the treatment of heart failure have shown promise, but ABC News, CBS News and other media outlets are throwing around words like “medical breakthrough” and “heart failure cure.” ABC News correspondent Richard Besser was so enthusiastic that anchor Diane Sawyer commented that she had never seen him “so excited.” The first author of one of the studies, Roberto Bolli, said the work could represent “the biggest advance in cardiology in my lifetime.”

The reality may be somewhat more prosaic.” Read more »

Problem In Health News Stories: Therapeutic Misconception

A story in the San Diego Union-Tribune describes testing of “an experimental therapeutic filtering device being developed.”

Think about it. It hasn’t been proven therapeutic yet if it’s still experimental.

Lawyers use a term, “therapeutic misconception,” which is important for everyone to know about and think about. It refers to study participants perhaps having the misconception that the purpose of the trial is, indeed, therapeutic – when that hasn’t been established yet.

I see news stories commit this error all the time. Read more »

For Shame: Physicians Deny Care To Those Who Are Obese And Pregnant

How does one teach compassion? Either you have it or you don’t. A recent article in the Los Angeles Times made me cringe.  In South Florida, fifteen ob-gyn practices out of 105 polled said that would not take care of a pregnant woman who weighed more than 200 to 250 pounds.  The article goes on to describe two ob-gyn business partners who cited malpractice issues and fear of being sued as a reason for excluding obese women in their practice. So, what’s next? Will pregnant women be denied access to care based on bank accounts or zip codes? Where their children attend school? Whether they own a pet? Where do we draw the proverbial line?

One of my most frustrated moments in clinical practice was dealing with an imaging center who had cancelled my patient’s ultrasound procedure because they were “afraid she was going to break their table.” The patient was excited about her first pregnancy and wanted to do everything in her power to have a healthy baby. The first time I met her, she was almost apologetic about her weight. Most obese patients are. My staff had to locate an imaging center that was not only willing to accept the patient but her Medicaid insurance as well. No one should not have to endure that level of humiliation.

Whether we like it or not, Americans are obese and as physicians, we have done very little to reverse that process. I learned more about nutrition from Weight Watchers® then I did in medical school. Read more »

Diet Soda And Your Risk For Heart Attack Or Stroke

It tastes sweet. It’s pleasurably fizzy. And free of calories. What’s more, the FDA says NutraSweet (aspartame) is safe. So what’s not to like about diet soft drinks?

A bunch. The ongoing debate about the healthiness of diet soft drinks reminds me of the old adage, “If something sounds to be true, it probably is.”

Artificially-sweetened “diet” drinks get touted as healthy alternatives to sugary drinks because they contain no calories or carbohydrates. On paper it seems plausible to think they are inert, no more dangerous than water. The Coca-Cola Company sublimely strengthens this assertion by putting a big red heart on Diet Coke cans.

But diet-cola news (Los Angeles Times) presented at the International Stroke Conference 2011 suggests otherwise. This widely-publicized observational study of 2,500 older patients (average age=69) from New York showed that drinking diet soda on a daily basis increased the risk of having a heart attack or stroke by 61 percent. The abstract — not a peer-reviewed study — stated that this association persisted after controlling for other pertinent variables.

Sure, this is only a look back at 559 patients who had a vascular event. The study asserts only an association, not that diet colas cause heart attacks and strokes. That’s a big difference.

That said, however, I don’t view these results as trivial either. This trial builds on the results of prior studies of diet drinks which strongly suggest that despite their lack of calories, diet drinks don’t prevent obesity. Read more »

Still The “Incredible, Edible” Egg

Enriched chicken feed may have resulted in eggs having less cholesterol and more Vitamin D than previously measured, reports the U.S. Department of Agriculture (USDA).

A large egg today has about 185 milligrams of cholesterol, down 14 percent from 215 milligrams in 2002, according to new research from the USDA’s Agricultural Research Service, reports USA Today. Also, an egg today has 41 international units (IUs) of Vitamin D, up 64 percent from 25 IUs measured in 2002. (That’s still only about 7 percent of the 600 IUs recommended per day.)

The agency regularly does nutrient checks on popular foods, this time analyzing eggs taken from store shelves in 12 locations around the country. The American Egg Board said in a press release that hen feed is made up mostly of corn, soybean meal, vitamins and minerals. Nutrition researchers at Iowa State University are also looking into reasons why cholesterol in eggs is decreasing.

The government’s “Dietary Guidelines for Americans” recommend that most people eat less than 300 milligrams of total dietary cholesterol a day, and people at a high risk of cardiovascular disease should eat less than 200 milligrams a day. The average American man consumes about 337 milligrams of cholesterol a day and the average woman consumes 217 milligrams, reports the Los Angeles Times.

One egg a day fits within the average, healthy American’s diet, reports WebMD, citing research funded by the Centers for Disease Control and Prevention and by the American Egg Board — owners of the slogan “the incredible, edible egg.”

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
