We’re delighted to see that USA Today, Reuters, and WebMD were among the news organizations that included what an editorial writer said about an observational study linking ibuprofen use with fewer cases of Parkinson’s disease. All three news organizations used some version of what editorial writer Dr. James Bower of the Mayo Clinic wrote or said:
“Whenever in epidemiology you find an association, that does not mean causation.”
“An association does not prove causation.”
“There could be other explanations for the ibuprofen-Parkinson’s connection.”
Kudos to those news organizations. And some praise goes to the journal Neurology for publishing Dr. Bower’s editorial to accompany the study. His piece is entitled, “Is the answer for Parkinson disease already in the medicine cabinet? Unfortunately not.”
And unfortunately not all news organizations got that message. Because many don’t read the journals, so they certainly never get to the editorials. Instead, they rewrite quick hits off a wire service story. As a result, we end up with some of the following:
A FoxNews.com story was particularly deaf to Bower’s caveat, stating: “That bottle of ibuprofen in your medicine cabinet is more powerful than you may think.”
A CBSNews.com story never addressed the observational study limitation, instead whimsically writing: “Pop a pill to prevent Parkinson’s disease? A new study says it’s possible, and the pill in question isn’t some experimental marvel that’s still years away from drugstore shelves. It’s plain old ibuprofen.” Read more »

Among fans who attend live sporting events, drinking alcohol is nearly as commonplace as root-root-rooting for the home team. And while virtually no one has a problem with a fan who pushes back a beer or two during the game, flat-out drunk fans can ruin the experience for those sitting nearby. Worse yet, these people frequently get behind the wheel of a car after the game is over.
Recently, Darin Erickson and colleagues at the University of Minnesota decided to find out just how many fans go overboard at games, and their findings are worrisome, indeed. Using standard blood alcohol testing on 362 adult volunteers who were leaving 13 professional baseball and three professional football games, the scientists found that 40 percent had measurable levels of alcohol in their blood and a stunning eight percent were legally drunk (as defined by a blood alcohol level of .08 or greater). The highest alcohol level recorded by the scientists was .22.
Erickson’s group also observed that Monday Night Football attendees were more likely than other fans to have been drinking. In addition, fans who were 35 years old or younger were eight times more likely to leave the game drunk, and those who attended tailgating parties before the game were 14 times more likely to leave the game drunk.
The latter finding is consistent with a study from the University of Toledo, in which scientists gave breathalyzer tests to tailgaters at a college football game. The scientists found that an astounding 90 percent of the participants consumed alcohol during tailgate festivities, and among them, the average blood alcohol concentration was 0.06, well on the way to being legally drunk.
Maybe these people should save the money they spent on tickets and go to a bar. Erickson’s study was published in Alcoholism: Clinical & Experimental Research.

It’s hard to believe that turbulence could be a good thing for the heart. Consider how the word turbulent is defined: “Characterized by conflict, disorder, or confusion; not controlled or calm.” Those traits don’t sound very heart-healthy. But when it comes to heart rhythm, it turns out that a turbulent response — to a premature beat — is better than a blunted one. The more turbulent the better.
No, you haven’t missed anything, and turbulence isn’t another of my typos. Until [recently], heart rate turbulence was an obscure phenomenon buried in the bowels of heart rhythm journals.
What Is Heart Rate Turbulence (HRT)?
When you listen to the heart of a young physically-fit patient, you are struck not just by the slowness of the heartbeat, but also by the variability of the rhythm. It isn’t perfectly regular, nor is it chaotic like atrial fibrillation (AF). Doctors describe this — in typical medical speak — as regularly irregular: The heart rate increases as the patient inhales and slows as he or she exhales. This variability occurs as a result of the heart’s responsiveness to its environment. The more robustly and quickly the heart responds, the healthier it is.
HRT seeks to measure how quickly and vigorously the heart rate reacts in response to a single premature beat from the ventricle — a premature ventricular contraction (PVC). Normally after a PVC, the heart rate speeds for a few beats, and then slows back to baseline over the next 10 beats. The healthy heart responds with a more intense rise in heart rate and a quicker return to baseline. Using simple measurements of heart rate from a standard 24-hour electrocardiogram (ECG) monitor, a propriety software program averages many of these responses and comes up with a measurement of turbulence onset and turbulence slope.

There are few medical conditions that people fear more than a stroke. We know that blood pressure control and lowering cholesterol levels reduces stroke risk. Now, thanks to a huge analysis from Italy published in the Journal of the American College of Cardiology, we know that higher dietary consumption of potassium is associated with lower rates of stroke and could also reduce the risk of coronary heart disease and total cardiovascular disease, too. What is even more remarkable is that the results apply to all parts of society and not just to specific “at-risk” subgroups.
Most doctors aren’t even aware of how important it is to eat potassium-rich foods. And what are these foods that have potassium? Surprise: It’s fruits and vegetables like bananas, tomatoes, oranges, apricots, most legumes, spinach, winter squash, avocado, kiwi, and cantaloupe. Actually, almost all fruits and veggies have moderate to high potassium content.
The researchers looked a number of well-done studies that included 247, 510 participants over age 30 and found that those patients with the higher potassium intake reduced their stroke risk by 21 percent. The Italian doctors say the protective effect of potassium against stroke is in part due to its blood pressure lowering effects and also due to other properties of the potassium mineral, such as the inhibition of free radical formation.
I’ve written before about the DASH diet, which also found that reduction of sodium and addition of fruits and vegetables to the diet is an effective way to control blood pressure. The DASH diet is high in potassium.
Think about it: Did you have five servings of fruits and vegetables today? Numerous studies have shown their life-prolonging benefits. This new study just adds to what we already know. I challenge all readers to keep a diet count and make sure you are eating five fruit and vegetable servings a day — every day — to help reduce your risk of stroke, cancer, and heart attack.

[Recently] in The New York Times, David Tuller [wrote] about a study published in The Lancet that shows that psychotherapy is an effective treatment for chronic fatigue syndrome. In his article “Psychotherapy Eases Chronic Fatigue, Study Shows,” Tuller writes:
The new study, conducted at clinics in Britain and financed by that country’s government, is expected to lend ammunition to those who think the disease is primarily psychological or related to stress.
The authors note that the goal of cognitive behavioral therapy, the type of psychotherapy tested in the study, is to change the psychological factors “assumed to be responsible for perpetuation of the participant’s symptoms and disability.”
In the long-awaited study, patients who were randomly assigned to receive cognitive behavioral therapy or exercise therapy, in combination with specialized medical care, reported reduced fatigue levels and greater improvement in physical functioning than those receiving the medical care alone — or getting the medical care along with training in how to recognize the onset of fatigue and to adjust their activities accordingly.
Interesting. Generally I like to stay away from the “it’s all in your head” debates. I’ll let the commenters do the talking here.
