Our brains can easily fool us. No experienced doctor would deny the power of the placebo effect. Today I want to discuss the nocebo effect, which occurs when negative expectations of something causes it to have a more negative effect than it otherwise would. Drugs can exert a strong nocebo effect. If your brain thinks […]
Statins, Like All Medicines, Are Neither Good Nor Bad
We have to talk about drugs. No, not illicit drugs, but medications used by doctors and patients. Plaintiff attorneys run ads on TV that fool people into thinking certain meds are bad. The current one I deal with is the clot-blocking drug rivaroxaban (Xarelto.) Before that, it was dabigatran (Pradaxa). If, or when, the makers […]
On the intolerance of ideas, and liberty …
I like thinking and learning. Birthdays surely make one slower on the bike, but birthdays, it seems, do not have the same drag on the brain. For me, birthdays have increased my appreciation of liberty. In the Constitution of Liberty, Hayek defines it as the absence of coercion. Such is a beautiful definition. Don’t coerce […]
Trust and Medical Science
Concerned citizens will march this weekend to defend science. Standing up for science is a worthy cause. Look at what medical science has accomplished in recent times: serious diseases, HIV, heart attack, many forms of cancer, have been tamed by the advance of science. We need more not less science. It’s nuts to cut funding […]
Four Crucial Questions To Ask Your Doctor
I am seeing an increasing number of patients who did not know they had a choice about taking a medicine or having a procedure. Why did you have that heart cath? A: My doctor said I should. Why are you on that medicine? A: My doctor prescribed it. It’s time we re-review the basic four […]
Vitamin C and Sepsis: Resist the Urge to be Duped.
My Facebook feed has been buzzing with news of a breakthrough in the treatment of sepsis–a deadly condition caused by bacterial infection. Do not be fooled. Please. Resist the urge to be duped. A recent study published in the prestigious journal Chest concluded that a combination of high-dose vitamin C, anti-inflammatory corticosteroids and thiamine given […]
Politics and Understanding the Human Condition
I recently received this message: This is not the first time I’ve been scolded for straying from medical topics. Last October, during the Lown Institute’s RightCare Action Week, I wrote about our ailing healthcare system. This prompted a different reader to send a similar message: Stick with topics about atrial fibrillation–went the gist of that […]
Is AF ablation a big placebo?
Turkish authors boldly raised this question in a recent editorial. They likened AF ablation to renal denervation, a procedure in which RF ablation in the kidneys was felt to reduce BP. Many studies showed kidney ablation markedly lowered BP. Then a trial was done with a sham control (people got part of the procedure but […]
Another thing to fear in healthcare: Getting an Xray
I head to Chicago this weekend for the 4th Annual Lown Institute Conference. The Lown Institute seeks to catalyze grassroots movements for transforming healthcare systems and improving the health of communities. For those of you who want to be on the right side of the street of history, Dr. Bernard Lown, a cardiologist, activist, and […]
More on the gambling decision to take statins
In my last post, I wrote my initial thoughts of an important new study on how the decision to take a medication or have a screening test in the name of prevention is similar to playing the lottery. I promised to think and write about the study more carefully. My latest thoughts are now published […]
Science Needs Data Sharing Like Sports Needs Doping Controls
I’ve got a good story for you. One that goes back to the early days of this blog, a time when I wrote about cycling. It turns out that the biggest medical news thus far in 2016 has a connection, albeit slight, to the recent doping news out of Belgium. You’ve heard the news from […]
