David & Goliath: A Dramatic Role Reversal Spurred On By The Media

The Internet is teeming with false health claims and a long line of celebrities willing to throw their media weight behind every new flavor of snake oil. The irony is that alternative medicine proponents see themselves as a persecuted minority – the victims of some nebulous health industry conspiracy. But in reality, they have ingratiated themselves with the media to such an extent that they may in fact have the upper hand.

Pseudoscience has become Goliath, and physicians have never faced a more pernicious foe. With patients’ lives hanging in the balance, some of us are waging the war for hearts and minds with gumption, zeal, and a little help from a brave minority of media who have finally woken up and realized that alternative medicine is not as soft and cuddly as they once thought.

Take for example those who wrongly believe that vaccines cause autism. Many of them subject their children to unproven and harmful therapies, diets, and regimens – some of which are tantamount to child abuse. Consider the cases described most recently by David Gorski here. One child underwent repeated IV chelation therapy for years followed by the invasive injection of “stem cells” into her cerebrospinal fluid. (more…)

Monkey business in autism research, part II

Over the last couple of months, I’ve noticed something about the anti-vaccine movement. Specifically, I’ve noticed that the mavens of pseudoscience that make up the movement seem to have turned their sights with a vengeance on the Hepatitis B vaccine. The reason for this new tactic, I believe, is fairly obvious. The fact that the Hep B vaccine is administered shortly after birth seems somehow to enrage the anti-vaccine movement more than just about any other vaccine. Moreover, given that, aside from maternal-child transmission when the mother is infected, hepatitis B is usually only contracted through either bloodborne contact (the sharing of needles, the administration of contaminated blood) or sexual activity, it’s very easy for anti-vaccinationists to make a superficially plausible-sounding argument that it’s not a necessary vaccine, even though there are reasonable rationales for giving it to infants. The image of sticking a needle into a newborn infant trumps that, though, at least for the anti-vaccine movement. Another possibility, suggested by Steve Novella just yesterday, is that, with the collapse under a overwhelmingly huge pile of evidence of the idea that the mercury-containing preservative thimerosal that used to be used in childhood vaccines until 2001, caused an “epidemic” of autism and the failure of the “too many too soon” slogan to convince anyone who is not already an anti-vaccinationist, the movement needed a new bogeyman to blame for autism. The hepatitis B vaccine, which was added to the pediatric vaccination schedule in the 1990s, around the right time to confuse correlation with causation when it comes to the increase in autism diagnoses (just like thimerosal) was a perfect next target, given that it’s administered shortly after birth.

Indeed, just the other day, the anti-vaccine crank groups the National Vaccine Information Center (NVIC), Talk About Curing Autism (TACA), and the anti-vaccine crank blog Age of Autism posted a call for the elimination of hepatitis B vaccination for newborns:

Washington, DC – National Vaccine Information Center and Talk About Curing Autism are calling on President Obama to order the immediate suspension of the Centers for Disease Control and Prevention recommendation of the birth dose of the Hepatitis B vaccine after two recent studies linking the Hepatitis B vaccine to functional brain damage in U.S. male newborns and infant primates.  In a related development today, the United States Department of Health and Human Services, including the Health Resources and Services Administration and Centers for Disease Control and Prevention,  announced that 1 in every 91 children are now diagnosed with an autism spectrum disorder as reported in the November 2009 issue of Pediatrics. Previous data released by the CDC indicated a prevalence of 1 in every 150 children affected by the disorder.

Note how AoA not-so-subtly interposed the latest information about autism prevalence with its call to eliminate the birth dose of the hepatitis B vaccine. Very clever. By doing so, it linked the two in readers’ minds, as if one had something to do with the other. There’s no good scientific evidence that the hepatitis B vaccine has anything to do with the “autism epidemic.” Meanwhile, David Kirby is up to his usual nonsense, and the resident anti-vaccine propagandist at CBS News, Sharyl Attkisson, who has been known to feed Age of Autism information on at least one occasion in the past, served up this credulous, noncritical interview with Andrew Wakefield:

The quantity of misinformation in that single six minute video is far beyond the scope of this article. Were I to start dissecting it, I would not have time to do what the purpose of this article was intended to do: To deal with the study Wakefield is hawking. That’s why I leave the dissection of this pièce de résistance of disingenuousness and misinformation as an exercise for SBM readers–after reading the rest of this post, of course. Trust me, it will help you.

At the heart of this latest propaganda onslaught by the anti-vaccine movement are two studies, one a restrospective study in humans and the other a study in monkeys, both of which the anti-vaccine movement is promoting as slam dunk evidence that the hepatitis B vaccine is causing all sorts of horrific problems. Taking both of them on in one post is too much, even for my logorrheic tendencies. So I’ll deal first with Wakefield’s monkey study and then, either later this week or sometime next week, hopefully discuss the human study.

“Obesity Linked to Stupidity”- an Example of Stupid Reporting

A news story on Science a Gogo reports that obesity is linked to stupidity, according to a new study based on brain scans. Apparently the reporter can’t read. That’s not at all what the study showed.

What the Study Really Said

The study was entitled “Brain structure and obesity.”It was published in Human Brain Mapping. There were 10 authors listed, with the two interviewed for the news report being the lead author (CA Raji) and the last listed author (PM Thompson). The study evaluated MRI scans of 94 elderly subjects who were cognitively normal and remained cognitively normal for at least 5 years after their scan. It found that obese people had 8 percent less brain tissue than people with normal weight, while overweight people had 4 percent less tissue. The deficits were in areas of the brain that have been associated with Alzheimer’s disease. The story reports that this put the subjects at high risk for Alzheimer’s disease. But the subjects remained cognitively normal for at least 5 years after the scan. They were not rendered stupid. They did not develop Alzheimer’s. They remained cognitively normal. You might also interpret the study as showing that obese patients with those findings on brain scan could be predicted not to develop Alzheimer’s or develop any other cognitive deficits for at least five years.

The Huffington Post is at it again

As many of our readers know, there are plenty of websites devoted entirely to fake medicine. Sites such as whale.to and NatrualNews are repositories of paranoid, unscientific thinking and promotion of dangerous health practices. Thankfully, they are rather fringe (but not fringe enough). More mainstream outlets print some pretty bad stuff, but it’s usually just lazy reporting and not a concerted, organized effort to promote implausible medical claims. As many of us have written, both hear and at our other blogs, the Huffington Post is the exception. It actively and in an organized way promotes dangerous, implausible pseudo-medicine. This starts at the top with Arianna, and is actively encouraged by medical and health editors like Patricia Fitzgerald and Dean Ornish.  In the spring, our complaints were picked up briefly by the larger blogosphere and for a while, HuffPo appeared to have toned it down.  Some of that may have been due to our critique of their flu coverage, much of which was mere infomercials for patent medicine.

As the old joke goes, “Break’s over—back on your knees.”  HuffPo has jumped back into the quakery pond with full abandon.  Venues like HuffPo are one of the reasons a site like this one are necessary.  So let’s take a look at the latest abominations from “the other side”.

The price of anti-vaccine fanaticism: Case histories

One of the major themes of SBM has been to combat one flavor of anti-SBM movement that believes, despite all the evidence otherwise, that vaccines cause autism and that autism can be reversed with all sorts of “biomedical” quackery. Many (but by no means all) of these so-called “biomedical” treatments are based on the false view that vaccines somehow caused autism. I and my fellow SBM bloggers have expended huge quantities of verbiage refuting the pseudoscience, misinformation, and outright lies regularly spread by various anti-vaccine groups and two celebrities in particular, namely Jenny McCarthy and her boyfriend Jim Carrey. Most of the time, we discuss these issues in terms of the harm to public health that is done by falling vaccination rates due to the fear engendered by the message of the anti-vaccine movement and the threat of the return of vaccine-preventable diseases that once wreaked havoc among children.

There is another price, however. There is a price that is paid by autistic children themselves and their parents. It is a price paid in money and lost time. It is a price paid in being subjected to treatments that are highly implausible from a scientific standpoint and for which there is no good scientific evidence. It is a price that can result in bankruptcy, suffering, and, yes, even death.

It is a price, I think, that is best demonstrated through a few case studies. This is a situation when anecdotes have their use.

Bill Maher endorses cancer quackery

Over the last five years or so, I’ve often asked, “Is Bill Maher really that ignorant?” I’ve come to the conclusion that he is, and a couple of weeks ago laid out the evidence why right here on this very blog. (Lately Maher has been issuing Tweets that call people who get flu shots “idiots.”) Indeed, I even included in the post perhaps the most hilariously spot-on riposte to Maher’s crankery. This occurred when Maher proclaimed that he never gets the flu and wouldn’t get the flu on an airplane, which his guest Bob Costas to exclaim in exasperation, “Oh, come on, Superman!”

Bob Costas won my respect that day. My favorite part was when Maher looked at his guests, who were shifting in their seats, all embarrassed and unsure of what to say, and observed, “You all look at me as though I’m crazy.”

Why, yes, Bill, we do. Let’s put it this way. When Age of Autism likes you, you have a serious problem when it comes to being credible about medical science.

In that same post, I complained about Maher’s being awarded the Richard Dawkins Award by the Atheist Alliance International (AAI). I liken giving Bill Maher an award that lists “advocates increased scientific knowledge” anywhere in its criteria, not to mention being named after Richard Dawkins, to giving Jenny McCarthy an award for public health, given that, at least when it comes to medicine, Maher is anti-science to the core. Along the way, I’ve ruffled the feathers of some of both Dawkins’ and Maher’s fans.

I regret nothing.

Not only do I regret nothing, but on September 18, a mere two weeks before the AAI Convention, Maher provided me with more ammunition. In fact, this is probably the most blatant bit of crankery I’ve seen from Maher in a long time. Watch and learn. The “alternative medicine” nuttery begins at around the 0:50 mark:

Laetrile? Really? Laetrile?? How 1970s cancer quackery!

HIV/AIDS denialists do it too!

Remember my post from Monday about fake scientific conferences organized by the anti-vaccine movement that are designed to paint a picture of legitimate science being done, so much so that they even fool some academics into speaking there? (I realize that the server issues we had from Monday through Wednesday that rendered the site completely FUBAR may have prevented some of you from reading it.)

Well, it turns out that HIV/AIDS denialists do it too!

Why am I not surprised?

Is Francis Collins Bringing Sexy Back To Science?

rockstarsofscience1

Rudy Tanzi, Joe Perry, Francis Collins

I know. I was just as surprised as you are. Dr. Francis Collins, former director of the Human Genome Project, author of The Language Of God, and new director of the National Institutes of Health performed live in front of a group of Washington locals at the Capitol building today. He actually jammed with Aerosmith’s Joe Perry in an “unplugged” performance of Bob Dylan’s, “The Times They Are A Changin’.” This is not the kind of thing one expects in the hallowed halls of the Capitol building. But maybe it’s time to expect the unexpected?

I’ve spent some time on this blog wondering about the difference between being “right” and being “influential” – and how to combat the Jenny McCarthyism that is misleading Americans about their health. I’ve argued that we need to find a way to rekindle the public’s interest in good science, and learn to speak to folks in a way that is captivating and respectful. I guess that some of our peers are engaged in a rebranding of science.

Crank “scientific” conferences: A parody of science-based medicine that can deceive even reputable scientists and institutions

If there’s one thing that purveyors of pseudoscientific medical modalities crave, probably above all else, it’s legitimacy. They want to be taken seriously as Real Scientists. Of course, my usual reaction to this desire is to point out that anyone can be take seriously as a real scientist if he is able to do science and that science actually shows that there is something to his claims. In other words, do his hypotheses make testable predictions, and does testing these predictions fail to falsify his hypotheses? That’s what it takes, but advocates of so-called “complementary and alternative medicine” (CAM) or “integrative medicine” (IM, or, as I like to refer to it: “integrating” quackery with scientific medicine) want their woo to be considered science without actually doing the hard work of science.

There are several strategies that pseudoscientists use to give their beliefs the appearance of science, a patina of “science-y” camouflage, if you will. One, of course, is the cooptation and corruption of the language of science, which has been a frequent topic on this blog, particularly in posts written by Drs. Atwood and Sampson. Another is to produce journals that appear to be science, but are anything but. I’ve discussed one example, the Journal of American Physicians and Surgeons and Medical Acupuncture, but others include Homeopathy, the Journal of Alternative and Complementary Medicine, and Medical Hypotheses, which recently was forced to retract a horrible paper by arch-HIV/AIDS denialist Peter Duesberg. What’s worse is that some of these journals are even published by what are considered major publishers, such as Mary Ann Liebert, Inc., and Elsevier.

There is, however, a third strategy. How do scientists communicate their findings to other scientists, as well as meeting and mingling with other scientists? Why, they hold scientific meetings, of course! These meetings can be small or even as large as the American Association for Cancer Research meeting, which is attended by around 15,000 cancer researchers each year. So, too, do cranks hold meetings. These meetings often have all the trappings of scientific meetings, with plenary sessions, smaller parallel sessions, poster sesssions, and an exhibition hall, complete with exhibits by sponsoring companies. Sometimes these meetings can even appear so much like the real thing that they take in legitimate researchers and legitimate universities. Here, I present two examples of such conferences.
