Connecticut “modernizes” naturopathic scope of practice

Naturopathy has been legal in Connecticut for almost 90 years, but with a scope of practice limited to counseling and a few treatments like physiotherapy, colonic hydrotherapy and “natural substances.” There was no specific authority to diagnose and treat. All of that changed on October 1, 2014, courtesy of the Connecticut legislature, which, in the words of the American Association of Naturopathic Physicians (AANP), “modernized” the naturopathic scope of practice.

Actually, the legislature did nothing of the sort. Naturopathy is based on the prescientific concept of vitalism, and we find it right there in the very first paragraph of the new law. Naturopathy is defined as:

diagnosis, prevention and treatment of disease and health optimization by stimulation and support of the body’s natural healing processes, as approved by the State Board of Natureopathic [sic] Examiners, with the consent of the Commissioner of Public Health. . .

Also included in the expanded scope of practice are:

ordering diagnostic tests and other diagnostic procedures, . . . ordering medical devices, including continuous glucose monitors, glucose meters, glucose test strips, barrier contraceptives and durable medical equipment; and . . . removing ear wax, removing foreign bodies from the ear, nose and skin, shaving corns and calluses, spirometry, tuberculosis testing, vaccine administration, venipuncture for blood testing and minor wound repair, including suturing.

Neuro-Acupuncture and Stroke

On the home page of Zhu’s Neuro-Acupuncture Center there is a video relaying a testimonial of how scalp acupuncture helped a patient recover from acute stroke. The use of testimonials is very common in the promotion of dubious health treatments. A personal story and endorsement is psychologically more compelling than dry data. Testimonials are completely unreliable, however, and in fact I would argue that they are ethically questionable. I would even go as far as saying that the presence of testimonials is almost a sure sign that the treatment being promoted is not legitimate.

What I could not find on Zhu’s website were links to published scientific researcher establishing the safety and efficacy of his treatments. You would think if they existed, he would display them prominently.

Acupuncture for stroke is a common claim, contradicting the notion that acupuncture is primarily used for the symptomatic treatment of subjective symptoms. That, in my experience, is part of the promotional strategy for many CAM treatments. They are presented as benign treatments for symptomatic treatment only, so what’s the possible harm. In reality, proponents will claim they can actually treat diseases whenever given the chance.

Does the Movie Fed Up Make Sense?

fed up movie

The 2014 film Fed Up is an advocacy documentary. Its message:

  • There is a worldwide epidemic of obesity.
  • It is endangering our children.
  • Increased sugar consumption is responsible.
  • The food industry is responsible for our increased sugar consumption because it puts hidden sugar in processed foods, bombards us with advertising, favors profits over health, and lobbies against regulation.
  • The government is responsible because it has failed to control the food industry.

The film has received mostly positive reviews and has been called the Inconvenient Truth of the health movement. It was written and directed by Stephanie Soechtig, whose earlier films attacked GMO foods and the bottled water industry, and narrated by Katie Couric, who “gave anti-vaccine ideas a shot” on her talk show in late 2013.

The film shows families struggling with childhood obesity and “experts” expressing their opinions. Their selection of “experts” is heavy on politicians and journalists and light on nutrition scientists.

Andrew Wakefield, the MMR, and a “mother warrior’s” fabricated vaccine injury story

AWakefield

As the time came to do my usual weekly post for this blog, I was torn over what to write about. Regular readers might have noticed that a certain dubious cancer doctor about whom I’ve written twice before has been agitating in the comments for me to pay attention to him, after having sent more e-mails to me and various deans at my medical school “challenging” me to publish a link to his results and threatening to go to the local press to see if he can drum up interest in this “battle.” I’ve been assiduously ignoring him, but over time the irritation factor made me want to tell him, “Be very careful what you ask for. You might just get it.” Then I’d make this week’s post about him, even though I wasn’t thrilled with the idea of giving in to his harassment and giving him what he wants.

That’s why I have to thank the ever-intrepid investigative reporter Brian Deer for providing me an alternative topic that is way more important than some self-important little quack and a compelling topic to blog about in its own right. Brian Deer, as you might recall, remains the one journalist who was able to crack the facade of seeming scientific legitimacy built up by antivaccine guru Andrew Wakefield and demonstrate that (1) Wakefield’s work concluding that the MMR vaccine was associated with “autistic enterocolitis” was bought and paid for by a solicitor named Richard Barr, who represented British parents looking to sue vaccine manufacturers, to the tune of over £400,000; (2) Wakefield expected to make over £72 million a year selling a test for which Wakefield had filed a patent application in March 1995 claiming that “Crohn’s disease or ulcerative colitis may be diagnosed by detecting measles virus in bowel tissue, bowel products or body fluids”; and Wakefield’s case series published in The Lancet in 1998 was fraudulent, the equivalent of what Deer correctly characterized as “Piltdown medicine.” Ultimately, these revelations led to Wakefield’s being completely discredited to the point where The Lancet retracted his paper and even Thoughtful House, the autism quackery clinic in Austin, TX where Wakefield had a cushy, well-paid position as scientific director, had to give him the boot. Yes, Wakefield is a fraud, and it’s only a shame that it took over a decade for it to be demonstrated.

As much as I hate how it took discrediting Wakefield the man as a fraud rather than just discrediting his bogus science to really begin to turn the tide against the annoying propensity of journalists to look to Wakefield or his acolytes for “equal time” and “balance” whenever stories about autism and vaccines reared their ugly heads, I can’t argue with the results. Wakefield is well and truly discredited now, so much so that, as I noted, his prominent involvement probably ruined any chance promoters of the “CDC whistleblower” scam ever had to get any traction from the mainstream press.

What is sometimes forgotten is the effect Wakefield’s message has had on parents. These are the sorts of parents who tend to congregate into groups designed to promote the idea that vaccines are dangerous and cause autism, such as the bloggers at the antivaccine crank blog Age of Autism, the equally cranky blog The Thinking Moms’ Revolution, or groups like The Canary Party. It is Wakefield’s message and the “autism biomed” quackery that it spawned that have led to unknown numbers of autistic children being subjected to the rankest form of quackery in order to “recover” them, up to and including dubious stem cell therapies and bleach enemas.

Brain-Based Learning, Myth versus Reality: Testing Learning Styles and Dual Coding 

Ed. Note: Today we present a guest post from Josh Cuevas, a cognitive psychologist and assistant professor in the College of Education at the University of North Georgia. Enjoy!

brain

Breaking the cycle

Since early on in graduate school when I began studying cognition, I’ve followed the learning styles movement because it was such a powerful phenomenon. It took hold rapidly, seemingly overnight, at all levels of education. And, like so many fads in education and science, it created a big-money industry involving conferences, training seminars, paid speakers, how-to manuals, and a variety of other mediums, inevitably linked to a profit in some way. Yet in the peer reviewed studies I was sifting through, evidence for learning styles was nowhere to be found. And more than a decade later I’m still looking for it.

Today when I suggest to students that learning styles are no more than a myth, I can hear their collective jaws drop, regardless of whether they’re undergraduates or graduate students, because learning styles have been preached to them the entire time they’ve been in school. The graduate students concern me the most because they’re supposed to know the research. And I used the term “preached” because these students have been convinced via no more than word of mouth, are asked to accept the information based on faith, and many come to hold a strange religious-like fervor for the concept. That’s not how science works and it shouldn’t be how education works.

It has been no easy task combating this common misconception in college classrooms, particularly when it is reinforced in textbooks, by other professors (who are also supposed to know the research), and in public schools where students do their internships. The research we’re doing at the University of North Georgia on learning styles has two purposes – it allows us to collect data on the effects of learning styles and contrast it to a stronger model, dual coding, but it also lets us demonstrate, in real time, to students who will one day be teachers how what they’ve long believed to be true simply does not work when put to the test.

Delaying School Start Times for Sleep Deprived Teens

010510-sleep-deprived-students-story

In August of this year, a new policy statement from the American Academy of Pediatrics was published which tackled the widespread problem of insufficient sleep in our adolescent population. They even went so far as to label insufficient sleep as “one of the most common, important, and potentially remediable health risks in children.” The statement, which gave a number of recommendations on how to address the problem, made the news rounds primarily because of the call for schools to delay start times until at least 8:30 AM.

I wrote about pediatric sleep in March for a post on the potential link between some sleep disorders in children, specifically nightmares and night terrors, and the development of psychosis. Those claims are suspect but please read that post for a review of what sleep is, why we need it, and what can go wrong with it in children of all ages. For this post, my focus will be on adolescent sleep specifically, and on the role of delaying school start times in improving a variety of health parameters.

What are the common adolescent sleep challenges?

The typical modern teenager faces a variety of challenges to consistently obtaining a full night’s sleep, which is considered by most sleep experts to be in the 8.5 to 9.5 hours per night range. This doesn’t mean that every teenager will fall apart if they only get 7 hours of sleep each night, but sub-optimal sleep can adversely affect school performance in many, and even lead to long-term health problems in some children who establish such a pattern during these pivotal years. Hold that thought for now, however.

One obvious reason for insufficient sleep in teenagers, at least it is likely obvious if you have one of your own or have ever spent more than two minutes near one, is technology. Most older children have electronic media in their rooms, if not attached to their bodies in the form of a smart phone. 24-7 access to the internet and social media is a commonly-cited impediment to sleep onset. The increasing availability and popularity of energy drinks containing absurd amounts of caffeine among adolescents likely also plays a role as both a coping strategy for daytime fatigue resulting from insufficient sleep, and as a cause of it. In fact, I think I’ve just come up with the topic for my next post.

Naturopathy vs. Science: Infertility Edition

This is another post in the naturopathy versus science series, where a naturopath’s advice is assessed against the scientific literature.

It’s Naturopathic Medicine Week in the United States, so it’s time for another look at the alternative medicine practice that a friend of the blog likes to call the One Quackery to Rule them All. Naturopathy is an oddity among alternative medicine, because it’s a hodgepodge of other practices linked by an underlying belief in vitalism: the pre-scientific notion that living things have a “life force”. Vitalism disappeared from medicine when Wöhler synthesized urea in 1828, yet the belief in vitalism is a central tenet of naturopathic philosophy. Naturopaths liken themselves to primary care providers comparable to family physicians (general practitioners) but their practices are quite different: rather than making decisions based on scientific evidence, naturopaths pick and choose based on what they feel is congruent with their vitalistic philosophy, sometimes despite good scientific evidence that shows they are wrong. For example, homeopathy is an alternative medicine practice that is very popular with naturopaths. It is an elaborate placebo system where “remedies” contain no medicinal ingredients: they are literally sugar pills. There is no demonstrable medical effect from homeopathy, and so it isn’t part of science-based medicine. Yet homeopathy is a “core clinical science” for naturopaths, and the practice of homeopathy is part of their licensing exam.

The Miracle Cure for Everything

cure_for_all_diseases_hulda

One common feature of pseudoscience is that proponents of a specific belief tend to exaggerate its scope and implications over time. In the world of physics this can eventually lead to a so-called “theory of everything” – one unifying theory that explains wide-ranging phenomena and displaces many established theories.

In medicine this tendency to exaggerate leads in the direction of the panacea, the miracle cure for everything. Why does this happen?

There are numerous examples. Here is a video of Bruce McBurney trying to sell his Precious Metals Nano Water to investors in the Dragon’s Den. The product is nothing but distilled water with a tiny amount of silver. McBurney claims that this magic water will essentially cure everything, all bacterial and viral infections, and even cancer.

The panacea is also not the sole domain of the lone crank. Straight chiropractors essentially believe that adjusting the spine can cure everything from bed wetting to asthma, and yes, even cancer.

What factors predispose to the panacea claim? (more…)

Why Does This Immunologist Reject Vaccinations?

Vaccination is arguably medicine’s greatest success. It has eradicated smallpox and has saved millions from death and suffering from a growing list of preventable diseases. It’s surprising that it has so many critics. Most of them are either not educated in medical science (like Jenny McCarthy) or are educated but prefer to reject science in favor of anecdotal experience (like Jay Gordon). Their arguments have been examined ad nauseum on this blog and elsewhere, and are easy to dismiss. But when I learned that an immunologist had written a book rejecting the whole idea of vaccination, I couldn’t dismiss it so easily. An expert in the field obviously knows more than I do about the relevant science; and if nothing else, she might have some valid criticisms of vaccines that I had overlooked. In 2012 Tetyana Obukhanych, PhD, published a short (53 page) book that is available in a Kindle edition: Vaccine Illusion: How Vaccination Compromises Our Natural Immunity and What We Can Do To Regain Our Health. I read the book hoping to learn something, and I did learn some things, but not anything that would make me question the current vaccine recommendations. I tried valiantly to understand her message; I think I succeeded. I’ll try to summarize what she is saying and explain why I think she got it wrong.

Breast cancer myths: No, antiperspirants do not cause breast cancer

antiperspirantbreastcancer

Four weeks ago, I wrote a post in which I explained why wearing a bra does not cause breast cancer. After I had finished the post, it occurred to me that I should have saved that post for now, given that October is Breast Cancer Awareness Month. The reason is that, like clockwork, pretty much every year around this time articles touting various myths about breast cancer will go viral, circulating on social media like Facebook, Twitter, Pinterest, and Tumblr like so many giant spider-microbes on the moon on Saturday. Sometimes, they’re new articles. Sometimes they’re old articles that, like the killer at the end of a slasher film, seem to have died but always come back for another attack, if not immediately, then when the next movie comes out.

So I thought that this October I should take at least a couple of them on, although I can’t guarantee that I’ll stick to the topic of breast cancer myths for the whole month. After all, our “atavistic oncology” crank (you remember him, don’t you?) is agitating in the comments and e-mailing his latest “challenge” to my dean, other universities, and me. It was almost enough for me to put this post on hold for a week and respond to our insistent little friend’s latest “evidence,” but for now I’ll just tell Dr. Frank Arguello, “Be very careful what you ask for. You might just get it.” Maybe next week. Or maybe on my not-so-super-secret other blog. Or maybe never. Because Dr. Arguello has officially begun to bore me.

In the meantime, I’m going to stick with the original plan, at least for now.

So, first up this week is a myth that I can’t believe that I haven’t covered in depth sometime during the nearly seven years of this blog’s existence, other than in passing a couple of times, even though it’s a topic that deserves its own post. I’m referring to the claim that antiperspirants cause breast cancer. I bet you’ve seen articles like this oldie but not so goodie from über-quack Joe Mercola entitled “Are Aluminum-Containing Antiperspirants Contributing To Breast Cancer In Women?” or this older and even moldier article from seven years ago entitled “Why women should avoid using anti-perspirants that could cause breast cancer” or this one from last year entitled “Attention Deodorant Users: New Studies Link Aluminum To Breast Cancer“. Surprisingly, I haven’t found that many from this year yet. (Maybe the Ebola scare is distracting the usual suspects and diverting their efforts.) The same ones, however, keep reappearing every year, and they’re all based on the same sorts of claims and the same studies. So let’s dig in, shall we? (more…)
