Dietary supplement industry says “no” to more information for consumers (again)

Once again, the dietary supplement industry is fighting efforts to give consumers more information about the safety and effectiveness of dietary supplements.

Big Supp is very clever. It sells consumers on the phony idea that they need dietary supplements for good health. Even as the evidence continues to mount that consumers don’t need supplements and shouldn’t take them, the industry continues to convince the public otherwise. And in 2011 they raked in $30 billion.

The state and federal governments have served as handmaidens to the industry in this clever marketing strategy. Congress’s gift to the supplement industry, the Orwellian-named Dietary Supplement Health and Education Act (DSHEA) “effectively excludes manufacturers of these products from virtually all regulations that are in place for prescription and over-the-counter drugs, and puts the requirement to demonstrate harm on the FDA, rather than the onus on the manufacturer to show a product is safe and effective,” as SBM’s Scott Gavura pointed out. DSHEA allows supplements to make “structure and function” claims, although no one seems to know what that means, including the FDA.

States have done their part in granting chiropractors and naturopaths the authority to give “nutritional” advice and recommend dietary supplements, sometimes on the basis of dubious diagnostic testing purporting to reveal imagined nutritional deficiencies. This gives them carte blanche to sell supplements to their patients, a clear conflict of interest.

And when proposed regulation threatens their profits, the dietary supplement industry and its surrogates enlist the very public it duped to join the battle. The industry convinces the public that someone is trying to take away their access to supplements they never needed in the first place. This threat is dressed up in terms designed to push all the buttons of a public already primed to be leery of “the government” – their “health freedom” may be taken away. Actually, freedom to choose among health care practices is most threatened by withholding readily-available information which would adequately inform health care decisions. (more…)

I refute it thus

Reality is one honey badger. It don’t care. About you, about your thoughts, about your needs, about your beliefs. You can reject reality and substitute your own, but reality will roll on, eventually crushing you even as you refuse to dodge it. The best you can hope for is to play by reality’s rules and use them to your benefit. Combined with a little luck (nothing quite as beneficial as being a white, middle class male in the US) you might have a reasonably healthy health.

The most reliable way to understand reality is science and the scientific method. Used wisely you may have a shot at minimizing morbidity and mortality. Deny or ignore it and reality don’t care. Reality will get us all.

We all have our biases, recognized and unrecognized. I often see the world in terms of infectious diseases. When I read Team of Rivals: The Political Genius of Abraham Lincoln I enjoyed the politics and personalities but I was struck by how people constantly died young of infectious diseases. We don’t see mortality in the young anymore for a variety of reasons: better nutrition, an understanding of the pathogenesis of disease, clean water, flush toilets and vaccines.

Danger Zones of Parental Vaccine Refusal

Back in 2009 I wrote a story entitled, “The New Plague”, about my experiences as a pediatrician with the frightening trend of parental vaccine refusal in New York City. In that post I discussed some of the complex social factors contributing to this phenomenon, and some of the common vaccine myths to which many parents fall prey. I recommend that you read that post, as it is (unfortunately) as timely today as it was then. Now I’m a pediatrician in Amherst, Massachusetts, and I find it necessary to revisit this dangerous trend in parenting.

As I described in my previous post on the subject, my old practice was at an interesting crossroads of several communities that seemed to perfectly embody the socioeconomic and cultural characteristics commonly found in communities with high rates of parental vaccine refusal. Ironically, these tend to include people who are educated and socially privileged; those empowered to question authority. In 2010, I left New York City and moved to Western Massachusetts to take a job at Baystate Children’s Hospital in Springfield. There I was in charge of the teaching clinic where pediatric residents are trained in the outpatient care of children. The children we took care of in Springfield comprised a very high-risk, underprivileged population. Our patients were significantly below the poverty level, with high rates of developmental and educational disability, a high teen pregnancy rate, and high rates of domestic violence, drug use, and gang involvement. Children who were not up to date with their vaccinations were behind because of poor continuity of care, with many missed appointments and gaps in follow-up. I now work at a private practice further north in the Pioneer Valley of Central Massachusetts. Here, my experiences with vaccine lapses are starkly different. Now, when I encounter a child who is not fully vaccinated or is completely unvaccinated, it is the result of a parental decision. A very flawed, dangerous, and misinformed parental decision.

California Acupuncturists Don’t Need to Know English!

English proficiency is not a necessary precursor to becoming a contributing citizen in California’s economy and should not be used by the Board to discriminate against talented and skilled individuals who seek to provide high-quality acupuncture services in California.

— State Senators Curren D. Price Jr. and Darrell Steinberg, letter to the California Acupuncture Board, March 22, 2013.

To appreciate the recklessness of this statement, and to illustrate the Senators’ disconnect with the reality of Oriental medicine, let’s take a look at a consummate example of services provided by acupuncturists. The following video features the “Master” Kim Nam-soo demonstrating his moxibustion technique. He conducted a similar workshop for future acupuncturists in 2010 at Emperor’s College of Traditional Oriental Medicine in Santa Monica, CA. Make sure you do not miss the part where the Master is skillfully adding his own spit to the treatment!

Kim Nam-Soo (also known as “Gudang”) is a 97-year-old acupuncturist from South Korea. In this video, he is teaching a form of moxibustion (burning of a mugwort cone on or near the skin). He is first preparing a wad of mugwort (Artemisia vulgaris), he is then placing it on an acupuncture point and burning it with an incense stick. Note that he is using his own saliva to make the mugwort more malleable before sticking it to the patient’s skin!

Besides acupuncture and moxibustion, the other services these “talented and skilled” individuals provide consist of massage, cupping, breathing techniques, and the use of herbal, animal and mineral products. In most states, bloodletting is not part of their scope of practice — except for Arkansas.

Preventing autism? Not so fast, Dr. Mumper…

Dug the Dog strikes again, as he did three weeks ago. I had a couple of ideas for a post this week, but none of them were time-sensitive or timely. Then, over the weekend, I saw a post on the antivaccine crank blog Age of Autism by Dan “Where are the Autistic Amish” Olmsted entitled Weekly Wrap: Another Medical Practice with a Sane Vaccine Schedule – and No Autism. Given the tendency towards a—shall we say?—lack of accuracy of Olmsted’s previous reporting, it’s no surprise that he’d latch on to this study. I’m also seeing it appear around other antivaccine websites. I had gotten wind of it late last week, a few of my readers having sent it to me but hadn’t decided yet whether to blog about it. Then it appeared on AoA. Thanks, Dan.

So let’s see how this study is being spun by the antivaccine movement:

When we at Age of Autism talk about ending the epidemic, the “to do” list seems almost overwhelming – funding a vax-unvaxed study, getting mercury out of flu shots, proving the HepB shot is nuts, wresting control of the agenda from pharma, fixing Vaccine Court (this time in the good sense of “fix”), establishing that biomedical treatments help kids recover, and on and on.

But there’s a shortcut to all this, and it goes straight through pediatricians’ offices. The evidence is growing that where a sane alternative to the CDC’s bloated vaccine schedule is offered, and other reasonable changes adopted, autism is either non-existent or so infrequent that it doesn’t constitute an epidemic at all.

The latest example comes from Lynchburg, Va., and the pediatric practice of Dr. Elizabeth Mumper. She noticed a frightening rise in autism in the 1990s. Concerned that vaccines and other medical interventions might be playing a role – concerned in other words that SHE was playing a role — Mumper changed course.

Fewer vaccines. Fewer antibiotics. No Tylenol. Breast-feeding. Probiotics. Good, pesticide free diets.

Since then, hundreds more children have been seen in her practice, Advocates For Children. But no more autism.

E-cigarettes: The growing popularity of an unregulated drug delivery device

This post is not about vaccines (for a change).

However, I deem it appropriate to mention that one of the topics that I blog most frequently about is vaccines and how the antivaccine movement pushes pseudoscience and quackery based on its apparently implacable hatred of vaccines. (You’ll see why very shortly.) It seems almost as long as my interest in the topic since I first noticed that the antivaccine movement acquired its very own celebrity spokesperson in Jenny McCarthy, who at least since 2007 has been promoting outrageous quackery and pseudoscience associated with her antivaccine views. To her, vaccines are chock full of “toxins” and all sorts of evil humors that will turn your child autistic in a heartbeat and in general “steal” your “real” child away from you the way she thinks vaccines “stole” her son Evan away from her. Indeed, among other “achievements,” she’s written multiple books about autism in which vaccines feature prominently as a cause, led a march on Washington to “green our vaccines” and has been the president of the antivaccine group Generation Rescue for the last few years. None of this stopped ABC from foolishly hiring her to join the regular cast on The View beginning in a few short weeks.

Because I occasionally check on what Jenny McCarthy is up to, I noticed a couple of weeks ago that she had been hired to be a celebrity spokesperson for blu™ e-cigarettes. Here she is, hawking the blu™ Starter Pack:

Prenatal Mercury and Autism

Mercury in unequivocally a neurotoxin. It is especially damaging to the developing brain. But it’s the dose that makes the toxin, and so a low enough exposure even to something known to be potentially harmful may not be. Further, the body has mechanisms for dealing with toxins, and toxins in the body may not be reaching the cells they can potentially damage in significant amounts. Therefore if we want to know if a potential toxin is actually causing any harm to people we need to do some type of epidemiological study – correlating exposure to possible adverse outcomes. All the studies in petri dishes and with cell cultures just won’t answer the question of harm.

The question of whether or not mercury in vaccines has caused neurological harm, specifically autism, has been largely answered. Numerous studies have shown no association between the amount of mercury exposure from vaccines and the risk of developing autism. A separate mercury-related question, however, is whether or not there is any risk of harm from mercury exposure from seafood. Mercury is methylated by bacteria into methymercury, and through them gets into the food chain in the oceans. Fish that eat other fish then concentrate the mercury in their tissues, and so predatory fish and sea mammals tend to have high concentrations of methymercury.

This has led to some precautionary recommendations, including that pregnant women should not eat tuna or other fish with high mercury levels. This makes sense, but what is the actual risk? The precautionary principle can also cut both ways. Fish contain many high-quality nutrients important for a developing brain, such as polyunsaturated fatty acids. Removing this food source from the diet of pregnant women may have unintended negative consequences.

Infant and Toddler Swimming Programs: Are They Safe and Effective?

It’s now officially summertime, but people have been hitting the pools and beaches for weeks in many parts of the nation. In fact it has been well into the 90’s for over two month here in Baton Rouge, which is what I blame for the early exit of LSU from the College World Series. Our boys just weren’t used to that cold and dry northern weather.

Not surprisingly, the media has already been busy reporting on some of the many tragic drowning incidents that have occurred thus far, and Facebook profiles have been full of commentary from worried parents. And, as usual, there are businesses offering infant and toddler swimming lessons costing hundreds and even thousands of dollars per course, some of which come with claims of decreasing the risk of drowning in the young participants.

At what age can a child begin swimming lessons? According to Jan Emler of Emler Swim School, teaching a child to swim can start “As soon as the umbilical cord falls off.” Emler, like more reputable proponents of infant and toddler swimming programs, doesn’t actually put newborns into swimming pools for lessons (I’ll leave water birthing enthusiasts out of this discussion). For the most part these programs only cover bath time activities to help younger babies grow comfortable being in the water. Truly teaching infants and toddlers behaviors aimed at reducing the likelihood of drowning in the event of falling into a body of water doesn’t usually start until 6 months of age. There are exceptions.

But when should these lessons start, are they safe and do they work? Or do they actually put children at risk of injury and the parent at risk of having a false sense of security? Until their updated 2010 policy statement on the prevention of drowning, the American Academy of Pediatrics came down firmly against initiating swimming lessons in children less than 4 years of age for a number of very good reasons. Why did they soften their stance and does their change of opinion support the claims that are being made by infant and toddler swimming programs?  First some background information.

The murder of autistic teen Alex Spourdalakis by his mother and caregiver: What happened?

Editor’s note: This is an extra “bonus” post. Basically, it’s a revised version of a post I did at my not-so-super-secret-other-blog last week. The issue, however, has disturbed me so much that I felt it appropriate to post it to SBM as well. Fear not. There will be a new post by yours truly on Monday.

Sometimes, in the course of blogging, I come across a story that I don’t know what to make of. Sometimes, it’s a quack or a crank taking a seemingly science-based position. Sometimes it’s something out of the ordinary. Other times, it’s a story that’s just weird, such that I strongly suspect that something else is going on but can’t prove it. So it was a few months ago when I came across the story of Alex Spourdalakis, a 14-year-old autistic boy who became a cause célèbre of the antivaccine crank blog Age of Autism.

I first noticed the story in early March when perusing AoA and came across a post by Lisa Goes entitled Day 19: Chicago Hospital Locks Down Autistic Patient. In the post was a shocking picture of a large 14-year-old boy in a a hospital bed in four-point restraints. He was naked, except for a sheet covering his genitals. A huge gash was torn in the bedsheet, revealing the black vinyl of the hospital bed beneath. The boy’s name, we were informed, was Alex Spourdalakis. Further down in the post was another, equally shocking, picture of Alex that, according to Goes, showed severe dermatitis on Alex’s back due to the hospital sheets. The photos shocked me for two reasons. First, if the story was as advertised (something always to be doubted about any story posted at AoA), for once I thought that I might be agreeing with Goes and thinking that AoA was actually doing a good thing, as disconcerting as that possibility was to me. Second, however, I was extremely disturbed by the publication of such revealing photos of the boy. Undoubtedly, Alex’s mother must have given permission. What kind of mother posts pictures like that of her son for all the world to see? Then there appeared a Facebook page, Help Support Alex Spourdalakis, which pled for readers to help the Spourdalakis family.

As I said, something just didn’t seem right at the time.

Don’t Text and Drive

We accept certain risks for the benefits of modern society. We pump explosive gas into homes, we run wires with potentially fatal electrical currents through our neighborhoods, and we ski at breakneck speeds down mountains for fun.

We also allow people to operate vehicles weighing thousands of pounds at speeds that are potentially deadly if a mishap occurs. In 2011 there were 32,367 motor vehicle deaths in the US (10.4 per 100,000 population). Interestingly, this is down quite a bit from previous years. As a percentage of population the highest motor vehicle death year was 1935, with 34,494 deaths, or 27.1 per 100,000. The highest absolute number of motor vehicle deaths was in 1970, at 52,627.

The number of deaths has been mostly trending down since 1996, which is interesting because over this same period of time cell phone use has risen tremendously. There are various reasons for the decreased in fatalities – helmet laws, seatbelt laws, cracking down on drunk driving, increased car safety, and intermediate drivers licenses for new drivers to name a few. These trends have probably obscured any increase in car accidents from using portable communication devices while driving.
