The WHO's endorsement of TCM may have helped cause the coronavirus pandemic

About a year and a half ago, I wrote an article titled "WHO endorses Traditional Chinese Medicine. Expect deaths to rise." It went somewhat viral, with over 100,000 views, and then went quiet until last week, when it was revived on Twitter, which has driven thousands of new views to it. Multiple people asked me to re-visit it, in light of the coronavirus and its possible origin in a live animal market in China.

The deaths I was referring to in that title were the deaths of animals (as I'll explain below), not people. What I didn't write about–and what Twitter is buzzing about now–is the possibility that live animal markets in China, such as the one where the Covid-19 virus may have first infected humans, include bats sold for their use in traditional Chinese medicine, or TCM. We now know that the coronavirus almost certainly originated in bats. It's entirely possible–indeed, it seems very likely–that TCM is responsible for the emergence of the Covid-19 coronavirus.

The title of my article might have been more prescient than I guessed at the time.

Indeed, a just-published scientific paper pins the blame for Covid-19 squarely on TCM. The paper argues that

"a live or recently deceased infected bat species was handled by traders because of its value in TCM, and that such an infected individual, or the still infective bat or bat products, may have been the route by which the virus entered the exotic meat market in Wuhan."

Let's back up a bit and review the World Health Organization's involvement in this debacle. Just one year ago, the WHO added a chapter on TCM to its official International Classification of Diseases (ICD-11) for the first time. It apparently took this action after strong lobbying pressure from China: as a 2018 story in Nature pointed out:

"Over the past few years, [China] has been aggressively promoting TCM on the international stage both for expanding its global influence and for a share of the estimated US$50-billion global market."

This action by the WHO was the result of a long effort by its previous director (she left in 2017), Margaret Chan, who "worked closely with China" to get the WHO to endorse TCM.

Many scientists decried this action. The editors of Scientific American called it a "bad idea." Nature warned that it could "backfire," writing that it

"risks legitimizing an unfounded underlying philosophy and some unscientific practice.... Whatever its aims, the WHO’s chapter [on TCM] is unlikely to do anything other than fuel the expanding sales of largely unproven treatments."

TCM is not medicine. It's little more than a set of traditional beliefs (or a philosophy, as Nature called it) about various concoctions and their effect on one's health. Most of these beliefs have no evidence whatsoever that they provide any health benefits. Many of them derive from a pre-scientific view (which is not at all unique to China) that eating an animal gives one some of the properties of that animal. This is utter nonsense, of course.

Unfortunately, TCM is far from harmless, as I pointed out in my 2018 article. TCM has led to the horrific slaughter of the last remaining rhinoceroses in Africa in order to hack off their horns, which are sold to become part of elixirs that some people mistakenly think confer strength, virility, or other health benefits. Two years ago, National Geographic ran a heart-wrenching photo essay showing some of the awful results of rhinoceros poaching in Africa; take a look at these photos here (warning: these are very graphic).

TCM is behind the slaughter of the last remaining wild tigers, which are virtually extinct now in Asia, so that men can foolishly eat their bones, claws, and genitals in the mistaken belief that tiger parts will make them virile. Here too, National Geographic has details and photographs of cruel "tiger farms" that are almost too painful to look at.

TCM has also nearly wiped out pangolins, a completely harmless, gentle animal that has been killed in vast numbers because TCM practioners believe, wrongly, that its scale have some medicinal value. (They don't.) For more about this harmful practice, see this article I wrote in 2017.

And donkeys too: the Independent reported last November that "half the global population of donkeys could be wiped out in just five years, due to a surge in demand for their hides, which are used in traditional Chinese medicine." The world's donkey population is now in a state of crisis, according to the article, because of soaring demand in China for donkey hides, which are used to make eijao (donkey hide glue), a popular TCM product with no evidence that it has any medical benefits. Literally millions of donkeys are being slaughtered for nothing.

Before people accuse me of cultural insensitivity, let me add that there's no legitimate reason to use terms such as "Chinese" medicine, or American, Italian, Spanish, Indian, or [insert your favorite nationality] medicine. There's just medicine–if a treatment works, then it's medicine. If something doesn't work, then it's not medicine and we shouldn't sell it to people with false claims.

TCM has been a scam for decades: it was revived and heavily promoted in China by former dictator Mao Zedong, who didn't believe in it himself, but pushed it as a cheap alternative to real medicine. I won't go over that again here, but see these stories from Alan Levinovitz in Slate and David Gorski at Science-based Medicine.

The WHO is under new leadership now, but I see no sign that it's revising its endorsement of TCM, which is still lauded on the WHO website. Now we see that, in addition to the pointless slaughter of thousands of animals, some of which are likely to go extinct as a result, TCM might also create conditions that lead to new human pandemic diseases.

The new scientific paper that I mentioned above–the one that explains why trading in bat species for TCM may have caused the current pandemic, concludes that "a change in these practices is highly recommended."

That would be the understatement of the year.

It's sadly ironic that the WHO, which has in many ways been leading the fight against the Covid-19 virus, may have contributed to the conditions (live animal markets trading in wild animals) that allowed the virus to jump into the human population. It's too late to prevent that, but it's not too late for the WHO to take steps to prevent the next pandemic: they can and should remove TCM from their official guidelines.

As for China, they should recognize that the profits they make from the sales of animal parts for TCM are vastly outweighed by the harm these practices cause. China should stop promoting TCM, and it should ban the killing of wild animals for spurious medical reasons.

Why does anyone believe this works? The dangers of cupping.

Cupping therapy. If this looks painful and possibly damaging

to the skin, that's because it is.

People are easily fooled. Even smart people.

I'm not talking about voters in the U.S. and the UK, although both groups have recently demonstrated how easily they can be conned into voting against their own interests. You can read plenty of articles about that elsewhere.

No, I'm talking about the wide variety of health treatments that call themselves alternative medicine, integrative medicine, traditional Chinese medicine, energy medicine, and other names. These are all just marketing terms, but many people, including some physicians and scientists, seem captivated by them.

This week I'm going to look at "cupping," a rather bizarre treatment that, for reasons that escape me, seems to be growing in popularity.

I just returned from a scientific conference, where I happened to speak with an editor for a major scientific journal who also follows this blog. She remarked that she liked some of my articles, but she disagreed with me about cupping, which I wrote about during the 2016 Olympics, where swimmer Michael Phelps was observed to have the circular welts that are after-effects of cupping. This editor's argument boiled down to "it works for me," which left me somewhat flabbergasted.

And just two weeks ago, when I was at my physical therapist's office getting treatment for a shoulder injury, I heard her discussing cupping with another therapist. I then noticed a large box containing cupping equipment on one of the counters. Thankfully, my therapist didn't suggest cupping for me; I'm not sure how I would have replied.

What is cupping? It's a technique where you take glass cups, heat the air inside them, and then place them on the skin. Because hot air is less dense, it creates suction as it cools, which sucks your skin up into the glass. (Some cupping sets use pumps rather than heat to create this effect.) Imagine someone giving you a massive hickey, and then doing another dozen or so all over your back, or legs, or wherever the cupping therapist thinks you need it. If that sounds kind of gross, it is.

Quacktitioners Practitioners of cupping think that it somehow corrects your "qi," a mysterious life force that simply doesn't exist. When pressed, they often remark that it "improves blood flow," a catch-all explanation that has no scientific basis and that is more or less meaningless. What really happens, as the physician and blogger Orac noted, is this:

"The suction from cupping breaks capillaries, which is why not infrequently there are bruises left in the shape of the cups afterward.... If you repeatedly injure the same area of skin over time ... by placing the cups in exactly the same place over and over again, the skin there can actually die."

So maybe cupping isn't so good for you.

Cupping is ridiculous. There's no scientific or medical evidence that it provides any benefit, and it clearly carries some risk of harm. A recent review in a journal dedicated to alternative medicine–one of the friendliest possible venues for this kind of pseudoscience–concluded that

"No explicit recommendation for or against the use of cupping for athletes can be made. More studies are necessary."

Right. That's what proponents of pseudoscience always say when the evidence fails to support their bogus claims. Let us do more studies, they argue, and eventually we'll prove what we already believe. That's a recipe for bad science.

Even NCCIH, the arm of NIH dedicated to studying complementary and integrative nonsense medicine, can't bring itself to endorse cupping. Their summary states:

• There’s been some research on cupping, but most of it is of low quality.
• Cupping may help reduce pain, but the evidence for this isn’t very strong.
• There’s not enough high-quality research to allow conclusions to be reached about whether cupping is helpful for other conditions.

In other words, some bad scientists have conducted a few studies but haven't proven anything. But wait, it gets worse. NCCIH goes on to warn that:

• Cupping can cause side effects such as persistent skin discoloration, scars, burns, and infections, and may worsen eczema or psoriasis. 
• Rare cases of severe side effects have been reported, such as bleeding inside the skull (after cupping on the scalp) and anemia from blood loss (after repeated wet cupping). 

And still, otherwise intelligent people say "it works for me." I'm left speechless.

The bottom line: save your money and your skin. Don't let anyone suck it into those cups.

World Health Organization endorses TCM. Expect deaths to rise.

Mother and young rhinoceros killed for their horns.

A few days ago, a news story in the journal Nature reported that the World Health Organization, which is supposed to be devoted to improving the health and medical care of people around the globe, will for the first time endorse a belief system called "traditional Chinese medicine." I'm labeling TCM a belief system because that's what it is–but the WHO will be endorsing it as a set of medical practices.

The Nature writer, David Cyranoski, presents this news in a classic two-sides-of-the-story format, describing the "endless hours" that TCM proponents spent on such important topics as the "correct location of acupuncture points and less commonly known concepts such as ‘triple energizer meridian’ syndrome." Later in the article (but much later), he points out that scientists have argued that qi and meridians simply don't exist.

Cyranoski also falls into the trap of using the phrase "Western medicine" as if it were just an alternative point of view. An apt response is this comment from a biology Ph.D. student, who goes by @astrelaps on Twitter:

"What a weak, equivocal article from the world's preeminent scientific journal. "For those steeped in Western medicine..." is like writing "For those steeped in climate science" or "For those steeped in evolutionary biology" when reporting on climate change denial or creationism."

Well put. On the other hand, Cyranoski does point out that the major motivation for TCM is money:

"[China] has been aggressively promoting TCM on the international stage both for expanding its global influence and for a share of the estimated US$50-billion global market."

Were you thinking this was about health care? Afraid not. Cyranoski goes on to point out some serious problems with TCM, for example:

"Critics view TCM practices as unscientific, unsupported by clinical trials, and sometimes dangerous: China’s drug regulator gets more than 230,000 reports of adverse effects from TCM each year."

Actually, it's much worse than this.  Here's what TCM really looks like: the horrific slaughter of the last remaining rhinoceroses in Africa in order to hack off their horns, which are sold to become part of elixirs that some people mistakenly think confer strength or virility. Last year, National Geographic ran a heart-wrenching photo essay showing some of the awful results of rhinoceros poaching in Africa; take a look at these photos here.

TCM also looks like this: black bears kept in grotesquely cruel "farms" with a permanent tube inserted into their abdomens so that their bile can be harvested. Despite a growing movement to end this inhumane practice (see this NY Times story), it persists today, with thousands of bears kept in cages so small they can barely move. No one can view photos such as these and say that TCM is a good thing.

And TCM is behind the slaughter of the last remaining wild tigers, which are virtually extinct now in Asia, so that men can foolishly eat their bones, claws, and genitals in the mistaken belief that tiger parts will make them virile. Here too, National Geographic has details and photographs that are almost too painful to look at.

And don't get me started on pangolins, the beautiful, peaceful mammal that's now perilously endangered because TCM practitioners think its scales have some sort of medicinal value. (They don't.) For more on these gentle creatures, see the article I wrote last year.

I can almost hear the counter argument: but what about artemisinin? That's a plant extract derived from Artimisia annua, an herb that was traditionally used in China to treat malaria. Turns out that it really works, and artemisinin is now the basis of a number of modern malaria treatments.

Well, great. If an herb has the potential to treat disease, we should (and can, and do) study it, figure out what the active ingredient is, develop a controlled process for delivering effective doses, and use it. That's what happened with artemisia, and it also happened with taxol, an effective cancer chemotherapy derived from the Pacific yew tree, and common aspirin, derived from the willow tree.

But one success doesn't excuse hundreds of bogus claims that are based on little more than magical thinking.

There's no legitimate reason to use terms such as "Chinese" medicine, or American, Italian, Spanish, Indian, or [insert your favorite nationality] medicine. There's just medicine–if a treatment works, then it's medicine. If something doesn't work, then it's not medicine and we shouldn't sell it to people with false claims. The same is true for alternative, holistic, integrative, and functional medicine: these are all just marketing terms, with no scientific meaning. They merely serve to disguise sloppy, unscientific thinking at best, and in a less charitable interpretation, outright fraud.

As the Nature article points out, TCM has been a scam for decades: it was revived and heavily promoted in China by former dictator Mao Zedong, who didn't believe in it himself, but pushed it as a cheap alternative to real medicine. I won't go over that again here, but see these stories from Alan Levinovitz in Slate and David Gorski at Science-based Medicine.

Finally, why would the World Health Organization start pushing a set of unscientific practices that are likely to harm people's health? Support for TCM grew during the tenure of former WHO director Margaret Chan, who ran the WHO until 2017 and who had close ties to China. When Nature tried to contact Dr. Chan, the WHO responded that Chan "is not answering questions on matters related to the WHO."

By endorsing TCM, the WHO is taking a big step backwards. Let's hope that the current leaders of the WHO will realize that this step undermines their core mission. The WHO should not advocate treatments that not only have no evidence to support them and that can cause real harm to patients, but also are the primary reason that humans are hunting rhinoceroses, tigers, pangolins, and other animals to extinction.

World's cutest mammal critically endangered because of Traditional Chinese Medicine

A pangolin. Photo (c) Christian Boix.

Pangolins, timid little anteaters that are covered with scales, are being hunted to extinction. Why? Because some humans think their scales can be used as medicine. Pangolin scales are made of keratin, the same stuff that makes fingernails and claws, and they have no more medicinal value than any other fingernails–which is to say, none at all.

Pangolins are gentle, toothless mammals that eat ants with their long, sticky tongues. They are covered with scales (sort of like a walking artichoke) which protect them from predators but not from humans, who simply pick them up to harvest them. Baby pangolins ride, adorably on their mothers' tails or backs, as shown in the picture here.

How could someone look at these creatures and want to kill them? And yet pangolins are being slaughtered in large numbers because some practitioners of traditional Chinese medicine (TCM) think (wrongly!) that pangolin scales can treat nervousness or palsy. They are also being killed for meat: regrettably, pangolin meat and fetuses are considered a delicacy by some people in China.

Just a few months ago, the CITES organization (Convention on International Trade in Endangered Species) banned trade in all eight species of pangolins. We can only hope that this blanket ban is not too late. Previously CITES had declared that Asian pangolins were endangered, but had allowed trade in African pangolins, but because the meat is indistinguishable, the limited ban did little to stop the widespread killing of Asian pangolins. Just before the CITES meeting, Annamiticus (@annamiticus) reported that in the first nine months of 2016, 18,670 tons of pangolin scales from 19 countries had been seized from smugglers, mostly in Hong Kong. And that's just the amount that was stopped; many more tons doubtless slipped through.

Despite the new CITES restrictions, trade in pangolins continues. In December, customs officials in Shanghai arrested 3 people who were attempting to smuggle over 3 tons of pangolin scales into China. That shipment alone represents 5,000 to 7,500 pangolins that were killed for their scales.

Next Saturday (18 February) is World Pangolin Day. Let's hope that the new CITES restrictions, and greater public awareness of the endangered pangolin, can save these gentle animals from extinction.

*note: perhaps it's not the "world's cutest mammal," but the pangolin is still worth saving.

The worst quackery of 2011: battlefield acupuncture

Pseudoscience continued to thrive in 2011, making my choice for the worst quackery of the year a difficult one.  So much nonsense!  Promoters of both new age and old-time hocus pocus continued to sell their unscientific therapies, as they have for decades (or centuries), including homeopathy, Ayurveda, acupuncture, qigong, reiki, magnet therapy, and a cornucopia of special "super foods", all guaranteed to cure whatever ails you.  These various alternatives to medicine are just as ridiculous today as when they were invented, decades or centuries ago.

How can anyone choose the worst practice among so many false claims?  Well, those that cause real harm to patients are worse than those that are merely useless.  I also decided to give extra weight to newer forms of mumbo jumbo.  But I could have chosen differently, and I encourage readers to nominate their own favorites in the Comments section.

And the 2011 winner of the worst quackery award is: battlefield acupuncture.  This particular bizarre medical practice offers a trifecta of ills:

1. It offers no medical benefit and carries a real risk of harm for some patients.
2. The U.S. government is wasting tens of millions of dollars per year on it, and plans to increase its spending next year.
3. The patients are wounded combat veterans who have no choice about where to get treatment.

Battlefield acupuncture has a growing number of supporters in the U.S. Defense Department (especially Richard Niemtzow, its proud inventor), who are determined to see it delivered to as many troops as possible.  I've written about this before, but it's in the news again this month, in Wired magazine.  In battlefield acupuncture, the "doctor" (no competent doctor would do this) sticks needles into the patient's ear to relieve pain.  Yes, that's right: needles in the ear.

Battlefield acupuncture was invented out of whole cloth by military doctor Richard Niemtzow, who runs an acupuncture clinic out of Andrews Air Force Base in Maryland.  Niemtzow appears to be the leading advocate for the use of acupuncture on wounded soldiers, and he has been disturbingly effective.  The military publication Stars and Stripes reported in August that the Air Force has

"launched a program to train more than 30 military doctors to use acupuncture in the war zone and at their base clinics. The program will be expanded next year with the Air Force, Army and Navy combining funds for two courses to certify 60 active-duty physicians as medical acupuncturists."

Multiple scientific studies have shown clearly that acupuncture doesn't work. The benefit is the same no matter where you place the needles, or even if you use toothpicks that don't pierce the skin.  (See a summary here, with multiple references.)  Acupuncture points and "meridians" - the pathways that acupuncturists claim to manipulate with their needles - don't even exist.

Acupuncture carries a real risk of harm, too, primarily from infection.  Acupuncturists don't practice sterile procedure, as I've pointed out before.  They claim that they do, because they think that using sterilized needles is sufficient.  Wrong again.  Sterile procedure requires that every site of needle insertion be properly sterilized, because most infections are caused by bacteria already present on the skin.  As reported last year in BMJ:

"Although most patients recovered, 5-10% died of the infections and at least another 10% had serious consequences such as joint destruction, paraplegia, necrotising fasciitis, and multiorgan failure."  

Pretty serious harm from a procedure with no real benefit.

The evidence for "auricular acupuncture" - sticking needles in the ear - is less than zero.  This shouldn't be surprising, since Neimtzow just pulled this wacky theory out of thin air - but he and his converts have repeatedly asserted that it works, although they offer nothing more than anecdotes.  Niemtzow has even claimed that 18th-century pirates pierced their ears to improve their night vision.  Yes, really.  Now he's piercing the ears of wounded soldiers.

A big part of the Wired story is how the billionaire founders of the Samueli Institute, an institute dedicated to pseudoscience, have used their political muscle to obtain millions of dollars in Defense Department earmarks to support acupuncture research.  ($7.6 million in 2010, for example.)  Make no mistake, there's plenty of money in acupuncture, as in the rest of the alt-med industry.

But the real harm is in treating wounded soldiers by sticking needles in their ears, instead of offering real treatments.  To their credit, some soldiers are not fooled by Niemtzow's claims.  As a veteran over at Military.com said,

"In civilian medicine, this [battlefield acupuncture] would be called malpractice. This smacks of using military personnel in the field as guinea pigs. That's a dangerous game. If the pain of severe trauma isn't treated effectively in a timely manner, shock and even death can follow."

That discussion appeared in 2008, but three years later, Andrews Air Force Base has a full-time acupuncture clinic, and the military is training more doctors in this dangerous, ineffective, and highly unethical practice.  For this, battlefield acupuncture gets my award for the worst quackery of 2011.

(For further reading, see David Gorski's excellent takedown of battlefield acupuncture from 2008.)

Kill the tigers

Here's a choice: save the last remaining tigers on the planet, or kill them, chop them into pieces, and eat them in the mistaken belief that tiger parts can be used as medicine.

Sounds like an easy choice, no? Unfortunately, humans have already decided to kill the tigers rather than saving them. Fewer than 4,000 wild tigers survive on the planet. As journalist Caroline Alexander wrote in a compelling article in the December issue of National Geographic, "tigers in the wild face the black abyss of annihilation." And their greatest threat, she writes, is "the brutal Chinese black market for tiger parts."

Traditional Chinese Medicine (TCM) practitioners claim that tiger parts can be used to treat a wide variety of ailments, including malaria, bacterial infections, bad skin, ulcers, leprosy, and impotence. There is not a whit of scientific evidence to support any of these claims; they are nothing more than folk medicine, based on primitive beliefs dating from a pre-scientific era, when it was believed you could acquire the properties of an animal by eating it. Unfortunately, these beliefs have driven the mightiest of the big cats to the brink of extinction.

The World Federation of Chinese Medicine Societies asked its members to stop using tiger bones last year, but their action is far too little, too late. The New York Times reported around the same time that tiger-based "medicines" are widely available in China.

Proponents of Traditional Chinese Medicine claim that it is beneficial, but they have no science to back them up. NIH's National Center for Complementary and Alternative Medicine (NCCAM), an apologist for all sorts of quack medical practices, explains that

"In the TCM view, a vital energy or life force called qi circulates in the body through a system of pathways called meridians. Health is an ongoing process of maintaining balance and harmony in the circulation of qi."

This is little more than fantasy. Too bad NCCAM's leaders seem to have forgotten whatever they knew about human physiology. They might just as well explain that midi-chlorians circulating in the blood are the source of the Force. (Actually, there are midichlorians in nature now, in a species of tick.  Really.)

Some forms of "alternative medicine" are ineffective but mostly harmless (think homeopathy, which is just water and sugar pills), while others can be harmful to the patients who use them (think acupuncture, with its risk of infection, or ayurveda, which uses toxic chemicals). TCM is doubly harmful: it doesn't benefit patients, and it is the single greatest threat to the world's tigers. I hope people come to their senses before the last tiger is gone.

Pseudoscientific Chinese Medicine infiltrates scientific publishing

So it turns out that Chinese Medicine has its own journal, published by BioMed Central, a large scientific publisher. The Chinese Medicine journal promotes, according to its own mission statement, studies of "acupuncture, Tui-na, Qi-qong, Tai Chi Quan, energy research," and other nonsense. Tui na, for example, supposedly "affects the flow of energy by holding and pressing the body at acupressure points."

Right. What is this doing in a scientific journal? Actually, there are plenty of garbage journals out there, and I'd ignore this one like I do the others, but BioMed Central (and their owner, Springer Science) is a respectable publisher. It's also one of the largest open-access publishers, which means they make all their articles from their 213 journals freely available. I support BMC and I'm on the Editorial Boards for three of their journals (BMC Biology, BMC Genomics and BMC Bioinformatics). But their corporate leaders seem to care more about expanding their stable than about maintaining the integrity of science. Chinese Medicine simply does not belong in the company of respectable scientific journals.

What is "Chinese Medicine" anyway? (Should we also have journals for Russian Medicine, or American Medicine, or Swedish Medicine?) Actually, the name refers to what is usually called Traditional Chinese Medicine, or TCM. TCM is a grab-bag of superstitious practices taken from Chinese history, most of which are ineffective or even harmful. The most common justification for studying TCM (and using it on patients) is something along the lines of "this is an ancient Chinese practice" as if anything old must be worthwhile (also known as the argument from antiquity, a logical fallacy). But using the term "medicine" to describe Qi-gong, acupuncture, and "energy research" is, to put it bluntly, nonsense.

And by the way, "energy research" in this context doesn't refer to methods for producing electricity. No, the energy research in this journal refers to mysterious energy fields in the body, stuff like the "deqi" in this article from the January 2011 issue of Chinese Medicine: "Perception of Deqi by Chinese and American acupuncturists: a pilot survey." It's a laughably bad study, but here's a link for those with a high tolerance for quackery.

Ancient medicine was almost always bad medicine. People died very, very early in those good old days, and ancient China didn't have any special secrets. 2000 years ago, if you were lucky enough to survive past childood, you might just make it to your 30's. Life expectancy has climbed dramatically in recent times, for the past 150 years or so, thanks to modern hygiene and medicine. So forming a scientific journal whose goal is to validate antiquated, unproven superstitions is simply not science, whatever the editors of Chinese Medicine claim. The journal's claim to be "evidence-based" (yes, they do claim that) is little more than a smoke screen.

BioMed Central publishes at least one other pseudoscience journal, BMC Complementary and Alternative Medicine. BMC should be embarrassed to be publishing journals that promote anti-scientific theories and otherwise muddy the literature. By supporting these journals, they undermine the credibility of many excellent BMC journals. They should cut these journals loose.
