The Yale Experience with Alternative Medicine

 
Do you think that modern medical schools at major universities will never be advocates of quackery? Wrong!

The experience of Yale University's School of Medicine should be a warning that those who believe in evidence-based medicine have to be vigilant. Yale recently held an "Integrative Medicine Scientific Symposium." One of the speaker was David L. Katz, MD, MPH, FACPM, FACP. Katz is associate professor, adjunct, of Public Health and director of the Prevention Research Center (PRC) at the Yale University School of Medicine. He is a proponent of almost every form of non-evidence based medicine that you can imagine.

A short video of his presentation is included below. It's from the blog DC's Improbable Science: Integrative baloney @ Yale. I'm including it because it illustrates the length to which these quacks will go in order to make their point. Note that the quack is introduced by the Dean of Education at Yale—listen to how easily he may have been bamboozled into thinking that this is about legitimate science.

The most important points in the video are the ones where Dr. Katz explains away evidence-based medicine. You see, the problem isn't so much with the lack of "evidence" as with the concept of "evidence" itself. The practitioners of alternative medicine advocate changing the very concept of "evidence" to a "more fluid concept of evidence." What this means is that if a large-scale, double-blind experiment shows no effect it's not the end of the story. There are other kinds of evidence that may show the effectiveness of alternative medicine. (One of them seems to be anecdote.)



I hope that the University of Toronto is not going in this direction.

Snopes Warns Against Embedded Tracker Programs - Pass It on

 
Friday's Urban Legend: False

Have you ever received an email messgage like this?

Snopes Warning

Pass this one on to all your e-mail buddies and take the time to read the Snopes.com article listed below. It is full of good advice especially about the "cookies."

To whom it may concern:

Just a word to the wise. E-mail petitions are NOT acceptable to Congress or any other municipality. To be acceptable petitions must have a signed signature and full address.

Almost all e-mails that ask you to add your name and forward on to others are similar to that mass letter years ago that asked people to send business cards to the little kid in Florida who wanted to break the Guinness Book of Records for the most cards. All it was, and all this type of e-mail is, to get names and "cookie" tracking info for tele-marketers and spammers to validate active e-mail accounts for their own purposes.

Any time you see an e-mail that says forward this on to "10" of your friends, sign this petition, or you'll get good luck, or whatever, it has either an e- mail tracker program attached that tracks the cookies and e mails of those folks you forward to, or the host sender is getting a copy each time it gets forwarded and then is able to get lists of "active" e mails to use in spam e-mails, or sell to others that do.

Please forward this notice to others and you will be providing a good service to your friends, and will be rewarded by not getting 30,000 spam e-mails in the future.

(If you have been sending out the above kinds of email, now you know why you get so much spam!)

According to snopes.com they have never warned against "tracking programs" embedded in email messages [False Advice]. It may be good advice to not spam your friends but nothing in this email message is directly from the snopes.com website and nobody at snopes.com have authorized it.

If there was such a thing as an embedded email tracking program then passing on this message would be an excellent way to spread it!

Complimentary and Alternative Medicine at the University of Toronto

 
The Faculty of Arts & Science at the University of Toronto offers a program called "Human Biology." Students who complete the program will graduate with an Honours B.Sc. degree. One of the courses is HMB434H1: Complementary and Alternative Medicine.

The textbook for the course is Fundamentals of Complementary and Integrative Medicine by Marc S. Micozzi.

Here's the course description.

Complementary/ alternative medicine (“CAM”) is used in health care systems not only in North America, but also in countries such as China, India, and Vietnam (WHO, 2002). It involves the use of non-biomedical, “holistic” and/or culturally-specific health services and practices in the treatment of illness and disease (such as Chinese acupuncture), and an expanded concept of health, illness, and wellness. This course provides an introduction to the concepts, theoretical basis, evidence-based analysis, and pressing challenges and issues in CAM today. Specific topics include introductions to: complementary/ alternative medicine in industrialized countries and commonly used modalities such as homeopathy and naturopathic medicine; traditional medicine (TM) and primary health care (PHC); traditional Chinese Medicine (TCM) and China; Ayurvedic medicine in India; Canada’s First Nations; and integrative health systems and models. Course format includes lectures, guest-presentations, films/documentaries, and inter-active class discussions/exercises. Students will also have the opportunity to analyze CAM systems and modalities.

I've been pretty nervous about this course ever since one of our students blogged about it last year [U of T has a course in complementary and alternative medicine]. I was hoping that the course would present both sides of the story.

That idea was just blown out of the water at a meeting that I just returned from. I got a chance to talk to one of the instructors, Daniel Hollenberg. What I was hearing was not good so I steered to conversation around to homeopathy thinking that this might relieve my fears. It didn't.

Here, without comment, is what I was told by a man who teaches science students at my university.

• Philosphers of science recognize that there are several different kinds of evidence—not just the reductionist evidence of traditional medicine. In particular, epistemologists talk about holistic evidence. Alternative medicine is supported by holistic evidence not reductionist evidence.


• Evidence in support of homeopathy has been published in Lancet, and he teaches that to his students.


• While there may be examples of some homeopathic medicines that don't work, the theory of homeopathic medicine is understood and supported by physicists who have published papers explaining how water retains the memory of molecules that used to be dissolved in it. He mentioned Ursala Franklin as a supporter of homeopathy.

Nobel Laureates: George Hitchings and Gertrude Elion

 

The Nobel Prize in Physiology or Medicine 1988.

"for their discoveries of important principles for drug treatment"

Gertrude B. Elion (1918 - 1995) and George H. Hitchings (1905 - 1998) won the Noble Prize for their work on the treatment of disease and organ transplantation. They developed a number of drugs that interfered with nucleic acid synthesis leading to effective treatment of malaria as well as bacterial and viral infections. They are especially noted for the development of drugs that inhibit the body's ability to reject the transplant. One of the most famous of these immunosuppression drugs is azathioprine, a drug that is still used in some cases to suppress the immune response.

Elion and Hitchings worked together at the Wellcome Research Laboratories in Research Triangle Park, NC, USA. They are among a select group of Nobel Prize winners who did their prize winning research outside of academia. Elion and Hitchings shared the Nobel Prize with Sir James W. Black.

Here's what the press release said about Elion and Hitchings

THEME:

Studies of Nucleic Acid Synthesis Result in the Discovery of New Drugs

Gertrude Elion and George Hitchings have collaborated since 1945. Their original research idea was to look for differences in nucleic acid metabolism between normal human cells, cancer cells, protozoa, bacteria and virus, which could be utilized to develop drugs that selectively block the growth of cancer cells and of noxious organisms. Over the years this research philosophy has formed the basis for the development of drugs against a variety of disorders including leukemia, malaria, virus infections and gout.

When Elion and Hitchings presented their ideas at the end of the 1940s the knowledge about nucleic acid metabolism was very limited. It was known, however, that purines and pyrimidines are incorporated into nucleic acids. Elion and Hitchings studied the growth of the Lactobacillus casei, a bacterium dependent on folic acid or a combination of purines (hypoxanthine, guanine) and pyrimidines (thymine). The purpose was twofold, to characterize the metabolic pathways involved in the biosynthesis of nucleic acids and to identify antimetabolites in the nucleic acid metabolism (Figure 3).
Figure 3.

Figure 3. Purine bases (adenine, guanine and hypoxanthine) are synthesized from simple precursors. Nucleosides are then formed by the addition of sugar moieties (deoxyribose or ribose) and subsequently converted into nucleotides by the addition of phosphate (mono-, di- and triphosphate). Nucleotides take part in cellular metabolism and are the building blocks in the synthesis of RNA and DNA. Structural analogues of the natural substances can specifically block the different metabolic steps. Some examples are given in the figure.

Already in 1948 Elion and Hitchings discovered a substance, diaminopurine, an adenine antagonist, which inhibited the growth of L. casei (Figure 3). It was also found to have an effect on experimentally induced leukemia. Clinical trials in patients were initially promising but had to be interrupted due to toxic side effects. Stimulated by this finding Elion and Hitchings continued their research which soon resulted in two new chemotherapeutic drugs, thioguanine (1950) and 6-mercaptopurine (1951). In collaboration with the Sloan-Kettering Institute 6-mercaptopurine was tried in leukemic patients who were resistant to methotrexate. About one third of the patients responded with complete remission (1953). The finding was soon confirmed, and 6-mercaptopurine (as well as thioguanine) are still used in the treatment of leukemia (Table II).

Elion and Hitchings tried to improve the therapeutic properties of 6-mercaptopurine by using sulphur-substituted compounds. The result was azathioprine (1957) which replaced mercaptopurine as an inhibitor of the immune response. For a long time azathioprine was the only drug available to prevent rejection of transplanted organs. It is still used for that purpose but also for the treatment of autoimmune diseases.

Attempts were also made to prolong the effect of 6-mercaptopurine by blocking its metabolism by xanthine oxidase which is involved in the endogenous production of uric acid (Figure 3). In 1963 this research resulted in another new drug, allopurinol, which blocks the formation of uric acid and therefore is used in the treatment of primary and secondary gout.

Hitchings and collaborators also developed pyrimethamine (1950) and trimethoprim (1956) which were found to be effective in the treatment of malara and bacterial infections, respectively. Both drugs have a strong affinity to the enzyme dihydrofolate reductase, but pyrimethamine is 2000 times more toxic to the enzyme system in the malaria parasite than in the host. Trimethoprim has 100 000 times higher affinity to the bacterial compared to the human enzyme. An important discovery was that the chemotherapeutic effects of these two compounds were markedly enhanced by sulphonamides, drugs which inhibit the synthesis of folic acid. This pharmacotherapeutic principle is used in the combination drugs trimethoprim-sulfa and pyrimethamine-sulfa which are used in the treatment of bacterial infections and malaria, respectively.

A more recent application of Elion's and Hitchings' research philosophy is acyclovir, a drug used in the treatment of infections with herpes virus. Already in the 1950s they had shown that antipurines had to be transformed into nucleotides in order to become active in the cell. The herpes virus carries information which leads to the production of a new enzyme which transforms nucleosides to nucleotides (thymidine kinase) in the infected cell. This enzyme has considerably less substrate specificity than the cell's normal enzyme. Therefore, acyclovir is transformed into its corresponding nucleotide which is the active antimetabolite and the growth of the virus is inhibited (Figure 3).

Acyclovir was described by Elion and coworkers in 1977 and is a modern example of the realization of the basic ideas from 1950. An even more recent application of these ideas is the development of azidothymidine (AZT) which was described in 1985 by other scientists from the same institute, and which is the hitherto best documented drug in the treatment of AIDS. It can be added that trimethoprim-sulfa is used in the treatment of Pneumocystis carinii, a relatively common complication to AIDS.

The clinical use of the drugs discovered by Elion and Hitchings is summarized in Table II.
Table 2.

The IDiot Version of Reality

 
It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I’d rather not consider that).

Richard Dawkins
Check out this posting by Barry Arrington on Uncommon Descent [Peppered Moth Idolatry].

The venerable peppered moth (Biston betularia) has popped up a couple of times in recent posts. It seems that some of our Darwinian commenters (see, e.g., qwerty017 in comment [2] here) have not gotten the memo – the peppered moth myth has been completely exploded. Don’t take our word for it. Uber-Darwinist Jerry Coyne says in the November 1998 edition of Nature: “For the time being we must discard Biston as a well-understood example of natural selection in action.” Why else would the popular school text Biology pull its discussion of Biston as an example of “evolution in action”?

Here are some examples of scientists who have not heard message from the IDiot's.

Douglas Futuyma in his textbook Evolution published in 2005 (p. 293).

Until the 1930s, most evolutionary biologists followed Darwin in assuming that the intensity of natural selection is usually very slight. By the 1930s, however, examples of very strong selection came to light. One of the first examples was INDUSTRIAL MELANISM in the peppered moth (Biston betularia). ...

There are many scientific papers on the "myth" as well. Here's the abstract from Saccheri et al. (2008).

Historical datasets documenting changes to gene frequency clines are extremely rare but provide a powerful means of assessing the strength and relative roles of natural selection and gene flow. In 19th century Britain, blackening of the environment by the coal-fired manufacturing industry gave rise to a steep cline in the frequency of the black (carbonaria) morph of the peppered moth (Biston betularia) across northwest England and north Wales. The carbonaria morph has declined across the region following 1960s legislation to improve air quality, but the cline had not been comprehensively described since the early 1970s. We have quantified changes to the cline as of 2002, equivalent to an interval of 30 generations, and find that a cline still exists but that it is much shallower and shifted eastward. Joint estimation of the dominant fitness cost of carbonaria and dispersal parameters consistent with the observed cline change indicate that selection against carbonaria is very strong across the landscape (s approximately 0.2), and that dispersal is much greater than previously assumed. The high dispersal estimate is further supported by the weak pattern of genetic isolation by distance at microsatellite loci, and it implies that in addition to adult dispersal, wind-dispersed first instar larvae also contribute to lifetime dispersal. The historical perspective afforded by this study of cline reversal provides new insight into the factors contributing to gene frequency change in this species, and it serves to illustrate that, even under conditions of high dispersal and strong reverse selection acting against it, complete erosion of an established cline requires many generations.

Wow, this is a tough call. Who are you going to believe, evolutionary biologists like Futuyma and Sacheri et al., or an IDiot like Barry Arrington?

There's no rush. Take a microsecond or two to make up your mind.

See Revenge of the Peppered Moth. Ohmygod! These photographs are faked!, and Peppered Moths and the Confused IDiots for some insight into why one textbook got cold feet in 2000.

On the Origin of Species

 
Yesterday (Nov. 24, 2008) marked the 149th anniversary of the publication of On the Origin of Species by Charles Darwin. Ms. Sandwalk just bought me an illustrated edition by David Quammen and I highly recommend it. The text is from the first edition of Darwin's work and the illustrations cover a wide range of topics including copies of Darwin's letters and letters from his friends. This is an excellent way to get people interested in one of the most important books ever published.

I was prompted to re-read Origin and I discovered some things I had long forgotten. Most importantly, the style of Darwin's writing is impressive. He takes the time to argue his point by highlighting the most relevant objections to his ideas. While we all recognize that this is the appropriate style for a scientific work, we also recognize (unfortunately) that it may be a lost art. There are too many papers these days that ignore anything that weakens one's case.

In the four succeeding chapters, the most important and gravest difficulties on the theory will be given: namely, first, the difficulties of transitions, or in understanding how a simple being or a simple organ can be changed and perfected into a highly developed being or elaborately constructed organ; secondly, the subject of Instinct, or the mental powers of animals; thirdly, Hybridism, or the infertility of species and the fertility of varieties when intercrossed; and fourthly, the imperfection of the Geological Record.

The second thing I re-discovered is the clarity and forcefulness of Darwin's writing, given the style of the Victorian era. Also his foresight and originality.

Although much remains obscure, and will long remain obscure, I can entertain no doubt, after the most deliberate study and dispassionate judgment of which I am capable, that the view which most naturalists entertain, and which I formerly entertained—namely, that each species has been independently created—is erroneous. I am fully convinced that species are not immutable, but that those belonging to what are called the same genera are lineal descendants of some other and generally extinct species, in the same manner as the acknowledged varieties of any one species are the descendants of that species. Furthermore, I am convinced that Natural Selection has been the main but not the exclusive means of modification.

Thomas H. Huxley read an advance copy of On the Origin of Species and sent a letter to Darwin, which he received on the day before the book went public. Huxley knew what was coming ...

I trust you will not allow yourself to be in any way disgusted or annoyed by the considerable abuse and misrepresentation which, unless I greatly mistake, is in store for you. Depend upon it you have earned the lasting gratitude of all thoughtful men. And as to the curs which will bark and yelp, you must recollect that some of your friends, at any rate, are endowed with an amount of combativeness which (though you have often justly rebuked it) may stand you in good stead.

I am sharpening my claws and beak in readiness.

The letter is published in the illustrated edition by David Quammen.

Deceptive Science?

 
I was recently taken in by a paper where the authors implied that they were the first to identify one of Gregor Mendel's original genes [see Identity of the Product of Mendel's Green Cotyledon Gene (Update)].

The reason I was sensitized to this issue is because of a similar incident involving a paper published in Cell. Here's an outline of the issue as reported in The Times Higher Education.

It appears that the Cell paper is very misleading. It does not give appropriate credit to the work of other labs.

Peter Lawrence asked if he could publish a letter in Cell but he was told to post comments on the website instead. This is not appropriate. Nobody reads those comments. The author of the suspect Cell paper, Jeffrey Axelrod of Stanford School of Medicine (Palo Alto, CA USA) stands by his publication. The editors of Cell use the common excuse when a journal is caught with it's pants down.

After being sent four of the letters of complaint, Professor Axelrod added on the 6 November: "Our paper (Chen et al, June 2008) underwent a strict process of peer review prior to publication. Concerns about the review process should be directed to Cell. We stand by our conclusions as stated in the paper, as well as by our use of citations."

Cell declined to respond to questions put by Times Higher Education. However, in a response to the complaint from Professor Lawrence, Cell's senior scientific editor Connie Lee said: "I can only assure you that the reviewers were experts in planar cell polarity and the consensus decision was that the model presented by Chen et al was thought-provoking, well supported and provided a sufficient conceptual advance beyond the existing literature."

The incident raises a serious question. Is the pressure to publish so great that authors are tempted to deceive editors and reviewers by making their work seem more original and novel than it really is?

This is not a new problem. A few years ago Nature was pressured into publishing an editorial defending its policies against the charge that they were publishing bad science in order to be the first journal to publish "breakthroughs" (Adam and Knight, 2002). The Nature editorial denies that the popular journals are promoting sensationalism.

Editors of leading journals reject the suggestion that standards are slipping in the face of heightened competition. "Nature has nothing to gain by the pursuit of glamour at the expense of scientific quality, considering, not least, the criticisms, corrections and retractions we would then habitually be forced to publish," argued this journal in an editorial comment earlier this month5. And many researchers who were interviewed for this article agree that the system is still working tolerably. If it ain't broke, they say, don't try to fix it.

Speaking of the pursuit of glamour, Nature continues its policy of hiring science writers to promote and hype papers that have recently been published in its journal [Human genes are multitaskers].

Identity of the Product of Mendel's Green Cotyledon Gene (Update)

Last year I drew your attention to the identification of one of Gregor Mendel's original seven mutants [Identity of the Product of Mendel's Green Cotyledon Gene]. At the time, I thought that a recent 2007 paper by Sato et al. was the first publication to make this identification. Now I realize that I slighted the original discoverers Armstead et al. (2007) and earlier publications. The Armstead et al. paper is referenced in the later Sato et al. paper but the reference does not give appropriate credit to the work done by Armstead et al. in identifying the Mendelian gene. It was easy to get the impression that the Japanese group was the first to make the definite connection between Mendel's gene and work done in other species. I suspect that this was deliberate.

Here's a revised version of my original posting. Thanks to a reader who alerted me to the proper credit.

---

Another of Mendel's seven genes has been identified. This one is described in his 1865 paper Experiments in Plant Hybridization [MendelWeb] as character number 2.

2. To the difference in the color of the seed albumen (endosperm). The albumen of the ripe seeds is either pale yellow, bright yellow and orange colored, or it possesses a more or less intense green tint. This difference of color is easily seen in the seeds as their coats are transparent.

Mendel's reference to the color of albumin, or endosperm, is inaccurate. He was actually observing the color of the cotyledons—the "seed leaves" that surround the embryo in the pea seed. These tiny leaves are covered by a seed coat that is partially transparent.

In wild-type peas the seeds turn yellow as they mature (I) but certain mutants exhibit a "stay-green" phenotype where the peas retain their green color (i). The figure shows seeds from a plant with the II genotype (top) and the ii genotype (bottom). The seed coat has been removed from the lower pair of each group of four peas.

A paper published in Science identifies the "stay-green" gene that Mendel worked with (Armstead et al. 2007). This work is based on several decades of study of the "stay-green" phenotype by Howard Thomas and his colleagues at the Institute of Grassland and Environmental Research, Aberystwyth, UK (Armstead et al. 2006; Thomas, 1987; Thomas et al. 1996; Thomas and Stoddart, 1975).

It turns out that the gene, called sgr (stay-green), encodes an enzyme that is localized to chloroplasts and plays a role in the degradation of chlorophyll during senescence and maturation of seeds. When the enzyme is defective chlorophyll isn't broken down and the tissue stays green.

This brings to three the number of Mendel's genes that have a known function. The wrinkled pea phenotype is caused by a defect in the gene for starch branching enzyme (Bhattacharya et al., 1990) [Biochemist Gregor Mendel Studied Starch Synthesis]. The tall/short phenotypes are caused by defects in the gene for gibberellin 3β-hydroxylase (Martin et al., 1997). Gibberellins are plant growth hormones.

Monday's Molecule #98

 
Name this molecule. This time we need the common name and the systematic (IUPAC) name. A Nobel Prize was awarded for discovering this molecule and showing how it is involved in cell metabolism.

The first one to correctly identify the molecule and name the Nobel Laureate(s), wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first collected the prize. There are only three ineligible candidates for this week's reward: Dima Klenchin of the University of Wisconsin, Dale Hoyt from Athens, Georgia and Ms. Sandwalk from Mississauga, Ontario, Canada. Dale and Ms. Sandwalk have offered to donate the free lunch to a deserving undergraduate so the first two undergraduates to win and collect a free lunch can also invite a friend.

THEME:

Nobel Laureates
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the "molecule" and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Laureate(s) so you might want to check the list of previous Sandwalk postings by clicking on the link in the theme box.

Correct responses will be posted tomorrow. I reserve the right to select multiple winners if several people get it right.

Comments will be blocked for 24 hours. Comments are now open.

UPDATE: The molecule is azathioprine [6-(3-methyl-5-nitroimidazol-4-yl)sulfanyl-7H-purine]. The Nobel Laureates are Gertrude B. Elion and George H. Hitchings. Alex Ling of the University of Toronto beat everyone else so he gets another free lunch only this time he can invite a friend. There were a dozen people who got this one—that's a surprise to me since I had never even heard of the Nobel Laureates unitil last week.

A Fondness for Beetles

 
By now everyone has heard the story. There are almost as many species of beetle as all the rest of the insects put together. This is what prompted J.B.S. Haldane to say that God has "an inordinate fondness for beetles."

Now that's fine if you're an ordinary person, but if you're into taxonomy the huge diversity of beetles presents some really tough problems. Christopher Taylor describes one of the problems of classifying beetles in The Diversity of Ground Beetles.

Apparently God isn't the only one who likes beetles.

Best Canadian Sci/Tech Blog

 
The Canadian Blog Awards are for "Celebrating the best in the Canadian blogosphere." Here are the nominees for Best Sci/Tech Blog.

• AmberMac.com
• Climate Audit
• Sync, the Tech & Gadgets Blog
• Synchro Blogue
• 9th Sphere

I'm not sure why Bad Astronomy is on a list of blogs that celebrate the best in the Canadian blogosphere but that's who I voted for. I'm hoping that Phil Plait is NOT a Canadian 'cause that would point out how silly these awards really are.

Wouldn't it be funny if Mindful Hack or Post Darwinist won? That would say a lot about the people who vote for these things.

I support Canadian Cynic who refuses to participate ...

Another year, another incarnation of the Canadian Blog Awards, and another request to please delete CC HQ from any and all categories in which we've been nominated for a fairly simple reason -- we're not interested in any popularity contest in which voters seriously have to choose between CC HQ and batshit crazy, racist, white supremacist, Nazi sympathizer loons like Kate McMillan and Kathy Shaidle for "best blog."

I wish I could take the same stance but nobody nominated me for anything. Damn, I don't even get to withdraw my nomination.

BTW, I'm not familiar with most of these blogs. Can anyone point me to the wheat among all the chaff?

Canada's New Minister of State (Science and Technology) Is a Chiropractor

 
It's true. Checkout the Stephen Harper website, which incidentally, is supposed to be the Prime Minister's website.

The Honourable Gary Goodyear
Minister of State (Science and Technology)

Cambridge (Ontario)

Gary Goodyear was first elected to the House of Commons in 2004 and re-elected in 2006 and 2008.

Prior to entering federal politics, Dr. Goodyear practised chiropractic medicine and worked as an advisor to investment firms in the biomedical industry.

Dr. Goodyear was a co-designer of a three-year post-graduate sports fellowship program. He also co-authored “Practice Guidelines” and was Public Relations Director and Past President for the College of Chiropractic Sports Sciences in Toronto. Dr. Goodyear has taught at the Canadian Memorial Chiropractic College and the University of Waterloo. He has worked with many athletes, both amateur and professional, including serving as medical services chair for the Ontario Special Olympics.

Dr. Goodyear is a graduate of the University of Waterloo and the Canadian Memorial Chiropractic College.

It's bad enough that we have a chiropractor advising the government about science but this particular one seem especially unqualified. He also practiced acupuncture when he was actively seeing patients. Dr. (sic) Goodyear is strongly supported by evangelical christians (e.g. Christian Conservatives). That may not have anything to do with his ability to understand modern science. Gary Goodyear was endorsed by Vote Marriage Canada, a group that opposes gay marriage.

The website of the Canadian Memorial Chiropractic College has a lengthy article praising the 4 MPs who are chiropractors (3 Conservatives, 1 Liberal) [Chiros on the Hill].

“The single biggest criticism of politicians,” explains Dr. Colin Carrie, Class of ’89 and Member of Parliament for the electoral district of Oshawa, Ontario, “is that they don’t listen.” Chiropractors, he says, are educated to be exceptional listeners. “Regardless of our political stripes, we want to do what’s right for our patients and our constituents.”
It’s people skills, agrees his colleague and fellow Conservative Dr. Gary Goodyear (MP for Cambridge, Ontario). “Every chiropractor has to be a people person, that’s what we were taught at CMCC.”

Goodyear, Class of ’83, and Chair of the Committee of Procedure and House Affairs, adds with a laugh that his advisors have had occasion to remind him not to be quite so hands-on when dealing with his constituents. “My election team has actually told me to stop touching people so much, but I can’t help it. It’s just natural to me. As a chiropractor, you automatically love people. Chiropractic is a touchy-feely profession—that transfers.”

Interestingly, all four chiropractic MPs tell similar stories about how—for each in his or her own way—they have come to view their constituents in much the same light as chiropractors perceive their patients: “You can’t be a successful chiropractor without good interpersonal skills,” explains Dr. James Lunney, (Class of ’83, Nanaimo-Alberni, BC). “Our job as chiropractors is taking complicated issues, and finding ways of explaining them—interpreting X-rays, for example—you have to be able to communicate to your patient what needs to be communicated.” The job requirements are strikingly similar, he says, on Parliament Hill. “Any chiropractor who deals with patient issues successfully has the skills to make the transition into politics. If you can manage a practice, you have an aptitude for politics.”

I'm beginning to see the parallels between being a politician and a chiropractor. This is not complimentary to politicians.
