pseudo-science

A survey published in 2011 showed that one-third of Danish hospitals offered alternative therapies. In total, 38 hospitals offered acupuncture and one Eye Movement Desensitization and Reprocessing Light Therapy. The most commonly reported reason for offering CAM was “scientific evidence”.

Many readers of this blog might be amazed with both the high level of alternative medicine presence in Danish hospitals and the notion that this was due to ‘scientific evidence’. A recent article provides even more surprises about the Danish alternative medicine scene.

It revealed that 8 out of 10 Danes are interested in using some form of alternative medicine…Some 67 percent of Danes say the national healthcare system should be more open to alternative healing practices, such as homeopathy, acupuncture or chiropractic, and 60 percent would like to see these treatments covered by the public health insurance system. More than half of the 6,000 respondents believe alternative therapies can be just as effective as traditional medicine.

Charlotte Yde, the chairwoman at Sundhedsrådet, which is the umbrella organisation for alternative practitioners in Denmark, contends many Danes feel frustrated because they cannot freely discuss alternative treatment with their doctors. Alternative treatment researcher Helle Johannessen agrees that Danish doctors should openly discuss alternative medicine options with patients. “In other European countries doctors use alternative treatment to a much greater extent than doctors in Denmark,” Johannessen told DR. “[International experience] shows that some forms of alternative therapy can improve quality of life and reduce anxiety and nausea in cancer patients.”

This, it seems to me, is little more than a bonanza of fallacious thinking and misleading information.

  • The notion that popularity of a therapy has anything to do with its usefulness is a classical fallacy.
  • The notion that belief determines efficacy (More than half of the 6,000 respondents believe alternative therapies can be just as effective as traditional medicine.) or vice versa is complete nonsense.
  • The notion that many Danes … cannot freely discuss alternative treatment with their doctors is misleading: patients can discuss what they feel like with whom they feel like.
  • The notion that in other European countries doctors use alternative treatment to a much greater extent than doctors in Denmark is also misleading: there are many European countries where LESS alternative therapies are being paid for via the public purse.
  • Finally, the notion that that some forms of alternative therapy can improve quality of life and reduce anxiety and nausea in cancer patients – even if it were correct – does not mean that ALL alternative therapies are efficacious, safe, or cost-effective.

Who cares about Denmark?

Why should this be important?

Well, the Danes might care, and it is important because it provides an excellent example of how promoters of bogus treatments tend to argue – not just in Denmark, but everywhere. Unfortunately, politicians all too often fall for such fallacious notions. For them, a popular issue is a potential vote-winner. Within medical systems that are notoriously strapped for money, the looser will inevitably be optimal healthcare.

Yes, I admit it: over the years, I had formed a vague impression that homeopaths lack humour. Certainly, many comments on this blog seemed to confirm the notion. But now I changed my mind: some homeopaths are intensely funny.

Yesterday, I found a tweet which read: “NCH and homeopathy to be highlighted at the 2016 American Public Health Association’s conference in Denver”. The tweet provided a link which took me to an abstract authored by Alison Teitelbaum from the US National Center for Homeopathy (on their website, this organization tell us that they “inform legislators and work to secure homeopathy’s place in the U.S health care system while working to ensure that homeopathy is accurately represented in the media”).

The abstract in question summarized a presentation for the up-coming APHA-meeting in Denver. It is so hilariously comical that I simply have to share it with you (for those readers are homeopaths, I have added [in square brackets] a few footnotes explaining the humorous side of it):

Background: Over the last 25 years there has been a marked increase in consumer demand for information about complimentary [1] and alternative medicine, including homeopathy. Anecdotal data [2] suggest that homeopathic consumers are very satisfied with homeopathic medicines, and use them to treat acute, self-limiting conditions, however very little data exists in the published literature examining either topic [3]. Therefore, the purpose of this project was to evaluate homeopathic consumers’ use and satisfaction with homeopathic medicines.

Methods: Survey of nearly 20,000 consumers [4] who had purchased at least 1 over-the-counter (OTC) homeopathic medicine in the past 2 years.

Results: [5] More than 95% of respondents indicated they were very or extremely satisfied with the most recent OTC homeopathic medicine they had purchased and used [6]. More than 96% of respondents indicated they were very or extremely satisfied with the results of OTC homeopathic medicines that they had used in general [7]. Over 98% of respondents reported that they were very likely to purchase OTC homeopathic medicines again in the future [8]. More than 97% of respondents indicated that they were very likely to recommend homeopathic medicines to others [9]. Finally, more than 80% of respondents indicated using OTC homeopathic medicines for acute, self-limiting conditions, such as aches and pains; cold and flu symptoms; and digestive upset [10].

Conclusion: These results support anecdotal evidence [11] that homeopathic consumers are satisfied with OTC homeopathic medicines [12], and are using them to treat acute, self-limiting conditions [13]. Additional research is needed to further explore the use of OTC homeopathic medicine in the US for trends, access, and overall awareness about homeopathy [14].

[1] complimentary medicine = healthcare that costs nothing; complementary medicine = healthcare that complements real medicine; homeopathy should belong to the former category because it contains nothing.

[2] please note how ‘anecdotal data’ becomes ‘anecdotal evidence’ by the time we reach the conclusion; little does the author know that THE PLURAL OF ANECDOTE IS NOT ‘DATA’ BUT ‘ANECDOTES’!!!

[3] this statement implies that the author cannot cope with a Medline search, because there are plenty of articles on this subject.

[4] ‘nearly 20 000’ perfectly reflects the scientific rigor of this project (is it really too demanding to provide the exact figure?)

[5] how come we do not learn anything about the response rate of this survey (did ‘nearly’ everyone reply? or did ‘nearly’ everyone not reply?)?

[6] considering that only homeopathy-fans were included, this figure should be 100%!

[7] considering that only homeopathy-fans were included, this figure should be 100%!

[8] considering that only homeopathy-fans were included, this figure should be 100%!

[9] considering that only homeopathy-fans were included, this figure should be 100%!

[10] ‘more than 80%’ of an unknown rate of responders is about as much as a tin of peas. But I am nevertheless relieved that the majority used placebos merely for self-limiting conditions; the 20% who might have used it for life-threatening conditions are probably all dead – sad!

[11] see footnote number 2

[12] this is like doing a survey in a hamburger joint concluding that all consumers love to eat hamburgers.

[13] except, of course, the unknown percentage of non-responders who might all be dead.

[14] I would re-phrase this last sentence as follows: MORE SUCH PRESENTATIONS ARE NEEDED TO PROVIDE COMIC RELIEF TO OTHERWISE DRY AND BORING MEETINGS ON PUBLIC HEALTH.

Yes, I know, lately I have been neglecting my ‘ALT MED HALL OF FAME’. This is entirely my fault; there are so many candidates waiting to be admitted that, I have been hesitant as to who should be next. Today, I came across an article about Deepak Chopra and his latest book, Super Genes. It tells “how lifestyle shifts can help you reboot your health at a genetic level.” If it were just for this single sentence, he would deserve to be admitted – no, not into what you just thought, into the ‘ALT MED HALL OF FAME’, of course’.

I will save you the expense of buying his book (don’t worry, Deepak is already a multi-millionaire) by repeating what the article said about his ‘6 pillars of wellbeing’ (another cracker!!!):

DIET

• A typical modern diet is very likely to cause inflammation, which research has linked to many chronic diseases and obesity.

• To reduce inflammation, add prebiotics – substances that buffer the body from inflammation – such as oatmeal, pulpy orange juice, bran cereal and bananas to your breakfast.

• Consume probiotics – foods that contain active bacteria – once a day for gut health. These foods include active yoghurt, pickles and sauerkraut.

• Eat mindfully – eat only when you’re genuinely hungry and stop when you are full.

• Reduce snacking by eating only one measured portion in a bowl; never eat straight from a bag or packet.

STRESS

• Three factors generally lie behind the problem of chronic stress: repetition, unpredictability and a lack of control. Think of a dog barking outside your window; you don’t know when it will end and you have no way of stopping it.

• Decrease background noise and distractions at work. Also, avoid multitasking by dealing with one thing at a time.

• Leave work on time at least three times a week and don’t bring work home. Leave the office at the office.

• Avoid people who are sources of pressure and conflict. Even normal office behaviour, such as forming cliques and gossiping, is a source of stress that has the potential to be emotionally devastating.

• If you struggle to deal with negative emotions, ask your doctor about cognitive behaviour therapy.

EXERCISE

• The secret to exercise is this: keep going and don’t stop. It’s better to be active all your life at a lower level, rather than to be at a near professional-level in high school, say, and then stop completely.

• At work get up and move around once an hour and devote half your lunch break to movement, even if it’s walking around the block.

• Be in nature more: go outside for five to 10 minutes three times a day.

• Acquire more active friends and join them in their activities. Plan a shared exercise activity with your spouse or friends twice a week.

• Make leisure time more creative – think beyond TV or internet.

• Volunteer to help the needy with housecleaning, painting and repairs.

This will serve as both exercise and a morale boost.

MEDITATION

• Meditate every day for 10 minutes.

Sit with your eyes closed in a quiet place, put your attention on the tip of your nose and focus on the sensation of your breath coming in and out of your nostrils.

• Don’t look at meditation as an aid for the bad days you experience (“I’m feeling good today, so I don’t need to meditate”). It should be a lifelong practice.

• Take 10 minutes out of your lunch break to sit alone with eyes closed, preferably outside in nature.

• Notice what a relief it is to take big deep breaths when you are upset or nervous, and how ragged your breath becomes when you are anxious or stressed.

• Join an organised meditation course in your area. Search for meetup.com to find local groups that meet all around the country.

SLEEP

• Make your bedroom as dark as possible. If total darkness is impossible, wear a sleep mask.

• Drink a glass of warm almond milk, which is rich in calcium and promotes melatonin, a hormone that helps to regulate the sleep-wake cycle.

• Experiment with herbal teas associated with good sleep such as chamomile, valerian, passionflower, lavender and kava kava.

• Explore abhyanga, a self-massage technique that uses warmed sesame oil, lightly massaged into arms, legs, neck and torso (go to YouTube to see tutorials).

• Don’t ignore insomnia. In some studies sleep disorders have been associated with triggering Alzheimer’s disease and are also associated with high blood pressure.

EMOTIONS

• Take responsibility for your feelings. Wellbeing depends upon happiness, yet most people don’t really make that connection.

• Write down five specific things that make you happy and, on a daily basis, do at least one of them.

• Set a “good news policy” at meal times, whether it’s the radio station you choose to listen to or the topic of conversation around the table.

• Explore a time in your past when you were happy and learn from it, whether that means re-embracing an old hobby or getting in touch with an old friend.

• Become comfortable with delayed gratification – consider how your choices will make you feel in the future as well as today.

END OF QUOTE

My favourite website about Deepak Chopra is the one by Tom Williamson. It states that “it has been said by some that the thoughts and tweets of Deepak Chopra are indistinguishable from a set of profound sounding words put together in a random order, particularly the tweets tagged with “#cosmisconciousness”. This site aims to test that claim! Each “quote” is generated from a list of words that can be found in Deepak Chopra’s Twitter stream randomly stuck together in a sentence.” It seems to me that Deepak himself might have made ample use of this site for writing his latest book, and if you should ever run out of platitudes or empty phrases, this site will serve you well.

Deepak has published plenty of best-sellers, but he has as good as nothing to show for himself in the peer-reviewed medical literature. (When you are that famous, you obviously don’t need to bother anymore with trivia such as evidence, science and all that jazz.) This means that I had to deviate from my usual admission criteria for the “prophet of alternative medicine”, as Deepak likes to be called. But he is well worth making an exception, I am sure you agree, he is the absolute super-star!

Super-star of what?

I let you decide!

 

Homeopaths assume lots of things; one of their main claims is, for instance, that the process of repeatedly diluting a remedy and vigorously shaking it at each step – they call this potentisation – renders it more potent. This is the famous MEMORY OF WATER’ theory of homeopathy. In Hahnemann’s own words: ‘…the power of a medicine in solution is much increased by intimate mixture with a large volume of fluid…’ And elsewhere he stated that ‘as the smallest quantity of medicine naturally disturbs the organism least, we should choose the very smallest doses, provided always that they are a match for the disease… hardly any dose of the homeopathically selected remedy can be so small as not to be stronger than the natural disease…’

Hahnemann’s explanation for this extraordinary assumption (which he claimed to have observed empirically) was that his remedies do not work through any material effects but via spirit-like energies. As this sounds a little silly in the light of modern science, homeopaths have been keen to find more rational support for their theories. Thus they have developed several ‘sciency’ concepts to explain the mode of action of their highly diluted homeopathic remedies. For instance that postulated that water can form secondary structures that hold some information of the original substance (stock), even if it has long been diluted out of the remedy. Alternatively, they claimed that the shaking of the remedy generates nano-particles or silicone-particles which, in turn, are the cause of the clinical effects.

Today, I want to assume for a minute, that one of these theories is correct – they cannot all be right, of course. Homeopaths regularly show us investigations that seem to support them, even though it only needs a real expert in the particular field of science to cast serious doubt on them. I will nevertheless assume that, after potentisation, the diluent retains information via nano-particles or some other phenomenon. For the purpose of this mind-experiment, I grant homeopaths that, in this respect, they are correct. In other words, let’s for a moment assume that the ‘memory of water’ theory is correct.

As I have been more than generous, I want homeopaths to return the favour and consider what this would really mean: information has been transferred from the stock to the diluent. Does that prove anything? Does it show that homeopathy is valid?

Could the homeopaths who make this assumption be equally generous and answer the following questions, please?

  1. How does a nano-particle of coffee, for instance, affect the sleep centre in the brain to make the patient sleep? Or how does a nano-particle of the Berlin Wall or a duck liver affect anything at all in the human body? The claim that information has been retained by the diluent is no where near to an explanation of a rational mode of action, isn’t it?
  2. Most homeopathic remedies are consumed not as liquids but as ‘globuli’, i. e.  tiny little pills made of lactose. They are prepared by dropping the liquid remedy on to them. The liquid subsequently evaporates. How is it that the information retained in the liquid does not evaporate with the diluent?
  3. The diluent usually is a water-alcohol mixture which inevitably contains impurities. In fact, a liquid C12 remedy most certainly contains dimensions more impurities than stock. These impurities have, of course, also been vigorously shaken, i. e. potentised. How can we explain that their ‘potency’ has not been beefed up at each dilution step? Would this not necessitate a process where only some molecules in the diluent are agitated, while all the rest remain absolutely still? How can we explain this fantastic concept?
  4. Some stock used in homeopathy is insoluble (for instance Berlin Wall). Such stock is not diluted but its concentration in the remedy is initially lowered by a process called ‘trituration’, a process which consists in grinding the source material in another solid material, usually lactose. I have granted you that potentisation works in the way you think. But how is information transferred from one solid material to another?
  5. Everything we drink is based on water containing molecules that have been inadvertently potentised in nature a million times and therefore should have hugely powerful effects on our bodies. How is it that we experience none of these effects each time we drink?

Now, homeopaths, let me propose a deal.

If you can answer these questions satisfactorily, I will no longer doubt your memory of water theory. If you cannot do this, I think you ought to admit that all your ‘sciency’ theories about the mode of action of highly diluted homeopathic remedies are really quite silly – more silly even than Hahnemann’s idea of a ‘spirit-like’ effect.

 

The ACUPUNCTURE NOW FOUNDATION (ANF) have recently published a document that is worth drawing your attention to. But first I should perhaps explain who the ANF are. They state that “The Acupuncture Now Foundation (ANF) was founded in 2014 by a diverse group of people from around the world who were concerned about common misunderstandings regarding acupuncture and wanted to help acupuncture reach its full potential. Our goal is to become recognized as a leader in the collection and dissemination of unbiased and authoritative information about all aspects of the practice of acupuncture.”

This, I have to admit, sounds like music to my ears! So, I studied the document in some detail – and the music quickly turned into musac.

The document which they call a ‘white paper’ promises ‘a review of the research’. Reading even just the very first sentence, my initial enthusiasm turned into bewilderment: “It is now widely accepted across health care disciplines throughout the world that acupuncture can be effective in treating such painful conditions as migraine headaches, and low back, neck and knee pain, as well as a range of painful musculoskeletal conditions.” Any review of research that starts with such a deeply uncritical and overtly promotional statement, must be peculiar (quite apart from the fact that the ANF do not seem to appreciate that back and neck pain are musculoskeletal by nature).

As I read on, my amazement grew into bewilderment. Allow me to present a few further statements from this review (together with a link to the article provided by the ANF in support and a very brief comment by myself) which I found more than a little over-optimistic, far-fetched or plainly wrong:

Male fertility, especially sperm production and motility, has also been shown to improve with acupuncture. In a recent animal study, electro-acupuncture was found to enhance germ cell proliferation. This action is believed to facilitate the recovery of sperm production (spermatogenesis) and may restore normal semen parameters in subfertile patients.

The article supplied as evidence for this statement refers to an animal experiment using a model where sperm are exposed to heat. This has almost no bearing on the clinical situation in humans and does not lend itself to any clinical conclusions regarding the treatment of sub-fertile men.

In a recent meta-analysis, researchers concluded that the efficacy of acupuncture as a stand-alone therapy was comparable to antidepressants in improving clinical response and alleviating symptom severity of major depressive disorder (MDD). Also, acupuncture was superior to antidepressants and waitlist controls in improving both response and symptom severity of post-traumatic stress disorder (PTSD). The incidence of adverse events with acupuncture was significantly lower than antidepressants.

The review provided as evidence is wide open to bias; it was criticised thus: “the authors’ findings did not reflect the evidence presented and limitations in study numbers, sample sizes and study pooling, particularly in some subgroup analyses, suggested that the conclusions are not reliable”. Moreover, we need to know that by no means all reviews of the subject confirm this positive conclusion, for instance, thisthis, or this one; all of the latter reviews are more up-to-date than the one provided by ANF. Crucially, a Cochrane review concluded that “the evidence is inconclusive to allow us to make any recommendations for depression-specific acupuncture”.

“A randomized controlled trial of acupuncture and counseling for patients presenting with depression, after having consulted their general practitioner in primary care, showed that both interventions were associated with significantly reduced depression at three months when compared to usual care alone.”

We have discussed the trial in question on this blog. It follows the infamous ‘A+B versus B’ design which cannot possibly produce a negative result.

Now, please re-read the first paragraph of this post; but be careful not to fall off your chair laughing.

There would be more (much more) to criticise in the ANF report but, I think, these examples are ENOUGH!

Let me finish by quoting from the ANF’s view on the future as cited in their new ‘white paper’: “Looking ahead, it is clear that acupuncture is poised to make significant inroads into conventional medicine. It has the potential to become a part of every hospital’s standard of care and, in fact, this is already starting to take place not only in the U.S., but internationally. The treatment is a cost-effective and safe method of relieving pain in emergency rooms, during in-patient stays and after surgery. It can lessen post-operative nausea, constipation and urinary difficulties, and have a positive impact on conditions like hypertension, anxiety and insomnia…

Driven by popular demand and a growing body of scientific evidence, acupuncture is beginning to be taken seriously by mainstream conventional medicine, which is incorporating it into holistic health programs for the good of patients and the future of health care. In order for this transition to take place most effectively, misunderstandings about acupuncture need to be addressed. We hope this white paper has helped to clarify some of those misunderstandings and encourage anyone with questions to contact the Acupuncture Now Foundation.”

My question is short and simple: IGNORANCE OR FRAUD?

 

Yes, yes, yes, I know: we have too few women in our ‘ALT MED HALL OF FAME’. This is not because I have anything against them (quite the contrary) but, in alternative medicine research, the boys by far outnumber the girls, I am afraid.

You do remember, of course, you has previously been admitted to this austere club of excellence; only two women so far. Here is the current list of members to remind you:

David Peters (osteopathy, homeopathy, UK)

Nicola Robinson (TCM, UK)

Peter Fisher (homeopathy, UK)

Simon Mills (herbal medicine, UK)

Gustav Dobos (various, Germany)

Claudia Witt (homeopathy, Germany and Switzerland)

George Lewith (acupuncture, UK)

John Licciardone (osteopathy, US)

If you study the list carefully, you will also notice that, until now, I have totally ignored the chiropractic profession. This is a truly embarrassing omission! When it comes to excellence in research, who could possibly bypass our friends, the chiropractors?

Today we are going to correct these mistakes. Specifically, we are going to increase the number of women by 50% (adding one more to the previous two) and, at the same time, admit a deserving chiropractor to the ALT MED HALL OF FAME.

Cheryl Hawk is currently the Executive Director of Northwest Center for Lifestyle and Functional Medicine, University of Western States, Portland, USA. Previously she worked as Director of Clinical Research at the Logan University College of Chiropractic, Chesterfield, USA, and prior to that she was employed at various other institutions. Since many years she has been a shining light of chiropractic research. She is certainly not ‘small fry’ when it comes to the promotion of chiropractic.

Cheryl seems to prefer surveys as a research tool over clinical trials, and it was therefore not always easy to identify those of her 67 Medline-listed articles that reported some kind of evaluation of the value of chiropractic. Here are, as always, the 10 most recent papers where I could extract something like a data-based conclusion (in bold) from the abstract.

Best Practices for Chiropractic Care of Children: A Consensus Update.

Hawk C, Schneider MJ, Vallone S, Hewitt EG.

J Manipulative Physiol Ther. 2016 Mar-Apr;39(3):158-68

All of the seed statements in this best practices document achieved a high level of consensus and thus represent a general framework for what constitutes an evidence-based and reasonable approach to the chiropractic management of infants, children, and adolescents.

Clinical Practice Guideline: Chiropractic Care for Low Back Pain.

Globe G, Farabaugh RJ, Hawk C, Morris CE, Baker G, Whalen WM, Walters S, Kaeser M, Dehen M, Augat T.

J Manipulative Physiol Ther. 2016 Jan;39(1):1-22

The evidence supports that doctors of chiropractic are well suited to diagnose, treat, co-manage, and manage the treatment of patients with low back pain disorders.

The Role of Chiropractic Care in the Treatment of Dizziness or Balance Disorders: Analysis of National Health Interview Survey Data.

Ndetan H, Hawk C, Sekhon VK, Chiusano M.

J Evid Based Complementary Altern Med. 2016 Apr;21(2):138-42.

The odds ratio for perceiving being helped by a chiropractor was 4.36 (95% CI, 1.17-16.31) for respondents aged 65 years or older; 9.5 (95% CI, 7.92-11.40) for respondents reporting head or neck trauma; and 13.78 (95% CI, 5.59-33.99) for those reporting neurological or muscular conditions as the cause of their balance or dizziness.

US chiropractors’ attitudes, skills and use of evidence-based practice: A cross-sectional national survey.

Schneider MJ, Evans R, Haas M, Leach M, Hawk C, Long C, Cramer GD, Walters O, Vihstadt C, Terhorst L.

Chiropr Man Therap. 2015 May 4;23:16.

American chiropractors appear similar to chiropractors in other countries, and other health professionals regarding their favorable attitudes towards EBP, while expressing barriers related to EBP skills such as research relevance and lack of time. This suggests that the design of future EBP educational interventions should capitalize on the growing body of EBP implementation research developing in other health disciplines. This will likely include broadening the approach beyond a sole focus on EBP education, and taking a multilevel approach that also targets professional, organizational and health policy domains.

Chiropractic identity, role and future: a survey of North American chiropractic students.

Gliedt JA, Hawk C, Anderson M, Ahmad K, Bunn D, Cambron J, Gleberzon B, Hart J, Kizhakkeveettil A, Perle SM, Ramcharan M, Sullivan S, Zhang L.

Chiropr Man Therap. 2015 Feb 2;23(1):4

The chiropractic students in this study showed a preference for participating in mainstream health care, report an exposure to evidence-based practice, and desire to hold to traditional chiropractic theories and practices. The majority of students would like to see an emphasis on correction of vertebral subluxation, while a larger percent found it is important to learn about evidence-based practice. These two key points may seem contradictory, suggesting cognitive dissonance. Or perhaps some students want to hold on to traditional theory (e.g., subluxation-centered practice) while recognizing the need for further research to fully explore these theories. Further research on this topic is needed.

Do informed consent documents for chiropractic clinical research studies meet readability level recommendations and contain required elements: a descriptive study.

Twist E, Lawrence DJ, Salsbury SA, Hawk C.

Chiropr Man Therap. 2014 Dec 10;22(1):40

These results strongly suggest that chiropractic clinical researchers are not developing ICDs at a readability level congruent with the national average acceptable level. The low number of elements in some of the informed consent documents raises concern that not all research participants were fully informed when given the informed consent, and it may suggest that some documents may not be in compliance with federal requirements. Risk varies among institutions and even within institutions for the same intervention.

Feasibility of using a standardized patient encounter for training chiropractic students in tobacco cessation counseling.

Hawk C, Kaeser MA, Beavers DV.

J Chiropr Educ. 2013 Fall;27(2):135-40.

This active learning exercise appeared to be a feasible way to introduce tobacco counseling into the curriculum.

Consensus process to develop a best-practice document on the role of chiropractic care in health promotion, disease prevention, and wellness.

Hawk C, Schneider M, Evans MW Jr, Redwood D.

J Manipulative Physiol Ther. 2012 Sep;35(7):556-67

This living document provides a general framework for an evidence-based approach to chiropractic wellness care.

Chiropractic or osteopathic manipulation for children in the United States: an analysis of data from the 2007 National Health Interview Survey.

Ndetan H, Evans MW Jr, Hawk C, Walker C.

J Altern Complement Med. 2012 Apr;18(4):347-53.

C/OM is primarily used for back and neck pain, which is increasing in prevalence in children. Teens are more likely to use it than are younger children.

The role of chiropractic care in older adults.

Dougherty PE, Hawk C, Weiner DK, Gleberzon B, Andrew K, Killinger L.

Chiropr Man Therap. 2012 Feb 21;20(1):3.

Given the utilization of chiropractic services by the older adult, it is imperative that providers be familiar with the evidence for and the prudent use of different management strategies for older adults.

I am pleased to say that Prof Hawk gave me no problems at all; her case is clear: she is a champion of using research as a means for promoting chiropractic, has published many papers in this vein, clearly prefers the journals of chiropractic that nobody other than chiropractors ever access, and has an impeccable track record when it comes to avoiding negative conclusions which could harm chiropractic in any way.

Very well done indeed!

WELCOME, PROF HAWK, TO THE ‘ALT MED HALL OF FAME’.

 

You have to excuse me, if I keep coming back to this theme: so-called ‘alternative cancer cures’ are truly dangerous. I have tried to explain this already many times, for instance here, here and here. And it is by no means just alternative therapists who make a living of such quackery. Sadly qualified medical doctors are often involved as well. As to prove my point, here is a tragic story that broke yesterday:

Former Miss New Hampshire, Rachel Petz Dowd, lost her battle with cancer on Sunday 12 June 2016 — a battle she fought publicly through personal writings in a blog in hopes of helping others on a similar journey toward healing. The singer/songwriter and mother of three from Auburn died about a month after traveling to Mexico for an aggressive form of alternative cancer treatment. She turned 47 last week. Dowd was diagnosed with stage 2 triple negative breast cancer in May 2014. The diagnosis led her to create a blog called “Rachel’s Healing” to document what she hoped would be a journey back to health. “I hope my readers can gain something from my journey and that they find their own personal way to combat this disease impacting too many women today,” she wrote. Dowd used the blog to share her experiences with traditional and natural medicine during her cancer fight.

On 5/3/16 Mrs Dowd wrote on her blog: “Well after some careful consideration and looking at different clinics and hospitals we’ve made a decision. Will be going to the CMN Hospital on the Yuma, Arizona border*. For 28 days of treatments. It’s not a day clinic but a full hospital servicing over the past 30 years. There’s a special wing dedicated to alternative cancer care and the treatment list is impressive.  Many treatments that are not available in this country. We feel this would be the best course of care daily for 28 days and then at the end of the 4 weeks I intend my immune system to be back on-line. I will be doing a stem cell boost of my bone marrow the last week. I know of a women, Shannon Knight, from The Truth About Cancer documentary, who had stage 4 metastasized into locations of her bones and her lungs and she came out of there completely cured. Her oncologist said it was nothing short of a miracle, but she said no it was just clean hard work!  She said no it was just clean the hard, aggressive treatments that only attack cancer, boost and prime your immune system, become a whole, healthy being once again:) It is possible and I am planning on being one of the exceptions like Shannon!”

  • The hospital is across the US border in Mexico; it is run by medically qualified personnel.

The hospital [“CMN Hospital’s facility is only 14 blocks away once you cross the border to begin your alternative cancer treatment”] has a website where they tell a somewhat confusing story about their treatment plans; here is a short but telling excerpt:

CMN’s protocols are individualized and comprehensive. You will benefit from oxidative therapies, IV minerals selenium and bicarbonate IV vitamins such as vitamin B-17 and IV vitamin C. Far infrared and others including MAHT, Cold Laser Therapy, Hyperbaric Oxygen Therapy and Ozone Therapy are a daily part of your protocol. Ultraviolet Blood Irradiation is effective in destroying pathogens in your blood and slows the growth of cancer cell growth. CMN’s Stem cell therapy and Dendritic cell therapy are just two of the advanced cancer treatments applied to patients.”

And here is what they say about three therapies as examples of treatments that have discussed before on this blog: vitamin C, Laetrile and Essiac.

IV Vitamin C If large amounts of vitamin C are presented to cancer cells, large amounts will be absorbed. In these unusually large concentrations, the antioxidant vitamin C will start behaving as a pro-oxidant as it interacts with intracellular copper and iron. This chemical interaction produces small amounts of hydrogen peroxide. Because cancer cells are relatively low in an intracellular anti-oxidant enzyme called catalase, the high dose vitamin C induction of peroxide will continue to build up until it eventually lyses the cancer cell from the inside out!

IV Vitamin B17 / Laetrile Also known as amygdaline, Vitamin B-17 is a molecule made up of four parts: -2 parts Glucose -1 part Benzaldahyde-1 part Hydrogen Cyanide. Laetrile is found in at least 1200 different plants, including apricots, peaches, apple seeds, lentils, cashews, brown rice, millet, and alfalfa. Commercial preparations of laetrile are obtained from the kernels of apricots, peaches and bitter almonds. The body requires an enzyme called beta-glucosidase in order to process laetrile and release the cyanide. Studies have shown that cancer cells contain more of this enzyme than normal cells, which allows for a higher release of cyanide at tumor sites. Another enzyme known as rhodanese is important in this process. Normal healthy cells contain rhodanese which protects them from the activated cyanide. Most cancer cells are deficient in this enzyme, leaving them vulnerable to the poison. Tumor destruction begins once the cyanide is released within the malignancies, meaning laetrile therapy is selectively toxic to cancer cells while remaining non-toxic to normal cells.

Essiac Tea / Order Original Essiac Tea Essiac, given its name by Rene Caisse (“caisse” spelt backwards), consists of four main herbs that grow in the wilderness of Ontario, Canada. The original formula is believed to have its roots from the native Canadian Ojibway Indians. The four main herbs that make up Essiac are Burdock Root, Slippery Elm Inner Bark, Sheep Sorrel and Indian Rhubarb Root. Essiac tea helps release toxins that build up in fat and tissues into the blood stream where they can be filtered and excreted by the liver and kidneys.  Cleaning the body of toxins and impurities frees up the immune system to focus on killing cancer cells and protecting the body.

 

I think I will abstain from further comments, firstly because I want to avoid getting sued by these people and secondly because it seems all too depressingly obvious.

Seasonal allergic rhinitis (hay fever) is a common condition which can considerably reduce the quality of life of sufferers. Homeopathy is often advocated – but does it work?

A new study was meant to be an “assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting.”

The investigator performed a ‘clinical observational study’ of eight patients from his private practice using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and 4 weeks of individualized homeopathic treatment which was given as an add-on to conventional treatments.

The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and 4 weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; P<0.001) and 1.06 (SD, 0.25; P<0.001) respectively.

The author concluded as follows: Individualized homeopathic treatment was associated with significant alleviation of hay fever symptoms, enabling the reduction in use of conventional treatment. The results presented in this study can be considered as a step towards a pilot pragmatic study that would use more robust outcome measures and include a larger number of patients prescribed a single or a multiple homeopathic prescription on an individualized basis.

It is hard to name the things that are most offensively wrong here; the choice is too large. Let me just list three points:

  • The study design is not matched to the research question.
  • The implication that homeopathy had anything to do with the observed outcome is unwarranted.
  • The conclusion that the results might lend themselves to develop a pilot study is meaningless.

The question whether homeopathy is an effective therapy for hay fever has been tested before, even in RCTs. It seems therefore mysterious why one needs to revert to tiny observational studies in order to plan a pilot, and even less for an assessment of effectiveness.

There are few conditions which are more time-dependent than hay fever. Any attempt of testing the effectiveness of medical interventions without a control group seems therefore not just questionable but wasteful. Clinical studies absorb resources; even if the author was happy to waste his time, he should not assume that he can freely waste the time, effort and availability of his patients.

Two final points, if I may:

  • An observational study of homeopathy for hay-fever without a control group might be utterly useless but it is still an investigation that requires certain things. As far as I can see, this study did not even have ethics approval nor is there a mention of informed consent. Strictly speaking, this makes it an unethical study.
  • If we allow research of this nature to take place and be published, we give clinical research a bad name and undermine the confidence of the public in science.

I am puzzled how such a paper could pass peer review and how an Elsevier journal could even consider publishing it.

The question whether pharmacists should sell unproven alternative medicines will not go away. On this blog, we have discussed it repeatedly, for instance here, here and here. The Australian Journal of Pharmacy’s latest poll shows that readers have their suspicions about the validity of naturopathic medicines, with a whopping 544 voters choosing the option, “No, there’s no evidence they work” at the time of writing.

This constitutes 65% of readers who took part in the poll. A significant minority – 193 readers, with 23% of the vote – said that pharmacies should stock these medicines as they are legitimate products. Five per cent said that while they questioned their efficacy, pharmacy should stock them; and 3% said they were unsure, but the public wanted them.

Taree pharmacist and member of Friends in Science and Medicine Ian Carr, who has spoken to the AJP several times in the last couple of weeks as debate has continued about the subject of naturopathy in pharmacy, said he was surprised and pleased at the strength of the No vote. “I looked at [the poll] on the first day, and there was definitely a majority saying these things have no evidence, but there was still above 30% saying yes, they were legitimate products,” Carr told the AJP. “That’s been dwarfed by a lot of people who’ve looked in, and it’s interesting to have that many people vote. “I’m glad that it seems to be becoming recognised that there’s a need for the evidence base in these things, and the difference between having a naturopathic product or supplement on the shelf, and having somebody there charging for their time, as a naturopath, dispensing advice without knowing the patient’s background and without an intervention by a registered pharmacist.” He encouraged pharmacists concerned about the validity of naturopathy to consider what products and services they offer.

Where naturopaths are used, they should at least be expected to keep a record of products and advice dispensed, he says, similar to protocols around blood pressure and blood glucose monitoring. “If there’s going to be an insistence that naturopaths remain, that’s the way I’d like to see it: that the pharmacy has good records and oversight of what they’re doing. I think, given our connection to the PBS and the fact that we as pharmacists are looking for a more serious role as part of the health care team generally, and having a more active and integrative role, we would be silly to fritter it away on peripheries like naturopathy. I personally see the opportunities in evidence-based medicine and what flows from that, rather than trying to make up dollars. We’re more likely to lose control of pharmacy if we don’t guard it jealousy.”

One of the suppliers of CAM products to pharmacies responded to the article by stating the following:

“The complementary and alternative medicine (CAMs) sector and its role in healthcare management continues to be hotly debated by the media. Rather than dissuade this debate, we actively encourage this discussion, as it shines a light on many issues which need to be addressed. Of priority is the point that not all complementary and alternative medicine products are equal. As in many media articles, an incredibly wide spectrum of products are grouped under the label of ‘CAMs’. Products with specific clinical evidence, high-quality manufacturing processes and transparency on the sourcing of ingredients are not clearly identified from products without these qualities. Consumers and healthcare professionals are unable to distinguish this difference due to a lack of clear labelling. We agree with calls for CAMs products to be more thoroughly assessed, beyond being simply classified as ‘safe’. Healthcare professionals and consumers deserve this information and are indeed asking for it. Consumers are aware of the impact of their choices and that their demand drives industry change. History is littered with recent examples where consumer awareness has changed the marketplace for the better. Consumer-driven change in the CAMs industry IS possible, it just needs to be supported. The Australian CAMs industry needs to increase healthcare professional and consumer education on the importance of evidence-based CAM products; on what ‘evidence-based’ means and what this difference delivers… Healthcare professionals are key to helping their patients understand that not all CAMs or natural medicine products are equal… It takes time to change the way people see CAMs and natural medicines – but it is of inherent value for the consumer. Something, we believe, is integral to the future of the industry.”

The arguments are clearest, if we focus on a specific type of alternative medicine and spell out what precisely we are talking about. The one that comes to mind is, of course, homeopathy. In my view, there is no good reason why pharmacists should sell homeopathic remedies. It is comforting to know that the Chief Scientist of the UK Royal Pharmaceutical Society, Professor Jayne Lawrence, agrees; she stated about a year ago that “the public have a right to expect pharmacists and other health professionals to be open and honest about the effectiveness and limitations of treatments. Surely it is now the time for pharmacists to cast homeopathy from the shelves and focus on scientifically based treatments backed by clear clinical evidence.”

And what has changed since?

Nothing, as far as I can see – but please correct me, if I am wrong.

I think it is important that we remind the community pharmacists everywhere that they have their very own codes of ethics and that they need to adhere to them. If they don’t, they tacitly agree that they are not really healthcare professionals but mere shop-keepers.

We tend to trust charities; many of us donate to charities; we think highly of the work they do and the advice they issue. And why shouldn’t we? After all, a ‘charity’ is ‘an institution or organization set up to provide help, money, etc, to those in need’. Not a hint at anything remotely sinister here – charities are good!

Except, of course, those that are not so good!

By ‘not so good’ I mean charities that misinform the public to a point where they might even endanger our health, well-being and savings. Yes, I am speaking of those charities that promote unproven or disproven alternative therapies – and unfortunately, there are many of those around today.

Our recent letter in the SUNDAY TIMES, tried to alert the public to this problem and to the fact that the UK regulator seems to be failing to do much about it. A Charity Commission spokesman, in turn, replied that his organisation had received the letter and would respond formally to it:

“The Commission is required to register organisations as charities which are established for exclusively charitable purposes for the public benefit,” he said. “Charitable purposes for the advancement of health include conventional methods as well as complementary, alternative or holistic methods which are concerned with healing mind, body and spirit in the alleviation of symptoms and the cure of illness. Those organisations dealing with complementary and alternative medicines must be able to demonstrate that they are capable of promoting health otherwise they will not be for the public benefit.

“The Commission is the registrar and regulator of charities however it is not the authority in the efficacy of any and every non-traditional medical treatment. These are issues of substantial debate with a variety of opinions. Each case is considered on its merits based on the evidence available. To be charitable there needs to be sufficient evidence of the efficacy of the method to be used. The Commission must further be assured that any potential harm that might be said to arise does not outweigh the benefit identified by the method.

“The Commission expects charities to provide information that is factually accurate with legitimate evidence.” 

But is the information provided by all charities factually accurate?

Take, for instance, YES TO LIFE! Have a good look and then decide for yourself.

On their website they state: “We provide support, information and financial assistance to those with cancer seeking to pursue approaches that are currently unavailable on the NHS. We also run a series of educational seminars and workshops which are aimed at the general public who want to know more and practitioners working with people who have cancer.”

The website informs us about many alternative therapies and directly or indirectly promote them for the curative or supportive treatment of cancer. I have chosen 5 of them and copied the respective summaries as published by YES TO LIFE. My main selection criterion was having done some research myself on the modality in question. Here are the 5 cancer treatments which I selected; the text from YES TO LIFE is in bold, and that of my published research is in normal print with a link to the published paper:

CARCTOL

Carctol is a relatively inexpensive product, specifically formulated to assist cells with damaged respiration, it is also a powerful antioxidant that targets free radicals, the cause of much cellular damage. It also acts to detoxify the system.

The claim that Carctol is of any benefit to cancer patients is not supported by scientific evidence.

LAETRILE

Often given intravenously as part of a programme of Metabolic Therapy, Laetrile is a non-toxic extract of apricot kernels. The claimed mechanism of action that is broken down by enzymes found in cancer cells. Hydrogen cyanide, one of the products of this reaction then has a local toxic effect on the cells.

The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. The risk-benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative.

MISTLETOE

Mistletoe therapy was developed as an adjunct to cancer treatment in Switzerland in 1917-20, in the collaboration between Dr I Wegman MD and Dr Rudolf Steiner PhD (1861-1925). Mistletoe extracts are typically administered by subcutaneous injection, often over many years. Mistletoe treatment improves quality of life, supports patients during recommended conventional cancer treatments and some studies show survival benefit. It is safe and has no adverse interactions with conventional cancer treatments.

None of the methodologically stronger trials exhibited efficacy in terms of quality of life, survival or other outcome measures. Rigorous trials of mistletoe extracts fail to demonstrate efficacy of this therapy.

UKRAIN

A type of low toxicity chemotherapy derived from a combination of two known cytotoxic drugs that are of little use individually, as the doses required for effective anticancer action are too high to be tolerated. However the combination is effective at far lower doses, with few side effects.

The data from randomised clinical trials suggest Ukrain to have potential as an anticancer drug. However, numerous caveats prevent a positive conclusion, and independent rigorous studies are urgently needed. [To judge the validity of this last treatment, I also recommend reading a previous post of mine.]

Finally, it might be informative to see who the individuals behind YES TO LIFE are. I invite you to have a look at their list of medical advisors which, I think, speaks for itself. It includes, for instance, Dr Michael Dixon of whom we have heard before on this blog, for instance, here, here and here.

Say no more!
