Mistletoe, an anthroposophical medicine, is often recommended as a so-callled alternative medicine (SCAM) for cancer patients. But what type of cancer, what type of mistletoe preparation, what dosage regimen, what form of application?

The aim of this systematic analysis was to assess the concept of mistletoe treatment in published clinical studies with respect to indication, type of mistletoe preparation, treatment schedule, aim of treatment, and assessment of treatment results. The following databases were systematically searched: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, CINAHL, and “Science Citation Index Expanded” (Web of Science). The researchers assessed all studies for study types, methods, endpoints and mistletoe preparations including their ways of application, host trees and dosage schedules.

The searches revealed 3296 hits. Of these, 102 publications with a total of 19.441 patients were included. The researchers included several study types investigating the application of mistletoe in different groups of participants: cancer patients with any type of cancer were included as well as studies conducted with healthy volunteers and pediatric patients. The most common types of cancer were:

  • breast cancer,
  • pancreatic cancer,
  • colorectal cancer,
  • malignant melanoma.

Randomized controlled studies, cohort studies and case reports make up most of the included studies. A huge variety was observed concerning the type and composition of mistletoe extracts (differing pharmaceutical companies and host trees), ways of applications and dosage schedules. Administration varied widely, e. g. between using mistletoe extract as sole treatment and as concomitant therapy to cancer treatment. The researchers found no relationship between the mistletoe preparation used, host tree, dosage, and cancer type.

A variety of different mistletoe preparations was used to treat cancer patients. Due to the heterogeneity of the mistletoe preparations used, no comparability between different studies or within single studies using different types of mistletoe preparations or host trees is possible. Moreover, no relationship between mistletoe preparation and type of cancer can be observed. This results in a severely limited comparability of studies with regard to the different cancer entities and mistletoe therapy in oncology in general. Analyzing the methods sections of all articles, there are no information on how the selection of the respective mistletoe preparation took place. None of the articles provided any argument which type of preparation (homeopathic, anthroposophic, standardized) or which host tree was chosen due to which selection criteria. Considering preparations from different companies, funding may have been the reason of the selection.

Dosage or dosage regimens varied strongly in the studies. Due to the heterogeneity of dosage and dosage regimens within studies and between studies of the endpoints the comparability of the different studies is severely limited. Duration of mistletoe treatment varied strongly in the studies ranging from a single dose given on one day to the application of mistletoe preparations for several years. Moreover, the duration of treatment frequently varied within the studies. Mistletoe preparations were administered by different ways of application. Most frequently, the patients received mistletoe preparations subcutaneously. The second most common way was intravenous administration of mistletoe preparations. According to the respective manufacturers, this type of application is only recommended for Lektinol® and Eurixor®. Other preparations were given as off-label intravenous applications. No dosage recommendations from the respective manufacturers were available. Only in two studies the dose schedules were mentioned: according to the classical phase I 3 + 3 dose escalation schedule or in ratio to the body surface area.

The authors concluded that despite a large number of clinical studies and reports, there is a complete lack of transparently reported, structured procedures considering all fields of mistletoe therapy. This applies to type of mistletoe extract, host tree, preparation, treatment schedules as well as indication with respect of type of cancer and the respective treatment aim. All in all, despite several decades of clinical mistletoe research, no clear concept of usage is discernible and, from an evidence-based point of view, there are serious concerns on the scientific base of this part of anthroposophical treatment.

A long time ago, I worked as a junior doctor in a hospital where we used subcutaneous misteloe injections regularly to treat cancer. I remember being utterly confused: none of my peers was able to explain to me what preparation to use and how to does it. There simply were no rules and the manufacurer’s instructions made little sense. I suspected then that mistletoe therapy was a danerous nonsense. Today, after much research has been published on mistletoe, I do no longer suspect it, I know it.

I would urge every cancer patient to stay well clear of mistletoe and those practitioners who recommend it.

Recently, I had the pleasure to give a lecture about bias in research to medical students at my former medical school in Vienna. This led to interesting discussions with the audience. They prompted me to think more than usual about ‘the biased researcher’, a phenomenon that, in my opinion, seriously plagues the field of so-called alternative medicine (SCAM). The way I see it, we can differentiate 4 overlapping categories of researchers (male or female; for simplicity, I here use only the masculine form) investigating the effectiveness of various forms of SCAM:

THE TRUE SCIENTIST

The true scientist is adequaately trained in all aspects of his work. Therefore, he knows that he research consists of testing hypotheses. He does his job without emotional or ideological baggage. All he aims at doing is answering the research question at hand in the most rigorous fashion. He is not influenced by outside pressures, does not care about the direction of his results, and merely wants to conduct the best science possible that his particular situation allows. In other words, he does what he can to minimize all sources of bias.

THE SLOPPY RESEARCHER

The sloppy researcher is either less well trained or he is less focussed and somewhat careless. He tends to cut corners, and is thus prone to make mistakes. His miskakes can introduce bias in his research which is unintentional because he has no axe to grind. In other words, the sloppy researcher is not biased but might easily produce biased results. As the sloppyness is unintentional, the resulting bias can go in either direction; the sloppy researcher might therefore generate false-positive and false-negative findings at random.

THE BIASED RESEARCHER

The biased researcher does have an axe to grind. Typically, he has a strong positive opinion about the treatment he is testing. For him, the concept of falsifying his beloved hypothesis is an abomination – he might know that this is how science out to work, but he can simply not bring himself to doing it. His mission is to confirm his prior conviction that the therapy in question is effective. This conviction is so strong that he does not feel that he is doing anything wrong. Obviously, the biased researcher would introduce bias into his research at multible levels. His bias will then compell him to hide the flaws in his research as much as he can. Consequently, his published papers will not easily disclose his bias and will therefore have the power to mislead the public.

THE DISHONEST RESEARCHER

The dishonest researcher is out to cheat. He wants to generate resuts of a certain type, usually showing that the therapy in question is effective. He is usually motivated by money and/or ambition. He may be sufficiently well trained to be able to hide his dishonesty from detection. Like the biased researcher’s papers, his fraudulent publications will not disclose his fabrications and will therefore have the power to mislead the public.

You will, of course, realize that, in my attempt to create these 4 categories, I have exaggerated and created caricatures of the real-life situations. However, I feel the the distinction between the 4 categories might be helpful to understand medical research and its pitfalls. As I pointed out in the introduction, the categories overlap. In reality, most researchers are hybrids of two or more categories. For instance, nobody can entirely be free of bias and everybody makes mistakes occasionally.

The question arises as to which type of category might dominate SCAM. I am not aware of reliable research that would answer it. However, my experience tells me that, in SCAM, we have a regrettable void of true scientists combined with an abundance of biased researchers (see, for instance, the growing list of researchers in my ALTERNATIVE MEDICINE HALL OF FAME). What is worse, the latter category is bringing SCAM research more and more into disrepute which, in turn, demotivates true scientists to consider SCAM as a serious subject.

I should warn you, this is a somewhat unusual post.
Yesterday, I had a debate with someone in the comments section of a 10 year old post about Reiki. First I thought it might be interesting, then I realized that it was not a debate at all but that I was entertaining a troll. I usually stop at that point – yet, in this case, I carried on to see when he [I assume it was a male person] would stop.
The amazing thing was, he never did!
He kept on going and going and going. Eventually, I cut him off by no longer posting his attempts to provoke me. After that plenty more of his comments arrived which I then deleted.
Despite the fact that the exchange is only mildly amusing, I thought I copy the last bits of it. What comes out quite clearly, I hope, is the way a troll tries to gradually rope you in. Perhaps it prevents someone to fall victim of a troll.
It all started with me stating: “What will I call a billion people who believe in something absurd? I WOULD CALL THEM SERIOUSLY MISLED AND PERHAPS EVEN STUPID”. At first, others were involved but by the 24th it was between me and the troll.

Here we go, enjoy!

More than a billion humans know and believe that the cow is “Kamadhenu” or God. One can be called a stupid, and two can be called a moron, but what will call you when a billion people believe in something? How about calling all the Indians that believe in the cow as god “Arrogant”? Will that cut it?
I might be arrogant, and i am ok with it. But you are dishonest and contradictory. I would rather be with an arrogant person than a dishonest, ridiculous, or contradicing person. Because I know the dishonest, ridiculous, and contradicting person will cause me more harm than this so-called “arrogant” person. There, I sent you away. Go home and come back tomorrow with a better argument that sounds morally good!

what will I call a billion people who believe in something absurd?
I WOULD CALL THEM SERIOUSLY MISLED AND PERHAPS EVEN STUPID

More than a billion humans know and believe that the cow is “Kamadhenu” or God.

To more than 6 billion people (i.e. rest of the world), cow is NOT god. In fact, a lot of them want to see it served on a plate. If we were to take a vote w.r.t cow’s godliness, it looses sorely.

You are not arrogant, you are plain stupid.

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 13:48 (Edit)

The arrogancy is not mine, it is the Westerners. I was actually supporting the statement that Reiki is not plausible by giving an example from India in which Hindus (there is a billion of them) “know” that the cow is a god. Does it mean that the cow is a god? You folks are very arrogant and no body can save you. Your civilization will definitely be the first one to be doomed. As for the others are concerned, it becomes a blessing that they do not have a civilization

Even at the time of death healing can help the dying person to ease the transition from this world to the next. Should one not be well versed in spiritual matters it can come as a bit of a shock to realise that one is no longer in a physical body.

Death, of the body, is not the end. Life goes on in another dimension. The ´dead´ miss us as much as we miss them. Imagine two big bubbles. You are in one and your loved one is in the other. You cannot touch each other and the bubbles are floating off further and further in different directions. There are a couple of ways in which you can communicate. You can take up telepathy or you can see a medium.

Marvellous!

Only one other dimension? So we become straight lines with ni width or thickness?

Oh, in that dimension, thickness knows no bounds.

So it would appear!

@Ralph William Maver

You are an arrogant person.

Are you certain that you selected the right personal pronoun in this sentence?

I know that Reiki works.

Ah, you must be one of those persons who spent $4000 on a Reiki Level 4 Master Course (or whatever it is called), and are now trying their very best to protect and possibly recoup their investment.

You are one of those people who challenge what they don’t understand.

Sorry to tell you, but you are the one who fails to understand that ‘Reiki’ and all that other bogus ‘energy medicine’ stuff is just a con trick, a way to separate gullible people from their money.

Then again, having taken a look around your Web site, it may well be that you have been the one who was conned first, and are in turn now trying to trick other people – although not very successfully, by the looks of it. I almost feel sorry for you.

My bit of advice: go find another, more honest occupation. This reiki stuff doesn’t work for you. And oh, get a better Web designer.

I don’t have a soul.

Unless we count the Otis Redding, Aretha Franklin, Marvin Gaye, Curtis Mayfield and all albums…

Next?

I said more than a billion people believe that the cow is god, and instead of reading the rest of the statement, you people, including Edzrad, jumped on me and started calling me names, if only you read the rest of my statement, you would know that I don’t believe in Reiki. But then you revealed your true colours. Truth always goes in hand with compassion, which I guess you do not have. You failed to recognize the racism in your own comment by calling 1 billion people (Hindus) stupid. It is not the stupid people that are destroying the world, but cruelty is spread by the in-compassionate fools. Now go, respond by doing a line-by-line grammar check of my statement. If civilization falls, yours will be the first to fall.

Edzrad, jumped on me and started calling me names”
TEMPTING! BUT I DIDN’T
Now try to spell my name correctly, if you don’t mind.

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 15:45 (Edit)

Your life and existence must be in this thread, so pathetic.

I intentionally misspelt your name expecting to reveal the “ego” component in your statements.
Do you really think a misspelling in your name is so significant? No wonder your country is a philosophical mess, caught in between two ideologies. My concern is that people with your attitude are destroying the rest of the world, like that guy in 1853, American Commodore Matthew Perry who forcefully opened Japan for trade. Not only are you arrogant, but you are also blind. May demise to your civilization come soon.

“Do you really think a misspelling in your name is so significant?”
No, and I did not claim it to be.

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 17:11 (Edit)

I am really not interested in this conversation anymore, yes, it does seem that you are ‘awfully triggered’ and conversing with me. because the replies are almost an instantaneous basis, like the insecure Donald Trump tweeting. “…Now try to spell my name correctly, if you don’t mind.” These are your words, and you now say that you really did not mean it. I am just getting tired as if I am giving directions to a blind and deaf person. I just came to your thread because as a massage therapy student, 8 years ago, I was having an argument with my students and lecturer that non-evidence based therapies should not be promoted aggressively, but with a note and disclaimer because the public are being taken advantage by scamsters providing sham treatment. Now all those things are lost but we are now in a different territory, I was giving the one million Hindu and cow example to demonstrate that sometimes things does not matter, but it has to be handled more in a human way. It seems that you do not have that big heart or genroisty, but instead it seems that you keep this thread live just for fun. And the more time passes, the more small you become in your replies, I am not sure maybe you died and it is your grandson that is maintaining this blog, who knows? Go to hell, do whatever you want. If you want a closure, please block me.

“I am really not interested in this conversation anymore”
By contrast, I never was!
It is you who foisted it on me.

I understand your need to feel good about your actions. I have a bigger heart than you. Hence, I am sorry.
bye bye

To be specific, I am an RMT, and I don’t believe in Reiki, but that does not mean that we go around insulting people. Why? Because it is not necessary. Only two types of people do unnecessary things (a) fools, and (b) malicious people. How do we know that you are not some sort of psycho living a pathetic life, and you are taking this opportunity to ‘bash’ people, in the name of reason and objectivity? Do you want us to trust you? You just put one billion people beneath by calling them stupid (and the other commenter who would rather see a cow on a plate, how insensitive that comment is? No wonder people hate America and Americans) Initially I thought you were arrogant. I take it back, because I think you are simply malicious (and maybe half your country)…one billion Hindus are stupid? (I gave that as a metaphor, I was born a Hindu, but I am not an hindu, now)

” I am an RMT”

Yeah, I am a railroad worker, and I am from the UK. These things make you appear so petty.

“we go around insulting people”

When and how did I insult you?

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 17:14 (Edit)

That is why I said you are blind, and that is why I said that you must belong to a particular demographic. As I said, I am not interested in conversing anymore. I am more honest than you and made my intentions clear. You need not block or moderate me, But there is no point in coming back to this thread.

thanks for that!

The English have the power of speech and the tool of articulation. Using this, they conquer all the world without doing all the hard work or shedding blood, but don’t worry, justice may be late, but it will rule one day, what was got by simply using the tongue, will also be lost using the same tongue. In the end, they will be the most pathetic souls among all life forms:

Edzard on Sunday 15 January 2023 at 08:39
what will I call a billion people who believe in something absurd?
I WOULD CALL THEM SERIOUSLY MISLED AND PERHAPS EVEN STUPID

oh, I see: you think I’m English!

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 17:28 (Edit)

“oh, I see: you think I’m English!”
That was supposed to be an insult, I don’t really care who you are. I don’t care even if I am wrong. You should know that I am not making an effort to know you. I can google you in five minutes, but you are not worth my time. All I know is that you are a troublemaker (Like Donald Trump) who lives just for the fun of it. Trump uses certain things to disguise is contempt and selfishness, you are just using the war against alternative medicine to shield your general malice. You are not a good person, that I know. And I am sure that nobody would have told you that — greatest insult.

Troll: a person who antagonizes (others) online by deliberately posting inflammatory, irrelevant, or offensive comments or other disruptive content

I may be a troll, but you are simply an abuser and maipulator of knowledge, power, and position. At best, I would have annoyed a few people. But you just called one billion people stupid, then guess what your real intentions might be? You have more power to damage the world then me, If I am a troll, you are simply a evil person

I have no intention to delete this comic relief!

Like I said, tongue they use to unleash their malice, by the tongue their souls will die a pathetic death

a characteristic of a troll is that he/she cannot quit easily

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 17:47 (Edit)

That’s right, senile, sadist, probably news does not excite you, so come back and read the comments to feel that you are indeed alive. So pathetic. Bye — If you really think I am a troll, then you probably should not reply, every internet user knows this. But if you are intentionally engaging with a troll, then it means that there is something wrong with you greater than that troll. Like I said, I might be a a troll, but you are even greater than that — an evil person (because you have power, position, influence) — don’t…

It’s not that I think you are a TROLL, you have proven it to us.

Sivalingam (Siva) Canjeevaram on Tuesday 24 October 2023 at 17:44 (Edit)

If you can call one billion Hindus stupid. I should not mind for you calling me a troll.
And this time, I am deciding to quit. What a bore!

___________________________________________

Re-reading this today, I am still amazed at the mindset of my troll. Perhaps I should by now have got used to it – after all, this sort of thing does happen regularly on this blog. The lesson, I think, is not to let it happen and tell the troll early on to go yonder and multiply.

 

 

Robert Jütte, a German medical historian, has long been a defender of homeopathy and other forms of so-called alternative medicine (SCAM). His latest paper refers to the situation in Switzerland where the public was given the chance to vote for or against the reimbursement of several SCAMs, including homeopathy. I reported previously about this unusual situation, e.g.:

Unsurprisingly, Prof Jütte’s views are quite different from mine. Here is the abstract of his recent paper:

Behind the principle of involving users and voters directly in decision-making about the health care system are ideas relating to empowerment. This implies a challenge to the traditional view that scientific knowledge is generally believed to be of higher value than tried and tested experience, as it is the case with CAM. The aim of this review is to show how a perspective of the history of medicine and science as well as direct democracy mechanisms such as stipulated in the Swiss constitution can be used to achieve the acceptance of CAM in a modern medical health care system. A public health care system financed by levies from the population should also reflect the widely documented desire in the population for medical pluralism (provided that therapeutical alternatives are not risky). Otherwise, the problem of social inequality arises because only people with a good financial background can afford this medicine.

I think that Jütte’s statement that “a public health care system financed by levies from the population should also reflect the widely documented desire in the population for medical pluralism provided that therapeutical alternatives are not risky. Otherwise, the problem of social inequality arises because only people with a good financial background can afford this medicine” is untenable. Here are my reasons:

  • Lay people are not normally sufficiently informed to decide which treatments are effective and which are not. If we leave these decisions to the public, we will end up with all manner of nonsense diluting the effectiveness of our health services and wasting our scarce public funds.
  • Jütte seems to assume that SCAMs that are not risky do no harm. He fails to consider that ineffective treatments inevitably do harm by not adequately treating symptoms and diseases. In serious conditions this will even hasten the death of patients!
  • Jütte seems concerned about inequity, yet I think this concern is misplaced. Not paying from the public purse for nonsensical therapies is hardly a disadvantage. Arguably, those who cannot affort ineffective SCAMs are even likely to benefit in terms of their health.

I do realize that there might be conflicting ethical principles at play here. I am, however, convinced that the ethical concern of doing more good than harm to as many consumers as possible is best realized by implementing the principles of evidence-based medicine. Or – to put it bluntly – a healthcare system is not a supermarket where consumers can pick and chose any rubbish they fancy.

I wonder who you think is correct, Jütte or I?

Although bullshit is common in everyday life and has attracted attention from philosophers, its reception (critical or ingenuous) has not, to our knowledge, been subject to empirical investigation. Pseudo-profound bullshit consists of seemingly impressive assertions that are presented as true and meaningful but are actually vacuous.

In this study, researchers presented participants with bullshit statements consisting of buzzwords randomly organized into statements with syntactic structure but no discernible meaning (e.g., “Wholeness quiets infinite phenomena”). Across multiple studies, the propensity to judge bullshit statements as profound was associated with a variety of conceptually relevant variables (e.g., intuitive cognitive style, supernatural belief). Parallel associations were less evident among profundity judgments for more conventionally profound (e.g., “A wet person does not fear the rain”) or mundane (e.g., “Newborn babies require constant attention”) statements.

The authors concluded that these results support the idea that some people are more receptive to this type of bullshit and that detecting it is not merely a matter of indiscriminate skepticism but rather a discernment of deceptive vagueness in otherwise impressive sounding claims. Our results also suggest that a bias toward accepting statements as true may be an important component of pseudo-profound bullshit receptivity.

Harry G Frankfurt published his delightful booklet ‘ON BULLSHIT‘ in 2005. Since then, the term ‘bullshit’ has become accepted terminology in philosophy and science. But what exactly is bullshit? Frankfurt explains that is something between a lie and a bluff, perhaps more like the latter than the former.

In another recent article, Fugelsang explains that the growing prevalence of misleading information (i.e., bullshit) in society carries with it an increased need to understand the processes underlying many people’s susceptibility to falling for it. He also reports two studies (N = 412) examining the associations between one’s ability to detect pseudo-profound bullshit, confidence in one’s bullshit detection abilities, and the metacognitive experience of evaluating potentially misleading information.

The results suggest that people with the lowest (highest) bullshit detection performance overestimate (underestimate) their detection abilities and overplace (underplace) those abilities when compared to others. Additionally, people reported using both intuitive and reflective thinking processes when evaluating misleading information. Taken together, these results show that both highly bullshit-receptive and highly bullshit-resistant people are largely unaware of the extent to which they can detect bullshit and that traditional miserly processing explanations of receptivity to misleading information may be insufficient to fully account for these effects.

I am sure that some of the discussions on this blog are excellent examples for people with low bullshit detection performance overestimating their detection abilities and overplacing those abilities.

This review evaluated the magnitude of the placebo response of sham acupuncture in trials of acupuncture for nonspecific LBP, and assessed whether different types of sham acupuncture are associated with different responses. Four databases including PubMed, EMBASE, MEDLINE, and the Cochrane Library were searched through April 15, 2023, and randomized controlled trials (RCTs) were included if they randomized patients with LBP to receive acupuncture or sham acupuncture intervention. The main outcomes included the placebo response in pain intensity, back-specific function and quality of life. Placebo response was defined as the change in these outcome measures from baseline to the end of treatment. Random-effects models were used to synthesize the results, standardized mean differences (SMDs, Hedges’g) were applied to estimate the effect size.

A total of 18 RCTs with 3,321 patients were included. Sham acupuncture showed a noteworthy pooled placebo response in pain intensity in patients with LBP [SMD −1.43, 95% confidence interval (CI) −1.95 to −0.91, I2=89%]. A significant placebo response was also shown in back-specific functional status (SMD −0.49, 95% CI −0.70 to −0.29, I2=73%), but not in quality of life (SMD 0.34, 95% CI −0.20 to 0.88, I2=84%). Trials in which the sham acupuncture penetrated the skin or performed with regular needles had a significantly higher placebo response in pain intensity reduction, but other factors such as the location of sham acupuncture did not have a significant impact on the placebo response.

The authors concluded that sham acupuncture is associated with a large placebo response in pain intensity among patients with LBP. Researchers should also be aware that the types of sham acupuncture applied may potentially impact the evaluation of the efficacy of acupuncture. Nonetheless, considering the nature of placebo response, the effect of other contextual factors cannot be ruled out in this study.

As the authors stated in their conclusion: the effect of other contextual factors cannot be ruled out. I would go much further and say that the outcomes noted here are mostly due to effects other than placebo. Obvious candidates are:

  • regression towards the mean;
  • natural history of the condition;
  • success of patient blinding;
  • social desirability.

To define the placebo effect in acupuncture trials as the change in the outcome measures from baseline to the end of treatment – as the authors of the review do – is not just naive, it is plainly wrong. I would not be surprised, if different sham acupuncture treatments have different effects. To me this would be an expected, plausible finding. But such differences just cannot be estimated in the way the authors suggest. For that, we would need an RCT in which patients are randomized to be treated in the same setting with a range of different types of sham acupuncture. The results of such a study might be revealing but I doubt that many ethics committees would be happy to grant their approval for it.

In the absence of such data, the best we can do is to design trials such that the verum is tested against a credible placebo which, for patients, is indistinguishable from the verum, while demonstrating that blinding is successful.

The ‘University College of Osteopathy’ announced a proposal to merge with the AECC University College (AECC UC).  Both institutions will seek to bring together the two specialist providers to offer a “unique inter-disciplinary environment for education, clinical practice and research in osteopathy, chiropractic, and across a wide range of allied health and related disciplines”.

The partnership is allegedly set to unlock significant opportunities for growth and development by bringing together the two specialist institutions’ expertise and resources across two locations – in Dorset and central London.

As a joint statement, Chair of the Board of Governors at AECC UC, Jeni Bremner and Chair of the Board of Governors at UCO, Professor Jo Price commented:

“We believe the proposed merger would further the institutional ambitions for both of our organisations and the related professional groups, by allowing us to expand our educational offering, grow student numbers and provide a unique inter-disciplinary training environment, providing students the opportunity to be immersed in multi-professional practice and research, with exposure to and participation in multi-disciplinary teams.

“There is also an exciting and compelling opportunity to expedite the development of a nationally unique, and internationally-leading MSK Centre of Excellence for Education and Research, developed and delivered across our two sites.”

The announcement is accompanied by further uncritical and promotional language:

Established as the first chiropractic training provider in Europe, AECC UC has been at the forefront of evidence-based chiropractic education, practice and research for more than 50 years. The institution is on an exciting journey of growth and development, having expanded and diversified its academic portfolio and activity beyond its traditional core offering of chiropractic across a broad range of allied health courses and apprenticeships, working closely with NHS, local authority and other system partners across Dorset and the south-west. The proposed merger with UCO would allow AECC UC to enhance the breadth and depth of its offer to support the expansion and development of the health and care workforce across a wider range of partners.

Now in its 106th year, UCO is one of the UK’s leading providers of osteopathic education and research with an established reputation for creating highly-skilled, evidence-informed graduates. UCO research is recognised as world-leading, delivering value to the osteopathic and wider health care community.

Sharon Potter, Acting Vice-Chancellor of UCO, said:

“As an institution that has long been at the forefront of osteopathic education and research, we are committed to ensuring further growth and development of the osteopathic profession.

“UCO has been proactively considering options to future-proof the institution. Following a review of strategic options, UCO is delighted by the proposed merger, working closely with AECC UC to ensure that UCO and osteopathy thrives as part of the inter-professional health sciences landscape, both academically and clinically. There is significant congruence between UCO and AECC UC in our strong aligned values, commitment to and delivery of excellent osteopathic education, clinical care and research, and opinion leadership.

“AECC UC has a strong track record of respecting the differences in professions, evidenced by the autonomy across the 10 different professional groups supported by the institution. The merger will not only mean we are protecting UCO through preserving its osteopathic heritage and creating a sustainable future, but that our staff and students can collaborate with other professional groups such as physiotherapy, chiropractic, sport rehabilitation, podiatry and diagnostic imaging, in a multidisciplinary MSK and rehabilitation environment unlike anywhere else in the UK.”

Professor Lesley Haig, Vice-Chancellor of AECC UC, commented:

“Preserving the heritage of UCO and safeguarding its future status as the flagship osteopathy training provider in the UK will be critical, just as it has been to protect the chiropractic heritage of the AECC brand. UCO is seen as synonymous with, and reflective of, the success of the osteopathy profession and we fully recognise and respect the important role that UCO plays not only as a sector-leading provider of osteopathic education, research and clinical care, but as the UK’s flagship osteopathy educational provider.

“Overall it is clear that UCO and AECC UC already have a common values base, similar understanding of approaches to academic and clinical delivery, and positive relationships upon which a future organisational structure and opportunities can be developed. It’s an exciting time for both institutions as we move forward in partnership to create something unique and become recognised nationally and internationally as a centre of excellence.”

The proposed merger would continue the already founded positive relations between the institutions, where regular visits, sharing of good practice, and collaborative research work are already taking place. Heads of terms for the potential merger have now been agreed and both institutions are entering into the next phase of discussions, which will include wide consultation with staff, students and other stakeholders to produce a comprehensive implementation plan.

In case this bonanza of platitudes and half-truths has not yet overwhelmed you,  I might be so bold as to ask 10 critical questions:

  1. What is an “evidence-based chiropractic education”? Does it include the messages that 1) subluxation is nonsense, 2) chiropractic manipulations can cause harm, 3) there is little evidence that they do more good than harm?
  2. How  an an “expansion and development of the health and care workforce” be anticipated on the basis of the 3 points I just made?
  3. What does the term “evidence-informed graduates” mean? Does it mean they are informed that you teach them nonsense but instruct them to practice this nonsense anyway?
  4. Do “options to future-proof the institution” include the continuation of misleading the public about the value of chiropractic/osteopathy?
  5. Does the”delivery of excellent osteopathic education, clinical care and research, and opinion leadership” account for the fact that the evidence for osteopathy is weak at best and for most conditions negative?
  6. By “preserving its osteopathic heritage”, do you intend to preserve also the reputation of your founding father, Andrew Taylor Still, who did many dubious things. In 1874, for instance, he was excommunicated by the Methodist Church because of his “laying on of hands”; specifically, he was accused of trying to emulate Jesus Christ, labelled an agent of the Devil, and condemned as practicing voodoo. Or do you prefer to white-wash the osteopathic heritage?
  7. You also want “to protect the chiropractic heritage”; does that mean you aim at white-washing the juicy biography of the charlatan who created chiropractic, DD Palmer, as well?
  8. “UCO and AECC UC already have a common values base” – what are they? As far as I can see, they mainly consist in hiding the truth about the uselessness of your activities from the public.
  9. How do you want to “recognised nationally and internationally as a centre of excellence”? Might it be a good idea to begin by critically assessing your interventions and ask whether they do more good than harm?
  10. Crucially, what is really behing the merger that you are trying to sell us with such concentrated BS?

Anja Zeidler (born 1993) became known in 2012 as the most successful fitness personality in Switzerland. After joining the bodybuilding scene in Los Angeles, a phase of self-discovery followed. Anja published her development and became what one nowadays calls an ‘INFLUENCER’. As Managing Director and Content Director of her own company, Anja Zeidler GmbH, Anja has made a name for herself as a public figure far beyond the fitness market with her activities as a ‘Selflove Influencer’, blogger, book author, motivational speaker, presenter and expert in the food & health sector. Furthermore, she is completing a degree at the Academy of Naturopathy for Holistic Health.

About a year and a half ago, Anja Zeidler had a desmoid tumor removed from under her left breast – and now it was reported to be back. The conventional treatment methods are clear: another surgical procedure or radiation. But Zeidler said she wants to wait with such interventions. For the time being, she has decided to go her own way. She wants to “balance any imbalances” with her naturopathic doctor and wishes to fight the disease on her own and with a “positive mindset.”

“On a spiritual level, they say that tumors can be related to trauma. That’s why I’ve tried breathing exercises and cocoa ceremonies. With these methods, I get into my subconscious and get closer to traumas, which I am not aware of, and try to dissolve them. So far, blatant things have come up that I had long forgotten and repressed,” she says enthusiastically. In addition, Zeidler wants to give up refined sugar with immediate effect, keep better control of her diet in general – even in her stressful everyday life – and drink freshly squeezed celery and beetroot juice every morning. In addition, she relies on “natural capsules with and grape seed OPC.” “I’ve read in studies that certain types of fungi and strong antioxidants like OPC are supposed to fight tumor cells.” There I follow the motto: ‘if it doesn’t help, at least it does not harm.'”

Zeidler’s tumor is a desmoid tumor, an abnormal growth that arises from connective tissues. These tumors are generally not considered malignant because they do not spread to other parts of the body; however, they can aggressively invade the surrounding tissue and can be very difficult to remove surgically. These tumors often recur, even after apparently complete removal.

Zeidler commented: “I am convinced that with a positive mindset you can contribute extremely much to the healing process. If the checks reveal rapid growth, I will of course seek medical treatment. Then I would opt for radiation.”

The trouble with ‘influencers’ is that they are gullible and influence the often gullible public to become more gullible. Thus their influence might cost many lives. Personally, I hope that the young woman does well with her erstwhile refusal of evidence-based treatments. Yet, I fear that the ‘Academy of Naturopathy for Holistic Health’ will teach her a lot of BS about the power of natural cancer cures. The sooner she agrees to have her tumor treated based on evidence, the better her prognosis, I’m sure.

Scientists Katalin Karikó and Drew Weissman, from Hungary and the United States respectively, have received the 2023 Nobel Prize in Physiology or Medicine for discoveries enabling the development of mRNA COVID-19 vaccines.

“The 2023 Nobel Prize in Physiology or Medicine has been awarded to Katalin Karikó and Drew Weissman for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against COVID-19,” the body said. “The laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times.”

Dr Karikó was senior vice-president and head of RNA protein replacement at BioNTech until 2022, and has since acted as an adviser to the company. She is also a professor at the University of Szeged in Hungary, and adjunct professor at the University of Pennsylvania’s Perelman School of Medicine. Dr Weissman is professor in vaccine research at the Perelman School.

Dr Karikó invented a way to prevent the immune system from launching an inflammatory reaction against lab-made mRNA, previously seen as a major hurdle against any therapeutic use of mRNA. Together with Dr Weissman, she showed in 2005 that adjustments to nucleosides  can keep the mRNA under the immune system’s radar.

The Journal ‘Nature’ reported the following:

This year’s Nobel Prize in Physiology or Medicine has been awarded to biochemist Katalin Karikó and immunologist Drew Weissman for discoveries that enabled the development of mRNA vaccines against COVID-19. The vaccines have been administered more than 13 billion times, saved millions of lives and prevented severe COVID-19 in millions of people, said the Nobel committee…

Karikó is the 13th female scientist to win a Nobel Prize in medicine or physiology. She was born in Hungary and later moved to the United States in the 1980s. “Hopefully, this prize will inspire women and immigrants and all of the young ones to persevere and be resilient. That’s what I hope,” she says.

The COVID-19 vaccines developed by Moderna and the Pfizer–BioNTech collaboration deliver mRNA that instructs cells to create SARS-CoV-2’s spike protein, which, in turn, stimulates the body to make antibodies.

“The ideas that she and Drew Weismann developed were critical for the success of RNA vaccines,” said John Tregoning, a vaccine immunologist at Imperial College London, in a press statement for the UK Science Media Centre. “They demonstrated that changing the type of the RNA nucleotides within the vaccine altered the way in which cells see it. This increased the amount of vaccine protein made following the injection of the RNA, effectively increasing the efficiency of the vaccination: more response for less RNA.”

“This discovery has opened a new chapter for medicine,” said Nobel committee member Qiang Pan-Hammarström, an immunologist at the Karolinska Institute in Stockholm, at a press conference following the prize announcement. “Investment in long-term basic research is very important.”

“It’s really like a revolution starting since the COVID pandemic,” says Rein Verbeke, an mRNA vaccine researcher at the University of Ghent in Belgium. He adds that Karikó and Weissman’s contributions were essential to the vaccines’ success during the pandemic, and beyond. “Their part was really crucial to the development of this platform.” …

The development of mRNA vaccines and therapeutics is in its infancy, says Robin Shattock, who studies vaccines, infections and immunity at Imperial College London. Scientists and biotechnology companies are busy coming up with new applications for mRNA technology, from cancer treatments to next-generation COVID-19 vaccines. Many teams are also working on improved ways of delivering mRNA. “What we see used today is not what it’s going to be used in the future,” says Shattock. “We’re at the beginning of an RNA revolution. The technology is really taking off.”

___________________________

On this blog, we had an abundance of discussions about mRNA vaccines. I wonder whether the anti-vaxx brigade will now consider their position. More likely, however, they will merely claim that the Nobel committe is just another element in the big conspiracy that is about to kill us all.

The COVID-19 pandemic has been notable for the widespread dissemination of misinformation regarding the virus and appropriate treatment. The  objective of this study was to quantify the prevalence of non–evidence-based treatment for COVID-19 in the US and the association between such treatment and endorsement of misinformation as well as lack of trust in physicians and scientists.

This single-wave, population-based, nonprobability internet survey study was conducted between December 22, 2022, and January 16, 2023, in US residents 18 years or older who reported prior COVID-19 infection.

Self-reported use of ivermectin or hydroxychloroquine, endorsing false statements related to COVID-19 vaccination, self-reported trust in various institutions, conspiratorial thinking measured by the American Conspiracy Thinking Scale, and news sources.

A total of 13 438 individuals (mean [SD] age, 42.7 [16.1] years; 9150 [68.1%] female and 4288 [31.9%] male) who reported prior COVID-19 infection were included in this study. In this cohort, 799 (5.9%) reported prior use of hydroxychloroquine (527 [3.9%]) or ivermectin (440 [3.3%]). In regression models including sociodemographic features as well as political affiliation, those who endorsed at least 1 item of COVID-19 vaccine misinformation were more likely to receive non–evidence-based medication (adjusted odds ratio [OR], 2.86; 95% CI, 2.28-3.58). Those reporting trust in physicians and hospitals (adjusted OR, 0.74; 95% CI, 0.56-0.98) and in scientists (adjusted OR, 0.63; 95% CI, 0.51-0.79) were less likely to receive non–evidence-based medication. Respondents reporting trust in social media (adjusted OR, 2.39; 95% CI, 2.00-2.87) and in Donald Trump (adjusted OR, 2.97; 95% CI, 2.34-3.78) were more likely to have taken non–evidence-based medication. Individuals with greater scores on the American Conspiracy Thinking Scale were more likely to have received non–evidence-based medications (unadjusted OR, 1.09; 95% CI, 1.06-1.11; adjusted OR, 1.10; 95% CI, 1.07-1.13).

The authors concluded that, in this survey study of US adults, endorsement of misinformation about the COVID-19 pandemic, lack of trust in physicians or scientists, conspiracy-mindedness, and the nature of news sources were associated with receiving non–evidence-based treatment for COVID-19. These results suggest that the potential harms of misinformation may extend to the use of ineffective and potentially toxic treatments in addition to avoidance of health-promoting behaviors.

This study made me wonder to what extend a lack of trust in physicians or scientists, and conspiracy-mindedness are also linked to the use of so-called alternative medicine (SCAM) for treatning COVID infections. As I have often discussed, such associations have been reported regularly, e.g.:

The authors point out that the endorsement of misinformation related to COVID-19 has been shown to decrease the intention to vaccinate against COVID-19, to decrease the belief that it is required for herd immunity, and to correlate with forgoing various COVID-19 prevention behaviors. Such false information is largely spread online and often originates as disinformation intentionally spread by political actors and media sources, as well as illicit actors who profit from touting supposed cures for COVID-19.  A substantial minority of the public endorses false information related to COVID-19, although certain subgroups are more likely to do so, including those who are more religious, who distrust scientists, and who hold stronger political affiliations. Cultivating and maintaining trust is a crucial factor in encouraging the public to engage in prosocial health behaviors. The extent to which addressing conspiratorial thinking could represent a strategy to address obstacles to public health merits further investigation.
