I hope you are as impressed as I am!

So, I searched for the evidence?

Does detox work? Specifically, does the Nuubu reduce my:

  • Brain Fog
  • Irritability
  • Exhaustion
  • Stress Induced Muscle Aches
  • Inability to Concentrate
  • Tiredness
  • Restlessness
  • And Many More Problems

No matter how hard I searched, I did not find any evidence. Eventually, I had to conclude that the patch does not work.

Hold on!

The website might be correct with one claim: it helps you to strengthen your mind

… to such an extend that you will

never fall for the lies of detox entrepreneurs!

The WHO has just released guidelines for non-surgical management of chronic primary low back pain (CPLBP). The guideline considers 37 types of interventions across five intervention classes. With the guidelines, WHO recommends non-surgical interventions to help people experiencing CPLBP. These interventions include:

  • education programs that support knowledge and self-care strategies;
  • exercise programs;
  • some physical therapies, such as spinal manipulative therapy (SMT) and massage;
  • psychological therapies, such as cognitive behavioural therapy; and
  • medicines, such as non-steroidal anti-inflammatory medicines.

The guidelines also outline 14 interventions that are not recommended for most people in most contexts. These interventions should not be routinely offered, as WHO evaluation of the available evidence indicate that potential harms likely outweigh the benefits. WHO advises against interventions such as:

  • lumbar braces, belts and/or supports;
  • some physical therapies, such as traction;
  • and some medicines, such as opioid pain killers, which can be associated with overdose and dependence.

As you probably guessed, I am particularly intrigued by the WHO’s positive recommendation for SMT. Here is what the guideline tells us about this specific topic:

Considering all adults, the guideline development group (GDG) judged overall net benefits [of spinal manipulation] across outcomes to range from trivial to moderate while, for older people the benefit was judged to be largely uncertain given the few trials and uncertainty of evidence in this group. Overall, harms were judged to be trivial to small for all adults and uncertain for older people due to lack of evidence.

The GDG commented that while rare, serious adverse events might occur with SMT, particularly in older people (e.g. fragility fracture in people with bone loss), and highlighted that appropriate training and clinical vigilance concerning potential harms are important. The GDG also acknowledged that rare serious adverse events were unlikely to be detected in trials. Some GDG members considered that the balance of benefits to harms favoured SMT due to small to moderate benefits while others felt the balance did not favour SMT, mainly due to the very low certainty evidence for some of the observed benefits.

The GDG judged the overall certainty of evidence to be very low for all adults, and very low for older people, consistent with the systematic review team’s assessment. The GDG judged that there was likely to be important uncertainty or variability among people with CPLBP with respect to their values and preferences, with GDG members noting that some people might prefer manual
therapies such as SMT, due to its “hands-on” nature, while others might not prefer such an approach.

Based on their experience and the evidence presented from the included trials which offered an average of eight treatment sessions, the GDG judged that SMT was likely to be associated with moderate costs, while acknowledging that such costs and the equity impacts from out-of-pocket costs would vary by setting.

The GDG noted that the cost-effectiveness of SMT might not be favourable when patients do not experience symptom improvements early in the treatment course. The GDG judged that in most settings, delivery of SMT would be feasible, although its acceptability was likely to vary across
health workers and people with CPLBP.

The GDG reached a consensus conditional recommendation in favour of SMT on the basis of small to moderate benefits for critical outcomes, predominantly pain and function, and the likelihood of rare adverse events.

The GDG concluded by consensus that the likely short-term benefits outweighed potential harms, and that delivery was feasible in most settings. The conditional nature of the recommendation was informed by variability in acceptability, possible moderate costs, and concerns that equity might be negatively impacted in a user-pays model of financing.

___________________________

This clearly is not a glowing endorsement or recommendation of SMT. Yet, in my view, it is still too positive. In particular, the assessment of harm is woefully deficient. Looking into the finer details, we find how the GDG assessed harms:

WHO commissioned quantitative systematic evidence syntheses of randomized controlled
trials (RCTs) to evaluate the benefits and harms (as reported in included trials) of each of the
prioritized interventions compared with no care (including trials where the effect of an
intervention could be isolated), placebo or usual care for each of the critical outcomes (refer to Table 2 for the PICO criteria for selecting evidence). Research designs other than RCTs
were not considered.

That explains a lot!

It is not possible to establish the harms of SMT (or any other therapy) on the basis of just a few RCTs, particularly because the RCTs in question often fail to report adverse events. I can be sure of this phenomenon because we investigated it via a systematic review:

Objective: To systematically review the reporting of adverse effects in clinical trials of chiropractic manipulation.

Data sources: Six databases were searched from 2000 to July 2011. Randomised clinical trials (RCTs) were considered, if they tested chiropractic manipulations against any control intervention in human patients suffering from any type of clinical condition. The selection of studies, data extraction, and validation were performed independently by two reviewers.

Results: Sixty RCTs had been published. Twenty-nine RCTs did not mention adverse effects at all. Sixteen RCTs reported that no adverse effects had occurred. Complete information on incidence, severity, duration, frequency and method of reporting of adverse effects was included in only one RCT. Conflicts of interests were not mentioned by the majority of authors.

Conclusions: Adverse effects are poorly reported in recent RCTs of chiropractic manipulations.

The GDG did not cite our review (or any other of our articles on the subject) but, as it was published in a very well-known journal, they must have been aware of it. I am afraid that this wilfull ignorance caused the WHO guideline to underestimate the level of harm of SMT. As there is no post-marketing surveillance system for SMT, a realistic assessment of the harm is far from easy and needs to include a carefully weighted summary of all the published reports (such as this one).

The GDG seems to have been aware of (some of) these problems, yet they ignored them and simply assumed (based on wishful thinking?) that the harms were small or trivial.

Why?

Even the most cursory look at the composition of the GDG, begs the question: could it be that the GDG was highjacked by chiropractors and other experts biased towards SMT?

The more I think of it, the more I feel that this might actually be the case. One committee even listed an expert, Scott Haldeman, as a ‘neurologist’ without disclosing that he foremost is a chiropractor who, for most of his professional life, has promoted SMT in one form or another.

Altogether, the WHO guideline is, in my view, a shameful example of pro-chiropractic bias and an unethical disservice to evidence-based medicine.

 

Some articles are just too remarkable for me to alter them in any way. This one impresses already by its title: “Ameliorative effects of homeopathic medicines in the management of different cancers“. By way of a ‘Christmas treat’, here its summary:

Homeopathy is a commonly used complementary and alternative system of medicine for the treatment of various sorts of ailments throughout the world. Homeopathic medicines are made up of potential therapeutic natural products that are primarily acknowledged for their low doses as well as extended patient survival results. Homeopathic medicines are derived from plants such as arnica (mountain herb), red onion, poison ivy, stinging nettle, and belladonna (deadly nightshade); minerals including white arsenic as well as from animals such as crushed whole bees. Homeopathic medicines are synthesized as sugar pellets to be placed under the tongue and may also be used in the form of gels, ointments, drops, tablets, and creams. Homeopathic medicines can be used to treat various disorders including migraine, depression, gastrointestinal diseases, joint pain, inflammation, different sorts of injuries, flu, arthritis as well as sciatica.

Cancer is the 2nd major reason behind global mortalities. It is revealed that developing countries around the world shoulder most of the cancer burden. According to a survey conducted in 2020, low- and middle-income countries face 70% of the total mortalities worldwide which accounts for approximately 10 million people of these countries. Homeopathic medicines ensure low-cost cancer treatment with little or no side effects on the bodies of humans and animals. Besides, it is applied as a supportive and palliative therapy in a broad range of cancer patients to enhance the body’s fight against cancer, alleviate discomfort resulting from disease or conventional treatments as well as improve the general well-being of the patients. In this chapter, our primary focus will be on the anti-cancerous effects of homeopathic medicines against different cancerous conditions in the body along with their mechanism of action.

Let me just mention a few fairly obvious points:

My conclusion:

Those who advocate homeopathy don’t know what it is, while those who know what it is, don’t advocate it.

Need to find a last-minute Christmas present?

What about the ‘libido-boosting soft drink G Spot? That surely would make a wonderful holiday season (provided the drink does not get highjacked by your mother-in-law). Here is more info, in case you are interested:

Launched in May 2023, the line of plant-based sparkling drinks include “life-enhancing adaptogens and nootropics that invigorate and boost performance and cognitive functions”.

“I’ve had a serious soft drink habit for the past 20 years, and I don’t drink enough water,” Gillian Anderson (OBE), the firm’s founder and brain behind the drinks, said. “I know sugar and caffeine are not good for me, but I haven’t found an alternative that has the same effect. And although I love the idea of flavoured water, I really don’t like the taste of what’s out there. So, I thought, if what I’m looking for doesn’t exist, why don’t I make it?”

Arouse, specifically, has been designed to “awaken your senses” with Passionfruit, White Peach and Habanero, blended expertly with functional ingredients, including: Butterfly Pea (Clitoria ternatea), a plant species used in traditional medicine as an aphrodisiac; I-Arginine and I-Citrulline, amino acids which increase blood flow to sexual organs to improve libido; and Vitamin B6, a nutrient that regulates sexual hormones.

“At G Spot, we believe wellness is due a fresh take. One that’s less intense and anxiety inducing. One that truly makes you feel good, without guilt or inhibition. Our newest drink, Arouse, embodies our commitment to this philosophy. Arouse isn’t just a flavour; it’s an experience!” says CEO Rebekah Hall.

Named after their intended effects, the rest of the line comes in the form of Lift, combining berry, apply and peppercorn flavors with the wellbeing benefits of bacopa, theanine, cordyceps, and lion’s mane (boosting energy levels, stamina, and brain power while also combating stress); Protect, blending meadowsweet, ginger, lemon, turmeric, peppercorn and chaga (offering additional immune system-boosting benefits)’ and Soothe, which combines apples, sage, and cornflower with magnesium, maca, reishi, and ashwagandha (which works to relax the body as it benefits from the brand-wide libido boost).

All G Spot drinks available online in 6- and 12-pack bundles (250ml per can), as well as in Harvey Nichols (in-store and online) in the UK.

Prices range from £3.50 to £29.99 ($4.28 to $36.54).

The drinks are advertised to invigorate and boost performance and cognitive functions.

Any evidence for these medicinal claims?

Sadly not – at least I could not find any.

A case for the Advertising Standards Agency (ASA)?

Possibly!

 

As promised, here is my translation of the article published yesterday in ‘Le Figaro’ arguing in favour of integrating so-called alternative medicine (SCAM) into the French healthcare system [the numbers in square brackets were inserted by me and refer to my comments listed at the bottom].

So-called unconventional healthcare practices (osteopathy, naturopathy, acupuncture, homeopathy and hypnosis, according to the Ministry of Health) are a cause for concern for the health authorities and Miviludes, which in June 2023 set up a committee to support the supervision of unconventional healthcare practices, with the task of informing consumers, patients and professionals about their benefits and risks, both in the community and in hospitals. At the time, various reports, surveys and press articles highlighted the risks associated with NHPs, without pointing to their potential benefits [1] in many indications, provided they are properly supervised. There was panic about the “booming” use of these practices, the “explosion” of aberrations, and the “boost effect” of the pandemic [2].

But what are the real figures? Apart from osteopathy, we lack reliable data in France to confirm a sharp increase in the use of these practices [3]. In Switzerland, where it has been decided to integrate them into university hospitals and to regulate the status of practitioners who are not health professionals, the use of NHPs has increased very slightly [4]. With regard to health-related sectarian aberrations, referrals to Miviludes have been stable since 2017 (around 1,000 per year), but it should be pointed out that they are a poor indicator of the “risk” associated with NHPs (unlike reports). The obvious contrast between the figures and the press reports raises questions [5]. Are we witnessing a drift in communication about the risks of ‘alternative’ therapies? [6] Is this distortion of reality [7] necessary in order to justify altering the informed information and freedom of therapeutic choice of patients, which are ethical and democratic imperatives [8]?

It is the inappropriate use of certain NHPs that constitutes a risk, more than the NHPs themselves! [9] Patients who hope to cure their cancer with acupuncture alone and refuse anti-cancer treatments are clearly using it in a dangerous alternative way [10]. However, acupuncture used to relieve nausea caused by chemotherapy, as a complement to the latter, is recommended by the French Association for Supportive Care [11]. The press is full of the dangers of alternative uses, but they are rare: less than 5% of patients treated for cancer according to a European study [12]. This is still too many. Supervision would reduce this risk even further [13].

Talking about risky use is therefore more relevant than listing “illusory therapies”, vaguely defined as “not scientifically validated” and which are by their very nature “risky” [14]. What’s more, it suggests that conventional treatments are always validated and risk-free [15]. But this is not true! In France, iatrogenic drug use is estimated to cause over 200,000 hospital admissions and 10,000 deaths a year [16]. Yes, some self-medication with phytotherapy or aromatherapy does carry risks… just like any self-medication with conventional medicines [17]. Yes, acupuncture can cause deep organ damage, but these accidents occur in fewer than 5 out of every 100,000 patients [18]. Yes, cervical manipulations by osteopaths can cause serious or even fatal injuries, but these exceptional situations are caused by practitioners who do not comply with the decree governing their practice.[19] Yes, patients can be swindled by charlatans, but there are also therapeutic and financial abuses in conventional medicine, such as those reported in dental and ophthalmology centres. [20]

Are patients really that naive? No. 56% are aware that “natural” remedies can have harmful side-effects, and 70% know that there is a risk of sectarian aberrations or of patients being taken in by a sect [21]. In view of the strong demand from patients, we believe that guaranteeing safe access to certain NHPs is an integral part of their supervision, based on regulation of the training and status of practitioners who are not health professionals, transparent communication, appropriate research, the development of hospital services and outpatient networks of so-called “integrative” medicine combining conventional practices and NHPs, structured care pathways with qualified professionals, precise indications and a safe context for treatment.[22] This pragmatic approach to reducing risky drug use [17] has demonstrated its effectiveness in addictionology [23]. It should inspire decision-makers in the use of NHPs”.

  1. Reports about things going wrong usually do not include benefits. For instance, for a report about rail strikes it would be silly to include a paragraph on the benefits of rail transport. Moreover, it is possible that the benefits were not well documented or even non-existent.
  2. No, there was no panic but some well-deserved criticism and concern.
  3. Would it not be the task of practitioners to provide reliable data of their growth or decline?
  4. The situation in Switzerland is often depicted by enthusiasts as speaking in favour of SCAM; however, the reality is very different.
  5. Even if reports were exaggerated, the fact is that the SCAM community does as good as nothing to prevent abuse.
  6. For decades, these therapies were depicted as gentle and harmless (medicines douces!). As they can cause harm, it is high time that there is a shift in reporting and consumers are informed responsibly.
  7. What seems a ‘distortion of reality’ to enthusiasts might merely be a shift to responsible reporting akin to that in conventional medicine where emerging risks are taken seriously.
  8. Are you saying that informing consumers about risks is not an ethical imperative? I’d argue it is an imperative that outweighs all others.
  9. What if both the inappropriate and the appropriate use involve risks?
  10.  Sadly, there are practitioners who advocate this type of usage.
  11. The recommendation might be outdated; current evidence is far less certain that this treatment might be effective (“the certainty of evidence was generally low or very low“)
  12. The dangers depend on a range of factors, not least the nature of the therapy; in case of spinal manipulation, for instance, about 50% of all patients suffer adverse effects which can be severe, even fatal.
  13. Do you have any evidence showing that supervision would reduce this risk, or is this statement based on wishful thinking?
  14. As my previous comments demonstrate, this statement is erroneous.
  15. No, it does not.
  16. Even if this figure is correct, we need to look at the risk/benefit balance. How many lives were saved by conventional medicine?
  17. Again: please look at the risk/benefit balance.
  18. How can you be confident about these figures in the absence of any post-marketing surveillance system? The answer is, you cannot!
  19. No, they occur even with well-trained practitioners who comply with all the rules and regulations that exist – spoiler: there hardly are any rules and regulations!
  20. Correct! But this is a fallacious argument that has nothing to do with SCAM. Please read up about the ‘tu quoque’ and the strawman’ fallacies.
  21. If true, that is good news. Yet, it is impossible to deny that thousands of websites try to convince the consumer that SCAM is gentle and safe.
  22. Strong demand is not a substitute for reliable evidence. In any case, you stated above that demand is not increasing, didn’t you?
  23. Effectiveness in addictionology? Do you have any evidence for this or is that statement also based on wishful thinking?

My conclusion after analysing this article in detail is that it is poorly argued, based on misunderstandings, errors, and wishful thinking. It cannot possibly convince rational thinkers that SCAM should be integrated into conventional healthcare.

Due to the common adverse effects of motion sickness pharmaceuticals (e.g., drowsiness), medication options to treat the condition are limited. Thus many non-pharmacological therapies are being advocated for it. One of them is osteopathy.

The purpose of this study was to explore the potential utility of a nonpharmaceutical method for motion sickness prevention, specifically an osteopathic manipulative technique (OMT). A novel OMT protocol for the reduction of motion sickness symptoms and severity was evaluated using a sham-controlled, counterbalanced, between-subjects study design. The independent variable was OMT treatment administered prior to the motion sickness-inducing procedure (rotating chair). The primary dependent measures were total and subscale scores from the Motion Sickness Assessment Questionnaire.

The OMT treatment group experienced significantly fewer gastrointestinal (mean scores postprocedure, treatment M = 20.42, sham M = 41.67) and sopite-related (mean scores postprocedure, treatment M = 12.81, sham M = 20.68) symptoms than the sham group while controlling for motion sickness susceptibility. There were no differences between groups with respect to peripheral and central symptoms.

The authors concluded that the results suggest that the treatment may prevent gastrointestinal (nausea) and sopite-related symptoms (sleepiness). These preliminary findings support further exploration of OMT for the prevention of motion sickness. A more precise evaluation of the mechanism of action is needed. Additionally, the duration of the effects needs to be investigated to determine the usefulness of this technique in training and operational settings.

Motion sickness is one of those conditions for which many forms of so-called alternative medicine (SCAM) have been tried and found in dodgy studies to be promissing, e.g.:

And now even OMT!

But before we rush into doing further research on this topic, we should perhaps ask whether the trial really does show OMT to be effective. Unfortunately, the article is behind a paywall, and I can therefore only speculate and ask whether the sham procedure was credible. Was the success of patient-blinding tested? I suspect it wasn’t. If that is so, it could mean that the OMT itself was not the reason for the results but that patient expectation caused the reported outcomes.

In any case, if nothing else, this paper shows yet again that the notion of OMT being an option purely for spinal problems is fantasy. Its advocates try everything to get it accepted as a cure all.

 

The purpose of this systematic review was to assess the effectiveness and safety of conservative interventions compared with other interventions, placebo/sham interventions, or no intervention on disability, pain, function, quality of life, and psychological impact in adults with cervical radiculopathy (CR), a painful condition caused by the compression or irritation of the nerves that supply the shoulders, arms and hands.

A multidisciplinary team autors searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022 to identify studies that were:

  1. randomized trials,
  2. had at least one conservative treatment arm,
  3. diagnosed participants with CR through confirmatory clinical examination and/or diagnostic tests.

Studies were appraised using the Cochrane Risk of Bias 2 tool and the quality of the evidence was rated using the Grades of Recommendations, Assessment, Development, and Evaluation approach.

Of the 2561 records identified, 59 trials met the inclusion criteria (n = 4108 participants). Due to clinical and statistical heterogeneity, the findings were synthesized narratively.

There is very-low certainty evidence supporting the use of:

  • acupuncture,
  • prednisolone,
  • cervical manipulation,
  • low-level laser therapy

for pain and disability in the immediate to short-term, and

  • thoracic manipulation,
  • low-level laser therapy

for improvements in cervical range of motion in the immediate term.

There is low to very-low certainty evidence for multimodal interventions, providing inconclusive evidence for pain, disability, and range of motion.

There is inconclusive evidence for pain reduction after conservative management compared with surgery, rated as very-low certainty.

The authors concluded that there is a lack of high-quality evidence, limiting our ability to make any meaningful conclusions. As the number of people with CR is expected to increase, there is an urgent need for future research to help address these gaps.

I agree!

Yet, to patients suffering from CR, this is hardly constructive advice. What should they do vis a vis such disappointing evidence?

They might speak to a orthopedic surgeon; but often there is no indication for an operation. What then?

Patients are bound to try some of the conservative options – but which one?

  • Acupuncture?
  • Prednisolone?
  • Cervical manipulation,?
  • Low-level laser therapy?

My advice is this: be patient – the vast majority of cases resolves spontaneously regardless of therapy – and, if you are desperate, try any of them except cervical manipulation which is burdened with the risk of serious complications and often makes things worse.

So-called alternative medicine (SCAM) interventions are often being discussed as possible treatments for long COVID symptoms. However, comprehensive analysis of current evidence in this setting is still lacking. This review aims to review existing published studies on the use of SCAM interventions for patients experiencing long COVID through a systematic review.

A comprehensive electronic literature search was performed in multiple databases and clinical trial registries from September 2019 to January 2023. RCTs evaluating efficacy and safety of SCAM for long COVID were included. Methodological quality of each included trial was appraised with the Cochrane ‘risk of bias’ tool. A qualitative analysis was conducted due to heterogeneity of included studies.

A total of 14 RCTs with 1195 participants were included in this review. Study findings demonstrated that SCAM interventions could benefit patients with long COVID, especially those suffering from neuropsychiatric disorders, olfactory dysfunction, cognitive impairment, fatigue, breathlessness, and mild-to-moderate lung fibrosis. The main interventions reported were self-administered transcutaneous auricular vagus nerve stimulation, neuro-meditation, dietary supplements, olfactory training, aromatherapy, inspiratory muscle training, concurrent training, and an online breathing and well-being program.

The authors concluded that SCAM interventions may be effective, safe, and acceptable to patients with symptoms of long COVID. However, the findings from this systematic review should be interpreted with caution due to various methodological limitations. More rigorous trials focused on SCAM for long COVID are warranted in the future.

The review’s aim is, in my view, nonsense. SCAM is a diverse field which means that the review must capture a wide range of therapies each represented by just one or two primary studies. In turn, this means that general conclusions across all SCAM will be highly questionable, if not misleading.

Furthermore, I find these conclusions odd and irresponsibly misleading. My main reason for this is the poor methodological quality of the primary studies:

  • Four trials were considered to have unknown bias risk for generating the random sequence due to insufficient information about the specific method of randomization used.
  • Only 5 of the trials provided appropriate random allocation concealment.
  • Only 5 trials were blinded to both participants and personnel.
  •  Three trials were rated as unknown risk of bias since insufficient information was provided.
  • Four trials failed to performed outcome assessment blinding.
  • One trial did not report detailed information about drop-out cases and was defined as high risk of bias. 
  • Three study protocols were unavailable and had relevant outcomes that were not reported in the pre-specified way.

Moreover, safety cannot possibly be reliably estimated on the basis of the data. And finally, the statement that SCAM interventions may be effective, as the authors put it, is in my view not a valid conclusion but a silly platitude.

I therefore suggest to re-formulate the conclusion of this review as follows:

At present there is no sound evidence to assume that any SCAM intervention is effective in the management of long COVID.

I was alerted to the updated and strengthened guidance to ensure safer practice by chiropractors who treat children under the age of 12 years that has recently been published by the Chiropractic Board of Australia after considering the recommendations made by the Safer Care Victoria independent review. The Board also considered community needs and expectations, and specifically the strong support for consumer choice voiced in the public consultation of the independent review.

The Board examined how common themes in the independent review’s recommendations align with its existing regulatory guidance, and used these insights to inform a risk-based approach to updating its Statement on paediatric care. This includes updated advice reinforcing the need to ensure that parents or guardians fully understand their rights and the evidence before treatment is provided to children. ‘Public safety is our priority, and especially so when we consider the care of children’, Board Chair Dr Wayne Minter said.

According to the statement, the Board expects chiropractors to various things, including the following [the numbers in the following passage were added by me and refer to my brief comments below]:

  • inform the patient and their parent/guardian about the quality of the acceptable evidence and explain the basis for the proposed treatment [1]
  • provide the patient and their parent/guardian with information about the risks and benefits of the proposed treatment and the risks of receiving no treatment [2]
  • appropriately document consent, including considering the need for written consent for high-risk procedures [3]
  • refer patients when they have conditions or symptoms outside a chiropractor’s area of competence, for example ‘red flags’ such as the presence of possible serious pathology that requires urgent medical referral to the care of other registered health practitioners [4]

______________________________

  1. I know what is meant by the ‘quality of the evidence’ but am not sure what to make of the ‘quality of the acceptable evidence]. Acceptable by whom? In any case, who checks whether this information is being provided?
  2. Imagine the scenatio following this guidance: Chiro informs that there is a serious risk and no proven benefit – which parent would then procede with the treatment? In any case, the informed consent is incomplete because it also requires information as to which conventional treatment is effective for the condition at had [information that chiros are not competent to provide].
  3. Who checks whether this is done properly?
  4. Arguably, all pediatric conditions or symptoms are outside a chiropractor’s area of competence!

In view of these points, I fear that the updated guidance is a transparent attempt of window dressing, yet unfit for purpose. Most certainly, it does not ensure safer practice by chiropractors who treat children under the age of 12 years.

Despite effective vaccines, there is still a need for effective treatments for COVID, especially for people in the community. Dietary supplements have long been used to treat respiratory infections, and preliminary evidence indicates some may be effective in people with COVID-19. This study tested whether a combination of vitamin C, vitamin D3, vitamin K2 and zinc would improve overall health and decrease symptom burden in outpatients diagnosed with COVID-19.

Participants were randomised to receive either vitamin C (6 g), vitamin D3 (1000 units), vitamin K2 (240 μg) and zinc acetate (75 mg) or placebo daily for 21 days and were followed for 12 weeks. An additional loading dose of 50 000 units vitamin D3 (or placebo) was given on day one. The primary outcome was participant-reported overall health using the EuroQol Visual Assessment Scale summed over 21 days. Secondary outcomes included health status, symptom severity, symptom duration, delayed return to usual health, frequency of hospitalisation and mortality.

A total of 90 patients (46 control, 44 treatment) were randomised. The study was stopped prematurely due to insufficient capacity for recruitment. The mean difference (control-treatment) in cumulative overall health was -37.4 (95% CI -157.2 to 82.3), p=0.53 on a scale of 0-2100. No clinically or statistically significant differences were seen in any secondary outcomes.

The authors concluded that, in this double-blind, placebo-controlled, randomised trial of outpatients diagnosed with COVID-19, the dietary supplements vitamin C, vitamin D3, vitamin K2 and zinc acetate showed no clinically or statistically significant effects on the documented measures of health compared with a placebo when given for 21 days. Termination due to feasibility limited our ability to demonstrate the efficacy of these supplements for COVID-19. Further research is needed to determine clinical utility.

In several ways I am puzzled by this study. On the other hand, I should congratulate the naturopathic authors for honestly reporting such a squarely negative result. One could, of course, argue that the study was under-powered and that thus the findings are not conclusive. However, the actual survival curve depicting the results show clearly that there was not even the tiniest trend for the supplement to show any effect. In other words, a larger sample would have most likely yielded the same result.

Participants randomised to the treatment arm received:

  1. Vitamin D3 50 000 units orally once on day 1 of the study (capsule).
  2. Vitamin K2/D3 120 μg/500 units orally two times per day for 21 days (liquid).
  3. Vitamin C/Zinc acetate 2 g/25 mg orally three times daily for 21 days (capsule).

I fail to understand why the researchers might have conceived the hypothesis that such a mixture would be effective. Only 90 of a planned 200 participants were enrolled in this study which ran between September 2021 and April 2022. I fail to understand why recruitment was so poor that the study eventually had to be aborted. My speculation is that the naturopaths in charge of running the trial were too inexperienced in conducting such research to make it a success.

The study was supported by the Ottawa Integrative Cancer Centre Foundation and by Mavis and Martin Sacher. All investigational products for this study were provided in-kind by New Roots Herbal. Perhaps in future these sponsors should think again before they support amateurs pretending to be scientists?
