critical thinking
If you think that scanning through dozens of new scientific articles every week is a dry and often somewhat tedious exercise, you are probably correct. But every now and then, this task is turned into prime entertainment by some pseudoscientists trying to pretend to be scientists. Take, for instance, the latest homeopathy study by Indian researchers with no less than 9 seemingly impressive affiliations:
- 1Department of Organon of Medicine and Homoeopathic Philosophy, National Institute of Homoeopathy, Ministry of AYUSH, Govt. of India, Salt Lake, Kolkata, West Bengal, India.
- 2Department of Organon of Medicine and Homoeopathic Philosophy, National Institute of Homoeopathy, Ministry of AYUSH, Govt. of India, Block GE, Sector III, Salt Lake, Kolkata, West Bengal, India.
- 3Department of Homoeopathy, State Homoeopathic Dispensary, Karaila, Pratapgarh, Uttar Pradesh, India.
- 4Department of Homoeopathy, State Homoeopathic Dispensary, Tulsipur, Shrawasti, Uttar Pradesh, India.

Now that I have whetted your appetite, here is their study:
Lumbar spondylosis (LS) is a degenerative disorder of the lumbar spine. Despite substantial research efforts, no gold-standard treatment for LS has been identified. The efficacy of individualized homeopathic medicines (IHMs) in lumbar spondylosis (LS) is unknown. In this double-blind, randomized, placebo-controlled trial, the efficacy of IHMs was compared with identical-looking placebos in the treatment of low back pain associated with LS. It was conducted at the National Institute of Homoeopathy, West Bengal, India.
Patients were randomized to receive IHMs or placebos; standardized concomitant care was administered in both groups. The Oswestry low back pain and disability questionnaire (ODQ) was used as the primary outcome measure; the Roland-Morris questionnaire (RMQ) and the short form of the McGill pain questionnaire (SF-MPQ) served as secondary outcome measures. They were measured at baseline and every month for 3 months. Intention-to-treat analyses (ITT) were used to detect any inter-group differences using two-way repeated measures analysis of variance models overall and by unpaired t-tests at different time points.
Enrolment was stopped prematurely because of time restrictions; 55 patients had been randomized (verum: 28; control: 27); 49 could be analyzed by ITT (verum: 26; control: 23).
The results are as follows:
- Inter-group differences in ODQ (F 1, 47 = 0.001, p = 0.977), RMQ (F 1, 47 = 0.190, p = 0.665) and SF-MPQ total score (F 1, 47 = 3.183, p = 0.081) at 3 months were not statistically significant.
- SF-MPQ total score after 2 months (p = 0.030) revealed an inter-group statistical significance, favoring IHMs against placebos.
- Some of the SF-MPQ sub-scales at different time points were also statistically significant: e.g., the SF-MPQ average pain score after 2 months (p = 0.002) and 3 months (p = 0.007).
- Rhus Toxicodendron, Sulphur, and Pulsatilla nigricans were the most frequently indicated medicines.
The authors concluded that owing to failure in detecting a statistically significant effect for the primary outcome and in recruiting a sufficient number of participants, our trial remained inconclusive.
Now that I (and hopefully you too) have recovered from laughing out loud, let me point out why this paper had me in stitches:
- The trial was aborted not because of a “time limit” but because of slow recruitment, I presume. The question is why were not more patients volunteering? Low back pain with LS is extremely common. Could it be that patients know only too well that homeopathy does not help with low back pain?
- If a trial gets aborted because of very low patient numbers, it is probably best not to publish it or at least not to evaluate its results at all.
- If the researchers insist on publishing it, their paper should focus on the reason why it did not succeed so that others can learn from their experience by avoiding their mistakes.
- However, once the researchers do run statistical tests, they should be honest and conclude clearly that, because the primary outcome measure showed no inter-group difference, the study failed to demonstrate that the treatment is effective.
- The trial did not “remain inconclusive”; it was squarely negative.
- The editor of the journal HOMEOPATHY should know better than to publish such nonsense.
A final thought: is it perhaps the ultimate proof of homeopathy’s ‘like cures like’ assumption to use sound science (i.e. an RCT), submit it to the homeopathic process of endless dilutions and succussions, and – BINGO – generate utter nonsense?
About 3 years ago, I reported that the Bavarian government had decided to fund research into the question of whether the use of homeopathy would reduce the use of antibiotics (an idea that also King Charles fancies). With the help of some friends, I found further details of the project. Here are some of them:
The study on individualized homeopathic treatment to reduce the need for antibiotics in patients with recurrent urinary tract infections is a randomized, placebo-controlled, multicenter, double-blind trial. Frequent urinary tract infections (more than two infections within six months or more than three infections within twelve months) occur in up to three percent of all women during their lifetime and represent a high risk for increased antibiotic use in this population.
The current guidelines therefore also provide for therapeutic approaches without antibiotic administration under close monitoring. The approach to be investigated in the study is the administration of a homeopathic medicine individually selected for the patient for prophylaxis. The number of urinary tract infections and the need for antibiotics will be recorded and evaluated at the end of the trial period, around mid to late 2023.
The aim of the study is to find out whether patients taking homeopathics need antibiotics for the treatment of urinary tract infections less often compared to the placebo group. This could lead to a reduction in the use of antibiotics for recurrent urinary tract infections.
Project participants: Technical University of Munich, Klinikum Rechts der Isar
Project funding: 709,480.75 Euros
Project duration: January 1, 2021 to December 31, 2023

This sketch is of course not enough for providing a full evaluation of the study concept (if someone has more details, I’d be interested to learn more). From the little information given above, I feel that:
- the design of the trial might be quite rigorous,
- a fairly large sample will be required to have enough power,
- the closing date of 31/12/2023 seems optimistic (but this obviously depends on the number of centers cooperating),
- I, therefore, predict that we will have to wait a long time for the results (the pandemic and other obstacles will have delayed recruitment),
- the costs of the trial are already substantial and might increase due to delays etc.
My main criticism of the study is that:
- I see no rationale for doing such a trial,
- there is no evidence to suggest that homeopathy might prevent recurrent urinary tract infections,
- there is compelling evidence that homeopathic remedies are placebos,
- the study thus compares one placebo with another placebo (in fact, it is a classic example of what my late friend Harriet Hall would have called TOOTH FAIRY SCIENCE),
- therefore, its results will show no difference between the 2 groups (provided the trial was conducted without bias),
- if that is true, enthusiastic homeopaths will claim that the homeopathic verum was inadequate (e.g. because the homeopaths prescribing the verum did not or could not do their job properly),
- when that happens, they will therefore not stop claiming that homeopathy can reduce the over-prescribing of antibiotics;
- that means we will be exactly where we were before the trial.
In other words, the study will turn out to be a waste of 709,480.75 Euros. To express it as I did in my previous post: the Bavarian government has gone barmy!
This study examined the incidence and severity of adverse events (AEs) of patients receiving chiropractic spinal manipulative therapy (SMT), with the hypothesis that < 1 per 100,000 SMT sessions results in a grade ≥ 3 (severe) AE. A secondary objective was to examine independent predictors of grade ≥ 3 AEs.
The researchers retrospectively identified patients with SMT-related AEs from January 2017 through August 2022 across 30 chiropractic clinics in Hong Kong. AE data were extracted from a complaint log, including solicited patient surveys, complaints, and clinician reports, and corroborated by medical records. AEs were independently graded 1–5 based on severity (1-mild, 2-moderate, 3-severe, 4-life-threatening, 5-death).
Among 960,140 SMT sessions for 54,846 patients, 39 AEs were identified, two were grade 3, both of which were rib fractures occurring in women age > 60 with osteoporosis, while none were grade ≥ 4, yielding an incidence of grade ≥ 3 AEs of 0.21 per 100,000 SMT sessions (95% CI 0.00, 0.56 per 100,000). There were no AEs related to stroke or cauda equina syndrome. The sample size was insufficient to identify predictors of grade ≥ 3 AEs using multiple logistic regression.
The authors concluded that, in this study, severe SMT-related AEs were reassuringly very rare.
This is good news for all patients who consult chiropractors. However, there seem to be several problems with this study:
- Data originated from 30 affiliated chiropractic clinics with 38 chiropractors (New York Chiropractic & Physiotherapy Center, EC Healthcare, Hong Kong). These clinics are integrated into a larger healthcare organization, including several medical specialties and imaging and laboratory testing centers that utilize a shared medical records system. The 38 chiropractors represent only a little more than 10% of all chiropractors working in Hanh Kong and are thus not representative of all chiropractors in that region. Is it possible that the participating chiropractors were better trained, more gentle, or more careful than the rest?
- Data regarding AEs was obtained from a detailed complaint log that was routinely aggregated from several sources by a customer service department. One source of AEs in this log was a custom survey administered to patients after their 1st, 2nd, and 16th visits. Additional AEs derived from follow-up phone calls by a personal health manager. This means that not all AE might have been noted. Some patients might not have complained, others might have been too ill to do so. And, of course, dead patients cannot complain. The authors state that “the response to the SMS questionnaire was low. It is possible that severe AEs occurred but were not reported or recorded through these or other methods of ascertainment”.
- The 39 AEs potentially related to chiropractic SMT included increased symptoms related to the patient’s chief complaint (n = 28), chest pain without a fracture on imaging (n = 4), jaw pain (n = 3), rib fracture confirmed by imaging (n = 2), headache and dizziness without evidence of stroke (n = 1), and new radicular symptoms (n = 1). Of the 39 AEs, grade 2 were most common (n = 32, 82%), followed by grade 1 (n = 5, 13%), and grade 3 (n = 2, 5%). There were no cases of stroke, transient ischemic attack (TIA), vertebral or carotid artery dissection, cauda equina syndrome, or spinal fracture. Yet, headache and dizziness could be signs of a TIA.
- Calculating the rate of AEs per SMT session might be misleading and of questionable value. Are incidence rates of AEs not usually expressed as AE/patient? In this case, the % rate would be almost 20 times higher.
Altogether, this is a laudable effort to generate evidence for the risks of SMT. The findings seem reassuring but sadly they are not fully convincing.
The McTimoney College of Chiropractic just announced that it has established a new four-year program in veterinary chiropractic for college students:
It means that those without a prior degree can undertake the training and education necessary to enter this coveted career. To date, animal chiropractors were required to have a prior qualification in human chiropractic or a degree in the relevant sciences.
Applications for the new program are being accepted from September 2023. Students will attend Abingdon-based University, Oxford, and a variety of practical locations, enabling the development of academic knowledge and the application of practical skills together . Modules include anatomy and physiology, veterinary science, practice and professionalism, and clinical skills, with a research dissertation running over the four-year course.
University director Christina Cunliffe said the new program was an exciting step in the development of chiropractic care for animals.
“Building on our decades of experience graduating confident, competent, and highly-skilled animal chiropractors, now is the time to open up this exciting career opportunity to college students.”
For the past 50 years, McTimoney College of Chiropractic has been training and educating human chiropractors to the highest regulatory standards. Over the past 20 years, animal chiropractic has developed to meet the requirements for this gentle, holistic treatment in the veterinary world.
Prospective students are invited to a Open House at McTimoney College of Chiropractic in Abingdon on February 16.
McTimoney Chiropractic for Animals identifies areas of stiffness, asymmetry, and poor range of motion within the skeletal system, particularly the spine and pelvis. This affects the muscles that surround these structures, as well as the nerve impulses that pass from the central nervous system to the periphery of the body. The adjustments are very light and fast, stimulating an instant response in the affected soft tissues and joints, promoting relaxation of muscle spasms, improving nerve function, and helping the skeletal structure regain better symmetry and movement again.
In many cases, animals suffer from underlying conditions such as arthritic changes or degenerative diseases that force them to compensate in their posture and movement in an attempt to remain comfortable. However, these offsets become increasingly entrenched and can be painful or uncomfortable, requiring chiropractic care to provide some relief. In other cases, the animals are working hard or competing and as such accumulate tension and asymmetries due to the demands of their work. Once again, chiropractic care helps relieve pain and promote performance, whether it’s faster speeds over hurdles for racehorses and events, better jumping style in showjumpers, or more extravagant movements for dressage stars.
Two recent graduates of the school’s Master of Animal Handling (Chiropractic) program did not hesitate to recommend the university. Natalie McQuiggan said that she had wanted to do McTimoney Chiropractic from a very young age, “but the process of doing it always seemed really daunting.
“But from the start, the staff and teachers were lovely and welcoming, and queries were answered promptly. I have really enjoyed my two years in the Master of Animal Handling (Chiropractic) program and would recommend anyone thinking of doing it to just do it.”
Pollyanna Fitzgerald said the university offered a supportive and welcoming learning environment, allowing her to grow and develop as a student and future professional. “There is always someone to talk to and offer encouragement when needed. As a student I have learned a lot and have been encouraged to believe in myself and it has been a wonderful place to learn.”
A free webinar, McTimoney’s Animal Chiropractic as a Careeron January 24 at 7:30 p.m. (GMT), is open to those who wish to learn more about the McTimoney technique and its application, and the training paths available to those interested in becoming a McTimoney Animal Chiropractor.
________________________
I think this announcement is puzzling on several levels:
- I was unable to find an ‘Abingdon-based University, Oxford’; could it be this institution that is a college and not a university?
- Christina Cunliffe seems to be (or has been?) affiliated with the McTimoney College of Chiropractic which is a bit odd, in my opinion.
- The college does not have ‘decades of experience’; it was founded only in 2001.
- Most importantly, I am unable to find a jot of good evidence that veterinary chiropractic is effective for any condition (see also here, here, and here). In case anyone is aware of any, please let me know. I’d be delighted to revise my judgment.
If I am right, the new course could be a fine example of quackademia where students are ripped off and taught to later rip off the owners of animals after the academically trained quacks have mistreated them.
Migraines are common headache disorders and risk factors for subsequent strokes. Acupuncture has been widely used in the treatment of migraines; however, few studies have examined whether its use reduces the risk of strokes in migraineurs. This study explored the long-term effects of acupuncture treatment on stroke risk in migraineurs using national real-world data.
A team of Taiwanese researchers collected new migraine patients from the Taiwan National Health Insurance Research Database (NHIRD) from 1 January 2000 to 31 December 2017. Using 1:1 propensity-score matching, they assigned patients to either an acupuncture or non-acupuncture cohort and followed up until the end of 2018. The incidence of stroke in the two cohorts was compared using the Cox proportional hazards regression analysis. Each cohort was composed of 1354 newly diagnosed migraineurs with similar baseline characteristics. Compared with the non-acupuncture cohort, the acupuncture cohort had a significantly reduced risk of stroke (adjusted hazard ratio, 0.4; 95% confidence interval, 0.35–0.46). The Kaplan–Meier model showed a significantly lower cumulative incidence of stroke in migraine patients who received acupuncture during the 19-year follow-up (log-rank test, p < 0.001).
The authors concluded that acupuncture confers protective benefits on migraineurs by reducing the risk of stroke. Our results provide new insights for clinicians and public health experts.
After merely 10 minutes of critical analysis, ‘real-world data’ turn out to be real-bias data, I am afraid.
The first question to ask is, were the groups at all comparable? The answer is, NO; the acupuncture group had
- more young individuals;
- fewer laborers;
- fewer wealthy people;
- fewer people with coronary heart disease;
- fewer individuals with chronic kidney disease;
- fewer people with mental disorders;
- more individuals taking multiple medications.
And that are just the variables that were known to the researcher! There will be dozens that are unknown but might nevertheless impact on a stroke prognosis.
But let’s not be petty and let’s forget (for a minute) about all these inequalities that render the two groups difficult to compare. The potentially more important flaw in this study lies elsewhere.
Imagine a group of people who receive some extra medical attention – such as acupuncture – over a long period of time, administered by a kind and caring therapist; imagine you were one of them. Don’t you think that it is likely that, compared to other people who do not receive this attention, you might feel encouraged to look better after your health? Consequently, you might do more exercise, eat more healthily, smoke less, etc., etc. As a result of such behavioral changes, you would be less likely to suffer a stroke, never mind the acupuncture.
SIMPLE!
I am not saying that such studies are totally useless. What often renders them worthless or even dangerous is the fact that the authors are not more self-critical and don’t draw more cautious conclusions. In the present case, already the title of the article says it all:
Acupuncture Is Effective at Reducing the Risk of Stroke in Patients with Migraines: A Real-World, Large-Scale Cohort Study with 19-Years of Follow-Up
My advice to researchers of so-called alternative medicine (SCAM) and journal editors publishing their papers is this: get your act together, learn about the pitfalls of flawed science (most of my books might assist you in this process), and stop misleading the public. Do it sooner rather than later!
Chronic kidney disease is common, often progressive, and difficult to treat or prevent. Effective interventions would therefore be more than welcome. This paper explored the relation of habitual fish oil use with the risk of chronic kidney diseases (CKD).
A total of 408,023 participants (54.2% female) without prior CKD and with completed information regarding their consumption of major food groups and fish oil in the UK Biobank were enrolled. Fish oil use and dietary intakes were assessed by touch screen questionnaire and food frequency questionnaire, respectively. Incident CKD was recorded from hospital inpatient records.
At baseline, 128,843 (31.6%) participants reported taking fish oil supplements. During a median follow-up period of 12.0 years, a total of 10,782 (2.6%) participants developed CKD. With adjustments for important confounders, habitual fish oil use was associated with a significantly lower hazard of incident CKD (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.87-0.95), compared with non-use. Consistently, participants reporting ≥2 servings/week of oily fish (HR, 0.86; 95% CI, 0.79-0.94) and nonoily fish (HR, 0.86; 95% CI, 0.77-0.97) consumption had a lower hazard of incident CKD compared to those reporting no consumption ever. Additionally, among the 97,914 participants with data on plasma fatty acid, there were significant inverse relationships of plasma omega-3 polyunsaturated fatty acid (PUFA) (per SD increment, HR, 0.89, 95% CI, 0.84-0.94) and eicosatetraenoic acid (per SD increment, HR, 0.91, 95% CI, 0.87-0.96) with incident CKD.
The authors concluded that habitual fish oil use was associated with a lower hazard of CKD, which was further confirmed by the consistent inverse relations between fish consumption and circulating omega-3 PUFA concentration with incident CKD.
I like this paper! It shows in an exemplary fashion how to interpret an association between two variables: fish oil consumption does not necessarily CAUSE the lower risk, it is merely associated with it and there might be a number of non-causal explanations for the link. Whether there is a true cause-effect relationship needs to be investigated in further, differently designed studies. The present paper does not overstate its conclusions but it is nevertheless important, as it hopefully will prompt others to clarify the crucial issue of causality.
Wouldn’t it be nice, if researchers of so-called alternative medicine (SCAM) finally learned this simple lesson?
On 20/1/2023, I conducted multiple Medline searches aimed at generating a rough idea about which areas of so-called alternative medicine (SCAM) are currently more research active than others. I searched for:
- the topic in question
- clinical trial
- publication in 2023
Here are my findings (subject area and the number of hits):
- TCM 56
- dietary supplements 47
- acupuncture 34
- integrative medicine 27
- mindfulness 26
- herbal medicine 23
- massage 10
- aromatherapy 2
- hypnotherapy 2
- osteopathy 2
- tai chi 2
- chiropractic 1
- homeopathy 0
- iridology 0
- naturopathy 0
- Reiki 0
Several caveats must be considered, of course: The searches do not include all SCAMs. The results are not precise and most of the retrieved articles are not really clinical trials (in fact, only a minority are). The numbers are low because I deliberately did this exercise early in the year.
Yet, the findings do, I think, give an indication as to the current state of SCAM research and indicate which areas are more research active than others. To put the numbers in perspective, here are a few conventional therapies for which I searched on the same day and in the same manner:
- pharmacology 539
- physiotherapy 162
- psychiatry 239
- surgery 879
I think this makes one point fairly clear: SCAM is not an impressively research-active area. Another point stems from looking at the individual articles. TCM and acupuncture articles are almost exclusively authored by Chinese researchers. While this might not be surprising, the fact that herbal medicine is similar did amaze me; about half of the papers in this category are by Chinese authors. Essentially, this suggests that more than half of the SCAM articles currently originate from China. Considering the concerns one must have about Chinese SCAM research (see for instance here and here), do you think this finding might be worrying?
The far greater worry, I feel, is the attitude of the SCAM researchers publishing their work. Glancing at these papers I did not get the impression that many approached their subject critically, In fact, most of the papers looked to me overtly promotional and of poor quality. For instance, I did not see a single paper assessing the risks of SCAM which arguably is the most important issue in SCAM research. I admit that these concerns cannot be addressed by the above simple head count; they are best dealt with by critically analyzing individual studies – a task I regularly try to tackle on this blog
About a century ago, Royal Raymond Rife developed special microscopes and claimed he could visualize living microorganisms, including viruses too small to be seen with any other existing technology, via the color of auras emitted as they vibrated. In 1961, he explained this as follows: “A special risley prism which works on a counter rotation principle selects a portion of the light frequency which illuminates these viruses in their own characteristic chemical colors by emission of coordinative light frequency and the viruses become readily identifiable by the colors revealed on observation.”. The principles and alleged function of these microscopes have never been validated, and they have never been adopted for use.
Rife went on to postulate that the microorganisms he was seeing were involved in human diseases, including cancer . He also invented a machine that he claimed could transmit radio frequency energy into a person and vibrate these microorganisms at a “mortal oscillatory rate”, thereby killing them and improving the disease they were causing. The concept that diseases can be cured by radio frequency energy, originally proposed by Albert Abrams and referred to as ‘radionics’, was later investigated and disproven. Nonetheless, there remain enthusiasts who believe in Rife’s work, claim it was suppressed as part of an elaborate conspiracy. and continue to sell energy-transmitting devices and cures.
Rife machines (also called a Rife frequency generator.) produce low electromagnetic energy waves. These waves are similar to radio waves. Supporters of the treatment claim that the Rife machine can treat different conditions including cancer. There is no reliable evidence that the Rife machine works as a cure for cancer.
The Rife machine produces low-energy waves, also called radiofrequency electromagnetic fields. They have low energy compared to x-rays or radiotherapy.
Here is what proponents of the Rife therapy say:
… Although no official health claims are made for Rife therapy, testimonials from many countries point to its efficacy in the support of the body in maintaining or regaining good, natural health. A good Rife machine normally contains all of the original Royal Rife frequencies plus others that have been researched and utilised over the years.
WHAT IS THE PROCEDURE?
In most Rife sessions the client is seated. They have their feet on footplate electrodes and in their lap they hold in their hands plasma tubes. Thus they get the frequencies in normal form through the feet and in radio wave form through their hands. There are variations on this but this is the basic set up.
Some practitioners will occasionally employ something called a Beam Ray Tube. This is essentially a large plasma tube on a stand that plugs into the machine. The client just sits in front of it, about 3 feet away, while the frequencies are generated. In this instance the client does not have to hold anything or have their feet on footplates.
HOW LONG DO SESSIONS LAST?
The length of a session varies, depending on what is being addressed. Any session would be a minimum of 30 minutes but in serious or chronic conditions can last over 2 hours, occasionally more. However, clients can take breaks during the therapy.
HOW FREQUENT ARE TREATMENTS?
Once a week or once a fortnight is a common pattern of treatments. But in the case of more frequent sessions a minimum of 48 hours should be left between therapy. The duration of treatments varies on the condition being addressed. Sometimes it’s just a few visits…for conditions like Lyme Disease the treatments are ongoing for well over a year. The practitioner will answer your specific questions on this.
There are also frequencies to support regeneration and boost functions such as the immune system, the adrenals and several others.
ARE THERE ANY CONTRAINDICATIONS?
Rife therapy is not suitable for people with pacemakers or similar devices. It should not be given to children under 4 years of age. If a client is undergoing radiotherapy or frequency therapy for kidney stones etc there should should be no Rife sessions administered during these periods.
The day after some sessions a client may occasionally get a Herxheimer’s reaction. This is a feeling of tiredness, almost as if one is about to go down with flu. It was named after Dr Herxheimer who, along with one other doctor, discovered that when the liver and kidneys etc get overworked in disposing of waste products, this phenomena happens. The answer is just to drink lots of fluid to help the body dispose of the cells or toxins that have been eliminated by the Rife session. The day after that, the client is back to normal and usually feeling better than before the session.
I think that such promotional texts could and should be much shorter, more truthful, and hugely more informative, e.g.:
Rife therapy is not biologically plausible, has never been shown to be effective for any condition, might have adverse effects, and is not cheap. Therefore, we have a responsibility to warn consumers and patients not to use it.
In this study, the impact of a multimodal integrative oncology pre- and intraoperative intervention on pain and anxiety among patients undergoing gynecological oncology surgery was explored.
Study participants were randomized into three groups:
- Group A received preoperative touch/relaxation techniques, followed by intraoperative acupuncture, plus standard care;
- Group B received preoperative touch/relaxation only, plus standard care;
- Group C (the control group) received standard care.
Pain and anxiety were scored before and after surgery using the Measure Yourself Concerns and Wellbeing (MYCAW) and Quality of Recovery (QOR-15) questionnaires, using Part B of the QOR to assess pain, anxiety, and other quality-of-life parameters.
A total of 99 patients participated in the study: 45 in Group A, 25 in Group B, and 29 in Group C. The three groups had similar baseline demographic and surgery-related characteristics. Postoperative QOR-Part B scores were significantly higher in the treatment groups (A and B) when compared with controls (p = .005), including for severe pain (p = .011) and anxiety (p = .007). Between-group improvement for severe pain was observed in Group A compared with controls (p = .011). Within-group improvement for QOR depression subscales was observed in only the intervention groups (p <0.0001). Compared with Group B, Group A had better improvement of MYCAW-reported concerns (p = .025).
The authors concluded that a preoperative touch/relaxation intervention may significantly reduce postoperative anxiety, possibly depression, in patients undergoing gynecological oncology surgery. The addition of intraoperative acupuncture significantly reduced severe pain when compared with controls. Further research is needed to confirm these findings and better understand the impact of intraoperative acupuncture on postoperative pain.
Regular readers of my blog know only too well what I am going to say about this study.
Imagine you have a basket full of apples and your friend has the same plus a basket full of pears. Who do you think has more fruit?
Dumb question, you say?
Correct!
Just as dumb, it seems, as this study: therapy A and therapy B will always generate better outcomes than therapy B alone. But that does not mean that therapy A per se is effective. Because therapy A generates a placebo effect, it might just be that it has no effect beyond placebo. And that acupuncture can generate placebo effects has been known for a very long time; to verify this we need no RCT.
As I have so often pointed out, the A+B versus B study design never generates a negative finding.
This is, I fear, precisely the reason why this design is so popular in so-called alternative medicine (SCAM)! It enables promoters of SCAM (who are not as dumb as the studies they conduct) to pretend they are scientists testing their therapies in rigorous RCTs.
The most disappointing thing about all this is perhaps that more and more top journals play along with this scheme to mislead the public!
The impact of drug-induced liver injury (DILI) on patients with chronic liver disease (CLD) is unclear. There are few reports comparing DILI in CLD and non-CLD patients. In this study, the researchers aimed to determine the incidence and outcomes of DILI in patients with and without CLD.
They collected data on eligible individuals with suspected DILI between 2018 and 2020 who were evaluated systematically for other etiologies, causes, and the severity of DILI. They compared the causative agents, clinical features, and outcomes of DILI among subjects with and without CLD who were enrolled in the Thai Association for the Study of the Liver DILI registry. Subjects with definite, or highly likely DILI were included in the analysis.
The researchers evaluated the causal relationship between the clinical pattern of liver injury and the suspected drugs or SCAM products with the Roussel Uclaf Causality Assessment Method (RUCAM) system. RUCAM is a validated and established tool to quantitatively assess causality in cases of suspected DILI and/or SCAM product-induced liver injury. They also used the Clinical Assessment of Causality Scale to assess the association as definite (>95% likelihood), highly likely (75–95%), probable (50–74%), possible (25–49%) or unlikely (<25%).
A total of 200 subjects diagnosed with DILI were found in the registry. Of those, 41 had CLD and 159 had no evidence of CLD. So-called alternative medicine (SCAM) products were identified as the most common class of DILI agents. Approximately 59% of DILI in the CLD and 40% in non-CLD group were associated with SCAM use. Individuals with pre-existing CLD had similar severity including mortality. Twelve patients (6%) developed adverse outcomes related to DILI including seven (3.5%) deaths and five (2.5%) with liver failure. Mortality was 4.88% in CLD and 3.14% in non-CLD subjects over median periods of 58 (8-106) days and 22 (1-65) days, respectively.
The authors concluded that, in this liver disease registry, the causes, clinical presentation, and outcomes of DILI in subjects with CLD and without CLD patients were not different. Further study is required to confirm our findings.
Consumers often prefer SCAM to conventional medicine because SCAM is viewed as gentle and safe. The notions are that they
- are natural and therefore harmless;
- have been in use for ages and thus have stood the test of time.
Readers of this blog will appreciate that both notions are, in fact, fallacies:
- appeal to nature;
- appeal to tradition.
This new paper is an impressive reminder that SCAM’s reputation as a safe option is not justified, and that SCAM relies more on fallacies than on facts.
