This systematic review aimed to identify and explore published studies on the health, wellbeing and economic impact of retreat experiences. Three electronic databases were searched for residential retreat studies published in English. Studies were included, if they involved an intervention program in a residential setting of one or more nights, and included before-and-after data related to the health of participants.
A total of 23 studies including 8 randomised controlled trials, 6 non-randomised controlled trials and 9 longitudinal cohort studies met the inclusion criteria. These studies included a total of 2592 participants from diverse geographical and demographic populations and a great heterogeneity of outcome measures, with 7 studies examining objective outcomes such as blood pressure or biological makers of disease, and 16 studies examining subjective outcomes that mostly involved self-reported questionnaires on psychological and spiritual measures.
All studies reported post-retreat health benefits ranging from immediately after to five-years post-retreat. Study populations varied widely and most studies had small sample sizes, poorly described methodology and little follow-up data, and no studies reported on health economic outcomes or adverse effects, making it difficult to make definite conclusions about specific conditions, safety or return on investment.
The authors concluded that health retreat experiences appear to have health benefits that include benefits for people with chronic diseases such as multiple sclerosis, various cancers, HIV/AIDS, heart conditions and mental health. Future research with larger numbers of subjects and longer follow-up periods are needed to investigate the health impact of different retreat experiences and the clinical populations most likely to benefit. Further studies are also needed to determine the economic benefits of retreat experiences for individuals, as well as for businesses, health insurers and policy makers.
In the article, the authors also state that the findings from the reviewed studies suggest there are many positive health benefits from retreat experiences that includes improvements in both subjective and objective measures… The results from the most rigorous studies that used randomized controlled designs were consistent with less rigorous studies and suggest that retreat experiences can produce benefits that include positive changes in metabolic and neurological pathways, loss of weight, blood pressure and abdominal girth, reduction in health symptoms and improvements in quality of life and subjective wellbeing.
As it happens, we have discussed one of their ‘most rigorous’ RCTs on this blog. Here is what I wrote about it when it was first published:
The ‘study‘ in question allegedly examined the effects of a comprehensive residential mind–body program on well-being. The authors describe it as “a quasi-randomized trial comparing the effects of participation in a 6-day Ayurvedic system of medicine-based comprehensive residential program with a 6-day residential vacation at the same retreat location.” They included 69 healthy women and men who received the Ayurvedic intervention addressing physical and emotional well-being through group meditation and yoga, massage, diet, adaptogenic herbs, lectures, and journaling. Key components of the program include physical cleansing through ingestion of herbs, fiber, and oils that support the body’s natural detoxification pathways and facilitate healthy elimination; two Ayurvedic meals daily (breakfast and lunch) that provide a light plant-based diet; daily Ayurvedic oil massage treatments; and heating treatments through the use of sauna and/or steam. The program includes lectures on Ayurvedic principles and lifestyle as well as lectures on meditation and yoga philosophy. The study group also participated in twice-daily group meditation and daily yoga and practiced breathing exercises (pranayama) as well as emotional expression through a process of journaling and emotional support. During the program, participants received a 1-hour integrative medical consultation with a physician and follow-up with an Ayurvedic health educator.
The control group simply had a vacation without any of the above therapies in the same resort. They were asked to do what they would normally do on a resort vacation with the additional following restrictions: they were asked not to engage in more exercise than they would in their normal lifestyle and to refrain from using La Costa Resort spa services. They were also asked not to drink ginger tea or take Gingko biloba during the 2 days before and during the study week.
Recruitment was via email announcements on the University of California San Diego faculty and staff and Chopra Center for Wellbeing list-servers. Study flyers stated that the week-long Self-Directed Biological Transformation Initiative (SBTI) study would be conducted at the Chopra Center for Wellbeing, located at the La Costa Resort in Carlsbad, California, in order to learn more about the psychosocial and physiologic effects of the 6-day Perfect Health (PH) Program compared with a 6-day stay at the La Costa Resort. The study participants were not blinded, and site investigators and study personnel knew to which group participants were assigned.
Participants in the Ayurvedic program showed significant and sustained increases in ratings of spirituality and gratitude compared with the vacation group, which showed no change. The Ayurvedic participants also showed increased ratings for self-compassion as well as less anxiety at the 1-month follow-up.
The authors arrived at the following conclusion: Findings suggest that a short-term intensive program providing holistic instruction and experience in mind–body healing practices can lead to significant and sustained increases in perceived well-being and that relaxation alone is not enough to improve certain aspects of well-being.
This ‘study’ had ethical approval from the University of California San Diego and was supported by the Fred Foundation, the MCJ Amelior Foundation, the National Philanthropic Trust, the Walton Family Foundation, and the Chopra Foundation. The paper’s first author is director of research at the Chopra Foundation… Just for the record, let me formulate a short conclusion that actually fits the data from this ‘study’: Lots of TLC, attention and empathy does make some people feel better…
END OF QUOTE FROM MY OWN POST
The subject of health retreats could be relevant and important. Educating people and teaching them the essentials about healthy life-styles is potentially a good thing. It could well turn out that health retreats benefit many individuals, while saving money for society.
Yet, do we need all sorts of quackery for achieving this aim?
No, we don’t!
A rational programme would need to teach and motivate people about diet, weight control, smoking cessation, regular sleep, relaxation, exercise, etc. It could prevent disease and save funds. This approach has existed in Europe long before the US ‘New Agers’ with their flimflam jumped on this bandwagon. Health education is a good idea, but it does not require the use of alternative therapies or luxury retreats.
As it turns out, the new systematic review is a disappointment. It fails to stress that no firm conclusions can be drawn from flimsy data and degenerates into little more than an embarrassing advertisement for Deepak Chopra’s and similar entrepreneurs’ money-making retreats. It totally ignores the sizable body of Non-English literature on the subject, and is focussed on promoting fashionable retreats and wellness centres in the US and Australia.
To be fair to the authors, they almost admit as much when they state: “Competing interests: MC is a board member of the Global Wellness Summit and has previously been a paid presenter at the Gwinganna Health Retreat. RMIT University has received donations from Danubius Hotel Group, Lapinha, Sunswept Resorts, Sheenjoy and The Golden Door for ongoing retreat research.”
I rest my case.
Can conventional therapy (CT) be combined with herbal therapy (CT + H) in the management of Alzheimer’s disease (AD) to the benefit of patients? This was the question investigated by Chinese researchers in a recent retrospective cohort study funded by grants from China Ministry of Education, National Natural Science Foundation of China, Beijing Municipal Science and Technology Commission, and Beijing Municipal Commission of Health and Family Planning.
In total, 344 outpatients diagnosed as probable dementia due to AD were collected, who had received either CT + H or CT alone. The GRAPE formula was prescribed for AD patients after every visit according to TCM theory. It consisted mainly (what does ‘mainly’ mean as a description of a trial intervention?) of Ren shen (Panax ginseng, 10 g/d), Di huang (Rehmannia glutinosa, 30 g/d), Cang pu (Acorus tatarinowii, 10 g/d), Yuan zhi (Polygala tenuifolia, 10 g/d), Yin yanghuo (Epimedium brevicornu, 10 g/d), Shan zhuyu (Cornus officinalis, 10 g/d), Rou congrong (Cistanche deserticola, 10 g/d), Yu jin (Curcuma aromatica, 10 g/d), Dan shen (Salvia miltiorrhiza, 10 g/d), Dang gui (Angelica sinensis, 10 g/d), Tian ma (Gastrodia elata, 10 g/d), and Huang lian (Coptis chinensis, 10 g/d), supplied by Beijing Tcmages Pharmaceutical Co., LTD. Daily dose was taken twice and dissolved in 150 ml hot water each time. Cognitive function was quantified by the mini-mental state examination (MMSE) every 3 months for 24 months.
The results show that most of the patients were initially diagnosed with mild (MMSE = 21-26, n = 177) and moderate (MMSE = 10-20, n = 137) dementia. At 18 months, CT+ H patients scored on average 1.76 (P = 0.002) better than CT patients, and at 24 months, patients scored on average 2.52 (P < 0.001) better. At 24 months, the patients with improved cognitive function (△MMSE ≥ 0) in CT + H was more than CT alone (33.33% vs 7.69%, P = 0.020). Interestingly, patients with mild AD received the most robust benefit from CT + H therapy. The deterioration of the cognitive function was largely prevented at 24 months (ΔMMSE = -0.06), a significant improvement from CT alone (ΔMMSE = -2.66, P = 0.005).
The authors concluded that, compared to CT alone, CT + H significantly benefited AD patients. A symptomatic effect of CT + H was more pronounced with time. Cognitive decline was substantially decelerated in patients with moderate severity, while the cognitive function was largely stabilized in patients with mild severity over two years. These results imply that Chinese herbal medicines may provide an alternative and additive treatment for AD.
Conclusions like these render me speechless – well, almost speechless. This was nothing more than a retrospective chart analysis. It is not possible to draw causal conclusions from such data.
Because of a whole host of reasons. Most crucially, the CT+H patients were almost certainly a different and therefore non-comparable population to the CT patients. This flaw is so elementary that I need to ask, who are the reviewers letting such utter nonsense pass, and which journal would publish such rubbish? In fact, I can be used for teaching students why randomisation is essential, if we aim to find out about cause and effect.
Ahhh, it’s the BMC Complement Altern Med! I think the funders, editors, reviewers, and authors of this paper should all go and hide in shame.
How often have we heard the claim from proponents of alternative medicine that one strength of their approach is disease prevention (see for instance my previous post or this, this and this) and that conventional medicine neglects prevention almost completely? Such claims annoy me because they are demonstrably false.
I know, to some readers, this may seem like a bold statement; let me therefore try to justify it.
- So far, I have seen no good evidence that any alternative therapy might be effective in preventing any disease.
- Practically everything we know today about disease prevention originates from conventional medicine and science.
- There are thousands of papers that address prevention and, as far as I can see, they all originate from the realm of conventional medicine. Below is a list of just 7 recent reviews on the subject.
This paper is an update of the evidence for exercise as a prevention of heart failure. It concluded that exercise provides protective benefit in preventing HF (primary prevention). With HF present: exercise improvement with training provides benefits in HF (secondary prevention). The prediction of future in HF patients: exercise impairment, as a leading characteristic of HF, is used as a prognostic factor.
The aim of this review was to update evidence for the US Preventive Services Task Force on the benefits and harms of hormone therapy in reducing risks for chronic conditions. The authors found that hormone therapy for the primary prevention of chronic conditions in menopausal women is associated with some beneficial effects but also with a substantial increase of risks for harms. The available evidence regarding benefits and harms of early initiation of hormone therapy is inconclusive.
This paper reviewed the evidence for Implantable Cardiac Defibrillators (ICDs). The authors stated that individuals with stable ischemic heart disease (no recent myocardial infarction), especially those with inducible arrhythmias, seem to derive the highest mortality benefit from prophylactic ICD use.
These authors investigated whether neuromuscular and proprioceptive training is effective in preventing knee and anterior cruciate ligament (ACL) injuries. They concluded that neuromuscular and proprioceptive training appeared to decrease the incidence of injury to the knee and specifically the AC.
Other researchers summarized current evidence about real-world studies on apixaban for stroke prevention in atrial fibrillation. They concluded that the use of apixaban in real-life is associated with an overall similar effectiveness in reducing stroke and any thromboembolic events when compared with warfarin. A better safety profile was found with apixaban compared with warfarin, dabigatran, and rivaroxaban.
Finally, a review assessed the evidence of blood pressure (BP) lowering treatments as a means of reducing cardiovascular morbidity and mortality. The authors concluded that primary preventive BP lowering is associated with reduced risk for death and CVD if baseline SBP is 140 mm Hg or higher. At lower BP levels, treatment is not associated with any benefit in primary prevention but might offer additional protection in patients with CHD.
Testing preventative treatments is, of course, far from easy. Ideally, one would want to do an RCT, but often this is not possible, for instance, because the sample size would need to be prohibitively huge and the observation period prohibitively long (think of cholesterol-lowering for reducing cardiovascular risks, or smoking cessation for preventing cancer). Thus we rely frequently on other types of investigations such as epidemiological studies. This type of research is, however, rarely undertaken in alternative medicine, and when it does cover subjects related to this area, it is almost never done by proponents of alternative medicine.
The long and short of all this is depressingly simple: the often-heard claim that alternative medicine is strong on prevention is quite simply false. Proponents of alternative medicine like to talk about prevention (presumably because it is good for business), but when it comes to applying prevention and showing that their preventative interventions are effective, all this talk turns out to be little more than hot air.
I am sure – even hope – that some readers will disagree, and I look forward to their evidence proving me wrong.
This is a fascinating new review of upper neck manipulation. It raises many concerns that we, on this blog, have been struggling with for years. I take the liberty of quoting a few passages which I feel are important and encourage everyone to study the report in full:
The Minister of Health, Seniors and Active Living gave direction to the Health Professions Advisory Council (“the Council”) to undertake a review related to high neck manipulation.
Specifically, the Minister directed the Council to undertake:
1) A review of the status of the reserved act in other Canadian jurisdictions,
2) A literature review related to the benefits to patients and risks to patient safety associated with the procedure, and
3) A jurisprudence review or a review into the legal issues that have arisen in Canada with respect to the performance of the procedure that touch upon the risk of harm to a patient.
In addition, the Minister requested the Council to seek written input on the issue from:
- Manitoba Chiropractic Stroke Survivors
- Manitoba Chiropractic Association
- College of Physiotherapists of Manitoba
- Manitoba Naturopathic Association
- College of Physicians and Surgeons of Manitoba
- other relevant interested parties as determined by the Council
… The review indicated that further research is required to:
- strengthen evidence for the efficacy of cervical spinal manipulations (CSM) as a treatment for neck pain and headache, “as well as for other indications where evidence currently does not exist (i.e., upper back and should/arm pain, high blood pressure, etc.)”
- establish safety and efficacy of CSM in infants and children
- assess the risk versus benefit in consideration of using HVLA cervical spine manipulation, which also involve cost-benefit analyses that compare CSM to other standard treatments.
… the performance of “high neck manipulation” or cervical spine manipulation does present a risk of harm to patients. This risk of harm must be understood by both the patient and the practitioner.
Both the jurisprudence review and the research literature review point to the need for the following actions to mitigate the risk of harm associated with the performance of cervical spine manipulation:
- Action One: Ensure that the patient provides written informed consent prior to initiating treatment which includes a discussion about the risk associated with cervical spine manipulation.
- Action Two: Provide patients with information to assist in the early recognition of a serious adverse event.
It was based on a design-based logistic regression analysis of the European Social Survey (ESS), Round 7. The researchers distinguished 4 modalities: manual therapies, alternative medicinal systems, traditional Asian medical systems and mind-body therapies.
In total, 25.9% of the general population had used at least one of these therapies during the last 12 months which was around one-third of the proportion of those who had visited a general practitioner (76.3%). Typically, only one treatment had been used, and it was used more often as complementary rather than alternative treatment. The usage varied greatly by country (see Table 1 below). Compared to those in good health, the use of CAM was two to fourfold greater among those with health problems. The health profiles of users of different CAM modalities varied. For example, back or neck pain was associated with all types of CAM, whereas depression was associated only with the use of mind-body therapies. Individuals with difficult to diagnose health conditions were more inclined to utilize CAM, and CAM use was more common among women and those with a higher education. Lower income was associated with the use of mind-body therapies, whereas the other three CAM modalities were associated with higher income.
The authors concluded that help-seeking differed according to the health problem, something that should be acknowledged by clinical professionals to ensure safe care. The findings also point towards possible socioeconomic inequalities in health service use.
As I said, this is one of the rare surveys that is worth studying in some detail. This is mainly because it is rigorous and its results are clearly presented. Much of what it reports has been known before (for instance, we showed that the use of CAM in the UK was 26% which ties in perfectly with the 21% figure considering that here only 4 CAMs were included), but it is undoubtedly valuable to see it confirmed based on sound methodology.
Apart of what the abstract tells us, there are some hidden gems from this paper:
- 8% of CAM users had used CAM exclusively (alternative use), without any visits to biomedical professionals in the last 12 months. This may look like a low figure, but I would argue that it is worryingly high considering that alternative usage of CAM has the potential to hasten patients’ deaths.
- The most frequently used CAM treatment was massage therapy, used by 11.9% of the population, followed by homeopathy (5.7%), osteopathy (5.2%), herbal treatments (4.6%), acupuncture (3.6%), chiropractic (2.3%), reflexology (1.7%) and spiritual healing (1.3%). Other modalities (Chinese medicine, acupressure and hypnotherapy) were used by around by 1% or less. The figure for homeopathy is MUCH smaller that the ones homeopaths want us to believe.
- About 9% of healthy survey-participants had used at least one of the CAM modalities during the last 12 months. One can assume that this usage was mostly for disease-prevention. But there is no good evidence for CAM to be effective for this purpose.
- The highest ORs for the use of Traditional Asian Medical Systems were found in Denmark, Switzerland and Israel, followed by Austria, Norway and Sweden. The highest OR for the use of Alternative Medical Systems was found in Lithuania, while manual therapies were most commonly used in Finland, Austria, Switzerland, Germany and Denmark. Moreover, Denmark, Ireland, Slovenia and Lithuania had the highest ORs for using mind-body therapies. France, Spain and Germany presented a common pattern, with relatively similar use of the different modalities. Poland and Hungary had low ORs for use of the different CAM modalities.
But by far the nicest gem, however, comes from my favourite source of misinformation on matters of health, WDDTY. They review the new survey and state this: The patients are turning to alternatives for a range of chronic conditions because they consider the conventional therapy to be inadequate, the researchers say. Needless to point out that this is not a theme that was addressed by the new survey, and therefore its authors also do not draw this conclusion.
I just came across a new article entitled ” Vaccinated children four times more likely to suffer from ADHD, autism“. It was published in WDDTY, my favourite source of misleading information. Here it is:
Vaccinated children are nearly four times more likely to suffer from learning disabilities, ADHD and autism, a major new study has discovered—and they are six times more likely to suffer from one of these neuro-developmental problems if they were also born prematurely.
The vaccinated child is also more likely to suffer from otitis media, the ear infection, and nearly six times more likely to contract pneumonia.
But the standard childhood vaccines do at least do their job: the vaccinated child is nearly eight times less likely than the unvaccinated to develop chicken pox, and also less likely to suffer from whooping cough (pertussis).
Researchers from Jackson State University are some of the first to look at the long-term effects of vaccination. They monitored the health of 666 children for six years from the time they were six—when the full vaccination programme had been completed—until they were 12. All the children were being home-schooled because it was one of the few communities where researchers could find enough unvaccinated children for comparison; 261 of the children hadn’t been vaccinated and 208 hadn’t had all their vaccinations, while 197 had received the full 48-dose course.
The vaccinated were more likely to suffer from allergic rhinitis, such as hay fever, eczema and atopic dermatitis, learning disability, ADHD (attention-deficit, hyperactive disorder), and autism. The risk was lower among the children who had been partially vaccinated.
Vaccinated children were also more likely to have taken medication, such as an antibiotic, or treatment for allergies or for a fever, than the unvaccinated.

I looked up the original study to check and found several surprises.
The first surprise was that the study was called a ‘pilot’ by its authors, even in the title of the paper: “Pilot comparative study on the health of vaccinated and unvaccinated 6- to 12-year-old U.S. children.”
The second surprise was that even the authors admit to important limitations of their research:
We did not set out to test a specific hypothesis about the association between vaccination and health. The aim of the study was to determine whether the health outcomes of vaccinated children differed from those of unvaccinated homeschool children, given that vaccines have nonspecific effects on morbidity and mortality in addition to protecting against targeted pathogens . Comparisons were based on mothers’ reports of pregnancy-related factors, birth histories, vaccinations, physician-diagnosed illnesses, medications, and the use of health services. We tested the null hypothesis of no difference in outcomes using chi-square tests, and then used Odds Ratios and 96% Confidence Intervals to determine the strength and significance of the association…
What credence can be given to the findings? This study was not intended to be based on a representative sample of homeschool children but on a convenience sample of sufficient size to test for significant differences in outcomes. Homeschoolers were targeted for the study because their vaccination completion rates are lower than those of children in the general population. In this respect our pilot survey was successful, since data were available on 261 unvaccinated children…
Mothers’ reports could not be validated by clinical records because the survey was designed to be anonymous. However, self-reports about significant events provide a valid proxy for official records when medical records and administrative data are unavailable . Had mothers been asked to provide copies of their children’s medical records it would no longer have been an anonymous study and would have resulted in few completed questionnaires. We were advised by homeschool leaders that recruitment efforts would have been unsuccessful had we insisted on obtaining the children’s medical records as a requirement for participating in the study.
A further potential limitation is under-ascertainment of disease in unvaccinated children. Could the unvaccinated have artificially reduced rates of illness because they are seen less often by physicians and would therefore have been less likely to be diagnosed with a disease? The vaccinated were indeed more likely to have seen a doctor for a routine checkup in the past 12 months (57.5% vs. 37.1%, p < 0.001; OR 2.3, 95% CI: 1.7, 3.1). Such visits usually involve vaccinations, which nonvaccinating families would be expected to refuse. However, fewer visits to physicians would not necessarily mean that unvaccinated children are less likely to be seen by a physician if their condition warranted it. In fact, since unvaccinated children were more likely to be diagnosed with chickenpox and whooping cough, which would have involved a visit to the pediatrician, differences in health outcomes are unlikely to be due to under-ascertainment.
The third surprise was that the authors were not at all as certain as WDDTY in their conclusions: “the study findings should be interpreted with caution. First, additional research is needed to replicate the findings in studies with larger samples and stronger research designs. Second, subject to replication, potentially detrimental factors associated with the vaccination schedule should be identified and addressed and underlying mechanisms better understood. Such studies are essential in order to optimize the impact of vaccination of children’s health.”
The fourth surprise was to find the sponsors of this research:
Generation Rescue is, according to Wikipedia, a nonprofit organization that advocates the incorrect view that autism and related disorders are primarily caused by environmental factors, particularly vaccines. These claims are biologically implausible and are disproven by scientific evidence. The organization was established in 2005 by Lisa and J.B. Handley. They have gained attention through use of a media campaign, including full page ads in the New York Times and USA Today. Today, Generation Rescue is known as a platform for Jenny McCarthy‘s autism and anti-vaccine advocacy.
The Children’s Medical Safety Research Institute (CMSRI) was, according to Vaxopedia, created by and is funded by the Dwoskin Family Foundation. It provides grants to folks who will do research on “vaccine induced brain and immune dysfunction” and on what they believe are other “gaps in our knowledge about vaccines and vaccine safety”, including:
- vaccine additives, from aluminum adjuvants and mercury preservatives to other “toxins,” like formaldehyde, sodium borate, polysorbate 80, plus foreign proteins from the culture medium such as chicken embryos, monkey kidneys, cells from aborted fetal tissue, and viral DNA, etc.
- what they think is bias in the reporting of vaccine risks and benefits
- novel vaccine-associated autoimmune diseases, like ASIA syndrome and Macrophage Myofasciitis Syndrome
While they claim that they are not an anti-vaccine organization, it should be noted that Claire Dwoskin once said that “Vaccines are a holocaust of poison on our children’s brains and immune systems.”
Did I say SURPRISE?
I take it back!
When it comes to WDDTY, nothing does surprise me.
We have repeatedly discussed on this blog the fact that many alternative practitioners are advising their patients against vaccinations, e. g.:
- Governments take action to prevent vaccination-rates from falling
- Use of alternative medicine is associated with low vaccination rates
- Integrative medicine physicians tend to harbour anti-vaccination views
- Vaccination: chiropractors “espouse views which aren’t evidence based”
- Faith-healing as an alternative to vaccination?
- Recommending homeoprophylaxis is unethical, irresponsible and possibly even criminal
- Chiropractors are undermining public health
- CAM use is risk factor for the failure to immunise children
- Let’s be blunt: homeopathy is bogus – but homeoprophylaxis is worse, much worse!
- Are mothers being taught by homeopaths to become anti-vaxers?
- Some naturopaths are clearly a danger to public health
There is little doubt that this phenomenon contributes to low immunisation rates. This, in turn, is a contributing factor to outbreaks of measles and other infectious diseases. The website of the European Centre for Disease Prevention and Control has recently published data on measles outbreaks in Europe:
Bulgaria: There is an increase by three cases since 21 July 2017. Since the beginning of 2017 and as of 16 July, Bulgaria reported 166 cases. During the same time period in 2016 Bulgaria reported one case.
France: On 27 July 2017 media quoting the French Minister of Health reported the death of a 16-year-old unvaccinated girl. She had fallen sick in Nice and died on 27 June 2017 in Marseille.
Germany: There is an increase by four cases since the last report on 21 July 2017. Since the beginning of 2017 and as of 26 July, Germany reported 801 cases. During the same time period in 2016 Germany reported 187 cases.
Italy: There is an increase by 170 cases since 21 July 2017. Since the beginning of 2017 and as of 25 July, Italy reported 3 842 cases, including three deaths. Among the cases, 271 are healthcare workers. The median age is 27 years, 89% of the cases were not vaccinated and 6% received only one dose of vaccine.
Romania: There is an increase by 229 cases, including one additional death, since 21 July 2017. Since 1 January 2016 and as of 21 July 2017, Romania reported 8 246 cases, including 32 deaths. Cases are either laboratory-confirmed or have an epidemiological link to a laboratory-confirmed case. Infants and young children are the most affected groups. Timis, in the western part of the country closest to the border with Serbia, is the most affected district with 1 215 cases. Vaccination activities are ongoing in order to cover communities with suboptimal vaccination coverage.
Spain: There is an increase by seven cases since 14 July 2017. Since the beginning of 2017 and as of 25 July, Spain reported 145 measles cases.
United Kingdom: Public Health Wales reported two additional cases related to the outbreak in Newport and Torfaen, bringing the total to ten cases related to this outbreak. In England and Wales there is an increase by 76 cases since 21 July 2017. Since the beginning of 2017 and as of 23 July 2017, England and Wales reported 922 cases. In the same time period in 2016, they reported 946 cases.
In addition to the updates listed above ECDC produces a monthly measles and rubella monitoring report with surveillance data provided by the member states through TESSy. The last report was published on 11 July 2017 with data up to 31 May 2017.
Measles outbreaks continue to occur in EU/EEA countries. There is a risk of spread and sustained transmission in areas with susceptible populations. The national vaccination coverage remains less than 95% for the second dose of MMR in the majority of EU/EEA countries. The progress towards elimination of measles in the WHO European Region is assessed by the European Regional Verification Commission for Measles and Rubella Elimination (RVC). Member States of the WHO European Region are making steady progress towards the elimination of measles. At the fifth meeting of the RVC for Measles and Rubella in October 2016, of 53 countries in the WHO European Region, 24 (15 of which are in the EU/EEA) were declared to have reached the elimination goal for measles, and 13 countries (nine in the EU/EEA) were deemed to have interrupted endemic transmission for between 12 and 36 months, meaning they are on their way to achieving the elimination goal. However, six EU/EEA countries were judged to still have endemic transmission: Belgium, France, Germany, Italy, Poland and Romania. More information on strain sequences would allow further insight into the epidemiological investigation.
All EU/EEA countries report measles cases on a monthly basis to ECDC and these data are published every month. Since 10 March 2017, ECDC has been reporting measles outbreaks in Europe on a weekly basis and monitoring worldwide outbreaks on a monthly basis through epidemic intelligence activities. ECDC published a rapid risk assessment on 6 March.

Personally, I believe that it is high time to stop the rhetoric and actions of the anti-vaccination movements. This includes educating alternative practitioners and their patients. If necessary, we need regulation that prohibits their dangerous and unethical activities.
I was surprised to receive this email yesterday: “Hello Edzard Ernst, You may remember I got in touch last week regarding losing a loved one to the ravages of drugs or alcohol. I just wanted to remind you that Narconon is here to help. For over fifty years Narconon drug and alcohol rehabilitation centres have been successfully reversing the tide of addiction for men and woman from all walks of life. The Narconon programme has saved them from the misery of addiction, and the potential of an early grave. We not only address the cause of the addiction, we resolve them…”
The email was signed by a man from ‘Narconon International’. First I thought someone has been counting the empty bottles in my bin, then I read it again and noticed the word ‘NARCONON’ and remembered that I once wrote about it. A quick search located my article from THE GUARDIAN 2012:
Imagine a therapy that “enables an individual to rid himself of the harmful effects of drugs, toxins and other chemicals that lodge in the body and create a biochemical barrier to spiritual well-being“. If you were told that the treatment was entirely natural and had already “enabled hundreds of thousands to free themselves from the harmful effects of drugs and toxins and so achieve spiritual gains”, wouldn’t you be tempted to try it?
Who doesn’t want a body free of nasty chemicals? And who wouldn’t be delighted at the chance to counter a growing threat to an “advancement in mental … wellbeing”?
These claims are being made for the “Purification Rundown” (“Purif” for short) and the closely related Narconon detox programmes, which mainly consist of regular exercise, sauna and nutrition, with industrial doses of vitamins and minerals added for good measure. Some of the claims are quite specific: the Purif programme is supposed to increase your IQ, reduce the level of cancer-causing agents in your body, and even enable you to lose weight easily and quickly. The Narconon programme is more specifically targeted at drug and alcohol dependency and is claimed to have an impressive success rate of 75%.
Both programmes were developed by L Ron Hubbard (1911-1986) and are currently marketed by the Church of Scientology. The CoS is not generally known to be an organisation that promotes healthcare programmes. Hubbard, the pulp-fiction writer who founded the CoS, portrayed himself somewhat over-optimistically as a pioneer, innovator and nuclear physicist.
He taught his followers that, at their core, humans contain a “thetan”. After creating the universe, thetans accidentally became trapped in physical bodies and, through scientology, we can restore the immortal, omnipotent, god-like powers of the “thetan” within us. Weird stuff that is the preserve of Hollywood eccentrics, you might think, but perhaps the CoS’s detox-ventures are an attempt to conquer new territory?
A typical course of treatment lasts several weeks and consists of many hours of exercise and sauna every day. This regimen is supplemented with megadoses of vitamins and minerals, which can cause problems. Niacin, one vitamin that is given in high doses as part of the regimen, can be particularly dangerous. The US National Institutes of Health warns that at high doses it can cause “liver problems, gout, ulcers of the digestive tract, loss of vision, high blood sugar, irregular heartbeat, and other serious problems.” It should not be taken by people who already have liver damage.
Seven fatalities of people undergoing the Narconon programme are currently being investigated in Oklahoma, although the CoS says these deaths are not connected with the treatment regimen itself.
Whatever the truth regarding these deaths, a review of the evidence about the treatment regimen’s effectiveness – carried out by the Norwegian Knowledge Centre for the Health Services in 2008 – found no good evidence that the Narconon programme works:
There is currently no reliable evidence for the effectiveness of Narconon as a primary or secondary drug prevention program. This is partly due to the insufficient research evidence about Narconon and partly due to the non-experimental nature of the few studies that exist.
The claim that such detox treatments eliminate toxins from the body is, of course, easily testable. All we would need to do is define what toxin we are talking about and measure the change in levels of that toxin compared with a control group of volunteers who did not receive the detox.
But such studies are not available. Why? Do the marketing men believe in their own claims? Maybe they feel that profits and evidence are like fire and water? Or possibly the thetans have an aversion to science?
If you think that the Purif, Narconon or any other form of alternative detox eliminates toxins, you might be mistaken. Most clients have lost some money, many have lost their ability to think straight, some may even have lost their lives. But there is no reliable evidence that they have actually lost any toxins.
END OF MY 2012 ARTICLE
In 2012, I found no evidence to suggest that NARCONON works. Now, I looked again and found this article reporting a non-randomised, controlled study:
“In 2004, Narconon International developed a multi-module, universal prevention curriculum for high school ages based on drug abuse etiology, program quality management data, prevention theory and best practices. We review the curriculum and its rationale and test its ability to change drug use behavior, perceptions of risk/benefits, and general knowledge. After informed parental consent, approximately 1000 Oklahoma and Hawai’i high school students completed a modified Center for Substance Abuse Prevention (CSAP) Participant Outcome Measures for Discretionary Programs survey at three testing points: baseline, one month later, and six month follow-up. Schools assigned to experimental conditions scheduled the Narconon curriculum between the baseline and one-month follow-up test; schools in control conditions received drug education after the six-month follow-up. Student responses were analyzed controlling for baseline differences using analysis of covariance. At six month follow-up, youths who received the Narconon drug education curriculum showed reduced drug use compared with controls across all drug categories tested. The strongest effects were seen in all tobacco products and cigarette frequency followed by marijuana. There were also significant reductions measured for alcohol and amphetamines. The program also produced changes in knowledge, attitudes and perception of risk. The eight-module Narconon curriculum has thorough grounding in substance abuse etiology and prevention theory. Incorporating several historically successful prevention strategies this curriculum reduced drug use among youths.”
The question arises: would I send anyone to the NARCONON programme?
My answer is NO!
Not because the trial is lousy (which it is) and not because the programme is too expensive (which it is); I would not send anyone to any institution that has even the slightest links to Scientology.
The ‘Daily Mail’ is not a paper famed for its objective reporting. In politics, this can influence elections; in medicine, it can endanger public health.
A recent article is a case in point, I think.
START OF QUOTE
Traditional Chinese medicines could help prevent heart disease and the progression of pre-diabetes, according to research. Some herbal treatments proved as effective in lowering blood pressure as Western drugs and improved heart health by lowering cholesterol, scientists found. Certain alternative medicines could lower blood sugar and insulin levels, too.
Chinese medicines could be used alongside conventional treatments, say researchers from Shandong University Qilu Hospital in China. Or they can be beneficial as an alternative for patients intolerant of Western drugs, they said in their review of medical studies over a ten-year period. Senior review author from the university’s department of traditional Chinese medicine said: ‘The pharmacological effects and the underlying mechanisms of some active ingredients of traditional Chinese medications have been elucidated. Thus, some medications might be used as a complementary and alternative approach for primary and secondary prevention of cardiovascular disease.”
It’s potentially good news for people living with diabetes, which is now a global epidemic and has proved a tricky condition to manage for many people. High blood pressure is very common too, affecting more than one in four adults in the UK, although many won’t show symptoms and realise it. If untreated, it increases your risk of serious problems including heart disease, the number one killer globally.
The Chinese have used herbs for treating diseases for thousands of years and have become increasingly popular in Europe and North America, mainly as complement to Western medicine. But the researchers also warn that much of the research conducted have limitations and so their long-term effects are not proven.
Herbs for high blood pressure
The blood pressure-lowering effect of herb zhongfujiangya was found to be similar to that of oral anti-hypertension medication benazeprilm, which goes by the brand name Lotensin. Similarly, patients treated for eight weeks with herbal tiankuijiangya had a lower reading than those given a placebo. Herbal Jiangya tablets were found to ‘significantly lower’ systolic blood pressure, that is the amount of pressure in your arteries during contraction of your heart muscle compared to a fake treatment. The herb Jiangyabao also had a significant effect compared to a placebo, but just at night. But overall, compared to the drug Nimodipine, a calcium channel blocker, it worked just as well. Qiqilian capsules also proved more effective compared to a placebo.
Herbs for diabetes
The team report some Chinese medicines medications – such as xiaoke, tangminling, jinlida, and jianyutangkang – have a ‘potent’ effect on lowering blood sugar levels and b-cell function, which controls the release of insulin. Some remedies – such as tangzhiping and tianqi – might prevent the progression of pre-diabetes to diabetes, they note.
Herbs for cholesterol
The researchers looked at research on dyslipidemia, the term for unbalanced or unhealthy cholesterol levels. They found that jiangzhitongluo, salviamiltiorrhiza and pueraria lobata, and zhibitai capsule all have a ‘potent lipid-lowing effect’.
Herbs for heart disease
Some traditional Chinese medicines such as qiliqiangxin, nuanxin, shencaotongmai, and yangxinkang, might be effective in improving function in patients with chronic heart failure, they wrote.
Limitations with trials
But Western scientists often reject Chinese medicine for specific reasons, warned Dr Zhao’s team. Chinese medicines are frowned upon because they do not go through the same exhaustive approval process as trials conducted domestically, they pointed out. Plus, one treatment can be made of many different ingredients with various chemical compounds, making it hard to pinpoint how their benefits work. ‘One should bear in mind that traditional Chinese medicine medications are usually prescribed as complex formulae, which are often further manipulated by the practitioner on a personalized basis,’ said Dr Zhao.

Apart from the fact that this article is badly written, it is also misleading to the point of being outright dangerous. Regular readers of my blog will be aware that Chinese research is everything but reliable; there are practically no Chinese TCM-trials that report negative results. Furthermore, the safety of Chinese herbal preparations is as good as unknown and they are often contaminated with toxic substances as well as adulterated with synthetic drugs. Most of these preparations are also unavailable outside China. Moreover, Chinese herbal treatments are usually individualised (mixtures are tailor-made for each individual patient), and there is no good evidence that this approach is effective. Crucially, the trial evidence is often of such poor quality that it would be a dangerous mistake to trust these findings.
None of these important caveats, it seems, are important enough to get a mention in the Daily Mail.
Don’t let the truth get in the way of a sensational story!
Let’s just for a moment imagine what would happen if people took the Mail article seriously (is there anyone out there who does take the Mail seriously?). In a best case scenario, they would take Chinese herbs in addition to their prescribed medication. This might case plenty of unwanted side-effects and herb-drug interactions. In addition, people would lose a lot of their hard-earned cash. In a worst case scenario, they would abandon their prescribed medication for dubious Chinese herbal mixtures. This could cause thousands of premature deaths.
With just a little research, I managed to find the original article on which the Mail’s report was based. Here is its abstract:
Traditional Chinese medicine (TCM) has more than 2,000 years of history and has gained widespread clinical applications. However, the explicit role of TCM in preventing and treating cardiovascular disease remains unclear due to a lack of sound scientific evidence. Currently available randomized controlled trials on TCM are flawed, with small sample sizes and diverse outcomes, making it difficult to draw definite conclusions about the actual benefits and harms of TCM. Here, we systematically assessed the efficacy and safety of TCM for cardiovascular disease, as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and potential mechanisms. Results indicate that TCM might be used as a complementary and alternative approach to the primary and secondary prevention of cardiovascular disease. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.
In my view, the authors of this review are grossly over-optimistic in their conclusions (but nowhere near as bad as the Mail journalist). If the trials are of poor quality, as the review-authors admit, no firm conclusions should be permissible about the usefulness of the therapies in question.
As the Mail article is obviously based on a press release (several other papers worldwide reported about the review as well), it seems interesting to note what the editor of the Journal of the American College of Cardiology (the journal that published the review) recently had to say about the responsibility of journalists and researchers:
START OF QUOTE
…I would like to suggest that journalists and researchers must share equally in shouldering the burden of responsibility to improve appropriate communication about basic and clinical research.
First, there is an obligation on the part of the researchers not to inflate the importance of their findings. This has been widely recognized as damaging, especially if bias is introduced in the paper…
Second, researchers should take some responsibility for the creation of the press release about their research, which is written by the media or press relations department at their hospital or society. Press releases are often how members of the media get introduced to a particular study, and these releases can often introduce errors or exaggerations. In fact, British researchers evaluated 462 press releases on biomedical and health-related science issued by 20 leading U.K. universities in 2011, alongside their associated peer-reviewed research papers and the news stories that followed (n = 668). They found that 40% of the press releases contained exaggerated advice, 33% contained exaggerated causal claims, and 36% contained exaggerated inference to humans from animal research. When press releases contained such exaggeration, 58%, 81%, and 86% of news stories, respectively, contained further exaggeration, compared with rates of 17%, 18%, and 10% in the news when the press releases were not exaggerated. Researchers should not be excused from being part of the press release process, as the author(s) should at least review the release before it gets disseminated to the media. I would even encourage researchers to engage in the process at the writing stage and to not allow their hospital’s or society’s public relations department to extrapolate their study’s results. Ultimately, the authors and the journals in which the studies are published will be held accountable for the information that trickles into the headlines, not the public relations departments, so we must make sure that the information is accurate and representative of the study’s actual findings.

Sound advice indeed.
Now we only need to ALL follow it!!!
Currently, over 50 000 000 websites promote alternative medicine, and consumers are bombarded with information not just via the Internet, but also via newspapers, magazines and other sources. This has the potential of needlessly separating them from their cash or even seriously harming their health. As there is little that protects us from greedy entrepreneurs and over-enthusiastic therapists, we should think about protecting ourselves. Here I will provide five simple tips that may fortify you against fake news in the realm of alternative medicine.
Imagine you read somewhere that the condition you are affected by is curable (or at least improvable) by THERAPY XY. It is only natural that you are exited by this news. Before you now rush to the next health shop or alternative medicine centre, it is worth asking yourself the following questions:
- Is the claim plausible? As a rule of thumb, it is fair to say that, if it sounds too good to be true, it probably is too good to be true. Not so long ago, UK newspapers reported that a herbal mixture called ‘CARCTOL’ had been discovered to be an efficacious and safe cancer cure (before that, it was Essiac, shark cartilage, Laetrile and many more). I only needed a minimal amount of research to find that the claim had no basis in fact. Come to think of it, it is not plausible that any alternative therapy will ever emerge as a miracle cure for any condition, particularly a serious disease like cancer. It is also not plausible that a herbal mixture would ever prove to be a cure for a wide range of different cancers. The very idea of such ‘cures’ is a contradiction in terms. If an alternative therapy ever did turn out to be efficacious, it would become mainstream even before the clinical tests to prove its efficacy are fully concluded. The notion of an alternative cure presumes that conventional scientists and clinicians reject a treatment simply because it originated from the realm of alternative medicine. There is no precedent that this has ever occurred, and I am sure it will never happen in future.
- What is the evidence for the claim? In the case of CARCTOL, the claim was based on a UK doctor apparently observing that, in several patients, tumours had been melting like butter in the sun after they took this herbal mixture. One particularly irresponsible headline read: “I’ve seen herbal remedy make tumours disappear, says respected cancer doctor.” This, however, is no evidence but mere anecdotes, and we confuse the two at our peril. Remember: the plural of anecdote is anecdotes, not evidence. With anecdotes, we can never be sure about cause and effect. Therapeutic claims must be based on good evidence, e.g. controlled clinical trials.
- Who is behind the claim? In the UK, the CARCTOL claim emerged around 2004 and originated mainly from Dr Rosy Daniel. In the above newspaper article, she was called ‘a respected cancer doctor’. Personally, I do NOT ‘respect’ someone who makes claims of this nature without having good evidence. And a ‘cancer doctor’ is usually understood to be an oncologist; to the best of my knowledge, Dr Daniel is NOT an oncologist. In fact, she now calls herself a ‘Lifestyle and Integrative Medicine Consultant’. Faced with an important new health claim, one should always check who is behind it. Check out whether this person is reputable and free of conflicts of interest. An affiliation to a reputable university is usually more convincing than being a director of your own private heath centre.
- Where was the claim published? The CARCTOL story had been published in newspapers – and nowhere else! Even today, there is only one Medline-listed publication on the subject. It is my own review of the evidence which, in 2004, concluded that “The claim that Carctol is of any benefit to cancer patients is not supported by scientific evidence.” *** If important new therapeutic claims like ‘therapy xy cures cancer’ are reported in the popular media, you should always check where they were first published (or simply dismiss it without researching it). It is unthinkable that such an important claim is not made first in a proper, peer-reviewed article in a good medical journal. Go on ‘Medline’, conduct a quick search and find out whether the new findings have been published. If the claim does not come from peer-reviewed journals, forget about it. If it has been published in any journal that has alternative, complementary, integrative or similar terms in its name, take it with a good pinch of salt.
- Is there money involved? In the case of CARCTOL, the costs were high. I was called once by a woman who had read my article telling me that she was pursued by the doctor who had treated her husband. Tragically, the man had nevertheless died of his cancer, and the widow was now pursued for £8 000 which she understandably was reluctant to pay. Many new treatments are expensive. So, high costs are not necessarily suspicious. Still, I advise you to be extra cautious in situations where there is the potential for someone to make a fast buck. Financial exploitation is sadly rife in the realm of alternative medicine.
A similar checklist originates from a team of experts. Researchers from Uganda, Kenya, Rwanda, Norway, and England, worked to identify the most important ideas a person would need to grasp thinking critically about health claims. They came up with excellent points:
- Just because a treatment is popular or old does not mean it’s beneficial or safe.
- New, brand-name, or more expensive treatments may not be better than older ones.
- Treatments usually come with both harms and benefits.
- Beware of conflicts of interest — they can lead to misleading claims about treatments.
- Personal experiences, expert opinions, and anecdotes aren’t a reliable basis for assessing the effects of most treatments.
- Instead, health claims should be based on high-quality, randomized controlled trials.
Alternative medicine can easily turn into a jungle or even a nightmare. Before you fall for any dubious claim that THERAPY XY is good for you, please go through the simple sets of questions above. This might protect you from getting ripped off or – more importantly – from getting harmed.
*** After this article had been published, I received letters from layers threatening me with legal action unless I withdrew the paper. I decided to ignore them, and no legal action followed.
