An ‘epidemic’ of childhood tooth decay in the fluoridated Republic of Ireland

28 Feb

Background information: Ireland, the only country in the European Union with a nationwide mandate for water fluoridation -via the Health (Fluoridation of Water Supplies) Act 1960, which mandated compulsory fluoridation by local authorities. 3,250,000 Irish people receive artificially-fluoridated water.

Geren Island Water Treatment FacilityThe agent used is hydrofluorosilicic acid. Corrosive to most metals it eats through concrete and Hazmat suits (impermeable whole-body garments must be worn to handle it as a gas may be released which damages the lungs. This and other adverse health effects are listed by NIOSH (US government agency).

private member’s bill to end fluoridation was defeated in the Dáil on 12 November 2013. It was supported by Sinn Féin and some of the technical group and opposed by the Fine Gael-Labour government and Fianna Fáil.

Early in 2014, Cork County Council and Laois County Council passed motions for the cessation of water fluoridation. In Autumn 2014, Cork City Council, Dublin City Council and Kerry County Council passed similar motions.

irsih-jda-coverToday, Aaron Rogan in The Times reports that a study by University College Cork published in this month’s Journal of the Irish Dental Association found that 60% of the 347 Irish children who required dental treatment under general anaesthetic before they turned five needed teeth extracted.

Michaela Dalton, president of the HSE dental surgeons group describes it as an ‘epidemic of tooth decay’. “Juices and yoghurts are rotting babies’ teeth but are being sold as replacements for fruit. Sugary cereal bars are sold as healthy snacks. They’re labelled as no-added sugar and all-natural but they have concentrated fruit sugars, which are really acidic and rotting teeth” Dr Dalton said.

Another significant finding was that despite a long-established link between economic disadvantage and dental problems, there was no significant class difference for preschool children requiring treatment under general anaesthetic.

“Disadvantaged children have a higher risk of requiring a dental general anaesthesia in their lifetime; however, this is not occurring in isolation, with their equivalents in the higher social group also placing a strain on the system,” the study said.

The programme for government explicitly mentioned that preschool oral health intervention would save the taxpayer money – but the expensive water fluoridation programme already compulsory in Ireland is universally ‘sold’ as an oral health intervention.

Links between exposure to organophosphate pesticides and the onset of diabetes

26 Jan

As the government’s Food Agency is diligently warning the public of possible harm from burnt toast, will it heed a new concern raised by Indian scientists?  

British governments have a poor record when there is a conflict of interest between public health and large arms related/chemical/pharmaceutical companies.

Successive governments resisted acknowledging the harm done by early nuclear tests, Gulf War medication, thalidomide, mercury in infant vaccines and infected imported blood products – even, in the 70s and 80s compelling farmers to use organophosphate-based sheep dip and to this day encouraging the addition of a toxic chemical to drinking water.

The number of diabetes cases in Britain is causing concern; the Medical Research Council (above, a publicly funded government agency) reported in 2015 that there are 3.9 million people living with diabetes in the UK and quotes estimates that more than one in 16 people in the UK has diabetes (diagnosed or undiagnosed).

Richard Bruce sends a link to a report from India by Pallava Bagla published on Tuesday. It records that scientists at Madurai Kamaraj University in Tamil Nadu have found links between the use of pesticides and the high prevalence of diabetes in India (65 million people, second only to China).

They found the prevalence of diabetes in people regularly exposed to insecticides was three-fold higher (18.3 per cent) than in unexposed people (6.2 per cent).

Their results were published in the peer-reviewed journal Genome Biology. They also conducted experiments on mice, in which they found that exposure to pesticides upsets the micro-flora of the gut, leading to the onset of diabetes. Read quite a detailed account here: http://genomebiology.biomedcentral.com/articles/10.1186/s13059-016-1134-6

The team – which had been conducting the research in rural areas of South India – suggests that if people are continuously exposed to common OP pesticides like Malathion and Chlorpyrifos, they can get diabetes even when they do not have the other risk factors – obesity and high cholesterol.

This was a departure from traditional findings: the 3,080 people surveyed were physically active and did not have the better known risk factors for diabetes like obesity and high cholesterol.

OP pesticides are widely used in agriculture. Malathion is used even in urban areas to control mosquitoes and termites. They are known to affect memory and concentration, cause depression, headache and speech difficulties. The US Environmental Protection Agency (at risk under the new president?) publishes findings that these are amongst several classes of toxic chemicals that can harm children; researchers say OPs could be a contributing factor in learning disability and behavioural problems in children.

The scientists at Madurai Kamaraj University suggested that, in view of the high occurrence of diabetes in India, the use of OP (organophosphate) pesticides should be reconsidered.

 

 

 

Science, precaution, innovation: learn tragically ‘late lessons from early warnings’

30 Jul

 

Glyphosate herbicides, harmful pharmaceuticals, infected blood transfusions, mercury preservative in infant vaccines, organophosphate insecticides, GM technology and fluoridation of the water supply . . . the damage to human and environmental health has been incalculable.

pprof mcgladeAs Professor Jacqueline McGlade, Chief Scientist and Director of the Division of Early Warning and Assessment of the United Nations Environment Programme, said in her preface to Late lessons from early warnings: science, precaution, innovation:

“There is something profoundly wrong with the way we are living today. There are corrosive pathologies of inequality all around us — be they access to a safe environment, healthcare, education or clean water. These are reinforced by short-term political actions and a socially divisive language based on the adulation of wealth . . .

“One thing that has become clearer over the past decade is that certain chemical substances are highly stable in nature and can have long-lasting and wide ranging effects before being broken down into a harmless form. The risk of a stable compound is that it can be bio-accumulated in fatty tissues at concentrations many times higher than in the surrounding environment . . . So exposure to toxic chemicals and certain foodstuffs are at risk of causing harm, especially to vulnerable groups such as foetuses in the womb or during childhood when the endocrine system is being actively built. Even with small dose exposures, the consequences can in some instances be devastating with problems ranging from cancer, serious impacts on human development, chronic diseases and learning disabilities”.

chemical exposures coverProfessor McGlade points out that well-informed individuals and communities would ‘more properly’ set ‘the power to act’, than current political systems which have become ‘silted up by vested interests and a determination to protect assets’ – and, we would add, to accumulate profits. She calls for “a more ethical form of public decision-making based on a language in which our moral instincts and concerns can be better expressed . . .”

Above, a book by Claudia Miller, M.D., M.S., a tenured Professor in Environmental and Occupational Medicine and Vice Chair of the Department of Family and Community Medicine of the University of Texas Health Science Center at San Antonio (UTHSCSA), who has written extensively on the health effects of low-level chemical exposures.

One simple measure could be adopted. Every scientific report or review should be prefaced by a declaration of the researcher’s competing financial interests

From the Nature/ British Dental Journal’s declaration of the authors’ competing financial interests Critique of the review of ‘Water fluoridation for the prevention of dental caries’ published by the Cochrane Collaboration in 2015, we learn that – out of 17 – these authors had such an interest – see footnote, with names added to the initials in the list.

The Cochrane review noted- amongst many other findings – that only two studies since 1975 have looked at the effectiveness of reducing cavities in baby teeth, and found fluoridation to have no statistically significant impact – and within the ‘before and after’ studies none showed the benefits of fluoridated water for adults.

In view of the authors’ competing interests it is not surprising that they cast doubt on the validity of the unfavourable findings of the Cochrane Review, which is ’unconstrained by commercial and financial interests’.

Reviews into antibiotics and anti-microbial resistance proliferate

21 Dec

tracy and pigTracy Worcester has drawn our attention to the subject of antibiotic resistance, which is growing – developing not in humans, but in bacteria that can then infect humans. Surgical and cancer chemotherapy patients rely on antibiotics to protect them from potentially life-threatening illnesses and declining efficacy could turn routine procedures into life-threatening ones.

Calls for funding aka ‘adequate market incentives’

antibiotics report coverAmerica’s Center for Disease Dynamics, Economics & Policy (CDDEP) produces independent, multidisciplinary research to advance the health and wellbeing of human populations in the United States and around the world.

Its October publication (right) estimates that between 38·7% and 50·9% of pathogens causing surgical site infections and 26·8% of pathogens causing infections after chemotherapy are resistant to standard prophylactic antibiotics in the USA.

RAND Europe and KPMG have both assessed the future impact of antimicrobial resistance [AMR] and a recent Chatham House report on new business models for antibiotics highlighted the problem of inadequate market incentives.

The use of antibiotics in agriculture

Haroon Siddique writes in the Guardian about another study, commissioned by David Cameron. The Review on Antimicrobial Resistance has been produced by a team of economists and administrators with one scientific adviser, supported by the Wellcome Trust fund.

It finds that the unpredictable nature of the development of resistance to such drugs, and the limits put on the sale of antibiotics to ensure they are used appropriately, are two factors which many pharmaceutical companies mention to explain why they have cut back or stopped altogether their investment in R&D on new antimicrobials.

It warns that the use of antibiotics in agriculture is fuelling drug resistance and must be cut back or even banned where they are important for humans – see CDDEP risk assessment below, deemed over-cautious by some.

antibiotics 2graph by 2050

The review found that global use of antimicrobials in food production at least matched that by humans, extending even to the widespread application in some areas of “last resort” antibiotics for humans – which cannot be replaced when ineffective – to animals.

Acknowledging that the proper use of antibiotics is essential for treating infections in animals, as in humans, and offers considerable benefits for food production, the authors stress that “excessive and inappropriate” deployment, including to stop development of infections within a flock or herd, or simply to increase the pace at which animals gain weight, is a problem.

The team proposes that there should be a limit for each country to reduce antibiotic use in food production to an agreed level per kilogram of livestock and fish.

This should be determined by experts, but they suggest that a good starting point would be reducing levels to that of Denmark – an average of less than 50mg of antibiotics per year per kilogram of livestock in the country. Denmark has combined low use with being one of the world’s largest exporters of pork.

Tracy Worcester has a different proposal: use the power of the purse

Instead of buying meat from animal factories that cram so many pigs into vast sheds which need routine doses of antibiotics to keep the animals alive, we can buy meat from real farms. Pigs on outdoor farms, or indoors with adequate space and bedding, are healthy and hardly ever need antibiotics.

One of her fellow-campaigners, actor Dominic West, opposed a recent factory farming application. He hopes that when we buy British we know we are not supporting this type of cruel and dangerous farming: ‘The costs are much too high, from the superficial horrors of stench and stressed, unhealthy animals to antibiotic resistance that brings us closer to the end of antibiotics as a cure for human diseases. He says, ‘The world must move on, and we can all help by only buying pork from high welfare UK farms.’

Tracy points out that we have the choice to buy meat with the high welfare labels RSPCA Assured, Outdoor Bred, Free Range or Organic – eat less meat as Anna advocates – or go meat-free. See the World Health Organisation on the health issues here.

Frances Kelsey: a true, independent-minded scientist

20 Aug

frances kelseyAs reports about alleged corruption in science surface, following news over the years of the disturbing side effects of potent pharmaceuticals, it is really heartwarming to read the story of Frances Kelsey, US FDA drug regulator, who recently died.

Merrell, an Ohio company, licensed thalidomide from Grünenthal of Germany and it had been available in Europe for years; Merrell expected its application for US approval would be swiftly rubber-stamped, as did Kelsey’s bosses.

After asking ‘questions that regulators elsewhere failed to’ as the FT put it, she became concerned about the lack of evidence to prove the safety of using thalidomide when prescribed to pregnant women for morning sickness.

She was still demanding answers when reports started to emerge from Europe of a link to infants born with missing or deformed limbs. The earliest case involved a girl born with no ears on Christmas Day 1956 — the daughter of a Grünenthal employee. Eventually thalidomide caused birth defects in more than 10,000 people around the world.

Wiki: “Mercédes Benegbi, a thalidomide victim and the head of the Thalidomide Victims Association of Canada, praised Dr. Kelsey for showing strength and courage by refusing to bend to pressure from drug company officials, and said “To us, she was always our heroine, even if what she did was in another country.”

The FT reports that Jerry Avorn, professor at Harvard Medical School, says thalidomide showed the need for regulators to maintain a sceptical approach in the face of industry pressure. “She was vilified as a pointy-headed bureaucrat; someone pushing a pencil and stifling innovation.”

He fears that renewed pharma lobbying to relax regulation is threatening Kelsey’s legacy.

Self-regulated companies: polluting the environment in USA, Canada, India and China

27 Jul

joakim 2 bergmannJoakim Bergman is Chief Executive of Changing Markets, a social enterprise which supports environmentally sustainable companies and products to take market share from less sustainable competitors and helps NGOs to run better campaigns that ‘more efficiently activate market shifts’.

He recently wrote to the Financial Times about the dumping of untreated antibiotic waste affecting the health of local communities and also contributes to the global rise of antibiotic-resistant bacteria. Mr Bergman highlighted a major UK government-backed review into antimicrobial resistance (more here) which estimates that by 2050, drug-resistant infections could kill 10m people per year globally and reported that the UK’s chief medical officer has spoken of this as a “catastrophic threat”.

Some “disturbing” environmental damage in India and China by ‘trusted brands’

He refers to an article in the FT which reports institutional investors’ concerns over the “disturbing” environmental damage resulting from multinational drug companies manufacturing in India. Recent research conducted by Changing Markets confirms many other reports showing that pharmaceutical pollution is a huge problem in China, where between 80 and 90% of the world’s antibiotic raw materials are manufactured. In both countries, multinational pharmaceutical plants are failing to treat and manage toxic and drug-rich waste, while their clients – including trusted brands – are ‘turning a blind eye to the problem’.

water pollution america

To a lesser extent, European countries, Canada and America (above) also have chemically polluted water. Read more here. According to a new Cary Institute study, Emma Rosi-Marshall, the lead author of a new study, has tracked pharmaceutical pollution in waters across the globe leading to disruption of ecosystem of streams, including American rivers in New York, Maryland and Indiana. She said when waste water is moved to sewage treatment facilities it is not treated for the removal of pharmaceuticals. Consequently, streams and rivers are exposed to synthetic compounds including antibiotics, stimulants, antihistamines and analgesics.

Concern about the problem in Eastern Europe is evident in the EU Guidelines on waste disposal and in 1999 the UNO World Health Organisation issued detailed guidelines in a more readable document, including disposal methods. In section 1.8 it stresses many dangers from ‘improper disposal or non-disposal of expired pharmaceuticals, including contamination of water supplies or local sources used by nearby communities or wildlife’.

Many companies, including Pfizer and AstraZeneca, have signed up to the Pharmaceutical Supply Chain Initiative, which has clear guidelines on wastewater management, but in light of the recent revelations it seems that the majority are failing to observe these guidelines.

Bergman concludes: “Without rapid action to remedy this, the global pharmaceutical industry risks becoming complicit in a public health disaster of monumental proportions”.

A pharmaceuticals market of 800,000 – and growing

“Drug companies got out of antibiotics as their attention switched to much more lucrative daily medicines for chronic diseases”

jeremy huntIn March, at the World Health Organisation’s first Ministerial Conference on Global Action Against Dementia in Geneva, Jeremy Hunt, the UK’s health secretary, announced plans to boost early-stage research into Alzheimer’s disease and other forms of dementia in order to find an effective treatment. Just three new drugs for the condition have reached market in the past 15 years and these only alleviate symptoms.

The WHO conference was supported by the Department of Health of the United Kingdom of Great Britain and Northern Ireland, and the Organization for Economic Cooperation and Development (OECD). Both days were webcast.

Ongoing lifelong drug treatment is very profitable – not so pre-emption

The $100m venture capital fund will be backed by the UK government and several of the world’s biggest pharmaceuticals companies, amongst them US investment bank JPMorgan, GlaxoSmithKline, Johnson & Johnson, Pfizer, Eli Lilly and Biogen.

Drug companies had lost billions of dollars in many failed trials and Patrick Vallance, president of research and development at GlaxoSmithKline, said the venture fund was a good way to spread risk and share expertise.

He added that there are rewarding economic incentives for research. “Nobody doubts that if you find an effective medicine for dementia it will be very profitable.”

True – and discovering and addressing the causes would remove this market opportunity.

Today’s broadcast theme:

Infectious bacteria are becoming resistant to the drugs that used to kill them. The last new class of antibiotics was discovered in the 1980s. There is little in the development pipelines of the world’s pharmaceutical industry. Drug companies got out of antibiotics as their attention switched to much more lucrative daily medicines for chronic diseases. Public funding on antibiotic research has also withered.
