Autism epidemic not caused by shifts in diagnoses; environmental factors likely

Byoliveridley

California’s sevenfold increase in autism cannot be explained by changes in doctors’ diagnoses and most likely is due to environmental exposures, University of California scientists reported. The scientists who authored the new study advocate a nationwide shift in autism research to focus on an array of potential factors in the environment that babies and fetuses are exposed to, including pesticides, viruses and chemicals in household products.

Autism epidemic not caused by shifts in diagnoses; environmental factors likely — Environmental Health News

One of the most common arguments you will see about a lot of mental health diagnoses is that doctors have changed their diagnostic practices significantly. While there is evidence of this occurring in diagnoses of childhood depression, anxiety, or even bipolar disorder due to the millions of dollars involved in medication and the attendant corruption, autism is different.

This population study used 17 year data in California and concluded that diagnostic changes were only responsible for a 2 fold increase, not the seven fold increase seen. The rest is unexplained, and the authors attribute it to a confluence of environmental and genetic factors.

And no, for the last time, VACCINES DO NOT CAUSE AUTISM!

  • China Food Quality Questioned

    I mentioned briefly that I would not trust anything coming out of China at this point in time, the Post runs with it this morning.

    China Food Fears Go From Pets To People – washingtonpost.com

    The scandal, which unfolded three years ago after hundreds of babies fell ill in an eastern Chinese province, became the defining symbol of a broad problem in China’s economy. Quality control and product-safety regulation are so poor in this country that people cannot trust the goods on store shelves.

    China has been especially poor at meeting international standards. The United States subjects only a small fraction of its food imports to close inspection, but each month rejects about 200 shipments from China, mostly because of concerns about pesticides and antibiotics and about misleading labeling. In February, border inspectors for the U.S. Food and Drug Administration blocked peas tainted by pesticides, dried white plums containing banned additives, pepper contaminated with salmonella and frozen crawfish that were filthy.

    China’s development in many areas has been remarkably rapid, but one has to remember that basic infrastructure such as food safety standards, environmental controls, etc. follow along a little later. China being what it is, the U.S government really needs to be more careful and comprehensive with its food testing and safety programs. There’s no sense in blaming China for this, the Chinese government can’t possibly control all this activity. It takes both buyer beware, and seller beware to ensure safety. The U.S should take the European Union’s approach on this issue.

    India at 60 – A Public Health Perspective

    Byoliveridley

    Well, at least I don’t have to take part in endless parades and listen to speeches any more. But India turned 60 today, and the head of the Indian public health foundation takes stock, and it is sobering.

    The Hindu : Persisting public health challenges

    Recent health indicators in India are a cause for both celebration and concern. While life expectancy at birth has risen to 63 years, infant mortality rate (IMR) and maternal mortality rate (MMR) are still at unacceptably high levels (57 per 1000 and 301 per 100,000 live births respectively). There is widespread disparity among States with Kerala being the star performer. Within States, the rural areas are way behind the urban segments. Even as our economy has grown rapidly, the nutritional status of children has remained stunted, suggesting that wide income disparities are preventing the poor from becoming the beneficiaries of growth.

    Yes, I be the killjoy.

    More from Amartya Sen

    There is reason enough to celebrate many things happening in India right now. But there are failures as well, which need urgent attention. For example, there is still widespread undernourishment in general and child undernutrition in particular–at a shocking level. The failures include, quite notably, the astonishing neglect of elementary education in India, with a quarter of the population–and indeed half the women–still illiterate.

    The average life expectancy in India is still low (below 64) and infant mortality very high (58 per 1,000 live births). It is certainly true that India has narrowed the shortfall behind China in these areas–that is, in life expectancy and infant mortality–but there is still some distance to go for the country as a whole. The problems are gigantic in some of the more “backward” states like Bihar and Uttar Pradesh. And yet there are other states in which the Indian numbers are similar to China’s.

    he goes on…

    If India has to overcome these failures, it has to spend much more money on expanding the social infrastructure, particularly school education and basic health care. It also needs to spend much more in building up a larger physical infrastructure, including more roads, more power supplies and more water. In some of these, the private sector can help. But a lot more has to be spent on public services themselves, in addition to improving the system of delivery of these services, with more attention paid to incentives and disciplines, and better cooperation with the unions, consumer groups and other involved parties.

    Ah, basic and boring infrastructure building!

    Gaping Reminders of Aging and Crumbling Pipes – New York Times

    Gaping Reminders of Aging and Crumbling Pipes – New York Times

    Local and state officials across the country say thousands of miles of century-old underground water and sewer lines are springing leaks, eroding and — in extreme cases — causing the ground above them to collapse. Though there is no master tally of sinkholes, there is consensus among civil engineers and water experts that things are getting worse.

    The Environmental Protection Agency has projected that unless cities invest more to repair and replace their water and sewer systems, nearly half of the water system pipes in the United States will be in poor, very poor or “life elapsed” status by 2020.

    Yes, sewers are unsexy, there’s no new fancy science involved. But water and sewer systems are the very basis of public health, and the biggest reason why Americans don’t die of sleeping sickness and dengue fever (or their subtropical equivalents) in large numbers evey year. People who want to cut taxes and limit government need to keep this in mind. There’s no money to be made out of building and maintaining sewers, it’s a dirty job and government has to do it, or else nobody will, and money is required. We produce the waste, we need to be taxed appropriately for it. It’s that simple.

    The real terrorist: Pollution

    Byoliveridley

    It is true. A staggering number of people die every year due to lack of access to clean water, air or food. Aggregate statistics like these are a good way to summarize the humongous nature of the problem. While reams and reams of coverage and attention are focused on “terrorists”, people all around the world die of much more mundane causes such as bacteria in water, smog, poverty, starvation, malnourishment, etc.

    ScienceDaily: Pollution Causes 40 Percent Of Deaths Worldwide, Study Finds

    About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. Both factors contribute to the malnourishment and disease susceptibility of 3.7 billion people, he says.

    Flame Retardants and Hyperthyroidism in Cats

    Byoliveridley

    Caveat Emptor: They found a correlation, not a causative mechanism. But Polybrominated Diphenyl Ethers (PBDEs, yum!) have structures that can mimic endocrine hormones. Because hormones signal at very low doses and continuously, our whole toxicological risk testing structure of looking for acute effects at high doses and trying to extrapolate those effects to low doses is flawed for endocrine disrupting compounds. We are finally beginning to see some new research, especially with other toxics such as Bisphenol A, which test for chronic conditions and subtle gene and hormonal signalling effects at low doses. After all, small changes in hormone regulation especially at childbirth and a young age can have very serious effects later on in life.

    Inside Bay Area – NEW: Flame retardants linked to thyroid disease in cats

    A mysterious epidemic of thyroid disease in cats may be linked to flame retardants common in carpets, foam furniture and mattresses, according to U.S. Environmental Protection Agency researchers, who suggest that scientists have underestimated the damaging health risk the chemicals pose to humans.

    The research, published Wednesday in the journal Environmental Science and Technology, does not prove these compounds, known as PBDEs, caused the rash of hyperthyroidism in the nation’s household cats over the past 30 years.

    Rather, it lays out a hypothesis, showing that cats are heavily contaminated by these compounds, which leach from household products and are found everywhere, particularly household dust. Cats, meticulous cleaners, ingest PBDE-contaminated dust daily.

    The case of fire retardants is especially difficult because they save many lives, so manufacturers can always point to that fact and resist change. The logical fallacy, however is as follows:

    1. Fire retardants save lives (therefore good)
    2. PBDEs are fire retardants
    3. Therefore, PBDEs are good!!

    The search for a safer fire retardant needs to continue, and will not happen unless the old ones are under pressure of being phased out.

    CMA condemns Asbestos

    Byoliveridley

    The Canadian Medical Association Journal is denouncing the federal government for what it expects will be Canada's continued efforts to block international controls on asbestos at UN-sponsored negotiations next week.

    A strongly worded editorial, appearing in tomorrow's issue of the journal, says the government "knows what it is doing is shameful and wrong" and compared Ottawa's moral stature in continuing to promote the use of the cancer-causing material to that of arms traders.

    The negotiations, known as the Rotterdam Convention, are to start Oct. 27 in Rome. The focus of the talks will be on whether to add the chrysotile variety of asbestos to the world's list of most dangerous substances. Once a substance is listed, countries must give prior informed consent that they know they are buying a highly dangerous material before being allowed to accept any imports.

    via globeandmail.com: Medical journal blasts Ottawa for promoting asbestos abroad

    Canada’s national shame, its export of a killer product not used by Canadians to developing countries where the safeguards it insists on for the ‘safe” use of this product can’t possibly be carried out or enforced. For god’s sake, it’s 700 jobs, and people who can be retrained to do something that does not kill people.
