UNICEF and friends VS the outspoken Anti-vaxxers - BioBlog

Alison Campbell Mar 07, 2018

Back in mid-February, UNICEF NZ posted a piece on the importance of vaccines. Shortly thereafter, the comments thread had been overrun by anti-vaccination pro-disease activists. (I have to say, I’m really impressed with the person who does UNICEF’s social media. Talk about grace and dignity under fire!) This seems to happen every time a story about vaccine-preventable disease hits the … Read More

Paul Connett’s misrepresentation of maternal F exposure study debunked - Open Parachute

Ken Perrott Mar 06, 2018

Anti-fluoride campaigners are misrepresenting a recent Mexican study claiming its findings should cause governments around the world to abandon community water fluoridation (CWF). Their claims are unwarranted because the study has a high degree of uncertainty. Activists are misrepresenting the accuracy of the studies findings. Because Mexico has areas of endemic fluorosis the study itself is not relevant to CWF. Read More

Opinion: Anti-fluoride activist commits “Death by PowerPoint” - Open Parachute

Ken Perrott Feb 28, 2018

We have all sat through boring, and counterproductive, PowerPoint presentations. Boring because the presenter breaks all the rule relevant to the preparation of visual displays.

Ken Perrott Feb 22, 2018

 Data from Bashash et al., (2017). Despite a statistically significant relationship of child IQ with mothers prenatal urinary fluoride, this explains only about 3% of the huge scatter in the data. I haven’t followed the latest speaking tour of Paul Connett – organised by the local Fluoride Free NZ organisation. But I watched a TV interview with him this … Read More

Ken Perrott Feb 15, 2018

Anti-fluoride activists closely follow the publication of results from fluoride studies and react to new scientific papers in one of the following ways: Use it to claim community water fluoridation (CWF) is harmful – even if this requires misrepresentation or distortion of the studies findings (a recent example is the prenatal fluoride/child IQ study of Bashash et al., (2017)  heavily … Read More

More Wellcome reading - Code for life

Grant Jacobs Feb 09, 2018

I know many of my readers are, well, readers. (Ha!) I like book prize longlists, as they give you a selection to browse, all of which will be great efforts. (I’d also encourage browsing around the booksellers’ and publishers’ websites, and bookstores: there are excellent books not on any prize shortlist.*) The Wellcome Trust, one of largest medical research … Read More

Yet another fluoride-IQ study - Open Parachute

Ken Perrott Jan 31, 2018

As with most of these fluoride-IQ studies this one is only relevant to areas of endemic fluorosis (This is from a UNESCO paper and has been corrected for New Zealand. Identification of fluorosis in a country does not imply the whole country is high fluoride). Yes, it’s a bit like groundhog day. Another fluoride-IQ study – and we expect this to … Read More
