Vaccinations and autism: are we number 1?

It has been alleged by Great Minds such as Jenny McCarthy that the US recommends far more vaccinations than other countries.  Her precise statement was, “How come many other countries give their kids one-third as many shots as we do?” She put this into the context of wondering if our current vaccine schedule should be less rigid.  The entire piece was filled with what could charitably called less-than-truthful assertions, but examining simply this one assertion might be useful.  Dr. John Snyder has an excellent analysis of the most important assertion, that of the possible benefits of an “alternative vaccination schedule”  which I would encourage you to read.

First, we need to parse out this “more shots than everyone else” statement.  Some countries–Haiti, for example–give far fewer vaccines due not to fewer recommendations but to adverse economic conditions. Because of this, they have very high rates of vaccine-preventable diseases.  They want to vaccinate more, but can’t.  Then there are countries who can afford to vaccinate. Let’s look at what three industrialized nations recommend before six years of age.

Vaccinations, by disease and country, 0-6 years of age

Vaccine FranceGermanyUSAIceland
Hepatitis BYesYesYesNo
RotavirusNoNoYesNo
Diphtheria, tetanus, and pertusisYesYes YesYes
HibYesYesYesYes
PneumococcusYesYesYesNo
PolioYesYesYesYes
InfluenzaNot reportedNot reportedYesNo
Meales, mumps, rubellaYesYesYesYes
VaricellaNoYesYesNo
Hepatitis ANoNoYesNo
BCG (disseminated TB)YesNoNoNo
MeningococcusNoYesFor someYes

The chart, as I’ve presented it, is somewhat imprecise.  Some vaccinations are given in a single shot, others in multiple shots, but these generally represent the childhood vaccinations in each country, and the links provided will take you to the more detailed information. 

If I understand Dr. McCarthy correctly, she is using the alleged difference in national vaccine recommendations to show that it is safe to vary vaccination schedules by some method or another.  I would not disagree: vaccination schedules should not be immutable but should (and do) change based on available evidence. But changes should not be based on one or another person’s “feelings”. 

The other implication is that other countries, by having one-third fewer vaccinations (sic), will have lower rates of autism.  She bases her assertions about international vaccination rates and autism on a report self-published by her anti-vaccination group Generation Rescue.  In this screed, they allege that the number of “mandatory vaccines” are much greater in the U.S. (there are no “mandatory” vaccines in the US, only those that are recommended or those required for various jobs or schools).  It’s not clear to me how they arrive at their numbers.  Perhaps they count the total number of vaccinations given for each disease (i.e., each DPT counts as three vaccinations, given five times for “15 vaccinations).  Using this method, by my count France “mandates” 35 vaccinations by year six (they report 17) and the U.S. has 36, as they reported.  But this isn’t the counting method they say they used.  In the footnotes they say that:

All vaccine schedules are as of 2006. Some countries use combination vaccines. All schedule counts have been
normalized to compare to the US schedule. For example, if a country uses an MMR-Varicella combination vaccine, it
counts as “2” vaccines.

The report then goes on to try to link these supposedly vastly different vaccine schedules to supposedly vastly different autism rates in the EU vs. the U.S. (If you understand their “methods” better than I do, feel free to explain in the comments.)

European autism statistics are scarce, but high end estimates place them at up to 63/10,000, or 0.9/150, compared to a US estimate of 1/150.  This is hardly a smoking gun, and the “study’s” so-called multipliers are simply error multipliers, given the large range in prevalence estimates.

Jenny McCarthy’s senseless ramblings on health are based on more formal senseless ramblings from a special interest group whose “special interest” appears to be the promotion of infectious diseases.

#ShowMeMyServer 2.0

Kevin HazardA few short months ago, we took transparency to the next level by opening the doors for customers to request a picture of their actual server on a rack in our data centers. Without question, our first “Show Me My Server” experiment was a huge success. We were sure the program would be reborn, and we took a few notes about how we could improve it.

Enter #ShowMeMyServer 2.0.

We heard from a few of our international customers that the narrow time frame fell in the middle of their night. This go-round won’t be limited to a single hour … we’ll accept entries for a full 24 hours, giving every time zone an equal shot at participation. In our first run, we also made a disclaimer about the quality of the photographs, as some were snapped by Blackberries and iPhones … this time, we’ll be using a DSLR camera with hopes of getting some higher quality images back to you. That last update should be reason enough for everyone who participated the first time to enter again. :-)

With the extended participation window, we’re making it a little tougher to qualify, so we’ve got four simple tasks for you to complete within one day – by 3:30 p.m. CDT on March 24. ALL FOUR tasks must be completed before we give your server a well-deserved close-up.

Your Mission (you should choose to accept it):

  1. Post a Tweet saying “I’m Powered by @ThePlanet. #showmemyserver”
  2. Post a comment on this blog that includes “My website is _________, and I’m Powered by The Planet.”
  3. Become a fan of The Planet on Facebook: http://www.facebook.com/theplanet
  4. Send an email to twitter @ theplanet.com with the following:
    1) Your name:
    2) Twitter username:
    3) Account number (C—– or E—–):
    4) The IP address of the soon-to-be-photographed hardware:
    5) The name you want displayed in your picture:

The information above – along with the address you send your email from – will be used to verify your account. The IP address you include will not be publicized or included in your server’s photo, its only purpose is to pinpoint your server. If you do not include a display name in your email, we will include your Twitter username by default.

As we did in our first #showmemyserver, we’re limiting each customer to picture of a single server. If you have a private rack, we can make an exception and snap a couple pictures of the servers on your rack if you’d prefer. Just provide your rack number in place of the server’s IP address in your email.

Once we close the submissions window, we’ll start snapping the photos. The turnaround will depend on the volume of requests. We’re aiming to get pictures back to you — replying to the e-mail you sent twitter@theplanet — by the end of next week. While getting a picture is not the same as meeting your server face-to-faceplate, it’ll at least tide you over until you can make it to Houston or Dallas for an “in real life” data center tour.

When you finish your tasks and start waiting for your picture, head to our new Flickr group at http://www.flickr.com/groups/showmemyserver/ and show us your computer or workstation … it’ll be interesting to see if the servers look as similar as some pets look to their owners.

What are you waiting for? Get going!

-Kevin

Update: As of 3:31 p.m. CDT on March 24, comments are closed. Participants, get ready for your server’s close-up!

From ArcGIS to Web Maps: Simple Techniques for Publishing GIS Maps Online by Emily Wilson of the University of Connecticut Center for Land Use Education and Research

Date: 
Thursday, April 22, 2010

From ArcGIS to Web Maps: Simple Techniques for Publishing GIS Maps Online by Emily Wilson of the University of Connecticut Center for Land Use Education and Research (April 22, 2 pm US EDT/11 am pm US PDT).  There are a variety of ways to serve maps and geospatial information on the web, and they range from the very simple to the advanced.  This webinar will cover a variety of simple tools for putting static maps on the web.  The webinar will start with the very basic technique of screen captures and pdfs and move to other useful tools such as the mapbook tool for ArcMap, the image mapper tool for ArcMap and, finally, geographically enabled pdfs.  Attendees will not likely use all the tools presented, but may find one or two to be the perfect solution.  Each tool will be explained, and sample output will be shown. 

This webinar is co-hosted by the EBM Tools Network, the University of New Hampshire Cooperative Extension, and the University of Connecticut Center for Land Use Education and Research.  Register for this webinar at www1.gotomeeting.com/register/469800593

 

NCBI ROFL: The locomotion of dairy cows on concrete floors that are dry, wet, or covered with a slurry of excreta. | Discoblog

2864838911_e0772dbabd“Six dairy cows were trained to individually walk down a concrete aisle for a food reward. Their locomotion was then examined in a switchback experiment as the floor surface of the aisle was changed from dry to wetted concrete or concrete covered by shallow (5 cm) or deep (12.5 cm) slurry from cattle excreta…  Cow locomotion was measured over the second half of the aisle, and limb angles recorded as the cow passed a video camera. Wetting the floor did not affect the walking or stepping rate, but it reduced the arc made by the joints of the hindlimb during the supporting phase. Slurry caused the cows to keep their legs more vertical at the end of the support phase, probably to aid lifting the limb out of the slurry. It also caused the cows to place their forelimbs down less vertically at the start of the support phase, probably because of the reduced risk of slip in the slurry. When the floor was covered with either the deep or, to a lesser extent, the shallow slurry, the cows’ walking and stepping rates were reduced, and on the floor covered with deep slurry their step length was increased. Therefore slurry reduces the cow’s walking speed and alters limb angles during the support phase, producing a different walking pattern from cows on dry or wetted concrete.”

In Search of the Mind’s Eye | The Loom

Writing about the brain can sometimes bring me amazingly close to my readers–so close that I feel like I’m inside their minds. Case in point: my new column for Discover, on the subject of the mind’s eye.

Here’s how it begins:

One day in 2005, a retired building surveyor in Edinburgh visited his doctor with a strange complaint: His mind’s eye had suddenly gone blind.

The surveyor, referred to as MX by his doctors, was 65 at the time. He had always felt that he possessed an exceptional talent for picturing things in his mind. The skill had come in handy in his job, allowing MX to recall the fine details of the buildings he surveyed. Just before drifting off to sleep, he enjoyed running through recent events as if he were watching a movie. He could picture his family, his friends, and even characters in the books he read.

Then these images all vanished. The change happened shortly after MX went to a hospital to have his blocked coronary arteries treated. As a cardiologist snaked a tube into the arteries and cleared out the obstructions, MX felt a “reverberation” in his head and a tingling in his left arm. He didn’t think to mention it to his doctors at the time. But four days later he realized that when he closed his eyes, all was darkness.

I describe the singular case of MX, and what he tells scientists about our mind’s eye. The original paper that inspired the column compared MX to a group of normal men of his age and profession to figure out what was unique about him. But to my surprise–and to the surprise of the scientists I wrote about–a lot of readers felt a great kinship with MX.

Discover is running a selection of letters to the editor about the column, and a response from the scientists. It won’t be available online, but I was so fascinated by the exchange that I’m reprinting it here.

In March’s “The Brain” [page 28], Carl Zimmer assumes that having a mind’s eye is a normal function of the human senses. Yet I have never had a mind’s eye, and when I bring this up in conversation others often voice the same complaint. How common is this?
Marshall Krause San Geronimo, CA

Neuroscientists Adam Zeman and Sergio Della Sala reply:
We have encountered people who report that they have never experienced imagery; they seem little if at all disabled by their deficiency. We hope to study this neglected phenomenon using psychological and brain imaging techniques like those with which we explored the case of MX. Such research may help explain both the basis of imagery production in the brain and how (if at all) imagery is useful to us.

I enjoyed reading about MX and his mind’s-eye blindness. Were MX’s dream experiences also affected by this affliction?
Arlene Barker Homer City, PA

Zeman and Della Sala reply:
For about a year after the loss of his mind’s eye, MX reported that he dreamed without visual imagery. But then his visual dreaming recovered at night, even though his mind’s eye remained blank by day. This suggests that the brain mechanisms involved in dreaming can be teased apart from those involved in deliberate imagery formation.

Sex in the Woods: an Unintelligent Response

This is a perfect example of how people don’t think about the consequences of their actions when it comes to the environment.  I can’t imagine how bad the problem was to go to these lengths and why there was nothing else they could do about it. Six thousand trees!   This is what not to do if you have a human behavior problem. People need to think about what happens to the environment if forests are cleared, think about the whole ecosystem that is destroyed, and whether it’s a wise option.

6,000 Trees Axed to Prevent Sex in Forest

As many as 6,000 trees have been felled in a forest near a British town to prevent couples from having sex there, a media report said.

Trees cut along the A666

The trees were hacked at the 12-hectare site on the outskirts of Darwen, Lancashire, after a “health and safety survey”, Daily Express reported on Tuesday. Officials say the forest that runs for kilometres along the busy A666* was cleared as some of the trees, planted after the Second World War, were in danger of falling.

Police and councillors have, however, confirmed that another reason was to discourage strangers from the known “dogging” area. Dogging is a term for people having sex with strangers in public places, or watching others have sex, often in woods or country lay-bys.

Backlash

The felling of 6,000 trees to try to stop couples having sex there has prompted an angry backlash. “It’s awful that a public green space, an asset to the local community, has been destroyed mindlessly. If the law was enforced properly then there would be no need to chop down these trees,” Matthew Elliott, chief executive of the TaxPayers’ Alliance, was quoted as saying.

Alistair Foster, an environmentalist, said: “It is such a terrible thing to do. Old trees do not just fall down. What next, chop down 300-year-old oak trees in case they suddenly fall over one day? And to do it to reduce people having sex in the woods is farcical.” Terry Hardman, who travels past the clearance site every day, said that the work had “absolutely devastated the area.”

“There was a massive forest that’s been reduced to open space. Surely that can’t be good for the environmental situation?”

Sergeant Mark Wilson said that the sexual activities in the area were “an ongoing problem and very worrying for members of the public”. “It’s far too early to tell if cutting the trees back has had any impact on the dogging situation, but we’ll be paying regular attention to the area.”

Double whammy

“I’m more than happy this is being carried out and it has a double whammy in terms of the sexual behaviour. I’ve heard anecdotally that since the trees have been cleared it’s quietened down a lot,” ward councillor Jean Rigby was quoted as saying.

So if you have a problem in the trees cut them down, [...]
