Lasers shooting into irises

Byoliveridley

I did not think my first minor surgery would involve someone shooting lasers to make holes in my iris. It sounds like more fun than it actually was, but was mostly painless and here I am, looking at a computer screen 3 hours later. My eyes feel like they’ve had about 5 hours of sleep, which is good considering they’re now sporting two brand new drain holes.

Laser iridotomy is also performed prophylactically(preventively) on asymptomatic individuals with narrow angles and those with pigment dispersion. Individuals with a narrow angle are at higher risk of an acute angle closure, especially upon dilation of the eye

I also just started reading Bad Science by Ben Goldacre, which is about the use and misuse of the banner of science by a large group of people including nutritionists, pharmaceutical companies and “alternative” treatment specialists. It has a great chapter on the “placebo” effect, how much of it is culturally mediated, and how much doctor demeanour and confidence in their skills and outcome affects results. The doctor shooting holes in my eye was extremely confident in their skills and their results, and normally, my brain would be sending off all kinds of hubris warnings. In this case, their confidence reassured me a bit, and Bad Science definitely helped. It was also interesting to see a large section on homeopathy in the book, since I’ve written about my contact with homeopathy and felt that the cultural practices of a good homeopath can be of some use to people as long as they don’t go too far. The book confirmed some of that.

  • Tracking my mail

    Byoliveridley

    On the sidebar, you will find a new donut chart which is a simple cumulative count of the mail we get at home. The measurement started on the 19th of March, 2012, so not much data yet 🙂  Useful – Mail I will find useful (yes, including bills). Solicited – Mail I find marginally useful, but comes from organisations I support, so I guess it is okay? Junk – Well, you know it when you see it; RTS – Return to Sender, addressed to previous occupant. Canada Post charges quite a bit for mail forwarding, whereas the USPS does it free for a year, so people get better at updating addresses and not missing a couple. I have lived in my current place for 18 months now, still get mail for multiple different people.

    My Mail

    No particular reason to do this, I was just curious, and this article about the US postal service starting to solicit more direct mail (what most people regard as junk) customers just triggered me to post the results online. My perception is that the signal/noise ratio on my mail is very low, let’s see… The underlying data is in a simple google spreadsheet and the image is linked dynamically, so should always be current.

    Update: I don’t have a red dot on my mailbox, no particular reason, just supporting my economy and increasing the GDP, perhaps? More seriously, I would like a green dot campaign, where unsolicited mail is not welcome unless I place a green dot on my mail box for all unsolicited mail, and an amber dot for not-for profit, advocacy, political and generally non-commercial mail.

    Update:  Not tracking my mail any more, as you can see. It was remarkably stable at around 58-50% “junk”. Interesting…

  • Leaving Chapel Hill

    Byoliveridley

    I’ve lived in Chapel Hill for over 10 years, encompassing a Ph. D, a marriage, a few jobs, cats, many wonderful friends and a blog that to this day proceeds in fits and starts. But, my time here is finally at an end. I accepted a job offer to move to Victoria, BC. It’s on Vancouver Island and quite breathtakingly beautiful in an almost throwaway fashion!

    Photo Courtesy flickr – Allie Wojtaszek’s photo stream.

    I am not kidding, the island’s just incredibly beautiful.

    Anyways, I will be heading out for a long vacation in Chennai, back for 10 days or so, then leaving end of March to start work. Blogging for the next week or so should be normal (as in, no rhythm, rhyme or reason!). Once I get to Chennai, blogging will be sporadic as my parents don’t have internet and I am too lazy to set up a connection for a month!

    Once I get to Victoria, blogging will, of course, resume, though I guess I’ll still remain pseudo anonymous (not that too many people care!). I will be working for a company that works very closely with the EPA and Environment Canada and things get delicate when you work with the government and criticize them! It will be interesting to see where this blog goes, though I will refrain from the usual gee whiz look at that beautiful scenery posting!

    If you know people on Vancouver island you can hook me up with, please email /leave a comment. I don’t move that often, and I can’t rely on seeing familiar faces on Franklin Street and the Weaver Street Market any more!

    S. is staying in Chapel Hill for a little longer, she loves her work and just started it!

    It’s been fun living here, but all good things must pass.

  • Melamine – The FDA Says the Right Things

    Byoliveridley

    But can it follow up?

    FDA limits Chinese food additive imports – USATODAY.com

    The Food and Drug Administration is enforcing a new import alert that greatly expands its curtailment of some food ingredients imported from China, authorizing border inspectors to detain ingredients used in everything from noodles to breakfast bars.

    The new restriction is likely to cause delays in the delivery of raw ingredients for the production of many commonly used products.

    Inspectors are now allowed to detain vegetable-protein imports from
    China because they may contain the chemical melamine. Melamine, used in
    the manufacture of plastics, was found in the wheat gluten and rice
    protein concentrate that has led to the recall of 5,300 pet food
    products.

    Good, and about time. The FDA cites “control issues” in issuing this alert.

    Now for the products to reach U.S. foodmakers, the importers will have
    to prove to the FDA that they are safe. The ingredients restricted
    include wheat gluten, rice gluten, rice protein, rice protein
    concentrate, corn gluten, corn gluten meal, corn by-products, soy
    protein, soy gluten, mung-bean protein and amino acids.

    Excellent stuff, exactly what was needed, to put the onus on the manufacturer to prove safety. Here’s the FDA’s press release.

    The onus, of course, is on enforcement. Can the FDA identify every item on this list, and quarantine it until a certificate is produced? Can it subject a random number of these products to independent verification to avoid cheating? Does it have the resources? Does it have the inspectors? Stay tuned.

    Melamine – now in Pigs

    Byoliveridley

    The pet food recall gets scarier. The FDA does not have this issue under control. It is not a conspiracy to hide anything, it’s just the pace at which the FDA operates, and its lack of mandate to really regulate animal feed.

    Pet Foods May Have Been Intentionally Poisoned

    The FDA and Agriculture Department also were investigating whether some pet food made by one of the five companies supplied by Wilbur-Ellis was diverted for use as hog feed after it was found unsuitable for pet consumption.

    “We understand it did make it into some hog feed and we are following up on that as well,” Sundlof said.

    Later Thursday, California officials said they believe the melamine at the quarantined hog farm came from rice protein concentrate imported from China by Diamond Pet Food’s Lathrop facility, which produces products under the Natural Balance brand and sold salvage pet food to the farm for pig feed.

    “Although all animals appear healthy, we are taking this action out of an abundance of caution,” State Veterinarian Richard Breitmeyer said in a statement. “It is unknown if the chemical will be detected in meat.”

    Officials are investigating American Hog Farm’s sales records to determine who may be affected by the quarantine, said Steve Lyle, a spokesman for the California Department of Food and Agriculture. The 1,500-animal farm operates as a “custom slaughterhouse,” which means it generally does not supply meat to commercial outlets.

    “Mostly it is not so-called mainstream pork. This is an operation that sells to folks who come in and want a whole pig,” said Lyle said.

    Officials urged those who purchased pigs from American Hog Farm since April 3 to not consume the

    Well, the issue is not the safety of the melamine contaminated pork, the risk to humans is possibly low. The problem is that these ingredients are out of control, and unaccounted for, and being diverted to places they should not be. The systemic flaws are many, and I hope the FDA will issue some new guidelines to tighten up animal feed standards.

    Another tidbit:

    FDA officials would not release the names of the other two manufacturers that Wilbur-Ellis supplied, citing its ongoing investigation

    Is it just me, or does this always happen on a Friday???

    Monsanto Ashamed of Selling Bovine Growth Hormone

    Byoliveridley

    Why else do they not want people to know that their product is being used? You would think that Monsanto with its millions in profits and its monopoly in bovine growth hormone, would let the free market decide whether people want their ice cream/milk rBGH free or not. Surely, wouldn’t Monsanto’s commanding market presence, and the simple fact that conventional milk supplied by hormone injected cows tends to be cheaper than rBGH free milk be a sufficient counterweight against a simple rBGH free label?

    The ice cream maker has joined a national campaign to block what critics say is an effort driven by Monsanto (MON), which markets recombinant bovine somatotropin, or rBST, also known as recombinant bovine growth hormone, or rBGH.The hormone, which was approved by the Food and Drug Administration to boost production in dairy cows in the early 1990s, was not approved in Canada, Japan or the European Union, largely out of concern it may be harmful to animals.A newly formed dairy producers’ group, backed by Monsanto, is pushing for labeling changes, saying hormone-free labels imply that the milk is safer than other milk, when they say it’s not.

    Ben & Jerry’s in fight over hormone labeling – USATODAY.com

    This is a classic strawman’s argument. I don’t know if there is sufficient evidence to show that hormone filled milk is harmful to humans, but there is sufficient evidence that it is harmful to cows. As always, I point to the Meatrix (Note, available on youtube as well, but embedding has been disabled…).

    Here’s a letter from the Oregon Physicians for Social Responsibility summarizing the harmful effects of rBGH.

    1. Increase in IGF-1 levels – possible link to cancer in humans
    2. Mastitis in Cows – Do you want your breasts infected and painfully inflamed? That’s what RBGH does to cows
    3. Antibiotics Resistance – To combat mastitis, the cows are pumped with antibiotics, which end up in the solid waste, and water runoff.
    4. 15 other side effects in cows, bad enough that Canada and the EU do not permit this growth hormone

    All right, the product is still legal here in the US and I absolutely respect Monsanto’s right to sell it, fight for it and conduct a vigorous product defense (including obligatory astroturf group rbstfacts). But stop trying to get the government to do your dirty work for you and “banning” companies from telling consumers that they did not use your product, it’s shameful and unnecessary.

    Consumers have a right to pay premium for a product that they think is superior for one reason or the other. It is anti-free market and protectionist to restrict information that will help these consumers decide.

    What next? We all know that cosmetics tested on animals are not more harmful to people than animal cruelty free cosmetics. Shouldn’t that label be banned as well?

    Asbestos stays off global dangerous-substance list

    Byoliveridley

    NDP MP Pat Martin said Tuesday the Canadian delegation did not even participate in the discussions this year but got others to work on their behalf instead.

    He accused the Canadians of browbeating developing nations such as India, Pakistan and Vietnam — some of Canada's largest chrysotile customers — into opposing its inclusion on the list.

    "It's not a proud day for our country," said Martin, who attended the convention and spoke by telephone from Rome.

    Canadians can now breathe easy. The government did not even have to oppose a notification officially, other countries did it for them.
