Bad Reporting on Acupuncture

http://www.flickr.com/photos/migrainechick/ / CC BY 2.0

So this article on the NewScientist website really chapped my ass.

It cites the publication of a new study that outlines successful use of acupuncture to treat spinal injuries induced in rats.  Now, I’m not a doctor, and I’m unable to access the full-text of the study in question.  My suspicions are that some qualified party will cite methodological issues, or more likely, the study will remain a footnote  in light of the overwhelming weight of evidence in favor of the interpretation that acupuncture possesses no therapeutic benefit beyond that of placebo. (Maybe not.  We’ll see, but I doubt it.)

From the article:

Acupuncture’s scientific credentials are growing. Trials show that it improves sensory and motor functions in people with spinal cord injuries.

Well, not really.  For a great review of the current literature regarding acupuncture and an even greater deal of irate bitching about a fishy article written by The YOU Docs, Drs. Mehmet Oz and Mike Roizen, I highly suggest reading an article on the subject written by Dr. Mark Crislip over at Science-Based Medicine.  In it he outlines the results of numerous systematic reviews of the medical literature as well as dubious claims made about the mechanisms by which acupuncture works its supposed magic.  It appears that Drs. Oz and Roizen are attracted to the mysticism surrounding traditional Chinese medicine.

(Harriet Hall has also written a very thorough overview of acupuncture.)

Furthermore, the scientific paper to which the NewScientist links in the blockquote (different than the paper the article is discussing) does not deal directly with traditional acupuncture but with electroacupuncture in which an electrical impulse is introduced to the nerve.  This is an actual intervention that will induce some type of physiological response and cannot be considered acupuncture as Dr. Crislip asserts in his piece.  It seems dishonest to equate the two since there is a big difference between simply placing a needle into someone’s skin and running an electrical current into their body.

Of further interest is another post by Dr. Steven Novella regarding the placebo effect, one of the more misunderstood health-related phenomenons due to the complexities of interpreting study results.  The standard perception goes like this:  you walk into the doctor complaining of pain, the doctor gives you a sugar pill that you think is a pain reliever, and because you believe you’ve received treatment, your brain responds in kind and ramps up the production of natural healers, presumably the immune system.  Viola!  You’re better, and you didn’t have to ingest any dangerous drugs.

As you’ll see when reading Dr. Novella’s article and the mostly excellent discussion on the comment board that follows, the placebo effect doesn’t really work that way.  Most of it can be chalked up to study artifacts, bad study design, and reporting biases on the part of both doctors and patients.  Without an objective way of measuring pain or nausea or other types of discomfort, many of these studies are hindered by the need for patients to fill out a pain evaluation, the results of which can vary greatly from study to study.

You’ll notice all of my links are from Science-Based Medicine.  So sue me.  They devote their time and energy to evaluating dubious claims and pseudoscience, and they are an absolutely fantastic resource for anyone interested in the complicated study of medicine.  At the very least, reading many of these posts should help elucidate why all-or-nothing claims made by various pseudoscientific outfits are silly and don’t incorporate a nuanced approach to the business of getting things as right as possible.

Norway’s Government Run via iPad

Running Norway's government via iPad.

Running Norway's government via iPad.

Jens Stoltenberg the President of Norway was in the United States for the recent nuclear sumit that President Obama was hosting, and as a result of Iceland’s Eyjafjallajokull volcano eruption wreaking havoc on air travel Stoltenberg has not yet been able to return to Norway.

Gizmodo reports that Stolenberg had been running Norway’s government via his iPad.

I’m not sure if this implies that the iPad is super awesome, or if running Norway is just super easy.

Bill Nye Cleans House

I used to watch Bill Nye the Science Guy when I was a kid, and his show stands as probably the earliest discernible science-related influence I can remember.

Imagine my disappointment when I happened across Brian Dunning’s post over at Skepticblog that discusses Nye’s recent promotion of a cleaning product called Ionator from the company Activeion.  Essentially, the company has recruited Nye to endorse a line of water ionizers the cheapest of which is priced at $169 and the science behind which is unproven and dubious.

I’m not going to get into the debate over the science of their claims.  You can scroll through the comments on Skepticblog, which do a decent enough job of hashing out the quandaries, and you can read an article by Dr. Stephen Lower, a retired chemist from the Department of Chemistry at Simon Fraser University in Vancouver, that Dunning links to and which discusses the general quackery of ionized water claimants and provides an interesting remedial chemistry lesson about the subject.

My overall impression is that at best, Activeion’s product is a ripoff that does what they say it does despite the fact that its effects could be achieved for a few dollars and without the aid of the ionizer, and at worst, it’s a pseudo-scientific scam.  (If you’re interested in specifics, I highly recommend reading the discussion.)

I don’t agree with Dunning’s reasoning that we should withhold judgment if Nye took up the job because of money woes.  If Bill Nye knowingly promoted snake oil, he has done so at the peril of his credibility within the skeptical community as a science advocate.  If he was duped, at least he wasn’t a witting scammer, but even so, it’s fair enough to say he should have vetted Activeion’s claims and checked with one of his many contacts that would have had access to pertinent knowledge.

Either way, my opinion of Nye is diminished.

Hal Heartley: On Why He Makes Indie Films

Indie film director Hal Heartley

I’m a huge fan of every single thing that filmmaker Hal Heartley has ever done. Today I decided that I wanted to try and buy some of his movies on DVD, or BlueRay. I started to look in all the usual places (Amazon, Deep Discount, and Heartley’s personal web site) and found that may of the films are out of print, which is very disappointing.

However, I also discovered a transcript of a speech that Heartley gave which I think is very interesting. Here is a clip from said speech.

The life of an independent filmmaker has something in common with that of an entrepreneur. These are people who have chosen not to, necessarily, have the security of a steady job, but whose work is to have ideas and try to get others as excited as they are about the possibility of these ideas. The entrepreneur might say: look, if we raise enough capital to buy these beautiful materials, we can build these houses with a nice view of the hills, sell them later on, and make some money for ourselves.

This is not unlike what a filmmaker sounds like when he or she says: if we raise capital to hire these beautiful actors and make this story about a boy, a girl, and their guns (or whatever) we might very well receive positive reviews and be accepted to film festivals, make our money back and maybe even a little more too. And, besides, we’ll be a little bit famous briefly.

The motivation is almost always this simple – to bring something into the world we want to exist.It might be, in our reckoning, Truth & Beauty (capitalized). Or maybe simply to make some money in a way that is more fun than working in a bank or being a construction worker.

I see now that I wanted to say I make movies for both of these reasons at different times. But, thinking about it while I prepared this speech for you, I understand this is not accurate. In fact, I am always operating in both these ways – trying to make something beautiful and true and make a living. I am not against money. But it is true: when push comes to shove and I have to choose, I tend to choose the insecurity of my independence over the security of money.

Often, one cannot have both – money and independence. Comfort, security, and cash is often purchased by giving up one’s independence. And by independence I do not mean a style of filmmaking or even a manner of doing business. Although it is that, a little. What I mean is an independent mind which refuses to give up the responsibility of reaching it’s own conclusions; independence as the acceptance of the responsibility to think for oneself.

After reading the speech I had several thoughts jump into my head. Here, in no particular order, are three of those thoughts.

1. Many people would argue that having money makes a person more independent, not less.

I’ve heard (I’m not sure if this is true mind you) that the last thing Bob Marley said to his son before he died was “Money can’t buy you life.” I’ve heard countless people say “Money can’t buy you happiness.”

One time I was at a bar talking about this very subject with a few people and the bartener chimed in saying, “I’ve been poor, and I’ve been not poor… Not poor is better.”

I personally see money as something that can be a lubricant to life. Money can’t make your life perfect, it can’t makey you happy all the time, and even though it can prolong life it can’t beat death. But it sure can make it easy to do things that you want to do… like traveling, or getting a dog, or issue of Sandman that will complete the run, etc. People don’t need such things, but such things sure do make life a bit more enjoyable.

But maybe I’m wrong about this. Maybe a person who just takes off with as little as possible is really enjoying life in ways that people who have money, and stuff, never will.

Thoughts?

2. This speech makes me think about art that is done for money as opposed to art which is done simply for the sake of creativity.

Can art which is made to make money be as “pure” as art which is just created because someone just needed to create it? Does money diminish art?

3. The speech made me think about the relationship between the 9-5ers and the 8-4am-ers…

Heartley’s films tend to attack the 9-5 lifestyle, and sing the praises of the bohemian (what I call the 8-4am) lifestyle.

Most of the great renaissance art was the direct result of partons like the the banking powerhouse known as the Medici family.

Is this biting the hand that feeds them?

Granted, I’ve heard many a 9-5er criticize the artists of the world as “slackers”, simply because they don’t conform to the consumerism that has become what passes for American “culture” now-a-days. Such people believe that artists oe them something, because they have money, and thus the ability to consume artwork as a commodity…. So maybe the artists do need to tell them expose them as the pompus asshats they are from time to time.

But ultimately don’t these two lifesytles exist in relation to one and other? Does one not give meaning to the existance of the other, simply by being the that which the other is not? (Does that even make sense?)

Iceland Makes Monty Python’s John Cleese Spend $.

The volcano that screwed up air travel!

The volcano that screwed up air travel!

The volcano which is erupting in Iceland forced a Monty Python star to take a $5,000 cab ride John Cleese, of the classic Monty Python’s Flying Circus comedy troupe, paid $5,100 for a taxi ride from Oslo in Norway to Brussels in Belgium. Known for his absurdist humor, notes Clive Irving at the Daily Beast, Cleese is “the perfect posterboy for the present situation.”

[Source: I found this out via digg, where there is a link to a list of 9 interesting things about this Volcano's eruption. The list is rather interesting...]

Cephalopods = Awesomeness!

cephalopods

Recently I’ve been reading about cephalopods, because they are IMHO super awesome.

The following is from a Wikipedia article about cephalopod intelligence.

The cephalopod class of mollusks, particularly the Coleoidea subclass (cuttlefish, squid and octopuses), are considered the most intelligent invertebrates and an important example of advanced cognitive evolution in animals… Unlike most other mollusks, all cephalopods are active predators… Crabs, the staple food source of most octopus species, present significant challenges with their powerful pincers and their potential to exhaust the cephalopod’s respiration system from a prolonged pursuit. In the face of these challenges, octopuses will instead seek out lobster traps and steal the prize inside. They are also known to climb aboard fishing boats and hide in the containers that hold dead or dying crabs.

As of 2009, the octopus is the only invertebrate which has been conclusively shown to use tools. At least four specimens of the Veined Octopus (Amphioctopus marginatus) have been witnessed retrieving discarded coconut shells, manipulating them, and then reassembling them to use as shelter.

Cephalopods also have AMAZING dexterity, as evidenced by their ability to do complex things like open up jars with screw on tops! Obviously humans, and other primates, can do this but…

unlike vertebrates [cephlalopods], the motor skills of octopuses do not seem to depend upon mapping their body within their brains, as the ability to organize complex movements is not thought to be linked to particular arms.

So… Yeah.

You think that cephalopods are awesome now too, huh?
