  • Smokers—what should we do with them?

    We sometimes treat them like second-class citizens. Or do we? Certainly smokers hate it when we force them out into the cold for a butt. Here in Michigan, we’re thinking about restricting smoking in a lot of public places. There benefits are supposed to accrue to three groups: the smokers themselves, their co-workers who are exposed to second-hand smoke, and the public, who pays more for health care because of smoking.

    I asked a simplistic question once about whether smokers should pay higher insurance premiums, that doesn’t really bring the same benefits to everyone as a more comprehensive approach. Now, outlawing smoking altogether seems foolish—you know, prohibition, black market, etc. But is it unreasonable to limit smoking to, essentially, the someones own private space?

    How do we justify a potential limitation of individual liberties? Smoking is the biggest cause of premature (and preventable) death in the U.S., leading to about half-a-million deaths yearly. Data from 1998 showed smoking was responsible for about 76 billion dollars in health care expenditures, plus productivity loses of about 92 billion dollars per year. Smoking sickens and kills people, and costs are (very crappy) economy a lot of money. For both economic and public health reasons, we must make smoking cessation a paramount societal goal.

    How do we do this?

  • Denialists' harvest—the AIDS body count in South Africa

    As a physician, few things frustrate and sadden me as much as preventable deaths. I see it all the time—the guy who kept putting off his colonoscopy and was later diagnosed with metastatic colon cancer, the woman who put off coming to the doctor with her breast lump until it broke through her skin, the heart patient who couldn’t stop smoking. They all haunt me. But what if the ghosts were numbered in the hundreds of thousands rather than dozens?

    That’s what it must be like to be Thabo Mbeki, that is if he has a conscience. It may (or may not) be bad “framing” to call someone a “denialist” but a new study seems to say that whatever you call it, denialism kills. When government leaders allow themselves to be duped by denialists murderers non-acceptors of truth sickfuckdenialistbastards….Damn it, I’m sticking with “denialist”. When government leaders allow denialists to guide their public health policies, people die, apparently in large numbers. I’ll have to leave it to my epidemiology colleagues to evaluate the quality of the study (which on my read looks OK), but even if it’s off by one order of magnitude, the results are horrifying.

  • NCCAM: the not-even-wrong agency

    The National Center for Complementary and Alternative Medicine (NCCAM) is a government agency tasked with (among other things), “[exploring] complementary and alternative healing practices in the context of rigorous science.” In this space we have talked about NCCAM quite a bit, but I have to admit that I don’t think about them very much. The other day, though, I was reading though JAMA and I came across a study funded by the agency. The study, which showed that Ginkgo does not prevent Alzheimer’s-type dementia, was pretty good, so I cruised on over to NCCAM’s website to see what else they’ve been up to.

    A quick glance at NCCAM’s front page:

      “Ginkgo Evaluation of Memory (GEM) Study Fails To Show Benefit in Preventing Dementia in the Elderly”
      “CAM and Hepatitis C: A Focus on Herbal Supplements ‘No CAM treatment has yet been proven effective for treating hepatitis C or its complications.’”
      “Selenium and Vitamin E in Prostate Cancer Prevention Study, ‘selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer.’”

    It seems that NCCAM is finding out something we already strongly suspected: improbable medical claims are usually wrong. Since that’s not how they see things, and since I don’t believe that there is such a thing as alternative medicine, I was curious how they defined CAM.

  • What does your health insurance cover?

    For many Americans, it’s open enrollment time, the period your employer give you to make changes in your health insurance coverage. You may not understand your insurance very well, but you have to understand this one important fact: your health care providers know even less about your insurance than you do. Most doctor’s offices have a sign that says something like, “Your insurance is your business.” There is know way for your doctor’s office to know all the details of all the different insurance plans.

    Each state has different rules, and each part of the country differs in what kind of health plans predominate. In some areas, non-coverage is so common that it almost doesn’t matter what you know, other than the location of a free clinic. But for those of you looking at new or existing health plans, you must read through the documentation, especially the summaries that tell you what is and isn’t covered.

    For example, many plans cover a yearly preventative physical. Many do not. If you don’t tell your doctor whether or not preventative services are covered, you may end up with an unexpected bill. Preventative physicals are often covered without a co-pay, but most other visits do have a co-pay.

    Your plan will include a glossary, but some terms deserve special attention.

  • Ginkgo does not prevent dementia, or "I can't remember what NCCAM is good for"

    ResearchBlogging.orgHere’s a question for you: is there, or should there be, any difference between studies of “alternative” and non-alternative medicine? I’ve argued before that there is no such thing as alternative medicine. So why do we need a separate agency to study “alternative” medicine? The National Center for Complementary and Alternative Medicine seems to be just such an agency. For example, the latest study of Gingko biloba for the prevention of dementia could have been funded by other agencies, such as NIMH. Why NCCAM?

  • Se Habla "woo-woo"

    So, America is changing. We have an African American president. The Latino population continues to grow. How can the alternative medicine community adjust to this demographic shift? What are they to do?

    I’m glad you asked! It turns out that immigrants are palomas ripe for the plucking. Now, we’ve talked about the ethics of alternative medicine, and how “meaning well” is not exculpatory. If you promote quackery, it’s wrong, even if you believe your own drivel.

    One of the worst types of drivel is naturopathy. This “specialty” advertises itself as “medicine-plus”, but really it’s “healing-minus”: minus the evidence, minus the training, minus intelligent thought.

    It should be no surprise that recent immigrants, who may have low educational levels, especially in English, and have less access to the health care system financially, culturally, and linguistically should be ripe targets.

    And targeting these vulnerable individuals is a naturopathic “doctor” in Connecticut.

  • And now for something completely different

    I’m trying a new thing. I think it would be nice to have a place where medical professionals, and those who wish to see how those professionals are thinking, can have frank discussions about medicine, altmed, etc. In support of this, I’ve created a new forum. The idea is to enhance discussions about medicine, medical ethics, and related issues, and enable people to start their own topic that might not have shown up on the blogs.

    I’m hoping that the discussion can compliment what is already happening right here.

    The catch is that I’m going to have a more aggressive moderation policy than I would be comfortable with here. Trolling, abusive behavior, etc. will be verbotten. Anyway, it’s super beta, so feel free to come by and check it out.

  • Abdominal adiposity and risk of death, or "belly fat'll kill ya'"

    ResearchBlogging.org

    Last week’s New England Journal of Medicine gave us some remarkable news, via the JUPITER Trial, adding additional evidence to the pile of articles on the cardioprotective effects of statins. This article is getting lots of press, which is great, but I’d hate to see this week’s edition of the Journal get lost. Specifically, there’s a huge population-based study on obesity and mortality. We’ve explored previously the dangers of obesity, and we’ve been fought the whole way by various denialists.

    Earlier studies have shown associations between excess body weight (as measured by body mass index (BMI)) and death, but this study did a few things differently. The latest study in the Journal, titled “General and Abdominal Adiposity and Risk of Death in Europe”, takes a look at a larger data set, and takes a closer look at different measures of obesity.

  • Why male circumcision and female genital mutilation are not morally equivalent

    NB: Believe it or not, I actually had to close comments, the first time I’ve ever had to do it. They had become so offensive without any useful content that it’s no longer worthwhile to keep it going. Sorry.

    I have repeatedly vowed to stay away from this topic, but in defense of my colleague, I must speak out. Harriet Hall, from sciencebasedmedicine.com wrote a brief piece examining the medical literature regarding male circumcision. As part of the discussion, she mentioned having performed many of these procedures during an earlier part of her career. In response to her interesting post, she received comments such as this one:

    Dr. Hall needs to confess her guilt for the intentional injury of scores of infant males and reexamine her motives in writing this document.

  • Stop the RFK Jr. appointment NOW

    I would beg everyone who reads the scienceblogs and cares about science to contact the transition team in the Obama administration as Orac has requested.

    It should be clear by now to readers of this blog that pseudoscience is not a problem of just the right. The left wing areas of pseudoscience are just as cranky, just as wrong-headed about science, just as likely to use the tactics of denialism to advance a non-scientific agenda. We have been dealing with the denialism of the right more because they’ve been in control. Now is the time to nip the denialism of the left in the bud so it doesn’t take root in this new administration.

    RFK Jr. is a crank (Orac for more), and one of the problems with cranks is Crank Magnetism. When people have one type of pseudoscientific belief it tends not to be isolated. Instead it reflects a general incompetence in understanding science, evaluating the quality of evidence, and what constitutes good science. RFK Jr.’s crankery will not be limited to vaccines and autism. He will undoubtably become the poster boy for all sorts of left wing crankery – be it environmental extremism, toxin/radiation paranoia (we’ll never get public wifi), or his already well known anti-vax crankery.

    My letter to the transition team is below the fold. Please join me in trying to prevent this terrible error on the part of the Obama campaign.
