Here is a recap of the stories that appeared last week at Science-Based Medicine, a multi-author skeptical blog that separates the science from the woo-woo in medicine.
A formal request for retraction of a Cancer article (James Coyne)
A plea for Cancer to retract an article claiming that psychotherapy delays recurrence and extends survival for breast cancer patients. It’s just another poorly conceived attempt to validate fanciful ideas about “mind over matter” in cancer treatment. Its conclusions are not supported by simple analyses, but only by the authors’ inappropriate multivariate analyses. The research design was flawed, there is no plausible mechanism to explain their results, it is essentially a negative study misrepresented as positive, and the authors attempted to block publication of criticisms.
Gary Taubes and the Cause of Obesity (Harriet Hall)
Gary Taubes wants everyone to adopt a low-carb diet. He offers a plausible rationale but admits that the evidence isn’t in yet. Whatever the underlying cause of obesity, there are practical ways to achieve weight loss by reducing calorie intake below expenditure while we wait for better evidence. Strict low-carb diets are one way to achieve lower total calorie intake and may be somewhat more effective than other diets in the short term, but they have not proven more effective in the long term.
Dialogue on “Alternative Therapies” (Steven Novella)
In an opinion piece in The New York Times, James Gordon represents many common misconceptions about mainstream medicine and CAM. Mainstream medicine does not “dictate” drugs and surgery, and nutrition and exercise are mainstream, not “alternative.” It is mainstream medicine, not CAM, that addresses underlying causes. The rising costs of health care can be best addressed by not wasting money on dubious treatments.
Legislative Alchemy 2014 (so far) (Jann Bellamy)
Legislative alchemy is the process by which legislators turn practitioners of pseudoscience into state-licensed health care professionals, unleashing quackery on the public. Recently, chiropractors have suffered some defeats; naturopaths have achieved licensing in two more states; acupuncture bills are pending; and Vermont has passed a “chronic Lyme disease” bill. You can track CAM-related bills in your state through a list maintained on the Society for Science-Based Medicine website.
More Dialogs (Mark Crislip)
Another response to Gordon’s opinions in The New York Times. Medicine has issues, but the solution is not to turn to therapies based on fantasy and magic. Dr. Crislip distinguishes 4 categories of SCAMS: magic, plausible, inadequately tested, and things that are not CAM at all, like diet and exercise. Gordon’s call for a dialog on CAM is only a distraction from effective efforts to improve reality-based practice.
