Cochrane is Starting to ‘Get’ SBM!
This essay is the latest in the series indexed at the bottom.* It follows several (nos. 10-14) that responded to a critique by statistician Stephen Simon, who had taken issue with our asserting an important distinction between Science-Based Medicine (SBM) and Evidence-Based Medicine (EBM). (Dr. Gorski also posted a response to Dr. Simon’s critique). A quick-if-incomplete Review can be found here. One...
What does a new drug cost?
Despite the variety of health systems across hundreds of different countries, one feature is near-universal: We all depend on private industry to commercialize and market drug products. And because drugs are such an integral part of our health care system, that industry is generally heavily regulated. Yet despite this regulation, little is publicly known about drug development costs. But aggregate research and...
Can Vitamin C Induce Abortion?
Editors Note: This is a guest contribution from two medical students, one from Chicago and one from Queensland. If you like their work, we’ll consider having them write more for us. Authors: Drey Pavlov UQ-Ochsner University of Queensland School of Medicine Igor Irvin Bussel Chicago Medical School Rosalind Franklin University of Medicine and Science In hopes of joining the SBM movement as...
The Hazards of “CAM”-Pandering
Steven Salzberg, a friend of this blog and Director of the Center for Bioinformatics and Computational Biology at the University of Maryland, is on the editorial boards of three of the many journals published by BioMed Central (BMC), an important source of open-access, peer-reviewed biomedical reports. He is disturbed by the presence of two other journals under the BMC umbrella: Chinese Medicine...
The benefits and risks of folic acid supplementation
Could a vitamin with proven benefits in one group cause harm to another? That’s the growing concern with folic acid, the vitamin that dramatically reduces the risk of neural tube birth defects such a spina bifida. Studies designed to explore the possible benefits of folic acid for heart disease, stroke and cancer are giving out some worrying signs: At best, folic acid...
EMDR and Acupuncture – Selling Non-specific Effects
The scientific approach to understanding the world includes the process of carefully separating out variables and effects. Experiments, in fact, are designed specifically to control for variables. This can be especially challenging in medicine, since the body is a complex and variable system and there are always numerous factors at play. We often characterize the many variables that can influence the outcome...
Ethics in human experimentation in science-based medicine
Science-based medicine depends upon human experimentation. Scientists can do the most fantastic translational research in the world, starting with elegant hypotheses, tested through in vitro and biochemical experiments, after which they are tested in animals. They can understand disease mechanisms to the individual amino acid level in a protein or nucleotide in a DNA molecule. However, without human testing, they will never...
Of SBM and EBM Redux. Part IV, Continued: More Cochrane and a little Bayes
OK, I admit that I pulled a fast one. I never finished the last post as promised, so here it is. Cochrane Continued In the last post I alluded to the 2006 Cochrane Laetrile review, the conclusion of which was: This systematic review has clearly identified the need for randomised or controlled clinical trials assessing the effectiveness of Laetrile or amygdalin for...
Critique of “Risk of Brain Tumors from Wireless Phone Use”
Following my recent critique here of the book Disconnect by Devra Davis, about the purported dangers of cell phones to health, David Gorski asked me to comment on a recently published “review article” on the same subject. The article is entitled “Risk of Brain Tumors from Wireless Phone Use” by Dubey et al [1] published in the J. Comput Assist Tomography. At...
