The future of the Science-based Medicine blog: SBM is recruiting new bloggers
It’s been a rather eventful week here at Science-Based Medicine. I apologize that I don’t have one of my usual 4,000 word epics ready for this week. I was occupied all day Saturday at a conference at which I had to give a talk, and Dr. Tuteur’s departure produced another issue that I had to deal with. Fortunately, because Dr. Lipson is...
Changing Climate, Changing Infections
I will state my bias up front. I am convinced by the preponderance of data in favor of man made global warming. At the most simplistic level, I can’t see how converting humongous tons of fossil fuel into C02 and dumping it into the the atmosphere cannot have effects on the climate. To my mind its like determining vaccine efficacy or evolution....
Homeopathy Gets a Reality Check in the UK
The House of Commons Science and Technology Committee (STC) has released a report, Evidence Check 2: Homeopathy, in which they recommend that the NHS stop funding homeopathy. The report is a rare commodity – a thoroughly science-based political document. The committee went beyond simply stating that homeopathy does not work, and revealed impressive insight into the ethical, practical, and scientific problems caused...
Chronic Fatigue Syndrome and Retroviruses: Jumping the Gun
When I first heard that a retrovirus had been identified as a possible cause of chronic fatigue syndrome, I withheld judgment and awaited further developments. When I heard that two subsequent studies had failed to replicate the findings of the first, I assumed that the first had been a false alarm and would be disregarded. Not so. It’s a classic case of...
Autism Onset and the Vaccine Schedule – Revisited
This week on Science-Based Medicine I wrote an article about a new study looking at the onset of autism symptoms, showing that most children who will later be diagnosed with autism will show clear signs of autism at 12 months of age, but not 6 months. This is an interesting study that sheds light on the natural course of autism. I also...
Longing for a past that never existed
There once was a time when all food was organic and no pesticides were used. Health problems were treated with folk wisdom and natural remedies. There was no obesity, and people got lots of exercise. And in that time gone by, the average life expectancy was … 35! That’s right. For most of human existence, according to fossil and anthropological data, the...
The Early Course of Autism
Understanding the natural history of a disease is an important framework to have. It not only is critical for prognosis, but also informs us about diagnostic and screening strategies, is important to assessing interventions, and provides clues to causation. There has been much debate about the early course of autism, specifically the earliest age at which autism may be detected. At present...
Changing Your Mind
Why is my mind so clean and pure? Because I am always changing it. In medical school the old saying is that half of everything you learn will not be true in 10 years, the problem being they do not tell which half. In medicine, the approach is, one hopes, that data leads to an opinion. You have to be careful not...
CardioFuel—another magic pill
I get a lot of email asking me about various alternative therapies and supplements. A recurring theme on this blog has been the hyperbolic claims of alternative practitioners and supplement makers, and while I can’t answer every email, I can at least address some of them in the blog. Supplements are often marketed using unsupported health claims to which is appended the Quack...
Science by press release
Last week I wrote about a study that purported to show that antidepressants have no effect in mild to moderate depression. A careful reading of the paper shows that the authors dramatically overstated their findings, particularly in their public statements to the media. The study has another implication beyond the misleading claims about antidepressants. It is an object lesson in an ongoing...
