My best friend was diagnosed with gout recently. I told him to stop ingesting fructose immediately.
Only twenty five years ago, when I was in training, gout looked like it was like a disease on its way to extinction, sort of like tuberculosis. We were taught it used to be common hundreds of years ago but that it was pretty rare. Sure, I had a few patients with gout in my clinic with gout but I would see a case once every couple of months at most.
Now, it’s exploded in frequency.
Gout is very, very bad. Not only because it is excruciatingly painful. (In some patients, you can’t even let a gouty big toe brush against tissue paper without unbearable pain. It’s one of the few things that may rival childbirth in the intensity of pain.) And not only because it is a major risk factor for heart disease. Not only because it causes heart disease. No, it’s very bad because your risk of dying goes up by 25% if you have gout. Continue reading “Gout and Cardiovascular Disease”
The bacteria called Fusobacterium nucleatum plays an important role in causing gingivitis and periodontal disease. It is also found in the placenta. Gingivitis is an interesting disease, because people who have gingivitis also tend to have higher risk of a number of other problems, such as diabetes and heart disease. It has been a long-running debate whether gingivitis causes these other diseases or whether it’s just a non-causal correlation.
Into that debate drops this bombshell: a paper recently published in Nature just reported that Fusobacterium, which was previously reported to be found in many patients with colon cancer and to induce tumors (in this paper, they show the bacteria recruit immune cells to the tumor, which is very very bad Continue reading “Colon Cancer and Bacteria”
Ed Thorpe is the mathematician who wrote “Beat the Dealer.” In that book, he detailed his invention of card counting. He proved for the first time that it was possible to beat the Las Vegas casinos in blackjack, something that was believed to be impossible. He also invented the Black-Scholes equation several years before Black and Scholes (and in fact Black and Scholes directed credited Thorpe’s writing for inspiring them), which resulted in a Nobel Prize. Except he didn’t share in the Prize because he used the equation to make millions of dollars on Wall Street rather than publishing it. But that’s another story.
Thorpe writes about the time he was asked to dinner with Warren Buffett. Ralph Gerard, the dean of UC Irvine, where Ed was a professor of mathematics, was thinking about moving his money from Buffett to Ed. Warren was secretly assessing Ed’s bona fides.
Ed passed muster when he correctly answered Warren’s question about the oddly numbered dice. This is a curious phenomenon. Let’s say you have three dice. The first die A is numbered 3,3,3,3,3,3. The second die is numbered 6,5,2,2,2,2. The third die C is numbered 4,4,4,4,1,1.
If you roll the dice, then most of the time, die A will beat B, B will beat C, and… C will beat A. Continue reading “Metas, Or, Biology is Non-Transitive”
There is a fantastic post by luysii on his Chemiotics II blog. In it, he discusses his theory that senescent cell may be producing mediators that cause chronic fatigue syndrome (CFS). I think it’s a fascinating idea.
CFS is a terrible disease, made worse by the fact that some physicians don’t believe that it exists. Trust me, it does.
An interesting things about the disease is that it tend to occur in high income countries, and almost never in developing countries, and that in my experience, it tends to occur in women from mid to higher socioeconomic strata. This is in contrast to fibromyalgia, which Continue reading “Being Sleepy and Tired”
FDA, in 2008, did something that many people thought was preposterous. They began requiring companies to prove that diabetes drugs they developed did not kill people. Actually, to be more specific, they required the companies to prove that the risk of dying on the drug was not more than 1.8X higher than not being on the drug.
This caused an uproar. To prove such a ridiculous thing, some companies howled, would Continue reading “Will We Cure Diabetes, Heart Disease, and Alzheimer’s Disease One Day?”
Mites scare me.
When I was an undergrad, working on fruit flies (I would sit in a coldroom, which was essentially a big refrigerator, injecting fruit fly eggs with a tiny glass needle I blew myself, making some of the very early transgenic fruit flies), mite infestations would occasionally sweep through the lab, killing hundreds of thousands of fruit flies. Some of the flies represented years of work by students and postdocs.
Which brings us to rosacea. Continue reading “Rosacea and Tiny Mites”
Museum of Natural History. That’s a funny name, isn’t it? The whole building is full of scientific and biological items like skeletons and fossils. Where’s the history part? Shouldn’t it be called Museum of Science? Most people would put science and history on the opposite end of the spectrum.
When you hear a name like that, it almost feels like someone’s trying to obfuscate, trying to Continue reading “It’s a Shame that Scientists Develop Drugs, Instead of Engineers”
