So, dexamethasone strikes again! I went to the hospital this past Thursday for my monthly infusion of the monoclonal antibody, Daratumumab. Along with the Dara, I get a number of other chemo meds among them dexamethasone. I only get fifteen milligrams of dex these days once a month and that’s probably a good thing because any steroid can be trouble in the long run. Of course my long run is getting palpably shorter, or to put it another way, dex can’t really hurt me in the long run if I don’t have much of a long run. What I can say, though, is that no matter how long my long run is, I’ll make the best of it. I’ve decided that that’s my goal. I’m thinking of my life now as a one mile marathon race. Getting closer to the finish line is no reason to slow up. In fact, it’s all the more reason to step up the effort. Of course, the closer to the finish line we get, the more tired we get so it’s a trade-off. Still, pushing to the end is my goal. But I digress.
What is interesting about dex is it’s effect on my tooth-ache. I mentioned before that I had a nasty tooth-ache that a dex shot in my neck attenuated rapidly and almost eliminated entirely. Well, that tooth-ache has persisted in a low rumble since it returned after a few days following my neck shot. Again, the dex that I took orally on Thursday killed the pain in my tooth right dead. It’s back now because as I’ve become well aware, the relief from dex is very short lived. Oh, I appreciate the pain relief whichever way I can get it, but dex has other side effects that aren’t as welcome as the pain relief. Check out this list of side effects. I’ve experienced many of them over the past couple of years.
[As an aside, I’m writing this sitting in my new La-Z-Boy recliner (thanks to my very generous daughters) in my cozy, warm living room. Carolyn, my love of forty-eight years, while I sit warm and cozy in the living room, is out there walking on the trails in Cumberland in rain as thick as soup. She is accompanied by Tilly, our Bernese Mountain Dog/German Shepherd mix who loves her mom and also most other living things, and swimming too. I hope she gets home soon so we can have a cup of tea together. She did!]
So, what about pig kidneys? Well, lots. This article explains what the experiment was all about. And it was an experiment, of course. Serious ethical issues aside, the experiment was a success. Researchers in New York attached a kidney from a specially raised pig, one that was genetically modified to not produce a certain sugar that caused immediate rejection in humans, to a cadaver. Yes, a cadaver. The objective was to see whether or not the pig kidney could reproduce the function of a normal human kidney, and apparently it did, and splendidly so. The cadaver was special too, of course. I suggest you read the article to get the story from a reputable source.
What’s the big deal, I ask? Researchers genetically modify pigs so that we humans can use their organs. How does that make you feel? The truth is that pig heart valves have been successfully implanted in humans for some time now and researchers have been experimenting with xenotransplantation since the 17th Century. We eat pigs all the time. They are one of our major sources of food. They are also intelligent, rivalling some humans I surmise.
The reason pigs are such a good fit for xenotransplantation is that they are so closely related to us genetically. In fact, we are related to all other living things, animal and plant but with varying degrees of fit in terms of the quantity of genes that we share with them. We are very closely related to chimpanzees sharing something like 99% of DNA with them. (I think that the reason we don’t raise chimps to eat is that they look too much like us.) We share DNA with ducks and cedar trees, snails, and puppy dogs.
From what I can gather from casual observation, we tend to think of all species as distinct from each other and, of course, that’s partially true. Sadly, we are generally ignorant of our place in the scheme of life on this planet. We have been convinced over millennia that we are special under the sun and that all life on the planet is there to serve us. That attitude will ultimately lead to our demise as we Bolsonaro the Amazon rain forest, empty the seas of fish and other life, and generally bulldoze our way through all life on the planet. We take up more and more of the biosphere every year. We, as a species, have no respect for life and from what I can see, have very few mechanisms that would allow us to gain respect for life. Our culture is designed to deny death and thus to ignore life.
Our political systems are geared to produce maximal growth and compete in absurd ways for greater and greater shares of planetary resources. It’s disconcerting to see China and the US embroiled in a chest-thumping match over Taiwan. How stupid. How short-sighted. How ignorant. What are they going to do, lob nuclear weapons at each other? It’s especially ridiculous knowing how closely tied manufacturing in the US is tied to production in China. It’s hard to see how Americans destroying American production in China will help anyone, anywhere. I suspect that the Chinese leadership is in need of a diversion to keep its population’s collective mind off of serious domestic problems. Focussing attention outward is a tried and true method of avoiding domestic conflict.
I could argue that the way we are increasingly economically interdependent through production of commodities in networks that span the globe is encouraging as a basis for concerted action. However, I’m not sure that we have the time to wait for economic interdependence to lead to political interdependence. Finally, I’m not convinced that as a species we are capable of doing what needs to be done to enable us to live in harmony with the rest of life on the planet. It may be that cockroaches will inherit the earth and if that’s the case, so be it.
