A different camphorweed stage

with 36 comments

In yesterday’s post you saw that the ray florets in a camphorweed (Heterotheca subaxillaris) flower head sometimes curl like little ribbons. Now the same stand of plants in the northeast quadrant of Mopac and US 183 on August 22nd lets you see the remains of a camphorweed seed head. The bright and pretty yellow in the background came from some “common” sunflowers (Helianthus annuus).

Yesterday’s post also dealt with the early and continuing politicization of the Covid-19 pandemic. On July 3rd I mentioned that some countries were using the drug ivermectin as a therapeutic in treating Covid-19, while at the same time some authorities continued saying the drug is ineffective for that purpose. Regardless of the truth of ivermectin’s effectiveness, which of course as a layman I was (and still am) in no position to know, I lamented the fact that large online sites like Facebook and Twitter were banning people, some of them highly qualified, from even discussing the matter. That’s not in the tradition of a country that thinks so highly of free speech that it’s mentioned in our Constitution’s Bill of Rights.

Since my July 3rd post there have been new developments about ivermectin. Before I go into them, let me tell you what ivermectin is. “In 2015, the Nobel Committee for Physiology or Medicine, in its only award for treatments of infectious diseases since six decades prior, honoured the discovery of ivermectin (IVM)…. IVM as deployed worldwide since 1987 has made major inroads against two devastating tropical diseases, onchocerciasis and lymphatic filariasis.” It’s also the case that “Ivermectin is FDA-approved for use in animals for prevention of heartworm disease in some small animal species, and for treatment of certain internal and external parasites in various animal species.”

Now for the recent developments.

A rural Oklahoma doctor said patients who are taking the horse de-wormer medication, ivermectin, to fight COVID-19 are causing emergency room and ambulance back ups.

“There’s a reason you have to have a doctor to get a prescription for this stuff, because it can be dangerous,” said Dr. Jason McElyea.

Dr. McElyea said patients are packing his eastern and southeastern Oklahoma hospitals after taking ivermectin doses meant for a full-sized horse, because they believed false claims the horse de-wormer could fight COVID-19.

“The ERs are so backed up that gunshot victims were having hard times getting to facilities where they can get definitive care and be treated,” he said.

That’s something McElyea said is now backing up ambulance systems as well.

“All of their ambulances are stuck at the hospital waiting for a bed to open so they can take the patient in and they don’t have any, that’s it,” said Dr. McElyea. “If there’s no ambulance to take the call, there’s no ambulance to come to the call.”

Rolling Stone Magazine picked up the story, as did MSNBC and various other outlets. Some of them put a decidedly “look at those stupid hicks swallowing horse paste” spin on their telling of it, conveniently failing to even mention that ivermectin does have approved human uses and that some other countries have been administering it for Covid-19.

One little problem: the story was untrue. An MSN article details the things that were wrong with it.

  • Here’s the second development. In August, a doctor who favors the use of ivermectin in treating Covid-19 wrote a remote prescription for a patient in an Ohio hospital’s intensive care unit. After the hospital refused to administer the drug because it’s not approved for that purpose in the United States, the patient’s family went to court. On August 23rd a judge ordered the hospital to administer the prescribed ivermectin. Then on September 6th another judge reversed the first judge’s order, siding with the hospital’s stance that government agencies in the United States haven’t approved ivermectin for Covid-19. The second judge noted that “This Court is not determining if ivermectin will ever be effective and useful as a treatment for COVID-19.”
  • In the third and most important development, the September 2021 issue of the medical journal New Microbes and New Infections reports the following:

Since March 2020, when IVM (ivermectin) was first used against a new global scourge, COVID-19, more than 20 randomized clinical trials (RCTs) have tracked such inpatient and outpatient treatments. Six of seven meta-analyses of IVM treatment RCTs reporting in 2021 found notable reductions in COVID-19 fatalities, with a mean 31% relative risk of mortality vs. controls. During mass IVM treatments in Peru, excess deaths fell by a mean of 74% over 30 days in its ten states with the most extensive treatments. Reductions in deaths correlated with the extent of IVM distributions in all 25 states with p < 0.002. Sharp reductions in morbidity using IVM were also observed in two animal models, of SARS-CoV-2 and a related betacoronavirus. The indicated biological mechanism of IVM, competitive binding with SARS-CoV-2 spike protein, is likely non-epitope specific, possibly yielding full efficacy against emerging viral mutant strains.

If you wish, you can read the full article.

So it seems the evidence is now coming down in favor of ivermectin’s effectiveness in treating Covid-19. We’ll see if future research keeps supporting that conclusion. We’ll follow the science.
