I’m going to split blog postings into COVID-19 sections and H5N1 sections for now. I might someday split them into separate postings. Psychology Many years ago, I heard this George Carlin joke: “Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?” It… Continue reading 2024-05-04 General

Pathology Why do kids and old people have such different reactions to COVID-19? This paper from UK (2024-04-15) says that kid and adult epithelial cells (which line mucous membranes) are different. In particular, cells in elderly people had more of the receptors which SARS-CoV-2 uses to get into the cells, and kids’ cells generated more… Continue reading 2024-04-19 General

Long COVID This paper from Sweden (2024-04-04) found that patients with Long COVID didn’t have a worse time after exercise than controls. This is, on its face, a surprising finding because other studies (like this one) have definitely found that post-exertional malaise (PEM) (i.e. crashing after exertion) is a real thing. I have two observations:… Continue reading 2024-04-05 General

Treatments This article from USA (2024-03-25) says that the FDA has approved Pemgarda, a monocolonal antibody, for use as a pre-exposure preventative for immunocompromised people. It will be used sort of like a vaccine. (Evusheld used to be effective for that, but SARS-CoV-2 mutated enough that Evusheld stopped being effective.) This is big news for… Continue reading 2024-03-29 General

Long COVID Today is International Long COVID Awareness Day. Yeah, I wouldn’t have known either if I didn’t actively seek out COVID-19 information. It got almost no media coverage. Ironically, the thing that did get media coverage today was a presentation which found that Long COVID wasn’t all that different from what people got after… Continue reading 2024-03-15 General

Long COVID This paper from UK (2024-03-01) found that the blood of people who just had a COVID-19 infection was measurably different between those that developed/did not develop Long COVID later. Specifically, the ones who later developed Long COVID showed lower levels of blood iron and more inflammation. It’s not that they weren’t eating enough… Continue reading 2024-03-08 General

Pathology This paper from USA (2024-02-07) found that vapes with propylene glycol and vegetable glycerin — with or without nicotine — increased the risk of COVID-19. However, vapes with benzoic acid added didn’t give any higher risk than not vaping. This preprint from China (2024-02-23) found SARS-CoV-2 virus in fluid in the middle ear. (Fluid… Continue reading 2024-03-01 General
