Monoclonal Antibodies are Back

At last, the state of Indiana put out a useful tweet:

People with weakened immune systems are at greater risk if diagnosed with #COVID19, but there are treatments that can help prevent serious illness. Learn more at http://tinyurl.com/C19treatment

The link goes to the state's page on COVID treatment, which includes the monoclonal antibody Sotrovimab. It's available, has emergency use authorization and effective against Omicron.

The clinical trial participants were at high risk of COVID progression due to age, obesity, diabetes and other risk factors. This was a phase 3, multicenter, randomized, double-blind, placebo-controlled trial.

From the study:

In this prespecified interim analysis, which included an intention-to-treat population of 583 patients (291 in the sotrovimab group and 292 in the placebo group), 3 patients (1%) in the sotrovimab group, as compared with 21 patients (7%) in the placebo group, had disease progression leading to hospitalization or death (relative risk reduction, 85%; 97.24% confidence interval, 44 to 96; P=0.002). In the placebo group, 5 patients were admitted to the intensive care unit, including 1 who died by day 29. Safety was assessed in 868 patients (430 in the sotrovimab group and 438 in the placebo group). Adverse events were reported by 17% of the patients in the sotrovimab group and 19% of those in the placebo group; serious adverse events were less common with sotrovimab than with placebo (in 2% and 6% of the patients, respectively).

Evusheld (tixagevimab and cilgavimab) is also available as prophylaxis for moderately to severely immunocompromised people.

Fasting blood sugar & insulin have crept up!

It's pretty bad when even conventional medicine thinks your blood sugar is high. I had lab tests done last week, as I do every year, and saw things were going in the wrong direction. Photo from Pixabay . Uh-oh. Ideal blood sugar is about 70-90. Your blood sugar can be high because you're stressed or ill, but I felt OK. I can't blame it on cortisol, which was smack in the middle of the normal range. And my A1c, which reflects blood sugar over the past few months, shows that whatever is going on has been happening for a while. My insulin is more than double what it should be. Oddly, my triglycerides, which typically indicate carb consumption, were good. I don't have an explanation for the triglycerides. I should have suspected something was wrong, though. I've felt very tired and a little sad for the past few months. Unlike many people with higher than ideal blood sugar and insulin, I had only gained about three pounds. Regardless of my good weight and triglyceride...

Infrared Light: How much is too much?

It's the sort of thing that sounds like quackery: a pad with tiny red LED lights and a few buttons that's supposed to help you heal, just $30 on ebay. I never would have bought it, but Dr. Davis gave a presentation on infrared light late in 2024. Since I was still suffering from achilles tendonitis after being floxxed , I decided to try it. I wrapped it around my ankle and turned it on the lowest setting for five minutes. Nothing seemed to happen, but the next day, I wrote, My tendonitis is GONE after one 5-minute treatment! I didn’t feel it doing anything, I didn’t think it was going to do anything (at least not that quickly), but for the first time in several months, I’ve gotten out of bed and started walking normally and didn’t have any pain reaching with my left arm. I'd been shuffling around like an 80-year-old woman after getting out of bed in the morning. The tendonitis returned, but it was improved. I eventually had physical therapy for it, and now, apart from a l...

Lousy Mood? It Could be the Food

Here's a funny AMV(1) on what it's like to be depressed, apathetic and overly sensitive. Note: explicit (but funny) lyrics in the video. Hearing this song brought a startling realization: I used to be emo, but with normal clothes. Sulking, sobbing and writing poetry were my hobbies. When I was a kid, my mother said that she wouldn't know what to do to punish me if I had done something wrong. And yet things got worse. Over a two-week period in 1996, my best friend moved away, I lost my job and broke up with my boyfriend. I lost my appetite and lived on a daily bagel, cream cheese and a Coke for the next few months. I had tried counseling, and didn't find it helpful; in fact, I found reviving painful memories was pointless. Not thinking about them, on the other hand, worked wonders. Later on, so did studying philosophy and learning to think through emotions instead of just riding through them. But what's blown away all the techniques is diet. Since I s...

Avoiding a Nightmare by Using Math

The answer lies in trigonometry. -Sherlock Holmes Don't worry if you never learned trigonometry--the answers here lie in arithmetic. Medical test results often come back positive or negative, as if the result were a certainty. Of course, there is the accuracy, but if the accuracy is 99% or so, what does that really mean? That you should get your affairs in order? Before you call your probate attorney, let's take an example from the book Calculated Risks by Gerd Gigerenzer. Let's say you're a 40-something year old woman with no symptoms of breast cancer. You have a positive mammogram. What are the odds you have breast cancer? Using some assumptions about test accuracy and rates of disease based on real data, the odds that you'd have breast cancer are one in eleven according to Gigerenzer. (If you were way off, don't feel bad--most of the physicians Gigerenzer tested were way off, too--and they had the data in front of them. Not that that's comforting in every...
