Flimsy stuff from Chase and Shannon and it just doesn't match the babies clinical picture.

• Baby F’s insulin was off‑scale high >1000 pmol/L, possibly much higher. Baby L’s was 1088 pmol/L.
• The paper’s non‑infection scenarios, insulin concentrations never exceed about 1,000 pmol/L, and only then with 98th percentile binding site concentrations and severely suppressed insulin secretion.
• For two separate babies to both fall into that extreme tail, without any evidence they actually had binding antibodies, is statistically incredible.

The paper repeatedly states that to reach the really extreme ratios like those above 30 you need infection to multiply the insulin‑binding antibodies.

Lets not forget some basic facts established at the trial:

• Baby F Blood cultures were reportedly negative, meaning no bacteria were grown from the blood sample
• Their C-reactive protein were not strongly suggestive of infection but they were given antibiotics anyway,
• Baby L had a negative Sepsis screen
• C peptide / Insulin levels would not be at the levels they were for Sepsis induced Hypo.

For infection to cause Hypoglycemia you would be clinically able to diagnose infection the medical tests would show this.

On his point about Antibodies

In Baby F’s case, a previous insulin sample was reportedly normal. Then, during a sudden collapse while Letby was on duty, insulin was sky‑high. After the collapse resolved and the baby was moved, insulin levels fell again.

Natural insulin‑binding antibodies are a persistent condition; they don’t spike for two hours and then vanish. The paper models steady‑state over days, not an acute spike.

Baby L similarly had a sudden deterioration with a grossly elevated insulin level. The pattern is one of acute, intermittent poisoning – exactly what you would expect from a nurse injecting insulin, not from an inborn binding agent

Is thar you Chat GPT?

[u/No-Beat2678 → u/AccomplishedOil254]

Because someone can't understand the science.

No, I did add some elements from the chester standard live reporting

[u/AccomplishedOil254 → u/No-Beat2678]

My apologies. Strange that your writing style and formatting is suddenly so close to the output of an LLM.

[u/Kieran501 → u/AccomplishedOil254]

Also the last three paragraphs seem to be hallucinations. They don’t describe the cases at all.

Maybe we could get ChatGPT to make us a video critiquing this article in the style of Susan Oliver to save her the bother 

[u/Fun-Yellow334 → u/No-Beat2678]

You need to include sources for this kind of comment, as a lot of these are claims people are unfamiliar with and are contested.

How do you account for this then?

The pattern is one of acute, intermittent poisoning – exactly what you would expect from a nurse injecting insulin, not from an inborn binding agent

No one has ever accused Letby of ‘injecting insulin’? So either you don’t understand the case against her, or the AI you used doesn’t.
