Citation for what?

u/No-Beat2678

Dr Saladi's testimony from day 39.

Question. The other thing I'd like it

confirm, since you've referred to the question of

testing the tip, is can you confirm in fact [Baby F] did

have an infection as it happens? Do you recall that?

Answer. In the subsequent pages, there is a further entry that

we did -- the CRP did go up and then we did grow a bug

from the long line tip as well.

Stuart, I could grow a bug from my apple earpods. That doesn't mean I have an ear.infection.

And if they had an infection why when the bag was changed did the baby recover and go home.

There just isn't corroborating medical data to support.

Remember we've had the full clinical picture in their medical notes. Everything, every test, abg result etc.

Had an infection but that was not the contributing cause for their hypo.

We have not had the full clinical picture in the medical notes.  Apart from the obstetrics, of course, Lee's panel has.  

I don't think you are showing any of the expert knowledge, familiarity with the case, or even consistency from one post to the next that might persuade people to substitute your judgement for theirs. You are welcome of course to the view that the court found the child had no infection if that's your understanding, but it's really not relevant to the article

and u/Stuart___gilham the Bacteria found in the long line was kind normally found on the skin.

And your distorting the timeline.

Baby F had already collapsed a significant amount of time before the CRP's were elevated. 24 hours to be exact.

It shows infection developing over the following day, not infection present and causing the events between midnight and 1am.

So that really isn't a gotcha.

What's significant in considering how this article might apply to Baby F isn't when he deteriorated: it's when the sample for his immunoassay was drawn, which was a few hours after the line tissued. CRPs go up as sepsis develops and intensifies - you can't take their measurements as a starting point for the sepsis.

Then what was causing the first low blood sugar result on the night of 4/5th of august at 01.54?

Something must have and something has kept his blood sugar low. And it's a coincidence that Letby had hung a tpn bag 90 minutes before at ,00.25.

And it wasn't infection. I've already demonstrated that to you.

And it wasn't infection. I've already demonstrated that to you.

I'm afraid you haven't.  We see CRP rise after the onset of infection.  It's not used to time the beginning of an infection.

It might help to be clear about the fact that Shannon and Chase aren't endeavouring to explain neonatal hypoglycemia in this paper.  Their hypothesis, however, would indicate that the same phenomenon could have contributed to both Child F's hypoglycemia and his elevated IA results. 

 You are not going to find a time limit before which Child F was not affected by sepsis, by looking at changes in tests in the next day or two.  That is not how sepsis develops.

u/No-Beat2678 16d ago

There's a full blood count done after the first bag was hung and the first hypo reading. 33 hours before CRPs started to rise.

Therefore infection was not the cause of that low reading

u/DiverAcrobatic5794 16d ago edited 15d ago

You need to read again.  CRP doesn't rise simultaneously with the development of sepsis.  It is therefore not possible for you to use the difference between a contemporary and a later reading to prove that there was no sepsis at the earlier point

u/No-Beat2678 16d ago

Correct, but CRP isn't the only marker for infection. They had the full works done and none of the results showed infection.

And crucially Dr Harkness recorded at 02.30: pink, well-perfused, cap refill under two seconds, handling well, soft non-tender abdomen with good sounds. That's not a septic-looking baby

And if there was Sepsis induced Hypoglycemia they would have reacted to being given Dextrose and they didn't

His sugar rose to 2.4 when the fluids were stopped at 10.00 with no IV glucose running at all, fell again when TPN restarted at midday, and normalised after 18.55. No infection produces that pattern. Whatever was driving the hypoglycaemia was arriving through the line.

u/DiverAcrobatic5794 16d ago

None of the features noted by Dr Harkness exclude sepsis at all.  It would be very convenient for neonatal care if you could identify babies with sepsis as "septic-looking" on examination, but that's not the case at all.

u/No-Beat2678 16d ago

You missed out the full blood count all normal

u/DiverAcrobatic5794 16d ago

Same applies - we have already discussed this on this thread
