Exploring the Insulin Evidence in the Lucy Letby Case

Science on Trial presents videos breaking down the evidence in the Lucy Letby case. Our videos provide a broad overview of the claims made by the prosecution expert witnesses. We identify core issues with the expert claims, and identify potential explanations for the evidence.

Overview of Mortality at Countess of Chester

SoT walks you through the way scientists might view the increased mortality observed in 2015-2016.

Placental Transmission of Infectious Disease

The role of viruses in stillbirths is a well known event, we consider the incidence of viral transmission in stillbirths, and the means by which pathogens can cross the placenta.

The Interplay between Insulin and Glucose

The regulation of blood glucose levels is tightly controlled in older infants. However, preterm neonates often experience issues with glucose homeostasis which can result in a number of abnormal events. We explore the insulin claims in the Lucy Letby case in the context of these known concerns.

Insulin Release during Infection

Sepsis can cause insulin to be released which causes a shift in blood glucose concentration. We discuss potential mechanisms for these changes and consider them in the context of the Lucy Letby case.
