Meal Simulation Model of the Glucose-Insulin System

Dalla Man, Chiara, Rizza, Robert A., Cobelli, Claudio·2007·IEEE Transactions on Biomedical Engineering

Abstract

A simulation model of the glucose-insulin system in the postprandial state can be useful in several circumstances, including testing of glucose sensors, insulin infusion algorithms and decision support systems for diabetes. Here, we present a new simulation model in normal humans that describes the physiological events that occur after a meal, by employing the quantitative knowledge that has become available in recent years. Model parameters were set to fit the mean data of a large normal subject database that underwent a triple tracer meal protocol which provided quasi-model-independent estimates of major glucose and insulin fluxes, e.g., meal rate of appearance, endogenous glucose production, utilization of glucose, insulin secretion. By decomposing the system into subsystems, we have developed parametric models of each subsystem by using a forcing function strategy. Model results are shown in describing both a single meal and normal daily life (breakfast, lunch, dinner) in normal. The same strategy is also applied on a smaller database for extending the model to type 2 diabetes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Hovorka model and the UVAPadova model were originally formulated to represent the physiological behaviour of T1DM individuals, and no modification is necessary for the purpose of the present work.

    “On the contrary, the Hovorka model and the UVAPadova model were originally formulated to represent the physiological behaviour of T1DM individuals, and no modification is necessary for the purpose of the present work.”
  • The first simulation environment circa 2007 was based on the previously introduced Meal Model of glucose-insulin dynamics.

    “The first simulation environment circa 2007 was based on the previously introduced Meal Model of glucose-insulin dynamics 47”
  • By 2006, the minimal model technology had evolved into elaborate quantitative understanding of the human metabolic system, allowing comprehensive description into large, nonlinear models of high order with a large number of parameters.

    “Fast forward to 2006, the minimal model technology has evolved into elaborate quantitative understanding of the human metabolic system, which allowed its comprehensive description, fully implementing the body of knowledge about metabolic regulation into large, nonlinear models of high order, with a large number of parameters.47”
  • Historically, only the pharmacodynamics of glucagon have been included in comprehensive metabolism models.

    “Historically, only the pharmacodynamics of glucagon have been included in comprehensive metabolism models, such as Sorensen's model,11 revisions of the Sorensen model,12,13 and, more recently, the Padova meal model.14”
  • The Hovorka model and the UVAPadova Simulator describe only the glucose metabolism of a subject with type 1 diabetes.

    “While the Hovorka model and the UVAPadova Simulator only describe the glucose metabolism of a subject with type 1 diabetes, the Sorensen model was formulated to simulate the behaviour of both normal and diabetic individuals.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
