Diabetes: Management and Pharmacotherapy

536
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

2.0K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Peripheral Artery Disease I: Introduction

68
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Diabetes Mellitus: Type 2 and Gestational

3.2K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Area of Science:

  • Physiology
  • Biomedical Engineering
  • Computational Biology

Background:

  • Existing diabetes models lack comprehensive glucose dynamics and endogenous insulin representation, particularly for type-2 diabetes.
  • Current models inadequately address exercise impact on blood glucose regulation.
  • A gap exists in physiological models capable of describing insulin-independent diabetic behavior.

Purpose of the Study:

  • To develop a constraint-based, comprehensive physiological model of blood glucose dynamics.
  • To fill the gap in literature regarding models that incorporate exercise and endogenous insulin effects.
  • To create a model applicable to type-2 diabetes, which affects 90% of the diabetic population.

Main Methods:

  • A multi-compartment model with a central 'plasma' compartment containing state variables.
  • Metabolic processes and basal rates are constrained within saturation limits.
  • The hyperbolic tangent function represents the influence of plasma variables on metabolic rates.
  • Model validation using clinical experiments and continuous glucose monitoring data.

Main Results:

  • The model achieved an average correlation coefficient of 0.85 ± 0.13 in fitting experiments.
  • Simulated responses showed strong agreement with target data.
  • The model provides insights into the metabolic effects of plasma variables on glucose metabolism.

Conclusions:

  • A comprehensive glucose regulation model with exercise dynamics for diabetes modeling has been developed.
  • The model, while not considering individual factors like age or gender, is applicable in operational research via mathematical programming.
  • This work advances the physiological modeling of diabetes, particularly type-2.
