Diabetes Mellitus: Overview and Type I Subtype

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes: Management and Pharmacotherapy

Diabetes: Management and Pharmacotherapy

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...

Diabetes Mellitus: Introduction

Diabetes Mellitus: Introduction

Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...

Type II Diabetes I: Introduction

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Type I Diabetes I: Introduction

Type I Diabetes I: Introduction

Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...

Fuzzy Logic Systems

Background:

Classical ontologies struggle with imprecise medical knowledge.
Fuzzy ontologies offer a solution for handling uncertainty in data and knowledge.
Decision support systems are increasingly used for diagnosing conditions like diabetes.

Purpose of the Study:

To develop a novel fuzzy expert system for diabetes decision support.
To introduce a five-layer fuzzy ontology for representing uncertain medical knowledge.
To create a semantic decision support agent for diabetes diagnosis.

Main Methods:

Developed a five-layer fuzzy ontology (knowledge, group relation, group domain, personal relation, personal domain).
Applied the fuzzy ontology to the diabetes domain, creating a Fuzzy Diabetes Ontology (FDO).
Designed a Semantic Decision Support Agent (SDSA) with knowledge construction, ontology generation, and decision-making mechanisms.

Main Results:

The fuzzy expert system effectively models uncertain diabetes knowledge using the FDO.
The SDSA successfully constructs fuzzy concepts, generates instances, and simulates medical staff decision-making.
The proposed system demonstrates effectiveness in diabetes decision support applications.

Conclusions:

The novel fuzzy expert system with a five-layer fuzzy ontology provides effective diabetes decision support.
Fuzzy ontologies are crucial for handling uncertainty in medical decision-making.
The developed SDSA enhances the capability of AI in medical diagnosis.
