Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.5K
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...

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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

11.2K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Pathophysiology of Diabetes

956
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,...

Diabetes: Symptoms, Diagnosis, and Complications

557
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Hypertension III: Clinical Manifestations and Diagnostic Studies

15
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Area of Science:

  • Endocrinology
  • Network Medicine
  • Public Health

Background:

  • Type 2 diabetes mellitus (T2DM) patients face a high risk of multiple comorbidities.
  • Understanding the complex interplay of these comorbidities in T2DM is limited.
  • Electronic medical records (EMRs) offer a valuable resource for studying multimorbidity patterns.

Purpose of the Study:

  • To investigate prevalent comorbidities in T2DM patients.
  • To analyze the interrelationships between these comorbidities using network analysis.
  • To identify sex- and age-specific multimorbidity patterns in T2DM.

Main Methods:

  • Utilized EMR data from 496,408 Chinese T2DM patients.
  • Constructed global and age/sex-specific multimorbidity networks.
  • Applied network metrics to assess network structure and identify hub, root, and burst diseases.

Main Results:

  • Identified interconnected comorbidities in T2DM, often appearing in clusters.
  • Revealed age-specific outbreaks and sex-specific core diseases.
  • Demonstrated distinct multimorbidity network structures between males and females.

Conclusions:

  • T2DM multimorbidity presents as interconnected clusters and age-specific outbreaks.
  • Timely detection and intervention for core diseases in each sex are crucial.
  • This network analysis provides a data-driven foundation for clinical prevention and therapeutic strategies in T2DM.
