Summary
Research on type 2 diabetes mellitus (T2DM) shows a significant increase in publications from 1951-2012. Bibliometric analysis reveals the United States as the leading contributor to T2DM research output.
Area of Science:
- Endocrinology and Metabolism
- Public Health
- Bibliometrics
Background:
- Type 2 diabetes mellitus (T2DM) represents a growing global health challenge.
- Understanding research trends is crucial for strategic development and funding in T2DM research.
Observation:
- A comprehensive bibliometric analysis of T2DM research was conducted using data from 1951-2012.
- Data were extracted from the Science Citation Index Expanded, focusing on English-language publications and excluding Type 1 and gestational diabetes.
Findings:
- A total of 24,783 T2DM research items were published, receiving 476,002 citations.
- Publication output peaked in 2010, with the United States (28.8%), United Kingdom (8.2%), and Japan (7.7%) as leading contributors.
- Harvard University and the University of California were top institutions, while 'Diabetes,' 'Diabetologia,' and 'Diabetes Care' were leading journals.
Implications:
- The rising volume of T2DM research mirrors the increasing global disease burden.
- Bibliometric analysis offers valuable insights for scientists and funding bodies to guide future research strategies in T2DM.
- International collaboration, particularly between the US and UK, is a significant aspect of T2DM research.

5.6K
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...

15.1K
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...

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...

4.5K
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,...

01:15Diabetes: Management and Pharmacotherapy
1.5K
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.

01:27Glucose Transporters
28.4K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
