Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.3K
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: Symptoms, Diagnosis, and Complications

522
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...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

919
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,...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

11.0K
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: 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

257
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...

Summary

Hispanic/Latinos showed higher diabetes progression from prediabetes, while Black individuals had lower reversion rates. Social factors influenced Hispanic/Latino progression, highlighting the need for culturally tailored diabetes prevention.

Area of Science:

  • Endocrinology and Metabolism
  • Health Disparities Research
  • Social Determinants of Health

Background:

  • Racial and ethnic minorities experience disproportionately higher rates of diabetes.
  • Social characteristics like family structure, social support, and loneliness may exacerbate these health disparities.
  • Understanding longitudinal changes in glucose metabolism (prediabetes to diabetes or normoglycemia) across diverse populations is crucial.

Purpose of the Study:

  • To evaluate longitudinal rates of progression from prediabetes to diabetes and reversion to normoglycemia in a diverse older adult population.
  • To examine the influence of race/ethnicity and social variables on these glycemic transitions.
  • To identify potential targets for culturally specific interventions to reduce diabetes disparities.

Main Methods:

  • Analysis of the longitudinal Health and Retirement Study (2006-2014) with 2229 individuals and 2625 follow-up intervals.
  • Assessment of 4-year progression and reversion rates using HbA1c levels and physician-diagnosed diabetes status.
  • Application of chi-square and logistic regression models, controlling for comorbidities and demographics, to analyze race/ethnicity and social factors.

Main Results:

  • Overall, reversion from prediabetes to normoglycemia (36%) was more common than progression to diabetes (17%).
  • Hispanic/Latino individuals exhibited higher odds of progression compared to Whites, while Black individuals showed lower odds of reversion.
  • Social variables, particularly family reliance and lower loneliness among Hispanics/Latinos, reduced progression odds, but did not impact Black reversion rates.

Conclusions:

  • Distinct transition pathways and social profiles exist for Hispanic/Latinos and Black individuals regarding diabetes development.
  • Social factors significantly influence diabetes progression in Hispanic/Latinos, but not reversion in Black individuals.
  • Culturally tailored interventions addressing social determinants are essential for mitigating diabetes disparities.
