Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.6K
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...

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

323
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 Diabetes

1.1K
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

11.3K
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...

Clinical Trials01:16

Clinical Trials

6.9K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Area of Science:

  • Health Informatics
  • Behavioral Medicine
  • Endocrinology

Background:

  • Type 2 diabetes mellitus (T2DM) self-management is crucial, yet education programs face access and adherence barriers.
  • Virtual diabetes self-management education and support are increasingly utilized.
  • The Diabetes Learning in a Virtual Environment (LIVE) study addresses these challenges.

Purpose of the Study:

  • To compare the effects of the LIVE virtual intervention against a control website on diet and physical activity in adults with T2DM.
  • To evaluate behavioral and metabolic outcomes over a 12-month period.
  • To assess the efficacy of immersive virtual environments for diabetes self-management.

Main Methods:

  • A 52-week multisite randomized controlled trial involving 211 adults with T2DM.
  • Participants were randomized to either the LIVE virtual environment or a control website.
  • Data collected via surveys, clinical measures, lab tests, and Fitbit at baseline and 3, 6, 12 months.

Main Results:

  • The LIVE group showed significantly greater weight loss compared to the control group (P=.04).
  • Both groups demonstrated increased physical activity and decreased HbA1c, blood pressure, cholesterol, and triglycerides.
  • Clinically relevant metabolic improvements were observed in participants with baseline HbA1c >8.6% in both groups.

Conclusions:

  • Both virtual and website-based interventions yielded minor positive changes in glycemic control over 12 months.
  • Significant metabolic improvements occurred in participants with higher baseline HbA1c levels, regardless of intervention type.
  • A comprehensive toolkit with diverse services is recommended for future T2DM self-care improvement.
