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...

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...

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...

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 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...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Area of Science:

  • Biomedical Informatics
  • Genomics
  • Machine Learning

Background:

  • Type 2 diabetes (T2D) presents a significant global health burden, complicated by multifactorial influences.
  • Accurate T2D risk assessment is challenging due to complex genetic and non-genetic factors.
  • Machine learning (ML) offers a powerful approach for analyzing complex datasets like RNA sequencing for T2D risk prediction.

Purpose of the Study:

  • To evaluate feature selection and classification methods integrating diverse data types for predicting weight loss.
  • To enhance the accuracy of predictive models for T2D prevention through weight loss prediction.

Main Methods:

  • Utilized data from 56 participants in a Diabetes Prevention Program study, including clinical, dietary, and transcriptomic data.
  • Applied various feature selection techniques to identify relevant transcripts for classification models.
  • Compared performance of classification models (SVM, logistic regression, decision trees, random forest, extra-trees) with additive data type inclusion.

Main Results:

  • Waist and hip circumference differed significantly between weight loss responders and non-responders (P=.02 and P=.04).
  • Integrating dietary and step count data did not enhance model performance over demographic and clinical data alone.
  • Optimal transcript subsets identified via feature selection improved prediction accuracy; DESeq2 and extra-trees classifier demonstrated superior performance.

Conclusions:

  • Transcriptomic data inclusion shows potential for improving weight loss prediction models for T2D prevention.
  • Identifying individuals likely to respond to weight loss interventions can aid in preventing T2D.
  • Five key genes (CDIPT, MRC2, PATL2, RFXANK, SUMO3) were identified as optimal predictors, with CDIPT, MRC2, and SUMO3 previously linked to T2D or obesity.
