概括
代谢灵活性,身体的燃料切换能力,与瘦人相比,超重/肥胖和2型糖尿病 (T2D) 个体减少. 这表明体重状况,而不是T2D本身,是代谢不灵活的主要驱动因素.
科学领域:
- 代谢生理学 代谢生理学
- 内分泌学 在内分泌学.
- 人类的新陈代谢.
背景情况:
- 2型糖尿病 (T2D) 的特点是胰岛素耐药性和潜在的代谢灵活性受损.
- 代谢灵活性是指身体在代谢碳水化合物和脂肪之间有效切换能量的能力.
- 代谢灵活性受损可能会导致T2D的病理生理学.
研究的目的:
- 系统地审查和对瘦身,超重/肥胖和T2D群体的代谢灵活性进行元分析.
- 评估这些群体之间的代谢灵活性,以呼吸交换比率 (ΔRER) 在高胰岛素-高血糖合剂期间的变化来衡量,如何不同.
- 研究身体质量指数 (BMI) 和其他因素对代谢灵活性的影响.
主要方法:
- 我们对PubMed进行了全面的文献搜索,以确定相关的研究.
- 包括65项研究,其中35项使用标准化胰岛素输注速率进行比较分析.
- 从985名参与者 (256名瘦身者,497名超重/肥胖者,232名T2D) 的数据进行了元分析.
主要成果:
- 与超重/肥胖 (0.07) 和T2D (0.07) 组相比,胰岛素刺激的ΔRER在瘦个体 (0.10) 中显著更高,这表明瘦个体的代谢灵活性更大.
- 在小组内观察到很高的统计异质性,这表明 ΔRER 测量有显著的变化.
- 超回归分析显示,只有BMI与ΔRER有显著的关联,其他因素有助于异质性.
结论:
- 与瘦个体相比,超重/肥胖和2型糖尿病患者的代谢灵活性降低.
- 超重状态似乎比2型糖尿病本身更重要地决定了代谢灵活性.
- 这些发现挑战了2型糖尿病特有的独特代谢不灵活度值的概念,并强调了代谢研究中标准化数据报告的必要性.

Carbohydrate Metabolism
10.5K
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
2.3K
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 Mellitus: Type 2 and Gestational
2.1K
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...

Pathophysiology of Diabetes
805
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
471
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
204
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.
