概括
高血糖波动 (MAGE) 和低血糖 (时间低于范围) 与2型糖尿病患者的白质强度过高有关. 低血糖症可能会通过增加葡萄糖变异性来加剧白质变化.
科学领域:
- 神经学 神经学
- 内分泌学 在内分泌学.
- 糖尿病学 糖尿病学
背景情况:
- 大脑小血管疾病,由白质过强度 (WMH) 表示,是糖尿病的并发症.
- 在WMH中,血糖游览的作用,特别是血糖游览的平均幅度 (MAGE),尚不清楚.
研究的目的:
- 在2型糖尿病患者中研究MAGE和WMH之间的关联.
- 探索时间低于范围 (TBR<3.9 mmol/L) 和WMH之间的关系.
主要方法:
- 一项对212名2型糖尿病患者 (50-80岁) 的横截面研究,使用MRI和持续血糖监测.
- 通过Fazekas尺度和定量方法评估WMH体积,将患者分为低 (L-WMH) 和高 (H-WMH) 组.
- 对临床,实验室数据,MAGE和TBR<3.9 mmol/L的分析.
主要成果:
- 与L-WMH组相比,在H-WMH组中观察到更高的MAGE水平.
- 低于范围的时间 (<3.9 mmol/L) 是MAGE升高的独立风险因素.
- MAGE和TBR (<3.9 mmol/L) 独立地与增加的WMH负担相关;MAGE部分调解了TBR-WMH关系.
结论:
- 在糖尿病患者中,MAGE和低血糖症与WMH独立相关.
- 低血糖症可能通过增加葡萄糖波动导致WMH进展.
- 这些发现强调了管理葡萄糖变化和低血糖在预防糖尿病中脑小血管疾病方面的重要性.

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...

Diabetes: Symptoms, Diagnosis, and Complications
495
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 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...

Carbohydrate Metabolism
10.7K
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...

Overview of Carbohydrate Metabolism
674
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...
