- 医疗成像医学成像
背景情况:
- 2型糖尿病 (T2DM) 是一个日益严重的全球健康问题.
- 血糖控制,特别是每次访问的葡萄糖变化 (GV),越来越被认为是糖尿病并发症的关键因素.
- 在T2DM患者中,GV对大脑健康的影响仍然不完全理解.
研究的目的:
- 检查T2DM患者中访问到访GV和大脑形态学之间的关系.
- 评估GV与T2DM患者认知表现之间的关联.

主要方法:
- 一个回顾性队列研究,涉及173名T2DM患者和253名健康对照.
- 所有参与者都进行了认知评估和结构性MRI.
- 在T2DM患者中使用HbA1c标准偏差计算访问到访问的GV;采用多重线性回归分析.
主要成果:
- 高GV与全球认知表现和执行功能下降相关.

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
487
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: 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 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,...
