概括
持续血糖监测 (CGM) 指标,包括时间范围和血糖变化,与2型糖尿病中的角膜神经病变有关. 这些发现突出了CGM.
科学领域:
- 眼科医生 眼科 眼科
- 内分泌学 在内分泌学.
- 糖尿病学 糖尿病学
背景情况:
- 角质神经病是糖尿病的并发症,但其与持续血糖监测 (CGM) 度量表的关系尚不清楚.
- 在体内共聚焦显微镜 (IVCM) 允许对角膜神经结构和细胞变化的详细评估.
研究的目的:
- 调查IVCM评估的角膜神经病变与2型糖尿病患者的各种CGM衍生的血糖指标之间的关联.
主要方法:
- 一项涉及277名2型糖尿病患者的横截面研究,他们接受了为期14天的失明CGM和角膜IVCM.
- 用通用估计方程模型来分析HbA1c和CGM指标 (例如,范围内的时间,范围以上的时间,葡萄糖变化) 与角膜神经纤维和细胞指标的关联.

Diabetes Mellitus: Type 2 and Gestational
4.9K
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
5.3K
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...

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Ending Relationships
186
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Glucose Homeostasis: Regulation of Blood Glucose
4.1K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Pathophysiology of Diabetes
3.5K
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,...
