概括
2型糖尿病 (T2DM) 与皮质薄化有关,特别是在西班牙裔个体中. 这种关联是由血糖控制不良驱动的,由更高的血红蛋白A1c水平表明.
科学领域:
- 神经科学是一个神经科学.
- 内分泌学 在内分泌学.
- 老年学是一门学科.
背景情况:
- 连接2型糖尿病 (T2DM) 和痴呆症的机制尚不清楚.
- 之前的研究还没有充分探索T2DM对不同,认知健康的老年人大脑结构的影响.
研究的目的:
- 研究T2DM与大脑结构 (皮层厚度,海马体积) 之间的关系.
- 确定T2DM对大脑的影响是否独立于社会经济因素和并发症.
- 探索高血糖和高胰岛素血症的作用,以及这些关联中的种族/民族差异.
主要方法:
- 在2171个认知不受损的老年人中,对大脑结构 (皮层厚度,海马体积) 的分析.
- 对T2DM协会的统计检查,控制社会经济地位和并发症.
- 调查高血糖症 (血红蛋白A1c) 和高胰岛素血症作为驱动因素.
- 结果的分层根据自我报告的种族/种族.
主要成果:
- T2DM与皮质厚度降低相关,独立于混因素.
- 较高的血红蛋白A1c (HbA1c) 水平与糖尿病人和非糖尿病人的皮质较薄有关.
- 根据种族/种族,T2DM与皮层厚度的关联差异很大,在西班牙裔参与者中最为明显.
结论:
- T2DM与皮层稀释有关,主要是由低血糖控制 (HbA1c升高) 驱动的.
- T2DM对皮质厚度的影响在不同种族和族群之间存在差异.

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...

Psychoneuroimmunology: Diabetes and Cancer
19
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

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...

Pathophysiology of Diabetes
818
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
486
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
213
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.
