概括
2型糖尿病患者的糖尿病神经病变 (DN) 与较低的骨矿物质密度 (BMD) 和较高的跌倒风险有关. 胰岛素耐药性也导致这些人的骨质较差.
科学领域:
- 内分泌学和新陈代谢学
- 骨科和骨健康 骨科和骨健康
- 神经学 神经学
背景情况:
- 糖尿病神经病变 (DN) 是脆弱性骨折的已知风险因素,但连接DN,骨健康和跌倒风险的潜在机制尚未完全理解.
- 2型糖尿病 (T2D) 影响骨代谢,增加骨折风险,神经病变可能会加剧这些影响.
研究的目的:
- 调查T2D和轻度至中度DN的年轻老年患者的骨健康和跌倒风险.
- 为了确定导致骨健康受损和增加在这一群体中跌倒风险的因素.
主要方法:
- 评估了144名没有严重DNA或先前骨折的T2D患者.
- 使用DXA扫描测量了骨矿物质密度 (BMD) 和脊椎骨分数 (TBS).
- 收集了胰岛素耐药性标志物 (例如,TG/HDL比率,TyG指数) 和4年的潜在跌倒数据.
主要成果:
- DN与更高的BMI,禁食葡萄糖,甘油三,TG/HDL比率和TyG指数有关.
- 患有DN的受试者表现出明显的下部部和全骨 BMD,即使在调整后.
- 椎骨分数 (TBS) 与胰岛素抵抗标志物和内脏脂肪组织负相关;在基线时疼痛性神经病变预测了4年后更高的跌倒率.
结论:
- 糖尿病神经病变与骨矿物质密度降低和T2D患者跌倒风险增加有关.
- 胰岛素抵抗是DN的一个关键因素,也与骨质的下降相关,突出了影响骨完整性和跌倒倾向的复杂相互作用.

Diabetes Mellitus: Type 2 and Gestational
5.0K
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

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

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: Management and Pharmacotherapy
1.1K
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.

Psychoneuroimmunology: Diabetes and Cancer

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: Symptoms, Diagnosis, and Complications

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...
