概括
患有2型糖尿病 (T2DM) 的绝经后妇女的骨髓脂肪表现出改变的组成,特别是在大腿骨头和L3脊椎. 这些发现突出了与T2DM相关的特定BMAT变化.
科学领域:
- 内分泌学 在内分泌学.
- 放射学 放射学是一门学科.
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 骨髓脂肪化 (BMAT) 的变化与2型糖尿病 (T2DM) 的骨不良影响有关.
- 了解良好控制的T2DM中的BMAT特征对于评估骨健康至关重要.
- 绝经后的女性是研究T2DM相关骨变化的关键人口.
研究的目的:
- 在经期绝经后的女性中,有良好的T2DM控制的BMAT的含量和组成的特征.
- 为了研究与没有T2DM的女性之间的BMAT质子密度脂肪分数 (PDFF) 和明显的脂质不和水平 (aLUL) 的差异.
主要方法:
- 一项横截面研究,比较了绝经后女性的T2DM (n=29) 和没有T2DM (n=170).
- 使用水脂肪分离成像 (WFI) 评估腰椎和近腰大腿骨PDFF.
- H-磁共振光谱 (MRS) 用于确定L3脊椎和大腿部的aLUL,并对混因素进行统计调整.
主要成果:
- 患有T2DM的女性比对照群更重,骨矿物质密度 (BMD) 更高.
- 在调整后,T2DM组的基于WFI的股骨头PDFF较低 (88.0%vs90.6%,P<.001).
- 在调整后,L3脊椎aLUL在T2DM组 (3.9%对4.3%,P = .02) 中较低.
结论:
- 在患有T2DM的绝经后妇女中,BMAT的含量和组成受到改变.
- 这些BMAT变化是特定的,在股骨头和L3脊椎有显著差异.
- 该研究确定了与T2DM相关的BMAT变化的基于成像的特定标记物.

Carbohydrate Metabolism
10.8K
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...

Diabetes Mellitus: Type 2 and Gestational
2.2K
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...

Pathophysiology of Diabetes
881
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 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...

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...

Bone Disorders
3.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
