概括
增长差异化因子15 (GDF15) 预测了老年人部骨折的发生. 较高的GDF15水平与骨折风险增加相关,可能由肌肉功能减少和肌肉量减少介导.
科学领域:
- 老年学是一门学科.
- 生物标志物 生物标志物
- 整形外科 整形外科 整形外科
背景情况:
- 增长区分因子15 (GDF15) 是一种与衰老和与年龄相关的疾病风险相关的蛋白质.
- 高GDF15水平与增加的死亡率和发病率有关.
- 了解GDF15在骨折等与年龄相关的疾病中的作用至关重要.
研究的目的:
- 调查血清GDF15水平与老年人发生关节骨折之间的关联.
- 在这种关系中探索潜在的介导因素,包括骨矿物质密度 (BMD),肌肉功能和瘦肉质量.
主要方法:
- 从健康衰老和身体组成研究中测量了1174名参与者 (70-79岁) 的血清GDF15水平.
- 数据包括BMD,骨周转指标,身体功能测试 (步行速度,平衡,握力),BMI,肌肉质量和跌倒史.
- 考克斯比例危险模型被用来评估GDF15四分位数的关节骨折风险,平均随访时间为11.5年.
主要成果:
- 平均GDF15在男性中较高,并且随着年龄的增长而增加,步行速度较慢,平衡较差,握力较低.
- 在随访期间,共有93例关节骨折发生,女性的风险较高,年龄较大,BMI较低,BMD较低,肌肉质量较低,握力较弱.
- 最高的GDF15四分位数显示关节骨折风险增加了2倍,在调整年龄和性别后显著,但在调整握力后没有显著.
结论:
- 血清GDF15的增加是老年人骨折的重要预测因素.
- GDF15与关节骨折风险之间的关联可能部分由肌肉功能和肌肉质量介导,但不是BMD.
- GDF15值得进一步研究,因为它可能是老年人群中骨折风险评估的潜在生物标志物.

The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Bone Disorders
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...

Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Role of Hematopoietic Growth Factors
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
