概括
系统性炎症,由高灵敏度C反应蛋白 (hsCRP) 表示,与老年人的脆弱性有关. 升高的hsCRP水平与较高的脆弱指数得分和较高的脆弱概率有关,支持其作为生物标志物的使用.
科学领域:
- 老年学是指老年学的学科.
- 生物标志物 生物标志物
- 炎症 炎症是一种炎症.
背景情况:
- 系统性轻度炎症可能会导致虚弱.
- 之前对脆弱生物标志物的研究,如C-反应蛋白 (CRP),由于样本大小小,存在局限性,并专注于表型脆弱性.
研究的目的:
- 在全国代表性老年人样本中调查血清高灵敏性C反应蛋白 (hsCRP) 水平与脆弱性之间的关联.
- 评估hsCRP作为检测脆弱性的潜在生物标志物的实用性.
主要方法:
- 这是一项对来自韩国国家健康和营养检查调查的5359名65岁以上参与者的横截面分析.
- 使用38项涵盖身体,认知,心理和社会领域的项目生成了赤字积累脆弱性指数 (FI).
- 测量和分析血清hsCRP水平与脆弱状态 (非脆弱,脆弱前,脆弱) 和FI分数相关,并对各种混因素进行调整.
主要成果:
- 血清hsCRP水平在脆弱的参与者中比非脆弱个体高29.4% (p=0.001),经过对混因素进行调整后.
- 循环hsCRP度与脆弱指数正相关 (p=0.003).
- 较高的hsCRP水平与脆弱的几率增加有关,最高四分位数与最低四分位数 (p=0.001) 相比,几率比率增加了1.59倍.
结论:
- 与年龄相关的全身轻度炎症显著影响老年人的脆弱性.
- 血清hsCRP是一种有价值的潜在生物标志物,用于识别老年人群中的脆弱性.

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:19The Effect of Aging on Tissues
2.1K
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...

01:26Factors Affecting the Risk of Infection
11.5K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

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...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
