主要方法:
- 一项采用韩国国家健康和营养检查调查数据的横截面研究 (65岁以上的4268名参与者).
- 一个赤字积累脆弱性指数 (FI) 创建了使用38个项目在身体,认知,心理和社会领域.
- 血清UA水平使用彩度酶定量测量.
主要成果:
- 与非脆弱个体相比,脆弱的参与者血清UA水平显著更高 (P < 0.001).
- 血清UA度与FI呈正相关性 (P<0.001),每每1mg/dLUA增加的脆弱率为1.22的几率比率.
- UA水平的最高四分位数与显著更高的FI和1.66倍增加的虚弱概率相关 (P=0.005).
结论:
- 在老年人中,循环UA水平升高可能会促进衰老,而不是提供抗衰老的好处.

01:17Factors Affecting Renal Clearance: Renal Impairment
63
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

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...

01:24Physiology of Urine Formation
3.4K
Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.
Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...

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...

01:11Renal Failure: Dose Adjustments
71
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
