概括
用光学连贯断层扫描 (OCT) 测量下部中心视网膜体积 (CRV) 是老年人死亡风险的预测指标. 这一发现独立于心血管疾病和其他常见的健康因素.
科学领域:
- 眼科医生 眼科 眼科
- 老年学是一门学科.
- 公共卫生 公共卫生
背景情况:
- 光学连贯断层扫描 (OCT) 是一种非侵入性成像技术.
- 中央视网膜体积 (CRV) 可以自动从OCT扫描中得出.
- 预测老年人死亡率的因素对公共卫生有重大意义.
研究的目的:
- 调查视网膜中枢体积 (CRV) 与全因死亡风险之间的关联.
- 评估CRV作为德国老年人队列中潜在的死亡预测因子.
- 确定这种关联是否独立于心血管疾病.
主要方法:
- 基于人口的前性队列研究 (AugUR) 对2,166名70-95岁的个人进行了研究.
- 用于海德堡光谱衍生CRV测量的光谱域OCT.
- 卡普兰-梅尔曲线和考克斯比例危险回归分析了平均5.9年随访期间的死亡率.
主要成果:
- CRV的下降与全因死亡风险的增加有关 (HR 1.17 per SD较低的CRV).
- 这一关联对于非心血管死亡原因 (HR 1.25) 仍然很重要.
- 这种联系在超过预期寿命的个体中更为明显.
结论:
- 较低的CRV,很容易从OCT获得,是老年人潜在的死亡预测因子.
- 这种预测值独立于心血管疾病.
- 在老年人群中,CRV可以作为一种新的生物标志物来评估老年人群死亡风险.

The Effect of Aging on Tissues
3.6K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
868
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
