概括

这项研究发现,伊朗老年人的黄斑厚度和体积受性别和年龄的影响. 女性的斑点厚度较低,体积随着年龄的增长而减少,突出显示了视网膜测量中的基于性别的差异.

科学领域:

眼科医生眼科眼科
老年医学老年医学
视网膜成像视网膜成像

背景情况:

斑点的厚度和体积是视网膜健康的关键指标.
了解不同人群中的规范价值对于诊断眼睛疾病至关重要.
伊朗老年人群中黄斑参数的数据有限.

研究的目的:

确定60岁及以上的健康伊朗人的黄斑厚度和黄斑体积的分布.
在这个人群中确定斑点测量的人口和生物识别决定因素.

主要方法:

在伊朗德黑兰使用了多阶段分层随机集群采样方法.
参与者接受了全面的光学检查和光学生物识别.
视网膜成像使用光谱域光学连贯性断层扫描 (SD-OCT) 进行.

主要成果:

平均中央斑点厚度 (CMT) 为221±33μm,平均斑点厚度 (AMT) 为267±29μm,斑点体积为8.36±0.44mm3.
与男性相比,女性的CMT,AMT和黄斑体积显著降低.
黄斑体积随着年龄的增长而减少,并与轴长和角质量学相关.

结论:

伊朗老年人群中的斑点厚度略低于其他研究群体.
性别是斑点厚度和体积的重要决定因素,需要在临床解释中考虑.
年龄和生物识别因素也在斑点体积变化中起作用.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

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...
