- 流行病学 流行病学
- 整形外科 整形外科 整形外科
背景情况:
- 骨关节炎 (OA) 是一种普遍存在的全球性关节疾病,具有显著的个人和社会影响.
- 观察性研究表明,步行速度 (WP) 和OA风险之间存在联系,但因果关系尚不清楚.
- 了解因果关系对于制定有效的预防策略至关重要.
研究的目的:
- 研究遗传预测步行速度 (WP) 与骨关节炎 (OA) 风险之间的因果关系.
- 检查WP与整体OA的关联,以及其亚型:膝盖OA和部OA.
- 评估影响WP-OA关系的潜在混因素.
主要方法:
- 一个大规模的门德尔随机化 (MR) 研究,利用欧洲全基因组协会研究的数据.
- 采用与WP相关的单核酸多态 (SNPs) 作为工具变量.
- 使用反变量加权 (IVW) 作为主要分析,支持MR-Egger,加权中位数和最大概率方法.
- 进行了异质性和类型的灵敏性分析,以及用于混调整的多变量MR (MVMR).
主要成果:

Genome-wide Association Studies-GWAS
13.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Peripheral Artery Disease I: Introduction
9
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs but also impacts other areas, such as the arms, thereby impairing overall circulation and organ function.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty deposits inside the arterial...
