- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 观察性研究显示,骨矿物质密度 (BMD) 和心血管疾病 (CVD) 之间存在不一致的联系.
- 骨损伤和心血管疾病之间的关系的因果关系仍在争论中.
- 需要强大的方法来澄清这种关联.
研究的目的:
- 评估基因预测的BMD与七种主要心血管疾病之间的因果关系.
- 调查潜在的共同遗传因素影响骨矿物质密度和心血管健康.
- 在BMD-CVD关联中区分直接因果关系与混因素.
主要方法:
- 使用公开可用的全基因组关联研究 (GWAS) 数据进行双样本孟德尔随机化 (MR).
- 利用英国生物库 (初级) 和FinnGen (验证) 队列进行心血管结局.
- 采用逆方差加权 (IVW),加权中位数,加权模式和MR-Egger回归模型,使用MR-Egger Pleiotropy RESidual Sum和Outlier测试进行性评估.
主要成果:
- 在基因预测的BMD和心房动,心痛,缺血性心脏病,心力衰竭,高血压,心肌梗塞或非缺血性心肌病之间没有发现统计学上显著的因果关系.
- 在多种MR分析方法 (IVW,加权中位数,加权模式,MR-Egger) 中,结果一致.

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...

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.
