科学领域:

  • 老年学是指老年学的学科.
  • 遗传学 是一个遗传学.
  • 流行病学 流行病学

背景情况:

  • 人口研究表明,狂妄症和皮症之间存在关联,但因果关系尚不清楚.
  • 了解因果关系对于有效的预防和治疗策略至关重要.
  • 研究药物使用在这些疾病中的作用也很重要.

研究的目的:

  • 通过使用孟德尔随机化来研究痴呆症和皮症之间的因果关系.
  • 为了探索药物使用对妄和萨科佩尼亚的因果关系.
  • 为了澄清药物的潜在调解作用在 Delirium-sarcopenia 关系.

主要方法:

  • 使用公共全基因组关联研究 (GWAS) 数据进行双向双样本孟德尔随机化 (MR) 分析.
  • 作为主要分析的反变量加权 (IVW) 方法,支持加权中位数和加权模式.
  • 进行了敏感性分析,包括科克兰的Q测试,MR-Egger回归,MR-PRESSO和留出一个方法.

主要成果:

  • 基因预测的手握强度低,与妄想有因果关系 (OR=1.31,P=0.032).
  • 利尿剂和葡萄糖皮质类药物与尾肌瘦质相关;糖尿病药物和免疫抑制剂与手握强度低相关.
  • 灵敏度分析证实了主要发现,尽管有异质性和性质的证据.

结论:

  • 有证据表明,手握强度低 (肉症) 和妄想之间存在因果关系.
  • 药物使用似乎并没有调解缩症和痴呆症之间的因果关系.
  • 建议进行进一步的大规模人口研究以验证这些发现.
