概括
早期多发性硬化症 (MS) 复发强烈预测残疾恶化,而残疾恶化预测未来的复发. 疾病修饰疗法 (DMT) 随着时间的推移,在复发性MS (ROMS) 中降低了这些风险.
科学领域:
- 神经学 神经学
- 临床研究 临床研究
- 纵向研究 纵向研究
背景情况:
- 多发性硬化症 (MS) 复发和残疾恶化之间的相互作用尚未完全理解.
- 疾病修饰疗法 (DMT) 可能会影响复发性MS (ROMS) 的这种关系.
- 研究这些相互作用为MS的发病和治疗提供了洞察力.
研究的目的:
- 检查MS复发,DMT和ROMS中残疾恶化之间的间接联系.
- 确定早期复发或残疾恶化是否预测未来的结果.
- 评估DMT持续时间对这些关联的影响.
主要方法:
- 利用了来自279个首次脱髓化事件的个体的前性数据,并对其进行了长达15年的跟踪.
- 使用纵向和生存数据的联合模型来估计间接关联参数.
- 分析了时间动态生存概率,以评估未来的风险.
主要成果:
- 早期复发 (在2.5年内) 预测早期残疾恶化 (HR=3.45),但没有长期恶化 (HR=0.21).

This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
