PLoS One:臭氧浓度升高与卒中发生增加相关

2016-05-31 phylis 译 MedSci原创

背景:日益升高的臭氧浓度已破坏人类健康和生态系统。尽管臭氧呈现昼夜变异,多数研究报告当天或后一天缺血性脑卒中的发生,仅白天臭氧浓度相关。研究者调查了臭氧的昼夜变化对缺血性卒中发生的影响。方法:研究者在韩国汉城的一家三级医院,招募2008年1月1日到2014年12月31日的1734例患者。研究者评估每个时间段和平均参数(7年的研究中获得),卒中发生时温度和污染物的差异。结果:相比于其他时间段,13:

背景:日益升高的臭氧浓度已破坏人类健康和生态系统。尽管臭氧呈现昼夜变异,但多数研究报告当天或后一天的缺血性脑卒中发生,仅与白天臭氧浓度相关。研究者调查了臭氧的昼夜变化对缺血性卒中发生的影响。

方法:研究者在韩国汉城的一家三级医院,招募2008年1月1日到2014年12月31日的1734例患者。研究者评估每个时间段和平均参数(7年的研究中获得),卒中发生时温度和污染物的差异。

结果:相比于其他时间段,13:00至16:59时间段内,研究者发现缺血性脑卒中发生和臭氧浓度呈显著的正相关。与较低水平相比,13:00至16:59较高水平平均臭氧水平与缺血性脑卒中呈正相关(OR,1.550;95%CI 1.220到1.970)。

结论:结果表明,缺血性卒中发生的昼夜模式基于24小时较高和较低的平均臭氧水平,这加深了对卒中发生和环境影响相关性的理解。

Environ Res:空气污染与缺血性卒中相关存在种族差异

目的:为了调查空气污染(PM2.5和臭氧)短期改变与有住在一个具有两个种族的地方的人群发生缺血性卒中的风险相关性,评估是否这种相关有种族差异。方法:研究者2000年到2012期间的BASIC计划中识别缺血性卒中的患者。测量同一天或者滞后1-3天的PM2.5(24h)和臭氧(8h最大值)的水平,并且应用条件Logistic回归中时间分层交叉设计模型评估环境污染和急性缺血性卒中发生的相关性。研究者探究
