空气污染伤大脑:降低脑容量 增隐匿性脑梗死风险

2015-04-29 小田 译 cmt

既往研究表明,长期暴露于污染的空气中与脑血管疾病和认知损害有关,但是否与大脑结构变化有关尚不清楚。近期,美国一项研究表明,暴露于PM2.5水平升高的环境与人体总脑容量较小有关,后者是年龄相关脑萎缩的标志,同时还能导致隐匿性脑梗死发生率较高。研究结果提示,空气污染可能对人体大脑结构老化有潜在有害的影响,甚至是对无痴呆和卒中的人群也存在上述影响。相关论文4月23日在线发表于《卒中》(Stroke)杂志

既往研究表明,长期暴露于污染的空气中与脑血管疾病和认知损害有关,但是否与大脑结构变化有关尚不清楚。近期,美国一项研究表明,暴露于PM2.5水平升高的环境与人体总脑容量较小有关,后者是年龄相关脑萎缩的标志,同时还能导致隐匿性脑梗死发生率较高。研究结果提示,空气污染可能对人体大脑结构老化有潜在有害的影响,甚至是对无痴呆和卒中的人群也存在上述影响。相关论文4月23日在线发表于《卒中》(Stroke)杂志。



研究纳入了弗明翰子代研究年龄至少60岁且无痴呆和卒中的受试者。评估暴露于空气细颗粒物(PM2.5)和居住在公路要道与受试者总脑容量、海马体积、脑白质高信号体积和隐匿性脑梗死的关系。校正年龄、临床变量、社会经济学等因素。结果显示,PM2.5每增加2-μg/m3与总脑容量下降0.32%和隐匿性脑梗死发生率增加46%有关。

PLOS Med:空气污染或使儿童认知功能降低

据发表在本周的PLOS Medicine杂志上的一篇文章报道称,在巴塞罗那,7-10岁在校儿童恐会因暴露在由于交通因素引起的空气高度污染中而导致认知能力降低。 研究者测量了39所学校的2715名小学生的三种认知功能(工作记忆、优秀的工作记忆和注意力),12个月内每3个月测量一次。在社会经济条件等外环境类似的情况下,将暴露到空气高污染中的小学生与暴露到空气低污染中的小学生

PLOS MED:交通空气污染影响儿童认知发展

空气污染被认为具有神经毒性。在动物实验中国,吸入汽车尾气和超细颗粒会导致大脑内细胞因子表达和氧化应激增加,以及改变动物的行为。如果妊娠期或者婴儿期暴露在交通相关的空气污染物中,当大脑新皮质迅速发育时,会导致认知延迟。 许多学校位于繁忙道路附近。当儿童在校时,交通空气污染达到顶峰。对于在校儿童暴露于交通空气污染中是否与损失性认知发展有关,科研人员进行了相关研究。科研人员对来自于巴塞罗那的39个学校

EHP:苍穹之下,孩子的认知也会受影响

柴静力作“苍穹之下”让众说周知的“空气污染影响人类身体健康”深入人心,痛彻心扉。可是雾霾之下,孩子认知发育又会如何动荡,仍是扑溯迷离。近期Harris MH等人进行了一项调查研究,为我们初步揭开了谜的面纱。

ACC 2015:空气污染增颈动脉狭窄风险

全球心血管医生的学术盛会——美国心脏病学会年会(ACC2015)将于3月14~16日在美国圣迭戈召开。纽约大学Langone医学中心的一项研究显示,居住在空气污染更严重地区的居民发生颈动脉狭窄的风险更大。颈动脉狭窄与美国每年超过一半的卒中相关。该研究将在ACC2015中公布,并将同步发表于《美国心脏病学会杂志》(JACC)。已有研究显示,空气污染与心血管疾病相关,但大多数研究都集中在空气污染与心脏

EHP:空气污染可能增加妊娠期糖尿病的发生

妊娠期糖尿病(gestational diabetes mellitus,GDM)是妊娠期才出现的糖尿病,而妊娠前糖代谢正常,大部分孕妇妊娠结束后糖代谢可恢复正常,其对孕产妇和胎儿影响较大。妊娠期糖尿病(GDM)会使孕妇妊娠期并发症增加,如妊娠期高血压疾病、羊水过多、巨大儿、肩难产等。并且孕产妇及新生儿远期发生2型糖尿病(T2DM)和其他代谢综合征发病风险增加。虽然GDM的发生率因种族、地域、以及
