背景情况:
- 孕期化学物质暴露与自闭症谱系障碍 (ASD) 风险有关.
- 之前的研究往往分析有限的化学类或缺乏混合物分析.
研究的目的:
- 用MARBLES队列数据调查多类化学混合物对ASD风险的影响.
- 评估化学混合物和神经发育结果之间的共同调整的多污染物关联.
主要方法:
- 在母体血液/尿液中量化了5个化学类 (PFAS, parabens, , 酸盐, OPEs) 的30个生物标志物.
- 使用等级分类和计算的LDA暴露总结得分来确定化学.

Autism Spectrum Disorder
36
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Mutagenicity and Carcinogenicity
1.1K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Teratogenicity
2.3K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
