概括
产前酒精暴露 (PAE) 影响认知功能,影响因饮酒模式而异. 每次更高的剂量显著增加了风险,特别是对于不经常饮酒的人来说,挑战了线性剂量反应假设.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 公共卫生 公共卫生
背景情况:
- 大多数研究都假定产前酒精暴露 (PAE) 对认知影响的线性剂量反应.
- 新出现的证据表明非线性效应和模式依赖性影响 (每次剂量,频率).
研究的目的:
- 调查PAE和认知功能之间的非线性剂量反应关系.
- 为了区分每次饮酒剂量与饮酒频率对认知结果的影响.
主要方法:
- 在美国六个纵向队列中,来自2227名参与者的认知功能数据的第二阶段确认因素分析.
- 回归模型比较线性和非参数的一般添加模型 (GAM),使用单个 (绝对酒精/天) 和两个预测指标 (剂量/次数,频率).
主要成果:
- 单个预测器GAM显示了绝对酒精/天的最小非线性.
- 两种预测者GAM显示了模式依赖的效应:更高的剂量/场合强烈影响了不经常饮酒者的后代.
- 剂量/场合影响在非常频繁的饮酒者中最为明显;频率没有显著地改变PAE对低水平饮酒者的影响.
结论:
- 每日总酒精摄入量的线性模型可能足以进行一般的PAE影响评估.
- 鉴定认知障碍需要对每次饮酒剂量和饮酒频率进行详细分析.

Teratogenicity
2.4K
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...

CNS Depressants: Alcohol and Nicotine
205
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
