概括
产前暴露于细颗粒物 (PM2.5) 会增加产后抑郁症 (PPD) 的风险,特别是在经历低感知压力或高负面生活事件的母亲身上. 这凸显了压力评估在识别危险怀孕中的重要性.
科学领域:
- 环境健康 环境健康
- 生殖健康 生殖健康
- 精神病学是一个精神病学.
背景情况:
- 产后抑郁症 (PPD) 是一个重要的全球健康问题,影响着母亲的福祉.
- 以前的研究将产前暴露于细颗粒物 (PM2.5) 与增加PPD风险联系在一起.
- 心理社会压力作为这种关系的修饰因素的影响仍然不清楚.
研究的目的:
- 调查心理社会压力 (负面生活事件和感知压力) 对产前PM2.5暴露和PPD之间的关联的改变作用.
- 为了评估不同类别的抑郁症的PPD风险:慢性,新发作和流行.
主要方法:
- 这项研究使用了PROGRESS队列 (n=475名母亲),通过负面生活事件 (NLE) 和感知压力评分 (PSS) 来测量怀孕压力.
- 产前PM2.5暴露被估计使用一个空间时空模型,平均在怀孕期间.
- 修改Poisson回归分析了PM2.5和PPD之间的关联,由NLE和PSS分层,使用各种爱丁堡产后抑郁量表 (EPDS) 截止值.
主要成果:
- 平均怀孕PM2.5的5μg/m3增加与低PSS的母亲患有流行PPD的风险增加129%有关.

Long-term Depression
33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants
474
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Depression: Overview
934
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
