概括
环境肠道功能障碍 (EED) 生物标志物,特别是抗鞭毛蛋白免疫球蛋白A (抗FliC IgA),与危地马拉婴儿的神经发育 (ND) 分数较低有关. 较高的抗FliCIgA水平可能对儿童发育构成重大风险.
科学领域:
- 全球儿童健康 儿童健康
- 儿科神经发育 儿童神经发育
- 胃肠道学和营养学
背景情况:
- 环境肠道功能障碍 (EED) 越来越多地被认为是早期儿童生长和神经发育障碍 (ND) 的贡献者.
- 研究EED的影响对于理解低资源环境中的发展差异至关重要.
- 生物标志物提供了一种可量化的手段来评估EED领域及其对健康的影响.
研究的目的:
- 检查EED生物标志物与危地马拉婴儿的生长和神经发育之间的关联.
- 确定与不良发育结果相关的特定EED标记.
- 为改善受影响人口中儿童发展提供有针对性的干预信息.
主要方法:
- 进行了114名来自危地马拉农村队列的婴儿的横截面研究.
- 在13个月左右,评估了成长 (长度对年龄z-scores) 和神经发育 (早期学习的穆伦尺度).
- 分析了炎症,肠道修复和屏障破坏的血清生物标志物 (包括抗鞭蛋白免疫球蛋白A).
主要成果:
- 在整体队列中,EED生物标志物与生长或神经发育之间没有发现显著的关联.
- 除了患有急性传染性症状的婴儿,发现抗鞭蛋白免疫球蛋白A (抗FliC IgA) 和神经发育分数之间存在显著的负相关性.
- 增加的抗FliC IgA度与较低的早期学习复合 (ELC) 原始分数相关.
结论:
- 肠道屏障的破坏,表明抗FliC IgA的升高,可能会对婴儿的神经发育产生负面影响,特别是在没有急性感染的情况下.
- 较高的抗FliC IgA水平代表了儿童长期健康和认知发育的潜在风险因素.
- 需要进一步的研究来阐明将EED生物标志物与神经发育缺陷联系在一起的机制.

Environmental Influences on Intelligence
881
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Nature and Nurture
22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
