概括

这项研究跟踪了早产儿的生长,揭示了不同妊娠年龄的不同轨迹. 新的增长曲线和百分比值为这种脆弱人群提供了更好的评估.

科学领域:

儿科儿科儿科
新生儿科学新生儿科学
增长和发展增长和发展

背景情况:

过早分娩会扰乱胎儿的发育,需要专门的产后护理.
目前早产婴儿的生长标准通常依赖于早产婴儿数据,缺乏纵向研究.
40周的月经后年龄 (PMA) 是一个常见的基准,但早产婴儿的动态生长跟踪尚未得到充分研究.

研究的目的:

为了确定早产婴儿的纵向生长曲线和百分点值.
分析早产婴儿到36个月校正年龄 (CA) 的动态产后生长轨迹.
为了确定不同妊娠年龄 (GA) 群体的生长模式和潜在的增长迟缓.

主要方法:

利用了来自中国的79514名早产婴儿 (2016-2022) 的数据库.
从出生到36个月的年龄修正 (CA) 收集的人类测量测量结果.
采用通用添加模型 (GAM) 来生成增长曲线和百分点值.

主要成果:

怀孕年龄的出生体重与中国标准保持一致.
宫外生长迟缓很普遍,在GA ≤34周组中超过10%的40周PMA,在非常早产婴儿 (VPI) 中达到55.56%.
已建立的生长曲线显示,晚期早产婴儿接近期货标准,而VPI一直落后于期货标准,直到36个月的CA.

结论:

过早出生的婴儿根据妊娠年龄表现出不同的生长轨迹.
开发的生长曲线和百分值为评估早产婴儿生长提供了专门的工具.
这些发现为预产婴儿的生长评估提供了一种改进的方法.

Lung Capacity

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
