概括
孕期第二个三个月的孕产妇胎盘生长因子 (PIGF) 水平是出生小于妊娠年龄 (SGA) 的婴儿的强有力的预测因素. 低水平的PIGF显著增加了SGA的风险,为早期检测提供了潜在的新生物标志物.
科学领域:
- 围产科和新生儿科 围产科和新生儿科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 生物标志物发现发现
背景情况:
- 目前用于预测怀孕年龄 (SGA) 较小出生婴儿的临床生物标志物缺乏可访问性,准确性和安全性.
- 迫切需要可靠的方法来识别有SGA婴儿风险的怀孕.
研究的目的:
- 调查母体血清胎盘生长因子 (PIGF) 水平对SGA婴儿发生的预测能力.
- 确定PIGF是否可以作为SGA的独立风险因素.
主要方法:

- 在怀孕的第二个三个月内监测母亲的血清PIGF水平.
- 应用多重物流回归和接收机运行特征 (ROC) 曲线分析.
主要成果:
- 在第二个三个月内,母亲的低PIGF水平被确定为SGA的显著独立风险因素 (HR = 26.417,p < 0.001).
- 其他独立因素包括多对性,孕前孕产妇体重不足,子宫前,和橄水.
- PIGF表现出强大的预测值 (AUC = 0.834),与其他因素相结合时进一步增强 (AUC = 0.902).
结论:
- 怀孕第二季度母亲血清PIGF水平较低,是SGA的强有力的独立风险因素.
- 与其他评估指标相比,PIGF是SGA的优越预测指标.
- 将PIGF与其他临床因素结合起来,显著改善了SGA出生的预测.

01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
03:09Meiosis I
Meiosis is the division of a diploid cell into haploid cells forming sperm and eggs in animals through differentiation. Meiosis I is the first stage of meiosis, where the genetic recombination of homologous chromosomes and the reduction of the ploidy level by half occurs.
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...

02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:07Teratogenicity
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...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
