概括
在怀孕中期的血清胎盘生长因子 (PlGF) 测试在与临床风险因素相结合时,不能改善检测不良妊娠结果. 这种策略不推用于常规使用,因为它的预测值很差.
科学领域:
- 孕产妇和胎儿的医学
- 产科 产科 产科 产科 产科
- 生殖医学是一种生殖医学.
背景情况:
- 怀孕不良后果对母亲和婴儿的健康构成重大风险.
- 早期识别高风险妊娠对于及时干预至关重要.
- 目前的查方法,包括临床风险因素,在准确预测不良结果方面存在局限性.
研究的目的:
- 评估血清胎盘生长因子 (PlGF) 测试在怀孕19-23周的有效性,以改善对有不良结果风险的怀孕的识别.
- 评估单独和结合临床风险因素的PlGF测试的诊断性能.
主要方法:
- 在两个英格兰产科单位进行的前性观察队列研究.
- 包括未经选择的单独怀孕在怀孕19-23周参加例行超声波检查.
- 评估了临床危险因素,包括先兆子和胎儿生长限制,低PlGF (<5百分位数),或两者,与包括先兆子,妊娠高血压,死产和NICU入院的结果相比.
主要成果:
- 在30013例怀孕中,仅仅临床风险因素就能检测出41.7%-54.7%的具有有限预测价值的不良结果.
- 低PLGF检测到8.5%-17.4%的不良结果,并有意义地增加了在37周前分娩的风险.
- "双阶段"查 (风险因素加PlGF) 检测到4.2%-8.9%的不良结果,预测早产的情况有所改善,但预测到期的结果没有.
结论:
- 临床风险因素查具有较高的错误阳性率和不良怀孕结果的检测能力.
- 怀孕19-23周的plGF测试在与临床风险因素一起使用时不会减少假阳性.
- 单独或与临床风险因素结合测试血清PlGF,不建议作为一个有用的查策略,以期不良结果.

Fetal Circulation
1.0K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Gonadal and Placental Hormones
1.5K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
