概括
减少从三胞胎到双胞胎的多胎妊娠改善了与继续三胞胎相比,妊娠年龄和出生体重等出生结果. 然而,减少三胞胎的结果仍然比32周怀孕前自发双胞胎更糟糕.
科学领域:
- 生殖医学 生殖医学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 周围生理学 周围生理学
背景情况:
- 辅助生殖技术和增加的母亲年龄导致了更多的多胎妊娠.
- 多重怀孕,特别是高阶怀孕,对母亲和孩子都有很大的风险.
- 多胎妊娠减少 (MPR) 选择性地减少胎儿数量,以改善剩余胎儿的结果.
研究的目的:
- 为了比较降低到双胞胎的三子双胞胎与继续三子双胞胎的出生结果.
- 为了比较减少三胞胎与初级二二双胞胎的出生结果.
主要方法:
- 使用东弗兰德斯前双胞胎调查 (1990-2016) 数据进行的回顾性队列研究.
- 相比之下,85例三子妊娠减少到双胞胎,5093例初级二子双胞胎怀孕和104例预期管理的三子怀孕.
- 评估结果包括分娩时的妊娠年龄,出生体重和对于妊娠年龄的小 (SGA).
主要成果:
- 从三胞胎到双胞胎的MPR导致与持续三胞胎相比,出生体重和妊娠年龄显著增加.
- 与持续三胞胎相比,MPR降低的三胞胎显示出SGA风险较低的趋势.
- 与初级双胞胎相比,减少的三胞胎的出生体重和妊娠年龄较低,在怀孕32周后没有显著差异.
结论:
- 从三三胞胎到双胞胎的MPR显著改善了分娩结果,使其在医学上得到证明.
- 虽然MPR改善了结果,但在32周之前出生的初级双胞胎仍然比减少的三胞胎有更好的结果.
- 预防更高阶怀孕是可取的,因为MPR本质上涉及胎儿损失.

Ovarian Cycle
1.3K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Teratogenicity
2.5K
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...
