概括
在健康的活产后,短暂的妊娠间隔 (不到18个月) 或长期的妊娠间隔 (36个月或更长) 与随后自发流产 (SA) 的风险更高有关. 计划怀孕间隔对于生殖健康至关重要.
科学领域:
- 生殖健康 生殖健康
- 围产期结局的结果
- 流行病学 流行病学
背景情况:
- 妊娠间隔 (IPI) 是一个已知的可修改的危险因素,对不良的围产期结局.
- 生产后的IPI与随后的自发流产 (SA) 之间的关联需要进一步调查.
研究的目的:
- 调查健康活产后的妊娠间隔 (IPI) 与随后自发流产 (SA) 的风险之间的关联.
主要方法:
- 在中国对180,921名年龄在20-49岁的女性进行前性队列研究.
- IPI分类为<18个月,18-23个月,24-35个月,36-59个月和≥60个月.
- 用于分析SA风险和剂量-反应关联的物流回归模型和受限立方线.
主要成果:
- 在IPI和SA风险之间观察到一个J形的关联.
- 与18-23个月的IPI相比,短期 (<18个月) 和长期 (≥36个月) 的IPI都与SA风险增加有关.
- 具体来说,IPI<18个月 (OR,1.15) 和IPI≥36个月 (ORs从1.28到2.13) 显示SA的几率明显更高.
结论:
- 在健康活产后的妊娠间隔时间短于18个月或长于36个月,与随后自发流产的风险增加有关.

Development of Immunocompetence
301
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

In Vitro Fertilization
239
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Ovarian Cycle
1.1K
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...

Meiosis II
183.3K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...

Teratogenicity
2.4K
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...
