概括
孕产妇的甲状腺功能,特别是甲状腺刺激激素 (TSH) 和自由甲状腺素 (fT4),与妊娠早期的胎盘生物标志物可溶性fms类铁酶-1 (sFlt-1) 和胎盘生长因子 (PlGF) 有关. 与甲状腺自身抗体没有发现任何关联.
科学领域:
- 产科和妇科 产科和妇科

背景情况:
- 孕妇的甲状腺功能在怀孕后果中起着至关重要的作用.
- 胎盘生物标志物可溶性fms-like氨酸激酶-1 (sFlt-1) 和胎盘生长因子 (PlGF) 对于监测胎盘健康至关重要.
- 以前的研究表明,母亲的甲状腺状况与这些胎盘生物标志物之间存在潜在联系.
研究的目的:
- 在怀孕早期,研究母亲甲状腺功能 (TSH,ft4,TPO-Ab,Tg-Ab) 和胎盘生物标志物 (sFlt-1,plGF) 之间的关联.
- 为了确定母体甲状腺自身抗体是否影响sFlt-1和plgf水平.
主要方法:
- 在丹麦北部对858名孕妇进行了回顾性队列研究.
- 从怀孕早期的血液样本中测量TSH,ft4,TPO-Ab,Tg-Ab,sFlt-1和PlGF.
- 回归分析以评估甲状腺功能和生物标志物百分位之间的关联;自抗体的奇平方测试.
主要成果:
- 较高的sFlt-1水平与较低的TSH和较高的FT4相关.

Functions of Thyroid Hormones
2.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones
4.3K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

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...

Gonadal and Placental Hormones
1.3K
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...

Pathophysiology of Diabetes
894
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
