概括
通过使用现实世界的怀孕数据,为甲状腺刺激激素 (TSH) 和自由甲状腺素 (FT4) 建立了新的三个月特定的参考间隔. 这些从最大概率方法中得出的间隔,与现有指南相比,显示TSH的极限较窄.
科学领域:
- 内分泌学 在内分泌学.
- 生殖医学 生殖医学
- 临床化学 临床化学
背景情况:
- 确立甲状腺激素准确的三个月特定的参考间隔对于在怀孕期间管理甲状腺功能障碍至关重要.
- 现有的指导方针可能无法完全反映甲状腺刺激激素 (TSH) 和自由甲状腺素 (FT4) 水平的现实变化.
研究的目的:
- 通过使用现实世界的数据,在孕妇中确定TSH和FT4的三个月特定的参考间隔.
- 为了将这些新建立的间隔与现有的指南建议的间隔进行比较.
主要方法:
- 利用了2014年7月至2019年12月的非识别妊娠数据,包括TSH,FT4和抗甲状腺过氧化酶抗体 (TPO-Ab).
- 应用最大概率方法对TPO-Ab阴性怀孕在数据清理后确定参考间隔.
- 在分析中包括超过55,000个怀孕记录.
主要成果:
- 建立了TSH (例如,第一个三个月的0.40-4.09mIU/L) 和FT4 (例如,第一个三个月的12.2-20.5 pmol/L) 的三个月特定的参考间隔.
- 最大概率方法衍生的FT4间隔与指导间隔相似,在第一和第二季度略有差异.
- 使用最大概率方法计算的TSH参考间隔比当前指南所建议的更窄.
结论:
- 在怀孕期间使用最大概率方法成功建立了TSH和FT4的三个月具体参考间隔.
- 与现有指导方针相比,新的间隔没有显示FT4的临床显著差异,TSH的临床显著差异和更窄的极限.
- 这些发现支持使用方法衍生间隔来更精确地评估怀孕期间的甲状腺功能.

Synthesis and Regulation of Thyroid Hormones
7.1K
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...

Functions of Thyroid Hormones
4.9K
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...

Regression Toward the Mean
6.8K
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...
