概括

对于怀孕年龄小的新生儿 (SGA) 的甲状腺刺激激素 (TSH) 水平高于适合怀孕年龄的新生儿 (AGA). 为SGA婴儿量身定制TSH查切断值可能会改善先天性甲状腺功能低下症的检测,并减少不必要的召回.

科学领域:

新生儿内分泌学新生儿内分泌学
儿科查协议儿科查协议
增长和发展研究研究.

背景情况:

甲状腺激素对新生儿发育至关重要.
怀孕年龄较小的新生儿面临甲状腺功能障碍的风险增加.
目前的查实践可能无法在SGA婴儿中最佳地识别甲状腺问题.

研究的目的:

为了比较SGA中的甲状腺刺激激素 (TSH) 和自由甲状腺素 (FT4) 水平与适合妊娠年龄 (AGA) 的新生儿.
评估对新生儿甲状腺功能低下症查方案的影响.
调查影响新生儿TSH和FT4水平的因素.

主要方法:

在印度南部对756名新生儿 (268名SGA,488名AGA) 进行了回顾性横截面研究.
血清TSH和FT4水平的分析,测量在生命的48-72小时.
使用芬顿的生长图表,SGA定义为出生体重低于第10百分位.

主要成果:

与AGA新生儿 (中位数4.09mIU/L) 相比,SGA新生儿的TSH水平显著更高 (中位数5.33mIU/L).
需要召回的TSH升高 (>10mIU/L) 在SGA婴儿中更频繁 (18%对8%).
在SGA和AGA组之间,FT4水平是可比的;SGA状态,低出生体重和剖腹产预测了更高的TSH.

结论:

SGA新生儿在48-72小时内显示TSH水平升高,这表明潜在的甲状腺功能障碍风险.
可比的FT4水平表明,TSH是SGA婴儿甲状腺变化更敏感的标志物.
为SGA新生儿开发定制的TSH查切断值可以提高查效率并减少不必要的干预.

Functions of Thyroid Hormones

Functions of Thyroid Hormones

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

Synthesis and Regulation of Thyroid Hormones

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...

The Thyroid Gland

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
