概括
对甲状腺功能障碍的放射性治疗最初增加了死亡率,但这种风险随着甲状腺素 (T4) 治疗而减少. 建议治疗甲状腺功能障碍症以诱导甲状腺功能障碍症和随后的T4替换,特别是如果发生亚临床甲状腺功能障碍症.
科学领域:
- 内分泌学和新陈代谢学
- 心血管健康 心血管健康
- 公共卫生流行病学 流行病学
背景情况:
- 甲状腺功能障碍与所有原因和循环死亡率的升高有关.
- 这种增加的死亡率的可逆性和轻度甲状腺功能障碍或治疗诱导的甲状腺功能低下的影响尚不清楚.
研究的目的:
- 调查甲状腺功能障碍的放射性治疗与死亡率之间的关联.
- 评估使用甲状腺素 (T4) 治疗的轻度甲状腺功能障碍和甲状腺功能低下对死亡结果的影响.
主要方法:
- 一项以人口为基础的队列研究,包括2668名40岁以上的40岁以上的个体,他们因甲状腺功能障碍而接受放射性治疗 (1984-2002).
- 针对英格兰和威尔士的特定原因死亡率与特定年龄和特定时期死亡率的比较.
- 分析T4治疗对放射性诱导的甲状腺功能低下和亚临床甲状腺功能障碍的死亡率的影响.
主要成果:
- 与一般人群相比,放射性治疗组的总死亡率更高 (SMR 1.14).
- 在T4治疗之前或没有T4治疗时观察到增加的死亡风险,但在T4治疗期间没有.
- T4治疗与所有原因 (HR 0.65) 和循环死亡率 (HR 0.65) 的显著降低有关.
结论:
- 甲状腺功能障碍的放射性治疗与死亡率的增加有关,随后的甲状腺素 (T4) 治疗可以减轻这种死亡率.
- 通过足够的放射性剂量诱导明显的甲状腺功能低下症,然后进行T4替代是受支持的.
- 在亚临床的甲状腺功能低下症中,放射性后的治疗可能会增加缺血性心脏病的死亡率,因此需要考虑T4替代.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
179
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Functions of Thyroid Hormones
5.0K
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
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...

The Thyroid Gland
6.6K
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...

Major Hormones and Their Functions
1.7K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Life Tables
491
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
