まとめ
高齢女性は、男性と比較して甲状腺機能障害、結節、自己免疫疾患のリスクが高いことを示しています。この甲状腺の健康における性差は、高齢者のすべてのヨウ素栄養レベルで持続します。
科学分野:
- 内分泌学
- 老年医学
- 公衆衛生
背景:
- 甲状腺機能障害は、高齢化する人口において増大する懸念事項である。
- 標的を絞った健康介入のためには、性別に特有のリスクを理解することが重要である。
- ヨウ素栄養は甲状腺の健康において重要な役割を果たしている。
研究 の 目的:
- 高齢者の甲状腺機能障害における性差を調査すること。
- 高齢者におけるヨウ素レベルと甲状腺の健康との関連を評価すること。
- 高齢女性で有病率が高い特定の甲状腺疾患を特定すること。
主な方法:
- 中国の高齢者3397人を対象とした横断研究。
- 分析のための尿および血液サンプルの収集。
- 甲状腺の体積測定、甲状腺機能およびヨウ素状態の評価のための甲状腺超音波検査。
主要な成果:
- 女性は男性よりも甲状腺結節、甲状腺腫、甲状腺抗体陽性、甲状腺機能障害の有病率が有意に高かった。ヨウ素栄養レベルの上昇は、両性において甲状腺機能障害の有病率の上昇と相関していた。高齢女性は、甲状腺結節、甲状腺腫、甲状腺抗体陽性、甲状腺機能障害の有病率が有意に高かった。
結論:
- 高齢者の甲状腺の健康における有意な性的二形性が存在する。
- 女性は一貫して甲状腺機能障害、結節、自己免疫疾患のより大きなリスクを経験する。
- これらの性差は、ヨウ素栄養レベルに関係なく明らかである。

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Synthesis and Regulation of Thyroid Hormones
7.0K
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...

Drug Dosing: Geriatric Patients
199
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

The Thyroid Gland
6.5K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age
172
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

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...
