まとめ
甲状腺代用療法 (TRT) は,甲状腺機能が著しく改善され,甲状腺機能低下や肥満の患者で投与量が減少します. 体重減少は,甲状腺ホルモンのレベルの改善とTRTの需要の減少と相関しています.
科学分野:
- 内分泌学
- 腹部 外科
- 代謝障害
背景:
- 肥満は代謝の不均衡と 甲状腺機能障害に関連しています
- 甲状腺機能低下は代謝の低下と肥満の増加と関連しています.
- 甲状腺ホルモンは,エネルギー消費と体量指数 (BMI) を調節する上で重要な役割を果たします.
研究 の 目的:
- 甲状腺機能低下症と 病的な肥満症の両方の患者に対する 減量手術の影響を評価する.
- 手術後の甲状腺機能の変化と薬剤の必要性を分析する.
主な方法:
- 腹部外科手術を受けた314人の患者を対象とした前向きな比較研究です.
- 患者はユーチロイド (対照群) とヒポチロイド (テスト群) に分けられました.
- 1年間の追跡データを収集し,分析した.
主要な成果:
- 甲状腺機能低下患者 (n=156) は,1年後に全体の体重減少率 (%TWL) を36. 61%達成した.
- 甲状腺刺激ホルモン (TSH) 濃度が手術後に著しく低下した.
- 甲状腺置換療法 (TRT) の投与量は1年後に著しく減少した.
結論:
- 低甲状腺手術は 甲状腺機能の大幅な改善につながります
- 手術後の体重減少は,TSHとFT3レベルと負の相関関係があります.
- 甲状腺ホルモンの濃度の低下は,TRTの必要性の低下と関連しています.

01:18Functions of Thyroid Hormones
3.1K
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...

01:20Synthesis and Regulation of Thyroid Hormones
5.1K
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...

01:17Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:23The Thyroid Gland
4.3K
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...

01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
288
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

01:27Major Hormones and Their Functions

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...
