概括
严重的胰岛素耐药性 (IR) 显著增加了乳头甲状腺癌 (PTC) 的风险. 然而,该研究没有发现PTC特征在不同的IR严重程度之间存在差异,这表明需要进一步研究.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 胰岛素高血压和胰岛素抵抗 (IR) 与癌症风险增加有关.
- 严重的IR,在像脂质营养不良等疾病中见到,与早期发生的甲状腺结节和乳头甲状腺癌 (PTC) 有关.
研究的目的:
- 调查严重IR患者中PTC的患病率和临床病理特征.
- 为了比较严重IR,轻度IR和euglycemic对照的队列中的PTC特征.
主要方法:
- 在严重的IR患者中比较PTC患病率与来自SEER数据库的美国人口数据.
- 对70名PTC患者进行了横截面分析 (6名严重IR患者,13名2型糖尿病患者,51名对照患者),评估瘤特征和免疫组织化学.
主要成果:
- 与一般人群 (0.29%) 相比,PTC患病率在严重IR (2.2%) 中显著高于一般人群 (0.29%).
- 严重IR患者在诊断时 (26岁) 比轻度IR或对照患者年轻.
- 在IR组之间没有观察到瘤大小,亚型,转移潜力或特定分子标记物 (IGF-1R,SMA,BRAF) 的显著差异.
结论:
- 严重的IR综合征与患乳头甲状腺癌的风险增加有关.
- 尽管风险增加,但PTC特征不会根据胰岛素抵抗的严重程度而有所不同.
- 需要进一步的研究来阐明将严重的IR与PTC发展联系在一起的机制.

Diabetes Mellitus: Overview and Type I Subtype
4.8K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Insulin: The Receptor and Signaling Pathways
2.6K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

Insulin: Dosing Regimen and Adverse Effects
644
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes Mellitus: Type 2 and Gestational
4.2K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Carbohydrate Metabolism
13.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

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...
