まとめ
長期にわたる高血糖値は,特に高齢者の脳内リンパ機能の低下と関連しています. 血糖をコントロールすると,脳の健康とリンパ系機能が守られます.
科学分野:
- 神経科学
- 内分泌学
- 放射線科
背景:
- リンパ系は脳から 廃棄物を除去します
- 長期にわたる高血糖のリンパ機能への影響は十分に理解されていません.
研究 の 目的:
- 血糖の累積値と脳のリンパ機能の関連性を調べる
- 血管周空間 (DTI-ALPS) 沿いの拡散テンサー画像分析を使用して,リンパ関節機能を評価する.
主な方法:
- コミュニティベースの多センターコホート研究です.
- DTI- ALPSインデックスを用いて,磁気共鳴画像 (MRI) を用いて,リンパ機能の評価を行った.
- 2014年から2018年の累積的な断食血糖 (FBG) は,単一のFBG測定値と比較されました.
主要な成果:
- 長期にわたる高血糖症 (FBG ≥7. 0 mmol/ L) は,より低いDTI- ALPS指数と有意に関連していました.
- この関連性は60歳以上の方や 薬を飲まない方においてより顕著でした.
- 短期的なFBG測定と有意な関連性は見つかりませんでした.
結論:
- 長期にわたる高血糖症は,特に高齢者のリンパ機能を損なう.
- 血糖値をコントロールすると,リンパ管の機能が保たれ,脳の健康が促進されます.

Diabetes: Symptoms, Diagnosis, and Complications
685
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Diabetes Mellitus: Type 2 and Gestational
2.9K
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...

Glucose Transporters
24.1K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Diabetes Mellitus: Overview and Type I Subtype
3.2K
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...

Pathophysiology of Diabetes
1.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Glucose Homeostasis: Regulation of Blood Glucose
2.5K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...
