まとめ
2型糖尿病患者の内臓脂肪の蓄積は神経損傷と関連しています. 133. 9cm2の内臓脂肪の領域は,大きな神経繊維の機能不全のリスクを大幅に増加させる.
科学分野:
- 内分泌学
- 神経学
- メタボリックシンドローム
背景:
- 肥満は糖尿病周辺神経症 (DPN) の危険因子として知られていますが,正確な関係については議論されています.
- 代謝機能障害の重要な指標である内臓脂肪の蓄積は,DPNの発達において重要な役割を果たす可能性があります.
研究 の 目的:
- 振動知覚値 (VPT) によって評価された内臓脂肪領域 (VFA) と大きな神経繊維機能障害との関連を調査する.
- 2型糖尿病 (T2DM) の若い中年の中国人患者におけるこの関係を解明する.
主な方法:
- 501人のT2DM患者 (18~65歳) の横断研究が行われました.
- 腸内脂肪面積 (VFA) は,生物電気阻力分析を用いて測定された.
- 大量の神経繊維の機能障害は,多変数ロジスティック回帰と円滑な曲線フィッティングを含む統計分析を用いて,振動感知値 (VPT) を測定した.
主要な成果:
- VFAとVPTの間で非線形J型関連が観察されました.
- 133. 9cm2のVFAで有意な値効果が確認された.
- 133. 9cm2以上のVFAでは,10cm2の増加が異常VPTのリスクを22%増加させた (OR=1. 22).
結論:
- T2DM患者の内臓脂肪の蓄積と大きな神経繊維の機能不全はJ型曲線に沿っています.
- 133. 9cm2のVFA値を超えると,神経機能障害のリスクが著しく上昇します.

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,...

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...

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...

Carbohydrate Metabolism

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Diabetes: Symptoms, Diagnosis, and Complications

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...
