概括
非腹性谷蛋白敏感性 (NCGS) 是一种患者在食用谷蛋白后出现症状,但没有腹性疾病或小麦过敏. 研究表明可发酵的碳水化合物和心理因素对症状有很大影响,
科学领域:
- 胃肠病学
- 临床营养
- 营养学
背景情况:
- 非乳性谷蛋白敏感性 (NCGS) 影响了从摄入谷蛋白或小麦而来的症状,与乳性疾病或小麦过敏不同.
- 虽然约10%的成年人自我报告质敏感性,但有控制的研究表明16-30%的人有质特异性的触发因素,尽管方法是可变的.
- 可发酵碳水化合物和nocebo效应与症状产生有关,以及商业和媒体对研究和感知的影响.
研究的目的:
- 对NCGS作为一个独立实体的现有证据进行批判性审查.
- 探索NCGS症状的潜在机制.
- 为NCGS的评估和管理提供实际指导.
主要方法:
- 对NCGS现有的文献进行系统审查.
- 诊断挑战的分析,包括缺乏生物标志物和与肠-大脑相互作用障碍的重叠.
- 评估饮食评估方法及其局限性
主要成果:
- 由于缺乏生物标志物和方法变异性,对NCGS的最终诊断具有挑战性.
- 可发酵的碳水化合物和nocebo效应在症状的发展中起着相当大的作用.
- NCGS仍然是一个需要仔细评估的排除诊断.
结论:
- 诊断NCGS是难以捉摸的,需要系统的方法平衡饮食变化与心理因素和营养充足.
- 需要进一步的研究来确定病因和开发诊断测试.
- 管理需要承认不确定性,并专注于个性化护理.

Glucose Transporters
27.2K
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:

Other Disorders of Digestive System
1.4K
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
635
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Hypoglycemia and Glucagon
826
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Taste Buds and Receptors
4.6K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Hypersensitivities
7.2K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...
