概括
益生菌和共生菌补充剂显著降低了炎症标志物,并增加了糖尿病患者有益的肠道细菌代谢物. 这些干预措施,特别是协生菌和更长时间的干预,显示出对管理糖尿病相关炎症的希望.
科学领域:
- 微生物学 微生物学
- 免疫学 免疫学 免疫学
- 代谢过程中的代谢.
背景情况:
- 系统性炎症是糖尿病的关键因素,有助于胰岛素抵抗和疾病进展.
- 肠道微生物群和短链脂肪酸 (SCFA) 越来越多地被认为是它们在免疫调节中的作用.
- 益生菌和共生菌正在研究它们的潜力,以准肠道微生物群并减少炎症.
研究的目的:
- 进行元分析,评估益生菌和共生菌补充剂对1型和2型糖尿病患者炎症标志物和微生物代谢物的影响.
- 确定影响这些干预措施有效性的因素,如配方类型和持续时间.
主要方法:
- 进行了对46项随机对照试验 (RCT) 的元分析,其中涉及3,580名糖尿病患者.
- 随机效应模型被用于评估C-反应蛋白 (CRP),白素-6 (IL-6),瘤缩因子-α (TNF-α),白素-10 (IL-10) 和SCFA水平的变化.
- 亚组分析和元回归研究了干预时间和配方类型等效果修饰因素.
主要成果:
- 益生菌/共生菌干预显著减少了CRP,IL-6和TNF-α,同时增加了IL-10.
- SCFA 含量,特别是酸盐,显著增加.
- 干预的持续时间 (≥8周),同生菌的使用和更高的丁酸盐水平预测了更大的抗炎作用.
结论:
- 有针对性的益生菌和共生菌配方,特别是富含酸盐等SCFA的配方,可以有效地减轻糖尿病的代谢炎症.
- 多菌株协生菌和持续至少8周的干预似乎是最有益的.
- 需要进一步的RCT来确认对血糖和心脏代谢结果的影响.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
637
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...

Irritable Bowel Syndrome I: Introduction
919
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
