概括
这项研究发现,由国际饮食质量指数 (DQI-I) 衡量的整体饮食质量与伊朗成年人患上刺激性肠综合征 (IBS) 的几率之间没有联系. 较高的DQI-I得分并没有降低IBS风险.
科学领域:
- 胃肠病学 胃肠病学
- 营养科学 营养科学
- 流行病学 流行病学
背景情况:
- 刺激性肠综合征 (IBS) 是一种普遍存在的肠-大脑疾病,其原因尚不清楚,尽管饮食是一个重要的因素.
- 以前的研究集中在单个营养素上,忽视了整体饮食质量对IBS的影响.
- 国际饮食质量指数 (DQI-I) 评估了整体饮食质量,考虑了食物组的相互作用.
研究的目的:
- 调查饮食质量指数-国际 (DQI-I) 评分与伊朗成年人易性肠综合征 (IBS) 的几率之间的关联.
- 评估较高的DQI-I得分是否与IBS的几率降低相关.
- 探索DQI-I和IBS之间的性别特定关联.
主要方法:
- 一项涉及100名IBS患者和310名来自伊朗的健康对照者的病例控制研究.
- 饮食摄入量使用经过验证的基于菜的半定量性食物频率问卷 (DB-FFQ) 进行评估.
- 通过罗马IV问卷的波斯语版本确认IBS诊断;使用多变量逻辑回归计算和分析DQI-I得分.
主要成果:
- 在对混因素进行调整后,在DQI-I得分和整体组内IBS的几率之间没有发现显著的关联.
- 性别分层分析也显示DQI-I和IBS几率之间没有显著的联系.
- 较高的DQI-I得分,表明更健康的饮食,与本研究人群中IBS的可能性较低无关.
结论:
- 这项研究表明,通过DQI-I测量的整体饮食质量可能与伊朗成年人IBS的几率降低无直接关联.
- 这些发现突出了进一步研究的必要性,因为对DQI-I和IBS的证据有限.
- 建议进行大规模的前性研究来验证这些结果,并澄清饮食质量在IBS病因学中的作用.

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
209
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:

Drugs for Treatment of Diarrhea-Predominant IBS
126
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
