概括
对于Clostridioides difficile感染 (CDI) 的便微生物种移植 (FMT) 并没有显著改变基于供体BMI的受体体质量指数 (BMI). 接受者的代谢因素,而不是捐赠者的BMI,似乎影响了FMT后的BMI变化.
科学领域:
- 胃肠病学 胃肠病学
- 微生物组研究 微生物组研究
- 代谢健康 代谢健康
背景情况:
- 便微生物种移植 (FMT) 是对复发性Clostridioides difficile感染 (CDI) 的有效治疗方法.
- 有人猜测,捐赠者的体重指数 (BMI) 可能会影响接受者的BMI,以后用于CDI的FMT.
研究的目的:
- 为了研究供体BMI与接受者BMI在FMT进行CDI后的变化之间的关系.
- 为了确定供体BMI是否影响受体体重变化后FMT.
主要方法:
- 在梅奥诊所 (2012-2019) 对401名因复发性CDI接受FMT的患者进行了回顾性队列研究.
- 分析包括接受者和捐赠者的BMI数据,使用混合效应线性回归来评估BMI变化.
- 卡普兰-梅尔曲线用于评估显著的BMI变化 (≥5单位).
主要成果:
- 捐赠者BMI与接受者BMI的变化没有显著关联.
- 在捐赠者BMI组之间没有观察到BMI增加或减少的显著差异.
- 接受者的FMT前BMI中位数为26.7 kg/m2,而捐赠者的BMI为24.5 kg/m2.
结论:
- 捐赠者的BMI似乎没有显著影响受理者的BMI变化后的FMT为CDI.
- 受体的代谢概况可能在FMT后的BMI变化中起到更为关键的作用.
- 需要进一步的前性,受控试验进行全面分析.

What is Monogastric Digestion?
70.4K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
295
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...

Anatomy of the Intestines
71.2K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Bacterial Flora of the Large Intestine
373
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
