概括
剩余小肠长度,而不是肠道生物标志物,预测了新生儿的肠道自主性. 与功能性肠衰竭 (IF) 相比,患有短肠综合征 (SBS) 的儿童表现出改变的胆盐合成.
科学领域:
- 儿科胃肠病学 儿科胃肠病学
- 肠道衰竭管理 肠道衰竭管理
- 生物标志物研究 生物标志物研究
背景情况:
- 在肠道衰竭 (IF) 中对肠道营养 (PN) 的依赖会导致肝脏疾病.
- 让患者脱离PN是一种关键的管理目标.
- 功能性肠道参数,如素 (CIT) 和纤维细胞生长因子19 (FGF19),可以预测成年人的胆固醇.
研究的目的:
- 评估CIT,FGF19和尿肠脂肪酸结合蛋白 (I-FABP) 是否预测新生儿在肠道手术后的肠道自主性.
- 在患有长期PN (短肠综合征 (SBS) 和功能IF) 的儿童中分析CIT,FGF19,胆盐和C4的纵向模式.
主要方法:
- 两中心前性队列研究.
- 包括手术后需要PN的新生儿和 (> 6 个月PN依赖的儿童 (< 18 岁).
- 测量了生物标志物 (CIT,FGF19,I-FABP,总胆盐,C4);分析了与考克斯回归和纵向模式与线性混合效应模型的关联.
主要成果:
- 在50名新生儿中,52%的新生儿实现了肠道自主;只有小肠残留长度 (<75厘米) 预测了这一点,而不是生物标志物.
- 患有SBS的儿童 (n=20) 与功能IF (n=20) 相比,FGF19较低,C4较高 (表明胆盐合成失调).
- 在长期PN儿童中,随着PN依赖度的下降,CIT增加,随着PN持续时间的增加,总胆盐增加.
结论:
- 肠道生物标志物没有改善预测新生儿在小肠残余长度之外的肠道自主性.
- 长期PN的SBS儿童表现出增强的胆盐合成.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
858
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
249
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Enteral Nutrition I: Orogastric and Nasogastric Feeding
1.3K
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
185
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

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...
