概括
与健康同龄人相比,患有肠衰竭 (IF) 的儿童在亲肠营养 (PN) 上的体重和身高z-score较低,但相位角度 (PhA) 类似. 这表明PhA可能不反映PN的IF患者的营养状况变化.
科学领域:
- 儿科胃肠病学 儿科胃肠病学
- 营养科学 营养科学
- 生物医学工程 生物医学工程
背景情况:
- 儿童的肠衰竭 (IF) 通常需要长时间的肠道营养 (PN),影响生长和身体组成.
- 阶段角 (PhA),生物电阻分析 (BIA) 参数,是细胞完整性和营养状况的潜在指标.
研究的目的:
- 为了比较通过生物电阻分析 (BIA) 测量的相角 (PhA) 在接受长期肠道营养 (PN) 的肠衰竭 (IF) 的儿童与健康的对照组.
主要方法:
- 一组10岁以下的儿童在60天以上的PN上有IF的研究小组与性别和年龄匹配的对照组进行了比较.
- 评估的人类测量参数包括体重,身高和各种z分数 (W/A,H/A,BMI/A).
- 测量的生物电阻分析 (BIA) 参数是电阻 (R),反应强度 (Xc) 和相角 (PhA).
主要成果:
- 与对照组相比,在PN上患有FI的儿童的体重与年龄 (W/A) 和身高与年龄 (H/A) z分数显著降低.
- 在IF组和对照组之间的相角 (PhA) 中没有发现显著差异.
- 虽然FI组中早产率较高,但妊娠年龄与PhA无关.
结论:
- 长期PN的FI儿童表现出生长障碍 (较低的W/A和H/Az分数),但保持了与健康儿童相似的相角 (PhA).
- 在接受PN的儿科IF患者中,相角 (PhA) 可能不是营养状况变化的敏感指标.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
123
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.

Enteral Nutrition I: Orogastric and Nasogastric Feeding
267
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
331
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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
150
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Intestinal Phase of Digestion
5.1K
The intestinal phase of digestion is the third and final stage of the digestive process, occurring after the cephalic and gastric phases. It begins when chyme, a partially digested mixture of food and digestive enzymes, enters the small intestine from the stomach. This phase is crucial for nutrient absorption and involves complex hormonal and enzymatic interactions.
The arrival of the chyme in the small intestine distends the duodenum, which triggers the enterogastric reflex. This distension...
