概括
80%橄油/20%大豆油静脉注射脂类乳液 (ILE) 对儿科患者是安全的,没有显示增加基本脂肪酸缺乏症 (EFAD) 风险. 这一发现支持减少大豆油含量在ILEs中用于需要亲肠道营养的儿童的使用.
科学领域:
- 营养科学 营养科学
- 儿科医学 儿科医学
- 生物化学 生物化学
背景情况:
- 静脉注射脂类乳液 (ILEs) 中大豆油 (SO) 含量下降引发了对必需脂肪酸缺乏 (EFAD) 风险的担忧.
- 需要长时间的肠外营养的儿科患者特别容易受到营养失衡的影响.
研究的目的:
- 评估接受80%橄油/20% SO ILE与100% SO ILE相比的儿科患者EFAD的风险.
- 评估儿童用ILE中降低的SO含量的安全性和耐受性.
主要方法:
- 一项随机,双盲,受控的多中心研究,涉及101名儿科患者,包括早产婴儿.
- 主要结果:EFAD的发病率,通过血脂肪酸 (FA) 概况和遗传多态度进行评估.
- 分析包括极端阿拉基酸值和三烯:四烯 (T:T) 比率.
主要成果:
- 在80%橄油/20% SO (OO/SO) 或100% SO组中没有观察到EFAD病例.
- 酸在两组中都增加,在OO/SO组的增加较小.
- 阿拉基酸保持稳定;蜂蜜酸的变化相反,导致类似的T:T比率. 在患有极端阿拉基酸值的患者中,发现了遗传多态性.
结论:
- 80% OO/20% SO ILE在儿科患者中是安全的和耐受的,不会增加EFAD风险.
- EFAD评估应纳入完整的FA概况和遗传多态,而不仅仅是T:T比率.

Lipids: Dietary Sources and Requirements
1.1K
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

Lipid-derived Compounds in the Human Body
5.4K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Lipid Absorption
868
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

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

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...

Blood Studies for Cardiovascular System III: Serum Lipid Profile
303
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Structure of Lipids
91.8K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...
