概括
含高sn-2棕酸的部分化配方 (HPF) 可能减少早产婴儿中与乙素相关的炎症. 这项研究表明,HPF具有抑制炎症的潜力,而不会影响住院或死性肠球炎 (NEC) 发病率.
科学领域:
- 新生儿免疫学 新生儿免疫学
- 儿科胃肠病学 儿科胃肠病学
- 婴儿营养 婴儿营养
背景情况:
- 过早出生的婴儿具有不成熟的免疫系统,增加了对2型炎症的易感性,其特点是以氨基酸细胞的招募,这可能会恶化肠道和呼吸道炎症.
- 哺乳通过sn-2棕酸和免疫调节因子提供抗炎益处,但配方养通常是临床上必要的.
- 部分化配方 (HPF) 含高sn-2棕酸被假设通过降低蛋白质免疫性来减轻与乙氨基酸相关的炎症,尽管支持证据有限.
研究的目的:
- 为了评估高sn-2棕酸部分化配方 (HPF) 对早产婴儿的乙酸细胞计数和相关炎症标志物的影响.
- 评估HPF与标准早产配方 (SPF) 相比,HPF的安全性和有效性,包括住院时间和死性肠球炎 (NEC) 发病率.
主要方法:
- 对PRIOR随机对照试验 (RCT) 的二次分析,涉及90名早产婴儿 (<34周妊娠年龄或<2000克出生体重).
- 婴儿被随机分配给接受HPF (n=45) 或SPF (n=45).
- 乙氨基酸细胞数量,住院时间和NEC发病率是主要和次要结局,使用通用添加模型进行分析.
主要成果:
- 80名婴儿完成了住院阶段;这些组在基线特征上相似.
- 在长期暴露 (>25天,p=0.053) 后,观察到HPF的趋势是降低乙氨基酸百分比,这表明潜在的炎症抑制.
- 在住院时间 (HPF:30天与SPF:27天) 或NEC发病率 (2.4%与2.4%) 中没有发现显著差异.
结论:
- HPF在潜在地减少早产婴儿中以氨基酸为媒介的炎症方面显示出希望.
- 在这个队列中,HPF没有显著影响住院时间或NEC发病率.
- 需要进一步的研究来探索HPF等优化过早配方的长期免疫益处.

Molecular Compounds: Formulas and Nomenclature
55.6K
Molecular compounds or covalent compounds result when atoms share electrons to form covalent bonds. Since there is no electron transfer, molecular compounds do not contain ions; instead, they consist of discrete, neutral molecules.

Chemical Formulas
61.2K
A chemical formula presents information about the proportions of atoms constituting a particular chemical compound or molecule, mainly using symbols of elements and numbers. At times other symbols, such as dashes, parentheses, brackets, commas, plus, and minus signs, are also used. A chemical formula can be one of three types – molecular, empirical, and structural.

Ionic Compounds: Formulas and Nomenclature
86.9K
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.

Experimental Determination of Chemical Formula
47.0K
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of its constituent elements is often the first step in determining the formula experimentally.

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...
