背景情况:

呼吸应急综合征 (RDS) 是早产婴儿疾病的重要原因之一.
预测需要表面活性剂治疗对于管理非常早产新生儿的RDS至关重要.

研究的目的:

调查胃液代谢分析的潜力,以预测RDS的非常早产婴儿的表面活性剂需求.
为了确定特定的胃液代谢物和预测表面活性剂的临床因素.

主要方法:

一项病例控制研究涉及43名患有需要表面活性剂的RDS的婴儿和30名不需要表面活性剂的对照.
在胃液样本上使用气色谱-质谱的非向代谢分析.
统计分析包括单变量和多变量模型来评估代谢物和临床参数的预测值.

主要成果:

在两组之间发现胃液代谢物 (L-proline,L-glycine,L-threonine,乙-L-serine) 的显著差异.
单独的代谢物和单独的临床因素都无法准确预测表面活性剂的需求.
结合乙-L-氨酸和分娩室输管的多变量模型实现了0.76的AUC,表明预测准确度有所提高.

Breathing

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
