Comparisons of proteomic profiles of whey protein between donor human milk collected earlier than 3 months and 6 months after delivery.

Background And Objectives: Human milk has nutritional, protective, and developmental advantages for premature infants. However, proteomic information of low abundant protein of donor milk is insufficient. The purpose of this study is to analyze and compare the proteome of low abundant protein of donor milk obtained at different postpartum ages other than the colostrum.

Is procalcitonin to C-reactive protein ratio useful for the detection of late onset neonatal sepsis?

Procalcitonin (PCT) has been reported as a sensitive marker for neonatal bacterial infections. Recently, small numbers of studies reported usefulness of PCT/C-reactive protein (CRP) ratio in detection of infectious conditions in adults. Thus, we conducted this study to evaluate PCT/CRP ratio in late onset neonatal sepsis.

Do gender and birth height of infant affect calorie of human milk? An association study between human milk macronutrient and various birth factors.

Objective: The purpose of this study is to analyze the macronutrient of human milk (HM) and to find out the various maternal-infantile factors that can affect HM composition.

Methods: 478 HM samples were collected from healthy and exclusively breast-feeding mothers who delivered healthy term neonates within 3 months. Macronutrient of the samples was analyzed and the birth data were collected.

Reference Intervals of Serum Procalcitonin Are Affected by Postnatal Age in Very Low Birth Weight Infants during the First 60 Days after Birth.

Background: Procalcitonin (PCT) may be a more sensitive marker for neonatal bacterial infections than C-reactive protein (CRP). However, the reference intervals of serum PCT were not sufficiently studied in neonates older than 1 week of age, especially for very low birth weight infants.

Objectives: This study investigated the reference level of serum PCT for neonates according to gestational age (GA) and postnatal age (PNA).
