Objectives: Human milk oligosaccharides (HMOs) are known as important factors in neurologic and immunologic development of neonates. Moreover, freeze-drying seems to be a promising storage method improve the processes human banks. However, effects pasteurization on HMOs were not evaluated yet. The purpose this study is analyze compare profiles collected before after freeze-drying.Methods: Totally nine fresh samples from three healthy mothers at first, second, third week delivery. treated...

The purpose of this study is to analyze the macronutrient human milk (HM) and find out various maternal-infantile factors that can affect HM composition.478 samples were collected from healthy exclusively breast-feeding mothers who delivered term neonates within 3 months. Macronutrient was analyzed birth data collected.In multivariate logistic regression analysis, found be associated with composition changes; higher fat: cesarean section (OR = 2.47, p < 0.001) height 0.84, 0.004); protein:...

Procalcitonin (PCT) has been reported as a sensitive marker for neonatal bacterial infections. Recently, small numbers of studies usefulness PCT/C-reactive protein (CRP) ratio in detection infectious conditions adults. Thus, we conducted this study to evaluate PCT/CRP late onset sepsis. Serum PCT and CRP was measured blood samples from 7 60 days after birth 106 neonates with sepsis 212 controls who were matched gestational age, postnatal weight, gender.

We evaluated the association between macronutrients of human milk (HM), and interactions maternal age body mass index(BMI) in matched conditions.Totally, 80 HM samples were collected from healthy breast-feeding mothers at fourth week lactation. data analyzed. Mothers subgrouped into four groups by (20 s/30 s) BMI (overweight/normal).Two-way ANOVA revealed significant to affect macronutrients; fat, carbohydrate, calories. Moreover, different responses fat calorie found groups.The evaluation...

Diarrheal disease is one of the leading causes worldwide morbidity and mortality, especially in children. It loss body fluid, which may lead to severe dehydration, electrolyte imbalance, shock even death. The mortality rate from acute diarrhea has decreased over last few decades. This decline, developing countries largely due implantation standard World Health Organization-oral rehydration solution (WHO-ORS). However, use ORS been limited by its inability reduce fecal volume or duration....

ABSTRACT Background Ageing often affects biomarker production. Yet, clinical/optimal thresholds to guide clinical decisions do not consider this. Serum albumin decreases with age, but hypoalbuminaemia is defined as serum &amp;lt;4.0 g/dl. This study explores whether age might affect levels and its association mortality in haemodialysis patients. Methods COSMOS (Current Management of Secondary Hyperparathyroidism: a Multicentre Observational Study) prospective, open-cohort, observational...

However, the reference intervals of serum PCT were not sufficiently studied in neonates older 1 week age, especially very low birth weight infants. &lt;b&gt;&lt;i&gt;Objectives:&lt;/i&gt;&lt;/b&gt; This study investigated level according to gestational age (GA) and postnatal (PNA). &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt;...

Purpose: Human milk (HM) proteins are known as important factors in growing and development of neonates. For longer easier storage HM, freeze-drying is suggested one the promising methods for HM banks. However, effects on were not evaluated yet.
