Quantification of macronutrients in human milk after premature birth depending on the gestational and postnatal age of infant

(jednostránkový souhrn) v angličtině Growth restriction of premature newborns is a serious complication for the further development of the infant. It is not yet definitely clear to which extent it is associated with the low content of certain macronutrients of human milk. Maternal characteristics may be connected with human milk macronutrients, but no definite conclusions have been made to date. This study aimed to evaluate the content of macronutrients in human milk samples after preterm delivery during the first 9 weeks of lactation and determine the relationship of maternal-associated factors on the content of macronutrients in human milk after preterm delivery. Milk samples were collected from mothers after premature birth between 24+0-35+6 weeks. Macronutrients and energy content were analyzed by mid-infrared transmission spectroscopy. A total 1917 human milk samples from were analyzed. Median of protein content decreased from 1.6 g/dL in group A and 1.5 g/dL in group B in the first week of life, to 1.1 g/dL in both groups at the end of week 3, and then remained stable up to week 9. Content of carbohydrates and fat was stable during the whole observation, with interindividual differences. Similarly to colostrum, higher protein content and lower carbohydrates content were observed in...
Determinants of premature atherosclerosis in children with end-stage renal disease

Children with chronic renal failure are at extremely high risk of premature cardiovascular disease. In our work, we have shown that the measurement of carotis intima- media thickness (CIMT) with high resolution ultrasound is a suitable method for the diagnosis of early atherosclerotic changes especially in younger children. In contrast, flow mediated dilatation (FMD) according to our experience is not very suitable method for investigations in pediatrics because of its high variability. In our group of patients we did not find correlation of preclinical atherosclerosis measured by CIMT with any of the traditional cardiovascular risk factors (hypertension, dyslipidemia, overweight expressed as body mass index). In contrast, a significant negative correlation was found in the ESRD patients between the CIMT and serum bilirubin and albumin. On the one hand, these findings could indicate an impaired defending mechanisms against oxidative stress, which are considered one of the key factors in the development of atherosclerotic process, on the other hand they indicated an important role played by nutritional status in children with ESRD. In addition, we found strong evidence for significant correlations between CIMT and proteinuria as another discussed cardiovascular risk factor in boys, but not in girls. To our...
