INTRODUCTION: Lactate concentration in umbilical cord blood is an important measure of intrapartum anaerobic metabolism. The aim of the study was to compare lactate production of large-for-gestational-age (LGA) fetuses against appropriate-for-gestational-age (AGA) fetuses during hypoxia, in diabetic and non-diabetic mothers. MATERIAL AND METHODS: 17 358 validated paired arterial and venous umbilical cord blood samples taken at birth with a full panel of pH, glucose and lactate were analyzed relative to LGA (n=2789) and AGA (n=14 569)...

OBJECTIVE: Telomeres are specialized nucleoprotein structures located at the ends of chromosomes, which play a crucial role in genomic stability. Telomere shortening has been proposed as a biomarker for the onset of age-related diseases. This study aimed to determine whether restricted or increased intrauterine growth affects leukocyte telomere length (LTL) at birth. MATERIAL AND METHODS: One hundred sixty five (n = 165) full-term neonates participated in the study...

Type 1 diabetes mellitus (T1DM) is still related to altered fetal growth and severe maternal complications. We studied the possible role of placental visfatin/nicotinamide phosphoribosyltransferase (NAMPT) in fetal development in T1DM pregnancies, the possible role of placental visfatin in fetal macrosomia. Sixty five pregnant women with T1DM and singleton pregnancy were qualified into the study. Placental visfatin expression was by analysed by RT-PCR. We demonstrated the lowest expression of placental visfatin in women who delivered neonates with birth weight NBW > 4000 g (0...

We first showed the sex- and gestational age (week)-specific birthweight distributions from primiparous and multiparous mothers. Birthweight percentiles were created by using the Lambda Mu Sigma (LMS) method. We established the birthweight percentiles in Southern China and provide clinicians and researchers with up-to-date population norms of birthweight percentiles. Then we use the data from Birth Certificate System between Jan 1st, 2017 and Oct 31st, 2017, which included 1,245,364 live births to calculate SGA and LGA ratio by these three birthweight references- the new INTERGROWTH-21st standard, China's 2015 research standard and our birthweight percentiles...

BACKGROUND: The World Health Organization (WHO) adopted more stringent diagnostic criteria for GDM in 2013, to improve pregnancy outcomes. However, there is no global consensus on these new diagnostic criteria, because of limited evidence. The objective of the study was to evaluate maternal characteristics and pregnancy outcomes in two cohorts in the Netherlands applying different diagnostic criteria for GDM i.e. WHO-2013 and WHO-1999. METHODS: A multicenter retrospective study involving singleton GDM pregnancies in two regions, between 2011 and 2016...

REVIEW
Sine Berntsen, Anja Pinborg
Increase in success rates with frozen embryo transfer (FET) and reduced risk of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies has lead to a steady rise in FET. Further, FET is associated with lower risk of prematurity and low birth weight in singletons, when compared with fresh transfer. However, there is a growing concern of increased risk of large for gestational (LGA) and/or macrosomic children after FET. Macrosomic/LGA births have a higher risk of cesarean section, fetal hypoxia and stillbirth...
