Objective: To access the feasibility of employing metabonomics method in clinical studies. This pilot study intends to introduce nuclear magnetic resonance (NMR)-based metabonomics method to elucidate the metabolism of non-syndromic cleft lip and/or palate (NSCLP) patients.
Methods: High-resolution 1H NMR spectroscopy was performed on blood plasma obtained from NSCLP and non-malformed children. All signal of 1H NMR spectra were recognized within MESTRE-v4.7, and the 1H NMR spectra integration into bins (or buckets) across the spectral regions of bin 0.04 was performed automatically in MESTRE-v4.7. The resulting data matrix was further analyzed, which was performed by SIMCA-P 11.0. The principal component analysis (PCA) was applied to the centered data to explore any clustering behavior of the samples.
Results: The results demonstrated the metabonomic difference in plasma between NSCLP and non-malformed children at least lies in 3-Hydroxybutyrate gamma-CH3, arginine and valine. Arginine excretion appeared to be higher in the non-malformed children population, while NSCLP population excreted higher concentrations of 3-Hydroxybutyrate gamma-CH3 and valine.
Conclusion: The present study clearly demonstrated the great potential of the NMR-based metabonomics approach in elucidating the NSCLP plasma metabolism and the possibility of application in clinic diagnosis and screening.

Objective: To investigate the association between infant mortality and birth weight using estimated fetal weight (EFW) versus birth-weight charts, by gestational age (GA).
Methods: This nationwide population-based study used data from the Finnish Medical Birth Register from 2006 to 2016 on non-malformed singleton live births at 24-41 weeks of gestation (N = 563 630). The outcome was death in the first year of life.
EUROPEAN ASSOCIATION OF PERINATAL MEDICINE (EAPM) Position statement: Use of appropriate terminology for situations related to inadequate fetal oxygenation in labor.

In high-resource countries, adverse perinatal outcomes are currently rare in term, non-malformed fetuses, undergoing labor, but they remain a leading cause of medico-legal dispute. Precise terminology is important to describe situations related to inadequate fetal oxygenation in labor, to ensure appropriate communication between healthcare professionals and adequate transmission of information to parents. This position statement provides consensus definitions from European perinatologists and midwives regarding the most appropriate terminology to describe situations related to inadequate fetal oxygenation in labor: suspected fetal hypoxia, severe newborn acidemia, newborn metabolic acidosis, and hypoxic-ischemic encephalopathy.

Objectives: To investigate the association between maternal early pregnancy body mass index (BMI) and offspring bipolar disorder (BPD).
Methods: We conducted a nationwide cohort study among 1,507,056 non-malformed singleton live-births in Sweden born 1983-2004. Using national registries with prospectively recorded information, we followed participants for a BPD diagnosis from ages 13 to up to 35 years.

Objective: To determine the frequency of genetic syndromes and childhood neurodevelopmental impairment in non-malformed infants born at term with severely low birth weight and no evidence of placental insufficiency.
Methods: This case series was constructed from the data of infants delivered at term between 2013 and 2018 with severely low birth weight, defined as birth weight more than 2.5 SD below the mean, with normal maternal and fetal Doppler (umbilical artery, fetal middle cerebral artery, cerebroplacental ratio and uterine artery) and no maternal hypertensive disorder during pregnancy or fetal structural anomaly on prenatal ultrasound examination.

Background: Most follow-up studies have focused on the long-term consequences of asphyxia at birth on the brain. The aim of this study was to investigate associations between low Apgar score and asphyxia-related complications and subsequent risks of cardiovascular diseases (CVD) in childhood and early adulthood.
Methods: This population-based cohort study included 2,826,424 non-malformed singleton births, born at term (≥37 weeks' gestation) between 1988 and 2018 in Sweden.
