Obstetric and pediatric growth charts for the detection of late-onset fetal growth restriction and neonatal adverse outcomes.

Objectives: Late-onset fetal growth restriction (FGR) has heterogeneous prenatal and postnatal diagnostic criteria. We compared the prenatal and postnatal diagnosis of late-onset FGR and their ability to predict adverse perinatal outcomes.

Methods: Retrospective cohort study of 5442 consecutive singleton pregnancies that delivered beyond 34 + 0 weeks.

Obstetric and pediatric growth charts for the detection of fetal growth restriction and neonatal adverse outcomes in preterm newborns before 34 weeks of gestation.

Introduction: Identification of fetal growth-restricted (FGR) infants depends on the fetal or newborn charts used to identify them. We aimed to compare the prenatal and postnatal diagnosis of FGR and their ability to predict adverse perinatal outcomes.

Methods: Observational retrospective cohort study of 95 consecutive mother-infant pairs with preterm birth between 24 and 34 weeks (study period: January 2014 to December 2015).

Simultaneous analysis of frequently used licit and illicit psychoactive drugs in breast milk by liquid chromatography tandem mass spectrometry.

A liquid chromatography tandem mass spectrometry (LC-MS-MS) method for the quantification of frequently used licit (caffeine, nicotine and cotinine) and illicit drugs (opiates, cocaine, cannabinoids and amphetamines) in breast milk was developed and fully validated. Chromatography was performed on a reverse-phase column using a gradient of 2mM ammonium acetate, pH 6.6, and methyl alcohol as mobile phase at a flow rate of 0.
