Association of increased maternal ferritin levels with gestational diabetes and intra-uterine growth retardation.

AIM: The objectives of the present study were to determine whether or not increased serum ferritin in women with premature labour is associated with gestational diabetes mellitus (GDM) and intra-uterine growth retardation (IUGR) and, if so, whether or not such increased levels reflect excess maternal iron stores, and have an effect on neonatal iron status and outcome. METHODS: This prospective, single-hospital, observational study involved 63 mothers and their 90 preterm neonates. Full blood counts as well as serum ferritin, soluble transferrin receptor (sTfR) and erythropoietin concentrations were compared across the three study groups based on maternal ferritin levels at the time of delivery. Perinatal history, neonatal morbidity and early outcomes were also assessed. RESULTS: High maternal ferritin levels were significantly associated with higher rates of GDM and IUGR. However, there was no correlation between maternal ferritin and sTfR levels or between maternal and neonatal iron status. CONCLUSION: Elevated maternal ferritin is not a reflection of excess iron stores, but is related to an increased risk of GDM or IUGR. Also, maternal ferritin levels are not associated with either neonatal iron status or neonatal outcomes. Copyright (c) 2009 Elsevier Masson SAS. All rights reserved

The influence of extrauterine life on the aEEG maturation in normal preterm infants

Objective: To study, the maturational changes of the amplitude-integrated electroencephalogram (aEEG) in preterm infants without neurological disorders and especially the influence of the duration of extrauterine life, over this process. Methods: 96 preterm infants, 25-34 weeks' gestational age (CA) at birth, clinically stable and without ultrasonographic evidence of neurological abnormalities, were studied. The aEEG recordings were obtained within 72 h of life and then weekly until discharge. Four aspects of each tracing (continuity. sleep-wake cycling, bandwidth, and lower border), were evaluated by visual analysis, applying pre-established criteria. Results: We analysed 624 aEEG recordings at postmenstrual age (PMA) of 25-42 weeks. With advanced CA the aEEG becomes more continuous (p: 0.022), it displays definite sleep-wake cycles (p: 0.011), and its bandwidth acquires the mature pattern (p: 0.012). A positive significant interaction of CA and PMA in the evolution of aEEG was found regarding continuity (p: 0.002), sleep-wake cycling (p: 0.002), and bandwidth (p: 0.02). Conclusion: The evolution of the aEEG tracing depends on both CA and PMA. The older the infants at birth the more mature the aEEG pattern. At the same PMA, preterm infants of lower CA display an advanced maturation of the aEEG comparing with others of higher GA. (c) 2009 Elsevier Ireland Ltd. All rights reserved

Establishing nationally representative central line-associated bloodstream infection surveillance data for paediatric patients in Greece

Background: Healthcare-associated infections (HCAIs) are associated with increased morbidity and mortality and with excess costs. Central line-associated bloodstream infections (CLABSIs) are the most common HCAIs in neonates and children. Aim: To establish national benchmark data for rates of CLABSI in neonatal and paediatric intensive care units (NICUs and PICUs) and paediatric oncology units (ONCs). Methods: Active surveillance for CLABSI was conducted from June 2016 to February 2017. A collaborative of 14 NICUs, four PICUs, and six ONCs participated in the programme. Surveillance definitions of central line (CL), central line utilization (CLU) ratio, CLABSI event, and CLABSI rate were based on the Centers for Disease Control and Prevention's 2014 National Healthcare Safety Network criteria. Medical records were assessed daily for calculating CL-days, patient-days, and susceptibility of isolated organisms. Findings: A total of 111 CLABSI episodes were recorded. The overall mean CLABSI rate was 4.41 infections per 1000 CL-days, and the CLU ratio was 0.31. CLABSI rates were 6.02 in NICUs, 6.09 in PICUs, and 2.78 per 1000 CL-days in ONCs. A total of 123 pathogens were isolated. The most common pathogens were Enterobacteriaceae (36%), followed by Gram-positive cocci (29%), non-fermenting Gram-negative bacteria (16%), and fungi (16%). Overall, 37% of Gram-negative pathogens were resistant to third-generation cephalosporins and 37% to carbapenems. Conclusion: Nationally representative CLABSI rates were determined for paediatric patients. These data could be used to benchmark and serve as baseline data for the design and evaluation of infection control and antimicrobial stewardship interventions. © 2018 The Healthcare Infection Societ

Impact of perinatal factors on continuous early monitoring of brain electrocortical activity in very preterm newborns by amplitude-integrated EEG.

Background:Amplitude-integrated electroencephalogram (aEEG) is increasingly used for neuromonitoring in preterms. We aimed to quantify the effects of gestational age (GA), postnatal age (PNA), and other perinatal factors on the development of aEEG early after birth in very preterm newborns with normal cerebral ultrasounds.Methods:Continuous aEEG was prospectively performed in 96 newborns (mean GA: 29.5 (range: 24.4-31.9) wk, birth weight 1,260 (580-2,120) g) during the first 96 h of life. aEEG tracings were qualitatively (maturity scores) and quantitatively (amplitudes) evaluated using preestablished criteria.Results:A significant increase in all aEEG measures was observed between day 1 and day 4 and for increasing GA (P < 0.001). The effect of PNA on aEEG development was 6.4- to 11.3-fold higher than that of GA. In multivariate regression, GA and PNA were associated with increased qualitative and quantitative aEEG measures, whereas small-for-GA status was independently associated with increased maximum aEEG amplitude (P = 0.003). Morphine administration negatively affected all aEEG measures (P < .05), and caffeine administration negatively affected qualitative aEEG measures (P = 0.02).Conclusion:During the first few days after birth, aEEG activity in very preterm infants significantly develops and is strongly subjected to the effect of PNA. Perinatal factors may alter the early aEEG tracing and interfere with its interpretation
