Gestational diabetes mellitus (GDM) is associated with excessive oxidative stress which may affect placental vascular function. Cholesterol homeostasis is crucial for maintaining fetoplacental endothelial function. We aimed to investigate whether and how GDM affects cholesterol metabolism in human fetoplacental endothelial cells (HPEC). HPEC were isolated from fetal term placental arterial vessels of GDM or control subjects. Cellular reactive oxygen species (ROS) were detected by H2 DCFDA fluorescent dye. Oxysterols were quantified by gas chromatography-mass spectrometry analysis...

Properties of the local internal environment of the adult brain are tightly controlled providing a stable milieu essential for its normal function. The mechanisms involved in this complex control are structural, molecular and physiological (influx and efflux transporters) frequently referred to as the "blood-brain barrier". These mechanisms include regulation of ion levels in brain interstitial fluid essential for normal neuronal function, supply of nutrients, removal of metabolic products and prevention of entry or elimination of toxic agents...

A 29-year-old woman presented with influenza A ARDS at 23+0 weeks of gestation. Mechanical ventilation failed and VV-ECMO was started in a non-ECMO hospital. Transportation was performed on ECMO. Within 5 days ECMO weaning was successful. Fetal condition was stable, and decision to continue pregnancy was taken. However, second VV-ECMO was needed due to ventilator-associated pneumonia. At 25+6 weeks, the patient spontaneously delivered a neonate vaginally. Patient's condition improved, and ECMO could be removed 10 days postpartum...

OBJECTIVE: To evaluate whether completion of vital signs assessments in pediatric transports by emergency medical services (EMS) differs by patient age. STUDY DESIGN: We reviewed records by 20 agencies in a regional EMS system in Southwestern Pennsylvania between April 1, 2013 and December 31, 2016. We abstracted demographics, vital signs (systolic blood pressure, heart rate, respiratory rate), clinical, and transport characteristics. We categorized age as neonates (≤30 days), infants (1 month to <1 year), toddler (1 to <2 years), early childhood (2 to <6 years), middle childhood (6 to <12 years), adolescent (12 to <18 years), and adult (≥18 years)...

REVIEW
Andrew D Clouston
The inherited diseases causing conjugated hyperbilirubinemia are diverse, with variability in clinical severity, histologic appearance, and time of onset. The liver biopsy appearances can also vary depending on whether the initial presentation is in the neonatal period or later. Although many of the disorders have specific histologic features in fully developed and classic cases, biopsies taken early in the disease course may be nonspecific, showing either cholestatic hepatitis or an obstructive pattern of injury requiring close correlation with the laboratory and clinical findings to reach the correct diagnosis...

We studied the pregnant women, who requested a '108' ambulance in two Indian states (Andhra Pradesh (AP) and Himachal Pradesh (HP)). We conducted a cross-sectional telephone survey to study the characteristics and outcomes of those who (1) were transported using '108' ambulance, (2) were sent '108' ambulance but did not use it and (3) were not assigned a '108' ambulance. We conducted interviews within 24 hours of clients' call and followed them up at 48 hours, on the 7th and 28th day. 90% of pregnant women callers in AP and only 16% in HP were from poorer socioeconomic circumstances...

OBJECTIVE: Specialty pediatric transport teams are widely used for pediatric interfacility transport in the United States, with little industry consensus on optimal team configuration. The aim of this study is to assess the quality of the nurse/paramedic specialty team configuration as indirectly measured by the rate of adverse events in these transports. METHODS: Retrospective analysis of pediatric transport data from a hospital-based dedicated pediatric/neonatal transport team was conducted for patients transported in 2016...

Introduction: Neuroprotection with therapeutic hypothermia (TH) is standard of care for neonatal encephalopathy (NE) and decreases death and neurodevelopmental disability. TH initiated shortly after birth insult results in greater neuroprotection compared with delayed initiation. Methods: Quality improvement methodology was used to improve temperature control during transport to a level IV neonatal intensive care unit. We included neonates with NE transported to a single institution for TH from 2010 to 2016...

Homozygous or compound heterozygous for frameshift or nonsense mutations in the ATP-binding cassette transporter A3 (ABCA3) is associated with neonatal respiratory failure and death within the first year of life without lung transplantation. We report the case of a newborn baby girl who developed severe respiratory distress soon after birth. She was diagnosed with compound heterozygous frameshift mutation of the ABCA3 gene. Despite extensive treatment (intravenous corticosteroids pulse therapy, oral corticosteroids, azithromycin, and hydroxychloroquine), she developed chronic respiratory failure...

OBJECTIVES: MR imaging of neonates is difficult for many reasons and a major factor is safe transport to the MR facilities. In this article we describe the use of a small, investigational 3-T MR customised for brain imaging and sited on a neonatal unit of a tertiary centre in the UK, which is in contrast to a 300-m journey to the whole-body MR scanner used at present for clinical cases. METHODS: We describe our methods for preparing babies for safe transport and scanning on an investigational 3-T MR scanner on a neonatal unit and the development of appropriate MR sequences...

The heart of a newborn mouse has an exceptional capacity to regenerate from myocardial injury that is lost within the first week of its life. In order to elucidate the molecular mechanisms taking place in the mouse heart during this critical period we applied an untargeted combinatory multiomics approach using large-scale mass spectrometry-based quantitative proteomics, metabolomics and mRNA sequencing on hearts from 1-day-old and 7-day-old mice. As a result, we quantified 1.937 proteins (366 differentially expressed), 612 metabolites (263 differentially regulated) and revealed 2...

BACKGROUND: Transportation interventions seek to decrease delay in reaching a health facility for emergency obstetric care and are, thus, believed to contribute to reductions in such adverse pregnancy and childbirth outcomes as maternal deaths, stillbirths, and neonatal mortality in low- and middle-income countries (LMICs). However, there is limited empirical evidence to support this hypothesis. The objective of the proposed review is to summarize and critically appraise evidence regarding the effect of emergency transportation interventions on outcomes of labor and delivery in LMICs...

Hyperbilirubinemia is so common in newborns as to be termed physiological. The most common bacteria involved in early-onset neonatal sepsis are Streptococcus agalactiae, commonly called Group B Streptococcus (GBS). Whilst previous studies show bilirubin has antioxidant properties and is beneficial in endotoxic shock, little thought has been given to whether bilirubin might have antibacterial properties. In this study, we performed a transcriptomic and proteomic assessment of GBS cultured in the presence/absence of bilirubin...

Zinc transporter 3 (ZnT3)-dependent "zincergic" vesicular zinc accounts for approximately 20% of the total zinc content of the mammalian telencephalon. Elevated hippocampal ZnT3 expression is acknowledged to be associated with mossy fiber sprouting and cognitive deficits. However, no studies have compared the long-term neurobehavioral phenotype with the expression of ZnT3 in the cerebral cortex following status epilepticus (SE). The aim of this study was to investigate changes in the long-term neurobehavioral phenotype as well as the expression of ZnT3 and calcium homeostasis-related CB-D28k in the cerebral cortex of rats subjected to neonatal SE and to determine the effects of leptin treatment immediately after neonatal SE...

RATIONALE: Ontogenetic differences in the behavioral responsiveness to cocaine have often been attributed to the maturation of dopaminergic elements (e.g., dopamine transporters, D2High receptors, receptor coupling, etc.). OBJECTIVE: The purpose of this study was to determine whether ontogenetic changes in cocaine pharmacokinetics might contribute to age-dependent differences in behavioral responsiveness. METHODS: Male and female neonatal (PD 5), preweanling (PD 10 and PD 20), and adult (PD 70) rats were injected (IP) with cocaine or saline and various behaviors (e...

Cyclic nucleotides are universally used as secondary messengers to control cellular physiology. Among these signalling molecules, cyclic di-adenosine monophosphate (c-di-AMP) is a specific bacterial second messenger recognized by host cells during infections and its synthesis is assumed to be necessary for bacterial growth by controlling a conserved and essential cellular function. In this study, we sought to identify the main c-di-AMP dependent pathway in Streptococcus agalactiae, the etiological agent of neonatal septicaemia and meningitis...

INTRODUCTION: Breast milk expression with a breast pump increases the risk of contaminating milk with pathogenic bacteria; how to decontaminate breast pumps is controversial. The aim of this study was to investigate maternal adherence to updated French guidance on the breast milk collection process, including breast pump decontamination, and to identify potential sources of increased bacterial counts in breast milk in order to improve prevention messages to mothers. METHODS: Descriptive prospective study conducted between November 2015 and April 2016 in a French tertiary perinatal center...

The incidence of perinatal opioid use and neonatal withdrawal continues to rise rapidly in the face of the growing opioid addiction epidemic in the United States, with rural areas more severely affected. Despite decades of research and development of practice guidelines, maternal and neonatal outcomes have not improved substantially. This focused ethnography sought to understand the experience of accessing care necessary for substance use disorder recovery, pregnancy, and parenting. Personal accounts of 13 rural women, supplemented by participant observation and media artifacts, uncovered three domains with underlying themes: challenges of getting treatment and care (service availability, distance/geographic location, transportation, provider collaboration/coordination, physical and emotional safety), opportunities to bond (proximity, information), and importance of relationships (respect, empathy, familiarity, inclusion, interactions with care providers)...

Secondary envelopment of human cytomegalovirus (HCMV) occurs through a mechanism that is poorly understood. Many enveloped viruses utilize the endosomal sorting complexes required for transport (ESCRTs) for viral budding and envelopment. Although there are conflicting reports on the role of the ESCRT AAA-ATPase protein VPS4 in an HCMV infection, VPS4 may act in an envelopment role similar to its function during other viral infections. Because VPS4 is normally recruited by the ESCRT-III complex, we hypothesized that ESCRT-III subunits would also be required for HCMV infection...
