BACKGROUND: Short interpregnancy intervals (SIPI) have been associated with increased risks for adverse neonatal outcomes including preterm delivery and infants small for gestational age (SGA). It has been suggested that mechanistically, adverse neonatal outcomes after SIPI arise due to insufficient recovery of depleted maternal folate levels prior to the second pregnancy. However, empirical data are lacking regarding physiological folate levels in pregnant women with SIPI, and relationships between quantified physiological folate levels and outcomes like SGA...

INTRODUCTION: Placental histologic examination can assist in revealing the mechanism leading to preterm birth. Accumulating evidence suggests an association between intrauterine pathological processes, morbidity and mortality of premature infants, and their long term outcome. Neonatal brain activity is increasingly monitored in neonatal intensive care units by amplitude integrated EEG (aEEG) and indices of background activity and sleep cycling patterns were correlated with long term outcome...

The causative factors of neonatal feeding intolerance are poorly understood, but potentially related to clinical practices such as empiric antibiotic usage. The objective of this study was to evaluate whether early empiric antibiotic exposure negatively affects preterm infants' enteral feeding tolerance. Data from infants without risk factors for sepsis, 500 to 1499 g birth weight and 24 to 34 weeks gestational age were analyzed. The primary outcomes were the empiric antibiotic exposure effects on the infants' total parenteral nutrition usage duration and prevalence of necrotizing enterocolitis (NEC)...

BACKGROUND: Sepsis in the neonatal intensive care unit (NICU) remains one of the most significant causes of morbidity and mortality, especially for preterm newborns. Multi-drug resistant organisms (MDROs) are emerging as important pathogens that cause neonatal sepsis in NICU. Therefore, studying the epidemiology, clinical features, and outcome caused by MDROs vs. non-MDROs, and identifying risk factors that may predispose patients to sepsis by MDROs are important. METHODS: Episodes of blood culture-proven sepsis (age: 0-90 days) in the NICU at our institution from January 2012 to December 2015 were retrospectively reviewed...

BACKGROUND: In the United States, hyperemesis gravidarum is the most common cause of hospitalization during the first half of pregnancy and is second only to preterm labor for hospitalizations in pregnancy overall. In approximately 0.3-3% of pregnancies, hyperemesis gravidarum is prevalent and this percentage varies on account of different diagnostic criteria and ethnic variation in study populations. Despite extensive research in this field, the mechanism of the disease is largely unknown...

BACKGROUND: Docosahexaenoic (C22:6) and arachidonic (C20:4) acids are long-chain polyunsaturated fatty acids (LC-PUFA) essential to neonatal development, being present in the glycerophospholipids of all organs, particularly the brain. In plasma, LC-PUFAs are mainly present in lipoprotein lipids, which are neutral lipids (triglycerides and cholesterol esters) and glycerophospholipids, like choline containing phosphatidylcholine (PC). PURPOSE: To guide future supplementation strategies of C22:6 and C20:4 in combination with choline, we determined the distribution of C20:4 and C22:6 between PC and neutral lipid...

AIM: Very preterm infants are at risk of neonatal hearing loss. However, it is unknown whether infants with a normal neonatal hearing screening result risk sensorineural hearing loss (SNHL) at a later age. METHODS: This cohort study was conducted at the Erasmus Medical University Center Rotterdam, the Netherlands, on 77 very preterm infants born between October 2005 and September 2008. All infants underwent auditory brainstem response audiometry during neonatal hearing screening and at two years of corrected age...

Necrotising enterocolitis (NEC) and sepsis are serious diseases of preterm infants that can result in feeding intolerance, the need for bowel resection, impaired physiological and neurological development, and high mortality rates. Neonatal healthcare improvements have allowed greater survival rates in preterm infants leading to increased numbers at risk of developing NEC and sepsis. Gut bacteria play a role in protection from or propensity to these conditions and have therefore, been studied extensively using targeted 16S rRNA gene sequencing methods...

The short and long-term impact of birth mode on the developing gut microbiome in neonates has potential implications for the health of infants. In term infants, the microbiome immediately following birth across multiple body sites corresponds to birth mode, with increased Bacteroides in vaginally delivered infants. We aimed to determine the impact of birth mode of the preterm gut microbiome over the first 100 days of life and following neonatal intensive care unit (NICU) discharge. In total, 867 stool samples from 46 preterm infants (21 cesarean and 25 vaginal), median gestational age 27 weeks, were sequenced (V4 region 16S rRNA gene, Illumina MiSeq)...

Group B streptococcus (GBS) or Streptococcus agalactiae is a β-hemolytic, Gram-positive bacterium that is a leading cause of neonatal infections. GBS commonly colonizes the lower gastrointestinal and genital tracts and, during pregnancy, neonates are at risk of infection. Although intrapartum antibiotic prophylaxis during labor and delivery has decreased the incidence of early-onset neonatal infection, these measures do not prevent ascending infection that can occur earlier in pregnancy leading to preterm births, stillbirths, or late-onset neonatal infections...

Background Prematurity is a major risk factor for neonatal hearing loss. Recent advancements in magnetic resonance imaging (MRI) have made it possible to evaluate structural details of the membranous labyrinths in premature infants that have heretofore been inaccessible. Objective We compared the prevalence of abnormal cochlear signal intensity in premature and term neonates and evaluated for a potential link with hearing loss. Materials and methods We retrospectively reviewed 148 consecutive MR exams performed in premature (< 37 weeks' gestation) and term neonates performed over a 30-month period...

Preterm birth is the leading cause of neonatal and infant mortality and a substantial portion of neonatal morbidities. The perinatal mortality and morbidity statistics in developing countries are inadequate. In this study, we assessed prevalence and health outcomes of preterm deliveries in tertiary care university hospitals. A retrospective study of hospital records of premature babies born in all the five governmental tertiary care settings during the time interval of 2013-2015 in Shiraz was conducted. Result of this study showed that there was an overall 127...

Genital mycoplasmas, which can be vertically transmitted, have been implicated in preterm birth, neonatal infections, and chronic lung disease of prematurity. Our prior work uncovered 16S rRNA genes belonging to a novel, as-yet-uncultivated mycoplasma (lineage 'Mnola') in the oral cavity of a premature neonate. Here, we characterize the organism's associated community, growth status, metabolic potential, and population diversity. Sequencing of genomic DNA from the infant's saliva yielded 1.44 Gbp of high-quality, non-human read data, from which we recovered three essentially complete (including 'Mnola') and three partial draft genomes (including Trichomonas vaginalis)...
