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...

Although the effects of antenatal corticosteroid therapy in clinical improvement and pulmonary maturation in preterm have been described, little is known on premature newborn puppies. This study aimed to evaluate the effect of maternal administration of a single dose of prenatal betamethasone on lung function of preterm newborn puppies in the first hours of life, especially from the clinical point of view and acid-base balance. A prospective study was conducted involving 21 puppies allocated into three experimental groups: Term Group (63 days post-ovulation), Preterm-Treated Group (57 days post-ovulation and maternal administration of a single dose of 0...

BACKGROUND: Soluble fms-like tyrosine kinase receptor-1 (sFlt-1)/placental growth factor (PlGF) ratio has been studied extensively as a predictive marker for pre-eclampsia. However, its usefulness for predicting neonatal outcomes remains unknown. This study aimed to evaluate the association of sFlt-1/PlGF ratio with pregnancy outcomes, neonatal morbidities and short-term postnatal growth patterns in pregnant women and their babies. METHODS: sFlt-1 and PlGF were measured in women with fetal intrauterine growth retardation (IUGR) or pre-eclampsia during gestational age (GA) of 16-36 weeks...

Nigeria's under-five mortality rate is the eighth highest in the world. Identifying the causes of under-five deaths is crucial to achieving Sustainable Development Goal 3 by 2030 and improving child survival. National and international bodies collaborated in this study to provide the first ever direct estimates of the causes of under-five mortality in Nigeria. Verbal autopsy interviews were conducted of a representative sample of 986 neonatal and 2,268 1-59 month old deaths from 2008 to 2013 identified by the 2013 Nigeria Demographic and Health Survey...

BACKGROUND: Neonatal sepsis remains one of the leading causes of morbidity and mortality both among term and preterm infants. Advances in neonatal care improved survival and reduced complications in preterm infants. Chemokines are chemotactic cytokines that give directional guidance for leukocyte migration during inflammatory process. The chemokine CXCL12 and its receptor CXCR4 are now known to play an important role in inflammatory states. However, its value as a biomarker in neonatal sepsis is unclear...

BACKGROUND: Preterm birth is a major paediatric challenge difficult to prevent and with major adverse outcomes. Prenatal stress plays an important role on preterm birth; however, there are few stress-related models to predict preterm birth in women with Threatened Preterm Labor (TPL). OBJECTIVE: The aim of this work is to study the influence of stress biomarkers on time until birth in TPL women. METHODS: Eligible participants were pregnant women between 24 and 31 gestational weeks admitted to the hospital with TPL diagnosis (n=166)...

A placental surface cyst is a cystic mass arising from the surface of the placenta. It is seldom complicated by intracystic hemorrhaging and the clinical importance of this kind of case is unclear. Therefore, we present a case of a placental surface cyst with intracystic hemorrhaging. A 29-year-old multiparous woman was diagnosed with multiple placental surface cysts with threatened preterm birth and fetal growth restriction on ultrasonography at 26 gestational weeks (GW). At 31 GW, the hemorrhage was identified inside the cyst...

Extreme prematurity is a major cause of neonatal mortality and morbidity, and remains an unsolved clinical challenge. The development of an artificial womb, an extrauterine system recreating the intrauterine environment, would support ongoing growth and organ maturation of the extreme preterm fetus and would have the potential to substantially improve survival and reduce morbidity. Previous efforts toward the development of such a system have demonstrated the ability to maintain the isolated fetus for short periods of support, but have failed to achieve the long-term stability required for clinical application...

Antenatal steroid treatment to enhance fetal lung maturity and surfactant treatment to prevent or treat respiratory distress syndrome have been major advances in perinatal medicine in the past 40 years contributing to improved outcomes for preterm infants. Use of postnatal steroids to prevent or treat chronic lung disease in preterm infants has been less successful and associated with adverse neurodevelopmental outcomes. Although early (in the first week of life) postnatal steroid treatment facilitates earlier extubation and reduces the risk of chronic lung disease, it is associated with adverse effects, such as hyperglycemia, hypertension, gastrointestinal bleeding and perforation, hypertrophic cardiomyopathy, growth failure, and cerebral palsy, and cannot be recommended...

In the last 4 decades, advances in neonatology have led to a significant increase in the survival of preterm infants. One of the biggest advances was the introduction of surfactant replacement therapy for the treatment of respiratory distress syndrome. This is the main cause of respiratory insufficiency in preterm infants and is one of the major causes of perinatal morbidity and mortality. Surfactant replacement therapy is already a well-investigated and established therapy in neonatology. However, surfactant replacement therapy has progressed and been refined over recent decades, especially with the increasing care for preterm infants born before 26 weeks' gestational age and the recent clinical focus on avoiding mechanical ventilation...

INTRODUCTION: To evaluate the largest vertical pocket (LVP) of amniotic fluid as a time-dependent factor to predict perinatal mortality in women with early preterm premature rupture of membranes (EPPROM). MATERIAL AND METHODS: Observational cohort study of singleton pregnancies with EPPROM <24 weeks. Termination of pregnancy (TOP) was considered if the LVP was <2 cm at 7 days. The maternal and neonatal characteristics of ongoing pregnancies were recorded. Prediction of perinatal mortality was estimated based on the influence of the LVP as a time-dependent factor after adjustment for maternal age, prior invasive procedure, and gestational age at EPPROM...

Large randomized controlled trials (RCTs) in preterm infants offer unique opportunities for mechanistic evaluation of the risk factors leading to serious diseases, as well as the actions of interventions designed to prevent them. Necrotizing enterocolitis (NEC) a serious inflammatory gut condition and late-onset sepsis (LOS) are common feeding and nutrition-related problems that may cause death or serious long-term morbidity and are key outcomes in two current UK National Institutes for Health Research (NIHR) trials...

Selective intrauterine growth restriction (sIUGR) affects 10-15% of all monochorionic pregnancies. Early severe forms are associated with intrauterine demise or neurological adverse outcome for both twins. The characteristics of umbilical artery (UA) Doppler in the IUGR fetus determine three clinical types: (I) normal UA Doppler and associated with good prognosis; (II) persistently absent/reverse UA end-diastolic flow and associated with early deterioration of the IUGR twin and very preterm delivery; (III) intermittently absent/reverse end-diastolic flow in the UA, and associated with unexpected fetal demise or neurological injury in one or both twins...

A pregnancy complicated with rheumatologic diseases can have various influences on the fetus and/or neonate. Maternal systemic lupus erythematosus (SLE) may cause preterm and/or small for gestational age (SGA) delivery and neonatal lupus (NL). Some neonates with NL have congenital heart block (CHB) with increased morbidity and mortality, even requiring pacemakers. Antiphospholipid syndrome may occur with SLE and affect fetal and/or neonatal outcomes. Pregnancy involving primary Sjögren's syndrome (pSS) tends to result in preterm delivery and low birthweight infants...

BACKGROUND: Preterm birth (PTB) is the leading cause of neonatal morbidity and mortality in non-anomalous neonates in the US. Women with a previous early spontaneous PTB are at highest risk for recurrence. Weekly intramuscular 17-alpha hydroxyprogesterone caproate (17-OHPC) reduces the risk of recurrent prematurity. Though current guidelines recommend 17-OHPC initiation between 16-20 weeks', in clinical practice, 17-OHPC is started across a spectrum of gestational ages. OBJECTIVE: To examine the relationship between the gestational age at 17-OHPC initiation and recurrent PTB among women a prior spontaneous PTB 16-28 weeks' gestation...

Many extremely preterm infants (born before 28 gestational weeks [GWs]) develop cognitive impairment in later life, although the underlying pathogenesis is not yet completely understood. Our examinations of the developing human neocortex confirmed that neuronal migration continues beyond 23 GWs, the gestational week at which extremely preterm infants have live births. We observed larger numbers of ectopic neurons in the white matter of the neocortex in human extremely preterm infants with brain injury and hypothesized that altered neuronal migration may be associated with cognitive impairment in later life...

BACKGROUND: Congenital heart defects (CHD) and preterm birth (PTB) are major causes of infant mortality. However, limited data exist on risk of mortality associated with PTB for newborns with CHD. Our objective was to assess impact of PTB on risk of infant mortality for newborns with CHD, while taking into account the role of associated anomalies and other potentially confounding factors. METHODS: We used data on 2172 live births from a prospective population-based cohort study of CHD (the EPICARD Study) and compared neonatal, post-neonatal and overall infant mortality for infants born at <32, 32-34 and 35-36 weeks vs...
