OBJECTIVES: To describe the frequency and findings of cranial imaging in moderately preterm infants (born at 290/7 -336/7 weeks of gestation) across centers, and to examine the association between abnormal imaging and clinical characteristics. STUDY DESIGN: We used data from the Neonatal Research Network Moderately Preterm Registry, including the most severe early (≤28 days) and late (>28 days) cranial imaging. Stepwise logistic regression and CART analysis were performed after adjustment for gestational age, antenatal steroid use, and center...

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials-the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial-have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns...

Programmed death-1 (PD-1) receptor system represents a part of recently reported immunoregulatory pathway. PD-1 is an immune checkpoint molecule, which plays an important role in downregulating the immune system proinflammatory activity. Until recently, PD-1 expression was not established on immune cells of the preterm infants. The study objectives were to confirm expression of the PD-1 receptors on the monocytes isolated from very low birth weight newborns (VLBW), and to analyze their expression during the first week of life and late-onset sepsis...

BackgroundBeing aware of the impact of low birth weight on late-onset hypertension, our aim was to describe systolic blood pressure (sBP) and renal function in 3-5-year-old preterm-born children and to determine which perinatal factors or childhood factors were associated with an altered renal function at 5 years in these children.MethodsThis was a prospective longitudinal cohort study of children born at 27-31 weeks of gestation and included at birth and examined at 3, 4, and 5 years of age. The primary outcome was renal function at 5 years: BP, estimated glomerular filtration rate, and albuminuria...

BACKGROUND: Prematurity is still a major problem for health care services throughout the world. Before the late 1980s, respiratory distress syndrome (RDS) was the primary cause of morbidity and mortality in preterm new-borns. Frequency of RDS and ensuing mortality in infants treated with antenatal steroid is less than those delivered without this therapy. Many pregnant females deliver before term or 37 weeks, hence may be advised this prophylactic therapy without creating significant maternal or foetal side effects...

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...

Eugene M Dempsey
The management of preterm infants with low blood pressure soon after birth remains unresolved. The definition of what constitutes low blood pressure is uncertain. At birth, mean blood pressure appears to be gestation specific and increases in the first few days of life. Antenatal steroids, delayed cord clamping, and the avoidance of mechanical ventilation are all associated with higher mean blood pressure and less hypotension after birth. Rates of hypotension of 15-50% have been reported in various studies of extremely preterm infants...

BACKGROUND: In 2016, guidance statements were issued by the Society for Maternal-Fetal Medicine and the American Congress of Obstetricians and Gynecologists about extending antenatal steroid use to selected late preterm singleton pregnancies. OBJECTIVE: We sought to review antenatal steroid use prior to the 2016 guidance statements and assess the potential impact of these. STUDY DESIGN: This cohort study used chart-abstracted data from singleton deliveries from Jan...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...

BACKGROUND: Postnatal adaptation requires liquid clearance and lung aeration. However, their relative contribution to the expansion of functional residual capacity (FRC) has not been fully investigated. We studied evolution of lung liquid removal and lung aeration after birth in preterm lambs. METHODS: Lung liquid content and lung volume were assessed at birth and every 30 min over 2 h using magnetic resonance imaging (MRI) in three groups of lambs delivered by cesarean: preterm, late preterm, and late preterm with antenatal steroids...

Baiba Steinbrekera, Robert Roghair
The risk of hypertension is increased by intrauterine growth restriction (IUGR) and preterm birth. In the search for modifiable etiologies for this life-threatening cardiovascular morbidity, a number of pathways have been investigated, including excessive glucocorticoid exposure, nutritional deficiency and aberration in sex hormone levels. As a neurotrophic hormone that is intimately involved in the cardiovascular regulation and whose levels are influenced by glucocorticoids, nutritional status and sex hormones, leptin has emerged as a putative etiologic and thus a therapeutic agent...

AIM: All women delivering a preterm infant should receive antenatal corticosteroid prophylaxis, but many miss this opportunity. We determined the risk factors associated with missed prophylaxis in a geographically defined area of Italy. METHODS: We prospectively studied all mothers who delivered babies between 24 and 31 completed weeks of gestation, from 2009 to 2013, in all maternity units in Tuscany. RESULTS: Of 1232 mothers, 186 (15.1%) did not receive prophylaxis...
