PURPOSE: To evaluate neonatal outcomes in preterm infants with less than 34 weeks after spontaneous labor, preterm premature rupture of membranes (PPROM) or iatrogenic delivery and to clarify whether the mechanism of labor onset is a risk factor for adverse short-term neonatal outcome. METHODS: We performed a retrospective case-control study, which included 266 preterm newborns with less than 34-week gestation, between 2011 and 2015. Neonatal outcomes were compared according to the mechanism of labor onset...

Premature rupture of membranes (PROM) is a common pregnancy complication that frequently results in maternal and perinatal morbidity. The present methods for diagnosing PROM do not satisfy clinical requirements. The present study aimed to examine the proteome profile of amniotic fluid (AF) and maternal plasma, screen unique proteins in AF, and evaluate their diagnostic value for diagnosing PROM. The proteome profiles of AF and maternal plasma were examined via liquid chromatography coupled with tandem mass spectrometry‑based proteomic techniques...

BACKGROUND: Vitamin A (VA) is crucial for lung growth and development. In premature infants, inadequate VA levels are associated with an increased risk of bronchopulmonary dysplasia (BPD). Intramuscular VA supplementation has been shown to decrease the incidence of BPD, but is not widely used in the clinical setting due to concerns about feasibility and pain. We studied VA kinetics, distribution, and the induction of early genetic expression of retinoid homeostatic genes in the lung after endotracheal and intravenous application in a preterm lamb model...

Early prediction of bronchopulmonary dysplasia (BPD) may facilitate tailored management for neonates at risk. We investigated whether easily accessible flow data from a mechanical ventilator can predict BPD in neonates born extremely premature (EP). In a prospective population-based study of EP-born neonates, flow data were obtained from the ventilator during the first 48 h of life. Data were logged for >10 min and then converted to flow-volume loops using custom-made software. Tidal breathing parameters were calculated and averaged from ≥200 breath cycles, and data were compared between those who later developed moderate/severe and no/mild BPD...

Background: Considering all the latest achievements in neonatal respiratory care, bronchopulmonary dysplasia (BPD) is still among the most prevalent morbidity causes in premature infants. Involvement in this process results in longer period of hospitalization for the newborn and in the long run makes the living conditions more difficult. Taking the multifactorial pathogenesis into account, approaches to tackle chronic lung disease (CLD) are mainly focused on interventions and prevention procedures...

AIM: Less invasive surfactant administration (LISA) can avoid tracheal intubation for neonatal respiratory distress syndrome, but can be painful because it requires laryngoscopy. The aim of this study was to assess the efficacy and tolerance of intravenous atropine plus ketamine administration before LISA. METHODS: We conducted a prospective observational study of all premature infants hospitalised in our French neonatal intensive care unit treated with LISA between March 2015 and March 2016...

Biochemical networks mediating normal lung morphogenesis and function have important implications for ameliorating morbidity and mortality in premature infants. While several transcript-level studies have examined normal lung development, corresponding protein-level analyses are lacking. Here we performed proteomics analysis of murine lungs from embryonic to early adult ages to identify the molecular networks mediating normal lung development. We identified 8,932 proteins providing a deep and comprehensive view of the lung proteome...

BACKGROUND: Extremely premature neonates suffer high morbidity and mortality. An artificial placenta (AP) using extracorporeal life support (ECLS) is a promising therapy. OBJECTIVES: We hypothesized that intratracheal perfluorocarbon (PFC) instillation during AP support would reduce lung injury and promote lung development relative to intratracheal amniotic fluid or crystalloid. METHODS: Lambs at an estimated gestational age (EGA) 116-121 days (term 145 days) were placed on venovenous ECLS with jugular drainage and umbilical vein reinfusion and intubated...

BACKGROUND: Bronchopulmonary dysplasia (BPD) is the result of a complex process in which several prenatal and/or postnatal factors interfere with lower respiratory tract development, leading to a severe, lifelong disease. In this review, what is presently known regarding BPD pathogenesis, its impact on long-term pulmonary morbidity and mortality and the available preventive and therapeutic strategies are discussed. MAIN BODY: Bronchopulmonary dysplasia is associated with persistent lung impairment later in life, significantly impacting health services because subjects with BPD have, in most cases, frequent respiratory diseases and reductions in quality of life and life expectancy...

BACKGROUND: Premature infants are at high risk for developmental delay and cognitive dysfunction. Besides medical conditions, growth restriction is regarded as an important risk factor for cognitive and neurodevelopmental dysfunction throughout childhood and adolescence and even into adulthood. In this study, we analyzed the relationship between post-discharge body weight and psychomotor development using a nationwide dataset. MATERIALS AND METHODS: This was a nationwide cohort study conducted in Taiwan...

BACKGROUND: Despite improvements in perinatal care, bronchopulmonary dysplasia (BPD) in extremely premature infants has not decreased. Postnatal surfactant therapy provides symptomatic relief from respiratory distress syndrome, but does not translate into a reduction in BPD. Therefore, the search for effective interventions to prevent BPD continues. OBJECTIVES: Since PPAR-γ agonists have been demonstrated to promote neonatal lung maturation and injury repair, we hypothesized that a formulation of a PPAR-γ agonist, pioglitazone (PGZ) and a synthetic lung surfactant (a surfactant protein B peptide mimic, B-YL) combined would stimulate lung maturation and block hyperoxia-induced neonatal lung injury more effectively than either modality alone...

The study was performed on pregnant women with a gestational age of 26-32 weeks of pregnancy, who had been admitted to the hospital with a confirmed diagnosis of premature rupture of membranes. In all eligible women, ultrasounds were performed for the evaluation of amniotic fluid index. Then, the women were divided into two groups according to amniotic fluid index of ≥5 cm and <5 cm. These women were followed and monitored up to delivery. The women of the two groups did not have significant difference between them according to age, gestational age at the time of ruptured membrane, body mass index, gravidity, parity, gestational age at delivery and route of delivery...

Lung immaturity is the major cause of morbidity and mortality in premature infants, especially those born <28 weeks of gestation. These infants are at high risk of developing respiratory distress syndrome (RDS), a lung disease caused by insufficient surfactant production and immaturity of saccular/alveolar type II epithelial cells in the lung. RDS treatment includes oxygen and respiratory support that improve survival but also increase the risk for bronchopulmonary dysplasia (BPD), a chronic lung disease characterized by arrested alveolarization, airway hyperreactivity, and pulmonary hypertension...

BACKGROUND: Severe bronchopulmonary dysplasia (BPD) remains a major complication of prematurity and can have significant impact on long-term pulmonary sequelae and adverse neurodevelopmental outcomes. OBJECTIVE: To assess the incidence and evaluate the predictive factors for severe BPD in very preterm infants with respiratory distress syndrome. METHODS: Of the 846 premature infants born at ≤32-week gestation who developed respiratory distress syndrome (RDS), 707 infants with known oxygen dependency at 36 weeks gestational age were included in the analysis of BPD incidence...

BACKGROUND: There is limited evidence of the effect of positive end-expiratory pressure (PEEP) during resuscitation soon after birth. Premature neonates may experience respiratory distress from surfactant insufficiency and providing PEEP after the very first breath, may improve outcomes following appropriate resuscitation. The objective of this study was to evaluate the short term respiratory outcomes after positive pressure ventilation (PPV) with PEEP in preterm infants at birth. METHODS: A prospective randomized-controlled, pilot trial was conducted...

INTRODUCTION: 2-D ultrasound shear wave elastography (SWE) could be considered as a new noninvasive tool for monitoring fetal lung development based on evaluation of mechanical properties during pregnancy. Interesting results are available concerning the use of SWE on developing organs, especially on premature infants and animal models. The main objective in this study is to evaluate the feasibility of 2-D SWE in human fetal lungs between 24 and 34 weeks of gestation (WG). The secondary objective is to modellise fetal lung-to-liver elastography ratio (LLE ratio) and to assess variations between normal lung and lung surfactant-enriched after a corticosteroids course indicated for a threatened preterm labour (TPL)...

Vesicular P2X4 receptors are known to facilitate secretion and activation of pulmonary surfactant in the alveoli of the lungs. P2X4 receptors are expressed in the membrane of lamellar bodies (LBs), large secretory lysosomes that store lung surfactant in alveolar type II epithelial cells, and become inserted into the plasma membrane after exocytosis. Subsequent activation of P2X4 receptors by adenosine triphosphate (ATP) results in local fusion-activated cation entry (FACE), facilitating fusion pore dilation, surfactant secretion, and surfactant activation...

INTRODUCTION: Despite recent advances in respiratory support, the wide use of antenatal steroids and surfactant-replacement therapy, respiratory problems continue to represent the leading cause of mortality in premature infants during the neonatal period. In the last few years, HHHFNC has been widely adopted as a mode of noninvasive respiratory support for infants with respiratory difficulties. However, data of the safety and efficacy of HHHFNC use in extremely premature infants are scarce...
