To treat respiratory distress syndrome, surfactant is currently delivered via less invasive surfactant administration (LISA) or INtubation SURfactant Extubation (INSURE). The aim of this study was to compare the effect of the two delivery methods of surfactant on cerebral autoregulation. Near infrared spectroscopy monitoring was carried out to detect cerebral oxygen saturation (ScO2), and the mean arterial blood pressure (MABP) was simultaneously recorded. Of 44 preterm infants included, the surfactant was administrated to 22 via LISA and 22 via INSURE...

BACKGROUND: Respiratory distress syndrome (RDS) is a severe pulmonary disease that mainly affects preterm neonates. Surfactant-protein genes' polymorphisms have been mostly evaluated as the candidate contributors in genetics of RDS. However, the results are diverse in different populations. We aimed at investigating the association of rs1124 with RDS development. METHOD: Three hundred and thirty five preterm neonates were enrolled in a multicenter case-control study...

Timothy J M Moss, Alana J Westover
Intrauterine inflammation, or chorioamnionitis, is a major contributor to preterm birth. Prematurity per se is associated with considerable morbidity and mortality resulting from lung immaturity but exposure to chorioamnionitis reduces the risk of neonatal respiratory distress syndrome (RDS) in preterm infants. Animal experiments have identified that an increase in pulmonary surfactant production by the preterm lungs likely underlies this decreased risk of RDS in infants exposed to chorioamnionitis. Further animal experimentation has shown that infectious or inflammatory agents in amniotic fluid exert their effects on lung development by direct effects within the developing respiratory tract, and probably not by systemic pathways...

BACKGROUND AND OBJECTIVES: Newborns delivered late-preterm (between 340/7 and 366/7 weeks of gestation) are at increased risk of respiratory distress syndrome (RDS). Polymorphisms within the surfactant protein (SP) A and B gene have been shown to predispose to RDS in preterm neonates. The aim of this study was to investigate whether specific SP-A and/or SP-B genetic variants are also associated with RDS in infants born late-preterm. METHODS: This prospective cross-sectional study included 56 late-preterm infants with and 60 without RDS...

BACKGROUND: Synthetic surfactants represent a promising alternative to animal-derived preparations in the treatment of neonatal respiratory distress syndrome. The synthetic surfactant CHF5633 has proven biophysical effectiveness and, moreover, demonstrated anti-inflammatory effects in LPS-stimulated monocytes. With ureaplasmas being relevant pathogens in preterm lung inflammation, the present study addressed immunomodulatory features on Ureaplasma-induced monocyte cytokine responses. METHODS: Ureaplasma parvum-stimulated monocytes were exposed to CHF5633...

BACKGROUND: Assessing gestational age by ultrasound can introduce a systematic bias due to sex differences in early growth. METHODS: This cohort study included data on 1,314,602 births recorded in the Swedish Medical Birth Register. We compared rates of prematurity-related adverse outcomes in male infants born early term (gestational week 37-38) or late preterm (gestational week 35-36), in relation to female infants, between a time period when pregnancy dating was based on the last menstrual period (1973-1978), and a time period when ultrasound was used for pregnancy dating (1995-2010), in order to assess the method's influence on outcome by fetal sex...

Dexamethasone, a synthetic glucocorticoid, has been widely used to prevent or ameliorate morbidity of chronic lung disease in preterm infants with respiratory distress syndrome. Despite its beneficial effect on neonatal lung function, growing concern has arisen about adverse effects of this clinical practice on fetal brain development. We demonstrated previously that neonatal dexamethasone (DEX) treatment may render the newborn brain to be more vulnerable to hypoxia/ischemia (HI)-induced gray matter injury...

PURPOSE: Neonatal Respiratory Distress Syndrome (RDS) is a major cause of mortality and morbidity among preterm infants. Although the INSURE technique for surfactant replacement therapy is so far the gold standard method, over the last years new approaches have been studied, i.e. LISA or MIST. Here we propose an originally modified MIST, called CALMEST (Catheter And Laryngeal Mask Endotracheal Surfactant Therapy), using a particular laryngeal mask as a guide for a thin catheter to deliver surfactant directly in the trachea...

OBJECTIVE: To evaluate short- and long-term benefits and risks associated with antenatal administration of a single course of corticosteroids and the related strategies: multiple and rescue courses. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Antenatal administration of a single course of corticosteroids before 34 weeks of gestation is associated in the neonatal period with a significant reduction of respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC) and death (LE1), and in possibly childhood with a reduction of cerebral palsy and increased psychomotor development index and intact survival (LE3)...

OBJECTIVE: To determine whether adverse outcomes were more common in late preterm pregnancies complicated by preeclampsia and growth restriction compared to those affected by preeclampsia alone. METHODS: This was a retrospective cohort study of 8,927 singleton pregnancies with preeclampsia. Pregnancies with small for gestational age (SGA) neonates (birthweight <10(th) percentile) were compared to those appropriate for gestational age (AGA) neonates. Maternal outcomes included cesarean delivery (CD) rate, CD for fetal heart rate (FHR) abnormalities, abruption, postpartum hemorrhage (PPH), maternal transfusion, acute renal failure, and peripartum cardiomyopathy...

Introduction The incidence and risk factors for inguinal hernia (IH) is not a thoroughly evaluated issue of preterms. Prematurity is the single most important risk factor. There exists no study in our country which reported the incidence of IH in preterms. The purpose of this study is to investigate the incidence and time of diagnosis of IH in very low-birth-weight (VLBW) infants. Patients and Methods This retrospective case-control study was conducted in Etlik Zubeyde Hanim Women's Health Training and Research Hospital and included discharged VLBW infants with gestational age less than 32 weeks...
