Yo Han Seo, Hee Joung Choi
Background: We evaluated early and late pulmonary hypertension (PH) in preterm infants and its relation with bronchopulmonary dysplasia (BPD). Methods: Sixty-seven preterm infants < 30 weeks' gestation underwent echocardiography within 14 days after birth for early PH and over 28 days after birth for late PH. We measured tricuspid regurgitation (TR) peak velocity, pulse Doppler-derived myocardial performance index (MPI) of right ventricle (RV) (RV MPI), eccentricity index (EI), and tricuspid annular plane systolic excursion (TAPSE)...

BACKGROUND: At three weeks of age, a previous 34 weeks' gestation male infant (twin A) was transferred to our regional perinatal center (RPC) with complaints of poor oral feeding and intermittent tachypnea. Twin B was discharged at 37 weeks with an uneventful course. CASE: Twin A briefly required respiratory support but continued to have difficulty transitioning from gavage to oral feeding. Initially, his inability to feed orally was thought to be secondary to nasal congestion and prematurity, but with worsening respiratory distress he was transferred for further evaluation and management...

Identifying new targets that regulate myometrial activation are required to develop effective treatments to stop preterm labor. Inflammation, which can be induced by sterile or infective insults, plays a role in initiating and maintaining uterine contractions. Several high throughput transcription screening studies have identified an upregulation of runt-related transcription factor 1 (RUNX1) mRNA expression in myometrium with labor. The role of RUNX1 in labor, however, is not known. We report increased RUNX1 during late gestation which was further augmented in labor, suggesting that RUNX1 may be involved in the transition of the myometrium from a quiescent into a contractile state in preparation for labor...

BACKGROUND: Preterm infants are at high risk for extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) sepsis and neonatal intensive care unit (NICU) outbreaks. Maternal colonization with ESBL-E may be precursory to maternal-neonatal transmission. However, there is no consensus regarding surveillance of pregnant women for ESBL-E colonization. AIM: To identify pairs of mothers and offspring harbouring same-strain ESBL-E colonization and to determine whether maternal transmission may play a role in increasing ESBL-E carriage in preterm infants...

Dexamethasone, a synthetic long-acting glucocorticoid, is routinely used for treating mothers at risk for preterm delivery. However, intrauterine overexposure to glucocorticoids induces low birth weight and cartilage dysplasia in offspring. Also, the "critical window" and safe dose of this treatment are largely unknown. This study investigated the course-, dose-, and stage-dependent toxic effects and the possible mechanisms of prenatal dexamethasone exposure (PDE) on fetal development and articular cartilage development...

Ongoing advancements in neonatal care since the late 1980's have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia (BPD), is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions...

OBJECTIVE: To compare the effects of immediate delivery an expectant management among women whose pregnancies were complicated by preterm prelabor rupture of membranes (PROM) in the late preterm period (from 34 0/7 weeks until 36 6/7 weeks of gestation). DATA SOURCES: PubMed, Scopus, ClinicalTrials.gov, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from inception until December 2016. METHODS OF STUDY SELECTION: We included all randomized controlled trials with individual participant data reporting on late preterm PROM with randomization to immediate delivery or expectant management...

Preterm birth is widespread and causes 35% of all neonatal deaths. Infants who survive face potential long-term complications. A major contributing factor of preterm birth is infection. We investigated the role of Interleukin 22 (IL22) as a potential clinically relevant cytokine during gestational infection. IL22 is an effector molecule secreted by immune cells. While the expression of IL22 was reported in normal non-pregnant endometrium and early pregnancy decidua, little is known about uterine IL22 expression during mid- or late gestational stages of pregnancy...

BACKGROUND: Late preterm (LPT) newborns, defined as those born between 34 0/7 and 36 6/7 gestational weeks, have higher short- and long-term morbidity and mortality than term infants (≥37 weeks). A categorization to justify a non-spontaneous LPT delivery has been proposed to distinguish evidence-based from non-evidence-based criteria. This study aims to describe rates and temporal trends of non-spontaneous LPT neonates delivered according to evidence-based or non-evidence-based criteria and to evaluate the number of avoidable LPT deliveries, including severe neonatal morbidity rates and associated risk factors...

There is no consensus regarding how the growth of preterm infants should be monitored or what constitutes their ideal pattern of growth, especially after term-corrected age. The concept that the growth of preterm infants should match that of healthy fetuses is not substantiated by data and, in practice, is seldom attained, particularly for very preterm infants. Hence, by hospital discharge, many preterm infants are classified as postnatal growth-restricted. In a recent systematic review, 61 longitudinal reference charts were identified, most with considerable limitations in the quality of gestational age estimation, anthropometric measures, feeding regimens, and how morbidities were described...

BACKGROUND: Adverse pregnancy outcomes, such as preterm birth (PTB), have been associated with elevated risk of maternal cardiovascular disease, but their effect on late midlife blood pressure (BP) and subclinical vascular measures remains understudied. METHODS AND RESULTS: We conducted a cross-sectional analysis with 1220 multiethnic parous women enrolled in SWAN (Study of Women's Health Across the Nation) to evaluate the impact of self-reported history of adverse pregnancy outcomes (PTB, small-for-gestational-age, stillbirth), on maternal BP, mean arterial pressure, and subclinical vascular measures (carotid intima-media thickness, plaque, and pulse wave velocity) in late midlife...

There is growing interest in the Kaiser early-onset sepsis (EOS) risk calculator though institutions are hesitant to deviate from the Centers for Disease Control and Prevention guidelines and implement this in their hospitals. We describe the process of implementing routine use of the risk calculator in term and late preterm newborns delivered to mothers with chorioamnionitis in a level III neonatal intensive care unit (NICU). A retrospective chart review of infants delivered to mothers with chorioamnionitis from 2011 to 2014 was performed...

BACKGROUND: Pulmonary disorders and respiratory failure represent one of the most common morbidities of preterm newborns admitted to neonatal intensive care units (NICUs). The use of nasal high-flow therapy (nHFT) has been more recently introduced into the NICUs as a non-invasive respiratory (NIV) support. METHODS: We performed a retrospective study to evaluate safety and effectiveness of nHFT as primary support for infants born < 29 weeks of gestation and/or VLBW presenting with mild Respiratory Distress Syndrome (RDS)...

Chronic intervillositis of unknown etiology (CIUE) is a poorly understood, relatively rare condition characterized histologically by the intervillous infiltration of mononuclear cells in the placenta. Clinically, CIUE is associated with poor pregnancy outcome (e.g., impaired fetal growth, preterm birth, fetal death) and high risk of recurrence in subsequent pregnancies. Because CIUE is not defined consistently, it is essential to clearly define this condition. We therefore review the published definitions of CIUE...

BACKGROUND: There is growing evidence that supports the benefits of early use of caffeine in preterm neonates with RDS; however, no formal recommendations specifying the exact timing of therapy initiation have been provided. OBJECTIVES: We compared neonatal outcomes in infants receiving early (initial dose on the 1st day of life) and late (initial dose on day 2+ of life) caffeine therapy. METHODS: Using data from a prospective, cohort study, we identified 986 infants ≤32 weeks' gestation with RDS and assessed the timing of caffeine therapy initiation, need for ventilatory support, mortality and incidence of typical complications of prematurity...

Studies using videotape recordings and respiratory function monitoring have shown that both face mask (FM) application and endotracheal tube (ETT) placement represent a challenge for resuscitators. Hence, there is a strong need for devices that can largely be used independently of individual operator training levels, in order to ensure more reliable support in time-critical situations, such as neonatal resuscitation. The laryngeal mask airway device (LMA) has evolved as a potentially very valuable tool. We conducted a systematic review of studies evaluating the use of the LMA in neonatal resuscitation...
