BACKGROUND: Limited data exist regarding the neonatal and neurodevelopmental outcomes of infants exposed to marijuana (MJ) in-utero, particularly among preterm infants. We hypothesized that MJ-exposed preterm infants would have worse neonatal and childhood developmental outcomes compared to MJ-unexposed infants. METHODS: Secondary analysis of multicenter randomized-controlled trial of antenatal magnesium sulfate for prevention of cerebral palsy was conducted. Singleton non-anomalous infants delivered <35 weeks exposed to MJ in-utero were compared to MJ-unexposed...

Objective Angiogenesis is essential for normal lung development. The objective of our study was to test the hypothesis that preeclampsia, an antiangiogenic state, is a risk factor for bronchopulmonary dysplasia (BPD). Design Prospective cohort study of infants less than 32 weeks' gestation born to mothers with preeclampsia between January 2007 and June 2010 at a single tertiary care center. Their BPD outcome was compared with infants born to the next two normotensive mothers with a ± 1 week gestational age difference...

Importance: Clinicians aim to extubate preterm infants as early as possible, to minimize the risks of mechanical ventilation. Extubation is often unsuccessful owing to lung disease or inadequate respiratory drive. Objective: To conduct a systematic review and meta-analysis of interventions to improve rates of successful extubation in preterm infants. Data Sources: Searches were undertaken in PubMed and The Cochrane Library. Study Selection: The review was conducted using the methods of the Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

BACKGROUND: Denying parents access to their infant in the Neonatal Intensive Care Unit (NICU) is a standard practice in most hospitals across China. Visitation is not usually permitted or may be strictly limited, and NICU care for most neonates is provided by health-care professionals with little participation of the parents. An exception to this rule is the level 2 "Room-In" ward in Qilu Children's Hospital, Shandong University, where parents have 24-hour access to their infants and participate in providing care...

Bronchopulmonary dysplasia (BPD) is the most common complication of preterm birth, with appreciable morbidity and mortality in a neonatal intensive care setting. Much interest has been shown in the identification of pathogenic pathways that are amenable to pharmacological manipulation (1) to facilitate the development of novel therapeutic and medical management strategies and (2) to identify the basic mechanisms of late lung development, which remains poorly understood. A number of animal models have therefore been developed and continue to be refined with the aim of recapitulating pathological pulmonary hallmarks noted in lungs from neonates with BPD...

Objective To observe silent information regulator 1 (SIRT1) expression in the peripheral blood mononuclear cells (PBMCs), and explore the relationship between SIRT1 expression and bronchopulmonary dysplasia (BPD) in premature infants after oxygen exposure. Methods Premature infants with 28 to 30 weeks' gestation were divided into three groups according to the fraction of inspiration O2 (FiO2): low-oxygen group with FiO2<30%, medium-oxygen group with FiO2 being 30%~40%, and high-oxygen group with FiO2≥40%; other premature infants with 28 to 30 weeks' gestation and without inspiration O2 served as a control group...

The aim of this study was to assess the differences in the mortality and in-hospital outcomes of preterm infants with < 28 weeks of gestation who received ibuprofen treatment according to the presence of clinical symptoms (any of oliguria, hypotension, or moderate to severe respiratory difficulty) attributable to hemodynamically-significant patent ductus arteriosus (hsPDA) at the time of first ibuprofen treatment. In total, 91 infants born from April 2010 to March 2015 were included. Fourteen infants (15...

Bronchopulmonary dysplasia (BPD) is a chronic lung injury characterized by impaired alveologenesis that may persist into adulthood. Rat models of BPD using varying degrees of hyperoxia to produce injury either cause early mortality or spontaneously recover following removal of the inciting stimulus, thus limiting clinical relevance. We sought to refine an established rat model induced by exposure to 60% O2 from birth by following hyperoxia with intermittent hypoxia (IH). Rats exposed from birth to air or 60% O2 until day 14 were recovered in air with or without IH (FiO2 = 0...

We assessed the association between antibiotic exposure in the first 2 weeks of life and development of bronchopulmonary dysplasia in a cohort of very low birth weight infants. After controlling for the severity of illness, each additional day of antibiotic therapy was associated with both an increased risk for and severity of bronchopulmonary dysplasia.

Preterm infants are susceptible to inflammation-induced white matter injury but the exposures that lead to this are uncertain. Histologic chorioamnionitis (HCA) reflects intrauterine inflammation, can trigger a fetal inflammatory response, and is closely associated with premature birth. In a cohort of 90 preterm infants with detailed placental histology and neonatal brain magnetic resonance imaging (MRI) data at term equivalent age, we used Tract-based Spatial Statistics (TBSS) to perform voxel-wise statistical comparison of fractional anisotropy (FA) data and computational morphometry analysis to compute the volumes of whole brain, tissue compartments and cerebrospinal fluid, to test the hypothesis that HCA is an independent antenatal risk factor for preterm brain injury...

BACKGROUND: In the past several years, randomized controlled trials (RCTs) have indicated that inhaled nitric oxide (iNO) can potentially lower for both the incidence of bronchopulmonary dysplasia (BPD) and mortality in affected infants. Other research has, however, disagreed with these findings. MATERIALS AND METHODS: We performed an updated meta analysis of all relevant RCTs to assess the benefits of iNO in preterm infants by searching PubMed, EMBASE, Cochrane databases, Wanfang, VIP, and CNKI databases for English and Chinese references...

Arginase and nitric oxide synthase (NOS) share a common substrate, l-arginine, and have opposing effects on vascular remodeling. Arginase is the first step in polyamine and proline synthesis necessary for cellular proliferation, while NO produced from NOS promotes apoptosis. Previously, we identified a single nucleotide polymorphism (SNP) in the arginase-1 (ARG1) gene, rs2781666 (T-allele) that was associated with a decreased risk for developing pulmonary hypertension (PH) in a cohort of infants with bronchopulmonary dysplasia (BPD)...

BACKGROUND: Bronchopulmonary dysplasia (BPD) portends lifelong organ impairment and death. Our ability to predict BPD in first days of life is limited, but could be enhance using novel biomarkers. METHODS: Using an available clinical and urine biomarker database obtained from a prospective 113 infant cohort (birth weight ≤1200 g and/or gestational age ≤31 weeks), we evaluated the independent association of 14 urine biomarkers with BPD/mortality. RESULTS: Two of the 14 urine biomarkers were independently associated with BPD/mortality after controlling for gestational age (GA), small for gestational age (SGA), and intubation status...

Premature birth (<37 weeks gestation) occurs in ~11% of all births in the US. These infants are at risk of chronic lung disease and respiratory conditions, including bronchopulmonary dysplasia. Respiratory viruses are important causes of acute respiratory illness (ARI) in preterm infants, leading to rehospitalization, increased health care burden, and long-term morbidity. Human metapneumovirus (HMPV) is a paramyxovirus discovered in 2001 that is related to respiratory syncytial virus. Epidemiologic studies show that HMPV is a leading cause of ARI in children and adults worldwide...

AIM: To analyze possible factors associated with the quality of life (QoL) of mothers of preterm infants with very low birth weight (VLBW) during the first 3 years after delivery. METHODS: The World Health Organization Quality of Life (WHOQOL)-bref scores were compared and correlated with maternal and infant-related sociodemographic and clinical variables at maternal discharge (T0) and at 6 (T1), 12 (T2), 24 (T3), and 36 (T4) months after delivery. Multiple linear regression models were fitted to investigate the effect of these variables on the mothers' QoL...

AIM: Respiratory distress syndrome (RDS) is a major cause of mortality and morbidity in premature infants. By the time symptoms appear it may already be too late to prevent a severe course, with bronchopulmonary dysplasia or mortality. We aimed to develop a rapid test of lung maturity for targeting surfactant supplementation. METHODS: Concentrations of the most surface-active lung phospholipid dipalmitoylphosphatidylcholine and sphingomyelin in gastric aspirates from premature infants were measured by mass spectrometry and expressed as the lecithin/sphingomyelin ratio (L/S)...
