Transplanting enteric neural stem cells (ENSCs) is an innovative approach for replacing enteric neurons in Hirschsprung's disease (HSCR). However, posttransplantation cell survival and differentiation limit efficacy. We aimed to investigate whether transplantation of ENSCs engineered with insulin-like growth factor 1 (IGF-1) could improve survival and differentiation of the engrafted cells and promote functional recovery of the aganglionic colon. ENSCs were isolated from the intestine of neonatal mice and genetically modified to express IGF-1...

BACKGROUND: To investigate the trends in the incidence and associated factors of late-onset sepsis (LOS) associated with improved survival in extremely preterm infants. METHODS: Medical records of 364 infants who were born at 23-26 weeks' gestation from 2000 to 2005 (period I, n = 124) and from 2006 to 2011 (period II, n = 240) were retrospectively reviewed. The infants were stratified into subgroups of 23-24 and 25-26 weeks' gestation within each period, and survival, LOS rate, and clinical characteristics were analyzed...

PurposeInfants admitted to a level IV neonatal intensive care unit (NICU) who do not survive early childhood are a population that is probably enriched for rare genetic disease; we therefore characterized their genetic diagnostic evaluation.MethodsThis is a retrospective analysis of infants admitted to our NICU between 1 January 2011 and 31 December 2015 who were deceased at the time of records review, with age at death less than 5 years.ResultsA total of 2,670 infants were admitted; 170 later died. One hundred six of 170 (62%) had an evaluation for a genetic or metabolic disorder...

Respiratory distress syndrome (RDS) impacts a high proportion of preterm neonates, resulting in significant morbidity and mortality. Advances in pharmacotherapy, specifically antenatal corticosteroids and postnatal surfactant therapy, have significantly reduced the incidence and impact of neonatal RDS. Antenatal corticosteroids accelerate fetal lung maturation by increasing the activity of enzymes responsible for surfactant biosynthesis, resulting in improved lung compliance. Maternal antenatal corticosteroid treatment has improved survival of preterm neonates and lowered the incidence of brain injury...

INTRODUCTION: Neonatal and pediatric ECMO is a high-risk procedure that should be performed only in expert centers. Children who are eligible for ECMO and are managed in hospitals without ECMO capabilities should be referred to the closest ECMO center before the severity of illness precludes safe conventional transport. When the clinical situation precludes safe conventional transport, ECMO should be provided on site with the patient transported on ECMO. METHODS: We retrospectively reviewed our institutional database of all ECMO transports for neonatal and pediatric respiratory failure from February 2013 to February 2018...

PURPOSE: With the exception of neonatal respiratory failure, most centers are now using centrifugal over roller-type pumps for the delivery of extracorporeal membrane oxygenation (ECMO). Evidence supporting the use of centrifugal pumps specifically in infants with congenital diaphragmatic hernia (CDH) remains lacking. We hypothesized that the use of centrifugal pumps in infants with CDH would not affect mortality or rates of severe neurologic injury (SNI). METHODS: Infants with CDH were identified within the ELSO registry (2000-2016)...

OBJECTIVES: Tricuspid valve (TV) competence is important for successful palliation of hypoplastic left heart syndrome (HLHS). We report our experience with TV repair in HLHS patients with a focus on TV and right ventricular (RV) function and associated clinical outcomes. METHODS: From 2002 to 2012, 219 neonates with HLHS underwent the Norwood operation. Thirty patients who underwent TV repair at various stages comprised our current series cohort. Echocardiographic and clinical data were reviewed to determine the effectiveness of TV repair and outcomes of the patients...

BACKGROUND: Effective coverage requires that those in need can access skilled care supported by adequate resources. There are, however, few studies of effective coverage of facility-based neonatal care in low-income settings, despite the recognition that improving newborn survival is a global priority. METHODS: We used a detailed retrospective review of medical records for neonatal admissions to public, private not-for-profit (mission) and private-for-profit (private) sector facilities providing 24×7 inpatient neonatal care in Nairobi City County to estimate the proportion of small and sick newborns receiving nationally recommended care across six process domains...

BACKGROUND: Minimally invasive surgery (MIS) has gained increasing importance in neonatal surgery but the effects on neonatal physiology remain unclear. We aimed to characterize the impact of capnoperitoneum on physiologic parameters in a small animal model for neonatal MIS. MATERIAL AND METHODS: Twenty-four 10-day-old Sprague Dawley rats underwent inhalative anesthesia (1% isoflurane in 100% O2 250 mL/minutes) and were allowed to breathe spontaneously. CO2 was insufflated into the abdominal cavity for 1 hour via a 24G cannula...

For neonates with right atrial isomerism (RAI), functional single ventricle (f-SV), and obstructive total anomalous pulmonary venous connection (TAPVC), primary TAPVC repair (TAPVCR) has a poor outcome. At our hospital, the survival rate at 1 year of such neonates undergoing primary TAPVCR between 1999 and 2010 (TAPVCR group) was 30% (3/10). Most deceased cases suffered from capillary leak syndrome and unstable pulmonary resistance after the surgeries. We sought to determine whether less invasive primary draining vein stenting (DVS) improved the outcome of these neonates...

BACKGROUND: We aim to examine the effect of genetic syndromes and extracardiac anomalies (GS/EC) on single ventricle (SV) palliation with focus on hospital death, interstage mortality, and progression towards subsequent palliation stages. METHODS: 530 neonates with SV underwent first-stage palliation: Norwood (n=284,53%), shunt (n=173,33%), band (n=73,14%). Outcomes were compared between those with GS/EC (n=121,23%) and without GS/EC (n=409,77%). Regression analyses were adjusted for other risk factors (age, gender, prematurity, weight, SV anomaly, first-stage palliation surgery)...

Background: The post-myocardial infarction (MI) scar interrupts electrical impulse propagation and delays regional contraction, which contributes to ventricular dysfunction. We investigated the potential of an injectable conductive biomaterial to restore scar tissue conductivity and re-establish synchronous ventricular contraction. Methods: A conductive biomaterial was generated by conjugating conductive polypyrrole (PPY) onto chitosan (CHI) backbones. Trypan blue staining of neonatal rat cardiomyocytes (CMs) cultured on biomaterials was used to evaluate the biocompatibility of the conductive biomaterials...

Human milk provides immunoglobulins (Igs) that supplement the passive immune system of neonates; however, the extent of survival of these Igs during gastric digestion and whether this differs between preterm and term infants remains unknown. Human milk, and infant gastric samples at 2 h post-ingestion were collected from 15 preterm (23⁻32 week gestational age (GA)) mother-infant pairs and from 8 term (38⁻40 week of GA) mother-infant pairs within 7⁻98 days postnatal age. Samples were analyzed via ELISA for concentration of total IgA (secretory IgA (SIgA)/IgA), total secretory component (SC/SIgA/SIgM), total IgM (SIgM/IgM), and IgG as well as peptidomics...

The development and refinement of cardiopulmonary bypass (CPB) has made the repair of complex congenital heart defects possible in neonates and infants. In the past, the primary goal for these procedures was patient survival. Now that substantial survival rates have been achieved for even the most complex of repairs in these patients, focus has been given to the reduction of morbidity. Although a necessity for these complex neonatal and infant heart defect repairs, CPB can also be an important source of perioperative complications...

BACKGROUND: Little is know about whether the effects of community engagement interventions for child survival in low-income and middle-income settings are sustained. Seasonal variation and secular trend may blur the data. Neonatal mortality was reduced in a cluster-randomised trial in Vietnam where laywomen facilitated groups composed of local stakeholders employing a problem-solving approach for 3 years. In this analysis, we aim at disentangling the secular trend, the seasonal variation and the effect of the intervention on neonatal mortality during and after the trial...

BACKGROUND: About three - quarters of all neonatal deaths occur during the first week of life, with over half of these occurring within the first 24 h after birth. The first minutes after birth are critical to reducing neonatal mortality. Successful neonatal resuscitation (NR) has the potential to prevent these perinatal mortalities related to birth asphyxia. This study described the practice of NR and outcomes of newborns with birth asphyxia in a busy referral hospital. METHODS: Direct observations of 138 NRs by 28 healthcare providers (HCPs) were conducted using a predetermined checklist adapted from the national pediatric resuscitation protocol...

BACKGROUND/AIMS: An increased preterm birth survival rate is associated with long-term neurological and metabolic risks; thus, our aim was to evaluate whether early patterns of infancy anthropometry and metabolic hormonal profile differ in preterm infants born small for gestational age (SGA) or appropriate for gestational age (AGA) from birth to 36 months of corrected age (CA). METHODS: We recruited 110 very-low-birth-weight (VLBW) preterm infants (AGA = 60 and SGA = 50) with a mean birth weight of -2...
