STUDY DESIGN: A retrospective review of infants born VPT or with VLBW and admitted to UCI Medical Center between 1/1/2012 and 12/31/2020. Repeat thyroid screening was obtained at 1 month of life (+ 10 days)...

RATIONALE: Summarizing the perioperative nursing experience in the successful treatment of 4 neonates with critical pulmonary stenosis (CPS). PATIENT CONCERNS: Of the 4 patients, 3 had postnatal shortness of breath and varying degrees of cyanosis, aggravated by crying and noise, and 1 had no obvious shortness of breath and cyanosis. The preoperative auscultation of the precordial region could be heard 3-4/6 systolic murmur; echocardiography was diagnosed as CPS, combined with patent ductus arteriosus, right ventricular dysplasia, and severe tricuspid regurgitation...

BACKGROUND: Persistent pulmonary hypertension of the neonate (PPHN) is a serious disorder. The long pentraxin 3 (PTX3) plays an important role in angiogenesis, cell proliferation, tissue repair and cell regulation. The present study aims to assess the diagnostic and clinical value of PTX3 in PPHN. METHODS: The present case-control 60 full-term neonates diagnosed with PPHN by echocardiography within 72 hours of birth. In addition, there were 30 age and sex-matched healthy neonates who served as controls...

BACKGROUND: We aimed to investigate the clinical characteristics and outcomes of patients with isolated left-sided congenital diaphragmatic hernia (CDH) who developed preoperative pneumothorax and determine its risk factors. METHODS: We performed an international cohort study of patients with CDH enrolled in the Congenital Diaphragmatic Hernia Study Group registry between January 2015 and December 2020. The main outcomes assessed included survival to hospital discharge and preoperative pneumothorax development...

PURPOSE: We aimed to investigate the role of lung ultrasound (LUS) score in the closure of hemodynamically insignificant patent ductus arteriosus (PDA) and the clinical findings of the patients before and after closure. METHODS: The study groups (107 preterm neonates under 34 gestational weeks) were classified as hemodynamically significant PDA (group 1), hemodynamically insignificant PDA with closure therapy (group 2), hemodynamically insignificant PDA without closure therapy (group 3), and no PDA group (group 4) based on the echocardiography...

BACKGROUND: Neonates with critical congenital heart disease of the ductal-dependent pulmonary circulation type (CCHD-DDPC) require prostaglandin E1 (PGE1) to maintain oxygen saturation until surgery. However, the factors contributing to the maintenance doses of PGE1 remain unclear. This study aimed to determine the predictors of high maintenance PGE1 doses in these neonates. METHODS: This retrospective cohort study included neonates with CCHD-DDPC at Songklanagarind Hospital between January 1, 2006, and December 31, 2021...

RATIONALE: The resiliency of embryonic development to genetic and environmental perturbations has been long appreciated; however, little is known about the mechanisms underlying the robustness of developmental processes. Aberrations resulting in neonatal lethality are exemplified by congenital heart disease (CHD) arising from defective morphogenesis of pharyngeal arch arteries (PAA) and their derivatives. OBJECTIVE: To uncover mechanisms underlying the robustness of PAA morphogenesis...

BACKGROUND: Intraventricular hemorrhage (IVH) is an important cause of neurodevelopmental impairment in preterm infants. A number of risk factors for IVH have already been proposed; however, some controversies regarding optimal perinatal management persist. This study aimed to identify perinatal and neonatal attributes associated with IVH in a representative population of preterm infants. METHODS: Perinatal data on 1,279 very preterm infants (<32 weeks of gestation) admitted to a tertiary neonatal intensive care unit were analyzed...

BACKGROUND: Longer hospitalizations for preterm infants with bronchopulmonary dysplasia (BPD) delay developmental outcomes, increase the risk for hospital-acquired complications, and exert a substantial socioeconomic burden. This study aimed to identify factors associated with an extended length of stay (LOS) at different levels of severity of BPD. METHODS: A cohort study was conducted using the Korean Neonatal Network registry of very low birth weight infants with BPD between 2013 and 2017 through retrospective analysis...

OBJECTIVE: As the predominant complication in preterm infants, Bronchopulmonary Dysplasia (BPD) necessitates accurate identification of infants at risk and expedited therapeutic interventions for an improved prognosis. This study evaluates the potential of Monosaccharide Composite (MC) enriched with environmental information from circulating glycans as a diagnostic biomarker for early-onset BPD, and, concurrently, appraises BPD risk in premature neonates. MATERIALS AND METHODS: The study incorporated 234 neonates of ≤32 weeks gestational age...

Neonatologist Performed Echocardiography (NPE) is one of the emerging technologies used to evaluate Systemic Blood Flow (SBF) in term and preterm infants. Right Ventricular Output (RVO) can assess SBF correctly in the absence of significant interatrial or interventricular shunts, even in the presence of a large patent ductus arteriosus (PDA), but only few studies evaluated inter-observer variability in neonates. Furthermore, measuring pulmonary peak flow (PF) provides a simple screening tool for low SBF state, easier and faster to perform than RVO; no previous studies evaluated PF inter-observer variability...

OBJECTIVES: This study aims to describe the effectiveness of low initial alprostadil dosages to maintain a patent ductus arteriosus (PDA) in infants with ductal-dependent congenital heart disease (DDCHD). Secondary objectives were to describe any adverse drug events, describe prescribing trends, describe ductus arteriosus diameter changes, and compare the safety and efficacy of very low and low initial alprostadil dosage regimens. METHODS: This retrospective observational cohort study at the British Columbia's Women's and Children's Hospital neonatal intensive care unit and pediatric intensive care unit examined neonates admitted with DDCHD who received alprostadil to maintain ductal patency...

UNLABELLED: Portosystemic venous shunts (PSVS) are malformations that result from abnormal communications between the portal and hepatic veins or inferior vena cava. Prenatal diagnosis is made by evaluating the fetal venous circulation and it is classified as intrahepatic and extrahepatic, with different evolution and complications. OBJECTIVE: To report two cases of prenatal diagnosis of portosystemic vascular shunts and review the importance of this rare pathology in its neonatal and pediatric evolution...

BACKGROUND: We report a low-birth-weight child (1.8 kg) with neonatal type III congenital esophageal atresia (CEA) combined with symptomatic patent ductus arteriosus (PDA). After comprehensive evaluation, esophageal anastomosis was performed on postnatal day 11 after excluding surgical contraindications, and arterial catheter ligation was performed at the same time. Concurrent surgery for CEA combined with PDA has not been clearly reported in the literature. CASE SUMMARY: We report a 6-day-old female child with type III CEA and PDA...

OBJECTIVE:  Magnesium sulfate (MgSO4 ) provides effective fetal neuroprotection. However, there is conflicting evidence regarding the association between antenatal MgSO4 exposure and patent ductus arteriosus (PDA). Thus, herein, we aimed to evaluate the association between antenatal MgSO4 exposure and PDA. STUDY DESIGN:  Preterm infants born between 240/7 and 316/7 weeks of gestation were included in this retrospective study. Infants who died within the first 72 hours of life and those with significant congenital anomalies were excluded from the study...

BACKGROUND: The ideal follow-up of neonates who have a secundum atrial septal defect (ASD), muscular ventricular septal defect (VSD) or patent ductus arteriosus (PDA) remains uncertain. METHODS: Newborns with findings limited to a secundum ASD, muscular VSD and/or PDA on their last birth hospital echocardiogram and at least one outpatient follow-up echocardiogram performed between 9-1-17 and 9-1-21 were evaluated and patient follow-up assessed through 9-1-23. RESULTS: 95 babies met inclusion criteria...

BACKGROUND: The similarity in the mechanism of action between paracetamol and ibuprofen can cause similar side effects. However, in preterm neonates with feeding intolerance, intravenous (IV) paracetamol has replaced oral ibuprofen. Therefore, a comparison of the effectiveness and side effects is essential. METHODS: In this retrospective cohort study, the data of 118 preterm infants with a definite diagnosis of patent ductus arteriosus (PDA), including 59 patients who received oral ibuprofen and 59 patients who received IV paracetamol were analyzed...
