A diagnosis of intra-amniotic infection is typically made based on clinical criteria, including maternal intrapartum fever and one or more of the following: maternal leukocytosis, purulent cervical drainage, or fetal tachycardia. The diagnosis can also be made in patients with an isolated fever of 39°C, or greater, without any other clinical risk factors present. Coronavirus disease 2019 (COVID-19), caused by the virus SARS-CoV-2, has been noted to have varying signs and symptoms over the course of the disease including fever, cough, fatigue, anorexia, shortness of breath, sputum production, and myalgia. In this report, we detail a case of a newborn born to a mother with a clinical diagnosis of intra-amniotic infection with maternal fever and fetal tachycardia, who was then found to be SARS-CoV-2 positive on testing. Due to the varying presentation of COVID-19, this case illustrates the low threshold needed to test mothers for SARS-CoV-2 in order to prevent horizontal transmission to neonates and to healthcare providers.

OBJECTIVE:To compare the electrical activity of the diaphragm (Edi) of premature infants placed on continuous positive airway pressure (CPAP) with the Edi of premature infants placed on noninvasive neurally adjusted ventilatory assist (NIV NAVA). The secondary aim was to evaluate the feasibility of the use of NIV NAVA mode in the busy tertiary neonatal unit. STUDY DESIGN/METHODS:This was a prospective crossover pilot study of premature infants requiring noninvasive respiratory support. Infants were randomized to initially receive either CPAP/biphasic (group 1) or NIV NAVA (group 2) and were then crossed over to the alternate group. Continuous Edi signals were recorded for 24 h, with 12 h each on CPAP/biphasic, and NIV NAVA along with other clinical and respiratory parameters.  Results: Ten infants with a mean gestation age of 29 weeks (range 25-34 weeks) were enrolled, with a total cumulative Edi monitoring of 240 h. The average Edi peak on the biphasic/CPAP group (15.6 ± 7 mcV) was significantly higher (P < 0.005), compared to the Edi Peak on the NIV NAVA group (10.8 ± 3.3 mcV). The Edi min values were 3.23 ± 1.1 mcV, and 3.07 ± 0.5 mcV on CPAP/biphasic and NIV NAVA (P = 0.69) respectively. There were no significant differences in other clinical parameters between the two groups. No major adverse events were recorded during Edi catheter monitoring. CONCLUSION/CONCLUSIONS:The Edi peak values were significantly lower in NIV NAVA mode compared to CPAP/biphasic mode. The Edi catheter and NIV NAVA may also be used safely in premature infants.

Hypoxic-ischemic encephalopathy is a subtype of neonatal encephalopathy and a major contributor to global neonatal morbidity and mortality. Despite advances in obstetric and neonatal care there are still challenges in accurate determination of etiology of neonatal encephalopathy. Thus, identification of intrapartum risk factors and comprehensive evaluation of the neonate is important to determine the etiology and severity of neonatal encephalopathy. In developed countries, therapeutic hypothermia as a standard of care therapy for neonates with hypoxic-ischemic encephalopathy has proven to decrease incidence of death and neurodevelopmental disabilities, including cerebral palsy in surviving children. Advances in neuroimaging, brain monitoring modalities, and biomarkers of brain injury have improved the ability to diagnose, monitor, and treat newborns with encephalopathy. However, challenges remain in early identification of neonates at risk for hypoxic-ischemic brain injury, and determination of the timing and extent of brain injury. Using imaging studies such as Neonatal MRI and MR spectroscopy have proven to be most useful in predicting outcomes in infants with encephalopathy within the first week of life, although comprehensive neurodevelopmental assessments still remains the gold standard for determining long term outcomes. Future studies are needed to identify other newborns with encephalopathy that might benefit from therapeutic hypothermia and to determine the efficacy of other adjunctive neuroprotective strategies. This review focuses on newer evidence and advances in diagnoses and management of infants with neonatal encephalopathy, including novel therapies, as well as prognostication of outcomes to childhood.

OBJECTIVE: To determine longitudinal measurements of resting energy expenditure (REE) by indirect calorimetry (IC) in healthy term infants during the first 2 months of life. STUDY DESIGN/METHODS:) with IC in a respiratory and metabolic steady state. RESULTS:production measurements were 9.3 ± 2.0 and 7.7 ± 1.2 mL/kg/min and 8.1 ± 2.2 and 6.4 ± 1.1 mL/kg/min at 1 and 2 months of age, respectively. CONCLUSION/CONCLUSIONS: This pilot study demonstrates longitudinal measurements of REE by IC in healthy term infants during the first 2 months of life. We also demonstrate that, overall, there is consistency in REE values in this population, with a likely decrease in individual longitudinal measurements over the first 2 months of life.

Congenital diaphragmatic hernia (CDH) in neonates may occur as an isolated finding, in association with other anomalies, or as part of a genetic syndrome. We report the first case of an infant with CDH who presented with hyponatremic seizures due to adrenal hypoplasia congenita (AHC). The patient underwent repair of CDH defect. After an uncomplicated postoperative course while on discharge planning, he developed a seizure episode associated with severe hyponatremia and hyperkalemia. Extensive diagnostic workup revealed an NR0B1 gene variant confirming the diagnosis of X-linked AHC. The patient was eventually discharged home on hydrocortisone, fludrocortisone, and salt supplements. There are a few case reports of adrenal insufficiency in neonates with CDH, manifesting with symptoms before and immediately after reparative surgery. Clinical presentation of our patient was unique in manifesting as neonatal seizure secondary to severe hyponatremia after a stable postoperative phase. The patient's electrolytes and hemodynamic status remained stable before, during, and after surgery for CDH. This case underlines the importance of taking detailed family history and continued vigilance for signs and symptoms of adrenal insufficiency in infants with repaired CDH by pediatricians and intensivists.

Background Maternal chorioamnionitis is a risk factor for sepsis but, often, these infants are asymptomatic at birth. Different markers for infections, such as the immature to total (I/T) white blood cell (WBC) ratio, are used to help determine which infants require lumbar punctures (LPs), in addition to blood cultures and antibiotics. The timing of when the complete blood count (CBC) is obtained may have some effect on the length of antibiotic treatment. Aims The purpose of this proof-of-concept study was to assess if obtaining a CBC at greater than four hours of life as compared to less than four hours of life has an impact on the incidence of LPs performed in asymptomatic, full-term infants undergoing evaluation for sepsis secondary to maternal chorioamnionitis. Methods We performed a retrospective study of full-term, asymptomatic infants admitted for sepsis evaluation secondary to maternal chorioamnionitis. Subjects were grouped based upon the timing of their initial CBC (early = < four hours of life or late = > four hours of life). The incidence of LPs, duration of antibiotic treatment, and length of hospitalization were compared between the groups. Results A total of 230 subjects were included in the study (early group = 124, late group = 106). Subjects in the late group underwent significantly fewer LPs than subjects in the early group, 5.7% vs. 22.6% (p<0.001). There was no difference in length of treatment or hospitalization. Conclusions Asymptomatic full-term infants undergoing evaluation for sepsis secondary to maternal chorioamnionitis are less likely to undergo an LP if their initial CBC is obtained at greater than four hours of life.

Introduction/Aim: Our Pediatric ECMO Program was launched in March of 2015. Based on historical volumes and projections we anticipated a low volume center. Per ELSO Guidelines, ECMO centers require institutional structure and organization for effective use of ECMO therapy. Also, literature review of pediatric ECMO patient outcomes imply that high volume ECMO centers are associated with improved survival rates in pediatric ECMO patients. Our goal was to implement a formal Pediatric ECMO Program, along with a structured educational course, to demonstrate that successful patient survival rates are obtainable in a low volume ECMO center. Material and Methods: A comprehensive review was completed to identify gaps and areas for improvement within the current state of ECMO at the institution with the goal of establishing an ECMO Program, per ELSO Guidelines, that ensures safe use of ECMO, improved patient outcomes, and optimized programmatic processes. Interventions implemented to formalize the ECMO Program included establishment of clinical practice guidelines and protocols, creation of an ECMO credentialing process, standardization of intrahospital processes related to ECMO, and organization of patient data collection. To assure reasonable use of this resource all cannulation and decannulation decisions required agreement of both the Medical and Surgical ECMO Directors. Formalization of the interprofessional collaboration with the critical care teams and ancillary departments was established with structured morning and evening rounds. Collaboration continued through implementation of formal multidisciplinary team meetings, including patient case reviews and quality assurance meetings. Last, a primary intervention in formalization of an ECMO Program was the establishment of an ECMO education course that was required for all providers who would be involved in the care of ECMO patients. The course was geared towards frontline critical care physicians and advanced practice providers caring for pediatric ECMO patients. The course included didactic learning and simulation training with a high fidelity simulation mannequin and a running ECMO circuit. Pre-and postcourse, participants completed self-assessments and knowledge tests. Results: Since March 2015, our Pediatric ECMO Program averages 5 ECMO patients per fiscal year (September 1 to August 31). In the first fiscal year (FY) 2015, our survival from ECMO rate was 33% with 0% of our patients surviving to discharge. Our hemorrhagic and neurologic complication rates were 67%. The formalization of our ECMO Program and implementation of ECMO education occurred in April 2016, mid FY 2016. Our survival from ECMO rate for FY 2016 improved from 33% to 86%, showing a 160.6% increase. Subsequently, our survival from ECMO rates continued to improve with FY 2017 having 100% survival rate and FY 2018 having 80% survival rate. We also observed a notable decrease in hemorrhagic and neurologic complications per FY. These complications decreased by 40.3% and 70.1%, respectively. Along with tracking our ECMO patient outcomes and complications, our program closely monitors our ECMO consults. Since March 2015, we average 23 ECMO consults per FY with an average of 5 patients (20%) placed on ECMO and 18 patients (80%) denied from ECMO. Out of the patients who were denied ECMO support, 30% of patients expired and 70% of patients recovered and survived to discharge, emphasizing the importance of strict patient selection criteria and centralized ECMO decision-making. For our ECMO course results, our team has held seven courses since August 2016. Among the first time participants (n=82), 84% showed improvement, 10% did worse, and 6% had incomplete data in their post-test written knowledge test. Conclusions: Despite a low institutional case volume of ECMO patients, creation of a structured ECMO Program with a recurring comprehensive ECMO course, promotes both self-confidence and clinical abilities of the multidisciplinary critical care team, as well as improves patient outcomes. Ongoing data collection and quality improvement will be essential to maintain this high level of performance
