Abstract
BACKGROUND Late preterm infants are at high risk for medical complications and represent a growing NICU population. While 34-weeks' gestation infants are generally admitted to the NICU and 36-weeks'gestation infants stay in mother-baby, there is wide practice variation for 35-weeks'gestation infants. The objective of this study was to compare short-term outcomes of 35-weeks' gestation infants born at two hospitals within the same health system (DUHS), where one (DRH) admits all 35-weeks' gestation infants to their level II NICU and the other (DUH) admits all 35-weeks' gestation infants to mother-baby, unless clinical concern. METHODS We conducted a retrospective cohort analysis of 35-weeks' gestation infants born at DUHS from 2014-2019. Infant specific data were collected for birth, demographics, medications, medical therapies, LOS, ED visits and readmissions. 35-weeks' gestation infants at each hospital (DRH vs DUH) that met inclusion criteria were compared, regardless of unit(s) of care. RESULTS 726 infants of 35-weeks' gestation were identified, 591 met our inclusion criteria (DUH -462, DRH -129). Infants discharged from DRH were more likely to receive medical therapies (caffeine, antibiotics, blood culture, phototherapy, NGT), had a 4 day longer LOS, but were more likely to feed exclusively MBM at discharge. There were no differences in ED visits; however, more infants from DUH were readmitted within 30 days of discharge. CONCLUSIONS Our findings suggest admitting 35-weeks' gestation infants directly to the NICU increases medical interventions and LOS, but might reduce hospital readmissions.

Abstract
BACKGROUND There has been a 291% relative increase in congenital syphilis (CS) cases in the United States from 2015 to 2019. Although the majority of affected fetuses/infants are stillborn or are asymptomatic, a subset is born with severe clinical illness. We describe a series of severe CS cases in the neonatal intensive care unit. METHODS Retrospective review of infants with CS, admitted to the Duke Intensive Care Nursery from June 2016 to February 2020. We recorded birthweight, gestational age, medications, procedures, diagnoses, laboratory data and outcomes. Severe symptoms included: birth depression, hypoxic ischemic encephalopathy (HIE), disseminated intravascular coagulopathy and/or persistent pulmonary hypertension (PPHN). RESULTS Seven infants with CS were identified and 5 with severe presentations were included. Median gestational age was 35.1 weeks (range: 29-37 weeks, median: 35 weeks). All infants required intubation at birth, 2 required chest compressions and epinephrine in the delivery room. One had hydrops fetalis and died in the delivery room. All 4 surviving infants had HIE, severe PPHN, hepatitis and seizures. All infants had a positive rapid plasma reagin, and were treated with penicillin G. Maternal rapid plasma reagin was pending for 3 of 5 infants at delivery, and later returned positive; 2 were positive during pregnancy but not treated. Other infectious work-up was negative. Three infants survived to discharge. CONCLUSION CS can be associated with HIE, PPHN and disseminated intravascular coagulopathy in affected infants. Clinicians should have a high index of suspicion and include CS in their differential diagnoses. This study also highlights the importance of adequate treatment of identified cases and screening during the third trimester and at delivery.

Abstract
OBJECTIVE Very low birth weight preterm infants are at risk for life-threatening infections in the NICU. Breast milk protects against infections but carries the risk of infection by cytomegalovirus (CMV) shed in mother's milk. Lactoferrin is a breast milk and saliva protein with potent neutralizing activity against CMV. STUDY DESIGN VLBW, maternal breast milk fed infants in the NICU and their lactating mothers were enrolled and followed for 3 months/discharge. Breast milk and infant saliva samples were collected biweekly. Maternal CMV status was determined on breast milk. CMV was measured using quantitative polymerase chain reaction and lactoferrin by enzyme-linked immunosorbent assay. RESULTS In an in vitro neutralization assay, the IC90 of purified human lactoferrin against CMV was 2.08 ng/mL. Bovine lactoferrins were more potent, IC90s > 10-fold higher. Lactoferrin was detected in all breast milk (median: 3.3 × 106 ng/mL) and saliva (median: 84.4 ng/swab) samples. Median CMV load in breast milk was 893 copies/mL. There was no correlation between breast milk lactoferrin concentration and CMV load. Five infants acquired postnatal CMV. There was no difference in saliva or breast milk lactoferrin concentration for mother-infant pairs and postnatal CMV acquisition. CONCLUSION Lactoferrin neutralizes CMV in vitro, but concentrations in breast milk and saliva are likely too low for effective neutralization in vivo.

Abstract
BACKGROUND Randomized clinical trials have demonstrated that catheter ablation for atrial fibrillation in patients with heart failure with reduced ejection fraction may improve survival and other cardiovascular outcomes. METHODS We constructed a decision-analytic Markov model to estimate the costs and benefits of catheter ablation and medical management in patients with symptomatic heart failure with reduced ejection fraction (left ventricular ejection fraction ≤35%) and atrial fibrillation over a lifetime horizon. Evidence from the published literature informed the model inputs, including clinical effectiveness data from meta-analyses. Probabilistic and deterministic sensitivity analyses were performed. A 3% discount rate was applied to both future costs and benefits. The primary outcome was the incremental cost-effectiveness ratio assessed from the US health care sector perspective. RESULTS Catheter ablation was associated with 6.47 (95% CI, 5.89-6.93) quality-adjusted life years (QALYs) and a total cost of $105 657 (95% CI, $55 311-$191 934; 2018 US dollars), compared with 5.30 (95% CI, 5.20-5.39) QALYs and $63 040 (95% CI, $37 624-$102 260) for medical management. The incremental cost-effectiveness ratio for catheter ablation compared with medical management was $38 496 (95% CI, $5583-$117 510) per QALY gained. Model inputs with the greatest variation on incremental cost-effectiveness ratio estimates were the cost of ablation and the effect of catheter ablation on mortality reduction. When assuming a more conservative estimate of the treatment effect of catheter ablation on mortality (hazard ratio of 0.86), the estimated incremental cost-effectiveness ratio was $74 403 per QALY gained. At a willingness-to-pay threshold of $100 000 per QALY gained, atrial fibrillation ablation was found to be economically favorable compared with medical management in 95% of simulations. CONCLUSIONS Catheter ablation in patients with heart failure with reduced ejection fraction patients and atrial fibrillation may be considered economically attractive at current benchmarks for societal willingness-to-pay in the United States.

Abstract
IMPORTANCE Studies suggest that postnatal cytomegalovirus (CMV) infection can lead to long-term morbidity in infants with very low birth weight (VLBW; <1500 g), including bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), and neurodevelopmental impairment. However, to date, the association of postnatal CMV with hearing, growth, and length of stay among VLBW infants is unknown. OBJECTIVES To determine the risk for failed hearing screen, increased postnatal age at discharge, or decreased growth at discharge in VLBW infants with postnatal CMV infection compared with CMV-uninfected infants and to compare the risk for other major outcomes of prematurity, including BPD and NEC, in infants with and without postnatal CMV infection. PARTICIPANTS This multicenter retrospective cohort study included VLBW infants from 302 neonatal intensive care units managed by the Pediatrix Medical Group from January 1, 2002, through December 31, 2016. Infants hospitalized on postnatal day 21 with a diagnosis of postnatal CMV and hearing screen results after a postmenstrual age of 34 weeks were included in the study population. Data were analyzed from December 11, 2017, to June 14, 2019. MAIN OUTCOMES AND MEASURES Infants with and without postnatal CMV infection were matched using propensity scores. Poisson and linear regression were used to examine the association between postnatal CMV and the risk of failed hearing screen, postnatal age at discharge, growth, BPD, and NEC. RESULTS A total of 304 infants with postnatal CMV were identified, and 273 of these infants (89.8%; 155 boys [56.8%]) were matched with 273 infants without postnatal CMV (148 boys [54.2%]). Hearing screen failure occurred in 45 of 273 infants (16.5%) with postnatal CMV compared with 25 of 273 infants (9.2%) without postnatal CMV (risk ratio [RR], 1.80; 95% CI, 1.14 to 2.85; P = .01). Postnatal CMV was also associated with an increased postnatal age at discharge of 11.89 days (95% CI, 6.72 to 17.06 days; P < .001) and lower weight-for-age z score (-0.23; 95% CI, -0.39 to -0.07; P = .005). Analysis confirmed an increased risk of BPD (RR, 1.30; 95% CI, 1.17 to 1.44; P < .001), previously reported on infants from this cohort from 1997 to 2012, but not an increased risk of NEC after postnatal day 21 (RR, 2.00; 95% CI, 0.18 to 22.06; P = .57). CONCLUSIONS AND RELEVANCE These data suggest that postnatal CMV infection is associated with lasting sequelae in the hearing and growth status of VLBW infants and with prolonged hospitalization. Prospective studies are needed to determine the full effects of postnatal CMV infection and whether antiviral treatment reduces the associated morbidity.
