Objectives: To compare incidence of late-onset sepsis (LOS) among extremely preterm infants before and during the COVID-19 pandemic., Methods: Multicenter cohort study of infants with birthweight 401 to 1000 g or gestational age 22 to 28 weeks. LOS was defined as a bacterial or fungal pathogen isolated from blood or cerebrospinal fluid culture obtained after 72 hours of age. Primary outcome was LOS incidence calculated as incidence proportion (LOS cases among all admissions) and incidence rate (LOS events/1000 patient days). A multivariable Poisson regression model was used to compare the adjusted risk of LOS incidence proportion before (1/1/18-3/31/20) and during the pandemic (4/1/20-12/31/21). An interrupted time series analysis using a generalized linear mixed model with center as a random effect was used to compare LOS incidence rates during the 2 periods., Results: Among 6509 eligible infants, LOS incidence proportion was not different before (18.2%) and during the pandemic (16.9%; P = .18). The adjusted relative risk (95% CI) for LOS was 0.93 (0.82-1.05) and for LOS or mortality was 0.98 (0.88-1.08) during the pandemic compared to the period before the pandemic. In the interrupted time series analysis, there was no significant change in LOS incidence rates at the start of the pandemic (0.219, 95% CI, -0.453 to 0.891) or microbiology of LOS, and change in trends of LOS incidence rates before and during the pandemic was not significant (-0.005, 95% CI, -0.025 to 0.015)., Conclusions: In a large multicenter study of extremely preterm infants, rates of LOS remained unchanged during the pandemic., (Copyright © 2025 by the American Academy of Pediatrics.)

Objective: Assess if maternal betamethasone administration at 34-35 weeks accelerated neonatal amplitude integrated EEG (aEEG) maturation., Study Design: Nested, observational cohort in 7 centers participating in the Antenatal Late Preterm Steroid randomized trial. Up to 2 aEEGs were obtained in neonates born from 34 0 -35 6 weeks gestation before 72 h (aEEG 1) and at 5-7 days (aEEG 2) if hospitalized. Personnel and aEEG central readers were masked to the intervention. The primary outcome was maturation reflected by cycle frequency; secondary outcomes were border voltage, span, and discontinuity., Results: 58 neonates were enrolled (betamethasone, 28, placebo, 30). On aEEG 1, cycle frequency did not differ, but betamethasone exposed infants had a greater lower border voltage and a broader span. On aEEG 2, both groups displayed increases in lower border voltage., Conclusions: Betamethasone associated changes in lower border voltage support accelerated electrical activity. Further investigation is needed to understand the broader span., (© 2022. The Author(s), under exclusive licence to Springer Nature America, Inc.)

Resilience is having the ability to respond to adversity proactively and resourcefully. The coronavirus disease 2019 (COVID-19) pandemic's profound impact on antimicrobial stewardship programs (ASP) requires clinicians to call on their own resilience to manage the demands of the pandemic and the disruption of ASP activities. This article provides examples of ASP resilience from pharmacists and physicians from seven countries with different resources and approaches to ASP-The United States, The United Kingdom, Canada, Nigeria, Lebanon, South Africa, and Colombia. The lessons learned pertain to providing ASP clinical services in the context of a global pandemic, developing new ASP paradigms in the face of COVID-19, leveraging technology to extend the reach of ASP, and conducting international collaborative ASP research remotely. This article serves as an example of how resilience and global collaboration is sustaining our ASPs by sharing new "how to" do antimicrobial stewardship practices during the COVID-19 pandemic., Competing Interests: Debra A.

Objective: The aim of this study was to determine which initial surgical treatment results in the lowest rate of death or neurodevelopmental impairment (NDI) in premature infants with necrotizing enterocolitis (NEC) or isolated intestinal perforation (IP)., Summary Background Data: The impact of initial laparotomy versus peritoneal drainage for NEC or IP on the rate of death or NDI in extremely low birth weight infants is unknown., Methods: We conducted the largest feasible randomized trial in 20 US centers, comparing initial laparotomy versus peritoneal drainage. The primary outcome was a composite of death or NDI at 18 to 22 months corrected age, analyzed using prespecified frequentist and Bayesian approaches., Results: Of 992 eligible infants, 310 were randomized and 96% had primary outcome assessed. Death or NDI occurred in 69% of infants in the laparotomy group versus 70% with drainage [adjusted relative risk (aRR) 1.0; 95% confidence interval (CI): 0.87-1.14]. A preplanned analysis identified an interaction between preoperative diagnosis and treatment group (P = 0.03). With a preoperative diagnosis of NEC, death or NDI occurred in 69% after laparotomy versus 85% with drainage (aRR 0.81; 95% CI: 0.64-1.04). The Bayesian posterior probability that laparotomy was beneficial (risk difference <0) for a preoperative diagnosis of NEC was 97%. For preoperative diagnosis of IP, death or NDI occurred in 69% after laparotomy versus 63% with drainage (aRR, 1.11; 95% CI: 0.95-1.31); Bayesian probability of benefit with laparotomy = 18%., Conclusions: There was no overall difference in death or NDI rates at 18 to 22 months corrected age between initial laparotomy versus drainage. However, the preoperative diagnosis of NEC or IP modified the impact of initial treatment., Competing Interests: The authors report no conflict of interests., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objective: Determine risk of death or neurodevelopmental impairment (NDI) in infants with late-onset sepsis (LOS) versus late-onset, antibiotic-treated, blood culture-negative conditions (LOCNC)., Design: Retrospective cohort study., Setting: 24 neonatal centres., Patients: Infants born 1/1/2006-31/12/2014, at 22-26 weeks gestation, with birth weight 401-1000 g and surviving >7 days were included. Infants with early-onset sepsis, necrotising enterocolitis, intestinal perforation or both LOS and LOCNC were excluded., Exposures: LOS and LOCNC were defined as antibiotic administration for ≥5 days with and without a positive blood/cerebrospinal fluid culture, respectively. Infants with these diagnoses were also compared with infants with neither condition., Outcomes: Death or NDI was assessed at 18-26 months corrected age follow-up. Modified Poisson regression models were used to estimate relative risks adjusting for covariates occurring ≤7 days of age., Results: Of 7354 eligible infants, 3940 met inclusion criteria: 786 (20%) with LOS, 1601 (41%) with LOCNC and 1553 (39%) with neither. Infants with LOS had higher adjusted relative risk (95% CI) for death/NDI (1.14 (1.05 to 1.25)) and death before follow-up (1.71 (1.44 to 2.03)) than those with LOCNC. Among survivors, risk for NDI did not differ between the two groups (0.99 (0.86 to 1.13)) but was higher for LOCNC infants (1.17 (1.04 to 1.31)) compared with unaffected infants., Conclusions: Infants with LOS had higher risk of death, but not NDI, compared with infants with LOCNC. Surviving infants with LOCNC had higher risk of NDI compared with unaffected infants. Improving outcomes for infants with LOCNC requires study of the underlying conditions and the potential impact of antibiotic exposure., Competing Interests: Competing interests: RG has received support from industry for research services (https://dcri.org/about-us/conflict-of-interest/).

Objectives: The objectives describe the frequency that inadequate oral feeding (IOF) is the reason why moderately preterm (MPT) infants remain hospitalized and its association with neonatal morbidities., Study Design: Prospective study using the NICHD Neonatal Research Network MPT Registry. Multivariable logistic regression was used to describe associations between IOF and continued hospitalization at 36 weeks postmenstrual age (PMA)., Result: A total of 6017 MPT infants from 18 centers were included. Three-thousand three-seventy-six (56%) remained hospitalized at 36 weeks PMA, of whom 1262 (37%) remained hospitalized due to IOF. IOF was associated with RDS (OR 2.02, 1.66-2.46), PDA (OR 1.86, 1.37-2.52), sepsis (OR 2.36, 95% 1.48-3.78), NEC (OR 16.14, 7.27-35.90), and BPD (OR 3.65, 2.56-5.21) compared to infants discharged and was associated with medical NEC (OR 2.06, 1.19-3.56) and BPD (OR 0.46, 0.34-0.61) compared to infants remaining hospitalized for an alternative reason., Conclusion: IOF is the most common barrier to discharge in MPT infants, especially among those with neonatal morbidities.

Background/purpose: A non-standardized approach to caring for infants after pyloromyotomy for pyloric stenosis was associated with prolonged postoperative length of stay (pLOS) at our institution. We studied the impact of a standardized postoperative care protocol on pLOS, patients' clinical course, and nursing care., Methods: A retrospective chart review identified that 27% of infants who underwent uncomplicated pyloromyotomy had prolonged pLOS, defined as more than one postoperative midnight. A comprehensive postoperative care protocol was developed for infants undergoing pyloromyotomy. Patients were recruited prospectively and those with complications were excluded. A sample size of 70 in each cohort (historic and prospective) allowed 80% power to detect a 50% reduction in the proportion of patients with prolonged pLOS (α=0.05). The prospective group and historic cohort were compared using nonparametric statistics., Results: The historic cohort had 70 patients and the prospective cohort had 66. Protocol implementation resulted in fewer patients with prolonged pLOS, shorter time to feeds, fewer feeds to discharge, less emesis, and improved nursing documentation., Conclusion: Implementation of a postoperative care protocol improved various aspects of patient care and nursing care studied. Protocols outline a patient's course and serve as a common platform for communication among care providers; they can facilitate, expedite, and enhance patient care., (Copyright © 2015 Elsevier Inc.

Objective: Antenatal magnesium (anteMg) is used for various obstetric indications including fetal neuroprotection. Infants exposed to anteMg may be at risk for respiratory depression and delivery room (DR) resuscitation. The study objective was to compare the risk of acute cardiorespiratory events among preterm infants who were and were not exposed to anteMg., Study Design: This was a retrospective analysis of prospective data collected in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network's Generic Database from April 1, 2011, through March 31, 2012. The primary outcome was DR intubation or respiratory support at birth or on day 1 of life. Secondary outcomes were invasive mechanical ventilation, hypotension treatment, neonatal morbidities, and mortality. Logistic regression analysis evaluated the risk of primary outcome after adjustment for covariates., Results: We evaluated 1544 infants <29 weeks' gestational age (1091 in anteMg group and 453 in nonexposed group). Mothers in the anteMg group were more likely to have higher education, pregnancy-induced hypertension, and antenatal corticosteroids, while their infants were younger in gestation and weighed less (P < .05). The primary outcome (odds ratio [OR], 1.2; 95% confidence interval [CI], 0.88-1.65) was similar between groups. Hypotension treatment (OR, 0.70; 95% CI, 0.51-0.97) and invasive mechanical ventilation (OR, 0.54; 95% CI, 0.41-0.72) were significantly less in the anteMg group., Conclusion: Among preterm infants age <29 weeks' gestation, anteMg exposure was not associated with an increase in cardiorespiratory events in the early newborn period. The safety of anteMg as measured by the need for DR intubation or respiratory support on day 1 of life was comparable between groups., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Objective: The objective of this study was to characterize the incidence, management, and short-term outcomes of cardiovascular insufficiency (CVI) in mechanically ventilated newborns, evaluating four separate prespecified definitions., Study Design: Multicenter, prospective cohort study of infants ≥34 weeks gestational age (GA) and on mechanical ventilation during the first 72 hours. CVI was prospectively defined as either (1) mean arterial pressure (MAP) < GA; (2) MAP < GA + signs of inadequate perfusion; (3) any therapy for CVI; or (4) inotropic therapy. Short-term outcomes included death, days on ventilation, oxygen, and to full feedings and discharge., Results: Of 647 who met inclusion criteria, 419 (65%) met ≥1 definition of CVI. Of these, 98% received fluid boluses, 36% inotropes, and 17% corticosteroids. Of treated infants, 46% did not have CVI as defined by a MAP < GA ± signs of inadequate perfusion. Inotropic therapy was associated with increased mortality (11.1 vs. 1.3%; p < 0.05)., Conclusion: More than half of the infants met at least one definition of CVI. However, almost half of the treated infants met none of the definitions. Inotropic therapy was associated with increased mortality. These findings can help guide the design of future studies of CVI in newborns., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objectives: To evaluate the neurodevelopmental outcomes of very preterm (<30 weeks) infants who underwent tracheostomy., Study Design: Retrospective cohort study from 16 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network over 10 years (2001-2011). Infants who survived to at least 36 weeks (N = 8683), including 304 infants with tracheostomies, were studied. Primary outcome was death or neurodevelopmental impairment (NDI; a composite of ≥1 of developmental delay, neurologic impairment, profound hearing loss, severe visual impairment) at a corrected age of 18-22 months. Outcomes were compared using multiple logistic regression. We assessed the impact of timing by comparing outcomes of infants who underwent tracheostomy before and after 120 days of life., Results: Tracheostomies were associated with all neonatal morbidities examined and with most adverse neurodevelopmental outcomes. Death or NDI occurred in 83% of infants with tracheostomies and 40% of those without (OR adjusted for center 7.0, 95% CI 5.2-9.5). After adjustment for potential confounders, odds of death or NDI remained higher (OR 3.3, 95% CI 2.4-4.6), but odds of death alone were lower (OR 0.4, 95% CI 0.3-0.7) among infants with tracheostomies. Death or NDI was lower in infants who received their tracheostomies before, rather than after, 120 days of life (aOR 0.5, 95% CI 0.3-0.9)., Conclusions: Tracheostomy in preterm infants is associated with adverse developmental outcomes and cannot mitigate the significant risk associated with many complications of prematurity. These data may inform counseling about tracheostomy in this vulnerable population., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Congenital infections are those that are acquired transplacentally by the fetus from an infected mother. They constitute a major public health burden, affecting millions of infants and children worldwide. Despite significant advances in medical diagnostics, the majority of newborns with congenital infections are not recognized, since many of these infections may not cause clinically - apparent disease in the newborn period. Nonetheless, these infections - whether they are apparent or silent - have the potential to adversely impact the neurodevelopmental outcomes of these vulnerable children.
