Nayak, Amrita; Tiozzo, Caterina; Lin, Xinhua; Mejia, Claudia; Gurzenda, Ellen; Kim, Maureen; Hanna, Nazeeh
OBJECTIVE: Human milk (HM) has antibacterial properties due to the presence of immune-modulators, including lactoferrin (LF). This study will determine effect(s) of HM maturation, fortification, and storage conditions on LF levels and its antibacterial properties. STUDY DESIGN/METHODS:. RESULTS: The highest level of LF in preterm HM was observed in the first week of lactation. However, storage of preterm HM at 4°C decreased LF levels significantly. Both LF levels and antibacterial activity in preterm HM was lower compared with term HM, but significantly higher than donor HM even after HM-based fortification. LF supplementation of donor HM improved its antibacterial activity. CONCLUSION/CONCLUSIONS: Preterm infants fed donor HM, formula, or stored HM at 4°C may benefits from LF supplementation to improve HM antibacterial properties. KEY POINTS/CONCLUSIONS:· Milk LF levels vary with storage and maturity.. · Donor milk is deficient in LF even after adding HM-based fortification.. · Donor HM and formula fed infants may benefit from LF..

A Quality Improvement Intervention to Decrease Hypothermia in the Delivery Room Using a Checklist

Vinci, Alexandra; Islam, Shahidul; Quintos-Alegheband, Lyn; Hanna, Nazeeh; Nayak, Amrita
Introduction/UNASSIGNED:Premature babies are at increased risk of hypothermia, core body temperature <97°F. Delivery room environment may contribute and lead to complications. The objective was to reduce hypothermia in babies <32 weeks of gestation in the delivery room to <40% using a checklist and sustain it for 6 months. Methods/UNASSIGNED:We created a delivery room checklist in 2012. Chart review established a baseline rate of hypothermia (<97°F). The team analyzed the checklist's effect on hypothermia from 2012 to 2018 and utilized numerous interventions to maintain compliance. Chi-square test and Fisher's exact test analyzed hypothermia and hyperthermia as a balancing measure. All calculations performed in SAS 9.3. Results/UNASSIGNED:The checklist reduced hypothermia from a baseline of 50% in 2011 (n = 104) to 33% in 2012 (n = 106). In 2013, the proportion of hypothermia slightly increased to 36% (n = 81). The year 2014 brought larger drift, and proportion of hypothermia increased to 44% (n = 117). In 2015, we reinforced the use of the checklist and proportion of hypothermia improved to 36% (n = 99). Further interventions through 2018 decreased hypothermia further to 14% to achieve statistical significance. Conclusions/UNASSIGNED:A checklist is a simple tool that may yield beneficial changes in practice and helped to decrease the proportion of neonatal hypothermia.

A Quality Improvement Initiative to Improve Normothermia While Transitioning Premature Infants to an Open Crib

Campbell, Nadia; Han, Austin; Kamity, Ranjith; Nayak, Amrita
INTRODUCTION/UNASSIGNED:Current literature focuses on the optimal lowest weight and incubator temperature to transition an infant to an open crib, with minimal data quantifying the rate of failed attempts or standardizing the process. Due to multiple failed attempts at this institution in 2021, the project aimed to reduce the rate of preterm newborns who failed the crib by 10% in 1 year. METHODS/UNASSIGNED:Interventions, including nursing education, an audit checklist, environmental changes, and a standardized protocol, were implemented after establishing baseline data. RESULTS/UNASSIGNED:The incidence of failed transitions to an open crib decreased from a baseline of 13.5% failed cribs per monthly transition attempts to 3.3% failed cribs per monthly transition attempts in 18 months, a 76% decrease, where it is currently sustained. Of note, infants born between 32 and 35 weeks gestation had higher failure rates compared with those born <32 weeks. CONCLUSIONS/UNASSIGNED:Compliance with a thermoregulation protocol, utilizing an audit checklist, and standardizing the process improved the success rate of transitioning to an open crib.

Biodistribution of mRNA COVID-19 vaccines in human breast milk

Hanna, Nazeeh; De Mejia, Claudia Manzano; Heffes-Doon, Ari; Lin, Xinhua; Botros, Bishoy; Gurzenda, Ellen; Clauss-Pascarelli, Christie; Nayak, Amrita
BACKGROUND:COVID-19 mRNA vaccines play a vital role in the fight against SARS-CoV-2 infection. However, lactating women have been largely excluded from most vaccine clinical trials. As a result, limited research has been conducted on the systemic distribution of vaccine mRNA during lactation and whether it is excreted in human breast milk (BM). Here, we evaluated if COVID-19 vaccine mRNA is detectable in BM after maternal vaccination and determined its potential translational activity. METHODS:We collected BM samples from 13 lactating, healthy, post-partum women before and after COVID-19 mRNA vaccination. Vaccine mRNA in whole BM and BM extracellular vesicles (EVs) was assayed using quantitative Droplet Digital PCR, and its integrity and translational activity were evaluated. FINDINGS/RESULTS:Of 13 lactating women receiving the vaccine (20 exposures), trace mRNA amounts were detected in 10 exposures up to 45 h post-vaccination. The mRNA was concentrated in the BM EVs; however, these EVs neither expressed SARS-COV-2 spike protein nor induced its expression in the HT-29 cell line. Linkage analysis suggests vaccine mRNA integrity was reduced to 12-25% in BM. INTERPRETATION/CONCLUSIONS:Our findings demonstrate that the COVID-19 vaccine mRNA is not confined to the injection site but spreads systemically and is packaged into BM EVs. However, as only trace quantities are present and a clear translational activity is absent, we believe breastfeeding post-vaccination is safe, especially 48 h after vaccination. Nevertheless, since the minimum mRNA vaccine dose to elicit an immune reaction in infants <6 months is unknown, a dialogue between a breastfeeding mother and her healthcare provider should address the benefit/risk considerations of breastfeeding in the first two days after maternal vaccination. FUNDING/BACKGROUND:This study was supported by the Department of Pediatrics, NYU-Grossman Long Island School of Medicine.

BACKGROUND:Baby-Friendly hospitals encourage rooming-in newborns with mothers. In our institution, we noticed increased incidence of hypothermia following Baby-Friendly designation. We aimed to reduce the incidence of hypothermia in the mother-baby-unit to <15% and to decrease the rate of isolated hypothermia admissions to the neonatal intensive care unit (NICU) by 20% over two years. METHODS:After a retrospective review of newborns ≥35 weeks gestation in the mother-baby-unit with hypothermia, we implemented multiple interventions such as nursing education, hypothermia algorithm, Kamishibai cards, and Key cards. RESULTS:Hypothermia incidence in the mother-baby-unit decreased from 20.9 to 14.5% (p < 0.001) and infants requiring NICU admission decreased by 71% (p < 0.001) following all interventions. Apart from nursing education, all interventions led to significant reductions in both outcomes from baseline. CONCLUSION/CONCLUSIONS:Instituting a hypothermia algorithm and utilizing K-cards and Key cards reduces the incidence of hypothermia in the mother-baby-unit and NICU admissions for isolated hypothermia.

Pneumothorax in Neonates Born to COVID-19-Positive Mothers: Fact or Fortuity? [Case Report]

Kamity, Ranjith; Nayak, Amrita; Dumpa, Vikramaditya
Neonates born to mothers with coronavirus disease 2019 (COVID-19) have been largely asymptomatic based on initial reports. All neonates born to mothers with COVID-19 have tested negative for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in our institution (published data as of April 12, 2020). As novel presentations of COVID-19, such as multisystem inflammatory syndrome in children are being increasingly reported, we raise the possibility of increased incidence of pneumothorax in neonates born to SARS-CoV-2-positive mothers. Two recently described neonates with COVID-19 infection were noted to have pneumothoraces. We describe two SARS-CoV-2-negative neonates born to COVID-19-positive mothers at 38 and 33 weeks, respectively, admitted to our neonatal intensive care unit for respiratory distress and subsequently developed pneumothoraces. As diverse clinical presentations in various age groups are being described, it becomes difficult to differentiate the increased incidence of complications related to an underlying illness, from COVID-19-related illness. It remains to be seen if neonates with in utero exposure to SARS-CoV-2 have an elevated inflammatory response with pneumonitis and exaggerated lung disease, similar to adult COVID-19 patients, due to in utero exposure.

A Quality Improvement Initiative to Improve Perioperative Hypothermia Rates in the NICU Utilizing Checklists

Hanna, Morcos; Htun, Zeyar; Islam, Shahidul; Hanna, Nazeeh; Kothari, Ulka; Nayak, Amrita
Premature infants are at high risk for heat loss. Infants undergoing surgical procedures outside of the neonatal intensive care unit have an increased risk of hypothermia. Hypothermia can lead to delayed recovery, hypoglycemia, metabolic acidosis, sepsis, and emotional stress for the parents. We aimed to reduce the incidence of hypothermia for infants undergoing surgical procedures from a baseline of 44.4% to less than 25% over 3 years (2016-2018) with the utilization of a checklist and education.
