Exclusive Breastfeeding in the Bronx-Successes and Shortcomings.

OBJECTIVE: Despite efforts to encourage breastfeeding, exclusive breastfeeding (EBF) rates in the Bronx remain suboptimal. Hospital restrictions and uncertainty surrounding the side effects of coronavirus disease 2019 (COVID-19) greatly impacted the mother-infant dyad during the postpartum hospitalization. Preliminary studies found an initial decrease in EBF, but lasting effects remain unknown. This study aimed to investigate the effect of the COVID-19 pandemic on birth hospitalization EBF rates among a high-risk urban patient population. STUDY DESIGN: A retrospective chart review was conducted on all newborns admitted to the newborn nursery at an urban medical center between 2019 and 2021. Patients were separated into prepandemic and pandemic cohorts. Patient demographics, maternal comorbidities, length of stay, feeding method, and newborn characteristics, including status as high risk for hypoglycemia, were collected. EBF was defined as receiving only mother's milk during the birth hospitalization. Descriptive statistics and bivariate analysis were used to examine the data. RESULTS: A total of 630 prepandemic and 643 pandemic newborns were included. The cohorts did not differ in baseline maternal characteristics. Prepandemic newborns were less likely to be high risk (23.3 vs. 29.4%, p = 0.01), more likely to see the hospital lactation consultant (53.2 vs. 24.0%, p < 0.001), and had a longer average length of stay (63.4 vs. 54.5 hours, p < 0.001). Most infants in both cohorts received some breastmilk during the hospitalization (97.6 vs. 94.6%, not significant). There was no difference in EBF between cohorts among all newborns (9.5 vs. 11.4%, p = 0.29) or among nonhigh-risk newborns (12.2 vs. 15.0%, p = 0.22). CONCLUSION: EBF rates in the Bronx, NY did not change during the pandemic period, despite an increase in high-risk newborns. Further investigation into the effect of lactation consultation, maternal race, ethnicity, and primary language should be further explored to understand the implications of health care disparities on the mother-infant dyad. KEY POINTS: · The COVID-19 pandemic disrupted many aspects of the mother-infant dyad.. · EBF rates at an urban institution in the Bronx did not change during the COVID-19 pandemic.. · Further investigation is warranted to better understand the barriers to EBF in this population..

Umbilical cord management - the first opportunity to improve healthcare disparities.

This review focuses on iron deficiency and iron deficiency anemia in women and children in the United States. These are common, fixable problems that disproportionally affect minority populations. There are many opportunities for successful screening and management. The knowledge and awareness for identification and treatment of our populations' commonest deficiency is crucial.

Decreasing the Newborn Birth Hospitalization Length of Stay.

OBJECTIVES: This study aimed to determine our ability to shorten birth hospitalization length of stay (LOS) in which patient characteristics were associated with early discharge and had effects on early newborn readmission rate. STUDY DESIGN: Retrospective chart review of births from April 1, 2020 to December 31, 2020, was considered for this study. Delivery mode and maternal and newborn characteristics were evaluated for effect on discharge timing. Hospital readmissions within 7 days of discharge were reviewed. RESULTS: In total, 845 out of 1,077 total live births were included in the study population. Five hundred and eighty-nine (69.7%) newborns were discharged early (<48 hours after vaginal delivery [VD] and <72 hours after cesarean delivery [CS]). Factors associated with early discharge included 79.8% CS (p < 0.001), 84% birth after 2 p.m. (p < 0.001), 71.2% no diagnosis of maternal diabetes (p = 0.02), and 70.6% negative maternal coronavirus disease 2019 (p = 0.01). The overall 7-day readmission rate was 1.2 and 0.5% for newborns discharged early after VD. CONCLUSION: Most newborns can be discharged early without increasing newborn readmission. KEY POINTS: · Most patients were discharged <72 hours after CS.. · Most patients were discharged <48 hours after VD.. · Early discharge does not affect newborn readmissions..

A Questionnaire Assessing Utilization of Delayed Cord Clamping.

OBJECTIVE: The study aimed to assess the practice of delayed cord clamping (DCC) and the awareness of its benefits for newborns between Obstetric (OB) and neonatal physicians. We examined if provider characteristics including years of experience, level of training, familiarity of the American College of Obstetricians and Gynecologists (ACOG)/American Academy of Pediatrics (AAP) recommendations, institutional policy, and the racial and ethnic background of patient population were associated with implementation of DCC. STUDY DESIGN: This research is a cross-sectional online questionnaire study. RESULTS: 975 questionnaires were returned. Overall, the awareness of ACOG versus AAP recommendations was 94 versus 86% (p < 0.01). 86 versus 78% of OB and neonatal physicians practiced or witnessed DCC >50% of the time, respectively (p < 0.01). An equal number of OB and neonatal physicians believed in the benefits to newborns of DCC. Physicians with >10 years of practice were less likely to acknowledge DCC benefits. Physicians with a majority of non-White patients were less likely to practice/witness DCC (p < 0.05). CONCLUSION: There continues to be room for improvement in the practice of DCC. Institutional policies and awareness of ACOG/AAP recommendations impact the understanding of the benefits of DCC and the likelihood of the practice. There is a significant difference in the practice of DCC among patients with different racial backgrounds. Hospital leadership may consider investing in the education and implementation of updated guidelines to ensure DCC is routinely practiced. KEY POINTS: · Knowledge of AAP/ACOG and institutional policies improved the practice of DCC.. · There is racial disparity in the practice of DCC.. · Physicians in practice for >10 years were less likely to know the benefits of DCC to full-term neonates..

Acute Otitis Media in an Extremely Preterm Infant.

There are a limited number of documented cases of acute otitis media (AOM) in preterm infants while hospitalized in the neonatal intensive care unit (NICU). We present a case of a former 26 weeks old infant who at 29 weeks, 6 days postmenstrual age presented with acute signs and symptoms of systemic sepsis subsequently found to be secondary to AOM with purulent ear drainage. The patient received a septic evaluation, including urine, blood, and cerebrospinal fluid studies. Treatment included intravenous antibiotics with full resolution of symptoms. AOM in extreme preterm infants is multifactorial, with leading causes that include prematurity, the use of oropharyngeal and nasogastric tube placement and endotracheal intubation, eustachian tube dysfunction, and a distinct immune response. To our knowledge, there is not another published case of AOM of a preterm baby while in the NICU.

Early Extended Neonatal Screening for Congenital Cytomegalovirus Infection: A Quality Improvement Initiative.

BACKGROUND: Identification of congenital cytomegalovirus (cCMV) infection in neonates is important for early diagnosis of sensorineural hearing loss. Therefore, a quality improvement project was designed with an aim to improve newborn CMV screening by 25% from a baseline rate of 22%. METHODS: This project was conducted across two hospital sites at one medical center with two tertiary care newborn nurseries and neonatal intensive care units. Symptomatic neonates with suggestive findings of cCMV, who had failed the newborn hearing screen, who had not had a hearing screen performed by 10 days of age, or who were infants of HIV-positive mothers were screened for cCMV. Serial interventions (formalized teaching sessions using an algorithm and involving a nurse educator, creation of electronic medical record order sets, huddle board reminders, and regular audits) were conducted, and statistical process control p-charts were used to identify any signals and to determine if there was any special cause variation. RESULTS: Of 5,817 infants born in 2018, 903 were eligible for screening. Small for gestational age (46%) was the most common indication for screening. After multiple interventions, the median screening rate increased from a baseline of 22% in 2016 to 74% during the one-year study period. Four infants had positive CMV screen and received appropriate treatment as a result of these interventions. CONCLUSION: Multidisciplinary quality improvement initiatives can improve newborn screening for cCMV infection in a tertiary care environment.

Patterned frequency-modulated oral stimulation in preterm infants: A multicenter randomized controlled trial.

OBJECTIVE: To evaluate the effect of patterned, frequency-modulated oro-somatosensory stimulation on time to full oral feeds in preterm infants born 26-30 weeks gestation. STUDY DESIGN: This is a multicenter randomized controlled trial. The experimental group (n = 109) received patterned, frequency-modulated oral stimulation via the NTrainer system through a pulsatile pacifier and the control group (n = 101) received a non-pulsatile pacifier. Intent-to-treat analysis (n = 210) was performed to compare the experimental and control groups and the outcomes were analyzed using generalized estimating equations. Time-to-event analyses for time to reach full oral feeds and length of hospital stay were conducted using Cox proportional hazards models. RESULTS: The experimental group had reduction in time to full oral feeds compared to the control group (-4.1 days, HR 1.37 (1.03, 1.82) p = 0.03). In the 29-30 weeks subgroup, infants in the experimental group had a significant reduction in time to discharge (-10 days, HR 1.87 (1.23, 2.84) p < 0.01). This difference was not observed in the 26-28 weeks subgroup. There was no difference in growth, mortality or morbidities between the two groups. CONCLUSIONS: Patterned, frequency-modulated oro-somatosensory stimulation improves feeding development in premature infants and reduces their length of hospitalization. TRIAL REGISTRATION: ClinicalTrials.gov NCT01158391.

Discrepancies in Radiograph Interpretation Between Pediatric Radiologists and Pediatric Intensivists in the Pediatric or Neonatal Intensive Care Unit.

BACKGROUND: In pediatric intensive care units (PICUs) and neonatal intensive care units (NICUs), patient management decisions are sometimes based on preliminary interpretations of radiographs by pediatric intensivists (PIs) before a formal interpretation by a pediatric radiologist (PR). OBJECTIVE: To quantify and classify discrepancies in radiographic interpretation between PRs and PIs in the PICU and NICU. MATERIALS AND METHODS: This institutional review board-approved multi-institutional prospective study included three PRs and PIs at two PICUs and three NICUs. Interpretations of chest and abdominal radiographs by PIs and PRs were recorded on online forms and compared. Discrepancies in interpretations were classified as "miss," "misinterpretation," or "overcall." The discrepancies were also categorized as "actionable" or "nonactionable" based on extrapolation of the ACR actionable reporting work group's list of actionable findings. RESULTS: In 960 radiographic interpretations, the total, nonactionable, and actionable discrepancy rates between PRs and PIs were 34.7%, 26.8%, and 7.9%, respectively. The most common actionable discrepancies were line or tube positions and identification and interpretation of parenchymal opacities in the lungs. Identification of air leaks in the PICU and differentiation of normal from abnormal bowel gas patterns in the NICU followed in frequency. Air leaks accounted for 1% of total discrepancies and 11% of actionable discrepancies. Most discrepancies were nonactionable and included retrocardiac atelectasis and mischaracterization of neonatal lung disease in the PICU and NICU, respectively. CONCLUSION: Although the total discrepancy rate was high, most discrepancies were nonactionable. Actionable discrepancies were predominantly due to line and tube position, which should be an area of focused education.

Sustained Improvement in Administration of the Hepatitis B Vaccine Birth Dose: A Quality Improvement Initiative.

The New York State Department of Health recommends the administration of the hepatitis B vaccine birth dose within 12 hours of life (HOL) for all full-term babies irrespective of maternal hepatitis B status. The primary and secondary aims of the project were to improve the timeliness of vaccine administration and increase the total number of infants vaccinated prior to discharge. Multiple Plan-Do-Study-Act cycles were performed. Statistical process charts of percentages of vaccination within 12 HOL and prior to discharge were constructed with 3-σ (data within 3 standard deviations from a mean) control limits. These control limits were adjusted after achieving significant improvements in performance over time. Administration within 12 HOL improved from 13% to ≥65% within 6 months, and has been sustained for >1 year. Vaccine administration prior to discharge increased from 94% to 98%. Quality improvement methods can rapidly improve adherence to newborn vaccine recommendations and these effects are sustainable.

Is urinary neutrophil gelatinase-associated lipocalin able to predict acute kidney injury episodes in very low birth weight infants in clinical settings?

BACKGROUND: We evaluated the potential utility of elevated urinary neutrophil gelatinase-associated lipocalin (UNGAL) concentration as a screening test for early identification of acute kidney injury (AKI) in very low birth weight (VLBW) newborns. METHODS: Urine for UNGAL analysis was collected prospectively daily until 32 wk postmenstrual age in 91 VLBW newborns, yielding 2,899 specimens. UNGAL values > 50 ng/ml were considered elevated. AKI was defined as two or more consecutive elevations in s[Cr] above the 95th percentile adjusted for gestational age and chronological age within a 48 h period. We compared UNGAL values taken during the 5 d prior to AKI onset (pre-AKI) to values taken during non-AKI days. RESULTS: Overall, 15 episodes of AKI were identified in 13 infants. UNGAL was available in 44 pre-AKI days and 969 non-AKI days. UNGAL > 50 ng/ml occurred more often in pre-AKI days than in non-AKI days (risk ratio 3.48 (1.89, 6.40)). Positive and negative likelihood ratios were 1.92 (1.52, 2.41) and 0.52 (0.34, 0.78), respectively. CONCLUSION: Although UNGAL elevation > 50 ng/ml discriminates between pre-AKI and non-AKI days, high false positive and false negative rates limit utility as a screening test in VLBW newborns.

Urinary neutrophil gelatinase-associated lipocalin is a promising biomarker for late onset culture-positive sepsis in very low birth weight infants.

Need for the early identification of sepsis in very low birth weight (VLBW) infants has led to the search for reliable biomarkers. This study aims to determine whether urinary neutrophil gelatinase-associated lipocalin (uNGAL) rises in culture-positive sepsis and, if so, is elevated at the time sepsis is suspected. This is a prospective study of 91 VLBW infants whose urine was collected daily for uNGAL analysis. In 65 episodes of suspected sepsis, four groups were identified: a) culture-positive sepsis; b) single culture positive for Staphylococcus epidermidis; c) and d) negative culture with antibiotic treatment for >or=7 d and <7 d, respectively. Daily means of uNGAL of each group were estimated for comparison. Mean uNGAL in group A (179 ng/mL) was significantly elevated on the day blood culture was drawn (day 0) compared with the mean of healthy VLBW infants (6.5 ng/mL), and to the means in groups B, C, and D (p<0.05). In group A, mean uNGAL was significantly elevated on day 0 and daily for 5 days when compared with that of the day before culture (p<0.05 to <0.005). uNGAL shows promise as an early marker for culture-positive sepsis in VLBW infants.

Reference values of urinary neutrophil gelatinase-associated lipocalin in very low birth weight infants.

In very low birth weight (VLBW) infants, acute renal impairment (ARI) is common, but there is no consensus about criteria for its diagnosis. Neutrophil gelatinase-associated lipocalin (NGAL) is an early and sensitive indicator of renal impairment in experimental animals, children, and adults. Urinary NGAL (UNGAL) is detectable in VLBW infants; however, there is no reference range in this population. The objective of this study is to define the reference range for UNGAL in VLBW infants with no risk factors for acute renal impairment. UNGAL concentration was determined in urine samples collected from day of life (DOL) 4 through DOL 30 in 50 newborns with uncomplicated clinical courses, selected from a total of 145 prospectively enrolled appropriate for gestational age inborn VLBW premature infants. The birth weight and gestational age ranges were 790-1490 g and 26-33 wk, respectively. The median, 95th and 99th percentiles, and range of pooled UNGAL values were 5 ng/mL, 50 ng/mL, 120 ng/mL, and 2-150 ng/mL, respectively. Greater variability and higher quantile levels of UNGAL were observed in females versus males. In conclusion, a reference range for UNGAL in VLBW infants, similar to that in children and adults, has been established.

Reference range of urinary neutrophil gelatinase-associated lipocalin in very low-birth-weight infants: preliminary data.

We sought to determine the reference range for urinary neutrophil gelatinase-associated lipocalin (UNGAL) in very low-birth-weight (VLBW) infants with uncomplicated clinical courses. Samples of urine from 53 VLBW infants between 3 and 28 days of life were prospectively collected weekly for measurement of UNGAL. A subset of 22 infants with uncomplicated medical courses without risk factors for renal impairment was selected for study. Mean +/- standard deviation and range for birth weight and gestational age of study infants were 1156 +/- 191, 790 to 1440 g and 29 +/- 2, 27 to 33 weeks, respectively. The 95th and 99th percentiles for UNGAL concentration from this group of infants were 25 ng/mL and 75 ng/mL, respectively. Bootstrapped mean 95th and 99th percentile values and their standard errors and 95 percent confidence intervals in ng/mL were 33.1 +/- 13.0 (7.7, 58.6) and 67.5 +/- 15.1 (37.9, 97.1), respectively. These values fall within the adult reference range. UNGAL values were stable across the ranges of gestational and postnatal age of the study infants. A preliminary reference range for UNGAL in VLBW infants has been established. Further investigation with more frequent urine collections in a larger population of VLBW infants that includes those with birth weights < 750 g and gestational ages < 27 weeks is necessary to confirm this reference range.

The ductus arteriosus rarely requires treatment in infants > 1000 grams.

We sought to determine the rate of spontaneous closure of the ductus arteriosus (DA) in very-low-birth-weight infants. This prospective observational study included 65 infants whose birth weight (BW) < 1500 g. Echocardiograms were done on day of life (DOL) 3 and 7, weekly for the first month, and bimonthly until ligation, discharge, or death. Treatment was reserved for infants with heart failure, acute renal impairment, or those with significant persistent or escalating respiratory support. Chi-square tests, Student T tests, and logistic regression models were used to identify possible associations between spontaneous ductal closure by DOL 7 and predictor variables. Patterns of spontaneous DA closure over time were examined using Kaplan-Meier survival analysis. The DA closed spontaneously in 49% infants by DOL 7. Rates of spontaneous closure by DOL 7 differed significantly by BW strata: 67% for BW > 1000 g, 31% for BW 1000 g did not require intervention, and the DA closed spontaneously prior to discharge in 94%. In a logistic regression model, only BW > 1000 g and male gender were significantly associated with spontaneous closure by 1 week of life. The median time to spontaneous closure differed significantly between infants in the two BW strata: 7 days for > 1000 g versus 56 days for 1000 g BW is rarely indicated. In infants
