RESUMEN
OBJECTIVES: The impact of exclusive human milk diet (EHMD) on postnatal growth remains controversial. This study aims to investigate the association between EHMD and short-term growth. METHODS: This multicenter retrospective study aims to compare growth between the EHMD and non-EHMD groups among infants <32 weeks of gestation. Primary outcomes include weight, length, and head circumference growth trajectories between birth and 34 weeks postmenstrual age. Sensitivity and subgroup analyses were performed. RESULTS: An EHMD was independently associated with poorer length growth, especially in infants born at ≥28 weeks' gestation or those exposed to hypertensive disorders of pregnancy. While initiating fortification at <26 kcal/oz on an EHMD showed inferior growth, initiating fortification at ≥26 kcal/oz was associated with improved weight growth, and similar length and head circumference growth when compared to the non-EHMD group. CONCLUSIONS: An EHMD with initial fortification at ≥26 kcal/oz may be implemented to avoid bovine milk exposure while sustaining comparable growth.
RESUMEN
Importance: Bronchopulmonary dysplasia (BPD) rates in the United States remain high and have changed little in the last decade. Objective: To develop a consistent BPD prevention bundle in a systematic approach to decrease BPD. Design, Setting, and Participants: This quality improvement study included 484 infants with birth weights from 501 to 1500 g admitted to a level 3 neonatal intensive care unit in the Kaiser Permanente Southern California system from 2009 through 2019. The study period was divided into 3 periods: 1, baseline (2009); 2, initial changes based on ongoing cycles of Plan-Do-Study-Act (2010-2014); and 3, full implementation of successive Plan-Do-Study-Act results (2015-2019). Interventions: A BPD prevention system of care bundle evolved with a shared mental model that BPD is avoidable. Main Outcomes and Measures: The primary outcome was BPD in infants with less than 33 weeks' gestational age (hereafter referred to as BPD <33). Other measures included adjusted BPD <33, BPD severity grade, and adjusted median postmenstrual age (PMA) at hospital discharge. Balancing measures were adjusted mortality and adjusted mortality or specified morbidities. Results: The study population included 484 infants with a mean (SD) birth weight of 1070 (277) g; a mean (SD) gestational age of 28.6 (2.9) weeks; 252 female infants (52.1%); and 61 Black infants (12.6%). During the 3 study periods, BPD <33 decreased from 9 of 29 patients (31.0%) to 3 of 184 patients (1.6%) (P < .001 for trend); special cause variation was observed. The standardized morbidity ratio for the adjusted BPD <33 decreased from 1.2 (95% CI, 0.7-1.9) in 2009 to 0.4 (95% CI, 0.2-0.8) in 2019. The rates of combined grades 1, 2, and 3 BPD decreased from 7 of 29 patients (24.1%) to 17 of 183 patients (9.3%) (P < .008 for trend). Grade 2 BPD rates decreased from 3 of 29 patients (10.3%) to 5 of 183 patients (2.7%) (P = .02 for trend). Adjusted median PMA at home discharge decreased by 2 weeks, from 38.2 (95% CI, 37.3-39.1) weeks in 2009 to 36.8 (95% CI, 36.6-37.1) weeks during the last 3 years (2017-2019) of the full implementation period. Adjusted mortality was unchanged, whereas adjusted mortality or specified morbidities decreased significantly. Conclusions and Relevance: A sustained low rate of BPD was observed in infants after the implementation of a detailed BPD system of care.

INTRODUCTION: Data on laboratory markers of spontaneous intestinal perforation (SIP) and necrotizing enterocolitis (NEC) remain sparse. OBJECTIVE: To compare serum alkaline phosphatase levels in infants with bowel perforation secondary to SIP versus surgical NEC, and then investigate the possible role of serum alkaline phosphatase in differentiating infants with these conditions. METHODS: A retrospective case-control study of infants admitted with bowel perforation from 2005 to 2015. Demographic and prenatal data, postnatal exposures, and clinical, laboratory, and radiographic findings were extracted from inpatient medical records and analyzed using regression analysis. RESULTS: Of 114 outborn infants included, 48 infants had SIP (cases) and 66 had NEC (controls). Upon admission from the referring hospital, the serum alkaline phosphatase level was significantly higher in infants with SIP, i.e., a median value of 782 versus236 U/L in NEC patients (p < 0.0001), with an adjusted odds ratio (OR) of 4.3 (p < 0.05) when the level was >500 U/L in multivariate regression model. Infants with SIP had significantly younger gestational age, presented earlier in life, primarily with pneumoperitoneum, and had greater exposure to steroids and indomethacin compared to infants with NEC. Alkaline phosphatase levels decreased rapidly in infants with SIP following admission. CONCLUSION: A transient increase in serum alkaline phosphatase level is independently associated with SIP when compared to NEC. Studies to confirm the role of alkaline phosphatase in the diagnosis of SIP are necessary and have potentially significant clinical and prognostic implications.

PURPOSE: Hepatobiliary scintigraphy (HBS) is used to aid in the diagnosis of Biliary Atresia in full-term infants with conjugated hyperbilirubinemia. There is little information on the utility of the HBS in premature infants with conjugated hyperbilirubinemia and infants with parenteral nutrition associated cholestasis (PNAC). The purpose of this study is to assess the utility of HBS in differentiating Biliary Atresia and PNAC in premature neonates and full-term infants who received parenteral nutrition (PN). MATERIALS AND METHODS: Retrospective data collection and analysis on infants who developed conjugated hyperbilirubinemia and had HBS performed during their stay at level IV neonatal intensive care unit between 2005 and 2015. RESULTS: A total of 20 patients with exposure to PN had HBS; two patients were confirmed to have Biliary Atresia. There were no statistically significant differences between patients with Biliary Atresia versus PNAC in demographics, days on PN, or gamma glutamyl-transferase levels. Stool color was statistically significantly different between the two groups; patients with Biliary Atresia had acholic stools more consistently than patients without Biliary Atresia. HBS had 100% sensitivity, 17% specificity, positive-predictive value of 12%, and a negative-predictive value (NPV) of 100%. CONCLUSIONS: These data indicate that the ability of HBS to aid in diagnosing Biliary Atresia is poor in a population of preterm neonates and full-term infants with PNAC. Although there is 100% sensitivity, the poor specificity (17%) should be acknowledged when utilizing HBS to diagnose Biliary Atresia in this vulnerable patient population. NPV of 100% is helpful in ruling out Biliary Atresia in this population.

OBJECTIVE: The purpose of this study was to determine the prevalence of preterm births in pregnancies complicated by fetal gastroschisis in our tertiary referral center. METHODS: We conducted a retrospective review of medical records of patients with fetal gastroschisis delivered at our institution between January 2004 and April 2012. RESULTS: A total of 63 patients met the study criteria. Of these, 32 (51 %) were delivered before 37 0/7 weeks of gestation. The mean estimated gestational age at delivery was 35 4/7 ± 1 week (range 32 6/7-36 6/7) weeks. Spontaneous preterm delivery occurred in 27 patients (43 %). The remaining 31 patients (49 %) delivered between 37 0/7 and 39 2/7 weeks of gestation. CONCLUSION: The majority of patients with fetal gastroschisis were delivered before 37 weeks of gestation with a significant proportion delivering due to spontaneous onset of preterm labor. In addition to antepartum surveillance for fetal well-being, monitoring patients for symptoms and signs of preterm labor is recommended.

OBJECTIVE: The purpose of our study was to determine whether fetal magnetic resonance imaging (MRI) provides additional information that might affect the obstetric management of pregnancies complicated by sonographically diagnosed fetal urinary tract anomalies. METHODS: Fetal MRI and sonography were used to study 39 women with suspected fetal urinary tract anomalies in the second and third trimesters of pregnancy. RESULTS: In 24 of 39 cases (61%), fetal MRI confirmed the sonographic diagnosis. In 14 cases (36%), fetal MRI modified the initial sonographic diagnosis and counseling but did not change obstetric management. In 1 case (3%), the addition of fetal MRI resulted in a substantial change in the management of the pregnancy. CONCLUSIONS: During the second and third trimesters of pregnancy, fetal MRI showed fetal urinary tract anomalies in excellent anatomic detail. Fetal MRI is a useful complementary tool in the assessment of sonographically diagnosed fetal urinary tract anomalies. In a small percentage of cases, it can have a substantial impact on obstetric management.
