Item ACTUAL AND PRESCRIBED ENERGY AND PROTEIN INTAKES FOR VERY LOW BIRTH WEIGHT INFANTS: AN OBSERVATIONAL STUDY(2012-10-11) Abel, Deborah Marie; Rickard, Karyl A.; Brady, Mary Sue; Engle, William A.; Ingram, David A.; Poindexter, Brenda B.Objectives: To determine (1) whether prescribed and delivered energy and protein intakes during the first two weeks of life met Ziegler’s estimated requirements for Very Low Birth Weight (VLBW) infants, (2) if actual energy during the first week of life correlated with time to regain birth weight and reach full enteral nutrition (EN) defined as 100 kcal/kg/day, (3) if growth velocity from time to reach full EN to 36 weeks’ postmenstrual age (PMA) met Ziegler’s estimated fetal growth velocity (16 g/kg/day), and (4) growth outcomes at 36 weeks’ PMA. Study design: Observational study of feeding, early nutrition and early growth of 40 VLBW infants ≤ 30 weeks GA at birth in three newborn intensive care units NICUs. Results: During the first week of life, the percentages of prescribed and delivered energy (69% [65 kcal/kg/day]) and protein (89% [3.1 g/kg/day]) were significantly less than theoretical estimated requirements. Delivered intakes were 15% less than prescribed because of numerous interruptions in delivery and medical complications. During the second week, the delivered intakes of energy (90% [86 kcal/kg/day]) and protein (102% [3.5 g/kg/day]) improved although the differences between prescribed and delivered were consistently 15%. Energy but not protein intake during the first week was significantly related to time to reach full EN. Neither energy nor protein intake significantly correlated with days to return to birth weight. The average growth velocity from the age that full EN was attained to 36 weeks’ PMA (15 g/kg/day) was significantly less than the theoretical estimated fetal growth velocity (16 g/kg/day) (p<0.03). A difference of 1 g/kg/day represents a total deficit of 42 - 54 grams over the course of a month. At 36 weeks’ PMA, 53% of the VLBW infants had extrauterine growth restriction, or EUGR (<10th percentile) on the Fenton growth grid and 34% had EUGR on the Lubchenco growth grid. Conclusions: The delivered nutrient intakes were consistently less than 15% of the prescribed intakes. Growth velocity between the age when full EN was achieved and 36 weeks’ PMA was 6.7% lower than Ziegler’s estimate. One-third to one-half of the infants have EUGR at 36 weeks’ PMA.Item Association of Time of First Corticosteroid Treatment with Bronchopulmonary Dysplasia in Preterm Infants(Wiley, 2021) Cuna, Alain; Lagatta, Joanne M.; Savani, Rashmin C.; Vyas-Read, Shilpa; Engle, William A.; Rose, Rebecca S.; DiGeronimo, Robert; Logan, J. Wells; Mikhael, Michel; Natarajan, Girija; Truog, William E.; Kielt, Matthew; Murthy, Karna; Zaniletti, Isabella; Lewis, Tamorah R.; Children’s Hospitals Neonatal Consortium (CHNC) Severe BPD Focus Group; Pediatrics, School of MedicineObjective: To evaluate the association between the time of first systemic corticosteroid initiation and bronchopulmonary dysplasia (BPD) in preterm infants. Study design: A multi-center retrospective cohort study from January 2010 to December 2016 using the Children's Hospitals Neonatal Database and Pediatric Health Information System database was conducted. The study population included preterm infants <32 weeks' gestation treated with systemic corticosteroids after 7 days of age and before 34 weeks' postmenstrual age. Stepwise multivariable logistic regression was used to assess the association between timing of corticosteroid initiation and the development of Grade 2 or 3 BPD as defined by the 2019 Neonatal Research Network criteria. Results: We identified 598 corticosteroid-treated infants (median gestational age 25 weeks, median birth weight 760 g). Of these, 47% (280 of 598) were first treated at 8-21 days, 25% (148 of 598) were first treated at 22-35 days, 14% (86 of 598) were first treated at 36-49 days, and 14% (84 of 598) were first treated at >50 days. Infants first treated at 36-49 days (aOR 2.0, 95% CI 1.1-3.7) and >50 days (aOR 1.9, 95% CI 1.04-3.3) had higher independent odds of developing Grade 2 or 3 BPD when compared to infants treated at 8-21 days after adjusting for birth characteristics, admission characteristics, center, and co-morbidities. Conclusions: Among preterm infants treated with systemic corticosteroids in routine clinical practice, later initiation of treatment was associated with a higher likelihood to develop Grade 2 or 3 BPD when compared to earlier treatment.Item The Impact of Pulmonary Hypertension in Preterm Infants with Severe Bronchopulmonary Dysplasia through 1 Year(Elsevier, 2018-12) Lagatta, Joanne M.; Hysinger, Erik B.; Zaniletti, Isabella; Wymore, Erica M.; Vyas-Read, Shilpa; Yallapragada, Sushmita; Nelin, Leif D.; Truog, William E.; Padula, Michael A.; Porta, Nicolas F. M.; Savani, Rashmin C.; Potoka, Karin P.; Kawut, Steven M.; DiGeronimo, Robert; Natarajan, Girija; Zhang, Huayan; Grover, Theresa R.; Engle, William A.; Murthy, Karna; Pediatrics, School of MedicineObjectives To assess the effect of pulmonary hypertension on neonatal intensive care unit mortality and hospital readmission through 1 year of corrected age in a large multicenter cohort of infants with severe bronchopulmonary dysplasia. Study design This was a multicenter, retrospective cohort study of 1677 infants born <32 weeks of gestation with severe bronchopulmonary dysplasia enrolled in the Children's Hospital Neonatal Consortium with records linked to the Pediatric Health Information System. Results Pulmonary hypertension occurred in 370 out of 1677 (22%) infants. During the neonatal admission, pulmonary hypertension was associated with mortality (OR 3.15, 95% CI 2.10-4.73, P < .001), ventilator support at 36 weeks of postmenstrual age (60% vs 40%, P < .001), duration of ventilation (72 IQR 30-124 vs 41 IQR 17-74 days, P < .001), and higher respiratory severity score (3.6 IQR 0.4-7.0 vs 0.8 IQR 0.3-3.3, P < .001). At discharge, pulmonary hypertension was associated with tracheostomy (27% vs 9%, P < .001), supplemental oxygen use (84% vs 61%, P < .001), and tube feeds (80% vs 46%, P < .001). Through 1 year of corrected age, pulmonary hypertension was associated with increased frequency of readmission (incidence rate ratio [IRR] = 1.38, 95% CI 1.18-1.63, P < .001). Conclusions Infants with severe bronchopulmonary dysplasia-associated pulmonary hypertension have increased morbidity and mortality through 1 year of corrected age. This highlights the need for improved diagnostic practices and prospective studies evaluating treatments for this high-risk population.Item Late Preterm and Early Term Birth: At-risk Populations and Targets for Reducing Such Early Births(AAP, 2017-05) Kardatzke, Matthew A.; Rose, Rebecca S.; Engle, William A.; Pediatrics, School of MedicineThe risks of late preterm (LPT) and early term (ET) birth have been recognized during the last decade. Increased awareness accompanied by efforts to reduce elective delivery before 39 weeks of gestation have led to a decline in LPT/ET births. Despite this success, strategies to identify and reduce preventable LPT/ET births using traditional and novel prevention methods are still needed. Because preterm birth is a common endpoint associated with many different preventable and nonpreventable causes, the efforts for reducing such early births must be multifaceted. For neonates born LPT/ET, there is an inverse relationship between gestational age and morbidity and mortality, with a nadir at 39 to 40 weeks of gestation. Recognition of the short-term complications of LPT/ET is important for timing of delivery and the initial clinical management of these patients. In addition, the recognition of the long-term respiratory and neurocognitive complications of LPT/ET birth helps inform the evaluation, treatment, and monitoring for impairments and disabilities that benefit from early detection and intervention. In this article, we review the definition of LPT/ET birth, prevention strategies, indications for LPT/ET birth, and the short- and long-term outcomes for such infants.Item Late Preterm Infants: Morbidities, Mortality, and Management Recommendations(Elsevier, 2019-04) Huff, Katie; Rose, Rebecca S.; Engle, William A.; Pediatrics, School of MedicineItem Utility of echocardiography in predicting mortality in infants with severe bronchopulmonary dysplasia(Springer Nature, 2019-09-30) Vyas-Read, Shilpa; Wymore, Erica M.; Zaniletti, Isabella; Murthy, Karna; Padula, Michael A.; Truog, William E.; Engle, William A.; Savani, Rashmin C.; Yallapragada, Sushmita; Logan, J. Wells; Zhang, Huayan; Hysinger, Erik B.; Grover, Theresa R.; Natarajan, Girija; Nelin, Leif D.; Porta, Nicolas F. M.; Potoka, Karin P.; DiGeronimo, Robert; Lagatta, Joanne M.; Children’s Hospitals Neonatal Consortium Severe BPD Focus Group; Pediatrics, School of MedicineObjective: To determine the relationship between interventricular septal position (SP) and right ventricular systolic pressure (RVSP) and mortality in infants with severe BPD (sBPD). Study design: Infants with sBPD in the Children's Hospitals Neonatal Database who had echocardiograms 34-44 weeks' postmenstrual age (PMA) were included. SP and RVSP were categorized normal, abnormal (flattened/bowed SP or RVSP > 40 mmHg) or missing. Results: Of 1157 infants, 115 infants (10%) died. Abnormal SP or RVSP increased mortality (SP 19% vs. 8% normal/missing, RVSP 20% vs. 9% normal/missing, both p < 0.01) in unadjusted and multivariable models, adjusted for significant covariates (SP OR 1.9, 95% CI 1.2-3.0; RVSP OR 2.2, 95% CI 1.1-4.7). Abnormal parameters had high specificity (SP 82%; RVSP 94%), and negative predictive value (SP 94%, NPV 91%) for mortality. Conclusions: Abnormal SP or RVSP is independently associated with mortality in sBPD infants. Negative predictive values distinguish infants most likely to survive.
