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 Home Oxygen Use and 1-Year Readmission among Infants Born Preterm with Bronchopulmonary Dysplasia Discharged from Children's Hospital Neonatal Intensive Care Units(Elsevier, 2020-05) Lagatta, Joanne; Murthy, Karna; Zaniletti, Isabella; Bourque, Stephanie; Engle, William; Rose, Rebecca; Ambalavanan, Namasivayam; Brousseau, David; Pediatrics, School of MedicineObjective: To determine associations between home oxygen use and 1-year readmissions for preterm infants with bronchopulmonary dysplasia (BPD) discharged from regional neonatal intensive care units. Study design: We performed a secondary analysis of the Children's Hospitals Neonatal Database, with readmission data via the Pediatric Hospital Information System and demographics using ZIP-code-linked census data. We included infants born <32 weeks of gestation with BPD, excluding those with anomalies and tracheostomies. Our primary outcome was readmission by 1 year corrected age; secondary outcomes included readmission duration, mortality, and readmission diagnosis-related group codes. A staged multivariable logistic regression was adjusted for center, clinical, and social risk factors; at each stage we included variables associated at P < .1 in bivariable analysis with home oxygen use or readmission. Results: Home oxygen was used in 1906 of 3574 infants (53%) in 22 neonatal intensive care units. Readmission occurred in 34%. Earlier gestational age, male sex, gastrostomy tube, surgical necrotizing enterocolitis, lower median income, nonprivate insurance, and shorter hospital-to-home distance were associated with readmission. Home oxygen was not associated with odds of readmission (OR, 1.2; 95% CI, 0.98-1.56), readmission duration, or mortality. Readmissions for infants with home oxygen were more often coded as BPD (16% vs 4%); readmissions for infants on room air were more often gastrointestinal (29% vs 22%; P < .001). Clinical risk factors explained 72% of center variance in readmission. Conclusions: Home oxygen use is not associated with readmission for infants with BPD in regional neonatal intensive care units. Center variation in home oxygen use does not impact readmission risk. Nonrespiratory problems are important contributors to readmission risk for infants with BPD.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 Medical and surgical interventions and outcomes for infants with trisomy 18 (T18) or trisomy 13 (T13) at children's hospitals neonatal intensive care units (NICUs)(Springer Nature, 2021) Acharya, Krishna; Leuthner, Steven R.; Zaniletti, Isabella; Niehaus, Jason Z.; Bishop, Christine E.; Coghill, Carl H.; Datta, Ankur; Dereddy, Narendra; DiGeronimo, Robert; Jackson, Laura; Ling, Con Yee; Matoba, Nana; Natarajan, Girija; Pritha Nayak, Sujir; Brown Schlegel, Amy; Seale, Jamie; Shah, Anita; Weiner, Julie; Williams, Helen O.; Wojcik, Monica H.; Fry, Jessica T.; Sullivan, Kevin; Palliative Care and Ethics Focus Group of the Children’s Hospital Neonatal Consortium (CHNC); Pediatrics, School of MedicineObjectives: To examine characteristics and outcomes of T18 and T13 infants receiving intensive surgical and medical treatment compared to those receiving non-intensive treatment in NICUs. Study design: Retrospective cohort of infants in the Children's Hospitals National Consortium (CHNC) from 2010 to 2016 categorized into three groups by treatment received: surgical, intensive medical, or non-intensive. Results: Among 467 infants admitted, 62% received intensive medical treatment; 27% received surgical treatment. The most common surgery was a gastrostomy tube. Survival in infants who received surgeries was 51%; intensive medical treatment was 30%, and non-intensive treatment was 72%. Infants receiving surgeries spent more time in the NICU and were more likely to receive oxygen and feeding support at discharge. Conclusions: Infants with T13 or T18 at CHNC NICUs represent a select group for whom parents may have desired more intensive treatment. Survival to NICU discharge was possible, and surviving infants had a longer hospital stay and needed more discharge supports.Item Plasma‐derived biomarkers of Alzheimer's disease and neuropsychiatric symptoms: A community‐based study(Wiley, 2023-07-30) Krell-Roesch, Janina; Zaniletti, Isabella; Syrjanen, Jeremy A.; Kremers, Walter K.; Algeciras-Schimnich, Alicia; Dage, Jeffrey L.; van Harten, Argonde C.; Fields, Julie A.; Knopman, David S.; Jack, Clifford R., Jr.; Petersen, Ronald C.; Vassilaki, Maria; Geda, Yonas E.; Neurology, School of MedicineIntroduction: We examined associations between plasma-derived biomarkers of Alzheimer's disease (AD) and neuropsychiatric symptoms (NPS) in community-dwelling older adults. Methods: Cross-sectional study involving 1005 persons ≥50 years of age (mean 74 years, 564 male, 118 cognitively impaired), who completed plasma-derived biomarker (amyloid beta 42 [Aβ42]/Aβ40, phosphorylated tau 181 [p-tau181], p-tau217, total tau [t-tau], neurofilament light [NfL]), and NPS assessment. Results: P-tau181 (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.41-3.00, p < 0.001), p-tau217 (OR 1.70, 95% CI 1.10-2.61, p = 0.016), and t-tau (OR 1.44, 95% CI 1.08-1.92, p = 0.012) were associated with appetite change. We also found that p-tau181 and p-tau217 were associated with increased symptoms of agitation (OR 1.93, 95% CI 1.20-3.11, p = 0.007 and OR 2.04, 95% CI 1.21-3.42, p = 0.007, respectively), and disinhibition (OR 2.39, 95% CI 1.45-3.93, p = 0.001 and OR 2.30, 95% CI 1.33-3.98, p = 0.003, respectively). Aβ42/Aβ40 and NfL were not associated with NPS. Conclusion: Higher plasma-derived p-tau181 and p-tau217 levels are associated with increased symptoms of appetite change, agitation, and disinhibition. These findings may support the validity of plasma tau biomarkers for predicting behavioral symptoms that often accompany cognitive impairment. Highlights: We studied 1005 community-dwelling persons aged ≥ 50 years. Higher plasma tau levels are associated with increased neuropsychiatric symptoms Aβ42/Aβ40 and NfL are not associated with neuropsychiatric symptoms. Clinicians should treat neuropsychiatric symptoms in persons with high plasma-derived tau.Item 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.
