    (Elsevier, 2014-06) DeMauro, Sara B.; D'Agostino, Jo Ann; Bann, Carla; Bernbaum, Judy; Gerdes, Marsha; Bell, Edward F.; Carlo, Waldemar A.; D'Angio, Carl; Das, Abhik; Higgins, Rosemary; Hintz, Susan R.; Laptook, Abbot R.; Natarajan, Girija; Nelin, Leif; Poindexter, Brenda B.; Sanchez, Pablo J.; Shankaran, Seetha; Stoll, Barbara J.; Truog, William; Van Meurs, Krisa P.; Vohr, Betty; Walsh, Michele C.; Kirpalani, Haresh; Department of Pediatrics, IU School of Medicine
    Objectives To evaluate the neurodevelopmental outcomes of very preterm (<30 weeks) infants who underwent tracheostomy. Study design Retrospective cohort study from 16 centers of the NICHD Neonatal Research Network over 10 years (2001-2011). Infants who survived to at least 36 weeks (N=8,683), including 304 infants with tracheostomies, were studied. Primary outcome was death or neurodevelopmental impairment (NDI, a composite of one or more of: developmental delay, neurologic impairment, profound hearing loss, severe visual impairment) at a corrected age of 18-22 months. Outcomes were compared using multiple logistic regression. We assessed impact of timing, by comparing outcomes of infants who underwent tracheostomy before and after 120 days of life. Results Tracheostomies were associated with all neonatal morbidities examined, and with most adverse neurodevelopmental outcomes. Death or NDI occurred in 83% of infants with tracheostomies and 40% of those without [odds ratio (OR) adjusted for center 7.0 (95%CI, 5.2-9.5)]. After adjustment for potential confounders, odds of death or NDI remained higher [OR 3.3 (95%CI, 2.4-4.6)], but odds of death alone were lower [OR 0.4 (95%CI, 0.3-0.7)], among infants with tracheostomies. Death or NDI was lower in infants who received their tracheostomies before, rather than after, 120 days of life [adjusted OR 0.5 (95%CI, 0.3-0.9)]. Conclusions Tracheostomy in preterm infants is associated with adverse developmental outcomes, and cannot mitigate the significant risk associated with many complications of prematurity. These data may inform counseling about tracheostomy in this vulnerable population.

    Limitations of Conventional Magnetic Resonance Imaging as a Predictor of Death or Disability Following Neonatal Hypoxic-Ischemic Encephalopathy in the Late Hypothermia Trial
    (Elsevier, 2021) Laptook, Abbot R.; Shankaran, Seetha; Barnes, Patrick; Rollins, Nancy; Do, Barbara T.; Parikh, Nehal A.; Hamrick, Shannon; Hintz, Susan R.; Tyson, Jon E.; Bell, Edward F.; Ambalavanan, Namasivayam; Goldberg, Ronald N.; Pappas, Athina; Huitema, Carolyn; Pedroza, Claudia; Chaudhary, Aasma S.; Hensman, Angelita M.; Das, Abhik; Wyckoff, Myra; Khan, Amir; Walsh, Michelle C.; Watterberg, Kristi L.; Faix, Roger; Truog, William; Guillet, Ronnie; Sokol, Gregory M.; Poindexter, Brenda B.; Higgins, Rosemary D.; Eunice Kennedy Shriver National Institute of Child Health; Human Development Neonatal Research Network; Pediatrics, School of Medicine
    Objective: To investigate if magnetic resonance imaging (MRI) is an accurate predictor for death or moderate-severe disability at 18-22 months of age among infants with neonatal encephalopathy in a trial of cooling initiated at 6-24 hours. Study design: Subgroup analysis of infants ≥36 weeks of gestation with moderate-severe neonatal encephalopathy randomized at 6-24 postnatal hours to hypothermia or usual care in a multicenter trial of late hypothermia. MRI scans were performed per each center's practice and interpreted by 2 central readers using the Eunice Kennedy Shriver National Institute of Child Health and Human Development injury score (6 levels, normal to hemispheric devastation). Neurodevelopmental outcomes were assessed at 18-22 months of age. Results: Of 168 enrollees, 128 had an interpretable MRI and were seen in follow-up (n = 119) or died (n = 9). MRI findings were predominantly acute injury and did not differ by cooling treatment. At 18-22 months, death or severe disability occurred in 20.3%. No infant had moderate disability. Agreement between central readers was moderate (weighted kappa 0.56, 95% CI 0.45-0.67). The adjusted odds of death or severe disability increased 3.7-fold (95% CI 1.8-7.9) for each increment of injury score. The area under the curve for severe MRI patterns to predict death or severe disability was 0.77 and the positive and negative predictive values were 36% and 100%, respectively. Conclusions: MRI injury scores were associated with neurodevelopmental outcome at 18-22 months among infants in the Late Hypothermia Trial. However, the results suggest caution when using qualitative interpretations of MRI images to provide prognostic information to families following perinatal hypoxia-ischemia.

    Ventilatory Strategies in Infants with Established Severe Bronchopulmonary Dysplasia: A Multicenter Point Prevalence Study
    (Elsevier, 2022) McKinney, Robin L.; Napolitano, Natalie; Levin, Jonathan J.; Kielt, Matthew J.; Abman, Steven H.; Cuevas Guaman, Milenka; Rose, Rebecca S.; Courtney, Sherry E.; Matlock, David; Agarwal, Amit; Leeman, Kristen T.; Sanlorenzo, Lauren A.; Sindelar, Richard; Collaco, Joseph M.; Baker, Christopher D.; Hannan, Kathleen E.; Douglass, Matthew; Eldredge, Laurie C.; Lai, Khanh; McGrath-Morrow, Sharon A.; Tracy, Michael C.; Truog, William; Lewis, Tamorah; Murillo, Anarina L.; Keszler, Martin; BPD Collaborative; Pediatrics, School of Medicine
    We performed a point prevalence study on infants with severe bronchopulmonary dysplasia (BPD), collecting data on type and settings of ventilatory support; 187 infants, 51% of whom were on invasive positive-pressure ventilation (IPPV), from 15 centers were included. We found a significant center-specific variation in ventilator modes.
