    Brain injury following trial of hypothermia for neonatal hypoxic–ischaemic encephalopathy
    (BMJ, 2012) Shankaran, Seetha; Barnes, Patrick D.; Hintz, Susan R.; Laptook, Abbott R.; Zaterka-Baxter, Kristin M.; McDonald, Scott A.; Ehrenkranz, Richard A.; Walsh, Michele C.; Tyson, Jon E.; Donovan, Edward F.; Goldberg, Ronald N.; Bara, Rebecca; Das, Abhik; Finer, Neil N.; Sanchez, Pablo J.; Poindexter, Brenda B.; Van Meurs, Krisa P.; Carlo, Waldemar A.; Stoll, Barbara J.; Duara, Shahnaz; Guillet, Ronnie; Higgins, Rosemary D.; Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network; Pediatrics, School of Medicine
    Objective: The objective of our study was to examine the relationship between brain injury and outcome following neonatal hypoxic-ischaemic encephalopathy treated with hypothermia. Design and patients: Neonatal MRI scans were evaluated in the National Institute of Child Health and Human Development (NICHD) randomised controlled trial of whole-body hypothermia and each infant was categorised based upon the pattern of brain injury on the MRI findings. Brain injury patterns were assessed as a marker of death or disability at 18-22 months of age. Results: Scans were obtained on 136 of 208 trial participants (65%); 73 in the hypothermia and 63 in the control group. Normal scans were noted in 38 of 73 infants (52%) in the hypothermia group and 22 of 63 infants (35%) in the control group. Infants in the hypothermia group had fewer areas of infarction (12%) compared to infants in the control group (22%). Fifty-one of the 136 infants died or had moderate or severe disability at 18 months. The brain injury pattern correlated with outcome of death or disability and with disability among survivors. Each point increase in the severity of the pattern of brain injury was independently associated with a twofold increase in the odds of death or disability. Conclusions: Fewer areas of infarction and a trend towards more normal scans were noted in brain MRI following whole-body hypothermia. Presence of the NICHD pattern of brain injury is a marker of death or moderate or severe disability at 18-22 months following hypothermia for neonatal encephalopathy.

    Preterm Neuroimaging and School-Age Cognitive Outcomes
    (American Academy of Pediatrics, 2018-07) Hintz, Susan R.; Vohr, Betty R.; Bann, Carla M.; Taylor, H. Gerry; Das, Abhik; Gustafson, Kathryn E.; Yolton, Kimberly; Watson, Victoria E.; Lowe, Jean; DeAnda, Maria Elena; Ball, M. Bethany; Finer, Neil N.; Van Meurs, Krisa P.; Shankaran, Seetha; Pappas, Athina; Barnes, Patrick D.; Bulas, Dorothy; Newman, Jamie E.; Wilson-Costello, Deanne E.; Heyne, Roy J.; Harmon, Heidi M.; Peralta-Carcelen, Myriam; Adams-Chapman, Ira; Duncan, Andrea Freeman; Fuller, Janell; Vaucher, Yvonne E.; Colaizy, Tarah T.; Winter, Sarah; McGowan, Elisabeth C.; Goldstein, Ricki F.; Higgins, Rosemary D.; Pediatrics, School of Medicine
    BACKGROUND AND OBJECTIVES: Children born extremely preterm are at risk for cognitive difficulties and disability. The relative prognostic value of neonatal brain MRI and cranial ultrasound (CUS) for school-age outcomes remains unclear. Our objectives were to relate near-term conventional brain MRI and early and late CUS to cognitive impairment and disability at 6 to 7 years among children born extremely preterm and assess prognostic value. METHODS: A prospective study of adverse early and late CUS and near-term conventional MRI findings to predict outcomes at 6 to 7 years including a full-scale IQ (FSIQ) <70 and disability (FSIQ <70, moderate-to-severe cerebral palsy, or severe vision or hearing impairment) in a subgroup of Surfactant Positive Airway Pressure and Pulse Oximetry Randomized Trial enrollees. Stepwise logistic regression evaluated associations of neuroimaging with outcomes, adjusting for perinatal-neonatal factors. RESULTS: A total of 386 children had follow-up. In unadjusted analyses, severity of white matter abnormality and cerebellar lesions on MRI and adverse CUS findings were associated with outcomes. In full regression models, both adverse late CUS findings (odds ratio [OR] 27.9; 95% confidence interval [CI] 6.0-129) and significant cerebellar lesions on MRI (OR 2.71; 95% CI 1.1-6.7) remained associated with disability, but only adverse late CUS findings (OR 20.1; 95% CI 3.6-111) were associated with FSIQ <70. Predictive accuracy of stepwise models was not substantially improved with the addition of neuroimaging. CONCLUSIONS: Severe but rare adverse late CUS findings were most strongly associated with cognitive impairment and disability at school age, and significant cerebellar lesions on MRI were associated with disability. Near-term conventional MRI did not substantively enhance prediction of severe early school-age outcomes.
