Resting state functional MRI in infants with prenatal opioid exposure-a pilot study

PURPOSE: Exposure to prenatal opioids may adversely impact the developing brain networks. The aim of this pilot study was to evaluate alterations in amygdalar functional connectivity in human infants with prenatal opioid exposure. METHODS: In this prospective IRB approved study, we performed resting state functional MRI (rs-fMRI) in 10 infants with prenatal opioid exposure and 12 infants without prenatal drug exposure at < 48 weeks corrected gestational age. Following standard preprocessing, we performed seed-based functional connectivity analysis with the right and left amygdala as the regions of interest after correcting for maternal depression and infant sex. We compared functional connectivity of the amygdala network between infants with and without prenatal opioid exposure. RESULTS: There were significant differences in connectivity of the amygdala seed regions to the several cortical regions including the medial prefrontal cortex in infants who had prenatal opioid exposure when compared with opioid naïve infants. CONCLUSION: This finding of increased amygdala functional connectivity in infants with in utero opioid exposure suggests a potential role of maternal opioid exposure on infants' altered amygdala function. This association with prenatal exposure needs to be replicated in future larger studies

Cultural adaptation of the Bayley Scales of Infant and Toddler Development, 3rd Edition for use in Kenyan children aged 18-36 months: A psychometric study

Background: The Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) is frequently used in international child development research. No studies examine its psychometric properties when culturally adapted within the Kenyan context. Aims: To culturally adapt the Bayley-III for use in Kenya and evaluate its validity and reliability. Methods and procedures: Forward and backward translation, cognitive interviews, and a brief pilot of culturally adapted items were performed. This psychometric study was part of another study on children born to mothers with HIV in Eldoret, Kenya. One hundred seventy-two children aged 18-36 months were assessed for cognition, receptive/expressive communication, and fine/gross motor domains using the Bayley-III. Confirmatory factor analysis (CFA), inter-scale Pearson correlations, internal consistency, t-tests, and test-retest reliability were performed. Outcomes and results: The mean age of children was 22.8 (SD 4.5) months old; 52.7 % (n = 89) were male. CFA revealed that both two- and three-factor indices had good and comparable fit. Pearson correlations were high between fine motor and receptive communication (r \u3e0.70). Internal consistency was very strong for all of the subtests, with Cronbach coefficient alpha scores ranging from 0.88 to 0.96. Known groups/convergent validity was confirmed with stunting and parental concern for delays. Test-retest reliability was good and did not differ substantially across groups. Conclusions and implications: The Kenyan adapted Bayley-III is a psychometrically acceptable tool to assess child development. The scaled and composite scores should not be used to define Kenyan developmental norms, but it can be useful for comparing groups within research settings

Virtual Developmental Screening After Invasive Mechanical Ventilation in Children: A Prospective Cohort Pilot Study

OBJECTIVES: With decreasing PICU mortality, survivor morbidity has increased. This study aims to evaluate feasibility of virtual PICU-led follow-up of patients at risk for pediatric postintensive care syndrome. DESIGN: Prospective cohort study. SETTING: Single-center, quaternary children's hospital. PATIENTS: Children less than or equal to 4 years without known preexisting neurodevelopmental deficits requiring greater than or equal to 12 hours mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Age-appropriate Ages and Stages Questionnaires, Third Edition (ASQ-3) were administered via a web-based system at 3, 6, and 12 months following PICU discharge. Primary-care physicians were notified of results; at-risk patients were referred to early developmental intervention. Forty-eight patients enrolled with median age 11.5 months (interquartile range [IQR], 2-19.5 mo) and median mechanical ventilation duration 92.5 hours (IQR, 40.5-147 hr). Fifty-eight percent completed greater than or equal to 1 ASQ-3. Lower caregiver educational achievement, lower income, and single-caregiver status were associated with lower ASQ-3 completion rates. Of those completing any ASQ-3, 50% flagged as at-risk for developmental delay and referred to early developmental intervention. There was no association between patient characteristics and abnormal ASQ-3. CONCLUSIONS: Virtual caregiver-completed surveillance is a promising method to screen children for neurodevelopmental abnormalities following PICU hospitalization and facilitate early referral for developmental intervention, but special attention must be dedicated to families with limited resources for follow-up

Initial Laparotomy Versus Peritoneal Drainage in Extremely Low Birthweight Infants With Surgical Necrotizing Enterocolitis or Isolated Intestinal Perforation: A Multicenter Randomized Clinical Trial.

ObjectiveThe aim of this study was to determine which initial surgical treatment results in the lowest rate of death or neurodevelopmental impairment (NDI) in premature infants with necrotizing enterocolitis (NEC) or isolated intestinal perforation (IP).Summary background dataThe impact of initial laparotomy versus peritoneal drainage for NEC or IP on the rate of death or NDI in extremely low birth weight infants is unknown.MethodsWe conducted the largest feasible randomized trial in 20 US centers, comparing initial laparotomy versus peritoneal drainage. The primary outcome was a composite of death or NDI at 18 to 22 months corrected age, analyzed using prespecified frequentist and Bayesian approaches.ResultsOf 992 eligible infants, 310 were randomized and 96% had primary outcome assessed. Death or NDI occurred in 69% of infants in the laparotomy group versus 70% with drainage [adjusted relative risk (aRR) 1.0; 95% confidence interval (CI): 0.87-1.14]. A preplanned analysis identified an interaction between preoperative diagnosis and treatment group (P = 0.03). With a preoperative diagnosis of NEC, death or NDI occurred in 69% after laparotomy versus 85% with drainage (aRR 0.81; 95% CI: 0.64-1.04). The Bayesian posterior probability that laparotomy was beneficial (risk difference &lt;0) for a preoperative diagnosis of NEC was 97%. For preoperative diagnosis of IP, death or NDI occurred in 69% after laparotomy versus 63% with drainage (aRR, 1.11; 95% CI: 0.95-1.31); Bayesian probability of benefit with laparotomy = 18%.ConclusionsThere was no overall difference in death or NDI rates at 18 to 22 months corrected age between initial laparotomy versus drainage. However, the preoperative diagnosis of NEC or IP modified the impact of initial treatment
