Neurodevelopmental outcome in one-year-old children born preterm: differences between low birth weight and very low birth weight

In preterm infants, low birth weight represents one of the major risk factors for health and developmental issues. In Italy, most of the studies are focused on extremely preterm or Very and Extremely Low Birth Weight (VLBW, ELBW) children, whereas little data are available on the neurodevelopmental outcome of Low Birth Weight (LBW) children. We aimed to study the developmental profile of a group of preterm children at 12 months of corrected age, comparing cognitive, language and motor performances between LBW and VLBW

Neurodevelopmental outcome of Italian preterm children at 1 year of corrected age by Bayley-III scales: an assessment using local norms

Background: Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III) constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is appropriate. Aims: This research aimed to examine neurodevelopment of preterm infants and full-term infants, using Bayley- III US norms in comparison to Italian (IT) norms. Patterns of developmental outcomes for both infant groups were also explored. Methods: 104 preterm and 58 full-term infants were included in the study. Bayley-III was used for neurodevelopmental assessment at 1 year of corrected age, considering both IT and US norms for scores computation. Results: Comparing scores obtained with IT vs US norms, differences in means were all significant across five subscales (p < 0.05 at least) for preterm infants, whereas for full-term peers significant differences were found only for Receptive Language and Fine Motor subscales (p < 0.001). Effect size (η2) ranged from 0.22 to 0.94. Within each group, significant discrepancies across subscales were found. Moreover, Italian preterm infants had significantly lower performances than full-term peers, excepting for Expressive Language and Gross Motor subscales. Conclusions: As regards to Italian 1-year children, our study seems to provide evidence for the tendency of Bayley-III US norms to overestimate development compared to IT norms. These findings emphasize the need to early detect children at risk for developmental delay and to plan early intervention

Pediatrician Adherence to Guidelines for Diagnosis and Management of High Blood Pressure

OBJECTIVES: To assess pediatrician adherence to the 2017 American Academy of Pediatrics\u27 clinical practice guideline for high blood pressure (BP). STUDY DESIGN: Pediatric primary care practices (n = 59) participating in a quality improvement collaborative submitted data for patients with high BP measured between November 2018 and January 2019. Baseline data included patient demographics, BP, body mass index (BMI), and actions taken. Logistic regression was used to test associations between patient BP level and BMI with provider adherence to guidelines (BP measurement, counseling, follow-up, evaluation). RESULTS: A total of 2677 patient charts were entered for analysis. Only 2% of patients had all BP measurement steps completed correctly, with fewer undergoing 3-limb and ambulatory BP measurement. Overall, 46% of patients received appropriate weight, nutrition, and lifestyle counseling. Follow-up for high BP was recommended or scheduled in 10% of encounters, and scheduled at the appropriate interval in 5%. For patients presenting with their third high BP measurement, 10% had an appropriate diagnosis documented, 2% had appropriate screening laboratory tests conducted, and none had a renal ultrasound performed. BMI was independently associated with increased odds of counseling, but higher BP was associated with lower odds of counseling. Higher BP was independently associated with an increased likelihood of documentation of hypertension. CONCLUSIONS: In this multisite study, adherence to the 2017 American Academy of Pediatrics\u27 guideline for high BP was low. Given the long-term health implications of high BP in childhood, it is important to improve primary care provider recognition and management. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03783650

Time to Peak Glucose and Peak C-Peptide During the Progression to Type 1 Diabetes in the Diabetes Prevention Trial and TrialNet Cohorts

OBJECTIVE To assess the progression of type 1 diabetes using time to peak glucose or C-peptide during oral glucose tolerance tests (OGTTs) in autoantibody-positive relatives of people with type 1 diabetes. RESEARCH DESIGN AND METHODS We examined 2-h OGTTs of participants in the Diabetes Prevention Trial Type 1 (DPT-1) and TrialNet Pathway to Prevention (PTP) studies. We included 706 DPT-1 participants (mean ± SD age, 13.84 ± 9.53 years; BMI Z-score, 0.33 ± 1.07; 56.1% male) and 3,720 PTP participants (age, 16.01 ± 12.33 years; BMI Z-score, 0.66 ± 1.3; 49.7% male). Log-rank testing and Cox regression analyses with adjustments (age, sex, race, BMI Z-score, HOMA-insulin resistance, and peak glucose/C-peptide levels, respectively) were performed. RESULTS In each of DPT-1 and PTP, higher 5-year diabetes progression risk was seen in those with time to peak glucose >30 min and time to peak C-peptide >60 min (P < 0.001 for all groups), before and after adjustments. In models examining strength of association with diabetes development, associations were greater for time to peak C-peptide versus peak C-peptide value (DPT-1: χ2 = 25.76 vs. χ2 = 8.62; PTP: χ2 = 149.19 vs. χ2 = 79.98; all P < 0.001). Changes in the percentage of individuals with delayed glucose and/or C-peptide peaks were noted over time. CONCLUSIONS In two independent at-risk populations, we show that those with delayed OGTT peak times for glucose or C-peptide are at higher risk of diabetes development within 5 years, independent of peak levels. Moreover, time to peak C-peptide appears more predictive than the peak level, suggesting its potential use as a specific biomarker for diabetes progression
