OBJECTIVE: The study aimed to assess bronchopulmonary dysplasia (BPD) as a predisposing factor for alteration in the psychomotor development index (PDI) in premature infants and verify the incidence of neuromotor alterations at 6 months corrected age. METHOD: This was a prospective cohort study that followed the neuromotor development of 152 very low birth weight premature infants, with psychomotor development index as the outcome. The study used the Bayley Scale of Infant Development at 6 months corrected age, and neurological examination. RESULTS: Incidence of BPD was 13.2% (n=20). Logistic regression analysis showed an association between BPD and altered psychomotor development index (OR 3.98; 95%CI: 1.04-15.1) after adjusting for confounding variables. Neurological examination was altered in 67.1% of the 152 infants. CONCLUSION: Bronchopulmonary dysplasia acted as an independent predisposing factor for alteration in the psychomotor development index in premature infants at 6 months corrected age.

A modified administration of the Kent Infant Development Scale for infants 6 to 8 mo. old was used in a prospective study of risk factors in infant development. The Mental Development Index and Psychomotor Development Index of the Bayley Scales of Infant Development were also administered at 6 mo., the Mental Index only at 1 and 2 yr. and the Stanford-Binet Intelligence Scale at age 3. The modified administration is described. Concurrent validity with the 6-mo. Bayley scales was substantial. Adequate predictive validity for 1- and 2-yr. Bayley scores and 3-yr. Stanford-Binet IQ was achieved with the Kent as compared to the predictive ability of the 6-mo. Bayley index.

Objective: This study aimed to investigate the application of MEIR (Massage, Exercises, Intelligence training, and Rehabilitation training) in Chinese VLBW infants and to observe its effects on infants’ growth and development. Methods: Clinical data of 92 VLBW infants who were treated at the neonatal intensive care unit (NICU) of Loudi Central Hospital were retrospectively analyzed. The patients were grouped as the MEIR group (n=47) and controls (n=45). Physical and neurodevelopment development were compared between the two groups. Results: There were differences in height and weight and head circumference between the two groups at all corrected ages (all P<0.05). Abnormal motions, reflexes, muscular tension, audio-visual reactions, and posture, and the total numbers of abnormalities of 3-, 6-, 9- and 12-corrected month-old infants in the MEIR group were lower than in the control group (all P<0.05). The mental development index and psychomotor development index of 6- and 12- corrected month infants in the MEIR group were higher than in the control group (all P<0.05). Conclusion: MEIR could improve the physical and neurological developments of VLBW infants, reduce the incidence of adverse events, and improve their growth and development.

Bayley Scales

Abstract OBJECTIVES Neurodevelopmental disability is the most common complication among congenital heart surgery survivors. The Bayley scales are standardized instruments to assess neurodevelopment. The most recent edition (Bayley Scales of Infant and Toddler Development 3rd Edition, Bayley-III) yields better-than-expected scores in typically developing and high-risk infants than the second edition (Bayley Scales of Infant Development 2nd Edition, BSID-II). We compared BSID-II and Bayley-III scores in infants undergoing cardiac surgery. METHODS We evaluated 2198 infants who underwent operations with cardiopulmonary bypass between 1996 and 2009 at 26 institutions. We used propensity score matching to limit confounding by indication in a subset of patients (n = 705). RESULTS Overall, unadjusted Bayley-III motor scores were higher than BSID-II Psychomotor Development Index scores (90.7 ± 17.2 vs 77.6 ± 18.8, P &lt; 0.001), and unadjusted Bayley-III composite cognitive and language scores were higher than BSID-II Mental Development Index scores (92.0 ± 15.4 vs 88.2 ± 16.7, P &lt; 0.001). In the propensity-matched analysis, Bayley-III motor scores were higher than BSID-II Psychomotor Development Index scores [absolute difference 14.1, 95% confidence interval (CI) 11.7–17.6; P &lt; 0.001] and the Bayley-III classified fewer children as having severe [odds ratio (OR) 0.24; 95% CI 0.14–0.42] or mild-to-moderate impairment (OR 0.21; 95% CI 0.14–0.32). The composite of Bayley-III cognitive and language scores was higher than BSID-II Mental Development Index scores (absolute difference 4.0, 95% CI 1.4–6.7; P = 0.003), but there was no difference between Bayley editions in the proportion of children classified as having severe cognitive and language impairment. CONCLUSIONS The Bayley-III yielded higher scores than the BSID-II and classified fewer children as severely impaired. The systematic bias towards higher scores with the Bayley-III precludes valid comparisons between early and contemporary cardiac surgery cohorts.

In this prospective, longitudinal study, the relative impact of intracranial hemorrhage and prolonged mechanical ventilation on developmental progress during the first 18 months of life of infants weighing 1,200 g or less at birth was examined. A total of 159 surviving infants were divided into two groups: infants with and those without intracranial hemorrhage. These groups were then subdivided into groups of infants receiving prolonged mechanical ventilation (&gt; 21 days) and those mechanically ventilated for 21 days or less, thus creating four subgroups. Group 1 (intracranial hemorrhage and prolonged mechanical ventilation) and group 3 (intracranial hemorrhage and no prolonged mechanical ventilation) showed no statistically significant differences for severity of intracranial hemorrhage, persistence of yentriculomegaly, or presence of periventricular leukomalacia. A repeated-measures analysis of variance demonstrated a main effect for prolonged mechanical ventilation on outcome as measured by the Bayley Mental Development Index and Bayley Psychomotor Development Index at 4, 8, 12, and 18 months of age (corrected for prematurity). Forward stepwise regression revealed prolonged mechanical ventilation to be the best predictor of Bayley indexes at all ages except 4 months of age, for which the Psychomotor Development Index was best predicted by length of hospitalization. No main effect for intracranial hemorrhage was demonstrated, but the motor performance of infants with intracranial hemorrhage declined significantly with age. By contrast prolonged mechanical ventilation was associated with uniformly poor performance at every age and serves as a powerful marker for poor developmental progress during the first 18 months of life in infants weighing 1,200 g or less at birth.
