“…The drop in BSID-II scores from 9 months to 30 months was not expected for normal infants and toddlers (Harris, et al, 2005;Niccols and Latchman, 2002) and may be important. This finding does not appear to be related to administration of the test as scoring reliabilities were uniformly high and the variability around the BSID-II means was similar to what would have been expected if US children had been examined.…”

Neurodevelopmental effects of maternal nutritional status and exposure to methylmercury from eating fish during pregnancy

et al. 2008

Fish contain nutrients that promote optimal brain growth and development but also contain methylmercury (MeHg) that can have toxic effects. The present study tested the hypothesis that the intake of selected nutrients in fish or measures of maternal nutritional status may represent important confounders when estimating the effects of prenatal methylmercury exposure on child development. The study took place in the Republic of Seychelles, an Indian Ocean archipelago where fish consumption is high. A longitudinal cohort study design was used. A total of 300 mothers were enrolled early in pregnancy. Nutrients considered to be important for brain development were measured during pregnancy along with prenatal MeHg exposure. The children were evaluated periodically to age 30 months. There were 229 children with complete outcome and covariate data for analysis. The primary endpoint was the Bayley Scales of Infant Development-II (BSID-II), administered at 9 and 30 months of age. Combinations of four secondary measures of infant cognition and memory were also given at 5, 9 and 25 months. Cohort mothers consumed an average of 537 gm of fish (9 meals containing fish) per week. The average prenatal MeHg exposure was 5.9 ppm in maternal hair. The primary analysis examined the associations between MeHg, maternal nutritional measures and children's scores on the BSID-II and showed an adverse association between MeHg and the mean Psychomotor Developmental Index (PDI) score at 30 months. Secondary analyses of the association between the PDI and only MeHg alone or nutritional factors alone showed only a borderline significant association between MeHg and the PDI at 30 months and no associations with nutritional factors. One experimental measure at 5 months of age was positively associated with iodine status, but not prenatal MeHg exposure. These findings suggest a possible confounding role of maternal nutrition in studies examining associations between prenatal MeHg exposures and developmental outcomes in children.

Background and Purpose— Cerebral sinovenous thrombosis is a rare disease with severe neurological sequelae. The aim of this retrospective multicenter study was to investigate the clinical course, possible risk factors, and outcome of a cohort of neonatal patients with sinovenous thrombosis and, second, to estimate the incidence in The Netherlands. Methods— From January 1999 to March 2009, a review of all neonatal patients with sinovenous thrombosis from 6 tertiary neonatal intensive care units was performed. Population characteristics, clinical presentation, (prothrombotic) risk factors, neuroimaging, interventions, and neurodevelopment were evaluated. An estimated incidence was calculated based on the Netherlands Perinatal Registry. Results— Fifty-two neonates were included (39 boys) with a median gestational age of 39 weeks (range, 30 to 42 weeks; 5 preterm). An assisted or complicated delivery occurred in 32 of 52. Presenting symptoms developed at a median postnatal age of 1.5 days (range, 0 to 28 days) and consisted mainly of seizures (29 of 52). All sinovenous thrombosis cases were confirmed with MRI/MR venography. Multisinus thrombosis was most common followed by superior sagittal sinus thrombosis. FII G20210A mutation was present in 2 of 18 tested neonates (11%). Anticoagulation therapy (in 22 of 52) did not result in hemorrhagic complications. At follow-up (median age, 19 months; range, 3 to 72 months), moderate to severe neurological sequelae were present in 38%. The mortality was 10 of 52 (19%). A variable, although high yearly incidence of 1.4 to 12 per 100 000 term newborns was found. Conclusions— Neonatal sinovenous thrombosis is a multifactorial disease. The estimated incidence in The Netherlands seems higher than reported elsewhere.

“…Few international studies were conducted to investigate the stability of this population concerning mental performance 11,14,22 . Bayley Scales assess each stage development level and their main feature is to enable the diagnosis of developmental delay and enable the planning of intervention strategies 15 .The measure of stability in repeated assessments is important to assess the progress of these children .…”

O objetivo do estudo foi investigar a estabilidade do desempenho mental de bebês prematuros de muito baixo peso ao nascer ao longo dos dois primeiros anos de vida e identificar os fatores associados ao seu desempenho mental. Estudo de coorte com 109 crianças. A Escala Mental da Bayley Scales of Infant Development - Second Edition foi aplicada aos 6, aos 12 e entre 18-24 meses de idade corrigida. A estabilidade dos escores entre as avaliações foi investigada através de análise de variância para medidas repetidas. A associação entre as características neonatais e sociais no desenvolvimento mental foi verificada por análise multivariada através de regressão linear, considerando como desfechos os Índices de Desenvolvimento Mental aos 6 meses, 12 meses e entre 18-24 meses de idade corrigida. A média do Índice de Desenvolvimento Mental aos 6 meses foi 83,4 (DP: 12,4), aos 12 meses foi 86,4 (DP: 13,9) e aos 18-24 meses foi 73,4 (DP: 14,5). Observou-se uma diminuição significativa de 13 pontos no escore aos 18-24 meses de idade corrigida. O Índice de Desenvolvimento Mental não apresentou estabilidade ao longo dos dois primeiros anos de vida nesta população de prematuros, exceto para as crianças que tiveram pneumonia neonatal, cujo desempenho foi insatisfatório em todas as avaliações. Dos fatores de risco investigados, apenas o sexo masculino e a pneumonia neonatal estiveram associados aos desfechos.
