OBJECTIVE to evaluate neonatal sepsis as a risk factor for abnormal neuromotor and cognitive development in very low birth weight preterm infants at 12 months of corrected age. METHODS this was a prospective cohort study that followed the neuromotor and cognitive development of 194 very low birth weight preterm infants discharged from a public neonatal intensive care unit. The Bayley Scale of...

Two new approaches foi the multivariate analysis of fish growth in aquaculture are presented. The first of these two approaches, the "extended Bayley plot" is a multiple regression expansion of an existing bivariate method, which permits the inclusion of environmental and treatment variables when estimating the parameters Lm and K of the von Bertalanflj. growth function, given precise measureme...

The failure of developmental tests in infancy to predict later competence may be because the tests ignore important dimensions of infant functioning. Yarrow and Pedersen (1976) have suggested that one such dimension could be mastery behavior, which involves persistence and investigation. Fiftythree infants were observed at 6 and 12 months during two 24-min play sessions. The Bayley Scales of In...

Objective: To describe the activities of a multiprofessional outpatient clinic performed by neonatologist, physiatrist, physical therapist, occupational therapist, speech therapist, audiologist and psychologist, who evaluated the development of premature newborns. Methods: Twenty children born at a tertiary-care hospital (São Paulo, Brazil), between April 2006 and April 2007, with birth weight ...

INTRODUCTION Uncertainty exists regarding the effects of iron supplementation during infancy on neurodevelopmental outcomes in the absence of anaemia. The aim of the study is to establish whether psychomotor and mental development is influenced by early iron supplementation in healthy, non-anaemic, exclusively or predominantly breastfed infants. METHODS AND ANALYSIS Healthy term infants will ...

BACKGROUND Advanced paternal age (APA) is associated with an increased risk of neurodevelopmental disorders such as autism and schizophrenia, as well as with dyslexia and reduced intelligence. The aim of this study was to examine the relationship between paternal age and performance on neurocognitive measures during infancy and childhood. METHODS AND FINDINGS A sample of singleton children (n...

OBJECTIVE We investigated the relationship between prenatal exposure to dichlorodiphenyltrichloroethane (DDT) and dichlorodiphenyldichloroethylene (DDE) and neurodevelopment of Mexican farm-workers' children in California. METHODS Participants from the Center for the Health Assessment of Mothers and Children of Salinas study, a birth cohort study, included 360 singletons with maternal serum m...

This study aims at testing the hypothesis that neurodevelopmental abilities at age 2 years are related with local brain microstructure of preterm infants at term equivalent age. Forty-one preterm infants underwent brain MRI with diffusion tensor imaging sequences to measure mean diffusivity (MD), fractional anisotropy (FA), longitudinal and transverse diffusivity (λ// and λ[perpendicular]) at t...

BACKGROUND AND OBJECTIVE Infant formula is supplemented with long-chain polyunsaturated fatty acids (LCPUFAs) because they are hypothesized to improve cognition. Several randomized controlled clinical trials have examined the effect of LCPUFA supplementation of infant formula on cognitive development. We conducted this meta-analysis to examine the efficacy of LCPUFA supplementation of infant fo...

OBJECTIVE Recent pesticide-monitoring results suggest that a shift in residential pesticide exposure from organophosphorus insecticides to pyrethroid insecticides has occurred. Pyrethroid insecticides are potential neurodevelopmental toxicants and have not been evaluated for developmental toxicity. Our objective was to explore the association between prenatal exposure to permethrin (a common py...
