The aim of this study was to measure cerebral cortical thickness, area and volume with an automated MRI technique in 15-year-old adolescents who had low birth(More)

OBJECTIVE To study perinatal risk factors for psychiatric symptoms in adolescents born preterm with very low birth weight or at term, but small for gestational age (GA). METHOD Mental health was assessed in 65 adolescents born with very low birth weight (VLBW) (birth weight < or = 1500 g), 59 born term small for GA (birth weight <10th centile) and 81(More)
Serum phospholipid eicosapentaenoic (PL-EPA) and docosahexaenoic acid (PL-DHA) concentrations are associated with the dietary intake of omega 3 fatty acids. PL-EPA and PL-DHA concentrations measured 4 y apart in 211 diabetic patients were highly correlated, with Spearman correlation coefficients of 0.49 (p = 0.0001) and 0.64 (p = 0.0001), respectively.(More)
OBJECTIVE To evaluate the effect of a computerized working memory training program on both trained and non-trained verbal aspects of working memory and executive and memory functions in extremely low birth weight (ELBW; <1000 g) infants. STUDY DESIGN Sixteen ELBW infants and 19 term-born control subjects aged 14 to 15 years participated in the training(More)
BACKGROUND Being born with low birth weight may have an impact on different aspects of mental health, psychosocial functioning and well-being; however results from studies in young adulthood have so far yielded mixed findings. The aim of this study was to assess the long-term impact in young adulthood on self-reported mental health, health-related quality(More)

METHODS A total of 929 women and their children participating in a(More)

Group I (n = 10) was studied before the first feeding at 1 h and preprandially at 6 and 24 h. Group II (n = 10) was studied before the first feeding at 2 h of age and preprandially and(More)
