Precursors to aggression are evident by 6 months of age.
We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were significantly associated with known risk factors for high leve...
متن کاملAge-dependent differences in microglial responses to systemic inflammation are evident as early as middle age.
Whereas age increases microglial inflammatory activities and impairs their ability to effectively regulate their immune response, it is unclear at what age these exaggerated responses begin. We tested the hypotheses that augmented microglial responses to inflammatory challenge are present as early as middle age and that repeated stimulation of primed microglia in vivo would reveal microglial se...

متن کاملIron Status at Age 6 Months in Colombian Infants Exclusively Breast-fed for 4 to 5 Versus 6 Months.
OBJECTIVES The optimal age for introducing complementary feeding to breast-fed infants may differ depending on the setting. Prolonged exclusive breast-feeding (EBF) protects against infection but may increase the risk of iron deficiency (ID)/anaemia (IDA) in vulnerable infants. The aim of the present study was to compare haemoglobin (Hb), serum ferritin (SF), anaemia (Hb < 11 g/L), ID (SF < 12 ...
متن کاملPrognosis of convulsions between 1 and 6 months of age.

Between 1 and 4 years after presentation the condition of 19 patients was normal, 3 were mildly handicapped, 4 severely handicapped, and 2 had died. Normal physical examination and electroencephalogram at time of prese...
