Besides health-related triggers, psychological stress might be related to relapse. This longitudinal study examined the link between perceived stress, emotional valence (feeling happy vs.

Brain development of very preterm and very low-birthweight children in childhood and adolescence: a meta-analysis.

Aim: The aim of this article was to clarify the impact and consequences of very preterm birth (born <32wks of gestation) and/or very low birthweight ([VLBW], weighing <1500g) on brain volume development throughout childhood and adolescence.

Method: The computerized databases PubMed, Web of Knowledge, and EMBASE were searched for studies that reported volumetric outcomes during childhood or adolescence using magnetic resonance imaging and included a term-born comparison group. Fifteen studies were identified, encompassing 818 very preterm/VLBW children and 450 term-born peers.
