Preterm children's long-term academic performance after adaptive computerized training: an efficacy and process analysis of a randomized controlled trial.

Background: Adaptive computerized interventions may help improve preterm children's academic success, but randomized trials are rare. We tested whether a math training (XtraMath®) versus an active control condition (Cogmed®; working memory) improved school performance. Training feasibility was also evaluated.

Coagulation parameters in hyperthyroid cats before and after radioiodine treatment compared with healthy controls.

Objectives: The aim of the study was to describe the coagulatory state of hyperthyroid cats before and after successful radioiodine therapy (RIT) compared with healthy age-matched controls, using classical coagulation parameters and thromboelastogram (TEG) as a global assessment method. The differences in coagulation activity after RIT, depending on the thyroid hormone (normal vs low total thyroxine [T4]) state, were also evaluated.

Methods: Fifteen hyperthyroid cats and 10 healthy age-matched controls were recruited.

Origins and Predictors of Friendships in 6- to 8-Year-Old Children Born at Neonatal Risk.

Objective: To test effects of gestational age (GA), early social experiences, and child characteristics on children's friendships and perceived peer acceptance.

Study Design: As part of the prospective Bavarian Longitudinal Study (1147 children, 25-41 weeks GA), children's friendships (eg, number of friends, frequency of meeting friends) and perceived peer acceptance were assessed before school entry (6 years of age) and in second grade (8 years of age) using child and parent reports. The parent-infant relationship was evaluated during the 5 months after birth.
