Role of repeated biopsy of the prostate in predicting disease progression in patients with prostate cancer on active surveillance

Active surveillance (AS) with deferred treatment is an established management option for patients with prostate cancer and favorable clinical parameters. The impact of repeat biopsy after diagnosis was examined in a cohort of men with prostate cancer on AS.

The Development of Prosocial Behaviors in Young Children: A Prospective Population-Based Cohort Study

ABSTRACT Researchers know relatively little about the normative development of childrens behaviors aimed at alleviating distress or discomfort in others. In this article, the authors aim to describe the continuity and discontinuity in the degree to which young children in the general population are reported to exhibit specific prosocial behaviors. Data came from the Québec Longitudinal Study of Child Development. Consistent with Hays model of prosocial development, the results show that there were about as many children who stopped exhibiting prosocial behaviors between 29 and 41 months of age as there were children who started doing so during this period. Further, gender differences (girls > boys) in prosocial behaviors are either emerging or at least increasing in magnitude, with girls being more likely to start and boys being more likely to stop exhibiting these behaviors between 29 and 41 months of age. Consistent with the early-onset hypothesis, children who exhibit prosocial behaviors at 17 months of age are less likely to stop exhibiting the same behaviors between 29 and 41 months of age. Otherwise, if they did not exhibit prosocial behaviors at 29 months of age, they are also more likely to start doing so in the following year.

Obstetrical complications and physical aggression behaviours before the age of 2

Obstetrical Complications and Physical Aggression Behaviours Before the Age of 2 Objective: To determine if infants who experienced obstetrical complications (OCs) have a greater tendency to show frequent physical aggression behaviours before the age of 2, independent of gender and family income. Another objective was to explain, at least partly, the sexual differences found in some behaviours using OCs. Method: Data were from the Québec Longitudinal Study of Child Development (QLSCD). OCs were measured with Agpar scores (< 7) at 1 minute following birth. Family income level— sufficient or not—was measured when infants were about 5 months old. Twelve behaviours of physical aggression, opposition defiance, and hyperactivity were measured when infants were about 17 months old. Weighted data were analyzed using hierarchical log-linear models. Results: Results suggest that infants with an Agpar score of less than 7 after birth are generally more likely to frequently display aggressive behaviours at 17 months, independent of gender and family income. Further, these results suggest it may be possible to explain, by OCs, the greater tendency in boys to frequently display aggressive behaviours at 17 months. Conclusions: Contrary to some hypotheses, it turns out that OCs have an impact on aggressive behaviours before the age of 2 independent of socioeconomic status.OBJECTIVE To determine if infants who experienced obstetrical complications (OCs) have a greater tendency to show frequent physical aggression behaviours before the age of 2, independent of gender and family income.
