Background: Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual) to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity) at three ecological levels (the family, school, and community).
Single-agent dactinomycin has activity in patients with low-risk GTD who develop MTX resistance and whose hCG is low. Simplifying the stratification of GTD into two classes (low- and high-risk) does not compromise overall outcome and may reduce the risk of second tumors.
Background: Although several previous projects have attempted to address the issue of child obesity through school-based interventions, the overall effectiveness of school-based programs on health-related outcomes in youth has been poor. Thus, it has been suggested that multi-level interventions that aim to influence healthy lifestyle behaviors at the community, school and family levels may prove more successful in the prevention of childhood obesity.
SATB2 is frequently expressed in appendiceal mucinous neoplasms. In the context of a mucinous neoplasm involving the ovary, any SATB2 positivity should raise the possibility of appendiceal origin. Expression of CK20, CDX2 and MUC2 supports appendiceal origin only when diffuse and strong. These and other markers, such as CK7 and PAX8, are recommended in the work-up of ovarian mucinous tumours with any clinical or pathological features suggestive of secondary origin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
