Contextual Social Inequities and Occurrence of Dental Caries in Adolescents: A Systematic Review.

Purpose: This systematic review sought to determine whether there is consistent evidence of the association between contextual social inequities and the occurrence of dental caries in adolescents.

Materials And Methods: An electronic survey in ISI Web of Science, SCOPUS, MEDLINE, LILACS, Cochrane Library, and SciELO databases was performed, establishing a specific search strategy in each of them. Only analytical articles in which social indicators were measured at the contextual level published up to December 2015 were included.

High muscle sympathetic nerve activity is associated with left ventricular dysfunction in treated hypertensive patients.

Background: The presence of asymptomatic left ventricular diastolic dysfunction (LVDD) in hypertensive patients can be associated with the development of cardiac events. The increase in sympathetic activity may be 1 of the mechanisms that predisposes to this outcome. In this study, we analyzed 2 hypotheses: (i) whether sympathetic activity is higher in the presence of LVDD, independent of blood pressure control and (ii) whether different classes of LVDD have a different effect on sympathetic activity.
