Abnormality of adipokines and endothelial dysfunction in Mexican obese adolescents with insulin resistance.

Purpose: The aim of this study was to investigate the possible relationship among insulin resistance (IR), endothelial dysfunction, and alteration of adipokines in Mexican obese adolescents and their association with metabolic syndrome (MetS).

Materials And Methods: Two hundred and twenty-seven adolescents were classified according to the body mass index (BMI) (control: N=104; obese: N=123) and homeostasis model of the assessment-insulin resistance index (HOMA-IR) (obese with IR: N=65). The circulating concentrations of leptin, adiponectin, soluble intercellular adhesion molecule-1 (sICAM-1), and IR were determined by standard methods.

Determinants of performance of health systems concerning maternal and child health: a global approach.

Aims: To assess the association of social determinants on the performance of health systems around the world.

Methods: A transnational ecological study was conducted with an observation level focused on the country. In order to research on the strength of the association between the annual maternal and child mortality in 154 countries and social determinants: corruption, democratization, income inequality and cultural fragmentation, we used a mixed linear regression model for repeated measures with random intercepts and a conglomerate-based geographical analysis, between 2000 and 2010.
