En enero de 2006, en Venezuela, se reguló la dispensación de algunos antibióticos, condicionando su venta a la presentación de la receta médica. En este trabajo se determinó el impacto de esta medida sobre la resistencia bacteriana. El consumo de antibióticos se expresó como el número de Dosis Diarias Definidas/1.000 habitantes/día, calculado con la información suministrada por el International Marketing System Health. La información de resistencia bacteriana se obtuvo del Programa Venezolano de Vigilancia de la Resistencia Bacteriana a los Antimicrobianos. Se realizó análisis de correlación entre las variables. Los resultados demuestran que tanto el consumo como la resistencia bacteriana se incrementaron significativamente durante el período posterior a la regulación. Es necesario ampliar la aplicación de esta medida a todos los antibióticos, así como implementar mejoras en la educaci...

Glomerular filtration rate (GFR) is the best measure of overall kidney function in health and disease. There is no consensus about the method to be used routinely to measure and/or estimate GFR. The objectives of this study were to assess which method correlates better with creatinine (Cr) clearance, extensively used in medical practice, as well as assessing the efficacy of the modification of diet in renal disease (MDRD) equation, in our population. We studied 262 adult out-patients with stable CKD on conservative treatment. GFR was evaluated by Cr clearance, Cockcroft-Gault (CG) formula, the mean of urea and Cr clearances (total clearance (TCl)), the MDRD study equation, with and without the variable for African-Americans (MDRD1) and the simplified one (MDRDs). Data were analyzed by Pearson's correlation coefficient (r) and Bland & Altman plot analysis. Pearson's correlation showed that all methods where similar when compared to Cr clearance. A high correlation was observed between CG and MDRD equations, and TCl and MDRD equations showed the worst correlation. Among the MDRD equations, no differences were found. Bland-Altman plot analysis indicated a concordance among the studied methods. The CG formula could replace Cr clearance in our population, being simpler than and equally as sensitive as the MDRD equation.

Surveyed firms were asked to indicate their level of utilization of several competitive methods. The results of factor analysis of the survey data indicate that 30 of the 33 competitive methods covered in this study represent seven underlying strategy dimensions. Further analysis revealed that there is some congruence between the derived strategy dimensions and established strategy typologies in the literature. Cluster analysis revealed that each of the responding firms could be classified into one of four hybrid or mixed strategy orientations. However, differences in strategy orientation were not statistically significant in explaining differences in the financial performance of these organizations. These findings are discussed in the light of their implications for strategy development, strategy choices and performance evaluation in the Portuguese service sector.

The purpose of this study is to examine data gathered from a sample of one-hundred business students from Al Akhawayn University in Morocco, who recently completed their internships, to determine the profile of desired skills and abilities employers are looking for. Based on the results of this study, it appears that Moroccan businesses tend to value students with the right toward the organizations and its culture. Furthermore, these organizations are looking for their entry-level managers to be problem-solvers.
