RESUMENLa reestenosis es la principal limitación del intervencionismo coronario percutáneo con stent a mediano y largo plazo con frecuentes recurrencias después de un primer episodio. Con el objetivo de identificar facto-res asociados a la recurrencia de la misma, se realizó un estudio de cohorte retrospectiva en el hospital “Hermanos Ameijeiras” donde se incluyeron 166 pacientes con reestenosis luego del implante de stent coronarios convencionales entre enero del 2010 y diciembre del 2013. Para determinar las variables asociadas con el comportamiento reestenótico recidivante se practicó un análisis univariado y multivariado (regresión logística). El 69,3% fueron hombres, 101(60.8%) presentaron angina estable, 44% tuvieron reestenosis difusa y la arteria descendente anterior estuvo afectada en 92 pacientes. Fueron tratados mediante angioplastia coronaria 130 pacientes, en el 54.2% se implantaron stents convencionales y la tasa de éxitoangiográfico fue del 97,7%. La reestenosis recidiva en un 25,3% de los casos. El patrón morfológico difuso constituyó la única variable que se asoció de forma independiente (p=0.037) a la recurrencia de la reesteno-sisintrastent.Palabras clave: stent metálicos no recubiertos, reestenosis._________________________________________________________________________________AbstractStent restenosis is the main medium and long term limitation of percutaneous coronary intervention with stent.

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
