Determinación de VSG: comparación de los métodos de Wintrobe y microhematocrito

Objetivo Establecer la correlación entre los métodos de Wintrobe y de micro-hematocritoMétodos Se tomaron 407 pacientes asistentes a un laboratorio de tercer nivel a quienes en forma simultánea se les realizó las dos pruebas en estudio.Resultados Mediante el un método estadístico de regresión lineal se encontró un coeficiente de correlación de 0,99.Conclusión Ambos métodos pueden contribuir al análisis clínico de los pacientes a quienes se les solicitó la prueba con fines de diagnóstico, control y seguimiento de diferentes patologías

Active Surveillance of Antimicrobial Resistance and Carbapenemase-Encoding Genes According to Sites of Care and Age Groups in Mexico: Results from the INVIFAR Network

We analyzed the antimicrobial resistance (AMR) data of 6519 clinical isolates of Escherichia coli (n = 3985), Klebsiella pneumoniae (n = 775), Acinetobacter baumannii (n = 163), Pseudomonas aeruginosa (n = 781), Enterococcus faecium (n = 124), and Staphylococcus aureus (n = 691) from 43 centers in Mexico. AMR assays were performed using commercial microdilution systems (37/43) and the disk diffusion susceptibility method (6/43). The presence of carbapenemase-encoding genes was assessed using PCR. Data from centers regarding site of care, patient age, and clinical specimen were collected. According to the site of care, the highest AMR was observed in E. coli, K. pneumoniae, and P. aeruginosa isolates from ICU patients. In contrast, in A. baumannii, higher AMR was observed in isolates from hospitalized non-ICU patients. According to age group, the highest AMR was observed in the ≥60 years age group for E. coli, E. faecium, and S. aureus, and in the 19–59 years age group for A. baumannii and P. aeruginosa. According to clinical specimen type, a higher AMR was observed in E. coli, K. pneumoniae, and P. aeruginosa isolates from blood specimens. The most frequently detected carbapenemase-encoding gene in E. coli was blaNDM (84%)
