The mortality from sepsis complicated by renal failure remains extremely high despite the application of modern renal replacement therapy. This study investigated whether treatment with a bioartificial kidney consisting of a hemofilter in a continuous venovenous hemofiltration circuit (CVVH) with a cartridge containing renal proximal tubule cells, also called the Renal Tubule Assist Device (RAD), would alter the course of sepsis in an animal model. The RAD has been previously characterized in vitro and ex vivo and provides transport, metabolic and endocrine activity. Mongrel dogs (n = 10) underwent surgical nephrectomy and 48 h later were treated with CVVH and either a RAD containing cells (n = 5) or an identically prepared sham cartridge (n = 5). After 4 h of therapy, intravenous endotoxin 2 mg/kg was infused over 1 h to simulate gram-negative septic shock. Data on blood pressure, cardiac output and systemic markers of inflammation were collected. Mean peak levels of an anti- inflammatory cytokine, IL-10, were significantly higher in cell-treated animals (15.25 vs. 6.29 ng/ml; p = 0.037), and mean arterial pressures were higher in cell-treated versus sham-treated animals (p < 0.04). We have demonstrated that treatment of an animal model of endotoxin shock and renal failure with a bioartificial kidney has measurable effects on circulating mediators of inflammation and on hemodynamic stability of the challenged animal.
Screening instruments were well accepted and useful in detecting psychopathological conditions and functional impairment. Female service members might represent a high-risk group. These results are useful for those caring for service members during or after deployment.
Objetivo: Describir las características epidemiológicas y clínicas de los trabajadores de salud del Hospital Nacional Hipólito Unanue (HNHU) con diagnóstico de Tuberculosis (TBC) entre el 2006 y 2013. Material y métodos: Estudio observacional, descriptivo, longitudinal, retrospectivo, realizado en el HNHU de categoría III-1. La población estudiada estuvo constituida por los trabajadores de salud con diagnóstico de Tuberculosis entre el 2006 y el 2013. La muestra fue todo el universo. La técnica fue de documentación. Se utilizó estadística descriptiva y los programas Microsoft Excel 2010 y SPSS v 19. Resultados: Se identificaron 56 trabajadores de Salud con diagnóstico de TBC, 4 fueron BK (+++) y uno falleció. La frecuencia de los casos tuvo una tendencia a disminuir desde el 2008, con su valor más bajo en el 2012. Conclusiones: La mayoría fueron diagnosticados en el 2007 y 2013, médicos residentes, BK negativo, con TBC pulmonar sensible y del Servicio de Hospitalización de Especialidades.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
