Journal ArticleDOI
Viral and bacterial co-infection in severe pneumonia triggers innate immune responses and specifically enhances IP-10: a translational study.
Jonathan Hoffmann,Daniela Machado,Olivier Terrier,Stephane Pouzol,Melina Messaoudi,Wilma Basualdo,Emilio E. Espínola,Rosa Guillén,Manuel Rosa-Calatrava,Valentina Picot,Thomas Bénet,H. P. Endtz,Graciela Russomando,Glaucia Paranhos-Baccala +13 more
TL;DR: It is demonstrated that viral and bacterial co-infection modulates the JAK-STAT signaling pathway and leads to exacerbated IP-10 expression, which could play a major role in the pathogenesis of pneumonia.
Journal ArticleDOI
Clinically significant coagulase-negative staphylococci: Most frequent species and virulence factors
Norma Fariña,Letizia Carpinelli,Margarita Samudio,Rosa Guillén,Florentina Laspina,Ramona Sanabria,Sonia Abente,Ladis Rodas,Pedro González,Herminia Miño de Kaspar +9 more
TL;DR: The frequency of S. lugdunensis, the most virulent coagulase-negative staphylococci species, was relatively high and the main virulence factor in S. epidermidis was biofilm production, being higher in those resistant to methicillin.
Journal ArticleDOI
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) clones from Paraguayan children.
Fátima Rodríguez,Claudia Salinas,Silvina Fernández,Sol Haim,Marta Mollerach,Wilma Basualdo,Héctor Escobar Castro,Beatriz Quiñónez,Rocio Arguello,Mónica Rodríguez,Lorena Grau,Carmen Espínola,Gladys Velázquez,Gloria Samudio,Gloria Gómez,Ana Campuzano,Juana Ortellado,Patricia Almada,Rosa Guillén +18 more
TL;DR: This is the first study that provides epidemiological information as well as microbiological and molecular characteristics of CA-MRSA isolates recovered from children from Asunción and the Central Department of Paraguay.
Journal ArticleDOI
Serotypes of Streptococcus pneumoniae in Children Aged <5 Years Hospitalized With or Without Pneumonia in Developing and Emerging Countries: A Descriptive, Multicenter Study
C. Dananché,Glaucia Paranhos-Baccala,Melina Messaoudi,Mariam Sylla,Shally Awasthi,Ashish Bavdekar,Sonali Sanghavi,Souleymane Diallo,Jean-William Pape,Vanessa Rouzier,Monidarin Chou,Tekchheng Eap,Mala Rakoto-Andrianarivelo,Muriel Maeder,Jianwei Wang,Lili Ren,Budragchaagiin Dash-Yandag,Pagbajabyn Nymadawa,Rosa Guillén,Graciela Russomando,H. P. Endtz,Florence Komurian-Pradel,Philippe Vanhems,Valentina Picot +23 more
TL;DR: Most serotypes independently associated with nasopharyngeal carriage or pneumonia are covered by PCV13, suggesting that increased PCV coverage would reduce the burden of S. pneumoniae-related pneumonia.
Evaluación de parámetros litogénicos en pacientes con urolitiasis que concurrieron al Instituto de Investigaciones en Ciencias de la Salud en el año 2009
TL;DR: In this article, a study of 40 patients with diagnostico de urolitiasis was conducted, and the authors determined the valores of analitos with potencial litogenico or inhibidor de cristalizacion, in muestras de sangre and orina.
