Article Abstract
El lupus eritematoso generalizado (LEG) es una enfermedad autoinmune crónica caracterizada por la pérdida de la tolerancia a los antígenos propios y la síntesis de diferentes autoanticuerpos con la formación y depósito de complejos inmunes y el daño de múltiples órganos. Las células T reguladoras (Treg) desempeñan un papel esencial en el mantenimiento de la tolerancia periférica, controlan el estado de activación del sistema inmune y limitan las respuestas autoinmunes. El estudio del número y la función de las diferentes subpoblaciones de células Treg en LEG ha sido objeto de una intensa investigación. Dependiendo del fenotipo de las células Treg analizado se ha reportado que la frecuencia de estas células en pacientes con LEG se encuentra disminuida, aumentada o sin alteraciones. Además, diferentes grupos han descrito que la función supresora de las células Treg de los pacientes con LEG se encuentra reducida o no se ve afectada. En conjunto, lo datos reportados sugieren que las células Treg desempeñan un papel relevante en la patogénesis del LEG y que estos linfocitos pueden ser considerados blancos potenciales para el diseño de nuevas estrategias terapéuticas para esta enfermedad.

Background: Enterotoxigenic F4 E. coli (F4-ETEC) pose an economic threat to the swine industry through reduced growth, increased mortality and morbidity, and increased costs associated with treatment. Prevention and treatment of F4-ETEC often relies on antimicrobials; however, due to the threat of antimicrobial resistance, antimicrobial use is being minimized, and hence alternative control methods are needed.

Unlabelled: Data from low and middle-income countries (LMICs) on multidrug-resistant microorganisms (MDROs) in intensive care units (ICUs) are scarce. Working in several ICUs in Argentina, we sought to estimate the prevalence and characteristics of MDRO infections and carbapenemase-producing Enterobacterales (CPE) colonization. Mortality associated with MDRO infection was also evaluated.

Background/aims: Levator ani syndrome (LAS) is a pathology that is both difficult to diagnose and treat. The effectiveness of current treatments, which are mostly administered with special devices in advanced healthcare centers, is controversial. The aim of the study is to investigate the effects of glyceryl trinitrate, which is easily accessible and can be applied by the patient, in the treatment of LAS.
