Implementation of control measures against an outbreak due to Clostridioides difficile producing toxin B in a tertiary hospital in Mexico

Objective. To describe the outbreak of Clostridioides difficile infection (CDI), and the impact of the prevention and control measures that were implemented in the “Hospital Juárez de México” (HJM) for its control. Study design. A cross-sectional, descriptive, observational, and retrospective study was designed. Methods. Information on the hospital outbreak and on health care-associated infections (HCAI) was obtained from the files of the Hospital Epidemiological Surveillance Unit (HESU) of the HJM. Results. A total of 15 cases of CDI were detected from February 20th to May 22nd, 2018, which represented 55.6% and 44.4% for the male and female gender, respectively, with an average age of 56 years and a range of 24 to 86 years old. It was possible to identify six failures and deficiencies that involved health personnel and hospital logistics through analyses based on the situational diagnosis in the services involved and through the construction of cause-effect diagrams. Additionally, through the detection of the outbreak by means of laboratory tests and timeline, the HESU team implemented measures and prospective surveillance to control and prevent the emergence of new cases. Conclusions. The implementation of basic quality tools, control measures, and the prospective epidemiological surveillance had a positive impact on the control against the outbreak of C. difficile producing toxin B

Tafí Viejo : between Alfonsin hope and reality rail (1984)

La llegada de la democracia en 1983 para los trabajadores ferroviarios de los talleres de Tafí Viejo fue sumamente significativa, debido a que en aquel momento el presidente Raúl Alfonsín impulsó la reapertura de dichos Talleres que fueron cerrados durante la última dictadura militar. El presente trabajo abordará las diversas tensiones y rivalidades que surgieron hacia el interior del movimiento obrero en torno a esta nueva oportunidad de recuperar sus puestos de trabajo, como también, identificaremos una serie de actores que participaron de este proceso movilizado por diversos intereses. Mediante la recopilación de testimonios orales, fuentes periodísticas y documentales del período intentaremos reconstruir este suceso tan importante para la historia reciente de Tafí Viejo y la provincia.The arrival of democracy in 1983 for the railway workers of the workshops in Tafi Viejo was extremely significant, because the president Raúl Alfonsín prompted the opening of these workshops that were closed during the last military dictatorship. The present paper reserch the tensions and rivalries that emerged in the interior of the labor movement around this new opportunity to recover their jobs, as well as identify a series of actors who participated in this process by different interests. Through the collection of oral testimony, journalistic sources and documentaries of the period we will try to reconstruct this event very important for the recent history of Tafí Viejo and Tucumán.Fil: Sosa Martos, Alberto Oscar.

Un largo camino a la privatización, memoria y resistencia en los trabajadores de los talleres de Tafí Viejo (Tucumán - Argentina)

En la última década del siglo XX, la instauración del neoliberalismo planteó una reestructuración del aparato productivo del país. El transporte ferroviario acusado de ser una actividad deficitaria, impulsó al presidente Carlos Menem a llevar a cabo un proceso de privatización y desmantelamiento de la estructura ferroviaria. En un camino de marchas y contramarchas, de lucha y resistencia del conjunto de la clase obrera ferroviaria, la aplicación de esta política se fue plasmando lentamente en el cierre de talleres y levantamiento de ramales. Veinte años después, el producto de dicha política fue el despido de más de 90.000 ferroviarios y el cierre de miles de kilómetros de vías. En este contexto los talleres ferroviarios de Tafí Viejo sentirán con fuerza el impacto de la política menemista, la precarización de las condiciones laborales, la falta de trabajo e insumos para la actividad concluirá con el segundo cierre del taller en 1996. El siguiente trabajo tiene como objetivo analizar la as concepciones de crisis ferroviaria que construyeron e internalizaron los trabajadores en sus memorias, y como se estructuro a partir de la experiencia previa los procesos de resistencia frente a las políticas de reducción y desmantelamiento productivo de los talleres planteado por las políticas neoliberales del menemismo.Fil: Sosa Martos, Alberto Oscar.

A mathematical model for transfer of O<SUB>2</SUB> and CO<SUB>2</SUB> in a membrane artificial lung

An analysis of oxygen absorption and carbon dioxide desorption in a film of blood through a gas-permeable membrane is presented. The mathematical analysis treats blood as a homogeneous, non-Newtonian fluid, in which the system pO2, pCO2 hemoglobin, pH is always in equilibrium due to the reaction rate in the erythrocites. Influence of flow rate, hematocrit and gas composition on blood saturation are studied, and the possibility of calculating an optimal membrane length is found.Facultad de Ingenierí

Turtles in the Dust: Effects of Hands-on Scientific Training on a Group of Behaviorally At-risk Students’ Knowledge and Empathy

We taught a group of behaviorally at-risk students lessons on box-turtle biology and natural history before translocating hatchling Ornate Box Turtles (Terrapene ornata ornata) to a nature area adjacent to their school. The students then assisted with data collection and ultimately used telemetry to re-locate the turtles and independently collect data. Each student in the experimental group was given a questionnaire prior to beginning and again after completion of the program, with questions covering box-turtle biology, natural history, and empathy toward animals. Students in a control group were given the same questionnaire at similar times. Students in the experimental group felt they improved their knowledge concerning box-turtle biology and natural history after training, whereas control group students did not. Neither group, however, showed a change in empathy between the pre- and post questionnaires. Incorporating behaviorally at-risk students in research projects may enable researchers to complete projects while at the same time involving an often-neglected portion of the population

Characterization of cultural soil profile on natural pastures : Santa Fe (Argentina)

En la región pampeana son comunes las áreas mal drenadas destinadas a ganadería en base a pastizales naturales. En ellas la vegetación natural es compleja y está influenciada por la interacción de aspectos climáticos, edáficos y por la historia del uso y del manejo. Las características edáficas afectadas por el manejo se expresan en el perfil cultural del suelo (PC); su caracterización es una herramienta importante para identificar limitantes a la productividad y aportar elementos para la toma de decisiones de manejo. Ante la ausencia de métodos que caractericen y cuantifiquen el estado del PC, se propone un índice (IPC) que, considerando el reconocimiento y la valoración de ciertas características edáficas indicadoras, asigna un valor numérico al estado del PC. En un pastizal natural, próximo a una cañada ubicada en el sur de la provincia de Santa Fe, se reconocieron tres áreas o unidades forrajeras (UF) con cierta homogeneidad en las características edáficas, forrajeras y paisajísticas. En las mismas se caracterizó el estado del PC y se calculó el IPC. El método desarrollado permitió identificar en cada UF limitantes edáficas derivadas del manejo y, a partir del índice generado, clasificar los respectivos PC según su estado.Low drained areas devoted to livestock breeding based on natural pastures are common in the Humid Pampas. In these areas natural vegetation is complex and is influenced by the interaction of climatic and edaphic aspects and by the management and use history. Edaphic characteristics affected by management are expressed in the cultural soil profile (CP), and their characterization is an important tool to identify productivity limitations and to convey elements for management decision-making. Based on the lack of methods to characterize and quantify the CP, we proposed and index that, considering the recognition and valuation of certain indicative edaphic characteristics, assigns a numeric value to the CP status. In a natural pasture, next to a lowland placed in the South of Santa Fe Province, three forage units (FU) with certain homogeneity in the edaphic, forage and landscape characteristics were recognized. In these units, the CP status and was characterized and the cultural profile index (CPI) was calculated. The method developed allowed to identify in each FU, the edaphic limitations derived from management and the proposed index allowed to classify the respective CP according to their status.Fil: Zerpa, Gabriel.Fil: Sosa, Oscar.Fil: Montico, Sergio.Fil: Martín, Beatriz
