General public exposure to radiofrequency electromagnetic fields generated by mobile communications jammers

In recent years the communication services have seen a rapid progress and development, creating new scenarios of exposure to non-ionizing radiation (NIR). Due the preoccupation concerning the potential effects of the NIR arise. This paper approaches the study of a new emerging scenario given by exposure to NIR generated by mobile communications jammers in order to know the possible exposure levels, compared with the current limits and the levels in other studied scenarios. Such devices are installed in banks, offices and financial entities for safety reasons.Fil: Bruni, Rodrigo Gabriel. Universidad Nacional de Córdoba.

Experiencia en la UNC: Una aproximación a la internacionalización del currículum

La internacionalización del currículum (IC) implica la inclusión de dimensiones internacionales e interculturales en el contenido del currículo, así como en los procesos de enseñanza y aprendizaje y servicios de apoyo de un programa de estudios [Leask, 2012]. La finalidad es incorporar habilidades y competencias que permitan a los futuros profesionales desempeñarse en un ambiente internacional e intercultural.La Secretaría de Políticas Universitarias dependiente del Ministerio de Educación Argentino, como parte del Ciclo de Seminarios Web “La Internacionalización del Currículum en la Universidad Argentina”, organizó talleres de capacitación en esta temática, en los que la Universidad Nacional de Córdoba (UNC) participó activamente constituyendo dos equipos de trabajo con representantes de distintas unidades académicas. En uno de ellos, formó parte activa la Facultad de Ciencias Exactas, Físicas y Naturales (FCEFyN) y en este escrito se comparte la experiencia, y se exponen los resultados del trabajo realizado específicamente en la carrera de Ingeniería Electrónica. Esta primera experiencia consistió en el análisis desde la perspectiva de la IC que permite reconocer elementos de la currícula actual que colaboran con esta dimensión, como así también determinar aquellos puntos a fortalecer y las acciones necesarias para lograrlo.Fil: Guzmán, Claudia Alejandra.

Evaluación de la distribución de temperaturas en un perfil somero de suelo loéssico

En este trabajo se determina la distribución de temperaturas en profundidad somera en los suelos limosos del centro de Argentina a lo largo de ciertos períodos del año (invierno y verano), en las profundidades que se construyen habitualmente las cimentaciones superficiales (plateas y zapatas) de viviendas y donde se instalan sistemas geotérmicos de aire o agua de tipo horizontales. Se obtienen valores útiles para evaluar la potencial aplicación y eficiencia de sistemas someros para el aprovechamiento geotérmico de baja entalpía en viviendas en el centro de Argentina. El estudio del perfil de temperatura y humedad del subsuelo permite diseñar y modelar sistemas capaces de aprovechar la energía calorífica y disminuir el impacto ambiental producido por fuentes convencionales.In this work, it is obtained the distribution of temperatures in shallow depths in the silty soils of the central part of Argentina during certain periods of the year (winter and summer), in the depths where the superficial foundations (plates and footings) of houses are usually built and where horizontal geothermal systems are installed. Useful values are obtained to evaluate the potential application and efficiency of shallow systems for low-enthalpy geothermal use in houses in central Argentina. The study of the temperature and moisture profile of the subsoil allows the design and modeling of systems capable of taking advantage of heat energy and reducing the environmental impact produced by conventional sources.Fil: Carro Pérez, Magalí Evelín.

Exposición del público a los campos electromagnéticos de radiofrecuencia en estaciones del tren subterráneo de la Ciudad de Buenos Aires

En paralelo al incremento sostenido de las telecomunicaciones inalámbricas a nivel mundial ha surgido, en los ciudadanos, la preocupación referente a los eventuales efectos nocivos para la salud que pudieran ser derivados de la exposición a las radiofrecuencias utilizadas por estos servicios. En consecuencia, explorar nuevos y distintos escenarios, y obtener datos sobre los niveles de exposición existentes allí, suministra información para responder a esta preocupación. Este trabajo identifica a las estaciones de subterráneo con instalaciones de telefonía celular como un nuevo escenario y estudia la exposición del público a las radiofrecuencias existentes allí. Los resultados demuestran que el 99,89 % de los niveles medidos son inferiores a 0,2 mW/cm2 (Límite ICNIRP para exposición no controlada). Se destacan como conclusiones que los niveles en las estaciones de subterráneo deben verificarse y son comparables a los existentes en azoteas de edificios con antenas de telefonía celularFil: Vanella, Oscar Rodolfo.

Weaning from mechanical ventilation in intensive care units across 50 countries (WEAN SAFE): a multicentre, prospective, observational cohort study

Background Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. Methods WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventilator, successful weaning as no reintubation or death within 7 days of extubation, and weaning eligibility criteria based on positive end-expiratory pressure, fractional concentration of oxygen in inspired air, and vasopressors. The primary outcome was the proportion of patients successfully weaned at 90 days. Key secondary outcomes included weaning duration, timing of weaning events, factors associated with weaning delay and weaning failure, and hospital outcomes. This study is registered with ClinicalTrials.gov, NCT03255109. Findings Between Oct 4, 2017, and June 25, 2018, 10 232 patients were screened for eligibility, of whom 5869 were enrolled. 4523 (77·1%) patients underwent at least one separation attempt and 3817 (65·0%) patients were successfully weaned from ventilation at day 90. 237 (4·0%) patients were transferred before any separation attempt, 153 (2·6%) were transferred after at least one separation attempt and not successfully weaned, and 1662 (28·3%) died while invasively ventilated. The median time from fulfilling weaning eligibility criteria to first separation attempt was 1 day (IQR 0–4), and 1013 (22·4%) patients had a delay in initiating first separation of 5 or more days. Of the 4523 (77·1%) patients with separation attempts, 2927 (64·7%) had a short wean (≤1 day), 457 (10·1%) had intermediate weaning (2–6 days), 433 (9·6%) required prolonged weaning (≥7 days), and 706 (15·6%) had weaning failure. Higher sedation scores were independently associated with delayed initiation of weaning. Delayed initiation of weaning and higher sedation scores were independently associated with weaning failure. 1742 (31·8%) of 5479 patients died in the intensive care unit and 2095 (38·3%) of 5465 patients died in hospital. Interpretation In critically ill patients receiving at least 2 days of invasive mechanical ventilation, only 65% were weaned at 90 days. A better understanding of factors that delay the weaning process, such as delays in weaning initiation or excessive sedation levels, might improve weaning success rates

Patterns of oral anticoagulant use and outcomes in Asian patients with atrial fibrillation: a post-hoc analysis from the GLORIA-AF Registry

Background: Previous studies suggested potential ethnic differences in the management and outcomes of atrial fibrillation (AF). We aim to analyse oral anticoagulant (OAC) prescription, discontinuation, and risk of adverse outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods: From the GLORIA-AF Registry Phase II-III (November 2011-December 2014 for Phase II, and January 2014-December 2016 for Phase III), we analysed patients according to their self-reported ethnicity (Asian vs. non-Asian), as well as according to Asian subgroups (Chinese, Japanese, Korean and other Asian). Logistic regression was used to analyse OAC prescription, while the risk of OAC discontinuation and adverse outcomes were analysed through Cox-regression model. Our primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). The original studies were registered with ClinicalTrials.gov, NCT01468701, NCT01671007, and NCT01937377. Findings: 34,421 patients were included (70.0 ± 10.5 years, 45.1% females, 6900 (20.0%) Asian: 3829 (55.5%) Chinese, 814 (11.8%) Japanese, 1964 (28.5%) Korean and 293 (4.2%) other Asian). Most of the Asian patients were recruited in Asia (n = 6701, 97.1%), while non-Asian patients were mainly recruited in Europe (n = 15,449, 56.1%) and North America (n = 8378, 30.4%). Compared to non-Asian individuals, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian patients (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively), but higher in the Japanese subgroup. Asian ethnicity was also associated with higher risk of OAC discontinuation (Hazard Ratio [HR] and [95% CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95% CI]: 0.86 [0.76-0.96]). Among the exploratory secondary outcomes, Asian ethnicity was associated with higher risks of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding. Interpretation: Our results showed that Asian patients with AF showed suboptimal thromboembolic risk management and a specific risk profile of adverse outcomes; these differences may also reflect differences in country-specific factors. Ensuring integrated and appropriate treatment of these patients is crucial to improve their prognosis. Funding: The GLORIA-AF Registry was funded by Boehringer Ingelheim GmbH
