Importância da proteção da mesa de instrumentais cirúrgicos na contaminação intraoperatória de cirurgias limpas

OBJECTIVE: to compare the degree of bacterial contamination of surgical instrument tables used in clean surgical procedures, either protected with plastic fields, sterilized with ethylene oxide, or disinfected with 70% alcohol and 1% iodine solutions. This is a randomized clinical trial in which samples were collected from the surfaces of surgical instrument tables before and after each procedure. Microbiological analysis was performed to identify microorganisms and their respective antimicrobial resistance. RESULTS: Bacterial growth in the surgeries using sterilized plastic was 5.71% before and 28.6% after surgery and, 2.9% and 45.7% respectively in surgeries using disinfection with 70% alcohol and 1% iodine solutions; no statistical difference was found between the methods. CONCLUSION: both methods present similar protection, however, 70% alcohol and 1% iodine do not generate solid waste.El objetivo del estudio fue analizar el grado de contaminación bacteriana de la mesa de instrumentos quirúrgicos en dos casos, después del uso: cubierta protectora plástico de la mesa quirúrgica esterilizada con óxido de etileno o desinfección con solución de alcohol a 70% y yodo a 1%, en procedimientos quirúrgicos limpios. Se trata de un experimento clínico aleatorio, con recolección de muestras de las superficies de las mesas de instrumentos quirúrgicos, antes y después de cada procedimiento, con posterior análisis microbiológica para identificar los microorganismos y la resistencia antimicrobiana. En las cirugías en que el plástico esterilizado fue utilizado, el crecimiento bacteriano fue de 5,71% antes y 28,6% después de la cirugía, en cuanto que en las desinfecciones con solución de alcohol a 70% y yodo a 1%, el crecimiento fue de 2,9% antes y 45,7% después, lo que indica que no hubo diferencia significativa entre los métodos empleados. Los dos métodos tienen poder de protección semejante, considerando que el alcohol a 70% y yodo a 1% no generan residuos sólidos.OBJETIVO: analisar o grau de contaminação bacteriana da mesa de instrumentais cirúrgicos, após o uso de campo plástico esterilizado por óxido de etileno ou a desinfecção com solução de álcool a 70% e iodo a 1%, em procedimentos cirúrgicos limpos. MÉTODOS: Trata-se de experimento clínico randomizado, com coletas de amostras das superfícies das mesas de instrumentais cirúrgicos, antes e depois de cada procedimento, com posterior análise microbiológica para identificação dos microrganismos e sua resistência antimicrobiana. RESULTADOS: nas cirurgias em que o plástico esterilizado foi utilizado, o crescimento bacteriano foi de 5,71% antes e 28,6% após a cirurgia, enquanto que nas desinfecções com solução de álcool a 70% e iodo a 1%, o crescimento foi de 2,9% antes e 45,7% após, sem diferença significativa entre os métodos empregados. CONCLUSÕES: os dois métodos têm poder de proteção semelhante, considerando que o álcool a 70% e iodo a 1% não geram resíduos sólidos

The Influence of Incentive Programs on Executives’ Risk Perception

The balance between executive compensation and value added is a constant challenge for organizations, as well as an important key to minimize agency problems. This study aims to evaluate the relationship between term of payment and compensation variability and the executives’ risk perception, as well as their motivation to add value, using the agency theory and the executive compensation literature as references for the study. Quantitative methods were applied, by collecting primary data from 121 Brazilian executives who answered a survey regarding their company’s compensation program models and their risk perception. Study results showed that executives' risk perception, as well as their motivation to add value, have statistically significant relationship with the level of compensation variability. Statistically significant relationship was also found between individual characteristics, such as age and time working for the organization, and the executive’s risk perception.The balance between executive compensation and value added is a constant challenge for organizations, as well as an important key to minimize agency problems.

Deep Learning Brasil at ABSAPT 2022: Portuguese Transformer Ensemble Approaches

Aspect-based Sentiment Analysis (ABSA) is a task whose objective is to classify the individual sentiment polarity of all entities, called aspects, in a sentence. The task is composed of two subtasks: Aspect Term Extraction (ATE), identify all aspect terms in a sentence; and Sentiment Orientation Extraction (SOE), given a sentence and its aspect terms, the task is to determine the sentiment polarity of each aspect term (positive, negative or neutral). This article presents we present our participation in Aspect-Based Sentiment Analysis in Portuguese (ABSAPT) 2022 at IberLEF 2022. We submitted the best performing systems, achieving new state-of-the-art results on both subtasks.Comment: 11 pages, 3 figures, In Proceedings of the Iberian Languages Evaluation Forum (IberLEF 2022), Online.
