ABSTRACT

Introduction Simulation in neurosurgery is a growing trend in medical residency programs around the world due to the concerns there are about patient safety and the advancement of surgical technology. Simulation training can improve motor skills in a safe environment before the actual setting is initiated in the operating room. The aim of this review is to identify articles that describe Brazilian simulators, their validation status and the level of evidence (LoE). Methodology This study was conducted using the Preferred Reported Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A search was performed in the Medline, Scielo, and Cochrane Library databases. The studies were evaluated according to the Medical Education Research Quality Instrument (MERSQI), and the LoE of the study was established according to the classification system of the Oxford Centre for Evidence-Based Medicine (OCEBM), which has been adapted by the European Association of Endoscopic Surgery. Results Of all the studies included in this review, seven referred to validated simulators. These 7 studies were assigned an average MERSQI score of 8.57 from 18 possible points. None of the studies was randomized or conducted in a high-fidelity environment. The best evidence was provided by the studies with the human placenta model, which received a score of 2b and a degree of recommendation of 3. Conclusion Brazilian simulators can be reproduced in the different laboratories that are available in the country. The average MERSQI score of Brazilian studies is similar to the international average score. New studies should be undertaken to seek greater validation of the simulators and carry out randomized controlled trials.

ABSTRACT

Shiga toxin (Stx)-producing Escherichia coli (STEC) infections are implicated in the development of the life-threatening hemolytic-uremic syndrome (HUS). Despite the magnitude of the social and economic problems caused by HUS, no licensed vaccine or effective therapy is currently available for human use. Prevention of STEC infections continues being the most important measure to reduce HUS incidence. This is especially true for Argentina where HUS incidence among children is extremely high and shows an endemic pattern. The aim of this work was to investigate serologically adult staff of kindergartens in Buenos Aires city and suburban areas in order to detect possible carriers, and to educate personnel about good practices to reduce HUS transmission. We also assessed the microbiological quality of water and meal samples from the same kindergartens. We tested 67 healthy adults, 13 water supplies and 6 meals belonging to 6 public kindergartens. We analysed hand swabs for isolation of STEC and serum samples for the presence of antibodies against Stx and lipopolysaccharide (LPS) of O157 serogroup. We identified 46 Stx2-positive individuals, but only 7 for O157 LPS. No presence of STEC pathogens was detected in hands of staff, water or meal samples.


Las infecciones bacterianas con Escherichia coli productor de toxina Shiga (Stx) (STEC) están implicadas en el desarrollo del síndrome urémico hemolítico (SUH). A pesar de la magnitud del problema social y económico causado por el SUH, actualmente no existe un tratamiento específico o una vacuna eficaz para uso humano. Por lo tanto, la prevención de las infecciones por STEC es la tarea central para reducir la incidencia del SUH. Esto es especialmente cierto para Argentina en donde el SUH muestra un comportamiento endémico y presenta una incidencia extremadamente alta entre los niños. En efecto, la mediana de casos notificados en menores de 5 años para el periodo 2010-2015 fue 306, mientras que la tasa de notificación fue 8.5 casos cada 100 000 menores/año (http://www.msal.gob.ar/images/stories/boletines/boletin_integrado_vigilancia_N335-SE45.pdf). El objetivo de este trabajo fue analizar serológicamente al personal adulto de jardines de infantes de la ciudad de Buenos Aires y el área suburbana con el fin de detectar portadores, y brindarles formación sobre las buenas prácticas para reducir la transmisión de infecciones con STEC y así evitar el SUH. También se evaluó la calidad microbiológica de las muestras de agua y de la comida elaborada en los mismos jardines. Hemos estudiado 67 adultos, a través del hisopado de manos para la búsqueda de STEC y suero para la presencia de anticuerpos contra Stx y el lipopolisacárido (LPS) de serogrupo O157. También se analizaron 13 suministros de agua y 6 muestras de comida pertenecientes a 6 jardines de infantes públicos. Se identificaron 46 individuos positivos para Stx2, pero solo 7 para LPS-O157. No se detectó presencia de patógenos STEC en las muestras de las manos del personal, ni en los reservorios de agua o muestras de comida.

ABSTRACT

Se conocen los puntos precisos de intervención en la cadena epidemiológica para prevenir el Síndrome Urémico Hemolítico, pero las condiciones pueden variar entre distintas localidades. OBJETIVOS: Con este estudio se pretende mostrar la utilidad de un modelo de diagnóstico de situación que permite optimizar la implementación de un programa preventivo de educación comunitaria de tipo “formación de formadores” en dos municipios de la provincia de Buenos Aires, y una evaluación de procesos. MÉTODO: El diagnóstico incluyó el relevamiento de la situación socio-sanitaria, hábitos y costumbres alimentarios y detección de los problemas en la cadena de producción, comercialización y consumo de alimentos. La evaluación del proceso fue cuali-cuantitativa: número de talleres y de participantes, e indagación de fortalezas y debilidades del proceso. RESULTADOS: Los principales problemas encontrados fueron la carencia de agua potable y de manejo de las excretas en un gran porcentaje de la población y los deficientes controles bromatológicos y de mantenimiento de la cadena de frío en la provisión de carne y leche. Este diagnóstico permitió adaptar el programa a las condiciones específicas locales, elemento necesario para lograr una intervención eficaz. Se realizaron en total 26 talleres con la participación de 588 agentes. El material gráfico fue de gran utilidad para la comprensión de los contenidos docentes y todos los participantes de los talleres respondieron con gran motivación. Se logró el apoyo de las autoridades locales, lo que facilitó la ejecución del programa


The precise points of intervention in the epidemiological chain to prevent Hemolytic Uremic Syndromeare well known, although conditions may vary between different localities. OBJECTIVES: This study aims to show the usefulness of a situation diagnostic model to optimize the implementation of a preventive community education program type “training the trainers” in two municipalities in the province of Buenos Aires, and the evaluation of the process. METHODS: The diagnosis included a survey of the socio-sanitary conditions, food habits and identifying problem sin the chain of production, marketing and consumption of food. Process assessment was qualitative and quantitative: number of workshops and participants, and determination of strengths and weaknesses of the process. RESULTS: The main concerns were: lack of safe water and excreta management in a large percentage of the population, weak bromatological controls and maintenance of cold chainin providing meat and milk. This diagnosis allowed to adaptthe program to specific local conditions, which is necessary to achieve effective intervention. A total of 26 workshops involving 588 agents were carried out. The artwork was useful for the understanding of educational contents and all workshop participants responded with great motivation. The support from local authorities facilitated the implementation of the program
