RESUMO

ABSTRACT Objectives To describe means for disposing organic waste from bovine necropsies carried out on-farm, and to look for associated factors. Materials and Methods A cross-sectional study was carried out in 421 rural Veterinarians on the Province of Santa Fe, Argentina. Data were collected using a structured questionnaire. Data analysis included x2, Fisher's exact test, and Spearman's correlation. Results Ninety percent of respondents (n=381) performed necropsies. The most frequent practice was to leave the remains in the place where it was carried out or to take them to a specific site, while the least frequent was to cover them with calcium hydroxide and plastic membranes. The geographical region of professional practice was associated in various ways to waste management. These results show inconsistencies in the protocols for organic waste disposal under field conditions in the region under study. Conclusions It is important to encouraged during undergraduate studies both legal and biological knowledge on the consequences of inappropriate disposal of biopathogenic waste. Moreover, continuing education programs for graduates should include standardized protocols for the safe execution of these practices.

RESUMEN Objetivos Describir las formas de descarte del material orgánico remanente de necropsias de bovinos realizadas en campo y explorar factores asociados. Materiales y Métodos Se efectuó un estudio transversal en 421 médicos veterinarios rurales de la Provincia de Santa Fe, Argentina. Los datos fueron colectados utilizando un cuestionario estructurado. El análisis de los datos incluyó x2, test exacto de Fisher y correlación de Spearman. Resultados El 90,5 % de los encuestados (n= 381) realizaban necropsias. La práctica más frecuente fue dejar los restos en el lugar donde se efectuó la misma o llevarlos a la cava, mientras que la menos frecuente fue cubrirlos con hidróxido de calcio y membrana plástica. La región geográfica de ejercicio profesional estuvo asociada de maneras diversas con la adopción de dichas prácticas. Los resultados muestran inconsistencias en los protocolos de disposición de restos de necropsias en condiciones de campo en la región bajo estudio. Conclusiones Es importante incentivar durante los estudios universitarios el conocimiento legal y biológico de las consecuencias de una eliminación inapropiada de residuos biopatogénicos. Por otra parte, los programas de capacitación continua de los profesionales deberían incluir protocolos estandarizados para la ejecución segura de estas prácticas.

RESUMO

During World War II, many nations took part in the war. Among the supporters of the Alliance there was also Brazil. In August 1944, under the leadership of President Getúlio Vargas, Brazil declared war on Nazi Germany and took part in the Italian campaign by sending many troops to support the Allies in the Central Italy. Once the conflict was over, the deceased Brazilian soldiers were buried in Pistoia, a few kilometers from Florence. But only in 1960 the Brazilian government authorized the transfer of the dead soldiers to their homeland. Five years later, during the building of the Brazilian Military Votive Monument, still in the Pistoia cemetery, a last body was found but could not be identified: so he was buried as an "unknown soldier". In December 2012, the Brazilian Embassy in Italy asked for performing forensic genetics analysis for identification purposes on the remains of this last unknown Brazilian soldier. After almost 70 years a complete short tandem repeats (STR) profile was obtained, useful for any relatives searching. Key points: Identification of the last Brazilian Unknown Soldier buried in Italy.DNA analysis on 70 years old skeletal remains.Brazilian soldier's history during World War II.
