    Introducción: Las fundiciones de acero son sitios significativos de contaminación con procesos manuales de moldeo y desmoldeo, por lo que, la tecnología ha avanzado al moldeo utilizando resinas auto fragantes. En el presente trabajo se aplica la metodología de Análisis de ciclo de vida (ACV) para evaluar los impactos ambientales en un proceso de fundición sujeto a esta inversión tecnológica. Objetivo: Evaluar el impacto ambiental de una propuesta tecnológica de moldeo en una fundición de acero. Materiales y Métodos: Se evaluaron e inventariaron los flujos de entradas y salidas de las mezclas de arena, gases y residuos sólidos en los procesos de moldeo tradicional y moldeo químico para la producción de una tonelada de acero, como unidad funcional. Se utilizó el software SimaPro 8.0 para obtener los resultados del ACV. Resultados y Discusión: Los resultados demuestran la factibilidad económica y ambiental del moldeo químico. En el análisis se constató que la arena de retorno, es la materia prima de mayor beneficio a las categorías de impacto siendo las más favorecidas el cambio climático a la salud humana y la formación de partículas que inciden en la salud, los ecosistemas y los recursos naturales. Conclusiones: La metodología ACV cuantifica los impactos ambientales de la producción de acero y justifica la factibilidad económico-ambiental del moldeo químico verificando que la arena de retorno, es la materia prima con mayor aporte a las categorías de impacto y favorece, como producto evitado que se recicla, en la nueva tecnología las categorías ambientales y de daño

    Background: colorectal cancer screening by occult blood test is an opportunity for the early diagnosis and prompt treatment of one of the primary causes of death because of malignant tumors in Cuba and in the world.Objective: to determine the results of the application of occult blood test screening in feces samples processed in the ultra-micro-analytic laboratory of Dr. Ernesto Guevara de la Serna Teaching General Hospital in Las Tunas province during 2015.Methods: the information about the patients processed in the trial: age, origin, gender, cause of indication, symptoms and personal history were taken from the tests registration in the ultra-micro-analytic laboratory.Results: a month average of 39 was found in 271 samples studied and positivity in 18,8 %. Abdominal pain, bleeding or changes in bowel habits resulted in a positivity that always exceeded 20 %. Only the 5,2 % of the tests were consistent with the investigation and none of those cases was positive. 69,9 % of the individuals studied came from the outpatient consultation and there were only 8 hospitalized patients. Several deficiencies were detected in the trial requests, related to the completion of the clinical data.Conclusions: there has not been made good use of occult blood test in feces in Las Tunas province.</p

    Peripheral inflammatory markers contributing to comorbidities in autism

    This study evaluates the contribution of peripheral biomarkers to comorbidities and clinical findings in autism. Seventeen autistic children and age-matched typically developing (AMTD), between three to nine years old were evaluated. The diagnostic followed the Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DMS-IV) and the Childhood Autism Rating Scale (CARS) was applied to classify the severity. Cytokine profile was evaluated in plasma using a sandwich type ELISA. Paraclinical events included electroencephalography (EEG) record. Statistical analysis was done to explore significant differences in cytokine profile between autism and AMTD groups and respect clinical and paraclinical parameters. Significant differences were found to IL-1 , IL-6, IL-17, IL-12p40, and IL-12p70 cytokines in individuals with autism compared with AMTD (p < 0.05). All autistic patients showed interictalepileptiform activity at EEG, however, only 37.5% suffered epilepsy. There was not a regional focalization of the abnormalities that were detectable with EEG in autistic patients with history of epilepsy. A higher IL-6 level was observed in patients without history of epilepsy with interictalepileptiform activity in the frontal brain region, p < 0.05. In conclusion, peripheral inflammatory markers might be useful as potential biomarkers to predict comorbidities in autism as well as reinforce and aid informed decision-making related to EEG findings in children with Autism spectrum disorders (ASD)
