Abstract: Introducción: El control de la natalidad y el descenso de la mortalidad han desencadenado un envejecimiento demográfico, por lo que en algunos casos no es posible determinar con exactitud la estatura o el peso, careciendo de utilidad los indicadores nutricionales. Objetivo: Relacionar el índice de masa corporal (IMC) con el perímetro de pantorrilla y la fuerza muscular medida por la dinamometría de mano dominante y no-dominante. Métodos: Se estudiaron 60 adultos mayores de 60 a os, con capacidad funcional de autovalencia, los adultos pertenecían al círculo de Carabineros de Chile en retiro de la ciudad de Chillan en la VII Región. Los datos antropométricos y la dinamometría se determinaron de acuerdo a las técnicas establecidas por la OMS. Se utilizó el coeficiente de correlación y Anova para determinar la asociación entre las variables. Resultados: Se observó una relación negativa débil entre ambas dinamometrías con el IMC; r = -0.19, dominante (p 0.332) y no dominante r = -0.11 (p 0.806), pero se encontró una correlación positiva de carácter mediana, entre el perímetro de pantorrilla y el IMC, r = 0.64 (p<0.001). Conclusiones: Los datos aportados evidencian la utilidad del perímetro de pantorrilla como indicador del estado nutricional en los sujetos de estudio, no así la dinamometría de mano.

Revista Chilena de Nutricíon , 2002,
Abstract: La deficiencia de hierro es la carencia nutricional más frecuente y la principal causa de anemia en el ni o. En un estudio a escala nacional (1974-1975) la prevalencia de anemia en preescolares fue de 18,8%. Para evaluar la nutrición de hierro, se seleccionaron 96 ni os sanos (2 a 5 a os) de la comuna La Pintana. Previo consentimiento informado, se obtuvo una muestra de sangre para medir hemoglobina, volumen corpuscular medio, protoporfirina libre eritrocitaria y ferritina sérica. Ninguno de los ni os presentó anemia ferropriva o eritropoyesis deficiente en hierro. Sólo un 5,2% de los sujetos tenía una depleción de los depósitos de hierro. 99% y 69% de los ni os consumían diariamente pan y leche fortificada (Leche Purita Cereal). Es altamente probable que la mejoría de la nutrición de hierro de los ni os se deba al consumo de alimentos fortificados con hierro: harina de trigo y la Leche Purita Cereal distribuida por el Programa Nacional de Alimentación Complementaria Iron deficiency is the single most common nutritional disorders worldwide and the main cause of anemia in infancy and childhood. The prevalence of anemia in a Chilean national sample of preschool children was 18.8% (1974-1975). Ninety-six healthy children aged 2 to 5 years from La Platina were selected to evaluate iron nutritional status. After informed written consent was obtained from the parents, a venous sample was drawn to measure hemoglobin, mean corpuscular volume, free erythrocyte protoporhyrin and serum ferritin. None of the children presented iron deficiency anemia or iron-deficient erythropoiesis, and only 5.2% of the subjects had iron depleted stores. Ninety-nine and 69% of the children consumed daily bread and iron fortified milk (Leche Purita Cereal), respectively. It is highly likely that the iron fortification of wheat flour and the milk distributed by the National Complementary Food Program has improved iron nutrition status of children

Abstract: probiotic bacteria are defined as live microorganisms that administered as a diet supplement can cause modifications in the microbiota associated with the gastrointestinal tract of the host and generate beneficial effects such as an increase in the food intake conversion, disease resistance and water quality. during the last decade, its application in shrimp farming has become frequent since several commercial products designed for this purpose have emerged. at the same time, although there are a number of scientific articles published on the subject, it is evident that there is a lack of studies oriented to understand the probiotics working mechanisms and to establish the protocols for its implementation, taking into account critical factors such as the stage of cultivation, culture density and dosage in relation to the shrimp immune defense mechanisms and presence of potentially pathogenic organisms. this paper aims to review the most prominent publications regarding the use of probiotics in aquaculture, particularly in shrimp farming, since its use seems to be the alternative with better perspectives to the indiscriminate use of antibiotics that cause problems such as the emergence of multi-resistant bacterial strains that could alter the ecosystems near acuaculture sites and even affect consumer health.

Abstract: Mussels are one of the most cultivated and commercialized bivalves worldwide and in southern Chile its culture represent an important economic activity. The species identification within the Mytilus genera, by morphological features, is unreliable, so we used a polymorphism RFLP in the gene encoding the polyphenolic adhesive protein as a species-specific genetic marker to describe Mytilus species diversity in southern Chile, and evaluate possible applications in traceability, food quality and safety. Using Me 15-16 marker most mussels were M. chilensis, finding no other pure individuals; however, putative hybrids of M. chilensis x M. trossulus and M. chilensis x M. galloprovincialis were detected. There was no evidence of M. edulis. The presence of the M. trossulus allele, faraway from its distribution area, demands further analysis with different genetic markers to allow a better understanding of its origin. In addition, the correspondence between markers that distinguishes northern from southern hemisphere M. galloprovincialis, with those who discriminates between M. chilensis and M. galloprovincialis would contribute to the taxonomic status of Chilean blue mussels. In Chile, the genetic composition of Mytilus indicates that geographical origin of mussels and its traceability cannot be established merely from the identification of the species. The use of other markers would be required. Los mejillones son una de las especies de bivalvos más cultivadas y comercializadas, en el sur de Chile donde su cultivo representa una actividad económica importante. La identificación de la especie dentro del género Mytilus, basada en las características morfológicas no es confiable por lo que se utilizó un polimorfismo RFLP en el gen que codifica la proteína adhesiva polifenólica como marcador genético específico de la especie para describir la diversidad de especies Mytilus en el sur de Chile, y evaluar posibles aplicaciones en trazabilidad, calidad e inocuidad de los alimentos. Usando el marcador Me 15-16, la mayoría de los mejillones fueron M. chilensis, no se encontraron individuos puros de otras especies. Sin embargo, se detectaron híbridos putativos M. chilensis x M. trossulus y M. chilensis x M. galloprovincialis. No se encontró evidencia de M. edulis. La presencia del alelo de M. trossulus, lejos de su área de distribución, requiere de análisis posteriores con diferentes marcadores genéticos para entender su origen. Además, conocer la correspondencia entre marcadores que distinguen M. galloprovincialis del hemisferio norte y sur con aquellos que discriminan

Abstract: Introducción El aumento de la actividad física es uno de los componentes más importantes de un estilo de vida saludable vinculándose a beneficios físicos y mentales. La inactividad física aumenta la frecuencia y la duración de las incapacidades laborales lo cual presupone implicaciones desfavorables para el trabajador, para la empresa y para la sociedad. Objetivo Configurar el desempe o diferenciado del nivel de actividad física por unidad de trabajo pre y posintervención con pausas activas en funcionarios públicos en Chillán, Chile. Métodos Investigación descriptiva, exploratoria. Se aplicó el Cuestionario Internacional de Actividad Física formato corto, antes y después de la intervención con pausas activas en los mismos individuos, para medir el nivel de actividad física. Las pausas activas fueron de 15 minutos dos veces por semana, en el lugar de trabajo y se apoyaron en estrategias comunicacionales para fomentar la actividad física. Resultados Los datos revelaron que hubo una diferencia significativa después de la intervención, ya que aumenta el nivel de actividad física (t=-1,391) con el 95 % de nivel de confianza. Conclusiones Las pausas activas aumentan el nivel de actividad física de los usuarios, se establece un desempe o diferenciado pre y posintervención, y no se establece relación de dicho desempe o por unidad de trabajo. Introduction The increased physical activity is one of the most important elements of a healthy lifestyle that renders physical and mental benefits. Lack of physical activity increases frequency and duration of working disabilities leading to unfavourable implications for the worker, the company and the society as a whole. Objective To shape the differentiated performance of the level of physical activity per working unit in the public officials from Chillán, Chile before and after the intervention with active breaks. Methods Exploratory descriptive intervention. The short version of the International Questionnaire of Physical Activity was applied before and after the intervention with active pauses to the same individuals, in order to measure the level of physical activity. The active pauses took 15 minutes twice a week at the workplace, and they were based on communication strategies to promote physical activity. Results Data yielded that there is significant difference after the intervention, since the level of physical activity increases (t=-1,391), with 95% CI. Conclusions The active breaks increase the level of physical activity of the users; differentiated performance before and after intervention is established and

Abstract: La falta de garantías al solicitar un crédito, la poca información donde recurrir a solicitarlo y las diferentes formas de exclusión a los servicios financieros, coloca a las personas que pertenecen al sector rural como los más vulnerables para acceder a estos servicios. A nivel internacional se han generado diversos modelos que permiten el acercamiento de financiamiento al sector. El objetivo de la presente investigación es entender cuáles son los principales problemas que enfrentan los productores al solicitar un crédito, averiguar si ven al crédito como una fuente de financiamiento y realizar recomendaciones que permitan ayudar a mejorar dicha situación. En el municipio de Salinas, San Luis Potosí, México, es una zona con características que pueden facilitar la generación de proyectos productivos, si se contara con un esquema de financiamiento. Durante el 2008, se aplicaron 186 encuestas y se analizaron estadísticas nacionales. Los resultados mostraron que no hay cultura financiera, los productores no tienen información necesaria, de quién ofrece los créditos o dónde invertir sus recursos; a la banca comercial no le interesa el impacto de desarrollo que puedan tener sus créditos; el crédito de avío es el más solicitado. Las conclusiones se alan que la situación actual en el municipio respecto al crédito, es la misma que en cualquier nivel, por tanto es importante articular modelos de financiamiento, que consideren al crédito como motor para el desarrollo, permitiendo así la generación de oportunidades de empleo y autoempleo. The lack of guarantees when applying for a loan, the little information on where to file for one and the different forms of exclusion from financial services leaves people who belong to the rural sector as some of the most vulnerable in terms of access to these services. At an international scale, several models have been developed that help people in this sector gain more access to funding. This aim of this investigation was to understand which the main problems are that farmers face when applying for a loan, to find out if they see the loan as a source of funding and to make recommendations to help improve this situation. The municipal area of Salinas, San Luis Potosí, Mexico, is an area with characteristics that can facilitate the creation of farming projects, if there was a funding scheme. In 2008, 186 surveys were conducted and national statistics were analyzed. Results showed that there is no financial culture, farmers lack crucial information on who offers credits or where to invest; commercial banking corporations are unc
