Abstract: objective: to compare the results of nutritional assessment of children and adolescents under 18 years of age using the who growth standards and the cut-off points proposed by the resolution 2121 of 2010 of the social security ministry of colombia. materials and methods: we evaluated the nutritional status by using the indicators height/age and body max index (bmi) in children and adolescents under 18 years of age and weigh/height in children under five belonging to 2719 rural and urban households in medellin. they were sampled in the study food and nutritional profile of medellin 2010 conducted by the municipal government. results: we found lower prevalence rates of adequate weight/height and bmi in children less than five years of age using the colombian standards as compared to the who standards. bmi for children over 5 years of age behaved similarly. the difference is explained for using different cut-off points and inclusion of new nutritional risk categories. conclusions: for population-based studies may not be required to introduce the categories of nutritional risk and to change the cut-off points for overweight and obesity set up by the who standards given that they are more rigorous than others parameters for evaluating these two nutritional conditions. related to individual follow-ups it is important to complement anthropometric measure evaluation with social aspects, family history, and rearing habits in children with bmi between 1 and 2 standard deviations.

Revista chilena de infectología , 2012,
Abstract: Introducción: Las enfermedades transmitidas por alimentos (ETA) han aumentado considerablemente. Objetivo: Reportar un grave brote de ETA destacando la importancia de la notificación precoz para la activación del sistema de vigilancia epidemiológica. Resultados: Durante febrero de 2011 se observó un brote de Salmonella Enteritidis. Un 31,6% de los casos fueron atendidos en un mismo servicio de urgencia, donde todos requirieron la administración de fluidos endovenosos y 41,7% fueron hospitalizados por deshidratación grave. El 45,5% de los casos necesitó de una segunda consulta para ser diagnosticados correctamente. Discusión: La identificación de pacientes integrantes de un brote de ETA es difícil en los servicios de urgencia y los médicos sub-reportan los casos, retrasando al sistema de vigilancia epidemiológica. Conclusiones: Junto con brindar un adecuado tratamiento, los médicos deben estar capacitados para reconocer las ETA y comunicar tempranamente la sospecha de un brote para prevenir nuevos casos en la comunidad.

Abstract: We analyzed over 300 SNP in the genome of grapevine using a re-sequencing strategy in a selection of 11 genotypes. Among the identified polymorphisms, we selected 48 SNP spread across all grapevine chromosomes with allele frequencies balanced enough as to provide sufficient information content for genetic identification in grapevine allowing for good genotyping success rate. Marker stability was tested in repeated analyses of a selected group of cultivars obtained worldwide to demonstrate their usefulness in genetic identification.We have selected a set of 48 stable SNP markers with a high discrimination power and a uniform genome distribution (2-3 markers/chromosome), which is proposed as a standard set for grapevine (Vitis vinifera L.) genotyping. Any previous problems derived from microsatellite allele confusion between labs or the need to run reference cultivars to identify allele sizes disappear using this type of marker. Furthermore, because SNP markers are bi-allelic, allele identification and genotype naming are extremely simple and genotypes obtained with different equipments and by different laboratories are always fully comparable.Grapevine (Vitis vinifera L.) is one of the most valuable horticultural crops in the world. Many of the widely cultivated varieties are very ancient genotypes that have been vegetatively multiplied for centuries and spread worldwide. In many places the same genotypes were re-named leading to synonyms (different names for the same variety) as well as homonyms (different varieties identified under the same name). Currently, there is a large but imprecise number of grapevine varieties in the world (several thousands, [1]): This number could likely be reduced once all varieties are properly genotyped and compared.When genetic identification is taken into account, two goals have to be fulfilled: i) the availability of a large enough number of polymorphic markers; and ii) the existence of public genotype databases allowing for compari
Posgrados sobre desarrollo en América Latina: origen y evolución
Carreo,Claudia Inés;
Educación y Educadores , 2011,
Abstract: the focus of this study is on postgraduate education in development in the latin american context. the objective is to show how postgraduate courses of this type emerge in latin america and their contents, as well as what they teach and how. a qualitative approach was used to develop the study, particularly a content analysis of written documents coupled with in-depth interviews of experts and professors. the principal findings show a strong emphasis on the teaching of development understood as economic growth, with special emphasis on the models necessary to encourage it. however, there also is evidence that the human development perspective has begun to gain importance. it is a view in which economic development is an aspect, but not the only one. generally speaking, postgraduate courses in development place a priority on local-scale studies. however, it is essential to go beyond these analyses to other scales and in the direction of more multidimensional studies.
Más allá de la tarea: pistas para una redefinición del concepto de Motivación Escolar
Valenzuela Carreo, Jorge;
Educa??o e Pesquisa , 2007, DOI: 10.1590/S1517-97022007000300002
Abstract: the work investigates the various approaches to the issue of motivation, and in this context observes and questions the idea of school motivation that emphasizes the role of tasks, turning the completion of the latter into the motivation to carry out the activities required by the school, instead of stressing the motivation to learn. the author indicates some aspects or variables that should be considered when building up school motivation. these pointers are specifically related to the incorporation inside this construct of the reasons pupils have to attend school, and which give meaning to their school learning, thereby complementing the variables associated to the tasks. thus, without forgetting that the students must put effort into the completion of the tasks designed for their learning, we should recall the essentials of school motivation, namely, that which drives, conducts and sustains the students' efforts, and triggers cognitive resources to learn. a learning which, as it is consensual among educators, must not limit itself to the mere acquisition of information, but should be processed. the knowledge constructed (pozo, 2003) is thus made meaningful (ausubel, 1978) and deep (beas, 1994; beas et al., 2001).
Exigencia académica y atribución causal: ?qué pasa con la atribución al esfuerzo cuando hay una baja significativa en la exigencia académica?
Valenzuela Carreo,Jorge;
Educere , 2007,
Abstract: the empirical evidence which would support the thought that a significative low academic demand in schools would have negative efects over effort attribution from students, as explicative feature of academic achievement, is reported in this communication. the data was collected from a doctoral thesis and is treated as a fortune finding, since the significative low academic demand circumstances found were not intentional. the context from which this data was found is reported, the results are shown and the evidences are discussed
El método Delphi: cuando dos cabezas piensan más que una en el desarrollo de guías de práctica clínica
Carreo Jaimes,Marisol;
Revista Colombiana de Psiquiatría , 2009,
Abstract: introduction: clinical practice guidelines should be based on the best available evidence. other considerations beyond the evidence are therefore needed in order to formulate specific and applicable recommendations for clinical practice. objective: the aim of this paper was to review the delphi technique for achieving consensus among experts in the development of evidence-based guidelines. method: this paper reviews the structuring necessary for obtaining consensus in the process of formulating recommendations for clinical guidelines. conclusion: the delphi technique is a method for collecting opinions on a particular research question. it is based on the premise that pooled intelligence enhances individual judgment and captures the collective opinion of a group of experts without them being physically present.

Carreo Lara,Eduardo;
Estudios Políticos , 2012,
Abstract: for over forty years, the soccer was considered in south africa an important scenario in the struggle for freedom, obtaining the anti-apartheid movement symbolic, but crucial achievements in this sphere when the local federation was suspended by fifa from all international competitions until 1992. once democracy, the soccer -like other sports- has been considered an instance of encounter and reconciliation in a society marked by racial cleavages, thus awarding the fifa world cup was hailed by the south africa's people and the african continent as a great victory that raised expectations about the benefits of this event to improve the quality of life for millions of people. therefore, the purpose of this article is to analyze the political, economical and social motivations behind the organization of fifa world cup south africa 2010. it is an explanatory study supported by the review of secondary sources and official data provided by the south african government aimed at estimating the diplomatic implications of an event that clearly surpassed the purely sporting.
El Alcohol de grano de Valdivia en Araucanía y las Pampas
Carreo Palma,Luis;
Universum (Talca) , 2005, DOI: 10.4067/S0718-23762005000200009
Abstract: the topic of the alcohol trafic in the araucania and the pampas has been poorly studied. representing an informal trade, functioning on the edge of the chilean and argentinian economies, not ruled by the laws of both states, with the particularity of the absence of money and just the use of speech as a way of exchanging products and making deals. considering this type of trade, there are not many oficial or private documentary sources. the only one consists in the diaries of the travellers visiting and discovering the araucania and the pampas during the xviii and xixth centuries. considering that these are the only sources, they nevertheless represent a valorous source of information and knowledge. during the xviii and xixth centuries, the number of travellers was important, from many diferent nationalities, they came into the araucania and the pampas and their diaries speak about there continuous meetings with aguardiente traders coming from valdivia, penetrating the araucania, and crossing the cordillera towards the pampas in order to exchange alcohol with cattle. all these travellers agree that the alcohol consumed in the south araucania and the pampas mainly comes from the grain alcohol fabrics of valdivia, owned by german settlers. the goal of this paper is to know the grain alcohol trade in the economical region of valdivia, the araucania and the pampas during the segond half of the xixth century
