Premisas de la tautología autoinmune en la esclerosis múltiple

La esclerosis múltiple (EM) es una enfermedad desmielinizante del sistema nervioso central. Varias características de la EM son comunes a muchas enfermedades autoinmunes, como la mayor prevalencia en las mujeres (razón mujer:hombre 3:1), mecanismos fisiopatológicos comunes, heterogeneidad clínica, factores ambientales, herencia poligénica moderada, susceptibilidad génica, co-ocurrencia de diferentes enfermedades autoinmunes en un individuo y en los miembros de la familia, y respuesta a la terapia inmunosupresora. El objetivo de este estudio es evaluar la EM como una enfermedad parte de la tautología autoinmune. Metodología Estudio analítico de corte transversal con 201 pacientes del Centro de Estudio de Enfermedades Autoinmunes (CREA) pertenecientes a regiones de Antioquia y Cundiboyaca, con diagnóstico definido de Esclerosis múltiple por medio de los criterios de Mc Donald. Resultados La poliautoinmunidad (OR 13.445 (1.772–102.009), la autoinmunidad familiar (OR 2.164(1.085-4.316), la región ( OR 2,891 (1.31-6.40), los cursos progresivos (OR 4.695-5.984) de esclerosis múltiple se encontraron significativamente asociados a la discapacidad y el género. Discusión Las características comunes de la esclerosis múltiple con otras enfermedades autoiunmunes, soportan la teoría del origen comun de estas condiciones.

Determinantes sociales de la enfermedad diarreica aguda en niños menores de 5 años en países en desarrollo

Antecedentes: Cada año hay 2,5 billones de casos de diarrea en menores de 5 años y 1,3 millones de estos niños mueren; lo que constituye a la EDA como segunda causa de muerte en este grupo de edad Metodología: Análisis transversal transnacional multinivel de la Encuesta DHS y el Banco Mundial en 348.706 niños de 40 países Resultados: Prevalencia de EDA 14%. Inequidad (OR=1.335; IC 95% 1.117-1.663) y bajos ingresos en las naciones (OR=1.488; IC 95% 1.024-2.163) presentaron asociación con EDA. Vivir en un país pobre aumenta la asociación entre el índice de riqueza del hogar y EDA (OR=1.0961; IC 95% 1.003-1.207) y la asociación entre no educación de la madre y EDA (OR=1.310; IC 95% 1.035-1.601). Otros factores asociados con EDA fueron sexo femenino, (OR=0.922; IC 95% 1.900-0.944), edad de niño (OR=0.978; IC 95% 0.978-0.979), vacunación (OR=0.821; IC 95% 0.799-0.843), peso normal al nacer (OR=0.879; IC 95% 0.834-0.926), edad de la madre (OR=0.987; IC 95% 0.985-0.989), no educación de la madre (OR=1.416; IC 95% 1.283-1.564), madre trabajadora (OR=1.136; IC 95% 1.106-1.167), embarazo deseado (OR=0.774; IC 95% 0.753-0.795), familia nuclear (OR=0.949; IC 95% 0.923-0.975) e índice de riqueza del hogar (OR=0.948; IC 95% 0.921-0.977) Conclusiones: La desigualdad y los bajos ingresos de los países desarrollados se asocian con EDA, independientemente de las características del niño, la mamá o el hogar. El gasto en salud no presenta asociaciones con EDA. Esto se debe considerar en las campañas de salud pública orientadas al manejo de la EDA.

Building WF16: construction of a PPNA pisé structure in Southern Jordan

The Pre-Pottery Neolithic A (PPNA) period in Southwest Asia is essential for our understanding of the transition to sedentary, agricultural communities. Developments in architecture are key to understanding this transition, but many aspects of PPNA architecture remain elusive, such as construction techniques, the selection of building materials, and the functional use of space. The primary aim of the research described within this contribution was to build a PPNA-like structure in order to answer questions about PPNA architecture in general, while specifically addressing issues raised by the excavation of structures at the site of WF16, Southern Jordan. The second aim was to display a ‘PPNA’ building to visitors in Wadi Faynan to enhance their understanding of the period. The experimental construction based on one of the WF16 structures showed that 1) required materials can be acquired locally; 2) a construction technique using mud layers as described in this paper was likely used; 3) flat, or very slightly dome-shaped, roofs are functional and can also be used as a solid working platform; 4) the WF16 small semi-subterranean buildings appear inappropriate for housing a nuclear family unit.

Em busca de um modelo brasileiro de ciclo de vida familiar para segmentação de mercado

Este trabalho apresenta uma revisão dos principais modelos de ciclo de vida para posteriormente discutir a necessidade de um modelo específico para o ambiente brasileiro. Apesar de toda discussão sobre a crise na instituição família em função das amplas mudanças ocorridas na sociedade contemporânea, tais como o aumento dos domicílios unipessoais, das famílias chefiadas por mulheres, da média de idade ao se casar, de casais que convivem no mesmo domicílio sem necessariamente estarem casados, da participação da mulher no mercado de trabalho e do crescente poder de compra dos domicílios, o conceito "família" vem se flexibilizando para refletir as transições da rígida estrutura familiar nuclear para novos modelos familiares e os estilos de vida associados a eles. O desafio passa a ser um olhar minucioso para as necessidades específicas desta diversidade de arranjos familiares para uma melhor compreensão dos seus desejos e motivações, bem como as mudanças no decorrer dos vários estágios do ciclo de vida. O presente estudo procurou explorar o construto ciclo de vida familiar como uma importante ferramenta de segmentação, a partir da definição de padrões de consumo de acordo com os principais eventos da vida do individuo e da família. Para verificar a utilidade do modelo desenvolvido, será apresentado um teste feito a partir dos micro dados de uma pesquisa feita pelo Instituto Brasileiro de Geografia e Estatística em 2002 e 2003. Uma das grandes contribuições deste trabalho é o esforço em desenvolver uma teoria de Marketing, na área de segmentação de mercados, ancorada na realidade brasileira, ao invés de simplesmente copiar modelos desenvolvidos em outros países.

Mulher chefe de família, na cidade de Aracaju:dominação e poder

The research was focada in the feminine head of family, the City of Aracaju and its impacts in the nuclear familiar nucleus. Considering that, the papers of the men are in general, not valued and rewarded that the papers of the women in almost all the cultures. The women generally load the responsibility to take care of of the children and the domestic work, while the men traditionally are born with the responsibility to support the family. However, we find changes in this mainly north-eastern scene and, where through quantitative research, already one evidenced that they are majority as family support, therefore, we observe the construction of social identities of the women family heads and uncurling of the adaptativos aspects, the existing mechanism between domination and power, in the familiar nucleus. The impacts in the family if had change in the social relation for them to be family heads. One is about qualitative research that has left of the construction of a theoretical landmark, analyzing given of bibliographical sources and from interviews with women family heads, power to observe the forms of joints in the nuclear families, as they deal with the power to decide power, the financial power, the fragility, the domination and the influences of the traditional models. Analyzing the familiar relations between the woman, the children and the spouse, searching the excellent questions for the briefing of the thematic one, demystifying the dichotomy between the mother/wife and woman head of family in the residential environment

Maternidade na adolescência: significados e repercussões

From evidence of an existing divergence of opinion among professionals and adolescents using the prenatal and delivery services at a Public Health Unit, aimed to study meanings and consequences of adolescent motherhood among 26 adolescent mothers living in Felipe Camarão, low income district of Natal, capital do Estado do Rio Grande do Norte. Living in a peripheral neighbourhood with a high rate of adolescent mothers in relation to the total new-born, those girls, with offspring among 8 and 12 months age, during interview and focus groups, expressed a different appreciation of their experience than the hegemonic idea among professionals that considers pregnancy and motherhood as unwanted or undesired. With age among 15 and 20 years old, having 53,8% initiated sexual activity before being 15 years old, revealed that the pregnancy was desired in 73,1% of cases, but showing at the same time a social context marked by strong gender oppression and lack of opportunities as consequence of social class deprivation. Life projects, almost always limited to the constitution of a traditional nuclear family, with a purveyor father and care giver mother, appears with very limited possibilities: 46,2% already lived with her partner before becoming pregnant and for 50% of the participants, the birth of the child did not provoke changes in plans and projects. Lack of economical recourses and precarious public services available, together with an idealized maternity role seems to produce extra apprehension among those girls, resulting in frustration and disillusion. As a fact, 92,3% of those adolescents would recommend other adolescent to postpone the maternity project

Saúde da Família: O desafio de uma atenção coletiva

The Family Health Strategies, incorporated by the Ministry of Health in 1994, has consolidated the national policy of health care that has as its main care focus the family. In this model, this institution constitutes the first object of attention, understood from its environment and interaction. In recent decades, the Brazilian family structure is suffering profound changes that directly affect the practices of health care. This study redeem the family concepts and ideas and their social representations and still prove and present the importance and the necessity of the use of these ample instruments of collective boarding in health area: the APGAR, the genogram and eco-map, using the environment observation and family history - crucial factors to the reality of the nuclear family diagnosis - for further planning of health action strategies. It was concluded that the current structure of the family require training from the health teams, for physical, cultural, biological and social points of the family context for the correct use of the instruments cited, important tools for collective approach in the public health area.

Trust and Social Networks in a Changing Europe.

This project set out to investigate the effects of the recent massive social transitions in Eastern Europe on the everyday social lives of the inhabitants of three very different nations: Georgia, Russia and Hungary. It focused in particular on the availability and nature of the support networks available to three different segments of each of the societies (manual workers, students and entrepreneurs) and the impact of network participation on psychological and physical well-being. The group set four specific questions to investigate: the part played by individual psychological beliefs in the formation and maintenance of social networks and the consequent formation of trusting relations; the implication of the size and quality of these networks for mental health; the nature of the social groups inhabited by the respondents and the implication of their work schedule and daily routines on the maintenance of a social and family life; and an analysis of how cultures vary in their social networks and intimacy. Three different methods were used to examine social support and its implications: structured questionnaires, semi-structured short interviews and a media analysis of newspaper materials. The questionnaires were administered to 150 participants in each country, equally divided between students studying full time, manual workers employed in factories, and business people (small kiosk owners, whose work and life style differs considerably from that of the manual workers). The questionnaires investigated various predictors of social support including the locus of control, relationship beliefs, individualism-collectivism and egalitarianism, demographic variables (age, gender and occupation), social support, both in general and in relation to significant events that have occurred since the transition from communism. Those with an internal locus of control were more likely to report a higher level of social support, as were collectivists, while age too was a significant predictor, with younger respondents enjoying higher levels of support, regardless of the measures of support employed. Respondents across the cultures referred to a decline of social support and the group also found a direct correlation between social support and mental health outcomes. All 450 respondents were interviewed on their general responses to changes in their lives since the fall of communism and the effects of their work lives on their social lives and the home environment. The interviews revealed considerable variations in the way in which work-life offered opportunities for a broader social life and also provided a hindrance to the development of fulfilling relationships. Many of the work experiences discussed were culture specific, with work having a particularly negative impact on the social life of Russian entrepreneurs but being seen much more positively in Georgia. This may reflect the nature of support offered in a society as overall support levels were lowest in Russia, meaning that social support may be of particular importance there. The way in cultural values and norms about personal relationships are transmitted in a culture is a critical issue for social psychologists and the group examined newspaper articles in those newspapers read by the respondents in each of the three countries. These revealed a number of different themes. The concept of a divided society and its implications for personal relationships was clearest in Russian and Hungary, where widely-read newspapers dwelt on the contrast between "new Russians/Hungarians" and the older, poorer ones and extended considerable sympathy to those suffering from neglect in institutions. Magyar Nemzet, a paper widely read by Hungarian students reflects the generally more pessimistic tone about personal relationships in Russia and Hungary and gave a particularly detailed analysis of the implications this holds for human relations in a modern society. In Georgia, however, the tone of the newspapers is more positive, stressing greater social cohesion. Part of this cohesion is framed in the context of religion, with the church appealing to a broader egalitarianism, whereas in less egalitarian Hungary appeals by the Church are centred more on the nuclear family and its need for expansion in both size and influence. The division between the sexes was another prominent issue in Hungary and Russia, while the theme of generational conflict also emerged in Hungarian and Georgian papers, although with some understanding of "young people today". The team's original expectation that the different newspapers read by the different groups of respondents would present differing images of personal relationships was not fulfilled, as despite variations in style, they found little clear "ideological targeting" of any particular readership. They conclude that the vast majority of respondents recognised that the social transition from communism has had a significant impact on the well-being of social relationships and that this is a pertinent issue for all segments of society. While the group see the data collected as a source to be worked on for some time in the future, their initial impressions include the following. Social support is clearly an important concern across all three countries. All respondents (including the students) lament the time taken up by their heavy work schedules and value their social networks and family ties in particular. The level of social support differs across the countries investigated, with Georgian apparently enjoying significantly higher levels of social support. The analysis produced an image of a relatively cohesive and egalitarian society in which even the group most often seen as distant from the general population, business people, is supported by a strong social network. In contrast, the support networks available to the Russian respondents seem particularly weak and reflect a general sense of division and alienation within the culture as a whole. The implications of low levels of social support may vary across countries. While Russians reported the lowest level of mental health problems, the link between social support and mental health may be strongest in that country. In contrast, in Hungary it is the link between fatalism and mental health problems which is particularly strong, while in Georgia the strongest correlation was between mental health and marital quality, emphasising the significance of the marital relationship in that country.

Flexibilidad Polivalencia: modelos de libertad para la vivienda social en España

Este trabajo estudia la validez de la flexibilidad y la polivalencia, en tanto que estrategias de diseño doméstico, para superar los problemas derivados de la coincidencia de dos circunstancias opuestas en el campo de la vivienda social. Por un lado, la existencia en España de un rígido conjunto de normativas de diseño, originado a mediados del siglo pasado bajo unos supuestos culturales e ideológicos distintos a los actuales, que fija una idea muy precisa de hogar. Por otro lado, la creciente variedad de modos de habitar derivada del progreso social, económico y tecnológico de las últimas décadas. La tesis presenta dos partes ligadas entre sí. La primera es una investigación bibliográfica en la que se analizan los diferentes conceptos asociados a la flexibilidad y la polivalencia manejados hasta hoy, se estudian las formas en las que estas estrategias se presentan a través de ejemplos, algunos de ellos muy poco conocidos, y se exponen las oportunidades y los obstáculos para su desarrollo en nuestro país. La segunda parte es una investigación experimental que incluye los estudios de evaluación de dos edificios madrileños de referencia, las viviendas flexibles de Aranguren y Gallegos en Carabanchel y las viviendas polivalentes de la Casa de las Flores, de Secundino Zuazo. En ellos se analizan las ventajas y desventajas de los distintos dispositivos flexibles y polivalentes existentes en dichas viviendas; cómo influyen en la organización de la vida doméstica; cuáles de sus características merecen ser implementadas en nuevos proyectos y bajo qué condiciones. La investigación revela que la flexibilidad ofrece ventajas funcionales objetivas, pero que su generalización en nuevas promociones de vivienda ocasionaría problemas de índole cultural. Por otro lado, la polivalencia es eficaz para dar cabida a nuevos modelos de convivencia, pero choca con las preferencias de los grupos familiares tradicionales. En ambos casos, se proponen soluciones para mejorar su eficacia. ABSTRACT The aim of this thesis is to assess the validity of flexibility and polyvalence as architectural responses to address some of the issues derived from two concurrent –yet opposing– circumstances in the field of Spanish social housing. On the one hand, the existence of a thick set of rules that strictly defines the form and use of the domestic space. These design norms were originated in the mid-20th century, according to an institutionalised idea of nuclear family and family home that does not match the current social trends in the country. On the other hand, the growing variety of lifestyles and family groups derived from the social, economic and technological progress of the last decades. The thesis is divided into two interrelated parts: The first one is a bibliographic research and an analysis of the diverse concepts attached to flexibility and polyvalence existing in the literature, a study of the ways in which these strategies are practiced in relevant housing buildings, and an explanation of the benefits and difficulties they pose with respect to their development in Spain. The second part is an experimental research including two post-occupancy evaluations in two housing buildings in Madrid: the flexible apartments in Carabanchel by Aranguren & Gallegos, and the polyvalent apartments in la Casa de las Flores by Secundino Zuazo. These studies are aimed at determining the extent to which the flexible and polyvalent elements in these projects are successful, which users take advantage of them and, over all, which of these features deserve to be applied to future developments, and under which conditions. The research indicates that, despite offering objective functional advantages, flexibility cannot be proposed as a general strategy in future subsidised housing developments due to the cultural problems it provokes. Besides, polyvalence is useful to host new cohabitations models, but it clashes with the preferences of traditional family groups. In both cases, several solutions to improve their efficiency are presented.
