Abstract: El riesgo de leishmaniasis visceral (LV) urbana epidémica se registró por primera vez en la Argentina en el a o 2004, por presencia del vector Lutzomyia longipalpis en la provincia de Formosa, la provincia de Misiones registra casos de LV humana, LV canina y vector en el a o 2006, y la provincia de Corrientes en el verano 2008-2009. En la provincia de Santiago del Estero los casos de LV humana y LV canina en el a o 2008 estuvieron asociados posiblemente a vectores secundarios. Por ello, para conocer la distribución del riesgo en la región del Chaco, entre enero y abril del 2010 se realizó la búsqueda sistemática del vector de LV en 30 localidades de las provincias de Formosa, Chaco y en la ciudad de Reconquista, Santa Fe (224 trampas/noche). Se comprobó la presencia de Lu. longipalpis, por primera vez, en las localidades de Resistencia y Puerto Antequera (Chaco). En Clorinda y Puerto Pilcomayo (Formosa) se obtuvieron las trampas con más ejemplares, 158 y 241 Lu. longipalpis trampa/sitio/noche respectivamente. Los resultados muestran que el vector de la LV urbana epidémica continúa dispersándose en el territorio argentino, habiendo ingresado a la provincia de Chaco. La notificación de casos esporádicos en la región chaque a, transmitidos por vectores secundarios, como Lu. migonei, podría aumentar también debido a la vigilancia intensificada, y a la dispersión del parásito asociada al tránsito de perros infectados, sintomáticos o asintomáticos. The appearance of the vector of visceral leishmaniasis (VL) Lutzomyia longipalpis in the province of Formosa in 2004 was associated with urban epidemic risk for the first time in Argentina. During 2006, vectors, canine and human cases of VL were reported in the province of Misiones, and in summer 2008-2009, in the province of Corrientes. In Santiago del Estero province in 2008, cases of human and canine VL were associated with secondary vectors. Therefore, with the aim to know the current distribution of VL risk in the Chaco region, systematic captures of the vector were performed between January and April 2010 in 30 localities of Formosa and Chaco, and in the city of Reconquista, province of Santa Fe (224 traps/night). Lu. longipalpis was reported for the first time in the cities of Resistencia and Puerto Antequera (Chaco). Clorinda and Puerto Pilcomayo (Formosa) are the localities where the traps with more individuals were obtained, 158 and 241 Lu. longipalpis trap / site / night respectively. These results showed that the vector of urban epidemic VL is still spreading in Argentina, and already reached the provin

Abstract: the appearance of the vector of visceral leishmaniasis (vl) lutzomyia longipalpis in the province of formosa in 2004 was associated with urban epidemic risk for the first time in argentina. during 2006, vectors, canine and human cases of vl were reported in the province of misiones, and in summer 2008-2009, in the province of corrientes. in santiago del estero province in 2008, cases of human and canine vl were associated with secondary vectors. therefore, with the aim to know the current distribution of vl risk in the chaco region, systematic captures of the vector were performed between january and april 2010 in 30 localities of formosa and chaco, and in the city of reconquista, province of santa fe (224 traps/night). lu. longipalpis was reported for the first time in the cities of resistencia and puerto antequera (chaco). clorinda and puerto pilcomayo (formosa) are the localities where the traps with more individuals were obtained, 158 and 241 lu. longipalpis trap / site / night respectively. these results showed that the vector of urban epidemic vl is still spreading in argentina, and already reached the province of chaco. sporadic cases reported in the chaco region, transmitted by secondary vectors as lu. migonei would also increase due to intensified surveillance, and the dispersion of the parasite associated with the transit of asymptomatic or symptomatic infected dogs.

Abstract: this paper studies the ?mestizo? group of acatzingo (puebla, nueva espa?a) at the end of the xviiith century. placed in the crossroads that connected mexico city, veracruz and tierras calientes, textil manufactures were an important production of the town. determining those features who ?mestizos? shared or not with the other non indigenous groups (spatial distribution, sex, legal status and occupation), permit us to make progress on the knowledge of the influence that ethnic structure have had in the social relationships in nueva espa?a.

La flora arvense en huertos de naranjo ‘valencia’ y su relación con las características del suelo en dos municipios del estado Yaracuy, Venezuela Weed populations in ‘Valencia’ orange groves and their relationship with soil characteristics in two municipalities of Yaracuy State, Venezuela

Abstract: Se caracterizó la flora arvense en el cultivo del naranjo ‘Valencia’ en los municipios Bolívar y Manuel Monje del estado Yaracuy, mediante muestreos de malezas en 236 fincas donde se colectó un total de 506 muestras de 0,5 m2 cada una. Se determinaron los parámetros poblacionales de las malezas, la cobertura del suelo y el índice de valor de importancia (IVI) de cada especie. Se dispuso de la información referente a las características del suelo y contenido mineral foliar del cultivo y se realizó una regresión binaria entre la presencia o no de las especies y los parámetros de suelo, así como correlaciones entre la densidad y cobertura del suelo de las malezas más importantes con los parámetros del suelo y cultivo. Se reportaron 103 especies pertenecientes a 25 familias botánicas, con 23 especies representando el 80 % del IVI total. La densidad y cobertura del suelo por malezas fueron de 44,06 plantas·m-2 y 61,8 % respectivamente, y las cinco especies más importantes fueron Cyperus rotundus, Panicum maximun, Cynodon dactylon, Waltheria americana e Ipomoea tiliacea. Se detectó un número bajo de regresiones y correlaciones significativas lo que indica que los factores del suelo estudiados no serían los más determinantes para definir la tendencia de las variables poblacionales de las malezas, pero sugieren relaciones interesantes que pueden posteriormente ser estudiadas de forma más particular. Weed flora in ‘Valencia’ orange groves in Bolivar and Manuel Monje municipalities of Yaracuy State, Venezuela, was characterized. A total of 506 weed samples (0.5 m2 each) coming from 236 citrus farms were evaluated. Weed population parameters, weed ground cover, and importance value index (IVI) of each species were determined. The soil and leaf mineral contents were available and a binary regression was performed between the presence or absence of weed species and soil parameters, as well as correlations between density and ground cover of most important weeds with parameters of soil and crop plants. It was found 103 species belonging to 25 botanical families, with 23 species representing 80% of the total IVI. The density and weed ground cover were 44.06 plants·m-2 and 61.8% respectively. The five most important species were Cyperus rotundus, Panicum maximum, Cynodon dactylon, Waltheria americana, and Ipomoea tiliacea. A low number of significant correlation and regressions were detected, indicating that the evaluated soil characteristics would not be the most important to define the trend of weed population variables, but suggest interesting relationships that can
Unintended pregnancy in the amazon basin of Ecuador: a multilevel analysis

Abstract: Women aged 15-44 were selected through an ongoing community-based cross-sectional survey conducted in the Orellana province between May and December 2006. Data were fitted using multilevel logistic regression, adjusting for both individual-level and community-level factors as fixed effects and allowing for heterogeneity between communities.The overall prevalence of unintended pregnancy was 62.7%. Two-thirds (73.7%) of indigenous women reported having had at least one unintended pregnancy. Being young, single, and indigenous were significant risk factors for unintended pregnancy, alongside having low access to education and having more than two children. No relationship was found between socioeconomic status and the use of contraceptives. All the variation between communities was explained by individual-level factors.This study showed the significance of individual factors in increasing the risk of unintended pregnancy, while the role of community factors was found to be negligible. In order for all women to be able to realize their right to reproductive autonomy, there needs to be a diverse range of solutions, with particular attention paid to cultural issues.It has been estimated that each year 80 million women in the world experience unintended pregnancy. Unintended pregnancy (both unwanted and mistimed) increases the risk of abortion-related morbidity and mortality [1]; this is especially significant in countries where abortion remains illegal, which is the case in most Latin American countries [2]. Latin America and the Caribbean show the highest incidence rate of unsafe abortion worldwide with 32 unsafe abortions per 100 live births and an estimated 3,700,000 unsafe procedures carried out each year [3]. Unintended pregnancy is also associated with negative impacts on antenatal care, breastfeeding, child nutrition, and infant mortality. The effects on the mother's health have not been researched in any depth, but the existing studies show an increased risk of de
El planteamiento y el análisis del desarrollo de la prospección: dos capítulos olvidados en los trabajos de arqueología territorial
San Miguel Mate, Luis Carlos
Trabajos de Prehistoria , 1992,
Abstract: Althoug studies based on survey have increased or improved, and at the same time there have been good efforts to design a working plan for projects of Territorial Archaeology, in most of these studies, a discussion of the survey plan and the analysis of this plan have been omitted. For this reason, our purpose in this paper is to draw attention to this lack and propose a series of suggestions for the analysis of surveys: number of runs, time of day, circumstances and chronology of discoveries, experience, productivity and the results obtained in different topographic and ecological areas. Pese a la multiplicación y mejora de los estudios basados en la prospección y los notables intentos por dise ar un esquema de trabajo para los proyectos de Arqueología Territorial , se echa en falta en la generalidad de los trabajos un verdadero apartado en el que se recoja el planteamiento de la prospección y se realice un análisis de su desarrollo. Nuestro objetivo en este artículo es precisamente llamar la atención sobre esta carencia y proponer una serie de parámetros para el análisis de la prospección: número de recorridos, horario de localización, circunstancias y cronología de los hallazgos, el factor experiencia, la productividad y los resultados obtenidos en las diferentes áreas topográfico-ecológicas.
