Abstract: species richness, composition, abundance and diversity of birds were analyzed in different environmental units in the pre-delta national park (entre rios, argentina). three environmental units (non-flooded riverine forest, flooded riverine forest and wetlands) were sampled by point counts from march 2006 until march 2007. a total of 147 bird species and an average abundance of 1845 individuals were recorded. a significant difference among habitats was observed in species richness, average abundance and diversity. wetlands showed the highest richness and abundance values. both types of riverine forests exhibited a relatively low number or species, although the flooded riverine forest showed the highest average diversity values. both forests shared most species, and contributed with only 29 species (20%) which did not appear in wetlands, and with 22 indicator species. wetlands, with higher proportions of species number and abundance, constitute the most representative environmental unit. some forest indicator species were also recorded in wetlands because of the closeness between environmental units. the high number of additional species suggests a large amount of generalist species. an integral approach embracing all environmental units is needed in order to understand the dynamics of this avifauna.

Abstract: Hasta el momento no contábamos con estimaciones a nivel nacional de los principales factores de riesgo de morbimortalidad por enfermedades cardiovasculares que permitieran una estrategia de promoción y prevención primaria. En el marco del desarrollo de políticas de salud pública, el Ministerio de Salud de la Nación inició las actividades para la realización de la primera “Encuesta Nacional de Factores de Riesgo”. ObjetivosDescribir la prevalencia de los principales factores de riesgo de enfermedades cardiovasculares en la Argentina y su asociación con características sociodemográficas.Material y métodosDesde el 12 marzo y hasta el 17 de junio de 2005 se llevó a cabo la primera Encuesta Nacional de Factores de Riesgo. Se utilizó un cuestionario validado previamente para la Argentina, propuesto por la OPS y la OMS. La muestra fue probabilística, a nivel de viviendas, con representatividad nacional y provincial. Criterio de inclusión: población adulta (18 a os y más). Se obtuvieron los principales indicadores de prevalencia de acuerdo con las recomendaciones de los CDC, se evaluaron asociaciones entre características sociodemográficas y se estimó la frecuencia de control de presión arterial y colesterol.ResultadosSe realizaron 41.392 encuestas, con una tasa de respuesta del 86,7%. Los principales indicadores a nivel nacional fueron: baja actividad física 46,2%, consumo de tabaco 33,4% 18 a 64 a os y 29,7% en adultos, presión arterial elevada 34,4% (en personas que se controlaron),sobrepeso-obesidad 49,1%, bajo consumo de frutas y verduras 35,3%, diabetes 11,9%(en personas que se controlaron), colesterol elevado 27,8% (en personas que se controlaron),consumo de alcohol de riesgo 9,6%. Para casi todos los factores de riesgo evaluados se observó mayor prevalencia en la población de menores ingresos, con necesidades básicas insatisfechas y menor nivel educativo. Se observaron prevalencias significativas también enprovincias del NEA y el NOA. Control referido de factores de riesgo: de presión arterial en últimos 2 a os 78,7%, de colesterol en mayores de 20 a os 56,8%. Prevalencia de riesgo moderado-alto de eventos cardiovasculares observada: 28,4%.ConclusionesEsta primera Encuesta Nacional de Factores de Riesgo será de utilidad para el desarrollo de políticas públicas de prevención y control de enfermedades cardiovasculares y será labase de un sistema de vigilancia epidemiológica que permita la toma de decisiones en salud pública.
Filosofia e luogo pubblico
Rocco Ronchi
Nóema , 2011,
Abstract: Il luogo della filosofia, almeno per chi frequenta una certa tradizione e un certo strumentario filosofico, è quello genealogico e autobiografico, cioè quello che consiste nel chiedere conto del luogo stesso della filosofia, della sua pratica, della sua verità. Ora, questo cortocircuito, lungi dal configurare una condizione di paralisi, costituisce l'assoluto stesso della pratica filosofica e il fondamento in atto della verità a cui quella pratica dà legittimamente accesso. In questa stessa prospettiva va riaffrontata la questione "fenomenologica" della coscienza e della correlazione coscienza mondo, nonché il suo esito più avanzato, che riguarda, nel lessico della tradizione filosofica di cui si è detto, il problema dell'evento come nodo di relazioni.

Abstract: Secondary analysis of Argentina's 2005 Encuesta Nacional de Factores de Riesgo (National Risk Factor Survey, N = 41,392) using a novel analytical strategy first proposed by the United Nations Development Programme (UNDP), which we here refer to as the Average/Deprivation/Inequality (ADI) framework. The analysis focuses on two risk factors (unhealthy diet and obesity) and one related disease outcome (diabetes), a notable health concern in Latin America. Logistic regression is used to examine the interplay between socioeconomic and demographic factors. The ADI analysis then uses the results from the logistic regression to identify the most deprived, the best-off, and the difference between the two ideal types.Overall, 19.9% of the sample reported being in poor/fair health, 35.3% reported not eating any fruits or vegetables in five days of the week preceding the interview, 14.7% had a BMI of 30 or greater, and 8.5% indicated that a health professional had told them that they have diabetes or high blood pressure. However, significant variation is hidden by these summary measures. Educational attainment displayed the strongest explanatory power throughout the models, followed by household income, with both factors highlighting the social patterning of risk factors and disease outcomes. As educational attainment and household income increase, the probability of poor health, unhealthy diet, obesity, and diabetes decrease. The analyses also point toward important provincial effects and reinforce the notion that both compositional factors (i.e., characteristics of individuals) and contextual factors (i.e., characteristics of places) are important in understanding the social patterning of chronic diseases.The application of the ADI framework enables identification of the regions or groups worst-off for each outcome measure under study. This can be used to highlight the variation embedded within national averages; as such, it encourages a social perspective on population healt

Abstract: lead (pb) is a highly toxic non-essential metal that affects different organs and tissues. although at the present a unique mechanism by which this metal exerts its toxic effects has not been described, a large number of studies have highlighted the fundamental role of oxidative stress in the pathophysiology of pb poisoning. in this regard, it has been reported that pb-induced oxidative stress can occur at different levels: by the generation of ?-aminolevulinic acid (?-ala), through its ability to induce lipid peroxidation in the presence of ferrous ion (fe2+), or via glutathione (gsh) or antioxidant enzyme depletion. on the basis of these antecedents, the aim of this review is to present recent evidence regarding the implication of oxidative stress in the adverse effects caused by pb, to emphasize the possibility to use oxidative stress biomarkers as a complementary method for early detection of pb exposure, and to reveal the importance of antioxidant compounds as novel tools in the prevention and treatment of pb exposure.
