Saavedra Maria A.L.,Costa Juvenal S. Dias da,Garcias Gilberto,Horta Bernardo L.
Jornal de Pediatria , 2003,
Abstract: OBJETIVOS: estabelecer a incidência de cólica no lactente e seus determinantes. MéTODOS: entre maio e julho de 1999, a equipe de pesquisa visitou, diariamente, as três principais maternidades da cidade de Pelotas, RS, e todas as mulheres, após o parto, foram entrevistadas, e seus filhos acompanhados aos três meses. Definiu-se a crian a com cólica conforme proposto por Wessel. Os possíveis fatores de risco avaliados foram: classe social, escolaridade materna, idade dos pais, tipo e tempo de relacionamento do casal, altera es no relacionamento na gesta o, tipo de parto, história reprodutiva, qualidade do pré-natal, experiência anterior de aborto, natimorto ou recém-nascido prévio doente, sexo e tipo de alimenta o do lactente. Realizou-se o teste do qui-quadrado para compara es entre propor es e análise multivariada através de regress o logística n o condicional. RESULTADOS: conseguiu-se acompanhar 1.086 crian as das 1.195 identificadas. Na visita aos três meses, a incidência de cólica referida pela m e foi de 80,1%. Entretanto, apenas 16,3% tinham apresentado cólica de acordo com os critérios de Wessel. Após a análise multivariada, as associa es que permaneceram no modelo com desfecho de cólica foram: escolaridade materna, cesariana, idade paterna e amamenta o. Mesmo após ajuste para fatores de confus o, as crian as desmamadas tiveram uma chance 1,86 vez maior de ter cólica do que aquelas ainda amamentadas (IC 95% 1,25-2,77). CONCLUS O: a maioria das m es n o reconheceu corretamente a ocorrência de cólica de acordo com os critérios adotados. O aleitamento materno foi o principal fator de prote o contra o desenvolvimento de cólica.

Abstract: laje de santos marine state park has been pointed out as a site of high marine diversity. in spite of its importance to conservation of marine biota no results of investigations about its marine biodiversity have been published. the aim of this work was to characterize the subtidal seaweed flora of this marine park. samplings were performed by scuba diving: a qualitative one that included the subtidal zone down to 26 m depth and other quantitative at two pre-determined depths, 10 and 20 m. among the 129 taxa identified, 5 species were identified for the first time for the s?o paulo state, 3 for the brazilian coast and 1 for the south atlantic ocean. the most abundant algae were sargassum vulgare and turf composed by geniculate coralline and filamentous groups. the frequency of occurrence of taxa revealed that most of species are restricted to frequencies less than 20 % in all samples. the analyses of the subtidal marine benthic algal flora indicate the marine state park of laje de santos as a site of elevated species richness and that its floristic composition is related to a benthic community structure dominated by turf-forming groups and population of s. vulgare.

Abstract: the objective of this study was to estimate the prevalence and determinants of antidepressant use among adults in a city in southern brazil. the cross-sectional study was based on interviews with adults 40 years or older living in the urban area of pelotas, rio grande do sul state, brazil, 2006. the chi-squared test was used for comparisons between proportions. non-conditional logistic regression was used for multivariate analysis, with robust adjustment for variance. a total of 1,327 adults were interviewed, of whom 9.3% had used antidepressants. use of antidepressants was significantly associated with female gender (or: 2.45; 95%ci: 1.50-4.02), higher socioeconomic status (or: 2.07; 95%ci: 1.28-3.34), and unemployment (or: 1.65; 95%ci: 1.06-2.55). the prevalence of antidepressant use was higher than in other studies. identification of individual determinants of use can serve as the basis for strategies to decrease the consumption of antidepressants in these groups.
Teoría filosófica de la historia: rudimentos para el estudio del fenómeno comunicativo
Horta, Julio;
Andamios , 2008,
Abstract: the purpose of this essay is to expose an area of speculation, which is necessary for the social communication investigator's understanding and investigation of phenomena as historical fact. therefore, we attempt to describe a part of german philosophy of history, to explain the usefulness of its language, categories and relationships, as a theoretical tool in the analytical and interpretive of a communications scholar, for the sake of being able to determine the historic process of communication, the latter understood as a manifestation of a culture semiotics.
CONEXIONES ENTRE LAS CONCEPCIONES DE NUESTRA PERSISTENCIA DIACRóNICA Y DE LA TEMPORALIDAD EN AXIOLOGíA
Horta,Oscar;
Revista de filosofía , 2010, DOI: 10.4067/S0718-43602010000100013
Abstract: the relation between the problem of the temporality of value and the problem of our diachronic persistence has virtually not been explored so far. however, the analysis of these questions can shed light on each other in an interesting way this paper argues that an explanation of the connections between the asymmetry of our attitudes towards the future and the past and the question of our diachronic persistence is possible without begging the question in any way.
TEORíA FILOSóFICA DE LA HISTORIA: RUDIMENTOS PARA EL ESTUDIO DEL FENóMENO COMUNICATIVO
Julio Horta
Andamios , 2008,
Abstract: El propósito de este ensayo es mostrar un ámbito especulativo, necesario para el investigador social de la comunicación, para el entendimiento e investigación del fenómeno comunicativo en tanto hecho histórico-cultural. En razón de esto, se intenta describir una parte de Filosofía Alemana de la Historia, para exponer la utilidad de su lenguaje, categorías y relaciones, como instrumento teórico en la actividad analítica e interpretativa del comunicólogo, en aras de poder determinar, de manera general e integradora, el proceso histórico de la comunicación, entendida esta última como manifestación semiótica de una cultura, pueblo, nación...
La argumentación de Singer en Liberación animal: concepciones normativas, interés en vivir y agregacionismo Singer's Argument in Animal Liberation: Normative Views, Interest in Living and Aggregationism
Oscar Horta
Diánoia , 2011,
Abstract: Este artículo examina los presupuestos metodológicos, axiológicos y normativos en los que descansa la que posiblemente sea la obra más conocida de Peter Singer, Liberación animal. Se exploran las tensiones entre la posición normativa, de compromisos mínimos, que se intenta adoptar en esa obra, y las posiciones de Singer acerca del utilitarismo de las preferencias y el argumento de la reemplazabilidad. Se buscará elucidar en particular el modo en el que surgen tales tensiones al abordarse la consideración del agregacionismo y el interés en vivir en relación con el uso de animales no humanos. This paper examines the methodological, axiological and normative assumptions on which Animal Liberation -arguably the most poular work by Peter Singer- rests. It explores the tensions between the normative position this book intends to adopt, which tries to compromise as little as possible with any specific normative theory, and Singer's views on preference utilitarianism and the replaceability argument. In particular, the paper tries to assess the way in which such tensions arise when aggregationism and the question of the interest in living are considered in relation to the use of nonhuman animals.
La desconsideración de los animales no humanos en la bioética
Horta, óscar
Isegoría , 2010,
Abstract: This paper defends two claims. The first is that, despite the extensive use of nonhuman animals in research, this issue has not been really taken seriously in the field of bioethics. This claim is supported by a survey of recent literature in bioethics. The second claim is that this lack of attention is unwarranted. It is commonly assumed that the interests of nonhuman animals are not morally significant, or at least not as significant as those of humans. However, none of the arguments that have been advanced in defense of this view succeeds. Thus, current studies in bioethics display what may be described as a speciesist bias. Moreover, this also means that the very use of nonhuman animals as resources is questionable. Este trabajo defiende dos tesis. En primer lugar, sostiene que, a pesar del amplio uso de animales no humanos en la investigación, esta cuestión no ha sido tomada realmente en serio en el ámbito de la bioética. Esta afirmación es respaldada mediante un rastreo por la literatura reciente. La segunda tesis consiste en que tal desatención no está justificada. Se asume habitualmente que los intereses de los animales no humanos no son moralmente significativos, o al menos que no lo son como los de los seres humanos. Sin embargo, ninguno de los argumentos que defienden esta idea tiene éxito. Los estudios actuales en bioética manifiestan así lo que podemos llamar un prejuicio especista. Más aún, esto conlleva asimismo que el propio uso de animales no humanos como recursos resulta cuestionable.
Caracteriza??o e impacto clínico tardio do no-reflow associado a interven??o coronária percutanea primária vs. eletiva
Campos, Carlos Augusto Homem de Magalh?es;Ribeiro, Henrique;Ribeiro, Expedito E.;Spadaro, Andre G.;Lemos, Pedro A.;Perin, Marco;Marchiori, Gilberto;Horta, Pedro;Kajita, Luiz J.;Martinez, Eulogio;Ramires, José Antonio F.;

Abstract: background: despite major advances in interventional cardiology in recent years, no-reflow is still observed during percutaneous coronary interventions (pci), and is associated to a worse prognosis. the objective of this study was to characterize the clinical, angiographic and procedural profile of patients with no-reflow as well as assessing its late clinical impact. methods: from january 2004 to february 2009, patients undergoing pci at the instituto do cora??o (incor), presenting no-reflow at any time during the intervention, were evaluated. patients were divided into two groups: reperfusion no-reflow (associated to primary pci) and interventional no-reflow (associated to elective pci). the probability of death was estimated by the kaplan-meier method and cox regression was used to identify its predictors. results: one hundred and thirty-two consecutive patients were evaluated, 81 in the reperfusion no-reflow group and 51 in the interventional no-reflow group. procedural success was observed in 83.5% of the overall population (80.2% vs. 90.2%, respectively; p = 0.149). the long-term probability of death was estimated at 38.6%, and was higher in the reperfusion no-reflow group (55.8% vs. 11.1%; p = 0.005). in the multivariate analysis, only female gender [hazard ratio (hr) 2.5, 95% confidence interval (95% ci) 1.225.14; p = 0.027) and chronic obstructive pulmonary disease (hr 9.35, ci 95% 1.45-60.14; p = 0.027) were independent predictors of mortality, whereas the prior use of statin was a protective factor (hr 0.15, 95% ci 0.05-0.48; p = 0.002). conclusions: the no-reflow phenomenon was associated with high procedural failure rates and long-term mortality, especially when associated to primary angioplasty.
