Background: Aortic aneurysm and dissection are important causes of death in older people. Ruptured aneurysms show catastrophic fatality rates reaching near 80%. Few population-based mortality studies have been published in the world and none in Brazil. The objective of the present study was to use multiple-cause-of-death methodology in the analysis of mortality trends related to aortic aneurysm and dissection in the state of Sao Paulo, between 1985 and 2009. Methods: We analyzed mortality data from the Sao Paulo State Data Analysis System, selecting all death certificates on which aortic aneurysm and dissection were listed as a cause-of-death. The variables sex, age, season of the year, and underlying, associated or total mentions of causes of death were studied using standardized mortality rates, proportions and historical trends. Statistical analyses were performed by chi-square goodness-of-fit and H Kruskal-Wallis tests, and variance analysis. The joinpoint regression model was used to evaluate changes in age-standardized rates trends. A p value less than 0.05 was regarded as significant. Results: Over a 25-year period, there were 42,615 deaths related to aortic aneurysm and dissection, of which 36,088 (84.7%) were identified as underlying cause and 6,527 (15.3%) as an associated cause-of-death. Dissection and ruptured aneurysms were considered as an underlying cause of death in 93% of the deaths. For the entire period, a significant increased trend of age-standardized death rates was observed in men and women, while certain non-significant decreases occurred from 1996/2004 until 2009. Abdominal aortic aneurysms and aortic dissections prevailed among men and aortic dissections and aortic aneurysms of unspecified site among women. In 1985 and 2009 death rates ratios of men to women were respectively 2.86 and 2.19, corresponding to a difference decrease between rates of 23.4%. For aortic dissection, ruptured and non-ruptured aneurysms, the overall mean ages at death were, respectively, 63.2, 68.4 and 71.6 years; while, as the underlying cause, the main associated causes of death were as follows: hemorrhages (in 43.8%/40.5%/13.9%); hypertensive diseases (in 49.2%/22.43%/24.5%) and atherosclerosis (in 14.8%/25.5%/15.3%); and, as associated causes, their principal overall underlying causes of death were diseases of the circulatory (55.7%), and respiratory (13.8%) systems and neoplasms (7.8%). A significant seasonal variation, with highest frequency in winter, occurred in deaths identified as underlying cause for aortic dissection, ruptured and non-ruptured aneurysms. Conclusions: This study introduces the methodology of multiple-causes-of-death to enhance epidemiologic knowledge of aortic aneurysm and dissection in Sao Paulo, Brazil. The results presented confer light to the importance of mortality statistics and the need for epidemiologic studies to understand unique trends in our own population.

A quantitative study of late Cenozoic silicoflagellates from the northwestern Pacific sites of Deep Sea Drilling Project Leg 86 shows a relative paleotemperature (Ts) gradient with lowest values (Ts = 30) in the north. Some new ecostratigraphic relations for the region are indicated, such as the last common occurrence of Dictyocha brevispina at 2.6 - 3.0 m.y. ago during a cool interval. Elements of North Pacific and low-latitude biostratigraphic zonations can be identified, but the mixing of cool- and warm-indicator taxa prompted the definition of the new Miocene Mesocena hexalitha Subzone and Pliocene Distephanus jimlingii Subzone. Scanning-electron microscope study of Leg 86 silicoflagellates was done to determine whether various types of skeletal surface texture are temperature dependent. To conduct the study we organized a new surface-texture descriptive code, which characterizes the apical structure/basal ring/spine sequence using new definitions of the terms crenulate (C), linear (L), nodular (N), reticulate (R), and smooth (S). One new silicoflagellate genus, Caryocha Bukry et Monechi, n. gen., is described and several new combinations are made.

The upper sections of Deep Sea Drilling Project Sites 576 (32°21.4'N, 164°16.5'E) and 578 (33°55.6'N, 151°37.7'E) both have stable detrital remanence that can be correlated with the standard reversal stratigraphy. Site 576 contains all reversals above the base of the Gilbert Epoch (5 m.y.) at about 25 m, whereas Site 578 contains a remarkable section of about 60 reversals extending to Anomaly 5B (15 m.y.) at about 150 m sub-bottom depth. In both cases, the paleomagnetic stratigraphy breaks down when accumulation rates drop below 2 m/m.y. At both sites, authigenic manganiferous clays deposited from 70 to 16 m.y. ago accumulated at about 0.4 m/m.y. Similarly, at both sites, the Pleistocene pulse of eolian debris increased accumulation rates by about 6 m/m.y.**2. From 16 to 2 m.y. ago, however, sediment accumulated at Site 578 about five times as rapidly as at Site 576, apparently because of augmented input to the western site by bottom currents.

Esta tesis explora los aportes de la novela histórica uruguaya a los debates abiertos en la posdictadura uruguaya considerando las peculiaridades que este subgénero imprime a sus propuestas, el ángulo nuevo que ofrece. En primer lugar quiero destacar el reclamo -que la novela histórica hace visible- de una relectura y reescritura global de la historia uruguaya desde su "origen" en las guerras de Independencia. Este gesto señala un profundo quiebre en los ideales e imaginarios con los cuales los uruguayos se identificaban y pone en evidencia una aguda desconfianza en las narraciones heredadas sobre la nación. En este sentido la experiencia de la dictadura constituyó una fractura que impulsó el cuestionamiento de sus relatos consolidados y su necesaria reescritura bajo diferentes presupuestos. En el prefijo "post" de posdictadura es posible advertir no sólo una dimensión temporal sino un giro epistémico que reorganiza los dispositivos identitarios, los imaginarios comunitarios y los relatos nacionales desde otro locus de enunciación. Este cambio de paradigma lo expone de un modo notable la novela histórica en tanto cuestiona el "origen" de la nación y con ello los andamios que sostenían el entero edificio. En segundo lugar, el conjunto de novelas históricas de estos años lee el pasado desde la nueva agenda del presente. Cuestiones como la memoria, la justicia, la tolerancia, las identidades excluidas, los autoritarismos se discuten desde la peculiar perspectiva de la novela histórica que los desplaza hacia el pasado. La reescritura del pasado, como sabemos, se constituye -y ahora de un modo notable- desde las preocupaciones del presente. Este se convierte en un foco que ilumina zonas en penumbras del pasado, desentierra historias semiolvidadas, escarba en archivos particulares y oficiales, pone en escena problemáticas ausentes. Desde la lente de la experiencia de la última dictadura, la ficción diseña, por un lado, una "cartografía de la barbarie" que -descolocando la teleología del progreso- vincula procesos autoritarios de diversa índole; por el otro trama una red simbólica, un "imaginario de las dictaduras"
