Trends in death from circulatory diseases in Brazil between 1979 and 1996

OBJECTIVE: To analyze the trends in mortality due to circulatory diseases in men and women aged > or = 30 years in Brazil from 1979 to 1996. METHODS: We analyzed population count data obtained from the IBGE Foundation and mortality data obtained from the System of Information on Mortality of the DATASUS of the Ministry of Health. RESULTS: Circulatory diseases, ischemic heart disease, and cerebrovascular disease were the major causes of death in men and women in Brazil. The standardized age coefficient for circulatory disease in men aged > or = 30 years ranged from 620 to 506 deaths/100,000 inhabitants and in women from 483 to 383 deaths/100,000 inhabitants for the years 1979 and 1996, respectively. In men, the mean coefficient for the period was 586.25 deaths with a significant trend towards a decrease (P<0.001) and a decline of 8.25 deaths/year. In women, the mean coefficient for the period was 439.58 deaths, a significant trend towards a decrease (P<0.001) and a rate of decline of 7.53 deaths/year. The same significant trend towards a decrease in death (P<0.001) was observed for ischemic heart disease and cerebrovascular disease. Risk of death from these causes was always higher for men of any age group (P<0.001). Cerebrovascular disease was the primary cause of death in women. CONCLUSION: Although circulatory diseases have been the major cause of mortality in men and women in the Brazilian population, with a greater participation by cerebrovascular diseases, a trend towards a decrease in the risk of death from these causes is being observed.

Trends of the Risk of Death due to Circulatory, Cerebrovascular, and Ischemic Heart Diseases in 11 Brazilian Capitals from 1980 to 1998

OBJECTIVE: To assess the trends of the risk of death due to circulatory (CD), cerebrovascular (CVD), and ischemic heart diseases (IHD) in 11 Brazilian capitals from 1980 to 1998. METHODS: Data on mortality due to CD, CVD and IHD were obtained from the Brazilian Health Ministry, and the population estimates were calculated by interpolation with the Lagrange method based on census data from 1980 and 1991 and the population count of 1996. The trends were analyzed with the multiple linear regression method. RESULTS: CD showed a trend towards a decrease in most capitals, except for Brasília, where a mild increase was observed. The cities of Porto Alegre, Curitiba, Rio de Janeiro, Cuiabá, Goiânia, Belém, and Manaus showed a decrease in the risk of death due to CVD and IHD, while the city of Brasília showed an increase in CVD and IHD. The city of São Paulo showed a mild increase in IHD for individuals of both sexes aged 30 to 39 years and for females aged 40 to 59 years. In the cities of Recife and Salvador, a reduction in CD was observed for all ages and both sexes. In the city of Recife, however, an increase in IHD was observed at younger ages (30 to 49 years), and this trend decreased until a mild reduction (-4%) was observed in males ³ 70 years. CONCLUSION: In general, a reduction in the risk of death due to CD and an increase in IHD were observed, mainly in the cities of Recife and Brasília.

Acute myocardial infarction: clinical and epidemiological profile and factors associated with in-hospital death in the municipality of Rio de Janeiro

OBJECTIVE: To study the factors associated with the risk of in-hospital death in acute myocardial infarction in the Brazilian public health system in Rio de Janeiro, Brazil. METHODS: Sectional study of a sample with 391 randomly drawn medical records of the hospitalizations due to acute myocardial infarction recorded in the hospital information system in 1997. RESULTS: The diagnosis was confirmed in 91.7% of the cases; 61.5% males; age = 60.2 ± 2.4 years; delta time until hospitalization of 11 hours; 25.3% were diabetic; 58.1% were hypertensive; 82.6% were in Killip I class. In-hospital mortality was 20.6%. Thrombolysis was used in 19.5%; acetylsalicylic acid (ASA) 86.5%; beta-blockers 49%; angiotensin-converting enzyme (ACE) inhibitors 63.3%; calcium channel blockers 30.5%. Factors associated with increased death: age (61-80 years: OR=2.5; > 80 years: OR=9.6); Killip class (II: OR=1.9; III: OR=6; IV: OR=26.5); diabetes (OR=2.4); ventricular tachycardia (OR=8.5); ventricular fibrillation (OR=34); recurrent ischemia (OR=2.7). The use of ASA (OR=0.3), beta-blockers (OR=0.3), and ACE inhibitors (OR=0.4) was associated with a reduction in the chance of death. CONCLUSION: General lethality was high and some interventions of confirmed efficacy were underutilizated. The logistic model showed the beneficial effect of beta-blockers, and ACE inhibitors on the risk of in-hospital death.

Mecanismos Celulares y Moleculares que regulan la Secreción, Proliferación y Muerte de Células Lactotropas. Cellular and molecular mechanisms that regulate secretion, proliferation and death of lactotroph cells.

El presente proyecto está dirigido a estudiar los mecanismos celulares y moleculares involucrados en la regulación de la población de lactotropas, como resultado del balance entre los procesos de proliferación y muerte celular correlacionados con la secreción de prolactina. Dentro de las vías de transducción de señales involucradas se determinará la activación de las diferentes isoformas de PKC utilizando inhibidores específicos y la participación de la vía MAPK-ERK1/2 en cultivos primarios adenohipofisarios y en la línea tumoral GH3B6. Además, se completará la caracterización morfológica y bioquímica de los diferentes procesos de muerte celular inducidos por bromocriptina en modelos de regresión de prolactinomas. Se incorporan al presente proyecto nuevas líneas de investigación dirigidas a estudiar la participación de receptores estrogénicos nucleares y de membrana sobre la actividad secretoria y proliferativa de células lactotropas. Se fija como objetivo la identificación de los mismos y su translocación intracelular en respuesta a estímulos específicos. Estas investigaciones se realizarán en cultivo primario de adenohipófisis, a nivel de microscopía electrónica y confocal. La participación de las isoformas alfa y beta de receptores estrogénicos intracelulares y de membrana en los efectos del estradiol sobre la proliferación y secreción de PRL se determinará mediante el uso de agonistas y antagonistas específicos en cultivo primario de adenohipófisis y de la línea GH3B6. Un tema de actualidad es el estudio de vías de señalización involucradas en las acciones del estrógeno en interacción con neuropéptidos o factores de crecimiento, estableciendo la interacción entre los receptores de membrana, además de posibles "crosstalk" entre diferentes rutas de transducción de señales. Como aporte a este tópico se propone estudiar los efectos genómicos y no genómicos del estradiol en interacción con TRH o FGF-2, modulando la actividad secretoria y proliferativa de las células lactotropas. Los datos obtenidos podrán contribuir al conocimiento de nuevas estrategias utilizadas para disminuir el crecimiento de tumores, inhibiendo moléculas claves como receptores de estrógenos, factores de crecimiento y algunas involucradas en las vías de señalización.

Investigación de defectos genéticos en el sistema de la fosforilasa hepática en pacientes argentinos. Definición nosológica mediante una estrategia de análisis molecular. Investigation of genetic defects in the hepatic phosphorylase system in Argentinean patients. Nosological definition by molecular analysis strategy.

Las Enfermedades de Atesoramiento de Glucógeno (EAGs) también llamadas Glucogenosis comprenden un grupo de entidades causadas por una deficiencia enzimática específica relacionada con la vía de síntesis o degradación de esta macromolécula. La heterogeneidad fenotípica de los pacientes afectados dificulta la identificación de las diferentes variantes de EAG y por ende la correcta definición nosológica. En el Centro de Estudio de las Metabolopatías Congénitas, CEMECO, se fueron definiendo los diferentes tipos de Glucogenosis a través de una estrategia multidisciplinaria que integra distintos niveles de investigación clínica y complementaria, laboratorio metabólico especializado, enzimático, histomorfológico y de análisis molecular. Sin embargo, en algunos enfermos, entre los que se encuentran aquellos con defectos en el sistema de la fosforilasa hepática (EAG-VI y EAG-IX), la exacta definición nosológica aún no está resulta. La EAG-VI se refiere a un defecto en la fosforilasa hepática, enzima codificada por el gen PYGL, mientras que la EAG-IX es causada por un defecto genético en una de las subunidades de la fosforilasa b quinasa hepática codicadas por los genes PHKA2, PHKB y PHKG2, respectivamente. El objetivo del presente trabajo es propender a la definición nosológica de pacientes con defectos en el sistema de la fosforilasa mediante una estrategia de análisis molecular investigando los genes PYGL, PHKA2, PHKB y PHKG2. Los pacientes incluidos en este estudio deberán ser compatibles de padecer una EAG-VI o EAG-IX sobre la base de síntomas clínicos y hallazgos bioquímicos. La metodología incluirá la determinación de la enzima fosforilasa b quinasa en glóbulos rojos y dentro del análisis molecular la extracción de DNA genómico a partir de sangre entera para la amplificación por PCR de los exones más las uniones exon/intron de los genes PHKG2 y PYGL y la extracción de RNA total y obtención de cDNA para posterior amplificación de los cDNA PHKA2 y PHKB. Todos los fragmentos amplificados serán sometidos a análisis de secuencia de nucleótidos. Resultados esperados. Este trabajo, primero en Argentina, permitirá establecer las bases moleculares de los defectos del sistema de la fosforilasa hepática (EAG-VI y EAG-IX). El poder lograr este nivel de investigación traerá aparejado, una oferta integrativa en el vasto capítulo de las glucogenosis hepáticas, con extraordinaria significación en la práctica asistencial para el manejo, pronóstico y correspondiente asesoramiento genético. Hepatic glycogen storage diseases (GSDs) are a group of disorders produced by a deficiency in a specific protein involved in the metabolism of glycogen causing different types of GSDs. Phenotypic heterogeneity of affected patients difficult to identify the different GSD variants and therefore the correct definition of the disease. In the “Centro de Estudio de las Metabolopatías Congénitas”, CEMECO, were defined the different GSD types by a protocol which included complex gradual levels of clinical, biochemical, enzymatic and morphological investigation. However, in some patients, like those one with defects in the hepatic phosphorylase system (GSD-VI and GSD-IX) the exact definition of the disease has not yet been resolved. The GSD-VI is produced by a defect in the PYGL gen that encode the liver phosphorylase, while the GSD-IX is caused by a genetic defect in one of the Phosphorylase b kinase subunits, encoded by the PHKA2, PHKB and PHKG2 genes, respectively. The aim of the present study is to define the phosphorylase system defects in argentinian patients through a molecular strategy that involve the investigation of PYGL, PHKA2, PHKB and PHKG2 genes. Patients included in the present study must be compatible with a GSD-VI or GSD-IX on the bases of clinical symptoms and biochemical findings. The phosphorylase b kinase activity will be assay on in blood red cells. The molecular study will include genomic DNA extraction for the amplification of PHKG2 and PYGL genes and the total RNA extraction for amplification of the PHKA2 and PHKB cDNA by PCR. All PCR-amplified fragments will be subjected to direct nucleotide sequencing. This work, first in Argentina, will make possible to establish the molecular basis of the defects on the hepatic phosphorylase system (GSD-VI and GSD IX). To achieve this level of research will entail advance in the study of the hepatic glycogen storage disease, with extraordinary significance in the treatment, prognosis and the genetic counselling.

Estudio de la muerte celular por Apoptosis en el ovario de Columba maculosa y Columbina picui (Aves:Columbidae) durante el Ciclo Reproductivo Anual. Study of cell death by apoptosis in the ovary of Columba maculosa and Columbina picui (Aves: Columbidae) during the reproductive annual cycle.

En este trabajo se analizarán las características estructurales, cuantitativas y el proceso de muerte celular por apoptosis en el ovario de C. maculosa y C.picui con el objetivo de aportar conocimientos básicos a la biología reproductiva de estas aves. Cincuenta hembras adultas de cada especie se capturarán en el Dpto. Río Primero (Pcia. de Cba), R. Argentina, durante el ciclo reproductivo 2011-2012. Las muestras de ovarios se fijaran en Formalina Neutra pH 7.0, procesarán con la técnica de inclusión en parafina y colorearan con Hematoxilina /Eosina y Reacción Nuclear de Feulgen. Cinco muestras serán utilizadas para la determinación de muerte celular por apoptosis con la técnica de TUNEL. Se estudiarán las características morfohistológicas del ovario de C.maculosa y C. picui e identificarán, categorizarán y cuantificarán los folículos atrésicos no bursting (folículos atrésicos previtelogénicos y vcitelogénicos pequeños que conservan la integridad de la pared folicular) y bursting (folículos vitelogénicos mayores de 2 mm que liberar el contenido folicular por ruptura de la pared folicular) durante el ciclo reproductivo anual. Mediante la marcación de ADN fragmentado, se revelará la muerte celular por apoptosis en las células granulosas de los folículos atrésicos. Se compararán las semejanzas y diferencias estructurales y cuantitativas y el proceso de muerte celular en los folículos regresivos entre las dos especies. Los resultados de este trabajo representarán un importante aporte al conocimiento de la atresia folicular como así también a la muerte celular, un proceso estrechamente asociado a la misma, aún poco estudiado en el ovario de las aves. In this work we analyse the structural, quantitative and the process of the cell death by apoptosis in the ovary of Columba maculosa and Columbina picui in order of providing basic knowledge of reproductive biology of these birds. Fifty adult female of each species will be caught in the Río Primero (Pcia. Cba) R.Argentina, during 2011 - 2012. The ovarian samples will be fixed en neutral buffered Formalin (pH 7.0), processed with the technique of inclusion in paraffin and stained with Haematoxylin - Eosin, and nuclear Reaction of Feulgen. Five samples will be used to reveal cell death by apoptosis with the technique of TUNEL. Will be studied the morphohistological characteristics of ovary of both species, and identify, categorize and quantify the atretic follicles over the cycle, the non-bursting (pre-vitellogenic follicles and vitellogenic small < 2 mm, involution an without follicular rupture) and bursting (vitellogenic follicle > 2 mm in the which the yolk falls into the peritoneum due to rupture of with out put of the wall follicular). Will be revealed DNA fragmentation in the granulosa cells of the atretic follicles. Will compared the similaritues and differences in structure and quantitative and the cell death process by apoptosis in the regresive follicles, between the two species. The results of this study represent an important contribution to the knowledge of follicular atresia as well cell death a process closely associated with it and still poorly studied in the ovary of birds.

An investigation of soil quality parameters relating to agricultural reuse and land disposal options for the management of biosolids

Sludge provides valuable nutrients to soil. Application of sludge to land is subject to a number of limitations. Its use as a soil conditioner represents a "beneficial reuse option". Primary and secondary sludge from Dublin city is treated in Ringsend treatment plant where it undergoes thermal drying. This study investigates the feasibility of land application of thermally dried biosolids (TDB) from Ringsend treatment plant.

Bioremediation of diesel contaminated soils : an investigation into the effects of biosurfactant and organic matter amendments

The aim of this study was to investigate the effects of biosurfactants and organic matter amendments on the bioremediation of diesel contaminated soil. Two strains of Pseudomonas aeruginosa with the ability to produce biosurfactant were isolated from a water and soil sample in Co. Sligo. The first strain, Isolate A, produced a biosurfactant which contained four rhamnose containing compounds, when grown in proteose peptone glucose ammonium salts medium with glucose as the carbon source. Two of the components were identified as rhamnolipid 1 and 2 whilst the other two components were unidentified. The second strain, Isolate GO, when grown in similar conditions produced a biosurfactant which contained only rhamnolipid 2. The type of aeration system used had a significant effect on the abiotic removal of diesel from soil. Forced aeration at a rate of 120L 02/kg soil/ hour resulted in the greatest removal. Over a 112 day incubation period this type o f aeration resulted in the removal o f 48% o f total hexane extractable material. In relation to bioremediation of the diesel contaminated sandy soil, amending the soil with two inorganic nutrients, KH2PO4 and NÜ4N03, significantly enhanced the removal of diesel, especially the «- alkanes, when compared to an unamended control. The biosurfactant from Isolate A and a biosurfactant produced by Pseudomonas aeruginosa NCIMB 8628 (a known biosurfactant producer), when applied at a concentration of three times their critical micelle concentration, had a neutral effect on the biodégradation o f diesel contaminated sandy soil, even in the presence o f inorganic nutrients. It was deduced that the main reason for this neutral effect was because they were both readily biodegraded by the indigenous microorganisms. The most significant removal of diesel occurred when the soils were amended with two organic materials plus the inorganic nutrients. Amendment of the diesel contaminated soil with spent brewery grain (SBG) removed significantly more diesel than amendment with dried molassed sugar beet pulp (DMSBP). After a 108 day incubation period, amendment of the diesel contaminated soil with DMSBP plus inorganic nutrients and SBG plus inorganic nutrients resulted in 72 and 89% removal of diesel range organics (DRO), in comparison to 41% removal of DRO in an inorganic nutrient amended control. The first order kinetic model described the degradation of the different diesel components with high correlation and was used to calculate Vi lives. The V2 life, of the total «-alkanes in the diesel was reduced from 40 days in the control to 8.5 and 5.1 days in the presence of DMSBP and SBG, respectively. The V2 life o f the unresolved complex mixture (UCM) in the diesel contaminated soil was also significantly reduced in the presence o f the two organics. DMSBP and SBG addition reduced UCM V2 life to 86 and 43 days, respectively, compared to 153 days in the control. The component of diesel whose removal was enhanced the greatest through the organic material amendments was the isoprenoid, pristane, a compound which until recently was thought to be nonbiodegradable and was used as an inert biomarker in oil degradation studies. The V2 life of pristane was reduced from 533 days in the nutrient amended control to 49.5 and 19.5 days in DMSBP and SBG amended soils. These results indicate that the addition o f the DMSBP and SBG to diesel contaminated soil stimulated diesel biodégradation, probably by enhancing the indigenous diesel degrading microbial population to degrade diesel hydrocarbons, whilst the addition o f biosurfactants had no enhanced effect on the bioremediation process.

Polish immigrants in Ireland's black economy: a phenomenological investigation

The purpose of this thesis is to answer the research question ‗why do some Polish migrants engage in shadow employment in the Republic of Ireland?‘ The individual and group interviews, which were conducted in August 2011 with thirteen Polish migrants, living and working in Ireland, generated the answer to the research question. Interviewees‘ responses were analysed from the point of view of the literature that examines the various factors within the topics of migration and the black economy. The thesis begins with theoretical background information regarding the enlargement of the European Union and the economic situation of Poland and Ireland. Then migration theories are explained and Polish and Irish migration history is presented. Next, the issue of the black economy and shadow employment is developed with a focus on its presence in Poland and Ireland. The following section is dedicated to the research methodology that was adopted to ensure effective collection of the information. The issues of the qualitative and quantitative research, phenomenological approach to the research and interviews as data collection are raised in that section. The last part of the thesis is based on an analysis of the respondents‘ statements. It explores interviewees‘ experience of life and work in Ireland. The main part of that section develops the reasons why do Polish workers engage in shadow employment in the Republic of Ireland. Simultaneously, it provides the answers to the research question of this thesis.

An Investigation into Irish State patronage of the visual arts.

The focus of this research is in ascertaining how and why the Irish state patronises the visual arts. The framework that the state puts in place for the support of the arts influences the creation of art. The initial standpoint from which to evaluate the system is founded on the belief that art is of social good. The second source of belief is in the necessity for an autonomous setting in which it can be created. These two beliefs underpin state patronage of the arts in contemporary society. Therefore they have to be examined carefully in order to see if they hold up. This requires an investigation into the formation of value. This is undertaken by looking into the social development of western society and its influence on the placement of arts value. Establishing how arts value to society is defined provides a means by which to investigate the manner in which the state patronises the visual arts. Two case studies provide the evidence in how the state supports the arts and why it chooses to do so. The Irish Museum of Modem Art is used as an example of the state’s role in the maintenance of the canon of art. The second case study looks at the work being done by Breaking Ground. Breaking Ground is an extensive art project as an element of the regeneration process happening in Ballymun funded by the state. It provides and insight into how the state utilises art in the unification of a social group.

Investigation into the feasibility of a West of Ireland Pumped Storage System

Ireland’s remote position on the tip of Europe ensures that the country is vulnerable to uncertainty of supply. The reliance on conventional sources of electricity has ensured that escalated prices and high carbon emissions have been witnessed whilst opportunities that inherent resources provide, such as the wind, have not been capitalised upon. The intermittent nature of the wind make it difficult to maximise its potential as in many cases the highest wind speeds are highest when demand is low. The West of Ireland’s combination of wind speeds and unique topography makes it suitable for and innovative wind powered pumped storage system, which can essentially regulate the wind generated electricity and integrate further penetration of renewable energy. In addition, its location along the Atlantic Ocean provides further scope for innovation as seawater can be integrated into the system design. The construction of such an unprecedented project in combination with increased interconnectors has the potential to make Ireland a rechargeable battery for Europe. However, such ambitious plans are at the very early stages and are in direct contrast to current events in the Irish energy market. This study focuses on the feasibility of West of Ireland pumped storage systems. Entailed within this is an extensive desk study, a detailed site selection process and a feasibility study of grid connection. To increase opportunities to identify the best possible site, the feasibility study was focused on the Galway and Mayo areas solely.

An investigation into system security requirements and implementation in an Application Service Provider (ASP) environment

Although the ASP model has been around for over a decade, it has not achieved the expected high level of market uptake. This research project examines the past and present state of ASP adoption and identifies security as a primary factor influencing the uptake of the model. The early chapters of this document examine the ASP model and ASP security in particular. Specifically, the literature and technology review chapter analyses ASP literature, security technologies and best practices with respect to system security in general. Based on this investigation, a prototype to illustrate the range and types of technologies that encompass a security framework was developed and is described in detail. The latter chapters of this document evaluate the practical implementation of system security in an ASP environment. Finally, this document outlines the research outputs, including the conclusions drawn and recommendations with respect to system security in an ASP environment. The primary research output is the recommendation that by following best practices with respect to security, an ASP application can provide the same level of security one would expect from any other n-tier client-server application. In addition, a security evaluation matrix, which could be used to evaluate not only the security of ASP applications but the security of any n-tier application, was developed by the author. This thesis shows that perceptions with regard to fears of inadequate security of ASP solutions and solution data are misguided. Finally, based on the research conducted, the author recommends that ASP solutions should be developed and deployed on tried, tested and trusted infrastructure. Existing Application Programming Interfaces (APIs) should be used where possible and security best practices should be adhered to where feasible.
