Širší souvislosti dopadu sluneční aktivity na úmrtnost podle příčin v České republice / The wider context of the impact of solar activity on mortality by cause in the Czech Republic

Podolská, Kateřina January 2018 (has links)
The wider context of the impact of solar activity on mortality by cause in the Czech Republic Abstract The presented dissertation investigates the influence of extraterestrial phenomena, in the whole scope of their possible effects, on human population. It analyses the influence of climate-change induced fluctuation of solar activity on the population, as well as the impact of the concentration of cosmogenic radionuclides on human health. In the introduction, the manifestation of solar activity on Earth is described, the results of the present research is summarized, and the used methods of data processing and the data sources are described. The primary focus of this work is the association of mortality from the causes of death recorded under chapter IV. Diseases of the nervous system and chapter IX. Diseases of the circulatory system of the International Classification of Diseases, 10th revision (ICD-10) in the Czech Republic with the changes in the level of solar activity and its exceptional fluctuations. The main aim is to determine the possible link between the daily numbers of dead by the respective causes of death, by sex and age groups in the Czech Republic, on global as well as on geographically specific daily values of solar, ionospheric, and geomagnetic parameters in the years 1994-2013. These are...

Causas múltiplas de morte: formas de apresentação e métodos de análise / Multiple causes of death: presentation forms and methods of analysis

Santo, Augusto Hasiak 17 March 1989 (has links)
RESUMO As informações sobre a mortalidade são tradicionalmente uma importante fonte de dados para estudos epidemiológicos, demográficos e para o planejamento em saúde. As estatísticas de mortalidade por causa são usualmente apresentadas segundo a causa básica de morte; a cada óbito corresponde uma só causa. Este método tem sofrido criticas devido a algumas de suas limitações, principalmente em relação às doenças crônicas quando, geralmente, estão presentes várias causas no momento da morte e apenas a básica é selecionada. As estatísticas de mortalidade segundo as causas múltiplas de morte se apresentam como um método alternativo para o estudo das causas de morte. A introdução dos computadores permitiu o desenvolvimento nos Estados Unidos de um sistema automático para classificar além da causa básica todos os demais diagnósticos mencionados nos atestados de óbito. Esse sistema, denominado ACME (Automated Classification of Medical Entities) amplia muito as possibilidades do uso das estatísticas de mortalidade e desde 1983 vem sendo utilizado no processamento de dados sobre os óbitos ocorridos no Estado de São Paulo. O presente trabalho discute a potencialidade do uso das causas múltiplas de morte para o estudo da mortalidade e apresenta algumas formas para a tabulação e a análise destas estatísticas exemplificadas com o arquivo de dados sobre os óbitos ocorridos em 1983 no Estado de São Paulo. Por meio da análise do número de diagnósticos informados na declaração de óbito mostrou-se um número médio maior dos mesmos em relação aos achados em trabalhos acadêmicos realizados com óbitos de períodos anteriores. 0 estudo das menções de todos os diagnósticos permitiu evidenciar a importância relativa maior de certas causas selecionadas como causa básica menos frequentemente. A análise das associações das causas de morte mostrou a importância do inter-relacionamento das doenças na determinação de morte e sugeriu outros usos das causas múltiplas. A distribuição conjunta das causas externas de morte com os dados sobre a natureza da lesão e a análise desta última segundo o sexo e a idade apresentam-se como nova perspectiva para a compreensão das mortes violentas. O levantamento e a discussão de questões metodológicas sugerem novas áreas de investigação para o estudo das causas múltiplas de morte / SUMMARY Informations about mortality are traditionally an important source of data for epidemiologic and demographic studies as well as for health planning. Mortality statistics based on causes have been derived from the underlying cause of death, implying that for each dead person only one cause is presented. These statistics have been criticised on account of their limitations, mainly when chronic diseases are considered and several causes are responsible for the death. Multiple cause mortality statistics represent an alternative method for the study of causes of death. The advent of computers made possible, in the United States, the development of an automated system for selecting the underlying cause of death as well as for coding all the reported conditions on the death certificate. This system, called ACME (Automated Classification of Medical Entities), greatly enlarges the possibilities of mortality statistics and it is used since 1983 to produce mortality data in the State of São Paulo. This thesis discusses the potential use of multiple cause of death for mortality studies and present some ways of its tabulations and analysis through examples which use the data file of death that occurred in 1983 in the State of São Paulo. The tabulation of the number of different diagnoses reported on the death certificate showed that its median number has increased when compared with the results of academic studies undertaken in other periods of time. The study of all mentions of the reported diagnoses depicted the greater importance of some causes of death infrequently selected as the underlying cause of death. The analysis of associations of causes of death revealed the importance of the combination of diseases to the determination of the death and allowed suggestions for other applications of multiple cause data. The cross tabulation of external causes of death with data related to the nature of injury and the analysis of the nature of injury by age and sex enhance new perspectives for the description and understanding of violent deaths. Methodological questions raised and discussed in this thesis suggest new areas of investigation for the study of multiple causes of death

Redistribution of heart failure as the cause of death: the Atherosclerosis Risk in Communities Study

Snyder, Michelle, Love, Shelly-Ann, Sorlie, Paul, Rosamond, Wayne, Antini, Carmen, Metcalf, Patricia, Hardy, Shakia, Suchindran, Chirayath, Shahar, Eyal, Heiss, Gerardo January 2014 (has links)
BACKGROUND:Heart failure is sometimes incorrectly listed as the underlying cause of death (UCD) on death certificates, thus compromising the accuracy and comparability of mortality statistics. Statistical redistribution of the UCD has been used to examine the effect of misclassification of the UCD attributed to heart failure, but sex- and race-specific redistribution of deaths on coronary heart disease (CHD) mortality in the United States has not been examined.METHODS:We used coarsened exact matching to infer the UCD of vital records with heart failure as the UCD from 1999 to 2010 for decedents 55years old and older from states encompassing regions under surveillance by the Atherosclerosis Risk in Communities (ARIC) Study (Maryland, Minnesota, Mississippi, and North Carolina). Records with heart failure as the UCD were matched on decedent characteristics (five-year age groups, sex, race, education, year of death, and state) to records with heart failure listed among the multiple causes of death. Each heart failure death was then redistributed to plausible UCDs proportional to the frequency among matched records.RESULTS:After redistribution the proportion of deaths increased for CHD, chronic obstructive pulmonary disease, diabetes, hypertensive heart disease, and cardiomyopathy, P<0.001. The percent increase in CHD mortality after redistribution was the highest in Mississippi (12%) and lowest in Maryland (1.6%), with variations by year, race, and sex. Redistribution proportions for CHD were similar to CHD death classification by a panel of expert reviewers in the ARIC study.CONCLUSIONS:Redistribution of ill-defined UCD would improve the accuracy and comparability of mortality statistics used to allocate public health resources and monitor mortality trends.

Epidemiological Studies of Small Intestinal Tumours

Zar, Niklas January 2008 (has links)
<p>Malignant tumours of the small intestine are rare. Age-standardised incidence in Europe is between 0.5-1.5 per 100 000. As the small intestine represents more than 90 % of the gastrointestinal mucosal surface, it is surprising that it gives rise to less than 2 % of gastrointestinal malignancies. The dominating histological subtypes are carcinoids and adenocarcinomas. </p><p>We used three population-based registries in Sweden to study survival, second malignant tumours, causes of death, and Crohn’s disease as a risk factor for small intestinal adenocarcinoma and carcinoid.</p><p>We evaluated tumour site, sex, age, and year of diagnosis as prognostic factors. For adenocarcinomas there was no difference in survival between duodenal and jejunal/ileal tumours. Women with jejunal/ileal adenocarcinomas showed higher probabilities of survival than men, while no such relation was found for duodenal tumours. Old age correlated with poor survival for duodenal tumours, and prognosis has improved in later years. For carcinoids, duodenal tumours had a more favourable prognosis than jejunal/ileal tumours. There was no difference in survival between sexes. Old age correlated with poor survival, and survival has improved in recent years.</p><p>Female patients with adenocarcinoma had increased risk of acquiring cancer in the genital organs and breasts, and both sexes had increased risks of second tumours in the gastrointestinal tract and skin. Men with carcinoid tumours had increased risk of prostate cancer. Both sexes had increased risk of malignant melanoma and malignancies of endocrine organs.</p><p>Patients with adenocarcinoma had increased risk of dying from malignant diseases other than the primary small intestinal cancer and from gastrointestinal disease. The cohort with carcinoid had higher than expected risk of dying from malignant disease, gastrointestinal disease, and cardiovascular disease.</p><p>Patients with Crohn’s disease had increased risk of small intestinal adenocarcinoma and carcinoid, and the risk has increased for patients diagnosed in recent years.</p>

Vliv změny parametrů termálního plazmatu Země a slunečních indexů na úmrtnost podle příčin v České republice / Impact of changes in Earth thermal plasma parameters and solar indices on mortality by cause in the Czech Republic

Podolská, Kateřina January 2013 (has links)
The aim of this diploma thesis was to study the dependence of the intensity of mortality in the Czech Republic, according to the chosen causes of death, on the Solar activity during the increasing and decreasing phase of the Solar cycle in the period 1994-2011, using the methods of the multivariate statistical analysis. The Solar activity was represented by the indices R, Kp, F10.7 and Dst, and also by the height of the F2 layer and TEC for the Czech Republic. The typology of time profiles for causes of death was identified with the help of cluster analysis using time. The dependence between the analyzed time series was investigated using the multivariate statistical analysis. The correlation of the intensity of mortality from coronary heart disease, from stroke, Edwards' and Pataus' syndrom with the Solar activity parameters was discovered, as well as a stronger dependence on the ionosphere parametres related to the Czech Republic area.

Estudo prospectivo das causas de morte de Falconiformes e Strigiformes de vida livre no município de São Paulo / Prospective study of the causes of death of free-living Falconiformes and Strigiformes at São Paulo City

Joppert, Adriana Marques 09 April 2007 (has links)
O presente trabalho teve como objetivo identificar e caracterizar as causas de morte de aves de rapina de vida livre da região do município de São Paulo e áreas vizinhas. O estudo incluiu 114 aves de rapina, sendo 40 da ordem Falconiformes e 74 da ordem Strigiformes, atendidas pela Divisão de Fauna do município de São Paulo, São Paulo, Brasil, durante o período de outubro de 2002 a maio de 2006. As causas de morte identificadas foram: eutanásia (41,2%); causas não-infecciosas (32,5%); causas infecciosas (19,3%); causas parasitárias (3,5%) e causas indeterminadas (3,5%). As lesões traumáticas osteoarticulares foram o motivo mais freqüente de eutanásia (51,1%), seguindo-se das lesões em tecidos moles (17,0%), lesões isquêmicas das extremidades das asas (17,0%), tricomoníase (10,6%) e causas variadas (4,3%). Os traumas se destacaram como uma importante causa de morte natural ou induzida (eutanásia). Dentre as causas de morte infecciosas, as infecções por protozoários (tricomoníase) (54,5%) foram as mais freqüentes, seguindo-se das infecções bacterianas (40,9%). O presente trabalho permitiu identificar os principais processos que causam a morte de aves de rapina, Falconiformes e Strigiformes na região de São Paulo, fornecendo importantes subsídios para o atendimento clínico e tratamento das condições mais comumente encontradas nessa população. / The goal of this work was to identify and characterize the causes of death of free-living birds of prey from São Paulo city and its surroundings. In the present work 114 raptors were studied, 40 of them belonging to the Falconiformes order and 74 to the Strigiformes order, all admitted at the São Paulo City Fauna Division, Brazil, during the period of October 2002 to May 2006. The causes of death were determined as: euthanasia (41,2%), non-infectious causes (32,5%), infectious causes (19,3%), parasitic diseases (3,5%) and indeterminate (3,5%). Bones and joints lesions were the most frequent cause that lead to euthanasia (51,1%), followed by soft tissue lesions (17%), wing tips ischemic lesions (17%), Trichomoniasis (10,6%) and various causes (4,3%). Trauma outstands as an important cause of natural or induced death, while in the field of infectious diseases trichomoniasis (54,5%) was the most frequent, followed by bacterial infections (40,9%). The present study allowed us to identify the principal processes that cause the death of raptorial birds at São Paulo City. These findings also provided important information for clinical attendance and medical treatment for the most common conditions in this population.

Achados anatomo e histopatológicos de tartarugas verdes juvenis (Chelonia mydas) provenientes do litoral sudeste brasileiro / Anatomopathological and histopathological findings of juvenile green turtles (Chelonia mydas) from the Brazilian southeast coast

Ochoa, Pablo Felipe Cruz 03 April 2017 (has links)
O litoral brasileiro apresenta a ocorrência de cinco das sete espécies de tartarugas marinhas presentes no mundo. A região da costa sudeste brasileira é uma área de alimentação de tartarugas verdes juvenis. Muitas ameaças; a grande maioria delas por ação antrópica estão diminuindo as populações de tartarugas marinhas, mas também causas naturais podem estar envolvidas. O presente trabalho tem por objetivo descrever os principais achados necroscópicos e histopatológicos de tartarugas verdes achadas mortas, ou que morreram no centro de reabilitação do Projeto Tamar na cidade de Ubatuba/SP. Como resultados, relações estatísticas foram encontradas entre achados macroscópicos e formas de captura, além de observar grande quantidade de animais acometidos pela presença de parasitas da família Spirorchiidae e suas lesões. Além disso, foi constatada a evidência de resíduos antropogênicos relacionados a presença de fezes compactas associadas a constipações ou obliterações no trato gastrointestinal. Algumas lesões sugestivas de infeções por agentes bacterianos também foram observadas, mas em menor proporção. Foi realizada a dosagem da concentração de cálcio e magnésio no líquido pericárdico, demonstrando maior concentração destes eletrólitos em animais achados mortos - presos em rede de pesca. Os resultados obtidos neste estudo podem representar uma ajuda para o clínico e determinar a presença de possíveis doenças emergentes nestas populações. / Five of the seven sea turtle species in the world gather into Brazilian coastline. The region of the southeast Brazilian coast is a feeding area for young green turtles. There are many threats, the vast majority of them are decreasing populations of sea turtles by anthropic action, but natural causes may also be involved. The present work had as purpose to describe the main necroscopic and histopathological findings in green turtles that were found dead or that were found dead at the rehabilitation center of Tamar Project in Ubatuba City/SP. As results, statistical relationships were found among macroscopic findings and catching methods, beside the observation of high quantity of animals stricken by the presence of Spirorchiidae family parasites and their lesions. In addition, the evidence of anthropogenic residues related to the presence of compact feces associated with constipation or gastrointestinal obliterations was verified. Some lesions suggests infections by bacterial agents were also observed, but in a small proportion. The dosage of calcium and magnesium in the pericardial fluid was determined, evidencing a higher concentration of these electrolytes in animals found dead trapped in fishing net. The results obtained in this study may represent a support for clinicians and it may determine the presence of possible emerging diseases in these populations.

Estudo de mortalidade de mulheres em idade reprodutiva no município de Ribeirão Preto, Estado de São Paulo, Brasil / Study of women mortality in reproductive age in Ribeirao Preto, State of Sao Paulo, Brazil

Gil, Mariana Marcos 28 September 2012 (has links)
Os óbitos de mulheres em idade reprodutiva correspondem a 16% do total de óbitos femininos em todo o Brasil, indicando a dificuldade dos serviços de saúde em implementar ações baseadas na atenção integral à saúde da mulher no Sistema Único de Saúde, sob o enfoque ampliado da assistência, incorporando a perspectiva de gênero. Objetivo: analisar óbitos de mulheres em idade reprodutiva, residentes em Ribeirão Preto-SP, no período de 2007 a 2009, com ênfase nas causas de morte. Método: foram analisadas 532 Declarações de Óbito (DO) de mulheres de 10 a 49 anos residentes no município de Ribeirão Preto/SP que foram a óbito no período de 2007 a 2009, obtidas por meio do Comitê Municipal de Prevenção da Mortalidade Materna para transcrição integral dos dados. As mortes foram classificadas em maternas declaradas, não maternas e presumíveis. Procedeu-se com a análise dos dados com o software STATA, codificação das causas de acordo com a CID 10 e seleção da causa básica de óbito. Resultados: Os principais grupos de causas de morte foram: neoplasias 137 (26%), doenças do aparelho circulatório 94 (18%), doenças infecciosas e parasitárias 67 (13%) e causas externas 65 (12%). As mortes por causas maternas representaram a antepenúltima causa de óbito. Foram identificadas, após análise dos campos preenchidos na DO, 467 (88%) mortes não maternas, 5 (1%) mortes maternas declaradas e 60 (11%) mortes maternas presumíveis. Conclusão: O padrão de mortalidade do município é semelhante ao do país, apontando a necessidade de incrementar ações nas três esferas de governo voltadas para a saúde da população feminina. Conhecer o perfil de mortalidade de mulheres em idade reprodutiva possibilita a compreensão de suas principais demandas e problemas de saúde oferecendo subsídios para o planejamento de ações focadas em reduzir mortes por causas evitáveis. / The deaths of women in reproductive age represent 16% of all female deaths in Brazil, indicating the difficulty of health services to implement actions based on comprehensive health care of women in the National Health System, under the approach extended care, incorporating a gender perspective. Objective: To analyze deaths of women in reproductive age residing in Ribeirao Preto-SP, in the period of 2007 to 2009, focusing on causes of death. Method: We analyzed 532 Death Certificates of women aged 10 to 49 years residing in Ribeirao Preto - SP who died in the period 2007 to 2009, obtained through the Municipal Committee for the Prevention of Maternal Mortality for transcription full of data. The deaths were classified as declared maternal, not maternal and presumed. Proceeded with the analysis of the data with STATA software, coding causes according to ICD 10 and selecting the underlying cause of death. Results: The main groups of causes of death were neoplasms 137 (26%), circulatory diseases 94 (18%), infectious and parasitic diseases 67 (13%) and external causes 65 (12%). Deaths from maternal causes represented the antepenultimate cause of death. Were identified after analysis of the fields filled in Death Certificates, 467 (88%) not maternal deaths, 5 (1%) declared maternal and 60 (11%) presumed maternal deaths. Conclusion: The pattern of mortality in the municipality is similar to the country, pointing to the need for increased action in the three spheres of government focused on the health of the female population. Knowing the profile of women mortality in reproductive age furthers our understanding of their main demands and health problems, offering support for the planning of actions focused on reducing deaths from preventable causes.
