Background: Despite Rheumatic Heart Disease (RHD) contributing to an estimated disease burden in 2019 of 40 million people and 285 500 deaths, few studies document the characteristics and outcomes in children. We undertook a sub-analysis of children from the multi-centre prospective two-year global Rheumatic Heart Disease Registry (REMEDY) to document their presentation, clinical characteristics and outcomes. Methods: Nine-hundred and twenty-one children were enrolled into the REMEDY registry among the 3,343 symptomatic RHD patients from 25 hospitals in 12 African countries, India and Yemen and followed up over 24 months to assess characteristics, complications and outcome. Results: More than half of the children enrolled in the REMEDY study presented with severe valvular heart disease; 60% had more than one valve involved, 30% were classified as NYHA class III/IV and 17.7% died within 24 months. Just over 20% of children were not on penicillin prophylaxis. Although 20% met criteria for surgery, only less than 9% (n=78, 8.5%) had had percutaneous or surgical intervention with half from upper-middle-income countries. The major risk factors associated with mortality included older age (Hazard Ratio (HR): 1.01, p=0.001) and atrial fibrillation or flutter (HR: 2.3, p=0.028). Female gender(HR: 0.68, p=0.062) and education level above primary school (HR: 0.88, p=0.68) did not confer significant protection. However, a past medical history of ARF conferred some protection against mortality (HR: 0.61, p=0.031). In follow-up, 30% (n=238, 29.6%) of children experienced an adverse cardiovascular event, nearly 15% (n=114, 14.1%) were hospitalised and six young women became pregnant during the study period. Conclusion: Children with RHD in low- and middle-income countries are severely affected, with significant mortality and morbidity. The use of penicillin was suboptimal and the substantial need for surgery is evident. Our findings support the recommendations of the World Health Assembly (WHA) Resolution 71.14 passed in May 2018 for consistent provision of penicillin, integrated collaborative efforts focused on children and adolescent health as well as access to specialised services including cardiac surgery.

Introdução: Estatísticas sobre a ocorrência de casos novos de câncer são fundamentais para o planejamento e monitoramento das ações de controle da doença. No estado de São Paulo, a incidência de câncer é obtida indiretamente por meio de estimativas oficiais (para o estado como um todo e sua capital) e, de forma direta, em municípios cobertos por Registro de Câncer de Base Populacional (RCBP). Existem, atualmente, três RCBP ativos (São Paulo, Jaú e Santos), um inativo (Barretos) e um em reimplantação (Campinas). Dado o desconhecimento do panorama da incidência de câncer em áreas não cobertas por RCBP, este estudo teve como objetivo estimar a incidência de câncer, calcular taxas brutas e padronizadas por idade, específicas por sexo e localização primária do tumor para as 17 Redes Regionais de Atenção à Saúde (RRAS) de São Paulo e municípios, em 2010. Método: Utilizou-se como estimador da incidência de câncer a razão Incidência/Mortalidade (I/M), por sexo, grupo etário quinquenal dos 0 aos 80 anos e localização primária do tumor. O numerador da razão foi formado pelo número agregado de casos novos entre 2006-2010, em dois RCBP ativos (Jaú e São Paulo, respectivamente, com cobertura correspondente a 0,3 por cento e 27,3 por cento da população estadual). No denominador, o número de óbitos oficial nas respectivas áreas e período. O número estimado de casos novos resultou da multiplicação das I/M pelo número de óbitos por câncer registrados em 2010 para o conjunto de municípios formadores de cada uma das RRAS ou para cada município. O método de referência foi aquele utilizado no Globocan series, da Agência Internacional de Pesquisa contra o Câncer. O ajuste por idade das taxas de incidência ocorreu pelo método direto, tendo como padrão a população mundial. Resultados: Estimaram-se 53.476 casos novos de câncer para o sexo masculino e 55.073 casos para o feminino (excluindo-se os casos de câncer de pele não melanoma), com taxas padronizadas de 261/100.000 e 217/100.000, respectivamente. No sexo masculino, a RRAS 6 apresentou para todos os cânceres a maior taxa de incidência padronizada (285/100.000), e a RRAS 10, a menor (207/100.000). Os cânceres mais incidentes em homens foram próstata (77/100.000), cólon/reto/anus (27/100.000) e traqueia/brônquio/pulmão (16/100.000). Entre as mulheres, as taxas de incidência padronizadas por idade foram de 170/100.000 (RRAS 11) a 252/100.000 (RRAS 07); o câncer de mama foi o mais incidente (58/100.000), seguido pelos tumores de cólon/reto/anus (23/100.000) e de colo uterino (9/100.000). Conclusões: Os resultados apontaram diferentes padrões de incidência com taxas que ultrapassaram a magnitude estadual. Dados provenientes de RCBP locais podem ser usados na obtenção indireta de estimativas regionais e locais. Neste estudo, as taxas de incidência apresentadas podem estar sub ou superestimadas refletindo a qualidade, completitude e padrões observados no RCBP de maior representatividade considerado na análise. / Introduction: Statistics on the occurrence of new cases of cancer are fundamental to the planning and monitoring of control measures. In Sao Paulo state, Brazil, cancer incidence can be obtained by the official estimates for the state as a whole and the capital and in municipalities covered by Population Based Cancer Registries (PBCR). The currently panorama of PBCR in Sao Paulo includes three active registries, one retired and one in re-deployment. Given the unknown cancer incidence in areas not covered by PBCR, this study aimed to estimate cancer incidence (standardized incidence rates = SIR) according to gender, age group and tumor type for 17 Regional Networks of Health Care (RNHC) and municipalities in São Paulo state, Brazil, in 2010. Methods: We used as estimator the Incidence:Mortality ratio (I:M) adjusted for sex, five-year age group (0-80 years) and primary tumor site. The ratio numerator was composed by the aggregated number of new cases diagnosed in 2006-2010 in two active PBCR, Jau and Sao Paulo, covering 0.3 per cent and 27.3 per cent of the state population, respectively, while the denominator was the official number of cancer deaths in the same areas and period. The estimated number of incident cases resulted from the multiplication of I:M by the number of deaths registered in 2010 for the set of municipalities that compose the region or for each local area. The reference method was the one used in Globocan series of the International Agency for Research on Cancer. Results: We had estimated a total of 53,476 new cases of cancer for males and 55,073 cases for females (excluding non melanoma skin cancers) in the state of São Paulo, corresponding to standardized rates (world population) of 261/100,000 and 217/100,000, respectively. Among males, RNHC-6 presented the highest standardized incidence rate of all cancers (285/100,000) and the RNHC-10, the lowest (207/100,000). Most frequent tumor sites in men were: prostate (SIR=77/100,000), colorectum/anus (SIR=27/100,000) and trachea/bronchus/lung (SIR=16/100,000). Among women, rates for all cancers excluding non-melanoma skin varied from 170/100,000 (RNHC-11) to 252/100,000 (RNHC-7); breast cancer was the most incident cancer site (SIR=58/100,000), followed by colorectum/anus (SIR=23/100,000) and cervix (SIR=9/100,000). Conclusions: Our results showed different patterns of regional incidence with rates that often exceeded the values presented for the state. Data from local PBCR can be used to obtain regional and local estimates. However, the estimated rates may be under- or overestimated reflecting the quality, completeness and the patterns observed in the most representative registry used in the analysis.

Les services Web (SW) sont considérés comme étant un bloc pilier pour la réalisation de transactions électroniques entre entreprises. Ainsi, de plus en plus d'entreprises utilisent des SW pour réaliser des transactions avec leurs partenaires et/ou offrir des services en ligne. Dans un tel contexte, chaque entreprise possède un ou plusieurs référentiels privés de descriptions de SW. Pour que ses SW soient consultables et puissent être découverts par d'autres entreprises, une entreprise devra rendre ses référentiels de SW publics. La solution couramment utilisée consiste à publier les descriptions de ses SW dans des annuaires de SW. En conséquence, le nombre d'annuaires disponibles peut être aussi important que le grand nombre d'entreprises et la découverte d'un SW devient ainsi une tâche fastidieuse pour un demandeur de services et coûteuse pour un système de découverte. L'objectif principal de cette thèse est de fournir des solutions pour assurer une découverte d'annuaires de SW adaptée à un environnement distribué. Pour ce faire, nous proposons tout d'abord d'organiser le réseau d'annuaires en communautés. Ensuite, afin de préserver la consistance de cette organisation face aux changements qui peuvent se produire (départ/arrivée d'annuaires), nous définissons les mécanismes de gestion nécessaires. Enfin, nous proposons une approche pour la découverte d'annuaires de SW qui utilise deux filtres pour limiter l'espace de recherche d'un demandeur de services. Les solutions proposées ont été testées par la mise en place d'un réseau de communautés d'annuaires, l'implémentation d'un gestionnaire de communautés et d'un système de découverte d'annuaires. / Web services (WS) can be seen as a pillar block for achieving electronic B2B transactions. More and more companies are using WS to achieve transactions with their partners and/or offer on-line services. These companies have to make their WS available for consultation through their own private WS registries. As a result, the number of WS registries that are made available for use can be as many as the large number of companies. This raises an old, search engine, problem in a new form: discovery mechanisms of WS are not efficient both in response times and quality of results. In this context, if appropriate solutions are not considered, "traditional" WS discovery mechanisms that consist of scanning all the registries would for instance slow down the increase rate of WS. In this thesis, we are interested in WS discovery in a distributed registry environment. To do this, we first propose to organize a registries network into communities based on functionalities offered by the WS of a registry. Then, to handle the dynamic nature of communities and their members, we define the needed management mechanisms to monitor changes and reconcile potential conflicts. Finally, we propose an approach for WS registries discovery that uses two filters to limit the search space. We first use the functional requirement of a service requester to select the appropriate registry community. Then we use the requester's non-functional requirements and his behavior to select the registries. The proposed solutions were tested by setting up a P2P network of registry communities, implementing a community manager and a discovery system.

The origin of cancer registries was to create clinical surveys and perform patient follow-up, the objective being to bring surgical patients back to the doctor periodically to identify recurrences. Over the past 60 years, cancer registries have continued to compile patient care data and perform patient follow-up. However, over the past decade, emphasis has been placed on the direct involvement of the cancer registry in monitoring quality of care. In contrast, stroke registries monitor the quality of care for patients, but do not follow them periodically to identify recurrences. The biology of these diseases is an intricate part of the different roles played by both types of registries, yet each has a page to take from the other's book. This article examines the manner in which these registries operate to improve the quality of patient care.

Introduction: The Mortality–Incidence Ratio complement [1 – MIR] is an indicator validated in various populations to estimate five-year cancer survival, but its validity remains unreported in Peru. This study aims to determine if the MIR correlates directly with five-year survival in patients diagnosed with the ten most common types of cancer in metropolitan Lima. Materials and methods: The Metropolitan Lima Cancer Registry (RCLM in Spanish) for 2004–2005 was used to determine the number of new cases and the number of deaths of the following cancers: breast, stomach, prostate, thyroid, lung, colon, cervical, and liver cancers, as well as non-Hodgkin’s lymphoma and leukaemia. To determine the five-year survival, the five-year vital status of cases recorded was verified in the National Registry of Identification and Civil Status (RENIEC in Spanish). A linear regression model was used to assess the correlation between [1 – MIR] and total observed five-year survival for the selected cancers. Results: Observed and estimated five-year survival determined by [1 – MIR] for each neoplasia were thyroid (66.7%, 86.7%), breast (69.6%; 68%), prostate (64.3%, 63.8%) and cervical (50.1%, 58.5%), respectively. Pearson’s r coefficient for the correlation between [MIR – 1] and observed survival was = 0.9839. Using the coefficient of determination, it was found that [1 – MIR] (X) captures the 96.82% of observed survival (Y). Conclusion: The Mortality–Incidence Ratio complement [1 – MIR] is an appropriate tool for approximating observed five-year survival for the ten types of cancers studied. This study demonstrates the validity of this model for predicting five-year survival in cancer patients in metropolitan Lima.

Parentage testing in the domestic dog is finding increasing application for dog breed registries as well as in research. The aim of parentage verification is the correct assignment of both parents to the offspring. For accurate parentage verification informative microsatellite markers have to be identified. More powerful models to study artificial insemination in bitches will be possible if the paternity and gender of early dog conceptuses can be determined. The amelogenin gene locus has been used in bovine day six to day seven embryos for early gender determination but no research has been done on early conceptuses of the domestic dog. The aim of the current study was to establish an accurate method for parentage and gender determination from domestic dog conceptuses during early pregnancy in a multi-sire insemination trial. Semen from 10 male dogs was used in each of 12 females for artificial insemination. Blood and uterine tissue for DNA extraction was collected from males and females, and embryonic material was collected after ovariohysterectomy between 16 and 30 days after the onset of cytological dioestrus. Twenty-three microsatellite markers were used for parentage verification, and the amelogenin gene locus for gender determination. Mean observed heterozygosity, mean expected heterozygosity (HExp), and mean PIC were high (0.6753, 0.6785, and 0.628, respectively). There were 66 conceptuses. In two, neither parentage nor gender could be established because their tissue samples were contaminated. Parentage could be assigned by CERVUS 3.0.3 in 42 out of 64 of the cases (66%) without difficulty. Another 33% of the cases (21 out of 64) could be resolved using the number of exclusions, LOD scores or manual verification of genotyping errors. In one conceptus, paternity could not be established because its sire may have been either of two siblings. The gender of the female and male dogs was successfully confirmed using the amelogenin gene locus. The gender of the conceptuses was determined using the amelogenin gene locus (50% male, 50% female) but not confirmed by another method of gender determination such as karyotyping. As shown in the current study, the panel of 24 microsatellite markers used provides high information content suitable for parentage verification in multi-sire litters, as well as gender determination of early conceptuses. / Dissertation (MSc)--University of Pretoria, 2010. / Production Animal Studies / unrestricted
