Cartography of neoplasms in dogs from different regions of the city of São Paulo, SP, Brazil: a survey (2002-2003) of data from the Veterinary Hospital of the School of Veterinary Medicine and Animal Science of the University of São Paulo, Brazil

Avanços na medicina veterinária resultaram em benefícios significativos na vida de animais de estimação nos últimos 20 anos, e o aumento da expectativa de vida para animais levou a uma maior prevalência de neoplasias em cães. A Epidemiologia do Câncer e as ferramentas de análise espacial, embora bem desenvolvidas na pesquisa oncológica humana, estão começando a serem exploradas na Oncologia Veterinária. A cidade de São Paulo, capital do estado de São Paulo, Brasil, é dividida em cinco regiões: Norte, Sul, Leste, Oeste e centro. O Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (HOVET-SVMAS-USP) está localizado na região Oeste de São Paulo, Brasil, e admite casos de pequenos e grandes animais. Tumores mamários caninos são tão numerosos que não são tratados na rotina do HOVET. O objetivo deste trabalho foi realizar um estudo cartográfico para descrever a distribuição espacial dos casos prevalentes de neoplasias em cães a partir do HOVET. Dos 3.620 casos atendidos em 2002 e 2003, 380 (10,5%) casos eram de cães acometidos por tumores benignos e malignos. Não foi encontrada diferença estatística entre a distribuição dos 380 endereços entre as cinco regiões da cidade. Os resultados mostraram que o HOVET atende pacientes caninos de todas as regiões de São Paulo e que há uma distribuição espacial homogênea das neoplasias. Os autores incentivam estudos mais amplos, envolvendo vários hospitais veterinários, clínicas e laboratórios, a fim de obter dados mais precisos sobre a distribuição das neoplasias caninas em São Paulo, SP, Brasil.Improvements in veterinary medicine have resulted in a significant benefit in the life of pets in the last 20 years, and increased pet life expectancy led to an increased prevalence of canine neoplasia. Cancer epidemiology and spatial analysis tools, although well developed for human oncology research, is just beginning to be explored in veterinary oncology. São Paulo city, capital of the state of São Paulo, Brazil, is divided into five regions: North, South, East, West and downtown. The Veterinary Hospital of the School of Veterinary Medicine and Animal Science, University of São Paulo (HOVET-SVMAS-USP), is located in the West region of São Paulo, Brazil, and admits cases of small and large animals. Canine mammary tumors are so numerous that they are not routinely treated at the HOVET. The aim of this work was to perform a cartographic study to describe the spatial distribution of prevalent cases of neoplasms in dogs from the HOVET. Of the 3,620 cases seen in 2002 and 2003, 380 cases (10.5%) were of dogs affected with benign and malignant neoplasms. No statistical difference was found for the 380 addresses distributed among the five regions of the city. These results showed that the HOVET receives canine patients from all regions of São Paulo and there is a homogeneous spatial distribution of neoplasms. Authors encourage additional broader studies, involving several veterinary hospitals, clinics or laboratories in order to obtain more accurate data on distribution of canine neoplasms in São Paulo, SP, Brazil

Role of uncontrolled HIV RNA level and immunodeficiency in the occurrence of malignancy in HIV-infected patients during the combination antiretroviral therapy era: Agence Nationale de Recherche sur le Sida (ANRS) CO3 Aquitaine Cohort.: Malignancy, HIV and immune deficiency

International audienceBACKGROUND: Human immunodeficiency virus (HIV)-infected patients are at higher risk of malignancies. In addition to traditional determinants, a specific deleterious effect of HIV and immunodeficiency is speculated. We aimed at studying the association between immunological and virological characteristics of HIV-infected patients in care and the risk of acquired immunodeficiency syndrome (AIDS)-defining and non-AIDS-defining malignancies. METHODS: Patients consecutively enrolled in the hospital-based Agence Nationale de Recherche sur le Sida (ANRS) CO3 Aquitaine Cohort were included if the duration of follow-up was >3 months during the period 1998-2006. Multivariate modeling used an extended Cox proportional hazards model for time-dependent covariates and delayed entry. RESULTS: The 4194 patients included in the study developed 251 first malignancies during 22,389 person-years. A higher incidence of AIDS-defining malignancies (107 cases) was independently associated with (1) both longer and current exposures to a plasma HIV RNA level >500 copies/mL (hazard ratio [HR], 1.27 per year [P500 cells/mm(3) to prevent the occurrence of malignancy, this should be integrated to malignancy-prevention policies

Tobacco use and its determinants in HIV-infected patients on antiretroviral therapy in West African countries.: Tobacco use in HIV-infected patients in West Africa

International audienceBACKGROUND: Tobacco smoking is common in human immunodeficiency virus (HIV) infected patients from industrialised countries. In West Africa, few data concerning tobacco consumption exist. METHODS: A cross-sectional survey of the International Epidemiological Database to Evaluate AIDS (IeDEA) network in West Africa was conducted. Health workers administered a questionnaire assessing tobacco and cannabis consumption among patients receiving antiretroviral treatment. Regular smokers were defined as current smokers who smoked >1 cigarette per day for >or=1 year. RESULTS: Overall, 2920 patients were enrolled in three countries. The prevalence of ever smokers and regular smokers were respectively 46.2% (95%CI 42.8-49.5) and 15.6% (95%CI 13.2-18.0) in men and 3.7% (95%CI 2.9-4.5) and 0.6% (95%CI 0.3-0.9) in women. Regular smoking was associated with being from Côte d'Ivoire or Mali compared to Benin (OR 4.6, 95%CI 2.9-7.3 and 7.7, 95%CI 4.4-13.6), severely impaired immunological status at highly active antiretroviral treatment initiation (OR 1.5, 95%CI 1.1-2.2) and history of tuberculosis (TB; OR 1.8, 95%CI 1.1-3.0). CONCLUSION: There are marked differences in smoking prevalence among these West African countries. This survey approach also provides proof of the association between cigarette smoking and TB in HIV-infected patients, a major public health issue in this part of the world
