ABSTRACT BACKGROUND: The Respiratory Syndromes Surveillance System was created by the Brazilian Ministry of Health in 2000 to monitor influenza in this country. With the emergence of the new coronavirus pandemic, it became incorporated into the surveillance network for influenza and other respiratory viruses. OBJECTIVE: To analyze the transmission of coronavirus disease 2019 (COVID-19) and severe acute respiratory syndrome (SARS) in the state of Acre through its hierarchical urban network. DESIGN AND SETTING: Cross-sectional, descriptive and ecological study, using a spatiotemporal approach and using secondary data. This study was conducted in the state of Acre, northern Brazil. METHODS: This study used secondary data, and epidemiological weeks and municipalities were taken to be the units of analysis. Incidence rates and kernel intensities were calculated for four study periods. Spatiotemporal analysis was performed using scan statistics to identify clusters of SARS cases and considering the population of each municipality. RESULTS: In general, it could be observed that there were higher kernel rates and intensities in municipalities located in the north and south of this state (i.e. its most populous municipalities). CONCLUSION: Priority areas for interventions to control transmission of COVID-19 were highlighted, with the aim of reducing the risks of transmission to more distant areas in the urban hierarchy of the state of Acre.

Objective: To describe the methodological and operational aspects of the Cancer Surveillance Project and its associated factors: population-based and hospital-based registry (VIGICAN), in Mato Grosso (MT). Methods: VIGICAN was divided into two projects: an extension one, which updated the data from the Population-Based Cancer Registry (RCBP) of MT in the period 2008 to 2016; and one of research, which collected primary data, through individual interviews and analysis of medical records of people with a diagnosis of cancer, aged 18 years or over, treated at reference hospitals for oncology. To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, status and health behavior, and environmental exposure. Results: In the períod from 2008 to 2016, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the RCBP Cuiabá and Interior. After validation procedures, fifty thousand incident cases were chosen. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in the interior of the state and 1.4% in other states. Preliminary data revealed that the majority were female (55.0%) and younger than 60 years (54.3%). Among those interviewed, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%) and 32.7% lived close to crops. Conclusion: The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.

Objetivo: Descrever os aspectos metodológicos e operacionais do Projeto Vigilância do Câncer e seus fatores associados: registro de base populacional e hospitalar (VIGICAN), em Mato Grosso (MT). Métodos: O VIGICAN se desdobrou em dois projetos: um de extensão, que atualizou os dados dos Registros de Câncer de Base Populacional (RCBP) de MT no período de 2008 a 2016; e um de pesquisa, que coletou dados primários, por meio de entrevistas individuais e análise de prontuários de pessoas com diagnóstico de câncer, com 18 anos ou mais, atendidas em hospitais de referência para oncologia. Para analisar os fatores associados ao câncer, foram coletadas as seguintes variáveis: socioeconômicas e demográficas, suporte social, situação e comportamentos de saúde e exposição ambiental. Resultados: No período de 2008 a 2016, foram notificados nos RCBP Cuiabá e Interior, aproximadamente, 100 mil casos de câncer (incidentes e prevalentes). Após procedimentos de validação, foram eleitos 50 mil casos incidentes. A pesquisa entrevistou 1.012 pacientes, sendo 38,2% residentes nos municípios de Cuiabá e Várzea Grande, 60,4% no interior do estado e 1,4% em outros estados. Os dados preliminares revelaram que a maioria era do sexo feminino (55,0%) e tinha menos de 60 anos (54,3%). Entre os entrevistados, 7,2% relataram fumar tabaco, 15,5% consumiam bebidas alcoólicas (15,5%) e 32,7% moravam próximos a lavouras. Conclusão: O desenvolvimento desses projetos permitiu a integração do ensino com os serviços de saúde e possibilitará o reconhecimento das especificidades e diferentes cenários de exposição e fatores associados ao câncer do território mato-grossense.

Objective: To describe the mortality trend from all causes of cancer and the five main causes in the state of Mato Grosso, Brazil, from 2000 to 2015. Methods: This is a descriptive, ecological, time series study, with data referring to deaths of residents of Mato Grosso due to neoplasms (ICD-10 codes C00 to C97), from the Mortality Information System (SIM). Time trend analyzes of the standardized mortality rate from all causes of cancer and five specific causes of cancer (lung, prostate, breast, colorectal and cervix) for the state and according to macroregions (South, West, North, East and Center -North) were performed using linear regression (p-value<0.05). Results: From 2000 to 2015, 28,525 deaths from all causes of cancer in residents of the state of Mato Grosso were recorded. An increasing trend was observed for all causes of cancer, in addition to lung, breast and colorectal cancers. Southern and Northern macroregions showed an increasing trend for all causes, breast and colorectal; North-Central for breast and colorectal. East was increasing for all causes, prostate and colorectal, and decreasing for cervix. Conclusions: In the state of Mato Grosso, there was an increasing trend in mortality from all causes of cancer and from specific causes, with emphasis on breast and colorectal cancer in most macroregions.

Objective: To analyze the trend of standardized rate due to mortality by cancer in the state of Mato Grosso, according to health regions, from 2000 to 2015. Methods: Ecological study of time series with data on deaths by cancer from the Mortality Information System. The rates were standardized using direct method and calculated by year and health regions. The annual percentage change (APC) and its respective confidence interval (CI 95%) were obtained through simple linear regression. Thematic maps were built to describe the rates spatial distribution. Results: There were 28,525 deaths by cancer registered in Mato Grosso and the five main causes were lung, prostate, stomach, breast and liver cancer. The highest mortality rates were found in the Médio Norte, Baixada Cuiabana and Sul Matogrossense regions. From 2000 to 2015 a growing trend was observed in the mortality rate by cancer in Mato Grosso (APC=0.81%; CI95%: 0.38; 1.26), and in four health regions, Garças Araguaia (APC=2.27%; CI95%: 1.46; 3.08), Sul Matogrossense (APC=1.12%; CI95%: 0.28; 1.97), Teles Pires (APC=1.93%; IC95%: 0,11; 3,74) and Vale dos Arinos (APC=2.61%; CI95%: 1.10; 4.70), the oter regions presented stability. Conclusion: In the state of Mato Grosso and in the four health regions there was verified a growing trend of mortality due to cancer. The results indicate the need to consider the regional differences regarding actions for cancer prevention, control and assistance.

ABSTRACT Coronavirus is a family of viruses that cause respiratory infections. From cases first recorded in China at the end of 2019, a new type of virus in this family, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was discovered. The disease caused by this virus, COVID-19, was brought into Brazil by people in social classes with greater purchasing power, but groups with larger demographic dimensions have tended to become more affected over time. Poor sanitation can generate risky situations and behavior among people who live in spaces with characteristics that limit their quality of life. Installation of piped water in homes and basic education for the population are fundamental measures for disease control, including in relation to COVID-19. In this updating article, the COVID-19 pandemic was analyzed in the context of iniquities in Brazil (comparing these with the situation in other countries). A bibliographic search of texts relating to basic sanitation, socioeconomic development and transmission of COVID-19 in Brazil and worldwide was conducted.

Resumo No Brasil, a região Centro-Oeste tem apresentado aumento no número de casos de leishmaniose visceral humana (LVH) e canina (LVC). Com isso, o objetivo deste estudo foi avaliar a percepção da população em relação à doença, aos fatores associados a LVC, à distribuição espacial e à prevalência de anticorpos anti-Leishmania spp. em 385 cães, a partir do teste rápido imunocromatográfico e ensaio imunoenzimático (ELISA). Das 385 amostras, 54 foram reagentes para LVC e confirmadas no ELISA, correspondendo a prevalência de 14%. O conhecimento dos sinais da LVC pelos tutores (p = 0,038), a ocorrência prévia da LVC na vizinhança (p = 0,022), o cão sintomático (p = 0,014), esplenomegalia (p = 0,055) e apresentar úlcera em ponta de orelha (p = 0,059) foram significativamente associados à LVC. Os resultados demonstram expressiva prevalência de LVC, distribuídas espacialmente no contexto rural e urbano, e a associação de variáveis relacionadas ao ambiente e à percepção com a ocorrência da LVC ressaltam a importância da implementação de estratégias de controle e prevenção, focadas principalmente no manejo ambiental e em atividades de educação em saúde.

Abstract The midwest region of Brazil has witnessed an increase in the number of cases of human (HVL) and canine visceral leishmaniasis (CVL). The aim of the present study was to evaluate the population’s perception of these diseases, factors associated with CVL, its spatial distribution, and the prevalence of anti-Leishmania spp. in 385 dogs, determined using a commercially available immunochromatographic rapid test and confirmed using enzyme-linked immunosorbent assay (ELISA). Of the 385 samples, 54 were positive for CVL and confirmed by ELISA, corresponding to a prevalence of 14%. Knowledge of signs of CVL by tutors (p = 0.038); previous occurrence of CVL in the vicinity (p = 0.022); symptomatic dog(s) (p = 0.014), splenomegaly (p = 0.055), and ear ulcer(s) (p = 0.059) were significantly associated with CVL. The results revealed a significant prevalence of CVL spatially distributed in rural and urban contexts. The association between environmentally related variables and perception and the occurrence of CVL underscores the importance of implementing control and prevention strategies primarily focused on environmental management and health education activities.

Abstract INTRODUCTION: The fish farming program in Acre is as an alternative program to generate income and employment and has promising regional, national, and international markets. While the economic importance of fish farming in the Jurua Region is clear, one must address its contribution to increase malaria transmission. METHODS This was a qualitative study. The answers of the 16 key informants were organized into the following: (1) the healthcare services structure; (2) conscience, perception, and behaviors; and (3) socioeconomic and political issues. Each answer was classified as weaknesses, strengths, opportunities, and threats. RESULTS Regarding healthcare services, the frequency of household visits was reduced, and subjects presenting with malaria symptoms were required to visit a healthcare unit to be diagnosed and treated. Regarding individual’s conscience, perception, and behavior, malaria was considered an insignificant disease, and a large proportion of the population were engaged in health practices that put them at risk in contacting with malaria vectors. Regarding political and economic issues, there were economic and infrastructure barriers for the development of a productive activity, and the insufficient credit or formalization of their properties prevented their access to governmental incentives and the financial market. CONCLUSIONS Support to fish farmers for low-cost inputs was not observed, and appropriate knowledge regarding the impact of the absence of maintenance and abandonment of fish tanks was insufficient. Moreover, insufficient healthcare services prevented not only the treatment of individuals with malaria but also the control of this disease.
