Background Plasmodium falciparum malaria is a threat to public health, but Plasmodium vivax malaria is most prevalent in Latin America, where the incidence rate has been increasing since 2016, particularly in Venezuela and Brazil. The Brazilian Amazon reported 193,000 cases in 2017, which were mostly confirmed as P. vivax (~ 90%). Herein, the relationships among malaria incidence rates and the proportion of accumulated deforestation were contrasted using data from the states of Acre and Rondônia in the south-western Brazilian Amazon. The main purpose is to test the hypothesis that the observed difference in incidence rates is associated with the proportion of accumulated deforestation. Methods An ecological study using spatial and temporal models for mapping and modelling malaria risk was performed. The municipalities of Acre and Rondônia were the spatial units of analysis, whereas month and year were the temporal units. The number of reported malaria cases from 2009 until 2015 were used to calculate the incidence rate per 1000 people at risk. Accumulated deforestation was calculated using publicly available satellite images. Geographically weighted regression was applied to provide a local model of the spatial heterogeneity of incidence rates. Time-series dynamic regression was applied to test the correlation of incidence rates and accumulated deforestation, adjusted by climate and socioeconomic factors. Results The malaria incidence rate declined in Rondônia but remained stable in Acre. There was a high and positive correlation between the decline in malaria and higher proportions of accumulated deforestation in Rondônia. Geographically weighted regression showed a complex relationship. As deforestation increased, malaria incidence also increased in Acre, while as deforestation increased, malaria incidence decreased in Rondônia. Time-series dynamic regression showed a positive association between malaria incidence and precipitation and accumulated deforestation, whereas the association was negative with the human development index in the westernmost areas of Acre. Conclusion Landscape modification caused by accumulated deforestation is an important driver of malaria incidence in the Brazilian Amazon. However, this relationship is not linearly correlated because it depends on the overall proportion of the land covered by forest. For regions that are partially degraded, forest cover becomes a less representative component in the landscape, causing the abovementioned non-linear relationship. In such a scenario, accumulated deforestation can lead to a decline in malaria incidence.
Heart Rate Variability (HRV) represents cardiac autonomic behavior and have been related to menopausal symptoms, mainly vasomotor symptoms and their imbalance to cardiovascular risk. It is not clear in the literature which index represents this imbalance and what is their involvement with the menopausal state. The aim of this study was to evaluate HRV in menopausal transition and post-menopausal symptoms with different intensities. This cross-sectional study was conducted in Rio Branco, State of Acre, Brazil from October 2016 to July 2017. We used Kupperman-Blatt Menopausal Index (KMI) to measure menopausal symptoms intensity. HRV analysis was performed based on the guidelines of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology. HRV is lower in the group with moderate/intense menopausal symptoms compared to mild symptoms.
Introdução: Os acidentes ofídicos são um problema de saúde pública e são considerados emergências clínicas, motivo este que torna os estudos em regiões de grande incidência muito importantes. Objetivo: Descrever os aspectos clínicos e epidemiológicos de pacientes vítimas de acidentes ofídicos em uma região da Amazônia Ocidental, Brasil. Método: Trata-se de um transversal, retrospectivo e documental de abordagem quantitativa, no período de 2015 a 2016, realizado no Hospital Regional do Juruá, localizado na cidade de Cruzeiro do Sul, Acre, Brasil. Os dados epidemiológicos foram obtidos a partir das fichas do Sistema de Informação de Agravos de Notificação (SINAN), no Setor de Vigilância Epidemiológica do hospital. Foram verificadas as seguintes variáveis: mês de ocorrência, identificação da serpente (tipo de acidente), local do acidente (zona urbana e rural), localidade, município, dados da vítima (faixa etária, sexo, região anatômica atingida), sintomas e sinais apresentados, circunstâncias do acidente, tempo decorrido entre o acidente e o atendimento, a quantidade de ampolas utilizadas e o tipo de soro no tratamento das vítimas. Resultados: Foram atendidos em média 124 casos de acidentes ofídicos por ano (76,71 casos por 100.000 habitantes/ano), sendo a maioria acidentes botrópicos e os pacientes constituídos por indivíduos adultos do sexo masculino e trabalhadores rurais, picados nos membros inferiores. Mais de 30% dos casos foram atendidos seis horas após o envenenamento e o atendimento após 24 horas é um fator de risco para complicações, uma vez que sete dos oito pacientes que apresentaram complicações foram atendidos depois de um dia do acidente. Conclusão: Apresentou um crescente constante nos casos, o que gerou um ponto de reflexão preocupante, que pode estar associado a dois fatores, onde um volta-se para a melhora no deslocamento das vítimas (melhorias nas estradas dos ramais e implantação de lancha do SAMU) facilitando mais o transporte e na cobertura de telefonia melhorando a comunicação, ou a falha das políticas de saúde pública na oferta de melhores condições e orientações para a população.
Introduction: The safety culture of the patient is a contributing factor for the maintenance of the user’s well-being in the health system because, through it, an organized systematization and quality of patient care are obtained, preventing possible intercurrences that can cause damages. Objective: To analyze the Patient Safety Culture (PSC) from the perspective of health professionals at the Reference Hospital of the Upper Juruá River, in the Brazilian Western Amazon. Methods: This is a cross-sectional study developed in a medium-sized public hospital in a municipality in Western Amazonia. The Survey for Patient Safety Culture survey of the Agency for Healthcare Research and Quality was applied to 280 professionals from December 2016 to February 2017. Descriptive analysis of the data and the internal consistency of the instrument were performed. Results: The results indicate the best evaluations in the dimensions of Teamwork in the scopes of the units (60%) and Organizational learning (60%). The aspects with the worst results were the dimensions of non-punitive responses to errors (18%) and frequency of events reported (32%). The internal reliability (Cronbach’s Alpha) analysis of the dimensions ranged from 0.35 to 0.90. Conclusion: The "culture of fear" seems to predominate in this hospital, however, the study showed that there is scope for improvement in all dimensions of CSP. The values of Cronbach’s Alpha presented similarity to the results obtained by the validation process.
We aimed to evaluate the accuracy of deterministic and stochastic statistical models by means of a protocol developed in a free programming environment for monthly time-series analysis of the incidence of confirmed dengue cases in the states and federal district of Brazil from January 2000 to December 2017. This was an ecological time-series study conducted to evaluate and validate the accuracy of 10 statistical models for predicting the new cases of dengue. Official data on the monthly cases of dengue from January 2000 to December 2016 were used to train the statistical models, while those for the period January–December 2017 were used to test the predictive capacity of the models by considering three forecasting horizons (12, 6, and 3 months). Deterministic models proved to be reliable for predicting dengue in a 12-month forecasting horizon, while stochastic models were reliable for predicting the disease in a 3-month forecasting horizon. We were able to reliably employ models for predicting dengue in the states and federal district of Brazil. Hence, we strongly recommend incorporating these models in state health services for predicting dengue and for decision-making with regard to the advanced planning of interventions before the emergence of epidemics.
Introduction: Fish accidents, called ichthyism, are common and considered a neglected health problem with high morbidity and low lethality. Noteworthy are the poisonings by freshwater stingrays, which are considered very serious and one of the most important injuries caused by aquatic animals in South America. Case Presentation: To describe an accident and vascular injury with venomous stingray animals in the Alto do Juruá, Acre, Brazil. Male patient admitted due to stingray in the left lower extremity 20 days ago. Conclusion: The freshwater stingray, due to its sharp characteristics, injured the great saphenous vein, requiring surgical intervention. The situation presented negative evolution due to the lack of necessary procedures in the first attendance, such as the proper cleaning of the wound and the removal of the sting.
Resumo Objetivo: Analisar fatores de risco para óbito em indivíduos com síndrome respiratória aguda grave por COVID-19. Métodos: Coorte retrospectiva, constituída de indivíduos adultos com COVID-19, de março a setembro de 2020, notificados pelo sistema de vigilância epidemiológica do estado do Acre, Brasil. Empregou-se regressão de Cox. Resultados: Entre 57.700 indivíduos analisados, a incidência foi de 2.765,4/100 mil habitantes, e a mortalidade, de 61,8/100 mil hab. Os fatores de risco para o óbito foram ser do sexo masculino (HR=1,48 - IC95% 1,25;1,76), ter idade ≥60 anos (HR=10,64 - IC95% 8,84;12,81), sintoma de dispneia (HR=4,20 - IC95% 3,44;5,12) e apresentar multimorbidade (HR=2,23 - IC95% 1,77;2,81), com destaque para cardiopatas e diabetes mellitus. Os sintomas ‘dor de garganta’ e ‘cefaleia’ estavam presentes nos casos leves da doença. Conclusão: Ser homem, idoso, apresentar cardiopatia, diabetes mellitus e dispneia foram características associadas ao óbito pela COVID-19.
The culture of patient safety should be considered a guiding principle for different areas of health. This research presents the results of an analysis on Patient Safety Culture (PSC), according to the perception of health professionals who work in the Psychosocial Care Network, through a descriptive observational cross-sectional study, using the Hospital Survey on Patient Safety Culture in a municipality in the Western Amazon of Brazil. Sixty-nine (69) professionals expressed that the best dimensions evaluated were: “expectations and actions to promote the safety of supervisors and managers” (75%) and “support from hospital management to patient safety” (64%). The worst evaluations were: “non-punitive responses to errors” (27%) and “general perceptions about patient safety” (35%), demonstrating that there still is a culture of fear of causing harm and the need for educational actions on patient safety. In general, all professionals have close contact with patients, regardless of the length on duty; however, the weekly workload and turnover in this sector is leading to a greater chance of errors. The analysis of the internal reliability of the dimensions ranged from 0.12 to 0.89. Only one-third of the respondents scored PSC as “Good” in the studied institutions and 63 out 69 professionals did not report any adverse events in the last 12 months. There are weaknesses in the observed perception of PSC and the obtained results show opportunities and challenges for improvements in the study system.
