Sanitizer residues in the milk of cows which had passed through footbaths

Copper sulfate and sodium hypochlorite are used in footbath solutions for the prevention and treatment of bovine digital diseases; however, data on the residues of such elements in milk are sparse in Brazil. This study evaluated the cost of applying the footbath treatment and the total amount of copper and chlorite residues in the milk of healthy cows after they had passed through these footbath solutions. Two groups of 7 cows each (GI and GII) were studied. In the case of GI, 1% sodium hypochlorite was used and for GII 5% copper sulfate was employed in the footbath. The milk samples were collected before the 7-day footbath treatment period (M0) and 24 h (M1), 48 h (M2), 72 h (M3) and 15 days (M15) after the last footbath. Statistical analysis to compare the different samples within each group was carried out by applying Friedman's test, followed by Dunn's test (p<0.05). It was concluded that the amount of total chlorites and copper in the milk of healthy cattle after routine daily footbaths for a period of 7 days presented some variations. However, the concentrations observed were considered insufficient to represent a risk to human health. The cost of the footbath solutions was found to be reasonable.

Avaliação do grau de satisfação entre os usuários de amplificação de tecnologia analógica e digital

OBJETIVO: objetivo desta pesquisa foi investigar o grau de satisfação entre os usuários de Aparelho de Amplificação Sonora (AAS) de tecnologia analógica e digital. FORMA DE ESTUDO: clínico com coorte transversal. MATERIAL E MÉTODO: A amostra foi constituída de 40 usuários de AAS unilateral, sendo 20 de tecnologia analógica (Grupo I) e 20 de tecnologia digital (Grupo II). Os indivíduos são portadores de perda auditiva neurossensorial, de configuração plana, de grau leve a moderado, com idade entre 40 e 95 anos. O instrumento de avaliação utilizado foi o International Outcome Inventory for Hearing Aids (IOI-HA - Versão em Português) proposto por Cox et al. (2002). RESULTADOS: Os resultados mostraram que os usuários do Grupo II utilizam o AAS por mais tempo diariamente e também apresentam um grau de dificuldade menor em determinadas situações com o uso da amplificação, comparado aos usuários do Grupo I. Os usuários do Grupo II relatam que sua perda auditiva não afeta em nada sua relação com terceiros. CONCLUSÃO: Apesar de os resultados revelarem que os usuários do Grupo I apresentam um handicap auditivo mais acentuado comparado aos usuários do Grupo II, o grau de satisfação com relação à amplificação não apresenta diferença significativa entre os dois grupos.

Internet e participação: o caso do orçamento participativo digital de Belo Horizonte

Este artigo investiga as representações sociais que emergem da participação pública mediada pelo uso de Tecnologias de Informação e Comunicação (TIC). A prefeitura de Belo Horizonte, em 2006, usou pela primeira vez a TIC no Orçamento Participativo Digital (OP Digital). Foi uma escolha da população das obras prioritárias para o biênio seguinte. O OP Digital foi repetido em 2008 e 2011, mas com participação inferior à obtida na primeira edição. Realizamos este trabalho para compreender o uso da internet pelo cidadão na tomada de decisão pública e para explicar a diminuição da sua participação. Os procedimentos metodológicos estão ancorados na teoria das representações sociais e na análise crítica do discurso de 101 textos - da imprensa e de órgãos públicos ou representantes do governo. Os resultados nos indicam que não está sendo explorado o potencial de interação e construção coletiva da internet, ancorando a nova prática em uma votação, dessa forma, trivializando-a. Essa pode ser uma das razões para o abandono da participação.

Sentidos e significados da participação democrática através da Internet: uma análise da experiência do Orçamento Participativo Digital

Este trabalho analisa três edições (2006, 2008 e 2011) do Orçamento Participativo Digital (OPD) de Belo Horizonte (MG). Objetiva deslindar os sentidos e significados da participação democrática mediada pela internet nessa experiência. Utiliza-se como método o estudo de caso único, de natureza qualitativa. Os dados foram coletados por meio de observação direta nos sítios do OPD e análise documental. Durante a fase de observação direta foram coletadas mensagens e manifestações dos cidadãos que estavam participando do processo. Tais dados foram tratados com o software Atlas TI 6.0®. Conclui-se que tanto o sentido quanto o significado democrático dessa experiência de participação mediadas pela internet são modificados ao longo das edições, indo de grandes impulsos de esperança democrática até a descrença nessa modalidade de participação digital.

Cross-cultural differences in children's concepts of health and illness

INTRODUCTION: In spite of general agreement that cross-cultural research is needed in the health area, most existing investigations of children's development of health and illness-related concepts have involved samples from developed countries. The study examined the development of the concepts of health and illness as a function of subject's age, socio-economic status (SES), gender and grade level in a Brazilian sample of 96 elementary and junior high school students. METHODS: Subjects were interviewed individually and their ideas of health and illness were assessed through open-ended questions. Participants' answers were transcribed verbatim and subjected to content analysis. RESULTS: Chi-square analyses revealed significant age, school grade and SES-related differences in participants' concepts of health and illness. DISCUSSION AND CONCLUSION: The themes employed by subjects to define both health and illness were broadly consistent with those found by previous research. The study showed a predictable relationship between subject's age and school grade level and increasingly more highly differentiated and multidimensional concepts of health and illness. This investigation suggests that, for the most part, cross-cultural similarities in children's concepts of health and illness may be more striking than the differences.

Causal attributions in Brazilian children's reasoning about health and illness

INTRODUCTION: At a time when a great number of diseases can be prevented by changing one's habits and life style, investigations have focused on understanding what adults and children believe to be desirable health practices and uncovering the factors associated with successful adherence to such practices. For these, causal attributions for health and illness were investigated among 96 Brazilian elementary school students. METHODS: Ninety six subjects, aged 6 to 14, were interviewed individually and their causal attributions were assessed through 14 true-false items (e.g. people stay well [healthy] because they are lucky). The relationship between the children's causal attributions and demographic characteristics were also examined. RESULTS: Overall, the results were consistent with previous researches. "Taking care of oneself" was considered the most important cause of good health. "Viruses and germs" and "lack of self-care" were the most selected causes of illness. Analyses revealed significant relationship between subjects' causal attribution and their age, school grade level, socioeconomic status and gender. CONCLUSIONS: The study findings suggest that there may be more cross-cultural similarities than differences in children's causal attributions for health and illness. Finding ways to help individuals engage in appropriate preventive-maintenance health practices without developing an exaggerated notion that the individuals can control their own health and illness is a challenge which remains to be addressed by further research.

Integrated Management of Childhood Illness: efficiency of primary health in Northeast Brazil

OBJECTIVE: The Integrated Management of Childhood Illness is a strategy designed to address major causes of child mortality. The aim of this study was to assess the impact of the strategy on the quality of child health care provided at primary facilities. METHODS: Child health quality of care and costs were compared in four states in Northeastern Brazil, in 2001. There were studied 48 health facilities considered to have had stable strategy implementation at least two years before the start of study, with 48 matched comparison facilities in the same states. A single measure of correct management of sick children was used to assess care provided to all sick children. Costs included all resources at the national, state, local and facility levels associated with child health care. RESULTS: Facilities providing strategy-based care had significantly better management of sick children at no additional cost to municipalities relative to the comparison municipalities. At strategy facilities 72% of children were correctly managed compared with 56% in comparison facilities (p=0.001). The cost per child managed correctly was US$13.20 versus US$21.05 in the strategy and comparison municipalities, respectively, after standardization for population size. CONCLUSIONS: The strategy improves the efficiency of primary facilities in Northeastern Brazil. It leads to better health outcomes at no extra cost.

Access to medicines for acute illness in middle income countries in Central America

OBJECTIVE : To analyze the main predictors of access to medicines for persons who experienced acute health conditions. METHODS : This was a cross-sectional analytic study, based on data from household surveys. We examined the predictors of: (1) seeking care for acute illness in the formal health care system and (2) obtaining all medicines sought for the acute condition. RESULTS : The significant predictors of seeking health care for acute illnesses were urban geographic location, head of household with secondary school education or above, age under 15, severity of illness perceived by the respondent, and having health insurance. The most important predictor of obtaining full access to medicines was seeking care in the formal health care system. People who sought care in the formal system were three times more likely to receive all the medicines sought (OR 3.0, 95%CI 2.3;4.0). For those who sought care in the formal health system, the strongest predictors of full access to medicines were seeking care in the private sector, having secondary school education or above, and positive perceptions of quality of health care and medicines in public sector health facilities. For patients who did not seek care in the formal health system, full access to medicines was more likely in Honduras or Nicaragua than in Guatemala. Urban geographic location, higher economic status, and male gender were also significant predictors. CONCLUSIONS : A substantial part of the population in these three countries sought and obtained medicines outside of the formal health care system, which may compromise quality of care and pose a risk to patients. Determinants of full access to medicines inside and outside the formal health care system differ, and thus may require different strategies to improve access to medicines. 

Digital disease detection and participatory surveillance: overview and perspectives for Brazil

ABSTRACT This study aimed to describe the digital disease detection and participatory surveillance in different countries. The systems or platforms consolidated in the scientific field were analyzed by describing the strategy, type of data source, main objectives, and manner of interaction with users. Eleven systems or platforms, developed from 1996 to 2016, were analyzed. There was a higher frequency of data mining on the web and active crowdsourcing as well as a trend in the use of mobile applications. It is important to provoke debate in the academia and health services for the evolution of methods and insights into participatory surveillance in the digital age.

Chagasic meningoencephalitis: case report of a recently included AIDS-defining illness in Brazil

Recently, reactivation of Chagas disease (meningoencephalitis and/or myocarditis) was included in the list of AIDS-defining illnesses in Brazil. We report a case of a 52-year-old patient with no history of previous disease who presented acute meningoencephalitis. Direct examination of blood and cerebrospinal fluid (CSF) showed Trypanosoma cruzi. CSF culture confirmed the diagnosis. Serological assays for T. cruzi and human immunodeficiency virus (HIV) were positive. Despite treatment with benznidazol and supportive measures, the patient died 24 hours after hospital admission. In endemic areas, reactivation of Chagas disease should always be considered in the differential diagnosis of meningoencephalitis among HIV-infected patients, and its presence is indicative of AIDS.

Syndromic surveillance: etiologic study of acute febrile illness in dengue suspicious cases with negative serology. Brazil, Federal District, 2008

With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples that remained negative for dengue (n = 127) were tested for rubella, with 3.9% (n = 5) positive results. Among those non reactive for rubella (n = 122), tests were made for leptospirosis and hantavirus. Positive tests for leptospirosis were 13.9% (n = 17) and none for hantavirus. Non reactive results (70.8%) were considered as Indefinite Febrile Illness (IFI). Low schooling was statistically associated with dengue, rubella and leptospirosis (p = 0.009), dyspnea was statistically associated with dengue and leptospirosis (p = 0.012), and exanthem/petechia with dengue and rubella (p = 0.001). Among those with leptospirosis, activities in empty or vacant lots showed statistical association with the disease (p = 0.013). Syndromic surveillance was shown to be an important tool in the etiologic identification of IFI in the Federal District of Brazil.

A questionnaire to evaluate the impact of chronic diseases: validated translation and Illness Effects Questionnaire (IEQ) reliability study

INTRODUCTION: Patients' perception about their health condition, mainly involving chronic diseases, has been investigated in many studies and it has been associated to depression, compliance with the treatment, quality of life and prognosis. The Illness Effects Questionnaire (IEQ) is a tool which makes the standardized evaluation of patients' perception about their illness possible, so that it is brief and accessible to the different clinical settings. This work aims to begin the transcultural adaptation of the IEQ to Brazil through the validated translation and the reliability study. METHODS: The back-translation method and the test-retest reliability study were used in a sample of 30 adult patients under chronic hemodialysis. The reliability indexes were estimated using the Pearson, Spearman, Weighted Kappa and Cronbach's alpha coefficients. RESULTS: The semantic equivalence was reached through the validated translation. In this study, the reliability indexes obtained were respectively: 0.85 and 0.75 (p < 0.001); 0.68 and 0.92 (p < 0.0001). DISCUSSION: The reliability indexes obtained attest to the stability of responses in both evaluations. Additional procedures are necessary for the transcultural adaptation of the IEQ to be complete. CONCLUSION: The results indicate the translation validity and the reliability of the Brazilian version of the IEQ for the sample studied.
