Dengue in Brazil and Colombia: a study of knowledge, attitudes, and practices

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic and vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results The surveys show knowledge of the vector, but little knowledge about diagnosis, prognosis, and treatment. Vector infestation indices show Brazil to have good relative control, while Colombia presents a high transmission risk. Conclusions Given the multidimensionality of dengue control, vertical control strategies are inadequate because they deny contextualized methods, alternative solutions, and local empowerment.

Cryptococcosis in Atlántico, Colombia: an approximation of the prevalence of this mycosis and the distribution of the etiological agent in the environment

ABSTRACTINTRODUCTION:Cryptococcosis is an invasive disease acquired by inhalation of infectious propagules from the environment. Currently, compulsory notification of the spread of this disease is not required in Colombia. However, reporting of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome cases to the National Surveillance System has suggested that there is a growing population at risk of contracting cryptococcosis. Few studies have described the occurrence of cryptococcosis in Colombia. Therefore, in this study, we examined the pathology of this disease in Atlántico, Colombia and determined the distributions of Cryptococcus neoformans and Cryptococcus gattii in the environment.METHODS:Clinical samples/isolates were gathered from cases of cryptococcosis previously diagnosed at health institutions in Atlántico, and surveys were completed by clinicians. The environmental study considered 32 sampling points and three tree species, i.e., Quickstick ( Gliricidia sepium ), Almond ( Terminalia catappa ), and Pink trumpet ( Tabebuia rosea ). Environmental and clinical samples/isolates were analyzed for phenotypic and genotypic confirmation.RESULTS:From 1997-2014, 41 cases of cryptococcosis were reported. The mean patient age was 40.5 years (range: 18-63 years); 76% were men, and 78% were HIV positive. Isolation was possible in 38 cases ( C. neoformans , molecular type VNI in 37 cases and C. gattii , molecular type VGI in one case). In 2012-2014, 2,068 environmental samples were analyzed with a positivity of 0.4% ( C. neoformans , molecular type VNI) in Almond and Pink trumpet trees.CONCLUSIONS:Cryptococcus neoformans , molecular type VNI had a higher prevalence than C. gattii and was associated with human exposure and the pathogenesis of cryptococcosis in this geographical region.

Qualidade de vida de professores do ensino fundamental: uma perspectiva para a promoção da saúde do trabalhador

A qualidade de vida é um importante aspecto a ser considerado na promoção de saúde dos professores, sobre os quais vêm sendo atribuídas diversas funções no cotidiano de suas atividades de trabalho. OBJETIVO: Avaliar a qualidade de vida dos professores do ensino fundamental do município de Jequié-BA. MÉTODO: A pesquisa foi realizada com uma amostra aleatória constituída por 91 professores que responderam o questionário genérico de avaliação da qualidade de vida (SF-36). O questionário analisa oito domínios relativos à qualidade de vida. Os dados foram analisados por meio da estatística descritiva, com determinação de médias, freqüências e desvio-padrão. RESULTADOS: Todos os domínios do SF-36 apresentaram-se prejudicados com destaque para vitalidade (46,26) e dor (53), como os de menor escore, e capacidade funcional (65,71) e limitação por aspectos emocionais (62,63), como os de maior escore. CONCLUSÃO: A qualidade de vida da população estudada encontra-se comprometida, o que pode repercutir no estado de saúde de tais indivíduos.

Custo anual do manejo da cardiopatia isquêmica crônica no Brasil: perspectiva pública e privada

OBJETIVO: Estimar o custo anual do manejo da doença arterial coronária (DAC) em valores do SUS e convênios. MÉTODOS: Estudo de coorte, incluindo pacientes ambulatoriais com DAC comprovada. Considerou-se para estimar custos diretos: consultas, exames, procedimentos, internações e medicamentos. Valores de consultas e exames foram obtidos da tabela SUS e da Lista de Procedimentos Médicos (LPM). Valores de eventos cardiovasculares foram obtidos de internações em hospital público e privado com estas classificações diagnósticas em 2002. O preço dos fármacos utilizado foi o de menor custo no mercado. RESULTADOS: Os 147 pacientes (65±12 anos, 63% homens, 69% hipertensos, 35% diabéticos e 59% com IAM prévio) tiveram acompanhamento médio de 24±8 meses. O custo anual médio estimado por paciente foi de R$ 2.733,00, pelo SUS, e R$ 6.788,00, para convênios. O gasto com medicamentos ($ 1.154,00) representou 80% e 55% dos custos ambulatoriais, e 41% e 17% dos gastos totais, pelo SUS e para convênios, respectivamente. A ocorrência de evento cardiovascular teve grande impacto (R$ 4.626,00 vs. R$ 1.312,00, pelo SUS, e R$ 13.453,00 vs. R$ 1.789,00, para convênios, p<0,01). CONCLUSÃO: O custo médio anual do manejo da DAC foi elevado, sendo o tratamento farmacológico o principal determinante dos custos públicos. Essas estimativas podem subsidiar análises econômicas nesta área, sendo úteis para nortear políticas de saúde pública.

Ecology of phlebotomine sand flies (Diptera: Psychodidae)in a focus of Leishmania (Viannia) brasiliensis in northeastern Colombia

The phlebotomine sand fly fauna of two coffee plantations in a Leishmania-endemic area of Norte de Santander, Colombia was studied. Regular insect collections using a variety of methods were made for three and a half years. Information was obtained on diurnal resting sites, host range and seasonal abundance for 17 species, of wich five (Lutzomyia spinicrassa, Lu. serrana,Lu. shannoni, Lu. ovallesi and Lu. gomezi) were far more numerous than the others, anthropophilic and present throughout the year. The behaviour of these and the remaining 12 species is discussed in relation to their potential role in transmission of Leishmania (Viannia) brasiliensis in the area.
