“…A esquistossomose é uma doença infecciosa de caráter endêmico, associada à pobreza e ao baixo desenvolvimento econômico, encontrada em 54 países da África, Ásia e América do Sul. Estima-se que, no Brasil, mais de 200 milhões de pessoas estejam infectadas, e que outras 779 milhões correm o risco de infecção pelo S. mansoni em todo o mundo 7 .…”

Objetivo: Avaliar a frequência de helmintos a partir dos dados do Programa de Controle de Esquistossomose no município do Xexéu-PE. Métodos: Por meio de estudo descritivo e transversal de abordagem quantitativa, tendo, por base, 3031 resultados de exames parasitológicos de fezes do período de 2013 a 2015. Resultados: Verificou-se que 15,73% das amostras estavam positivas para algum tipo de parasitos, sendo observada maior frequência no sexo feminino, com percentual de 54,71%, além de ser observado que a faixa etária mais acometida foi a de 12 a 18 anos (24,73%). No levantamento do grau de parasitismo, houve maior positividade de humanos monoparasitados (80,92%), sendo o helminto S. mansoni (44,86%), o mais evidenciado. Conclusão: É necessária a utilização de atividades educacionais pertencentes à higiene, medidas profiláticas, que devem ser tomadas para minimizar esse problema na saúde pública.

Background:We analyzed the trends and spatial patterns of schistosomiasis-related mortality in Northeast Brazil in 2000-2019.Methods: A mixed population-based ecological study was conducted, using information on the underlying or associated causes of death. We used Joinpoint regression analysis to calculate the trends. The spatial analysis included rates, spatial moving averages, and standardized mortality rates. The spatial dependence analysis was based on Getis-Ord's G and Gi* indices (Gi star) and local Moran's index to check for autocorrelation.Results: A total of 5,814,268 deaths were recorded, of which 9,276 (0.16%) were schistosomiasis-related; 51.0% (n=4,732, adjusted rate 0.90/100,000 inhabitants [95% confidence interval (CI) 0.88-0.93]) were males; 40.0% (n=3,715, adjusted rate 7.40/100.000 inhabitants [95%CI: 7.16-7.64]) were ≥70 years old; 54.8% (n=5,087, crude rate 0.80/100,000 inhabitants) were of mixed/Pardo-Brazilian ethnicity; and 77.9% (n=7,229, adjusted rate 0.86/100,000 inhabitants [95%CI: 0.84-0.88]) lived outside state capitals. The highest proportion of deaths was in the state of Pernambuco (53.9%, n=4,996, adjusted rate 2.72/100,000 inhabitants [95%CI: 2.64-2.79]). Increasing mortality rate was verified in the state of Sergipe. On the coast of the state of Rio Grande do Norte and Bahia, there was spatial dependence of spatio-temporal risk patterns with clusters. Throughout the study period, we found positive spatial autocorrelation and cluster formation. Conclusions:In Northeast Brazil, schistosomiasis persists with a high mortality rate, especially in the coastal region, with heterogeneous spatial and temporal patterns. To eliminate schistosomiasis by 2030, it is necessary to strengthen the financing and management of the unified health system (SUS).

The present work aimed to evaluate in vitro the molluscicidal activity and latex toxicity of Euphorbia milii var. splendens (Bojer ex Hook) Ursch & Leandri for the control of mollusks of the species Biomphalaria tenagophila. Specimens of E. milii var. splendens cultivated in the rural region of Pindamonhangaba were selected, from which latex was obtained by the transverse incision of the aerial parts. For the molluscicide test, adult mollusks of the species B. tenagophila were separated into groups of 10 and submitted to latex immersion at concentrations of 2.5 ppm, 1.25 ppm, 0.625 ppm, and 0.3125 ppm for 24 hours. In parallel, the toxicity of latex at a concentration of 0.3125 ppm was determined by testing with Artemia salina (mortality assessment) and using the Allium cepa test (determination of growth inhibition, amount, and weight of roots). It was observed an important molluscicidal activity of E. milii var. splendens latex at the various concentrations evaluated. In addition, it was also possible to observe moderate toxicity against A. salina nauplii and in the toxicity test with A. cepa. This demonstrates the potential of using latex from E. milii var. splendens to control populations of B. tenagophila species, not only for the observed molluscicidal activity but also for the moderate mortality of A. salina nauplii, whereas in the A. cepa test no change was observed in the parameters evaluated in relation to the control group, demonstrating safety for use in the environment.
