Background Prostatic male genital schistosomiasis and prostate cancer co-existence cases are uncommon however, some studies have indicated that schistosomiasis may trigger development of prostate cancer regardless of age. Schistosomiasis is a public health problem in sub-Saharan Africa and may account for some undocumented cases of schistosomiasis prostatic cancer in schistosome endemic rural communities. It is against this background that we investigated the association between schistosomiasis and risk of prostate cancer development in residents of Murehwa Community, a schistosomiasis endemic area. Methodology We conducted a cross sectional study involving 366 men residing in Murehwa District, Zimbabwe. Schistosoma haematobium and S. mansoni infection was diagnosed using urine filtration and Kato Katz techniques, respectively. Haematuria was detected using urinalysis reagent strip test. A structured questionnaire was used to obtain history of schistosomiasis infection among study participants. Risk of prostate cancer development was assessed by measuring prostate-specific antigen levels in serum using the ELISA. Results Prevalence of S. haematobium and S. mansoni infection was 12.3% and 1.4%, respectively. Individuals with schistosomiasis had higher prostate-specific antigen levels (mean 1.208 ± SD 1.557 ng/mL) compared to those without schistosomiasis (mean 0.7721 ± SD 1.173 ng/mL; p < 0.05). Older individuals > 50 years had higher prostate specific antigen levels (mean 0.7212 ± SD 1.313 ng/mL) compared to individuals < 50 years old (mean 0.4159 ± SD 0.8622 ng/mL; p < 0.05). Prostate-specific antigen levels log10 (mean 0.2584 ± SD 0.2128 ng/mL) and were associated to S. haematobium infection intensity log10 (mean 1.121 ± SD 0.5371 eggs/10 mL), r(s) = − 0.3225, p < 0.05. There was a correlation between prostate-specific antigen levels log10 (mean 0.2246 ± SD 0.1858 ng/mL) and S. haematobium infection intensity log10 (mean 1.169 ± SD 0.5568 eggs/10 mL) among participants with a history of schistosomiasis infection (r(s) = − 0.3520; p < 0.05). There was no correlation between prostate-specific antigen levels of > 4 ng/mL (mean 5.324 ± SD1.568 ng/mL) and schistosome eggs log10 (mean 1.057 ± SD 0.6730 eggs/10 mL; p > 0.05). Conclusion Urogenital schistosome infections and history of schistosome infections were associated with prostate specific antigen levels, an indicator for risk of prostate cancer. Therefore, S. haematobium schistosome egg burden was associated with the risk of prostate cancer development in adult males residing in Murehwa District, Zimbabwe.

“…From each study participant, 3 samples of fecal material were collected every other day and, from each sample, 2 slides were prepared by the Kato-Katz method. Each slide was read by 2 different analysts, and a third analyst was consulted when the results of the first evaluators differed by more than 30% in the account of the number of eggs or in the detection of the presence of the infection 13 .…”

Introduction: Schistosomiasis, caused by infection from Schistosoma mansoni, is a disease that represents an important public health problem for Brazil, especially for states in the Northeast region. Thus, the aim of this study is to present a new epidemiological profile for the disease in a municipality with low prevalence in the state of Alagoas, Brazil. Methods: A cross-sectional study was conducted through a coproparasitological and malacological survey. A structured questionnaire was applied to the study participants to survey possible risk factors and a spatial analysis (kernel density) was used to measure the risk of infection. Results: Of the 347 participants, 106 (30.5%) were infected by Schistosoma mansoni, most of them from the urban area of the municipality (68.9%; 73/106). A 3-fold risk of infection was found for individuals living in the urban area and a risk of 2.15 times for self-declared farmers. Biomphalaria glabrata and B. straminea were the species found in the municipality, but no animals were diagnosed as infected by the parasite. Spatial analysis showed a random distribution of vectors and human cases of the disease, and the formation of two clusters of human cases in the urban area was seen. Conclusions: A new epidemiological profile for schistosomiasis from S. mansoni infection was presented in a municipality of low endemicity: a high proportion of positive individuals in the urban area; presence of snails without positive diagnosis for S. mansoni infection; random distribution of vectors and human cases; and absence of association between classical risk factors and human infection.

“…Así mismo, durante el primer semestre de la vigencia 2017, se aplicó el segundo instrumento, dirigido a población estudiantil en el nivel de educación media (grados decimo y undécimo); compuesto por 7 ítems de información personal, 19 ítems sobre el aprovechamiento del tiempo libre, 14 ítems de análisis reflexivo sobre los procesos de enseñanza aprendizaje y 11 ítems para identificar factores que inciden en la condición personal y emocional de los estudiantes. (Fuente propia, 2016;2017) Por otra parte, se realizó una segunda observación en una institución educativa del Municipio de Girardot, Departamento Cundinamarca; compuesta por una población aproximada de 2000 estudiantes, 58 docentes, 3 coordinadores, 1 psicóloga y 1 rector distribuidos en dos sedes de educación básica primaria y una sede principal de educación básica secundaria y media. En esta institución se realizaron dos tipos de análisis.…”
