Genetic variability of Blastocystis sp. isolated from symptomatic and asymptomatic individuals in Iran.

Abstract: Blastocystis is an unusual enteric protozoan parasite of humans and many animals whose pathogenic potential is still controversial. To increase the understanding of the molecular epidemiology of this emerging parasite and due to its potential impact on public health, its subtypes (STs) in Iranian symptomatic and asymptomatic individuals were determined. A total of 100 Blastocystis isolates by microscopy and culture methods were obtained. DNA was extracted from the positive culture isolates, and the Blastocystis subtypes were identified using seven subtype-specific sequenced-tagged site (STS) primers. Four subtypes, ST3 as dominant (53 %), followed by ST1 (48 %), ST5 (33 %), and ST2 (7 %) were identified. In this study, ST1 in gastrointestinal patients compared to asymptomatic individuals was significantly dominant (p = 0.001). From 33 (33 %) mixed subtype infections, ST1, 3 (14 %) was significantly related to GI symptoms (p = 0.045), and eight mixed infections with three different STs, which are under reported, were also identified.

Educational Interventions for Cervical Cancer Screening Behavior of Women: A Systematic Review

Abstract: Background: Cervical cancer is the second most common cancer in women worldwide; early detection can play a key role in reducing the associated morbidity. The objective of this study was to systematically assess the effects of educational interventions on cervical cancer screening (CCS) behavior of women. Methods: In this review the Cochrane library, Web of Science, Science Direct, PubMed, Scopus and search engine of Google scholar were searched for all interventional studies (trails, pre- and post-test or quasi-experimental) published in 2000-2017 for a systematic review, The search was based on the following keywords: cervix cancer, uterine cervical neoplasms, screening, prevention and control, Papanicolaou Test, pap test, pap smear, education, intervention, systematic review. Due to the heterogeneity of the data, a qualitative analysis was performed. Results: Thirty seven articles with 15,658 female participants in different parts of world were included in the review. About three quarters of the articles covered behavior change interventions. About one fourth of the articles were based on health education methods. The heath belief model is the most popular used framework for cervical cancer screening interventions. The results of our study showed that different health education methods (such as calls, mailed postcards, mother/daughter education. consultation sessions, picture books, videos, PowerPoint slides, small group discussions, educational brochures, radio broadcast education, lecture presentations, tailored counseling and a fact sheet, Self-learning package, face-to- face interviews and etc) are effective in modifying cervical cancer screening behavior of women. Conclusions: Our results showed that the different interventions and health behavior change frameworks provide an effective base for cervical cancer prevention. Heath providers can chose educational methods based on the particular client situations.
