A systematic review and meta-analysis of the prevalence of Leishmania infection in blood donors.

Background: The risk of transfusion transmitted leishmaniasis (TTL) from apparently healthy persons or asymptomatic individuals, should not be ignored. Lack of a comprehensive review, encouraged us to design a systematic review with meta-analysis approach to assess the prevalence of Leishmania infection in healthy blood donors.

Methods: For this purpose, 6 English databases (PubMed, Scopus, Web of Sciences, Science Direct, EMBASE and CINAHL) were browsed from January 1990 to July 2016.

Toxoplasmosis in rodents: A systematic review and meta-analysis in Iran.

During recent years, implication of rodents in the epidemiology of Toxoplasma gondii is overlooked in Iran; thus, we performed a systematic review and meta-analysis to evaluate the prevalence of toxoplasmosis in rodents of Iran. For this purpose, following the general methodology recommended for systematic reviews and meta-analysis, 5 English and 3 Persian databases were explored from 1 January 2000 till 10 September 2016 using related keywords. Finally, 9 out of 291 citations were met to be included in this study.
