Objective: To estimate the prevalence of self-reported tuberculosis TB diagnosed at Peruvian correctional facilities (CFs), and their associated factors. Methods: Cross-sectional study based on secondary analysis of the National Census held in all Peruvian CFs in 2016. Outcome was defined as self-reported TB diagnosed by a healthcare professional intra-penitentiary. A descriptive bivariate analysis was carried out, followed by multivariate analysis using Poisson regression in order to calculate the adjusted prevalence ratios (PRa). Additionally, a mixed effects multilevel model adjusted by CFs as clusters was performed. Results: Of 77 086 prison inmates in 66 CFs participated in the original census, of which 69 890 were included. Of these, 1754 self-reported TB diagnosed intra-penitentiary, yielding a prevalence of 2510/100 000 PDL. In the final model, self-reported TB was associated wit...

Objective: To study the antioxidant activity and phytochemical screening of capitula of Tagetes filifolia Lag. “pacha anís”. Materials and methods: An experimental study which used 5 kg of capitula of a medicinal plant called Tagetes filifolia Lag. collected from the Department of Junín, Peru. The phytochemical screening method proposed by Olga Lock, M.D. was used for the phytochemical screening and the DPPH method for the determination of the antioxidant activity. The sample was divided into 3 groups: ether, ethyl alcohol and distilled water at concentrations of 100, 50 and 5 μg/ml, respectively. Results: Abundant amounts of phenols were found in both the distilled water extract and the ethyl alcohol extract, and the latter had moderate amounts of quinones. Besides, the ethyl alcohol extract showed the largest percentage of freeradical scavenging (91.26%) at a concentration of 10...
