Bitcoin is part of the so-called crypto-currencies and can be defined as a universal decentralized public electronic payment system based on Blockchain technology. The problem it faces is trust in its use; therefore, the objective of this research is to analyze the factors that influence the adoption and use of Bitcoin in Mexico. For this purpose, the UTAUT2 model integrated with the trust variable, is used. The model was empirically tested by applying a survey of 106 questionnaires, under the partial least square’s method, with structural equation models (PLS-SEM). The main results indicate that performance expectation, hedonistic motivation, habit, and its decentralization; are the main factors that influence confidence for the adoption and use of Bitcoin. The results illustrate to companies and any interested party the advantages of using Bitcoin. [ABSTRACT FROM AUTHOR]

The epidemiology of Toxoplasma gondii infection in pregnant women in rural Mexico is largely unknown. The seroepidemiology of T. gondii infection in 439 pregnant women from 9 communities in rural Durango State, Mexico was investigated. Using commercial enzyme-linked immunoassays, sera were tested for T. gondii IgG, IgM, and avidity antibodies. Prevalences of T. gondii IgG antibodies in the communities varied from 0% to 20%. Overall, 36 (8.2%) of the 439 women had IgG T. gondii antibodies. Ten (2.3%) women had also T. gondii IgM antibodies; IgG avidity was high in all IgM-positive women, suggesting chronic infection. None of the women, however, had delivered a known T. gondii-infected child. The seroprevalence was significantly higher (P < 0.05) in women from low socio-economic conditions (14%) than in those with higher socio-economic status (6.6%). Multivariate analysis showed that T. gondii infection was associated with soil floors at home (adjusted OR = 2.89; 95% CI: 1.12-7.49). This is the first epidemiological study of T. gondii infection in pregnant women in rural Mexico. [ABSTRACT FROM AUTHOR]
