A cross-sectional study on Trypanosoma cruzi was carried out in 2013 to evaluate the role of dogs as possible source of infection for humans in two rural communities of the highly endemic Bolivian Chaco (Bartolo, Chuquisaca Department, n = 57 dogs; and Ivamirapinta, Santa Cruz Department, n = 48 dogs). Giemsa-stained thick and thin smears, rapid immunochromatographic test (ICT) (Chagas Quick test, Cypress Diagnostic, Belgium) and polymerase chain reaction for T. cruzi on dried blood spots were performed. All smears proved negative by microscopic examination, whereas 23/103 (22%) were positive by ICT and 5/105 (5%) blood samples contained T. cruzi DNA, evidencing the potential role of dogs in the domestic transmission of the parasite.

These results highlight the need for the promotion of access to clean water, improved sanitation and better hygiene, thus reducing the frequency of preventive chemotherapy for STHs while continuing to monitor the population for possible recrudescence.
Prevalencia del burnout académico en estudiantes de medicina y su implicancia para la creación de un centro de apoyo psicológico
(2025) Sofía Angulo; H. Miranda; Patricia Rojas
Academic burnout is an increasing concern among students in highly demanding programs such as Medicine, as it negatively affects their emotional well-being and academic performance. This study aimed to assess burnout levels among students at the Universidad Nacional del Oriente (UNO) in Bolivia and to provide an evidence-based rationale for establishing a Psychological Support Center. A quantitative, descriptive, and cross-sectional design was employed, using the Maslach Burnout Inventory–Student Survey (MBI-SS) administered to a randomly selected sample of 165 students. Results showed that 80% of participants experienced high emotional exhaustion, 20% reported high cynicism, and only 14.5% maintained high academic efficacy. These findings indicate substantial psychological strain consistent with Maslach and Jackson’s theoretical framework. The study concludes that establishing a Psychological Support Center offering counseling, stress management workshops, and peer support groups is essential to prevent burnout, reduce academic dropout, and promote a healthier educational environment.
Seroprevalence of West Nile and dengue virus in the human population of the Bolivian Chaco
(Wiley, 2018) Alessandro Bartoloni; Maria Elena Remoli; Francesca Farchi; Lorenzo Zammarchi; Claudia Fortuna; Eleonora Benedetti; Maria Grazia Ciufolini; Fabio Macchioni; Patricia Rojas; Yunni Lara
To determine the seroprevalence of antibodies against dengue virus (DENV) and West Nile virus (WNV) in the human population of the Bolivian Chaco, we tested 256 inhabitants of two rural communities. The seroprevalence, confirmed by plaque reduction neutralization test, was 7.8% and 2.7% for DENV and WNV, respectively.

(Oxford University Press, 2004) William P. Mackay; Jean‐Michel Maes; Patricia Rojas; Gladys Luna
We provide a review of the North American ants (north of Colombia) of the ant genus Mycocepurus, including keys to the workers and females, illustrations and distribution maps. The distribution of M. tardus is extended to Nicaragua and Costa Rica. The female of M. curvispinosus is described.
