Leishmania chagasi in opossums (Didelphis albiventris) in an urban area endemic for Visceral Leishmaniasis, Campo Grande, Mato Grosso do Sul, Brazil

We investigated the occurrence of Leishmania infantum chagasi in Didelphis albiventris opossums at a wild animal rehabilitation center in the city of Campo Grande, Brazil. A total of 54 opossums were tested for L. i. chagasi infection in peripheral blood and bone marrow samples. The samples were analyzed by direct examination, culturing in a specific medium, and polymerase chain reaction–restriction fragment length polymorphism. Leishmania i. chagasi DNA was detected by polymerase chain reaction–restriction fragment length polymorphism in 11 (20.37%) animals. A total of 81.81% of positive opossums were captured in areas of known visceral leishmaniasis transmission. These results suggest a role for D. albiventris in the urban transmission of visceral leishmaniasis

Self-Enhancement and Psychological Adjustment: A Meta-Analytic Review

This article advances the debate about costs and benefits of self-enhancement (the tendency to maintain unrealistically positive self-views) with a comprehensive meta-analytic review (299 samples, N = 126,916). The review considers relations between self-enhancement and personal adjustment (life satisfaction, positive affect, negative affect, depression), and between self-enhancement and interpersonal adjustment (informant reports of domain-general social valuation, agency, communion). Self-enhancement was positively related to personal adjustment, and this relation was robust across sex, age, cohort, and culture. Important from a causal perspective, self-enhancement had a positive longitudinal effect on personal adjustment. The relation between self-enhancement and interpersonal adjustment was nuanced. Self-enhancement was positively related to domain-general social valuation at 0, but not long, acquaintance. Communal self-enhancement was positively linked to informant judgments of communion, whereas agentic self-enhancement was linked positively to agency but negatively to communion. Overall, the results suggest that self-enhancement is beneficial for personal adjustment but a mixed blessing for interpersonal adjustment

Psychological well-being in Europe after the outbreak of war in Ukraine

: The Russian invasion of Ukraine on February 24, 2022, has had devastating effects on the Ukrainian population and the global economy, environment, and political order. However, little is known about the psychological states surrounding the outbreak of war, particularly the mental well-being of individuals outside Ukraine. Here, we present a longitudinal experience-sampling study of a convenience sample from 17 European countries (total participants = 1,341, total assessments = 44,894, countries with >100 participants = 5) that allows us to track well-being levels across countries during the weeks surrounding the outbreak of war. Our data show a significant decline in well-being on the day of the Russian invasion. Recovery over the following weeks was associated with an individual's personality but was not statistically significantly associated with their age, gender, subjective social status, and political orientation. In general, well-being was lower on days when the war was more salient on social media. Our results demonstrate the need to consider the psychological implications of the Russo-Ukrainian war next to its humanitarian, economic, and ecological consequences
