Effects of Selenium treatment on cardiac function in Chagas heart disease: Results from the STCC randomized Trialby Marcelo T. Holanda et al.
Se treatment did not improve cardiac function (evaluated from LVEF) in CCC. However, in the subgroup of patients at B2 stage, a potential beneficial influence of Se was observed. Complementary studies are necessary to explore diverse Se dose and/or associations in different CCC stages (B2 and C), as well as in A and B1 stages with longer follow-up.
Epidemiology, Biodiversity, and Technological Trajectories in the Brazilian Amazon: From Malaria to COVID-19by Claudia Codeço et al.
The Amazon biome is under severe threat due to increasing deforestation rates and loss of biodiversity and ecosystem services while sustaining a high burden of neglected tropical diseases. Approximately two thirds of this biome are located within Brazilian territory. There, socio-economic and environmental landscape transformations are linked to the regional agrarian economy dynamics, which has developed into six techno-productive trajectories (TTs).
In current times, it’s easy to forget that over 70% of deaths worldwide are due to non-communicable diseases. How can we tackle their rise? The theory of epidemiological transition (or the changing patterns of population age distributions, mortality, fertility, life expectancy, and causes of death) offers a valuable framework for understanding how different types of diseases can occur simultaneously in a population.
Emerging complexities and rising omission: Contrasts among socio-ecological contexts of infectious diseases, research and policy in Brazilby Leandro Giatti et al.
In this article, we explore elements that highlight the interdependent nature of demands for knowledge production and decision-making related to the appearance of emerging diseases. To this end, we refer to scientific production and current contextual evidence to verify situations mainly related to the Brazilian Amazon, which suffers systematic disturbances and is characterized as a possible source of pathogenic microorganisms.
