Chagas disease is caused by the protozoan parasite . It is endemic in South and Central America and recently has been found in other parts of the world, due to migration of chronically infected patients. The current treatment for Chagas disease is not satisfactory, and there is a need for new treatments. In this work, we describe the optimization of a hit compound resulting from the phenotypic screen of a library of compounds against . The compound series was optimized to the level where it had satisfactory pharmacokinetics to allow an efficacy study in a mouse model of Chagas disease. We were able to demonstrate efficacy in this model, although further work is required to improve the potency and selectivity of this series.

Purpose: Epidemiologic studies suggest that the transgender population has a higher burden of cardiovascular (CV) disease. We aimed to assess CV risk and investigate the relationship between estradiol (E2) or ethinylestradiol (EE) use and carotid intima media thickness (cIMT) in transgender women.
Methods: This is a cross-sectional analysis nested into a transgender-specific cohort in Rio de Janeiro, Brazil, from August 2015 to February 2018.

Malaria, a parasitic disease caused by Plasmodium spp. and transmitted by Anopheles mosquitoes, remains a major global health issue, with an estimated 249 million cases and 608,000 deaths in 2022. Rapid and accurate diagnosis and treatment are crucial for malaria control and elimination.

Most triatomine bugs inhabit nests and shelters of vertebrates, some of which are closely associated with palm trees. A few species occupy domestic and peridomestic habitats, posing a threat to human health as natural transmitters of Chagas disease. A peridomestic specimen that yielded positive results for Trypanosoma cruzi in both microscope and polymerase chain reaction tests was collected during a vector control survey in northeastern Paraguay.

Background And Objective: Serological screening for Chagas disease (CD) in Latin American adults living in Europe is a cost-effective strategy for transmission prevention. The World Health Organization recommends two different serological tests including native and recombinant antigens for IgG detection. In Spain, most commercialized native tests require manual processing.

Chagas disease is one of the most important vector-borne diseases in Mexico. Triatoma pallidipennis (Stål) is one of the most epidemiologically important vector species. Despite being classified as a single species, various studies (molecular, morphometric, and biological) on populations across its distribution suggested it is composed of a group of cryptic species.
