Article Abstract
The aim of the present study was to analyze IL6 rs1800795 genetic variant in the susceptibility to Trypanosoma cruzi infection and in the development of chronic Chagas cardiomyopathy (CCC), in five independent Latin American cohorts. A total of 3,087 individuals from Latin American countries (Argentina, Bolivia, Peru, and two cohorts from Colombia) were studied. In all cohorts, patients were classified as seropositive for T. cruzi antigens (n= 1,963) and seronegative (n= 1,124). Based on clinical evaluation, the seropositive patients, were classified as CCC (n= 900) and asymptomatic (n= 1,063). No statistically significant differences in the frequency of IL6 rs1800795 between seropositive and seronegative, or between CCC and asymptomatic patients, were found. Furthermore, after the meta-analysis no statistically significant differences were observed. Our results do not support a contribution of IL6 rs1800795 genetic variant in the susceptibility to the infection and the development of chronic Chagas cardiomyopathy in the studied populations.

To understand shared and ancestry-specific genetic control of brain protein expression and its ramifications for disease, we mapped protein quantitative trait loci (pQTLs) in 1,362 brain proteomes from African American, Hispanic/Latin American and non-Hispanic white donors. Among the pQTLs that multiancestry fine-mapping MESuSiE confidently assigned as putative causal pQTLs in a specific population, most were shared across the three studied populations and are referred to as multiancestry causal pQTLs. These multiancestry causal pQTLs were enriched for exonic and promoter regions.

Latin American women, girls, and LGBTQ+ (lesbian, gay, bisexual, transgender, and queer) individuals experience high rates of violence, making Latin America one of the world's most affected regions for gender-based violence. Television, a powerful socialization tool, shapes attitudes and influences behavior. This study analyzes 50 episodes from nine Spanish-language TV series set in Latin America, finding that 90% of episodes depict gender-based violence.

Rheumatoid arthritis (RA) is a chronic autoimmune disease in which dysregulated interferon regulatory factor 5 (IRF5) may amplify pro-inflammatory pathways; prior genetic studies of IRF5 single-nucleotide variants (SNVs) in RA are inconsistent across populations and have not included mestizo Mexicans or evaluated rs59110799 in RA. We aimed to test whether four IRF5 SNVs (rs2004640G/T, rs2070197T/C, rs10954213G/A, rs59110799G/T) confer susceptibility to RA in women from Central Mexico. In a case-control study of 239 women with RA and 231 female controls (all self-identified Mexican-Mestizos, ≥3 generations), genotyping was performed by real-time PCR with TaqMan® probes; 80% of samples were duplicated (100% concordance) and control genotypes conformed to Hardy-Weinberg equilibrium.

Objective: Androgens have been prescribed to alleviate symptoms in midlife women, but evidence regarding benefits and risks remains limited, with no clearly established indications for Testosterone therapy. In many Latin American countries, Testosterone is prescribed without specific guidelines, making it difficult to identify patients who might benefit. This position statement aims to summarize evidence and provide a Latin American perspective on androgen therapy in midlife and older women.
