Serum BDNF, VEGF, and EGF Levels in Pregnant Women with Anxiety and Depression

Antenatal anxiety and depression frequently co-occur, negatively affecting maternal and offspring outcomes, yet their biological correlates remain insufficiently characterized. This cross-sectional study examined associations between anxiety and depressive symptoms and serum conc...

Susceptible perinatal windows to arsenic exposure and serum antibody levels in children

Several cohorts have documented potential immunotoxic effects of arsenic in pediatric populations, however, the identification of susceptible windows to arsenic exposure remains poorly investigated in relation to vaccine-specific antibody responses. The present study examines per...

Premature Coronary Artery Disease, Association with Relative Blood Number of Mitochondrial DNA Copies in Mexican Population—Results of GEA Study

The mitochondrial DNA copy number (mtDNA-CN) is considered an indirect indicator of the number of mitochondria and of mitochondrial dysfunction; its decrease may indirectly reflect mitochondrial DNA (mtDNA) alterations. A reduction in mtDNA-CN is associated with the development o...

Implementing milestone-based assessment to document surgical competence progression in an obstetrics and gynecology residency program: a mixed-methods study from Latin America

Competency-based medical education emphasizes outcomes and developmental progression, yet traditional numeric evaluations often fail to capture changes in surgical competence over time. Surgical milestones offer a structured framework for formative assessment, but their adaptatio...

A network-driven antiviral discovery pipeline for emerging RNA viruses: a critical perspective from the Red Mexicana de Desarrollo de Antivirales (RMDA)

INTRODUCTION: RNA viruses impose a disproportionate burden of emerging and reemerging infectious diseases in Latin America, yet antiviral discovery in the region remains fragmented, target-limited, and frequently disconnected from translational pathways. This perspective discusse...
