[Public policies and interventions to prevent excess weight in Mexico: analysis from an intersectional perspective].

The scope of this article is to analyze public policies and interventions (PPI) prevailing in 2022 at the national level for the prevention of excess weight (overweight and obesity) in the adult population of Mexico, from an intersectional perspective. We performed documental analysis of PPI to prevent excess weight in Mexico in adulthood by applying a methodology for policy analysis based on intersectionality (Intersectionality-Based Policy Analysis Framework). A total of nine PPI were analyzed.

High-dimensional analysis of 16 SARS-CoV-2 vaccine combinations reveals lymphocyte signatures correlating with immunogenicity.

The range of vaccines developed against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) provides a unique opportunity to study immunization across different platforms. In a single-center cohort, we analyzed the humoral and cellular immune compartments following five coronavirus disease 2019 (COVID-19) vaccines spanning three technologies (adenoviral, mRNA and inactivated virus) administered in 16 combinations. For adenoviral and inactivated-virus vaccines, heterologous combinations were generally more immunogenic compared to homologous regimens.

[A population-based study on seroprevalence and factors associated with SARS-CoV-2 infection in Córdoba, Argentina].

Seroepidemiological studies help identify the indirect distribution of diseases, detecting serological markers of immunity and demonstrating undiagnosed infections in the general population. The objectives were to estimate the seroprevalence of SARS-CoV-2 antibodies in Córdoba, Argentina, from December 2020 to January 2021 and to identify factors associated with the virus' contagiousness. A population-based cross-sectional observational study was performed in 3,225 individuals over two years of age living in Córdoba city, selected by multiple-stage random sampling proportional to distribution by gender, age group, and socioeconomic status in the city's population.

[Vaccination against SARS-CoV-2 and its relationship with illness and death from COVID-19 in ArgentinaVacinação contra SARS-CoV-2 e sua relação com doença e morte por COVID-19 na Argentina].

Objective: To determine the effectiveness of vaccination against SARS-CoV-2 in preventing illness and death from COVID-19 in Córdoba, Argentina, during the period from January through June 2021.

Methods: A retrospective cohort study was conducted among 1,139,458 residents of the province of Córdoba. Multiple logistic regression models were developed to describe the relationship between vaccination and the presence of SARS-CoV-2 or death from COVID-19, while taking account of comorbidities and chronic disease risk factors and adjusting for sex and age.
