IntroducciÓn: la pandemia de la COVID-19 ha acentuado las desigualdades sociales, económicas y relacionadas con la salud, afectando desproporcionadamente a las personas en situación de vulnerabilidad y perpetuando la inequidad en salud. En Argentina se implementó una campaña nacional gratuita de vacunación contra la COVID-19 con una perspectiva de equidad.

Objetivo: identificar desigualdades territoriales en el acceso a la vacunación contra la COVID-19 en Quilmes.

The objective was to estimate the health impact of the total ban on advertising of tobacco products in terms of avoided cardiovascular events in those over 35 years of age in Argentina.The Cardiovascular Disease Policy Model (CVDPM) was used, which is a Markov simulation model used to represent and project mortality and morbidity due to cardiovascular disease (CVD) in the population aged 35 or over. It constitutes a demographic-epidemiological model, which represents the population between 35 and 95 years of age and uses a logistic regression model based on the Framingham equation to estimate the annual incidence of cardiovascular disease.

Objective: To measure SARS-CoV-2 RNA in sewage in a low-resource community in order to determine if it can be considered as an estimator of changes in the prevalence of COVID-19 in the population.

Methods: In this descriptive observational study we collected samples of surface waters contaminated with sewage and optimized a method of purification of viral RNA using PEG concentration. We determined the amount of genetic material by quantitative real-time PCR using the CDC method for SARS-CoV-2 detection.

Background: Sugar-sweetened beverage (SSB) consumption is associated with obesity, diabetes, and hypertension. Argentina is one of the major consumers of SSBs per capita worldwide. Determining the impact of SSB reduction on health will inform policy debates.

Cardiovascular disease (CVD) is the leading cause of death in Argentina. Computer simulation models allow to extrapolate evidence to broader populations than the originally studied, over longer timeframes, and to compare different subpopulations. The Cardiovascular Disease Policy Model (CVDPM) is a computer simulation state transition model used to represent and project future CVD mortality and morbidity in the population 35 years-old and older.

Objective:: To describe the population that reports to have visited tobacco points of sale (POS) in Argentina and their perception of tobacco advertising.

Materials And Methods:: We used data from the 2013 National Risk Factor Survey.

Results:: We included 31 167 respondents (96% of the total) who attended a store that sells cigarettes in the previous 30 days.

Introduction: In Argentina, the national guidelines for lipid control emphasize the use of relatively inexpensive low- or moderate-potency statins by patients at high risk (>20 %) of a cardiovascular event. The objective of this study was to compare the impact and costs of the current national CVD prevention guidelines with regard to morbidity and mortality in Argentina with the impact and costs of three strategies that incorporate high-potency statins.

Methods: We used the CVD Policy Model-Argentina to model the proposed interventions.

Tobacco use is the leading preventable cause of deaths worldwide. The MPOWER package, the six recommended policies of the World Health Organization (WHO) to reverse the tobacco epidemic, strongly recommends monitoring tobacco use trends. Because evidence indicates that smoking addiction often starts before the age of 18 years, there is a need to monitor tobacco use among youths.

Background: Cardiovascular disease (CVD) is the leading cause of death in adults in Argentina. Sodium reduction policies targeting processed foods were implemented in 2011 in Argentina, but the impact has not been evaluated. The aims of this study are to use Argentina-specific data on sodium excretion and project the impact of Argentina's sodium reduction policies under two scenarios - the 2-year intervention currently being undertaken or a more persistent 10 year sodium reduction strategy.

Objective: To identify main barriers to preventing cardiovascular disease and implementing clinical practice guidelines in primary care, to pilot implementation of a tailored enactment of the adapted World Health Organization guidelines to prevent cardiovascular disease, and to assess the impact of the intervention in risk stratification.

Methods: A qualitative study was done with decision makers, health professionals, and staff from five primary health care centers, who were interviewed to identify the main barriers. A tailored intervention to apply the guidelines was then designed and implemented.

Objective: Estimate the cost-utility ratio of an intervention to reduce dietary salt intake in people over the age of 35 in Argentina.

Methods: The intervention consisted of reducing salt content in food by 5% to 25%. A simulation model was used to measure the impact of policies on heart disease in order to predict incidence, prevalence, mortality, and cost trends for heart and cerebrovascular disease in the population aged 35 - 84.

Background: Argentina's congress passed a tobacco control law that would enforce 100% smoke-free environments for the entire country, strong and pictorial health warnings on tobacco products and a comprehensive advertising ban. However, the Executive Branch continues to review the law and it has not been fully implemented. Our objective was to project the potential impact of full implementation of this tobacco control legislation on cardiovascular disease.

Background: Chagas disease affects mainly poor populations in Latin America. This review assesses the evidence on the independent risk of cardiovascular events associated with positive Chagas serology.

Methods: We searched for studies using the following outcomes: death, stroke, new onset heart failure, heart failure hospitalization or evidence of left ventricular dysfunction.

Objectives: To evaluate how socio-economic gradients in NCDs and NCD-related risk factors change over time.

Methods: Secondary analysis of cross-sectional data from the 2005 and 2009 Argentine National Risk Factor Surveys (N = 41,392 and N = 34,732) was conducted. We analyzed inequalities in three risk factors (low physical activity, obesity, and diabetes) according to income and educational attainment.

Health literacy in patients attending a University Hospital. Low level of health literacy is associated with poor communication between patients and clinicians and with increased hospitalization rates, less frequent screening for cancer, poor control of diabetes, and disproportionately high rates of disease and mortality. Despite the importance of health literacy in medicine, there is no information about its prevalence in Latin America.
