RESUMEN
The retraction of health sciences publications is a growing concern. To understand the patterns in a particular country-context and design specific measures to address the problem, it is important to describe and characterize retractions. We aimed to assess the evolution of health science retractions in Brazil and Portugal and to describe their features. We conducted a cross-sectional study including all health sciences retracted articles with at least one author affiliated to a Portuguese or Brazilian institution identified through Retraction Watch database. A total of 182 retracted articles were identified. The number of retractions increased over time, but the proportion related to the whole of publications remained stable. A total of 50.0% and 60.8% of the Portuguese and Brazilian retracted articles, respectively, were published in first and second quartile journals. Scientific misconduct accounted for 60.1% and 55.9% of retractions in Brazil and Portugal. In both countries, the most frequent cause of misconduct was plagiarism. The time from publication to retraction decreases as the journal quartile increases. The retraction of health sciences articles did not decrease over time in Brazil and Portugal. There is a need to develop strategies aimed at preventing, monitoring and managing scientific misconduct according to the country context.

BACKGROUND: Dating from the 1920s and linked to the increase in mortality among smokers, tobacco has become one of the most studied health risk factors. Tobacco-use series, whether for the general population or for specific groups, are unavailable for most South American countries, something that hinders the characterisation of this risk factor. OBJECTIVES: To identify and analyse studies that estimate smoking-attributable mortality (SAM) in South America and provide an overview of the impact of smoking habit on mortality in the region. METHODS: Systematic review using PubMed, Embase, LILACS, Biblioteca Virtual en Salud, Google Scholar and Google, and including all papers published until June 2020 reporting studies in which SAM was estimated. RESULTS: The search yielded 140 papers, 17 of which fulfilled the inclusion criteria. There were SAM estimates for all South American countries, with Argentina having the most. The first estimate covered 1981 and the latest, 2013. The method most used was prevalence-based. Regardless of the country and point in time covered by the estimate, the highest figures were recorded for men in all cases. The burden of attributable vs observed mortality varied among countries, reaching a figure of 20.3% in Argentina in 1986. The highest SAM burden was registered for the group of cardiovascular diseases. CONCLUSIONS: SAM estimates are available for all South American countries but the respective study periods differ and the frequency of the estimates is unclear. For 4 countries, the only estimates available are drawn from reports, something that does not allow for a detailed assessment of the estimates obtained. To help with decision-making targeted at evaluating and enhancing the impact of smoking control policies, further studies are needed in order to update the impact of smoking on all countries across South America.

RESUMEN: Objetivo: Actualizar la estimación de la mortalidad atribuida al consumo de tabaco en Brasil en población de 35 y más años. Métodos: Se aplicó un método dependiente de prevalencia, basado en la fracción atribuida poblacional. Este método estima la mortalidad atribuida a partir de la mortalidad observada en Brasil (fuente: Sistema de Información de Mortalidad del Sistema Único de Salud de Brasil-2016); de las prevalencias de fumadores, exfumadores y nunca fumadores (Encuesta Nacional de Salud de Brasil-2013) y del exceso de riesgo de morir (riesgo relativo) que tienen los fumadores y exfumadores en comparación con los nunca fumadores (5 estudios de cohortes norteamericanos). Se presentan estimaciones de mortalidad atribuida globales, por sexo, grupo de edad (35-54; 55-64; 65-74 y 75 años en adelante) y 3 grupos de enfermedades: tumores malignos, enfermedades cardiometabólicas y respiratorias. Resultados: En 2016, el consumo de tabaco causó con 163.831 muertes en Brasil, el 67% (109.369) fue en hombres y cuatro de cada diez (62.791) sucedieron antes de los 65 años. El 42% de la mortalidad atribuida se asocia a enfermedades cardiometabólicas, seguidas de respiratorias (34%) y tumorales (24%), sin diferencias por sexo. Conclusión: El 14% de las muertes que sucedieron en Brasil durante 2016 en población de 35 y más años se atribuye al consumo de tabaco. Realizar de forma periódica estimaciones de MA es necesario para valorar y fortalecer las leyes de control de tabaquismo implantadas.
ABSTRACT: Objective: To update the estimation of tobacco attributable mortality (AM) in the Brazilian population aged 35 years old and older. Methods: A prevalence-dependent analysis was applied based on the population attributed fraction. This method estimates the tobacco AM taking into account the mortality observed in Brazil (source: Brazilian Mortality Information System - 2016); the prevalence of smokers, former smokers, and never smokers (National Health Survey Brazil - 2013) and the excess of risk of death (relative risk) of smokers and former smokers in comparison to never smokers (derived from 5 North American cohorts). Estimates of overall AM are shown by gender, age group (35-54; 55-64; 65-74; and 75 years old and older) and 3 groups: malignant tumors, cardiometabolic diseases, and respiratory diseases. Results: In 2016, tobacco consumption caused 163,831 deaths in Brazil, 67% (109,369) were in men and four out of ten (62,791) occurred before the age of 65. Without differences by gender, 42% of the AM is associated with cardiometabolic diseases, followed by respiratory diseases (34%) and malignant tumors (24%). Conclusion: During 2016, 14% of the deaths occurred in the Brazilian population aged 35 years old and older were attributed to tobacco consumption. Periodic tobacco AM estimations are mandatory to assess and strengthen smoking control strategies and policies.
