A prevalência do tabagismo no Brasil reduziu sobremaneira nas últimas décadas, mas o país ainda tem uma elevada carga de doença associada a este fator de risco. O objetivo deste trabalho foi estimar a carga de mortalidade, morbidade e custos para a sociedade associada ao tabagismo em 2015 e o potencial impacto gerado em desfechos de saúde e para a economia a partir do aumento de preços dos cigarros por meio de impostos. Foram desenvolvidos dois modelos: o primeiro é um modelo matemático baseado em uma microssimulação probabilística de milhares de indivíduos usando-se coortes hipotéticas que considerou a história natural, custos e a qualidade de vida destes indivíduos. O segundo é um modelo de impostos aplicado para estimar o benefício econômico e em desfechos de saúde de diferentes cenários de aumento de preços em 10 anos. O tabagismo foi responsável por 156.337 mortes, 4,2 milhões de anos de vida perdidos, 229.071 infartos agudos do miocárdio, 59.509 acidentes vasculares cerebrais e 77.500 diagnósticos de câncer. O custo total foi de R$ 56,9 bilhões, dos quais 70% corresponderam ao custo direto associado à assistência à saúde e o restante ao custo indireto devido à perda de produtividade por morte prematura e incapacidade. Um aumento de 50% do preço do cigarro evitaria 136.482 mortes, 507.451 casos de doenças cardiovasculares, 64.382 de casos de câncer e 100.365 acidentes vasculares cerebrais. O benefício econômico estimado seria de R$ 97,9 bilhões. Concluiu-se que a carga da doença e econômica associada ao tabagismo é elevada no Brasil e o aumento de impostos é capaz de evitar mortes, adoecimento e custos para a sociedade.

Objective To determine the effectiveness and degree of implementation of interventions for the control of Aedes aegypti in Latin America and the Caribbean (LAC) as reported in scientific literature. Methods We searched MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS, for experimental and observational studies, economic assessments and qualitative experiences carried out in LAC from 2000 to 2016. We assessed incidence and morbimortality of Aedes aegypti‐related diseases and entomological indices: Breteau (containers), House, and Pupae per Person. We used GRADE methodology for assessing quality of evidence. Results Of 1826 records retrieved, 75 were included and 9 cluster randomised clinical trials could be meta‐analysed. We did not identify any intervention supported by a high certainty of evidence. In consistency with qualitative evidence, health education and community engagement probably reduces the entomological indices, as do the use of insecticide‐treated materials, indoor residual spraying and the management of containers. There is low certainty of evidence supporting the use of ovitraps or larvitraps, and the integrated epidemiological surveillance strategy to improve indices and reduce the incidence of dengue. The reported degree of implementation of these vector control interventions was variable and most did not extend to whole cities and were not sustained beyond 2 years. Conclusions We found a general lack of evidence on effectiveness of vector control in the region, despite a few interventions that showed moderate to low certainty of evidence. It is important to engage and educate the community, apart from achieving the implementation of integrated actions between the health and other sectors at national and regional level.

ObjectiveOverweight and obesity are important contributors to the non-communicable disease burden. The consumption of sugar-sweetened beverages (SSBs) has been associated with an increased risk of type 2 diabetes mellitus (T2DM), cardiovascular disease, cancer and other conditions. The objective of this study was to estimate the burden of disease attributable to the consumption of SSBs and the costs to the healthcare systems in Argentina, Brazil, El Salvador, and Trinidad and Tobago.DesignFollowing a systematic review of models, a comparative risk assessment framework was developed to estimate the health and economic impact associated with the consumption of SSBs.SettingArgentina, Brazil, El Salvador, and Trinidad and Tobago.ParticipantsOverall population.Primary and secondary outcome measuresThe model estimated the effects of SSB consumption on health through two causal pathways: one mediated by body mass index (BMI) and health conditions associated with BMI and another that reflected the independent effects of SSB consumption on T2DM and cardiovascular diseases.ResultsThe model results indicated that for all four countries, in 1 year, SSB consumption was associated with 18 000 deaths (3.2% of the total disease-related deaths), seven million disease events (3.3% of the total disease-related events), a half-million DALYs and US$2 billion in direct medical costs. This included 1.5 million cases of overweight and obesity in children/adolescents (12% of the excess weight cases) and 2.8 million cases in adults (2.8%); 2.2 million cases of type 2 diabetes (19%); 200 000 cases of heart disease (3.8%); 124 000 strokes (3.9%); 116 000 cases of musculoskeletal disease (0.2%); 102 000 cases of kidney disease (0.9%); and 45 000 episodes of asthma (0.4%). The Trinidad and Tobago population were the most affected by disease events.ConclusionsThe study results indicate that the consumption of SSBs is associated with a significant burden of disease and death in Latin America and the Caribbean.

Introduction Disease burden due to tobacco smoking in Latin America remains very high. The objective of this study was to evaluate potential impact of implementing smoke-free air interventions on health and cost outcomes in Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru, using a mathematical model. Methods We built a probabilistic Montecarlo microsimulation model, considering natural history, direct health system costs and quality of life impairment associated with main tobacco-related diseases. We followed individuals in hypothetical cohorts and calculated health outcomes on an annual basis to obtain aggregated 10-year population health outcomes (deaths, events) and costs. To populate the model, we completed an overview and systematic review of literature. Also, we calibrated the model comparing the predicted disease-specific mortality rates with those coming from local national statistics. Results With current policies, over 10 years, of 137,121 deaths and 917,210 events could be averted, adding 3.84 million years of healthy life and saving USD 9.2 billion in these seven countries. If countries fully implemented smoke-free air strategies, it would be possible avert nearly 180,000 premature deaths and 1,2 million events, adding 5 million healthy years of life and saving USD 13.1 billion in direct healthcare. Conclusion Implementing the smoke-free air strategy would substantially reduce deaths, diseases, and health care costs attributed to smoking. Latin American countries should not delay the full implementation of this strategy. Implications Tobacco smoking is the single most preventable and premature mortality cause in the world. The Framework Convention on Tobacco Control, supported by the World Health Organization, introduced a package of evidence-based measures for tobacco control. This study adds quality evidence on the potential health effects and savings of implementing smoke-free air policies in countries representing almost 80% of the LAC population.

El objetivo fue describir experiencias, barreras y facilitadores en la implementación de intervenciones de control del Aedes aegypti en América Latina y Caribe. Fue realizado un abordaje cualitativo con entrevistas en profundidad semiestructuradas a expertos en implementación de programas (19 participantes de nueve países). Se utilizó un software para la codificar los datos y se confeccionaron matrices para su comparación. En base a los hallazgos desarrollamos una representación gráfica de dimensiones teóricas que agrupan las barreras y facilitadores para la implementación de intervenciones. A nivel global, el ambiente natural y construido contribuye a la reproducción del mosquito. En el sistema de salud, la falta de priorización del problema y la escasez de recursos materiales y humanos representan los obstáculos más importantes. Se necesita que otros sectores diferentes al de salud se responsabilicen de las acciones para mejorar los determinantes sociales de la salud. Existen barreras transversales relacionadas con la gobernanza, como la descoordinación entre los niveles centrales y locales, falta de continuidad de las intervenciones y de los grupos técnicos. La comunidad enfrenta problemas como la falta de información, pobreza o resistencias a recomendaciones. La opinión pública puede tener un impacto positivo o negativo, influyendo indirectamente en las decisiones políticas. Este estudio propone un marco de dimensiones de análisis construido desde los hallazgos; describe factores influyentes en la implementación de políticas que pueden orientar las acciones futuras desde un enfoque integrado.

This article presents the results of a dialogue between decision-makers and experts in Latin America and the Caribbean on priority-setting for interventions and studies on Aedes aegypti control. The article is part of a project that included a systematic review of mosquito control strategies and a qualitative study with key informants from the region. Using a collective deliberative process assisted by the results of the above-mentioned projects, a list of priorities was developed by consensus for the implementation of vector control strategies and the development of key regional research lines. It was agreed that the best strategy is integrated vector management, divided into: (a) chemical control; (b) biological control; (c) environmental management; (d) community participation; and (e) integrated surveillance. The workshop highlighted the crucial role of government leadership and inter-sector coordination between government agencies and civil society stakeholders. The proposed priorities for research lines were: Ae. aegypti vector competence and associated factors; community components of interventions; incorporation of technology into vector control and monitoring; most efficient modalities of integrated surveillance; entomological indicators with the best predictive capacity; and resistance to insecticides. The policy dialogue methodology allowed validating and enriching the results of other levels of research, besides establishing priorities for regional research and control strategies.

To conduct a cost-utility evaluation of dabigatran etexilate compared with enoxaparin for the prevention of venous thromboembolism (VTE) after total knee replacement (TKR) and total hip replacement (THR) in Colombia. METHODS: An acute phase model, using decision analysis, and a long-term simulation Markov model were developed to compare the clinical outcomes, utilities, and direct medical costs of dabigatran 220 mg once daily and subcutaneous enoxaparin 40 mg once daily for VTE prophylaxis after TKR or THR. Time frame for the acute inpatient-phase was 14 days for TKR and 30 days for THR; adjustments for adverse events and average length of hospital stay were performed. The long-term simulation was performed using 6-months cycle transitions to eight health states for both TKR and THR. Transition probabilities for VTE and bleeding events were derived from Phase III studies comparing the two treatments. The probabilities of long-term events were estimated using data from published longitudinal studies. The payer perspective for a lifetime horizon was used. Sensitivity analyses were performed to assess the model robustness. The annual discount rate was set at 3.
