Bilateral testicular myxosarcoma in a cryptorchid dog.

Myxosarcoma is a rare malignant mesenchymal neoplasm of soft tissues originating from fibroblasts. This report describes a case of bilateral myxosarcoma in a three-year-old cryptorchid dog. The animal was referred to the veterinary clinic because of the absence of testicles in the scrotum. Ultrasonography revealed two masses in the abdominal cavity with testicular echotexture. Exploratory laparotomy revealed the presence of cryptorchid testicles, and orchiectomy was recommended to treat the animal. Testicles were gray and reddish in color and enlarged with firm consistency. For histopathological analysis, testis fragments were fixed in 10% formalin and stained with hematoxylin and eosin and Alcian blue. Immunohistochemistry was performed using the following primary antibodies:1A4, HHF35, desmin, glial fibrillary acidic protein, CD31, S-100, vimentin, and Ki-67. Histopathological evaluation revealed the proliferation of fusiform and round cells associated with extensive areas of myxoid matrix. Neoplasms featured multinucleated giant cells, pleomorphism, karyomegaly, nuclear hyperchromasia, anisokaryosis, mitoses, and necrosis, with coarse chromatin and prominent nucleoli. Immunohistochemical analysis of vimentin- and the Alcian blue-positive cells confirmed the diagnosis of myxosarcoma. A high mitotic count and Ki-67 proliferative index suggests this myxosarcoma had a high degree of malignancy. To the best of our knowledge, this is the first case report of bilateral testicular myxosarcoma in a cryptorchid animal.

Latin America and the Caribbean Code Against Cancer 1st edition: Tobacco and nicotine-related products, secondhand smoke, and alcohol and cancer.

Tobacco, secondhand smoke (SHS), and alcohol, all carcinogens, are leading preventable cancer risk factors in Latin America and the Caribbean (LAC). Since 2000, smoking and SHS exposure have significantly decreased in the region. Yet alcohol consumption remains high. The entry of nicotine-related products such as electronic cigarettes (e-cigs) threatens achievements made in tobacco control and chronic diseases prevention, including cancer. E-cigs use is likely associated with smoking initiation among adolescents who had never smoked and dual use with combustible tobacco products. Therefore, the LAC Code Against Cancer recommends to the public actions they can take to reduce their risk of cancer: 1. Don't smoke or use any type of tobacco. If you do, quitting is possible, with professional help if needed. Don't use e-cigarettes either, as they lead to tobacco use. 2. Make your home a smoke-free place. Respect and promote laws that ensure smoke-free spaces to protect our health. and 3. Avoid drinking alcoholic beverages. This helps prevent several types of cancer. The Code recommends to policymakers a package of cost-effective policies based on the MPOWER and SAFER to prevent cancer at the population level. It also recommends that primary care health professionals: 1. Ask all their patients and their families whether they smoke or vape, inform them about the harms of smoking and vaping, and promote tobacco and nicotine related products cessation strategies among users. 2. Inform about the harms of exposure to SHS, especially among children, and promote smoke-free environments, and 3. Prevent alcohol use by their patients and their families, use tools to assess use, intensity, and frequency, and apply brief counseling intervention to support alcohol abstinence in primary care.

Latin American and the Caribbean Code Against Cancer 1st edition: Weight, physical activity, diet, breastfeeding, and cancer.

In Latin America and the Caribbean a considerable proportion of the population have excess body weight, do not meet the recommendations of physical activity and healthy diet, and have suboptimal rates of breastfeeding. Excess body weight is associated with at least 15 cancer sites, physical activity protects against three cancers, with some evidence suggesting a protective effect for eight more cancer sites, and sedentary behavior probably increases the risk of five cancer sites. Fiber and wholegrains protect against colorectal cancer, high intake of fruits and vegetables could reduce the risk of aerodigestive cancers; processed and red meat increase the risk of colorectal cancer; and very hot beverages are associated with esophageal cancer. Moreover, sugar-sweetened beverages and ultra-processed foods are a convincing cause for excess body weight, increasing cancer risk through this pathway, with some emerging evidence suggesting also direct pathways. Breastfeeding protects against breast cancer, and could protect against ovarian cancer. Taking this evidence into account, the Latin America and the Caribbean Code Against Cancer recommends the general public to maintain a healthy body weight, be physically active and limit sedentary behavior, eat a healthy diet (eat plenty of vegetables, fruits, wholegrains and legumes; avoid sugar-sweetened beverages and processed meat; and limit ultra-processed foods, red meat and very hot beverages), and breastfeed. Moreover, the Latin America and the Caribbean Code Against Cancer also includes a set of public policy recommendations for cancer prevention to inform policy makers and civil society about the need of policies to shape healthy environments and create opportunities to facilitate the adoption of the recommendations directed to the public.

Abortion and congenital transmission of Trypanosoma vivax in goats and ewes in semiarid northeastern Brazil.

The main effects of trypanosomosis in Brazil are related to reproductive alterations. In this context, the present study aimed to report the occurrence of abortions in goats and sheeps in the semiarid region of Northeastern Brazil, associated with Trypanosoma vivax. Trypomastigotes forms visualized by Buffy coat technique (BCT) method in 68.7% of the goats and 50.0% of the ewes that aborted. PCR identified that 100% of the goats and ewes that aborted were infected with T. vivax. The goats and ewes that aborted showed high parasitemia and developed clinical signs of trypanosomosis. The presence of T. vivax DNA was identified in the blood of fetuses by the PCR technique, proving infection by T. vivax in aborted fetuses, as well as confirming the congenital transmission of the parasite.

Indicators related to smoking cessation in Brazil, National Health Survey, 2013 and 2019 editions. / Indicadores referentes à cessação do comportamento de fumar no Brasil, Pesquisa Nacional de Saúde, edições 2013 e 2019.

OBJECTIVE: To describe the indicators of smoking cessation in 2013 and 2019 for Brazil and federative units, according to sociodemographic variables, collected in the National Health Survey (PNS). METHODS: Cross-sectional, population-based and descriptive study with data from the 2013 and 2019 PNS, a household survey collected by trained interviewers. The prevalence of ex-smokers and the proportion of smokers who tried to quit smoking in the 12 months prior to the interview, and respective confidence intervals (95%CI) were calculated, according to sociodemographic variables. Additionally, the percentage variation between the years was calculated. RESULTS: In 2013, the prevalence of ex-smokers was 17.5% (95%CI 16.9;18.0) and, in 2019, 26.6% (95%CI 26.1;27.2). In 2013, 51.1% tried to quit smoking (95%CI 49.3;52.9) and, in 2019, 46.6% (95%CI 45.0;48.3). CONCLUSION: It is important to strengthen and maintain strategies for coping with tobacco use in Brazil, to increase the current smoker's willingness and ability to quit smoking.

"Tobacco denormalization at home": the contribution of the smoking ban in enclosed workplaces in Brazil.

Estimates suggest that exposure to environmental tobacco smoke is related to 1.2 million deaths per year worldwide. Synergy between various anti-smoking legislative and educational measures is essential to stimulate cessation and prevent initiation. This article aimed to explore how legislative protection from exposure to environmental tobacco smoke in enclosed workplaces in Brazil, whose strengthening occurred in a phased manner between 1996 and 2014, possibly contributed to the protection from passive smoking at home. We evaluated, via generalized linear models, the absolute and relative differences in the proportion of individuals living in smoke-free homes between those exposed and not exposed to passive smoking in enclosed workplaces, both crude and adjusted by sociodemographic and smoking behavior variables, and stratified by non-smokers and smokers. Data from three national surveys conducted in 2008, 2013, and 2019 were used. Regardless of smoking status and year when the data were analyzed, individuals who were employed in smoke-free workplaces were more likely to live in smoke-free homes than smokers who were employed in workplaces that allowed smoking. Adjusted absolute difference increased from +5.5% in 2008 to +10.5% in 2013 among non-smokers, and from +7.1% in 2013 to 15.6% in 2019 among smokers (p-values for additive interaction ≤ 0.05). Strengthening the Brazilian smoke-free legislation was likely associated with a reduction in passive smoking at home, which, therefore, may also reduce the burden of mortality, morbidity, and costs for society related to smoking.

Estima-se que a exposição à fumaça ambiental de tabaco esteja relacionada a 1,2 milhão de mortes por ano no mundo. A sinergia das diversas medidas antitabaco, tanto legislativas quanto educativas, é essencial para estimular a cessação e prevenir a iniciação do tabagismo. O artigo tem como objetivo explorar a possível contribuição da proteção legislativa contra a exposição à fumaça ambiental de tabaco nos locais fechados de trabalho no Brasil, cujo fortalecimento ocorreu por fases entre 1996 e 2014, para a proteção contra o tabagismo passivo em casa. Foram utilizados modelos lineares generalizados para avaliar as diferenças absolutas e relativas na proporção de brasileiros que vivem em domicílios sem fumaça ambiental de tabaco, entre aqueles expostos e não expostos ao tabagismo passivo em locais de trabalho fechados, brutas e ajustadas por variáveis sociodemográficas e de comportamento de tabagismo, estratificadas entre fumantes e não fumantes. Foram usados os dados de três inquéritos nacionais, realizados em 2008, 2013 e 2019. Independentemente de condição de tabagista e do ano de análise, os indivíduos empregados em locais de trabalho livres de tabaco apresentaram maior probabilidade de residir em domicílios livres de tabaco, comparado com aqueles que trabalhavam em locais onde fumar era permitido. A diferença absoluta ajustada aumentou de +5,5% em 2008 para +10,5% em 2013 entre não fumantes, e de +7,1% em 2013 para +15,6% em 2019 entre fumantes (valores de p de interação aditiva ≤ 0,05). É provável que o fortalecimento da legislação antitabaco no Brasil esteve associado a uma redução no tabagismo passivo em casa, o que, portanto, pode reduzir a carga de morbimortalidade e de custos para a sociedade, relacionados ao tabagismo.

Se estimó que la exposición al humo del tabaco ambiental está relacionada con 1,2 millones de muertes por año en todo el mundo. La sinergia de varias medidas antitabaco legislativas y educacionales es esencial para estimular dejar de fumar y prevenir comenzar a fumar. La propuesta de este artículo fue explorar la posible contribución de la protección legislativa ante la exposición al humo del tabaco ambiental en lugares de trabajo cerrados en Brasil, cuyo afianzamiento se produjo de manera gradual entre 1996 y 2014, para la protección de los fumadores pasivos en casa. Se utilizaran modelos lineales generalizados para evaluar las diferencias absolutas y relativas en la proporción de individuos que viven en hogares libres de humos, entre quienes estaban expuestos y no expuestos como fumadores pasivos en lugares de trabajo cerrados, crudas y ajustadas por variables sociodemográficas y comportamiento de fumador, y estratificadas por no fumadores y fumadores. Se usaron los datos de las tres encuestas nacionales llevadas a cabo en 2008, 2013 y 2019. Independientemente del estatus del consumo de tabaco y el año de análisis, los individuos que fueron empleados en un lugar de trabajo libre de humos tenían más probabilidades de vivir en un hogar libre de humos en comparación con los fumadores que trabajaban en donde se fumaba. La diferencia ajustada absoluta aumentó del +5,5% en 2008 al +10,5% en 2013 entre no fumadores, y del +7,1% en 2013 al +15,6% en 2019 entre fumadores (valores de p de interacción aditiva ≤ 0,05). El fortalecimiento de la legislación antitabaco en Brasil estuvo presumiblemente asociado con una reducción con los fumadores pasivos en el hogar, y, por consiguiente, podría también reducir la carga de mortalidad, morbilidad y costes para la sociedad en relación con el tabaquismo.

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: where are we going?

OBJECTIVE: To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. METHODS: We used data from the 2019 National Health Survey to estimate the prevalence of lifetime and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the III Brazilian Household Survey on Substance Use-2015 and the National Health Survey-2013. RESULTS: For 2019, the prevalence of current use of ENDS was estimated at 0.64% (∼1 million people), of which ∼70% were in the age group of 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast region concentrates half of these users. Almost 90% are non-smokers, with high prevalence among those who also use waterpipe and abuse alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (∼800,000 individuals), of which ∼80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ∼300%. CONCLUSIONS: In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of ENDS and waterpipe has been increasing even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

Contributions of the analysis of discarded cigarette packages in household waste in the Brazilian city of Rio de Janeiro, Brazil, to estimate the illegal market. / Contribuições da análise de embalagens de cigarros descartadas nos resíduos domiciliares do Município do Rio de Janeiro, Brasil, para estimativa de mercado ilegal.

The illicit trade of tobacco products, by enabling access to cheaper cigarettes, favors smoking initiation and hinders its cessation, minimizing the effects of price policy and taxes on reducing the demand for tobacco. This is especially the case among populations with lower income and schooling, where smoking is concentrated. Its confrontation requires multisectoral actions, aligned with the World Health Organization Framework Convention on Tobacco Control, supported by estimates of the illicit trade magnitude and the analysis of its characteristics. This study analyzes, based on samples of household solid waste collected in 2018 in the city of Rio de Janeiro, Brazil, the conformity of discarded cigarette packages with criteria for their regular commercialization in Brazil, classifying them as legal or illegal. The evaluation was also carried out for the 15 Planning Areas (PA) of the municipality. The Social Progress Index (SPI) was chosen to represent heterogeneities among PA. The average percentage of illegal cigarette packs found was 26.79%, ranging from 3.36% to 46.29% among PA. The PAs with high illegality presented lower Social Progress Index and lower percentages of legal cigarette packages with a price equal to or greater than BRL 7.25. Among the illegal packages, 98.07% were manufactured in Paraguay. The study contributes methodologically to measure the consumption of illegal cigarettes in the second economic capital of Brazil, supporting the National Tobacco Control Policy in the struggle against illicit trade of tobacco products and in the effective implementation of the pricing and tax policy on these products.

O comércio ilícito de produtos de tabaco, ao possibilitar acesso a cigarros mais baratos, favorece a iniciação do tabagismo e dificulta sua cessação, minimizando os efeitos da política de preços e impostos sobre a redução da demanda por tabaco, sobretudo entre populações de menor renda e escolaridade, onde se concentra o tabagismo. Seu enfrentamento requer ações multissetoriais, alinhadas à Convenção-Quadro para o Controle do Tabaco da Organização Mundial da Saúde e seus protocolos, e respaldadas em estimativas de sua magnitude e na análise de suas características. O estudo pretende analisar, por meio de amostras de resíduos sólidos domiciliares coletados em 2018 no Município do Rio de Janeiro, Brasil, a conformidade das embalagens de cigarros descartadas com critérios para a sua comercialização regular no país, classificando-as como legais ou ilegais. A avaliação foi feita também para as 15 Áreas de Planejamento (AP) do município. Escolheu-se o Índice de Desenvolvimento Social (IDS) para representar as heterogeneidades entre as AP. O percentual médio de embalagens de cigarros ilegais encontrado foi de 26,79%, variando de 3,36% a 46,29% entre as AP. As AP com alta ilegalidade apresentavam menores IDS e menores percentuais de embalagens de cigarros legais com preço igual ou superior a R$ 7,25. Dentre as embalagens ilegais, 98,07% apresentavam o Paraguai como país fabricante. O estudo contribui metodologicamente para dimensionar o consumo de cigarros ilegais na segunda capital econômica do Brasil, subsidiando a Política Nacional de Controle do Tabaco no combate ao comércio ilícito de produtos de tabaco e na efetiva implementação da política de preços e impostos sobre estes produtos.

Su combate requiere acciones multisectoriales, alineadas con la Convención-Marco para el Control del Tabaco de la Organización Mundia de la Salud, y sus protocolos, y respaldadas en estimaciones de su magnitud y en el análisis de sus características. El estudio pretende analizar, mediante muestras de residuos sólidos domiciliarios, recogidos en 2018 en el Municipio de Rio de Janeiro, Brasil, la conformidad de los paquetes de cigarrillos tirados a la basura con criterios para su comercialización regular en el país, clasificándolos como legales o ilegales. La evaluación se realizó también para las 15 Áreas de Planificación (AP) del municipio. Se escogió el Índice de Desarrollo Social (IDS) para representar heterogeneidades entre las AP. El porcentaje medio de paquetes de cigarrillos ilegales encontrado fue de un 26,79%, variando de 3,36% a 46,29% entre las AP. Las AP con alta ilegalidad presentaban menores IDS y menores porcentajes de paquetes de cigarrillos legales con un precio igual o superior a BRL 7,25. Entre los embalajes ilegales, un 98,07% presentaban Paraguay como el país fabricante. El estudio contribuye metodológicamente para dimensionar el consumo de cigarrillos ilegales en la segunda capital económica de Brasil, apoyando la Política Nacional de Control del Tabaco en el combate al comercio ilícito de productos del tabaco y en la efectiva implementación de la política de precios e impuestos sobre estos productos.

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: Where are we going? / Prevalência de uso de dispositivos eletrônicos para fumar e de uso de narguilé no Brasil: Para onde estamos caminhando?

Objective: To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. Methods: We used data from the 2019 National Health Survey (PNS) to estimate the prevalence of ever and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the BHSU-III-2015 (III Brazilian Household Survey on Substance Use) and the PNS-2013. Results: For 2019, the prevalence of current use of ENDS was estimated at 0.64% (~ 1 million people), of which ~70% were 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast concentrates half of these users. Almost 90% are non-smokers, and higher prevalence were found among those who also use waterpipe and abusive alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (~ 800,000 individuals), of which ~80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ~300%. Conclusions: In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of DEF and waterpipe has been increasing, even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

Objetivo: Descrever as prevalências de uso de dispositivos eletrônicos para fumar (DEF) e de narguilé no Brasil, por subgrupos populacionais, e avaliar tendência entre 2013 e 2019. Métodos: Os dados principais analisados são da Pesquisa Nacional de Saúde (PNS) de 2019. Estimou-se prevalências de uso na vida e atual de DEF e de uso atual de narguilé segundo características sócio-comportamentais. Os dados da PNS-2019 sobre DEF foram comparados aos do III-LNUD-2015 (III Levantamento Nacional sobre Uso de Drogas pela População Brasileira) e os dados sobre narguilé comparados à PNS-2013. Resultados: Para 2019, estimou-se a prevalência de uso atual de DEF em 0,64% (~1 milhão de pessoas), dos quais ~70% tinham 15-24 anos. Maior prevalência está na região Centro-Oeste, mas o Sudeste concentra metade absoluta desses usuários. Quase 90% são não fumantes, e maiores prevalências foram encontradas entre quem usa também narguilé e álcool abusivo. Observou-se aumento nas estimativas de uso de DEF entre 2015 e 2019, especialmente entre os mais jovens. A prevalência de uso atual de narguilé em 2019 foi estimada em 0,47% (~800 mil indivíduos), dos quais ~80% tinham 15-24 anos. Houve aumento na prevalência de uso atual de narguilé entre 2013 e 2019, e entre jovens o aumento foi de ~300%. Conclusões: No Brasil os DEF têm sido utilizados majoritariamente por jovens, e por nunca fumantes de cigarros industrializados. O uso de DEF e de narguilé vêm aumentando, mesmo com as restrições regulatórias do país, podendo comprometer o exitoso histórico da política de controle do tabagismo.

Resumo: O comércio ilícito de produtos de tabaco, ao possibilitar acesso a cigarros mais baratos, favorece a iniciação do tabagismo e dificulta sua cessação, minimizando os efeitos da política de preços e impostos sobre a redução da demanda por tabaco, sobretudo entre populações de menor renda e escolaridade, onde se concentra o tabagismo. Seu enfrentamento requer ações multissetoriais, alinhadas à Convenção-Quadro para o Controle do Tabaco da Organização Mundial da Saúde e seus protocolos, e respaldadas em estimativas de sua magnitude e na análise de suas características. O estudo pretende analisar, por meio de amostras de resíduos sólidos domiciliares coletados em 2018 no Município do Rio de Janeiro, Brasil, a conformidade das embalagens de cigarros descartadas com critérios para a sua comercialização regular no país, classificando-as como legais ou ilegais. A avaliação foi feita também para as 15 Áreas de Planejamento (AP) do município. Escolheu-se o Índice de Desenvolvimento Social (IDS) para representar as heterogeneidades entre as AP. O percentual médio de embalagens de cigarros ilegais encontrado foi de 26,79%, variando de 3,36% a 46,29% entre as AP. As AP com alta ilegalidade apresentavam menores IDS e menores percentuais de embalagens de cigarros legais com preço igual ou superior a R$ 7,25. Dentre as embalagens ilegais, 98,07% apresentavam o Paraguai como país fabricante. O estudo contribui metodologicamente para dimensionar o consumo de cigarros ilegais na segunda capital econômica do Brasil, subsidiando a Política Nacional de Controle do Tabaco no combate ao comércio ilícito de produtos de tabaco e na efetiva implementação da política de preços e impostos sobre estes produtos.

Resumen: El comercio ilícito de productos del tabaco, al posibilitar el acceso a cigarrillos más baratos, favorece la iniciación del tabaquismo y dificulta la interrupción de su consumo, minimizando los efectos de la política de precios e impuestos sobre la reducción de la demanda de tabaco, sobre todo entre poblaciones de menor renta y escolaridad, donde se concentra el tabaquismo. Su combate requiere acciones multisectoriales, alineadas con la Convención-Marco para el Control del Tabaco de la Organización Mundia de la Salud, y sus protocolos, y respaldadas en estimaciones de su magnitud y en el análisis de sus características. El estudio pretende analizar, mediante muestras de residuos sólidos domiciliarios, recogidos en 2018 en el Municipio de Rio de Janeiro, Brasil, la conformidad de los paquetes de cigarrillos tirados a la basura con criterios para su comercialización regular en el país, clasificándolos como legales o ilegales. La evaluación se realizó también para las 15 Áreas de Planificación (AP) del municipio. Se escogió el Índice de Desarrollo Social (IDS) para representar heterogeneidades entre las AP. El porcentaje medio de paquetes de cigarrillos ilegales encontrado fue de un 26,79%, variando de 3,36% a 46,29% entre las AP. Las AP con alta ilegalidad presentaban menores IDS y menores porcentajes de paquetes de cigarrillos legales con un precio igual o superior a BRL 7,25. Entre los embalajes ilegales, un 98,07% presentaban Paraguay como el país fabricante. El estudio contribuye metodológicamente para dimensionar el consumo de cigarrillos ilegales en la segunda capital económica de Brasil, apoyando la Política Nacional de Control del Tabaco en el combate al comercio ilícito de productos del tabaco y en la efectiva implementación de la política de precios e impuestos sobre estos productos.

Abstract: The illicit trade of tobacco products, by enabling access to cheaper cigarettes, favors smoking initiation and hinders its cessation, minimizing the effects of price policy and taxes on reducing the demand for tobacco. This is especially the case among populations with lower income and schooling, where smoking is concentrated. Its confrontation requires multisectoral actions, aligned with the World Health Organization Framework Convention on Tobacco Control, supported by estimates of the illicit trade magnitude and the analysis of its characteristics. This study analyzes, based on samples of household solid waste collected in 2018 in the city of Rio de Janeiro, Brazil, the conformity of discarded cigarette packages with criteria for their regular commercialization in Brazil, classifying them as legal or illegal. The evaluation was also carried out for the 15 Planning Areas (PA) of the municipality. The Social Progress Index (SPI) was chosen to represent heterogeneities among PA. The average percentage of illegal cigarette packs found was 26.79%, ranging from 3.36% to 46.29% among PA. The PAs with high illegality presented lower Social Progress Index and lower percentages of legal cigarette packages with a price equal to or greater than BRL 7.25. Among the illegal packages, 98.07% were manufactured in Paraguay. The study contributes methodologically to measure the consumption of illegal cigarettes in the second economic capital of Brazil, supporting the National Tobacco Control Policy in the struggle against illicit trade of tobacco products and in the effective implementation of the pricing and tax policy on these products.

Occurrence of green tobacco sickness and associated factors in farmers residing in Dom Feliciano Municipality, Rio Grande do Sul State, Southern Region of Brazil.

This study aimed to evaluate the occurrence of the green tobacco sickness (GTS) and its associated factors in tobacco familiar farmers residing in Dom Feliciano, Rio Grande do Sul State, Brazil. A cross-sectional study was conducted evaluating the sickness in 354 small tobacco farmers, between October 2011 and March 2012. The urinary concentration of cotinine, a biomarker of exposure to nicotine, was determined during the tobacco harvest period. Subjects presenting cotinine urinary levels ≥ 50ng/mL, that had contact with tobacco leaves up to 48 hours before the sample collection and reported at least one disease symptom were deemed as cases. A non-conditional logistic analysis was performed to evaluate the association between GTS and the population characteristics. A total of 122 (34.5%) cases were identified, with 39% of them being smokers and 61% being males. The median cotinine urinary concentrations were 75.6ng/mL (74.1ng/mg of creatinine) for non-cases and 755.8ng/mL (632.1ng/mg of creatinine) for the cases (p-value ≤ 0.01). The multivariate analysis showed a positive association between GTS and sunlight exposure time, exposure to pesticides, worse health status, and inverse association with wood cultivation. This study presented a high GTS prevalence and suggest that the use of urinary cotinine is a significant biomarker to determine GTS cases, influencing in the distribution by sex. Once the tobacco production involves health hazards, is important to implement measures to prevent the harm caused to tobacco farmers, as set in articles 17 and 18 of the World Health Organization Framework Convention on Tobacco Control.

Culture of goat preantral follicles in situ associated with mesenchymal stem cell from bone marrow.

This study aims to develop an in vitro co-culture system of in situ goat preantral follicles with bone marrow-derived mesenchymal stem cells (BM-MSC), evaluating the influence of these cells on follicular growth, rate of activation and morphologically normal follicles. Fragments of ovarian cortex were cultured for 1 or 7 days in the presence of BM-MSC (BM-MSC+) and absence of BM-MSC (BM-MSC-). Histological sections of the fragments were analysed and data were obtained regarding morphological classification, survival rate of morphologically normal follicles and rate of follicular activation. Culture medium on days 1 and 7 was also sampled for nitrite concentration and reduced glutathione activity. There was a reduction (P < 0.05) in the percentage of morphologically normal follicles in the BM-MSC+ compared with the fresh control only on the seventh day of culture. When comparing treatments, on the seventh day of culture, a higher rate of morphologically normal preantral follicles was observed in BM-MSC+ (P < 0.05). In both treatments, primordial and developing follicle rates were similar to the fresh control (P > 0.05). When comparing treatments with each other, as well as with the fresh control, no differences were observed in follicular diameter (P > 0.05) or nitrite concentration (P > 0.05). The concentration of reduced glutathione was lower on the seventh day of co-culture in both treatments (P < 0.05). In conclusion, co-culture had no influence on follicular or oocyte development. However, it was critical to maintain the survival of preantral follicles during 7 days of culture.

Interferência da Indústria do Tabaco no Brasil: a Necessidade do Ajuste de Contas / Tobacco Industry Interference in Brazil: the Necessity of Settling Accounts / Interferencia de la Industria Tabacalera en Brasil: la Necesidad del Ajuste de Cuentas

Introdução: No Brasil, cada vez mais são identificadas ações ilegais de publicidade, propaganda e patrocínio por parte da indústria do tabaco em eventos musicais e por meio das redes sociais, voltadas a atrair principalmente o público jovem para o uso do cigarro. Objetivo: Desenvolver uma metodologia que permita estabelecer um parâmetro de quantificação dos impactos negativos para o setor saúde desse descumprimento da lei. Método: Combinaram-se as informações nacionais existentes sobre i) a equivalência entre "custo direto médio da assistência médica" e "mortes por doenças atribuíveis ao tabagismo" e ii) a equivalência entre "a parcela do lucro revertido em ações de marketing" e "mortes de fumantes que contribuíram para a geração desse lucro por meio da compra de cigarros", de forma a se obter a relação "custo direto do tratamento" vs "parcela do lucro revertido em ações de marketing". As doenças selecionadas foram aquelas que apresentam os maiores custos diretos de tratamento atribuíveis ao fumo. Resultados: Para cada centavo investido em marketing pela indústria do tabaco, o Brasil tem um gasto com tratamento de doenças relacionadas ao tabaco 1,93 vezes superior ao dinheiro investido pela indústria. Conclusão: A mensuração da responsabilização dos violadores da legislação nacional para o controle do tabaco é fundamental para compensar parte dos custos associados ao tratamento de pacientes e aos programas de cessação ao fumo, favorecendo assim a redução do tabagismo no país.

Introduction: In Brazil, illegal actions of advertising, promotion, and sponsorship by part of the tobacco industry are increasingly identified in music events, and through social media, aimed mainly to attract young people to use cigarettes. Objective: To develop a methodology that allows the creation of a parameter of quantification of the negative impacts to the health sector of non-compliance with the law. Method: Combination of the current national information about i) the equivalence between "mean direct cost of medical care" and "deaths by diseases attributable to tobacco addiction" and ii) the equivalence between "the portion of the profit translated into marketing actions" and "deaths of smokers who contributed for the generation of this profit through purchase of cigarettes" in order to obtain the relation between "direct cost of the treatment" vs "portion of the profit translated into market actions". The diseases selected were those that presented the biggest direct cost of treatment attributable to tobacco. Results: For every cent invested in marketing strategies by the tobacco industry, Brazil spends 1.93 times more financial resources to treat tobacco-related diseases. Conclusion: The measurement of the liability for non-compliance of the tobacco national legislation is essential to offset part of the associated costs of the treatment of patients and programs of tobacco cessation to favor the reduction of smoking prevalence in Brazil.

Introducción: En Brasil, es cada vez más común identificar acciones ilegales de publicidad, promoción y patrocinio del tabaco por parte de la industria tabacalera en eventos musicales y a través de redes sociales, destinadas principalmente a atraer al público joven al consumo de cigarrillos. Objetivo: Desarrollar una metodología que permita establecer un parámetro para cuantificar los impactos negativos al setor de la salud de esa acción ilegal de la ley. Método: El artículo integra la información nacional existente sobre i) la equivalencia entre el "costo directo promedio de asistencia médica" y "muertes por enfermedades atribuibles al tabaquismo" y ii) la equivalencia entre "la parte del ingreso usado en acciones de marketing" y "las muertes de fumadores que han contribuido a la generación de estos ingresos a través de la compra de cigarrillos", para obtener la relación "costo directo del tratamiento" vs "parte de los ingresos usados en acciones de marketing". Las enfermedades seleccionadas fueron las que presentaron los costos más altos de tratamiento directo atribuibles al uso del tabaco. Resultados: Por cada centavo invertido en marketing por la industria tabacalera, Brasil tiene un gasto en tratamiento de enfermedades relacionadas con el tabaco 1,93 veces mayor que el monto invertido por la industria. Conclusión: Medir la responsabilidad de los infractores de la legislación nacional de control del tabaco es esencial para compensar parte de los costos asociados con el tratamiento de los pacientes y com los programas para dejar de fumar, favoreciendo así la reducción del consumo de tabaco en el país.

Resumo: O estudo teve como objetivo avaliar a ocorrência de doença da folha verde (DFV) e fatores associados entre fumicultores familiares no Município de Dom Feliciano, Estado do Rio Grande do Sul, Brasil. Foi realizado um estudo transversal sobre DFV em 354 pequenos produtores de tabaco, entre outubro de 2011 e março de 2012. Foi medida a concentração urinária da cotinina, um biomarcador da exposição à nicotina, durante a temporada de colheita do tabaco. Os casos de DFV foram definidos como indivíduos com níveis urinários de cotinina ≥ 50ng/mL, que tiveram contato com folhas de tabaco em até 48 horas antes da coleta da amostra sanguínea e que relatavam pelo menos um sintoma da doença. Foi realizada uma análise logística não condicional para avaliar a associação entre DFV e as características da população. Foram identificados um total de 122 (34,5%) casos da doença, entre os quais 39% eram fumantes e 61% eram do sexo masculino. As concentrações urinárias medianas de cotinina foram 75,6ng/mL (74,1ng/mg de creatinina) para não-casos e 755,8ng/mL (632,1ng/mg de creatinina) para os casos (valor de p ≤ 0,01). A análise multivariada mostrou uma associação positiva entre DFV e tempo de exposição à luz solar, exposição a pesticidas e pior estado de saúde geral, e uma associação inversa com cultivo de lenha. O estudo identificou alta prevalência de DFV e sugere o uso da cotinina como biomarcador significativo para identificar os casos de DFV, influenciando a distribuição por sexo. Uma vez que a fumicultura envolve danos à saúde, é importante implementar medidas para prevenir os impactos para os fumicultores, de acordo com os artigos 17 e 18 da Convenção-Quadro para o Controle do Tabaco da Organização Mundial da Saúde.

Resumen: Este estudio visó evaluar la ocurrencia de la enfermedad del tabaco verde (GTS por sus siglas en inglés) y sus factores asociados en pequeños agricultores de tabaco, que residen en Dom Feliciano, Rio Grande do Sul, Brasil. Se realizó un estudio transversal, evaluando la enfermedad del tabaco verde, en 354 pequeños agricultores de tabaco, entre octubre de 2011 y marzo 2012. La concentración urinaria de cotinina, un biomarcador de la exposición a la nicotina, se determinó durante el periodo de cosecha del tabaco. Los individuos que presentan niveles de cotinina urinarios ≥ 50ng/mL, que tuvieron contacto con hojas de tabaco hasta 48 horas antes de la recogida de la muestra, e informaron de al menos un síntoma de la enfermedad, fueron considerados casos. Se realizó un análisis logístico no condicional para evaluar la asociación entre GTS y las características de la población. Se identificaron un total de 122 (34,5%) casos, siendo un 39% de ellos fumadores y un 61% hombres. Las concentraciones medias de cotinina urinaria fueron 75,6ng/mL (74,1ng/mg de creatinina) para los no casos y 755,8ng/mL (632,1ng/mg de creatinina) para los casos (valor de p ≤ 0,01). El análisis multivariado mostró una asociación positiva entre el GTS y las horas de exposición a la luz solar, exposición a los pesticidas, un estatus peor de salud, y la asociación inversa con la cultura maderera. Este estudio presentó una alta prevalencia de GTS y sugiere que el uso de la cotinina urinaria es un biomarcador significativo para identificar casos de GTS, influenciando en la distribución por sexo. Debido a que la producción de tabaco implica perjuicios para la salud, es importante implementar medidas para prevenirlos en los agricultores del tabaco, como está estipulado en los artículos 17 y 18 del Convenio Marco para el Control del Tabaco de la Organización Mundial de la Salud.

EAT-Brazil Award for Tobacco Control: a brief description of its first edition.

Smoking is a major global risk factor for preventable death and disability. EAT is an acronym for Education Against Tobacco, a multinational network of physicians and medical students that aims to improve tobacco control by means of school-based prevention targeted at adolescents through counseling, use of software and support materials. The first EAT-Brazil Award, launched in March 2018, was a competition designed to encourage the proposal of objective solutions for tobacco control in Brasil, and identify new talents in the area. Brazilian undergraduate students from any field of study could submit a one-page essay on the subject, competing for the amount of R$ 1000.00 (one thousand reais). There were a total of 39 applicants (20 women and 19 men) from 9 Brazilian states and 18 undergraduate programs, with a mean age of 22.5 years (SD = 3.7). Data from an online anonymous questionnaire answered after the submission of their essays revealed that most applicants were students of institutions from in the state of Minas Gerais (n = 26/39; 66.6%), studied medicine (n = 20/39, 51.3%), and had no prior knowledge of the EAT-Brazil Network (n = 27/39, 69.2%). The winner of the award was Lucas Guimarães de Azevedo, a fourth-year medical student at Federal University of Western Bahia. The next editions of the award should focus on increasing the number of applicants and diversifying their geographical distribution.
