Introdução: O tabagismo pode ser tratado com eficácia por terapias com enfoque na abordagem cognitivo-comportamental, sendo imprescindível a descrição minuciosa desta. Objetivo: Descrever um programa de cessação tabagística com novos procedimentos e avaliar seu índice de sucesso. Métodos: Participantes de um programa de cessação tabagística, baseado em terapias cognitivas comportamentais e farmacológicas, foram acompanhados por um ano, e a taxa de cessação avaliada foi, no mínimo, de seis meses, após pararem de fumar. Foram implementados os seguintes procedimentos: intensificação na frequência dos encontros (duas vezes semanais); data de cessação pré-estabelecida pelos terapeutas do programa, primeiro encontro com apresentação do tratamento, esclarecimento de dúvidas e motivação dos pacientes e participação de ex-tabagistas para incentivar os iniciantes. Resultados: Dos 145 indivíduos que participaram do estudo, observou-se um índice de sucesso de 64,42% durante o acompanhamento. Conclusão: Os novos procedimentos realizados neste programa de cessação tabagística proporcionaram alto índice de sucesso de abstinência, quando comparados a outros da literatura.

OBJECTIVETo evaluate the effects of acute exposure to air pollutants (NO2 and PM10) on hospitalization of adults and older people with cardiovascular diseases in Western São Paulo.METHODSDaily cardiovascular-related hospitalization data (CID10 – I00 to I99) were acquired by the Department of Informatics of the Brazilian Unified Health System (DATASUS) from January 2009 to December 2012. Daily levels of NO2 and PM10 and weather data were obtained from Companhia Ambiental do Estado de São Paulo (CETESB – São Paulo State Environmental Agency). To estimate the effects of air pollutants exposure on hospital admissions, generalized linear Poisson regression models were used.RESULTSDuring the study period, 6,363 hospitalizations were analysed. On the day of NO2 exposure, an increase of 1.12% (95%CI 0.05–2.20) was observed in the interquartile range along with an increase in hospital admissions. For PM10, a pattern of similar effect was observed; however, results were not statistically significant.CONCLUSIONSEven though with values within established limits, NO2 is an important short-term risk factor for cardiovascular morbidity.

IntroductionSarcopenia is characterized by a progressive and generalized decrease of strength and muscle mass. Muscle mass loss is prevalent in patients with chronic obstructive pulmonary disease (COPD) as a result of both the disease and aging. Some methods have been proposed to assess body composition (and therefore identify muscle mass loss) in this population. Despite the high accuracy of some methods, they require sophisticated and costly equipment.AimThe purpose of this study was to infer the occurrence of muscle mass loss measured by a sophisticated method (dual energy X-ray absorptiometry [DEXA]) using a more simple and affordable equipment (dynamometer).MethodsFifty-seven stable subjects with COPD were evaluated for anthropometric characteristics, lung function, functional exercise capacity, body composition, and peripheral muscle strength. A binary logistic regression model verified whether knee-extension strength (measured by dynamometry) could infer muscle mass loss (from DEXA).ResultsPatients with decreased knee-extension strength were 5.93 times more likely to have muscle mass loss, regardless of sex, disease stage, and functional exercise capacity (P=0.045).ConclusionKnee-extension dynamometry was able to infer muscle mass loss in patients with COPD.
