RESUMO
RESUMO: Objetivo: Descrever os principais resultados dos fatores de risco e proteção de doenças crônicas não transmissíveis (DCNT), nas capitais brasileiras e no Distrito Federal, coletados pela Pesquisa Nacional de Saúde (PNS) e pelo Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas Não Transmissíveis por Inquérito Telefônico (Vigitel) no ano de 2013. Métodos Análise de dados advindos da PNS e do Vigitel, pesquisas realizadas no ano de 2013. Foram analisados indicadores sobre tabagismo, consumo de álcool, alimentação e atividade física, segundo sexo, com intervalo de confiança de 95% (IC95%). Resultados: As prevalências encontradas foram: fumantes atuais de cigarro - PNS 12,5% e Vigitel 11,3%; consumo abusivo de bebida alcoólica - PNS 14,9% e Vigitel 16,4%; consumo recomendado de frutas e hortaliças - PNS 41,8% e Vigitel 23,6%; prática de atividade física no tempo livre - PNS 26,6% e Vigitel 33,8%. Conclusão: Os resultados dos indicadores foram semelhantes, em especial quando as perguntas e opções de resposta também eram. As pesquisas são úteis para o monitoramento dos fatores de risco e proteção das DCNT, podendo apoiar programas de promoção da saúde.
ABSTRACT: Objective: To describe risk and protective factors for chronic diseases, in Brazilian capitals and the Federal District, collected by the National Health Survey (PNS) and by the Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey (Vigitel) in 2013. Methods: Data analysis of the studies conducted by the PNS and Vigitel in 2013 was performed. Indicators analyzed were: smoking, alcohol consumption, diet, and physical activity, according to sex, with a 95% confidence interval. Results: The prevalences found were: current cigarette smokers: PNS, 12.5% and Vigitel, 11.3%; abuse of alcoholic beverages: PNS, 14.9% and Vigitel, 16.4%; recommended intake of fruits and vegetables: PNS, 41.8% and Vigitel, 23.6%; and physical activity in leisure time: PNS, 26.6% and Vigitel, 35.8%. Conclusion: In the majority of indicators, the results were similar, especially when the questions and response options were equal. Surveys are useful for the monitoring of risk and protective factors of noncommunicable diseases and can support health promotion programs.

BACKGROUND: Intraocular inflammation is typically treated with a combination of anti-inflammatory and anti-infective drugs. Tobramycin-dexamethasone (TD) has not been associated with any serious adverse events, indicating good tolerability. OBJECTIVE: The aims of this study were the following: (1) to demonstrate noninferiority of TD compared with dexamethasone-neomycin-polymyxin (DNP) in terms of anti-inflammatory efficacy, (2) to compare the anti-inflammatory efficacy of TD and DNP with that of a "placebo" control (antibiotic without anti-inflammatory agent), and (3) to provide additional safety data on TD. METHODS: This prospective, double-masked, parallel-group study was conducted at 22 ophthalmology clinics across Europe and Brazil. Patients aged > 18 years undergoing cataract surgery were randomly assigned, in a 2:2:1 ratio, to receive tobramycin 3 mg/mL plus dexamethasone 1 mg/mL, dexamethasone 1 mg/mL plus neomycin sulfate 3500 IU/mL plus polymyxin B sulfate 6000 IU/mL, or neomycin sulfate 3500 IU/mL plus polymyxin B sulfate 7500 IU/mL plus gramicidin 20 microg/mL. All treatments were given as 1 drop instilled in the operated eye q.i.d. for 21 days. The primary efficacy end point, intraocular inflammation (determined using the sum of scores on anterior chamber cells and aqueous flare), was assessed at days 3, 8, 14, and 21 after surgery. RESULTS: A total of 271 patients were enrolled (158 women, 113 men; age range 42-90 years) (TD, 104 patients; DNP, 110 patients; and neomycin-polymyxin-gramicidin [NPG], 57 patients). Intraocular inflammation was similar in the TD and DNP groups at all time points. At days 8, 14, and 21, inflammation scores were significantly lower with TD than with NPG (all, P < 0.05). At day 8, the inflammation score was significantly lower with DNP than with NPG (P < 0.05). A greater number of patients receiving NPG experienced treatment-related ocular allergic reactions compared with patients receiving TD (P < 0.05). One patient receiving TD (1.0%) and 5 given NPG (9.0%) were withdrawn due to ocular allergic reactions. None of the patients experienced an increase in intraocular pressure > or =10 mm Hg from baseline. CONCLUSIONS: In this study of patients undergoing cataract surgery combination therapy with TD was noninferior to DNP and was well tolerated.
