    Apresenta um panorama da atividade de Assessoria de Imprensa no Brasil após a implantação das novas tecnologias. A partir de uma análise de como as inovações tecnológicas influenciaram na rotina de trabalho da Comunicação Social e do Jornalismo, pretende-se compreender as vantagens e desvantagens desse processo nas assessorias de imprensa do país. Para tal, será utilizado como objeto de enfoque o setor do Banco Nacional de Desenvolvimento Econômico e Social (BNDES) que atualmente é responsável pela administração dos fluxos de informações jornalísticas na mídia. A principal questão a ser tratada ao longo deste estudo consiste em uma comparação entre a realidade atual das assessorias e o período anterior à implantação das novas tecnologias. Devido ao fato de esta atividade ter sido instalada no Brasil apenas na década de 60, este estudo irá considerar somente o computador, a Internet e a videoconferência como novas tecnologias de comunicação

    Background-It remains uncertain whether acetylcysteine prevents contrast-induced acute kidney injury. Methods and Results-We randomly assigned 2308 patients undergoing an intravascular angiographic procedure with at least 1 risk factor for contrast-induced acute kidney injury (age >70 years, renal failure, diabetes mellitus, heart failure, or hypotension) to acetylcysteine 1200 mg or placebo. The study drugs were administered orally twice daily for 2 doses before and 2 doses after the procedure. The allocation was concealed (central Web-based randomization). All analysis followed the intention-to-treat principle. The incidence of contrast-induced acute kidney injury (primary end point) was 12.7% in the acetylcysteine group and 12.7% in the control group (relative risk, 1.00; 95% confidence interval, 0.81 to 1.25; P = 0.97). A combined end point of mortality or need for dialysis at 30 days was also similar in both groups (2.2% and 2.3%, respectively; hazard ratio, 0.97; 95% confidence interval, 0.56 to 1.69; P = 0.92). Consistent effects were observed in all subgroups analyzed, including those with renal impairment. Conclusions-In this large randomized trial, we found that acetylcysteine does not reduce the risk of contrast-induced acute kidney injury or other clinically relevant outcomes in at-risk patients undergoing coronary and peripheral vascular angiography.Ministério da Saúde do BrasilBrazilian Ministry of Healt
