          ABSTRACT

          CONTEXT AND OBJECTIVE:

          The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI).

          DESIGN AND SETTING:

          Descriptive study at Brazilian Cochrane Center.

          METHODS:

          All the published articles were evaluated according to merit assessment (content) and form assessment (performance).

          RESULTS:

          Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives.

          CONCLUSIONS:

          These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

          RESUMO

          CONTEXTO E OBJETIVO:

          A utilização de métodos científicos rigorosos tem contribuído para o desenvolvimento de artigos científicos de excelente qualidade metodológica, o que permite a promoção da sua citação, bem como o aumento do fator de impacto. Os periódicos nacionais tiveram que se adequar a alguns padrões de qualidade exigidos pelos indexadores, como por exemplo o conteúdo e o número de artigos originais publicados em cada fascículo. O objetivo foi avaliar a adequação metodológica de dois periódicos brasileiros, na área de cardiologia, indexados em várias bases de dados e disponíveis em livre acesso na Scientific Electronic Library Online (SciELO) e atualmente indexados na Web of Science (Institute for Scientific Information, ISI).

          TIPO DE ESTUDO E LOCAL:

          Estudo descritivo realizado no Centro Cochrane do Brasil.

          MÉTODO:

          Todos os artigos foram avaliados quanto ao mérito (conteúdo) e quanto à forma (desempenho).

          RESULTADO:

          Foi observada uma taxa de 96% de adequação metodológica entre os artigos avaliados, que apresentaram desenho de estudo adequado para responder o objetivo proposto.

          CONCLUSÕES:

          Esses dois periódicos brasileiros na área da cardiologia publicaram artigos metodologicamente adequados, considerando os critérios de qualidade utilizados. Assim, esses periódicos podem ser considerados para consulta e como veículos para a publicação de artigos futuros. Para análises posteriores, é essencial a aplicação de outros indicadores de atividade científica, como a bibliometria, que avalia aspectos quantitativos da produção, disseminação e uso da informação, e a cienciometria, que também considera o desenvolvimento de políticas de ciência, e que muitas vezes se sobrepõe à bibliometria.

            Cardiovascular risk in vegetarians and omnivores: a comparative study.

            Clinical and epidemiological studies have demonstrated a strong association between eating habits and chronic diseases, particularly cardiovascular events, although not all the mechanisms of action are understood. To describe and analyze the cardiovascular risk (CVR) in vegetarians and omnivores residing in Greater Vitória, State of Espírito Santo, Brazil, in the age range from 35 to 64 years. To evaluate CVR in the groups, a historical cohort study with 201 individuals was conducted. Sixty seven individuals who had been following a vegetarian diet for at least five years, and who were from Greater Vitória, as well as 134 omnivores participating in the MONICA Project/Vitória matched for socioeconomic class, gender, age and race were included. Biochemical and hemodynamic measurements were obtained in the Cardiovascular Investigation Clinic of UFES. For comparison of proportions, the chi2 test was used, and the Prevalence Ratio was calculated. The CVR was calculated using the Framingham algorithm for the group as a whole, and for separate genders. The mean age of the group was 47+/-8 years and the mean duration of vegetarianism was 19+/-10 years; the lacto-ovo vegetarian diet was followed by 73% of the vegetarians. Blood pressure, fasting plasma glucose, total cholesterol, LDL-c, and triglycerides were lower among vegetarians (p<0.001). HDL-c levels were not different between the groups. According to the Framingham algorithm, vegetarians had a lower CVR (p<0.001). Unbalanced omnivorous diet with excess animal protein and fat may be implicated, to a great extent, in the development of noncommunicable diseases and conditions, especially in the CVR.

              C-reactive protein: an inflammatory marker with prognostic value in patients with decompensated heart failure.

              Inflammation has been implicated in the pathophysiology of a series of cardiovascular diseases. C-reactive protein (CRP) is a marker of inflammation easily obtained in the emergency room. To study the prognostic value of CRP in patients admitted for acute decompensated heart failure (ADHF). A prospective cohort of 119 patients with ADHF treated in the emergency room. Mean age was 74+/-11 years and 76 (64%) of patients were male. All were New York Heart Association Functional Class III or IV. CRP was measured by nephelometry at admission. Patients were followed after hospital discharge for an average of 12+/-9.7 months and cardiovascular mortality was the outcome analyzed. There were 44 (36.9%) deaths, all from cardiovascular causes. Individuals with CRP > 3 mg/dl had higher mortality than those below this level (p=0.018). In the multivariate analysis using Cox proportional model, CRP proved to be the most important independent prognostic factor (odds ratio 0.0916 [95% CI = 0.0341 - 0.1490] for each one-unit increment in CRP). CRP is an independent cardiovascular mortality predictor in patients with ADHF, indicating that inflammation represents an important component in the pathophysiology of the disease.
