    OBJECTIVE: Verify whether a journal's impact factor is a mechanism that modifies the ethi cal requirements described in the instructions provided to authors of articles published in Brazilian medical journals. METHODS: 48 selected journals were divided into two groups: impact-factor (n = 24), and no impact-factor (n = 24). The number of ethical requirements was compared between both groups based on a specific research protocol, ranging from zero to six points, analyzing the presence of an approval by a research ethics committee; reference to the fact that the research follows the precepts of the Declaration of Helsinki and the rules of Resolution 196/96; use of an informed consent; information about the authors' conflicts of interest; and a request for registration of clinical trials in the Brazilian Clinical Trials Registry. RESULTS: The average score of the impact-factor group was significantly higher than that of the no-impact-factor group (3.12 ± 1.03 vs. 2.08 ± 1.64, p = 0.0121). When each ethical requirement was compared between the groups, there was significant difference only between the requirement of an informed consent and the disclosure of conflicts of interest (p < 0.05). CONCLUSION: The impact factor is a determinant factor on the ethics included in the instructions to authors of articles in scientific journals, showing that higher-quality journals seek better-designed articles that are conscientious at the beginning of the research.

    Literatura científica brasileira sobre transtornos do espectro autista
    (Associação Médica Brasileira, 2010-01-01) Teixeira, Maria Cristina Triguero Veloz; Mecca, Tatiana Pontrelli; Velloso, Renata De Lima; Bravo, Riviane Borghesi; Ribeiro, Sabrina Helena Bandini; Mercadante, Marcos Tomanik [UNIFESP]; Paula, Cristiane Silvestre de [UNIFESP]; Universidade Presbiteriana Mackenzie Centro de Ciências Biológicas e da Saúde Programa de Pós-Graduação em Distúrbios do Desenvolvimento; Universidade Presbiteriana Mackenzie Programa de Pós-graduação em Distúrbios do Desenvolvimento; Universidade Federal de Minas Gerais Faculdade de Medicina; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: This study is a systematic review aiming to conduct a general analysis of the scientific production covering publications of Brazilian authors about ASD in the period from 2002 to 2009. METHODS: The bibliographic search was conducted in the following scientific databases: PUBMED, SciELO, LILACS and portal CAPES, by using keywords such as autism and pervasive developmental disorders. RESULTS: A total of 93 papers were identified mainly produced by authors from tSoutheast Brazil and from public universities. Approximately one third of the papers was published in journals with a level of impact factor that ranged from 0.441 to 3.211; most of them were based on small sample sizes. Identified were 140 dissertations/theses; 82.1% were masters theses. The major research topic was related to intervention programs addressing ASD. CONCLUSION: This review shows that Brazilian researchers are interested in the ASD theme, however, a large part of this scientific production is concentrated in dissertation/masters theses and the minority of papers was published in journals with a high impact factor. Results of this systematic review suggest the need for studies with larger sample sizes which would produce greater impact and visibility in the Brazilian scientific production in the field of the ASD.
