Citing of national articles: the (de)valuation of brazilian journals

OBJECTIVE To evaluate whether there is a preference for foreign periodicals over Brazilian one. METHODS We evaluated all references of articles published in the years 2011 and 2007 in the journals Acta Cirúrgica Brasileira, Arquivos Brasileiros de Cirurgia Digestiva and the Journal of the Brazilian College of Surgeons, verifying the quantity of papers from Brazilian and foreign publications. RESULTS We analyzed a total of 7,343 references arranged in 348 articles in those three journals; of these, 856 (11.65%) were from Brazilian journals. There was no difference between the three magazines, nor between the two periods. One hundred and eleven (31.9%) articles did not cite any Brazilian journal article and 36 (10.34%) cited Brazilian articles more than foreign ones. CONCLUSION There is need for the Brazilian researcher to appreciate more the Brazilian journals, increasing citation from Brazil, without a scientific xenophobia.

Copaiba oil effect under different pathways in mice subjected to sepsis.

PURPOSE To evaluate the effects of copaiba oil administered by different routes on survival of mices subjected to cecal ligation and puncture. METHODS Thirty two mice were distributed into four study groups (N=8): Sham group: normal standard animals; CONTROL GROUP submitted a cecal ligation and puncture (CLP); Gavage group: submitted a CLP, and treat with copaiba oil by gavage; and Subcutaneous group: submitted a CLP, and treat with copaiba oil by subcutaneous injection. After the death of the histological analysis were performed. The Kaplan-Meier curves of surviving time were realized. RESULTS All animals that received copaiba, regardless of the route used, survived longer when compared to the control group (p<0.0001), whereas the survival time ranged from 20 hours for the control group up to 32 hours for the animals of gavage group and 52 for subcutaneous group. The animals that received gavage copaiba lived about and about 20 hours unless the subcutaneous group (p=0.0042). There was no statistical difference when compared the intensity of inflammatory response (p>0.05) CONCLUSION: Prophylactic subcutaneous administration of copaiba in mice subjected to severe sepsis by cecal ligation and puncture, resulted in a survival time higher than non-use or use of this oil by gavage.

Immunohistochemistry of the uterine cervix of rats bearing the Walker 256 tumor treated with copaiba balsam

PURPOSE To investigate the immunohistochemistry of the uterine cervix of 20 Wistar rats (Rattus norvegicus) bearing the Walker 256 tumor, treated with copaiba oil (Copaifera officinalis). METHODS The animals were grouped into four subgroups, with five rats each: the GCT and GCopT received distilled water and topically copaiba, respectively, while the GCG and GCopG received distilled water and copaiba by gavage, respectively. The substances were administered for nine days. On the 12th day, after euthanasia, the tumor pieces were sent to the identification of T CD4+, T CD8+ and Natural Killer cells. RESULTS It was found that the pattern of expression for specific markers of phenotypes of cells involved in tumor immune response was similar in all groups, regardless the administration way of copaiba oil (topical or gavage). CONCLUSION Copaiba balsam, administered either topically or by gavage, did not alter the pattern of tumor immune response in rats bearing Walker 256 Tumor.

Evaluation of the key words used in articles of the Acta Cirurgica Brasileira from 1997 to 2012

PURPOSE To evaluate the key words used in Acta Cirurgica Brasileira from 1997 to 2012. METHODS All the key words of all articles published in regular issues between 1997 and 2012 were analyzed, ensuring that these key words were in the MeSH database (Medical Subjects Headings) and the most used subject headings and most wrong repeated key words were ranked. RESULTS > 4230 key words used in 990 articles were analyzed. Only 579 key words (13.68%) were not in the MeSH database, considering that there was a statistically significant decrease over the years (p<0.001). The three most used key words were Rats, Dogs and Wound healing. Among the wrong ones, the key words were Adhesions, Experimental surgery and Anatomosis. CONCLUSION There was a gradual improvement in the amount of key words used that belonged to the MeSH database, and there were 618 articles (62.42%) with all key words correct.

A cirurgia experimental e sua relação com a universidade: relato de experiência

The laboratory of experimental surgery represents one of the key points for the university, especially in the biomedical area. This focuses on the universitys tripod of primary structure that are teaching, research and extension, which are essential for formation of humanistic and practice of a good doctor that is based, first of all, on scientific evidence and critical knowledge. The importance of a laboratory of experimental surgery centers for medical education was regulated from the new curriculum guidelines of the Ministério da Educação e Cultura, establishing a mandatory laboratory within college centers. Therefore, it is of great importance to the contribution of the laboratories of experimental surgery in the curriculum, both in the discipline of surgical technics and experimental surgery, and an incentive for basic research. Thus, the study presents the experience of 15 years of the Laboratory of Experimental Surgery from Universidade do Estado do Pará, with the goal show the importance of this to medical graduation and the university.

Dominance of foreign citations in Brazilian orthopedics journals

Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often.

Referências de periódicos médicos brasileiros em publicações nacionais

OBJECTIVE To assess whether there is a preference for international journal citation to the detriment of national ones in ten Brazilian medical journals, in two different periods. METHODS All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. RESULTS A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. CONCLUSION Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles.

Influence of oophorectomy on glycemia and lipidogram

PURPOSE To verify the influence of oophorectomy on lipidogram and glycemia. METHODS Fifty six female rats were divided into the following 7 groups (n = 8): group 1 - sham group, group 2 - oophorectomy 30 days, group 3 - oophorectomy 35 days, group 4 - oophorectomy 40 days, group 5 - oophorectomy 45 days, group 6 - oophorectomy 70 days, group 7 - oophorectomy 55 days. Animals were following by number of days according the group. Was evaluated the serum levels of glucose and lipid profile. RESULTS The oophorectomized rats presented higher glycemia. Groups 3, 4, 6 and 7 had a higher glycemia and LDL levels (except for group 6) and groups 6 and 7 had lowest levels of HDL. Group 7 had highest level of VLDL than oophorectomy groups. There was no difference in triglycerides levels. CONCLUSION Oophorectomy was related to dyslipidemia and insulin resistance, mainly after 50th days.

Citations of Brazilian physical therapy journals in national publications

Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years.
