Revisão por pares na Revista Brasileira de Educação Especial

O artigo discute algumas questões relativas ao procedimento de revisão por pares na avaliação de originais submetidos a um periódico. Essa avaliação é aceita como necessária para assegurar a qualidade científica de artigos publicados, já que a integridade da literatura especializada é considerada essencial para o desenvolvimento da ciência. Entretanto, há críticas à revisão por pares, incluindo o longo tempo decorrido entre a entrega dos originais e a publicação, o tempo e a energia despendidos pelos autores e revisores, a subjetividade na avaliação e outros problemas que podem introduzir vieses na área. A Revista Brasileira de Educação Especial, que adota a avaliação cega por pares, tem-se mostrado relativamente versátil. O tempo médio entre o recebimento dos originais e o aceite final, depois de passar pela revisão por pares e conseqüente ajuste por parte dos autores, é de cerca de cinco meses e meio. Na literatura especializada, encontram-se sugestões como a eliminação de avaliação e publicação de todos os textos submetidos, em meios eletrônicos, menos onerosos e mais versáteis, deixando que os próprios leitores façam a sua avaliação. A análise procedida conclui que a revisão por pares é necessária. Aponta a necessidade de se realizarem discussões sobre a própria avaliação, para que se desenvolvam procedimentos mais eficientes de controle de qualidade das publicações. Sugere que a avaliação efetiva é feita pela própria comunidade acadêmica, após a publicação, mediante reconhecimento coletivo do valor científico da publicação, na forma de impacto que pode causar sobre novas investigações e construção do conhecimento na área.

Marxismo, a alienação e o tempo histórico da barbárie social do capital

O objetivo do ensaio é expor a alienação/estranhamento como o problema crucial do nosso tempo histórico, buscando salientar os significados do conceito de autotranscendência positiva da alienação, considerada por István Meszáros, como sendo o eixo da reflexão marxiana nos Manuscritos econômico-filosóficos. Para tanto, discorre sobre o novo registro histórico da Aufhebung nas condições da crise estrutural do capital e a vigência do capitalismo global como capitalismo manipulatório. Aborda a centralidade ontológica da problemática da vida cotidiana e o estranhamento na perspectiva da crítica radical do trabalho. Finalmente, coloca elementos para refletir, na perspectiva do marxismo radical, sobre a transição como sendo o problema de produção dos sujeitos humanos, capazes da autotranscendência positiva da alienação.

Análise dos aspectos éticos da pesquisa em seres humanos contidos nas Instruções aos Autores de 139 revistas científicas brasileiras

OBJETIVO: Estudar as normas relativas à ética da pesquisa em seres humanos contidas nas Instruções aos Autores de revistas científicas brasileiras. MATERIAL E MÉTODOS: As Instruções aos Autores de 139 revistas científicas brasileiras das áreas de medicina, biomedicina, enfermagem, odontologia e ciências gerais foram analisadas com relação às suas recomendações sobre os aspectos éticos. RESULTADOS: Das 139 revistas estudadas, 110 (79,1%) não fazem referências aos aspectos éticos; 17 (12,2%) exigem aprovação prévia pela Comissão de Ética; três (2,1%) fazem referência à Declaração de Helsinque; uma (0,7%) recomenda adotar o consentimento esclarecido; cinco (3,5%) seguem orientações dos requisitos uniformes para manuscritos submetidos a revistas biomédicas e três (2,1%) seguem princípios, normas e padrões éticos não especificados. Nas 29 revistas que fazem referências à ética, as exigências são solicitadas sob as seguintes formas: 15 (51,7%) exigem a inclusão da informação no texto do artigo; duas (6,8%) pedem carta assinada pelos autores; uma (3,4%) solicita cópia da autorização da Comissão de Ética; uma (3,4%) afirma supor que o autor cumpriu as exigências e dez (34,4%) não fazem qualquer referência específica. CONCLUSÕES: Os resultados do estudo indicam que na maioria das revistas científicas brasileiras há pouca preocupação em relação aos aspectos éticos da pesquisa em seres humanos, contidas nas Instruções aos Autores. Nas revistas que fazem referência aos aspectos éticos, as exigências são muito variáveis.

Produção científica publicada nos Anais Brasileiros de Dermatologia (2003-2007)

BACKGROUND - The scientific production of dermatology is not very known and studied in quantitative and qualitative aspects in Brazil.OBJECTIVE - To study the characteristics of the Brazilian scientific production published on the Anais Brasileiros de Dermatologia from 2003 to 2007.METHODS - A transversal study of articles published on the clinical, epidemiological, laboratory and therapeutic investigation, - case report and 'communication sections of the Anais Brasileiros de Dermatologia, from 2003 to 2007, were reviewed. The variables studied were: the dermatological subspecialty focused, methodological analysis used; diseases or disorders investigated and the understanding of authors related to the communication section.RESULTS - Among investigational manuscripts, clinical studies prevailed (60.3%), those with surgical or cosmetic interest accounted for 13%. Descriptive and observational studies were the most common (81.9%), particularly the case series (50%). Infectious (33.6%) and inflammatory disease (28.6%.) was the subject of investigation or case report, respectively, Case report was the most common subject on the communication section.CONCLUSION - Descriptive methods were predominant among the research articles published in the studied period. More sophisticated and elaborated methods were uncommon. Research designs and critical analysis of the scientific literature must be part of the curriculum of the graduate and residency programs in dermatology.

Analysis of Abstracts Presented at the Prosthodontic Research Section of IADR General Sessions 2004-2005: Demographics, Publication Rates, and Factors Contributing to Publication

Purpose: The purposes of this study were to describe the demographics of abstracts presented at the prosthodontics section of IADR General Sessions from 2004 to 2005, evaluate the publication rate of abstracts, and analyze the relationship between variables in abstracts and publication.Materials and Methods: Prosthodontics research section abstracts from the IADR General Session in 2004 and 2005 were evaluated for: number of authors, presentation type, origin, affiliation, topic, study design, statistics, study outcome, and funding. The publication rate was calculated following a PubMed search. The journal of publication, year of publication, and the length of time before publication were analyzed. Descriptive statistics were used for the data analysis; the relationships between presentation type, study design, study outcome, statistics, funding, and publication were analyzed using logistic regression (alpha = 0.05).Results: From 346 abstracts, 37.0% were published. For oral presentations, 40.7% were published; 35.8% of poster presentations were published. The mean duration before publicationwas 26.4months. North America had themost abstracts, and Europe had the most publications. Fixed prosthodontic research had the highest number and proportion for publication. A significant association with publication was noted for neutral study outcomes (p = 0.018), studies with funding (p = 0.035), and abstracts from Europe (p = 0.001).Conclusions: The majority of abstracts from the prosthodontics research section of IADR General Sessions from 2004 and 2005 remain unpublished. A significant association for publication was noted with neutral outcomes, funding, and abstracts from Europe.

Authorship, Collaboration, and Funding Trends in Implantology Literature: Analysis of Five Journals From 2005 to 2009

Purpose: To identify the trend of authorship in dental implant by exploring the prevalence of coauthored articles and to investigate the collaboration efforts, trends in funding involved in original articles, and their relationships. Materials: Articles published in the Clinical Oral Implants Research, International Journal of Oral & Maxillofacial Implants, Clinical Implant Dentistry and Related Research, Implant Dentistry, and Journal of Oral Implantology from 2005 to 2009 were reviewed. Nonoriginal articles were excluded. For each included articles, number of authors, collaboration efforts, and extramural funding were recorded. Descriptive and analytical statistics (alpha = 0.05), including logistic regression analysis and chi(2) test, were used. Results: From a total of 2085 articles, 1503 met the inclusion criteria. Publications with 5 or more authors increased over time (P = 0.813). The amount of collaboration among different disciplines, institutions, and countries all increased. The greatest increase of collaboration was seen among institutions (P = 0.09). Non-funding studies decreased over time (P = 0.031). There was a strong association between collaboration and funding for the manuscripts during the years studied (OR, 1.5). Conclusion: The number of authors per articles and collaborative studies increased over time in implant-related journals. Collaborative studies were more likely to be funded.

Factors Influencing Publication Rates of Abstracts Presented at the ADEA Annual Session & Exhibition

Factors related to the path of abstracts from presentation at a conference to publication as a full article have been analyzed in the medical field, but only a few studies have been performed in dentistry. This study investigated the rate of publication of articles based on abstracts presented at the American Dental Education Association (ADEA) Annual Session & Exhibition in 2002 and 2003 and the time lag to publication. This study also aimed to characterize the abstracts and subsequent articles and determine if there were any significant factors related to expansion of an abstract into a full manuscript. A total of 370 abstracts met the inclusion criteria and were examined for this study. Subsequent published articles were located using a standard PubMed search. Descriptive statistics and bivariate analyses were used to analyze the data collected (alpha=0.05). Results suggest that there was a low (19 percent) publication rate for articles based on abstracts presented at the meetings studied. The median time between abstract presentation and article publication was ten months. Factors that showed significant correlation to likelihood of article publication were multiple affiliations, presence of analytical statistics, and, to a lesser extent, funding. We suggest that presenters at these meetings should expand their abstracts into full manuscripts and seek to publish them in peer-reviewed journals for the benefit of the profession.

A formação humana na perspectiva histórico-ontológica

O tema da formação humana está no centro da filosofia da educação, cujo objeto é precisamente o processo de promoção humana levado a efeito pela educação. A partir da vigilância crítica, própria da filosofia, o texto esboça uma fenomenologia da época atual, constatando que as ideias atualmente hegemônicas na educação se centram na crítica à razão e às noções de verdade e de objetividade. A esse neopragmatismo que, na tentativa de opor-se à metafísica, acaba por ser profundamente metafísico reduzindo tudo à linguagem, os autores contrapõem o pensamento de Marx como uma filosofia historicizadora em que estão em causa não os sujeitos abstratos, mas os indivíduos reais, sujeitos históricos que se constituem como síntese de relações sociais. Para tanto, recorre-se à reflexão histórico-ontológica sobre a formação humana contida nos Manuscritos econômico-filosóficos de 1844, de Marx. O artigo conclui com a defesa da tese de que o acesso aos clássicos é condição necessária para a formação humana.

Variable influence of ferric and cupric ions on Saccharomyces cerevisiae strains used in asymmetric organic synthesis.

Fe (III) and Cu (II) each at 50 mu M in four commercial strains of Saccharomyces cerevisiae induced an increase of NAD(P)(+) reduction in one strain (Turkish), but two others (Chilean and Brazilian), the presence of Fe(III) and/or Cu(II) diminished NAD(P)(+) reduction presumably due to free radicals formation inside these living cells. Suprisingly, in the American strain, Fe(III) induced a decrease and Cu (II) an increase of NAD(P)(+) reduction.

Das plantas medicinais aos fitofármacos

The plants, since the antiquity, have been a resource within reach of the human being. Along millenniums, the man empirically deepened its knowledge for the improvement in the alimentation and cure conditions of its illnesses, demonstrating a narrow relation between plant use and its own evolution. A lot of people described the herbs utilization like medication form in their records and manuscripts, but many centuries have been passed until the true power of the plants was recognized. The great discoveries of the active plants principles only were possible after technological advances for the isolation and structural elucidation. Several active substances with pharmacological activity, many times indicated by the popular use, were going proved scientifically. Nowadays, the man still seeks solutions for several diseases and health problems and maybe the plants can contribute of more significant way for resolve them.

Evaluación del impacto de una intervención educativa en atención farmacéutica y farmacia clínica

Introduction: The World Health Organization considers pharmaceutical care (PC) of fundamental importance for the patient and the community. Its exercise requires knowledge and skills, which can be acquired in academic and/or continuing educations, credited for effectiveness and impact evaluation. However, few manuscripts in the literature have showed the contribution of the educational interventions on the knowledge, skill and attitude of students and professionals who participate in scientifi c events related to PC. Objective: To evaluate the impact of an educational intervention (EI), and its degree of satisfaction, to pharmacists and pharmacy students. Method: A quasi-experimental study was performed, through an extension course with 40 hours of lectures approaching issues related to PC and clinical pharmacy (CP). Participants answered a survey which was handed out before and after the EI. The statistic tests of Sinais and Mann-Whitney were applied to evaluate the EI signifi cance. Results: Participants (n= 49) were mostly (n= 34) students and performing activities related to PC and CP (n= 20). Statistics differences, before and after the EI, were found in the scores of knowledge, skill and attitude (p <0.001). The evaluated item which showed the most improvement was the last one. Most (n= 30) had exceeded or met their expectations (n= 19). Conclusions: The analysis of the data led us to conclude that an EI of 40 h/week about knowledge, skill and attitude in PC using traditional methods, improves knowledge and problem-solving skills of participants. ©2012 Ediciones Mayo, S.A.

Intervenções farmacêuticas na atenção à saúde mental: Uma revisão

Uma revisão dirigida foi realizada nas bases de dados IBECS, LILACS e MEDLINE, até fevereiro/2011, para identificar intervenções farmacêuticas (IF) na atenção farmacêutica em saúde mental e os seus resultados. Para a busca utilizaram-se os descritores em saúde: Pharmaceutical Care, Pharmaceutical Services, Medication Adherence, Pharmacists, Mental Health, Mental Health Services, Mental Health Assistance, Community Mental Health Services, Mentally Ill Persons andMental Disorders. Identificaram-se 1686 publicações, das quais 21 contemplaram os critérios de inclusão. Após exploração do material, apenas cinco estudos tratavam-se de IF. Todos foram conduzidos no nível secundário de atenção, com abordagem individual, por meio do acompanhamento da terapia (3), intervenção educativa por cartas a médicos e pacientes (1), aconselhamento farmacêutico presencial e remoto e inserção de terapia com sistema transdérmico de nicotina (1). Os resultados, tais como promoção da adesão e resolução de problemas relacionados a medicamentos foram positivos para a terapêutica. No entanto, é necessário que as IF monitorem os parâmetros clínicos, as mudanças de hábitos, a melhora na qualidade de vida e os aspectos farmacoeconômicos a fim de avaliar os seus impactos. Palavras-chave:Atenção Farmacêutica. Assistência Farmacêutica. Adesão à Medicação. Farmacêuticos. Saúde Mental. ABSTRACT Pharmaceutical interventions in mental health services: a review A directed review was performed in IBECS, LILACS and MEDLINE databases, until February/2011, in order to identify the studies which developed pharmaceutical interventions (PI) in pharmaceutical care in mental health services and estimated their results. The search was carried out using the follow health science descriptors: Pharmaceutical Care, Pharmaceutical Services, Medication Adherence, Pharmacists, Mental Health, Mental Health Services, Mental Health Assistance, Community Mental Health Services, Mentally Ill Persons andMental Disorders. It was identified 1686 manuscripts, of whose 21 contemplated the inclusion criteria. After the content analysis of the eligible manuscripts, only five developed PI. All of them were conducted in the second level of health care, with individual approach, through: therapy follow-up (3), educational interventions by letters to physicians and patients (1), presence or remote pharmaceutical counseling and inclusion of therapy with nicotine transdermal patch (1). The data, such as adherence promotion and solving drug related problems, were positive for the therapeutic. However, it is necessary that the PI monitor the clinical parameters, the habit changes, the improvement in the quality of life and the pharmacoeconomic aspects, in order to assess their impacts.
