Fifty years of Brazilian Dental Materials Group: scientific contributions of dental materials field evaluated by systematic review

ABSTRACT Objective A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. Material and Methods This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, IBECS, BBO, and the Cochrane Library. Additionally, the Brazilian patent database (INPI - Instituto Nacional de Propriedade Industrial) was screened in order to get an overview of Brazilian technological development in the dental materials field. Two reviewers independently analyzed the documents. Only studies and patents related to dental materials were included in this review. Data regarding the material category, dental specialty, number of documents and patents, filiation countries, and the number of citations were tabulated and analyzed in Microsoft Office Excel (Microsoft Corporation, Redmond, Washington, United States). Results A total of 115,806 studies and 53 patents were related to dental materials and were included in this review. Brazil had 8% affiliation in studies related to dental materials, and the majority of the papers published were related to dental implants (1,137 papers), synthetic resins (681 papers), dental cements (440 papers), dental alloys (392 papers) and dental adhesives (361 papers). The Brazilian technological development with patented dental materials was smaller than the scientific production. The most patented type of material was dental alloys (11 patents), followed by dental implants (8 patents) and composite resins (7 patents). Conclusions Dental materials science has had a substantial number of records, demonstrating an important presence in scientific and technological development of dentistry. In addition, it is important to approximate the relationship between academia and industry to expand the technological development in countries such as Brazil.

Cómo atraer más y mejores manuscritos para publicación en las revistas biomédicas chilenas / How to attract more and better manuscripts to be published in chilean biomedical journals

A survey was addressed to 57 editors of Chilean biomedical journals, on how to attract more and better manuscripts to their journals. Thirty seven editors (65 percent) answered this survey. According to them the main motivation of Medical Societies for editing their own journals is to improve information acquisition. To communicate an experience, followed by getting credits in their curriculum vitó, were considered by the editors as the main motivations of authors to submit papers. The most frequent deficiencies of manuscripts received are: disorganization in their presentation and bad adherence to journal's requirements for submitting manuscripts. An improvement in the relationship between author-editor-reviewer was mentioned by most of the editors, as the mechanism to be used to enhance the quality of the manuscripts. Only 14 editors (38 percent) agree in that there is a decrease in the number of original papers submitted. This decrease was attributed by most of them, to a high pressure for publishing in journals with the highest impact factor. Suggestions on how to improve the Chilean biomedical journals included: a) to professionalize editorial work and to increase meticulousness when reviewing manuscripts; b) to increase the recognition of articles published in Chilean biomedical journals, when applying for academic promotions or research grants and c) to create a national impact factor

El neumólogo y su producción científica / The pneumologist and his scientific production

Tratando de determinar cómo y cuánto escribe el neumólogo en revistas de circulación periódica tanto nacional como extranjera, analizamos la productividad científica del neumólogo en el INDEX BIBLIOMEX de 1990 a 1993, valorando tipo e estudio, institución participante y actividad profesional del primer autor. Nuestros resultados demuestran que existe una tendencia ascendente no significativa en el número de publicaciones por año; se publican predominantemente aspectos monográficos y casos clínicos, siendo la Secretaría de Salud, seguida del Instituto Mexicano del Seguro Social, los que más producen. En cuanto a la esfera profesional, se observó que el neumólogo y no neumólogo comparten prácticamente la misma frecuencia; sin ambargo, en la esfera pediátrica, la relación pediatra/neumólogo pediatra es de 5:1. Se concluye que es necesario que el neumólogo dedique más tiempo a publicar sus experiencias, por ser el que debe dar las pautas de conducta en cuanto a la patología respiratoria se refiere

La medicina en los gremios médicos en el siglo XX

Se analiza la evolución social de la práctica médica en Colombia y su influjo sobre el nacimiento de los gremios y asociaciones médicas; los efectos producidos por los cambios demográficos, por la fundación de nuevas escuelas de medicina; la introducción de la seguridad social y las modificaciones y reformas del Sistema Nacional de Salud. Así mismo, se analiza la evolución de los sistemas y subsistemas de prestación de servicios de salud vigentes, y los cambios sociales y laborales que lleva consigo. Aunque la profesión médica no constituye un grupo social o laboralmente homogéneo, se pueden desarrollar objetivos comunes en las áreas de convergencia, encaminados hacia programas que mejoren la salud de los colombianos y las condiciones laborales de los profesionales
