ABSTRACT
Bibliometrics is frequently used to analyze the structural evolution of research fields, especially in biomedical areas. The present paper provides a macrostructure for scientific research on vitiligo conducted in the last fifty years using bibliometric methods. The data were retrieved from Scopus. A total 6 109 papers related to vitiligo were processed. An analysis was conducted of specialized terms based on the structure of the Medical Subject Headings (MeSH) thesaurus of the US National Library of Medicine. A structural approach was developed using term co-occurrence analysis. Hierarchical cluster analysis was used to identify the macrostructure, applying the CONCOR (CONvergence of iterated CORrelations) algorithm. Global scientific production on vitiligo was found to have increased exponentially in the last fifty years. Structural analysis revealed eight research areas divided in two blocks. On the one hand, an experimental block comprising studies on vitiligo, its relationships with cancer and other autoimmune diseases, its pathophysiology and pathogenesis; and on the other, a block including clinical studies covering various therapeutic approaches as well as the incidence and prevalence of the disease. The methodology applied constitutes a valid tool for the description and classification of biomedical knowledge domains. It also makes it possible to obtain a macrostructure which may be validated through bibliographic reviews
La bibliometría se usa frecuentemente para analizar la evolución estructural de campos de investigación, especialmente en áreas biomédicas. El presente trabajo ofrece una macroestructura de la investigación científica sobre vitiligo durante los últimos 50 años a partir de métodos bibliométricos. Los datos fueron recuperados de Scopus. Un total de 6 109 artículos relacionados con el vitiligo fueron procesados. Fueron analizados los términos especializados basados en la estructura del tesauro Medical Subject Headings (MeSH) de la Biblioteca Nacional de Medicina de los Estados Unidos. Se desarrolló un enfoque estructural a partir del análisis de la co-ocurrencia de términos. Se utilizó el análisis de agrupamientos jerárquicos para identificar la macroestructura, a partir de la aplicación del algoritmo CONCOR (CONvergencia de CORrelaciones iteradas). La producción científica mundial sobre vitiligo mostró un crecimiento exponencial durante los últimos 50 años. El análisis estructural reveló ocho áreas de investigación divididas en dos bloques temáticos. En primer lugar, un bloque experimental que agrupa los estudios sobre el vitiligo, sus relaciones con el cáncer y otras enfermedades autoinmunes, su patofisiología y su patogénesis; y en segundo lugar, un bloque de estudios clínicos que agrupa diferentes enfoques terapéuticos, así como la incidencia y prevalencia de la enfermedad. La metodología aplicada ofrece una herramienta válida para la descripción y clasificación de dominios del conocimiento biomédicos. Además, permite obtener una macroestructura que puede ser validada a partir de revisiones bibliográficas

A diversidade de anfíbios no Cerrado é ameaçada principalmente pelo aumento das atividades antrópicas. A legislação vigente exige de empreendimentos potencialmente impactantes a implantação de programas ambientais que incluem a recuperação de áreas degradadas e o estudo dos mecanismos ecológicos associados à recolonização de áreas alteradas. Os objetivos deste estudo foram: avaliar possíveis diferenças na composição de espécies em assembléias de anuros entre áreas de topografia modificada (ATM) e áreas de topografia não modificada (ATNM); e comparar a riqueza de anuros entre ATM e ATNM. Apesar do maior número de espécies registradas na ATM (28 espécies) em relação à ATNM (22 espécies), não houve diferença na riqueza quando comparamos as curvas de rarefação ou a riqueza estimada (jackknife1). Entretanto, as duas assembléias diferiram quanto às curvas de abundância relativa, especialmente quanto ao padrão das espécies mais abundantes. Localmente, a análise de co-ocorrência demonstrou que as espécies na ATM co-ocorrem menos do que o esperado ao acaso, o que indica a partilha dos ambientes para reprodução mediada por interações competitivas. A presença de corpos d'água artificiais com alta heterogeneidade estrutural, associados a fragmentos florestais em bom estado de conservação são fatores que contribuem para a manutenção de uma alta diversidade de anfíbios na área.
