RESUMEN Propósito Elaborar y validar una tarea experimental de memoria episódica verbal en español. Método Se elaboraron seis bloques de codificación: tres profundos y tres superficiales, cado uno con distintas demandas de esfuerzo cognitivo. Los bloques fueron revisados por cuatro jueces expertos y examinados en una aplicación piloto. Se evaluó la concordancia respecto a si la tarea permitía manipular combinadamente el nivel de procesamiento y el esfuerzo cognitivo durante la codificación incidental de palabras, así como la claridad de las instrucciones, ejemplos y dinámica de trabajo. Resultados Variables como la disponibilidad léxica, metría y fuerza de asociación fueron útiles para diferenciar el esfuerzo cognitivo entre cada bloque. Los jueces concordaron que los bloques de procesamiento admiten una manipulación combinada del nivel de procesamiento y esfuerzo cognitivo y que las instrucciones son precisas. Luego del pilotaje, los participantes concordaron que las instrucciones, ejemplos y forma de trabajo eran fácil de comprender y realizar. Conclusión Los resultados proporcionan evidencia de validez relacionada con el contenido para la tarea experimental propuesta, transformándose con ello en una alternativa viable de considerar en investigaciones orientadas a identificar factores ambientales que contribuyan a compensar los defectos que muestra la memoria episódica con la edad.

ABSTRACT Purpose To develop and validate an experimental verbal episodic memory task in Spanish. Methods Six encoding blocks were elaborated, three deep and three superficial, each one with different demands of cognitive effort. The blocks were reviewed by four expert judges and tested in a pilot application. The agreement was assessed on whether the task allowed combined processing level and cognitive effort to be manipulated during incidental encoding of words, as well as clarity of instructions, examples, and workflow. Results Variables such as lexical availability, metrics, and strength of association were useful to differentiate the cognitive effort between each block. The judges agreed that the processing blocks allowed a combined manipulation of the level of processing and cognitive effort and that the instructions are precise. After the pilot, the participants agreed that the instructions, examples, and way of working were easy to understand and perform. Conclusion The results provide evidence of validity related to the content for the proposed experimental task, thus becoming a viable alternative to consider in research aimed at identifying environmental factors that contribute to compensating the defects shown by episodic memory with age.

RESUMEN

OBJECTIVES: Automated systems for information extraction are becoming very useful due to the enormous scale of the existing literature and the increasing number of scientific articles published worldwide in the field of medicine. We aimed to develop an accessible method using the open-source platform KNIME to perform text mining (TM) on indexed publications. Material from scientific publications in the field of life sciences was obtained and integrated by mining information on hemolytic uremic syndrome (HUS) as a case study. METHODS: Text retrieved from Europe PubMed Central (PMC) was processed using specific KNIME nodes. The results were presented in the form of tables or graphical representations. Data could also be compared with those from other sources. RESULTS: By applying TM to the scientific literature on HUS as a case study, and by selecting various fields from scientific articles, it was possible to obtain a list of individual authors of publications, build bags of words and study their frequency and temporal use, discriminate topics (HUS vs. atypical HUS) in an unsupervised manner, and cross-reference information with a list of FDA-approved drugs. CONCLUSIONS: Following the instructions in the tutorial, researchers without programming skills can successfully perform TM on the indexed scientific literature. This methodology, using KNIME, could become a useful tool for performing statistics, analyzing behaviors, following trends, and making forecast related to medical issues. The advantages of TM using KNIME include enabling the integration of scientific information, helping to carry out reviews, and optimizing the management of resources dedicated to basic and clinical research.

RESUMEN

ABSTRACT OBJECTIVE To compare the death counts from three sources of information on mortality available in Brazil in 2010, the Mortality Information System (SIM - Sistema de Informações sobre Mortalidade ), Civil Registration Statistic System (RC - Sistema de Estatísticas de Resgistro Civil ), and the 2010 Demographic Census at various geographical levels, and to confirm the association between municipal socioeconomic characteristics and the source which showed the highest death count. METHODS This is a descriptive and comparative study of raw data on deaths in the SIM, RC and 2010 Census databases, the latter held in Brazilian states and municipalities between August 2009 and July 2010. The percentage of municipalities was confirmed by the database showing the highest death count. The association between the source of the highest death count and socioeconomic indicators - the Índice de Privação Brasileiro (IBP - Brazilian Deprivation Index) and Índice de Desenvolvimento Humano Municipal (IHDM - Municipal Human Development Index) - was performed by bivariate choropleth and Moran Local Index of Spatial Association (LISA) cluster maps. RESULTS Confirmed that the SIM is the database with the highest number of deaths counted for all Brazilian macroregions, except the North, in which the highest coverage was from the 2010 Census. Based on the indicators proposed, in general, the Census showed a higher coverage of deaths than the SIM and the RC in the most deprived (highest IBP values) and less developed municipalities (lowest IDHM values) in the country. CONCLUSION The results highlight regional inequalities in how the databases chosen for this study cover death records, and the importance of maintaining the issue of mortality on the basic census questionnaire.

RESUMEN

The objective of this article is to describe the characteristics of addressing the linkage of administrative databases and the uses of such linkages in public health research, and also to discuss the opportunities and challenges for implementation in Ecuador. The linkage of databases makes it possible to integrate a person's data that may be scattered across different subsectors such as health, education, justice, immigration, and social programs. It also facilitates research that can inform more efficient management of social and health programs and policies. The main advantages of using linked databases are: diversity of data, population coverage, stability over time, and lower cost in comparison to primary data collection. Despite the availability of tools to process, link, and analyze large data sets, there has been minimal use of this approach in Latin American countries. Ecuador is well positioned to implement this approach, due to compulsory use of a unique ID in health services delivery, which permits linkages with other national information systems. However, the country faces several cultural, technical, ethical, legal, and political challenges. To take advantage of its potential, Ecuador needs to develop a data governance strategy that includes standards for data access and data use, as well as mechanisms for data control and quality, greater investment in professional training in data use both within and beyond the health sector, and collaborations between government entities, universities, and civil society organizations.

Os objetivos deste artigo são descrever as características do método de vinculação de bancos de dados administrativos e sua utilização em pesquisa em saúde pública e examinar o potencial e os desafios para sua implementação no Equador. A vinculação de bancos de dados possibilita integrar dados de uma mesma pessoa dispersos em subsetores diversos como saúde, educação, justiça, imigração e programas sociais e realizar pesquisas para subsidiar a gestão mais eficiente de programas e políticas sociais e de saúde. Entre as principais vantagens de utilizar bancos de dados vinculados estão diversidade dos dados, cobertura populacional, estabilidade temporal e custo menor em comparação à coleta de dados primários. Apesar de existirem ferramentas para processar, vincular e analisar grandes conjuntos de dados, a utilização deste método é mínima nos países da América Latina. O Equador possui um grande potencial para beneficiar-se com este método devido à obrigatoriedade do uso de um identificador único na prestação de serviços de saúde, o que permite a vinculação com outros sistemas de informação nacionais, mas enfrenta uma série de desafios técnicos, éticos-legais, culturais e políticos. Para aproveitá-lo, o país precisa elaborar uma estratégia de governança de dados contendo um conjunto de normas para o acesso e a utilização simultâneos com mecanismos de controle e qualidade dos dados, maior investimento em formação profissional no uso dos dados dentro e fora da área da saúde e colaboração entre entidades governamentais, universidades e organizações da sociedade civil.

RESUMEN

RESUMO: Objetivo: Estimar o grau de concordância e validade dos diagnósticos de neoplasias malignas relacionadas à exposição ao asbesto registrados no Sistema de Informação Hospitalar do Sistema Único de Saúde (SIH/SUS), em comparação aos Registros Hospitalares de Câncer do Estado de São Paulo (RHC/SP). Métodos: Óbitos com registros de neoplasias malignas associadas ao asbesto foram identificados e extraídos do SIH/SUS entre 2007 e 2014. Óbitos nos casos de câncer registrados na base do RHC/SP foram extraídos para o mesmo período. Essas bases foram unidas pelos mesmos indivíduos empregando-se o software Link Plus. Um único diagnóstico codificado pela CID-O3 ou CID-10 selecionado de cada sistema foi analisado. A proporção de concordância e a sensibilidade, especificidade e valores preditivos foram estimados. Resultados: Encontraram-se 19.458 pares com registros nas duas bases. A proporção de concordância foi elevada, variando de 92,4% para a localização primária desconhecida a 99,7% para o câncer de pleura. O índice Kappa variou de 0,05 (IC95% 0,04 - 0,07) para o câncer de pleura a 0,85 (IC95% 0,84 - 0,87) para o câncer de pulmão. A menor sensibilidade foi de 0,08 (IC95% 0,01 - 0,25), para o câncer de pleura, e a maior de 0,90 (IC95% 0,90 - 0,91), para o câncer de pulmão. Conclusão: Diagnósticos de neoplasias malignas associadas ao asbesto alcançaram maiores níveis de concordância e validade quando comuns. Os diagnósticos mais raros apresentaram baixa acurácia no SIH/SUS.

ABSTRACT: Objective: To estimate the degree of agreement and validity of diagnoses of asbestos-related malignant neoplasms registered in the Hospital Information System of the Brazilian Unified Health System (SIH/SUS), in comparison to the Hospital Cancer Registries of the State of São Paulo (HCR/SP). Methods: Deaths with records of malignant neoplasms associated with asbestos were identified and extracted from SIH/SUS between 2007 and 2014. Deaths in cases registered in the HCR/SP were extracted for the same period. The databases were linked using software Link Plus. A single ICD-10-coded diagnosis selected from each system was analyzed. The proportion of agreement, and the sensitivity, specificity and predictive values were estimated. Results: 19,458 pairs were found with records in both bases. The proportion of agreement was high, ranging from 92.4% for the unknown primary site, to 99.7% for cancer of the pleura. The Kappa Index ranged from 0.05 (95%CI 0.04 - 0.07) for cancer of the pleura to 0.85 (95%CI 0.84 - 0.87) for lung cancer. Sensitivity varied from 0.08 (95%CI 0.01 - 0.25) for cancer of the pleura, to 0.90 (95%CI 0.90 - 0.91) for lung cancer. Conclusion: Diagnosis of asbestos-related malignancies reached higher levels of agreement and validity when common. Rare diagnoses showed low accuracy in SIH/SUS.

RESUMEN

RESUMEN Los objetivos de este artículo son describir las características del abordaje de vinculación de bases de datos administrativos y sus usos en investigación en salud pública, y discutir las potencialidades y retos para su implementación en Ecuador. La vinculación de bases de datos permite integrar datos de una misma persona dispersos en distintos subsectores como salud, educación, justicia, inmigración y programas sociales, y posibilita investigaciones que informen una gestión más eficiente de programas y políticas sociales y de salud. Las principales ventajas del uso de bases de datos relacionadas son la diversidad de datos, la cobertura poblacional, la estabilidad temporal y el costo menor en comparación con la recolección de datos primarios. A pesar de la disponibilidad de herramientas para procesar, vincular y analizar grandes conjuntos de datos, el uso de este abordaje es mínimo en los países de América Latina. Ecuador tiene un alto potencial para explotar este abordaje, debido a la obligatoriedad del uso de un identificador único en la prestación de servicios de salud, que permite la vinculación con otros sistemas de información nacionales. Sin embargo, enfrenta una serie de retos técnicos, ético-legales, culturales y políticos. Para aprovechar su potencial, Ecuador necesita desarrollar una estrategia de gobernanza de datos que incluya normativas de acceso y uso de los datos, de manera simultánea con mecanismos de control y calidad de los datos, una mayor inversión en formación profesional en el uso de los datos dentro y fuera del sector salud, y colaboraciones entre entidades gubernamentales, universidades y organizaciones de la sociedad civil.

RESUMEN

INTRODUCTION: One of the factors to influence abandoning breastfeeding is mothers' use of medications. The www.e-lactancia.org website is a reliable source in Spanish and English for online free-access information about the compatibility of medications with breastfeeding. The aim of this study was to analyse the search profiles, and groups and products, searched the most on this website. MATERIALS AND METHODS: A retrospective and descriptive study of the e-lactancia.org website during 2014-2018. Google Analytics was used for data collection. The following variables were analysed: number of users and queries; professional profile; country; language; users' and groups' access modes/devices; most searched products. RESULTS: We found 16,821.559 users and 63,783.866 pages. Of users, 62.7 % were "mother/father", and 31.9 % were health professionals. Visits came mostly from: Spain (25.86 %); Mexico (16.87 %); Argentina (7.99 %); Chile (7.31 %). The preferred access mode and device were organic searches (62.1 %) and mobile phones (73.4 %), respectively. Phytotherapy (14.4 %), antibacterial agents (12.3 %) and NSAIDs (12.3 %) were the most searched groups, and ibuprofen (6.25 %) was the most popular product. CONCLUSION: Users and consultations in e-lactation increased significantly during the study period. Mothers/fathers were the main website users, followed by health professionals. The main consulted groups were antibacterial agents, NSAIDs and systemic phytotherapy. Ibuprofen, paracetamol and amoxicillin stood out as the most consulted products. These results revealed increase Internet resources use to solve parents and health professionals' breastfeeding doubts. Future research should study how users (parents, health professionals) interact with this information.

RESUMEN

Background: Free-text imposes a challenge in health data analysis since the lack of structure makes the extraction and integration of information difficult, particularly in the case of massive data. An appropriate machine-interpretation of electronic health records in Chile can unleash knowledge contained in large volumes of clinical texts, expanding clinical management and national research capabilities. Aim: To illustrate the use of a weighted frequency algorithm to find keywords. This finding was carried out in the diagnostic suspicion field of the Chilean specialty consultation waiting list, for diseases not covered by the Chilean Explicit Health Guarantees plan. Material and Methods: The waiting lists for a first specialty consultation for the period 2008-2018 were obtained from 17 out of 29 Chilean health services, and total of 2,592,925 diagnostic suspicions were identified. A natural language processing technique called Term Frequency-Inverse Document Frequency was used for the retrieval of diagnostic suspicion keywords. Results: For each specialty, four key words with the highest weighted frequency were determined. Word clouds showing words weighted by their importance were created to obtain a visual representation. These are available at cimt.uchile.cl/lechile/. Conclusions: The algorithm allowed to summarize unstructured clinical free-text data, improving its usefulness and accessibility.

RESUMEN

OBJECTIVES: To evaluate the pattern of internet use and factors that facilitate or dissuade its use among nursing students from a university in Urmia, Iran. METHODS: A cross-sectional, descriptive study was conducted with 162 nursing students selected through simple random sampling. RESULTS: The findings indicated that 49.1% of the students used the internet from 15 to 60 min per day. The principal use of the internet was to search for scientific content in the Web. Factors that facilitated internet use were "ease of use" and "Access to experts to solve problems and answer questions", while the dissuasive factors were "lack of concentration", "cost of internet services", and preference for information provided by professors or available directly in textbooks. Internet use by the students was related with the use of this tool in classroom activities and with English fluency. CONCLUSIONS: Students have an internet use pattern aimed at self-study that should be strengthened with knowledge of English, assignments online, familiarization with the use of electronic databases, and other strategies to motivate them to use this technology with greater frequency.

RESUMEN

INTRODUCTION: Clinical trials are the gold standard for testing the efficacy and safety of interventions. On their own they may not be enough to reach definitive conclusions, but they are the basis for systematic reviews that synthesize the results of several studies. However, once clinical trials have been published, a poor description of the study design and lack of specific key words and descriptors make it difficult to retrieve them by electronic searches, thus requiring hand searching. OBJECTIVES: To compare the retrieving capacity between hand search and the multiple strategies of electronic searches for identifying clinical trials in Cuban medical journals, and to determine the terminology used for describing these studies. METHODS: We combined electronic searches in the Scientific Electronic Library Online of Cuba (SciELO Cuba) and Cuban database Cumed with hand search using the Cochrane guide to locate trials in three Cuban journals in the period 2000-2012. We identified the significant terms included in the title, summary, keywords and methods of each article according to Cochrane, CONSORT, and the health sciences thesaurus. RESULTS: We identified 50 trials by hand search; four of them were retrieved by electronic search through SciELO Cuba (8%) while none was found through Cumed. The less descriptive sections were the title and the keywords. More keywords than authorized descriptors were used; the only specific concepts used in over half of the retrieved trials were “controlled” (60%), and “study groups” (52%); “randomi-zed” was used in 50% of the retrieved documents. While more specific, the terms “clinical trial”, “phase”, and “clinical trial registration” were not used. CONCLUSIONS: Compared to hand searching, electronic searches are insufficient to identify clinical trials. Therefore, the combination of the two meth-ods is necessary to reach higher retrieval rates. The terminology used to describe clinical trials in the selected journals was deficient due to underutilization of the health sciences thesaurus.

INTRODUCCIÓN: Los ensayos clínicos se consideran la regla de oro para evaluar la eficacia y seguridad de las intervenciones. De manera independiente, pueden no ser suficientes para generalizar resultados, pero constituyen la base de revisiones sistemáticas que sintetizan sus resultados y suelen aportar evidencias de mayor calidad. Pero una vez publicados, la pobre descripción del método científico y el uso insuficiente de palabras clave, dificultan su recuperación por búsqueda electrónica y se requiere de la búsqueda manual. OBJETIVOS: Comparar la capacidad de recuperación entre la búsqueda manual y estrategias múltiples de búsqueda electrónica para localizar ensayos clínicos en revistas médicas cubanas, y determinar la terminología utilizada para describir el ensayo clínico. MÉTODOS: Se combinó la búsqueda electrónica en la biblioteca virtual Scientific Electronic Library Online de Cuba (SciELO Cuba), y la base de datos de bibliografía médica cubana Cumed con la búsqueda manual utilizando la guía de búsqueda de Cochrane, para localizar los ensayos en tres revistas cubanas en el período 2000 a 2012. Se identificaron los términos significativos incluidos en título, resumen, palabras clave y métodos de cada artículo según la guía Cochrane, CONSORT y el tesauro de ciencias de la salud. RESULTADOS: Se identificaron 50 ensayos en la búsqueda manual, de ellos cuatro coincidieron en la búsqueda electrónica; todos a través de SciELO Cuba (8%) y ninguno en Cumed. Las secciones menos descriptivas fueron el título y las palabras clave. Se utilizaron más palabras clave que descriptores autorizados; los únicos conceptos empleados en más de la mitad de los estudios fueron: “controlado” (60%) y “grupos de estudio” (52%); “aleatorizado” fue usado en el 50% de los artículos. Aunque son más específicos, no fueron muy usados los términos “ensayo clínico”, “fase” y “código del ensayo”. CONCLUSIONES: La búsqueda electrónica es insuficiente para la identificación de ensayos clínicos respecto de la búsqueda manual. Por lo tanto, se precisa la combinación de ambos métodos para lograr un mayor índice de recobrado. La terminología usada para describir los ensayos clínicos en las revistas seleccionadas fue deficiente, debido a la subutilización del tesauro de ciencias de la salud.

RESUMEN

OBJECTIVE: Search strategies are essential for the adequate retrieval of studies in a systematic review (SR). Our objective was to identify problems in the design and reporting of search strategies in a sample of new Cochrane SRs first published in The Cochrane Library in 2015. STUDY DESIGN AND SETTING: We took a random sample of 70 new Cochrane SRs of interventions published in 2015. We evaluated their design and reporting of search strategies using the recommendations from the Cochrane Handbook for Systematic Reviews of Interventions, the Methodological Expectations of Cochrane Intervention Reviews, and the Peer Review of Electronic Search Strategies evidence-based guideline. RESULTS: Most reviews complied with the reporting standards in the Cochrane Handbook and the Methodological Expectations of Cochrane Intervention Reviews; however, 8 SRs did not search trials registers, 3 SRs included language restrictions, and there was inconsistent reporting of contact with individuals and searches of the gray literature. We found problems in the design of the search strategies in 73% of reviews (95% CI, 60-84%) and 53% of these contained problems (95% CI, 38-69%) that could limit both the sensitivity and precision of the search strategies. CONCLUSION: We found limitations in the design and reporting of search strategies. We consider that a greater adherence to the guidelines could improve their quality.

RESUMEN

Objetiva desenvolver um percurso metodológico para recuperar informações científicas sobre as Doenças Tropicais Negligenciadas (DTN) em bases de dados internacionais (Scopus, Web of Science e PubMed). Os procedimentos metodológicos desta pesquisa foram: a) identificação das principais doenças tropicais segundo a Organização Mundial da Saúde; b) padronização dos nomes das doenças a partir dos Descritores em Ciências da Saúde da Biblioteca Virtual de Saúde (DeCS/BVS); c) construção de duas listas: uma com os termos controlados associados a operadores booleanos, e outra com os termos não controlados, também estruturada com operadores booleanos; d) busca de informações nas principais bases de dados anteriormente citadas de maneira controlada e não controlada; e) comparação dos resultados obtidos entre a busca controlada e não controlada; f) construção de fluxo metodológico para fins de replicação. Percebeu-se que o uso da busca controlada aumentou a revocação do processo de recuperação da informação, especificamente, a Base Scopus apresentou um aumento mais significativo na recuperação de resultados (11,28 %). A PubMed teve um incremento na revocação de 8,92 % e a Web of Science de 2,64 %. Ademais, propõe-se neste trabalho um fluxo para a recuperação da informação nas referidas bases, que sirva para os pesquisadores neste tema, pois entende-se que o alto grau de variabilidade das palavras e a dispersão na representação do tema nas bases constitui-se no importante impeditivo para a recuperação de informações(AU)

El objetivo de esta investigación fue desarrollar una metodología para recuperar informaciones científicas sobre las enfermedades tropicales desatendidas, en bases de datos internacionales (Scopus, Web of Science y PubMed). Los procedimientos metodológicos de esta investigación fueron: a) identificación de las principales enfermedades tropicales según la Organización Mundial de la Salud; b) estandarización de los nombres de las enfermedades a partir de los Descriptores en Ciencias de la Salud de la Biblioteca Virtual de Salud (DeCS/BVS); c) construcción de dos listas: una con los términos controlados asociados a operadores booleanos, y otra con los términos no controlados, también estructurada con operadores booleanos; d) búsqueda de informaciones en las principales bases de datos anteriormente citadas de manera controlada y no controlada; e) comparación de los resultados obtenidos entre la búsqueda controlada y no controlada; f) construcción de flujo metodológico para fines de replicación.

It aims to develop a methodological pathway for the retrieval of scientific information on neglected tropical diseases in international databases (Scopus, Web of Science and PubMed). The methodological procedures performed in this work were: a) identification of the main tropical diseases according to the World Health Organization; b) conversion of the names of the diseases in standardized terms from the Descriptors in Health Sciences of the Virtual Health Library (DeCS), c) the construction of two lists: one with the standard terms associated with Boolean operators, and the other with the nonstandard terms; d) search for information in the main databases previously mentioned in a standardized and non-standardized way; e) comparison of the results obtained between standardized and non-standardized search; f) methodological flow construction for replication purposes. As a main result it was observed that the use of the standardized search increased the recall of the information retrieval process, and Scopus was the basis that presented a more significant increase in the retrieval of results (11.28 %).

RESUMEN

Este artigo tem como base um estudo em que foram levantados e organizados termos do domínio da radiologia obstétrica e, então, foi identificado se os mesmos estão compreendidos em quatro distintos vocabulários controlados: OntoNeo, RadLex, LOINC e SNOMED. É apresentado o Sistema Integrado Catarinense de Telemedicina e Telessaúde (STT/SC) e o projeto de estruturação de laudos de exames de radiologia obstétrica, bem como o contexto teórico da ciência da informação sobre vocabulários controlados.Foram realizadas uma pesquisa de campo para o levantamento dos termos junto a um especialista da área e uma pesquisa documental para o levantamento estatístico dos termos em vocabulários controlados.Constituiu-se uma hierarquia dos termos levantados e verificou-se a cobertura de cada um dos vocabulários controlados em relação aos termos. O SNOMED é o vocabulário controlado com maior potencial de uso para a indexação de laudos no domínio da radiologia obstétrica.(AU)

This article bases on a study in which terms of the obstetric radiology domain were collected and arranged, and then we identified whether they are comprised in four distinct controlled vocabularies: OntoNeo, RadLex, LOINC and SNOMED. We present the STT/SC ­ Sistema Integrado Catarinense de Telemedicina e Telessaúde (Santa Catarina's integrated system of telemedicine and tele health) and theproject of structuring diagnostic reports of tests in obstetric radiology, as well as the theoretical contextof information science about controlled vocabulary. We carried out a survey of the terms jointly an expertand a documentary research to the statistical survey of the terms from controlled vocabularies. A hierarchy of the terms collected was established and the coverage of each of the controlled vocabularies in relation to the terms was verified. The SNOMED is the controlled vocabulary with greater potential of use for theindexation of diagnostic reports in the field of obstetric radiology.

Este artículo se basa en un estudio en el cual fueron levantados y arreglados términos del dominio de la radiología obstétrica, y entonces fue identificado si los mismos están comprendidos en cuatro distintos vocabularios controlados: el OntoNeo, el RadLex, el LOINC y el SNOMED. Presentamos el STT/SC ­ Sistema Integrado Catarinense de Telemedicina e Telessaúde (sistema integrado catarinense de telemedicina y telesalud) y el proyecto de estructuración de resultados de exámenes de radiología obstétrica, así como el contexto teórico de la ciencia de la información sobre vocabularios controlados. Una investigación de campo fue realizada para el levantamiento de los términos junto a un especialista y una investigación documental para el levantamiento estadístico de los términos en vocabularios controlados. Se ha constituido una jerarquía de los términos levantados y se ha verificado la cobertura de cada uno de los vocabularios controlados en relación a los términos. El SNOMED es el vocabulario controlado con mayor potencial deuso para la indexación de los resultados de exámenes en el dominio de la radiología obstétrica.

RESUMEN

Objetiva desenvolver um percurso metodológico para recuperar informações científicas sobre as Doenças Tropicais Negligenciadas (DTN) em bases de dados internacionais (Scopus, Web of Science e PubMed). Os procedimentos metodológicos desta pesquisa foram: a) identificação das principais doenças tropicais segundo a Organização Mundial da Saúde; b) padronização dos nomes das doenças a partir dos Descritores em Ciências da Saúde da Biblioteca Virtual de Saúde (DeCS/BVS); c) construção de duas listas: uma com os termos controlados associados a operadores booleanos, e outra com os termos não controlados, também estruturada com operadores booleanos; d) busca de informações nas principais bases de dados anteriormente citadas de maneira controlada e não controlada; e) comparação dos resultados obtidos entre a busca controlada e não controlada; f) construção de fluxo metodológico para fins de replicação. Percebeu-se que o uso da busca controlada aumentou a revocação do processo de recuperação da informação, especificamente, a Base Scopus apresentou um aumento mais significativo na recuperação de resultados (11,28 %). A PubMed teve um incremento na revocação de 8,92 % e a Web of Science de 2,64 %. Ademais, propõe-se neste trabalho um fluxo para a recuperação da informação nas referidas bases, que sirva para os pesquisadores neste tema, pois entende-se que o alto grau de variabilidade das palavras e a dispersão na representação do tema nas bases constitui-se no importante impeditivo para a recuperação de informações(AU)

El objetivo de esta investigación fue desarrollar una metodología para recuperar informaciones científicas sobre las enfermedades tropicales desatendidas, en bases de datos internacionales (Scopus, Web of Science y PubMed). Los procedimientos metodológicos de esta investigación fueron: a) identificación de las principales enfermedades tropicales según la Organización Mundial de la Salud; b) estandarización de los nombres de las enfermedades a partir de los Descriptores en Ciencias de la Salud de la Biblioteca Virtual de Salud (DeCS/BVS); c) construcción de dos listas: una con los términos controlados asociados a operadores booleanos, y otra con los términos no controlados, también estructurada con operadores booleanos; d) búsqueda de informaciones en las principales bases de datos anteriormente citadas de manera controlada y no controlada; e) comparación de los resultados obtenidos entre la búsqueda controlada y no controlada; f) construcción de flujo metodológico para fines de replicación. Se percibió que el uso de la búsqueda controlada aumentó la revocación del proceso de recuperación de la información. Específicamente la Base Scopus presentó un aumento más significativo en los resultados (11,28 %). PubMed tuvo un incremento en la revocación del 8,92 % y la Web of Science del 2,64 %.

It aims to develop a methodological pathway for the retrieval of scientific information on neglected tropical diseases in international databases (Scopus, Web of Science and PubMed). The methodological procedures performed in this work were: a) identification of the main tropical diseases according to the World Health Organization; b) conversion of the names of the diseases in standardized terms from the Descriptors in Health Sciences of the Virtual Health Library (DeCS), c) the construction of two lists: one with the standard terms associated with Boolean operators, and the other with the nonstandard terms; d) search for information in the main databases previously mentioned in a standardized and non-standardized way; e) comparison of the results obtained between standardized and non-standardized search; f) methodological flow construction for replication purposes. As a main result it was observed that the use of the standardized search increased the recall of the information retrieval process, and Scopus was the basis that presented a more significant increase in the retrieval of results (11.28 %). PubMed had an increase in recall of 8.92 % and Web of Science of 2.64 %. In addition, it is proposed in this work a flow for the retrieval of the information in the mentioned bases, that can be useful to all the researchers who wish to obtain scientific information on this subject, since it is understood that the high degree of variability of the words and the dispersion in the representation of the theme in the bases constitutes the important impediment for the information retrieval(AU)
