Luto gestacional e neonatal: emergência de uma nova problemática / Gestational and neonatal mourning: emergency of a new social problem

Esta dissertação investiga a construção dos fenômenos da morte e do luto gestacional e neonatal como problemática social e experiência de saúde na contemporaneidade. A medicina e os avanços tecnológicos têm promovido transformações relativas aos valores acerca da reprodução e do nascituro/recém-nascido. A redução das taxas de mortalidade alcançadas pela medicina a partir da metade do séc. XX oblitera o tema dos possíveis desenlaces fatais das gestações. Qualificados como "bebês", conceptos encarnam projetos de família e, por conseguinte, podem adquirir para o par parental o estatuto de pessoa, ainda que sua vida não tenha vingado. Diante do óbito prematuro (seja na gestação ou no pós-parto), observa-se o desinvestimento médico e dos serviços de saúde: as mulheres acometidas padecem de invisibilidade e ausência de cuidado. Este trabalho consiste, de um lado, na abordagem etnográfica documental dos Descritores em Ciências da Saúde (DeCS/MeSH) com o objetivo de delinear valores e normas de conduta biomédicos relacionados à assistência reprodutiva e à do recém-nascido. O conjunto de classificações biomédicas é permeado por moralidades distintas que concedem ora a condição de resto fetal, ora o estatuto de pessoa, paciente e cidadão. De outro lado, dada a escassez de literatura brasileira, foram analisadas produções feministas/acadêmicas norte-americanas e francesas acerca da crescente visibilização do fenômeno do luto gestacional e neonatal (LGNN). Em resposta ao vácuo social do par parental cujo filho não sobreviveu, profissionais e acadêmicas engajam-se na ressignificação dos projetos de maternidade (e paternidade) interrompidos. São discursos e práticas calcados em críticas à episteme e hierarquia médicas. O entrelaçamento entre afetação e saber especializado oferece visibilidade e inserção coletiva às trajetórias femininas atravessadas pela morte prematura de filhos; o ideário do luto GNN concede novos sentidos à procriação, ao corpo feminino e à pessoa do nascituro/recém-nascido.

This dissertation investigates the construction of the phenomena of gestational and neonatal death and mourning as a contemporary social problem and health experience. Technological advances have promoted changes in the values of reproduction and personhood of the unborn/newborn. The decrease of the mortality rates, achieved by the applied medical science in the middle of the twentieth century, obliterates possible fatalities in the outcomes of pregnancies. Qualified as "babies", unborn children embody family projects and can be given the sense of personhood, regardless of its survival. However, when facing premature death (gestational or after birth), doctors and caregivers reduce the offers of services: affected women suffer from invisibility and absence of care. This research consists, on one hand, in the ethnography of Medical Subject Headings (DeCS/MeSH) to delineate biomedical values and norms of conduct related to reproductive and neonatal care. The set of biomedical classifications is permeated by ambiguous moralities that sometimes grant the condition of fetal waste, or the status of person, patient, and citizen. On the other hand, given the lack of Brazilian literature, North American and French authors ground the analysis of the growing visibility of the phenomenon of gestational and neonatal mourning. In response to the social gap experienced by the couple whose child did not survive, caregivers and academics engage themselves in the production of frames for the interrupted projects of motherhood (and fatherhood). The discourses and practices are based on criticisms of the medical knowledge and hierarchy. The intertwining between affectation and expertise offers visibility and integration to the women who suffered the premature death of their children; the ideology of gestational and neonatal (GNN) mourning assigns new meanings to the process of procreation, the female body, and the personhood of the unborn/newborn.

New Health Sciences Descriptors to classify and retrieve information on equity / Nuevos Descriptores en Ciencias de la Salud para clasificar y recuperar información sobre equidad

ABSTRACT The Health Sciences Descriptors (DeCS) vocabulary establishes a unique and common language that allows the organization and facilitates the search and retrieval of technical and scientific literature on health available in the information sources of the Virtual Health Library. The DeCS, created by the Latin American and Caribbean Center on Health Sciences Information (BIREME), a specialized center of the Pan American Health Organization/World Health Organization (PAHO/WHO), is the translation and extension of the Medical Subject Headings (MeSH) vocabulary, maintained by the United States National Library of Medicine. BIREME, in coordination with experts from Latin America and the Caribbean, has included in the DeCS the topics of equity, gender, ethnicity and human rights—cross-cutting themes in the programmatic framework of PAHO/WHO technical cooperation—to ensure better retrieval and use of scientific information and evidence related to these topics. The objective of this article is to describe the methodology used during the terminology review of the DeCS and to report the results obtained and the impacts of the terminology expansion in the field of equity, which included the inclusion of 35 new descriptors.

Glosario para una pandemia: el ABC de los conceptos sobre el coronavirus / Pandemic's glossary: The ABC of coronavirus concepts

Actualmente, el mundo se enfrenta a la pandemia generada por el SARS-CoV-2, infección para la cual no hay medidas farmacológicas de prevención ni tratamiento. Hasta el momento, ha dejado más de 4'880.000 casos confirmados y 322.000 muertes. Se han propuesto diferentes estrategias para el control de la enfermedad que implican la participación de diferentes sectores de la sociedad con acciones guiadas por lineamientos jurídicos y basados en medidas de salud pública, entre ellas, la contención, la mitigación, el aislamiento físico y la cuarentena. Dado que se trata de una situación de dimensión poblacional, la información tiene un papel fundamental; sin embargo, la proliferación de términos nuevos, muchas veces usados erróneamente, causa confusión y desinformación y, en consecuencia, limitan la participación ciudanía. En ese contexto, en el presente documento se hizo una revisión de los términos utilizados en epidemias y pandemias de enfermedades infecciosas, con énfasis en la COVID-19, para facilitar al público general la comprensión de los términos relevantes sobre el comportamiento de los agentes patógenos y de su ciclo epidémico y pandémico, así como los criterios para la adopción de las decisiones pertinentes en salud pública. Se aspira a que el glosario resultante ayude al uso correcto de los términos y a homogenizar la información.

Currently, the world is facing the pandemic generated by SARS-CoV-2. There are no no pharmacological measures for the prevention or treatment of this infection and, so far, it has caused more than 4'880.000 confirmed cases and 322.000 deaths. The different strategies for the control of the disease that have been proposed involve the participation of different actors. Such participation, guided by legal guidelines based on public health measures, include containment, mitigation, physical isolation, and quarantine. As this is a population-based problem, information plays a primary role; however, the many new terms hat have arisen and their misuse confuse and, therefore, misinform thus limiting citizen participation. For this reason, we conducted a review of the terms used in epidemics and pandemics of infectious diseases, particularly COVID-19. We considered and differentiated the relevant terms to facilitate the understanding of pathogen's behavior and epidemic and pandemic cycles, as well as the criteria for public health decision-making for the general public. This glossary should facilitate the use of the terms and standardize the information.

Septate uterus with double cervix and longitudinal vaginal septum – A report of two cases of rare uterine anomaly

Background: Embryological maldevelopment of the Mullerian or paramesonephric duct results in congenital uterine anomalies. A rare developmental anomaly is a septate uterus with cervical duplication and a longitudinal vaginal septum. This anomaly cannot be explained by the classical unidirectional Mullerian developmental theory and does not fit into American Society for Reproductive Medicine (ASRM) classification of uterine anomalies. The bidirectional Mullerian developmental theory holds good for this type of anomalies and the new ESHRE/ESGE classification for female urogenital tract anomaly (CONUTA) is more suitable for effective categorization, diagnosis, and treatment.Case Report: Two cases of the complete uterine septum with double cervix and longitudinal vaginal septum who presented with dysmenorrhea, dyspareunia, and infertility were diagnosed and managed by hysteroscopy and laparoscopy. The vaginal and the uterine septum were resected. Both the patients had an uneventful post-operative recovery period and were followed up for a period of 1 year. The symptoms such as dysmenorrhea and dyspareunia improved significantly without any effect on the fertility outcome.Conclusion:Very few of such cases are reported in the literature. This rare anomaly is explained by the bidirectional Mullerian developmental theory and the application of the new ESHRE/ESGE classification of the urogenital tract (CONUTA) is more suitable for such anomalies for effective categorization, diagnosis, and treatment.

Abstract Introduction: the PICO mnemonic is an evidence-based medicine tool that helps formulate the research questions needed to conduct the right search for scientific information. To properly classify this information, controlled languages or thesauruses are used for information retrieval. The aim was to identify whether the PICO search strategy in evidence-based medicine using the MeSH, Emtree and DeCS thesauruses answers a research question in the field of dentistry. Methods: to carry out the PICO strategy, a research question was formulated, identifying the natural language terms for each component of the PICO acronym, which were normalized into the three thesauruses to create the search equations. Results: 43 results were found on Medline through PubMed, 5 on Embase, and 0 on LILACS. There were 4 original articles that answer the research question, proving to be an effective strategy for finding clinical evidence. Conclusion: this study shows that the strategy helps obtain results to answer the question posed. It should be noted that, in order to successfully search and retrieve information, researchers should use the PICO strategy and get familiar with the thesauruses that help structure search equations in the various bibliographic databases.

Strategies to optimize MEDLINE and EMBASE search strategies for anesthesiology systematic reviews. An experimental study

ABSTRACT BACKGROUND: A high-quality electronic search is essential for ensuring accuracy and comprehensiveness among the records retrieved when conducting systematic reviews. Therefore, we aimed to identify the most efficient method for searching in both MEDLINE (through PubMed) and EMBASE, covering search terms with variant spellings, direct and indirect orders, and associations with MeSH and EMTREE terms (or lack thereof). DESIGN AND SETTING: Experimental study. UNESP, Brazil. METHODS: We selected and analyzed 37 search strategies that had specifically been developed for the field of anesthesiology. These search strategies were adapted in order to cover all potentially relevant search terms, with regard to variant spellings and direct and indirect orders, in the most efficient manner. RESULTS: When the strategies included variant spellings and direct and indirect orders, these adapted versions of the search strategies selected retrieved the same number of search results in MEDLINE (mean of 61.3%) and a higher number in EMBASE (mean of 63.9%) in the sample analyzed. The numbers of results retrieved through the searches analyzed here were not identical with and without associated use of MeSH and EMTREE terms. However, association of these terms from both controlled vocabularies retrieved a larger number of records than did the use of either one of them. CONCLUSIONS: In view of these results, we recommend that the search terms used should include both preferred and non-preferred terms (i.e. variant spellings and direct/indirect order of the same term) and associated MeSH and EMTREE terms, in order to develop highly-sensitive search strategies for systematic reviews.

Citation Analysis for Biomedical and Health Sciences Journals Published in Korea / 대한의료정보학회지

OBJECTIVES: A citation analysis of biomedical and health sciences journals was conducted based on their enlistment in journal databases to identify the factors contributing to the citation metrics. METHODS: Among the 1,219 academic journals managed by the National Center for Medical Information and Knowledge at the Korea Centers for Disease Control and Prevention, 556 journals were included for analysis as of July 2016. The characteristics of the journals include history years, publication media, language, open-access policy as well as the status enlisted in international and domestic databases, such as Science Citation Index (SCI), Scopus, Medline, PubMed Central, Embase, and Korea Citation Index (KCI). Six bibliometric measures were collected from SCI, Scopus, and KCI as of 2015, the most recent disclosure year. Analyses of group differences and influential factors were conducted using t-tests, Mann-Whitney tests, and multiple regression. RESULTS: Journal characteristics, such as history years, publication media, and open-access policy, were not significant factors influencing global or domestical citation of the journals. However, global citations were higher for SCI and Medline enlisted journals than for their counterparts. Among KCI journals, the KCI impact factors of journals published in English only were lower. CONCLUSIONS: Efforts by journals to be enlisted in international databases, especially in SCI and Medline, are critical to enhance their global circulation. However, articles published in English only hinder the use of domestic researchers. Different strategies are required for enhancing international and domestic readerships.

Evolution of the thematic structure of oncology based on the co-word analysis / 国际肿瘤学杂志

Objective To explore the changes of the internal structure and research topics of oncology from 2005 to 2014,and offer reference for the development of the related studies and research policies. Methods The articles published in 203 journals in the area of oncologyfrom 2005 to 2014 included by JCR were chosen.Firstly,we cleaned the author keywords using the TDA software.After that,we standardized and categorized the keywords according to the Medical Subject Headings (MeSH)manually.In the end,we builted the co-occurrence matrixes of high-frequency words in three stages:2005—2007,2008—2010 and 2011 —2014, and drew the evolution maps and strategic diagrams of each stage to analyze the changes of the internal structure and research topics of oncology.Results While the word frequence increasing rapidly,the main keywords reduced gradually from 2005 to 2014.The traditional treatments such as chemotherapy and radiotherapy,the diagnostic and the epidemiological investigation were the core subject of oncology.With the screening of neoplasms,the research on the cell physiological phenomena and the genetic phenomena gained vigorous expan-sion.Breast neoplasms,the topic whose deep exploration also led the development of other topics,has always been the hard nut as well as the hot topic of the oncology.During this period,researches on the screening of neo-plasms and the genetic phenomena were developed rapidly.Conclusion The content of oncology will be more thoroughly with some merge,division,development,declining and perishing of the internal themes occurred as well.The boundaries among the sub-structure are becoming more and more blurred and the screening of neo-plasms and the genetic phenomena has gradually become the dominant trend in general practices.

PubMed alternatives to search MEDLINE: An environmental scan.

The prime objective of this article is to introduce the newer methods to access, search and process MEDLINE citations. It also aims to provide a brief overview of each service’s salient features. A targeted search was conducted in MEDLINE through the OVID gateway. This was followed with a search in Google Scholar as well as Google and Bing. Ninety‑two web‑based services that can be used to search MEDLINE were identified. The list was shortened to 24 by applying a set of relevancy criteria to select those services more relevant to general medical and dental users. Salient features of the selected services are outlined and a use case based classification of the system has been proposed to help dental practitioners and researchers select the appropriate service for a given purpose.

MÉTODOS: Estudio descriptivo transversal a partir de los artículos publicados en la RPSP entre 1997 y 2012. Se analizaron indicadores bibliométricos de productividad (documentos publicados, idiomas, autoría, e índices de productividad y colaboración); repercusión (factor de impacto según la Red SciELO, Journal Citation Report y SCImago); palabras clave; y referencias bibliográficas, su estructura (tipo de documento y núcleo principal de Bradford) y grado de obsolescencia (semiperíodo de Burton y Kebler, e índice de Price), entre otros. RESULTADOS: Se publicaron 2 815 artículos con una mediana de 3 autores y 2 instituciones por artículo. La proporción de artículos de investigación original aumentó en 2008-2012 con respecto a 2003-2007 y 1997-2002 (P < 0,001). El idioma predominante fue el español, desplazado por el inglés en los últimos 5 años. De las palabras clave, 88,76% se correspondían con los Descriptores en Ciencias de la Salud (DeCS) y mostraron una orientación salubrista y comunitaria dirigida a las Américas. El semiperíodo de Burton y Kebler de las referencias bibliográficas fue de 8 años, aunque bajó a 5 años en 2012; el índice de Price fue de 20,47%, y el núcleo de Bradford lo conformaron 20 revistas de la corriente principal; el porcentaje de autocitas fue bajo (2,07%). CONCLUSIONES: La RPSP es una publicación internacional con indicadores bibliométricos similares a los de las revistas latinoamericanas más representativas de las ciencias de la salud, con mejoras en los últimos años estudiados que la llevan a cumplir totalmente con los criterios editoriales internacionales.

OBJECTIVE: To characterize the scientific output of the Revista Panamericana de Salud Pública/Pan American Journal of Public Health (RPSP) as a scientific publication of reference in the public health sector in the Americas. METHODS: A descriptive cross-sectional study was conducted based on the articles published in the RPSP from 1997-2012. Bibliometric indicators of productivity (documents published, languages, authorship, and indices of productivity and collaboration); impact (impact factor according to the SciELO Network, Journal Citation Report and SCImago); key words; and bibliographic references, their structure (document type and main nucleus of Bradford) and degree of obsolescence (Burton and Kebler half-life, and Price index), were analyzed. RESULTS: A total of 2 815 articles with a median of 3 authors and 2 institutions per article were published. The percentage of original research articles increased in 2008-2012 compared to 2003-2007 and 1997-2002 (P < 0.001). The predominant language was Spanish, displaced by English in the last 5 years. A total of 88.76% of the key words referred to the Health Sciences Descriptors (DeCS) and had a public health and community orientation related to the Americas. The Burton and Kebler half-life of bibliographic references was 8 years, although it decreased to 5 years in 2012. The Price index was 20.47% and the nucleus of Bradford was made up of 20 mainstream journals. The percentage of self-citation was low (2.07%). CONCLUSIONS: The RPSP is an international publication with bibliometric indicators similar to those of the most representative Latin American health science journals, with improvements in the recent years studied that lead it to fully meet international publishing criteria.

Use of Medical Subject Headings (MeSH) in the Journal of the Korean Orthopaedic Association / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to analyze the equality between author key words used in the Journal of the Korean Orthopaedic Association and controlled vocabulary or medical subject headings (MeSH). MATERIALS AND METHODS: A total of 1,058 English key words in 320 papers (average 3.3 words in a paper) from 2009 to 2012 were eligible for this study. We classified them according to matched, partially matched, and non-matched terms. The partially matched terms were further dissected into entry terms, qualifiers, anteriorly or posteriorly matched, abbreviations, and pleurals. After descriptive analysis, we assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. RESULTS: The rate of matched terms was 23.5% for an average of four years, and 34.8% for 2013, which is on the rise by year. The rate of partially matched terms was 34.8%, and that of non-matched terms was 41.7% for an average of four years. The most frequently used key words were Knee and Total knee arthroplasty (17 times), followed by Osteoarthritis (9), Femur, Hip, and Total hip arthroplasty (8). CONCLUSION: Use of proper keywords aligned with the international standards such as MeSH is important to be properly cited. The authors should pay attention and be educated on correct use of MeSH as key words.

Social Network Analysis of Elders' Health Literacy and their Use of Online Health Information / 대한의료정보학회지

OBJECTIVES: Utilizing social network analysis, this study aimed to analyze the main keywords in the literature regarding the health literacy of and the use of online health information by aged persons over 65. METHODS: Medical Subject Heading keywords were extracted from articles on the PubMed database of the National Library of Medicine. For health literacy, 110 articles out of 361 were initially extracted. Seventy-one keywords out of 1,021 were finally selected after removing repeated keywords and applying pruning. Regarding the use of online health information, 19 articles out of 26 were selected. One hundred forty-four keywords were initially extracted. After removing the repeated keywords, 74 keywords were finally selected. RESULTS: Health literacy was found to be strongly connected with 'Health knowledge, attitudes, practices' and 'Patient education as topic.' 'Computer literacy' had strong connections with 'Internet' and 'Attitude towards computers.' 'Computer literacy' was connected to 'Health literacy,' and was studied according to the parameters 'Attitude towards health' and 'Patient education as topic.' The use of online health information was strongly connected with 'Health knowledge, attitudes, practices,' 'Consumer health information,' 'Patient education as topic,' etc. In the network, 'Computer literacy' was connected with 'Health education,' 'Patient satisfaction,' 'Self-efficacy,' 'Attitude to computer,' etc. CONCLUSIONS: Research on older citizens' health literacy and their use of online health information was conducted together with study of computer literacy, patient education, attitude towards health, health education, patient satisfaction, etc. In particular, self-efficacy was noted as an important keyword. Further research should be conducted to identify the effective outcomes of self-efficacy in the area of interest.

Developing a Biomedical Expert Finding System Using Medical Subject Headings / 대한의료정보학회지

OBJECTIVES: Efficient identification of subject experts or expert communities is vital for the growth of any organization. Most of the available expert finding systems are based on self-nomination, which can be biased, and are unable to rank experts. Thus, the objective of this work was to develop a robust and unbiased expert finding system which can quantitatively measure expertise. METHODS: Medical Subject Headings (MeSH) is a controlled vocabulary developed by the National Library of Medicine (NLM) for indexing research publications, articles and books. Using the MeSH terms associated with peer-reviewed articles published from India and indexed in PubMed, we developed a Web-based program which can be used to identify subject experts and subjects associated with an expert. RESULTS: We have extensively tested our system to identify experts from India in various subjects. The system provides a ranked list of experts where known experts rank at the top of the list. The system is general; since it uses information available with the PubMed, it can be implemented for any country. CONCLUSIONS: The expert finding system is able to successfully identify subject experts in India. Our system is unique because it allows the quantification of subject expertise, thus enabling the ranking of experts. Our system is based on peer-reviewed information. Use of MeSH terms as subjects has standardized the subject terminology. The system matches requirements of an ideal expert finding system.

An analysis of the articles published in the Journal of Korean Academy of Oral Health, from 1995 to 2012 / 대한구강보건학회지

OBJECTIVES: This study proposes to trace the development of the Journal of Korean Academy of Oral Health by analyzing its articles. METHODS: All of the articles published in the Journal of Korean Academy of Oral Health from 1995 to 2012 were assessed and analyzed with regard to the following: research design, MeSH database keywords, and statistical method. RESULTS: The total number of published articles was 830. This journal has conducted based on the relatively weak research designs and statistical analysis, and keyword does not matched with MeSH terms. The most frequently used research design was cross-sectional (53.1%). The statistical methods most often used were the F-test, t-test and contingency table. Only 34.3% of keywords matched MeSH terms. CONCLUSIONS: It was confirmed that the activities of the field of Journal of Korean Academy of Oral Health have become more prevalent over the past 18 years. In order to develop the quality of the journal, more systematic, refined study designs and methods are needed. It is also urgently essential that authors understand MeSH terms, and the Journal of Korean Academy of Oral Health should request that authors use accurate MeSH terms as their keywords when they submit articles.
