Abstract
The objective is to automatically identify trends in Fetal Medicine over the past 10 years through a bibliometric analysis of articles published in Prenatal Diagnosis, using text mining techniques. We processed 2,423 full-text articles published in Prenatal Diagnosis between 2006 and 2015. We extracted salient terms, calculated their frequencies over time, and established evolution profiles for terms, from which we derived falling, stable, and rising trends. We identified 618 terms with a falling trend, 2,142 stable terms, and 839 terms with a rising trend. Terms with increasing frequencies include those related to statistics and medical study design. The most recent of these terms reflect the new opportunities of next-generation sequencing. Many terms related to cytogenetics exhibit a falling trend. A bibliometric analysis based on text mining effectively supports identification of trends over time. This scalable approach is complementary to analyses based on metadata or expert opinion.

Risk factors, representations and practices associated with emerging urban human visceral leishmaniasis in Posadas, Argentina. BIOMEDICA 2016; 36:51-63. [PMID: 27622625 DOI: 10.7705/biomedica.v36i2.2953] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Revised: 09/09/2015] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Visceral leishmaniasis is an often overlooked disease with high lethality rates about which there is need of additional local studies to inform the design of effective control strategies. The urbanization of its transmission has already been verified in America, with domestic dogs being the primary reservoirs and vectors of the disease. Socio-economic conditions, demographics and practices of domestic groups typically present in urban settings may play a specific role in the transmission of the infection, which is still poorly understood. OBJECTIVE To analyze the sociodemographic characteristics, risk factors and overall practices concerning prevention and coping strategies of visceral leishmaniasis, in both human beings and canines. MATERIALS AND METHODS This study utilized a cross-sectional case-control design. Cases were defined as a domestic group where the Public Health Ministry had at least one record of a member with human visceral leishmaniasis. Control cases were defined as a domestic group without a clinical record of the disease. The populations were characterized demographically and socially using primary information sources. Measures of household quality and a ranking of knowledge and attitudes towards visceral leishmaniasis were constructed, and practices associated with the presence, and the risk for canine visceral leishmaniasis were described. RESULTS Low household quality (p≤0.001), a member of the domestic group out of the household after 6:00 pm (OR=4.4; 95% CI: 1.69-12.18), the uncontrolled racial breeding of dogs (OR=15.7; 95% CI: 3.91-63.2), and the presence of infected dogs infected in the household (OR=120.3; 95% CI: 18.51-728.3) were variables positively associated with the risk of infection. CONCLUSION We observed certain social risk factors, primarily low household quality and overcrowding, associated with structural poverty that could increase human-vector contact probability. The most important risk factor for human visceral leishmaniasis was the possession of infected dogs in the household.

Hong Y, Yao Q, Yang Y, Feng JJ, Wu SD, Ji WX, Yao L, Liu ZY. Knowledge structure and theme trends analysis on general practitioner research: A Co-word perspective. BMC FAMILY PRACTICE 2016; 17:10. [PMID: 26831329 PMCID: PMC4734860 DOI: 10.1186/s12875-016-0403-5] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2014] [Accepted: 01/15/2016] [Indexed: 01/13/2023]
Abstract
BACKGROUND General practitioners (GPs) are the most important providers of primary health care, as proven by related research published several decades ago. However, the knowledge structure and theme trends of such research remain unclear. Accordingly, this study aimed to provide an overview of the development of research on GPs over the period of 1999 to 2014. METHODS Studies on GPs conducted from 1999 to 2014 were retrieved from PubMed. In this work, co-word, social network analysis, and theme trends analyses were conducted to reveal the knowledge structures and thematic evolution of research on GPs. RESULTS The number of conducted studies on GPs increased. However, growth speed slowed down during the past 16 years. A total of 27 high-frequency keywords were identified in 1999 to 2003, and more new and specific high-frequency keywords emerged in the subsequent periods. The dynamic of this field was first divergent and then considered convergent. Specifically, network centralization is 19.77%, 19.09%, and 13.04% in 1999 to 2003, 2004 to 2008 and 2009 to 2014, respectively. The major topics of research on GPs completed from 1999 to 2014 were "physician/family,""attitude of health personnel," and "primary health care," and "general practitioner" communities, and so on. CONCLUSION The research themes on GPs are relatively stable at the beginning of the 21(st) century. However, the thematic evolution and research topics of research on GPs are changing dynamically in recent years. Themes related to the roles and competencies of GPs, and the relations between general practitioner and patients/others have become research foci on GPs. In addition, more substantial research especially on comprehensive approaches and holistic modeling, which have been defined in the European Definition of General Practice/Family Medicine, are expected to be accomplished.
