    PubMed related article links identify closely related articles and enhance our ability to navigate the biomedical literature. They are derived by calculating the word similarity between two articles, relating articles with overlapping word content. In this paper, we propose to enrich PubMed with a new type of related article link based on citations within a single sentence (i.e. sentence level co-citations or SLCs). Using different similarity metrics, we demonstrated that articles linked by SLCs are highly related. We also showed that only half of SLCs are found among PubMed related article links. Additionally, we discuss how the citing sentence of an SLC explains the connection between two articles. PMID:20351935

    Articles reporting survival outcomes (time-to-event outcomes) in patients over time are challenging to identify in the literature. Research shows the words authors use to describe their dental survival analyses vary, and that allocation of medical subject headings by MEDLINE indexers is inconsistent. Together, this undermines accurate article identification. The present study aims to develop and validate a search strategy to identify dental survival analyses indexed in MEDLINE (Ovid). A gold standard cohort of articles was identified to derive the search terms, and an independent gold standard cohort of articles was identified to test and validate the proposed search strategies. The first cohort included all 6,955 articles published in the 50 dental journals with the highest impact factors in 2008, of which 95 articles were dental survival articles. The second cohort included all 6,514 articles published in the 50 dental journals with the highest impact factors for 2012, of which 148 were dental survival articles. Each cohort was identified by a systematic hand search. Performance parameters of sensitivity, precision, and number needed to read (NNR) for the search strategies were calculated. Sensitive, precise, and optimized search strategies were developed and validated. The performances of the search strategy maximizing sensitivity were 92% sensitivity, 14% precision, and 7.11 NNR; the performances of the strategy maximizing precision were 93% precision, 10% sensitivity, and 1.07 NNR; and the performances of the strategy optimizing the balance between sensitivity and precision were 83% sensitivity, 24% precision, and 4.13 NNR. The methods used to identify search terms were objective, not subjective. The search strategies were validated in an independent group of articles that included different journals and different publication years. Across the three search strategies, dental survival articles can be identified with sensitivity up to 92%, precision up to 93

    The growing presence of research shared on social media, coupled with the increase in freely available research, invites us to ask whether scientific articles shared on platforms like Twitter diffuse beyond the academic community. We explore a new method for answering this question by identifying 11 articles from two open access biology journals that were shared on Twitter at least 50 times and by analyzing the follower network of users who tweeted each article. We find that diffusion patterns of scientific articles can take very different forms, even when the number of times they are tweeted is similar. Our small case study suggests that most articles are shared within single-connected communities with limited diffusion to the public. The proposed approach and indicators can serve those interested in the public understanding of science, science communication, or research evaluation to identify when research diffuses beyond insular communities.

    Consulting the Internet for health-related information is a common and widespread phenomenon, and Wikipedia is arguably one of the most important resources for health-related information. Therefore, it is relevant to identify factors that have an impact on the quality of health-related Wikipedia articles. In our study we have hypothesized a positive effect of contributor experience on the quality of health-related Wikipedia articles. We mined the edit history of all (as of February 2017) 18,805 articles that were listed in the categories on the portal health & fitness in the English language version of Wikipedia. We identified tags within the articles' edit histories, which indicated potential issues with regard to the respective article's quality or neutrality. Of all of the sampled articles, 99 (99/18,805, 0.53%) articles had at some point received at least one such tag. In our analysis we only considered those articles with a minimum of 10 edits (10,265 articles in total; 96 tagged articles, 0.94%). Additionally, to test our hypothesis, we constructed contributor profiles, where a profile consisted of all the articles edited by a contributor and the corresponding number of edits contributed. We did not differentiate between rollbacks and edits with novel content. Nonparametric Mann-Whitney U-tests indicated a higher number of previously edited articles for editors of the nontagged articles (mean rank tagged 2348.23, mean rank nontagged 5159.29; U=9.25, P<.001). However, we did not find a significant difference for the contributors' total number of edits (mean rank tagged 4872.85, mean rank nontagged 5135.48; U=0.87, P=.39). Using logistic regression analysis with the respective article's number of edits and number of editors as covariates, only the number of edited articles yielded a significant effect on the article's status as tagged versus nontagged (dummy-coded; Nagelkerke R 2 for the full model=.17; B [SE B]=-0.001 [0.00]; Wald c 2 [1]=19.70; P<.001

    The development of high-throughput genomic technologies has impacted many areas of genetic research. While many applications of these technologies focus on the discovery of genes involved in disease from population samples, applications of genomic technologies to an individual’s genome or personal genomics have recently gained much interest. One such application is the identification of relatives from genetic data. In this application, genetic information from a set of individuals is collected in a database, and each pair of individuals is compared in order to identify genetic relatives. An inherent issue that arises in the identification of relatives is privacy. In this article, we propose a method for identifying genetic relatives without compromising privacy by taking advantage of novel cryptographic techniques customized for secure and private comparison of genetic information. We demonstrate the utility of these techniques by allowing a pair of individuals to discover whether or not they are related without compromising their genetic information or revealing it to a third party. The idea is that individuals only share enough special-purpose cryptographically protected information with each other to identify whether or not they are relatives, but not enough to expose any information about their genomes. We show in HapMap and 1000 Genomes data that our method can recover first- and second-order genetic relationships and, through simulations, show that our method can identify relationships as distant as third cousins while preserving privacy.

    We used bibliometric analysis methodology in the expanded Science Citation Index to identify highly-cited electrocardiogram (ECG)-related articles with total citations (TC2012) exceeding 100 from the publication year to 2012. Web of Science search tools were used to identify the highly-cited articles. The aspects analyzed for highly cited publications included effect of time on citation analysis, journals and Web of Science categories, number of authors per publication, originating institutions and countries, total citation and total citation per year life cycles of articles (C2012) and research hotspots. Results showed that a total of 467 electrocardiogram-related publications were regarded as the highly-cited publications. TC2012 ranged from 101 to 2879, with 215 as the average number of citations. No highly-cited publications have emerged yet during the first two years of the present 2010 Decade. All 11 countries and institutions originating highly-cited ECG-related publications were developed countries, USA in 9 of them. Four subject categories were identified as hotspots by total citations TC2012 and C2012: atrial fibrillation, long QT syndrome, angina and myocardial infarction, and risk factor analysis and health evaluation.

    Evaluating the impact of a scholarly article is of great significance and has attracted great attentions. Although citation-based evaluation approaches have been widely used, these approaches face limitations e.g. in identifying anomalous citations patterns. This negligence would inevitably cause unfairness and inaccuracy to the article impact evaluation. In this study, in order to discover the anomalous citations and ensure the fairness and accuracy of research outcome evaluation, we investigate the citation relationships between articles using the following factors: collaboration times, the time span of collaboration, citing times and the time span of citing to weaken the relationship of Conflict of Interest (COI) in the citation network. Meanwhile, we study a special kind of COI, namely suspected COI relationship. Based on the COI relationship, we further bring forward the COIRank algorithm, an innovative scheme for accurately assessing the impact of an article. Our method distinguishes the citation strength, and utilizes PageRank and HITS algorithms to rank scholarly articles comprehensively. The experiments are conducted on the American Physical Society (APS) dataset. We find that about 80.88% articles contain contributed citations by co-authors in 26,366 articles and 75.55% articles among these articles are cited by the authors belonging to the same affiliation, indicating COI and suspected COI should not be ignored for evaluating impact of scientific papers objectively. Moreover, our experimental results demonstrate COIRank algorithm significantly outperforms the state-of-art solutions. The validity of our approach is verified by using the probability of Recommendation Intensity.

  14. Using distant supervised learning to identify protein subcellular localizations from full-text scientific articles.

    Databases of curated biomedical knowledge, such as the protein-locations reflected in the UniProtKB database, provide an accurate and useful resource to researchers and decision makers. Our goal is to augment the manual efforts currently used to curate knowledge bases with automated approaches that leverage the increased availability of full-text scientific articles. This paper describes experiments that use distant supervised learning to identify protein subcellular localizations, which are important to understand protein function and to identify candidate drug targets. Experiments consider Swiss-Prot, the manually annotated subset of the UniProtKB protein knowledge base, and 43,000 full-text articles from the Journal of Biological Chemistry that contain just under 11.5 million sentences. The system achieves 0.81 precision and 0.49 recall at sentence level and an accuracy of 57% on held-out instances in a test set. Moreover, the approach identifies 8210 instances that are not in the UniProtKB knowledge base. Manual inspection of the 50 most likely relations showed that 41 (82%) were valid. These results have immediate benefit to researchers interested in protein function, and suggest that distant supervision should be explored to complement other manual data curation efforts.

    Industrial support of biomedical research may bias scientific conclusions, as demonstrated by recent analyses of pharmaceutical studies. However, this issue has not been systematically examined in the area of nutrition research. The purpose of this study is to characterize financial sponsorship of scientific articles addressing the health effects of three commonly consumed beverages, and to determine how sponsorship affects published conclusions. Medline searches of worldwide literature were used to identify three article types (interventional studies, observational studies, and scientific reviews) about soft drinks, juice, and milk published between 1 January, 1999 and 31 December, 2003. Financial sponsorship and article conclusions were classified by independent groups of coinvestigators. The relationship between sponsorship and conclusions was explored by exact tests and regression analyses, controlling for covariates. 206 articles were included in the study, of which 111 declared financial sponsorship. Of these, 22% had all industry funding, 47% had no industry funding, and 32% had mixed funding. Funding source was significantly related to conclusions when considering all article types (p = 0.037). For interventional studies, the proportion with unfavorable conclusions was 0% for all industry funding versus 37% for no industry funding (p = 0.009). The odds ratio of a favorable versus unfavorable conclusion was 7.61 (95% confidence interval 1.27 to 45.73), comparing articles with all industry funding to no industry funding. Industry funding of nutrition-related scientific articles may bias conclusions in favor of sponsors' products, with potentially significant implications for public health.

  16. Automatically identifying health- and clinical-related content in wikipedia.

    Physicians are increasingly using the Internet for finding medical information related to patient care. Wikipedia is a valuable online medical resource to be integrated into existing clinical question answering (QA) systems. On the other hand, Wikipedia contains a full spectrum of world's knowledge and therefore comprises a large partition of non-health-related content, which makes disambiguation more challenging and consequently leads to large overhead for existing systems to effectively filter irrelevant information. To overcome this, we have developed both unsupervised and supervised approaches to identify health-related articles as well as clinically relevant articles. Furthermore, we explored novel features by extracting health related hierarchy from the Wikipedia category network, from which a variety of features were derived and evaluated. Our experiments show promising results and also demonstrate that employing the category hierarchy can effectively improve the system performance.

    The proliferation of biomedical literature makes it increasingly difficult for researchers to find and manage relevant information. However, identifying research articles containing mutation data, a requisite first step in integrating large and complex mutation data sets, is currently tedious, time-consuming and imprecise. More effective mechanisms for identifying articles containing mutation information would be beneficial both for the curation of mutation databases and for individual researchers. We developed an automated method that uses information extraction, classifier, and relevance ranking techniques to determine the likelihood of MEDLINE abstracts containing information regarding genomic variation data suitable for inclusion in mutation databases. We targeted the CDKN2A (p16) gene and the procedure for document identification currently used by CDKN2A Database curators as a measure of feasibility. A set of abstracts was manually identified from a MEDLINE search as potentially containing specific CDKN2A mutation events. A subset of these abstracts was used as a training set for a maximum entropy classifier to identify text features distinguishing "relevant" from "not relevant" abstracts. Each document was represented as a set of indicative word, word pair, and entity tagger-derived genomic variation features. When applied to a test set of 200 candidate abstracts, the classifier predicted 88 articles as being relevant; of these, 29 of 32 manuscripts in which manual curation found CDKN2A sequence variants were positively predicted. Thus, the set of potentially useful articles that a manual curator would have to review was reduced by 56%, maintaining 91% recall (sensitivity) and more than doubling precision (positive predictive value). Subsequent expansion of the training set to 494 articles yielded similar precision and recall rates, and comparison of the original and expanded trials demonstrated that the average precision improved with the larger data set

    Newspapers have immense potential for generating health awareness on diverse issues such as hygiene, immunization, environmental pollution, and communicable disease. The present study was conducted to determine the frequency of coverage and types of health-related articles published in local newspapers of Manipur. This was a cross-sectional study conducted among the most regularly published 10 local newspapers (4 English and 6 Manipuri) of Manipur from February 2011 to January 2012. Health-related articles published in everyday local newspapers were collected after careful search and finally entered into a design Proforma under different categories. Data were analyzed using SPSS version 16. Total health-related articles published were 10,874 and maximum articles were published during February (12.8%). Maximum health-related articles were published on Wednesday (16.1%). Among all the health-related articles, almost half were related with injury followed by public health articles. Maximum public health and injury-related articles were published on Monday, but medical topics were published more on Wednesday. Newspapers of both the languages were publishing public health articles more compared to medical topics. Public health (72.9%) and injury-related articles (95.9%) were published maximum in the news items section, but medical topics (45.8%) were published maximum in the health section of the newspaper. Newspapers of both the languages published maximum small size articles. There is a room for improvement for newspapers of both the languages regarding number of health-related articles' publication, section of publication, and size of the health articles.

    Wikipedia is one of the most accessed sources of health information online. The current English-language Wikipedia contains more than 28,000 articles pertaining to health. The aim was to characterize individuals' motivations for contributing to health content on the English-language Wikipedia. A set of health-related articles were randomly selected and recent contributors invited to complete an online questionnaire and follow-up interview (by Skype, by email, or face-to-face). Interviews were transcribed and analyzed using thematic analysis and a realist grounded theory approach. A total of 32 Wikipedians (31 men) completed the questionnaire and 17 were interviewed. Those completing the questionnaire had a mean age of 39 (range 12-59) years; 16 had a postgraduate qualification, 10 had or were currently studying for an undergraduate qualification, 3 had no more than secondary education, and 3 were still in secondary education. In all, 15 were currently working in a health-related field (primarily clinicians). The median period for which they have been an active editing Wikipedia was 3-5 years. Of this group, 12 were in the United States, 6 were in the United Kingdom, 4 were in Canada, and the remainder from another 8 countries. Two-thirds spoke more than 1 language and 90% (29/32) were also active contributors in domains other than health. Wikipedians in this study were identified as health professionals, professionals with specific health interests, students, and individuals with health problems. Based on the interviews, their motivations for editing health-related content were summarized in 5 strongly interrelated categories: education (learning about subjects by editing articles), help (wanting to improve and maintain Wikipedia), responsibility (responsibility, often a professional responsibility, to provide good quality health information to readers), fulfillment (editing Wikipedia as a fun, relaxing, engaging, and rewarding activity), and positive attitude to

    Objectives A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. Setting A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Main outcome measures Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. Results The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. Conclusions The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. PMID:25694457

There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. Published by the BMJ Publishing Group Limited.

    Kumar, K. V. S. H; Aravinda, Konidena

    2012-01-01

    Background: The details about the research productivity in the specialty of endocrinology from India is lacking. We plan to assess the publishing trends and the research productivity of Endocrinology related research articles published in the Journal of the Association of Physicians of India (JAPI). Materials and Methods: We carried the bibliometric analysis of endocrinology related articles from JAPI. The data were obtained from the JAPI website for the publications between 2000 and 2011. The articles were analyzed for the type (original article, case reports, correspondence, and pictorial image), subspecialty (diabetes, thyroid, etc.), and place of the research. Data were presented with descriptive statistics in numbers and percentages. Results: Out of a total 2977 articles published by JAPI, 312 articles belong to endocrine subspecialty. Endocrinology related articles constitute about 11.2%–23.2% of the published articles per year in JAPI and the percentage is increasing every year. Original articles (52%) and case reports (27%) constituite the majority, while the rest were letters to editor (9%) and pictorial images (12%). Diabetes (57%) and metabolic bone disorders (16%) lead the subspecialty articles, followed by thyroid (9%), adrenal and gonad (8%), and pituitary (8%). Chennai (20%), Mumbai (14%), and Delhi (9%) are the top 3 places contributing to the articles followed by Chandigarh and Varanasi. Conclusion: Majority of endocrinology related research productivity is seen in form of original articles and case reports. Diabetes is the leading disease with maximum research articles from Chennai and other glands are equally represented in the research productivity. PMID:23226637

    Despite their recognized limitations, bibliometric assessments of scientific productivity have been widely adopted. We describe here an improved method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. Article citation rates are divided by an expected citation rate that is derived from performance of articles in the same field and benchmarked to a peer comparison group. The resulting Relative Citation Ratio is article level and field independent and provides an alternative to the invalid practice of using journal impact factors to identify influential papers. To illustrate one application of our method, we analyzed 88,835 articles published between 2003 and 2010 and found that the National Institutes of Health awardees who authored those papers occupy relatively stable positions of influence across all disciplines. We demonstrate that the values generated by this method strongly correlate with the opinions of subject matter experts in biomedical research and suggest that the same approach should be generally applicable to articles published in all areas of science. A beta version of iCite, our web tool for calculating Relative Citation Ratios of articles listed in PubMed, is available at https://icite.od.nih.gov.

    There is a paucity of information about the dental specialties related articles published in the Medical Journal Armed Forces India (MJAFI). This study aimed to audit the dental specialities related articles published in MJAFI from 2000 to 2014 over a 15-year period. Bibliometric analysis of sixty issues of MJAFI from 2000 to 2014 were performed using web-based search. The articles published were analyzed for type of article and topic of individual dental specialities. The articles published were also evaluated to identify whether the study was an Armed Forces Medical Research Committee Project or funded research project or not. Out of the total 118 published articles related to dental specialities, original articles (55) and case reports (49) contribute the major share. The highest number of dental specialities related articles was published in 2009 with 16, followed by 2010 with 13 and 2011 with 11 and the least published year was 2013 with 3 articles. Regarding the relationship with dental specialities, the maximum number of published articles were related to oral medicine and radiology (56) followed by oral and maxillofacial surgery (49), orthodontics (23) and prosthodontics (17). Among the articles published in MJAFI, maxillofacial injuries (11) followed by orthodontic treatment (8) and craniofacial deformities (8) form the major attraction of the contributors. Among the 118 dental speciality articles, there were only 4 Armed Forces Medical Research Committee Project articles and 19 funded research project articles. An equal distribution of articles related to clinical dentistry and nonclinical dentistry is maintained for the MJAFI from 2000 to 2014 over a 15-year period.

    It is important to identify separate publications that report outcomes from the same underlying clinical trial, in order to avoid over-counting these as independent pieces of evidence. We created positive and negative training sets (comprised of pairs of articles reporting on the same condition and intervention) that were, or were not, linked to the same clinicaltrials.gov trial registry number. Features were extracted from MEDLINE and PubMed metadata; pairwise similarity scores were modeled using logistic regression. Article pairs from the same trial were identified with high accuracy (F1 score=0.843). We also created a clustering tool, Aggregator, that takes as input a PubMed user query for RCTs on a given topic, and returns article clusters predicted to arise from the same clinical trial. Although painstaking examination of full-text may be needed to be conclusive, metadata are surprisingly accurate in predicting when two articles derive from the same underlying clinical trial.

    The study of classic papers permits analysis of the past, present, and future of a specific area of knowledge. This type of analysis is becoming more frequent and more sophisticated. Our objective was to use the H-classics method, based on the h-index, to analyze classic papers in Implant Dentistry, Periodontics, and Oral Surgery (ID, P, and OS). First, an electronic search of documents related to ID, P, and OS was conducted in journals indexed in Journal Citation Reports (JCR) 2014 within the category 'Dentistry, Oral Surgery & Medicine'. Second, Web of Knowledge databases were searched using Mesh terms related to ID, P, and OS. Finally, the H-classics method was applied to select the classic articles in these disciplines, collecting data on associated research areas, document type, country, institutions, and authors. Of 267,611 documents related to ID, P, and OS retrieved from JCR journals (2014), 248 were selected as H-classics. They were published in 35 journals between 1953 and 2009, most frequently in the Journal of Clinical Periodontology (18.95%), the Journal of Periodontology (18.54%), International Journal of Oral and Maxillofacial Implants (9.27%), and Clinical Oral Implant Research (6.04%). These classic articles derived from the USA in 49.59% of cases and from Europe in 47.58%, while the most frequent host institution was the University of Gothenburg (17.74%) and the most frequent authors were J. Lindhe (10.48%) and S. Socransky (8.06%). The H-classics approach offers an objective method to identify core knowledge in clinical disciplines such as ID, P, and OS. © 2016 John Wiley & Sons A/S.

    This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

    Background: Citation metrics and total publications in a field has become the gold standard for rating researchers and viability of a field. Hence, stimulating demand for citation has led to a search for useful strategies to improve performance metric index. Meanwhile, title, abstract and morphologic qualities of the articles attract researchers to scientific publications. Yet, there is relatively little understanding of the citation trend in disability related fields. We aimed to provide an insight into the factors associated with citation increase in this field. Additionally, we tried to know at what page number an article might appear attractive to disability researchers needs. Thus, our focus is placed on the article page count and the number of authors contributing to the fields per article. Methods: To this end, we evaluated the quantitative characteristics of top cited articles in the fields with a total citation (≥50) in the Web of Science (WoS) database. Using one-way independent ANOVA, data extracted spanning a period of 1980–2015 were analyzed, while the non-parametric data analysis uses Kruskal-Walis test. Results: Articles with 11 to 20 pages attract more citations followed by those within the range of zero to 10. Articles with upward 21 pages are the least cited. Surprisingly, articles with more than two authors are significantly (P<0.05) less cited and the citation decreases as the number of authors increased. Conclusion: Collaborative studies enjoy wider utilization and more citation, yet discounted merit of additional pages and limited collaborative research in disability field is revealed in this study.

    The aim of this study is to investigate the relationships between citations and the scientific argumentation found abstracts. We design a related article search task and observe how the argumentation can affect the search results. We extracted citation lists from a set of 3200 full-text papers originating from a narrow domain. In parallel, we recovered the corresponding MEDLINE records for analysis of the argumentative moves. Our argumentative model is founded on four classes: PURPOSE, METHODS, RESULTS and CONCLUSION. A Bayesian classifier trained on explicitly structured MEDLINE abstracts generates these argumentative categories. The categories are used to generate four different argumentative indexes. A fifth index contains the complete abstract, together with the title and the list of Medical Subject Headings (MeSH) terms. To appraise the relationship of the moves to the citations, the citation lists were used as the criteria for determining relatedness of articles, establishing a benchmark; it means that two articles are considered as "related" if they share a significant set of co-citations. Our results show that the average precision of queries with the PURPOSE and CONCLUSION features is the highest, while the precision of the RESULTS and METHODS features was relatively low. A linear weighting combination of the moves is proposed, which significantly improves retrieval of related articles.

    Protein-protein interaction (PPI) is an important biomedical phenomenon. Automatically detecting PPI-relevant articles and identifying methods that are used to study PPI are important text mining tasks. In this study, we have explored domain independent features to develop two open source machine learning frameworks. One performs binary classification to determine whether the given article is PPI relevant or not, named "Simple Classifier", and the other one maps the PPI relevant articles with corresponding interaction method nodes in a standardized PSI-MI (Proteomics Standards Initiative-Molecular Interactions) ontology, named "OntoNorm". We evaluated our system in the context of BioCreative challenge competition using the standardized data set. Our systems are amongst the top systems reported by the organizers, attaining 60.8% F1-score for identifying relevant documents, and 52.3% F1-score for mapping articles to interaction method ontology. Our results show that domain-independent machine learning frameworks can perform competitively well at the tasks of detecting PPI relevant articles and identifying the methods that were used to study the interaction in such articles. Simple Classifier is available at http://sourceforge.net/p/simpleclassify/home/ and OntoNorm at http://sourceforge.net/p/ontonorm/home/.

    2016-01-01

    Research waste occurs when research is ignored, cannot be found, cannot be used, or is unintentionally repeated. This article aims to investigate how dental survival analyses were indexed and reported, and to discuss whether errors in indexing and writing articles are affecting identification and use of survival articles, contributing to research waste. Articles reporting survival of dental prostheses in humans (also known as time-to-event) were identified by searching 50 dental journals that had the highest Impact Factor in 2008. These journals were hand searched twice (Kappa 0.92), and the articles were assessed by two independent reviewers (Kappa 0.86) to identify dental survival articles ("case" articles, n = 95), likely false positives (active controls, n = 91), and all other true negative articles (passive controls, n = 6,769). This means that the study used a case:control method. Once identified, the different groups of articles were assessed and compared. Allocation of medical subject headings (MeSH) by MEDLINE indexers that related to survival was sought, use of words by authors in the abstract and title that related to survival was identified, and use of words and figures by authors that related to survival in the articles themselves was also sought. Differences were assessed with chi-square and Fisher's Exact statistics. Reporting quality was also assessed. The results were reviewed to discuss their potential impact on research waste. Allocation of survival-related MeSH index terms across the three article groups was inconsistent and inaccurate. Statistical MeSH had not been allocated to 30% of the dental survival "case" articles and had been incorrectly allocated to 15% of active controls. Additionally, information reported by authors in titles and abstracts varied, with only two-thirds of survival "case" articles mentioning survival "statistics" in the abstract. In the articles themselves, time-to-event statistical methods, survival curves, and life

    The total citations that a peer-reviewed manuscript has is often used to measure the impact that a publication has in its respective field of study. Both the citation count and total number of publications are often used as measures of academic productivity and success. This issue has been previously investigated in the field of tobacco control research. Given the changing landscape in the field of tobacco research since 2004, we sought to re-examine this issue. The study purpose was to identify the 100 top-cited tobacco-related articles published since 2005, and to categorize and describe the fields of study represented in these articles. We searched the Scopus library database to determine the citations of the top 100 tobacco-related articles. Information was gathered on: title, number of authors, publication year, journal name and impact factor, country of origin, article type and subject category. Articles were selected and analyzed by two independent investigators. We identified the 100 top-cited articles published in 58 journals, led by The New England Journal of Medicine (8) and Lancet (6), between 2005 and 2014. The United States was the most common country of origin for the highly-cited articles. The top article types were observation (27%), basic science (26%), and review articles (24%). The most common article subject area was medicine (74%). A statistically significant association was found between the journal impact factor and the number of top 100 cited articles ( p = 0.03). This review may be helpful to identify articles that may be contributing to the conduct of current and future tobacco research. The analysis can be used as a reference to review and evaluate the publications that are making a high impact in the field of tobacco research.

We extracted terms and concepts from a data set of 72,469 ClinicalTrials.gov registrations and 276,307 PubMed articles and tested methods for ranking articles across 16,005 reported links and 90 manually identified unreported links. Performance was measured by the median rank of matching articles and the proportion of unreported links that could be found by screening ranked candidate articles in order. The best-performing concept-based representation produced a median rank of 3 (interquartile range [IQR] 1-21) for reported links and 3 (IQR 1-19) for the manually identified unreported links, and term-based representations produced a median rank of 2 (1-20) for reported links and 2 (IQR 1-12) in unreported links. The matching article was ranked first for 40% of registrations, and screening 50 candidate articles per registration identified 86% of the unreported links. Leveraging the growth in the corpus of reported links between ClinicalTrials.gov and PubMed, we found that document similarity methods can assist in the identification of unreported links between trial registrations and corresponding articles.

    This data aimed to audit the dental sciences related articles published in Iranian Journal of Basic Medical Sciences (IJBMS) from 2007 to 2015 over a 9 year period performed using web-based search. The data were analyzed for topic of dental sciences, type of article, international collaborations, source of funding, number of authors and authorship trends. Out of the total 18 data related to dental sciences, original articles (12), review articles (4) and short communications (2) contribute the major share. Regarding the relationship with dental sciences, the maximum number of data were related to oral pathology and microbiology (16) followed by oral medicine and radiology (7) and periodontics (7). Among the data related to dental sciences, oral cancer (3) and gingival and periodontal diseases (3) followed by dental plaque and caries (2) and orthodontic tooth movement (2) form the major attraction of the contributors. The largest numbers of data related to dental sciences were received from Mashhad University of Medical Sciences, Mashhad (4) and Tehran University of Medical Sciences,Tehran (2).The present data were compared with previous bibliometric studies done related to dental sciences (Shamim et al., 2017a, 2017b).

    Introduction Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. Methods Two searches were conducted in the Web of Science in June 2016 using a list of education-related search terms. We searched 19 EM journals for education articles as well as all other literature for EM education-related articles. Articles identified were reviewed for citation count, article type, journal, authors, and publication year. Results With regards to EM journals, the greatest number of articles were classified as articles/reviews, followed by research articles on topics such as deliberate practice (cited 266 times) and cognitive errors (cited 201 times). In contrast in the non-EM journals, research articles were predominant. Both searches found several simulation and ultrasound articles to be included. The most common EM journal was Academic Emergency Medicine (n = 18), and Academic Medicine was the most common non-EM journal (n=5). A reasonable number of articles included external funding sources (6 EM articles and 13 non-EM articles.) Conclusion This study identified the most frequently cited medical education articles in the field of EM education, published in EM journals as well as all other journals indexed in Web of Science. The results identify impactful articles to medical education, providing a resource to educators while identifying trends that may be used to guide EM educational research and publishing efforts.

    Several indicators have been used to analyze scientific journals, with the impact factor and the number of citations in a 2-yr calendar time frame (2-YRC) being the most common factors. However, considering that the Journal of Applied Physiology (JAPPL) appears monthly and that calculations of these indicators are based on citations of papers published in previous years, we hypothesized that articles published at the beginning of the year would be cited more in the 2-YRC compared with those appearing in the last issues of the year, a phenomena known as a relative age effect. Our objective was to confirm the existence of a relative age effect in the 2-YRC for original articles published in JAPPL. From 2005 to 2008, a total of 1,726 original articles were published, according to the Web of Science, and 9,973 citations in 2-YRC, varying from 0 to 45, with a mean of 5.78 for individual papers. Although there were no differences in the number of original articles published in a given month (P = 0.99), the 2-YRC varied considerably throughout the year, being higher for those earlier issues of the year, as shown by the linear regression analysis (r(2) = 0.76; P < 0.001). The 2-YRC began at 6.62 during the first 3 mo of the year, dropping by 10% at each 3-mo period. In summary, the longer an article has been out there, the more citations it collects. The relative age effect is a potential confounding variable for the assessment and interpretation of 2-YRC (using calendar years) from JAPPL original articles.

    To design optimal search strategies for locating sound therapy studies and review articles in CiNAHL in the year 2000. An analytic survey was conducted, comparing hand searches of 75 journals with retrievals from CINAHL for 5,020 candidate search terms and 17,900 combinations for therapy and 5,977 combinations for review articles. All articles were rated with purpose and quality indicators. Candidate search strategies were used in CINAHL, and the retrievals were compared with results of the hand searches. The proposed search strategies were treated as "diagnostic tests" for sound studies and the manual review of the literature was treated as the "gold standard." Operating characteristics of the search strategies were calculated. Of the 1,383 articles about treatment, 506 (36.6%) met basic criteria for scientific merit and 127 (17.9%) of the 711 articles classified as a review met the criteria for systematic reviews. For locating sound treatment studies, a three-term strategy maximized sensitivity at 99.4% but with compromised specificity at 58.3%, and a two-term strategy maximized specificity at 98.5% but with compromised sensitivity at 52.0%. For detecting systematic reviews, a three-term strategy maximized sensitivity at 91.3% while keeping specificity high at 95.4%, and a single-term strategy maximized specificity at 99.6% but with compromised sensitivity at 42.5%. Three-term search strategies optimizing sensitivity and specificity achieved these values over 91% for detecting sound treatment studies and over 76% for detecting systematic reviews. Search strategies combining indexing terms and text words can achieve high sensitivity and specificity for retrieving sound treatment studies and review articles in CINAHL.

    Wind tunnels have been widely employed in aerodynamic research. To characterize the high impact research, a bibliometric analysis was conducted on highly cited articles related to wind tunnel based on the Science Citation Index Expanded (SCI-EXPANDED) database from 1900 to 2014. Articles with at least 100 citations from the Web of Science Core Collection were selected and analyzed in terms of publication years, authors, institutions, countries/territories, journals, Web of Science categories, and citation life cycles. The results show that a total of 77 highly cited articles in 37 journals were published between 1959 and 2008. Journal of Fluid Mechanics published the most of highly cited articles. The USA was the most productive country and most frequent partner of internationally collaboration. The prolific institutions were mainly located in the USA and UK. The authors who were both first author and corresponding author published 88% of the articles. The Y index was also deployed to evaluate the publication characteristics of authors. Moreover, the articles with high citations in both history and the latest year with their citation life cycles were examined to provide insights for high impact research. The highly cited articles were almost earliest wind tunnel experimental data and reports on their own research specialty, and thus attracted high citations. It was revealed that classic works of wind tunnel research was frequently occurred in 1990s but much less in 2000s, probably due to the development of numerical models of computational fluid dynamic (CFD) in recent decades.

    Citation analysis helps to identify the research trends within a research field and helps to identify the most frequently occurring parameters. The aim of this study was to identify the 100 most-cited articles in the field of dental, oral, and maxillofacial traumatology over the past 64 years. A comprehensive list of the most-cited articles in dental, oral, and maxillofacial trauma was compiled using 'All Databases' section of the ISI Web of Knowledge. Related articles were considered to be those articles in which part or all of the experiment or study was related to dental and/or oral and maxillofacial trauma. In case reports, if a part of a treatment plan was related to the topic, that article was considered to be relevant. The characteristics analyzed included number of citations, authors, journals, institution, country of origin, publication year, article type, study material, and topic. The number of citations for each article ranged from 69 to 229. The journal Dental Traumatology was the most represented, followed by the journal Oral and Maxillofacial Surgery. Of the 100 articles, 83% were original articles, 15% were review articles, and 2% were case report/case series. Therapy and prognosis-related topics were the most common topics. Most articles came from institutions in the United States, followed by the Scandinavian countries. University Hospital of Copenhagen was the source of the highest number (34) of the most-cited articles; the same author wrote or co-wrote 22 of the 100 most-cited articles. The list of most-cited articles in the field of dental, oral, and maxillofacial traumatology gives a good scientometric picture of trauma research in the world. A large number of the most-cited articles are mainly from the field of dental traumatology and originate from a few research teams. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Complementary and alternative medicine (CAM) therapy has gained popularity in America over the past several years, reflected in the increased utilization of these agents. Given the abundance of nontraditional products available to the public, clinicians should be made aware of the existing evidence relating to CAM therapy to better provide patient care in a meaningful manner. This bibliography paper compiled key articles specific to CAM therapy and cardiovascular disease, which include primary literature, review articles, consensus statements, and abstracts of landmark studies. Based on the numerous published reports available on this topic, this bibliography, as part I of II, focuses on the efficacy of CAM therapy in cardiovascular disease. PMID:20030478

    2012-01-01

    To compare and estimate the magnitude of work-related motor vehicle crashes in Utah using 2 probabilistically linked statewide databases. Data from 2006 and 2007 motor vehicle crash and hospital databases were joined through probabilistic linkage. Summary statistics and capture-recapture were used to describe occupants injured in work-related motor vehicle crashes and estimate the size of this population. There were 1597 occupants in the motor vehicle crash database and 1673 patients in the hospital database identified as being in a work-related motor vehicle crash. We identified 1443 occupants with at least one record from either the motor vehicle crash or hospital database indicating work-relatedness that linked to any record in the opposing database. We found that 38.7 percent of occupants injured in work-related motor vehicle crashes identified in the motor vehicle crash database did not have a primary payer code of workers' compensation in the hospital database and 40.0 percent of patients injured in work-related motor vehicle crashes identified in the hospital database did not meet our definition of a work-related motor vehicle crash in the motor vehicle crash database. Depending on how occupants injured in work-related motor crashes are identified, we estimate the population to be between 1852 and 8492 in Utah for the years 2006 and 2007. Research on single databases may lead to biased interpretations of work-related motor vehicle crashes. Combining 2 population based databases may still result in an underestimate of the magnitude of work-related motor vehicle crashes. Improved coding of work-related incidents is needed in current databases.

    Tongue tie or ankyloglossia articles are recorded in the Medline since 1949. To study trends in yearly number of tongue tie or ankyloglossia publications. Medline search engine was used to determine the yearly number of published consensus statements from 1949 to 2016. Keywords of tongue tie OR ankyloglossia OR frenotomy OR frenulotomy were used for the search. Articles were classified as case reports (or series), reviews, editorials (or opinions), cohort studies, clinical trials (nonrandomized), randomized controlled trials (RCT), and systematic reviews (SR). Linear or polynomial regression was used to determine trends. We also systematically summarized all RCTs published to date. The total number of yearly published articles increased in a cubic fashion (r 2  = 82.6%, p < 0.0001) over time (0-7 per year from 1949 to 1989, and up to 27-44 in the last 5 years). In terms of strength of evidence hierarchy, most articles belonged to low hierarchy categories (case reports 37.9%, reviews 15.4%, and editorials/opinions 13.4%), with only 8 RCTs and 10 SRs (all of them published during the last 10 years of the study period). The yearly number of tongue tie or ankyloglossia-related articles has increased dramatically in past few years. Most articles bring little evidence, but the past few years have witnessed publication of few RCTs and SRs. If this trend continues, much more solid evidence should accumulate about diagnosis and management of tongue tie, as it relates to breastfeeding and other outcomes.

  18. Tracking Multiple Topics for Finding Interesting Articles

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able tomore » achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.« less

  19. Passage-Based Bibliographic Coupling: An Inter-Article Similarity Measure for Biomedical Articles

    PubMed Central

    Liu, Rey-Long

    2015-01-01

    Biomedical literature is an essential source of biomedical evidence. To translate the evidence for biomedicine study, researchers often need to carefully read multiple articles about specific biomedical issues. These articles thus need to be highly related to each other. They should share similar core contents, including research goals, methods, and findings. However, given an article r, it is challenging for search engines to retrieve highly related articles for r. In this paper, we present a technique PBC (Passage-based Bibliographic Coupling) that estimates inter-article similarity by seamlessly integrating bibliographic coupling with the information collected from context passages around important out-link citations (references) in each article. Empirical evaluation shows that PBC can significantly improve the retrieval of those articles that biomedical experts believe to be highly related to specific articles about gene-disease associations. PBC can thus be used to improve search engines in retrieving the highly related articles for any given article r, even when r is cited by very few (or even no) articles. The contribution is essential for those researchers and text mining systems that aim at cross-validating the evidence about specific gene-disease associations. PMID:26440794

    2017-10-01

    Named entities such as people, locations, and organizations play a vital role in characterizing online content. They often reflect information of interest and are frequently used in search queries. Although named entities can be detected reliably from textual content, extracting relations among them is more challenging, yet useful in various applications (e.g., news recommending systems). In this paper, we present a novel model and system for learning semantic relations among named entities from collections of news articles. We model each named entity occurrence with sparse structured logistic regression, and consider the words (predictors) to be grouped based on background semantics. This sparse group LASSO approach forces the weights of word groups that do not influence the prediction towards zero. The resulting sparse structure is utilized for defining the type and strength of relations. Our unsupervised system yields a named entities' network where each relation is typed, quantified, and characterized in context. These relations are the key to understanding news material over time and customizing newsfeeds for readers. Extensive evaluation of our system on articles from TIME magazine and BBC News shows that the learned relations correlate with static semantic relatedness measures like WLM, and capture the evolving relationships among named entities over time.

    The aim of this study was to identify and analyze the top 50 most cited articles in cartilage regeneration. The impact of a scientific journal can be gauged by the total number of citations it has accrued. The top 50 most cited articles involving cartilage regeneration represent the most quoted level of evidence among this new subspecialty. This study aims to identify and analyze the 50 most cited articles in cartilage regeneration. The Web of Science™ citation indexing service was utilized to determine the most frequently cited articles published after 1956 containing "cartilage regeneration" in the "topic" or "title." The 50 most cited articles were included. The number of citations, year of publication, country of article origin, article institution, journal of publication, publication format, and authorship were then calculated for each article. The span of citations ranged from 1287 to 203 citations, with a mean of 361.02 citations per article in question. The articles originated from 11 countries, with the United States contributing 34 articles, followed by Japan with 5 articles. The articles were distributed across 34 high-impact journals. Biomaterials was the journal with the highest number of publications (seven articles) followed by the Journal of Orthopaedic Research (three articles). Of the 50 articles, 2 were clinical observational studies, 47 concerned basic science, and 1 was review article. The most cited articles involving cartilage regeneration are detected in both experimental and clinical research fields. The high ratio of basic science to clinical articles reflects the infancy of this relatively new specialty and that further clinical research is required in this area.

    The field of pain-related research has gained more attention as the prevalence of chronic pain increased over the years. The objective of this research was to identify highly cited papers, as well as contributors, to pain-related research. Pain-related articles published from 1900 to 2011 were screened, and highly cited papers, with at least 100 citations since publication, were identified and selected for a bibliometric analysis. The total number of papers, authorship, and collaboration statistics are presented for countries, institutions, and authors. To assess contributions, a new indicator, the major contributor index (MCI), was used. Citation trends for all papers, as well as for top papers, are presented. A total of 7,327 articles, 2.4% of all pain related articles, had received at least 100 citations since publication. In recent decades, top-cited articles have reached a citation peak more quickly, and have shown a more-rapid decreasing trend, compared with top-cited articles from earlier decades. The leading countries were United States, U.K., Canada, and Germany. The leading institutions were Harvard University, University of California, San Francisco, University of Texas, and University of Washington. MCI varied among leading institutions, as well as among individual authors. An indicator like the MCI can provide a proxy for the contributions made by an individual or institution. It reflects the independent research ability and leadership. In future evaluations of institution or individual performances, the MCI should be included, together with the number of total papers, to provide a better profile of research performance.

    Identification of highly cited articles based on the h-index and its properties is important for the evaluation of the past, present, and future of any research discipline. In this study, we aimed to identify the h-classic articles in orthodontics. One search on the Web of Science identified all articles from 2000 to 2015 in the 89 journals indexed by the 2015 InCites Journal Citation Reports in the scientific area "dentistry, oral surgery, and medicine." A second search was performed in the Web of Science using all mesh terms related to orthodontics. Then, we applied the h-classic method to select the recent articles with the greatest scientific impact in orthodontics. Eighty articles were considered as h-classic articles. They were published in 20 of the 89 dental journals of the 2015 InCites Journal Citation Reports list. Only 36 articles appeared in orthodontic journals: 23 in the American Journal of Orthodontics & Dentofacial Orthopedics (28.8%), 7 in The Angle Orthodontist (8.8%), and 6 in European Journal of Orthodontics (7.5%). Thirty-eight articles originated from Europe, 28 from the Americas, and 14 from the Middle East and Asia. More than half of fundamental orthodontic research is published in nonorthodontic journals showing that our field is currently limited, and interactions with other research fields should be sought to increase orthodontic research importance and appeal.

    The purpose of this study was to identify and examine the top 100 most highly cited articles of all time as well as the 25 most highly cited articles of the last decade from within 5 school psychology journals: Journal of School Psychology, Psychology in the Schools, School Psychology International, School Psychology Quarterly, and School Psychology Review. The Institute for Scientific Information Web of Science database was utilized to identify citation counts for each article appearing in these journals. Coding schemes were used to identify article type and content area. The top 10 most highly cited articles of all time as well as the top 10 most highly cited articles of the past decade are detailed, and general patterns found across these articles are discussed. Implications for reviewing manuscripts that are likely to become highly cited articles and for authoring a highly cited article are offered. Copyright © 2011. Published by Elsevier Ltd.

  8. PubMed related articles: a probabilistic topic-based model for content similarity

    Background We present a probabilistic topic-based model for content similarity called pmra that underlies the related article search feature in PubMed. Whether or not a document is about a particular topic is computed from term frequencies, modeled as Poisson distributions. Unlike previous probabilistic retrieval models, we do not attempt to estimate relevance–but rather our focus is "relatedness", the probability that a user would want to examine a particular document given known interest in another. We also describe a novel technique for estimating parameters that does not require human relevance judgments; instead, the process is based on the existence of MeSH ® in MEDLINE ®. Results The pmra retrieval model was compared against bm25, a competitive probabilistic model that shares theoretical similarities. Experiments using the test collection from the TREC 2005 genomics track shows a small but statistically significant improvement of pmra over bm25 in terms of precision. Conclusion Our experiments suggest that the pmra model provides an effective ranking algorithm for related article search. PMID:17971238

    Abstract Aims: To identify and characterize the top-cited articles in the field of islet transplantation. Methods: We used the Science Citation Index Expanded database to identify the most frequently cited articles published after 1900. Articles were evaluated using the following characteristics: citation number, publication year, study design, references, country and institution of origin, authorship, and journal. Keyword analysis and citation networks were used to analyze research trends. Results: The most frequently cited articles received between 146 and 2988 citations; the median was 291. All of the most frequently cited articles were published between 1972 and 2012, and 85 articles were published after 1990. The most popular study design involved basic science (75 articles). The leading countries were the United States (US) and Canada, and the leading institutions were the University of Alberta, Canada, and the University of Minnesota, in the US. Journals specializing in diabetes or transplantation published more than half of the articles (n = 53, 52%), with the journal Diabetes publishing the largest number (n = 30). No association was found between a journal's impact factor and the number of top-cited articles it published. There was no correlation between the number of citations and the number of years since publication, authors, participating institutions, or countries involved. Top-cited articles focused on 2 themes: the use of antirejection immunotherapy or biocompatible encapsulations to prolong graft survival, and assessments of the efficacy of islet transplants, in particular, islet allografts. Conclusions: Our study can help researchers to identify and decipher the characteristics of top-cited articles in the field of islet transplantation. Just as clinically successful allografts are carried out using the Edmonton protocol, autografts and xenografts should be similarly strengthened to solve problems relating to immune rejection and islet

    Do citations accumulate too slowly in the social sciences to be used to assess the quality of recent articles? I investigate whether this is the case using citation data for all articles in economics and political science published in 2006 and indexed in the Web of Science. I find that citations in the first two years after publication explain more than half of the variation in cumulative citations received over a longer period. Journal impact factors improve the correlation between the predicted and actual future ranks of journal articles when using citation data from 2006 alone but the effect declines sharply thereafter. Finally, more than half of the papers in the top 20% in 2012 were already in the top 20% in the year of publication (2006).

    Background Cardiology fellowship programs are at the interface of medical education and the care of patients suffering from the leading cause of mortality in the United States, yet there is an apparent lack of research guiding the effective education of fellows. Objective We sought to quantify the number of publications in cardiology journals that pertained to the education of cardiology trainees and the number of cardiologists participating in education research. Methods For the period between January and December 2012, we cataloged cardiology-specific and general medical/medical education journals and sorted them by impact factor. Tables of content were reviewed for articles with an educational focus, a cardiology focus, or both. We recorded the authors' areas of medical training, and keywords from each cardiology journal's mission statement were reviewed for emphasis on education. Results Twenty-six cardiology journals, containing 6645 articles, were reviewed. Only 4 articles had education themes. Ten general medical and 15 medical education journals contained 6810 articles. Of these, only 7 focused on medical education in cardiology, and none focused on cardiology fellowship training. Among the 4887 authors of publications in medical education journals, 25 were cardiologists (less than 1%), and among the 1036 total words in the mission statements of all cardiology journals, the term “education” appeared once. Conclusions Published educational research is lacking in cardiology training, and few cardiologists appear to be active members of the education scholarship community. Cardiology organizations and academic journals should support efforts to identify target areas of study and publish scholarship in educational innovation. PMID:27413435

  15. Challenges for automatically extracting molecular interactions from full-text articles.

    2009-09-24

    The increasing availability of full-text biomedical articles will allow more biomedical knowledge to be extracted automatically with greater reliability. However, most Information Retrieval (IR) and Extraction (IE) tools currently process only abstracts. The lack of corpora has limited the development of tools that are capable of exploiting the knowledge in full-text articles. As a result, there has been little investigation into the advantages of full-text document structure, and the challenges developers will face in processing full-text articles. We manually annotated passages from full-text articles that describe interactions summarised in a Molecular Interaction Map (MIM). Our corpus tracks the process of identifying facts to form the MIM summaries and captures any factual dependencies that must be resolved to extract the fact completely. For example, a fact in the results section may require a synonym defined in the introduction. The passages are also annotated with negated and coreference expressions that must be resolved.We describe the guidelines for identifying relevant passages and possible dependencies. The corpus includes 2162 sentences from 78 full-text articles. Our corpus analysis demonstrates the necessity of full-text processing; identifies the article sections where interactions are most commonly stated; and quantifies the proportion of interaction statements requiring coherent dependencies. Further, it allows us to report on the relative importance of identifying synonyms and resolving negated expressions. We also experiment with an oracle sentence retrieval system using the corpus as a gold-standard evaluation set. We introduce the MIM corpus, a unique resource that maps interaction facts in a MIM to annotated passages within full-text articles. It is an invaluable case study providing guidance to developers of biomedical IR and IE systems, and can be used as a gold-standard evaluation set for full-text IR tasks.

    Examination of top-cited articles is a tool that can help to identify and monitor outstanding scientific researches and landmark papers. We aimed to identify the 100 most cited published papers in peer-reviewed biomedical journals in the field of digestive diseases and to examine their characteristics. The Web of Science (including Science Citation Index) was searched for the most cited papers related to digestive diseases, published from 1955 to the present. The top 100 most cited articles were identified. The number of citations, countries, and institutions of origin, year of publication, study design, topic, and levels of evidence of the articles were noted and analyzed. The most top-cited articles had a mean of 1375 citations. These articles were published between 1978 and 2009 in 29 high-impact journals, with the New England Journal of Medicine (n = 22) topping the list. Of the 100 articles, 34 were clinical studies, 15 were review articles, and 34 were concerned basic science. These articles came from 18 countries, with the USA contributing most of the top-cited articles (n = 53). Eighty-seven institutions produced these 100 top-cited articles, led by the University of Barcelona (n = 4). Seven persons authored two or more of these top-cited articles. The mostly represented specialty was gastrointestinal oncology (n = 49). Our study can give a historical perspective on the scientific progress of digestive diseases, as well as allow for recognition of most important advances in this area and provide useful information to guide future researches. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Objective To identify the 50 top-cited spine articles from mainland China and to analyze their main characteristics. Methods Web of Science was used to identify the 50 top-cited spine articles from mainland China in 27 spine-related journals. The title, year of publication, number of citations, journal, anatomic focus, subspecialty, evidence level, city, institution and author were recorded. Results The top 50 articles had 29-122 citations and were published in 11 English-language journals; most (32) were published in the 2000s. The journal Spine had the largest number of articles and The Lancet had the highest impact factor. The lumber spine was the most discussed anatomic area (18). Degenerative spine disease was the most common subspecialty topic (22). Most articles were clinical studies (29); the others were basic research (21). Level IV was the most common evidence level (17). Conclusions This list indicates the most influential articles from mainland China in the global spine research community. Identification of these articles provides insights into the trends in spine care in mainland China and the historical contributions of researchers from mainland China to the international spine research field.

    2018-02-01

    Reading scientific articles is a valuable and major part of the activity of scientists. Yet, with the upsurge of currently available articles and the increasing specialization of scientists, it becomes difficult to identify, let alone read, important papers covering topics not directly related to one's own specific field of research, or that are older than a few years. Our objective was to propose a list of seminal papers deemed to be of major importance in ecology, thus providing a general 'must-read' list for any new ecologist, regardless of particular topic or expertise. We generated a list of 544 papers proposed by 147 ecology experts (journal editorial members) and subsequently ranked via random-sample voting by 368 of 665 contacted ecology experts, covering 6 article types, 6 approaches and 17 fields. Most of the recommended papers were not published in the highest-ranking journals, nor did they have the highest number of mean annual citations. The articles proposed through the collective recommendation of several hundred experienced researchers probably do not represent an 'ultimate', invariant list, but they certainly contain many high-quality articles that are undoubtedly worth reading-regardless of the specific field of interest in ecology-to foster the understanding, knowledge and inspiration of early-career scientists.

    Nontargeted GC×GC-TOF/MS analysis of blubber from 8 common bottlenose dolphins (Tursiops truncatus) inhabiting the Southern California Bight was performed to identify novel, bioaccumulative DDT-related compounds and to determine their abundance relative to the commonly studied DDT-related compounds. We identified 45 bioaccumulative DDT-related compounds of which the majority (80%) is not typically monitored in environmental media. Identified compounds include transformation products, technical mixture impurities such as tris(chlorophenyl)methane (TCPM), the presumed TCPM metabolite tris(chlorophenyl)methanol (TCPMOH), and structurally related compounds with unknown sources, such as hexa- to octachlorinated diphenylethene. To investigate impurities in pesticide mixtures as possible sources of these compounds, we analyzed technical DDT, the primary source of historical contamination in the region, and technical Dicofol, a current use pesticide that contains DDT-related compounds. The technical mixtures contained only 33% of the compounds identified in the blubber, suggesting that transformation products contribute to the majority of the load of DDT-related contaminants in these sentinels of ocean health. Quantitative analysis revealed that TCPM was the second most abundant compound class detected in the blubber, following DDE, and TCPMOH loads were greater than DDT. QSPR estimates verified 4,4',4″-TCPM and 4,4'4,″-TCPMOH are persistent and bioaccumulative.

    The number of citations that an article has received reflects its impact on the scientific community. The purpose of our study was to identify and characterize the 51 most-cited articles in pediatric imaging. Based on the database of Journal Citation Reports, we selected 350 journals that were considered as potential outlets for pediatric imaging articles. The Web of Science search tools were used to identify the most-cited articles relevant to pediatric imaging within the selected journals. The 51 most-cited articles in pediatric imaging were published between 1952 and 2011, with 1980- 1989 and 2000-2009 producing 15 articles, each. The number of citations ranged from 576-124 and the number of annual citations ranged from 49.05-2.56. The majority of articles were published in pediatric and related journals (n=26), originated in the United States (n=23), were original articles (n=45), used MRI as imaging modality (n=27), and were concerned with the subspecialty of brain (n=34). University College London School of Medicine (n=6) and School of Medicine University of California (n=4) were the leading institutions and Reynolds EO (n=7) was the most voluminous author. Our study presents a detailed list and an analysis of the most-cited articles in the field of pediatric imaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

    Total Ankle Arthroplasty (TAA) is a relatively new and evolving field in Foot and Ankle surgery. We conducted a citation analysis to identify the characteristics of the top 50 most cited articles on total ankle arthroplasty. Using the Web of Science database and the search strategy total ankle arthroplasty OR total ankle replacement , we identified 2445 articles. After filtering for relevant articles, the top 50 cited articles on total ankle arthroplasty were retrieved for descriptive and statistical analysis. The publication years ranged from 1979 to 2013. USA was the most productive country in terms of research output, followed by the UK. Though citation analysis has its flaws, this is a comprehensive list of the top 50 articles significantly impacting literature on total ankle arthroplasty. Based on our study, we conclude that there is marked deficiency of high level articles with respect to the number of citations and future researches need to cater to this question to produce high quality studies.

    There have been few attempts to identify classic papers within the hand surgery literature. This study used citation analysis to identify and characterize the top 50 highly cited hand surgery articles published in six peer-reviewed journals. The 50 most highly cited hand surgery articles were identified in the Journal of Bone and Joint Surgery (JBJS) American, JBJS British, Plastic and Reconstructive Surgery, Journal of Hand Surgery (JHS) American, JHS British/European, and Hand. Articles were evaluated for citations per year, surgical/anatomical topic, and type of study. Clinical studies were further sub-categorized by level of evidence. The distribution of topics was compared with all indexed hand surgery articles. The educational relevance was assessed via comparison with lists of "classic" papers. The most common subjects were distal radius fracture, carpal tunnel syndrome, and flexor tendon repair. There was moderate correlation between the distribution of these topics and all indexed hand surgery articles (rho = 0.71). There were 31 clinical studies, of which 16 were therapeutic, ten were prognostic, and five were diagnostic. These articles assessed the outcomes of an intervention, described an anatomical/functional observation, introduced an innovation, presented a discovery/classification, or validated a questionnaire. There were only three randomized trials. Using citations per year to control for the influence of time since publication, 36 articles were consistently highly cited. Twenty-three articles were on Stern's Selected Readings in Hand Surgery, considered important in education. The top 50 highly cited articles in hand surgery reflect the most common clinical, scientific, and educational efforts of the field.

    Research on publication trends in journal articles on sleep disorders (SDs) and the associated methodologies by using text mining has been limited. The present study involved text mining for terms to determine the publication trends in sleep-related journal articles published during 2000-2013 and to identify associations between SD and methodology terms as well as conducting statistical analyses of the text mining findings. SD and methodology terms were extracted from 3,720 sleep-related journal articles in the PubMed database by using MetaMap. The extracted data set was analyzed using hierarchical cluster analyses and adjusted logistic regression models to investigate publication trends and associations between SD and methodology terms. MetaMap had a text mining precision, recall, and false positive rate of 0.70, 0.77, and 11.51%, respectively. The most common SD term was breathing-related sleep disorder, whereas narcolepsy was the least common. Cluster analyses showed similar methodology clusters for each SD term, except narcolepsy. The logistic regression models showed an increasing prevalence of insomnia, parasomnia, and other sleep disorders but a decreasing prevalence of breathing-related sleep disorder during 2000-2013. Different SD terms were positively associated with different methodology terms regarding research design terms, measure terms, and analysis terms. Insomnia-, parasomnia-, and other sleep disorder-related articles showed an increasing publication trend, whereas those related to breathing-related sleep disorder showed a decreasing trend. Furthermore, experimental studies more commonly focused on hypersomnia and other SDs and less commonly on insomnia, breathing-related sleep disorder, narcolepsy, and parasomnia. Thus, text mining may facilitate the exploration of the publication trends in SDs and the associated methodologies.

    Since the first description of Guillain-Barré syndrome (GBS) 100 years ago, the concept of this syndrome has changed remarkably. The purpose of our study was to identify and characterize the most-cited articles that have contributed to advancing the understanding of GBS. Based on the database of Journal Citation Reports, we selected 554 journals that were considered as potential sources of reports on studies related to clinical neurology and general medicine. The Web of Science search tools were used to identify the most-cited articles relevant to GBS or other variants in the selected journals. Of the selected articles, 18 were review articles and the remainder were original articles or included only a few case series. Among the original articles, 13 described basic research associated with immunological pathogenesis involving anti-ganglioside antibodies. Most of the original studies (42/64, 66%) published after 1990 evaluated anti-ganglioside antibodies that mediated axonal GBS or Miller Fisher syndrome, with only a small number of the papers involving electrodiagnostic medicine (n = 4). Our bibliometric analysis has yielded a detailed list of the top-100 cited articles in the field of GBS. © 2016 Peripheral Nerve Society.

    To compare Spanish nursing journals with 2 English-language standard journals, as well as Spanish journals in closely related disciplines, to identify possible quantitative and qualitative shortcomings in scientific documentation. We performed a descriptive, cross-sectional study of the references contained in 796 articles from 6 Spanish journals from 3 health disciplines (2000-2002) and 2 English-language nursing journals (2000-2001). The number of references, type of publication cited, and language of the document cited were compared in individual journals, and in journals grouped by discipline and according to language. Spanish-language nursing journals had the lowest mean number of references per article (X- = 16.20) when compared with psychology journals (X- = 31.24), medical journals (X- = 31.39) and international nursing journals (X- = 37.11). Among Spanish journals, citation of English-language publications was most frequent in medical journals (X- = 26.28) and least frequent in nursing journals (X- = 6.04). In contrast, citation of Spanish documents was most frequent in nursing journals (X- = 9.79) and least frequent in medical journals (X- = 4.43). Although scientific publication of Spanish nursing has improved, it is not comparable to publication of closely related disciplines and international nursing. The low citation of English documents clearly reveals the risk of scientific insularity.

    The aim of this study was to conduct a review of articles about tobacco or alcohol published from 1980 to 2010 in the Journal of the American Dental Association (JADA), Journal of Dental Education (JDE), and Journal of Public Health Dentistry (JPHD) in an attempt to identify trends by decade in topics relevant to oral health consequences, oral cancer linkages, and cessation counseling. NVivo qualitative analysis software was used to code abstracts using the keywords "tobacco" or "alcohol." The search identified 269 articles: tobacco=211 (78%), alcohol=58 (22%). This number represented 2.4% of the total articles published in these journals for the specified years. While the percentage of tobacco-related articles increased over this period (with highs in the 1990s of 4.1% in the JDE and 9% in the JPHD), the percentage of alcohol articles reached only 1% for JADA and 3.3% for the JPHD in the 2000s. The number of tobacco-related articles addressing oral health effects, oral cancer linkages, and cessation counseling increased in the 1990s. Although there were modest increases in the number of articles about alcohol-related oral health effects and oral cancer linkages (particularly in the JPHD in the 2000s), only two articles (in JADA in the 2000s) addressed alcohol cessation counseling. This study concluded that tobacco and alcohol have received limited, though increasing, attention in these three major journals between 1980 and 2010, with alcohol receiving less attention than tobacco. These results suggest a need for more published studies on tobacco and alcohol interventions in dental and allied dental education to prepare students to contribute to this aspect of their patients' health.

    Despite its relatively recent introduction to clinical practice, PET/CT has gained wide acceptance both in diagnostic and therapeutic applications. Scientific publication in PET/CT has also experienced significant development since its introduction. Bibliometric analyses allow an understanding of how this publication trend has developed at an aggregated level. Citation analysis is one of the most widely used bibliometric tools of scientometrics. Analysis of classics, defined as an articles with 100 or more citations, is common in the biomedical sciences as it reflects an article's influence in its professional and scientific community. Our objective was to identify the 50 most frequently cited classic articles in PET/CT in the past 10 years. The 50 most-cited PET/CT articles were identified by searching ISI's Web of Knowledge and Pubmed databases for all related publications from 2000 through 2010. Articles were evaluated for several characteristics such as author(s), institution, country of origin, publication year, type, and number of citations. An unadjusted categorical analysis was performed to compare all articles published in the search period. The search yielded a cumulative total of 22,554 entries for the publication period, of which 15,943 were original research articles. The 50 most-cited articles were identified from the latter sum and selected out of 73 classics. The number of citations for the top 50 classics ranged from 114 to 700. PET/CT classics appeared in three general and 12 core journals. The majority of the classics were in oncologic applications of PET/CT (62%). Articles related to diagnostic topics were 6%. The rest were focused on physics and instrumentation 24% and other basic sciences 16%. Despite its relatively short history PET/CT accumulated 73 classic articles in a decade. Such information is of importance to researchers and those who wish to study the scientific development in the field. © 2012 American Association of Physicists in

    Physicians and researchers in the field of family medicine often need to find relevant articles in online medical databases for a variety of reasons. Because a search filter may help improve the efficiency and quality of such searches, we aimed to develop and validate search filters to identify research studies of relevance to family medicine. Using a new and objective method for search filter development, we developed and validated 2 search filters for family medicine. The sensitive filter had a sensitivity of 96.8% and a specificity of 74.9%. The specific filter had a specificity of 97.4% and a sensitivity of 90.3%. Our new filters should aid literature searches in the family medicine field. The sensitive filter may help researchers conducting systematic reviews, whereas the specific filter may help family physicians find answers to clinical questions at the point of care when time is limited.

    A method of removing substantially all of the volatile component in a green, volatile-containing ceramic article is disclosed. The method comprises freezing the ceramic article; and then subjecting the frozen article to a vacuum for a sufficient time to freeze-dry the article. Frequently, the article is heated while being freeze-dried. Use of this method efficiently reduces the propensity for any warpage of the article. The article is often formed from a ceramic slurry in a gel-casting process. A method for fabricating a ceramic core used in investment casting is also described.

  17. Semi-Supervised Learning to Identify UMLS Semantic Relations.

    2014-01-01

    The UMLS Semantic Network is constructed by experts and requires periodic expert review to update. We propose and implement a semi-supervised approach for automatically identifying UMLS semantic relations from narrative text in PubMed. Our method analyzes biomedical narrative text to collect semantic entity pairs, and extracts multiple semantic, syntactic and orthographic features for the collected pairs. We experiment with seeded k-means clustering with various distance metrics. We create and annotate a ground truth corpus according to the top two levels of the UMLS semantic relation hierarchy. We evaluate our system on this corpus and characterize the learning curves of different clustering configuration. Using KL divergence consistently performs the best on the held-out test data. With full seeding, we obtain macro-averaged F-measures above 70% for clustering the top level UMLS relations (2-way), and above 50% for clustering the second level relations (7-way).

    ABSTRACT Objective: To investigate whether Brazilian articles on cancer are published in journals with an impact factor and/or repercussion (measured by the number of citations) inferior to those that come from foreign organizations. Methods: A search was carried out in PubMed for the MeSH term “neoplasm” with the limits clinical trial, affiliation of the Brazilian author(s), and interval from July 1st, 2009 to June 30, 2010. Selected for matching were non-Brazilian related articles published from three months prior to three months after the date of publication of the Brazilian study. The numbers of citations were obtained from two databases, as well as the impact factor for the journals in which the articles were published. Results: Fortythree national and 876 related international articles were identified. The Brazilian publications had a mean impact factor of 3.000 versus 3.430 of the international ones (p=0.041). There was no statistically significant difference as to the number of citations between the two groups. The affiliation of the first author with a Brazilian or foreign organization did not significantly influence the number of citations or the impact factor. Conclusion: Brazilian articles are significantly less accepted in journals with higher impact factors, although it does not compromise its repercussion on the scientific community. PMID:23579739

    To identify and characterize the most frequently cited articles that have been published on aortic dissection. A list of the 100 most frequently cited publications (T100) about aortic dissection was generated by performing a searching of the Science Citation Index--Expanded using "aortic dissection" as the search term. Basic information about the articles was recorded, including number of citations, journal title, journal impact factor, time since publication, first author's country, topic/subspecialty of the research, and publication type. We finally included 180 articles on aortic dissection, from which we identified the 100 most frequently cited articles (T100). The most frequently cited article received 1079 citations, while the least frequently cited article received 68 (mean140.5 citations per article). The T100 originated from 19 countries, with more than half of them originating from the USA (n = 97). The T100 articles were published from 1955 to 2013, with 79% published during the period 1990-2009. In addition, there were 40 different journals with Circulation having the most citations (n = 38). Regarding the article type, there were 21 basic and 140 clinical research articles, one meta-analysis, and 18 review articles. Reviews had the highest mean number of citations (mean 235.5 citations per article). Our study provides a historical perspective on the progress of dissection research, and helps to identify the quality of the work, the discoveries made, and the trends steering the studies.

    Microsurgery has developed significantly since the inception of the first surgical microscope. There have been few attempts to describe "classic" microsurgery articles. In this study citation analysis was done to identify the most highly cited clinical and basic science articles published in five peer-reviewed plastic surgery journals. Thomson/Reuters web of knowledge was used to identify the most highly cited microsurgery articles from five journals: Plastic and Reconstructive Surgery, Annals of Plastic Surgery, Journal of Plastic, Reconstructive & Aesthetic Surgery, Journal of Reconstructive Microsurgery, and Microsurgery. Articles were identified and sorted based on the number of citations and citations per year. The 50 most cited clinical and basic science articles were identified. For clinical articles, number of total citations ranged from 120 to 691 (mean, 212.38) and citations per year ranged from 30.92 to 3.05 (mean, 9.33). The most common defect site was the head and neck (n = 15, 30%), and flaps were perforator and muscle/musculocutaneous flaps (n = 10 each, 20%, respectively). For basic science articles, number of citations ranged from 71 to 332 (mean, 130.82) and citations per year ranged from 2.20 to 11.07 (mean, 5.27). There were 27 animal, 21 cadaveric, and 2 combined studies. The most highly cited microsurgery articles are a direct reflection of the educational and clinical trends. Awareness of the most frequently cited articles may serve as a basis for core knowledge in the education of plastic surgery trainees. III.

    AIMS Cannabis is the most prevalent illicit drug used worldwide and can be responsible for serious health defects in users. However, the risk related to cannabis consumption is not well established. The present study aimed to assess cannabis-related adverse events leading to hospitalization, and to estimate the corresponding annual risk for consumers. METHODS Participants were patients admitted to the public hospitals in the Toulouse area (France) between January 2004 and December 2007 in relation to the use of cannabis. Reasons for admission and other occurring events were identified through hospital discharge summaries. We described all observed adverse events (AEs) and estimated their regional incidence on the basis of cannabis consumption data. RESULTS We included 200 patients, and identified a total of 619 adverse events (AEs), one of which was lethal. Psychiatric disorders involved 57.7% of patients and accounted for 18.2% of AEs. Most frequent outcomes were central and peripheral nervous system disorders (15.8% of AEs), acute intoxication (12.1%), respiratory system disorders (11.1%) and cardiovascular disorders (9.5%). We estimated that in 2007 the incidence of cannabis-related AEs in the Midi-Pyrenees region ranged from 1.2 per 1000 regular cannabis users (95% confidence interval (CI) 0.7, 1.6) to 3.2 (95% CI 2.5, 3.9). CONCLUSIONS Cannabis use is associated with complications, considered to be serious since they lead to hospitalization. Beyond the well-known and widely investigated psychiatric events, serious cerebro and cardiovascular complications have been identified. These findings contribute to improve the knowledge of cannabis-related adverse events. PMID:21204913

    Physicians and researchers in the field of family medicine often need to find relevant articles in online medical databases for a variety of reasons. Because a search filter may help improve the efficiency and quality of such searches, we aimed to develop and validate search filters to identify research studies of relevance to family medicine. Using a new and objective method for search filter development, we developed and validated 2 search filters for family medicine. The sensitive filter had a sensitivity of 96.8% and a specificity of 74.9%. The specific filter had a specificity of 97.4% and a sensitivity of 90.3%. Our new filters should aid literature searches in the family medicine field. The sensitive filter may help researchers conducting systematic reviews, whereas the specific filter may help family physicians find answers to clinical questions at the point of care when time is limited. © 2015 Annals of Family Medicine, Inc.

    2017-01-18

    The widespread adoption of health information technology (HIT) has led to new patient safety hazards that are often difficult to identify. Patient safety event reports, which are self-reported descriptions of safety hazards, provide one view of potential HIT-related safety events. However, identifying HIT-related reports can be challenging as they are often categorized under other more predominate clinical categories. This challenge of identifying HIT-related reports is exacerbated by the increasing number and complexity of reports which pose challenges to human annotators that must manually review reports. In this paper, we apply active learning techniques to support classification of patient safety event reports as HIT-related. We evaluated different strategies and demonstrated a 30% increase in average precision of a confirmatory sampling strategy over a baseline no active learning approach after 10 learning iterations.

    To retrieve, summarize and analyze journals and articles related to acupuncture published in SCI periodicals in 2005, so as to understand the international dynamics about acupuncture researches. The articles about treatment and mechanisms of acupuncture published in SCI periodicals in 2005 were found out and searched for by acupuncture information retrieval online and databank. Most of the 72 SCI periodicals retrieved are from the west, with 147 articles of acupuncture published, and Lancet has the highest impact factors of 23. 407. The kinds of the journals and articles publishing acupuncture researches are increasing, with varied types, rich and varied contents, and increasing the design level. However, the results of the studies are vastly different due to differences of experimental methods, objects and acupuncture manipulations. Therefore, standardization of acupuncture studies is extremely urgent.

    1974-01-01

    A survey was conducted of six aerospace companies and two NASA agencies to determine how prototype structural test articles are used in flight operations. The prototype structures are airframes and similar devices which are used for testing and generally are not flown. The survey indicated the following: (1) prototype test articles are not being discarded after development testing is complete, but are used for other purposes, (2) only two cases of prototypes being refurbished and flown were identified, (3) protective devices and inspection techniques are available to prevent or minimize test article damage, (4) substitute programs from design verification are availabel in lieu of using prototype structural articles, and (5) there is a trend away from dedicated test articles. Four options based on these study results were identified to reduce test and hardware costs without compromising reliability of the flight program.

    Day labor is largely comprised of young Latino immigrant men, many of who are undocumented, and thus vulnerable to a myriad of workers' rights abuses. The difficult work and life conditions of this marginalized population may place them at heightened risk for mental health problems and substance use and abuse. However, factors related to Latino day laborers' well-being and substance misuse are largely unknown. This article utilizes ethnographic and focus group methodology to elucidate participant identified factors associated to well-being and substance use and abuse. This study has implications for informing public health and social service programming as it provides thick description regarding the context and circumstances associated to increased vulnerability to substance abuse and lack of well-being among this hard-to-reach population of Latino immigrants.

    Identifying fall-related injuries and costs using healthcare claims data is cost-effective and easier to implement than using medical records or patient self-report to track falls. We developed a comprehensive four-step algorithm for identifying episodes of care for fall-related injuries and associated costs, using fee-for-service Medicare and Medicare Advantage health plan claims data for 2,011 patients from 5 medical groups between 2005 and 2009. First, as a preparatory step, we identified care received in acute inpatient and skilled nursing facility settings, in addition to emergency department visits. Second, based on diagnosis and procedure codes, we identified all fall-related claim records. Third, with these records, we identified six types of encounters for fall-related injuries, with different levels of injury and care. In the final step, we used these encounters to identify episodes of care for fall-related injuries. To illustrate the algorithm, we present a representative example of a fall episode and examine descriptive statistics of injuries and costs for such episodes. Altogether, we found that the results support the use of our algorithm for identifying episodes of care for fall-related injuries. When we decomposed an episode, we found that the details present a realistic and coherent story of fall-related injuries and healthcare services. Variation of episode characteristics across medical groups supported the use of a complex algorithm approach, and descriptive statistics on the proportion, duration, and cost of episodes by healthcare services and injuries verified that our results are consistent with other studies. This algorithm can be used to identify and analyze various types of fall-related outcomes including episodes of care, injuries, and associated costs. Furthermore, the algorithm can be applied and adopted in other fall-related studies with relative ease.

  17. Overview Article: Identifying transcriptional cis-regulatory modules in animal genomes

    2014-01-01

    Gene expression is regulated through the activity of transcription factors and chromatin modifying proteins acting on specific DNA sequences, referred to as cis-regulatory elements. These include promoters, located at the transcription initiation sites of genes, and a variety of distal cis-regulatory modules (CRMs), the most common of which are transcriptional enhancers. Because regulated gene expression is fundamental to cell differentiation and acquisition of new cell fates, identifying, characterizing, and understanding the mechanisms of action of CRMs is critical for understanding development. CRM discovery has historically been challenging, as CRMs can be located far from the genes they regulate, have few readily-identifiable sequence characteristics, and for many years were not amenable to high-throughput discovery methods. However, the recent availability of complete genome sequences and the development of next-generation sequencing methods has led to an explosion of both computational and empirical methods for CRM discovery in model and non-model organisms alike. Experimentally, CRMs can be identified through chromatin immunoprecipitation directed against transcription factors or histone post-translational modifications, identification of nucleosome-depleted “open” chromatin regions, or sequencing-based high-throughput functional screening. Computational methods include comparative genomics, clustering of known or predicted transcription factor binding sites, and supervised machine-learning approaches trained on known CRMs. All of these methods have proven effective for CRM discovery, but each has its own considerations and limitations, and each is subject to a greater or lesser number of false-positive identifications. Experimental confirmation of predictions is essential, although shortcomings in current methods suggest that additional means of validation need to be developed. PMID:25704908

    Citation analysis was performed in order to identify the top 50 most cited articles pertaining to the field of primary spinal tumors. This collection of articles highlights important trends in the neurosurgical literature. We searched the Thomson Reuters Web of Knowledge in order to identify articles pertaining to primary tumors of the spine. Impertinent articles were removed. The top 50 most cited articles were identified. Thereafter, article characteristics were determined including article type, article topic, level of evidence, and citation rate. The selected articles were published between 1951 and 2008. The most productive year was 1997 with 6 publications. The top 50 articles were published in twenty-two different journals, most commonly in Neurosurgery (12), Journal of Neurosurgery (8), and Spine (6). The most frequently cited article was by Tomita et al. written in 1997 which described total en bloc spondylectomy as a novel surgical technique in management of primary tumors of the vertebral column. We identified the 50 most-cited articles in the field of primary spinal tumors. This collection of articles serves as a reference for recognizing impactful studies in the field. Copyright © 2017.

    Much research has been done in Northeast Asia to show the efficacy of traditional medicine. While MEDLINE contains many biomedical articles including those on traditional medicine, it does not categorize those articles by specific research area. The aim of this study was to provide a method that searches for articles only on traditional medicine in Northeast Asia, including traditional Chinese medicine, from among the articles in MEDLINE. This research established an SVM-based classifier model to identify articles on traditional medicine. The TAK + HM classifier, trained with the features of title, abstract, keywords, herbal data, and MeSH, has a precision of 0.954 and a recall of 0.902. In particular, the feature of herbal data significantly increased the performance of the classifier. By using the TAK + HM classifier, a total of about 108,000 articles were discriminated as articles on traditional medicine from among all articles in MEDLINE. We also built a web server called DisArticle ( http://informatics.kiom.re.kr/disarticle ), in which users can search for the articles and obtain statistical data. Because much evidence-based research on traditional medicine has been published in recent years, it has become necessary to search for articles on traditional medicine exclusively in literature databases. DisArticle can help users to search for and analyze the research trends in traditional medicine.

    Acoustic neuroma is the most common extra-axial primary cerebellopontine angle tumor in adults. A plethora of studies have been published on acoustic neuroma, but none of the previous works have highlighted the most influential articles. Our objective was to perform a bibliometric analysis of the 50 most-cited articles on acoustic neuroma. We performed a title-specific search on the Scopus database using the following search terms: "acoustic neuroma," "vestibular schwannoma," and "cerebellopontine angle." We recorded the 50 most-cited articles and reviewed them. The 50 most-cited articles had an average of 175 citations per article. All articles were published between 1980 and 2006, with 1997 the most prolific year, when 7 articles were published. The journals Neurosurgery and Laryngoscope published 10 and 8 of these articles, respectively. The most common study categories were nonsurgical management (17/50) and surgical management (13/50). Studies were predominantly published by otolaryngologists (22/50) and neurosurgeons (14/50). Douglas Kondziolka was the author with the highest number of contributions, with 7 publications. The majority of the articles were produced in the United States (64%). Identifying articles on acoustic neuroma with the most impact provides an important overview of the historical development of treatment methods and publication trends related to this condition. A finalized, comprehensive list of the most important works represents an excellent tool that can serve as a guide for evidence-based clinical practice. Copyright © 2017 Elsevier Inc.

    In the past two decades enormously scientific researches on posttraumatic stress disorder (PTSD) have been undertaken and many related meta-analyses have been published. Citation analysis was used to get comprehensive perspectives of meta-analysis articles (MA articles) on PTSD for the purpose of facilitating the researchers, physicians and policy-makers to understand the PTSD. MA articles on PTSD in any languages from January 1980 to March 2009 were included if they presented meta-analytical methods and received at least one citation recorded in the Web of Science (WoS). Whereas studies, in which any effect sizes of PTSD were not distinguished from other psychological disorders, were excluded. Citations to and by identified MA articles were documented basing on records in WoS. Citation analysis was used to examine distribution patterns of characteristics and citation impact of MA articles on PTSD. Canonical analysis was used to explore the relationship between the characteristics of MA articles and citation impact. Thirty-four MA articles published during 1998 and 2008 were identified and revealed multiple study topics on PTSD: 10 (29.4%) were about epidemiology, 13 (38.2%) about treatment or intervention, 6 (17.6%) about pathophysiology or neurophysiology or neuroendocrine, 3 (8.8%) about childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most frequently with 456 and 145 counts were published in Journal of Consulting and Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003), respectively. Mean cited count was 7.48 ± 10.56 and mean age (year 2009 minus article publication year) was (4.24 ± 2.91) years. They had been cited approximately by 67 disciplines and by authors from 42 countries or territories. Characteristics of meta-analysis highly correlated with citation impact and reflected by canonical correlation of 0.899 (P < 0.000 01). The age of MA articles predicted their citation impact.

    Twitter is an extremely high volume platform for user generated contributions regarding any topic. The wealth of content created at real-time in massive quantities calls for automated approaches to identify the topics of the contributions. Such topics can be utilized in numerous ways, such as public opinion mining, marketing, entertainment, and disaster management. Towards this end, approaches to relate single or partial posts to knowledge base items have been proposed. However, in microblogging systems like Twitter, topics emerge from the culmination of a large number of contributions. Therefore, identifying topics based on collections of posts, where individual posts contribute to some aspect of the greater topic is necessary. Models, such as Latent Dirichlet Allocation (LDA), propose algorithms for relating collections of posts to sets of keywords that represent underlying topics. In these approaches, figuring out what the specific topic(s) the keyword sets represent remains as a separate task. Another issue in topic detection is the scope, which is often limited to specific domain, such as health. This work proposes an approach for identifying domain-independent specific topics related to sets of posts. In this approach, individual posts are processed and then aggregated to identify key tokens, which are then mapped to specific topics. Wikipedia article titles are selected to represent topics, since they are up to date, user-generated, sophisticated articles that span topics of human interest. This paper describes the proposed approach, a prototype implementation, and a case study based on data gathered during the heavily contributed periods corresponding to the four US election debates in 2012. The manually evaluated results (0.96 precision) and other observations from the study are discussed in detail.

    Publication retraction is a mechanism to preserve the scientific literature against publications that contain seriously flawed or erroneous data, redundant publication, plagiarism, unethical research, and other features that compromise the integrity of science. An increase in the occurrence of retractions in recent years has been reported. Nevertheless, there is scarce information on this topic concerning publications in dentistry and related specialties. Thus, this study aimed to investigate retracted papers published in dental journals. Data collection included an exploratory search in PubMed and a specific search in SCImago Journal Rank indexed journals, complemented by the cases reported on the Retraction Watch website and in PubMed. All 167 dental journals included in SCImago were searched for identification of retracted articles up to March 2016. The selected retracted articles and their corresponding retraction notices were recorded and assessed for classification according to the reason for retraction and other additional information. Forty of the 167 journals scrutinised at SCImago (23.9%) had at least one retracted article, and four additional journals were identified from the Retraction Watch website. A total of 72 retracted found were retracted for the reasons: redundant publication (20.8%), plagiarism (18.1%), misconduct (13.8%), overlap (13.6%) and honest error (9.7%). Higher number of retractions were reported in those journals with cites/doc <2.0-n = 49 (74.2%). The types of studies were mainly laboratory studies (34.7%), case reports (22.2%) and review articles (13.9%). The approach to ethical problems in papers published in dental scientific journals is still incipient; retractions were mostly due to the authors' malpractice and were more frequently related to journals with less impact.

    Citation classics have been published in many fields of medicine; however, none have focused on interventional cardiology. The goal of this study was to identify the top 100 articles in the field of interventional cardiology and highlight their important trends and characteristics. The Scopus database was used by 2 independent reviewers to extract the top 100 articles using a variety of keywords. We found articles published between 1953 and 2012. Majority (n = 78) of the top 100 articles were published between 1996 and 2010, and the United States was affiliated with the highest number of articles in our list (n = 68). Over half (n = 54) the articles were funded. Private funding was correlated with higher citations (p = 0.036). A third (n = 33) of the papers had authors with conflicts of interest; however, conflict of interest had no effect on citations (p = 0.837). Majority (n = 57) of the articles studied coronary angioplasty and stenting; followed by coronary angiography (n = 14). Women were underrepresented, with only 11 female first authors in the top 100 papers, and only 1 female in the list of top authors who had 5 or more publications. In conclusion, the following features define the typical highly cited article in interventional cardiology-a clinical trial conducted in the United States, which studies angioplasty, and has been published relatively recently in a high-impact journal by a male first author.

    Background Little is known about differences in alcohol use and alcohol-related problems between transgender- and nontransgender-identified populations. Using data from a large-scale health survey, we compare the drinking patterns and prevalence of alcohol-related problems of transgender-identified individuals to nontransgender-identified males and females. For transgender-identified people, we examine how various forms of victimization relate to heavy episodic drinking (HED). Methods Cross-sectional surveys were completed by 75,192 students aged 18–29 years attending 120 post-secondary educational institutions in the United States from 2011–2013. Self-reported measures included alcohol use, alcohol-related problems, victimization, and sociodemographics, including 3 gender-identity groups: transgender-identified individuals; nontransgender-identified males; and nontransgender-identified females. Results Compared to transgender-identified individuals, nontransgender-identified males were more likely to report HED in the past 2 weeks (relative risk=1.42; p=0.006); however, nontransgender-identified males and females reported HED on fewer days than transgender-identified people (incidence-rate ratios [IRRs] ranged from 0.28–0.43; p-values<0.001). Compared to transgender-identified people, nontransgender-identified males and females had lower odds of past-year alcohol-related sexual assault and suicidal ideation (odds ratios ranged from 0.24–0.45; p-values<0.05). Among transgender-identified people, individuals who were sexually assaulted (IRR=3.21, p=0.011) or verbally threatened (IRR=2.42, p=0.021) in the past year had greater HED days than those who did not experience those forms of victimization. Conclusions Compared to transgender-identified people, nontransgender-identified males and females: have fewer HED occasions (despite nontransgender-identified males having greater prevalence of HED); and are at lower risk for alcohol-related sexual assaults and

    Our purpose was to identify the top 100 cited articles, which focused on CT colonography (CTC). This list could then be analysed to establish trends in CTC research while also identifying common characteristics of highly cited works. Web of Science search was used to create a database of scientific journals using our search terms. A total of 10,597 articles were returned from this search. Articles were included if they focused on diagnostic imaging, imaging technique, cost-effectiveness analysis, clinical use, patient preference or trends in CTC. Articles were ranked by citation count and screened by two attending radiologists. The following information was collected from each article: database citations, citations per year, year published, journal, authors, department affiliation, study type and design, statistical analysis, sample size, modality and topic. Citations for the top 100 articles ranged from 73 to 1179, and citations per year ranged from 4.5 to 84.21. Articles were published across 22 journals, most commonly Radiology (n = 37) and American Journal of Roentgenology (n = 19). Authors contributed from 1 to 20 articles. 19% of first authors were affiliated with a department other than radiology. Of the 100 articles, the most common topics were imaging technique (n = 40), diagnostic utility of imaging (n = 28) and clinical uses (n = 18). Our study provides intellectual milestones in CTC research, reflecting on the characteristics and quality of published literature. This work also provides the most influential references related to CTC and serves as a guide to the features of a citable paper in this field.

    To characterize disclosures of conflicts of interest in review articles in psychiatry, we identified 285 reviews from 10 high-impact journals in psychiatry and 2 in general medicine. Disclosures were reliably coded as biotechnology/pharmaceutical/other material interests, nonprofit/government, communication companies, or other. The authors in both types of journals frequently reported industry ties. However, the reviews in the psychiatric journals were significantly less likely to include industry-related disclosures (32% of the reviews; 18% of the authors) compared with the general medical journals (64% of the articles; 40% of the authors). The most common types of industry-related disclosures were for consulting, research support, and speaking fees. Disclosures seemed to be of limited utility in helping readers assess possible biases because the nature and the extent of the relationships being disclosed were often unclear. Efforts to screen out authors with significant financial relationships pertaining to the topic under review may be more effective than are disclosures in protecting the integrity of the medical literature.

    OBJECTIVE The authors' objective was to identify the 100 most-cited research articles in the field of spinal oncology. METHODS The Thomson Reuters Web of Science service was queried for the years 1864-2015 without language restrictions. Articles were sorted in descending order of the number of times they were cited by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. Levels of evidence were assigned on the basis of the North American Spine Society criteria. RESULTS The authors identified the 100 most-cited articles in spinal oncology, which collectively had been cited 20,771 times at the time of this writing. The oldest article on this top 100 list had been published in 1931, and the most recent in 2008; the most prolific decade was the 1990s, with 34 articles on this list having been published during that period. There were 4 studies with Level I evidence, 3 with Level II evidence, 9 with Level III evidence, 70 with Level IV evidence, and 2 with Level V evidence; levels of evidence were not assigned to 12 studies because they were not on therapeutic, prognostic, or diagnostic topics. Thirty-one unique journals contributed to the 100 articles, with the Journal of Neurosurgery contributing most of the articles (n = 25). The specialties covered included neurosurgery, orthopedic surgery, neurology, radiation oncology, and pathology. Sixty-seven articles reported clinical outcomes. The most common country of article origin was the United States (n = 62), followed by Canada (n = 8) and France (n = 7). The most common topics were spinal metastases (n = 35), intramedullary tumors (n = 18), chordoma (n = 17), intradural tumors (n = 7), vertebroplasty/kyphoplasty (n = 7), primary bone tumors (n = 6), and others (n = 10). One researcher had authored 6 studies on the top 100 list, and 7 authors had 3 studies each on this list. CONCLUSIONS This study identified the 100 most-cited research articles in the area of

    Background: Comprehensive systems for surveilling prescription opioid–related harms provide clear evidence that deaths from prescription opioids have increased dramatically in the United States. However, these harms are not systematically monitored in Canada. In light of a growing public health crisis, accessible, nationwide data sources to examine prescription opioid–related harms in Canada are needed. We sought to examine the performance of 5 algorithms to identify prescription opioid–related deaths from vital statistics data against data abstracted from the Office of the Chief Coroner of Ontario as a gold standard. Methods: We identified all prescription opioid–related deaths from Ontario coroners’ data that occurred between Jan. 31, 2003, and Dec. 31, 2010. We then used 5 different algorithms to identify prescription opioid–related deaths from vital statistics death data in 2010. We selected the algorithm with the highest sensitivity and a positive predictive value of more than 80% as the optimal algorithm for identifying prescription opioid–related deaths. Results: Four of the 5 algorithms had positive predictive values of more than 80%. The algorithm with the highest sensitivity (75%) in 2010 improved slightly in its predictive performance from 2003 to 2010. Interpretation: In the absence of specific systems for monitoring prescription opioid–related deaths in Canada, readily available national vital statistics data can be used to study prescription opioid–related mortality with considerable accuracy. Despite some limitations, these data may facilitate the implementation of national surveillance and monitoring strategies. PMID:26622006

    A bibliometric uses the citation count of an article to determine its impact on the clinical world. There is a paucity of literature concerning top article citations on spontaneous intracerebral hemorrhage (ICH). The main objective of this investigation was to bridge this gap and to provide understanding of the trends on the most influential articles written on this subject. The Scopus Library database was searched to determine the citations of all articles published on spontaneous ICH. Articles that focused on other forms of ICH, such as trauma-related hemorrhages, subarachnoid hemorrhages, or hemorrhages caused by anticoagulation, vascular malformations, or cavernomas, were excluded from our list. The articles were divided into 2 groups: "specific" articles, which focused specifically on spontaneous ICH, and "generalized" articles, which were about ICH in general, including spontaneous as well as other forms of ICH. We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. J. Broderick was the author with most publications in the list (n = 21). The largest subset of spontaneous ICH articles was published in the 5-year periods from 1996 to 2000 and 2001 to 2005 (n = 27 each). The United States had the highest number of articles (n = 49). The journal with the highest number of top 100 cited articles was Stroke, with 39, followed by Neurology with 16. Our study identifies the trends related to spontaneous ICH by analyzing the citation frequency of the most-cited articles in the field. Copyright © 2017 Elsevier Inc. All rights reserved.

    Craniovertebral junction is a complex anatomical location posing unique challenges to the surgical management of its pathologies. We aimed to identify the fifty most-cited articles that are dedicated to this field. A keyword search using the Thomson Reuters Web of Knowledge was conducted to identify articles relevant to the field of craniovertebral junction surgery. The articles were reviewed based on title, abstract, and methods, if necessary, and then ranked based on the total number of citations to identify the fifty most-cited articles. Characteristics of the articles were determined and analyzed. The earliest top-cited article was published in 1948. When stratified by decade, 1990s was the most productive with 16 articles. The most-cited article was by Anderson and Dalonzo on a classification of odontoid fractures. By citation rate, the most-cited article was by Herms and Melcher who described Goel's technique of atlantoaxial fixation using C1 lateral mass screws and C2 pedicle screws with rod fixation. Atlantoaxial fixation was the most common topic. The United States, Barrow Neurological Institute, and VH Sonntag were the most represented country, institute, and author, respectively. The significant majority of articles were designed as case series providing level IV evidence. Using citation analysis, we have provided a list of the most-cited articles representing important contributions of various authors from many institutions across the world to the field of craniovertebral junction surgery.

    OBJECTIVE Despite the growing neurosurgical literature, a subset of pioneering studies have significantly impacted the field of metastatic spine disease. The purpose of this study was to identify and analyze the 100 most frequently cited articles in the field. METHODS A keyword search using the Thomson Reuters Web of Science was conducted to identify articles relevant to the field of metastatic spine disease. The results were filtered based on title and abstract analysis to identify the 100 most cited articles. Statistical analysis was used to characterize journal frequency, past and current citations, citation distribution over time, and author frequency. RESULTS The total number of citations for the final 100 articles ranged from 74 to 1169. Articles selected for the final list were published between 1940 and 2009. The years in which the greatest numbers of top-100 studies were published were 1990 and 2005, and the greatest number of citations occurred in 2012. The majority of articles were published in the journals Spine (15), Cancer (11), and the Journal of Neurosurgery (9). Forty-four individuals were listed as authors on 2 articles, 9 were listed as authors on 3 articles, and 2 were listed as authors on 4 articles in the top 100 list. The most cited article was the work by Batson (1169 citations) that was published in 1940 and described the role of the vertebral veins in the spread of metastases. The second most cited article was Patchell's 2005 study (594 citations) discussing decompressive resection of spinal cord metastases. The third most cited article was the 1978 study by Gilbert that evaluated treatment of epidural spinal cord compression due to metastatic tumor (560 citations). CONCLUSIONS The field of metastatic spine disease has witnessed numerous milestones and so it is increasingly important to recognize studies that have influenced the field. In this bibliographic study the authors identified and analyzed the most influential articles in the

    This study determined the impact and influence of published articles on the field of occupational stress. A transdisciplinary approach was used to identify the 50 work-related stress articles with the most lifetime citations and the 50 work-related stress articles with the highest annual citation rates. Studies were categorized based on their primary focus: (a) etiology, (b) predictor of outcome for which occupational stress is the outcome or predictor of outcome for which occupational stress is an independent variable, (c) management/intervention, (d) theory/model/framework, or (e) methodologies. The majority of studies with the highest number of lifetime citations as well as the highest annual citation rates used stress as a predictor or outcome of another factor. The proportion of studies that were categorized by etiology, intervention/management, theory/model/framework, or methodologies was relatively low for both lifetime and annual citations.

    A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI). We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. A total of 73 articles were included in this review, with 27 of the 50 papers with the highest annual citation rates common to the cohort of 50 articles with the most lifetime citations. All papers were categorized by their primary topic or focus, namely: predictor of outcome, pathology/natural history, treatment, guidelines and consensus statements, epidemiology, assessment measures, or experimental model of TBI. The mean year of publication of the articles with the most lifetime citations and highest annual citation rates was 1990 ± 14.9 years and 2003 ± 6.7 years, respectively. The 50 articles with the most lifetime citations typically studied predictors of outcome (34.0%, 17/50) and were specific to severe TBI (38.0%, 19/50). In contrast, the most common subject of papers with the highest annual citation rates was treatment of brain injury (22.0%, 11/50), and these papers most frequently investigated mild TBI (36.0%, 18/50). These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for brain injury. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of

    With limited health care resources, bibliometric studies can help guide researchers and research funding agencies towards areas where reallocation or increase in research activity is warranted. Bibliometric analyses have been published in many specialties and sub-specialties but our literature search did not reveal a bibliometric analysis on Cardiovascular Magnetic Resonance (CMR). The main objective of the study was to identify the trends of the top 100 cited articles on CMR research. Web of Science (WOS) search was used to create a database of all English language scientific journals. This search was then cross-referenced with a similar search term query of Scopus® to identify articles that may have been missed on the initial search. Articles were ranked by citation count and screened by two independent reviewers. Citations for the top 100 articles ranged from 178 to 1925 with a median of 319.5. Only 17 articles were cited more than 500 times, and the vast majority (n = 72) were cited between 200-499 times. More than half of the articles (n = 52) were from the United States of America, and more than one quarter (n = 21) from the United Kingdom. More than four fifth (n = 86) of the articles were published between the time period 2000-2014 with only 1 article published before 1990. Circulation and Journal of the American College of Cardiology made up more than half (n = 62) of the list. We found 10 authors who had greater than 5 publications in the list. Our study provides an insight on the characteristics and quality of the most highly cited CMR literature, and a list of the most influential references related to CMR.

    Citation analysis reflects the scientific recognition and influential performance of an article in the scientific community. The objective of this study was to identify and characterize the 100 most cited articles on oral submucous fibrosis (OSF). A list of 100 most cited articles related to OSF was retrieved from the Science Citation Index-Expanded tool of Scopus database in May 2018.The articles were further reviewed, and basic information was recorded including the number of citations, citation density, journals, with its impact factor, category and quartile, publication year, authors, institution and country of origin, article type and level of evidence. Descriptive statistics were used to summarize the results. The most frequently cited article received 780 citations, while the least frequently cited article received 49 (mean107.5 citations per article). There were 38 different journals with Journal of Oral Pathology and Medicine having the most citations (n = 22).The 100 most cited articles were published from 1966 to 2013, with 81% published after 1990.Thirteen authors listed 5 or more articles in the top 100 list and India was found to be the most prolific country with 38 articles. In terms of article type, there were 72 research articles and 28 review articles. This first citation analysis of the 100 most cited articles render a historical perspective on the progress of research in the field of OSF and enables the comprehensive identification and recognition of the most important and relevant research topics concerned.

    Over the last decade, an increasing number of integrative studies on cancer-related genes have been published. Integrative analyses aim to overcome the limitation of a single data type, and provide a more complete view of carcinogenesis. The vast majority of these studies used sample-matched data of gene expression and copy number to investigate the impact of copy number alteration on gene expression, and to predict and prioritize candidate oncogenes and tumor suppressor genes. However, correlations between genes were neglected in these studies. Our work aimed to evaluate the co-alteration of copy number, methylation and expression, allowing us to identify cancer-related genes and essential functional modules in cancer. We built the Integrated Co-alteration network (ICan) based on multi-omics data, and analyzed the network to uncover cancer-related genes. After comparison with random networks, we identified 155 ovarian cancer-related genes, including well-known (TP53, BRCA1, RB1 and PTEN) and also novel cancer-related genes, such as PDPN and EphA2. We compared the results with a conventional method: CNAmet, and obtained a significantly better area under the curve value (ICan: 0.8179, CNAmet: 0.5183). In this paper, we describe a framework to find cancer-related genes based on an Integrated Co-alteration network. Our results proved that ICan could precisely identify candidate cancer genes and provide increased mechanistic understanding of carcinogenesis. This work suggested a new research direction for biological network analyses involving multi-omics data.

    Identifying the set of intrinsically conserved genes, or the genomic core, among related genomes is crucial for understanding prokaryotic genomes where horizontal gene transfers are common. Although core genome identification appears to be obvious among very closely related genomes, it becomes more difficult when more distantly related genomes are compared. Here, we consider the core structure as a set of sufficiently long segments in which gene orders are conserved so that they are likely to have been inherited mainly through vertical transfer, and developed a method for identifying the core structure by finding the order of pre-identified orthologous groups (OGs) that maximally retains the conserved gene orders. The method was applied to genome comparisons of two well-characterized families, Bacillaceae and Enterobacteriaceae, and identified their core structures comprising 1438 and 2125 OGs, respectively. The core sets contained most of the essential genes and their related genes, which were primarily included in the intersection of the two core sets comprising around 700 OGs. The definition of the genomic core based on gene order conservation was demonstrated to be more robust than the simpler approach based only on gene conservation. We also investigated the core structures in terms of G+C content homogeneity and phylogenetic congruence, and found that the core genes primarily exhibited the expected characteristic, i.e., being indigenous and sharing the same history, more than the non-core genes. The results demonstrate that our strategy of genome alignment based on gene order conservation can provide an effective approach to identify the genomic core among moderately related microbial genomes.

    To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the

  5. Determining the relative importance of figures in journal articles to find representative images

    When physicians are searching for articles in the medical literature, images of the articles can help determining relevance of the article content for a specific information need. The visual image representation can be an advantage in effectiveness (quality of found articles) and also in efficiency (speed of determining relevance or irrelevance) as many articles can likely be excluded much quicker by looking at a few representative images. In domains such as medical information retrieval, allowing to determine relevance quickly and accurately is an important criterion. This becomes even more important when small interfaces are used as it is frequently the case on mobile phones and tablets to access scientific data whenever information needs arise. In scientific articles many figures are used and particularly in the biomedical literature only a subset may be relevant for determining the relevance of a specific article to an information need. In many cases clinical images can be seen as more important for visual appearance than graphs or histograms that require looking at the context for interpretation. To get a clearer idea of image relevance in articles, a user test with a physician was performed who classified images of biomedical research articles into categories of importance that can subsequently be used to evaluate algorithms that automatically select images as representative examples. The manual sorting of images of 50 journal articles of BioMedCentral with each containing more than 8 figures by importance also allows to derive several rules that determine how to choose images and how to develop algorithms for choosing the most representative images of specific texts. This article describes the user tests and can be a first important step to evaluate automatic tools to select representative images for representing articles and potentially also images in other contexts, for example when representing patient records or other medical concepts when selecting

    Objective: For many literature review tasks, including systematic review (SR) and other aspects of evidence-based medicine, it is important to know whether an article describes a randomized controlled trial (RCT). Current manual annotation is not complete or flexible enough for the SR process. In this work, highly accurate machine learning predictive models were built that include confidence predictions of whether an article is an RCT. Materials and Methods: The LibSVM classifier was used with forward selection of potential feature sets on a large human-related subset of MEDLINE to create a classification model requiring only the citation, abstract, and MeSH terms for each article. Results: The model achieved an area under the receiver operating characteristic curve of 0.973 and mean squared error of 0.013 on the held out year 2011 data. Accurate confidence estimates were confirmed on a manually reviewed set of test articles. A second model not requiring MeSH terms was also created, and performs almost as well. Discussion: Both models accurately rank and predict article RCT confidence. Using the model and the manually reviewed samples, it is estimated that about 8000 (3%) additional RCTs can be identified in MEDLINE, and that 5% of articles tagged as RCTs in Medline may not be identified. Conclusion: Retagging human-related studies with a continuously valued RCT confidence is potentially more useful for article ranking and review than a simple yes/no prediction. The automated RCT tagging tool should offer significant savings of time and effort during the process of writing SRs, and is a key component of a multistep text mining pipeline that we are building to streamline SR workflow. In addition, the model may be useful for identifying errors in MEDLINE publication types.

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. iScore is able to achieve higher quality results than traditional methods such as themore » Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 25% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.« less

    Background Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal tumors and usually presented with locally advanced and distant metastasis disease, which prevent curative resection or treatments. In this regard, we considered identifying molecular subtypes associated with clinicopathological factor as prognosis factors to stratify PDAC for appropriate treatment of patients. Results In this study, we identified three molecular subtypes which were significant on survival time and metastasis. We also identified significant genes and enriched pathways represented for each molecular subtype. Considering R0 resection patients included in each subtype, metastasis and survival times are significantly associated with subtype 1 and subtype 2. Conclusions We observed three PDAC molecular subtypes and demonstrated that those subtypes were significantly related with metastasis and survival time. The study may have utility in stratifying patients for cancer treatment. PMID:25560450

    Motivational interviewing (MI) is a complex intervention comprising multiple techniques aimed at changing health-related motivation and behaviour. However, MI techniques have not been systematically isolated and classified. This study aimed to identify the techniques unique to MI, classify them as content-related or relational, and evaluate the extent to which they overlap with techniques from the behaviour change technique taxonomy version 1 [BCTTv1; Michie, S., Richardson, M., Johnston, M., Abraham, C., Francis, J., Hardeman, W., … Wood, C. E. (2013). The behavior change technique taxonomy (v1) of 93 hierarchically clustered techniques: Building an international consensus for the reporting of behavior change interventions. Annals of Behavioral Medicine, 46, 81-95]. Behaviour change experts (n = 3) content-analysed MI techniques based on Miller and Rollnick's [(2013). Motivational interviewing: Preparing people for change (3rd ed.). New York: Guildford Press] conceptualisation. Each technique was then coded for independence and uniqueness by independent experts (n = 10). The experts also compared each MI technique to those from the BCTTv1. Experts identified 38 distinct MI techniques with high agreement on clarity, uniqueness, preciseness, and distinctiveness ratings. Of the identified techniques, 16 were classified as relational techniques. The remaining 22 techniques were classified as content based. Sixteen of the MI techniques were identified as having substantial overlap with techniques from the BCTTv1. The isolation and classification of MI techniques will provide researchers with the necessary tools to clearly specify MI interventions and test the main and interactive effects of the techniques on health behaviour. The distinction between relational and content-based techniques within MI is also an important advance, recognising that changes in motivation and behaviour in MI is a function of both intervention content and the interpersonal style

    Bibliometric studies are increasingly being utilized as a tool for gauging the impact of different literature within a given field. The purpose of this study was to identify the most cited articles related to the management of distal radius fractures to better understand how the evidence of this topic has been shaped and changed over time. We utilized the ISI web of science database to conduct a search for the term "distal radius fracture" under the "orthopaedics" research area heading, and sorted the results by number of times cited. The 100 most cited articles published in orthopedic journals were then analyzed for number of citations, source journal, year of publication, number of authors, study type, level of evidence, and clinical outcomes utilized. The 100 most cited articles identified were published between 1951 and 2009. Total number of citations ranged between 525 and 67, and came from ten different orthopedic journals. The largest number of articles came from J Hand Surg Am and J Bone Joint Surg Am, each with 32. Consistent with previous analyses of orthopedic literature, the articles were primarily clinical, and of these, 53/76 were case series. The vast majority were evidence level IV. Only a small percentage of articles utilized patient reported outcome measures. These data show that despite distal radius fractures being a common fracture encountered by physicians, very few of the articles were high quality studies, and only a low proportion of the studies include patient reported outcome measures. Surgeons should take this lack of high-level evidence into consideration when referencing classic papers in this field. Analysis of the 100 most cited distal radius fracture articles allows for delineation of which articles are most common in the field and if a higher level of evidence correlates positively with citation quantity.

    There is an abundance of articles published on meningioma. To identify the 100 most-cited articles on meningioma and to perform a bibliometric analysis. In November 2016, we performed a title-specific search of the Scopus database using "meningioma" as our search query term without publication date restrictions. The top 100 most cited articles were obtained and reviewed. The top 100 most cited articles received a mean 198 citations per paper. Publication dates ranged from 1953 to 2013; most articles were published between 1994 and 2003, with 50 articles published during that period. NEUROSURGERY published the greatest number of top cited articles (22 of 100). The most frequent study categories were laboratorial studies (31 of 100) and natural history studies (28 of 100). Nonoperative management studies were twice as common as operative management studies in the top-cited articles. Neurosurgery as a specialty contributed to 50% of the top 100 list. The most contributing institute was the Mayo Clinic (11%); the majority of the top cited articles originated in the United States (53%). We identified the top 100 most-cited articles on meningioma that may be considered significant and impactful works, as well as the most noteworthy. In addition, we recognized the historical development and advances in meningioma research and the important contributions of various authors, specialty fields, and countries. A large proportion of the most cited articles were written by authors other than neurosurgeons, and many of these articles were published in non-neurosurgery journals. Copyright © 2017 Elsevier Inc.

    2000-01-01

    An article is welded, as in weld repair of a defect, by positioning a weld lift-off block at a location on the surface of the article adjacent to the intended location of the end of the weldment on the surface of the article. The weld lift-off block has a wedge shape including a base contacting the surface of the article, and an upper face angled upwardly from the base from a base leading edge. A weld pool is formed on the surface of the article by directly heating the surface of the article using a heat source. The heat source is moved relative to the surface of the article and onto the upper surface of the weld lift-off block by crossing the leading edge of the wedge, without discontinuing the direct heating of the article by the heat source. The heating of the article with the heat source is discontinued only after the heat source is directly heating the upper face of the weld lift-off block, and not the article.

    2018-05-03

    This study aimed to characterize articles in popular general radiology journals that go uncited for a decade after publication. Using the Web of Science database, we identified annual citation counts for 13,459 articles published in Radiology, American Journal of Roentgenology, and Academic Radiology between 1997 and 2006. From this article cohort, we then identified all original research articles that accrued zero citations within a decade of publication. A concurrent equal-sized cohort of most cited articles was created. Numerous characteristics of the uncited and most cited articles were identified and compared. Only 47 uncited articles went uncited for a decade after publication. When compared to the 47 most cited articles over that same window, the uncited articles were significantly (P < .05) less likely to have a clinical focus, include a nonradiologist author and authors from multiple institutions and multiple nations, report research funding support and statistically significant findings, and include punctuation marks in their titles. Compared to the most cited articles, uncited articles also had significantly (P < .05) fewer authors, abstract words, manuscript words, references, tables, figure parts, and pages, as well as smaller subject sample sizes. Of articles published in popular general radiology journals, only a very small number of original research investigations remained uncited a decade after publication. Given that citations reflect the impact of radiology research, this observation suggests that journals are appropriately selecting meaningful work. Investigators seeking to avoid futile publication might consider their research initiatives in light of these characteristics. Copyright © 2018 The Association of University Radiologists.

    2018-06-04

    Codeine dependence is a significant public health problem, motivating the recent rescheduling of codeine in Australia (1 February 2018). To provide information for informing clinical responses, we undertook a systematic review of what is known about identifying and treating codeine dependence. Articles published in English that described people who were codeine-dependent or a clinical approach to treating people who were codeine-dependent, without restriction on year of publication, were reviewed. Articles not including empirical data were excluded. One researcher screened each abstract; two researchers independently reviewed full text articles. Study quality was assessed, and data were extracted with standardised tools. MEDLINE and EMBASE were searched for relevant publications on 22 November 2016. The reference lists of eligible studies were searched to identify further relevant publications. 2150 articles were initially identified, of which 41 were eligible for inclusion in our analysis. Studies consistently reported specific characteristics associated with codeine dependence, including mental health comorbidity and escalation of codeine use attributed to psychiatric problems. Case reports and series described codeine dependence masked by complications associated with overusing simple analgesics and delayed detection. Ten studies described the treatment of codeine dependence. Three reports identified a role for behavioural therapy; the efficacy of CYP inhibitors in a small open label trial was not confirmed in a randomised controlled trial; four case series/chart reviews described opioid agonist therapy and medicated inpatient withdrawal; two qualitative studies identified barriers related to perceptions of codeine-dependent people and treatment providers, and confirmed positive perceptions and treatment outcomes achieved with opioid agonist treatments. Strategies for identifying problematic codeine use are needed. Identifying codeine dependence in clinical

    Datasets of gigabyte size are common in medical sciences. There is increasing consensus that significant untapped knowledge lies hidden in these large datasets. This review article aims to discuss Electronic Health-Related Datasets (EHRDs) in terms of types, features, advantages, limitations, and possible use in nursing and health-related research. Major scientific databases, MEDLINE, ScienceDirect, and Scopus, were searched for studies or review articles regarding using EHRDs in research. A total number of 442 articles were located. After application of study inclusion criteria, 113 articles were included in the final review. EHRDs were categorized into Electronic Administrative Health-Related Datasets and Electronic Clinical Health-Related Datasets. Subcategories of each major category were identified. EHRDs are invaluable assets for nursing the health-related research. Advanced research skills such as using analytical softwares, advanced statistical procedures, dealing with missing data and missing variables will maximize the efficient utilization of EHRDs in research. © The Author(s) 2014.

  20. Identifying Nearby Galaxy Outliers Using Neutral Hydrogen Scaling Relations

    NASA Astrophysics Data System (ADS)

    Galaxies appear to be divided into two distinct families: blue, star-forming, gas-rich, spiral galaxies and red, gas-deficient, elliptical galaxies. However, the transition between these two families is not well understood. A galaxy's gas content could be a good indicator of processes that affect this transition. We assembled a catalog of physical properties for 535 nearby massive galaxies (redshifts 0.025 < z < 0.05; stellar masses M* > 108 solar masses) from various existing surveys to examine their neutral hydrogen (HI) gas content. We obtained HI data (e.g., HI masses and HI radii) from several surveys; other properties (e.g., stellar masses, light radii and star formation rates) were derived from the Sloan Digital Sky Survey (SDSS) and the Galaxy Evolution Explorer (GALEX). Our goal is to identify any outliers from scaling relations derived from galaxies in the GALEX Arecibo SDSS Survey (GASS) in hope that these outliers can provide us with insight into processes relevant to the blue-to-red-galaxy transition. Results indicate that our heterogeneous selection yields a sample that shows similar scaling relations as the GASS galaxies. For example, the atomic HI gas fraction (MHI/M*) decreases strongly as both stellar mass and stellar mass surface density increase. Here, we show recent work that investigates the HI distribution maps of our galaxies to identify environmental effects that might cause outliers to exist.

    Cervical Spondylotic Myelopathy (CSM) occurs due to chronic degenerative changes in the cervical spine causing compression of the spinal cord. CSM has been studied for decades and there are innumerable articles published on the topic. We sought to identify the top 50 most cited articles on CSM. The top 50 cited articles were retrieved from the SCOPUS database using the search criteria "cervical spondylosis with myelopathy" OR "cervical spondylotic myelopathy." Levels of evidence were also calculated. Descriptive and statistical analysis was also carried out. The total number of citations of the top 50 papers was 7072. The paper with the highest number of citations was 287. All articles were published between 1966-2010, with most articles being published between 1990 and 1999(N=22). The most prolific country in terms of the total number of publications was United States with 25 publications followed by Japan. Majority of the articles were Level IV. There is a deficiency of high-level articles in the top 50 most cited list. The study provides an important overview of historical development of treatment methods as well as publication trends related to this pathology. Regardless, this is a comprehensive list of the top 50 most cited articles for future trainees and surgeons to use as resource to build up knowledge base. Copyright © 2018.

    The relationship between diseases and their causative genes can be complex, especially in the case of polygenic diseases. Further exacerbating the challenges in their study is that many genes may be causally related to multiple diseases. This study explored the relationship between diseases through the adaptation of an approach pioneered in the context of information retrieval: vector space models. A vector space model approach was developed that bridges gene disease knowledge inferred across three knowledge bases: Online Mendelian Inheritance in Man, GenBank, and Medline. The approach was then used to identify potentially related diseases for two target diseases: Alzheimer disease and Prader-Willi Syndrome. In the case of both Alzheimer Disease and Prader-Willi Syndrome, a set of plausible diseases were identified that may warrant further exploration. This study furthers seminal work by Swanson, et al. that demonstrated the potential for mining literature for putative correlations. Using a vector space modeling approach, information from both biomedical literature and genomic resources (like GenBank) can be combined towards identification of putative correlations of interest. To this end, the relevance of the predicted diseases of interest in this study using the vector space modeling approach were validated based on supporting literature. The results of this study suggest that a vector space model approach may be a useful means to identify potential relationships between complex diseases, and thereby enable the coordination of gene-based findings across multiple complex diseases.

    We describe the ongoing citations to biomedical articles affected by scientific misconduct, and characterize the papers that cite these affected articles. The citations to 102 articles named in official findings of scientific misconduct during the period of 1993 and 2001 were identified through the Institute for Scientific Information Web of Science database. Using a stratified random sampling strategy, we performed a content analysis of 603 of the 5,393 citing papers to identify indications of awareness that the cited articles affected by scientific misconduct had validity issues, and to examine how the citing papers referred to the affected articles. Fewer than 5% of citing papers indicated any awareness that the cited article was retracted or named in a finding of misconduct. We also tested the hypothesis that affected articles would have fewer citations than a comparison sample; this was not supported. Most articles affected by misconduct were published in basic science journals, and we found little cause for concern that such articles may have affected clinical equipoise or clinical care.

    Magazines are a commonly used source for health and fitness information. Little is known about the nature and extent of weight loss strategies and products presented in mainstream women's health and fitness magazines. This preliminary cross-sectional study evaluated the prevalence of articles and advertisements featuring weight loss content and products in mainstream US-based health and fitness magazines, as well as assessed weight loss themes presented. Thirty-one US health and fitness-focused magazine issues were coded. Prevalence of, product type, and themes related to weight loss in articles and advertisements were assessed. Among the 31 issues of the five US-based women's magazines examined, we identified 39 articles (4.8% [95% CI = 3.3% to 5.5%] of 819 articles) related to weight loss with 14 identified weight loss topics. The most prevalent article topics covered were exercising/workouts (32.0% [95% CI = 28.8% to 33.6%]) followed by dieting (18.6% [95% CI = 15.9% to 19.9%]).The most common product advertised was weight loss pills (46.0% [95% CI = 42.6% to 47.7%]). Fat burners were also frequently advertised (14.9% [95% CI = 12.5% to 16.1%]) followed by hunger reduction strategies (10.3% [95% CI = 8.2% to 11.3%]) and fat blockers (6.9% [95% CI= 5.2% to 7.8%]). Articles presented information about exercise and dieting whereas advertisements supported potentially harmful health beliefs and behaviors. As a well-utilized American media format, health and fitness-focused magazines have an opportunity to communicate frequent,accurate messaging about healthy weight reduction and limit advertisements that may include misleading claims.

    2016-10-01

    The aims of this study are to identify what hinders implementation of the WHO Framework Convention on Tobacco Control (FCTC) Article 5.3 in Korea, and to provide suggestions for the implementation of Article 5.3. Official governmental documents on tobacco control were reviewed. We also searched news articles for data triangulation. There were three factors that hindered the implementation of Article 5.3 in Korea. Firstly, there has been legal conflict between two tobacco-related laws, one of which is designed to promote the tobacco industry. The other is designed to promote public health. Secondly, the government has had economic interests in the tobacco industry, and its lack of action to effectively regulate the tobacco industry's corporate social responsibility (CSR) practices has hindered the implementation of Article 5.3. Thirdly, the tobacco industry's lobby and active interference in the policy-making process has been a barrier. To fully implement Article 5.3, this study suggests: defusing legal conflict between tobacco-related laws; not considering tobacco industry as a stakeholder; regulating tobacco industry's CSR activities; raising awareness of tobacco industry interference; securing transparency between the government and tobacco industry; and establishing a core group or a committee under the government to implement Article 5.3.

    Cancer constitutes a momentous health burden in our society. Critical information on cancer may be hidden in its signaling pathways. However, even though a large amount of money has been spent on cancer research, some critical information on cancer-related signaling pathways still remains elusive. Hence, new works towards a complete understanding of cancer-related signaling pathways will greatly benefit the prevention, diagnosis, and treatment of cancer. We propose the node-weighted Steiner tree approach to identify important elements of cancer-related signaling pathways at the level of proteins. This new approach has advantages over previous approaches since it is fast in processing large protein-protein interaction networks. We apply this new approach to identify important elements of two well-known cancer-related signaling pathways: PI3K/Akt and MAPK. First, we generate a node-weighted protein-protein interaction network using protein and signaling pathway data. Second, we modify and use two preprocessing techniques and a state-of-the-art Steiner tree algorithm to identify a subnetwork in the generated network. Third, we propose two new metrics to select important elements from this subnetwork. On a commonly used personal computer, this new approach takes less than 2 s to identify the important elements of PI3K/Akt and MAPK signaling pathways in a large node-weighted protein-protein interaction network with 16,843 vertices and 1,736,922 edges. We further analyze and demonstrate the significance of these identified elements to cancer signal transduction by exploring previously reported experimental evidences. Our node-weighted Steiner tree approach is shown to be both fast and effective to identify important elements of cancer-related signaling pathways. Furthermore, it may provide new perspectives into the identification of signaling pathways for other human diseases.

    Even though citation analysis has several limitations, it is a commonly used tool to determine the impact of scientific articles in different research fields. The study aims to identify and systematically review the 100 most cited articles in the field of visceral surgery focusing on papers that modified therapeutic concepts and influenced the surgeons' decision making. The 100 most cited clinical articles in visceral surgery were identified using Journal Citation Reports and Science Citation Index Expanded of the Web of Science (Thomson Reuters, Philadelphia, Pa., USA). Data for characterization of the articles were determined: Number of citations, research topic, journal, publication time, authorship, country of origin, type of article and level of evidence if reasonable. The 100 most cited articles were published in 17 journals; 72 articles were found in the 3 journals: New England Journal of Medicine (38), Annals of Surgery (21) and Lancet (13). The oldest article was published in 1908 in Annals of Surgery (ranked 76th) and the most recent in 2012 in Lancet (65th). Eighty articles were published between 1990 and 2010. The number of citations ranged from 667 to 4,666 (median 925). The leading country of origin was the United States with 39 articles, followed by articles originating from more than one country (30). There were 45 interventional studies (27 randomized controlled trials), 32 observational studies, 19 reviews and 4 guidelines, definitions or classifications. The level of evidence was low (IV) in 42 articles and high in 35 articles (Ia or Ib). A high number of citations did not reflect a high level of evidence. The topics and research questions of the identified articles covered a large area of visceral surgery. Some of the milestones in visceral surgery were identified. The high impact measured by citations did not reflect a high quality of research (level of evidence) in a considerable number of publications. © 2016 S. Karger AG, Basel.

    2010-05-01

    Childhood susceptibility to diseases linked with immune dysfunction affects over a quarter of the pediatric population in some countries. While this alone is a significant health issue, the actual impact of immune-related diseases extends over a lifetime and involves additional secondary conditions. Some comorbidities are well known (e.g., allergic rhinitis and asthma). However, no systematic approach has been used to identify life-long patterns of immune-based disease where the primary condition arises in childhood. Such information is useful for both disease prevention and treatment approaches. Recent primary research papers as well as review articles were obtained from PubMed, Chem Abstracts, Biosis and from the personal files of the authors. Search words used were: the diseases and conditions shown Figs. 1 and 2 in conjunction with comorbid, comorbidities, pediatric, childhood, adult, immune, immune dysfunction, allergy, autoimmune, inflammatory, infectious, health risks, environment, risk factors. Childhood diseases such as asthma, type-1 diabetes, inflammatory bowel disease, respiratory infections /rhinitis, recurrent otitis media, pediatric celiac, juvenile arthritis and Kawasaki disease are examples of significant childhood health problems where immune dysfunction plays a significant role. Each of these pediatric diseases is associated with increased risk of several secondary conditions, many of which appear only later in life. To illustrate, four prototypes of immune-related disease patterns (i.e., allergy, autoimmunity, inflammation and infectious disease) are shown as tools for: 1) enhanced disease prevention; 2) improved management of immune-based pediatric diseases; and 3) better recognition of underlying pediatric immune dysfunction. Identification of immune-related disease patterns beginning in childhood provides the framework for examining the underlying immune dysfunctions that can contribute to additional diseases in later life.

    The citation number of an article gives us information about its quality and contribution to science. In this article, we aimed to find the most frequently cited article in general surgery from Turkey, and evaluate how these articles in general surgery contributed to the world literature. We used the science citation index expanded database to find the most frequently cited articles in general surgery from Turkey. Among the 52 articles found, the most common subjects were as follows: hydatid cyst (21.1%), pilonidal disease (15.4%), laparoscopic operations (15.4%), breast diseases (11.5%), and inguinal hernia (7.7%). Two articles were cited in more than 100 articles. Furthermore, 48.8% of the articles were published from three major cities. Most articles were published between 2000 and 2004, and 65.4% of articles were case series. Most of the cited articles were about hydatid cyst and pilonidal disease, which are more common in the Turkish population compared with other countries. Evaluation of most cited articles is important to identify the fields in which Turkey contributes to the world literature.

    How different cultures evaluate a person? Is an important person in one culture is also important in the other culture? We address these questions via ranking of multilingual Wikipedia articles. With three ranking algorithms based on network structure of Wikipedia, we assign ranking to all articles in 9 multilingual editions of Wikipedia and investigate general ranking structure of PageRank, CheiRank and 2DRank. In particular, we focus on articles related to persons, identify top 30 persons for each rank among different editions and analyze distinctions of their distributions over activity fields such as politics, art, science, religion, sport for each edition. We find that local heroes are dominant but also global heroes exist and create an effective network representing entanglement of cultures. The Google matrix analysis of network of cultures shows signs of the Zipf law distribution. This approach allows to examine diversity and shared characteristics of knowledge organization between cultures. The developed computational, data driven approach highlights cultural interconnections in a new perspective. Dated: June 26, 2013.

    The subject of identifying and supporting failing students in community nursing education programmes has been largely overlooked in the literature, yet is of great concern to practice teachers. This article discusses the views on the topic of a group of practice teachers in the light of existing, related research and proposes a number of indicators for good practice. It is suggested that of central importance is the need for higher education institutions and practice teachers to work together in identifying students causing concern at an early stage in their studies, based on both objective and subjective observations, and to have in place documented procedures to be followed when such situations arise.

    Health economic evaluation research plays an important role in selecting cost-effective interventions. The purpose of this study was to assess the quality of published articles in Iranian journals related to economic evaluation in health care programs based on Drummond's checklist in terms of numbers, features, and quality. In the present review study, published articles (Persian and English) in Iranian journals related to economic evaluation in health care programs were searched using electronic databases. In addition, the methodological quality of articles' structure was analyzed by Drummond's standard checklist. Based on the inclusion criteria, the search of databases resulted in 27 articles that fully covered economic evaluation in health care programs. A review of articles in accordance with Drummond's criteria showed that the majority of studies had flaws. The most common methodological weakness in the articles was in terms of cost calculation and valuation. Considering such methodological faults in these studies, it is anticipated that these studies would not provide an appropriate feedback to policy makers to allocate health care resources correctly and select suitable cost-effective interventions. Therefore, researchers are required to comply with the standard guidelines in order to better execute and report on economic evaluation studies.

Although there is a growing body of research concerning Inuit youth, relatively little is known about elderly Inuit. In an effort to bridge this knowledge gap, a systematic review of peer-reviewed journal articles was conducted. This review identified a dearth of research on older Inuit, and highlighted limitations in service provision to this primarily rural and isolated population. Implications for policy and practice and recommendations for future research are also discussed.

    Background: Magazines are a commonly used source for health and fitness information. Little is known about the nature and extent of weight loss strategies and products presented in mainstream women’s health and fitness magazines. Methods: This preliminary cross-sectional study evaluated the prevalence of articles and advertisements featuring weight loss content and products in mainstream US-based health and fitness magazines, as well as assessed weight loss themes presented. Thirty-one US health and fitness-focused magazine issues were coded. Prevalence of, product type, and themes related to weight loss in articles and advertisements were assessed. Results: Among the 31 issues of the five US-based women’s magazines examined, we identified 39 articles (4.8% [95% CI = 3.3% to 5.5%] of 819 articles) related to weight loss with 14 identified weight loss topics. The most prevalent article topics covered were exercising/workouts (32.0% [95% CI = 28.8% to 33.6%]) followed by dieting (18.6% [95% CI = 15.9% to 19.9%]).The most common product advertised was weight loss pills (46.0% [95% CI = 42.6% to 47.7%]). Fat burners were also frequently advertised (14.9% [95% CI = 12.5% to 16.1%]) followed by hunger reduction strategies (10.3% [95% CI = 8.2% to 11.3%]) and fat blockers (6.9% [95% CI= 5.2% to 7.8%]). Conclusion: Articles presented information about exercise and dieting whereas advertisements supported potentially harmful health beliefs and behaviors. As a well-utilized American media format, health and fitness-focused magazines have an opportunity to communicate frequent,accurate messaging about healthy weight reduction and limit advertisements that may include misleading claims.

    It is widely acknowledged that the management of risks associated with chemicals in articles needs to be improved. The EU environmental policy states that environmental damage should be rectified at source. It is therefore motivated that the risk management of substances in articles also takes particular consideration to those substances identified as posing a risk in different environmental compartments. The primary aim of the present study was to empirically analyze to what extent the regulation of chemicals in articles under REACH is coherent with the rules concerning chemicals in the Sewage Sludge Directive (SSD) and the Water Framework Directive (WFD). We also analyzed the chemical variation of the organic substances regulated under these legislations in relation to the most heavily used chemicals. The results show that 16 of 24 substances used in or potentially present in articles and regulated by the SSD or the WFD are also identified under REACH either as a substance of very high concern (SVHC) or subject to some restrictions. However, for these substances we conclude that there is limited coherence between the legislations, since the identification as an SVHC does not in itself encompass any use restrictions, and the restrictions in REACH are in many cases limited to a particular use, and thus all other uses are allowed. Only a minor part of chemicals in commerce is regulated and these show a chemical variation that deviates from classical legacy pollutants. This warrants new tools to identify potentially hazardous chemicals in articles. We also noted that chemicals monitored in the environment under the WFD deviate in their chemistry from the ones regulated by REACH. In summary, we argue that to obtain improved resource efficiency and a sustainable development it is necessary to minimize the input of chemicals identified as hazardous to health or the environment into articles.

    The citations received by a scientific publication have been used as a proxy measurement of scientific quality and in ranking researchers. Although these practices have been observed in several institutes, careful assessment of top-cited articles may provide more insight into exploring their characteristics. The aim of this study was to analyze the top-cited articles in medical education identified by Azer 2015 and explore the characteristics of these articles that can provide insight into their assessment. The most frequently cited articles identified by searching the Web of Science under the category "Education, Scientific Discipline" were included in the analysis. The following issues were further analyzed: 1) comparing the mean yearly citations received by articles published before the year 2000 and those published after, 2) assessing whether there was a correlation between the number of grants, number of authors, number of institutes, or number of countries involved and the number of citations received, 3) assessing the number of female representation in authorship, 4) assessing the representation of none-medical staff in the authorship, and 5) exploring any association between top authors identified and those who were awarded the Karolinska Institutet Prize for research in medical education. Although there was no correlation between the number of citations and the number of years since publications, the mean number of citations received by articles published before the year 2000 varied from zero to 18.2 ± 16.6, whereas for those published after the year 2000 the mean varied from 2.0 ± 2.1 to 35.3 ± 26.8. No correlation was found between the number of citations obtained and number of grants, number of authors, number of institutes, or number of countries involved. Females comprised 50% of the total number of authors. However, no correlation was found between the number of females in authorship and the number of citations obtained. Similarly, the number of

    To identify and examine the characteristics of the 50 top-cited articles in medical education. Two searches were conducted in the Web of Knowledge database in March 2014: a search of medical education journals in the category "Education, Scientific Discipline" (List A) and a keyword search across all journals (List B). Articles identified were reviewed for citation count, country of origin, article type, journal, authors, and publication year. Both lists included 56 articles, not 50, because articles with the same absolute number of citations shared the same rank. The majority of List A articles were published in Academic Medicine (34; 60.7%) and Medical Education (16; 28.6%). In List B, 27 articles (48.2%) were published in medical education journals, 19 (33.9%) in general medicine and surgery journals, and 10 (17.9%) in higher education and educational psychology journals. Twenty-six articles were included in both lists, with different rankings. Reviews and articles constituted the majority of articles; there were only 8 research papers in List A and 13 in List B. Articles mainly originated from the United States, Canada, the Netherlands, and the United Kingdom. The majority were published from 1979 to 2007. There was no correlation between year and citation count. The finding that over half of List B articles were published in nonmedical education journals is consistent with medical education's integrated nature and subspecialty breadth. Twenty of these articles were among their respective non-medical-education journals' 50 top-cited papers, showing that medical education articles can compete with subject-based articles.

    To quantify the relationship between the number of times articles are accessed on the Physiotherapy Evidence Database (PEDro) and the article characteristics. A secondary aim was to examine the relationship between accesses and the number of citations of articles. The study was conducted to derive prediction models for the number of accesses of articles indexed on PEDro from factors that may influence an article's accesses. All articles available on PEDro from August 2014 to January 2015 were included. We extracted variables relating to the algorithm used to present PEDro search results (research design, year of publication, PEDro score, source of systematic review (Cochrane or non-Cochrane)) plus language, subdiscipline of physiotherapy, and whether articles were promoted to PEDro users. Three predictive models were examined using multiple regression analysis. Citation and journal impact factor were downloaded. There were 29,313 articles indexed in this period. We identified seven factors that predicted the number of accesses. More accesses were noted for factors related to the algorithm used to present PEDro search results (synthesis research (i.e., guidelines and reviews), recent articles, Cochrane reviews, and higher PEDro score) plus publication in English and being promoted to PEDro users. The musculoskeletal, neurology, orthopaedics, sports, and paediatrics subdisciplines were associated with more accesses. We also found that there was no association between number of accesses and citations. The number of times an article is accessed on PEDro is partly predicted by how condensed and high quality the evidence it contains is. Copyright © 2017 Chartered Society of Physiotherapy.

    Accredited pharmacists conduct home medicines reviews (HMRs) to detect and resolve potential drug-related problems (DRPs). A commercial expert system, Medscope Review Mentor (MRM), has been developed to assist pharmacists in the detection and resolution of potential DRPs. This study compares types of DRPs identified with the commercial system which uses multiple classification ripple down rules (MCRDR) with the findings of pharmacists. HMR data from 570 reviews collected from accredited pharmacists was entered into MRM and the DRPs were identified. A list of themes describing the main concept of each DRP identified by MRM was developed to allow comparison with pharmacists. Theme types, frequencies, similarity and dissimilarity were explored. The expert system was capable of detecting a wide range of potential DRPs: 2854 themes; compared to pharmacists: 1680 themes. The system identified the same problems as pharmacists in many patient cases. Ninety of 119 types of themes identifiable by pharmacists were also identifiable by software. MRM could identify the same problems in the same patients as pharmacists for 389 problems, resulting in a low overlap of similarity with an averaged Jaccard Index of 0.09. MRM found significantly more potential DRPs than pharmacists. MRM identified a wide scope of DRPs approaching the range of DRPs that were identified by pharmacists. Differences may be associated with system consistency and perhaps human oversight or human selective prioritisation. DRPs identified by the system were still considered relevant even though the system identified a larger number of problems.

    Purpose The purpose of this systematic review was to describe what is known about the diabetes disparity affecting Puerto Rican identified adults living in the continental United States as well as illuminate areas that merit further investigation. Methods The CINAHL and PubMed databases were searched using the keywords Hispanic, Puerto Rican, and type 2 diabetes. Search limits included < 10-year-old, peer-reviewed, systematic reviews, available in the English language. The abstracts of 124 articles were reviewed, and 7 articles were reviewed in depth. Results The Puerto Rican identified Hispanic subgroup is disproportionately affected by diabetes-the diabetes disparity. Puerto Rican identified Hispanic adults are less affected by citizenship status, may be less affected by English proficiency, use health care services differently, and have contextually different fatalistic views of diabetes compared with other Hispanic identified people. Spiritual/religious influences, associated mental health problems, and general cultural practices related to diabetes self-care are understudied in this group. Conclusion Ambiguous use of the term Hispanic should be avoided when describing Hispanic subgroups. Stronger, more robust studies are needed to understand the unique cultural forces influencing the poor diabetes outcomes and individual behaviors that contribute to generally suboptimal diabetes self-care for Puerto Rican adults with type 2 diabetes.

    2007-08-01

    Academic nanoscale science and engineering (NSE) research provides a foundation for nanotechnology innovation reflected in patents. About 60% or about 50,000 of the NSE-related patents identified by "full-text" keyword searching between 1976 and 2004 at the United States Patent and Trademark Office (USPTO) have an average of approximately 18 academic citations. The most cited academic journals, individual researchers, and research articles have been evaluated as sources of technology innovation in the NSE area over the 28-year period. Each of the most influential articles was cited about 90 times on the average, while the most influential author was cited more than 700 times by the NSE-related patents. Thirteen mainstream journals accounted for about 20% of all citations. Science, Nature and Proceedings of the National Academy of Sciences (PNAS) have consistently been the top three most cited journals, with each article being cited three times on average. There is another kind of influential journals, represented by Biosystems and Origin of Life, which have very few articles cited but with exceptionally high frequencies. The number of academic citations per year from ten most cited journals has increased by over 17 times in the interval (1990-1999) as compared to (1976-1989), and again over 3 times in the interval (2000-2004) as compared to (1990-1999). This is an indication of increased used of academic knowledge creation in the NSE-related patents.

    Many articles have been published on pituitary adenomas. Bibliometric analyses are helpful for determining the most impactful studies within a field. To identify the top 100 most-cited articles on pituitary adenomas using the bibliometric analysis method. We searched the Thomson Reuters Web of Science on March 31, 2018. Articles were listed in descending order by the total citation (TC) number, and the most-cited articles on pituitary adenomas were identified and analyzed. The most-cited articles were published between 1970 and 2014, with 1999 as the most prolific year. Growth hormone-secreting pituitary adenoma was the most commonly studied tumor subtype (43%), and in clinical studies, treatment options and follow-up were the most important research focuses (62%). The average number of TCs was 326, and the average number of annual citations (ACs) was 17. More review articles were published in the last decade, and the average number of ACs was higher for this decade than for previous decades. Twenty-one articles were recognized as "Citation Classics" with a TC number>400. Twenty-five journals published the top 100 works; the Journal of Clinical Endocrinology and Metabolism published the most articles (25%). The most articles (43%) were published in the United States. S. Melmed authored the greatest number of publications (14%). Departments of Medicine (32%) and Endocrinology (32%) contributed to the largest number of articles. This study identified the research focuses and trends regarding pituitary adenoma and provides key references for investigators in guiding future pituitary adenoma research.

    To systematically gather from the literature available the quantitative instruments used to assess the sense of smell in studies carried out with children. The present study included a survey in the Pubmed and Bireme platforms and in the databases of MedLine, Lilacs, regional SciELO and Web of Science, followed by selection and critical analysis of the articles found and chosen. We selected original articles related to the topic in question, conducted only with children in Portuguese, English, and Spanish. We excluded studies addressing other phases of human development, exclusively or concurrently with the pediatric population; studies on animals; literature review articles; dissertations; book chapters; case study articles; and editorials. A book report protocol was created for this study, including the following information: author, department, year, location, population/sample, age, purpose of the study, methods, and main results. We found 8,451 articles by typing keywords and identifiers. Out of this total, 5,928 were excluded by the title, 2,366 by the abstract, and 123 after we read the full text. Thus, 34 articles were selected, of which 28 were repeated in the databases, totalizing 6 articles analyzed in this review. We observed a lack of standardization of the quantitative instruments used to assess children's sense of smell, with great variability in the methodology of the tests, which reduces the effectiveness and reliability of the results.

    To develop, assess, and maximize the sensitivity of a search strategy to identify diet and nutrition trials in PubMed using relative recall. We developed a search strategy to identify diet and nutrition trials in PubMed. We then constructed a gold standard reference set to validate the identified trials using the relative recall method. Relative recall was calculated by dividing the number of references from the gold standard our search strategy identified by the total number of references in the gold standard. Our gold standard comprised 298 trials, derived from 16 included systematic reviews. The initial search strategy identified 242 of 298 references, with a relative recall of 81.2% [95% confidence interval (CI): 76.3%, 85.5%]. We analyzed titles and abstracts of the 56 missed references for possible additional terms. We then modified the search strategy accordingly. The relative recall of the final search strategy was 88.6% (95% CI: 84.4%, 91.9%). We developed a search strategy to identify diet and nutrition trials in PubMed with a high relative recall (sensitivity). This could be useful for establishing a nutrition trials register to support the conduct of future research, including systematic reviews. Copyright © 2015 The Authors. Published by Elsevier Inc.

    In this editorial, the author notes that this issue of American Psychologist features a pair of important articles related to newly updated standards for reporting research in psychology in scientific journals, covering both quantitative (Appelbaum et al., 2018) and qualitative (Levitt et al., 2018) research. The increasing breadth and complexity of research, and the importance of communicating it effectively, requires user-friendly resources that can be applied widely to scientific studies. These two articles are intended to serve that purpose, and to encourage thoroughness and accuracy in research reporting, for psychologists and other scientists in broader academic communities. The articles, known as the Journal Article Reporting Standards (JARS) reports, are based on the work of a task force appointed by the American Psychological Association (APA) Publications and Communications Board in 2015.

    PNAS article classification is rooted in long-standing disciplinary divisions that do not necessarily reflect the structure of modern scientific research. We reevaluate that structure using latent pattern models from statistical machine learning, also known as mixed-membership models, that identify semantic structure in co-occurrence of words in the abstracts and references. Our findings suggest that the latent dimensionality of patterns underlying PNAS research articles in the Biological Sciences is only slightly larger than the number of categories currently in use, but it differs substantially in the content of the categories. Further, the number of articles that are listed under multiple categories is only a small fraction of what it should be. These findings together with the sensitivity analyses suggest ways to reconceptualize the organization of papers published in PNAS. PMID:21078953

    A journal is generally considered to be of higher quality to the extent that it publishes articles that are cited. A journal's articles are not all cited equally, however; rather, citations of only a select group of titles accounts for most of a journal's impact factor. This study aimed to identify the characteristics of Emergencias's most highly cited articles and compare their impact to that of papers by other authors in Spain, in Spanish, and internationally in the field of emergency medicine. Between 2008 and 2015, Emergencias published 975 articles, which received 2207 citations. The most-cited article received 52, and the group of 20 most-cited articles accumulated a total of 519 cites (23.5%). Even though Emergencias is published in Spanish and was included in Journal Citation Reports only recently (2008), some of the published articles have had considerable impact. The most-cited article (EVADUR Study) was in the top 2% (98th percentile) of all publications by authors in Spain, and in the top 1% of articles published in Spanish or in emergency medicine.

    2012-01-01

    Background The number of retracted scholarly articles has risen precipitously in recent years. Past surveys of the retracted literature each limited their scope to articles in PubMed, though many retracted articles are not indexed in PubMed. To understand the scope and characteristics of retracted articles across the full spectrum of scholarly disciplines, we surveyed 42 of the largest bibliographic databases for major scholarly fields and publisher websites to identify retracted articles. This study examines various trends among them. Results We found, 4,449 scholarly publications retracted from 1928–2011. Unlike Math, Physics, Engineering and Social Sciences, the percentages of retractions in Medicine, Life Science and Chemistry exceeded their percentages among Web of Science (WoS) records. Retractions due to alleged publishing misconduct (47%) outnumbered those due to alleged research misconduct (20%) or questionable data/interpretations (42%). This total exceeds 100% since multiple justifications were listed in some retraction notices. Retraction/WoS record ratios vary among author affiliation countries. Though widespread, only miniscule percentages of publications for individual years, countries, journals, or disciplines have been retracted. Fifteen prolific individuals accounted for more than half of all retractions due to alleged research misconduct, and strongly influenced all retraction characteristics. The number of articles retracted per year increased by a factor of 19.06 from 2001 to 2010, though excluding repeat offenders and adjusting for growth of the published literature decreases it to a factor of 11.36. Conclusions Retracted articles occur across the full spectrum of scholarly disciplines. Most retracted articles do not contain flawed data; and the authors of most retracted articles have not been accused of research misconduct. Despite recent increases, the proportion of published scholarly literature affected by retraction remains very small

    The purpose of our study was to identify and characterize the 100 most-cited articles in neuroimaging. Based on the database of Journal Citation Reports, we selected 669 journals that were considered as potential outlets for neuroimaging articles. The Web of Science search tools were used to identify the 100 most-cited articles relevant to neuroimaging within the selected journals. The following information was recorded for each article: publication year, journal, category and impact factor of journal, number of citations, number of annual citations, authorship, department, institution, country, article type, imaging technique used, and topic. The 100 most-cited articles in neuroimaging were published between 1980 and 2012, with 1995-2004 producing 69 articles. Citations ranged from 4384 to 673 and annual citations ranged from 313.1 to 24.9. The majority of articles were published in radiology/imaging journals (n=75), originated in the United States (n=58), were original articles (n=63), used MRI as imaging modality (n=85), and dealt with imaging technique (n=45). The Oxford Centre for Functional Magnetic Resonance Imaging of the Brain at John Radcliffe Hospital (n=10) was the leading institutions and Karl J. Friston (n=11) was the most prolific author. Our study presents a detailed list and an analysis of the 100 most-cited articles in the field of neuroimaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

    Bibliometric analysis is a commonly used analytic tool for objective determination of the most influential and peer-recognized articles within a given field. This study is the first bibliometric analysis of the literature in the field of invasive neuromodulation, excluding deep brain stimulation. The objectives of this study are to identify the 50 most cited articles in invasive neuromodulation, provide an overview of the literature to assist in clinical education, and evaluate the effect of impact factor on manuscript recognition. Bibliometric analysis was performed using the Science Citation Index from the Institute for Scientific Information, accessed through the Web of Science. Search terms relevant to the field of invasive neuromodulation were used to identify the 50 most cited journal articles between 1900 and 2016. The median number of citations was 236 (range, 173-578). The most common topics among the articles were vagus nerve stimulation (n = 24), spinal cord stimulation (n = 9), and motor cortex stimulation (n = 6). Median journal impact factor was 5.57. Most of these articles (n = 19) contained level I, II, or III evidence. This analysis provides a brief look into the most cited articles within the field, many of which evaluated innovated procedures and therapies that helped to drive surgical neuromodulation forward. These landmark articles contain vital clinical and educational information that remains relevant to clinicians and students within the field and provide insight into areas of expanding research. Journal impact factor may play a significant role in determining the literary relevance and general awareness of invasive neuromodulation studies. Copyright © 2018 Elsevier Inc. All rights reserved.

The main objective of this analysis was to identify the top 100 cited articles addressing radiation exposure from medical imaging and assess their characteristics. Relevant articles were extracted from the Scopus database after a systematic search by researchers using an iteratively defined Boolean search string. Subsequently, exclusion criteria were applied. A list of top 100 articles was prepared, and articles were ranked according to the citations they had received. No time restriction was applied. Descriptive statistics of the data were compiled. The top-cited articles were published from 1970-2013, with the most articles published in 2009 and 2010 (12 articles in each year). The citations ranged from 107-1888 with a median of 272. Manuscripts from our top-cited list originated from 20 different countries, with contributions made by 158 authors and 160 organizations. Eighty-eight percent of studies evaluated patient-related radiation exposure, 7% health care workers, and 5% both or were not specified. Thirty-two percent of studies examined adult populations, 14% pediatric, and 54% included both populations or did not specify. Seventy-two percent of studies were dedicated to Computed Tomography, 8% to radiography/fluoroscopy, 9% to interventional procedures, 4% to nuclear medicine, and 7% to a combination of 2 or more modalities. The top 100 cited articles in medical imaging related to radiation exposure are diverse, originating from many countries with numerous contributing authors. The most common topics covered involve CT and adult patients. The recent peak in the most-highly cited articles (2010) suggests that increased attention has been devoted to this field in recent years. Based on these results, it would appear that research on radiation exposure in medical imaging is poised to continue expanding

  8. Directionally solidified article with weld repair

    A directionally solidified nickel-base superalloy article has a defect therein extending parallel to the solidification direction. The article is repaired by removing any foreign matter present in the defect, and then heating the article to a repair temperature of from about 60 to about 98 percent of the solidus temperature of the base material in a chamber containing a protective gas that inhibits oxidation of the base material. The defect is filled with a filler metal while maintaining the article at the repair temperature. The filling is accomplished by providing a source of the filler metal of substantially the same composition as the base material of the directionally solidified article, and melting the filler metal into the defect progressively while moving the source of the filler metal relative to the article in a direction parallel to the solidification direction. Optionally, additional artificial heat extraction is accomplished in a heat-flow direction that is within about 45 degrees of the solidification direction, as the filler metal solidifies within the defect. The article may thereafter be heat treated.

    This article uses qualitative methods to describe the domains of health-related quality of life (HRQoL) that adolescent and young adult (AYA) survivors of central nervous system (CNS) tumors identify as important. Survivors clearly attributed aspects of their current HRQoL to their disease or its treatment. We identified 7 key domains of AYA CNS tumor survivorship: physical health, social well-being, mental health, cognitive functioning, health behaviors, sexual and reproductive health, and support systems. Although most aspects of HRQoL that survivors discussed represented new challenges, there were several areas where survivors pointed out positive outcomes. There is a need for a HRQoL tool designed for this population of survivors, given their unique treatment and survivorship experience. Aspects of HRQoL related to cognition, sexual and reproductive health, health behaviors, and support systems are not typically included in generic HRQoL tools but should be assessed for this population. Developing HRQoL measurement instruments that capture the most significant aspects of HRQoL will improve the ability to track HRQoL in AYA CNS tumor survivors and in the long-term management of common sequelae from CNS tumors and their treatments. © 2015 by Association of Pediatric Hematology/Oncology Nurses.

    Endovascular interventions for intracranial aneurysms have evolved substantially over the past several decades. A citation rank list is used to measure the scientific and/or clinical impact of an article. Our objective was to identify and analyze the characteristics of the 100 most cited articles in the field of endovascular therapy for intracranial aneurysms. We performed a retrospective bibliometric analysis between July and August 2017. Articles were searched on the Science Citation Index Expanded database using Web of Science in order to identify the most cited articles in the endovascular therapy of intracranial aneurysms since 1945. Using selected key terms ('intracranial aneurysm', 'aneurysm', 'aneurysmal subarachnoid', 'endovascular', 'coiling', 'stent-assisted', 'balloon-assisted', 'flow-diversion') yielded a total of 16 314 articles. The top 100 articles were identified and analyzed to extract relevant information, including citation count, authorship, article type, subject matter, institution, country of origin, and year of publication. Citations for the top 100 articles ranged from 133 to 1832. All articles were cited an average of 27 times per year. There were 45 prospective studies, including 7 level-II randomized controlled trials. Most articles were published in the 2000s (n=53), and the majority constituted level III or level IV evidence. Half of the top 100 articles arose from the USA. This study provides a comprehensive overview of the most cited articles in the endovascular management of intracranial aneurysms. It recognizes the contributions made by key authors and institutions, providing an important framework to an enhanced understanding of the evidence behind the endovascular treatment of aneurysms. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Exploring the trends in surgical education research offers insight into concerns, developments, and questions researchers are exploring that are relevant to teaching and learning in surgical specialties. We conducted a review of the surgical education literature published between 2002 and 2012. The purpose was 2-fold: to provide an overview of the most frequently cited articles in the field of surgical education during the last decade and to describe the study designs and themes featured in these articles. Articles were identified through Web of Science by using "surgical education" and "English language" as search terms. Using a feature in Web of Science, we tracked the number of citations of any publication. Of the 800 articles produced by the initial search, we initially selected 23 articles with 45 or more citations, and ultimately chose the 20 articles that were most frequently cited for our analysis. Analysis of the most frequently cited articles published in US journals between the years 2002-2012 identified 7 research themes and presented them in order of frequency with which they appear: use of simulation, issues in student/resident assessment, specialty choice, patient safety, team training, clinical competence assessment, and teaching the clinical sciences, with surgical simulation being the central theme. Researchers primarily used descriptive methods. Popular themes in surgical education research illuminate the information needs of surgical educators as well as topics of high interest to the surgical community.

    Chordomas are rare malignant primary tumors of the spine. In the mobile spine and sacrum an en-bloc resection is associated with decreased rates of recurrence. Our objective was to identify the top cited articles in chordoma research and to further analyze characteristics of these articles. In March 2017, we used ISI Web of Science (v5.11, Thomas Reuter, Philadelphia, Pennsylvania, USA) to search for the following key word: "chordoma". Articles were searched from 1900 to 2017. Articles were ranked based on number of citations. The results were evaluated to determine articles most clinically relevant to the management of chordomas. The top 50 articles that met the search criteria were further characterized on the basis of: title, author, citation density, journal of publication, year (and decade) of publication, institution and country of origin and paper topic. A total of 1,043 articles matched the search criteria. The most influential 50 articles were cited 65 to 290 times. The articles were published between 1926 and 2012, and all articles were published in English. Thirty-three publications (66%) originated from the United States and seven (14%) from Italy. Cancer accounted for the most frequent (n=9) destination journal followed by Journal of Bone and Joint Surgery (n=4). A total of 41 institutions contributed to the top 50 articles. The most common article types were: clinical 44% (n=22), papers that combined clinical and pathology findings 18% (n=9) and basic science research 14% (n=7). The top 50 cited articles on chordomas are predominantly clinical papers, arising from the United States and most frequently published in Cancer and Journal of Bone and Joint Surgery .

    A bibliometric review of the literature. Back pain is a global burden that leads people to seek medical service and results in work disability. Numerous studies are published annually to give new insights into back pain. However, characteristics of the high-impact articles on back pain have not been explored. The current study aimed to identify the 100 most cited articles on back pain and determine their characteristics. Back pain is a globally leading cause of work disability. Numerous studies have been published annually to give new insight to back pain. However, comprehensive analysis to identify the most influential articles is not available until now. The Web of Science core database was searched using the subject terms "back NEAR pain," "dorsalgia," "backache," "lumbar NEAR pain," "lumbago," "back NEAR disorder*," "discitis." The searching results were listed by citation times and the top 100 cited articles on back pain were identified. Important information such as author, journal, publishing year, country, institution, and study type were elicited. A total of 44,460 articles on back pain were displayed. Citation times of the enrolled 100 articles ranged from 249 to 1638 with a mean value of 418. The most productive periods were 1991 to 1995 and 1996 to 2000. The journal Spine holds the largest number of 45 articles, followed by Pain with seven articles. A total of 11 countries contribute to the 100 articles and the United States topped the list. None of the high-impact articles were produced in Asian and African. The current citation analysis demonstrated the essential advances in the history of back pain research and determined the influential authors, institutions, countries, and journals that had outstanding contributions to the studies of back pain. 3.

  1. Identifying job characteristics related to employed women's breastfeeding behaviors.

    For employed mothers of infants, reconciliation of work demands and breastfeeding constitutes a significant challenge. The discontinuation of breastfeeding has the potential to result in negative outcomes for the mother (e.g., higher likelihood of obesity), her employer (e.g., increased absenteeism), and her infant (e.g., increased risk of infection). Given previous research findings identifying return to work as a major risk factor for breastfeeding cessation, we investigate what types of job characteristics relate to women's intentions to breastfeed shortly after giving birth and women's actual breastfeeding initiation and duration. Using job titles and job descriptors contained in a large Australian longitudinal cohort data set (N = 809), we coded job titles using the U.S. Department of Labor (DOL)'s Occupational Information Network (O*NET) database and extracted job characteristics. Hazardous working conditions and job autonomy were identified as significant determinants of women's breastfeeding intentions, their initiation of breastfeeding, and ultimately their breastfeeding continuation. Hence, we recommend that human resource professionals, managers, and public health initiatives provide breastfeeding-supportive resources to women who, based on their job characteristics, are at high risk to prematurely discontinue breastfeeding to ensure these mothers have equal opportunity to reap the benefits of breastfeeding.

    2013-01-01

    The Japanese Association of Clinical Cancer Centers recently published the unadjusted 5-year survival rates of patients receiving care at each facility. A primary concern is that the media may cover this topic differently than originally intended. We examined all 13 newspaper articles that addressed the topic to assess their coverage of the public reporting program's key points, which were identified through interviews with the leader of the program. On average, 4.5 of the 10 key points identified were at least superficially covered. Although most articles mentioned the incomparability of the unadjusted data, eight created comparative tables that listed the survival data across facilities and seven sorted the facilities in descending order of survival. Four articles provided potentially misleading descriptions about the use of the relative survival. We concluded that caution is required because newspaper reports may convey potentially contradicting messages and technical details may be described inaccurately.

  11. Patenting human genes: Chinese academic articles' portrayal of gene patents.

    PubMed

    2018-04-24

    The patenting of human genes has been the subject of debate for decades. While China has gradually come to play an important role in the global genomics-based testing and treatment market, little is known about Chinese scholars' perspectives on patent protection for human genes. A content analysis of academic literature was conducted to identify Chinese scholars' concerns regarding gene patents, including benefits and risks of patenting human genes, attitudes that researchers hold towards gene patenting, and any legal and policy recommendations offered for the gene patent regime in China. 57.2% of articles were written by law professors, but scholars from health sciences, liberal arts, and ethics also participated in discussions on gene patent issues. While discussions of benefits and risks were relatively balanced in the articles, 63.5% of the articles favored gene patenting in general and, of the articles (n = 41) that explored gene patents in the Chinese context, 90.2% supported patent protections for human genes in China. The patentability of human genes was discussed in 33 articles, and 75.8% of these articles reached the conclusion that human genes are patentable. Chinese scholars view the patent regime as an important legal tool to protect the interests of inventors and inventions as well as the genetic resources of China. As such, many scholars support a gene patent system in China. These attitudes towards gene patents remain unchanged following the court ruling in the Myriad case in 2013, but arguments have been raised about the scope of gene patents, in particular that the increasing numbers of gene patents may negatively impact public health in China.

  12. Trends in funding, internationalization, and types of study for original articles published in five implant-related journals between 2005 and 2009.

    2012-01-01

    The aims of this study were to evaluate the trends in funding, geographic origin, and study types of original articles in the dental implant literature and to investigate the relationships among these factors. Articles published in Clinical Oral Implants Research, The International Journal of Oral and Maxillofacial Implants, Clinical Implant Dentistry and Related Research, Implant Dentistry, and Journal of Oral Implantology from 2005 to 2009 were reviewed. Nonoriginal articles were excluded. For each article included, extramural funding source, geographic origin, and study type were recorded. Descriptive and analytic analyses (α = .05), including a logistic regression analysis, and chi-square test were used where appropriate. Of a total of 2,085 articles published, 1,503 met the inclusion criteria. The most common source of funding was from industry (32.4%). The proportion of studies that reported funding increased significantly over time. Europe represented the highest percentage (55.8%) of published articles. Most of the articles reported on clinical studies (49.9%), followed by animal studies (25.9%). Articles from Asia and South America and animal and in vitro studies were significantly more likely to be funded. Almost half of the original dental implant articles were funded. The trend toward internationalization of authorship was evident. A strong association was observed between funding and geographic origin and between funding and study type. Most studies in North America and Europe were clinical studies and supported by industry, whereas a greater proportion of studies in Asia and South America were in vitro or animal studies funded through government resources.

  13. Citation rates for experimental psychology articles published between 1950 and 2004: top-cited articles in behavioral cognitive psychology.

    2012-10-01

    From citation rates for over 85,000 articles published between 1950 and 2004 in 56 psychology journals, we identified a total of 500 behavioral cognitive psychology articles that ranked in the top 0.6% in each half-decade, in terms of their mean citations per year using the Web of Science. Thirty nine percent [corrected] of these articles were produced by 78 authors who authored three or more of them, and more than half were published by only five journals.The mean number of cites per year and the total number of citations necessary for an article to achieve various percentile rankings are reported for each journal. The mean number of citations necessary for an article published within each half-decade to rank at any given percentile has steadily increased from 1950 to 2004. Of the articles that we surveyed, 11% had zero total citations, and 35% received fewer than four total citations. Citations for post-1994 articles ranking in the 50th-75th and 90th-95th percentiles have generally continued to grow across each of their 3-year postpublication bins. For pre-1995 articles ranking in the 50th-75th and 90th-95th percentiles, citations peaked in the 4- to 6- or 7- to 9-year postpublication bins and decreased linearly thereafter, until asymptoting. In contrast, for the top-500 articles, (a) for pre-1980 articles, citations grew and peaked 10-18-year postpublication bins, and after a slight decrease began to linearly increase again; (b) for post-1979 articles, citations have continually increased across years in a nearly linear fashion. We also report changes in topics covered by the top-cited articles over the decades.

    2006-06-01

    Mass media is an important source for the general public to obtain health information. Newspapers especially have the advantages of providing a variety of information to a broad range of age groups, with wide regional coverage of both urban and rural areas. The purposes of this study were to review the oral malodor information in Japanese newspapers and to investigate peoples' knowledge on the causes of oral malodor. The Nikkei Database was used to select articles published in five major newspapers over a period of 12 years from 1993 to 2004. "Oral malodor" was used as a key search word. A total of 386 articles which contained oral malodor information were identified and used for the analysis. A questionnaire survey was conducted for the patients who visited a fresh breath clinic (n=295). The average number of articles per year was 32.2 +/- 7.3 and there was not a significant difference among years and months. There were only 25 articles (6.5%) with the central theme of oral malodor. More than half of the articles introduced anti-oral malodor products. The causes of oral malodor were described in 35% of the articles (n=134). Periodontal disease (n=57), tongue coating (n=35), otorhinolaryngological diseases (n=19), stomach problems (n=14) and psychological factors (n=21) were described as the causes of malodor. Only 35 articles (26%) described the treatment and prevention of halitosis. According to the questionnaire survey, 39% of the patients answered that they did not know the causes of malodor. Less than half knew that oral problems were related with malodor. It was revealed that the information about oral malodor in newspapers was not enough both quantitatively and qualitatively; people had little information about oral malodor. It is suggested that dental professionals should be aware of the importance of media advocacy to provide appropriate oral health information to the public.

    The aim of the study was assessment of defaults and conducted meta-analysis of the efficacy of single-dose oral albendazole against T. trichiura infection. We searched PubMed, ISI Web of Science, Science Direct, the Cochrane Central Register of Controlled Trials, and WHO library databases between 1983 and 2014. Data from 13 clinical trial articles were used. Each article was included the effect of single oral dose (400 mg) albendazole and placebo in treating two groups of patients with T. trichiura infection. For both groups in each article, sample size, the number of those with T. trichiura infection, and the number of those recovered following the intake of albendazole were identified and recorded. The relative risk and variance were computed. Funnel plot, Beggs and Eggers tests were used for assessment of publication bias. The random effect variance shift outlier model and likelihood ratio test were applied for detecting outliers. In order to detect influence, DFFITS values, Cook's distances and COVRATIO were used. Data were analyzed using STATA and R software. The article number 13 and 9 were outlier and influence, respectively. Outlier is diagnosed by variance shift of target study in inferential method and by RR value in graphical method. Funnel plot and Beggs test did not show the publication bias ( P =0.272). However, the Eggers test confirmed it ( P =0.034). Meta-analysis after removal of article 13 showed that relative risk was 1.99 (CI 95% 1.71 - 2.31). The estimated RR and our meta-analyses show that treatment of T. trichiura with single oral doses of albendazole is unsatisfactory. New anthelminthics are urgently needed.

    Descriptive assessment methods have been used in applied settings to identify consequences for problem behavior, thereby aiding in the design of effective treatment programs. Consensus has not been reached, however, regarding the types of data or analytic strategies that are most useful for describing behavior–consequence relations. One promising approach involves the analysis of conditional probabilities from sequential recordings of behavior and events that follow its occurrence. In this paper we review several strategies for identifying contingent relations from conditional probabilities, and propose an alternative strategy known as a contingency space analysis (CSA). Step-by-step procedures for conducting and interpreting a CSA using sample data are presented, followed by discussion of the potential use of a CSA for conducting descriptive assessments, informing intervention design, and evaluating changes in reinforcement contingencies following treatment.

  2. An algorithm to identify functional groups in organic molecules.

    PubMed

    Ertl, Peter

    2017-06-07

    The concept of functional groups forms a basis of organic chemistry, medicinal chemistry, toxicity assessment, spectroscopy and also chemical nomenclature. All current software systems to identify functional groups are based on a predefined list of substructures. We are not aware of any program that can identify all functional groups in a molecule automatically. The algorithm presented in this article is an attempt to solve this scientific challenge. An algorithm to identify functional groups in a molecule based on iterative marching through its atoms is described. The procedure is illustrated by extracting functional groups from the bioactive portion of the ChEMBL database, resulting in identification of 3080 unique functional groups. A new algorithm to identify all functional groups in organic molecules is presented. The algorithm is relatively simple and full details with examples are provided, therefore implementation in any cheminformatics toolkit should be relatively easy. The new method allows the analysis of functional groups in large chemical databases in a way that was not possible using previous approaches. Graphical abstract .

    To provide a summary of published survey articles regarding the provision of medication therapy management (MTM) services in the United States. A literature search was conducted to identify original articles on MTM-related surveys conducted in the United States, involving community and outpatient pharmacists, physicians, patients, or pharmacy students and published by the primary researchers who conducted the study. Search engines used included PubMed, Medline, and International Pharmaceutical Abstracts (IPA). If MTM was in the keyword list, mesh heading, title, or abstract, the article was reviewed. References from these articles were searched to determine whether other relevant articles were available. A total of 405 articles were initially reviewed; however, only 32 articles met the study requirements. Of the 32 articles, 17 surveyed community/outpatient pharmacists, 3 surveyed pharmacy students, 4 surveyed physicians, and 8 surveyed patients. The survey periods varied across the different studies, with the earliest survey conducted in 2004 and the most recent survey conducted in 2009. The surveys were conducted via the telephone, US mail, interoffice mail, e-mails, Internet/Web sites, hand-delivered questionnaires, and focus groups. Despite the identified barriers to the provision of MTM services, pharmacists reportedly found it professionally rewarding to provide these services. Pharmacists claimed to have adequate clinical knowledge, experience, and access to information required to provide MTM services. Pharmacy students were of the opinion that the provision of MTM services was important to the advancement of the pharmacy profession and in providing patients with a higher level of care. Physicians supported having pharmacists adjust patients’ drug therapy and educate patients on general drug information but not in selecting patients’ drug therapy. Finally, patients suggested that alternative ways need to be explored in describing and marketing MTM

    2016-12-01

    This study aimed to assess the performance of a text classification machine-learning model in predicting highly cited articles within the recent radiological literature and to identify the model's most influential article features. We downloaded from PubMed the title, abstract, and medical subject heading terms for 10,065 articles published in 25 general radiology journals in 2012 and 2013. Three machine-learning models were applied to predict the top 10% of included articles in terms of the number of citations to the article in 2014 (reflecting the 2-year time window in conventional impact factor calculations). The model having the highest area under the curve was selected to derive a list of article features (words) predicting high citation volume, which was iteratively reduced to identify the smallest possible core feature list maintaining predictive power. Overall themes were qualitatively assigned to the core features. The regularized logistic regression (Bayesian binary regression) model had highest performance, achieving an area under the curve of 0.814 in predicting articles in the top 10% of citation volume. We reduced the initial 14,083 features to 210 features that maintain predictivity. These features corresponded with topics relating to various imaging techniques (eg, diffusion-weighted magnetic resonance imaging, hyperpolarized magnetic resonance imaging, dual-energy computed tomography, computed tomography reconstruction algorithms, tomosynthesis, elastography, and computer-aided diagnosis), particular pathologies (prostate cancer; thyroid nodules; hepatic adenoma, hepatocellular carcinoma, non-alcoholic fatty liver disease), and other topics (radiation dose, electroporation, education, general oncology, gadolinium, statistics). Machine learning can be successfully applied to create specific feature-based models for predicting articles likely to achieve high influence within the radiological literature.

    2016-03-01

    In this article we examine the treatment of psychosocial risks in public occupational health discourse in Finnish newspaper and magazine articles between the 1960s and 2000s, using discourse analysis. Building on class theories, our aim is to investigate how class expectations have been linked with the redefinition of occupational health risks during this period. Our results suggest that as social relations at the workplace became problematised in the occupational health discussions after the 1970s, the image of the hierarchical and naturally conflictual organisation was replaced by idealised middle-class notions of smoothly functioning, harmonious organisations that offered rewarding work experiences. However, this same period since the late 1970s has also been characterised by increasing economic competition and neoliberal market ideology. We conclude that the concern about work-related psychosocial risks and health problems expressed in Finnish newspaper and magazine articles during the last three decades has been shaped in many respects by a collision between the dominant middle-class expectations of harmony and equality and the neoliberal production of competition and inequality. © 2015 Foundation for the Sociology of Health & Illness.

    The objective of this study was to identify the most-cited peer-reviewed combat orthopedic and extremity injury articles published during the past 70 years. Orthopedic trauma presents ongoing challenges to both US civilian and military healthcare personnel. Improvements in combat trauma and extremity injury survival and quality of life are the result of advances in orthopedic trauma research. The Web of Science (including Science Citation Index) was searched for the most cited articles related to combat orthopedic trauma, published from 1940 to 2013. The most-cited article was by Owens et al. (Journal of Orthopaedic Trauma, 2007; 137 citations). Between the 1990s and 2000s, there was a 256% increase in the number of highly cited publications. A total of 69% of the articles were on the topics of comorbid vascular trauma (25%), epidemiology (23%), or orthopedic trauma (21%). This study identifies some of the most important contributions to combat orthopedic trauma and research and the areas of greatest scientific interest to the specialty during the past seven decades and highlights key research that has contributed to the evolution of modern combat orthopedic traumatology. 2017.

    The purpose of this study was to review health information on nutrition in Japanese newspaper articles. The Nikkei Database was used to select articles published in five major newspapers: Asahi, Sankei, Nikkei, Mainichi and Yomiuri. All these dailies have nationwide circulation. The search period was for 7 years, from January 1993 to December 1999. The keywords "diet," "health," and "nutrition" were used. Consequently, 182 articles were selected and analyzed by determining content and coverage. The articles were published to be targeted for the general population: 123 (67.6%), schoolchildren: 21 (11.5%), and elderly: 18 (9.9%). The main source of the newspaper articles on diet was health professionals, such as nutritionists and medical doctors. As diet related health problems, the lifestyle-related diseases, obesity, hypertension, and mental health were introduced in the newspapers. Few articles commented on the relationship between oral health and diet, and dental professionals were not much involved in providing health information on diet. The newspaper is a major source for the general public to obtain health information. It is clear that oral diseases and functional disorder influence daily eating habits. It was suggested that dental professionals should provide such information to the general public, using many occasions, such as conducting health guidance at dental clinics, health education at health centers or schools, and also through mass media.

    Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

    Although cognitive behavioural therapy and graded exercise treatment are recognized evidence-based treatments for chronic fatigue syndrome/myalgic encephalomyelitis (ME), their use is still considered controversial by some patient groups. This debate has been reflected in the media, where many patients gather health information. The aim of this study was to examine how treatment for chronic fatigue syndrome/ME is described in the newspaper media. Content analysis of newspaper articles. The digitalized media archive Atekst was used to identify Norwegian newspaper articles where chronic fatigue syndrome/ME was mentioned. Norwegian newspaper articles published over a 20-month period, from 1 January 2008 to 31 August 2009. Statements regarding efficiency of various types of treatment for chronic fatigue syndrome/ME and the related source of the treatment advice. Statements were categorized as being either positive or negative towards evidence-based or alternative treatment. One hundred and twenty-two statements regarding treatment of chronic fatigue syndrome/ME were identified among 123 newspaper articles. The most frequent statements were positive statements towards alternative treatment Lightning Process (26.2%), negative statements towards evidence-based treatments (22.1%), and positive statements towards other alternative treatment interventions (22.1%). Only 14.8% of the statements were positive towards evidence-based treatment. Case-subjects were the most frequently cited sources, accounting for 35.2% of the statements, followed by physicians and the Norwegian ME association. Statements regarding treatment for chronic fatigue syndrome/ME in newspapers are mainly pro-alternative treatment and against evidence-based treatment. The media has great potential to influence individual choices. The unbalanced reporting of treatment options for chronic fatigue syndrome/ME in the media is potentially harmful.

  11. Rule-based deduplication of article records from bibliographic databases.

    We recently designed and deployed a metasearch engine, Metta, that sends queries and retrieves search results from five leading biomedical databases: PubMed, EMBASE, CINAHL, PsycINFO and the Cochrane Central Register of Controlled Trials. Because many articles are indexed in more than one of these databases, it is desirable to deduplicate the retrieved article records. This is not a trivial problem because data fields contain a lot of missing and erroneous entries, and because certain types of information are recorded differently (and inconsistently) in the different databases. The present report describes our rule-based method for deduplicating article records across databases and includes an open-source script module that can be deployed freely. Metta was designed to satisfy the particular needs of people who are writing systematic reviews in evidence-based medicine. These users want the highest possible recall in retrieval, so it is important to err on the side of not deduplicating any records that refer to distinct articles, and it is important to perform deduplication online in real time. Our deduplication module is designed with these constraints in mind. Articles that share the same publication year are compared sequentially on parameters including PubMed ID number, digital object identifier, journal name, article title and author list, using text approximation techniques. In a review of Metta searches carried out by public users, we found that the deduplication module was more effective at identifying duplicates than EndNote without making any erroneous assignments.

    2016-08-01

    Millions of Americans encounter access barriers to medication due to cost; however, to date, there is no effective screening tool that identifies patients at risk of cost-related medication non-adherence (CRN). By utilizing a big-data approach to combining the survey data and electronic health records (EHRs), this study aimed to develop a method of identifying patients at risk of CRN. CRN data were collected by surveying patients about CRN behaviors in the past 3 months. By matching the dates of patients' receipt of monthly Social Security (SS) payments and the dates of prescription orders for 559 Medicare beneficiaries who were primary SS claimants at high risk of hospitalization in an urban academic medical center, this study identified patients who ordered their outpatient prescription within 2 days of receipt of monthly SS payments in 2014. The predictive power of this information on CRN was assessed using multivariate logistic regression analysis. Among the 559 Medicare patients at high risk of hospitalization, 137 (25%) reported CRN. Among those with CRN, 96 (70%) had ordered prescriptions on receipt of SS payments one or more times in 2014. The area under the Receiver Operating Curve was 0.70 using the predictive model in multivariate logistic regression analysis. With a new approach to combining the survey data and EHR data, patients' behavior in delaying filling of prescription until funds from SS checks become available can be measured, providing some predictive value for cost-related medication non-adherence. The big-data approach is a valuable tool to identify patients at risk of CRN and can be further expanded to the general population and sub-populations, providing a meaningful risk-stratification for CRN and facilitating physician-patient communication to reduce CRN.

    The goal of our study was to compile a list of the top 100 most-cited articles in stroke imaging literature across all peer-reviewed scientific journals. These articles were then analyzed to identify current trends in stroke imaging research and determine the characteristics of highly-cited articles. A database of the top 100 most-cited articles was created using Scopus and Web of Science. Articles were reviewed for applicability by 2 fellowship-trained radiologists with over 10 years of combined experience in neuroimaging. The following information was collected from each article: Article Title, Scopus Citations, Year of Publication, Journal, Journal Impact Factor, Authors, Number of Institutions, Country of Origin, Study Topic, Study Design, and Sample Size. Citations for the top 100 most-cited articles ranged from 159-810, and citations per year ranged from 5.7-516.0. Most of articles were published between 1996 and 2000 (n = 43). Articles were published across 18 journals, most commonly in Stroke (n = 40). Magnetic resonance imaging was the focus in 46 articles, computed tomogrphy in 16, and functional magnetic resonance imaging in 10. The most common study topic is prognostic use of an imaging modality (n = 27). Our study helps to characterize the field and identify the characteristics of most-cited articles.

    The number of citations an article receives after its publication reflects its impact in the scientific community. The aim of this study was to identify and characterize the 100 top-cited articles published in radiology journals. The top-cited articles published in 12 radiology journals were identified using the database of Science Citation Index Expanded (1945-2012). The 100 top-cited articles were selected and analyzed with regard to the number of citations, year of publication, publishing journal, authorship, institution and country of origin, type of article, radiologic subspecialty, main topic, and radiologic technique. The 100 top-cited articles were published in eight radiology journals, led by Radiology (n=67) and followed by the American Journal of Roentgenology (n=11). These articles were published between 1939 and 2006 with a mean of 664.3 citations per article (range, 371-6931). Seventy-eight articles were published after 1979, 57 originated from the United States, and 69 were original articles. The most common subspecialties of study were interventional radiology (n=19), neuroradiology (n=15), and breast imaging (n=11). The main topics of articles were radiofrequency ablation of hepatic tumors (n=9), followed by receiver operating characteristic curves (n=6). Our study presents a detailed list and analysis of the 100 top-cited articles published in radiology journals, which provides insight into historical developments in the field of radiology.

    Media coverage and reports have a major influence on individual vaccination and other health-related activities. People use the media to seek information and knowledge on health-related behaviors. They obtain health-related information from media such as television and newspapers, and they trust such information. While several studies have examined the relation between media coverage and individual health, there is a lack of studies that have analyzed media reports of health information. In particular, we have found no analyses related to cervical cancer (human papillomavirus [HPV]) vaccine. This study aimed to identify mentions of cervical cancer vaccine in Japan's printed news media and to determine their characteristics. We used the archival databases of 2 Japanese newspapers, Yomiuri Shimbun (Yomidasu Rekishikan) and Asahi Shimbun (Kikuzo II Visual), for text mining. First, we created a database by extracting articles published between January 1, 2007, and December 31, 2014, that matched the terms "cervical cancer" AND "vaccination" in a keyword search. Then, we tallied the extracted articles based on the month of publication and number of characters in order to conduct a time-series analysis. We extracted a total of 219 articles. Of these, 154 (70.3%) were positive and 51 (23.3%) were negative toward HPV vaccination. Of the 51 negative articles, 4 (7.8%) were published before June 2013, when routine vaccination was temporarily discontinued due to concerns regarding side effects, and 47 (92.2%) were published since then. The negative reports commonly cited side effects, although prior to June 2013, these issues were hardly mentioned. Although foreign media reports mentioned side effects before routine vaccination was temporarily discontinued, fewer articles mentioned side effects than recommendations for vaccination. Furthermore, on June 13, 2013, the World Health Organization's advisory body Global Advisory Committee on Vaccine Safety issued a statement

    [Purpose] This review article is designed to expose physiotherapists to a physiotherapy assessment of stress urinary incontinence (SUI) and the treatment and possibly preventive roles that they might play for women with SUI. Specifically, the goal of this article is to provide an understanding of pelvic floor muscle function and the implications that this function has for physiotherapy treatment by reviewing articles published in this area. [Methods] A range of databases was searched to identify articles that address physiotherapy for SUI, including the Cochrane Library, Medline, and CINAHL. [Results] According to the articles identified in our databases research, greater improvements in SUI occur when women receive a supervised exercise program of at least three months. The effectiveness of physiotherapy treatment is increased if the exercise program is based on some principles, such as intensity, duration, resembling functional task, and the position in which the exercise for pelvic floor muscles is performed. Biofeedback and electrical stimulation may also be clinically useful and acceptable modalities for some women with SUI. [Conclusion] We concluded that the plan for physiotherapy care should be individualized for each patient and include standard physiotherapy interventions. PMID:25276044

    The health and well-being of migrant workers from low-income countries is often neglected in travel medicine. This article uses Nepal as a case study to highlight key issues affecting this particular group of international travellers. This narrative review used a comprehensive systematic literature search to identify relevant studies on Nepal. The included articles were thematically analysed leading to four key themes or risk factors. The search found 18 articles from which we identified 3 key themes related directly to migrant workers: (1) sexual risk taking; (2) occupational health and (3) lifestyles, and a fourth theme related to partners and family of migrant workers who are left behind in Nepal. Of the 18 included articles, 11 articles discussed sexual risk taking and HIV, whilst considerably fewer focused on work-related risk factors and lifestyle factors in migrant workers. Migrant workers who are generally healthy appear to be similar to tourist travellers in regarding sexual health as a key issue related to being abroad. Risky sexual behaviour increases in individuals separated from their usual sexual partners, away from their own communities and families, leading to the so-called 'situational disinhibition'. Considering the recent media coverage of deaths and injuries among migrant workers in the Middle East, it is interesting to see that their sexual health is more prevalent in the research literature. This article argues that travel medicine should provide more emphasis to the health and well-being of migrant workers as a highly vulnerable group of travellers with additional impact on the health of those left behind. © International Society of Travel Medicine, 2017.

    2010-01-01

    Three experiments using online processing measures explored whether native and non-native Spanish-speaking adults use gender-marked articles to identify referents of target nouns more rapidly, as shown previously with 3-year-old children learning Spanish as L1 (Lew-Williams & Fernald, 2007). In Experiment 1, participants viewed familiar objects with names of either the same or different grammatical gender while listening to Spanish sentences referring to one object. L1 adults, like L1 children, oriented to the target more rapidly on different-gender trials, when the article was informative about noun identity; however, L2 adults did not. Experiments 2 and 3 controlled for frequency of exposure to article-noun pairs by using novel nouns. L2 adults could not exploit gender information when different article-noun pairs were used in teaching and testing. Experience-related factors may influence how L1 adults and children and L2 adults—who learned Spanish at different ages and in different settings—use grammatical gender in realtime processing.

    Health economic evaluation research plays an important role in selecting cost-effective interventions. The purpose of this study was to assess the quality of published articles in Iranian journals related to economic evaluation in health care programs based on Drummond’s checklist in terms of numbers, features, and quality. In the present review study, published articles (Persian and English) in Iranian journals related to economic evaluation in health care programs were searched using electronic databases. In addition, the methodological quality of articles’ structure was analyzed by Drummond’s standard checklist. Based on the inclusion criteria, the search of databases resulted in 27 articles that fully covered economic evaluation in health care programs. A review of articles in accordance with Drummond’s criteria showed that the majority of studies had flaws. The most common methodological weakness in the articles was in terms of cost calculation and valuation. Considering such methodological faults in these studies, it is anticipated that these studies would not provide an appropriate feedback to policy makers to allocate health care resources correctly and select suitable cost-effective interventions. Therefore, researchers are required to comply with the standard guidelines in order to better execute and report on economic evaluation studies. PMID:29234174

    The purpose of this study was to identify and characterize the most-cited articles on headache disorders published in journals that have made key contributions in the field. We performed a search of journals and selected the top-100 cited articles by utilizing the Institute for Scientific Information database available under the banner of the Web of Science, which provides the most relevant bibliometric information on scientific articles published since 1950. The top-100 cited articles were published in 20 journals. The most frequently cited journal was Neurology (19 articles), and followed by Cephalagia (15 articles) and Headache (15 articles). Migraine was the most common topic subject (81 articles), and original articles predominated (91 articles). The topics of the classic articles had varied from decade to decade. The most common topic subject was epidemiology (37 articles), followed by pathophysiology (20 articles), treatment (18 articles), review (10 articles), neuroimaging (11 articles), genetics (3 articles), and diagnostic tools (2 articles). The present study has produced a detailed list of the most-cited articles on headache disorders, which is the first such study in this field. This list makes it possible to recognize the classic articles on headache disorders as well as research trends and academic achievements in this field. Copyright © 2017. Published by Elsevier B.V.

  8. Method for hot press forming articles

    1982-01-01

    This disclosure relates to an improved method for achieving the best bond strength and for minimizing distortion and cracking of hot pressed articles. In particular, in a method for hot press forming both an outer facing circumferential surface of and an inner portion of a hub, and of bonding that so-formed outer facing circumferential surface to an inner facing circumferential surface of a pre-formed ring thereby to form an article, the following improvement is made. Normally, in this method, the outside ring is restrained by a restraining sleeve of ring-shaped cross-section having an inside diameter. A die member, used to hot press form the hub, is so-formed as to have an outside diameter sized to engage the inside diameter of the restraining sleeve in a manner permitting relative movement therebetween. The improved method is one in which several pairs of matched restraining sleeve and die member are formed with each matched pair having a predetermined diameter. The predetermined diameter of each matched pair is different from another matched pair by stepped increments. The largest inside diameter of a restraining sleeve is equal to the diameter of the outer facing circumferential surface of the hub. Each pair of the matched restraining sleeve and die member is used to form an article in which an inside hub is bonded to an outside ring. The several samples so-formed are evaluated to determine which sample has the best bond formed between the hub and the ring with the least or no cracking or distortion in the ring portion of the article. Thereafter, the matched restraining sleeve and die member which form the article having the best bonding characteristics and least distortion cracking is then used for repeated formations of articles.

    Knowledge on interactions between molecules in living cells is indispensable for theoretical analysis and practical applications in modern genomics and molecular biology. Building such networks relies on the assumption that the correct molecular interactions are known or can be identified by reading a few research articles. However, this assumption does not necessarily hold, as truth is rather an emerging property based on many potentially conflicting facts. This paper explores the processes of knowledge generation and publishing in the molecular biology literature using modelling and analysis of real molecular interaction data. The data analysed in this article were automatically extracted from 50000 research articles in molecular biology using a computer system called GeneWays containing a natural language processing module. The paper indicates that truthfulness of statements is associated in the minds of scientists with the relative importance (connectedness) of substances under study, revealing a potential selection bias in the reporting of research results. Aiming at understanding the statistical properties of the life cycle of biological facts reported in research articles, we formulate a stochastic model describing generation and propagation of knowledge about molecular interactions through scientific publications. We hope that in the future such a model can be useful for automatically producing consensus views of molecular interaction data.

    The aim of this work was to identify the key mechanisms governing transport of organic chemical substances from consumer articles to cotton wipes. The results were used to establish a mechanistic model to improve assessment of dermal contact exposure. Four types of PVC flooring, 10 types of textiles and one type of inkjet printed paper were used to establish the mechanisms and model. Kinetic extraction studies in methanol demonstrated existence of matrix diffusion and indicated the presence of a substance surface layer on some articles. Consequently, the proposed substance transfer model considers mechanical transport from a surface film and matrix diffusion in an article with a known initial total substance concentration. The estimated chemical substance transfer values to cotton wipes were comparable to the literature data (relative transfer ∼ 2%), whereas relative transfer efficiencies from spiked substrates were high (∼ 50%). For consumer articles, high correlation (r(2)=0.92) was observed between predicted and measured transfer efficiencies, but concentrations were overpredicted by a factor of 10. Adjusting the relative transfer from about 50% used in the model to about 2.5% removed overprediction. Further studies are required to confirm the model for generic use.

  14. In the pursuit of a semantic similarity metric based on UMLS annotations for articles in PubMed Central Open Access.

    2015-10-01

    Although full-text articles are provided by the publishers in electronic formats, it remains a challenge to find related work beyond the title and abstract context. Identifying related articles based on their abstract is indeed a good starting point; this process is straightforward and does not consume as many resources as full-text based similarity would require. However, further analyses may require in-depth understanding of the full content. Two articles with highly related abstracts can be substantially different regarding the full content. How similarity differs when considering title-and-abstract versus full-text and which semantic similarity metric provides better results when dealing with full-text articles are the main issues addressed in this manuscript. We have benchmarked three similarity metrics - BM25, PMRA, and Cosine, in order to determine which one performs best when using concept-based annotations on full-text documents. We also evaluated variations in similarity values based on title-and-abstract against those relying on full-text. Our test dataset comprises the Genomics track article collection from the 2005 Text Retrieval Conference. Initially, we used an entity recognition software to semantically annotate titles and abstracts as well as full-text with concepts defined in the Unified Medical Language System (UMLS®). For each article, we created a document profile, i.e., a set of identified concepts, term frequency, and inverse document frequency; we then applied various similarity metrics to those document profiles. We considered correlation, precision, recall, and F1 in order to determine which similarity metric performs best with concept-based annotations. For those full-text articles available in PubMed Central Open Access (PMC-OA), we also performed dispersion analyses in order to understand how similarity varies when considering full-text articles. We have found that the PubMed Related Articles similarity metric is the most suitable for

  15. Predicting clicks of PubMed articles.

    Predicting the popularity or access usage of an article has the potential to improve the quality of PubMed searches. We can model the click trend of each article as its access changes over time by mining the PubMed query logs, which contain the previous access history for all articles. In this article, we examine the access patterns produced by PubMed users in two years (July 2009 to July 2011). We explore the time series of accesses for each article in the query logs, model the trends with regression approaches, and subsequently use the models for prediction. We show that the click trends of PubMed articles are best fitted with a log-normal regression model. This model allows the number of accesses an article receives and the time since it first becomes available in PubMed to be related via quadratic and logistic functions, with the model parameters to be estimated via maximum likelihood. Our experiments predicting the number of accesses for an article based on its past usage demonstrate that the mean absolute error and mean absolute percentage error of our model are 4.0% and 8.1% lower than the power-law regression model, respectively. The log-normal distribution is also shown to perform significantly better than a previous prediction method based on a human memory theory in cognitive science. This work warrants further investigation on the utility of such a log-normal regression approach towards improving information access in PubMed.

    Objectives Although cognitive behavioural therapy and graded exercise treatment are recognized evidence-based treatments for chronic fatigue syndrome/myalgic encephalomyelitis (ME), their use is still considered controversial by some patient groups. This debate has been reflected in the media, where many patients gather health information. The aim of this study was to examine how treatment for chronic fatigue syndrome/ME is described in the newspaper media. Design Content analysis of newspaper articles. Setting The digitalized media archive Atekst was used to identify Norwegian newspaper articles where chronic fatigue syndrome/ME was mentioned. Participants Norwegian newspaper articles published over a 20-month period, from 1 January 2008 to 31 August 2009. Main outcome measures Statements regarding efficiency of various types of treatment for chronic fatigue syndrome/ME and the related source of the treatment advice. Statements were categorized as being either positive or negative towards evidence-based or alternative treatment. Results One hundred and twenty-two statements regarding treatment of chronic fatigue syndrome/ME were identified among 123 newspaper articles. The most frequent statements were positive statements towards alternative treatment Lightning Process (26.2%), negative statements towards evidence-based treatments (22.1%), and positive statements towards other alternative treatment interventions (22.1%). Only 14.8% of the statements were positive towards evidence-based treatment. Case-subjects were the most frequently cited sources, accounting for 35.2% of the statements, followed by physicians and the Norwegian ME association. Conclusions Statements regarding treatment for chronic fatigue syndrome/ME in newspapers are mainly pro-alternative treatment and against evidence-based treatment. The media has great potential to influence individual choices. The unbalanced reporting of treatment options for chronic fatigue syndrome/ME in the media is

    To identify strategies to assist in the publication of research arising from a postgraduate thesis or dissertation. There are many benefits to publishing a journal article from a completed thesis, including contributing knowledge to the writer's chosen field, career enhancement and personal satisfaction. However, there are also numerous obstacles for the newly graduated student in crafting an article fit for a specialist publication from a thesis. The author conducted a search of the title, abstract and keywords of the Cinahl, Scopus and Proquest databases, from 1990 to 2010: The author searched for the words: 'journal article' or 'manuscript; 'thesis' or 'dissertation'. The author excluded papers if: they pertained to allocation of authorship to someone other than the academic adviser; related to undergraduate issues rather than graduate dissertations; were discussions of the merits of a PhD by 'publication' instead of 'by thesis'; were not published in a peer-reviewed journal; or were not in English. The relationship between adviser and student changes as the student becomes a graduate, and new roles for the student and adviser need to be negotiated. Students need to realise that writing a paper from a thesis is usually going to be more difficult than they anticipate, but the application of strategies discussed in this paper should make the task manageable. Furthermore, universities might wish to consider alternatives in which published papers emerge before the examination of a thesis, such as requiring students to write a paper as part of their coursework.

    The aim of this study was to analyze relative citation ratio (RCR) of top twenty Macedonian biomedical scientists with a new metric that uses citation rates to measure influence at the article level. Top twenty Macedonian biomedical scientists were identified by GoPubMed on the base of the number of deposited abstracts in PubMed, corrected with the data from previously published paper, and completed with the Macedonian biomedical scientists working in countries outside the Republic of Macedonia, but born or previously worked in the country. iCite was used as a tool to access a dashboard of bibliometrics for papers associated with a portfolio. The biggest number of top twenty Macedonian biomedical scientists has RCR lower than one. Only four Macedonian biomedical scientists have bigger RCR in comparison with those in PubMed. The most prominent RCR of 2.29 has Rosoklija G. RCR of the most influenced individual papers deposited in PubMed has shown the biggest value for the paper of Efremov D (35.19). This paper has the biggest number of authors (860). It is necessary to accept top twenty Macedonian biomedical scientists as an example of new metric that uses citation rates to measure influence at the article level, rather than qualification of the best Macedonian biomedical scientists.

    The CONSORT statement specifies the need for a balanced presentation of both benefits and harms of medical interventions in trial reports. However, invitations to screening and newspaper articles often emphasize benefits and downplay or omit harms, and it is known that scientific articles can be influenced by conflicts of interest. We wanted to determine if a similar imbalance occurs in scientific articles on mammography screening and if it is related to author affiliation. We searched PubMed in April 2005 for articles on mammography screening that mentioned a benefit or a harm and that were published in 2004 in English. Data extraction was performed by three independent investigators, two unblinded and one blinded for article contents, and author names and affiliation, as appropriate. The extracted data were compared and discrepancies resolved by two investigators in a combined analysis. We defined three groups of authors: (1) authors in specialties unrelated to mammography screening, (2) authors in screening-affiliated specialties (radiology or breast cancer surgery) who were not working with screening, or authors funded by cancer charities, and (3) authors (at least one) working directly with mammography screening programmes. We used a data extraction sheet with 17 items described as important benefits and harms in the 2002 WHO/IARC-report on breast cancer screening. We identified 854 articles, and 143 were eligible for the study. Most were original research. Benefits were mentioned more often than harms (96% vs 62%, P < 0.001). Fifty-five (38%) articles mentioned only benefits, whereas seven (5%) mentioned only harms (P < 0.001). Overdiagnosis was mentioned in 35 articles (24%), but was more often downplayed or rejected in articles that had authors working with screening, (6/15; 40%) compared with authors affiliated by specialty or funding (1/6; 17%), or authors unrelated with screening (1/14; 7%) (P = 0.03). Benefits in terms of reduced breast cancer mortality

    To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature. Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important. A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed. It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.

    The set of references that typically appear toward the end of journal articles is sometimes, though not always, a field in bibliographic (citation) databases. But even if references do not constitute such a field, they can be useful as a preprocessing step in the automated extraction of other bibliographic data from articles, as well as in computer-assisted indexing of articles. Automation in data extraction and indexing to minimize human labor is key to the affordable creation and maintenance of large bibliographic databases. Extracting the components of references, such as author names, article title, journal name, publication date and other entities, is therefore a valuable and sometimes necessary task. This paper describes a two-step process using statistical machine learning algorithms, to first locate the references in HTML medical articles and then to parse them. Reference locating identifies the reference section in an article and then decomposes it into individual references. We formulate this step as a two-class classification problem based on text and geometric features. An evaluation conducted on 500 articles drawn from 100 medical journals achieves near-perfect precision and recall rates for locating references. Reference parsing identifies the components of each reference. For this second step, we implement and compare two algorithms. One relies on sequence statistics and trains a Conditional Random Field. The other focuses on local feature statistics and trains a Support Vector Machine to classify each individual word, followed by a search algorithm that systematically corrects low confidence labels if the label sequence violates a set of predefined rules. The overall performance of these two reference-parsing algorithms is about the same: above 99% accuracy at the word level, and over 97% accuracy at the chunk level. PMID:20640222

    2017-12-01

    To conduct an empirical investigation using qualitative techniques of the way dentists engage in the process of reading a technique-oriented journal article and what they pay attention to in the process. Grounded theory was used to identify how dentists read an article describing the fabrication of an interim prosthesis in the esthetic zone. Twenty-one experienced practitioners were videotaped, and their verbatim reflections were coded. The sequence of attending to various features of the paper was noted. Ninety-five percent of readers voiced specific, multiple attempts to identify or refine the main purpose of the article as they processed the material. All readers engaged in various activities to navigate through the article, including skipping and backtracking, and none "read" the article straight through. All readers also made repeated observations about the relevance of the technique to their personal practice situation. Eighty percent used some form of "distancing," whereby the content and value of the article were accepted, but the reader reserved the privilege of not being bound by the results because of technical, sponsorship, or methodological issues that "might be present." The quality of photographs was accepted as a proxy for the quality of technical work performed. Dentists actively customized the reading of a journal article that described a technical procedure. They imposed a non-linear structure for absorbing information and a standard of personal relevance, and, while accepting the results, created reasons for not necessarily having to accept them as applicable. The approach clinicians use in reading a procedural article may be different from the structure writers use in preparing a paper. © 2016 by the American College of Prosthodontists.

    Stroke is a disastrous disease and a major health burden worldwide, especially in Korea. Hemorrhagic stroke (HS) accounts for approximately 20% of all the types of strokes. It is important to be able to evaluate stroke diagnoses and evolving treatments. We aimed to identify the top-100 cited articles and assess a paradigm shift that occurred in the field of HS. We searched all articles that had been cited more than 100 times using the Web of Science citation search tool during January 2016. Among a total of 2,651 articles, we identified the top-100 cited articles on HS. The number of citations for the articles analyzed in this study ranged from 1,746 to 211, and the number of annual citations ranged from 125.6 to 5.5. Most of the articles that were published in Stroke (35%) and Journal of Neurosurgery (22%), originated in the United States (n = 56), were original articles (64%), and dealt with the natural history or etiology (n = 37) and vasospasm in subarachnoid hemorrhage (n = 8). We analyzed the top-100 cited articles in the field of HS based on citation rates. The results provide a unique perspective on historical and academic developments in this field. © 2017 S.

    The Centers for Disease Control and Prevention (CDC) conducts research on legal epidemiology, the scientific study of law as a factor in the cause, distribution, and prevention of disease. This study describes a scan of articles written by CDC staff members to characterize the frequency and key features of legal epidemiology articles and their distribution across CDC departments and divisions. CDC librarians searched an internal repository for journal articles by CDC staff published from January 1, 2011, to May 31, 2015. Researchers reviewed and coded the abstracts to produce data on key features of the articles. Researchers identified 158 CDC-authored legal epidemiology articles published in 83 journals, most frequently in Preventing Chronic Disease (14 publications), Journal of Public Health Management Practice (10 publications), and Morbidity and Mortality Weekly Report (9 publications). Most articles concerned the use and impact of law as a deliberate tool of intervention. Thirteen articles addressed the legal infrastructure of public health, and 3 assessed the incidental or unintended effects of nonhealth laws. CDC-authored articles encompassed policy making, implementation, and impact. Literature reviews and studies mapping laws across multiple jurisdictions constituted one-quarter of all publications. Studies addressed laws at the international, national, state, local, and organizational levels. Results of the scan can be used to identify opportunities for the agency to better support research, professional development, networking, publication, and tracking of publication in this emerging field.

    The purpose of this study was to identify and characterize the 100 top-cited articles in pulmonary imaging. From the database of Journal Citation Reports, 274 journals whose scope included pulmonary imaging were selected. The Web of Science search tools were then used to identify the 100 top-cited articles in the subject of pulmonary imaging published in these journals. The parameters used to analyze the characteristics of the 100 top-cited articles were journal (including subject category and impact factor), publication year, number of citations and annual citations, department and institution of authors, country of origin, article type, imaging technique, and topic. The 100 top-cited articles in pulmonary imaging were published between 1953 and 2012, with 43 published between 2000 and 2009. Citations ranged from 199 to 1447, and annual citations ranged from 5.1 to 314. The majority of articles were published in radiology or imaging journals (n=64), originated in the United States (n=49), were original articles (n=87), used computed tomography (n=66), and were based on the topic of pulmonary thromboembolism (n=18). Department of Radiology, Mayo Clinic (n=7), and Department of Radiology, University of British Columbia and Vancouver General Hospital (n=7), were the leading institutions, and Müller NL (n=11) was the most prolific author. Our study lists the 100 top-cited articles in pulmonary imaging, provides an insight into historical developments, and allows for recognition of advances in this field.

    2006-01-01

    Background Biomedical literature, e.g., MEDLINE, contains a wealth of knowledge regarding functions of proteins. Major recurring biological concepts within such text corpora represent the domains of this body of knowledge. The goal of this research is to identify the major biological topics/concepts from a corpus of protein-related MEDLINE© titles and abstracts by applying a probabilistic topic model. Results The latent Dirichlet allocation (LDA) model was applied to the corpus. Based on the Bayesian model selection, 300 major topics were extracted from the corpus. The majority of identified topics/concepts was found to be semantically coherent and most represented biological objects or concepts. The identified topics/concepts were further mapped to the controlled vocabulary of the Gene Ontology (GO) terms based on mutual information. Conclusion The major and recurring biological concepts within a collection of MEDLINE documents can be extracted by the LDA model. The identified topics/concepts provide parsimonious and semantically-enriched representation of the texts in a semantic space with reduced dimensionality and can be used to index text. PMID:16466569

  12. Predicting clicks of PubMed articles

    2013-01-01

    Predicting the popularity or access usage of an article has the potential to improve the quality of PubMed searches. We can model the click trend of each article as its access changes over time by mining the PubMed query logs, which contain the previous access history for all articles. In this article, we examine the access patterns produced by PubMed users in two years (July 2009 to July 2011). We explore the time series of accesses for each article in the query logs, model the trends with regression approaches, and subsequently use the models for prediction. We show that the click trends of PubMed articles are best fitted with a log-normal regression model. This model allows the number of accesses an article receives and the time since it first becomes available in PubMed to be related via quadratic and logistic functions, with the model parameters to be estimated via maximum likelihood. Our experiments predicting the number of accesses for an article based on its past usage demonstrate that the mean absolute error and mean absolute percentage error of our model are 4.0% and 8.1% lower than the power-law regression model, respectively. The log-normal distribution is also shown to perform significantly better than a previous prediction method based on a human memory theory in cognitive science. This work warrants further investigation on the utility of such a log-normal regression approach towards improving information access in PubMed. PMID:24551386

All the articles were collected from the China National Knowledge Infrastructure (CNKI, January 1, 1943 to December 25, 2016), Web of Science (January 1, 1950 to December 25, 2016), WANFANG Database (January 1, 1998 to December 25, 2016). The top-cited articles were selected and analyzed with regard to publication year, number of citations, journals, authors, country or region, institution, title, type and subject. One hundred and two articles were included, 43 Chinese articles and 59 English articles, cited between 146 and 505 times, and the average number of citation was 222. Of the 10 articles cited in the top 10, China and the United States had 4 articles respectively. These articles appeared in 44 journals, 24 articles in Chinese Acupuncture & Moxibustion , followed by 8 articles in Pain . All the articles belonged to 9 countries and regions, 47 articles from mainland China and 21 articles from the United State. Of the 14 institutes whose article number ranked at top 10, Tianjing University of TCM had 8 articles. The first authors published most papers were professor HAN Jisheng and Cherkin DC, each of whom had 4 articles. All the articles were categorized into basic science article (n=27), clinical research (n=33) and literature study (n=42). The main topics were pain diseases and brain impairment. This analysis of high cited articles reveals academic trends and directions of acupuncture and moxibustion. Acupuncture and moxibustion are more and more recognized by mainstream medicine in the world, but the academic dominance of China has been increasingly challenged by the United States, Germany and so on.

    Objectives To investigate barriers related to prenatal care utilization among women. Methods Data was collected in both English and Persian databases. English databases included: the International Medical Sciences, Medline, Web of Science, Scopus, Google Scholar. The Persian databases included: the Iranmedex, the State Inpatient Databases (SID) with the use of related keywords, and on the basis of inclusion-exclusion criteria. The keywords included are barrier, prenatal care, women, access, and preventive factors. OR and AND were Boolean operators. After the study, articles were summarized, unrelated articles were rejected, and related articles were identified. Inclusion criteria were all published articles from 1990 to 2015, written in English and Persian languages. The titles and abstracts are related, and addressed all subjects about barriers related to prenatal care utilization. At the end, all duplicated articles were excluded. There were no restrictions for exclusion or inclusion of articles. Exclusion criteria were failure in reporting in studies, case studies, and lack of access to the full text. Results After searching various databases, 112 related articles were included. After reviewing articles’ titles, 67 unrelated articles and abstracts were rejected, 45 articles were evaluated, 20 of them were duplicated. Then, the qualities of 25 articles were analyzed. Therefore, 5 articles were excluded due to not mentioning the sample size, mismatches between method and data, or results. Total of 20 articles were selected for final analysis. Prenatal care utilization barrier can be divided into various domains such as individual barriers, financial barriers, organizational barriers, social, and cultural barriers. Conclusion To increase prenatal care coverage, it is necessary to pay attention to all domains, especially individual and financial barriers.

    The paper analyses the development of the total number of journal articles indexed in the Medline database published by authors affiliated to Denmark 1989-1998 in medicine compared to the development in the European Union during the same period. The publication analysis is then compared to the citation impact of articles published in the central journals indexed in Science Citation Index (ISI) 1987-1996 through use of the National Science Indicators (NIS, ISI) database. The total number of Danish journal articles has remained relatively constant compared to a 50% increase in the EU as a whole. The number of Danish articles published in central journals, however, has increased by 20% (compared to 27% for the EU) and the number of citations obtained by these articles by 58% (compared to 66% for the EU) in the 1987-1996 period. By population, Denmark ranked third in total number of articles in 1998. In conclusion, Denmark is very active in medical research but neither the quantity nor the quality of Danish medical research has increased at the same rate as the EU average.

    2015-01-01

    Since social media started getting more attention from users on the Internet, social media has been one of the most important information source in the world. Especially, with the increasing popularity of social media, data posted on social media sites are rapidly becoming collective intelligence, which is a term used to refer to new media that is displacing traditional media. In this paper, we focus on geotagged tweets on the Twitter site. These geotagged tweets are referred to as georeferenced documents because they include not only a short text message, but also the documents' posting time and location. Many researchers have been tackling the development of new data mining techniques for georeferenced documents to identify and analyze emergency topics, such as natural disasters, weather, diseases, and other incidents. In particular, the utilization of geotagged tweets to identify and analyze natural disasters has received much attention from administrative agencies recently because some case studies have achieved compelling results. In this paper, we propose a novel real-time analysis application for identifying bursty local areas related to emergency topics. The aim of our new application is to provide new platforms that can identify and analyze the localities of emergency topics. The proposed application is composed of three core computational intelligence techniques: the Naive Bayes classifier technique, the spatiotemporal clustering technique, and the burst detection technique. Moreover, we have implemented two types of application interface: a Web application interface and an android application interface. To evaluate the proposed application, we have implemented a real-time weather observation system embedded the proposed application. we used actual crawling geotagged tweets posted on the Twitter site. The weather observation system successfully detected bursty local areas related to observed emergency weather topics.

    The number of citations that a research paper receives can be used as a measure of its scientific impact. The objective of this study was to identify and to examine the characteristics of top 100 cited articles in the field of Medical Informatics based on data acquired from the Thomson Reuters' Web of Science (WOS) in October, 2016. The data was collected using two procedures: first we included articles published in the 24 journals listed in the "Medical Informatics" category; second, we retrieved articles using the key words: "informatics", "medical informatics", "biomedical informatics", "clinical informatics" and "health informatics". After removing duplicate records, articles were ranked by the number of citations they received. When the 100 top cited articles had been identified, we collected the following information for each record: all WOS database citations, year of publication, journal, author names, authors' affiliation, country of origin and topics indexed for each record. Citations for the top 100 articles ranged from 346 to 7875, and citations per year ranged from 11.12 to 525. The majority of articles were published in the 2000s (n=43) and 1990s (n=38). Articles were published across 10 journals, most commonly Statistics in medicine (n=71) and Medical decision making (n=28). The articles had an average of 2.47 authors. Statistics and biostatistics modeling was the most common topic (n=71), followed by artificial intelligence (n=12), and medical errors (n=3), other topics included data mining, diagnosis, bioinformatics, information retrieval, and medical imaging. Our bibliometric analysis illustrated a historical perspective on the progress of scientific research on Medical Informatics. Moreover, the findings of the current study provide an insight on the frequency of citations for top cited articles published in Medical Informatics as well as quality of the works, journals, and the trends steering Medical Informatics.

    PubMed

    Daldrup-Link, Heike E

    2018-01-01

    An explosion of scientific publications over the last decades has increased the need for review articles: Carefully crafted scientific review articles can provide the novice reader with an overview of a new subject and provide the expert with a synthesis of scientific evidence, proof of reproducibility of published data and pooled estimates of common truth through meta-analyses. Unfortunately, while there are ample presentations and published guidelines for the preparation of scientific articles available, detailed information about how to properly prepare scientific review articles is relatively scarce. This perspective summarizes possible mistakes that can lead to misinformation in scientific review articles with the goal to help authors to improve the scientific contribution of their review article and thereby, increase the respective value of these articles for the scientific community.

    2009-10-01

    In the past 5 years the Icelandic Medical Journal has undergone many changes during a period of flourishing research in Iceland. The process of reviewing and editing scientific articles has been revised since the Journal joined the Medline database in 2005 and the proportion of rejected articles has risen. New columns have been launched covering medical history, professionalism, ethics and hobbies of the medical profession. We categorized all scientific articles from the period 2004-2008, that is research articles, review articles, case reports and clinical guidelines, according to types of articles and to which medical speciality or subspeciality the publication should belong. The number of scientific articles rose during the period but the number of research articles remained around 20 most years during the period. The relative proportion of research articles therefore fell whereas the number and proportion of review articles and case reports increased. Clinical guidelines ceased to appear in the Journal. The contribution of individual specialities to the Journal varied widely. Researchers amongst doctors and related professions need be encouraged to submit scientific articles to the Journal. The publication of scientific articles in English in the web-based form of the Journal may prove to be stimulating in this regard for Icelandic doctors abroad as well as for some researchers in Iceland.

    Bibliometric analysis is the application of statistical methods to analyze quantitative data about scientific publications. It can evaluate research performance, author productivity, and manuscript impact. To the best of our knowledge, no bibliometric analysis has focused on cardiac computed tomography (CT). The purpose of this paper was to compile a list of the 100 most-cited articles related to cardiac CT literature using Scopus and Web of Science (WOS). A list of the 100 most-cited articles was compiled by order of citation frequency, as well a list of the top 10 most-cited guideline and review articles and the 20 most-cited articles of the years 2014-2015. The database of 100 most-cited articles was analyzed to identify characteristics of highly cited publications. For each manuscript, the number of authors, study design, size of patient cohort and departmental affiliations were cataloged. The 100 most-cited articles were published from 1990 to 2012, with the majority (53) published between 2005 and 2009. The total number of citations varied from 3354 to 196, and the number of citations per year varied from 9.5 to 129.0 with a median and mean of 30.9 and 38.7, respectively. The majority of publications had a study patients sample size of 200 patients or less. The USA and Germany were the nations with the highest number of frequently cited publications. This bibliometric analysis provides insights on the most-cited articles published on the subject of cardiac CT and calcium volume, thus helping to characterize the field and guide future research.

    2016-08-01

    Endoscopic endonasal skull base surgery has become widely accepted in neurosurgery and otolaryngology over the last 15 years. However, there has yet to be a formal curation of the most impactful articles for an introductory curriculum to its technical evolution. The Science Citation Index Expanded was used to generate a citation rank list (October 2015) on articles relevant to endoscopic skull base surgery. The top 35 cited articles overall, as well as the top 15 since 2009, were identified. Journal, year, author, study population, article format, and level of evidence were compiled. Additional surgeon experts were polled and made recommendations for significant contributions to the literature. The top 35 publications ranged from 98 to 467 citations and were published in 10 different journals. Four articles had more than 250 citations. A period of frequent contribution occurred between 2005 and 2009, when 21/35 reports were published. 18/35 articles were case series, and 13/35 were technical reports. There were 11/35 articles focused primarily on pituitary surgery and 10/35 on extrasellar lesions. The top 15 articles since 2009 had 8/15 articles focused on extrasellar lesions. Polled surgeons consistently identified the most prominently cited articles, and their recommendations drew attention to cerebrospinal fluid leak as well as extrasellar management. Identification of the most cited works within endoscopic endonasal skull base surgery shows greater anatomic access and safety over the last 2 decades. These articles can serve as an educational tool for novices or midlevel practitioners wishing to obtain a greater understanding of the field. Copyright © 2016 Elsevier Inc. All rights reserved.

    2016-01-01

    AIM: The aim of this study was to analyze relative citation ratio (RCR) of top twenty Macedonian biomedical scientists with a new metric that uses citation rates to measure influence at the article level. MATERIAL AND METHODS: Top twenty Macedonian biomedical scientists were identified by GoPubMed on the base of the number of deposited abstracts in PubMed, corrected with the data from previously published paper, and completed with the Macedonian biomedical scientists working in countries outside the Republic of Macedonia, but born or previously worked in the country. iCite was used as a tool to access a dashboard of bibliometrics for papers associated with a portfolio. RESULTS: The biggest number of top twenty Macedonian biomedical scientists has RCR lower than one. Only four Macedonian biomedical scientists have bigger RCR in comparison with those in PubMed. The most prominent RCR of 2.29 has Rosoklija G. RCR of the most influenced individual papers deposited in PubMed has shown the biggest value for the paper of Efremov D (35.19). This paper has the biggest number of authors (860). CONCLUSION: It is necessary to accept top twenty Macedonian biomedical scientists as an example of new metric that uses citation rates to measure influence at the article level, rather than qualification of the best Macedonian biomedical scientists.

  14. Altmetric: Top 50 dental articles in 2014.

    PubMed

    Kolahi, J; Khazaei, S

    2016-06-10

    Introduction Altmetrics is a new and emerging scholarly tool that measures online attention surrounding journal articles. Altmetric data resources include: policy documents, news outlets, blogs, online reference managers (eg Mendeley and CiteULike), post-publication peer-review forums (eg PubPeer and Publons), social media (eg Twitter, Facebook, Weibo, Google(+), Pinterest, Reddit), Wikipedia, sites running Stack Exchange (Q&A), and reviews on F1000 and YouTube.Methods To identify the top 50 dental articles in 2014, PubMed was searched using the following query "("2014/1/1"[PDAT]:"2014/12/31"[PDAT]) and jsubsetd[text]" in December, 2015. Consequently, all PubMed records were extracted and sent to Altmetric LLP (London, UK) as a CSV file for examination. Data were analysed by Microsoft Office Excel 2010 using descriptive statistics and charts.Results Using PubMed searches,15,132 dental articles were found in 2014. The mean Altmetric score of 50 top dental articles in 2014 was 69.5 ± 73.3 (95% CI: -74.14 to 213.14). The British Dental Journal (48%) and Journal of Dental Research (16%) had the maximum number of top articles. Twitter (67.13%), Mendeley (15.89%) and news outlets (10.92%) were the most popular altmetric data resources.Discussion Altmetrics are intended to supplement bibliometrics, not replace them. Altmetrics is a fresh and emerging arena for the dental research community. We believe that dental clinical practitioners, research scientists, research directors and journal editors must pay more attention to altmetrics as a new and rapid tool to measure the social impact of scholarly articles.

  15. Which articles and which topics in the forensic sciences are most highly cited?

    Forensic science is a multidisciplinary field, which covers many branches of the pure, the applied and the biomedical sciences. Writing-up and publishing research findings helps to enhance the reputation of the investigators and the laboratories where the work was done. The number of times an article is cited in the reference lists of other articles is generally accepted as a mark of distinction. Indeed, citation analysis has become widely used in research assessment of individual scientists, university departments and entire nations. This article concerns the most highly cited papers published in the Journal of Forensic Sciences (JFS) between 1956 and 2005. These were identified with the help of Web-of-Science, which is the on-line version of Science Citation Index, produced by Thomson Institute for Scientific Information (Thomson ISI) with head offices in Philadelphia, USA. This database tracks, among other things, the annual citation records of articles published in several thousand scientific journals worldwide. Those JFS articles accumulating 50 or more citations were identified and rank-ordered according to the total number of citations. These articles were also evaluated according to the name of first author, the subject category of the article, the country of origin and the pattern of co-authorship. This search strategy located 46 articles cited between 50 and 292 times since they first appeared in print. The most highly cited paper by far was by Kasai, Nakamura and White (USA and Japan) concerning DNA profiling and the application of the polymerase chain reaction (PCR) in forensic science. Some forensic scientists appeared as first author on two to three highly cited articles, namely Wetli (USA), Budowle (USA) and Comey (USA). When the highly cited articles were sub-divided into subject category, 15 were identified as coming from toxicology, closely followed by criminalistics (14 articles), pathology (nine articles), physical anthropology (five articles

    In this study, we present an analysis of data citation practices in full text research articles and their corresponding supplementary data files, made available in the Open Access set of articles from Europe PubMed Central. Our aim is to investigate whether supplementary data files should be considered as a source of information for integrating the literature with biomolecular databases. Using text-mining methods to identify and extract a variety of core biological database accession numbers, we found that the supplemental data files contain many more database citations than the body of the article, and that those citations often take the form of a relatively small number of articles citing large collections of accession numbers in text-based files. Moreover, citation of value-added databases derived from submission databases (such as Pfam, UniProt or Ensembl) is common, demonstrating the reuse of these resources as datasets in themselves. All the database accession numbers extracted from the supplementary data are publicly accessible from http://dx.doi.org/10.5281/zenodo.11771. Our study suggests that supplementary data should be considered when linking articles with data, in curation pipelines, and in information retrieval tasks in order to make full use of the entire research article. These observations highlight the need to improve the management of supplemental data in general, in order to make this information more discoverable and useful.

    2011-01-01

    Every article on stimulus equivalence or derived stimulus relations published in the Journal of Applied Behavior Analysis was evaluated in terms of characteristics that are relevant to the development of applied technologies: the type of participants, settings, procedure (automated vs. tabletop), stimuli, and stimulus sensory modality; types of relations targeted and emergent skills demonstrated by participants; and presence versus absence of evaluation of generalization and maintenance. In most respects, published reports suggested the possibility of applied technologies but left the difficult work of technology development to future investigations, suggestions for which are provided.

  2. Short-time windowed covariance: A metric for identifying non-stationary, event-related covariant cortical sites

    Background Electrocorticography (ECoG) signals can provide high spatio-temporal resolution and high signal to noise ratio recordings of local neural activity from the surface of the brain. Previous studies have shown that broad-band, spatially focal, high-frequency increases in ECoG signals are highly correlated with movement and other cognitive tasks and can be volitionally modulated. However, significant additional information may be present in inter-electrode interactions, but adding additional higher order inter-electrode interactions can be impractical from a computational aspect, if not impossible. New method In this paper we present a new method of calculating high frequency interactions between electrodes called Short-Time Windowed Covariance (STWC) that builds on mathematical techniques currently used in neural signal analysis, along with an implementation that accelerates the algorithm by orders of magnitude by leveraging commodity, off-the-shelf graphics processing unit (GPU) hardware. Results Using the hardware-accelerated implementation of STWC, we identify many types of event-related inter-electrode interactions from human ECoG recordings on global and local scales that have not been identified by previous methods. Unique temporal patterns are observed for digit flexion in both low- (10 mm spacing) and high-resolution (3 mm spacing) electrode arrays. Comparison with existing methods Covariance is a commonly used metric for identifying correlated signals, but the standard covariance calculations do not allow for temporally varying covariance. In contrast STWC allows and identifies event-driven changes in covariance without identifying spurious noise correlations. Conclusions: STWC can be used to identify event-related neural interactions whose high computational load is well suited to GPU capabilities. PMID:24211499

    This article presents a review of the medical literature published between 1994 and 2014 with the use of the PubMed database concerning quality-of-life instruments for head and neck cancer patients used to assess general well-being of patients with laryngeal cancer. The PubMed database was searched for articles containing the keywords "quality of life", "laryngeal neoplasm" and "questionnaires". The resulting articles were reviewed and analyzed. After the identification of questionnaires, an additional search was performed. The articles and questionnaires were described and analyzed. In 43 articles, the authors used questionnaires specific to the head and neck regions in order to assess the quality of life in patients with laryngeal cancer. Four different questionnaires were identified. The European Organization for Research and Treatment of Cancer (EORTC) questionnaire is most commonly used to assess the quality of life in patients with laryngeal cancer. Questionnaires are generally used in order to select from a range of different treatment methods. There are a few head and neck cancer-related quality-of-life instruments which are widely used to assess the quality of life in patients with laryngeal cancer, but they are not dedicated to that region of the body. Today, there is much more attention paid to the quality of life; therefore, there is a real need to develop specific scales for different types of cancer.

    The not criminally responsible on account of mental disorder (NCRMD) designation remains widely misunderstood by the public. Such misunderstandings may also be reflected in the media. As such, the aim of this study is to conduct a preliminary examination of the tone and content of recent Canadian newspaper articles where NCRMD is a major theme, comparing these to generic articles about mental illness. Articles about mental illness were gathered from major Canadian newspapers. These were then divided into two categories: 1) articles where NCRMD was a major theme and 2) articles where NCRMD was not a major theme. Articles were then coded for the presence or absence of 1) a negative tone, 2) stigmatising tone/content, 3) recovery/rehabilitation as a theme, and 4) shortage of resources/poor quality of care as a theme. The retrieval strategy resulted in 940 articles. Fourteen percent ( n = 131) of all articles had NCRMD as a major theme. In comparison to generic articles about mental illness, articles with NCRMD as a major theme were significantly more likely to have a negative tone ( P < 0.001) and stigmatising tone/content ( P < 0.001) and significantly less likely to have recovery/rehabilitation ( P < 0.001) or shortage of resources/poor quality of care as a theme ( P < 0.001). Articles with NCRMD as a theme were overwhelmingly negative and almost never focused on recovery or rehabilitation, in stark comparison to generic articles about mental illness.

    What is good bioethics? Addressing this question is key for reinforcing and developing the field. In particular, a discussion of potential quality criteria can heighten awareness and contribute to the quality of bioethics publications. Accordingly, the objective of this article is threefold: first, we want to identify a set of criteria for quality in bioethics. Second, we want to illustrate the added value of a novel method: in-depth analysis of a single article with the aim of deriving quality criteria. The third and ultimate goal is to stimulate a broad and vivid debate on goodness in bioethics. An initial literature search reveals a range of diverse quality criteria. In order to expand on the realm of such quality criteria, we perform an in-depth analysis of an article that is acclaimed for being exemplary. The analysis results in eleven specific quality criteria for good bioethics in three categories: argumentative, empirical, and dialectic. Although we do not claim that the identified criteria are universal or absolute, we argue that they are fruitful for fueling a continuous constitutive debate on what is "good bioethics." Identifying, debating, refining, and applying such criteria is an important part of defining and improving bioethics.

    2017-10-01

    Recent years have seen numerous efforts and resources devoted to the development of open access (OA), but the current OA situation of the oncology literature remains unknown. We conducted this cross-sectional study to determine the current share and provision methods of OA in the field of oncology, identify predictors of OA status (OA versus non-OA), and study the association between OA and citation counts. PubMed was searched for oncology-related, peer-reviewed journal articles published in December 2014. Google, Google Scholar, PubMed, ResearchGate, OpenDOAR and OAIster were manually checked to assess the OA status of each included article. Citation data were extracted from Web of Science, Scopus and Google Scholar. Descriptive statistics were used to summarize the OA proportion (primary outcome) and OA provision methods. Multivariable logistic regression and multilevel generalized linear model analyses were performed to study predictors of OA status and the association between OA and citation counts, respectively. In a random sample of 1000 articles, 912 were deemed eligible and therefore included. Of these, the full-texts of 530 articles (58.1%; 95% CI: 54.9-61.3) were freely available online: 314 (34.4%) were available from publishers ('Gold road' to OA), 424 (46.5%) were available via self-archiving ('Green road' to OA). According to multivariable regression analyses, impact factor, publisher type, language, research type, number of authors, continent of origin, and country income were significant predictors of articles' OA status; OA articles received a citation rate 1.24 times the incidence rate for non-OA articles (95% CI: 1.05-1.47; P = 0.012). Based on our sample, in the field of oncology, 42% of recent journal articles are behind the pay-wall (non-OA) 1 year after publication; the 'Green road' of providing OA is more common than the 'Gold road'; OA is associated with higher citation counts. © The Author 2017.

    To assess what is lost if only one literature database is searched for articles relevant to injury prevention and safety promotion (IPSP) topics. Serial textword (keyword, free-text) searches using multiple synonym terms for five key IPSP topics (bicycle-related brain injuries, ethanol-impaired driving, house fires, road rage, and suicidal behaviors among adolescents) were conducted in four of the bibliographic databases that are most used by IPSP professionals: EMBASE, MEDLINE, PsycINFO, and Web of Science. Through a systematic procedure, an inventory of articles on each topic in each database was conducted to identify the total unduplicated count of all articles on each topic, the number of articles unique to each database, and the articles available if only one database is searched. No single database included all of the relevant articles on any topic, and the database with the broadest coverage differed by topic. A search of only one literature database will return 16.7-81.5% (median 43.4%) of the available articles on any of five key IPSP topics. Each database contributed unique articles to the total bibliography for each topic. A literature search performed in only one database will, on average, lead to a loss of more than half of the available literature on a topic.

  13. Measuring the Interestingness of Articles in a Limited User Environment Prospectus

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Pon, Raymond K.

    2007-04-18

    Search engines, such as Google, assign scores to news articles based on their relevancy to a query. However, not all relevant articles for the query may be interesting to a user. For example, if the article is old or yields little new information, the article would be uninteresting. Relevancy scores do not take into account what makes an article interesting, which would vary from user to user. Although methods such as collaborative filtering have been shown to be effective in recommendation systems, in a limited user environment there are not enough users that would make collaborative filtering effective. I presentmore » a general framework for defining and measuring the ''interestingness'' of articles, called iScore, incorporating user-feedback including tracking multiple topics of interest as well as finding interesting entities or phrases in a complex relationship network. I propose and have shown the validity of the following: 1. Filtering based on only topic relevancy is insufficient for identifying interesting articles. 2. No single feature can characterize the interestingness of an article for a user. It is the combination of multiple features that yields higher quality results. For each user, these features have different degrees of usefulness for predicting interestingness. 3. Through user-feedback, a classifier can combine features to predict interestingness for the user. 4. Current evaluation corpora, such as TREC, do not capture all aspects of personalized news filtering systems necessary for system evaluation. 5. Focusing on only specific evolving user interests instead of all topics allows for more efficient resource utilization while yielding high quality recommendation results. 6. Multiple profile vectors yield significantly better results than traditional methods, such as the Rocchio algorithm, for identifying interesting articles. Additionally, the addition of tracking multiple topics as a new feature in iScore, can improve i

    Schemas to identify bleeding-related hospitalizations in claims data differ in billing codes used and coding positions allowed. We assessed agreement across bleeding-related hospitalization coding schemas for claims analyses of nonvalvular atrial fibrillation (NVAF) patients on oral anticoagulation (OAC). We hypothesized that prior coding schemas used to identify bleeding-related hospitalizations in claim database studies would provide varying levels of agreement in incidence rates. Within MarketScan data, we identified adults, newly started on OAC for NVAF from January 2012 to June 2015. Billing code schemas developed by Cunningham et al., the US Food and Drug Administration (FDA) Mini-Sentinel program, and Yao et al. were used to identify bleeding-related hospitalizations as a surrogate for major bleeding. Bleeds were subcategorized as intracranial hemorrhage (ICH), gastrointestinal (GI), or other. Schema agreement was assessed by comparing incidence, rates of events/100 person-years (PYs), and Cohen's kappa statistic. We identified 151 738 new-users of OAC with NVAF (CHA2DS2-VASc score = 3, [interquartile range = 2-4] and median HAS-BLED score = 3 [interquartile range = 2-3]). The Cunningham, FDA Mini-Sentinel, and Yao schemas identified any bleeding-related hospitalizations in 1.87% (95% confidence interval [CI]: 1.81-1.94), 2.65% (95% CI: 2.57-2.74), and 4.66% (95% CI: 4.55-4.76) of patients (corresponding rates = 3.45, 4.90, and 8.65 events/100 PYs). Kappa agreement across schemas was weak-to-moderate (κ = 0.47-0.66) for any bleeding hospitalization. Near-perfect agreement (κ = 0.99) was observed with the FDA Mini-Sentinel and Yao schemas for ICH-related hospitalizations, but agreement was weak when comparing Cunningham to FDA Mini-Sentinel or Yao (κ = 0.52-0.53). FDA Mini-Sentinel and Yao agreement was moderate (κ = 0.62) for GI bleeding, but agreement was weak when comparing Cunningham to FDA Mini-Sentinel or Yao (κ

    Analysis of the number of citations within a given specialty provides information on the classic publications of that specialty. The goals of this study were to identify the 50 most cited articles on rotator cuff repair and to analyze various characteristics of these articles. The ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was used to conduct a search for the term rotator cuff repair. The 50 most cited articles were retrieved, and the following objective characteristics of each article were recorded: number of times cited, citation density, journal, country of origin, and language. The following subjective characteristics of each article were also recorded: article type (clinical vs basic science), article subtype, and level of evidence for clinical articles. Of the 50 most cited articles on rotator cuff repair, the number of citations ranged from 138 to 677 (mean, 232±133 citations) and citation density ranged from 3.8 to 53.5 citations per year (mean, 16.9±9.2 citations per year). The articles were published between 1974 and 2011, with most of the articles published in the 2000s (29 articles), followed by the 1990s (16 articles). The articles originated from 8 countries, with the United States accounting for 30 articles (60%). Overall, 66% of the articles were clinical and 34% were basic science. The most common article subtype was the clinical case series (48%). Of the 33 clinical articles, 24 (73%) were level IV. Among the 50 most cited articles on rotator cuff repair, the case series was the most common article subtype, showing the effect that publication of preliminary outcomes and new surgical techniques has had on surgeons performing rotator cuff repair.

    Widely varying reading lists for general psychiatry residents were obtained from 140 three-year approved training programs. The material recommended for reading was listed on index cards, and the number of programs recommending each item was posted on the cards. Approximately 4,000 articles, 2,800 books, and 200 serials were recommended. A statistical evaluation of the book list appeared in a previous paper (3).* Part II is a similar evaluation of the article list and the limited editions and serials in which the articles appear.

    Fardi, Anastasia; Kodonas, Konstantinos; Lillis, Theodoros; Veis, Alexander

    Citation analysis is the field of bibliometrics that uses citation data to evaluate the scientific recognition and the influential performance of a research article in the scientific community. The aim of this study was to conduct a bibliometric analysis of the top-cited articles pertaining to implant dentistry, to analyze the main characteristics, and to display the most interesting topics and evolutionary trends. The 100 top-cited articles published in "Dentistry, Oral Surgery, and Medicine" journals were identified using the Science Citation Index Database. The articles were further reviewed, and basic information was collected, including the number of citations, journals, authors, publication year, study design, level of evidence, and field of study. The highly cited articles in implant dentistry were cited between 199 and 2,229 times. The majority of them were published in four major journals: Clinical Oral Implants Research, International Journal of Oral & Maxillofacial Implants, Journal of Clinical Periodontology, and Journal of Periodontology. The publication year ranged from 1981 to 2009, with 45% published in a nine-year period (2001 to 2009). Publications from the United States (29%) were the most heavily cited, followed by those from Sweden (23%) and Switzerland (17%). The University of Göteborg from Sweden produced the highest number of publications (n = 19), followed by the University of Bern in Switzerland (n = 13). There was a predominance of clinical papers (n = 42), followed by reviews (n = 25), basic science research (n = 21), and proceedings papers (n = 12). Peri-implant tissue healing and health (24%), implant success/failures (19.2%), and biomechanical topics (16.8%) were the most common fields of study. Citation analysis in the field of implant dentistry reveals interesting information about the topics and trends negotiated by researchers and elucidates which characteristics are required for a paper to attain a "classic" status.

    With limited statistical knowledge of most physicians it is not uncommon to find statistical errors in research articles. To determine the statistical methods and to assess the statistical errors in family medicine (FM) research articles that were published between 2010 and 2014. This was a cross-sectional study. All 66 FM research articles that were published over 5 years by FM authors with affiliation to Suez Canal University were screened by the researcher between May and August 2015. Types and frequencies of statistical methods were reviewed in all 66 FM articles. All 60 articles with identified inferential statistics were examined for statistical errors and deficiencies. A comprehensive 58-item checklist based on statistical guidelines was used to evaluate the statistical quality of FM articles. Inferential methods were recorded in 62/66 (93.9%) of FM articles. Advanced analyses were used in 29/66 (43.9%). Contingency tables 38/66 (57.6%), regression (logistic, linear) 26/66 (39.4%), and t-test 17/66 (25.8%) were the most commonly used inferential tests. Within 60 FM articles with identified inferential statistics, no prior sample size 19/60 (31.7%), application of wrong statistical tests 17/60 (28.3%), incomplete documentation of statistics 59/60 (98.3%), reporting P value without test statistics 32/60 (53.3%), no reporting confidence interval with effect size measures 12/60 (20.0%), use of mean (standard deviation) to describe ordinal/nonnormal data 8/60 (13.3%), and errors related to interpretation were mainly for conclusions without support by the study data 5/60 (8.3%). Inferential statistics were used in the majority of FM articles. Data analysis and reporting statistics are areas for improvement in FM research articles.

    Nasopharyngeal cancer or nasopharyngeal carcinoma (NPC) is the most common cancer originating in the nasopharynx. The factors that induce nasopharyngeal cancer are still not clear. Additional information about the chemicals or genes related to nasopharyngeal cancer will promote a better understanding of the pathogenesis of this cancer and the factors that induce it. Thus, a computational method NPC-RGCP was proposed in this study to identify the possible relevant chemicals and genes based on the presently known chemicals and genes related to nasopharyngeal cancer. To extensively utilize the functional associations between proteins and chemicals, a heterogeneous network was constructed based on interactions of proteins and chemicals. The NPC-RGCP included two stages: the searching stage and the screening stage. The former stage is for finding new possible genes and chemicals in the heterogeneous network, while the latter stage is for screening and removing false discoveries and selecting the core genes and chemicals. As a result, five putative genes, CXCR3, IRF1, CDK1, GSTP1, and CDH2, and seven putative chemicals, iron, propionic acid, dimethyl sulfoxide, isopropanol, erythrose 4-phosphate, β-D-Fructose 6-phosphate, and flavin adenine dinucleotide, were identified by NPC-RGCP. Extensive analyses provided confirmation that the putative genes and chemicals have significant associations with nasopharyngeal cancer.

    To give an overview of the behaviour and scientific contributions of the Journal of Bone and Joint Surgery American (JBJS-A) and British Volume (JBJS-B). 480 original articles published in 2009 were identified through a combined comprehensive computer and manual library search. Articles were assigned to 11 orthopaedic categories and by country, type and specialty of the institution. Possible grants and citations were analysed. USA led all countries in published articles (36,87%), followed by UK (20,62%) and South Korea (5,83%). Most studies published were performed at academic institutions (65,83 %), only 4,16% at private practices. Almost half of the articles (46,24%) were published in three categories: hip (19.16%), knee (13.75%) and trauma (13.33%). In both journals 47.15% articles had at least one funding source. A review of articles published in major journals allows to show how research in orthopaedics is distributed worldwide. This study shows that a variety of different journals is neccessary to reflect the broad spectrum of orthopaedics in depth. Level of Evidence III, Retrospective Comparative Study.

    The purpose of this study was to identify the 100 top-cited articles in the radiology of trauma, analyze the resulting database to understand factors resulting in highly cited works, and establish trends in trauma imaging. An initial database was created via a Web of Science (WOS) search of all scientific journals using the search terms "trauma" and either "radiology" or a diagnostic modality. Articles were ranked by citation count and screened by two attending radiologists plus a tiebreaker for appropriateness. The following information was collected from each article: WOS all database citations, year, journal, authors, department affiliation, study type and design, sample size, imaging modality, subspecialty, organ, and topic. Citations for the top 100 articles ranged from 82-252, and citations per year ranged from 2.6-37.2. A plurality of articles were published in the 1990s (n = 45) and 1980s (n = 31). Articles were published across 24 journals, most commonly Radiology (n = 31) and Journal of Trauma-Injury, Infection, and Critical Care (n = 28). Articles had an average of five authors and 35 % of first authors were affiliated with a department other than radiology. Forty-six articles had sample sizes of 100 or fewer. Computed tomography (CT) was the most common modality (n = 67), followed by magnetic resonance (MR; n = 22), and X-ray (XR; n = 11). Neuroradiology (n = 48) and abdominal radiology (n = 36) were the most common subspecialties. The 100 top-cited articles in the radiology of trauma are diverse. Subspecialty bibliometric analyses identify the most influential articles of a particular field, providing more implications to clinical radiologists, trainees, researchers, editors, and reviewers than radiology-wide lists.

    The number of times an article has been cited in the peer-reviewed literature is indicative of its impact on its respective medical specialty. No study has used citation analysis to determine the most influential studies pertaining to the anterior cruciate ligament (ACL). The primary aims of this study were to identify the classic works in ACL research using citation analysis and to characterize these articles to determine which types of studies have had the most influence on the field. A systematic query of ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was performed for articles pertaining to the ACL, and the 50 most-cited articles were selected for evaluation. The following characteristics were determined for each article: number of citations, citation density, journal, publication year, country of origin, language, article type, article subtype, and level of evidence. The number of citations ranged from 219 to 1073 (mean, 326), and the citation densities ranged from 4.9 to 55.6 citations per year (mean, 18.2). All articles were published in 1 of 11 journals, with the most being published in The American Journal of Sports Medicine (46%) and The Journal of Bone and Joint Surgery American (30%). The most common decades of publication were the 1990s (34%), 1980s (28%), and 2000s (26%). The majority (68%) of articles originated from the United States, and all were written in English. By article type, 42% were basic science, and 58% were clinical. Of the clinical articles, 3% were Level I, 17% were Level II, 28% were Level III, and 52% were Level IV. The articles were heterogeneous with regard to article type, article subtype, and level of evidence and tended to have the following characteristics: high-impact journal of publication, recent publication year, US origin, English language, and low level of evidence. These works represent some of the most popular scientific contributions to ACL research. This list may aid residency and fellowship

    The aim of this research is to identify the difficulties experienced by secondary school students (aged 15-16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties 'Elements of science critical reading' were identified on the basis of the 'Elements of reasoning' of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results.

    With more than 50,000 orthopaedic surgeons, China is having an increasing impact on fracture surgery research. However, the most influential Chinese articles on fracture surgery have not been determined. This study aimed to characterise the most-cited articles on fracture surgery by Chinese authors to provide insight into the fracture research in China. The Web of Science was used to search for citations of fracture surgery articles that originated in China. The 50 most-cited articles were identified. The title, number of citations, year of publication, journal, article type, level of evidence, city, institution, and authors were recorded and evaluated. The 50 top-cited papers were published between 1984 and 2012. The most prolific decade began in the year 2000. These articles received 28 to 209 citations (mean 52), were written in English, and published in 12 journals. Injury was the most popular journal, with the largest number of articles (11) on the top 50 list. The region with the largest number of published articles was Hong Kong (20), followed by Kaohsiung (8), Shanghai (8), and Taipei (7). Most were clinical studies (39), while the remaining studies were basic science articles (11). The hip was the most common topic in the clinical studies. The most popular level of evidence was IV. This list of the top 50 publications identifies the most influential Chinese fracture surgery articles for the global community. This study presents insight into the historical contributions of Chinese researchers and the fracture surgery trends in China.

    Health science findings are primarily disseminated through manuscript publications. Information subsidies are used to communicate newsworthy findings to journalists in an effort to earn mass media coverage and further disseminate health science research to mass audiences. Journal editors and news journalists then select which news stories receive coverage and thus public attention. This study aims to identify attributes of published health science articles that correlate with (1) journal editor issuance of press releases and (2) mainstream media coverage. We constructed four novel datasets to identify factors that correlate with press release issuance and media coverage. These corpora include thousands of published articles, subsets of which received press release or mainstream media coverage. We used statistical machine learning methods to identify correlations between words in the science abstracts and press release issuance and media coverage. Further, we used a topic modeling-based machine learning approach to uncover latent topics predictive of the perceived newsworthiness of science articles. Both press release issuance for, and media coverage of, health science articles are predictable from corresponding journal article content. For the former task, we achieved average areas under the curve (AUCs) of 0.666 (SD 0.019) and 0.882 (SD 0.018) on two separate datasets, comprising 3024 and 10,760 articles, respectively. For the latter task, models realized mean AUCs of 0.591 (SD 0.044) and 0.783 (SD 0.022) on two datasets-in this case containing 422 and 28,910 pairs, respectively. We reported most-predictive words and topics for press release or news coverage. We have presented a novel data-driven characterization of content that renders health science "newsworthy." The analysis provides new insights into the news coverage selection process. For example, it appears epidemiological papers concerning common behaviors (eg, alcohol consumption) tend to receive media

    High and continuously increasing research activity related to different aspects of pathogenesis, epidemiology, diagnosis and treatment of glioblastoma has been performed between 2006 and 2010. Different measures of impact, visibility and quality of published research are available, each with its own pros and cons. For this review, article citation rate was chosen. Articles were identified through systematic search of the abstract database PubMed followed by analyses of total number of citations and proportion of highly cited articles, arbitrarily defined as those with ≥100, 50-99, and 25-49 citations, respectively (citation database Scopus). Overall 5831 scientific articles on the subject were published during this time period. 1.5% of all articles accumulated at least 100 citations, 3.2% were cited between 50 and 99 times, and 7.5% were cited between 25 and 49 times. Among the 10 most cited articles, 7 reported on genomic analyses, molecular subclasses of glioblastoma and/or stem cells. Overall, 18 randomized clinical trials were published between 2006 and 2010, including those with phase II design. Thirty-nine percent of them accumulated at least 50 citations and 72% were cited at least 25 times. In general, annual citation rate appeared to gradually increase during the first 2-3 years after publication before reaching high levels. A large variety of preclinical and clinical topics achieved at least 25 citations. However, areas such as quality of life, side effects, and end-of-life care were underrepresented. Efforts to increase their visibility might be warranted. Copyright © 2012 Elsevier B.V. All rights reserved.

    Understanding the nontechnical skills specifically applicable to the emergency department (ED) is essential to facilitate training and more broadly consider interventions to reduce error. The aim of this scoping review is to first identify and then explore in depth the nontechnical skills linked to safety in the ED. The review was conducted in 2 stages. In stage 1, online databases were searched for published empirical studies linking nontechnical skills to safety and performance in the ED. Articles were analyzed to identify key ED nontechnical skills. In stage 2, these key skills were used to generate additional key words, which enabled a second search of the literature to be undertaken and expand on the evidence available for review. In stage 1, 11 articles were retrieved for data analysis and 9 core emergency medicine nontechnical skills were identified. These were communicating, managing workload, anticipating, situational awareness, supervising and providing feedback, leadership, maintaining standards, using assertiveness, and decisionmaking. In stage 2, a secondary search, using these 9 skills and related terms, uncovered a further 21 relevant articles. Therefore, 32 articles were used to describe the main nontechnical skills linked to safety in the ED. This article highlights the challenges of reviewing a topic for which the terms are not clearly defined in the literature. A novel methodological approach is described that provides a structured and transparent process for reviewing the literature in emerging areas of interest. A series of literature reviews focusing on individual nontechnical skills will provide a clearer understanding of how the skills identified contribute to safety in the ED.

    Systematic reviews (SRs) provide high quality evidence for clinical practice, but the article screening process is time and labor intensive. As SRs aim to identify relevant articles with a specific scope, we propose that a pre-defined article relationship, using similarity metrics, could accelerate this process. In this study, we established the article relationship using MEDLINE element similarities and visualized the article network with the Force Atlas layout. We also analyzed the article networks with graph diameter, closeness centrality, and module classes. The results revealed the distribution of articles and found that included articles tended to aggregate together in some module classes, providing further evidence of the existence of strong relationships among included articles. This approach can be utilized to facilitate the articles selection process through early identification of these dominant module classes. We are optimistic that the use of article network visualization can help better SR work prioritization.

    2010-01-01

    This article examines the complex role of early stressful experiences in producing both vulnerability and resilience to later stress-related psychopathology in a variety of primate models of human development. Two types of models are reviewed: Parental Separation Models (e.g., isolate-rearing, peer-rearing, parental separations, and stress inoculation) and Maternal Behavior Models (e.g., foraging demands, variation in maternal style, and maternal abuse). Based on empirical evidence, it is argued that early life stress exposure does not increase adult vulnerability to stress-related psychopathology as a linear function, as is generally believed, but instead reflects a quadratic function. Features of early stress exposure including the type, duration, frequency, ecological validity, sensory modality, and developmental timing, within and between species, are identified to better understand how early stressful experiences alter neurobiological systems to produce such diverse developmental outcomes. This article concludes by identifying gaps in our current knowledge, providing directions for future research, and discussing the translational implications of these primate models for human development and psychopathology.

  1. The Importance of Proper Citation of References in Biomedical Articles

    PubMed Central

    Masic, Izet

    2013-01-01

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original. Authors of every new scientific article need to explain how their study or research fits with previous one in the same or similar fields. A typical article in the health sciences refers to approximately 20-30 other articles published in peer reviewed journals, cite once or hundreds times. Citations typically appear in two formats: a) as in-text citations where the sources of information are briefly identified in the text; or b) in the reference list at the end of the publication (book chapter, manuscript, article, etc.) that provides full bibliographic information for each source. Group of publishers met in Vancouver in 1978 and decided to prescribe uniform technical propositions for publication. Adopted in the 1979 by the National Library of Medicine in Bethesda, then the International Committee of Medical Journals Editors (ICMJE), whose review in 1982 entered the official application by 300 international biomedical journals.

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original.

    Because organ transplantation relies on public support for donation, an analysis of public discourse around organ donation is essential. We investigated the portrayal of family veto - when a family overrides the deceased person's prior legally executed wishes to donate - in Canadian news media. Using the Canadian Newsstream database, we identified articles published in English-language newspapers addressing family veto between 2000 and 2016. Guided by the theoretical perspectives of framing of media effects, we conducted a systematic content analysis of the articles to examine how the Canadian media framed family veto. An initial in-depth analysis of the data set in which themes and patterns were captured and recorded identified coding categories, including primary framing of family veto, prevalence, reasons, ethical or legal concerns and overall tone of the article. Two coders analyzed the data set to ensure intercoder reliability. A total of 133 relevant articles were identified. Family veto was framed predominantly as something that should not be allowed (81 articles [60.9%]) and as a reality that is little understood outside the transplantation community (45 [33.8%]). One-quarter of the articles (32 [24.1%]) highlighted ethical principles of autonomy and justice associated with family veto. Family veto was represented as a stumbling block in the present organ donation system, with most publications (107 [80.4%]) calling for change. There were differing interpretations of organ donation legislation, with 82 articles (61.6%) erroneously stating or suggesting that existing legislation permits family veto. Family veto in organ donation was portrayed predominantly negatively. Many publications reflected a misunderstanding of the law concerning this issue. Although the framing of family veto highlighted important ethical and legal concerns as well as practice and policy considerations, research is needed to enhance the understanding of family veto in organ donation

    OBJECTIVE; There is evidence in academic medicine that the number of authors per paper has increased over time. The goal of this study was to quantitatively analyze authorship trends in the field of radiology over 20 years. A search of the National Library of Medicine MEDLINE database was conducted to identify articles published by radiology departments between 1991 and 2012. Country of origin, article study design, and journal impact factor were recorded. The increase in number of authors per paper was assessed by linear and nonlinear regression. Pearson correlation was used to assess the relation between journal impact factor and number of authors. A total of 142,576 articles and 699,257 authors were identified during the study period. The mean number of authors per paper displayed linear growth from 3.9 to 5.7 (p < 0.0001). The proportion of single authors declined from 11% in 1991 to 4.4% in 2012. The number of clinical trials increased in a linear pattern, review articles in an exponential pattern, and case reports in a logistic pattern (p < 0.0001 for each). Countries with the highest number of authors per paper were Japan, Italy, and Germany. The number of articles funded by the U.S. National Institutes of Health (NIH) displayed exponential growth and of non-NIH-funded articles displayed linear growth (p < 0.0001 for each). A negligible relation was observed between journal impact factor and number of authors (Pearson r = 0.1066). Radiology has had a steady increase in mean number of authors per paper since the early 1990s that has varied by study design. The increase is probably multi-factorial and includes components of author inflation and increasing complexity of research. Findings support the need for reemphasis of authorship criteria to preserve authorship value and accountability.

    Millions of people worldwide use the internet daily as a source of health information. Wikipedia is a popular free online encyclopaedia used by patients and physicians to search for health-related information. Our aim was to evaluate information-seeking behaviour of English-speaking internet users searching Wikipedia for articles related to epilepsy and epileptic seizures. Using Wiki Trends, which provides quantitative information on daily viewing of articles, data on global search queries for Wikipedia articles related to epilepsy and seizures were analysed. The daily Wikipedia article views on syncope, psychogenic non-epileptic seizures, migraine, and multiple sclerosis served as comparative data. The period of analysis covered was from January 2008 to December 2014. Overall, the Wikipedia article "epilepsy and driving" was found to be more frequently visited than the articles "epilepsy and employment" or "epilepsy in children". Since January 2008, the Wikipedia article "multiple sclerosis" was more often visited compared to the articles "epilepsy", "syncope", "psychogenic non-epileptic seizures" or "migraine"; the article "epilepsy" ranked 3,779 and was less frequently visited than "multiple sclerosis", ranked at 571, in traffic on Wikipedia. The highest peak in search volume for the article "epilepsy" coincided with the news of a celebrity having seizures. Fears and worries about epileptic seizures, their impact on driving and employment, and news about celebrities with epilepsy might be major determinants in searching Wikipedia for information.

    2017-01-01

    Systematic Reviews (SRs) of biomedical literature summarize evidence from high-quality studies to inform clinical decisions, but are time and labor intensive due to the large number of article collections. Article similarities established from textual features have been shown to assist in the identification of relevant articles, thus facilitating the article screening process efficiently. In this study, we visualized article similarities to extend its utilization in practical settings for SR researchers, aiming to promote human comprehension of article distributions and hidden patterns. To prompt an effective visualization in an interpretable, intuitive, and scalable way, we implemented a graph-based network visualization with three network sparsification approaches and a distance-based map projection via dimensionality reduction. We evaluated and compared three network sparsification approaches and the visualization types (article network vs. article map). We demonstrated the effectiveness in revealing article distribution and exhibiting clustering patterns of relevant articles with practical meanings for SRs.

    2017-08-01

    The stigma of non-communicable respiratory diseases (NCRDs), whether perceived or otherwise, can be an important element of a patient's experience of his/her illness and a contributing factor to poor psychosocial, treatment and clinical outcomes. This systematic review examines the evidence regarding the associations between stigma-related experiences and patient outcomes, comparing findings across a range of common NCRDs. Electronic databases and manual searches were conducted to identify original quantitative research published to December 2015. Articles focussing on adult patient samples diagnosed with asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, lung cancer or mesothelioma, and included a measurement of stigma-related experience (i.e. perceived stigma, shame, blame or guilt), were eligible for inclusion. Included articles were described for study characteristics, outcome scores, correlates between stigma-related experiences and patient outcomes and methodological rigor. Twenty-five articles were eligible for this review, with most ( n = 20) related to lung cancer. No articles for cystic fibrosis were identified. Twenty unique scales were used, with low to moderate stigma-related experiences reported overall. The stigma-related experiences significantly correlated with all six patient-related domains explored (psychosocial, quality of life, behavioral, physical, treatment and work), which were investigated more widely in COPD and lung cancer samples. No studies adequately met all criteria for methodological rigor. The inter-connectedness of stigma-related experiences to other aspects of patient experiences highlight that an integrated approach is needed to address this important issue. Future studies should adopt more rigorous methodology, including streamlining measures, to provide robust evidence.

    Background There has been limited research investigating the relationship between injurious falls and hospital resource use. The aims of this study were to identify clusters of community-dwelling older people in the general population who are at increased risk of being admitted to hospital following a fall and how those clusters differed in their use of hospital resources. Methods Analysis of routinely collected hospital admissions data relating to 45 374 fall-related admissions in Victorian community-dwelling older adults aged ≥65 years that occurred during 2008/2009 to 2010/2011. Fall-related admission episodes were identified based on being admitted from a private residence to hospital with a principal diagnosis of injury (International Classification of Diseases (ICD)-10-AM codes S00 to T75) and having a first external cause of a fall (ICD-10-AM codes W00 to W19). A cluster analysis was performed to identify homogeneous groups using demographic details of patients and information on the presence of comorbidities. Hospital length of stay (LOS) was compared across clusters using competing risks regression. Results Clusters based on area of residence, demographic factors (age, gender, marital status, country of birth) and the presence of comorbidities were identified. Clusters representing hospitalised fallers with comorbidities were associated with longer LOS compared with other cluster groups. Clusters delineated by demographic factors were also associated with increased LOS. Conclusions All patients with comorbidity, and older women without comorbidities, stay in hospital longer following a fall and hence consume a disproportionate share of hospital resources. These findings have important implications for the targeting of falls prevention interventions for community-dwelling older people. PMID:25618735

    Systems and methods for fabricating multi-functional articles comprised of additively formed gradient materials are provided. The fabrication of multi-functional articles using the additive deposition of gradient alloys represents a paradigm shift from the traditional way that metal alloys and metal/metal alloy parts are fabricated. Since a gradient alloy that transitions from one metal to a different metal cannot be fabricated through any conventional metallurgy techniques, the technique presents many applications. Moreover, the embodiments described identify a broad range of properties and applications.

    2014-08-01

    This research analyses what happens when a critical reading activity based on a press article dealing with an energy-related problem is implemented with two groups of students of 13-14 years old and 16-17 years old in the same school (a total of 117 students). Specifically, the research analyses the students' profiles from the standpoint of their attitudes to the information given in the news story and the use they make of it when writing an argumentative text. It also analyses the difficulties the students have when it comes to applying their knowledge about energy in a real-life context. Lastly, some strategies are suggested for helping students to critically analyse the scientific content of a newspaper article. Three reader profiles were identified (the credulous reader, the ideological reader and the critical reader). No significant differences were found in reading profiles in terms of age or scientific knowledge. The findings show that the activity helped to link science learning in school with facts relating to an actual context, particularly in the case of students with more science knowledge.

    In this work we study how people navigate the information network of Wikipedia and investigate (i) free-form navigation by studying all clicks within the English Wikipedia over an entire month and (ii) goal-directed Wikipedia navigation by analyzing wikigames, where users are challenged to retrieve articles by following links. To study how the organization of Wikipedia articles in terms of layout and links affects navigation behavior, we first investigate the characteristics of the structural organization and of hyperlinks in Wikipedia and then evaluate link selection models based on article structure and other potential influences in navigation, such as the generality of an article's topic. In free-form Wikipedia navigation, covering all Wikipedia usage scenarios, we find that click choices can be best modeled by a bias towards article structure, such as a tendency to click links located in the lead section. For the goal-directed navigation of wikigames, our findings confirm the zoom-out and the homing-in phases identified by previous work, where users are guided by generality at first and textual similarity to the target later. However, our interpretation of the link selection models accentuates that article structure is the best explanation for the navigation paths in all except these initial and final stages. Overall, we find evidence that users more frequently click on links that are located close to the top of an article. The structure of Wikipedia articles, which places links to more general concepts near the top, supports navigation by allowing users to quickly find the better-connected articles that facilitate navigation. Our results highlight the importance of article structure and link position in Wikipedia navigation and suggest that better organization of information can help make information networks more navigable.

    2017-05-01

    In the home healthcare setting, clinicians are required to evaluate patient's medication therapy, including adherence. To facilitate this conversation, a pilot question list to help uncover potential medication nonadherence was created after completing a review of the literature and ascertaining the common themes as to why patients were nonadherent to their medication therapies. Pharmacy personnel who provide onsite consultations in a home healthcare setting used the question list to identify medication-related problems that could contribute to nonadherence and to document potential solutions. Through pharmacist-patient interactions, which occurred after admission to the home healthcare agency, pharmacy personnel found on average 2.3 issues per patient, which could affect medication adherence. Side effects were the most common problem identified. After this tool was tested with 65 patient interviews, the questions were analyzed and condensed into a shorter list more specific to the identification of medication-related problems for use by home care clinicians.

    Exploring new analysis techniques to enhance our knowledge of the various metabolites within our soil systems is imperative. Principally, this knowledge would allow us to link key metabolites with functional influences on critical nutrient processes, such as the nitrogen (N) mineralisation in soils. Currently there are few studies that utilize proton nuclear magnetic resonance spectroscopy (1H NMR) to characterize multiple metabolites within a soil sample. The aim of this research study was to examine the effectiveness of 1H NMR for isolating multiple metabolites that are related to the mineralizable N (MN) capacity across a range of 35 Irish grassland soils. Soils were measured for MN using the standard seven day anaerobic incubation (AI-7). Additionally, soils were also analysed for a range of physio-chemical properties [e.g. total N, total C, mineral N, texture and soil organic matter (SOM)]. Proton NMR analysis was carried on these soils by extracting with 40% methanol:water, lyophilizing and reconstituting in deuterium oxide and recording the NMR spectra on a 400MHz Bruker AVANCE III spectrometer. Once the NMR data were spectrally processed and analysed using multivariate statistical analysis, seven metabolites were identified as having significant relationships with MN (glucose, trimethylamine, glutamic acid, serine, aspartic acid, 4-aminohippuirc acid and citric acid). Following quantification, glucose was shown to explain the largest percentage variability in MN (72%). These outcomes suggest that sources of labile carbon are essential in regulating N mineralisation and the capacity of plant available N derived from SOM-N pools in these soils. Although, smaller in concentration, the amino acids; 4-aminohippuirc acid, glutamic acid and serine also significantly (P<0.05) explained 43%, 27% and 19% of the variability in MN, respectively. This novel study highlights the effectiveness of using 1H NMR as a practical approach to profile multiple metabolites in

    Easy availability, preparation technique, and economic value make calcium polysulphide (CaS x ) a very useful inorganic chemical for various field and industrial applications. In this article, disparate applications of CaS x solution have been reviewed to suggest potential and future consolidation. This article also encompasses the physiochemical properties and production of CaS x solution, with critical appraisal on research focusing on CaS x application in agriculture industries and removal of potentially toxic elements (PTEs) from the environment. The kinetics of CaS x , technical issues associated with optimization of its dosage and environmental fate is also discussed in detail. This study covers almost all of the peer-reviewed research that has been performed since 1914. Some of the critiques in this article include the lack of integration between the exposure effect and the efficiency of treatment method, effects of oxidizing environments on the long-term performance of CaS x solution, and kinetics of CaS x solution with the PTEs. The working model of CaS x with PTEs is still system dependent, and therefore cannot be used with other applications. The kinetics of CaS x is described in detail with various phase stoichiometric reactions. Environmental fate is discussed based on applications, government reports, peer-reviewed articles and kinetics of CaS x , which provides a clear picture of emerging contaminants in the environment in relation to the insect resistance and ecotoxicology. Real time, lab based research articles are needed to identify toxicity limits of CaS x in environment in order to describe its effective permissible limit in environmental system. This review article provides a risk assessment of environmental pollution by CaS x based on its physicochemical characteristic, stoichiometry, kinetics, field, and industrial applications.

  3. Medical school libraries' handling of articles that report invalid science.

    1992-02-01

    In 1989-90 the authors conducted a nationwide study to examine how academic medical libraries handled articles that report invalid science and to determine the effectiveness of any policies implemented to limit the use of such articles. Ninety-five of the 127 medical school libraries the authors surveyed completed questionnaires analyzing policy and attitude issues. Eighty-four of these libraries manually reviewed the available copies they held of ten retracted articles. Of the 811 copies of the retracted, invalid articles reviewed, 742 (91.5%) were not tagged as being invalid. Seventy-nine percent of the libraries had tagged none of the retracted studies and only 16% had policies for managing articles that report invalid science. Academic librarians reflected a common attitude against perceived library censorship and emphasized the user's role in assuring validity. The nation's medical libraries, at least in part by intent, do not commonly identify or have policies to handle the invalid articles they hold. The authors conclude that biomedical researchers, clinicians, and teachers should not assume published studies held in libraries are inherently valid. The lack of stated policy and the disparate assumptions about the role libraries play in this area may perpetuate the use of invalid articles.

    The purpose of this study was to investigate differences between abstracts of posters presented at the 79(th) (2002) and 80(th) (2003) Annual Session & Exhibition of the American Dental Education Association (ADEA) and the published full-length articles resulting from the same studies. The abstracts for poster presentation sessions were downloaded, and basic characteristics of the abstracts and their authors were determined. A PubMed search was then performed to identify the publication of full-length articles based on those abstracts in a peer-reviewed journal. The differences between the abstract and the article were examined and categorized as major and minor differences. Differences identified included authorship, title, materials and methods, results, conclusions, and funding. Data were analyzed with both descriptive and analytic statistics. Overall, 89 percent of the abstracts had at least one variation from its corresponding article, and 65 percent and 76 percent of the abstracts had at least one major and minor variation, respectively, from its corresponding article. The most prevalent major variation was in study results, and the most prevalent minor variation was change in the number of authors. The discussion speculates on some possible reasons for these differences.

  5. Identifying and reducing risk factors related to trainee-client sexual misconduct.

    1999-06-01

    Sexual misconduct involving therapists-in-training and their clients is addressed. Personal and situational factors that may constitute risk factors for the development of inappropriate sexual activity between trainees and their clients are identified. Although there may be certain characteristics that put particular students at risk for such involvement, the authors believe this risk is more strongly related to systemic, programmatic, and pedagogic characteristics of the environments in which students train. Examples include, respectively, the decline of concern over transference and countertransference, failure to include education about client-therapist sexual attraction and the consequences of sexual misconduct in graduate psychology curricula, and the reluctance of supervisors to deal straightforwardly with trainees' sexual feelings. Suggestions for reducing risks for client-therapist sexual misconduct are directed toward these situational factors.

However, no study has analyzed the quality of the most cited articles in elbow medial ulnar collateral ligament (UCL) surgery. To (1) identify the top 50 most cited articles related to UCL surgery, (2) determine whether there was a correlation between the top cited articles and level of evidence, and (3) determine whether there was a correlation between study methodological quality and the top cited articles. Systematic review. Web of Science and Scopus online databases were searched to identify the top 50 cited articles in UCL surgery. Level of evidence, number of times cited, year of publication, name of journal, country of origin, and study type were recorded for each study. Study methodological quality was analyzed for each article with the Modified Coleman Methodology Score (MCMS) and the Methodological Index for Non-randomized Studies (MINORS). Correlation coefficients were calculated. The 50 most cited articles were published between 1981 and 2015. The number of citations per article ranged from 20 to 301 (mean ± SD, 71 ± 62 citations). Most articles (92%) were from the United States and were level 3 (16%), level 4 (58%), or unclassified (16%) evidence. There were no articles of level 1 evidence quality. The mean MCMS and MINORS scores were 28.1 ± 13.4 (range, 3-52) and 9.2 ± 3.6 (range, 2-19), respectively. There was no significant correlation between the mean number of citations and level of evidence or quality ( r s = -0.01, P = .917), MCMS ( r s = 0.09, P = .571), or MINORS ( r s = -0.26, P = .089). The top 50 cited articles in UCL surgery constitute a low level of evidence and low methodological quality, including no level 1 articles. There was no significant correlation between the mean number of citations and level of evidence or study methodological quality. However, weak correlations were observed for later publication date and

    Since the genome project in 1990s, a number of studies associated with genes have been conducted and researchers have confirmed that genes are involved in disease. For this reason, the identification of the relationships between diseases and genes is important in biology. We propose a method called LGscore, which identifies disease-related genes using Google data and literature data. To implement this method, first, we construct a disease-related gene network using text-mining results. We then extract gene-gene interactions based on co-occurrences in abstract data obtained from PubMed, and calculate the weights of edges in the gene network by means of Z-scoring. The weights contain two values: the frequency and the Google search results. The frequency value is extracted from literature data, and the Google search result is obtained using Google. We assign a score to each gene through a network analysis. We assume that genes with a large number of links and numerous Google search results and frequency values are more likely to be involved in disease. For validation, we investigated the top 20 inferred genes for five different diseases using answer sets. The answer sets comprised six databases that contain information on disease-gene relationships. We identified a significant number of disease-related genes as well as candidate genes for Alzheimer's disease, diabetes, colon cancer, lung cancer, and prostate cancer. Our method was up to 40% more accurate than existing methods. Copyright © 2015 Elsevier Inc. All rights reserved.

  8. Identifying opinion leaders to promote behavior change.

    Valente, Thomas W; Pumpuang, Patchareeya

    2007-12-01

    This article reviews 10 techniques used to identify opinion leaders to promote behavior change. Opinion leaders can act as gatekeepers for interventions, help change social norms, and accelerate behavior change. Few studies document the manner in which opinion leaders are identified, recruited, and trained to promote health. The authors categorize close to 200 studies that have studied or used opinion leaders to promote behavior change into 10 different methods. They present the advantages and disadvantages of the 10 opinion leader identification methods and provide sample instruments for each. Factors that might influence programs to select one or another method are then discussed, and the article closes with a discussion of combining and comparing methods.

    To identify the 100 top-cited articles published in orthodontics journals and to analyze their characteristics to investigate the achievement and development of orthodontics research in past decades. The Institute for Scientific Information Web of Knowledge Database and the 2011 Journal Citation Report Science Editions were used to retrieve the 100 top-cited articles published in orthodontics journals since 1975. Some basic information was collected by the Analyze Tool on the Web of Science, including citation time, publication title, journal name, publication year, and country and institution of origin. A further study was then performed to determine authorship, article type, field of study, study design, and level of evidence. The 100 target articles were retrieved from three journals: American Journal of Orthodontics and Dentofacial Orthopedics (n  =  74), The Angle Orthodontist (n = 15), and European Journal of Orthodontics (n  =  11). Since 1975, the articles cited 89 to 545 times mainly originated from the United States, and the overwhelming majority of articles were clinical. The most common study design was case series; 40 articles were classified as level IV and 12 as level V evidence. The 100 top-cited articles in orthodontics are generally old articles, rarely possessing high-level evidence.

    Background: It might be difficult for clinicians and scientists to identify comprehensively the major research topics given the large number of publications. A bibliometric report that identifies the most-cited articles within the body of the relevant literature may provide insight and guidance for readers toward scientific topics that are considered important for researchers and all relevant workers of academia. To our knowledge, there is a lack of an overall evaluation of the most-cited articles and hence of a comprehensive review of major research topics in neuroscience. The present study was therefore proposed to analyze and characterize the 100 most-cited articles in neuroscience. Methods: Based on data provided from Web of Science, the 100 most-cited articles relevant to neuroscience were identified and characterized. Information was extracted for each included article to assess for the publication year, journal published, impact factor, adjusted impact factor, citation count (total, normalized, and adjusted), reference list, authorship and article type. Results: The total citation count for the 100 most-cited articles ranged from 7,326 to 2,138 (mean 3087.0) and the normalized citation count ranged from 0.163 to 0.007 (mean 0.054). The majority of the 100 articles were research articles (67%) and published from 1996 to 2000 (30%). The author and journal with the largest share of these 100 articles were Stephen M. Smith (n = 6) and Science (n = 13) respectively. Among the 100 most-cited articles, 37 were interlinked via citations of one another, and they could be classified into five major topics, four of which were scientific topics, namely neurological disorders, prefrontal cortex/emotion/reward, brain network, and brain mapping. The remaining topic was methodology. Interestingly 41 out of 63 of the rest, non-interlinked articles could also be categorized under the above five topics. Adjusted journal impact factor among these 100 articles did not appear to

    To determine the 50 most cited articles in orthopedic cartilage surgery and their characteristics. A systematic review of the Science Citation Index Expanded was performed for articles related to cartilage surgery published in the 66 journals under the category "Orthopedics." The 50 most cited articles were determined, and the following characteristics were analyzed for each article: authors, journal and year of publication, number of citations, geographic origin, article type (basic science or clinical), article subtype by study design, and level of evidence. Citation density (total number of citations/years since publication) was also computed. The 50 most cited articles ranged from 989 to 172 citations, with citation density ranging from 71.5 to 4.1. The publication years spanned from 1968 to 2008, with the 2000s accounting for half (25) of the articles and the highest mean citation density (14.6). The 50 most cited articles were published in 11 journals. The majority of the articles (29) were clinical, with level IV representing the most common level of evidence (10). The remaining basic science articles were most commonly animal in vivo studies (14). Stronger level of evidence was correlated with overall number of citations (P = 0.044), citation density (P < 0.001), and year of publication (P = 0.003). Articles with stronger levels of evidence are more highly cited, with an increasing trend as evidence-based practice has been emphasized. This article list provides clinicians, researchers, and trainees with a group of "citation classics" in orthopedic cartilage surgery.

    2008-11-01

    The purpose of the study was to analyze the content of popular press magazine articles that focused on postpartum depression, published from 1998-2006. Replicating earlier research by Martinez, Johnson-Robledo, Ulsh, and Chrisler, 2000, 47 articles were identified and their content analyzed in the areas of etiology, symptoms, treatment, resources, and demographic assumptions about readers. Popular press magazines contained contradictory information about the definition, prevalence, onset, duration, symptoms, and treatment of postpartum mood disorders. Health care providers should be proactive in directing childbearing women to factual sources of information on postpartum depression.

  15. EDdb: a web resource for eating disorder and its application to identify an extended adipocytokine signaling pathway related to eating disorder.

    Eating disorder is a group of physiological and psychological disorders affecting approximately 1% of the female population worldwide. Although the genetic epidemiology of eating disorder is becoming increasingly clear with accumulated studies, the underlying molecular mechanisms are still unclear. Recently, integration of various high-throughput data expanded the range of candidate genes and started to generate hypotheses for understanding potential pathogenesis in complex diseases. This article presents EDdb (Eating Disorder database), the first evidence-based gene resource for eating disorder. Fifty-nine experimentally validated genes from the literature in relation to eating disorder were collected as the core dataset. Another four datasets with 2824 candidate genes across 601 genome regions were expanded based on the core dataset using different criteria (e.g., protein-protein interactions, shared cytobands, and related complex diseases). Based on human protein-protein interaction data, we reconstructed a potential molecular sub-network related to eating disorder. Furthermore, with an integrative pathway enrichment analysis of genes in EDdb, we identified an extended adipocytokine signaling pathway in eating disorder. Three genes in EDdb (ADIPO (adiponectin), TNF (tumor necrosis factor) and NR3C1 (nuclear receptor subfamily 3, group C, member 1)) link the KEGG (Kyoto Encyclopedia of Genes and Genomes) "adipocytokine signaling pathway" with the BioCarta "visceral fat deposits and the metabolic syndrome" pathway to form a joint pathway. In total, the joint pathway contains 43 genes, among which 39 genes are related to eating disorder. As the first comprehensive gene resource for eating disorder, EDdb ( http://eddb.cbi.pku.edu.cn ) enables the exploration of gene-disease relationships and cross-talk mechanisms between related disorders. Through pathway statistical studies, we revealed that abnormal body weight caused by eating disorder and obesity may both be

    The total number of citations of a research article can be used to determine its impact on the scientific community. We aimed to identify the top-100 articles published on ischemic stroke and evaluate their characteristics. Based on the database of Journal Citation Reports, 934 journals were selected that published original ischemic stroke articles. We used Web of Science citation search tool to identify top-100 citation classics, i.e., articles with more than 400 citations, in the field of ischemic stroke. All original articles were evaluated for publication year, journal category, journal and its impact factor, number of total and annual citations, research topic, publishing country, and institutional affiliation. The top-100 citation classics in ischemic stroke were published from 1970 to 2015, with the decade of 1990-1999 contributing 47 articles of historical significance. Median of total citations and annual citations in our analysis were 625.0 (interquartile range [IQR] 851.3-494.5) and 35.7 (IQR 79.9-25.9), respectively. The majority of the articles originated from the United States (n = 57), focused over the medical management (n = 26), and were published in the New England Journal of Medicine or Stroke (n = 25 each) journals. The median impact factor for the journals that published top-100 ischemic stroke citation classics was 9.11 (IQR 21.49-6.11). Our list of top-100 citation classics specific to ischemic stroke provide a detailed insight into academic achievements, historical perspective and serves as a guide for the scientific progress in stroke.

    Gastric carcinoids (GCs) or neuroendocrine tumours (NETs) are increasingly identified at endoscopy, and account for 0.6-2% of all gastric polyps identified. The SEER database in the US has demonstrated a rising incidence of gastric NETs amongst all NETs; from 2.2% between 1950 and 1969 to 6.0% between 2000 and 2007. To review the literature and assist clinicians in managing patients with GCs. A literature search was conducted through MEDLINE using search terms: gastric, carcinoid, neuroendocrine tumour, therapy, endoscopy, mucosal resection, submucosal dissection. Relevant articles were identified through manual review. The reference lists of these articles were reviewed to include further appropriate articles. There are three types of GCs with important epidemiological, pathophysiological, histological and endoscopic differences that affect prognosis and management. Type 1 and 2 GCs develop in the context of hypergastrinaemia that originates from achlorhydria in atrophic gastritis and a gastrinoma, respectively. Type 3 GCs occur sporadically and independent of gastrin. The histological type, grade and Ki67 index are used to determine prognosis and direct clinical management. Type 1 GCs >1 cm in size and type 2 GCs should be assessed for invasion beyond the submucosa with EUS prior to endoscopic resection with EMR or ESD. Type 3 GCs should be managed as per recommendations for gastric adenocarcinoma. The treatment of advanced disease is multimodal. Patients with gastric carcinoids should be discussed in a specialist neuroendocrine tumour multidisciplinary meeting to ensure all treatment options are explored in localised and advanced disease. Areas of controversy exist that need further research. © 2014 John Wiley & Sons Ltd.

    Objectives. To evaluate scholarship, as represented by peer-reviewed journal articles, among US pharmacy practice faculty members; contribute evidence that may better inform benchmarking by academic pharmacy practice departments; and examine factors that may be related to publication rates. Methods. Journal articles published by all pharmacy practice faculty members between January 1, 2006, and December 31, 2010, were identified. College and school publication rates were compared based on public vs. private status, being part of a health science campus, having a graduate program, and having doctor of pharmacy (PharmD) faculty members funded by the National Institutes of Health (NIH). Results. Pharmacy practice faculty members published 6,101 articles during the 5-year study period, and a pharmacy practice faculty member was the primary author on 2,698 of the articles. Pharmacy practice faculty members published an average of 0.51 articles per year. Pharmacy colleges and schools affiliated with health science campuses, at public institutions, with NIH-funded PharmD faculty members, and with graduate programs had significantly higher total publication rates compared with those that did not have these characteristics (p<0.006). Conclusion. Pharmacy practice faculty members contributed nearly 6,000 unique publications over the 5-year period studied. However, this reflects a rate of less than 1 publication per faculty member per year, suggesting that a limited number of faculty members produced the majority of publications. PMID:23049099

    Bibliometric analysis highlights the key topics and publications, which have shaped surgical education. Here, the 100 most cited articles in the arena of surgical education were analyzed. Thomson Reuters Web of Science was interrogated using the keyword search terms "surgery" and ("learning" or "skills" or "competence" or "assessment" or "training" or "procedure-based assessments" or "performance" or "technical skills" or "curriculum" or "education" or "mentoring"] to identify all English language full articles, and the 100 most cited articles were analyzed by topic, journal, author, year, institution, and country of origin. A total of 403,733 eligible articles were returned and the median citation number was 164 (range: 107-1018). The most cited article (by Seymour, Yale University School of Medicine, Annals of Surgery, 1018 citations) focused on the use of virtual reality surgical simulation training. Annals of Surgery published the highest number of articles and received the most citations (n = 16, 3715 citations). The countries with the greatest number of publications were the USA (n = 45), Canada (n = 19), and the UK (n = 18). The commonest topics included simulation (n = 45) and assessment of clinical competence (n = 40). Surgical skill acquisition and assessment was the area of focus of 85% of the most cited contemporary articles, and this study provides the most cited references, serving as a guide as to what makes a citable published work in the field of surgical education.

  9. PageRank without hyperlinks: Reranking with PubMed related article networks for biomedical text retrieval

    PubMed Central

    Lin, Jimmy

    2008-01-01

    Background Graph analysis algorithms such as PageRank and HITS have been successful in Web environments because they are able to extract important inter-document relationships from manually-created hyperlinks. We consider the application of these techniques to biomedical text retrieval. In the current PubMed® search interface, a MEDLINE® citation is connected to a number of related citations, which are in turn connected to other citations. Thus, a MEDLINE record represents a node in a vast content-similarity network. This article explores the hypothesis that these networks can be exploited for text retrieval, in the same manner as hyperlink graphs on the Web. Results We conducted a number of reranking experiments using the TREC 2005 genomics track test collection in which scores extracted from PageRank and HITS analysis were combined with scores returned by an off-the-shelf retrieval engine. Experiments demonstrate that incorporating PageRank scores yields significant improvements in terms of standard ranked-retrieval metrics. Conclusion The link structure of content-similarity networks can be exploited to improve the effectiveness of information retrieval systems. These results generalize the applicability of graph analysis algorithms to text retrieval in the biomedical domain. PMID:18538027

    This article describes a systematic analysis of the relationship between empirical data and theoretical conclusions for a set of experimental psychology articles published in the journal Science between 2005-2012. When the success rate of a set of empirical studies is much higher than would be expected relative to the experiments' reported effects and sample sizes, it suggests that null findings have been suppressed, that the experiments or analyses were inappropriate, or that the theory does not properly follow from the data. The analyses herein indicate such excess success for 83% (15 out of 18) of the articles in Science that report four or more studies and contain sufficient information for the analysis. This result suggests a systematic pattern of excess success among psychology articles in the journal Science.

    Orthopedic sports medicine continues to evolve, owing much of its clinical management and practice to rigorous academic research. In this review, we identify and describe the top 100 cited articles in clinical sports medicine and recognize the authors and institutions driving the research. We collected articles (excluding basic science, animal, and cadaveric studies) from the 25 highest-impact sports medicine journals and analyzed them by number of citations, journal, publication date, institution, country, topic, and author. Mean number of citations was 408 (range, 229-1629). The articles were published in 7 journals, most in the 1980s to 2000s, and represented 15 countries. Thirty topics were addressed, with a heavy emphasis on anterior cruciate ligament injury and reconstruction, knee rating systems, rotator cuff reconstruction, and chondrocyte transplantation. The 3 most cited articles, by Insall and colleagues, Constant and Murley, and Tegner and Lysholm, addressed a knee, a shoulder, and another knee rating system, respectively. Several authors contributed multiple articles. The Hospital for Special Surgery and the University of Bern contributed the most articles (5 each). This study provides a comprehensive list of the past century's major academic contributions to sports medicine. Residents and fellows may use this list to guide their scholarly investigations.

  14. Improving accuracy for identifying related PubMed queries by an integrated approach.

    PubMed

    Lu, Zhiyong; Wilbur, W John

    2009-10-01

    PubMed is the most widely used tool for searching biomedical literature online. As with many other online search tools, a user often types a series of multiple related queries before retrieving satisfactory results to fulfill a single information need. Meanwhile, it is also a common phenomenon to see a user type queries on unrelated topics in a single session. In order to study PubMed users' search strategies, it is necessary to be able to automatically separate unrelated queries and group together related queries. Here, we report a novel approach combining both lexical and contextual analyses for segmenting PubMed query sessions and identifying related queries and compare its performance with the previous approach based solely on concept mapping. We experimented with our integrated approach on sample data consisting of 1539 pairs of consecutive user queries in 351 user sessions. The prediction results of 1396 pairs agreed with the gold-standard annotations, achieving an overall accuracy of 90.7%. This demonstrates that our approach is significantly better than the previously published method. By applying this approach to a one day query log of PubMed, we found that a significant proportion of information needs involved more than one PubMed query, and that most of the consecutive queries for the same information need are lexically related. Finally, the proposed PubMed distance is shown to be an accurate and meaningful measure for determining the contextual similarity between biological terms. The integrated approach can play a critical role in handling real-world PubMed query log data as is demonstrated in our experiments.

    Background Bibliometric science employs statistical and quantitative analyses to analyse the scholarly impact and characteristics of publications within a research field. The present study was initiated to analyse and quantify the 100 most often cited papers in glaucoma research. Materials and Methods The databases of the Institute for Scientific Information were utilised for the identification of articles published from 1900 to December 2016. All glaucoma articles were identified that had been published in 109 relevant journals and which had been cited at least 200 times. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. Results The publication dates of the 100 most often cited articles ranged from 1966 to 2011, with the greatest number of articles published in the 1990s. Citations per article ranged from 258 to 1908. All articles were published in 18 of the 109 journals. The leading countries of origin were the U. S. A., followed by the U. K. The study focussed on two main clinical articles (diagnostics; epidemiology) and basic research articles. The number of citations per article was greatest for articles published in the 2000s. Most articles provided level III evidence, followed by levels I and II. Conclusion The majority of the most cited articles were published in three of the top-ranked journals. Most clinical articles dealt with epidemiology and diagnostics. Individuals who authored multiple articles in the list often focussed on one of these two areas. Most studies were conducted in the U. S. A. and presented level III clinical outcomes. This indicates that even studies with small case series or cohort studies can attract attention.

  16. Memory-Augmented Active Deep Learning for Identifying Relations Between Distant Medical Concepts in Electroencephalography Reports.

    PubMed

    Maldonado, Ramon; Goodwin, Travis R; Harabagiu, Sanda M

    2018-01-01

    The automatic identification of relations between medical concepts in a large corpus of Electroencephalography (EEG) reports is an important step in the development of an EEG-specific patient cohort retrieval system as well as in the acquisition of EEG-specific knowledge from this corpus. EEG-specific relations involve medical concepts that are not typically mentioned in the same sentence or even the same section of a report, thus requiring extraction techniques that can handle such long-distance dependencies. To address this challenge, we present a novel frame work which combines the advantages of a deep learning framework employing Dynamic Relational Memory (DRM) with active learning. While DRM enables the prediction of long-distance relations, active learning provides a mechanism for accurately identifying relations with minimal training data, obtaining an 5-fold cross validationF1 score of 0.7475 on a set of 140 EEG reports selected with active learning. The results obtained with our novel framework show great promise.

    The number of citations that an article has received can be used to evaluate its impact on the scientific community. This study aimed to identify the 100 most cited articles in the field of neurointervention and to analyze their characteristics. We selected the 669 journals that were considered potentially to publish neurointervention articles based on the database of Journal Citation Reports. Using the Web of Science citation search tool, we identified the 100 most cited articles relevant to neurointervention within the selected journals. Each article was evaluated for several characteristics including publication year, journal, journal category, impact factor, number of citations, number of citations per year, authorship, department, institution, country, type of article, and topic. The number of citations for the top 100 articles ranged from 1912 to 170 (mean 363.4) and citations per year ranged from 271.0 to 4.1 (mean 40.0). The majority of articles were published in clinical neurology journals (63%), were published in 2000-2009 (39%), originated in the USA (45%), were original articles (95%), and dealt with endovascular treatment of cerebral aneurysm (42%). The Department of Radiology, University of California School of Medicine (n=12) was the leading institution and Viñuela F (n=11) was the most prolific author. Our study presents a detailed list and analysis of the 100 most cited articles in the field of neurointervention and provides a historical perspective on the scientific progress in this field.

    2017-09-01

    Background: Obesity is an established risk factor for renal cell carcinoma (RCC). Although genome-wide association studies (GWAS) of RCC have identified several susceptibility loci, additional variants might be missed due to the highly conservative selection. Methods: We conducted a multiphase study utilizing three independent genome-wide scans at MD Anderson Cancer Center (MDA RCC GWAS and MDA RCC OncoArray) and National Cancer Institute (NCI RCC GWAS), which consisted of a total of 3,530 cases and 5,714 controls, to investigate genetic variations in obesity-related genes and RCC risk. Results: In the discovery phase, 32,946 SNPs located at ±10 kb of 2,001 obesity-related genes were extracted from MDA RCC GWAS and analyzed using multivariable logistic regression. Proxies ( R 2 > 0.8) were searched or imputation was performed if SNPs were not directly genotyped in the validation sets. Twenty-one SNPs with P < 0.05 in both MDA RCC GWAS and NCI RCC GWAS were subsequently evaluated in MDA RCC OncoArray. In the overall meta-analysis, significant ( P < 0.05) associations with RCC risk were observed for SNP mapping to IL1RAPL2 [rs10521506-G: OR meta = 0.87 (0.81-0.93), P meta = 2.33 × 10 -5 ], PLIN2 [rs2229536-A: OR meta = 0.87 (0.81-0.93), P meta = 2.33 × 10 -5 ], SMAD3 [rs4601989-A: OR meta = 0.86 (0.80-0.93), P meta = 2.71 × 10 -4 ], MED13L [rs10850596-A: OR meta = 1.14 (1.07-1.23), P meta = 1.50 × 10 -4 ], and TSC1 [rs3761840-G: OR meta = 0.90 (0.85-0.97), P meta = 2.47 × 10 -3 ]. We did not observe any significant cis-expression quantitative trait loci effect for these SNPs in the TCGA KIRC data. Conclusions: Taken together, we found that genetic variation of obesity-related genes could influence RCC susceptibility. Impact: The five identified loci may provide new insights into disease etiology that reveal importance of obesity-related genes in RCC development.

    A growing body of research aims to identify the factors that motivate people to make contributions in Wikipedia. We conducted two laboratory experiments to investigate the connections between topic characteristics, perception of threat, and willingness to engage with Wikipedia articles. In Study 1 (N = 83), we examined how topic familiarity, topic controversiality, and mortality salience influenced participants’ willingness to engage with Wikipedia articles. We presented the introduction parts of 20 Wikipedia articles and asked participants to rate each article with respect to familiarity and controversiality. In addition, we experimentally manipulated participants’ level of mortality salience in terms of the amount of threat they experienced when reading the article. Participants also indicated their willingness to engage with a particular article. The results revealed that familiar and controversial topics increased the willingness to engage with Wikipedia articles. Although mortality salience increased accessibility of death-related thoughts, it did not result in any changes in people’s willingness to work with the articles. The aim of Study 2 (N = 90) was to replicate the effects of topic characteristics by following a similar procedure. We additionally manipulated uncertainty salience by assigning participants to three experimental conditions: uncertainty salience, certainty salience, and non-salience. As expected, familiar and controversial topics were of high interest in terms of willingness to contribute. However, the manipulation of uncertainty salience did not yield any significant results despite the emergence of negative emotional states. In sum, we demonstrated that topic characteristics were factors that substantially influenced people’s willingness to engage with Wikipedia articles whereas perceived threat was not. PMID:29163323

    The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited articles may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997 to 2007. We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997 to 2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164 377 articles in 222 cardiovascular journals from 1997 to 2007. From 1997 to 2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2%, respectively. Of all the articles, 75 550 (46.0%) were poorly cited, of which 25 650 (15.6% overall) had no citations. From 1997 to 2007, the proportion of poorly cited articles declined slightly (52.1%-46.2%, trend P<0.001), although the absolute number of poorly cited articles increased by 2595 (trend P<0.001). At a journal level, 44% of cardiovascular journals had more than three-fourths of the journal's content poorly cited at 5 years. Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature and the number of poorly cited articles both increased substantially from 1997 to 2007. The high proportion of poorly cited articles and journals suggests inefficiencies in the cardiovascular research enterprise. © 2015 American Heart Association, Inc.

  4. Integrating GPCR-specific information with full text articles

    Background With the continued growth in the volume both of experimental G protein-coupled receptor (GPCR) data and of the related peer-reviewed literature, the ability of GPCR researchers to keep up-to-date is becoming increasingly curtailed. Results We present work that integrates the biological data and annotations in the GPCR information system (GPCRDB) with next-generation methods for intelligently exploring, visualising and interacting with the scientific articles used to disseminate them. This solution automatically retrieves relevant information from GPCRDB and displays it both within and as an adjunct to an article. Conclusions This approach allows researchers to extract more knowledge more swiftly from literature. Importantly, it allows reinterpretation of data in articles published before GPCR structure data became widely available, thereby rescuing these valuable data from long-dormant sources.

    Benton, Samuel T.

    1976-01-01

    This invention is directed to the fabrication of boron articles by a powder metallurgical method wherein the articles are of a density close to the theoretical density of boron and are essentially crackfree. The method comprises the steps of admixing 1 to 10 weight percent carbon powder with amorphous boron powder, cold pressing the mixture and then hot pressing the cold pressed compact into the desired article. The addition of the carbon to the mixture provides a pressing aid for inhibiting the cracking of the hot pressed article and is of a concentration less than that which would cause the articles to possess significant concentrations of boron carbide.

  6. Eight questions to ask before writing an article.

    PubMed

    Albert, Tim

    2017-06-02

    Health professionals often have to write articles for publication in academic journals. Many of them find this difficult and suffer from one or more variations of writer's block. A good way of avoiding these setbacks is to prepare thoroughly for the writing project, and this article proposes eight different questions writers can ask before they start. The first is whether they are in a good position to complete the task, and if not whether they should try to negotiate their way out of the project. If they commit to going ahead, writers should work out where they will find the necessary time, and set deadlines for ensuring that they do. They should also decide on their co-authors, because getting them involved early should make the rewriting more straightforward as well as reducing the danger of ghost authors emerging once the work has been done. Writers should put their research away and reflect on the most appropriate message - a simple sentence that sums up the main implication of the paper. Armed with this message, they can identify a suitable journal for publication - and thereafter can use articles in this journal to guide them on matters of substance and style. If the article is published in that target journal authors can consider that they have written a successful paper.

    2016-11-01

    The number of citations an article receives has been used as a marker of its influence within a surgical specialty. Currently, there is limited citation analysis in oral and maxillofacial trauma surgery. The purpose of this study was to determine the 100 most cited articles in facial trauma surgery and their characteristics. Articles were identified from the Science Citation Index of the Institute for Scientific Information using the Thomson Reuters Web of Science search engine. All articles until 2015 were included. Then, the 100 most cited articles were assessed for title, author, journal, country of origin, and number of citations. A citation index (number of citations received per year) also was calculated. The 100 most cited articles in facial trauma received 9,933 citations (range, 66 to 297). They were published from 1942 through 2008, with 1990 through 1999 being the commonest decade. Articles were cited on average 4.6 times per year. Articles were published in 28 different journals, with impact factors ranging from 0.94 to 35.3. Most articles were observational research studies. These findings reflect the attention that articles have received during the past half century in oral and maxillofacial trauma research, shedding light on often-read articles in this field. In addition to current bibliometric indices, it could provide a useful evidence base for facial surgeons, represent key educational material for aspiring trainees, and be used to help guide future research efforts.

    Carnahan, Ryan M; Kee, Vicki R

    2012-01-01

    This paper aimed to systematically review algorithms to identify transfusion-related ABO incompatibility reactions in administrative data, with a focus on studies that have examined the validity of the algorithms. A literature search was conducted using PubMed, Iowa Drug Information Service database, and Embase. A Google Scholar search was also conducted because of the difficulty identifying relevant studies. Reviews were conducted by two investigators to identify studies using data sources from the USA or Canada because these data sources were most likely to reflect the coding practices of Mini-Sentinel data sources. One study was found that validated International Classification of Diseases (ICD-9-CM) codes representing transfusion reactions. None of these cases were ABO incompatibility reactions. Several studies consistently used ICD-9-CM code 999.6, which represents ABO incompatibility reactions, and a technical report identified the ICD-10 code for these reactions. One study included the E-code E8760 for mismatched blood in transfusion in the algorithm. Another study reported finding no ABO incompatibility reaction codes in the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database, which contains data of 2.23 million patients who received transfusions, raising questions about the sensitivity of administrative data for identifying such reactions. Two studies reported perfect specificity, with sensitivity ranging from 21% to 83%, for the code identifying allogeneic red blood cell transfusions in hospitalized patients. There is no information to assess the validity of algorithms to identify transfusion-related ABO incompatibility reactions. Further information on the validity of algorithms to identify transfusions would also be useful. Copyright © 2012 John Wiley & Sons, Ltd.

    During the last decades, sex and gender biases have been identified in various areas of biomedical and public health research, leading to compromised validity of research findings. As a response, methodological requirements were developed but these are rarely translated into research practice. The aim of this study is to provide good practice examples of sex/gender sensitive health research. We conducted a systematic search of research articles published in JECH between 2006 and 2014. An instrument was constructed to evaluate sex/gender sensitivity in four stages of the research process (background, study design, statistical analysis, discussion). In total, 37 articles covering diverse topics were included. Thereof, 22 were evaluated as good practice example in at least one stage; two articles achieved highest ratings across all stages. Good examples of the background referred to available knowledge on sex/gender differences and sex/gender informed theoretical frameworks. Related to the study design, good examples calculated sample sizes to be able to detect sex/gender differences, selected sex/gender sensitive outcome/exposure indicators, or chose different cut-off values for male and female participants. Good examples of statistical analyses used interaction terms with sex/gender or different shapes of the estimated relationship for men and women. Examples of good discussions interpreted their findings related to social and biological explanatory models or questioned the statistical methods used to detect sex/gender differences. The identified good practice examples may inspire researchers to critically reflect on the relevance of sex/gender issues of their studies and help them to translate methodological recommendations of sex/gender sensitivity into research practice.

  15. BreakingNews: Article Annotation by Image and Text Processing.

    PubMed

    2018-05-01

    Building upon recent Deep Neural Network architectures, current approaches lying in the intersection of Computer Vision and Natural Language Processing have achieved unprecedented breakthroughs in tasks like automatic captioning or image retrieval. Most of these learning methods, though, rely on large training sets of images associated with human annotations that specifically describe the visual content. In this paper we propose to go a step further and explore the more complex cases where textual descriptions are loosely related to the images. We focus on the particular domain of news articles in which the textual content often expresses connotative and ambiguous relations that are only suggested but not directly inferred from images. We introduce an adaptive CNN architecture that shares most of the structure for multiple tasks including source detection, article illustration and geolocation of articles. Deep Canonical Correlation Analysis is deployed for article illustration, and a new loss function based on Great Circle Distance is proposed for geolocation. Furthermore, we present BreakingNews, a novel dataset with approximately 100K news articles including images, text and captions, and enriched with heterogeneous meta-data (such as GPS coordinates and user comments). We show this dataset to be appropriate to explore all aforementioned problems, for which we provide a baseline performance using various Deep Learning architectures, and different representations of the textual and visual features. We report very promising results and bring to light several limitations of current state-of-the-art in this kind of domain, which we hope will help spur progress in the field.

    2009-01-01

    PubMed is the most widely used tool for searching biomedical literature online. As with many other online search tools, a user often types a series of multiple related queries before retrieving satisfactory results to fulfill a single information need. Meanwhile, it is also a common phenomenon to see a user type queries on unrelated topics in a single session. In order to study PubMed users’ search strategies, it is necessary to be able to automatically separate unrelated queries and group together related queries. Here, we report a novel approach combining both lexical and contextual analyses for segmenting PubMed query sessions and identifying related queries and compare its performance with the previous approach based solely on concept mapping. We experimented with our integrated approach on sample data consisting of 1,539 pairs of consecutive user queries in 351 user sessions. The prediction results of 1,396 pairs agreed with the gold-standard annotations, achieving an overall accuracy of 90.7%. This demonstrates that our approach is significantly better than the previously published method. By applying this approach to a one day query log of PubMed, we found that a significant proportion of information needs involved more than one PubMed query, and that most of the consecutive queries for the same information need are lexically related. Finally, the proposed PubMed distance is shown to be an accurate and meaningful measure for determining the contextual similarity between biological terms. The integrated approach can play a critical role in handling real-world PubMed query log data as is demonstrated in our experiments. PMID:19162232

    Background: Several studies have analyzed the most cited articles in shoulder, elbow, pediatrics, and foot and ankle surgery. However, no study has analyzed the quality of the most cited articles in elbow medial ulnar collateral ligament (UCL) surgery. Purpose: To (1) identify the top 50 most cited articles related to UCL surgery, (2) determine whether there was a correlation between the top cited articles and level of evidence, and (3) determine whether there was a correlation between study methodological quality and the top cited articles. Study Design: Systematic review. Methods: Web of Science and Scopus online databases were searched to identify the top 50 cited articles in UCL surgery. Level of evidence, number of times cited, year of publication, name of journal, country of origin, and study type were recorded for each study. Study methodological quality was analyzed for each article with the Modified Coleman Methodology Score (MCMS) and the Methodological Index for Non-randomized Studies (MINORS). Correlation coefficients were calculated. Results: The 50 most cited articles were published between 1981 and 2015. The number of citations per article ranged from 20 to 301 (mean ± SD, 71 ± 62 citations). Most articles (92%) were from the United States and were level 3 (16%), level 4 (58%), or unclassified (16%) evidence. There were no articles of level 1 evidence quality. The mean MCMS and MINORS scores were 28.1 ± 13.4 (range, 3-52) and 9.2 ± 3.6 (range, 2-19), respectively. There was no significant correlation between the mean number of citations and level of evidence or quality (rs = –0.01, P = .917), MCMS (rs = 0.09, P = .571), or MINORS (rs = –0.26, P = .089). Conclusion: The top 50 cited articles in UCL surgery constitute a low level of evidence and low methodological quality, including no level 1 articles. There was no significant correlation between the mean number of citations and level of evidence or study methodological quality. However, weak

    Five near full-length genomes of novel second-generation HIV-1 recombinant virus (JS150021, JS150029, JS150129, JS150132, and AH150183) were identified from five HIV-positive people in Jiangsu and Anhui province, east China. Phylogenic analyses showed that these five sequences are all composed of two well-established circulating recombinant forms (CRFs) CRF07_BC and CRF01_AE, grouped into four new discovered recombinant forms, which show several very similar but not identical recombinant breakpoints. The four recombinant forms are also identified to be a sort of family or related viruses, seems to be the results of different recombination events. The emergence of a serious new closely related CRF07_BC/CRF01_AE recombinant strain indicates the increasing complexity of sexual transmission of the HIV-1 epidemic in China.

    An element of health technology assessment constitutes assessing the clinical effectiveness of drugs, generally called relative effectiveness assessment. Little real-world evidence is available directly after market access, therefore randomized controlled trials are used to obtain information for relative effectiveness assessment. However, there is growing interest in using real-world data for relative effectiveness assessment. Social media may provide a source of real-world data. We assessed the extent to which social media-generated health data has provided insights for relative effectiveness assessment. An explorative literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify examples in oncology where health data were collected using social media. Scientific and grey literature published between January 2010 and June 2016 was identified by four reviewers, who independently screened studies for eligibility and extracted data. A descriptive qualitative analysis was performed. Of 1032 articles identified, eight were included: four articles identified adverse events in response to cancer treatment, three articles disseminated quality of life surveys, and one study assessed the occurrence of disease-specific symptoms. Several strengths of social media-generated health data were highlighted in the articles, such as efficient collection of patient experiences and recruiting patients with rare diseases. Conversely, limitations included validation of authenticity and presence of information and selection bias. Social media may provide a potential source of real-world data for relative effectiveness assessment, particularly on aspects such as adverse events, symptom occurrence, quality of life, and adherence behavior. This potential has not yet been fully realized and the degree of usefulness for relative effectiveness assessment should be further explored. ©Rachel R.J. Kalf, Amr Makady, Renske

    Unlike most online social networks where explicit links among individual users are defined, the relations among commercial entities (e.g. firms) may not be explicitly declared in commercial Web sites. One main contribution of this article is the development of a novel computational model for the discovery of the latent relations among commercial entities from online financial news. More specifically, a CRF model which can exploit both structural and contextual features is applied to commercial entity recognition. In addition, a point-wise mutual information (PMI)-based unsupervised learning method is developed for commercial relation identification. To evaluate the effectiveness of the proposed computational methods, a prototype system called CoNet has been developed. Based on the financial news articles crawled from Google finance, the CoNet system achieves average F-scores of 0.681 and 0.754 in commercial entity recognition and commercial relation identification, respectively. Our experimental results confirm that the proposed shallow natural language processing methods are effective for the discovery of latent commercial networks from online financial news.

    The purpose of this study was to identify and review the most cited articles in the occupational therapy field. Using the multi-disciplinary Publish or Perish software to extract data, the top 50 lifetime and annual cited articles were examined. Studies were organized according to the following: year of publication, design, topic, number of authors, country of publication, and number of citations for each cohort. We found that randomized control trials were the dominant design type used in papers with the most lifetime (36.0%) and annual (26.0%) citations. Additionally, in both groups, the most frequently cited articles investigated predictors of functional outcome for patients. This comprehensive citation analysis will inform future research through its identification of major trends and well-established areas of study.

    Relational frame theory (RFT) is a contemporary behavior-analytic account of language and cognition. Since it was first outlined in 1985, RFT has generated considerable controversy and debate, and several claims have been made concerning its evidence base. The present study sought to evaluate the evidence base for RFT by undertaking a citation analysis and by categorizing all articles that cited RFT-related search terms. A total of 174 articles were identified between 1991 and 2008, 62 (36%) of which were empirical and 112 (64%) were nonempirical articles. Further analyses revealed that 42 (68%) of the empirical articles were classified as empirical RFT and 20 (32%) as empirical other, whereas 27 (24%) of the nonempirical articles were assigned to the nonempirical reviews category and 85 (76%) to the nonempirical conceptual category. In addition, the present findings show that the majority of empirical research on RFT has been conducted with typically developing adult populations, on the relational frame of sameness, and has tended to be published in either The Psychological Record or the Journal of the Experimental Analysis of Behavior. Overall, RFT has made a substantial contribution to the literature in a relatively short period of time.

    2017-04-01

    The aims of this study were to identify characteristics of the top-cited articles in problem-based learning (PBL) and assess the quality of evidence provided by these articles. The most frequently cited articles on PBL were searched in April 2015 in the Science Citation Index Expanded database (List A) and Google Scholar database (List B). Eligible articles identified were reviewed for key characteristics. The Oxford Centre for Evidence-Based Medicine guidelines were used in assessing the level of evidence. The number of citations varied (62 to 923 on List A and 218 to 2,859 on List B). Countries that contributed the majority of articles in both lists were the United States, Netherlands, United Kingdom, and Canada. No significant correlations were found between number of citations and number of years since published (p=0.451), number of authors (p=0.144), females in authorship (p=0.189), non-medical authors (p=0.869), number of institutions (p=0.452), and number of grants (p=0.143), but a strong correlation was found with number of countries involved (p=0.007). Application of the Oxford hierarchy of evidence showed that 36 articles were at levels 4 and 5 of evidence. This study found that research articles represented approximately one-third of PBL articles assessed and reported mainly on questionnaire-based studies. The most highly cited articles occupied top-ranking positions in the journals in which they were published. The lower level of evidence observed in most top-cited articles may reflect the significance of innovative ideas or content of these articles. These findings have implications for dental educators and dental researchers.

    Background Video games provide extensive player involvement for large numbers of children and adults, and thereby provide a channel for delivering health behavior change experiences and messages in an engaging and entertaining format. Method Twenty-seven articles were identified on 25 video games that promoted health-related behavior change through December 2006. Results Most of the articles demonstrated positive health-related changes from playing the video games. Variability in what was reported about the games and measures employed precluded systematically relating characteristics of the games to outcomes. Many of these games merged the immersive, attention-maintaining properties of stories and fantasy, the engaging properties of interactivity, and behavior-change technology (e.g., tailored messages, goal setting). Stories in video games allow for modeling, vicarious identifying experiences, and learning a story’s “moral,” among other change possibilities. Conclusions Research is needed on the optimal use of game-based stories, fantasy, interactivity, and behavior change technology in promoting health-related behavior change. PMID:18083454

    Objective: To analyze the current status of epidemiological study of burns in China, and to explore the related strategies. Methods: Retrospective or cross-sectional scientific articles in Chinese or English on epidemiological study of burns in China published from January 2005 to December 2015 were systemically retrieved from 4 databases. The databases include PubMed, Embase, China Biology Medicine disc, and Chinese Journals Full - text Database . From the results retrieved, data with regard to publication year, journal distribution, number of institutions participated in the study, affiliation of the first author and its location, and admission time span and age of patients in all the scientific articles were collected. Furthermore, the definition of age range and the grouping method of age of pediatric patients in English articles on epidemiological study of pediatric burns of China were recorded. Data were processed with descriptive statistical analysis. Results: A total of 256 scientific articles conforming to the study criteria were retrieved, among which 214 (83.59%) articles were in Chinese, and 42 (16.41%) articles were in English; 242 (94.53%) articles were retrospective studies, and 14 (5.47%) articles were cross-sectional studies. During the 11 years, the number of the relevant articles was fluctuant on the whole. The scientific articles were published in 130 journals, with 42 English articles in source journals for SCIENCE CITATION INDEX EXPANDED - JOURNAL LIST, accounting for 16.41%, and 116 Chinese articles in Source Journal for Chinese Scientific and Technical Papers, accounting for 45.31%. Totally 215 (83.98%) articles were single-center studies, and 29 (11.33%) articles were multicenter studies which were conducted by three or more centers. The number of affiliations of the first author of articles was 161 in total. The top 10 institutions regarding the article publishing number published 58 articles, accounting for 22.66%.

    Many text mining applications in the biomedical domain benefit from automatic clustering of relational phrases into synonymous groups, since it alleviates the problem of spurious mismatches caused by the diversity of natural language expressions. Most of the previous work that has addressed this task of synonymy resolution uses similarity metrics between relational phrases based on textual strings or dependency paths, which, for the most part, ignore the context around the relations. To overcome this shortcoming, we employ a word embedding technique to encode relational phrases. We then apply the k-means algorithm on top of the distributional representations to cluster the phrases. Our experimental results show that this approach outperforms state-of-the-art statistical models including latent Dirichlet allocation and Markov logic networks. Copyright © 2015 Elsevier Inc.

    This study was designed to locate and document serial literature on occupational therapy published since 1900. Emphasis is placed on finding articles on occupational therapy or by occupational therapists from sources other than those normally associated with the professional journals. Multiple sources were used including print indexes, online databases, occupational therapy bibliographies, and tables of contents or yearly indexes. Almost 7,000 articles were identified, not including those published in foreign journals. Occupational therapy publications have increased steadily since 1900, with the most rapid increase during the 1970s and 1980s when five new occupational therapy journals were initiated. Suggestions for formulating search strategies are included. PMID:3285932

  11. Identifying and Describing the Impact of Cyclone, Storm and Flood Related Disasters on Treatment Management, Care and Exacerbations of Non-communicable Diseases and the Implications for Public Health.

    Over the last quarter of a century the frequency of natural disasters and the burden of non-communicable diseases (NCD) across the globe have been increasing. For individuals susceptible to, or chronically experiencing, NCDs this has become a significant risk. Disasters jeopardize access to essential treatment, care, equipment, water and food, which can result in an exacerbation of existing conditions or even preventable death. Consequently, there is a need to expand the public health focus of disaster management to include NCDs. To provide a platform for this to occur, this article presents the results from a systematic review that identifies and describes the impact of cyclone, flood and storm related disasters on those susceptible to, or experiencing, NCDs. The NCDs researched were: cardiovascular diseases; cancers; chronic respiratory diseases; and diabetes.   Four electronic publication databases were searched with a date limit of 31 December 2014. The data was analyzed through an aggregation of individual papers to create an overall data description. The data was then grouped by disease to describe the impact of a disaster on treatment management, exacerbation, and health care of people with NCDs. The PRISMA checklist was used to guide presentation of the research.   The review identified 48 relevant articles. All studies represented developed country data. Disasters interrupt treatment management and overall care for people with NCDs, which results in an increased risk of exacerbation of their illness or even death. The interruption may be caused by a range of factors, such as damaged transport routes, reduced health services, loss of power and evacuations. The health impact varied according to the NCD. For people with chronic respiratory diseases, a disaster increases the risk of acute exacerbation. Meanwhile, for people with cancer, cardiovascular diseases and diabetes there is an increased risk of their illness exacerbating, which can result in death

    2015-01-01

    Background The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited papers may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997–2007. Methods and Results We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997–2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164,377 articles in 222 cardiovascular journals from 1997–2007. From 1997–2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2% respectively. Of all the articles, 75,550 (46.0%) were poorly cited, of which 25,650 (15.6% overall) had no citations. From 1997–2007, the proportion of poorly cited articles declined slightly (52.1% to 46.2%, trend P<0.001), although the absolute number of poorly cited articles increased by 2,595 (trend P<0.001). At a journal level, 44% of cardiovascular journals had more than three quarters of the journal’s content poorly cited at 5 years. Conclusion Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature, and the number of poorly cited articles, have both increased substantially from 1997–2007. The high proportion of poorly cited articles and journals suggest inefficiencies in the cardiovascular research enterprise. PMID:25812573

    Childhood cancer survivors often experience complications related to cancer and its treatment that may adversely affect quality of life and increase the risk of premature death. The purpose of this manuscript is to review how data derived from Childhood Cancer Survivor Study (CCSS) investigations have facilitated identification of childhood cancer survivor populations at high risk for specific organ toxicity and secondary carcinogenesis and how this has informed clinical screening practices. Articles previously published that used the resource of the CCSS to identify risk factors for specific organ toxicity and subsequent cancers were reviewed and results summarized. CCSS investigations have characterized specific groups to be at highest risk of morbidity related to endocrine and reproductive dysfunction, pulmonary toxicity, cerebrovascular injury, neurologic and neurosensory sequelae, and subsequent neoplasms. Factors influencing risk for specific outcomes related to the individual survivor (eg, sex, race/ethnicity, age at diagnosis, attained age), sociodemographic status (eg, education, household income, health insurance) and cancer history (eg, diagnosis, treatment, time from diagnosis) have been consistently identified. These CCSS investigations that clarify risk for treatment complications related to specific treatment modalities, cumulative dose exposures, and sociodemographic factors identify profiles of survivors at high risk for cancer-related morbidity who deserve heightened surveillance to optimize outcomes after treatment for childhood cancer.

    To determine the effectiveness of an index in increasing recognition of misleading problem framing in articles and manuscripts. A propaganda index consisting of 32 items was developed drawing on related literature. Seventeen subjects who review manuscripts for possible publication were requested to read five recent published reports of randomized controlled trials concerning social anxiety and to identify indicators of propaganda (defined as encouraging beliefs and actions with the least thought possible). They then re-read the same five articles using a propaganda index to note instances of propaganda. Convenience sample of individuals who review manuscripts for possible publication and sample of recent published reports of randomized controlled trials regarding social anxiety in five different journals by different authors, blinded by author and journal. Data showed that there was a high rate of propagandistic problem framing in reports of RCTs regarding social anxiety such as hiding well argued alternative views and vagueness. This occurred in 117 out of 160 opportunities over five research reports. A convenience sample of 17 academics spotted only 4.5 percent of propaganda indicators. This increased to 64 percent with use of the 32 item propaganda index. Use of a propaganda index increased recognition of related indicators. However many instances remained undetected. This propaganda index warrants further exploration as a complement to reporting guidelines such as CONSORT and PRISMA.

    Headache is one of the most frequently encountered neurological symptoms during hemodialysis. According to International Classification of Headache criteria dialysis-related headache was defined as the headache occurring during hemodialysis with no specific characteristic. It resolves spontaneously within 72 hours after the hemodialysis session ends. There are few studies in the literature investigating the clinical features of dialysis headache. The pathophysiology of hemodialysis-related headache is not known, but various triggering factors have been identified, including changes in blood pressure, serum sodium and magnesium levels during hemodialysis sessions, caffeine deprivation and stress. The aim of this article is to evaluate and analyze features of headache in patients undergoing hemodialysis. © 2014 International Society for Hemodialysis.

    Sarcoidosis is a multifactorial systemic disease characterized by granulomatous inflammation and greatly impacting on global public health. The etiology and mechanisms of sarcoidosis are not fully understood. Recent high-throughput biological research has generated vast amounts of multi-omics big data on sarcoidosis, but their significance remains to be determined. We sought to identify novel candidate regions, and genes consistently altered in heterogeneous omics studies so as to reveal the underlying molecular mechanisms. We conducted a comprehensive integrative literature analysis on global data on sarcoidosis, including genomic, transcriptomic, proteomic, and phenomic studies. We performed positional integration analysis of 38 eligible datasets originating from 17 different biological layers. Using the integration interval length of 50 kb, we identified 54 regions reaching significance value p ≤ 0.0001 and 15 regions with significance value p ≤ 0.00001, when applying more stringent criteria. Secondary literature analysis of the top 20 regions, with the most significant accumulation of signals, revealed several novel candidate genes for which associations with sarcoidosis have not yet been established, but have considerable support for their involvement based on omic data. These new plausible candidate genes include NELFE, CFB, EGFL7, AGPAT2, FKBPL, NRC3, and NEU1. Furthermore, annotated data were prepared to enable custom visualization and browsing of these sarcoidosis related omics evidence in the University of California Santa Cruz (UCSC) Genome Browser. Further multi-omics approaches are called for sarcoidosis biomarkers and diagnostic and therapeutic innovation. Our approach for harnessing multi-omics data and the findings presented herein reflect important steps toward understanding the etiology and underlying pathological mechanisms of sarcoidosis.

    2018-02-01

    Peer-review is an essential activity for the vast majority of credited scientific journals and represents the cornerstone for assessing the quality of potential publications, since it is substantially aimed to identify drawbacks or inaccuracies that may flaw the outcome or the presentation of scientific research. Since the importance of this activity is seldom underestimated by some referees, the purpose of this article is to present a personal and arbitrary perspective on how a scientific article should be peer-reviewed, offering a tentative checklist aimed to describe the most important criteria that should be considered. These basically include accepting the assignment only when the topic is in accordance with referee's background, disclosing potential conflicts of interest, checking availability and time according to size and complexity of the article, identifying the innovative value of the manuscript, providing exhaustive and clear comments, expressing disagreement with a fair and balanced approach, weighting revisions according to the importance of the journal, summarizing recommendations according to previous comments, maintaining confidentiality throughout and after the peer-review process.

    A method of drying a green particulate article includes the steps of: a. Providing a green article which includes a particulate material and a pore phase material, the pore phase material including a solvent; and b. contacting the green article with a liquid desiccant for a period of time sufficient to remove at least a portion of the solvent from the green article, the pore phase material acting as a semipermeable barrier to allow the solvent to be sorbed into the liquid desiccant, the pore phase material substantially preventing the liquid desiccant from entering the pores.

    Background To practice evidence-based medicine, physicians should have a solid understanding of fundamental epidemiological and biostatistical concepts. Research suggests that only a minority of physicians have such an understanding of biostatistics. Objective To collect pilot data on a novel biostatistical educational tool, a hyperlink-embedded journal article, which is aimed at improving knowledge in biostatistics. Methods Forty-four physicians-in-training participated in this pilot study. Participants completed a pretest consisting of 5 questions about biostatistical terms that would be encountered in the article. They were randomized to either an unmodified journal article or to the same article with hyperlinked biostatistical terms. All participants then completed a posttest that was identical to the pretest. Results Having access to hyperlinked information had a positive association with the number of improved test answers (P = .05). Use of hyperlinks varied, and were seemingly dependent on user comfort with terms; well-understood definitions (“average”) were clicked on a few times (5.5% of participants), whereas more obscure method terms (“Lexis diagram”) were clicked on by 94% of participants. While only 42% of participants stated they would have looked up definitions of the biostatistical terms if they had not been provided in the hyperlinked article, 94% of participants identified the hyperlink tool as something they would use if readily available to them when reading journal articles. Conclusions Results of this pilot study of a novel educational intervention suggest that embedded hyperlinks within journal articles may be a useful tool to teach biostatistical terms to physicians.

    Interprofessional education (IPE) aspires to enable collaborative practice. Current IPE offerings, although rapidly proliferating, lack evidence of efficacy and theoretical grounding. Our research aimed to explore the historical emergence of the field of IPE and to analyse the positioning of this academic field of inquiry. In particular, we sought to investigate the extent to which power and conflict - elements central to interprofessional care - figure in the IPE literature. We used a combination of deductive and inductive automated coding and manual coding to explore the contents of 2191 articles in the IPE literature published between 1954 and 2013. Inductive coding focused on the presence and use of the sociological (rather than statistical) version of power, which refers to hierarchies and asymmetries among the professions. Articles found to be centrally about power were then analysed using content analysis. Publications on IPE have grown exponentially in the past decade. Deductive coding of identified articles showed an emphasis on students, learning, programmes and practice. Automated inductive coding of titles and abstracts identified 129 articles potentially about power, but manual coding found that only six articles put power and conflict at the centre. Content analysis of these six articles revealed that two provided tentative explorations of power dynamics, one skirted around this issue, and three explicitly theorised and integrated power and conflict. The lack of attention to power and conflict in the IPE literature suggests that many educators do not foreground these issues. Education programmes are expected to transform individuals into effective collaborators, without heed to structural, organisational and institutional factors. In so doing, current constructions of IPE veil the problems that IPE attempts to solve. © 2015 The Authors Medical Education Published by John Wiley & Sons Ltd.

  3. Burnout in Relation to Specific Contributing Factors and Health Outcomes among Nurses: A Systematic Review

    2013-01-01

    Nurses have been found to experience higher levels of stress-related burnout compared to other health care professionals. Despite studies showing that both job satisfaction and burnout are effects of exposure to stressful working environments, leading to poor health among nurses, little is known about the causal nature and direction of these relationships. The aim of this systematic review is to identify published research that has formally investigated relationships between these variables. Six databases (including CINAHL, COCHRANE, EMBASE, MEDLINE, PROQUEST and PsyINFO) were searched for combinations of keywords, a manual search was conducted and an independent reviewer was asked to cross validate all the electronically identified articles. Of the eighty five articles that were identified from these databases, twenty one articles were excluded based on exclusion criteria; hence, a total of seventy articles were included in the study sample. The majority of identified studies exploring two and three way relationships (n = 63) were conducted in developed countries. Existing research includes predominantly cross-sectional studies (n = 68) with only a few longitudinal studies (n = 2); hence, the evidence base for causality is still very limited. Despite minimal availability of research concerning the small number of studies to investigate the relationships between work-related stress, burnout, job satisfaction and the general health of nurses, this review has identified some contradictory evidence for the role of job satisfaction. This emphasizes the need for further research towards understanding causality. PMID:23727902

    Background Diagnostic errors (missed, delayed, or wrong diagnosis) have gained recent attention and are associated with significant preventable morbidity and mortality. We reviewed the recent literature to identify interventions that have been, or could be, implemented to address systems-related factors that contribute directly to diagnostic error. Methods We conducted a comprehensive search using multiple search strategies. We first identified candidate articles in English between 2000 and 2009 from a PubMed search that exclusively evaluated for articles related to diagnostic error or delay. We then sought additional papers from references in the initial dataset, searches of additional databases, and subject matter experts. Articles were included if they formally evaluated an intervention to prevent or reduce diagnostic error; however, we also included papers if interventions were suggested and not tested in order to inform the state-of-the science on the topic. We categorized interventions according to the step in the diagnostic process they targeted: patient-provider encounter, performance and interpretation of diagnostic tests, follow-up and tracking of diagnostic information, subspecialty and referral-related; and patient-specific. Results We identified 43 articles for full review, of which 6 reported tested interventions and 37 contained suggestions for possible interventions. Empirical studies, though somewhat positive, were non-experimental or quasi-experimental and included a small number of clinicians or health care sites. Outcome measures in general were underdeveloped and varied markedly between studies, depending on the setting or step in the diagnostic process involved. Conclusions Despite a number of suggested interventions in the literature, few empirical studies have tested interventions to reduce diagnostic error in the last decade. Advancing the science of diagnostic error prevention will require more robust study designs and rigorous definitions

    Understanding the etiology of cancer-related fatigue (CRF) is critical to identify targets to develop therapies to reduce CRF burden. The goal of this systematic review was to expand on the initial work by the National Cancer Institute CRF Working Group to understand the state of the science related to the biology of CRF and, specifically, to evaluate studies that examined the relationships between biomarkers and CRF and to develop an etiologic model of CRF to guide researchers on pathways to explore or therapeutic targets to investigate. This review was completed by the Multinational Association of Supportive Care in Cancer Fatigue Study Group-Biomarker Working Group. The initial search used three terms (biomarkers, fatigue, cancer), which yielded 11,129 articles. After removing duplicates, 9145 articles remained. Titles were assessed for the keywords "cancer" and "fatigue" resulting in 3811 articles. Articles published before 2010 and those with samples <50 were excluded, leaving 75 articles for full-text review. Of the 75 articles, 28 were further excluded for not investigating the associations of biomarkers and CRF. Of the 47 articles reviewed, 25 were cross-sectional and 22 were longitudinal studies. More than half (about 70 %) were published recently (2010-2013). Almost half (45 %) enrolled breast cancer participants. The majority of studies assessed fatigue using self-report questionnaires, and only two studies used clinical parameters to measure fatigue. The findings from this review suggest that CRF is linked to immune/inflammatory, metabolic, neuroendocrine, and genetic biomarkers. We also identified gaps in knowledge and made recommendations for future research.

    Fatalities in boxing are most often due to traumatic brain injury that occurs in the ring. In the past 30 years, significant improvements in ringside and medical equipment, safety, and regulations have resulted in a dramatic reduction in the fatality rate. Nonetheless, the rate of boxing-related head injuries, particularly concussions, remains unknown, due in large part to its variability in clinical presentation. Furthermore, the significance of repeat concussions sustained when boxing is just now being understood. In this article, we identify the clinical manifestations, pathophysiology, and management of boxing-related head injuries, and discuss preventive strategies to reduce head injuries sustained by boxers.

    Background: Phylogenetic footprinting has revealed that cis-regulatory enhancers consist of conserved DNA sequence clusters (CSCs). Currently, there is no systematic approach for enhancer discovery and analysis that takes full-advantage of the sequence information within enhancer CSCs. Results: We have generated a Drosophila genome-wide database of conserved DNA consisting of >100,000 CSCs derived from EvoPrints spanning over 90% of the genome. cis-Decoder database search and alignment algorithms enable the discovery of functionally related enhancers. The program first identifies conserved repeat elements within an input enhancer and then searches the database for CSCs that score highly against the input CSC. Scoring is based on shared repeats as well as uniquely shared matches, and includes measures of the balance of shared elements, a diagnostic that has proven to be useful in predicting cis-regulatory function. To demonstrate the utility of these tools, a temporally-restricted CNS neuroblast enhancer was used to identify other functionally related enhancers and analyze their structural organization. Conclusions: cis-Decoder reveals that co-regulating enhancers consist of combinations of overlapping shared sequence elements, providing insights into the mode of integration of multiple regulating transcription factors. The database and accompanying algorithms should prove useful in the discovery and analysis of enhancers involved in any developmental process.

    2018-05-16

    The recognition of occupational carcinogens is important for primary prevention, compensation and surveillance of exposed workers, as well as identifying causes of cancer in the general population. This study updates previously published lists of known occupational carcinogens while providing additional information on cancer type, exposure scenarios and routes, and discussing trends in the identification of carcinogens over time. Data were extracted from International Agency for Research on Cancer (IARC) Monographs covering the years 1971-2017, using specific criteria to ensure occupational relevance and provide high confidence in the causality of observed exposure-disease associations. Selected agents were substances, mixtures or types of radiation classified in IARC Group 1 with 'sufficient evidence of carcinogenicity' in humans from studies of exposed workers and evidence of occupational exposure documented in the pertinent monograph. The number of known occupational carcinogens has increased over time: 47 agents were identified as known occupational carcinogens in 2017 compared with 28 in 2004. These estimates are conservative and likely underestimate the number of carcinogenic agents present in workplaces. Exposure to these agents causes a wide range of cancers; cancers of the lung and other respiratory sites, followed by skin, account for the largest proportion. The dominant routes of exposure are inhalation and dermal contact. Important progress has been made in identifying occupational carcinogens; nevertheless, there is an ongoing need for research on the causes of work-related cancer. Most workplace exposures have not been evaluated for their carcinogenic potential due to inadequate epidemiologic evidence and a paucity of quantitative exposure data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To evaluate and compare the characteristics of the most downloaded and most cited articles in radiology journals. We selected 41 radiology journals that provided lists of both the most downloaded and most cited articles on their websites, and identified the 596 most downloaded articles and 596 most cited articles. We compared the following characteristics of the most downloaded and most cited articles: year of publication, journal title, department of the first author, country of origin, publication type, radiologic subspecialty, radiologic technique and accessibility. Compared to the most cited articles, the most downloaded articles were more frequently review articles (36.1% vs 17.1%, p < 0.05), case reports (5.9% vs 3.2%, p < 0.05), guidelines/consensus statements (5.4% vs 2.7%, p < 0.05), editorials/commentaries (3.7% vs 0.7%, p < 0.05) and pictorial essays (2.0% vs 0.2%, p < 0.05). Compared to the most cited articles, the most downloaded articles more frequently originated from the UK (8.7% vs 5.0%, p < 0.05) and were more frequently free-access articles (46.0% vs 39.4%, p < 0.05). Educational and free-access articles are more frequent among the most downloaded articles. • There was only small overlap between the most downloaded and most cited articles. • Educational articles were more frequent among the most downloaded articles. • Free-access articles are more frequent among the most downloaded articles.

    Qualitative comparative analysis (QCA) was developed over 25 years ago to bridge the qualitative and quantitative research gap. Upon searching PubMed and the Journal of Mixed Methods Research , this review identified 30 original research studies that utilized QCA. Perceptions that QCA is complex and provides few relative advantages over other methods may be limiting QCA adoption. Thus, to overcome these perceptions, this article demonstrates how to perform QCA using data from fifteen institutions that implemented universal tumor screening (UTS) programs to identify patients at high risk for hereditary colorectal cancer. In this example, QCA revealed a combination of conditions unique to effective UTS programs. Results informed additional research and provided a model for improving patient follow-through after a positive screen.

    already malnourished and those who are at risk of malnourishment. Studies went on to examine the effectiveness of health care workers (nurses and doctors) with a knowledge base focused on clinical care and their ability to accurately and consistently identify malnourished geriatric patients within that setting. Most articles reported effectiveness in accurately increasing malnutrition detection and awareness. Computerized tools and apps may also help reduce health care workers' workload and time spent assessing patients for malnutrition. Hospitals may also benefit from implementing malnutrition technology through observing decreased length of stay, along with decreased foregone costs related to missing malnutrition diagnoses. It is beneficial to study the impact of these technologies to examine possible areas of improvement. A future systematic review would further contribute to the evidence and effectiveness of the use of technologies in assessing and monitoring hospital malnutrition. ©Dino Trtovac, Joon Lee.

    Citation analyses aid in assessing quality, trends and future directions of research fields. To identify the most influential articles on infections caused by non-tuberculous mycobacteria (NTM) in the last 20 years. We performed a cited reference search of the Web of Science database from 1995 to 2015. The 100 most cited articles on NTM infections were analysed. The top 100 articles were cited 114-1471 times, and were published from 1995 to 2013. Sixty-five were laboratory-based, basic science articles, with the major topics being pathophysiology (n = 20) and molecular methods for NTM identification (n = 15). Among the 35 non-laboratory studies, major topics were clinical management (n = 15) and epidemiology (n = 14). The top article was a clinical treatise on the management of NTM disease, published in 2007. Although there was a correlation between article rank and journal impact factor (P = 0.043, ρ = -0.202), the five articles from the journals with highest impact factors did not rank among the top 10 articles. A large proportion of influential articles on NTM infection are basic scientific studies, and the most influential articles are not always published in high-impact journals.

    Quality control for stitching of a textile article is performed by measuring thread tension in the stitches as the stitches are being made, determining locations of the stitches, and generating a map including the locations and stitching data derived from the measured thread tensions. The stitching data can be analyzed, off-line or in real time, to identify defective stitches. Defective stitches can then be repaired. Real time analysis of the thread tensions allows problems such as broken needle threads to be corrected immediately.

    Obesity is the second leading cause of preventable death in the United States. However, physicians feel poorly trained to address the obesity epidemic. This article examines effective training methods for overweight and obesity intervention in undergraduate medical education. Using indexing terms related to overweight, obesity, and medical student education, we conducted a literature searched PubMed PsycINFO, Cochrane, and ERIC for relevant articles in English. References from articles identified were also reviewed to located additional articles. We included all studies that incorporated process or outcome evaluations of obesity educational interventions for U.S. medical students. Of an initial 168 citations, 40 abstracts were retrieved; 11 studies were found to be pertinent to medical student obesity education, but only 5 included intervention and evaluation elements. Quality criteria for inclusion consisted of explicit evaluation of the educational methods used. Data extraction identified participants (e.g., year of medical students), interventions, evaluations, and results. These 5 studies successfully used a variety of teaching methods including hands on training, didactic lectures, role-playing, and standardized patient interaction to increase medical students' knowledge, attitudes, and skills regarding overweight and obesity intervention. Two studies addressed medical student bias toward overweight and obese patients. No studies addressed health disparities in the epidemiology and bias of obesity. Despite the commonly cited "obesity epidemic," there are very few published studies that report the effectiveness of medical school obesity educational programs. Gaps still exist within undergraduate medical education including specific training that addresses obesity and long-term studies showing that such training is retained.

  6. Identifying translational science within the triangle of biomedicine.

    The National Institutes of Health (NIH) Roadmap places special emphasis on "bench-to-bedside" research, or the "translation" of basic science research into practical clinical applications. The Clinical and Translational Science Awards (CTSA) Consortium is one example of the large investments being made to develop a national infrastructure to support translational science, which involves reducing regulatory burdens, launching new educational initiatives, and forming partnerships between academia and industry. However, while numerous definitions have been suggested for translational science, including the qualitative T1-T4 classification, a consensus has not yet been reached. This makes it challenging to tract the impact of these major policy changes. In this study, we use a bibliometric approach to map PubMed articles onto a graph, called the Triangle of Biomedicine. The corners of the triangle represent research related to animals, cells and molecules, and humans; and, the position of a publication on the graph is based on its topics, as determined by its Medical Subject Headings (MeSH). We define translation as movement of a collection of articles, or the articles that cite those articles, towards the human corner. The Triangle of Biomedicine provides a quantitative way of determining if an individual scientist, research organization, funding agency, or scientific field is producing results that are relevant to clinical medicine. We validate our technique using examples that have been previously described in the literature and by comparing it to prior methods of measuring translational science. The Triangle of Biomedicine is a novel way to identify translational science and track changes over time. This is important to policy makers in evaluating the impact of the large investments being made to accelerate translation. The Triangle of Biomedicine also provides a simple visual way of depicting this impact, which can be far more powerful than numbers alone.

We define translation as movement of a collection of articles, or the articles that cite those articles, towards the human corner. Results The Triangle of Biomedicine provides a quantitative way of determining if an individual scientist, research organization, funding agency, or scientific field is producing results that are relevant to clinical medicine. We validate our technique using examples that have been previously described in the literature and by comparing it to prior methods of measuring translational science. Conclusions The Triangle of Biomedicine is a novel way to identify translational science and track changes over time. This is important to policy makers in evaluating the impact of the large investments being made to accelerate translation. The Triangle of Biomedicine also provides a simple visual way of depicting this impact, which can be

    Through the Western Water Assessment RISA program, we are conducting a research project that will produce science synthesis information to help local, state, and federal decision-makers in Colorado and Wyoming develop adaptation strategies to deal with climate-related threats to forest ecosystem services, in particular bark beetle infestations and stand-replacing wildfires. We begin by using the problem orientation framework, a policy sciences methodology, to understand how decision-makers can most effectively address policy problems that threaten the attainment of socially accepted goals. By applying this framework to the challenges facing decision-makers, we more accurately identify specific areas where scientific research can improve decision-making. WWA researchers will next begin to connect decision-makers with relevant scientific literature and identify specific areas of future scientific research that will be most effective at addressing their needs.

    Hypoxia and expression of hypoxia-related biomarkers are associated with disease progression and treatment failure in prostate cancer (PCa). We have reported that exosomes (nanovesicles of 30-150 nm in diameter) secreted by human PCa cells under hypoxia promote invasiveness and stemness in naïve PCa cells. Here, we identified the unique microRNAs (miRNAs) loaded in exosomes secreted by PCa cells under hypoxia. Using TaqMan® array microRNA cards, we analyzed the miRNA profile in exosomes secreted by human PCa LNCaP cells under hypoxic (ExoHypoxic) and normoxic (ExoNormoxic) conditions. We identified 292 miRNAs loaded in both ExoHypoxic and ExoNormoxic. The top 11 miRNAs with significantly higher level in ExoHypoxic compared to ExoNormoxic were miR-517a, miR-204, miR-885, miR-143, miR-335, miR-127, miR-542, miR-433, miR-451, miR-92a and miR-181a; and top nine miRNA with significantly lower expression level in ExoHypoxic compared to ExoNormoxic were miR-521, miR-27a, miR-324, miR-579, miR-502, miR-222, miR-135b, miR-146a and miR-491. Importantly, the two differentially expressed miRNAs miR-885 (increased expression) and miR-521 (decreased expression) showed similar expression pattern in exosomes isolated from the serum of PCa patients compared to healthy individuals. Additionally, miR-204 and miR-222 displayed correlated expression patterns in prostate tumors (Pearson R = 0.66, p < 0.0001) by The Cancer Genome Atlas (TCGA) prostate adenocarcinoma (PRAD) genomic dataset analysis. Overall, the present study identified unique miRNAs with differential expression in exosomes secreted from hypoxic PCa cells and suggests their potential usefulness as a biomarker of hypoxia in PCa patients.

    A CMC article and process for producing the article to have a layer on its surface that protects a reinforcement material within the article from damage. The method entails providing a body containing a ceramic reinforcement material in a matrix material that contains a precursor of a ceramic matrix material. A fraction of the reinforcement material is present and possibly exposed at a surface of the body. The body surface is then provided with a surface layer formed of a slurry containing a particulate material but lacking the reinforcement material of the body. The body and surface layer are heated to form the article by converting the precursor within the body to form the ceramic matrix material in which the reinforcement material is contained, and by converting the surface layer to form the protective layer that covers any fraction of the reinforcement material exposed at the body surface.

    The objectives of this study were to identify all available diabetes-related emotional distress instruments and evaluate the evidence regarding their measurement properties to help in the selection of the most appropriate instrument for use in practice and research. A systematic literature search was performed. PubMed, Embase, CINAHL, and PsycINFO were searched systematically for articles on diabetes-related emotional distress instruments. The Consensus-based Standards for the Selection of Health Measurement Instruments checklist was used to evaluate the methodological quality of the identified studies. The quality of results with respect to the measurement properties of each study was evaluated using Terwee's quality criteria. An ancillary meta-analysis was performed. Of the 2345 articles yielded by the search, 19 full-text articles evaluating 6 diabetes-related emotional distress instruments were included in this study. No instrument demonstrated evidence for all measurement properties. The Problem Areas in Diabetes scale (PAID) was the most frequently studied and the best validated of the instruments. Pooled summary estimates of the correlation coefficient between the PAID and serum glycated hemoglobin revealed a positive but weak correlation. No diabetes-related emotional distress instrument demonstrated evidence for all measurement properties. No instrument was better than another, although the PAID was the best validated and is thus recommended for use. Further psychometric studies of the diabetes-related emotional distress instruments with rigorous methodologies are required. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2015-01-01

    Background: The main aim of this study was to accumulate research evidence that introduce validated scales to measure suicidal attitudes and ideation and provide an empirical framework for adopting a relevant assessment tool in studies on suicide and suicidal behaviors. Methods: Medical Subject Headings’ (MeSH) terms were used to search Ovid Medline, PROQUEST, Wiley online library, Science Direct and PubMed for the published articles in English that reported application of an scale to measure suicidal attitudes and ideation from January 1974 onward. Results: Fourteen suicidal attitude scale and 15 scales for assessing suicidal ideation were identified in this systematic review. No gold standard approach was recognized to study suicide related attitudes and ideations. Conclusion: Special focus on generally agreed dimensions of suicidal ideation and attitudes and cross-cultural validation of the introduced scales to be applicable in different ethnic and socially diverse populations could be a promising area of research for scholars.

    With the changes introduced to medical curricula, medical students use learning resources on the Internet such as Wikipedia. However, the credibility of the medical content of Wikipedia has been questioned and there is no evidence to respond to these concerns. The aim of this paper was to critically evaluate the accuracy and reliability of the gastroenterology and hepatology information that medical students retrieve from Wikipedia. The Wikipedia website was searched for articles on gastroenterology and hepatology on 28 May 2013. Copies of these articles were evaluated by three assessors independently using an appraisal form modified from the DISCERN instrument. The articles were scored for accuracy of content, readability, frequency of updating, and quality of references. A total of 39 articles were evaluated. Although the articles appeared to be well cited and reviewed regularly, several problems were identified with regard to depth of discussion of mechanisms and pathogenesis of diseases, as well as poor elaboration on different investigations. Analysis of the content showed a score ranging from 15.6±0.6 to 43.6±3.2 (mean±SD). The total number of references in all articles was 1233, and the number of references varied from 4 to 144 (mean±SD, 31.6±27.3). The number of citations from peer-reviewed journals published in the last 5 years was 242 (28%); however, several problems were identified in the list of references and citations made. The readability of articles was in the range of -8.0±55.7 to 44.4±1.4; for all articles the readability was 26±9.0 (mean±SD). The concordance between the assessors on applying the criteria had mean κ scores in the range of 0.61 to 0.79. Wikipedia is not a reliable source of information for medical students searching for gastroenterology and hepatology articles. Several limitations, deficiencies, and scientific errors have been identified in the articles examined.

    This study identifies factors associated with self-perceived HIV-related stigma (stigma) among a cohort of individuals accessing antiretroviral therapy (ART) in British Columbia, Canada. Data were drawn from the Longitudinal Investigations into Supportive and Ancillary Health Services study, which collects social, clinical, and quality of life (QoL) information through an interviewer-administered survey. Clinical variables (i.e. CD4 count) were obtained through linkages with the British Columbia HIV/AIDS Drug Treatment Program. Multivariable linear regression was performed to determine the independent predictors of stigma. Our results indicate that among participants with high school education or greater the outcome stigma, was associated with a 3.05 stigma unit decrease (95% CI: −5.16, −0.93). Having higher relative standard of living and perceiving greater neighborhood cohesion were also associated with a decrease in stigma (−5.30 95% CI: −8.16, −2.44; −0.80 95% CI: −1.39, −0.21, respectively). Lower levels of stigma were found to be associated with better QoL measures, including perceiving better overall function (−0.90 95% CI: −1.47, −0.34), having fewer health worries (−2.11 95% CI: −2.65, −1.57), having fewer financial worries (−0.67 95% CI: −1.12, −0.23), and having less HIV disclosure concerns (−4.12 95% CI: −4.63, −3.62). The results of this study show that participants with higher education level, better QoL measures, and higher self-reported standards of living are less likely to perceive HIV-related stigma.

    Assessing the impact of individual journal articles provides information for understanding trends in science and translation of findings on practice. Citation analysis is an important way to highlight the contributions of individual author/investigator and journals on nursing practice. The purpose of this study was to identify the most frequently cited articles published in nursing journals from 1956 to 2011. The Science Citation Index Expanded and Social Sciences Citation Index were searched for citations through 2011 to articles published in the 89 nursing journals listed on the Journal Citation Reports (2010 edition). The number of citations, topic, countries, and institutions of origin based on the first author affiliation, year of publication, study design, publishing journal, journal country, and journal impact factor were noted. The most frequently cited articles published in the 89 nursing journals from 1956 to 2011 were identified. The top 50 most frequently cited articles were published in 10 nursing journals between 1970 and 2005. The top cited article received 784 citations. The most common topics were methodology for qualitative studies, validation procedures for tool development, and nursing care and practices in cancer and mental health. The most common study designs were reviews including meta-analysis and instrument validation. Most of the top 50 cited articles were published from 1986 to 1995. The findings provide insights into priorities and trends in nursing research and translational science.

    In July to August 2014, Annals of Emergency Medicine continued a collaboration with an academic Web site, Academic Life in Emergency Medicine (ALiEM), to host an online discussion session featuring the 2014 Annals Residents' Perspective article "Integration of Social Media in Emergency Medicine Residency Curriculum" by Scott et al. The objective was to describe a 14-day worldwide clinician dialogue about evidence, opinions, and early relevant innovations revolving around the featured article and made possible by the immediacy of social media technologies. Six online facilitators hosted the multimodal discussion on the ALiEM Web site, Twitter, and YouTube, which featured 3 preselected questions. Engagement was tracked through various Web analytic tools, and themes were identified by content curation. The dialogue resulted in 1,222 unique page views from 325 cities in 32 countries on the ALiEM Web site, 569,403 Twitter impressions, and 120 views of the video interview with the authors. Five major themes we identified in the discussion included curriculum design, pedagogy, and learning theory; digital curation skills of the 21st-century emergency medicine practitioner; engagement challenges; proposed solutions; and best practice examples. The immediacy of social media technologies provides clinicians the unique opportunity to engage a worldwide audience within a relatively short time frame.

    The unique canine breed structure makes dogs an excellent model for studying genetic diseases. Within a dog breed, linkage disequilibrium is extensive, enabling genome-wide association (GWA) with only around 15,000 SNPs and fewer individuals than in human studies. Incidences of specific diseases are elevated in different breeds, indicating that a few genetic risk factors might have accumulated through drift or selective breeding. In this study, a GWA study with 81 affected dogs (cases) and 57 controls from the Nova Scotia duck tolling retriever breed identified five loci associated with a canine systemic lupus erythematosus (SLE)-related disease complex that includes both antinuclear antibody (ANA)-positive immune-mediated rheumatic disease (IMRD) and steroid-responsive meningitis-arteritis (SRMA). Fine mapping with twice as many dogs validated these loci. Our results indicate that the homogeneity of strong genetic risk factors within dog breeds allows multigenic disorders to be mapped with fewer than 100 cases and 100 controls, making dogs an excellent model in which to identify pathways involved in human complex diseases.
