Background Retrospective exposure assessment of occupational lead exposure in population-based studies requires historical exposure information from many occupations and industries. Methods We reviewed published US exposure monitoring studies to identify lead exposure measurement data. We developed an occupational lead exposure database from the 175 identified papers containing 1,111 sets of lead concentration summary statistics (21% area air, 47% personal air, 32% blood). We also extracted ancillary exposure-related information, including job, industry, task/location, year collected, sampling strategy, control measures in place, and sampling and analytical methods. Results Measurements were published between 1940 and 2010 and represented 27 2-digit standardized industry classification codes. The majority of the measurements were related to lead-based paint work, joining or cutting metal using heat, primary and secondary metal manufacturing, and lead acid battery manufacturing. Conclusions This database can be used in future statistical analyses to characterize differences in lead exposure across time, jobs, and industries. PMID:25968240

Background Dietary fiber is a broad category of compounds historically defined as partially or completely indigestible plant-based carbohydrates and lignin with, more recently, the additional criteria that fibers incorporated into foods as additives should demonstrate functional human health outcomes to receive a fiber classification. Thousands of research studies have been published examining fibers and health outcomes. Objectives (1) Develop a database listing studies testing fiber and physiological health outcomes identified by experts at the Ninth Vahouny Conference; (2) Use evidence mapping methodology to summarize this body of literature. This paper summarizes the rationale, methodology, and resulting database. The database will help both scientists and policy-makers to evaluate evidence linking specific fibers with physiological health outcomes, and identify missing information. Methods To build this database, we conducted a systematic literature search for human intervention studies published in English from 1946 to May 2015. Our search strategy included a broad definition of fiber search terms, as well as search terms for nine physiological health outcomes identified at the Ninth Vahouny Fiber Symposium. Abstracts were screened using a priori defined eligibility criteria and a low threshold for inclusion to minimize the likelihood of rejecting articles of interest. Publications then were reviewed in full text, applying additional a priori defined exclusion criteria. The database was built and published on the Systematic Review Data Repository (SRDR™), a web-based, publicly available application. Conclusions A fiber database was created. This resource will reduce the unnecessary replication of effort in conducting systematic reviews by serving as both a central database archiving PICO (population, intervention, comparator, outcome) data on published studies and as a searchable tool through which this data can be extracted and updated.

To understand the current situation and developmental trend of anthelmintics in English journals through a bibliometric analysis. The literature was searched in Pubmed Database (1997-2007) using the following key words: "drug therapy", "anthelmintics", "humans", "pharmacology", and "parasitology". Access Database was constructed by relative literature through proper data admission method. The relative articles in the database were sorted by different categories, such as "research categories", "publishing year" and "research drug". Data were analyzed by using SPSS software. The annual number of anthelmintics articles increased steadily from year 1997 to 2007. The average number of annual increase was about 6. The major research category was applied research. The major diseases were schistosomiasis, filariasis, ascariasis, echinococcosis and hookworm disease. The number of articles on schistosomiasis was higher than that of other four diseases (P<0.05). The major drugs involved were albendazole, praziquantel, mebendazole, ivermectin and diethylcarbamazine. Articles on the anthelmintics were published mostly in medical journals. From the total database, articles published at the top five journals occupied 5.52%, 4.39%, 3.76%, 3.26%, and 3.26%, respectively. Increasingly importance has been attached to anthelmintics in the last decade. Meanwhile, the researchers focused on a few anthelmintics, and it is inevitable to develop new drugs.

To identify and qualitatively describe, in a literature review, how the instruments were used to evaluate patient safety culture in the operating rooms of published studies. Systematic searches of the literature were conducted using the major database including MEDLINE, EMbase, The Cochrane Library, and four Chinese databases including Chinese Biomedical Literature Database (CBM), Wanfang Data, Chinese Scientific Journal Database (VIP), and Chinese Journals Full-text Database (CNKI) for studies published up to March 2016. We summarized and analyzed the country scope, the instrument utilized in the study, the year when the instrument was used, and fields of operating rooms. Study populations, study settings, and the time span between baseline and follow-up phase were evaluated according to the study design. We identified 1025 references, of which 99 were obtained for full-text assessment; 47 of these studies were deemed relevant and included in the literature review. Most of the studies were from the USA. The most commonly used patient safety culture instrument was Safety Attitude Questionnaire. All identified instruments were used after 2002 and across many fields. Most included studies on patient safety culture were conducted in teaching hospitals or university hospitals. The study population in the cross-sectional studies was much more than that in the before-after studies. The time span between baseline and follow-up phase of before-after studies were almost over three months. Although patient safety culture is considered important in health care and patient safety, the number of studies in which patient safety culture has been estimated using the instruments in operating rooms, is fairly small. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

Alkhateeb, Jamal M; Hadidi, Muna S; Alkhateeb, Amal J

2016-01-01

In this study, a literature review was conducted to analyze studies published from 1990 to 2014 in English-written literature on inclusion of children with developmental disabilities in Arab countries. This study sought to review and analyze research conducted on Inclusive Education (IE) in Arab countries. The following electronic databases were used in searching the relevant literature: ScienceDirect, SpringerLink, PsychINFO, EBSCOhost Databases, ProQuest Dissertations and Theses Database, ERIC, and Google Scholar. After the publications to be included in this study were retrieved, each study was reviewed and analyzed. Each study was examined for details such as authors, title of research, publication year, country, purpose, methods, and key findings. The results showed that a total of 42 empirical studies related to inclusion of children with developmental disabilities in Arab countries have been published. More than two-thirds of these studies came from United Arab Emirates (UAE), Jordan, and Saudi Arabia. The majority of the studies were published in the last 6 years. The main parameters in these studies were: attitudes toward inclusion, barriers to inclusion, and evaluating inclusion. The results of the current study revealed that relatively little IE research has been conducted in Arab countries. More research is warranted to test the generalizability of the results of the current study. Further research is also needed to analyze IE practices and demonstrate strategies for the effective implementation of IE in these countries. Copyright © 2015 Elsevier Ltd. All rights reserved.

Programmatic and teaching initiatives for ethnically diverse nursing students: a literature review.

PubMed

Torregosa, Marivic B; Morin, Karen H

2012-06-01

The purpose of this study was to examine the evidence of programmatic and teaching initiatives implemented by nursing faculty to enhance the academic success rates of ethnically diverse students (EDS). A search of the literature in the Cumulative Index to Nursing and Allied Health Literature and MEDLINE databases, wherein primary sources about programmatic and teaching initiative to promote academic success among EDS, was conducted. Using specific the Cumulative Index to Nursing and Allied Health Literature subject headings and Medical Subject Headings, 230 articles were retrieved from both databases. A total of 22 peer-reviewed articles published between 2000 and 2011 were included in the literature review. We found that evidence on the predominant programmatic and teaching initiatives for EDS academic success was inconclusive. The most common programmatic and teaching initiatives implemented by nursing faculty were peer mentoring, faculty-student mentoring, social networking, academic support, and financial support. Although positive student outcomes were reported about programmatic and teaching initiatives for EDS, the evidence remained inconclusive. Recommendations for policy and future research in this area of nursing education research were provided. Copyright © 2012. Published by Elsevier B.V.

This paper is the third chronological supplement to the Carcinogenic Potency Database that first appeared in this journal in 1984. We report here results of carcinogenesis bioassays published in the general literature between January 1985 and December 1986, and in Technical Reports of the National Toxicology Program between June 1986 and June 1987. This supplement includes results of 337 long-term, chronic experiments of 121 compounds, and reports the same information about each experiment in the same plot format as the earlier papers, e.g., the species and strain of animal, the route and duration of compound administration, dose level, and other aspects of experimental protocol, histopathology, and tumor incidence, TD50 (carcinogenic potency) and its statistical significance, dose response, opinion of the author about carcinogenicity, and literature citation. The reader needs to refer to the 1984 publication for a guide to the plot of the database, a complete description of the numerical index of carcinogenic potency, and a discussion of the sources of data, the rationale for the inclusion of particular experiments and particular target sites, and the conventions adopted in summarizing the literature. The four plots of the database are to be used together as results published earlier are not repeated. In all, the four plots include results for approximately 4000 experiments on 1050 chemicals. Appendix 14 of this paper is an alphabetical index to all chemicals in the database and indicates which plot(s) each chemical appears in. A combined plot of all results from the four separate papers, that is ordered alphabetically by chemical, is available from the first author, in printed form or on computer tape or diskette.

Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

We present a bibliometric analysis of recently published full economic evaluations of health interventions and reflect critically on the implications of our findings for this growing field. We created a database drawing on 14 health, economic, and/or general literature databases for articles published between 1 January 2012 and 3 May 2014 and identified 2844 economic evaluations meeting our criteria. We present findings regarding the sensitivity, specificity, and added value of searches in the different databases. We examine the distribution of publications between countries, regions, and health areas studied and compare the relative volume of research with disease burden. We analyse authors' country and institutional affiliations, journals and journal type, language, and type of economic evaluation conducted. More than 1200 economic evaluations were published annually, of which 4% addressed low-income countries, 4% lower-middle-income countries, 14% upper-middle-income countries, and 83% high-income countries. Across country income levels, 53, 54, 86, and 100% of articles, respectively, included an author based in a country within the income level studied. Biomedical journals published 74% of economic evaluations. The volume of research across health areas correlates more closely with disease burden in high-income than in low-income and middle-income countries. Our findings provide an empirical basis for further study on methods, research prioritization, and capacity development in health economic evaluation. © 2016 The Authors.

2012-01-01

Vision Science is considered to be a quite developed discipline in Nepal, with much research currently in progress. Though the results of these endeavors are published in scientific journals, formal citation analyses have not been performed on works contributed by Nepalese vision scientists. To study Nepal's contribution to vision science literature in the database "Web of Science". The primary data source of this paper was Web of Science, a citation database of Thomas Reuters. All bibliometric analyses were performed with the help of Web of Science analysis service. In the current database of vision science literature, Nepalese authors contributed 112 publications to Web of Science, 95 of which were original articles. Pokharel GP had the highest number of citations among contributing authors of Nepal. Hennig A contributed the highest number of article as a first author. The Nepal Eye Hospital contributed the highest number of articles as an institution to the field of Vision Science. Currently, only two journals from Nepal including Journal of Nepal Medical Association (JAMA) are indexed in the Web of Science database (Sieving, 2012). To evaluate the total productivity of vision science literature from Nepal, total publication counts from national journals and articles indexed in other databases such as PubMed and Scopus must also be considered. © NEPjOPH.

Ebola virus disease (hereafter EVD or Ebola) has a high fatality rate. The devastating effects of the current epidemic of Ebola in West Africa have put the global health response in acute focus. In response, the World Health Organization (WHO) has declared the Ebola outbreak in West Africa as a "Public Health Emergency of International Concern". A small proportion of scientific literature is dedicated to Ebola research. To identify global research trends in Ebola research, the Institute for Scientific Information (ISI) Web of Science™ database was used to search for data, which encompassed original articles published from 1900 to 2013. The keyword "Ebola" was used to identify articles for the purposes of this review. In order to include all published items, the database was searched using the Basic Search method. The earliest record of literature about Ebola indexed in the Web of Science is from 1977. A total of 2477 publications on Ebola, published between 1977 and 2014 (with the number of publications increasing annually), were retrieved from the database. Original research articles (n = 1623, 65.5%) were the most common type of publication. Almost all (96.5%) of the literature in this field was in English. The USA had the highest scientific output and greatest number of funding agencies. Journal of Virology published 239 papers on Ebola, followed by Journal of Infectious Diseases and Virology, which published 113 and 99 papers, respectively. A total of 1911 papers on Ebola were cited 61,477 times. This analysis identified the current state of research and trends in studies about Ebola between 1977 and 2014. Our bibliometric analysis provides a historical perspective on the progress in Ebola research.

Databases are systematic tools to archive and manage information related to marine mammal stranding and mortality events. Stranding response networks, governmental authorities and non-governmental organizations have established regional or national stranding networks and have developed unique standard stranding response and necropsy protocols to document and track stranded marine mammal demographics, signalment and health data. The objectives of this study were to (1) describe and review the current status of marine mammal stranding and mortality databases worldwide, including the year established, types of database and their goals; and (2) summarize the geographic range included in the database, the number of cases recorded, accessibility, filter and display methods. Peer-reviewed literature was searched, focussing on published databases of live and dead marine mammal strandings and mortality and information released from stranding response organizations (i.e. online updates, journal articles and annual stranding reports). Databases that were not published in the primary literature or recognized by government agencies were excluded. Based on these criteria, 10 marine mammal stranding and mortality databases were identified, and strandings and necropsy data found in these databases were evaluated. We discuss the results, limitations and future prospects of database development. Future prospects include the development and application of virtopsy, a new necropsy investigation tool. A centralized web-accessed database of all available postmortem multimedia from stranded marine mammals may eventually support marine conservation and policy decisions, which will allow the use of marine animals as sentinels of ecosystem health, working towards a 'One Ocean-One Health' ideal.

The Saccharomyces Genome Database (SGD; http://www.yeastgenome.org) is an expertly curated database of literature-derived functional information for the model organism budding yeast, Saccharomyces cerevisiae. SGD constantly strives to synergize new types of experimental data and bioinformatics predictions with existing data, and to organize them into a comprehensive and up-to-date information resource. The primary mission of SGD is to facilitate research into the biology of yeast and to provide this wealth of information to advance, in many ways, research on other organisms, even those as evolutionarily distant as humans. To build such a bridge between biological kingdoms, SGD is curating data regarding yeast-human complementation, in which a human gene can successfully replace the function of a yeast gene, and/or vice versa. These data are manually curated from published literature, made available for download, and incorporated into a variety of analysis tools provided by SGD. © The Author(s) 2017.

Chinese journals in epidemiology, preventive medicine and public health contain much that is of potential international interest. However, few non-Chinese speakers are acquainted with this literature. This article therefore provides an overview of the contemporary scene in Chinese biomedical journal publication, Chinese bibliographic databases and Chinese journals in epidemiology, preventive medicine and public health. The challenge of switching to English as the medium of publication, the development of publishing bibliometric data from Chinese databases, the prospect of an Open Access publication model in China, the issue of language bias in literature reviews and the quality of Chinese journals are discussed. Epidemiologists are encouraged to search the Chinese bibliographic databases for Chinese journal articles. PMID:18826604

Optimizing literature search in systematic reviews - are MEDLINE, EMBASE and CENTRAL enough for identifying effect studies within the area of musculoskeletal disorders?

PubMed

Aagaard, Thomas; Lund, Hans; Juhl, Carsten

2016-11-22

When conducting systematic reviews, it is essential to perform a comprehensive literature search to identify all published studies relevant to the specific research question. The Cochrane Collaborations Methodological Expectations of Cochrane Intervention Reviews (MECIR) guidelines state that searching MEDLINE, EMBASE and CENTRAL should be considered mandatory. The aim of this study was to evaluate the MECIR recommendations to use MEDLINE, EMBASE and CENTRAL combined, and examine the yield of using these to find randomized controlled trials (RCTs) within the area of musculoskeletal disorders. Data sources were systematic reviews published by the Cochrane Musculoskeletal Review Group, including at least five RCTs, reporting a search history, searching MEDLINE, EMBASE, CENTRAL, and adding reference- and hand-searching. Additional databases were deemed eligible if they indexed RCTs, were in English and used in more than three of the systematic reviews. Relative recall was calculated as the number of studies identified by the literature search divided by the number of eligible studies i.e. included studies in the individual systematic reviews. Finally, cumulative median recall was calculated for MEDLINE, EMBASE and CENTRAL combined followed by the databases yielding additional studies. Deemed eligible was twenty-three systematic reviews and the databases included other than MEDLINE, EMBASE and CENTRAL was AMED, CINAHL, HealthSTAR, MANTIS, OT-Seeker, PEDro, PsychINFO, SCOPUS, SportDISCUS and Web of Science. Cumulative median recall for combined searching in MEDLINE, EMBASE and CENTRAL was 88.9% and increased to 90.9% when adding 10 additional databases. Searching MEDLINE, EMBASE and CENTRAL was not sufficient for identifying all effect studies on musculoskeletal disorders, but additional ten databases did only increase the median recall by 2%. It is possible that searching databases is not sufficient to identify all relevant references, and that reviewers must rely upon additional sources in their literature search. However further research is needed.

2016-06-01

The purpose of this study was to explore the literature on chronic pain in adults with Marfan syndrome (MFS), critically appraising and synthesizing relevant literature. A systematic review was conducted by searching the published literature databases using available medical, physical, psychological, social databases and other sources. All studies that addressed pain in MFS, published in peer-reviewed journals were assessed. Of 351 search results, 18 articles satisfied the eligibility criteria. All studies were cross-sectional and quantitative; no randomized controlled trials or intervention studies were found. Most studies had small sample sizes, low response rates and mainly dealt with other aspects of the diagnosis than pain. Only one article dealt mainly with pain. The research on chronic pain in MFS is limited in size and quality. Despite these limitations, studies describe that the prevalence of pain in patients with MFS is high, varying from 47 to 92% and affecting several anatomic sites. In addition, chronic pain limits daily function and few studies describe treatment options for pain in patients with MFS. Research is needed to obtain more evidence-based knowledge for developing more appropriate rehabilitation programs for people with MFS. © 2015 John Wiley & Sons A/S.

This paper presents two types of information from the Carcinogenic Potency Database (CPDB): (a) the sixth chronological plot of analyses of long-term carcinogenesis bioassays, and (b) an index to chemicals in all six plots, including a summary compendium of positivity and potency for each chemical (Appendix 14). The five earlier plots of the CPDB have appeared in this journal, beginning in 1984 (1-5). Including the plot in this paper, the CPDB reports results of 5002 experiments on 1230 chemicals. This paper includes bioassay results published in the general literature between January 1989 and December 1990, and in Technical Reports of the National Toxicology Program between January 1990 and June 1993. Analyses are included on 17 chemicals tested in nonhuman primates by the Laboratory of Chemical Pharmacology, National Cancer Institute. This plot presents results of 531 long-term, chronic experiments of 182 test compounds and includes the same information about each experiment in the same plot format as the earlier papers: the species and strain of test animal, the route and duration of compound administration, dose level and other aspects of experimental protocol, histopathology and tumor incidence, TD50 (carcinogenic potency) and its statistical significance, dose response, author's opinion about carcinogenicity, and literature citation. We refer the reader to the 1984 publications (1,6,7) for a detailed guide to the plot of the database, a complete description of the numerical index of carcinogenic potency, and a discussion of the sources of data, the rationale for the inclusion of particular experiments and particular target sites, and the conventions adopted in summarizing the literature. The six plots of the CPDB are to be used together since results of individual experiments that were published earlier are not repeated. Appendix 14 is designed to facilitate access to results on all chemicals. References to the published papers that are the source of experimental data are reported in each of the published plots. For readers using the CPDB extensively, a combined plot is available of all results from the six separate plot papers, ordered alphabetically by chemical; the combined plot in printed form or on computer tape or diskette is available from the first author. A SAS database is also available. PMID:8741772

The authors examined representations of African Americans in the grief literature to assess (a) frequencies; (b) content; and (c) use of universalist or a contextualized framework. They conducted searches in 3 databases that target the grief literature published in the last 15 years. Fifty-nine articles met the criteria. There are a small number of studies published on African Americans and these tend to focus on homicide. Many studies had incomplete methods. Comparison studies were common and pathological grief outcomes that were validated on White populations were used as outcome variables with African American participants.

The Staff of the Waste Management Document Library (WMDL), in cooperation with Allen Croff have been requested to provide information support for a historical search concerning waste categorization/classification. This bibliography has been compiled under the sponsorship of Oak Ridge National Laboratory`s Chemical Technology Division to help in Allen`s ongoing committee work with the NRC/NRCP. After examining the search, Allen Croff saw the value of the search being published. Permission was sought from the database providers to allow limited publication (i.e. 20--50 copies) of the search for internal distribution at the Oak Ridge National Laboratory and for Allen Croff`s associated committee.more » Citations from the database providers who did not grant legal permission for their material to be published have been omitted from the literature review. Some of the longer citations have been included in an abbreviated form in the search to allow the format of the published document to be shortened from approximately 1,400 pages. The bibliography contains 372 citations.« less

Administrative claims databases provide a wealth of data for assessing the effect of treatments in clinical practice. Our aim was to propose methodology for real-world studies in multiple sclerosis (MS) using these databases. In three large US administrative claims databases: MarketScan, PharMetrics Plus and Department of Defense (DoD), patients with MS were selected using an algorithm identified in the published literature and refined for accuracy. Algorithms for detecting newly diagnosed ('incident') MS cases were also refined and tested. Methodology based on resource and treatment use was developed to differentiate between relapses with and without hospitalization. When various patient selection criteria were applied to the MarketScan database, an algorithm requiring two MS diagnoses at least 30 days apart was identified as the preferred method of selecting patient cohorts. Attempts to detect incident MS cases were confounded by the limited continuous enrollment of patients in these databases. Relapse detection algorithms identified similar proportions of patients in the MarketScan and PharMetrics Plus databases experiencing relapses with (2% in both databases) and without (15-20%) hospitalization in the 1 year follow-up period, providing findings in the range of those in the published literature. Additional validation of the algorithms proposed here would increase their credibility. The methods suggested in this study offer a good foundation for performing real-world research in MS using administrative claims databases, potentially allowing evidence from different studies to be compared and combined more systematically than in current research practice.

Clinical prediction models (CPMs) estimate the probability of clinical outcomes and hold the potential to improve decision making and individualize care. For patients with cardiovascular disease, there are numerous CPMs available although the extent of this literature is not well described. We conducted a systematic review for articles containing CPMs for cardiovascular disease published between January 1990 and May 2012. Cardiovascular disease includes coronary heart disease, heart failure, arrhythmias, stroke, venous thromboembolism, and peripheral vascular disease. We created a novel database and characterized CPMs based on the stage of development, population under study, performance, covariates, and predicted outcomes. There are 796 models included in this database. The number of CPMs published each year is increasing steadily over time. Seven hundred seventeen (90%) are de novo CPMs, 21 (3%) are CPM recalibrations, and 58 (7%) are CPM adaptations. This database contains CPMs for 31 index conditions, including 215 CPMs for patients with coronary artery disease, 168 CPMs for population samples, and 79 models for patients with heart failure. There are 77 distinct index/outcome pairings. Of the de novo models in this database, 450 (63%) report a c-statistic and 259 (36%) report some information on calibration. There is an abundance of CPMs available for a wide assortment of cardiovascular disease conditions, with substantial redundancy in the literature. The comparative performance of these models, the consistency of effects and risk estimates across models and the actual and potential clinical impact of this body of literature is poorly understood. © 2015 American Heart Association, Inc.

BINABITROP is a bibliographical database of more than 38000 records about the ecosystems and organisms of Costa Rica. In contrast with commercial databases, such as Web of Knowledge and Scopus, which exclude most of the scientific journals published in tropical countries, BINABITROP is a comprehensive record of knowledge on the tropical ecosystems and organisms of Costa Rica. We analyzed its contents in three sites (La Selva, Palo Verde and Las Cruces) and recorded scientific field, taxonomic group and authorship. We found that most records dealt with ecology and systematics, and that most authors published only one article in the study period (1963-2011). Most research was published in four journals: Biotropica, Revista de Biología Tropical/ International Journal of Tropical Biology and Conservation, Zootaxa and Brenesia. This may be the first study of a such a comprehensive database for any case of tropical biology literature.

Yaylali, Ibrahim Ethem; Alaçam, Tayfun

2016-06-01

The aim of this study was to perform an overview of literature search strategies in systematic reviews (SRs) published in 2 endodontic journals, Journal of Endodontics and International Endodontic Journal. A search was done by using the MEDLINE (PubMed interface) database to retrieve the articles published between January 1, 2000 and December 31, 2015. The last search was on January 10, 2016. All the SRs published in the 2 journals were retrieved and screened. Eligible SRs were assessed by using 11 questions about search strategies in the SRs that were adapted from 2 guidelines (ie, AMSTAR checklist and the Cochrane Handbook). A total of 83 SRs were retrieved by electronic search. Of these, 55 were from the Journal of Endodontics, and 28 were from the International Endodontic Journal. After screening, 2 SRs were excluded, and 81 SRs were included in the study. Some issues, such as search of grey literature and contact with study authors, were not fully reported (30% and 25%, respectively). On the other hand, some issues, such as the use of index terms and key words and search in at least 2 databases, were reported in most of the SRs (97% and 95%, respectively). The overall quality of the search strategy in both journals was 61%. No significant difference was found between the 2 journals in terms of evaluation criteria (P > .05). There exist areas for improving the quality of reporting of search strategies in SRs; for example, grey literature should be searched for unpublished studies, no language limitation should be applied to databases, and authors should make an attempt to contact the authors of included studies to obtain further relevant information.

2015-12-01

The ESO Telescope Bibliography (telbib) is a database of refereed papers published by the ESO users community. It links data in the ESO Science Archive with the published literature, and vice versa. Developed and maintained by the ESO library, telbib also provides insights into the organization's research output and impact as measured through bibliometric studies. Curating telbib is a multi-step process that involves extensive tagging of the database records. Based on selected use cases, this talk will explain how the rich metadata provide parameters for reports and statistics in order to investigate the performance of ESO's facilities and to understand trends and developments in the publishing behaviour of the user community.

MimoSA: a system for minimotif annotation

PubMed Central

2010-01-01

Background Minimotifs are short peptide sequences within one protein, which are recognized by other proteins or molecules. While there are now several minimotif databases, they are incomplete. There are reports of many minimotifs in the primary literature, which have yet to be annotated, while entirely novel minimotifs continue to be published on a weekly basis. Our recently proposed function and sequence syntax for minimotifs enables us to build a general tool that will facilitate structured annotation and management of minimotif data from the biomedical literature. Results We have built the MimoSA application for minimotif annotation. The application supports management of the Minimotif Miner database, literature tracking, and annotation of new minimotifs. MimoSA enables the visualization, organization, selection and editing functions of minimotifs and their attributes in the MnM database. For the literature components, Mimosa provides paper status tracking and scoring of papers for annotation through a freely available machine learning approach, which is based on word correlation. The paper scoring algorithm is also available as a separate program, TextMine. Form-driven annotation of minimotif attributes enables entry of new minimotifs into the MnM database. Several supporting features increase the efficiency of annotation. The layered architecture of MimoSA allows for extensibility by separating the functions of paper scoring, minimotif visualization, and database management. MimoSA is readily adaptable to other annotation efforts that manually curate literature into a MySQL database. Conclusions MimoSA is an extensible application that facilitates minimotif annotation and integrates with the Minimotif Miner database. We have built MimoSA as an application that integrates dynamic abstract scoring with a high performance relational model of minimotif syntax. MimoSA's TextMine, an efficient paper-scoring algorithm, can be used to dynamically rank papers with respect to context. PMID:20565705

Corvids (Corvidae) play a major role in ornithological research. Because of their worldwide distribution, diversity and adaptiveness, they have been studied extensively. The aim of the Corvids Literature Database (CLD, http://www.corvids.de/cld) is to record all publications (citation format) on all extant and extinct Crows, Ravens, Jays and Magpies worldwide and tag them with specific keywords making them available for researchers worldwide. The self-maintained project started in 2006 and today comprises 8000 articles, spanning almost 500 years. The CLD covers publications from 164 countries, written in 36 languages and published by 8026 authors in 1503 journals (plus books, theses and other publications). Forty-nine percent of all records are available online as full-text documents or deposited in the physical CLD archive. The CLD contains 442 original corvid descriptions. Here, we present a metadata assessment of articles recorded in the CLD including a gap analysis and prospects for future research. Database URL: http://www.corvids.de/cld. © The Author(s) 2016.

Perhaps more than any other science discipline-based education research field, the scholarly literature base describing and documenting astronomy education research is highly fragmented and widely dispersed across numerous journals. The resulting wide diversity of journals that publish astronomy education research presents an arduous challenge for scholars trying to best understand what work has been done and what work still needs to be done. Moreover, a vast amount of education research on the teaching and learning of astronomy exists in dissertations that were never published and even more exists in the realm of un-disseminated grey literature hosted in conference proceedings and society newsletters going back decades. With a few notable exceptions far less extensive than the current project, there has been no comprehensive repository for cataloging astronomy education research methods and results to date. In response, an international cadre of scholars coordinated by the CAPER Center for Astronomy & Physics Education Research are creating the underlying structure for an online database in order to conduct an international Study of Astronomy Reasoning, iSTAR, project. The online iSTAR database serves as an online host to bring together in one place digital copies of hard to locate journal articles, isolated dissertations and theses, and professional meeting contributions to extend the world's scholars abilities to more easily find and utilize a far broader collection of astronomy education research literature than has been previously available. Works are categorized by research method, nature of study-participants, educational learning venue studied, country and language of the study, and other fruitfully useful categories. Scholars wishing to add their own literature resources are encouraged to contribute to the online database located at istardatabase.org

To conduct a systematic review of the literature to identify existing online primary care quality improvement tools and resources to support organisational improvement related to the seven elements in the Primary Care Practice Improvement Tool (PC-PIT), with the identified tools and resources to progress to a Delphi study for further assessment of relevance and utility. Systematic review of the international published and grey literature. CINAHL, Embase and PubMed databases were searched in March 2014 for articles published between January 2004 and December 2013. GreyNet International and other relevant websites and repositories were also searched in March-April 2014 for documents dated between 1992 and 2012. All citations were imported into a bibliographic database. Published and unpublished tools and resources were included in the review if they were in English, related to primary care quality improvement and addressed any of the seven PC-PIT elements of a high-performing practice. Tools and resources that met the eligibility criteria were then evaluated for their accessibility, relevance, utility and comprehensiveness using a four-criteria appraisal framework. We used a data extraction template to systematically extract information from eligible tools and resources. A content analysis approach was used to explore the tools and resources and collate relevant information: name of the tool or resource, year and country of development, author, name of the organisation that provided access and its URL, accessibility information or problems, overview of each tool or resource and the quality improvement element(s) it addresses. If available, a copy of the tool or resource was downloaded into the bibliographic database, along with supporting evidence (published or unpublished) on its use in primary care. This systematic review identified 53 tools and resources that can potentially be provided as part of a suite of tools and resources to support primary care practices in improving the quality of their practice, to achieve improved health outcomes.

Astronomy Education Research Observations from the iSTAR international Study of Astronomical Reasoning Database

Historically, an important part of the scientific research cycle is to situate any research project within the landscape of the existing scientific literature. In the field of discipline-based astronomy education research, grappling with the existing literature base has proven difficult because of the difficulty in obtaining research reports from around the world, particularly early ones. In order to better survey and efficiently utilize the wide and fractured range and domain of astronomy education research methods and results, the iSTAR international Study of Astronomical Reasoning database project was initiated. The project aims to host a living, online repository of dissertations, theses, journal articles, and grey literature resources to serve the world's discipline-based astronomy education research community. The first domain of research artifacts ingested into the iSTAR database were doctoral dissertations. To the authors' great surprise, nearly 300 astronomy education research dissertations were found from the last 100-years. Few, if any, of the literature reviews from recent astronomy education dissertations surveyed even come close to summarizing this many dissertations, most of which have not been published in traditional journals, as re-publishing one's dissertation research as a journal article was not a widespread custom in the education research community until recently. A survey of the iSTAR database dissertations reveals that the vast majority of work has been largely quantitative in nature until the last decade. We also observe that modern-era astronomy education research writings reaches as far back as 1923 and that the majority of dissertations come from the same eight institutions. Moreover, most of the astronomy education research work has been done covering learners' grasp of broad knowledge of astronomy rather than delving into specific learning targets, which has been more in vogue during the last two decades. The surprisingly wide breadth of largely unknown research revealed in the iSTAR database motivates us to begin to synthesize the research and look for broader themes using widely accepted meta analysis techniques.

The aim of this study is to present a review based on the literature and proceedings from selected telemedicine conferences. The review was developed using the PRISMA framework. The Embase and PubMed (updated until July 13, 2015) literature databases were searched for telemedicine-related terms and Poland. The literature search identified 129 eligible articles in the databases and 85 in conference proceedings until July 2015. Articles measured as a number of contributions per year presented a similar rising, fluctuating and almost parallel pattern. Fifty-nine percent of the reviewed papers were published in impacted journals. Almost half of all publications presented original papers. The published articles concerned mostly cardiology (16%), family medicine (15%) and pathology (11%). Conference proceedings papers concerned orthopedics (29%, significantly more frequent; p < 0.001) and cardiology (14%). Scientific activity of researchers and practitioners in Poland in the field of telemedicine is not high, but it is increasing over time. There is a tendency to present the research rather in high-quality journals instead of conferences before publication. The occurrence of individual medical specialty telemedicine in Poland may reflect country-specific needs.

Bias in benefit-risk appraisal in older products: the case of buflomedil for intermittent claudication.

PubMed

De Backer, Tine L M; Vander Stichele, Robert H; Van Bortel, Luc M

2009-01-01

Benefit-risk assessment should be ongoing during the life cycle of a pharmaceutical agent. New products are subjected to rigorous registration laws and rules, which attempt to assure the availability and validity of evidence. For older products, bias in benefit-risk assessment is more likely, as a number of safeguards were not in place at the time these products were registered. This issue of bias in benefit-risk assessment of older products is illustrated here with an example: buflomedil in intermittent claudication. Data on efficacy were retrieved from a Cochrane systematic review. Data on safety were obtained by comparing the number of reports of serious adverse events and fatalities published in the literature with those reported in postmarketing surveillance databases. In the case of efficacy, the slim basis of evidence for the benefit of buflomedil is undermined by documented publication bias. In the case of safety, bias in reporting to international safety databases is illustrated by the discrepancy between the number of drug-related deaths published in the literature (20), the potentially drug-related deaths in the WHO database (20) and deaths attributed to buflomedil in the database of the international marketing authorization holder (11). In older products, efficacy cannot be evaluated without a thorough search for publication bias. For safety, case reporting of drug-related serious events and deaths in the literature remains a necessary instrument for risk appraisal of older medicines, despite the existence of postmarketing safety databases. The enforcement of efficient communication between healthcare workers, drug companies, national centres of pharmacovigilance, national poison centers and the WHO is necessary to ensure the validity of postmarketing surveillance reporting systems. Drugs considered obsolete because of unfavourable benefit-risk assessment should not be allowed to stay on the market.

2018-04-18

To create a protocol that could be used to construct chemical information database from scientific literature quickly and automatically. Scientific literature, patents and technical reports from different chemical disciplines were collected and stored in PDF format as fundamental datasets. Chemical structures were transformed from published documents and images to machine-readable data by using the name conversion technology and optical structure recognition tool CLiDE. In the process of molecular structure information extraction, Markush structures were enumerated into well-defined monomer molecules by means of QueryTools in molecule editor ChemDraw. Document management software EndNote X8 was applied to acquire bibliographical references involving title, author, journal and year of publication. Text mining toolkit ChemDataExtractor was adopted to retrieve information that could be used to populate structured chemical database from figures, tables, and textual paragraphs. After this step, detailed manual revision and annotation were conducted in order to ensure the accuracy and completeness of the data. In addition to the literature data, computing simulation platform Pipeline Pilot 7.5 was utilized to calculate the physical and chemical properties and predict molecular attributes. Furthermore, open database ChEMBL was linked to fetch known bioactivities, such as indications and targets. After information extraction and data expansion, five separate metadata files were generated, including molecular structure data file, molecular information, bibliographical references, predictable attributes and known bioactivities. Canonical simplified molecular input line entry specification as primary key, metadata files were associated through common key nodes including molecular number and PDF number to construct an integrated chemical information database. A reasonable construction protocol of chemical information database was created successfully. A total of 174 research articles and 25 reviews published in Marine Drugs from January 2015 to June 2016 collected as essential data source, and an elementary marine natural product database named PKU-MNPD was built in accordance with this protocol, which contained 3 262 molecules and 19 821 records. This data aggregation protocol is of great help for the chemical information database construction in accuracy, comprehensiveness and efficiency based on original documents. The structured chemical information database can facilitate the access to medical intelligence and accelerate the transformation of scientific research achievements.

Hernia is a common problem of the modern world with its incidence more in developing countries. Inguinal hernia is the most common groin hernia repaired worldwide. With advancement in technology operative techniques of repair have also evolved. A PubMed and COCHRANE database search was accomplished in this regard to establish the current status of laparoscopic inguinal hernia repair in view of recent published literature. Published literature support that laparoscopic hernia repair is best suited for recurrent and bilateral inguinal hernia although it may be offered for primary inguinal hernia if expertise is available.

Every day there are 10,000 scientific articles published. Since the Consultation-Liaison ("C-L") psychiatrist may be asked to consult on a patient with any medical illness, e.g., severe acute respiratory syndrome (SARS), malaria, cancer, stroke, amytrophic, lateral sclerosis, and a patient who may be on any medical drug, methods need to be developed to review the recent literature and have an awareness of key and essential current findings. At the same time, teachers need to develop a current listing of seminal papers for trainees and practitioners of this newest cross-over subspecialty of psychiatry-now called Psychosomatic Medicine. Experts selected because of their writings and acknowledged contributions to a specific clinical area or problem hope examined thousands of citations to choose those articles, chapters, books, or letters that they regard as most important to Psychosomatic Medicine. In addition, psychiatric specialists in six countries have provided their national Psychosomatic Medicine (Consultation-Liaison) lists as examples of what they regard as the most important teaching materials journals: Australia, Brazil, Greece, Mexico, Portugal, and Taiwan. It is our belief that a cogent, international, systematic review will provide the greatest success in creating a "regionally appropriate" teaching and consultation literature database with world-wide applicability. We review our current progress on this literature database and software, the technical system and data organization involved, the approach used to populate the literature system, and ongoing development plans to bring this system to the physician via mobile technologies.

PubMed is generally acknowledged for its scientificity in literature coverage and authority of literature retrieval . In recent years, many studies have been published in China about radiation oncology. We aimed to investigate the literatures about radiation oncology in China covered by PubMed over the past five years. We collected primary data by searching the PubMed database using the related subject words. The collected data were analyzed and evaluated by bibliometric methods. In the past five years, 550 articles by Chinese authors related to radiotherapy were indexed in PubMed. These articles were published in 160 journals among 26 Chinese provinces/cities. These articles mainly focused on radiation dose and computer-aided radiation therapy. Sixty-four articles were published by Chinese Journal of Cancer , which ranked the top. Forty-four articles were published by the International Journal of Radiation Oncology Biology Physics (IF=4.29), with the largest number among SCI journals. One hundred and sixteen articles from Guangdong Province were covered, accounting for 21.09%. Over the past five years, the discipline of radiation oncology has been greatly developed. The literatures mainly focus on clinical radiation oncology and their regional distribution is uneven.

Automatic categorization of diverse experimental information in the bioscience literature

PubMed Central

2012-01-01

Background Curation of information from bioscience literature into biological knowledge databases is a crucial way of capturing experimental information in a computable form. During the biocuration process, a critical first step is to identify from all published literature the papers that contain results for a specific data type the curator is interested in annotating. This step normally requires curators to manually examine many papers to ascertain which few contain information of interest and thus, is usually time consuming. We developed an automatic method for identifying papers containing these curation data types among a large pool of published scientific papers based on the machine learning method Support Vector Machine (SVM). This classification system is completely automatic and can be readily applied to diverse experimental data types. It has been in use in production for automatic categorization of 10 different experimental datatypes in the biocuration process at WormBase for the past two years and it is in the process of being adopted in the biocuration process at FlyBase and the Saccharomyces Genome Database (SGD). We anticipate that this method can be readily adopted by various databases in the biocuration community and thereby greatly reducing time spent on an otherwise laborious and demanding task. We also developed a simple, readily automated procedure to utilize training papers of similar data types from different bodies of literature such as C. elegans and D. melanogaster to identify papers with any of these data types for a single database. This approach has great significance because for some data types, especially those of low occurrence, a single corpus often does not have enough training papers to achieve satisfactory performance. Results We successfully tested the method on ten data types from WormBase, fifteen data types from FlyBase and three data types from Mouse Genomics Informatics (MGI). It is being used in the curation work flow at WormBase for automatic association of newly published papers with ten data types including RNAi, antibody, phenotype, gene regulation, mutant allele sequence, gene expression, gene product interaction, overexpression phenotype, gene interaction, and gene structure correction. Conclusions Our methods are applicable to a variety of data types with training set containing several hundreds to a few thousand documents. It is completely automatic and, thus can be readily incorporated to different workflow at different literature-based databases. We believe that the work presented here can contribute greatly to the tremendous task of automating the important yet labor-intensive biocuration effort. PMID:22280404

Curation of information from bioscience literature into biological knowledge databases is a crucial way of capturing experimental information in a computable form. During the biocuration process, a critical first step is to identify from all published literature the papers that contain results for a specific data type the curator is interested in annotating. This step normally requires curators to manually examine many papers to ascertain which few contain information of interest and thus, is usually time consuming. We developed an automatic method for identifying papers containing these curation data types among a large pool of published scientific papers based on the machine learning method Support Vector Machine (SVM). This classification system is completely automatic and can be readily applied to diverse experimental data types. It has been in use in production for automatic categorization of 10 different experimental datatypes in the biocuration process at WormBase for the past two years and it is in the process of being adopted in the biocuration process at FlyBase and the Saccharomyces Genome Database (SGD). We anticipate that this method can be readily adopted by various databases in the biocuration community and thereby greatly reducing time spent on an otherwise laborious and demanding task. We also developed a simple, readily automated procedure to utilize training papers of similar data types from different bodies of literature such as C. elegans and D. melanogaster to identify papers with any of these data types for a single database. This approach has great significance because for some data types, especially those of low occurrence, a single corpus often does not have enough training papers to achieve satisfactory performance. We successfully tested the method on ten data types from WormBase, fifteen data types from FlyBase and three data types from Mouse Genomics Informatics (MGI).

Network meta-analyses (NMAs) aim to rank the benefits (or harms) of interventions, based on all available randomized controlled trials. Thus, the identification of relevant data is critical. We assessed the conduct of the literature searches in NMAs. Published NMAs were retrieved by searching electronic bibliographic databases and other sources. Two independent reviewers selected studies and five trained reviewers abstracted data regarding literature searches, in duplicate. Search method details were examined using descriptive statistics. Two hundred forty-nine NMAs were included. Eight used previous systematic reviews to identify primary studies without further searching, and five did not report any literature searches. In the 236 studies that used electronic databases to identify primary studies, the median number of databases was 3 (interquartile range: 3-5). MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were the most commonly used databases. The most common supplemental search methods included reference lists of included studies (48%), reference lists of previous systematic reviews (40%), and clinical trial registries (32%). None of these supplemental methods was conducted in more than 50% of the NMAs. Literature searches in NMAs could be improved by searching more sources, and by involving a librarian or information specialist. Copyright © 2014 Elsevier Inc. All rights reserved.

Automated detection of records in biological sequence databases that are inconsistent with the literature.

We investigate and analyse the data quality of nucleotide sequence databases with the objective of automatic detection of data anomalies and suspicious records. Specifically, we demonstrate that the published literature associated with each data record can be used to automatically evaluate its quality, by cross-checking the consistency of the key content of the database record with the referenced publications. Focusing on GenBank, we describe a set of quality indicators based on the relevance paradigm of information retrieval (IR). Then, we use these quality indicators to train an anomaly detection algorithm to classify records as "confident" or "suspicious". Our experiments on the PubMed Central collection show assessing the coherence between the literature and database records, through our algorithms, is an effective mechanism for assisting curators to perform data cleansing. Although fewer than 0.25% of the records in our data set are known to be faulty, we would expect that there are many more in GenBank that have not yet been identified. By automated comparison with literature they can be identified with a precision of up to 10% and a recall of up to 30%, while strongly outperforming several baselines. While these results leave substantial room for improvement, they reflect both the very imbalanced nature of the data, and the limited explicitly labelled data that is available. Overall, the obtained results show promise for the development of a new kind of approach to detecting low-quality and suspicious sequence records based on literature analysis and consistency. From a practical point of view, this will greatly help curators in identifying inconsistent records in large-scale sequence databases by highlighting records that are likely to be inconsistent with the literature.

Scheele, Tina Hunter; Pruitt, Rosanne; Johnson, Arlene; Xu, Yu

2011-01-01

Because of cultural differences and language barriers, some Asian nursing students who speak English as a second language (ESL) have not realized their full potential and career goals. Based on an exhaustive search through existing electronic databases in health sciences, this article synthesizes the published literature between 1980 and 2010 on this subgroup of nursing students in four domains: conceptual frameworks, language and communication, support and infrastructure, and instructional strategies. However, some of the classic works were published before 1980. Findings indicate that a body of literature on ESL nursing students has emerged in the last decades, with several limitations. Based on this review, implications for future educational practice and research are elaborated, with an emphasis on an evidence-based approach.

To investigate the distribution and hot spots of literatures on headache by bibliometric analysis in order to provide reference for further study. Literatures that contained headache or migraine in text words published in 2011 in PubMed databases (www.ncbi.nlm.nih.gov/Pubmed) were searched. Journals, countries and subjects were bibliometrically analysed. There were 3683 papers involved to headache published in PubMed in 2011, of which 1527 papers were on headache research. The number of papers on headache research published by USA was the most followed by Italy and Germany (USA 23.25%, Italy 10.74%, Germany 5.83%). The mainly studied subjects were therapy (29.60%), pathophysiology (18.66%) and etiology (16.31%). 14.86% papers published in Cephalalgia, which is one of the most important journals, reported negative results. The emphasis of headache research was on migraine. Therapy, pathophysiology and etiology were the hot spot. Literatures with negative result attracted authors to give the more attention.

To evaluate the levels of the Chinese literature published by the schistosomiasis control institutions of 17 municipal cities of Hubei Province. The related literature published from 2008 to 2012 was searched from the databases of CNKI, VIP and Wanfang and then screened by the exclusion criteria. NoteExpress and Excel softwares were applied to collect the literature and carry out the bibliometric analysis. A total of 168 papers were included and the schistosomiasis control institutes of Jingzhou City and Wuhan City had the highest amount. The literature was mainly published in Chinese Journal of Schistosomiasis Control and Journal of Public Health and Preventive Medicine. The comprehensive influence indexes of the schistosomiasis control institutes of Jingzhou, Wuhan and Qianjiang cities were higher. The schistosomiasis control institutes of Jingzhou City had an extensive content of literature while Wuhan was mainly focused on epidemiology, case report and Oncomelania hupensis snail control. The research of schistosomiasis in each municipal city has an extensive content and the research capacity of the schistosomiasis control institute of Jingzhou City is relatively outstanding.

We conducted a literature review on adverse drug reactions (ADRs) related to 33 kinds of traditional Chinese medicine injections (CMIs) on China's National Essential medicines List (2004 edition). We aimed to retrieve basic ADR information, identify trends related to CMIs, and provide evidence for the research, development, and application of CMIs. We electronically searched the Chinese Biomedical Literature Database (CBM, January 1978-April 2009), the China National Knowledge Infrastructure Database (CNKI, January 1979-April 2009), the Chinese Science and Technology Periodical Database (January 1989-April 2009) and the Traditional Chinese Medicine Database (January 1984-April 2009). We used the terms of 'adverse drug reaction', 'adverse event', 'side effects', 'side reaction', 'toxicity', and 'Chinese medicine injections', as well as the names of the 33 CMIs to search. We also collected CMI-related ADR reports and regulations from the Chinese Food and Drug Administration's 'Newsletter of Adverse Drug Reactions' (Issue 1 to 22). Then we descriptively analyzed all the articles by year published, periodical, and study design. We also analyzed regulations relevants to ADRs. (1) We found 5405 relevant citations, of which 1010 studies met the eligibility criteria. (2) The rate of publishing of research articles on CMI-linked ADRs has risen over time. (3) The included 1010 articles were scattered among 297 periodicals. Of these, 55 journals on pharmaceutical medicine accounted for 39.5% of the total (399/1010); the 64 journals on traditional Chinese medicine, accounted for only 19.5% (197/1010). Only 22 periodicals with relevant articles were included on the core journals of the Beijing University List (2008 edition); these published 129 articles (12.8% of the included articles). (4) The relevant articles consisted of 348 case reports (34.5%), 254 case series (25.2%), 119 reviews (11.8%), 116 randomized controlled trials (11.5%), 78 cross-sectional studies (7.7%), 61 literature analyses of ADR (6.0%), and 28 non-randomized controlled clinical studies (2.8%). (5) Three journals, Adverse Drug Reactions Journal, China Medical Herald, and Chinese Pharmaceuticals, together published 12.3% of the included literature. (6) The most commonly-reported CMI-related ADRs were to Shuanghuanglian, Qingkailing, and Yuxingcao injections, each of which had ADRs mentioned in more than 200 articles. Four of the five CMIs with the most ADR reports (Shuanghuanglian, Ciwujia, Yuxingcao, and Yinzhihuang injections) had been suspended use or sale in the market. (1) Articles published on CMI-related ADRs increased over time, but overall the research is of low quality and is scattered through a large number of sources. (2) Four CMIs (Shuanghuanglian, Ciwujia, Yuxingcao, and Yinzhihuang injections) had been suspended for clinical use or sale. (3) There is an urgent need for a clear standard to grade ADRs of CMIs in order to better risk manage. (4) It is necessary to continually re-evaluate the safety of CMIs and to promote rational use of CMIs. © 2010 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

Antisperm antibodies and fertility association.

Restrepo, B; Cardona-Maya, W

2013-10-01

To evaluate the relation between antisperm antibodies (ASA) and human fertility by reviewing the scientific literature of the last 45 years. We carried out a review of scientific literature about antisperm antibodies and infertility published in spanish or english in databases as Pubmed, Medline, Scielo, some books and another gray literature include information related to this review and that is published in the last 45 years. Infertile couples suffer infertility by immunological mechanisms mainly by the presence of antisperm antibodies ASA in blood, semen or cervicovaginal secretions; the formation of ASA in men and women may be associated with disturbance in immunomodulatory mechanisms that result in functional impairment of sperm and thus its inability to fertilize the oocyte. Immunological infertility caused by ASA is the result of interference of these antibodies in various stages of fertilization process, inhibiting the ability of interaction between sperm and oocyte.

2018-05-04

Recently, public health has acknowledged racism as a social determinant of health. Much evidence exists on the impact of individual-level racism and discrimination, with little to no examination of racism from the standpoint of systems and structures. The purpose of this systematic literature review is to analyze the extent to which public health currently addresses systemic racism in the published literature. Utilizing the PRISMA guidelines, this review examines three widely used databases to examine published literature covering the topic as well as implications for future research and practice. A total of 85 articles were included in the review analysis after meeting study criteria. Across numerous articles, the terms racism and systemic racism are largely absent. A critical need exists for an examination of the historical impact of systemic racism on the social determinants of health and health of marginalized populations.

Background Clinical trials that end prematurely (or “terminate”) raise financial, ethical, and scientific concerns. The extent to which the results of such trials are disseminated and the reasons for termination have not been well characterized. Methods and Findings A cross-sectional, descriptive study of terminated clinical trials posted on the ClinicalTrials.gov results database as of February 2013 was conducted. The main outcomes were to characterize the availability of primary outcome data on ClinicalTrials.gov and in the published literature and to identify the reasons for trial termination. Approximately 12% of trials with results posted on the ClinicalTrials.gov results database (905/7,646) were terminated. Most trials were terminated for reasons other than accumulated data from the trial (68%; 619/905), with an insufficient rate of accrual being the lead reason for termination among these trials (57%; 350/619). Of the remaining trials, 21% (193/905) were terminated based on data from the trial (findings of efficacy or toxicity) and 10% (93/905) did not specify a reason. Overall, data for a primary outcome measure were available on ClinicalTrials.gov and in the published literature for 72% (648/905) and 22% (198/905) of trials, respectively. Primary outcome data were reported on the ClinicalTrials.gov results database and in the published literature more frequently (91% and 46%, respectively) when the decision to terminate was based on data from the trial. Conclusions Trials terminate for a variety of reasons, not all of which reflect failures in the process or an inability to achieve the intended goals. Primary outcome data were reported most often when termination was based on data from the trial. Further research is needed to identify best practices for disseminating the experience and data resulting from terminated trials in order to help ensure maximal societal benefit from the investments of trial participants and others involved with the study.

Obesity, type 2 diabetes and dental caries are all major public health problems in the UK, with significant costs to the healthcare service. We aim to conduct a systematic review to summarise the evidence on the effectiveness of product reformulation measures to reduce the sugar content of food and drink on the population's sugar consumption and health. Electronic database will be systematically searched using a combination of terms, tailored to optimise sensitivity, specificity, and the syntax and functionality of each database. The databases searched will include the Cochrane Library, EMBASE, MEDLINE (Ovid) and Scopus. The bibliographies of those papers that match inclusion criteria will be searched by hand to identify any further, relevant references, which will be subject to the same screening and selection process. The database search results will be supplemented by hand searches. In addition to the peer-reviewed literature, a number of grey literature searches will be undertaken using the broad search terms 'sugar' and 'food' or 'drink' and 'reduction', these searches will include key government and organisation websites as well as general searches in Google. The selection of the studies, data collection and quality appraisal will be performed independently by 2 reviewers. Data will be initially analysed through a narrative synthesis method. If a subset of data we analyse appears comparable, we will investigate the possibility of performing a meta-analysis. Ethics approval will not be required as this is a protocol for a systematic review. The findings will be disseminated widely through conference presentations and published in a peer-reviewed journal.

2017-05-01

To assess the quality of integrative medicine clinical practice guidelines (CPGs) published before 2014. A systematic search of the scientific literature published before 2014 was conducted to select integrative medicine CPGs. Four major Chinese integrated databases and one guideline database were searched: the Chinese Biomedical Literature Database (CBM), the China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data, and the China Guideline Clearinghouse (CGC). Four reviewers independently assessed the quality of the included guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument. Overall consensus among the reviewers was assessed using the intra-class correlation coefficient (ICC). A total of 41 guidelines published from 2003 to 2014 were included. The overall consensus among the reviewers was good [ICC: 0.928; 95% confifi dence interval (CI): 0.920 to 0.935]. The scores on the 6 AGREE domains were: 17% for scope and purpose (range: 6% to 32%), 11% for stakeholder involvement (range: 0 to 24%), 10% for rigor of development (range: 3% to 22%), 39% for clarity and presentation (range: 25% to 64%), 11% for applicability (range: 4% to 24%), and 1% for editorial independence (range: 0 to 15%). The quality of integrative medicine CPGs was low, the development of integrative medicine CPGs should be guided by systematic methodology. More emphasis should be placed on multi-disciplinary guideline development groups, quality of evidence, management of funding and conflfl icts of interest, and guideline updates in the process of developing integrative medicine CPGs in China.

2015-03-01

The aims of the present systematic literature analysis were to evaluate, over a 10-year period, the trend of the proportion of RCT, SR, MA published on endodontic surgery, and to investigate if the impact factor (IF) of the main endodontic Journals correlates with the proportion of RCT, SR, MA they publish. An electronic search of the RCT, SR and MA published on the topic "endodontic surgery" from 2001 to 2010 was performed on Medline and Cochrane CENTRAL database using specific search terms combined with Boolean operators. Endodontic Journals impact factor was retrieved by the Thomson Scientific database. The proportion of each study type over the total number of articles on endodontic surgery published per year was estimated. The correlation between the number of high-evidence level studies published on the main endodontic Journals and the IF of such Journals per year was estimated. From a total of 900 articles published in 2001-2010 on endodontic surgery, there were 114 studies of high evidence level. A significant increase of the proportion of either RCT, SR and MA over the years was found. A modest to unclear correlation was found between the Journal IF and the number of high-evidence articles published. There is a positive trend over the years among researchers in performing studies of good quality in endodontic surgery. The impact factor of endodontic Journals is not consistently influenced by publication of high-evidence level articles. Copyright © 2015 Elsevier Inc. All rights reserved.

To determine the accessibility and currency of delirium guidelines, guideline summary papers and evaluation studies, and critically appraise guideline quality. Systematic literature search for formal guidelines (in English or French) with focus on delirium assessment and/or management in adults (≥18 years), guideline summary papers and evaluation studies.Full appraisal of delirium guidelines published between 2008 and 2013 and obtaining a 'Rigour of Development' domain screening score cut-off of >40% using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Multiple bibliographic databases, guideline organisation databases, complemented by a grey literature search. 3327 database citations and 83 grey literature links were identified. A total of 118 retrieved delirium guidelines and related documents underwent full-text screening. A final 21 delirium guidelines (with 10 being >5 years old), 12 guideline summary papers and 3 evaluation studies were included. For 11 delirium guidelines published between 2008 and 2013, the screening AGREE II 'Rigour' scores ranged from 3% to 91%, with seven meeting the cut-off score of >40%. Overall, the highest rating AGREE II domains were 'Scope and Purpose' (mean 80.1%, range 64-100%) and 'Clarity and Presentation' (mean 76.7%, range 38-97%). The lowest rating domains were 'Applicability' (mean 48.7%, range 8-81%) and 'Editorial Independence' (mean 53%, range 2-90%). The three highest rating guidelines in the 'Applicability' domain incorporated monitoring criteria or audit and costing templates, and/or implementation strategies. Delirium guidelines are best sourced by a systematic grey literature search. Delirium guideline quality varied across all six AGREE II domains, demonstrating the importance of using a formal appraisal tool prior to guideline adaptation and implementation into clinical settings. Adding more knowledge translation resources to guidelines may improve their practical application and effective monitoring. More delirium guideline evaluation studies are needed to determine their effect on clinical practice. Published by the BMJ Publishing Group Limited.

Population groups: indexing, coverage, and retrieval effectiveness of ethnically related health care issues in health sciences databases.

PubMed Central

Efthimiadis, E N; Afifi, M

1996-01-01

OBJECTIVES: This study examined methods of accessing (for indexing and retrieval purposes) medical research on population groups in the major abstracting and indexing services of the health sciences literature. DESIGN: The study of diseases in specific population groups is facilitated by the indexing of both diseases and populations in a database. The MEDLINE, PsycINFO, and Embase databases were selected for the study. The published thesauri for these databases were examined to establish the vocabulary in use. Indexing terms were identified and examined as to their representation in the current literature. Terms were clustered further into groups thought to reflect an end user's perspective and to facilitate subsequent analysis. The medical literature contained in the three online databases was searched with both controlled vocabulary and natural language terms. RESULTS: The three thesauri revealed shallow pre-coordinated hierarchical structures, rather difficult-to-use terms for post-coordination, and a blurring of cultural, genetic, and racial facets of populations. Post-coordination is difficult because of the system-oriented terminology, which is intended mostly for information professionals. The terminology unintentionally restricts access by the end users who lack the knowledge needed to use the thesauri effectively for information retrieval. CONCLUSIONS: Population groups are not represented adequately in the index languages of health sciences databases. Users of these databases need to be alerted to the difficulties that may be encountered in searching for information on population groups. Information and health professionals may not be able to access the literature if they are not familiar with the indexing policies on population groups. Consequently, the study points to a problem that needs to be addressed, through either the redesign of existing systems or the design of new ones to meet the goals of Healthy People 2000 and beyond.

The appropriate nursing staff mix is imperative to the provision of quality care. Nurse staffing levels and staff mix vary from country to country, as well as between care settings. Understanding how staffing skill mix impacts patient, organizational, and financial outcomes is critical in order to allow policymakers and clinicians to make evidence-informed staffing decisions. This paper reports on the methodology for creation of an electronic database of studies exploring the effectiveness of Registered Nurses (RNs) on clinical and patient outcomes, organizational and nurse outcomes, and financial outcomes. Comprehensive literature searches were conducted in four electronic databases. Inclusion criteria for the database included studies published from 1946 to 2016, peer-reviewed international literature, and studies focused on RNs in all health-care disciplines, settings, and sectors. Masters-prepared nurse researchers conducted title and abstract screening and relevance review to determine eligibility of studies for the database. High-level analysis was conducted to determine key outcomes and the frequency at which they appeared within the database. Of the initial 90,352 records, a total of 626 abstracts were included within the database. Studies were organized into three groups corresponding to clinical and patient outcomes, organizational and nurse-related outcomes, and financial outcomes. Organizational and nurse-related outcomes represented the largest category in the database with 282 studies, followed by clinical and patient outcomes with 244 studies, and lastly financial outcomes, which included 124 studies. The comprehensive database of evidence for RN effectiveness is freely available at https://rnao.ca/bpg/initiatives/RNEffectiveness. The database will serve as a resource for the Registered Nurses' Association of Ontario, as well as a tool for researchers, clinicians, and policymakers for making evidence-informed staffing decisions. © 2018 The Authors.

Abstract Aim To summarise and critique the research literature about whistleblowing and nurses. Background Whistleblowing is identified as a crucial issue in maintenance of healthcare standards and nurses are frequently involved in whistleblowing events.

Abstract Aim: To summarise and critique the research literature about whistleblowing and nurses. Whistleblowing is identified as a crucial issue in maintenance of healthcare standards and nurses are frequently involved in whistleblowing events. Despite the importance of this issue, to our knowledge an evaluation of this body of the data-based literature has not been undertaken. An integrative literature review approach was used to summarise and critique the research literature. A comprehensive search of five databases including Medline, CINAHL, PubMed and Health Science: Nursing/Academic Edition, and Google, were searched using terms including: 'Whistleblow*,' 'nurs*.' In addition, relevant journals were examined, as well as reference lists of retrieved papers. Papers published during the years 2007-2013 were selected for inclusion. Fifteen papers were identified, capturing data from nurses in seven countries. The findings in this review demonstrate a growing body of research for the nursing profession at large to engage and respond appropriately to issues involving suboptimal patient care or organisational wrongdoing. Nursing plays a key role in maintaining practice standards and in reporting care that is unacceptable although the repercussions to nurses who raise concerns are insupportable. Overall, whistleblowing and how it influences the individual, their family, work colleagues, nursing practice and policy overall, requires further national and international research attention.

Carotenoids have important functions in bacteria, ranging from harvesting light energy to neutralizing oxidants and acting as virulence factors. However, information pertaining to the carotenoids is scattered throughout the literature. Furthermore, information about the genes/proteins involved in the biosynthesis of carotenoids has tremendously increased in the post-genomic era. A web server providing the information about microbial carotenoids in a structured manner is required and will be a valuable resource for the scientific community working with microbial carotenoids. Here, we have created a manually curated, open access, comprehensive compilation of bacterial carotenoids named as ProCarDB- Prokaryotic Carotenoid Database. ProCarDB includes 304 unique carotenoids arising from 50 biosynthetic pathways distributed among 611 prokaryotes. ProCarDB provides important information on carotenoids, such as 2D and 3D structures, molecular weight, molecular formula, SMILES, InChI, InChIKey, IUPAC name, KEGG Id, PubChem Id, and ChEBI Id. The database also provides NMR data, UV-vis absorption data, IR data, MS data and HPLC data that play key roles in the identification of carotenoids. An important feature of this database is the extension of biosynthetic pathways from the literature and through the presence of the genes/enzymes in different organisms. The information contained in the database was mined from published literature and databases such as KEGG, PubChem, ChEBI, LipidBank, LPSN, and Uniprot. The database integrates user-friendly browsing and searching with carotenoid analysis tools to help the user. We believe that this database will serve as a major information centre for researchers working on bacterial carotenoids.

Modern high-throughput screening methods allow researchers to generate large datasets that potentially contain important biological information. However, oftentimes, picking relevant hits from such screens and generating testable hypotheses requires training in bioinformatics and the skills to efficiently perform database mining. There are currently no tools available to general public that allow users to cross-reference their screen datasets with published screen datasets. To this end, we developed CrossCheck, an online platform for high-throughput screen data analysis. CrossCheck is a centralized database that allows effortless comparison of the user-entered list of gene symbols with 16,231 published datasets. These datasets include published data from genome-wide RNAi and CRISPR screens, interactome proteomics and phosphoproteomics screens, cancer mutation databases, low-throughput studies of major cell signaling mediators, such as kinases, E3 ubiquitin ligases and phosphatases, and gene ontological information. Moreover, CrossCheck includes a novel database of predicted protein kinase substrates, which was developed using proteome-wide consensus motif searches. CrossCheck dramatically simplifies high-throughput screen data analysis and enables researchers to dig deep into the published literature and streamline data-driven hypothesis generation. CrossCheck is freely accessible as a web-based application at http://proteinguru.com/crosscheck.

The utilization and impact of the studies published using the National Cancer Database (NCDB) is currently unclear. In this study, we aim to characterize the published studies, and identify relatively unexplored areas for future investigations. A literature search was performed using PubMed in January 2017 to identify all papers published using NCDB data. Characteristics of the publications were extracted. Citation frequencies were obtained through the Web of Science. Three hundred 2 articles written by 230 first authors met the inclusion criteria. The number of publications grew exponentially since 2013, with 108 articles published in 2016. Articles were published in 86 journals. The majority of the published papers focused on digestive system cancer, while bone and joints, eye and orbit, myeloma, mesothelioma, and Kaposi Sarcoma were never studied. Thirteen institutions in the United States were associated with more than 5 publications. The papers have been cited for a total of 9858 times since the publication of the first paper in 1992. Frequently appearing keywords congregated into 3 clusters: "demographics," "treatments and survival," and "statistical analysis method." Even though the main focuses of the articles captured a extremely wide range, they can be classified into 2 main categories: survival analysis and characterization. Other focuses include database(s) analysis and/or comparison, and hospital reporting. The surging interest in the use of NCDB is accompanied by unequal utilization of resources by individuals and institutions. Certain areas were relatively understudied and should be further explored.

To investigate the relationship between extranodal tumor deposits and prognosis in patients with colorectal cancer. The literatures on extranodal tumor deposits and postoperative survival rate in patients with colorectal cancer published at home and abroad from 1990 to 2014 were retrieved in 15 English literature databases such as MEDLINE/PubMed, Web of Science, Directory of Open Access Journals(DOAJ), SpringerLink and Chinese literature databases such as Chinese Biomedical Literature Database CD-ROM, China National Knowledge Infrastructure (CNKI) Database with the internet platform of Yonsei University Library. After screening for inclusion, data extraction and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software. There were 10 studies meeting the inclusion criteria for meta-analysis. The total sample size of the studies was 4 068 cases with ENTD(+) 727 cases, while ENTD(-) 3 341 cases. Meta analysis showed that 5-year overall survival rate and 5-year relapse-free survival rate were significantly lower in ENTD(+) group than those in ENTD(-) group (OR 0.27, 0.23; 95% CI:0.18 to 0.43, 0.16 to 0.34 respectively, both P=0.000); the 5-year overall survival rates were both significantly lower in ENTD(+) group as compared to ENTD(-) group for patients with N0 and N(+) colorectal cancer (both P<0.05). Extranodal tumor deposits is a poor prognostic factor of patients with colorectal cancer.

Abstract The Saccharomyces Genome Database (SGD; http://www.yeastgenome.org) is an expertly curated database of literature-derived functional information for the model organism budding yeast, Saccharomyces cerevisiae. SGD constantly strives to synergize new types of experimental data and bioinformatics predictions with existing data, and to organize them into a comprehensive and up-to-date information resource. The primary mission of SGD is to facilitate research into the biology of yeast and to provide this wealth of information to advance, in many ways, research on other organisms, even those as evolutionarily distant as humans. To build such a bridge between biological kingdoms, SGD is curating data regarding yeast-human complementation, in which a human gene can successfully replace the function of a yeast gene, and/or vice versa. These data are manually curated from published literature, made available for download, and incorporated into a variety of analysis tools provided by SGD. PMID:29140510

Despite the small contribution of LA in the Science Citation Index (SCI), a growing contribution by LA research to international literature has been observed in recent years. Systematic review. To evaluate the scientific contribution of Latin American (LA) Spine Surgeons in the last decade. A literature search of publications by LA spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. The results were limited to articles published from January 2000 to December 2011. The quality of the publication was evaluated with the journal impact factor (IF), Oxford classification and number of citations. This study comprised 320 articles published in the Medline database by LA spine surgeons from 2000 to 2011. In recent years, there has been an increase in the number of publications by LA spine surgeons. It was observed that 38.4% of LA papers were published in LA journals. 46.6% of the articles were published in journals with an IF lower than 1, and there was no statistically significant difference in the number of articles published in journals with a higher IF during the period. Linear-by-linear association analysis demonstrated an improvement in the level of evidence provided by LA articles published in recent years. This study showed a growth in the number of publications in last 12 years by LA spinal surgeons. It is necessary to discuss a way to increase quantity and quality of scientific publications, mainly through a better education in research.

Quantified trends in the history of verbal behavior research

Eshleman, John W.

1991-01-01

The history of scientific research about verbal behavior research, especially that based on Verbal Behavior (Skinner, 1957), can be assessed on the basis of a frequency and celeration analysis of the published and presented literature. In order to discover these quantified trends, a comprehensive bibliographical database was developed. Based on several literature searches, the bibliographic database included papers pertaining to verbal behavior that were published in the Journal of the Experimental Analysis of Behavior, the Journal of Applied Behavior Analysis, Behaviorism, The Behavior Analyst, and The Analysis of Verbal Behavior. A nonbehavioral journal, the Journal of Verbal Learning and Verbal Behavior was assessed as a nonexample comparison. The bibliographic database also included a listing of verbal behavior papers presented at the meetings of the Association for Behavior Analysis. Papers were added to the database if they (a) were about verbal behavior, (b) referenced B.F. Skinner's (1957) book Verbal Behavior, or (c) did both. Because the references indicated the year of publication or presentation, a count per year of them was measured. These yearly frequencies were plotted on Standard Celeration Charts. Once plotted, various celeration trends in the literature became visible, not the least of which was the greater quantity of verbal behavior research than is generally acknowledged. The data clearly show an acceleration of research across the past decade. The data also question the notion that a “paucity” of research based on Verbal Behavior currently exists. Explanations of the acceleration of verbal behavior research are suggested, and plausible reasons are offered as to why a relative lack of verbal behavior research extended through the mid 1960s to the latter 1970s.

Large-scale extraction of accurate drug-disease treatment pairs from biomedical literature for drug repurposing

PubMed Central

2013-01-01

Background A large-scale, highly accurate, machine-understandable drug-disease treatment relationship knowledge base is important for computational approaches to drug repurposing. The large body of published biomedical research articles and clinical case reports available on MEDLINE is a rich source of FDA-approved drug-disease indication as well as drug-repurposing knowledge that is crucial for applying FDA-approved drugs for new diseases. However, much of this information is buried in free text and not captured in any existing databases. The goal of this study is to extract a large number of accurate drug-disease treatment pairs from published literature. Results In this study, we developed a simple but highly accurate pattern-learning approach to extract treatment-specific drug-disease pairs from 20 million biomedical abstracts available on MEDLINE. We extracted a total of 34,305 unique drug-disease treatment pairs, the majority of which are not included in existing structured databases. Our algorithm achieved a precision of 0.904 and a recall of 0.131 in extracting all pairs, and a precision of 0.904 and a recall of 0.842 in extracting frequent pairs. In addition, we have shown that the extracted pairs strongly correlate with both drug target genes and therapeutic classes, therefore may have high potential in drug discovery. Conclusions We demonstrated that our simple pattern-learning relationship extraction algorithm is able to accurately extract many drug-disease pairs from the free text of biomedical literature that are not captured in structured databases. The large-scale, accurate, machine-understandable drug-disease treatment knowledge base that is resultant of our study, in combination with pairs from structured databases, will have high potential in computational drug repurposing tasks.

The Carcinogenic Potency Database (CPDB) is a systematic and unifying analysis of results of chronic, long-term cancer tests. This paper presents a supplemental plot of the CPDB, including 513 experiments on 157 test compounds published in the general literature in 1993 and 1994 and in Technical Reports of the National Toxicology Program in 1995 and 1996. The plot standardizes the experimental results (whether positive or negative for carcinogenicity), including qualitative data on strain, sex, route of compound administration, target organ, histopathology, and author's opinion and reference to the published paper, as well as quantitative data on carcinogenic potency, statistical significance, tumor incidence, dose-response curve shape, length of experiment, duration of dosing, and dose rate. A numerical description of carcinogenic potency, the TD(subscript)50(/subscript), is estimated for each set of tumor incidence data reported. When added to the data published earlier, the CPDB now includes results of 5,620 experiments on 1,372 chemicals that have been reported in 1,250 published papers and 414 National Cancer Institute/National Toxicology Program Technical Reports. The plot presented here includes detailed analyses of 25 chemicals tested in monkeys for up to 32 years by the National Cancer Institute. Half the rodent carcinogens that were tested in monkeys were not carcinogenic, despite usually strong evidence of carcinogenicity in rodents and/or humans. Our analysis of possible explanatory factors indicates that this result is due in part to the fact that the monkey studies lacked power to detect an effect compared to standard rodent bioassays. Factors that contributed to the lack of power are the small number of animals on test; a stop-exposure protocol for model rodent carcinogens; in a few cases, toxic doses that resulted in stoppage of dosing or termination of the experiment; and in a few cases, low doses administered to monkeys or early termination of the experiment even though the doses were not toxic. Among chemicals carcinogenic in both monkeys and rodents, there is some support for target site concordance, but it is primarily restricted to liver tumors. Potency values are highly correlated between rodents and monkeys. The plot in this paper can be used in conjunction with the earlier results published in the CRC Handbook of Carcinogenic Potency and Genotoxicity Databases [Gold LS, Zeiger E, eds. Boca Raton FL:CRC Press, 1997] and with our web site (http://potency.berkeley.edu), which includes a guide to the plot of the database, a complete description of the numerical index of carcinogenic potency (TD50), and a discussion of the sources of data, the rationale for the inclusion of particular experiments and particular target sites, and the conventions adopted in summarizing the literature. Two summary tables permit easy access to the literature of animal cancer tests by target organ and by chemical. For readers using the CPDB extensively, a combined plot on diskette or other format is available from the first author. It includes all results published earlier and in this paper, ordered alphabetically by chemical. A SAS database is also available. PMID:10421768

2014-01-01

As researchers in disability and health conduct systematic reviews with greater frequency, the definition of disability used in these reviews gains importance. Translating a comprehensive conceptual definition of "disability" into an operational definition that utilizes electronic databases in the health sciences is a difficult step necessary for performing systematic literature reviews in the field. Consistency of definition across studies will help build a body of evidence that is comparable and amenable to synthesis. To illustrate a process for operationalizing the World Health Organization's International Classification of Disability, Functioning, and Health concept of disability for MEDLINE, PsycINFO, and CINAHL databases. We created an electronic search strategy in conjunction with a reference librarian and an expert panel. Quality control steps included comparison of search results to results of a search for a specific disabling condition and to articles nominated by the expert panel. The complete search strategy is presented. Results of the quality control steps indicated that our strategy was sufficiently sensitive and specific. Our search strategy will be valuable to researchers conducting literature reviews on broad populations with disabilities. Copyright © 2014 Elsevier Inc. All rights reserved.

There has been a significant increase in the publication of clinical practice guidelines (CPGs) for respiratory diseases in China. However, little is known about the quality and potential impacts of these CPGs. Our objective was to critically evaluate the quality of Chinese CPGs for respiratory diseases that were published in peer-reviewed medical journals. A systematic search of scientific literature published between 1979 and 2013 was undertaken to identify and select CPGs that were related to respiratory diseases. Four Chinese databases (the Chinese Biomedical Literature database [CBM], the China National Knowledge Infrastructure [CNKI], the VIP database, and the WANFANG database) were used. The quality of eligible guidelines was assessed independently by four reviewers using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. The overall agreement among reviewers was evaluated using an intraclass correlation coefficient. A total of 109 guidelines published in 27 medical journals from 1979 to 2013 were evaluated. The overall agreement among reviewers was considered good (intraclass correlation coefficient, 0.838; 95% CI, 0.812-0.862). The scores of the six AGREE domains were low: 57.3% for scope and purpose (range, 4.2%-80.5%), 23.8% for stakeholder involvement (range, 2.8%-54.2%), 7.7% for rigor of development (range, 0%-27.1%), 59.8% for clarity and presentation (range, 22.2%-80.6%), 10.9% for applicability (range, 0%-22.9%), and 0.6% for editorial independence (range, 0%-16.7%). Scores for all guidelines were below 60%, and only three guidelines (2.8%) were recommended for clinical practice with modifications. The quality of the guidelines was low, and stakeholder involvement, rigor of development, applicability, and editorial independence should be considered in the future development of CPGs for respiratory diseases in China.

How to Define Family Meals in "Shokuiku" (Food and Nutrition Education).

Takimoto, Hidemi; Sarukura, Nobuko; Ishikawa-Takata, Kazuko

2015-01-01

The Japanese government has set 11 targets to promote "Shokuiku." However, among the 11 targets, only two targets (frequency of shared family meals and the proportion of breakfast skipping in children and young men) are quantitative goals. The increase in children eating alone is often lamented in the popular media, but the methodology for identifying the status of family meals ("Kyoshoku"), or how the responses should be validated, is rarely discussed. In the current review, we attempt to clarify how a family meal and survey responses are defined, by searching literature published after 2009, using the following keywords: "family meals" or "shared meals," in the PubMed database for English. For literature published in Japanese, we searched the Igakuchuo-Zassi Database and Google Scholar for relevant studies. In the English literature, questions were likely to focus on whether a dinner or any meal was eaten together with family members living together, while Japanese literature was more focused on "breakfast or dinner" eaten together with family members. The response options varied across different studies, such as the number of family meals a week, or the number of days (per week) these family meals were eaten. We found it quite difficult to compare across the studies, as there is no standardized definition or response options for "family meals." Further studies are needed in order to develop a standardized method to assess the current status of "family meals."

The purpose of this scoping review was to identify any available evidence regarding T4 syndrome. Databases were searched from inception through October 2015 and included PubMed, CINAHL, PEDro, Google Scholar, Osteomed-DR; Index to Chiropractic Literature, PROSPERO, and Chiroaccess. All studies with information about T4 syndrome that were published in a peer-reviewed journal or textbook were included. The information was organized in the format of the International Classification of Functioning, Disability, and Health. Studies were ranked using Sackett's levels of evidence. Eight articles met the inclusion criteria. Studied areas included theoretical pathophysiology and symptom etiology, diagnosis, symptoms, treatment, and outcomes of T4 syndrome. The methodological quality of included studies was low. T4 syndrome is a diagnosis of exclusion that appears to be rare. It has been treated conservatively in the literature using mobilization and exercise. There is no high-quality evidence published about T4 syndrome, and we caution clinicians when considering it as a primary means to determine patient care. Copyright © 2016.

Manual therapy is the non-surgical conservative management of musculoskeletal disorders using the practitioner's hands on the patient's body for diagnosing and treating disease. The aim of this study is to systematically review trial-based economic evaluations of manual therapy relative to other interventions used for the management of musculoskeletal diseases. Randomised clinical trials (RCTs) on the economic evaluation of manual therapy for musculoskeletal diseases will be included in the review. The following databases will be searched from their inception: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Econlit, Mantis, Index to Chiropractic Literature, Science Citation Index, Social Science Citation Index, Allied and Complementary Medicine Database (AMED), Cochrane Database of Systematic Reviews (CDSR), National Health Service Database of Abstracts of Reviews of Effects (NHS DARE), National Health Service Health Technology Assessment Database (NHS HTA), National Health Service Economic Evaluation Database (NHS EED), CENTRAL, five Korean medical databases (Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Service System (RISS), DBPIA, Korean Traditional Knowledge Portal (KTKP) and KoreaMed) and three Chinese databases (China National Knowledge Infrastructure (CNKI), VIP and Wanfang). The evidence for the cost-effectiveness, cost-utility and cost-benefit of manual therapy for musculoskeletal diseases will be assessed as the primary outcome. Health-related quality of life and adverse effects will be assessed as secondary outcomes. We will critically appraise the included studies using the Cochrane risk of bias tool and the Drummond checklist. Results will be summarised using Slavin's qualitative best-evidence synthesis approach. The results of the study will be disseminated via a peer-reviewed journal and/or conference presentations.

Polisena, Julie; Forster, Alan J; Cimon, Karen; Rabb, Danielle

2013-10-10

Post-marketing surveillance (PMS) may identify rare serious incidents or adverse events due to the long-term use of a medical device, which was not captured in the pre-market process. Percutaneous transluminal coronary angioplasty (PTCA) is a non-surgical procedure that uses a balloon-tipped catheter to enlarge a narrowed artery. In 2011, 1,942 adverse event reports related to the use of PTCA catheters were submitted to the FDA by the manufacturers, an increase from the 883 reported in 2008. The primary research objective is to conduct a systematic review of the published and grey literature published between 2007 and 2012 for the frequency of incidents, adverse events and malfunctions associated with the use of PTCA catheters in patients with coronary artery disease (CAD). Grey literature has not been commercially published. We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and PubMed for medical literature on PMS for PTCA catheters in patients with CAD published between January 2007 and July 2012. We also searched the grey literature. This review included 11 studies. The in-hospital adverse events reported were individual cases of myocardial infarction and hematoma. In studies of patients with coronary perforation, more patients with balloon angioplasty were identified compared with patients who required stenting. Our systematic review illustrates that the volume and quality of PMS studies associated with the use of PTCA catheters in patients with CAD are low in the published and grey literature, and may not be useful sources of information for decisions on safety. In most studies, the objectives were not to monitor the long-term safety of the use of PTCA catheters in clinical practice. Future studies can explore the strengths and limitations of PMS databases administered by regulatory authorities.

The economy of China continues to boom and so have its biomedical research and related publishing activities. Several so-called neglected tropical diseases that are most common in the developing world are still rampant or even emerging in some parts of China. The purpose of this article is to document the significant research potential from the Chinese biomedical bibliographic databases. The research contributions from China in the epidemiology and control of schistosomiasis provide an excellent illustration. We searched two widely used databases, namely China National Knowledge Infrastructure (CNKI) and VIP Information (VIP). Employing the keyword "Schistosoma" () and covering the period 1990–2006, we obtained 10,244 hits in the CNKI database and 5,975 in VIP. We examined 10 Chinese biomedical journals that published the highest number of original research articles on schistosomiasis for issues including languages and open access. Although most of the journals are published in Chinese, English abstracts are usually available. Open access to full articles was available in China Tropical Medicine in 2005/2006 and is granted by the Chinese Journal of Parasitology and Parasitic Diseases since 2003; none of the other journals examined offered open access. We reviewed (i) the discovery and development of antischistosomal drugs, (ii) the progress made with molluscicides and (iii) environmental management for schistosomiasis control in China over the past 20 years. In conclusion, significant research is published in the Chinese literature, which is relevant for local control measures and global scientific knowledge. Open access should be encouraged and language barriers removed so the wealth of Chinese research can be more fully appreciated by the scientific community. PMID:18826598

To undertake a review of the quantitative research literature, to determine emergency staff and public attitudes, to support the implementation and practice of family presence during resuscitation in the emergency department. FPDR although endorsed by numerous resuscitation councils, cardiac, trauma and emergency associations, continues to be topical, the extent to which it is implemented and practiced remains unclear. A review of the quantitative studies published between 1992 and October 2011 was undertaken using the following databases: CINAHL, Ovid Medline, PSYCHINFO, Pro-Quest, Theses Database, Cochrane, and Google Scholar search engine. The primary search terms were 'family presence', and 'resuscitation'. The final studies included in this paper were appraised using the Critical Appraisal Skills Programme criteria. Fourteen studies were included in this literature review. These included quantitative descriptive designs, pre and post-test designs and one randomized controlled trial (RCT). The studies were divided into three main research areas; investigation of emergency staff attitudes and opinions, family and general public attitudes, and four papers evaluating family presence programs in the emergency department. Studies published prior to 2000 were included in the background. FPDR in the emergency department is well recognised and documented among policy makers, the extent in which it is implemented and practiced remains unclear. Further research is needed to assess how emergency staff are educated and trained in order to facilitate family presence during resuscitation attempts. Copyright © 2012. Published by Elsevier Ltd.

Health economic analyses in medical nutrition: a systematic literature review.

PubMed

Walzer, Stefan; Droeschel, Daniel; Nuijten, Mark; Chevrou-Séverac, Hélène

2014-01-01

Medical nutrition is a specific nutrition category either covering specific dietary needs and/or nutrient deficiency in patients or feeding patients unable to eat normally. Medical nutrition is regulated by a specific bill in Europe and in the US, with specific legislation and guidelines, and is provided to patients with special nutritional needs and indications for nutrition support. Therefore, medical nutrition products are delivered by medical prescription and supervised by health care professionals. Although these products have existed for more than 2 decades, health economic evidence of medical nutrition interventions is scarce. This research assesses the current published health economic evidence for medical nutrition by performing a systematic literature review related to health economic analysis of medical nutrition. A systematic literature search was done using standard literature databases, including PubMed, the Health Technology Assessment Database, and the National Health Service Economic Evaluation Database. Additionally, a free web-based search was conducted using the same search terms utilized in the systematic database search. The clinical background and basis of the analysis, health economic design, and results were extracted from the papers finally selected. The Drummond checklist was used to validate the quality of health economic modeling studies and the AMSTAR (A Measurement Tool to Assess Systematic Reviews) checklist was used for published systematic reviews. Fifty-three papers were identified and obtained via PubMed, or directly via journal webpages for further assessment. Thirty-two papers were finally included in a thorough data extraction procedure, including those identified by a "gray literature search" utilizing the Google search engine and cross-reference searches. Results regarding content of the studies showed that malnutrition was the underlying clinical condition in most cases (32%). In addition, gastrointestinal disorders (eg, surgery, cancer) were often analyzed. In terms of settings, 56% of papers covered inpatients, whereas 14 papers (44%) captured outpatients, including patients in community centers. Interestingly, in comparison with the papers identified overall, very few health economic models were found. Most of the articles were modeling analyses and economic trials in different design settings. Overall, only eight health economic models were published and were validated applying the Drummond checklist. In summary, most of the models included were carried out to quite a high standard, although some areas were identified for further improvement. Of the two systematic health economic reviews identified, one achieved the highest quality score when applying the AMSTAR checklist. The reasons for finding only a few modeling studies but quite a large number of clinical trials with health economic endpoints, might be different. Until recently, health economics has not been required for reimbursement or coverage decisions concerning medical nutrition interventions. Further, there might be specifics of medical nutrition which might not allow easy modeling and consequently explain the limited uptake so far. The health economic data on medical nutrition generated and published is quite ample. However, it has been primarily based on database analysis and clinical studies. Only a few modeling analyses have been carried out, indicating a need for further research to understand the specifics of medical nutrition and their applicability for health economic modeling.

Abstract Background: The utilization and impact of the studies published using the National Cancer Database (NCDB) is currently unclear. In this study, we aim to characterize the published studies, and identify relatively unexplored areas for future investigations. Methods: A literature search was performed using PubMed in January 2017 to identify all papers published using NCDB data. Characteristics of the publications were extracted. Citation frequencies were obtained through the Web of Science. Results: Three hundred 2 articles written by 230 first authors met the inclusion criteria. The number of publications grew exponentially since 2013, with 108 articles published in 2016. Articles were published in 86 journals. The majority of the published papers focused on digestive system cancer, while bone and joints, eye and orbit, myeloma, mesothelioma, and Kaposi Sarcoma were never studied. Thirteen institutions in the United States were associated with more than 5 publications. The papers have been cited for a total of 9858 times since the publication of the first paper in 1992. Frequently appearing keywords congregated into 3 clusters: “demographics,” “treatments and survival,” and “statistical analysis method.” Even though the main focuses of the articles captured a extremely wide range, they can be classified into 2 main categories: survival analysis and characterization. Other focuses include database(s) analysis and/or comparison, and hospital reporting. Conclusion: The surging interest in the use of NCDB is accompanied by unequal utilization of resources by individuals and institutions. Certain areas were relatively understudied and should be further explored. PMID:29489679

National Geochronological Database

Revised by Sloan, Jan; Henry, Christopher D.; Hopkins, Melanie; Ludington, Steve; Original database by Zartman, Robert E.; Bush, Charles A.; Abston, Carl

2003-01-01

The National Geochronological Data Base (NGDB) was established by the United States Geological Survey (USGS) to collect and organize published isotopic (also known as radiometric) ages of rocks in the United States. The NGDB (originally known as the Radioactive Age Data Base, RADB) was started in 1974. A committee appointed by the Director of the USGS was given the mission to investigate the feasibility of compiling the published radiometric ages for the United States into a computerized data bank for ready access by the user community. A successful pilot program, which was conducted in 1975 and 1976 for the State of Wyoming, led to a decision to proceed with the compilation of the entire United States. For each dated rock sample reported in published literature, a record containing information on sample location, rock description, analytical data, age, interpretation, and literature citation was constructed and included in the NGDB. The NGDB was originally constructed and maintained on a mainframe computer, and later converted to a Helix Express relational database maintained on an Apple Macintosh desktop computer. The NGDB and a program to search the data files were published and distributed on Compact Disc-Read Only Memory (CD-ROM) in standard ISO 9660 format as USGS Digital Data Series DDS-14 (Zartman and others, 1995). As of May 1994, the NGDB consisted of more than 18,000 records containing over 30,000 individual ages, which is believed to represent approximately one-half the number of ages published for the United States through 1991. Because the organizational unit responsible for maintaining the database was abolished in 1996, and because we wanted to provide the data in more usable formats, we have reformatted the data, checked and edited the information in some records, and provided this online version of the NGDB. This report describes the changes made to the data and formats, and provides instructions for the use of the database in geographic information system (GIS) applications. The data are provided in .mdb (Microsoft Access), .xls (Microsoft Excel), and .txt (tab-separated value) formats. We also provide a single non-relational file that contains a subset of the data for ease of use.

Plant Reactome (http://plantreactome.gramene.org/) is a free, open-source, curated plant pathway database portal, provided as part of the Gramene project. The database provides intuitive bioinformatics tools for the visualization, analysis and interpretation of pathway knowledge to support genome annotation, genome analysis, modeling, systems biology, basic research and education. Plant Reactome employs the structural framework of a plant cell to show metabolic, transport, genetic, developmental and signaling pathways. We manually curate molecular details of pathways in these domains for reference species Oryza sativa (rice) supported by published literature and annotation of well-characterized genes. Two hundred twenty-two rice pathways, 1025 reactions associated with 1173 proteins, 907 small molecules and 256 literature references have been curated to date. These reference annotations were used to project pathways for 62 model, crop and evolutionarily significant plant species based on gene homology. Database users can search and browse various components of the database, visualize curated baseline expression of pathway-associated genes provided by the Expression Atlas and upload and analyze their Omics datasets. The database also offers data access via Application Programming Interfaces (APIs) and in various standardized pathway formats, such as SBML and BioPAX. PMID:27799469

The potential for disasters exists in all communities. To mitigate the potential catastrophes that confront humanity in the new millennium, an evidence-based approach to disaster management is required urgently. This study moves toward such an evidence-based approach by identifying peer-reviewed publications following a range of disasters and events over the past three decades. Peer-reviewed, event-specific literature was identified using a comprehensive search of the electronically indexed database, MEDLINE (1956-January 2009). An extended comprehensive search was conducted for one event to compare the event-specific literature indexed in MEDLINE to other electronic databases (EMBASE, CINAHL, AMED, CENTRAL, Psych Info, Maternity and Infant Care, EBM Reviews). Following 25 individual disasters or overwhelming crises, a total of 2,098 peer-reviewed, event-specific publications were published in 789 journals (652 publications following disasters/events caused by natural hazards, 966 following human-made/technological disasters/events, and 480 following conflict/complex humanitarian events).The event with the greatest number of peer-reviewed, event-specific publications was the 11 September 2001 terrorist attacks (686 publications). Prehospital and Disaster Medicine published the greatest number of peer-reviewed, event-specific publications (54), followed by Journal of Traumatic Stress (42), Military Medicine (40), and Psychiatric Services (40). The primary topics of event-specific publications were mental health, medical health, and response. When an extended, comprehensive search was conducted for one event, 75% of all peer-reviewed, event-specific publications were indexed in MEDLINE. A broad range of multi-disciplinary journals publish peer reviewed, event-specific publications. While the majority of peer-reviewed, event-specific literature is indexed in MEDLINE, comprehensive search strategies should include EMBASE to increase yield.

Background Despite the small contribution of LA in the Science Citation Index (SCI), a growing contribution by LA research to international literature has been observed in recent years. Study Design Systematic review. Purpose To evaluate the scientific contribution of Latin American (LA) Spine Surgeons in the last decade. Methods A literature search of publications by LA spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. The results were limited to articles published from January 2000 to December 2011. The quality of the publication was evaluated with the journal impact factor (IF), Oxford classification and number of citations. Results This study comprised 320 articles published in the Medline database by LA spine surgeons from 2000 to 2011. In recent years, there has been an increase in the number of publications by LA spine surgeons. It was observed that 38.4% of LA papers were published in LA journals. 46.6% of the articles were published in journals with an IF lower than 1, and there was no statistically significant difference in the number of articles published in journals with a higher IF during the period. Linear-by-linear association analysis demonstrated an improvement in the level of evidence provided by LA articles published in recent years. Conclusions This study showed a growth in the number of publications in last 12 years by LA spinal surgeons. It is necessary to discuss a way to increase quantity and quality of scientific publications, mainly through a better education in research. PMID:24505336

E-cigarettes or electronic nicotine delivery systems (ENDS) have recently attracted considerable attention. Among some individuals there is strong debate and a polarisation of views about the public health benefits versus harms of ENDS. With little regulation, the ENDS market is evolving, and new products are introduced and marketed constantly. Rapid developments in manufacturing, marketing and consumer domains related to ENDS will warrant frequent re-evaluation, based on the state of the evolving science. The purpose of this article is to describe a protocol for an ongoing comprehensive review of the published scientific literature on ENDS. We will undertake a systematic review of published empirical research literature on ENDS using the National Library of Medicine's PubMed electronic database to search for relevant articles. Data from included studies will be extracted into a standardised form, tables with study details and key outcomes for each article will be created, and studies will be synthesised qualitatively. This review synthesises published literature and presents no primary data. Therefore, no ethical approval is required for this study. Subsequent papers will provide greater detail on results, within select categories, that represent gaps in the literature base. Published by the BMJ Publishing Group Limited.

Inadvertently submitting a paper to a journal that is unlikely to publish it is a waste of resources and ultimately delays dissemination of one's research. A high proportion of manuscripts are rejected by their author's first-choice journal. The aim of the present work was to review guidance provided within the literature for journal selection that might minimize the chance of manuscript rejection. We also consider papers that encompass more than one main medical science and describe the selection process that we used with a paper that was published in Cardiovascular Endocrinology . A database search (Embase, PubMed and Medworm) was performed for all articles published in the scientific literature providing guidance on journal selection. Articles were identified that either had journal selection as their principal topic or included journal selection as part of a broader discussion of publishing. The relative performance of four free-to-use, web-based applications that claim to provide guidance on journal selection was compared. The searches identified 286 hits, of which 249 were in English. Of these papers, 16 discussed journal selection and a further 10 articles were identified from citations within the original 16 articles. Only one article described a comprehensive model for submission decision-making. Identification of appropriate candidate journals by various web-based applications was erratic, with the Jane database providing the most robust suggestions. Our work suggests that little attention has been focused in the scientific literature on the mechanisms that authors use to select a journal for their work. Nevertheless, scientists for the most part seem to have a good sense of where their papers are most likely to be accepted. Beyond ensuring that a manuscript fulfils all the target journal's requirements, the literature suggests that it is important to have an objective view of the scientific contribution or 'value' of your work.

To analyse systematic review articles published in the top 10 nursing journals to determine the quality of the methods employed within them. Systematic review is defined as a scientific research method that synthesises high-quality scientific knowledge on a given topic. The number of such reviews in nursing science has increased dramatically during recent years, but their methodological quality has not previously been assessed. A review of the literature using a narrative approach. Ranked impact factor scores for nursing journals were obtained from the Journal Citation Report database of the Institute of Scientific Information (ISI Web of Knowledge). All issues from the years 2009 and 2010 of the top 10 ranked journals were included. CINAHL and MEDLINE databases were searched to locate studies using the search terms 'systematic review' and 'systematic literature review'. A total of 39 eligible studies were identified. Their methodological quality was evaluated through the specific criteria of quality assessment, description of synthesis and strengths and weaknesses reported in the included studies. Most of the eligible systematic reviews included several different designs or types of quantitative study. The majority included a quality assessment, and a total of 17 different criteria were identified. The method of synthesis was mentioned in about half of the reviews, the most common being narrative synthesis. The weaknesses of reviews were discussed, while strengths were rarely highlighted. The methodological quality of the systematic reviews examined varied considerably, although they were all published in nursing journals with a high-impact factor. Despite the fact that systematic reviews are considered the most robust source of research evidence, they vary in methodological quality. This point is important to consider in clinical practice when applying the results to patient care. © 2013 Blackwell Publishing Ltd.

What do searchers find when they look for literature on homosexuality? This question has profound implications for older as well as younger gays in their coming out, as well as in their subsequent identity development. Library records provide credible data to answer the question, since they represent relatively free sources of information, unlike data from bookstores, publishers, and some World Wide Web sites. The records of WorldCat, the world's largest union database of library records, comprise over 30 million records listed in the Online Computer Library Center. For the purposes of the study, 18,757 records listed under "Homosexuality," "Gay Men," and "Gays" were downloaded; records for "Lesbian" and "Lesbians" were not examined. Findings of the study suggest that while there has indeed been considerable growth in terms of the quantity of gay literature produced since 1969, such gains may be offset by the deteriorating quality of cataloging copy, which makes the experience of browsing records a discouraging and confusing one.

Does providing dental services reduce overall health care costs?: A systematic review of the literature.

2018-06-01

The authors conducted a systematic review of the literature to assess the impact of dental treatment on overall health care costs for patients with chronic health conditions and patients who were pregnant. The authors searched multiple databases including MEDLINE, Embase, Web of Science, and Dentistry & Oral Sciences Source from the earliest date available through May 2017. Two reviewers conducted the initial screening of all retrieved titles and abstracts, read the full text of the eligible studies, and conducted data extraction and quality assessment of included studies. The authors found only 3 published studies that examined the effect of periodontal treatment on health care costs using medical and dental claims data from different insurance databases. Findings from the qualitative synthesis of those studies were inconclusive as 1 of the 3 studies showed a cost increase, whereas 2 studies showed a decrease. The small number of studies and their mixed outcomes demonstrate the need for high-quality studies to evaluate the effect of periodontal intervention on overall health care costs.

To perform an overview of literature search strategies in systematic reviews (SRs) published in periodontology and implant dentistry. Two electronic databases (PubMed and Cochrane Database of SRs) were searched, independently and in duplicate, for SRs with meta-analyses on interventions, with the last search performed on 11 November 2012. Manual searches of the reference lists of included SRs and 10 specialty dental journals were conducted. Methodological issues of the search strategies of included SRs were assessed with Cochrane collaboration guidelines and AMSTAR recommendations. The search strategies employed in Cochrane and paper-based SRs were compared. A total of 146 SRs with meta-analyses were included, including 19 Cochrane and 127 paper-based SRs. Some issues, such as "the use of keywords," were reported in most of the SRs (86%). Other issues, such as "search of grey literature" and "language restriction," were not fully reported (34% and 50% respectively). The quality of search strategy reporting in Cochrane SRs was better than that of paper-based SRs for seven of the eight criteria assessed. There is room for improving the quality of reporting of search strategies in SRs in periodontology and implant dentistry, particularly in SRs published in paper-based journals. © 2013 John Wiley & Sons A/S.

When literature searching for systematic reviews, it is good practice to search widely across different information sources. Little is known about the contributions of different publication formats (e.g. journal article and book chapter) and sources, especially for studies of people's views. Studies from four reviews spanning three public health areas (active transport, motherhood and obesity) were analysed in terms of publication formats and the information sources they were identified from. They comprised of 229 studies exploring people's perceptions, beliefs and experiences ('views studies') and were largely qualitative. Although most (61%) research studies were published within journals, nearly a third (29%) were published as research reports and 5% were published in books. The remainder consisted of theses, conference papers and raw datasets. Two-thirds of studies (66%) were located in a total of 19 bibliographic databases, and 15 databases provided studies that were not identified elsewhere. PubMed was a good source for all reviews. Supplementary information sources were important for identifying studies in all publication formats. Undertaking sensitive searches across a range of information sources is essential for locating views studies in all publication formats. We discuss some benefits and challenges of utilising different information sources. Copyright © 2013 John Wiley & Sons, Ltd.

Posture, Musculoskeletal Activities, and Possible Musculoskeletal Discomfort Among Children Using Laptops or Tablet Computers for Educational Purposes: A Literature Review

2014-10-01

Educational ergonomics focuses on the interaction between educational performance and educational design. By improving the design or pointing out the possible problems, educational ergonomics can be utilized to have positive impacts on the student performance and thus on education process. Laptops and tablet computers are becoming widely used by school children and beginning to be used effectively for educational purposes. As the latest generation of laptops and tablet computers are mobile and lightweight compared to conventional personal computers, they support student-centred interaction-based learning. However, these technologies have been introduced into schools with minimal adaptations to furniture or attention to ergonomics. There are increasing reports of an association between increased musculoskeletal (MSK) problems in children and use of such technologies. Although children are among the users of laptops and tablet computers both in their everyday lives and at schools, the literature investigating MSK activities and possible MSK discomfort regarding children using portable technologies is limited. This study reviews the literature to identify published studies that investigated posture, MSK activities, and possible MSK discomfort among children using mobile technologies (laptops or tablet computers) for educational purposes. An electronic search of the literature published in English between January 1994 and January 2014 was performed in several databases. The literature search terms were identified and combined to search the databases. The search results that the resources investigating MSK outcomes of laptop or tablet use of children are very scarce. This review points out the research gaps in this field, and identifying areas for future studies.

Extensive literature exists on public involvement or engagement, but what actual tools or guides exist that are practical, tested and easy to use specifically for initiating and implementing patient and family engagement, is uncertain. No comprehensive review and synthesis of general international published or grey literature on this specific topic was found. A systematic scoping review of published and grey literature is, therefore, appropriate for searching through the vast general engagement literature to identify 'patient/family engagement' tools and guides applicable in health organization decision-making, such as within Alberta Health Services in Alberta, Canada. This latter organization requested this search and review to inform the contents of a patient engagement resource kit for patients, providers and leaders. Search terms related to 'patient engagement', tools, guides, education and infrastructure or resources, were applied to published literature databases and grey literature search engines. Grey literature also included United States, Australia and Europe where most known public engagement practices exist, and Canada as the location for this study. Inclusion and exclusion criteria were set, and include: English documents referencing 'patient engagement' with specific criteria, and published between 1995 and 2011. For document analysis and synthesis, document analysis worksheets were used by three reviewers for the selected 224 published and 193 grey literature documents. Inter-rater reliability was ensured for the final reviews and syntheses of 76 published and 193 grey documents. Seven key themes emerged from the literature synthesis analysis, and were identified for patient, provider and/or leader groups. Articles/items within each theme were clustered under main topic areas of 'tools', 'education' and 'infrastructure'. The synthesis and findings in the literature include 15 different terms and definitions for 'patient engagement', 17 different engagement models, numerous barriers and benefits, and 34 toolkits for various patient engagement and evaluation initiatives. Patient engagement is very complex. This scoping review for patient/family engagement tools and guides is a good start for a resource inventory and can guide the content development of a patient engagement resource kit to be used by patients/families, healthcare providers and administrators.

We created an exposure database of respirable crystalline silica levels in the construction industry from the literature. We extracted silica and dust exposure levels in publications reporting silica exposure levels or quantitative evaluations of control effectiveness published in or after 1990. The database contains 6118 records (2858 of respirable crystalline silica) extracted from 115 sources, summarizing 11,845 measurements. Four hundred and eighty-eight records represent summarized exposure levels instead of individual values. For these records, the reported summary parameters were standardized into a geometric mean and a geometric standard deviation. Each record is associated with 80 characteristics, including information on trade, task, materials, tools, sampling strategy, analytical methods, and control measures. Although the database was constructed in French, 38 essential variables were standardized and translated into English. The data span the period 1974-2009, with 92% of the records corresponding to personal measurements. Thirteen standardized trades and 25 different standardized tasks are associated with at least five individual silica measurements. Trade-specific respirable crystalline silica geometric means vary from 0.01 (plumber) to 0.30 mg/m³ (tunnel construction skilled labor), while tasks vary from 0.01 (six categories, including sanding and electrical maintenance) to 1.59 mg/m³ (abrasive blasting). Despite limitations associated with the use of literature data, this database can be analyzed using meta-analytical and multivariate techniques and currently represents the most important source of exposure information about silica exposure in the construction industry. It is available on request to the research community.

Risk of cancer is determined by a complex interplay of genetic and environmental factors. Although the study of gene-environment interactions (G×E) has been an active area of research, little is reported about the known findings in the literature. To examine the state of the science in G×E research in cancer, we performed a systematic review of published literature using gene-environment or pharmacogenomic flags from two curated databases of genetic association studies, the Human Genome Epidemiology (HuGE) literature finder and Cancer Genome-Wide Association and Meta Analyses Database (CancerGAMAdb), from January 1, 2001, to January 31, 2011. A supplemental search using HuGE was conducted for articles published from February 1, 2011, to April 11, 2013. A 25% sample of the supplemental publications was reviewed. A total of 3,019 articles were identified in the original search. From these articles, 243 articles were determined to be relevant based on inclusion criteria (more than 3,500 interactions). From the supplemental search (1,400 articles identified), 29 additional relevant articles (1,370 interactions) were included. The majority of publications in both searches examined G×E in colon, rectal, or colorectal; breast; or lung cancer. Specific interactions examined most frequently included environmental factors categorized as energy balance (e.g., body mass index, diet), exogenous (e.g., oral contraceptives) and endogenous hormones (e.g., menopausal status), chemical environment (e.g., grilled meats), and lifestyle (e.g., smoking, alcohol intake). In both searches, the majority of interactions examined were using loci from candidate genes studies and none of the studies were genome-wide interaction studies (GEWIS). The most commonly reported measure was the interaction P-value, of which a sizable number of P-values were considered statistically significant (i.e., <0.05). In addition, the magnitude of interactions reported was modest. Observations of published literature suggest that opportunity exists for increased sample size in G×E research, including GWAS-identified loci in G×E studies, exploring more GWAS approaches in G×E such as GEWIS, and improving the reporting of G×E findings.

Computer-aided drug design (CADD) often involves virtual screening (VS) of large compound datasets and the availability of such is vital for drug discovery protocols. We present CamMedNP - a new database beginning with more than 2,500 compounds of natural origin, along with some of their derivatives which were obtained through hemisynthesis. These are pure compounds which have been previously isolated and characterized using modern spectroscopic methods and published by several research teams spread across Cameroon. In the present study, 224 distinct medicinal plant species belonging to 55 plant families from the Cameroonian flora have been considered. About 80 % of these have been previously published and/or referenced in internationally recognized journals. For each compound, the optimized 3D structure, drug-like properties, plant source, collection site and currently known biological activities are given, as well as literature references. We have evaluated the "drug-likeness" of this database using Lipinski's "Rule of Five". A diversity analysis has been carried out in comparison with the ChemBridge diverse database. CamMedNP could be highly useful for database screening and natural product lead generation programs.

To investigate the state of knowledge on emotional intelligence (EI) education in pre-registration nursing programmes. Integrative literature review. CINAHL, Medline, Scopus, ERIC, and Web of Knowledge electronic databases were searched for abstracts published in English between 1992-2014. Data extraction and constant comparative analysis of 17 articles. Three categories were identified: Constructs of emotional intelligence; emotional intelligence curricula components; and strategies for emotional intelligence education. A wide range of emotional intelligence constructs were found, with a predominance of trait-based constructs. A variety of strategies to enhance students' emotional intelligence skills were identified, but limited curricula components and frameworks reported in the literature. An ability-based model for curricula and learning and teaching approaches is recommended. Copyright © 2014. Published by Elsevier Ltd.

According to the declaration of the Budapest Open Access Initiative (OAI) is defined as a editorial model in which access to scientific journal literature and his use are free. Free flow of information allowed by Internet has been the basis of this initiative. The Bethesda and the Berlin declarations, supported by some international agencies, proposes to require researchers to deposit copies of all articles published in a self-archive or an Open Access repository, and encourage researchers to publish their research papers in journals Open Access. This paper reviews the keys of the OAI, with their strengths and controversial aspects; and it discusses the position of databases, search engines and repositories of biomedical information, as well as the attitude of the scientists, publishers and journals. So far the journal Actas Urológicas Españolas (Act Urol Esp) offer their contents on Open Access as On Line in Spanish and English.

Text-based plagiarism in scientific publishing: issues, developments and education.

PubMed

Li, Yongyan

2013-09-01

Text-based plagiarism, or copying language from sources, has recently become an issue of growing concern in scientific publishing. Use of CrossCheck (a computational text-matching tool) by journals has sometimes exposed an unexpected amount of textual similarity between submissions and databases of scholarly literature. In this paper I provide an overview of the relevant literature, to examine how journal gatekeepers perceive textual appropriation, and how automated plagiarism-screening tools have been developed to detect text matching, with the technique now available for self-check of manuscripts before submission; I also discuss issues around English as an additional language (EAL) authors and in particular EAL novices being the typical offenders of textual borrowing. The final section of the paper proposes a few educational directions to take in tackling text-based plagiarism, highlighting the roles of the publishing industry, senior authors and English for academic purposes professionals.

This article describes the methodology of preparation, writing and publishing scientific papers in biomedical journals. given is a concise overview of the concept and structure of the System of biomedical scientific and technical information and the way of biomedical literature retreival from worldwide biomedical databases. Described are the scientific and professional medical journals that are currently published in Bosnia and Herzegovina. Also, given is the comparative review on the number and structure of papers published in indexed journals in Bosnia and Herzegovina, which are listed in the Medline database. Analyzed are three B&H journals indexed in MEDLINE database: Medical Archives (Medicinski Arhiv), Bosnian Journal of Basic Medical Sciences and Medical Gazette (Medicinki Glasnik) in 2010. The largest number of original papers was published in the Medical Archives. There is a statistically significant difference in the number of papers published by local authors in relation to international journals in favor of the Medical Archives. True, the Journal Bosnian Journal of Basic Medical Sciences does not categorize the articles and we could not make comparisons. Journal Medical Archives and Bosnian Journal of Basic Medical Sciences by percentage published the largest number of articles by authors from Sarajevo and Tuzla, the two oldest and largest university medical centers in Bosnia and Herzegovina. The author believes that it is necessary to make qualitative changes in the reception and reviewing of papers for publication in biomedical journals published in Bosnia and Herzegovina which should be the responsibility of the separate scientific authority/ committee composed of experts in the field of medicine at the state level.

We reviewed the literature on transcranial magnetic stimulation and its uses and efficacy in schizophrenia. Multiple sources were examined on transcranial magnetic stimulation efficacy in relieving positive and negative symptoms of schizophrenia. Literature review was conducted via Ovid Medline and PubMed databases. We found multiple published studies and metaanalyses that give evidence that repetitive transcranial magnetic stimulation can have benefit in relieving positive and negative symptoms of schizophrenia, particularly auditory hallucinations. These findings should encourage the psychiatric community to expand research into other applications for which transcranial magnetic stimulation may be used to treat patients with psychiatric disability.

Ross, Jacqueline

2010-04-01

Information literacy, the recognition of information required, and the development of skills for locating, evaluating, and effectively using relevant evidence is needed for evidence-based practice (EBP). The purpose of this study was to examine perianesthesia nurses' perception of searching skills and access to evidence sources. The design was a descriptive, exploratory survey. The sample consisted of ASPAN members (n = 64) and nonmembers (n = 64). The Information Literacy for Evidence-Based Nursing Practice instrument was used. Findings were that ASPAN members read more journal articles, were more proficient with computers, and used Cumulative Index to Nursing and Allied Health Literature (CINAHL) more frequently than nonmembers. The three top barriers to use of research were: lack of understanding of organization or structure of electronic databases, lack of skills to critique and/or synthesize the literature, and difficulty in accessing research materials. In conclusion, education is needed for critiquing literature and understanding electronic databases and research articles to promote EBP in perianesthesia areas. Copyright 2010.

Objectives. This review aims to evaluate the effect of orthodontic therapy on periodontal health. Data. Original articles that reported on the effect of orthodontic therapy on periodontal health were included. The reference lists of potentially relevant review articles were also sought. Sources. A literature search was conducted using the databases, Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies. The search was carried out by using a combined text and the MeSH search strategies: using the key words in different combinations: “periodontal disease,” “orthodontics” and “root resorption.” This was supplemented by hand-searching in peer-reviewed journals and cross-referenced with the articles accessed. Articles published only in English language were included. Letters to the Editor, historical reviews and unpublished articles were not sought. Conclusions. Within the limitations of the present literature review, it was observed that there is a very close inter-relationship between the periodontal health and the outcome of orthodontic therapy.

Poomkottayil, Deepak; Bornstein, Michael M; Sendi, Pedram

2011-01-28

Citation metrics are commonly used as a proxy for scientific merit and relevance. Papers published in English, however, may exhibit a higher citation frequency than research articles published in other languages, though this issue has not yet been investigated from a Swiss perspective where English is not the native language. To assess the impact of publication language on citation frequency we focused on oral surgery papers indexed in PubMed MEDLINE that were published by Swiss Dental Schools between 2002 and 2007. Citation frequency of research papers was extracted from the Institute for Scientific Information (ISI) and Google Scholar database. A univariate and multivariate logistic regression model was used to assess the impact of publication language (English versus German/French) on citation frequency, adjusted for journal impact factor, number of authors and research topic. Papers published in English showed a 6 (ISI database) and 7 (Google Scholar) times higher odds for being cited than research articles published in German or French. Our results suggest that publication language substantially influences the citation frequency of a research paper. Researchers should publish their work in English to render them accessible to the international scientific community.

A Source-based Measurement Database for Occupational Exposure Assessment of Electromagnetic Fields in the INTEROCC Study: A Literature Review Approach

PubMed Central

Vila, Javier; Bowman, Joseph D.; Richardson, Lesley; Kincl, Laurel; Conover, Dave L.; McLean, Dave; Mann, Simon; Vecchia, Paolo; van Tongeren, Martie; Cardis, Elisabeth

Introduction: To date, occupational exposure assessment of electromagnetic fields (EMF) has relied on occupation-based measurements and exposure estimates. However, misclassification due to between-worker variability remains an unsolved challenge. A source-based approach, supported by detailed subject data on determinants of exposure, may allow for a more individualized exposure assessment. Detailed information on the use of occupational sources of exposure to EMF was collected as part of the INTERPHONE-INTEROCC study. To support a source-based exposure assessment effort within this study, this work aimed to construct a measurement database for the occupational sources of EMF exposure identified, assembling available measurements from the scientific literature. Methods: First, a comprehensive literature search was performed for published and unpublished documents containing exposure measurements for the EMF sources identified, a priori as well as from answers of study subjects. Then, the measurements identified were assessed for quality and relevance to the study objectives. Finally, the measurements selected and complementary information were compiled into an Occupational Exposure Measurement Database (OEMD). Results: Currently, the OEMD contains 1624 sets of measurements (>3000 entries) for 285 sources of EMF exposure, organized by frequency band (0 Hz to 300 GHz) and dosimetry type. Ninety-five documents were selected from the literature (almost 35% of them are unpublished technical reports), containing measurements which were considered informative and valid for our purpose. Measurement data and complementary information collected from these documents came from 16 different countries and cover the time period between 1974 and 2013. Conclusion: We have constructed a database with measurements and complementary information for the most common sources of exposure to EMF in the workplace, based on the responses to the INTERPHONE-INTEROCC study questionnaire. This database covers the entire EMF frequency range and represents the most comprehensive resource of information on occupational EMF exposure. It is available at www.crealradiation.com/index.php/en/databases. PMID:26493616

Trypanosoma cruzi, the causative agent of Chagas disease, is transmitted to mammals - including humans - by insect vectors of the subfamily Triatominae. We present the results of a compilation of triatomine occurrence and complementary ecological data that represents the most complete, integrated and updated database (DataTri) available on triatomine species at a continental scale. This database was assembled by collecting the records of triatomine species published from 1904 to 2017, spanning all American countries with triatomine presence. A total of 21815 georeferenced records were obtained from published literature, personal fieldwork and data provided by colleagues. The data compiled includes 24 American countries, 14 genera and 135 species. From a taxonomic perspective, 67.33% of the records correspond to the genus Triatoma, 20.81% to Panstrongylus, 9.01% to Rhodnius and the remaining 2.85% are distributed among the other 11 triatomine genera. We encourage using DataTri information in various areas, especially to improve knowledge of the geographical distribution of triatomine species and its variations in time.

Trypanosoma cruzi, the causative agent of Chagas disease, is transmitted to mammals - including humans - by insect vectors of the subfamily Triatominae. We present the results of a compilation of triatomine occurrence and complementary ecological data that represents the most complete, integrated and updated database (DataTri) available on triatomine species at a continental scale. This database was assembled by collecting the records of triatomine species published from 1904 to 2017, spanning all American countries with triatomine presence. A total of 21815 georeferenced records were obtained from published literature, personal fieldwork and data provided by colleagues. The data compiled includes 24 American countries, 14 genera and 135 species. From a taxonomic perspective, 67.33% of the records correspond to the genus Triatoma, 20.81% to Panstrongylus, 9.01% to Rhodnius and the remaining 2.85% are distributed among the other 11 triatomine genera.

The development and use of healthcare databases accentuates the need for dedicated tools, including validated selection algorithms of cancer diseased patients. As part of the development of the French National Health Insurance System data network REDSIAM, the tumor taskforce established an inventory of national and internal published algorithms in the field of cancer. This work aims to facilitate the choice of a best-suited algorithm. A non-systematic literature search was conducted for various cancers. Results are presented for lung, breast, colon, and rectum. Medline, Scopus, the French Database in Public Health, Google Scholar, and the summaries of the main French journals in oncology and public health were searched for publications until August 2016. An extraction grid adapted to oncology was constructed and used for the extraction process. A total of 18 publications were selected for lung cancer, 18 for breast cancer, and 12 for colorectal cancer. Validation studies of algorithms are scarce. When information is available, the performance and choice of an algorithm are dependent on the context, purpose, and location of the planned study. Accounting for cancer disease specificity, the proposed extraction chart is more detailed than the generic chart developed for other REDSIAM taskforces, but remains easily usable in practice. This study illustrates the complexity of cancer detection through sole reliance on healthcare databases and the lack of validated algorithms specifically designed for this purpose. Studies that standardize and facilitate validation of these algorithms should be developed and promoted. Copyright © 2017. Published by Elsevier Masson SAS.

Hepatitis A and B vaccines are highly effective tools that can greatly reduce infection risk in the bleeding disorder population. Although hepatitis A and B immunization for individuals with bleeding disorders is universally recommended, various advisory bodies often differ with respect to many practical aspects of vaccination. To review the published literature and guidelines and form a practical, comprehensive and consistent approach to hepatitis A and B immunization for individuals with bleeding disorders. We reviewed published immunization guidelines from North American immunization advisory bodies and published statements from North American and international haemophilia advisory bodies. A search of the MEDLINE database was performed to find original published literature pertaining to hepatitis A or B immunization of patients with haemophilia or bleeding disorder patients that provided supporting or refuting evidence for advisory body guidelines. Various advisory bodies' immunization guidelines regarding individuals with bleeding disorders have contradictory statements and often did not clarify issues (e.g. post vaccination surveillance). Published literature addressing immunization in bleeding disorder patients is sparse and mostly examines route of vaccine administration, complications and corresponding antibody response. Although the risk of hepatitis A and B infection is low, the use of simple measures such as vaccination is reasonable and advocated by haemophilia advisory bodies. Following our review of the available literature and North American guidelines, we have developed comprehensive and practical recommendations addressing hepatitis A and B immunization for the bleeding disorder population that may be applicable in Bleeding Disorder clinics.

2018-03-01

The purpose of this literature review is to provide an overview of the information retrieval behaviour of clinical nurses, in terms of the use of databases and other information resources and their frequency of use. Systematic searches carried out in five databases and handsearching were used to identify the studies from 2010 to 2016, with a populations, exposures and outcomes (PEO) search strategy, focusing on the question: In which databases or other information resources do hospital nurses search for evidence based information, and how often? Of 5272 titles retrieved based on the search strategy, only nine studies fulfilled the criteria for inclusion. The studies are from the United States, Canada, Taiwan and Nigeria. The results show that hospital nurses' primary choice of source for evidence based information is Google and peers, while bibliographic databases such as PubMed are secondary choices. Data on frequency are only included in four of the studies, and data are heterogenous. The reasons for choosing Google and peers are primarily lack of time; lack of information; lack of retrieval skills; or lack of training in database searching. Only a few studies are published on clinical nurses' retrieval behaviours, and more studies are needed from Europe and Australia. © 2018 Health Libraries Group.

The Cervical Cancer gene DataBase (CCDB, http://crdd.osdd.net/raghava/ccdb) is a manually curated catalog of experimentally validated genes that are thought, or are known to be involved in the different stages of cervical carcinogenesis. In spite of the large women population that is presently affected from this malignancy still at present, no database exists that catalogs information on genes associated with cervical cancer. Therefore, we have compiled 537 genes in CCDB that are linked with cervical cancer causation processes such as methylation, gene amplification, mutation, polymorphism and change in expression level, as evident from published literature. Each record contains details related to gene like architecture (exon-intron structure), location, function, sequences (mRNA/CDS/protein), ontology, interacting partners, homology to other eukaryotic genomes, structure and links to other public databases, thus augmenting CCDB with external data. Also, manually curated literature references have been provided to support the inclusion of the gene in the database and establish its association with cervix cancer. In addition, CCDB provides information on microRNA altered in cervical cancer as well as search facility for querying, several browse options and an online tool for sequence similarity search, thereby providing researchers with easy access to the latest information on genes involved in cervix cancer.

The Lariat device has received US Food and Drug Administration (FDA) 510(k) clearance for soft-tissue approximation and is being widely used off-label for left atrial appendage (LAA) exclusion. A comprehensive analysis of safety and effectiveness has not been reported. To perform a systematic review of published literature to assess safety and procedural success, defined as successful closure of the LAA during the index procedure, of the Lariat device. We performed a formal analytic review of the FDA MAUDE (Manufacturer and User Facility Device Experience) database to compile adverse event reports from real-world practice with the Lariat. For the systematic review, PubMed, EMBASE, CINAHL, and the Cochrane Library were searched from January 2007 through August 2014 to identify all studies reporting use of the Lariat device in 3 or more patients. The FDA MAUDE database was queried for adverse events reports related to Lariat use. Data were abstracted in duplicate by 2 physician reviewers. Events from published literature were pooled using a generic inverse variance weighting with a random effects model. Cumulative and individual adverse events were also reported using the FDA MAUDE data set. Procedural adverse events and procedural success. In the systematic review, 5 reports of Lariat device use in 309 participants were identified. Specific complications weighted for inverse of variance of individual studies were urgent need for cardiac surgery (2.3%; 7 of 309 procedures) and death (0.3%; 1 of 309 procedures). Procedural success was 90.3% (279 of 309 procedures). In the FDA MAUDE database, there were 35 unique reports of adverse events with use of the Lariat device. Among these, we identified 5 adverse event reports that noted pericardial effusion and death and an additional 23 reported urgent cardiac surgery without mention of death. This review of published reports and case reports identified risks of adverse events with off-label use of the Lariat device for LAA exclusion. Formal, controlled investigations into the safety and efficacy of the device for this indication are warranted.

Methamphetamine use is a new health concern in Iran, the most populated Persian Gulf country. However, there is no well-documented literature. The current study objectives were to systematically review all published English and Persian studies of the prevalence of methamphetamine use, the general physical and psychiatric-related harms and the availability of methamphetamine treatment and harm reduction services for adult users in Iran. A comprehensive search of the international peer-reviewed and gray literature was undertaken. Multiple electronic and scientific English and Persian databases were systematically searched from January 2002 to September 2014. Additionally, English and Persian gray literature on methamphetamine use was sought using online gray literature databases, library databases and general online searches over the same period of time. Nineteen thousand and two hundred and eight studies, reports and conference papers were identified but only 42 studies were relevant to the study objectives. They were mainly published in 2010-2014. The search results confirmed the seizures of methamphetamine (six studies), the prevalence of methamphetamine use among the general population (three studies), drug users (four studies), women (nine studies) and opiate users in opiate treatment programs (five studies). In addition, methamphetamine use had resulted in blood-borne viral infections (one study), psychosis and intoxication (ten studies). Different reasons had facilitated methamphetamine use. However, the Matrix Model, community therapy and harm reduction services (four studies) had been provided for methamphetamine users in some cities. The current situation of methamphetamine use necessitates more research on the epidemiology and health-related implications. These studies should help in identifying priorities for designing and implementing prevention and educational programs. More active models of engagement with Persian methamphetamine users and the provision of services that meet their specific treatment needs are required. Copyright © 2015 Elsevier B.V.

Objective To determine the accessibility and currency of delirium guidelines, guideline summary papers and evaluation studies, and critically appraise guideline quality. Design Systematic literature search for formal guidelines (in English or French) with focus on delirium assessment and/or management in adults (≥18 years), guideline summary papers and evaluation studies. Full appraisal of delirium guidelines published between 2008 and 2013 and obtaining a ‘Rigour of Development’ domain screening score cut-off of >40% using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Data sources Multiple bibliographic databases, guideline organisation databases, complemented by a grey literature search. Results 3327 database citations and 83 grey literature links were identified. A total of 118 retrieved delirium guidelines and related documents underwent full-text screening. A final 21 delirium guidelines (with 10 being >5 years old), 12 guideline summary papers and 3 evaluation studies were included. For 11 delirium guidelines published between 2008 and 2013, the screening AGREE II ‘Rigour’ scores ranged from 3% to 91%, with seven meeting the cut-off score of >40%. Overall, the highest rating AGREE II domains were ‘Scope and Purpose’ (mean 80.1%, range 64–100%) and ‘Clarity and Presentation’ (mean 76.7%, range 38–97%). The lowest rating domains were ‘Applicability’ (mean 48.7%, range 8–81%) and ‘Editorial Independence’ (mean 53%, range 2–90%). The three highest rating guidelines in the ‘Applicability’ domain incorporated monitoring criteria or audit and costing templates, and/or implementation strategies. Conclusions Delirium guidelines are best sourced by a systematic grey literature search. Delirium guideline quality varied across all six AGREE II domains, demonstrating the importance of using a formal appraisal tool prior to guideline adaptation and implementation into clinical settings. Adding more knowledge translation resources to guidelines may improve their practical application and effective monitoring. More delirium guideline evaluation studies are needed to determine their effect on clinical practice. PMID:28283488

2010-01-01

The role of the patient navigator in cancer care and specifically in breast cancer care has grown to incorporate many titles and functions. To better evaluate the outcomes of patient navigation in breast cancer care, a comprehensive review of empiric literature detailing the efficacy of breast cancer navigation on breast cancer outcomes (screening, diagnosis, treatment, and participation in clinical research) was performed. Published articles were reviewed if published in the scientific literature between January 1990 and April 2009. Searches were conducted using PubMed and Ovid databases. Search terms included MeSH (Medical Subject Headings) terms, "patient navigator," "navigation," "breast cancer," and "adherence." Data-based literature indicates that the role of patient navigation is diverse with multiple roles and targeted populations. Navigation across many aspects of the breast cancer disease trajectory improves adherence to breast cancer care. The empiric review found that navigation interventions have been more commonly applied in breast cancer screening and early diagnosis than for adherence to treatment. There is evidence supporting the role of patient navigation in breast cancer to improve many aspects of breast cancer care. Data describing the role of patient navigation in breast cancer will assist in better defining future direction for the breast navigation role. Ongoing research will better inform issues related to role definition, integration into clinical breast cancer care, impact on quality of life, cost-effectiveness, and sustainability.

This database was constructed to support research in radiation biological dosimetry and risk assessment. Relevant publications were identified through detailed searches of national and international electronic databases and through our personal knowledge of the subject. Publications were numbered and key worded, and referenced in an electronic data-retrieval system that permits quick access through computerized searches on publication number, authors, key words, title, year, and journal name. Photocopies of all publications contained in the database are maintained in a file that is numerically arranged by citation number. This report of the database is provided as a useful reference and overview. Itmore » should be emphasized that the database will grow as new citations are added to it. With that in mind, we arranged this report in order of ascending citation number so that follow-up reports will simply extend this document. The database cite 1212 publications. Publications are from 119 different scientific journals, 27 of these journals are cited at least 5 times. It also contains reference to 42 books and published symposia, and 129 reports. Information relevant to radiation biological dosimetry and risk assessment is widely distributed among the scientific literature, although a few journals clearly dominate. The four journals publishing the largest number of relevant papers are Health Physics, Mutation Research, Radiation Research, and International Journal of Radiation Biology. Publications in Health Physics make up almost 10% of the current database.« less

Compliance of systematic reviews in veterinary journals with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) literature search reporting guidelines.

2017-07-01

Complete, accurate reporting of systematic reviews facilitates assessment of how well reviews have been conducted. The primary objective of this study was to examine compliance of systematic reviews in veterinary journals with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines for literature search reporting and to examine the completeness, bias, and reproducibility of the searches in these reviews from what was reported. The second objective was to examine reporting of the credentials and contributions of those involved in the search process. A sample of systematic reviews or meta-analyses published in veterinary journals between 2011 and 2015 was obtained by searching PubMed. Reporting in the full text of each review was checked against certain PRISMA checklist items. Over one-third of reviews (37%) did not search the CAB Abstracts database, and 9% of reviews searched only 1 database. Over two-thirds of reviews (65%) did not report any search for grey literature or stated that they excluded grey literature. The majority of reviews (95%) did not report a reproducible search strategy. Most reviews had significant deficiencies in reporting the search process that raise questions about how these searches were conducted and ultimately cast serious doubts on the validity and reliability of reviews based on a potentially biased and incomplete body of literature. These deficiencies also highlight the need for veterinary journal editors and publishers to be more rigorous in requiring adherence to PRISMA guidelines and to encourage veterinary researchers to include librarians or information specialists on systematic review teams to improve the quality and reporting of searches.

This paper presents the results of a review of literature relating to knowledge transfer and exchange in healthcare. Treatment, planning and policy decisions in contemporary nursing and healthcare should be based on sound evidence wherever possible, but research knowledge remains generally underused. Knowledge transfer and exchange initiatives aim to facilitate the accessibility, application and production of evidence and may provide solutions to this challenge. This review was conducted to help inform the design and implementation of knowledge transfer and exchange activities for a large healthcare organization. Databases: ASSIA, Business Source Premier, CINAHL, PsychInfo, Medline and the Cochrane Database of Systematic Reviews. An integrative literature review was carried out including an extensive literature search. English language systematic reviews, literature reviews, primary quantitative and qualitative papers and grey literature of high relevance evaluating, describing or discussing knowledge transfer or exchange activities in healthcare were included for review (January 1990-September 2009). Thirty-three papers were reviewed (four systematic reviews, nine literature reviews, one environmental scan, nine empirical studies and ten case studies). Robust research into knowledge transfer and exchange in healthcare is limited. Analysis of a wide range of evidence indicates a number of commonly featured characteristics but further evaluation of these activities would benefit their application in facilitating evidence-based practice in nursing. © 2011 The Authors.

A retrospective review of patients treated at 2 institutions with anterior lumbar interbody fusion using a minimally invasive lateral retroperitoneal approach, and review of literature. To analyze the outcomes from historical literature and from a retrospectively compiled database of patients having undergone anterior interbody fusions performed through a lateral approach. A paucity of published literature exists describing outcomes following lateral approach fusion surgery. Patients treated with extreme lateral interbody fusion (XLIF) were identified through retrospective chart review. Treatment variables included operating room (OR) time, estimated blood loss (EBL), length of hospital stay (LOS), complications, and fusion rate. A literature review, using the National Center for Biotechnology Information databases PubMed/MEDLINE and Google Scholar, yielded 14 peer-reviewed articles reporting outcomes scoring, complications, fusion status, long-term follow-up, and radiographic assessments related to XLIF. Published XLIF results were summarized and evaluated with current study data. A total of 84 XLIF patients were included in the current cohort analysis. OR time, EBL, and length of hospital stay averaged 199 minutes, 155 mL, and 2.6 days, respectively, and perioperative and postoperative complication rates were 2.4% and 6.1%. Mean follow-up was 15.7 months. Sixty-eight patients showed evidence of solid arthrodesis and no subsidence on computed tomography and flexion/extension radiographs. Results were within the ranges of those in the literature. Literature review identified reports of significant improvements in clinical outcomes scores, radiographic measures, and cost effectiveness. Current data corroborates and contributes to the existing body of literature describing XLIF outcomes. Procedures are generally performed with short OR times, minimal EBL, and few complications. Patients recover quickly, requiring minimal hospital stay, although transient hip/thigh pain and/or weakness is common. Long-term outcomes are generally favorable, with maintained improvements in patient-reported pain and function scores as well as radiographic parameters, including high rates of fusion.

to identify how the notion of vulnerability is used in national and international scientific publications that address the problem of tuberculosis. an integrative review of literature published in the databases of the Biblioteca Virtual em Saúde, the United States National Library of Medicine and the Biblioteca Digital Brasileira de Teses e Dissertações, considering the descriptors Tuberculosis and Vulnerability in Portuguese and English. we selected fifty-eight studies published between 1992 and February 2014, which resulted in three categories of analysis. CONCLUSION the link between tuberculosis and the notion of vulnerability has not been sufficiently consolidated in national and international literature. This creates an obstacle for the achievement of the epistemological transformations and pragmatic measures that are required to obtain better results from interventions in the field.

Problems underlying a systematization of spectral data on the methanol molecule are formulated. Data on the energy levels and vacuum wavenumbers acquired from the published literature are presented in the form of information sources imported into the W@DIS information system. Sets of quantum numbers and labels used to describe the CH3OH molecular states are analyzed. The set of labels is different from universally accepted sets. A system of importing the data sources into W@DIS is outlined. The structure of databases characterizing transitions in an isolated CH3OH molecule is introduced and a digital library of the relevant published literature is discussed. A brief description is given of an imported data quality analysis and representation of the results obtained in the form of ontologies for subsequent computer processing.

Elucidation of the mechanistic relationships between drugs, their targets, and diseases is at the core of modern drug discovery research. Thousands of studies relevant to the drug-target-disease (DTD) triangle have been published and annotated in the Medline/PubMed database. Mining this database affords rapid identification of all published studies that confirm connections between vertices of this triangle or enable new inferences of such connections. To this end, we describe the development of Chemotext, a publicly available Web server that mines the entire compendium of published literature in PubMed annotated by Medline Subject Heading (MeSH) terms. The goal of Chemotext is to identify all known DTD relationships and infer missing links between vertices of the DTD triangle. As a proof-of-concept, we show that Chemotext could be instrumental in generating new drug repurposing hypotheses or annotating clinical outcomes pathways for known drugs.

To systematically review and analyze the current status and characteristics of usability studies in China in the field of information technology in general and in the field of healthcare in particular. We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the concept of usability. Six hundred forty-seven publications were selected for analysis. We found that in China the literature on usability in the field of information technology began in 1994 and increased thereafter. The usability definitions from ISO 9241-11:1998 and Nielsen (1993) have been widely recognized and cited. Authors who have published several publications are rare. Fourteen journals have a publishing rate over 1%. Only nine publications about HIT were identified. China's usability research started relatively late. There is a lack of organized research teams and dedicated usability journals. High-impact theoretical studies are scarce. On the application side, no original and systematic research frameworks have been developed. The understanding and definition of usability is not well synchronized with international norms. Besides, usability research in HIT is rare. More human and material resources need to be invested in China's usability research, particularly in HIT.

To conduct an integrative review to evaluate current literature about nonpharmacologic, easily accessible management strategies for pregnancy-related low back and pelvic pain (PR-LBPP). PubMed, CINAHL, Cochrane Database of Systematic Reviews. Original research articles were considered for review if they were full-length publications written in English and published in peer-reviewed journals from 2005 through 2015, included measures of pain and symptoms related to PR-LBPP, and evaluated treatment modalities that used a physical exercise or yoga-based approach for the described conditions. Electronic database searches yielded 1,435 articles. A total of 15 articles met eligibility criteria for further review. These modalities show preliminary promise for pain relief and other related symptoms, including stress and depression. However, our findings also indicate several gaps in knowledge about these therapies for PR-LBPP and methodologic issues with the current literature. Although additional research is required, the results of this integrative review suggest that clinicians may consider recommending nonpharmacologic treatment options, such as gentle physical activity and yoga-based interventions, for PR-LBPP and related symptoms.

2009-01-01

Long-term accumulation of salts in wetlands at Bowdoin National Wildlife Refuge (NWR), Mont., has raised concern among wetland managers that increasing salinity may threaten plant and invertebrate communities that provide important habitat and food resources for migratory waterfowl. Currently, the U.S. Fish and Wildlife Service (USFWS) is evaluating various water management strategies to help maintain suitable ranges of salinity to sustain plant and invertebrate resources of importance to wildlife. To support this evaluation, the USFWS requested that the U.S. Geological Survey (USGS) provide information on salinity ranges of water and soil for common plants and invertebrates on Bowdoin NWR lands. To address this need, we conducted a search of the literature on occurrences of plants and invertebrates in relation to salinity and pH of the water and soil. The compiled literature was used to (1) provide a general overview of salinity concepts, (2) document published tolerances and adaptations of biota to salinity, (3) develop databases that the USFWS can use to summarize the range of reported salinity values associated with plant and invertebrate taxa, and (4) perform database summaries that describe reported salinity ranges associated with plants and invertebrates at Bowdoin NWR. The purpose of this report is to synthesize information to facilitate a better understanding of the ecological relations between salinity and flora and fauna when developing wetland management strategies. A primary focus of this report is to provide information to help evaluate and address salinity issues at Bowdoin NWR; however, the accompanying databases, as well as concepts and information discussed, are applicable to other areas or refuges. The accompanying databases include salinity values reported for 411 plant taxa and 330 invertebrate taxa. The databases are available in Microsoft Excel version 2007 (http://pubs.usgs.gov/sir/2009/5098/downloads/databases_21april2009.xls) and contain 27 data fields that include variables such as taxonomic identification, values for salinity and pH, wetland classification, location of study, and source of data. The databases are not exhaustive of the literature and are biased toward wetland habitats located in the glaciated North-Central United States; however, the databases do encompass a diversity of biota commonly found in brackish and freshwater inland wetland habitats.

Molecular recognition between biological macromolecules and organic small molecules plays an important role in various life processes. Both structural information and binding data of biomolecular complexes are indispensable for depicting the underlying mechanism in such an event. The PDBbind database was created to collect experimentally measured binding data for the biomolecular complexes throughout the Protein Data Bank (PDB). It thus provides the linkage between structural information and energetic properties of biomolecular complexes, which is especially desirable for computational studies or statistical analyses. Since its first public release in 2004, the PDBbind database has been updated on an annual basis. The latest release (version 2013) provides experimental binding affinity data for 10,776 biomolecular complexes in PDB, including 8302 protein-ligand complexes and 2474 other types of complexes. In this article, we will describe the current methods used for compiling PDBbind and the updated status of this database. We will also review some typical applications of PDBbind published in the scientific literature. All contents of this database are freely accessible at the PDBbind-CN Web server at http://www.pdbbind-cn.org/. wangrx@mail.sioc.ac.cn.

Masko, Elizabeth M; Allott, Emma H; Freedland, Stephen J

2013-05-01

Prostate cancer (PCa) remains one of the most diagnosed malignancies in the world, correlating with regions where men consume more of a so-called Western-style diet. As such, there is much interest in understanding the role of lifestyle and diet on the incidence and progression of PCa. To provide a summary of published literature with regard to dietary macro- and micronutrients and PCa incidence and progression. A literature search was completed using the PubMed database for all studies published on diet and PCa in June 2012 or earlier. Primary literature and meta-analyses were given preference over other review articles when possible. The literature was reviewed on seven dietary components: carbohydrates, protein, fat and cholesterol, vegetables, vitamins and minerals, and phytochemicals. Current literature linking these nutrients to PCa is limited at best, but trends in the published data suggest consumption of carbohydrates, saturated and ω-6 fats, and certain vitamin supplements may promote PCa risk and progression. Conversely, consumption of many plant phytochemicals and ω-3 fatty acids seem to slow the risk and progression of the disease. All other nutrients seem to have no effect or data are inconclusive. A brief summary about the clinical implications of dietary interventions with respect to PCa prevention, treatment, and survivorship is provided. Due to the number and heterogeneity of published studies investigating diet and PCa, it is difficult to determine what nutrients make up the perfect diet for the primary and secondary prevention of PCa. Because diets are made of multiple macro- and micronutrients, further prospective studies are warranted, particularly those investigating the relationship between whole foods instead of a single nutritional component.

Occipital neuralgia (ON) is a disorder characterized by sharp, electrical, paroxysmal pain, originating from the occiput and extending along the posterior scalp, in the distribution of the greater, lesser, and/or third occipital nerve. Occipital nerve stimulation (ONS) constitutes a promising therapy for medically refractory ON because it is reversible with minimal side effects and has shown continued efficacy with long-term follow-up. To conduct a systematic literature review and provide treatment recommendations for the use of ONS for the treatment of patients with medically refractory ON. A systematic literature search was conducted using the PubMed database and the Cochrane Library to locate articles published between 1966 and April 2014 using MeSH headings and keywords relevant to ONS as a means to treat ON. A second literature search was conducted using the PubMed database and the Cochrane Library to locate articles published between 1966 and June 2014 using MeSH headings and keywords relevant to interventions that predict response to ONS in ON. The strength of evidence of each article that underwent full text review and the resulting strength of recommendation were graded according to the guidelines development methodology of the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Guidelines Committee. Nine studies met the criteria for inclusion in this guideline. All articles provided Class III Level evidence. Based on the data derived from this systematic literature review, the following Level III recommendation can be made: the use of ONS is a treatment option for patients with medically refractory ON.

Introduction E-cigarettes or electronic nicotine delivery systems (ENDS) have recently attracted considerable attention. Among some individuals there is strong debate and a polarisation of views about the public health benefits versus harms of ENDS. With little regulation, the ENDS market is evolving, and new products are introduced and marketed constantly. Rapid developments in manufacturing, marketing and consumer domains related to ENDS will warrant frequent re-evaluation, based on the state of the evolving science. The purpose of this article is to describe a protocol for an ongoing comprehensive review of the published scientific literature on ENDS. Methods and analysis We will undertake a systematic review of published empirical research literature on ENDS using the National Library of Medicine's PubMed electronic database to search for relevant articles. Data from included studies will be extracted into a standardised form, tables with study details and key outcomes for each article will be created, and studies will be synthesised qualitatively. Ethics and dissemination This review synthesises published literature and presents no primary data. Therefore, no ethical approval is required for this study. Subsequent papers will provide greater detail on results, within select categories, that represent gaps in the literature base. PMID:25926149

Othering: difference understood??: a 10-year analysis and critique of the nursing literature.

PubMed

Canales, Mary K

2010-01-01

It has been 10 years since Advances in Nursing Science (ANS) published the first article that articulated othering within a nursing framework. This issue's topic, Critique and Replication, provided an opportunity for analysis of the influence of the original ANS article on the visibility and application of othering within nursing literature. Comprehensive searches of major health databases identified 32 publications citing the original ANS article. The analysis focused on exclusionary and inclusionary othering, role taking, and constructions of the other. Results indicate that although othering has become more visible within nursing literature, exclusionary othering dominates. The article concludes with thoughts for moving beyond othering and toward engagement.

Orthorexia Nervosa: A Review of the Literature.

Costa, Christine B; Hardan-Khalil, Kholoud; Gibbs, Kimberly

2017-12-01

The phenomenon of orthorexia nervosa (ON) has been noted by clinicians since 1996 and described in the scientific literature, and yet there is no formal recognition of ON as a psychiatric diagnosis. Review the latest available literature regarding diagnoses similarities, presentation uniqueness, assessment/assessment tools, and suggested treatments of ON. A literature search of four databases focusing on articles published between 2000 and 2016 was conducted to evaluate the status of the literature on Orthorexia. Among the 15 articles selected for this review, similarities with other psychiatric disorders emerged, confusion about use of assessment tools existed, and the lack of evidence based treatments for ON was pronounced. More research is needed to determine the prevalence of pathologically unhealthy, obsessive, "self-defined healthy," eating behaviors, and to determine if ON is a unique eating disorder or just a subset of another disorder.

Summary Background: Plantar fasciitis (PF) is reported in different sports mainly in running and soccer athletes. Purpose of this study is to conduct a systematic review of published literature concerning the diagnosis and treatment of PF in both recreational and élite athletes. The review was conducted and reported in accordance with the PRISMA statement. Methods: The following electronic databases were searched: PubMed, Cochrane Library and Scopus. As far as PF diagnosis, we investigated the electronic databases from January 2006 to June 2016, whereas in considering treatments all data in literature were investigated. Results: For both diagnosis and treatment, 17 studies matched inclusion criteria. The results have highlighted that the most frequently used diagnostic techniques were Ultrasonography and Magnetic Resonance Imaging. Conventional, complementary, and alternative treatment approaches were assessed. Conclusions: In reviewing literature, we were unable to find any specific diagnostic algorithm for PF in athletes, due to the fact that no different diagnostic strategies were used for athletes and non-athletes. As for treatment, a few literature data are available and it makes difficult to suggest practice guidelines. Specific studies are necessary to define the best treatment algorithm for both recreational and élite athletes. Level of evidence: Ib. PMID:28717618

Is grey literature essential for a better control of publication bias in psychiatry? An example from three meta-analyses of schizophrenia.

Systematic reviews in mental health have become useful tools for health professionals in view of the massive amount and heterogeneous nature of biomedical information available today. In order to determine the risk of bias in the studies evaluated and to avoid bias in generalizing conclusions from the reviews it is therefore important to use a very strict methodology in systematic reviews. One bias which may affect the generalization of results is publication bias, which is determined by the nature and direction of the study results. To control or minimize this type of bias, the authors of systematic reviews undertake comprehensive searches of medical databases and expand on the findings, often undertaking searches of grey literature (material which is not formally published). This paper attempts to show the consequences (and risk) of generalizing the implications of grey literature in the control of publication bias, as was proposed in a recent systematic work. By repeating the analyses for the same outcome from three different systematic reviews that included both published and grey literature our results showed that confusion between grey literature and publication bias may affect the results of a concrete meta-analysis.

For 28 years, the Intergovernmental Panel on Climate Change (IPCC) has been assessing the potential risks associated with anthropogenic climate change. Although interest in climate change and health is growing, the implications arising from their interaction remain understudied. Generating a greater understanding of the health impacts of climate change could be key step in inciting some of the changes necessary to decelerate global warming. A long-term and broad overview of the existing scientific literature in the field of climate change and health is currently missing in order to ensure that all priority areas are being adequately addressed. In this paper we outline our methods to conduct a scoping review of the published peer-reviewed literature on climate change and health between 1990 and 2015. A detailed search strategy will be used to search the PubMed and Web of Science databases. Specific inclusion and exclusion criteria will be applied in order to capture the most relevant literature in the time frame chosen. Data will be extracted, categorised and coded to allow for statistical analysis of the results. No ethical approval was required for this study. A searchable database of climate change and health publications will be developed and a manuscript will be complied for publication and dissemination of the findings. We anticipate that this study will allow us to map the trends observed in publications over the 25-year time period in climate change and health research. It will also identify the research areas with the highest volume of publications as well as highlight the research trends in climate change and health. Published by the BMJ Publishing Group Limited.

Roine, R; Ohinmaa, A; Hailey, D

2001-09-18

To clarify the current status of telemedicine, we carried out a systematic review of the literature. We identified controlled assessment studies of telemedicine that reported patient outcomes, administrative changes or economic assessments and assessed the quality of that literature. We carried out a systematic electronic search for articles published from 1966 to early 2000 using the MEDLINE (1966-April 2000), HEALTHSTAR (1975-January 2000), EMBASE (1988-February 2000) and CINALH (1982-January 2000) databases. In addition, the HSTAT database (Health Services/Technology Assessment Text, US National Library of Medicine), the Database of Abstracts of Reviews of Effectiveness (DARE, NHS Centre for Reviews and Dissemination, United Kingdom), the NHS Economic Evaluation Database and the Cochrane Controlled Trials Register were searched. We consulted experts in the field and did a manual search of the reference lists of review articles. A total of 1124 studies were identified. Based on a review of the abstracts, 133 full-text articles were obtained for closer inspection. Of these, 50 were deemed to represent assessment studies fulfilling the inclusion criteria of the review. Thirty-four of the articles assessed at least some clinical outcomes; the remaining 16 were mainly economic analyses. Most of the available literature referred only to pilot projects and short-term outcomes, and most of the studies were of low quality. Relatively convincing evidence of effectiveness was found only for teleradiology, teleneurosurgery, telepsychiatry, transmission of echocardiographic images, and the use of electronic referrals enabling e-mail consultations and video conferencing between primary and secondary health care providers. Economic analyses suggested that teleradiology, especially transmission of CT images, can be cost-saving. Evidence regarding the effectiveness or cost-effectiveness of telemedicine is still limited. Based on current scientific evidence, only a few telemedicine applications can be recommended for broader use.

AIM To better understand how pediatric floating knee injuries are managed after the wide spread use of new orthopaedic technology. METHODS We searched EMBASE, COCHRANE and MEDLINE computerized literature databases from the earliest date available in the databases to February 2017 using the following search term including variants and pleural counterparts: Pediatric floating knee. All studies were thoroughly reviewed by multiple authors. Reference lists from all articles were scrutinized to identify any additional studies of interest. A final database of individual patients was assembled from the literature. Univariate and multivariate statistical tests were applied to the assembled database to assess differences in outcomes. RESULTS The English language literature contains series with a total of 97 pediatric patients who sustained floating knee injuries. Patients averaged 9.3 years of age and were mostly male (73). Approximately 25% of the fractures were open injuries, more tibia (27) than femur (10). Over 75% of the fractures of both the tibia and the femur involved the diaphysis. More than half (52) of the patients were treated non-operatively for both fractures. As a sequela of the injury 32 (33%) patients were left with a limb length discrepancy, 24 (25%) patients had lengthening of the injured limb at follow up, while 8 (8%) had shortening of the affected limb. Infection developed in 9 patients and 3 had premature physeal closure. Younger patients were more likely to be treated non-operatively (P < 0.001) and patients treated with operative intervention had statistically significant shorter hospital length of stays (P = 0.001). CONCLUSION Given the predominance of non-operative management in published studies, the available literature is not clinically relevant since the popularization of internal fixation for pediatric long-bone fractures PMID:28875130

Purpose To assess those published cases of yellow fever (YF) vaccine-associated viscerotropic disease that meet the Brighton Collaboration criteria and to assess the safety of YF vaccine with respect to viscerotropic disease. Literature search Ten electronic databases were searched with no restriction of date or language and reference lists of retrieved articles. Methods All abstracts and titles were independently read by two reviewers and data independently entered by two reviewers. Results All serious adverse events that met the Brighton Classification criteria were associated with first YF vaccinations. Sixty-two published cases (35 died) met the Brighton Collaboration viscerotropic criteria, with 32 from the US, six from Brazil, five from Peru, three from Spain, two from the People’s Republic of China, one each from Argentina, Australia, Belgium, Ecuador, France, Germany, Ireland, New Zealand, Portugal, and the UK, and four with no country stated. Two cases met both the viscerotropic and YF vaccine-associated neurologic disease criteria. Seventy cases proposed by authors as viscerotropic disease did not meet any Brighton Collaboration viscerotropic level of diagnostic certainty or any YF vaccine-associated viscerotropic disease causality criteria (37 died). Conclusion Viscerotropic disease is rare in the published literature and in pharmacovigilance databases. All published cases were from developing countries. Because the symptoms are usually very severe and life threatening, it is unlikely that cases would not come to medical attention (but might not be published). Because viscerotropic disease has a highly predictable pathologic course, it is likely that viscerotropic disease post-YF vaccine occurs in low-income countries with the same incidence as in developing countries. YF vaccine is a very safe vaccine that likely confers lifelong immunity. PMID:27784992

To systematically review economic evaluations in gastroenterology, relating to Brazil, published between 1980 and 2013. We selected full and partial economic evaluations from among those retrieved by searching the following databases: MEDLINE (PubMed); Excerpta Medica; the Latin American and Caribbean Health Sciences Literature database; the Scientific Electronic Library Online; the database of the Centre for Reviews and Dissemination; the National Health Service (NHS) Economic Evaluation Database; the NHS Health Technology Assessment database; the Health Economics database of the Brazilian Virtual Library of Health; Scopus; Web of Science; and the Brazilian Network for the Evaluation of Health Technologies. Two researchers, working independently, selected the studies and extracted the data. We identified 535 health economic evaluations relating to Brazil and published in the 1980-2013 period. Of those 535 articles, only 40 dealt with gastroenterology. Full and partial economic evaluations respectively accounted for 23 (57.5%) and 17 (42.5%) of the 40 studies included. Among the 23 full economic evaluations, there were 11 cost-utility analyses, seven cost-effectiveness analyses, four cost-consequence analyses, and one cost-minimization analysis. Of the 40 studies, 25 (62.5%) evaluated medications; 7 (17.5%) evaluated procedures; and 3 (7.5%) evaluated equipment. Most (55%) of the studies were related to viral hepatitis, and most (63.4%) were published after 2010. Other topics included gastrointestinal cancer, liver transplantation, digestive diseases and hernias. Over the 33-year period examined, the number of such economic evaluations relating to Brazil, especially of those evaluating medications for the treatment of hepatitis, increased considerably. Further studies are needed in order to ensure that expenditures on health care in Brazil are made as fairly and efficiently as possible.

In plants, various phloem-mobile macromolecules including noncoding RNAs, mRNAs and proteins are suggested to act as important long-distance signals in regulating crucial physiological and morphological transition processes such as flowering, plant growth and stress responses. Given recent advances in high-throughput sequencing technologies, numerous mobile macromolecules have been identified in diverse plant species from different plant families. However, most of the identified mobile macromolecules are not annotated in current versions of species-specific databases and are only available as non-searchable datasheets. To facilitate study of the mobile signaling macromolecules, we compiled the PlaMoM (Plant Mobile Macromolecules) database, a resource that provides convenient and interactive search tools allowing users to retrieve, to analyze and also to predict mobile RNAs/proteins. Each entry in the PlaMoM contains detailed information such as nucleotide/amino acid sequences, ortholog partners, related experiments, gene functions and literature. For the model plant Arabidopsis thaliana, protein-protein interactions of mobile transcripts are presented as interactive molecular networks. Furthermore, PlaMoM provides a built-in tool to identify potential RNA mobility signals such as tRNA-like structures. The current version of PlaMoM compiles a total of 17 991 mobile macromolecules from 14 plant species/ecotypes from published data and literature. PlaMoM is available at http://www.systembioinfo.org/plamom/. © The Author(s) 2016. Published by Oxford University Press on behalf of Nucleic Acids Research.

Insurance claims data: a possible solution for a national sports injury surveillance system? An evaluation of data information against ASIDD and consensus statements on sports injury surveillance.

2014-06-12

Before preventive actions can be suggested for sports injuries at the national level, a solid surveillance system is required in order to study their epidemiology, risk factors and mechanisms. There are guidelines for sports injury data collection and classifications in the literature for that purpose. In Sweden, 90% of all athletes (57/70 sports federations) are insured with the same insurance company and data from their database could be a foundation for studies on acute sports injuries at the national level. To evaluate the usefulness of sports injury insurance claims data in sports injury surveillance at the national level. A database with 27 947 injuries was exported to an Excel file. Access to the corresponding text files was also obtained. Data were reviewed on available information, missing information and dropouts. Comparison with ASIDD (Australian Sports Injury Data Dictionary) and existing consensus statements in the literature (football (soccer), rugby union, tennis, cricket and thoroughbred horse racing) was performed in a structured manner. Comparison with ASIDD showed that 93% of the suggested data items were present in the database to at least some extent. Compliance with the consensus statements was generally high (13/18). Almost all claims (83%) contained text information concerning the injury. Relatively high-quality sports injury data can be obtained from a specific insurance company at the national level in Sweden. The database has the potential to be a solid base for research on acute sports injuries in different sports at the national level. Published by the BMJ Publishing Group Limited.

Objective: To quantitatively analyze the current status and development trends regarding the land use regression (LUR) models on ambient air pollution studies. Methods: Relevant literature from the PubMed database before June 30, 2017 was analyzed, using the Bibliographic Items Co-occurrence Matrix Builder (BICOMB 2.0). Keywords co-occurrence networks, cluster mapping and timeline mapping were generated, using the CiteSpace 5.1.R5 software. Relevant literature identified in three Chinese databases was also reviewed. Results: Four hundred sixty four relevant papers were retrieved from the PubMed database. The number of papers published showed an annual increase, in line with the growing trend of the index. Most papers were published in the journal of Environmental Health Perspectives . Results from the Co-word cluster analysis identified five clusters: cluster#0 consisted of birth cohort studies related to the health effects of prenatal exposure to air pollution; cluster#1 referred to land use regression modeling and exposure assessment; cluster#2 was related to the epidemiology on traffic exposure; cluster#3 dealt with the exposure to ultrafine particles and related health effects; cluster#4 described the exposure to black carbon and related health effects. Data from Timeline mapping indicated that cluster#0 and#1 were the main research areas while cluster#3 and#4 were the up-coming hot areas of research. Ninety four relevant papers were retrieved from the Chinese databases with most of them related to studies on modeling. Conclusion: In order to better assess the health-related risks of ambient air pollution, and to best inform preventative public health intervention policies, application of LUR models to environmental epidemiology studies in China should be encouraged.

The Carcinogenic Potency Database (CPDB) is a systematic and unifying resource that standardizes the results of chronic, long-term animal cancer tests which have been conducted since the 1950s. The analyses include sufficient information on each experiment to permit research into many areas of carcinogenesis. Both qualitative and quantitative information is reported on positive and negative experiments that meet a set of inclusion criteria. A measure of carcinogenic potency, TD50 (daily dose rate in mg/kg body weight/day to induce tumors in half of test animals that would have remained tumor-free at zero dose), is estimated for each tissue-tumor combination reported. Thismore » article is the ninth publication of a chronological plot of the CPDB; it presents results on 560 experiments of 188 chemicals in mice, rats, and hamsters from 185 publications in the general literature updated through 1997, and from 15 Reports of the National Toxicology Program in 1997-1998.

Aminde, Leopold Ndemnge; Veerman, Lennert

2016-12-21

Low-income and middle-income countries (LMICs) are experiencing a growing disease burden due to cardiovascular and other chronic non-communicable diseases. Interventions for the control of these diseases are paramount; however, these countries are faced with competing health and financial needs. There is an urgent need for quality evidence on cost-effective strategies to address these chronic diseases. We aim to synthesise the current literature on economic evaluations of interventions for primary and secondary cardiovascular disease prevention in LMICs. A systematic review of studies (published and unpublished) in LMICs up to 30 October 2016 will be conducted. The following databases will be searched: PubMed/MEDLINE, EMBASE, SCOPUS, CINAHL, Web of Science, EconLit, NHS Economic Evaluations Database (NHS EED). Data sources specific to African literature, such as the WHO AFROLIB, Africa Index Medicus and African Journals online (AJOL) as well as grey literature, will also be searched. 2 reviewers shall independently screen potential articles for inclusion and disagreements shall be resolved by consensus. Quality appraisal of studies shall be done using Drummond's checklist for economic evaluation of studies. A descriptive synthesis of the evidence obtained is planned. The primary outcomes will be costs per life years gained or unit of clinical outcome, cost per quality-adjusted life years or disability-adjusted life years. This systematic review protocol has been prepared according to the Preferred Reporting Items for Systematic reviews and Meta-analyses for Protocols (PRISMA-P) 2015 statement. Ethics approval is not required considering that this is a protocol for a systematic review of published studies. Results from this review will be disseminated via conference presentations and peer-reviewed journal publications. CRD42016043510. Published by the BMJ Publishing Group Limited.

Background Risk of cancer is determined by a complex interplay of genetic and environmental factors. Although the study of gene-environment (GxE) interactions has been an active area of research, little is reported about the known findings in the literature. Methods To examine the state of the science in GxE research in cancer, we performed a systematic review of published literature using gene-environment or pharmacogenomic flags from two curated databases of genetic association studies, the Human Genome Epidemiology (HuGE) literature finder and Cancer Genome-Wide Association and Meta Analyses Database (CancerGAMAdb), from January 1, 2001, to January 31, 2011. A supplemental search using HuGE was conducted for articles published February 1, 2011, to April 11, 2013. A 25% sample of the supplemental publications was reviewed. Results A total of 3,019 articles were identified in the original search. From these articles, 243 articles were determined to be relevant based on inclusion criteria (more than 3,500 interactions). From the supplemental search (1,400 articles identified), 29 additional relevant articles (1,370 interactions) were included. The majority of publications in both searches examined GxE in colon, rectal, or colorectal cancer types; breast; or lung cancer. Specific interactions examined most frequently included environmental factors categorized as energy balance (e.g., body mass index (BMI), diet), exogenous (e.g., oral contraceptives) and endogenous hormones (e.g., menopausal status), chemical environment (e.g., grilled meats), and lifestyle (e.g., smoking, alcohol intake). In both searches, the majority of interactions examined were using loci from candidate genes studies and none of the studies were genome-wide interaction studies (GEWIS). The most commonly reported measure was the interaction p-value, of which a sizable number of p-values were considered statistically significant (i.e., < 0.05). In addition, the magnitudes of interactions reported were modest. Conclusion Observations of published literature suggest that opportunity exists for increased sample size in GxE research, including GWAS identified loci in GxE studies, exploring more GWAS approaches in GxE such as GEWIS, and improving the reporting of GxE findings.

Sanders, Kathleen; Moran, Zelda; Shi, Zaixing; Paul, Rachel; Greenlee, Heather

2016-08-01

To present a clinical update of natural products for cancer prevention and provide oncology nurses with an evidence-based review of natural products for patient counseling and education. Clinical trials published in PubMed. In the past 4 years since the publication of the original review there have been minimal changes in the conclusions of the published literature on the use of natural products for cancer prevention. To date, clinical trials have not demonstrated conclusive benefit of using natural products for cancer prevention, and current guidelines do not recommend their use. This review provides an update on published and ongoing trials and can serve as an updated resource for nurses. Evidence-based natural products databases can help nurses stay current with the scientific literature and be effective educators and health coaches for their patients, who can be influenced by marketing of unregulated products. Patients often discuss the use of natural products with nurses. Nurses have an opportunity to educate and coach patients in effective preventive lifestyle practices. Copyright © 2016 Elsevier Inc.

An Investigation of Teaching and Learning Programs in Pharmacy Education

PubMed Central

Baia, Patricia

2016-01-01

Objective. To investigate published, peer-reviewed literature on pharmacy teaching and learning development programs and to synthesize existing data, examine reported efficacy and identify future areas for research. Methods. Medline and ERIC databases were searched for studies on teaching development programs published between 2001 and 2015. Results. Nineteen publications were included, representing 21 programs. Twenty programs were resident teaching programs, one program described faculty development. The majority of programs spanned one year and delivered instruction on teaching methodologies and assessment measures. All except one program included experiential components. Thirteen publications presented outcomes data; most measured satisfaction and self-perceived improvement. Conclusion. Published literature on teacher development in pharmacy is focused more on training residents than on developing faculty members. Although programs are considered important and highly valued by program directors and participants, little data substantiates that these programs improve teaching. Future research could focus on measurement of program outcomes and documentation of teaching development for existing faculty members. PMID:27293226

Characterizing the quantity, lithology, age, and properties of rocks and sediments in the upper crust is central to many questions in Earth science. Although a large number of geological maps, regional syntheses, and sample-based measurements have been published in a variety of formats, there is no system for integrating and accessing rock record-derived data or for facilitating the large-scale quantitative interrogation of the physical, chemical, and biological properties of Earth's crust. Here we describe two data resources that aim to overcome some of these limitations: 1) Macrostrat, a geospatial database and supporting cyberinfrastructure that is designed to enable quantitative analyses of the entire assemblage of surface and subsurface sedimentary, igneous and metamorphic rocks, and 2) GeoDeepDive, a digital library and high throughput computing system designed to facilitate the location and extraction of information and data from the published literature. Macrostrat currently contains general summaries of the age and lithology of rocks and sediments in the upper crust at 1,474 regions in North and Central America, the Caribbean, New Zealand, and the deep sea. Distributed among these geographic regions are nearly 34,000 lithologically and chronologically-defined geological units, many of which are linked to a bedrock geologic map database with more than 1.7 million globally distributed units. Sample-derived data, including fossil occurrences in the Paleobiology Database and more than 180,000 geochemical and outcrop-derived measurements are linked to Macrostrat units and/or lithologies within those units. The rock names, lithological terms, and geological time intervals that are applied to Macrostrat units define a hierarchical, spatially and temporally indexed vocabulary that is leveraged by GeoDeepDive in order to provide researchers access to data within the scientific literature as it is published and ingested into the infrastructure. All data in Macrostrat are accessible via an Application Programming Interface, which enables the development of mobile and analytical applications. The GeoDeepDive infrastructure also supports the development and execution of applications that are tailored to the specific, literature-based data location and extraction needs of geoscientists.

Mapping the literature of nursing: 1996–2000

2006-01-01

Introduction: This project is a collaborative effort of the Task Force on Mapping the Nursing Literature of the Nursing and Allied Health Resources Section of the Medical Library Association. This overview summarizes eighteen studies covering general nursing and sixteen specialties. Method: Following a common protocol, citations from source journals were analyzed for a three-year period within the years 1996 to 2000. Analysis included cited formats, age, and ranking of the frequency of cited journal titles. Highly cited journals were analyzed for coverage in twelve health sciences and academic databases. Results: Journals were the most frequently cited format, followed by books. More than 60% of the cited resources were published in the previous seven years. Bradford's law was validated, with a small core of cited journals accounting for a third of the citations. Medical and science databases provided the most comprehensive access for biomedical titles, while CINAHL and PubMed provided the best access for nursing journals. Discussion: Beyond a heavily cited core, nursing journal citations are widely dispersed among a variety of sources and disciplines, with corresponding access via a variety of bibliographic tools. Results underscore the interdisciplinary nature of the nursing profession. Conclusion: For comprehensive searches, nurses need to search multiple databases. Libraries need to provide access to databases beyond PubMed, including CINAHL and academic databases. Database vendors should improve their coverage of nursing, biomedical, and psychosocial titles identified in these studies. Additional research is needed to update these studies and analyze nursing specialties not covered. PMID:16636714

High-density microarray technology permits the quantitative and simultaneous monitoring of thousands of genes. The interpretation challenge is to extract relevant information from this large amount of data. A growing variety of statistical analysis approaches are available to identify clusters of genes that share common expression characteristics, but provide no information regarding the biological similarities of genes within clusters. The published literature provides a potential source of information to assist in interpretation of clustering results. We describe a data mining method that uses indexing terms ('keywords') from the published literature linked to specific genes to present a view of the conceptual similarity of genes within a cluster or group of interest. The method takes advantage of the hierarchical nature of Medical Subject Headings used to index citations in the MEDLINE database, and the registry numbers applied to enzymes.

Huckabee, Maggie-Lee; Doeltgen, Sebastian

2007-10-12

The aim of this review article is to advise the New Zealand medical community about the application of neuromuscular electrical stimulation (NMES) as a treatment for pharyngeal swallowing impairment (dysphagia). NMES in this field of rehabilitation medicine has quickly emerged as a widely used method overseas but has been accompanied by significant controversy. Basic information is provided about the physiologic background of electrical stimulation. The literature reviewed in this manuscript was derived through a computer-assisted search using the biomedical database Medline to identify all relevant articles published until from the initiation of the databases up to January 2007. The reviewers used the following search strategy: [(deglutition disorders OR dysphagia) AND (neuromuscular electrical stimulation OR NMES)]. In addition, the technique of reference tracing was used and very recently published studies known to the authors but not yet included in the database systems were included. This review elucidates not only the substantive potential benefit of this treatment, but also potential key concerns for patient safety and long term outcome. The discussion within the clinical and research communities, especially around the commercially available VitalStim stimulator, is objectively explained.

A scoping review of 10 years of published literature on community-based rehabilitation.

Cleaver, Shaun; Nixon, Stephanie

2014-01-01

To identify the characteristics of peer-reviewed literature on community-based rehabilitation (CBR) in low- and middle-income countries published in English from 2003 to 2012. This scoping review involved a systematic search of electronic databases using specific keyword/subject heading combinations. Journal articles were included if they were published in English, used "CBR" as related to rehabilitation with persons with disabilities and not limited to high-income countries (HICs). Data were charted according to both pre-determined and emergent categories. A subset of articles was charted by two reviewers to ensure reliability of variables. A total of 114 articles were included. Fifty-two articles presented empirical research and 49 were published in one of two journals. The articles represented CBR activity in 26 specific countries, although only two of these were in Europe and only one was in the Americas. Authors were predominantly affiliated at universities and in HICs. This scoping review identified and characterized a large pool of literature on CBR, facilitating its incorporation into research and practice. Future research should examine the engagement of persons with disabilities in creating CBR literature, and analysis of literature in languages other than English. Implications for Rehabilitation Community-based rehabilitation (CBR) has been promoted as a rehabilitation strategy of choice in low- and middle-income countries (LMICs), but it has been critiqued for lack of an evidence base. A large number (114) of peer-reviewed articles were published on CBR between 2003 and 2012. Just under half of these articles (45%) presented empirical research, indicating that the evidence base for CBR is growing but will benefit from continued, rigorous inquiry. Furthermore, researchers from LMICs appear to be largely under-represented in published CBR research, flagging the need to support LMIC partners to share their CBR research in peer-reviewed journals.

Towards the ophthalmology patentome: a comprehensive patent database of ocular drugs and biomarkers.

Mucke, Hermann A M; Mucke, Eva; Mucke, Peter M

2013-01-01

We are currently building a database of all patent documents that contain substantial information related to pharmacology, drug delivery, tissue technology, and molecular diagnostics in ophthalmology. The goal is to establish a 'patentome', a body of cleaned and annotated data where all text-based, chemistry and pharmacology information can be accessed and mined in its context. We provide metrics on patent convention treaty documents, which demonstrate that ocular-related patenting has shown stronger growth than general patent cooperation treaty patenting during the past 25 years, and, while the majority of applications of this type have always provided substantial biological data, both data support and objections by patent examiners have been increasing since 2006-2007. Separately, we present a case study of chemistry information extraction from patents published during the 1950s and 1970s, which reveal compounds with corneal anesthesia potential that were never published in the peer-reviewed literature.

Nanotechnology and its Application in Dentistry

Nanotechnology influences almost every facet of everyday life from security to medicine. The concept of nanotechnology is that when one goes down to the bottom of things, one can discover unlimited possibilities and potential of the basic particle. In nanotechnology, analysis can be made to the level of manipulating atoms, molecules and chemical bonds between them. The growing interest in the dental applications of nanotechnology is leading to the emergence of a new field called nanodentistry. An electronic database search that included PubMed, MedLine, and Cochrane library was conducted. Key words used in the search are nanotechnology dentistry and applications. Language limitation was set as articles reviewed were only those written and published in English language. We did not search the gray literature. Initially, 52 articles were retrieved from the database, and articles considered were those published from 2008 to 2013. Eight articles that met the selection criteria were eventually selected and reviewed. PMID:25364585

The rate of growth in scientific publication and the decline in coverage provided by Science Citation Index.

PubMed

Larsen, Peder Olesen; von Ins, Markus

2010-09-01

The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

In silico drug discovery has been proved to be a solidly established key component in early drug discovery. However, this task is hampered by the limitation of quantity and quality of compound databases for screening. In order to overcome these obstacles, freely accessible database resources of compounds have bloomed in recent years. Nevertheless, how to choose appropriate tools to treat these freely accessible databases are crucial. To the best of our knowledge, this is the first systematic review on this issue. The existed advantages and drawbacks of chemical databases were analyzed and summarized based on the collected six categories of freely accessible chemical databases from literature in this review. Suggestions on how and in which conditions the usage of these databases could be reasonable were provided. Tools and procedures for building 3D structure chemical libraries were also introduced. In this review, we described the freely accessible chemical database resources for in silico drug discovery. In particular, the chemical information for building chemical database appears as attractive resources for drug design to alleviate experimental pressure.

Our group developed two biological applications, Biblio-MetReS and Homol-MetReS, accessing the same database of organisms with annotated genes. Biblio-MetReS is a data-mining application that facilitates the reconstruction of molecular networks based on automated text-mining analysis of published scientific literature. Homol-MetReS allows functional (re)annotation of proteomes, to properly identify both the individual proteins involved in the process(es) of interest and their function. It also enables the sets of proteins involved in the process(es) in different organisms to be compared directly. The efficiency of these biological applications is directly related to the design of the shared database. We classified and analyzed the different kinds of access to the database. Based on this study, we tried to adjust and tune the configurable parameters of the database server to reach the best performance of the communication data link to/from the database system. Different database technologies were analyzed. We started the study with a public relational SQL database, MySQL. Then, the same database was implemented by a MapReduce-based database named HBase. The results indicated that the standard configuration of MySQL gives an acceptable performance for low or medium size databases. Nevertheless, tuning database parameters can greatly improve the performance and lead to very competitive runtimes.

Now in its 10th year, the Gramene database (http://www.gramene.org) has grown from its primary focus on rice, the first fully-sequenced grass genome, to become a resource for major model and crop plants including Arabidopsis, Brachypodium, maize, sorghum, poplar and grape in addition to several species of rice. Gramene began with the addition of an Ensembl genome browser and has expanded in the last decade to become a robust resource for plant genomics hosting a wide array of data sets including quantitative trait loci (QTL), metabolic pathways, genetic diversity, genes, proteins, germplasm, literature, ontologies and a fully-structured markers and sequences database integrated with genome browsers and maps from various published studies (genetic, physical, bin, etc.). In addition, Gramene now hosts a variety of web services including a Distributed Annotation Server (DAS), BLAST and a public MySQL database. Twice a year, Gramene releases a major build of the database and makes interim releases to correct errors or to make important updates to software and/or data.

Tools for knowledge acquisition within the NeuroScholar system and their application to anatomical tract-tracing data

Burns, Gully APC; Cheng, Wei-Cheng

2006-01-01

Background Knowledge bases that summarize the published literature provide useful online references for specific areas of systems-level biology that are not otherwise supported by large-scale databases. In the field of neuroanatomy, groups of small focused teams have constructed medium size knowledge bases to summarize the literature describing tract-tracing experiments in several species. Despite years of collation and curation, these databases only provide partial coverage of the available published literature. Given that the scientists reading these papers must all generate the interpretations that would normally be entered into such a system, we attempt here to provide general-purpose annotation tools to make it easy for members of the community to contribute to the task of data collation. Results In this paper, we describe an open-source, freely available knowledge management system called 'NeuroScholar' that allows straightforward structured markup of the PDF files according to a well-designed schema to capture the essential details of this class of experiment. Although, the example worked through in this paper is quite specific to neuroanatomical connectivity, the design is freely extensible and could conceivably be used to construct local knowledge bases for other experiment types. Knowledge representations of the experiment are also directly linked to the contributing textual fragments from the original research article. Through the use of this system, not only could members of the community contribute to the collation task, but input data can be gathered for automated approaches to permit knowledge acquisition through the use of Natural Language Processing (NLP). Conclusion We present a functional, working tool to permit users to populate knowledge bases for neuroanatomical connectivity data from the literature through the use of structured questionnaires. This system is open-source, fully functional and available for download from [1]. PMID:16895608

Trends in nursing ethics research: Mapping the literature production.

Blažun Vošner, Helena; Železnik, Danica; Kokol, Peter; Vošner, Janez; Završnik, Jernej

2017-12-01

There have been a number of debates in the field of nursing ethics. Researchers have focused on various aspects of nursing ethics, such as professional ethics, professional, nursing and ethical values. Within this research, a variety of literature reviews have been conducted, but to the best of our knowledge, bibliometric mapping has not yet been used. This article aims to analyse the production of literature within nursing ethics research. In order to examine publishing patterns, we focused on publishing dynamics, prolific research entities and the most-cited articles. We additionally visualised the content of the literature using a novel mixed-method approach, combining bibliometric analysis and mapping with thematic analysis. Ethical considerations: In our study, ethical review was not required. A total of 1416 information sources were found in the Scopus database. Overall, literature production has increased; however, in recent years, the quantity of published material has begun to decrease. The most prolific countries are the United States, the United Kingdom and Canada, and the most prolific source titles are Nursing Ethics, Journal of Advanced Nursing and Nursing Times. Lately, research in the field of nursing ethics has been focused more on life care (providing for the basic needs of older residents), moral distress and community nursing. The dynamics of research literature production showed an exponential rise in the number of published information sources - a rise which started in the period between 1974 and 1998. Since that period, the trend has stabilised, which might indicate that nursing ethics research is starting a transition to a mature phase. The innovative use of bibliometric analysis and mapping, together with thematic analysis, is a useful tool for analysis of research production in the field of nursing ethics. The results presented can be an excellent starting point for literature reviews and more exhaustive data, information and knowledge seeking.

Abstract MicroRNAs (miRNAs) are well-known as key regulators of diverse biological pathways. A series of experimental evidences have shown that abnormal miRNA expression profiles are responsible for various pathophysiological conditions by modulating genes in disease associated pathways. In spite of the rapid increase in research data confirming such associations, scientists still do not have access to a consolidated database offering these miRNA-pathway association details for critical diseases. We have developed miRwayDB, a database providing comprehensive information of experimentally validated miRNA-pathway associations in various pathophysiological conditions utilizing data collected from published literature. To the best of our knowledge, it is the first database that provides information about experimentally validated miRNA mediated pathway dysregulation as seen specifically in critical human diseases and hence indicative of a cause-and-effect relationship in most cases. The current version of miRwayDB collects an exhaustive list of miRNA-pathway association entries for 76 critical disease conditions by reviewing 663 published articles. Each database entry contains complete information on the name of the pathophysiological condition, associated miRNA(s), experimental sample type(s), regulation pattern (up/down) of miRNA, pathway association(s), targeted member of dysregulated pathway(s) and a brief description. In addition, miRwayDB provides miRNA, gene and pathway score to evaluate the role of a miRNA regulated pathways in various pathophysiological conditions. The database can also be used for other biomedical approaches such as validation of computational analysis, integrated analysis and prediction of computational model. It also offers a submission page to submit novel data from recently published studies. We believe that miRwayDB will be a useful tool for miRNA research community.

OBJECT Research conducted using large administrative data sets has increased in recent decades, but reports on the fidelity and reliability of such data have been mixed. The goal of this project was to compare data from a large, administrative claims data set with a quality improvement registry in order to ascertain similarities and differences in content. METHODS Data on children younger than 12 months with nonsyndromic craniosynostosis who underwent surgery in 2012 were queried in both the Kids' Inpatient Database (KID) and the American College of Surgeons Pediatric National Surgical Quality Improvement Program (Peds NSQIP). Data from published clinical craniosynostosis surgery series are reported for comparison. RESULTS Among patients younger than 12 months of age, a total of 1765 admissions were identified in KID and 391 in Peds NSQIP in 2012. Only nonsyndromic patients were included. The mean length of stay was 3.2 days in KID and 4 days in Peds NSQIP. The rates of cardiac events (0.5% in KID, 0.3% in Peds NSQIP, and 0.4%-2.2% in the literature), stroke/intracranial bleeds (0.4% in KID, 0.5% in Peds NSQIP, and 0.3%-1.2% in the literature), infection (0.2% in KID, 0.8% in Peds NSQIP, and 0%-8% in the literature), wound disruption (0.2% in KID, 0.5% in Peds NSQIP, 0%-4% in the literature), and seizures (0.7% in KID, 0.8% in Peds NSQIP, 0%-0.8% in the literature) were low and similar between the 2 data sets. The reported rates of blood transfusion (36% in KID, 64% in Peds NSQIP, and 1.7%-100% in the literature) varied between the 2 data sets. CONCLUSIONS Both the KID and Peds NSQIP databases provide large samples of surgical patients, with more cases reported in KID. The rates of complications studied were similar between the 2 data sets, with the exception of blood transfusion events where the retrospective chart review process of Peds NSQIP captured almost double the rate reported in KID.

Objectives. To systematically review and analyze the current status and characteristics of usability studies in China in the field of information technology in general and in the field of healthcare in particular. Methods. We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the concept of usability. Results. Six hundred forty-seven publications were selected for analysis. We found that in China the literature on usability in the field of information technology began in 1994 and increased thereafter. The usability definitions from ISO 9241-11:1998 and Nielsen (1993) have been widely recognized and cited. Authors who have published several publications are rare. Fourteen journals have a publishing rate over 1%. Only nine publications about HIT were identified. Discussions. China's usability research started relatively late. There is a lack of organized research teams and dedicated usability journals. High-impact theoretical studies are scarce. On the application side, no original and systematic research frameworks have been developed. The understanding and definition of usability is not well synchronized with international norms. Besides, usability research in HIT is rare. Conclusions. More human and material resources need to be invested in China's usability research, particularly in HIT. PMID:25050362

Folliculogenesis is an important part of ovarian function as it provides the oocytes for female reproductive life. Characterizing genes/proteins involved in folliculogenesis is fundamental for understanding the mechanisms associated with this biological function and to cure the diseases associated with folliculogenesis. A large number of genes/proteins associated with folliculogenesis have been identified from different species. However, no dedicated public resource is currently available for folliculogenesis-related genes/proteins that are validated by experiments. Here, we are reporting a database 'Follicle Online' that provides the experimentally validated gene/protein map of the folliculogenesis in a number of species. Follicle Online is a web-based database system for storing and retrieving folliculogenesis-related experimental data. It provides detailed information for 580 genes/proteins (from 23 model organisms, including Homo sapiens, Mus musculus, Rattus norvegicus, Mesocricetus auratus, Bos Taurus, Drosophila and Xenopus laevis) that have been reported to be involved in folliculogenesis, POF (premature ovarian failure) and PCOS (polycystic ovary syndrome). The literature was manually curated from more than 43,000 published articles (till 1 March 2014). The Follicle Online database is implemented in PHP + MySQL + JavaScript and this user-friendly web application provides access to the stored data. In summary, we have developed a centralized database that provides users with comprehensive information about genes/proteins involved in folliculogenesis. This database can be accessed freely and all the stored data can be viewed without any registration. Database URL: http://mcg.ustc.edu.cn/sdap1/follicle/index.php © The Author(s) 2015.

Background Oral submucous fibrosis (OSF) is an insidious chronic condition characterized by restricted mouth opening. Prosthetic rehabilitation is challenging for OSF patients as obtaining a good impression requires adequate mouth opening. The aim of the present review is to systematically present the data from case reports published in the English-language literature. Method A comprehensive search of the literature databases (PubMed, Medline, SCOPUS, Web of Science and Google Scholar) along with the references of published articles on prosthetic rehabilitation in OSF patients published to date was conducted. Keywords included a combination of ‘Oral submucous fibrosis’, ‘prosthesis’, ‘dentures’ and/or ‘restricted mouth opening’. Citations from selected references and bibliographic linkages taken from similar cases were included in this review. The inclusion criteria selected for case reports on prosthetic rehabilitation in OSF patients, and cases of restricted mouth opening due to causes other than OSF were excluded from the study. Results A total of 21 cases were identified and analysed from 17 papers published in the English-language literature. Of these, 9 cases employed the sectional denture technique, 4 cases emphasized the need-based treatment approach in which conventional methods were modified, and 4 cases used mouth exercising devices. Finally, 1 case each involved, flexible denture, oral screen prosthesis, oral stents, surgery in conjunction with dentures. Conclusion Prosthetic rehabilitation in OSF patients is a multifaceted approach and should be patient specific, although sectional dentures have achieved the best results. PMID:28877246

We aimed to determine the quantity and quality of research output of selected Asian countries in the field of total knee arthroplasty (TKA) in the last 10 years. Top 15 Asian countries were selected according to their gross domestic product. The Science Citation Index Expanded database was used to search for the literature published between 2004 and 2013 using "Total Knee Arthroplasty". The numbers of articles, journals and citations and the contribution of each country were analyzed. The articles were classified according to the type of study and the relative proportion of each type was analyzed. Asian surgeons have increasingly contributed to orthopedic literature on TKA for the past 10 years, but the dominant contribution came from only a few countries. The total number of articles published by Asian countries increased by 261%, with Japan producing most of the studies and China showing the maximum growth rate. The majority of studies were published in low impact factor journals. Korea published the highest proportion of articles in high impact factor journals. Clinical papers were most frequent. Our identification of research productivity pertaining to TKA among Asian countries gives a unique insight into the level of academic research in the field of TKA in these countries. There is a need to improve the quality of research to enhance the publishing power in high impact journals as well as the need for more basic research and epidemiological studies considering the unique differences among Asian patients undergoing TKA.

2010-12-01

The purpose of our study was to describe the dissemination of research into the clinical nursing literature. The literature provides a means of transferring knowledge from a research study through citations of the work by other authors. This was a citation analysis study to explore the dissemination of research into the clinical nursing literature, beginning with the publication of an original research study and including all of the citations to that article through 2009. The authors searched five academic nursing research journal titles, using CINAHL, for original research reports that had clinical relevance and were published between 1990-1999. The search process yielded a final data set of 28 research articles. For each of the articles, the authors searched three databases, CINAHL, Web of Science(®) and Google Scholar, to determine the citation patterns from the date of publication to August 2009. All of the research studies were cited in articles published in clinical journals although there was a wide range in the number of citations, from 3-80. The 28 research articles had a total of 759 citations; 717 (94.5%) of those citations were in articles published in clinical nursing journals. The median length of time between publication of the original study and the first citation was 1.5 years. Some of the studies were still being cited for 18 years after publication of the original work. All of the original research reports examined in this study were cited in articles in clinical journals, disseminating the research beyond the original work to reach clinicians. Clinical nursing journals keep readers up-to-date and informed about new practices in nursing and serve another important role: they disseminate research that is clinically relevant by publishing original studies and papers that cite research reports. © 2010 Blackwell Publishing Ltd.

2014-03-01

Central granular cell odontogenic tumor (CGCOT) is a rare benign odontogenic neoplasm reported with various terms and is not included in the 2005 WHO classification of odontogenic tumors. It shows a predilection for middle-aged women, usually presenting as an asymptomatic swelling of the mandibular premolar-molar region. Radiographic manifestations include unilocular or multilocular radiolucent lesion, but mixed density lesions can also occur. Histopathology shows sheets and lobules of round to polygonal cells with abundant eosinophilic, granular cytoplasm and eccentrically placed nuclei. Immunohistochemical and ultrastructural features suggest the histiocytic origin of granular cells. The neoplasm does not exhibit an aggressive biological behavior and hence enucleation or curettage ensuring complete removal remains the treatment of choice. We present a systematic review on clinical, radiological, histopathological, immunohistochemical and treatment aspect of CGCOT. Published articles were identified through a literature search using online databases (PubMed, MEDLINE, Scopus) and cross-references for papers published from the year 1950 to March 2013. From a total of 37 papers, 26 (38 cases) were extracted from the database for systematic review. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The prevalence of trauma histories and related psychological problems is high in general clinical settings, but little is known about trauma patient preferences for mental health treatment. The purpose of this article is to systematically review and synthesize the literature on treatment preferences in survivors of traumatic events. Studies were identified using comprehensive searches of PsycINFO, Medline, PubMed, Published International Literature on Traumatic Stress, and Cumulative Index to Nursing and Allied Health Literature databases. Included in the review were articles published between January 1980 and September 2014, in English that reported patient preference of treatment for trauma related disorders in either clinical or nonclinical (e.g., analog) samples. The total number of individual participants was 6,091. Of the identified studies, 35 were quantitative and 6 were qualitative. Methodological concerns included the use of analog samples, small sample sizes, and the assessment of a limited number of treatment options (e.g., asking about only 1 type of psychotherapy or medication). Overall, participants expressed a preference for psychotherapy over medication and for talking about their trauma. Understanding and addressing trauma patient preferences may assist in improving treatment initiation as well as facilitate engagement, retention and outcome. (c) 2015 APA, all rights reserved).

2016-02-01

A limited number of clinical studies have investigated the effectiveness of participation in exercise training programmes for patients with multiple myeloma (MM), exploring the different biomedical, physical, psychological and quality of life. The aim of this literature review is to evaluate current quantitative and qualitative evidence concerning the effectiveness of participation in exercise programmes for patients with MM in improving physiological and/or psychological status. A literature search encompassing studies published between January 1998 and July 2013 was conducted through ten electronic databases. This search was further expanded through citation chaining, manual grey literature searches, and peer review consultation. In total, seven interventional studies were identified and appraised using Critical Appraisal Skill Programme (CASP) or Centre for Evidence-Based Management of Amsterdam (CEBMa). Though the majority of the studies presented encouraging data, however, three studies that implemented individualized exercise interventions for patients at different stages of MM and myeloablative treatment showed mixed results. In conclusion, the effectiveness of participation in exercise programmes remains unclear for patients with MM, as the studies reviewed were flawed by relatively weak methodological approaches.

Literature search strategies for conducting knowledge-building and theory-generating qualitative systematic reviews.

PubMed

2013-01-01

To report literature search strategies for the purpose of conducting knowledge-building and theory-generating qualitative systematic reviews. Qualitative systematic reviews lie on a continuum from knowledge-building and theory-generating to aggregating and summarizing. Different types of literature searches are needed to optimally support these dissimilar reviews. Articles published between 1989-Autumn 2011. These documents were identified using a hermeneutic approach and multiple literature search strategies. Redundancy is not the sole measure of validity when conducting knowledge-building and theory-generating systematic reviews. When conducting these types of reviews, literature searches should be consistent with the goal of fully explicating concepts and the interrelationships among them. To accomplish this objective, a 'berry picking' approach is recommended along with strategies for overcoming barriers to finding qualitative research reports. To enhance integrity of knowledge-building and theory-generating systematic reviews, reviewers are urged to make literature search processes as transparent as possible, despite their complexity. This includes fully explaining and rationalizing what databases were used and how they were searched. It also means describing how literature tracking was conducted and grey literature was searched. In the end, the decision to cease searching also needs to be fully explained and rationalized. Predetermined linear search strategies are unlikely to generate search results that are adequate for purposes of conducting knowledge-building and theory-generating qualitative systematic reviews. Instead, it is recommended that iterative search strategies take shape as reviews evolve. © 2012 Blackwell Publishing Ltd.

2015-03-01

The aim of this study is to identify ethical problems experienced by nurses in primary health care and resources for coping based on publications on the subject. An integrative literature review was performed between the months of October and November 2013, using the databases: BDTD, CINAHL, LILACS, MEDLINE, Biblioteca Cochrane, PubMed, RCAAP and SciELO. Articles, dissertations and theses published in Portuguese, English and Spanish were included, totalling 31 studies published from 1992 to 2013. This analysis resulted in four categories: ethical problems in the relationship between team members, ethical problems in the relationship with the user, ethical problems in health services management and resources for coping with ethical problems. Results showed that nurses need to be prepared to face ethical problems, emphasizing the importance of ethics education during the education process before and during professional practice to enhance the development of ethical sensitivity and competence for problem resolution.

Pathology Consultation on Viscoelastic Studies of Coagulopathic Obstetrical Patients.

Gehrie, Eric A; Baine, Ian; Booth, Garrett S

2016-08-01

In obstetrics, the decision to transfuse blood components has historically been driven by traditional laboratory testing in combination with direct observation of bleeding. The adjunctive use of viscoelastic testing, including thromboelastometry and thromboelastography, has gained increasing acceptance in the clinical domain. We performed a review of the published medical literature by searching the PUBMED database for keywords "viscoelastic" and "obstetric," as well as "viscoelastic" and "postpartum hemorrhage." Additionally, case reports and expert opinion publications that referenced viscoelastic studies in obstetrical patients were evaluated. There is very little high-quality evidence currently published in the medical literature to support the notion that viscoelastic testing obviates the need for traditional coagulation testing or improves mortality resulting from major obstetrical hemorrhage. Additional research is needed to further focus the optimum role of viscoelastic tests in major obstetrical hemorrhage. © American Society for Clinical Pathology, 2016. All rights reserved.

The aim of this study was to develop and validate a community supported online infrastructure and bioresource for methane yield data and accompanying metadata collected from published literature. In total, 1164 entries described by 15,749 data points were assembled. Analysis of data collection showed little congruence in reporting of methodological approaches. The largest identifiable source of variation in reported methane yields was represented by authorship (i.e. substrate batches within particular substrate class) within which experimental scales (volumes (0.02-5l), incubation temperature (34-40 °C) and % VS of substrate played an important role (p < 0.05, npermutations = 999) as well. The largest fraction of variability, however, remained unaccounted for and thus unexplained (> 63%). This calls for reconsideration of accepted approaches to reporting data in currently published literature to increase capacity to service industrial decision making to a greater extent.

Nurses are learning and practicing in an increasingly global world. Both nursing schools and nursing students are seeking guidance as they integrate global health into their learning and teaching. This systematic review is intended to identify the most common global and public health core competencies found in the literature and better inform schools of nursing wishing to include global health content in their curricula. Systematic review. An online search of CINAHL and Medline databases, as well as, inclusion of pertinent gray literature was conducted for articles published before 2013. Relevant literature for global health (GH) and public and community health (PH/CH) competencies was reviewed to determine recommendations of both competencies using a combination of search terms. Studies must have addressed competencies as defined in the literature and must have been pertinent to GH or PH/CH. The databases were systematically searched and after reading the full content of the included studies, key concepts were extracted and synthesized. Twenty-five studies were identified and resulted in a list of 14 global health core competencies. These competencies are applicable to a variety of health disciplines, but particularly can inform the efforts of nursing schools to integrate global health concepts into their curricula.

Building a protein name dictionary from full text: a machine learning term extraction approach.

Shi, Lei; Campagne, Fabien

2005-04-07

The majority of information in the biological literature resides in full text articles, instead of abstracts. Yet, abstracts remain the focus of many publicly available literature data mining tools. Most literature mining tools rely on pre-existing lexicons of biological names, often extracted from curated gene or protein databases. This is a limitation, because such databases have low coverage of the many name variants which are used to refer to biological entities in the literature. We present an approach to recognize named entities in full text. The approach collects high frequency terms in an article, and uses support vector machines (SVM) to identify biological entity names. It is also computationally efficient and robust to noise commonly found in full text material. We use the method to create a protein name dictionary from a set of 80,528 full text articles. Only 8.3% of the names in this dictionary match SwissProt description lines. We assess the quality of the dictionary by studying its protein name recognition performance in full text. This dictionary term lookup method compares favourably to other published methods, supporting the significance of our direct extraction approach. The method is strong in recognizing name variants not found in SwissProt.

Body integrity identity disorder crosses culture: case reports in the Japanese and Chinese literature.

Body integrity identity disorder (BIID) is a condition in which people do not perceive a part of their body as their own, which results in a strong desire for amputation or paralyzation. The disorder is likely to be congenital due to its very early onset. The English literature describes only Western patients with BIID, suggesting that the disorder might be merely prevalent in the West. To scrutinize this assumption, and to extend our knowledge of the etiology of BIID, it is important to trace cases with BIID in non-Western populations. Our objective was to review Chinese and Japanese literature on BIID to learn about its presence in populations with a different genetic background. A systematic literature search was performed in databases containing Japanese and Chinese research, published in the respective languages. Five Japanese articles of BIID were identified which described two cases of BIID, whereas in the Chinese databases only BIID-related conditions were found. This article reports some preliminary evidence that BIID is also present in non-Western countries. However, making general statements about the biological background of the disorder is hampered by the extremely low number of cases found. This low number possibly resulted from the extreme secrecy associated with the disorder, perhaps even more so in Asian countries.

The Oklahoma Geological Survey (OGS), the Geological Information Systems department, and the School of Petroleum and Geological Engineering at the University of Oklahoma are engaged in a five-year program to identify and address Oklahoma`s oil recovery opportunities in fluvial-dominated deltaic (FDD) reservoirs. This program includes the systematic and comprehensive collection, evaluation, and distribution of information on all of Oklahoma`s FDD oil reservoirs and the recovery technologies that can be applied to those reservoirs with commercial success. Exhaustive literature searches are being conducted for these plays, both through published sources and through unpublished theses from regional universities. A bibliographic database hasmore » been developed to record these literature sources and their related plays. Trend maps are being developed to identify the FDD portions of the relevant reservoirs, through accessing current production databases and through compiling the literature results. A reservoir database system also has been developed, to record specific reservoir data elements that are identified through the literature, and through public and private data sources. Thus far, the initial demonstration for one has been completed, and second is nearly completed. All of the information gathered through these efforts will be transferred to the Oklahoma petroleum industry through a series of publications and workshops. Additionally, plans are being developed, and hardware and software resources are being acquired, in preparation for the opening of a publicly-accessible computer users laboratory, one component of the technology transfer program.« less

Fei-Liu-Ping ointment has been widely applied as adjunctive drug in the treatment of non-small cell lung cancer (NSCLC). However, there has been no systematic review of research findings regarding the efficacy of this treatment. Here, we provide a protocol for assessing the effectiveness and safety of Fei-Liu-Ping ointment in the treatment of NSCLC. The electronic databases to be searched will include MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, Excerpt Medica Database (EMBASE), China National Knowledge Infrastructure (CNKI), China Scientific Journal Database (VIP), Wanfang Database and Chinese Biomedical Literature Database (CBM). Papers in English or Chinese published from inception to 2016 will be included without any restrictions. We will conduct a meta-analysis of randomised controlled trial if possible. The therapeutic effects according to the standard for treatment of solid tumours by the WHO and the quality of life as evaluated by Karnofsky score and weight will be applied as the primary outcomes. We will also evaluate the data synthesis and risk of bias using Review Manager 5.3 software. The results of this review will offer implications for the use of Fei-Liu-Ping ointment as an adjunctive treatment for NSCLC. This knowledge will inform recommendations by surgeons and researchers who are interested in the treatment of NSCLC. The results of this systematic review will be disseminated through presentation at a conference and publication of the data in a peer-reviewed journal. PROSPERO CRD42016036911.

Systematic reviews (SRs) and meta-analyses (MAs) of nursing interventions have become increasingly popular in China. This review provides the first examination of epidemiological characteristics of these SRs as well as compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses and Assessment of Multiple Systematic Reviews guidelines. The purpose of this study was to examine epidemiologic and reporting characteristics as well as the methodologic quality of SRs and MAs of nursing interventions published in Chinese journals. Four Chinese databases were searched (the Chinese Biomedicine Literature Database, Chinese Scientific Journal Full-text Database, Chinese Journal Full-text Database, and Wanfang Database) for SRs and MAs of nursing intervention from inception through June 2013. Data were extracted into Excel (Microsoft, Redmond, WA). The Assessment of Multiple Systematic Reviews and Preferred Reporting Items for Systematic Reviews and Meta-analyses checklists were used to assess methodologic quality and reporting characteristics, respectively. A total of 144 SRs were identified, most (97.2%) of which used "systematic review" or "meta-analyses" in the titles. None of the reviews had been updated. Nearly half (41%) were written by nurses, and more than half (61%) were reported in specialist journals. The most common conditions studied were endocrine, nutritional and metabolic diseases, and neoplasms. Most (70.8%) reported information about quality assessment, whereas less than half (25%) reported assessing for publication bias. None of the reviews reported a conflict of interest. Although many SRs of nursing interventions have been published in Chinese journals, the quality of these reviews is of concern. As a potential key source of information for nurses and nursing administrators, not only were many of these reviews incomplete in the information they provided, but also some results were misleading. Improving the quality of SRs of nursing interventions conducted and published by nurses in China is urgently needed in order to increase the value of these studies. Copyright © 2015 Elsevier Inc.

2016-06-15

Synonymous mutations (SMs), which changed the sequence of a gene without directly altering the amino acid sequence of the encoded protein, were thought to have no functional consequences for a long time. They are often assumed to be neutral in models of mutation and selection and were completely ignored in many studies. However, accumulating experimental evidence has demonstrated that these mutations exert their impact on gene functions via splicing accuracy, mRNA stability, translation fidelity, protein folding and expression, and some of these mutations are implicated in human diseases. To the best of our knowledge, there is still no database specially focusing on disease-related SMs. We have developed a new database called dbDSM (database of Deleterious Synonymous Mutation), a continually updated database that collects, curates and manages available human disease-related SM data obtained from published literature. In the current release, dbDSM collects 1936 SM-disease association entries, including 1289 SMs and 443 human diseases from ClinVar, GRASP, GWAS Catalog, GWASdb, PolymiRTS database, PubMed database and Web of Knowledge. Additionally, we provided users a link to download all the data in the dbDSM and a link to submit novel data into the database. We hope dbDSM will be a useful resource for investigating the roles of SMs in human disease. dbDSM is freely available online at http://bioinfo.ahu.edu.cn:8080/dbDSM/index.jsp with all major browser supported. jfxia@ahu.edu.cn Supplementary data are available at Bioinformatics online. © The Author 2016.

Domain-specific databases are essential resources for the biomedical community, leveraging expert knowledge to curate published literature and provide access to referenced data and knowledge. The limited scope of these databases, however, poses important challenges on their infrastructure, visibility, funding and usefulness to the broader scientific community. CollecTF is a community-oriented database documenting experimentally validated transcription factor (TF)-binding sites in the Bacteria domain. In its quest to become a community resource for the annotation of transcriptional regulatory elements in bacterial genomes, CollecTF aims to move away from the conventional data-repository paradigm of domain-specific databases. Through the adoption of well-established ontologies, identifiers and collaborations, CollecTF has progressively become also a portal for the annotation and submission of information on transcriptional regulatory elements to major biological sequence resources (RefSeq, UniProtKB and the Gene Ontology Consortium). This fundamental change in database conception capitalizes on the domain-specific knowledge of contributing communities to provide high-quality annotations, while leveraging the availability of stable information hubs to promote long-term access and provide high-visibility to the data. As a submission portal, CollecTF generates TF-binding site information through direct annotation of RefSeq genome records, definition of TF-based regulatory networks in UniProtKB entries and submission of functional annotations to the Gene Ontology. As a database, CollecTF provides enhanced search and browsing, targeted data exports, binding motif analysis tools and integration with motif discovery and search platforms. This innovative approach will allow CollecTF to focus its limited resources on the generation of high-quality information and the provision of specialized access to the data.Database URL: http://www.collectf.org/. © The Author(s) 2016.

Libraries will be changed by technological and social developments that are fueled by information technology, bioinformatics, and networked information. Libraries in highly focused settings such as the health sciences are at a pivotal point in their development as the synthesis of historically diverse and independent information sources transforms health care institutions. Boundaries are breaking down between published literature and research data, between research databases and clinical patient data, and between consumer health information and professional literature. This paper focuses on the dynamics that are occurring with networked information sources and the roles that libraries will need to play in the world of medical informatics in the early twenty-first century.

To identify the composition of the smoke produced by electrocautery use during surgery. Integrative review with search for primary studies conducted in the databases of the US National Library of Medicine National Institutes of Health, Cumulative Index to Nursing and Allied Health Literature, and Latin American and Caribbean Health Sciences, covering the studies published between 2004 and 2014. The final sample consisted of 14 studies grouped into three categories, namely; polycyclic aromatic hydrocarbons, volatile compounds and volatile organic compounds. There is scientific evidence that electrocautery smoke has volatile toxic, carcinogenic and mutagenic compounds, and its inhalation constitutes a potential chemical risk to the health of workers involved in surgeries.

To survey the distribution pattern and subject domain knowledge of worldwide glaucoma research based on literatures in Pubmed database. Literatures on glaucoma published in 2007 to 2011 were identified in Pubmed database. The analytic items of an article include published year, country, language author, and journal. After core mesh terms had been characterized by BICOMS, the co-occurrence matrix was built. Cluster analysis was finished by SPSS 20.0. Then visualized network was drawn using ucinet 6.0. Totally 6427 literatures were included, the number of annual articles changed slightly between 2007 and 2011. The United States, England, Germany, Australia, and France together accounted for 77.63% of articles. There were 52 high-frequency subjects and hot topics were clustered into the following 10 categories: (1) Pathology of optic disc and nerve fibers and OCT application, (2) METHODS: of visual field (VF) and visual function examination, (3) Glaucoma drug medications, (4) Pathology and physiology of primary open angle glaucoma (POAG) including VF and intraocular pressure (IOP), (5) Glaucoma surgery, (6) Gene research related to POAG, (7) Glaucoma disease pathology and animal models, (8) Ocular hypertension (OHT) induced complications and corneal changes, (9) Etiology of congenital glaucoma and complications, (10) Etiology and epidemiology of glaucoma. The visualized domain knowledge mapping was successfully built. The pathology of optic disc and nerve fibers, medications, and surgery were well developed. Study on IOP and visual field was in the core domain, which have an important link to etiology, diagnosis, and therapy. The researches on glaucomatous gene, disease pathology model, congenital glaucoma, etiology and epidemiology were not developed well, which are of great promotion space. The distribution pattern and subject domain knowledge of worldwide glaucoma research in the recent five years were shown by using bibliometric analysis.Western developed countries play a leading role in the field of glaucoma research, the international influence of related research in China needs to be strengthened.

In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required. Here we present the Mammalian Feeding Muscle Ontology (MFMO), a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED, https://feedexp.org/), a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing) in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions). We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar. Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive set of results can be obtained. The broader scientific and publishing communities should consider taking up the challenge of semantically enabled search capabilities.

[The methods within the evaluation of disease management programmes in control-group designs using the example of diabetes mellitus - a systematic literature review].

Disease management programmes (DMPs) were implemented in Germany in 2002. Their evaluation is required by law. Beyond the mandatory evaluation, a growing number of published studies evaluate the DMP for diabetes mellitus type 2 in a control-group design. As patients opt into the programme on a voluntary basis it is necessary to adjust the inherent selection bias between groups. The aim of this study is to review published studies which evaluate the diabetes DMP using a control-group design with respect to the methods used. A systematic literature review of electronic databases (PUBMED, Cochrane Library, EMBASE, MEDPILOT) and a hand search of reference lists of the relevant publications was conducted to identify studies evaluating the DMP diabetes mellitus in a control-group design. 8 studies were included in the systematic literature review. 4 studies gathered retrospective claims data from sickness funds, one from physician's records, one study used prospective data from ambulatory care, and 2 studies were based on one patient survey. Methods used for adjustment of selection bias included exact matching, matching using propensity score methods, age-adjusted and sex-separated analysis, and adjustment in a regression model/analysis of covariance. One study did not apply adjustment methods. The intervention period ranged from 1 day to 4 years. Considered outcomes of studies (surrogate parameter, diabetes complications, mortality, quality of life, and claim data) depended on the database. In the evaluation of the DMP diabetes mellitus based on a control-group design neither the database nor the methods used for selection bias adjustment were consistent in the available studies. Effectiveness of DMPs cannot be judged based on this review due to heterogeneity of study designs. To allow for a comprehensive programme evaluation standardised minimum requirements for the evaluation of DMPs in the control group design are required. © Georg Thieme Verlag KG Stuttgart · New York.

Literature-Based Gene Curation and Proposed Genetic Nomenclature for Cryptococcus

Cryptococcus, a major cause of disseminated infections in immunocompromised patients, kills over 600,000 people per year worldwide. Genes involved in the virulence of the meningitis-causing fungus are being characterized at an increasing rate, and to date, at least 648 Cryptococcus gene names have been published. However, these data are scattered throughout the literature and are challenging to find. Furthermore, conflicts in locus identification exist, so that named genes have been subsequently published under new names or names associated with one locus have been used for another locus. To avoid these conflicts and to provide a central source of Cryptococcus gene information, we have collected all published Cryptococcus gene names from the scientific literature and associated them with standard Cryptococcus locus identifiers and have incorporated them into FungiDB (www.fungidb.org). FungiDB is a panfungal genome database that collects gene information and functional data and provides search tools for 61 species of fungi and oomycetes. We applied these published names to a manually curated ortholog set of all Cryptococcus species currently in FungiDB, including Cryptococcus neoformans var. neoformans strains JEC21 and B-3501A, C. neoformans var. grubii strain H99, and Cryptococcus gattii strains R265 and WM276, and have written brief descriptions of their functions. We also compiled a protocol for gene naming that summarizes guidelines proposed by members of the Cryptococcus research community. The centralization of genomic and literature-based information for Cryptococcus at FungiDB will help researchers communicate about genes of interest, such as those related to virulence, and will further facilitate research on the pathogen.

The aim of this review was to assess the current evidence regarding the efficacy of teaching skills programs for junior medical officers. We aimed to compare and contrast these results with findings from previous literature reviews, the last of which were published in 2009. In order to capture studies since the last published literature reviews, five databases and grey literature were searched for publications from January 2008 to January 2015. A search for literature reviews without using the timeframe limitation was also performed. The search from January 2008 to January 2015 resulted in the inclusion of 12 studies. Five systematic reviews of the topic were found which included 39 individual studies that were also analysed. Nearly all studies reported positive effects. Twenty nine studies reported change in attitudes, 28 reported modification in knowledge, 28 reported change in behaviour, 6 reported change in the organisation and two reported change in program participant's students. There were substantial threats of bias present. The literature reviewed demonstrated many positive effects of teaching skills programs, which supports their utilization. However, high level outcomes need to be evaluated over longer periods of time to establish their true impact. An organisation specific approach to these programs needs to occur using sound course design principles, and they need to be reported in evaluation trials that are designed with robust methodology.

The face is an important part of the human body by which an individual communicates in the society. Its importance can be highlighted by the fact that a person deprived of face cannot sustain in the living world. The amount of experiments being performed and the number of research papers being published under the domain of human face have surged in the past few decades. Several scientific disciplines, which are conducting research on human face include: Medical Science, Anthropology, Information Technology (Biometrics, Robotics, and Artificial Intelligence, etc.), Psychology, Forensic Science, Neuroscience, etc. This alarms the need of collecting and managing the data concerning human face so that the public and free access of it can be provided to the scientific community. This can be attained by developing databases and tools on human face using bioinformatics approach. The current research emphasizes on creating a database concerning literature data of human face. The database can be accessed on the basis of specific keywords, journal name, date of publication, author's name, etc. The collected research papers will be stored in the form of a database. Hence, the database will be beneficial to the research community as the comprehensive information dedicated to the human face could be found at one place. The information related to facial morphologic features, facial disorders, facial asymmetry, facial abnormalities, and many other parameters can be extracted from this database. The front end has been developed using Hyper Text Mark-up Language and Cascading Style Sheets. The back end has been developed using hypertext preprocessor (PHP). The JAVA Script has used as scripting language. MySQL (Structured Query Language) is used for database development as it is most widely used Relational Database Management System. XAMPP (X (cross platform), Apache, MySQL, PHP, Perl) open source web application software has been used as the server.The database is still under the developmental phase and discusses the initial steps of its creation. The current paper throws light on the work done till date.

Background Knowing the levels of polyamines (putrescine, spermidine, and spermine) in different foods is of interest due to the association of these bioactive nutrients to health and diseases. There is a lack of relevant information on their contents in foods. Objective To develop a food polyamine database from published data by which polyamine intake and food contribution to this intake can be estimated, and to determine the levels of polyamines in Swedish dairy products. Design Extensive literature search and laboratory analysis of selected Swedish dairy products. Polyamine contents in foods were collected using an extensive literature search of databases. Polyamines in different types of Swedish dairy products (milk with different fat percentages, yogurt, cheeses, and sour milk) were determined using high performance liquid chromatography (HPLC) equipped with a UV detector. Results Fruits and cheese were the highest sources of putrescine, while vegetables and meat products were found to be rich in spermidine and spermine, respectively. The content of polyamines in cheese varied considerably between studies. In analyzed Swedish dairy products, matured cheese had the highest total polyamine contents with values of 52.3, 1.2, and 2.6 mg/kg for putrescine, spermidine, and spermine, respectively. Low fat milk had higher putrescine and spermidine, 1.2 and 1.0 mg/kg, respectively, than the other types of milk. Conclusions The database aids other researchers in their quest for information regarding polyamine intake from foods. Connecting the polyamine contents in food with the Swedish Food Database allows for estimation of polyamine contents per portion. PMID:21249159

To evaluate the effect of 3D printing technology applied in the surgical treatment of pelvic fractures through the published literatures by Meta-analysis. The PubMed database, EMCC database, CBM database, CNKI database, VIP database and Wanfang database were searched from the date of database foundation to August 2017 to collect the controlled clinical trials in wich 3D printing technology was applied in preoperative planning of pelvic fracture surgery. The retrieved literatures were screened according to predefined inclusion and exclusion criteria, and quality evaluation were performed. Then, the available data were extracted and analyzed with the RevMan5.3 software. Totally 9 controlled clinical trials including 638 cases were chosen. Among them, 279 cases were assigned to the 3D printing technology group and 359 cases to the conventional group. The Meta-analysis results showed that the operative time[SMD=-2.81, 95%CI(-3.76, -1.85)], intraoperative blood loss[SMD=-3.28, 95%CI(-4.72, -1.85)] and the rate of complication [OR=0.47, 95%CI(0.25, 0.87)] in the 3D printing technology were all lower than those in the conventional group;the excellent and good rate of pelvic fracture reduction[OR=2.09, 95%CI(1.32, 3.30)] and postoperative pelvic functional restoration [OR=1.94, 95%CI(1.15, 3.28) in the 3D printing technology were all superior to those in the conventional group. 3D printing technology applied in the surgical treatment of pelvic fractures has the advantage of shorter operative time, less intraoperative blood loss and lower rate of complication, and can improve the quality of pelvic fracture reduction and the recovery of postoperative pelvic function.

We investigated a pulmonary adverse drug reaction possibly induced by fluoxetine, the Interstitial Lung Disease, by performing a systematic review of published case reports on this subject, a review of the World Health Organization VigiAccess database, of the European EudraVigilance database and of a national Pharmacovigilance database (Italian Pharmacovigilance Network). The research found a total of seven cases linking fluoxetine to Interstitial Lung Disease in the literature. 36 cases of interstitial lung disease related to fluoxetine were retrieved from the VigiAccess database (updated to July 2016), and 36 reports were found in EudraVigilance database (updated to June 2016). In the Italian Pharmacovigilance database (updated to August 2016), we found only one case of Interstitial Lung Disease, codified as "pulmonary disease". Our investigation shows that fluoxetine might be considered as a possible cause of Interstitial Lung Disease. In particular, although here we do not discuss the assessment of benefits and harms of fluoxetine, since this antidepressant is widely used, our review suggests that fluoxetine-induced Interstitial Lung Disease should be considered in patients with dyspnea, associated or not with dry cough, who are treated with this drug. An early withdrawn of fluoxetine could be useful to obtain a complete remission of this adverse drug reaction and special attention should be particularly devoted to long-term therapy, and to female and elderly patients. Although the spontaneous reporting system is affected by important limitations, drug post- marketing surveillance represents an important tool to evaluate the real world effectiveness and safety of drugs.

Barbosa, Fabiana G

2014-09-01

Limnoperna fortunei (golden mussel) is a freshwater bivalve native to Southeast Asia, but is becoming an invasive species in several aquatic ecosystems in the world. In this study, a scientometric analysis was performed to identify the patterns, trends and gaps of knowledge for this invasive species. A survey of the published literature was conducted using the database of the Thomson Institute for Scientific Information (ISI). A total of 107 papers were surveyed that were published between 1982 and 2012 in 60 journals. The number of papers on L. fortunei over the years has increased, especially within the last eight years of the study period. Argentina, Brazil, and Japan are the countries that contributed the most papers to the literature on invasive bivalve. The majority of papers were field-observational studies. Among some important gaps that need to be addressed are the relatively small number and/or lack of studies conducted in the native countries and in countries invaded by L. fortunei, the lack of internationally collaborative publications in these countries, as well as a low number of internationally collaborative studies.

Dawson, Gretchen; Madsen, Lydia T; Dains, Joyce E

2016-12-01

Fear of cancer recurrence (FCR) is one of the largest unmet needs in the breast cancer survivor population. This review addresses this unmet need with the question. The purpose of this article is to better understand potential interventions to manage FCR when caring for breast cancer survivors. Databases used were PubMed, CINAHL®, Google Scholar, EMBASE, and Scopus. Articles published in English from 2009-2014 with female breast cancer survivors and interventions that address FCR as an endpoint or outcome measure or objectively illustrate an improvement in FCR were included. One hundred ninety-eight articles were initially identified in this literature review search. Upon detailed review of content for relevance, seven articles met criteria to be included in this review. This literature review provided current evidence of published interventions to manage uncertainty in the female breast cancer survivor population, as well as future research recommendations. Interventions surrounding being mindful, managing uncertainty, having more effective patient-provider communication, and handling stress through counseling are options for managing FCR.

Systematic review finds that study data not published in full text articles have unclear impact on meta-analyses results in medical research.

A meta-analysis as part of a systematic review aims to provide a thorough, comprehensive and unbiased statistical summary of data from the literature. However, relevant study results could be missing from a meta-analysis because of selective publication and inadequate dissemination. If missing outcome data differ systematically from published ones, a meta-analysis will be biased with an inaccurate assessment of the intervention effect. As part of the EU-funded OPEN project (www.open-project.eu) we conducted a systematic review that assessed whether the inclusion of data that were not published at all and/or published only in the grey literature influences pooled effect estimates in meta-analyses and leads to different interpretation. Systematic review of published literature (methodological research projects). Four bibliographic databases were searched up to February 2016 without restriction of publication year or language. Methodological research projects were considered eligible for inclusion if they reviewed a cohort of meta-analyses which (i) compared pooled effect estimates of meta-analyses of health care interventions according to publication status of data or (ii) examined whether the inclusion of unpublished or grey literature data impacts the result of a meta-analysis. Seven methodological research projects including 187 meta-analyses comparing pooled treatment effect estimates according to different publication status were identified. Two research projects showed that published data showed larger pooled treatment effects in favour of the intervention than unpublished or grey literature data (Ratio of ORs 1.15, 95% CI 1.04-1.28 and 1.34, 95% CI 1.09-1.66). In the remaining research projects pooled effect estimates and/or overall findings were not significantly changed by the inclusion of unpublished and/or grey literature data. The precision of the pooled estimate was increased with narrower 95% confidence interval. Although we may anticipate that systematic reviews and meta-analyses not including unpublished or grey literature study results are likely to overestimate the treatment effects, current empirical research shows that this is only the case in a minority of reviews. Therefore, currently, a meta-analyst should particularly consider time, effort and costs when adding such data to their analysis. Future research is needed to identify which reviews may benefit most from including unpublished or grey data.

Corvids (Corvidae) play a major role in ornithological research. Because of their worldwide distribution, diversity and adaptiveness, they have been studied extensively. The aim of the Corvids Literature Database (CLD, http://www.corvids.de/cld) is to record all publications (citation format) on all extant and extinct Crows, Ravens, Jays and Magpies worldwide and tag them with specific keywords making them available for researchers worldwide. The self-maintained project started in 2006 and today comprises 8000 articles, spanning almost 500 years. The CLD covers publications from 164 countries, written in 36 languages and published by 8026 authors in 1503 journals (plus books, theses and other publications). Forty-nine percent of all records are available online as full-text documents or deposited in the physical CLD archive. The CLD contains 442 original corvid descriptions. Here, we present a metadata assessment of articles recorded in the CLD including a gap analysis and prospects for future research. Database URL: http://www.corvids.de/cld PMID:26868053

Re-emergence of ZIKV has caused infections in more than 1.5 million people. The molecular mechanism and pathogenesis of ZIKV is not well explored due to unavailability of adequate model and lack of publically accessible resources to provide information of ZIKV-Human protein interactome map till today. This study made an attempt to curate the ZIKV-Human interaction proteins from published literatures and RNA-Seq data. 11 direct interaction, 12 associated genes are retrieved from literatures and 3742 Differentially Expressed Genes (DEGs) are obtained from RNA-Seq analysis. The genes have been analyzed to construct the ZIKV-Human Interactome Map. The importance of the study has been illustrated by the enrichment analysis and observed that direct interaction and associated genes are enriched in viral entry into host cell. Also, ZIKV infection modulates 32% signal and 27% immune system pathways. The integrated database, ZikaBase has been developed to help the virology research community and accessible at https://test5.bicpu.edu.in. Copyright © 2017 Elsevier Inc. All rights reserved.

To analyze the current research status of evidence-based nursing of burn in the mainland of China, in order to provide basis for the improvement of scientificity of burn nursing practice. Chinese scientific articles on evidence-based nursing of burn in the mainland of China published from January 1997 to December 2015 were retrieved from Chinese Biology Medicine disc, Chinese Journals Full-text Database, Wanfang Database, and VIP Database. From the results retrieved, date with regard to publication year, region of affiliation of the first author, journal distribution, literature type, literature quality assessment, topic of evidence-based research, fund program support, implementation of evidence-based practice steps, and language and quantity of reference. Data were processed with Microsoft Excel software. A total of 50 articles conforming to the criteria were retrieved. (1) Articles about evidence-based nursing of burn arose in 2004. Compared with that in the previous year, there was no obvious increase in the number of relevant articles in each year from 2004 to 2011. The number of literature in 2012 was obviously increased than that in each year from 2004 to 2011, while the number of literature in each year from 2012 to 2015 was not obviously increased compared with that in the previous year. (2) The regions of affiliation of the first author were distributed in 13 provinces, 3 minority autonomous regions, and 3 municipalities, with the largest distribution in East China, and Northwest China and Southwest China in the follow. (3) The articles were published in 32 domestic journals, with 9 (28.12%) nursing journals, 5 (15.62%) burn medical related journals, and 18 (56.25%) other journals. Twenty (40%) articles were published in Source Journal for Chinese Scientific and Technical Papers. (4) Regarding the literature type, 31 (62%) articles dealt with clinical experiences, 17 (34%) articles dealt with scientific research, and 2 (4%) articles dealt with case report. (5) There were 21 quantitative study articles and 29 narrative study articles, all with low quality. (6) The topics of evidence-based research in these articles were mainly burn rehabilitation, burn nursing technology, pediatric burn, inhalation injury and airway management, and complications of burn injury. Only one study was supported by fund program. (7) Only one article described complete evidence-based practice steps. (8) The literature cited 57 English articles as references, with an average of 1.14, and 316 Chinese articles, with an average of 6.32. The concept of evidence-based nursing of burn has been initially formed in the mainland of China. The number of relevant articles is on the rise, but the quality needs to be further improved. There is an urgent need to improve nurses' understanding of evidence-based nursing and their command of the method of evidence-based practice through on-job training, so as to improve the scientificity and effectiveness of burn nursing.

DMTB: the magnetotactic bacteria database

NASA Astrophysics Data System (ADS)

Pan, Y.; Lin, W.

2012-12-01

Magnetotactic bacteria (MTB) are of interest in biogeomagnetism, rock magnetism, microbiology, biomineralization, and advanced magnetic materials because of their ability to synthesize highly ordered intracellular nano-sized magnetic minerals, magnetite or greigite. Great strides for MTB studies have been made in the past few decades. More than 600 articles concerning MTB have been published. These rapidly growing data are stimulating cross disciplinary studies in such field as biogeomagnetism. We have compiled the first online database for MTB, i.e., Database of Magnestotactic Bacteria (DMTB, http://database.biomnsl.com). It contains useful information of 16S rRNA gene sequences, oligonucleotides, and magnetic properties of MTB, and corresponding ecological metadata of sampling sites. The 16S rRNA gene sequences are collected from the GenBank database, while all other data are collected from the scientific literature. Rock magnetic properties for both uncultivated and cultivated MTB species are also included. In the DMTB database, data are accessible through four main interfaces: Site Sort, Phylo Sort, Oligonucleotides, and Magnetic Properties. References in each entry serve as links to specific pages within public databases. The online comprehensive DMTB will provide a very useful data resource for researchers from various disciplines, e.g., microbiology, rock magnetism and paleomagnetism, biogeomagnetism, magnetic material sciences and others.

Cervical Spine Involvement in Mild Traumatic Brain Injury: A Review

PubMed Central

Morin, Michael; Langevin, Pierre

2016-01-01

Background. There is a lack of scientific evidence in the literature on the involvement of the cervical spine in mTBI; however, its involvement is clinically accepted. Objective. This paper reviews evidence for the involvement of the cervical spine in mTBI symptoms, the mechanisms of injury, and the efficacy of therapy for cervical spine with concussion-related symptoms. Methods. A keyword search was conducted on PubMed, ICL, SportDiscus, PEDro, CINAHL, and Cochrane Library databases for articles published since 1990. The reference lists of articles meeting the criteria (original data articles, literature reviews, and clinical guidelines) were also searched in the same databases. Results. 4,854 records were screened and 43 articles were retained. Those articles were used to describe different subjects such as mTBI's signs and symptoms, mechanisms of injury, and treatments of the cervical spine. Conclusions. The hypothesis of cervical spine involvement in post-mTBI symptoms and in PCS (postconcussion syndrome) is supported by increasing evidence and is widely accepted clinically. For the management and treatment of mTBIs, few articles were available in the literature, and relevant studies showed interesting results about manual therapy and exercises as efficient tools for health care practitioners.

Our group developed two biological applications, Biblio-MetReS and Homol-MetReS, accessing the same database of organisms with annotated genes. Biblio-MetReS is a data-mining application that facilitates the reconstruction of molecular networks based on automated text-mining analysis of published scientific literature. Homol-MetReS allows functional (re)annotation of proteomes, to properly identify both the individual proteins involved in the process(es) of interest and their function. It also enables the sets of proteins involved in the process(es) in different organisms to be compared directly. The efficiency of these biological applications is directly related to the design of the shared database. We classified and analyzed the different kinds of access to the database. Based on this study, we tried to adjust and tune the configurable parameters of the database server to reach the best performance of the communication data link to/from the database system. Different database technologies were analyzed. We started the study with a public relational SQL database, MySQL. Then, the same database was implemented by a MapReduce-based database named HBase. The results indicated that the standard configuration of MySQL gives an acceptable performance for low or medium size databases. Nevertheless, tuning database parameters can greatly improve the performance and lead to very competitive runtimes. PMID:25202745

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

2012-03-15

In the present paper we have updated the G6PD mutations database, including all the last discovered G6PD genetic variants. We underline that the last database has been published by Vulliamy et al. [1] who analytically reported 140 G6PD mutations: along with Vulliamy's database, there are two main sites, such as http://202.120.189.88/mutdb/ and www.LOVD.nl/MR, where almost all G6PD mutations can be found. Compared to the previous mutation reports, in our paper we have included for each mutation some additional information, such as: the secondary structure and the enzyme 3D position involving by mutation, the creation or abolition of a restriction site (with the enzyme involved) and the conservation score associated with each amino acid position. The mutations reported in the present tab have been divided according to the gene's region involved (coding and non-coding) and mutations affecting the coding region in: single, multiple (at least with two bases involved) and deletion. We underline that for the listed mutations, reported in italic, literature doesn't provide all the biochemical or bio-molecular information or the research data. Finally, for the "old" mutations, we tried to verify features previously reported and, when subsequently modified, we updated the specific information using the latest literature data.

To evaluate the quantity and quality of published literature conducted by pharmacy practice faculty members in US colleges and schools of pharmacy for the years 2001-2003. The Web of Science bibliographic database was used to identify publication citations for the years 2001-2003, which were then evaluated in a number of different ways. Faculty members were identified using American Association of Colleges of Pharmacy rosters for the 2000-2001, 2001-2002, and 2002-2003 academic years. Two thousand three hundred seventy-four pharmacy practice faculty members generated 1,896 publications in Web of Science searchable journals. A small number of faculty members (2.1%) were responsible for a large proportion of publications (30.6%), and only 4.9% of faculty members published 2 or more publications in these journals per year. The average impact factor for the top 200 publications was 7.6. Pharmacy practice faculty members contributed substantially to the biomedical literature and their work has had an important impact. A substantial portion of this work has come from a small subset of faculty members.

The IEDB, www.iedb.org, contains information on immune epitopes—the molecular targets of adaptive immune responses—curated from the published literature and submitted by National Institutes of Health funded epitope discovery efforts. From 2004 to 2012 the IEDB curation of journal articles published since 1960 has caught up to the present day, with >95% of relevant published literature manually curated amounting to more than 15 000 journal articles and more than 704 000 experiments to date. The revised curation target since 2012 has been to make recent research findings quickly available in the IEDB and thereby ensure that it continues to be an up-to-date resource. Having gathered a comprehensive dataset in the IEDB, a complete redesign of the query and reporting interface has been performed in the IEDB 3.0 release to improve how end users can access this information in an intuitive and biologically accurate manner. We here present this most recent release of the IEDB and describe the user testing procedures as well as the use of external ontologies that have enabled it. PMID:25300482

Publication proportions for registered breast cancer trials: before and following the introduction of the ClinicalTrials.gov results database.

PubMed

Asiimwe, Innocent Gerald; Rumona, Dickson

2016-01-01

To limit selective and incomplete publication of the results of clinical trials, registries including ClinicalTrials.gov were introduced. The ClinicalTrials.gov registry added a results database in 2008 to enable researchers to post the results of their trials as stipulated by the Food and Drug Administration Amendment Act of 2007. This study aimed to determine the direction and magnitude of any change in publication proportions of registered breast cancer trials that occurred since the inception of the ClinicalTrials.gov results database. A cross-sectional study design was employed using ClinicalTrials.gov, a publicly available registry/results database as the primary data source. Registry contents under the subcategories 'Breast Neoplasms' and 'Breast Neoplasms, Male' were downloaded on 1 August 2015. A literature search for included trials was afterwards conducted using MEDLINE and DISCOVER databases to determine publication status of the registered breast cancer trials. Nearly half (168/340) of the listed trials had been published, with a median time to publication of 24 months (Q1 = 14 months, Q3 = 42 months). Only 86 trials were published within 24 months of completion. There was no significant increase in publication proportions of trials that were completed before the introduction of the results database compared to those completed after (OR = 1.00, 95 % CI = .61 to 1.63; adjusted OR = 0.84, 95 % CI = .51 to 1.39). Characteristics associated with publication included trial type (observational versus interventional adjusted OR = .28, 95 % CI = .10 to .74) and completion/termination status (terminated versus completed adjusted OR = .22, 95 % CI = .09 to .51). Less than a half of breast cancer trials registered in ClinicalTrials.gov are published in peer-reviewed journals.

More than 7000 papers related to "protein refolding" have been published to date, with approximately 300 reports each year during the last decade. Whilst some of these papers provide experimental protocols for protein refolding, a survey in the structural life science communities showed a necessity for a comprehensive database for refolding techniques. We therefore have developed a new resource - "REFOLDdb" that collects refolding techniques into a single, searchable repository to help researchers develop refolding protocols for proteins of interest. We based our resource on the existing REFOLD database, which has not been updated since 2009. We redesigned the data format to be more concise, allowing consistent representations among data entries compared with the original REFOLD database. The remodeled data architecture enhances the search efficiency and improves the sustainability of the database. After an exhaustive literature search we added experimental refolding protocols from reports published 2009 to early 2017. In addition to this new data, we fully converted and integrated existing REFOLD data into our new resource. REFOLDdb contains 1877 entries as of March 17 th , 2017, and is freely available at http://p4d-info.nig.ac.jp/refolddb/ . REFOLDdb is a unique database for the life sciences research community, providing annotated information for designing new refolding protocols and customizing existing methodologies. We envisage that this resource will find wide utility across broad disciplines that rely on the production of pure, active, recombinant proteins. Furthermore, the database also provides a useful overview of the recent trends and statistics in refolding technology development.

Quantifying Data Quality for Clinical Trials Using Electronic Data Capture

PubMed Central

Nahm, Meredith L.; Pieper, Carl F.; Cunningham, Maureen M.

2008-01-01

Background Historically, only partial assessments of data quality have been performed in clinical trials, for which the most common method of measuring database error rates has been to compare the case report form (CRF) to database entries and count discrepancies. Importantly, errors arising from medical record abstraction and transcription are rarely evaluated as part of such quality assessments. Electronic Data Capture (EDC) technology has had a further impact, as paper CRFs typically leveraged for quality measurement are not used in EDC processes. Methods and Principal Findings The National Institute on Drug Abuse Treatment Clinical Trials Network has developed, implemented, and evaluated methodology for holistically assessing data quality on EDC trials. We characterize the average source-to-database error rate (14.3 errors per 10,000 fields) for the first year of use of the new evaluation method. This error rate was significantly lower than the average of published error rates for source-to-database audits, and was similar to CRF-to-database error rates reported in the published literature. We attribute this largely to an absence of medical record abstraction on the trials we examined, and to an outpatient setting characterized by less acute patient conditions. Conclusions Historically, medical record abstraction is the most significant source of error by an order of magnitude, and should be measured and managed during the course of clinical trials. Source-to-database error rates are highly dependent on the amount of structured data collection in the clinical setting and on the complexity of the medical record, dependencies that should be considered when developing data quality benchmarks.

Hashem, Kawther M; He, Feng J; MacGregor, Graham A

2016-01-01

Introduction Obesity, type 2 diabetes and dental caries are all major public health problems in the UK, with significant costs to the healthcare service. We aim to conduct a systematic review to summarise the evidence on the effectiveness of product reformulation measures to reduce the sugar content of food and drink on the population's sugar consumption and health. Methods and analysis Electronic database will be systematically searched using a combination of terms, tailored to optimise sensitivity, specificity, and the syntax and functionality of each database. The databases searched will include the Cochrane Library, EMBASE, MEDLINE (Ovid) and Scopus. The bibliographies of those papers that match inclusion criteria will be searched by hand to identify any further, relevant references, which will be subject to the same screening and selection process. The database search results will be supplemented by hand searches. In addition to the peer-reviewed literature, a number of grey literature searches will be undertaken using the broad search terms ‘sugar’ and ‘food’ or ‘drink’ and ‘reduction’, these searches will include key government and organisation websites as well as general searches in Google. The selection of the studies, data collection and quality appraisal will be performed independently by 2 reviewers. Data will be initially analysed through a narrative synthesis method. If a subset of data we analyse appears comparable, we will investigate the possibility of performing a meta-analysis. Ethics and dissemination Ethics approval will not be required as this is a protocol for a systematic review. The findings will be disseminated widely through conference presentations and published in a peer-reviewed journal. PROSPERO registration number CRD42016034022. PMID:27288379

Development and application of biosorption database for the control of heavy metals in waste and wastewaters

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

Min, J.H.; Hering, J.G.

1996-11-01

The rapid removal and high sorption capacity for metals as well as the cost-effectiveness of biosorption makes it a promising alternative for remediation or treatment of metals in the aquatic environment. Depending on the type of biomass, the sorption capacity may vary significantly for different metals, and thus it is important to evaluate the sorption characteristics of biomass for optimal removal of metals from the wastewaters. The objective of developing a biosorption database was to use available literature data for preliminary evaluation of potential significance of biosorption. The database was developed by collecting biosorption data sets from the published literature,more » extracting raw data from the papers, and re-analyzing the data with a consistent model. The re-analysis was crucial in developing the database because of the inconsistency in sorption models and units used by various investigators. The raw data from the literature were obtained using a digitizer and fitted with a same isotherm model with consistent units, which enabled quantitative comparison between data sets under similar conditions from different sources by comparing the isotherm constants. Metal sorption by biomass can be influenced by various environmental conditions such as pH, temperature, the characteristics or composition of the solution, and the presence of other complexing ligands in the solution. Biosorption of a specific metal by a specific species or type of biomass under different conditions can be compared to evaluate the effect of each parameter and to assess the possibility of lumping constants for a general case. The general sorption parameters for similar types of biomass under similar conditions can be used in preliminary assessment of metal/biomass combination for the optimal removal or stabilization of heavy metals.« less

What is lost when searching only one literature database for articles relevant to injury prevention and safety promotion?

PubMed

Lawrence, D W

2008-12-01

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.

2014-04-01

The Pacific Island countries and territories (PICTs) are reported to be free of the most serious infectious livestock diseases which are prevalent in other parts of the globe, such as Highly Pathogenic Avian Influenza, Foot and Mouth Disease or Rabies. Yet there is a lack of scientifically based evidence to confirm this animal health status. This paper reviews what has been published on diseases of domestic animals in the Pacific Islands region with a particular focus on data from the last 20 years (1992-2012). Relevant published papers were identified by a computerized literature search of two electronic databases (PubMed and Web of Knowledge). The latest reports on the animal health situation submitted by the PICTs to the World Organisation for Animal Health (OIE) were accessed on the World Animal Health Information Database (WAHID) interface and included in this review. Additionally, paper searches of resources were undertaken at the library of the Secretariat of the Pacific Community (SPC) in Fiji to retrieve any relevant grey literature for this review. The study eligibility criteria included qualitative or quantitative information on any disease (bacterial, viral, parasitic and other health disorders) affecting domestic terrestrial animals (mammals, reptiles, birds and bees) in any of the 22 PICTs members of the SPC. A total of 158 eligible references were retrieved of which only 77 (48.7%) were published since 1992 and analysed in more details. One hundred and one diseases and pathogens were reported on for bee, bird, carabao, cat, cattle, crocodile, deer, dog, donkey, goat, horse, pig, pigeon, poultry and sheep in the Oceania region and in 17 PICTs in particular. The paper gives information about known animal diseases, their reported prevalence and diseases not reported within the Pacific Islands region. The study found retrieved literature on animal diseases in PICTs was scarce and no longer up to date. There is a need to improve the published knowledge on the current animal disease status in the region. Copyright © 2013 Elsevier B.V. All rights reserved.

Vaughn, Natalie H.; Stepanyan, Hayk; Gallo, Robert A.; Dhawan, Aman

2017-01-01

Background: Tendon injury such as tendinopathy or rupture is common and has multiple etiologies, including both intrinsic and extrinsic factors. The genetic influence on susceptibility to tendon injury is not well understood. Purpose: To analyze the published literature regarding genetic factors associated with tendon injury. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic review of published literature was performed in concordance with the Preferred Reporting Items of Systematic Reviews and Meta-analysis (PRISMA) guidelines to identify current evidence for genetic predisposition to tendon injury. PubMed, Ovid, and ScienceDirect databases were searched. Studies were included for review if they specifically addressed genetic factors and tendon injuries in humans. Reviews, animal studies, or studies evaluating the influence of posttranscription factors and modifications (eg, proteins) were excluded. Results: Overall, 460 studies were available for initial review. After application of inclusion and exclusion criteria, 11 articles were ultimately included for qualitative synthesis. Upon screening of references of these 11 articles, an additional 15 studies were included in the final review, for a total of 26 studies. The genetic factors with the strongest evidence of association with tendon injury were those involving type V collagen A1, tenascin-C, matrix metalloproteinase–3, and estrogen-related receptor beta. Conclusion: The published literature is limited to relatively homogenous populations, with only level 3 and level 4 data. Additional research is needed to make further conclusions about the genetic factors involved in tendon injury. PMID:28856171

A Review on Recent Patents and Applications of Inorganic Material Binding Peptides.

2017-01-01

Although the popularity of using combinatorial display techniques for recognising unique peptides having high affinity for inorganic (nano) particles has grown rapidly, there are no systematic reviews showcasing current developments or patents on binding peptides specific to these materials. In this review, we summarize and discuss recent progress in patents on material binding peptides specifically exploring inorganic nano surfaces such as metals, metal oxides, minerals, carbonbased materials, polymer based materials, magnetic materials and semiconductors. We consider both the peptide display strategies used and the exploitation of the identified peptides in the generation of advanced nanomaterials. In order to get a clear picture on the number of patents and literature present to date relevant to inorganic material binding biomolecules and their applications, a thorough online search was conducted using national and worldwide databases. The literature search include standard bibliographic databases while patents included EPO Espacenet, WIPO patent scope, USPTO, Google patent search, Patent lens, etc. along with commercial databases such as Derwent and Patbase. Both English and American spellings were included in the searches. The initial number of patents found related to material binders were 981. After reading and excluding irrelevant patents such as organic binding peptides, works published before 2001, repeated patents, documents not in English etc., 51 highly relevant patents published from 2001 onwards were selected and analysed. These patents were further separated into six categories based on their target inorganic material and combinatorial library used. They include relevant patents on metal, metal oxide or combination binding peptides (19), magnetic and semiconductor binding peptides (8), carbon based (3), mineral (5), polymer (8) and other binders (9). Further, how these material specific binders have been used to synthesize simple to complex bio- or nano-materials, mediate the controlled biomineralization process, direct self-assembly and nanofabrication of ordered structures, facilitate the immobilization of functional biomolecules and construct inorganic-inorganic or organic-inorganic nano hybrids are concisely described. From analysis of recent literature and patents, we clearly show that biomimetic material binders are in the vanguard of new design approaches for novel nanomaterials with improved/ controlled physical and chemical properties that have no adverse effect on the structural or functional activities of the nanomaterials themselves.

ClassLess: A Comprehensive Database of Young Stellar Objects

NASA Astrophysics Data System (ADS)

Hillenbrand, Lynne A.; baliber, nairn

2015-08-01

We have designed and constructed a database intended to house catalog and literature-published measurements of Young Stellar Objects (YSOs) within ~1 kpc of the Sun. ClassLess, so called because it includes YSOs in all stages of evolution, is a relational database in which user interaction is conducted via HTML web browsers, queries are performed in scientific language, and all data are linked to the sources of publication. Each star is associated with a cluster (or clusters), and both spatially resolved and unresolved measurements are stored, allowing proper use of data from multiple star systems. With this fully searchable tool, myriad ground- and space-based instruments and surveys across wavelength regimes can be exploited. In addition to primary measurements, the database self consistently calculates and serves higher level data products such as extinction, luminosity, and mass. As a result, searches for young stars with specific physical characteristics can be completed with just a few mouse clicks. We are in the database population phase now, and are eager to engage with interested experts worldwide on local galactic star formation and young stellar populations.

Sequence annotations, functional and structural data on snake venom neurotoxins (svNTXs) are scattered across multiple databases and literature sources. Sequence annotations and structural data are available in the public molecular databases, while functional data are almost exclusively available in the published articles. There is a need for a specialized svNTXs database that contains NTX entries, which are organized, well annotated and classified in a systematic manner. We have systematically analyzed svNTXs and classified them using structure-function groups based on their structural, functional and phylogenetic properties. Using conserved motifs in each phylogenetic group, we built an intelligent module for the prediction of structural and functional properties of unknown NTXs. We also developed an annotation tool to aid the functional prediction of newly identified NTXs as an additional resource for the venom research community. We created a searchable online database of NTX proteins sequences (http://research.i2r.a-star.edu.sg/Templar/DB/snake_neurotoxin). This database can also be found under Swiss-Prot Toxin Annotation Project website (http://www.expasy.org/sprot/).

A guide to writing case reports for the Journal of Medical Case Reports and BioMed Central Research Notes

PubMed Central

2013-01-01

Case reports are a time-honored, important, integral, and accepted part of the medical literature. Both the Journal of Medical Case Reports and the Case Report section of BioMed Central Research Notes are committed to case report publication, and each have different criteria. Journal of Medical Case Reports was the world’s first international, PubMed-listed medical journal devoted to publishing case reports from all clinical disciplines and was launched in 2007. The Case Report section of BioMed Central Research Notes was created and began publishing case reports in 2012. Between the two of them, thousands of peer-reviewed case reports have now been published with a worldwide audience. Authors now also have Cases Database, a continually updated, freely accessible database of thousands of medical case reports from multiple publishers. This informal editorial outlines the process and mechanics of how and when to write a case report, and provides a brief look into the editorial process behind each of these complementary journals along with the author’s anecdotes in the hope of inspiring all authors (both novice and experienced) to write and continue writing case reports of all specialties. Useful hyperlinks are embedded throughout for easy and quick reference to style guidelines for both journals. PMID:24283456

Tea is one of the most consumed beverages worldwide. The healthy effects of tea are attributed to a wealthy of different chemical components from tea. Thousands of studies on the chemical constituents of tea had been reported. However, data from these individual reports have not been collected into a single database. The lack of a curated database of related information limits research in this field, and thus a cohesive database system should necessarily be constructed for data deposit and further application. The Tea Metabolome database (TMDB), a manually curated and web-accessible database, was developed to provide detailed, searchable descriptions of small molecular compounds found in Camellia spp. esp. in the plant Camellia sinensis and compounds in its manufactured products (different kinds of tea infusion). TMDB is currently the most complete and comprehensive curated collection of tea compounds data in the world. It contains records for more than 1393 constituents found in tea with information gathered from 364 published books, journal articles, and electronic databases. It also contains experimental 1H NMR and 13C NMR data collected from the purified reference compounds or collected from other database resources such as HMDB. TMDB interface allows users to retrieve tea compounds entries by keyword search using compound name, formula, occurrence, and CAS register number. Each entry in the TMDB contains an average of 24 separate data fields including its original plant species, compound structure, formula, molecular weight, name, CAS registry number, compound types, compound uses including healthy benefits, reference literatures, NMR, MS data, and the corresponding ID from databases such as HMDB and Pubmed. Users can also contribute novel regulatory entries by using a web-based submission page. The TMDB database is freely accessible from the URL of http://pcsb.ahau.edu.cn:8080/TCDB/index.jsp. The TMDB is designed to address the broad needs of tea biochemists, natural products chemists, nutritionists, and members of tea related research community. The TMDB database provides a solid platform for collection, standardization, and searching of compounds information found in tea. As such this database will be a comprehensive repository for tea biochemistry and tea health research community.

To systematically review the literature on the effect of providing oral healthcare education to care home nurses on their oral healthcare knowledge and attitude and their oral hygiene care skills. A literature search was obtained for relevant articles on oral healthcare education of nurses in care homes, using five electronic retrieval systems and databases. The search was limited to human studies, articles published in English and articles published during the period January 1990 to December 2011. The methodological quality of an article was assessed on the basis of criteria published by the Cochrane Collaboration. For articles not meeting all methodological quality criteria, relevance criteria were used to determine how much scientific evidence could be assigned to the study findings. In accordance with the methodological quality criteria, two randomized controlled trials were included. Additionally, four studies were included after determining the scientific evidence of the study findings. The studies included revealed some scientific evidence and indications that an oral healthcare education programme for care home nurses may improve the nurses' oral healthcare knowledge and attitude. Any effect of oral healthcare education to care home nurses' oral hygiene care skills could not be determined. Oral healthcare education may have a positive effect on care home nurses' oral healthcare knowledge and attitude and on care home residents' oral hygiene, whereas any effect on care home nurses' oral hygiene care skills could not be found. © 2013 John Wiley & Sons A/S.

PubChem is an open archive consisting of a set of three primary public databases (BioAssay, Compound, and Substance). It contains information on a broad range of chemical entities, including small molecules, lipids, carbohydrates, and (chemically modified) amino acid and nucleic acid sequences (including siRNA and miRNA). Currently (as of Nov. 2015), PubChem contains more than 150 million depositor-provided chemical substance descriptions, 60 million unique chemical structures, and 225 million biological activity test results provided from over 1 million biological assay records. Many PubChem records (substances, compounds, and assays) include depositor-provided cross-references to scientific articles in PubMed. Some PubChem contributors provide bioactivity data extracted from scientific articles. Literature-derived bioactivity data complement high-throughput screening (HTS) data from the concluded NIH Molecular Libraries Program and other HTS projects. Some journals provide PubChem with information on chemicals that appear in their newly published articles, enabling concurrent publication of scientific articles in journals and associated data in public databases. In addition, PubChem links records to PubMed articles indexed with the Medical Subject Heading (MeSH) controlled vocabulary thesaurus. Literature information, both provided by depositors and derived from MeSH annotations, can be accessed using PubChem's web interfaces, enabling users to explore information available in literature related to PubChem records beyond typical web search results.

True aneurysm in autologous hemodialysis fistulae: definitions, classification and indications for treatment.

PubMed

Balaz, Peter; Björck, Martin

2015-01-01

Definition, etiology, classification and indication for treatment of the arteriovenous access (AVA) aneurysm are poorly described in medical literature. The objectives of the paper are to complete this information gap according to the extensive review of the literature. A literature search was performed of the articles published between April 1, 1967, and March 1, 2014. The databases searched included Medline and the Cochrane Database of Systematic Reviews. The eligibility criteria in this review studies the need to assess the association of aneurysms and pseudoaneurysms with autologous AVA. Aneurysms and pseudoaneurysms involving prosthetic AVA were not included in this literature review. From a total of 327 papers, 54 non-English papers, 40 case reports and 167 papers which did not meet the eligibility criteria were removed. The remaining 66 papers were reviewed. Based on the literature the indication for the treatment of an AVA aneurysm is its clinical presentation related to the patient's discomfort, bleeding prevention and inadequate access flow. A new classification system of AVA aneurysm, which divides it into the four types, was also suggested. AVA aneurysm is characterized by an enlargement of all three vessel layers with a diameter of more than 18 mm and can be presented in four types according to the presence of stenosis and/or thrombosis. The management of an AVA aneurysm depends on several factors including skin condition, clinical symptoms, ease of cannulation and access flow. The diameter of the AVA aneurysm as a solo parameter is not an indication for the treatment.

OBJECTIVE To analyze Brazilian literature on body image and the theoretical and methodological advances that have been made. METHODS A detailed review was undertaken of the Brazilian literature on body image, selecting published articles, dissertations and theses from the SciELO, SCOPUS, LILACS and PubMed databases and the CAPES thesis database. Google Scholar was also used. There was no start date for the search, which used the following search terms: “body image” AND “Brazil” AND “scale(s)”; “body image” AND “Brazil” AND “questionnaire(s)”; “body image” AND “Brazil” AND “instrument(s)”; “body image” limited to Brazil and “body image”. RESULTS The majority of measures available were intended to be used in college students, with half of them evaluating satisfaction/dissatisfaction with the body. Females and adolescents of both sexes were the most studied population. There has been a significant increase in the number of available instruments. Nevertheless, numerous published studies have used non-validated instruments, with much confusion in the use of the appropriate terms (e.g., perception, dissatisfaction, distortion). CONCLUSIONS Much more is needed to understand body image within the Brazilian population, especially in terms of evaluating different age groups and diversifying the components/dimensions assessed. However, interest in this theme is increasing, and important steps have been taken in a short space of time. PMID:24897056

Obstructive sleep apnea and oral language disorders.

Corrêa, Camila de Castro; Cavalheiro, Maria Gabriela; Maximino, Luciana Paula; Weber, Silke Anna Theresa

Children and adolescents with obstructive sleep apnea (OSA) may have consequences, such as daytime sleepiness and learning, memory, and attention disorders, that may interfere in oral language. To verify, based on the literature, whether OSA in children was correlated to oral language disorders. A literature review was carried out in the Lilacs, PubMed, Scopus, and Web of Science databases using the descriptors "Child Language" AND "Obstructive Sleep Apnea". Articles that did not discuss the topic and included children with other comorbidities rather than OSA were excluded. In total, no articles were found at Lilacs, 37 at PubMed, 47 at Scopus, and 38 at Web of Science databases. Based on the inclusion and exclusion criteria, six studies were selected, all published from 2004 to 2014. Four articles demonstrated an association between primary snoring/OSA and receptive language and four articles showed an association with expressive language. It is noteworthy that the articles used different tools and considered different levels of language. The late diagnosis and treatment of obstructive sleep apnea is associated with a delay in verbal skill acquisition. The professionals who work with children should be alert, as most of the phonetic sounds are acquired during ages 3-7 years, which is also the peak age for hypertrophy of the tonsils and childhood OSA.

Animal experiments have shown that after specific nerve traumatization, neuromuscular electrostimulation (NMES) can promote nerve regeneration and reduce synkinesia without negatively interfering with normal regeneration processes. NMES is used routinely in physical rehabilitation medicine. This systematic literature search in the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, the DAHTA database, the Health Technology Assessment Database and MEDLINE or PubMed considered studies on the use of NMES in otorhinolaryngology that have been published in German or English. The search identified 180 studies. These were evaluated and relevant studies were included in the further evaluation. In the fields of otorhinolaryngology and phoniatry/paediatric audiology, clinical studies investigating the effects of NMES on facial and laryngeal paresis, as well as dysphonia and dysphagia have been carried out. The evidence collected to date is encouraging; particularly for the treatment of certain forms of dysphagia and laryngeal paresis.

To address the need for a centralized root trait database, we are compiling the Fine-Root Ecology Database (FRED) from published literature and unpublished data. FRED Version 1 (FRED 1.0) currently houses more than 70,000 observations of root traits and their associated site, vegetation, edaphic, and climatic conditions from across the globe (see image below, which shows the more than 1000 distinct locations associated with observations in FRED 1.0). Data collection is ongoing and will continue for the foreseeable future. The more than 300 root traits currently housed in FRED 1.0 are described in detail here. FRED is focused on finemore » roots (less than 2 mm), as coarse roots are studied using different methodology, often at very different scales, and have different traits and trait interpretations.« less

Identifying complications of interventional procedures from UK routine healthcare databases: a systematic search for methods using clinical codes.

2014-11-28

Several authors have developed and applied methods to routine data sets to identify the nature and rate of complications following interventional procedures. But, to date, there has been no systematic search for such methods. The objective of this article was to find, classify and appraise published methods, based on analysis of clinical codes, which used routine healthcare databases in a United Kingdom setting to identify complications resulting from interventional procedures. A literature search strategy was developed to identify published studies that referred, in the title or abstract, to the name or acronym of a known routine healthcare database and to complications from procedures or devices. The following data sources were searched in February and March 2013: Cochrane Methods Register, Conference Proceedings Citation Index - Science, Econlit, EMBASE, Health Management Information Consortium, Health Technology Assessment database, MathSciNet, MEDLINE, MEDLINE in-process, OAIster, OpenGrey, Science Citation Index Expanded and ScienceDirect. Of the eligible papers, those which reported methods using clinical coding were classified and summarised in tabular form using the following headings: routine healthcare database; medical speciality; method for identifying complications; length of follow-up; method of recording comorbidity. The benefits and limitations of each approach were assessed. From 3688 papers identified from the literature search, 44 reported the use of clinical codes to identify complications, from which four distinct methods were identified: 1) searching the index admission for specified clinical codes, 2) searching a sequence of admissions for specified clinical codes, 3) searching for specified clinical codes for complications from procedures and devices within the International Classification of Diseases 10th revision (ICD-10) coding scheme which is the methodology recommended by NHS Classification Service, and 4) conducting manual clinical review of diagnostic and procedure codes. The four distinct methods identifying complication from codified data offer great potential in generating new evidence on the quality and safety of new procedures using routine data. However the most robust method, using the methodology recommended by the NHS Classification Service, was the least frequently used, highlighting that much valuable observational data is being ignored.

Literature-based gene curation and proposed genetic nomenclature for cryptococcus.

2014-07-01

Cryptococcus, a major cause of disseminated infections in immunocompromised patients, kills over 600,000 people per year worldwide. Genes involved in the virulence of the meningitis-causing fungus are being characterized at an increasing rate, and to date, at least 648 Cryptococcus gene names have been published. However, these data are scattered throughout the literature and are challenging to find. Furthermore, conflicts in locus identification exist, so that named genes have been subsequently published under new names or names associated with one locus have been used for another locus. To avoid these conflicts and to provide a central source of Cryptococcus gene information, we have collected all published Cryptococcus gene names from the scientific literature and associated them with standard Cryptococcus locus identifiers and have incorporated them into FungiDB (www.fungidb.org). FungiDB is a panfungal genome database that collects gene information and functional data and provides search tools for 61 species of fungi and oomycetes. We applied these published names to a manually curated ortholog set of all Cryptococcus species currently in FungiDB, including Cryptococcus neoformans var. neoformans strains JEC21 and B-3501A, C. neoformans var. grubii strain H99, and Cryptococcus gattii strains R265 and WM276, and have written brief descriptions of their functions. We also compiled a protocol for gene naming that summarizes guidelines proposed by members of the Cryptococcus research community. The centralization of genomic and literature-based information for Cryptococcus at FungiDB will help researchers communicate about genes of interest, such as those related to virulence, and will further facilitate research on the pathogen.

InverPep: A database of invertebrate antimicrobial peptides.

PubMed

Gómez, Esteban A; Giraldo, Paula; Orduz, Sergio

2017-03-01

The aim of this work was to construct InverPep, a database specialised in experimentally validated antimicrobial peptides (AMPs) from invertebrates. AMP data contained in InverPep were manually curated from other databases and the scientific literature. MySQL was integrated with the development platform Laravel; this framework allows to integrate programming in PHP with HTML and was used to design the InverPep web page's interface. InverPep contains 18 separated fields, including InverPep code, phylum and species source, peptide name, sequence, peptide length, secondary structure, molar mass, charge, isoelectric point, hydrophobicity, Boman index, aliphatic index and percentage of hydrophobic amino acids. CALCAMPI, an algorithm to calculate the physicochemical properties of multiple peptides simultaneously, was programmed in PERL language. To date, InverPep contains 702 experimentally validated AMPs from invertebrate species. All of the peptides contain information associated with their source, physicochemical properties, secondary structure, biological activity and links to external literature. Most AMPs in InverPep have a length between 10 and 50 amino acids, a positive charge, a Boman index between 0 and 2 kcal/mol, and 30-50% hydrophobic amino acids. InverPep includes 33 AMPs not reported in other databases. Besides, CALCAMPI and statistical analysis of InverPep data is presented. The InverPep database is available in English and Spanish. InverPep is a useful database to study invertebrate AMPs and its information could be used for the design of new peptides. The user-friendly interface of InverPep and its information can be freely accessed via a web-based browser at http://ciencias.medellin.unal.edu.co/gruposdeinvestigacion/prospeccionydisenobiomoleculas/InverPep/public/home_en.

Difficulties and challenges associated with literature searches in operating room management, complete with recommendations.

PubMed

Wachtel, Ruth E; Dexter, Franklin

2013-12-01

The purpose of this article is to teach operating room managers, financial analysts, and those with a limited knowledge of search engines, including PubMed, how to locate articles they need in the areas of operating room and anesthesia group management. Many physicians are unaware of current literature in their field and evidence-based practices. The most common source of information is colleagues. Many people making management decisions do not read published scientific articles. Databases such as PubMed are available to search for such articles. Other databases, such as citation indices and Google Scholar, can be used to uncover additional articles. Nevertheless, most people who do not know how to use these databases are reluctant to utilize help resources when they do not know how to accomplish a task. Most people are especially reluctant to use on-line help files. Help files and search databases are often difficult to use because they have been designed for users already familiar with the field. The help files and databases have specialized vocabularies unique to the application. MeSH terms in PubMed are not useful alternatives for operating room management, an important limitation, because MeSH is the default when search terms are entered in PubMed. Librarians or those trained in informatics can be valuable assets for searching unusual databases, but they must possess the domain knowledge relative to the subject they are searching. The search methods we review are especially important when the subject area (e.g., anesthesia group management) is so specific that only 1 or 2 articles address the topic of interest. The materials are presented broadly enough that the reader can extrapolate the findings to other areas of clinical and management issues in anesthesiology.

To investigate the meaning of comfort and to contextualise it within the framework of paediatric critical care. The concept of comfort is closely linked to care in all health contexts. However, in specific settings such as the paediatric critical care unit, it takes on particular importance. A literature review was conducted. A literature search was performed of articles in English and Spanish in international health science databases, from 1992-March 2017, applying the quality standards established by the PRISMA methodology and the Joanna Briggs Institute. A total of 1,203 publications were identified in the databases. Finally, 59 articles which met the inclusion criteria were entered in this literature review. Almost all were descriptive studies written in English and published in Europe. The concept of comfort was defined as the immediate condition of being strengthened through having the three types of needs (relief, ease and transcendence) addressed in the four contexts of experience (physical, psychospiritual, social and environmental). Only two valid and reliable tools for assessing comfort were found: the Comfort Scale and the Comfort Behavior Scale. Comfort is subjective and difficult to assess. It has four facets: physical, emotional, social and environmental. High levels of noise and light are the inputs that cause the most discomfort. Comfort is a holistic, universal concept and an important component of quality nursing care. © 2018 John Wiley & Sons Ltd.

Chaffey, Lisa Jane; de Leeuw, Evelyne Johanna Janet; Finnigan, Gerard Anthony

2012-01-01

Reflection and reflective practice is of increasing importance in medical education curricula. The aim of this review is to summarise the literature published around facilitating reflection in a medical course, and to answer the question : W0 hat is the current evidence regarding learning and development moments across the medical curriculum in developing students' reflective practice? A review of the literature was undertaken using defined databases and the search terms 'medical students', 'medical education', 'reflection', 'reflectFNx01' and 'medicine'. The search was limited to peer-reviewed published material in English and between the years 2001 and 2011, and included research, reviews and opinion pieces. Thirty-six relevant articles were found, identifying enhancing factors and barriers to effectively teaching reflective practice within medical curricula, relating to: The breadth of the meaning of reflection; facilitating reflection by medical educators; using written or web-based portfolios to facilitate reflection; and assessing the reflective work of students. A variety of reflective purposes was found in this literature review. Evidence indicates that, if students are unclear as to the purpose of reflection and do not see educators modelling reflective behaviours, they are likely to undervalue this important skill regardless of the associated learning and development opportunities embedded in the curriculum.

2006-11-01

There have been several reports of successful psychosocial interventions for children with selective mutism (SM), a disorder in which a child consistently fails to speak in one or more social settings (e.g., school) despite speaking normally in other settings (e.g., home). The present literature review was undertaken in order to provide an up-to-date summary and critique of the SM treatment literature published in the past fifteen years. PubMed, PsycINFO, and Web of Science databases were searched to identify SM treatment studies published in peer-reviewed journals between 1990 and 2005. A total of 23 studies were included in the present review. Of these, ten used a behavioral/cognitive behavioral approach, one used a behavioral language training approach, one used a family systems approach, five used a psychodynamic approach, and six used multimodal approaches to SM treatment. Although much of this literature is limited by methodological weaknesses, the existing research provides support for the use of behavioral and cognitive-behavioral interventions. Multimodal treatments also appear promising, but the essential components of these interventions have yet to be established. An outline of a cognitive-behavioral treatment package for a typical SM child is provided and the review concludes with suggestions for future research.

To systematically review the scientific production on the relationship between Attention Deficit Hyperactivity Disorder (ADHD) and Speech-language Pathology and to methodologically analyze the observational studies on the theme. Systematic review of the literature conducted at the databases Medical Literature Analysis and Retrieval System online (MEDLINE, USA), Literature of Latin America and the Caribbean Health Sciences (LILACS, Brazil) and Spanish Bibliographic Index of Health Sciences (IBECS, Spain) using the descriptors: "Language", "Language Development", "Attention Deficit Hyperactivity Disorder", "ADHD" and "Auditory Perception". Articles published between 2008 and 2013. Inclusion criteria: full articles published in national and international journals from 2008 to 2013. Exclusion criteria: articles not focused on the speech-language pathology alterations present in the attention deficit hyperactivity disorder. The articles were read in full and the data were extracted for characterization of methodology and content. The 23 articles found were separated according to two themes: Speech-language Pathology and Attention Deficit Hyperactivity Disorder. The study of the scientific production revealed that the alterations most commonly discussed were reading disorders and that there are few reports on the relationship between auditory processing and these disorders, as well as on the role of the speech-language pathologist in the evaluation and treatment of children with Attention Deficit Hyperactivity Disorder.

Sport prostheses are used by both upper- and lower-limb amputees while participating in sports and other physical activities. Although the number of these devices has increased over the past decade, no overview of the peer reviewed literature describing them has been published previously. Such an overview will allow specialists to choose appropriate prostheses based on available scientific evidence rather than on personal experience or preference. To provide an overview of the sport prostheses as they are described by the papers published in peer reviewed literature. Literature review. Four electronic databases were searched using free text and Medical Subject Headings (MESH) terms. Papers were included if they concerned a prosthesis or a prosthetic adaptation used in sports. Papers were excluded if they did not originate from peer reviewed sources, if they concerned prostheses for body parts other than the upper or lower limbs, if they concerned amputations distal to the wrist or ankle, or if they were written in a language other than English. Twenty-four papers were included in this study. The vast majority contained descriptive data and consisted of expert opinions and technical notes. Data concerning the energy efficiency, technical characteristics and special mechanical properties of prostheses or prosthetic adaptations for sports, other than running, are scarce.

Cardona, Genís; Sanz, Joan P

2014-09-01

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.

Systematic reviews of the studies published in the major medical data bases have not shown solid support for the use of ozone therapy. Unpublished or grey literature, including postgraduate theses, may solve this controversy. To review the postgraduate theses published in Egypt in order to assess the clinical safety and effectiveness of ozone therapy in specific medical conditions. The databases of the Egyptian Universities' Library Consortium and the databases of each university were searched for postgraduate theses that evaluated ozone therapy as an intervention for any disease or condition in any age group, compared with any or no other intervention and published before September 2010. A total of 28 quasi trials were included. The theses did not report any safety issues in terms of ozone therapy. With respect to its effectiveness, the studies suggested some benefits of ozone in the treatment of dental infection and recovery, musculoskeletal disorders, diabetes mellitus, chronic diseases, and obstetrics and gynaecology. However, the number of studies included was small and they were of limited quality. There is insufficient evidence to recommend the use of ozone in the treatment of dental infections, in facilitating faster dental recovery after extraction or implantation, in diabetes mellitus, musculoskeletal disorders, or obstetrics and gynaecology.

Background The safety and effectiveness of CAM interventions are of great relevance to pediatric health care providers. The objective of this study is to identify sources of reported randomized controlled trials (RCTs) in the field of pediatric complementary and alternative medicine (CAM). Methods Reports of RCTs were identified by searching Medline and 12 additional bibliographic databases and by reviewing the reference lists of previously identified pediatric CAM systematic reviews. Results We identified 908 reports of RCTs that included children under 18 and investigated a CAM therapy. Since 1965, there has been a steady growth in the number of these trials that are being published. The four journals that published the most reported RCTs are The American Journal of Clinical Nutrition, Pediatrics, Journal of Pediatrics, and Lancet. Medline, CAB Health, and Embase were the best database sources for identifying these studies; they indexed 93.2%, 58.4% and 42.2 % respectively of the journals publishing reports of pediatric CAM RCTs. Conclusions Those working or interested in the field of pediatric CAM should routinely search Medline, CAB Health and Embase for literature in the field. The four core journals identified above should be included in their collection. PMID:12589711

Ambiguous gene names in the biomedical literature are a barrier to accurate information extraction. To overcome this hurdle, we generated Ontology Fingerprints for selected genes that are relevant for personalized cancer therapy. These Ontology Fingerprints were used to evaluate the association between genes and biomedical literature to disambiguate gene names. We obtained 93.6% precision for the test gene set and 80.4% for the area under a receiver-operating characteristics curve for gene and article association. The core algorithm was implemented using a graphics processing unit-based MapReduce framework to handle big data and to improve performance. We conclude that Ontology Fingerprints can help disambiguate gene names mentioned in text and analyse the association between genes and articles.

Synthesis of data from published human genetic association studies is a critical step in the translation of human genome discoveries into health applications. Although genetic association studies account for a substantial proportion of the abstracts in PubMed, identifying them with standard queries is not always accurate or efficient. Further automating the literature-screening process can reduce the burden of a labor-intensive and time-consuming traditional literature search. The Support Vector Machine (SVM), a well-established machine learning technique, has been successful in classifying text, including biomedical literature. The GAPscreener, a free SVM-based software tool, can be used to assist in screening PubMed abstracts for human genetic association studies. The data source for this research was the HuGE Navigator, formerly known as the HuGE Pub Lit database. Weighted SVM feature selection based on a keyword list obtained by the two-way z score method demonstrated the best screening performance, achieving 97.5% recall, 98.3% specificity and 31.9% precision in performance testing. Compared with the traditional screening process based on a complex PubMed query, the SVM tool reduced by about 90% the number of abstracts requiring individual review by the database curator. The tool also ascertained 47 articles that were missed by the traditional literature screening process during the 4-week test period. We examined the literature on genetic associations with preterm birth as an example. Compared with the traditional, manual process, the GAPscreener both reduced effort and improved accuracy. GAPscreener is the first free SVM-based application available for screening the human genetic association literature in PubMed with high recall and specificity. The user-friendly graphical user interface makes this a practical, stand-alone application. The software can be downloaded at no charge.

UK PubMed Central (UKPMC) is a full-text article database that extends the functionality of the original PubMed Central (PMC) repository. The UKPMC project was launched as the first 'mirror' site to PMC, which in analogy to the International Nucleotide Sequence Database Collaboration, aims to provide international preservation of the open and free-access biomedical literature. UKPMC (http://ukpmc.ac.uk) has undergone considerable development since its inception in 2007 and now includes both a UKPMC and PubMed search, as well as access to other records such as Agricola, Patents and recent biomedical theses. UKPMC also differs from PubMed/PMC in that the full text and abstract information can be searched in an integrated manner from one input box. Furthermore, UKPMC contains 'Cited By' information as an alternative way to navigate the literature and has incorporated text-mining approaches to semantically enrich content and integrate it with related database resources. Finally, UKPMC also offers added-value services (UKPMC+) that enable grantees to deposit manuscripts, link papers to grants, publish online portfolios and view citation information on their papers. Here we describe UKPMC and clarify the relationship between PMC and UKPMC, providing historical context and future directions, 10 years on from when PMC was first launched.

The objective of this current study is to identify the growth and development of scholarly literature that specifically references the term 'school psychology' in the Science Citation Index from 1907 through 2014. Documents from Web of Science were accessed and analyzed through the use of scientometric analyses, including HistCite and Pajek software, resulting in the identification of 4,806 scholars who contributed 3,260 articles in 311 journals. Whereas the database included journals from around the world, most articles were published by authors in the United States and in 20 journals, including the Journal of School Psychology, Psychology in the Schools, School Psychology Review, School Psychology International, and School Psychology Quarterly. Analyses of the database from the past century revealed that 20 of the most prolific scholars contributed 14% of all articles. Contributions from faculty and students at University of Minnesota-Twin Cities, University of Nebraska-Lincoln, University of South Carolina, University of Wisconsin-Madison, and University of Texas-Austin represented 10% of all articles including the term school psychology in the Science Citation Index. Relationships among some of the most highly cited articles are also described. Collectively, the series of analyses reported herein contribute to our understanding of scholarship in school psychology. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Identifying, amongst millions of publications available in MEDLINE, those that are relevant to specific microRNAs (miRNAs) of interest based on keyword search faces major obstacles. References to miRNA names in the literature often deviate from standard nomenclature for various reasons, since even the official nomenclature evolves. For instance, a single miRNA name may identify two completely different molecules or two different names may refer to the same molecule. mirPub is a database with a powerful and intuitive interface, which facilitates searching for miRNA literature, addressing the aforementioned issues. To provide effective search services, mirPub applies text mining techniques on MEDLINE, integrates data from several curated databases and exploits data from its user community following a crowdsourcing approach. Other key features include an interactive visualization service that illustrates intuitively the evolution of miRNA data, tag clouds summarizing the relevance of publications to particular diseases, cell types or tissues and access to TarBase 6.0 data to oversee genes related to miRNA publications. mirPub is freely available at http://www.microrna.gr/mirpub/. vergoulis@imis.athena-innovation.gr or dalamag@imis.athena-innovation.gr Supplementary data are available at Bioinformatics online. © The Author 2014.

2016-01-01

The purpose of this study is to review the available literature that describes forces of the most commonly used chiropractic techniques for children. Review of the English-language literature using search terms Chiropract* and technique, protocol, or approach in databases PubMed, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine, and Index to Chiropractic Literature and direct contact with authors of articles and book chapters. Eleven articles that discussed the 7 most commonly used pediatric chiropractic techniques and the forces applied were identified. Chiropractic techniques reviewed described forces that were modified based on the age of the patient. Force data for mechanically assisted devices were varied, with the minimum force settings for some devices outside the age-specific safe range recommended in the literature when not modified in some way. This review found that technique selection and application by chiropractors treating infants and young children are typically modified in force and speed to suit the age and development of the child.

To establish how common and impactful nursing and healthcare ageism is and whether proven interventions or prevention methods exist. Ageism has been a concern since 1969 when it was first introduced as a concept for social reform. As ageism has been linked to lower quality health services and reduced health care access, it is imperative that healthcare and nursing ageism is prevented or identified and reduced or eliminated. A qualitative narrative review of published research literature reviews using a scoping design to map all published reviews was undertaken. The EBSCO Discovery Service (providing access to articles in 271 databases, including MEDLINE and CINAHL) and Directory of Open Access Journals (providing access to over 9,000 open access journals) were used to find review articles. Using predetermined inclusion and exclusion criteria, and limited by English language and peer-review publications, 12 eligible reviews were identified and information from them was systematically identified, assessed and synthesised. The 12 reviews did not provide clear and convincing information to determine how common and impactful nursing or healthcare ageism is, nor what can best be done to prevent or address it. Although each review had value since research literature was collected and discussed on nursing or healthcare ageism, the array of literature search and analysis methods, and diversity in conclusions reached about the evidence is highly problematic. Research literature reviews offering a more balanced perspective and demonstrating greater care in finding and using quality evidence are needed. At this point in time, there is no clear understanding of how widespread and impactful nursing or healthcare ageism is, and what can best be done to prevent or address it. Nurses need to be aware that ageism may be common and impactful, and guard against it. © 2017 John Wiley & Sons Ltd.

The knowledge of reporting compliance of systematic reviews with PRISMA guidelines may assist in improving the quality of secondary research in brain AVM management and subsequently application to patient population and clinical practice. This may allow researchers and clinicians to be equipped to appraise existing literatures based on known deficit to look for or expect. The objective of this study was to assess the compliance of systematic reviews and meta-analysis in the management of brain AVM. Systematic reviews and meta-analyses articles published in medical journals between 1st of May 2011 and 30th April 2016 (five-year period) were examined. Exclusion criteria were articles that were not systematic reviews and not meta-analyses, narrative literature reviews, historical literature reviews, animal studies, unpublished articles, commentaries and letter to the editor. Electronic database search performed through Medline PubMed on 20th September 2016. This systematic review examined seven systematic review articles on intracranial arteriovenous malformation compliance with PRISMA statement guidelines. The mean percentage of applicable PRISMA items across all studies was 74% (range 67-93%). Protocol registration and declaration, risk of bias and funding sources were the most poorly reported of the PRISMA items (14% each). A significant variance in the total percentages was evident between studies (67-93%). Systematic review reporting in medical literature is excessively variable and overall poor. As these papers are being published with increasing frequency, need to fully adhere to PRISMA statement guide for systematic review to ensure high-quality publications. Complete reporting of PRISMA items within systematic reviews in cerebral arteriovenous malformation enhance quality assessment, robust critical appraisal, better judgement and ultimately sound application to practice thereby improving research standards and patients care.

A Comprehensive Survey of Retracted Articles from the Scholarly Literature

PubMed Central

Grieneisen, Michael L.; Zhang, Minghua

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. Articles and editorials discussing retractions, or their relation to research integrity, should always consider individual cases in these broad contexts. However, better mechanisms are still needed for raising researchers’ awareness of the retracted literature in their field. PMID:23115617

Watwood, Carol L.

2016-01-01

Objective The purpose of this study was to identify core journals and other types of literature cited in four major pediatric nursing journals and to characterize coverage of these resources in major bibliographic databases. The study was part of the “Mapping the Literature of Nursing Project” of the Medical Library Association's Nursing and Allied Health Resource Section. It updates a similar analysis published in 2006 and determines whether citation patterns have changed over time. Methods Cited references from articles published in 4 pediatric nursing journals between 2011 and 2013 were collected. Cited journal titles were ranked according to number of times cited and analyzed according to Bradford's Law of Scattering and the 80/20 rule to identify the most frequently cited journals. Five databases were surveyed to assess the coverage of the most-often-cited journals. The most frequently cited non-journal sources were also identified. Results Journals were the most frequently cited sources, followed by books, government documents, Internet resources, and miscellaneous resources. Most cited sources were cited within ten years of their publication, which was particularly true for government documents and Internet resources. Scopus had complete coverage of the most frequently cited journals, whereas PubMed had nearly complete coverage. Conclusions Compared with the 2006 study, the list of top-cited journals referenced by pediatric nursing researchers has remained relatively stable, but the number of cited journal titles has increased. Book citations have declined, and Internet and government document references have increased. These findings suggest that librarians should retain subscriptions to frequently cited journal titles, provide efficient document delivery of articles from infrequently used journals, de-emphasize but not eliminate books, and connect patrons with useful open-access Internet resources.

The Effect of Calcium Sodium Phosphosilicate on Dentin Hypersensitivity: A Systematic Review and Meta-Analysis

PubMed Central

Chen, Bin; Mei, Li; Yao, Liang; Tian, Jinhui; Li, Huang

2015-01-01

Objective To investigate the effect of calcium sodium phosphosilicate (CSPS) in treating dentin hypersensitivity (DH) and to compare this effect to that of a negative (placebo) control. Materials and Methods Several databases, including Medline, EMBASE, Web of Science, The Cochrane Library, and the Chinese Biomedical Literature Database, were searched to identify relevant articles published through January 2015; grey literature (i.e., academic literature that is not formally published) was also searched. Two authors performed data extraction independently and jointly using data collection forms. The primary outcome was the DH pain response to routine activities or to thermal, tactile, evaporative, or electrical stimuli, and the secondary outcome was the side effects of CSPS use. Each study was evaluated using the Cochrane Collaboration tool for assessing risk bias. Meta-analysis of studies with the same participant demographics, interventions, controls, assessment methods and follow-up periods was performed. The Grading of Recommendations Assessment Development and Evaluation System was used to assess the quality of the evidence and the risk of bias across studies. Results Meta-analysis demonstrated that toothpaste containing 5% CSPS was more effective than the negative control at relieving dentin sensitivity, with the level of evidence classified as “moderate”. In addition, prophylaxis paste containing 15% calcium sodium phosphosilicate was favored over the negative control at reducing post-periodontal therapy hypersensitivity, with the level of evidence categorized as “low”. Only two studies reported side effects of CSPS use. Conclusions The majority of studies found that calcium sodium phosphosilicate was more effective than the negative control at alleviating DH. Because strong evidence is scarce, high-quality, well-designed clinical trials are required in the future before definitive recommendations can be made. PMID:26544035

Does intravenous contrast-enhanced computed tomography cause acute kidney injury? Protocol of a systematic review of the evidence

PubMed Central

2014-01-01

Background Contrast-induced acute kidney injury is a common cause of iatrogenic acute kidney injury (AKI). Most of the published estimates of AKI after contrast use originate from the cardiac catheterization literature despite contrast-enhanced computed tomography (CT) scans being the more common setting for contrast use. This systematic review aims to summarize the current evidence about (1)the risk of AKI following intravenous (IV) contrast-enhanced CT scans and(2) the risk of clinical outcomes (i.e. death, hospitalization and need for renal replacement therapy) due to IV contrast-enhanced CT scans. Methods/Design A systematic literature search for published studies will be performed using MEDLINE, EMBASE and The COCHRANE Library databases. Unpublished studies will be identified by searching through grey literature. No language restriction will be applied. The review will consider all studies that have examined the association between IV contrast media and AKI. To be selected, the study should include two arms: one group of exposed patients who received IV contrast material before CT scans and one group of unexposed group who did not receive contrast material before CT scans. Two authors will independently screen titles and abstracts obtained from electronic databases, extract data and will assess the quality of the studies selected using the Cochrane's ‘Risk of Bias’ assessment tool for randomized trials and the Newcastle-Ottawa Scale for observational studies. A random-effects meta-analysis will be performed if there is no remarkable heterogeneity between studies. Discussion This systematic review will provide synthesis of current evidence around the effect of IV contrast material on AKI and other clinical outcomes. Results will be helpful for making evidence-based recommendations and guidelines for clinical and radiologic settings. Systematic review registration PROSPERO CRD42013003799. PMID:25148933

2017-10-10

The best manner to prevent suicide is to recognize suicidal signs and signals, and know how to respond to them. We aim to study the existing mobile apps for suicide prevention in the literature and the most commonly used virtual stores. Two reviews were carried out. The first was done by searching the most commonly used commercial app stores, which are iTunes and Google Play. The second was a review of mobile health (mHealth) apps in published articles within the last 10 years in the following 7 scientific databases: Science Direct, Medline, PsycINFO, Embase, The Cochrane Library, IEEE Xplore, and Google Scholar. A total of 124 apps related to suicide were found in the cited virtual stores but only 20 apps were specifically designed for suicide prevention. All apps were free and most were designed for Android. Furthermore, 6 relevant papers were found in the indicated scientific databases; in these studies, some real experiences with physicians, caregivers, and families were described. The importance of these people in suicide prevention was indicated. The number of apps regarding suicide prevention is small, and there was little information available from literature searches, indicating that technology-based suicide prevention remains understudied. Many of the apps provided no interactive features. It is important to verify the accuracy of the results of different apps that are available on iOS and Android. The confidence generated by these apps can benefit end users, either by improving their health monitoring or simply to verify their body condition. ©Isabel de la Torre, Gema Castillo, Jon Arambarri, Miguel López-Coronado, Manuel A Franco.

Watwood, Carol L

2016-10-01

The purpose of this study was to identify core journals and other types of literature cited in four major pediatric nursing journals and to characterize coverage of these resources in major bibliographic databases. The study was part of the "Mapping the Literature of Nursing Project" of the Medical Library Association's Nursing and Allied Health Resource Section. It updates a similar analysis published in 2006 and determines whether citation patterns have changed over time. Cited references from articles published in 4 pediatric nursing journals between 2011 and 2013 were collected. Cited journal titles were ranked according to number of times cited and analyzed according to Bradford's Law of Scattering and the 80/20 rule to identify the most frequently cited journals. Five databases were surveyed to assess the coverage of the most-often-cited journals. The most frequently cited non-journal sources were also identified. Journals were the most frequently cited sources, followed by books, government documents, Internet resources, and miscellaneous resources. Most cited sources were cited within ten years of their publication, which was particularly true for government documents and Internet resources. Scopus had complete coverage of the most frequently cited journals, whereas PubMed had nearly complete coverage. Compared with the 2006 study, the list of top-cited journals referenced by pediatric nursing researchers has remained relatively stable, but the number of cited journal titles has increased. Book citations have declined, and Internet and government document references have increased. These findings suggest that librarians should retain subscriptions to frequently cited journal titles, provide efficient document delivery of articles from infrequently used journals, de-emphasize but not eliminate books, and connect patrons with useful open-access Internet resources.

Introduction Incomplete or inconsistent reporting remains a major concern in the biomedical literature. Incomplete or inconsistent reporting may yield the published findings unreliable, irreproducible or sometimes misleading. In this study based on evidence from systematic reviews and surveys that have evaluated the reporting issues in primary biomedical studies, we aim to conduct a scoping review with focuses on (1) the state-of-the-art extent of adherence to the emerging reporting guidelines in primary biomedical research, (2) the inconsistency between protocols or registrations and full reports and (3) the disagreement between abstracts and full-text articles. Methods and analyses We will use a comprehensive search strategy to retrieve all available and eligible systematic reviews and surveys in the literature. We will search the following electronic databases: Web of Science, Excerpta Medica Database (EMBASE), MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Our outcomes are levels of adherence to reporting guidelines, levels of consistency between protocols or registrations and full reports and the agreement between abstracts and full reports, all of which will be expressed as percentages, quality scores or categorised rating (such as high, medium and low). No pooled analyses will be performed quantitatively given the heterogeneity of the included systematic reviews and surveys. Likewise, factors associated with improved completeness and consistency of reporting will be summarised qualitatively. The quality of the included systematic reviews will be evaluated using AMSTAR (a measurement tool to assess systematic reviews). Ethics and dissemination All findings will be published in peer-reviewed journals and relevant conferences. These results may advance our understanding of the extent of incomplete and inconsistent reporting, factors related to improved completeness and consistency of reporting and potential recommendations for various stakeholders in the biomedical community.

Objective To systematically review the available evidence on whether national or international agricultural policies that directly affect the price of food influence the prevalence rates of undernutrition or nutrition-related chronic disease in children and adults. Design Systematic review. Setting Global. Search strategy We systematically searched five databases for published literature (MEDLINE, EconLit, Agricola, AgEcon Search, Scopus) and systematically browsed other databases and relevant organisational websites for unpublished literature. Reference lists of included publications were hand-searched for additional relevant studies. We included studies that evaluated or simulated the effects of national or international food-price-related agricultural policies on nutrition outcomes reporting data collected after 1990 and published in English. Primary and secondary outcomes Prevalence rates of undernutrition (measured with anthropometry or clinical deficiencies) and overnutrition (obesity and nutrition-related chronic diseases including cancer, heart disease and diabetes). Results We identified a total of four relevant reports; two ex post evaluations and two ex ante simulations. A study from India reported on the undernutrition rates in children, and the other three studies from Egypt, the Netherlands and the USA reported on the nutrition-related chronic disease outcomes in adults. Two of the studies assessed the impact of policies that subsidised the price of agricultural outputs and two focused on public food distribution policies. The limited evidence base provided some support for the notion that agricultural policies that change the prices of foods at a national level can have an effect on population-level nutrition and health outcomes. Conclusions A systematic review of the available literature suggests that there is a paucity of robust direct evidence on the impact of agricultural price policies on nutrition and health.

Consistent evidence shows the importance of preventing smoking at young ages, when health behaviours are formed, with long-term consequences on health and survival. Although tobacco control policies and programmes targeting adolescents are widely promoted, the cost-effectiveness of such interventions has not been systematically documented. We performed a systematic review on the cost-effectiveness of policies and programmes preventing tobacco consumption targeting adolescents. We systematically reviewed literature on the (i) cost and effectiveness of (ii) prevention policies targeting (iii) smoking by (iv) adolescents. PubMed, Web of Science, Cochrane, CEA-TUFTS, Health Economic Evaluations, Wiley Online Library, Centre for Reviews and Dissemination Database, the National Institute for Health and Care Excellence and Google Scholar databases were used, and Google search engine was used for other grey literature review. We obtained 793 full-text papers and 19 grey literature documents, from which 16 studies fulfilled the inclusion criteria. Of these, only one was published in the last 5 years, and 15 were performed in high-income countries. Eight analyzed the cost-effectiveness of school-based programmes, five focused on media campaigns and three on legal bans. Policies and programmes were found to be cost-effective in all studies, and both effective and cost-saving in about half of the studies. Evidence is scarce and relatively obsolete, and rarely focused on the evaluation of legal bans. Moreover, no comparisons have been made between different interventions or across different contexts and implementation levels. However, all studies conclude that smoking prevention policies and programmes amongst adolescents are greatly worth their costs. © The Author 2017.

Mathie, Robert T; Hacke, Daniela; Clausen, Jürgen

2012-10-01

Systematic review of the research evidence in veterinary homeopathy has never previously been carried out. This paper presents the search methods, together with categorised lists of retrieved records, that enable us to identify the literature that is acceptable for future systematic review of randomised controlled trials (RCTs) in veterinary homeopathy. All randomised and controlled trials of homeopathic intervention (prophylaxis and/or treatment of disease, in any species except man) were appraised according to pre-specified criteria. The following databases were systematically searched from their inception up to and including March 2011: AMED; Carstens-Stiftung Homeopathic Veterinary Clinical Research (HomVetCR) database; CINAHL; Cochrane Central Register of Controlled Trials; Embase; Hom-Inform; LILACS; PubMed; Science Citation Index; Scopus. One hundred and fifty records were retrieved; 38 satisfied the acceptance criteria (substantive report of a clinical treatment or prophylaxis trial in veterinary homeopathic medicine randomised and controlled and published in a peer-reviewed journal), and were thus eligible for future planned systematic review. Approximately half of the rejected records were theses. Seven species and 27 different species-specific medical conditions were represented in the 38 papers. Similar numbers of papers reported trials of treatment and prophylaxis (n=21 and n=17 respectively) and were controlled against placebo or other than placebo (n=18, n=20 respectively). Most research focused on non-individualised homeopathy (n=35 papers) compared with individualised homeopathy (n=3). The results provide a complete and clarified view of the RCT literature in veterinary homeopathy. We will systematically review the 38 substantive peer-reviewed journal articles under the main headings: treatment trials; prophylaxis trials. Copyright © 2012 The Faculty of Homeopathy.

Frequency of INherited Disorders database (FINDbase) (http://www.findbase.org) is a relational database, derived from the ETHNOS software, recording frequencies of causative mutations leading to inherited disorders worldwide. Database records include the population and ethnic group, the disorder name and the related gene, accompanied by links to any corresponding locus-specific mutation database, to the respective Online Mendelian Inheritance in Man entries and the mutation together with its frequency in that population. The initial information is derived from the published literature, locus-specific databases and genetic disease consortia. FINDbase offers a user-friendly query interface, providing instant access to the list and frequencies of the different mutations. Query outputs can be either in a table or graphical format, accompanied by reference(s) on the data source. Registered users from three different groups, namely administrator, national coordinator and curator, are responsible for database curation and/or data entry/correction online via a password-protected interface. Databaseaccess is free of charge and there are no registration requirements for data querying. FINDbase provides a simple, web-based system for population-based mutation data collection and retrieval and can serve not only as a valuable online tool for molecular genetic testing of inherited disorders but also as a non-profit model for sustainable database funding, in the form of a 'database-journal'.

2016-08-30

Individuals from Black and Asian Minority Ethnic (BAME) groups are less likely to receive a diagnosis and to engage with treatment for depression. This review aims to draw on international literature to summarise what is known about how people specifically of South Asian origin, migrants and non-migrants, understand and experience depressive symptoms. The resulting evidence base will further inform practices aimed at encouraging help-seeking behaviour and treatment uptake. A systematic review and thematic synthesis of qualitative literature conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Using predefined inclusion and exclusion criteria, electronic searches will be conducted across 16 databases. Study quality will be assessed using the Critical Appraisal Skills Programme (CASP). Data will be extracted independently by 2 reviewers. Ethical approval is not required. A comprehensive evidence base of how people from South Asian backgrounds conceptualise and experience depression will better inform the design and delivery of mental health initiatives and advance directions for future research. Findings will be published in a peer-reviewed journal, and disseminated through existing networks for professionals, researchers, patients and the public. CRD42015026120.

Addressing unwarranted clinical variation: A rapid review of current evidence.

Harrison, Reema; Manias, Elizabeth; Mears, Stephen; Heslop, David; Hinchcliff, Reece; Hay, Liz

2018-05-15

Unwarranted clinical variation (UCV) can be described as variation that can only be explained by differences in health system performance. There is a lack of clarity regarding how to define and identify UCV and, once identified, to determine whether it is sufficiently problematic to warrant action. As such, the implementation of systemic approaches to reducing UCV is challenging. A review of approaches to understand, identify, and address UCV was undertaken to determine how conceptual and theoretical frameworks currently attempt to define UCV, the approaches used to identify UCV, and the evidence of their effectiveness. Rapid evidence assessment (REA) methodology was used. A range of text words, synonyms, and subject headings were developed for the major concepts of unwarranted clinical variation, standards (and deviation from these standards), and health care environment. Two electronic databases (Medline and Pubmed) were searched from January 2006 to April 2017, in addition to hand searching of relevant journals, reference lists, and grey literature. Results were merged using reference-management software (Endnote) and duplicates removed. Inclusion criteria were independently applied to potentially relevant articles by 3 reviewers. Findings were presented in a narrative synthesis to highlight key concepts addressed in the published literature. A total of 48 relevant publications were included in the review; 21 articles were identified as eligible from the database search, 4 from hand searching published work and 23 from the grey literature. The search process highlighted the voluminous literature reporting clinical variation internationally; yet, there is a dearth of evidence regarding systematic approaches to identifying or addressing UCV. Wennberg's classification framework is commonly cited in relation to classifying variation, but no single approach is agreed upon to systematically explore and address UCV. The instances of UCV that warrant investigation and action are largely determined at a systems level currently, and stakeholder engagement in this process is limited. Lack of consensus on an evidence-based definition for UCV remains a substantial barrier to progress in this field. © 2018 John Wiley & Sons, Ltd.

Emperipolesis, entosis and cell cannibalism: Demystifying the cloud.

2017-01-01

There are intense published data in literature related to cell engulfment phenomena such as emperipolesis, entosis and cell cannibalism. All these are closely related phenomena with a very fine line of differences. Its correct identification has a significant diagnostic and prognostic value. After extensive literature search, a gap of knowledge was found in concept designing and clarity about understanding of aforementioned terminologies. The authors have attempted to review data of these closely knit terminologies and further organize its characteristic appearances, pathogenetic aspects and prognostic implications. The data published in English Language, from 1925 to 2015, were collected using keywords such as emperipolesis, entosis and cell cannibalism through scientific database systems such as MEDLINE, Science Direct, Cochrane Library and Google Scholar. Articles were selected which have focused to explain the phenomenon, presentation and pathogenesis of one or more of this phenomenon. A total of 48 articles were retrieved, thirty of which were selected. The various cell engulfment phenomena are very similar looking but operate through entirely different pathways.

To compare the economic value of EDWARDS INTUITY Elite™ (EIE) valve system for rapid-deployment aortic valve replacement (RDAVR) in a full sternotomy (FS) approach (EIE-FS-RDAVR) versus FS-AVR using conventional stented bioprosthesis. A simulation model to compare each treatment's 30-day inpatient utilization and complication rates utilized: clinical end points obtained from the TRANSFORM trial patient subset (EIE-FS-RDAVR) and a best evidence review of the published literature (FS-AVR); and costs from the Premier database and published literature. EIE-FS-RDAVR costs $800 less than FS-AVR per surgery episode attributable to lowered complication rates and utilization. Combined with the lower mortality, EIE-FS-RDAVR was a superior (dominant) technology versus FS-AVR. This preliminary investigation of EIE-FS-RDAVR versus conventional FS-AVR found the EIE valve offered superior economic value over a 30-day period. Real-world analyses with additional long-term follow-up are needed to evaluate if this result can be replicated over a longer timeframe.

The Irish government published its primary care strategy, Primary Care: A New Direction in 2001. Progress with the implementation of Primary care teams is modest. The aim of this paper is to map the Irish grey literature and peer-reviewed publications to determine what research has been carried out in relation to primary care teams, the reform process and interdisciplinary working in primary care in Ireland. This scoping review employed three methods: a review of Web of Science, Medline and Embase databases, an email survey of researchers across academic institutions, the HSE and independent researchers and a review of Lenus and the Health Well repository. N = 123 outputs were identified. N = 14 were selected for inclusion. A thematic analysis was undertaken. Common themes identified were resources, GP participation, leadership, clarity regarding roles in primary care teams, skills and knowledge for primary care team working, communication and community. There is evidence of significant problems that disrupt team formation and functioning that warrants more comprehensive research.

2017-08-28

This study charts the growth of the drug delivery literature published during 1974-2015 from journals indexed in the Science Citation Index Expanded database. The growth of publications on drug delivery paralleled the total scientific publications for three decades (1974-2003); however, from 2004 to 2015 it exploded fourfold, while the total increased only 1.75 fold. Industrialized countries (USA, UK, Germany, Japan, Italy, France and Canada) were the most prolific during the first decades, but in 2014-2015 China, India and South Korea ranked 1st, 3rd and 4th respectively among the productive countries. The number of participating countries increased fivefold (from 19 to 96). During the last 15years, the journals targeted by drug delivery research increased nearly 2.4 fold (416 to 1001) and three journals (Journal of Controlled Release, Advanced Drug Delivery Reviews, and International Journal of Pharmaceutics) published nearly one-fifth of the drug delivery research in 2014-2015.

Newton, Alice W

2016-06-01

This review addresses some of the more salient articles in the field of child maltreatment published in 2015, with a goal of helping the general practitioner understand the evolution of research in the field of child abuse pediatrics (a board-certified specialty since 2009). Researchers continue to refine the database for child abuse pediatrics. Several articles focus on the inconsistencies in approach to the evaluation of possible physical child abuse between hospitals and practitioners. Multiple researchers aim to develop a protocol that standardizes the response to findings of a sentinel injury, such as a rib fracture, abdominal trauma, or unexplained bruising in a nonambulatory infant. Professionals are also working to improve our understanding about the impact of trauma on children and how best to ameliorate its effects. With solid, evidence-based literature published on various topics in the field of child abuse pediatrics, experts work to refine and unify the clinician's approach to the evaluation of possible physical abuse.

The aim of this study was to map an academic hospital's nursing contributions to the literature using bibliometric methods. Nurse executives continue to search for ways to share knowledge gained in the clinical setting. Manuscripts from clinical nurses must increase to advance the science of nursing practice and nursing administration. A search of electronic databases and curriculum vitae provided bibliographic data for University of Colorado Hospital (UCH) nurses from 1990 to 2012. Bibliometric techniques were used for publication counts and citation analysis. A review of the infrastructure supporting scholarly work was undertaken. A total of 191 journal articles, 9 books, 103 book chapters, 5 manuals, and 46 manual chapters were published by UCH nurses. Author productivity steadily increased. Citation analysis indicated that the works published were used by others. The h-index for UCH authors was 25. The hospital culture, interdisciplinary practice, and the role of the research nurse scientists had an impact on study results.

Batista Rodríguez, Gabriela; Balla, Andrea; Fernández-Ananín, Sonia; Balagué, Carmen; Targarona, Eduard M

2018-05-01

The term big data refers to databases that include large amounts of information used in various areas of knowledge. Currently, there are large databases that allow the evaluation of postoperative evolution, such as the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS), and the National Cancer Database (NCDB). The aim of this review was to evaluate the clinical impact of information obtained from these registries regarding gastroesophageal surgery. A systematic review using the Meta-analysis of Observational Studies in Epidemiology guidelines was performed. The research was carried out using the PubMed database identifying 251 articles. All outcomes related to gastroesophageal surgery were analyzed. A total of 34 articles published between January 2007 and July 2017 were included, for a total of 345 697 patients. Studies were analyzed and divided according to the type of surgery and main theme in (1) esophageal surgery and (2) gastric surgery. The information provided by these databases is an effective way to obtain levels of evidence not obtainable by conventional methods. Furthermore, this information is useful for the external validation of previous studies, to establish benchmarks that allow comparisons between centers and have a positive impact on the quality of care.

A taxonomy has been developed for outcomes in medical research to help improve knowledge discovery.

There is increasing recognition that insufficient attention has been paid to the choice of outcomes measured in clinical trials. The lack of a standardized outcome classification system results in inconsistencies due to ambiguity and variation in how outcomes are described across different studies. Being able to classify by outcome would increase efficiency in searching sources such as clinical trial registries, patient registries, the Cochrane Database of Systematic Reviews, and the Core Outcome Measures in Effectiveness Trials (COMET) database of core outcome sets (COS), thus aiding knowledge discovery. A literature review was carried out to determine existing outcome classification systems, none of which were sufficiently comprehensive or granular for classification of all potential outcomes from clinical trials. A new taxonomy for outcome classification was developed, and as proof of principle, outcomes extracted from all published COS in the COMET database, selected Cochrane reviews, and clinical trial registry entries were classified using this new system. Application of this new taxonomy to COS in the COMET database revealed that 274/299 (92%) COS include at least one physiological outcome, whereas only 177 (59%) include at least one measure of impact (global quality of life or some measure of functioning) and only 105 (35%) made reference to adverse events. This outcome taxonomy will be used to annotate outcomes included in COS within the COMET database and is currently being piloted for use in Cochrane Reviews within the Cochrane Linked Data Project. Wider implementation of this standard taxonomy in trial and systematic review databases and registries will further promote efficient searching, reporting, and classification of trial outcomes.

Health information needs, source preferences and engagement behaviours of women with metastatic breast cancer across the care continuum: protocol for a scoping review.

PubMed

Tucker, Carol A; Martin, M Pilar; Jones, Ray B

2017-02-17

The health information needs, information source preferences and engagement behaviours of women with metastatic breast cancer (mBC) depend on personal characteristics such as education level, prior knowledge, clinical complications, comorbidities and where they are in the cancer journey. A thorough understanding of the information behaviours of women living with mBC is essential to the provision of optimal care. A preliminary literature review suggests that there is little research on this topic, but that there may be lessons from a slightly broader literature. This review will identify what is known and what is not known about the health information needs, acquisition and influences of women with mBC across the care continuum. Findings will help to identify research needs and specific areas where in-depth systematic reviews may be feasible, as well as inform evidence-based interventions to address the health information needs of female patients with mBC with different demographics and characteristics and across the mBC journey. A scoping review will be performed using the guidelines of Arksey and O'Malley as updated by subsequent authors to systematically search scientific and grey literature for articles in English that discuss the health information needs, source preferences, engagement styles, and associated personal and medical attributes of women ≥18 years living with mBC at different stages of the disease course. A variety of databases (including Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Excerpta Medica Database (EMBASE), Academic Search Premier, Cochrane Database of Systematic Reviews, PsycINFO, Health Source: Nursing/Academic Edition, and PQDT Open), oncology, patient advocacy and governmental websites will be searched from inception to present day. Research and non-research literature will be included; no study designs will be excluded. The six-stage Arksey and O'Malley scoping review methodological framework involves: (1) identifying the research question; (2) searching for relevant studies; (3) selecting studies; (4) charting the data; (5) collating, summarising and reporting the results; and (6) consulting with stakeholders to inform or validate study findings (optional). Data will be extracted and analysed using a thematic chart and descriptive content analysis. Being a secondary analysis, this research will not require ethics approval. Results will be disseminated through patient support organisations and websites and publications targeting healthcare professionals, advocates and patients.

New electron-energy transfer rates for vibrational excitation of O2

NASA Astrophysics Data System (ADS)

Jones, D. B.; Campbell, L.; Bottema, M. J.; Brunger, M. J.

2003-09-01

We report on our computation of electron-energy transfer rates for vibrational excitation of O2. This work was necessitated by inadequacies in the electron-impact cross section databases employed in previous studies and, in one case, an inaccurate approximate formulation to the rate equation. Both these inadequacies led to incorrect energy transfer rates being published in the literature. We also demonstrate the importance of using cross sections that encompass an energy range that is extended enough to appropriately describe the environment under investigation.

Medical Guidelines for Airline Travel provide information that enables healthcare providers to properly advise patients who plan to travel by air. Although there are no publicly available databases providing information on the number of in-flight medical emergencies, the few studies published in the literature indicate that they are uncommon. Minor illnesses such as near-fainting, dizziness, and hyperventilation occur more frequently. However, serious illnesses, such as seizures and myocardial infarction, also occur. In-flight deaths are also rare.

The aim of this study was to perform a literature review of published in-vitro and ex-vivo studies, which evaluated microbial leakage in endodontics in the past 10 years. A comprehensive electronic literature search was carried out in PubMed database for English articles published from 2005 to 2016 using the keywords "endodontics," " in vitro ," " ex vivo ," "microbial leakage," "microbial penetration," "saliva," " Enterococcus faecalis ," " E. faecalis ," "endodontic sealers," "temporary filling material," "apical plug," "mineral trioxide aggregate," and "MTA." The keywords were combined using Boolean operators AND/OR. Based on our search strategy, 33 relevant articles were included in the study. There are three main methods for assessment of bacterial microleakage, namely, (A) the dual-chamber leakage model, (B) detection of bacteria using a scanning electron microscope (SEM), and (C) polymerase chain reaction. All bacterial leakage models have some limitations and may yield different results compared to other microleakage evaluation techniques (i.e., dye penetration, fluid filtration, or electrochemical tests). The results of SEM correlated with those of microbial leakage test in most studies. Microbial leakage test using saliva better simulates the clinical setting for assessment of the leakage of single or mixed bacterial species.

Rail-related suicide is a relatively rare but extremely lethal method of suicide that can have far-reaching consequences. The aim of the systematic literature review was to analyze the existing literature on the effectiveness of rail-suicide prevention activities. Databases used were Scopus, Medline, and ProQuest. The search terms used were "suicid*," "prevent*," "rail*," or "train." English-language studies published in peer-reviewed journals between 1 January 1990 and 30 April 2015 that presented an overview of rail-related suicide prevention activities and included an analysis of effectiveness were used. We retrieved 1,229 results in the original search with nine papers presenting empirical evidence. Three studies in the review analyzed the effectiveness of platform screen doors and another three analyzed the installation of blue lights, two papers analyzed the effectiveness of suicide pits, and one included the influence of media reporting guidelines. Platform screen doors, suicide pits, blue lights, and improved media guidelines all have the potential to reduce rail-related suicide events and deaths. The review was restricted to English-language peer-reviewed papers published within the chosen time period. © 2016 John Wiley & Sons Australia, Ltd.

Assessing the relationships between nurse working conditions and patient outcomes: systematic literature review.

PubMed

Bae, Sung-Heui

2011-09-01

The purpose of the study was to systematically evaluate nurse working conditions and to review the literature dealing with their association with patient outcomes. Improving nurse working conditions is essential to address nursing shortages. Although general reviews of the literature support the positive link between working conditions and patient outcomes, definitive evidence has been lacking. A search of six electronic bibliographic databases was conducted for the primary research published in English, from January 2000 to October 2009. The concepts of working conditions were categorized into 10 groups of working conditions. A total of 69 relationships between working conditions and patient outcomes were examined. Increased attention has been drawn to nurse working conditions resulting from nursing shortages. The findings of this review suggested that the evidence supporting positive relationships between working conditions and patient outcomes is inconclusive. Further studies of a longitudinal and interventional nature in various settings are needed to advance knowledge of the complex contextual and multivariate influences among nurse working conditions and patient outcomes. Efforts to improve working conditions should be made in various health-care work settings to ensure patient safety and improve patient quality of outcomes. 2011 Blackwell Publishing Ltd.

Factors influencing pharmacist performance: a review of the peer-reviewed literature.

To undertake a review of peer-reviewed literature to explore factors affecting pharmacists' performance. The following databases were searched: Medline, Embase, Scopus, ISI Web of Knowledge and PsychInfo. Inclusion criteria were: English language only, published between 1990 and 2010 and published in the United Kingdom (UK), United States of America (USA), Canada, Australia, New Zealand or Europe. The search strategy identified 37 items. The review found that there was some evidence to suggest that pharmacists with certain characteristics (e.g. being male, being of ethnic minority origin, working in community pharmacy and having trained overseas) were more likely to experience performance problems. Factors relating to workload and work environment were associated with performance problems, particularly in relation to errors. There was some limited evidence to suggest that experiencing problems with alcohol or drugs could negatively impact on pharmacists' performance. The findings suggest that pharmacist performance may be affected by multiple factors, including personal characteristics such as age, gender, ethnicity, place of primary qualification, factors associated with the workplace and mental and physical health problems. The evidence is not unequivocal and gaps in the literature exist, suggesting that pharmacist performance is an under-researched area. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Preterm infants are babies born alive before 37 weeks. Many survived infants concomitant with defects of growth and development, a lifetime of disability usually as following when insufficient intervention. In early intervention of preterm infants, pediatric Tuina shows good effect in many Chinese and some English clinical trials. This systematic review is aimed to evaluate the efficacy and safety of pediatric Tuina for promoting growth and development of preterm infants. The electronic databases of Cochrane Library, MEDLINE, EBASE, Web of Science, Springer, World Health Organization International Clinical Trials Registry Platform, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wan-fang database, Chinese Scientific Journal Database, and other databases will be searched from establishment to April 1, 2018. All published randomized controlled trials (RCTs) about this topic will be included. Two independent researchers will operate article retrieval, screening, quality evaluation, and data analyses by Review Manager (V.5.3.5). Meta-analyses, subgroup analysis, and/or descriptive analysis will be performed based on included data conditions. High-quality synthesis and/or descriptive analysis of current evidence will be provided from weight increase, motor development, neuropsychological development, length of stay, days of weight recovery to birthweight, days on supplemental oxygen, daily sleep duration, and side effects. This study will provide the evidence of whether pediatric Tuina is an effective early intervention for preterm infants. There is no requirement of ethical approval and informed consent, and it will be in print or published by electronic copies. This systematic review protocol has been registered in the PROSPERO network (No. CRD42018090563).

2016-11-25

Mobile health (mHealth) has been described as a health enabling tool that impacts positively on the health system in terms of improved access, quality and cost of health care. The proposed systematic review will examine the impact of mHealth on health systems by assessing access, quality and cost of health care as indicators. The systematic review will include literature from various sources including published and unpublished/grey literature. The databases to be searched include: PubMed, Cochrane Library, Google Scholar, NHS Health Technology Assessment Database and Web of Science. The reference lists of studies will be screened and conference proceedings searched for additional eligible reports. Literature to be included will have mHealth as the primary intervention. Two authors will independently screen the search output, select studies and extract data; discrepancies will be resolved by consensus and discussion with the assistance of the third author. The systematic review will inform policy makers, investors, health professionals, technologists and engineers about the impact of mHealth in strengthening the health system. In particular, it will focus on three metrics to determine whether mHealth strengthens the health system, namely quality of, access to and cost of health care services.

Systematic reviews and meta-analysis have become an important of biomedical literature, and they provide the “highest level of evidence” for various clinical questions. There are a lot of studies – sometimes with contradictory conclusions – on a particular topic in literature. Hence, as a clinician, which results will you believe? What will you tell your patient? Which drug is better? A systematic review or a meta-analysis may help us answer these questions. In addition, it may also help us understand the quality of the articles in literature or the type of studies that have been conducted and published (example, randomized trials or observational studies). The first step it to identify a research question for systematic review or meta-analysis. The next step is to identify the articles that will be included in the study. This will be done by searching various databases; it is important that the researcher should search for articles in more than one database. It will also be useful to form a group of researchers and statisticians that have expertise in conducting systematic reviews and meta-analysis before initiating them. We strongly encourage the readers to register their proposed review/meta-analysis with PROSPERO. Finally, these studies should be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis checklist. PMID:27904176

Concept analysis. This paper is a report on the analysis of the concept of tone in chiropractic. The purpose of this paper is to clarify the concept of tone as originally understood by Daniel David Palmer from 1895 to 1914 and to monitor its evolution over time. Data was sourced from Palmer's original work, published between 1895 and 1914. A literature search from 1980 to 2016 was also performed on the online databases CINHAL, PubMed and Scopus with key terms including 'tone', 'chiropractic', 'Palmer', 'vitalism', 'health', 'homeostasis', 'holism' and 'wellness'. Finally hand-searches were conducted through chiropractic books and professional literature from 1906 to 1980 for any references to 'tone'. Rodgers' evolutionary method of analysis was used to categorise the data in relation to the surrogates, attributes, references, antecedents and consequences of tone. A total of 49 references were found: five from publications by Palmer; three from the database searches, and; the remaining 41 from professional books, trade journals and websites. There is no clear interpretation of tone in the contemporary chiropractic literature. Tone is closely aligned with functional neurology and can be understood as an interface between the metaphysical and the biomedical. Using the concept of tone as a foundation for practice could strengthen the identity of the chiropractic profession. Copyright © 2017 Elsevier Ltd. All rights reserved.

2015-01-01

Systematic reviews are fundamental sources of knowledge on the state-of-the-art interventions for various clinical problems. One of the essential components in carrying out a systematic review is that of developing a comprehensive literature search. Three Cochrane systematic reviews published in 2012 were retrieved using the MeSH descriptor breast neoplasms/surgery, and analyzed with respect to the information sources used and the search strategies adopted. In March 2014, an update of one of the reviews retrieved was also considered in the study. The number of databases queried for each review ranged between three and seven. All the reviews reported the search strategies adopted, however some only partially. All the reviews explicitly claimed that the searches applied no language restriction although sources such as the free database Lilacs (in Spanish and Portuguese) was not consulted. To improve the quality it is necessary to apply standards in carrying out systematic reviews (as laid down in the MECIR project). To meet these standards concerning literature searching, professional information retrieval specialist staff should be involved. The peer review committee in charge of evaluating the publication of a systematic review should also include specialists in information retrieval for assessing the quality of the literature search.

Fourie, Ina

2009-09-01

A review, focusing on emotion, was conducted of reported studies on the information behaviour of healthcare professionals (2004-2008). Findings were intended to offer guidelines on information services and information literacy training, to note gaps in research and to raise research interest. Databases were searched for literature published from January 2004 to December 2008 and indexed on eric, Library and Information Science Abstracts, medline, PsycINFO, Social Services Abstracts, Sociological Abstracts, Health Source: Nursing/Academic Edition; Library, Information Science & Technology Abstracts; Psychology and Behavioral Sciences Collection; Social Work Abstracts; SocINDEX with Full Text; SPORTDiscus; cinhal; and the ISI Web of Knowledge databases. Key journals were manually scanned and citations followed. Literature was included if reporting on issues concerning emotion. Emotion in information behaviour in healthcare contexts is scantily addressed. This review, however, offers some insight into the difficulty in identifying and expressing information needs; sense making and the need to fill knowledge gaps; uncertainty; personality and coping skills; motivation to seeking information; emotional experiences during information seeking; self-confidence and attitude; emotional factors in the selection of information channels; and seeking information for psychological or emotional reasons. Suggestions following findings, address information literacy programs, information services and research gaps.

Medicolegal Death Scene Investigations After Natural Disaster- and Weather-Related Events: A Review of the Literature

Rocha, Luciana A.; Fromknecht, Catharine Q.; Redman, Sarah Davis; Brady, Joanne E.; Hodge, Sarah E.; Noe, Rebecca S.

2017-01-01

Background The number of disaster-related deaths recorded by vital statistics departments often differs from that reported by other agencies, including the National Oceanic and Atmospheric Administration-National Weather Service storm database and the American Red Cross. The Centers for Disease Control and Prevention (CDC) has launched an effort to improve disaster-related death scene investigation reporting practices to make data more comparable across jurisdictions, improve accuracy of reporting disaster-related deaths, and enhance identification of risk and protective factors. We conducted a literature review to examine how death scene data are collected and how such data are used to determine disaster relatedness. Methods Two analysts conducted a parallel search using Google and Google Scholar. We reviewed published peer-reviewed articles and unpublished documents including relevant forms, protocols, and worksheets from coroners, medical examiners, and death scene investigators. Results We identified 177 documents: 32 published peer-reviewed articles and 145 other documents (grey literature). Published articles suggested no consistent approach for attributing deaths to a disaster. Researchers generally depended on death certificates to identify disaster-related deaths; several studies also drew on supplemental sources, including medical examiner, coroner, and active surveillance reports. Conclusions These results highlight the critical importance of consistent, accurate data collection during a death investigation. Review of the grey literature found variation in use of death scene data collection tools, indicating the potential for widespread inconsistency in data captured for routine reporting and public health surveillance. Findings from this review will be used to develop guidelines and tools for capturing disaster-related death investigation data. PMID:28845205

The aim of this study was to provide a descriptive overview of the impact and production of literature on dietary therapies for epilepsy and perform a citation analysis of the related research articles. We searched for 'ketogenic OR low-glycemic OR medium chain OR modified Atkins in TITLE AND epilep*' in Title/Abstract/Keyword in Scopus database. A total of 661 references were retrieved, 80% had been published after 2000s, 87% were published in English, and 39% of the publications were published in nine journals. The majority (76.3%) of research articles describe the clinical application of the dietary therapies regarding the classical ketogenic diet (80%), followed by the modified Atkins diet (11.5%), medium chain triglyceride diet (6.4%), and low glycemic index treatment (2.0%); the remaining are basic science studies on the mechanisms of action. The citation analysis revealed that the latter have the highest percentage variation in citation per publication across the years. Concerning the article cohorts, the greatest number of citations per publication was in 1998. The overview of the literature on the dietary therapy of epilepsy evidences a growing interest in the field with a striking prevalence of clinical over basic science studies. The most cited clinical studies have validated the efficacy of the dietary therapies; the few studies on the mechanisms of action received a great number of citations. Bibliometric analysis measuring the trends and the impact of the scientific literature would help researchers to a best knowledge of this specific topic.

2013-05-01

This systematic review provides an overview of the literature published on Releasing Time to Care: The Productive Ward between 2005 and June 2011. Releasing Time to Care: The Productive Ward programme was developed by the NHS Institute for Innovation and Improvement and launched in England in 2007. The programme comprises thirteen modules that aim to increase time for direct patient care, improve the patient and staff experience and make changes to the ward environment to improve efficiency. A systematic literature review. The terms 'Releasing Time to Care' and 'Productive Ward' were applied to key healthcare databases; CINAHL, Medline, Science Direct, ProQuest, Health Business Elite, British Nursing Index, Embase, Health Management Information Consortium and PsychInfo. All papers were read and subject to a quality assessment. The literature search identified 95 unique sources. A lack of research on The Productive Ward programme meant it was necessary to include non-empirical literature. In total, 18 articles met the inclusion criteria. Seven key themes were identified: the patient and staff experience, direct care time, patient safety, financial impact, embedding and sustainability, executive support and leadership, and common barriers and determinants of success. It also highlighted areas that require further exploration such as long-term sustainability of the programme and consistent data measurement between organisations. The review tentatively reports how The Productive Ward programme has been used to transform nursing practice for the benefit of patients and frontline staff, and how it resulted in cost savings. The literature review identified a potential positive results bias in the current literature whereby favourable outcomes were reported. This paper summarises the types of evidence and current literature on The Productive Ward providing a reference for frontline staff implementing the programme. © 2013 Blackwell Publishing Ltd.

Public health and epidemiology journals published in Brazil and other Portuguese speaking countries

It is well known that papers written in languages other than English have a great risk of being ignored simply because these languages are not accessible to the international scientific community. The objective of this paper is to facilitate the access to the public health and epidemiology literature available in Portuguese speaking countries. It was found that it is particularly concentrated in Brazil, with some few examples in Portugal and none in other Portuguese speaking countries. This literature is predominantly written in Portuguese, but also in other languages such as English or Spanish. The paper describes the several journals, as well as the bibliographic databases that index these journals and how to access them. Most journals provide open-access with direct links in the indexing databases. The importance of this scientific production for the development of epidemiology as a scientific discipline and as a basic discipline for public health practice is discussed. To marginalize these publications has implications for a more balanced knowledge and understanding of the health problems and their determinants at a world-wide level. PMID:18826592

The scoping review has become an increasingly popular approach for synthesizing research evidence. It is a relatively new approach for which a universal study definition or definitive procedure has not been established. The purpose of this scoping review was to provide an overview of scoping reviews in the literature. A scoping review was conducted using the Arksey and O'Malley framework. A search was conducted in four bibliographic databases and the gray literature to identify scoping review studies. Review selection and characterization were performed by two independent reviewers using pretested forms. The search identified 344 scoping reviews published from 1999 to October 2012. The reviews varied in terms of purpose, methodology, and detail of reporting. Nearly three-quarter of reviews (74.1%) addressed a health topic. Study completion times varied from 2 weeks to 20 months, and 51% utilized a published methodological framework. Quality assessment of included studies was infrequently performed (22.38%). Scoping reviews are a relatively new but increasingly common approach for mapping broad topics. Because of variability in their conduct, there is a need for their methodological standardization to ensure the utility and strength of evidence. © 2014 The Authors.

Objective To evaluate the quantity and quality of published literature conducted by pharmacy practice faculty members in US colleges and schools of pharmacy for the years 2001-2003. Methods The Web of Science bibliographic database was used to identify publication citations for the years 2001-2003, which were then evaluated in a number of different ways. Faculty members were identified using American Association of Colleges of Pharmacy rosters for the 2000-2001, 2001-2002, and 2002-2003 academic years. Results Two thousand three hundred seventy-four pharmacy practice faculty members generated 1,896 publications in Web of Science searchable journals. A small number of faculty members (2.1%) were responsible for a large proportion of publications (30.6%), and only 4.9% of faculty members published 2 or more publications in these journals per year. The average impact factor for the top 200 publications was 7.6. Conclusion Pharmacy practice faculty members contributed substantially to the biomedical literature and their work has had an important impact. A substantial portion of this work has come from a small subset of faculty members. PMID:17619644

There is a worldwide problem of acute liver failure and mortality associated with remaining on the waiting for a liver transplant. In this study, we highlight results published in recent years by leading transplant centers in evaluating imatinib-induced acute liver failure in chronic myeloid leukemia and follow-up in liver transplantation. A 36-year-old brown-skinned woman (mixed Brazilian race) diagnosed 1 year earlier with chronic myeloid leukemia was started after delivery of a baby and continued for 6 months with imatinib mesylate (selective inhibitor of Bcr-Abl tyrosine kinase), which induced liver failure. We conducted a literature review using the PubMed database for articles published through September 2017, and we demonstrate a role of liver transplant in this situation for imatinib-induced liver failure. We report previously published results and a successful liver transplant after acute liver failure due to imatinib-induced in chronic myeloid leukemia treatment. We report a case of a successful liver transplant after acute liver failure resulting from imatinib-induced chronic myeloid leukemia treatment. The literature reveals the importance of prompt acute liver failure diagnosis and treatment with liver transplant in selected cases.

Background In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required. Development and Testing of the Ontology Here we present the Mammalian Feeding Muscle Ontology (MFMO), a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED, https://feedexp.org/), a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing) in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions). We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar. Results and Significance Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive set of results can be obtained. The broader scientific and publishing communities should consider taking up the challenge of semantically enabled search capabilities. PMID:26870952

Respiratory disease remains one of the leading causes of morbidity and mortality in China. However, little is known about the research status of respirology in three major regions of China-Mainland (ML), Hong Kong (HK) and Taiwan (TW). A 10-year survey of literature was conducted to compare the three regions' outputs in the research of respirology. A bibliometric study. China. A literature search in PubMed database, updated as of September 2012, led to the identification of the related articles from 2000 to 2009. The number of total articles, randomised controlled trials, case reports, meta-analysis, impact factors (IF), citations and articles published in top general medicine journals was collected for quantity and quality comparisons. 2208 articles were collected, 814 from ML, 909 from TW and 485 from HK. The total number of articles from the three regions has increased significantly from 2000 to 2009. The number of articles published per year from ML has exceeded that from HK in 2005 and TW in 2008. The accumulated IF of articles from TW (3192.417) was much higher than that from ML (2409.956) and HK (1898.312). HK got the highest average IF of respirology articles and the majority of articles were published in top general medicine journals. The total number of published articles from the three major regions of China has increased notably from 2000 to 2009. The annual number of publications by ML researchers exceeded those from TW and HK. However, the quality of articles from TW and HK is better than that from ML.

Rapid developments in e-cigarettes, or electronic nicotine delivery systems (ENDS), and the evolution of the overall tobacco product marketplace warrant frequent evaluation of the published literature. The purpose of this article is to report updated findings from a comprehensive review of the published scientific literature on ENDS. The authors conducted a systematic review of published empirical research literature on ENDS through May 31, 2016, using a detailed search strategy in the PubMed electronic database, expert review, and additional targeted searches. Included studies presented empirical findings and were coded to at least one of nine topics: (1) Product Features; (2) Health Effects; (3) Consumer Perceptions; (4) Patterns of Use; (5) Potential to Induce Dependence; (6) Smoking Cessation; (7) Marketing and Communication; (8) Sales; and (9) Policies; reviews and commentaries were excluded. Data from included studies were extracted by multiple coders (October 2015 to August 2016) into a standardized form and synthesized qualitatively by topic. There were 687 articles included in this systematic review. The majority of studies assessed patterns of ENDS use and consumer perceptions of ENDS, followed by studies examining health effects of vaping and product features. Studies indicate that ENDS are increasing in use, particularly among current smokers, pose substantially less harm to smokers than cigarettes, are being used to reduce/quit smoking, and are widely available. More longitudinal studies and controlled trials are needed to evaluate the impact of ENDS on population-level tobacco use and determine the health effects of longer-term vaping.

Published literature was searched for epidemiological studies of dengue disease, using specific search strategies for each electronic database; 237 relevant data sources were identified, 28 of which fulfilled the inclusion criteria. The epidemiology of dengue disease in Malaysia was characterized by a non-linear increase in the number of reported cases from 7,103 in 2000 to 46,171 in 2010, and a shift in the age range predominance from children toward adults. The overall increase in dengue disease was accompanied by a rise in the number, but not the proportion, of severe cases. The dominant circulating dengue virus serotypes changed continually over the decade and differed between states. Several gaps in epidemiological knowledge were identified; in particular, studies of regional differences, age-stratified seroprevalence, and hospital admissions. PROSPERO #CRD42012002293.

This review gives a comprehensive overview on the technical perspective of personal health monitoring. It is designed to build a mutual basis for the project partners of the PHM-Ethics project. A literature search was conducted to screen pertinent literature databases for relevant publications. All review papers that were retrieved were analyzed. The increasing number of publications that are published per year shows that the field of personal health monitoring is of growing interest in the research community. Most publications deal with telemonitoring, thus forming the core technology of personal health monitoring. Measured parameters, fields of application, participants and stakeholders are described. Moreover an outlook on information and communication technology that foster the integration possibilities of personal health monitoring into decision making and remote monitoring of individual people's health is provided. The removal of the technological barriers opens new perspectives in health and health care delivery using home monitoring applications.

To identify scientific studies and to deepen the knowledge of peripheral neuropathies induced by chemotherapy antineoplastic, seeking evidence for assistance to cancer patients. Integrative review of the literature conducted in the databases Latin American and Caribbean Health Sciences (LILACS), Scientific Electronic Library Online (SciELO), Medical Literature Analysis (PubMed/MEDLINE), the Cochrane Library and the Spanish Bibliographic Index Health Sciences (IBECS). The sample consisted of 15 studies published between 2005-2014 that met the inclusion criteria. Studies showed aspects related to advanced age, main symptoms of neuropathy and chemotherapy agents as important adverse effect of neuropathy. We identified a small number of studies that addressed the topic, as well as low production of evidence related to interventions with positive results. It is considered important to develop new studies proposed for the prevention and/or treatment, enabling adjustment of the patient's cancer chemotherapy and consequently better service.

A wealth of valuable data is locked within the millions of research articles published each year. Reading and extracting pertinent information from those articles has become an unmanageable task for scientists. This problem hinders scientific progress by making it hard to build on results buried in literature. Moreover, these data are loosely structured, encoded in manuscripts of various formats, embedded in different content types, and are, in general, not machine accessible. We present a hybrid human-computer solution for semi-automatically extracting scientific facts from literature. This solution combines an automated discovery, download, and extraction phase with a semi-expert crowd assembled from students to extract specific scientific facts. To evaluate our approach we apply it to a challenging molecular engineering scenario, extraction of a polymer property: the Flory-Huggins interaction parameter. We demonstrate useful contributions to a comprehensive database of polymer properties.

Disorders of the long head of biceps tendon are common in clinical practice. Their causes could be degenerative, inflammatory, instability (subluxation or luxation) or traumatic. They are generally associated to other diseases of the shoulder, mainly rotator cuff injuries. Currently, there is controversy in the literature regarding the indications for surgical treatment and the choice of the best technique for each case, due to the possibility of esthetic deformity, loss of muscle strength, and residual pain. The objective of this study was to identify the indications for surgical treatment, the best surgical technique, and the advantages and disadvantages of each technique described in the orthopedic literature for the treatment of long head of biceps tendon injuries. A revision of the orthopedic medical literature on the following databases: Biblioteca Regional de Medicina (BIREME), Medline, PubMed, Cochrane Library and Google Scholar, comprising articles published in the period from 1991 to 2015.

Hospital Nurses' Work Environment Characteristics and Patient Safety Outcomes: A Literature Review.

PubMed

Lee, Seung Eun; Scott, Linda D

2018-01-01

This integrative literature review assesses the relationship between hospital nurses' work environment characteristics and patient safety outcomes and recommends directions for future research based on examination of the literature. Using an electronic search of five databases, 18 studies published in English between 1999 and 2016 were identified for review. All but one study used a cross-sectional design, and only four used a conceptual/theoretical framework to guide the research. No definition of work environment was provided in most studies. Differing variables and instruments were used to measure patient outcomes, and findings regarding the effects of work environment on patient outcomes were inconsistent. To clarify the relationship between nurses' work environment characteristics and patient safety outcomes, researchers should consider using a longitudinal study design, using a theoretical foundation, and providing clear operational definitions of concepts. Moreover, given the inconsistent findings of previous studies, they should choose their measurement methodologies with care.

Drug-drug interaction databases are an important tool to increase drug safety in polypharmacy. There are several drug interaction databases available but it is unclear which one shows the best results and therefore increases safety for the user of the databases and the patients. So far, there has been no validation of German drug interaction databases. Validation of German drug interaction databases regarding the number of hits, mechanisms of drug interaction, references, clinical advice, and severity of the interaction. A total of 36 drug interactions which were published in the last 3-5 years were checked in 5 different databases. Besides the number of hits, it was also documented if the mechanism was correct, clinical advice was given, primary literature was cited, and the severity level of the drug-drug interaction was given. All databases showed weaknesses regarding the hit rate of the tested drug interactions, with a maximum of 67.7% hits. The highest score in this validation was achieved by MediQ with 104 out of 180 points. PsiacOnline achieved 83 points, arznei-telegramm® 58, ifap index® 54 and the ABDA-database 49 points. Based on this validation MediQ seems to be the most suitable databank for the field of psychopharmacotherapy. The best results in this comparison were achieved by MediQ but this database also needs improvement with respect to the hit rate so that the users can rely on the results and therefore increase drug therapy safety.

G6PDdb (http://www.rubic.rdg.ac.uk/g6pd/ or http://www.bioinf.org.uk/g6pd/) is a newly created web-accessible locus-specific mutation database for the human Glucose-6-phosphate dehydrogenase (G6PD) gene. The relational database integrates up-to-date mutational and structural data from various databanks (GenBank, Protein Data Bank, etc.) with biochemically characterized variants and their associated phenotypes obtained from published literature and the Favism website. An automated analysis of the mutations likely to have a significant impact on the structure of the protein has been performed using a recently developed procedure. The database may be queried online and the full results of the analysis of the structural impact of mutations are available. The web page provides a form for submitting additional mutation data and is linked to resources such as the Favism website, OMIM, HGMD, HGVBASE, and the PDB. This database provides insights into the molecular aspects and clinical significance of G6PD deficiency for researchers and clinicians and the web page functions as a knowledge base relevant to the understanding of G6PD deficiency and its management.

MetReS (Metabolic Reconstruction Server) is a genomic database that is shared between two software applications that address important biological problems. Biblio-MetReS is a data-mining tool that enables the reconstruction of molecular networks based on automated text-mining analysis of published scientific literature. Homol-MetReS allows functional (re)annotation of proteomes, to properly identify both the individual proteins involved in the processes of interest and their function. The main goal of this work was to identify the areas where the performance of the MetReS database performance could be improved and to test whether this improvement would scale to larger datasets and more complex types of analysis. The study was started with a relational database, MySQL, which is the current database server used by the applications. We also tested the performance of an alternative data-handling framework, Apache Hadoop. Hadoop is currently used for large-scale data processing. We found that this data handling framework is likely to greatly improve the efficiency of the MetReS applications as the dataset and the processing needs increase by several orders of magnitude, as expected to happen in the near future.

The Melanoma Gene Database (MGDB) is a manually curated catalog of molecular genetic data relating to genes involved in melanoma. The main purpose of this database is to establish a network of melanoma related genes and to facilitate the mechanistic study of melanoma tumorigenesis. The entries describing the relationships between melanoma and genes in the current release were manually extracted from PubMed abstracts, which contains cumulative to date 527 human melanoma genes (422 protein-coding and 105 non-coding genes). Each melanoma gene was annotated in seven different aspects (General Information, Expression, Methylation, Mutation, Interaction, Pathway and Drug). In addition, manually curated literature references have also been provided to support the inclusion of the gene in MGDB and establish its association with melanoma. MGDB has a user-friendly web interface with multiple browse and search functions. We hoped MGDB will enrich our knowledge about melanoma genetics and serve as a useful complement to the existing public resources.

Regulation of nuclear mRNA export or retention is carried out by RNA elements but the mechanism is not yet well understood. To understand the mRNA export process, it is important to collect all the involved RNA elements and their trans-acting factors. By hand-curated literature screening we collected, in ExportAid database, experimentally assessed data about RNA elements regulating nuclear export or retention of endogenous, heterologous or artificial RNAs in mammalian cells. This database could help to understand the RNA export language and to study the possible export efficiency alterations owing to mutations or polymorphisms. Currently, ExportAid stores 235 and 96 RNA elements, respectively, increasing and decreasing export efficiency, and 98 neutral assessed sequences. Freely accessible without registration at http://www.introni.it/ExportAid/ExportAid.html.

Chronic non-communicable diseases (NCDs) account for a high burden of mortality and morbidity in Africa. Evidence-based clinical guidelines recommend exercise training and promotion of physical activity behaviour changes to control NCDs. Developing such interventions in Africa requires an understanding of the essential components that make them effective in this context. This is a protocol for a systematic mixed studies review that aims to determine the effective components of exercise and physical activity-related behaviour-change interventions for chronic diseases in Africa, by combining quantitative and qualitative research evidence from studies published until July 2015. We will conduct a detailed search to identify all published and unpublished studies that assessed the effects of exercise and physical activity-related interventions or the experiences/perspectives of patients to these interventions for NCDs from bibliographic databases and the grey literature. Bibliographic databases include MEDLINE, EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), PsycINFO, CINAHL and Web of Science. We will include the following African regional databases: African Index Medicus (AIM) and AFROLIB, which is the WHO's regional office database for Africa. The databases will be searched from inception until 18 July 2015. Appraisal of study quality will be performed after results synthesis. Data synthesis will be performed independently for quantitative and qualitative data using a mixed methods sequential explanatory synthesis for systematic mixed studies reviews. Meta-analysis will be conducted for the quantitative studies, and thematic synthesis for qualitative studies and qualitative results from the non-controlled observational studies. The primary outcome will include exercise adherence and physical activity behaviour changes. This review protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. There is no ethical requirement for this study, as it utilises published data. This review is expected to inform the development of exercise and physical activity-related behaviour-change interventions in Africa, and will be presented at conferences, and published in peer reviewed journals and a PhD thesis at King's College London. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 22 January 2015 (registration number: PROSPERO 2015: CRD42015016084).

Objectives: Occupational exposure assessment for population-based case–control studies is challenging due to the wide variety of industries and occupations encountered by study participants. We developed and evaluated statistical models to estimate the intensity of exposure to three chlorinated solvents—methylene chloride, 1,1,1-trichloroethane, and trichloroethylene—using a database of air measurement data and associated exposure determinants. Methods: A measurement database was developed after an extensive review of the published industrial hygiene literature. The database of nearly 3000 measurements or summary measurements included sample size, measurement characteristics (year, duration, and type), and several potential exposure determinants associated with the measurements: mechanism of release (e.g. evaporation), process condition, temperature, usage rate, type of ventilation, location, presence of a confined space, and proximity to the source. The natural log-transformed measurement levels in the exposure database were modeled as a function of the measurement characteristics and exposure determinants using maximum likelihood methods. Assuming a single lognormal distribution of the measurements, an arithmetic mean exposure intensity level was estimated for each unique combination of exposure determinants and decade. Results: The proportions of variability in the measurement data explained by the modeled measurement characteristics and exposure determinants were 36, 38, and 54% for methylene chloride, 1,1,1-trichloroethane, and trichloroethylene, respectively. Model parameter estimates for the exposure determinants were in the anticipated direction. Exposure intensity estimates were plausible and exhibited internal consistency, but the ability to evaluate validity was limited. Conclusions: These prediction models can be used to estimate chlorinated solvent exposure intensity for jobs reported by population-based case–control study participants that have sufficiently detailed information regarding the exposure determinants.

Epilepsy is a common neurologic disorder requiring continued treatment during pregnancy. Treatment with antiepileptic drugs (AEDs) is needed for seizure control, but the risk of adverse events has to be minimized for both mother and foetus. Available data on pregnancy and foetal/postnatal outcomes following eslicarbazepine acetate (ESL) exposure via parent is herein presented for the first time. ESL's global safety database was reviewed to identify pregnancy cases with exposure to ESL reported up to October 21st, 2017. The EMBASE™ and MEDLINE ® databases were searched to identify literature reports of such cases published between May 1st, 2009 and October 21st, 2017. Overall, 91 notifications of pregnancy were identified, of which 79 involved ESL exposure: 28 during clinical trials and 51 from 8-years of post-marketing surveillance. Thirty pregnancies resulted in live birth without congenital anomalies; in 25 pregnancies the outcome was ongoing and 3 was unknown; 18 cases resulted in abortion (10 spontaneous and 8 induced) and congenital anomalies were identified in 5 cases (no clear relationship with ESL was established). ESL was used concomitantly to other AEDs in 11 of the 15 pregnancies for which the outcome was spontaneous abortion and congenital anomaly. Literature review did not yield additional information. Available data are insufficient to draw conclusions regarding ESL use during pregnancy. Although no particular safety problem was identified, ESL exposure during pregnancy will continue to be monitored and evaluated. Copyright © 2018 The Authors. Published by Elsevier Ltd..

2015-09-01

Breast cancer is the most common female cancer worldwide including India, where advanced stages at diagnosis, and rising incidence and mortality rates, make it essential to understand cancer literacy in women. We conducted a literature review to evaluate the awareness levels of risk factors for breast cancer among Indian women and health professionals. A structured literature search using combined keywords was undertaken on bibliographic databases including MEDLINE, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health (CINAHL) and SCOPUS. Searches were restricted to research published in English language peer-reviewed journals through December, 2014 in India. A total of 7066 women aged 15-70 years showed varied levels of awareness on risk factors such as family history (13-58%), reproductive history (1-88%) and obesity (11-51%). Literacy levels on risk factors did not improve over the 8-year period (2005-2013). On average, nurses reported higher, though still varied, awareness levels for risk factors such as family history (40.8-98%), reproductive history (21-90%) and obesity (34-6%). Awareness levels were not consistently higher for the stronger determinants of risk. Our review revealed low cancer literacy of breast cancer risk factors among Indian women, irrespective of their socio-economic and educational background. There is an urgent need for nation- and state-wide awareness programmes, engaging multiple stakeholders of society and the health system, to help improve cancer literacy in India.

Genetic sex determination assays in 53 mammalian species: Literature analysis and guidelines for reporting standardization.

PubMed

Hrovatin, Karin; Kunej, Tanja

2018-01-01

Erstwhile, sex was determined by observation, which is not always feasible. Nowadays, genetic methods are prevailing due to their accuracy, simplicity, low costs, and time-efficiency. However, there is no comprehensive review enabling overview and development of the field. The studies are heterogeneous, lacking a standardized reporting strategy. Therefore, our aim was to collect genetic sexing assays for mammals and assemble them in a catalogue with unified terminology. Publications were extracted from online databases using key words such as sexing and molecular. The collected data were supplemented with species and gene IDs and the type of sex-specific sequence variant (SSSV). We developed a catalogue and graphic presentation of diagnostic tests for molecular sex determination of mammals, based on 58 papers published from 2/1991 to 10/2016. The catalogue consists of five categories: species, genes, SSSVs, methods, and references. Based on the analysis of published literature, we propose minimal requirements for reporting, consisting of: species scientific name and ID, genetic sequence with name and ID, SSSV, methodology, genomic coordinates (e.g., restriction sites, SSSVs), amplification system, and description of detected amplicon and controls. The present study summarizes vast knowledge that has up to now been scattered across databases, representing the first step toward standardization regarding molecular sexing, enabling a better overview of existing tests and facilitating planned designs of novel tests. The project is ongoing; collecting additional publications, optimizing field development, and standardizing data presentation are needed.

"Can Breast Feeding Help You in Later Life? Evidence from German Military Heights in the Early 20th Century"*

PubMed Central

Haines, Michael R.; Kintner, Hallie J.

2008-01-01

Considerable literature exists on the benefits of breast feeding on the health and survival of infants and young children, but there is less on the effects on later life outcomes. One such measure of health and well-being that has received attention in the historical literature is terminal adult stature. Information on height is rather widely available; however, it is much more difficult to obtain data on breast feeding. One country that does have such information is Imperial Germany (1871–1919). A number of physicians and local health officials collected information on the incidence and duration of breast feeding early in the 20th century, particularly because of concern about the unusually high infant mortality rates in parts of Germany. Hallie Kintner has surveyed the published results of these studies. The information on the prevalence of breast feeding for the period 1903/10 has been inputed into a database of demographic and economic variables for the counties (Regierungsbezirke) of Germany (1850–1939) There are also published data on heights of military recruits from the Imperial German military forces in 1906. These can be linked to areas in the database and related to breast feeding practices and infant mortality both contemporaneously and approximately 20 years previous to 1906. Results indicate a significant effect of infant feeding practices on later life outcomes operating through infant health conditions, proxied by the infant mortality rate. PMID:18715833

To assess the methodological quality of systematic reviews and meta-analyses regarding acupuncture intervention for stroke and the primary studies within them. Two researchers searched PubMed, Cumulative index to Nursing and Allied Health Literature, Embase, ISI Web of Knowledge, Cochrane, Allied and Complementary Medicine, Ovid Medline, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang and Traditional Chinese Medical Database to identify systematic reviews and meta-analyses about acupuncture for stroke published from the inception to December 2016. Review characteristics and the criteria for assessing the primary studies within reviews were extracted. The methodological quality of the reviews was assessed using adapted Oxman and Guyatt Scale. The methodological quality of primary studies was also assessed. Thirty-two eligible reviews were identified, 15 in English and 17 in Chinese. The English reviews were scored higher than the Chinese reviews (P=0.025), especially in criteria for avoiding bias and the scope of search. All reviews used the quality criteria to evaluate the methodological quality of primary studies, but some criteria were not comprehensive. The primary studies, in particular the Chinese reviews, had problems with randomization, allocation concealment, blinding, dropouts and withdrawals, intent-to-treat analysis and adverse events. Important methodological flaws were found in Chinese systematic reviews and primary studies. It was necessary to improve the methodological quality and reporting quality of both the systematic reviews published in China and primary studies on acupuncture for stroke.

Substance abuse treatment in persons with HIV/AIDS: challenges in managing triple diagnosis.

PubMed

Durvasula, Ramani; Miller, Theodore R

2014-01-01

Clinical management of HIV must account for the "triple diagnosis" of HIV, psychiatric diagnosis, and substance use disorders and requires integrated treatment services that focus beyond just mitigation of substance use and psychiatric and medical symptoms but also address other health behaviors. Because clinical management of HIV/AIDS has shifted significantly with the advent of highly active antiretroviral therapies (HAART) in the mid 1990s, a literature review focusing on literature published since 2000, and using relevant key words was conducted using a wide range of literature search databases. This literature review was complemented by studies to expand on specific treatment modalities for which there was a dearth of literature addressing HIV infected cohorts and to provide discussion of issues around substance abuse treatment as an HIV prevention tool. Existing models of substance abuse treatment including cognitive behavioral therapy and motivational interviewing have proven to be useful for enhancing adherence and reducing substance use in outpatient populations, while methadone maintenance and directly observed treatment have been useful with specific subgroups of users. Contextualization of services heightens the likelihood of successful outcomes and relapse prevention.

Oral health-related cultural beliefs for four racial/ethnic groups: Assessment of the literature

PubMed Central

Butani, Yogita; Weintraub, Jane A; Barker, Judith C

2008-01-01

Background The purpose of this study was to assess information available in the dental literature on oral health-related cultural beliefs. In the US, as elsewhere, many racial/ethnic minority groups shoulder a disproportionate burden of oral disease. Cultural beliefs, values and practices are often implicated as causes of oral health disparities, yet little is known about the breadth or adequacy of literature about cultural issues that could support these assertions. Hence, this rigorous assessment was conducted of work published in English on cultural beliefs and values in relation to oral health status and dental practice. Four racial/ethnic groups in the US (African-American, Chinese, Filipino and Hispanic/Latino) were chosen as exemplar populations. Methods The dental literature published in English for the period 1980–2006 noted in the electronic database PUBMED was searched, using keywords and MeSH headings in different combinations for each racial/ethnic group to identify eligible articles. To be eligible the title and abstract when available had to describe the oral health-related cultural knowledge or orientation of the populations studied. Results Overall, the majority of the literature on racial/ethnic groups was epidemiologic in nature, mainly demonstrating disparities in oral health rather than the oral beliefs or practices of these groups. A total of 60 relevant articles were found: 16 for African-American, 30 for Chinese, 2 for Filipino and 12 for Hispanic/Latino populations. Data on beliefs and practices from these studies has been abstracted, compiled and assessed. Few research-based studies were located. Articles lacked adequate identification of groups studied, used limited methods and had poor conceptual base. Conclusion The scant information available from the published dental and medical literature provides at best a rudimentary framework of oral health related ideas and beliefs for specific populations.

Stuttering is a disorder that affects millions of people all over the world. Over the past two decades, there has been a great deal of interest in investigating the neural basis of the disorder. This systematic literature review is intended to provide a comprehensive summary of the neuroimaging literature on developmental stuttering. It is a resource for researchers to quickly and easily identify relevant studies for their areas of interest and enable them to determine the most appropriate methodology to utilize in their work. The review also highlights gaps in the literature in terms of methodology and areas of research. We conducted a systematic literature review on neuroimaging studies on developmental stuttering according to the PRISMA guidelines. We searched for articles in the pubmed database containing "stuttering" OR "stammering" AND either "MRI", "PET", "EEG", "MEG", "TMS"or "brain" that were published between 1995/​01/​01 and 2016/​01/​01. The search returned a total of 359 items with an additional 26 identified from a manual search. Of these, there were a total of 111 full text articles that met criteria for inclusion in the systematic literature review. We also discuss neuroimaging studies on developmental stuttering published throughout 2016. The discussion of the results is organized first by methodology and second by population (i.e., adults or children) and includes tables that contain all items returned by the search. There are widespread abnormalities in the structural architecture and functional organization of the brains of adults and children who stutter. These are evident not only in speech tasks, but also non-speech tasks. Future research should make greater use of functional neuroimaging and noninvasive brain stimulation, and employ structural methodologies that have greater sensitivity. Newly planned studies should also investigate sex differences, focus on augmenting treatment, examine moments of dysfluency and longitudinally or cross-sectionally investigate developmental trajectories in stuttering.

Several cases of hearing loss induced by hydroxychloroquine have been reported in the literature but the role of hydroxychloroquine still remains debated. We report the first case, to our knowledge, of hearing loss induced by hydroxychloroquine with a positive re challenge in a woman treated for systemic lupus. An analysis of the French pharmacovigilance database allowed to identify 23 additional cases of hearing loss in patients treated with hydroxychloroquine and, among them, 8 had systemic lupus. Despite an excellent tolerance and high efficacy-side effect ratio, this case report adds some evidence for an otoxicity of hydroxychloroquine.

2010-02-01

The objective of this study was to find out the number of publications (in Danish) and research projects (including grey literature) either carried out or ongoing within the field of public health in Denmark, using the same criteria as the SPHERE project, but looking at Danish research databases. The Danish research database served as the main resource for the study supported by national research reports. There is an increasing trend in the number of public health research projects and publications. Compared with public health research projects published in English there are differences in some categories. Overall, public health research in Denmark seems to contribute around 4.8%-6.5% of the total amount of health research. Public health research has a relatively low share of overall health research in Denmark.

Information prescriptions, 1930-2013: an international history and comprehensive review.

PubMed

McKnight, Michelynn

2014-10-01

Recently, government agencies in several countries have promoted information prescription programs to increase patients' understanding of their conditions. The practice has a long history and many publications, but no comprehensive literature reviews such as this. Using a variety of high-precision and high-recall strategies, the researcher searched two dozen online bibliographic databases, citation databases, and repositories, as well as many print sources, to identify and retrieve documents for review. Of these documents, ninety relevant English-language case reports, research reports, and reviews published from 1930-2013 met the study criteria. Early to mid-twentieth century reports covered long-standing practices and used no rigorous research methods. The literature since the mid-1990s reports on short-term trial projects, especially of government-sponsored programs in the United States and United Kingdom. Although the concept of information prescription has been in the literature and practiced for decades, no long-term research studies were found. Most of the literature is anecdotal concerning small pilot projects. The reports investigate physician, patient, and librarian satisfaction but not changes in patient knowledge or behavior. Many twenty-first century projects emphasize materials and projects from specific government agencies and commercial enterprises. While the practice is commonly believed to be a good idea and there are many publications on the subject, few studies provide any evidence of the efficacy of information prescriptions for increased patient knowledge. Well-designed and executed large or long-term studies might produce needed evidence for professional practice.

Effective mentoring is an invaluable element in the development of next generation of neurosurgeons. A mentor helps to develop professional core values, technical and non-technical skills, attitudes and disposition required to be qualified and competent neurosurgeon. Giving the invaluable significance of mentoring in neurosurgery, we undertook this literature review to identify mentoring models evaluating its success and relative benefit. Literature search identified using MeSH word 'mentor', mentoring, mentorship, mentoring model, neurosurgery' in MEDLINE, EMBASE and Scopus databases from 1990 to 2016. Literature reviewed to identify status of mentoring in neurosurgery, potential barriers, pitfalls and future framework for mentoring in neurosurgery. Additional articles identified through manual search of reference lists. A total of 247 studies were obtained from electronic databases, after removing duplicates, abstracts, letters to the editor and non-neurosurgery papers. Sixteen full text articles retrieved out of which five met the inclusion criteria. Generally, there is paucity of articles regarding mentoring in neurosurgery, all included papers were written in English Language, all of them described mentoring model used including simulation, distance, collaborative, facilitative tele-mentoring and peer mentoring. Mentoring in Neurosurgery is an important aspect of personal and professional development of neurosurgical trainees, currently there is decline in traditional apprenticeship due to increase demand for modern use of specialised technology, simulation and tele-medicine in neurosurgery practice. Effective and efficient mentoring will be an interplay of six mentoring models (collaborative, facilitative, distance, simulation, tele mentoring and peer mentoring) identified.

To determine the optimal databases to search for studies of faith-sensitive interventions for treating depression. We examined 23 health, social science, religious, and grey literature databases searched for an evidence synthesis. Databases were prioritized by yield of (1) search results, (2) potentially relevant references identified during screening, (3) included references contained in the synthesis, and (4) included references that were available in the database. We assessed the impact of databases beyond MEDLINE, EMBASE, and PsycINFO by their ability to supply studies identifying new themes and issues. We identified pragmatic workload factors that influence database selection. PsycINFO was the best performing database within all priority lists. ArabPsyNet, CINAHL, Dissertations and Theses, EMBASE, Global Health, Health Management Information Consortium, MEDLINE, PsycINFO, and Sociological Abstracts were essential for our searches to retrieve the included references. Citation tracking activities and the personal library of one of the research teams made significant contributions of unique, relevant references. Religion studies databases (Am Theo Lib Assoc, FRANCIS) did not provide unique, relevant references. Literature searches for reviews and evidence syntheses of religion and health studies should include social science, grey literature, non-Western databases, personal libraries, and citation tracking activities.

Indians, representing about one-sixth of the world population, consist of several thousands of endogamous groups with strong potential for excess of recessive diseases. However, no database is available on Indian population with comprehensive information on the diseases common in the country. To address this issue, we present Indian Genetic Disease Database (IGDD) release 1.0 (http://www.igdd.iicb.res.in)—an integrated and curated repository of growing number of mutation data on common genetic diseases afflicting the Indian populations. Currently the database covers 52 diseases with information on 5760 individuals carrying the mutant alleles of causal genes. Information on locus heterogeneity, type of mutation, clinical and biochemical data, geographical location and common mutations are furnished based on published literature. The database is currently designed to work best with Internet Explorer 8 (optimal resolution 1440 × 900) and it can be searched based on disease of interest, causal gene, type of mutation and geographical location of the patients or carriers. Provisions have been made for deposition of new data and logistics for regular updation of the database. The IGDD web portal, planned to be made freely available, contains user-friendly interfaces and is expected to be highly useful to the geneticists, clinicians, biologists and patient support groups of various genetic diseases.

The meta-analysis is regarded as an important evidence for making scientific decision. The database of ISI Web of Science collected a great number of high quality literatures including meta-analysis literatures. However, it is significant to understand the general characteristics of meta-analysis literatures to outline the perspective of meta-analysis. In this present study, we summarized and clarified some features on these literatures in the database of ISI Web of Science. We retrieved the meta-analysis literatures in the database of ISI Web of Science including SCI-E, SSCI, A&HCI, CPCI-S, CPCI-SSH, CCR-E, and IC. The annual growth rate, literature category, language, funding, index citation, agencies and countries/territories of the meta-analysis literatures were analyzed, respectively. A total of 95,719 records, which account for 0.38% (99% CI: 0.38%-0.39%) of all literatures, were found in the database. From 1997 to 2012, the annual growth rate of meta-analysis literatures was 18.18%. The literatures involved in many categories, languages, fundings, citations, publication agencies, and countries/territories. Interestingly, the index citation frequencies of the meta-analysis were significantly higher than that of other type literatures such as multi-centre study, randomize controlled trial, cohort study, case control study, and cases report (P<0.0001). The increasing numbers, intensively global influence and high citations revealed that the meta-analysis has been becoming more and more prominent in recent years. In future, in order to promote the validity of meta-analysis, the CONSORT and PRISMA standard should be continuously popularized in the field of evidence-based medicine.

High-intensity focused ultrasound (HIFU) is a highly precise medical procedure used locally to heat and destroy diseased tissue through ablation. This study intended to review HIFU in uterine fibroid therapy, to evaluate the role of HIFU in the therapy of leiomyomas as well as to review the actual clinical activities in this field including efficacy and safety measures beside the published clinical literature. An inclusive literature review was carried out in order to review the scientific foundation, and how it resulted in the development of extracorporeal distinct devices. Studies addressing HIFU in leiomyomas were identified from a search of the Internet scientific databases. The analysis of literature was limited to journal articles written in English and published between 2000 and 2013. In current gynecologic oncology, HIFU is used clinically in the treatment of leiomyomas. Clinical research on HIFU therapy for leiomyomas began in the 1990s, and the majority of patients with leiomyomas were treated predominantly with HIFUNIT 9000 and prototype single focus ultrasound devices. HIFU is a non-invasive and highly effective standard treatment with a large indication range for all sizes of leiomyomas, associated with high efficacy, low operative morbidity and no systemic side effects. Uterine fibroid treatment using HIFU was effective and safe in treating symptomatic uterine fibroids. Few studies are available in the literature regarding uterine artery embolization (UAE). HIFU provides an excellent option to treat uterine fibroids.

The Wind-Wildlife Impacts Literature Database (WILD), formerly known as the Avian Literature Database, was created in 1997. The goal of the database was to begin tracking the research that detailed the potential impact of wind energy development on birds. The Avian Literature Database was originally housed on a proprietary platform called Livelink ECM from Open- Text and maintained by in-house technical staff. The initial set of records was added by library staff. A vital part of the newly launched Drupal-based WILD database is the Bibliography module. Many of the resources included in the database have digital object identifiers (DOI). Themore » bibliographic information for any item that has a DOI can be imported into the database using this module. This greatly reduces the amount of manual data entry required to add records to the database. The content available in WILD is international in scope, which can be easily discerned by looking at the tags available in the browse menu.« less

Telescope Bibliography Cookbook: Creating a Database of Scientific Papers that Use Observational Data

NASA Astrophysics Data System (ADS)

Kitt, S.; Grothkopf, U.

2010-10-01

This paper explains the procedures involved in creating a database of scientific papers that use observational data and linking the records to the observations residing in a data archive. Based on our experiences with the ESO Telescope Bibliography, we describe the workflow we apply in order to retrieve relevant articles, assign tags to describe the observing facilities that generated the data, and identify the correct program identification numbers (IDs). These program identifiers are particularly important as they link the published papers and the underlying data and enable scientists to access the data for new studies. With the understanding that the difficulty of compiling correct and complete data varies, depending on the information readily provided in the published literature, this paper proposes an evolution of search options for finding appropriate ID numbers. To explore the process and its various stages, we use the analogy of the "cookbook." These search methodologies might be labeled fast, medium, and slow heat recipes within our culinary theme. We provide a step-by-step guide in order to assist other bibliography compilers, in particular those who are new to the field.

To analyze the frequency of psychiatric comorbidities in patients with systemic lupus erythematosus (SLE) using the systematic review method. A systematic literature search was performed between April and July 2011 in the following databases: BIREME, PubMed and CAPES thesis database. This search prioritized studies published over the last ten years (2001-2011), involving the presence of psychiatric comorbidities in patients with SLE. Out of 314 articles published in scientific journals (PubMed) and 29 (BIREME), previously identified ones, 13 articles on psychiatric disorders and SLE were selected so they could be submitted to the systematic review methodological approach. The articles indicated high frequency of psychiatric comorbidities, especially mood and anxiety disorders. There is no consensus between the disease activity and psychiatric disorders. Patients with active SLE showed a higher risk of developing mood disorders than patients with inactive SLE. Patients with SLE had a higher suicide risk than the general population. More thorough studies to evaluate the psychological and genetic role, specific and non-specific autoimmune inflammatory mechanisms in mood and anxiety disorders are needed.

Much of the data within Model Organism Databases (MODs) comes from manual curation of the primary research literature. Given limited funding and an increasing density of published material, a significant challenge facing all MODs is how to efficiently and effectively prioritize the most relevant research papers for detailed curation. Here, we report recent improvements to the triaging process used by FlyBase. We describe an automated method to directly e-mail corresponding authors of new papers, requesting that they list the genes studied and indicate (‘flag’) the types of data described in the paper using an online tool. Based on the author-assigned flags, papers are then prioritized for detailed curation and channelled to appropriate curator teams for full data extraction. The overall response rate has been 44% and the flagging of data types by authors is sufficiently accurate for effective prioritization of papers. In summary, we have established a sustainable community curation program, with the result that FlyBase curators now spend less time triaging and can devote more effort to the specialized task of detailed data extraction.

Glycan structures attached to proteins are comprised of diverse monosaccharide sequences and linkages that are produced from precursor nucleotide-sugars by a series of glycosyltransferases. Databases of these structures are an essential resource for the interpretation of analytical data and the development of bioinformatics tools. However, with no template to predict what structures are possible the human glycan structure databases are incomplete and rely heavily on the curation of published, experimentally determined, glycan structure data. In this work, a library of 45 human glycosyltransferases was used to generate a theoretical database of N-glycan structures comprised of 15 or less monosaccharide residues. Enzyme specificities were sourced from major online databases including Kyoto Encyclopedia of Genes and Genomes (KEGG) Glycan, Consortium for Functional Glycomics (CFG), Carbohydrate-Active enZymes (CAZy), GlycoGene DataBase (GGDB) and BRENDA. Based on the known activities, more than 1.1 million theoretical structures and 4.7 million synthetic reactions were generated and stored in our database called UniCorn. Furthermore, we analyzed the differences between the predicted glycan structures in UniCorn and those contained in UniCarbKB (www.unicarbkb.org), a database which stores experimentally described glycan structures reported in the literature, and demonstrate that UniCorn can be used to aid in the assignment of ambiguous structures whilst also serving as a discovery database.

Research by retrieving experiments.

Newton did not discover that apples fall: the information was available prior to his gravitational hypothesis. Hypotheses can be tested not only by performing experiments but also by retrieving experiments from the literature (via PubMed, for example). Here I show how disconnected facts from known data, if properly connected, can generate novel predictions testable in turn by other published data. With examples from cell cycle, aging, cancer and other fields of biology and medicine, I discuss how new knowledge was and will be derived from old information. Millions of experiments have been already performed to test unrelated hypotheses and the results of those experiments are available to 'test' your hypotheses too. But most data (99% by some estimates) remain unpublished, because they were negative, seemed of low priority, or did not fit the story. Yet for other investigators those data may be valuable. The well-known story of Franklin and Watson is a case in point. By making preliminary data widely available, 'data-owners' will benefit most, receiving the credit for otherwise unused results. If posted (pre-published) on searchable databases, these data may fuel thousands of projects without the need for repetitive experiments. Enormous 'pre-published' databases coupled with Google-like search engines can change the structure of scientific research, and shrinking funding will make this inevitable.

Purpose: Dose inhomogeneity in treatment planning can be compensated using physical wedges. Enhanced dynamic wedges (EDW) were introduced by Varian to overcome some of the short comings of physical wedges. The objectives of this study were to measure EDW output factors for 6 MV and 20 MV photon energies for a Varian 2300CD. Secondly to review the literature in terms of published enhanced dynamic wedge output factors (EDWOF) for different Varian models and thereby adding credence to the case of the validity of reference databases. Methods: The enhanced dynamic wedge output factors were measured for the Varian 2300CD for bothmore » 6 MV and 20 MV photon energies. Twelve papers with published EDWOF for different Varian Linac models were found in the literature. Results: The EDWOF for 6 MV varied from 0.980 for a 5×5 cm 10 degree wedge to 0.424 for 20×20 cm 60 degree wedge. Similarly for 20 MV, the EDWOF varied from 0.986 for 5×5 cm 10 degree wedge to 0.529 for 20×20 cm 60 degree wedge. EDWOF are highly dependent on field size. Comparing our results with the published mean, we found an excellent agreement for 6 MV EDWOF with the percentage differences ranging from 0.01% to 0.57% with a mean of 0.03%. The coefficient of variation of published EDWOF ranged from 0.17% to 0.85% and 0.1% to 0.9% for the for 6 MV and 18MV photon energies respectively. This paper provides the first published EDWOF for 20 MV photon energy. In addition, we have provided the first compendium of EDWOFs for different Varian linac models. Conclusion: The consistency of EDWOF across models and institution provide further support that, a standard data set of basic photon and electron dosimetry could be established, as a guide for future commissioning, beam modeling and quality assurance purposes.« less

Literature databases are an ever-expanding resource available to the field of medical sciences. Understanding how to use such databases efficiently is critical for those involved in research. However, for the uninitiated, getting started is a major hurdle to overcome and for the occasional user, the finer points of database searching remain an unacquired skill. In the fifth and final article in this series aimed at those embarking on ophthalmology and vision science research, we look at how the beginning researcher can start to use literature databases and, by using a stepwise approach, how they can optimize their use. This instructional paper gives a hypothetical example of a researcher writing a review article and how he or she acquires the necessary scientific literature for the article. A prototype search of the Medline database is used to illustrate how even a novice might swiftly acquire the skills required for a medium-level search. It provides examples and key tips that can increase the proficiency of the occasional user. Pitfalls of database searching are discussed, as are the limitations of which the user should be aware.

In plants, various phloem-mobile macromolecules including noncoding RNAs, mRNAs and proteins are suggested to act as important long-distance signals in regulating crucial physiological and morphological transition processes such as flowering, plant growth and stress responses. Given recent advances in high-throughput sequencing technologies, numerous mobile macromolecules have been identified in diverse plant species from different plant families. However, most of the identified mobile macromolecules are not annotated in current versions of species-specific databases and are only available as non-searchable datasheets. To facilitate study of the mobile signaling macromolecules, we compiled the PlaMoM (Plant Mobile Macromolecules) database, a resource that provides convenient and interactive search tools allowing users to retrieve, to analyze and also to predict mobile RNAs/proteins. Each entry in the PlaMoM contains detailed information such as nucleotide/amino acid sequences, ortholog partners, related experiments, gene functions and literature. For the model plant Arabidopsis thaliana, protein–protein interactions of mobile transcripts are presented as interactive molecular networks. Furthermore, PlaMoM provides a built-in tool to identify potential RNA mobility signals such as tRNA-like structures. The current version of PlaMoM compiles a total of 17 991 mobile macromolecules from 14 plant species/ecotypes from published data and literature. PlaMoM is available at http://www.systembioinfo.org/plamom/. PMID:27924044

The aim of this meta-analysis was to assess the effectiveness of evidence-based nursing (EBN) on the development of critical thinking for nursing students. A systematic literature review of original studies on randomized controlled trials was conducted. The relevant randomized controlled trials were retrieved from multiple electronic databases including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), Chinese BioMed Database (CBM), China National Knowledge Infrastructure (CNKI), and WanFang Database. In order to make a systematic evaluation, studies were selected according to inclusion and exclusion criteria, and then according to extracted data and assessed quality. The data extraction was completed by two independent reviewers, and the methodological quality assessment was completed by another two reviewers. All of the data was analyzed by the software RevMan5.3. A total of nine studies with 1079 nursing students were chosen in this systematic literature review. The result of this meta-analysis showed that the effectiveness of evidence-based nursing was superior to that of traditional teaching on nursing students' critical thinking. The results of this meta-analysis indicate that evidence-based nursing could help nursing students to promote their development of critical thinking. More researches with higher quality and larger sample size can be analyzed in the further. Copyright © 2018. Published by Elsevier Ltd.

2010-10-01

To develop search strategies for identifying papers on patient safety in MEDLINE, EMBASE and CINAHL. Six journals were electronically searched for papers on patient safety published between 2000 and 2006. Identified papers were divided into two gold standards: one to build and the other to validate the search strategies. Candidate terms for strategy construction were identified using a word frequency analysis of titles, abstracts and keywords used to index the papers in the databases. Searches were run for each one of the selected terms independently in every database. Sensitivity, precision and specificity were calculated for each candidate term. Terms with sensitivity greater than 10% were combined to form the final strategies. The search strategies developed were run against the validation gold standard to assess their performance. A final step in the validation process was to compare the performance of each strategy to those of other strategies found in the literature. We developed strategies for all three databases that were highly sensitive (range 95%-100%), precise (range 40%-60%) and balanced (the product of sensitivity and precision being in the range of 30%-40%). The strategies were very specific and outperformed those found in the literature. The strategies we developed can meet the needs of users aiming to maximise either sensitivity or precision, or seeking a reasonable compromise between sensitivity and precision, when searching for papers on patient safety in MEDLINE, EMBASE or CINAHL.

Membrane transport proteins play a crucial role in the import and export of ions, small molecules or macromolecules across biological membranes. Currently, there are a limited number of published computational tools which enable the systematic discovery and categorization of transporters prior to costly experimental validation. To approach this problem, we utilized a nearest neighbor method which seamlessly integrates homologous search and topological analysis into a machine-learning framework. Our approach satisfactorily distinguished 484 transporter families in the Transporter Classification Database, a curated and representative database for transporters. A five-fold cross-validation on the database achieved a positive classification rate of 72.3% on average. Furthermore, this method successfully detected transporters in seven model and four non-model organisms, ranging from archaean to mammalian species. A preliminary literature-based validation has cross-validated 65.8% of our predictions on the 11 organisms, including 55.9% of our predictions overlapping with 83.6% of the predicted transporters in TransportDB.

Introduction: Ureteral endometriosis is a rare disease affecting women of childbearing age which presents with nonspecific symptoms and it may result in severe morbidity. The aim of this study was to review evidence about incidence, pathogenesis, clinical presentation, diagnosis, and management of ureteral endometriosis. Materials and Methods: PubMed Central database was searched to identify studies reporting cases of ureteral endometriosis. “Ureter” or “Ureteral” and “Endometriosis” were used as key words. Database was searched for articles published since 1996, in English without restrictions regarding the study design. Results: From 420 studies obtained through database search, 104 articles were finally included in this review, including a total of 1384 patients with ureteral endometriosis. Data regarding age, location, pathological findings, and interventions were extracted. Mean patients' age was 38.6 years, whereas the therapeutic arsenal included hormonal, endoscopic, and/or surgical treatment. Conclusions: Ureteral endometriosis represents a diagnostic and therapeutic challenge for the clinicians and high clinical suspicion is needed to identify it. PMID:29021650

To perform a statistically rigorous meta-analysis of research results on the response by woody vegetation to increased atmospheric CO2 levels, a multiparameter database of responses was compiled. Eighty-four independent CO2-enrichment studies, covering 65 species and 35 response parameters, met the necessary criteria for inclusion in the database: reporting mean response, sample size, and variance of the response (either as standard deviation or standard error). Data were retrieved from the published literature and unpublished reports. This numeric data package contains a 29-field data set of CO2-exposure experiment responses by woody plants (as both a flat ASCII file and a spreadsheet file), files listing the references to the CO2-exposure experiments and specific comments relevant to the data in the data set, and this documentation file (which includes SAS and Fortran codes to read the ASCII data file; SAS is a registered trademark of the SAS Institute, Inc., Cary, North Carolina 27511).

The report examines a group of putative nongenotoxic carcinogens that have been cited in the published literature. Using short-term test data from the US Environmental Protection Agency/International Agency for Research on Cancer genetic activity profile (EPA/IARC GAP) database, these agents are classified on the basis of their mutagenicity emphasizing three genetic endpoints: gene mutation, chromosomal aberration and aneuploidy. On the basis of results of short-term tests for these effects, criteria was defined for evidence of mutagenicity (and nonmutagenicity) these criteria were applied in classifying the group of putative nongenotoxic carcinogens. The results from this evaluation based on the EPA/IARC GAPmore » database are presented along with a summary of the short-term test data for each chemical and the relevant carcinogenicity results from the NTP, Gene-Tox and IARC databases. The data clearly demonstrate that many of the putative nongenotoxic carcinogens that have been adequately tested in short-term bioassays induce gene or chromosomal mutations or aneuploidy.« less

Can UK NHS research ethics committees effectively monitor publication and outcome reporting bias?

PubMed

Begum, Rasheda; Kolstoe, Simon

2015-07-25

Publication and outcome reporting bias is often caused by researchers selectively choosing which scientific results and outcomes to publish. This behaviour is ethically significant as it distorts the literature used for future scientific or clinical decision-making. This study investigates the practicalities of using ethics applications submitted to a UK National Health Service (NHS) research ethics committee to monitor both types of reporting bias. As part of an internal audit we accessed research ethics database records for studies submitting an end of study declaration to the Hampshire A research ethics committee (formerly Southampton A) between 1st January 2010 and 31st December 2011. A literature search was used to establish the publication status of studies. Primary and secondary outcomes stated in application forms were compared with outcomes reported in publications. Out of 116 studies the literature search identified 57 publications for 37 studies giving a publication rate of 32%. Original Research Ethics Committee (REC) applications could be obtained for 28 of the published studies. Outcome inconsistencies were found in 16 (57%) of the published studies. This study showed that the problem of publication and outcome reporting bias is still significant in the UK. The method described here demonstrates that UK NHS research ethics committees are in a good position to detect such bias due to their unique access to original research protocols. Data gathered in this way could be used by the Health Research Authority to encourage higher levels of transparency in UK research.

Overweight/obesity is a problem faced by both high- and low- and middle-income countries. This review aimed to report published data on the prevalence of overweight and obesity in Indonesian children, adolescents, and adults, along with the associated risk factors. Literature review. We conducted a literature search for articles published in English (through Medline via OvidSP, Scopus, Global Health via OvidSP and Web of Science electronic databases) and Indonesian languages (several websites, direct contact with Indonesian public health researchers, practitioners and Ministry of Health staff) from earliest to March 2016. We screened the results and ensured the quality of included studies with Loney's tools for critically appraising prevalence or incidence studies. We included 17 papers on the topic which were available in full text and passed the critical appraisal process. The prevalence of overweight/obesity has increased over the past two decades in Indonesian children, adolescents and adults. Prevalence rates are higher in boys than girls among children, but higher in females in the adolescent and adult age groups. The prevalence of overweight/obesity is also higher in those living in urban areas and with higher income or education. Overweight/obesity is a serious public health problem in Indonesia with a continuing increase in its prevalence. Interventions at the household level and beyond are needed to successfully lower the prevalence of overweight/obesity in the country. Copyright © 2017 The Royal Society for Public Health.

A meta-analysis of the published literature on the effectiveness of antimicrobial soaps.

PubMed

Montville, Rebecca; Schaffner, Donald W

2011-11-01

The goal of this research was to conduct a systematic quantitative analysis of the existing data in the literature in order to determine if there is a difference between antimicrobial and nonantimicrobial soaps and to identify the methodological factors that might affect this difference. Data on hand washing efficacy and experimental conditions (sample size, wash duration, soap quantity, challenge organism, inoculum size, and neutralization method) from published studies were compiled and transferred to a relational database. A total of 25 publications, containing 374 observations, met the study selection criteria. The majority of the studies included fewer than 15 observations with each treatment and included a direct comparison between nonantimicrobial soap and antimicrobial soap. Although differences in efficacy between antimicrobial and nonantimicrobial soap were small (∼0.5-log CFU reduction difference), antimicrobial soap produced consistently statistically significantly greater reductions. This difference was true for any of the antimicrobial compounds investigated where n was >20 (chlorhexidine gluconate, iodophor, triclosan, or povidone). Average log reductions were statistically significantly greater (∼2 log CFU) when either gram-positive or gram-negative transient organisms were deliberately added to hands compared with experiments done with resident hand flora (∼0.5 log CFU). Our findings support the importance of using a high initial inoculum on the hands, well above the detection limit. The inherent variability in hand washing seen in the published literature underscores the importance of using a sufficiently large sample size to detect differences when they occur.

2010-11-28

To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM). We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA, accessed via PubMed and Google Scholar databases. Ninety-five published cases of LSAA were evaluated and a 25-year-old female, who presented to our clinic with left lower abdominal pain caused by LSAA, is reported. In the reviewed literature, fifty-seven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years. Sixty-six patients had SIT, 23 had MM, three had cecal malrotation, and two had a previously unnoted congenital abnormality. Fifty-nine patients had presented to the hospital with left lower, 14 with right lower and seven with bilateral lower quadrant pain, and seven subjects complained of left upper quadrant pain. The diagnosis was established preoperatively in 49 patients, intraoperatively in 19, and during the postoperative period in five; 14 patients were aware of having this anomaly. The data of eight patients were not unavailable. Eleven patients underwent laparoscopic appendectomy, which was combined with cholecystectomy in two cases. Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients. The diagnosis of left lower quadrant pain is based on well-established clinical symptoms, physical examination and physician's experience.

Practice guidelines reflect published literature. Because of the ever changing literature base, it is necessary to update and revise guideline recommendations from time to time. The Society of Thoracic Surgeons recommends review and possible update of previously published guidelines at least every three years. This summary is an update of the blood conservation guideline published in 2007. The search methods used in the current version differ compared to the previously published guideline. Literature searches were conducted using standardized MeSH terms from the National Library of Medicine PUBMED database list of search terms. The following terms comprised the standard baseline search terms for all topics and were connected with the logical 'OR' connector--Extracorporeal circulation (MeSH number E04.292), cardiovascular surgical procedures (MeSH number E04.100), and vascular diseases (MeSH number C14.907). Use of these broad search terms allowed specific topics to be added to the search with the logical 'AND' connector. In this 2011 guideline update, areas of major revision include: 1) management of dual anti-platelet therapy before operation, 2) use of drugs that augment red blood cell volume or limit blood loss, 3) use of blood derivatives including fresh frozen plasma, Factor XIII, leukoreduced red blood cells, platelet plasmapheresis, recombinant Factor VII, antithrombin III, and Factor IX concentrates, 4) changes in management of blood salvage, 5) use of minimally invasive procedures to limit perioperative bleeding and blood transfusion, 6) recommendations for blood conservation related to extracorporeal membrane oxygenation and cardiopulmonary perfusion, 7) use of topical hemostatic agents, and 8) new insights into the value of team interventions in blood management. Much has changed since the previously published 2007 STS blood management guidelines and this document contains new and revised recommendations. Copyright © 2011 The Society of Thoracic Surgeons.

Data Model and Relational Database Design for Highway Runoff Water-Quality Metadata

USGS Publications Warehouse

Granato, Gregory E.; Tessler, Steven

2001-01-01

A National highway and urban runoff waterquality metadatabase was developed by the U.S. Geological Survey in cooperation with the Federal Highway Administration as part of the National Highway Runoff Water-Quality Data and Methodology Synthesis (NDAMS). The database was designed to catalog available literature and to document results of the synthesis in a format that would facilitate current and future research on highway and urban runoff. This report documents the design and implementation of the NDAMS relational database, which was designed to provide a catalog of available information and the results of an assessment of the available data. All the citations and the metadata collected during the review process are presented in a stratified metadatabase that contains citations for relevant publications, abstracts (or previa), and reportreview metadata for a sample of selected reports that document results of runoff quality investigations. The database is referred to as a metadatabase because it contains information about available data sets rather than a record of the original data. The database contains the metadata needed to evaluate and characterize how valid, current, complete, comparable, and technically defensible published and available information may be when evaluated for application to the different dataquality objectives as defined by decision makers. This database is a relational database, in that all information is ultimately linked to a given citation in the catalog of available reports. The main database file contains 86 tables consisting of 29 data tables, 11 association tables, and 46 domain tables. The data tables all link to a particular citation, and each data table is focused on one aspect of the information collected in the literature search and the evaluation of available information. This database is implemented in the Microsoft (MS) Access database software because it is widely used within and outside of government and is familiar to many existing and potential customers. The stratified metadatabase design for the NDAMS program is presented in the MS Access file DBDESIGN.mdb and documented with a data dictionary in the NDAMS_DD.mdb file recorded on the CD-ROM. The data dictionary file includes complete documentation of the table names, table descriptions, and information about each of the 419 fields in the database.

Comparison of tiered formularies and reference pricing policies: a systematic review

PubMed Central

Morgan, Steve; Hanley, Gillian; Greyson, Devon

2009-01-01

Objectives To synthesize methodologically comparable evidence from the published literature regarding the outcomes of tiered formularies and therapeutic reference pricing of prescription drugs. Methods We searched the following electronic databases: ABI/Inform, CINAHL, Clinical Evidence, Digital Dissertations & Theses, Evidence-Based Medicine Reviews (which incorporates ACP Journal Club, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Database of Abstracts of Reviews of Effectiveness, Health Technology Assessments and NHS Economic Evaluation Database), EconLit, EMBASE, International Pharmaceutical Abstracts, MEDLINE, PAIS International and PAIS Archive, and the Web of Science. We also searched the reference lists of relevant articles and several grey literature sources. We sought English-language studies published from 1986 to 2007 that examined the effects of either therapeutic reference pricing or tiered formularies, reported on outcomes relevant to patient care and cost-effectiveness, and employed quantitative study designs that included concurrent or historical comparison groups. We abstracted and assessed potentially appropriate articles using a modified version of the data abstraction form developed by the Cochrane Effective Practice and Organisation of Care Group. Results From an initial list of 2964 citations, 12 citations (representing 11 studies) were deemed eligible for inclusion in our review: 3 studies (reported in 4 articles) of reference pricing and 8 studies of tiered formularies. The introduction of reference pricing was associated with reduced plan spending, switching to preferred medicines, reduced overall drug utilization and short-term increases in the use of physician services. Reference pricing was not associated with adverse health impacts. The introduction of tiered formularies was associated with reduced plan expenditures, greater patient costs and increased rates of non-compliance with prescribed drug therapy. From the data available, we were unable to examine the hypothesis that tiered formulary policies result in greater use of physician services and potentially worse health outcomes. Conclusion The available evidence does not clearly differentiate between reference pricing and tiered formularies in terms of policy outcomes. Reference pricing appears to have a slight evidentiary advantage, given that patients’ health outcomes under tiered formularies have not been well studied and that tiered formularies are associated with increased rates of medicine discontinuation.

2010-11-01

Concomitant use of anticancer drugs (ACDs) and antidepressants (ADs) in the treatment of depression in patients with cancer may result in potentially harmful drug-drug interactions (DDIs). It is crucial that clinicians make timely, accurate, safe and effective decisions regarding drug therapies in patients. The ubiquitous nature of the internet or "cloud" has enabled easy dissemination of DDI information, but there is currently no database dedicated to allow searching of ACD interactions by chemotherapy regimens. We describe the implementation of an AD interaction module to a previously published oncology-specific DDI database for clinicians which focuses on ACDs, single-agent and multiple-agent chemotherapy regimens. Drug- and DDI-related information were collated from drug information handbooks, databases, package inserts, and published literature from PubMed, Scopus and Science Direct. Web documents were constructed using Adobe software and programming scripts, and mounted on a domain served from the internet cloud. OncoRx is an oncology-specific DDI database whose structure is designed around all the major classes of ACDs and their frequently prescribed chemotherapy regimens. There are 117 ACDs and 256 regimens in OncoRx, and it can detect over 1 500 interactions with 21 ADs. Clinicians are provided with the pharmacokinetic parameters of the drugs, information on the regimens and details of the detected DDIs during an interaction search. OncoRx is the first database of its kind which allows detection of ACD and chemotherapy regimen interactions with ADs. This tool will assist clinicians in improving clinical response and reducing adverse effects based on the therapeutic and toxicity profiles of the drugs.

A bibliometric analysis of the scientific literature on Internet, video games, and cell phone addiction.

2009-04-01

The aim of this study was to locate the scientific literature dealing with addiction to the Internet, video games, and cell phones and to characterize the pattern of publications in these areas. One hundred seventy-nine valid articles were retrieved from PubMed and PsycINFO between 1996 and 2005 related to pathological Internet, cell phone, or video game use. The years with the highest numbers of articles published were 2004 (n = 42) and 2005 (n = 40). The most productive countries, in terms of number of articles published, were the United States (n = 52), China (n = 23), the United Kingdom (n = 17), Taiwan (n = 13), and South Korea (n = 9). The most commonly used language was English (65.4%), followed by Chinese (12.8%) and Spanish (4.5%). Articles were published in 96 different journals, of which 22 published 2 or more articles. The journal that published the most articles was Cyberpsychology & Behavior (n = 41). Addiction to the Internet was the most intensely studied (85.3%), followed by addiction to video games (13.6%) and cell phones (2.1%). The number of publications in this area is growing, but it is difficult to conduct precise searches due to a lack of clear terminology. To facilitate retrieval, bibliographic databases should include descriptor terms referring specifically to Internet, video games, and cell phone addiction as well as to more general addictions involving communications and information technologies and other behavioral addictions.

Novel citation-based search method for scientific literature: application to meta-analyses.

PubMed

Janssens, A Cecile J W; Gwinn, M

2015-10-13

Finding eligible studies for meta-analysis and systematic reviews relies on keyword-based searching as the gold standard, despite its inefficiency. Searching based on direct citations is not sufficiently comprehensive. We propose a novel strategy that ranks articles on their degree of co-citation with one or more "known" articles before reviewing their eligibility. In two independent studies, we aimed to reproduce the results of literature searches for sets of published meta-analyses (n = 10 and n = 42). For each meta-analysis, we extracted co-citations for the randomly selected 'known' articles from the Web of Science database, counted their frequencies and screened all articles with a score above a selection threshold. In the second study, we extended the method by retrieving direct citations for all selected articles. In the first study, we retrieved 82% of the studies included in the meta-analyses while screening only 11% as many articles as were screened for the original publications. Articles that we missed were published in non-English languages, published before 1975, published very recently, or available only as conference abstracts. In the second study, we retrieved 79% of included studies while screening half the original number of articles. Citation searching appears to be an efficient and reasonably accurate method for finding articles similar to one or more articles of interest for meta-analysis and reviews.

Health-related quality of life assessment among patients with inflammatory bowel diseases after surgery – review

Formanowicz, Dorota; Gmerek, Łukasz; Krokowicz, Piotr

2016-01-01

Aim of the work was to review systematically the published literature addressing whether quality of life (QoL) and health-related QoL (HRQoL) are influenced by surgery among patients with inflammatory bowel disease (IBD). Electronic databases and published articles were searched to identify relevant studies published in the years 1990–2015. Then, a multistep selection was undertaken to identify articles that met specific selection criteria, such us specific key-words (IBD, HRQoL, ulcerative colitis (UC), Crohn’s disease (CD), and surgery), and the population was assessed (studies concerning patients < 18 years old were excluded). The review included 27 studies that were evaluated in the context of the influence of surgery on QoL and HRQoL. Concluding, with the increase in the incidence of IBD, monitoring of QoL is an important indicator of the health effects at each stage of the surgical treatment. PMID:28337230

Systematic literature search is a fundamental in evidence-based medicine. But systematic literature search is not yet a very well used way of retrieving evidence-based information. This article profiles a systematic literature search for evidence-based literature. It goes through the most central databases and gives an example of how to document the literature search. The article also sums up the literature search in all reviews in Ugeskrift for Laeger in the year 2004.

A quantitative literature-curated gold standard for kinase-substrate pairs

PubMed Central

2011-01-01

We describe the Yeast Kinase Interaction Database (KID, http://www.moseslab.csb.utoronto.ca/KID/), which contains high- and low-throughput data relevant to phosphorylation events. KID includes 6,225 low-throughput and 21,990 high-throughput interactions, from greater than 35,000 experiments. By quantitatively integrating these data, we identified 517 high-confidence kinase-substrate pairs that we consider a gold standard. We show that this gold standard can be used to assess published high-throughput datasets, suggesting that it will enable similar rigorous assessments in the future. PMID:21492431

To review possible associations reported between genetic variants and the risk, therapeutic response and prognosis of heart failure. Electronic databases (PubMed, Web of Science and CNKI) were systematically searched for relevant papers, published between January 1995 and February 2015. Eighty-two articles covering 29 genes and 39 polymorphisms were identified. Genetic association studies of heart failure have been highly controversial. There may be interaction or synergism of several genetic variants that together result in the ultimate pathological phenotype for heart failure. © The Author(s) 2016.

The cumulative index to Nursing and Allied Health Literature (CINAHL) is a useful research tool for accessing articles of interest to nurses and health care professionals. More than 2,800 journals are indexed by CINAHL and can be searched easily using assigned subject headings. Detailed instructions about conducting, combining, and saving searches in CINAHL are provided in this article. Establishing an account at EBSCO further allows a nurse to save references and searches and to receive e-mail alerts when new articles on a topic of interest are published.

Orbital decompression is the indicated procedure for addressing exophthalmos and compressive optic neuropathy in thyroid eye disease. There are an abundance of techniques for removal of orbital bone, fat, or a combination published in the scientific literature. The relative efficacy and complications of these interventions in relation to the specific indications remain as yet undocumented. We performed a systematic review of the current published evidence for the effectiveness of orbital decompression, possible complications, and impact on quality of life. We searched the current databases for medical literature and controlled trials, oculoplastic textbooks, and conference proceedings to identify relevant data up to February 2015. We included randomized controlled trials (RCTs) comparing two or more interventions for orbital decompression. We identified only two eligible RCTs for inclusion in the review. As a result of the significant variability between studies on decompression, i.e., methodology and outcome measures, we did not perform a meta-analysis. One study suggests that the transantral approach and endonasal technique had similar effects in reducing exophthalmos but the latter is safer. The second study provides evidence that intravenous steroids may be superior to primary surgical decompression in the management of compressive optic neuropathy requiring less secondary surgical procedures. Most of the published literature on orbital decompression consists of retrospective, uncontrolled trials. There is evidence from those studies that removal of the medial and lateral wall (balanced) and the deep lateral wall decompression, with or without fat removal, may be the most effective surgical methods with only few complications. There is a clear unmet need for controlled trials evaluating the different techniques for orbital decompression. Ideally, future studies should address the effectiveness, possible complications, quality of life, and cost of each intervention.

Significant growth has been seen in the field of anaesthesiology in recent decades. The current geographic distribution of the publications on anaesthesia research may be different from ten years ago. We performed this literature survey to examine the national origin of articles published in international anaesthesiology journals and to evaluate their contribution to anaesthesia research. Articles published in 18 major anaesthesiology journals from 2000 to 2009 were identified from the PubMed database and the Science Citation Index. A total of 30,191 articles were published in the selected 18 journals from 2000 to 2009. The country responsible for the largest number of articles was the United States of America (29.4%), followed by the United Kingdom, Germany, Japan, Canada, Australia and France. Denmark, Switzerland and Finland had the largest number of articles per capita. Anesthesia & Analgesia published the most number of articles from 2000 to 2009, followed by Anesthesiology, Pain and the British Journal of Anaesthesia. The numbers of clinical studies and randomised controlled trials decreased markedly from 2000 to 2009.

Multi-criteria decision analysis (MCDA) could potentially solve current methodological difficulties in the appraisal of orphan drugs. Areas covered: We provide an overview of the existing evidence regarding the use of MCDA in the appraisal of orphan drugs worldwide. Three databases (Pubmed, Embase, Web of Science) were searched for English, French and German literature published between January 2000 and April 2017. Full-text articles were supplemented with conference abstracts. A total of seven articles and six abstracts were identified. Expert commentary: The literature suggests that MCDA is increasingly being used in the context of appraising orphan drugs. It has shown itself to be a flexible approach with the potential to assist in decision-making regarding reimbursement for orphan drugs. However, further research regarding its application must be conducted.

2018-05-01

Anatomical variations or anomalies of the pancreatic ducts are important in the planning and performance of endoscopic retrograde cholangiopancreatography (ERCP) and surgical procedures of the pancreas. Normal pancreatic duct anatomy occurs in approximately 94.3% of cases, and multiple variations have been described for the remaining 5.7%. The purpose of this study was to review the literature on the pancreatic duct anatomy and to underline its importance in daily invasive endoscopic and surgical practice. Two main databases were searched for suitable articles published from 2000 to 2017, and results concerning more than 8,200 patients were included in the review. The most common anatomical variation was that of pancreas divisum, which appeared in approximately 4.5% of cases.

The purpose of this paper was to systematically review and synthesize the empirical literature on the effects of evidence-based therapy relationship (EBR) variables in the psychological treatment for adults who experienced trauma-related distress. Studies were identified using comprehensive searches of PsycINFO, Medline, Published International Literature on Traumatic Stress, and Cumulative Index to Nursing and Allied Health Literature databases. Included in the review were articles published between 1980 and 2015, in English that reported on the impact of EBRs on treatment outcome in clinical samples of adult trauma survivors. Nineteen unique studies met inclusion criteria. The bulk of the studies were on therapeutic alliance and the vast majority found that alliance was predictive of or associated with a reduction in various symptomotology. Methodological concerns included the use of small sample sizes, little information on EBRs beyond alliance as well as variability in its measurement, and non-randomized assignment to treatment conditions or the lack of a comparison group. More research is needed on the roles of client feedback, managing countertransference, and other therapist characteristics on treatment outcome with trauma survivors. Understanding the role of EBRs in the treatment of trauma survivors may assist researchers, clinicians, and psychotherapy educators to improve therapist training as well as client engagement and retention in treatment.

This review identifies the prominent topics in the literature pertaining to the ethical, legal, and social issues (ELSI) raised by research investigating personalized genomic medicine (PGM). The abstracts of 953 articles extracted from scholarly databases and published during a 5-year period (2008-2012) were reviewed. A total of 299 articles met our research criteria and were organized thematically to assess the representation of ELSI issues for stakeholders, health specialties, journals, and empirical studies. ELSI analyses were published in both scientific and ethics journals. Investigational research comprised 45% of the literature reviewed (135 articles) and the remaining 55% (164 articles) comprised normative analyses. Traditional ELSI concerns dominated the discourse including discussions about disclosure of research results. In fact, there was a dramatic increase in the number of articles focused on the disclosure of research results and incidental findings to research participants. Few papers focused on particular disorders, the use of racial categories in research, international communities, or special populations (e.g., adolescents, elderly patients, or ethnic groups). Considering that strategies in personalized medicine increasingly target individuals' unique health conditions, environments, and ancestries, further analysis is needed on how ELSI scholarship can better serve the increasingly global, interdisciplinary, and diverse PGM research community. © 2016 John Wiley & Sons Ltd.

At times the clinicians are challenged with variations in morphology of root canal. This review article attempts to list out all the variations of permanent mandibular first molar published so for in the literature. Materials and Methods: An exhaustive search was undertaken using PUBMED database to identify published literature from 1900 to 2010 relating to the root canal morphology of permanent first molar by using key words. The selected artcles were obtained and reviewed. Results: Total ninty seven articles were selected out of which 50 were original article and forty seven were case reports. The incidence of third canal in mesial root was 0.95% to 15%. The incidence of three rooted mandibular first molar was 3% to 33%. Only ninety cases reported with c-shape canal configuration. Incidence of Taurodintism without congenital disorder was very rare. Conclusion: The root canal treatment requires proper knowlegde of variations in root canal morphology in order to recognise, disinfect and seal all portal of exit. This can be accomplished with proper diagnosis using newer modes, modification in access preparation, use of operating microscope, enhanced methods of disinfecting and sealing of all canals.

Cross-border reproductive care (CBRC) has attracted considerable attention in media and professional publications. The aim of this review is to present a critical narrative overview of the published evidence on CBRC. A systematic search of key academic databases was undertaken with no time restrictions set for publication. This was supplemented by additional searches of key websites, reference chaining and enquiries to people working in the field. A total of 54 items are included in the review, including both empirical research studies (18) and debate papers (36). The key themes discussed are: terminology and definitions; incidence; experiences; explanations; implications; and policy responses. Significant methodological limitations and gaps in the literature are identified. Evidence on incidence is scant, though it suggests that CBRC is increasing. The literature suggests legal, social and political drivers, which vary in importance geographically and between individuals. Limited findings on patient perceptions suggest a broadly positive patient experience. Suggested policy responses include prohibition, regulatory harmonization and harm minimization. There is a need for better international data collection tools and both quantitative and qualitative work which encompasses views of patients, donors, surrogates and professionals and which explores the implications for healthcare services in sending countries.

To review the literature on consumers' knowledge, attitudes and opinions of the use of generic medicines. A narrative review of studies conducted from 1970 to 2008 on consumers perceptions and views towards generic medicines was performed. An extensive literature search was undertaken using indexing services available at the authors' institution library. The following keywords were used for the search: brand, generic, multisource, medications, medicines, drugs, pharmaceuticals and consumers, customers, and patients. Electronic databases searched were Medline, Inside Web, ISI Web of Knowledge, Science Direct, Springer Link, JSTOR, Proquest, Ebsco Host and Google Scholar. These electronic databases were searched for full text papers published in English from 1970 to October 2008. Twenty studies were identified. Eleven were from the USA, four were from Europe, two were from Canada and one each was from Australia, Brazil and Malaysia. In general, consumers showed mixed reactions towards the use of generic medicines. This was evident from the divergence of views observed by country development level, consumers' socioeconomic characteristics, drug product characteristics, pharmaceutical reimbursement system, policy environment, contact with health care professionals, past experience with medications, and knowledge of the seriousness of a medical condition. Patient confidence and knowledge pertaining to generic medicines use have increased over the past four decades, especially in developed countries. Mass educational efforts, financial incentives, and greater communication among patients and health care professionals were seen as major drivers to the uptake of generic medicines among consumers.

Overviews of the current literature only provide summaries of existing relevant preventive strategies for dental erosion. To perform a systematic review according to the quantitative meta-analysis method of the scientific literature on prevention of dental erosion. The focused question will address primary prevention of dental erosion by calcium and fluoride. Randomized clinical trials (RCTs) regarding dental erosion prevention. The search included five databases: Embase, Cochrane database of systematic reviews, PubMed (MEDLINE), FDA publication and Berman medical library of the Hebrew University. The search included data in the English language, with effect on preventing dental erosion always presented as mean enamel loss and measured by profilometer. Statistical meta-analysis was performed by StatsDirect program and PEPI statistical software. Fixed- and random-effect models were used to analyse the data. Heterogeneity tests were employed to validate the fixed-effect model assumption. A total of 475 articles on dental erosion prevention were located. A four-stage selection process was employed, and 10 RCT articles were found to be suitable for meta-analysis. The number of studies on prevention of dental erosion maintaining standards of evidence-based dentistry remains insufficient to reach any definite conclusions. The focused questions of this review cannot be addressed according to the existing literature. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The objective of this study was to determine already reported cases of transmission/reception failure and interferences to evaluate the safety and security of the new mobile home telemedicine systems. The literature published in the last 10 years (1998-2009) has been reviewed, by searching in several databases. Searches on transmission effectiveness and electromagnetic compatibility were made manually through journals, conference proceedings, and also the healthcare technology assessment agencies' Web pages. Search strategies developed through electronic databases and manual search identified a total of 886 references, with 44 finally being included in the results. They have been divided by technology in the transmission/reception effectiveness studies, and according to the type of medical device in the case of electromagnetic interferences studies. The study reveals that there are numerous publications on telemedicine and home-monitoring systems using wireless networks. However, literature on effectiveness in terms of connectivity and transmission problems and electromagnetic interferences is limited. From the collected studies, it can be concluded that there are transmission failures, low-coverage areas, errors in the transmission of packets, and so on. Moreover, cases of serious interferences in medical instruments have also been reported. These facts highlight the lack of studies and specific recommendations to be followed in the implementation of biomonitoring systems in domestic environments using wireless networks.

Background: Titanium has been the most popular material of choice for dental implantology over the past few decades. Its properties have been found to be most suitable for the success of implant treatment. But recently, zirconia is slowly emerging as one of the materials which might replace the gold standard of dental implant, i.e., titanium. Materials and Methods: Literature was searched to retrieve information about zirconia dental implant and studies were critically analyzed. PubMed database was searched for information about zirconia dental implant regarding mechanical properties, osseointegration, surface roughness, biocompatibility, and soft tissue health around it. The literature search was limited to English language articles published from 1975 to 2015. Results: A total of 45 papers met the inclusion criteria for this review, among the relevant search in the database. Conclusion: Literature search showed that some of the properties of zirconia seem to be suitable for making it an ideal dental implant, such as biocompatibility, osseointegration, favourable soft tissue response and aesthetics due to light transmission and its color. At the same time, some studies also point out its drawbacks. It was also found that most of the studies on zirconia dental implants are short-term studies and there is a need for more long-term clinical trials to prove that zirconia is worth enough to replace titanium as a biomaterial in dental implantology.

OBJECTIVE Markov modeling is a clinical research technique that allows competing medical strategies to be mathematically assessed in order to identify the optimal allocation of health care resources. The authors present a review of the recently published neurosurgical literature that employs Markov modeling and provide a conceptual framework with which to evaluate, critique, and apply the findings generated from health economics research. METHODS The PubMed online database was searched to identify neurosurgical literature published from January 2010 to December 2017 that had utilized Markov modeling for neurosurgical cost-effectiveness studies. Included articles were then assessed with regard to year of publication, subspecialty of neurosurgery, decision analytical techniques utilized, and source information for model inputs. RESULTS A total of 55 articles utilizing Markov models were identified across a broad range of neurosurgical subspecialties. Sixty-five percent of the papers were published within the past 3 years alone. The majority of models derived health transition probabilities, health utilities, and cost information from previously published studies or publicly available information. Only 62% of the studies incorporated indirect costs. Ninety-three percent of the studies performed a 1-way or 2-way sensitivity analysis, and 67% performed a probabilistic sensitivity analysis. A review of the conceptual framework of Markov modeling and an explanation of the different terminology and methodology are provided. CONCLUSIONS As neurosurgeons continue to innovate and identify novel treatment strategies for patients, Markov modeling will allow for better characterization of the impact of these interventions on a patient and societal level. The aim of this work is to equip the neurosurgical readership with the tools to better understand, critique, and apply findings produced from cost-effectiveness research.

Systematic analysis of integral aspects within sport enables improvement in performance. One key aspect is the management and prevention of injuries. Bibliometrics is a systematic method for evaluating research output. It may be expected that the quantity and quality of sports injury research over time may strongly correlate with the timing of the Olympic games. This study was conducted to determine the effect of the Olympic legacy on academic sports medicine and evidence to prevent injuries of the face and teeth. A literature search within the PubMed database was undertaken to identify the quantity of literature published annually between 1996 and 2015 in the fields of sports injuries and injury prevention. The top 5 journals publishing in each field were then identified and the change in their impact factor (IF) was investigated. It was seen that, since 1996, there has been an overall increase in the quantity of literature published regarding sports injuries and prevention of sports injuries of 209% and 217%, respectively. Publications regarding facial injuries and dental injuries within sport show an increase of 114% and 71%, respectively. There was an increase in IF since 2000 in almost every journal investigated. A strong, positive correlation is seen among journals publishing on the prevention of sports injuries, showing a median IF increase of 2.8198. No statistical significance was found between Olympic years and the number of publications. Hence, there has been a gradual increase in both the quality and quantity of publications regarding sports injuries since 1996. However, there appears to be no immediate added effect of the “Olympic legacy” following each Olympic games on the quantity or quality of publications in these fields. PMID:28032040

A new programme of systematic reviews of randomised controlled trials (RCTs) in homeopathy will distinguish important attributes of RCT records, including: placebo controlled versus other-than-placebo (OTP) controlled; individualised versus non-individualised homeopathy; peer-reviewed (PR) versus non peer-reviewed (NPR) sources. (a) To outline the methods used to search and categorise the RCT literature; (b) to report details of the records retrieved; (c) to compare our retrieved records with those reported in two previous systematic reviews (Linde et al., 1997; Shang et al., 2005). Ten major electronic databases were searched for records published up to the end of 2011. A record was accepted for subsequent systematic review if it was a substantive report of a clinical trial of homeopathic treatment or prophylaxis in humans, randomised and controlled, and published in a PR or NPR journal. 489 records were potentially eligible: 226 were rejected as non-journal, minor or repeat publications, or lacking randomisation and/or controls and/or a 'homeopathic' intervention; 263 (164 PR, 99 NPR) were acceptable for systematic review. The 263 accepted records comprised 217 (137 PR, 80 NPR) placebo-controlled RCTs, of which 121 were included by, 66 were published after, and 30 were potentially eligible for, but not listed by, Linde or Shang. The 137 PR records of placebo-controlled RCTs comprise 41 on individualised homeopathy and 96 on non-individualised homeopathy. Our findings clarify the RCT literature in homeopathy. The 263 accepted journal papers will be the basis for our forthcoming programme of systematic reviews. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd. All rights reserved.

To critically analyze the inclusion of individuals with special needs in regular education in Brazil, considering social and legal aspects, through literature review. The literature search was conducted in open access databases: LILACS, SciELO, Portal Cochrane and IUSDATA, the latter belonging to the Library of the Law School of the University of São Paulo, considering all articles published until December 2010. The search strategy used the following keywords: inclusive education; special education; inclusive proposal; individuals with special needs. In the search, only studies in which the summary or the body of the article were related to the purpose of the study were evaluated and selected. The potentially relevant articles for review were presented in a protocol form containing the eligibility criteria of the study, methods used, characteristics of the analyzed group or manuscripts, type of intervention used in the study, and results obtained. Articles classified as expert opinions, despite their low level of scientific evidence, were considered in this work, since they are often found in the literature on the issue. A total of 1,399 articles was found and 120 potentially relevant articles were selected after reading their abstracts. From these, 67 articles were cited in more than one database, which resulted in 53 articles to be fully read. Fifteen of these articles were excluded after reading because they did not meet the inclusion criteria. Thus, 38 studies were included and analyzed. Following a critical analysis of the literature in the field, it was concluded that, so far, in general, the school receives individuals with special needs; however, there is a long way to go to actually include these individuals, although Brazil has the scope of inclusion. Therefore, it is necessary to establish public policies and guidelines aimed at effective inclusion.

Multiple approaches exist, both in theory and in practice, to reduce young people's risk of violent victimization when they are in school. Among these approaches, a growing number of school districts are choosing to install metal detectors. We sought to review the literature available on the impacts of metal detectors on school violence and perceptions about school violence. We conducted an extensive literature search, including databases for the medical, public health, sociology, and political science literature. Of 128 papers that met our search criteria, 7 studies met inclusion criteria for the literature review. Each of the papers reviewed utilized data that originated from self-report surveys. Four of the studies consisted of secondary analyses of national databases, with the other 3 utilizing local surveys. The studies varied as to the outcome, ranging from student/staff perceptions of safety at school to student self-reports of weapon carrying and/or victimization, and showed mixed results. Several studies suggested potential detrimental effects of metal detectors on student perceptions of safety. One study showed a significant beneficial effect, linking metal detector use to a decrease in the likelihood that students reported carrying a weapon while in school (7.8% vs 13.8%), without a change in weapon carrying in other settings or a decline in participation in physical fights. There is insufficient data in the literature to determine whether the presence of metal detectors in schools reduces the risk of violent behavior among students, and some research suggests that the presence of metal detectors may detrimentally impact student perceptions of safety. © Published 2011.

This article reports on five separate studies designed for the National Library of Medicine (NLM) to develop and test methodologies for evaluating the products of large databases. The methodologies were tested on literatures of the medical behavioral sciences (MBS). One of these studies examined how well NLM covered MBS monographic literature using CATLINE and OCLC. Another examined MBS journal and serial literature coverage in MEDLINE and other MBS-related databases available through DIALOG. These two studies used 1010 items derived from the reference lists of sixty-one journals, and tested for gaps and overlaps in coverage in the various databases. A third study examined the quality of the indexing NLM provides to MBS literatures and developed a measure of indexing as a system component. The final two studies explored how well MEDLINE retrieved documents on topics submitted by MBS professionals and how online searchers viewed MEDLINE (and other systems and databases) in handling MBS topics. The five studies yielded both broad research outcomes and specific recommendations to NLM.

The website Sci-Hub enables users to download PDF versions of scholarly articles, including many articles that are paywalled at their journal’s site. Sci-Hub has grown rapidly since its creation in 2011, but the extent of its coverage has been unclear. Here we report that, as of March 2017, Sci-Hub’s database contains 68.9% of the 81.6 million scholarly articles registered with Crossref and 85.1% of articles published in toll access journals. We find that coverage varies by discipline and publisher, and that Sci-Hub preferentially covers popular, paywalled content. For toll access articles, we find that Sci-Hub provides greater coverage than the University of Pennsylvania, a major research university in the United States. Green open access to toll access articles via licit services, on the other hand, remains quite limited. Our interactive browser at https://greenelab.github.io/scihub allows users to explore these findings in more detail. For the first time, nearly all scholarly literature is available gratis to anyone with an Internet connection, suggesting the toll access business model may become unsustainable. PMID:29424689

Clinicians are challenged to identify new practice-changing articles in the medical literature. To identify the practice-changing articles published in 2017 most relevant to outpatient general internal medicine, 5 internists reviewed the following sources: 1) titles and abstracts from internal medicine journals with the 7 highest impact factors, including New England Journal of Medicine, Lancet, Journal of the American Medical Association, British Medical Journal, Public Library of Science Medicine, Annals of Internal Medicine, and JAMA Internal Medicine; 2) synopses and syntheses of individual studies, including collections in the American College of Physicians Journal Club, Journal Watch, and Evidence-Based Medicine; 3) databases of synthesis, including Evidence Updates and the Cochrane Library. Inclusion criteria were perceived clinical relevance to outpatient general medicine, potential for practice change, and strength of evidence. This process yielded 140 articles. Clusters of important articles around one topic were considered as a single-candidate series. A modified Delphi method was utilized by the 5 authors to reach consensus on 7 topics to highlight and appraise from the 2017 literature. Copyright © 2018 Elsevier Inc. All rights reserved.

Febuxostat for the treatment of gout.

PubMed

Bridgeman, Mary Barna; Chavez, Benjamin

2015-02-01

Gout is a rheumatologic condition associated with elevated serum uric acid levels and deposition of monosodium urate crystals in joints and soft tissues. The xanthine oxidase inhibitor, allopurinol, has historically been the principle agent utilized for reducing elevated uric acid levels and treating underlying cause of gout symptoms; the availability of febuxostat, a newer non-purine selective xanthine oxidase inhibitor, represents an alternative therapy for those patients with contraindications or intolerance to allopurinol. This article reviews the published literature on the pharmacologic characteristics and clinical safety and efficacy data on the use of febuxostat in the treatment of gout. A literature search of MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations Databases (1996-November 2014) was conducted utilizing the key words 'febuxostat', 'allopurinol', and 'gout'. All published articles regarding febuxostat were evaluated. References of selected articles, data from poster presentations, and abstract publications were additionally reviewed. Febuxostat has shown benefit with respect to symptomatic relief and uric acid level reduction. The safety profile of this agent makes it an ideal alternative in those patients with contraindications to or who are intolerant of allopurinol.

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.

A systematic review of microfinance and women's health literature: Directions for future research.

PubMed

O'Malley, T L; Burke, J G

2017-11-01

While growing evidence suggests that microfinance is an effective approach for improved women's health, a significant gap remains in our understanding. The objective of this review is to synthesise the findings from published literature focused on microfinance and health issues particularly affecting women, including HIV/AIDS, reproductive health, mental health, and violence. Forty-one articles that examine the impact of microfinance participation on women's health were identified through a systematic search of electronic databases, coded using a structured abstraction form, and synthesised. Review results indicate that the impact of microfinance on women's health is an area in great need of research and publication attention. Varied quality and reporting in the identified articles restricted the ability to draw concrete conclusions regarding the relationship between microfinance participation and women's health, but led to the identification of current gaps in existing published research. Future research should work to address the recommendations provided in order to offer additional evidence to better understand the use of microfinance programming as a structural intervention to improve women's health.

Background Synthesis of data from published human genetic association studies is a critical step in the translation of human genome discoveries into health applications. Although genetic association studies account for a substantial proportion of the abstracts in PubMed, identifying them with standard queries is not always accurate or efficient. Further automating the literature-screening process can reduce the burden of a labor-intensive and time-consuming traditional literature search. The Support Vector Machine (SVM), a well-established machine learning technique, has been successful in classifying text, including biomedical literature. The GAPscreener, a free SVM-based software tool, can be used to assist in screening PubMed abstracts for human genetic association studies. Results The data source for this research was the HuGE Navigator, formerly known as the HuGE Pub Lit database. Weighted SVM feature selection based on a keyword list obtained by the two-way z score method demonstrated the best screening performance, achieving 97.5% recall, 98.3% specificity and 31.9% precision in performance testing. Compared with the traditional screening process based on a complex PubMed query, the SVM tool reduced by about 90% the number of abstracts requiring individual review by the database curator. The tool also ascertained 47 articles that were missed by the traditional literature screening process during the 4-week test period. We examined the literature on genetic associations with preterm birth as an example. Compared with the traditional, manual process, the GAPscreener both reduced effort and improved accuracy. Conclusion GAPscreener is the first free SVM-based application available for screening the human genetic association literature in PubMed with high recall and specificity. The user-friendly graphical user interface makes this a practical, stand-alone application. The software can be downloaded at no charge. PMID:18430222

Yellow fever vaccine-associated viscerotropic disease: current perspectives.

PubMed

Thomas, Roger E

2016-01-01

To assess those published cases of yellow fever (YF) vaccine-associated viscerotropic disease that meet the Brighton Collaboration criteria and to assess the safety of YF vaccine with respect to viscerotropic disease. Ten electronic databases were searched with no restriction of date or language and reference lists of retrieved articles. All abstracts and titles were independently read by two reviewers and data independently entered by two reviewers. All serious adverse events that met the Brighton Classification criteria were associated with first YF vaccinations. Sixty-two published cases (35 died) met the Brighton Collaboration viscerotropic criteria, with 32 from the US, six from Brazil, five from Peru, three from Spain, two from the People's Republic of China, one each from Argentina, Australia, Belgium, Ecuador, France, Germany, Ireland, New Zealand, Portugal, and the UK, and four with no country stated. Two cases met both the viscerotropic and YF vaccine-associated neurologic disease criteria. Seventy cases proposed by authors as viscerotropic disease did not meet any Brighton Collaboration viscerotropic level of diagnostic certainty or any YF vaccine-associated viscerotropic disease causality criteria (37 died). Viscerotropic disease is rare in the published literature and in pharmacovigilance databases. All published cases were from developing countries. Because the symptoms are usually very severe and life threatening, it is unlikely that cases would not come to medical attention (but might not be published). Because viscerotropic disease has a highly predictable pathologic course, it is likely that viscerotropic disease post-YF vaccine occurs in low-income countries with the same incidence as in developing countries. YF vaccine is a very safe vaccine that likely confers lifelong immunity.

Effective components of exercise and physical activity-related behaviour-change interventions for chronic non-communicable diseases in Africa: protocol for a systematic mixed studies review with meta-analysis

Introduction Chronic non-communicable diseases (NCDs) account for a high burden of mortality and morbidity in Africa. Evidence-based clinical guidelines recommend exercise training and promotion of physical activity behaviour changes to control NCDs. Developing such interventions in Africa requires an understanding of the essential components that make them effective in this context. This is a protocol for a systematic mixed studies review that aims to determine the effective components of exercise and physical activity-related behaviour-change interventions for chronic diseases in Africa, by combining quantitative and qualitative research evidence from studies published until July 2015. Methods and analysis We will conduct a detailed search to identify all published and unpublished studies that assessed the effects of exercise and physical activity-related interventions or the experiences/perspectives of patients to these interventions for NCDs from bibliographic databases and the grey literature. Bibliographic databases include MEDLINE, EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), PsycINFO, CINAHL and Web of Science. We will include the following African regional databases: African Index Medicus (AIM) and AFROLIB, which is the WHO's regional office database for Africa. The databases will be searched from inception until 18 July 2015. Appraisal of study quality will be performed after results synthesis. Data synthesis will be performed independently for quantitative and qualitative data using a mixed methods sequential explanatory synthesis for systematic mixed studies reviews. Meta-analysis will be conducted for the quantitative studies, and thematic synthesis for qualitative studies and qualitative results from the non-controlled observational studies. The primary outcome will include exercise adherence and physical activity behaviour changes. This review protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. Ethics and dissemination There is no ethical requirement for this study, as it utilises published data. This review is expected to inform the development of exercise and physical activity-related behaviour-change interventions in Africa, and will be presented at conferences, and published in peer reviewed journals and a PhD thesis at King's College London. Protocol registration number This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 22 January 2015 (registration number: PROSPERO 2015: CRD42015016084).

Background The scoping review has become an increasingly popular approach for synthesizing research evidence. It is a relatively new approach for which a universal study definition or definitive procedure has not been established. The purpose of this scoping review was to provide an overview of scoping reviews in the literature. Methods A scoping review was conducted using the Arksey and O'Malley framework. A search was conducted in four bibliographic databases and the gray literature to identify scoping review studies. Review selection and characterization were performed by two independent reviewers using pretested forms. Results The search identified 344 scoping reviews published from 1999 to October 2012. The reviews varied in terms of purpose, methodology, and detail of reporting. Nearly three-quarter of reviews (74.1%) addressed a health topic. Study completion times varied from 2 weeks to 20 months, and 51% utilized a published methodological framework. Quality assessment of included studies was infrequently performed (22.38%). Conclusions Scoping reviews are a relatively new but increasingly common approach for mapping broad topics. Because of variability in their conduct, there is a need for their methodological standardization to ensure the utility and strength of evidence. © 2014 The Authors.

This study aims to conduct a literature review to evaluate the effectiveness of intervention programs in the prevention and control of obesity in children and to map the locations where the studies were carried out. A systematic review using the PubMed / MEDLINE and LILACS databases to trace the published literature on intervention programs for prevention and control of obesity in the period of January 2004 to October 2013. The initial search was conducted using the terms "body mass index", " Intervention" and "children" or "adolescent" and only articles published in English, Spanish or Portuguese were selected. We found that interventions based only on advice had modest results in identifying changes in the anthropometric indicators of children and adolescents over time, although they appear to be effective in promoting positive changes in the eating habits of this population. Among the studies identified, 77.8 % were conducted in high-income countries, 22.2 % in middle to high income countries and no intervention studies were found in middle to low income countries. Intervention programs based only on counseling are effective in promoting changes in dietary patterns, but show poor results in the changes of anthropometric parameters of children and adolescents.

Borg, Johan; Lindström, Anna; Larsson, Stig

2011-03-01

The 'Convention on the Rights of Persons with Disabilities' (CRPD) requires governments to meet the assistive technology needs of citizens. However, the access to assistive technology in developing countries is severely limited, which is aggravated by a lack of related services. To summarize current knowledge on assistive technology for low- and lower-middle-income countries published in 1995 or later, and to provide recommendations that facilitate implementation of the CRPD. Literature review. Literature was searched in web-based databases and reference lists. Studies carried out in low- and lower-middle-income countries, or addressing assistive technology for such countries, were included. The 52 included articles are dominated by product oriented research on leg prostheses and manual wheelchairs. Less has been published on hearing aids and virtually nothing on the broad range of other types of assistive technology. To support effective implementation of the CRPD in these countries, there is a need for actions and research related particularly to policies, service delivery, outcomes and international cooperation, but also to product development and production. The article has a potential to contribute to CRPD compliant developments in the provision of assistive technology in developing countries by providing practitioners with an overview of published knowledge and researchers with identified research needs.

A literature review of disaster nursing competencies in Japanese nursing journals.

Kako, Mayumi; Mitani, Satoko

2010-01-01

Competencies is an important concept used for assessing health professionals' capability to perform their role. By means of a literature review of Japanese professional journals this paper will investigate the competencies concept, particularly with relation to disaster nursing. The literature research was conducted using the database ichu-shi (ver. 4). All literature is written and published in Japanese and was published between 2001 and 2008. Due to an unfamiliarity of the term 'competencies' in Japanese, the key words were sought while deconstructing the meaning and concepts of 'competencies' into terms more recognisable in the Japanese context. Twelve key words: disaster, capability, education, practice, licensure, ability, function, prevention, response, planning, emergency, and disaster nursing were chosen as being most likely to find literature relevant to the English Language concept of competencies. The searched articles were then written into the disaster nursing competencies review worksheet for analysis. One hundred and twenty articles were found by searching a combination of these key words. Of these articles, those that were not in the context of disaster nursing were eliminated. As a result, 43 articles were chosen as being suitable for analysis of the context. These articles are classified into four themes. These theme groups indicated a foundation for competencies in disaster nursing. The definition of competencies in Japanese nursing journals was quite varied and cannot be easily defined as common disaster nursing competencies. Given the variety of areas and the distinct phases in disaster nursing, as well as the 'what for' and 'who governs', disaster nursing competencies will need its own discussion in order to establish the common competencies internationally.

Different structures and coding schemes may limit rapid evaluation of a large pool of potential drug safety signals using multiple longitudinal healthcare databases. To overcome this restriction, a semi-automated approach utilising common data model (CDM) and robust pharmacoepidemiologic methods was developed; however, its performance needed to be evaluated. Twenty-three established drug-safety associations from publications were reproduced in a healthcare claims database and four of these were also repeated in electronic health records. Concordance and discrepancy of pairwise estimates were assessed between the results derived from the publication and results from this approach. For all 27 pairs, an observed agreement between the published results and the results from the semi-automated approach was greater than 85% and Kappa coefficient was 0.61, 95% CI: 0.19-1.00. Ln(IRR) differed by less than 50% for 13/27 pairs, and the IRR varied less than 2-fold for 19/27 pairs. Reproducibility based on the intra-class correlation coefficient was 0.54. Most covariates (>90%) in the publications were available for inclusion in the models. Once the study populations and inclusion/exclusion criteria were obtained from the literature, the analysis was able to be completed in 2-8 h. The semi-automated methodology using a CDM produced consistent risk estimates compared to the published findings for most selected drug-outcome associations, regardless of original study designs, databases, medications and outcomes. Further assessment of this approach is useful to understand its roles, strengths and limitations in rapidly evaluating safety signals.

Kyphosis and review of the literature.

PubMed

Yaman, Onur; Dalbayrak, Sedat

2014-01-01

The term kyphosis is used to describe the spinal curve that results in an abnormally rounded back. Kyphosis may develop due to trauma, developmental anomalies, degenerative disc disease, inflammatory diseases, and infectious diseases and also iatrogenic. The aim of this paper is to review the etiopathognesis and the treatment management of kyphosis. A search in the National Library of Medicine (Pubmed) database using key word 'kyphosis' and was made. For the literature review, papers concerning etiopathogenesis, classification and treatment were selected among these papers. A search in the National Library of Medicine (Pubmed) database using key word 'kyphosis' yielded 7506 papers published between 1916 and 2013. The main papers about kyphosis were congenital, Scheuermann, tumour related, neuromuscular, posttraumatic, infectionrelated, iatrogenic kyphosis. Every patient with kyphosis should be treated based on her/his current state and needs. It should always be remembered that the patients with negative sagittal balance can compensate it with the hip flexion but it is far more difficult to compensate the positive sagittal balance. The main goal of surgery to treat the kyphotic patients is to correct the sagittal curve and also restore a spinal balance within an acceptable range above the hips and knees.

The Efficacy of Equine-Assisted Activities and Therapies on Improving Physical Function.

To summarize the physical benefits of therapeutic horseback riding and hippotherapy and suggest directions for future research. Review of databases for peer-reviewed articles related to equine-assisted activities and therapies. Databases included MEDLINE via EBSCO, Web of Science, PubMed, Google Scholar, and Academic Search Complete. Articles were limited to those with full-text access published in English since 1987. Acute and residual improvements in physical benefits, such as gross motor function (e.g., walking, running, jumping), spasticity, muscle symmetry, posture, balance, and gait occur in adults and children with varying disabilities. The benefits appear to be greatest following multiweek interventions with one or more sessions per week. Modest acute cardiovascular responses are observed during equine-assisted activities and therapies with little or no evidence for training improvements in heart rate or blood pressure at rest or during riding. The present body of literature provides evidence that equine-assisted activities and therapies are an effective means of improving many measures of physical health. However, more controlled trials are urgently needed to strengthen the current knowledge base, establish dose-response characteristics of equine-assisted activities and therapies, and explore the physiologic basis for the promising results suggested from the literature.

Sensory overload: A concept analysis.

2017-04-01

In the context of mental disorders sensory overload is a widely described phenomenon used in conjunction with psychiatric interventions such as removal from stimuli. However, the theoretical foundation of sensory overload as addressed in the literature can be described as insufficient and fragmentary. To date, the concept of sensory overload has not yet been sufficiently specified or analyzed. The aim of the study was to analyze the concept of sensory overload in mental health care. A literature search was undertaken using specific electronic databases, specific journals and websites, hand searches, specific library catalogues, and electronic publishing databases. Walker and Avant's method of concept analysis was used to analyze the sources included in the analysis. All aspects of the method of Walker and Avant were covered in this concept analysis. The conceptual understanding has become more focused, the defining attributes, influencing factors and consequences are described and empirical referents identified. The concept analysis is a first step in the development of a middle-range descriptive theory of sensory overload based on social scientific and stress-theoretical approaches. This specification may serve as a fundament for further research, for the development of a nursing diagnosis or for guidelines. © 2017 Australian College of Mental Health Nurses Inc.

Learning concepts of cinenurducation: an integrative review.

PubMed

Oh, Jina; Kang, Jeongae; De Gagne, Jennie C

2012-11-01

Cinenurducation is the use of films in both didactic and clinical nursing education. Although films are already used as instructional aids in nursing education, few studies have been made that demonstrate the learning concepts that can be attributed to this particular teaching strategy. The purpose of this paper is to describe the learning concepts of cinenurducation and its conceptual metaphor based on a review of literature. The databases CINAHL, MEDLINE, PsychINFO, ERIC, EBSCO, ProQuest Library Journal, and Scopus databases were searched for articles. Fifteen peer-reviewed articles were selected through title and abstract screening from "films in nursing" related articles found in internationally published articles in English from the past 20 years. Four common concepts emerged that relate to cinenurducation: (a) student-centered, (b) experiential, (c) reflective, and (d) problem-solving learning. Current literature corroborates cinenurducation as an effective teaching strategy with its learning activities in nursing education. Future studies may include instructional guides of sample films that could be practically used in various domains to teach nursing competencies, as well as in the development of evaluation criteria and standards to assess students' learning outcomes.

Reasons to temper enthusiasm about open access nursing journals.

PubMed

de Jong, Gideon

2017-04-01

Open access is a relatively new phenomenon within nursing science. Several papers from various nursing journals have been published recently on the disadvantages of the traditional model of purchasing proprietary fee-based databases to access scholarly information. Just few nursing scholars are less optimistic about the possible benefits of open access nursing journals. A critical reflection on the merits and pitfalls of open access journals along insights from the literature and personal opinion. Two arguments are discussed, providing justification for tempering enthusiasm about open access journals. First, only research groups with sufficient financial resources can publish in open access journals. Second, open access has conflicting incentives, where the aim is to expand production at the expense of publishing quality articles; a business model that fits well into a neoliberal discourse. There are valid reasons to criticise the traditional publishers for the excessive costs of a single article, therefore preventing the dissemination of scholarly nursing information. On the contrary, the business model of open access publishers is no less imbued with the neoliberal tendency of lining the pockets.

Development of the ECODAB into a relational database for Escherichia coli O-antigens and other bacterial polysaccharides.

Escherichia coli O-antigen database (ECODAB) is a web-based application to support the collection of E. coli O-antigen structures, polymerase and flippase amino acid sequences, NMR chemical shift data of O-antigens as well as information on glycosyltransferases (GTs) involved in the assembly of O-antigen polysaccharides. The database content has been compiled from scientific literature. Furthermore, the system has evolved from being a repository to one that can be used for generating novel data on its own. GT specificity is suggested through sequence comparison with GTs whose function is known. The migration of ECODAB to a relational database has allowed the automation of all processes to update, retrieve and present information, thereby, endowing the system with greater flexibility and improved overall performance. ECODAB is freely available at http://www.casper.organ.su.se/ECODAB/. Currently, data on 169 E. coli unique O-antigen entries and 338 GTs is covered. Moreover, the scope of the database has been extended so that polysaccharide structure and related information from other bacteria subsequently can be added, for example, from Streptococcus pneumoniae. © The Author 2014.

A bibliography of literature pertaining to plague (Yersinia pestis)

USGS Publications Warehouse

Ellison, Laura E.; Frank, Megan K. Eberhardt

2011-01-01

Plague is an acute and often fatal zoonotic disease caused by the bacterium Yersinia pestis. Y. pestis mainly cycles between small mammals and their fleas; however, it has the potential to infect humans and frequently causes fatalities if left untreated. It is often considered a disease of the past; however, since the late 1800s, plagueis geographic range has expanded greatly, posing new threats in previously unaffected regions of the world, including the Western United States. A literature search was conducted using Internet resources and databases. The keywords chosen for the searches included plague, Yersinia pestis, management, control, wildlife, prairie dogs, fleas, North America, and mammals. Keywords were used alone or in combination with the other terms. Although this search pertains mostly to North America, citations were included from the international research community, as well. Databases and search engines used included Google (http://www.google.com), Google Scholar (http://scholar.google.com), SciVerse Scopus (http://www.scopus.com), ISI Web of Knowledge (http://apps.isiknowledge.com), and the USGS Library's Digital Desktop (http://library.usgs.gov). The literature-cited sections of manuscripts obtained from keyword searches were cross-referenced to identify additional citations or gray literature that was missed by the Internet search engines. This Open-File Report, published as an Internet-accessible bibliography, is intended to be periodically updated with new citations or older references that may have been missed during this compilation. Hence, the authors would be grateful to receive notice of any new or old papers that the audience (users) think need to be included.

2013-05-01

Volunteers are integral to the history of hospices and continue to play a vital role. However, economic, policy and demographic challenges in the twenty-first century raise questions about how best to manage this essential resource. This narrative review explores the recent literature on end-of-life care volunteering and reflects upon the issues pertinent to current organisational challenges and opportunities. The parameters of the review were set deliberately wide in order to capture some of the nuances of contemporary volunteer practices. Articles reporting on research or evaluation of adult end-of-life care services (excluding prison services) that use volunteers and were published in English between 2000 and 2011 were included. Seven electronic databases, key journals and grey literature databases. Sixty-eight articles were included in the analysis. The articles were drawn from an international literature, while acknowledging that volunteer roles vary considerably by organisation and/or by country and over time. The majority of articles were small in scale and diverse in methodology, but the same topics repeatedly emerged from both the qualitative and quantitative data. The themes identified were individual volunteer factors (motivation, characteristics of volunteers, stress and coping, role boundaries and value) and organisational factors (recruiting for diversity, support and training and volunteers' place in the system). The tensions involved in negotiating the boundary spaces that volunteers inhabit, informality and regulation, diversity issues and the cultural specificity of community models, are suggested as topics that merit further research and could contribute to the continuing development of the volunteer workforce.

Mapping the literature of dental assisting.

The purpose of this study was to identify core journals and the databases that provide access to these journals for the field of dental assisting. This study was completed as a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the literature of allied health. There were three original journals selected for analysis using the prescribed methodology, Dental Assistant, the journal of the American Dental Assistants Association; Journal of the CDAA, the journal of the Canadian Dental Assistants' Association; and Dental Teamwork, published by the American Dental Association. Dental Teamwork ceased publication in December 1996; however, it was considered a necessary part of the analysis due to its extensive coverage of dental assisting as well as its numerous scientific articles with references. In Dental Assistant, there were 16 source articles, containing 206 citations. In Dental Teamwork, there were 31 source articles with 308 citations. In Journal of the CDAA, there were only 3 source articles with 14 citations. Bradford's Law of Scattering was applied to the journal citations. Four databases, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE/Excerpta Medica, and HEALTH were analyzed for their coverage of these cited journals. This study may encourage the dental assisting profession to take a close look at its existing journals and to consider enhancing the content of these journals or the publication of additional journals in the field. Dental assistants of today need substantive literature that deals with all aspects of their chosen profession in order to meet the challenges of providing dental health care in the future.

Information prescriptions, 1930–2013: an international history and comprehensive review*

PubMed Central

McKnight, Michelynn

2014-01-01

Objectives: Recently, government agencies in several countries have promoted information prescription programs to increase patients' understanding of their conditions. The practice has a long history and many publications, but no comprehensive literature reviews such as this. Methods: Using a variety of high-precision and high-recall strategies, the researcher searched two dozen online bibliographic databases, citation databases, and repositories, as well as many print sources, to identify and retrieve documents for review. Of these documents, ninety relevant English-language case reports, research reports, and reviews published from 1930–2013 met the study criteria. Results: Early to mid-twentieth century reports covered long-standing practices and used no rigorous research methods. The literature since the mid-1990s reports on short-term trial projects, especially of government-sponsored programs in the United States and United Kingdom. Although the concept of information prescription has been in the literature and practiced for decades, no long-term research studies were found. Conclusions: Most of the literature is anecdotal concerning small pilot projects. The reports investigate physician, patient, and librarian satisfaction but not changes in patient knowledge or behavior. Many twenty-first century projects emphasize materials and projects from specific government agencies and commercial enterprises. Implications: While the practice is commonly believed to be a good idea and there are many publications on the subject, few studies provide any evidence of the efficacy of information prescriptions for increased patient knowledge. Well-designed and executed large or long-term studies might produce needed evidence for professional practice. PMID:25349545

To review systematically the literature on female urethral injuries associated with pelvic fracture and to determine the optimum management of this rare injury. Using Meta-analysis of Observational Studies in Epidemiology criteria, we searched the Cochrane, Pubmed and OVID databases for all articles available before 30 June 2016 using the terms 'female pelvic fracture urethroplasty', 'female urethral distraction', 'female pelvic fracture urethral injury' and 'female pelvic fracture urethra girls.' Two authors of this paper independently reviewed the titles, abstracts, and articles in duplicate. We identified 162 individual articles from the databases. Fifty-one articles met our criteria for full review, including 158 female patients with urethral trauma. Of these injuries, 83 (53%) were managed with immediate repair; 17/83 (20%) via primary alignment and 66/83 (80%) via anastomotic repair. The remaining 75/158 (47%) were managed with delayed repair. Rates of urethral stenosis and fistula were highest after primary alignment. Urethral integrity appears to be similar after both primary anastomosis and delayed repair; however, patients experienced significantly more incontinence and vaginal stenosis after delayed repair. Patients who underwent delayed urethral repair were more likely to undergo more extensive reconstructive surgery than those who underwent primary repair. The optimum management of female urethral distraction defects is based on very-low-quality literature. Based on our review of the available literature, primary anastomotic repair of a female urethral distraction defect via a vaginal approach as soon as the patient is haemodynamically stable appears to be optimal. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Grant, Joan S; Graven, Lucinda J

2018-04-01

The purpose of this review was to examine and synthesize recent literature regarding problems experienced by informal caregivers when providing care for individuals with heart failure in the home. Integrative literature review. A review of current empirical literature was conducted utilizing PubMed, CINAHL, Embase, Sociological Abstracts, Social Sciences Full Text, PsycARTICLES, PsycINFO, Health Source: Nursing/Academic Edition, and Cochrane computerized databases. 19 qualitative, 16 quantitative, and 2 mixed methods studies met the inclusion criteria for review. Computerized databases were searched for a combination of subject terms (i.e., MeSH) and keywords related to informal caregivers, problems, and heart failure. The title and abstract of identified articles and reference lists were reviewed. Studies were included if they were published in English between January 2000 and December 2016 and examined problems experienced by informal caregivers in providing care for individuals with heart failure in the home. Studies were excluded if not written in English or if elements of caregiving in heart failure were not present in the title, abstract, or text. Unpublished and duplicate empirical literature as well as articles related to specific end-stage heart failure populations also were excluded. Methodology described by Cooper and others for integrative reviews of quantitative and qualitative research was used. Quality appraisal of the included studies was evaluated using the Joanna Briggs Institute critical appraisal tools for cross-sectional quantitative and qualitative studies. Informal caregivers experienced four key problems when providing care for individuals with heart failure in the home, including performing multifaceted activities and roles that evolve around daily heart failure demands; maintaining caregiver physical, emotional, social, spiritual, and financial well-being; having insufficient caregiver support; and performing caregiving with uncertainty and inadequate knowledge. Informal caregivers of individuals with heart failure experience complex problems in the home when providing care which impact all aspects of their lives. Incorporating advice from informal caregivers of individuals with heart failure will assist in the development of interventions to reduce negative caregiver outcomes. Given the complex roles in caring for individuals with heart failure, multicomponent interventions are potentially promising in assisting informal caregivers in performing these roles.

Brazil has sought to use economic evaluation to support healthcare decision-making processes. While a number of health economic evaluations (HEEs) have been conducted, no study has systematically reviewed the quality of Brazilian HEE. The objective of this systematic review was to provide an overview regarding the state of HEE research and to evaluate the number, characteristics, and quality of reporting of published HEE studies conducted in a Brazilian setting. We systematically searched electronic databases (MEDLINE, EMBASE, Latin American, and Caribbean Literature on Health Sciences Database, Scientific Electronic Library Online, NHS Economic Evaluation Database, health technology assessment Database, Bireme, and Biblioteca Virtual em Saúde Economia da Saúde ); citation indexes (SCOPUS, Web of Science), and Sistema de Informação da Rede Brasileira de Avaliação de Tecnologia em Saúde . Partial and full HEEs published between 1980 and 2013 that referred to a Brazilian setting were considered for inclusion. In total, 535 studies were included in the review, 36.8% of these were considered to be full HEE. The category of healthcare technologies more frequently assessed were procedures (34.8%) and drugs (28.8%) which main objective was treatment (72.1%). Forty-four percent of the studies reported their funding source and 36% reported a conflict of interest. Overall, the full HEE quality of reporting was satisfactory. But some items were generally poorly reported and significant improvement is required: (1) methods used to estimate healthcare resource use quantities and unit costs, (2) methods used to estimate utility values, (3) sources of funding, and (4) conflicts of interest. A steady number of HEE have been published in Brazil since 1980. To improve their contribution to inform national healthcare policy efforts need to be made to enhance the quality of reporting of HEEs and promote improvements in the way HEEs are designed, implemented (i.e., using sound methods for HEEs) and reported.

The Listeria monocytogenes strain 10403S BioCyc database.

Orsi, Renato H; Bergholz, Teresa M; Wiedmann, Martin; Boor, Kathryn J

2015-01-01

Listeria monocytogenes is a food-borne pathogen of humans and other animals. The striking ability to survive several stresses usually used for food preservation makes L. monocytogenes one of the biggest concerns to the food industry, while the high mortality of listeriosis in specific groups of humans makes it a great concern for public health. Previous studies have shown that a regulatory network involving alternative sigma (σ) factors and transcription factors is pivotal to stress survival. However, few studies have evaluated at the metabolic networks controlled by these regulatory mechanisms. The L. monocytogenes BioCyc database uses the strain 10403S as a model. Computer-generated initial annotation for all genes also allowed for identification, annotation and display of predicted reactions and pathways carried out by a single cell. Further ongoing manual curation based on published data as well as database mining for selected genes allowed the more refined annotation of functions, which, in turn, allowed for annotation of new pathways and fine-tuning of previously defined pathways to more L. monocytogenes-specific pathways. Using RNA-Seq data, several transcription start sites and promoter regions were mapped to the 10403S genome and annotated within the database. Additionally, the identification of promoter regions and a comprehensive review of available literature allowed the annotation of several regulatory interactions involving σ factors and transcription factors. The L. monocytogenes 10403S BioCyc database is a new resource for researchers studying Listeria and related organisms. It allows users to (i) have a comprehensive view of all reactions and pathways predicted to take place within the cell in the cellular overview, as well as to (ii) upload their own data, such as differential expression data, to visualize the data in the scope of predicted pathways and regulatory networks and to carry on enrichment analyses using several different annotations available within the database. © The Author(s) 2015.

2017-01-01

Strong growth of interdisciplinary sciences might find exceptional example in academic health economics. We decided to observe the quantitative output in this science since the beginning of the twenty-first century. Electronic search of the published literature was conducted in four different databases: one medical database-MEDLINE/PubMed, two general databases-Scopus/Elsevier and Web of Science (WoS), and one specialized health economic database-NHS Economic Evaluation Database (EED). The applied combination of key words was carefully chosen to cover the most commonly used terms in titles of publications dealing with conceptual areas of health economics. All bibliographic units were taken into account. Within the time horizon from January 1, 2000 to December 31, 2016, without language or limitations on bibliographic unit types, we identified an output ranging approximately from 60,345 to 88,246 records with applied search strategy in MEDLINE/PubMed, Scopus/Elsevier, and WoS. In NHS EED, we detected 14,761 records of economic evaluations of health interventions during the period in which database was maintained and regularly updated. With slightly more than one-third of the identified records, USA clearly dominates in this field. United Kingdom takes a strong second place with about 12% of identified records. Consistently, USA and UK universities are the most frequent among the top 15 affiliations/organizations of the authors of the identified records. Authors from Harvard University contributed to the largest number of the identified records. There is a clear evidence of both the upward stream of blossoming in health economics publications and its acceleration. Based on this bibliographic data set, it is difficult to distinguish the actual impact growth of this output provided dominantly by academia with modest contribution by pharmaceutical/medicinal device industry and diverse national government-based agencies. Further insight into the citation track record of these individual publications could provide helpful upgrade and a perspective on ongoing development.

The effectiveness of telephone counselling in the treatment of illicit drug and alcohol use concerns.

2016-03-01

Technology-assisted substance use interventions such as 'high-tech' internet-based treatments are thought to be effective; however, the relatively 'low-tech' use of telephone counselling does not yet have an established evidence base. This paper reviews the literature including articles with information on the use of telephone counselling for the treatment of illicit drug or alcohol use. A systematic literature search using a set of telephone counselling and substance-related terms was conducted across four electronic databases. English studies prior to June 2014 that involved the use of telephone counselling with the treatment of illicit drug or alcohol use as a primary or secondary outcome were included. Review papers, opinion pieces, letters or editorials, case studies, published abstracts, and posters were excluded. In all, 94 publications were included in the review. The literature was supportive of telephone counselling for the treatment of alcohol use in the short term; however, literature regarding illicit drug use was particularly scarce. The generalisability of findings was limited by evident methodological issues in the included studies. © The Author(s) 2015.

Clinical trials and randomized clinical trials, as well as literature reviews published in English, French and German will be analyzed. Counseling is a part of the non-pharmacological management of chronic illnesses such as multiple sclerosis. Symptoms' diversity and the different clinical forms limit standardized programs of self-care management, applicable to patients. In the literature review, counseling programs have often low metrology. A behavior change with patients and medical staff could exist. To empower the patient, to reduce symptoms' impact and to improve treatment access are the aims of educational therapy. Therapeutic education program for multiple sclerosis patients could progress with their standardization and assessment, for each sign. To promote the educational therapy of multiple sclerosis patients, a specific training for medical staff, as specific financing are necessary. 2011 Elsevier Masson SAS. All rights reserved.

Given recent, rapid growth in the field of women veterans' mental health, the goal of this review was to update the status of women veterans' mental health research and to identify current themes in this literature. The scope of this review included women veterans' unique mental health needs, as well as gender differences in veterans' mental health needs. Database searches were conducted for relevant articles published between January 2008 and July 2011. Searches were supplemented with bibliographic reviews and consultation with subject matter experts. The database search yielded 375 titles; 32 met inclusion/exclusion criteria. The women veterans' mental health literature crosses over several domains, including prevalence, risk factors, health care utilization, treatment preferences, and access barriers. Studies were generally cross-sectional, descriptive, mixed-gender, and examined Department of Veterans Affairs (VA) health care users from all service eras. Results indicate higher rates of specific disorders (e.g., depression) and comorbidities, with differing risk factors and associated medical and functional impairment for female compared with male veterans. Although satisfaction with VA health care is generally high, unique barriers to care and indices of treatment satisfaction exist for women. There is a breadth of descriptive knowledge in many content areas of women veterans' mental health; however, the research base examining interventional and longitudinal designs is less developed. Understudied content areas and targets for future research and development include certain psychiatric disorders (e.g., schizophrenia), the effects of deployment on woman veterans' families, and strategies to address treatment access, attrition, and provision of gender-sensitive care.

Bibliometrics is defined as the use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Our objective was to characterize Spanish scientific output in Dentistry through the analysis of Web of Science database in a 20-year period. By means of a bibliometric study documents were statistically analyzed using indicators that showed quantitative and qualitative aspects of the production. Specifically, time course of the scientific production within the time span was analysed, as were the journals where the article was published and the categories of Journal Citation Reports (JCR) in which they belong, thematic areas, authorship, and finally authors and institutions with the highest production in Spain. By means of the design of a specific search strategy previously described in the scientific literature, we recovered all citable documents about Dentistry signed by Spanish researchers and included in the WoS database between 1993 and 2012. A total of 3006 documents fulfilled the search criteria, of which 2449 (81.5%) were published in journals within the category Dentistry Oral Surgery and Medicine and 557 (18.5%) within other categories of the JCR. During the four quinquenniums studied, the production increased quantitatively (8.6-fold) and qualitatively. Finally, the universities of Granada and Complutense of Madrid were the institutions with the highest production and most prolific authors. The Spanish dental production sharply increased in the last two decades, reaching quantitative and qualitative levels similar to those of the other medical specialties in the country.

Researchers are confronted to numerous definitions of work ability/disability, influenced by their context of emergence, discipline, purpose, underlying paradigm and relationship to time. This study provides an in-depth analysis of the concept through a systematic scoping review and the development of an integrative concept map of work (dis)ability. The research questions are: How has work (dis)ability been conceptualized from the perspectives of research, practice, policy and industry in the published scientific literature? How has the conceptualization of work (dis)ability evolved over time? A search strategy was designed with a library scientist to retrieve scientific publications containing explicit definition(s) of work (dis)ability in leading-edge databases. The screening and the extraction of the definitions were achieved by duplicate assessment. The definitions were subject to a comparative analysis based on the grounded theory approach. In total, 423 abstracts were retrieved from the bibliographic databases. After removing duplicates, 280 unique records were screened for inclusion. A final set of 115 publications containing unique original conceptual definitions served as basis for analysis. The scientific literature does not reflect a shared, integrated vision of the exact nature and dimensions of work (dis)ability. However, except for a few definitions, there seems to be a consensus that work (dis)ability is a relational concept resulting from the interaction of multiple dimensions that influence each other through different ecological levels. The conceptualization of work (dis)ability also seems to have become more dynamic over time. The way work (dis)ability is defined has important implications for research, compensation and rehabilitation.
