AIM: The aim of this study was to show how to verify plagiarism of the paper written in Macedonian and translated in foreign language. MATERIAL AND METHODS: Original article “Ethics in Medical Research Involving Human Subjects”, written in Macedonian, was submitted as an assay-2 for the subject Ethics and published by Ilina Stefanovska, PhD candidate from the Iustinianus Primus Faculty of Law, Ss Cyril and Methodius University of Skopje (UKIM), Skopje, Republic of Macedonia in Fabruary, 2013. Suspected article for plagiarism was published by Prof. Dr. Gordana Panova from the Faculty of Medical Sciences, University Goce Delchev, Shtip, Republic of Macedonia in English with the identical title and identical content in International scientific on-line journal “SCIENCE & TECHNOLOGIES”, Publisher “Union of Scientists - Stara Zagora”. RESULTS: Original document (written in Macedonian) was translated with Google Translator; suspected article (published in English pdf file) was converted into Word document, and compared both documents with several programs for plagiarism detection. It was found that both documents are identical in 71%, 78% and 82%, respectively, depending on the computer program used for plagiarism detection. It was obvious that original paper was entirely plagiarised by Prof. Dr. Gordana Panova, including six references from the original paper. CONCLUSION: Plagiarism of the original papers written in Macedonian and translated in other languages can be verified after computerised translation in other languages. Later on, original and translated documents can be compared with available software for plagiarism detection. PMID:27275319

We review and comment original articles published in the main peer reviewed journals between September 2015 and September 2016 on hypertension, with relevance and potential impact in clinical practice. The selection of the original papers has been necessarily limited and subjective, given the extremely high volume of publications over the period. Some large clinical trials such as SPRINT, HOPE3 or PATHWAY-2, epidemiological studies, cohort studies or studies about ambulatory blood pressure evaluation are discussed. Aspects of the target blood pressure level and treatment are also discussed. In all cases, we present the new evidences on the diagnosis, evaluation and therapeutic management of hypertension published in the last year. Our goal is to motivate thorough reading of the originals that can only be commented briefy here. © 2017 SEHLELHA. Published by Elsevier España, S.L.U. All rights reserved.

To determine methodological quality of therapy articles published in Cirugía Española and to study its association with the publication year, the centre of origin and subjects. A literature study which included all therapy articles published between 2005 and 2008. All kinds of clinical designs were considered, excluding editorials, review articles, letters to editor and experimental studies. Variables analysed included: year of publication, centre of origin, design, and methodological quality of articles. A valid and reliable scale was applied to determine methodological quality. A total of 243 articles [206 series of cases (84.8%), 27 cohort studies (11.1%), 9 clinical trials (3.7%) and 1 case control study (0.4%)] were found. Studies came preferentially from Catalonia and Valencia (22.3% and 12.3% respectively). Thematic areas most frequently found were hepato-bilio-pancreatic and colorectal surgery (20.0% and 16.6%, respectively). Average and median of the methodological quality score calculated for the entire series were 9.5+/-4.3 points and 8 points, respectively. Association between methodological quality and geographical area (p=0.0101), subject area (p=0.0267), and university origin (p=0.0369) was found. A significant increase of methodological quality by publication year was observed (p=0.0004). Methodological quality of therapy articles published in Cirugía Española between 2005 and 2008 is low; but an increase tendency with statistical significance was observed.

2015-01-01

This study takes a stratified random sample of articles published in 2014 from the top 10 journals in the disciplines of biology, chemistry, mathematics, and physics, as ranked by impact factor. Sampled articles were examined for their reporting of original data or reuse of prior data, and were coded for whether the data was publicly shared or otherwise made available to readers. Other characteristics such as the sharing of software code used for analysis and use of data citation and DOIs for data were examined. The study finds that data sharing practices are still relatively rare in these disciplines' top journals, but that the disciplines have markedly different practices. Biology top journals share original data at the highest rate, and physics top journals share at the lowest rate. Overall, the study finds that within the top journals, only 13% of articles with original data published in 2014 make the data available to others.

The acceptance of a paper in a top-ranked journal depends on the importance of the study, and should not depend on its country of origin. If the papers' citation rate is a proxy for their importance, and the threshold for acceptance is unrelated to the country of origin, papers from different countries published in the same journal should have a similar number of citations. Conversely, if the threshold is lowered for some countries, their papers will have a lower mean citation rate. The number of citations and the corresponding author's country were obtained for 4724 papers published between 1998 and 2002 in the British Medical Journal, the Lancet, Journal of the American Medical Association and New England Journal of Medicine. Countries were grouped according to the World Bank classification and geographical location: low-middle income countries; high-income European countries; high-income non-European countries; UK and USA. The probability of papers being poorly cited by country of origin was estimated, using domestic papers (British papers published in British journals and US papers published in US journals) as the reference. Compared with domestic papers, the OR of being poorly cited was 0.67 (95% CI 0.55 to 0.81) for papers from high-income European countries, 0.97 (0.76 to 1.24) for papers from high-income non-European countries and 1.93 (1.28 to 2.89) for papers from low-middle income countries. Papers from different countries published in the same journal have different citation rates. This may reflect difficulties for researchers from some countries to publish their research in leading medical journals.

2014-01-01

Objective To study journals' responses to a request from the State Medical Association of Rheinland-Pfalz, Germany, to retract 88 articles due to ethical concerns, and to check whether the resulting retractions followed published guidelines. Design Descriptive cross-sectional study. Population 88 articles (18 journals) by the anaesthesiologist Dr. Boldt, that warranted retraction. Method According to the recommendations of the Committee on Publication Ethics, we regarded a retraction as adequate when a retraction notice was published, linked to the retracted article, identified the title and authors of the retracted article in its heading, explained the reason and who took responsibility for the retraction, and when the retracted article was freely accessible and marked using a transparent watermark that preserved original content. Two authors extracted data independently (January 2013) and contacted editors-in-chief and publishers for clarification in cases of inadequate retraction. Results Five articles (6%) fulfilled all criteria for adequate retraction. Nine (10%) were not retracted (no retraction notice published, full text article not marked). 79 (90%) retraction notices were published, 76 (86%) were freely accessible, but only 15 (17%) were complete. 73 (83%) full text articles were marked as retracted, of which 14 (16%) had an opaque watermark hiding parts of the original content, and 11 (13%) had all original content deleted. 59 (67%) retracted articles were freely accessible. One editor-in-chief stated personal problems as a reason for incomplete retractions, eight blamed their publishers. Two publishers cited legal threats from Dr. Boldt's co-authors which prevented them from retracting articles. Conclusion Guidelines for retracting articles are incompletely followed. The role of publishers in the retraction process needs to be clarified and standards are needed on marking retracted articles. It remains unclear who should check that retractions are done properly. Legal safeguards are required to allow retraction of articles against the wishes of authors. PMID:24465744

Randomized trials published in Chinese or Western journals: comparative empirical analysis.

Purgato, Marianna; Cipriani, Andrea; Barbui, Corrado

A major concern to the inclusion in systematic reviews of studies originating in China and published in Chinese journals refers to the quality of study reporting. In this systematic survey of randomized trials, we compared the characteristics of studies published in Chinese journals with those of studies published in Western journals. We included 69 studies comparing citalopram with other antidepressant drugs in the treatment of major depression. Of these, 37 (54%) were published in Chinese journals. The standard of reporting was generally poor in both Western and Chinese studies. In some Chinese studies, the generation of the randomization sequence raised concern about their experimental nature, and in almost all included studies, the concealment of allocation was not properly described. Blinding was seldom adopted in Chinese studies, and the risk of sponsorship bias was uncertain because Chinese studies did not report any financial support. In most Western studies, outcome data were selectively and incompletely reported. Pooling together all trials revealed that citalopram was similarly effective in comparison with all other antidepressant drugs both in Western studies (standardized mean difference, -0.04; 95% confidence interval, -0.15 to 0.06) and in Chinese studies (standardized mean difference, -0.08, 95% confidence interval, -0.18 to 0.02). Randomized controlled trials published in Chinese journals represent most of the studies included in this review. This suggests that omitting to search biomedical databases originating from China would systematically exclude a relevant proportion of randomized trials published in Chinese journals, with a risk of random error or bias. The increasing inclusion of Chinese studies in systematic reviews reinforces the need to check the quality of randomized trials that are meta-analyzed.

Advancement of knowledge requires presentation and publication of high-quality scientific research. Studies submitted for presentation undergo initial peer review before acceptance and the rate of subsequent publication may be taken as an indicator of access to publication for pediatric radiology studies. Evaluate the proportion of abstracts also published in journals for pediatric radiology conferences and identify factors associated with publication success. All Medline articles that originated from oral presentations at the European Society for Paediatric Radiology (ESPR), the Society for Pediatric Radiology (SPR) or the International Pediatric Radiology (IPR) conferences between 2010 - 2012 were evaluated. Descriptive statistics to evaluate published and unpublished groups were calculated overall and split by characteristics of the abstracts such as number of authors. Overall number of abstracts published was 300/715 (41.9%), with most articles published in radiology specific journals (181/300; 60.3%), with median impact factor 2.31 (interquartile range [IQR]: 1.65-3.14, range: 0-18.03). Those published after the conference (262/300, 87.6%) had a median time to publication of 18 months and for those published before, the median time was -11 months. Median sample size in published articles was 52 (IQR: 33-105, range: 1-6,351). Of pediatric radiology oral abstracts, 41.9% achieve publication after a period of at least 3 years from presentation. Studies originating from certain countries and on certain subspecialty topics were more likely to get published.

To compare the scientific methodology and quality of articles published in Anales Españoles de Pediatría and Medicina Clínica. A stratified and randomized selection of 40 original articles published in 2001 in Anales Españoles de Pediatría and Medicina Clínica was made. Methodological errors in the critical analysis of original articles (21 items), epidemiological design, sample size, statistical complexity and levels of scientific evidence in both journals were compared using the chi-squared and/or Student's t-test. No differences were found between Anales Españoles de Pediatría and Medicina Clínica in the critical evaluation of original articles (p > 0.2). In original articles published in Anales Españoles de Pediatría, the designs were of lower scientific evidence (a lower proportion of clinical trials, cohort and case-control studies) (17.5 vs 42.5 %, p 0.05), sample sizes were smaller (p 0.003) and there was less statistical complexity in the results section (p 0.03). To improve the scientific quality of Anales Españoles de Pediatría, improved study designs, larger sample sizes and greater statistical complexity are required in its articles.

Falagas, M E; Alexiou, V G

There is an ongoing discussion in the scientific community that even the leading scientific journals publish mainly research that is produced in the countries where these journals are based. We analysed data regarding the origin of publications in 11 leading general medical journals during the last 35 years: The Lancet, British Medical Journal, Journal of the American Medical Association, New England Journal of Medicine, Annals of Internal Medicine, Archives of Internal Medicine, American Journal of Medicine, Mayo Clinic Proceedings, Canadian Medical Association Journal, Medical Journal of Australia and Journal of Internal Medicine (previously called Acta Medica Scandinavica). Among the examined journals, The Lancet has been the most diverse regarding the origin of publications; in the period 1971-1975, 62.6% of its publications originated from the UK while the relevant figure dropped to 43.2% in the period 2001-2005 (19.4% decrease). During the period 2000-2005, the proportion of publications that originated from the country in which each one of the rest of the examined journals has been based ranged from 71.7% to 95.1%. This figure decreased by a proportion ranging from 10.9% to 19.4% for some major US- and UK-based medical journals during the 35-year study period. Our own interpretation of the findings of this study is that scientific journals will better serve the global scientific community as well as the public by adopting policies that increase the mixture of the origin of research that they publish, including work from scientists in developing countries, especially during the era we live.

A quantitative analysis of qualitative studies in clinical journals for the 2000 publishing year

McKibbon, Kathleen Ann; Gadd, Cynthia S

2004-01-01

Background Quantitative studies are becoming more recognized as important to understanding health care with all of its richness and complexities. The purpose of this descriptive survey was to provide a quantitative evaluation of the qualitative studies published in 170 core clinical journals for 2000. Methods All identified studies that used qualitative methods were reviewed to ascertain which clinical journals publish qualitative studies and to extract research methods, content (persons and health care issues studied), and whether mixed methods (quantitative and qualitative methods) were used. Results 60 330 articles were reviewed. 355 reports of original qualitative studies and 12 systematic review articles were identified in 48 journals. Most of the journals were in the discipline of nursing. Only 4 of the most highly cited health care journals, based on ISI Science Citation Index (SCI) Impact Factors, published qualitative studies. 37 of the 355 original reports used both qualitative and quantitative (mixed) methods. Patients and non-health care settings were the most common groups of people studied. Diseases and conditions were cancer, mental health, pregnancy and childbirth, and cerebrovascular disease with many other diseases and conditions represented. Phenomenology and grounded theory were commonly used; substantial ethnography was also present. No substantial differences were noted for content or methods when articles published in all disciplines were compared with articles published in nursing titles or when studies with mixed methods were compared with studies that included only qualitative methods. Conclusions The clinical literature includes many qualitative studies although they are often published in nursing journals or journals with low SCI Impact Factor journals. Many qualitative studies incorporate both qualitative and quantitative methods. PMID:15271221

Ease of articulation: A replication.

PubMed

Shuster, Linda I; Cottrill, Claire

2015-01-01

Researchers, as well as the lay public and the popular press, have become increasingly concerned about the lack of reproducibility of research findings. Despite this concern, research has shown that replications of previously published work comprise a very small proportion of published studies. Moreover, there are fewer published direct replications of research studies by independent investigators, and this type of replication is much less likely to confirm the results of the original research than are replications by the original investigator or conceptual replications. A search of the communication disorders research literature reveals that direct replications by independent investigators are virtually non-existent. The purpose of this project was to describe the major issues related to research reproducibility and report the results of a direct replication of a study by Locke (1972) regarding ease of articulation. Two methods for rating ease of articulation were employed. We were able to reproduce the results of the original study for the first method, obtaining a moderate positive correlation between our rankings of phoneme difficulty and Locke's rankings. We obtained a very high positive correlation between our phoneme rankings and rankings obtained in the original study for the second method. Moreover, we found a higher correlation between difficulty rankings and order of speech sound acquisition for American English than was found in the original study. Direct replication is not necessary for all studies in communication disorders, but should be considered for high impact studies, treatment studies, and those that provide data to support models and theories. The reader will be able to: (1) describe the major concerns related to the replicability of research findings; (2) describe the status of research replications in communication disorders; (3) describe how ease of articulation may relate to the order of speech sound acquisition in children; (4) list some types/areas of research that might be candidates for replication in the field of communication disorders.

The present study aims to review all the major articles on respiratory sleep disorders, mechanical ventilation, and respiratory critical care published in the last year in Archivos de bronconeumología. Between December 2009 and November 2010, 15 studies on these topics were published in Archivos de bronconeumología. Ten of these studies dealt with respiratory sleep disorders, consisting of six original articles, one special article, one review article, one letter to the editor and one supplement on chronic obstructive pulmonary disease and its association with sleep apneas. Five articles were published on non-invasive mechanical ventilation: one editorial, one special article, one article in a supplement and two original articles. As in previous years, there was a marked difference in the number of articles published on non-invasive mechanical ventilation and sleep-apnea syndrome, with a greater number of articles being published on the latter. Although some articles highlight the importance of the place where ventilation is commenced, no study specifically dealing with intermediate care units was published in Archivos de bronconeumología in 2010. This absence could be interpreted as a result of the low implantation of this type of unit in Spain, contrasting with the high activity undertaken in this field by pneumology services.

ConformRank: A conformity-based rank for finding top-k influential users

NASA Astrophysics Data System (ADS)

Wang, Qiyao; Jin, Yuehui; Cheng, Shiduan; Yang, Tan

2017-05-01

Finding influential users is a hot topic in social networks. For example, advertisers identify influential users to make a successful campaign. Retweeters forward messages from original users, who originally publish messages. This action is referred to as retweeting. Retweeting behaviors generate influence. Original users have influence on retweeters. Whether retweeters keep the same sentiment as original users is taken into consideration in this study. Influence is calculated based on conformity from emotional perspective after retweeting. A conformity-based algorithm, called ConformRank, is proposed to find top-k influential users, who make the most users keep the same sentiment after retweeting messages. Emotional conformity is introduced to denote how users conform to original users from the emotional perspective. Conforming weights are introduced to denote how two users keep the same sentiment after retweeting messages. Emotional conformity is applied for users and conforming weights are used for relations. Experiments were conducted on Sina Weibo. Experimental results show that users have larger influence when they publish positive messages.

The ability to reproduce experiments is a defining principle of science. Reproducibility of clinical research has received relatively little scientific attention. However, it is important as it may inform clinical practice, research agendas, and the design of future studies. We used scoping review methods to examine reproducibility within a cohort of randomized trials examining clinical critical care research and published in the top general medical and critical care journals. To identify relevant clinical practices, we searched the New England Journal of Medicine, The Lancet, and JAMA for randomized trials published up to April 2016. To identify a comprehensive set of studies for these practices, included articles informed secondary searches within other high-impact medical and specialty journals. We included late-phase randomized controlled trials examining therapeutic clinical practices in adults admitted to general medical-surgical or specialty intensive care units (ICUs). Included articles were classified using a reproducibility framework. An original study was the first to evaluate a clinical practice. A reproduction attempt re-evaluated that practice in a new set of participants. Overall, 158 practices were examined in 275 included articles. A reproduction attempt was identified for 66 practices (42%, 95% CI 33-50%). Original studies reported larger effects than reproduction attempts (primary endpoint, risk difference 16.0%, 95% CI 11.6-20.5% vs. 8.4%, 95% CI 6.0-10.8%, P = 0.003). More than half of clinical practices with a reproduction attempt demonstrated effects that were inconsistent with the original study (56%, 95% CI 42-68%), among which a large number were reported to be efficacious in the original study and to lack efficacy in the reproduction attempt (34%, 95% CI 19-52%). Two practices reported to be efficacious in the original study were found to be harmful in the reproduction attempt. A minority of critical care practices with research published in high-profile journals were evaluated for reproducibility; less than half had reproducible effects.

IntroductionPeripheral arterial disease (PAD) is being increasingly managed by endovascular therapies. In this study, we identified the clinical services publishing research as well as the journals of publication over a 5-year period.MethodsTwenty keywords and phrases related to endovascular intervention were identified, and a literature search was performed through the PubMed database from January 2009 to January 2014. Inclusion criteria were English language, study population more than five patients, and matching the keyword search. Eligible studies were collated into a database and classified by journal of publication, PubMed number, article title, publishing clinical service, type of publication, country of origin, andmore » authors.Results825 studies from 114 different journals were identified. 297 papers were excluded. Of the 528 included papers, 204 (39%) were published by Vascular Surgery (VS), 157 (30%) by Interventional Radiology (IR), 101 (19%) by Cardiology, 43 (8%) by Angiology, 6 (1%) by Vascular Medicine, and 17 (3%) from miscellaneous services. 283 (54%) studies originated from Europe, 157 (30%) from North America, 76 (14%) from Asia, 6 from Australia, 3 each from South America and Africa. IR published the most papers on PAD endovascular intervention in Europe with VS second while this trend was reversed in the USA. The 528 papers were published in 98 different journals with retrospective case series (72%), the majority.ConclusionIR continues to play a significant research role in endovascular intervention in PAD, particularly in Europe, and specifically in below the knee intervention, pedal intervention, and drug-eluting technologies.« less

Is structural stigma's effect on the mortality of sexual minorities robust? A failure to replicate the results of a published study.

PubMed

Regnerus, Mark

2017-09-01

The study of stigma's influence on health has surged in recent years. Hatzenbuehler et al.'s (2014) study of structural stigma's effect on mortality revealed an average of 12 years' shorter life expectancy for sexual minorities who resided in communities thought to exhibit high levels of anti-gay prejudice, using data from the 1988-2002 administrations of the US General Social Survey linked to mortality outcome data in the 2008 National Death Index. In the original study, the key predictor variable (structural stigma) led to results suggesting the profound negative influence of structural stigma on the mortality of sexual minorities. Attempts to replicate the study, in order to explore alternative hypotheses, repeatedly failed to generate the original study's key finding on structural stigma. Efforts to discern the source of the disparity in results revealed complications in the multiple imputation process for missing values of the components of structural stigma. This prompted efforts at replication using 10 different imputation approaches. Efforts to replicate Hatzenbuehler et al.'s (2014) key finding on structural stigma's notable influence on the premature mortality of sexual minorities, including a more refined imputation strategy than described in the original study, failed. No data imputation approach yielded parameters that supported the original study's conclusions. Alternative hypotheses, which originally motivated the present study, revealed little new information. Ten different approaches to multiple imputation of missing data yielded none in which the effect of structural stigma on the mortality of sexual minorities was statistically significant. Minimally, the original study's structural stigma variable (and hence its key result) is so sensitive to subjective measurement decisions as to be rendered unreliable. Copyright © 2016 The Author.

PSYCHOLOGY. Estimating the reproducibility of psychological science.

PubMed

2015-08-28

Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

The aim of this study was to analyse publication trends from the anaesthetic literature of the G-20 countries. We performed a literature search in Medline to identify articles related to anaesthetic departments published between 2001 and 2015, by specific G-20 countries according to the affiliation field of the authors, and to three time periods 2001-2005, 2006-2010 and 2011-2015. The number of articles, number of original articles (vs. reviews, editorials or correspondence), articles per million inhabitants, and citations per article were analysed. In total, 96,920 articles were published between 2001 and 2015 in 74 anaesthetic and in 4117 non-anaesthetic journals, with an increase of +104% absolute (i.e. from 23,028 in 2001-05 to 46,887 articles ìn 2010-15) and +85% as articles per million inhabitants. Similarly, the number of original articles increased by 21%, but the anaesthetic specialty's share of original articles (as a proportion of total articles in biomedicine) decreased from 31% in 2001-2005 to 19% in 2011-2015 (-38%). The USA published most articles (2011-15 16,016; 31% of total), second came the EU as a whole and third Japan (from 2001 to 2005) or Germany (2006-2010) until 2011-2015 when China took over the third rank. In 2011-2015, Canada published most articles per million inhabitants (68.7 articles/million inhabitants). China and India exhibited the most publication growth 11- and 9-fold, respectively, and are now among the top five countries for the number of published articles. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

Inherited color vision deficiencies (CVD) vary in prevalence by population and by sex. The most common CVD is X chromosome-linked anomalous trichromacy. Prevalence varies significantly by sex and race. The frequency of color vision defects in Saudi females has not been studied previously. This study surveyed the prevalence of congenital color vision defects in Saudi females of Arab origin. Seven thousand four hundred sixty-seven female subjects (N = 7,467) from the Kingdom of Saudi Arabia were screened using both Ishihara pseudoisochromatic plates and the Farnsworth Dichotomous test (D-15). CVD subjects were tested further with the Farnsworth-Munsell 100 Hue test. Of 7,467 female subjects tested, 26 subjects were found to have defective color vision, for a prevalence of 0.35%. Sixteen subjects had a deutan defect, and 10 had a protan defect. Arab females have significantly lower prevalence of CVD when compared with published data from females of other races. Analysis of the 5 regions of Saudi Arabia showed no significant difference between the regions. Prevalence of CVD among Saudi females of Arab origin is 0.35% and is among the lowest of all published data. Copyright © 2011 American Optometric Association. Published by Elsevier Inc.

2013-03-26

Whereas the most influential journals in psychiatry are English language journals, periodicals published in other languages serve an important purpose for local communities of clinicians and researchers. This study aimed at analyzing the scientific production and the recognition of non-English general psychiatry journals. In a cohort study, the 2009 volume of ten journals from Brazil (1), German language countries (5), France (2), Italy (1), and Poland (1) was searched for original articles. Patterns of citations to these articles during 2010 and 2011 as documented in Web of Science were analyzed. The journals published 199 original articles (range: 4-46), mostly observational studies. Half of the papers were cited in the following two years. There were 246 citations received, or an average of 1.25 cites per article (range: 0.25-4.04). Many of these citations came from the local community, that is, from the same authors and journals. Citations by other periodicals and other authors accounted for 36% [95%-CI: 30%-42%], citations in English sources for 33% [28%-39%] of all quotations. There was considerable heterogeneity with regard to citations received among the ten journals investigated. Non-English language general psychiatry journals contribute substantially to the body of research. However, recognition, and in particular recognition by the international research community is moderate.

Schreiber, K; Girard, T; Kindler, C H

2004-10-01

Molecular biology has expanded the horizons of anaesthesia during the last 20 years and has led to an increase of basic science articles that are published in the specialised anaesthetic journals or originate in anaesthetic institutions. We searched for and analysed the specific features, such as year of publication, publishing journal, and country of origin, of all such molecular biology articles stored in the MEDLINE database during the period 1986-2002. We identified 1265 original articles that used molecular biology techniques; 223 (18%) of these articles were published in anaesthetic journals and 1042 (82%) articles in 556 other biomedical journals. While in the late 1980s only a few molecular biology articles were published each year by anaesthetic institutions, worldwide this number reached approximately 200 basic science articles by the end of 2002. The USA clearly dominates the field of anaesthesia with respect to molecular biology research with 839 (66%) such articles.

Although analyses have been done on the publishing of scientific articles on pain in Spanish, book publications in the field have not been studied. This article fills that gap. A bibliography of books with pain approached from a medical standpoint was compiled from ISBN CD-ROM database (updated for 1993). Books going into more than one edition were considered single titles. Multi-volume collections were considered single books. We analyzed type of book, subject, ISBN classification, year, language (of publication and original), publisher and place of publication. Two hundred books were studied. Over 60% had been published within the previous 10 years. The year that showed the most books published was 1990 (19) followed by 1989 (16) and 1988 (16). Output has been rising steadily. One hundred ninety-eight books were published in Spanish and 2 in Catalan. The original language was Spanish in 114 cases, English in 51 cases, French in 21 and German in 7. By ISBN classification, most (146) covered pathology, disease and medical/therapeutic clinical practice. By topic, 51 books were general, 41 treated lumbalgia, sciatica or back pain and 35 covered headaches in general or migraine. Most of the books were issued by trade publishers. The cities most often involved were Barcelona and Madrid. An increased number of books about pain are being published in Spain, coinciding with a rise in the publication of scientific articles on the subject.

A correctly drafted original article gives information on what was done, why it was done, how it was done, the result of what was done, and the significance of what was done. Many articles fail to report their results effectively. To describe the characteristics of an original article and to give practical recommendations to prevent the most common errors in our environment. We performed a systematic search of the terms "how to write a scientific article", "structure of the original article" and "publishing an article" in the databases PubMed and SCOPUS. We analysed the structure of an original article and the characteristics of its parts and prepared advice on the publication of an article. The journal's guidelines for authors should be read. It is usual for the original article to follow the IMRAD structure: Introduction, Methods, Results and Discussion. The introduction states briefly why the study was performed. The methods' section should give a detailed explanation of how the study was performed. The results should be clearly presented, with the help of tables, without repeating information. The discussion explains the relevance of the results and contrasts them with those of other authors. Any limitations and a conclusion supported by the results must be included. Writing an original article correctly requires practice and it must be supported by a good research work in order to be published. Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U.

Regulatory Considerations of Bioequivalence Studies for Oral Solid Dosage Forms in Japan.

PubMed

Kuribayashi, Ryosuke; Takishita, Tomoko; Mikami, Kenichi

2016-08-01

Bioequivalence (BE) studies are used to infer the therapeutic equivalence of generic drug products to original drug products throughout the world. In BE studies, bioavailability (BA) should be compared between the original and generic drug products, with BA defined as the rate and extent of absorption of active pharmaceutical ingredients or active metabolites from a product into the systemic circulation. For most of BE studies conducted during generic drug development, BA comparisons are performed in single-dose studies. In Japan, the revised "Guideline for Bioequivalence Studies of Generic Products" was made available in 2012 by the Ministry of Health, Labour, and Welfare, and generic drug development is currently conducted based on this guideline. Similarly, the U.S. Food and Drug Administration and European Medicines Agency have published guidance and guideline on generic drug development. This article introduces the guideline on Japanese BE studies for oral solid dosage forms and the dissolution tests for the similarity and equivalence evaluation between the original and generic drug products. Additionally, we discuss some of the similarities and differences in guideline between Japan, the United States, and the European Union. Copyright © 2016 American Pharmacists Association®.

The MECP2 mutations occurring in the severe neurological disorder Rett syndrome are predominantly de novo, with rare familial cases. The aims of this study were to provide a precise estimate of the parental origin of MECP2 mutations using a large Chinese sample and to assess whether parental origin varied by mutation type. The parental origin was paternal in 84/88 [95.5%, (95% confidence interval 88.77-98.75)] of sporadic Chinese cases. However, in a pooled sample including data from the literature the spectrum of mutations occurring on maternally and paternally derived chromosomes differed significantly. The excess we found of 'single base pair gains or losses' on maternally derived MECP2 gene alleles suggests that this mutational category is associated with an elevated risk of gonadal mosaicism, which has implications for genetic counseling. © 2011 John Wiley & Sons A/S.

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.

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

Publications are the primary output of scientific research. We conducted a national study to quantify Algerian medical teachers' research output and identify its determinants during the 2000-2009 decade. The American Medline database and the French Pascal database were used. A publication was eligible only if the lead author was an Algerian medical teacher (in medicine, pharmacy, or dentistry) working in Algeria. The same questionnaire was completed by cases (teachers who were first authors of an original article during the study period) and randomly selected controls. Logistic regression analysis was used to identify factors related to research output. A total of 79 original articles (42.2% of publications) were retrieved, a quarter of which were listed in Pascal alone. The publication rate was 2.6 original articles per 1000 teachers per year. The journals that published these original articles had a median impact factor of 0.83. The ability to publish an original article was 4.3 times higher if the teacher had undergone training in biostatistics and/or epidemiology (adjusted odds ratio [aOR]=4.31, 95% confidence interval [CI]: 1.79-10.38). A promotion evaluation grid that did not encourage writing (aOR=3.44, 95% CI: 1.42-8.33), a doctoral thesis, seniority, foreign collaboration, and English language proficiency were found to be associated with publication output. Algerian medical teachers' research output was particularly low. Replacing the current promotion grid with a grid that promotes writing, developing abilities to read and write articles and developing English language proficiency are likely to improve this situation.

To study changes in authorship, interval between acceptance and publication, and bibliographic references of original articles published in Revista Española de Enfermedades Digestivas (REED) between 1993 and 1998. This was a descriptive retrospective study of 359 original research articles published in REED between 1993 and 1998. The variables assessed were: number of authors (author/article index), interval between acceptance of the manuscript and publication in the journal, and degree of obsolescence of articles based on the age of the references cited (Burton-Kleber and Price indexes). The author/article index was 6.1, and increased from 5.9 in 1993 to 6.5 in 1998. The interval between acceptance and publication increased from 251 days to 436 days in this period (p < 0.0001). English was the language of publication used most commonly, followed by Spanish (10.7%). Citations to Spanish references decreased from 12.5% in 1993 to 8.7% in 1998. The half-life of articles was 7 years, and Price index was 41.5%. REED's bibliometric characteristics are similar to those of other national journals, but this study shows changes in bibliographic indicators from 1993 to 1998; increases in the number of authors per article, the interval to publication, the use of foreign references and the degree of obsolescence.

Despite increasing numbers of women attending medical school and completing residencies, women continue to lag behind men in academic achievement. Other specialties have found that women publish fewer journal articles than men. While family medicine is becoming increasingly gender balanced, the aim of this study was to evaluate the gender balance of published material within family medicine journals. All original articles were reviewed in five family medicine journals published in the United States (Family Medicine, Journal of Family Practice, Journal of the American Board of Family Medicine, Annals of Family Medicine, and American Family Physician) between 2006-2008. The articles were categorized based on type of publication and gender of first author. The editorial boards of each of the journals were examined to determine gender breakdown. A total of 2,126 articles were included in the study. Females were first author on 712 (33.5%) of the articles, and males authored 1,414 (66.5%). There was no significant difference between years. More female authors wrote original research, and fewer wrote letters to the editor. Only Family Medicine had gender parity on its editorial board. Female authors wrote about a third of all original publications in family medicine journals between 2006-2009 even though they comprise 44% of the faculty. Further research can evaluate reasons for this gender disparity.

To analyze the inherent quality of articles published in our journal enjoying high citation rate, and to explore strategies on improving impact of papers. Scientific papers published in Chinese Journal of Burns from February 2000 to December 2009, with citation rate equal to or higher than 20 times were collected for classification according to their publication year, publication form, subject distribution, regional and institutional distribution, frequency of authors appeared in those published papers, frequency of winning prizes, and sources of fund (national, ministerial, or provincial). Data were processed by Microsoft Excel software. Altogether 64 scientific papers with high citation rate were published from 2000 to 2006. Original articles and expert forum accounted for 55 (86.0%). Twenty-one articles of clinical study were cited frequently, among them one was cited for 79 times. Articles dealing with subjects with popular interest or cutting-edge problems were cited frequently. Most articles winning high citation rate were originated from institutions located in Chongqing, Beijing, Shanghai, and Xi'an, etc. Those scientific papers which were instructed by specialists, with high level foundation and won prizes were cited with high frequency. The top 20 articles were mainly cited by excellent doctoral dissertations and master theses originated from 11 institutions for higher education, and source journals of Chinese Scientific and Technical Papers and Citations Database. Authors should emphasize subject planning in order to compose papers with high quality. The editorial board should make arrangements with influential specialists with related skills for their contributions based on subjects of popular interest concerning the cutting-edge problems of the specific specialty, and pay close attention to papers on clinical study and those with funding from high levels, to improve impact of the articles.

The purpose of the original STROBE was to provide guidance for authors, reviewers and editors to improve the comprehensiveness of reporting; however, STROBE has a unique focus on observational studies. Although much of the guidance provided by the original STROBE document is directly applicable, it was deemed useful to map those statements to veterinary concepts, provide veterinary examples and highlight unique aspects of reporting in veterinary observational studies. Here, we present the examples and explanations for the checklist items included in the STROBE-Vet Statement. Thus, this is a companion document to the STROBE-Vet Statement Methods and process document, which describes the checklist and how it was developed. © 2016 The Authors.

To determine the characteristics and trends of the original articles published in two major American radiology journals, AJR American Journal of Roentgenology (AJR) and Radiology, between 2001 and 2010. This was a retrospective bibliometric analysis that did not involve human subjects and was exempt from institutional review board approval. All 6542 original articles published in AJR and Radiology between 2001 and 2010 were evaluated. The following information was abstracted from each article: radiologic subspecialty, radiologic technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, affiliation of the first author, and country of the first author. In addition, all the variables examined were presented along with the trend over time. The most common subspecialty of study was abdominal (1219 of 6542, 18.6%), followed by vascular/interventional (804 of 6542, 12.3%). A total of 3744 (57.2%) original articles used magnetic resonance (MR) imaging or computed tomography (CT), 5495 (84.1%) were clinical research articles, 3060 (46.8%) had sample size of more than 50, 4087 (62.5%) were retrospective, 4714 (72.1%) performed statistical analysis, 6225 (95.2%) showed positive study outcome, 4784 (73.1%) were not funded, 3942 (60.3%) had four to seven authors, and 5731 (87.6%) were written by the primary author who was from a department of radiology or radiology-related specialties. The United States published 45.5% (2975 of 6542) of the articles, followed by Japan (n = 525, 8.0%), Germany (n = 485, 7.4%), and South Korea (n = 455, 7.0%). In the time trend analysis, the following variables showed a significantly positive trend: cardiac subspecialty, CT and MR imaging as the radiologic techniques, type of research as other (nonbasic, nonclinical), sample size of more than 50, four to seven as the number of authors, medicine-related department of the first author, and South Korea and Italy as countries of the first author. On the other hand, pediatric subspecialty, combined (basic and clinical) type of research, and number of authors fewer than four showed a significantly negative trend. The bibliometric analysis of the AJR and Radiology journals with articles published between 2001 and 2010 revealed characteristics and trends of the current radiology research that may provide useful information to researchers and editorial staff in radiology. © RSNA, 2012

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

The objective of this study was to analyze quantity, assess quality, and investigate international collaboration in research from Arab countries in the field of public, environmental and occupational health. Original scientific articles and reviews published from the 22 Arab countries in the category "public, environmental & occupational health" during the study period (1900 - 2012) were screened using the ISI Web of Science database. The total number of original and review research articles published in the category of "public, environmental & occupational health" from Arab countries was 4673. Main area of research was tropical medicine (1862; 39.85%). Egypt with 1200 documents (25.86%) ranked first in quantity and ranked first in quality of publications (h-index = 51). The study identified 2036 (43.57%) documents with international collaboration. Arab countries actively collaborated with authors in Western Europe (22.91%) and North America (21.04%). Most of the documents (79.9%) were published in public health related journals while 21% of the documents were published in journals pertaining to prevention medicine, environmental, occupational health and epidemiology. Research in public, environmental and occupational health in Arab countries is in the rise. Public health research was dominant while environmental and occupation health research was relatively low. International collaboration was a good tool for increasing research quantity and quality.

This study aimed to investigate the current status and policy of Conflict of interest (COI) reporting in biomedical journals in China. Thirty Chinese-language medical journals and 37 English-language biomedical journals indexed by Journal Citation Reports categories were included into this study. These 67 journals were all published in China. All articles published in the most recent two issues were checked for identifying the disclosure statement in the text or not. Twenty-one of 30 (70%) Chinese-language journals required a disclosure of author's potential COI. No journals require editors or referees to disclose the conflicts of interest to the readers. In total, 1,212 publications in Chinese-language were evaluated. Only two journals reported COI in their publications. For the 37 English-language journals, 32 (86.5%) required author's potential COI disclosure, and four of them required only research articles or original articles to disclose COI. A total of 1,170 publications were evaluated. Among them, 50% editorials, 79.3% review articles, and 73.6% original articles reported presence or absence of COI. In our studied journals, the percentage of the policies requiring author COI disclosure is still low. Biomedical journals published in China should enforce COI disclosure policies to authors, editors, and referees.

Background Qualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication. Design A quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research). Findings A 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, P<0.001). Additionally, a higher proportion of qualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research. Conclusions Despite an increase in the proportion of qualitative research in medical journals over a 10 year period, the proportion remains low. Journals' policies pertaining to qualitative research, as expressed by the appearance of specific guidelines and editorials/methodological papers on the subject, are independently associated with the publication of original qualitative research; irrespective of the journals' impact factor.

To identify 100 top-cited articles published in periodontal journals and analyse the research trends by using citation analysis. 100 top-cited articles published in periodontal journals were retrieved by searching the database of the ISI Web of Science and Journal Citation reports. For each article, the following principal bibliometric parameters: authorship, geographic and institute origin, manuscript type, study design, scope of study, and citation count of each time period were analysed from 1965 to 2015. The identified 100 top-cited articles were retrieved from five periodontal journals and citation counts were recorded between 262 and 1,693 times. For the institute of origin, the most productive institute, in terms of the number of 100 top-cited articles published, was the University of Gothenburg (Sweden) (n = 19), followed by the Forsyth Dental Center (USA) (n = 15). Most manuscripts were original research (n = 74), and the inflammatory periodontal disease (n = 59) was the most frequent topic studied. Interestingly, the trend of increase average citation reached significance for implantology (β = 26.75, P = 0.003) and systemic interactions (β = 29.83, P = 0.005), but not for inflammatory disease (β = -10.30, P = 0.248) and tissue regeneration (β = 9.04, P = 0.081). By using multivariable linear regression in a generalised linear model, suitable published journal (Journal of Clinical Periodontology), geographic regions (Europe), more intense international collaboration, adequate manuscript type (review article) and study design (systematic review) could be attributed to escalating average citation counts in implantology (all P < 0.05). However, for systemic interactions, only geographic region and study design were significantly associated with the increasing citation trend. These principal bibliometric characteristics revealed escalated trends in average citation count in implantology throughout time. Conflict-of-interest statement The authors have stated explicitly that there are no conflicts of interest in connection with this article. The study was self-funded by the authors and their institution.

Manterola, Carlos; Pineda, Viviana; Vial, Manuel; Losada, Héctor

2006-01-01

Objective: To determine the methodologic quality of therapy articles about humans published in ISI surgical journals, and to explore the association between methodologic quality, origin, and subject matter. Summary Background Data: It is supposed that ISI journals contain the best methodologic articles. Methods: This is a bibliometric study. All journals listed in the 2002 ISI under the subject heading of “Surgery” were included. A simple randomized sampling was conducted for selected journals (Annals of Surgery, The American Surgeon, Archives of Surgery, British Journal of Surgery, European Journal of Surgery, Journal of the American College of Surgeons, Surgery, and World Journal of Surgery). Published articles related to therapy on humans of the selected journals were reviewed and analyzed. All kinds of clinical designs were considered, excluding editorials, review articles, letters to the editor, and experimental studies. The variables considered were: place of origin, design, and the methodologic quality of articles, which was determined by applying a valid and reliable scale. The review was performed interchangeably and independently by 2 research teams. Descriptive and analytical statistics were used. Statistical significance was defined as P values less than 1%. Results: A total of 653 articles were studied. Studies came predominantly from the United States and Europe (43.6% and 36.8%, respectively). The subject areas most frequently found were digestive and hepatobiliopancreatic surgery (29.1% and 24.5%, respectively). Average and median methodologic quality scores of the entire series were 11.6 ± 4.9 points and 11 points, respectively. The association between methodologic quality and journals was determined. Also, the association between methodologic quality and origin was observed, but no association with subject area was verified. Conclusions: The methodologic quality of therapy articles published in the journals analyzed is low; however, statistical significance was determined between them. Association was observed between methodologic quality and origin, but not with subject matter. PMID:17060778

This paper reports on a qualitative exploration of the reasons for differences in pathways to care and duration of untreated psychosis (DUP) in the African, Caribbean and European (ACE) Pathways to Care study from the perspective of respondents to the study and their families. Ontario, Canada. Thirty-four participants in total. Twenty-five young people who had experienced a first episode of psychosis and nine family members. Participants were part of the ACE Pathways to Care study. We implemented six focus groups. Furthermore, we implemented four in-depth interviews with two African-origin young women, one Caribbean-origin woman, and one European-origin woman with lived experience of psychosis. Factors that influenced help-seeking delays across the three groups were: personal awareness of symptoms, family members' knowledge of psychotic symptoms and knowledge of mental health services. Youth and their family members described how stigma played a key role in pathways to care by stopping them from asking for help. The way in which stigma operated on the three groups' members, from feeling ashamed to feeling guilty for their mental illnesses, helped to explain differences in DUP between the groups. Guilt feelings emerged as a prominent theme among members from the African and Caribbean groups and it was not discussed in the European focus group. Delay in entering into first-episode psychosis programmes was also influenced by the stigma perceived by young people in healthcare settings. This had an impact on the therapeutic relationships, disclosure of symptoms and overall trust in the healthcare system. The findings of this paper suggest that stigma, especially internalised stigma, may operate in different ways in European-origin, African-origin and Caribbean-origin groups. These findings could inform the development of more equitable services for people in early stages of psychosis. Published by the BMJ Publishing Group Limited.

Publishing in scientific journals is an indicator of hospital quality and has become a standard of excellence for medical doctors and institutions. The aim of the study is to identify the scientific publications performed by Otolaryngology Departments in Spain within the period 2011-2015 and to compare them to a previous period between 1998-2002. Original papers published by Otolaryngology Departments in Spain in PubMed within 2011-2015 were retrieved. They were classified according to the type of journal published (international or Acta ORL Española) and the following subspecialty areas: Otology, Audiology and Neuro-Otology, Head and Neck Surgery (including Oncology), Rhinology and Paediatric ENT. Hospitals were ranked according to: number of original papers, accumulated impact factor and total number of publications. Between 2011 and 2015, 49342 publications were included in PubMed, 1.44% from Otolaryngology Departments in Spain. Between 1998 and 2002, 3.80% publications were from Spanish ENT departments. Of the 712 papers published within the period 2011-2015, 389 were published in Acta ORL Española and 323 in international journals. From the latter, 20.7% belong to the Otology area, 19.2% to Audiology-Neuro-otology, 30.6% to Head and Neck Surgery, 15.2% to Rhinology and 3.4% to Paediatric ENT. Five tertiary centres published at least 10 original papers in the same period. Spanish otolaryngology's contribution to international journals has decreased in the last 12 years. A few institutions are responsible for the majority of publications and they have notably increased the cumulative impact factor.

Quantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis. Articles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12.03.17. VOSviewer v.1.61 was used to construct bibliometric diagrams. A total of 549 original and review articles, published in 287 different peer-reviewed journals by 1888 authors, were identified. There was a steady increase in the number of published articles from 1995 to 2014. The majority of the articles was written in English (95.8%) and the United States was the leading country in the total number of published articles (n = 107, 19.5%) Journal of Alternative and Complementary Medicine published the greatest number of articles on the topic (n = 31, 5.6%). The article that received the greatest number of citations was published in Complementary Therapies in Medicine. Visualization analysis based on co-occurrences of words in the title and abstract revealed three clusters of research topics, including essential oil, intervention, and complementary medicine. This study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in aromatherapy research.

To identify historical trends in the field of pediatric psychology by examining the training origins of authors publishing in Journal of Pediatric Psychology since its formation in 1976. The researchers sampled four publication years (1976, 1986, 1996, and 2006) and recorded the authors of each published article. They obtained each author's doctoral training institution using information provided in the article, the American Psychological Association Membership Directory, or the ProQuest Dissertations and Theses Database and counted authorship totals for each institution in each year. Four institutions (Case Western Reserve University, University of Iowa, University of Kansas, and Purdue University) produced authorship entries in 3 of the 4 years sampled. The number of articles being published, the number of authors per article and the number of institutions consistently increased. The current study provided a historical perspective on graduate training and scholarly productivity in the field of pediatric psychology. Future research should investigate interesting trends revealed, such as how core groups of pediatric psychology scholars have contributed to the notable growth in institutions, specific programs within institutions, and authors published over the last 30 years.

Numerous vaccines are being actively developed for use in dermatologic diseases. Advances in the fields of immunotherapy, genetics and molecular medicine have allowed for the design of prophylactic and therapeutic vaccines with immense potential in managing infections and malignancies of the skin. This review addresses the different vaccines available for use in dermatological diseases and those under development for future potential use. The major limitation of our review is its complete reliance on published data. Our review is strictly limited to the availability of published research online through available databases. We do not cite any of the authors' previous publications nor have we conducted previous original research studies regarding vaccines in dermatology. Strength would have been added to our paper had we conducted original studies by our research team regarding the candidate vaccines delineated in the paper.

We validate the use of archiving Internet references by comparing the accessibility of published uniform resource locators (URLs) with corresponding archived URLs over time. We scanned the "Articles in Press" section in Annals of Emergency Medicine from March 2009 through June 2010 for Internet references in research articles. If an Internet reference produced the authors' expected content, the Web page was archived with WebCite (http://www.webcitation.org). Because the archived Web page does not change, we compared it with the original URL to determine whether the original Web page had changed. We attempted to access each original URL and archived Web site URL at 3-month intervals from the time of online publication during an 18-month study period. Once a URL no longer existed or failed to contain the original authors' expected content, it was excluded from further study. The number of original URLs and archived URLs that remained accessible over time was totaled and compared. A total of 121 articles were reviewed and 144 Internet references were found within 55 articles. Of the original URLs, 15% (21/144; 95% confidence interval [CI] 9% to 21%) were inaccessible at publication. During the 18-month observation period, there was no loss of archived URLs (apart from the 4% [5/123; 95% CI 2% to 9%] that could not be archived), whereas 35% (49/139) of the original URLs were lost (46% loss; 95% CI 33% to 61% by the Kaplan-Meier method; difference between curves P<.0001, log rank test).

2015-03-01

In recent decades, there has been an increase in the number of women practicing medicine. We believe this shift may be reaching academic publications in ophthalmology and changing gender trends. To determine whether there has been an increase in women publishing academic articles and editorials in ophthalmology during the past decade. In this observational retrospective study, 3 ophthalmology journals were sampled from 2000 and 2010 for at least 100 articles per journal, per year, and all editorials published in both years. Data reviewed included the authors' gender, number of authors, number of references, subspecialty, and country of origin. Publication by women authors. The primary outcome measure was an increase in women publishing in ophthalmology. The hypothesis was formulated before data collection. Our analysis included 671 original articles (336 from 2000 and 335 from 2010) and 89 editorials. The percentage of original articles with a woman as first author increased from 23.2% in 2000 to 32.5% in 2010, a difference of 9.3% (95% CI, 23.3%-32.5%; P = .005). The percentage of original articles with a woman last author increased from 16.4% in 2000 to 24.2% in 2010, a difference of 7.8% (95% CI, 16.4%-24.2%; P = .01). The percentage of original articles with a woman first author increased in Asia from 1.2% in 2000 to 8.4% in 2010, a difference of 7.2% (95% CI, 1.2%-8.4%; P < .001). The percentage of articles with a woman last author increased in Europe from 2.2% in 2000 to 7.5% in 2010, a difference of 5.3% (95% CI, 2.2%-7.5%; P < .001) and in Asia from 0% in 2000 to 6.0% in 2010, a difference of 6.0% (95% CI, 0%-6%; P < .001). Editorials were written predominantly by men: 33 of 38 editorials (87%) in 2000 and 46 of 51 (90%) in 2010, a difference of 3% (95% CI, 87%-90%; P = .62), showing a trend toward decreased editorial authorship by women during the past decade. Our data suggest an increase in women publishing original investigations in ophthalmic literature, but no increase in editorial authorship.

The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. To determine the characteristics of papers published in nutrition journals. Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Almost half the papers studied healthy people (53.3%). The most frequent illness was obesity (13.9%). Food consumption is the most frequent risk factor (63.3%). Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors.

Perform a bibliometric analysis of the orthodontic literature on skeletal Class II malocclusions during the first decade of the 21st century. A retrospective, observational, and comprehensive study ranging from January the first 2001 to December 31 2010, based on the articles published in four high impact factor orthodontic journals: Angle Orthod, OCR, EJO, and AJODO (Quotation Report Newspaper of the Scientific Information Institute). In the 4565 reviewed articles, only 338 were published on Class II malocclusions. Brazil, the United States, Turkey, and Germany are the nationalities, which have published the most. The cross-sectional descriptive studies represent 33%, randomized clinical trials (RCTs) 10.5%, meta-analyses 0.3%. Kanavakis et al. (2006) reported 72.34% of original articles, 2.83% of synthetic reviews, 8.89% of case reports, and 15.75% of unclassifiable articles. In conclusion, searchers in Orthodontics are invited to publish more clinical trials on skeletal Class II malocclusions. Copyright © 2018. Published by Elsevier Masson SAS.

Publication rates and determinants of publication were studied based on abstracts presented at pancreatic meetings. All abstracts presented at the 1994 and 1995 annual meetings of the European Pancreatic Club (EPC) and the American Pancreatic Association (APA) were followed up by searching MEDLINE. Publication rates were compared using log-rank tests and multiple logistic regression. The prestige of the publishing journals was compared using Kruskal-Wallis tests on scientific impact factors (SIF). Overall, 340 abstracts were presented at the EPC, and 254 were presented at the APA. Of these, 203 (59.7%, EPC) and 138 (54.3%, APA) were later published in peer-reviewed journals. Publication rates did not differ by study type or country region of origin. In addition, median SIFs were similar by conference (APA vs. EPC) and research type (basic science vs. clinical studies) (overall, 1.7). However, North American and North/West European articles were published in higher impact journals as compared with those from other countries. Publication rates and median journal SIFs in pancreas research are similar to those reported from other medical specialty meetings. There is no difference by conference, type of research, or origin (North American vs. European).

To describe and analyze the general characteristics and methodology of indexed publications by the health staff of the Mexican Social Security Institute in 1997. Original articles were evaluated. The primary sources included Index Medicus, Current Contents and the Mexican National Council of Science and Technology (CONACYT) index. The following information was gathered for each article: affiliation and chief activity of the first author; impact factor of the journal; research type; field of study; topic of study, and methodological conduction. This latter point included congruence between design and objective, reproducibility of methods, applicability of the analysis, and pertinence of the conclusions. A total of 300 original articles was published of which 212 (71%) were available for the present study: full-time investigators (FTI) generated 109 articles and investigators with clinical activities (CAI) wrote 103 articles. The median impact factor of the journals in which FTI published was 1.337 (0.341 to 37.297) and for CAI publications, 0.707 (0.400 to 4.237). Biomedical research predominated in the first group (41%) and clinical investigation in the second (66%). Statistically significant differences were identified for the methodological conduction between groups of investigators. Descriptive studies and publications in journals without impact factor predominated. The FTI group had the highest bibliographic production of original articles in indexed journals with an impact factor.

To study whether systematic reviewers apply procedures to counter-balance some common forms of research malpractice such as not publishing completed research, duplicate publications, or selective reporting of outcomes, and to see whether they identify and report misconduct. Cross-sectional analysis of systematic reviews and survey of their authors. 118 systematic reviews published in four journals (Ann Int Med, BMJ, JAMA, Lancet), and the Cochrane Library, in 2013. Number (%) of reviews that applied procedures to reduce the impact of: (1) publication bias (through searching of unpublished trials), (2) selective outcome reporting (by contacting the authors of the original studies), (3) duplicate publications, (4) sponsors' and (5) authors' conflicts of interest, on the conclusions of the review, and (6) looked for ethical approval of the studies. Number (%) of reviewers who suspected misconduct are reported. The procedures applied were compared across journals. 80 (68%) reviewers confirmed their data. 59 (50%) reviews applied three or more procedures; 11 (9%) applied none. Unpublished trials were searched in 79 (66%) reviews. Authors of original studies were contacted in 73 (62%). Duplicate publications were searched in 81 (69%). 27 reviews (23%) reported sponsors of the included studies; 6 (5%) analysed their impact on the conclusions of the review. Five reviews (4%) looked at conflicts of interest of study authors; none of them analysed their impact. Three reviews (2.5%) looked at ethical approval of the studies. Seven reviews (6%) suspected misconduct; only 2 (2%) reported it explicitly. Procedures applied differed across the journals. Only half of the systematic reviews applied three or more of the six procedures examined. Sponsors, conflicts of interest of authors and ethical approval remain overlooked. Research misconduct is sometimes identified, but rarely reported. Guidance on when, and how, to report suspected misconduct is needed. Published by the BMJ Publishing Group Limited.

To evaluate the benefit/risk profile of epoetin α biosimilar with the erythropoiesis-stimulating agents (ESAs) originators when administered to naïve patients from clinical practice. Population-based observational cohort study. All residents in the Lazio Region, Italy, with chronic kidney disease (CKD) or cancer retrieved from the Electronic Therapeutic Plan (ETP) Register for ESA between 2012 and 2014. Overall, 13 470 incident ESA users were available for the analysis, 8161 in the CKD and 5309 in the oncology setting, respectively. ESAs identified through the ATC B03XA were divided into 3 groups: (1) biosimilars; (2) epoetin α originator and (3) other originators. Patients were exposed to ESAs from the date of activation of the ETP, until the end of a 6-month follow-up period. Effectiveness (all-cause mortality and blood transfusion) and safety (major cardiovascular events, blood dyscrasia). A composite outcome including all-cause mortality, blood transfusion and major cardiovascular events was predefined. HRs of any outcome were estimated through Cox regression. We found no differences between patients on biosimilars or all originators with regard to the risk estimates of all-cause mortality, blood transfusion, major cardiovascular events and blood dyscrasia in the CKD setting. The composite outcome confirmed these results (biosimilars vs epoetin α originators: adjusted HR=1.02, 95% CI 0.78 to 1.33; biosimilars vs other originators: adjusted HR=1.09, 95% CI 0.85 to 1.41). Comparable risk estimates were observed between biosimilars and all originators in the oncology setting. In both settings, our findings are suggestive of no difference between biosimilars and originators on relevant effectiveness and safety outcomes. This study may contribute to settling future drug policy for the health services and provides reassurance on the approval pathway for biosimilars. The oncology setting merits further research, taking into account tumour types, tumour stage and anticancer chemotherapy administered. Published by the BMJ Publishing Group Limited.

[Report of Internal Consistency of the Scales in Research Published in the Colombian Journal of Psychiatry].

PubMed

Campo-Arias, Adalberto

2013-03-01

Establishment of the frequency of reporting internal consistency of the scales in research published in the Colombian Journal of Psychiatry (CJP) between 2006 and 2010. A descriptive study was carried out which computes the report of internal consistency (Cronbach alpha) of scales in research published as original papers in the CJP. Validation studies were excluded. A total of 114 articles were published and 30 of them were included in the analysis. Researchers applied 67 scales for measuring some variables and Cronbach alpha of 20 (29.8%) scales was reported in the participating population. In the CJP, few published studies that apply measuring scales for variables report internal consistency in the analyzed sample. It is necessary for authors to report the internal consistency of used scales in the study population to guarantee the validity of conclusions. Copyright © 2013 Asociación Colombiana de Psiquiatría.

An explosive epidemic occurred in Madeira Island (Portugal) from October 2012 to February 2013. Published data showed that dengue virus type 1 introduced from South America was the incriminated virus. We aim to determine the origin of the strain introduced to Madeira by travellers returning to Europe. Using phylogeographic analysis and complete envelope sequences we have demonstrated that the most probable origin of the strain is Venezuela. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Cookson, Michael S; Lowrance, William T; Murad, Mohammad H; Kibel, Adam S

2015-02-01

The purpose of this amendment is to incorporate relevant newly-published literature to better provide a rational basis for the management of patients with castration-resistant prostate cancer. The original systematic review and meta-analysis of the published literature yielded 303 articles published from 1996 through 2013. This review formed a majority of the guideline statements. Clinical Principles and Expert Opinions were used for guideline statements lacking sufficient evidence-based data. In April 2014, the CRPC guideline underwent amendment based on a second comprehensive literature search, which retrieved additional studies published between February 2013 and February 2014. Thirty-seven studies from this search provided data relevant to the specific treatment modalities for CRPC. Guideline statements based on six index patients developed to represent the most common scenarios encountered in clinical practice were amended appropriately. The additional literature provided the basis for an update of current supporting text as well as the incorporation of new guideline statements. Specifically, the addition of Radium-223 was placed in the guidelines related to the treatment of CRPC. Given the rapidly evolving nature of this field, this guideline should be used in conjunction with recent systematic literature reviews and an understanding of the individual patient's treatment goals. Patients' preferences and personal goals should be considered when choosing management strategies. The newly incorporated evidence-based statements supplement the original guideline published in 2013, which provided guidance for the treatment of men with CRPC. This guideline will be continually updated as new literature emerges in the field. Copyright © 2015 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

2016-01-01

The purpose of this study was to describe trends over time in female authorship in the radiology literature and to investigate the tendency of female first authors to publish with female senior authors. Data on the gender of academic physician authors based in the United States for all major articles published in three general radiology journals--Radiology, AJR, and Academic Radiology--were collected and analyzed for the years 1978, 1988, 1998, 2008, and 2013. Multivariate logistic regression was used to identify significant trends over time, and a chi-square test of independence was performed to determine significant relations between the genders of first and senior authors. The gender of 4182 of 4217 (99.17%) authors with MD degrees was determined. The proportion of original research articles published by women as first authors increased from 8.33% in 1978 to 32.35% in 2013 (p < 0.001). The proportion of original research articles with women as senior authors increased from 6.75% in 1978 to 21.90% in 2013 (p < 0.001). Female first and senior authorship increased significantly over time (first author, p < 0.001; senior author, p < 0.001). There was a statistically significant relation between the genders of first and senior authors of original research articles and guest editorials (p < 0.001). Over 35 years, there was a statistically significant upward linear trend of female physician participation in authorship of academic radiology literature. Female first authors were more likely to publish with female senior authors.

Thimerosal-containing vaccines and autistic spectrum disorder: a critical review of published original data.

PubMed

Parker, Sarah K; Schwartz, Benjamin; Todd, James; Pickering, Larry K

2004-09-01

The issue of thimerosal-containing vaccines as a possible cause of autistic spectrum disorders (ASD) and neurodevelopmental disorders (NDDs) has been a controversial topic since 1999. Although most practitioners are familiar with the controversy, many are not familiar with the type or quality of evidence in published articles that have addressed this issue. To assess the quality of evidence assessing a potential association between thimerosal-containing vaccines and autism and evaluate whether that evidence suggests accepting or rejecting the hypothesis, we systematically reviewed published articles that report original data pertinent to the potential association between thimerosal-containing vaccines and ASD/NDDs. Articles for analysis were identified in the National Library of Medicine's Medline database using a PubMed search of the English-language literature for articles published between 1966 and 2004, using keywords thimerosal, thiomersal, mercury, methylmercury, or ethylmercury alone and combined with keywords autistic disorder, autistic spectrum disorder, and neurodevelopment. In addition, we used the "related links" option in PubMed and reviewed the reference sections in the identified articles. All original articles that evaluated an association between thimerosal-containing vaccines and ASD/NDDs or pharmacokinetics of ethylmercury in vaccines were included. Twelve publications that met the selection criteria were identified by the literature search: 10 epidemiologic studies and 2 pharmacokinetic studies of ethylmercury. The design and quality of the studies showed significant variation. The preponderance of epidemiologic evidence does not support an association between thimerosal-containing vaccines and ASD. Epidemiologic studies that support an association are of poor quality and cannot be interpreted. Pharmacokinetic studies suggest that the half-life of ethylmercury is significantly shorter when compared with methylmercury. Studies do not demonstrate a link between thimerosal-containing vaccines and ASD, and the pharmacokinetics of ethylmercury make such an association less likely. Epidemiologic studies that support a link demonstrated significant design flaws that invalidate their conclusions. Evidence does not support a change in the standard of practice with regard to administration of thimerosal-containing vaccines in areas of the world where they are used.

A negative trend of biomedical research in Libya: a bibliometric study.

It is well established that Libya is lagging behind its peers in biomedical research. The aim of this study is to analyse all the original biomedical publications affiliated with Libya from 1973 to 2007. PubMed and the Science Citation Index Expanded were searched for 'original research' biomedical studies affiliated with Libya. The generated data were hand searched and 329 'original research' studies were included in the analysis. The first study was published in 1973. Publication rate peaked to an average of 15.2 studies per year during 1986-1996 and dropped to an average of 8.8 studies per year during 1997-2007. Of 166 first authors; 41% were Libyans and 59% were expatriates. The latter contributed 104 studies between 1986 and 1996 and 36 studies between 1997 and 2007, while the Libyans contributed 63 and 61 studies in the two respective periods. Authors affiliated with Benghazi produced 67% of the published studies, while authors from Tripoli produced 30% and other medical schools, hospitals and research centres from other Libyan cities produced only 3%. This study showed a decline in biomedical research publication in Libya. We propose that the lack of a research culture among the Libyan medical professionals is one of the factors contributing to this decline, which coincided with the departure of expatriate doctors from Libya. Raising awareness of the importance of research and improving research skills among Libyan medical professionals may help to reverse the current trend.

Although sporadic male predominance in hiccup patients has been reported, the association between gender differences and triggering factors has rarely been evaluated in patients with hiccups. The aim of this study was to investigate whether gender differences exist in hiccup patients by analyzing all previously published hiccup literature containing gender and etiology information. Published literature on this topic was identified using a standardized search strategy in the PubMed, SCOPUS, and CINAHL electronic databases. The literature search included studies published from January 1990 to December 2013. Searches were limited to English-language publications. Of 476 identified studies, 318 studies were eligible including eight case-control studies that contained nonhiccup control groups. Triggering factors for hiccups were categorized into two types: central nervous system (CNS) and non-CNS causes. Odds ratios (ORs) were calculated for the eight case-control studies and event rates for the other studies by meta-analysis. In addition, gender differences and mean ages were analyzed for the case studies. Pooled OR was 2.42 (95% confidence interval [CI] 1.40-4.17) with inclination for male predominance. Subgroup analysis by cause showed clear male predominance in the non-CNS type with OR of 11.72 (95% CI 3.16-43.50), whereas indistinct in the CNS type with OR of 1.74 (95% CI 0.95-3.16). Of the remaining 310 studies with 864 patients, previous findings were consistent. Male predominance was consistent in non-CNS (85.1%, 95% CI 78.2-90.2) and unknown origin (82.2%, 95% CI 75.8-87.2) patients, whereas mitigating the sex discrepancy in those with CNS origin (65.8%, 95% CI 53.1-76.5). We demonstrated male predominance in hiccup patients. This gender difference for hiccups was more pronounced in patients with non-CNS causes, whereas indistinct in patients with CNS causes.

DOORS to the semantic web and grid with a PORTAL for biomedical computing.

PubMed

Taswell, Carl

2008-03-01

The semantic web remains in the early stages of development. It has not yet achieved the goals envisioned by its founders as a pervasive web of distributed knowledge and intelligence. Success will be attained when a dynamic synergism can be created between people and a sufficient number of infrastructure systems and tools for the semantic web in analogy with those for the original web. The domain name system (DNS), web browsers, and the benefits of publishing web pages motivated many people to register domain names and publish web sites on the original web. An analogous resource label system, semantic search applications, and the benefits of collaborative semantic networks will motivate people to register resource labels and publish resource descriptions on the semantic web. The Domain Ontology Oriented Resource System (DOORS) and Problem Oriented Registry of Tags and Labels (PORTAL) are proposed as infrastructure systems for resource metadata within a paradigm that can serve as a bridge between the original web and the semantic web. The Internet Registry Information Service (IRIS) registers [corrected] domain names while DNS publishes domain addresses with mapping of names to addresses for the original web. Analogously, PORTAL registers resource labels and tags while DOORS publishes resource locations and descriptions with mapping of labels to locations for the semantic web. BioPORT is proposed as a prototype PORTAL registry specific for the problem domain of biomedical computing.

2015-06-01

In this study, we aimed to give insight into the article review process by investigating the characteristics and the fate of manuscripts submitted to the American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO). The following information was obtained for original articles submitted to the AJO-DO in 2008: (1) for rejected articles: the reasons for rejection and the journal of subsequent publication when applicable; (2) for accepted articles: the number of revisions and the time elapsed to publication; and (3) for all articles: study topic, study design, area of origin, and statistically significant findings. Findings were reported using descriptive statistics, the chi-square test for equality of proportions, and multiple regression where appropriate. Post-hoc pair-wise tests were checked against the Bonferroni correction to account for multiple testing. Of the 440 original articles submitted to AJO-DO in 2008, 116 (26%) were accepted and published an average of 21 months (SD, 5 months) after acceptance. Rejected articles totaled 324 (74%), with 137 (42%) finding subsequent publication an average of 22 months (SD, 11 months) after rejection by the AJO-DO. The top 3 reasons for rejection by the AJO-DO were (1) poor study design (59% of rejected articles), (2) outdated or unoriginal topic (42%), and (3) inappropriate for the AJO-DO's audience (27%). Manuscripts rejected for poor study design had the least success for subsequent publication, whereas those rejected as inappropriate for the AJO-DO had the highest rate of publication elsewhere. Area of origin was significantly associated with acceptance by the AJO-DO, with articles from United States and Canada most likely to be accepted (P < 0.01). Articles from countries with the lowest publication rate in the AJO-DO had the highest publication rate elsewhere. The presence of statistically significant findings was shown to be significantly associated with acceptance by the AJO-DO (P = 0.013) but not with publication elsewhere (P = 0.77). Rejection by the AJO-DO does not preclude publication elsewhere, although articles rejected for poor study design were least likely to be eventually published. Many publishable articles are rejected by the AJO-DO as inappropriate for its readership, and these were the most likely to find publication elsewhere. Articles with the highest chance of acceptance by the AJO-DO were those from the United States and Canada and those reporting statistically significant results.

Rodríguez-Lago, L; Molina-Leyva, A; Pereiro-Ferreirós, M; García-Doval, I

2018-06-01

For scientific journals, achieving a high impact factor (IF) has become a goal in its own right. Our aim was to describe the influence of article type on the IF of dermatology journals. We used the Scopus database to calculate an IF for Actas Dermo-Sifiliográficas and the major dermatology journals, excluding articles without abstracts, letters to the editor, and conference proceedings. Included articles were classified into 4 categories: case reports, original articles, narrative reviews, and other. We also calculated the mean IF for each article type. We then compared our results with IFs published by the Institute for Scientific Information. The proportion of each type of article differed between journals. Original articles carried the greatest weight in the major journals (BJD, 76.8%; Contact, 81.1%; JAAD, 63.4%; JAMA Dermatol, 63.7%.) but not in Actas Dermo-Sifiliográficas, where only 31.7% were original research articles. A higher IF was associated with the publication of reviews and original articles; a lower IF was associated with the publication of case reports and other article types. Publishing case reports, which have lower citation rates, leads to a lower IF. Publishing reviews and original articles will lead to a higher IF. Journals that seek a higher IF should probably publish more reviews and original articles and fewer case reports. Editorial boards should seek a balance between the interests of their clinician readers and the journal's need for a higher IF.

Bayesian evaluation of effect size after replicating an original study

PubMed Central

van Aert, Robbie C. M.; van Assen, Marcel A. L. M.

2017-01-01

The vast majority of published results in the literature is statistically significant, which raises concerns about their reliability. The Reproducibility Project Psychology (RPP) and Experimental Economics Replication Project (EE-RP) both replicated a large number of published studies in psychology and economics. The original study and replication were statistically significant in 36.1% in RPP and 68.8% in EE-RP suggesting many null effects among the replicated studies. However, evidence in favor of the null hypothesis cannot be examined with null hypothesis significance testing. We developed a Bayesian meta-analysis method called snapshot hybrid that is easy to use and understand and quantifies the amount of evidence in favor of a zero, small, medium and large effect. The method computes posterior model probabilities for a zero, small, medium, and large effect and adjusts for publication bias by taking into account that the original study is statistically significant. We first analytically approximate the methods performance, and demonstrate the necessity to control for the original study’s significance to enable the accumulation of evidence for a true zero effect. Then we applied the method to the data of RPP and EE-RP, showing that the underlying effect sizes of the included studies in EE-RP are generally larger than in RPP, but that the sample sizes of especially the included studies in RPP are often too small to draw definite conclusions about the true effect size. We also illustrate how snapshot hybrid can be used to determine the required sample size of the replication akin to power analysis in null hypothesis significance testing and present an easy to use web application (https://rvanaert.shinyapps.io/snapshot/) and R code for applying the method.

Research replication, or repeating a study de novo, is the scientific standard for building evidence and identifying spurious results. While replication is ideal, it is often expensive and time consuming. Reproducibility, or reanalysis of data to verify published findings, is one proposed minimum alternative standard. While a lack of research reproducibility has been identified as a serious and prevalent problem in biomedical research and a few other fields, little work has been done to examine the reproducibility of public health research. We examined reproducibility in 6 studies from the public health services and systems research subfield of public health research. Following the methods described in each of the 6 papers, we computed the descriptive and inferential statistics for each study. We compared our results with the original study results and examined the percentage differences in descriptive statistics and differences in effect size, significance, and precision of inferential statistics. All project work was completed in 2017. We found consistency between original and reproduced results for each paper in at least 1 of the 4 areas examined. However, we also found some inconsistency. We identified incorrect transcription of results and omitting detail about data management and analyses as the primary contributors to the inconsistencies. Increasing reproducibility, or reanalysis of data to verify published results, can improve the quality of science. Researchers, journals, employers, and funders can all play a role in improving the reproducibility of science through several strategies including publishing data and statistical code, using guidelines to write clear and complete methods sections, conducting reproducibility reviews, and incentivizing reproducible science.

New journal selection for quantitative survey of infectious disease research: application for Asian trend analysis

PubMed Central

2009-01-01

Background Quantitative survey of research articles, as an application of bibliometrics, is an effective tool for grasping overall trends in various medical research fields. This type of survey has been also applied to infectious disease research; however, previous studies were insufficient as they underestimated articles published in non-English or regional journals. Methods Using a combination of Scopus™ and PubMed, the databases of scientific literature, and English and non-English keywords directly linked to infectious disease control, we identified international and regional infectious disease journals. In order to ascertain whether the newly selected journals were appropriate to survey a wide range of research articles, we compared the number of original articles and reviews registered in the selected journals to those in the 'Infectious Disease Category' of the Science Citation Index Expanded™ (SCI Infectious Disease Category) during 1998-2006. Subsequently, we applied the newly selected journals to survey the number of original articles and reviews originating from 11 Asian countries during the same period. Results One hundred journals, written in English or 7 non-English languages, were newly selected as infectious disease journals. The journals published 14,156 original articles and reviews of Asian origin and 118,158 throughout the world, more than those registered in the SCI Infectious Disease Category (4,621 of Asian origin and 66,518 of the world in the category). In Asian trend analysis of the 100 journals, Japan had the highest percentage of original articles and reviews in the area, and no noticeable increase in articles was revealed during the study period. China, India and Taiwan had relatively large numbers and a high increase rate of original articles among Asian countries. When adjusting the publication of original articles according to the country population and the gross domestic product (GDP), Singapore and Taiwan were the most productive. Conclusion A survey of 100 selected journals is more sensitive than the SCI Infectious Disease Category from the viewpoint of avoiding underestimating the number of infectious disease research articles of Asian origin. The survey method is applicable to grasp global trends in disease research, although the method may require further development. PMID:19804650

2018-03-01

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

Mehta, Nikisha; Marshman, Zoe

2016-09-01

BackgroundThis systematic appraisal was conducted to determine if the Evidence-Based Dentistry Journal (EBDJ) acts as a reliable and contemporary source of knowledge for practitioners across all disciplines within dentistry.ObjectivesThe main objectives were to determine i) the year the articles were published and included in the EBDJ; ii) if the articles published covered all fields equally within dentistry; iii) the type of study design of the articles reported in the journal and; iv) the level of expertise of the writers of the commentaries.MethodsThis study used a systematic approach to assess the articles included in the journal. Data were extracted on the difference in the year the article was originally published and the year the article was included in the EBDJ, the number of articles in each dental discipline, the type of study designs included in the journal and the expertise of the commentators of each article. The information provided by the journal was validated by accessing the original articles through electronic databases.ResultsThe appraisal considered the 582 articles that met the inclusion criteria. Overall, 45.3% of the articles were included in the EBDJ in the same year and 44.8% of the articles were included a year after they were originally published. The number of articles varied across disciplines within dentistry: 23.7% from dental public health, 18.4% from periodontology and 11.8% from orthodontics, with only 4.6% from prosthodontics, 1% from oral pathology and 0.5% from dental materials. Most of the articles were systematic reviews and randomised controlled trials at 72% and 22.3% respectively. The writers of the commentaries were mostly academics and hospital consultants (71.2% and 13.6% commentators).ConclusionsOn the whole, it can be concluded that the journal acts as a reliable and contemporary source of knowledge/evidence for dentists, however, not all specialities within dentistry had equal coverage.

When characterizing a scientific journal from the bibliometric standpoint, it is of importance to know how many authors were involved in the studies published as well as the geographical areas where these authors are located and the type of institutions by which they are employed. The aim of this article is that of analyzing the geographical spread of these authors and the institutions by which they are employed, as well as its evolution as regards the original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period. Of the original articles published in the Revista Española de Salud Pública throughout the studied ten-year period, a calculation has been made as to the total number of authors, the number of occasional authors (authors having published solely one article), transitivity index, the ratio between the number of male and female authors, the productivity of the authors and their institutions and the spread of authors and the institutions by which they are employed by Autonomous Communities. Of the original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period, a total of 1,052 different authors were involved, 1,000 of whom were Spanish and 52 foreigners. The ratio of male authors to female authors for the period in question was 1.29. The Autonomous Communities from which the largest number of authors came were Community of Madrid (16.3%), Andalusia (13.4%) and the Community of Valencia (12.5%). The institutions by which the authors are employed are located most often in Community of Madrid (16.5%), in Community of Valencia (11.3%) and Andalusia and Catalonia (10.5%). A total of 37.6% of the authors work at centers devoted to health care, followed by authors who work at Universities (26.3%). On calculating the spread of the type of institution by Autonomous Communities, in the Community of Madrid and in the Community of Valencia and Andalusia, the most frequent institution is that of the primary care centers (50%, 43.3% and 28.6% respectively); and in Catalonia the specialized care centers (42.9%). The Revista Española de Salud Pública is a scientific journal well known in the whole spanish territory and in the Latinoamerican countries. The productivity of the authors publishing in this journal, the productivity of their institutions where they work and that of Autonomous Regions where they belong to, is similar to other magazines. The productivity of the authors is greater when we look at other public health magazines or other countries.

The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement was first published in 2007 and again in 2014. The purpose of the original STROBE was to provide guidance for authors, reviewers, and editors to improve the comprehensiveness of reporting; however, STROBE has a unique focus on observational studies. Although much of the guidance provided by the original STROBE document is directly applicable, it was deemed useful to map those statements to veterinary concepts, provide veterinary examples, and highlight unique aspects of reporting in veterinary observational studies. Here, we present the examples and explanations for the checklist items included in the STROBE-Vet statement. Thus, this is a companion document to the STROBE-Vet statement methods and process document (JVIM_14575 "Methods and Processes of Developing the Strengthening the Reporting of Observational Studies in Epidemiology-Veterinary (STROBE-Vet) Statement" undergoing proofing), which describes the checklist and how it was developed.

2018-06-01

The purpose of this study was to compare (1) major complication, (2) revision, and (3) conversion to arthroplasty rates following hip arthroscopy between database studies and original research peer-reviewed publications. A systematic review was performed using PRISMA guidelines. PubMed, SCOPUS, SportDiscus, and Cochrane Central Register of Controlled Trials were searched for studies that investigated major complication (dislocation, femoral neck fracture, avascular necrosis, fluid extravasation, septic arthritis, death), revision, and hip arthroplasty conversion rates following hip arthroscopy. Major complication, revision, and conversion to hip arthroplasty rates were compared between original research (single- or multicenter therapeutic studies) and database (insurance database using ICD-9/10 and/or current procedural terminology coding terminology) publishing studies. Two hundred seven studies (201 original research publications [15,780 subjects; 54% female] and 6 database studies [20,825 subjects; 60% female]) were analyzed (mean age, 38.2 ± 11.6 years old; mean follow-up, 2.7 ± 2.9 years). The database studies had a significantly higher age (40.6 + 2.8 vs 35.4 ± 11.6), body mass index (27.4 ± 5.6 vs 24.9 ± 3.1), percentage of females (60.1% vs 53.8%), and longer follow-up (3.1 ± 1.6 vs 2.7 ± 3.0) compared with original research (P < .0001 for all). Ninety-seven (0.6%) major complications occurred in the individual studies, and 95 (0.8%) major complications occurred in the database studies (P = .029; relative risk [RR], 1.3). There was a significantly higher rate of femoral neck fracture (0.24% vs 0.03%; P < .0001; RR, 8.0), and hip dislocation (0.17% vs 0.06%; P = .023; RR, 2.2) in the database studies. Reoperations occurred at a significantly higher rate in the database studies (11.1% vs 7.3%; P < .001; RR, 1.5). There was a significantly higher rate of conversion to arthroplasty in the database studies (8.0% vs 3.7%; P < .001; RR, 2.2). Database studies report significantly increased major complication, revision, and conversion to hip arthroplasty rates compared with original research investigations of hip arthroscopy outcomes.

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

How well does climate change and human health research match the demands of policymakers? A scoping review.

PubMed

Hosking, Jamie; Campbell-Lendrum, Diarmid

2012-08-01

In 2008, the World Health Organization (WHO) Member States passed a World Health Assembly resolution that identified the following five priority areas for research and pilot projects on climate change and human health: health vulnerability, health protection, health impacts of mitigation and adaptation policies, decision-support and other tools, and costs of health protection from climate change. To assess the extent to which recently published research corresponds to these priorities, we undertook a scoping review of original research on climate change and human health. Scoping reviews address topics that are too broad for a systematic review and commonly aim to identify research gaps in existing literature. We also assessed recent publication trends for climate change and health research. We searched for original quantitative research published from 2008 onward. We included disease burden studies that were specific to climate change and health and included intervention studies that focused on climate change and measured health outcomes. We used MEDLINE, Embase, and Web of Science databases and extracted data on research priority areas, geographic regions, health fields, and equity (systematic differences between advantaged and disadvantaged social groups). We identified 40 eligible studies. Compared with other health topics, the number of climate change publications has grown rapidly, with a larger proportion of reviews or editorials. Recent original research addressed four of the five priority areas identified by the WHO Member States, but we found no eligible studies of health adaptation interventions, and most of the studies focused on high-income countries. Climate change and health is a rapidly growing area of research, but quantitative studies remain rare. Among recently published studies, we found gaps in adaptation research and a deficit of studies in most developing regions. Funders and researchers should monitor and respond to research gaps to help ensure that the needs of policymakers are met.

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.

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

Evolving Trends in Endodontic Research: An Assessment of Published Articles in 2 Leading Endodontic Journals.

2015-12-01

The aim of this study was to evaluate and analyze the evolving trends in endodontic research in 2 leading endodontic journals (ie, Journal of Endodontics and International Endodontic Journal) in articles published from January 2009 to December 2013. The differences in content between this period and a 10-year earlier period from January 1999 to December 2003 were also evaluated. Each journal's content was accessed through the web edition. For each article, the following parameters were recorded: number of authors, article type, number of affiliations, field of study, source of article, and geographic origin. The recorded data were analyzed using both descriptive and analytic statistics. During 2009-2013 (second period), the mean number of authors per article increased significantly compared with 1999-2003 (first period). The main volume of the literature in both periods and journals was original research articles. The number of published reviews increased significantly from the first to the second study period in contrast to case reports/clinical articles, which presented a significant decrease. "Endodontic materials" was the most prevalent thematic category in both study periods. The number of published articles related to "biology" and "chemical preparation and disinfection" increased significantly from the first to the second study period. On the contrary, the number of articles regarding "obturation and microleakage" presented a considerable decrease at the same time. The United States was the leading country in the number of publications in the first period followed by Brazil. In the second period, this rank was reversed with Brazil becoming the leading country followed by the United States. In the last 15 years, the progress of the specialty of endodontology was apparent as shown through the trends and shifts in research orientation in published articles in the 2 leading endodontic journals. The results of the present reviewing process encourage both journals to publish well-designed research projects with a high degree of difficulty, thus contributing to a more evidence-based approach of endodontology.

2014-02-01

To identify the unique anatomical characteristic of the extensor carpi radialis brevis (ECRB) origin and points of differentiation from other extensors and to clarify the specific relationship of the ECRB to the underlying structures. We studied the origin of each extensor macroscopically for its muscular and tendinous parts; to identify the relationship between the ECRB origin and the deeper structures, we also examined the attachment of the joint capsule under the ECRB origin. The ECRB simply originated as a tendon without any muscle, whereas other extensors originated as a mixture of tendon and muscle. At the anterior part of the ECRB origin, the thin attachment of the joint capsule (average width, 3.3 mm) lay deep to the ECRB and was distinct. However, at the posterodistal portion, the joint capsule, annular ligament, and supinator were intermingled and originated as a single wide sheet from the humerus (average width, 10.7 mm). The anterior part of the ECRB origin was delicate, because the ECRB origin was purely tendinous, and the attachment of the articular capsule was thin compared with that of the posterodistal attachment. This thin attachment could be an initial factor leading to the development of lateral epicondylitis. The results of the current study may enhance magnetic resonance imaging understanding and may help clarify the etiology of the lateral epicondylitis.

The purpose of this study is to identify the top 100-cited articles dedicated to epilepsy and status epilepticus published in journals from January, 1950 through February, 2016 that have made key contributions in the field. We performed a search of journals and selected the top 100-cited articles on epilepsy and status epilepticus, respectively, by utilizing the Institute for Scientific Information database available under the banner of the Web of Science. The top-cited articles on epilepsy and status epilepticus were all published in 24 journals, respectively. In both fields of epilepsy and status epilepticus, the most frequently cited journal was Epilepsia (26 articles on epilepsy and 19 articles on status epilepticus). The 100 most-cited articles in the field of both epilepsy and status epilepticus mainly originated from institutions in the United States of America. The articles on epilepsy included 25 laboratory studies, 15 pharmacotherapy studies, 13 general review studies, 12 surgery studies, 11 neuroimaging studies, eight epidemiology studies, eight neuropsychiatry studies, six genetic studies, and two electrophysiology studies, whereas 41 laboratory studies, 21 epidemiology studies, 16 pharmacotherapy studies, nine electrophysiology studies, nine general review studies, and four neuroimaging studies were included in the field of status epilepticus. We demonstrate that neuroimaging, genetics, and surgery are emerging topics in the field of epilepsy over the past decades. Moreover, we found that the majority of top-cited articles on epilepsy and status epilepticus originated from institutions in the United States of America and most were published in Epilepsia.

Retracted Publications Within Radiology Journals.

PubMed

Rosenkrantz, Andrew B

2016-02-01

The purpose of this study was to characterize trends related to retracted publications within radiology journals. PubMed was queried to identify all articles with the publication type "retracted publication" or "notification of retraction." Articles published within radiology journals were identified using Journal Citation Reports' journal categories. Available versions of original articles and publication notices were accessed from journal websites. Citations to retracted publications were identified using Web of Science. Overall trends were assessed. Forty-eight retracted original research articles were identified within radiology journals since 1983, which included 1.1% of all PubMed "retracted publication" entries. Distinct PubMed entries were available for the retracted publication and retraction notification in 39 of 48 articles. The original PDF was available for 37 articles, although the articles were not watermarked as retracted in 23 cases. In six cases with a watermarked PDF, further searches identified nonwatermarked versions. Original HTML versions were available for 13 articles but 11 were not watermarked. The mean (± SD) delay between publication and retraction was 2.7 ± 2.8 years (range, 0-16 years). The mean number of citations to retracted articles was 10.9 ± 17.1 (range, 0-94 citations). Reasons for retraction included problematic or incorrect methods or results (although it typically was unclear whether these represented honest errors or misconduct) in 33.3% of cases, complete or partial duplicate publication in 33.3% of cases, plagiarism in 14.6% of cases, a permission issue in 8.3% of cases, the publisher's error in 6.3% of cases, and no identified reason in 6.3% of cases. One or no retractions occurred annually from 1986 to 2001, although two or more retractions occurred annually in nine of the 12 years from 2002 through 2013. Retraction represents an uncommon, yet potentially increasing, issue within radiology journals that publishers have inconsistently and insufficiently addressed. Greater awareness and training in proper biomedical research conduct, as well as establishment and enforcement of standardized publishers' policies, are warranted.

Reducing nutrition-related health problems in Arab countries requires an understanding of the performance of Arab countries in the field of nutrition and dietetics research. Assessment of research activity from a particular country or region could be achieved through bibliometric analysis. This study was carried out to investigate research activity in "nutrition and dietetics" in Arab countries. Original and review articles published from Arab countries in "nutrition and dietetics" Web of Science category up until 2012 were retrieved and analyzed using the ISI Web of Science database. The total number of documents published in "nutrition and dietetics" category from Arab countries was 2062. This constitutes 1% of worldwide research activity in the field. Annual research productivity showed a significant increase after 2005. Approximately 60% of published documents originated from three Arab countries, particularly Egypt, Kingdom of Saudi Arabia, and Tunisia. However, Kuwait has the highest research productivity per million inhabitants. Main research areas of published documents were in "Food Science/Technology" and "Chemistry" which constituted 75% of published documents compared with 25% for worldwide documents in nutrition and dietetics. A total of 329 (15.96%) nutrition - related diabetes or obesity or cancer documents were published from Arab countries compared with 21% for worldwide published documents. Interest in nutrition and dietetics research is relatively recent in Arab countries. Focus of nutrition research is mainly toward food technology and chemistry with lesser activity toward nutrition-related health research. International cooperation in nutrition research will definitely help Arab researchers in implementing nutrition research that will lead to better national policies regarding nutrition.

World gynecologic oncology publications and the Turkish contribution to the literature between 2000 and 2007.

To investigate the number of publications and the contribution from top-ranking countries, institutions, and authors in 3 gynecologic oncology journals (Gynecologic Oncology [GO], International Journal of Gynecological Cancer [IJGC], and European Journal of Gynaecological Oncology [EJGO]),as well as the degree of Turkish contribution between 2000 and 2007. Articles published between 2000 and 2007 in 3 gynecologic oncology journals indexed by the Science Citation Index were accessed via the ISI-Thomson website. Additionally, PubMed, Sciencedirect, and Blackwell-Synergy databases were used to identify the originating countries and institutions of the published articles. The types of articles, originating countries, and names of the institutions and authors were determined. Furthermore, the number of articles affiliated with Turkish institutions and the publication year were also determined. We located 6,851 articles published in the 3 journals. During this period 36.1%, 7.7%, 7.2%, 5.8% and 4.8% of the papers originated from the USA, Japan, Italy, Turkey, and England, respectively. The 5 most productive institutions were the University of Texas, Memorial Sloan-Kettering Cancer Center, Roswell Park Cancer Institute, University of Alabama, and University of Athens. The 5 most productive authors were Markman (USA), Chi (USA), Ayhan (Turkey), Barakat (USA), and Vergote (Belgium), respectively. In all, 36.1% of the papers originated from the USA, while 44% originated from 17 European countries. The USA was the first-ranked country of origin in GO and IJGC, while Turkey was the first-ranked country of origin in EJGO. Overall, 399 (5.8%) papers originated from Turkish institutions. Most of the gynecologic oncology publications originated from the USA and Western European countries, where gynecologic oncology training is available and surgical and research traditions are well established. On the other hand, Turkish researchers made an important contribution to gynecologic oncology research during the selected period of time; publications originating from Turkey exceeded in number all European countries, except those originating from Italy.

2004-01-01

Background We conducted this analysis to determine i) which journals publish high-quality, clinically relevant studies in internal medicine, general/family practice, general practice nursing, and mental health; and ii) the proportion of clinically relevant articles in each journal. Methods We performed an analytic survey of a hand search of 170 general medicine, general healthcare, and specialty journals for 2000. Research staff assessed individual articles by using explicit criteria for scientific merit for healthcare application. Practitioners assessed the clinical importance of these articles. Outcome measures were the number of high-quality, clinically relevant studies published in the 170 journal titles and how many of these were published in each of four discipline-specific, secondary "evidence-based" journals (ACP Journal Club for internal medicine and its subspecialties; Evidence-Based Medicine for general/family practice; Evidence-Based Nursing for general practice nursing; and Evidence-Based Mental Health for all aspects of mental health). Original studies and review articles were classified for purpose: therapy and prevention, screening and diagnosis, prognosis, etiology and harm, economics and cost, clinical prediction guides, and qualitative studies. Results We evaluated 60,352 articles from 170 journal titles. The pass criteria of high-quality methods and clinically relevant material were met by 3059 original articles and 1073 review articles. For ACP Journal Club (internal medicine), four titles supplied 56.5% of the articles and 27 titles supplied the other 43.5%. For Evidence-Based Medicine (general/family practice), five titles supplied 50.7% of the articles and 40 titles supplied the remaining 49.3%. For Evidence-Based Nursing (general practice nursing), seven titles supplied 51.0% of the articles and 34 additional titles supplied 49.0%. For Evidence-Based Mental Health (mental health), nine titles supplied 53.2% of the articles and 34 additional titles supplied 46.8%. For the disciplines of internal medicine, general/family practice, and mental health (but not general practice nursing), the number of clinically important articles was correlated withScience Citation Index (SCI) Impact Factors. Conclusions Although many clinical journals publish high-quality, clinically relevant and important original studies and systematic reviews, the articles for each discipline studied were concentrated in a small subset of journals. This subset varied according to healthcare discipline; however, many of the important articles for all disciplines in this study were published in broad-based healthcare journals rather than subspecialty or discipline-specific journals.

This study was undertaken to investigate the trends of orthopedic publications during the last decade, and to document the country of origin, journal, funding source, and language of contribution using PubMed. Orthopedic articles published between 2000 and 2009 were retrieved from PubMed using the following search terms: "orthopaedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])" and "orthopedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])." The articles were downloaded in XML file format, which contained the following information: article title, author names, journal names, publication dates, article types, languages, authors' affiliations and funding sources. These information was extracted, sorted, and rearranged using the database's management software. We investigated the annual number of published orthopedic articles worldwide and the annual rate of increase. Furthermore, the country of publication origin, journal, funding source, and language of contribution were also investigated. A total of 46,322 orthopedic articles were published and registered in PubMed in the last 10 years. The worldwide number of published orthopedic articles increased from 2,889 in 2000 to 6,909 in 2009, showing an annual increase of 384.6 articles, or an annualized compound rate of 10.2%. The United States ranked highest in the number of published orthopedic articles, followed by Japan, the United Kingdom, Germany, and the Republic of Korea. Among the orthopedic articles published worldwide during the last 10 years, 37.9% pertained studies performed in the United States. Fifty-seven point three percent (57.3%) of articles were published in journals established in the United States. Among the published orthopaedic articles, 4,747 articles (10.2%) disclosed financial support by research funds, of which 4,688 (98.8%) articles utilized research funds from the United States. Most articles were published in English (97.2%, 45,030 articles). The number of published orthopedic articles has been increasing over the last decade. The number of orthopedic articles, journals publication, and funding sources were dominated by research conducted in the United States, while share and growth of Asian countries including Japan, the Republic of Korea, and China were notable.

Federico Cesi and his field studies on the origin of fossils between 1610 and 1630.

PubMed

Scott, A C

2001-09-01

In 1603 Federico Cesi, along with four of his friends, founded the first Scientific Academy in Europe, the Accademia dei Lincei, which included Galileo Galillei as a member. Between 1611 and 1630 Cesi undertook an ambitious project to collect and record fossils from his lands around Acquasparta in Umbria. He had drawings and descriptions made of all the excavated fossils, fossil woods and their sites of origin. He died before his work could be published and it was left to his friend Francesco Stelluti to publish a monograph in which he claimed that evidence demonstrated that the fossil woods were formed from stone and were 'not once living'. The corpus of drawings, now in the Royal Collection at Windsor, has allowed the project to be reconstructed and fieldwork in Italy has shown that the complex nature of the fossil preservation could have easily confused the researchers and have led to misinterpretation of the fossils. This research by Cesi is the first to combine field and specimen data to interpret the origin of fossils and has been widely neglected by historians of Science.

Nuclear forensic publications, performance tests, and research and development efforts typically target the bulk global inventory of intentionally safeguarded materials, such as plutonium (Pu) and uranium (U). Other materials, such as neptunium (Np), pose a nuclear security risk as well. Trafficking leading to recovery of an interdicted Np sample is a realistic concern especially for materials originating in countries that reprocesses fuel. Using complementary forensic methods, potential signatures for an unknown Np oxide sample were investigated. Measurement results were assessed against published Np processes to present hypotheses as to the original intended use, method of production, and origin for this Np oxide. Published by Elsevier B.V.

Laparoscopic liver resection for malignancy: A review of the literature

PubMed Central

Alkhalili, Eyas; Berber, Eren

2014-01-01

AIM: To review the published literature about laparoscopic liver resection for malignancy. METHODS: A PubMed search was performed for original published studies until June 2013 and original series containing at least 30 patients were reviewed. RESULTS: All forms of hepatic resections have been described ranging from simple wedge resections to extended right or left hepatectomies. The usual approach is pure laparoscopic, but hand-assisted, as well as robotic approaches have been described. Most studies showed comparable results to open resection in terms of operative blood loss, postoperative morbidity and mortality. Many of them showed decreased postoperative pain, shorter hospital stays, and even lower costs. Oncological results including resection margin status and long-term survival were not inferior to open resection. CONCLUSION: In the hands of experienced surgeons, laparoscopic liver resection for malignant lesions is safe and offers some short-term advantages over open resection. Oncologically, similar survival rates have been observed in patients treated with the laparoscopic approach when compared to their open resection counterparts. PMID:25309091

Almost 40 years investigating near-death experiences: an overview of mainstream scientific journals.

PubMed

Sleutjes, Adriana; Moreira-Almeida, Alexander; Greyson, Bruce

2014-11-01

This article reviews mainstream scientific publications on near-death experiences (NDEs). We searched near-death experience in titles, key words, and abstracts at the Web of Knowledge database published between 1945 and 2013. We identified 266 relevant documents, the oldest from 1977. There was a strong predominance of opinion articles (book reviews, commentaries, and editorials), review articles, phenomenological description articles, and articles that originated in the United States. Since 2000, the number of longitudinal and cross-sectional studies has increased; there has been a diversification in the countries that have published on the subject and more articles that discuss the implications of NDEs for the mind-brain relationship. The results indicate that most scholarly publications on NDEs are recent, usually have no original empirical data, and are concentrated in North America and Western Europe. Future studies should focus on increasing the cultural diversity in the field and on testing explanatory hypotheses based on high-quality empirical data.

New psychoactive substances: an overview on recent publications on their toxicodynamics and toxicokinetics.

Meyer, Markus R

2016-10-01

This review article covers English-written and PubMed-listed review articles and original studies published between January 2015 and April 2016 dealing with the toxicodynamics and toxicokinetics of new psychoactive substances. Compounds covered include stimulants and entactogens, synthetic cannabinoids, tryptamines, NBOMes, phencyclidine-like drugs, benzodiazepines, and opioids. First, an overview and discussion is provided on timely review articles followed by an overview and discussion on recent original studies. Both sections are then concluded by an opinion on these latest developments. This review shows that the NPS market is still highly dynamic and that the data published on their toxicodynamics and toxicokinetics can hardly keep pace with the appearance of new entities. However, data available are very helpful to understand and predict how NPS may behave in severe intoxication. The currently best-documented parameter is the in vitro metabolism of NPS, a prerequisite to allow detection of NPS in biological matrices in cases of acute intoxications or chronic consumption. However, additional data such as their chronic toxicity are still lacking.

Authorship, collaboration, and predictors of extramural funding in the emergency medicine literature.

2008-01-01

The objectives of the study were to examine the last decade of general emergency medicine (EM) literature published in the United States for trends with regard to authorship and multidisciplinary collaboration and to estimate the effect on extramural funding. Print articles published in the Academic Emergency Medicine, Annals of Emergency Medicine, Journal of Emergency Medicine, and American Journal of Emergency Medicine between 1994 and 2003 were reviewed. Original research, case reports/series, and others (consensus/educational) were considered; abstracts, book reviews, and editorials were not. The author byline was reviewed for number, specialty, nationality, collaboration, and presence of extramural funding. Multidisciplinary collaboration was defined as authors from 2 or more specialties, whereas multi-institutional collaboration was defined as EM authors from more than one institution. Logistic regression was used to identify predictors of extramural funding from the variables collected. Of 5728 articles identified, there were 3278 (57%) original research, 1437 (25%) case reports/series, and 975 (17%) classified as others. The percentage funded was 22% for all articles (32% for original research). The literature had at least one EM investigator as coauthor 84% of the time. Article location of origin was the United States (63%), foreign (15%), and combined (22%). Multidisciplinary collaboration increased overall from 33% in 1994 to a high of 43% in 2003. Multi-institutional collaboration also increased from 16% in 1994 to 26% in 2003. The percentage of articles having 6 or more authors increased from 12% to 18% over the decade. Of all variables studied, only article type (original research: odds ratio, 4.8; 95% confidence interval, 4.0-5.6) and foreign source (non-United States: odds ratio, 1.3; 95% confidence interval, 1.1-1.5) predicted extramural funding. The number of authors per article in the EM literature has steadily increased over the last decade, as has evidence of collaboration with other specialties. This increase in collaboration and author number has not been associated with increased extramural funding in the general EM literature published in the United States.

This study considered genetic research relating to cancer outcomes and behaviors, specifically investigating the extent to which claims made in press releases ( N =23) and mainstream print media ( N =71) were fairly derived from their original presentation in scholarly journals ( N= 20 ). Central claims expressing gene-outcome relationships were evaluated by a large pool ( N= 40) of genetics graduate students. Raters judged press release claims as significantly more representative of material within the original science journal article compared with news article claims. Claims originating in news articles which demonstrated contact with individuals not directly involved in the research were judged by experts to be more representative of the original science as compared with those that demonstrated contact with individuals directly involved in the research.

On slaves and genes: "origins" and "processes" in genetic studies of the Brazilian population.

PubMed

Calvo-González, Elena

2014-01-01

In this article I examine how contemporary geneticists investigating the history and configuration of the Brazilian population engage with other academic disciplines. To do so I use as a case study some articles published by geneticists researching the presence of hemoglobin S variants in Brazil, in which there is a clear pretension to contribute to the analysis of issues such as slavery or Brazil's ethnic identity. By contrasting these studies with contemporary works from history and the social science, the explanatory centrality of "origin" in the genetic studies analyzed is problematized, as is the lack of interaction with the epistemological characteristics of other areas of knowledge.

To recognize the characteristics and path taken by the through analysis of the scientific production it has published over the period from 1967 to 2005. Scientometric methods were used to analyze reference data on the articles published in the Revista, retrieved from the databases ISI/Thomson Scientific (Web of Science), National Library of Medicine (PubMed) and Scientific Electronic Library Online (SciELO). The Revista is the only Brazilian publication in the field of public health that is indexed by ISI/Thomson Scientific. It is prominent as a medium for publishing Brazilian scientific production in public health and is displaying a geometric increase in publication and citation, with annual rates of 4.4% and 12.7%, respectively. The mean number of authors per paper has risen from 2 to 3.5 over recent years. Although original research articles predominate, the numbers of reviews, multicenter studies, clinical trials and validation studies have been increasing. The number of articles published in foreign languages has also increased, accounting for 13% of the total, and the leading countries originating these are the UK, USA, Argentina and Mexico. The number and diversity of journals citing the Journal has been increasing, many of which are non-Brazilian. Authorship per author shows good fit to Lotka's Law, but the parameters suggest greater concentration and less dispersion than would be expected. Among the fields of interest of published papers, the following topics account for more than 50% of the total volume: infectious-parasitic diseases and vectors; health promotion, policies and administration; and epidemiology, surveillance and disease control. The Revista shows great dynamism, without signs of abating or reaching a plateau any time soon. There are signs of progressively increasing complexity in the studies published, and more multidisciplinary work. The Revista seems to be widening its outreach and recognition, while remaining faithful to the field of public health in Brazil.

Here, we report a quantitative genome-wide analysis of DNA replication kinetics in several human cell types that contradicts this view. DNA combing in HeLa cells sorted into four temporal compartments of S phase shows that replication origins are spaced at 40 kb intervals and fire as small clusters whose synchrony increases during S phase and that replication fork velocity (mean 0.7 kb/min, maximum 2.0 kb/min) remains constant and narrowly distributed through S phase. However, multi-scale analysis of a genome-wide replication timing profile shows a broad distribution of replication timing gradients with practically no regions larger than 100 kb replicating at less than 2 kb/min. Therefore, HeLa cells lack large regions of unidirectional fork progression. Temporal transition regions are replicated by sequential activation of origins at a rate that increases during S phase and replication timing gradients are set by the delay and the spacing between successive origin firings rather than by the velocity of single forks. Activation of internal origins in a specific temporal transition region is directly demonstrated by DNA combing of the IGH locus in HeLa cells. Analysis of published origin maps in HeLa cells and published replication timing and DNA combing data in several other cell types corroborate these findings, with the interesting exception of embryonic stem cells where regions of unidirectional fork progression seem more abundant. These results can be explained if origins fire independently of each other but under the control of long-range chromatin structure, or if replication forks progressing from early origins stimulate initiation in nearby unreplicated DNA. These findings shed a new light on the replication timing program of mammalian genomes and provide a general model for their replication kinetics. PMID:22219720

Bibliometric analysis of scientific performance within a country or speciality, facilitate the recognition of factors that may further enhance research activity and performance. Our aim was to illicit the current state of Irelands orthopaedic research output in terms of quantity and quality. We performed a retrospective bibliometric analysis of all Irish orthopaedic publications over the past 5 years, in the top 20 peer-reviewed orthopaedic journals. Utilising the MEDLINE database, each journal was evaluated for articles that were published over the study period. Reviews, editorials, reports and letters were excluded. Each article abstract was analysed for research content, and country of origin. A nation's mean IF was defined by multiplying each journal's IF by the number of articles. Publications per million (PmP) was calculated by dividing the total number of publications by the population of each country. We analysed a total of 25,595 article abstracts. Ireland contributed 109 articles in total (0.42% of all articles), however ranking according to population per million was 10th worldwide. Ireland ranked 18th worldwide in relation to mean impact factor, which was 2.91 over the study period. Ireland published in 16 of the top 20 journals, 9 of these were of European origin, and 1 of the top 5 was of American origin. In total, 61 Irish articles were assignable to clinical orthopaedic units. Clinical based studies (randomised controlled trials, observational, and epidemiology/bibliometric articles) and research based studies (In vivo, In vitro, and biomechanical) numbered 76 (69.7%) and 33 (30.2%) articles, respectively. This study provides a novel overview of current Irish orthopaedic related research, and how our standards translate to the worldwide orthopaedic community. In order to maintain our publication productivity, academic research should continue to be encouraged at post graduate level.

The lenticular process of the incus.

PubMed

Graboyes, Evan M; Hullar, Timothy E; Chole, Richard A

2011-12-01

Seventeenth century anatomists, including Franciscus Sylvius, identified a small bony structure between the distal end of the incus and the stapes that they believed was a separate and thus additional ossicle. The existence of the ossicle at the distal end of the long process of the incus was controversial for the next 200 years. In the 19 th century, anatomists including Johann Friedrich Blumenbach, Samuel Thomas Soemmerring, Henry Jones Shrapnell, Eduard Hagenbach, and Joseph Hyrtl provided numerous arguments to demonstrate why the so-called additional ossicle was actually attached to the incus by a thin strut, and thus not a separate bone. The objective of this study was to review the history of the discovery and description of the lenticular process of the incus. Data sources included original published manuscripts and monographs obtained from the historical collections at Washington University in St. Louis and photographs of original materials from cooperating libraries. A detailed study of the published evidence revealed that the lenticular process of the incus was originally thought to be a separate, or fourth, ossicle. Later studies revealed that the lenticular "ossicle" was actually attached to the incus by a thin strut. The ovoid end of the incus should be referred to as the "lenticular process" of the incus, attached to the long process by a thin strut or pedicle. The best nomenclature for the bony connection between the lenticular process and the long process of the incus remains uncertain.

Knowles, Judie M; Gray, Morag A

2011-11-01

This paper commences with affirmation of the importance of research critique within academic programmes of study, and the context of this skill within the nursing profession. Judie (student) shares an experience from a Professional Doctorate in Education (EdD) assignment that involved selecting and critiquing a piece of published research. "The qualities of an effective mentor" (Gray and Smith, 2000) was critiqued using the Critical Appraisal Skills Programme (CASP, 2006) framework. Morag was the researcher and co-author (Gray and Smith, 2000) and was subsequently contacted by Judie for the purposes of validating her critique assignment. On the tenth anniversary since publication of her PhD research findings Morag reflects on the original article in the light of Judie's critique and shares evaluative comments. Some of the assignment critique is validated by Morag, whilst some of the evaluation demonstrates unreliability of critique shown by Judie. Discussion surrounding sufficiency of research critique through systematic examination of a published article, versus an original research report such as a thesis ensues. The student and researcher/author reveal their learning from this collaborative experience and conclude with recommendations for; setting critique assignments; authors publishing their research findings; and students undertaking critique assignments.

A wide variety of probiotic products has been introduced into the market in the past decade. Research trends and activity on probiotics help understand how these products were evolved and their potential future role in medicine. The objective of this study was to assess the research activity on probiotics in pediatrics using bibliometric indicators and network visualization. Original and review articles on probiotics in pediatrics published worldwide were retrieved from SciVerse, Scopus (1994-2014) and analyzed. VOSviewer was used for network visualization. The total number of documents published on probiotics in pediatrics was 2817. Research activity on probiotics in pediatrics showed approximately 90- fold increase during the study period. Approximately 22 % of published articles originated from USA and has the greatest share, however, Finland ranked first when data were stratified by population or income. The most productive institution in this field was Turku University in Finland with 82 (2.91 %) articles. Half of the prolific authors were also from Finland. Most of the published research activity appeared in Journal of Pediatric Gastroenterology and Nutrition. Most frequently encountered title terms include nutrition, infant formula, necrotizing enetrocolitis, allergy, and diarrhea. The total number of citations for the retreived documents documents was 70991, and the average citation per article was 25.20. Interest in probiotic research and its potential benefits in pediatric ailments is relatively recent but significantly increasing. Bibliometric analysis can be used as an indicator of the importance and growth of probiotic use in pediatrics.

Smoking imposes considerably high economic costs both on the healthcare system as well as on a country as a whole. This study was aimed at systematically reviewing the currently published literature on the direct and indirect costs associated with smoking globally. A systematic review was performed on systematically searched articles from PubMed and Scopus databases published during the period 1990 to 2014. A combination of key terms such as "economic burden", "direct cost", "indirect cost", and smoking, tobacco or cigarette" and "productivity lost was used for the search. Original research article published in English with the age of study population greater than 35 years, at least three smoking-related diseases and reported direct or indirect cost of smoking were the inclusion criteria. Fourteen original articles were included in the review. The cost of outpatient care and premature deaths were found to be the most important cost driver of direct and indirect costs respectively. The study showed that smoking-related diseases were responsible for 1.5 - 6.8 % of the national health system expenditures and 0.22-0.88% of GDP of a country. Our review indicated that the costs of smoking are substantial, and smoking have a significant impact on the economy of a country. Policies such as increasing the taxation on a cigarette are required and should be implemented to reduce the economic burden of smoking.

A growing burden of gunshot injuries demands evidence-based ballistic trauma management. No comprehensive systematic overview of the current knowledge is available to date. This study aims to identify and analyze the most influential publications in the field of orthopedic ballistic trauma research. All databases available in the Thomson Reuters Web of Knowledge were searched to conduct this bibliometrical study. The most cited orthopedic ballistic trauma articles published between 1950 and 2015 were identified by use of a multi-step approach. Publications with ten citations and more were analyzed for citations, journal, authorship, geographic origin, area of research, anatomical site, study type, study category, and level of evidence. Citations of the 128 included studies ranged from 113 to 10. These were published in fifty different journals between 1953 and 2011. Most publications (n=106; 83%) originated from the USA, were retrospective (n=85; 66.4%), level IV studies (n=90; 70.3%), reported on spinal gunshot injuries (n=49; 38.33%) and were published between 1980 and 2000 (n=111; 86.7%). This bibliometric study provides the first comprehensive overview of influential publications in the field of orthopedic ballistic trauma research. More prospective studies and high-quality systematic reviews are needed. Centres with a high burden of gunshot injuries from the developing world need to share their experience in form of international publications, to provide a more comprehensive picture of the global gun-related orthopedic injury burden. bibliometric analysis: level III.

Emergency department injury surveillance and aetiological research: bridging the gap with the two-stage case-control study design.

Hagel, Brent E

2011-04-01

To provide an overview of the two-stage case-control study design and its potential application to ED injury surveillance data and to apply this approach to published ED data on the relation between brain injury and bicycle helmet use. Relevant background is presented on injury aetiology and case-control methodology with extension to the two-stage case-control design in the context of ED injury surveillance. The design is then applied to data from a published case-control study of the relation between brain injury and bicycle helmet use with motor vehicle involvement considered as a potential confounder. Taking into account the additional sampling at the second stage, the adjusted and corrected odds ratio and 95% confidence interval for the brain injury-helmet use relation is presented and compared with the estimate from the entire original dataset. Contexts where the two-stage case-control study design might be most appropriately applied to ED injury surveillance data are suggested. The adjusted odds ratio for the relation between brain injury and bicycle helmet use based on all data (n = 2833) from the original study was 0.34 (95% CI 0.25 to 0.46) compared with an estimate from a two-stage case-control design of 0.35 (95% CI 0.25 to 0.48) using only a fraction of the original subjects (n = 480). Application of the two-stage case-control study design to ED injury surveillance data has the potential to dramatically reduce study time and resource costs with acceptable losses in statistical efficiency.

Edmund Goodwyn and the first description of diving bradycardia.

PubMed

Vega, Jose L

2017-08-01

Diving bradycardia is a primordial oxygen-conserving reflex by which the heart rate of air-breathing vertebrates, including humans, slows down in response to water immersion. Its discovery is attributed to Paul Bert, whose seminal observation was published in 1870 as part of a series of experiments that examined physiological adaptations to asphyxia in ducks and other animals. However, Edmund Goodwyn, a British physician who studied medicine at the University of Edinburgh, had already described this reflex in his doctoral thesis, which was originally published in Latin in 1786 and again in English in 1788. Ironically, even though Goodwyn's work has yet to be recognized in the diving physiology literature, it was referenced in the very publication that contains Bert's original observation. Thus this article brings Goodwyn's work and its historical context to light and argues that he should be credited with the first description of diving bradycardia.

AIM: To understand the changes and development of World Journal of Gastroenterology (WJG) in recent years. METHODS: The Journal Citation Report (JCR) and SCI-E database of the ISI Web of Knowledge were used to search the articles and data of related indices in WJG during 2008-2012. Bibliometric methods were used for statistical analysis of the author’s degree of collaboration, collaboration rate, the first author’s publications, high-productivity authors, the authors’ origins in each year; the distribution of the countries and journals of the authors citing WJG papers was also analyzed. In addition, the indices related to this journal in each year were compared with the data from 6 SCI journals in the field of gastroenterology in the 2012 volume. RESULTS: A total of 4409 papers in WJG were examined in this study. For the period 2008-2012, the self-citation rate was 8.59%, 6.02%, 5.50%, 4.47% and 5.21%. Of a total of 3898 first authors, 3526 published 1 paper, 291 published 2 papers, 59 published 3 papers, and 22 published 4 or more papers. The origin of WJG authors covered the six continents, and the majority came from Asia, Europe and North America. The number of countries of origin of WJG authors was 65, 66, 61, 65 an 60 for the period 2008-2012. Authors from 66 countries cited a total of 3194 of the 4409 papers, and these citations were found in 1140 journals. CONCLUSION: The results suggest that WJG has stayed on the track of normal international publication and all the indices of this journal are stable and reasonable. PMID:24307776

A predictive Bayesian approach to the design and analysis of bridging studies.

2012-09-01

Pharmaceutical product development culminates in confirmatory trials whose evidence for the product's efficacy and safety supports regulatory approval for marketing. Regulatory agencies in countries whose patients were not included in the confirmatory trials often require confirmation of efficacy and safety in their patient populations, which may be accomplished by carrying out bridging studies to establish consistency for local patients of the effects demonstrated by the original trials. This article describes and illustrates an approach for designing and analyzing bridging studies that fully incorporates the information provided by the original trials. The approach determines probability contours or regions of joint predictive intervals for treatment effect and response variability, or endpoints of treatment effect confidence intervals, that are functions of the findings from the original trials, the sample sizes for the bridging studies, and possible deviations from complete consistency with the original trials. The bridging studies are judged consistent with the original trials if their findings fall within the probability contours or regions. Regulatory considerations determine the region definitions and appropriate probability levels. Producer and consumer risks provide a way to assess alternative region and probability choices.

Contextual sensitivity in scientific reproducibility

Van Bavel, Jay J.; Mende-Siedlecki, Peter; Brady, William J.; Reinero, Diego A.

2016-01-01

In recent years, scientists have paid increasing attention to reproducibility. For example, the Reproducibility Project, a large-scale replication attempt of 100 studies published in top psychology journals found that only 39% could be unambiguously reproduced. There is a growing consensus among scientists that the lack of reproducibility in psychology and other fields stems from various methodological factors, including low statistical power, researcher’s degrees of freedom, and an emphasis on publishing surprising positive results. However, there is a contentious debate about the extent to which failures to reproduce certain results might also reflect contextual differences (often termed “hidden moderators”) between the original research and the replication attempt. Although psychologists have found extensive evidence that contextual factors alter behavior, some have argued that context is unlikely to influence the results of direct replications precisely because these studies use the same methods as those used in the original research. To help resolve this debate, we recoded the 100 original studies from the Reproducibility Project on the extent to which the research topic of each study was contextually sensitive. Results suggested that the contextual sensitivity of the research topic was associated with replication success, even after statistically adjusting for several methodological characteristics (e.g., statistical power, effect size). The association between contextual sensitivity and replication success did not differ across psychological subdisciplines. These results suggest that researchers, replicators, and consumers should be mindful of contextual factors that might influence a psychological process. We offer several guidelines for dealing with contextual sensitivity in reproducibility. PMID:27217556

A Bayesian spawning habitat suitability model for American shad in southeastern United States rivers

2012-01-01

Habitat suitability index models for American shad Alosa sapidissima were developed by Stier and Crance in 1985. These models, which were based on a combination of published information and expert opinion, are often used to make decisions about hydropower dam operations and fish passage. The purpose of this study was to develop updated habitat suitability index models for spawning American shad in the southeastern United States, building on the many field and laboratory studies completed since 1985. We surveyed biologists who had knowledge about American shad spawning grounds, assembled a panel of experts to discuss important habitat variables, and used raw data from published and unpublished studies to develop new habitat suitability curves. The updated curves are based on resource selection functions, which can model habitat selectivity based on use and availability of particular habitats. Using field data collected in eight rivers from Virginia to Florida (Mattaponi, Pamunkey, Roanoke, Tar, Neuse, Cape Fear, Pee Dee, St. Johns), we obtained new curves for temperature, current velocity, and depth that were generally similar to the original models. Our new suitability function for substrate was also similar to the original pattern, except that sand (optimal in the original model) has a very low estimated suitability. The Bayesian approach that we used to develop habitat suitability curves provides an objective framework for updating the model as new studies are completed and for testing the model's applicability in other parts of the species' range.

The influence of country of origin on engagement in self-care behaviours following heart surgery: a descriptive correlational study.

PubMed

Fredericks, Suzanne

2012-08-01

The aim of this study was to determine whether an individual's country of origin influenced performance of self-care behaviours after heart surgery. Patients are required to perform self-care behaviours following cardiovascular surgery. Usual care encompasses a patient education initiative that addresses self-care behaviour performance. Within Canada, current heart surgery patient education efforts have been designed and evaluated using homogenous samples that self-identify their country of origin as England, Ireland or Scotland. However, approximately 42·6% of Canadian cardiovascular surgical patients self-identify their country of origin as India or China. Thus, current cardiovascular surgery patient education initiatives may not be applicable to all patients undergoing heart surgery, which may result in decreased patient outcomes such as performance of self-care behaviours. This descriptive study. A convenience sample of 90 patients who underwent heart surgery at one of two university-affiliated teaching hospitals, representing individuals of diverse backgrounds. Point-biserial correlational analysis was conducted to determine the relationship between country of origin and performance of self-care behaviours. Findings indicate individuals who self-identified their country of origin as England or Ireland were associated with a higher score on the number of self-care behaviours performed (p < 0·05) than individuals who self-identified other countries of origin. Self-care behaviours were taught using patient education materials that were designed based on feedback obtained from individuals whose country of origin was England or Ireland. This study provides preliminary evidence to suggest country of origin influences the amount of self-care behaviours individuals will perform. Patient education initiatives should incorporate the values, beliefs, attitudes and customs reflective of an individual's country of origin to enhance the likelihood of producing desired outcomes. © 2012 Blackwell Publishing Ltd.

Statistical software applications used in health services research: analysis of published studies in the U.S

PubMed Central

2011-01-01

Background This study aims to identify the statistical software applications most commonly employed for data analysis in health services research (HSR) studies in the U.S. The study also examines the extent to which information describing the specific analytical software utilized is provided in published articles reporting on HSR studies. Methods Data were extracted from a sample of 1,139 articles (including 877 original research articles) published between 2007 and 2009 in three U.S. HSR journals, that were considered to be representative of the field based upon a set of selection criteria. Descriptive analyses were conducted to categorize patterns in statistical software usage in those articles. The data were stratified by calendar year to detect trends in software use over time. Results Only 61.0% of original research articles in prominent U.S. HSR journals identified the particular type of statistical software application used for data analysis. Stata and SAS were overwhelmingly the most commonly used software applications employed (in 46.0% and 42.6% of articles respectively). However, SAS use grew considerably during the study period compared to other applications. Stratification of the data revealed that the type of statistical software used varied considerably by whether authors were from the U.S. or from other countries. Conclusions The findings highlight a need for HSR investigators to identify more consistently the specific analytical software used in their studies. Knowing that information can be important, because different software packages might produce varying results, owing to differences in the software's underlying estimation methods. PMID:21977990

Recent original scientific contributions published in selected Brazilian periodicals and classifiable under cardiovascular and pulmonary subject categories cover a wide range of sub specialties, both clinical and exprimental. Because they appear in journals with only recently enhanced visibility, we have decided to highlight a number of specific items appeared in four Brazilian journals, because we understand that this is an important subsidy to keep our readership adequately informed. These papers cover extensive sub-areas in both fields. PMID:22189744

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

Bosch, Xavier; Pericas, Juan M; Hernández, Cristina; Doti, Pamela

2013-07-01

To assess financial, nonfinancial and editors' conflicts of interest (COI) disclosure policies among the most influential biomedical journals publishing original research. We conducted a cross-sectional study of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports (JCR) in December 2011. Information relevant to COI and requirements for disclosures that was publicly available on journal websites was collected. While financial COI disclosures were required by 358 (89.7%) and nonfinancial by 280 (70.2%) journals, 155 (38.8%) required editors' disclosures. Journals in the first decile of the JCR classification scored significantly higher than those in the second decile for all disclosure policies. Ninety (22.6%) journals were published by Elsevier and 59 (14.8%) by Wiley-Blackwell, with Elsevier scoring significantly better in financial disclosure policies (P = 0.022). Clinical journals scored significantly higher than basic journals for all disclosure policies. No differences were observed between open-access (n = 25) and nonopen-access (n = 374) journals for any type of disclosure. Somewhat incoherently, authors' disclosure statements were included in some published manuscript in 57.1% of journals without any COI disclosure policies. Authors' financial COI disclosures were required by about 90% of high-impact clinical and basic journals publishing original research. Unlike recent studies showing a significantly lower prevalence of nonfinancial compared with financial disclosures, the former were required by about 70% of journals, suggesting that editors are increasingly concerned about nonfinancial competing interests. Only 40% of journals required disclosure of editors' COI, in conflict with the recommendations of the most influential editors' associations. © 2013 Stichting European Society for Clinical Investigation Journal Foundation.

To study the nature and quality of relationships between gay father families and their surrogates and egg donors and parental disclosure of children's origins. Cross-sectional study. Family homes. Parents in 40 gay father families with 3-9-year-old children born through surrogacy. Administration of a semistructured interview. Relationships between parents, children, surrogates, and egg donors and parental disclosure of children's origins were examined using a semistructured interview. The majority of fathers were content with the level of contact they had with the surrogate, with those who were discontent wanting more contact. Fathers were more likely to maintain relationships with surrogates than egg donors, and almost all families had started the process of talking to their children about their origins, with the level of detail and children's understanding increasing with the age of the child. In gay father surrogacy families with young children, relationships between parents, children, surrogates, and egg donors are generally positive. Copyright © 2016 The Authors.

2015-01-01

Purpose We designed this study to demonstrate recent trends in the proportion of adult hip research in orthopedics, to identify countries leading the adult hip research, and to evaluate the relationship between the economic power of the countries and their contributions. Materials and Methods Studies published in seven select orthopedic journals were retrieved from PubMed. Among them, we determined the number of adult hip studies. The countries-of-origin of adult hip studies, and the economic power of the countries were investigated. Results A total of 7218 orthopedic publications and 1993 (27.6%) addressed adult hip research were identified. Adult hip studies increased from 313 (23.7%) in 2000 to 555 (27.9%) in 2011. Twenty-five countries accounted for 97.6% of the total number of adult hip studies, and gross domestic product correlated with publication volume (Spearman's rho, 0.723; p=0.000). Conclusion Researchers from a limited number of developed countries have published their studies in the adult hip discipline. PMID:25510756

Are K-12 learners motivated in physical education? A meta-analysis.

PubMed

Chen, Senlin; Chen, Ang; Zhu, Xihe

2012-03-01

Previous studies devoted to K-12 learner motivation in physical education share a general assumption that students may lack motivation. This meta-analytic study examined published original studies (n = 79) to determine students' motivation level and the association between motivation and outcomes. Original means of motivation measures were converted and aggregated to determine motivation levels. Correlation effect sizes were calculated to determine the association between motivation and outcome measures. The analyses revealed that K-12 students are motivated regardless of the theoretical constructs used in the studies (M > 50). The correlation effect sizes (r = .20-.30, p < .05) indicate a weak association between motivation and outcome. The findings suggest a need to involve meaningful learning and pedagogy variables in motivation research.

To evaluate the frequency of publication and its associated factors by professors of scientific research in medical schools in Peru. This was a cross-sectional study. We included all teachers of research courses from the 32 medical schools in Peru in 2011. The publication search was conducted using Google Scholar, Scopus and Medline. Both the crude and adjusted prevalence ratios (aPR) were calculated with confidence intervals at 95% using simple and multiple Poisson regression with robust variance. Of the 201 university teachers, 43.8% had never published an article in a journal, 26.9% had an original article published in a journal indexed in Medline and 16.4% did so in the past two years. Only 3% had been corresponding authors in non-Peruvian, indexed journals Factors associated with having an original article published in Medline in the past two years were: being under 40 years of age (aPR 2.97, 95% CI: 1.21-7.32), being a professor at a university where a final thesis is required for graduation (aPR 8.84, 95% CI: 2.60-30.12) and working for a highly productive university (aPR 3.24, 95% CI: 1.03-10.20). The frequency of publication of research faculty in medical schools in Peru is low. Young university teachers and those working at scientifically productive universities were more likely to publish in an indexed journal.

A significant portion of radiation treatment (30-40%) is delivered with palliative intent. Given the frequency of palliative care (PC) in radiation oncology, we determined the patterns of research focusing on symptom control and palliative care (SCPC) in two prominent radiation oncology journals from 2005-2014. Original research manuscripts published from 2005-2014 in the International Journal of Radiation Oncology *Biology* Physics (Red Journal) and the Radiotherapy and Oncology Journal (Green Journal) were reviewed to categorize articles as PC and/or SCPC. Articles were categorized as PC if it pertained to any aspect of treatment of metastatic cancer, and as SCPC if symptom control in the metastatic cancer setting was the goal of the research inquiry and/or any domain of palliative clinical practice guidelines was the goal of research inquiry. From 2005-2014, 4.9% (312/6,386) of original research articles published in the Red Journal and 3.5% (84/2,406) published in the Green Journal pertained to metastatic cancer, and were categorized as PC. In the Red Journal, 1.3% (84/6,386) of original research articles were categorized as SCPC; 1.3% (32/2,406) of articles in the Green Journal were categorized as SCPC. There was no trend observed in the proportion of SCPC articles published over time in the Red Journal (P=0.76), the Green Journal (P=0.48), or both journals in aggregate (P=0.38). Despite the fact that palliative radiotherapy is a critical part of radiation oncology practice, PC and SCPC-focused original research is poorly represented in the Red Journal and the Green Journal.

Bronchial asthma and chronic obstructive pulmonary disease: research activity in Arab countries

PubMed Central

2014-01-01

Background Chronic respiratory diseases, like bronchial asthma and chronic obstructive pulmonary disease (COPD), are a worldwide health problem. Quantitative and qualitative assessment of asthma and COPD-related research from Arab countries has not been explored and there are few internationally published reports on such field. The main objectives of this study were to analyze research output originating from Arab countries in the field of bronchial asthma and COPD. Methods Original scientific articles or reviews published from the 22 Arab countries were screened using specific words pertaining to asthma and COPD using Scopus database and search engine. Research productivity was evaluated based on: (a) total and trends of contribution of each Arab country to asthma and COPD research and (b) journals in which researchers from Arab countries published their research. Results The total number of original research and review articles published globally about bronchial asthma and COPD was 163,964. The leading country in bronchial asthma and COPD research was United States of America (38,632; 23.56%). Worldwide, Turkey ranked 19th while Israel and Iran ranked 25th and 29th respectively. Among Arab countries, Egypt and Kingdom of Saudi Arabia came on positions 39th and 43rd, respectively. A total of 1,304 documents about bronchial asthma and COPD were published from Arab countries which represents 0.8% of the global research output. Research in bronchial asthma was almost double that in COPD. Research from Arab countries was low and showed a significant increase after 2000. Approximately 12% of research activity in asthma and COPD from Arab countries was published in Saudi Medical Journal, Annals of Saudi Medicine, Eastern Mediterranean Health Journal and Tunisie Medicale. Kingdom of Saudi Arabia, with a total publication of 353 (27.07%) ranked first among the Arab countries while University of Kuwait was the most productive institution with a total of 123 (9.43%) documents. Conclusions The present data showed relatively low research productivity about bronchial asthma and COPD in Arab countries. Research output can be improved by investing more in international and national collaborative research projects in the field of asthma and COPD. PMID:25050176

Trends in Publications in Radiology Journals Designated as Relating to Patient-Centered Care.

PubMed

Rosenkrantz, Andrew B; Rawson, James V

2017-05-01

To assess trends in publications in radiology journals designated as dealing with patient-centered care. PubMed was searched for articles in radiology journals for which the article's record referenced patient-centered/patient-centric care. Among these, original research articles were identified and assigned major themes. Trends were assessed descriptively. A total of 115 articles in radiology journals designated as dealing with patient-centered care were identified, including 40 original research articles. The number of articles annually ranged from 0 to 4 in 2000-2008, 5 to 9 in 2010-2012, 14 to 15 in 2013-2014, and 25 in 2015. Only four radiology journals had published more than one of the original research articles. Original research articles' most common themes were: optimization of patients' access to reports and images (n=7); patients' examination experience (5); image evaluation (n=4); radiologists meeting with patients (n=4); improving patients' knowledge of imaging (n=3); examination wait times/efficiency (n=3); examination utilization/appropriateness (n=3); and IT enhancements (n=3). A total of 13 of 40 original research articles solicited opinions from patients. One study involved patients in educating trainees regarding patient-centered care. No study involved patients in system-level decisions regarding health care design and delivery. Articles dealing with patient-centered care in radiology are increasing, though they remain concentrated in a limited number of journals. Though major themes included image/report access, patient experiences, and radiologists meeting with patients, many studies dealt with less clearly patient-centric topics such as examination interpretation, while inclusion of patients in systems design was lacking. Further research in radiology is encouraged to target a broader range of ideals of patient-centered care, such as diversity, autonomy, and compassion, and to incorporate greater patient engagement.

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

Twelve-lead electrocardiogram (ECG) criteria for epicardial ventricular tachycardia (VT) origins have been described. In patients with structural heart disease, the ability to predict an epicardial origin based on QRS morphology is limited and has been investigated only for limited regions in the heart. The purpose of this study was to determine whether a computerized algorithm is able to accurately differentiate epicardial vs endocardial origins of ventricular arrhythmias. Endocardial and epicardial pace-mapping were performed in 43 patients at 3277 sites. The 12-lead ECGs were digitized and analyzed using a mixture of gaussian model (MoG) to assess whether the algorithm was able to identify an epicardial vs endocardial origin of the paced rhythm. The MoG computerized algorithm was compared to algorithms published in prior reports. The computerized algorithm correctly differentiated epicardial vs endocardial pacing sites for 80% of the sites compared to an accuracy of 42% to 66% of other described criteria. The accuracy was higher in patients without structural heart disease than in those with structural heart disease (94% vs 80%, P = .0004) and for right bundle branch block (82%) compared to left bundle branch block morphologies (79%, P = .001). Validation studies showed the accuracy for VT exit sites to be 84%. A computerized algorithm was able to accurately differentiate the majority of epicardial vs endocardial pace-mapping sites. The algorithm is not region specific and performed best in patients without structural heart disease and with VTs having a right bundle branch block morphology. Copyright © 2014 Heart Rhythm Society.

2018-05-02

To compile and analyze the published studies on cell therapy for type 2 diabetes mellitus (T2DM) to obtain a better insight into management of T2DM that involved stem cell therapy. We searched all published studies in Pubmed/Medline, and Cochrane library, using keywords: 'stem cell' AND 'therapy' AND 'diabetes type 2'. original articles on the use of stem cells in humans with T2DM. articles in the non-English literature, studies on T2DM complications that did not assess both adverse events and any of the common diabetes study outcomes. type of study, number of cases, and all data that were related to outcome and adverse events. Data were analyzed descriptively to conclude the possible cause of adverse reactions, and which protocols gave a satisfactory outcome. We collected 26 original articles, out of which 17 studies did not have controls and were classified as case reports, while there were 8 studies that were controlled clinical trials. Most studies used autologous bone marrow mononuclear cells (BM-MNCs) or autologous or allogeneic mesenchymal stem cells (MSCs) from various sources. Adverse events were mild and mostly intervention related. Efficacy of autologous BM-MNCs that were given via interventional route was comparable to Wharton jelly or umbilical cord MSCs that were given via intravenous (IV), Intra muscular (IM), or subcutaneous (SC) route. Further controlled studies that compare BM-MNCs to BM-MSCs or WJ-MSCs or UCSCs are recommended to prove their comparable efficacy. In addition, studies that compare various routes of administration (IV, IM or SC) versus the more invasive interventional routes are needed.

Introduction to positivism, interpretivism and critical theory.

PubMed

Ryan, Gemma

2018-03-16

There are three commonly known philosophical research paradigms used to guide research methods and analysis: positivism, interpretivism and critical theory. Being able to justify the decision to adopt or reject a philosophy should be part of the basis of research. It is therefore important to understand these paradigms, their origins and principles, and to decide which is appropriate for a study and inform its design, methodology and analysis. To help those new to research philosophy by explaining positivism, interpretivism and critical theory. Positivism resulted from foundationalism and empiricism; positivists value objectivity and proving or disproving hypotheses. Interpretivism is in direct opposition to positivism; it originated from principles developed by Kant and values subjectivity. Critical theory originated in the Frankfurt School and considers the wider oppressive nature of politics or societal influences, and often includes feminist research. This paper introduces the historical context of three well-referenced research philosophies and explains the common principles and values of each. The paper enables nurse researchers to make informed and rational decisions when embarking on research. ©2018 RCN Publishing Company Ltd. All rights reserved.

As we found no recent published reports on the amount and kind of research published from Danish hospitals without university affiliation, we have found it relevant to conduct a bibliometric survey disclosing these research activities. We retrieved all scientific papers published in the period 2000-2009 emanating from all seven Danish non-university hospitals in two regions, comprising 1.8 million inhabitants, and which were registered in a minimum of one of the three databases: PubMed MEDLINE, Thomson Reuters Web of Science and Elsevier's Scopus. In 878 of 1,252 papers, the first and/or last author was affiliated to a non-university hospital. Original papers made up 69% of these publications versus 86% of publications with university affiliation on first or last place. Case reports and reviews most frequently had authors from regional hospitals as first and/or last authors. The total number of publications from regional hospitals increased by 48% over the 10-year period. Publications were cited more often if the first or last author was from a university hospital and even more so if they were affiliated to foreign institutions. Cardiology, gynaecology and obstetrics, and environmental medicine were the three specialities with the largest number of regional hospital publications. A substantial number of scientific publications originate from non-university hospitals. Almost two thirds of the publications were original research published in international journals. Variations between specialities may reflect local conditions. not relevant. not relevant.

Darwin and barnacles.

PubMed

Deutsch, Jean

2010-02-01

In this essay, I discuss the origin of Charles Darwin's interest in cirripedes (barnacles). Indeed, he worked intensively on cirripedes during the years in which he was developing the theory that eventually led to the publication of The Origin of Species. In the light of our present knowledge, I present Darwin's achievements in the morphology, systematics and biology of these small marine invertebrates, and also his mistakes. I suggest that the word that sheds the most light here is homology, and that his mistakes were due to following Richard Owen's method of determining homologies by reference to an ideal archetype. I discuss the ways in which his studies on cirripedes influenced the writing of The Origin. 2009 Académie des sciences. Published by Elsevier SAS. All rights reserved.

Our focus for this exploration is Peirce's paper The "Fixation of Belief" (FOB), originally published in 1877 in "Popular Science Monthly". We begin by examining Peirce's assertion that the study of logic is essential for understanding…

Stem cells present in the adult brain are regulated by neuronal activity; malignant gliomas, which most likely originate from this population of cells, could also be regulated in this manner. A recent study by Venkatesh et al. published in Cell has identified Neuroligin-3 (NLGN3) as a mitogen promoting high-grade glioma growth.

Aquatic Habits of Cetacean Ancestors: Integrating Bone Microanatomy and Stable Isotopes.

PubMed

Cooper, Lisa Noelle; Clementz, Mark T; Usip, Sharon; Bajpai, Sunil; Hussain, S Taseer; Hieronymus, Tobin L

2016-12-01

The earliest cetaceans were interpreted as semi-aquatic based on the presence of thickened bones and stable oxygen isotopes in tooth enamel. However, the origin of aquatic behaviors in cetacean relatives (e.g., raoellids, anthracotheres) remains unclear. This study reconstructs the origins of aquatic behaviors based on long bone microanatomy and stable oxygen isotopes of tooth enamel in modern and extinct cetartiodactylans. Our findings are congruent with published accounts that microanatomy can be a reliable indicator of aquatic behaviors in taxa that are obligatorily aquatic, and also highlight that some "semi-aquatic" behaviors (fleeing into the water to escape predation) may have a stronger relationship to bone microanatomy than others (herbivory in near-shore aquatic settings). Bone microanatomy is best considered with other lines of information in the land-to-sea transition of cetaceans, such as stable isotopes. This study extends our understanding of the progression of skeletal phenotypes associated with habitat shifts in the relatives of cetaceans. © The Author 2016.

Evaluation Criteria of Noninvasive Telemonitoring for Patients With Heart Failure: Systematic Review.

PubMed

Farnia, Troskah; Jaulent, Marie-Christine; Steichen, Olivier

2018-01-16

Telemonitoring can improve heart failure (HF) management, but there is no standardized evaluation framework to comprehensively evaluate its impact. Our objectives were to list the criteria used in published evaluations of noninvasive HF telemonitoring projects, describe how they are used in the evaluation studies, and organize them into a consistent scheme. Articles published from January 1990 to August 2015 were obtained through MEDLINE, Web of Science, and EMBASE. Articles were eligible if they were original reports of a noninvasive HF telemonitoring evaluation study in the English language. Studies of implantable telemonitoring devices were excluded. Each selected article was screened to extract the description of the telemonitoring project and the evaluation process and criteria. A qualitative synthesis was performed. We identified and reviewed 128 articles leading to 52 evaluation criteria classified into 6 dimensions: clinical, economic, user perspective, educational, organizational, and technical. The clinical and economic impacts were evaluated in more than 70% of studies, whereas the educational, organizational, and technical impacts were studied in fewer than 15%. User perspective was the most frequently covered dimension in the development phase of telemonitoring projects, whereas clinical and economic impacts were the focus of later phases. Telemonitoring evaluation frameworks should cover all 6 dimensions appropriately distributed along the telemonitoring project lifecycle. Our next goal is to build such a comprehensive evaluation framework for telemonitoring and test it on an ongoing noninvasive HF telemonitoring project. ©Troskah Farnia, Marie-Christine Jaulent, Olivier Steichen.

The full-text publication of abstracts presented at any given scientific meeting in peer-reviewed journals is accepted as a measure of scientific quality of that particular meeting. The aim of this study is to determine the full-text publication rate of abstracts presented at the 2005 Scientific Meeting of the Undersea and Hyperbaric Medical Society (UHMS). We identified the scientific abstracts presented at the 2005 UHMS meeting and searched the PubMed database (June 2005 to July 2010) for their corresponding full-text publication. We recorded the following parameters for each of the abstracts: number of authors, number of centers involved in the study, statistical methods used, country of origin of the study, study type, and subject of the abstract. We recorded the time to publication and the title of the journal if the abstract had been published in a peer-reviewed journal. Overall, we identified 187 abstracts presented at the 2005 UHMS meeting. Two of the abstracts were excluded from the study because they had been retracted from the meeting and six more because they had been already published as full-text articles at the time the meeting was held. Of the 179 abstracts, 62 (34.6%) were published as full-text articles within the succeeding five years. The mean (+/- SD) time to publication was 18.5 (+/- 13.6) months. Multivariate analysis with logistic regression identified "country of origin" and "the subject of the abstract" as independent predictors of full-text publication. We found that only one-third of the abstracts presented at the 2005 UHMS meeting were published as full-text articles within the succeeding five years. Although this rate is consistent with similar studies from various disciplines, further research is needed to identify the specific barriers to full-text publication of abstracts in the field of underwater and hyperbaric medicine.

We evaluated the authorship count of all original research and review articles published in prominent Urology journals to trend patterns in authorship over the last decade. Secondarily, we evaluated bibliometric assessments and sought to understand whether authorship count was associated with citation rate and each article's field-normalized measure of impact. Information on authorship count, date of publication, study type, journal of publication, citation rate, and relative citation ratio (RCR) was collected for all original research and review articles published in European Urology, Journal of Urology, Urology , and British Journal of Urology International between 2006 and 2016. We examined trends in authorship count over the past decade, as well as between journals and article types. 21,336 articles were analyzed, of which 19,527 (91.5%) were original research and 1,809 (8.5%) were review articles. Overall, number of authors increased 46.1% from 2006 to 2016. Authorship counts in original research articles increased by an average of 2.45 per manuscript (43.3% increase) over the decade analyzed. More dramatically, authorship counts in review articles increased by an average of 3.14 per manuscript (92.6% increase). Articles with higher authorship counts were associated with more citations and greater RCR (r=0.13, p<0.001). There is a global trend towards more authors per article in urology publications-in both original research publications and review articles, and across each of the individual journals evaluated. An increase in author count has also been associated with increased citations and measures of article impact.

Malformation or dysmorphic syndromes are conditions that are defined by the combination of a set of major and minor malformations that generally have a genetic origin. We investigated the early Spanish descriptions of a large number of sydromes. We started the study from the definition in a classic treatise on the subject. Among the 60 selected syndromes studied, at least two articles of each syndrome among those published in Spain and for the first time were listed in the Spanish Medical Index. For years prior to 1970, it expanded The search was expanded to PubMed, for the years before 1970. We collected 64 articles that referred to 58 syndromes. Four articles were written during the first half of the twentieth century. Almost half of the works (n=30) appeared in the 1970's. The papers were published in ten Spanish pediatric, nine Spanish non-pediatric, three pediatric non-Spanish and two non-Spanish non-pediatric Journals. The Journals with the most articles published were Anales de Pediatría y Revista Española de Pediatría. The hospitals where the articles originate more often were Hospital La Paz, Madrid and Hospital Clinic, Barcelona. The rest of the works were written in 30 pediatric hospitals and two more in non-Spanish hospitals. The number of authors increased with the passage of time. Although there were potential limitations, we have identified what may be the first descriptions of 58 syndromes, among the 60 chosen initially. Copyright © 2012 Asociación Española de Pediatría.

Cell of Origin and Cancer Stem Cells in Tumor Suppressor Mouse Models of Glioblastoma.

2016-01-01

The cellular origins and the mechanisms of progression, maintenance of tumorigenicity, and therapeutic resistance are central questions in the glioblastoma multiforme (GBM) field. Using tumor suppressor mouse models, our group recently reported two independent populations of adult GBM-initiating central nervous system progenitors. We found different functional and molecular subtypes depending on the tumor-initiating cell lineage, indicating that the cell of origin is a driver of GBM subtype diversity. Using an in vivo model, we also showed that GBM cancer stem cells (CSCs) or glioma stem cells (GSCs) contribute to resistance to chemotherapeutic agents and that genetic ablation of GSCs leads to a delay in tumor progression. These studies are consistent with the cell of origin and CSCs as critical regulators of the pathogenesis of GBM. © 2016 Alcantara Llaguno et al; Published by Cold Spring Harbor Laboratory Press.

Bibliometric studies are increasingly being used for research assessments. Bibliometric indicators involve the application of statistical methods to scientific publications to obtain the bibliographics for each journal. The main objective of this study was to conduct a bibliometric evaluation of Human & Experimental Toxicology retrieved from the Scopus database. This study obtained data from Scopus published from 1 January 2003 till 31 December 2012. The keywords entered in Scopus to accomplish the objective of this study were 'Human', 'Experimental' and 'Toxicology' as 'Source Title'. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies by analysing (a) total and trends in Human & Experimental Toxicology contributions in research between 2003 and 2012; (b) Human & Experimental Toxicology authorship patterns and productivity; (c) collaboration patterns; and (d) the citations received by the publications. There were 1229 research articles published in Human & Experimental Toxicology. Of the articles included, 947 (77.1%) were original articles and 104 (8.5%) were review articles. The Hirsch-index of the retrieved documents was 35. The largest number of publications in Human & Experimental Toxicology was from the United States (19.6%), followed by India (12.8%) and Turkey (10.9%). The total number of citations was 9119, with a median (interquartile range) of 3 (1-9) in 6797 documents. The highest median (interquartile range) number of citations was 8 (2.7-12.7) for France, followed by 7.5 (2-22.5) for Iran and 6 (3-13.5) for the United Kingdom. The country most often citing articles that were published in Human & Experimental Toxicology was the United States, which made citations in 1508 documents, followed by India with citations in 792 documents. The documents in Human & Experimental Toxicology focus principally on original data, with very few review articles. Review articles tend to have higher citation rates than original articles, and hence, the editors and authors of Human & Experimental Toxicology might usefully promote the submission of reviews in the future to improve the impact of the journal.

Preapproval and postapproval availability of published comparative efficacy research on biological agents.

PubMed

Thomas, Rachel Hutchins; Freeman, Maisha Kelly; Hughes, Peter J

2013-07-15

Preapproval and postapproval availability of published comparative efficacy studies on biological agents approved between 2000 and 2010 was investigated. Approval packages published on the Food and Drug Administration (FDA) website were examined for all biological agents approved between 2000 and 2010 to determine if comparative efficacy studies were available at the time of FDA approval. The availability of comparative efficacy studies published subsequent to approval was determined by searching PubMed for randomized, active-controlled experimental or observational study designs that measured efficacy as the primary endpoint and were relevant to the original FDA-approved indication. From 2000 to 2010, 107 biological agents were approved by FDA. Of the biological agents with alternative treatments, 54.6% had comparative efficacy data available at the time of approval. Although standard-reviewed biological agents were more likely to have comparative efficacy trials included in the FDA approval packages than priority-reviewed biological agents, statistically significant differences are unlikely. Subsequent to approval, 58.1% of biological agents had at least one published comparative efficacy trial, representing a 3.5% absolute increase in the availability of comparative efficacy studies since the time of approval. Vaccines and biological agents in the hematologic diseases, oncology, and miscellaneous diseases classes had fewer published postapproval comparative efficacy studies per agent compared with the overall group of biological agents. Nearly half of all biological agents approved for marketing between 2000 and 2010 lacked publicly accessible, active-controlled efficacy studies at the time of drug approval; a slightly greater proportion of biological agents had comparative efficacy data published subsequent to their approval.

Jack Healy Remembers - Anecdotal Evidence for the Origin of the Approximate 24-hour Urine Sampling Protocol Used for Worker Bioassay Monitoring

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

Carbaugh, Eugene H.

2008-10-01

The origin of the approximate 24-hour urine sampling protocol used at Hanford for routine bioassay is attributed to an informal study done in the mid-1940s. While the actual data were never published and have been lost, anecdotal recollections by staff involved in the initial bioassay program design and administration suggest that the sampling protocol had a solid scientific basis. Numerous alternate methods for normalizing partial day samples to represent a total 24-hour collection have since been proposed and used, but no one method is obviously preferred.

Partial D-loop sequences of museum specimens of brown trout and marble trout (Salmo trutta species complex) collected from Mediterranean rivers in the late 19th century were analysed to help to describe the native distribution of these species. All the individuals studied carried native haplotypes, the geographic distribution of which is consistent with published data. These results indicate that museum specimens from the 19th century could represent an opportunity to get a picture of the original genetic diversity distribution of this species complex. © 2017 The Fisheries Society of the British Isles.

Ferdinand von Mueller's interactions with Charles Darwin and his response to Darwinism.

Lucas, A M

2010-01-01

Although Ferdinand Mueller (later von Mueller), Government Botanist of Victoria, opposed Darwin's theories when "On the origin of species" was published, there has been little detailed study of the nature of Mueller's opposition from 1860, when he received a presentation copy of "Origin," to his death in 1896. Analysis of Mueller's correspondence and publications shows that he remained a theist and misunderstood key aspects of Darwin's theory. However, Mueller did come to accept that natural selection could operate within a species, although never accepting it could produce speciation. Despite these differences he retained a cordial relationship with Darwin.

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

2018-04-01

CeO2/CdS nanocomposites were synthesized using a two-step hydrothermal technique. The effects of precursor concentration on the optical and structural properties of the CeO2/CdS nanoparticles were systematically studied. The morphology, composition and the structure of the CeO2/CdS nanocomposite powder were studied by scanning electron microscopy (SEM), energy dispersive X-ray spectrum analysis (EDXA) and X-ray diffraction (XRD), respectively. The optical properties of CeO2/CdS nanocomposites were studied by UV-vis absorption and photoluminescence (PL) spectroscopy. The optical band gaps of the CeO2/CdS nanopowders ranged from 2.34 eV to 2.39 eV as estimated from the UV-vis absorption. In the room temperature photoluminescence spectrum of CeO2/CdS nanopowder, a strong blue emission band was observed at 400 nm. Since the powder shows strong visible luminescence, it may be used as a blue phosphor in future. The original article published with this DOI was submitted in error. The correct article was inadvertently left out of the original submission. This has been rectified and the correct article was published online on 16 April 2018.

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

There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India.

Angeletti, Silvia; Lo Presti, Alessandra; Cella, Eleonora; Ciccozzi, Massimo

2016-07-01

Nipah virus (NiV) is a member of the genus Henipavirus of the family Paramyxoviridae, characterized by high pathogenicity and endemic in South Asia. It is classified as a Biosafety Level-4 (BSL-4) agent. The case-fatality varies from 40% to 70% depending on the severity of the disease and on the availability of adequate healthcare facilities. At present no antiviral drugs are available for NiV disease and the treatment is just supportive. Phylogenetic and evolutionary analyses can be used to help in understanding the epidemiology and the temporal origin of this virus. This review provides an overview of evolutionary studies performed on Nipah viruses circulating in different countries. Thirty phylogenetic studies have been published from 2000 to 2015 years, searching on pub-med using the key words 'Nipah virus AND phylogeny' and twenty-eight molecular epidemiological studies from 2006 to 2015 have been performed, typing the key words 'Nipah virus AND molecular epidemiology'. Overall data from the published study demonstrated as phylogenetic and evolutionary analysis represent promising tools to evidence NiV epidemics, to study their origin and evolution and finally to act with effective preventive measure.

This study aimed at examining resource partitioning both at the inter- and intraspecific levels between paired chondrostome fishes: Chondrostoma nasus, the nase, C. toxostoma, the sofie, and their hybrid. The study was performed in the south of France and concerned a main river (the Durance River) and a tributary (the Buech River). In these rivers, C. nasus was an introduced species, originating in central Europe, and C. toxostoma was an endemic congener, in the south of France. Stable isotope analysis was used to analyse trophic and spatial niches. Isotopic differences indicated that individuals from the three taxa (C. nasus, C. toxostoma and their hybrid) have different spatial origins. At the interspecific level, the different chondrostomes originating from the Buech River showed a high level of trophic niche overlap. At the intraspecific level, nase individuals originating from the different spatial origins showed a resource polymorphism; differences in morphology were associated with variation in behaviour and life history traits. Their coexistence was a likely outcome of resource polymorphism. This study provides an example of the importance of considering the link between intra- and interspecific interactions to gain an understanding of the mechanisms driving the coexistence of species-pairs.

The botanical origin of a Chinese crude drug Ma-huang in ancient China and the origin of Japanese Ma-huang were herbologically studied. The results showed that the plants of Ephedra sinica Stapf, E. intermedia Schrenk & C. A. Meyer and E. equisetina Bunge were used as Ma-huang in China, and the first species was considered to be of high quality. The characters of Mao-zhou Ma-huang and Tong-zhou Ma-huang printed in Tu-jing-ben-cao, published in the Song Dynasty in China, were identified as E. likiangensis Florin and E. intermedia, respectively, and both species were recognized as excellent Ma-huang in the Ming Dynasty. The word origin of Katsune-kusa, the Japanese name for Ma-huang in the Heian Era, was etymologically considered as meaning the plant having reddish brown roots. In Japan, the plant of Equisetum ramosissimum Desf. var.japonicum Milde, of the family Equisetaceae, was substituted for Ma-huang in the middle of Edo Era, and it was designated that this action was based on the confusion of Ephedra plants and Equisetum plants those days in China.

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

The Republic of Ireland has always had an influence on medicine and has produced many renowned doctors who have helped shape its history. Furthermore, many clinical articles that have originated from Ireland have changed clinical practice throughout the world. The Irish have also had an impact on the plastic surgery literature yet it has never specifically been analyzed before. The purpose of this study was to identify and analyze all papers that have originated from the plastic surgery units in the Republic of Ireland in the medical literature over the past 21 years. Twenty-four well-known plastic surgery, hand surgery and burns journals were selected for this study. By utilizing Scopus, the largest abstract and citation database of peer-reviewed literature, we analyzed each of our chosen 24 journals looking for Irish publications. Each paper was examined for article type, authorship, year of publication, institution of origin and level of evidence. Papers from the Republic of Ireland were published in 20 of the 24 journals over the past 21 years. A total of 245 articles from Ireland were published in the plastic surgery, hand surgery and burns literature over the 21-year period. Of these, 111 were original articles and 73 were case reports. The institution that published the most papers over the past 21 years was University Hospital Galway (66 publications) followed by Cork University Hospital with 54 papers. The journal with the most Irish articles was the Journal of Plastic, Reconstructive and Aesthetic Surgery with 56 papers. 2014 was the year with the most publications (28 papers). Authorship numbers also increased over time as the average number of authors in 1994 was 3.5, whereas it was 5.54 in 2014. The number of publications per year continues to increase along with authorship numbers. This mirrors the trend in other specialties. Publications are now no longer required for selection on to a higher surgical training scheme. There is now a fear that the academic output of trainees will decrease as a consequence. To prevent this, each unit must actively support and encourage research activity with their trainees.

Compilation of PZC and IEP of sparingly soluble metal oxides and hydroxides from literature.

PubMed

Kosmulski, Marek

2009-11-30

The values of PZC and IEP of metal oxides reported in the literature are affected by the choice of the specimens to be studied. The specimens, which have PZC and IEP similar to the "recommended" value, are preferred by the scientists. The biased choice leads to accumulation of results for a few specimens, and the other specimens are seldom studied or they are subjected to washing procedures aimed at shift of the original IEP toward the "recommended" value. Taking the average or median of all published PZC and IEP for certain oxide as the "recommended" value leads to substantiation of previously published results due to overrepresentation of certain specimens in the sample.

Biomedical research has grown considerably in the last few decades, and the authorship characteristics of the dental literature as a whole and of its specialty fields has changed significantly. Unfortunately, the bibliometrics of the periodontal literature have not been thoroughly investigated. The aim of this study is to investigate the bibliometrics of periodontal literature, assessing the geographic origin, study design, and topics investigated in periodontal research published from 1995 to 2010. Articles published in periodontal journals during 1995 to 2010 were retrieved through hand search. Inclusion/exclusion criteria were applied. The following variables were extrapolated from each article: number of authors, study design, topic investigated, financial support, and geographic origin. The general linear model assessed the influence of independent variables on number of authors per article, and χ(2) test assessed the statistical difference of the variables over years 1995 to 2010. A total of 2,260 articles were reviewed; 2,076 met the inclusion criteria. The number of authors per article increased (P <0.001) from 4.0 (1995) to 5.1 (2010). The proportion of articles published from North America and Europe decreased (P <0.001) from 84.3% (1995) to 58.6% (2010), whereas for Asia and South America the article proportion increased (P <0.001) from 13.8% (1995) to 40% (2010). Research targeting prevention and treatment of periodontal disease is decreasing (P <0.001) in favor of implant-related research. Governmental research funding is increasing (P <0.001). Periodontal research significantly changed during the last 15 years.

Publication of a study is the end point of the process to contribute to the literature and confirm the scientific value of the study. Publication rates of the abstracts presented at the annual meetings of neurosurgery have been studied, previously. However, publication rates of the abstracts presented at the annual meetings of pediatric neurosurgery have not been reported, yet. We evaluated abstracts presented at the 38th annual meeting of the International Society for Pediatric Neurosurgery (ISPN) held in South Korea, 2010. We conducted this cross-sectional study by reviewing the abstracts presented at the annual meeting of the ISPN, 2010. Titles and authors of the abstracts were surveyed using Google Scholar and PubMed/MEDLINE. Time to publication, origin of the study, journal name in which the study has been accepted and published, and type of study has been analyzed for each abstract. The abstract booklet included 235 abstracts, consisted of 128 oral presentations (54%) and 107 electronic posters (46%). Fifty-nine (46%) of the oral presentations were published in a peer-reviewed journal. Laboratory studies were more likely to be published when compared to the clinical studies (72 vs. 39%). Thirty-two (30%) of the electronic posters were published in peer-reviewed journals. Most of the published abstracts were from Asia and Europe. Most of the abstracts were published in Child's Nervous System and Journal of Neurosurgery: Pediatrics. Publication rates of the abstracts presented at annual meeting of the ISPN were comparable to the other similar congresses. Oral presentations were more likely to be published. High publication rates of the abstracts presented at the annual meeting of the ISPN suggested that the meeting had a high scientific value.

Review and critical appraisal of studies mapping from quality of life or clinical measures to EQ-5D: an online database and application of the MAPS statement.

2018-02-12

The Health Economics Research Centre (HERC) Database of Mapping Studies was established in 2013, based on a systematic review of studies developing mapping algorithms predicting EQ-5D. The Mapping onto Preference-based measures reporting Standards (MAPS) statement was published in 2015 to improve reporting of mapping studies. We aimed to update the systematic review and assess the extent to which recently-published studies mapping condition-specific quality of life or clinical measures to the EQ-5D follow the guidelines published in the MAPS Reporting Statement. A published systematic review was updated using the original inclusion criteria to include studies published by December 2016. We included studies reporting novel algorithms mapping from any clinical measure or patient-reported quality of life measure to either the EQ-5D-3L or EQ-5D-5L. Titles and abstracts of all identified studies and the full text of papers published in 2016 were assessed against the MAPS checklist. The systematic review identified 144 mapping studies reporting 190 algorithms mapping from 110 different source instruments to EQ-5D. Of the 17 studies published in 2016, nine (53%) had titles that followed the MAPS statement guidance, although only two (12%) had abstracts that fully addressed all MAPS items. When the full text of these papers was assessed against the complete MAPS checklist, only two studies (12%) were found to fulfil or partly fulfil all criteria. Of the 141 papers (across all years) that included abstracts, the items on the MAPS statement checklist that were fulfilled by the largest number of studies comprised having a structured abstract (95%) and describing target instruments (91%) and source instruments (88%). The number of published mapping studies continues to increase. Our updated database provides a convenient way to identify mapping studies for use in cost-utility analysis. Most recent studies do not fully address all items on the MAPS checklist.

To examine changes in representation of women among first authors of original research published in high impact general medical journals from 1994 to 2014 and investigate differences between journals. Observational study. All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine, The BMJ, JAMA, The Lancet, and the New England Journal of Medicine (NEJM) for one issue every alternate month from February 1994 to June 2014. Time and journal of publication. Prevalence of female first authorship and its adjusted association with time of publication and journal, assessed using a multivariable logistic regression model that accounted for number of authors, study type and specialty/topic, continent where the study was conducted, and the interactions between journal and time of publication, study type, and continent. Estimates from this model were used to calculate adjusted odds ratios against the mean across the six journals, with 95% confidence intervals and P values to describe the associations of interest. The gender of the first author was determined for 3758 of the 3860 articles considered; 1273 (34%) were women. After adjustment, female first authorship increased significantly from 27% in 1994 to 37% in 2014 (P<0.001). The NEJM seemed to follow a different pattern, with female first authorship decreasing; it also seemed to decline in recent years in The BMJ but started substantially higher (approximately 40%), and The BMJ had the highest total proportion of female first authors. Compared with the mean across all six journals, first authors were significantly less likely to be female in the NEJM (adjusted odds ratio 0.68, 95% confidence interval 0.53 to 0.89) and significantly more likely to be female in The BMJ (1.30, 1.01 to 1.66) over the study period. The representation of women among first authors of original research in high impact general medical journals was significantly higher in 2014 than 20 years ago, but it has plateaued in recent years and has declined in some journals. These results, along with the significant differences seen between journals, suggest that underrepresentation of research by women in high impact journals is still an important concern. The underlying causes need to be investigated to help to identify practices and strategies to increase women's influence on and contributions to the evidence that will determine future healthcare policies and standards of clinical practice.

2001-01-01

The "National Atlas of the United States of America®", published by the U.S. Geological Survey (USGS) in 1970, is out of print, but many of its maps can be purchased separately. Maps that span facing pages in the atlas are printed on one sheet. Maps dated after 1970 and before 1997 are either revisions of original atlas maps or new maps published in the original atlas format. The USGS and its partners in government and industry began work on a new "National Atlas" in 1997. Though most new atlas products are designed for the World Wide Web, we are continuing our tradition of printing high-quality maps of America. In 1998, the first completely redesigned maps of the "National Atlas of the United States®" were published.

Applying human factors principles to alert design increases efficiency and reduces prescribing errors in a scenario-based simulation.

To apply human factors engineering principles to improve alert interface design. We hypothesized that incorporating human factors principles into alerts would improve usability, reduce workload for prescribers, and reduce prescribing errors. We performed a scenario-based simulation study using a counterbalanced, crossover design with 20 Veterans Affairs prescribers to compare original versus redesigned alerts. We redesigned drug-allergy, drug-drug interaction, and drug-disease alerts based upon human factors principles. We assessed usability (learnability of redesign, efficiency, satisfaction, and usability errors), perceived workload, and prescribing errors. Although prescribers received no training on the design changes, prescribers were able to resolve redesigned alerts more efficiently (median (IQR): 56 (47) s) compared to the original alerts (85 (71) s; p=0.015). In addition, prescribers rated redesigned alerts significantly higher than original alerts across several dimensions of satisfaction. Redesigned alerts led to a modest but significant reduction in workload (p=0.042) and significantly reduced the number of prescribing errors per prescriber (median (range): 2 (1-5) compared to original alerts: 4 (1-7); p=0.024). Aspects of the redesigned alerts that likely contributed to better prescribing include design modifications that reduced usability-related errors, providing clinical data closer to the point of decision, and displaying alert text in a tabular format. Displaying alert text in a tabular format may help prescribers extract information quickly and thereby increase responsiveness to alerts. This simulation study provides evidence that applying human factors design principles to medication alerts can improve usability and prescribing outcomes.

Predictive performance of cardiovascular disease (CVD) risk calculators appears suboptimal in rheumatoid arthritis (RA). A disease-specific CVD risk algorithm may improve CVD risk prediction in RA. The objectives of this study are to adapt the Systematic COronary Risk Evaluation (SCORE) algorithm with determinants of CVD risk in RA and to assess the accuracy of CVD risk prediction calculated with the adapted SCORE algorithm. Data from the Nijmegen early RA inception cohort were used. The primary outcome was first CVD events. The SCORE algorithm was recalibrated by reweighing included traditional CVD risk factors and adapted by adding other potential predictors of CVD. Predictive performance of the recalibrated and adapted SCORE algorithms was assessed and the adapted SCORE was externally validated. Of the 1016 included patients with RA, 103 patients experienced a CVD event. Discriminatory ability was comparable across the original, recalibrated and adapted SCORE algorithms. The Hosmer-Lemeshow test results indicated that all three algorithms provided poor model fit (p<0.05) for the Nijmegen and external validation cohort. The adapted SCORE algorithm mainly improves CVD risk estimation in non-event cases and does not show a clear advantage in reclassifying patients with RA who develop CVD (event cases) into more appropriate risk groups. This study demonstrates for the first time that adaptations of the SCORE algorithm do not provide sufficient improvement in risk prediction of future CVD in RA to serve as an appropriate alternative to the original SCORE. Risk assessment using the original SCORE algorithm may underestimate CVD risk in patients with RA. Published by the BMJ Publishing Group Limited.

To recruit South Asian pregnant women, living in the UK, into a clinicoepidemiological study for the collection of lifestyle survey data and antenatal blood and to retain the women for the later collection of cord blood and meconium samples from their babies for biochemical analysis. A longitudinal study recruiting pregnant women of South Asian and Caucasian origin living in the UK. Recruitment of the participants, collection of clinical samples and survey data took place at the 2 sites within a single UK Northern Hospital Trust. Pregnant women of South Asian origin (study group, n=98) and of Caucasian origin (comparison group, n=38) living in Leeds, UK. Among the participants approached, 81% agreed to take part in the study while a 'direct approach' method was followed. The retention rate of the participants was a remarkable 93.4%. The main challenges in recruiting the ethnic minority participants were their cultural and religious conservativeness, language barrier, lack of interest and feeling of extra 'stress' in taking part in research. The chief investigator developed an innovative participant retention method, associated with the women's cultural and religious practices. The method proved useful in retaining the participants for about 5 months and in enabling successful collection of clinical samples from the same mother-baby pairs. The collection of clinical samples and lifestyle data exceeded the calculated sample size required to give the study sufficient power. The numbers of samples obtained were: maternal blood (n=171), cord blood (n=38), meconium (n=176), lifestyle questionnaire data (n=136) and postnatal records (n=136). Recruitment and retention of participants, according to the calculated sample size, ensured sufficient power and success for a clinicoepidemiological study. Results suggest that development of trust and confidence between the participant and the researcher is the key to the success of a clinical and epidemiological study involving ethnic minorities.

Hawaiian Volcano Observatory 1978 Annual Administrative Report

USGS Publications Warehouse

Nakata, Jennifer S.

2007-01-01

INTRODUCTORY NOTE The Hawaiian Volcano Observatory Summaries have been published in the current format since 1956. The Quarterly Summaries (1956 through 1973) and the Annual Summaries (1974 through 1985) were originally published as Administrative Reports. These reports have been compiled and published as U.S. Geological Survey Open-File Reports. The quarterly reports have been combined and published as one annual summary. All the summaries from 1956 to the present are now available as .pdf files at http://www.usgs.gov/pubprod. The earthquake summary data are presented as a listing of origin time, depth, magnitude, and other location parameters. Network instrumentation, field station sites, and location algorithms are described. Tilt and other deformation data are included until Summary 77, January to December 1977. From 1978, the seismic and deformation data are published separately, due to differing schedules of data reduction. There are eight quarters - from the fourth quarter of 1959 to the third quarter of 1961 - that were never published. Two of these (4th quarter 1959, 1st quarter 1960) have now been published, using handwritten notes of Jerry Eaton (HVO seismologist at the time) and his colleagues. The seismic records for the remaining six summaries went back to California in 1961 with Jerry Eaton. Other responsibilities intervened, and the seismic summaries were never prepared.

Research is important for the development of family medicine as a professional field in primary care. The aim of this study was to suggest directions for the development of family medicine research by analyzing research trends in original papers published in the Korean Journal of Family Medicine (KJFM) and international journals. We investigated original research papers published in KJFM and 4 international journals from August 2009 to July 2010. Analysis was conducted according to research topics, authors, methods, participants, and data sources. 'Clinical research' was the most common research topic in both the KJFM (88.3%) and international journals (57.3%); however, international journals had more studies in other domains ('education and research,' 'health service,' and 'family medicine'). More authors other than family physicians participated in international journals than in the KJFM (58% and 3.3%, respectively). Most studies were 'cross-sectional' in KJFM (77.0%) and international journals (51.5%): however, the latter had more 'qualitative' studies, 'cohort' studies, and 'systematic reviews' than the former. The largest study population was 'visitors of health promotion center' in the KJFM and 'outpatients' in international journals. Most of the study sources were 'survey' and 'medical records' in both. There were limitations of diversity in the papers of the KJFM. Future investigation on papers of other than family medicine journals should be planned to assess research trends of family physicians.

Factors influencing successful peer-reviewed publication of original research presentations from the American Society of Pediatric Otolaryngology (ASPO).

To analyze factors associated with progression of an original scientific presentation at the American Society of Pediatric Otolaryngology (ASPO) Annual Meeting to publication in a peer-reviewed journal. A dataset of presenters was created to enable prospective follow-up to assess early impressions regarding publication success with longer-term publication outcomes. Prior to the Annual ASPO meeting in 2013, a survey consisting of 10 questions was e-mailed to all 59 presenters. Questions were designed to assess presenter expectations on publication, barriers to publishing, and experience in presenting, publishing and clinical practice. A second survey was sent 12 months later to those respondents of the first survey who were amenable to follow-up. Overall, 46 of 59 (78%) presenters responded to the initial survey prior to their ASPO 2013 presentation. Of these, 34 agreed to participate in a longer-term follow-up of their presentation to publication experience. Of these 34, there were 17 who participated in the follow-up survey 1 year later. Just under half of the original respondents were residents (46%). All presenters (100%) planned to re-submit a revised manuscript if initially rejected. However, 35% of follow-up respondents did not make initial submission to a peer-reviewed journal. Results of a descriptive analysis suggest that more experienced researchers expect their submitted manuscript to be accepted for publication within a shorter time frame than those that have published fewer papers. Time was ranked as the greatest barrier to publication (60%) of those surveyed both in the initial prospective survey and for those who did not publish a paper in the follow-up survey (83%). This study suggests a strong desire and expectation of publishing ASPO presentations. Despite this expectation, past research and this data set suggest this expectation often does not materialize. "Time constraints" were the most commonly identified barrier to publication. To enhance dissemination of new findings from ASPO meetings, institutions and individuals should examine methods that facilitate and incentivize publication of findings in peer-reviewed publications.

AGU's international interdisciplinary journal Water Resources Research (WRR) publishes original contributions in hydrology; the physical, chemical, and biological sciences; and the social and policy sciences, including economics, systems analysis, sociology, and law. With the rising relevance of water economics and related social sciences, the editors of WRR continue to encourage submissions on economics and policy. WRR was originally founded in the mid 1960s by Walter Langbein and economist Allen Kneese. Several former WRR editors have been economists—including David Brookshire, Ron Cummings, and Chuck Howe—and many landmark articles in water economics have been published in WRR.

Do review articles boost journal impact factors? A longitudinal analysis for five pharmacology journals.

PubMed

Amiri, Marjan; Michel, Martin C

2018-06-21

The impact factor is a frequently applied tool in research output analytics. Based on five consecutive publication years each of five pharmacology journals, we have analyzed to which extent review articles yield more impact factor-relevant citations than original articles. Our analysis shows that review articles are quoted about twice as often as original articles published in the same year in the same journal. We conclude that inclusion of review articles does not substantially affect the impact factor of a journal unless they account for considerably more than 10% of all published articles.

Importance of being indexed in important databases--effect on the quantity of published articles in JBUON.

PubMed

Vuckovic-Dekic, Ljiljana; Gavrilovic, Dusica

2016-01-01

To investigate the dynamics of indexing the Journal of the Balkan Union of Oncology (JBUON) in important biomedical databases, the effects on the quantity and type of published articles, and also the countries of the (co)authors of these papers. The process of the JBUON indexing started with EMBASE/Excerpta Medica, followed in 2006 (PUBMED/MEDLINE) and continued every second year in other important biomedical databases, until 2012 when JBUON became Open Access Journal (for even more information please visit www.jbuon.com). Including the next two years for monitoring the effect of the last indexing, we analyzed 9 volumes consisting of 36 issues that were published from January 2006 to December 2014, with regard to the number and category of articles, the contribution of authors from Balkan and non-Balkan countries, and the (co)authorship in the published articles. In the period 2006-2014, 1165 articles of different categories were published in J BUON. The indexing progress of JBUON immediately increased the submission rate, and enlarged the number of publications, original papers in particular, in every volume of JBUON. Authors from Balkan countries contributed in 80.7% of all articles. The average number of coauthors per original article grew slowly and was higher at the end of the investigated period than at the start (6.6 and 5.8, respectively). The progressing covering of JBUON in important biomedical databases and its visibility on international level attracted the attention of a large readership, and submission rate and the number of published articles grew significantly, particularly the number of original papers. This is the most important consequence of the editorial policy which will hopefully lead to even more progress of JBUON in the near future.

Authorship and sampling practice in selected biomechanics and sports science journals.

PubMed

Knudson, Duane V

2011-06-01

In some biomedical sciences, changes in patterns of collaboration and authorship have complicated the assignment of credit and responsibility for research. It is unclear if this problem of "promiscuous coauthorship" or "hyperauthorship" (defined as six or more authors) is also apparent in the applied research disciplines within sport and exercise science. This study documented the authorship and sampling of patterns of original research reports in three applied biomechanics (Clinical Biomechanics, Journal of Applied Biomechanics, and Sports Biomechanics) and five similar subdisciplinary journals within sport and exercise science (International Journal of Sports Physiology and Performance, Journal of Sport Rehabilitation, Journal of Teaching Physical Education, Measurement in Physical Education and Exercise Sciences, and Motor Control). Original research reports from the 2009 volumes of these biomechanics and sport and exercise journals were reviewed. Single authorship of papers was rare (2.6%) in these journals, with the mean number of authors ranging from 2.7 to 4.5. Sample sizes and the ratio of sample to authors varied widely, and these variables tended not to be associated with number of authors. Original research reports published in these journals in 2009 tended to be published by small teams of collaborators, so currently there may be few problems with promiscuous coauthorship in these subdisciplines of sport and exercise science.

The representation of women in Japanese academic medicine is not evident. We aimed to assess trends related to the proportion of female first authors in Japanese cardiovascular journals.We reviewed original research articles in 6 journals published in English by Japanese societies between 2006 and 2015 related to cardiovascular fields. We conducted a multivariable logistic regression analysis to assess the factors associated with the gender of first authors and plotted the trend of predicted probability for female first authors over the study period. Of 7,005 original articles, 1,330 (19.0%) had female first authors. Affiliations located in Japan (adjusted odds ratio [aOR], 0.76; 95% confidence interval [CI], 0.71-0.81), concurrent first and corresponding authors (aOR, 0.69; 95% CI, 0.64-0.74), and the total number of listed authors (aOR, 0.97; 95% CI, 0.95-0.99) were negatively associated with female first authors. The adjusted probability of a female first author increased from 13% to 20% on an average between 2006 and 2009, but the increase reached a plateau after 2010.Female first authors of original research articles published in Japanese cardiovascular journals increased over the examined decade. However, the representation of women is still low and has plateaued in recent years. A gender gap in authorship for Japanese cardiovascular journals remains.

Introduction: Acta Informatica Medica is official journal of the Academy for Medical Sciences of Bosnia and Herzegovina (from 2014 Acta Inform Med is published bimonthly). Aim: To evaluate journal “Acta Informatica Medica” in 2015 and compare findings to previous years. Material and methods: The study has retrospective and descriptive character, and included the period 2008-2015 (included 36 issues of journal). Results: A total of 83 (average 13,8 articles per journal) articles were published in Acta Informatica Medica during 2015. Analyzing the type of articles, original articles are present in majority during 2015 (68,6%) (by analyzing last eight years, 310 (67,3%) were original). During 2015, 27,7% of articles were related to the applied of Health informatics in field of clinical medicine, 63,8% preclinical medicine and 8,5% to public health. Collaboration rate in 2015 was 0,84. Most often the time required for decision on acceptance of article in 2015 is between 50 and 60 days. Articles came from 16 countries. According to scimagojr.com for 2014, Acta Informatica Medica has SCImago Journal Rank 0,166, while Cites / Doc. (2 years) parameter (widely used as impact index) is 0,70. According to GoogleScholar, h5 index is 11 and h5 median is 19. We analyzed the Acta Informatica Medica by “Publish or Perish” software - H index was 14, g index was 19 and e-index was 10.39. Conclusion: Year after year the highest number of original articles are published. Although the period of revision of articles is acceptable, the period up to two months is certainly not long, the goal is to reduce this period. Although the magazine in mentioned field found its place, although it is indexed in numerous bases, including: PubMed, PubMed Central, SCOPUS, EMBASE, EBSCO, etc. The main goal for next year is that the magazine becomes part of the Web of Science. Imperative is further internationalization of the magazine. PMID:27147796

We report the case of a 14-year-old girl with mental retardation and dysmorphic features referred to child psychiatry because of altered behavior at school. Karyotyping (GTG banding), in situ fluorescent hybridization (FISH) and molecular study of parental origin by polymorphic STS were performed. Genetic study revealed a 48,XXXX karyotype with a maternal origin of the X-tetrasomy. The mechanism was successive non-dysjunction at meiosis I and II. The interest of this case lies in the rarity of the chromosomal anomaly and its late diagnosis, leading to a failure to adapt the girl's education to her needs, with consequences for her psyche.

In order to be comprehensible and comparable scientific data should be reported according to a certain standard. One example is the 'STAndards for Reporting of Diagnostic Accuracy (STARD) Statement', a 25-item checklist for the appropriate conduct and reporting of diagnostic studies. Usually such scientific standards are published in English. The International Society for Pharmacoeconomics and Outcome Research (ISPOR) has developed guidelines for the translation and cultural adaptation of written medical instruments. The aim was to apply these ISPOR criteria to the German translation of the STARD Statement in order to allow for authorisation to be conferred by the original authors. In cooperation with the original authors the STARD statement was translated according to the ISPOR steps: (1) Preparation, (2) Forward Translation, (3) Reconciliation, (4) Back Translation, (5) Back Translation Review, (6) Harmonisation, (7) Cognitive Debriefing, which evaluated comprehensiveness and linguistic style with marks from 1 (very good) to 6 (insufficient), and (8) Review of Cognitive Debriefing Results and Finalisation. Die ISPOR criteria applied reasonably to the translation process, which required the work input and energy of four scientists and one professional translator and 177 accumulated working hours. The cognitive debriefing resulted in average grades 1.62±0.33 and 1.72±0.39 for comprehensiveness and linguistic style, respectively. Finally, the German STARD version was authorised by the original authors. Die ISPOR guidelines seem to be a suitable means to facilitate the structured adaptation of defined criteria for the reporting of studies, such as the STARD statement, to other languages.

Dhat syndrome is a widely recognized clinical condition often seen on the Indian subcontinent that is characterized by a preoccupation with semen loss in urine and other symptoms such as fatigue or depressed mood. Although it has been considered to be a culture-bound syndrome, it may also be regarded as a distinct manifestation of depression or another medical illness. The purpose of this paper was to carry out a systematic review on Dhat syndrome. A review of the literature published up until February 2012 was conducted using the key words [Dhat syndrome] or [semen-loss anxiety] or [semen-loss syndrome]. We included only original studies. The majority of studies reported patients from the Indian subcontinent. There was a high degree of heterogeneity among the studies. Dhat was a common condition in young people from certain cultures and origins. Depressive and anxiety symptoms were common, including fatigue, sleepiness, and sexual dysfunction. Good clinical engagement, social support, and sexual education were useful in some cases. Given the high rate of comorbid depressive symptoms, antidepressant has been used. In an increasingly globalized world, clinicians must be able to properly diagnose and treat patients from other cultures, who may report symptoms that are influenced by their beliefs, culture, or place of origin. Dhat may be a common manifestation of a depressive or anxiety disorder in certain cultures. Further research is needed to improve our understanding of this condition, to clarify its nosologic status, and to offer appropriate treatment to affected individuals.

This paper introduced the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2), including the development and comparison with the original QUADAS, and illustrated the application of QUADAS-2 in a published paper related to the study on diagnostic accuracy which was included in systematic review and Meta-analysis. QUADAS-2 presented considerable improvement over the original tool. Confused items that included in QUADAS had disappeared and the quality assessment of the original study replaced by the rating of risk on bias and applicability. This was implemented through the description on the four main domains with minimal overlapping and answering the signal questions in each domain. The risk of bias and applicability with 'high','low' or 'unclear' was in line with the risk of bias assessment of intervention studies in Cochrane, so to replace the total score of quality assessment in QUADAS. Meanwhile, QUADAS-2 was also applicable to assess the diagnostic accuracy studies in which follow-up without prognosis was involved in golden standard. It was useful to assess the overall methodological quality of the study despite more time consuming than the original QUADAS. However, QUADAS-2 needs to be modified to apply in comparative studies on diagnostic accuracy and we hope the users would follow the updates and give their feedbacks on line.

To develop and validate equations to estimate the percentage of body fat of children and adolescents from Mexico using anthropometric measurements. A cross-sectional study was carried out with 601 children and adolescents from Mexico aged 5-19 years. The participants were randomly divided into the following two groups: the development sample (n=398) and the validation sample (n=203). The validity of previously published equations (e.g., Slaughter) was also assessed. The percentage of body fat was estimated by dual-energy X-ray absorptiometry. The anthropometric measurements included height, sitting height, weight, waist and arm circumferences, skinfolds (triceps, biceps, subscapular, supra-iliac, and calf), and elbow and bitrochanteric breadth. Linear regression models were estimated with the percentage of body fat as the dependent variable and the anthropometric measurements as the independent variables. Equations were created based on combinations of six to nine anthropometric variables and had coefficients of determination (r 2 ) equal to or higher than 92.4% for boys and 85.8% for girls. In the validation sample, the developed equations had high r 2 values (≥85.6% in boys and ≥78.1% in girls) in all age groups, low standard errors (SE≤3.05% in boys and ≤3.52% in girls), and the intercepts were not different from the origin (p>0.050). Using the previously published equations, the coefficients of determination were lower, and/or the intercepts were different from the origin. The equations developed in this study can be used to assess the percentage of body fat of Mexican schoolchildren and adolescents, as they demonstrate greater validity and lower error compared with previously published equations.

Bibliometric analysis of oral and maxillofacial cytology-related articles published in a cytology journal from India

PubMed Central

Shamim, Thorakkal

2018-01-01

Background: There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. Objective: This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Materials and Methods: Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Results: Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). Conclusion: This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India. PMID:29731569

To analyse the institutionalisation of nutrition sciences in Spain in the second half of the twentieth century, and evaluate the activities of the journal Anales de Bromatología. Descriptive bibliometric study of the original articles. Full names of the authors and the complete article title were recorded. Using key words, each article was assigned by consensus of the researchers to a single main subject in accordance with the thirteen subject areas addressed by the Spanish Society of Bromatology in its meetings. An analysis was conducted of the distribution and trends of general productivity indicators and their characteristics. A total of 917 original articles were published, with a mean of 20.8 papers/year. The subjects for which the highest percentage of articles was recorded were foreign substances in foods, foods of plant origin and nutrition. A total of 874 authors contributed, with a collaboration rate of 2.43 and a transience rate of 70.1%. Distribution of the number of authors per article was close to that indicated by Lotka's law of scientific productivity. The top twelve producers, predominantly women, participated in 49.9% of the articles published. The journal showed low productivity and was of an endogamous nature, with a predominance of authors related to the School of Bromatology in the Faculty of Pharmacy, at the Complutense University. The subjects addressed reflected the demands of the nutrition transition in Spain.

2014-03-01

The number of citations that a published article has received reflects the importance of the paper in the particular area of practice. In microsurgery, thus far, which journal articles are cited most frequently is unknown. The purpose of this study was to identify and analyze the characteristics of the top 50 papers in the field of microsurgery in the plastic surgery literature. The 50 most cited papers published in high impact plastic surgery and microsurgery journals were identified. The articles were ranked in the order of the number of citations received. These 50 classic papers were analyzed for article type, journal distribution, and geographic and institutional origin. Six international journals contributed to the top 50 papers in microsurgery. The most cited paper reported on the early use of the vascularized bone graft and was cited 116 times. The top 50 papers originated from just 10 countries with the United States producing the most. The Preston and Northcote Community Hospital, Melbourne published 5 papers and this was the most productive institution in the top 50. These papers represent many important milestones in the relatively short history of microsurgery. Furthermore, our citation analysis provides useful information to budding authors as to what makes a paper attain a "classic" status.

Acute lower gastrointestinal system (GIS) bleeding is a life-threatening condition. Immediate determination of the origin of the bleeding is crucial, since hemostatic management must be initiated as rapidly as possible. Colonoscopy, radionuclide studies, and conventional angiography are considered the most important methods for assessing the origin of the bleeding. There are few published reports about the feasibility of computed tomography (CT) in acute GIS bleeding. We present multidetector CT (MDCT) findings in a case of Hodgkin disease status one month post-chemotherapy (CHOP protocol; cyclophosphamide, doxorubicin, vincristine, prednisone) that presented with acute lower GIS bleeding.

Defibrotide is a single-stranded nucleic acid polymer originally derived from porcine mucosa. Cheap salmon sperm DNA is commercially available and widely used in drug production. In this study, oligodeoxyribonucleotides were successfully obtained from the controlled depolymerization of salmon sperm DNA. The obtained product shared similar chemical and biological properties with defibrotide produced by Gentium SpA, Italy. It was also found that oligodeoxyribonucleotides derived from non-mammalian origins could also directly stimulate tissue plasminogen activator (t-PA) release from cultured human endothelial cells, and enhance fibrinolytic activity in the rabbit.

Young, Rachel; Willis, Erin; Stemmle, John; Rodgers, Shelly

2015-07-01

Newspaper health stories often originate with news releases from health organizations. Tailoring news releases to a particular mass media outlet increases the possibility that the release will result in a published story. This study describes a 2-year effort to promote coverage of health through dissemination of localized health news releases to newspapers. Each newspaper received stories tailored to that community. Localized elements of stories included local headlines and local data. Nearly half of newspapers in our study (48.2%) published at least one of our health news stories, and 541 health news stories were published as a result of the project. We also examined which types of newspapers were most likely to publish health news stories. Newspapers in rural versus suburban and urban areas were more likely to publish health news stories, as were midsized newspapers. In addition, rural newspapers were more likely than urban newspapers to publish stories about aging, specifically arthritis and heart disease. Our findings indicate that tailoring health news releases with local information and targeting releases to align with newspaper audience demographics could increase the quantity and quality of health-promoting information available to rural residents, who experience disparities in health care access and health outcomes. © 2015 Society for Public Health Education.

Cross-cultural adaptation and translation of a quality of life tool for new mothers: a methodological and experiential account from six countries.

To examine the challenges and solutions encountered in the translation and cross-cultural adaptation of an English language quality of life tool in India, China, Iran, Portugal, Brazil, and Poland. Those embarking on research involving translation and cross-cultural adaptation must address certain practical and conceptual issues. These include instrument choice, linguistic factors, and cultural or philosophical differences, which may render an instrument inappropriate, even when expertly translated. Publication bias arises when studies encountering difficulties do not admit to these, or are not published at all. As an educative guide to the potential pitfalls involved in the cross-cultural adaptation process, this article reports the conceptual, linguistic, and methodological experiences of researchers in six countries, who translated and adapted the Mother-Generated Index, a quality of life tool originally developed in English. Principal investigator experience from six stand-alone studies (two published) ranging from postgraduate research to citywide surveys. DISCUSSION/IMPLICATIONS FOR NURSING: This analysis of a series of stand-alone cross-cultural studies provides lessons about how conceptual issues, such as the uniqueness of perceived quality of life and the experience of new motherhood, can be addressed. This original international approach highlights practical lessons relating to instrument choice, and the resources available to researchers with different levels of experience. Although researchers may be confident of effective translation, conceptual and practical difficulties may be more problematic. Instrument choice is crucial. Researchers must negotiate adequate resources for cross-cultural research, including time, translation facilities, and expert advice about conceptual issues. © 2012 Blackwell Publishing Ltd.

A meta-analysis is a statistical and analytical method which combines and synthesizes different independent studies and integrates their results into one common result. Analysis of the journals "Medical Archives", "Materia Socio Medica" and "Acta Informatica Medica", which are located in the most eminent indexed databases of the biomedical milieu. The study has retrospective and descriptive character, and included the period of the calendar year 2014. Study included six editions of all three journals (total of 18 journals). In this period was published a total of 291 articles (in the "Medical Archives" 110, "Materia Socio Medica" 97, and in "Acta Informatica Medica" 84). The largest number of articles was original articles. Small numbers have been published as professional, review articles and case reports. Clinical events were most common in the first two journals, while in the journal "Acta Informatica Medica" belonged to the field of medical informatics, as part of pre-clinical medical disciplines. Articles are usually required period of fifty to fifty nine days for review. Articles were received from four continents, mostly from Europe. The authors are most often from the territory of Bosnia and Herzegovina, then Iran, Kosovo and Macedonia. The number of articles published each year is increasing, with greater participation of authors from different continents and abroad. Clinical medical disciplines are the most common, with the broader spectrum of topics and with a growing number of original articles. Greater support of the wider scientific community is needed for further development of all three of the aforementioned journals.

A major limitation when reconstructing the origin and evolution of HPV-16 is the lack of reliable substitution rate estimates for the viral genes. On the basis of the hypothesis of human HPV-16 co-divergence, we estimated a mean evolutionary rate of 1.47×10(-7) (95% HPD=0.64-2.47×10(-7)) subs/site/year for the viral LCR region. The results of a Bayesian phylogeographical analysis suggest that the currently circulating HPV-16 most probably originated in Africa about 110 thousand years ago (Kya), before giving rise to four known geographical lineages: the Asian/European lineage, which most probably originated in Asia a mean 38 Kya, and the Asian/American and two African lineages, which probably respectively originated about 33 and 27 Kya. These data closely reflect current hypotheses concerning modern human expansion based on studies of mitochondrial DNA phylogeny. The correlation between ancient human migration and the present HPV phylogeny may be explained by the co-existence of modes of transmission other than sexual transmission. Copyright © 2016.

Umaña-Taylor, Adriana J; Wong, Jessie J; Gonzales, Nancy A; Dumka, Larry E

2012-08-01

Existing work has identified perceived discrimination as a risk factor that may contribute to the relatively poorer academic outcomes exhibited by Mexican-origin adolescents in the U.S. The current study examined the longitudinal associations among perceived discrimination and three indices of adolescent adjustment in the school setting (i.e., grade point average, teacher reports of externalizing, adolescents' deviant peer associations) among 178 Mexican-origin adolescents (53% female). Ethnic identity affirmation was examined as a protective factor expected to reduce the negative effects of discrimination on adolescents' adjustment, and gender was examined as a potential moderator of the associations of interest. Findings indicated that the deleterious effects of discrimination on adolescents' adjustment in school were particularly salient for Mexican-origin male adolescents. Importantly, ethnic identity affirmation emerged as a protective factor for Mexican-origin male adolescents by buffering the negative effects of discrimination on their externalizing behaviors in school.

Recombinant human growth hormone (rhGH) is the first biosimilar drug approved by the European Medicines Agency in 2006, using the biosimilar registration process. It was authorised for the treatment of growth hormone deficiency, and growth disorders associated with Turner's syndrome, chronic renal failure, Prader-Willi syndrome, and growth disorders in children/adolescents born small for gestational age, and replacement therapy in adults with pronounced growth hormone deficiency. This review is focused on the scientific evidence published about this drug in the last ten years, including the clinical trials on which the approval of the regulatory authority is based, and the most relevant studies evaluating the clinical impact of the drug in clinical practice. The equivalence between biosimilar and original product has been confirmed in the clinical trials published by Romer et al. and López-Siguero et al. Furthermore, studies carried out in real-life conditions confirm its long-term efficacy and safety, as well as the absence of clinical impact by switching treatment from the original to the biosimilar product. The number of patients receiving this medication has continuously increased since its approval. Its equivalence with the original product has been verified. Preliminary data from the post-authorisation PATRO study confirm the efficacy and safety of the biosimilar product in comparison with data from clinical trials. However, final results must be evaluated at the end of the study, which will provide additional information about the long-term efficacy and safety of the biosimilar drug.

Emergency admission is associated with the potential for adverse events in older people and risk prediction models are available to identify those at highest risk of admission. The aim of this study was to externally validate and compare the performance of the Probability of repeated admission (Pra) risk model and a modified version (incorporating a multimorbidity measure) in predicting emergency admission in older community-dwelling people. 15 general practices (GPs) in the Republic of Ireland. n=862, ≥70 years, community-dwelling people prospectively followed up for 2 years (2010-2012). Pra risk model (original and modified) calculated for baseline year where ≥0.5 denoted high risk (patient questionnaire, GP medical record review) of future emergency admission. Emergency admission over 1 year (GP medical record review). descriptive statistics, model discrimination (c-statistic) and calibration (Hosmer-Lemeshow statistic). Of 862 patients, a total of 154 (18%) had ≥1 emergency admission(s) in the follow-up year. 63 patients (7%) were classified as high risk by the original Pra and of these 26 (41%) were admitted. The modified Pra classified 391 (45%) patients as high risk and 103 (26%) were subsequently admitted. Both models demonstrated only poor discrimination (original Pra: c-statistic 0.65 (95% CI 0.61 to 0.70); modified Pra: c-statistic 0.67 (95% CI 0.62 to 0.72)). When categorised according to risk-category model, specificity was highest for the original Pra at cut-point of ≥0.5 denoting high risk (95%), and for the modified Pra at cut-point of ≥0.7 (95%). Both models overestimated the number of admissions across all risk strata. While the original Pra model demonstrated poor discrimination, model specificity was high and a small number of patients identified as high risk. Future validation studies should examine higher cut-points denoting high risk for the modified Pra, which has practical advantages in terms of application in GP. The original Pra tool may have a role in identifying higher-risk community-dwelling older people for inclusion in future trials aiming to reduce emergency admissions.

Recent decades have seen rapid development of new analytical methods to investigate patterns of interspecific variation. Yet these cutting-edge statistical analyses often rely on data of questionable origin, varying accuracy, and weak comparability, which seem to have reduced the reproducibility of studies. It is time to improve the transparency of comparative data while also making these improved data more widely available. We, the authors, met to discuss how transparency, usability, and reproducibility of comparative data can best be achieved. We propose four guiding principles: 1) data identification with explicit operational definitions and complete descriptions of methods; 2) inclusion of metadata that capture key characteristics of the data, such as sample size, geographic coordinates, and nutrient availability (for example, captive versus wild animals); 3) documentation of the original reference for each datum; and 4) facilitation of effective interactions with the data via user friendly and transparent interfaces. We urge reviewers, editors, publishers, database developers and users, funding agencies, researchers publishing their primary data, and those performing comparative analyses to embrace these standards to increase the transparency, usability, and reproducibility of comparative studies. © 2016 Wiley Periodicals, Inc.

Abstract Scholarly publishing and citation practices have developed largely in the absence of versioned documents. The digital age requires new practices to combine the old and the new. We describe how the original published source and a versioned wiki page based on it can be reconciled and combined into a single citation reference. We illustrate the citation mechanism by way of practical examples focusing on journal and wiki publishing of taxon treatments. Specifically, we discuss mechanisms for permanent cross-linking between the static original publication and the dynamic, versioned wiki, as well as for automated export of journal content to the wiki, to reduce the workload on authors, for combining the journal and the wiki citation and for integrating it with the attribution of wiki contributors.

Castration-Resistant Prostate Cancer: AUA Guideline Amendment 2015.

PubMed

Lowrance, William T; Roth, Bruce J; Kirkby, Erin; Murad, Mohammad Hassan; Cookson, Michael S

2016-05-01

The purpose of this amendment is to incorporate relevant newly-published literature to better provide a rational basis for the management of patients with castration-resistant prostate cancer. The original systematic review and meta-analysis of the published literature yielded 303 studies published from 1996 through 2013. This review informed the majority of the guideline statements. Clinical Principles and Expert Opinions were used for guideline statements lacking sufficient evidence. In April 2014, the CRPC guideline underwent amendment based on an additional literature search, which retrieved additional studies published between February 2013 and February 2014. Thirty-seven studies from this search provided data relevant to the specific treatment modalities for CRPC. In March 2015, the CRPC guideline underwent a second amendment, which incorporated 10 additional studies into the evidence base published through February 2015. Guideline statements based on six index patients developed to represent the most common scenarios encountered in clinical practice were amended appropriately. The additional literature provided the basis for an update of current supporting text as well as the incorporation of new guideline statements for multiple index patients. Given the rapidly evolving nature of this field, this guideline should be used in conjunction with recent systematic literature reviews and an understanding of the individual patient's treatment goals. Patients' preferences and personal goals should be considered when choosing management strategies. This guideline will be continually updated as new literature emerges in the field.

Translating experimental findings into clinically effective therapies is one of the major bottlenecks of modern medicine. As this has been particularly true for cerebrovascular research, attention has turned to the quality and validity of experimental cerebrovascular studies. We set out to assess the study design, statistical analyses, and reporting of cerebrovascular research. We assessed all original articles published in the Journal of Cerebral Blood Flow and Metabolism during the year 2008 against a checklist designed to capture the key attributes relating to study design, statistical analyses, and reporting. A total of 156 original publications were included (animal, in vitro, human). Few studies reported a primary research hypothesis, statement of purpose, or measures to safeguard internal validity (such as randomization, blinding, exclusion or inclusion criteria). Many studies lacked sufficient information regarding methods and results to form a reasonable judgment about their validity. In nearly 20% of studies, statistical tests were either not appropriate or information to allow assessment of appropriateness was lacking. This study identifies a number of factors that should be addressed if the quality of research in basic and translational biomedicine is to be improved. We support the widespread implementation of the ARRIVE (Animal Research Reporting In Vivo Experiments) statement for the reporting of experimental studies in biomedicine, for improving training in proper study design and analysis, and that reviewers and editors adopt a more constructively critical approach in the assessment of manuscripts for publication.

Taxonomic descriptions are traditionally composed in natural language and published in a format that cannot be directly used by computers. The Exploring Taxon Concepts (ETC) project has been developing a set of web-based software tools that convert morphological descriptions published in telegraphic style to character data that can be reused and repurposed. This paper introduces the first semi-automated pipeline, to our knowledge, that converts morphological descriptions into taxon-character matrices to support systematics and evolutionary biology research. We then demonstrate and evaluate the use of the ETC Input Creation - Text Capture - Matrix Generation pipeline to generate body part measurement matrices from a set of 188 spider morphological descriptions and report the findings. From the given set of spider taxonomic publications, two versions of input (original and normalized) were generated and used by the ETC Text Capture and ETC Matrix Generation tools. The tools produced two corresponding spider body part measurement matrices, and the matrix from the normalized input was found to be much more similar to a gold standard matrix hand-curated by the scientist co-authors. Special conventions utilized in the original descriptions (e.g., the omission of measurement units) were attributed to the lower performance of using the original input. The results show that simple normalization of the description text greatly increased the quality of the machine-generated matrix and reduced edit effort. The machine-generated matrix also helped identify issues in the gold standard matrix. ETC Text Capture and ETC Matrix Generation are low-barrier and effective tools for extracting measurement values from spider taxonomic descriptions and are more effective when the descriptions are self-contained. Special conventions that make the description text less self-contained challenge automated extraction of data from biodiversity descriptions and hinder the automated reuse of the published knowledge. The tools will be updated to support new requirements revealed in this case study.

A 5-Year Review of Clinical Outcome Measures Published in the Journal of the American Podiatric Medical Association and the Journal of Foot and Ankle Surgery®.

Hasenstein, Todd; Greene, Timothy; Meyr, Andrew J

This investigation presents a review of all of the clinical outcome measures used by authors and published in the Journal of the American Podiatric Medical Association and the Journal of Foot and Ankle Surgery ® from January 1, 2011, to December 31, 2015. Of 1,336 articles published during this time frame, 655 (49.0%) were classified as original research and included in this analysis. Of these 655 articles, 151 (23.1%) included at least one clinical outcome measure. Thirty-seven unique clinical outcome scales were used by authors and published during this period. The most frequently reported scales in the 151 included articles were the American Orthopaedic Foot and Ankle Society scales (54.3%; n = 82), visual analog scale (35.8%; n = 54), Medical Outcomes Study Short Form Health Survey (any version) (10.6%; n = 16), Foot Function Index (5.3%; n = 8), Maryland Foot Score (4.0%; n = 6), and Olerud and Molander scoring system (4.0%; n = 6). Twenty-four (15.9%) articles used some form of original/subjective measure of patient satisfaction/expectation. The results of this investigation detail the considerable variety of clinical outcome measurement tools used by authors in the Journal of the American Podiatric Medical Association and the Journal of Foot and Ankle Surgery ® and might support the need for a shift toward the consistent use of a smaller number of valid, reliable, and clinically useful scales in the podiatric medical literature.

2016-04-15

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.

Changing Authorship Patterns and Publishing Habits in the European Journal of Pediatric Surgery: A 10-Year Analysis.

Pintér, András

2015-08-01

The aim of this study is an analysis of the changing authorship patterns and publishing habits encountered in papers published in the European Journal of Pediatric Surgery (EJPS) over the past 10 years. Furthermore, it seeks to anticipate the trends in the years ahead. We conducted a retrospective review of articles published in the EJPS during a 10-year period (January 1, 2003-December 31, 2012). Each article was classified as an Original Report/Original Article (OR/OA) or as a Case Report/Case Gallery (CR/CG), and they were analyzed separately. For investigation of the percentage distribution of publications according to the number of authors per articles, papers were combined and into three groups (1-2, 3-5, and 6 ≤ authors). The analysis focused on whether the work was done by members of one institution, or in collaboration with other units of the same institution, or in collaboration with other national or multinational institutes. In the past 10 years, the EJPS published 996 articles (616 ORs/OAs, 380 CRs/CGs). The one and two authored publications (125) have not decreased, the three to five authored articles (552) changed minimally, whereas the number of 6 ≤ authored publications (319) has increased. Of 996 publications, 348 were from single institutes and 648 were written in collaboration with two or more other institutes. In addition, in this 10-year period, the number of multinational articles has increased significantly from 24 to 59. Increase in cooperation within and between institutions is a positive trend, aiming with the goal of improving quality of publications. Georg Thieme Verlag KG Stuttgart · New York.

Geographic traceability is an important issue for food quality and safety control of seafood. In this study,δ 13 C and δ 15 N values, as well as fatty acid (FA) content of 133 samples of A. japonicus from seven sampling points in northern China Sea were determined to evaluate their applicability in the origin traceability of A. japonicus. Principal component analysis (PCA) and discriminant analysis (DA) were applied to different data sets in order to evaluate their performance in terms of classification or predictive ability. δ 13 C and δ 15 N values could effectively discriminate between different origins of A. japonicus. Significant differences in the FA compositions showed the effectiveness of FA composition as a tool for distinguishing between different origins of A. japonicus. The two technologies, combined with multivariate statistical analysis, can be promising methods to discriminate A. japonicus from different geographical areas. Copyright © 2016.

Social influence and mental routes to the production of authentic false memories and inauthentic false memories.

PubMed

Wagner, Michael F; Skowronski, John J

2017-05-01

Two studies assessed the extent to which people incorporated false facts provided by bogus others into their own recognition memory reports, and how these false memory reports were affected by: (a) truth of the information in others' summaries supporting the false facts, (b) motivation to process stories and summaries, (c) source credibility, and (d) ease of remembering original facts. False memory report frequency increased when false facts in a summary were supported by true information and varied inversely with the ease with which original facts could be remembered. Results from a measure probing participants' memory perceptions suggest that some false memories are authentic: People sometimes lack awareness of both the incorporation of false facts into their memory reports and where the false facts came from. However, many false memories are inauthentic: Despite reporting a false memory, people sometimes retain knowledge of the original stimulus and/or the origin of false facts. Copyright © 2017.

At present, the geographical origin of extra virgin olive oils can be ensured by documented traceability, although chemical analysis may add information that is useful for possible confirmation. This preliminary study investigated the effectiveness of flash gas chromatography electronic nose and multivariate data analysis to perform rapid screening of commercial extra virgin olive oils characterized by a different geographical origin declared in the label. A comparison with solid phase micro extraction coupled to gas chromatography mass spectrometry was also performed. The new method is suitable to verify the geographic origin of extra virgin olive oils based on principal components analysis and discriminant analysis applied to the volatile profile of the headspace as a fingerprint. The selected variables were suitable in discriminating between "100% Italian" and "non-100% Italian" oils. Partial least squares discriminant analysis also allowed prediction of the degree of membership of unknown samples to the classes examined. Copyright © 2016. Published by Elsevier Ltd.

Use of bipolar radiofrequency catheter ablation in treatment of cardiac arrhythmias.

PubMed

Soucek, Filip; Starek, Zdenek

2018-05-23

Background Arrhythmia management is a complex process involving both pharmacological and non-pharmacological approaches. Radiofrequency ablation is the pillar of non-pharmacological arrhythmia treatment. Unipolar ablation is considered to be the gold standard in the treatment of the majority of arrhythmias; however, its efficacy is limited to specific cases. In particular, the creation of deep or transmural lesions to eliminate intramurally originating arrhythmias remains inadequate. Bipolar ablation is proposed as an alternative to overcome unipolar ablation boundaries. Results Despite promising results gained from in vitro and animal studies showing that bipolar ablation is superior in creating transmural lesions, the use of bipolar ablation in daily clinical practice is limited. Several studies have been published showing that bipolar ablation is effective in the treatment of clinical arrhythmias after failed unipolar ablation, however there is inconsistency regarding safety of bipolar ablation within the available research papers. According to research evidence the most common indications for bipolar ablation use are ventricular originating rhythmic disorders in patients with structural heart disease resistant to standard radiofrequency ablation. Conclusions To allow wider clinical application the efficiency and safety of bipolar ablation need to be verified in future studies.

Mitochondria are eukaryotic organelles which contain the own genetic material and evolved from free-living Eubacteria, namely hydrogen-producing Alphaproteobacteria. Since 1965, biologists provided, by research at molecular level, evidence for the prokaryotic origins of mitochondria. However, determining the precise origins of mitochondria is challenging due to inherent difficulties in phylogenetically reconstructing ancient evolutionary events. The use of new tools to evidence the prokaryotic origin of mitochondria could be useful to gain an insight into the bacterial endosymbiotic event that resulted in the permanent acquisition of bacteria, from the ancestral cell, that through time were transformed into mitochondria. Electron microscopy has shown that both proteobacterial and yeast cells during their growth in the presence of increasing amount of tellurite resulted in dose-dependent blackening of the culture due to elemental tellurium (Te(0)) that formed large deposits either along the proteobacterial membrane or along the yeast cell wall and mitochondria. Since the mitochondrial inner membrane composition is similar to that of proteobacterial membrane, in the present work we evidenced the black tellurium deposits on both, cell wall and mitochondria of ρ(+) and respiratory deficient ρ(-) mutants of yeast. A possible role of tellurite in studying the evolutionary origins of mitochondria will be discussed. Copyright © 2015. Published by Elsevier B.V.

INTRODUCTION: The present study was motivated by the need to systematically assess the research productivity of the Heart Institute (InCor), Medical School of the University of São Paulo, Brazil. OBJECTIVE: To explore methodology for the assessment of institutional scientific research productivity. MATERIALS AND METHODS: Bibliometric indicators based on searches for author affiliation of original scientific articles or reviews published in journals indexed in the databases Web of Science, MEDLINE, EMBASE, LILACS and SciELO from January 2000 to December 2003 were used in this study. The retrieved records were analyzed according to the index parameters of the journals and modes of access. The number of citations was used to calculate the institutional impact factor. RESULTS: Out of 1253 records retrieved from the five databases, 604 original articles and reviews were analyzed; of these, 246 (41%) articles were published in national journals and 221 (90%) of those were in journals with free online access through SciELO or their own websites. Of the 358 articles published in international journals, 333 (93%) had controlled online access and 223 (67%) were available through the Capes Portal of Journals. The average impact of each article for InCor was 2.224 in the period studied. CONCLUSION: A simple and practical methodology to evaluate the scientific production of health research institutions includes searches in the LILACS database for national journals and in MEDLINE and the Web of Science for international journals. The institutional impact factor of articles indexed in the Web of Science may serve as a measure by which to assess and review the scientific productivity of a research institution. PMID:19578662

Introduction Metabolic syndrome is an important public health target because of its high prevalence worldwide. Work-related psychosocial factors have been identified as determinants of metabolic syndrome components. However, there have been no systematic reviews or meta-analyses conducted to evaluate the relationship between work-related psychosocial factors and metabolic syndrome as an aggregated cluster. The aim of this study is to examine this association from published prospective studies. Methods and analysis The systematic review and meta-analysis will be conducted using published studies that will be identified from electronic databases (ie, PubMed, EMBASE, PsycINFO, PsycARTICLES and Japan Medical Abstracts Society). Studies that (1) examined the association between work-related psychosocial factors and the onset of metabolic syndrome, (2) had a longitudinal or prospective cohort design, (3) were conducted among workers, (4) provided sufficient data for calculating ORs or relative risk with a 95% CI, (5) were published as original articles written in English or Japanese, and (6) having been published until the end of 2016 will be included. Study selection, data collection, quality assessment and statistical syntheses will be conducted based on discussions among investigators. Ethics and dissemination Ethics approval was not required for this study because it was based on published studies. The results and findings of this study will be submitted and published in a scientific peer-reviewed journal. The findings from this study could be useful for assessing metabolic syndrome risk factors in the workplace, and determining approaches for prevention of metabolic syndrome in the future.

Synthesizing Risk from Summary Evidence Across Multiple Risk Factors.

PubMed

Shrier, Ian; Colditz, Graham A; Steele, Russell J

2018-07-01

Although meta-analyses provide summary effect estimates that help advise patient care, patients often want to compare their overall health to the general population. The Harvard Cancer Risk Index was published in 2004 and uses risk ratio estimates and prevalence estimates from original studies across many risk factors to provide an answer to this question. However, the published version of the formula only uses dichotomous risk factors and its derivation was not provided. The objective of this brief report was to provide the derivation of a more general form of the equation that allows the incorporation of risk factors with three or more levels.

In this study, we aimed to compare the quantity and quality of publications in health care sciences and services journals from the Chinese mainland, Taiwan, Japan, and India. Journals in this category of the Science Citation Index Expanded were included in the study. Scientific papers were retrieved from the Web of Science online database. Quality was measured according to impact factor, citation of articles, number of articles published in top 10 journals, and the 10 most popular journals by country (area). In the field of health care sciences and services, the annual incremental rates of scientific articles published from 2007 to 2014 were higher than rates of published scientific articles in all fields. Researchers from the Chinese mainland published the most original articles and reviews and had the highest accumulated impact factors, highest total article citations, and highest average citation. Publications from India had the highest average impact factor. In the field of health care sciences and services, China has made remarkable progress during the past eight years in the annual number and percentage of scientific publications. Yet, there is room for improvement in the quantity and quality of such articles. PMID:26712774

Quality was measured according to impact factor, citation of articles, number of articles published in top 10 journals, and the 10 most popular journals by country (area). In the field of health care sciences and services, the annual incremental rates of scientific articles published from 2007 to 2014 were higher than rates of published scientific articles in all fields. Researchers from the Chinese mainland published the most original articles and reviews and had the highest accumulated impact factors, highest total article citations, and highest average citation. Publications from India had the highest average impact factor. In the field of health care sciences and services, China has made remarkable progress during the past eight years in the annual number and percentage of scientific publications. Yet, there is room for improvement in the quantity and quality of such articles.

In a recent paper published in The Auk, Smith et al. (2009) raised serious concerns over an apparent lack of reproducibility in their study of stable hydrogen isotope values (δDf ) in raptor feathers. The authors based their concerns on results obtained from different laboratories to which they submitted original and blind “repeats” over a multiyear period. A regression of the original sample δD versus “repeat” measurements showed an increase in the magnitude of residuals with increasing δDf , especially for values greater than about −80‰ (Smith et al. 2009: fig. 2). Because of this, the authors “caution against the continued use of δDf for predicting geographic origin, and for addressing important conservation questions” (p. 41) and conclude that “it is counterproductive to move forward [with hydrogen isotopes in avian studies] without first establishing full confidence in the technique that underlies such insights and conservation recommendations” (p. 45). We disagree with these sentiments.

This qualitative research study, a replication of a study published in 2002, investigated the qualities of a good nurse and the role ethics plays in decision making. After reviewing the limitations of the published work, the current study implemented modifications related to the research questions, sample selection, data collection, and use of software for data analysis. The original study identified seven categories that related to being a good nurse and doing the right thing. In the present study, the use of relational analysis led to the recognition of four categories: (1) personal traits and attributes; (2) technical skills and management of care; (3) work environment and co-workers; and (4) caring and caring behaviors. To understand what it means to be a good nurse and do the right thing is a complex task; however, this research adds to the small amount of empirical data that exists to describe those characteristics.

Antimalarial resistance is rapidly spreading across parts of southeast Asia where dihydroartemisinin-piperaquine is used as first-line treatment for Plasmodium falciparum malaria. The first published reports about resistance to antimalarial drugs came from western Cambodia in 2013. Here, we analyse genetic changes in the P falciparum population of western Cambodia in the 6 years before those reports. We analysed genome sequence data on 1492 P falciparum samples from 11 locations across southeast Asia, including 464 samples collected in western Cambodia between 2007 and 2013. Different epidemiological origins of resistance were identified by haplotypic analysis of the kelch13 artemisinin resistance locus and the plasmepsin 2-3 piperaquine resistance locus. We identified more than 30 independent origins of artemisinin resistance, of which the KEL1 lineage accounted for 140 (91%) of 154 parasites resistant to dihydroartemisinin-piperaquine. In 2008, KEL1 combined with PLA1, the major lineage associated with piperaquine resistance. By 2013, the KEL1/PLA1 co-lineage had reached a frequency of 63% (24/38) in western Cambodia and had spread to northern Cambodia. The KEL1/PLA1 co-lineage emerged in the same year that dihydroartemisinin-piperaquine became the first-line antimalarial drug in western Cambodia and spread rapidly thereafter, displacing other artemisinin-resistant parasite lineages. These findings have important implications for management of the global health risk associated with the current outbreak of multidrug-resistant malaria in southeast Asia.

In resource-poor countries, such as Solomon Islands, the research agenda on health is often dominated by researchers from resource-rich countries. New strategies are needed to empower local researchers to set directions for health research. This paper presents a process which seeks to enable a local and potentially more equitable research agenda at a remote hospital in Solomon Islands. In preparation for a health research capacity-building workshop at Atoifi Adventist Hospital, Malaita, Solomon Islands, a computer-based search was conducted of Solomon Islands public health literature. Using a levels-of-agreement approach publications were categorised as: a) original research, b) reviews, c) program descriptions and d) commentaries or discussion. Original research publications were further sub-categorised as: i) measurement, ii) descriptive research and iii) intervention studies. Results were reviewed with Solomon Islander health professionals in a focus group discussion during the health research workshop. Focus group participants were invited to discuss reactions to literature search results and how results might assist current or future local researchers to identify gaps in the published research literature and possible research opportunities at the hospital and surrounding communities. Focus group data were analysed using a grounded theory approach. Of the 218 publications meeting inclusion criteria, 144 (66%) were categorised as 'original research', 42 (19%) as 'commentaries/discussion', 28 (13%) as 'descriptions of programs' and 4 (2%) as 'reviews'. Agreement between three authors' (MRM, DM, AC) independent categorisation was 'excellent' (0.8 <κ). The 144 'original research' publications included 115 (80%) 'descriptive studies' (κ = 0.82); 19 (13%) 'intervention studies' (κ = 0.77); and 10 (7%) 'measurement studies'(κ = 0.80). Key themes identified in the focus group discussion challenged historical inequities evident from the literature review. These included: i) who has done/is doing research in Solomon Islands (largely non-Solomon Islanders); ii) when the research was done (research needs to keep up to date); iii) amount of published research (there should be more); iv) types of research (lack of intervention and operational research); v) value of published research (important); vi) gaps in published literature (need more research about nursing); vii) opportunities for research action (start small); viii) support required to undertake research at the hospital and in surrounding communities (mentoring and partnering with experienced researchers). A search and collaborative review of public health literature for Solomon Islands at a health research capacity building workshop has uncovered and challenged historical inequity in the conduct and access to public health research. Emerging Solomon Islander researchers at a remote hospital are now working to set priorities and strengthen local research efforts. These efforts have highlighted the importance of collaboration and mentoring for Solomon Islanders to instigate and implement public health research to improve the health of individuals and communities served by this remote hospital.

Objectives To study whether systematic reviewers apply procedures to counter-balance some common forms of research malpractice such as not publishing completed research, duplicate publications, or selective reporting of outcomes, and to see whether they identify and report misconduct. Design Cross-sectional analysis of systematic reviews and survey of their authors. Participants 118 systematic reviews published in four journals (Ann Int Med, BMJ, JAMA, Lancet), and the Cochrane Library, in 2013. Main outcomes and measures Number (%) of reviews that applied procedures to reduce the impact of: (1) publication bias (through searching of unpublished trials), (2) selective outcome reporting (by contacting the authors of the original studies), (3) duplicate publications, (4) sponsors’ and (5) authors’ conflicts of interest, on the conclusions of the review, and (6) looked for ethical approval of the studies. Number (%) of reviewers who suspected misconduct are reported. The procedures applied were compared across journals. Results 80 (68%) reviewers confirmed their data. 59 (50%) reviews applied three or more procedures; 11 (9%) applied none. Unpublished trials were searched in 79 (66%) reviews. Authors of original studies were contacted in 73 (62%). Duplicate publications were searched in 81 (69%). 27 reviews (23%) reported sponsors of the included studies; 6 (5%) analysed their impact on the conclusions of the review. Five reviews (4%) looked at conflicts of interest of study authors; none of them analysed their impact. Three reviews (2.5%) looked at ethical approval of the studies. Seven reviews (6%) suspected misconduct; only 2 (2%) reported it explicitly. Procedures applied differed across the journals. Conclusions Only half of the systematic reviews applied three or more of the six procedures examined. Sponsors, conflicts of interest of authors and ethical approval remain overlooked. Research misconduct is sometimes identified, but rarely reported. Guidance on when, and how, to report suspected misconduct is needed. PMID:26936908

The dissemination of health-related news through newspapers can influence the behavior of patients and of health care providers. We conducted a study to analyze the characteristics of health-related research published by two leading Brazilian newspapers. We retrospectively evaluated health-related news published in the electronic versions of the newspapers Folha de São Paulo and O Estado de São Paulo over a period of three months (July through September, 2009). Only articles mentioning medical research were included. The articles were categorized according to topic, source, study location and the nature of the headline. We also analyzed the presence of background information on the topic, citations of medical periodicals, national contextualization and references to products or companies. Scientific research articles corresponded to 57% and 20% of health-related articles published by Folha de São Paulo and O Estado de São Paulo, respectively. Folha de São Paulo published significantly more articles about national studies, and most articles were written by its own staff. In contrast, most articles in O Estado de São Paulo came from news agencies. Folha de São Paulo also better contextualized its reports for Brazilian society. O Estado de São Paulo tended to cite the name of the periodical in which the study was published more frequently, but their articles lacked national contextualization. The results showed a significant difference in the way in which the studied newspapers report on health-related research. Folha de São Paulo tends to write its own articles and more frequently publishes the results of national research, whereas O Estado de São Paulo publishes articles that originate in news agencies, most of which have little national contextualization.

2015-03-01

While the Body Checking Questionnaire (BCQ; Reas et al., 2002) is the most commonly-used measure of body checking behaviors, findings on the factor structure in nonclinical samples are mixed. This study investigated the factor structure and psychometric properties of the BCQ among nonclinical college women. In Study 1 (n=326), an exploratory factor analysis indicated factors corresponding to (a) behavioral and (b) visual checking. In Study 2 (n=1013), a confirmatory factor analysis revealed adequate fit for these factors, better than the original or total score solutions. Scales based upon the two factors demonstrated good internal consistency, convergent validity with measures of eating pathology, and sensitivity for detecting at-risk eating pathology. Results suggest an alternate two-factor solution that differs from the original three-factor solution. Copyright © 2015. Published by Elsevier Ltd.

We summarize original research in the field of critical care nephrology accepted or published in 2005 in Critical Care and, when considered relevant or directly linked to this research, in other journals. The articles have been grouped into four categories to facilitate a rapid overview. First, physiopathology, epidemiology and prognosis of acute renal failure (ARF): an extensive review and some observational studies have been performed with the aim of describing aspects of ARF physiopathology, precise epidemiology and long-term outcomes. Second, several authors have performed clinical trials utilizing a potential nephro-protective drug, fenoldopam, with different results. Third, the issue of continuous renal replacement therapies dose has been addressed in a small prospective study and a large observational trial. And fourth, alternative indications to extracorporeal treatment of ARF and systemic inflammatory response syndrome have been explored by three original clinical studies. PMID:16919174

Melanosomes or Microbes: Testing an Alternative Hypothesis for the Origin of Microbodies in Fossil Feathers

Microbodies associated with fossil feathers, originally attributed to microbial biofilm, have been reinterpreted as melanosomes: pigment-containing, eukaryotic organelles. This interpretation generated hypotheses regarding coloration in non-avian and avian dinosaurs. Because melanosomes and microbes overlap in size, distribution and morphology, we re-evaluate both hypotheses. We compare melanosomes within feathers of extant chickens with patterns induced by microbial overgrowth on the same feathers, using scanning (SEM), field emission (FESEM) and transmission (TEM) electron microscopy. Melanosomes are always internal, embedded in a morphologically distinct keratinous matrix. Conversely, microbes grow across the surface of feathers in continuous layers, more consistent with published images from fossil feathers. We compare our results to both published literature and new data from a fossil feather ascribed to Gansus yumenensis (ANSP 23403). `Mouldic impressions' were observed in association with both the feather and sediment grains, supporting a microbial origin. We propose criteria for distinguishing between these two microbodies.

The objective of this study was to analyze and record the published evidence regarding community pharmacy practice in India during the past decade (1998-2008). A bibliometric review analysis of the original papers was undertaken to assess the different aspects of community pharmacy practice in India. The MEDLINE, Index Copernicus, IndMed, DOAJ databases and the journals such as Indian Journal of Pharmaceutical Sciences and Indian Journal of Hospital Pharmacy were used as data sources. Type of papers, type of journals, category of papers, production indicators and impact factor of the journals were analyzed. Thirty papers were included in the study. The papers were published in 13 different journals, 33.3% of them being in the Indian Journal of Hospital Pharmacy. The average number of authors per paper was 2.73 (SD=1.41). Impact factor was available for only three journals. There are limited studies being published in India which cover the community pharmacy related activities in India. The key indicators which emerge from the literature review present some fundamental challenges to the development of the role of the community pharmacist in India.

2018-02-01

The objectives of the current study were to explore the correlation between Raman spectroscopy and lipid characteristics and to assess the potential of Raman spectroscopic methods for distinguishing the different sources of animal-originated feed based on lipid characteristics. A total of 105 lipid samples derived from five animal species have been analyzed by gas chromatography (GC) and FT-Raman spectroscopy. High correlations (r 2 >0.94) were found between the characteristic peak ratio of the Raman spectra (1654/1748 and 1654/1445) and the degree of unsaturation of the animal lipids. The results of FT-Raman data combined with chemometrics showed that the fishmeal, poultry, porcine and ruminant (bovine and ovine) MBMs could be well separated based on their lipid spectral characteristics. This study demonstrated that FT-Raman spectroscopy can mostly exhibit the lipid structure specificity of different species of animal-originated feed and can be used to discriminate different animal-originated feed samples.

Obsolescence is the decrease of the validity of the information in time and is known as literature aging. To analyze the obsolescence of the literature of original articles published in 10 years in a Mexican pediatric journal. Articles published in the Clinical Bulletin of Sonora Children's Hospital (BCHIES) were analyzed. The variables were: year, volume, number, percentage of original articles, reference year, total of references per article, operational and file; articles citations and self-citations, Price Indices, Burton-Kebler and Brookes, half-life, and aging factor. The 87 original articles (37%) contained 1,726 references, and the average was 19.8 per article; operational references were 398 (23%) and the file references, 1,287 (74.5%). There were 30 (34.4%) citations to articles, and self-citations were 19 (21%), half-life, 13.2 years; the aging factor was 0.86, the annual loss of income was 14%. The percentage of original articles from the BCHIES is close to 40%, likely to improve, and in the literature archive, the aging factor reversed.

Music festivals and other temporary events, such as bicycle races, lay a heavy burden on the surrounding environment. Treatment of the wastewater originating from such events is necessary if no municipal treatment plant is available. This study demonstrated that activated carbon is a performant technique for the treatment of wastewaters originating from these temporary events. Freundlich isotherms and maximum operational linear velocity (6 m/h) were determined on a lab-scale set-up. A pilot-scale set up was used to treat part (5%) of the total volume of the Dranouter Music Festival shower wastewater. On average 90% removal of COD and suspended solids concentration was obtained. Application of the activated carbon filter resulted in the fact that the local discharge limits were met without operational problems. IWA Publishing 2008.

In 1583, Georg Bartisch, oculist and cutter for bladder stones at the court of Duke August I of Saxony, published at his own expense a 273 page textbook of ophthalmology. It contained 91 wood cuts and, in the present volume, they are presented in brilliant colour as they were in the original books prepared for presentation. The book was one of the first medical treatises to be published in the German vernacular instead of traditional Latin. It has been translated into English and published in gothic type to simulate the original. Treatment of diseases of the eye by medicines or surgery are reported in great detail. It gives an account of ophthalmology at the time of the early Renaissance when enlightenment was beginning to overtake the darkness of the Middle Ages.

Poster presentations at major meetings serve to rapidly present and share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals provides dissemination of knowledge. The purpose of this study was to evaluate the publication rate of abstracts presented at the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Meeting, to assess the factors influencing publication and determine the impact factor of these journals. All poster abstracts presented at the 2002 IFCC Meeting were included in the study. A Medline search was performed to identify a matching journal article. Topics, country of origin, study type, study center and publication year were tabulated. Journals and impact factors of publication were noted. Out of 900 presented abstracts, 125 (13.9%) were published as full-text articles. Publication rates according to topics of the meeting, country of origin and university affiliation demonstrated significant differences. Abstracts from multi-centered studies had higher publication rates, and the journals they were published in had higher impact factors than single center studies. The median impact factor of the journals was 2.093. According to regression analysis, the major predictors for publication were interventional research and university affiliation (odds ratios 2.916 and 1.782, respectively; p < 0.05). The publication rate for abstracts of this clinical chemistry meeting was lower than rates from other fields of medicine. Factors leading to failure require elucidation. Encouraging authors to submit their presentations for full-text publication might improve the rate of publication.

We use the TGAS proper motions and parallaxes as well as published and new radial velocities to study the dynamics of nearby moving groups. In particular we try to determine their age using backtracing of the individual members to a common origin. We find that the current data, probably the radial velocities, do not allow to reach a successful conclusion.

A dominant approach to genetic association studies is to perform univariate tests between genotype-phenotype pairs. However, analyzing related traits together increases statistical power, and certain complex associations become detectable only when several variants are tested jointly. Currently, modest sample sizes of individual cohorts, and restricted availability of individual-level genotype-phenotype data across the cohorts limit conducting multivariate tests. We introduce metaCCA, a computational framework for summary statistics-based analysis of a single or multiple studies that allows multivariate representation of both genotype and phenotype. It extends the statistical technique of canonical correlation analysis to the setting where original individual-level records are not available, and employs a covariance shrinkage algorithm to achieve robustness.Multivariate meta-analysis of two Finnish studies of nuclear magnetic resonance metabolomics by metaCCA, using standard univariate output from the program SNPTEST, shows an excellent agreement with the pooled individual-level analysis of original data. Motivated by strong multivariate signals in the lipid genes tested, we envision that multivariate association testing using metaCCA has a great potential to provide novel insights from already published summary statistics from high-throughput phenotyping technologies.

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

Heidenreich, Uta; Baethge, Christopher

2012-01-01

Although English is medicine's lingua franca, practising physicians in Germany express the need for articles in German. This study aimed at surveying the number and characteristics of German-language psychiatric journals in Germany. Journals were identified by the standard handbook "Fachmedien Gesundheit" as well as by an online and library search, and divided into specialty journals and general psychiatry journals. Volume 2009 of all general psychiatry journals was analyzed regarding form and content. In 2009 74 journals addressed psychiatrists, albeit many not exclusively. Ten were general psychiatry journals publishing 391 review articles and 97 original papers. They differed with regard to focus (science, education, health politics) and formal characteristics, such as circulation (500-30  000), share of academia-affiliated authors (39-93 %), female first-authors (13-44 %), COI statements (0-98 % of articles), and international visibility. While much of German psychiatric science appears in English, there are still a substantial number of original articles published in German, and there is a diverse psychiatric journal scene in Germany. © Georg Thieme Verlag KG Stuttgart · New York.

Optical spectroscopic technologies are increasingly used for cancer diagnostics. Feasibility of differentiation between malignant and healthy samples of human kidney using Fluorescence, Raman, MIR and NIR spectroscopy has been recently reported . In the present work, a simplification of NIR spectroscopy method has been studied. Traditional high-resolution NIR spectrometry was replaced by an optical sensor based on a set of light-emitting diodes at selected wavelengths as light sources and a photodiode. Two prototypes of the sensor have been developed and tested using 14 in-vitro samples of seven kidney tumor patients. Statistical evaluation of results using principal component analysis and partial least-squares discriminant analysis has been performed. Despite only partial discrimination between tumor and healthy tissue achieved by the presented new technique, the results evidence benefits of LED-based near-infrared sensing used for oncological diagnostics.

Substantial resources are being devoted to identify candidate genes for complex mental and behavioral disorders through inclusion of environmental exposures following the report of an interaction between the serotonin transporter linked polymorphic region (5-HTTLPR) and stressful life events on an increased risk of major depression. To conduct a meta-analysis of the interaction between the serotonin transporter gene and stressful life events on depression using both published data and individual-level original data. Search of PubMed, EMBASE, and PsycINFO databases through March 2009 yielded 26 studies of which 14 met criteria for the meta-analysis. Criteria for studies for the meta-analyses included published data on the association between 5-HTTLPR genotype (SS, SL, or LL), number of stressful life events (0, 1, 2, > or = 3) or equivalent, and a categorical measure of depression defined by the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) or the International Statistical Classification of Diseases, 10th Revision (ICD-10) or use of a cut point to define depression from standardized rating scales. To maximize our ability to use a common framework for variable definition, we also requested original data from all studies published prior to 2008 that met inclusion criteria. Of the 14 studies included in the meta-analysis, 10 were also included in a second sex-specific meta-analysis of original individual-level data. Logistic regression was used to estimate the effects of the number of short alleles at 5-HTTLPR, the number of stressful life events, and their interaction on depression. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated separately for each study and then weighted averages of the individual estimates were obtained using random-effects meta-analysis. Both sex-combined and sex-specific meta-analyses were conducted. Of a total of 14,250 participants, 1769 were classified as having depression; 12,481 as not having depression. In the meta-analysis of published data, the number of stressful life events was significantly associated with depression (OR, 1.41; 95% CI,1.25-1.57). No association was found between 5-HTTLPR genotype and depression in any of the individual studies nor in the weighted average (OR, 1.05; 95% CI, 0.98-1.13) and no interaction effect between genotype and stressful life events on depression was observed (OR, 1.01; 95% CI, 0.94-1.10). Comparable results were found in the sex-specific meta-analysis of individual-level data. This meta-analysis yielded no evidence that the serotonin transporter genotype alone or in interaction with stressful life events is associated with an elevated risk of depression in men alone, women alone, or in both sexes combined.

To the best of our knowledge, there has been no systematic assessment of the classification of scientific production within the scope of radiation oncology relating to central nervous system tumors. The aim of this study was to systematically assess the status of evidence relating to the central nervous system and to evaluate the geographic origins and major content of these published data. Descriptive critical appraisal study conducted at a private hospital in São Paulo, Brazil. We evaluated all of the central nervous system studies published in the journal Radiotherapy & Oncology between 2003 and 2012. The studies identified were classified according to their methodological design and level of evidence. Information regarding the geographical location of the study, the institutions and authors involved in the publication, main condition or disease investigated and time of publication was also obtained. We identified 3,004 studies published over the 10-year period. Of these, 125 (4.2%) were considered eligible, and 66% of them were case series. Systematic reviews and randomized clinical trials accounted for approximately 10% of all the published papers. We observed an increase in high-quality evidence and a decrease in low-quality published papers over this period (P = 0.036). The inter-rater reliability demonstrated significant agreement between observers in terms of the level of evidence. Increases in high-level evidence and in the total number of central nervous system papers were clearly demonstrated, although the overall number of such studies remained relatively small.

To systematically assess the literature published after 1997 describing the effectiveness of nutritional interventions in Cystic Fibrosis patients. An online search in PUBMED, EMBASE and COCHRANE databases was conducted. Original studies with 4 patients or more, describing a nutritional intervention and giving at least weight as an outcome parameter were included. The inclusion criteria were met by 17 articles, focusing on respectively behavioural interventions (n=6), oral supplementation (n=4) or enteral tube feeding (n=7). This latter intervention was universally successful to induce weight gain. One behavioural study and 2 oral supplementation studies also reported significant weight gain. Enteral tube feeding is effective to improve nutritional status, while the described effects of behavioural intervention and oral supplementation are not consistent at present.

This investigation presents a review of all of the clinical outcome measures used by authors and published in the Journal of the American Podiatric Medical Association and the Journal of Foot and Ankle Surgery from January 1, 2011, to December 31, 2015. Of 1,336 articles published during this time frame, 655 (49.0%) were classified as original research and included in this analysis. Of these 655 articles, 151 (23.1%) included at least one clinical outcome measure. Thirty-seven unique clinical outcome scales were used by authors and published during this period. The most frequently reported scales in the 151 included articles were the American Orthopaedic Foot and Ankle Society scales (54.3%; n = 82), visual analog scale (35.8%; n = 54), Medical Outcomes Study Short Form Health Survey (any version) (10.6%; n = 16), Foot Function Index (5.3%; n = 8), Maryland Foot Score (4.0%; n = 6), and Olerud and Molander scoring system (4.0%; n = 6). Twenty-four articles (15.9%) used some form of original/subjective measure of patient satisfaction/expectation. The results of this investigation detail the considerable variety of clinical outcome measurement tools used by authors in the Journal of the American Podiatric Medical Association and the Journal of Foot and Ankle Surgery and might support the need for a shift toward the consistent use of a smaller number of valid, reliable, and clinically useful scales in the podiatric medical literature.

Diseases of the kidneys and genitourinary tract are common health problems that affect people of all ages and demographic backgrounds. In this study, we compared the quantity and quality of nephrological and urological articles published in international journals from the three major regions of China: the mainland (ML), Hong Kong (HK), and Taiwan (TW). Nephrological and urological articles originating from ML, TW, and HK that were published in 61 journals from 1999-2008 were retrieved from the PubMed database. We recorded the numbers of total articles, clinical trials, randomized controlled trials, case reports, impact factors (IF), citations, and articles published in the leading general-medicine journals. We used these data to compare the quantity and quality of publication output from the three regions. The total number of articles increased significantly from 1999 to 2008 in the three regions. The number of articles from ML has exceeded that from HK since 2004, and surpassed that from TW in 2008. Publications from TW had the highest accumulated IF, total citations of articles, and the most articles published in leading general-medicine journals. However, HK publications had the highest average IF. Although ML produced the largest quantity of articles, it exhibited the lowest quality among the three regions. The number of nephrological and urological publications originating from the three major regions of China increased significantly from 1999 to 2008. The annual number of publications by ML researchers exceeded those from TW and HK. However, the quality of articles from TW and HK was higher than that from ML.

The frequency with which a scientific article is cited by other studies is one way to measure its academic influence. A comprehensive search was performed to identify journal articles in the otorhinolaryngology subject category of the 2013 Journal Citation Report Science Edition over the last 30 years (1985-2014). The 100 most cited articles were reviewed and basic information including the publication year, country of origin, source journal, article type and research field was collected. The 100 most cited articles were published in 15 of the 44 otorhinolaryngology journals. The number of citations per article ranged between 208 and 1559. The leading research field was otology and neurotology (n = 50), followed by rhinology (n = 23) and head and neck surgery (n = 11). Most papers originated in the USA (n = 64). The possibility of an article being cited is influenced by the publication language, country of origin and source journal.

No evidence of 1918 influenza pandemic origin in Chinese laborers/soldiers in France.

Shanks, G Dennis

2016-01-01

Laborers and soldiers from China and Southeast Asia recruited during the First World War by Britain and France have been suggested as the origin of the 1918 influenza pandemic in Western Europe. This study aimed to review the available data to better understand the sources and origins of the 1918 influenza pandemic, and clarify whether, in fact, there was an Asian connection to its onset. We reviewed official mortality lists from the Commonwealth War Graves Commission and the French Ministry of Defence for all-cause (Britain) and pneumonia/influenza (France) mortality, respectively. The results indicated that influenza mortality (estimated 1/1000) in Chinese and Southeast Asian laborers and soldiers lagged other co-located military units by several weeks. This finding does not support a Southeast Asian importation of lethal influenza to Europe in 1918. Copyright © 2015. Published by Elsevier Taiwan LLC.

Patients presenting with abdominal pain and pneumoperitoneum in radiological examination usually require emergency explorative laparoscopy or laparotomy. Pneumoperitoneum mostly associates with gastrointestinal perforation. There are very few cases where surgery can be avoided. We present 2 cases of pneumoperitoneum with unknown origin and successful conservative treatment. Both patients were elderly women presenting to our emergency unit, with moderate abdominal pain. There was neither medical intervention nor trauma in their medical history. Physical examination revealed mild abdominal tenderness, but no clinical sign of peritonitis. Cardiopulmonary examination remained unremarkable. Blood studies showed only slight abnormalities, in particular, inflammation parameters were not significantly increased. Finally, obtained CTs showed free abdominal gas of unknown origin in both cases. We performed conservative management with nil per os, nasogastric tube, total parenteral nutrition and prophylactic antibiotics. After 2 weeks, both were discharged home. 2016 BMJ Publishing Group Ltd.

Charles Darwin and the origin of life.

PubMed

Peretó, Juli; Bada, Jeffrey L; Lazcano, Antonio

2009-10-01

When Charles Darwin published The Origin of Species 150 years ago he consciously avoided discussing the origin of life. However, analysis of some other texts written by Darwin, and of the correspondence he exchanged with friends and colleagues demonstrates that he took for granted the possibility of a natural emergence of the first life forms. As shown by notes from the pages he excised from his private notebooks, as early as 1837 Darwin was convinced that "the intimate relation of Life with laws of chemical combination, & the universality of latter render spontaneous generation not improbable". Like many of his contemporaries, Darwin rejected the idea that putrefaction of preexisting organic compounds could lead to the appearance of organisms. Although he favored the possibility that life could appear by natural processes from simple inorganic compounds, his reluctance to discuss the issue resulted from his recognition that at the time it was possible to undertake the experimental study of the emergence of life.

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.

INVESTIGACION CLINICA was founded by the initiative of Américo Negrette, who became its first editor, and it has been published uninterruptedly since July 1960, with a quarterly frequency. The first issues consisted mainly of a collection of reviews of seminars held at the now called Instituto de Investigaciones Clínicas "Dr. Américo Negrette", Facultad de Medicina, Universidad del Zulia, its publisher. Very soon, original research results from this institution were included in the novel journal. In the 60's, papers on results obtained during the outbreaks of Venezuelan Equine Encephalitis present in the area, were prominent. Originally, the journal published 3-4 papers, but due to the increased number of contributions, in 2001, its format changed from 1/16 to 1/8, and now each number includes 11 original articles. Currently, INVESTIGACION CLINICA publishes 44 papers a year, in Spanish or English on different biomedical topics, from contributors all around the world. Progressively it has been included in different renowned indexes, such as PubMed/MEDLINE, Science Citation Index Expanded, Excerpta Medica, Tropical Diseases Bulletin, Copernicus, Scopus, Periodica, and several others. Besides, it can be found in open access through www.Scielo.org.ve, www.freemedicaljournals.com and in our new Web page: https://sites. google.com/site/revistainvestigacionesclinicas/home. Most papers published in INVESTIGACION CLINICA have been cited in the regional or foreign literature accumulating more than 1200 citations by now. For this particular issue, to celebrate the 50th anniversary of INVESTIGACION CLINICA, we have invited some of our more recent referees or authors to contribute with Reviews in their respective areas of expertise.

Noachian and Hesperian modification of the original Chryse impact basin topography

NASA Technical Reports Server (NTRS)

Stockman, Stephanie; Frey, Herbert

1994-01-01

We propose a new center (35.5 W, 32.5 N) and ring assignment for the original Chryse impact basin based on photogeologic mapping and re-examination of the published geology. Noachian features in the Chryse Planitia area are the best indicators of the original ancient multiringed impact structure. While other workers have centered the Chryse impact on the topographic low associated with Hesperian volcanic and fluvial deposits, we suggest that the center of the original Noachian-age excavation cavity was located 800 km farther NE, and the basin topography was significantly modified over time.

The point of departure for the present work is the observation that, in comparison with Anglo-American countries or the Netherlands, Germany was responsible for only a marginal number of international publications in the field of medical education research before 2004. Recent years, however, have seen an increase in the importance of medical education research in Germany. The objective of this article is to evaluate the extent to which this trend can be substantiated by increased German publishing activity since the year 2004 in international, English-language journals in the subject area of "medical education research". In the framework of a literature and content analysis, German-author articles from the years 2004 to 2013 in six international, English-language medical education research journals were evaluated. In order to obtain an overview of German research activity in this area, all project and original works with German first and last authors were identified and subjected to a more in-depth content analysis. In total, 10,055 articles were examined. The evaluation shows that between the years 2004 and 2013 179 articles (of which 145 are project or original works) by German authors were published in the journals examined. Fluctuations over the course of time were evidenced. The project and original works are primarily cross-sectional studies (27.8%) and randomised control studies (25.6%) on the subject of "teaching and learning methods" (43.6%). In comparison with the years 2004-2008, a significant rise can be seen in the number of publications by German education researchers in international journals since the year 2009.

Twice-yearly meetings of The British Society of Rehabilitation Medicine (BSRM) take place at which posters and free papers are generated, as abstracts, to present novel research findings, audits and case reports. The aim of this study was to evaluate the academic value of these meetings, by determining the subsequent rate of publication in peer-reviewed journals of abstracts presented. This was compared to the publication rate of other European medical specialist society meetings. The authors used MEDLINE, PubMed and Google Scholar search engines to look for publication of abstracts presented at BSRM meetings within peer-reviewed journals over a 7-year period (2000-2006). The abstracts were categorised into sub-groups (original study, audit, review, case report and service description) to determine which type was more likely to be published. The above databases were used also to extract studies on publication rate of other medical specialties in Europe. In 7 years, a total of 251 abstracts (of which 152 are original studies) have been presented as free papers or posters in a total of 13 meetings. The publication rate for the described study categories were: total 34%, original study 52%, review 50%, case report 5%, audit 0% and service description 0%. Publication rates from other specialist meetings in Europe range from 10% to 70%. The average publication rate for an abstract submitted to a BSRM meeting is 34% for any abstract and 52% for an original study suggesting that the meeting is generating abstracts of comparable academic interest to other specialist societies.

The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). Descriptive study at Brazilian Cochrane Center. All the published articles were evaluated according to merit assessment (content) and form assessment (performance). Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives. These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

The present study seeks to extend previous research regarding literature related to gay, lesbian, and bisexual (GLB) issues published in couple and family therapy (CFT)-related journals by presenting the results from a content analysis of GLB studies in CFT-related journals from 1996 to 2010. Results of the analysis revealed a 238.8% increase in total GLB content published since the original review. Articles pertaining to therapy with GLB clients continue to represent the largest area of publication. With one exception, all surveyed journals showed an increase in the percentage of GLB content since the first study. Emerging areas of research include studies related to supervision and training, GLB mental health and substance use, and sexual minority adolescents.

Introduction: A meta-analysis is a statistical and analytical method which combines and synthesizes different independent studies and integrates their results into one common result. Goal: Analysis of the journals “Medical Archives”, “Materia Socio Medica” and “Acta Informatica Medica”, which are located in the most eminent indexed databases of the biomedical milieu. Material and methods: The study has retrospective and descriptive character, and included the period of the calendar year 2014. Study included six editions of all three journals (total of 18 journals). Results: In this period was published a total of 291 articles (in the “Medical Archives” 110, “Materia Socio Medica” 97, and in “Acta Informatica Medica” 84). The largest number of articles was original articles. Small numbers have been published as professional, review articles and case reports. Clinical events were most common in the first two journals, while in the journal “Acta Informatica Medica” belonged to the field of medical informatics, as part of pre-clinical medical disciplines. Articles are usually required period of fifty to fifty nine days for review. Articles were received from four continents, mostly from Europe. The authors are most often from the territory of Bosnia and Herzegovina, then Iran, Kosovo and Macedonia. Conclusion: The number of articles published each year is increasing, with greater participation of authors from different continents and abroad. Clinical medical disciplines are the most common, with the broader spectrum of topics and with a growing number of original articles. Greater support of the wider scientific community is needed for further development of all three of the aforementioned journals. PMID:25870484

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

Accuracy of cited “facts” in medical research articles: A review of study methodology and recalculation of quotation error rate

PubMed Central

2017-01-01

Previous reviews estimated that approximately 20 to 25% of assertions cited from original research articles, or “facts,” are inaccurately quoted in the medical literature. These reviews noted that the original studies were dissimilar and only began to compare the methods of the original studies. The aim of this review is to examine the methods of the original studies and provide a more specific rate of incorrectly cited assertions, or quotation errors, in original research articles published in medical journals. Additionally, the estimate of quotation errors calculated here is based on the ratio of quotation errors to quotations examined (a percent) rather than the more prevalent and weighted metric of quotation errors to the references selected. Overall, this resulted in a lower estimate of the quotation error rate in original medical research articles. A total of 15 studies met the criteria for inclusion in the primary quantitative analysis. Quotation errors were divided into two categories: content ("factual") or source (improper indirect citation) errors. Content errors were further subdivided into major and minor errors depending on the degree that the assertion differed from the original source. The rate of quotation errors recalculated here is 14.5% (10.5% to 18.6% at a 95% confidence interval). These content errors are predominantly, 64.8% (56.1% to 73.5% at a 95% confidence interval), major errors or cited assertions in which the referenced source either fails to substantiate, is unrelated to, or contradicts the assertion. Minor errors, which are an oversimplification, overgeneralization, or trivial inaccuracies, are 35.2% (26.5% to 43.9% at a 95% confidence interval). Additionally, improper secondary (or indirect) citations, which are distinguished from calculations of quotation accuracy, occur at a rate of 10.4% (3.4% to 17.5% at a 95% confidence interval).

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.

A Bayesian Perspective on the Reproducibility Project: Psychology

PubMed Central

Etz, Alexander; Vandekerckhove, Joachim

2016-01-01

We revisit the results of the recent Reproducibility Project: Psychology by the Open Science Collaboration. We compute Bayes factors—a quantity that can be used to express comparative evidence for an hypothesis but also for the null hypothesis—for a large subset (N = 72) of the original papers and their corresponding replication attempts. In our computation, we take into account the likely scenario that publication bias had distorted the originally published results. Overall, 75% of studies gave qualitatively similar results in terms of the amount of evidence provided. However, the evidence was often weak (i.e., Bayes factor < 10). The majority of the studies (64%) did not provide strong evidence for either the null or the alternative hypothesis in either the original or the replication, and no replication attempts provided strong evidence in favor of the null. In all cases where the original paper provided strong evidence but the replication did not (15%), the sample size in the replication was smaller than the original. Where the replication provided strong evidence but the original did not (10%), the replication sample size was larger. We conclude that the apparent failure of the Reproducibility Project to replicate many target effects can be adequately explained by overestimation of effect sizes (or overestimation of evidence against the null hypothesis) due to small sample sizes and publication bias in the psychological literature. We further conclude that traditional sample sizes are insufficient and that a more widespread adoption of Bayesian methods is desirable. PMID:26919473

Geospatial Health is an international, peer-reviewed scientific journal produced by the Global Network for Geospatial Health (GnosisGIS). This network was founded in 2000 and the inaugural issue of its official journal was published in November 2006 with the aim to cover all aspects of geographical information system (GIS) applications, remote sensing and other spatial analytic tools focusing on human and veterinary health. The University of Naples Federico II is the publisher, producing two issues per year, both as hard copy and an open-access online version. The journal is referenced in major databases, including CABI, ISI Web of Knowledge and PubMed. In 2008, it was assigned its first impact factor (1.47), which has now reached 1.71. Geospatial Health is managed by an editor-in-chief and two associate editors, supported by five regional editors and a 23-member strong editorial board. This overview takes stock of the first five years of publishing: 133 contributions have been published so far, primarily original research (79.7%), followed by reviews (7.5%), announcements (6.0%), editorials and meeting reports (3.0% each) and a preface in the first issue. A content analysis of all the original research articles and reviews reveals that three quarters of the publications focus on human health with the remainder dealing with veterinary health. Two thirds of the papers come from Africa, Asia and Europe with similar numbers of contributions from each continent. Studies of more than 35 different diseases, injuries and risk factors have been presented. Malaria and schistosomiasis were identified as the two most important diseases (11.2% each). Almost half the contributions were based on GIS, one third on spatial analysis, often using advanced Bayesian geostatistics (13.8%), and one quarter on remote sensing. The 120 original research articles, reviews and editorials were produced by 505 authors based at institutions and universities in 52 countries. Importantly, a considerable proportion of the authors come from countries with a low or medium human development index (29.3%). In view of the increasing number of submissions, we are considering to publish more than two issues per year in the future. Finally, our vision is to open-up a new section predominantly based on visual presentations, including brief video clips, as discussed in a symposium at the 60th annual meeting of the American Society of Tropical Medicine and Hygiene in December 2011.

The source of research funding can result in bias, and its disclosure is essential in the publication of results. The aim of the study is to identify the frequency and type of sources of funding in the articles published by four Spanish biomedical journals published in Spanish. The frequency and type of financial disclosures in the articles published during 2012 in the ordinary numbers of Atención Primaria, Medicina Clínica, Revista Clínica Española and Revista Española de Cardiología were analyzed. Articles described as "Editorial", "Original article", "Consensus Document", "Review" and "Special Article" were considered. It was decided in each case whether or not the article included any funding disclosure and the type of the declared funding (public or private). Four hundred and twelve publications were analyzed. In 32.5% there was disclosure of funding: 38% in Atención Primaria, 27% in Medicina Clínica, 15% in Revista Clínica Española and 45% in Revista Española de Cardiología. By type of articles, 47% of original articles, 44% of consensus documents, 21% of reviews, 14% of special articles and 8% of editorials had a funding source. In 51.5% of the cases, funding was exclusively public, in 36.5% exclusively private and in 10% mixed. There is considerable variability in the disclosure of funding sources in articles appearing in these four Spanish biomedical journals. It would be necessary to improve the disclosure requirements of sources of funding, making them uniform, clear and transparent.

The aim of the present study was to perform a bibliometric analysis of the gender distribution of first and senior authorships in important oral and maxillofacial journals over the 30-year period from 1980 to 2010. Articles published in three representative oral and maxillofacial surgery journals were selected. The years 1980, 1990, 2000, and 2010 were chosen as representative points in time for article selection. Original research, case reports, technical notes, and reviews were included in the analysis. Case reports and technical notes were pooled in one group. For each article, the gender of the first author as well as that of the senior author was determined, based on the inspection of their first name. The type of article was determined and the country of origin of the article was documented. A total 1412 articles were subjected to the data analysis. A significant increase in female authorship in oral and maxillofacial surgery could be identified over the chosen 30-year period. However, the number of publications by male authors was still significantly higher at all points of time, exceeding those of female authors by at least 3.8 fold in 2010. As there is a trend towards feminization of medicine and dentistry, the results of the present study may serve as the basis for further analysis of the current situation, and the identification of necessary actions to accelerate the closure of the gender gap in publishing in oral and maxillofacial surgery.

2013-01-01

Background: This is an analysis of papers published by Iranian neurosurgeons while working in Iran until the year 2010. Methods: We collected bibliometric data and assigned a level of evidence (LOE) for each paper and compared neurosurgical research productivity across three time periods (before 1990, between 1991 and 2000, and after 2000). For further illustration, the annual growth rates of Iranian publications were calculated for all papers published after 1995. Results: We found a total of 1196 papers by 422 Iranian neurosurgeons. Five authors accounted for 22.9% of the papers. The average number of authors for each published manuscript was 3.48 and increased significantly from 2.0 to 4.0 across the three investigated periods (P < 0.001). 58.9% of Iranian papers were published in local journals only. A total of 74.6% articles were published after 2000, which was a significant increase compared with the decades before (P < 0.001). Original articles and case reports accounted for 63.8% and 31.1% of the publications, respectively. The proportion of case reports decreased while the proportion of original articles increased across the three time periods (P < 0.001). The adjusted growth rate for the total number of publications, original articles, case reports, clinical trials, and randomized clinical trials (RCTs) were 14.4%, 16.6%, 10.7%, 13.46%, and 14.7% per year, respectively. Overall, the four most frequently investigated topics were spine (27.3%), trauma (22.3%), tumor (19.1%), and vascular diseases (13.5%). The mean impact factor for journals publishing these studies and average number of citations for each paper (obtained from web of science) were found to be 1.2 and 5.46, respectively. A partitioning of these publications into assigned categories reflecting the LOE of each paper yielded the following LOE distribution for all assessed publications: Ib: 6.02%, Ic: 0.3%, IIa: 0.2%, IIb: 5.4%, IIc: 0.41%, IIIb: 4.8%, IV: 22.5%, and V: 1.2%. The relative number of publications categorized into higher LOE classes increased over the three investigated periods (P = 0.003). Based on growth curve model, the rate of increase in total numbers of publications following each position change from nonuniversity affiliated neurosurgeon to university affiliated and from university affiliated neurosurgeon to chairman university affiliated neurosurgeon was 81%. Conclusions: A considerable increase in amount and quality of Iranian papers was observed during the past decade as reflected in a higher number of papers categorized in upper LOE classes.

The average number of authors for each published manuscript was 3.48 and increased significantly from 2.0 to 4.0 across the three investigated periods (P < 0.001). 58.9% of Iranian papers were published in local journals only. A total of 74.6% articles were published after 2000, which was a significant increase compared with the decades before (P < 0.001). Original articles and case reports accounted for 63.8% and 31.1% of the publications, respectively. The proportion of case reports decreased while the proportion of original articles increased across the three time periods (P < 0.001). The adjusted growth rate for the total number of publications, original articles, case reports, clinical trials, and randomized clinical trials (RCTs) were 14.4%, 16.6%, 10.7%, 13.46%, and 14.7% per year, respectively. Overall, the four most frequently investigated topics were spine (27.3%), trauma (22.3%), tumor (19.1%), and vascular diseases (13.5%). The mean impact factor for journals publishing these studies and average number of citations for each paper (obtained from web of science) were found to be 1.2 and 5.46, respectively. A partitioning of these publications into assigned categories reflecting the LOE of each paper yielded the following LOE distribution for all assessed publications: Ib: 6.02%, Ic: 0.3%, IIa: 0.2%, IIb: 5.4%, IIc: 0.41%, IIIb: 4.8%, IV: 22.5%, and V: 1.2%. The relative number of publications categorized into higher LOE classes increased over the three investigated periods (P = 0.003). Based on growth curve model, the rate of increase in total numbers of publications following each position change from nonuniversity affiliated neurosurgeon to university affiliated and from university affiliated neurosurgeon to chairman university affiliated neurosurgeon was 81%. A considerable increase in amount and quality of Iranian papers was observed during the past decade as reflected in a higher number of papers categorized in upper LOE classes.

GLOFs in the WOS: bibliometrics, geographies and global trends of research on glacial lake outburst floods (Web of Science, 1979-2016)

Research on glacial lake outburst floods (GLOFs) - specific low-frequency, high-magnitude floods originating in glacial lakes, including jökulhlaups - is well justified in the context of glacier ice loss and glacial lake evolution in glacierized areas all over the world. Increasing GLOF research activities, which are documented by the increasing number of published research items, have been observed in the past few decades; however, comprehensive insight into the GLOF research community, its global bibliometrics, geographies and trends in research is missing. To fill this gap, a set of 892 GLOF research items published in the Web of Science database covering the period 1979-2016 was analysed. General bibliometric characteristics, citations and references were analysed, revealing a certain change in the publishing paradigm over time. Furthermore, the global geographies of research on GLOFs were studied, focusing on (i) where GLOFs are studied, (ii) who studies GLOFs, (iii) the export of research on GLOFs and (iv) international collaboration. The observed trends and links to the challenges ahead are discussed and placed in a broader context.

Lung-cancer mortality among Vermont granite workers: factors influencing exposure-response evaluation.

PubMed

Vacek, Pamela M; Callas, Peter W

2017-03-01

To understand why 2 studies relating crystalline silica exposure to lung-cancer mortality in Vermont granite workers yielded conflicting results. Data used in the 2 studies were linked to identify discrepancies. Mortality data and employment histories from the earlier study were revised based on data obtained in the later study. SMR were computed and Poisson regressions corresponding to those in the earlier study were performed using the original and revised data. Analyses were repeated with the addition of workers omitted from the earlier study. After correction of incomplete mortality and employment information in the original data, the overall SMR for the cohort in the earlier study increased from 1.17 (95% CI 1.03 to 1.36) to 1.39 (95% CI 1.22 to 1.59), and was similar to the SMR of 1.37 observed in the later study (95% CI 1.23 to 1.52). The exposure-response relationship was attenuated, particularly when person-years in all exposure categories were included in the analysis. Inclusion of additional workers had a smaller impact on the SMRs but further attenuated the exposure-response relationship. Differing results from the 2 studies are partly attributable to incomplete vital status and work history information used in the earlier study, as well as differences in cohort inclusion criteria. However, differences in length of follow-up and other factors likely play a larger role. Published by the BMJ Publishing Group Limited.

The question of whether children should be told of their biological origins is one of the most controversial issues regarding the birth of children through donated eggs, sperm, embryos or surrogacy. In the sixth phase of this longitudinal study when the children were aged 14 years, family relationships and adolescent adjustment were examined in 87 families created through reproductive donation and 54 natural conception families. The quality of family relationships was assessed by standardised interview with mothers and by standardised questionnaires and an observational measure with mothers and adolescents. Adolescent adjustment was assessed using standardised questionnaires. Systematic information on whether and when parents had told children about their biological origins was obtained at earlier phases of the study. There were no overall differences between disclosing families and either nondisclosing or natural conception families. However, within the disclosing families, more positive family relationships and higher levels of adolescent wellbeing were found for adolescents who had been told about their biological origins before age 7. The earlier children born through reproductive donation are told about their biological origins, the more positive are the outcomes in terms of the quality of family relationships and psychological wellbeing at adolescence. © 2016 The Authors.

Takahashi, Hiroshi; Akabane, Akira; Shozawa, Jun; Tamaki, Toyomi

The aim of this study is to examine the teaching of physics experiment at elementary and secondary school levels at the time when Japanese science education commenced. In this report, we focused on the first Japanese textbook of physics experiment, Rika-Shoshi, published in 1882 and the editor of the book, Udagawa Jun'ichi. Many experiments in Rika-Shoshi can be performed using low-cost everyday materials. We compare Rika-Shoshi with the original English textbooks and describe Udagawa's physics teaching in the Gunma Normal School based on the documents in the Gunma University archives. We discuss how we can learn from physics education as taught about 130 years ago.

Recently, it was proposed that the noninvasive encapsulated follicular variant of papillary thyroid carcinoma (noninvasive E-FVPTC) start to be called "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP). 1 As the original cohort of 109 patients with NIFTP studied by the consensus conference included only tumors which were equal or more than 1 cm in size, the consensus diagnostic criteria of NIFTP did not explicitly address subcentimeter lesions. 1,2 In fact, in a recent review published in this journal, Hung & Barletta recognize that there are a few published subcentimetre NIFTP in the literature. 3 This article is protected by copyright.

RADIAL PROFILE OF THE 3.5 keV LINE OUT TO R {sub 200} IN THE PERSEUS CLUSTER

The recent discovery of the unidentified emission line at 3.5 keV in galaxies and clusters has attracted great interest from the community. As the origin of the line remains uncertain, we study the surface brightness distribution of the line in the Perseus cluster since that information can be used to identify its origin. We examine the flux distribution of the 3.5 keV line in the deep Suzaku observations of the Perseus cluster in detail. The 3.5 keV line is observed in three concentric annuli in the central observations, although the observations of the outskirts of the cluster did not revealmore » such a signal. We establish that these detections and the upper limits from the non-detections are consistent with a dark matter decay origin. However, absence of positive detection in the outskirts is also consistent with some unknown astrophysical origin of the line in the dense gas of the Perseus core, as well as with a dark matter origin with a steeper dependence on mass than the dark matter decay. We also comment on several recently published analyses of the 3.5 keV line.« less

For scientists, authorship is academic currency. Authorship characteristics have been studied in a subset of the surgical and medical literature, but trends in the specialty of hand surgery have not yet been investigated. Specifically, a longitudinal analysis of number, educational training, sex, and geographical origin of authors has not been conducted. We explored the progression of authorship of scientific articles in a leading hand surgery journal. We recorded number of authors, number of references, degrees, and sex of the first and senior authors as well as geographical origin of the corresponding author in The Journal of Hand Surgery in 1985, 1995, 2005, and 2015. All original work was analyzed. A total of 892 articles were reviewed. The mean number of authors per article increased significantly from 2.6 in 1985 to 3.9 in 2015 and the number of references increased significantly from 13.7 in 1985 to 22.6 in 2015. There was a significant increase in the proportion of first authors with an MD/PhD, PhD, master's or bachelor's degree since 1985. During that same time period, a decrease in the proportion of first authors who held solely an MD was seen. There was a significant increase in proportion of the number of last authors with an MD/PhD, PhD or Master's degree in that same time period. There has been significant growth in publications originating from the "Far East" and "Other" regions, with 4.2% and 5.0% of publications, respectively, in 1985 having increased to 10.3% and 7.4% of publications, respectively, in 2015. Female first authorship significantly increased over the study period from 7.9% in 1985 to 22.1% of publications in 2015. There has been a significant increase in number of authors per article in The Journal of Hand Surgery. Similar to other studies, we noted shifts in the degrees most commonly held by authors, an increase in references per article, and a greater representation of international authors in the hand surgery. In addition, the proportion of manuscripts written by female authors has increased in the past 30 years, with the largest increase occurring between 2005 and 2015. This manuscript strives to provide further insight into the changing characteristics of authors contributing to the hand surgery literature. With increased pressure to publish in academia, it is important to understand how publishing author characteristics have evolved over time. In addition, the published literature of a field could be considered one repository of the insights and advancements of the field. One would hope that the authors contributing to that literature are a deep and wide reflection of the people working in that field. Analyzing authorship is one way to assess the breadth and depth of contributions from the profession. Copyright © 2017 American Society for Surgery of the Hand. Published by Elsevier Inc.

2017-07-21

The advent of telemedicine has allowed physicians to deliver medical treatment to patients from a distance. Mobile apps such as WhatsApp Messenger, an instant messaging service, came as a novel concept in all fields of social life, including medicine. The use of instant messaging services has been shown to improve communication within medical teams by providing means for quick teleconsultation, information sharing, and starting treatment as soon as possible. The aim of this study was to perform a comprehensive systematic review of present literature on the use of the WhatsApp Messenger app as an adjunctive health care tool for medical doctors. Searches were performed in PubMed, EMBASE, and the Cochrane Library using the term "whatsapp*" in articles published before January 2016. A bibliography of all relevant original articles that used the WhatsApp Messenger app was created. The level of evidence of each study was determined according to the Oxford Levels of Evidence ranking system produced by the Oxford Centre for Evidence-Based Medicine. The impact and the indications of WhatsApp Messenger are discussed in order to understand the extent to which this app currently functions as an adjunctive tool for telemedicine. The database search identified a total of 30 studies in which the term "whatsapp*" was used. Each article's list of references was evaluated item-by-item. After literature reviews, letters to the editor, and low-quality studies were excluded, a total of 10 studies were found to be eligible for inclusion. Of these studies, 9 had been published in the English language and 1 had been published in Spanish. Five were published by medical doctors. The pooled data presents compelling evidence that the WhatsApp Messenger app is a promising system, whether used as a communication tool between health care professionals, as a means of communication between health care professionals and the general public, or as a learning tool for providing health care information to professionals or to the general population. However, high-quality and properly evaluated research is needed, as are improvements in descriptions of the methodology and the study processes. These improvements will allow WhatsApp Messenger to be categorically defined as an effective telemedicine tool in many different fields of health care. ©Vincenzo Giordano, Hilton Koch, Alexandre Godoy-Santos, William Dias Belangero, Robinson Esteves Santos Pires, Pedro Labronici.

Several reports indicate the presence of small tissue cysts associated with Sarcocystis neurona infections. Several failed attempts to develop tissue cysts in potential intermediate host using in vitro derived parasites originally isolated from horses with equine protozoal myeloencephalitis suggest that the experimental methods to achieve bradyzoites with those isolates was not possible. Those prior studies reported the lack of detectable sarcocysts based on histology and in vivo feeding trials. A recent report of successful production and detection of small sarcocysts triggered us to review archived tissues from earlier experimental infection studies. The retrospective review sought to determine if small sized sarcocysts were not detected due to their relatively smaller size and infrequency as compared to larger sized sarcocysts produced with other isolates in these experimental inoculation trials. Tissues from two prior in vivo inoculation studies, involving in vitro-produced parasites inoculated into laboratory-reared cats and raccoons, were re-examined by immunohistochemistry staining to more easily detect the tissue cysts. In the experimental cat study no small tissue cysts were seen, consistent with the original publication results. However, in the experimental raccoon study, one raccoon inoculated with an EPM-derived isolate, SN-UCD1, had small sarcocysts not reported in the original publication. This retrospective study suggests that much closer scrutiny of tissues, including the use of immunohistochemistry on tissue sections is required to detect the smaller S. neurona sarcocysts associated with the experimental inoculations of the isolates originally derived from horses with EPM.

The governments and organizations responsible for scientific policies try to encourage equality of gender, among their priorities that of obtaining equal participation and full integration of women in all aspects of the scientific profession. The study analyzes the scientific production of women in the areas of Psychiatry by means of the bibliometric study of the papers published in ACTAS ESPANOLAS DE PSIQUIATRIA. A total of 458 papers published from 1999- 2006 period were downloaded from the Science Citation Index-Expanded database, these including original research papers, review articles and clinical cases. A bibliometric study broken down by gender was carried out to determine the existence or inequalities between men and women regarding scientific productivity, type of document, order of author signatures, on the institutional and geographical level. The papers were published by 1,194 different authors. The gender of 977 authors was identified, 587 (60.08%) men and 390 (39.92%) women. The percentage of women authorship has risen from 29.92% in 1999 to 38.86% in 2006. A total of 42.92% of authors having one published article were women, while (those with more than nine articles) only accounted for 33%. Bibliometric studies on scientific activity provide essential information to promote gender equality. An annual increase over 1% in the number of female authors in the journal has been observed, which if it continues will lead to a parity in coming years.

The "fourth disease" of childhood: reevaluation of a nonexistent disease.

PubMed

Morens, D M; Katz, A R

1991-09-15

Observed and described between 1884 and 1900, "fourth disease" (Dukes disease) followed measles, scarlet fever, and rubella as the fourth clinically characterized childhood exanthem. Like rubella ("third disease") and erythema infectiosum ("fifth disease"), accepted by the medical community at about the same time, the existence of fourth disease was initially controversial. Over the following decades descriptions of hundreds of cases, outbreaks, and laboratory studies were published in the indexed medical literature. Unlike rubella and fifth disease, however, fourth disease was not subsequently proven to exist by either epidemiologic criteria or isolation of an etiologic agent. By the 1930s, it was infrequently recognized and by the 1960s had been dropped from textbooks. In this study, the authors use epidemiologic methods to reevaluate published data on English schoolchildren from 1892 to 1900 upon which the original fourth disease claim of Dukes was based. The authors conclude that fourth disease never existed. Reinterpretation of the original data suggests that cases can be completely explained as misdiagnosed rubella and scarlet fever. Misidentification of fourth disease is attributed to failures in the critical abilities of the medical and scientific communities at the time. The implications of erroneously identifying a nonexistent disease suggest that modern scientific approaches to disease identification are sound.

Physiologically based pharmacokinetic toolkit to evaluate environmental exposures: Applications of the dioxin model to study real life exposures.

Chlorinated dibenzo-p-dioxins (CDDs) are a series of mono- to octa-chlorinated homologous chemicals commonly referred to as polychlorinated dioxins. One of the most potent, well-known, and persistent member of this family is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). As part of translational research to make computerized models accessible to health risk assessors, we present a Berkeley Madonna recoded version of the human physiologically based pharmacokinetic (PBPK) model used by the U.S. Environmental Protection Agency (EPA) in the recent dioxin assessment. This model incorporates CYP1A2 induction, which is an important metabolic vector that drives dioxin distribution in the human body, and it uses a variable elimination half-life that is body burden dependent. To evaluate the model accuracy, the recoded model predictions were compared with those of the original published model. The simulations performed with the recoded model matched well with those of the original model. The recoded model was then applied to available data sets of real life exposure studies. The recoded model can describe acute and chronic exposures and can be useful for interpreting human biomonitoring data as part of an overall dioxin and/or dioxin-like compounds risk assessment.

Recently, several high profile studies collected cell viability data from panels of cancer cell lines treated with many drugs applied at different concentrations. Such drug sensitivity data for cancer cell lines provide suggestive treatments for different types and subtypes of cancer. Visualization of these datasets can reveal patterns that may not be obvious by examining the data without such efforts. Here we introduce Drug/Cell-line Browser (DCB), an online interactive HTML5 data visualization tool for interacting with three of the recently published datasets of cancer cell lines/drug-viability studies. DCB uses clustering and canvas visualization of the drugs and the cell lines, as well as a bar graph that summarizes drug effectiveness for the tissue of origin or the cancer subtypes for single or multiple drugs. DCB can help in understanding drug response patterns and prioritizing drug/cancer cell line interactions by tissue of origin or cancer subtype. DCB is an open source Web-based tool that is freely available at: http://www.maayanlab.net/LINCS/DCB CONTACT: avi.maayan@mssm.edu Supplementary data are available at Bioinformatics online. © The Author 2014.

Derksen, Frans; Bensing, Jozien; Lagro-Janssen, Antoine

2012-01-01

Background Empathy as a characteristic of patient–physician communication in both general practice and clinical care is considered to be the backbone of the patient–physician relationship. Although the value of empathy is seldom debated, its effectiveness is little discussed in general practice. This literature review explores the effectiveness of empathy in general practice. Effects that are discussed are: patient satisfaction and adherence, feelings of anxiety and stress, patient enablement, diagnostics related to information exchange, and clinical outcomes. Aim To review the existing literature concerning all studies published in the last 15 years on the effectiveness of physician empathy in general practice. Design and setting Systematic literature search. Method Searches of PubMed, EMBASE, and PsychINFO databases were undertaken, with citation searches of key studies and papers. Original studies published in English between July 1995 and July 2011, containing empirical data about patient experience of GPs’ empathy, were included. Qualitative assessment was applied using Giacomini and Cook’s criteria. Results After screening the literature using specified selection criteria, 964 original studies were selected; of these, seven were included in this review after applying quality assessment. There is a good correlation between physician empathy and patient satisfaction and a direct positive relationship with strengthening patient enablement. Empathy lowers patients’ anxiety and distress and delivers significantly better clinical outcomes. Conclusion Although only a small number of studies could be used in this search, the general outcome seems to be that empathy in the patient–physician communication in general practice is of unquestionable importance.

Determinants of an urban origin student choosing rural practice: a scoping review.

PubMed

Myhre, Douglas L; Bajaj, Sameer; Jackson, Wesley

2015-01-01

The shortage of physicians in rural and remote communities is an ongoing problem. Many studies have shown that the rural background of a student (ie rural origin) is a primary factor in recruiting physicians for practice in rural communities. Scoping reviews are primarily done to gauge the extent of literature on the research question at hand, typically with an intent that future research in that area is a constructive addition to pre-existing knowledge. This scoping review focuses on factors that predispose urban-origin students to choose a carrier in rural medicine. The study used Arksey and O'Malley's guidelines for a scoping review of the literature, which, in contrast to a traditional systematic review, is brief yet comprehensive. Medline (Ovid) and PubMed databases were used to review literature published between 1 January 1970 and 30 November 2014. After removing duplicates, articles were screened based on inclusion and exclusion criteria set up by the research team. The literature search resulted in 435 articles, 418 of which were excluded, leaving 17 articles for comprehensive review. Out of these 17 studies, the following four factors that suggest why urban-origin medical students may choose rural practice were generated: geographic diffusion of physicians in response to economic forces such as debt repayment and financial incentives (five studies), scope of practice and personal satisfaction (five studies), undergraduate and postgraduate rural training (nine studies) and premedical school mindset to practice rurally (five studies). Urban-origin students may choose rural practice because of market forces as well as financial incentives. The participation in undergraduate and postgraduate rural training is reported to positively alter the attitude of urban-origin students. A small subset of these students has a predetermined mindset to practice rurally at the time of matriculation. Obstacles for choosing a rural carrier include, but are not limited to lack of job and education opportunities for spouses/partners, lack of recreational and educational opportunities for children, and obscure opportunities for continuing medical education.

Theoretical domains framework to assess barriers to change for planning health care quality interventions: a systematic literature review.

Theoretical domains framework (TDF) provides an integrative model for assessing barriers to behavioral changes in order to suggest interventions for improvement in behavior and ultimately outcomes. However, there are other tools that are used to assess barriers. The objective of this study is to determine the degree of concordance between domains and constructs identified in two versions of the TDF including original (2005) and refined version (2012) and independent studies of other tools. We searched six databases for articles that studied barriers to health-related behavior changes of health care professionals or the general public. We reviewed quantitative papers published in English which included their questionnaires in the article. A table including the TDF domains of both original and refined versions and related constructs was developed to serve as a reference to describe the barriers assessed in the independent studies; descriptive statistics were used to express the results. Out of 552 papers retrieved, 50 were eligible to review. The barrier domains explored in these articles belonged to two to eleven domains of the refined TDF. Eighteen articles (36%) used constructs outside of the refined version. The spectrum of barrier constructs of the original TDF was broader and could meet the domains studied in 48 studies (96%). Barriers in domains of "environmental context and resources", "beliefs about consequences", and "social influences" were the most frequently explored in 42 (84%), 37 (74%), and 33 (66%) of the 50 articles, respectively. Both refined and original TDFs cataloged barriers measured by the other studies that did not use TDF as their framework. However, the original version of TDF explored a broader spectrum of barriers than the refined version. From this perspective, the original version of the TDF seems to be a more comprehensive tool for assessing barriers in practice.

Glioma is the most common intracranial tumor and has a poor patient prognosis. The presence of brain tumor stem cells was gradually being understood and recognized, which might be beneficial for the treatment of glioma. To use bibliometric indexes to track study focuses on glioma stem cell, and to investigate the relationships among geographic origin, impact factors, and highly cited articles indexed in Web of Science. A list of citation classics for glioma stem cells was generated by searching the database of Web of Science-Expanded using the terms "glioma stem cell" or "glioma, stem cell" or "brain tumor stem cell". The top 63 cited research articles which were cited more than 100 times were retrieved by reading the abstract or full text if needed. Each eligible article was reviewed for basic information on subject categories, country of origin, journals, authors, and source of journals. Inclusive criteria: (1) articles in the field of glioma stem cells which was cited more than 100 times; (2) fundamental research on humans or animals, clinical trials and case reports; (3) research article; (4) year of publication: 1899-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles needing to be manually searched or accessed only by telephone; (2) unpublished articles; and (3) reviews, conference proceedings, as well as corrected papers. Of 2 040 articles published, the 63 top-cited articles were published between 1992 and 2010. The number of citations ranged from 100 to 1 754, with a mean of 280 citations per article. These citation classics came from nineteen countries, of which 46 articles came from the United States. Duke University and University of California, San Francisco led the list of classics with seven papers each. The 63 top-cited articles were published in 28 journals, predominantly Cancer Research and Cancer Cell, followed by Cell Stem Cell and Nature. Our bibliometric analysis provides a historical perspective on the progress of glioma stem cell research. Articles originating from outstanding institutions of the United States and published in high-impact journals are most likely to be cited.

We previously reviewed evidence published from 1992 to 2001 concerning early experience for healthcare undergraduates (Dornan T, Littlewood S, Margolis S, Scherpbier A, Spencer J, Ypinazar V. 2006. How can experience in clinical and community settings contribute to early medical education? A BEME systematic review. Med Teach 28:3-18). This subsequent study reviews evidence published from 2002 to 2008. Identify changes in the evidence base; determine the value of re-reviewing; set a future research agenda. The same search strategy as in the original review was repeated. Newly identified publications were critically appraised against the same benchmarks of strength and educational importance. Twenty-four new empirical studies of early authentic experience in education of health professionals met our inclusion criteria, yielding 96 outcomes. Sixty five outcomes (from 22 studies) were both educationally important and based on strong evidence. A new significant theme was found: the use of early experience to help students understand and align themselves with patient and community perspectives on illness and healthcare. More publications were now from outside Europe and North America. In addition to supporting the findings of our original review, this update shows an expansion in research sources, and a shift in research content focus. There are still questions, however, about how early authentic experience leads to particular learning outcomes and what will make it most educationally effective.
