The NASA-ADS Abstract Service provides a sophisticated search capability for the literature in Astronomy, Planetary Sciences, Physics/Geophysics, and Space Instrumentation. The ADS is funded by NASA and access to the ADS services is free to anybody worldwide without restrictions. It allows the user to search the literature by author, title, and abstract text. The ADS database contains over 3.6 million references, with 965,000 in the Astronomy/Planetary Sciences database, and 1.6 million in the Physics/Geophysics database. 2/3 of the records have full abstracts, the rest are table of contents entries (titles and author lists only). The coverage for the Astronomy literature is better than 95% from 1975. Before that we cover all major journals and many smaller ones. Most of the journal literature is covered back to volume 1. We now get abstracts on a regular basis from most journals. Over the last year we have entered basically all conference proceedings tables of contents that are available at the Harvard Smithsonian Center for Astrophysics library. This has greatly increased the coverage of conference proceedings in the ADS. The ADS also covers the ArXiv Preprints. We download these preprints every night and index all the preprints. They can be searched either together with the other abstracts or separately. There are currently about 260,000 preprints in that database. In January 2004 we have introduced two new services, full text searching and a personal notification service called "myADS". As all other ADS services, these are free to use for anybody.

Stakeholders' Perspectives on Preclinical Testing for Alzheimer's Disease.

Arias, Jalayne J; Cummings, Jeffrey; Grant, Alexander Rae; Ford, Paul J

2015-01-01

Progress towards validating amyloid beta as an early indicator of Alzheimer's disease (AD) heightens the need for evaluation of stakeholders' perspectives of the benefits and harms of preclinical testing in asymptomatic individuals. Investigators conducted and analyzed 14 semi-structured interviews with family members of patients diagnosed with AD. Participants reported benefits, including the potential to seek treatment, make lifestyle changes, and prepare for cognitive impairment. Participants identified harms, including social harms, adverse life decisions, and psychological harms. Nine participants reported either a "positive global perspective" or a "positive global perspective (qualified)." Results from this study characterized stakeholders' perspectives on the potential benefits and harms of clinical use of preclinical testing for AD. Investigators used data from this study to develop a framework that contributes to ongoing discussions that will evaluate widespread adoption of preclinical testing and will inform future research.

Scientific feuds, polemics, and ad hominem arguments in basic and special-interest genetics.

PubMed

Carlson, Elof Axel

Scientific disputes are commonly presented and settled in journal publications. Most are resolved by a weighing of evidence and new findings. In some cases the arguments are personal and in the form of ad hominem attacks on the personality or integrity of an author of a journal article. Many famous scientists (e.g., Galileo, Newton, and Hooke) used ad hominem arguments in responding to their critics. William Bateson, W.F.R. Weldon, William Castle, and H.J. Muller used ad hominem arguments in their publications until the end of World War I, when editorial policy of journals changed. Motivating some of the attacks are philosophic differences (such as holistic or reductionist approaches to science), ideological differences (such as Marxist or Capitalist outlooks), politics (such as Cold War depictions by East and West on fallout from nuclear testing), or conflicts of interest (which can be professional or financial such as the debates over nontraditional and orthodox medicine or over tobacco smoking and health). Most of the time, the disputes are motivated by honest disagreements over the interpretation of the data. A recent surge (2009-2016) of ad hominem attacks by Edward Calabrese has appeared disparaging H. J. Muller, E. B. Lewis, other twentieth-century contributors to radiation genetics, and the National Academy of Sciences. They address the mutational effects of low-dose radiation exposure. Calabrese's attacks have led to responses by geneticists in the field of mutagenesis, by agencies criticized by Calabrese, and by students and colleagues of those who have been accused of deception by Calabrese. This article reviews some of the history of ad hominem arguments in science and the background to the attacks by Calabrese. I argue that Calabrese's characterization of Muller and his supporters is unjust, misleading, and hurtful. I also propose some methods for dealing with or preventing ad hominem attacks in professional journals. Copyright © 2017. Published by Elsevier B.V.

Suppression bias at the Journal of Occupational and Environmental Medicine.

PubMed

Egilman, David S

2005-01-01

When the Journal of Occupational and Environmental Medicine rejected an article on corporate suppression of science on the grounds that the topic "was not a high priority" for journal readers, the author bought advertising space in JOEM to present his findings. The JOEM editor regretted he had not seen the ad to prevent its publication, and subsequently allowed the corporate-sponsored authors of a criticized study to respond to the advertisement. The editor then refused to allow the ad's author to respond in turn, suppressing scientific information with the apparent intent of protecting the interests and profits of the corporate sponsor. A reputable journal has a responsibility to eschew corporate interests and work to uncover science hidden by interests that do not prioritize the pursuit of truth. JOEM needs to re-examine its priorities.

In the last few months the data holdings in the ADS have been considerably expanded. In the abstracts databases we have included over 50,000 abstracts from SPIE conference proceedings (provided by SPIE), a complete set of references for lunar and planetary sciences, and abstracts from recent Lunar and Planetary Institute sponsored conferences (both provided by the Lunar and Planetary Institute). We also extended our cooperation with the CDS in Strasbourg, France by providing a link to the list of objects that are in the SIMBAD database for each reference. The ADS article service now holds full-text articles for 20 years of the Astrophysical Journal Letters, the Astronomical Journal, and the Publications of the Astronomical Society of the Pacific, and 5 years of the Astrophysical Journal on-line. The following journals are being processed and some may be on-line for this AAS meeting: Astrophysical Journal (1975-1989), Astronomy and Astrophysics, Proceedings of the Astronomical Society of Australia, Publications of the Astronomical Society of Japan, Revista Mexicana, Bulletin of the Astronomical Society of India, Obs. Reports of Skalnate Pleso, and Baltic Astronomy. We are now working with two scanning companies to speed up the scanning process and hope that by the end of the year we have all of these journals completely on-line for at least the period 1975 - 1995.

Planetary Sciences Literature - Access and Discovery

NASA Astrophysics Data System (ADS)

Henneken, Edwin A.; ADS Team

2017-10-01

The NASA Astrophysics Data System (ADS) has been around for over 2 decades, helping professional astronomers and planetary scientists navigate, without charge, through the increasingly complex environment of scholarly publications. As boundaries between disciplines dissolve and expand, the ADS provides powerful tools to help researchers discover useful information efficiently. In its new form, code-named ADS Bumblebee (https://ui.adsabs.harvard.edu), it may very well answer questions you didn't know you had! While the classic ADS (http://ads.harvard.edu) focuses mostly on searching basic metadata (author, title and abstract), today's ADS is best described as a an "aggregator" of scholarly resources relevant to the needs of researchers in astronomy and planetary sciences, and providing a discovery environment on top of this. In addition to indexing content from a variety of publishers, data and software archives, the ADS enriches its records by text-mining and indexing the full-text articles (about 4.7 million in total, with 130,000 from planetary science journals), enriching its metadata through the extraction of citations and acknowledgments. Recent technology developments include a new Application Programming Interface (API), a new user interface featuring a variety of visualizations and bibliometric analysis, and integration with ORCID services to support paper claiming. The new ADS provides powerful tools to help you find review papers on a given subject, prolific authors working on a subject and who they are collaborating with (within and outside their group) and papers most read by by people who read recent papers on the topic of your interest. These are just a couple of examples of the capabilities of the new ADS. We currently index most journals covering the planetary sciences and we are striving to include those journals most frequently cited by planetary science publications. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A.

Context Memory in Alzheimer's Disease: The "Who, Where, and When".

PubMed

El Haj, Mohamad; Antoine, Pascal

2018-03-01

Context memory, a component of episodic system, refers to the ability to retrieve conditions under which an event has occurred, such as who was present during that event and where and when it occurred. Context memory has been found to be compromised in older adults, an issue that we investigated in Alzheimer's disease (AD). Thirty-one participants with AD and 35 older adults were asked to generate three autobiographical events. Afterward, they were asked to remember the names of all people who were evoked during the events, and the names for any location that was mentioned during the events. Participants were also asked to remember the year, season, month and day of the week when the events occurred. Compared to older adults, participants with AD showed lower memory for "who" (p < .001), "where" (p < .05), and "when" (p < .01). Compared to "who" and "where", both participants with AD and older adults showed pronounced difficulties in remembering the "when". these findings highlight difficulties in remembering temporal information as an indication of context memory decline in AD. The difficulties in retrieving temporal information are discussed in terms of timing failures and hippocampal degenerations in AD. © The Author 2017. Published by Oxford University Press.

To determine whether neuropsychiatric symptoms (NPSs) are adequately considered in clinical research on Alzheimer's disease (AD). Systematic review. Randomized controlled trials (RCTs) recruiting individuals with AD and published during the last 10 years in 16 major general medicine, neurology, psychiatry, and geriatric psychiatry journals and RCTs registered on clinicaltrials.gov and currently enrolling individuals with AD. Individuals with AD. Outcome measures adopted by the included studies. Only 21.4% of the included studies identified through the bibliographic searches had measures of NPSs as a primary outcome. Only 17.7% of the studies retrieved on clinicaltrials.gov made a specific effort to test the effect of pharmacological or nonpharmacological interventions on NPSs. These findings show how rarely previous and current research on AD has considered NPSs as primary research targets. Although these symptoms are widely recognized as the most-stressful and -challenging manifestations of dementia, they are addressed much less often than other research targets. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

New Features in the ADS Abstract Service

Eichhorn, G.; Accomazzi, A.; Grant, C. S.; Kurtz, M. J.; ReyBacaicoa, V.; Murray, S. S.

2001-11-01

The ADS Abstract Service contains over 2.3 million references in four databases: Astronomy/Astrophysics/Planetary Sciences, Instrumentation, Physics/Geophysics, and Preprints. We provide abstracts and articles free to the astronomical community for all major and many smaller astronomy journals, PhD theses, conference proceedings, and technical reports. These four databases can be queried either separately of jointly. The ADS also has scanned 1.3 million pages in 180,000 articles in the ADS Article Service. This literature archive contains all major Astronomy journals and many smaller journals, as well as conference proceedings, including the abstract books from all the LPSCs back to volume 2. A new feature gives our users the ability to see list of articles that were also read by the readers of a given article. This is a powerful tool to find out what current articles are relevant in a particular field of study. We have recently expanded the citation and reference query capabilities. It allows our users to select papers for which they want to see references or citations and then retrieve these citations/references. Another new capability is the ability to sort a list of articles by their citation count. As usual, users should be reminded that the citations in ADS are incomplete because we do not obtain reference lists from all publishers. In addition, we cannot match all references (e.g. in press, private communications, author errors, some conference papers, etc.). Anyone using the citations for analysis of publishing records should keep this in mind. More work on expanding the citation and reference features is planned over the next year.

2006-12-01

The ADS is the search system of choice for the astronomical community. It also covers a large part of the physics and physics/astronomy education literature. In order to make access to this system as easy as possible, we developed a Google-like interface version of our search form. This one-field search parses the user input and automatically detects author names and year ranges. Firefox users can set up their browser to have this search field installed in the top right corner search field to have even easier access to the ADS search capability. The basic search is available from the ADS Homepage at: http://adsabs.harvard.edu To aid with access to subscription journals the ADS now supports OpenURL linking. If your library supports an OpenURL server, you can specify this server in the ADS preference settings. All links to journal articles will then automatically be directed to the OpenURL with the appropriate link information. We provide a selection of known OpenURL servers to choose from. If your server is not in this list, please send the necessary information to ads@cfa.harvard.edu and we will include it in our list. The ADS is funded by NASA grant NNG06GG68G.

This will replace the Preparations for the APS and LPSC meetings in March started. We will have demonstrations at both meetings. Preparations for the APS and LPSC meetings in March continued. We will have demonstrations at both meetings. The ADS was represented with a poster at the joint AGUEGU meeting in Nice, France. Discussions about the on-going collaboration between the ADS and the CDS in Strasbourg, France were held in Strasbourg. The ADS was invited to organize a session about the ADS and its mirror sites at the next United Nations Workshop on Basic Space Sciences in the Developing World. Efforts are under way to enter the tables of contents of all conference proceedings in the SA0 library into the ADS. This requires copying the tables of contents from all volumes in the library and have them typed in. This will greatly enhance the coverage of the literature in the ADS. We started the development of a search system for the full text of all scanned material in the ADS. This will eventually allow our users search capabilities that so far do not exist in any form. I order to enable the full text searching, we have purchased OCR software and are in the process of OCRing the scanned pages in the ADS. Efforts are in progress to handle the inclusion of data set identifiers in article manuscripts. The ADS will be the central system that will allow the journals to verify data set identifiers. The "master verifier" has been implemented in prototype form at the ADS. We started to include more journals in Geosciences/Geophysics in the ADS. The Royal astronomical Society has decided to archive their on-line journals in the ADS three years after publication. We have started to process these older on-line articles in order to archive them in the ADS. Our mirror site in Korea now has a full article mirror. We developed XML output capability in the ADS. This will make it easier to exchange data with other data systems. We started the development of new indexing software that will eventually reduce the indexing time for a database from days to hours or less. The ADS was represented at the IAU General Assembly with a poster. Discussions with the IAU management were held about extending the ADS IAU collaborations.

The Journal of Assisted Reproduction and Genetics introduces the JARG Young Investigator Forum, an in-training initiative aimed to expand opportunities for young investigators. The JARG Young Investigator Forum has three primary goals: first, to increase opportunities for trainees and young investigators to contribute as researchers and writers. Trainees will be invited to publish mini-reviews based on their area of research interest/expertise and will have the opportunity to indicate "in-training" when submitting manuscripts as first author Educational research pertaining to reproductive medicine training will be added to the purview of the journal. Second, the Young Investigator Forum will increase opportunities for trainees to serve as journal reviewers and will provide mentorship throughout the peer review process. Third, trainees will have the unique opportunity to gain editorial experience by serving as a "guest editor" of the Young Investigator Forum, overseeing all editorial aspects of their assigned particular issue. Through authorship, peer review, and editorial experience, we seek to nurture the academic skills that are critical to a well-rounded career. The JARG Young Investigator Forum aims to foster career development for a generation of trainees who represent the future of reproductive medicine, and here, we outline the primary goals and objectives of the initiative.

PubMed

1998-01-01

The ideal biomarker for Alzheimer's disease (AD) should detect a fundamental feature of neuropathology and be validated in neuropathologically-confirmed cases; it should have a sensitivity >80% for detecting AD and a specificity of >80% for distinguishing other dementias; it should be reliable, reproducible, non-invasive, simple to perform, and inexpensive. Recommended steps to establish a biomarker include confirmation by at least two independent studies conducted by qualified investigators with the results published in peer-reviewed journals. Our review of current candidate markers indicates that for suspected early-onset familial AD, it is appropriate to search for mutations in the presenilin 1, presenilin 2, and amyloid precursor protein genes. Individuals with these mutations typically have increased levels of the amyloid Abeta42 peptide in plasma and decreased levels of APPs in cerebrospinal fluid. In late-onset and sporadic AD, these measures are not useful, but detecting an apolipoprotein E e4 allele can add confidence to the clinical diagnosis. Among the other proposed molecular and biochemical markers for sporadic AD, cerebrospinal fluid assays showing low levels of Abeta42 and high levels of tau come closest to fulfilling criteria for a useful biomarker.

Hedl, J J; Glazer-Waldman, H R; Parker, H J; Hopkins, K M

1991-01-01

Using US Department of Defense text sampling procedures, nine allied health journals were analyzed for readability and selected writing style indices via Right Writer, a commercial software program. Two indices of readability were computed for each journal as were several indices of writing style. The computed readability ranged from 13.0 to 15.4, depending upon the journal in question. Two journals showed the highest levels of readability (15.4) compared to the other seven journals. The writing style analyses indicated generally normal ranges for the descriptive and jargon indices, but seven journals showed below recommended strength indices. Sentence structure analyses indicated a need to reduce sentence structure complexity. Implications for journal editors and authors are discussed.

1997-12-01

The Astrophysics Data System at http://adswww.harvard.edu is in the process of scanning the historical astronomical literature and making it available through the World Wide Web. We have scanned several volumes from the early 1800's of the "Astronomische Nachrichten", and the "Monthly Notices of the Royal Astronomical Society", the two oldest astronomical journals. We also have several of the early volumes of the "Astrophysical Journal" and the "Astronomical Journal" available. For all the journals that we cover, we have scanned volume 1. These early volumes can be accessed on a page-by-page basis. We plan to continue to scan this historical literature and complete these journals within the next year. We are also collaborating with a preservation project at Harvard University. This project will microfilm selected parts of astronomical Observatory reports. We plan to scan these microfilms to produce electronic images of these reports and put them on-line in the ADS. We hope to eventually cover most of the astronomical literature. In order to organize the scanned pages into articles, we need tables of contents (ToC). The early issues of the journals did not have printed ToC pages, so this needs to be done by hand. We do not have the financial resources to build these ToCs. We are looking for collaborators who would be willing to work with us in building these ToCs for the older journals and observatory reports. If you are interested in such a project, please contact the first author at gei@cfa.harvard.edu.

Impact Factor (IF) as a major journal quality indicator has a series of shortcomings including effect of self-citation, review articles, total number of articles, etc. In this study, we compared 4 journals quality indices ((IF), Eigenfactor Score (ES), Article Influence Score (AIS) and SCImago Journal Rank indicator (SJR)) in the specific Pediatric Neurology journals. All ISI and Scopus indexed specific Pediatric Neurology journals were compared regarding their 2011 IF, ES, AIS and SJR. Fourteen pediatric Neurology journals were identified, 3 of which were only Scopus indexed and the others were both ISI and Scopus indexed. High correlation was found between IF and AIS (0.850). Correlations between IF and other indices were not that high. Self-citation, total article number and review articles were related to the IF and other indices as well as their ranks. English language and citation to non citable item didn't have any effect on pediatric neurology journals ranks. Although all the above mentioned indicators can be used interchangeably, using all considered indices is a more appropriate way than using only IF for quality assessment of pediatric neurology journals.

Sex bias in psychoactive drug advertisements.

PubMed

King, E

1980-05-01

A recent concern has been the possible effect of sex-role stereotypes upon physicians' prescription patterns. In an attempt to examine the part played by drug advertisements, this paper will present a content analysis of psychoactive (mood-modifying) drug ads appearing in the American Journal of Psychiatry over a 17-year period; and a study of subjects' perceptions of the patients depicted in these drug ads across eight dimensions emerging from the content analysis. An initial perusal of psychoactive drug ads in professional medical journals suggested the existence of a sex bias: Females appeared to be presented as patients more often than males, and in a much more demeaning manner. The present analyses were done in an attempt to discover if a sex bias does exist in drug advertisements, which may influence the physician's perception of his or her patients, and subsequently, his or her prescription patterns.

2012-10-01

In the present paper, the authors make a bibliometrics study on clinical indications of acupuncture therapy based on the published foreign articles about acupuncture clinical trials collected from PubMed database and Excerpta Medica database (EMbase). In 1996, 64 acupuncture indications were declared by WHO in Milan conference. But in recent 15 years, clinical trials have been conducted extensively in the foreign countries. Till now, 77 new indications for acupuncture therapy have been found in the foreign journals. The authors recommended that 29 indications (knee osteoarthritis, critique age problems, muscular fasciae ache, anxiety, etc.) should be added to the first class, 4 indications (irritable bowel syndrome, malposition, backache, simple obesity) should be upgraded from the second class to the first class, and the other 3 indications (childbirth pain, male and female barren) should be upgraded from the third class to the first class due to their application frequency in clinical trials. Increase of clinical indications reflects extensive application of acupuncture therapy and may help providing a better service for people's health.

The role of the ADS in software discovery and citation

NASA Astrophysics Data System (ADS)

Accomazzi, Alberto

2018-01-01

As the primary index of scholarly content in astronomy and physics, the NASA Astrophysics Data System (ADS) is collaborating with the AAS journals and the Zenodo repository in an effort to promote the preservation of scientific software used in astronomy research and its citation in scholarly publications. In this talk I will discuss how ADS is updating its service infrastructure to allow for the publication, indexing, and citation of software records in scientific articles.

Taylor, Mary K

2006-04-01

Pediatric nurses work in an interdisciplinary field and face ever-increasing demands on their time and knowledge. Selection tools for librarians serving this group are available, but only one bibliometric analysis has examined citations to aid collection development. The "Mapping the Literature of Nursing Project" protocol was used. Three source journals were selected, and a citation analysis of articles from 1998 to 2000 was conducted. The frequency of journal citation was tabulated, and a list of the most frequently cited journals was created. Just over 1% of the cited journals produced 33% of the citations. PubMed/MEDLINE, Science Citation Index, and Social Sciences Citation Index provided the most complete indexing coverage of all types of the journals, while CINAHL providing the most complete coverage of nursing journals. Books were the second-most frequently cited format. Citation analysis of journal articles from pediatric nursing journals may be helpful in selecting journals for libraries serving pediatric nurses and those who conduct pediatric nursing research. Librarians should consider adding indexes to their collection in addition to PubMed/MEDLINE to access the broad range of journals useful to this specialty.

Alpinia intermedia, a perennial plant that belongs to the Zingiberaceae family, has been used in folk medicine for a long time in the southern region of Japan. Because skin care is an effective approach that enables patients to manage their atopic dermatitis (AD), various herbal ingredients with few adverse effects have been evaluated for use in AD patients in recent years. In this study, we examined whether distilled extracts obtained from A. intermedia were beneficial for AD-like skin conditions in NC/Tnd mice. Topical application with the A. intermedia extracts significantly reduced the severity of AD, transepidermal water loss and scratching behavior in the mice. Supplementation of the extracts to cell cultures suppressed the expression of Tslp mRNA in PAM212 keratinocytes, degranulation in bone marrow-derived cultured mast cells (BMCMC), and neurite outgrowth in PC12 cells and dorsal root ganglia. In addition, the component analysis revealed that β-pinene was a major constituent of the A. intermedia extracts. The inhibitory effects of β-pinene both in vivo and in vitro were also demonstrated. These results indicate that topical application with the A. intermedia extract to the skin of NC/Tnd mice improved the condition of the skin by suppressing multiple inflammatory responses. The extracts may become novel skin-care remedies for AD patients. © 2017 The Authors.

This supplement to the Journal of Alzheimer's Disease contains more than half of the chapters from The Handbook of Imaging the Alzheimer Brain, which was first presented at the International Conference on Alzheimer's Disease in Paris, in July, 2011. While the Handbook contains 27 chapters that are modified articles from 2009, 2010, and 2011 issues of the Journal of Alzheimer's Disease, this supplement contains the 31 new chapters of that book and an introductory article drawn from the introductions to each section of the book. The Handbook was designed to provide a multilevel overview of the full field of brain imaging related to Alzheimer's disease (AD). The Handbook, as well as this supplement, contains both reviews of the basic concepts of imaging, the latest developments in imaging, and various discussions and perspectives of the problems of the field and promising directions. The Handbook was designed to be useful for students and clinicians interested in AD as well as scientists studying the brain and pathology related to AD. PMID:21971448

Measuring biogeochemical responses to pulses of water

NASA Astrophysics Data System (ADS)

Balcerak, Ernie

2012-05-01

Hydrologic pulses, temporary increases in water inputs such as bouts of precipitation, can affect biogeochemical processes in ecosystems by providing water and nutrient resources. However, ecosystem responses to the water vary. Harms and Grimm conducted experiments to determine how hydrologic pulses and existing moisture conditions interact to affect the biogeochemistry of desert floodplains. During dry and monsoon seasons at their study site in the floodplains of the San Pedro River in Arizona, the researchers experimentally added pulses of water and then measured emissions of several trace gases that are indicators of biological processes. They found that the size of the added hydrologic pulse strongly interacted with existing soil moisture conditions in determining emissions of some trace gases. For instance, following dry conditions, pulses of water stimulated carbon dioxide, methane, and nitric oxide emissions, with larger water pulses stimulating more emissions. However, when soil was already wet, the addition of water pulses had less effect on the emission of these gases. (Journal of Geophysical Research-Biogeosciences, doi:10.1029/2011JG001775, 2012)

Alzheimer's disease (AD) is characterized by the aggregation and deposition of amyloid β protein (Aβ) in the brain. Soluble Aβ oligomers are thought to be toxic. To investigate the predominant species of Aβ protein that may play a role in AD pathogenesis, we performed biochemical analysis of AD and control brains. Sucrose buffer-soluble brain lysates were characterized in native form using blue native (BN)-PAGE and also in denatured form using SDS-PAGE followed by Western blot analysis. BN-PAGE analysis revealed a high-molecular weight smear (>1000 kD) of Aβ(42) -positive material in the AD brain, whereas low-molecular weight and monomeric Aβ species were not detected. SDS-PAGE analysis, on the other hand, allowed the detection of prominent Aβ monomer and dimer bands in AD cases but not in controls. Immunoelectron microscopy of immunoprecipitated oligomers and protofibrils/fibrils showed spherical and protofibrillar Aβ-positive material, thereby confirming the presence of high-molecular weight Aβ (hiMWAβ) aggregates in the AD brain. In vitro analysis of synthetic Aβ(40) - and Aβ(42) preparations revealed Aβ fibrils, protofibrils, and hiMWAβ oligomers that were detectable at the electron microscopic level and after BN-PAGE. Further, BN-PAGE analysis exhibited a monomer band and less prominent low-molecular weight Aβ (loMWAβ) oligomers. In contrast, SDS-PAGE showed large amounts of loMWAβ but no hiMWAβ(40) and strikingly reduced levels of hiMWAβ(42) . These results indicate that hiMWAβ aggregates, particularly Aβ(42) species, are most prevalent in the soluble fraction of the AD brain. Thus, soluble hiMWAβ aggregates may play an important role in the pathogenesis of AD either independently or as a reservoir for release of loMWAβ oligomers. © 2011 The Authors Journal of Cellular and Molecular Medicine © 2011 Foundation for Cellular and Molecular Medicine/Blackwell Publishing Ltd.

Highly polygenic architecture of antidepressant treatment response: Comparative analysis of SSRI and NRI treatment in an animal model of depression.

Response to antidepressant (AD) treatment may be a more polygenic trait than previously hypothesized, with many genetic variants interacting in yet unclear ways. In this study we used methods that can automatically learn to detect patterns of statistical regularity from a sparsely distributed signal across hippocampal transcriptome measurements in a large-scale animal pharmacogenomic study to uncover genomic variations associated with AD. The study used four inbred mouse strains of both sexes, two drug treatments, and a control group (escitalopram, nortriptyline, and saline). Multi-class and binary classification using Machine Learning (ML) and regularization algorithms using iterative and univariate feature selection methods, including InfoGain, mRMR, ANOVA, and Chi Square, were used to uncover genomic markers associated with AD response. Relevant genes were selected based on Jaccard distance and carried forward for gene-network analysis. Linear association methods uncovered only one gene associated with drug treatment response. The implementation of ML algorithms, together with feature reduction methods, revealed a set of 204 genes associated with SSRI and 241 genes associated with NRI response. Although only 10% of genes overlapped across the two drugs, network analysis shows that both drugs modulated the CREB pathway, through different molecular mechanisms. Through careful implementation and optimisations, the algorithms detected a weak signal used to predict whether an animal was treated with nortriptyline (77%) or escitalopram (67%) on an independent testing set. The results from this study indicate that the molecular signature of AD treatment may include a much broader range of genomic markers than previously hypothesized, suggesting that response to medication may be as complex as the pathology. The search for biomarkers of antidepressant treatment response could therefore consider a higher number of genetic markers and their interactions. Through predominately different molecular targets and mechanisms of action, the two drugs modulate the same Creb1 pathway which plays a key role in neurotrophic responses and in inflammatory processes. © 2016 The Authors.

From Excessive Journal Self-Cites to Citation Stacking: Analysis of Journal Self-Citation Kinetics in Search for Journals, Which Boost Their Scientometric Indicators.

Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science). We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics. Particularly in information science journals, the initial increase in a share of journal self-citations during post-publication year 0 was completely absent. Self-promoting journal self-citations of top-tier journals have rather indirect but negligible direct effects on bibliometric indicators, affecting just the immediacy index and marginally increasing the impact factor itself as long as the affected journals are well established in their fields. In contrast, other forms of journal self-citations and citation stacking may severely affect the impact factor, or other citation-based indices. We identified here a network consisting of three Romanian physics journals Proceedings of the Romanian Academy, Series A, Romanian Journal of Physics, and Romanian Reports in Physics, which displayed low to moderate ratio of journal self-citations, but which multiplied recently their impact factors, and were mutually responsible for 55.9%, 64.7% and 63.3% of citations within the impact factor calculation window to the three journals, respectively. They did not receive nearly any network self-cites prior impact factor calculation window, and their network self-cites decreased sharply after the impact factor calculation window. Journal self-citations and citation stacking requires increased attention and elimination from citation indices.

The NASA Astrophysics Data System: Overview

NASA Astrophysics Data System (ADS)

Kurtz, Michael J.; Eichhorn, Guenther; Accomazzi, Alberto; Grant, Carolyn S.; Murray, Stephen S.; Watson, Joyce M.

2000-04-01

The NASA Astrophysics Data System Abstract Service has become a key component of astronomical research. It provides bibliographic information daily, or near daily, to a majority of astronomical researchers worldwide. We describe the history of the development of the system and its current status. Urania (Boyce 1996), and the ADS role in the emerging electronic astronomical data environment are discussed. Astronomy is unique in that it already has a fully functional data resource, where several of the most important data sources exist on-line and inter-operate nearly seamlessly. The ADS and the Strasbourg Data Center (CDS; Genova et~al. 2000) form the core of this resource. We show several examples of how to use the ADS, and we show how ADS use has increased as a function of time. Currently it is still increasing exponentially, with a doubling time for number of queries of 17 months. Using the ADS logs we make the first detailed model of how scientific journals are read as a function of time since publication. We find four distinct components. We directly compare the readership rate with the citation rate for scientific articles as a function of age. Citations generally follow reads, but there are some differences. The main journals of astronomy have differences in the ways they are read and cited. We discuss these from a number of different aspects. The impact of the ADS on astronomy can be calculated after making some simple assumptions. We find that the ADS increases the efficiency of astronomical research by 333 Full Time Equivalent (2000 hour) research years per year, and that the value of the early development of the ADS for astronomy, compared with waiting for mature technologies to be adopted, is 2332 FTE research years. A full technical description of the ADS is in three companion articles: \\cite{gei}, \\cite{aa}, and \\cite{csg}. The ADS is available at http://adsabs.harvard.edu/.

EDITORIAL: Happy New Year!

As many of you are aware that Chinese science is at the crucial stage of development. We are now seeing more and more high quality works being produced by Chinese scientists working in China. However, high quality scientific works are rarely published in Chinese scientific journals so far. Therefore, the development of scientific journals publishing in China now becomes a more and more important indication of the science development in China. In the development of the chemical physics research field in China, the Chinese Journal of Chemical Physics (CJCP) has made significant contributions in the past 18 years. Since CJCP is primarily a Journal published in Chinese previously, its impact in the international scientific community has been quite limited. At this moment, we believe CJCP should increase its impact in the international community. We believe that making CJCP an English journal is a crucial step to increase its influence internationally. Therefore, upon the recommendation of senior editorial members, we now change CJCP into an full English journal from this issue on. We have also formed a high quality editorial board to help the editorial matters in CJCP, and a prestigious advisory board to advise us of the future development. I am very honored to be selected as the new Editor-in-Chief for the next four years. I hope by the end of my term, the impact of this journal is significantly improved through the efforts of our editorial team. Building a high quality scientific journal is not an easy task. I hope that every member of our chemical physics community can provide strong support to this journal by sending your high quality research papers in the future. We are also thinking about adding new sections of this journal to attract more readers. With the support of our community, I am confident that we can make this journal a more successful one. Here, I want to take this opportunity to thank the great leadership provided by the Editor-in-Chief since the foundation of this journal, Professor Nan-quan Lou, who has just become a senior advisory board member of this journal. I also want to thank the senior associate editor, Prof. Shu-qin Yu, who has made great contributions to the development of CJCP. Many thanks also go to the other senior associate editors, Profs. Die-yan Chen, Hai-lung Dai, Xing-xiao Ma, Han-qing Wang, Hou-wen Xin, Cun-hao Zhang and Qi-he Zhu, who have made important contributions to CJCP in the past 18 years. We plan that CJCP will soon become available online so that members of our community can access this journal easily through internet. This will also help us to provide greater visibility of this journal in the international research community.

It is well known that the occurrence of false memories increases with aging, but the results remain inconsistent concerning Alzheimer's disease (AD). Moreover, the mechanisms underlying the production of false memories are still unclear. Using an experimental episodic memory test with material based on the names of famous people in a procedure derived from the DRM paradigm [Roediger, H. L., III, & McDermott, K. B. (1995). Creating false memories: Remembering words not presented in lists. Journal of Experimental Psychology: Learning, Memory & Cognition, 21, 803-814], we examined correct and false recall and recognition in 30 young adults, 40 healthy older adults, and 30 patients with AD. Moreover, we evaluated the relationships between false memory performance, correct episodic memory performance, and a set of neuropsychological assessments evaluating the semantic memory and executive functions. The results clearly indicated that correct recall and recognition performance decreased with the subjects' age, but it decreased even more with AD. In addition, semantically related false recalls and false recognitions increased with age but not with dementia. On the contrary, non-semantically related false recalls and false recognitions increased with AD. Finally, the regression analyses showed that executive functions mediated related false memories and episodic memory mediated related and unrelated false memories in aging. Moreover, executive functions predicted related and unrelated false memories in AD, and episodic and semantic memory predicted semantically related and unrelated false memories in AD. In conclusion, the results obtained are consistent with the current constructive models of memory suggesting that false memory creation depends on different cognitive functions and, consequently, that the impairments of these functions influence the production of false memories.

Degree of free fatty acid saturation influences chocolate rejection in human assessors.

PubMed

Running, Cordelia A; Hayes, John E; Ziegler, Gregory R

2017-02-01

In foods, free fatty acids (FFAs) traditionally have been viewed as contributing an odor, yet evidence has accumulated that FFAs also contribute a unique taste ("oleogustus"). However, minimal work has been conducted using actual foods to test the contribution of FFA to taste preferences. Here, we investigate flavor, taste, and aroma contributions of added FFA in chocolate, as some commercial manufacturers already use lipolysis of triglycerides to generate unique profiles. We hypothesized that small added concentrations of FFAs would increase preferences for chocolate, whereas higher added concentrations would decrease preferences. We also hypothesized a saturated fatty acid (stearic C18) would have a lesser effect than a monounsaturated (oleic C18:1), which would have a lesser effect than a polyunsaturated (linoleic C18:2) fatty acid. For each, paired preference tests were conducted for 10 concentrations (0.04% to 2.25%) of added FFAs compared with the control chocolate without added FFAs. Stearic acid was tested for flavor (tasting and nares open), whereas the unsaturated fatty acids were tested for both aroma (orthonasal only and no tasting) and taste (tasting with nares blocked to eliminate retronasal odor). We found no preference for any added FFA chocolate; however, rejection was observed independently for both taste and aroma of unsaturated fatty acids, with linoleic acid reaching rejection at lower concentrations than oleic acid. These data indicate that degree of unsaturation influences rejection of both FFA aroma and taste in chocolate. Thus, alterations of FFA profiles in foods should be approached cautiously to avoid shifting concentrations of unsaturated fatty acids to hedonically unacceptable levels. © The Author 2016.

Asnafi, Solmaz; Gunderson, Tina; McDonald, Robert J; Kallmes, David F

2017-02-01

h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups. Among the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median. Our data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals. Copyright © 2017 The Association of University Radiologists.

The objective is to examine failure on three embedded performance validity tests [Reliable Digit Span (RDS), Auditory Verbal Learning Test (AVLT) logistic regression, and AVLT recognition memory] in early Alzheimer disease (AD; n = 178), amnestic mild cognitive impairment (MCI; n = 365), and cognitively intact age-matched controls (n = 206). Neuropsychological tests scores were obtained from subjects participating in the Alzheimer's Disease Neuroimaging Initiative (ADNI). RDS failure using a ≤7 RDS threshold was 60/178 (34%) for early AD, 52/365 (14%) for MCI, and 17/206 (8%) for controls. A ≤6 RDS criterion reduced this rate to 24/178 (13%) for early AD, 15/365 (4%) for MCI, and 7/206 (3%) for controls. AVLT logistic regression probability of ≥.76 yielded unacceptably high false-positive rates in both clinical groups [early AD = 149/178 (79%); MCI = 159/365 (44%)] but not cognitively intact controls (13/206, 6%). AVLT recognition criterion of ≤9/15 classified 125/178 (70%) of early AD, 155/365 (42%) of MCI, and 18/206 (9%) of control scores as invalid, which decreased to 66/178 (37%) for early AD, 46/365 (13%) for MCI, and 10/206 (5%) for controls when applying a ≤5/15 criterion. Despite high false-positive rates across individual measures and thresholds, combining RDS ≤ 6 and AVLT recognition ≤9/15 classified only 9/178 (5%) of early AD and 4/365 (1%) of MCI patients as invalid performers. Embedded validity cutoffs derived from mixed clinical groups produce unacceptably high false-positive rates in MCI and early AD. Combining embedded PVT indicators lowers the false-positive rate. © The Author 2016. Published by Oxford University Press. All rights reserved.

Covey, A M; Sunshine, J; Forman, H P

2000-10-01

The purpose of this article is to report 1999 data on the job market in diagnostic radiology detected using a help wanted index of job advertisements and to profile trends in practice type, location, and subspecialty using our previously published data as a basis for comparison. Each advertised job for a diagnostic radiologist in the American Journal of Roentgenology and RADIOLOGY: between January 1991 and December 1999 was coded by practice type, location, and subspecialty. In 1999, 3926 positions were advertised for diagnostic radiologists, representing a 75% increase from 1998. Private practice jobs, which represented 53% of advertisements from 1991 through 1994 and 64% of ads from 1995 through 1998, increased to 66% of ads in 1999. Geographic trends in 1999 were characterized by a relative increase of jobs in the Midwest and California and a decrease in percentage (but increase in total number of ads) in the Northeast and Southwest. The demand for subspecialists continued in 1999, with only 34% of ads placed for general radiologists. A relative increase in demand for neuroradiologists, mammographers, and abdominal imagers was also seen in 1999 in comparison with previously published data from 1995 through 1998. The demand for diagnostic radiologists continues to rise, with more ads placed in 1999 than any other year from 1991 through 1998. Using a help wanted index of job advertisements, we have created an indicator of changes in the diagnostic radiology job market with specific reference to practice type, geographic location, and subspecialty training.

Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on methanogenic archaea, duplicate laboratory-scale AD bioreactors were operated at 37°C followed by a temperature drop to 15°C. A volatile fatty acid-based wastewater (composed of propionic acid, butyric acid, acetic acid and ethanol) was used to provide substrates representing the later stages of AD. Community structure was monitored using 16S rRNA gene clone libraries, as well as DNA and cDNA-based DGGE analysis, while the abundance of relevant methanogens was followed using qPCR. In addition, metaproteomics, microautoradiography-fluorescence in situ hybridization, and methanogenic activity measurements were employed to investigate microbial activities and functions. Methanomicrobiales abundance increased at low temperature, which correlated with an increased contribution of CH4 production from hydrogenotrophic methanogenesis at 15°C. Methanosarcinales utilized acetate and H2/CO2 as CH4 precursors at both temperatures and a partial shift from acetoclastic to hydrogenotrophic methanogenesis was observed for this archaeal population at 15°C. An upregulation of protein expression was reported at low temperature as well as the detection of chaperones indicating that mesophilic communities experienced stress during long-term exposure to 15°C. Overall, changes in microbial community structure and function were found to underpin the adaptation of mesophilic sludge to psychrophilic AD. © FEMS 2015. All rights reserved.

A Website System for Communicating Psychological Science.

PubMed

Diener, Ed

2017-07-01

The peer review and journal system have shortcomings, and both computers and the Internet have made complementary or alternative systems attractive. In this article, I recommend that we implement a new platform for open communication of psychological science on a dedicated website to complement the current review and journal system, with reader reviews of the articles and with all behavioral scientists being eligible to publish and review articles. The judged merit of articles would be based on the citations and the ratings of the work by the whole scientific community. This online journal will be quicker, more democratic, and more informative than the current system. Although the details of the system should be debated and formulated by a committee of scientists, adding this online journal to the existing publications of a society such as the Association for Psychological Science has few risks and many possible gains. An online journal deserves to be tried and assessed.

Networking of Bibliographical Information: Lessons learned for the Virtual Observatory

NASA Astrophysics Data System (ADS)

Genova, Françoise; Egret, Daniel

Networking of bibliographic information is particularly remarkable in astronomy. On-line journals, the ADS bibliographic database, SIMBAD and NED are everyday tools for research, and provide easy navigation from one resource to another. Tables are published on line, in close collaboration with data centers. Recent new developments include the links between observatory archives and the ADS, as well as the large scale prototyping of object links between Astronomy and Astrophysics and SIMBAD, following those implemented a few years ago with New Astronomy and the International Bulletin of Variable stars . This networking has been made possible by close collaboration between the ADS, data centers such as the CDS and NED, and the journals, and this partnership being now extended to observatory archives. Simple, de facto exchange standards, like the bibcode to refer to a published paper, have been the key for building links and exchanging data. This partnership, in which practitioners from different disciplines agree to link their resources and to work together to define useful and usable standards, has produced a revolution in scientists' practice. It is an excellent model for the Virtual Observatory projects.

[Analysis of citations and national and international impact factor of Farmacia Hospitalaria (2001-2005)].

2007-01-01

The objective of this study is to analyse the citation patterns and impact and immediacy indicators of the Farmacia Hospitalaria journal during the period 2001-2005. An analysis of citations chosen from 101 Spanish health science journals was carried out in order to determine the citing and cited journals and the national and international impact and immediacy indicators. A similar methodology used by Thomson ISI in Science Citation Index (SCI) and Journal Citation Reports (JRC) was applied. Farmacia Hospitalaria made 1,370 citations to 316 different journals. The percentage of self-citations was 9%. The national impact factor increased from 0.178 points in 2001 to 0.663 points in 2005 while the international impact factor increased from 0.178 to 0.806 for the same period. The analysis of citation patterns demonstrates the multidisciplinary nature of Farmacia Hospitalaria and a significant growth in the impact indicators over recent years. These indicators are higher than those of some other pharmacy journals included in Journal Citation Reports. Self-citation was not excessive and was similar to that of other journals.

Dassa, Ayelet; Amir, Dorit

2014-01-01

Language deficits in people with Alzheimer's disease (AD) manifest, among other things, in a gradual deterioration of spontaneous speech. People with AD tend to speak less as the disease progresses and their speech becomes confused. However, the ability to sing old tunes sometimes remains intact throughout the disease. The purpose of this study was to explore the role of singing familiar songs in encouraging conversation among people with middle to late stage AD. Six participants attended group music therapy sessions over a one-month period. Using content analysis, we qualitatively examined transcriptions of verbal and sung content during 8 group sessions for the purpose of understanding the relationship between specific songs and conversations that occurred during and following group singing. Content analysis revealed that songs from the participants' past-elicited memories, especially songs related to their social and national identity. Analyses also indicated that conversation related to the singing was extensive and the act of group singing encouraged spontaneous responses. After singing, group members expressed positive feelings, a sense of accomplishment, and belonging. Carefully selecting music from the participants' past can encourage conversation. Considering the failure in spontaneous speech in people with middle to late stage AD, it is important to emphasize that group members' responses to each other occurred spontaneously without the researcher's encouragement. © the American Music Therapy Association 2014.

We evaluated the feasibility and reliability of commonly used clinical dementia assessments when administered via direct-to-home telemedicine videoconferencing. To date, few studies assessed the suitability of these measures when used in this setting. Sixty-six participants (33 patients with Alzheimer's disease (AD) and their 33 caregivers) consented to assessment with a battery of tests in both the clinic setting and via telemedicine. We administered cognitive, behavior, and mood assessments to persons with mild, moderate, and severe AD both in the clinic setting and via direct-to-home telemedicine videoconferencing; test-retest reliability was assessed. We also explored how three caregiver measures performed when administered via telemedicine. Assessments were administered 2 weeks apart. Participant feedback about their experience was solicited. Twenty-eight dyads completed the assessments. Reliability was found to be good to excellent in all measures when used with direct-to-home telemedicine. For the most part, participants and clinicians found telemedicine to be a feasible option for assessing cognitive function and caregiver coping. Findings indicate that these measures can be used to assess persons with AD, as well as their caregivers, across the telemedicine platform, directly to their homes. Use of this technology can expand access to care to the millions across the United States with AD and their caregivers. © The Author 2017.

Citations to articles published in academic journals represent a proxy for influence in bibliometrics. To measure the journal impact factor for Progress in Transplantation over time and to also identify related journals indexed in transplantation and surgery. Data from Journal Citation Reports (ISI web of science) were used to rank Progress in Transplantation compared to peer journals using journal impact and journal relatedness measures. Social network analysis was used to measure relationships between pairs of journals in Progress in Transplantation's relatedness network. Journal impact factor and journal relatedness. Data from 2010 through 2015 indicate the average journal article in PIT was cited 0.87 times (standard deviation [SD] = 0.12) and this estimate was stable over time. Progress in Transplantation most often cited American Journal of Transplantation, Transplantation, American Journal of Kidney Diseases, and Liver Transplantation. In terms of cited data, the journal was most often referenced by Clinical Transplantation, Transplant International, and Current Opinion in Organ Transplantation. The journal is listed both in surgery and transplantation categories of Journal Citation Reports and its impact factors over time fare better with surgery journals than with transplant journals. Network data using betweenness centrality indicate Progress in Transplantation links transplantation-focused journals and journals indexed in health sciences categories.

Effectiveness of Environment-Based Interventions That Address Behavior, Perception, and Falls in People With Alzheimer's Disease and Related Major Neurocognitive Disorders: A Systematic Review.

PubMed

Jensen, Lou; Padilla, René

This systematic review evaluated the effectiveness of environment-based interventions that address behavior, perception, and falls in the home and other settings for people with Alzheimer's disease (AD) and related major neurocognitive disorders (NCDs). Database searches were limited to outcomes studies published in English in peer-reviewed journals between January 2006 and April 2014. A total of 1,854 articles were initially identified, of which 42 met inclusion criteria. Strong evidence indicates that person-centered approaches can improve behavior. Moderate evidence supports noise regulation, environmental design, unobtrusive visual barriers, and environmental relocation strategies to reduce problematic behaviors. Evidence is insufficient for the effectiveness of mealtime ambient music, bright light, proprioceptive input, wander gardens, optical strategies, and sensory devices in improving behavior or reducing wandering and falls. Although evidence supports many environment-based interventions used by occupational therapy practitioners to address behavior, perception, and falls in people with AD and related major NCDs, more studies are needed.

Visibility of medical informatics regarding bibliometric indices and databases

PubMed Central

2011-01-01

Background The quantitative study of the publication output (bibliometrics) deeply influences how scientific work is perceived (bibliometric visibility). Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics. Methods By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices. Results The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong. Conclusions The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author-related indices enable an easy and adequate individual assessment. PMID:21496230

Altered cell cycle-related gene expression in brain and lymphocytes from a transgenic mouse model of Alzheimer's disease [amyloid precursor protein/presenilin 1 (PS1)].

Cumulative evidence indicates that aberrant re-expression of many cell cycle-related proteins and inappropriate neuronal cell cycle control are critical events in Alzheimer's disease (AD) pathogenesis. Evidence of cell cycle activation in post-mitotic neurons has also been observed in murine models of AD, despite the fact that most of these mice do not show massive loss of neuronal bodies. Dysfunction of the cell cycle appears to affect cells other than neurons, as peripheral cells, such as lymphocytes and fibroblasts from patients with AD, show an altered response to mitogenic stimulation. We sought to determine whether cell cycle disturbances are present simultaneously in both brain and peripheral cells from the amyloid precursor protein (APP)/presenilin 1 (PS1) mouse model of AD, in order to validate the use of peripheral cells from patients not only to study cell cycle abnormalities as a pathogenic feature of AD, but also as a means to test novel therapeutic approaches. By using cell cycle pathway-specific RT(2)Profiler™ PCR Arrays, we detected changes in a number of cell cycle-related genes in brain as well as in lymphocytes from APP/PS1 mice. Moreover, we found enhanced 5'-bromo-2'-deoxyuridine incorporation into DNA in lymphocytes from APP/PS1 mice, and increased expression of the cell proliferation marker proliferating cell nuclear antigen (PCNA), and the cyclin-dependent kinase (CDK) inhibitor Cdkn2a, as detected by immunohistochemistry in cortical neurons of the APP/PS1 mice. Taken together, the cell cycle-related changes in brain and blood cells reported here support the mitosis failure hypothesis in AD and validate the use of peripheral cells as surrogate tissue to study the molecular basis of AD pathogenesis. © 2012 The Authors.

Performance of Malaysian Medical Journals

PubMed Central

Abrizah, Abdullah

2016-01-01

Indexation status matters for scholarly journal prestige and trust. The performance of Malaysian medical journals at the international level is gauged through the global citation databases, and at the national level through MyCite, a national citation indexing system. The performance indicators include journals publication productivity, the citations they garner, and their scores on other bibliometric indices such as journal impact factor (IF), and h-index. There is a growing consciousness amongst journal editorials to improve quality and increase chances of getting indexed in MyCite. Although it is now possible to gauge journal performance within Malaysia, through MyCite, the government and public are concerned about journal performance in international databases. Knowing the performance of journals in MyCite will help the editors and publishers to improve the quality and visibility of Malaysian journals and strategise to bring their journal to the international level of indexation.

Objective To investigate the effectiveness of open peer review as a mechanism to improve the reporting of randomised trials published in biomedical journals. Design Retrospective before and after study. Setting BioMed Central series medical journals. Sample 93 primary reports of randomised trials published in BMC-series medical journals in 2012. Main outcome measures Changes to the reporting of methodological aspects of randomised trials in manuscripts after peer review, based on the CONSORT checklist, corresponding peer reviewer reports, the type of changes requested, and the extent to which authors adhered to these requests. Results Of the 93 trial reports, 38% (n=35) did not describe the method of random sequence generation, 54% (n=50) concealment of allocation sequence, 50% (n=46) whether the study was blinded, 34% (n=32) the sample size calculation, 35% (n=33) specification of primary and secondary outcomes, 55% (n=51) results for the primary outcome, and 90% (n=84) details of the trial protocol. The number of changes between manuscript versions was relatively small; most involved adding new information or altering existing information. Most changes requested by peer reviewers had a positive impact on the reporting of the final manuscript—for example, adding or clarifying randomisation and blinding (n=27), sample size (n=15), primary and secondary outcomes (n=16), results for primary or secondary outcomes (n=14), and toning down conclusions to reflect the results (n=27). Some changes requested by peer reviewers, however, had a negative impact, such as adding additional unplanned analyses (n=15). Conclusion Peer reviewers fail to detect important deficiencies in reporting of the methods and results of randomised trials. The number of these changes requested by peer reviewers was relatively small. Although most had a positive impact, some were inappropriate and could have a negative impact on reporting in the final publication. PMID:24986891

Unsuccessfully Treated Hypertension: A Major Public Health Problem With a Potential Solution.

PubMed

Furberg, Curt D; Sealey, Jean E; Blumenfeld, Jon D

2017-09-01

About one-half of all hypertensive adults do not have their blood pressure controlled. They are often prescribed medications that conform to national guidelines but they continue to have elevated blood pressure. This public health problem might be improved by applying plasma renin guided therapy. A contributor to the public health problem of unsuccessfully treated hypertension is that the circulating renin-angiotensin system (RAS) is not recognized in treatment guidelines as clinically relevant for the treatment of hypertension or as important as the body salt status for determining blood pressure levels. Another contributor to the problem is the lack of specificity in the package inserts for antihypertensive drugs. They do not specifically state under the heading "Indications" that RAS blockers are primarily most effective in hypertensive subjects with medium and high plasma renin levels; by contrast, natriuretic drugs are most effective in those with low plasma renin levels. Literature review. To address the problem of unsuccessfully treated hypertension, we recommend that the "Indications" section of package inserts for antihypertensive drugs be more specific. The primary indication for RAS blockers ought to be hypertension with medium and high plasma renin levels, and natriuretic agents for those with low plasma renin levels. Similar language ought to be added to treatment guidelines. Additionally, 3 other reasons for lack of blood pressure control also need to be addressed-failure to prescribe antihypertensive drugs to hypertensive subjects, failure of patients to fill prescriptions, and low drug adherence. © American Journal of Hypertension, Ltd 2017.

Framing narrative journalism as a new genre: A case study of the Netherlands.

PubMed

van Krieken, Kobie; Sanders, José

2017-11-01

Although narrative journalism has a long history in the Netherlands, it is in recent years being promoted as a 'new' genre. This study examines the motives underlying this promotional tactic. To that end, we analyze how narrative journalism is framed in (1) public expressions of the initiatives aimed at professionalization of the genre and (2) interviews with journalists and lecturers in journalism programs. Results indicate that in public discourse on narrative journalism, the genre is framed as moving , essential , and as high quality journalism . These frames indicate that the current promotion of narrative journalism as 'new' can be seen as a strategy that journalists apply to withstand the pressures they are facing in the competition with new media. These frames are deepened in the interviews with lecturers and practitioners, who frame narrative journalism as a dangerous game , a paradigm shift , and as the Holy Grail . These frames indicate that narrative journalism is regarded as the highest achievable goal for journalists, but that its practice comes with dangers and risks: it tempts journalists to abandon the traditional principles of objectivity and factuality, which can ultimately cause journalism to lose its credibility and authority. We discuss these findings in terms of boundary work and reflect on implications for narrative journalism's societal function.

Examination of the impact of animal and dairy science journals based on traditional and newly developed bibliometric indices.

Malesios, C; Abas, Z

2012-12-01

Using traditional bibliometric indices such as the well-known journal impact factor (IFAC), as well as other more recently developed measures like the (journal) h-index and modifications, we assessed the impact of most prolific scientific journals in the field of animal and dairy science. To achieve this end, we performed a detailed investigation on the evaluation of journals quality, using a total of 50 journals selected from the category of "Agriculture, Dairy & Animal Science" included in the Thomson Reuters' (formerly Institute of Scientific Information, ISI) Web of Science. Our analysis showed that among the top journals in the field are the Journal of Dairy Research, the Journal of Dairy Science, and the Journal of Animal Science. In particular, the Journal of Animal Science, the most productive and frequently cited journal, has shown rapid development, especially in recent years. The majority of the top-tier, highly cited articles are those associated with the description of statistical methodology and the standard chemical analytical methodologies.

Quantified trends in the history of verbal behavior research

PubMed Central

Eshleman, John W.

1991-01-01

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

Activate Omaha (AO), a community-wide health initiative, was awarded a grant by Active Living by Design in 2003. To establish credibility of the partners in AO and increase awareness of active living in the community by emphasizing promotions (branding, logo recognition). Media, including billboards, TV and radio ads, high-profile spokespersons, grassroots efforts, and worksite "toolkits" featuring tips and creative messaging on physical activity were combined to incentivize people to be physically active. Campaign surveys were conducted by the Market Survey Research Group each year from 2005 to 2008. Survey data based on the first campaign indicated that 86% of Omahans wanted to be part of an active community and to be active with younger generations. The second campaign focused on getting families physically active together, and this survey data showed that citizens wanted to be a part of an active community. A third campaign added practical examples of citizens being active within the community and efforts expanded to worksites with consistent messaging for employees. The final survey indicated that 78% of respondents found Omaha to be an active community compared to 63% who had that response 3 years earlier. Activate Omaha was successful in gaining credibility and leveraging additional funding to implement complementary programming and physical projects, and as a result, changing community perceptions and influencing policy decisions.

Cranberry Extract Standardized for Proanthocyanidins Alleviates β-Amyloid Peptide Toxicity by Improving Proteostasis Through HSF-1 in Caenorhabditis elegans Model of Alzheimer's Disease.

2016-12-01

A growing body of evidence suggests that nutraceuticals with prolongevity properties may delay the onset of Alzheimer's disease (AD). We recently demonstrated that a proanthocyanidins-standardized cranberry extract has properties that prolong life span and promote innate immunity in Caenorhabditis elegans In this article, we report that supplementation of this cranberry extract delayed Aβ toxicity-triggered body paralysis in the C elegans AD model. Genetic analyses indicated that the cranberry-mediated Aβ toxicity alleviation required heat shock transcription factor (HSF)-1 rather than DAF-16 and SKN-1. Moreover, cranberry supplementation increased the transactivity of HSF-1 in an IIS-dependent manner. Further studies found that the cranberry extract relies on HSF-1 to significantly enhance the solubility of proteins in aged worms, implying an improved proteostasis in AD worms. Considering that HSF-1 plays a pivotal role in maintaining proteostasis, our results suggest that cranberry maintains the function of proteostasis through HSF-1, thereby protecting C elegans against Aβ toxicity. Together, our findings elucidated the mechanism whereby cranberry attenuated Aβ toxicity in C elegans and stressed the significance of proteostasis in the prevention of age-related diseases from a practical point of view. © The Author 2015.

Framing narrative journalism as a new genre: A case study of the Netherlands

PubMed Central

van Krieken, Kobie; Sanders, José

2016-01-01

Although narrative journalism has a long history in the Netherlands, it is in recent years being promoted as a ‘new’ genre. This study examines the motives underlying this promotional tactic. To that end, we analyze how narrative journalism is framed in (1) public expressions of the initiatives aimed at professionalization of the genre and (2) interviews with journalists and lecturers in journalism programs. Results indicate that in public discourse on narrative journalism, the genre is framed as moving, essential, and as high quality journalism. These frames indicate that the current promotion of narrative journalism as ‘new’ can be seen as a strategy that journalists apply to withstand the pressures they are facing in the competition with new media. These frames are deepened in the interviews with lecturers and practitioners, who frame narrative journalism as a dangerous game, a paradigm shift, and as the Holy Grail. These frames indicate that narrative journalism is regarded as the highest achievable goal for journalists, but that its practice comes with dangers and risks: it tempts journalists to abandon the traditional principles of objectivity and factuality, which can ultimately cause journalism to lose its credibility and authority. We discuss these findings in terms of boundary work and reflect on implications for narrative journalism’s societal function. PMID:29278262

New criteria for Alzheimer disease and mild cognitive impairment: implications for the practicing clinician.

PubMed

Budson, Andrew E; Solomon, Paul R

2012-11-01

In most research studies and clinical trials, Alzheimer disease (AD) has been diagnosed using the criteria developed by the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association work group in 1984. Developments over the last 27 years have lead to the need for new diagnostic criteria. Four articles in the journal Alzheimer's & Dementia in 2011 describe new criteria for AD dementia and mild cognitive impairment (MCI) due to the AD pathophysiological process (MCI due to AD) and the underlying rationale for them. These new criteria emphasize that the AD pathophysiological process starts years and perhaps decades before clinical symptoms, and that biomarkers can be used to detect amyloid β deposition and the effects of neurodegeneration in the brain. These new criteria are immediately helpful to the practicing clinician, providing more accurate and specific guidelines for the diagnosis of AD dementia and MCI due to AD. As new diagnostic tools and new treatments for AD become available, diagnosis using these criteria will enable patients with this disorder to receive the best possible care.

[The long pilgrimage of Spanish biomedical journals toward excellence. Who helps? Quality, impact and research merit].

PubMed

Alfonso, Fernando

2010-03-01

Biomedical journals must adhere to strict standards of editorial quality. In a globalized academic scenario, biomedical journals must compete firstly to publish the most relevant original research and secondly to obtain the broadest possible visibility and the widest dissemination of their scientific contents. The cornerstone of the scientific process is still the peer-review system but additional quality criteria should be met. Recently access to medical information has been revolutionized by electronic editions. Bibliometric databases such as MEDLINE, the ISI Web of Science and Scopus offer comprehensive online information on medical literature. Classically, the prestige of biomedical journals has been measured by their impact factor but, recently, other indicators such as SCImago SJR or the Eigenfactor are emerging as alternative indices of a journal's quality. Assessing the scholarly impact of research and the merits of individual scientists remains a major challenge. Allocation of authorship credit also remains controversial. Furthermore, in our Kafkaesque world, we prefer to count rather than read the articles we judge. Quantitative publication metrics (research output) and citations analyses (scientific influence) are key determinants of the scientific success of individual investigators. However, academia is embracing new objective indicators (such as the "h" index) to evaluate scholarly merit. The present review discusses some editorial issues affecting biomedical journals, currently available bibliometric databases, bibliometric indices of journal quality and, finally, indicators of research performance and scientific success.

Authors face many choices when selecting a journal for publication. Prospective authors, especially trainees, may be unaware of “predatory” online journals or how to differentiate them from legitimate journals. In this study, we assessed awareness of open-access and predatory journals among prospective authors attending scientific writing workshops; our long-term goal was to inform educational goals for the workshops. We surveyed participants of writing workshops at veterinary and medical schools and an international conference over a 1-year period. The survey included 14 statements for respondents to indicate agreement level on a Likert-like scale and four questions on awareness of resources about predatory journals; respondents also defined “predatory journal.” A total of 145 participants completed the survey: 106 (73.1%) from veterinary schools and 86 (59.3%) graduate students or residents. Fewer faculty (vs trainees) agreed that open access was an important factor in deciding where to publish; faculty and postdoctoral researchers were more likely to expect to pay more to publish in an open-access journal. Most respondents (120/145, 82.7%) agreed/strongly agreed that the decision to accept a manuscript should not be influenced by publication charges, but 50% (56/112) indicated that they “didn’t know” how publishing costs were supported. Of the 142 respondents who answered, 33 (23.0%) indicated awareness of the term “predatory journal”; 34 (23.9%) were aware of the Directory of Open Access Journals; 24 (16.9%) were aware of the Science “sting” article about predatory journals; and 7 (4.8%) were aware of Beall’s list. Most (93/144, 64.5%) definitions of predatory journals described poor but not predatory journal practices, and some respondents misunderstood the term completely. Mentors should help novice authors to be aware of predatory journals and to distinguish between legitimate and illegitimate open-access journals, thus selecting the best journal for their work.

The field of Alzheimer's disease (AD) research has grown exponentially over the past few decades, especially since the isolation and identification of amyloid-β from postmortem examination of the brains of AD patients. Recently, the Journal of Alzheimer's Disease (JAD) put forth approximately 300 research reports which were deemed to be the most influential research reports in the field of AD since 2010. JAD readers were asked to vote on these most influential reports. In this 3-part review, we review the results of the 300 most influential AD research reports to provide JAD readers with a readily accessible, yet comprehensive review of the state of contemporary research. Notably, this multi-part review identifies the "hottest" fields of AD research providing guidance for both senior investigators as well as investigators new to the field on what is the most pressing fields within AD research. Part 1 of this review covers pathogenesis, both on a molecular and macro scale. Part 2 review genetics and epidemiology, and part 3 covers diagnosis and treatment. This part of the review, pathology, reviews amyloid-β, tau, prions, brain structure, and functional changes with AD and the neuroimmune response of AD.

Many studies reported that physiotherapy interventions are available to treat Alzheimer's disease (AD), but the efficacy remains uncertain. To evaluate the effectiveness of physiotherapy intervention on AD. The data sources were searched from literature databases, journals, and reference lists from 1 January 1990 to the end of 1 April 2014. Randomized and non-randomized controlled trials with physiotherapy intervention were included in our meta-analysis. Jadad score and Newcastle-Ottawa scale were used to assess the quality of included trials. Outcome measures were cognition function, physical function, activity of daily life (ADL) and neuropsychiatric inventory (NPI). 23 trials met the inclusion standard finally. Significant changes were seen in cognitive function: Mini-Mental State Examination score (weighted mean difference (WMD): 1.84, 95% confidence interval (CI): [0.76, to, 2.93], p < 0.0001), and verbal fluency (standard mean difference (SMD): 0.34, 95% CI: [0.01 to 0.66], p = 0.04). Other outcomes are also significant, they were timed up and go test (SMD: 0.56, 95% CI: [0.30 to 0.83], p < 0.0001), berg functional balance scale (SMD: 1.11, 95% CI: [0.37 to 1.84], p = 0.003), 6-min walk distance test (SMD: 141.45, 95% CI: [11.72 to 271.18], p = 0.03), ADL (SMD: 0.78, 95% CI: [0.33 to 1.23], p = 0.0007) and NPI (SMD: -0.69, 95% CI: [-1.31 to -0.07], p = 0.03). The available data indicate that physiotherapy intervention may have benefits in AD. However, current data are not definitive; more carefully designed and conducted observational studies are needed to definitively establish that whether physiotherapy intervention can effectively alleviate symptoms of AD.

Little attention has been given to the burden of chronic urticaria (CU) in Japan compared with other skin diseases, such as atopic dermatitis (AD) and psoriasis. The primary objective of the RELEASE study was to evaluate the real-life quality-of-life impairment in CU patients in Japan. Data were collected from 1443 urticaria, 1668 AD and 435 psoriatic patients; 552 urticaria patients who presented urticaria symptoms for over 6 weeks were defined as CU. The mean Dermatology Life Quality Index (DLQI) total score was 4.8, 6.1 and 4.8 in CU, AD and psoriatic patients, respectively. Disease control of urticaria evaluated by the Urticaria Control Test (UCT) and DLQI exhibited a strong correlation with a Spearman's rank correlation coefficient of -0.7158. CU and AD patients had relatively higher scores in all Work Productivity and Activity Impairment - General Health subscales except for absenteeism. At the time of the survey, approximately 64% of CU patients reported UCT scores of <12 and demonstrated higher work productivity loss and activity impairment versus patients with UCT scores of ≥12. Patients with lower UCT scores also displayed a higher percentage of dissatisfaction with their health state and the treatment they received. Approximately 85% of patients with CU had visited dermatology clinics, and less than 20% had visited hospital, indicating existence of a highly burdened population outside specialized centers. These results highlight the unmet medical needs of CU patients, suggesting the need to increase awareness of CU burden among both physicians and patients and to pursue improved real-life patient care. © 2018 Novartis K.K.

Sicherer, Scott H; Leung, Donald Y M

2005-07-01

This review highlights some of the research advances in allergic skin disease, anaphylaxis, and hypersensitivity reactions to foods, drugs, and insects that were reported primarily in the Journal in 2004. Clinical observations included that gastrointestinal symptoms during anaphylaxis are associated with an increased risk for hypotension; recurrence of peanut allergy can occur for about 8% of children who pass an oral food challenge and is associated with continued avoidance of the food after the challenge; seafood allergy is reported by 2.3% of the US population; and determination of the time to resolution of childhood egg and milk allergy might be predictable by means of serial determination of food-specific IgE levels. The comorbid effects of atopic dermatitis (AD) on asthma and the role of topical calcineurin inhibitors in the therapy of AD were also addressed. Basic and translational research observations indicate that improved diagnosis and therapy might become possible on the basis of reported identification or characterization of allergens such as: lipid transfer proteins and birch pollen-related cross-reactive allergens in plant foods; proteins in scorpion venom that cross-react with proteins from imported fire ant; mosquito saliva proteins responsible for systemic anaphylaxis; and IgE binding to quinolones detectable with an in vitro immunoassay. In addition, advances in understanding immune regulation associated with abrogation of oral tolerance in food allergy and of dendritic cell function, modulation of regulatory T cells, and chemokine expression in AD have elucidated possible targets for future intervention.

Publicly Releasing a Large Simulation Dataset with NDS Labs

NASA Astrophysics Data System (ADS)

Goldbaum, Nathan

2016-03-01

Optimally, all publicly funded research should be accompanied by the tools, code, and data necessary to fully reproduce the analysis performed in journal articles describing the research. This ideal can be difficult to attain, particularly when dealing with large (>10 TB) simulation datasets. In this lightning talk, we describe the process of publicly releasing a large simulation dataset to accompany the submission of a journal article. The simulation was performed using Enzo, an open source, community-developed N-body/hydrodynamics code and was analyzed using a wide range of community- developed tools in the scientific Python ecosystem. Although the simulation was performed and analyzed using an ecosystem of sustainably developed tools, we enable sustainable science using our data by making it publicly available. Combining the data release with the NDS Labs infrastructure allows a substantial amount of added value, including web-based access to analysis and visualization using the yt analysis package through an IPython notebook interface. In addition, we are able to accompany the paper submission to the arXiv preprint server with links to the raw simulation data as well as interactive real-time data visualizations that readers can explore on their own or share with colleagues during journal club discussions. It is our hope that the value added by these services will substantially increase the impact and readership of the paper.

Video ads promoting condom use are a key component of media campaigns to stem the HIV epidemic. Recent neuroimaging studies in the context of smoking cessation, point to personal relevance as one of the key variables that determine the effectiveness of public health messages. While minority men who have sex with men (MSM) are at the highest risk of HIV infection, most safe-sex ads feature predominantly Caucasian actors in heterosexual scenarios. We compared brain respons of 45 African American MSM to safe sex ads that were matched (i.e. 'Targeted') to participants' sexual orientation and race, and 'Untargeted' ads that were un matched for these characteristics. Ad recall, perceived 'convincingness' and attitudes towards condom use were also assessed. We found that Targeted ads were better remembered than the Untargeted ads but perceived as equally convincing. Targeted ads engaged brain regions involved in self-referential processing and memory, including the amygdala, hippocampus, temporal and medial prefrontal cortices (MPFC) and the precuneus. Connectivity between MPFC and precuneus and middle temporal gyrus was stronger when viewing Targeted ads. Our results suggest that targeting may increase cognitive processing of safe sex ads and justify further prospective studies linking brain response to media public health interventions and clinical outcomes. © The Author (2016).

Kim, Annice E; Arnold, Kristin Y; Makarenko, Olga

2014-04-01

Electronic cigarettes (e-cigarettes) are growing in popularity, but little is known about the extent to which these products are advertised to consumers. To estimate expenditures for e-cigarette advertising in magazines, TV, the Internet, newspapers, and radio in the U.S. from 2011 to 2012. E-cigarette advertising data were obtained from leading media intelligence companies, Kantar Media and Nielsen. Estimated e-cigarette advertising expenditures were summarized across media channels for 2011 and 2012. Additional information on brands advertised and market-level buys (i.e., local versus national) also was examined. Overall, e-cigarette advertising expenditures across media channels tripled from $6.4 million in 2011 to $18.3 million in 2012. Expenditures were highest in magazines and TV and lowest in newspapers and on the Internet. More than 80 unique brands were advertised, but blu eCigs dominated ad spending, comprising 76.7% of all e-cigarette advertising expenditures in 2012. National markets were increasingly targeted from 54.9% of ad buys in 2011 to 87.0% of ad buys in 2012. E-cigarette advertising expenditures are increasing, with a greater focus on national markets and TV ads, which will likely increase consumer awareness and use of e-cigarettes in the future. Federal-level efforts are needed to mandate that e-cigarette companies report their advertising expenditures. Future studies should examine how e-cigarette advertising expenditures and message content influence consumer awareness of, interest in, and use of e-cigarettes. © 2013 American Journal of Preventive Medicine Published by American Journal of Preventive Medicine All rights reserved.

Eke, N; Nkanginieme, K E O

2002-01-01

The Nigerian health sector is beset with an underdeveloped Continuing Medical Education (CME) programme, a scarcity of reading materials and the lack of a reading culture. Recent issues of available journals were obtained and read to identify data such as: the ownership and base, presence of mission statement, print quality, administrative and editorial matters, abstract format, CME value of articles, advertisements, subscription information and communication channels and practice. The availability of the journals in the libraries of the three 'first generation' teaching hospitals and accessibility through the Medline were ascertained. Twenty-eight current journals were obtained. Lagos has the highest number of editorial bases. Fifteen journals belong to national medical associations, 2 to regions and 11 to institutions. The journal title was considered appropriate in 13, cover design was good in 15, paper quality was good in 20 and legibility was good in 11 journals. Poor editing was manifested by bad grammar, spelling and punctuation. Six journals contained review articles of good CME value. Eight journals had a full compliment of communication facilities. The existence of a functional independent administrative office or staff was indicated in 7 journals. No journal indicated the dates of submission and acceptance of articles. Twenty-one journals were on the shelf of the library of ABUTH, Zaria. Two journals are accessible through the Medline and another is on-line. Adequate funding and improved management will effectively address most of the problems identified.

A comparison of citations across multidisciplinary psychology journals: a case study of two independent journals.

PubMed

Schumm, Walter R

2010-02-01

Citation rates and impact factors are often used in an attempt to evaluate the apparent prestige of scholarly journals and the quality of research published by individual scholars. However, the apparent prestige of "top tier" journals may reflect aggressive marketing and advertising efforts as much as scholarship. Some journals have retained their independence from professional organizations and the funding, marketing, and advocacy policies that may be associated with such organizations. While lacking as much visibility as organizational journals and sometimes considered "lower tier," independent journals may be able to provide comparable scientific quality as measured by citation rates. To test this, the citation rates of 169 articles published by a frequently cited scholar were compared across first- and second-tier journals, including many sponsored and marketed by large professional organizations, and to rates for two independent journals combined, Psychological Reports and Perceptual and Motor Skills. Citation rates were higher for first-tier journals but for most comparisons, especially those that controlled for heterogeneity of variance, results did not differ in statistically significant ways among the three tiers of journals, though some nonsignificant trends (p < .15) were found. If citation rates of articles are any indication of scientific quality, tiered classifications of journals appear to be a relatively weak indicator of scientific merit; journals at any tier contain articles that are useful and of good quality.

2017-06-01

Spouses of Alzheimer's disease patients (AD spouses) may experience substantial health effects associated with their partner's chronic cognitive and behavioral dysfunction. Studies examining associations between the medical experiences of AD spouses in the period before and after their partner's AD diagnosis are limited, particularly those which measure health care resource use and cost. AD patients were identified through multiple Medicare claims containing an AD diagnostic code. Their spouses were identified through special coding in the Medicare eligibility records. The AD spouses were matched demographically to the spouses of Medicare beneficiaries without a history of AD. Longitudinal and annual cross-sectional Medicare cost comparisons utilized log-transformed linear regression. The longitudinal period of observation began 12 months before the AD patient's initial claim listing AD and continued for up to 38 months afterwards. The study identified 16,322 AD spouses. Total per person costs were 24% higher in AD spouses than in the controls ($694/month vs $561/month). AD spouses' excess costs began 3 months before their partners' AD diagnoses and continued for ≥30 months. Being an AD spouse predicted 29% higher Medicare costs after adjustment for chronic health status (P < .001). Increasing AD patient care complexity had a substantial impact on AD spouse Medicare costs (P < .001). This study documents a link between the health status of AD spouses and AD patients. Additional research is required to elicit the mechanism behind the association between AD spouse and AD patient diagnosis. © The Author 2017.

Jayaratne, Yasas Shri Nalaka; Zwahlen, Roger Arthur

2015-01-01

Bibliometrics are a set of methods, which can be used to analyze academic literature quantitatively and its changes over time. The objectives of this study were 1) to evaluate trends related to academic performance of dental journals from 2003 to 2012 using bibliometric indices, and 2) monitor the changes of the five dental journals with the highest and lowest impact factor (IF) published in 2003. Data for the subject category "Dentistry, Oral Surgery & Medicine" was retrieved from the Journal Citation Reports (JCR) published from 2003 to 2012. Linear regressions analysis was used to determine statistical trends over the years with each bibliometric indicator as the dependent variable and the JCR year as the predictor variable. Statistically significant rise in the total number of dental journals, the number of all articles with the steepest rise observed for research articles, the number of citations and the aggregate IF was observed from 2003 to 2012. The analysis of the five top and five bottom-tire dental journals revealed a rise in IF however, with a wide variation in relation to the magnitude of this rise. Although the IF of the top five journals remained relatively constant, the percentile ranks of the four lowest ranking journals in 2003 increased significantly with the sharpest rise being noted for the British Journal of Oral & Maxillofacial Surgery. This study revealed significant growth of dental literature in absolute terms, as well as upward trends for most of the citation-based bibliometric indices from 2003 to 2012. PMID:25781486

To identify nursing care most frequently missed in acute adult inpatient wards and to determine evidence for the association of missed care with nurse staffing. Research has established associations between nurse staffing levels and adverse patient outcomes including in-hospital mortality. However, the causal nature of this relationship is uncertain and omissions of nursing care (referred as missed care, care left undone or rationed care) have been proposed as a factor which may provide a more direct indicator of nurse staffing adequacy. Systematic review. We searched the Cochrane Library, CINAHL, Embase and Medline for quantitative studies of associations between staffing and missed care. We searched key journals, personal libraries and reference lists of articles. Two reviewers independently selected studies. Quality appraisal was based on the National Institute for Health and Care Excellence quality appraisal checklist for studies reporting correlations and associations. Data were abstracted on study design, missed care prevalence and measures of association. Synthesis was narrative. Eighteen studies gave subjective reports of missed care. Seventy-five per cent or more nurses reported omitting some care. Fourteen studies found low nurse staffing levels were significantly associated with higher reports of missed care. There was little evidence that adding support workers to the team reduced missed care. Low Registered Nurse staffing is associated with reports of missed nursing care in hospitals. Missed care is a promising indicator of nurse staffing adequacy. The extent to which the relationships observed represent actual failures, is yet to be investigated. © 2018 The Authors.

Biomedical journals lack a consistent method to detect outcome reporting bias: a cross-sectional analysis.

Huan, L N; Tejani, A M; Egan, G

2014-10-01

An increasing amount of recently published literature has implicated outcome reporting bias (ORB) as a major contributor to skewing data in both randomized controlled trials and systematic reviews; however, little is known about the current methods in place to detect ORB. This study aims to gain insight into the detection and management of ORB by biomedical journals. This was a cross-sectional analysis involving standardized questions via email or telephone with the top 30 biomedical journals (2012) ranked by impact factor. The Cochrane Database of Systematic Reviews was excluded leaving 29 journals in the sample. Of 29 journals, 24 (83%) responded to our initial inquiry of which 14 (58%) answered our questions and 10 (42%) declined participation. Five (36%) of the responding journals indicated they had a specific method to detect ORB, whereas 9 (64%) did not have a specific method in place. The prevalence of ORB in the review process seemed to differ with 4 (29%) journals indicating ORB was found commonly, whereas 7 (50%) indicated ORB was uncommon or never detected by their journal previously. The majority (n = 10/14, 72%) of journals were unwilling to report or make discrepancies found in manuscripts available to the public. Although the minority, there were some journals (n = 4/14, 29%) which described thorough methods to detect ORB. Many journals seemed to lack a method with which to detect ORB and its estimated prevalence was much lower than that reported in literature suggesting inadequate detection. There exists a potential for overestimation of treatment effects of interventions and unclear risks. Fortunately, there are journals within this sample which appear to utilize comprehensive methods for detection of ORB, but overall, the data suggest improvements at the biomedical journal level for detecting and minimizing the effect of this bias are needed. © 2014 John Wiley & Sons Ltd.

The study of droughts in the instrumental period can be based on various drought indices calculated usually from precipitation and temperature series. Documentary evidence, overlapping partly also with meteorological measurements, represents another important source utilisable particularly for the pre-instrumental period. Direct reports of drought or indirect indications of its impacts may be found in various individual or institutional sources: narrative written sources (annals, chronicles, commemorative records), weather diaries, personal and official correspondence, stall-keepers' and market songs, journalism, financial-economic records, religious sources (rogations, sermons, praying), special printed sources, chronograms, epigraphic sources ("hunger" stones). Corresponding data indicate directly meteorological drought and with describing of drought impacts also agricultural and hydrological droughts. The first credible direct drought information from the Czech Lands reports not any rain or snowfall during the 1090/1091 winter (Monk of Sázava). But data before AD 1500 are relatively scarce and they are related prevailingly to Bohemia. Density of precipitation/drought documentary records in the Czech Lands increases significantly after 1500. This allows create series of precipitation indices with classification of dry months in the scale -1 as dry, -2 as very dry and -3 as extremely dry month. Such dataset is important for the creation of 500-year Czech drought chronology.

Does pharmaceutical advertising affect journal publication about dietary supplements?

Advertising affects consumer and prescriber behaviors. The relationship between pharmaceutical advertising and journals' publication of articles regarding dietary supplements (DS) is unknown. We reviewed one year of the issues of 11 major medical journals for advertising and content about DS. Advertising was categorized as pharmaceutical versus other. Articles about DS were included if they discussed vitamins, minerals, herbs or similar products. Articles were classified as major (e.g., clinical trials, cohort studies, editorials and reviews) or other (e.g., case reports, letters, news, and others). Articles' conclusions regarding safety and effectiveness were coded as negative (unsafe or ineffective) or other (safe, effective, unstated, unclear or mixed). Journals' total pages per issue ranged from 56 to 217 while advertising pages ranged from 4 to 88; pharmaceutical advertisements (pharmads) accounted for 1.5% to 76% of ad pages. Journals with the most pharmads published significantly fewer major articles about DS per issue than journals with the fewest pharmads (P < 0.01). Journals with the most pharmads published no clinical trials or cohort studies about DS. The percentage of major articles concluding that DS were unsafe was 4% in journals with fewest and 67% among those with the most pharmads (P = 0.02). The percentage of articles concluding that DS were ineffective was 50% higher among journals with more than among those with fewer pharmads (P = 0.4). These data are consistent with the hypothesis that increased pharmaceutical advertising is associated with publishing fewer articles about DS and publishing more articles with conclusions that DS are unsafe. Additional research is needed to test alternative hypotheses for these findings in a larger sample of more diverse journals.

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.

How Far Has the International Neurourology Journal Progressed Since Its Transformation Into an English Language Journal?

PubMed Central

2014-01-01

Purpose The publisher of the International Neurourology Journal changed the text to English in 2010 to promote the journal as an international publication. Four years later, what has happened to this journal? This paper will use citation indicators to describe the degree of internationalization. Methods Citation indicators such as impact factors, total citations from Web of Science, Science Journal Rankings (SJR), cites per documents (2 years), and Hirsch indexes (h-indexes) from Web of Science, digital object identifier (DOI)/CrossRef, ScimagoJR, or Scopus were calculated. In addition, the native countries of the authors and researchers citing the journal in Web of Science were analyzed. Results Impact factors in 2012 and 2013 were 0.645 and 0.857, respectively. Total citations in 2011, 2012, and 2013 from Web of Science were 15, 51, and 99, respectively, and the SJRs in 2011 and 2012 were 0.220 and 0.390, respectively. The h-indexes from DOI/CrossRef, Scopus, and Web of Science were 7, 8, and 6, respectively. Out of 153 unsolicited published papers, 27 (17.6%) were from outside of Korea. The researchers citing the journal in Web of Science and Scopus were primarily from the United States, Korea, China, the United Kingdom, and France. Funding agencies supported 39 of 101 original articles (38.6%). Conclusions After changing the text to the English language, the citation indicators show that the International Neurourology Journal has been elevated to an international journal. Although the nationality of authors varies from year to year, the increase in the number of manuscripts from international authors is obvious. PMID:24729921

Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed.

The Cambridge Structural Database (CSD) now contains data for more than a quarter of a million small-molecule crystal structures. The information content of the CSD, together with methods for data acquisition, processing and validation, are summarized, with particular emphasis on the chemical information added by CSD editors. Nearly 80% of new structural data arrives electronically, mostly in CIF format, and the CCDC acts as the official crystal structure data depository for 51 major journals. The CCDC now maintains both a CIF archive (more than 73,000 CIFs dating from 1996), as well as the distributed binary CSD archive; the availability of data in both archives is discussed. A statistical survey of the CSD is also presented and projections concerning future accession rates indicate that the CSD will contain at least 500,000 crystal structures by the year 2010.

The 2- to 6-page print journal article has been the standard for 200 years, yet this format severely limits the amount of detailed information that can be conveyed. The World Wide Web provides a low-cost option for posting extended text and supplementary information. It also can enhance the experience of journal editors, reviewers, readers, and authors through added functionality (eg, online submission and peer review, postpublication critique, and e-mail notification of table of contents.) Our aim was to characterize ways that journals were using the World Wide Web in 2005 and note changes since 2003. We analyzed the Web sites of 138 high-impact print journals in 3 ways. First, we compared the print and Web versions of March 2003 and 2005 issues of 28 journals (20 of which were randomly selected from the 138) to determine how often articles were published Web only and how often print articles were augmented by Web-only supplements. Second, we examined what functions were offered by each journal Web site. Third, for journals that offered Web pages for reader commentary about each article, we analyzed the number of comments and characterized these comments. Fifty-six articles (7%) in 5 journals were Web only. Thirteen of the 28 journals had no supplementary online content. By 2005, several journals were including Web-only supplements in >20% of their papers. Supplementary methods, tables, and figures predominated. The use of supplementary material increased by 5% from 2% to 7% in the 20-journal random sample from 2003 to 2005. Web sites had similar functionality with an emphasis on linking each article to related material and e-mailing readers about activity related to each article. There was little evidence of journals using the Web to provide readers an interactive experience with the data or with each other. Seventeen of the 138 journals offered rapid-response pages. Only 18% of eligible articles had any comments after 5 months. Journal Web sites offer similar functionality. The use of online-only articles and online-only supplements is increasing.

To evaluate the editorial quality, diffusion, relevance of the scientific content, and the publication practices of the specialised journal Revista Española de Enfermedades Digestivas. We checked 136 parameters based on ISO standards, the recommendations of scientific and editorial organisations, and studies of scientific editing and international publishing practices for biomedical journals. Diffusion was calculated using national and international databases, specialised libraries in Spain, and Internet sources. The analysis of the scientific content and publication practices was based on bibliometric indicators for the journal, authorship, and contributions. The sample for this study comprised six alternate issues of volume number 88 (1996), the last issue of this volume, and the first issue of volume 89 (1997). The samples used for the bibliometric analysis varied depending on the characteristics of specific indicators and the availability of information. The overall mean value for compliance with standards was 46.1%, while the real mean was calculated at 72.21%. The editorial procedures at the journal are similar to those of analogous international journals. The Revista Española de Enfermedades Digestivas is included in international databases of biomedical journals, and in the interdisciplinary international database SCI. It was found to be present in 70% of the medical libraries of Spanish universities, and in 73% of the hospital libraries studied. Bibliometric indicators showed co-authorship to be 5.5%; the origin of the authors grouped by province and by type of institutional affiliations showed 27.8% of all authors to be from Madrid, and that more were affiliated with general hospitals than with university hospitals. The mean delay between initial receipt of a manuscript and its publication was 300 days. Cocitation analysis gave the journal a central position amongst the 38 Spanish biomedical journals considered representative of the field. The journal's impact factor for 1996 was 0.260. The Revista Española de Enfermedades Digestivas is a high-quality vehicle of research results, and has acceptable internal editorial procedures. The journal is widely distributed, though its visibility on the Internet should be improved. Co-authorship is similar to that seen in other medical journals. Steps should be taken to make this journal better known within Spain, and to reduce the delay between the initial receipt and the final publication of manuscripts. Its impact factor is increasing steadily.

Beyond rankings: using cognitive mapping to understand what health care journals represent.

Studies of journal ratings are often controversial. Indices, including impact factors, acceptance rates, expert opinions, and ratings of knowledge, relevance, and quality have been used to organize journals hierarchically. While there may be some validity in consensus rankings, it is unclear what purpose is actually achieved by these endeavors. Impact factors probably help researchers identify authoritative journals, but other rankings likely indicate little more than institutionalized perceptions of prestige. Ranking schema used to derive evaluative judgments do not provide information about the organization of journals from the perspective of substantive content, emphasis, or targeted audience. A cognitive mapping approach that examines how health care management faculty members represent their perceptions of North American health care-oriented journals is presented as an alternative. A card-sort task and importance rating scale was mailed to faculty of North American health management programs who participated in a previous journal ranking study conducted by the authors. Completed assessments were returned from 147 respondents for a response rate of 39%. Multidimensional scaling and hierarchical cluster analyses of data provided a three-dimensional, seven cluster map that illustrates the perceived similarities of journals. Dimension I contrasts Applied Management Practice with Health Policy journals. Dimension II contrasts specific domain with broad-based research journals. Dimension III contrasts finance-oriented with delivery-oriented journals. The seven clusters of perceptually similar journals were weighted in terms of respondent defined importance ascribed to each journal within a cluster. This framework supplements ratings by providing insight about how journals are cognitively organized by scholars.

Chemosensory (olfaction-taste) dysfunctions are considered as reliable biomarkers in many neurological and psychiatric states. However, experimental measures of chemosensory abilities are lacking in alcohol-dependence (AD) and Korsakoff Syndrome (KS, a neurological complication of AD), despite the role played by alcohol-related odors and taste in the emergence and maintenance of AD. This study thus investigated chemosensory impairments in AD and KS. Olfactory-gustatory measures were taken among 20 KS, 20 AD, and 20 control participants. Olfaction (odor detection-discrimination-identification) was assessed using the "Sniffin Sticks" battery and taste was measured using the "Taste Strips" task. Impairments were found for high-level olfaction in AD (odor discrimination) and KS (odor discrimination-identification), even after controlling for psychopathological comorbidities. Gustatory deficits were also observed in both groups, indexing a global deficit for chemosensory perception. Finally, the gradient of impairment between the successive disease stages for odor identification suggests that the hypothesis of a continuum between AD and KS regarding cognitive deficits can be generalized to chemosensory perception. AD and KS are thus characterized by deficits in chemosensory abilities, which could constitute a marker of the AD-KS transition. In view of its deleterious influence on everyday life, chemosensory dysfunction should also be taken into account in clinical settings. © The Author 2015. Published by Oxford University Press.

Accidents are one of the leading causes of death among U.S. active-duty Army soldiers. Evidence-based approaches to injury prevention could be strengthened by adding person-level characteristics (e.g., demographics) to risk models tested on diverse soldier samples studied over time. To identify person-level risk indicators of accident deaths in Regular Army soldiers during a time frame of intense military operations, and to discriminate risk of not-line-of-duty from line-of-duty accident deaths. Administrative data acquired from multiple Army/Department of Defense sources for active duty Army soldiers during 2004-2009 were analyzed in 2013. Logistic regression modeling was used to identify person-level sociodemographic, service-related, occupational, and mental health predictors of accident deaths. Delayed rank progression or demotion and being male, unmarried, in a combat arms specialty, and of low rank/service length increased odds of accident death for enlisted soldiers. Unique to officers was high risk associated with aviation specialties. Accident death risk decreased over time for currently deployed, enlisted soldiers and increased for those never deployed. Mental health diagnosis was associated with risk only for previous and never-deployed, enlisted soldiers. Models did not discriminate not-line-of-duty from line-of-duty accident deaths. Adding more refined person-level and situational risk indicators to current models could enhance understanding of accident death risk specific to soldier rank and deployment status. Stable predictors could help identify high risk of accident deaths in future cohorts of Regular Army soldiers. Copyright © 2014 American Journal of Preventive Medicine. All rights reserved.

Mild cognitive impairment (MCI) is a high-risk condition for progression to Alzheimer's disease (AD). Vascular health is a key mechanism underlying age-related cognitive decline and neurodegeneration. AD-related genetic risk factors may be associated with preclinical cognitive status changes. We examine independent and cross-domain interactive effects of vascular and genetic markers for predicting MCI status and stability. We used cross-sectional and 2-wave longitudinal data from the Victoria Longitudinal Study, including indicators of vascular health (e.g., reported vascular diseases, measured lung capacity and pulse rate) and genetic risk factors-that is, apolipoprotein E (APOE; rs429358 and rs7412; the presence vs absence of ε4) and catechol-O-methyltransferase (COMT; rs4680; met/met vs val/val). We examined associations with objectively classified (a) cognitive status at baseline (not impaired congnitive (NIC) controls vs MCI) and (b) stability or transition of cognitive status across a 4-year interval (stable NIC-NIC vs chronic MCI-MCI or transitional NIC-MCI). Using logistic regression, indicators of vascular health, both independently and interactively with APOE ε4, were associated with risk of MCI at baseline and/or associated with MCI conversion or MCI stability over the retest interval. Several vascular health markers of aging predict MCI risk. Interactively, APOE ε4 may intensify the vascular health risk for MCI. © The Author 2015.

To examine the relationships between study quality, author prestige, journal impact factors, and citation rates of trials and to examine whether journal impact factors mediated the relationships between study quality and author prestige on citation rates. We used bibliometric data from 128 controlled trials included in a recent meta-analysis on brief alcohol interventions for adolescents and young adults. We obtained the number of citations from ISI Web of Knowledge and Google Scholar; journal impact factors were obtained from ISI Web of Knowledge. Linear regression models were used to examine the direct and indirect effects of interest. The results indicated that studies were published in journals with higher impact factors when first authors had higher h-indices and studies were funded, but this was largely because those studies were of higher quality. Studies were cited more frequently when first authors had higher h-indices and studies were funded, even after adjusting for study quality proxies. The observed associations between study quality and author prestige on citation rates were also partly mediated through journal impact factors. We conclude that studies conducted by more established authors and reported in more prestigious journal outlets are more likely to be cited by other scholars, even after controlling for various proxies of study quality.

Awareness of the latest scientific research and publishing articles in top journals is one of the major concerns of health researchers. In this study, we first introduced top journals of obstetrics and gynecology field based on their Impact Factor (IF), Eigenfactor Score (ES) and SCImago Journal Rank (SJR) indicator indexed in Scopus databases and then the scientometric features of longitudinal changes of SJR in this field were presented. In our analytical and bibiliometric study, we included all the journals of obstetrics and gynecology field which were indexed by Scopus from 1999 to 2013. The scientometric features in Scopus were derived from SCImago Institute and IF and ES were obtained from Journal Citation Report through the Institute for Scientific Information. Generalized Estimating Equation was used to assess the scientometric features affecting SJR. From 256 journals reviewed, 54.2% and 41.8% were indexed in the Pubmed and the Web of Sciences, respectively. Human Reproduction Update based on the IF (5.924±2.542) and SJR (2.682±1.185), and American Journal of obstetrics and gynecology based on the ES (0.05685±0.00633) obtained the first rank among the other journals. Time, Index in Pubmed, H_index, Citable per Document, Cites per Document, and IF affected changes of SJR in the period of study. Our study showed a significant association between SJR and scientometric features in obstetrics and gynecology journals. According to this relationship, SJR may be an appropriate index for assessing journal quality.

Context-aware brain-computer interfaces: exploring the information space of user, technical system and environment

Zander, T. O.; Jatzev, S.

2012-02-01

Brain-computer interface (BCI) systems are usually applied in highly controlled environments such as research laboratories or clinical setups. However, many BCI-based applications are implemented in more complex environments. For example, patients might want to use a BCI system at home, and users without disabilities could benefit from BCI systems in special working environments. In these contexts, it might be more difficult to reliably infer information about brain activity, because many intervening factors add up and disturb the BCI feature space. One solution for this problem would be adding context awareness to the system. We propose to augment the available information space with additional channels carrying information about the user state, the environment and the technical system. In particular, passive BCI systems seem to be capable of adding highly relevant context information—otherwise covert aspects of user state. In this paper, we present a theoretical framework based on general human-machine system research for adding context awareness to a BCI system. Building on that, we present results from a study on a passive BCI, which allows access to the covert aspect of user state related to the perceived loss of control. This study is a proof of concept and demonstrates that context awareness could beneficially be implemented in and combined with a BCI system or a general human-machine system. The EEG data from this experiment are available for public download at www.phypa.org. Parts of this work have already been presented in non-journal publications.

2010-01-01

Objectives: 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). Methods: 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. Results: 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. Conclusions: 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. PMID:23093877

2016-06-01

The article presents an outline of the 25-year history of the journal "Reports on Geodesy and Geoinformatics". The source of information was mainly the journal issues themselves. Attention was drawn to changes that the journal underwent over a quarter of a century and its relationship with the Institute of Geodesy and Geodetic Astronomy and later the Department of Geodesy and Geodetic Astronomy. Many issues were dedicated to materials from Polish conferences - those organised by the Institute and the international ones attended by the employees of the Institute, which was indicated in the section on the history of the journal. The second part of the article concerns the current activity and importance of the journal. Attention was paid to visibility of "Reports on Geodesy and Geoinformatics" in the domestic and foreign databases. Polish databases where the journal is indexed have been identified and briefly described. A separate issue is the evaluation of the journal, which forms a measure of its popularity among consumers. For this purpose, various parameters and biometrics indicators are used. The article used the Web of Science, Google Scholar and the Ministerial List databases for the assessment of the journal.

We present results of a study which goal was to investigate in which journals scientists in geosciences (i.e., in the fields covered by the AGU) in developing countries publish most of their papers.We were interested in particular in looking at the percentage of publications in AGU journals. Using science indicators collected by the Institute for Scientific Information (ISI), we analysed publication practices for 1997-2002 in the following countries : India, China, Russia, Brazil, Argentina and Chile. We investigated the evolution of the number of publications through time, identified most used journals, determined times cited and impact factors of papers published in the top 15 most used journals. We also determined the percentage of articles published in AGU journals versus other journals. We found that for the 6 counties considered, this percentage varies from about 2 to 3 percent (Argentina, China) to about 8 percent (the other 4 countries). Investigation of authors addresses indicates that the majority of articles published in AGU journals are multi-countries publications, involving international collaboration mainly with scientists from North America and Europe. Implications on page-charge and access to AGU journals are also discussed.

Citation Analysis of the Korean Journal of Urology From Web of Science, Scopus, Korean Medical Citation Index, KoreaMed Synapse, and Google Scholar

2013-01-01

The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases. PMID:23614057

One variable with which to evaluate scientific journals is how often their articles are cited in the literature. Such data are amenable to longitudinal analysis and can be used as a measure of a journal's impact on research within a discipline. We evaluated multiple citation measures for a number of applied journals in behavioral psychology from 1981 to 2000. The results indicate a relatively consistent impact across these journals, with some evidence of growth.

Zarit, Steven H; Kim, Kyungmin; Femia, Elia E; Almeida, David M; Klein, Laura C

2014-08-01

We examine the effects of use of adult day service (ADS) by caregivers of individuals with dementia (IWD) on daily stressors, affect, and health symptoms. Participants were interviewed for 8 consecutive days. On some days, the IWD attended an ADS program and on the other days caregivers provide most or all of the care at home. Participants were 173 family caregivers of IWDs using an ADS program. Daily telephone interviews assessed care-related stressors, noncare stressors, positive events, affect, and health symptoms. Multilevel models with data nested within persons were used to examine effects of ADS use on daily stressor exposure, affect, and health symptoms. Caregivers had lower exposure to care-related stressors on ADS days, more positive experiences, and more noncare stressors. ADS use lowered anger and reduced the impact of noncare stressors on depressive symptoms. The findings demonstrate that stressors on caregivers are partly lowered, and affect is improved on ADS days, which may provide protection against the effects of chronic stress associated with caregiving. © The Author 2013.

Mitchell, Kathryn D; Newton, Roberta A

2006-06-01

To determine (1) if older adults using an assistive device (AD) score lower on the Performance-Oriented Mobility Assessment (POMA) balance subscale (B-subscale) than individuals not using an AD; and (2) if a cut-score of 12 would indicate the need to use an AD. Elderly persons (n = 82, mean age = 82.1 years) were surveyed about AD use, health status, activity level and fall history. A one-time assessment of balance was conducted using the B-subscale. The 'arising task' was repeated to evaluate performance on the sit-to-stand task without using hands. A significant difference in B-subscale scores was observed between the two groups (AD; no AD), (P < 0.001). AD use was associated with lower activity level and health status. A cut-score of 12 points indicated device use (P = 0.000). The repeated 'arising task' demonstrated that 76.8% performed the task without using hands for support. Older adults using an AD will score lower on the B-subscale and report lower activity level and health status. A score of less than 12 on the B-subscale is indicative of AD need. Older adults who use an AD and self-report a falls history will score lower on the B-subscale than individuals using an AD and no reported history of falls.

Peer Review Quality and Transparency of the Peer-Review Process in Open Access and Subscription Journals.

Wicherts, Jelte M

2016-01-01

Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals' websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors' ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal's impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals.

Social media plays an increasingly important role in dissemination of knowledge and raising awareness of selected topics among the general public and the academic community. To investigate the relationship between social media metrics and academic indices of neurosurgical programs and journals. A 2-step online search was performed to identify official social media accounts of neurosurgical departments that were accredited by the Accreditation Council for Graduate Medical Education and the Royal College of Physicians and Surgeons of Canada. Dedicated neurosurgery and spine journals' social media accounts also were identified through an online search on SCImago Journal and Country Rank portal. Nonparametric tests were performed with bootstrapping to compare groups and to look for correlations between social media and academic metrics. We identified 36 social media accounts officially affiliated with academic neurosurgical institutions. These accounts represented 22 of 119 neurosurgical programs in North America (18.4%). The presence of a social media account for neurosurgical departments was associated with statistically significant higher values of academic impact metrics (P < 0.05). Specific social media metrics for neurosurgical department accounts, however, did not correlate with any values of academic indices. For journals, there were 11 journals present on social media and had greater academic metrics compared with journals without social media presence (P < 0.05). Social media presence is associated with stronger academic bibliometrics profiles for both neurosurgical departments and journals. The impact of social media metrics on indices of scientific impact in neurosurgery is not known. Copyright © 2016 Elsevier Inc. All rights reserved.

Case studies identify savings of up to $40,000 for academic research laboratories with the use of video journals

NASA Astrophysics Data System (ADS)

Pritsker, Moshe

2015-04-01

Recent studies indicate that 70% to 90% of results published in science journals are not reproducible, which presents troubling uncertainty about the future of scientific research. In contrast to the text format of traditional journals, novel video-based journals allow for systematic, step-by-step visualized demonstrations of research experiments. Video articles produce a more efficient transfer of knowledge between laboratories and therefore offer a viable solution to the issue of reproducibility. To quantify the savings of time and money generated by this alternative mode of scientific communication, we conducted a number of case studies among academic laboratories who use the peer-reviewed video journal JoVE. One study determined that using video as a guide to learn a new dissection technique saved a bioengineering lab at the University of Washington 40,000. A second case study found that a laboratory at Cornell University studying muscular dystrophy eliminated 6 months of experimentation by learning a new complex stem cell injection technique from the video journal. Results from a third study indicated that a laboratory at the University of Helsinki shortened the time to learn a surgical technique from 1 year to 2 weeks. Together, these studies indicate that video publication significantly enhances the reproducibility and productivity of scientific research.

Vividness of visual imagery and social desirable responding: correlations of the vividness of visual imagery questionnaire with the balanced inventory of desirable responding and the Marlowe-Crowne scale.

Allbutt, John; Ling, Jonathan; Rowley, Martin; Shafiullah, Mohammed

2011-09-01

Correlational research investigating the relationship between scores on self-report imagery questionnaires and measures of social desirable responding has shown only a weak association. However, researchers have argued that this research may have underestimated the size of the relationship because it relied primarily on the Marlowe-Crowne scale (MC; Crowne & Marlowe, Journal of Consulting Psychology, 24, 349-354, 1960), which loads primarily on the least relevant form of social desirable responding for this particular context, the moralistic bias. Here we report the analysis of data correlating the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, Journal of Mental Imagery, 19, 153-166, 1973) with the Balanced Inventory of Desirable Responding (BIDR; Paulhus, 2002) and the MC scale under anonymous testing conditions. The VVIQ correlated significantly with the Self-Deceptive Enhancement (SDE) and Agency Management (AM) BIDR subscales and with the MC. The largest correlation was with SDE. The ability of SDE to predict VVIQ scores was not significantly enhanced by adding either AM or MC. Correlations between the VVIQ and BIDR egoistic scales were larger when the BIDR was continuously rather than dichotomously scored. This analysis indicates that the relationship between self-reported imagery and social desirable responding is likely to be stronger than previously thought.

Healthy weight and lifestyle advertisements: an assessment of their persuasive potential.

Dixon, Helen; Scully, Maree; Cotter, Trish; Maloney, Sarah; Wakefield, Melanie

2015-08-01

This study aimed to identify and analyse the content of previously produced and aired adult-targeted public health advertisements (ads) addressing weight, nutrition or physical activity internationally. Ads were identified via keyword searches of Google, YouTube and websites of relevant government agencies and health organizations, and were eligible for inclusion if they were: in English; produced between 2007 and 2012; targeted at adults; ≤60 s; not promoting a particular commercial brand of food, fitness or weight loss product. Of the 99 ads coded, 59% featured supportive/encouraging messages, 36% presented information about health consequences and 17% focussed on social norms/acceptability issues. Supportive/encouraging messages were more frequently used in physical activity ads, while there were a higher proportion of messages about health consequences in weight ads. Execution style differed across lifestyle topics, with simulation/animation more common in nutrition ads and graphic images and negative personal testimonials in weight ads. Ads addressing weight were more likely to evoke high negative emotion and include potentially stigmatizing content. Understanding how weight and lifestyle issues have been addressed in recent public health advertising will help guide future efforts to test the effectiveness of different message types in facilitating positive behaviour changes. © The Author 2015.

Adding Dimensions to the Analysis of the Quality of Health Information of Websites Returned by Google: Cluster Analysis Identifies Patterns of Websites According to their Classification and the Type of Intervention Described.

PubMed

Yaqub, Mubashar; Ghezzi, Pietro

2015-01-01

Most of the instruments used to assess the quality of health information on the Web (e.g., the JAMA criteria) only analyze one dimension of information quality (IQ), trustworthiness. In this study, we analyzed the type of intervention that websites describe, whether supported by evidence-based medicine (EBM) or not, to provide a further dimension of IQ, accuracy, and correlated this with the established criteria. We searched Google for "migraine cure" and analyzed the first 200 websites for: (1) JAMA criteria (authorship, attribution, disclosure, currency); (2) class of websites (commercial, health portals, professional, patient groups, no-profit); and (3) type of intervention described (approved drugs, alternative medicine, food, procedures, lifestyle, drugs still at the research stage). We used hierarchical cluster analysis to identify different patterns of websites according to their classification and the information provided. Subgroup analysis on the first 10 websites returned was performed. Google returned health portals (44%), followed by commercial websites (31%) and journalism websites (11%). The type of intervention mentioned most often was alternative medicine (55%), followed by procedures (49%), lifestyle (42%), food (41%), and approved drugs (35%). Cluster analysis indicated that health portals are more likely to describe more than one type of treatment while commercial websites most often describe only one. The average JAMA score of commercial websites was significantly lower than for health portals or journalism websites, and this was mainly due to lack of information on the authors of the text and indication of the date the information was written. Looking at the first 10 websites from Google, commercial websites are underrepresented and approved drugs overrepresented. Analyzing the type of therapies/prevention methods provides additional information to the trustworthiness measures, such as the JAMA score, and could be a convenient and objective indicator of websites whose information is based on EBM.

The Astrophysics Source Code Library (ASCL, ascl.net) is a free online registry of codes used in astronomy research. With nearly 1,200 codes, it is the largest indexed resource for astronomy codes in existence. Established in 1999, it offers software authors a path to citation of their research codes even without publication of a paper describing the software, and offers scientists a way to find codes used in refereed publications, thus improving the transparency of the research. It also provides a method to quantify the impact of source codes in a fashion similar to the science metrics of journal articles. Citations using ASCL IDs are accepted by major astronomy journals and if formatted properly are tracked by ADS and other indexing services. The number of citations to ASCL entries increased sharply from 110 citations in January 2014 to 456 citations in September 2015. The percentage of code entries in ASCL that were cited at least once rose from 7.5% in January 2014 to 17.4% in September 2015. The ASCL's mid-2014 infrastructure upgrade added an easy entry submission form, more flexible browsing, search capabilities, and an RSS feeder for updates. A Changes/Additions form added this past fall lets authors submit links for papers that use their codes for addition to the ASCL entry even if those papers don't formally cite the codes, thus increasing the transparency of that research and capturing the value of their software to the community.

Impact factor of medical education journals and recently developed indices: Can any of them support academic promotion criteria?

Journal Impact Factor (JIF) has been used in assessing scientific journals. Other indices, h- and g-indices and Article Influence Score (AIS), have been developed to overcome some limitations of JIF. The aims of this study were, first, to critically assess the use of JIF and other parameters related to medical education research, and second, to discuss the capacity of these indices in assessing research productivity as well as their utility in academic promotion. The JIF of 16 medical education journals from 2000 to 2011 was examined together with the research evidence about JIF in assessing research outcomes of medical educators. The findings were discussed in light of the nonnumerical criteria often used in academic promotion. In conclusion, JIF was not designed for assessing individual or group research performance, and it seems unsuitable for such purposes. Although the g- and h-indices have demonstrated promising outcomes, further developments are needed for their use as academic promotion criteria. For top academic positions, additional criteria could include leadership, evidence of international impact, and contributions to the advancement of knowledge with regard to medical education.

A Step Beyond Simple Keyword Searches: Services Enabled by a Full Content Digital Journal Archive

NASA Technical Reports Server (NTRS)

Boccippio, Dennis J.

2003-01-01

The problems of managing and searching large archives of scientific journal articles can potentially be addressed through data mining and statistical techniques matured primarily for quantitative scientific data analysis. A journal paper could be represented by a multivariate descriptor, e.g., the occurrence counts of a number key technical terms or phrases (keywords), perhaps derived from a controlled vocabulary ( e . g . , the American Meteorological Society's Glossary of Meteorology) or bootstrapped from the journal archive itself. With this technique, conventional statistical classification tools can be leveraged to address challenges faced by both scientists and professional societies in knowledge management. For example, cluster analyses can be used to find bundles of "most-related" papers, and address the issue of journal bifurcation (when is a new journal necessary, and what topics should it encompass). Similarly, neural networks can be trained to predict the optimal journal (within a society's collection) in which a newly submitted paper should be published. Comparable techniques could enable very powerful end-user tools for journal searches, all premised on the view of a paper as a data point in a multidimensional descriptor space, e.g.: "find papers most similar to the one I am reading", "build a personalized subscription service, based on the content of the papers I am interested in, rather than preselected keywords", "find suitable reviewers, based on the content of their own published works", etc. Such services may represent the next "quantum leap" beyond the rudimentary search interfaces currently provided to end-users, as well as a compelling value-added component needed to bridge the print-to-digital-medium gap, and help stabilize professional societies' revenue stream during the print-to-digital transition.

Publishing in the Refereed International Journal of Astronomy & Earth Sciences Education JAESE

NASA Astrophysics Data System (ADS)

Slater, Timothy F.

2015-08-01

Filling a needed scholarly publishing avenue for astronomy education researchers and earth science education researchers, the Journal of Astronomy & Earth Sciences Education- JAESE was first published in 2014. JAESE is a scholarly, peer-reviewed scientific journal publishing original discipline-based education research and evaluation, with an emphasis of significant scientific results derived from ethical observations and systematic experimentation in science education and evaluation. International in scope, JAESE aims to publish the highest quality and timely articles from discipline-based education research that advance understanding of astronomy and earth sciences education and are likely to have a significant impact on the discipline or on policy. Articles are solicited describing both (i) systematic science education research and (ii) evaluated teaching innovations across the broadly defined Earth & space sciences education, including the disciplines of astronomy, climate education, energy resource science, environmental science, geology, geography, agriculture, meteorology, planetary sciences, and oceanography education. The publishing model adopted for this new journal is open-access and articles appear online in GoogleScholar, ERIC, EBSCO, ProQuest, and NASA SAO/ADS and are searchable in catalogs of 440,000 libraries that index online journals of its type. Rather than paid for by library subscriptions or by society membership dues, the annual budget is covered by page-charges paid by individual authors, their institutions, grants or donors: This approach is common in scientific journals, but is relatively uncommon in education journals. Authors retain their own copyright. The journal is owned by the Clute Institute in the United States, which owns and operates 17 scholarly journals and currently edited by former American Astronomical Society Education Officer Tim Slater, who is an endowed professor at the University of Wyoming and a Senior Scientist at the CAPER Center for Astronomy & Physics Education Research. More information about the journal and its policies are available online at http://www.JAESE.org

Indicators of national focus of the research published by Public Health journals edited in Brazil.

Packer, Abel Laerte

2015-07-01

This report presents a set of bibliometric indicators and statistics which explain the high level of production of articles on research in public and collective health in Brazil which are published in the main nationally edited journals in the field. The predominance of publications in the Portuguese language by Brazilian authors results in a lower impact in terms of citations received as measured by the bibliometric indexes Scimago/Scopus and JCR/WoS. These bibliometric indexes are used to measure the production and performance of research and journals. Nevertheless, the performance of these same journals stands out in SciELO, and is competitive internationally in the broader context of Google Scholar Metrics. The challenge faced by journals in Brazil is developing and applying editorial policies for the valuation of research with a national focus, and its internationalization.

2017-05-01

Despite the increasingly global nature of health care, much of the research about journal rankings and directions for future research in health care management is from a United States based viewpoint. There is a lack of information about influential journals and trends for health care management research from a global perspective. This exploratory study gathered the opinions of health care management researchers from 17 countries regarding which journals are considered most influential, popular research topics and areas needing more attention from the research community. An online survey was sent to individuals in high-income Organisation for Economic Co-operation and Development countries who were identified through author relationships, academic institution websites, editorial boards of international journals, and academic and practitioner associations in the countries of interest. Results indicate that journal rankings vary substantially from prior published studies evaluating health care management journals and international ranking lists, and the list of influential journals includes a much more diverse array of publications. Respondents also indicated a diverse number of topics for current and future research, highlighting the global complexity of the field. The implications of this study are valuable to scholars evaluating outlets for disseminating research, and highlighting areas for collaborative research in health care management globally.

Publishing in black and white: the relevance of listing of scientific journals.

2017-11-01

Scientific publishing, including in the field of Rheumatology, is evolving rapidly. Predatory journals are one of the major threats to contemporary publishing, especially to eager and naïve authors. In this narrative review, we discuss mechanisms that authors can employ to white list genuine scientific journals and blacklist "predatory" ones. Inclusion of a journal in reputed indices such as Medline (but not just Pubmed), Web of Science, Scopus or Embase raises the likelihood that the journal is genuine, more so if it is included in the current Journal Citation Reports. Other commercially available whitelists also exist, so also whitelists published by regulatory authorities in some countries. A commercially available blacklist has emerged since the very useful Beall's blacklist became defunct. In the absence of access to a whitelist or blacklist, certain characteristics such as repeated email solicitations for articles with an extremely narrow deadline from unknown sources, lack of inclusion in reputed indices, journals not published or endorsed by national or international society and scarcity of currently published articles should render authors suspicious of the genuine nature of a journal. National societies should work together to generate subject-specific (including Rheumatology specific) whitelists that can be available free of cost to authors from all over the world.

Alzheimer's disease neuroimaging initiative (ADNI) is a landmark imaging and omics study in AD. ADNI research literature has increased substantially over the past decade, which poses challenges for effectively communicating information about the results and impact of ADNI-related studies. In this work, we employed advanced information visualization techniques to perform a comprehensive and systematic mapping of the ADNI scientific growth and impact over a period of 12 years. Citation information of ADNI-related publications from 01/01/2003 to 05/12/2015 were downloaded from the Scopus database. Five fields, including authors, years, affiliations, sources (journals), and keywords, were extracted and preprocessed. Statistical analyses were performed on basic publication data as well as journal and citations information. Science mapping workflows were conducted using the Science of Science (Sci2) Tool to generate geospatial, topical, and collaboration visualizations at the micro (individual) to macro (global) levels such as geospatial layouts of institutional collaboration networks, keyword co-occurrence networks, and author collaboration networks evolving over time. During the studied period, 996 ADNI manuscripts were published across 233 journals and conference proceedings. The number of publications grew linearly from 2008 to 2015, so did the number of involved institutions. ADNI publications received much more citations than typical papers from the same set of journals. Collaborations were visualized at multiple levels, including authors, institutions, and research areas. The evolution of key ADNI research topics was also plotted over the studied period. Both statistical and visualization results demonstrate the increasing attention of ADNI research, strong citation impact of ADNI publications, the expanding collaboration networks among researchers, institutions and ADNI core areas, and the dynamic evolution of ADNI research topics. The visualizations presented here can help improve daily decision making based on a deep understanding of existing patterns and trends using proven and replicable data analysis and visualization methods. They have great potential to provide new insights and actionable knowledge for helping translational research in AD.

For this study, the authors analyzed the contents of 16 psychology journals for the presence of empirical articles on African Americans, Latinos, Asians, and Native Americans during the period ranging from 1990 to 1999. In 6 APA journals, there was a low percentage (4.7%) of such articles. African Americans were the most studied ethnic group. Data collected for this study also indicated that minority research has been increasing more in non-APA journals than in APA journals. In both APA and non-APA journals, counseling-oriented journals had higher percentages of minority articles than did journals of other subdisciplines. Possible explanations, consequences, and suggestions for future research are discussed.

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

1988-08-29

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

Objective: This study is to investigate the immunostimulatory activities of dendritic cells (DCs) transfected with HBcAg and/or HBsAg recombinant adenovirus (rAd). Methods: DCs were transfected with rAd (DC/Ad-C+Ad-S, DC/Ad-C, and DC/Ad-S), or pulsed with HBcAg antigen (DC/HBcAg). Flow cytometry was used to detect the phenotype of DCs and the cytokine production of T lymphocytes. Mice were vaccinated with DCs transfected with rAd or pulsed with antigen, and DNA vaccine. Mixed lymphocyte reaction (MLR) was used to evaluate the T-cell stimulatory capacity, and HBcAg-specific cytotoxic T lymphocyte (CTL) activity was assessed. Results: Phenotypic analysis showed that DCs transfected with rAd or pulsed with HBcAg antigen exhibited mature phenotypes. MLR indicated no significant differences in stimulating T-cell proliferation between the DC/rAd and DC/HBcAg groups. When mixed with DCs, Th and Tc cells mainly secreted IFN-γ, indicating type I immune responses. In vaccinated mice, DCs transduced with rAd and pulsed with HBcAg induced significantly more IFN-γ secretion from Th cells, compared with DNA vaccine, indicating stronger Th1 response. Moreover, DCs transduced with rAd stimulated Tc cells to produce more IFN-γ, indicating stronger Tc1 response. In vaccinated mice, HBcAg-specific CTL activities were decreased in the following order: the DC/Ad-C+Ad-S, DC/Ad-C, DC/Ad-S, DC/HBcAg, and DNA vaccine groups. Conclusion: DCs transfected with rAd induce stronger Th1/Tc1 (type I) cell immune responses and specific CTL response than HBcAg-pulsed DCs or DNA vaccine. Our findings suggest that DCs transfected with rAd-C/rAd-S might provide an effective approach in the treatment of persistent hepatitis B virus infection. PMID:26064236

Validating growth and development of a seabird as an indicator of food availability: captive-reared Caspian Tern chicks fed ad libitum and restricted diets

Lyons, Donald E.; Roby, Daniel D.

For seabirds raising young under conditions of limited food availability, reducing chick provisioning and chick growth rates are the primary means available to avoid abandonment of a breeding effort. For most seabirds, however, baseline data characterizing chick growth and development under known feeding conditions are unavailable, so it is difficult to evaluate chick nutritional status as it relates to foraging conditions near breeding colonies. To address this need, we examined the growth and development of young Caspian Terns (Hydroprogne caspia), a cosmopolitan, generalist piscivore, reared in captivity and fed ad libitum and restricted (ca. one-third lower caloric intake) diets. Ad libitum-fed chicks grew at similar rates and achieved a similar size at fledging as previously documented for chicks in the wild and had energetic demands that closely matched allometric predictions. We identified three general characteristics of food-restricted Caspian Tern chicks compared to ad libitum chicks: (1) lower age-specific body mass, (2) lower age-specific skeletal and feather size, such as wing chord length, and (3) heightened levels of corticosterone in blood, both for baseline levels and in response to acute stress. Effects of diet restriction on feather growth (10-11% slower growth in diet-restricted chicks) were less pronounced than effects on structural growth (37-52% slower growth) and body mass (24% lower at fledging age), apparently due to preferential allocation of food resources to maintain plumage growth. Our results suggest that measurements of chick body mass and feather development (e.g., wing chord or primary length) or measurement of corticosterone levels in the blood would allow useful evaluation of the nutritional status of chicks reared in the wild and of food availability in the foraging range of adults. Such evaluations could also inform demography studies (e.g., predict future recruitment) and assist in evaluating designated piscivorous waterbird conservation (colony) sites. ?? 2011 The Authors.

Tacrolimus (FK-506) has been found to exhibit potent inhibitory effects on spontaneously developed dermatitis. We previously showed that glucosamine prevents the development of Atopic dermatitis (AD)-like skin lesions in NC/Nga mice. The aims of our study were to investigate the synergistic therapeutic efficacy of combination of glucosamine plus FK-506 in dermatophagoides farina (Df)-induced AD-like skin lesions in NC/Nga mice and to determine the underlying therapeutic mechanisms. The Df-induced NC/Nga mice with a clinical score of 8 were used for treatment with glucosamine (500 mg/kg) alone, FK-506 (1.0 mg/kg) or in combination. The synergistic effects of combination therapy were evaluated by dermatitis scores, skin histology and immunological parameters such as IgE, Th2-mediated cytokines and chemokines, CD3(+) T cells and CLA(+) T cells. Combined therapy using glucosamine plus FK-506 improved the development of AD-like skin lesions as exemplified by a significant decrease in total skin symptom severity scores. The suppression of dermatitis by combined therapy was accompanied by a decrease in the plasma level of IgE and in the splenic level of IL-5, IL-13, TARC and eotaxin. Histological finding indicated that the dermal infiltration of inflammatory cells including mast cells and eosinophils was greatly reduced. Particularly, immunohistological evaluation reveals a reduction in CD3(+) T cells and CLA(+) cells in the combined therapy. Our findings suggest that combination therapy of glucosamine plus FK-506 was more synergistic efficacy than single-modality treatment with either alone to improve the development of established dermatitis in NC/Nga mice model. This combined immunosuppressive therapy may provide an effective therapeutic strategy for the treatment of AD. © 2011 The Authors. Scandinavian Journal of Immunology © 2011 Blackwell Publishing Ltd.

Food for thought: comparison of citations received from articles appearing in specialized eating disorder journals versus general psychiatry journals.

To conduct a bibliometric analysis of eating disorder journals to guide journal readers and researchers when submitting their manuscripts. Several indices were used to compare journal impact and citations of articles appearing between 1996 and 2010 in six eating disorders journals and six leading general psychiatry journals. The International Journal of Eating Disorders (IJED) had the highest journal impact factor (JIF, 2.278) of the six eating disorders' journals. The general psychiatry journals had higher JIFs and received more citations per eating disorder article than the specialized journals. However, IJED published the highest number of eating disorder articles between 1996 and 2010, and 35 of these articles received at least 100 citations. Using the JIF alone to decide where to submit a manuscript is a poor strategy, as this does not take into consideration the impact an article can have within the eating disorder's field over time.

Stability of a rigid rotor supported on oil-film journal bearings under dynamic load

Majumdar, B. C.; Brewe, D. E.

1987-01-01

Most published work relating to dynamically loaded journal bearings are directed to determining the minimum film thickness from the predicted journal trajectories. These do not give any information about the subsynchronous whirl stability of journal bearing systems since they do not consider the equations of motion. It is, however, necessary to know whether the bearing system operation is stable or not under such an operating condition. The stability characteristics of the system are analyzed. A linearized perturbation theory about the equilibrium point can predict the threshold of stability; however it does not indicate postwhirl orbit detail. The linearized method may indicate that a bearing is unstable for a given operating condition whereas the nonlinear analysis may indicate that it forms a stable limit cycle. For this reason, a nonlinear transient analysis of a rigid rotor supported on oil journal bearings under: (1) a unidirectional constant load, (2) a unidirectional periodic load, and (3) variable rotating load are performed. The hydrodynamic forces are calculated after solving the time-dependent Reynolds equation by a finite difference method with a successive overrelaxation scheme. Using these forces, equations of motion are solved by the fourth-order Runge-Kutta method to predict the transient behavior of the rotor. With the aid of a high-speed digital computer and graphics, the journal trajectories are obtained for several different operating conditions.

In this paper we analyze a collection of bibliographic networks, constructed from the data from the Web of Science on works (papers, books, etc.) on the topic of topological indices and on relating scientific fields. We present the general outlook and more specific findings about authors, works and journals, subtopics and keywords and also important relations between them based on scientometric approaches like the strongest and main citation paths, the main themes on citation path based on keywords, results of co-authorship analysis in form of the most prominent islands of citing authors, groups of collaborating authors, two-mode cores of authors and works. We investigate the nature of citing of authors, important journals and citing of works between them, journals preferred by authors and expose hierarchy of similar collaborating authors, based on keywords they use. We perform temporal analysis on one important journal as well. We give a comprehensive scientometric insight into the field of topological indices. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Low-income, low-literacy, limited English-proficient populations have low colorectal cancer (CRC) screening rates and experience poor patient-provider communication and decision-making processes around screening. The purpose of this study was to test the effect of a CRC screening decision aid on screening-related communication and decision making in primary care visits. RCT with data collected from patients at baseline and immediately after the provider encounter. Patients aged 50-75 years, due for CRC screening, were recruited from two safety net clinics in North Carolina and New Mexico (data collection, January 2014-September 2015; analysis, 2015). Participants viewed a CRC screening decision aid or a food safety (control) video immediately before their provider encounter. CRC screening-related knowledge, discussion, intent, test preferences, and test ordering. The study population (N=262) had a mean age of 58.3 years and was 66% female, 61% Latino, 17% non-Latino black, and 16% non-Latino white. Among Latino participants, 71% preferred Spanish. Compared with controls, intervention participants had greater screening-related knowledge (on average 4.6 vs 2.8 of six knowledge items correct, adjusted difference [AD]=1.8, 95% CI=1.5, 2.1) and were more likely to report screening discussion (71.0% vs 45.0%, AD=26.1%, 95% CI=14.3%, 38.0%) and high screening intent (93.1% vs 84.7%, AD=9.0%, 95% CI=2.0%, 16.0%). Intervention participants were more likely to indicate a specific screening test preference (93.1% vs 68.0%, AD=26.5%, 95% CI=17.2%, 35.8%) and to report having a test ordered (56.5% vs 32.1%, AD=25.8%, 95% CI=14.4%, 37.2%). Viewing a CRC screening decision aid before a primary care encounter improves knowledge and shared decision making around screening in a racially, ethnically, and linguistically diverse safety net clinic population.

To investigate the implications of obtaining one or more low scores on a battery of cognitive tests on diagnosing mild cognitive impairment (MCI). Observational longitudinal study. Alzheimer's Disease Neuroimaging Initiative. Normal controls (NC, n = 280) and participants with MCI (n = 415) according to Petersen criteria were reclassified using the Jak/Bondi criteria and number of impaired tests (NIT) criteria. Diagnostic statistics and hazard ratios of progression to Alzheimer's disease (AD) were compared according to diagnostic criteria. The NIT criteria were a better predictor of progression to AD than the Petersen or Jak/Bondi criteria, with optimal sensitivity, specificity, and positive and negative predictive value. Considering normal variability in cognitive test performance when diagnosing MCI may help identify individuals at greatest risk of progression to AD with greater certainty. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

Ethical issues in studying submissions to a medical journal.

Olson, C M; Glass, R M; Thacker, S B; Stroup, D F

1998-07-15

A protocol to prospectively study characteristics of meta-analyses submitted to a weekly medical journal raised several ethical issues. In submitting a manuscript for publication, authors do not implicitly consent to have their work used for research. Authors must be free to refuse to consent, without it affecting their chances for publication. Systematically analyzing data on manuscript characteristics might influence the decision to publish. Having investigators who are not on the editorial staff or peer reviewers extract the manuscripts' characteristics breaks the confidentiality of the author-editor-reviewer relationship. In response to these issues, we added a statement to our journal's instructions for authors that submitted manuscripts may be systematically analyzed to improve the quality of the editorial or peer review process. Authors had to actively consent to participate, but editors and external reviewers were unaware of which authors were participating. The manuscript characteristics were not shared with authors, editors, or external reviewers. The investigators were blinded to each manuscript's author and institution. After we addressed ethical issues encountered in studying manuscripts submitted to a medical journal, 99 of 105 authors submitting a meta-analysis during the study's first 24 months agreed to participate.

Understanding health beliefs and how they influence willingness will enable the development of targeted curricula that maximize public engagement in Alzheimer's disease (AD) risk reduction behaviors. Literature on behavioral theory and community input was used to develop and validate a health beliefs survey about AD risk reduction among 428 community-dwelling adults. Principal component analysis was performed to assess internal consistency. Linear regression was performed to identify key predictors of Willingness to engage in AD risk reduction behaviors. The measure as well as the individual scales (Benefits, Barriers, Severity, Susceptibility and Social Norm) were found to be internally consistent. Overall, as Benefits and Barriers scores increased, Willingness scores also increased. Those without prior AD experience or family history had lower willingness scores. Finally, we observed an interaction between age and norms, suggesting that social factors related to AD prevention may differentially affect people of different ages. The Alzheimer Prevention Beliefs Measure provides assessment of several health belief factors related to AD prevention. Age, Family History, Logistical Barriers and total Benefits are significant determinants of willingness to engage in AD risk reduction behaviors, such as seeing a doctor or making a lifestyle change. © The Author 2017.

The top-ten in journal impact factor manipulation.

PubMed

Falagas, Matthew E; Alexiou, Vangelis G

2008-01-01

A considerable part of the scientific community is, at least to some degree, involved in the "impact factor game". Editors strive to increase their journals' impact factor (IF) in order to gain influence in the fields of basic and applied research and scientists seek to profit from the "added value" of publishing in top IF journals. In this article we point out the most common "tricks" of engineering and manipulating the IF undertaken by a portion of professionals of the scientific publishing industry. They attempt to increase the nominator or decrease the denominator of the IF equation by taking advantage of certain design flaws and disadvantages of the IF that permit a degree of artificial and arbitrary inflation. Some of these practices, if not scientifically unethical, are at least questionable and should be abandoned. Editors and publishers should strive for quality through fair and thoughtful selection of papers forwarded for peer review and editorial comments that enhance the quality and scientific accuracy of a manuscript.

Visual processing in Alzheimer's disease: surface detail and colour fail to aid object identification.

PubMed

Adlington, Rebecca L; Laws, Keith R; Gale, Tim M

2009-10-01

It has been suggested that object recognition in patients with Alzheimer's disease (AD) may be strongly influenced both by image format (e.g. colour vs. line-drawn) and by low-level visual impairments. To examine these notions, we tested basic visual functioning and picture naming in 41 AD patients and 40 healthy elderly controls. Picture naming was examined using 105 images representing a wide range of living and nonliving subcategories (from the Hatfield image test [HIT]: [Adlington, R. A., Laws, K. R., & Gale, T. M. (in press). The Hatfield image test (HIT): A new picture test and norms for experimental and clinical use. Journal of Clinical and Experimental Neuropsychology]), with each item presented in colour, greyscale, or line-drawn formats. Whilst naming for elderly controls improved linearly with the addition of surface detail and colour, AD patients showed no benefit from the addition of either surface information or colour. Additionally, controls showed a significant category by format interaction; however, the same profile did not emerge for AD patients. Finally, AD patients showed widespread and significant impairment on tasks of visual functioning, and low-level visual impairment was predictive of patient naming.

Past Activity of Non-sorted Circles Fields in Northern Sweden

NASA Astrophysics Data System (ADS)

Becher, M.; Klaminder, J.

2011-12-01

Non-sorted circles (NSCs), also known as frost boils, are common geomorphological features created by cryogenic processes in subarctic and arctic soils [Washburn, 1979]. Near-surface permafrost is thought to be a prerequisite for the activity of NSCs [Walker et al., 2008], where an active NSC maintains a sparsely vegetated circle-like zone in the centre due to frost heave and up-freezing of silt. Little is known about the historical activity of NSCs in northern Scandinavia. Here we summarize some results of our ongoing research where we have assessed historical changes in NSC activity in the Abisko area, northern Sweden. In short, we have estimated how the distribution of NSCs along an altitude gradient has changed from 1959 to 2008 by using digitized aerial photos. Unsupervised classification with two classes (bare mineral soil and shrub vegetation) was performed on NSC fields to achieve estimations on how the aerial coverage of up-frozen mineral soil has changed over the last decades. Here, over growth of previous bare mineral soil surfaces by shrubs was interpreted as decreased NSC activity, considering that vascular plants are unable to colonize active NSCs due to significant heave and disruption of plant roots [Jonasson, 1986]. In addition to observations from aerial photos, we have conducted vertical sampling of NSC soil stratigraphies and 14C-dated buried organic soil layers to constrain the historical activity of the NSC in time. Preliminary analyses of the aerial photos indicate a general overgrowth of bare mineral surfaces within the NSCs since 1959. Of 137 studied sites 92 sites (corresponding to 67%) show an net overgrowth of previous bare mineral soil surface within the circles. On average, about 29 % of the bare mineral soil within the NSC fields is estimated to have been colonized by shrub vegetation. Clearly, our findings indicate that permafrost-controlled soil frost activities of the studied NSCs have mainly decreased during the last five decades. The preliminary result of 14C dating (at the time of writing 5) of buried organic layers indicates an onset of NSC activity ~AD 1200. Observations of up-frozen silt deposited on top of podsolized soil in the excavated pits witness that stable soil conditions prevailed prior to the onset of NSC activity. Furthermore, several buried organic layers date back to approximately 1900 AD, indicating a high activity in NSCs at least until this time. Considering that NSC activity is thought to be indicative of permafrost, our results suggest that uphill soils in the study area were affected to a limited extent by cryoturbic processes until the end of the Medieval Warm Period ~AD 1200. Permafrost has likely been present in the soils above tree-line at least until around AD 1900. After AD 1900 the permafrost has likely disappeared from most of the NSC sites, lowering the activity of the NSCs. A finding supported by the plant overgrowth of the NSC fields since 1959 seen in the aerial photos. References Jonasson, S. (1986), Geografiska Annaler, 68, 185-195. Walker, D. A., et al.

The results of studies of bone mineral density in Addison's disease (AD) are inconsistent. There are no published data on hip fracture risk in patients with AD. In this study, we compare hip fracture risk in adults with and without AD. A population-based cohort study. Through the Swedish National Patient Register and the Total Population Register, we identified 3219 patients without prior hip fracture who were diagnosed with AD at the age of ≥30 years during the period 1964-2006 and 31 557 age- and sex-matched controls. Time to hip fracture was measured. We observed 221 hip fractures (6.9%) in patients with AD and 846 (2.7%) in the controls. Patients with AD had a higher risk of hip fracture [hazard ratio (HR) = 1.8; 95% confidence interval (CI), 1.6-2.1; P < 0.001]. This risk increase was independent of sex and age at or calendar period of diagnosis. Risk estimates did not change with adjustment for type 1 diabetes, autoimmune thyroid disease, rheumatoid arthritis or coeliac disease. Women diagnosed with AD ≤50 years old had the highest risk of hip fracture (HR = 2.7; 95 % CI, 1.6-4.5). We found a positive association between hip fracture and undiagnosed AD [odds ratio (OR) = 2.4; 95 % CI, 2.1-3.0] with the highest risk estimates in the last year before AD diagnosis (OR = 2.8; 95 % CI, 1.8-4.2). Both clinically undiagnosed and diagnosed AD was associated with hip fractures, with the highest relative risk seen in women diagnosed with AD ≤50 years of age. © 2011 The Association for the Publication of the Journal of Internal Medicine.

Differential functional connectivity of rostral anterior cingulate cortex during emotional interference.

The rostral-ventral subdivision of the anterior cingulate cortex (rACC) plays a key role in the regulation of emotional processing. Although rACC has strong anatomical connections with anterior insular cortex (AIC), amygdala, prefrontal cortex and striatal brain regions, it is unclear whether the functional connectivity of rACC with these regions changes when regulating emotional processing. Furthermore, it is not known whether this connectivity changes with deficits in emotion regulation seen in different kinds of anxiety and depression. To address these questions regarding rACC functional connectivity, non-patients high in self-reported anxious apprehension (AP), anxious arousal (AR), anhedonic depression (AD) or none (CON) indicated the ink color of pleasant, neutral and unpleasant words during functional magnetic resonance imaging. While ignoring task-irrelevant unpleasant words, AD and CON showed an increase in the functional connectivity of rACC with AIC, putamen, caudate and ventral pallidum. There was a decrease in this connectivity in AP and AR, with AP showing greater reduction than AR. These findings provide support for the role of rACC in integrating interoceptive, emotional and cognitive functions via interactions with insula and striatal regions during effective emotion regulation in healthy individuals and a failure of this integration that may be specific to anxiety, particularly AP. © The Author (2016).

To assess the usefulness of the Montreal Cognitive Assessment (MoCA) total score (MoCA-TS) and Memory Index Score (MoCA-MIS) in predicting conversion to Alzheimer's disease (AD) in individuals with mild cognitive impairment (MCI). Retrospective chart review. Community-based memory clinic. Individuals meeting Petersen's MCI criteria (N = 165). Baseline MoCA scores at MCI diagnosis were collected from charts of eligible individuals with MCI, and MoCA-TS, MoCA-MIS, and a cognitive domain index score were calculated to assess their prognostic value in predicting conversion to AD. One hundred fourteen participants progressed to AD (MCI-AD), and 51 did not (nonconverters; MCI-NC); 90.5% of participants with MCI with a MoCA-TS less than 20/30 and a MoCA-MIS less than 7/15 at baseline converted to AD within the average follow-up period of 18 months, compared with 52.7% of participants with MCI above the cutoffs on both scores. Individuals with multiple-domain amnestic MCI had the highest AD conversion rates (73.9%). Identifying individuals with MCI at high risk of conversion to AD is important clinically and for selecting appropriate subjects for therapeutic trials. Individuals with MCI with a low MoCA-TS and a low newly devised memory index score (MoCA-MIS) are at greater risk of short-term conversion to AD. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

SOX5 encodes a transcription factor that is expressed in multiple tissues including heart, lung and brain. Mutations in SOX5 have been previously found in patients with amyotrophic lateral sclerosis (ALS) and developmental delay, intellectual disability and dysmorphic features. To characterize the neuronal role of SOX5, we silenced the Drosophila ortholog of SOX5, Sox102F, by RNAi in various neuronal subtypes in Drosophila. Silencing of Sox102F led to misorientated and disorganized michrochaetes, neurons with shorter dendritic arborization (DA) and reduced complexity, diminished larval peristaltic contractions, loss of neuromuscular junction bouton structures, impaired olfactory perception, and severe neurodegeneration in brain. Silencing of SOX5 in human SH-SY5Y neuroblastoma cells resulted in a significant repression of WNT signaling activity and altered expression of WNT-related genes. Genetic association and meta-analyses of the results in several large family-based and case-control late-onset familial Alzheimer's disease (LOAD) samples of SOX5 variants revealed several variants that show significant association with AD disease status. In addition, analysis for rare and highly penetrate functional variants revealed four novel variants/mutations in SOX5, which taken together with functional prediction analysis, suggests a strong role of SOX5 causing AD in the carrier families. Collectively, these findings indicate that SOX5 is a novel candidate gene for LOAD with an important role in neuronal function. The genetic findings warrant further studies to identify and characterize SOX5 variants that confer risk for AD, ALS and intellectual disability. © The Author 2017.

2007-10-01

To determine the levels of functional near visual acuity required for everyday social reading activities and to compare the levels to those attained with accommodative and monofocal intraocular lenses (LOLs). Font size equivalencies of an Early Treatment Diabetic Retinopathy Study near chart and a variety of commonly read print objects were determined and correlated to the findings of distance-corrected near vision measurements with 2 accommodative (Tetraflex, 1CU) and 1 monofocal (Acrysof MA30) IOLs. The smallest print objects studied were sweetener packets with type between 20/40 (Jaeger [J] 5) and 20/50 (J6). Type in classified ads, stock quotations, and pocket bibles was 20/50 (J6), type in a telephone directory was 20/63 (J8), and type in standard newspapers, journals, and magazines was 20/80 (J9). Tested monocularly, 88% of Tetraflex, 40% of ICU, and 7% of Acrysof MA30 eyes had distance-corrected near vision sufficient to read newspaper and telephone directory print, and 63% of Tetraflex, 30% of 1CU, and 0% of Acrysof MA30 eyes could read classified ads, stock quotations, and pocket bibles, respectively. Tested binocularly after bilateral implantation, 96% of Tetraflex patients could read telephone directory print and 89% could read ads, stock quotations, and pocket bibles. Functional near visual acuity is not equivalent to the bottom-line objective at 20/20 (J1) near visual acuity. No print size was found at or smaller than 20/40 (J5), indicating that a requirement of nearly perfect near visual acuity, while desirable, may not be necessary for patients' social reading needs for accommodative IOLs.

Message sidedness in advertising: the moderating roles of need for cognition and time pressure in persuasion.

PubMed

Kao, Danny Tengti

2011-08-01

Persuasion has been extensively researched for decades. Much of this research has focused on different message tactics and their effects on persuasion (e.g., Chang & Chou, 2008; Lafferty, 1999). This research aims to assess whether the persuasion of a specific type of message is influenced by need for cognition (NFC) and time pressure. The 336 undergraduates participated in a 2 (message sidedness: one-sided/two-sided) × 3 (time pressure: low/moderate/high) between-subjects design. Results indicate that two-sided messages tend to elicit more favorable ad attitudes than one-sided messages. As compared with low-NFC individuals, high-NFC individuals are likely to express more favorable ad attitudes, brand attitudes and purchase intention. Moderate time pressure tends to lead to more favorable ad attitudes than low time pressure and high time pressure. In addition, moderate time pressure is likely to elicit more favorable brand attitudes and purchase intentions than high time pressure, but does not elicit more favorable brand attitudes and purchase intentions than low time pressure. Furthermore, when high-NFC individuals are under low or moderate time pressure, two-sided messages are more persuasive than one-sided messages; however, message sidedness does not differentially affect the persuasion when high-NFC individuals are pressed for time. In contrast, one-sided messages are more persuasive than two-sided messages when low-NFC individuals are under low or high time pressure, and two-sided messages are more persuasive than one-sided messages when low-NFC individuals are under moderate time pressure. © 2011 The Author.

Biological soil crusts, comprising assemblages of cyanobacteria, fungi, lichens and mosses, are common in dryland areas and are important elements in these ecosystems. Increasing N deposition has led to great changes in community structure and function in desert ecosystems worldwide. However, it is unclear how moss crusts respond to increased atmospheric N deposition, especially in terms of growth and physiological parameters. The aim of this study was to understand how Syntrichia caninervis, a dominant species in moss crusts in many northern hemisphere desert ecosystems, responds to added N. The population and shoot growth, and physiological responses of S. caninervis to six different doses of simulated N deposition (0, 0·3, 0·5, 1·0, 1·5 and 3·0 g N m(-2) year(-1)) were studied over a 3 year period. Low amounts of added N increased shoot length and leaf size, whereas high doses reduced almost all growth parameters. Moss shoot density increased, but population biomass decreased with high N. Low N augmented chlorophyll b, total chlorophyll content and soluble protein concentrations, but not chlorophyll a or chlorophyll fluorescence. High N was detrimental to all these indices. Soluble sugar concentration declined with increased N, but proline concentration was not affected significantly. Antioxidant enzyme activities generally decreased with low N additions and increased with high doses of simulated N deposition. Low amounts of added N (0-0·5 g N m(-2) year(-1)) may enhance moss growth and vitality, while higher amounts have detrimental effects. © The Author 2016.

Cardona, Genís; Sanz, Joan P

2014-09-01

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

Numerical investigation of cavitation flow in journal bearing geometry

NASA Astrophysics Data System (ADS)

Riedel, M.; Schmidt, M.; Stücke, P.

2013-04-01

The appearance of cavitation is still a problem in technical and industrial applications. Especially in automotive internal combustion engines, hydrodynamic journal bearings are used due to their favourable wearing quality and operating characteristics. Cavitation flows inside the bearings reduces the load capacity and leads to a risk of material damages. Therefore an understanding of the complex flow phenomena inside the bearing is necessary for the design development of hydrodynamic journal bearings. Experimental investigations in the fluid domain of the journal bearing are difficult to realize founded by the small dimensions of the bearing. In the recent years more and more the advantages of the computational fluid dynamics (CFD) are used to investigate the detail of the cavitation flows. The analysis in the paper is carried out in a two-step approach. At first an experimental investigation of journal bearing including cavitation is selected from the literature. The complex numerical model validated with the experimental measured data. In a second step, typically design parameters, such as a groove and feed hole, which are necessary to distribute the oil supply across the gap were added into the model. The paper reflects on the influence of the used design parameters and the variation of the additional supply flow rate through the feed hole regarding to cavitation effects in the bearing. Detailed pictures of the three-dimensional flow structures and the cavitation regions inside the flow film of the bearing are presented.

Enhancing AstroInformatics and Science Discovery from Data in Journal Articles

Mazzarella, Joseph

2011-05-01

Traditional methods of publishing scientific data and metadata in journal articles are in need of major upgrades to reach the full potential of astronomical databases and astroinformatics techniques to facilitate semi-automated, and eventually autonomous, methods of science discovery. I will review a growing collaboration involving the NASA/IPAC Extragalactic Database (NED), the Astrophysics Data System (ADS), the Virtual Astronomical Observatory (VAO), the AAS Journals and IOP, and the Data Conservancy that is aimed toward transforming the methodology used to publish, capture and link data associated with astrophysics journal articles. We are planning a web-based workflow to assist astronomers during the publication of journal articles. The primary goals are to facilitate the application of structure and standards to (meta)data, reduce errors, remove ambiguities in the identification of astrophysical objects and regions of sky, capture and preserve the images and spectral data files used to make plots, and accelerate the ingestion of the data into relevant repositories, search engines and integration services. The outcome of this community wide effort will address a recent public policy mandate to publish scientific data in open formats to allow reproducibility of results and to facilitate new discoveries. Equally important, this work has the potential to usher in a new wave of science discovery based on seamless connectivity between data relationships that are continuously growing in size and complexity, and increasingly sophisticated data visualization and analysis applications.

Direct-to-Consumer Broadcast Advertisements for Pharmaceuticals: Off-Label Promotion and Adherence to FDA Guidelines.

PubMed

Klara, Kristina; Kim, Jeanie; Ross, Joseph S

2018-05-01

Direct-to-consumer (DTC) advertisements for prescription drugs in the United States are regulated by the Food and Drug Administration (FDA). Off-label promotion, or the advertisement of a drug for an indication not approved by the FDA, is prohibited. Our objective was to examine the presence of off-label promotion in broadcast DTC ads and to assess their adherence to FDA guidelines mandating fair balance in presentation of risks and benefits and prohibiting misleading advertisement claims. All English-language broadcast DTC ads for prescription drugs that aired in the United States from January 2015 to July 2016 were obtained from AdPharm, an online collection of healthcare advertisements. Ad length was measured and adherence to FDA guidelines was assessed for several categories: key regulatory items, indicators of false or misleading ads, and indicators of fair balance in presentation of risks and benefits. Our sample included 97 unique DTC ads, representing 60 unique drugs and 67 unique drug-indication combinations. No ads described drug risks quantitatively, whereas drug efficacy was presented quantitatively in 25 (26%) ads. Thirteen (13%) ads, all for diabetes medications, suggested off-label uses for weight loss and blood pressure reduction. The most commonly advertised drugs were indicated for the treatment of inflammatory conditions (n = 12; 18%), diabetes or diabetic neuropathy (n = 11; 16%), bowel or bladder dysfunction (n = 6; 9%), and infections or allergic reaction (n = 6; 9%). More than three-quarters (n = 51; 76%) advertised drugs to treat chronic conditions. Few broadcast DTC ads were fully compliant with FDA guidelines. The overall quality of information provided in ads was low, and suggestions of off-label promotion were common for diabetes medications. The impact of current DTC ads and off-label marketing on patient and prescriber decisions merits further scrutiny.

Prevalence and predictors of advance directives in Australia.

Advance care planning is regarded as integral to better patient outcomes, yet little is known about the prevalence of advance directives (AD) in Australia. To determine the prevalence of AD in the Australian population. A national telephone survey about estate and advance planning. Sample was stratified by age (18-45 and >45 years) and quota sampling occurred based on population size in each state and territory. Fourteen per cent of the Australian population has an AD. There is state variation with people from South Australia and Queensland more likely to have an AD than people from other states. Will making and particularly completion of a financial enduring power of attorney are associated with higher rates of AD completion. Standard demographic variables were of limited use in predicting whether a person would have an AD. Despite efforts to improve uptake of advance care planning (including AD), barriers remain. One likely trigger for completing an AD and advance care planning is undertaking a wider future planning process (e.g. making a will or financial enduring power of attorney). This presents opportunities to increase advance care planning, but steps are needed to ensure that planning, which occurs outside the health system, is sufficiently informed and supported by health information so that it is useful in the clinical setting. Variations by state could also suggest that redesign of regulatory frameworks (such as a user-friendly and well-publicised form backed by statute) may help improve uptake of AD. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

Citation analysis elucidates patterns of information consumption within professional communities. The aim of this study was to analyze the citations of 87 Spanish medical journals by calculating their impact factors and immediacy indices for 2001, and to estimate the importance of Archivos de Bronconeumología within the framework of Spanish medicine. Eighty-seven Spanish medical journals were included. All were listed in the Spanish Medical Index (Indice Medico Español) and in at least one of the following databases: MEDLINE, BIOSIS, EMBASE, or Science Citation Index. References to articles from 1999 through 2001 in citable articles from 2001 were analyzed. Using the method of the Institute for Scientific Information, we calculated the national impact factor and immediacy index for each journal. The journals with the highest national impact factors were Revista Española de Quimioterapia (0.894), Medicina Clínica (0.89), and Archivos de Bronconeumología (0.732). The self-citation percentage of Archivos de Bronconeumología was 18.3% and the immediacy index was 0.033. The impact factor obtained by Archivos de Bronconeumología confirms its importance in Spanish medicine and validates its inclusion as a source journal in Science Citation Index and Journal Citation Report.

The toxicity of tau in Alzheimer disease: turnover, targets and potential therapeutics.

2011-08-01

It has been almost 25 years since the initial discovery that tau was the primary component of the neurofibrillary tangles (NFTs) in Alzheimer disease (AD) brain. Although AD is defined by both β-amyloid (Aβ) pathology (Aβ plaques) and tau pathology (NFTs), whether or not tau played a critical role in disease pathogenesis was a subject of discussion for many years. However, given the increasing evidence that pathological forms of tau can compromise neuronal function and that tau is likely an important mediator of Aβ toxicity, there is a growing awareness that tau is a central player in AD pathogenesis. In this review we begin with a brief history of tau, then provide an overview of pathological forms of tau, followed by a discussion of the differential degradation of tau by either the proteasome or autophagy and possible mechanisms by which pathological forms of tau may exert their toxicity. We conclude by discussing possible avenues for therapeutic intervention based on these emerging themes of tau's role in AD. © 2011 The Authors Journal compilation © 2011 Foundation for Cellular and Molecular Medicine/Blackwell Publishing Ltd.

Extensive recent research supports a proposal that a new eating disorder, binge eating disorder (BED), be included in DSM-IV. BED criteria define a relatively pure group of individuals who are distressed by recurrent binge eating who do not exhibit the compensatory features of bulimia nervosa. This large number of patients currently can only be diagnosed as eating disorder not otherwise specified (EDNOS). Recognizing this new disorder will help stimulate research and clinical programs for these patients. Fairburn et al.'s critique of BED fails to acknowledge the large body of knowledge that indicates that BED represents a distinct and definable subgroup of eating disordered patients and that the diagnosis provides useful information about psychopathology, prognosis, and outcome (Fairburn, Welch, & Hay [in press]. The classification of recurrent overeating: The "binge eating disorder" proposal. International Journal of Eating Disorders.) Against any reasonable standard for adding a new diagnosis to DSM-IV, BED meets the test.

Is April to July runoff really decreasing in the Western United States?

USGS Publications Warehouse

Wahl, Kenneth L.

1991-01-01

Global warming has been the topic of a great deal of heated discussion and debate in recent years, both in the lay press and in scientific journals. The debate is about whether we are beginning to detect signs of a buildup of greenhouse gases on a global scale. A major part of the debate concerns the possible effects on climate and on the future availability of water resources. The ongoing drought in California has added impetus to the debate, serving notice of the serious consequences of any prolonged decrease in the availability of adequate water supplies. This paper has three primary objectives: (1) To evaluate the ramifications of using fractional runoff rather than total runoff to define trends in runoff; (2) to analyze additional streamflow data for the presence and extent of trends in annual and seasonal runoff volume for the conterminous Western United States; and (3) to examine the influence of the current California drought on indicators of trend.

The role of qualitative research in psychological journals.

PubMed

Kidd, Sean A

2002-03-01

The acceptance of qualitative research in 15 journals published and distributed by the American Psychological Association (APA) was investigated. This investigation included a PsycINFO search using the keyword qualitative, an analysis of 15 APA journals for frequency of qualitative publication, a content analysis of the journal descriptions, and the results of qualitative interviews with 10 of the chief editors of those journals. The results indicate that there exists a substantial amount of interest in the potential contribution of qualitative methods in major psychological journals, although this interest is not ubiquitous, well defined, or communicated. These findings highlight the need for APA to state its position regarding the applicability of qualitative methods in the study of psychology.

There is growing awareness of the coexistence of Alzheimer's disease and cerebrovascular disease (AD+CVD), however, due to lack of well-defined criteria and treatment guidelines AD+CVD may be underdiagnosed in Asia. Sixteen dementia specialists from nine Asia Pacific countries completed a survey in September 2014 and met in November 2014 to review the epidemiology, diagnosis and treatment of AD+CVD in Asia. A consensus was reached by discussion, with evidence provided by published studies when available. AD accounts for up to 60% and AD+CVD accounts for 10-20% of all dementia cases in Asia. The reasons for underdiagnosis of AD+CVD include lack of awareness as a result of a lack of diagnostic criteria, misdiagnosis as vascular dementia or AD, lack of diagnostic facilities, resource constraints and cost of investigations. There is variability in the tools used to diagnose AD+CVD in clinical practice. Diagnosis of AD+CVD should be performed in a stepwise manner of clinical evaluation followed by neuroimaging. Dementia patients should be assessed for cognition, behavioural and psychological symptoms, functional staging and instrumental activities of daily living. Neuroimaging should be performed using computed tomography or magnetic resonance imaging. The treatment goals are to stabilize or slow progression as well as to reduce behavioural and psychological symptoms, improve quality of life and reduce disease burden. First-line therapy is usually an acetylcholinesterase inhibitor such as donepezil. AD+CVD is likely to be under-recognised in Asia. Further research is needed to establish the true prevalence of this treatable and potentially preventable disease. © 2016 The Association for the Publication of the Journal of Internal Medicine.

Journal rankings by citation analysis in health sciences librarianship.

Fang, M L

1989-01-01

The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. PMID:2655785

Integrative review of international nursing research in Mainland China.

Li, M; Wei, L; Liu, H; Tang, L

2009-03-01

Nursing research in Mainland China is divided into two parts: domestic nursing research, comprising all publications in Chinese; and international nursing research, comprising all publications in English. Domestic nursing research has been developing rapidly, demonstrated by the increase in new national or regional journals and publications. However, little is known about the extent of international research. To outline the development of international nursing research publications in Mainland China and to provide suggestions for future development. All of the papers were retrieved from PubMed. The key search phase was 'China or P.R.China NOT Hong Kong NOT Taiwan NOT Macao [AD]', with the limits of 'English', 'nursing journals' as well as the published date up to '2007/09/30'. PubMed recorded 57 English papers that were originally conducted in Mainland China during the search period from 1989 to 30 September 2007. Thirty-seven of the total 57 (65%) publications were contributed by Beijing, Shanghai and Hubei. Forty-four of the 57 publications were conducted with collaborators from Hong Kong, the USA, the UK and Canada. Thirteen publications were funded by international societies, while only three were funded by the Chinese government. The research topics mainly focused on clinical research, nursing education and nursing management. This study indicates that international nursing research has been growing slowly in Mainland China along with provincial variations. The suggestions to improve nursing research include the reform of nursing education, the enhancement of the collaboration with the international societies and the establishment of research priorities.

Statistical relationships between journal use and research output at academic institutions in South Korea.

PubMed

Jung, Youngim; Kim, Jayhoon; So, Minho; Kim, Hwanmin

In this study, we analysed the statistical association between e-journal use and research output at the institution level in South Korea by performing comparative and diachronic analyses, as well as the analysis by field. The datasets were compiled from four different sources: national reports on research output indicators in science fields, two statistics databases on higher education institutions open to the public, and e-journal usage statistics generated by 47 major publishers. Due to the different data sources utilized, a considerable number of missing values appeared in our datasets and various mapping issues required corrections prior to the analysis. Two techniques for handling missing data were applied and the impact of each technique was discussed. In order to compile the institutional data by field, journals were first mapped, and then the statistics were summarized according to subject field. We observed that e-journal use exhibited stronger correlations with the number of publications and the times cited, in contrast to the number of undergraduates, graduates, faculty members and the amount of research funds, and this was the case regardless of the NA handling method or author type. The difference between the maximum correlation for the amount of external research funding with two average indicators and that of the correlation for e-journal use were not significant. Statistically, the accountability of e-journal use for the average times cited per article and the average JIF was quite similar with external research funds. It was found that the number of e-journal articles used had a strong positive correlation (Pearson's correlation coefficients of r  > 0.9, p  < 0.05) with the number of articles published in SCI(E) journals and the times cited regardless of the author type, NA handling method or time period. We also observed that the top-five institutions in South Korea, with respect to the number of publications in SCI(E) journals, were generally across a balanced range of academic activities, while producing significant research output and using published material. Finally, we confirmed that the association of e-journal use with the two quantitative research indicators is strongly positive, even for the analyses by field, with the exception of the Arts and Humanities.

2007-01-01

Background Although peer review is widely considered to be the most credible way of selecting manuscripts and improving the quality of accepted papers in scientific journals, there is little evidence to support its use. Our aim was to estimate the effects on manuscript quality of either adding a statistical peer reviewer or suggesting the use of checklists such as CONSORT or STARD to clinical reviewers or both. Methodology and Principal Findings Interventions were defined as 1) the addition of a statistical reviewer to the clinical peer review process, and 2) suggesting reporting guidelines to reviewers; with “no statistical expert” and “no checklist” as controls. The two interventions were crossed in a 2×2 balanced factorial design including original research articles consecutively selected, between May 2004 and March 2005, by the Medicina Clinica (Barc) editorial committee. We randomized manuscripts to minimize differences in terms of baseline quality and type of study (intervention, longitudinal, cross-sectional, others). Sample-size calculations indicated that 100 papers provide an 80% power to test a 55% standardized difference. We specified the main outcome as the increment in quality of papers as measured on the Goodman Scale. Two blinded evaluators rated the quality of manuscripts at initial submission and final post peer review version. Of the 327 manuscripts submitted to the journal, 131 were accepted for further review, and 129 were randomized. Of those, 14 that were lost to follow-up showed no differences in initial quality to the followed-up papers. Hence, 115 were included in the main analysis, with 16 rejected for publication after peer review. 21 (18.3%) of the 115 included papers were interventions, 46 (40.0%) were longitudinal designs, 28 (24.3%) cross-sectional and 20 (17.4%) others. The 16 (13.9%) rejected papers had a significantly lower initial score on the overall Goodman scale than accepted papers (difference 15.0, 95% CI: 4.6–24.4). The effect of suggesting a guideline to the reviewers had no effect on change in overall quality as measured by the Goodman scale (0.9, 95% CI: −0.3–+2.1). The estimated effect of adding a statistical reviewer was 5.5 (95% CI: 4.3–6.7), showing a significant improvement in quality. Conclusions and Significance This prospective randomized study shows the positive effect of adding a statistical reviewer to the field-expert peers in improving manuscript quality. We did not find a statistically significant positive effect by suggesting reviewers use reporting guidelines. PMID:17389922

increasing number of persons reach very high age but few studies have investigated their drug use patterns. to compare drug use among persons with Alzheimer's disease (AD) aged ≥90 years to persons without AD with similar age and to younger persons with AD. register-based data were from the MEDALZ cohort including all community-dwelling persons diagnosed with AD 2005-11 in Finland. They were identified from Special Reimbursement register. One comparison person without AD was matched with age-, gender- and region of residence. Persons with AD were divided to those aged ≥90 years (N = 3,319) and <90 years (N = 63,896) at the time of AD diagnoses. Drug use was analysed during a 6-month period after AD diagnosis. Logistic regression models were constructed to compare prevalence of drug use. compared to comparison persons without AD with similar age, persons with AD aged ≥90 years were more likely to use antipsychotics (comorbidity adjusted odds ratio [aOR] 4.84, 95% CI 4.07-5.75; CI, confidence intervals) and antidepressants (aOR 2.45, 95% CI 2.14-2.80). In addition, persons with AD used more likely preventive drugs such as statins (aOR 1.20, 95% CI 1.04-1.38) and bisphosphonates (aOR 1.33, 95% CI 1.13-1.57). Compared to younger persons with AD, those aged ≥90 years were more likely to use psychotropic drugs (55.6% vs. 48.4%, aOR 1.30, 95% CI 1.21-1.39), including antipsychotics (aOR 1.40, 95% CI 1.28-1.52) and BZDRs (aOR 1.34, 95% CI 1.25-1.45). the vulnerable oldest persons with AD receive a substantial burden of psychotropics. © The Author 2016.

De Groote, Sandra L.; Dorsch, Josephine L.

2003-01-01

Purpose: This research sought to determine use of online biomedical journals and databases and to assess current user characteristics associated with the use of online resources in an academic health sciences center. Setting: The Library of the Health Sciences–Peoria is a regional site of the University of Illinois at Chicago (UIC) Library with 350 print journals, more than 4,000 online journals, and multiple online databases. Methodology: A survey was designed to assess online journal use, print journal use, database use, computer literacy levels, and other library user characteristics. A survey was sent through campus mail to all (471) UIC Peoria faculty, residents, and students. Results: Forty-one percent (188) of the surveys were returned. Ninety-eight percent of the students, faculty, and residents reported having convenient access to a computer connected to the Internet. While 53% of the users indicated they searched MEDLINE at least once a week, other databases showed much lower usage. Overall, 71% of respondents indicated a preference for online over print journals when possible. Conclusions: Users prefer online resources to print, and many choose to access these online resources remotely. Convenience and full-text availability appear to play roles in selecting online resources. The findings of this study suggest that databases without links to full text and online journal collections without links from bibliographic databases will have lower use. These findings have implications for collection development, promotion of library resources, and end-user training. PMID:12883574

2007-01-01

Objective: To explore journal quality as perceived by clinicians and researchers in clinical neurology. Methods: A survey was conducted from August 2003 to January 2004. Ratings for 41 selected clinical neurology journals were obtained from 254 members of the World Federation of Neurology (1,500 solicited; response rate 17%). Participants provided demographic information and rated each journal on a 5-point Likert scale. Average ratings for all journals were compared with the ISI's journal impact factors. Ratings for each journal were also compared across geographic regions and respondent publication productivity. Results: The top 5 journals were rated much more highly than the others, with mean ratings greater than 4. Mean journal ratings were highly correlated with journal impact factors (r = 0.67). Most of the top 10 journal ratings were consistent across the subgroups of geographic regions and journal paper productivity. However, significant differences among the different geographical regions and respondent productivity groups were also found for a few journals. Conclusions: The results provide valuable insight on how neurological experts perceive journals in clinical neurology. These results will likely aid researchers and clinicians in identifying potentially desirable research outlets and indicate journal status for editors. Likewise, biomedical librarians may use these results for serials collection development. PMID:17252069

While it is well known that discourse-related language functions are impaired in the dementia phase of Alzheimer's Disease (AD), the presymptomatic temporal course of discourse dysfunction are not known earlier in the course of AD. To conduct discourse-related studies in this phase of AD, validated psychometric instruments are needed. This study investigates the latent structure, validity, and test-retest stability of discourse measures in a late-middle-aged normative group who are relatively free from sporadic AD risk factors. Using a normative sample of 399 participants (mean age = 61), exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were conducted on 18 measures of connected language derived from picture descriptions. Factor invariance across sex and family history and longitudinal test-retest stability measures were calculated. The EFA revealed a four-factor solution, consisting of semantic, syntax, fluency, and lexical constructs. The CFA model substantiated the structure, and factors were invariant across sex and parental history of AD status. Test-retest stability measures were within acceptable ranges. Results confirm a factor structure that is invariant across sex and parental AD history. The factor structure could be useful in similar cohorts designed to detect early language decline in investigations of preclinical or clinical AD or as outcome measures in clinical prevention trials. © The Author 2017.

Atopic dermatitis induces the expansion of thymus-derived regulatory T cells exhibiting a Th2-like phenotype in mice.

Atopic dermatitis (AD) is a widespread inflammatory skin disease with an early onset, characterized by pruritus, eczematous lesions and skin dryness. This chronic relapsing disease is believed to be primarily a result of a defective epidermal barrier function associated with genetic susceptibility, immune hyper-responsiveness of the skin and environmental factors. Although the important role of abnormal immune reactivity in the pathogenesis of AD is widely accepted, the role of regulatory T cells (Tregs) remains elusive. We found that the Treg population is expanded in a mouse model of AD, i.e. mice topically treated with vitamin D3 (VitD). Moreover, mice with AD-like symptoms exhibit increased inducible T-cell costimulator (ICOS)-, cytotoxic T-lymphocyte antigen-4 (CTLA-4)- and Glycoprotein-A repetitions predominant receptor (GARP)-expressing Tregs in skin-draining lymph nodes. Importantly, the differentiation of Tregs into thymus-derived Tregs is favoured in our mouse model of AD. Emigrated skin-derived dendritic cells are required for Treg induction and Langerhans cells are responsible for the biased expansion of thymus-derived Tregs . Intriguingly, thymus-derived Tregs isolated from mice with AD-like symptoms exhibit a Th2 cytokine profile. Thus, AD might favour the expansion of pathogenic Tregs able to produce Th2 cytokines and to promote the disease instead of alleviating symptoms. © 2016 The Authors.

Sharapova, Olga A; Yurkova, Maria S; Fedorov, Alexey N

2016-02-01

We have developed a fusion system for reliable production of insoluble hydrophobic proteins in soluble stable forms. A carrier is thermophilic minichaperone, GroEL apical domain (GrAD), a 15 kDa monomer able to bind diverse protein substrates. The Met-less variant of GrAD has been made for further convenient use of Met-specific CNBr chemical cleavage, if desired. The Met-less GrAD retained stability and solubility of the original protein. Target polypeptides can be fused to either C-terminus or N-terminus of GrAD. The system has been tested with two unrelated insoluble proteins fused to the C-terminus of GrAD. One of the proteins was also fused to GrAD N-terminus. The fusions formed inclusion bodies at 25°C and above and were partly soluble only at lower expression temperatures. Most importantly, however, after denaturation in urea, all fusions without exception were completely renatured in soluble stable forms that safely survived freezing-thawing as well as lyophilization. All fusions for both tested target proteins retained solubility at high concentrations for days. Functional analysis revealed that a target protein may retain functionality in the fusion. Convenience features include potential thermostability of GrAD fusions, capacity for chemical and enzymatic cleavage of a target and His6 tag for purification. © The Author 2015.

Compassionate Love in Individuals With Alzheimer's Disease and Their Spousal Caregivers: Associations With Caregivers' Psychological Health.

PubMed

Monin, Joan K; Schulz, Richard; Feeney, Brooke C

2015-12-01

To examine whether compassionate love in both individuals with Alzheimer's disease (AD) and their spousal caregivers related to less caregiving burden, more positive caregiving appraisals, and less depressive symptoms for caregivers. Fifty-eight individuals with AD and their spousal caregivers participated in interviews in which both partners reported their compassionate love for their partner, and caregivers self-reported burden, positive appraisals of caregiving, and depressive symptoms. As hypothesized, both AD individuals' and caregivers' compassionate love were associated with less burden and more positive appraisals of caregiving. Also, care givers' compassionate love mediated the association between AD individuals' compassionate love and caregivers' burden as well as the association between AD individuals' compassionate love and caregivers' positive appraisals of caregiving. Finally, there was a marginally significant association between caregivers' compassionate love and less caregiver depressive symptoms. Results suggest that AD individuals' compassionate love is related to compassionate love in caregivers, which in turn relates to reduced burden but not significantly less depressive symptoms for caregivers. Assessing caregivers' and AD individuals' feelings of compassionate love may be useful in identifying caregivers who are resilient and those who are at a heightened risk for caregiving burden. Also, interventions that enhance both partners' compassionate love may benefit caregivers. © The Author 2014. Published by Oxford University Press on behalf of The Gerontological Society of America.

Wild fires are an ecological disturbance agent across ecosystems, driving vegetation dynamics and resulting in disruption of habitats (Moritz et al. 2014).We analyze pollen and spores as proxies for vegetation composition, structure and agricultural activity, microscopic charcoal as a proxy for fire activity, and spheroidal carbonaceous particles (SCPs or soots) as a proxy for fossil fuel combustion which preserve in ice cores over millennia (Eichler et al. 2011).Our high-alpine ice core (4452 m a.s.l.) from Colle Gnifetti, Swiss Alps is located in the center of Western Europe, thus allowing to assess vegetation and societal responses to climatic change and wildfire disturbance on a subcontinental scale. The record covers the last millennium with an excellent chronological control (Jenk et al. 2009, Sigl et al. 2009), particularly over the most recent 200 years - the period that experienced important climatic changes and an increasing globalization of economy.The Colle Gnifetti record reflects large scale impacts such as extreme weather, societal innovations, agricultural crises and pollution of the industrial period in Western Europe. Pollution tracers occur in the record as early as 1750 AD and coincide with the shift to large-scale maize production in Northern Italy and with increased fire activity. Our multiproxy record may allow desentagling the role of climate and humans for vegetation composition and biomass burning. The attribution of causes may significantly advance our understanding of future vegetation and fire dynamics under global change conditions. To our knowledge we present the first long-term high-resolution palynological record of a high elevation ice core in Europe.REFERENCESEichler et al.

Anaerobic digestion (AD) is an attractive wastewater treatment technology, leading to the generation of recoverable biofuel (methane). Most industrial AD applications, carry excessive heating costs, however, as AD reactors are commonly operated at mesophilic temperatures while handling waste streams discharged at ambient or cold temperatures. Consequently, low-temperature AD represents a cost-effective strategy for wastewater treatment. The comparative investigation of key microbial groups underpinning laboratory-scale AD bioreactors operated at 37, 15 and 7°C was carried out. Community structure was monitored using 16S rRNA clone libraries, while abundance of the most prominent methanogens was investigated using qPCR. In addition, metaproteomics was employed to access the microbial functions carried out in situ. While δ-Proteobacteria were prevalent at 37°C, their abundance decreased dramatically at lower temperatures with inverse trends observed for Bacteroidetes and Firmicutes. Methanobacteriales and Methanosaeta were predominant at all temperatures investigated while Methanomicrobiales abundance increased at 15°C compared to 37 and 7°C. Changes in operating temperature resulted in the differential expression of proteins involved in methanogenesis, which was found to occur in all bioreactors, as corroborated by bioreactors' performance. This study demonstrated the value of employing a polyphasic approach to address microbial community dynamics and highlighted the functional redundancy of AD microbiomes. © FEMS 2015.

Effects of cannabidiol interactions with Wnt/β-catenin pathway and PPARγ on oxidative stress and neuroinflammation in Alzheimer's disease.

PubMed

Vallée, Alexandre; Lecarpentier, Yves; Guillevin, Rémy; Vallée, Jean-Noël

2017-10-01

Alzheimer's disease (AD) is a neurodegenerative disease, in which the primary etiology remains unknown. AD presents amyloid beta (Aβ) protein aggregation and neurofibrillary plaque deposits. AD shows oxidative stress and chronic inflammation. In AD, canonical Wingless-Int (Wnt)/β-catenin pathway is downregulated, whereas peroxisome proliferator-activated receptor γ (PPARγ) is increased. Downregulation of Wnt/β-catenin, through activation of glycogen synthase kinase-3β (GSK-3β) by Aβ, and inactivation of phosphatidylinositol 3-kinase/Akt signaling involve oxidative stress in AD. Cannabidiol (CBD) is a non-psychotomimetic phytocannabinoid from Cannabis sativa plant. In PC12 cells, Aβ-induced tau protein hyperphosphorylation is inhibited by CBD. This inhibition is associated with a downregulation of p-GSK-3β, an inhibitor of Wnt pathway. CBD may also increase Wnt/β-catenin by stimulation of PPARγ, inhibition of Aβ and ubiquitination of amyloid precursor protein. CBD attenuates oxidative stress and diminishes mitochondrial dysfunction and reactive oxygen species generation. CBD suppresses, through activation of PPARγ, pro-inflammatory signaling and may be a potential new candidate for AD therapy. © The Author 2017.

Antitobacco advertisement components, including types of messages and advertising appeals, have not been evaluated among multinational groups. This study identified and compared the content of antismoking video ads across three countries. We reviewed 86 antismoking video advertisements for the following information: severity of the consequences of smoking, types of risks, appeals to audiences' self-efficacy, benefits of not smoking, targeted social-ecological level and types of message appeal used. Two researchers independently coded each advertisement with an average inter-coder reliability of 0.79.Analyses showed a variety of focuses: smoking-related health risks (86%), severe consequences of smoking (54.7%), self-efficacy beliefs (40.7%) and benefits of not smoking (84.9%). Compared to the United States and Taiwanese ads, Chinese ads were more likely to target at the community level (10% versus 23.3% versus 47.2%). Additionally, 55% of the United States ads used the fear approach, whereas 61.1% of Chinese ads used the social approach. Taiwanese ads were evenly distributed among both approaches. In conclusion, the countries used different targeting strategies and approaches during message delivery. Although China's neighboring country, Taiwan, has many similar cultural aspects, including the same language, they are greatly influenced by US antitobacco campaigns. As a result, Taiwan's tobacco campaigns appear to have similar components to both China and the United States. Further research is warranted to understand the reasons for each method and to examine the effectiveness of the ads in reducing smoking rates. © The Author 2016. Published by Oxford University Press.

Alzheimer's disease (AD) weighs heavily on health expenditure and is strongly associated with increasing age. Due to population aging, increasing global prevalence of AD will pose huge challenges to public health and elderly care systems in all countries across the world. This study aimed to better understand the burden of AD from a healthcare perspective. A systematic literature review of journal articles published between January 2002 and December 2012 was performed for studies conducted in France, Germany, Italy, The Netherlands, Spain, the United Kingdom (UK), and the United States of America (USA), using Medline, Embase, and the NHS Economic Evaluation Database. 3,288 references were initially retrieved, and 39 epidemiological and 66 economic publications were selected for data extraction. AD incidence rates greatly varied between countries; however, prevalence was more consistent across all included countries, ranging between 3-7%. Overall, medical costs were lower in France compared to other included countries and increased with AD severity, e.g., direct medical costs per year for mild AD ranged from 5,476 int$ in France to 27,380 int$ in Spain. Limitations, such as heterogeneous methodology and missing data, prevented the comparison of results across studies between countries or the conclusion of any trend over time. This review corroborates previous understanding that AD burden is high for both society and healthcare providers. Limitations regarding study heterogeneity restricted conclusions; further research is required. Stakeholders could benefit from new healthcare strategies addressing both epidemiological and economic aspects of AD.

To review and analyze the history and current situation of stomatological journals in China from 1949 to 2009. The data from journal database, web sites and yearbooks were collected, and the information on Chinese dental journals, national economic indicators and the development in dental disciplines from 1949 to 2009 were obtained. The dental journals numbered one kind, four issues in 1949 and 32 kinds, 204 issues in 2009. China's gross domestic product (GDP) was from 67.9 billion Yuan in 1949 to 30.067 trillion Yuan in 2008. The quantity of stomatological journals in China has increased remarkably over the past 60 years.

A framework for visual communication at Nature.

PubMed

Krause, Kelly

2016-04-25

The scientific journal Nature, published weekly since 1869, serves as an excellent case study in visual communication. While journals are becoming increasingly specialist, Nature remains firmly multidisciplinary; and unlike many scientific journals, it contains original journalism, opinion pieces, and expert analysis in addition to peer-reviewed research papers. This variety of content types-covering an extensive range of scientific disciplines-translates into a wide and varied audience, and the need to employ an equally wide variety of communication styles.For example, a research paper may employ technical language to communicate to a highly specialized audience in that field, whereas a news story on the same subject will explain the science to an educated lay audience, often adding a wider context and stripping out acronyms. Each type of piece will use a communication approach tailored for its intended audience.This is true for visual content as well: the intended audience of a scientific figure, illustration or data visualization will determine the design approach to that visual. At Nature, given the high volume of content plus high quality standards, this process is applied in a fairly systematic way, using a framework to guide creative decision-making. That framework is described here, along with a discussion of best practices for the design of research figures and graphics by context. © The Author(s) 2016.

Are Psychology Journals Anti-replication? A Snapshot of Editorial Practices.

PubMed

Martin, G N; Clarke, Richard M

2017-01-01

Recent research in psychology has highlighted a number of replication problems in the discipline, with publication bias - the preference for publishing original and positive results, and a resistance to publishing negative results and replications- identified as one reason for replication failure. However, little empirical research exists to demonstrate that journals explicitly refuse to publish replications. We reviewed the instructions to authors and the published aims of 1151 psychology journals and examined whether they indicated that replications were permitted and accepted. We also examined whether journal practices differed across branches of the discipline, and whether editorial practices differed between low and high impact journals. Thirty three journals (3%) stated in their aims or instructions to authors that they accepted replications. There was no difference between high and low impact journals. The implications of these findings for psychology are discussed.

A direct comparison of popular models of normal memory loss and Alzheimer's disease in samples of African Americans, Mexican Americans, and refugees and immigrants from the former Soviet Union.

To understand how people differentiate normal memory loss from Alzheimer's disease (AD) by investigating cultural models of these conditions. Ethnographic interviews followed by a survey. Cultural consensus analysis was used to test for the presence of group models, derive the "culturally correct" set of beliefs, and compare models of normal memory loss and AD. Chicago, Illinois. One hundred eight individuals from local neighborhoods: African Americans, Mexican Americans, and refugees and immigrants from the former Soviet Union. Participants responded to yes-or-no questions about the nature and causes of normal memory loss and AD and provided information on ethnicity, age, sex, acculturation, and experience with AD. Groups held a common model of AD as a brain-based disease reflecting irreversible cognitive decline. Higher levels of acculturation predicted greater knowledge of AD. Russian speakers favored biological over psychological models of the disease. Groups also held a common model of normal memory loss, including the important belief that "normal" forgetting involves eventual recall of the forgotten material. Popular models of memory loss and AD confirm that patients and clinicians are speaking the same "language" in their discussions of memory loss and AD. Nevertheless, the presence of coherent models of memory loss and AD, and the unequal distribution of that knowledge across groups, suggests that clinicians should include wider circles of patients' families and friends in their consultations. These results frame knowledge as distributed across social groups rather than simply the possession of individual minds. © 2011, Copyright the Authors.

Campos, Camila H; Ribeiro, Giselle R; Rodrigues Garcia, Renata C M

Alzheimer disease (AD) can affect masticatory function, affecting oral health-related quality of life (OHRQoL). Whether oral rehabilitation with conventional removable prostheses can restore masticatory function and improve OHRQoL in these individuals is unknown. The purpose of this clinical study was to evaluate the influence of oral rehabilitation with removable prostheses on masticatory efficiency and OHRQoL in elders with and without AD. Thirty-two elders with mild AD (n=16, mean age=76.7 ±6.3 years) or without AD (n=16, mean age=75.2 ±4.4 years) were recruited. All participants first underwent masticatory efficiency and OHRQoL evaluations, and 2 months after insertion of new removable prostheses, the variables were reassessed. Masticatory efficiency was determined using the sieving method, and OHRQoL was measured by applying the Geriatric Oral Health Assessment Index (GOHAI). The data from the baseline and after insertion of the new removable prostheses were compared by paired t test. Group differences at each time point were assessed by t test (α=.05). After insertion of the new removable prostheses, masticatory efficiency and OHRQoL improved in both the elders with AD and the control. At baseline, elders with AD had lower masticatory efficiency and higher OHRQoL than controls (P<.05). After removable prosthesis insertion, elders with AD continued to show lower masticatory efficiency values than controls, but their OHRQoL was similar. Oral rehabilitation with new removable prostheses improved the masticatory efficiency and OHRQoL of elders with and without AD, although masticatory efficiency did not reach control levels in elders with AD.

Mounting evidence implicates disturbed sleep or lack of sleep as one of the risk factors for Alzheimer's disease (AD), but the extent of the risk is uncertain. We conducted a broad systematic review and meta-analysis to quantify the effect of sleep problems/disorders on cognitive impairment and AD. Original published literature assessing any association of sleep problems or disorders with cognitive impairment or AD was identified by searching PubMed, Embase, Web of Science, and the Cochrane library. Effect estimates of individual studies were pooled and relative risks (RR) and 95% confidence intervals (CI) were calculated using random effects models. We also estimated the population attributable risk. Twenty-seven observational studies (n = 69216 participants) that provided 52 RR estimates were included in the meta-analysis. Individuals with sleep problems had a 1.55 (95% CI: 1.25-1.93), 1.65 (95% CI: 1.45-1.86), and 3.78 (95% CI: 2.27-6.30) times higher risk of AD, cognitive impairment, and preclinical AD than individuals without sleep problems, respectively. The overall meta-analysis revealed that individuals with sleep problems had a 1.68 (95% CI: 1.51-1.87) times higher risk for the combined outcome of cognitive impairment and/or AD. Approximately 15% of AD in the population may be attributed to sleep problems. This meta-analysis confirmed the association between sleep and cognitive impairment or AD and, for the first time, consolidated the evidence to provide an "average" magnitude of effect. As sleep problems are of a growing concern in the population, these findings are of interest for potential prevention of AD. © Sleep Research Society 2016.

The cellular quality control system degrades abnormal or misfolded proteins and consists of three different mechanisms: the ubiquitin proteasomal system (UPS), autophagy and molecular chaperones. Any disturbance in this system causes proteins to accumulate, resulting in neurodegenerative diseases such as amyotrophic lateral sclerosis, Alzheimer's disease (AD), Parkinson's disease, Huntington's disease and prion or polyglutamine diseases. Alzheimer's disease is currently one of the most common age-related neurodegenerative diseases. However, its exact cause and pathogenesis are unknown. Currently approved medications for AD provide symptomatic relief; however, they fail to influence disease progression. Moreover, the components of the cellular quality control system represent an important focus for the development of targeted and potent therapies for managing AD. This review aims to evaluate whether existing evidence supports the hypothesis that UPS impairment causes the early pathogenesis of neurodegenerative disorders. The first part presents basic information about the UPS and its molecular components. The next part explains how the UPS is involved in neurodegenerative disorders. Finally, we emphasize how the UPS influences the management of AD. This review may help in the design of future UPS-related therapies for AD. © 2016 The Authors.

Social scientists need practical methods for harnessing large, publicly available datasets that inform the social context of aging. We describe our development of a semi-automated text coding method and use a content analysis of Alzheimer's disease (AD) and dementia portrayal on Twitter to demonstrate its use. The approach improves feasibility of examining large publicly available datasets. Machine learning techniques modeled stigmatization expressed in 31,150 AD-related tweets collected via Twitter's search API based on 9 AD-related keywords. Two researchers manually coded 311 random tweets on 6 dimensions. This input from 1% of the dataset was used to train a classifier against the tweet text and code the remaining 99% of the dataset. Our automated process identified that 21.13% of the AD-related tweets used AD-related keywords to perpetuate public stigma, which could impact stereotypes and negative expectations for individuals with the disease and increase "excess disability". This technique could be applied to questions in social gerontology related to how social media outlets reflect and shape attitudes bearing on other developmental outcomes. Recommendations for the collection and analysis of large Twitter datasets are discussed. © The Author 2017. Published by Oxford University Press on behalf of The Gerontological Society of America.

In Alzheimer disease (AD), the accumulation of amyloid beta (Aβ) begins decades before cognitive symptoms and progresses from intraneuronal material to extracellular plaques. To date, however, the precise mechanism by which the early buildup of Aβ peptides leads to cognitive dysfunction remains unknown. Here, we investigate the impact of the early Aβ accumulation on temporal and frontal lobe dysfunction. We compared the performance of McGill-R-Thy1-APP transgenic AD rats with wild-type littermate controls on a visual discrimination task using a touchscreen operant platform. Subsequently, we conducted studies to establish the biochemical and molecular basis for the behavioral alterations. It was found that the presence of intraneuronal Aβ caused a severe associative learning deficit in the AD rats. This coincided with reduced nuclear translocation and genomic occupancy of the CREB co-activator, CRTC1, and decreased production of synaptic plasticity-associated transcripts Arc, c-fos, Egr1, and Bdnf. Thus, blockade of CRTC1-dependent gene expression in the early, preplaque phase of AD-like pathology provides a molecular basis for the cognitive deficits that figure so prominently in early AD. © The Author 2016.

The lipid component of the Action to Control Cardiovascular Risk in Diabetes trial (ACCORD-Lipid) was a landmark, publicly-funded trial demonstrating that fenofibrate, when added to statin therapy, was not associated with improved cardiovascular outcomes among patients with diabetes. We performed a cross-sectional study of all articles describing results of ACCORD-Lipid in the news and biomedical literature in the 15 months following its publication. For articles published in biomedical journals, we determined whether there was an association between authors’ conflict of interests (COI) and trial interpretation. We identified 67 news and 141 biomedical journal articles discussing ACCORD-Lipid. Approximately 30% of news and biomedical journal articles described fenofibrate as ineffective, whereas nearly 20% concluded it was effective. Among articles making a recommendation, approximately 50% of news and 67% of biomedical journal articles supported continued fibrate use. Authors with COI were more likely to describe fenofibrate as effective (27.1% vs. 8.9%; relative risk [RR]=3.03, 95% confidence interval [CI], 1.22–7.50; P=0.008) and to support continued fibrate use (77.4% vs. 45.8%; RR=1.69, 95% CI, 1.07–2.67; P=0.006). ACCORD-Lipid was described inconsistently in news and biomedical journal articles, possibly creating uncertainty among patients and physicians, and COI were associated with more favorable trial interpretation.

Barriers and facilitators to the use of evidence-based best practices.

PubMed

Leasure, A Renee; Stirlen, Joan; Thompson, Charleen

2008-01-01

The continued use of healthcare interventions without an evidence base increases healthcare costs without positively impacting patient care outcomes. Reports disseminated by bodies such as the Institute of Medicine and initiatives such as the Institute for Health Care Improvement's 5 Million Lives Campaign have increased emphasis on improving outcomes. Results of a descriptive correlational study indicated that 64% of the nurses surveyed read 7 or more specialty journals, 53% read 1 or more general nursing journal, 20% did not regularly read any professional journal, and none of the nurses surveyed read a journal that was primarily dedicated to the publication of original research. Almost half of the nurses indicated that the hospital library was the nearest location to conduct searches, and 34% indicated that they did not know what literature-searching capabilities were available to them. Although knowledge in itself is not sufficient for behavior change, it is an essential prerequisite. Regular reading of journals either through personal subscriptions or access through facility libraries can encourage the adoption of new evidence through lifelong learning. Modeling and skill building in use of readily available Internet resources can serve as a mechanism to increase awareness of and skill in accessing current information. Evidence-based changes can then be empirically examined, implemented, and evaluated in examining nursing's contribution to the daily operation of the healthcare organization.

Purpose White matter hyperintensities (WMHs) are a risk factor for Alzheimer’s disease (AD). This study investigated the relationship between WMHs and white matter changes in AD using diffusion tensor imaging (DTI) and the sensitivity of each DTI index in distinguishing AD with WMHs. Subjects and Methods Forty-four subjects with WMHs were included. Subjects were classified into three groups based on the Scheltens rating scale: 15 AD patients with mild WMHs, 12 AD patients with severe WMHs, and 17 controls with mild WMHs. Fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (DR) and axial diffusivity (DA) were analyzed using the region of interest and Tract-Based Spatial Statistics methods. Sensitivity and specificity of DTI indices in distinguishing AD groups from the controls were evaluated. Results AD patients with mild WMHs exhibited differences from control subjects in most DTI indices in the medial temporal and frontal areas; however, differences in DTI indices from AD patients with mild WMHs and AD patients with severe WMHs were found in the parietal and occipital areas. FA and DR were more sensitive measurements than MD and DA in differentiating AD patients from controls, while MD was a more sensitive measurement in distinguishing AD patients with severe WMHs from those with mild WMHs. Conclusions WMHs may contribute to the white matter changes in AD brains, specifically in temporal and frontal areas. Changes in parietal and occipital lobes may be related to the severity of WMHs. DR may serve as an imaging marker of myelin deficits associated with AD. PMID:21152911

ResearchGate is no longer reliable: leniency towards ghost journals may decrease its impact on the scientific community.

Memon, Aamir Raoof

ResearchGate has been regarded as one of the most attractive academic social networking site for scientific community. It has been trying to improve user-centered interfaces to gain more attractiveness to scientists around the world. Display of journal related scietometric measures (such as impact factor, 5-year impact, cited half-life, eigenfactor) is an important feature in ResearchGate. Open access publishing has added more to increased visibility of research work and easy access to information related to research. Moreover, scientific community has been much interested in promoting their work and exhibiting its impact to others through reliable scientometric measures. However, with the growing market of publications and improvements in the field of research, this community has been victimized by the cybercrime in the form of ghost journals, fake publishers and magical impact measures. Particularly, ResearchGate more recently, has been lenient in its policies against this dark side of academic writing. Therefore, this communication aims to discuss concerns associated with leniency in ResearchGate policies and its impact of scientific community.

Atopic dermatitis (AD) is a common inflammatory skin disorder. Chronic AD lesions present hyperkeratosis, indicating a disturbed desquamation process. KLK7 is a serine protease involved in the proteolysis of extracellular corneodesmosome components, including desmocollin 1 and corneodesmosin, which leads to desquamation. KLK7 is secreted by lamellar granules and upregulated in AD lesional skin. However, despite increased KLK7 protein levels, immunostaining and electron microscopy indicated numerous corneodesmosomes remaining in the uppermost layer of the stratum corneum from AD lesions. We aimed to clarify the discrepancy between KLK7 overexpression and retention of corneodesmosomes on AD corneocytes. Western blot analysis indicated abnormal corneodesmosin degradation patterns in stratum corneum from AD lesions. The KLK activity of tape-stripped corneocytes from AD lesions was not significantly elevated in in situ zymography, which was our new attempt to detect the protease activity more precisely than conventional assays. This ineffective KLK activation was associated with impaired KLK7 secretion from lamellar granules and increased expression of LEKTI in AD. Such imbalances in protease-protease inhibitor interactions could lead to abnormal proteolysis of corneodesmosomes and compact hyperkeratosis. Upregulated expression of LEKTI might be a compensatory mechanism to prevent further barrier dysfunction in AD. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

In bioinformatic applications, computationally demanding algorithms are often parallelized to speed up computation. Nevertheless, setting up computational environments for distributed computation is often tedious. Aim of this project were the lightweight ad hoc set up and fault-tolerant computation requiring only a Java runtime, no administrator rights, while utilizing all CPU cores most effectively. The Sputnik framework provides ad hoc distributed computation on the Java Virtual Machine which uses all supplied CPU cores fully. It provides a graphical user interface for deployment setup and a web user interface displaying the current status of current computation jobs. Neither a permanent setup nor administrator privileges are required. We demonstrate the utility of our approach on feature selection of microarray data. The Sputnik framework is available on Github http://github.com/sysbio-bioinf/sputnik under the Eclipse Public License. hkestler@fli-leibniz.de or hans.kestler@uni-ulm.de Supplementary data are available at Bioinformatics online. © The Author 2014.

Little is known about the influence of different forms of added sugar intake on diet quality or their association with obesity among youth. Dietary intake was assessed by three 24-h recalls in 613 Canadian children (aged 8-10 years). Added sugars (mean of 3-day intakes) were categorized according to source (solid or liquid). Dietary intake and the Canadian Healthy Eating Index (« HEI-C ») were compared across tertiles of solid and liquid added sugars separately as were adiposity indicators (body mass index (BMI), fat mass (dual-energy X-ray absorptiometry), and waist circumference). Cross-sectional associations were examined in linear regression models adjusting for age, sex, energy intake, and physical activity (7-day accelerometer). Added sugar contributed 12% of total energy intake (204 kcal) on average, of which 78% was from solid sources. Higher consumption of added sugars from either solid or liquid source was associated with higher total energy, lower intake of micronutrients, vegetables and fruit, and lower HEI-C score. Additionally liquid sources were associated with lower intake of dairy products. A 10-g higher consumption of added sugars from liquid sources was associated with 0.4 serving/day lower of vegetables and fruit, 0.4-kg/m(2) higher BMI, a 0.5-kg higher fat mass, and a 0.9-cm higher waist circumference whereas the associations of added sugars from solid sources and adiposity indicators tended to be negative. In conclusion, higher consumption of added sugar from either solid or liquid sources was associated with lower overall diet quality. Adiposity indicators were only positively associated with added sugars from liquid sources.

Biomedical science journals in the Arab world.

Tadmouri, Ghazi O

2004-10-01

Medieval Arab scientists established the basis of medical practice and gave important attention to the publication of scientific results. At present, modern scientific publishing in the Arab world is in its developmental stage. Arab biomedical journals are less than 300, most of which are published in Egypt, Lebanon, and the Kingdom of Saudi Arabia. Yet, many of these journals do not have on-line access or are indexed in major bibliographic databases. The majority of indexed journals, however, do not have a stable presence in the popular PubMed database and their indexes are discontinued since 2001. The exposure of Arab biomedical journals in international indices undoubtedly plays an important role in improving the scientific quality of these journals. The successful examples discussed in this review encourage us to call for the formation of a consortium of Arab biomedical journal publishers to assist in redressing the balance of the region from biomedical data consumption to data production.

Hunt, Glenn E; Happell, Brenda; Chan, Sally W-C; Cleary, Michelle

2012-12-01

The journal impact factor (JIF), and how best to rate the performance of a journal and the articles they contain, are areas of great debate. The aim of this paper was to assess various ranking methods of journal quality for mental health nursing journals, and to list the top 10 articles that have received the most number of citations to date. Seven mental health nursing journals were chosen for the analysis of citations they received in 2010, as well as their current impact factors from two sources, and other data for ranking purposes. There was very little difference in the top four mental health nursing journals and their overall rankings when combining various bibliometric indicators. That said, the International Journal of Mental Health Nursing is currently the highest ranked mental health nursing journal based on JIF, but publishes fewer articles per year compared to other journals. Overall, very few articles received 50 or more citations. This study shows that researchers need to consider more than one ranking method when deciding where to send or publish their research. © 2012 The Authors.

Adding mucus to in vitro fermentation models of the large intestine shows that some genera, namely lactobacilli, are dependent on host-microbiota interactions and that they rely on mucosal layers to increase their activity. This study investigated whether this dependence on mucus is substrate dependent and to what extent other genera are impacted by the presence of mucus. Inulin and cellulose were fermented in vitro by a fecal inoculum from pig in the presence or not of mucin beads in order to compare fermentation patterns and bacterial communities. Mucins increased final gas production with inulin and shifted short-chain fatty acid molar ratios (P < 0.001). Quantitative real-time PCR analyses revealed that Lactobacillus spp. and Bifidobacterium spp. decreased with mucins, but Bacteroides spp. increased when inulin was fermented. A more in-depth community analysis indicated that the mucins increased Proteobacteria (0.55 vs 0.25%, P = 0.013), Verrucomicrobia (5.25 vs 0.03%, P = 0.032), Ruminococcaceae, Bacteroidaceae and Akkermansia spp. Proteobacteria (5.67 vs 0.55%, P < 0.001) and Lachnospiraceae (33 vs 10.4%) were promoted in the mucus compared with the broth, while Ruminococcaceae decreased. The introduction of mucins affected many microbial genera and fermentation patterns, but from PCA results, the impact of mucus was independent of the fermentation substrate. © FEMS 2015.

Study of Strongly Coupled Systems via Probe Brane Constructions

NASA Astrophysics Data System (ADS)

Chang, Han-Chih

In this thesis, we present our study towards better understanding of the strongly coupled systems with extra matter content in the fundamental representation of some prescribed global symmetry group in the quenched approximation, with the toolkit of holography via a probe brane construction. Specically, for the defect conformal systems, we unearth and quantify the phase trasition diagram, and novel supersymmetric vacua in the top-down model of the D3/D5 probe brane system. For further quantify various non-Fermi quantum liquid phases realized through the holographical probe brane construction, we then propose and verify the method to include the backreaction of entanglement entropy due to the probe branes at the leading order, which can potentially be used to detect topological phase transitions.

Phototherapy has a time-honoured place in the treatment of variety of skin diseases in adults. The use of this modality in children is limited mainly due to concerns about long-term carcinogenic potential. Only a few clinical trials have been performed on the efficacy and safety of phototherapy in children. To determine the efficacy and safety of NB-UVB phototherapy in children with atopic dermatitis (AD) and psoriasis. This is a retrospective review of the treatment outcomes of 129 children with psoriasis and AD, who were treated with NB-UVB between 1998 and 2006 at our institute. Fifty per cent of the psoriatic patients and 25% of patients with AD achieved clearance by the end of the treatment. NB-UVB phototherapy was well-tolerated, with no serious adverse effects except one doubtful case of melanoma in situ. NB-UVB may be considered as a viable therapeutic option in children with psoriasis and AD. Children who are treated by phototherapy should remain under annual dermatologic observation. To determine true carcinogenic risk of UV therapy, longer follow-up is essential. © 2010 The Authors.

Extension of the ADjoint Approach to a Laminar Navier-Stokes Solver

NASA Astrophysics Data System (ADS)

Paige, Cody

The use of adjoint methods is common in computational fluid dynamics to reduce the cost of the sensitivity analysis in an optimization cycle. The forward mode ADjoint is a combination of an adjoint sensitivity analysis method with a forward mode automatic differentiation (AD) and is a modification of the reverse mode ADjoint method proposed by Mader et al.[1]. A colouring acceleration technique is presented to reduce the computational cost increase associated with forward mode AD. The forward mode AD facilitates the implementation of the laminar Navier-Stokes (NS) equations. The forward mode ADjoint method is applied to a three-dimensional computational fluid dynamics solver. The resulting Euler and viscous ADjoint sensitivities are compared to the reverse mode Euler ADjoint derivatives and a complex-step method to demonstrate the reduced computational cost and accuracy. Both comparisons demonstrate the benefits of the colouring method and the practicality of using a forward mode AD. [1] Mader, C.A., Martins, J.R.R.A., Alonso, J.J., and van der Weide, E.

This study was conducted to replace soya bean meal with maggot meal at difference percentages. A total of 120 one-day-old broiler chicks were divided into four groups. Four diets were formulated with maggot meal to replace soya bean meal at the rate of 0%, 10%, 20% and 30% designated as A, B, C and D respectively. Feed and water were offered ad libitum during the study which lasted for 28 days. Feed intake decreased significantly in treated groups while body weight, Feed conversion ratio and dressing percentage increased significantly in group D. Apparent metabolizable energy increased significantly in the group fed 30% maggot meal; however, no significant difference was found in dry matter, crude protein, crude fibre, ether extract, ash and nitrogen free extract between the control and treated groups. The result of sensory evaluation revealed that tenderness and juiciness increased significantly in group C and B respectively. The colour and flavour were most accepted in group B and C. The results indicate that replacement of soya bean meal at the rate of 30% in broiler feed produced most favourable results.

Purpose: To begin investigating the impact of electronic journals on research processes such as information seeking, the authors conducted a pilot journal-use study to test the hypothesis that patrons use print and electronic journals differently. Methodology: We placed fifteen high-use print titles also available in electronic format behind the circulation desk; patrons were asked to complete a survey upon requesting a journal. We also conducted a parallel survey of patrons using library computers. Both surveys asked patrons to identify themselves by user category and queried them about their journal use. Results: During the month-long study, patrons completed sixty-nine surveys of electronic and ninety surveys of print journal use. Results analysis indicated that fellows, students, and residents preferred electronic journals, and faculty preferred print journals. Patrons used print journals for reading articles and scanning contents; they employed electronic journals for printing articles and checking references. Users considered electronic journals easier to access and search than print journals; however, they reported that print journals had higher quality text and figures. Discussion/Conclusion: This study is an introductory step in examining how electronic journals affect research processes. Our data revealed that there were distinct preferences in format among categories. In addition to collection management implications for libraries, these data also have implications for publishers and educators; current electronic formats do not facilitate all types of uses and thus may be changing learning patterns as well.

Seasonal variations in coral health indices reflecting autotrophic activity (chlorophyll a and zooxanthellae density), metabolic rates (RNA/DNA ratio and protein) and energy storage (ratio of storage: structural lipids or lipid ratios) were examined for two dominant Acropora species [ Acropora digitifera ( AD) and Acropora spicifera ( AS)] at Ningaloo Reef (north-western Australia). Such detailed investigation of metabolic processes is important background, with regard to understanding the vulnerability of corals to environmental change. Health indices in AD and AS were measured before and after spawning in austral autumn and winter 2010, and austral summer 2011 at six stations. Health indices showed seasonal and species-specific differences but negligible spatial differences across a reef section. For AD, autotrophic indices were negatively correlated with lipid ratios and metabolic indices. Metabolic indices were significantly higher in AS than AD. No correlation was observed between RNA/DNA ratios and lipid ratios with any autotrophic indices for AS. Lipid ratios were stable throughout the year for AS while they changed significantly for AD. For both species, indices of metabolic activity were highest during autumn, while autotrophic indices were highest in winter and summer. Results suggest that the impact of the broadcast spawning event on coral health indices at Ningaloo Reef occurred only as a backdrop to massive seasonal changes in coral physiology. The La Niña summer pattern resulted in high autotrophic indices and low metabolic indices and energy stores. Our results imply different metabolic processes in A. digitifera and A. spicifera as well as a strong impact of extreme events on coral physiology.

Atopic dermatitis, atopic eczema, or eczema? A systematic review, meta-analysis, and recommendation for uniform use of 'atopic dermatitis'.

The lack of standardized nomenclature for atopic dermatitis (AD) creates unnecessary confusion for patients, healthcare providers, and researchers. It also negatively impacts accurate communication of research in the scientific literature. We sought to determine the most commonly used terms for AD. A systematic review of the MEDLINE, EMBASE, and LILACS (1945-2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders. In MEDLINE, 33 060 were identified, of which 21 299 (64.4%) publications used the term 'AD', 15 510 (46.9%) 'eczema', and only 2471 (7.5%) AE. Most of these publications used the term AD (82.0%) or eczema (70.8%) without additional nomenclature; only 1.2% used AE alone. Few publications used the terminology 'childhood eczema', 'flexural eczema', 'infantile eczema', 'atopic neurodermatitis', or 'Besnier's prurigo'. AD was rarely used until the late 1970s, after which it became the most commonly used of the three terms and continuously increased until 2015. Atopic eczema decreased between 2008 and 2015. Atopic dermatitis was the most commonly used term in studies across almost all publication types, languages, and journals. Atopic dermatitis is the most commonly used term and appears to be increasing in popularity. Given that eczema is a nonspecific term that describes the morphological appearance of several forms of dermatitis, we strongly suggest the use of a more specific term, AD, in publications, healthcare clinician training, and patient education. Support from researchers, reviewers, and editors is key to success. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

[Which are the most influential journals, books and scientists in Latin American biology?].

PubMed

Monge-Nájera, Julián; Benavides-Varela, Catalina; Morera, Bernal

2004-03-01

A survey was distributed by e-mail to 553 biologists who study the Neotropics, in order to identify the journals, books and researchers with the greatest influence over Latin American biology. The biologists' database of the Revista de Biología Tropical was used to obtain their addresses. One third of them answered. The Revista de Biología Tropical is considered the most influential journal in the region. The majority of other influential journals are published in developed countries. The thematic distribution of answers, as well as independent assessments found in the literature, indicate that these and other survey results are not biased by the use of the journal's database. By subject, marine and ecological journals are the most influential. In contrast with American science, there are no researchers or books that clearly dominate the field. These results hint to the subjectivity of many awards and qualifications and possibly reflect a lack of tradition regarding appearance of local scientists in the mass media, the small capacity of world wide diffusion for local research and the low priority of science in the Iberoamerican culture. Latin American journals should improve, specially through efficient communication with authors, stringent rejection of inferior manuscripts and through widespread and timely distribution. The marked dominance by male researchers may reflect the lower number of women in the field, and social inequality. Despite the absence of "superstars", there was a correlation: most scientists in the "list of outstanding researchers" were from large countries. The publication of the most influential journal in one of the smallest countries of the region might reflect the relatively long period of existence of the Revista (half a century), the lack of other alternatives in the region and the journal's inclusion in international indices. Recommendations for Latin American science include a selection of the best journals to receive financial support and the establishment, with help from the mass media, of a group of selected researchers as role models for the new generations.

Using architectures for semantic interoperability to create journal clubs for emergency response

In certain types of 'slow burn' emergencies, careful accumulation and evaluation of information can offer a crucial advantage. The SARS outbreak in the first decade of the 21st century was such an event, and ad hoc journal clubs played a critical role in assisting scientific and technical responders in identifying and developing various strategies for halting what could have become a dangerous pandemic. This research-in-progress paper describes a process for leveraging emerging semantic web and digital library architectures and standards to (1) create a focused collection of bibliographic metadata, (2) extract semantic information, (3) convert it to the Resource Descriptionmore » Framework /Extensible Markup Language (RDF/XML), and (4) integrate it so that scientific and technical responders can share and explore critical information in the collections.« less

What's with all this peer-review stuff anyway?

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

2010-01-01

The Journal of Physical Security was ostensibly started to deal with a perceived lack of peer-reviewed journals related to the field of physical security. In fact, concerns have been expressed that the field of physical security is scarcely a field at all. A typical, well-developed field might include the following: multiple peer-reviewed journals devoted to the subject, rigor and critical thinking, metrics, fundamental principles, models and theories, effective standards and guidelines, R and D conferences, professional societies, certifications, its own academic department (or at least numerous academic experts), widespread granting of degrees in the field from 4-year research universities, mechanismsmore » for easily spotting 'snake oil' products and services, and the practice of professionals organizing to police themselves, provide quality control, and determine best practices. Physical Security seems to come up short in a number of these areas. Many of these attributes are difficult to quantify. This paper seeks to focus on one area that is quantifiable: the number of peer-reviewed journals dedicated to the field of Physical Security. In addition, I want to examine the number of overall periodicals (peer-reviewed and non-peer-reviewed) dedicated to physical security, as well as the number of papers published each year about physical security. These are potentially useful analyses because one can often infer how healthy or active a given field is by its publishing activity. For example, there are 2,754 periodicals dedicated to the (very healthy and active) field of physics. This paper concentrates on trade journal versus peer-reviewed journals. Trade journals typically focus on practice-related topics. A paper appropriate for a trade journal is usually based more on practical experience than rigorous studies or research. Models, theories, or rigorous experimental research results will usually not be included. A trade journal typically targets a specific market in an industry or trade. Such journals are often considered to be news magazines and may contain industry specific advertisements and/or job ads. A peer-reviewed journal, a.k.a 'referred journal', in contrast, contains peer-reviewed papers. A peer-reviewed paper is one that has been vetted by the peer review process. In this process, the paper is typically sent to independent experts for review and consideration. A peer-reviewed paper might cover experimental results, and/or a rigorous study, analyses, research efforts, theory, models, or one of many other scholarly endeavors.« less

The NASA Astrophysics Data System provides access to about 1 million abstracts and 50,000 journal articles. This service is funded by NASA and is accessible world-wide through the World Wide Web free without restrictions at: http://adswww.harvard.edu We currently have on-line journals starting with 1975. We plan to extend the coverage for the journals and also include scans from observatory publications in our database. Eventually we plan to provide access to scans of the complete journal literature and as much observatory literature as possible. In order to accomplish this, we have started discussions with the preservation group at the Harvard University Library. Harvard University Library, together with the Library at the Center for Astrophysics is in the process of microfilming their collection of observatory publications. We are working together with this project to prepare for scanning the microfilms and make these scans available through the ADS. We are also collecting older journals and preparing them for scanning. We already have the Monthly Notices of the Royal Astronomical Society in hand from Volume 1, and have been promised a large part of the Astronomische Nachrichten prior to 1945. We will start scanning these volumes soon. All volumes that can be fed automatically through the scanning machine should be scanned and put on-line within the next 6 - 12 months. In order to scan volumes that are too brittle, we need additional funding. We hope to obtain additional funding to cover such scanning for 1998. In order to cover more of the astronomical literature, we need donations of astronomical literature. We have a web page that lists the volumes that we need so we can scan them. If you have any of these journals (or other astronomical literature), please contact us. the web page is at: http://adshome.harvard.edu/pubs/missing_journals.html We would appreciate any contributions, even smaller sets, since it will be more and more difficult to find complete sets.

Male smoker and non-smoker responses to television advertisements on the harms of secondhand smoke in China, India and Russia.

Mass media campaigns can play an important role in strengthening support for smoke-free policies and reducing exposure to secondhand smoke (SHS). Identifying anti-SHS advertisements that are effective in diverse cultural contexts may allow for resource sharing in low- and middle-income countries. A convenience sample of 481 male cigarette smokers and non-smokers in three high tobacco burden and culturally dissimilar countries (India, China and Russia) viewed and rated five anti-SHS ads. Multivariate logistic regression analyses were conducted for 'Message Acceptance', 'Negative Emotion', 'Perceived Effectiveness' and 'Behavioral Intentions'. Smokers and non-smokers in all countries consistently rated the strong graphic, health harm ads as the most effective, and the 'informational' ad as the least effective overall: the graphic ad 'Baby Alive' was at least 1.8 times more likely than the informational ad 'Smoke-free works' to receive positive ratings on all four outcomes (all P < 0.001). Graphic, health harm messages about SHS exposure have the greatest universal appeal and are the most effective in motivating changes in behavioral intentions. Similarity in reactions between smokers and non-smokers, and across countries, suggests that resource sharing and the use of a single graphic ad targeted at smokers and non-smokers would be cost-efficient strategies. © The Author 2014.

Conceptual fluency at test shifts recognition response bias in Alzheimer's disease: implications for increased false recognition.

2007-09-20

The presence or absence of conceptual information in pictorial stimuli may explain the mixed findings of previous studies of false recognition in patients with mild Alzheimer's disease (AD). To test this hypothesis, 48 patients with AD were compared to 48 healthy older adults on a recognition task first described by Koutstaal et al. [Koutstaal, W., Reddy, C., Jackson, E. M., Prince, S., Cendan, D. L., & Schacter D. L. (2003). False recognition of abstract versus common objects in older and younger adults: Testing the semantic categorization account. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, 499-510]. Participants studied and were tested on their memory for categorized ambiguous pictures of common objects. The presence of conceptual information at study and/or test was manipulated by providing or withholding disambiguating semantic labels. Analyses focused on testing two competing theories. The semantic encoding hypothesis, which posits that the inter-item perceptual details are not encoded by AD patients when conceptual information is present in the stimuli, was not supported by the findings. In contrast, the conceptual fluency hypothesis was supported. Enhanced conceptual fluency at test dramatically shifted AD patients to a more liberal response bias, raising their false recognition. These results suggest that patients with AD rely on the fluency of test items in making recognition memory decisions. We speculate that AD patients' over reliance upon fluency may be attributable to (1) dysfunction of the hippocampus, disrupting recollection, and/or (2) dysfunction of prefrontal cortex, disrupting post-retrieval processes.

Introduction Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer’s Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer’s Disease Five Dimensions (AD-5D) derived from the QOL-AD. Methods and analysis Discrete choice experiments with duration (DCETTO) and best–worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D. Ethics and dissemination The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences. This study has ethical approval. PMID:29358437

Disrupted Intrinsic Networks Link Amyloid-β Pathology and Impaired Cognition in Prodromal Alzheimer's Disease.

Amyloid-β pathology (Aβ) and impaired cognition characterize Alzheimer's disease (AD); however, neural mechanisms that link Aβ-pathology with impaired cognition are incompletely understood. Large-scale intrinsic connectivity networks (ICNs) are potential candidates for this link: Aβ-pathology affects specific networks in early AD, these networks show disrupted connectivity, and they process specific cognitive functions impaired in AD, like memory or attention. We hypothesized that, in AD, regional changes of ICNs, which persist across rest- and cognitive task-states, might link Aβ-pathology with impaired cognition via impaired intrinsic connectivity. Pittsburgh compound B (PiB)-positron emission tomography reflecting in vivo Aβ-pathology, resting-state fMRI, task-fMRI, and cognitive testing were used in patients with prodromal AD and healthy controls. In patients, default mode network's (DMN) functional connectivity (FC) was reduced in the medial parietal cortex during rest relative to healthy controls, relatively increased in the same region during an attention-demanding task, and associated with patients' cognitive impairment. Local PiB-uptake correlated negatively with DMN connectivity. Importantly, corresponding results were found for the right lateral parietal region of an attentional network. Finally, structural equation modeling confirmed a direct influence of DMN resting-state FC on the association between Aβ-pathology and cognitive impairment. Data provide evidence that disrupted intrinsic network connectivity links Aβ-pathology with cognitive impairment in early AD. © The Author 2014. Published by Oxford University Press.

Publication data relating to a rare and obscure Japanese journal "Lansania Journal of Arachnology and Zoology" (1929-1941) are examined. Available facts, together with a substantial body of circumstantial and anecdotal evidence suggest that many planned issues, including several cited by independent sources as having been published, were not published. Some biographical data relating to the editor, Kyukichi Kishida (1888-1968), are provided. Titles of all papers known to have been published in "Lansania," with page numbers and claimed publication dates are presented, together with a list of 113 new zoological names proposed in the journal. Known library holdings of the journal worldwide are indicated. Details are provided of unpublished manuscripts in proof obtained from Kishida in the 1960s. The strong probability that some printed publication dates are inaccurate is discussed in detail.

Mediation of Family Alcoholism Risk by Religious Affiliation Types*

PubMed Central

Haber, Jon Randolph; Jacob, Theodore

2009-01-01

Objective: Religious affiliation is inversely associated with alcohol dependence (AD). Our previous findings indicated that when a religious affiliation differentiated itself from cultural norms, then high-risk adolescents (those having parents with alcoholism history) raised with these affiliations exhibited fewer AD symptoms compared with adolescents of other religious affiliations and nonreligious adolescents. The first of two studies reported here provides a needed replication of our previous findings for childhood religious affiliation using a different sample, and the second study extends examination to current religious affiliation. Method: A national sample of male and female adolescents/young adults (N = 1,329; mean age = 19.6 years) was selected who were the offspring of members of the Vietnam Era Twin Registry. Parental alcoholism, religious affiliation types, and their interactions were examined as predictors of offspring AD symptoms. Results: (1) Offspring reared with a differentiating religious affiliation during childhood exhibited significantly fewer AD symptoms as young adults; (2) offspring with current differentiating religious affiliation also exhibited fewer AD symptoms; this main effect was not weakened by adding other measures of religiousness to the model; (3) differentiating religious affiliation was correlated with both family alcoholism risk and offspring outcome, and removed the association between family alcoholism risk and offspring outcome, thus indicating that differentiating religious affiliation was at least a partial mediator of the association between family AD history risk and offspring AD outcome. Conclusions: Current results indicate that religious differentiation is an inverse mediator of alcoholism risk for offspring with or without parental AD history and regardless of the influence of other religion variables. Results replicated our previous report on religious upbringing between ages 6 and 13 years and indicated an even stronger effect when current differentiating affiliation was examined. PMID:19895764

Babu, Abraham Samuel; Veluswamy, Sundar Kumar; Rao, Pratiksha Tilak; Maiya, Arun G

2014-01-01

Clinical trial registration has become an important part of editorial policies of various biomedical journals, including a few physical therapy journals. However, the extent to which editorial boards enforce the need for trial registration varies across journals. The purpose of this study was to identify editorial policies and reporting of trial registration details in MEDLINE-indexed English-language physical therapy journals. This study was carried out using a cross-sectional design. Editorial policies on trial registration of MEDLINE-indexed member journals of the International Society of Physiotherapy Journal Editors (ISPJE) (Journal of Geriatric Physical Therapy, Journal of Hand Therapy, Journal of Neurologic Physical Therapy, Journal of Orthopaedic and Sports Physical Therapy, Journal of Physiotherapy [formerly Australian Journal of Physiotherapy], Journal of Science and Medicine in Sport, Manual Therapy, Physical Therapy, Physical Therapy in Sport, Physiotherapy, Physiotherapy Research International, Physiotherapy Theory and Practice, and Revista Brasileira de Fisioterapia) were reviewed in April 2013. Full texts of reports of clinical trials published in these journals between January 1, 2008, and December 31, 2012, were independently assessed for information on trial registration. Among the 13 journals, 8 recommended trial registration, and 6 emphasized prospective trial registration. As of April 2013, 4,618 articles were published between January 2008 and December 2012, of which 9% (417) were clinical trials and 29% (121/417) of these reported trial registration details. A positive trend in reporting of trial registration was observed from 2008 to 2012. The study was limited to MEDLINE-indexed ISPJE member journals. Editorial policies on trial registration of physical therapy journals and a rising trend toward reporting of trial registration details indicate a positive momentum toward trial registration. Physical therapy journal editors need to show greater commitment to prospective trial registration to make it a rule rather than an option.

Inequality in societies, academic institutions and science journals: Gini and k-indices

NASA Astrophysics Data System (ADS)

Ghosh, Asim; Chattopadhyay, Nachiketa; Chakrabarti, Bikas K.

2014-09-01

Social inequality is traditionally measured by the Gini-index (g). The g-index takes values from 0 to 1 where g=0 represents complete equality and g=1 represents complete inequality. Most of the estimates of the income or wealth data indicate the g value to be widely dispersed across the countries of the world: g values typically range from 0.30 to 0.65 at a particular time (year). We estimated similarly the Gini-index for the citations earned by the yearly publications of various academic institutions and the science journals. The ISI web of science data suggests remarkably strong inequality and universality (g=0.70±0.07) across all the universities and institutions of the world, while for the journals we find g=0.65±0.15 for any typical year. We define a new inequality measure, namely the k-index, saying that the cumulative income or citations of (1-k) fraction of people or papers exceed those earned by the fraction (k) of the people or publications respectively. We find, while the k-index value for income ranges from 0.60 to 0.75 for income distributions across the world, it has a value around 0.75±0.05 for different universities and institutions across the world and around 0.77±0.10 for the science journals. Apart from above indices, we also analyze the same institution and journal citation data by measuring Pietra index and median index.

The Astrophysics Data System (ADS) provides access to astronomical literature through a sophisticated search engine. Over 10,000 users retrieve almost 5 million references and read more than 25,000 full text articles per month. ADS cooperates closely with all the main astronomical journals and data centers to create and maintain a state-of-the-art digital library. The Planetary Data System (PDS) publishes high quality peer reviewed planetary science data products, defines planetary archiving standards to make products usable, and provides science expertise to users in data product preparation and use. Data products are available to users on CD media, with more than 600 CD-ROM titles in the inventory from past missions as well as the recent releases from active planetary missions and observations. The ADS and PDS serve overlapping communities and offer complementary functions. The ADS and PDS are both part of the NASA Space Science Data System, sponsored by the Office of Space Science, which curates science data products for researchers and the general public. We are in the process of connecting these two data systems. As a first step we have included entries for PDS data sets in the ADS abstract service. This allows ADS users to find PDS data sets by searching for their descriptions through the ADS search system. The information returned from the ADS links directly to the data set's entry in the PDS data set catalog. After linking to this catalog, the user will have access to more comprehensive data set information, related ancillary information, and on-line data products. The PDS on the other hand will use the ADS to provide access to bibliographic information. This includes links from PDS data set catalog bibliographic citations to ADS abstracts and on-line articles. The cross-linking between these data systems allows each system to concentrate on its main objectives and utilize the other system to provide more and improved services to the users of both systems.

Preclinical and epidemiologic studies suggest a protective effect of statins on Alzheimer disease (AD). Experimental evidence indicates that some statins can cross the blood-brain barrier, alter brain cholesterol metabolism, and may ultimately decrease the production of amyloid-β (Aβ) peptide. Despite these promising leads, clinical trials have yielded inconsistent results regarding the benefits of statin treatment in AD. Seeking to detect a biological signal of statins effect on AD, we conducted a 12-week open-label trial with simvastatin 40 mg/d and then 80 mg/d in 12 patients with AD or amnestic mild cognitive impairment and hypercholesterolemia. We quantified cholesterol precursors and metabolites and AD biomarkers of Aβ and tau in both plasma and cerebrospinal fluid at baseline and after the 12-week treatment period. We found a modest but significant inhibition of brain cholesterol biosynthesis after simvastatin treatment, as indexed by a decrease of cerebrospinal fluid lathosterol and plasma 24S-hydroxycholesterol. Despite this effect, there were no changes in AD biomarkers. Our findings indicate that simvastatin treatment can affect brain cholesterol metabolism within 12 weeks, but did not alter molecular indices of AD pathology during this short-term treatment.

Prestige versus citation volume as journal indices in cognitive neuroscience.

PubMed

Ward, Jamie

2014-01-01

In recent years, alternative measures of a journal's influence have been developed to those based on citation metrics (such as Impact Factor). This includes the Scimago Journal Rank (SJR) which is adapted from algorithms used to prioritize webpages in search engines. It is considered a measure of "prestige" insofar as it takes into account the importance of links/citations and not just their total number. Taking a sample of 38 journals from within the field of cognitive neuroscience, it is shown that SJR and Impact Factor correlate highly (r = .83) but with a few large discrepancies in rankings. This journal, Cognitive Neuroscience, fares better on the prestige-based measure than might otherwise be expected from its citation-based rank.

Zhang, Xiaoli; Zou, Jie; Le, Daniel X; Thoma, George R

Automated extraction of bibliographic data, such as article titles, author names, abstracts, and references is essential to the affordable creation of large citation databases. References, typically appearing at the end of journal articles, can also provide valuable information for extracting other bibliographic data. Therefore, parsing individual reference to extract author, title, journal, year, etc. is sometimes a necessary preprocessing step in building citation-indexing systems. The regular structure in references enables us to consider reference parsing a sequence learning problem and to study structural Support Vector Machine (structural SVM), a newly developed structured learning algorithm on parsing references. In this study, we implemented structural SVM and used two types of contextual features to compare structural SVM with conventional SVM. Both methods achieve above 98% token classification accuracy and above 95% overall chunk-level accuracy for reference parsing. We also compared SVM and structural SVM to Conditional Random Field (CRF). The experimental results show that structural SVM and CRF achieve similar accuracies at token- and chunk-levels. When only basic observation features are used for each token, structural SVM achieves higher performance compared to SVM since it utilizes the contextual label features. However, when the contextual observation features from neighboring tokens are combined, SVM performance improves greatly, and is close to that of structural SVM after adding the second order contextual observation features. The comparison of these two methods with CRF using the same set of binary features show that both structural SVM and CRF perform better than SVM, indicating their stronger sequence learning ability in reference parsing.

Authoritative parenting and issue involvement as indicators of ad recall: an empirical investigation of anti-drug ads for parents.

This investigation explores the role of authoritative parenting and issue involvement in regard to the recall of parental anti-drug ads encouraging child monitoring. In addition, the study tested whether issue involvement mediates the association between authoritative parenting and recall of parental anti-drug television ads among parents (N = 185) with adolescents in Grades 6, 7, and 8. The results indicate that (a) authoritative parenting is positively associated with favorable attitudes toward monitoring children and issue involvement regarding adolescent drug use, (b) issue involvement is associated with ad recall, (c) issue involvement mediates the relationship between authoritative parenting and ad recall, (d) ad recall is not associated with favorable attitudes toward parental monitoring, and (e) favorable attitudes regarding parental monitoring are positively associated with intentions to engage in monitoring within the next 6 months.

Impact of the CONSORT Statement endorsement in the completeness of reporting of randomized clinical trials in restorative dentistry.

The aim of this study was to assess if journal endorsement of the CONSORT Statement is associated with improved completeness of reporting of randomized controlled trials (RCTs) in restorative dentistry. RCTs in restorative dentistry published in two journals that have (Journal of Dentistry and Clinical Oral Investigations) and have not (Operative Dentistry and Journal of Prosthetic Dentistry) endorsed the CONSORT Statement were selected. We compared the completeness of reporting between comparison groups (endorsers versus non-endorsers, before versus after endorsement) using a risk ratio (RR) with a 99% confidence interval for each outcome of CONSORT 2010. Also, the risk of bias of each study was evaluated. The electronic search retrieved a total of 3701 records. After the title and abstract evaluation, 169 full texts were screened and 79 RCTs identified. Considering CONSORT-endorsing journals before and after CONSORT endorsement, six items had effect estimates indicating a relatively higher proportion of completely reported RCTs published after CONSORT endorsement. Considering CONSORT-endorsing journals compared to non-endorsing journals, twelve items indicated a relatively higher proportion of completely reported RCTs published in CONSORT-endorsing journals. In both analyses the overall evidence did not present statistical significance. Although CONSORT endorsement has been linked with some improvement in the completeness of RCTs reports in the biomedical literature, this was not reflected in the present analysis confined to restorative dentistry. More innovative and involved approaches to enhancing reported may therefore be required. Inadequate reporting of randomized controlled trials can produce important consequences for all stakeholders including waste of resources and implication on healthcare decisions. A broad understandment of the use of reporting guidelines is necessary to lead to better results. Copyright © 2017 Elsevier Ltd. All rights reserved.

A survey of authors publishing in four megajournals.

PubMed

Solomon, David J

2014-01-01

Aim. To determine the characteristics of megajournal authors, the nature of the manuscripts they are submitting to these journals, factors influencing their decision to publish in a megajournal, sources of funding for article processing charges (APCs) or other fees and their likelihood of submitting to a megajournal in the future. Methods. Web-based survey of 2,128 authors who recently published in BMJ Open, PeerJ, PLOS ONE or SAGE Open. Results. The response rate ranged from 26% for BMJ Open to 47% for SAGE Open. The authors were international, largely academics who had recently published in both subscription and Open Access (OA) journals. Across journals about 25% of the articles were preliminary findings and just under half were resubmissions of manuscripts rejected by other journals. Editors from other BMJ journals and perhaps to a lesser extent SAGE and PLOS journals appear to be encouraging authors to submit manuscripts that were rejected by the editor's journals to a megajournal published by the same publisher. Quality of the journal and speed of the review process were important factors across all four journals. Impact factor was important for PLOS ONE authors but less so for BMJ Open authors, which also has an impact factor. The review criteria and the fact the journal was OA were other significant factors particularly important for PeerJ authors. The reputation of the publisher was an important factor for SAGE Open and BMJ Open. About half of PLOS ONE and around a third of BMJ Open and PeerJ authors used grant funding for publishing charges while only about 10% of SAGE Open used grant funding for publication charges. Around 60% of SAGE Open and 32% of PeerJ authors self-funded their publication fees however the fees are modest for these journals. The majority of authors from all 4 journals were pleased with their experience and indicated they were likely to submit to the same or similar journal in the future. Conclusions. Megajournals are drawing an international group of authors who tend to be experienced academics. They are choosing to publish in megajournals for a variety of reasons but most seem to value the quality of the journal and the speed of the review/publication process. Having a broad scope was not a key factor for most authors though being OA was important for PeerJ and SAGE Open authors. Most authors appeared pleased with the experience and indicated they are likely to submit future manuscripts to the same or similar megajournal which seems to suggest these journals will continue to grow in popularity.

Andersen, Jens Peter; Skrubbeltrang, Conni; Gregersen, Hans

2010-04-26

In 2003 Aalborg Hospital became part of Aarhus University Hospital and in that context focus on research activities was increased. This article investigates whether the increased focus has led to changes in the quantity and/or quality of research publications in the following period. All scientific articles published by Aalborg Hospital in the period 2002-2008, as well as information about author affiliations comprise the data material for the analysis. Different levels of journal groups are created based on Journal Performance Indicators combined with peer-reviewing as a measure of publication quality, awarding publications in highly esteemed journals a higher score than those published in less recognized journals. Together with the number of publications, a measure of research quality and quantity is thereby achieved. This method is compared to the more traditional journal impact factor method. Data show an increase in total publications per year while the mean number of points per publication decreases during the period. Results also show a relation between the score level of publications and the number of collaborations for the publication, i.e. large collaborations are more frequently published in top journals. The study shows that the increased focus on research has led to increased publication activity without loss of quality, as the decrease in points per publication is associated with the increased mean number of collaborators. The results indicate that the method would benefit from a revision to facilitate clearer conclusions.

Physical Activity and Alzheimer's Disease: A Systematic Review.

PubMed

Stephen, Ruth; Hongisto, Kristiina; Solomon, Alina; Lönnroos, Eija

2017-06-01

The current literature includes several studies investigating the association between physical activity and risk of Alzheimer's disease (AD). The aim of this review was to systematically evaluate available evidence on this association. Medline via PubMed and CINAHL databases were searched for original English language research articles assessing the relationship between physical activity and incident AD. The review was limited to prospective observational and intervention studies. Criteria for exclusion were studies focusing on individuals with dementia, cross-sectional study design, and case reports. The quality of included studies was assessed in 5 domains of bias. Twenty-four studies met the inclusion criteria. The number of participants ranged from 176 to 5,698. Follow-up time varied from 1 to 34 years. Physical activity was inversely associated with risk of AD in most studies (n = 18). Leisure-time physical activity was particularly protective against AD, but not work-related physical activity. The risk of bias assessment showed that overall quality of evidence was moderate for 16 and low for 8 studies. Beyond all the available general recommendations for health promotion, current evidence does not allow to draw specific practical recommendations concerning the types, frequency, intensity, or duration of physical activity that may be protective against AD. © The Author 2017.

to analyze scientific output from Spanish hospitals in relation to Helicobacter pylori infection. papers collected from the Medline database between January 1988 and December 2003 were selected. Our search strategy was: "Helicobacter pylori" [MeSH] AND ((Spain [AD] OR Espana [AD] OR Spanien [AD] OR Espagne [AD] OR Espanha [AD]) OR (Spanish [LA]) OR Spain). The following was analyzed: geographic area, Spanish or foreign publication, topic, and year of publication. Output and impact bibliometric markers were evaluated. in all, 691 papers were identified, of which 241 were excluded. Number of papers went from 2 in 1988 to 47 in 2002 and 13 in 2003. There were more reports in Spanish versus foreign journals (58 vs. 42%). In the first 5 years the areas with greater output were associated with diagnosis and microbiology (33 and 20%), whereas therapy was the predominating subject during the last 5 years (27%). Original papers were most common among publications (69%). Hospitals with highest output included La Princesa (24%) and Ramón y Cajal (17.6%) in Madrid, and Parc Taulí in Barcelona (6.4%). Mean impact factor progressively increased from 1.826 in 1988 to 2.142 in 2002 and 2.493 in 2003. the production and impact of documents published by Spanish scientists regarding H. pylori infection considerably increased during the past two decades.

The Roots of Alzheimer's Disease: Are High-Expanding Cortical Areas Preferentially Targeted?†.

Alzheimer's disease (AD) is regarded a human-specific condition, and it has been suggested that brain regions highly expanded in humans compared with other primates are selectively targeted. We calculated shared and unique variance in the distribution of AD atrophy accounted for by cortical expansion between macaque and human, affiliation to the default mode network (DMN), ontogenetic development and normal aging. Cortical expansion was moderately related to atrophy, but a critical discrepancy was seen in the medial temporo-parietal episodic memory network. Identification of "hotspots" and "coldspots" of expansion across several primate species did not yield compelling evidence for the hypothesis that highly expanded regions are specifically targeted. Controlling for distribution of atrophy in aging substantially attenuated the expansion-AD relationship. A path model showed that all variables explained unique variance in AD atrophy but were generally mediated through aging. This supports a systems-vulnerability model, where critical networks are subject to various negative impacts, aging in particular, rather than being selectively targeted in AD. An alternative approach is suggested, focused on the interplay of the phylogenetically old and preserved medial temporal lobe areas with more highly expanded association cortices governed by different principles of plasticity and stability. © The Author 2014.

Impact factor and other indices to assess science, scientists and scientific journals.

PubMed

Satyanarayana, K

2010-01-01

This paper traces the evolution of measures and parameters for the evaluation of science and scientific journals from the first attempts during the early part of the last century to the development of the most popular, current and widely used metrics viz., citations, impact factor (IF) etc. The identification of measures of evaluation in science and scientific reporting paralled the post-war increase in funding in the United States of America. Biomedical and medical sciences continue to garner a major share, estimated to be almost two-thirds of total research and development funding of over US$ 350 billion. There has been a concomitant growth in the publications in learned journals. About 1.4 million papers are published every year in an estimated 20,000 journals. In India there are an estimated 100 journals in medical sciences. With a steady increase of about 10% every year, the competition for grants, awards, rewards etc., is fierce. This unrelenting increase in number of scientists and the resultant competition, the limitation of peer review was felt. A search was on for new quantifiable measures for informed decision making for funding, awards, rewards, etc. Now virtually all major decisions all over the world are based on some data linked to publications and/or citations. The concept of citations as tool for 'evaluating' science was first proposed by Eugene Garfield in 1955. The availability of Science Citation Index (SCI), Journal Citation Reports (JCR), Web of Science etc. and the relative ease with which they could be used (and abused) has spawned an entirely new area bibliometrics/scientometrics. As only a limited number of journals could be included in the Thomson Reuters (TR) databases (currently numbering about 10500), analyses based on such a limited dataset (also selected in a non-transparent way by the TR) has been widely and severely criticized by both the developed and developing countries. Yet, studies have shown that citation-based data and indicators (warts and all) could still be put to productive use for purposes of evaluation (as scientists just love numbers). There were simultaneous efforts to find alternative indicators using the TR databases, and through other innovative methods. Some of these include Google Scholar, PageRank, H-index, Y-factor, Faculty of 1000, Eigen Factor etc. The advantages and limitations of these indices are discussed. There is a need for a more critical look at these parameters from the Indian perspective to compute/ device/adapt these measures to suit our needs. There are 205 journals under the category Physiology and 201 in the Pharmacology category listed in the JCR. There are four major Indian journals under the category of Physiology and Pharmacology and none of them are listed in the TR databases reflecting the limitation of these databases. Eventually, and in the long run, the quality of our journals needs to be improved as the current era of globalization and web-access provides both a challenge and an oppportunity for the science and scientific journals published from India to get increased global visibility.

Tree-ring-width-based PDSI reconstruction for central Inner Mongolia, China over the past 333 years

A tree-ring-width chronology was developed from Pinus tabulaeformis aged up to 333 years from central Inner Mongolia, China. The chronology was significantly correlated with the local Palmer Drought Severity Index (PDSI). We therefore reconstructed the first PDSI reconstruction from March to June based on the local tree ring data from 1680 to 2012 AD. The reconstruction explained 40.7 % of the variance (39.7 % after adjusted the degrees of freedom) of the actual PDSI during the calibration period (1951-2012 AD). The reconstructed PDSI series captured the severe drought event of the late 1920s, which occurred extensively in northern China. Running variance analyses indicated that the variability of drought increased sharply after 1960, indicating more drought years, which may imply anthropogenic related global warming effects in the region. In the entire reconstruction, there were five dry periods: 1730-1814 AD, 1849-1869 AD, 1886-1942 AD (including severe drought in late 1920s), 1963-1978 AD and 2004-2007 AD; and five wet periods: 1685-1729 AD, 1815-1848 AD, 1870-1885 AD, 1943-1962 AD and 1979-2003 AD. Conditions turned dry after 2003 AD, and the PDSI from March to June (PDSI36) captured many interannual extreme drought events since then, such as 2005-2008 AD. The reconstruction is comparable to other tree-ring-width-based PDSI series from the neighboring regions, indicating that our reconstruction has good regional representativeness. Significant relationships were found between our PDSI reconstruction and the solar radiation cycle and the sun spot cycle, North Atlantic Oscillation, the El Niño-Southern Oscillation, as well as the Pacific Decadal Oscillation. Power spectral analyses detected 147.0-, 128.2-, 46.5-, 6.5-, 6.3-, 2.6-, 2.2- and 2.0-year quasi-cycles in the reconstructed series.

Mitochondria and Mitochondrial Cascades in Alzheimer’s Disease

PubMed Central

Swerdlow, Russell H.

2017-01-01

Decades of research indicate mitochondria from Alzheimer’s disease (AD) patients differ from those of non-AD individuals. Initial studies revealed structural differences, and subsequent studies showed functional deficits. Observations of structure and function changes prompted investigators to consider the consequences, significance, and causes of AD-related mitochondrial dysfunction. Currently, extensive research argues mitochondria may mediate, drive, or contribute to a variety of AD pathologies. The perceived significance of these mitochondrial changes continues to grow, and many currently believe AD mitochondrial dysfunction represents a reasonable therapeutic target. Debate continues over the origin of AD mitochondrial changes. Some argue amyloid-β (Aβ) induces AD mitochondrial dysfunction, a view that does not challenge the amyloid cascade hypothesis and that may in fact help explain that hypothesis. Alternatively, data indicate mitochondrial dysfunction exists independent of Aβ, potentially lies upstream of Aβ deposition, and suggest a primary mitochondrial cascade hypothesis that assumes mitochondrial pathology hierarchically supersedes Aβ pathology. Mitochondria, therefore, appear at least to mediate or possibly even initiate pathologic molecular cascades in AD. This review considers studies and data that inform this area of AD research.

Alzheimer's disease (AD) is an age-dependent neurodegenerative disease constituting ~95% of late-onset non-familial/sporadic AD, and only ~5% accounting for early-onset familial AD. Availability of a pertinent model representing sporadic AD is essential for testing candidate therapies. Emerging evidence indicates a causal link between diabetes and AD. People with diabetes are >1.5-fold more likely to develop AD. Senescence-accelerated mouse model (SAMP8) of accelerated aging displays many features occurring early in AD. Given the role played by diabetes in the pre-disposition of AD, and the utility of SAMP8 non-transgenic mouse model of accelerated aging, we examined if high fat diet-induced experimental type 2 diabetes in SAMP8 mice will trigger pathological aging of the brain. Results showed that compared to non-diabetic SAMP8 mice, diabetic SAMP8 mice exhibited increased cerebral amyloid-β, dysregulated tau-phosphorylating glycogen synthase kinase 3β, reduced synaptophysin immunoreactivity, and displayed memory deficits, indicating Alzheimer-like changes. High fat diet-induced type 2 diabetic SAMP8 mice may represent the metabolic model of AD.

Academic publishers claim that they add value to scholarly communications by coordinating reviews and contributing and enhancing text during publication. These contributions come at a considerable cost: US academic libraries paid $1.7 billion for serial subscriptions in 2008 alone. Library budgets, in contrast, are flat and not able to keep pace with serial price inflation. Here, we have investigated the publishers’ value proposition by conducting a comparative study of pre-print papers from two distinct science, technology, and medicine corpora and their final published counterparts. This comparison had two working assumptions: (1) If the publishers’ argument is valid, the text ofmore » a pre-print paper should vary measurably from its corresponding final published version, and (2) by applying standard similarity measures, we should be able to detect and quantify such differences. Our analysis revealed that the text contents of the scientific papers generally changed very little from their pre-print to final published versions. These findings contribute empirical indicators to discussions of the added value of commercial publishers and therefore should influence libraries’ economic decisions regarding access to scholarly publications.« less

The Most Distant X-Ray Clusters

Dickinson, Mark

1999-01-01

In this program we have used ROSAT (Roentgen Satellite Mission) to observe X-ray emission around several high redshift radio galaxies in a search for extended, hot plasma which may indicate the presence of a rich galaxy cluster. When this program was begun, massive, X-ray emitting galaxy clusters were known to exist out to to z=0.8, but no more distant examples had been identified. However, we had identified several apparently rich clusters around 3CR radio galaxies at z greater than 0.8, and hoped to use ROSAT to confirm the nature of these structures as massive, virialized clusters. We have written up our results and submitted them as a paper to the Astrophysical Journal. This paper has been refereed and requires some significant revisions to accommodate the referees comments. We are in the process of doing this, adding some additional analysis as well. We will resubmit the paper early in 2000, and hopefully will meet with the referee's approval. We are including three copies of the submitted paper here, although it has not yet been accepted for publication.

To make electronic resources available to library users while effectively harnessing intellectual capital within the library, ultimately fostering the library's use of technology to interact asynchronously with its patrons (users). The methods used in the project included: (1) developing a new library website to facilitate the creation, management, accessibility, maintenance and dissemination of library resources; and (2) establishing ownership by those who participated in the project, while creating effective work allocation strategies through the implementation of a content management system that allowed the library to manage cost, complexity and interoperability. Preliminary results indicate that contributors to the system benefit from an increased understanding of the library's resources and add content valuable to library patrons. These strategies have helped promote the manageable creation and maintenance of electronic content in accomplishing the library's goal of interacting with its patrons. Establishment of a contributive system for adding to the library's electronic resources and electronic content has been successful. Further work will look at improving asynchronous interaction, particularly highlighting accessibility of electronic content and resources. © 2010 The authors.

Adequate dose management during computed tomography is important. In the present study, the dosimetric application software ImPACT was added to a functional calculator of the size-specific dose estimate and was part of the scan settings for the auto exposure control (AEC) technique. This study aimed to assess the practicality and accuracy of the modified ImPACT software for dose estimation. We compared the conversion factors identified by the software with the values reported by the American Association of Physicists in Medicine Task Group 204, and we noted similar results. Moreover, doses were calculated with the AEC technique and a fixed-tube current of 200 mA for the chest-pelvis region. The modified ImPACT software could estimate each organ dose, which was based on the modulated tube current. The ability to perform beneficial modifications indicates the flexibility of the ImPACT software. The ImPACT software can be further modified for estimation of other doses. © The Author 2016.

Bibliometric Indicators of Russian Journals by JCR-Science Edition, 1995-2010.

Libkind, A N; Markusova, V A; Mindeli, L E

2013-07-01

A representative empirical bibliometric analysis of Russian journals included in the Journal Citation Reports-Science Edition (JCR-SE) for the time period 1995-2010 was conducted at the macro level (excluding the subject categories). It was found that the growth in the number of articles covered by JCR (a 1.8-fold increase compared to 1995) is ahead of the growth rates of Russian publications (1.2-fold increase). Hence, the share of Russian articles covered by JCR-SE was down from 2.5% in 1995 to 1.7% in 2010. It was determined that the number of articles published in an average Russian journal reduced by 20% as compared to the number of articles in an average journal of the full data set. These facts could partly shed light on the question why Russian research performance is staggering (approximately 30,000 articles per year), although the coverage of Russian journals has expanded to 150 titles. Over the past 15 years, a twofold increase in the impact factor of the Russian journals has been observed, which is higher than that for the full data set of journals (a 1.4-fold increase). Measures to improve the quality of Russian journals are proposed.

Mari JJ, Patel V, Kieling C, Razzouk D, Tyrer P, Herrman H. The 5/95 gap in the indexation of psychiatric journals of low- and middle-income countries. Objective: To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. Method: Indicators of productivity in research were based on the number of articles produced over the 1994–2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their country of origin. A WPA Task Force designed a collaborative process to assess distribution and quality of non-indexed LAMIC journals. Results: Twenty LAMIC were found to present more than 100 publications and a total of 222 indexed psychiatric journals were found, but only nine were from LAMIC. The Task Force received 26 questionnaires from editors of non-indexed journals, and concluded that five journals would meet criteria for indexation. Conclusion: Barriers to indexation of journals contribute to the difficulties in achieving fair representation in the main literature databases for the scientific production in these countries.

Using Multicountry Ecological and Observational Studies to Determine Dietary Risk Factors for Alzheimer's Disease.

PubMed

Grant, William B

2016-07-01

Rates of Alzheimer's disease (AD) are rising worldwide. The most important risk factors seem to be linked to diet. For example, when Japan made the nutrition transition from the traditional Japanese diet to the Western diet, AD rates rose from 1% in 1985 to 7% in 2008. Foods protective against AD include fruits, vegetables, grains, low-fat dairy products, legumes, and fish, whereas risk factors include meat, sweets, and high-fat dairy products. The evidence comes from ecological and observational studies as well as investigations of the mechanisms whereby dietary factors affect risk. The mechanisms linking dietary risk factors to AD are fairly well known and include increased oxidative stress from metal ions such as copper as well as from advanced glycation end products associated with high-temperature cooking, increased homocysteine concentrations, and cholesterol and its effects on amyloid beta, insulin resistance, and obesity. Lower 25-hydroxyvitamin D concentrations also are associated with increased risk of AD. In addition to reviewing the journal literature, a new ecological study was conducted using AD prevalence from 10 countries (Brazil, Chile, Cuba, Egypt, India, Mongolia, Nigeria, Republic of Korea, Sri Lanka, and the United States) along with dietary supply data 5, 10, and 15 years before the prevalence data. Dietary supply of meat or animal products less milk 5 years before AD prevalence had the highest correlations with AD prevalence in this study. Thus, reducing meat consumption could significantly reduce the risk of AD as well as of several cancers, diabetes mellitus type 2, stroke, and, likely, chronic kidney disease. • Single-country ecological data can be used to find links between diet and AD because the national diet changes, such as during the nutrition transition to a Western diet. • Multicountry ecological studies can be used to find links between dietary factors and risk of AD. • Prospective observational studies are useful in linking dietary components and patterns to risk of AD. • The most important dietary link to AD appears to be meat consumption, with eggs and high-fat dairy also contributing. • Diets high in grains, fruits, vegetables, and fish are associated with reduced risk of AD, but these factors cannot counter the effects of meat, eggs, and high-fat dairy. • Higher vitamin D status is associated with reduced risk of AD.

Open access versus subscription journals: a comparison of scientific impact

PubMed Central

2012-01-01

Background In the past few years there has been an ongoing debate as to whether the proliferation of open access (OA) publishing would damage the peer review system and put the quality of scientific journal publishing at risk. Our aim was to inform this debate by comparing the scientific impact of OA journals with subscription journals, controlling for journal age, the country of the publisher, discipline and (for OA publishers) their business model. Methods The 2-year impact factors (the average number of citations to the articles in a journal) were used as a proxy for scientific impact. The Directory of Open Access Journals (DOAJ) was used to identify OA journals as well as their business model. Journal age and discipline were obtained from the Ulrich's periodicals directory. Comparisons were performed on the journal level as well as on the article level where the results were weighted by the number of articles published in a journal. A total of 610 OA journals were compared with 7,609 subscription journals using Web of Science citation data while an overlapping set of 1,327 OA journals were compared with 11,124 subscription journals using Scopus data. Results Overall, average citation rates, both unweighted and weighted for the number of articles per journal, were about 30% higher for subscription journals. However, after controlling for discipline (medicine and health versus other), age of the journal (three time periods) and the location of the publisher (four largest publishing countries versus other countries) the differences largely disappeared in most subcategories except for journals that had been launched prior to 1996. OA journals that fund publishing with article processing charges (APCs) are on average cited more than other OA journals. In medicine and health, OA journals founded in the last 10 years are receiving about as many citations as subscription journals launched during the same period. Conclusions Our results indicate that OA journals indexed in Web of Science and/or Scopus are approaching the same scientific impact and quality as subscription journals, particularly in biomedicine and for journals funded by article processing charges.

To compare cued recall measures with other memory and nonmemory tests regarding their association with a biomarker profile indicative of Alzheimer disease (AD) in CSF among patients with mild cognitive impairment (MCI). Data were obtained by the German Dementia Competence Network. A total of 185 memory clinic patients fulfilling broad criteria for MCI (1 SD deficit in memory tests or in nonmemory tests) were assessed with an extended neuropsychological battery, which included the Free and Cued Selective Reminding Test (FCSRT), the word list learning task from the Consortium to Establish a Registry for Alzheimer's Disease neuropsychological battery (CERAD-NP), and the Logical Memory (LM) paragraph recall test from the Wechsler Memory Scale-Revised. CSF was obtained from all patients. A total of 74 out of 185 subjects with MCI (40%) had a CSF profile consistent with AD (Aβ(1-42)/tau ratio; CSF AD+ group). FCSRT measures reflecting both free and cued recall discriminated best between CSF AD+ and CSF AD- patients, and significantly improved CSF AD classification accuracy, as compared with CERAD delayed recall and LM delayed recall. Cued recall deficits are most closely associated with CSF biomarkers indicative of AD in subjects with MCI. This novel finding complements results from prospective clinical studies and provides further empirical support for cued recall as a specific indicator of prodromal AD, in line with recently proposed research criteria.

There is substantial in-vitro data indicating that curcumin has antioxidant, anti-inflammatory, and anti-amyloid activity. In addition, studies in animal models of Alzheimer’s disease (AD) indicate a direct effect of curcumin in decreasing the amyloid pathology of AD. As the widespread use of curcumin as a food additive and relatively small short-term studies in humans suggest safety, curcumin is a promising agent in the treatment and/or prevention of AD. Nonetheless, important information regarding curcumin bioavailability, safety and tolerability, particularly in an elderly population is lacking. We are therefore performing a study of curcumin in patients with AD to gather this information in addition to data on the effect of curcumin on biomarkers of AD pathology. PMID:15974909

Tree-ring growth patterns and climatic signals along a vertical transect of larch sites in the Simplon and Rhône Valleys (Switzerland)

State-of-the-art millennial long temperature reconstructions from the European Alps integrate wood samples of Larix decidua Mill. from the Lötschental and Simplon regions in Switzerland (Büntgen et al., 2005; 2006). Some of the oldest samples that enable the extension of the time-series back into the first millennium AD are obtained from old buildings in Simplon Village, through the precise location of these samples and the elevation of sampling sites remain unknown. We here evaluate the growth characteristics of larch tree-ring width data along a vertical transect in the Simplon and Rhône valleys. 330 trees from nine sites in 985, 1100, 1400, 1575, 1710, 1712, 1900, 2020, and 2150 m asl have been sampled and analysed for their climate signals. The results indicate a stronger temperature signal in the tree-ring width with increasing elevation. The lower the sites the more a drought signal is imprinted in the ring width data. The intermediate site at 1400 m asl does not show any pronounced climate signal. A comparison of growth patterns of living-tree sites with samples from the historical buildings in Simplon Village (Riechelmann et al., 2013) indicates the construction timber to origin from intermediate to higher elevations. We therefore do not expect strong temperature signal from these timbers. References: Büntgen, U., Esper, J., Frank, D.C., Nicolussi, K., Schmidhalter, M., 2005.

It is a useful synthesis of the vast and often obscure literature on the more than 100 species of shearwaters, petrels, albatrosses, and fulmars that comprise the avian order with the widest range of body mass (19.5 g to 8.7 kg) and widest distribution, throughout the world's oceans, from the tropics to open leads in polar ice packs. The order's literary credentials are also impressive, with contributions from Dionysus (200 AD), St. Augustine, and Cole- ridge (not cited). Warham has also unearthed useful references from journals not examined by many ornithologists, such as Bocagiana, Il-Merill, and the Journal of the Manx Museum. He also appears to have done a good job of covering the Japanese-language literature.

40 years of veterinary papers in JAC - what have we learnt?

This review, for the occasion of the 40th anniversary of the Journal of Antimicrobial Chemotherapy (JAC), gives an overview of the manuscripts related to veterinary bacteriology published in the journal in the past 40 years with a focus on 'One Health' aspects. From 1975 to 2000 the number of manuscripts related to veterinary medicine was limited, but thereafter, the number steadily increased. Most manuscripts published were related to food-producing animals, but companion animals and minor species were also covered. Subjects included antimicrobial usage in animals and the consequences for human medicine, new resistance genes and mechanisms, the prevalence and epidemiology of antimicrobial resistance, and the emergence of resistant bacteria in animals with zoonotic potential such as livestock-associated MRSA (LA-MRSA), methicillin-resistant Staphylococcus pseudintermedius (MRSP) and ESBL-producing Enterobacteriaceae. These manuscripts have added to our knowledge on the risks of transmission of resistant bacteria from animals to humans and the importance of the prudent use of antimicrobial agents in veterinary medicine. © The Author 2016.

[On-line journals--are they the future? ].

Geges, József; Vasas, Lívia

2007-01-21

The significant growth of the online literature usage, and the conspicuously differing interest of publishers, procurers and users raise the question whether the electronic or the paper journals will be the primary information sources in the future. The price of the scientific literature has gotten out of control in the last two decades. At the same time websites showed up providing open access, and this may make all participants of the market to change their marketing policy. Instead of the extra-profit accumulation strategy, publishers should take individual users' interests into consideration. Although the technical conditions of value-added option-enriched online services to surpass the paper journals are given already, there is still a demand for the latter, due to ingrained user habits. At the same time, the electronic version is attracting the users with e-versions, three-dimensional images, video records, sound, hypertext, content and relation analysis, which are limited only by the imagination. According to the authors, the development of information media is unstoppable, and the main challenge in the future will be still to find the most effective way of processing information, make it available for professional research and preserve it for the scientific heritage.

Women and the media in Malaysia.

PubMed

Adnan, M H

1987-01-01

The contributions of and portrayal of women in the Malaysian media are summarized here in detail. Women's access to training in journalism and education is on average better than that of men. There are 3 communications departments in institutions of higher learning in Malaysia, and all enroll more women than men, probably because of women's better language skills and desire to enter a "glamourous" profession. Women's participation in journalism, except for women's magazines, is much more limited, especially at higher levels. Women's abilities are not lacking, as shown by the number of awards Malaysian women journalists have won, but it is felt that women are not assertive, cannot work late or night shifts, cannot be transferred, because of family and domestic obligations. Perhaps journalism curricula should offer women extra courses in effective family management, public speaking or human relations, or assign cadet journalists women mentors. In Malaysia women are generally portrayed in print, electronic and advertising media as either decorative, foolish, consumption driven, or sex objects. Exploitative poses predominate in ads for male markets, such as automobiles and liquor. Sexual roles for women and girls are depicted as those of subservient or silly housewife or in other negative or traditional roles.

A review of sugar consumption from nationally representative dietary surveys across the world.

PubMed

Newens, K J; Walton, J

2016-04-01

Government and health organisations worldwide have recently reviewed the evidence on the role of dietary sugars in relation to health outcomes. Hence, it is timely to review current intakes of dietary sugars with respect to this guidance and as a benchmark for future surveillance. This review collates data from nationally representative dietary surveys across the world and reports estimates of intakes of total and added sugars, and sucrose in different population subgroups. Total sugars includes all mono- and disaccharides; namely, glucose, fructose, lactose, sucrose and maltose. Added and free sugars differ in the quantity of natural sugars included in their definitions. Free sugars include sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates, whereas added sugars typically only refer to those added during processing. Most countries reported intakes of total sugars, with fewer reporting intakes of added sugars and sucrose. No country reported intakes of free sugars. The available data suggest that total sugars as a percentage of energy were highest in the infant (<4 years), with mean values ranging from 20.0% to 38.4%, and decreased over the lifespan to 13.5-24.6% in adults. Intakes of added sugars were higher in school-aged children and adolescents (up to 19% of total energy) compared to younger children or adults. Further research into the dietary patterns contributing to added sugars intake in children and adolescents is warranted. It would also be beneficial to policy guidance if future dietary surveys employed a uniform way of expressing sugars that is feasible to measure and has public health significance. © 2015 The Authors.

Halpin, Sean N; Dillard, Rebecca L; Puentes, William J

2017-08-01

The emotional reactions to the progression of Mild Cognitive Impairment and Alzheimer's disease (MCI/AD) oftentimes present as cognitive or behavioral changes, leading to misguided interventions by Formal Support (paid health care providers). Despite a rich body of literature identifying cognitive and behavioral staging of MCI/AD, the emotional changes that accompany these diagnoses have been largely ignored. The objective of this study was to develop a model of the emotional aspects of MCI/AD. One hour, semistructured interviews, with 14 patient-Informal Support Partner dyads (N = 28) interviewed concurrently; patients were in various stages of MCI/AD. An interdisciplinary team employed a grounded theory coding process to detect emotional characteristics of the participants with MCI/AD. Emotional reactions were categorized into depression/sadness, apathy, concern/fear, anger/frustration, and acceptance. The emotions did not present linearly along the course of the disease and were instead entwined within a set of complex (positive/negative) interactions including: relationship with the Informal Support Partner (i.e., teamwork vs infantilization), relationship with the Formal Support (i.e., patient vs disengaged), coping (i.e., adaptive vs nonadaptive), and perceived control (i.e., internal vs external locus-of-control). For example, a person with poor formal and informal support and external locus-of-control may become depressed, a condition that is known to negatively affect cognitive status. Understanding the emotional reactions of individuals diagnosed with MCI/AD will provide clinicians with information needed to develop treatments suited to current needs of the patient and provide Informal Support Partners insight into cognitive and physical changes associated with MCI/AD. © The Author 2016.

Global warming significantly affects Arctic tundra, including permafrost thaw and soluble C release that may differentially affect tundra microbial growth. Using laboratory experiments, we report some of the first evidence for the effects of soluble glucose-C enrichment on tundra soil prokaryotes (bacteria and archaea) and fungi, with comparisons to microbial eukaryotes. Fungal increase in C-biomass was equivalent to 10% (w/w) of the added glucose-C, and for prokaryote biomass 2% (w/w), the latter comparable to prior published results. The C-gain after 14 d was 1.3 mg/g soil for fungi, and ~200 μg/g for prokaryotes. © 2015 The Author(s) Journal of Eukaryotic Microbiology © 2015 International Society of Protistologists.

Comparison of indexing times among articles from medical, nursing, and pharmacy journals.

Rodriguez, Ryan W

2016-04-15

Results of an analysis of the times to indexing of articles published in medical, nursing, and pharmacy journals are reported. MEDLINE data were retrieved for articles published in selected general practice medical, nursing, and pharmacy journals and entered into the PubMed system in 2012 and 2013. Collected data included PubMed entry date, date of indexing with Medical Subject Headings (MeSH) terms, and publication characteristics. Survival analysis was performed to assess the primary outcome of time to indexing. Cox proportional hazards models were developed to assess the effect of healthcare discipline and source journal on the primary outcome. Data were collected for 19,259 articles, of which 78.7%, 12.6%, and 8.7% originated from medical, nursing, and pharmacy journals, respectively. For medical, pharmacy, and nursing journals, 97.8%, 90.8%, and 50.1% of articles, respectively, were indexed within one year of PubMed entry; the corresponding median (interquartile range) times to indexing were 52 (20-68), 186 (150-246), and 252 (168-301) days. Unadjusted hazard ratios derived from Cox models indicated that indexing within one year was significantly less likely for articles published in pharmacy or nursing journals versus medical journals and for articles from all evaluated journals versus a designated reference publication (New England Journal of Medicine). Analysis of major medical, nursing, and pharmacy journals found that articles from nursing and pharmacy journals were indexed with MeSH terms more slowly than articles from medical journals. Journal identity was significantly associated with time to indexing. Copyright © 2016 by the American Society of Health-System Pharmacists, Inc. All rights reserved.

Evaluating the MEDLINE Core Clinical Journals filter: data-driven evidence assessing clinical utility.

MEDLINE offers the Core Clinical Journals filter to limit to clinically useful journals. To determine its effectiveness for searching and patient-centric decision making, this study compared literature used for Morning Report in Internal Medicine with journals in the filter. An EndNote library with references answering 327 patient-related questions during Morning Report from 2007 to 2012 was exported to a file listing variables including designated Core Clinical Journal, Impact Factor, date used and medical subject. Bradford's law of scattering was applied ranking the journals and reflecting their clinical utility. Recall (sensitivity) and precision of the Core Morning Report journals and non-Core set was calculated. This study applied bibliometrics to compare the 628 articles used against these criteria to determine journals impacting decision making. Analysis shows 30% of clinically used articles are from the Core Clinical Journals filter and 16% of the journals represented are Core titles. When Bradford-ranked, 55% of the top 20 journals are Core. Articles <5 years old furnish 63% of sources used. Among the 63 Morning Report subjects, 55 have <50% precision and 41 have <50% recall including 37 subjects with 0% precision and 0% recall. Low usage of publications within the Core Clinical Journals filter indicates less relevance for hospital-based care. The divergence from high-impact medicine titles suggests clinically valuable journals differ from academically important titles. With few subjects demonstrating high recall or precision, the MEDLINE Core Clinical Journals filter may require a review and update to better align with current clinical needs. © 2014 John Wiley & Sons, Ltd.

Huchra, John

Just in the last few years scientific publishing has moved rapidly away from the modes that served it well for over two centuries. As "digital natives" take over the field and rapid and open access comes to dominate the way we communicate, both scholarly journals and libraries need to adopt new business models to serve their communities. This is best done by identifying new "added value" such as databases, full text searching, full cross indexing while at the same time retaining the high quality of peer reviewed publication.

Independent effects of adding weight and inertia on balance during quiet standing

PubMed Central

2012-01-01

Background Human balance during quiet standing is influenced by adding mass to the body with a backpack, with symmetrically-applied loads to the trunk, or with obesity. Adding mass to the body increases both the weight and inertia of the body, which theoretically could provide counteracting effects on body dynamics and balance. Understanding the independent effects of adding weight and inertia on balance may provide additional insight into human balance that could lead to novel advancements in balance training and rehabilitation. Therefore, the purpose of this study was to investigate the independent effects of adding weight and inertia on balance during quiet standing. Methods Sixteen normal-weight young adult participants stood as still as possible on a custom-built backboard apparatus under four experimental conditions: baseline, added inertia only, added weight only, and added inertia and weight. Results Adding inertia by itself had no measurable effect on center of pressure movement or backboard movement. Adding weight by itself increased center of pressure movement (indicated greater effort by the postural control system to stand as still as possible) and backboard movement (indicating a poorer ability of the body to stand as still as possible). Adding inertia and weight at the same time increased center of pressure movement but did not increase backboard movement compared to the baseline condition. Conclusions Adding inertia and adding weight had different effects on balance. Adding inertia by itself had no effect on balance. Adding weight by itself had a negative effect on balance. When adding inertia and weight at the same time, the added inertia appeared to lessen (but did not eliminate) the negative effect of adding weight on balance. These results improve our fundamental understanding of how added mass influences human balance. PMID:22507125

The aim of this study was to compare the psychometric properties of the "Word" and "Picture" versions of the Spanish FCSRT across the same sample of mild Alzheimer disease (AD) patients and controls. Mild AD patients (N = 50, 27 CDR = 0.5; 23 CDR = 1) and controls (N = 42, CDR = 0) were assessed with an extensive clinical and neuropsychological evaluation. Psychometric characteristics for both versions of the FCSRT were compared. Free recall (FR) and total recall (TR) across both versions of the FCSRT showed areas under the curve >0.9 and did not significantly differ between them. The scores of both versions were well correlated, although the scores for the Picture version were greater than those for the Word version, particularly for the TR scores of the mild AD group. Both versions of the FCSRT showed an appropriate accuracy to distinguish mild AD patients and controls. Visual cues were easier to recall than verbal cues, especially in the memory impaired patients. © The Author 2016. Published by Oxford University Press. All rights reserved.

The article service of the Astrophysics Data System (ADS, http://adswww.harvard.edu) currently holds about 500,000 pages scanned from astronomical journals and conference proceedings. This data set not only facilitates an easy and convenient access to the majority of the astronomical literature from anywhere on the Internet but also allows highly automatized extraction of the information contained in the articles. As first steps towards processing and indexing the full texts of the articles, the ADS has been extracting abstracts and references from the bitmap images of the articles since May 1999. In this poster we describe the procedures and strategies to (a) automatically identify the regions within a paper containing the abstract or the references, (b) spot and correct errors in the data base or the identification of the regions, (c) resolve references obtained by optical character recognition (OCR) with its inherent uncertainties to parsed references (i.e., bibcodes) and (d) incorporate the data collected in this way into the ADS abstract service. We also give an overview of the extent of additional bibliographical material from this source. We estimate that by January 2000, these procedures will have yielded about 14,000 abstracts and 1,000,000 citation pairs (out of a total of 3,000,000 references) not previously present in the ADS.

From Nose to Memory: The Involuntary Nature of Odor-evoked Autobiographical Memories in Alzheimer's Disease.

Research suggests that odors may serve as a potent cue for autobiographical retrieval. We tested this hypothesis in Alzheimer's disease (AD) and investigated whether odor-evoked autobiographical memory is an involuntary process that shares similarities with music-evoked autobiographical memory. Participants with mild AD and controls were asked to retrieve 2 personal memories after odor exposure, after music exposure, and in an odor-and music-free condition. AD participants showed better specificity, emotional experience, mental time travel, and retrieval time after odor and music exposure than in the control condition. Similar beneficial effects of odor and music exposure were observed for autobiographical characteristics (i.e., specificity, emotional experience, and mental time travel), except for retrieval time which was more improved after odor than after music exposure. Interestingly, regression analyses suggested executive involvement in memories evoked in the control condition but not in those evoked after music or odor exposure. These findings suggest the involuntary nature of odor-evoked autobiographical memory in AD. They also suggest that olfactory cuing could serve as a useful and ecologically valid tool to stimulate autobiographical memory, at least in the mild stage of the disease. © The Author(s) 2017.

Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia. The Quality of Life in Alzheimer's Disease (QOL-AD) is a widely used and well-validated condition-specific instrument for assessing health-related quality of life for people living with dementia, but it does not enable the calculation of quality-adjusted life years, the basis of cost utility analysis. This study will generate a preference-based scoring algorithm for a health state classification system -the Alzheimer's Disease Five Dimensions (AD-5D) derived from the QOL-AD. Discrete choice experiments with duration (DCE TTO ) and best-worst scaling health state valuation tasks will be administered to a representative sample of 2000 members of the Australian general population via an online survey and to 250 dementia dyads (250 people with dementia and their carers) via face-to-face interview. A multinomial (conditional) logistic framework will be used to analyse responses and produce the utility algorithm for the AD-5D. The algorithms developed will enable prospective and retrospective economic evaluation of any treatment or intervention targeting people with dementia where the QOL-AD has been administered and will be available online. Results will be disseminated through journals that publish health economics articles and through professional conferences.

Atopic dermatitis, atopic eczema, or eczema? A systematic review, meta-analysis, and recommendation for uniform use of ‘atopic dermatitis’

PubMed Central

Kantor, R.; Thyssen, J. P.; Paller, A. S.; Silverberg, J. I.

2017-01-01

Background The lack of standardized nomenclature for atopic dermatitis (AD) creates unnecessary confusion for patients, healthcare providers, and researchers. It also negatively impacts accurate communication of research in the scientific literature. We sought to determine the most commonly used terms for AD. Methods A systematic review of the MEDLINE, EMBASE, and LILACS (1945–2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders. Results In MEDLINE, 33 060 were identified, of which 21 299 (64.4%) publications used the term ‘AD’, 15 510 (46.9%) ‘eczema’, and only 2471 (7.5%) AE. Most of these publications used the term AD (82.0%) or eczema (70.8%) without additional nomenclature; only 1.2% used AE alone. Few publications used the terminology ‘childhood eczema’, ‘flexural eczema’, ‘infantile eczema’, ‘atopic neurodermatitis’, or ‘Besnier’s prurigo’. AD was rarely used until the late 1970s, after which it became the most commonly used of the three terms and continuously increased until 2015. Atopic eczema decreased between 2008 and 2015. Atopic dermatitis was the most commonly used term in studies across almost all publication types, languages, and journals. Conclusion Atopic dermatitis is the most commonly used term and appears to be increasing in popularity. Given that eczema is a nonspecific term that describes the morphological appearance of several forms of dermatitis, we strongly suggest the use of a more specific term, AD, in publications, healthcare clinician training, and patient education. Support from researchers, reviewers, and editors is key to success. PMID:27392131

Prescription drug advertising: trends and implications.

PubMed

Krupka, L R; Vener, A M

1985-01-01

Prescription drug advertisements which appeared in two leading American medical journals in 1972, 1977 and 1982 were analyzed to discover possible trends in advertising. The 5016 ads examined showed that ads for the diuretic-cardiovasculars, especially the beta-adrenergic blocking agents and the slow channel inhibitors, as well as the analgesics, had increased, while ads for the anti-infectives and tranquilizers had diminished. The average amount of space allocated for each ad had increased. On the average, most ads (69%) depicted neither male nor female patients in their graphics, and a trend of increased neutrality was observed. When the hormones were excluded, an average of 21% of the ads showed male patients and 10% showed females. Since a relationship was discerned between the leading drugs advertised and the leading prescriptions filled, it was concluded that advertising does have some effect on the prescribing behavior of practitioners. The findings suggest that great investment in advertising is necessary in order to achieve high levels of sales for such drugs as Valium (diazepam) which do not have a clear-cut ameliorative effect on a specific physiological condition. On the other hand, it was suggested that saturation advertising would not significantly enhance the sales of such drugs as Dyazide (triamterene and hydrochlorothiazide) because of its well established therapeutic value in the control of hypertension. Ten advertising companies, on the average, had purchased 67% of all advertising space and five had purchased almost half (47%). The same two pharmaceutical companies were among the top five advertisers and the same five were among the top ten for the three years studied.

Human Atopic Dermatitis Skin-derived T Cells can Induce a Reaction in Mouse Keratinocytes in vivo.

In atopic dermatitis (AD), the inflammatory response between skin-infiltrating T cells and keratinocytes is fundamental to the development of chronic lesional eczema. The aim of this study was to investigate whether skin-derived T cells from AD patients could induce an inflammatory response in mice through keratinocyte activation and consequently cause the development of eczematous lesions. Punch biopsies of the lesional skin from AD patients were used to establish skin-derived T cell cultures, which were transferred to NOD.Cg-Prkd(scid) Il2rg(tm1Sug) /JicTac (NOG) mice. We found that the subcutaneous injection of the human AD skin-derived T cells resulted in the migration of the human T cells from subcutis to the papillary dermis followed by the development of erythema and oedema in the mouse skin. Furthermore, the human T cells induced a transient proliferative response in the mouse keratinocytes shown as increased numbers of Ki-67(+) keratinocytes and increased epidermal thickness. Out of six established AD skin-derived T cell cultures, two were superior at inducing a skin reaction in the mice, and these cultures were found to contain >10% CCR10(+) T cells compared to <2% for the other cultures. In comparison, blood-derived in vitro-differentiated Th2 cells only induced a weak response in a few of the mice. Thus, we conclude that human AD skin-derived T cells can induce a reaction in the mouse skin through the induction of a proliferative response in the mouse keratinocytes. © 2015 The Foundation for the Scandinavian Journal of Immunology.

It is well established that children are exposed to food marketing promoting calorically dense, low-nutrient products. Reducing exposure to obesogenic marketing presents an opportunity to improve children's health. The purpose of this study was to determine the extent to which televised food advertising practices targeting children (aged ≤12 years) were consistent with guidelines proposed by a coalition of federal authorities known as the Interagency Working Group on Foods Marketed to Children (IWG). A sample of children's TV programming aired on five national broadcast networks and two cable channels (N=103 shows) was recorded February to April 2013. The sample contained 354 food ads. Advertised products were identified and categorized using industry classification codes and nutrient data obtained from manufacturers. Product compliance with IWG saturated fat, trans fat, added sugar, and sodium guidelines was evaluated. Analyses conducted in 2013 revealed that nearly all food ads (94%) met guidelines for trans fats; 68% and 62% met guidelines for sodium and saturated fat, respectively; and 20% complied with added sugar guidelines. Overall, 1.4% of all child-targeted food ads met all aspects of IWG guidelines. Nearly all food advertisements exceeded guidelines for at least one recommended nutrient to limit. Individually, conformity was high for guidelines for trans fats, moderate for sodium and saturated fats, and poor for added sugar. These findings suggest that child-targeted food advertising remains strongly biased toward less healthy options. Policymakers wishing to regulate food marketing should understand the amount and types of advertisements that children view. Copyright © 2015 American Journal of Preventive Medicine.

Neurotrophins, including nerve-growth factor and brain-derived neurotrophic factor, have been implicated in Alzheimer's disease (AD). Associations between AD and neurotrophin signaling genes have been inconsistent, with few studies examining sex differences in risk. We examined four single-nucleotide polymorphisms (SNPs) involved in neurotrophin signaling (rs6265, rs56164415, rs2289656, rs2072446) and risk for AD by sex in a population-based sample of older adults. Three thousand four hundred and ninety-nine individuals without dementia at baseline [mean (standard deviation) age = 74.64 (6.84), 58% female] underwent dementia screening and assessment over four triennial waves. Cox regression was used to examine time to AD or right censoring for each SNP. Female carriers of the minor T allele for rs2072446 and rs56164415 had a 60% (hazard ratio [HR] = 1.60, 95% confidence interval [CI] = 1.02-2.51) and 93% (HR = 1.93, 95% CI = 1.30-2.84) higher hazard for AD, respectively, than male noncarriers of the T allele. Furthermore, male carriers of the T allele of rs2072446 had a 61% lower hazard (HR = 0.39, 95% CI = 0.14-1.06) than male noncarriers at trend-level significance (p = .07). The association between certain neurotrophin gene polymorphisms and AD differs by sex and may explain inconsistent findings in the literature. © The Author 2017.

[International visibility and impact of the Spanish research on prison health (2002-2011)].

PubMed

Ruíz-Pérez, R; Robinson-García, N

2013-01-01

This paper sets out to analyze the dissemination and impact of Spanish research published in international scientific journals on Prison Health over the last decade. Descriptive, longitudinal and retrospective analysis of scientific output. We used the Medline-Pubmed database as an information resource. We focus on the bibliometric aspects of journals, papers and authors using the indicators offered by the Web of Science, the Journal Citation Reports and the Essential Science Indicators. We identify the output of Spanish researchers, journals in which they are published, authors and main research fields. From 2002 to 2011, Spanish researchers published 159 papers, that is, nearly 2% of the world's share in Prison Health. The publication profile is mainly in international journals with an average impact on JCR. The Revista Española de Sanidad Penitenciaria is the most productive journal (9.09%), although its role is not prominent. Only two authors can be considered as medium-high productive authors with 10 papers in the study time period. The co-authors network shows a dense network with 14 authors along with minor fragmented networks. As regards citations, 6 papers have been cited 15 or more times and only two can be considered as highly cited. Three main research fronts have been identified: infectious diseases, drugs and psychiatric-psychological problems. The Spanish research production on Prison Health represents a similar share of the world output similar to that of other disciplines (1.9%), although slightly lower (General Medicine represents 3.05%; Public Health, 2.38%; Psychiatry, 2.29%; Toxicology, 2.46%). It seems likely that this share will increase as a result of the inclusion of its main journal in Medline along with an increasing number of researchers working on this discipline at an international level. However, inclusion has not yet led to integration into high-impact journals or a larger number of citations. The average Journal Impact Factor is relatively low (2.062) and few papers are published in first-class journals (Q1). There are few articles with a good citation average according to the discipline's standard. Likewise, the collaboration pattern still shows a poor state for Spanish research on Prison Health.

How to Rank Journals

PubMed Central

Bradshaw, Corey J. A.; Brook, Barry W.

2016-01-01

There are now many methods available to assess the relative citation performance of peer-reviewed journals. Regardless of their individual faults and advantages, citation-based metrics are used by researchers to maximize the citation potential of their articles, and by employers to rank academic track records. The absolute value of any particular index is arguably meaningless unless compared to other journals, and different metrics result in divergent rankings. To provide a simple yet more objective way to rank journals within and among disciplines, we developed a κ-resampled composite journal rank incorporating five popular citation indices: Impact Factor, Immediacy Index, Source-Normalized Impact Per Paper, SCImago Journal Rank and Google 5-year h-index; this approach provides an index of relative rank uncertainty. We applied the approach to six sample sets of scientific journals from Ecology (n = 100 journals), Medicine (n = 100), Multidisciplinary (n = 50); Ecology + Multidisciplinary (n = 25), Obstetrics & Gynaecology (n = 25) and Marine Biology & Fisheries (n = 25). We then cross-compared the κ-resampled ranking for the Ecology + Multidisciplinary journal set to the results of a survey of 188 publishing ecologists who were asked to rank the same journals, and found a 0.68–0.84 Spearman’s ρ correlation between the two rankings datasets. Our composite index approach therefore approximates relative journal reputation, at least for that discipline. Agglomerative and divisive clustering and multi-dimensional scaling techniques applied to the Ecology + Multidisciplinary journal set identified specific clusters of similarly ranked journals, with only Nature & Science separating out from the others. When comparing a selection of journals within or among disciplines, we recommend collecting multiple citation-based metrics for a sample of relevant and realistic journals to calculate the composite rankings and their relative uncertainty windows.

Publication Metrics of Dental Journals - What is the Role of Self Citations in Determining the Impact Factor of Journals?

PubMed

Elangovan, Satheesh; Allareddy, Veerasathpurush

2015-09-01

The objectives of the present study are to examine the publication metrics of dental journals and to delineate the role of self citations in determining the impact factor of journals. The Journal Citation Reports database was used. All dental journals that had an impact factor assigned for year 2013 were selected. The outcomes were Impact Factor (IF), Eigenfactor™ (EF), article influence score (AIS), and proportion of self-citations to total citations. Independent variables were geographic region of journal and ranking of journal (based on IF). Non-parametric tests were used to examine the associations between outcomes and independent variables. During the year 2013, 82 journals in dentistry had an IF. Mean IF was 1.489 and mean IF without including self-citations was 1.231. Mean EF scores and AIS were .00458 and .5141 respectively. Mean percentage of self cites to total citations for all dental journals was 12.24%. Higher ranking journals were associated with significantly higher EF and AIS. Journals published in USA/Canada or Europe were associated with higher IF and EF compared to those published in other regions. There were no differences in percentages of self citations to total citations either across journal rankings or geographic region. Top ranking journals tend to have higher IFs due to higher EF and AIS rather than by self-citations. Self-citations increase the impact factors of dental journals by 21%. There was no geographic influence in the percentage of self-citations to total citations thus indicating a healthy dental scientific publishing environment. Copyright © 2015 Elsevier Inc.
