    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

    Full Text Available This research analyzed the coverage of online news portals during the election campaign in Malaysia's 13th General Election on 5th May 2013. There were two types of news portals chosen for this research: 1 the mainstream online news portals, namely The Star Online, Berita Harian Online, Bernama Online and Utusan Online; and 2 the alternative news portals consisting of political parties' publications: the Harakah Daily, Roketkini and Keadilan Daily; and the independent news portals of The Malaysian Insider and Malaysiakini. This study was conducted starting from the nomination day on the 20th April 2013 until the polling day on the 5th May 2013. Results obtained were based on the frequencies of articles covering the ruling Barisan Nasional (BN party and the opposition Pakatan Rakyat (PR party. Each article was coded and labeled as positive, negative, or neutral coverage for each political party. The Content Analysis method was applied where the researchers chose and analyzed each election article and placed it in one of five categories; +BN (positive report, −BN (negative report, +PR (positive report, −PR (negative report and N (Neutral. The results showed that the four mainstream online news portals favored the BN with their coverage. However, the parties' online news portals clearly owned by PR alliance parties had completely opposite, bias toward their owners. The two independent news portals seemed to give more balanced coverage to both sides.

  4. Masculinity discourse on media text: A critical review about news about violence on online news portals

    Full Text Available Media as a medium plays a significant role in strengthening gender concept in society. Female’s sexualities are viewed as an object of judgement for the media. For the sake of men readers’ satisfaction, media justifies itself in its attempts to exploit women sexuality. Masculine’s way of thinking has been perpetuated in reports about women. Masculine men are considered empowering female’s bodies. Violence acts are considered as the form of masculine domination over feminine beings. This research aims to dismantle how media construct their texts on masculine discourses on online news portals. Online news portals are required to be swift in uploading news and using their acquired resources; thus, they perpetuate this masculine discourse. Critical discourse analysis of Van Dick was employed to unravel masculine discourse structures on media texts at the largest news portals in Indonesia, Alexa.com; and Tribunnews.com; which belong to a corporate media, Kompas Gramedia. The findings of this research state that online news portals and their acquired resources strengthen violence labelling as a part of masculine domination over feminine beings.

    Patient portals have shown potential for increasing health care quality and efficiency. Internet access and other factors influencing patient portal use could worsen health disparities. Observational study of adults with 1 or more visits to the outpatient clinics of an urban public health care system from 2012 to 2015. We used mixed effects logistic regression to evaluate the association between broadband internet access and (1) patient portal initiation (whether a patient logged in at least 1 time) and (2) messaging, controlling for demographic and neighborhood characteristics. There were 243 248 adults with 1 or more visits during 2012-2015 and 70 835 (29.1%) initiated portal use. Portal initiation was 34.1% for whites, 23.4% for blacks, and 23.8% for Hispanics, and was lower for Medicaid (26.5%), Medicare (23.4%), and uninsured patients (17.4%) than commercially insured patients (39.3%). In multivariate analysis, both initiation of portal use (odds ratio [OR] = 1.24 per quintile, 95% confidence interval [CI], 1.23-1.24, P  internet access. The majority of adults with outpatient visits to a large urban health care system did not use the patient portal, and initiation of use was lower for racial and ethnic minorities, persons of lower socioeconomic status, and those without neighborhood broadband internet access. These results suggest the emergence of a digital divide in patient portal use. Given the scale of investment in patient portals and other internet-dependent health information technologies, efforts are urgently needed to address this growing inequality. © The Author 2017.

    Hierarchical organization is prevalent in networks representing a wide range of systems in nature and society. An important example is given by the tag hierarchies extracted from large on-line data repositories such as scientific publication archives, file sharing portals, blogs, on-line news portals, etc. The tagging of the stored objects with informative keywords in such repositories has become very common, and in most cases the tags on a given item are free words chosen by the authors independently. Therefore, the relations among keywords appearing in an on-line data repository are unknown in general. However, in most cases the topics and concepts described by these keywords are forming a latent hierarchy, with the more general topics and categories at the top, and more specialized ones at the bottom. There are several algorithms available for deducing this hierarchy from the statistical features of the keywords. In the present work we apply a recent, co-occurrence-based tag hierarchy extraction method to sets of keywords obtained from four different on-line news portals. The resulting hierarchies show substantial differences not just in the topics rendered as important (being at the top of the hierarchy) or of less interest (categorized low in the hierarchy), but also in the underlying network structure. This reveals discrepancies between the plausible keyword association frameworks in the studied news portals.

    Online access to health records and the ability to exchange secure messages with physicians can improve patient engagement and outcomes; however, the digital divide could limit access to web-based portals among disadvantaged groups. To understand whether sociodemographic differences in patient portal use for secure messaging can be explained by differences in internet access and care preferences. Cross-sectional survey to examine the association between patient sociodemographic characteristics and internet access and care preferences; then, the association between sociodemographic characteristics and secure message use with and without adjusting for internet access and care preference. One thousand forty-one patients with chronic conditions in a large integrated health care delivery system (76% response rate). Internet access, portal use for secure messaging, preference for in-person or online care, and sociodemographic and health characteristics. Internet access and preference mediated some of the differences in secure message use by age, race, and income. For example, using own computer to access the internet explained 52% of the association between race and secure message use and 60% of the association between income and use (Sobel-Goodman mediation test, Pdifferences in portal use remained statistically significant when controlling for internet access and preference. As the availability and use of patient portals increase, it is important to understand which patients have limited access and the barriers they may face. Improving internet access and making portals available across multiple platforms, including mobile, may reduce some disparities in secure message use.

    Full Text Available This paper demonstrates that digital tools provide opportunities for new storytelling techniques. To take full advantage of the new media resources and to establish an innovative news narrative structure, the existing research limit and the relationship between narrative and the media were examined. This paper progresses from a discussion on the narrative structure to how the plot of a story is influenced by its discourse, and then to how different media characteristics can change the structure and voice of the involved narrative. A new narrative structure that can be used to explore the hypertext and interactivity of Internet news is described. Finally, this paper discusses the cultivation of news storytelling in the digital age.

    Full Text Available La denominación de portal en el ámbito de Internet es de uso relativamente reciente y fue iniciada primero por los norteamericanos, siendo su significado en inglés y en español casi el mismo. Aunque originalmente el portal ha pretendido ser la página de entrada a Internet, la que un usuario usa para entrar a navegar por Internet, con la actual proliferación de portales, podríamos decir que esta definición se usa para referirse a una página web que hace las funciones de pórtico de entrada a un espacio informativo temático (a veces de gran alcance, es decir, de un conglomerado de múltiples temas, con lo que se pretende homologar el mundo virtual de Internet con los espacios sociales y culturales de la vida real.

    To assess the use of Internet-based portals among families of children with chronic diseases and to describe characteristics of portal registrants and users. Retrospective observational study. Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, using data from September 1, 2003, through February 29, 2008. Patients/ Parents of children with diabetes mellitus, juvenile idiopathic arthritis, or cystic fibrosis. Parents of children with a chronic disease were given the opportunity to access health-related information for their children via an Internet-based portal. Percentage of families who obtained a portal account (registered), used the portal for the first time within 3 months and again 3 to 6 months after registration, number of times logged in, and session length. Of 1900 families, 27.9% obtained a portal account. Of those, 47.8% used the portal within 3 months of registration and 15.9% continued to use the portal 3 to 6 months after registration. Families of African American patients and of patients insured by Medicaid were less likely to obtain a portal account. More outpatient visits and having private health insurance coverage were associated with increased portal registration and use. Understanding the feasibility of portal use by parents is an important first step to using portals for improving self-management, patient-provider interactions, and outcomes for children with chronic diseases. Subsequent studies should address parent perceptions of the value portals add to the management of the chronic disease of their child and ways to increase that value. Barriers to using portals among racial minorities and publicly insured families should also be studied to address disparities.

    Full Text Available Background. The question whether old media are driven out of existence by new media has been a long concern in academic and industrial research but has received no definitive answer. Aim.This paper goes beyond most previous studies of Internet impact on traditional media, which have placed their relationship within a competition-based framework, to specifically investigate the complementary effect of online news and information usage on traditional sources. Method. Secondary data analysis of a national survey of 4270 Australians conducted in late 2003, employing hypothesis testing for the mean, partial correlations, and a linear regression analysis. Results. Online news and information usage at different usage levels is positively associated with the use of traditional news and information sources, especially those that are more information-intensive. Those who relied on the Internet the most for news and information still used traditional sources substantially. Conclusion. The findings suggest that even if a displacement effect takes place, there will be no replacement (absolute displacement: traditional media will still exist to complement the Internet in serving human beings' news and information needs.

    The importance of herd health management in Switzerland, its implementation by veterinarians as well as their willingness to collaborate within an Internet portal have been assessed by a questionnaire. The portal is meant to serve the genetic evaluation, the veterinary herd health management and the obligation to record treatments; it should be at disposal for all users in form of a central database. For the survey, questionnaires were sent to 784 veterinarians (mixed and livestock practices) in Switzerland. Amongst them, 217 (27.7 %) questionnaires could be evaluated. 125 veterinarians already offer a herd health management service and 147 veterinarians are inclined to collaborate in a central registration of animal health data. In this context, they are interested in an efficient veterinary herd health management program, which will allow direct exchange of data with farmers via an Internet portal. However, they fear a lack of interest of their customers and express some concern regarding data protection. The portal providers must therefore consider the needs of all potential users in order to succeed in this project. At this condition, the veterinarians are prepared to spread herd health management amongst the breeders by means of the animal health portal.

    The personalization in knowledge portals and knowledge management systems is mainly performed based on users' explicitly specified categories and keywords. The explicit specification approach requires users' participation to start personalization services, and has limitation to adapt changes of users' preference. This paper suggests two implicit personalization approaches: automatic user category assignment method and automatic keyword profile generation method. The performances of the implicit personalization approaches are compared with traditional personalization approach using an Internet news site experiment. The result of the experiment shows that the suggested personalization approaches provide sufficient recommendation effectiveness with lessening users'unwanted involvement in personalization process.

    The authors investigated use of the internet-based patient portal, kp.org, among a well-characterized population of adults with diabetes in Northern California. Among 14,102 diverse patients, 5671 (40%) requested a password for the patient portal. Of these, 4311 (76%) activated their accounts, and 3922 (69%), logged on to the patient portal one or more times; 2990 (53%) participants viewed laboratory results, 2132 (38%) requested medication refills, 2093 (37%) sent email messages, and 835 (15%) made medical appointments. After adjustment for age, gender, race/ethnicity, immigration status, educational attainment, and employment status, compared to non-Hispanic Caucasians, African-Americans and Latinos had higher odds of never logging on (OR 2.6 (2.3 to 2.9); OR 2.3 (1.9 to 2.6)), as did those without an educational degree (OR compared to college graduates, 2.3 (1.9 to 2.7)). Those most at risk for poor diabetes outcomes may fall further behind as health systems increasingly rely on the internet and limit current modes of access and communication.

    Evaluation on Internet portals is a key component of any online resource development. Understanding user information seeking behaviour and user perceived behaviour is essential to obtain the full picture of user needs, online activities and draw lessons to improve the design of Internet portals to better meet user expectations. This article discusses the evaluation of a WHO Internet portal: the Labresources website. The evaluation investigates user satisfaction with the resource, usability, demographic information about users and how well they could complete specific tasks using the website and compared this with the actual online behaviour revealing a number of discrepancies. An online questionnaire was advertised on the Labresources website during the period 25 November 2005 to 20 February 2006. As the site caters to English and French speakers, the questionnaire was made available in both languages. It consisted of two sections - the first section required the participant to complete three tasks using the website whereas the second section tested user satisfaction, information needs and appropriateness of the content. Weblogs data were compared with the questionnaire results to compare user perceived and actual online behaviour. Twenty one respondents completed the online questionnaire from a total of 18 countries. This was out of a potential 60 website users among whom the questionnaire was promoted. In general, respondents were satisfied with the website layout and navigation. 61.9% of respondents listed WHO among their top 5 and a third listed the Labresources website. The number of sessions where users browse (146) the information resources is almost three times more than the number of users who search (52) the resources. Weblogs revealed most interesting results with differences between what users reported doing when completing tasks and how easy they perceived the tasks and what they actually did. Twelve respondents completed at least one task. Of the

    The aim of this study is to discuss how information about the development and use of bio-energy is forwarded and disseminated to general public via the Internet in China. Furthermore, this study also explores in what manner the information of renewable energy policies is presented. A research method used in this study is an application of content analysis. Altogether 19 energy-related web platforms were found by searching keywords, such as 'energy net' or 'renewable energy net' or 'bio-energy net' on (www.Google.cn). A thorough analysis was conducted by focusing on one of them: (www.china5e.com). The news articles on (www.china5e.com) were examined according to whether the use of bio-energy was articulated positively or negatively in the contents of articles. It was also considered whether the articles were imported from abroad. The results of this study indicated that in China there is a tendency on the Internet to disseminate primarily the positive information about bio-energy with a great emphasis on its benefits. In addition, the study shows that when analyzing the content of the news articles, biogas and liquid bio-fuels will be the main bio-energy development trends in China in the near future.

    Full Text Available Internet media have an influence on many tourism-related issues. This article presents the results of research into the role of tourism-themed portals in the trips taken by Polish university students between 2010 and 2012. The research sought to answer the following questions: whether tourism-related internet media have an influence on the students’ behaviour before, during the trip and when they arrive at their destination; how often they are used by the respondents during their trips; and whether Polish students actively participate in internet media by voicing their opinions. As it appears, internet media serve as one of the “travel companions” for young people. They are used when preparing the trip, the vast majority “take them” with them and check them during the trip, while almost half of them check them on vacation, e.g. to share their experience over the internet.

    Use of the World Wide Web (WWW) and electronic media to facilitate medical care has been the subject of many reports in the popular press. However, few reports have documented the results of implementing electronic health portals for essential medical tasks, such as prescription refills and appointments. At Walter Reed Army Medical Center, "Search & Learn" medical information, Internet-based prescription refills and patient appointments were established in January 2001. A multiphase retrospective analysis was conducted to determine the use of the "Search & Learn" medical information and the relative number of prescription refills and appointments conducted via the WWW compared with conventional methods. From January 2001 to May 2002, there were 34,741 refills and 819 appointments made over the Internet compared with 2,275,112 refills and approximately 500,000 appointments made conventionally. WWW activity accounted for 1.52% of refills and 0.16% of appointments. There was a steady increase in this percentage over the time of the analysis. In April of 2002, the monthly average of online refills had risen to 4.57% and online appointments were at 0.27%. Online refills were projected to account for 10% of all prescriptions in 2 years. The "Search & Learn" medical information portion of our web site received 147,429 unique visits during this same time frame, which was an average of 326 visitors per day. WWW-based methods of conducting essential medical tasks accounted for a small but rapidly increasing percentage of total activity at Walter Reed Army Medical Center. Subsequent phases of analysis will assess demographic and geographic factors and aid in the design of future systems to increase use of the Internet-based systems.

    At the onset of the new millennium the Internet has become the new standard means of distributing information. In the last two to three years there has been an explosion of e-commerce with hundreds of new web sites being created every minute. For most corporate entities, a web site is as essential as the phone book listing used to be. Twenty years ago technologist directed how computer-based systems were utilized. Now it is the end users of personal computers that have gained expertise and drive the functionality of software applications. The computer, initially invented for mathematical functions, has transitioned from this role to an integrated communications device that provides the portal to the digital world. The Web needs to be used by healthcare professionals, not only for professional activities, but also for instant access to information and services "just when they need it." This will facilitate the longitudinal use of information as society continues to gain better information access skills. With the demand for current "just in time" information and the standards established by Internet protocols, reference sources of information may be maintained in dynamic fashion. News services have been available through the Internet for several years, but now reference materials such as online journals and digital textbooks have become available and have the potential to change the traditional publishing industry. The pace of change should make us consider Will Rogers' advice, "It isn't good enough to be moving in the right direction. If you are not moving fast enough, you can still get run over!" The intent of this article is to complement previous articles on Internet Resources published in this journal, by presenting information about web sites that present information on computer and Internet technologies, reference materials, news information, and information that lets us improve personal productivity. Neither the author, nor the Journal endorses any of the

    E-health is an emerging field on the intersection of medical information technologies, public health and business, referring to health services and information delivered or enhanced through the Internet and related technologies. Portal technology, allowing services to be accessible over the Internet is a perfect tool for providing e-health services. The use of portal technologies has had deep influence on the architecture of the whole e-health system, both regarding new subsystems and older ones which we want to integrate with the portal. Portals provide new possibilities for creating novel types of e-health applications as well. In this paper we provide a brief overview of e-health systems and portal technologies, and present many technical aspects of portal technology application for e-health systems such as the architecture of portal-based e-health systems, graphical user interfaces, access to various e-health systems' resources, personalization, security and privacy.

    We construct a news spreading model with a time dependent contact rate which generalizes the classical Susceptible-Infected model of epidemiology. In particular, we are interested on the time-dynamics of the sharing and diffusion process of news on the Internet. We focus on the counting process describing the number of connections to a given website, characterizing the cumulative density function of its inter-arrival times. Moreover, starting from the general form of the finite dimensional distribution of the process, we determine a formula for the time-variable rate of the connections and establish its relationship with the probability density function of the interarrival times. We finally show the effectiveness of our theoretical framework analyzing a real-world dataset, the Memetracker dataset, whose parameters characterizing the diffusion process are determined.

    There are multiple ways in which community pharmacies can present themselves on the Internet, e.g., as a platform for drug information or as an advertising platform for their services. To estimate the number of Swiss community pharmacies on the Internet over the period of 32 months (2000-2003), to describe their current e-commerce services, and to explore the experiences and plans these pharmacies have with regard to their Internet presence. A longitudinal study was performed to determine the number of Swiss German pharmacies on the Internet by conducting Internet searches in 2000, 2001, and 2003. In April 2002, a cross-sectional Internet-based survey was administered to explore the pharmacies' experiences and plans regarding their Web sites. As of April 2003, 373 (44%) of 852 community pharmacies from the German speaking part of Switzerland were on the Internet. One hundred eighty four listed an e-mail address and were asked to complete a questionnaire. Of the 107 pharmacies answering the survey questions (58% response rate): 46% had been on the Internet for 1 to 2 years; 33% of the Web sites are part of a pharmacy group's Web portal; 31% of the pharmacies plan to expand their Internet appearance in the future; 74% provide e-commerce services, with 81% of those pharmacies filling five or less orders per month; and 12% plan on expanding their e-commerce services in the future. The number of community pharmacies offering Internet services steadily increased over 32 months. Given the importance of the Internet as a tool for information, communication, and advertising for pharmacy products and services, it can be expected that the increase will continue. Pharmacy-group portals are important promoters of pharmacies on the Internet. For many community pharmacies, Internet portals that provide an Internet presence for the pharmacies and provide regularly-updated content (e.g., health news, tips, drug information) seem to be the most effective solutions.

    Electronic patient portals give patients access to personal medical data, potentially creating opportunities to improve knowledge, self-efficacy, and engagement in healthcare. The combination of knowledge, self-efficacy, and engagement has been termed activation. Our objective was to assess the relationship between patient activation and outpatient use of a patient portal. Survey. A telephone survey was conducted with 180 patients who had been given access to a portal, 113 of whom used it and 67 of whom did not. The validated patient activation measure (PAM) was administered along with questions about demographics and behaviors. Portal users were no different from nonusers in patient activation. Portal users did have higher education level and more frequent Internet use, and were more likely to have precisely 2 prescription medications than to have more or fewer. Patients who chose to use an electronic patient portal were not more highly activated than nonusers, although they were more educated and more likely to be Internet users.

    Human papilloma virus vaccines are a safe and effective tool for reducing HPV infections that can cause cervical cancer. However, uptake of these vaccines has been suboptimal, with many people holding negative beliefs and misconceptions. Such beliefs have been linked with the experience of unpleasant side effects following medical treatment, and media coverage may heighten such concerns. The present study sought to assess the influence of news coverage (number of news articles per month) on adverse event reporting in response to Gardasil vaccination in New Zealand over a 7.5-year period, and whether the influence of news coverage was mediated by internet search activity (Google search volumes). Multiple linear regression analyses and simple mediation analyses were used, controlling for year and number of vaccinations delivered. News coverage in the previous month, and Google search volumes in the same month, were significant predictors of adverse event reporting, after accounting for vaccination rates and year. Concurrent Google search volumes partially mediated the effect of prior news coverage. The results suggest that some of the adverse events reported were not related to the vaccination itself, but to news coverage and internet search volumes, which may have contributed to public concerns about potentially unpleasant or harmful outcomes. These findings have implications for the importance of psychological and social factors in adverse event reporting, and the role of the news media in disseminating health information.

    2017-01-01

    Full Text Available The online news media are said to have changed the understanding of the gatekeeping theory. Due to the virtually unlimited news space together with the interactivity in the online presentation of news, the Internet defies the whole conception of gatekeeping in journalism. This article seeks to examine the influence of gatekeeping forces in two influential Malaysian online news portals, MalaysiaKini and The Malaysian Insider (TMI, during the 2013 Malaysian general election. Based on the hierarchical model of news conception, this study assessed the influence of ideological gatekeeping forces on their news content. The reporting by both news portals was subjected to qualitative textual analysis. The results are triangualted with interviews with corresponding reporters and editors from MalaysiaKini and TMI. The findings show that although the reporting of MalaysiaKini and TMI is counter-ideological, the gatekeeping process remains intact. This is due to the speed factor and the requirement of the news portals to abide by the media-related laws in Malaysia.

    Full Text Available This work shows the development of audiovisual webjournalism on the Brazilian Internet. This paper, based on the analysis of UOL News on UOL TV – pioneer format on commercial web television - and of UERJ Online TV – first on-line university television in Brazil - investigates the changes in the gathering, production and dissemination processes of audiovisual news when it starts to be transmitted through the web. Reflections of authors such as Herreros (2003, Manovich (2001 and Gosciola (2003 are used to discuss the construction of audiovisual narrative on the web. To comprehend the current changes in today’s webjournalism, we draw on the concepts developed by Fidler (1997; Bolter and Grusin (1998; Machado (2000; Mattos (2002 and Palacios (2003. We may conclude that the organization of narrative elements in cyberspace makes for the efficiency of journalistic messages, while establishing the basis of a particular language for audiovisual news on the Internet.

    Online news articles,as a new format of press releases,have sprung up on the Internet.With its convenience and recency,more and more people prefer to read news online instead of reading the paper-format press releases.However,a gigantic amount of news events might be released at a rate of hundreds,even thousands per hour.A challenging problem is how to efficiently select specific news articles from a large corpus of newly-published press releases to recommend to individual readers,where the selected news items should match the reader's reading preference as much as possible.This issue refers to personalized news recommendation.Recently,personalized news recommendation has become a promising research direction as the Internet provides fast access to real-time information from multiple sources around the world.Existing personalized news recommendation systems strive to adapt their services to individual users by virtue of both user and news content information.A variety of techniques have been proposed to tackle personalized news recommendation,including content-based,collaborative filtering systems and hybrid versions of these two.In this paper,we provide a comprehensive investigation of existing personalized news recommenders.We discuss several essential issues underlying the problem of personalized news recommendation,and explore possible solutions for performance improvement.Further,we provide an empirical study on a collection of news articles obtained from various news websites,and evaluate the effect of different factors for personalized news recommendation.We hope our discussion and exploration would provide insights for researchers who are interested in personalized news recommendation.

    Maternity patients interact with the healthcare system over an approximately ten-month interval, requiring multiple visits, acquiring pregnancy-specific education, and sharing health information among providers. Many features of a web-based patient portal could help pregnant women manage their interactions with the healthcare system; however, it is unclear whether pregnant women in safety-net settings have the resources, skills or interest required for portal adoption. In this study of postpartum patients in a safety net hospital, we aimed to: (1) determine if patients have the technical resources and skills to access a portal, (2) gain insight into their interest in health information, and (3) identify the perceived utility of portal features and potential barriers to adoption. We developed a structured questionnaire to collect demographics from postpartum patients and measure use of technology and the internet, self-reported literacy, interest in health information, awareness of portal functions, and perceived barriers to use. The questionnaire was administered in person to women in an inpatient setting. Of the 100 participants surveyed, 95% reported routine internet use and 56% used it to search for health information. Most participants had never heard of a patient portal, yet 92% believed that the portal functions were important. The two most appealing functions were to check results and manage appointments. Most participants in this study have the required resources such as a device and familiarity with the internet to access a patient portal including an interest in interacting with a healthcare institution via electronic means. Pregnancy is a critical episode of care where active engagement with the healthcare system can influence outcomes. Healthcare systems and portal developers should consider ways to tailor a portal to address the specific health needs of a maternity population including those in a safety net setting.

  2. The Concept of Credibility (Validity in Television and Internet News Discourse: Critical Analysis

    2010-12-01

    Full Text Available This article reverses the traditional notion of media (television, radio or news papers as a unidirectional agent of communication from producer to receiver to a more appropriate paradigm inwhich information is not embedded with hierarchy. The new media perspective and the appropriation of technology (Internet have changed the nature of information dissemination. One cannot discuss authenticity or credibility in terms of ”telling the truth or lying”. On the contrary, users today can verify information by contrasting traditional media, or by autonomous investigation on the Internet. In this manner, the obtained information is rendered semantically ambiguous. With an approach akin to cultural studies, the authority of the speakers becomes important (unlike today in mainstream television media where a speaker is hidden behind his or her program. New media provides a unique perspective in which the user is always the arbiter of informational usefulness. The crisis that is manifested in traditional media by the lack of subjectivity of the reporter becomes diametrically opposite on the Internet. The all-knowing subject vanishes and gives place to an inter-subjective exchange which deletes hierarchy and the ontology of the ”truth”. A mirror perspective becomes the dominant order, by which one becomes inter-subjective par excellence. Within the present and future of new media, credibility will not be reserved for the ideological mass producers of information, but rather the credibility of the users. By becoming media, users begin to bear the burden of subjective analysis and multivocality.

    The Portal for Families Overcoming Neurodevelopmental Disorders (PFOND) provides a structured Internet interface for the sharing of information with individuals struggling with the consequences of rare developmental disorders. Large disease-impacted communities can support fundraising organizations that disseminate Web-based information through elegant websites run by professional staff. Such quality resources for families challenged by rare disorders are infrequently produced and, when available, are often dependent upon the continued efforts of a single individual. The project endeavors to create an intuitive Web-based software system that allows a volunteer with limited technical computer skills to produce a useful rare disease website in a short time period. Such a system should provide access to emerging news and research findings, facilitate community participation, present summary information about the disorder, and allow for transient management by volunteers who are likely to change periodically. The prototype portal was implemented using the WordPress software system with both existing and customized supplementary plug-in software modules. Gamification scoring features were implemented in a module, allowing editors to measure progress. The system was installed on a Linux-based computer server, accessible across the Internet through standard Web browsers. A prototype PFOND system was implemented and tested. The prototype system features a structured organization with distinct partitions for background information, recent publications, and community discussions. The software design allows volunteer editors to create a themed website, implement a limited set of topic pages, and connect the software to dynamic RSS feeds providing information about recent news or advances. The prototype was assessed by a fraction of the disease sites developed (8 out of 27), including Aarskog-Scott syndrome, Aniridia, Adams-Oliver syndrome, Cat Eye syndrome, Kabuki syndrome

    Full Text Available We describe a method whereby a governmental policy maker can discover citizens’ reaction to news stories. This is particularly relevant in the political world, where governments’ policy statements are reported by the news media and discussed by citizens. The work here addresses two main questions: whereabouts are citizens discussing a news story, and what are they saying? Our strategy to answer the first question is to find news articles pertaining to the policy statements, then perform internet searches for references to the news articles’ headlines and URLs. We have created a software tool that schedules repeating Google searches for the news articles and collects the results in a database, enabling the user to aggregate and analyse them to produce ranked tables of sites that reference the news articles. Using data mining techniques we can analyse data so that resultant ranking reflects an overall aggregate score, taking into account multiple datasets, and this shows the most relevant places on the internet where the story is discussed. To answer the second question, we introduce the WeGov toolbox as a tool for analysing citizens’ comments and behaviour pertaining to news stories.  We first use the tool for identifying social network discussions, using different strategies for Facebook and Twitter. We apply different analysis components to analyse the data to distil the essence of the social network users’ comments, to determine influential users and identify important comments.

    Full Text Available This study aims to explore how directly or indirectly control policies of Turkish political government towards media besides the ownership relations of the media affect the newsmaking process. After 1980, Turkey experienced media concentration and media commercialism as a result of neoliberal policies. Though media concentration is a global phenomenon, the process has its own characteristics in Turkey. Free market is not supposed to have given rise to the birth of a free press. Intervention in relations and clientelism between the government and the media in history have merged with a rapid commercialism. This study examines the newsmaking process with the political economy approach on the basis of the ownership structure and the relations between the media and the government. The study covers an analysis of 14 digital news portals based on their headlines between the dates 20-26 January 2015 and the hours 8:00 am. -11:00 pm.  The data obtained indicate a similarity between the news portals in terms of topics agendas, and news discourse.

    With the advent of specialized television channels offering 24-hour coverage, Internet and smart phones, the possibility to be constantly in contact with the media has increased dramatically in the last decades. Despite this higher access to knowledge, the impact media exposure has on healthy individuals remains poorly studied. Given that most information conveyed in the media is negative and that upon perception of threat, the brain activates the stress system, which leads to cortisol secretion, we decided to determine how healthy individuals react to media information. Accordingly, we investigated whether reading real negative news (1) is physiologically stressful, (2) modulates one's propensity to be stress reactive to a subsequent stressor and (3) modulates remembrance for these news. Sixty participants (30 women, 30 men) were randomly assigned to either twenty-four real neutral news excerpts or to twenty-four real negative excerpts for 10 minutes. They were then all exposed to a well-validated psychosocial stressor, the Trier Social Stress Test (TSST), which consists of an anticipation phase of 10 minutes and a test phase of 10 minutes. A total of eight salivary cortisol samples were collected, at 10-minutes intervals, throughout the experimental procedure. One day later, a free recall of the news was performed. Results showed that although reading negative news did not lead to change in cortisol levels (p>0.05), it led to a significant increase in cortisol to a subsequent stressor in women only (pnegative news condition experienced better memory for these news excerpts compared to men (pmedia exposure could increase stress reactivity and memory for negative news in women.

    Newspapers are operating in increasingly competitive and fragmented markets for audiences and advertising revenues, government media policy and changing audience requirements for news and the ways in which it is presented and delivered. A growing army of bloggers and amateur citizen journalists now delivers - but rarely edits - content for all media platforms, while new media technologies, combined with the changing structure of global news industries, are radically changing the ways in which newspapers and media business functions and struggles for profitability. Our research sought to answer the question of how the internet is impacting on producer/consumer value activities in the news media supply chain. To answer this question initial descriptive statistical analysis was performed on 51 newspapers. This was followed by a focus group undertaken with London-based news media organizations and bloggers. The findings showed that in spite of initial fear and rejection, the internet is now firmly embedded in news media supply chain operations. Firms are now using the internet as an operant resource and working proactively with consumers to develop various forms of relationship value. We highlight the role of consumers in the creation of news (editorial) content and consumer-driven moves toward a merged media platform of distribution (including television, online, mobile and printed forms). Regional news media organizations will probably continue to survive if they are able to supply a highly specialized and 'hyper local' community service. This will be in the form of 'hybrid' content: analysis, interpretation and investigative reporting in a print product that appears less than daily combined with constant updating and reader interaction on the web.

    Full Text Available In the past few years considerable demand for business oriented multimedia information systems has developed. A multimedia information system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full-motion video, and text information. Multimedia information systems play a central role in many business activities. They represent a very special class complex computing systems. This paper surveys a special type of multimedia information systems: multimedia news systems. Multimedia news systems deal with architectures to manage complex multimedia news databases, online presentation and distribution services or the integration of several existing services to meta-services using intelligent news retrieval engines. The leading presentation platform in multimedia news presentation is news networks providing television services and Internet content distribution. The primary focus is on advanced multimedia news systems infrastructure, document standards, application architecture and principles for multimedia news on the Web that suggest long-term trends in this increasingly important area.

To grab attentions to news, news services use a number of criteria that called news values and user location is an important factor for it. In this paper, LONEF is proposed as a tow stage recommendation system. In first stage news are ranked by user’s locations and in second stage news are recommended by location Preferences, recency, Trustworthiness, groups priorities and popularity. To reduce ambiguity these properties is used tow Mamdani fuzzy interference and case-based decision systems. In Mamdani fuzzy interference system, it is tried to increase the system speed by optimizing selection of rules and membership functions and because of ambiguous feedback implementation, a decision making system is used to enable better simulation of user’s activities. Performance of our proposed approach is demonstrated in the experiments on different news groups.

    2014-10-01

    Full Text Available Online videos, or so called user-generated content, have been used in TV news frequently because of recent media convergence. This study examined whether this phenomenon influences news routines, and whether new characteristics of news routines have emerged because of the dependency on UGC sources. A qualitative research method was adopted, and 15 Taiwanese TV journalists were interviewed. The results show that the high dependence on the Internet for obtaining news has encouraged journalists producing news without having to leave newsroom. New routines have been formed in new production. At organizational levels, the search for online materials has been routinized, Journalist’ newsgathering and reporting are no longer original and initial but follow the hit topics on the Internet, Moreover, and news coverage currently focuses on format instead of meaning. At interorganizational level, TV news organizations monitor and imitate each other to adjust their routines. This paper shows that some unprofessional behaviors of journalists have become reasonable because of news routines changed. Consequently, the ethical and professional controversies have been ignored in newsroom.

    Web Portals function as a single point of access to information on the World Wide Web (WWW). The web portal always contacts the portal's gateway for the information flow that causes network traffic over the Internet. Moreover, it provides real time/dynamic access to the stored information, but not access to the real time information. This inherent functionality of web portals limits their role for resource constrained digital devices in the Ubiquitous era (U-era). This paper presents a framework for the web portal in the U-era. We have introduced the concept of Local Regions in the proposed framework, so that the local queries could be solved locally rather than having to route them over the Internet. Moreover, our framework enables one-to-one device communication for real time information flow. To provide an in-depth analysis, firstly, we provide an analytical model for query processing at the servers for our framework-oriented web portal. At the end, we have deployed a testbed, as one of the world's largest IP based wireless sensor networks testbed, and real time measurements are observed that prove the efficacy and workability of the proposed framework.

    Full Text Available Finding good and relevant information in crime news is one of the most challenging tasks faced by users. An increase in the amount of information from news media has caused difficulties for users in obtaining relevant information. Hence, visualization is one of the important aspects to enhance user’s understanding when browsing or searching for news. Crime news requires a proper approach to visualize a variety of important information such as suspect, victim, location, time and evidence. Visual navigation is more interactive than linear. This has motivated us to develop a prototype called Crime News Visualization (CNV, which mplements a timeline and tree viewer to assist users when browsing crime news chronologically. The prototype follows several phases of development starting with design concept, implementation and evaluation. News corpus used in this study is from the Bernama Library & Infolink Service (BLIS resource, with a sample of 247 crime news documents from year 1997 to 2012. A user experiment was conducted with 20 undergraduate students from the Faculty of Social Science and Humanities, Universiti Kebangsaan Malaysia in order to evaluate the acceptance and perception of interactive browsing of crime news using news portal (baseline and CNV (experimental. Findings revealed that more than 90% of the respondents indicated that the use of timeline visualization and tree viewer was helpful and had potential to improve the way users browse for crime news content.

This portal joins two theme networks of virtual and remote laboratories (one for Control Engineering and another one for Physics, named AutomatL@bs and FisL@bs, respectively together. AutomatL@bs has been operative for five years now. Following AutomatL@bs’ scheme, FisL@bs was created as a network of remote and virtual laboratories for physics university education via the Internet to offer students the possibility of performing hands-on experiences in different fields of physics in two ways: simulation and real remote operation. Now, both FisL@bs and AutomatL@bs join together (while maintaining their independency into an unique new web portal called UNEDLabs. This work focuses on this new web environment and gives a detailed account of a novel way in Physics to let distance learning students gain practical experience autonomously. This paper explains how the new portal works and the software tools used for creating it. In addition, it also describes the physics experiments which are already operative.

    Effective management and care of diabetes is crucial to reducing associated risks such as heart disease and kidney failure. With increasing access and use of the Internet, online chronic disease management is being explored as a means of providing patients with support and the necessary tools to monitor and manage their disease. The objective of our study was to evaluate the experience of patients and providers using an online diabetes management portal for patients. Participants were recruited from a large sample population of 887 for a follow-up questionnaire to be completed after 6 months of using the patient portal. Participants were presented with the option to participate in an additional interview and, if the participant agreed, a time and date was scheduled for the interview. A 5-item, open-ended questionnaire was used to capture providers' opinions of the patient portal. Providers included general practitioners (GPs), nurses, nurse practitioners (NPs), dieticians, diabetes educators (DECs), and other clinical staff. A total of 854 patients were consented for the questionnaire. Seventeen (8 male, 9 female) patients agreed to participate in a telephone interview. Sixty-four health care providers completed the five open-ended questions; however, an average of 48.2 responses were recorded per question. Four major themes were identified and will be discussed in this paper. These themes have been classified as: facilitators of disease management, barriers to portal use, patient-provider communication and relationship, and recommendations for portal improvements. This qualitative study shows that online chronic disease management portals increase patient access to information and engagement in their health care, but improvements in the portal itself may improve usability and reduce attrition. Furthermore, this study identifies a grey area that exists in the roles that GPs and AHPs should play in the facilitation of online disease management.

    Full Text Available In this research, two estimation algorithms for extracting cross-lingual news pairs based on machine learning from financial news articles have been proposed. Every second, innumerable text data, including all kinds news, reports, messages, reviews, comments, and tweets are generated on the Internet, and these are written not only in English but also in other languages such as Chinese, Japanese, French, etc. By taking advantage of multi-lingual text resources provided by Thomson Reuters News, we developed two estimation algorithms for extracting cross-lingual news pairs from multilingual text resources. In our first method, we propose a novel structure that uses the word information and the machine learning method effectively in this task. Simultaneously, we developed a bidirectional Long Short-Term Memory (LSTM based method to calculate cross-lingual semantic text similarity for long text and short text, respectively. Thus, when an important news article is published, users can read similar news articles that are written in their native language using our method.

    The diffusion of breaking news largely relies on propagation behaviors in the media. The tremendous and intricate propagation relationships in the media form a complex network. An improved understanding of breaking news diffusion characteristics can be obtained through the complex network research. Drawing on the news data of Bohai Gulf oil spill event from June 2011 to May 2014, we constructed a weighted and directed complex network in which media are set as nodes, the propagation relationships as edges and the propagation times as the weight of the edges. The primary results show (1) the propagation network presents small world feature, which means relations among media are close and breaking news originating from any node can spread rapidly; (2) traditional media and official websites are the typical sources for news propagation, while business portals are news collectors and spreaders; (3) the propagation network is assortative and the group of core media facilities the spread of breaking news faster; (4) for online media, news originality factor become less important to propagation behaviors. This study offers a new insight to explore information dissemination from the perspective of statistical physics and is beneficial for utilizing the public opinion in a positive way.

    Shirokova, V. I.; Kolotov, V. P.; Alenina, M. V.

    A new Internet portal developed by community of Russian analysts has been launched in 2001 (http://www.geokhi.ru/~rusanalytchem, http://www.rusanalytchem.org) Corporate Web Portal information, "Analytical Chemistry in Russia" , Corporate Web Portal information, "Analytical Chemistry in Russia" ). Now the portal contains a large amount of information, great part of it is stored in the form of SQL data base (MS SQL). The information retrieval is made by means of ASP pages, containing VB Scripts. The obtained experience of work with such topical portal has detected some weak points, related with its centralized administration and updating. It has been found that urgent supporting of all requests from different persons/organizations on information allocation on the portal's server takes a lot of efforts and time. That is why, the further development of portal we relate with development of a distributed system for information allocation and control, under preserving of centralized administration for ensuring of security and stable working of the portal. Analysis and testing of some available technologies lead us to conclusion to apply MS Share Point technologies. A MS Share Point Team Services (SPTS) has been selected as a technology supporting relatively small groups, where MS SQL is used for storage data and metadata. The last feature was considered as decisive one for SPTS selection, allowing easy integration with data base of the whole portal. SPTS was launched as an independent Internet site accessible from home page of the portal. It serves as a root site to exit to dozens of subsites serving different bodies of Russian Scientific Council on analytical chemistry and external organizations located over the whole Russia. The secure functioning of such hierarchical system, which includes a lot of remote information suppliers, based on use of roles to manage user rights independently for each subsite. The root site is controlled by portal administrator, whereas the

    2015-07-01

    A new method is developed to estimate social influence in Internet communities that follow a specific developing news story. The technique stems from mean-field treatment of magnetic systems and provides a measure for community stability, such as the potential of a small perturbation to culminate in a phase-transition-like phenomenon. Three real cases of developing news stories from CNN news website are analyzed. Continuous dynamics of social influence together with time is observed together with a significant increase of social influence after the announcement of important information, such as the jury decision in a legal case. This work makes it possible to estimate the size of a group that can change the opinion of the entire population. We argue that Internet comments may predict the level of social response similar to a barometer that predicts the intensity of a coming storm in still calm environment.

We aimed to determine whether and how the interpretation of research results is misrepresented by the use of "spin" in the health section of Google News. Spin was defined as specific way of reporting, from whatever motive (intentional or unintentional, to emphasize that the beneficial effect of the intervention is greater than that shown by the results.We conducted a cross-sectional study of news highlighted in the health section of US, UK and Canada editions of Google News between July 2013 and January 2014. We searched for news items for 3 days a week (i.e., Monday, Wednesday, and Friday during 6 months and selected a sample of 130 news items reporting a scientific article evaluating the effect of an intervention on human health.In total, 78% of the news did not provide a full reference or electronic link to the scientific article. We found at least one spin in 114 (88% news items and 18 different types of spin in news. These spin were mainly related to misleading reporting (59% such as not reporting adverse events that were reported in the scientific article (25%, misleading interpretation (69% such as claiming a causal effect despite non-randomized study design (49% and overgeneralization/misleading extrapolation (41% of the results such as extrapolating a beneficial effect from an animal study to humans (21%. We also identified some new types of spin such as highlighting a single patient experience for the success of a new treatment instead of focusing on the group results.Interpretation of research results was frequently misrepresented in the health section of Google News. However, we do not know whether these spin were from the scientific articles themselves or added in the news.

    Full Text Available Web portals have been used as information products to deliver personalized, feature-rich, and flexible information needs to Internet users. However, all portals are not equal. Most of them have relatively a small number of visitors, while a few capture the majority of surfers. This study seeks to uncover the factors that contribute the perceived quality of a general portal. Based on 21 factors derived from an extensive literature review on Information Product Quality (IPQ, web usage, and media use, an experimental study was conducted to identify the factors that are perceived by web portal users as most relevant. The literature categorizes quality factors of an information product in three dimensions: information, physical, and service. This experiment suggests a different clustering of factors: Content relevancy, Communication interactiveness, Information currency, and Instant gratification. The findings in this study will help developers find a more customer-oriented approach to developing high-traffic portals.

    Adolescent Internet gambling is associated with concomitant addictive behaviors. This study aimed to assess the prevalence of Internet gambling practices, its impact upon psychosocial development and to evaluate the association between gambling practices and Internet addictive behavior among Cypriot adolescents. A cross-sectional study was conducted in a convenience sample (n = 805) of adolescents attending selected public schools (9th and 10th grades) in Cyprus. Anonymous self-completed questionnaires were used including the Internet Addiction Test and the Strengths and Difficulties Questionnaire. Among the study population (n = 805), approximately one third (n = 28; 34.9%) reported Internet gambling. Internet gamblers were twice as likely to utilize Internet café portals (adjusted odds ratio for gender and age, AOR: 2.13; 95% confidence interval, 95% CI: 1.56-2.91) for interactive game-playing (AOR: 6.84; 95% CI: 4.23-11.07), chat-rooms (AOR: 2.57; 95% CI: 1.31-4.85), and retrieval of sexual information (AOR: 1.99; 95% CI: 1.42-2.81). Among Internet gamblers 26.0% (n = 73) reported borderline addictive Internet use and 4.3% (n = 12) addictive behavior. Internet gamblers more often had comprehensive psychosocial and emotional maladjustment (AOR: 4.00; 95% CI: 1.97-8.13), including Abnormal Conduct Problems (AOR: 3.26; 95% CI: 2.00-5.32), Emotional Symptoms (AOR: 1.78; 95% CI: 1.02-3.11), and Peer Problems (AOR: 2.44; 95% CI: 1.08-5.48) scores. The multivariate regression analyses indicated that the single independent predictor associated with Internet addictive behavior was Internet gambling (AOR: 5.66; 95% CI: 1.45-22.15). Internet gambling is associated with addictive Internet use, as well as emotional maladjustment and behavioral problems, among Cypriot adolescents. Longitudinal studies are needed to elucidate whether Internet gambling constitutes a risk factor for the development of Internet addictive behavior among adolescents.

    Full Text Available The Internet affords users a unique and low-cost way to engage with news, politics, and one another. Although young people are the most likely age cohort to go online, it is questionable whether young people take advantage of the Internet as a deliberative space. We examine the way college students perceive the online world as a venue for political discussion by analyzing responses from six focus groups conducted with college students across the United States. Using deliberative theory as a guide, we examine focus group participants’ thoughts about political discussion both online and offline. Our findings indicate that young people’s preferences for online discussions about politics and the news consistently link to the ideals of deliberation. Young people prefer engaging with others who are knowledgeable and remain flexible and calm during discussions. Goals for engaging in conversations about politics primarily revolved around sharing information and opinions. Participants preferred civil discourse that focuses on commonalities rather than differences between people. This study provides greater insight into how the rising generation currently engages with politics and the news and reasons why many people hesitate to participate in online discussions about public affairs.

    To evaluate the value of endovascular stent in the treatment of portal hypertension caused by benign main portal vein stenosis. Portal vein stents were implanted in six patients with benign main portal vein stenosis (inflammatory stenosis in three cases, postprocedure of liver transplantation in another three cases). Changes in portal vein pressure, portal vein patency, relative clinical symptoms, complications, and survival were evaluated. Six metallic stents were successfully placed across the portal vein stenotic or obstructive lesions in six patients. Mean portal venous pressure decreased significantly after stent implantation from (37.3+/-4.7) cm H(2)O to (18.0+/-1.9) cm H(2)O. The portal blood flow restored and the symptoms caused by portal hypertension were eliminated. There were no severe procedure-related complications. The patients were followed up for 1-48 mo. The portal vein remained patent during follow-up. All patients survived except for one patient who died of other complications of liver transplantation. Percutaneous portal vein stent placement for the treatment of portal hypertension caused by benign main portal vein stenosis is safe and effective.

    Increasing utilization of the Internet and convenient web technologies has made the web-portal a major application interface for remote participation and control of scientific instruments. While web-portals have provided a centralized gateway for multiple computational services, the amount of visual output often is overwhelming due to the high volume of data generated by complex scientific instruments and experiments. Since each scientist may have different priorities and areas of interest in the experiment, filtering and organizing information based on the individual user's need can increase the usability and efficiency of a web-portal. DIII-D is the largest magnetic nuclear fusion device in the US. A web-portal has been designed to support the experimental activities of DIII-D researchers worldwide. It offers a customizable interface with personalized page layouts and list of services for users to select.

    The recall of the articular surface replacement (ASR) hip prosthesis in 2010 represents one of the most controversial areas in orthopaedic surgery in recent years. The aim of this study was to compare the impact of the metal-on-metal hip controversy on Internet search activity in four different regions and determine whether the number of related news reports affected Internet search activity. The Google Trends, Keywords and News applications were used to record the number of news articles and Internet search activity for the terms "hip recall", "metal-on-metal hip" and "ASR hip" from October 2009 to October 2012 in the USA, the UK, Australia and Ireland. There was a large increase in search activity following the official recall in August 2010 in all countries. There was significantly greater search activity after the recall in Ireland compared with the UK for the search term "hip recall" (P = 0.004). For the term "metal-on-metal hip", the UK had significantly more search activity (P = 0.0009). There was a positive correlation between the number of news stories in UK and Ireland with Internet search activity but not in the USA or Australia. Differences between countries affected by the same recall highlight the complex effects of the media on public awareness. The data demonstrates a window of opportunity prior to the official recall for the development of an awareness campaign to provide patients with accurate information.

    Full Text Available We live in an age that the sources citizens need for news and information are not limited to traditional media. Other than traditional media, internet and internet-based information and communication technologies offer citizens new alternatives in various forms. Internet search engines, which are one of these new technologies, play a significant role in the circulation of news and information regarding social debates, right along with any kind of news and information. However, this brings about the question how search engines’ role plays out in the reflection and conformation of social debates. To investigate this question, this paper examines how the public debate on the “Procedures and Principles for Safe Internet Service” that was taken place in 2011 and 2012 in Turkey, was structured and framed in search engines and the print press by using content analysis.

    2016-01-01

    These days, use of the Internet is unavoidable for the younger generations. The online world is the primary source of infomation and quick communication, and these activities can take many hours per day. The main goal of the present study was to examine the correlations among problematic internet use, social factors, stress and life satisfaction. Data collection was going online during the first semester of the year 2014 (N= 386 girls). The anonymous questionnaire contained items on perceived social support and the amount of online activites beyond sociodemographics. After descriptive statistics, factor, correlation and multiple linear regression analyses were applied to detect interrelationships. According to our data, 78% of the participants spent daily at least 2 hours, 40% more than 4 hours online. Using factor analysis, four factors of online activities were identified: Social networking-surfing, News-information, Risky and Lonely game factors. Only the News-information factor was not related to the problematic internet use. Based on multiple regression analyses, we may conclude that shyness, stress, loneliness and two factors, the Social networking-surfing and the Risky factors acted as background variables for problematic internet use. As a summary we may conclude that the internet has an important role in the everyday life of the participants. In case of the direct aim of the online activities the problematic use did not appear. These activities were mostly searching for information and news. In introduction of prevention, education about the correct use of the internet may be reasonable as early as possible.

    A portal hemodynamic study was made in 7 consecutive patients with chronic portal-systemic encephalopathy by percutaneous transhepatic catheterization of the portal vein and injecting contrast medium into the superior mesenteric vein or by superior mesenteric arterial portography in comparison with patients without encephalopathy studied by percutaneous catheterization of these veins. It is suggested that chronic portal-systemic encephalopathy is a result of a large collateral route shunting a large proportion of the superior mesenteric venous blood into systemic circulation, and that development of such collaterals precludes formation of large esophageal varices.

    2016-03-01

    Obliterative portal venopathy without portal hypertension has been described by a single study in a limited number of patients, thus very little is known about this clinical condition. This study aimed to investigate the prevalence of obliterative portal venopathy and its clinical-pathological correlations in patients with cryptogenic chronic liver test abnormalities without clinical signs of portal hypertension. We analysed 482 liver biopsies from adults with non-cirrhotic cryptogenic chronic liver disorders and without any clinical signs of portal hypertension, consecutively enrolled in a 5-year period. Twenty cases of idiopathic non-cirrhotic portal hypertension diagnosed in the same period, were included for comparison. Histological findings were matched with clinical and laboratory features. Obliterative portal venopathy was identified in 94 (19.5%) of 482 subjects and in all 20 cases of idiopathic non-cirrhotic portal hypertension: both groups shared the entire spectrum of histological changes described in the latter condition. The prevalence of incomplete fibrous septa and nodular regenerative hyperplasia was higher in the biopsies of idiopathic non-cirrhotic portal hypertension (P = 0.006 and P = 0.002), a possible hint of a more advanced stage of the disease. The two groups also shared several clinical laboratory features, including a similar liver function test profile, concomitant prothrombotic conditions and extrahepatic autoimmune disorders. Obliterative portal venopathy occurs in a substantial proportion of patients with unexplained chronic abnormal liver function tests without portal hypertension. The clinical-pathological profile of these subjects suggests that they may be in an early (non-symptomatic) stage of idiopathic non-cirrhotic portal hypertension. © 2015 John Wiley & Sons A/S.

    Hesdorffer, C.S.; Bezwoda, W.R.; Danilewitz, M.D.; Esser, J.D.; Tobias, M.

    1987-01-01

    The use of a simple, noninvasive, isotope scanning technique for the determination of relative portal blood flow and detection of portal hypertension is described. Using this technique the presence of portal hypertension was demonstrated in seven of nine patients known to have elevated portal venous pressure. By contrast, esophageal varices were demonstrated in only five of these patients, illustrating the potential value of the method. Furthermore, this technique has been adapted to the study of portal blood flow in patients with myeloproliferative disorders with splenomegaly but without disturbances in hepatic architecture. Results demonstrate that the high relative splenic flow resulting from the presence of splenomegaly may in turn be associated with elevated relative portal blood flow and portal hypertension. The theoretic reasons for the development of flow-related portal hypertension and its relationship to splenic blood flow are discussed

    Objective: To analyze CT portal venography (CTPV) manifestations of portal collateral circulation in patients with cirrhosis by using a 16-detector row spiral CT scanner. Methods: CTPV was performed in 36 patients with portal hypertension due to cirrhosis, the diagnosis was proved by clinical data, hepatic function findings and imaging signs. By using post-processing reconstruction technique, 3D images of portal venous system and portal collateral circulation were obtained. Results: CTPV images displayed the portal venous system and its collateral circulation stereoscopically. Of 36 patients, left gastric varices were seen in 29(80.6%), lower esophageal varices in 18(50.0%), short gastric or posterior gastric varices in 15(41.7%), paraesophageal varices in 9(25.0%), gastro-renal or splenorenal shunts in 8(22.2%), spongelike transformation of portal vein in 7(19.4%), paraumbilical and abdominal wall varices in 6(16.7%), congenital cavernous in 6(16.7%) and paravertebral venous shunts in 4(11.1%). Conclusion: CTPV can well display the site, extent and severity of the portal collateral circulation in patients with portal hypertension due to cirrhosis,which is of great clinical importance for judging the patient's condition, for selecting therapeutic protocols and for estimating prognosis.

    Full text: We present in this paper a new concept of gamma radiation portal detector, where the detection process is monitored by a micro-controller, coupled to a compatible GSM communication system, which is suitable to be accessed by all mobile phone operators worldwide. The signal generated at the detectors is converted by an A/D circuit, and driven to a micro-controller where a software evaluates the signal conditions and, depending on a previously set program, it triggers a communication system which sends the alarm to any computer linked to internet and/or to any mobile phone protocol by a specific software linked to the portal. The control electronic system is compatible to several detectors types, ranging from gas based devices to solid state ones. The portal is totally compatible with the ANSI - Standard N42.35 - 2004. It can be used in all types of government and industrial control scenarios. Its measure device permits the use of the equipment in all range of sensibility and in tracking radiation signals where it is. (author)

  10. Generating news media interest in tobacco control; challenges in an advanced policy environment.

    MacKenzie, Ross; Chapman, Simon

    2012-08-01

    To determine the efficacy of using media releases for tobacco control advocacy in Australia's advanced policy environment. Between February and August 2010, news releases that summarised either newly published but unpublicized research findings, or local developments in tobacco control, were sent to NSW media outlets. Reports arising from the releases were tracked using commercial services Media Monitors and Factiva, as well as Google and Google News. Other tobacco control related news items during the same period were also tracked and recorded. Twenty-one news releases generated 93 news items across all news media, with a quarter of these related to a story of porcine haemoglobin in cigarette filters. By comparison, 'live' policy issues (especially plain packaging and a significant tobacco tax increase) covered in this period attracted 1,033 news stories in the Australian media. Press releases describing recently published, but underpublicized research were issued in weeks where no major competing tobacco control news occurred. Results of this project indicate that in environments with advanced tobacco policy, media opportunities related to tobacco control advocacy are limited, as many objectives have been achieved. The media can still play a key advocacy role in such environments, and advocates need to be particularly vigilant for opportunities that do arise. The paper also highlights the increasingly important role of internet-based media, including opportunities presented by social media for tobacco control.

    The Gulf of Mexico Coastal Ocean Observing System's (GCOOS) regional science portal (gcoos.org) was designed to aggregate data and model output from distributed providers and to offer these, and derived products, through a single access point in standardized ways to a diverse set of users. The portal evolved under the NOAA-led U.S. Integrated Ocean Observing System (IOOS) program where automated largely-unattended machine-to-machine interoperability has always been a guiding tenet for system design. The web portal has a business unit where membership lists, new items, and reference materials are kept, a data portal where near real-time and historical data are held and served, and a products portal where data are fused into products tailored for specific or general stakeholder groups. The staff includes a system architect who built and maintains the data portal, a GIS expert who built and maintains the current product portal, the executive director who marshals resources to keep news items fresh and data manger who manages most of this. The business portal is built using WordPress which was selected because it appeared to be the easiest content management system for non-web programmers to add content to, maintain and enhance. The data portal is custom built and uses database, PHP, and web services based on Open Geospatial Consortium standards-based Sensor Observation Service (SOS) with Observations and Measurements (O&M) encodings. We employ a standards-based vocabulary, which we helped develop, which is registered at the Marine Metadata Interoperability Ontology Registry and Repository (http://mmisw.org). The registry is currently maintained by one of the authors. Products appearing in the products portal are primarily constructed using ESRI software by a Ph.D. level Geographer. Some products were built with other software, generally by graduate students over the years. We have been sensitive to the private sector when deciding which products to produce. While

  13. OntoFire: an ontology-based geo-portal for wildfires

    2011-12-01

    With the proliferation of the geospatial technologies on the Internet, the role of geo-portals (i.e. gateways to Spatial Data Infrastructures) in the area of wildfires management emerges. However, keyword-based techniques often frustrate users when looking for data of interest in geo-portal environments, while little attention has been paid to shift from the conventional keyword-based to navigation-based mechanisms. The presented OntoFire system is an ontology-based geo-portal about wildfires. Through the proposed navigation mechanisms, the relationships between the data can be discovered, which would otherwise not be possible when using conventional querying techniques alone. End users can use the browsing interface to find resources of interest by using the navigation mechanisms provided. Data providers can use the publishing interface to submit new metadata, modify metadata or removing metadata in/from the catalogue. The proposed approach can improve the discovery of valuable information that is necessary to set priorities for disaster mitigation and prevention strategies. OntoFire aspires to be a focal point of integration and management of a very large amount of information, contributing in this way to the dissemination of knowledge and to the preparedness of the operational stakeholders.

    Chiu, Alice P. Y.; Lin, Qianying

    2017-01-01

    Background The HIV epidemic in Hong Kong has worsened in recent years, with major contributions from high-risk subgroup of men who have sex with men (MSM). Internet use is prevalent among the majority of the local population, where they sought health information online. This study examines the impacts of HIV/AIDS and MSM news coverage on web search query in Hong Kong. Methods Relevant news coverage about HIV/AIDS and MSM from January 1st, 2004 to December 31st, 2014 was obtained from the WiseNews databse. News trends were created by computing the number of relevant articles by type, topic, place of origin and sub-populations. We then obtained relevant search volumes from Google and analysed causality between news trends and Google Trends using Granger Causality test and orthogonal impulse function. Results We found that editorial news has an impact on “HIV” Google searches on HIV, with the search term popularity peaking at an average of two weeks after the news are published. Similarly, editorial news has an impact on the frequency of “AIDS” searches two weeks after. MSM-related news trends have a more fluctuating impact on “MSM” Google searches, although the time lag varies anywhere from one week later to ten weeks later. Conclusions This infodemiological study shows that there is a positive impact of news trends on the online search behavior of HIV/AIDS or MSM-related issues for up to ten weeks after. Health promotional professionals could make use of this brief time window to tailor the timing of HIV awareness campaigns and public health interventions to maximise its reach and effectiveness.

    People dislike giving bad news, and one strategy they use to ease the process is to pair bad news with some good news, a phenomenon called blended news delivery. Often, blended news arrives from people in power positions such as physicians, managers, or teachers. But followers also find themselves needing to give bad news to those in higher power positions. Similarly, people can choose how they deliver bad news, such as in person or over email. The current study brings much needed empirical a...

    Full Text Available Little is known about the views of young patients themselves on interactive Web portal services provided by pediatric practitioners. We aimed to explore their perceptions of a real-world diabetes portal that offers facts and contact with peers and practitioners; e.g., discussion forums, blog tools, self-care and treatment information, research updates and news from local practitioners. Twelve young patients (ages 12–21, median 15 years, one boyfriend, 7 mothers and one father each wrote an essay on their experience from use of the portal. Their essays underwent qualitative content analysis. A major theme was “Helping and facilitating daily life with diabetes”, the portal was perceived as a place where contents are interesting, inspiring and may trigger users’ curiosity. There were three subthemes; “Ease of use in my everyday life,” which includes the perception that the portal was perceived as smooth and easy to enter and navigate whenever needed; that information was easy to understand for different groups of users. “Support via an exchange of experience,” includes the ability to contact peers being regarded advantageous. Some said that just reading others’ experiences can be helpful in terms of persevering; children could find peers in the same age group. “Evidence based information,” includes the perception of the portal being a useful and trustworthy source of facts on e.g., physical activity, blood glucose, medical devices, emotional wellbeing, food and nutrition, and other aspects that impact living with diabetes. Young users expressed positive perceptions towards the interactive web portal. Such services seem to have great potential for supporting young patients and significant others - intergrading for confidence.

    I'm retired and living back home in Austria. But I am still excited about ATLAS and I try to follow the progress of the project as closely as I can. The ATLAS e-news are an excellent source of information. Appearing now every month they provide a broad, solid view of what is going on. But I'm greedy; I'd love to be "on-line". When the first End-Cap Toroid moved from hall 180 to the pit I was frustrated. I knew that it was happening but I could only get first pictures and reports a few days later. In the meantime the ECT was lowered into the cavern; no information on this available nowhere up to the this issue of the e-news. Here is my dream: an "ATLAS news ticker", i.e. a web page with the news appearing on the day they happen; just one line of information, possibly with a reference to a picture, a person or a report. My idea isn't new. On the ATLAS web-site for the public we have a window "latest news". But I was disappointed when, until a week ago, the latest news dated from December 2006 !!! Can't we do...

    Sander, U; Emmert, M; Grobe, T G

    2013-06-01

    The Internet provides ways for patients to obtain information about doctors. The study poses the question whether it is possible and how long it takes to find a suitable doctor with an Internet search. It focuses on the effectiveness and efficiency of the search. Specialised physician rating and searching portals and Google are analysed when used to solve specific tasks. The behaviour of volunteers when searching a suitable ophthalmologist, dermatologist or dentist was observed in a usability lab. Additionally, interviews were carried out by means of structured questionnaires to measure the satisfaction of the users with the search and their results. Three physician rating and searching portals that are frequently used in Germany (Jameda.de, DocInsider.de and Arztauskunft.de) were analysed as well as Google. When using Arztauskunft and Google most users found an appropriate physician. When using Docinsider or Jameda they found fewer doctors. Additionally, the time needed to locate a suitable doctor when using Docinsider and Jameda was higher compared to the time needed when using the Arztauskunft and Google. The satisfaction of users who used Google was significantly higher in comparison to those who used the specialised physician rating and searching portals. It emerged from this study that there is no added value when using specialised physician rating and searching portals compared to using the search engine Google when trying to find a doctor having a particular specialty. The usage of several searching portals is recommended to identify as many suitable doctors as possible. © Georg Thieme Verlag KG Stuttgart · New York.

  1. Corporate portal system at PAKS NPP, Hungary

    International Nuclear Information System (INIS)

    2009-01-01

    The new Corporate Portal System (CPS) of Paks NPP was launched in November 2006. The portal is based on one of the latest technologies, Plumtree Enterprise WEB 5.0. The main purpose of the installation of the new technology was to serve the working culture change, to give a platform to access all information and applications including the integrated process model used at the NPP. The new technology also supports those goals which were defined in the organization development programme: e.g. to improve internal communication with the establishment of communities of practice. Installation of the CPS has provided a powerful tool for knowledge management; it is possible to share and find all information through a controlled access in documents from various sources, to have links to people, portlets and different communities. Document management of the Paks NPP is supported by the integration of the Document 5 application, as the new Electronic Data Management System (EDMS) and the CPS. Depending on their access rights, all users of the CPS, through Microsoft Internet Explorer, can access technical, economic and human resources documents which are stored anywhere on the internal network (file servers, EDMS, old INRANET). The CPS is also accessible from the internet through a secure connection. The main concept is the integration of all applications to one platform and to help users to find all information they need. An access control list specifies which users and groups have access to an object (and what kind of access privileges they have such as read, select, edit, admin)

    2012-02-01

    Full Text Available This article focuses on user experiences on reading location-aware news on the mobile platform and aims to explore what experiences this kind of locative journalism generates and how such experiences change the users’ social interaction with news. We produced a specially designed mobile application and tailored news stories specific to this project called LocaNews in order to explore participants’ relation to the content in this journalistic format. The result is generated through a field study and a questionnaire of 32 people to find out how they experience the news presented in this format. The user participants’ responses are analyzed based on their news experiences, contextualizing places and their social interaction with the news within this form of journalism. Results showed that the local, semi-local and non-local user approaches the locative news in a different manner, but that the average user found this kind of news more interesting and more informative than ordinary news. The participants also have a problem identifying this as journalism, rather than an information service.

    People are increasingly interested in health news. As a mass media, the 'Islamic Republic of Iran Broadcasting' (IRIB) has the highest number of target audiences. In Iran, some people follow health news via health programs on satellites and other means of communication. However, all of these programs do not live up to the standards of scientific evidence. In this study, we examined Tehran people's trust in health news disseminated by the IRIB and other mass media outlets. A cross-sectional study was conducted in Tehran. Through multistage sampling, 510 households proportional to size were randomly selected from five regions of Tehran including northern, eastern, western, southern and central regions. One person from each household completed the questionnaire through interviews. The questionnaire included questions on people's level of trust in health news delivered by the IRIB, satellite programs, the internet and magazines. It also included demographic questions. The validity and reliability of the questionnaire was evaluated. Among the interviewees, 50.6% was female. The highest level of trust by the participants was observed in the IRIB (65.2%), and the lowest trust was observed in satellite news (43.4%); pnews broadcasters had more mastery over the subject than the ones in satellite channels (pnews (pnews had improved in the past 10 years. Fifty nine point eight percent of participants believed the quality and accuracy of the IRIB health news was monitored. People's higher level of trust in domestic news as compared to foreign sources and the better status of domestic sources in other areas such as precision in reporting, coverage of more important news, its delivery in lay language, the news broadcasters' proficiency, and other cases - from the participants' point of view - can highlight the significance of designing interventions for changing health behavior among domestic health news producers. Therefore, the results of this study can prove useful to health

    Full Text Available Nowadays, systematic reforms are realized acrossmany countries. One of the characteristics of these reforms is necessity for rationalization of expenses in governmental and public enterprises. Rationalization of expenses can be achieved by more extensive application of information and communication technologies based on internet technologies and cloud computing. These systems include huge number of services, applications, resources, users and roles. At the same time, concepts of scalability, availability, ubiquity and pervasiveness need to be applied. This paper deals with application of portal technologies for enhanced content management, document management, and collaboration within public enterprises. The goal is to achieve efficient exchange of information on all hierarchical levels, as well as mechanisms of reporting and performance measurements, such as business intelligence and key performance indicators. The model is based on SharePoint portal technologies. A case study of application within the public enterprise Post of Serbia is described.

    The spread of invasive alien plants has considerable environmental and economic consequences, and is one of the most challenging ecological problems. The spread of invasive alien plant species depends largely on long-distance dispersal, which is typically linked with human activity. The increasing domination of the internet will have impacts upon almost all components of our lives, including potential consequences for the spread of invasive species. To determine whether the rise of Internet commerce has any consequences for the spread of invasive alien plant species, we studied the sale of thirteen of some of the most harmful Europe invasive alien plant species sold as decorative plants from twenty-eight large, well known gardening shops in Poland that sold both via the Internet and through traditional customer sales. We also analyzed temporal changes in the number of invasive plants sold in the largest Polish internet auction portal. When sold through the Internet invasive alien plant species were transported considerably longer distances than for traditional sales. For internet sales, seeds of invasive alien plant species were transported further than were live plants saplings; this was not the case for traditional sales. Also, with e-commerce the shape of distance distribution were flattened with low skewness comparing with traditional sale where the distributions were peaked and right-skewed. Thus, e-commerce created novel modes of long-distance dispersal, while traditional sale resembled more natural dispersal modes. Moreover, analysis of sale in the biggest Polish internet auction portal showed that the number of alien specimens sold via the internet has increased markedly over recent years. Therefore internet commerce is likely to increase the rate at which ecological communities become homogenized and increase spread of invasive species by increasing the rate of long distance dispersal.

    2016-05-01

    Full Text Available Alternatives to the dominant public sphere and associated dialogue are especially important for underrepresented groups. These alternatives allow for groups to create their own dialogues that can then be used to change the direction of the larger discussion. While the Internet seems to be the perfect tool for these alternative dialogues to be created, the feasibility of using the Internet to take the next step into mainstream dialogue remains unclear. The black blogosphere is one alternative information stream pushing back. This chapter examines the way in which the black blogosphere discusses news stories and offers alternatives to the mainstream discourse, and why it is crucial that these alternative public spheres are available.

  20. A qualitative study of the coverage of influenza vaccination on Dutch news sites and social media websites.

    2013-06-05

    Information about influenza and the effectiveness of vaccination against influenza is largely available on the Internet, and may influence individual decision making about participation in future influenza vaccination rounds. E-health information has often been found to be inaccurate, or even to contradict Health Authority recommendations, especially when it concerns controversial topics. By means of an online media monitoring programme, Dutch news sites and social media websites were scanned for the Dutch counterparts of the terms influenza, vaccination, vaccine and epidemic during February, March and April 2012. Data were processed with QSR NVivo 8.0 and analysed using a general inductive approach. Three overarching themes were found in both media sources: (1) the (upcoming) influenza epidemic, (2) general information regarding the virus, its prevention and treatment, and (3) uncertainty and mistrust regarding influenza vaccination. Social media tended to report earlier on developments such as the occurrence of an influenza epidemic. The greatest difference was that in social media, influenza was not considered to be a serious disease, and more opposition to the flu shot was expressed in social media, as compared to news media. News media and social media discussed the same topics regarding influenza, but differed in message tone. Whereas news media reports tended to be more objective and non-judgmental, social media more critically evaluated the harmfulness of influenza and the necessity of the flu shot. Media may influence decision making and behaviours of Internet users and may thereby influence the success of vaccination campaigns and recommendations made by health authorities. Social media may be more of a problem in this sense, since it is neither controlled nor censored. Future research should investigate the actual impact of Internet media on the influenza decision making process of its users.

  6. Problematic internet use in childhood and youth: evolution of a 21st century affliction.

    Science.gov (United States)

    Tam, Philip; Walter, Garry

    2013-12-01

    To describe the emergence of, and myriad issues pertaining to, problematic internet use in childhood and youth. In this overview and appraisal of a uniquely 21st century affliction, the focus is on youth and less on young adult perspectives. We employed relevant literature-search methodology though EMBASE, Psychinfo and Web of Science, utilising the key terms of PIU, internet addiction and youth mental health, and present a selection of the pioneering and important research developments both nationally and internationally. We focused on the literature from the past 10 years, but we also included relevant early developments in the field going back to the 1990s. We also made reference, where appropriate, to major considerations of relevance to the general public, where these were reported in reputable international news and media organisations. The authors utilised common internet search engines to access these news reports. It was found that the complex, novel and at times controversial concept of 'problematic internet use' (PIU)--often popularly dubbed 'internet addiction'--has attracted much public, media and research interest, particularly over the past decade. In common with many other afflictions that have a prominent 'pop-cultural' component, often the commentary and debate has been polarising, unclear and sensationalist. At times, more light than heat appears to be generated.

  9. eBooking of beam-time over internet for beamlines of Indus synchrotron radiation sources

    International Nuclear Information System (INIS)

    Jain, Alok; Verma, Rajesh; Rajan, Alpana; Modi, M.H.; Rawat, Anil

    2015-01-01

    Users from various research labs and academic institutes carry out experiments on beamlines of two Synchrotron Radiation Sources Indus-1 and Indus-2 available at RRCAT, Indore. To carry out experimental work on beamlines of both synchrotron radiation sources, beam-time is booked over Internet by the users of beamlines using user portal designed, developed and deployed over Internet. This portal has made the process of beamtime booking fast, hassle free and paperless as manual booking of beam-time for carrying out experiment on a particular beamline is cumbersome. The portal facilitates in-charge of Indus-1 and Indus-2 beamlines to keep track of users' records, work progress and other activities linked to experiments carried on beamlines. It is important to keep record and provide statistics about the usage of the beam lines from time-to-time. The user portal for e-booking of beam-time has been developed in-house using open source software development tools. Multi-step activities of users and beamline administrators are workflow based with seamless flow of information across various modules and fully authenticated using role based mechanism for different roles of software usage. The software is in regular use since November 2013 and has helped beamline in- charges in efficiently managing various activities related to user registration, booking of beam-time, booking of Guest House, Generation of Security permits, User feedback etc. Design concept, role based authentication mechanism and features provided by the web portal are discussed in detail in this paper.

    Objective: To evaluate the value of endovascular stent in the treatment of portal hypertension caused by benign main portal vein stenosis. Methods: Portal vein stents were implanted in 6 patients with benign main portal vein stenosis (inflammatory stenosis in 3 cases, postprocedure of liver transplantation in another 3 cases). The change of portal vein pressure, the patency of portal vein, relative clinical symptoms, complications, and survival were evaluated. Results: Six metallic stents were successfully placed across the portal vein stenotic or obstructive lesions in all 6 patients. Mean portal venous pressure decreased significantly after stent implantation from (37.3 ± 4.7) cm H 2 O (1 cm H 2 O=0.098 kPa) to (18.0 ± 1.9) cm H 2 O (P<0.001). The portal blood flow was restored, and the symptoms caused by portal hypertension were eliminated. There was no severe procedure-related complication. Follow-up time was from 5 to 36 months. The portal vein remained patent during the follow-up. All patients survived except one patient who died of other complications of liver transplantation. Conclusion: Percutaneous portal vein stent placement for the treatment of the benign main portal vein stenosis is safe and effective. (authors)

    Da, Ben L; Koh, Christopher; Heller, Theo

    2018-05-01

    Noncirrhotic portal hypertension represents a heterogeneous group of liver disorders that is characterized by portal hypertension in the absence of cirrhosis. The purpose of this review is to serve as a guide on how to approach a patient with noncirrhotic portal hypertension with a focus on recent developments. Recent studies pertaining to noncirrhotic portal hypertension have investigated aetiological causes, mechanisms of disease, noninvasive diagnostic modalities, clinical characteristics in the paediatric population and novel treatment targets. Noncirrhotic portal hypertension is an underappreciated clinical entity that can be difficult to diagnosis without a healthy suspicion. Diagnosis then relies on a comprehensive understanding of the causes and clinical manifestations of this disease, as well as a careful interpretation of the liver biopsy. Noninvasive approaches to diagnosis may play a significant role moving forward in this disease. Treatment in NCPH remains largely targeted at the individual sequalae of portal hypertension.

    2002-01-01

    Objective: To find out the ideal portal vein tar getting injection routes for portal hypertension treatment. Methods: 28 cirrhotic rat models with portal hypertension induced by CCl 4 were divided into 4 groups: inferior caval vein injection group, portal vein injection group, hepatic artery injection group, spleen injection group. The changes in portal vein pressure (PVP), inferior caval vein pressure (ICVP), mean artery pressure (MAP) and heart rate (HR) were monitored before and after prazosin injection. Results: After intra-portal, intra-hepatic arterial or spleen injection of prazosin, larger decrease in PVP and lesser effects on MAP than intravenous injection had been induced. The effect on HR showed no difference among these four groups. Conclusions: Hepatic artery and spleen prazosin administration have the same advantages on treatment of portal hypertension as those of intra-portal infusion, that is the greater decrease on portal vein pressure, the lesser effects on systemic hemodynamics. Vasodilation drugs for hepatic artery infusion through percutaneous port catheter system by hepatic artery implantation would be an ideal method for portal hypertension treatment

    The use of a Web portal for patients with diabetes mellitus to access their own personal health record may result in improved diabetes outcomes. However, the adoption by patients is slow. This may be caused by patient characteristics, but also by the content, layout, and promotion of the portal. Detailed knowledge about this could help increase patients' participation in Web portals. The aim was to study the opinions of patients with diabetes and identify perceived barriers to using a Web portal to optimize its use. We conducted a survey among patients with type 1 and type 2 diabetes mellitus from 62 primary care practices and 1 outpatient hospital clinic in the central area of the Netherlands who all used the same electronic health record with a Web portal. Questionnaires about patient characteristics, opinions about reasons for use or nonuse, and about portal content were sent to 1500 patients with a login and 3000 patients without a login to the Web portal. Patient groups were stratified according to login frequency. Demographic and diabetes-related variables were analyzed with multivariable regression analysis. The total response rate was 66.63% (2391/4399); 1390 of 4399 patients (31.60%) were eligible for analysis. There were 413 regular users (login frequency more than once) and 758 nonusers (no login). Most nonusers (72.4%) stated that the main reason for not requesting a login was that they were unaware of the existence of the portal. Other barriers reported by patients were disinterest in managing their own disease (28.5%, 216/758) and feelings of inadequacy with the use of computers and Internet (11.6%, 88/758). Patients treated by a general practitioner were more frequently nonusers compared to patients treated by an internist (78.8%, 666/846 vs 28.3%, 92/325; Ppatient portal is the main barrier of enrollment. Users and nonusers perceive the usefulness of the portal differently and do not have the same recommendations for additional functionalities. To

  18. Portal vein thrombosis.

    Science.gov (United States)

    Chawla, Yogesh K; Bodh, Vijay

    2015-03-01

    Portal vein thrombosis is an important cause of portal hypertension. PVT occurs in association with cirrhosis or as a result of malignant invasion by hepatocellular carcinoma or even in the absence of associated liver disease. With the current research into its genesis, majority now have an underlying prothrombotic state detectable. Endothelial activation and stagnant portal blood flow also contribute to formation of the thrombus. Acute non-cirrhotic PVT, chronic PVT (EHPVO), and portal vein thrombosis in cirrhosis are the three main variants of portal vein thrombosis with varying etiological factors and variability in presentation and management. Procoagulant state should be actively investigated. Anticoagulation is the mainstay of therapy for acute non-cirrhotic PVT, with supporting evidence for its use in cirrhotic population as well. Chronic PVT (EHPVO) on the other hand requires the management of portal hypertension as such and with role for anticoagulation in the setting of underlying prothrombotic state, however data is awaited in those with no underlying prothrombotic states. TIPS and liver transplant may be feasible even in the setting of PVT however proper selection of candidates and type of surgery is warranted. Thrombolysis and thrombectomy have some role. TARE is a new modality for management of HCC with portal vein invasion.

    Full Text Available The present study aimed to compare discursive strategies employed by two international news agencies including Euro News and BBC. Van Dijk’s (2004 model of CDA was adopted. Thirty pieces of news about internal affairs of Iran together with their Persian translations were downloaded from the corresponding website, i.e. 30 pieces of English news and their corresponding Persian translations from the Euro News website and 30 pieces of English news with their corresponding translations from the BBC website. The frequency of lexical items was observed to not differ significantly. Two sets of translations were compared to their source texts based on four discursive strategies of hyperbole, polarization, vagueness and euphemism. An independent-samples t-test was conducted to compare the frequency of strategies applied by the two news agencies. Results revealed no significant difference between the two agencies except for the discursive strategy of vagueness.

    2006-01-01

    In 2001, the Health Promotion Board (HPB) developed HPB Online, an internet-based health education portal to disseminate health messages. The objective of this article is to describe the structure of HPB Online, review its reach as a tool to deliver health information in Singapore, and discuss the advantages of using the internet to complement traditional media such as the television, newspapers and radio. Since its inception in 2001, the numbers of page-views, monthly visits and repeat visitors have increased markedly. The most popular webpages have consistently been Food Info Search. The average length of visit also showed a gradual increase during the study period, from about 11.0 minutes in January 2002 to 18.5 minutes in December 2004. The key advantage of using the HPB Online is that it allows quick delivery of information to the public and this is ideal for time-sensitive issues. It helps Singaporeans to make better informed decisions to maintain and to improve their health. With its high utilisation, the HPB will continue to use the internet as part of its multichannel marketing strategy to disseminate health information.

    There are few data available on how physicians inform patients about bad news. We surveyed internists about how they convey this information. We surveyed internists about their activities in giving bad news to patients. One set of questions was about activities for the emotional support of the patient (11 items), and the other was about activities for creating a supportive environment for delivering bad news (9 items). The impact of demographic factors on the performance of emotionally supportive items, environmentally supportive items, and on the number of minutes reportedly spent delivering news was analyzed by analysis of variance and multiple regression analysis. More than half of the internists reported that they always or frequently performed 10 of the 11 emotionally supportive items and 6 of the 9 environmentally supportive items while giving bad news to patients. The average time reportedly spent in giving bad news was 27 minutes. Although training in giving bad news had a significant impact on the number of emotionally supportive items reported (P woman, unmarried, and having a history of major illness were also associated with reporting a greater number of emotionally supportive activities. Internists report that they inform patients of bad news appropriately. Some deficiencies exist, specifically in discussing prognosis and referral of patients to support groups. Physician educational efforts should include discussion of prognosis with patients as well as the availability of support groups.

    2018-03-05

    Public media reports about suicide are likely to influence the population's suicidal attempts and completed suicides. Irresponsible reports might trigger copycat suicidal behaviors, while responsible reports may help reduce suicide rates. The World Health Organization (WHO) released recommendations to encourage responsible suicide reports in 2008. However, little is known about whether these recommendations are reflected in the suicide news for most countries, including China. In this study, we assessed the responsibility of suicide stories published in the most influential newspaper and Internet media sources in China from 2003 to 2015, using the media reporting recommendations by the World Health Organization (WHO). In total, 3965 and 1836 eligible stories from newspaper and Internet-based media, respectively, were included in the study. Newspapers and Internet-based media performed similarly in applying WHO recommendations to report suicide news. Three recommendations were applied in over 88% of suicide stories. However, four recommendations were seldom applied, including offering information about where to seek help and linking the suicide event to mental disorders. Government and the journalism industry should work together to improve media reporting of news about suicide in China.

  5. Hepatic angiography: Portal hypertension

    International Nuclear Information System (INIS)

    Oliver, T.W. Jr.; Sones, P.J. Jr.

    1985-01-01

    Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

    Dobbins, Maureen; Haynes, R. Brian; Iorio, Alfonso; Lavis, John N; Raina, Parminder

    2016-01-01

    Background Increasingly, older adults and their informal caregivers are using the Internet to search for health-related information. There is a proliferation of health information online, but the quality of this information varies, often based on exaggerated or dramatic findings, and not easily comprehended by consumers. The McMaster Optimal Aging Portal (Portal) was developed to provide Internet users with high-quality evidence about aging and address some of these current limitations of health information posted online. The Portal includes content for health professionals coming from three best-in-class resources (MacPLUS, Health Evidence, and Health Systems Evidence) and four types of content specifically prepared for the general public (Evidence Summaries, Web Resource Ratings, Blog Posts, and Twitter messages). Objective Our objectives were to share the findings of the usability evaluation of the Portal with particular focus on the content features for the general public and to inform designers of health information websites and online resources for older adults about key usability themes. Methods Data analysis included task performance during usability testing and qualitative content analyses of both the usability sessions and interviews to identify core themes. Results A total of 37 participants took part in 33 usability testing sessions and 21 focused interviews. Qualitative analysis revealed common themes regarding the Portal’s strengths and challenges to usability. The strengths of the website were related to credibility, applicability, browsing function, design, and accessibility. The usability challenges included reluctance to register, process of registering, searching, terminology, and technical features. Conclusions The study reinforced the importance of including end users during the development of this unique, dynamic, evidence-based health information website. The feedback was applied to iteratively improve website usability. Our findings can be

    Gougousis, Alexandros; Bailly, Nicolas

    2016-01-01

    Biodiversity data is characterized by its cross-disciplinary character, the extremely broad range of data types and structures, and the plethora of different data sources providing resources for the same piece of information in a heterogeneous way. Since the web inception two decades ago, there are multiple initiatives to connect, aggregate, share, and publish biodiversity data, and to establish data and work flows in order to analyze them. The European program LifeWatch aims at establishing a distributed network of nodes implementing virtual research environment in Europe to facilitate the work of biodiversity researchers and managers. LifeWatchGreece is one of these nodes where a portal was developed offering access to a suite of virtual laboratories and e-services. Despite its strict definition in information technology, in practice "portal" is a fairly broad term that embraces many web architectures. In the biodiversity domain, the term "portal" is usually used to indicate either a web site that provides access to a single or an aggregation of data repositories (like: http://indiabiodiversity.org/, http://www.mountainbiodiversity.org/, http://data.freshwaterbiodiversity.eu), a web site that gathers information about various online biodiversity tools (like http://test-eubon.ebd.csic.es/, http://marine.lifewatch.eu/) or a web site that just gathers information and news about the biodiversity domain (like http://chm.moew.government.bg). LifeWatchGreece's portal takes the concept of a portal a step further. In strict IT terms, LifeWatchGreece's portal is partly a portal, partly a platform and partly an aggregator. It includes a number of biodiversity-related web tools integrated into a centrally-controlled software ecosystem. This ecosystem includes subsystems for access control, traffic monitoring, user notifications and web tool management. These subsystems are shared to all the web tools that have been integrated to the portal and thereby are part of this

    Full Text Available Public media reports about suicide are likely to influence the population’s suicidal attempts and completed suicides. Irresponsible reports might trigger copycat suicidal behaviors, while responsible reports may help reduce suicide rates. The World Health Organization (WHO released recommendations to encourage responsible suicide reports in 2008. However, little is known about whether these recommendations are reflected in the suicide news for most countries, including China. In this study, we assessed the responsibility of suicide stories published in the most influential newspaper and Internet media sources in China from 2003 to 2015, using the media reporting recommendations by the World Health Organization (WHO. In total, 3965 and 1836 eligible stories from newspaper and Internet-based media, respectively, were included in the study. Newspapers and Internet-based media performed similarly in applying WHO recommendations to report suicide news. Three recommendations were applied in over 88% of suicide stories. However, four recommendations were seldom applied, including offering information about where to seek help and linking the suicide event to mental disorders. Government and the journalism industry should work together to improve media reporting of news about suicide in China.

    Full Text Available The aim of the study: To determine the necessary shunt diameter and assess the optimal portal blood volume in a shunt in children with extrahepatic portal hypertension before the portosystemic shunt surgery. Changes in the liver hemodynamics were studied in 81 children aged from 4 to 7 years with extrahepatic portal hypertension. We established that it is necessary to calculate the shunt diameter and the blood volume in a shunt in patients with extrahepatic portal hypertension before the portosystemic shunt surgery. It allows us to preserve the hepatic portal blood flow and effectively decrease the pressure in the portal system. Portosystemic shunt surgery in patients with extrahepatic portal hypertension performed in accordance with the individualized shunt volume significantly decreases portal pressure, preserves stable hepatic hemodynamics and prevents gastro-esophageal hemorrhage.

    To describe the CT findings of portal vein aneurysm in eight patients. All patients included in this study (two men and six women) underwent CT examinations between October 1996 and June1998. Of these eight, three were suffering from hepatic disease and portal hypertension. We determined the location, shape, size, and characteristics of the lesions, and the presence or absence of portal vein anomaly. Seven patients had intrahepatic portal vein aneurysm (at the umbilical portion of the left portal vein in five patients, between the transverse and umbilical portion of the left portal vein in one, and at the bifurcation of the anterior and posterior branch of the right portal vein in one), while extrahepatic portal vein aneurysm, at the confluence of the superior mesenteric and splenic vein was found in only one. Lesions were cyst-shaped in seven cases and saccular in one, and showed well-circumscribed, markedly enhanced mass, which communicated with the portal vein and/or gives off major branches. Portal vein anomaly, in which the right anterior segmental portal vein originated from the umbilical portion of the left portal vein, was seen in three patients. In all three, intrahepatic portal vein aneurysm was present at the umbilical portion of the left portal vein, and in one, the umbilical protion of the left portal vein was located to the right of the Cantlic line. CT examination can help reveal portal vein aneurysm by detecting a well-circumscribed, markedly enhanced mass which communicates with the portal vein and/or gives off major branches

    Internet-based technologies such as personal health records and patient portals are increasingly viewed as essential for enhancing patient-provider communication and patient-centered care. We examined how primary care patients use the Internet, particularly patient characteristics associated with Internet use. We surveyed patients in five primary care clinic waiting rooms. Patients who had used email or the Internet in the past month (Internet users) were asked how often they used a computer for a variety of tasks. Participants who reported not using the Internet were asked about several potential barriers to Internet use. We approached 713 patients, and 638 (89.6%) completed questionnaires; 499 (78%) were Internet users and 139 (22%) were non-users. Lack of computer access and not knowing how to use email or the Internet were the most common barriers to Internet use. Younger age, higher education and income, better health, and absence of a chronic illness were associated with Internet use. After controlling for age and other variables, chronic illness was no longer associated with Internet use. Internet use was high among our primary care patients. The major factor associated with Internet use among patients with chronic conditions was their age. If older adults with chronic illness are to reap the benefits of health information technology, their Internet access will need to be improved. Institutions that are planning to offer consumer health information technology should be aware of groups with lower Internet access.

    Given that the public uses the media to learn about adoption as a family form, this study analyzes U.S. television news coverage of adoption between 2001 and 2005 (N = 309 stories), to identify the types of news events covered about adoption. A majority of news stories covered fraud, crime, legal disputes, and negative international adoption cases. Adoptees as defective or unhealthy were depicted more in negative news event stories, birth parents appeared less overall, and adoptive parents were most likely to have healthy depictions in positively oriented adoption experience, big family, and reunion stories. Although three quarters of the stories used primary adoption participants as news sources, one-third of the negative event stories did not contain healthy depictions of adoption participants. The authors discuss ways journalists and researchers might improve adoption news coverage.

    Portal hypertension develops as a result of increased intrahepatic vascular resistance often caused by chronic liver disease that leads to structural distortion by fibrosis, microvascular thrombosis, dysfunction of liver sinusoidal endothelial cells (LSECs), and hepatic stellate cell (HSC) activation. While the basic mechanisms of LSEC and HSC dysregulation have been extensively studied, the role of microvascular thrombosis and platelet function in the pathogenesis of portal hypertension remains to be clearly characterized. As a secondary event, portal hypertension results in splanchnic and systemic arterial vasodilation, leading to the development of a hyperdynamic circulatory syndrome and subsequently to clinically devastating complications including gastroesophageal varices and variceal hemorrhage, hepatic encephalopathy from the formation of portosystemic shunts, ascites, and renal failure due to the hepatorenal syndrome. This review article discusses: (1) mechanisms of sinusoidal portal hypertension, focusing on HSC and LSEC biology, pathological angiogenesis, and the role of microvascular thrombosis and platelets, (2) the mesenteric vasculature in portal hypertension, and (3) future directions for vascular biology research in portal hypertension.

    Four pediatric patients with extrahepatic portal hypertension had undergone portography and computerized radionuclide angiography in order to examine shape of portal system and to evaluate hepatic blood flow before and aftersurgical treatment. In all patients, cavernous transformation of portal system was demonstrated by portography, and in one of them spontaneous splenorenal shunt occurred. In 3 of them, who underwent esophageal transsection combined with paraesophagogastric devascularization and splenectomy, so-called direct operation, increase of portal blood flow was revealed by computerized radionuclide angiography. It is suggested that direct operation increasing portal blood flow after surgery is effective in treating extrahepatic portal hypertension in childhood. (author)

    2008-01-01

    Purpose To quantify the online availability and portrayal of amphetamine-class prescription stimulants with a focus on those medications commonly prescribed to and abused by adolescents. Methods The Google™ search engine was used in searches to assess the frequency of websites offering to sell controlled stimulants (retail sites) or websites that directly linked to retail sites (portal sites). Also, separate searches evaluated the portrayal of controlled prescription stimulants by the initial 20 websites returned by Google™. Retail and portal website frequency was collected for each search. For searches measuring the portrayal of stimulants, webpages were categorized as pro-abuse, anti-abuse, neutral or other, based on set criteria. Results Sites offering to sell stimulants without a prescription were found for nearly all search terms. Across all searches, the Schedule III stimulants indicated for the treatment of obesity returned more sites offering to sell stimulants without a prescription than Schedule II stimulants indicated for the treatment of ADHD. Internet site portrayal of each stimulant varied. However, sites that contained “methamphetamine” often included anti-abuse information. Discussion The apparent availability of stimulants over the Internet without a prescription indicates the potential for a significant public health problem. The extent to which teens are obtaining these drugs via the Internet remains unclear, but clinicians must be aware of the potential for abuse, concomitant prescription use issues, illicit sources, and diversion of these highly addictive medications. Education of consumers and physicians as well as further governmental interventions is needed to limit the potential scope of this problem. PMID:18407040

    To investigate wall shear stress (WSS) magnitude and distribution in cirrhotic patients with portal hypertension using computational fluid dynamics. Idealized portal vein (PV) system models were reconstructed with different angles of the PV-splenic vein (SV) and superior mesenteric vein (SMV)-SV. Patient-specific models were created according to enhanced computed tomography images. WSS was simulated by using a finite-element analyzer, regarding the blood as a Newtonian fluid and the vessel as a rigid wall. Analysis was carried out to compare the WSS in the portal hypertension group with that in healthy controls. For the idealized models, WSS in the portal hypertension group (0-10 dyn/cm 2 ) was significantly lower than that in the healthy controls (10-20 dyn/cm 2 ), and low WSS area (0-1 dyn/cm 2 ) only occurred in the left wall of the PV in the portal hypertension group. Different angles of PV-SV and SMV-SV had different effects on the magnitude and distribution of WSS, and low WSS area often occurred in smaller PV-SV angle and larger SMV-SV angle. In the patient-specific models, WSS in the cirrhotic patients with portal hypertension (10.13 ± 1.34 dyn/cm 2 ) was also significantly lower than that in the healthy controls ( P portal hypertension, the low WSS area extended to wider levels and the magnitude of WSS reached lower levels, thereby being more prone to disturbed flow occurrence. Cirrhotic patients with portal hypertension show dramatic hemodynamic changes with lower WSS and greater potential for disturbed flow, representing a possible causative factor of PV thrombosis.

    1988-01-01

    To determine the reproducibility of splanchnic blood flow measurements by the microsphere method in rats with portal hypertension and the effects of laparotomy with portal vein cannulation, eight groups of 10 rats were studied. Microspheres were labelled with 113 Sn or 141 Ce. Laparotomy with portal cannulation had no significant effect in sham-operated rats. In awake portal hypertensive rats, cardiac output and splanchnic blood flow were lower in portal vein cannulated rats compared with those of non-cannulated animals. In anesthetized portal hypertensive rats blood flows were unaffected by portal cannulation, but arterial pressure and heart rate were elevated. Anesthesia also decreased portal pressure in portal hypertensive rats. We conclude that the microsphere method remains reproducible in portal hypertensive rat models. Laparotomy with portal cannulation can alter systemic and splanchnic hemodynamics in portal hypertensive rats; these effects can also be changed during pentobarbital anesthesia. Regional blood flow measurements in portal hypertensive rats should be performed in animals without portal cannulation and preferably in the awake state

    Full Text Available There are expectations that stem cell therapy (SCT will treat many currently untreatable diseases. The Internet is widely used by patients seeking information about new treatments, and hence, analyzing websites is a representative sample of the information available to the public. Our aim was to understand what information the public would find when searching for information on SCT on Google, as this would inform us on how lay people form their knowledge about SCT. We analyzed the content and information quality of the first 200 websites returned by a Google.com search on SCT. Most websites returned were from treatment centers (TCs, 44% followed by news and medical professional websites. The specialty most mentioned in non-TC websites was “neurological” (67%, followed by “cardiovascular” (42%, while the most frequent indication for which SCT is offered by TCs was musculoskeletal (89% followed by neurological (47%. 45% of the centers specialized in treating 1 specialty, 10% offer 2, and 45% offered between 3 and 18 different specialties. Of the 78 TCs, 65% were in the USA, 23% in Asia, and 8% in Latin America. None of the centers offered SCT based on embryonic cells. Health information quality (JAMA score, measuring trustworthiness was lowest for TCs and commercial websites and highest for scientific journals and health portals. This study shows a disconnection between information about SCT and what is actually offered by TCs. The study also shows that TCs, potentially acting in a regulatory gray area, have a high visibility on the Internet.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    Grid operators in EGEE have been using a dedicated dashboard as their central operational tool, stable and scalable for the last 5 years despite continuous upgrade from specifications by users, monitoring tools or data providers. In EGEE-III, recent regionalisation of operations led the Operations Portal developers to conceive a standalone instance of this tool. We will see how the dashboard reorganization paved the way for the re-engineering of the portal itself. The outcome is an easily deployable package customized with relevant information sources and specific decentralized operational requirements. This package is composed of a generic and scalable data access mechanism, Lavoisier; a renowned php framework for configuration flexibility, Symfony and a MySQL database. VO life cycle and operational information, EGEE broadcast and Downtime notifications are next for the major reorganization until all other key features of the Operations Portal are migrated to the framework. Features specifications will be sketched at the same time to adapt to EGI requirements and to upgrade. Future work on feature regionalisation, on new advanced features or strategy planning will be tracked in EGI- Inspire through the Operations Tools Advisory Group, OTAG, where all users, customers and third parties of the Operations Portal are represented from January 2010.

    Full Text Available Universities of the 21st century are built on digital walls and on the Internet foundation. Their “real virtuality” of M. Castells is represented by information and communication flows that reflect various areas: education, research, culture, leisure, and others. The visual image of a university is the bridge that connects its physical and digital reality and identifies it within the information flow on the Internet. Visual image identification on the Internet and the function that the visual image performs as an electronic communication tool lay the foundation for our research. The key focal point of a university’s visual image on the Internet is its official website. Our research shows that with the development of computer technology, the semantic heterogeneity of universities’ visual images has changed from Web 1.0 to Web 2.0. A university’s web portal both reflects and produces its digital life, which is broader and more informative than the physical life alone, as there are no temporal and spatial boundaries in electronic interactions. Polysemy and directed communication through university’s visual images are effective developments for both online and offline communication for the university. The Internet communication reach all spheres of university life and reflect its content. Visual images of universities, based on electronic communication tools, not only “open” them for digital natives and digital immigrants, but also create a cyberspace for scientific and educational discourse.

    With the advent of transjugular intrahepatic porta-systemic stent shunt and the wider application of the surgically placed small diameter prosthetic H-graft portacaval shunt (HGPCS), partial portal decompression in the treatment of portal hypertension has received increased attention. The clinical results supporting the use of partial portal decompression are its low incidence of variceal rehemorrhage due to decreased portal pressures and its low rate of hepatic failure, possibly due to maintenance of blood flow to the liver. Surprisingly, nothing is known about changes in portal hemodynamics and effective hepatic blood flow following partial portal decompression. To prospectively evaluate changes in portal hemodynamics and effective hepatic blood flow brought about by partial portal decompression, the following were determined in seven patients undergoing HGPCS: intraoperative pre- and postshunt portal vein pressures and portal vein-inferior vena cava pressure gradients, intraoperative pre- and postshunt portal vein flow, and pre- and postoperative effective hepatic blood flow. With HGPCS, portal vein pressures and portal vein-inferior vena cava pressure gradients decreased significantly, although portal pressures remained above normal. In contrast to the significant decreases in portal pressures, portal vein blood flow and effective hepatic blood flow do not decrease significantly. Changes in portal vein pressures and portal vein-inferior vena cava pressure gradients are great when compared to changes in portal vein flow and effective hepatic blood flow. Reduction of portal hypertension with concomitant maintenance of hepatic blood flow may explain why hepatic dysfunction is avoided following partial portal decompression.

    The quality of working relationships between service users and health providers is fundamental in the processes of recovery in mental health. How Internet-based interventions will influence these relationships for persons with long-term care needs, and the measures that can be taken to maintain and enhance working relationships through Internet, is still not well understood. The aim of this study was to gain insights into how service users and health providers experience their working relationships when they are offered the option of supplementing ongoing collaboration with an e-recovery portal. In this exploratory and descriptive study, an e-recovery portal was used by service users and their health providers in 2 mental health communities in Norway for at least 6 months and at most 12 months (2015-2016). The portal consists of secure messaging, a peer support forum, and a toolbox of resources for working with life domains including status, goals and activities, network map, crisis plan, and exercises. The portal was owned and managed by the service user while health providers could remotely access parts of the service user-generated content. The participants could use the portal in whatever way they wished, to suit their collaboration. Data from 6 focus groups, 17 individual interviews, and an interview with 1 dyad about their experiences of use of the portal over the study period were inductively coded and thematically analyzed. The thematic analysis resulted in 2 main themes: (1) new relational avenues and (2) out of alignment, illustrated by 8 subthemes. The first main theme is about dyads who reported new and enriching ways of working together through the portal, particularly related to written communication and use of the goal module. Illustrative subthemes are ownership, common ground, goals and direction, and sense of presence and availability. The second main theme illuminates the difficulties that arose when service users' and health providers

    Internet-derived health care information is increasingly accessed by patients, yet its quality and accuracy is variable and unregulated. The aim of this study was to assess the information available regarding common gastrointestinal cancers via three internet search engines (Google, Yahoo and Bing). The top 30 websites for each of the terms: oesophageal, gastric, pancreatic, colon and rectal cancer were evaluated (University of Michigan Consumer Health Website Checklist) and scored [-80 (poor) to 90 (excellent)]. The median score was 53 (-7 to 81) and was significantly higher for oesophageal (61) and pancreatic (65) cancer websites, compared with gastric (49), colon (48) and rectal cancer (50) (p = 0.014). Median scores related to charitable organisations were significantly better than academic, commercial, news agency, care provider, layperson and medical information websites collectively (79 vs. 42, p < 0.0001). Overall quality of internet-derived gastrointestinal cancer information remains poor and patients and clinicians should be aware.

    Background The MEDICOM (Medical Products Electronic Commerce) Portal provides the electronic means for medical-equipment manufacturers to communicate online with their customers while supporting the Purchasing Process and Post Market Surveillance. The Portal offers a powerful Internet-based search tool for finding medical products and manufacturers. Its main advantage is the fast, reliable and up-to-date retrieval of information while eliminating all unrelated content that a general-purpose search engine would retrieve. The Universal Medical Device Nomenclature System (UMDNS) registers all products. The Portal accepts end-user requests and generates a list of results containing text descriptions of devices, UMDNS attribute values, and links to manufacturer Web pages and online catalogues for access to more-detailed information. Device short descriptions are provided by the corresponding manufacturer. The Portal offers technical support for integration of the manufacturers' Web sites with itself. The network of the Portal and the connected manufacturers' sites is called the MEDICOM system. Objective To establish an environment hosting all the interactions of consumers (health care organizations and professionals) and providers (manufacturers, distributors, and resellers of medical devices). Methods The Portal provides the end-user interface, implements system management, and supports database compatibility. The Portal hosts information about the whole MEDICOM system (Common Database) and summarized descriptions of medical devices (Short Description Database); the manufacturers' servers present extended descriptions. The Portal provides end-user profiling and registration, an efficient product-searching mechanism, bulletin boards, links to on-line libraries and standards, on-line information for the MEDICOM system, and special messages or advertisements from manufacturers.

In this paper, we introduce the architecture of a Rich Internet Application (RIA that uses the power of Semantics to create a new type of Web Portal fully customizable that we will call MyE-Wall. In this portal, the user can’t attach widget, but modules containing each one the section of a particular web site. Therefore, the idea is allow a user to create of a new website composed by a patchwork of different website’s sections selected by himself. Here we use semantics for two reasons: (i to process the structure of a particular website and create the corresponding module to attach on the portal (ii to provide the application of a set of features (reasoning engine, swrl rules, etc... to reason on the information collected, according the preferences that the user

    Purpose: The relationship of the portalvein bifurcation to the liver capsule in Asians, which is an important landmark for transjugular intrahepatic portosystemic shunt, has not previously been described. Methods: The anatomy of the portal vein bifurcation was studied in 70 adult Chinese cadavers; it was characterized as intrahepatic or extrahepatic. The length of the exposed portion of the right and left portal veins was measured when the bifurcation was extrahepatic. Results: The portal vein bifurcation was intrahepatic in 37 cadavers (53%) and extrahepatic in 33 cadavers (47%). The mean length of the right and left extrahepatic portal veins was 0.96 cm and 0.85 cm respectively.Both were less than or equal to 2 cm in 94% of the cadavers with extrahepatic bifurcation. There was no correlation between the presence of cirrhosis and the location of the portal vein bifurcation(p 1.0). There was no statistically significant difference in liver mass in cadavers with either extrahepatic or intrahepatic bifurcation (p =0.40). Conclusions: These findings suggest that fortransjugular intrahepatic portosystemic shunt placement, a portal vein puncture 2 cm from the bifurcation will be safe in most cases

    Objective: To discuss the technical skills and the contraindication of trans-jugular intrahepatic portosystemic shunt stent (TIPSS) in portal vein cancerous thrombosis (PVCT) complicated with portal hypertension. Methods: There were 16 cases of PVCT with portal hypertension, and average age of 53.6 yr. There were 9 cases with complete occlusion of portal vein trunk and 7 cases with incomplete thrombosis. There were 5 cases with cavernous transformation of the portal vein (CTPV). 1 case of simple upper gastro-intestinal tract (GIT) massive bleeding, 4 with refractory ascites and 11 with upper GIT massive bleeding and refractory ascites. Results: The procedure of TIPS was successful in 11 cases, the successful rate reached about 68.8%. The mean portal vein pressure was reduced from 4.9 kPa to 2.4 kPa with average 2. 5 kPa reduction. Ascites decreased, bleeding stopped and the clinical symptoms disappeared. The average survival period was 136 days. The procedure failed in 5 cases. Conclusions: TIPSS is an effective method to control the bleeding and ascites caused by PVCT. The PV cavernous transformation was the contraindication of TIPSS

    2015-06-01

    Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

    2017-12-01

    To characterize online news coverage relating to mammography, including articles' stance toward screening mammography. Google News was used to search U.S. news sites over a 9-year period (2006-2015) based on the search terms "mammography" and "mammogram." The top 100 search results were recorded. Identified articles were manually reviewed. The top 100 news articles were from the following sources: local news outlet (50%), national news outlet (24%), nonimaging medical source (13%), entertainment or culture news outlet (6%), business news outlet (4%), peer-reviewed journal (1%), and radiology news outlet (1%). Most common major themes were the screening mammography controversy (29%), description of a new breast imaging technology (23%), dense breasts (11%), and promotion of a public screening initiative (11%). For the most recent year, article stance toward screening mammography was 59%, favorable; 16%, unfavorable; and 25%, neutral. After 2010, there was an abrupt shift in articles' stances from neutral to both favorable and unfavorable. A wide range of online news sources addressed a range of issues related to mammography. National, rather than local, news sites were more likely to focus on the screening controversy and more likely to take an unfavorable view. The controversial United States Preventive Services Task Force guidelines may have influenced articles to take a stance on screening mammography. As such online news may impact public perception of the topic and thus potentially impact guideline adherence, radiologists are encouraged to maintain awareness of this online coverage and to support the online dissemination of reliable and accurate information.

  11. Thrilling News Revisited: The Role of Suspense for the Enjoyment of News Stories.

    Science.gov (United States)

    Kaspar, Kai; Zimmermann, Daniel; Wilbers, Anne-Kathrin

    2016-01-01

    Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 ( n = 263) successfully replicated results of an earlier study, whereas Studies 2 ( n = 255) and 3 ( n = 599) challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics and news evaluation were relatively stable. In particular, participants' liking of the protagonist and the perceived likelihood of a good ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants' liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story's personal relevance was less influential than expected. Further, we observed a large absence of

    Purpose/Objective: The purpose of this presentation is to examine the various imaging devices that have been developed for portal imaging; describe some of the image registration methods that have been developed to determine geometric errors quantitatively; discuss some of the ways that portal imaging has been incorporated into routine clinical practice; describe quality assurance procedures for these devices, and discuss the use of portal imaging devices for dosimetry applications. Discussion: Verification of patient positioning has always been an important aspect of external beam radiation therapy. Over the past decade many portal imaging devices have been developed by individual investigators and most accelerator manufacturers now offer 'on-line' portal imaging systems. The commercial devices can be classified into three categories: T.V. camera-based systems, liquid ionisation chamber systems, and amorphous silicon systems. Many factors influence the quality of images generated by these portal imaging systems. These include factors which are unavoidable (e.g., low subject contrast), factors which depend upon the individual imaging device forming the image (e.g., dose utilisation, spatial resolution) as well as factors which depend upon the characteristics of the linear accelerator irradiating the imaging system (x-ray source size, image magnification). The characteristics of individual imaging systems, such as spatial resolution, temporal response, and quantum utilisation will be discussed. One of the major advantages of on-line portal imaging is that many quantitative techniques have been developed to detect errors in patient positioning. The general approach is to register anatomic structures on a portal image with the same structures on a digitized simulator film. Once the anatomic structures have been registered, any discrepancies in the position of the patient can be identified. However, the task is not nearly as straight-forward as it sounds. One problem

    Current large animal models that could closely resemble the typical features of cirrhotic portal hypertension in human have not been well established. Thus, we aimed to develop and describe a reliable and reproducible canine cirrhosis model of portal hypertension. A total of 30 mongrel dogs were randomly divided into four groups: 1 (control; n = 5), 2 (portal vein stenosis [PVS]; n = 5], 3 (thioacetamide [TAA]; n = 5), and 4 (PVS plus TAA; n = 15). After 4-months modeling period, liver and spleen CT perfusion, abdominal CT scans, portal hemodynamics, gastroscopy, hepatic function, blood routine, the bone marrow, liver, and spleen histology were studied. The animals in group 2 (PVS) developed extrahepatic portosystemic collateral circulation, particularly esophageal varices, without hepatic cirrhosis and portal hypertension. Animals from group 3 (TAA) presented mild cirrhosis and portal hypertension without significant symptoms of esophageal varices and hypersplenism. In contrast, animals from group 4 (PVS + TAA) showed well-developed micronodular and macronodular cirrhosis, associated with significant portal hypertension and hypersplenism. The combination of PVS and TAA represents a novel, reliable, and reproducible canine cirrhosis model of portal hypertension, which is associated with the typical characteristics of portal hypertension, including hypersplenism.

    Full Text Available Introduction: The process of education of a patient aims to improve knowledge and skill of the patient and/or family, in a way to influence attitudes and behaviors needed to maintain or improve health. Must be a integral part of interpersonal communication between health professionals and patients, and this can happen through interpersonal communication and various other means such as pamphlets, manuals and, more recently, computer resources. Goal: This update article approach the patient education and the internet potential for this process, still presenting some initiatives in the audiology área. Discussion: The informations, related to health are popular in the internet, and include interactive websites, portals, e-mails, telehealth aplications, and others. The education of the patients supported by the internet can help to solve a big ethical, political and economic issue: the problem to conciliate the needs and the expectations of the patients with the characteristics and limitations of the health system. Although the use of internet in the education of the patient is promising, this is not a solution to be used without careful planning, monitoring and evaluation. In audiology there are few initiatives with the use of e-mails and websites for complement of the patient education. Final Considerations: The health professionals, including the speech therapists, must check if their patients use internet resources, recognize that behavior change and prepare not only to discuss the information obtained with the patient, but also suggest websites with reliable information and help them to evaluate the quality of the information available online.

    Full Text Available This study examines social network diversity in urban areas relative to residents’ usage of information and communication technologies (ICTs. Individual-level variation in social network diversity was measured using position generator data collected as part of a survey conducted in Malaysia’s Klang Valley (N = 808. Regression analyses were performed to assess the extent to which network diversity is related to ICTs. We find that most ICTs have a negative effect on diversity. Only frequent use of the Internet at work, mobile access to the Internet, and reading online news or blogs contribute positively to diversity. Findings support both a tendency toward ‘networked individualism’ and the more recent ‘glocalization’ thesis that some ICTs may also afford participation within local space rather than only across distant space.

    Purpose/Objective: The purpose of this presentation is to examine the various imaging devices that have been developed for portal imaging, describe some of the image registration methods that have been developed to determine geometric errors quantitatively, and discuss how portal imaging has been incorporated into clinical practice. Discussion: Verification of patient positioning has always been an important aspect of external beam radiation therapy. Over the past decade many portal imaging devices have been developed by individual investigators and most accelerator manufacturers now offer 'on-line' portal imaging systems. The commercial devices include T.V. camera-based systems, liquid ionisation chamber systems, and shortly, flat panel systems. The characteristics of these imaging systems will be discussed. In addition, other approaches such as the use of kilovoltage x-ray sources, video monitoring, and ultrasound have been proposed for improving patient positioning. Some of the advantages of these approaches will be discussed. One of the major advantages of on-line portal imaging is that many quantitative techniques have been developed to detect errors in patient positioning. The general approach is to register anatomic structures on a portal image with the same structures on a digitized simulator film. Once the anatomic structures have been registered, any discrepancies in the position of the patient can be identified. One problem is finding a common frame of reference for the simulator and portal images, since the location of the radiation field within the pixel matrix may differ for the two images. As a result, a common frame of reference has to be established before the anatomic structures in the images can be registered - generally by registering radiation field edges identified in the simulator and portal images. In addition, distortions in patient geometry or rotations out of the image plane can confound the image registration techniques. Despite the

    Off-line, computer-aided prescription (simulator) and treatment (portal) image registration using chamfer matching has been implemented on PC based viewing station. The purposes of this study were (a) to evaluate the performance of interactive anatomy and field edge extraction and subsequent registration, and (b) to compare observer's perceptions of field accuracy with measured discrepancies following anatomical registration. Prescription-treatment image pairs for 48 different patients were examined in this study. Digital prescription images were produced with the aid of a television camera and a digital frame grabber, while the treatment images were obtained directly from an on-line portal imaging system. To facilitate perception of low contrast anatomical detail, on-line portal images were enhanced with selective adaptive histogram equalization prior to extraction of anatomical edges. Following interactive extraction of anatomical and field border information by an experienced observer, the identified anatomy was registered using chamfer matching. The degree of conformity between the prescription and treatment fields was quantified using several parameters, which included relative prescription field coverage and overcoverage, as well as the translational and rotational displacements as measured by chamfer matching applied to the boundaries of the two fields. These quantitative measures were compared with subjective evaluations made by four radiation oncologists. All the images in this series that included a range of the most commonly seen treatment sites were registered and the conformity parameters were found. The mean treatment/prescription field coverage and overcoverage were approximately 95 and 7%, respectively before registration. The mean translational displacement in the transverse and cranio-caudal directions were 2.9 and 3.4 mm, respectively. The mean rotational displacement was approximately 2 degrees. For all four oncologists, the portals classified

    The Sydney West Translational Cancer Research Centre is an organization funded to build capacity for translational research in cancer. Translational research is essential for ensuring the integration of best available evidence into practice and for improving patient outcomes. However, there is a low level of awareness regarding what it is and how to conduct it optimally. One solution to addressing this gap is the design and deployment of web-based knowledge portals to disseminate new knowledge and engage with and connect dispersed networks of researchers. A knowledge portal is an web-based platform for increasing knowledge dissemination and management in a specialized area. To measure the design and growth of an web-based knowledge portal for increasing individual awareness of translational research and to build organizational capacity for the delivery of translational research projects in cancer. An adaptive methodology was used to capture the design and growth of an web-based knowledge portal in cancer. This involved stakeholder consultations to inform initial design of the portal. Once the portal was live, site analytics were reviewed to evaluate member usage of the portal and to measure growth in membership. Knowledge portal membership grew consistently for the first 18 months after deployment, before leveling out. Analysis of site metrics revealed members were most likely to visit portal pages with community-generated content, particularly pages with a focus on translational research. This was closely followed by pages that disseminated educational material about translational research. Preliminary data from this study suggest that knowledge portals may be beneficial tools for translating new evidence and fostering an environment of communication and collaboration.

    Objective: To evaluate the palliative therapeutic effects of transjugular intrahepatic portosystemic shunt (TIPS) in portal vein tumor thrombosis (PVTT) complicated with portal vein hypertension, and to discuss the technical skills. Methods: There were 14 cases of end-stage hepatocellular carcinoma complicated with PVTT and portal vein hypertension, the average age was 53.6 yr. There were 8 cases with complete occlusion of main portal vein, 6 eases with incomplete thrombosis, and 5 cases combined with portal vein cavernous transformation. One case had simple hemorrhage, 3 eases had intractable ascites, and 10 cases had hemorrhage accompanied by intractable ascites. Results: The procedure of TIPS was successful in 10 cases, the successful rate was about 71%. The mean portal vein pressure was reduced from 37.2 mm Hg to 18.2 mm Hg, with an average reduction of 19.0 mm Hg. After the procedure of TIPS, the ascites decreased, hemorrhage stopped and the clinical symptoms disappeared. The average survival period was 132.3 days. The procedure were failing in 4 cases. Conclusion: TIPS was an effective palliative therapeutic methods to control the hemorrhage and ascites aroused by hepatic carcinoma complicated with PVTT

  9. Thrilling news revisited: The role of suspense for the enjoyment of news stories

    Directory of Open Access Journals (Sweden)

    Full Text Available Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 (n = 263 successfully replicated results of an earlier study, whereas Studies 2 (n = 255 and 3 (n = 599 challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics were relatively stable. In particular, a higher liking of the protagonist and a higher perceived likelihood of a good versus bad ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and it contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants’ liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story’s personal relevance was less influential than expected. Further, we observed a large

    Full Text Available There has been a growing academic interest in the role of new communication technology in the political process in Asia. The increasing influence of the Internet to diffuse political information may have facilitated high voter involvement in the political process in this region. This study examines patterns of on-line and traditional news media use among people who have access to the Internet in Malaysia. The results show an association between the use of the Internet and traditional media -- newspapers, television, and radio -- for political information among the respondents interviewed. This study suggests that the Internet is widely used to gather political information, but its use for this purpose is not replacing the newspapers and television. There is also an indication that the Internet users participate online in a limited number of political activities. However, the political knowledge gained from the Internet does not seem to influence the respondents’ choice of political candidate in elections.

    Visceral angiography was performed in 7 patients with normal portal pressure and in 10 with portal hypertension. Circulation times, size of vessels and portal pressure were determined. At celiac angiography, a direct correlation was found between time for maximum filling of portal vein and portal pressure, provided no vascular abnormalities existed. At superior mesenteric angiography such a correlation was not found; loss of flow by shunts in portal hypertension being one explanation. Portocaval shunts are common in the celiac system, but uncommon in the superior mesenteric system.

    The quality of communication with patients and family members in intensive care units (ICUs) is a focus of current interest for clinical care improvement. Electronic communication portals are commonly used in other healthcare settings to improve communication. We do not know whether patients and family members desire such portals in ICUs, and if so, what functionality they should provide. To define interest in and desired elements of an electronic communication portal among current and potential ICU patients and their family members. We surveyed, via an Internet panel, 1,050 English-speaking adults residing in the United States with a personal or family history of an ICU admission within 10 years (cohort A) and 1,050 individuals without a history of such admission (cohort B). We also administered a survey instrument in person to 105 family members of patients currently admitted to ICUs at an academic medical center in Boston (cohort C). Respondents, especially current ICU family members, supported an electronic communication portal, including access via an electronic tablet. They wanted at least daily updates, one-paragraph summaries of family meetings including a list of key decisions made, and knowledge of the role and experience of treating clinicians. Overall, they preferred detailed rather than "big picture" information. Respondents were generally comfortable sharing information with their family members. Preferences regarding a communication portal varied significantly by age, sex, ethnicity, and prior experience with ICU hospitalization. Electronic communication portals appear welcome in contemporary ICUs. Frequent updates, knowledge about the professional qualifications of clinicians, detailed medical information, and documentation of family meetings are particularly desired.

    2012-11-09

    Health care professionals' attitudes can be a significant factor in their acceptance and efficient use of information technology, so they need to have more knowledge about this resource to enhance their participation. We explored practitioners' perceptions of using an open-access interactive Web portal tailored to young diabetes type 1 patients and their guardians or significant others. The portal offered discussion forums, blog tools, self-care and treatment information, research updates, and news from local practitioners. Eighteen professionals who were on pediatric diabetes care teams each wrote an essay on their experience using the portal. For their essays, they were asked to describe two situations, focusing on positive and negative user experiences. The essays were analyzed using qualitative content analysis. Based on our analysis of the respondents essays, we identified three categories that describe perceptions of the Web portal. The first category - to use or not to use - included the different perspectives of the practioners; those who questioned the benefits of using the Web portal or showed some resistance to using it. The frequency of use among the practitioners varied greatly. Some practitioners never used it, while others used it on a daily basis and regularly promoted it to their patients. Some respondents in this category reflected on the benefits of contributing actively to online dialogues. In the second category - information center for everyone - practitioners embraced the site as a resource for scientifically sound information and advice. As part of their practice, and as a complement to traditional care, practitioners in this category described sending information through the portal to patients and their significant others. Practitioners felt safe recommending the site because they knew that the information provided was generated by other practitioners. They also assumed that their patients benefited from actively using the Web portal at

    To evaluate the feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in patients with active variceal bleeding due to liver cirrhosis and pre-existing portal vein thrombosis. Of a total of 123 patients who underwent TIPS, 14 patients with intractable variceal bleeding due to portal hypertension and portal vein thrombosis were included in this study. Noncavernomatous portal vein occlusion was seen in eight patients, and complete portal vein occlusion with cavernomatous trans-formation in six. For all patients, the methods used for TIPS placement were the same as those used in patients with patents portal veins. In seven of eight patients with noncavernomatous occlusion, right hepatic vein-right portal vein shunting was performed; in one with knoncavernomatous occlusion, a shunt was created between the right hepatic and left portal vein. In five of six patients with cavernomatous occlusion, the right hepatic and main portal vein were connected via a collateral vein. The procedures were technically successful in all except one patient. Immediate hemostatis was achieved after all technically successful procedures, and no significant complications were encountered. Minor complications were noted in six patients (three biliary tree punctures, one transperitoneal puncture, one splenic vein perforation, one hepatic subcapsular hematoma). TIPS is a technically feasible and hemodynamically effective procedure, even in patients with active variceal bleeding due to cirrhosis and complete portal vein occlusion

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

  4. The History of the Internet Search Engine: Navigational Media and the Traffic Commodity

    van Couvering, E.

    This chapter traces the economic development of the search engine industry over time, beginning with the earliest Web search engines and ending with the domination of the market by Google, Yahoo! and MSN. Specifically, it focuses on the ways in which search engines are similar to and different from traditional media institutions, and how the relations between traditional and Internet media have changed over time. In addition to its historical overview, a core contribution of this chapter is the analysis of the industry using a media value chain based on audiences rather than on content, and the development of traffic as the core unit of exchange. It shows that traditional media companies failed when they attempted to create vertically integrated portals in the late 1990s, based on the idea of controlling Internet content, while search engines succeeded in creating huge "virtually integrated" networks based on control of Internet traffic rather than Internet content.

    Portals, an experimental feature of 4.4BSD, extend the file system name space by exporting certain open () requests to a user-space daemon. A portal daemon is mounted into the file name space as if it were a standard file system. When the kernel resolves a pathname and encounters a portal mount point, the remainder of the path is passed to the portal daemon. Depending on the portal "pathname" and the daemon's configuration, some type of open (2) is performed. The resulting file descriptor is passed back to the kernel which eventually returns it to the user, to whom it appears that a "normal" open has occurred. A proxy portalfs file system is responsible for kernel interaction with the daemon. The overall effect is that the portal daemon performs an open (2) on behalf of the kernel, possibly hiding substantial complexity from the calling process. One particularly useful application is implementing a connection service that allows simple scripts to open network sockets. This paper describes the implementation of portals for LINUX 2.0.

    Internet portal technologies that provide access to portions of electronic health records have the potential to revolutionize patients' involvement in their care. However, relatively few descriptions of the demographic characteristics of portal enrollees or of the effects of portal technology on quality outcomes exist. This study examined data from patients who attended one of seven Duke Medicine clinics and who were offered the option of enrolling in and using the Duke Medicine HealthView portal (HVP). The HVP allows patients to manage details of their appointment scheduling and provides automated email appointment reminders in addition to the telephone and mail reminders that all patients receive. Our objective was to test whether portal enrollment with an email reminder functionality is significantly related to decreases in rates of appointment "no-shows," which are known to impair clinic operational efficiency. Appointment activity during a 1-year period was examined for all patients attending one of seven Duke Medicine clinics. Patients were categorized as portal enrollees or as nonusers either by their status at time of appointment or at the end of the 1-year period. Demographic characteristics and no-show rates among these groups were compared. A binomial logistic regression model was constructed to measure the adjusted impact of HVP enrollment on no-show rates, given confounding factors. To demonstrate the effect of HVP use over time, monthly no-show rates were calculated for patient appointment keeping and contrasted between preportal and postportal deployment periods. Across seven clinics, 58,942 patients, 15.7% (9239/58,942) of whom were portal enrollees, scheduled 198,199 appointments with an overall no-show rate of 9.9% (19,668/198,199). We found that HVP enrollees were significantly more likely to be female, white, and privately insured compared with nonusers. Bivariate no-show rate differences between portal enrollment groups varied widely according

    Purpose: Off-line, computer-aided prescription (simulator) and treatment (portal) image registration using chamfer matching has been implemented on PC based viewing station. The purposes of this study were (a) to evaluate the performance of interactive anatomy and field edge extraction and subsequent registration, and (b) to compare observer's perceptions of field accuracy with measured discrepancies following anatomical registration. Methods and Materials: Prescription-treatment image pairs for 48 different patients were examined in this study. Digital prescription images were produced with the aid of a television camera and a digital frame grabber, while the treatment images were obtained directly from an on-line portal imaging system. To facilitate perception of low contrast anatomical detail, on-line portal images were enhanced with selective adaptive histogram equalization prior to extraction of anatomical edges. Following interactive extraction of anatomical and field border information by an experienced observer, the identified anatomy was registered using chamber matching. The degree of conformity between the prescription and treatment fields was quantified using several parameters, which included relative prescription field coverage and overcoverage, as well as the translational and rotational displacements as measured by chamfer matching applied to the boundaries of the two fields. These quantitative measures were compared with subjective evaluations made by four radiation oncologists. Results: All the images in this series that included a range of the most commonly seen treatment sites were registered and the conformity parameters were found. The mean treatment/prescription field coverage and overcoverage were approximately 95 and 7%, respectively before registration. The mean translational displacement in the transverse and cranio-caudal directions were 2.9 and 3.4 mm, respectively. The mean rotational displacement was approximately 2 deg. . For all

    Portal monitors are an important part of the material protection, control, and accounting (MPC and A) programs in Russia and the US. Although portal monitors are only a part of an integrated MPC and A system, they are an effective means of controlling the unauthorized movement of special nuclear material (SNM). Russian technical experts have gained experience in the use of SNM portal monitors from US experts ad this has allowed them to use the monitors more effectively. Several Russian institutes and companies are designing and manufacturing SNM portal monitors in Russia. Interactions between Russian and US experts have resulted in improvements to the instruments. SNM portal monitor technology has been effectively transferred from the US to Russia and should be a permanent part of the Russian MPC and A Program. Progress in the implementation of the monitors and improvements to how they are used are discussed

    In the environmental sciences, researchers are increasingly relying on automated sensors as necessary components of their work. There are many software packages available that will help users download data from internet-connected data loggers; process, store, document, and analyze the data; or provide web-based geoportals for visualization and sharing of both spatial and time-series data. However, few (if any) software packages provide a complete, end-to-end system that will meet all of the needs of any given research group. Such systems often need to be designed and built as needed. Our group specializes in creating such systems. Our portals provide rapid data discovery and contextualization, and promote collaboration. We work at multiple scales, from a small lab working at a single site in the Chihuahuan desert (SEL-Jornada), to a community portal for environmental data from Barrow, Alaska (Barrow Area Information Database Information Management System [BAID-IMS]), to a project-tracking system for US Arctic research efforts (Arctic Research Mapping Application/Arctic Observing Viewer [ARMAP/AON]). Here, we share our experiences of creating scalable systems and improving practices that address both user community and research needs.

    Purpose/Objective: In order to ensure the treatment is delivered as planned, a portal image is acquired in the accelerator and is compared to the reference image. At present, this comparison is performed by radiation oncologists based on the manually-identified features, which is both time-consuming and potentially error-prone. With the introduction of various electronic portal imaging devices, real-time patient positioning correction is becoming clinically feasible to replace time-delayed analysis using films. However, this procedure requires present of radiation oncologists during patient treatment which is not cost-effective and practically not realistic. Therefore, the efficiency and quality of radiation therapy could be substantially improved if this procedure can be automated. The purpose of this study is to develop a fully computerized verification system for the radiation therapy of breast cancer for which a similar treatment setup is generally employed. Materials/Methods: The automated verification system involves image acquisition, image feature extraction, feature correlation between reference and portal images, and quantitative evaluation of patient setup. In this study, a matrix liquid ion-chamber EPID was used to acquire digital portal images which is directly attached to Varian CL2100C accelerator. For effective use of computation memory, the 12-bit gray levels in original portal images were quantized to form a range of 8-bit gray levels. A typical breast portal image includes three important components: breast and lung tissues in the treatment field, air space within the treatment field, and non-irradiated region. A hierarchical region processing technique was developed to separate these regions sequentially. The inherent hierarchical features were formulated based on different radiation attenuation for different regions as: treatment field edge -- breast skin line -- chest wall. Initially, a combination of a Canny edge detector and a constrained

    Despite the growing penetration of the Internet, little is known about the usage and browsing patterns of those in poverty. We report on a randomized controlled trial that sheds light on the Internet use and browsing patterns among the urban poor. The data come from 312 participants in Boston, Massachusetts, from Click to Connect, a study that examined the impact of an intervention that provided computers, Internet, and training to people from lower socioeconomic position (SEP). Data were gathered through pre- and posttest surveys and Internet use tracking software that generated approximately 13 million network activity files and more than 5.5 million records. Internet use increased among intervention participants, with most of their time spent on social and participatory media sites or Internet portals. Differential patterns of use by gender and race/ethnicity were observed. Purposive searching for health information was low among all participants. Most of the visits to health-related sites were to local hospitals' sites suggesting the influence of possible preexisting relationships and trust. Social networking sites were frequently visited, with three sites enjoying similar popularity among all groups. Our data show that the availability of Internet can lead to significant increase in its use among low SEP groups. Low SEP members used the Internet for participation and engagement, but the sites visited differed by group. Harnessing the power of social networking sites and shareware sites may be a way to increase access to health information.

    The intranet portal (named IntraNEK) at Krsko NPP serves as a single entry point to access the internet and various plant applications and links. The front page consists of the standard internet search bar and links to various applications that can either reside within the technological computer network (TRM) or within the plant business computer network. Access to the TRM applications is read only. Some applications on the business computer network are open to all personnel who log on to the network while some applications are restricted and secured, and require additional login entries. A selected link will open in a new window. Documents will open with the appropriate software tool depending on the document file format. Some categories of documents are available in image form only (e.g. procedures, drawings etc.), while some are available in fully searchable PDF format (e.g. technical specifications, updated safety analysis reports (USARs) etc.). Plant departments (organizational units) have their own pages accessible from the front page. Their pages contain links to their own information resources or links to other resources and applications, tailored to the department needs. During recent years a number of web based applications have been developed that are connected also with a common Oracle database. Some are designed to serve for data entry and browsing while others serve for browsing only

    In patients with portal hypertension, the blood flow volume is maintained despite decreased blood flow velocity due to enlargement of the vascular cross sectional area. Thus, the 'congestion index' of the portal vein, which is the ratio between the cross sectional area (cm2) and the blood flow velocity (cm/sec) determined by a Doppler ultrasonography, may be a sensitive index by which to assess portal hypertension. We performed Doppler ultrasonography on 24 normal subjects, 14 patients with biopsy proved chronic active hepatitis and 55 patients with liver cirrhosis in order to assess the diagnostic value of the congestion index. The cross sectional area of the portal vein was significantly enlarged and the mean blood flow velocity was significantly reduced in patients with liver cirrhosis compared with controls. However, the blood flow volume was no difference. The congestion index of the portal vein was significantly increased in patients with liver cirrhosis (0.113+0.035) compared with patients with chronic active hepatitis(0.078+0.029) (p<0.001) and controls (0.053+0.016) (p<0.001). The sensitivity, specificity and predictability of the congestion index for detection of patients with the cirrhosis of the liver were 76.4%, 100% and 100% respectively, when the normal range was set at mean+2SD. The results suggest that the congestion index of the portal vein may pla a significant role in diagnosis of portal hypertensive patients

    Full Text Available Studies have shown that authoritarian regimes tend to censor the media to limit potential threats to the status quo. While such censorship practices were traditionally aimed at broadcast and print media, the emergence of the Internet and social media in particular, prompted some authoritarian regimes, such as the Assad regime in Syria, to try and exert a similar level of censorship on the Internet as well. During the Arab Spring, the Syrian regime blocked hundreds of websites that provided social networking, news, and other services. Taking Syria as a case study, this paper examines whether Internet censorship succeeded in preventing Internet users from reaching censored online content during 2010−2012. By analyzing the use of Alkasir, a censorship circumvention tool created by the author, the paper provides empirical evidence demonstrating that users were in fact able to bypass censorship and access blocked websites. The findings demonstrate that censorship circumvention tools constituted a threat to the information control systems of authoritarian regimes, highlighting the potential of such tools to promote online freedom of expression in countries where Internet censorship is prevalent.

    2015-06-01

    Health literacy has been described as the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions. Improving health literacy may serve to promote concordance with therapy, engage patients in their own health care, and improve health outcomes. Patient portal technology aims at enabling patients and families to have easy access to key information in their own medical records and to communicate with their health care providers electronically. However, there is a gap in our understanding of how portals will improve patient outcome. The authors believe patient portal technology presents an opportunity to improve patient concordance with prescribed therapy, if adequate support is provided to equip patients (and family/carers) with the knowledge needed to utilise the health information available via the portals. Research is needed to understand what a health consumer will use patient portals for and how to support a user to realise the technology's potential.

    Purpose/Objective: The purpose of this presentation is to review the physics of imaging with high energy x-ray beams; examine the various imaging devices that have been developed for portal imaging; describe some of the image registration methods that have been developed to determine errors in patient positioning quantitatively; and discuss some of the ways that portal imaging has been incorporated into routine clinical practice. Verification of patient positioning has always been an important aspect of external beam radiation therapy. Checks of patient positioning have generally been done with film, however, film suffers from a number of drawbacks, such as poor image display and delays due to film development. Over the past decade many portal imaging devices have been developed by individual investigators and most accelerator manufacturers now offer 'on-line' portal imaging systems, which are intended to overcome the limitations of portal films. The commercial devices can be classified into three categories: T.V. camera-based systems, liquid ionisation chamber systems, and amorphous silicon systems. Many factors influence the quality of images generated by these portal imaging systems. These include factors which are unavoidable (e.g., low subject contrast), factors which depend upon the individual imaging device forming the image (e.g., dose utilisation, spatial resolution) as well as factors which depend upon the characteristics of the linear accelerator irradiating the imaging system (x-ray source size, image magnification). The fundamental factors which limit image quality and the characteristics of individual imaging systems, such as spatial resolution, temporal response, and quantum utilisation will be discussed. One of the major advantages of on-line portal imaging is that many quantitative techniques have been developed to detect errors in patient positioning. The general approach is to register anatomic structures on a portal image with the same

    Even though pregnancy is rare with cirrhosis and advanced liver disease, but it may co-exist in the setting of non-cirrhotic portal hypertension as liver function is preserved but whenever encountered together is a complex clinical dilemma. Pregnancy in a patient with portal hypertension presents a special challenge to the obstetrician as so-called physiological hemodynamic changes associated with pregnancy, needed for meeting demands of the growing fetus, worsen the portal hypertension thereby putting mother at risk of potentially life-threatening complications like variceal hemorrhage. Risks of variceal bleed and hepatic decompensation increase many fold during pregnancy. Optimal management revolves round managing the portal hypertension and its complications. Thus management of such cases requires multi-speciality approach involving obstetricians experienced in dealing with high risk cases, hepatologists, anesthetists and neonatologists. With advancement in medical field, pregnancy is not contra-indicated in these women, as was previously believed. This article focuses on the different aspects of pregnancy with portal hypertension with special emphasis on specific cause wise treatment options to decrease the variceal bleed and hepatic decompensation. Based on extensive review of literature, management from pre-conceptional period to postpartum is outlined in order to have optimal maternal and perinatal outcomes. PMID:25755552

The aim of this study was to determine whether blood in the stomach lumen increases splanchnic flow and portal pressure (PP) in portal-hypertensive rats. superior mesenteric artery flow and PP were measured in conscious, unrestrained, fasted partial portal vein-ligated rats with chronically implanted Doppler flow probes or portal vein catheters before and after gavage with heparinized, warmed blood from donor rats, air, standard meal, or empty tube. Percentage of changes in flow and pressure from baseline were significantly greater after gavage with blood (an increase of 22.6% +/- 3.5% and an increase of 16.4% +/- 3.1%, respectively) than empty tube (an increase of 3.4% +/- 0.6% and a decrease of 5.4% +/- 3.5%, respectively) (P empty tube (P calories probably contributes to these hemodynamic changes. In patients with variceal hemorrhage, blood in the stomach may increase the risk of persistent variceal bleeding or rebleeding.

    The study aimed to describe portal stenting for postoperative portal occlusion with delayed (≥ 3 months) variceal bleeding in the afferent jejunal loop. Eleven consecutive patients (age range, 2–79 years; eight men and three women) who underwent portal stenting between April 2009 and December 2015 were included in the study. Preoperative medical history and the postoperative clinical course were reviewed. Characteristics of portal occlusion and details of procedures were also investigated. Technical success, treatment efficacy (defined as disappearance of jejunal varix on follow-up CT), and clinical success were analyzed. Primary stent patency rate was plotted using the Kaplan-Meier method. All patients underwent hepatobiliary-pancreatic cancer surgery except two children with liver transplantation for biliary atresia. Portal occlusion was caused by benign postoperative change (n = 6) and local tumor recurrence (n = 5). Variceal bleeding occurred at 27 months (4 to 72 months) and portal stenting was performed at 37 months (4 to 121 months), on average, postoperatively. Technical success, treatment efficacy, and clinical success rates were 90.9, 100, and 81.8%, respectively. The primary patency rate of portal stent was 88.9% during the mean follow-up period of 9 months. Neither procedure-related complication nor mortality occurred. Interventional portal stenting is an effective treatment for delayed jejunal variceal bleeding due to portal occlusion after hepatobiliary-pancreatic surgery.

    The aim of the present study was to elucidate the effect of transmembrane protein 16A (TMEM16A) on portal vein smooth muscle cell (PVSMC) proliferation associated with portal vein remodeling in portal hypertension (PHT). Sprague-Dawley rats were subjected to bile duct ligation to establish a rat model of liver cirrhosis and PHT. Sham-operated animals served as controls. At 8 weeks after bile duct ligation, the extent of liver fibrosis and the portal vein wall thickness were assessed using hematoxylin-eosin staining. The protein expression levels of TMEM16A, extracellular signal-regulated kinase 1 and 2 (ERK1/2) and phosphorylated ERK1/2 (p-ERK1/2) in the portal vein were detected by immunohistochemistry and western blotting. In vitro , the lentivirus vectors were constructed and transfected into PVSMCs to upregulate the expression of TMEM16A. Isolated rat primary PVSMCs were treated with a small molecule inhibitor of TMEM16A, T16A-inhA01. Cell cycle was detected by flow cytometry. The activity of TMEM16A in the portal vein isolated from bile duct ligated rats was decreased, while the expression level of p-ERK1/2 was increased. However, in vitro , upregulation of TMEM16A promoted the proliferation PVSMCs, while inhibition of TMEM16A channels inhibited the proliferation of PVSMCs. The results indicated that TMEM16A contributes to PVSMCs proliferation in vitro , but in vivo , it may be a negative regulator of cell proliferation influenced by numerous factors.

    1995-01-01

    In this contribution, the authors give an account of a rare case of a cavernous transformation of the portal vein that may have originated secondarily in a proliferative hematogenous disease with a polyglobulia and thrombosis in the periferal blood count as well as development of portal hypertension of a prehepatal type. The state of hyper-coagulation in a myeloproliferative disease may have lead to a chronic thrombosis of the portal vein with a subsequent malformation of the portal vein in terms of a cavernous transformation of the portal vein. The case is an interesting one because of the discrepancy between the gravity of the thrombotic complication and slightness of the symptoms in the clinical picture. The authors point out the importance of ultrasonography and computed tomography examination following the intravenous application of a water solution of a contrast medium in a morphologic diagnosing of a rare complication of a chronic thrombotic clot of the portal vein - the cavernous transformation.

    2017-07-01

    Full Text Available This study examines the impacts of news authorship and news sources on environmental coverage in the Nigerian press to shed light on the roles they play in news construction. The study finds that journalists in conjunction with policy makers are the catalyst for environmental information, whereas citizens who are pivotal in creating relevant public opinion on environmental issues are left behind. The study reveals that investigative reporting lacks in environmental coverage because most coverage are events driven which explains why environmental news is reported as straight news and as such journalists rely heavily on official sources rather than subsidiary sources. The study opines that for proper environmental coverage, journalists must choose sources from both main and subsidiary actors and revert to proactive, investigative and interpretive reporting so as to make environmental stories relatable to the intended audiences.

    The Internet has increasingly become an intrinsic part of everyday life, offering countless possibilities for education, services, recreation, and more. In fact, an entire virtual life within the digitalized World Wide Web is possible and common among many Internet users. Today's psychiatrists must therefore incorporate this dimension of human life into clinical practice, to achieve an adequate assessment of the tools and risks available to the patient. We focus on the Internet as a portal for the trade of and access to substances of abuse. We review the legal regulations that may inform care and standards of practice and analyze the difficulties that arise in assessment and monitoring of the current situation. We consider the potential impact of Internet-based narcotics trade on addiction morbidities and the practice of clinical psychiatry, as well as on the potential legal implications that the forensic expert may face.

    To obtain the morphological and biomechanical remodeling of portal veins in swine with portal hypertension (PHT), so as to provide some mechanical references and theoretical basis for clinical practice about PHT. Twenty white pigs were used in this study, 14 of them were subjected to both carbon tetrachloride- and pentobarbital-containing diet to induce experimental liver cirrhosis and PHT, and the remaining animals served as the normal controls. The morphological remodeling of portal veins was observed. Endothelial nitric oxide synthase expression profile in the vessel wall was assessed at both mRNA and protein level. The biomechanical changes of the hepatic portal veins were evaluated through assessing the following indicators: the incremental elastic modulus, pressure-strain elastic modulus, volume elastic modulus, and the incremental compliance. The swine PHT model was successfully established. The percentages for the microstructural components and the histological data significantly changed in the experimental group. Endothelial nitric oxide synthase expression was significantly downregulated in the portal veins of the experimental group. Three incremental elastic moduli (the incremental elastic modulus, pressure-strain elastic modulus, and volume elastic modulus) of the portal veins from PHT animals were significantly larger than those of the controls (P portal vein decreased. Our study suggests that the morphological and biomechanical properties of swine hepatic portal veins change significantly during the PHT process, which may play a critical role in the development of PHT and serve as potential therapeutic targets during clinical practice.

    Full Text Available PURPOSE: The purpose of this study was to assess portal hemodynamics in patients with portal hypertension due to hepatosplenic schistosomiasis as well as to assess the contribution of splanchnic hyperflow to the pathophysiology of the portal hypertension. METHODS: Sixteen patients with schistosomal portal hypertension and previous history of upper digestive bleeding due to esophageal varices rupture underwent elective esophagogastric devascularization and splenectomy and were prospectively studied. All patients underwent intraoperative invasive hemodynamic portal monitoring with a 4F-thermodilution catheter. The intraoperative portal hemodynamic assessment was conducted after laparotomy (initial and after esophagogastric devascularization (final. RESULTS: The initial portal pressure was elevated (mean 28.5 ± 4.5 mm Hg, and a significant drop of 25% was observed at the end of the surgery (21.9 ± 4.9 mm Hg. The initial portal flow was elevated (mean 1766.9 ± 686.6 mL/min. A significant fall (42% occurred at the end of the surgical procedure (1025.62 ± 338.7 mL/min. Fourteen patients (87.5% presented a portal flow of more than 1200 mL/min, and in 5 cases, values greater than 2000 mL/min were observed. CONCLUSIONS: Esophagogastric devascularization and splenectomy promote a significant reduction of the elevated portal pressure and flow in schistosomal portal hypertension. These data favor the hypothesis of portal hyperflow in the physiopathology of portal hypertension of schistosomiasis.OBJETIVOS: o objetivo do presente estudo é estudar a hemodinâmica portal em pacientes com hipertensão portal secundária a forma hepatoesplênica da esquistossomose e avaliar a contribuição do hiperfluxo esplênico na sua fisiopatologia CASUÍSTICA E MÉTODOS: Foram estudados prospectivamente 16 pacientes portadores de hipertensão portal secundária à forma hepatoesplênica da esquistossomose mansônica com indicação de tratamento cirúrgico.

    Interest in sharing interdisciplinary environmental modeling results and related data is increasing among scientists. The U.S. Geological Survey Geo Data Portal project enables data sharing by assembling open-standard Web services into an integrated data retrieval and analysis Web application design methodology that streamlines time-consuming and resource-intensive data management tasks. Data-serving Web services allow Web-based processing services to access Internet-available data sources. The Web processing services developed for the project create commonly needed derivatives of data in numerous formats. Coordinate reference system manipulation and spatial statistics calculation components implemented for the Web processing services were confirmed using ArcGIS 9.3.1, a geographic information science software package. Outcomes of the Geo Data Portal project support the rapid development of user interfaces for accessing and manipulating environmental data.

    To improve knowledge and to encourage active involvement of young adults with juvenile idiopathic arthritis (JIA), an informative website with written and video information and an online portal with access to the personal medical record, self-monitoring, and e-consult functionalities were developed. Before implementing these applications in daily practice, it is important to gain insight into their feasibility in terms of ease of use, perceived usefulness and intention to use. The aim of this study was to evaluate and to examine the feasibility of the website and the online portal for young adults with JIA. A qualitative, feasibility study was conducted among the first users: 13 young adults with JIA. After provided access to the website and online portal, patients were interviewed on perceived usefulness, ease of use, and intention to (re)use the applications. Participants in the study considered the website and online portal as useful and easy-to-use. New medical information and feedback would motivate them to revisit the applications again. On the website, videos showing other young adults, telling how they handle their condition, were found as the most useful. On the portal, access to their medical records was most appreciated: it made the young JIA patients feel in control and it helped them monitor symptoms and disease activity. e-consults were thought to facilitate communication with physicians. The young adults considered both the website and the online portal as feasible, but they also had valuable suggestions to improve accessibility and use. Based on these findings, a news and event section was added on the website and a direct link was made to a discussion board and social media. To provide and support health information, the website is actively used in daily care. Considering the online portal, the use of self-monitoring tools and e-consult can be stimulated if there is direct linkage to treatment and feedback from the multidisciplinary team

    The use of a radio-tracer of portal circulation through the intestine, should prevent cruel punctures in the portal-vein or spleen as it is usually the case with traditional methods in the study of portal-system. The absorption of I-131 and Tc-99m, previously cheked in rabbits presented similar results in dogs. The time of circulation between terminal large-intestine and the liver (t-RF) was determined by external counting at hepatic level by recording radioactivity variation-time. In healthy animals the t-RF was from 20to 60 seconds, with average time of 42 seconds. In 2 animals with partial binding of portal-vein the t-RF went up to 110 and 120 seconds. (Author) [pt

    The detection of the unauthorized movement of radioactive materials is one of the most effective nonproliferation measures. Automatic special nuclear material (SNM) portal monitors are designed to detect this unauthorized movement and are an important part of the safeguard systems at US nuclear facilities. SNM portals differ from contamination monitors because they are designed to have high sensitivity for the low energy gamma-rays associated with highly enriched uranium (HEU) and plutonium. These instruments are now being installed at international borders to prevent the spread of radioactive contamination an SNM. In this paper the parameters important to evaluating radiation portal monitors are discussed. (author)

    Use of an Internet portal to refill medicines positively affects medication adherence among English-speakers. No prior studies, however, have specifically examined the relationship between Internet refills and medication adherence among patients who are limited English proficient (LEP). (1) Examine the relationship between Internet medication refill system use and medication adherence among linguistically diverse patients with chronic conditions and (2) compare this relationship between LEP and English-proficient (EP) patients. We analyzed 2013-2014 cross-sectional data from 509 surveyed adults in the Group Health Cooperative. Surveys were merged with plan enrollment, claims data, and electronic medical records. Medication adherence was calculated by the "Continuous Measure of Medication Gaps" (CMG) method. For Internet refill system use, patients were asked, "Have you used the health systems Internet site to refill any medications in the last 12 months?" LEP status was captured in the electronic medical record by a non-English primary language and a claims record of interpreter use in at least one clinical encounter between 2005 and 2012. We used multivariate linear regression models to examine Internet refill system use and medication adherence and compared the association between LEP and EP patients. Three hundred eighty-four patients (75%) had a calculable CMG: 134 EP and 250 LEP in the adherence analyses. In unadjusted analyses, LEP patients had lower use of the Internet refill system (p < .001) and lower adherence versus the EP group (p < .001). In multivariate analyses, LEP status (β = - 0.022, p = .047) was negatively associated with adherence, while use of the Internet refill system (β = 0.030, p = .002) was positively associated. In stratified models, use of Internet refills was positively associated with adherence, even when examining LEP (β = 0.029, p = .003) and EP patients (β = 0.027, p = .049) separately

    We find that on average an announcement of rising unemployment is 'good news' for stocks during economic expansions and 'bad news' during economic contractions. Thus stock prices usually increase on news of rising unemployment, since the economy is usually in an expansion phase. We provide an explanation for this phenomenon. Unemployment news bundles two primitive types of information relevant for valuing stocks: information about future interest rates and future corporate earnings and divide...

  16. When Sound Bites Become the News: a Case Study on Manufacturing News in Croatia

    2017-06-01

    Full Text Available Media environment is rapidly changing and facing a widespread crisis in journalism. It is followed by the decline of audience trust and increasing market pressures. The main goal is to win the audience’s attention, very often by creating drama and producing ‘conflict’. The news is not based on something that really happened and that is relevant, but it is more often manufactured or artificially produced. In this case study we explore the curious life cycle of a sound bite from a passing remark by the then Croatian Prime Minister Zoran Milanović’s to the headlines, discussions and extensive reports which developed over the course of several days. This example shows how news could be manufactured and content blurred when it is built around a fragment without providing the context, in this case a political quote. For several days, politicians, experts, war veterans, but also ordinary citizens were involved in the manufactured news story without making a reference to the context. Consequently, the democratic debate was avoided. Drawing on a discussion of news fragmentation as isolation from context, we show that in this case, news values (what news is are increasingly blurred, preventing the news from becoming the source of information and discussion of the country’s key issues.

  17. Pathology of idiopathic non-cirrhotic portal hypertension.

    Science.gov (United States)

    Guido, Maria; Sarcognato, Samantha; Sacchi, Diana; Colloredo, Guido

    2018-04-12

    Idiopathic non-cirrhotic portal hypertension is an under-recognized vascular liver disease of unknown etiology, characterized by clinical signs of portal hypertension in the absence of cirrhosis. By definition, any disorder known to cause portal hypertension in the absence of cirrhosis and any cause of chronic liver disease must be excluded to make a diagnosis of idiopathic non-cirrhotic portal hypertension. However, the diagnosis is often difficult because the disease resembles cirrhosis and there is no gold standard test. Liver biopsy is an essential tool: it is able to exclude cirrhosis and other causes of portal hypertension and it allows the identification of the characteristic lesions. Nonetheless, the histological diagnosis of idiopathic non-cirrhotic portal hypertension is not always straightforward, in particular by needle biopsy samples, because there is no pathognomonic lesion, but rather a variety of vascular changes which are unevenly distributed, very subtle, and not all necessarily identified in a single specimen. Pathologists should be able to recognize several patterns of injury, involving portal/periportal areas as well as parenchymal structures.The histological features of idiopathic non-cirrhotic portal hypertension are described in this review, focusing on their interpretation in needle biopsy specimens.

O artigo mostra que implantando o portal nesse contexto a empresa avança consideravelmente com relação à gestão da informação. Para tal o artigo foca na descrição dos aspectos positivos que decorrem da implantação de um portal de intranet / extranet nesse contexto, i.e. integração com Windows e com o Office ou outras aplicações de escritório; controle de edição compartilhada (com check-in e check-out; acesso universal ao acervo pela internet; uso de metadados e automação de processos via workflow.The article shows that it is possible to implement a corporate portal using open source software, in an integrated manner with the proprietary MS Windows environment. As it is the real scenario in the vast majority of businesses and organizations today, a portal that meets these specific requirements is highly representative, mainly because MS Windows integration in the client environment (not in the server is not trivial for an open source portal. The paper shows that, by deploying a portal in this context the company considerably moves forward regarding information management. To show this, the article focuses on the key positive aspects arising from the deployment of a intranet / extranet portal in that context, i.e., MS Windows integration; editing with MS Office or other similar

    US states have begun to legalize marijuana for recreational use. In the absence of clear scientific evidence regarding the likely public health consequences of legalization, it is important to understand how the risks and benefits of this policy are being discussed in the national dialogue. To assess the public discourse on recreational marijuana policy, we assessed the volume and content of US news media coverage of the topic. We analyzed the content of a 20% random sample of news stories published/aired in high circulation/viewership print, television, and Internet news sources from 2010 to 2014 (N=610). News media coverage of recreational marijuana policy was heavily concentrated in news outlets from the four states (AK, CO, OR, WA) and DC that legalized marijuana for recreational use during the study period. Overall, 53% of news stories mentioned pro-legalization arguments and 47% mentioned anti-legalization arguments. The most frequent pro-legalization arguments posited that legalization would reduce criminal justice involvement/costs (20% of news stories) and increase tax revenue (19%). Anti-legalization arguments centered on adverse public health consequences, such as detriments to youth health and well-being (22%) and marijuana-impaired driving (6%). Some evidence-informed public health regulatory options, like marketing and packaging restrictions, were mentioned in 5% of news stories or fewer. As additional states continue to debate legalization of marijuana for recreational use, it is critical for the public health community to develop communication strategies that accurately convey the rapidly evolving research evidence regarding recreational marijuana policy.

    Idiopathic noncirrhotic portal hypertension is a poorly defined clinical condition of unknown etiology. Patients present with signs and symptoms of portal hypertension without evidence of cirrhosis. The disease course appears to be indolent and benign with an overall better outcome than cirrhosis, as long as the complications of portal hypertension are properly managed. This condition has been recognized in different parts of the world in diverse ethnic groups with variable risk factors, resulting in numerous terminologies and lack of standardized diagnostic criteria. Therefore, although the diagnosis of idiopathic noncirrhotic portal hypertension requires clinical exclusion of other conditions that can cause portal hypertension and histopathologic confirmation, this entity is under-recognized clinically as well as pathologically. Recent studies have demonstrated that variable histopathologic entities with different terms likely represent a histologic spectrum of a single entity of which obliterative portal venopathy might be an underlying pathogenesis. This perception calls for standardization of the nomenclature and formulation of widely accepted diagnostic criteria, which will facilitate easier recognition of this disorder and will highlight awareness of this entity.

This system utilized a recommender system to provide only relevant news to the user. This research proposed a system architecture that used vector space model, and Rocchio relevance feedback to provide specific news recommendation to user’s feedback. The results are that the proposed system architecture can achieve the goal by using five levels of feedback from the user. However, the time needed to gather news is increasing exponentially in line with the number of terms gathered from articles.

    Portal hypertension is a common pathology in childhood and one of its most common causes is cavernomatosis of the portal vein. This obstruction causes hemodynamic changes which lead to splenomegaly and collateral circulation. Esophageal varices are one of the most important sequelae, which endanger the patient's life because of a bleeding tendency. Ecosonography helps to detect the thickening of the lesser omentum vis a vis the aortic diameter, caused by the collateral circulation. We studied 15 children presenting with portal hypertension resulting from portal vein cavernomatosis; we performed an upper GI endoscopy and abdominal ecosonography. The endoscopy revealed grade II esophageal varices in 20% of cases, the remaining 80% had grade III and grade IV. Ecosonography revealed an increased lesser omentum/aorta ratio in children with portal hypertension, compared to controls (p portal hypertension.

    Full Text Available In tourism, as in any other industry, information plays an extremely important role. If until now some years planning a holiday was made only at the offices of travel agencies, now we have the alternative internet. The multitude of portals, last minute offers, early booking and city breaks can help plan a much dreamed vacation. All at a distance from a few clicks. You just need to be patient and willing to read a lot because the forums are filled with opinions and comments of those who have been in one place or another. Internal and external tourism recorded significant increases amid constant existence of an increasingly number of tourists and diversification of existing offers. According, investigations, this growth is the Internet, which managed to turn aggressive competition and prices. Based on various information about all destinations, routes and accommodation, tourists are increasingly demanding internet site allowing them to "visualize" holiday, and thus obliges travel agencies and hoteliers to provide better service better even at lower prices. This paper highlights the changes made in the tourism sector with remarkable developments of the computer era, and the Internet in particular.

    The term idiopathic noncirrhotic portal hypertension (INCPH) has been recently proposed to replace terms, such as hepatoportal sclerosis, idiopathic portal hypertension, incomplete septal cirrhosis, and nodular regenerative hyperplasia, used to describe patients with a hepatic presinusoidal cause of portal hypertension of unknown etiology, characterized by features of portal hypertension (esophageal varices, nonmalignant ascites, porto-venous collaterals), splenomegaly, patent portal, and hepatic veins and no clinical and histological signs of cirrhosis. Physicians should learn to look for this condition in a number of clinical settings, including cryptogenic cirrhosis, a disease known to be associated with INCPH, drug administration, and even chronic alterations in liver function tests. Once INCPH is clinically suspected, liver histology becomes mandatory for the correct diagnosis. However, pathologists should be familiar with the histological features of INCPH, especially in cases in which histology is not only requested to exclude liver cirrhosis.

    Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal interactions may contain the ingredients for a strong first-order electroweak phase transition as well as new CP-violating interactions as needed for electroweak baryogenesis. These interactions may also allow for a viable dark matter candidate. We survey the opportunities for probing the Higgs portal as it relates to these questions in cosmology at the LHC and possible future colliders.

    Even democracies endowed with the most active free press struggle to maintain diversity of news coverage. Consolidation and market forces may cause only a few dominant players to control the news cycle. Editorial policies may be biased by corporate ownership relations, narrowing news coverage and focus. To an increasing degree this problem also applies to social media news distribution, since it is subject to the same socio-economic drivers. To study the effects of consolidation and ownership on news diversity, we model the diversity of Chilean coverage on the basis of ownership records and social media data. We create similarity networks of news outlets on the basis of their ownership and the topics they cover. We then examine the relationships between the topology of ownership networks and content similarity to characterize how ownership affects news coverage. A network analysis reveals that Chilean media is highly concentrated both in terms of ownership as well as in terms of topics covered. Our method can be used to determine which groups of outlets and ownership exert the greatest influence on news coverage.

    Splenoportography has been proved as a useful method for the evaluation of circulatory disturbances in portal hypertension. Authors analyzed the various aspects of these disturbance on splenoportography in 22 cases that was performed under the clinical suspicion of portal hypertension during recent 6 years, from May, 1976 to July 1982 at the Department of Radiology, National Medical Center. The results were as follows: 1. Liver cirrhosis was the most frequent cause of intrahepatic obstruction type in portal hypertension (86%). 2. The portal pressure was more than 400 mmH{sub 2}0 in 67% of the cases (range; 300-540 mmH{sub 2}0). 3. In the majority of the cases, the higher the portal pressure was, the more dilated splenic and portal veins were. The diameter of portal vein was more than 15 mm in 79%, more than 21 mm in 47% of the cases (range; 10-26 mm). The diameter of splenic vein was more than 15 mm in 48% of the cases (range; 7-23 mm). Especially the diameter of splenic vein was larger than that of portal vein in 20% of the cases. 4. There was no definite correlation between the development of collateral circulation and the diameter of splenic and portal veins. 5. The filling of collateral circulation was definite sign of portal hypertension, though not regular. In portal hypertension, the collateral circulation was formed via coronary vein (91%), short gastric vein (64%), inferior mesenteric vein (36%). 6. Splenic-hilum time was delayed in 64% of the cases. Intrahepatic portal vein emptying time was more than 6 seconds in all the cases. 7. Most of the cases (91%) could be diagnosed as portal hypertension with vasculogram and hepatogram.

The concept of experience according to Schmitt (1999 and Hirschman and Holbrook (1982 was used wherein it is considered to be an individual, emotional and meaningful occurrence based on the interaction with a stimulus. Focus on tourism portals was due to these two circumstances. Tourism has had a significant growth over the last few years and Brazil has a large potential that is not yet well exploited Tourism portals are seen in literature as forms of self-presentation, carefully constructed by localities and once elaborated, they can have an impact on travel and its relation to the economy of the tourist locality. The method adopted was of an exploratory nature using qualitative investigation procedures consisting of desk research and content analysis of portals selected from the predefined dimensions of experience and based on a review of literature related to the subject. It was found that the portals investigated did not yet explore the offer of experience in the form proposed by the theory investigated.Este artículo investiga, en la perspectiva del especialista, cómo dimensiones teóricas de la experiencia están siendo utilizadas en portales gubernamentales de turismo.

    The aims of this cross-sectional study were to examine the associations of suicidal ideation and attempt with Internet addiction and Internet activities in a large representative Taiwanese adolescent population. 9510 adolescent students aged 12-18 years were selected using a stratified random sampling strategy in southern Taiwan and completed the questionnaires. The five questions from the Kiddie Schedule for Affective Disorders and Schizophrenia were used to inquire as to the participants' suicidal ideation and attempt in the past one month. The Chen Internet Addiction Scale was used to assess participants' Internet addiction. The kinds of Internet activities that the adolescents participated in were also recorded. The associations of suicidal ideation and attempt with Internet addiction and Internet activities were examined using logistic regression analysis to control for the effects of demographic characteristics, depression, family support and self-esteem. After controlling for the effects of demographic characteristics, depression, family support and self-esteem, Internet addiction was significantly associated with suicidal ideation and suicidal attempt. Online gaming, MSN, online searching for information, and online studying were associated with an increased risk of suicidal ideation. While online gaming, chatting, watching movies, shopping, and gambling were associated with an increased risk of suicidal attempt, watching online news was associated with a reduced risk of suicidal attempt. The results of this study indicated that adolescents with Internet addiction have higher risks of suicidal ideation and attempt than those without. Meanwhile, different kinds of Internet activities have various associations with the risks of suicidal ideation and attempt. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available ABSTRACT: Pulsed Doppler ultrasound was used to evaluate portal blood flow, portal velocity and portal congestion index in 24 healthy sheep divided into groups (lambs, yearlings and ewes, according to age. Measurements were performed at the 11th right intercostal space using ideal insonation angle and uniform insonation method. Mean values obtained in each group were compared with one-way ANOVA, followed by Tukey post-hoc test. Portal velocity and portal blood flow were statistically similar between the groups (P>0.05. Mean portal velocity were 17.75; 17.13 and 16.75; while mean portal blood flow were 26.65; 31.04 and 24.32 for lambs, yearlings and ewes, respectively. Portal congestion index was statistically distinct between the groups and values for lambs, yearlings and ewes were 0.009; 0.058 and 0.09, respectively (P<0.01. Statistical differences were observed in portal vein diameter, portal vein area and portal congestion index between the groups, presumably due to influence of weight and not to age.

    The FP7 project "Climate Information Portal for Copernicus" (CLIPC) is developing a demonstration portal for the Copernicus Climate Change Service (C3S). This project is one of a suite of FP7 research activities which are administratively independent of Copernicus, focussed on creating the technical and scientific building blocks needed for the service. It is to be expected that at EGU 2015 there will be many presentations describing portals delivering new and innovative ranges of services. It would be unwise to seek to replace all this creative activity with a single portal -- instead CLIPC is designing a portal to make distributed resources more accessible through flexible discovery systems. CLIPC needs to deliver more than a directory of resources: resources need to be presented in common protocols so that users can access multiple datasets. More information about the project objectives is available at www.clipc.eu. The gulf between the climate science communities and the end user communities is a central challenge being addressed in the project. It is important to understand that there is significant diversity and multiple communication barriers within these two sets of communities as well as between them. The CLIPC services must presentation will provide a review of progress towards this ambitious goal, through a discussion of user requirements activities, an overview of the proposed architecture, work on assessing and adjusting model biasses, and a discussion of the climate impact indicators which will be provided through the portal. When looking at the usability of data for the various users, CLIPC will implement a set of services functioning as a "knowledge base" supplying information to users about the data, including definitions of terminology used, quality of datasets, versioning, and user annotations.

Business success, research and study rely on intense usage of the Internet, doing most of the ac tivities based on information gathered at the Internet and using diverse kind of services available. The recent development in devices and services, either for computational or mobile operations, has revealed a diversity of paths for the Internet to have impact in our lives, either professional or personal. Without notice, every activity we do is becoming somehow connected to the web in multiple forms that can range from the search of information, the communication between people and information storage at the cloud. Everything seems to be so useful and so destined to promote our life and supply our needs for work, learning or recreation activities. As for the social aspects, Internet has a multitude of opportunities to communicate, to share ideas and to get feedback or news, as it happens, with online newspapers, the blogosphere and social networks. With this pervasive and sometimes implicit integration of the Internet in our lives, we are migrating from traditional way of life to an Internet supported life style with many daily Internet based activities executed by each human being. However, despite this movement of almost putting us in the innards of Internet, we didn’t yet notice a structural change in such infrastructure to cope with our human nature and, in particular, with the way we perceive and feel the world.

    Full Text Available Abstract Background The Neighborhood Environment Walkability Scale (NEWS and its abbreviated form (NEWS-A assess perceived environmental attributes believed to influence physical activity. A multilevel confirmatory factor analysis (MCFA conducted on a sample from Seattle, WA showed that, at the respondent level, the factor-analyzable items of the NEWS and NEWS-A measured 11 and 10 constructs of perceived neighborhood environment, respectively. At the census blockgroup (used by the US Census Bureau as a subunit of census tracts level, the MCFA yielded five factors for both NEWS and NEWS-A. The aim of this study was to cross-validate the individual- and blockgroup-level measurement models of the NEWS and NEWS-A in a geographical location and population different from those used in the original validation study. Methods A sample of 912 adults was recruited from 16 selected neighborhoods (116 census blockgroups in the Baltimore, MD region. Neighborhoods were stratified according to their socio-economic status and transport-related walkability level measured using Geographic Information Systems. Participants self-completed the NEWS. MCFA was used to cross-validate the individual- and blockgroup-level measurement models of the NEWS and NEWS-A. Results The data provided sufficient support for the factorial validity of the original individual-level measurement models, which consisted of 11 (NEWS and 10 (NEWS-A correlated factors. The original blockgroup-level measurement model of the NEWS and NEWS-A showed poor fit to the data and required substantial modifications. These included the combining of aspects of building aesthetics with safety from crime into one factor; the separation of natural aesthetics and building aesthetics into two factors; and for the NEWS-A, the separation of presence of sidewalks/walking routes from other infrastructure for walking. Conclusion This study provided support for the generalizability of the individual

    The Internet, the largest network of connected computers, provides immediate, dynamic, and downloadable information. By re-architecturing the work place and becoming familiar with Internet resources, pediatric surgeons have anticipated the informatics capabilities of this computer-based technology creating a new vision of work and organization in such areas as patient care, teaching, and research. This review aims to highlight how Internet navigational technology can be a useful educational resource in pediatric surgery, examines web pages of interest, and defines ideas of network communication. Basic Internet resources are electronic mail, discussion groups, file transfer, and the Worldwide Web (WWW). Electronic mailing is the most useful resource extending the avenue of learning to an international audience through news or list-servers groups. Pediatric Surgery List Server, the most popular discussion group, is a constant forum for exchange of ideas, difficult cases, consensus on management, and development of our specialty. The WWW provides an all-in-one medium of text, image, sound, and video. Associations, departments, educational sites, organizations, peer-reviewed scientific journals and Medline database web pages of prime interest to pediatric surgeons have been developing at an amazing pace. Future developments of technological advance nurturing our specialty will consist of online journals, telemedicine, international chatting, computer-based training for surgical education, and centralization of cyberspace information into database search sites.

    AIM: To study the blood-brain barrier integrity in prehepatic portal hypertensive rats induced by partial portal vein ligation, at 14 and 40 d after ligation when portal pressure is spontaneously normalized. METHODS: Adult male Wistar rats were divided into four groups: Group I: Sham14d , sham operated; Group II: PH14d , portal vein stenosis; (both groups were used 14 days after surgery); Group III: Sham40d, Sham operated and Group IV: PH40d Portal vein stenosis (Groups II and IV used 40 d after surgery). Plasma ammonia, plasma and cerebrospinal fluid protein and liver enzymes concentrations were determined. Trypan and Evans blue dyes, systemically injected, were investigated in hippocampus to study blood-brain barrier integrity. Portal pressure was periodically recorded. RESULTS: Forty days after stricture, portal pressure was normalized, plasma ammonia was moderately high, and both dyes were absent in central nervous system parenchyma. All other parameters were reestablished. When portal pressure was normalized and ammonia level was lowered, but not normal, the altered integrity of blood-brain barrier becomes reestablished. CONCLUSION: The impairment of blood-brain barrier and subsequent normalization could be a mechanism involved in hepatic encephalopathy reversibility. Hemodynamic changes and ammonia could trigger blood-brain barrier alterations and its reestablishment. PMID:16552803

    Full Text Available The article shows that it is possible to implement a corporate portal using open source software, in an integrated manner with the proprietary MS Windows environment. As it is the real scenario in the vast majority of businesses and organizations today, a portal that meets these specific requirements is highly representative, mainly because MS Windows integration in the client environment (not in the server is not trivial for an open source portal. The paper shows that, by deploying a portal in this context the company considerably moves forward regarding information management. To show this, the article focuses on the key positive aspects arising from the deployment of a intranet / extranet portal in that context, i.e., MS Windows integration; editing with MS Office or other similar applications; shared editing control (with check-in and check-out; universal web access; and the use of metadata and workflow.

    Patients are being encouraged to go online to obtain health information and interact with their health care systems. However, a 2014 survey found that less than 60% of American adults aged 65 and older use the Internet, with much lower usage among black and Latino seniors compared with non-Hispanic white seniors, and among older versus younger seniors. Our aims were to (1) identify race/ethnic and age cohort disparities among seniors in use of the health plan's patient portal, (2) determine whether race/ethnic and age cohort disparities exist in access to digital devices and preferences for using email- and Web-based modalities to interact with the health care system, (3) assess whether observed disparities in preferences and patient portal use are due simply to barriers to access and inability to use the Internet, and (4) learn whether older adults not currently using the health plan's patient portal or website have a potential interest in doing so in the future and what kind of support might be best suited to help them. We conducted two studies of seniors aged 65-79 years. First, we used administrative data about patient portal account status and utilization in 2013 for a large cohort of English-speaking non-Hispanic white (n=183,565), black (n=16,898), Latino (n=12,409), Filipino (n=11,896), and Chinese (n=6314) members of the Kaiser Permanente Northern California health plan. Second, we used data from a mailed survey conducted in 2013-2014 with a stratified random sample of this population (final sample: 849 non-Hispanic white, 567 black, 653 Latino, 219 Filipino, and 314 Chinese). These data were used to examine race/ethnic and age disparities in patient portal use and readiness and preferences for using digital communication for health-related purposes. Adults aged 70-74 and 75-79 were significantly less likely than 65-69 year olds to be registered to use the patient portal, and among those registered, to have used the portal to send messages, view lab test

    Electronic, or web-based, patient portals can improve patient satisfaction, engagement and health outcomes and are becoming more prevalent with the advent of meaningful use incentives. However, adoption rates are low, particularly among vulnerable patient populations, such as those patients who are home-bound with multiple comorbidities. Little is known about how these patients view patient portals or their barriers to using them. To identify barriers to and facilitators of using My HealtheVet (MHV), the United States Department of Veterans Affairs (VA) patient portal, among Veterans using home-based primary care services. Qualitative study using in-depth semi-structured interviews. We conducted a content analysis informed by grounded theory. Fourteen Veterans receiving home-based primary care, surrogates of two of these Veterans, and three home-based primary care (HBPC) staff members. We identified five themes related to the use of MHV: limited knowledge; satisfaction with current HBPC care; limited computer and Internet access; desire to learn more about MHV and its potential use; and value of surrogates acting as intermediaries between Veterans and MHV. Despite their limited knowledge of MHV and computer access, home-bound Veterans are interested in accessing MHV and using it as an additional point of care. Surrogates are also potential users of MHV on behalf of these Veterans and may have different barriers to and benefits from use. © 2014 John Wiley & Sons Ltd.

  13. COM5/443: Health Portals, Search Engines and Intranets: Making order of the chaos - A review article

    Effective use of technology has led to medical advances that have not only extended life expectancy, but also fuelled an increasingly well informed public's desires to expect more and more from today's healthcare providers. A phenomenal amount of medical information is now present, facilitated by the virtually unrestricted ability to publish on the Internet. The WWW grows by roughly a million pages per day with a significant number devoted to some element of healthcare. As a consequence of the web's rapid, chaotic growth, the resulting network of information lacks organisation and structure and the quest for a method of finding relevant and reliable information quickly is spawning the growth of the Internet Portal Sites. The use of intranets confers some degree of organisation, allowing for structured growth of an organisation's web site but the majority of sites are not sheltered within an intranet. Millions of dollars are being invested in researching the technologies powering search engines and well designed portals, in the hope of imposing some kind of order on the existing chaos. The winner will most likely reap huge financial rewards as advertisers climb on board, hoping to gain massive exposure and the public will undoubtedly gain from relevant and timely answers to their searches and queries. Information is a valuable commodity, but the true value is seen only when it is organised into an accessible and useable form. The coming of age of the Internet has heralded radical changes in the fabric and economics of healthcare and as a consequence our expectations from professionals involved in this industry are greatly increased. Although significant challenges need to be overcome, there are huge benefits to be gained for consumers, although it remains to be seen whether the world becomes a more healthy place.

  15. Some thoughts to realignment of PortalU

    2013-01-01

    Environmental information is the basis for improving the environmental situation in the EU. The challenge poses the tailoring of information to a defined group of interest and not only the technical possibility to retrieve the environmental information. Even though, the technical infrastructure for retrieving public environmental information is the first step. Hence, the clear understanding of the needs of the general public is essential for a successful environmental information portal for the interest group ''general public''. What does this mean referring to the German Environmental Information Portal PortalU? Since the launch of PortalU the focus of the portal is set on making available official environmental information especially on German Federal Republic and Federal States level. Currently, information from web pages represents the greatest amount of information. In contrast, information from environmental data catalogs and further data bases represent a smaller amount of information within PortalU. But quantity itself does not tell anything about the demand of a target group. The experience of the last years has shown that environmental interested citizens use mainly general search engines like Google to find information from public environmental web pages. Thus it would be worth thinking about a realignment of PortalU. The idea of a prospective alignment of PortalU is to concentrate on important environmental information, which is not easily found via Google and other general search engines. This information is mainly provided via environmental data catalogs and possibly further data bases. Some thoughts about the potential form and design of a respectively aligned environmental portal are discussed in the paper. (orig.)

    Preduodenal portal vein is a rare anatomical variant which may be one of many anomalies in the neonate with duodenal "atresia." Preduodenal portal vein also may be an occasional finding in an adult undergoing biliary, gastric, or pancreatic surgery. Awareness and recognition of the anomaly are essential for the avoidance of injury during such operations. We report here a symptomless patient whose preduodenal portal vein was discovered at cholecystectomy.

    In 2006, the U.S. Food and Drug Administration licensed a vaccine for the human papillomavirus (HPV) that prevents the strains of HPV that cause 70% of cervical cancers. Within months, many states introduced legislation requiring the vaccine for girls, prompting controversy and heightened political and media attention to the issue. Previous research has shown differences in HPV vaccine awareness by individual-level characteristics such as race/ethnicity, income, and education levels. We examined how individual political orientation and exposure to media coverage can also shape awareness of the vaccine. Using data from a 2009 Internet survey of 1,216 nationally representative adult respondents linked to data on state-specific news coverage, we assessed how political orientation, media exposure, and state political context predicted HPV vaccine awareness. Younger people, women, and those with more education were significantly more likely to be aware of the vaccine. Even after controlling for these characteristics, we found that exposure to news media was associated with higher HPV vaccine awareness. Whereas liberals and conservatives were both more aware of the vaccine compared with moderates, the data are suggestive that liberals were more sensitive to news coverage. These findings suggest that individual-level political identities and their interaction with the informational environment may be important factors to consider in evaluating the determinants of individuals' attitudes and behaviors related to politically charged women's health issues.

    Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

    Use of patient portals may contribute to improved patient health and experiences and better organizational performance. In the Netherlands, patient portals have gained considerable attention in recent years, as evidenced by various policy initiatives and practical efforts directed at developing portals. Due to the fragmented setup of the Dutch healthcare system patient portals that give patients access to information and services from across their providers are developed in inter-organizational collaboration. The objective of this paper is to identify and describe the types of collaborations, or networks, that have been established to develop patient portals in the Netherlands. Understanding the characteristics of these networks as well as the development of their respective portals enables us to assess the enabling and constraining effects of different network types on patient portal initiatives. We used qualitative methods including interview and documents analysis. In a first step, we interviewed eighteen experts and reviewed relevant national policy and strategy documents. Based on this orientation, we selected three networks we deemed to be representative of inter-organizational efforts to develop Dutch patient portals in 2012. In a second step, we interviewed twelve representatives of these patient portal networks and collected documents related to the portals. We applied content analytic techniques to analyze data from the three cases. The three studied networks differed in their number and diversity of actors, the degree to which these actors were mutually dependent, the degree to which network governance was decentralized, and the dynamics of the network structures. We observed that the portals developed in networks displaying the highest degree of these characteristics experienced most difficulties associated with developing patient portals - such as achieving interoperability, successful implementation, regulatory complaisance, and financial

    2011-01-01

    Portal hypertension is a major cause of morbidity and mortality in patients with liver cirrhosis. Intrahepatic vascular resistance due to architectural distortion and intrahepatic vasoconstriction, increased portal blood flow due to splanchnic vasodilatation, and development of collateral circulation have been considered as major factors for the development of portal hypertension. Recently, sinusoidal remodeling and angiogenesis have been focused as potential etiologic factors and various researchers have tried to improve portal hypertension by modulating these new targets. This article reviews potential new treatments in the context of portal hypertension pathophysiology concepts. PMID:25755320

    Investigate the quality of data available on the internet with respect to pain after orthognathic surgery. A careful search was conducted on the Internet in December, 2012. The most accessed websites browsers were employed for research using the terms: "pain" and "orthognathic surgery" together. The first 30 results of each portal were examined, and after applying the exclusion criteria, 29 sites remained. All remaining websites went through an evaluation process with online tools that investigated the quality, level of reading, accessibility, usability and reliability. Assessment criteria outcomes were considered unfavorable. Texts were considered difficult to read with inappropriate language for the general public. The mean global validation for the 29 websites of the LIDA instrument was 65.10, thereby indicating a structure of medium quality. Information about post-orthognathic surgery pain available on the internet is poorly written and unreliable. Therefore, candidates for orthognathic surgery must seek information from specialists who, in turn, should indicate reliable sources.

    2016-06-01

    Although giving bad news at work is a stressful experience, managers are often underprepared for this challenging task. As a solution, we introduce organizational bad news training that integrates (a) principles of delivering bad news from the context of health care (i.e., bad news delivery component), and (b) principles of organizational justice theory (i.e., fairness component). We argue that both the formal and fair delivery of bad news at work can be enhanced with the help of training to mitigate distress both for the messenger and the recipient. We tested the effectiveness of training for the delivery of a layoff as a typical bad news event at work. In 2 studies, we compared the performance of a training group (receiving both components of training) with that of a control group (Study 1, Study 2) and a basics group (receiving the bad news delivery component only; Study 2) during a simulated dismissal notification meeting. In general, the results supported our hypotheses: Training improved the formal delivery of bad news and predicted indicators of procedural fairness during the conversation in both studies. In Study 2, we also considered layoff victims' negativity after the layoff and found that training significantly reduced negative responses. This relationship was fully mediated by layoff victims' fairness perceptions. Despite preparation, however, giving bad news remained a challenging task in both studies. In summary, we recommend that organizations provide managers with organizational bad news training in order to promote professional and fair bad news conversations at work.

    In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59%) had specific training on breaking bad news. 20 doctors (33.90%) were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66%) had a consistent plan for breaking bad news. 57 (96.61%) delivered bad news in a quiet place, 53 (89.83%) ensured no interruptions and enough time, 53 (89.83%) used simple words and 54 (91.53%) checked for understanding and did not rush through the news. 46 doctors (77.97%) allowed relatives to determine patient's knowledge about the disease. There were low rates of specific training in breaking bad news. However, the selected location, the physician's speech and their plan were according to current guidelines.

    In patients with hepatocellular carcinoma (HCC), limited therapeutic options are available for portal hypertension resulted from portal vein tumor thrombus (PVTT). We aimed to determine safety and efficacy of TIPS for treatment of symptomatic portal hypertension in HCC with PVTT. We evaluated clinical characteristics of 95 patients with HCC and PVTT out of 992 patients who underwent TIPS. The primary endpoints included success rate, procedural mortality, serious complications, decrease in portosystemic pressure gradient, and symptom relief. The secondary endpoints included recurrence of portal hypertension, overall survival, adverse events related to treatments for HCC, and quality of life measured by Karnofsky Performance Status Scale (KPS). Success rate of TIPS was 95.8% (91/95), with procedural mortality of 1.1%. Serious complications related to TIPS procedure occurred in 2.1% (2/95) of patients.

    The purpose of this review is to summarize the key findings which prove that the biased perceptions of viewers may provide an inaccurate image of the informational validity of televised news. The news may generate distorted recollections of what occurred in particular reported events if displayed routines influence viewers not to pay attention to the essential features of a narrative. Elaborating on Fiske and Hartley (2010), Zelizer (2010), and Gunter (2015), we indicate that the character of the news setting has altered and individuals' news consumption routines have changed in adapting to media advancements. The news may be undergone at various psychological stages by news publics. Televised news may transmit information undeviatingly to publics that may (not) be committed successfully to memory. Our paper shows that individuals' skills to handle information that is displayed in a linguistic configuration are influenced by their abilities in the utilization of certain symbol systems that are employed to represent notions and meanings. Televised news may shape what individuals grasp, influence their perceptions, convictions, and views regarding prevailing events and matters, and transmit knowledge and interpretation. If news stories can be jotted down in a linguistic style that sidesteps making needless processing demands and captivate news users by facilitating them to make connections with former knowledge, they may be more worthy of note and more edifying. We conclude that news narratives present a cognitive demanding task to individuals, displaying novel information regarding evolving events in a multifarious format. Broadcast news exhibits intricate contents, displaying configurations that employ excessively the cognitive abilities for information processing of viewers.

    Full Text Available The analysis of news in the financial context has gained a prominent interest in the last years. This is because of the possible predictive power of such content especially in terms of associated sentiment/mood. In this paper, we focus on a specific aspect of financial news analysis: how the covered topics modify according to space and time dimensions. To this purpose, we employ a modified version of topic model LDA, the so-called Structural Topic Model (STM, that takes into account covariates as well. Our aim is to study the possible evolution of topics extracted from two well known news archive—Reuters and Bloomberg—and to investigate a causal effect in the diffusion of the news by means of a Granger causality test. Our results show that both the temporal dynamics and the spatial differentiation matter in the news contagion.

    2016-06-01

    Full Text Available In the last couple of decades there has been an unprecedented explosion of news media platforms and formats, as a succession of digital and social media have joined the ranks of legacy media. We live in a ‘hybrid media system’ (Chadwick, 2013, in which people build their cross-media news repertoires from the ensemble of old and new media available. This article presents an innovative mixed-method approach with considerable explanatory power to the exploration of patterns of news media consumption. This approach tailors Q-methodology in the direction of a qualitative study of news consumption, in which a card sorting exercise serves to translate the participants’ news media preferences into a form that enables the researcher to undertake a rigorous factor-analytical construction of their news consumption repertoires. This interpretive, factor-analytical procedure, which results in the building of six audience news repertoires in Denmark, also preserves the qualitative thickness of the participants’ verbal accounts of the communicative figurations of their day-in-the-life with the news media.

    Web browsers have become a major application interface for participating in scientific experiments such as those in magnetic fusion. The recent advances in web technologies motivated the deployment of interactive web applications with rich features. In the scientific world, web applications have been deployed in portal environments. When used in a scientific research environment, such as fusion experiments, web portals can present diverse sources of information in a unified interface. However, the design and development of a scientific web portal has its own challenges. One such challenge is that a web portal needs to be fast and interactive despite the high volume of information and number of tools it presents. Another challenge is that the visual output of the web portal must not be overwhelming to the end users, despite the high volume of data generated by fusion experiments. Therefore, the applications and information should be customizable depending on the needs of end users. In order to meet these challenges, the design and implementation of a web portal needs to support high interactivity and user customization. A web portal has been designed to support the experimental activities of DIII-D researchers worldwide by providing multiple services, such as real-time experiment status monitoring, diagnostic data access and interactive data visualization. The web portal also supports interactive collaborations by providing a collaborative logbook, shared visualization and online instant messaging services. The portal's design utilizes the multi-tier software architecture and has been implemented utilizing web 2.0 technologies, such as AJAX, Django, and Memcached, to develop a highly interactive and customizable user interface.

    To evaluate the effects of combined Rex-bypass shunt and pericardial devascularization on prehepatic portal hypertension secondary to cavernomatous transformation of portal vein (CTPV). Forty-two patients aged from 3 years to 49 years (divided into 3 groups), 26 cases male and 16 female, with prehepatic vascular hepertention were treated with Rex-bypass shunt combined with pericardial devascularization. In each patient, preoperative assessment included ultrasound and computed tomographic angiography of the portal vein and blood analysis. The procedure was Rex-bypass shunt (with or without graft), and patients with moderate or severe gastroesophageal varices required additional paraesophagogastric devascularization. Splenectomy or subtotal splenectomy was performed if combined hypersplenism co-existed. All data were analyzed retrospectively. No intraoperative death occurred, blood routine analysis improved (P portal vein (LPV) significantly increased, the esophageal and gastric varices significantly relieved in 34 patients (P portal hypertension caused by CTPV.

    2015-01-01

    Full Text Available Objective: In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. Materials and Methods: 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Results: Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59% had specific training on breaking bad news. 20 doctors (33.90% were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66% had a consistent plan for breaking bad news. 57 (96.61% delivered bad news in a quiet place, 53 (89.83% ensured no interruptions and enough time, 53 (89.83% used simple words and 54 (91.53% checked for understanding and did not rush through the news. 46 doctors (77.97% allowed relatives to determine patient′s knowledge about the disease. Conclusions: There were low rates of specific training in breaking bad news. However, the selected location, the physician′s speech and their plan were according to current guidelines.

    Full Text Available Online news reading has become a widely popular way to read news articles from news sources around the globe. With the enormous amount of news articles available, users are easily overwhelmed by information of little interest to them. News recommender systems help users manage this flood by recommending articles based on user interests rather than presenting articles in order of their occurrence. We present our research on developing personalized news recommendation system with the help of a popular micro-blogging service, “Twitter.” News articles are ranked based on the popularity of the article identified from Twitter’s public timeline. In addition, users construct profiles based on their interests and news articles are also ranked based on their match to the user profile. By integrating these two approaches, we present a hybrid news recommendation model that recommends interesting news articles to the user based on their popularity as well as their relevance to the user profile.

  16. Delivering bad news in emergency care medicine.

    Science.gov (United States)

    Maynard, Douglas W

    2017-01-01

    Forecasting is a strategy for delivering bad news and is compared to two other strategies, stalling and being blunt. Forecasting provides some warning that bad news is forthcoming without keeping the recipient in a state of indefinite suspense (stalling) or conveying the news abruptly (being blunt). Forecasting appears to be more effective than stalling or being blunt in helping a recipient to "realize" the bad news because it involves the deliverer and recipient in a particular social relation. The deliverer of bad news initiates the telling by giving an advance indication of the bad news to come; this allows the recipient to calculate the news in advance of its final presentation, when the deliverer confirms what the recipient has been led to anticipate. Thus, realization of bad news emerges from intimate collaboration, whereas stalling and being blunt require recipients to apprehend the news in a social vacuum. Exacerbating disruption to recipients' everyday world, stalling and being blunt increase the probability of misapprehension (denying, blaming, taking the situation as a joke, etc.) and thereby inhibit rather than facilitate realization. Particular attention is paid to the "perspective display sequence", a particular forecasting strategy that enables both confirming the recipient's perspective and using that perspective to affirm the clinical news. An example from acute or emergency medicine is examined at the close of the paper.

    Idiopathic non-cirrhotic portal hypertension is a rare disease of unknown etiology. Patients with idiopathic non-cirrhotic portal hypertension have an increased risk of developing portal vein thrombosis and this is especially prevalent when HIV is also present. We describe a unique case of a patient with idiopathic non-cirrhotic portal hypertension associated to HIV, who developed acute portal vein thrombosis that despite anticoagulation transformed in portal cavernoma and disappeared completely after five years of follow-up on continuous anticoagulation.

  18. User Experience Design in Professional Map-Based Geo-Portals

    Directory of Open Access Journals (Sweden)

    Bastian Zimmer

    2013-10-01

    Full Text Available We have recently been witnessing the growing establishment of map-centered web-based geo-portals on national, regional and local levels. However, a particular issue with these geo-portals is that each instance has been implemented in different ways in terms of design, usability, functionality, interaction possibilities, map size and symbologies. In this paper, we try to tackle these shortcomings by analyzing and formalizing the requirements for map-based geo-portals in a user experience based approach. First, we propose a holistic definition the term of a “geo-portal”. Then, we present our approach to user experience design for map-based geo-portals by defining the functional requirements of a geo-portal, by analyzing previous geo-portal developments, by distilling the results of our empirical user study to perform practically-oriented user requirements, and finally by establishing a set of user experience design guidelines for the creation of map-based geo-portals. These design guidelines have been extracted for each of the main components of a geo-portal, i.e., the map, the search dialogue, the presentation of the search results, symbologies, and other aspects. These guidelines shall constitute the basis for future geo-portal developments to achieve standardization in the user-experience design of map-based geo-portals.

    This observation illustrates how difficult it is to interpret the intravascular signal observed with MRI in cases of portal hypertension. A signal occupying the entire lumen of the portal trunk and branches can be seen, which is constantly observed in the axial as well as coronal planes in the 3 series studied. It is hypointense relative to the liver on T1-weighted images, hyperintense on T2-weighted images: this appearance therefore perfectly mimicks portal thrombosis. Ultrasound combined with pulsed Doppler demonstrates the stagnant blood within the patent portal system. This kind of artifact, which is produced by a very slow flow or even by the standstill of flow, is much more difficult to recognize than the common flow artifacts; the criteria put forward by various authors to distinguish between artifacts and thrombosis are of no avail in this case. Examinations must able to confirm or rule out portal thrombosis in the case of portal hypertension with deceleration of flow. In practice, ultrasound studies, combined with pulsed Doppler in the best cases, is therefore indicated as a first-intension technique [fr

    Splanchnic and systemic low-grade inflammation has been proposed to be a consequence of long-term prehepatic portal hypertension. This experimental model causes minimal alternations in the liver, thus making a more selective study possible for the pathological changes characteristic of prehepatic portal hypertension. Low-grade splanchnic inflammation after long-term triple partial portal vein ligation could be associated with liver steatosis and portal hypertensive intestinal vasculopathy. In fact, we have previously shown that prehepatic portal hypertension in the rat induces liver steatosis and changes in lipid and carbohydrate metabolism similar to those produced in chronic inflammatory conditions described in metabolic syndrome in humans. Dysbiosis and bacterial translocation in this experimental model suggest the existence of a portal hypertensive intestinal microbiome implicated in both the splanchnic and systemic alterations related to prehepatic portal hypertension. Among the systemic impairments, aortopathy characterized by oxidative stress, increased levels of proinflammatory cytokines and profibrogenic mediators stand out. In this experimental model of long-term triple portal vein ligated-rats, the abdominal aortic proinflammatory response could be attributed to oxidative stress. Thus, the increased aortic reduced-nicotinamide-adenine dinucleotide phosphate [NAD(P)H] oxidase activity could be associated with reactive oxygen species production and promote aortic inflammation. Also, oxidative stress mediated by NAD(P)H oxidase has been associated with risk factors for inflammation and atherosclerosis. The splanchnic and systemic pathology that is produced in the long term after triple partial portal vein ligation in the rat reinforces the validity of this experimental model to study the chronic low-grade inflammatory response induced by prehepatic portal hypertension.

    Portal hypertension is a major pathophysiology in patients with cirrhosis. Portal pressure is the gold standard to evaluate the severity of portal hypertension, and radiological intervention is the only procedure for pressure measurement. Ultrasound (US) is a simple and noninvasive imaging modality available worldwide. B-mode imaging allows broad applications for patients to detect and characterize chronic liver diseases and focal hepatic lesions. The Doppler technique offers real-time observation of blood flow with qualitative and quantitative assessments, and the application of microbubble-based contrast agents has improved the detectability of peripheral blood flow. In addition, elastography for the liver and spleen covers a wider field beyond the original purpose of fibrosis assessment. These developments enhance the practical use of US in the evaluation of portal hemodynamic abnormalities. This article reviews the recent progress of US in the assessment of portal hypertension.

    Patient portals have the potential to support self-management for chronic diseases and improve health outcomes. With the rapid rise in adoption of patient portals spurred by meaningful use incentives among safety net health systems (a health system or hospital providing a significant level of care to low-income, uninsured, and vulnerable populations), it is important to understand the readiness and willingness of patients and caregivers in safety net settings to access their personal health records online. To explore patient and caregiver perspectives on online patient portal use before its implementation at San Francisco General Hospital, a safety net hospital. We conducted 16 in-depth interviews with chronic disease patients and caregivers who expressed interest in using the Internet to manage their health. Discussions focused on health care experiences, technology use, and interest in using an online portal to manage health tasks. We used open coding to categorize all the barriers and facilitators to portal use, followed by a second round of coding that compared the categories to previously published findings. In secondary analyses, we also examined specific barriers among 2 subgroups: those with limited health literacy and caregivers. We interviewed 11 patients and 5 caregivers. Patients were predominantly male (82%, 9/11) and African American (45%, 5/11). All patients had been diagnosed with diabetes and the majority had limited health literacy (73%, 8/11). The majority of caregivers were female (80%, 4/5), African American (60%, 3/5), caregivers of individuals with diabetes (60%, 3/5), and had adequate health literacy (60%, 3/5). A total of 88% (14/16) of participants reported interest in using the portal after viewing a prototype. Major perceived barriers included security concerns, lack of technical skills/interest, and preference for in-person communication. Facilitators to portal use included convenience, health monitoring, and improvements in patient

    2016-01-01

    Background Patients are being encouraged to go online to obtain health information and interact with their health care systems. However, a 2014 survey found that less than 60% of American adults aged 65 and older use the Internet, with much lower usage among black and Latino seniors compared with non-Hispanic white seniors, and among older versus younger seniors. Objective Our aims were to (1) identify race/ethnic and age cohort disparities among seniors in use of the health plan’s patient portal, (2) determine whether race/ethnic and age cohort disparities exist in access to digital devices and preferences for using email- and Web-based modalities to interact with the health care system, (3) assess whether observed disparities in preferences and patient portal use are due simply to barriers to access and inability to use the Internet, and (4) learn whether older adults not currently using the health plan’s patient portal or website have a potential interest in doing so in the future and what kind of support might be best suited to help them. Methods We conducted two studies of seniors aged 65-79 years. First, we used administrative data about patient portal account status and utilization in 2013 for a large cohort of English-speaking non-Hispanic white (n=183,565), black (n=16,898), Latino (n=12,409), Filipino (n=11,896), and Chinese (n=6314) members of the Kaiser Permanente Northern California health plan. Second, we used data from a mailed survey conducted in 2013-2014 with a stratified random sample of this population (final sample: 849 non-Hispanic white, 567 black, 653 Latino, 219 Filipino, and 314 Chinese). These data were used to examine race/ethnic and age disparities in patient portal use and readiness and preferences for using digital communication for health-related purposes. Results Adults aged 70-74 and 75-79 were significantly less likely than 65-69 year olds to be registered to use the patient portal, and among those registered, to have used the

    Full Text Available The theory of creative cycling emerged from my PhD study of news professionals in Norway. The study was carried out according to classic grounded theory principles (Glaser and Strauss 1967, Glaser 1978, 1998, 2001, 2005, and the area of interest was the performance of news journalism in the multimedia age. The theory runs counter to widespread tendencies of industrial age thinking in news media. It emphasizes news professionals’ search for meaning in their daily work, and suggests that their main concern is self-fulfillment through original contribution. The dilemma and resolution, creative cycling, is a basic social process continuously going within inner and outer framings. It consists of three interrelated dimensions: productive processing, breaks and shifts and inspirational looping.

    Each exercise device on the International Space Station (ISS) has a unique, customized software system interface with unique layouts / hierarchy, and operational principles that require significant crew training. Furthermore, the software programs are not adaptable and provide no real-time feedback or motivation to enhance the exercise experience and/or prevent injuries. Additionally, the graphical user interfaces (GUI) of these systems present information through multiple layers resulting in difficulty navigating to the desired screens and functions. These limitations of current exercise device GUI's lead to increased crew time spent on initiating, loading, performing exercises, logging data and exiting the system. To address these limitations a Next Generation One Portal (NextGen One Portal) Crew Countermeasure System (CMS) was developed, which utilizes the latest industry guidelines in GUI designs to provide an intuitive ease of use approach (i.e., 80% of the functionality gained within 5-10 minutes of initial use without/limited formal training required). This is accomplished by providing a consistent interface using common software to reduce crew training, increase efficiency & user satisfaction while also reducing development & maintenance costs. Results from the usability evaluations showed the NextGen One Portal UI having greater efficiency, learnability, memorability, usability and overall user experience than the current Advanced Resistive Exercise Device (ARED) UI used by astronauts on ISS. Specifically, the design of the One-Portal UI as an app interface similar to those found on the Apple and Google's App Store, assisted many of the participants in grasping the concepts of the interface with minimum training. Although the NextGen One-Portal UI was shown to be an overall better interface, observations by the test facilitators noted specific exercise tasks appeared to have a significant impact on the NextGen One-Portal UI efficiency.

    The Paleontology Portal website provides a central, interactive entry point to high-quality North American paleontology resources on the Internet for multiple audiences: the research community, government and industry, K-16 students, and the general public. The Portal successfully blends research and education, pulling together information with reviewed and annotated website links for a wide variety of informal learners. Using web-based technology and relational databases, users can explore an interactive map and associated stratigraphic column to access information about particular geographic regions, geologic time periods, depositional environments, and representative taxa. Users are also able to search multiple museum collection databases using a single query form of their own design. Other features include highlights of famous fossil sites and assemblages and a fossil image gallery. Throughout the site, users find images and links to information specific to each time period or geographic region, including current research projects and publications, websites, on-line exhibits and educational materials, and information on collecting fossils. The next phase of development will target the development of resource modules on topics such as collection management and fossil preparation, appropriate for users ranging from the general public to professional paleontologists. Another initiative includes developing methods of personalizing the Portal to support exhibits at museums and other venues on geological history and paleontology. The Paleontology Portal, built by the UC Museum of Paleontology, is a joint project of the Society of Vertebrate Paleontology, the Paleontological Society, and the US Geological Survey, in collaboration with the Paleontological Research Institution, the Fort Worth Museum of Science and History, and the Denver Museum of Nature and Science, which serve as hubs for the project.

    The extrinsic gastrointestinal nerves are crucial in the sensing of nutrients and hormones and its translation in terms of control of food intake. Major macronutrients like glucose and protein are sensed by the extrinsic nerves located in the portal vein walls, which signal to the brain and account for the satiety phenomenon they promote. Glucose is sensed in the portal vein by neurons expressing the glucose receptor SGLT3, which activate the main regions of the brain involved in the control of food intake. Proteins indirectly act on food intake by inducing intestinal gluconeogenesis and its sensing by the portal glucose sensor. The mechanism involves a prior antagonism by peptides of the μ-opioid receptors present in the portal vein nervous system and a reflex arc with the brain inducing intestinal gluconeogenesis. In a comparable manner, short-chain fatty acids produced from soluble fibre act via intestinal gluconeogenesis to exert anti-obesity and anti-diabetic effects. In the case of propionate, the mechanism involves a prior activation of the free fatty acid receptor FFAR3 present in the portal nerves and a reflex arc initiating intestinal gluconeogenesis. © 2014 John Wiley & Sons Ltd.

    Increased resistance to portal flow and increased portal inflow due to mesenteric vasodilatation represent the main factors causing portal hypertension in cirrhosis. Endothelial cell dysfunction, defined as an imbalance between the synthesis, release, and effect of endothelial mediators of vascular tone, inflammation, thrombosis, and angiogenesis, plays a major role in the increase of resistance in portal circulation, in the decrease in the mesenteric one, in the development of collateral circulation. Reduced response to vasodilators in liver sinusoids and increased response in the mesenteric arterioles, and, viceversa, increased response to vasoconstrictors in the portal-sinusoidal circulation and decreased response in the mesenteric arterioles are also relevant to the pathophysiology of portal hypertension. Arachidonic acid (AA) metabolites through the three pathways, cyclooxygenase (COX), lipoxygenase, and cytochrome P450 monooxygenase and epoxygenase, are involved in endothelial dysfunction of portal hypertension. Increased thromboxane-A2 production by liver sinusoidal endothelial cells (LSECs) via increased COX-1 activity/expression, increased leukotriens, increased epoxyeicosatrienoic acids (EETs) (dilators of the peripheral arterial circulation, but vasoconstrictors of the portal-sinusoidal circulation), represent a major component in the increased portal resistance, in the decreased portal response to vasodilators and in the hyper-response to vasoconstrictors. Increased prostacyclin (PGI2) via COX-1 and COX-2 overexpression, and increased EETs/heme-oxygenase-1/K channels/gap junctions (endothelial derived hyperpolarizing factor system) play a major role in mesenteric vasodilatation, hyporeactivity to vasoconstrictors, and hyper-response to vasodilators. EETs, mediators of liver regeneration after hepatectomy and of angiogenesis, may play a role in the development of regenerative nodules and collateral circulation, through stimulation of vascular endothelial

    Background Despite conservative treatment, hemorrhage from an intrahepatic branch of the portal vein can cause hemodynamic instability requiring urgent intervention. Purpose To retrospectively report the outcomes of hemodynamically significant portal vein bleeding after endovascular management. Material and Methods During a period of 15 years, four patients (2 men, 2 women; median age, 70.5 years) underwent angiography and embolization for iatrogenic portal vein bleeding. Causes of hemorrhage, angiographic findings, endovascular treatment, and complications were reported. Results Portal vein bleeding occurred after percutaneous liver biopsy (n = 2), percutaneous radiofrequency ablation (n = 1), and percutaneous cholecystostomy (n = 1). The median time interval between angiography and percutaneous procedure was 5 h (range, 4-240 h). Common hepatic angiograms including indirect mesenteric portograms showed active portal vein bleeding into the peritoneal cavity with (n = 1) or without (n = 2) an arterioportal (AP) fistula, and portal vein pseudoaneurysm alone with an AP fistula (n = 1). Successful transcatheter arterial embolization (n = 2) or percutaneous transhepatic portal vein embolization (n = 2) was performed. Embolic materials were n-butyl cyanoacrylate alone (n = 2) or in combination with gelatin sponge particles and coils (n = 2). There were no major treatment-related complications or patient mortality within 30 days. Conclusion Patients with symptomatic or life-threatening portal vein bleeding following liver-penetrating procedures can successfully be managed with embolization.

    Irena Smetonienė

    2014-12-01

    Full Text Available The article is devoted to the analysis of realizations of euphemization in political discourse. Its focus is on news article headlines. The language data under study have been collected from the Internet news websites published in 2013–2014. The aim of the paper is twofold: to give an overview of recent cases of euphemization in news headlines, and to define functions, purpose and means of euphemization. The most frequently euphemized topics this year have been found to be war, military actions in different countries, politics and economics. The analysis of the news article headlines has showed that one of the main purposes of euphemization of social problems and political issues is to veil and cover up the real names of such phenomena as military actions, massacre, preparation for war, rising prices, unsuitable behavior of various officials, conflicts between leading politicians, bad economic conditions. The sub-topics of euphemization are concerned with the criticism of the behaviour of government leaders, leading politicians who are claimed to have violated ethics, who are arrogant, corrupt and dishonest. The semantics of euphemisms is best reflected describing them according to the means of euphemization, which are generalization, conceptual metaphorization, choice of international terms, periphrasis, pronominalization and litotes. Political euphemisms are part and parcel of the world of diplomacy, international and internal policy; politically correct language is crucial in today’s mass media communication. It seeks to avoid conflict and antagonism, reduce panic and anxiety, and to disguise unpleasant news.

    Portal vein embolization (PVE) may be performed before hemihepatectomy to increase the volume of future liver remnant (FLR) and to reduce the risk of postoperative liver insufficiency. We report the case of a 71-year-old patient with hilar cholangiocarcinoma undergoing PVE with access from the right portal vein using a mixture of n-butyl-2-cyanoacrylate and ethiodized oil. During the procedure, nontarget embolization of the left portal vein occurred. An aspiration maneuver of the polymerized plug failed; however, the embolus obstructing portal venous flow in the FLR was successfully relocated into the right portal vein while carefully bypassing the plug with a balloon catheter, inflating the balloon, and pulling the plug into the main right portal vein.

    Portal monitors are intended for detection of radioactive and special nuclear materials in vehicles, pedestrians, luggage, as well as for prevention of illegal traffic of radioactive sources. Monitors provide audio and visual alarms when radioactive and/or special nuclear materials are detected. They can be recommended to officers of customs, border guard and emergency services, civil defense, fire brigades, police and military departments or nuclear research or energetic facilities. The portal monitor developed by us consists in a portal frame, which sustains five intelligent probes having long plastic scintillator (0.5 liters each). The probes communicate, by serial transmission, with a Central Unit constructed on the basis of the 80552 microcontroller. This one manages the handshake, calculates the background, establishes the measuring time, starts and stops each measurement and makes all the other decisions. Sound signals and an infrared sensor monitor the passing through the portal and the measuring procedure. For each measurement the result is displayed on a LCD device contaminated/uncontaminated; for the contaminated case a loud and long sound signal is also issued. An RS 232 serial interface is provided in order to further developments or custom made devices. As a result, the portal monitor detects 1 μ Ci 137 Cs, spread all over a human body, in a 20 μR/h gamma background for a measuring time of 1.5 or 10 seconds giving a 99% confidence factor. (authors)

    (eg, strict regulations). Both similarities and differences were found between stakeholder groups and hospital types. For example, managers and information technology employees mainly considered guaranteeing privacy and security as a predominant barrier. Financial difficulties were particularly mentioned by medical professionals and managers. Patient portal implementation is a complex process and is not only a technical process but also affects the organization and its staff. Barriers and facilitators occurred at various levels and differed among hospital types (eg, lack of accessibility) and stakeholder groups (eg, sufficient resources) in terms of several factors. Our findings underscore the importance of involving multiple stakeholders in portal implementations. We identified a set of barriers and facilitators that are likely to be useful in making strategic and efficient implementation plans. ©Laura Kooij, Wim G Groen, Wim H van Harten.

  9. Endothelial dysfunction in the regulation of portal hypertension

    Science.gov (United States)

    Iwakiri, Yasuko

    2013-01-01

    Portal hypertension is caused by an increased intrahepatic resistance, a major consequence of cirrhosis. Endothelial dysfunction in liver sinusoidal endothelial cells (LSECs) decreases the production of vasodilators, such as nitric oxide (NO) and favors vasoconstriction. This contributes to an increased vascular resistance in the intrahepatic/sinusoidal microcirculation. Portal hypertension, once developed, causes endothelial cell (EC) dysfunction in the extrahepatic, i.e. splanchnic and systemic, circulation. Unlike LSEC dysfunction, EC dysfunction in the splanchnic and systemic circulation overproduces vasodilator molecules, leading to arterial vasodilatation. In addition, portal hypertension leads to the formation of portosystemic collateral vessels. Both arterial vasodilatation and portosystemic collateral vessel formation exacerbate portal hypertension by increasing the blood flow through the portal vein. Pathologic consequences, such as esophageal varices and ascites, result. While the sequence of pathological vascular events in cirrhosis and portal hypertension have been elucidated, the underlying cellular and molecular mechanisms causing EC dysfunctions are not yet fully understood. This review article summarizes the current cellular and molecular studies on EC dysfunctions found during the development of cirrhosis and portal hypertension with a focus on intra- and extrahepatic circulation. The article ends by discussing future directions of study for EC dysfunctions. PMID:21745318

    The duplication of the portal vein is an uncommon congenital anomaly. To date, only four cases have been reported in the medical literature. This anomaly can cause portal hypertension in pediatric patients. In addition, duplication of the portal vein has various patterns of connection with a splenic vein or mesenteric veins, and it can lie anterior or posterior to the duodenum. We report the MDCT findings of an adult patient with duplication of the portal vein that was found incidentally

    Forty-two MR imaging examinations and angiographic procedures in 38 patients with portal hypertension were compared for how well the images depicted portal perfusion and direction of flow, portal vein thrombosis, and the presence and type of shunt. Thirty-three MR imaging studies indicated grade I or II portal flow. In 29 cases portal flow was grade I or II by angiography; in the remaining cases the flow was grade IV. In a total of eight cases portal flow was grade IV by angiography, but none appeared to be grade IV on MR imaging. Both MR imaging and angiography detected portal vein thrombosis (41 of 42 cases). MR imaging and angiography agreed as to whether a shunt was present or absent, and patent or occluded (41 of 42 cases). Currently, MR imaging is an unsatisfactory modality by which to grade portal flow. MR imaging does depict portal vein thrombosis well, and can be used to determine patency of surgical shunts

    1998-01-01

    Full Text Available This study reports our experience of 8 cases of extrahepatic portal hypertension after 273 orthotopic liver transplantations in 244 adult patients over a 10- year period. The main clinical feature was ascites, and the life-threatening complication was variceal bleeding. Extrahepatic portal hypertension was caused by portal vein stenosis in 6 patients, and left-sided portal hypertension in 2 patients after inadventent ligation of portal venous tributaries or portasystemic shunts. All patients with portal vein stenosis had complete relief of portal hypertension after percutaneous transhepatic venoplasty (n=4 or surgical reconstruction (n=2, after a median follow-up of 33 (range: 6–62 months. Of the 2 patients with left-sided portal hypertension, one died after splenectomy and one rebled 6 months after left colectomy. This study suggests that extrahepatic portal hypertension is a series complication after liver transplantation that could be prevented by meticulous portal anastomosis and closure of portal tributaries or portasystemic shunts to improve the portal venous flow. However, any ligation has to be performed under ultrasound guidance to avoid inadventent venous ligations.

    1983-08-01

    The CT appearance of calcification in the portal venous system in a patient with chronic alcoholic cirrhosis is presented. Reported cases of radiologically detectable calcification in the portal system are rare, and most of them have been associated with longstanding portal hypertension. We presume that with CT this diagnosis will be made more frequently. In the presence of calcification in the portal venous system, portal vein thrombosis is highly probable. This information is of obvious importance to the surgeon contemplating a portal decompressive shunt procedure.

    Four patients with a long history of colitis, splenomegaly, hypersplenism and portal hypertension were examined with angiography, both with contrast medium and isotopes, liver-spleen scintigraphy and recording of portal pressure. At angiography hyperkinetic splenic and portal blood flow was demonstrated. The increased flow causes increased portal pressure, which probably gives rise to changes in the liver often considered as slight cirrhosis at microscopy. The scintigraphic findings differed from Laennec cirrhosis. The liver uptake was homogeneous and no activity in the skeleton was recorded. Splenectomy cures both the hypersplenism and portal hypertension. (Auth.)

    The liver is vulnerable to as host of disease processes, including portal hypertension. This is a severe hepatic condition in which the liver is subject to numerous imbalances: increased hepatic blood flow, increased portal vein pressure due to extrahepatic portal vein obstruction, and/or increases in hepatic blood flow resistance. Although many diseases states may be responsible for the development of portal hypertension, it is most commonly associated with moderately severe or advanced cirrhosis. Advanced, untreated portal hypertension may cause additional complications such as hepatosplenomegaly, gastrointestinal bleeding, and ascites

    Full Text Available Rhythm is central to news reading in radio and television programs. This paper proposes a three level structure for rhythm in news discourse. It gives a comprehensive definition of rhythm and types of rhythm. Firstly, the Base Rhythm Structure consists of semantic and pragmatic rhythmic accents, coincident with very specific words. Secondly, these accents are grouped together according to type, frequency and order, thereby configuring three types of “rhythmic units” (the Internal Rhythm Structure: starting, main and end units. A last structure level presents four discursive factors that are very important in integrating the overall time structure of news announcing (the Melodic Rhythm Structure. This integral structure for news announcing rhythm should be further tested in acoustic-experimental studies under the criterion of information transmission efficacy.

    The NASA Sea Level Change Portal (https://sealevel.nasa.gov) is designed as a "one-stop" source for current sea level change information, including interactive tools for accessing and viewing regional data, a virtual dashboard of sea level indicators, and ongoing updates through a suite of editorial products that include content articles, graphics, videos, and animations. With increasing global temperatures warming the ocean and melting ice sheets and glaciers, there is an immediate need both for accelerating sea level change research and for making this research accessible to scientists in disparate discipline, to the general public, to policy makers and business. The immersive and innovative NASA portal debuted at the 2015 AGU attracts thousands of daily visitors and over 30K followers on Facebook®. Behind its intuitive interface is an extensible architecture that integrates site contents, data for various sources, visualization, horizontal-scale geospatial data analytic technology (called NEXUS), and an interactive 3D simulation platform (called the Virtual Earth System Laboratory). We will present an overview of our NASA portal and some of our architectural decisions along with discussion on our open-source, cloud-based data analytic technology that enables on-the-fly analysis of heterogeneous data.

    Full Text Available Recommending news stories to users, based on their preferences, has long been a favourite domain for recommender systems research. Traditional systems strive to satisfy their user by tracing users' reading history and choosing the proper candidate news articles to recommend. However, most of news websites hardly require any user to register before reading news. Besides, the latent relations between news and microblog, the popularity of particular news, and the news organization are not addressed or solved efficiently in previous approaches. In order to solve these issues, we propose an effective personalized news recommendation method based on microblog user profile building and sub class popularity prediction, in which we propose a news organization method using hybrid classification and clustering, implement a sub class popularity prediction method, and construct user profile according to our actual situation. We had designed several experiments compared to the state-of-the-art approaches on a real world dataset, and the experimental results demonstrate that our system significantly improves the accuracy and diversity in mass text data.

    Scintiphotosplenoportograpy (SSP) was performed in five normals and 25 patients with portal hypertension using Tc-99m tin colloid. 12 patients were cirrhotic and 13 had idiopathic portal hypertension (IPH). Analogue and fast frame dynamic studies were performed and subsequently processed. Intra hepatic shunt index in cirrhotics was significantly different from the IPH group. Extra hepatic shunt index, however, was not significantly different in the two groups but was related more to the severity of the disease process. Spleno hepatic and spleno cardiac transit times were significantly lower cirrhotics as compared to the IPH group. We conclude that SSP is a technically simple, rapid and a much less invasive method of visualizing the portal circulatory system and assessing the portal haemo dynamics. it also provides clinically important measure of shunted blood nd allows for the quantification of circulatory time from spleen to liver and heart.

    , the website offers easy navigation, and user friendly functionalities. New features also include a section on news and airborne research stories to keep users up-to-date on EUFAR's activities, a career section, photo galleries, and much more. By elaborating new solutions for the web portal, EUFAR continues to serve as an interactive and dynamic platform bringing together experts, early-stage researchers, operators, data users, industry and other stakeholders in the airborne research community. A main focus of the current project is the establishment of a sustainable legal structure for EUFAR. This is critical to ensuring the continuity of EUFAR and securing, at the least, partial financial independence from the European Commission who has been funding the project since its start. After carefully examining different legal forms relevant for EUFAR, the arguments are strongly in favour of establishing an International non-profit Association under the Belgian law (AISBL). Together with the implementation of an Open Access scheme by means of resource-sharing to support the mobility of personnel across countries envisaged in 2016, such a sustainable structure would contribute substantially toward broadening the user base of existing airborne research facilities in Europe and mobilising additional resources for this end. In essence, this would cement EUFAR's position as the key portal for airborne research in Europe.

    The aim of this study was to evaluate the Internet use of a group of lumbar disc surgery candidates in order to determine the rate of Internet search by the patients on their disorders and more importantly the reliability of the accessed websites. Fifty patients who were scheduled for lumbar disc surgery were divided into 2 groups, namely patients who accepted the surgery at the first offer and those who wanted to think over. Educational level information was obtained and patients were asked whether they had searched their disorder and offered surgery on the Internet. Then, a questionnaire was administered and the reliability of the websites was evaluated. Correction: The first 30 websites on the first 3 pages of Google ® search engine, the most commonly used search engine in Turkey, were evaluated with the DISCERN ® instrument. Of 50 patients, 33 (66%) had conducted a search for the surgery on the Internet. All university graduates, 88.2% of high school graduates, and 18.7% of primary-secondary school graduates had conducted an Internet search. The quality and reliability of the information was high (4.5 points) for 2 (7.1%) websites, moderate (2.3 points) for 6 websites (21.4%) and poor (1 point) for 20 websites (71.4%) as scored with the DISCERN ® instrument. The mean DISCERN ® score of was 1.1 for websites of health-related institutions or healthcare news, 2.75 for personal websites of physicians and 2.5 for personal websites of non-physicians. The mean DISCERN ® score of all websites was 1.5. Most of the patients undergoing lumbar disc surgery at our clinic had searched information about the surgical procedure on the Internet. We found that 92.9% of the websites evaluated with the DISCERN ® instrument had inadequate information, suggesting low-level reliability. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study aimed to evaluate the common features and variations of portal vein anatomy in right-sided round ligament (RSRL), which can help propose a method to detect and diagnose this anomaly. In this retrospective study of 14 patients with RSRL, the branching order of the portal tree was analyzed, with special focus on the relationship between the dorsal branch of the right anterior segmental portal vein (P A-D ) and the lateral segmental portal vein (P LL ), to determine the common features. The configuration of the portal vein from the main portal trunk to the right umbilical portion (RUP), the inclination of the RUP, and the number and thickness of the ramifications branching from the right anterior segmental portal vein (P A ) were evaluated for variations. In all subjects, the diverging point of the P A-D was constantly distal to that of the P LL . The portal vein configuration was I- and Z-shaped in nine and five subjects, respectively. The RUP was tilted to the right in all subjects. In Z-shaped subjects, the portal trunk between the branching point of the right posterior segmental portal vein and that of the P LL was tilted to the left in one subject and was almost parallel to the vertical plane in four subjects. Multiple ramifications were radially distributed from the P A in eight subjects, whereas one predominant P A-D branched from the P A in six subjects. Based on the diverging points of the P A-D and P LL , we proposed a three-step method for the detection and diagnosis of RSRL.

    1992-01-01

    The portal monitoring of pedestrians, packages, equipment, and vehicles entering or leaving areas of high physical security has been common for many years. Many nuclear facilities rely on portal monitoring to prevent the theft or diversion of plutonium and highly enriched uranium. At commercial airports, portals are used to prevent firearms and explosives from being smuggled onto airplanes. An August 1989 Federal Aviation Administration (FAA) regulation requires US airlines to screen luggage on international flights for chemical explosives. This paper reports that portal monitoring is now being introduced into arms-control agreements. Because some of the portal-monitoring equipment that would be useful in verifying arms-control agreements is already widely used as part of the physical security systems at nuclear facilities and commercial airports, the authors review these uses of portal monitoring, as well as its role in verifying the INF treaty. Then the authors survey the major types of portal-monitoring equipment that would be most useful in detecting nuclear warheads or fissile material

    In this age of digital technology, Internet, and social media we are increasingly subjected to an information and disinformation overload. This includes not only political and economic information but also medical news, which is often presented as a "new discovery", "miracle cure" or some other press hyperbole. In this viewpoint article we present patient and scientific perspectives some recent episodes of medical hype related to Parkinson's disease research, including proposed therapies such as nilotinib, marijuana, stem cells and other controversial therapies that have attracted the mainstream and social media. We conclude by emphasizing the importance of vigilance on the part of patients and physicians when interpreting these often exaggerated and/or unfounded health claims. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    To design and evaluate the usage of an adolescent patient portal specifically adapted for adolescent health care needs that also satisfied institutional meaningful use guidelines regarding electronic health records. Key stakeholders at one academic health care center adopted an online portal and opted to designate a patient portal specifically for adolescents to maximize confidentiality in compliance with state privacy laws. This study analyzed aggregate electronic health record data of adolescents' (ages 12-17.9 years) uptake, usage, and functionality of this portal and compared it to parent portal usage for younger children (ages 0-11 years). Differences in means were calculated using paired t tests. The portal was used similarly between parents of young children and adolescents, with almost 1,000 enrollees in each group from September 1, 2012 to March 31, 2015. There were no gender differences in enrollment. Adolescents were less likely than parents of younger children to review appointments (73% vs. 85%), laboratory tests (67% vs. 79%), problem lists (40% vs. 78%), or allergies (45% vs. 77%, all p values adolescents sent 1,397 confidential messages. Institutional decisions for implementing meaningful use requirements can align with goals of adolescent health. Patient portals can enhance adolescent health care quality and adolescents readily use a confidential portal. Implementation of meaningful use requirements should be checked against adolescent health care needs to maximize confidentiality and promote health communication.

    Patient portals, web-based personal health records linked to electronic health records (EHRs), provide patients access to their healthcare information and facilitate communication with providers. Growing evidence supports portal use in ambulatory settings; however, only recently have portals been used with hospitalized patients. Our objective was to review the literature evaluating the design, use, and impact of inpatient portals, which are patient portals designed to give hospitalized patients and caregivers inpatient EHR clinical information for the purpose of engaging them in hospital care. Literature was reviewed from 2006 to 2017 in PubMed, Web of Science, CINALPlus, Cochrane, and Scopus to identify English language studies evaluating patient portals, engagement, and inpatient care. Data were analyzed considering the following 3 themes: inpatient portal design, use and usability, and impact. Of 731 studies, 17 were included, 9 of which were published after 2015. Most studies were qualitative with small samples focusing on inpatient portal design; 1 nonrandomized trial was identified. Studies described hospitalized patients' and caregivers' information needs and design recommendations. Most patient and caregiver participants in included studies were interested in using an inpatient portal, used it when offered, and found it easy to use and/or useful. Evidence supporting the role of inpatient portals in improving patient and caregiver engagement, knowledge, communication, and care quality and safety is limited. Included studies indicated providers had concerns about using inpatient portals; however, the extent to which these concerns have been realized remains unclear. Inpatient portal research is emerging. Further investigation is needed to optimally design inpatient portals to maximize potential benefits for hospitalized patients and caregivers while minimizing unintended consequences for healthcare teams. © 2017 Society of Hospital Medicine.
