The University of Victoria Interdisciplinary Electronic Health Record Educational Portal.  

PubMed

Use of Electronic Health Record (EHR) systems is increasing globally. However, adoption rates of Health Information Systems (HISs) continue to remain poor. To improve adoption rates, there is need to provide greater HIS experience to health professionals and informaticians in health and biomedicine during their undergraduate and graduate education. A recent review of the health professional educational curricula (i.e., medicine, nursing, allied health and health/biomedical informatics) revealed that they provide only limited exposure to EHRs. In response to this educational need, the authors have developed the University of Victoria Interdisciplinary Electronic Health Record Educational Portal (UVicIED-EHR Portal). This unique, web-based portal allows students of the health professions and practicing professionals to access and interact with a set of representative EHR HIS solutions using the web. The portal, which links to several EMRs, EPRs and PHRs, has been used by several health professional educational programs in medicine, nursing and health informatics. It provides practicing health and health/biomedical informatics professionals, for example, managers and directors, with opportunities to access and review EHR systems. The portal has been used successfully in the classroom, laboratory and with distance education to give hands-on experience with a variety of HISs and their components. PMID:19380914

Supporting the education evidence portal via text mining  

PubMed Central

The UK Education Evidence Portal (eep) provides a single, searchable, point of access to the contents of the websites of 33 organizations relating to education, with the aim of revolutionizing work practices for the education community. Use of the portal alleviates the need to spend time searching multiple resources to find relevant information. However, the combined content of the websites of interest is still very large (over 500?000 documents and growing). This means that searches using the portal can produce very large numbers of hits. As users often have limited time, they would benefit from enhanced methods of performing searches and viewing results, allowing them to drill down to information of interest more efficiently, without having to sift through potentially long lists of irrelevant documents. The Joint Information Systems Committee (JISC)-funded ASSIST project has produced a prototype web interface to demonstrate the applicability of integrating a number of text-mining tools and methods into the eep, to facilitate an enhanced searching, browsing and document-viewing experience. New features include automatic classification of documents according to a taxonomy, automatic clustering of search results according to similar document content, and automatic identification and highlighting of key terms within documents.

Quantitative Analysis of the Usage of the COSMOS Science Education Portal  

NASA Astrophysics Data System (ADS)

A quantitative method of mapping the web usage of an innovative educational portal is applied to analyze the behaviour of users of the COSMOS Science Education Portal. The COSMOS Portal contains user-generated resources (that are uploaded by its users). It has been designed to support a science teacher's search, retrieval and access to both, scientific and educational resources. It also aims to introduce in and familiarize teachers with an innovative methodology for designing, expressing and representing educational practices in a commonly understandable way through the use of user-friendly authoring tools that are available through the portal. As a new science education portal that includes user-generated content, the COSMOS Portal encounters the well-known "new product/service challenge": to convince the users to use its tools, which facilitate quite fast lesson planning and lesson preparation activities. To respond to this challenge, the COSMOS Portal operators implemented a validation process by analyzing the usage data of the portal in a 10 month time-period. The data analyzed comprised: (a) the temporal evolution of the number of contributors and the amount of content uploaded to the COSMOS Portal; (b) the number of portal visitors (categorized as all-visitors, new-visitors, and returning-visitors) and (c) visitor loyalty parameters (such as page-views; pages/visit; average time on site; depth of visit; length of visit). The data is augmented with data associated with the usage context (e.g. the time of day when most of the activities in the portal take place). The quantitative results indicate that the exponential growth of the contributors to the COSMOS Portal is followed by an exponential growth of the uploaded content. Furthermore, the web usage statistics demonstrate significant changes in users' behaviour during the period under study, with returning visitors using the COSMOS Portal more frequently, mainly for lesson planning and preparation (in the afternoon hours). The findings demonstrate that the new COSMOS users follow the "law of surfing" behaviour, a common pattern of surfing behaviour in portals. However, users return to the COSMOS Portal: returning users comprise more than 50% of all COSMOS visits, stay longer on site and visit more pages. Returning visitors are benchmarked against the "law of surfing" and outperform it substantially. These quantitative results benchmark the web usage of a portal and provide its operators with maps of value-added patterns of the portal's offering to its users in the science education community.

Advanced proficiency EHR training: effect on physicians' EHR efficiency, EHR satisfaction and job satisfaction.  

PubMed

The best way to train clinicians to optimize their use of the Electronic Health Record (EHR) remains unclear. Approaches range from web-based training, class-room training, EHR functionality training, case-based training, role-based training, process-based training, mock-clinic training and "on the job" training. Similarly, the optimal timing of training remains unclear--whether to engage in extensive pre go-live training vs. minimal pre go-live training followed by more extensive post go-live training. In addition, the effectiveness of non-clinician trainers, clinician trainers, and peer-trainers, remains unclearly defined. This paper describes a program in which relatively experienced clinician users of an EHR underwent an intensive 3-day Peer-Led EHR advanced proficiency training, and the results of that training based on participant surveys. It highlights the effectiveness of Peer-Led Proficiency Training of existing experienced clinician EHR users in improving self-reported efficiency and satisfaction with an EHR and improvements in perceived work-life balance and job satisfaction.

Challenges to EHR Implementation in Electronic- Versus Paper-based Office Practices  

PubMed Central

Summary Background Challenges in implementing electronic health records (EHRs) have received some attention, but less is known about the process of transitioning from legacy EHRs to newer systems. Objective To determine how ambulatory leaders differentiate implementation approaches between practices that are currently paper-based and those with a legacy EHR system (EHR-based). Design Qualitative study. Participants Eleven practice managers and 12 medical directors all part of an academic ambulatory care network of a large teaching hospital in New York City in January to May of 2006. Approach Qualitative approach comparing and contrasting perceived benefits and challenges in implementing an ambulatory EHR between practice leaders from paper- and EHR-based practices. Content analysis was performed using grounded theory and ATLAS.ti 5.0. Results We found that paper-based leaders prioritized the following: sufficient workstations and printers, a physician information technology (IT) champion at the practice, workflow education to ensure a successful transition to a paperless medical practice, and a high existing comfort level of practitioners and support staff with IT. In contrast, EHR-based leaders prioritized: improved technical training and ongoing technical support, sufficient protection of patient privacy, and open recognition of physician resistance, especially for those who were loyal to a legacy EHR. Unlike paper-based practices, EHR-based leadership believed that comfort level with IT and adjustments to workflow changes would not be difficult challenges to overcome. Conclusions Leadership at paper- and EHR-based practices in 1 academic network has different priorities for implementing a new EHR. Ambulatory practices upgrading their legacy EHR have unique challenges. PMID:18369679

MedEdPORTAL: a report on oral health resources for health professions educators.  

PubMed

MedEdPORTAL is a unique web-based peer-reviewed publication venue for clinical health educators sponsored by the Association of American Medical Colleges (AAMC). The open exchange of educational resources promotes professional collaboration across health professions. In 2008, the American Dental Education Association (ADEA) collaborated with AAMC to allow dental educators to use the platform to publish dental curriculum resources. Oral health is integral to general health; hence, collaboration among health care professionals brings enormous value to patient-centered care. The aim of this study was to conduct a current survey of metrics and submission statistics of MedEdPORTAL resources. The data were collected using the MedEdPORTAL search engine and ADEA and AAMC staff. The data collected were categorized and reported in tables and charts. Results showed that at the time of this study there were over 2,000 medical and dental resources available to anyone worldwide. Oral health resources constituted approximately 30 percent of the total resources, which included cross-indexing with information relevant to both medical and dental audiences. There were several types of dental resources available; the most common were the ones focusing on critical thinking. The usage of MedEdPORTAL has been growing, with participation from over 190 countries and 10,000 educational institutions around the world. The findings of this report suggest that MedEdPORTAL is succeeding in its aim to foster global collaborative education, professional education, and educational scholarship. As such, MedEdPORTAL is providing a new forum for collaboration and opens venues for promising future work in professional education. PMID:24002849

PubMed Central

Background: The main objective of creating a portal is to make information service available for users who need them for performance of duties and responsibilities regardless of the sources. This article is attempted to consider the parameters that can evaluate these sites since these criteria can be effective in designing and implementing such portals. On the other hand, portal sites in health systems of every country make it possible for leaders, policy makers, and directors to system education as a tool for new learning technologies. One of the main decisions each manager has to make is precise selection of appropriate portal sites. Materials and Methods: This is a descriptive and qualitative study. The research sample was 53 computer professional working in the area of computer programming and design. In the first part of the study a questionnaire was send to the participants and in the second part of the study based on their response to the questionnaire the participant was interviewed and the main themes of the studies were formulated. The validity and the reliability of the questionnaire were confirmed. Results: The study results were summarized in 10 themes and 50 sub-categories. The main themes included were portal requirements, security, management, and efficiency, user friendliness, built-in applications, portal flexibility, interoperability, and support systems. Conclusion: Portal sites in any education systems make it possible for health system leaders and policy makers to manage their organization information system efficiently and effectively. One of the major decisions each manager has to make is precise selection of an appropriate portal sites design and development. The themes and sub-categories of this study could help health system managers and policy makers and information technology professionals to make appropriate decisions regarding portal design and development.

EHR Big Data Deep Phenotyping  

PubMed Central

Summary Objectives Given the quickening speed of discovery of variant disease drivers from combined patient genotype and phenotype data, the objective is to provide methodology using big data technology to support the definition of deep phenotypes in medical records. Methods As the vast stores of genomic information increase with next generation sequencing, the importance of deep phenotyping increases. The growth of genomic data and adoption of Electronic Health Records (EHR) in medicine provides a unique opportunity to integrate phenotype and genotype data into medical records. The method by which collections of clinical findings and other health related data are leveraged to form meaningful phenotypes is an active area of research. Longitudinal data stored in EHRs provide a wealth of information that can be used to construct phenotypes of patients. We focus on a practical problem around data integration for deep phenotype identification within EHR data. The use of big data approaches are described that enable scalable markup of EHR events that can be used for semantic and temporal similarity analysis to support the identification of phenotype and genotype relationships. Conclusions Stead and colleagues’ 2005 concept of using light standards to increase the productivity of software systems by riding on the wave of hardware/processing power is described as a harbinger for designing future healthcare systems. The big data solution, using flexible markup, provides a route to improved utilization of processing power for organizing patient records in genotype and phenotype research. PMID:25123744

The SERC K12 Educators Portal to Teaching Activities and Pedagogic Approaches  

NASA Astrophysics Data System (ADS)

The Science Education Resource Center (SERC) has created a portal to information for K12 educators to provide high-quality grade level appropriate materials from a wide variety of projects and topics. These materials were compiled across the SERC site, showcasing materials that were created for, or easily adaptable to, K12 classrooms. This resource will help support implementation of Next Generation Science Standards by assisting educators in finding innovative resources to address areas of instruction that are conceptually different than previous national and state science standards. Specifically, the K12 portal assists educators in learning about approaches that address the cross-cutting nature of science concepts, increasing students quantitative reasoning and numeracy skills, incorporating technology such as GIS in the classroom, and by assisting educators of all levels of K12 instruction in using relevant and meaningful ways to teach science concepts. The K12 portal supports educators by providing access to hundreds of teaching activities covering a wide array of science topics and grade levels many of which have been rigorously reviewed for pedagogic quality and scientific accuracy. The portal also provides access to web pages that enhance teaching practices that help increase student's system thinking skills, make lectures interactive, assist instructors in conducting safe and effective indoor and outdoor labs, providing support for teaching energy and climate literacy principles, assisting educators in addressing controversial content, provide guidance in engaging students affective domain, and provides a collection of tools for making teaching relevant in 21st century classrooms including using GIS, Google Earth, videos, visualizations and simulations to model and describe scientific concepts. The portal also provides access to material for specific content and audiences by (1) Supporting AGIs 'Map your World' week to specifically highlight teaching activities and approaches that use maps as the basis of instruction for a wide range of topics commonly taught in K12 science courses such as natural hazards, urban development, plate tectonics, climate change, ocean science, and water resources; and (2) Providing easy access to a vast collection of materials specifically for teachers of AP and IB classes including collections of teaching activities for all science disciplines as well as pedagogic approaches that are appropriate for the lab-intensive nature of these classes. The contents of the K12 portal are drawn from a number of projects and collaborations, including CLEAN, Earth Exploration Toolbook, Minnesota Science Teachers Education Project, Pedagogy in Action, EarthLabs, NAGT and On the Cutting Edge. Teachers can add their own materials to the site by sharing lessons plans, activities, and labs. K12 educators of all levels will find a wide variety of resources to spark the curiosity and interest of students. Explore the SERC K12 Educators Portal at: http://serc.carleton.edu/k12/index.html

An educational portal to facilitate statistical literacy for the Malaysian community  

NASA Astrophysics Data System (ADS)

In the last decades, a considerable number of studies investigated the teaching and learning of statistics. The implications of these studies have changed the content and structure of statistics. Hence, the applications of statistics to understand the world around us should be followed by the learning of statistical concepts so that the students are aware that statistics is an important tool to solve practical life problems. There must be some platform such as materials or articles that discuss explicitly the applications of statistics in various area that reach of students. An educational web portal by the name of Dunia Matematik has been delegated to meet this need. Apart from the sections which provide numerous articles that portray statistics in real life, the portal also provides articles on history in mathematics, popular mathematicians, online quizzes, technology in mathematics education and arts in mathematics. Based on ARCS model on motivation, the four components of the model, namely attention, relevance, confidence and satisfaction are integrated in the design of the articles and activities. A rich collection of such resources which present authentic data could supplement text book materials which heavily focus onto statistical concepts and procedures. Besides motivating learning, it is expected that the web portal has the potential to develop statistical literacy, an ability to comprehend and infer the data. The final part of the paper will describe some resources that have been developed.

The portal of geriatrics online education: a 21st-century resource for teaching geriatrics.  

PubMed

The way students are taught and evaluated is changing, with greater emphasis on flexible, individualized, learner-centered education, including the use of technology. The goal of assessment is also shifting from what students know to how they perform in practice settings. Developing educational materials for teaching in these ways is time-consuming and can be expensive. The Portal of Geriatrics Online Education (POGOe) was developed to aid educators in meeting these needs and become quicker, better-prepared teachers of geriatrics. POGOe contains more than 950 geriatrics educational materials that faculty at 45% of allopathic and 7% of osteopathic U.S. medical schools and the Centers for Geriatric Nursing Excellence have created. These materials include various instructional and assessment methodologies, including virtual and standardized patients, games, tutorials, case-based teaching, self-directed learning, and traditional lectures. Materials with common goals and resource types are available as selected educational series. Learner assessments comprise approximately 10% of the educational materials. POGOe also includes libraries of videos, images, and questions extracted from its educational materials to encourage educators to repurpose content components to create new resources and to align their teaching better with their learners' needs. Web-Geriatric Education Modules, a peer-reviewed online modular curriculum for medical students, is a prime example of this repurposing. The existence of a robust compendium of instructional and assessment materials allows educators to concentrate more on improving learner performance in practice and not simply on knowledge acquisition. It also makes it easier for nongeriatricians to teach the care of older adults in their respective disciplines. PMID:25644187

A secure EHR system based on hybrid clouds.  

PubMed

Consequently, application services rendering remote medical services and electronic health record (EHR) have become a hot topic and stimulating increased interest in studying this subject in recent years. Information and communication technologies have been applied to the medical services and healthcare area for a number of years to resolve problems in medical management. Sharing EHR information can provide professional medical programs with consultancy, evaluation, and tracing services can certainly improve accessibility to the public receiving medical services or medical information at remote sites. With the widespread use of EHR, building a secure EHR sharing environment has attracted a lot of attention in both healthcare industry and academic community. Cloud computing paradigm is one of the popular healthIT infrastructures for facilitating EHR sharing and EHR integration. In this paper, we propose an EHR sharing and integration system in healthcare clouds and analyze the arising security and privacy issues in access and management of EHRs. PMID:22351166

Dynamic CDM strategies in an EHR environment.  

PubMed

A dynamic charge description master (CDM) integrates information from clinical ancillary systems into the charge-capture process, so an organization can reduce its reliance on the patient accounting system as the sole source of billing information. By leveraging the information from electronic ancillary systems, providers can eliminate the need for paper charge-capture forms and see increased accuracy and efficiency in the maintenance of billing information. Before embarking on a dynamic CDM strategy, organizations should first determine their goals for implementing an EHR system, include revenue cycle leaders on the EHR implementation team, and carefully weigh the pros and cons of CDM design decisions.

Evaluation of a web-based portal to improve resident education by neonatology fellows  

PubMed Central

Background Integration of web-based educational tools into medical training has been shown to increase accessibility of resources and optimize teaching. We developed a web-based educational portal (WBEP) to support teaching of pediatric residents about newborn medicine by neonatology fellows. Objectives 1) To compare residents’ attitudes about their fellow-led education in the NICU pre- and post-WBEP; including assessment of factors that impact their education and usefulness of teaching tools. 2) To compare fellow utilization of various teaching modalities pre- and post-WBEP. Design/methods We queried residents about their attitudes regarding fellow-led education efforts and various teaching modalities in the NICU and logistics potentially impacting effectiveness. Based on these data, we introduced the WBEP – a repository of teaching tools (e.g., mock code cases, board review questions, journal articles, case-based discussion scenarios) for use by fellows to supplement didactic sessions in a faculty-based curriculum. We surveyed residents about the effectiveness of fellow teaching pre- and post-WBEP implementation and the type of fellow-led teaching modalities that were used. Results After analysis of survey responses, we identified that residents cited fellow level of interest as the most important factor impacting their education. Post-implementation, residents described greater utilization of various teaching modalities by fellows, including an increase in use of mock codes (14% to 76%, p<0.0001) and journal articles (33% to 59%, p=0.02). Conclusions A web-based resource that supplements traditional curricula led to greater utilization of various teaching modalities by fellows and may encourage fellow involvement in resident teaching.

Archetype Model-Driven Development Framework for EHR Web System  

PubMed Central

Objectives This article describes the Web application framework for Electronic Health Records (EHRs) we have developed to reduce construction costs for EHR sytems. Methods The openEHR project has developed clinical model driven architecture for future-proof interoperable EHR systems. This project provides the specifications to standardize clinical domain model implementations, upon which the ISO/CEN 13606 standards are based. The reference implementation has been formally described in Eiffel. Moreover C# and Java implementations have been developed as reference. While scripting languages had been more popular because of their higher efficiency and faster development in recent years, they had not been involved in the openEHR implementations. From 2007, we have used the Ruby language and Ruby on Rails (RoR) as an agile development platform to implement EHR systems, which is in conformity with the openEHR specifications. Results We implemented almost all of the specifications, the Archetype Definition Language parser, and RoR scaffold generator from archetype. Although some problems have emerged, most of them have been resolved. Conclusions We have provided an agile EHR Web framework, which can build up Web systems from archetype models using RoR. The feasibility of the archetype model to provide semantic interoperability of EHRs has been demonstrated and we have verified that that it is suitable for the construction of EHR systems.

How to dwell in an EHR. The question concerning architecture EHR.  

PubMed

The article deals with architecture and EHRs on a conceptual and philosophical level. Architecture is seen as the essential human expression of being, exemplified through the thoughts and writings of the German architect Gottfried Semper, the American architect Philip Johnson and the German philosopher Martin Heidegger. It is the assumption of the article that the current versions of EHR architectures are the result of a technical and systemic perspective on architecture, as opposed to the thoughts of Semper, Johnson and Heidegger. The article has a value-based and phronetic approach to the topic field, and claims that construction of EHRs should be a matter of concern, and not, as it is for now, a matter of fact.

Protection of electronic health records (EHRs) in cloud.  

PubMed

EHR technology has come into widespread use and has attracted attention in healthcare institutions as well as in research. Cloud services are used to build efficient EHR systems and obtain the greatest benefits of EHR implementation. Many issues relating to building an ideal EHR system in the cloud, especially the tradeoff between flexibility and security, have recently surfaced. The privacy of patient records in cloud platforms is still a point of contention. In this research, we are going to improve the management of access control by restricting participants' access through the use of distinct encrypted parameters for each participant in the cloud-based database. Also, we implement and improve an existing secure index search algorithm to enhance the efficiency of information control and flow through a cloud-based EHR system. At the final stage, we contribute to the design of reliable, flexible and secure access control, enabling quick access to EHR information. PMID:24110656

Transitioning between ambulatory EHRs: a study of practitioners' perspectives  

PubMed Central

Objective To evaluate practitioners' expectations of, and satisfaction with, older and newer electronic health records (EHRs) after a transition. Material and methods Pre- and post-transition survey administered at six academic-affiliated ambulatory care practices from 2006 to 2008. Four practices transitioned to one commercial EHR and two practices to another. We compared respondents' expectations of, and satisfaction with, the newer EHR. Results 523 subjects were eligible: 217 were available before transition and 306 after transition. 162 pre-transition and 197 post-transition responses were received, yielding 75% and 64% response rates, respectively. Practitioners were more satisfied with the newer EHRs (64%) compared with the older (56%) (p=0.15) and a small majority (58%) were satisfied with the transition. Practitioners' satisfaction with the older EHRs for completing clinical tasks was high. The newer EHRs exceeded practitioner expectations regarding remote access (61% vs 74%; p=0.03). However, the newer EHRs did not meet practitioners' expectations regarding their ability to perform clinical tasks, or more globally, improve medication safety (81% vs 61%; p<0.001), efficiency (70% vs 44%; p<0.001), and quality of care (77% vs 67%; p=0.04). Discussion Most practitioners had favorable opinions about EHRs and reported overall improved satisfaction with the newer EHRs. However, practitioners' high expectations of the newer EHRs were often unmet regarding facilitation of specific clinical tasks or for improving quality, safety, and efficiency. Conclusion To ensure practitioners' expectations, for instance regarding improvements in medication safety, are met, vendors should develop and implement refinements in their software as practices upgrade to newer, certified EHRs.

Organization's quality maturity as a vehicle for EHR success.  

PubMed

In health care industry, EHR has been advocated to improve care quality. The journey toward the development and adaptation of EHR should be holistic and integrate all the EHR's building blocks-health record management, business process improvement (BPI), collaboration and innovation, change management, user governance, etc.-that are intertwined together as like the links of a chain to improve quality of health care services. These cornerstones that shares common features with quality principles will pave the way for implementing EHR. To go along with quality features and take advantage of quality principles namely "quality maturity" builds a solid foundation for adaptation of EHR. Therefore, the recent theories of EHR success go far beyond technical rationales and focus on organizational and managerial factors in quality improvement. The milestone of quality concept in information system success is revealed in Delone and Mclean's model which launches system quality, information quality, service quality, as distinct elements of the IS success. EHR is a means to an end -to improve quality within enterprises- based on quality approaches. In this regards, more research should be conducted to investigate the relationship between of organization's quality maturity and EHR development success. PMID:20878212

Supporting Geoscientists in Partnerships for K-12 Education at NSF  

NASA Astrophysics Data System (ADS)

NSF Directorate for Geosciences (GEO) education activities have evolved over the last decade based on advice from a broad segment of the geosciences community. These activities gained momentum when a Geosciences Education Working Group (GEWG, 1996) recognized the shift from traditional priorities that emphasized only research, to those that support education in geosciences as well. The GEWG report embraced this increased emphasis on education as a component of NSF's role in assuring the long-term health of the geosciences and endorsed the principle that research and education should be well integrated. While many geosciences education activities are funded by the Education and Human Resources Directorate (EHR) of NSF, the GEWG report highlighted the need to have more active participation by research geoscientists in K-12 education activities, and the need to train them to be able to do so. While some roles in education are clearly best left to educational professionals (e.g. large-scale systemic reform projects, pedagogical development at the K-12 level, and many teacher enhancement projects), activities such as undergraduate research, technology advancement, curriculum content development and informal science are ones in which GEO should actively seek to collaborate with programs in EHR. The GEO education program has expanded over the last decade. Our first education activity, Awards to Facilitate Geoscience Education (AFGE), was very successful in attracting some of the leading researchers in geosciences. This program evolved to become the Geoscience Education Program. An important program funded by GEO that developed from community activity is the Digital Library for Earth System Education (DLESE). This program grew out of a joint EHR/GEO award and a series of community workshops. The program will establish an Internet portal for geoscience curricular materials and other teacher resources that will enable further collaboration between the research and education communities in geoscience.

WormClassroom.org: An Inquiry-rich Educational Web Portal for Research Resources of Caenorhabditis elegans  

PubMed Central

The utilization of biology research resources, coupled with a “learning by inquiry” approach, has great potential to aid students in gaining an understanding of fundamental biological principles. To help realize this potential, we have developed a Web portal for undergraduate biology education, WormClassroom.org, based on current research resources of a model research organism, Caenorhabditis elegans. This portal is intended to serve as a resource gateway for students to learn biological concepts using C. elegans research material. The driving forces behind the WormClassroom website were the strengths of C. elegans as a teaching organism, getting researchers and educators to work together to develop instructional materials, and the 3 P's (problem posing, problem solving, and peer persuasion) approach for inquiry learning. Iterative assessment is an important aspect of the WormClassroom site development because it not only ensures that content is up-to-date and accurate, but also verifies that it does, in fact, aid student learning. A primary assessment was performed to refine the WormClassroom website utilizing undergraduate biology students and nonstudent experts such as C. elegans researchers; results and comments were used for site improvement. We are actively encouraging continued resource contributions from the C. elegans research and education community for the further development of WormClassroom. PMID:17548872

Need versus cost: understanding EHR data migration options.  

PubMed

Over 50% of physician offices and group practices are replacing their electronic health record (EHR) systems. Dissatisfaction with first-generation systems, physician practice mergers, and hospital acquisitions are all driving the move from legacy EHRs to newer, more sophisticated software. With this painful decision comes the same challenge experienced with a medical practice's original EHR implementation--getting data into the new system. However, now practices have decades of data, terabytes of information, and multiple vendors to manage. Time and cost requirements to migrate data from one EHR to another must be weighed against the benefits of physician productivity and continuing patient care. Core areas for practices to consider include staff stress, financial risk, and physician productivity. This article helps practice directors navigate new data-migration decisions when replacing their EHR system. Key considerations and "must-haves" for effective data migration decisions are included. Conversion, vendor neutral archive, and document imaging options are reviewed along with practical best practices for identifying which data should be included in the go-forward EHR. PMID:24765738

Improving HIV/AIDS Knowledge Management Using EHRs  

PubMed Central

Background A primary goal for the development of EHRs and EHR-related technologies should be to facilitate greater knowledge management for improving individual and community health outcomes associated with HIV / AIDS. Most of the current developments of EHR have focused on providing data for research, patient care and prioritization of healthcare provider resources in other areas. More attention should be paid to using information from EHRs to assist local, state, national, and international entities engaged in HIV / AIDS care, research and prevention strategies. Unfortunately the technology and standards for HIV-specific reporting modules are still being developed. Methods: A literature search and review supplemented by the author’s own experiences with electronic health records and HIV / AIDS prevention strategies will be used. This data was used to identify both opportunities and challenges for improving public health informatics primarily through the use of latest innovations in EHRs. Qualitative analysis and suggestions are offered for how EHRs can support knowledge management and prevention strategies associated with HIV infection. Results: EHR information, including demographics, medical history, medication and allergies, immunization status, and other vital statistics can help public health practitioners to more quickly identify at-risk populations or environments; allocate scarce resources in the most efficient way; share information about successful, evidenced-based prevention strategies; and increase longevity and quality of life. Conclusion: Local, state, and federal entities need to work more collaboratively with NGOs, community-based organizations, and the private sector to eliminate barriers to implementation including cost, interoperability, accessibility, and information security.

The Wired Patient: Patterns of Electronic Patient Portal Use Among Patients With Cardiac Disease or Diabetes  

PubMed Central

Background As providers develop an electronic health record–based infrastructure, patients are increasingly using Web portals to access their health information and participate electronically in the health care process. Little is known about how such portals are actually used. Objective In this paper, our goal was to describe the types and patterns of portal users in an integrated delivery system. Methods We analyzed 12 months of data from Web server log files on 2282 patients using a Web-based portal to their electronic health record (EHR). We obtained data for patients with cardiovascular disease and/or diabetes who had a Geisinger Clinic primary care provider and were registered “MyGeisinger” Web portal users. Hierarchical cluster analysis was applied to longitudinal data to profile users based on their frequency, intensity, and consistency of use. User types were characterized by basic demographic data from the EHR. Results We identified eight distinct portal user groups. The two largest groups (41.98%, 948/2258 and 24.84%, 561/2258) logged into the portal infrequently but had markedly different levels of engagement with their medical record. Other distinct groups were characterized by tracking biometric measures (10.54%, 238/2258), sending electronic messages to their provider (9.25%, 209/2258), preparing for an office visit (5.98%, 135/2258), and tracking laboratory results (4.16%, 94/2258). Conclusions There are naturally occurring groups of EHR Web portal users within a population of adult primary care patients with chronic conditions. More than half of the patient cohort exhibited distinct patterns of portal use linked to key features. These patterns of portal access and interaction provide insight into opportunities for electronic patient engagement strategies. PMID:25707036

Such debate brings also to attention the importance of transparent management of electronic health record (EHR) data of deceased patients. In this perspective paper, we look at legal and regulatory policies for EHR data post mortem. We analyze observational research situations using EHR data that do not require institutional review board approval. We propose creation of a deceased subject integrated data repository (dsIDR) as an effective tool for piloting certain types of research projects. We highlight several dsIDR challenges in proving death status, informed consent, obtaining data from payers and healthcare providers and the involvement of next of kin. PMID:23966483

Characteristics of Patient Portals Developed in the Context of Health Information Exchanges: Early Policy Effects of Incentives in the Meaningful Use Program in the United States  

PubMed Central

Background In 2014, the Centers for Medicare & Medicaid Services in the United States launched the second stage of its Electronic Health Record (EHR) Incentive Program, providing financial incentives to providers to meaningfully use their electronic health records to engage patients online. Patient portals are electronic means to engage patients by enabling secure access to personal medical records, communication with providers, various self-management tools, and administrative functionalities. Outcomes of patient portals have mainly been reported in large integrated health systems. This may now change as the EHR Incentive Program enables and supports the use of patient portals in other types of health systems. In this paper, we focus on Health Information Exchanges (HIE): entities that facilitate data exchange within networks of independent providers. Objective In response to the EHR Incentive Program, some Health Information Exchanges in the United States are developing patient portals and offering them to their network of providers. Such patient portals hold high value for patients, especially in fragmented health system contexts, due to the portals’ ability to integrate health information from an array of providers and give patients one access point to this information. Our aim was to report on the early effects of the EHR incentives on patient portal development by HIEs. Specifically, we describe the characteristics of these portals, identify factors affecting adoption by providers during the 2013-2014 time frame, and consider what may be the primary drivers of providers’ adoption of patient portals in the future. Methods We identified four HIEs that were developing patient portals as of spring 2014. We collected relevant documents and conducted interviews with six HIE leaders as well as two providers that were implementing the portals in their practices. We performed content analysis on these data to extract information pertinent to our study objectives. Results Our findings suggest that there are two primary types of patient portals available to providers in HIEs: (1) portals linked to EHRs of individual providers or health systems and (2) HIE-sponsored portals that link information from multiple providers’ EHRs. The decision of providers in the HIEs to adopt either one of these portals appears to be a trade-off between functionality, connectivity, and cost. Our findings also suggest that while the EHR Incentive Program is influencing these decisions, it may not be enough to drive adoption. Rather, patient demand for access to patient portals will be necessary to achieve widespread portal adoption and realization of potential benefits. Conclusions Optimizing patient value should be the main principle underlying policies intending to increase online patient engagement in the third stage of the EHR Incentive Program. We propose a number of features for the EHR Incentive Program that will enhance patient value and thereby support the growth and sustainability of patient portals provided by Health Information Exchanges.

Flexible information storage in MUDR(II) EHR.  

PubMed

An important research task of the EuroMISE Centre is the applied research in the field of electronic health record (EHR) design including electronic medical guidelines and intelligent systems for data mining and decision support. The research in this field was inspired by several European projects. We have proposed a mathematical meta-description of a flexible information storage model based on the experience gathered in cooperation in those projects. In this model, we use two basic structures called a knowledge base and data files. We describe those two structures using the graph theory concepts. Furthermore, we use logical formulas to express conditions that should be valid. Additionally, we present a description of a global system architecture of a 3-tier EHR application with interfaces based on the latest technologies; predominately on Web Services, SOAP, XML, HTTP, CORBA, etc. According to our experience and test results gained from the MUDR EHR usage, we describe an open universal solution, which can be applied as the EHR kernel of hospital information systems. To realize this approach in a daily practice for health professionals we have started a co-operative project with clinical information systems developers. Within that project we are developing a new system for continual shared health care. PMID:16253546

Identifying and mitigating biases in EHR laboratory tests.  

PubMed

Electronic health record (EHR) data show promise for deriving new ways of modeling human disease states. Although EHR researchers often use numerical values of laboratory tests as features in disease models, a great deal of information is contained in the context within which a laboratory test is taken. For example, the same numerical value of a creatinine test has different interpretation for a chronic kidney disease patient and a patient with acute kidney injury. We study whether EHR research studies are subject to biased results and interpretations if laboratory measurements taken in different contexts are not explicitly separated. We show that the context of a laboratory test measurement can often be captured by the way the test is measured through time. We perform three tasks to study the properties of these temporal measurement patterns. In the first task, we confirm that laboratory test measurement patterns provide additional information to the stand-alone numerical value. The second task identifies three measurement pattern motifs across a set of 70 laboratory tests performed for over 14,000 patients. Of these, one motif exhibits properties that can lead to biased research results. In the third task, we demonstrate the potential for biased results on a specific example. We conduct an association study of lipase test values to acute pancreatitis. We observe a diluted signal when using only a lipase value threshold, whereas the full association is recovered when properly accounting for lipase measurements in different contexts (leveraging the lipase measurement patterns to separate the contexts). Aggregating EHR data without separating distinct laboratory test measurement patterns can intermix patients with different diseases, leading to the confounding of signals in large-scale EHR analyses. This paper presents a methodology for leveraging measurement frequency to identify and reduce laboratory test biases. PMID:24727481

During the last 25 years, there have been important developments in visualising the portal vein, in examining its contents, and in measuring the pressure of blood flowing within it. Radiologists have set the scene and now is the time of the scanner. These technical advances have been applied to the diagnosis and treatment of patients with portal hypertension, and many ingenious surgical techniques have been proposed. The problem of successful treatment of the patient with bleeding oesophageal varices and cirrhosis of the liver, however, has not yet been solved. This report discusses the portal vein in terms of pressure, flow, and regeneration factors. Portal hypertension is classified and methods of relief are discussed. PMID:342361

The website is dedicated for school actors (school-level children, teachers, administrative and technical staff, families and local authorities) in order to: - Inform on regulations, on tools for raising awareness for natural and man-made risks and on preventative measures; - Train children, teachers, administrative and technical staff and local authorities; - Produce interactive figures, photographs, videos and games; - Interact with newsgroups and electronic conferences. Together with the EUR-OPA Centre of Nicosia, the project associates several centres of the Major Hazards Agreement network: the European University for the Cultural Heritage (CUEBC) of Ravello (Italy) the European Centre for Risk Prevention (ECRP) of Sofia (Bulgaria), and the European Centre on Geomorphological Hazards (CERG) of Strasbourg (France). "BE-SAFE-NET" is defined as a network among European countries in order to provide e-learning material on natural hazards and risks primarily for schools (secondary school teachers), but also for the public in general. On the webpage, teachers, pupils and the interested public should find information on disaster prevention, preparation, immediate reaction and rehabilitation. The aim of the paper is to present the structure and the organisation of the web-portal following the pilot project focused on landslides and managed by CERG. Some examples of landslides pedagogical material are also presented. The website is structured in five main sections: 1. About the initiative; 2. Definition of common concepts (e.g. hazard (natural and man made), vulnerability, risk, disaster); 3. Pedagogical material (e.g. case studies, photos, learning exercises); 4. Protect yourself; 5. Discussion forum. Based on the experience gained in preparing the landslide pedagogical documents, a clear guidelines for preparing material related to other risks (seismic, floods, snow avalanches, etc, ...) will be helpful for the ultimate goal of the website that is to provide information and material for secondary school teachers in order to prepare associated curricula (and consequently avoiding University grade documents). The proposed scheme for the X specific risk (X is an example of threat) is: 1. What is X? 2. What are the types of X? 3. Why do X occur? 4. Where do X occur, and what were the largest X in the World and in Europe? 5. What could be the consequences of X in terms of human, socio-economic and environmental loss? 6. Can the causes of X be influenced by human behaviour? 8. Can X be predicted? 9. Is there any option to prevent X? 10. Is there any option to mitigate the consequences of X? 11. What to do in case of X? 12. What type of maps on X exists? What is their use? Does the public have access to these maps and from where? For the 12 questions, the contributors were requested to propose a maximum of 20 lines on the main page (so called "first level") and links to specific page (so called "second level") with additional and more detailed information. They were also required to provide for every question additional available material, such as the description of pedagogic case studies, examples of lessons learnt, learning exercises, relevant images, videos and web links). The website is still in progress for further natural and man-made hazards. The landslide pilot section is now nearly complete.

Barriers for Adopting Electronic Health Records (EHRs) by Physicians  

PubMed Central

CONFLICT OF INTEREST: NONE DECLARED Introduction Electronic Medical Records (EMRs) are computerized medical information systems that collect, store and display patient information. They are means to create legible and organized recordings and to access clinical information about individual patients. Despite of the positive effects of the EMRs usage in medical practices, the adoption rate of such systems is still low and meets resistance from physicians. The EHRs represent an essential tool for improving both in the safety and quality of health care, though physicians must actively use these systems to accrue the benefits. This study was unsystematic-review. Aim The aim of this study was to express barriers perceived y physicians to the adoption of the EHRs. Method of the study This study was non-systematic reviewed which the literature was searched on barriers perceived by physicians to the adoption of Electronic Health Records (EHRs) with the help of library, books, conference proceedings, data bank, and also searches engines available at Google, Google scholar. Discussion For our searches, we employed the following keywords and their combinations: physicians, electronic medical record, electronic health record, barrier, and adoption in the searching areas of title, keywords, abstract, and full text. In this study, more than 100 articles and reports were collected and 27 of them were selected based on their relevancy. Electronic health record use requires the presence of certain user and system attributes, support from others, and numerous organizational and environment facilitators. PMID:24058254

The current state of electronic health record (EHR) use in Oklahoma.  

PubMed

There is ample evidence of the positive impact of electronic health records (EHR) on operational efficiencies and quality of care. Yet, growth in the adoption of EHR and sharing of information among providers has been slow. The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 provides financial incentives for eligible providers to adopt and implement EHR. Until now, little information was available regarding the use of EHR in Oklahoma. Sponsored by the Oklahoma Health Information Exchange Trust (OHIET), this study reveals that the frequency of use of EHR among Oklahoma providers is near the national average. Although a large number of Oklahoma physicians have received Medicaid incentive payments for planned adoption, implementation, or upgrade of EHR systems, relatively few eligible providers in Oklahoma have been certified to receive Medicare incentive payments through the Centers for Medicare and Medicaid Services (CMS) and even fewer have actually received these incentive payments.

Bringing electronic patient records into health professional education: towards an integrative framework.  

PubMed

In this paper we discuss our approach for integrating electronic patient records into health professional education. Electronic patient record (EPR) use is increasing globally. The EPR is considered the cornerstone of the modernization and streamlining of healthcare worldwide. However, despite the importance of the EPR, health professional education in much of the world provides health professional students (who will become the practicing health professionals of the future) with limited access or knowledge about the EPR. New ways of exposing students to EPRs will be needed in order to ensure that health professionals will adopt and use this complex technology wisely and effect the positive benefits EPRs are expected to bring to healthcare globally. In this paper we describe: (a) a framework we have developed for integrating EPRs into health professional education and (b) an innovative Web portal, known as the University of Victoria Electronic Health Record (EHR) Educational Portal (which houses a number of EPRs) that can be used to explore the integration of EPRs in health professional education. It is hoped that adoption and use of EPRs will ultimately be improved through the use of the portal to allow students virtual and ubiquitous access to example EPRs, coupled with principled educational approaches for integrating EPR technology into health professional curricula.

Resistance Is Futile: But It Is Slowing the Pace of EHR Adoption Nonetheless  

PubMed Central

Objective The purpose of this study is to reassess the projected rate of Electronic Health Record (EHR) diffusion and examine how the federal government's efforts to promote the use of EHR technology have influenced physicians' willingness to adopt such systems. The study recreates and extends the analyses conducted by Ford et al. 1 The two periods examined come before and after the U.S. Federal Government's concerted activity to promote EHR adoption. Design Meta-analysis and bass modeling are used to compare EHR diffusion rates for two distinct periods of government activity. Very low levels of government activity to promote EHR diffusion marked the first period, before 2004. In 2004, the President of the United States called for a “Universal EHR Adoption” by 2014 (10 yrs), creating the major wave of activity and increased awareness of how EHRs will impact physicians' practices. Measurement EHR adoption parameters—external and internal coefficients of influence—are estimated using bass diffusion models and future adoption rates are projected. Results Comparing the EHR adoption rates before and after 2004 (2001–2004 and 2001–2007 respectively) indicate the physicians' resistance to adoption has increased during the second period. Based on current levels of adoption, less than half the physicians working in small practices will have implemented an EHR by 2014 (47.3%). Conclusions The external forces driving EHR diffusion have grown in importance since 2004 relative to physicians' internal motivation to adopt such systems. Several national forces are likely contributing to the slowing pace of EHR diffusion. PMID:19261931

Secure portal.  

SciTech Connect

There is a need in security systems to rapidly and accurately grant access of authorized personnel to a secure facility while denying access to unauthorized personnel. In many cases this role is filled by security personnel, which can be very costly. Systems that can perform this role autonomously without sacrificing accuracy or speed of throughput are very appealing. To address the issue of autonomous facility access through the use of technology, the idea of a ''secure portal'' is introduced. A secure portal is a defined zone where state-of-the-art technology can be implemented to grant secure area access or to allow special privileges for an individual. Biometric technologies are of interest because they are generally more difficult to defeat than technologies such as badge swipe and keypad entry. The biometric technologies selected for this concept were facial and gait recognition. They were chosen since they require less user cooperation than other biometrics such as fingerprint, iris, and hand geometry and because they have the most potential for flexibility in deployment. The secure portal concept could be implemented within the boundaries of an entry area to a facility. As a person is approaching a badge and/or PIN portal, face and gait information can be gathered and processed. The biometric information could be fused for verification against the information that is gathered from the badge. This paper discusses a facial recognition technology that was developed for the purposes of providing high verification probabilities with low false alarm rates, which would be required of an autonomous entry control system. In particular, a 3-D facial recognition approach using Fisher Linear Discriminant Analysis is described. Gait recognition technology, based on Hidden Markov Models has been explored, but those results are not included in this paper. Fusion approaches for combining the results of the biometrics would be the next step in realizing the secure portal concept.

Portal biliopathy  

PubMed Central

Biliary ductal changes are a common radiological finding in patients with portal hypertension, however only a small percentage of patients (5%-30%) develop symptomatic bile duct obstruction. The exact pathogenesis is not clear, but an involvement of factors such as bile duct compression by venous collaterals, ischemia, and infection is accepted by most authors. Although endoscopic retrograde cholangiopancreatography was used to define and diagnose this condition, magnetic resonance cholangiopancreatography is currently the investigation of choice for diagnosing this condition. Treatment is indicated only for symptomatic cases. Portosystemic shunts are the treatment of choice for symptomatic portal biliopathy. In the majority of patients, the changes caused by biliopathy resolve after shunt surgery, however, 15%-20% patients require a subsequent bilio-enteric bypass or endoscopic management for persistent biliopathy. There is a role for endoscopic therapy in patients with bile duct stones, cholangitis or when portosystemic shunt surgery is not feasible. PMID:23180936

Meeting EHR security requirements: SeAAS approach.  

PubMed

In the last few years, Electronic Health Record (EHR) systems have received a great attention in the literature, as well as in the industry. They are expected to lead to health care savings, increase health care quality and reduce medical errors. This interest has been accompanied by the development of different standards and frameworks to meet EHR challenges. One of the most important initiatives that was developed to solve problems of EHR is IHE (Integrating the Healthcare Enterprise), which adapts the distributed approach to store and manage healthcare data. IHE aims at standardizing the way healthcare systems exchange information in distributed environments. For this purpose it defines several so called Integration Profiles that specify the interactions and the interfaces (Transactions) between various healthcare systems (Actors) or entities. Security was considered also in few profiles that tackled the main security requirements, mainly authentication and audit trails. The security profiles of IHE currently suffer two drawbacks. First, they apply end point security methodology, which has been proven recently to be insufficient and cumbersome in distributed and heterogeneous environment. Second, the current security profiles for more complex security requirements are oversimplified, vague and do not consider architectural design. This recently changed to some extend e.g., with the introduction of newly published white papers regarding privacy [5] and access control [9]. In order to solve the first problem we utilize results of previous studies conducted in the area of security-aware IHE-based systems and the state-of-the-art Security-as-a-Service approach as a convenient methodology to group domain-wide security needs and overcome the end point security shortcomings.

Validating EHR documents: automatic schematron generation using archetypes.  

PubMed

The goal of this study was to examine whether Schematron schemas can be generated from archetypes. The openEHR Java reference API was used to transform an archetype into an object model, which was then extended with context elements. The model was processed and the constraints were transformed into corresponding Schematron assertions. A prototype of the generator for the reference model HL7 v3 CDA R2 was developed and successfully tested. Preconditions for its reusability with other reference models were set. Our results indicate that an automated generation of Schematron schemas is possible with some limitations. PMID:24825691

Generation of ELGA-compatible radiology reports from the Vienna Hospital Association's EHR system.  

PubMed

In the course of setting up the upcoming Austrian national shared EHR system ELGA, adaptors will have to be implemented for the local EHR systems of all participating healthcare providers. These adaptors must be able to transform EHR data from the internal format of the particular local EHR system to the specified format of the ELGA document types and vice versa. In the course of an ongoing diploma thesis we are currently developing a transformation application that shall allow the generation of ELGA-compatible radiology reports from the local EHR system of the Vienna Hospital Association. Up to now a first prototype has been developed that was tested with six radiology reports. It generates technically valid ELGA radiology reports apart from two errors yielded by the ELGA online validator that rather seem to be bugs of the validator. A medical validation of the reports remains to be done. PMID:24825707

Building a logical EHR architecture based on ISO 13606 standard and semantic web technologies.  

PubMed

Among the existing patterns of EHR interoperability, the ISO 13606 standard is an important consideration. It is believed that the use of this norm, in conjunction with semantic technologies, may aid in the construction of a robust architecture, keeping in mind the challenges of semantic interoperability. The objective of this paper is to present a proposal for an EHR architecture, based on ISO 13606 and on the utilization of semantic technologies, for a real EHR scenario. In order to accomplish that, a real EHR scenario is described, as well as its main interoperability requirements and a candidate architecture is proposed to solve the presented challenges of interoperability. The ability of the ISO 13606 EHR reference model to accommodate the scenario was highlighted, together with the support provided by the use of the ontology specification languages--RDF and OWL--in respect to the maintenance of a controlled vocabulary.

National Science Foundation Facilitation of AGU Scientists' K-14 Education and Outreach Activities  

NASA Astrophysics Data System (ADS)

The National Science Foundation encourages the participation of geoscientists in K-14 education and outreach and provides support for that participation through a wide variety of programs. At the most general level, NSF requires that scientists describe the broader impacts of their research in their proposals. While broader impacts are not restricted to education and outreach, this requirement has encouraged many scientists to consider opportunities for K-14 education and outreach. Many NSF-wide programs provide financial support for K-14 education and outreach. Some are long-standing programs like Research Experiences for Undergraduates (REU), which have been used effectively by the geoscience community to introduce undergraduates to our field. Other programs, like CAREER, encourage faculty to develop innovative teaching and curricular approaches and to relate them to their research program. The Education and Human Resources Directorate (EHR) of NSF provides funds for a variety of undergraduate education improvements, and for elementary and secondary education activities. EHR also provides opportunities for informal education that have been used by the geoscience community to develop museum exhibits, IMAX films, television programs, and other high visibility outreach activities. The Directorate for Geosciences (GEO) holds competitions in the Geoscience Education Program and Opportunities to Enhance Diversity in the Geosciences that provide funds focused on development in our own field. Other specialized competitions, like awards associated with the Center for Ocean Science Education Excellence, have targeted the specific K-14 education and outreach needs of portions of our community. Finally, GEO has facilitated the development of the Digital Library for Earth System Education (DLESE) that has established a digital portal to age-appropriate, peer-reviewed curricular material for teachers.

Reasons (Not) to Spend a Few Billions More on EHRs: How Human Factors Research Can Help  

PubMed Central

Summary Objectives To select best medical informatics research works published in 2013 on electronic health record (EHR) adoption, design, and impact, from the perspective of human factors and organizational issues (HFOI). Methods We selected 2,764 papers by querying PubMed (Mesh and TIAB) as well as using a manual search. Papers were evaluated based on pre-defined exclusion and inclusion criteria from their title, keywords, and abstract to select 15 candidate best papers, finally reviewed by 4 external reviewers using a standard evaluation grid. Results Five papers were selected as best papers to illustrate how human factors approaches can improve EHR adoption and design. Among other contributions, these works: (i) make use of the observational and analysis methodologies of social and cognitive sciences to understand clinicians’ attitudes towards EHRs, EHR use patterns, and impact on care processes, workflows, information exchange, and coordination of care; (ii) take into account macro- (environmental) and meso- (organizational) level factors to analyze EHR adoption or lack thereof; (iii) highlight the need for qualitative studies to analyze the unexpected side effects of EHRs on cognitive and work processes as well as the persistent use of paper. Conclusion Selected papers tend to demonstrate that HFOI approaches and methodologies are essential to bridge the gap between EHR systems and end users, and to reduce regularly reported adoption failures and unexpected consequences.

Avoiding the trap in the HITECH Act's incentive timeframe for implementing the EHR.  

PubMed

The American Recovery and Reinvestment Act of 2009, often called the Stimulus Package or the Stimulus Bill, contains a section called the Health Information Technology for Economic and Clinical Health Act (HITECH Act). The HITECH Act made several significant changes to the current HIPAA Security and Privacy Rules and provided funds and incentives to increase the use of electronic health records (EHRs) by eligible physicians and eligible hospitals, as discussed below. The HITECH Act also provides funding for the Office of the National Coordinator for Health Information Technology, which oversees technology standards, implementation strategies, and impact assessment. The goals of the Office of National Coordinator are to achieve use of an EHR for each person in the country by 2014 and to develop a nationwide health information technology infrastructure in support of the first goal. Further, the HITECH Act provides funding for establishing at least 70 regional centers to help promote the adoption of EHRs. These centers are to offer technical assistance, guidance, and information on best practices to help providers achieve meaningful use of EHRs. This article will define the EHR, discuss the HITECH Act EHR stimulus, and explain the problem with the HITECH Act EHR incentive time-frame. PMID:20973376

Meaningful use and the patient portal: patient enrollment, use, and satisfaction with patient portals at a later-adopting center.  

PubMed

Many physicians are adopting patient portals in response to governmental incentives for meaningful use (MU), but the stage 2 requirements for portal use may be particularly challenging for newer electronic health record (EHR) users. This study examined enrollment, use based on MU requirements, and satisfaction in a recently adopting fee-for-service multispecialty system. Between 2010 and 2012, overall portal enrollment increased from 13.2% to 23.1% but varied substantially by physician specialty. In 2013, more than 97% of physicians would have met requirements for a stage 2 MU utilization measure requiring that patients download personal health information, but only 38% of all physicians (87% of primary care physicians [PCPs] and 37% of other specialists) would have met e-mail requirements. Satisfaction with the portal overall and with portal-based e-mails was high. These results suggest that later-adopting PCPs can succeed in providing satisfactory record and e-mail access but specialists may find reaching e-mail thresholds more difficult. PMID:24563085

EHR?Based Medication Support and Nurse?Led Medication Therapy Management: Rationale and Design for a Three?Arm Clinic Randomized Trial  

PubMed Central

Background Patients with chronic conditions often use complex medical regimens. A nurse?led strategy to support medication therapy management incorporated into primary care teams may lead to improved use of medications for disease control. Electronic health record (EHR) tools may offer a lower?cost, less intensive approach to improving medication management. Methods and Results The Northwestern and Access Community Health Network Medication Education Study is a health center–level cluster?randomized trial being conducted within a network of federally qualified community health centers. Health centers have been enrolled in groups of 3 and randomized to (1) usual care, (2) EHR?based medication management tools alone, or (3) EHR tools plus nurse?led medication therapy management. Patients with uncontrolled hypertension who are prescribed ?3 medications of any kind are recruited from the centers. EHR tools include a printed medication list to prompt review at each visit and automated plain?language medication information within the after?visit summary to encourage proper medication use. In the nurse?led intervention, patients receive one?on?one counseling about their medication regimens to clarify medication discrepancies and identify drug?related concerns, safety issues, and nonadherence. Nurses also provide follow?up telephone calls following new prescriptions and periodically to perform medication review. The primary study outcome is systolic blood pressure after 1 year. Secondary outcomes include measures of understanding of dosing instructions, discrepancies between patient?reported medications and the medical record, adherence, and intervention costs. Conclusions The Northwestern and Access Community Health Network Medication Education Study will assess the effects of 2 approaches to support outpatient medication management among patients with uncontrolled hypertension in federally qualified health center settings.

How to successfully select and implement electronic health records (EHR) in small ambulatory practice settings  

PubMed Central

Background Adoption of EHRs by U.S. ambulatory practices has been slow despite the perceived benefits of their use. Most evaluations of EHR implementations in the literature apply to large practice settings. While there are similarities relating to EHR implementation in large and small practice settings, the authors argue that scale is an important differentiator. Focusing on small ambulatory practices, this paper outlines the benefits and barriers to EHR use in this setting, and provides a "field guide" for these practices to facilitate successful EHR implementation. Discussion The benefits of EHRs in ambulatory practices include improved patient care and office efficiency, and potential financial benefits. Barriers to EHRs include costs; lack of standardization of EHR products and the design of vendor systems for large practice environments; resistance to change; initial difficulty of system use leading to productivity reduction; and perceived accrual of benefits to society and payers rather than providers. The authors stress the need for developing a flexible change management strategy when introducing EHRs that is relevant to the small practice environment; the strategy should acknowledge the importance of relationship management and the role of individual staff members in helping the entire staff to manage change. Practice staff must create an actionable vision outlining realistic goals for the implementation, and all staff must buy into the project. The authors detail the process of implementing EHRs through several stages: decision, selection, pre-implementation, implementation, and post-implementation. They stress the importance of identifying a champion to serve as an advocate of the value of EHRs and provide direction and encouragement for the project. Other key activities include assessing and redesigning workflow; understanding financial issues; conducting training that is well-timed and meets the needs of practice staff; and evaluating the implementation process. Summary The EHR implementation experience depends on a variety of factors including the technology, training, leadership, the change management process, and the individual character of each ambulatory practice environment. Sound processes must support both technical and personnel-related organizational components. Additional research is needed to further refine recommendations for the small physician practice and the nuances of specific medical specialties. PMID:19236705

Remote Sensing, New Media and Scientific Literacy for Competence Oriented School Education - A New Integrated Learning Portal  

NASA Astrophysics Data System (ADS)

The project FIS - Fernerkundung in Schulen (German for "Remote Sensing in Schools") - aims at a better integration of remote sensing in school lessons. Respectively, the overall ob-jective is to teach pupils from primary school up to high-school graduation basics and fields of application of remote sensing. Working with remote sensing data opens up new and modern ways of teaching. Therefore many teachers have great interest in the subject "remote sensing", being motivated to integrate this topic into teaching, provided that the curriculum is con-sidered. In many cases, this encouragement fails because of confusing information, which ruins all good intentions. For this reason, a comprehensive and well structured learning portal on the subject remote sensing is developed. This will allow teachers and pupils to have a structured initial understanding of the topic. Recognizing that in-depth use of satellite imagery can only be achieved by the means of computer aided learning methods, a sizeable number of e-Learning contents have been created throughout the last 5 years since the project's kickoff which are now integrated into the learning portal. Three main sections form the backbone of the developed learning portal. 1. The "Teaching Materials" section provides registered teachers with interactive lessons to convey curriculum relevant topics through remote sensing. They are able to use the implemented management system to create classes and enregister pupils, keep track of their progresses and control results of the conducted lessons. Abandoning the functio-nalities of the management system the lessons are also available to non-registered us-ers. 2. Pupils and Teachers can investigate further into remote sensing in the "Research" sec-tion, where a knowledge base alongside a satellite image gallery offer general back-ground information on remote sensing and the provided lessons in a semi interactive manner. 3. The "Analysis Tools" section offers means to further experiment with satellite images by working with predefined sets of Images and Tools. All three sections of the platform are presented exemplary explaining the underlying didactical and technical concepts of the project, showing how they are realized and what their potentials are when put to use in school lessons.

Evaluating the Reliability of EHR-Generated Clinical Outcomes Reports: A Case Study  

PubMed Central

Introduction: Quality incentive programs, such as Meaningful Use, operate under the assumption that clinical quality measures can be reliably extracted from EHRs. Safety Net providers, particularly Federally Qualified Health Centers and Look-Alikes, tend to be high adopters of EHRs; however, recent reports have shown that only about 9% of FQHCs and Look-Alikes were demonstrating meaningful use as of 2013. Our experience working with the Crescent City Beacon Community (CCBC) found that many health centers relied on chart audits to report quality measures as opposed to electronically generating reports directly from their EHRs due to distrust in the data. This paper describes a step-by-step process for improving the reliability of data extracted from EHRs to increase reliability of quality measure reports, to support quality improvement, and to achieve alignment with national clinical quality reporting requirements. Background: Lack of standardization in data capture and reporting within EHRs drives distrust in EHR-reported data. Practices or communities attempting to achieve standardization may look to CCBC’s experience for guidance on where to start and the level of resources required in order to execute a data standardization project. During the time of this data standardization project, CCBC was launching an HIE. Lack of trust in EHR data was a driver for distrust in the HIE data. Methods: We present a case study where a five-step process was used to harmonize measures, reduce data errors, and increase trust in EHR clinical outcomes reports among a community of Safety Net providers using a common EHR. Primary outcomes were the incidence of reporting errors and the potential effect of error types on quality measure percentages. The activities and level of resources required to achieve these results were also documented by the CCBC program. Findings: Implementation of a community-wide data reporting project resulted in measure harmonization, reduced reporting burden, and error reduction in EHR-generated clinical outcomes reporting across participating clinics over a nine-month period. Increased accuracy of clinical outcomes reports provided physicians and clinical care teams with better information to guide their decision-making around quality improvement planning. Discussion: A number of challenges exist to achieving reliable population level quality reporting from EHRs at the practice, vendor, and community levels. Our experience demonstrates that quality measure reporting from EHRs is not a straightforward process, and it requires time and close collaboration between clinics and vendors to improve reliability of reports. Our experience found that practices valued the opportunity and step-wise process to validate their data locally (out of their EHRs) prior to reporting out of the HIE. Conclusion and Next Steps: Communities can achieve higher levels of confidence in quality measure reporting at the population level by establishing collaborative user groups that work with EHR vendors as partners and use technical assistance to build relationships and trust in EHR-generated reports. While this paper describes the first phase of our work around improving standardization and reliability of EHR reports, vendors should continue to explore modifications for improving data capture (at the front-end) via standardized data entry templates.

Method to integrate clinical guidelines into the electronic health record (EHR) by applying the archetypes approach.  

PubMed

Clinical guidelines are documents that assist healthcare professionals, facilitating and standardizing diagnosis, management, and treatment in specific areas. Computerized guidelines as decision support systems (DSS) attempt to increase the performance of tasks and facilitate the use of guidelines. Most DSS are not integrated into the electronic health record (EHR), ordering some degree of rework especially related to data collection. This study's objective was to present a method for integrating clinical guidelines into the EHR. The study developed first a way to identify data and rules contained in the guidelines, and then incorporate rules into an archetype-based EHR. The proposed method tested was anemia treatment in the Chronic Kidney Disease Guideline. The phases of the method are: data and rules identification; archetypes elaboration; rules definition and inclusion in inference engine; and DSS-EHR integration and validation. The main feature of the proposed method is that it is generic and can be applied toany type of guideline. PMID:23920682

A framework for privacy-preserving access to next-generation EHRs.  

PubMed

Although personalized medicine is optimizing the discovery, development and application of therapeutic advances, its full impact on patient and population healthcare management has yet to be realized. Electronic health Records (EHRs), integrated with data from other sources, such as social care data, Personal Healthcare Record (PHR) data and genetic information, are envisaged as having a pivotal role in realizing this individualized approach to healthcare. Thus, a new generation of EHRs will emerge which, in addition to supporting healthcare professionals in making well-informed clinical decisions, shows potential for novel discovery of associations between disease and genetic, environmental or process measures. However, a broad range of ethical, legal and technical reasons may hinder the realization of future EHRs due to potential security and privacy breaches. This paper presents a HIPAA-compliant framework that enables privacy-preserving access to next-generation EHRs. PMID:25160285

Leveraging EHR Data for Outcomes and Comparative Effectiveness Research in Oncology  

PubMed Central

Along with the increasing adoption of electronic health records (EHRs) are expectations that data collected within EHRs will be readily available for outcomes and comparative effectiveness research. Yet the ability to effectively share and reuse data depends on implementing and configuring EHRs with these goals in mind from the beginning. Data sharing and integration must be planned both locally as well as nationally. The rich data transmission and semantic infrastructure developed by the National Cancer Institute (NCI) for research provides an excellent example of moving beyond paper-based paradigms and exploiting the power of semantically robust, network-based systems, and engaging both domain and informatics expertise. Similar efforts are required to address current challenges in sharing EHR data. PMID:22948276

Importance-satisfaction analysis for primary care physicians' perspective on EHRs in Taiwan.  

PubMed

The Taiwan government has been promoting Electronic Health Records (EHRs) to primary care physicians. How to extend EHRs adoption rate by measuring physicians' perspective of importance and performance of EHRs has become one of the critical issues for healthcare organizations. We conducted a comprehensive survey in 2010 in which a total of 1034 questionnaires which were distributed to primary care physicians. The project was sponsored by the Department of Health to accelerate the adoption of EHRs. 556 valid responses were analyzed resulting in a valid response rate of 53.77%. The data were analyzed based on a data-centered analytical framework (5-point Likert scale). The mean of importance and satisfaction of four dimensions were 4.16, 3.44 (installation and maintenance), 4.12, 3.51 (product effectiveness), 4.10, 3.31 (system function) and 4.34, 3.70 (customer service) respectively. This study provided a direction to government by focusing on attributes which physicians found important but were dissatisfied with, to close the gap between actual and expected performance of the EHRs. The authorities should emphasize the potential advantages in meaningful use and provide training programs, conferences, technical assistance and incentives to enhance the national level implementation of EHRs for primary physicians.

Noncirrhotic Portal Hypertension  

PubMed Central

Portal hypertension is characterized by an increase in portal pressure (> 10 mmHg) and could be a result of cirrhosis of the liver or of noncirrhotic diseases. When portal hypertension occurs in the absence of liver cirrhosis, noncirrhotic portal hypertension (NCPH) must be considered. The prognosis of this disease is much better than that of cirrhosis. Noncirrhotic diseases are the common cause of portal hypertension in developing countries, especially in Asia. NCPH is a heterogeneous group of diseases that is due to intrahepatic or extrahepatic etiologies. In general, the lesions in NCPH are vascular in nature and can be classified based on the site of resistance to blood flow. In most cases, these disorders can be explained by endothelial cell lesions, intimal thickening, thrombotic obliterations, or scarring of the intrahepatic portal or hepatic venous circulation. Many different conditions can determine NCPH through the association of these various lesions in various degrees. Many clinical manifestations of NCPH result from the secondary effects of portal hypertension. Patients with NCPH present with upper gastrointestinal bleeding, splenomegaly, ascites after gastrointestinal bleeding, features of hypersplenism, growth retardation, and jaundice due to portal hypertensive biliopathy. Other sequelae include hyperdynamic circulation, pulmonary complications, and other effects of portosystemic collateral circulation like portosystemic encephalopathy. At present, pharmacologic and endoscopic treatments are the treatments of choice for portal hypertension. The therapy of all disorders causing NCPH involves the reduction of portal pressure by pharmacotherapy or portosystemic shunting, apart from prevention and treatment of complications of portal hypertension.

Integration of an OWL-DL knowledge base with an EHR prototype and providing customized information.  

PubMed

When clinicians use electronic health record (EHR) systems, their ability to obtain general knowledge is often an important contribution to their ability to make more informed decisions. In this paper we describe a method by which an external, formal representation of clinical and molecular genetic knowledge can be integrated into an EHR such that customized knowledge can be delivered to clinicians in a context-appropriate manner.Web Ontology Language-Description Logic (OWL-DL) is a formal knowledge representation language that is widely used for creating, organizing and managing biomedical knowledge through the use of explicit definitions, consistent structure and a computer-processable format, particularly in biomedical fields. In this paper we describe: 1) integration of an OWL-DL knowledge base with a standards-based EHR prototype, 2) presentation of customized information from the knowledge base via the EHR interface, and 3) lessons learned via the process. The integration was achieved through a combination of manual and automatic methods. Our method has advantages for scaling up to and maintaining knowledge bases of any size, with the goal of assisting clinicians and other EHR users in making better informed health care decisions.

The Taiwanese method for providing patients data from multiple hospital EHR systems.  

PubMed

Personal Health Record (PHR) systems are growing in popularity and are receiving increased attention from the Biomedical Informatics research community. Information Collection is one PHR research topic and includes system functionality that helps patients retrieve their data from external sources. One of the most potentially useful external sources of information is the data stored in patients' EHRs at medical institutions. PHR systems that support Information Collection from EHR systems are thus interesting to investigate. In this paper we present PHR system that allows patients to receive data from 10 participating hospitals in Taiwan via a USB flash memory device. The overall design goals and architecture for the system are presented. Based on our experiences in designing and implementing the system we propose a three step method for accomplishing Information Collection from EHR systems at medical institutions for similar PHR systems in the future.

Modeling healthcare authorization and claim submissions using the openEHR dual-model approach  

PubMed Central

Background The TISS standard is a set of mandatory forms and electronic messages for healthcare authorization and claim submissions among healthcare plans and providers in Brazil. It is not based on formal models as the new generation of health informatics standards suggests. The objective of this paper is to model the TISS in terms of the openEHR archetype-based approach and integrate it into a patient-centered EHR architecture. Methods Three approaches were adopted to model TISS. In the first approach, a set of archetypes was designed using ENTRY subclasses. In the second one, a set of archetypes was designed using exclusively ADMIN_ENTRY and CLUSTERs as their root classes. In the third approach, the openEHR ADMIN_ENTRY is extended with classes designed for authorization and claim submissions, and an ISM_TRANSITION attribute is added to the COMPOSITION class. Another set of archetypes was designed based on this model. For all three approaches, templates were designed to represent the TISS forms. Results The archetypes based on the openEHR RM (Reference Model) can represent all TISS data structures. The extended model adds subclasses and an attribute to the COMPOSITION class to represent information on authorization and claim submissions. The archetypes based on all three approaches have similar structures, although rooted in different classes. The extended openEHR RM model is more semantically aligned with the concepts involved in a claim submission, but may disrupt interoperability with other systems and the current tools must be adapted to deal with it. Conclusions Modeling the TISS standard by means of the openEHR approach makes it aligned with ISO recommendations and provides a solid foundation on which the TISS can evolve. Although there are few administrative archetypes available, the openEHR RM is expressive enough to represent the TISS standard. This paper focuses on the TISS but its results may be extended to other billing processes. A complete communication architecture to simulate the exchange of TISS data between systems according to the openEHR approach still needs to be designed and implemented. PMID:21992670

Security challenges in integration of a PHR-S into a standards based national EHR.  

PubMed

Health related data provided by patients themselves is expected to play a major role in future healthcare. Data from personal health devices, vaccination records, health diaries or observations of daily living, for instance, is stored in personal health records (PHR) which are maintained by personal health record systems (PHR-S). Combining this information with medical records provided by healthcare providers in electronic health records (EHR) is one of the next steps towards "personal care". Austria currently sets up a nationwide EHR system that incorporates all healthcare providers and is technically based on international standards (IHE, HL7, OASIS, ...). Looking at the expected potential of merging PHR and EHR data it is worth to analyse integration approaches. Although knowing that an integration requires the coordination of processes, information models and technical architectures, this paper specifically focuses on security issues by evaluating general security requirements for a PHR-S (based on HL7 PHR-S FM), comparing them with the information security specifications for the Austrian's national EHR (based on ISO/IES 27000 series) and identifying the main challenges as well as possible approaches.

The Taiwanese method for providing patients data from multiple hospital EHR systems  

Microsoft Academic Search

Personal Health Record (PHR) systems are growing in popularity and are receiving increased attention from the Biomedical Informatics research community. Information Collection is one PHR research topic and includes system functionality that helps patients retrieve their data from external sources. One of the most potentially useful external sources of information is the data stored in patients’ EHRs at medical institutions.

Facilitating secondary use of medical data by using openEHR archetypes.  

PubMed

Clinical trials are of high importance for medical progress. But even though more and more clinical data is available in electronic patient records (EPRs) and more and more electronic data capture (EDC) systems are used in trials, there is still a gap which makes EPR / EDC interoperability difficult and hampers secondary use of medical routine data. The openEHR architecture for Electronic Health Records is based on a two level modeling approach which makes use of 'archetypes'. We want to analyze whether archetypes can help to bridge this gap by building an integrated EPR / EDC system based on openEHR archetypes. We used the 'openEHR Reference Framework and Application' (Opereffa) and existing archetypes for medical data. Furthermore, we developed dedicated archetypes to document study meta data. We developed a first prototype implementation of an archetype based integrated EPR / EDC system. Next steps will be the evaluation of an extended prototype in a real clinical trial scenario. Opereffa was a good starting point for our work. OpenEHR archetypes proved useful for secondary use of health data. PMID:20841857

Portal vein thrombosis.  

PubMed

Portal vein thrombosis (PVT) is the blockage or narrowing of the portal vein by a thrombus. It is relatively rare and has been linked with the presence of an underlying liver disease or prothrombotic disorders. We present a case of a young male who presented with vague abdominal symptoms for approximately one week. Imaging revealed the presence of multiple nonocclusive thrombi involving the right portal vein, the splenic vein, and the left renal vein, as well as complete occlusion of the left portal vein and the superior mesenteric vein. We discuss pathogenesis, clinical presentation, and management of both acute and chronic thrombosis. The presence of PVT should be considered as a clue for prothrombotic disorders, liver disease, and other local and general factors that must be carefully investigated. It is hoped that this case report will help increase awareness of the complexity associated with portal vein thrombosis among the medical community. PMID:25802795

The CEOS Water Portal  

NASA Astrophysics Data System (ADS)

The CEOS Water is a one of the DIAS (Data Integration and Analysis System, http://www.editoria.u-tokyo.ac.jp/projects/dias/?locale=en_US) data distributed systems. The CEOS Water Portal system is distributed in the sense that, while the portal system is located in Tokyo, the data is located in archive centers which are globally distributed. For example, some in-situ data is archived at the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory in Boulder, Colorado, USA. The NWP station time series and global gridded model output data is archived at the Max Planck Institute for Meteorology (MPIM) in cooperation with the World Data Centerfor Climate in Hamburg, Germany. Part of satellite data is archived at DIAS storage at the University of Tokyo, Japan. This portal does not store data. Instead, according to requests made by users on the web page, it retrieves data from distributed data centers on-the-fly and lets them download and see rendered images/plots. Considering the popularity among water related data centers, OpenDAP protocol is mainly being used between this portal and most of data centers. And this portal also is connected to a kind of data brokering system, which is already connected to multiple data centers. For this interface, OpenSearch protocol is being used. The CEOS Water Portal intends to extend its users to include decision makers and officers like river administrators by facilitating a feedback loop. One example of data and information flow centered on the CEOS Water Portal is shown below. (1)Scientists get various data needed for Model Calculation (WEB-DHM, for example) via the portal. (2)Scientists use Model output data and do analysis. (3)Scientists register their use cases into the portal. (4)Decision makers and officers can refer and acquire use cases and data easily. Users can access the CEOS Water Portal system at http://waterportal.ceos.org/.

EHR implementation in a new clinic: a case study of clinician perceptions.  

PubMed

Driven by the Health Information Technology for Economic and Clinical Health (HITECH) Act large numbers of physicians and hospitals are now implementing electronic health records (EHR) with the general expectation that such systems will improve the quality, safety and efficiency of health care services. Studies of conversions from paper to electronic records paint a mixed picture with healthcare providers pleased with some aspects of their EHRs but dissatisfied with others. These prior studies focused on conversions from paper to electronic records. Many provider impressions, therefore, may have been influenced by reactions to the process of being required to change well established patterns. In order to help separate such reactions from true evaluations of the efficacy of the EHR, we decided to survey the providers in a new health center. To insure that the information gathered was not merely anecdotal, we used a well-established format starting with a semi-structured interview which facilitates analysis and recognition of major themes. We included questions around several important areas including workflow, communication, patient satisfaction, productivity, documentation, and quality of care. Ten main themes emerged: impeding patient flow, hindering communication in office, improving communication after the visit, improving tracking of patient care, spending less time with patients, requiring more training, wanting more features, diminishing productivity, appreciating benefits of templates, and enhancing internal communication. The need for better training appeared to be of especially high importance as it impacted several of the other themes. We believe that our study helps validate the similar concerns expressed in studies of transitions from paper to electronic record systems. Our method may be generally useful to other clinics because it facilitates timely recognition of themes, both positive and negative, that clinicians and clinic managers would want to know at an early stage. Prompt knowledge of such developing themes may help to accentuate the positive aspects of the EHR and to prevent negative themes from developing into serious problems that might be considered serious unintended consequences of EHR usage.

The quail anatomy portal.  

PubMed

The Japanese quail is a widely used model organism for the study of embryonic development; however, anatomical resources are lacking. The Quail Anatomy Portal (QAP) provides 22 detailed three-dimensional (3D) models of quail embryos during development from embryonic day (E)1 to E15 generated using optical projection tomography. The 3D models provided can be virtually sectioned to investigate anatomy. Furthermore, using the 3D nature of the models, we have generated a tool to assist in the staging of quail samples. Volume renderings of each stage are provided and can be rotated to allow visualization from multiple angles allowing easy comparison of features both between stages in the database and between images or samples in the laboratory. The use of JavaScript, PHP and HTML ensure the database is accessible to users across different operating systems, including mobile devices, facilitating its use in the laboratory.The QAP provides a unique resource for researchers using the quail model. The ability to virtually section anatomical models throughout development provides the opportunity for researchers to virtually dissect the quail and also provides a valuable tool for the education of students and researchers new to the field.

The Impact of Electronic Patient Portals on Patient Care: A Systematic Review of Controlled Trials  

PubMed Central

Background Modern information technology is changing and provides new challenges to health care. The emergence of the Internet and the electronic health record (EHR) has brought new opportunities for patients to play a more active role in his/her care. Although in many countries patients have the right to access their clinical information, access to clinical records electronically is not common. Patient portals consist of provider-tethered applications that allow patients to electronically access health information that are documented and managed by a health care institution. Although patient portals are already being implemented, it is still unclear in which ways these technologies can influence patient care. Objective To systematically review the available evidence on the impact of electronic patient portals on patient care. Methods A systematic search was conducted using PubMed and other sources to identify controlled experimental or quasi-experimental studies on the impact of patient portals that were published between 1990 and 2011. A total of 1,306 references from all the publication hits were screened, and 13 papers were retrieved for full text analysis. Results We identified 5 papers presenting 4 distinct studies. There were no statistically significant changes between intervention and control group in the 2 randomized controlled trials investigating the effect of patient portals on health outcomes. Significant changes in the patient portal group, compared to a control group, could be observed for the following parameters: quicker decrease in office visit rates and slower increase in telephone contacts; increase in number of messages sent; changes of the medication regimen; and better adherence to treatment. Conclusions The number of available controlled studies with regard to patient portals is low. Even when patient portals are often discussed as a way to empower patients and improve quality of care, there is insufficient evidence to support this assumption. PMID:23183044

Measurement of portal pressure.  

PubMed

Portal pressure is estimated through measuring the hepatic venous pressure gradient (HVPG). The main clinical applications of HVPG measurements include diagnosis, classification, and monitoring of portal hypertension, risk stratification, identification of candidates for liver resection, and monitoring efficacy of ?-adrenergic blockers. Clinically significant portal hypertension is defined as an HVPG of 10 mm Hg or greater. Patients who experience a reduction in the HVPG of 20% or greater or to lower than 12 mm Hg in response to ?-blocker therapy have a markedly decreased risk of bleeding (or rebleeding), ascites, and spontaneous bacterial peritonitis, resulting in improved survival rates.

Portal vein thrombosis.  

PubMed

Portal vein thrombosis (PVT) is a rare event in the general medical setting that commonly complicates cirrhosis with portal hypertension, and can also occur with liver tumors. The diagnosis is often incidental when a thrombus is found in the portal vein on imaging tests. However, PVT may also present with clinical symptoms and can progress to life-threatening complications of ischemic hepatitis, liver failure, and/or small intestinal infarction. This article reviews the pathophysiology of this disorder, with a major focus on PVT in patients with cirrhosis, and presents detailed guidelines on optimal diagnostic and therapeutic strategies.

A cloud-based approach for interoperable electronic health records (EHRs).  

PubMed

We present a cloud-based approach for the design of interoperable electronic health record (EHR) systems. Cloud computing environments provide several benefits to all the stakeholders in the healthcare ecosystem (patients, providers, payers, etc.). Lack of data interoperability standards and solutions has been a major obstacle in the exchange of healthcare data between different stakeholders. We propose an EHR system - cloud health information systems technology architecture (CHISTAR) that achieves semantic interoperability through the use of a generic design methodology which uses a reference model that defines a general purpose set of data structures and an archetype model that defines the clinical data attributes. CHISTAR application components are designed using the cloud component model approach that comprises of loosely coupled components that communicate asynchronously. In this paper, we describe the high-level design of CHISTAR and the approaches for semantic interoperability, data integration, and security. PMID:25055368

Despite substantial progress In EHR adoption, health information exchange and patient engagement remain low in office settings.  

PubMed

The United States is making substantial investments to accelerate the adoption and use of interoperable electronic health record (EHR) systems. Using data from the 2009-13 Electronic Health Records Survey, we found that EHR adoption continues to grow: In 2013, 78 percent of office-based physicians had adopted some type of EHR, and 48 percent had the capabilities required for a basic EHR system. However, we also found persistent gaps in EHR adoption, with physicians in solo practices and non-primary care specialties lagging behind others. Physicians' electronic health information exchange with other providers was limited, with only 14 percent sharing data with providers outside their organization. Finally, we found that 30 percent of physicians routinely used capabilities for secure messaging with patients, and 24 percent routinely provided patients with the ability to view online, download, or transmit their health record. These findings suggest that although EHR adoption continues to grow, policies to support health information exchange and patient engagement will require ongoing attention. PMID:25104827

Incorporating temporal EHR data in predictive models for risk stratification of renal function deterioration.  

PubMed

Predictive models built using temporal data in electronic health records (EHRs) can potentially play a major role in improving management of chronic diseases. However, these data present a multitude of technical challenges, including irregular sampling of data and varying length of available patient history. In this paper, we describe and evaluate three different approaches that use machine learning to build predictive models using temporal EHR data of a patient. The first approach is a commonly used non-temporal approach that aggregates values of the predictors in the patient's medical history. The other two approaches exploit the temporal dynamics of the data. The two temporal approaches vary in how they model temporal information and handle missing data. Using data from the EHR of Mount Sinai Medical Center, we learned and evaluated the models in the context of predicting loss of estimated glomerular filtration rate (eGFR), the most common assessment of kidney function. Our results show that incorporating temporal information in patient's medical history can lead to better prediction of loss of kidney function. They also demonstrate that exactly how this information is incorporated is important. In particular, our results demonstrate that the relative importance of different predictors varies over time, and that using multi-task learning to account for this is an appropriate way to robustly capture the temporal dynamics in EHR data. Using a case study, we also demonstrate how the multi-task learning based model can yield predictive models with better performance for identifying patients at high risk of short-term loss of kidney function.

Costs of health IT: beginning to understand the financial impact of a dental school EHR.  

PubMed

Health Information Technology (Health IT) constitutes an integral component of the operations of most academic dental institutions nowadays. However, the expenses associated with the acquisition and the ongoing maintenance of these complex systems have often been buried among costs for other electronic infrastructure systems, distributed across various cost centers including unmeasured central campus support, covered centrally and therefore difficult to quantify, and spread over years, denying school administrators a clear understanding of the resources that have been dedicated to Health IT. The aim of this study was to understand the financial impact of Health IT at four similar U.S. dental schools: two schools using a purchased Electronic Health Record (EHR), and two schools that developed their own EHR. For these schools, the costs of creating ($2.5 million) and sustaining ($174,000) custom EHR software were significantly higher than acquiring ($500,000) and sustaining ($121,000) purchased software. These results are based on historical data and should not be regarded as a gold standard for what a complete Health IT suite should cost. The presented data are intended to inform school administrators about the myriad of costs associated with Health IT and give them a point of reference when comparing costs or making estimates for implementation projects.

Filling the Gaps in a Fragmented Health Care System: Development of the Health and Welfare Information Portal (ZWIP)  

PubMed Central

Background Current health care systems are not optimally designed to meet the needs of our aging populations. First, the fragmentation of care often results in discontinuity of care that can undermine the quality of care provided. Second, patient involvement in care decisions is not sufficiently facilitated. Objective To describe the development and the content of a program aimed at: (1) facilitating self-management and shared decision making by frail older people and informal caregivers, and (2) reducing fragmentation of care by improving collaboration among professionals involved in the care of frail older people through a combined multidisciplinary electronic health record (EHR) and personal health record (PHR). Methods We used intervention mapping to systematically develop our program in six consecutive steps. Throughout this development, the target populations (ie, professionals, frail older people, and informal caregivers) were involved extensively through their participation in semi-structured interviews and working groups. Results We developed the Health and Welfare Information Portal (ZWIP), a personal, Internet-based conference table for multidisciplinary communication and information exchange for frail older people, their informal caregivers, and professionals. Further, we selected and developed methods for implementation of the program, which included an interdisciplinary educational course for professionals involved in the care of frail older people, and planned the evaluation of the program. Conclusions This paper describes the successful development and the content of the ZWIP as well as the strategies developed for its implementation. Throughout the development, representatives of future users were involved extensively. Future studies will establish the effects of the ZWIP on self-management and shared decision making by frail older people as well as on collaboration among the professionals involved. PMID:23611877

Radioisotopic flow scanning for portal blood flow and portal hypertension  

SciTech Connect

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.

Pregnancy with portal hypertension.  

PubMed

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

Portal Cavernoma during Pregnancy  

PubMed Central

Portal vein thrombosis (PVT) is characterized by the obstruction of the portal venous system. The venous obstruction can be partial or complete and it is caused by thrombogenic conditions (acquired or hereditary) or nonthrombotic factors. The acquired conditions include abdominal inflammation, infections, surgery, myeloproliferative disorders, obesity, oral contraceptive intake, pregnancy, and postpartum period. Occasionally, it is not possible to recognize any overt cause of PVT. During pregnancy there is an increased venous thromboembolism risk mainly in the systemic venous system and the PVT can occur, but there are no data about its exact prevalence, etiology, and outcome. The portal cavernoma is the cavernomatous transformation of the portal vein. It is a consequence of chronic PVT and occurs when myriads of collateral channels develop to bypass the occlusion. The clinical presentation includes hematemesis due to variceal bleeding, ascites or anaemia, and splenomegaly. The cavernous transformation of the portal vein is easily diagnosed by sonography. We report our case of a 32-year-old, gravida 3 para 2, pregnant woman admitted to our hospital at 13 weeks and 1 day of gestation, clinically asymptomatic. Laboratory test, ultrasound, and endoscopic evaluation were negative. After a detailed counseling, the patient decided on termination of pregnancy at 15 weeks and 1 day of gestation. PMID:24392231

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

A systematic review of electronic portal usage among patients with diabetes.  

PubMed

The objectives of this review were (1) to examine characteristics associated with enrollment and utilization of portals among patients with diabetes and (2) to identify barriers and facilitators of electronic patient portal enrollment and utilization. PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were systematically searched for papers reporting original research using quantitative or qualitative methods on characteristics, barriers, and facilitators associated with portal enrollment and utilization among patients with diabetes in the United States. The search was limited to articles published between February 1, 2005 (the date of the national symposium on personal health records) and January 1, 2014. Sixteen articles were identified. Of these, nine were quantitative, three were qualitative, and four used mixed-methods. Several demographic characteristics, having better-controlled diabetes, and providers who engaged in and encouraged portal use were associated with increased portal enrollment and utilization. Barriers to portal enrollment included a lack of patient (1) capacity, (2) desire, and (3) awareness of portal/portal functions. Barriers to portal utilization included (1) patient capacity, (2) lack of provider and patient buy-in to portal benefits, and (3) negative patient experiences using portals. Facilitators of portal enrollment and utilization were providers and family members recommending and engaging in portal use. Improved usability, increased access, educating patients how to use and benefit from portals, and greater endorsement by providers and family members might increase portal enrollment and utilization. As more providers and hospitals offer portals, addressing barriers and leveraging facilitators may help patients with diabetes achieve potential benefits. PMID:24999599

More than half of US hospitals have at least a basic EHR, but stage 2 criteria remain challenging for most.  

PubMed

The national effort to promote the adoption and meaningful use of electronic health records (EHRs) is well under way. However, 2014 marks an important transition: For many hospitals, penalties will be assessed in fiscal year 2015 for failing to meet federal meaningful-use criteria by the end of fiscal year 2014. We used recent data from the American Hospital Association Annual Survey of Hospitals--IT Supplement to assess progress and challenges. EHR adoption among US hospitals continues to rise steeply: 59 percent now have at least a basic EHR. Small and rural hospitals continue to lag behind their better resourced counterparts. Most hospitals are able to meet many of the stage 2 meaningful-use criteria, but only 5.8 percent of hospitals are able to meet them all. Several criteria, including sharing care summaries with other providers and providing patients with online access to their data, will require attention from EHR vendors to ensure that the necessary functions are available and additional effort from many hospitals to make certain that these functionalities are used. Policy makers may want to consider new targeted strategies to ensure that all hospitals move toward meaningful use of EHRs. PMID:25104826

The EHR system ZK-ARCHE automatically generates forms from ISO/EN 13606 archetypes. For this purpose the archetypes are augmented with components of the reference model to achieve so-called "comprehensive archetypes". Data collected via the forms are stored in a list which associates each value with the path of the corresponding comprehensive archetype node coded as W3C XPath. From this list archetype-conformant EHR extracts can be created. The system is embedded with the IHE XDS profile to allow direct data exchange in an environment of distributed data storage.

Serial measurement of portal hemodynamics after partial portal decompression.  

PubMed

In a serial analysis of splanchnic hemodynamics, we compared partial with total portal decompression in 16 alcoholic cirrhotic patients who underwent portacaval shunts for variceal hemorrhage. Partial decompression was achieved with 8 or 10 mm polytetrafluorethylene portacaval H grafts and aggressive collateral ligation. Total decompression was achieved with larger diameter H grafts (12 or 14 mm). Early and follow-up (mean interval, 18 months) postoperative studies of portal hemodynamics included: direct measurement of shunt gradients, scintigraphic quantitation of portal and mesenteric flow distribution to the liver, and a portal and splenic collateral scoring system developed from standardized splenic venography. Partial portal decompression reduced portal pressure by 43% +/- 8% compared with 81% +/- 5% after total decompression (p less than 0.01). Scintigraphy demonstrated that partial decompression provided a greater fraction of portal flow to the liver than did total decompression (57% +/- 9% versus 2% +/- 1% intrahepatic radioactivity) and mesenteric flow distribution (14.5% +/- 5.4% versus 1.2% +/- 0.7%). Only one patient with partial decompression had a significant loss of portal perfusion during the interval studies. Significantly more residual collaterals were visualized in patients with partial decompression than in those with total decompression, and interval studies showed no significant changes from early studies. We conclude that partial decompression maintains higher portal pressures, more residual collaterals, and a greater fraction of portal and mesenteric flow to the liver than does total decompression. A modest but uniform reduction of portal pressure minimizes stimulus for new collateral formation and further shunting of portal flow. PMID:3726761

Anomaly and Signature Filtering Improve Classifier Performance For Detection Of Suspicious Access To EHRs  

PubMed Central

Our objective is to facilitate semi-automated detection of suspicious access to EHRs. Previously we have shown that a machine learning method can play a role in identifying potentially inappropriate access to EHRs. However, the problem of sampling informative instances to build a classifier still remained. We developed an integrated filtering method leveraging both anomaly detection based on symbolic clustering and signature detection, a rule-based technique. We applied the integrated filtering to 25.5 million access records in an intervention arm, and compared this with 8.6 million access records in a control arm where no filtering was applied. On the training set with cross-validation, the AUC was 0.960 in the control arm and 0.998 in the intervention arm. The difference in false negative rates on the independent test set was significant, P=1.6×10?6. Our study suggests that utilization of integrated filtering strategies to facilitate the construction of classifiers can be helpful. PMID:22195129

Comparison of response times of a mobile-web EHRs system using PHP and JSP languages.  

PubMed

Performance evaluation is highly important in the Electronic Health Records (EHRs) system implementation. Response time's measurement can be considered as one manner to make that evaluation. In the e-health field, after the creation of EHRs available through different platforms such as Web and/or mobile, a performance evaluation is necessary. The operation of the system in the right way is essential. In this paper, a comparison of the response times for the MEHRmobile system is presented. The first version uses PHP language with a MySQL database and the second one employs JSP with an eXist database. Both versions have got the same functionalities. In addition to the technological aspects, a significant difference is the way the information is stored. The main goal of this paper is choosing the version which offers better response times. We have created a new benchmark to calculate the response times. Better results have been obtained for the PHP version. Nowadays, this version is being used for specialists from Fundación Intras, Spain. PMID:22706897

IDL Grid Web Portal  

NASA Astrophysics Data System (ADS)

Image Data Language is a software for data analysis, visualization and cross-platform application development. The potentiality of IDL is well-known in the academic scientific world, especially in the astronomical environment where thousands of procedures are developed by using IDL. The typical use of IDL is the interactive mode but it is also possible to run IDL programs that do not require any interaction with the user, submitting them in batch or background modality. Through the interactive mode the user immediately receives images or other data produced in the running phase of the program; in batch or background mode, the user will have to wait for the end of the program, sometime for many hours or days to obtain images or data that IDL produced as output: in fact in Grid environment it is possible to access to or retrieve data only after completion of the program. The work that we present gives flexibility to IDL procedures submitted to the Grid computer infrastructure. For this purpose we have developed an IDL Grid Web Portal to allow the user to access the Grid and to submit IDL programs granting a full job control and the access to images and data generated during the running phase, without waiting for their completion. We have used the PHP technology and we have given the same level of security that Grid normally offers to its users. In this way, when the user notices that the intermediate program results are not those expected, he can stop the job, change the parameters to better satisfy the computational algorithm and resubmit the program, without consuming the CPU time and other Grid resources. The IDL Grid Web Portal allows you to obtain IDL generated images, graphics and data tables by using a normal browser. All conversations from the user and the Grid resources occur via Web, as well as authentication phases. The IDL user has not to change the program source much because the Portal will automatically introduce the appropriate modification before submitting the IDL program to the Grid. When the user wishes, he will be able to check the status of his program and outputs, if any, because the Portal will assign the users a specific and univocal session identification number. This Web portal runs in the Trinacria Grid Virtual Laboratory and fully exploits the power of this grid in terms of CPU and data storage.

Collateral Pathways in Portal Hypertension  

PubMed Central

Presence of portosystemic collateral veins (PSCV) is common in portal hypertension due to cirrhosis. Physiologically, normal portosystemic anastomoses exist which exhibit hepatofugal flow. With the development of portal hypertension, transmission of backpressure leads to increased flow in these patent normal portosystemic anastomoses. In extrahepatic portal vein obstruction collateral circulation develops in a hepatopetal direction and portoportal pathways are frequently found. The objective of this review is to illustrate the various PSCV and portoportal collateral vein pathways pertinent to portal hypertension in liver cirrhosis and EHPVO.

Portal Vein Thrombosis in Cirrhosis  

PubMed Central

Portal vein thrombosis (PVT) is being increasingly recognized in patients with advanced cirrhosis and in those undergoing liver transplantation. Reduced flow in the portal vein is probably responsible for clotting in the spleno-porto-mesenteric venous system. There is also increasing evidence that hypercoagulability occurs in advanced liver disease and contributes to the risk of PVT. Ultrasound based studies have reported a prevalence of PVT in 10–25% of cirrhotic patients without hepatocellular carcinoma. Partial thrombosis of the portal vein is more common and may not have pathophysiological consequences. However, there is high risk of progression of partial PVT to complete PVT that may cause exacerbation of portal hypertension and progression of liver insufficiency. It is thus, essential to accurately diagnose and stage PVT in patients waiting for transplantation and consider anticoagulation therapy. Therapy with low molecular weight heparin and vitamin K antagonists has been shown to achieve complete and partial recanalization in 33–45% and 15–35% of cases respectively. There are however, no guidelines to help determine the dose and therapeutic efficacy of anticoagulation in patients with cirrhosis. Anticoagulation therapy related bleeding is the most feared complication but it appears that the risk of variceal bleeding is more likely to be dependent on portal pressure rather than solely related to coagulation status. TIPS has also been reported to restore patency of the portal vein. Patients with complete PVT currently do not form an absolute contraindication for liver transplantation. Thrombectomy or thromboendovenectomy is possible in more than 75% of patients followed by anatomical end-to-end portal anastomosis. When patency of the portal vein and/or superior mesenteric vein is not achieved, only non-anatomical techniques (reno-portal anastomosis or cavo-portal hemitransposition) can be performed. These techniques, which do not fully reverse portal hypertension, are associated with higher morbidity and mortality risks in the short term. PMID:25755579

Management of portal hypertension  

PubMed Central

Treatment of portal hypertension is evolving based on randomised controlled trials. In acute variceal bleeding, prophylactic antibiotics are mandatory, reducing mortality as well as preventing infections. Terlipressin or somatostatin combined with endoscopic ligation or sclerotherapy is the best strategy for control of bleeding but there is no added effect of vasoactive drugs on mortality. Non-selective ß-blockers are the first choice therapy for both secondary and primary prevention; if contraindications or intolerance to ß-blockers are present then band ligation should be used. Novel therapies target the increased intrahepatic resistance caused by microcirculatory intrahepatic deficiency of nitric oxide and contraction of activated intrahepatic stellate cells.

Development and Psychometric Qualities of the SEIPS Survey to Evaluate CPOE/EHR Implementation in ICUs.  

PubMed

Health Information Technology (IT) implementation can fail or meet high levels of user resistance for a variety of reasons, including lack of attention to users' needs and the significant workflow changes induced and required by the technology. End-user satisfaction is a critical factor in health IT implementation. In this paper we describe the process of developing and testing a questionnaire to evaluate health IT implementation, in particular Computerized Provider Order Entry (CPOE) and Electronic Health Record (EHR) technologies. Results showed evidence for the validity and reliability of the questionnaire. The Systems Engineering Initiative for Patient Safety (SEIPS) questionnaire is relatively easy to administer and allows researchers to evaluate different aspects of health IT implementation. Results of this research can be used for benchmarking results of future studies evaluating health IT implementation. PMID:21475612

Portal monitoring technology control process  

SciTech Connect

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.

Non-cirrhotic portal hypertension.  

PubMed

Non-cirrhotic portal hypertension (NCPH) encompasses a wide range of disorders, primarily vascular in origin, presenting with portal hypertension (PHT), but with preserved liver synthetic functions and near normal hepatic venous pressure gradient (HVPG). Non-cirrhotic portal fibrosis/Idiopathic PHT (NCPF/IPH) and extrahepatic portal venous obstruction (EHPVO) are two prototype disorders in the category. Etiopathogenesis in both of them centers on infections and prothrombotic states. Presentation and management strategies focus on repeated well tolerated episodes of variceal bleed and moderate to massive splenomegaly and other features of PHT. While the long-term prognosis is generally good in NCPF, portal biliopathy and parenchymal extinction after prolonged PHT makes outcome somewhat less favorable in EHPVO. While hepatic schistosomiasis, congenital hepatic fibrosis and nodular regenerative hyperplasia have their distinctive features, they often present with NCPH. PMID:24679506

Building a Stückelberg portal  

NASA Astrophysics Data System (ADS)

We construct explicit string theory models realizing the recently proposed "Stückelberg Portal" scenario, a framework for building Z' mediation models without the need to introduce unwanted exotic matter charged under the Standard Model. This scenario can be viewed purely field-theoretically, although it is particularly well motivated from string theory. By analyzing carefully the Stückelberg couplings between the Abelian gauge bosons and the RR axions, we construct the first global intersecting brane models which extend the Standard Model with a genuine hidden sector, to which it is nonetheless connected via U(1) mass mixings. Utilizing the explicit models we construct, we discuss some broad phenomenological properties and experimental implications of this scenario such as Z - Z' mixings, dark matter stability and relic density, and supersymmetry mediation. With an appropriate confining hidden sector, our setup also provides a minimal realization of the hidden valley scenario. We further explore the possibility of obtaining small Z' masses from a large ensemble of U(1) bosons. Related to the Stückelberg portal are two mechanisms that connect the visible and the hidden sectors, namely mediation by non-perturbative operators and the hidden photon scenario, on which we briefly comment.

Electronic health record training in undergraduate medical education: bridging theory to practice with curricula for empowering patient- and relationship-centered care in the computerized setting.  

PubMed

While electronic health record (EHR) use is becoming state-of-the-art, deliberate teaching of health care information technology (HCIT) competencies is not keeping pace with burgeoning use. Medical students require training to become skilled users of HCIT, but formal pedagogy within undergraduate medical education (UME) is sparse. How can medical educators best meet the needs of learners while integrating EHRs into medical education and practice? How can they help learners preserve and foster effective communication skills within the computerized setting? In general, how can UME curricula be devised for skilled use of EHRs to enhance rather than hinder provision of effective, humanistic health care?Within this Perspective, the authors build on recent publications that "set the stage" for next steps: EHR curricula innovation and implementation as concrete embodiments of theoretical underpinnings. They elaborate on previous calls for maximizing benefits and minimizing risks of EHR use with sufficient focus on physician-patient communication skills and for developing core competencies within medical education. The authors describe bridging theory into practice with systematic longitudinal curriculum development for EHR training in UME at their institution, informed by Kern and colleagues' curriculum development framework, narrative medicine, and reflective practice. They consider this innovation within a broader perspective-the overarching goal of empowering undergraduate medical students' patient- and relationship-centered skills while effectively demonstrating HCIT-related skills.

Are Meaningful Use Stage 2 certified EHRs ready for interoperability? Findings from the SMART C-CDA Collaborative  

PubMed Central

Background and objective Upgrades to electronic health record (EHR) systems scheduled to be introduced in the USA in 2014 will advance document interoperability between care providers. Specifically, the second stage of the federal incentive program for EHR adoption, known as Meaningful Use, requires use of the Consolidated Clinical Document Architecture (C-CDA) for document exchange. In an effort to examine and improve C-CDA based exchange, the SMART (Substitutable Medical Applications and Reusable Technology) C-CDA Collaborative brought together a group of certified EHR and other health information technology vendors. Materials and methods We examined the machine-readable content of collected samples for semantic correctness and consistency. This included parsing with the open-source BlueButton.js tool, testing with a validator used in EHR certification, scoring with an automated open-source tool, and manual inspection. We also conducted group and individual review sessions with participating vendors to understand their interpretation of C-CDA specifications and requirements. Results We contacted 107 health information technology organizations and collected 91 C-CDA sample documents from 21 distinct technologies. Manual and automated document inspection led to 615 observations of errors and data expression variation across represented technologies. Based upon our analysis and vendor discussions, we identified 11 specific areas that represent relevant barriers to the interoperability of C-CDA documents. Conclusions We identified errors and permissible heterogeneity in C-CDA documents that will limit semantic interoperability. Our findings also point to several practical opportunities to improve C-CDA document quality and exchange in the coming years. PMID:24970839

MyHealthAtVanderbilt: policies and procedures governing patient portal functionality  

PubMed Central

Explicit guidelines are needed to develop safe and effective patient portals. This paper proposes general principles, policies, and procedures for patient portal functionality based on MyHealthAtVanderbilt (MHAV), a robust portal for Vanderbilt University Medical Center. We describe policies and procedures designed to govern popular portal functions, address common user concerns, and support adoption. We present the results of our approach as overall and function-specific usage data. Five years after implementation, MHAV has over 129?800 users; 45% have used bi-directional messaging; 52% have viewed test results and 45% have viewed other medical record data; 30% have accessed health education materials; 39% have scheduled appointments; and 29% have managed a medical bill. Our policies and procedures have supported widespread adoption and use of MHAV. We believe other healthcare organizations could employ our general guidelines and lessons learned to facilitate portal implementation and usage. PMID:21807648

The need to know the history of the use of digital patient data, in particular the EHR.  

PubMed

The purpose of this article is to explore the need for the possibility to reconstruct electronic medical data, in particular the electronic health record (EHR) as they have been or could have been presented to a specified health care professional at a specified moment in the past. The approach taken is that first the need for such functionality is discussed with attention to the differences between electronic records and paper records in this respect. Next the architectural and technical consequences of the implementation of the functionality are considered. The article concludes that such functionality is needed for medical audit, self assessment and handling of complaints. It further concludes that it is far from easy to implement the functionality. If the health care community underwrites the need for such functionality this will have a significant impact on the architecture of medical information systems and the (distributed) EHR. It is recommended that the professional associations and the governments, in collaboration with WHO, take a position on the need to be able to reconstruct the contents of the EHR. IMIA could take the lead in that process. PMID:17067851

Evaluation of matched control algorithms in EHR-based phenotyping studies: a case study of inflammatory bowel disease comorbidities.  

PubMed

The success of many population studies is determined by proper matching of cases to controls. Some of the confounding and bias that afflict electronic health record (EHR)-based observational studies may be reduced by creating effective methods for finding adequate controls. We implemented a method to match case and control populations to compensate for sparse and unequal data collection practices common in EHR data. We did this by matching the healthcare utilization of patients after observing that more complete data was collected on high healthcare utilization patients vs. low healthcare utilization patients. In our results, we show that many of the anomalous differences in population comparisons are mitigated using this matching method compared to other traditional age and gender-based matching. As an example, the comparison of the disease associations of ulcerative colitis and Crohn's disease show differences that are not present when the controls are chosen in a random or even a matched age/gender/race algorithm. In conclusion, the use of healthcare utilization-based matching algorithms to find adequate controls greatly enhanced the accuracy of results in EHR studies. Full source code and documentation of the control matching methods is available at https://community.i2b2.org/wiki/display/conmat/. PMID:25196084

The EHR-ARCHE project: Satisfying clinical information needs in a Shared Electronic Health Record System based on IHE XDS and Archetypes?  

PubMed Central

Purpose While contributing to an improved continuity of care, Shared Electronic Health Record (EHR) systems may also lead to information overload of healthcare providers. Document-oriented architectures, such as the commonly employed IHE XDS profile, which only support information retrieval at the level of documents, are particularly susceptible for this problem. The objective of the EHR-ARCHE project was to develop a methodology and a prototype to efficiently satisfy healthcare providers’ information needs when accessing a patient's Shared EHR during a treatment situation. We especially aimed to investigate whether this objective can be reached by integrating EHR Archetypes into an IHE XDS environment. Methods Using methodical triangulation, we first analysed the information needs of healthcare providers, focusing on the treatment of diabetes patients as an exemplary application domain. We then designed ISO/EN 13606 Archetypes covering the identified information needs. To support a content-based search for fine-grained information items within EHR documents, we extended the IHE XDS environment with two additional actors. Finally, we conducted a formative and summative evaluation of our approach within a controlled study. Results We identified 446 frequently needed diabetes-specific information items, representing typical information needs of healthcare providers. We then created 128 Archetypes and 120 EHR documents for two fictive patients. All seven diabetes experts, who evaluated our approach, preferred the content-based search to a conventional XDS search. Success rates of finding relevant information was higher for the content-based search (100% versus 80%) and the latter was also more time-efficient (8–14 min versus 20 min or more). Conclusions Our results show that for an efficient satisfaction of health care providers’ information needs, a content-based search that rests upon the integration of Archetypes into an IHE XDS-based Shared EHR system is superior to a conventional metadata-based XDS search.

The Higgs Portal Above Threshold  

E-print Network

The discovery of the Higgs boson opens the door to new physics interacting via the Higgs Portal, including motivated scenarios relating to baryogenesis, dark matter, and electroweak naturalness. We systematically explore the collider signatures of singlet scalars produced via the Higgs Portal at the 14 TeV LHC and a prospective 100 TeV hadron collider. We focus on the challenging regime where the scalars are too heavy to be produced in the decays of an on-shell Higgs boson, and instead are produced primarily via an off-shell Higgs. Assuming these scalars escape the detector, promising channels include missing energy in association with vector boson fusion, monojets, and top pairs. We forecast the sensitivity of searches in these channels at $\\sqrt{s} = 14$ & 100 TeV and compare collider reach to the motivated parameter space of singlet-assisted electroweak baryogenesis, Higgs Portal dark matter, and neutral naturalness.

The Reusable Astronomy Portal (TRAP)  

NASA Astrophysics Data System (ADS)

The Reusable Astronomy Portal (TRAP) aims to provide a common platform for rapidly deploying Astronomy Archives to the web. TRAP is currently under development for both the VAO Data Discovery Portal and the MAST Multi-Mission Portal (Figure 1). TRAP consists of 2 major software packages: the TRAP Client and the TRAP Server. The TRAP framework allows developers to deploy the Server, connect to data resources, then focus on building custom tools for the Client. TRAP is built upon proven industry technologies including the Ext/JS JavaScript Component Library, Mono.NET Web Services, and JSON message based APIs. The multi-layered architecture of TRAP decouples each layer: Client, Service and Data Access, enabling each to evolve independently over time. Although currently deployed to provide astronomy science data access, the TRAP architecture is flexible enough to thrive in any distributed data environment.

Factors influencing nursing students' acceptance of electronic health records for nursing education (EHRNE) software program.  

PubMed

The Institute of Medicine (IOM) and the Health Information Technology Act (2009) in America had recommended that electronic health records (EHRs) should be fully adopted by 2014. This has urged educational institutions to prepare healthcare professionals to be competent in using electronic health records (EHRs) while they are in schools. To equip nursing students with competency in using EHRs, an electronic health record for nursing education (EHRNE) has been developed and integrated it into nursing curricula. The purposes of the study were to investigate the factors influencing nursing students' acceptance of the EHRs in nursing education using the extended Technology Acceptance Model with self-efficacy as a conceptual framework. The study is a descriptive study design using self-reported questionnaires with 212 student participants. The IBM SPSS and AMOS 22.0 were used to analyze the data. The results showed that attitude toward using the EHRNE was the most influential factor on students' acceptance. The preliminary findings suggested that to enhance the students' acceptance of the EHRNE, cultivation of a positive attitude toward using this EHR as well as increasing the perceived usefulness is very important. Also, the study's framework could be used in guiding learning health informatics and be applied to nursing students. PMID:24947068

Evaluation of a flowchart-based EHR query system: a case study of RetroGuide.  

PubMed

Provision of query systems which are intuitive for non-experts has been recognized as an important informatics challenge. We developed a prototype of a flowchart-based analytical framework called RetroGuide that enables non-experts to formulate query tasks using a step-based, patient-centered paradigm inspired by workflow technology. We present results of the evaluation of RetroGuide in comparison to Structured Query Language (SQL) in laboratory settings using a mixed method design. We asked 18 human subjects with limited database experience to solve query tasks in RetroGuide and SQL, and quantitatively compared their test scores. A follow-up questionnaire was designed to compare both technologies qualitatively and investigate RetroGuide technology acceptance. The quantitative comparison of test scores showed that the study subjects achieved significantly higher scores using the RetroGuide technology. Qualitative study results indicated that 94% of subjects preferred RetroGuide to SQL because RetroGuide was easier to learn, it better supported temporal tasks, and it seemed to be a more logical modeling paradigm. Additional qualitative evaluation results, based on a technology acceptance model, suggested that a fully developed RetroGuide-like technology would be well accepted by users. Our study is an example of a structure validation study of a prototype query system, results of which provided significant guidance in further development of a novel query paradigm for EHR data. We discuss the strengths and weakness of our study design and results, and their implication for future evaluations of query systems in general. PMID:19560553

As a countermeasure to portal tumor thrombi, which are a serious danger in liver cancer, we did portal vein embolization (PVE) during percutaneous transhepatic portography. Our 21 patients later underwent hepatic resection. After PVE, portal pressure increased and there was slight liver function damage, but this procedure was safer than transarterial embolization (TAE). We examined the pathologic specimens to view

Surgical management of portal hypertension.  

PubMed Central

Portal hypertension is frequently complicated by upper gastrointestinal tract bleeding and ascites. Hemorrhage from esophageal varices is the most common cause of death from portal hypertension. Medical treatment, including resuscitation, vasoactive drugs, and endoscopic sclerosis, is the preferred initial therapy. Patients with refractory hemorrhage frequently are referred for immediate surgical intervention (usually emergency portacaval shunt). An additional cohort of patients with a history of at least 1 episode of variceal hemorrhage is likely to benefit from elective shunt operations. Shunt operations are classified as total, partial, or selective shunts based on their hemodynamic characteristics. Angiographically created shunts have been introduced recently as an alternative to operative shunts in certain circumstances. Devascularization of the esophagus or splenectomy is done for specific indications. Medically intractable ascites is a separate indication for surgical intervention. Liver transplantation has been advocated for patients whose portal hypertension is a consequence of end-stage liver disease. In the context of an increasingly complex set of treatment options, we present an overview of surgical therapy for complications of portal hypertension. PMID:7618313

An EHR prototype using structured ISO/EN 13606 documents to respond to identified clinical information needs of diabetes specialists: a controlled study on feasibility and impact.  

PubMed

Cross-institutional longitudinal Electronic Health Records (EHR), as introduced in Austria at the moment, increase the challenge of information overload of healthcare professionals. We developed an innovative cross-institutional EHR query prototype that offers extended query options, including searching for specific information items or sets of information items. The available query options were derived from a systematic analysis of information needs of diabetes specialists during patient encounters. The prototype operates in an IHE-XDS-based environment where ISO/EN 13606-structured documents are available. We conducted a controlled study with seven diabetes specialists to assess the feasibility and impact of this EHR query prototype on efficient retrieving of patient information to answer typical clinical questions. The controlled study showed that the specialists were quicker and more successful (measured in percentage of expected information items found) in finding patient information compared to the standard full-document search options. The participants also appreciated the extended query options. PMID:23304308

Unitarity Constraints on Higgs Portals  

E-print Network

Dark matter that was once in thermal equilibrium with the Standard Model is generally prohibited from obtaining all of its mass from the electroweak phase transition. This implies a new scale of physics and mediator particles to facilitate dark matter annihilation. In this work, we focus on dark matter that annihilates through a generic Higgs portal. We show how partial wave unitarity places an upper bound on the mass of the mediator (or dark) Higgs when its mass is increased to be the largest scale in the effective theory. For models where the dark matter annihilates via fermion exchange, an upper bound is generated when unitarity breaks down around 8.5 TeV. Models where the dark matter annihilates via fermion and higgs boson exchange push the bound to 45.5 TeV. We also show that if dark matter obtains all of its mass from a new symmetry breaking scale that scale is also constrained. We improve these constraints by requiring perturbativity in the Higgs sector up to each unitarity bound. In this limit, the bounds on the dark symmetry breaking vev and the dark Higgs mass are now 2.4 and 3 TeV, respectively, when the dark matter annihilates via fermion exchange. When dark matter annihilates via fermion and higgs boson exchange, the bounds are now 12 and 14.2 TeV, respectively. The available parameter space for Higgs portal dark matter annihilation is outlined. We also show how the bounds are improved if Higgs portal dark matter is only a fraction of the observed relic abundance. Finally, we discuss how to apply these arguments to other dark matter scenarios and discuss prospects for direct detection and future collider searches. If the Higgs portal is responsible for dark matter annihilation, planned direct detection experiments will cover almost all the parameter space. The ILC and/or VLHC, however, is needed to establish the Higgs portal mechanism.

Developing Interoperable Air Quality Community Portals  

NASA Astrophysics Data System (ADS)

Web portals are intended to provide consolidated discovery, filtering and aggregation of content from multiple, distributed web sources targeted at particular user communities. This paper presents a standards-based information architectural approach to developing portals aimed at air quality community collaboration in data access and analysis. An important characteristic of the approach is to advance beyond the present stand-alone design of most portals to achieve interoperability with other portals and information sources. We show how using metadata standards, web services, RSS feeds and other Web 2.0 technologies, such as Yahoo! Pipes and del.icio.us, helps increase interoperability among portals. The approach is illustrated within the context of the GEOSS Architecture Implementation Pilot where an air quality community portal is being developed to provide a user interface between the portals and clearinghouse of the GEOSS Common Infrastructure and the air quality community catalog of metadata and data services.

The ADRICOSM STAR GeoPortal  

NASA Astrophysics Data System (ADS)

From Stockholm (1972) to Rio de Janeiro (1992) and to Johannesburg (2002), environmental protection objectives are related to the principles of sustainable development. This includes the following important components: participation, information, communication, training (capacity building) and education. Better information ensure more participation from individuals, and allows citizens to take part in many different actions that can influence the policy process. Participation to political decisions need access to reliable and quality controlled information. The ADRICOSM Portal was developed in order to manage data diversity, provide access to any kind of product, provide metadata completeness and accuracy. The product, as defined in ADRICOSM, is anything that can be offered to a client and that might satisfy a want or need. This implied the implementation of services that was taking into consideration the diversity of the objects to be provided to users: observations, model outputs, maps, etc. The implementation of the portal was based on two metadata levels: 1. Directory level - consisting of broad descriptions of the contents of data sets; used to locate data sets of potential interest and 2. Data level - consisting of the actual data objects. The portal was developed as a simplified front end for the partners data management systems, giving emphasis on federated access points focused on thematic aspects. This was based on the idea that specialized customer-related access points can be better carried out by delegated teams of experts who know the needs of different customers, define the user software which is most suited to them. The data management systems provide facilities for two data tracks, one in real-time (or near-realtime) and one in delayed mode. Both tracks are based on the same data sources and transmission systems, but the data follow different routes and are processed differently depending on user requirements. The real-time data and model products are checked after first use for up-grading and additional quality control to ensure that all relevant data are preserved for final archival. In summary the ADRICOSM Geoportal has: - the objective to support data exchange in Adricosm Star and the implementation of tools to facilitate the access to data and information through thematic portals, converting individual data provider systems into a federation. - provide the necessary information to users on content of data that can be accessed in the federated systems. The portal is organised in three modules and a catalog. The module 1 has been realized by giving information on the project and objectives, data policy, reasons to provide products and services, link to the themes. Skilled people can jump to the data/products/services provider by clicking on the geographical map. Module 2 is providing more specific information on centers providing data/products/services. Module 3 is providing a direct access to partners product. It contains a short description of the products and a link. Module 4 contain the catalog for each partner product and is based on What, Where, When and How.

How to measure the QoS of a web-based EHRs system: development of an instrument.  

PubMed

The quality of service (QoS) can be treated as a set of concepts whose satisfaction/dissatisfaction generates a global positive/negative vision about the service provided by any application. The different nature of the services and its features require an analysis of the factors that have the greatest influence on the users' opinion and, therefore, measuring the quality of service in each application requires a specific instrument. This paper will introduce an instrument to measure the QoS offered to users by a general Web application for Electronic Health Records (EHRs). The collection of opinions from a pilot sample and the performance of an explanatory factor analysis will bring together the factors that best sum up the quality of an EHRs application. Subsequently, a confirmatory factor analysis will be performed to make the study reliable and, as its name suggests, to confirm that indeed the structure of the instrument developed measures the QoS in accordance with the requirements of the users.

A portal apparatus for screening objects or persons for the presence of trace amounts of chemical substances such as illicit drugs or explosives. The apparatus has a test space, in which a person may stand, defined by two generally upright sides spanned by a horizontal transom. One or more fans in the transom generate a downward air flow (uni-directional) within the test space. The air flows downwardly from a high pressure upper zone, past the object or person to be screened. Air moving past the object dislodges from the surface thereof both volatile and nonvolatile particles of the target substance. The particles are entrained into the air flow which continues flowing downward to a lower zone of reduced pressure, where the particle-bearing air stream is directed out of the test space and toward preconcentrator and detection components. The sides of the portal are specially configured to partially contain and maintain the air flow.

Z-portal dark matter  

E-print Network

We propose to generalize the extensions of the Standard Model where the $Z$ boson serves as a mediator between the Standard Model sector and the dark sector $\\chi$. We show that, like in the Higgs portal case, the combined constraints from the recent direct searches restrict severely the nature of the coupling of the dark matter to the $Z$ boson and set a limit $m_\\chi \\gtrsim 200$ GeV (except in a very narrow region around the $Z-$pole region). Using complementarity between spin dependent, spin independent and FERMI limits, we predict the nature of this coupling, more specifically the axial/vectorial ratio that respects a thermal dark matter coupled through a $Z$-portal while not being excluded by the current observations. We also show that the next generation of experiments of the type LZ or XENON1T will test Z-portal scenario for dark matter mass up to 2 TeV. The condition of a thermal dark matter naturally predicts the spin--dependent scattering cross section on the neutron to be $\\sigma^{SD}_{\\chi n} \\simeq 10^{-40} \\mrm{cm^2}$, which then becomes a clear prediction of the model and a signature testable in the near future experiments.

Imaging of Portal Cavernoma Cholangiopathy  

PubMed Central

Portal cavernoma cholangiopathy (PCC) refers to the biliary changes which occur in the setting of extrahepatic portal vein obstruction and secondary portal cavernoma formation. The main radiological findings include the vascular changes in the form of portosystemic collaterals and biliary changes in the form of extrinsic impressions and strictures. Till date, conventional cholangiography has been the gold standard for the diagnosis of PCC. However, it is an invasive procedure and is associated with complications. At present there is a transition towards non-invasive modalities like ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). The recent advances in these modalities provide an excellent delineation of both the vascular and the biliary changes non-invasively in a short time. The findings of PCC using these newer modalities are not so well described in literature. The findings of PCC also overlap with malignant conditions of biliary tract such as cholangiocarcinoma and compression of biliary tract by malignant adenopathies. In this article we describe the vascular and biliary changes associated with PCC on US, CT and MRI. We also describe the imaging findings using each modality along with their advantages and disadvantages. PMID:25755595

Portal vein stenting to treat portal vein tumor thrombus in hepatocellular carcinoma.  

PubMed

Tumor thrombus in the portal vein is refractory to therapy and a serious negative prognostic factor in hepatocellular carcinoma. We describe herein the case of a patient in whom an expandable metallic stent was successfully employed to treat portal vein tumor thrombus by restoring blood flow. An expandable metallic stent was implanted in a patient with severe main portal vein stenosis caused by tumor thrombus protruding from the left portal vein branch. Immediately after stent placement, the stenotic lesion was effectively dilated, the portal blood flow restored, and portal hypertension relieved. Angiography, computed tomography, and doppler ultrasonography done 2 months after the stent placement revealed continued patency of the portal vein. Thus, intraportal placement of an expandable metallic stent appears to be an effective treatment for major portal vein tumor PMID:11252736

[Portal vein embolization prior to liver surgery].  

PubMed

Portal vein embolization is performed with the intention to occlude the portal veins to liver segments with malignancies and direct the portal flow to the healthy part (usually the left lobe) of the liver. Thus, hyperperfusion through the non-embolized part of the liver will create hyperplasia and hyperfunction, which allow extensive liverresection at a later stage in patients where it otherwise would have been contradictory to operate because of too small volume of the residual liver.

Noncirrhotic portal fibrosis after Wilms' tumor therapy  

SciTech Connect

A 9-yr-old girl developed massive hemorrhage from esophageal varices 2 yr after combined modality therapy for Wilms' tumor. Evaluation showed a patent extrahepatic portal venous system and an elevated splenic pulp pressure. In contrast to previous reports of hepatopathy after irradiation injury, histologic sections of the liver did not demonstrate occlusion of the central veins, but rather a diffuse obliteration of intrahepatic portal venous radicles. This pattern of noncirrhotic portal fibrosis has not been described following antitumor therapy.

Evaluating alert fatigue over time to EHR-based clinical trial alerts: findings from a randomized controlled study. | accrualnet.cancer.gov  

Cancer.gov

The authors hypothesized that repeated exposure to clinical trial alerts (a recruitment decision tool based on matches of trial criteria with EHRs) results in "alert fatigue," defined as a reduction to responses to alerts and subsequent referrals to trials. At the end of the study period, response rates remained relatively high, while greater reductions in referrals were recorded.

Extension of GWAS results for lipid-related phenotypes to extreme obesity using electronic health record (EHR) data and the Metabochip.  

PubMed

A variety of health-related data are commonly deposited into electronic health records (EHRs), including laboratory, diagnostic, and medication information. The digital nature of EHR data facilitates efficient extraction of these data for research studies, including genome-wide association studies (GWAS). Previous GWAS have identified numerous SNPs associated with variation in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG). These findings have led to the development of specialized genotyping platforms that can be used for fine-mapping and replication in other populations. We have combined the efficiency of EHR data and the economic advantages of the Illumina Metabochip, a custom designed SNP chip targeted to traits related to coronary artery disease, myocardial infarction, and type 2 diabetes, to conduct an array-wide analysis of lipid traits in a population with extreme obesity. Our analyses identified associations with 12 of 21 previously identified lipid-associated SNPs with effect sizes similar to prior results. Association analysis using several approaches to account for lipid-lowering medication use resulted in fewer and less strongly associated SNPs. The availability of phenotype data from the EHR and the economic efficiency of the specialized Metabochip can be exploited to conduct multi-faceted genetic association analyses. PMID:25147553

Portal thrombosis: dynamic CT features and course  

SciTech Connect

Portal thrombosis was diagnosed on computed tomography (CT) in 10 patients and confirmed by sonography. CT demonstrated decreased density of the portal vessels in 9 patients with peripheral arterial concentration of contrast material surrounding the intraluminal thrombus. The involved vessels were generally enlarged. Three patients had follow-up scans, which revealed a cavernoma in 2 and complete patency of the portal vein and its branches following anticoagulant therapy in 1. In the latter patient, localized abnormal intrahepatic blood flow suggested infarction of portal origin as the result of clot migration.

Regional Ocean Data Portal: Transforming Information to Knowledge  

NASA Astrophysics Data System (ADS)

The mission of the Gulf of Mexico Coastal Ocean Observing System’s (GCOOS) regional data portal is 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. Initially, the portal focused on aggregating relatively homogeneous oceanographic and marine meteorological data from the principal Gulf of Mexico data providers. Obtaining community agreements from the data providers on data formats, vocabularies, and levels of service was relatively easy because the technical barriers to participation were low and we were able to provide financial support to them to make small additions or changes to their local data systems. Over time, the portal requirements became more complex as new parameters, new providers and heterogeneous data streams were added and the spatial domain increased to include beaches and adjacent wetlands. This began to strain our resources and take us outside our science domains of expertise. During the same period, the Gulf of Mexico Alliance (GOMA), a new environmental quality initiative involving the five Gulf states and Mexico with similar goals and directives as those of our sponsor, gained momentum and demanded both our attention and participation. GOMA is working, mostly among themselves, to discover or establish community standards for various types of data sets - e.g. water quality and nutrients. In addition to aggregation, the portal is also tasked with producing products from the collected information streams. Arriving at a prioritized list of desired products has been a major part of the business conducted by the GCOOS Regional Association (RA). Numerous stakeholder (e.g. emergency responders, oil and gas producers, recreational boaters, etc.) workshops were held to elicit user needs and requirements for observing system products for each group. The GCOOS-RA’s Products and Services Committee and Education and Outreach Council have gone through similar activities aimed at determining what products various users groups want. We have been sensitive to the private sector when deciding which products to produce. While science users want numbers, users of all types mainly want maps. We have tried to develop flexible capabilities within the portal that helps users to create their own fused products, ad hoc, for a variety of output devices, from desktop screens to the smart phones. We will discuss how our data management system has evolved within the backdrop of rapidly changing technologies and diverse community requirements.

Leptogenesis and the Higgs Portal  

E-print Network

We study the impact on leptogenesis of Higgs portal couplings to a new scalar singlet. These couplings open up additional $CP$-violating decay channels for the higher mass singlet neutrinos $N_2$ and $N_3$. We analyze the simplest case of two-level $N_1-N_2$ leptogenesis, including significant mass hierarchies, in which the $CP$ asymmetry is generated in part by singlet-mediated decays of $N_2$. For these models, provided the lightest singlet neutrino $N_1$ is sufficiently weakly coupled to avoid excessive washout, its mass scale is not directly constrained by the Davidson-Ibarra bound.

The Portal to the Universe an IYA2009 Cornerstone Project  

NASA Astrophysics Data System (ADS)

The science of astronomy is extremely fast moving, and delivers new results on a daily basis, often in the form of spectacular news, images of forms and shapes not seen anywhere else, enhanced by illustrations and animations. Public astronomy communication has to develop apace with the other players in the mass market for electronic information such as the gaming and entertainment industries. The problem today is not so much the availability of excellent astronomy multimedia resources for use in education, outreach and the like, but rather finding and accessing these materials. The Portal to the Universe (TPTTU) seeks to fix this problem. The Portal to the Universe (TPTTU) is an IYA2009 Cornerstone project that will feature a comprehensive directory of observatories, facilities, astronomical societies, amateur astronomy societies, space artists, science communication universities, as well as news-, image-, event- and video- aggregators and Web 2.0 collaborative tools for astronomy multimedia community interaction. The Portal will enable innovative access to, and vastly multiply the use of, astronomy multimedia resources - including news, images, videos, events, podcasts, vodcasts etc. as a selective aggregator with a non-painful editorial mechanism in place. This talk will discuss the plans for the TPTTU content as well as the technology and editorial choices behind the scenes.

Las Cumbres Observatory Global Telescope (LCOGT) is building and deploying a world-wide network of optical telescopes dedicated to time-domain astronomy. During 2012-2013, we successfully deployed and commissioned nine new 1m telescopes at McDonald Observatory (Texas), CTIO (Chile), SAAO (South Africa) and Siding Spring Observatory (Australia). New, improved cameras and additional telescopes will be deployed during 2014. To enable the diverse LCOGT user community of scientific and educational users to request observations on the LCOGT Network and to see their progress and get access to their data, we have developed an Observation Portal system. This Observation Portal integrates proposal submission and observation requests with seamless access to the data products from the data pipelines in near-realtime and long-term products from the Science Archive. We describe the LCOGT Observation Portal and the data pipeline, currently in operation, which makes use of the ORAC-DR automated recipe-based data reduction pipeline and illustrate some of the new data products. We also present the LCOGT Science Archive, which is being developed in partnership with the Infrared Processing and Analysis Center (IPAC) and show some of the new features the Science Archive provides.

Liver Transplantation for Portal Cavernoma Cholangiopathy  

PubMed Central

Portal cavernoma cholangiopathy (PCC) is a difficult clinical problem, where the portal cavernoma is both the cause of biliary obstruction and the obstacle to its safe surgical treatment. The available endoscopic and surgical treatment is successful in majority and further intervention is seldom required since the native liver is normal. PCC is not an accepted indication for liver transplantation as only a small proportion of patients will fail both endoscopic and surgical treatment and progressive liver failure is rarely seen. Secondary biliary cirrhosis as a result of long standing biliary obstruction is an accepted indication however establishing a portal inflow in these patients is often difficult and challenging. The deceased donor liver transplantation would always be preferable over living donor liver transplantation as PCC is usually a non-emergency transplant and the graft can have portal blood inflow through a conduit to even a small segment of patent portal venous system or even to a cavernoma vessel.

Araport: the Arabidopsis information portal.  

PubMed

The Arabidopsis Information Portal (https://www.araport.org) is a new online resource for plant biology research. It houses the Arabidopsis thaliana genome sequence and associated annotation. It was conceived as a framework that allows the research community to develop and release 'modules' that integrate, analyze and visualize Arabidopsis data that may reside at remote sites. The current implementation provides an indexed database of core genomic information. These data are made available through feature-rich web applications that provide search, data mining, and genome browser functionality, and also by bulk download and web services. Araport uses software from the InterMine and JBrowse projects to expose curated data from TAIR, GO, BAR, EBI, UniProt, PubMed and EPIC CoGe. The site also hosts 'science apps,' developed as prototypes for community modules that use dynamic web pages to present data obtained on-demand from third-party servers via RESTful web services. Designed for sustainability, the Arabidopsis Information Portal strategy exploits existing scientific computing infrastructure, adopts a practical mixture of data integration technologies and encourages collaborative enhancement of the resource by its user community.

Background: With the Ebola epidemic raging out of control in West Africa, there has been a flurry of research into the Ebola virus, resulting in the generation of much genomic data. Methods: In response to the clear need for tools that integrate multiple strands of research around molecular sequences, we have created the University of California Santa Cruz (UCSC) Ebola Genome Browser, an adaptation of our popular UCSC Genome Browser web tool, which can be used to view the Ebola virus genome sequence from GenBank and nearly 30 annotation tracks generated by mapping external data to the reference sequence. Significant annotations include a multiple alignment comprising 102 Ebola genomes from the current outbreak, 56 from previous outbreaks, and 2 Marburg genomes as an outgroup; a gene track curated by NCBI; protein annotations curated by UniProt and antibody-binding epitopes curated by IEDB. We have extended the Genome Browser’s multiple alignment color-coding scheme to distinguish mutations resulting from non-synonymous coding changes, synonymous changes, or changes in untranslated regions. Discussion: Our Ebola Genome portal at http://genome.ucsc.edu/ebolaPortal/ links to the Ebola virus Genome Browser and an aggregate of useful information, including a collection of Ebola antibodies we are curating.

Retrospective checking of compliance with practice guidelines for acute stroke care: a novel experiment using openEHR’s Guideline Definition Language  

PubMed Central

Background Providing scalable clinical decision support (CDS) across institutions that use different electronic health record (EHR) systems has been a challenge for medical informatics researchers. The lack of commonly shared EHR models and terminology bindings has been recognised as a major barrier to sharing CDS content among different organisations. The openEHR Guideline Definition Language (GDL) expresses CDS content based on openEHR archetypes and can support any clinical terminologies or natural languages. Our aim was to explore in an experimental setting the practicability of GDL and its underlying archetype formalism. A further aim was to report on the artefacts produced by this new technological approach in this particular experiment. We modelled and automatically executed compliance checking rules from clinical practice guidelines for acute stroke care. Methods We extracted rules from the European clinical practice guidelines as well as from treatment contraindications for acute stroke care and represented them using GDL. Then we executed the rules retrospectively on 49 mock patient cases to check the cases’ compliance with the guidelines, and manually validated the execution results. We used openEHR archetypes, GDL rules, the openEHR reference information model, reference terminologies and the Data Archetype Definition Language. We utilised the open-sourced GDL Editor for authoring GDL rules, the international archetype repository for reusing archetypes, the open-sourced Ocean Archetype Editor for authoring or modifying archetypes and the CDS Workbench for executing GDL rules on patient data. Results We successfully represented clinical rules about 14 out of 19 contraindications for thrombolysis and other aspects of acute stroke care with 80 GDL rules. These rules are based on 14 reused international archetypes (one of which was modified), 2 newly created archetypes and 51 terminology bindings (to three terminologies). Our manual compliance checks for 49 mock patients were a complete match versus the automated compliance results. Conclusions Shareable guideline knowledge for use in automated retrospective checking of guideline compliance may be achievable using GDL. Whether the same GDL rules can be used for at-the-point-of-care CDS remains unknown. PMID:24886468

BSD Portals for LINUX 2.0  

NASA Technical Reports Server (NTRS)

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.

Freeze-in through portals  

NASA Astrophysics Data System (ADS)

The popular freeze-out paradigm for Dark Matter (DM) production, relies on DM-baryon couplings of the order of the weak interactions. However, different search strategies for DM have failed to provide a conclusive evidence of such (non-gravitational) interactions, while greatly reducing the parameter space of many representative models. This motivates the study of alternative mechanisms for DM genesis. In the freeze-in framework, the DM is slowly populated from the thermal bath while never reaching equilibrium. In this work, we analyse in detail the possibility of producing a frozen-in DM via a mediator particle which acts as a portal. We give analytical estimates of different freeze-in regimes and support them with full numerical analyses, taking into account the proper distribution functions of bath particles. Finally, we constrain the parameter space of generic models by requiring agreement with DM relic abundance observations.

Percutaneous Portal Vein Access and Transhepatic Tract Hemostasis  

PubMed Central

Percutaneous portal vein interventions require minimally invasive access to the portal venous system. Common approaches to the portal vein include transjugular hepatic vein to portal vein access and direct transhepatic portal vein access. A major concern of the transhepatic route is the risk of postprocedural bleeding, which is increased when patients are anticoagulated or receiving pharmaceutical thrombolytic therapy. Thus percutaneous portal vein access and subsequent closure are important technical parts of percutaneous portal vein procedures. At present, various techniques have been used for either portal access or subsequent transhepatic tract closure and hemostasis. Regardless of the method used, meticulous technique is required to achieve the overall safety and effectiveness of portal venous procedures. This article reviews the various techniques of percutaneous transhepatic portal vein access and the various closure and hemostatic methods used to reduce the risk of postprocedural bleeding.

The impact of numeracy ability and technology skills on older adults' performance of health management tasks using a patient portal.  

PubMed

Patient portals, which allow patients to access their health record via the Internet, are becoming increasingly widespread and are expected to be used by diverse consumer populations. In addition to technology skills, numeracy skills are also likely to be critical to performing health management tasks, as much of the data contained in the portal are numeric. This study examined how factors such as Internet experience, numeracy, and education impacted the performance of common tasks using a simulated patient portal among a sample of older adults. In addition, information was gathered on the ability of older adults to estimate their numeracy skills. Results indicated that numeracy and Internet experience had a significant impact on their ability to perform the tasks and that older adults tended to overestimate their numeracy skills. Results from this study can help to identify interventions that may enhance the usability of patient portals for older adults. PMID:24781964

[Emphysematous gastritis with concomitant portal venous air].  

PubMed

Emphysematous gastritis is a rare form of gastritis caused by infection of the stomach wall by gas forming bacteria. It is a very rare condition that carries a high mortality rate. Portal venous gas shadow represents elevation of intestinal luminal pressure which manifests as emphysematous gastritis or gastric emphysema. Literature reviews show that the mortality rate is especially high when portal venous gas shadow is present on CT scan. Until recently, the treatment of emphysematous gastritis has been immediate surgical intervention. However, there is a recent trend of avoiding surgery because of the frequent occurrence of post-operative complications such as anastomosis leakage. In addition, aggressive surgical treatment has failed to show significant improvement in prognosis. Recently, the authors experienced a case of emphysematous gastritis accompanied by portal venous gas which was treated successfully by conservative treatment without immediate surgical intervention. Herein, we present a case of emphysematous gastritis with concomitant portal venous air along with literature review. PMID:25716715

Concepts for a standard based cross-organisational information security management system in the context of a nationwide EHR.  

PubMed

Working with health related data necessitates appropriate levels of security and privacy. Information security, meaning ensuring confidentiality, integrity, and availability, is more organizational, than technical in nature. It includes many organizational and management measures, is based on well-defined security roles, processes, and documents, and needs permanent adaption of security policies, continuously monitoring, and measures assessment. This big challenge for any organization leads to implementation of an information security management system (ISMS). In the context of establishing a regional or national electronic health record for integrated care (ICEHR), the situation is worse. Changing the medical information exchange from on-demand peer-to-peer connections to health information networks requires all organizations participating in the EHR system to have consistent security levels and to follow the same security guidelines and rules. Also, the implementation must be monitored and audited, establishing cross-organizational information security management systems (ISMS) based on international standards. This paper evaluates requirements and defines basic concepts for an ISO 27000 series-based cross-organizational ISMS in the healthcare domain and especially for the implementation of the nationwide electronic health record in Austria (ELGA).

Nitroglycerine effects on portal vein mechanics and oxidative stress in portal hypertension  

PubMed Central

AIM: ?o examine the effects of nitroglycerine on portal vein haemodynamics and oxidative stress in patients with portal hypertension. METHODS: Thirty healthy controls and 39 patients with clinically verified portal hypertension and increased vascular resistance participated in the study. Liver diameters, portal diameters and portal flow velocities were recorded using color flow imaging/pulsed Doppler detection. Cross-section area, portal flow and index of vascular resistance were calculated. In collected blood samples, superoxide anion radical (O2-), hydrogen peroxide (H2O2), index of lipid peroxidation (measured as TBARS) and nitric oxide (NO) as a marker of endothelial response (measured as nitrite-NO2-) were determined. Time-dependent analysis was performed at basal state and in 10th and 15th min after nitroglycerine (sublingual 0.5 mg) administration. RESULTS: Oxidative stress parameters changed significantly during the study. H2O2 decreased at the end of study, probably via O2- mediated disassembling in Haber Weiss and Fenton reaction; O2- increased significantly probably due to increased diameter and tension and decreased shear rate level. Consequently O2- and H2O2 degradation products, like hydroxyl radical, initiated lipid peroxidation. Increased blood flow was to some extent lower in patients than in controls due to double paradoxes, flow velocity decreased, shear rate decreased significantly indicating non Newtonian characteristics of portal blood flow. CONCLUSION: This pilot study could be a starting point for further investigation and possible implementation of some antioxidants in the treatment of portal hypertension. PMID:22294839

The GB/3D Type Fossils Online Web Portal  

NASA Astrophysics Data System (ADS)

Fossils are the remains of once-living organisms that existed and played out their lives in 3-dimensional environments. The information content provided by a 3d representation of a fossil is much greater than that provided by a traditional photograph, and can grab the attention and imagination of the younger and older general public alike. The British Geological Survey has been leading a consortium of UK natural history museums including the Oxford University Museum of Natural History, the Sedgwick Museum Cambridge, the National Museum of Wales Cardiff, and a number of smaller regional British museums to construct a web portal giving access to metadata, high resolution images and interactive 3d models of type fossils from the UK. The web portal at www.3d-fossils.ac.uk was officially launched in August 2013. It can be used to discover metadata describing the provenance, taxonomy, and stratigraphy of the specimens. Zoom-able high resolution digital photographs are available, including for many specimens ';anaglyph' stereo images that can be viewed in 3d using red-cyan stereo spectacles. For many of the specimens interactive 3d models were generated by scanning with portable ';NextEngine 3D HD' 3d scanners. These models can be downloaded in zipped .OBJ and .PLY format from the web portal, or may be viewed and manipulated directly in certain web browsers. The images and scans may be freely downloaded subject to a Creative Commons Attribution ShareAlike Non-Commercial license. There is a simple application programming interface (API) allowing metadata to be downloaded, with links to the images and models, in a standardised format for use in data mash-ups and third party applications. The web portal also hosts ';open educational resources' explaining the process of fossilization and the importance of type specimens in taxonomy, as well as providing introductions to the most important fossil groups. We have experimented with using a 3d printer to create replicas of the fossils which can be used in education and public outreach. The audience for the web portal includes both professional paleontologists and the general public. The professional paleontologist can use the portal to discover the whereabouts of the type material for a taxon they are studying, and can use the pictures and 3d models to assess the completeness and preservation quality of the material. This may reduce or negate the need to send specimens (which are often fragile and always irreplaceable) to researchers through the post, or for researchers to make possibly long, expensive and environmentally damaging journeys to visit far-off collections. We hope that the pictures and 3d models will help to stimulate public interest in paleontology and natural history. The ability to digitally image and scan specimens in 3d enables institutions to have an archive record in case specimens are lost or destroyed by accident or warfare. Recent events in Cairo and Baghdad remind us that museum collections are vulnerable to civil and military strife.

A new ICPP portal monitor  

NASA Astrophysics Data System (ADS)

Low levels of beta and/or gamma contamination as well as gram quantities of special nuclear materials can be detected by a portal-mounted monitor even though the monitor is located in the presence of varying background levels of radiation. The detector consists of 14 area-wide gas proportional detectors, an occupancy monitor, an electronic system for signal and alarm logic, and support hardware. Each of the 14-15.3 and 35.6 cm propane purged detectors has a two to five mg/sq cm mylar cover and each detector has a total sensitive area of 450 sq cm. Six separate signal alarm and logic channels detect the presence of radioactivity and indicate whether the radiation is coming from the head, top right body, top left body, lower right body, lower left body, or the feet area, making it easier to locate the source and minimize personnel delay. The swinging door design of the monitor is such that anyone passing through must come into close proximity of the detectors and is slowed enough to allow for a meaningful scan without causing inordinate delays.

The ENSEMBLES Statistical Downscaling Portal  

NASA Astrophysics Data System (ADS)

The demand for high-resolution seasonal and ACC predictions is continuously increasing due to the multiple end-user applications in a variety of sectors (hydrology, agronomy, energy, etc.) which require regional meteorological inputs. To fill the gap between the coarse-resolution grids used by global weather models and the regional needs of applications, a number of statistical downscaling techniques have been proposed. Statistical downscaling is a complex multi-disciplinary problem which requires a cascade of different scientific tools to access and process different sources of data, from GCM outputs to local observations and to run complex statistical algorithms. Thus, an end-to-end approach is needed in order to link the outputs of the ensemble prediction systems to a range of impact applications. To accomplish this task in an interactive and user-friendly form, a Web portal has been developed within the European ENSEMBLES project, integrating the necessary tools and providing the appropriate technology for distributed data access and computing. In this form, users can obtain their downscaled data testing and validating different statistical methods (from the categories weather typing, regression or weather generators) in a transparent form, not worrying about the details of the downscaling techniques and the data formats and access.

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.

The MISTRALS programme data portal  

NASA Astrophysics Data System (ADS)

Mediterranean Integrated STudies at Regional And Local Scales (MISTRALS) is a decennial programme for systematic observations and research dedicated to the understanding of the Mediterranean Basin environmental process and its evolution under the planet global change. It is composed of eight multidisciplinary projects that cover all the components of the Earth system (atmosphere, ocean, continental surfaces, lithosphere...) and their interactions, many disciplines (physics, chemistry, marine biogeochemistry, biology, geology, sociology...) and different time scales. For example Hydrological cycle in the Mediterranean eXperiment (HyMeX) aims at improving the predictability of rainfall extreme events, and assessing the social and economic vulnerability to extreme events and adaptation capacity, and Paleo Mediterranean Experiment (PaleoMeX) is dedicated to the study of the interactions between climate, societies and civilizations of the Mediterranean world during the last 10000 years. Many long term monitoring research networks are associated with MISTRALS, like Mediterranean Ocean Observing System on Environment (MOOSE), Centre d'Observation Régional pour la Surveillance du Climat et de l'environnement Atmosphérique et océanographique en Méditerranée occidentale (CORSICA) and the environmental observations from Mediterranean Eurocentre for Underwater Sciences and Technologies (MEUST-SE). Therefore, the data generated or used by the different MISTRALS projects are very heterogeneous. They include in situ observations, satellite products, model outputs, qualitative field surveys... Some datasets are automatically produced by operational networks, and others come from research instruments and analysis procedures. They correspond to different time scales (historical time series, observatories, campaigns...) and are managed by different data centres. They originate from many scientific communities, with varied data sharing cultures, specific expectations, and using different file formats and data processing tools. The MISTRALS data portal - http://mistrals.sedoo.fr/ - has been designed and developed as a unified tool to share scientific data in spite of many sources of heterogeneity, and to foster collaboration between research communities. The metadata (data description) are standardized and comply with international standards (ISO 19115-19139; INSPIRE European Directive; Global Change Master Directory Thesaurus). A search tool allows to browse the catalogue by keyword or by multicriteria selection (location, period, physical property...) and to access data. Data sets managed by different data centres (ICARE, IPSL, SEDOO, CORIOLIS) are available through interoperability protocols (OPeNDAP, xml requests...) or archive synchronisation. At present the MISTRALS data portal allows to access more than 400 datasets and counts more than 500 registered users. The number of available datasets is increasing daily, due to the provision of campaign datasets (2012, 2013) by several projects. Every in situ data set is available in the native format, but the favorite data sets have been homogenized (property names, units, quality flags...) and inserted in a relational database, in order to enable more accurate data selection, and download of different datasets in a shared format. Every scientist is invited to make use of the different MISTRALS tools and data. Do not hesitate to browse the catalogue and fill the online registration form. Feel free to contact mistrals-contact@sedoo.fr for any question.

The Double-Dark Portal  

E-print Network

In most models of the dark sector, dark matter is charged under some new symmetry to make it stable. We explore the possibility that not just dark matter, but also the force carrier connecting it to the visible sector is charged under this symmetry. This dark mediator then acts as a Double-Dark Portal. We realize this setup in the \\emph{dark mediator Dark matter} model (dmDM), featuring a fermionic DM candidate $\\chi$ with Yukawa couplings to light scalars $\\phi_i$. The scalars couple to SM quarks via the operator $\\bar q q \\phi_i^* \\phi_j/\\Lambda_{ij}$. This can lead to large direct detection signals via the $2\\rightarrow3$ process $\\chi N \\rightarrow \\chi N \\phi$ if one of the scalars has mass $ \\lesssim 10$ keV. For dark matter Yukawa couplings $y_\\chi \\sim 10^{-3} - 10^{-2}$, dmDM features a thermal relic dark matter candidate while also implementing the SIDM scenario for ameliorating inconsistencies between dwarf galaxy simulations and observations. We undertake the first systematic survey of constraints on light scalars coupled to the SM via the above operator. The strongest constraints are derived from a detailed examination of the light mediator's effects on stellar astrophysics. LHC experiments and cosmological considerations also yield important bounds. Observations of neutron star cooling exclude the minimal model with one dark mediator, but a scenario with two dark mediators remains viable and can give strong direct detection signals. We explore the direct detection consequences of this scenario and find that a heavy $\\mathcal{O}(100)$ GeV dmDM candidate fakes different $\\mathcal{O}(10)$ GeV WIMPs at different experiments. Large regions of dmDM parameter space are accessible above the irreducible neutrino background.

Investigating the efficacy of subharmonic aided pressure estimation for portal vein pressures and portal hypertension monitoring  

PubMed Central

The efficacy of using subharmonic emissions from Sonazoid microbubbles (GE Healthcare, Oslo, Norway) to track portal vein pressures and pressure changes was investigated in 14 canines using either slow- or high-flow models of portal hypertension (PH). A modified Logiq 9 scanner (GE Healthcare, Milwaukee, WI) operating in subharmonic mode (ftransmit:2.5MHz, freceive:1.25MHz) was used to collect RF data at 10-40% incident acoustic power levels with 2-4 transmit cycles (in triplicate), before and after inducing PH. A pressure catheter (Millar Instruments, Inc., Houston, TX) provided reference portal vein pressures. At optimum insonification, subharmonic signal amplitude changes correlated with portal vein pressure changes; r ranged from -0.82 to -0.94 and from -0.70 to -0.73 for PH models considered separately or together, respectively. The subharmonic signal amplitudes correlated with absolute portal vein pressures (r: -0.71 to -0.79). Statistically significant differences between subharmonic amplitudes, before and after inducing PH, were noted (p?0.01). Portal vein pressures estimated using SHAPE did not reveal significant differences (p>0.05) with respect to the pressures obtained using the Millar pressure catheter. Subharmonic aided pressure estimation may be useful clinically for portal vein pressure monitoring. PMID:22920550

Effect of Fluid Shear Stress on Portal Vein Remodeling in a Rat Model of Portal Hypertension  

PubMed Central

Aims. To explore the effects and mechanisms of fluid shear stress on portal vein remodeling in a rat model of portal hypertension. Methods. Subcutaneous injections of CCl4 were given to establish a rat model of liver cirrhosis and portal hypertension. Biomechanical technology was adopted to determine the dynamic changes of haemodynamic indices and fluid shear stress. Nitric oxide (NO), synthase (NOS), and endothelin-1 (ET-1) of the portal vein blood were measured. Changes in geometric structure and ultrastructure of the portal vein were observed using optical and electron microscopy. Results. After the CC14 injections, rat haemodynamics were notably altered. From week 4 onwards, PVP, PVF, and PVR gradually and significantly increased (P < 0.05 versus baseline). The fluid shear stress declined from week 4 onwards (P < 0.01 versus control group). NO, NOS, and ET-1 increased after repeated CCI4 injections. Hematoxylin and eosin staining showed thickened portal vein walls, with increased inside and outside diameters. Electron microscopy revealed different degrees of endothelial cell degeneration, destruction of basement membrane integrity, proliferating, and hypertrophic smooth muscle cells. Conclusions. Fluid shear stress not only influenced the biomechanical environment of the portal vein but also participated in vascular remodeling.

Portal Cavernoma Cholangiopathy—Clinical Characteristics  

PubMed Central

Because of the presence of portal cavernoma, paracholedochal and pericholedochal varices, portal cavernoma cholangiopathy (PCC) has become an entity unique to patients with extrahepatic portal venous obstruction (EHPVO). Majority of patients with these abnormalities are asymptomatic and are incidentally detected to have the presence of biliary abnormalities on cholangiography. Minority of patients present with symptoms of chronic cholestasis with or without biliary pain or acute cholangitis related most often to the presence of biliary strictures or stones. Other than the age of the patient and duration of EHPVO, presence of gall stones and common bile duct stones are other risk factors for the causation of symptoms in patients with PCC. This review summarizes the clinical characteristics of asymptomatic and symptomatic patients with PCC giving details of the prevalence of symptoms, their risk factors and overall burden of symptomatic PCC.

Portal Hypertension and Ascites in Extramedullary Hematopoiesis  

PubMed Central

Myeloproliferative diseases (MPD) are clonal stem cell disorders which mainly include polycythemia vera (PV), essential thrombocythemia (ET), and idiopathic myelofibrosis (IMF). They are characterized by leucocytosis, thrombocytosis, erythrocytosis, splenomegaly, and bone marrow hypercellularity. This might also result in extramedullary hematopoiesis. Abdominal manifestation has been recognized as a feature of these disorders. Splenomegaly and hepatomegaly are fairly common as opposed to ascites which is rare. The MPDs mainly affect the hepatic circulatory systems. The common hepatic manifestations are Budd-Chiari syndrome (BCS), portal vein thrombosis (PVT), and nodular regenerative hyperplasia. A few other features seen in MPDs are caused by extramedullary hematopoiesis, increased hepatic blood flow, and secondary hemosiderosis from multiple blood transfusions. Portal hypertension is found in up to 7% of patients. We report a case of portal hypertension with ascites in a patient with extramedullary hematopoiesis treated with transjugular intrahepatic portocaval shunt (TIPS).

With a data archive of more than 1.5 petabytes and a key role as the NASA Distributed Active Archive Center (DAAC) for synthetic aperture radar (SAR) data, the Alaska Satellite Facility (ASF) has an imperative to develop effective Web data portals. As part of continuous enhancement and expansion of its website, ASF recently created two data portals for distribution of SAR data: one for the archiving and distribution of NASA's MEaSUREs Wetlands project and one for newly digitally processed data from NASA's 1978 Seasat satellite. These case studies informed ASF's development of the following set of best practices for developing Web data portals. 1) Maintain well-organized, quality data. This is fundamental. If data are poorly organized or contain errors, credibility is lost and the data will not be used. 2) Match data to likely data uses. 3) Identify audiences in as much detail as possible. ASF DAAC's Seasat and Wetlands portals target three groups of users: a) scientists already familiar with ASF DAAC's SAR archive and our data download tool, Vertex; b) scientists not familiar with SAR or ASF, but who can use the data for their research of oceans, sea ice, volcanoes, land deformation and other Earth sciences; c) audiences wishing to learn more about SAR and its use in Earth sciences. 4) Identify the heaviest data uses and the terms scientists search for online when trying to find data for those uses. 5) Create search engine optimized (SEO) Web content that corresponds to those searches. Because search engines do not yet search raw data, so Web data portals must include content that ties the data to its likely uses. 6) Create Web designs that best serves data users (user centered design), not for how the organization views itself or its data. Usability testing was conducted for the ASF DAAC Wetlands portal to improve the user experience. 7) Use SEO tips and techniques. The ASF DAAC Seasat portal used numerous SEO techniques, including social media, blogging technology, SEO rich content and more. As a result, it was on the first page of numerous related Google search results within 24 hours of the portal launch. 8) Build in-browser data analysis tools showing scientists how the data can be used in their research. The ASF DAAC Wetlands portal demonstrates that allowing the user to examine the data quickly and graphically online readily enables users to perceive the value of the data and how to use it. 9) Use responsive Web design (RWD) so content and tools can be accessed from a wide range of devices. Wetlands and Seasat can be accessed from smartphones, tablets and desktops. 10) Use Web frameworks to enable rapid building of new portals using consistent design patterns. Seasat and Wetlands both use Django and Twitter Bootstrap. 11) Use load-balanced servers if high demand for the data is anticipated. Using load-balanced servers for the Seasat and Wetlands portals allows ASF to simply add hardware as needed to support increased capacity. 12) Use open-source software when possible. Seasat and Wetlands portal development costs were reduced, and functionality was increased, with the use of open-source software. 13) Use third-party virtual servers (e.g. Amazon EC2 and S3 Services) where applicable. 14) Track visitors using analytic tools. 15) Continually improve design.

Application of the smart portal in transportation  

SciTech Connect

Under a program sponsored by the Department of Energy, the Oak Ridge complex is developed a ``Portal-of-the-Future``, or ``smart portal``. This is a security portal for vehicular traffic which is intended to quickly detect explosives, hidden passengers, etc. It uses several technologies, including microwaves, weigh-in-motion, digital image processing, and electroacoustic wavelet-based heartbeat detection. A novel component of particular interest is the Enclosed Space Detection System (ESDS), which detects the presence of persons hiding in a vehicle. The system operates by detecting the presence of a human ballistocardiographic signature. Each time the heart beats, it generates a small but measurable shock wave that propagates through the body. The wave, whose graph is called a ballistocardiogram, is the mechanical analog of the electrocardiogram, which is routinely used for medical diagnosis. The wave is, in turn, coupled to any surface or object with which the body is in contact. If the body is located in an enclosed space, this will result in a measurable deflection of the surface of the enclosure. Independent testing has shown ESDS to be highly reliable. The technologies used in the smart portal operate in real time and allow vehicles to be checked through the portal in much less time than would be required for human inspection. Although not originally developed for commercial transportation, the smart portal has the potential to solve several transportation problems. It could relieve congestion at international highway border crossings by reducing the time required to inspect each vehicle while increasing the level of security. It can reduce highway congestion at the entrance of secure facilities such as prisons. Also, it could provide security at intermodal transfer points, such as airport parking lots and car ferry terminals.

Collaboration Portals for NASA's Airborne Field Campaigns  

NASA Technical Reports Server (NTRS)

The University of Alabama in Huntsville (UAH), in collaboration with the Global Hydrology Resource Center, a NASA Earth Science Data Center, has provided information management for a number of NASA Airborne Field campaigns, both hurricane science investigations and satellite instrument validation. Effective field campaign management requires communication and coordination tools, including utilities for personnel to upload and share flight plans, weather forecasts, a variety of mission reports, preliminary science data, and personal photos. Beginning with the Genesis and Rapid Intensification Processes (GRIP) hurricane field campaign in 2010, we have provided these capabilities via a Drupal-based collaboration portal. This portal was reused and modified for the Midlatitude Continental Convective Clouds Experiment (MC3E), part of the Global Precipitation Measurement mission ground validation program. An end goal of these development efforts is the creation of a Drupal profile for field campaign management. This presentation will discuss experiences with Drupal in developing and using these collaboration portals. Topics will include Drupal modules used, advantages and disadvantages of working with Drupal in this context, and how the science teams used the portals in comparison with other communication and collaboration tools.

Portal hypertension in acute liver failure.  

PubMed Central

Twenty five patients with acute liver failure were measured for hepatic venous pressure gradient as an index of portal pressure during the course of a transjugular liver biopsy. Hepatic venous pressure gradient ranged from 4 to 24.5 mm Hg with a mean of 12.8 (5.3) mm Hg (normal values less than 5 mm Hg). All patients but one had increased portal pressure gradient. Portal hypertension correlated with the degree of architectural distortion of the liver, as suggested by a direct correlation between hepatic venous pressure gradient and the area of reticulin collapse, evaluated by means of a morphometric analysis on Sirius red stained liver slides (r = 0.43, p less than 0.05). Hepatic venous pressure gradient was significantly higher in patients with ascites (15.1 (5) mm Hg, n = 15) or renal failure (14.4 (5.3) mm Hg, n = 16) than in those without (9.3 (3.4) mm Hg and 10.1 (4) mm Hg, respectively; p less than 0.05). Portal hypertension was associated with systemic vasodilation and a hyperkinetic circulatory state, with decreased arterial pressure, and peripheral resistance and increased cardiac output.

Pathophysiology of Portal Hypertension and Its Clinical Links  

PubMed Central

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.

Portal hypertension as portrayed by marked hepatosplenomegaly: case report  

SciTech Connect

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.

Transjugular Intrahepatic Portosystemic Shunt for the Treatment of Portal Hypertension in Noncirrhotic Patients with Portal Cavernoma  

PubMed Central

Background. The purpose of this study was to evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) placement in the management of portal hypertension in noncirrhotic patients with portal cavernoma. Methods. We conducted a single institution retrospective analysis of 15 noncirrhotic patients with portal cavernoma treated with TIPS placement. 15 patients (4 women and 11 men) were evaluated via the technical success of TIPS placement, procedural complications, and follow-up shunt patency. Results. TIPS placement was technically successful in 11 out of 15 patients (73.3%). Procedure-related complications were limited to a single instance of hepatic encephalopathy in one patient. In patients with successful shunt placement, the portal pressure gradient decreased from 25.8 ± 5.7 to 9.5 ± 4.2?mmHg (P < 0.001). TIPS dysfunction occurred in two patients during a median follow-up time of 45.2 months. Revision was not performed in one patient due to inadequate inflow. The other patient died of massive gastrointestinal bleeding in a local hospital. The remaining nine patients maintained functioning shunts through their last evaluation. Conclusions. TIPS is a safe and effective therapeutic treatment for noncirrhotic patients with symptomatic portal hypertension secondary to portal cavernoma. PMID:24868203

Anatomy of the Portal Vein Bifurcation: Implication for Transjugular Intrahepatic Portal Systemic Shunts  

SciTech Connect

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.

Noninvasive Evaluation of Portal Hypertension: Emerging Tools and Techniques  

PubMed Central

Portal hypertension is the main cause of complications in patients with cirrhosis. However, evaluating the development and progression of portal hypertension represents a challenge for clinicians. There has been considerable focus on the potential role of noninvasive markers of portal hypertension that could be used to stratify patients with respect to the stage of portal hypertension and to monitor disease progression or treatment response in a longitudinal manner without having to undertake repeated invasive assessment. The pathogenesis of portal hypertension is increasingly understood and emerging knowledge of the vascular processes that underpin portal hypertension has paved the way for exploring novel biomarkers of vascular injury, angiogenesis, and endothelial dysfunction. In this paper we focus on the pathogenesis of portal hypertension and potential non-invasive biomarkers with particular emphasis on serum analytes. PMID:22720166

Portal vein arterialization technique for liver transplantation patients  

PubMed Central

Liver transplantations were performed on two patients with hepatic failure caused by liver cirrhosis. Hard obsolete thrombi and portal venous sclerosis were observed in the major portal veins of both patients. The arteria colica media of one recipient and the portal vein of the donor were anastomosed end-to-end. The hepatic artery of the first donor was anastomosed end-to end with the gastroduodenal artery of the first recipient; meanwhile, the portal vein of the second donor was simultaneously anastomosed end- to-end with the common hepatic artery of the second recipient. The blood flow of the portal vein, the perfusion of the donor liver and liver function were satisfactory after surgery. Portal vein arterialization might be an effective treatment for patients whose portal vein reconstruction was difficult. PMID:25232274

We describe a case of a ruptured hepatocellular carcinoma supplied by the portal vein that was successfully treated with portal vein embolization via a percutaneous transumbilical approach. A contrast material-enhanced computed tomographic (CT) scan showed the presence of a large hypervascular tumor on portal venous phase as well as right hepatic vein thrombosis and hemoperitoneum that prevented portal vein embolization by the use of the percutaneous and transjugular transhepatic approach. The use of percutaneous transumbilical portal vein embolization can be an alternative option in this situation.

Pediatric liver transplant portal vein anastomotic stenosis: Correlation between ultrasound and transhepatic portal venography.  

PubMed

The objective of this study was to determine which transabdominal ultrasound parameters correlate with portal vein stenosis (PVS) on percutaneous transhepatic portal venography in pediatric liver transplant patients. A retrospective review was performed of percutaneous transhepatic portal venograms performed between 2005 and 2013. The findings were compared to those from ultrasounds performed before venography and at the baseline. Patients were stratified on the basis of the presence of significant PVS (group 1, >50% stenosis; group 2, ?50% stenosis) on portal venography. Findings were compared to those for age-matched controls. Twenty portal venograms were performed for 12 pediatric patients. Thirteen of the 20 patients (65%) demonstrated significant PVS (>50%). The mean peak anastomotic velocity (PAV) was 253.6?±?96 cm/s in group 1, 169.7?±?48 cm/s in group 2, and 51.3?±?20 cm/s in the control group. PAV (r?=?0.672, P = 0.002) was the only ultrasound variable that correlated with the presence of significant PVS. A receiver operating characteristic curve was generated from PAV and PVS data (area under the curve?=?0.75, P?=?0.08). A threshold velocity of 180 cm/s led to a sensitivity of 83% and a specificity of 71% in predicting significant PVS on portal venography. At the baseline, the mean PAV was 155.8?±?90 cm/s for group 1 and 69.5?±?33 cm/s for group 2 (P?=?0.08); for control subjects, it was 78.9?±?53 cm/s (P?=?0.06). PAV is the only measured ultrasound parameter that correlates with significant PVS on portal venography in pediatric liver transplant patients. An elevated baseline PAV may increase the risk of developing PVS. Liver Transpl 21:547-553, 2015. © 2015 AASLD. PMID:25648978

Phase contrast portal imaging using synchrotron radiation  

SciTech Connect

Microbeam radiation therapy is an experimental form of radiation treatment with great potential to improve the treatment of many types of cancer. We applied a synchrotron radiation phase contrast technique to portal imaging to improve targeting accuracy for microbeam radiation therapy in experiments using small animals. An X-ray imaging detector was installed 6.0 m downstream from an object to produce a high-contrast edge enhancement effect in propagation-based phase contrast imaging. Images of a mouse head sample were obtained using therapeutic white synchrotron radiation with a mean beam energy of 130 keV. Compared to conventional portal images, remarkably clear images of bones surrounding the cerebrum were acquired in an air environment for positioning brain lesions with respect to the skull structure without confusion with overlapping surface structures.

Heavy Dark Matter Through the Higgs Portal  

E-print Network

Motivated by Higgs Portal and Hidden Valley models, heavy particle dark matter that communicates with the supersymmetric Standard Model via pure Higgs sector interactions is considered. We show that a thermal relic abundance consistent with the measured density of dark matter is possible for masses up to $\\sim 30\\tev$. For dark matter masses above $\\sim 1\\tev$, non-perturbative Sommerfeld corrections to the annihilation rate are large, and have the potential to greatly affect indirect detection signals. For large dark matter masses, the Higgs-dark-matter-sector couplings are large and we show how such models may be given a UV completion within the context of so-called "Fat-Higgs" models. Higgs Portal dark matter provides an example of an attractive alternative to conventional MSSM neutralino dark matter that may evade discovery at the LHC, while still being within the reach of current and upcoming indirect detection experiments.

Portal Vein Embolization: What Do We Know?  

SciTech Connect

Portal vein embolization (PVE) has been developed to increase the size of the future remnant liver (FRL) left in place after major hepatectomy, thus reducing the risk of postoperative liver insufficiency. PVE consist in embolizing preoperatively portal branches of the segments that will be resected. Indication is based on preoperative measurements of the FRL by computed tomography and its ratio with either the theoretical liver volume or by direct measurement of the functional liver volume. After PVE, the volume and function of the FRL increases in 3 to 6 weeks, permitting extensive resections in patients otherwise contraindicated for liver resection. The PVE technique is variable from one center to another; however n-butyl-cyano-acrylate provides an interesting compromise between hypertrophy rate and procedure risk.

Phase contrast portal imaging using synchrotron radiation  

NASA Astrophysics Data System (ADS)

Microbeam radiation therapy is an experimental form of radiation treatment with great potential to improve the treatment of many types of cancer. We applied a synchrotron radiation phase contrast technique to portal imaging to improve targeting accuracy for microbeam radiation therapy in experiments using small animals. An X-ray imaging detector was installed 6.0 m downstream from an object to produce a high-contrast edge enhancement effect in propagation-based phase contrast imaging. Images of a mouse head sample were obtained using therapeutic white synchrotron radiation with a mean beam energy of 130 keV. Compared to conventional portal images, remarkably clear images of bones surrounding the cerebrum were acquired in an air environment for positioning brain lesions with respect to the skull structure without confusion with overlapping surface structures.

Idiopathic Non Cirrhotic Portal Hypertension and Spleno-Portal Axis Abnormalities in Patients with Severe Primary Antibody Deficiencies  

PubMed Central

Background and Aim. Portal hypertension has been reported in association with acquired and primary immune deficiencies without a comprehensive description of associated spleno-portal axis abnormalities. Pathological mechanisms are poorly defined. Methods. Observational, single centre study with the aim of assessing the prevalence of spleno-portal axis abnormalities in an unselected cohort of 123 patients with primary antibody deficiencies and without known causes of liver diseases regularly followed up for a mean time of 18 ± 14 years. A cumulative period of 1867 patients-year was analysed. Clinical and immunological data, abdominal ultrasounds, CT scans, and endoscopy features were included in the analysis. Results. Twenty-five percent of patients with primary antibody deficiencies had signs of portal vein enlargement but only 4% of them had portal hypertension, with portal systemic collaterals. Liver biopsies showed liver sinusoids congestive dilatation, endothelization, and micronodularity fulfilling the criteria for noncirrhotic portal hypertension. Patients with portal vein enlargement had severe clinical and immunological phenotypes. Conclusions. In primary antibody deficient patients, infections, inflammations, splenomegaly, increased blood venous flow, and lymphocyte abnormalities contribute to establishment of liver damage possibly leading to noncirrhotic portal hypertension. Patients with primary antibody deficiency should be considered a good model to give insight into the pathological mechanisms underlying noncirrhotic portal hypertension. PMID:24741616

Inflammation and portal hypertension - the undiscovered country.  

PubMed

Portal hypertension has traditionally been viewed as a progressive process, involving ultrastructural changes including fibrosis, nodule formation, and vascular thrombosis, leading to increased intrahepatic resistance to flow. However, it is increasingly recognized that a significant component of this vascular resistance results from a dynamic process, regulated by complex interactions between the injured hepatocyte, the sinusoidal endothelial cell, the Kupffer cell and the hepatic stellate cell, which impact on sinusoidal calibre. Recent findings suggest these haemodynamic findings are most marked in patients with superimposed inflammation. The precise mechanisms for vascular dysfunction in cirrhosis with superimposed inflammation remain to be fully elucidated but several studies over the past decade have started to generate the hypothesis that inflammation may be a key mediator of the pathogenesis and severity of portal hypertension in this context. This review provides a comprehensive overview of the biological mechanisms for inflammation playing a key role in the severity of portal hypertension, and illustrates potential novel therapies that act by modifying these processes.

Photonic dark matter portal and quantum physics  

E-print Network

To identify the nature and properties of dark matter is one of the most serious open problems in modern physics. We study a model of dark matter in which the hidden sector interacts with ordinary matter (standard model particles) via photonic portal(hidden photonic portal). We search for the effects of this new interaction in quantum physics, therefore we study its effects on hydrogen atom because it is a simple and a well-studied quantum system so it can be considered as an outstanding test for dark matter signatures. Using the accuracy of the measurement of energy, we obtain an upper bound for the coupling constant of the model. We also calculate the contribution to the anomalous magnetic moment of muon due to the hidden photonic portal. At the moment there is a deviation between the standard model prediction for muon anomalous magnetic moment and its experimental value so the anomalous magnetic moment of muon can provide an important test of the standard model and the theories beyond it.

Surgical Management of Portal Cavernoma Cholangiopathy  

PubMed Central

The majority of patients with portal cavernoma cholangiopathy (PCC) are asymptomatic, however some (5–38%) present with obstructive jaundice, cholangitis, or even biliary pain due to bile duct stones which form as a result of stasis. Most patients with extrahepatic portal venous obstruction (EHPVO) present with variceal bleeding and hypersplenism and these are the usual indications for surgery. Those who present with PCC may also need decompression of their portosystemic system to reverse the biliary obstruction. It is important to realize that though endoscopic drainage has been proposed as a non-surgical approach to the management of PCC it is successful in only certain specific situations like those with bile duct calculi, cholangitis, etc. A small proportion of such patients will continue to have biliary obstruction and these patients are thought to have a mechanical ischemic stricture. These patients will require a second stage procedure in the form of a bilioenteric bypass to reverse the symptoms related to PCC. In the absence of a shuntable vein splenectomy and devascularization may resolve the PCC in a subset of patients by decreasing the portal pressure. PMID:25755599

[Portal hypertension. Evidence-based guide].  

PubMed

Treatment of portal hypertension has evolved widely during the last decades. Advances in physiopathology have allowed better application of therapeutic options and also have permitted to know the natural history of varices and variceal bleeding, predicting which patients have a higher risk of bleeding. It also permits probability of designing patient treatment. According to liver function and subadjacent liver disease, it is possible to offer different alternatives within the three possible scenarios (primary prophylaxis, acute bleeding episode, and secondary prophylaxis). For primary prophylaxis, pharmacotherapy offers the best choice. Endoscopic banding is also growing in these scenarios and probably will be accepted in the near future. For the acute bleeding episode, endoscopic therapy (sclerosis and/or bands) and/or pharmacologic therapy (octreotide, terlipresin) represent best choice, considering TIPS as a rescue option. Surgery is not used routinely in this scenario in most centers. For secondary prophylaxis, pharmaco- and endoscopic therapy are first-line treatments, while TIPS and surgery as second-line treatments. TIPS is mainly used in patients on a waiting list for liver transplantation. Surgery offers good results for low-risk patients, with good liver function and with portal blood-flow preserving procedures (selective shunts, extensive devascularizations). Liver transplantation is recommended for patients with poor liver function because together with portal hypertension, it treats subadjacent liver disease. PMID:15757160

Explosives detection portal for high-volume personnel screening  

NASA Astrophysics Data System (ADS)

We discuss a trace explosive detection portal for high-volume personnel screening, which has been developed recently at Sandia National Laboratories (SNL), using funding provided by the Federal Aviation Administration (FAA) and the Department of Energy (DOE) Office of Safeguards and Security (OSS). This portal screens individuals for explosives using noninvasive means to collect explosive residue in the forms of vapor and particulate contamination. The portal combines a commercially available ion mobility spectrometer (IMS) with a preconcentrator developed at SNL to perform detection of explosives. The prototype portal has undergone one series of tests at the Albuquerque International Airport, and we are now proceeding to develop an improved, second-generation portal, and to find a company to market the portal.

Portal and systemic bacteraemia and endotoxaemia in liver disease.  

PubMed Central

Using a percutaneous transhepatic technique, blood was obtained from the portal veins of 30 patients with various hepatic disorders and examined for the presence of bacteria and endotoxin. Simultaneous samples also were drawn from hepatic and peripheral veins. In three cases, portal vein cultures grew diphtheroids, which were of doubtful significance, while all hepatic and peripheral cultures were sterile. Endotoxin was detected in seven portal vein samples; in none of these patients were the hepatic or peripheral blood samples positive. In three cases, only peripheral blood samples were positive for endotoxin. It was concluded that portal bacteraemia occurs as infrequently in patients with liver disease as in those without. Portal endotoxaemia was detected in patients with all degrees of liver disease but, even in patients with moderately severe portal hypertension, the liver may remain an effective filter of endotoxin.

Consortium for Oral Health-Related Informatics: Improving Dental Research, Education, and Treatment  

PubMed Central

Advances in informatics, particularly the implementation of electronic health records (EHR), in dentistry have facilitated the exchange of information. The majority of dental schools in North America use the same EHR system, providing an unprecedented opportunity to integrate these data into a repository that can be used for oral health education and research. In 2007, fourteen dental schools formed the Consortium for Oral Health-Related Informatics (COHRI). Since its inception, COHRI has established structural and operational processes, governance and bylaws, and a number of work groups organized in two divisions: one focused on research (data standardization, integration, and analysis), and one focused on education (performance evaluations, virtual standardized patients, and objective structured clinical examinations). To date, COHRI (which now includes twenty dental schools) has been successful in developing a data repository, pilot-testing data integration, and sharing EHR enhancements among the group. This consortium has collaborated on standardizing medical and dental histories, developing diagnostic terminology, and promoting the utilization of informatics in dental education. The consortium is in the process of assembling the largest oral health database ever created. This will be an invaluable resource for research and provide a foundation for evidence-based dentistry for years to come. PMID:20930236

ACTRIS Data Centre: An atmospheric data portal  

NASA Astrophysics Data System (ADS)

ACTRIS (Aerosols, Clouds, and Trace gases Research InfraStructure Network) is a European Project aiming at integrating European ground-based stations equipped with advanced instrumentation for studying aerosols, clouds, and short-lived gas-phase species. The ACTRIS activities result in improved atmospheric measurements data made at more than 60 European sites, from numerous instruments and includes variables measured by ground based in situ and remote sensing technologies. Core variables are in situ aerosol optical, physical and chemical properties, short-lived trace gases (volatile organic carbon and nitrogen oxides), aerosol scattering and extinction profiles, and cloud properties. The ACTRIS data centre (ACTRIS DC) is giving free and open access to all data resulting from the activities of the infrastructure network, complemented with data from other relevant networks and data bases. The overall goal is to facilitate scientists and other user groups access to atmospheric observational data, and to provide mature products for analysis and interpretation of atmospheric composition change. The ACTRIS DC aims at substantially increasing the number of high-quality data by providing long-term observational data relevant to climate and air quality research produced with standardized or comparable procedures throughout the network. The backbone of the ACTRIS DC is the three core data bases: - EARLINET Data Base hosting aerosol lidar data from more than 30 European sites - EBAS hosting ground based atmospheric in situ data from more than 1000 sites globally - Cloudnet hosting remote sensing cloud data and products from 5 European sites Furthermore, a joint portal is developed combining information from various data sources to gain new information not presently available from standalone databases or networks. The data centre will provide tools and services to facilitate the use of measurements for broad user communities. Higher level and integrated products will be developed stage-by-stage during the project, and user requirements, interactions and feedbacks are essential. The first version of ACTRIS DC is a web portal that allows users to search for atmospheric composition data from a multitude of data archives through a single user interface. Examples of data bases and frameworks included are EMEP, the GAW- world data centres, EARLINET, NDACC, CARIBIC-GEOmon, HTAP, AMAP amongst others. Currently the portal provides an overview of more than 800 000 data sets from more than 20 data bases/frameworks globally. For some of the databases included in the portal, the interface furthermore allows you to download data directly through the portal. A map functionality is implemented facilitating the identification of data and making it possible to search for collocation of observations, variables and sites both in time and space. The data portal can serve as "one-stop-shop" of atmospheric high-quality data, and the portal will also offer a direct interface towards external users like the MACC II project and GMES in-situ. The data dissemination will take into account the principles outlined in SEIS, INSPIRE, WIS and GEOSS.

Open source portal to distributed image repositories  

NASA Astrophysics Data System (ADS)

In large institution PACS, patient data may often reside in multiple separate systems. While most systems tend to be DICOM compliant, none of them offer the flexibility of seamless integration of multiple DICOM sources through a single access point. We developed a generic portal system with a web-based interactive front-end as well as an application programming interface (API) that allows both web users and client applications to query and retrieve image data from multiple DICOM sources. A set of software tools was developed to allow accessing several DICOM archives through a single point of access. An interactive web-based front-end allows user to search image data seamlessly from the different archives and display the results or route the image data to another DICOM compliant destination. An XML-based API allows other software programs to easily benefit from this portal to query and retrieve image data as well. Various techniques are employed to minimize the performance overhead inherent in the DICOM. The system is integrated with a hospital-wide HIPAA-compliant authentication and auditing service that provides centralized management of access to patient medical records. The system is provided under open source free licensing and developed using open-source components (Apache Tomcat for web server, MySQL for database, OJB for object/relational data mapping etc.). The portal paradigm offers a convenient and effective solution for accessing multiple image data sources in a given healthcare enterprise and can easily be extended to multi-institution through appropriate security and encryption mechanisms.

Liver stiffness and the prediction of clinically significant portal hypertension and portal hypertensive complications.  

PubMed

Abstract Objective. Clinically significant portal hypertension (CSPH) is associated with increased risk of liver disease complications, but its identification requires invasive methods. Liver stiffness (LS) measurement via transient elastography correlates with the presence of CSPH. We, therefore, evaluated LS as a noninvasive tool in the prediction of CSPH and portal hypertensive complications. Material and methods. Ninety-five consecutive patients successfully underwent measurement of hepatic venous pressure gradient (HVPG) and LS on the same day. Recent laboratory tests were correlated. Patients were followed up for development of portal hypertensive complications. Predictors of CSPH and complications were identified. Results. Seventy-six (80%) were male and mean age was 56.8 ± 9.3 years. Ninety-three percent and 72% of patients had cirrhosis and esophageal varices, respectively. Only LS (r(2) = 0.38; p < 0.0001) and international normalized ratio (r(2) = 0.21; p = 0.02) were independently associated with HVPG. An LS >29.0 kilopascal (kPa) predicted CSPH with 71.9% sensitivity, 100% specificity, 100% positive predictive value (PPV), and 56.0% negative predictive value (NPV). An LS <25.0 kPa in those with platelet count >150 × 10(9)/L excluded CSPH with 91.7% sensitivity, 100% specificity, 100% PPV, and 90% NPV. Ninety patients were followed up for a median duration of 15.1 months. CSPH and LS >34.5 kPa predicted portal hypertensive complications with 100% and 75.0% sensitivity, 40.3% and 69.4% specificity, 43.1% and 52.5% PPV, and 100% and 86.2% NPV, respectively. Conclusion. LS shows promise as a noninvasive marker of CSPH and portal hypertensive complications. Combining LS with platelet count improves diagnostic accuracy in the exclusion of CSPH. PMID:25623641

Palliative Portal Vein Stent Placement in Malignant and Symptomatic Extrinsic Portal Vein Stenosis or Occlusion  

SciTech Connect

This article evaluates the results of portal vein (PV) stent placement in patients with malignant extrinsic lesions stenosing or obstructing the PV and causing symptomatic PV hypertension (PVHT). Fourteen patients with bile duct cancer (n = 7), pancreatic adenocarcinoma (n = 4), or another cancer (n = 3) underwent percutaneous transhepatic portal venous stent placement because of gastroesophageal or jejunal varices (n = 9), ascites (n = 7), and/or thrombocytopenia (n = 2). Concurrent tumoral obstruction of the main bile duct was treated via the transhepatic route in the same session in four patients. Changes in portal venous pressure, complications, stent patency, and survival were evaluated. Mean {+-} standard deviation (SD) gradient of portal venous pressure decreased significantly immediately after stent placement from 11.2 mmHg {+-} 4.6 to 1.1 mmHg {+-} 1.0 (P < 0.00001). Three patients had minor complications, and one developed a liver abscess. During a mean {+-} SD follow-up of 134.4 {+-} 123.3 days, portal stents remained patent in 11 patients (78.6%); stent occlusion occurred in 3 patients, 2 of whom had undergone previous major hepatectomy. After stent placement, PVHT symptoms were relieved in four (57.1%) of seven patients who died (mean survival, 97 {+-} 71.2 days), and relieved in six (85.7%) of seven patients still alive at the end of follow-up (mean follow-up, 171.7 {+-} 153.5 days). Stent placement in the PV is feasible and relatively safe. It helped to relieve PVHT symptoms in a single session.

METHODS: Glytan (Ganluotong in Chinese), is composed of salvianolic acid B and diammonium glycyrrhizinate. Portal hypertension (PHT) was induced in the rats by common bile duct ligation (BDL). Hemodynamic studies were performed using the colored microsphere method. Radioimmunoassay (RIA) was used to determine endothelin (ET)-1 levels in the mesenteric circulation. Western blotting methods were used to investigate the effect of Glytan on ET A receptor (ETAR), ET B receptor (ETBR), endothelial NO synthase (eNOS), G-protein-coupled receptor kinase (GRK)2, and ?-arrestin 2 expression in the mesentery. The mRNA of ETAR and ETBR was determined using real-time polymerase chain reaction. RESULTS: Treatment with Glytan reduced portal pressure (PP) and portal territory blood flow (PTBF) and increased both mean arterial pressure (MAP) and splanchnic vascular resistance (SVR). Especially at 4 wk, PP decreased by about 40%, while MAP increased by 13%, SVR increased by 12%, and PTBF decreased by about 21%. The effect of blood flow reduction was greatest in the mesentery (about 33%) at 4 wk. The mesenteric circulation ET-1 levels of BDL rats were lower and negatively correlated with PP at 4 wk. Glytan can increase mesenteric ET-1 content and inhibit ETBR, eNOS, GRK2, and ?-arrestin 2 expression in the mesentery. Moreover, Glytan showed no effect on the expression of ETAR protein and mRNA. CONCLUSION: The decreased PP and PTBF observed after Glytan treatment were related to increased mesenteric vasoconstriction and increased receptor sensitivity to vasoconstrictor. PMID:25469036

Peculiar characteristics of portal-hepatic hemodynamics of alcoholic cirrhosis  

PubMed Central

Alcohol-related cirrhosis is a consequence of heavy and prolonged drinking. Similarly to patients with cirrhosis of other etiologies, patients with alcoholic cirrhosis develop portal hypertension and the hepatic, splanchnic and systemic hemodynamic alterations that follow. However, in alcoholic cirrhosis, some specific features can be observed. Compared to viral cirrhosis, in alcohol-related cirrhosis sinusoidal pressure is generally higher, hepatic venous pressure gradient reflects portal pressure better, the portal flow perfusing the liver is reduced despite an increase in liver weight, the prevalence of reversal portal blood flow is higher, a patent paraumbilical vein is a more common finding and signs of hyperdynamic circulations, such as an increased cardiac output and decreased systemic vascular resistance, are more pronounced. Moreover, alcohol consumption can acutely increase portal pressure and portal-collateral blood flow. Alcoholic cardiomyopathy, another pathological consequence of prolonged alcohol misuse, may contribute to the hemodynamic changes occurring in alcohol-related cirrhosis. The aim of this review was to assess the portal-hepatic changes that occur in alcohol-related cirrhosis, focusing on the differences observed in comparison with patients with viral cirrhosis. The knowledge of the specific characteristics of this pathological condition can be helpful in the management of portal hypertension and its complications in patients with alcohol-related cirrhosis.

Inflammation: a way to understanding the evolution of portal hypertension  

PubMed Central

Background Portal hypertension is a clinical syndrome that manifests as ascites, portosystemic encephalopathy and variceal hemorrhage, and these alterations often lead to death. Hypothesis Splanchnic and/or systemic responses to portal hypertension could have pathophysiological mechanisms similar to those involved in the post-traumatic inflammatory response. The splanchnic and systemic impairments produced throughout the evolution of experimental prehepatic portal hypertension could be considered to have an inflammatory origin. In portal vein ligated rats, portal hypertensive enteropathy, hepatic steatosis and portal hypertensive encephalopathy show phenotypes during their development that can be considered inflammatory, such as: ischemia-reperfusion (vasodilatory response), infiltration by inflammatory cells (mast cells) and bacteria (intestinal translocation of endotoxins and bacteria) and lastly, angiogenesis. Similar inflammatory phenotypes, worsened by chronic liver disease (with anti-oxidant and anti-enzymatic ability reduction) characterize the evolution of portal hypertension and its complications (hepatorenal syndrome, ascites and esophageal variceal hemorrhage) in humans. Conclusion Low-grade inflammation, related to prehepatic portal hypertension, switches to high-grade inflammation with the development of severe and life-threatening complications when associated with chronic liver disease.

Evaluating User Experiences of the Secure Messaging Tool on the Veterans Affairs’ Patient Portal System  

PubMed Central

Background The United States Department of Veterans Affairs has implemented an electronic asynchronous “Secure Messaging” tool within a Web-based patient portal (ie, My HealtheVet) to support patient-provider communication. This electronic resource promotes continuous and coordinated patient-centered care, but to date little research has evaluated patients’ experiences and preferences for using Secure Messaging. Objective The objectives of this mixed-methods study were to (1) characterize veterans’ experiences using Secure Messaging in the My HealtheVet portal over a 3-month period, including system usability, (2) identify barriers to and facilitators of use, and (3) describe strategies to support veterans’ use of Secure Messaging. Methods We recruited 33 veterans who had access to and had previously used the portal’s Secure Messaging tool. We used a combination of in-depth interviews, face-to-face user-testing, review of transmitted secure messages between veterans and staff, and telephone interviews three months following initial contact. We assessed participants’ computer and health literacy during initial and follow-up interviews. We used a content-analysis approach to identify dominant themes in the qualitative data. We compared inferences from each of the data sources (interviews, user-testing, and message review) to identify convergent and divergent data trends. Results The majority of veterans (27/33, 82%) reported being satisfied with Secure Messaging at initial interview; satisfaction ratings increased to 97% (31/32, 1 missing) during follow-up interviews. Veterans noted Secure Messaging to be useful for communicating with their primary care team to manage health care needs (eg, health-related questions, test requests and results, medication refills and questions, managing appointments). Four domains emerged from interviews: (1) perceived benefits of using Secure Messaging, (2) barriers to using Secure Messaging, (3) facilitators for using Secure Messaging, and (4) suggestions for improving Secure Messaging. Veterans identified and demonstrated impediments to successful system usage that can be addressed with education, skill building, and system modifications. Analysis of secure message content data provided insights to reasons for use that were not disclosed by participants during interviews, specifically sensitive health topics such as erectile dysfunction and sexually transmitted disease inquiries. Conclusions Veterans perceive Secure Messaging in the My HealtheVet patient portal as a useful tool for communicating with health care teams. However, to maximize sustained utilization of Secure Messaging, marketing, education, skill building, and system modifications are needed. Data from this study can inform a large-scale quantitative assessment of Secure Messaging users’ experiences in a representative sample to validate qualitative findings. PMID:24610454

Portal vein thrombosis: what is new?  

PubMed

Portal vein thrombosis (PVT) is one of the most common vascular disorders of the liver with significant morbidity and mortality. Large cohort studies have reported a global prevalence of 1%, but in some risk groups it can be up to 26%. Causes of PVT are cirrhosis, hepatobiliary malignancy, abdominal infectious or inflammatory diseases, and myeloproliferative disorders. Most patients with PVT have a general risk factor. The natural history of PVT results in portal hypertension leading to splenomegaly and the formation of portosystemic collateral blood vessels and esophageal, gastric, duodenal, and jejunal varices. Diagnosis of PVT is made by imaging, mainly Doppler ultrasonography. According to its time of development, localization, pathophysiology, and evolution, PVT should be classified in every patient. Some clinical features such as cirrhosis, hepatocellular carcinoma, and hepatic transplantation are areas of special interest and are discussed in this review. The goal of treatment of acute PVT is to reconstruct the blocked veins. Endoscopic variceal ligation is safe and highly effective in patients with variceal bleeding caused by chronic PVT. In conclusion, PVT is the most common cause of vascular disease of the liver and its prevalence has being increasing, especially among patients with an underlying liver disease. All patients should be investigated for thrombophilic conditions, and in those with cirrhosis, anticoagulation prophylaxis should be considered. PMID:25536638

Perturbative Unitarity Constraints on Gauge Portals  

E-print Network

Dark matter that was once in thermal equilibrium with the Standard Model is generally prohibited from obtaining all of its mass from the electroweak phase transition. This implies a new scale of physics and mediator particles to facilitate dark matter annihilation. In this work, we focus on dark matter that annihilates through a generic gauge boson portal. We show how partial wave unitarity places upper bounds on the dark gauge boson, dark Higgs and dark matter masses. Outside of well-defined fine-tuned regions, we find an upper bound of 9 TeV for the dark matter mass when the dark Higgs and dark gauge bosons both facilitate the dark matter annihilations. In this scenario, the upper bound on the dark Higgs and dark gauge boson masses are 10 TeV and 16 TeV, respectively. When only the dark gauge boson facilitates dark matter annihilations, we find an upper bound of 3 TeV and 6 TeV for the dark matter and dark gauge boson, respectively. Overall, using the gauge portal as a template, we describe a method to not only place upper bounds on the dark matter mass but also on the new particles with Standard Model quantum numbers. We briefly discuss the reach of future accelerator, direct and indirect detection experiments for this class of models.

Software tool for portal dosimetry research.  

PubMed

This paper describes a software tool developed for research into the use of an electronic portal imaging device (EPID) to verify dose for intensity modulated radiation therapy (IMRT) beams. A portal dose image prediction (PDIP) model that predicts the EPID response to IMRT beams has been implemented into a commercially available treatment planning system (TPS). The software tool described in this work was developed to modify the TPS PDIP model by incorporating correction factors into the predicted EPID image to account for the difference in EPID response to open beam radiation and multileaf collimator (MLC) transmitted radiation. The processes performed by the software tool include; i) read the MLC file and the PDIP from the TPS, ii) calculate the fraction of beam-on time that each point in the IMRT beam is shielded by MLC leaves, iii) interpolate correction factors from look-up tables, iv) create a corrected PDIP image from the product of the original PDIP and the correction factors and write the corrected image to file, v) display, analyse, and export various image datasets. The software tool was developed using the Microsoft Visual Studio.NET framework with the C# compiler. The operation of the software tool was validated. This software provided useful tools for EPID dosimetry research, and it is being utilised and further developed in ongoing EPID dosimetry and IMRT dosimetry projects. PMID:18946980

Natural History of Portal Cavernoma Cholangiopathy  

PubMed Central

The natural history of portal cavernoma cholangiopathy (PCC) is poorly defined and poorly understood. It develops early after acute portal vein thrombosis (PVT) if there is failure of recanalization. In PCC, the likelihood of progression of biliary abnormalities after 1 year is extremely low. The natural history of PCC is conveniently divided into asymptomatic and symptomatic stages. The majority of patients with PCC are asymptomatic and are detected incidentally on imaging. Limited data suggest that asymptomatic PCC is static or only slowly progressive in the initial stages. However, most workers agree that, overall, PCC is a slowly progressive disease. Symptomatic PCC represents a late stage in its natural history. Finding strictures with dilatation at cholangiography is associated with a higher risk of developing symptoms of PCC. Onset of symptoms is often precipitated by the development of biliary sludge or calculi and treating calculi usually relieves symptoms for prolonged periods of time. Clinical presentations include biliary pain, obstructive jaundice, acute cholangitis, acute cholecystitis, or other presentations of gallstone disease. Progressive liver dysfunction and secondary biliary cirrhosis can develop in a minority of patients. PMID:25755597

Portal Hypertension as Immune Mediate Disease  

PubMed Central

Context: Portal Hypertension (PH) is a progressive complication due to chronic liver disease. In addition to pathophysiologic changes in the micro-circulation, in PH are established fibrous tissue (periportal fibrous septal) and regenerative hyperplastic nodules (from micro- to macro-nodules) promoting hepatic architectural distortion. Evidence Acquisition: A literature search of electronic databases was undertaken for the major studies published from 1981 to today. The databases searched were: PubMed, EMBASE, Orphanet, Midline and Cochrane Library. We used the keywords: "portal hypertension, children, immune system, endocrine system, liver fibrosis". Results: It is believed that PH results from three “phenotype”: ischemia-reperfusion, involving nervous system (NS); edema and oxidative damage, involving immune system; inflammation and angiogenesis, involving endocrine system. However, its exact cause still underdiagnosed and unknown. Conclusions: PH is a dynamic and potentially reversible process. Researchers have tried to demonstrate mechanisms underlying PH and its related-complications. This review focuses on the current knowledge regarding the pathogenesis, and immune, endocrine-metabolic factors of disease. The strong positive association between immune system and development of PH could be efficient to identify non-invasive markers of disease, to modify prognosis of PH, and to development and application of specific and individual anti-inflammatory therapy.

Splanchnic-aortic inflammatory axis in experimental portal hypertension  

PubMed Central

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.

Education  

NASA Astrophysics Data System (ADS)

Government schools in Congo kinshasa are not providing quality education to the masses since many years, and this phenomenon has not escaped the eyes of experts, activists, and policy makers. However, there seems to be a general perception that the main, and sometimes even the sole, source of this problem are the low levels of government expenditure of education. And to prove their case supports of this view cite educational expenditure to GDP ratios in Congo kinshasa in comparison with that of some other nations. Though there may be reasonable arguments to increase the level of government expenditure on education, such hijacking of public debate to focus on - the level of expenditure - often overlooks more important issues. Contrary to common perception the level of per student expenditure on government schools in Delhi is reasonable, ranging from Fc.6000 to Fc.12000 p.a. There are a number of organisational deficiencies which do not create checks and balances for appropriate utilization of fund. Moreover, the division of these funds among social groups and for different purposes is also questionable. Though, female literacy lags significantly behind male literacy, about 15% points, extra resources provided for female education are insignificant. And in some schemes such as the one run for 'street children' and 'child labourers', large amounts are budgeted year after year without a single French congolese being spent. Also government schools catering to richer regions of Kinshasa seem to be spending more per child as compared to the poorer counterparts. The paper also proposes an education voucher model, which may have the potential to address some of the issues raised in the paper. Trends in expenditure under some schemes have been studied in relation to the purpose of expenditure. The issue of government expenditure on education is a complex one, and public space should be utilized to discuss them as they are, rather than reducing discussion to dogmatic wars aimed at increasing the levels of expenditure. Though, one may agree or disagree with the methods and findings of the author, hopefully the paper highlight the complexity of the issue at hand, and the need to understand the institutional deficiencies and allocative inefficiencies in government expenditure on education.

[Portal vein stenting as a bridge to chemotherapy for perihilar cancer with portal vein stenosis - a case report].  

PubMed

The stenting strategy for portal vein stenosis in cases with unresectable hilar malignancies reduces portal hypertension and maintains portal vein blood flow. This not only improves quality of life, but also leads to aggressive therapy with anticancer agents. A 65-year-old woman presented with painless jaundice 8 months after left hemihepatectomy with lymph node dissection for intrahepatic cholangiocellular carcinoma. Seven months after biliary stenting for bile duct stenosis, progressing pancytopenia and ascites were noted. Imaging studies revealed portal vein stenosis by the tumor at the hepatic hilum. Percutaneous transhepatic portal vein stent placement was performed, and pancytopenia and ascites improved immediately thereafter. Chemotherapy for recurrence of intrahepatic cholangiocellular carcinoma at the hepatic hilum has been initiated, and the patient has been alive 15 months since. PMID:25731245

The National Oceanic and Atmospheric Administration (NOAA) Climate Services Portal: A New Centralized Resource for Distributed Climate Information  

NASA Astrophysics Data System (ADS)

With the rapid rise in the development of Web technologies and climate services across NOAA, there has been an increasing need for greater collaboration regarding NOAA's online climate services. The drivers include the need to enhance NOAA's Web presence in response to customer requirements, emerging needs for improved decision-making capabilities across all sectors of society facing impacts from climate variability and change, and the importance of leveraging climate data and services to support research and public education. To address these needs, NOAA (during fiscal year 2009) embarked upon an ambitious program to develop a NOAA Climate Services Portal (NCS Portal). Four NOAA offices are leading the effort: 1) the NOAA Climate Program Office (CPO), 2) the National Ocean Service's Coastal Services Center (CSC), 3) the National Weather Service's Climate Prediction Center (CPC), and 4) the National Environmental Satellite, Data, and Information Service's (NESDIS) National Climatic Data Center (NCDC). Other offices and programs are also contributing in many ways to the effort. A prototype NCS Portal is being placed online for public access in January 2010, http://www.climate.gov. This website only scratches the surface of the many climate services across NOAA, but this effort, via direct user engagement, will gradually expand the scope and breadth of the NCS Portal to greatly enhance the accessibility and usefulness of NOAA's climate data and services.

Zero tolerance. With health IT money up for grabs, many EHR vendors are offering financing deals to attract business. But, just like shopping for a car, experts warn about reading the fine print before buying.

The government, by way of federal stimulus incentives, wants to boost the use of electronic health records. However, physician practices must be careful about low or no-interest offers when buying an EHR system, experts say. "The ultimate power a buyer has--I use the analogy of buying a car--is the ability to say 'no thanks' and walk out of the showroom", says Steven Fox, left, a partner at Post & Schell. PMID:20336867

Enabling OpenID Authentication for VO-integrated Portals  

NASA Astrophysics Data System (ADS)

To support interoperating services that share proprietary data and other user-specific information, the VAO Project provides login services for browser-based portals built on the open standard, OpenID. To help portal developers take advantage of this service, we have developed a downloadable toolkit for integrating OpenID single sign-on support into any portal. This toolkit provides APIs in a few languages commonly used on the server-side as well as a command-line version for use in any language. In addition to describing how to use this toolkit, we also discuss the general VAO framework for single sign-on. While a portal may, if it wishes, support any OpenID provider, the VAO service provides a few extra features to support VO interoperability. This includes a portal's ability to retrieve (with the user's permission) an X.509 certificate representing the authenticated user so that the portal can access other restricted services on the user's behalf. Other standard features of OpenID allow portals to request other information about the user; this feature will be used in the future for sharing information about a user's group membership to enable sharing within a group of collaborating scientists.

Utility of endoscopic ultrasound in patients with portal hypertension  

PubMed Central

Endoscopic ultrasound (EUS) has revolutionized the diagnostic and therapeutic approach to patients with gastrointestinal disorders. Its application in patients with liver disease and portal hypertension is increasing. Patients with chronic liver disease are at risk for development of portal hypertension sequale such as ascites, spontaneous bacterial peritonitis and gastroesophageal varices. Bleeding esophageal and gastric varices are among the most common causes of mortality in patients with cirrhosis. Thus, early detection and treatment improve the outcome in this population. EUS can improve the detection and diagnosis of gastroesophageal varices and collateral veins and can provide endoscopic therapy of gastroesophageal varices such as EUS-guided sclerotherapy of esophageal collateral vessels and EUS-guided cynoacrylate (Glue) injection of gastric varices. EUS can also provide knowledge on the efficacy of pharmacotherapy of portal hypertension. Furthermore, EUS can provide assessment and prediction of variceal recurrence after endoscopic therapy and assessment of portal hemodynamics such as E-Flow and Doppler study of the azygous and portal veins. Moreover, EUS-guided fine needle aspiration may provide cytologic diagnosis of focal hepatic tumors and analysis of free abdominal fluid. Using specialized EUS-guided needle biopsy, a sample of liver tissue can be obtained to diagnose and evaluate for chronic liver disease. EUS-guided fine needle injection can be used to study portal vein pressure and hemodynamics, and potentially could be used to assist in exact measurement of portal vein pressure and placement of intrahepatic portosystemic shunt.
