Provenance: Promise and Practice  

NASA Astrophysics Data System (ADS)

Capturing provenance is one of the fundamental principles of archive theory. Provenance consists of information about the creation of an object, its ownership, and how this information has changed over time. The data management community has been discussing how to apply the concepts of provenance to science data. Considerable attention has been paid to developing mechanisms to record how data were created, since this is key to reproducing research results. Less attention has been paid to the other elements of provenance, even though data and the organizations that archive data are dynamic and ever changing. Some practice is coming into play; but there is a large gap between theory and practice. This talk will review the current state of the art, discuss the gap between theory and practice, and describe what could be done to close the gap.

Practice coaching, also called practice facilitation, assists physician practices with the desire to improve in such areas as patient access, chronic and preventive care, electronic medical record use, patient-centeredness, cultural competence, and team-building. This issue brief clarifies the essential features of practice coaching and offers guidance for health system leaders, public and private insurers, and federal and state policymakers on how best to structure and design these programs in primary care settings. Good-quality evidence demonstrates that practice coaching is effective. The authors argue that primary care delivery in the United States would benefit from a more systematic approach to the training and deployment of primary care practice coaches. PMID:22712103

Response to Intervention (RtI) Model: a promising alternative for identifying students with learning disabilities?  

PubMed

Until recently, in the United States, the traditional way to identify students with Specific Learning Disabilities (SLD) was through the discrepancy model where student IQs were compared to their level of achievement. However, educators and researchers alike have questioned this model as a means to define and identify students with SLD. The 2004 reauthorization of the Individuals with Disabilities Education Improvement Act (IDEIA) includes the use of response to intervention (RtI) as possible alternative to the intelligence-achievement discrepancy for identifying SLD. Core components of RtI include high-quality classroom instruction, universal screening, continuous progress monitoring, research-based interventions, and fidelity of instructional interventions. In Spain, the last publication of Ley Orgánica 2/2006, May 3, of Education (LOE) uses the term, Specific Learning Disabilities (SLD), in the chapter on students with specific needs of educational support. Some Autonomous Communities in Spain like the Canary Islands region are regulating SLD identification that adds RtI as an option to use in the eligibility process. Nevertheless, this model it is still at an embryonic stage and many issues are unresolved. While no special issue can cover all of these themes and issues, the contributions included in this monograph examine relevant aspects of this approach. Indeed, this special section is an attempt to introduce in Spain an approach that could be an alternative for identifying and intervening with students who have learning disabilities. PMID:21044534

Partnership and measurement: the promise, practice and theory of a successful health social networking strategy.  

PubMed

Patient health management (PHM) was launched as a promising paradigm to close care gaps, the inequities between usual and best care, for whole patient populations. PHM's core premise was that interventions of multidisciplinary, community-oriented partnerships that used repeated measurement and feedback of provider practices, clinical and economic outcomes and general communication of relevant health knowledge to all stakeholders would continuously make things better. This article reviews the evolution of PHM from its genesis in a series of casual hospital-based networks to its maturation in a province-wide, community-focused, clustered-lattice social network that facilitated the improved clinical and cost-efficient care and outcomes of whole patient populations. The factors underlying PHM's clinical and cost efficacy, specifically its patient-centric social networking structures and integral measurement and knowledge translation processes, offer continuing promise to optimally manage the care of our increasingly aged patient populations, with their high burden of chronic diseases and disproportionately large care gaps. In an era when patients are demanding and leading change, and governments are struggling fiscally, PHM's clinical efficacy and cost-efficiency are especially resonant. Things can be better.

Innovations at Miami practice show promise for treating high-risk Medicare patients.  

PubMed

Patients with five or more chronic conditions drive most Medicare costs. Our organization, ChenMed, developed a scalable primary care-led delivery model that focuses on this population while getting reimbursed through full-risk capitation by Medicare Advantage plans. ChenMed is a primary care-led group practice based in Florida that serves low-to-moderate-income elderly patients, largely through the Medicare Advantage program. Our model includes a number of innovations: a one-stop-shop approach for delivering multispecialty services in the community, smaller physician panel sizes of 350-450 patients that allow for intensive health coaching and preventive care, on-site physician pharmacy dispensing, a collaborative physician culture with peer review, and customized information technology. These innovations have improved patient medication adherence, increased the time doctors and patients spend together, and led to high rates of patient satisfaction. Additionally, our Medicare patients have substantially lower rates of hospital use than their peers in the Miami Medicare market. Creating chronic disease centers focused on seniors with multiple chronic conditions is a promising delivery system innovation with major potential to improve the cost and quality of care.

The frontline clinical manager identifying direct reports' level of practice.  

PubMed

Patricia Benner applied the Dreyfus Model of Skill Acquisition to describe and interpret skill acquisition and clinical judgment in nursing practice. Operational definitions for the 5 levels of her original Novice to Expert Theory were used by the study participants in a large Midwestern pediatric hospital to self-identify their level of practice. The frontline clinical managers of these direct care registered nurses (RNs) used the same tool to rate their direct reports. The aim of this portion of a larger study was to determine if the clinical manager's perception of their direct reports was the same as that of the RNs. The results of this study are being used by one study unit's clinical managers as the basis for implementing the Hersey and Blanchard Situational Leadership Model. The clinical managers work with their direct reports depending on the level of practice and the details of the task to be performed. One example is creating therapeutic relationships with each other and with families to ensure a safe environment for all. PMID:23934257

Practical identifiability of finite mixtures of multivariate bernoulli distributions.  

PubMed

The class of finite mixtures of multivariate Bernoulli distributions is known to be nonidentifiable; that is, different values of the mixture parameters can correspond to exactly the same probability distribution. In principle, this would mean that sample estimates using this model would give rise to different interpretations. We give empirical support to the fact that estimation of this class of mixtures can still produce meaningful results in practice, thus lessening the importance of the identifiability problem. We also show that the expectation-maximization algorithm is guaranteed to converge to a proper maximum likelihood estimate, owing to a property of the log-likelihood surface. Experiments with synthetic data sets show that an original generating distribution can be estimated from a sample. Experiments with an electropalatography data set show important structure in the data. PMID:10636936

How the practice of allergy shows the promise and challenge of personalized medicine.  

PubMed

Personalized medicine seeks to stratify therapies according to individual characteristics, and by so doing improve effectiveness and reduce complications. However, there are not many models of care that is highly stratified within a single diagnosis in this manner. One potential model is the practice of allergy, in which care is tailored to specific allergens for individual patients within the broader context of care for rhinitis or asthma. Allergists have already confronted many of the same regulatory issues anticipated for personalized medicine. The history of allergy practice also anticipates some of the patient safety concerns that may arise from tracking and using highly personalized medical information. Finally, the therapy of allergy and asthma has been at the forefront of attempts to incorporate pharmacogenomics information into patient care. Individualized therapy has always been central to the practice of allergy, and so provides a useful proving ground for personalized medicine as a concept of care. PMID:21810545

The doctor of nursing practice and nursing education: highlights, potential, and promise.  

PubMed

The success of the doctor of nursing practice (DNP) programs have exceeded everyone's expectations and resulted in increased interest in doctoral education in nursing. A shortage of doctorally prepared nurse educators continues to plague the profession and has a severe impact on the ability of schools of nursing to educate future generations of nurses. As a terminal degree in nursing practice, there is little focus on DNP graduates who are prepared as educators. To remedy this deficit, this article will therefore discuss and highlight (a) the significant potential of the DNP to mitigate the current nursing faculty shortage and to close the practice-education gap, (b) the specialized role of DNP graduates as educators and leaders in nursing education, and (c) the implications of the DNP for nursing scholarship.

Keeping Promises  

NASA Technical Reports Server (NTRS)

Commitments are between people, not schedules. Project management as practiced today creates a "commitment-free zone," because it assumes that people will commit to centrally managed schedules without providing a mechanism to ensure their work can be done. So they give it their best, but something always seems to come up ..."I tried, but you know how it is." This form of project management does not provide a mechanism to ensure that what should be done, can in fact be done at the required moment. Too often, promises reliable promise. made in coordination meetings are conditional and unreliable. It has been my experience that at times trust can be low and hard to build in this environment. The absence of reliable promises explains why on well-run projects, people are often only completing 30-50 percent of the deliverables they d promised for the week. We all know what a promise is; we have plenty of experience making them and receiving them from others. So what s the problem? The sad fact is that the project environment-like many other work environments- is often so filled with systemic dishonesty, that we don t expect promises that are reliable. Project managers excel when they manage their projects as networks of commitments and help their people learn to elicit and make reliable promises.

Promise and dismay: The state of strategic environmental assessment systems and practices in Canada  

SciTech Connect

Has strategic environmental assessment (SEA) finally reached a point of maturity in Canada? Or, is it still stumbling to find its place in the impact assessment family? Strategic environmental assessment has been ongoing in Canada for a number of years, both formally and informally, and under a variety of labels and institutional models. The result is a system of SEA that is diverse, founded on a range of principles and frameworks, and not well understood. This paper provides a critical review of Canadian SEA systems and practices. To accomplish this objective, a manageable and diverse set of past and recent SEA and SEA-like frameworks and applications are described and critically analyzed based on a set of input, process, and output evaluation criteria. Results suggest considerable variability in SEA experience and value added. This is due in large part to the institutional and methodological pluralism of SEA, the boundaries of which are not well defined. Under the federal system, since the formalization of SEA, many applications have been disappointing in light of broader SEA good-practice principles and criteria. Indeed, some of the better examples of SEA have neither carried the SEA name tag nor occurred under formal SEA requirements. Further, many of the same challenges to project-based impact assessment also plague the development and value added of SEA. Of particular concern is the systematic separation of SEA from downstream decision inputs and assessment activities. As Canada commences review of its federal SEA Directive in preparation for the next generation of SEA, this paper reflects on what it has achieved in the prior.

Genome Wide Association Study Identifies 20 Novel Promising Genes Associated with Milk Fatty Acid Traits in Chinese Holstein  

PubMed Central

Detecting genes associated with milk fat composition could provide valuable insights into the complex genetic networks of genes underling variation in fatty acids synthesis and point towards opportunities for changing milk fat composition via selective breeding. In this study, we conducted a genome-wide association study (GWAS) for 22 milk fatty acids in 784 Chinese Holstein cows with the PLINK software. Genotypes were obtained with the Illumina BovineSNP50 Bead chip and a total of 40,604 informative, high-quality single nucleotide polymorphisms (SNPs) were used. Totally, 83 genome-wide significant SNPs and 314 suggestive significant SNPs associated with 18 milk fatty acid traits were detected. Chromosome regions that affect milk fatty acid traits were mainly observed on BTA1, 2, 5, 6, 7, 9, 13, 14, 18, 19, 20, 21, 23, 26 and 27. Of these, 146 SNPs were associated with more than one milk fatty acid trait; most of studied fatty acid traits were significant associated with multiple SNPs, especially C18:0 (105 SNPs), C18 index (93 SNPs), and C14 index (84 SNPs); Several SNPs are close to or within the DGAT1, SCD1 and FASN genes which are well-known to affect milk composition traits of dairy cattle. Combined with the previously reported QTL regions and the biological functions of the genes, 20 novel promising candidates for C10:0, C12:0, C14:0, C14:1, C14 index, C18:0, C18:1n9c, C18 index, SFA, UFA and SFA/UFA were found, which composed of HTR1B, CPM, PRKG1, MINPP1, LIPJ, LIPK, EHHADH, MOGAT1, ECHS1, STAT1, SORBS1, NFKB2, AGPAT3, CHUK, OSBPL8, PRLR, IGF1R, ACSL3, GHR and OXCT1. Our findings provide a groundwork for unraveling the key genes and causal mutations affecting milk fatty acid traits in dairy cattle.

Global tyrosine kinome profiling of human thyroid tumors identifies Src as a promising target for invasive cancers  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Kinome profiling is a novel technique for identifying activated kinases in human cancers. Black-Right-Pointing-Pointer Src activity is increased in invasive thyroid cancers. Black-Right-Pointing-Pointer Inhibition of Src activity decreased proliferation and invasion in vitro. Black-Right-Pointing-Pointer Further investigation of Src targeted therapies in thyroid cancer is warranted. -- Abstract: Background: Novel therapies are needed for the treatment of invasive thyroid cancers. Aberrant activation of tyrosine kinases plays an important role in thyroid oncogenesis. Because current targeted therapies are biased toward a small subset of tyrosine kinases, we conducted a study to reveal novel therapeutic targets for thyroid cancer using a bead-based, high-throughput system. Methods: Thyroid tumors and matched normal tissues were harvested from twenty-six patients in the operating room. Protein lysates were analyzed using the Luminex immunosandwich, a bead-based kinase phosphorylation assay. Data was analyzed using GenePattern 3.0 software and clustered according to histology, demographic factors, and tumor status regarding capsular invasion, size, lymphovascular invasion, and extrathyroidal extension. Survival and invasion assays were performed to determine the effect of Src inhibition in papillary thyroid cancer (PTC) cells. Results: Tyrosine kinome profiling demonstrated upregulation of nine tyrosine kinases in tumors relative to matched normal thyroid tissue: EGFR, PTK6, BTK, HCK, ABL1, TNK1, GRB2, ERK, and SRC. Supervised clustering of well-differentiated tumors by histology, gender, age, or size did not reveal significant differences in tyrosine kinase activity. However, supervised clustering by the presence of invasive disease showed increased Src activity in invasive tumors relative to non-invasive tumors (60% v. 0%, p < 0.05). In vitro, we found that Src inhibition in PTC cells decreased cell invasion and proliferation. Conclusion: Global kinome analysis enables the discovery of novel targets for thyroid cancer therapy. Further investigation of Src targeted therapy for advanced thyroid cancer is warranted.

Eliminating tobacco-related disparities among Pacific Islanders through leadership and capacity building: promising practices and lessons learned.  

PubMed

Tobacco remains a major risk factor for premature death and ill health among Pacific Islanders, and tobacco-related disparities persist. Eliminating these disparities requires a comprehensive approach to transform community norms about tobacco use through policy change, as contained in the World Health Organization international Framework Convention on Tobacco Control. Three of the six U.S.-affiliated Pacific Islands-the Federated States of Micronesia, Palau, and the Marshall Islands-are Parties to the Framework; the remaining three territories-American Samoa, the Commonwealth of the Northern Mariana Islands, and Guam-are excluded from the treaty by virtue of U.S. nonratification. Capacity building and leadership development are essential in achieving policy change and health equity within Pacific Islander communities. We describe promising practices from American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, Guam, and Palau and highlight some of the key lessons learned in supporting and sustaining the reduction in tobacco use among Pacific Islanders as the first step toward eliminating tobacco-related disparities in these populations.

Identifying industrial best practices for the waste minimization of low-level radioactive materials  

SciTech Connect

In US DOE, changing circumstances are affecting the management and disposal of solid, low-level radioactive waste (LLW). From 1977 to 1991, the nuclear power industry achieved major reductions in solid waste disposal, and DOE is interested in applying those practices to reduce solid waste at DOE facilities. Project focus was to identify and document commercial nuclear industry best practices for radiological control programs supporting routine operations, outages, and decontamination and decommissioning activities. The project team (DOE facility and nuclear power industry representatives) defined a Work Control Process Model, collected nuclear power industry Best Practices, and made recommendations to minimize LLW at DOE facilities.

A Genome-Wide Association Study Identifies Two Novel Promising Candidate Genes Affecting Escherichia coli F4ab/F4ac Susceptibility in Swine  

PubMed Central

Enterotoxigenic Escherichia coli (ETEC) expressing F4 fimbria is the major pathogenic bacteria causing diarrhoea in neonatal and post-weaning piglets. Previous studies have revealed that the susceptibility to ETEC F4ab/F4ac is an autosomal Mendelian dominant trait and the loci controlling the F4ab/F4ac receptor are located on SSC13q41, between markers SW207 and S0283. To pinpoint these loci and further validate previous findings, we performed a genome-wide association study (GWAS) using a two generation family-based population, consisting of 301 piglets with phenotypes of susceptibility to ETEC F4ab/F4ac by the vitro adhesion test. The DNA of all piglets and their parents was genotyped using the Illumina PorcineSNP60 BeadChip, and 50,972 and 50,483 SNPs were available for F4ab and F4ac susceptibility, respectively, in the association analysis after quality control. In summary, 28 and 18 significant SNPs (p<0.05) were detected associated with F4ab and F4ac susceptibility respectively at genome-wide significance level. From these significant findings, two novel candidate genes, HEG1 and ITGB5, were firstly identified as the most promising genes underlying F4ab/F4ac susceptibility in swine according to their functions and positions. Our findings herein provide a novel evidence for unravelling genetic mechanism of diarrhoea risk in piglets.

Examining the practice of generalist expertise: a qualitative study identifying constraints and solutions  

PubMed Central

Objectives Provision of person-centred generalist care is a core component of quality primary care systems. The World Health Organisation believes that a lack of generalist primary care is contributing to inefficiency, ineffectiveness and inequity in healthcare. In UK primary care, General Practitioners (GPs) are the largest group of practising generalists. Yet GPs fulfil multiple roles and the pressures of delivering these roles along with wider contextual changes create real challenges to generalist practice. Our study aimed to explore GP perceptions of enablers and constraints for expert generalist care, in order to identify what is needed to ensure health systems are designed to support the generalist role. Design Qualitative study in General Practice. Setting UK primary care. Main outcome measures A qualitative study – interviews, surveys and focus groups with GPs and GP trainees. Data collection and analysis was informed by Normalisation Process Theory. Design and setting Qualitative study in General Practice. We conducted interviews, surveys and focus groups with GPs and GP trainees based mainly, but not exclusively, in the UK. Data collection and analysis were informed by Normalization Process Theory. Participants UK based GPs (interview and surveys); European GP trainees (focus groups). Results Our findings highlight key gaps in current training and service design which may limit development and implementation of expert generalist practice (EGP). These include the lack of a consistent and universal understanding of the distinct expertise of EGP, competing priorities inhibiting the delivery of EGP, lack of the consistent development of skills in interpretive practice and a lack of resources for monitoring EGP. Conclusions We describe four areas for change: Translating EGP, Priority setting for EGP, Trusting EGP and Identifying the impact of EGP. We outline proposals for work needed in each area to help enhance the expert generalist role.

Barcode Identifiers as a Practical Tool for Reliable Species Assignment of Medically Important Black Yeast Species  

PubMed Central

Herpotrichiellaceous black yeasts and relatives comprise severe pathogens flanked by nonpathogenic environmental siblings. Reliable identification by conventional methods is notoriously difficult. Molecular identification is hampered by the sequence variability in the internal transcribed spacer (ITS) domain caused by difficult-to-sequence homopolymeric regions and by poor taxonomic attribution of sequences deposited in GenBank. Here, we present a potential solution using short barcode identifiers (27 to 50 bp) based on ITS2 ribosomal DNA (rDNA), which allows unambiguous definition of species-specific fragments. Starting from proven sequences of ex-type and authentic strains, we were able to describe 103 identifiers. Multiple BLAST searches of these proposed barcode identifiers in GenBank revealed uniqueness for 100 taxonomic entities, whereas the three remaining identifiers each matched with two entities, but the species of these identifiers could easily be discriminated by differences in the remaining ITS regions. Using the proposed barcode identifiers, a 4.1-fold increase of 100% matches in GenBank was achieved in comparison to the classical approach using the complete ITS sequences. The proposed barcode identifiers will be made accessible for the diagnostic laboratory in a permanently updated online database, thereby providing a highly practical, reliable, and cost-effective tool for identification of clinically important black yeasts and relatives.

Practical strategies for identifying groundwater discharges into sediment and surface water with fiber optic temperature measurement.  

PubMed

Identifying or ruling out groundwater discharges into sediment and surface waters is often critical for evaluating impacts and for planning remedial actions. Information about subsurface structure and groundwater can be helpful, but imperfect information, heterogeneous materials, and the likelihood of preferential pathways make it difficult to locate seeps without direct seep monitoring. We present the practical application of a method that uses fiber optic temperature measurement to provide high-resolution, sensitive, and dynamic monitoring of seepage from sediments over large areas: distributed temperature sensing to identify groundwater discharge (DTSID). First, we introduce a stochastic Monte Carlo method for designing DTSID installation based on site characteristics and the required probability of detecting particular size seeps. We then present practical methods for analysing DTSID results to prioritize locations for further investigation used at three industrial locations. Summer conditions generally presented greater difficulty in the method due to stronger environmentally-driven temperature fluctuations and thermal stratification of surface water. Tidal fluctuations were shown to be helpful in seepage detection at some locations by creating a dynamic temperature pattern that likely reflects changing seepage with varying water levels. At locations with suitable conditions for the application of DTSID, it can provide unique information regarding likely seep locations, enhancing an integrated site investigation. PMID:24841752

Lessons learnt from promising practices in community engagement for the elimination of new HIV infections in children by 2015 and keeping their mothers alive: summary of a desk review  

PubMed Central

Introduction Through The Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping their Mothers Alive, leaders have called for broader action to strengthen the involvement of communities. The Global Plan aspires to reduce new HIV infections among children by 90 percent, and to reduce AIDS-related maternal mortality by half. This article summarizes the results of a review commissioned by UNAIDS to help inform stakeholders on promising practices in community engagement to accelerate progress towards these ambitious goals. Methods This research involved extensive literature review and key informant interviews. Community engagement was defined to include participation, mobilization and empowerment while excluding activities that involve communities solely as service recipients. A promising practice was defined as one for which there is documented evidence of its effectiveness in achieving intended results and some indication of replicability, scale up and/or sustainability. Results Promising practices that increased the supply of preventing mother-to-child transmission (PMTCT) services included extending community cadres, strengthening linkages with community- and faith-based organizations and civic participation in programme monitoring. Practices to improve demand for PMTCT included community-led social and behaviour change communication, peer support and participative approaches to generate local solutions. Practices to create an enabling environment included community activism and government leadership for greater involvement of communities. Committed leadership at all levels, facility, community, district and national, is crucial to success. Genuine community engagement requires a rights-based, capacity-building approach and sustained financial and technical investment. Participative formative research is a first step in building community capacity and helps to ensure programme relevance. Building on existing structures, rather than working in parallel to them, improves programme efficiency, effectiveness and sustainability. Monitoring, innovation and information sharing are critical to scale up. Conclusions Ten recommendations on community engagement are offered for ending vertical transmission and enhancing the health of mothers and families: (1) expand the frontline health workforce, (2) increase engagement with community- and faith-based organizations, (3) engage communities in programme monitoring and accountability, (4) promote community-driven social and behaviour change communication including grassroots campaigns and dialogues, (5) expand peer support, (6) empower communities to address programme barriers, (7) support community activism for political commitment, (8) share tools for community engagement, (9) develop better indicators for community involvement and (10) conduct cost analyses of various community engagement strategies. As programmes expand, care should be taken to support and not to undermine work that communities are already doing, but rather to actively identify and build on such efforts.

A Case Study with an Identified Bully: Policy and Practice Implications  

PubMed Central

Objective: Bullying is a serious public health problem that may include verbal or physical injury as well as social isolation or exclusion. As a result, research is needed to establish a database for policies and interventions designed to prevent bullying and its negative effects. This paper presents a case study that contributes to the literature by describing an intervention for bullies that has implications for practice and related policies regarding bullying. Methods: An individualized intervention for an identified bully was implemented using the Participatory Culture-Specific Intervention Model (PCSIM; Nastasi, Moore, & Varjas, 2004) with a seventh-grade middle school student. Ecological and culture-specific perspectives were used to develop and implement the intervention that included psychoeducational sessions with the student and consultation with the parent and school personnel. A mixed methods intervention design was used with the following informants: the target student, the mother of the student, a teacher and the school counselor. Qualitative data included semi-structured interviews with the parent, teacher and student, narrative classroom observations and evaluation/feedback forms filled out by the student and interventionist. Quantitative data included the following quantitative surveys (i.e., Child Self Report Post Traumatic Stress Reaction Index and the Behavior Assessment Scale for Children). Both qualitative and quantitative data were used to evaluate the acceptability, integrity and efficacy of this intervention. Results: The process of intervention design, implementation and evaluation are described through an illustrative case study. Qualitative and quantitative findings indicated a decrease in internalizing, externalizing and bullying behaviors as reported by the teacher and the mother, and a high degree of acceptability and treatment integrity as reported by multiple stakeholders. Conclusion: This case study makes important contributions by describing an intervention that is targeted to specific needs of the bully by designing culture specific interventions and working with the student’s unique environmental contexts. Contributions also are made by illustrating the use of mixed methods to document acceptability, integrity and efficacy of an intervention with documented positive effects in these areas. In addition, implications for policy and practice related to the treatment of students identified as bullies and future research needs are discussed.

Identifying Practical Solutions to Meet America's Fiber Needs: Proceedings from the Food & Fiber Summit  

PubMed Central

Fiber continues to be singled out as a nutrient of public health concern. Adequate intakes of fiber are associated with reduced risk for cardiovascular disease, cancer, diabetes, certain gastrointestinal disorders and obesity. Despite ongoing efforts to promote adequate fiber through increased vegetable, fruit and whole-grain intakes, average fiber consumption has remained flat at approximately half of the recommended daily amounts. Research indicates that consumers report increasingly attempting to add fiber-containing foods, but there is confusion around fiber in whole grains. The persistent and alarmingly low intakes of fiber prompted the “Food & Fiber Summit,” which assembled nutrition researchers, educators and communicators to explore fiber’s role in public health, current fiber consumption trends and consumer awareness data with the objective of generating opportunities and solutions to help close the fiber gap. The summit outcomes highlight the need to address consumer confusion and improve the understanding of sources of fiber, to recognize the benefits of various types of fibers and to influence future dietary guidance to provide prominence and clarity around meeting daily fiber recommendations through a variety of foods and fiber types. Potential opportunities to increase fiber intake were identified, with emphasis on meal occasions and food categories that offer practical solutions for closing the fiber gap.

Identifying Key Factors in Homeowner's Adoption of Water Quality Best Management Practices  

NASA Astrophysics Data System (ADS)

The recognition of the significance of the residential environment in contributing to non-point source (NPS) pollution and the inherently dispersed nature of NPS pollution itself that presents significant challenges to effective regulation has led to the creation and dissemination of best management practices (BMPs) that can reduce the impacts of NPS pollution (Environmental Protection Agency US, Protecting water quality from urban runoff, http://www.epa.gov/npdes/pubs/nps_urban-facts_final.pdf, 2003). However, very few studies have examined the factors that influence the adoption of BMPs by residential homeowners, despite the fact that residential environments have been identified as one of the most significant contributors to NPS pollution. Given this need, the purpose of this project was to explore how demographic and knowledge-based factors predict adoption of residential BMPs in an urbanizing watershed in Northern Illinois using statistical analyses of survey data collected as part of a watershed planning process. The findings indicate that broad knowledge of BMPs is the strongest predictor of use for a specific BMP. Knowledge of BMPs is strongly correlated with their use, which reinforces the need for educational programs, even among those assumed to be knowledgeable about BMPs.

Arsenic-induced skin conditions identified in southwest dermatology practices: an epidemiologic tool?  

PubMed

Populations living in the Southwest United States are more likely to be exposed to elevated drinking water arsenic levels compared to other areas of the country. Skin changes, including hyperpigmentation and generalized hyperkeratosis, are the most common signs of chronic arsenic ingestion from drinking water. The purpose of this study was to determine the feasibility of using dermatology practices in New Mexico, Arizona, and western Texas as a surveillance system for arsenical skin disorders related to drinking water. Postcard questionnaires were mailed to practicing dermatologists. The number of cases of arsenical hyperpigmentation/keratoses seen by these dermatologists during the past 10 years and the past year were estimated. Of 240 dermatologists who were mailed questionnaires, 37 reported seeing 237 patients with arsenical hyperpigmentation/keratoses in the past 10 years and 35 patients in the past year. Since approximately one-eighth of dermatologists practicing in the Southwest saw at least one patient with arsenical hyperpigmentation/keratoses during one year, it appears feasible to complete a population-based study of these conditions.

Biomarkers identified with time-lapse imaging: discovery, validation, and practical application.  

PubMed

"Time-lapse markers," which are defined by time-lapse imaging and correlated with clinical outcomes, may provide embryologists with new opportunities for improving embryo selection. This article provides an overview of noninvasive biomarkers defined by time-lapse imaging studies. In addition to comprehensively reviewing the discovery of each time-lapse marker, it focuses on the criteria necessary for their successful integration into clinical practice, including [1] statistical and biological significance, [2] validation through prospective clinical studies, and [3] development of reliable technology to measure and quantify the time-lapse marker. Because manual analysis of time-lapse images is labor intensive and limits the practical use of the image data in the clinic, automated image analysis software platforms may contribute substantially to improvements in embryo selection accuracy. Ultimately, time-lapse markers that are based on a foundation of basic research, validated through prospective clinical studies, and enabled by a reliable quantification technology may improve IVF success rates, encourage broader adoption of single-embryo transfer, and reduce the risks associated with multiple gestation pregnancies.

Practical method to identify orbital anomaly as spacecraft breakup in the geostationary region  

NASA Astrophysics Data System (ADS)

Identifying spacecraft breakup events is an essential issue for better understanding of the current orbital debris environment. This paper proposes an observation planning approach to identify an orbital anomaly, which appears as a significant discontinuity in archived orbital history, as a spacecraft breakup. The proposed approach is applicable to orbital anomalies in the geostationary region. The proposed approach selects a spacecraft that experienced an orbital anomaly, and then predicts trajectories of possible fragments of the spacecraft at an observation epoch. This paper theoretically demonstrates that observation planning for the possible fragments can be conducted. To do this, long-term behaviors of the possible fragments are evaluated. It is concluded that intersections of their trajectories will converge into several corresponding regions in the celestial sphere even if the breakup epoch is not specified and it has uncertainty of the order of several weeks.

Pharmaceutical Care Plan Examinations to Identify Students at Risk for Poor Performance in Advanced Pharmacy Practice Experiences  

PubMed Central

Objectives To evaluate early predictors of advanced pharmacy practice experience (APPE) performance using either timed pharmaceutical care plan (TPCP) reports of 4 case histories or traditional lecture-based pharmacotherapy course examinations. Methods Statistical process control (SPC) methods were used to identify a group of third-year pharmacy students “at risk” for poor APPE performance (defined as an APPE grade point average of < 3.0). Examination scores from an integrated lecture-based pharmacotherapy sequence were used for comparison. Results TPCP scores but not lecture-based examination scores successfully identified 6 of 10 students who ultimately performed poorly in their APPEs. Conclusion Adaptation of SPC methods to assess student performance during problem-based learning (PBL) case reports is a useful technique for identifying students “at risk” for poor APPE performance.

Persistent Identifiers in the Publication and Citation of Scientific Data - Theory and Practice  

NASA Astrophysics Data System (ADS)

In the last decade data driven research has become a third pillar of scientific work alongside with theoretical reasoning and experiment. Greatly increased computing power and storage, together with web services and other electronic resources have facilitated a quantum leap in new research based on the analysis of great amounts of data. However, traditional scientific communication only slowly changes to new media other than an emulation of paper. This leaves many data inaccessible and, in the long run exposes valuable data to the risk of loss. To improve access to data and to create incentives for scientists to make their data accessible, a group of German data centres initiated the project "Publication and Citation of Scientific Data" (STD-DOI) which was funded by the German Science Foundation DFG for the periods 2003-2005 and 2006-2008. In this project the German National Library for Science and Technology (TIB Hannover), together with the German Research Centre for Geoscience (GFZ Potsdam), Alfred Wegener Institute for Polar and Marine Research (AWI) Bremerhaven, University of Bremen, the Max Planck Institute for Meteorology in Hamburg, and the DLR German Remote Sensing Data Center set up the first system to assign DOIs to data sets and for their publication. A prerequisite for data to be made available is a proper citation. This means that all fields mandatory for a bibliographic citation are included. In addition, a mechanism is needed that ensures that the location of the referenced data on the internet can be resolved at any time. In the past, this was a problematic issue because URLs are short-lived, many becoming invalid after only a few months. Data publication on the internet therefore needs a system of reliable pointers to a web publication to make these publications citeable. To achieve this persistence of identifiers for their conventional publications many scientific publishers use Digital Object Identifiers (DOI). The identifier is resolved through the handle system to the valid location (URL) where the dataset can be found. This approach meets one of the prerequisites for citeability of scientific data published online. In addition, the valid bibliographic citation can be included in the catalogues of German National Library of Science and Technology (TIB). The data publications themselves are held at discipline specific data centres, for instance ICSU World Data Centers. The data providers take on the role of publication agents and are responsible for the long-term availability of the data. The discipline specific publication agents are also responsible for the quality of the published data. Syntactic and semantic quality checks are used to secure data quality. Data may come as data supplements to scientific papers, or as time series from environmental monitoring systems, or as novel form of publication in a data journal. The latter requires a peer-review process, analogous to conventional science publications.

Enhance patient safety by identifying and minimizing risk exposures affecting nurse practitioner practice.  

PubMed

A study analyzing closed professional liability claims against nurse practitioners over a 5-year period was completed by CNA and Nurses Service Organization (NSO). Of 200 closed claims, the average total incurred payment per claim was $285 645. The study identifies current liability patterns and trends and provides risk-control recommendations to enhance patient safety and minimize liability exposure. Study results indicate that while the number of nurse practitioner claims have been relatively stable over the past 5 years (2007-2011), the number of claims resulting in very severe indemnity payment have increased 19% since 2009. The data also show that many claims develop from a failure involving core competencies, such as treatment and care management, and medication prescribing. Allegations related to failure to diagnose and delay in making a correct diagnosis were found most frequently. The claims demonstrate that nurse practitioners are responsible for obtaining and documenting the results of appropriate tests, consultations, and overall need for medical intervention to meet the patient's medical needs.

Laboratory test ordering and results management systems: a qualitative study of safety risks identified by administrators in general practice  

PubMed Central

Objective To explore experiences and perceptions of frontline administrators involved in the systems-based management of laboratory test ordering and results handling in general medical practice. Design Qualitative using focus group interviews. Setting West of Scotland general medical practices in three National Health Service (NHS) territorial board areas. Participants Convenience samples of administrators (receptionists, healthcare assistants and phlebotomists). Methods Transcript data were subjected to content analysis. Results A total of 40 administrative staff were recruited. Four key themes emerged: (1) system variations and weaknesses (eg, lack of a tracking process is a known risk that needs to be addressed). (2) Doctor to administrator communication (eg, unclear information can lead to emotional impacts and additional workload). (3) Informing patients of test results (eg, levels of anxiety and uncertainty are experienced by administrators influenced by experience and test result outcome) and (4) patient follow-up and confidentiality (eg, maintaining confidentiality in a busy reception area can be challenging). The key findings were explained in terms of sociotechnical systems theory. Conclusions The study further confirms the safety-related problems associated with results handling systems and adds to our knowledge of the communication and psychosocial issues that can affect the health and well-being of staff and patients alike. However, opportunities exist for practices to identify barriers to safe care, and plan and implement system improvements to accommodate or mitigate the potential for human error in this complex area.

Applying psychological theory to evidence-based clinical practice: identifying factors predictive of taking intra-oral radiographs.  

PubMed

This study applies psychological theory to the implementation of evidence-based clinical practice. The first objective was to see if variables from psychological frameworks (developed to understand, predict and influence behaviour) could predict an evidence-based clinical behaviour. The second objective was to develop a scientific rationale to design or choose an implementation intervention. Variables from the Theory of Planned Behaviour, Social Cognitive Theory, Self-Regulation Model, Operant Conditioning, Implementation Intentions and the Precaution Adoption Process were measured, with data collection by postal survey. The primary outcome was the number of intra-oral radiographs taken per course of treatment collected from a central fee claims database. Participants were 214 Scottish General Dental Practitioners. At the theory level, the Theory of Planned Behaviour explained 13% variance in the number of radiographs taken, Social Cognitive Theory explained 7%, Operant Conditioning explained 8%, Implementation Intentions explained 11%. Self-Regulation and Stage Theory did not predict significant variance in radiographs taken. Perceived behavioural control, action planning and risk perception explained 16% of the variance in number of radiographs taken. Knowledge did not predict the number of radiographs taken. The results suggest an intervention targeting predictive psychological variables could increase the implementation of this evidence-based practice, while influencing knowledge is unlikely to do so. Measures which predicted number of radiographs taken also predicted intention to take radiographs, and intention accounted for significant variance in behaviour (adjusted R(2)=5%: F(1,166)=10.28, p<.01), suggesting intention may be a possible proxy for behavioural data when testing an intervention prior to a service-level trial. Since psychological frameworks incorporate methodologies to measure and change component variables, taking a theory-based approach enabled the creation of a methodology that can be replicated for identifying factors predictive of clinical behaviour and for the design and choice of interventions to modify practice as new evidence emerges.

Developing clinical practice guidelines: target audiences, identifying topics for guidelines, guideline group composition and functioning and conflicts of interest  

PubMed Central

Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this first paper we discuss: the target audience(s) for guidelines and their use of guidelines; identifying topics for guidelines; guideline group composition (including consumer involvement) and the processes by which guideline groups function and the important procedural issue of managing conflicts of interest in guideline development.

Off-label prescriptions: how to identify them, frame them, announce them and monitor them in practice?  

PubMed

Following the Mediator crisis and the passage of the Health and Safety Law of December 2011, off-label prescriptions are a real concern shared by all those involved in healthcare system. Off-label, in the strictest sense of the term, is defined as all prescriptions that do not correspond to the summary of product characteristics (SPC), particularly those that fail to comply with the indications and dosage regimens defined by the marketing authorization (MA) for clear safety reasons. There are various rasons for off-label prescriptions, both conscious and unconscious. They are intended to respond to unmet medical needs, the needs of poorly studied populations or not studied at all in trials, but in relation to whom it is reasonable to extrapolate that MA would be given (common-sense prescriptions) and, additionally, to urgent public health needs (such as baclofen, pregnant women, and HIV drugs). All these prescriptions would deserve to be studied for a potential MA. However, there are off-label prescriptions that need to be restricted or even penalized in the case of compassionate prescriptions or unjustified prescriptions or prescriptions not based on any scientific grounds. Off-label prescriptions are not easy to track down because if the prescriber has to write "off-label" on his prescription, then clearly, in practice, he will only do so in exceptional cases. Neither the pharmacists who dispense the drug nor the Social Security that reimburses it, have access to the diagnosis (or targeted indication). Thus, in order to identify the off-label prescription, we must be able to cross reference the available databases (such as pharmacovigilance database, medicalized information system program [programme de médicalisation des systèmes d'information, PMSI], hospital drug formularies, general sample of beneficiaries [échantillon généraliste de bénéficiaires, EGB] or national inter-regional Health Insurance Information System [système national d'informations inter-régions d'Assurance maladie, SNIIRAM], sales data, and data from market surveys). The shared computerized patient file may resolve this problem. The temporary use recommendation (TUR) proposed by the Drug Safety Law will only partially deal with this problem for recently marketed molecules. This temporary and exceptional mechanism will authorize a recognized off-label prescription, which may be reimbursed and monitored for 3 years. These TURs will only concern a small portion of "off-label" drugs having yet a positive risk/benefit ratio (conditional MA) but this is far from matching with majority of off-label prescriptions. As such, and in order to improve the use of drugs, it is important to propose a control system for all "off-label" prescriptions with a dedicated committee: the "off-label" committee which would determine the frame of the "off-label" prescriptions.

Changing policy and practice in the child welfare system through collaborative efforts to identify and respond effectively to family violence.  

PubMed

The Greenbook provides a roadmap for child welfare agencies to collaborate and provide effective responses to families who are experiencing co-occurring child maltreatment and domestic violence. A multisite developmental evaluation was conducted of six demonstration sites that received federal funding to implement Greenbook recommendations for child welfare agencies. Surveys of child welfare caseworkers show significant changes in several areas of agency policy and practice, including regular domestic violence training, written guidelines for reporting domestic violence, and working closely and sharing resources with local domestic violence service providers. Case file reviews show significant increases in the level of active screening for domestic violence, although this increase peaks at the midpoint of the initiative. These findings, coupled with on-site interview data, point to the importance of coordinating system change activities in child welfare agencies with a number of other collaborative activities.

Applying psychological theories to evidence-based clinical practice: identifying factors predictive of lumbar spine x-ray for low back pain in UK primary care practice  

PubMed Central

Background Psychological models predict behaviour in a wide range of settings. The aim of this study was to explore the usefulness of a range of psychological models to predict the health professional behaviour 'referral for lumbar spine x-ray in patients presenting with low back pain' by UK primary care physicians. Methods Psychological measures were collected by postal questionnaire survey from a random sample of primary care physicians in Scotland and north England. The outcome measures were clinical behaviour (referral rates for lumbar spine x-rays), behavioural simulation (lumbar spine x-ray referral decisions based upon scenarios), and behavioural intention (general intention to refer for lumbar spine x-rays in patients with low back pain). Explanatory variables were the constructs within the Theory of Planned Behaviour (TPB), Social Cognitive Theory (SCT), Common Sense Self-Regulation Model (CS-SRM), Operant Learning Theory (OLT), Implementation Intention (II), Weinstein's Stage Model termed the Precaution Adoption Process (PAP), and knowledge. For each of the outcome measures, a generalised linear model was used to examine the predictive value of each theory individually. Linear regression was used for the intention and simulation outcomes, and negative binomial regression was used for the behaviour outcome. Following this 'theory level' analysis, a 'cross-theoretical construct' analysis was conducted to investigate the combined predictive value of all individual constructs across theories. Results Constructs from TPB, SCT, CS-SRM, and OLT predicted behaviour; however, the theoretical models did not fit the data well. When predicting behavioural simulation, the proportion of variance explained by individual theories was TPB 11.6%, SCT 12.1%, OLT 8.1%, and II 1.5% of the variance, and in the cross-theory analysis constructs from TPB, CS-SRM and II explained 16.5% of the variance in simulated behaviours. When predicting intention, the proportion of variance explained by individual theories was TPB 25.0%, SCT 21.5%, CS-SRM 11.3%, OLT 26.3%, PAP 2.6%, and knowledge 2.3%, and in the cross-theory analysis constructs from TPB, SCT, CS-SRM, and OLT explained 33.5% variance in intention. Together these results suggest that physicians' beliefs about consequences and beliefs about capabilities are likely determinants of lumbar spine x-ray referrals. Conclusions The study provides evidence that taking a theory-based approach enables the creation of a replicable methodology for identifying factors that predict clinical behaviour. However, a number of conceptual and methodological challenges remain.

Altered standards of care during an influenza pandemic: identifying ethical, legal, and practical principles to guide decision making.  

PubMed

Although widespread support favors prospective planning for altered standards of care during mass casualty events, the literature includes few, if any, accounts of groups that have formally addressed the overarching policy considerations at the state level. We describe the planning process undertaken by public health officials in the Commonwealth of Massachusetts, along with community and academic partners, to explore the issues surrounding altered standards of care in the event of pandemic influenza. Throughout 2006, the Massachusetts Department of Public Health and the Harvard School of Public Health Center for Public Health Preparedness jointly convened a working group comprising ethicists, lawyers, clinicians, and local and state public health officials to consider issues such as allocation of antiviral medications, prioritization of critical care, and state seizure of private assets. Community stakeholders were also engaged in the process through facilitated discussion of case scenarios focused on these and other issues. The objective of this initiative was to establish a framework and some fundamental principles that would subsequently guide the process of establishing specific altered standards of care protocols. The group collectively identified 4 goals and 7 principles to guide the equitable allocation of limited resources and establishment of altered standards of care protocols. Reviewing and analyzing this process to date may serve as a resource for other states. PMID:19755912

Performance Scores in General Practice: A Comparison between the Clinical versus Medication-Based Approach to Identify Target Populations  

PubMed Central

Context From one country to another, the pay-for-performance mechanisms differ on one significant point: the identification of target populations, that is, populations which serve as a basis for calculating the indicators. The aim of this study was to compare clinical versus medication-based identification of populations of patients with diabetes and hypertension over the age of 50 (for men) or 60 (for women), and any consequences this may have on the calculation of P4P indicators. Methods A comparative, retrospective, observational study was carried out with clinical and prescription data from a panel of general practitioners (GPs), the Observatory of General Medicine (OMG) for the year 2007. Two indicators regarding the prescription for statins and aspirin in these populations were calculated. Results We analyzed data from 21.690 patients collected by 61 GPs via electronic medical files. Following the clinical-based approach, 2.278 patients were diabetic, 8,271 had hypertension and 1.539 had both against respectively 1.730, 8.511 and 1.304 following the medication-based approach (% agreement?=?96%, kappa?=?0.69). The main reasons for these differences were: forgetting to code the morbidities in the clinical approach, not taking into account the population of patients who were given life style and diet rules only or taking into account patients for whom morbidities other than hypertension could justify the use of antihypertensive drugs in the medication-based approach. The mean (confidence interval) per doctor was 33.7% (31.5–35.9) for statin indicator and 38.4% (35.4–41.4) for aspirin indicator when the target populations were identified on the basis of clinical criteria whereas they were 37.9% (36.3–39.4) and 43.8% (41.4–46.3) on the basis of treatment criteria. Conclusion The two approaches yield very “similar” scores but these scores cover different realities and offer food for thought on the possible usage of these indicators in the framework of P4P programmes.

Applying psychological theories to evidence-based clinical practice: identifying factors predictive of placing preventive fissure sealants  

PubMed Central

Background Psychological models are used to understand and predict behaviour in a wide range of settings, but have not been consistently applied to health professional behaviours, and the contribution of differing theories is not clear. This study explored the usefulness of a range of models to predict an evidence-based behaviour -- the placing of fissure sealants. Methods Measures were collected by postal questionnaire from a random sample of general dental practitioners (GDPs) in Scotland. Outcomes were behavioural simulation (scenario decision-making), and behavioural intention. Predictor variables were from the Theory of Planned Behaviour (TPB), Social Cognitive Theory (SCT), Common Sense Self-regulation Model (CS-SRM), Operant Learning Theory (OLT), Implementation Intention (II), Stage Model, and knowledge (a non-theoretical construct). Multiple regression analysis was used to examine the predictive value of each theoretical model individually. Significant constructs from all theories were then entered into a 'cross theory' stepwise regression analysis to investigate their combined predictive value Results Behavioural simulation - theory level variance explained was: TPB 31%; SCT 29%; II 7%; OLT 30%. Neither CS-SRM nor stage explained significant variance. In the cross theory analysis, habit (OLT), timeline acute (CS-SRM), and outcome expectancy (SCT) entered the equation, together explaining 38% of the variance. Behavioural intention - theory level variance explained was: TPB 30%; SCT 24%; OLT 58%, CS-SRM 27%. GDPs in the action stage had significantly higher intention to place fissure sealants. In the cross theory analysis, habit (OLT) and attitude (TPB) entered the equation, together explaining 68% of the variance in intention. Summary The study provides evidence that psychological models can be useful in understanding and predicting clinical behaviour. Taking a theory-based approach enables the creation of a replicable methodology for identifying factors that may predict clinical behaviour and so provide possible targets for knowledge translation interventions. Results suggest that more evidence-based behaviour may be achieved by influencing beliefs about the positive outcomes of placing fissure sealants and building a habit of placing them as part of patient management. However a number of conceptual and methodological challenges remain.

Delivering reproductive health promises.  

PubMed

This article briefly covers some issues involved in implementing the reproductive health agenda of the Fourth World Conference on Women, held in Beijing in 1995. A more detailed discussion is presented by the author in a Family Health International Working Paper (No. WP95-01). The reproductive health goals of the Beijing's women's conference were a ratification of the Plan of Action from the 1994 International Conference on Population and Development, Cairo. Women's empowerment is viewed as possible with a comprehensive, client-centered view of reproductive health services integrated with family planning. There remain many policy and service delivery challenges to integrated programs. The two main objectives of integrated services are to better meet client's needs and to improve efficiency and effectiveness of these services. There was some conference agreement on 16 broad groups and 76 specific services, which would be included in integrated programs. A service structure alone did not assure integrated services. The presence of established vertical programs and weak administrative capacity were obstacles, which had a more marked impact on integrated programs. Service delivery was viewed as enhanced by effective donor collaboration. A unified set of priorities between different donors must be agreed upon. Donors must also reach agreement on resource sharing, assumptions of joint responsibility for success and failure, and balancing of local priorities with agency priorities. The National Policy Development process must include a range of constituent groups, such as women's groups, policy makers, grassroots organizers, service providers, and client representatives. Service gaps could be identified by operations research efforts. A greater health impact could be achieved by programs with limited scope but clearly identified priorities than overextended comprehensive programs. Logistics and services delivery systems could adjust better when service components were phased in. Vertical government ministry organization, even with consistent national policy, was an obstacle to integration. Integration is costly, and funding needs must be secured. Implementation of integrated programs could be enhanced by use of the lessons learned already. PMID:12346900

Therapeutic promise and principles  

PubMed Central

For a number of disease entities, oxidative stress becomes a significant factor in the etiology and progression of cell dysfunction and injury. Therapeutic strategies that can identify novel signal transduction pathways to ameliorate the toxic effects of oxidative stress may lead to new avenues of treatment for a spectrum of disorders that include diabetes, Alzheimer's disease, Parkinson's disease and immune system dysfunction. In this respect, metabotropic glutamate receptors (mGluRs) may offer exciting prospects for several disorders since these receptors can limit or prevent apoptotic cell injury as well as impact upon cellular development and function. Yet the role of mGluRs is complex in nature and may require specific mGluR modulation for a particular disease entity to maximize clinical efficacy and limit potential disability. Here we discuss the potential clinical translation of mGluRs and highlight the role of novel signal transduction pathways in the metabotropic glutamate system that may be vital for the clinical utility of mGluRs.

A cross-sectional study identifying the pattern of factors related to psychological intimate partner violence exposure in Slovenian family practice attendees: what hurt them the most  

PubMed Central

Background Intimate partner violence (IPV) is yet to be fully acknowledged as a public health problem in Slovenia. This study aimed to explore the health and other patient characteristics associated with psychological IPV exposure and gender-related specificity in family clinic attendees. Methods In a multi-centre cross-sectional study, 960 family practice attendees aged 18 years and above were recruited. In 689 interviews with currently- or previously-partnered patients, the short form of A Domestic Violence Exposure Questionnaire and additional questions about behavioural patterns of exposure to psychological abuse in the past year were given. General practitioners (GPs) reviewed the medical charts of 470 patients who met the IPV exposure criteria. The Domestic Violence Exposure Medical Chart Check List was used, collecting data on the patients’ lives and physical, sexual and reproductive, and psychological health status, as well as sick leave, hospitalisation, visits to family practices and referrals to other clinical specialists in the past year. In multivariate logistic regression modelling the factors associated with past year psychological IPV exposure were identified, with P?

AMLCD cockpit: promise and payoffs  

NASA Astrophysics Data System (ADS)

The active matrix liquid crystal display (AMLCD) has become the preferred flight instrument technology in avionics multifunction display applications. Current bubble canopy fighter cockpit applications involve sizes up to 7.8 X 7.8 in. active display. Dual use avionics versions of AMLCD technology are now as large as 6.7 X 6.7 in. active display area in the ARINC D sized color multifunction display (MFD). This is the standard instrument in all new Boeing transport aircraft and is being retrofitted into the C-17A. A special design of the ARINC D instrument is used in the Space Shuttle cockpit upgrade. Larger sizes of AMLCD were desired when decisions were made in the early 1990s for the F-22. Commercial AMLCD technology has now produced monitors at 1280 X 1024 resolution (1.3 megapixels) in sizes of 16 to 21 in. diagonal. Each of these larger AMLCDs has more information carrying capacity than the entire F-22A cockpit instrument panel shipset, comprising six separate smaller AMLCDs (1.2 megapixels total). The larger AMLCDs are being integrated into airborne mission crewstations for use in dim ambient lighting conditions. It is now time to identify and address the technology challenges of upgrading these larger AMLCDs for sunlight readable application and of developing concepts for their integration into advanced bubble canopy fighter cockpits. The overall goals are to significantly increase the informational carrying capacity to bring both sensor and information fusion into the cockpit and, thereby, to enable a significant increase in warfighter situational awareness and effectiveness. A research cockpit was built using specialized versions of the IBM 16.1 in and two smaller 10 in. AMLCDs to examine human factors and display design issues associated with these next-generation AMLCD cockpit displays. This cockpit was later upgraded to allow greater reconfigurability and flexibility in the display hardware used to conduct part- task mission simulations. The objective optical characterization of the AMLCDs used in this simulator and the cockpit design are described. Display formats under consideration for test in this cockpit are described together with some of the basic human factors engineering issues involved. Studies conducted in this cockpit will be part of an ongoing joint effort of the hardware-focused aerospace displays team and the pilot-focused human factors team in the Air Force Research Laboratory's Crew System Interface Division. The objective of these studies is to ascertain the payoffs of the large AMLCD promise in combat cockpits.

Identifying characteristics associated with performing recommended practices in maternal and newborn care among health facilities in Rwanda: a cross-sectional study  

PubMed Central

Background Although rates of maternal and neonatal mortality have decreased in many countries over the last two decades, they remain unacceptably high, particularly in sub-Saharan Africa. Nevertheless, we know little about the quality of facility-based maternal and newborn care in low-income countries and little about the association between quality of care and health worker training, supervision, and incentives in these settings. We therefore sought to examine the quality of facility-based maternal and newborn health care by describing the implementation of recommended practices for maternal and newborn care among health care facilities. We also aimed to determine whether increased training, supervision, and incentives for health workers were associated with implementing these recommended practices. We chose to study these aims in the Republic of Rwanda, where rates of maternal and newborn mortality are high and where substantial attention is currently focused on strengthening health workforce capacity and quality. Methods We used data from the 2007 Rwanda Service Provision Assessment. Using observations from 455 facilities and interviews from 1357 providers, we generated descriptive statistics to describe the use of recommended practices and frequencies of provider training, supervision, and incentives in the areas of antenatal, delivery, and newborn care. We then constructed multivariable regression models to examine the associations between using recommended practices and health provider training, supervision, and incentives. Results Use of recommended practices varied widely, and very few facilities performed all recommended practices. Furthermore, in most areas of care, less than 25% of providers reported having had any pre-service or in-service training in the last 3?years. Contrary to our hypotheses, we found no evidence that training, supervision, or incentives were consistently associated with using recommended practices. Conclusion Our findings highlight the need to improve facility-based maternal and newborn care in Rwanda and suggest that current approaches to workforce training, supervision, and incentives may not be adequate for improving these critical practices.

Realizing the promise of cancer predisposition genes.  

PubMed

Genes in which germline mutations confer highly or moderately increased risks of cancer are called cancer predisposition genes. More than 100 of these genes have been identified, providing important scientific insights in many areas, particularly the mechanisms of cancer causation. Moreover, clinical utilization of cancer predisposition genes has had a substantial impact on diagnosis, optimized management and prevention of cancer. The recent transformative advances in DNA sequencing hold the promise of many more cancer predisposition gene discoveries, and greater and broader clinical applications. However, there is also considerable potential for incorrect inferences and inappropriate clinical applications. Realizing the promise of cancer predisposition genes for science and medicine will thus require careful navigation. PMID:24429628

Feasibility evaluation of a stepped procedure to identify community-dwelling frail older people in general practice. A mixed methods study.  

PubMed

Abstract Background: Implementation of frailty identification methods in general practice has hardly been established. To achieve successful implementation, general practitioners (GPs) should be provided with an identification method that suits their needs. EASYcare-TOS is a new frailty identification method that uses a stepped approach and is specifically developed for use in general practice. The first step consists of the GP's frailty judgment based on his prior information on the patient. If the judgment is 'uncertain' or 'frail,' additional data are collected by a primary care nurse (PCN). The frailty decision is based on clinical reasoning by the GP, without applying predefined cut-offs in a numerical score. Objective: To evaluate the acceptability of EASYcare-TOS in daily general practice. Methods A mixed-methods study was conducted. Questionnaires were sent to all professionals (n = 25) who participated in the EASYcare-TOS validation study. Subsequently, semi-structured interviews with primary care professionals (n = 12) and patients (n = 9) were conducted. Results: Time investment was generally perceived as acceptable. Twenty-two professionals (88%) found a two-step model (very) useful in the identification instrument. Seventeen professionals (68%) valued making the final frailty decision by their own clinical reasoning. Patients appreciated the broad assessment and the advice given based on the assessment. According to 24 (96%) professionals, EASYcare-TOS improved the quality of patient care. GPs stated that implementation will ask for reconsidering allocation of tasks in general practices and adequate reimbursement. Conclusion: EASYcare-TOS is a new identification method that fits the needs of primary care professionals to a large extent and is acceptable in daily practice. PMID:24224607

The (non)comparability of the correlation effect size across different measurement procedures: a challenge to meta-analysis as a tool for identifying "evidence based practices".  

PubMed

Meta-analysis is becoming a principal tool for research synthesis and for the identification and justification of evidence based practices. A fundamental assumption in meta-analysis is that effect sizes based upon different measures are comparable. Recent work has challenged this assumption in the case of the standardized mean difference. In this article it is shown that population universe (true) score level correlation effect sizes, for the relationship between two constructs A and B, based upon different measures will be comparable only if construct validity invariance holds across the measures used to make inferences to A and the measures used to make inferences to B. The results of a simulation study are also reported which show that the results of a meta-analysis may be significantly and adversely affected by violations of construct validity invariance. Finally, it is concluded that the theoretical results obtained in this article, and the results of the simulation study, combine to suggest that the role of meta-analysis in the synthesis of social work research, and in the identification of evidence based practices, be de-emphasized until important questions about the sensitivity of meta-analysis to violations of construct validity invariance are answered.

Cultural Neuroscience: Progress and Promise  

PubMed Central

The nature and origin of human diversity has been a source of intellectual curiosity since the beginning of human history. Contemporary advances in cultural and biological sciences provide unique opportunities for the emerging field of cultural neuroscience. Research in cultural neuroscience examines how cultural and genetic diversity shape the human mind, brain and behavior across multiple time scales: situation, ontogeny and phylogeny. Recent progress in cultural neuroscience provides novel theoretical frameworks for understanding the complex interaction of environmental, cultural and genetic factors in the production of adaptive human behavior. Here, we provide a brief history of cultural neuroscience, theoretical and methodological advances, as well as empirical evidence of the promise of and progress in the field. Implications of this research for population health disparities and public policy are discussed.

Present but not accounted for: exploring the sexual risk practices and intervention needs of nonheterosexually identified women in a prevention program for women with HIV/AIDS.  

PubMed

Nonheterosexually identified (NHI) women may be present, but not accounted for, in HIV and sexually transmitted infection (STI) prevention interventions. This study used quantitative and qualitative methods to examine the sexual risk behaviors and intervention needs of NHI women in Protect and Respect, a safer sex intervention for HIV-positive women. Study participants (n=32) were predominantly Black, low income, and between 28 and 51 years old. Although NHI participants were more likely than heterosexual participants (p < .05) to report obtaining their income from sex work, hustling, or selling drugs; and having a higher median number of male sex partners, qualitative analyses revealed that the intervention often neglected NHI women's experiences and unique safer sex needs. Heterosexist HIV and STI prevention programs may hinder NHI women's ability to protect themselves and their partners from reinfection and infection respectively. We discuss the implications of our research for future HIV/AIDS and STI research, services and interventions for NHI women. PMID:19042909

A comparison between the efficiency of the Xpert MTB/RIF assay and nested PCR in identifying Mycobacterium tuberculosis during routine clinical practice  

PubMed Central

Objectives Polymerase chain reaction (PCR) for the detection of Mycobacterium tuberculosis (MTB) is more sensitive, specific, and rapid than the conventional methods of acid-fast bacilli (AFB) smear and culture. The aim of this study was to determine if the Xpert MTB/rifampicin (RIF) assay had additional advantages over nested PCR for the detection of MTB in a geographical area with intermediate tuberculosis (TB) incidence. Methods Between February and December 2013, the Xpert MTB/RIF assay and MTB nested PCR, as well as AFB smear and culture, were simultaneously performed on 198 clinical samples (160 pulmonary and 38 non-pulmonary specimens) collected from 171 patients hospitalized at Hallym University Medical Center for possible TB. The accuracy of the diagnosis of MTB culture-positive TB and the turnaround time of reporting laboratory results were calculated and compared. Rifampin resistance by the Xpert MTB/RIF assay was reviewed with that of conventional drug susceptibility testing (DST). Results The sensitivity, specificity, and positive and negative predictive values of the Xpert MTB/RIF assay and MTB nested PCR for diagnosis of MTB culture-positive pulmonary TB were 86.1% vs. 69.4% (P=0.1563), 97.8% vs. 94.1% (P=0.2173), 91.2% vs. 75.8% (P=0.1695), and 96.4% vs. 92.0% (P=0.2032), respectively. The median turnaround times of the Xpert MTB/RIF assay and MTB nested PCR were 0 [0-4] days and 4 [1-11] days, respectively (P<0.001). Two cases of rifampin resistance, as determined by the Xpert MTB/RIF assay, were found to be multi-drug resistant (MDR) pulmonary TB by DST. Conclusions The Xpert MTB/RIF assay seemed to be sensitive, specific, and comparable to nested PCR for identifying MTB among clinically suspected TB patients, and the assay can be valuable in giving a timely identification of resistance to rifampin.

Multiple sclerosis: Prospects and promise.  

PubMed

We have entered a golden era in multiple sclerosis (MS) research. Two decades ago, our understanding of the disease was largely descriptive and there were no approved therapies to modify the natural history of MS. Today, delineation of immune pathways relevant to MS have been clarified; a comprehensive map of genes that influence risk compiled; clues to environmental triggers identified; noninvasive in vivo monitoring of the MS disease process has been revolutionized by high-field MRI; and many effective therapies for the early, relapsing, component of MS now exist. However, major challenges remain. We still have no useful treatment for progressive MS (the holy grail of MS research), no means to repair injured axons or protect neurons, and extremely limited evidence to guide treatment decisions. Recent advances have set in place a foundation for development of increasingly selective immunotherapy for patients; application of genetic and genomic discoveries to improve therapeutic options; development of remyelination or neuroprotection therapies for progressive MS; and integrating clinical, imaging and genomic data for personalized medicine. MS has now advanced from the backwaters of autoimmune disease research to the front-line, and definitive answers, including cures, are now realistic goals for the next decade. Many of the breakthrough discoveries in MS have also resulted from meaningful interactions across disciplines, and especially from translational and basic scientists working closely with clinicians, highlighting that the clinical value of discoveries are most often revealed when ideas developed in the laboratory are tested at the bedside.

Cancer and Inflammation: Promise for Biological Therapy  

PubMed Central

Cancers often arise as the end stage of inflammation in adults, but not in children. As such there is a complex interplay between host immune cells during neoplastic development, with both an ability to promote cancer as well as limit or eliminate it, most often complicit with the host. In humans, defining inflammation and the presence of inflammatory cells within or surrounding the tumor is a critical aspect of modern pathology. Groups defining staging for neoplasms are strongly encouraged to assess and incorporate measures of the presence of apoptosis, autophagy, and necrosis as well as the nature and quality of the immune infiltrate. Both environmental as well as genetic factors enhance the risk of cigarette smoking, H. pylori, hepatitis B/C, human papilloma virus, solar irradiation, asbestos, pancreatitis, or other causes of chronic inflammation. Identifying suitable genetic polymorphisms in cytokines, cytokine receptors, and Toll-like receptors among other immune response genes is also seen as high value as genomic sequencing becomes less expensive. Animal models which incorporate and assess not only the genetic anlagen but also the inflammatory cells and the presence of microbial pathogen [PAMPs] and damage associated molecular pattern molecules [DAMPs] are necessary. Identifying micro-RNAs involved in regulating the response to damage or injury are seen as highly promising. Although no therapeutic strategies to prevent or treat cancers based on insights into inflammatory pathways are currently approved for the common epithelial malignancies, there remains substantial interest in agents targeting COX2 or PPAR?, ethyl pyruvate, as well as steroids and several novel agents on the horizon.

Glucokinase activators (GKAs) promise a new pharmacotherapy for diabetics  

PubMed Central

The glucose-phosphorylating enzyme glucokinase, a promising target for developing new antidiabetic agents, was identified through the combined efforts of basic research and human biochemical genetics. Allosteric glucokinase activators (GKAs) were discovered by high-throughput screening of a large compound library and first reported in 2003. GKAs stimulate insulin release and glucose metabolism in the liver thereby lowering blood sugar, and promising trials in humans demonstrate that they are highly effective in patients with type 2 diabetes mellitus. Many companies are now attempting to develop effective and safe GKAs for treating diabetics.

Inferences from counterfactual threats and promises.  

PubMed

We examine how people understand and reason from counterfactual threats, for example, "if you had hit your sister, I would have grounded you" and counterfactual promises, for example, "if you had tidied your room, I would have given you ice-cream." The first experiment shows that people consider counterfactual threats, but not counterfactual promises, to have the illocutionary force of an inducement. They also make the immediate inference that the action mentioned in the "if" part of the counterfactual threat and promise did not occur. The second experiment shows that people make more negative inferences (modus tollens and denial of the antecedent) than affirmative inferences (modus ponens and affirmation of the consequent) from counterfactual threats and promises, unlike indicative threats and promises. We discuss the implications of the results for theories of the mental representations and cognitive processes that underlie conditional inducements. PMID:22580411

The Promise and Reality of Pharmacogenetics in Psychiatry  

PubMed Central

Summary Existing psychotropic medications for the treatment of mental illnesses, including antidepressants, mood stabilizers, and antipsychotics, are clinically sub-optimal. They are effective in only a subset of patients or produce partial responses, and they are often associated with debilitating side effects that discourage adherence. There is growing enthusiasm in the promise of pharmacogenetics to personalize the use of these treatments to maximize their efficacy and tolerability. However, there is still a long way to go before this promise becomes a reality. In this article, we review the progress that has been made in research towards understanding how genetic factors influence psychotropic drug responses and the challenges that lie ahead in translating the research findings into clinical practices that yield tangible benefits for patients with mental illnesses.

Polymer electrolytes, problems, prospects, and promises  

SciTech Connect

Ionically conducting polymer electrolytes have generated, in recent years, wide-spread interest as candidate materials for a number of applications including high energy density and power lithium batteries. In the early 70s the first measurements of ionic conductivity in polyethylene oxide (PEO)-salt complexes were carried out. However, Armand was the first one to realize potential of these complexes (polymer-salt complexes) as practical ionically conducting materials for use as electrolytes in lithium batteries. Subsequent research efforts identified the limitations and constraints of the polymer electrolytes. These limitations include poor ionic conductivity at RT (< 10{sup {minus}8} S/cm), low cation transport number (<0.2) etc. Several different approaches have been made to improving the ionic conductivity of the polymer electrolytes while retaining the flexibility, processibility, ease of handling and relatively low impact on the environment that polymers inherently possess. This paper- reviews evolution of polymer electrolytes from conventional PEO-LiX slat complexes to the more conducting polyphosphazene and copolymers, gelled electrolytes etc. We also review the various chemical approaches including modifying PEO to synthesizing complicated polymer architecture. In addition, we discuss effect of various lithium salts on the conductivity of PEO-based polymers. Charge/discharge and cycle life data of polymer cells containing oxide and chalcogenide cathodes and lithium (Li) anode are reviewed. Finally, future research directions to improve the electrolyte properties are discussed.

Defining Normal and Abnormal Fetal Growth: Promises and Challenges  

PubMed Central

Normal fetal growth is a critical component of a healthy pregnancy and influences the long-term health of the offspring. However, defining normal and abnormal fetal growth has been a long-standing challenge in clinical practice and research. The authors review various references and standards that are widely used to evaluate fetal growth, and discuss common pitfalls of current definitions of abnormal fetal growth. Pros and cons of different approaches to customize fetal growth standards are described. The authors further discuss recent advances towards an integrated definition for fetal growth restriction. Such a definition may incorporate fetal size with the status of placental health measured by maternal and fetal Doppler velocimetry and biomarkers, biophysical findings and genetics. Although the concept of an integrated definition appears promising, further development and testing are required. An improved definition of abnormal fetal growth should benefit both research and clinical practice.

Do promises matter? An exploration of the role of promises in psychological contract breach.  

PubMed

Promises are positioned centrally in the study of psychological contract breach and are argued to distinguish psychological contracts from related constructs, such as employee expectations. However, because the effects of promises and delivered inducements are confounded in most research, the role of promises in perceptions of, and reactions to, breach remains unclear. If promises are not an important determinant of employee perceptions, emotions, and behavioral intentions, this would suggest that the psychological contract breach construct might lack utility. To assess the unique role of promises, the authors manipulated promises and delivered inducements separately in hypothetical scenarios in Studies 1 (558 undergraduates) and 2 (441 employees), and they measured them separately (longitudinally) in Study 3 (383 employees). The authors' results indicate that breach perceptions do not represent a discrepancy between what employees believe they were promised and were given. In fact, breach perceptions can exist in the absence of promises. Further, promises play a negligible role in predicting feelings of violation and behavioral intentions. Contrary to the extant literature, the authors' findings suggest that promises may matter little; employees are concerned primarily with what the organization delivers. PMID:19702368

Promise and Pitfalls of Using Grain Size Analysis to Identify Glacial Sediments in Alpine Lake Cores.  

NASA Astrophysics Data System (ADS)

Lakes fed by glacier outwash should have a clastic particle-size record distinct from non-glacial lakes in the same area, but do they? The unique turquoise color of alpine glacial lakes reflects the flux of suspended clastic glacial rock flour to those lakes; conversely, lakes not fed by outwash are generally clear with sediments dominated by organics or slope-wash from nearby hillslopes. This contrast in sediment types and sources should produce a distinct and measureable different in grain sizes between the two settings. Results from a variety of lakes suggest the actual situation is often more subtle and complex. I compare grain size results to other proxies to assess the value of grain size analysis for paleoglacier studies. Over the past 10 years, my colleagues and I have collected and analyzed sediment cores from a wide variety of lakes below small alpine glaciers in an attempt to constrain the timing and magnitude of alpine glaciation in those basins. The basic concept is that these lakes act as continuous catchments for any rock flour produced upstream by glacier abrasion; as a glacier grows, the flux of rock flour to the lake will also increase. If the glacier disappears entirely, rock flour deposition will also cease in short order. We have focused our research in basins with simple sedimentologic settings: mostly small, high-altitude, stripped granitic or metamorphic cirques in which the cirque glaciers are the primary source of clastic sediments. In most cases, the lakes are fed by meltwater from a modern glacier, but were ice free during the earlier Holocene. In such cases, the lake cores should record formation of and changes in activity of the glacier upstream. We used a Malvern Mastersizer 2000 laser particle size analyzer for our grain size analyses, as well as recording magnetic susceptibility, color, and organics for the same cores. The results indicate that although lakes often experience increases in silt and clay-size (<0.63 mm) clastic particles when a glacier is present upstream, the signal can be highly variable and complex, most likely the result of stochastic processes in the basin. Our analyses indicate that although particle size reflects glacier activity upstream, it is rarely the best record of glacier change and is most useful in combination with other proxies, most notably MS, color, and organic content.

The promise of molecular epidemiology in defining the association between radiation and cancer  

SciTech Connect

Molecular epidemiology involves the inclusion in epidemiologic studies of biologic measurements made at a genetic and molecular level and aims to improve the current knowledge of disease etiology and risk. One of the goals of molecular epidemiology studies of cancer is to determine the role of environmental and genetic factors in initiation and progression of malignancies and to use this knowledge to develop preventive strategies. This approach promises extraordinary opportunities for revolutionizing the practice of medicine and reducing risk. However, this will be accompanied by the need to address and resolve many challenges, such as ensuring the appropriate interpretation of molecular testing and resolving associated ethical, legal, and social issues. Traditional epidemiologic approaches determined that exposure to ionizing radiation poses significantly increased risk of leukemia and several other types of cancer. Such studies provided the basis for setting exposure standards to protect the public and the workforce from potentially adverse effects of ionizing radiation. These standards were set by using modeling approaches to extrapolate from the biological effects observed in high-dose radiation studies to predicted, but mostly immeasurable, effects at low radiation doses. It is anticipated that the addition of the molecular parameters to the population-based studies will help identify the genes and pathways characteristic of cancers due to radiation exposure of individuals, as well as identify susceptible or resistant subpopulations. In turn, the information about the molecular mechanisms should aid to improve risk assessment. While studies on radiogenic concerns are currently limited to only a few candidate genes, the exponential growth of scientific knowledge and technology promises expansion of knowledge about identity of participating genes and pathways in the future. This article is meant to provide an introductory overview of recent advances in understanding of carcinogenesis at the molecular level, with an emphasis of the aspects that may be of use in establishing the association between radiation and cancer.

The Promise of Wave Power (Invited)  

NASA Astrophysics Data System (ADS)

The solutions to today's energy challenges need to be explored through alternative, renewable and clean energy sources to enable diverse energy resource plans. An extremely abundant and promising source of energy exists in the world's oceans: it is estimated that if 0.2 % of the oceans' untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy exists in the forms of wave, tidal, marine currents, thermal (temperature gradient) and salinity. Among these forms, significant opportunities and benefits have been identified in the area of ocean wave energy extraction, i.e., harnessing the motion of the ocean waves, and converting that motion into electrical energy. Ocean wave energy refers to the kinetic and potential energy in the heaving motion of ocean waves. Wave energy is essentially concentrated solar energy (as is wind energy). The heating of the earth’s surface by the sun (with other complex processes) drives the wind, which in turn blows across the surface of the ocean to create waves. At each stage of conversion, the power density increases. Ocean wave power offers several attractive qualities, including high power density, low variability, and excellent forecastability. A typical large ocean wave propogates at around 12 m/s with very little attenuation across the ocean. If the waves can be detected several hundred kilometers off shore, there can be 10 hours or more of accurate forecast horizon. In fact, analysis has shown good forecast accuracy up to 48 hours in advance. Off the coast Oregon, the yearly average wave power is approximately 30 kW per meter of crestlength (i.e., unit length transverse to the direction of wave propagation and parallel to the shore.) This compares very favorably with power densities of solar and wind, which typically range in the several hundreds of Watts per square meter. Globally, the wave energy resource is stronger on the west coasts of large landmasses and increases in strength toward the poles. This phenomenon is due to the prevailing west to east global winds known as the "westerlies" found in the Northern and Southern hemispheres between 30 and 60 degrees latitude. Correspondingly, the west coast of the United States, the west coast of Australia, and the coastal regions of Europe have seen the greatest wave energy industrial activity to date. Ocean wave energy has great potential to be a significant contributor of renewable power for many regions in the world. For the West coast of the US alone, the total wave energy resource is estimated at 440 TWh/yr, which is more than the typical total US annual hydroelectric production (270 TWh in 2003). For US west coast states, a fully developed wave energy industry could be a significant contributor to renewable energy portfolio standards. Within the next few years, several utility-scale wave energy converters are planned for grid connection (e.g., Ocean Power Technologies and Columbia Power Technologies in Oregon, USA), with plans for more utility-scale development to follow soon after. This presentation will cover the physical basics of wave energy, examples of commercial technology, challenges opportunities for research, and an update on the wave energy research and developments at leading commercial, industrial, and academic institutions around the world.

Thiomers: promising platform for macromolecular drug delivery.  

PubMed

The application of macromolecules as therapeutic agents holds great promise for several major disorders such as cancer and cardiovascular disease. However, their use is limited by the lack of efficient, safe and specific delivery strategies. A promising strategy to overcome these challenges might be the use of thiolated polymers or designated thiomers. Thiomers are synthesized by immobilization of sulfhydryl bearing ligands on a polymeric backbone of well-established polymers. These multifunctional polymeric excipients show advantages in mucoadhesion, enzyme and efflux pump inhibition in comparison to unmodified polymers. One obstacle in the use of thiomers is that they are prone to oxidation at lower pH but this could be solved by introducing a completely new generation of thiomers, namely, the preactivated thiomer generation. Preactivated thiomers are mixed disulfides, which exhibit oxidation resistance and, beyond that, improved thiomer features. This review summarizes recent findings of polymeric excipients for macromolecular drug delivery as well as their synthesis and distinctive features. PMID:23190108

Foundations, promises and uncertainties of personalized medicine.  

PubMed

Personalized medicine introduces the promise to use molecular markers that signal the risk of disease or its presence before clinical signs and symptoms appear. This information underlies a new healthcare strategy focused on prevention and early intervention, rather than reaction to advanced stages of disease. Such a strategy can delay disease onset or minimize symptom severity. The molecular foundations that enable personalized medicine include detection of variation in nucleotide sequence of genes and in characteristic patterns of gene expression, proteins and metabolites. Genetic and molecular patterns are correlated with disease manifestations, drug responses, treatment prognosis, or prediction of predisposition to future disease states. However, the uncertainties for personalized medicine are considerable, including economic, ethical, legal, and societal questions. Although much of its promise remains unproven to date, the foundations of personalized medicine appear solid and evidence is accumulating rapidly pointing to its growing importance in healthcare (Fig. 1).

Antimicrobial peptides: promising compounds against pathogenic microorganisms.  

PubMed

In the last decades, the indiscriminate use of conventional antibiotics has generated high rates of microbial resistance. This situation has increased the need for obtaining new antimicrobial compounds against infectious diseases. Among these, antimicrobial peptides (AMPs) constitute a promising alternative as therapeutic agents against various pathogenic microbes. These therapeutic agents can be isolated from different organisms, being widespread in nature and synthesized by microorganisms, plants and animals (both invertebrates and vertebrates). Additionally, AMPs are usually produced by a non-specific innate immune response. These peptides are involved in the inhibition of cell growth and in the killing of several microorganisms, such as bacteria, fungi, enveloped viruses, protozoans and other parasites. They have many interesting properties as potential antibiotics, such as relatively small sizes (below 25-30 kDa), amphipathic structures, cationic nature, and offer low probability for the generation of microbial resistance. In recent years, many novel AMPs, with very promising therapeutic properties, have been discovered. These peptides have been the base for the production of chemical analogs, which have been designed, chemically synthesized and tested in vitro for their antimicrobial activity. This review is focused on antibacterial (against Gram (-) and Gram (+) bacteria) and antifungal peptides, discussing action mode of AMPs, and recent advances in the study of the molecular basis of their anti-microbial activity. Finally, we emphasize on their current pharmacological development, future directions and applications of AMPs as promising antibiotics of therapeutic use for microbial infections. PMID:24533812

Towards quantum-enhanced precision measurements: Promise and challenges  

NASA Astrophysics Data System (ADS)

Quantum metrology holds the promise of improving the measurement precision beyond the limit of classical approaches. To achieve such enhancement in performance requires the development of quantum estimation theories as well as novel experimental techniques. In this article, we provide a brief review of some recent results in the field of quantum metrology. We emphasize that the unambiguous demonstration of the quantum-enhanced precision needs a careful analysis of the resources involved. In particular, the implementation of quantum metrology in practice requires us to take into account the experimental imperfections included, for example, particle loss and dephasing noise. For a detailed introduction to the experimental demonstrations of quantum metrology, we refer the reader to another article ‘Quantum metrology’ in the same issue.

The Promise and Perils of Stem Cell Therapeutics  

PubMed Central

Stem cells are the seeds of tissue repair and regeneration and a promising source for novel therapies. However, apart from hematopoietic stem cell (HSC) transplantation for hematologic disease, essentially all other stem cell treatments remain experimental. High hopes have inspired numerous clinical trials, but it has been difficult to obtain unequivocal evidence for robust clinical benefit, likely owing to our primitive state of knowledge about therapeutic mechanisms. Outside the standard clinical trial network unproven therapies are being widely practiced in an open market, which threatens the cause of legitimate clinical investigation of the safety and efficacy of stem cell interventions. Here is one practitioner's perspective on the challenges and technical barriers that must be overcome for novel stem cell therapies to achieve meaningful clinical impact.

Nanotechnology: Promises and challenges for tomorrow  

SciTech Connect

Nanotechnology is based on the ability to create and utilize materials, devices and systems through control of the matter at the nanometer scale. If successful, nanotechnology is expected to lead to broad new technological developments. The efficiency of energy conversion can be increased through the use of nanostructured materials with enhanced magnetic, light emission or wear resistant properties. Energy generation using nanostructured photovoltaics or nanocluster driven photocatalysis could fundamentally change the economic viability of renewable energy sources. In addition, the ability to imitate molecular processes found in living organisms may be key to developing highly sensitive and discriminating chemical and biological sensors. Such sensors could greatly expand the range of medical home testing as well as provide new technologies to counter the spread of chemical and biological weapons. Even the production of chemicals and materials could be revolutionized through the development of molecular reactors that can promote low energy chemical pathways for materials synthesis. Although nanotechnologies hold great promise, significant scientific challenges must be addressed before they can convert that promise into a reality. A key challenge in nanoscience is to understand how nano-scale tailoring of materials can lead to novel and enhanced functions. The authors' laboratory, for example, is currently making broad contributions in this area by synthesizing and exploring nanomaterials ranging from layered structures for electronics/photonics to novel nanocrystalline catalysts. They are even adapting functions from biological molecules to synthesize new forms of nanostructured materials.

Promises in intelligent plant control systems  

SciTech Connect

The control system is the brain of a power plant. The traditional goal of control systems has been productivity. However, in nuclear power plants the potential for disaster requires safety to be the dominant concern, and the worldwide political climate demands trustworthiness for nuclear power plants. To keep nuclear generation as a viable option for power in the future, trust is the essential critical goal which encompasses all others. In most of today's nuclear plants the control system is a hybrid of analog, digital, and human components that focuses on productivity and operates under the protective umbrella of an independent engineered safety system. Operation of the plant is complex, and frequent challenges to the safety system occur which impact on their trustworthiness. Advances in nuclear reactor design, computer sciences, and control theory, and in related technological areas such as electronics and communications as well as in data storage, retrieval, display, and analysis have opened a promise for control systems with more acceptable human brain-like capabilities to pursue the required goals. This paper elaborates on the promise of futuristic nuclear power plants with intelligent control systems and addresses design requirements and implementation approaches.

Microalgae and biofuels: a promising partnership?  

PubMed

Microalgae have much higher lipid yields than those of agricultural oleaginosous crops, and they do not compromise arable land. Despite this, current microalga-based processes suffer from several constraints pertaining to the biocatalyst and the bioreactor, which hamper technologically and economically feasible scale-up. Here, we briefly review recent active research and development efforts worldwide, and discuss the most relevant shortcomings of microalgal biofuels. This review goes one step further relative to related studies, because it tackles otherwise scarcely mentioned issues - for example, heterotrophic versus autotrophic metabolism, alkane versus glyceride synthesis, conduction versus bubbling of CO(2), and excretion versus accumulation of lipids. Besides promising solutions that have been hypothesized and arise from multidisciplinary approaches, we also consider less conventional ones. Microalgae and biofuels hold indeed a promising partnership, but a fully competitive technology is not expected to be available before the end of this decade, because the need for one order of magnitude increase in productivity requires development of novel apparatuses and transformed cells.

The promising trajectory of autism therapeutics discovery.  

PubMed

Pharmacological interventions for neurodevelopmental disorders are increasingly tractable. Autism is a neurodevelopmental disorder that affects approximately 1% of the population. Currently, the standard of care is early behavioral therapy. No approved medical treatments for the diagnostic symptoms are available. Strong evidence for genetic causes of autism implicates proteins that mediate synaptic transmission and structure. Mouse models with targeted mutations in these synaptic genes display behavioral symptoms relevant to the social communication abnormalities and repetitive behaviors that define autism spectrum disorder (ASD), along with biological abnormalities in synaptic physiology and morphology. As we discuss here, promising pharmacological targets, emerging from the mouse model studies, are now being pursued in early clinical trials. Thus, a high-prevalence disorder that was previously considered to be medically untreatable is now moving into the therapeutic arena. PMID:24362109

Promising applications of forecasting include better targeting of disease management as well as innovative patient care approaches such as personalized health insurance and clinical decision support systems. In addition, stakeholders will use predictions to advance their organizational agendas, and unintended consequences could arise. Forecasting-based interventions might have uncertain effectiveness, focus on cost savings rather than long-term health, or specifically exclude disadvantaged populations. Policy makers, health plans, and method developers should adopt strategies that address these concerns in order to maximize the benefit of healthcare forecasting on the long-term health of patients.

Diabetic macular edema: New promising therapies.  

PubMed

The treatment of diabetic macular edema is rapidly evolving. The era of laser therapy is being quickly replaced by an era of pharmacotherapy. Several pharmacotherapies have been recently developed for the treatment of retinal vascular diseases such as diabetic macular edema. Several intravitreal injections or sustained delivery devices have undergone phase 3 testing while others are currently being evaluated. The results of clinical trials have shown the superiority of some of these agents to laser therapy. However, with the availability of several of these newer agents, it may be difficult to individualize treatment options especially those patients respond differently to various therapies. As such, more effort is still needed in order to determine the best treatment regimen for a given patient. In this article, we briefly summarize the major new therapeutic additions for the treatment of diabetic macular edema and allude to some future promising therapies. PMID:24379924

Review of Some Promising Fractional Physical Models  

NASA Astrophysics Data System (ADS)

Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law nonlocality, power-law long-term memory or fractal properties by using integrations and differentiation of non-integer orders, i.e., by methods in the fractional calculus. This paper is a review of physical models that look very promising for future development of fractional dynamics. We suggest a short introduction to fractional calculus as a theory of integration and differentiation of noninteger order. Some applications of integro-differentiations of fractional orders in physics are discussed. Models of discrete systems with memory, lattice with long-range inter-particle interaction, dynamics of fractal media are presented. Quantum analogs of fractional derivatives and model of open nano-system systems with memory are also discussed.

Liver support systems: promise and reality.  

PubMed

Effective liver support is needed for a variety of indications. A large number of both biological (containing hepatocytes) and non-biological extracorporeal liver support systems have been described in the literature over the last 50 years. Despite this, there is a paucity of good quality randomized control data examining the effectiveness of these therapies in human liver failure. In this review article, we examine the available data, with particular emphasis on the current front runners, the MARS and HepatAssist systems. Other problems associated with the development of these liver support systems are also discussed. Although promising in animal studies, we conclude that the use of these technologies is not supported currently by a sufficient evidence base to recommend them for routine clinical use and that a lack of understanding about the critical functions required of a liver support system is retarding a more rational approach to the design of these systems.

Furfural--a promising platform for lignocellulosic biofuels.  

PubMed

Furfural offers a promising, rich platform for lignocellulosic biofuels. These include methylfuran and methyltetrahydrofuran, valerate esters, ethylfurfuryl and ethyltetrahydrofurfuryl ethers as well as various C(10)-C(15) coupling products. The various production routes are critically reviewed, and the needs for improvements are identified. Their relative industrial potential is analysed by defining an investment index and CO(2) emissions as well as determining the fuel properties for the resulting products. Finally, the most promising candidate, 2-methylfuran, was subjected to a road trial of 90,000 km in a gasoline blend. Importantly, the potential of the furfural platform relies heavily on the cost-competitive production of furfural from lignocellulosic feedstock. Conventional standalone and emerging coproduct processes-for example, as a coproduct of cellulosic ethanol, levulinic acid or hydroxymethyl furfural-are expensive and energetically demanding. Challenges and areas that need improvement are highlighted. In addition to providing a critical review of the literature, this paper also presents new results and analysis in this area.

Promises of advanced technology realized at Martin  

SciTech Connect

The 2,488-MW Martin station is a gas/oil-fired facility that embodies today`s demand for flexible operations, technological advances, and reduced production costs. Martin station first rose up from the Everglades in the early 1980s, with the construction of two 814-MW oil-fired steam plants, Units 1 and 2. Natural-gas-firing capability was added to the balanced-draft, natural-circulation boilers in 1986, increasing the station`s fuel flexibility. Martin then leaped into the headlines in the early 1990s when it added combined-cycle (CC) Units 3 and 4. With this 860-MW expansion, FP and L boldly became the fleet leader for the advanced, 2350F-class 7FA gas turbines. Further pushing he technology envelope, the CC includes a three-pressure reheat steam system that raises net plant efficiency for Units 3 and 4 to 54%, on a lower-heating-value (LHV) basis. Incorporating the reheat cycle required significant redesign of the gas-turbine/heat-recovery steam generator (HRSG) train, in order to maintain a rapid startup capability without exceeding metallurgical limits. Perhaps even more important than the technological achievements, Martin stands out from the crowd for its people power, which ensured that the promises of advanced technology actually came to fruition. This station`s aggressive, empowered O and M team shows that you can pioneer technology, reduce operating costs, and deliver high availability--all at the same time.

GEOTEC-a promising energy alternative  

SciTech Connect

Geothermal reconnaissance has shown a promising resource at the base of three clustered volcanoes on Adak Island, located along the Aleutian arc of Alaska. Geophysical surveys revealed areas of abrupt and steep gravitational gradients and high electrical conductivity over the volcanoes, indicating possible subsurface magma. Geochemical analyses indicated a potential reservoir temperature of 180/sup 0/C. The nearby Bering Sea has a surface temperature ranging between 3/sup 0/ and 8/sup 0/C year-round and would provide for high heat reinjection. The combination of geothermal and ocean sink resources could result in a GEOTEC plant having an overall thermal efficiency approaching one-third that of the present diesel-electric generating system at the Naval Air Station on Adak. The more than 5000 permanently stationed personnel at the station consume over 8 million gal of JP-5 fuel for space heating and electrical power. Presently, electric energy on Adak costs 250-350 mils/kilowatt-hour. Preliminary estimates of the cost of electric power from a GEOTEC plant are about 200 mils/kilowatt-hour. A GEOTEC plant would also be a secure alternative energy source for the US Navy.

Polyfluoroalkoxyphosphazenes — a Promising Class of Organoelemental Polymers  

NASA Astrophysics Data System (ADS)

The results of the synthesis of polyfluoroalkoxyphosphazenes and also polyorganophosphazenes containing various non-fluorinated organic groups as substituents at the phosphorus atoms together with fluoroalkoxy-groups are surveyed. The characteristics of the formation of these polymers by the chemical modification of polydichlorophosphazene are examined. A systematic account is given of the literature data on the properties of polyfluoroalkoxyphosphazenes and their practical applications. The ways in which varieties of the macromolecules of these polymers arise and the influence of the nature and number of anomalous units on their properties are considered. Attention is drawn to a fundamentally important characteristic feature of polyfluoroalkoxyphosphazenes, namely the high sensitivity of their properties to anomalous units when the content of the latter is less than 1 mole %.

Alcoholism research: delivering on the promise.  

PubMed

Prospects for research advances in alcoholism are very promising, because of the explosion in the neurosciences and advances in epidemiology and typology of the disorder. For example, the field is now ready for molecular genetics studies of the early onset form of alcoholism that is transmitted from father to son with high penetrance. Leading neuroscientists are being recruited into alcoholism research. Paradoxically, this time of new hope coincides with challenges to the scientific enterprise, such as the animal rights movement and impatience with the scientific process in the face of the public health emergencies represented by acquired immunodeficiency syndrome (AIDS) and drug abuse. The emergence of genetically based subtypes of alcoholism suggests that at least two discrete illness processes are involved. Mounting evidence from spinal fluid studies has rekindled interest in a key role for serotonin in the early onset form of alcoholism. One hypothesis now being explored is that genetically low brain serotonin function may be part of the predisposition to this form of alcoholism. It is known that acute alcohol intake transiently increases brain serotonin turnover. Thus, drinking might be viewed as an attempt to correct a deficit, only to produce further serotonin depletion as the drug's effect wears off, setting up a vicious cycle of repeated attempts to self-medicate. Impulsive, violent, and suicidal behavior as well as alcohol abuse are associated with the low brain serotonin activity. Persons with these problems suffer from circadian rhythm and glucose metabolism disturbances that may also be mediated by serotonin. New pharmacological probes are now available to tease out the mechanisms of altered serotonin function. The progressively deteriorating course of severe episodic alcoholism in many ways parallels the process of electrically kindled seizures in experimental animals. There is evidence that repeated withdrawal episodes may kindle a worsening course, including phobic disorders, perhaps by triggering a hyper-reactive noradrenalin system. PMID:2847208

Materializing research promises: opportunities, priorities and conflicts in translational medicine  

PubMed Central

There is considerable evidence that the translation rate of major basic science promises to clinical applications has been inefficient and disappointing. The deficiencies of translational science have often been proposed as an explanation for this failure. An alternative explanation is that until recently basic science advances have made oversimplified assumptions that have not matched the true etiological complexity of most common diseases; while clinical science has suffered from poor research practices, overt biases and conflicts of interest. The advent of molecular medicine and the recasting of clinical science along the principles of evidence-based medicine provide a better environment where translational research may now materialize its goals. At the same time, priority issues need to be addressed in order to exploit the new opportunities. Translational research should focus on diseases with global impact, if true progress is to be made against human suffering. The health outcomes of interest for translational efforts need to be carefully defined and a balance must be struck between the subjective needs of healthcare consumers and objective health outcomes. Development of more simple, practical and safer interventions may be as important a target for translational research as the development of cures for diseases where no effective interventions are available at all. Moreover, while the role of the industry is catalytic in translating research advances to licensed interventions, academic independence needs to be sustained and strengthened at a global level. Conflicts of interest may stifle translational research efforts internationally. The profit motive is unlikely to be sufficient alone to advance biomedical research towards genuine progress.

Homogeneous Immunoassays: Historical Perspective and Future Promise  

NASA Astrophysics Data System (ADS)

The founding and growth of Syva Company is examined in the context of its leadership role in the development of homogeneous immunoassays. The simple mix and read protocols of these methods offer advantages in routine analytical and clinical applications. Early homogeneous methods were based on insensitive detection of immunoprecipitation during antigen/antibody binding. The advent of reporter groups in biology provided a means of quantitating immunochemical binding by labeling antibody or antigen and physically separating label incorporated into immune complexes from free label. Although high sensitivity was achieved, quantitative separations were experimentally demanding. Only when it became apparent that reporter groups could provide information, not only about the location of a molecule but also about its microscopic environment, was it possible to design practical non-separation methods. The evolution of early homogenous immunoassays was driven largely by the development of improved detection strategies. The first commercial spin immunoassays, developed by Syva for drug abuse testing during the Vietnam war, were followed by increasingly powerful methods such as immunochemical modulation of enzyme activity, fluorescence, and photo-induced chemiluminescence. Homogeneous methods that quantify analytes at femtomolar concentrations within a few minutes now offer important new opportunities in clinical diagnostics, nucleic acid detection and drug discovery.

Multivariate meta-analysis: Potential and promise  

PubMed Central

The multivariate random effects model is a generalization of the standard univariate model. Multivariate meta-analysis is becoming more commonly used and the techniques and related computer software, although continually under development, are now in place. In order to raise awareness of the multivariate methods, and discuss their advantages and disadvantages, we organized a one day ‘Multivariate meta-analysis’ event at the Royal Statistical Society. In addition to disseminating the most recent developments, we also received an abundance of comments, concerns, insights, critiques and encouragement. This article provides a balanced account of the day's discourse. By giving others the opportunity to respond to our assessment, we hope to ensure that the various view points and opinions are aired before multivariate meta-analysis simply becomes another widely used de facto method without any proper consideration of it by the medical statistics community. We describe the areas of application that multivariate meta-analysis has found, the methods available, the difficulties typically encountered and the arguments for and against the multivariate methods, using four representative but contrasting examples. We conclude that the multivariate methods can be useful, and in particular can provide estimates with better statistical properties, but also that these benefits come at the price of making more assumptions which do not result in better inference in every case. Although there is evidence that multivariate meta-analysis has considerable potential, it must be even more carefully applied than its univariate counterpart in practice.

Neuroimaging in psychiatric pharmacogenetics research: the promise and pitfalls.  

PubMed

The integration of research on neuroimaging and pharmacogenetics holds promise for improving treatment for neuropsychiatric conditions. Neuroimaging may provide a more sensitive early measure of treatment response in genetically defined patient groups, and could facilitate development of novel therapies based on an improved understanding of pathogenic mechanisms underlying pharmacogenetic associations. This review summarizes progress in efforts to incorporate neuroimaging into genetics and treatment research on major psychiatric disorders, such as schizophrenia, major depressive disorder, bipolar disorder, attention-deficit/hyperactivity disorder, and addiction. Methodological challenges include: performing genetic analyses in small study populations used in imaging studies; inclusion of patients with psychiatric comorbidities; and the extensive variability across studies in neuroimaging protocols, neurobehavioral task probes, and analytic strategies. Moreover, few studies use pharmacogenetic designs that permit testing of genotype × drug effects. As a result of these limitations, few findings have been fully replicated. Future studies that pre-screen participants for genetic variants selected a priori based on drug metabolism and targets have the greatest potential to advance the science and practice of psychiatric treatment.

The promise--and peril--of integrated cost systems.  

PubMed

Recent advances in managerial accounting have helped executives get the information they need to make good strategic decisions. But today's enterprise resource planning systems promise even greater benefits--the chance to integrate activity-based costing, operational-control, and financial reporting systems. But managers need to approach integration very thoughtfully, or they could end up with a system that drives decision making in the wrong direction. Operational-control and ABC systems have fundamentally different purposes. Their requirements for accuracy, timeliness, and aggregation are so different that no single, fully integrated approach can be adequate for both purposes. If an integrated system used real-time cost data instead of standard rates in its ABC subsystem, for example, the result would be dangerously distorted messages about individual product profitability--and that's precisely the problem ABC systems were originally designed to address. Proper linkage and feedback between the two systems is possible, however. Through activity-based budgeting, the ABC system is linked directly to operations control: managers can determine the supply and practical capacity of resources in forthcoming periods. Linking operational control to ABC is also possible. The activity-based portion of an operational control system collects information that, while it mustn't be fed directly into the activity-based strategic cost system, can be extremely useful once it's been properly analyzed. Finally, ABC and operational control can be linked to financial reporting to generate cost of goods sold and inventory valuations--but again, with precautions. PMID:10181585

Smaller sulfur molecules promise better lithium-sulfur batteries.  

PubMed

The lithium-sulfur battery holds a high theoretical energy density, 4-5 times that of today's lithium-ion batteries, yet its applications have been hindered by poor electronic conductivity of the sulfur cathode and, most importantly, the rapid fading of its capacity due to the formation of soluble polysulfide intermediates (Li(2)S(n), n = 4-8). Despite numerous efforts concerning this issue, combatting sulfur loss remains one of the greatest challenges. Here we show that this problem can be effectively diminished by controlling the sulfur as smaller allotropes. Metastable small sulfur molecules of S(2-4) were synthesized in the confined space of a conductive microporous carbon matrix. The confined S(2-4) as a new cathode material can totally avoid the unfavorable transition between the commonly used large S(8) and S(4)(2-). Li-S batteries based on this concept exhibit unprecedented electrochemical behavior with high specific capacity, good cycling stability, and superior rate capability, which promise a practicable battery with high energy density for applications in portable electronics, electric vehicles, and large-scale energy storage systems.

Promising avenues of therapeutics for bipolar illness  

PubMed Central

Basic scientific advances in understanding the neuropsychobioloqy of bipolar disorder have given us a multitude of opportunities to explore and exploit new avenues of therapeutics. Pharmacotherapeutic approaches include: neuropeptides (agonists such as thyrotropin-releasing hormone and antagonists such as corticotropin-releasing hormone), neurotrophic factors (especially brain-derived neurotrophic factor), and glutamatergic mechanisms (such as riluzole, ketamine, and antagonists of the NR-2B subunit of the glutamate receptor). Physiological interventions that would offer alternatives to electroconvulsive therapy include: repeated transcranial magnetic stimulation, especially at more intense stimulation parameters; magnetic stimulation therapy (seizures induced more focally by magnetic rather than electrical stimulation with resulting reduced meaning loss); vagal nerve stimulation, and deep brain stimulation. However, these, as well as the panoply of existing treatments, require further intensive investigation to place each of them in the proper therapeutic seguence and combination for the individual patient, based on development of better clinical and biological predictors of response. Large clinical trial networks and development of systematic research in clinical practice settings, such as that featured by the National Cancer institute for cancer chemotherapy, would greatly accelerate the progress in incorporating new, as well as existing, agents into the best treatment strategies. The bipolar disorders, which are increasingly recognized as complex, highly comorbid conditions with a high morbidity and mortality, of which the majority start in childhood and adolescence, are not likely to respond completely to any single new treatment agent, and new public health initiatives and research strategies are needed as much as any new single treatment advance.

The phenanthroindolizidine and phenanthroquinolizidine alkaloids, typified by tylophorine and cryptopleurine, are a family of plant-derived small molecules with significant therapeutic potential. The plant extracts have been used in herbal medicine and the isolated compounds have displayed a range of promising therapeutic activity such as anti-ameobicidal, anti-viral, anti-inflammatory and anti-cancer activity. Despite their therapeutic protential, no compounds in this class have fully passed clinical trials. Drawbacks include low in vivo anti-cancer activity, central nervous system toxicity and low natural availability. A number of biological effects of these compounds, such as protein and nucleic acid synthesis suppression, have been identified, but the specific biomolecular targets have not yet been identified. Significant effort has been expended in the synthesis and structure-activity-relationship (SAR) studies of these compounds with the hope that a new drug will emerge. This review will highlight important contributions to the isolation, synthesis, SAR and mechanism of action of the phenanthroindolizidine and pheanthroquinolizidine alkaloids.

Vernonia condensata Baker (Asteraceae): a promising source of antioxidants.  

PubMed

The present study evaluated the antioxidant potential of Vernonia condensata Baker (Asteraceae). Dried and powdered leaves were exhaustively extracted with ethanol by static maceration followed by partition to obtain the hexane, dichloromethane, ethyl acetate, and butanol fractions. Total phenols and flavonoids contents were determined through spectrophotometry and flavonoids were identified by HPLC-DAD system. The antioxidant activity was assessed by DPPH radical scavenging activity, TLC-bioautography, reducing power of Fe(+3), phosphomolybdenum, and TBA assays. The total phenolic content and total flavonoids ranged from 0.19 to 23.11?g/100?g and from 0.13 to 4.10 g/100?g, respectively. The flavonoids apigenin and luteolin were identified in the ethyl acetate fraction. The IC50 of DPPH assay varied from 4.28 to 75.10?µg/mL and TLC-bioautography detected the antioxidant compounds. The reducing power of Fe(+3) was 19.98 to 336.48? ?g/mL, while the reaction with phosphomolybdenum ranged from 13.54% to 32.63% and 56.02% to 135.00% considering ascorbic acid and rutin as reference, respectively. At 30?mg/mL, the ethanolic extract and fractions revealed significant effect against lipid peroxidation. All these data sustain that V. condensata is an important and promising source of bioactive substances with antioxidant activity. PMID:24489987

Using association rule mining to determine promising secondary phenotyping hypotheses  

PubMed Central

Motivation: Large-scale phenotyping projects such as the Sanger Mouse Genetics project are ongoing efforts to help identify the influences of genes and their modification on phenotypes. Gene–phenotype relations are crucial to the improvement of our understanding of human heritable diseases as well as the development of drugs. However, given that there are ?20 000 genes in higher vertebrate genomes and the experimental verification of gene–phenotype relations requires a lot of resources, methods are needed that determine good candidates for testing. Results: In this study, we applied an association rule mining approach to the identification of promising secondary phenotype candidates. The predictions rely on a large gene–phenotype annotation set that is used to find occurrence patterns of phenotypes. Applying an association rule mining approach, we could identify 1967 secondary phenotype hypotheses that cover 244 genes and 136 phenotypes. Using two automated and one manual evaluation strategies, we demonstrate that the secondary phenotype candidates possess biological relevance to the genes they are predicted for. From the results we conclude that the predicted secondary phenotypes constitute good candidates to be experimentally tested and confirmed. Availability: The secondary phenotype candidates can be browsed through at http://www.sanger.ac.uk/resources/databases/phenodigm/gene/secondaryphenotype/list.

Relationship of osteopathic medical licensure examinations with undergraduate admission measures and predictive value of identifying future performance in osteopathic principles and practice/osteopathic manipulative medicine courses and rotations.  

PubMed

Two hundred sixty-five students from four classes at one school of osteopathic medicine were studied to determine the correlation between several frequently used premedical admission criteria to predict performance on the early and current versions of the osteopathic medical licensure examinations. Further analysis evaluated the predictive value of the examination of the National Board of Osteopathic Medical Examiners (NBOME) and its successor, the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) in determining subsequent performance in the ascending levels of the examination sequence, as well as to predict performance in the courses and rotations of osteopathic principles and practice (OPP) and osteopathic manipulative medicine (OMM). This study also investigated the relationship between the early and later parts of the osteopathic medical licensure examinations. Analysis showed that of all premedical parameters, only the Medical College Aptitude Test score was positively correlated with performance on COMLEX-USA. In addition, a positive correlation was demonstrated between the performance in either Level 1 of COMLEX-USA or in the earlier form of the NBOME examination Part I and subsequent performance on the current Level 2 of COMLEX-USA or the old NBOME Part II. Finally, analysis indicated that COMLEX-USA predicted performance in OPP knowledge and skills. PMID:12462306

Uneasy promises: sexuality, health, and human rights.  

PubMed

Although attention to the links between health and human rights is growing globally, the full potential of a progressive human rights approach to health has not yet been explored, and it is even more faintly understood in the United States than in the rest of the world. At the same time, global claims for sexual rights, particularly for those identifying as gay, lesbian, transsexual, or bisexual, are increasingly being made as human rights claims. All of these approaches to rights advocacy risk limiting their own transformative impact unless advocates critique their own strategies. Paradoxically, using health as a way to bring attention to nonheteronormative sexualities can be both helpful and potentially dangerous, especially when coupled with human rights. Recognizing sexuality as a critical element of humanity, and establishing a fundamental human right to health, can play a role in broader social justice claims, but the tendency of both public health and human rights advocacy to "normalize" and regulate must be scrutinized and challenged.

Resistant starch: promise for improving human health.  

PubMed

Ongoing research to develop digestion-resistant starch for human health promotion integrates the disciplines of starch chemistry, agronomy, analytical chemistry, food science, nutrition, pathology, and microbiology. The objectives of this research include identifying components of starch structure that confer digestion resistance, developing novel plants and starches, and modifying foods to incorporate these starches. Furthermore, recent and ongoing studies address the impact of digestion-resistant starches on the prevention and control of chronic human diseases, including diabetes, colon cancer, and obesity. This review provides a transdisciplinary overview of this field, including a description of types of resistant starches; factors in plants that affect digestion resistance; methods for starch analysis; challenges in developing food products with resistant starches; mammalian intestinal and gut bacterial metabolism; potential effects on gut microbiota; and impacts and mechanisms for the prevention and control of colon cancer, diabetes, and obesity. Although this has been an active area of research and considerable progress has been made, many questions regarding how to best use digestion-resistant starches in human diets for disease prevention must be answered before the full potential of resistant starches can be realized.

Flight deck automation: Promises and realities  

NASA Technical Reports Server (NTRS)

Issues of flight deck automation are multifaceted and complex. The rapid introduction of advanced computer-based technology onto the flight deck of transport category aircraft has had considerable impact both on aircraft operations and on the flight crew. As part of NASA's responsibility to facilitate an active exchange of ideas and information among members of the aviation community, a NASA/FAA/Industry workshop devoted to flight deck automation, organized by the Aerospace Human Factors Research Division of NASA Ames Research Center. Participants were invited from industry and from government organizations responsible for design, certification, operation, and accident investigation of transport category, automated aircraft. The goal of the workshop was to clarify the implications of automation, both positive and negative. Workshop panels and working groups identified issues regarding the design, training, and procedural aspects of flight deck automation, as well as the crew's ability to interact and perform effectively with the new technology. The proceedings include the invited papers and the panel and working group reports, as well as the summary and conclusions of the conference.

Ethnography in community psychology: promises and tensions.  

PubMed

Community psychology recognizes the need for research methods that illuminate context, culture, diversity, and process. One such method, ethnography, has crossed into multiple disciplines from anthropology, and indeed, community psychologists are becoming community ethnographers. Ethnographic work stands at the intersection of bridging universal questions with the particularities of people and groups bounded in time, geographic location, and social location. Ethnography is thus historical and deeply contextual, enabling a rich, in-depth understanding of communities that is aligned with the values and goals of community psychology. The purpose of this paper is to elucidate the potential of ethnography for community psychology and to encourage its use within the field as a method to capture culture and context, to document process, and to reveal how social change and action occur within and through communities. We discuss the method of ethnography, draw connections to community psychology values and goals, and identify tensions from our experiences doing ethnography. Overall, we assert that ethnography is a method that resonates with community psychology and present this paper as a resource for those interested in using this method in their research or community activism.

The aim of this study was to identify specific biomarkers that could be used to screen for psoriatic arthritis (PsA), as well as to assess disease activity and treatment outcome in affected patients. Forty-three outpatients considered eligible for anti-TNF-? treatment (etanercept 50?mg/week) were enrolled. Serum samples of vascular endothelial growth factor (VEGF), metalloproteinase-3 (MMP3), pentraxin 3 (PTX3), and high-sensitive C-reactive protein (hs-CRP) were collected at baseline (t0) and after 6 (t6), 12 (t12), and 24 months (t24) of treatment. Baseline values were compared with those of a group of healthy controls matched for age and sex. Disease activity scores and functional tests (DAS28, BASDAI, PASI, BASFI, HAQ, VAS pain, and VAS patient global disease activity) after treatment were found to be significantly different from baseline values. At baseline, MMP3, hs-CRP and VEGF values in the PsA-patients were found to be significantly higher with respect to levels in the controls. There were no differences in the PTX3 values. MMP3 was significantly lower at t6 (P?

Identity Management Systems in Healthcare: The Issue of Patient Identifiers  

NASA Astrophysics Data System (ADS)

According to a recent recommendation of the European Commission, now is the time for Europe to enhance interoperability in eHealth. Although interoperability of patient identifiers seems promising for matters of patient mobility, patient empowerment and effective access to care, we see that today there is indeed a considerable lack of interoperability in the field of patient identification. Looking from a socio-technical rather than a merely technical point of view, one can understand the fact that the development and implementation of an identity management system in a specific healthcare context is influenced by particular social practices, affected by socio-economical history and the political climate and regulated by specific data protection legislations. Consequently, the process of making patient identification in Europe more interoperable is a development beyond semantic and syntactic levels. In this paper, we gives some examples of today’s patient identifier systems in Europe, discuss the issue of interoperability of (unique) patient identifiers from a socio-technical point of view and try not to ignore the ‘privacy side’ of the story.

Polymer Electrolytes:. Problems, Prospects, and Promises  

NASA Astrophysics Data System (ADS)

In 1975 P. V. Wright observed ionic conduction at elevated temperatures in polyethylene oxide (PEO) thin film electrolyte containing sodium salt. This seminal research generated wide spread interest in all-solid-state rechargeable lithium batteries. Armand took the cue from this observation and demonstrated the use of PEO/salt complex as electrolyte in lithium batteries. Soon after this a number of researchers have followed suit and studied the physical, electrical and transport properties of thin film PEO electrolyte. These studies have clearly identified the limitations of the PEO electrolyte. Chief among the limitations are a low cation transport number (t+), high glass transition temperature (Tg), and segmental motion of the polymer chain, which carries the cation through the bulk electrolyte. While low t+ leads to cell polarization and increase in cell resistance high Tg reduces conductivity at and around room temperature. For example, the conductivity of PEO electrolyte containing lithium salt is ~10-8 S/cm at room temperature. Attempts have been made to reduce Tg of PEO polymer by attaching PEO macromolecules to polyphosphazene (N=P) inorganic backbone, which is very flexible. Another material that has been investigated as a backbone material consists of Si-O chain. These two polymers exhibit a lower Tg and higher room temperature conductivity than the unmodified PEO. For example, the room temperature conductivity of the two polymers is around 10-5 S/cm - a 3 orders of magnitude increase in conductivity compared to unmodified PEO at around room temperature. Although this approach has yielded polymers with lower Tg, the t+ is still very low - ~0.25 - for lithium ion. Nano-ceramic particles of Al2O3, TiO2 etc. mechanically mixed with PEO electrolyte seem to increase t+. This approach also has inherent limitations regarding phase separation. The latest approach appears to involve integrating nano domains of inorganic moieties such as Si-O as part of the polymer chain. This approach not only has yielded an organic-inorganic polymer electrolyte with higher conductivity but appears to increase the t+ as well. An overview of the evolution of the all-solid-state polymer electrolyte in the last 25 years will be presented. This article addresses mainly the electrical and electrochemical properties and doesn't discuss the physicochemical and spectroscopic properties of dry polymer electrolytes.

Identifying tier one key suppliers.  

PubMed

In today's global marketplace, businesses are becoming increasingly reliant on suppliers for the provision of key processes, activities, products and services in support of their strategic business goals. The result is that now, more than ever, the failure of a key supplier has potential to damage reputation, productivity, compliance and financial performance seriously. Yet despite this, there is no recognised standard or guidance for identifying a tier one key supplier base and, up to now, there has been little or no research on how to do so effectively. This paper outlines the key findings of a BCI-sponsored research project to investigate good practice in identifying tier one key suppliers, and suggests a scalable framework process model and risk matrix tool to help businesses effectively identify their tier one key supplier base.

Exploring the promises of intersectionality for advancing women's health research  

PubMed Central

Women's health research strives to make change. It seeks to produce knowledge that promotes action on the variety of factors that affect women's lives and their health. As part of this general movement, important strides have been made to raise awareness of the health effects of sex and gender. The resultant base of knowledge has been used to inform health research, policy, and practice. Increasingly, however, the need to pay better attention to the inequities among women that are caused by racism, colonialism, ethnocentrism, heterosexism, and able-bodism, is confronting feminist health researchers and activists. Researchers are seeking new conceptual frameworks that can transform the design of research to produce knowledge that captures how systems of discrimination or subordination overlap and "articulate" with one another. An emerging paradigm for women's health research is intersectionality. Intersectionality places an explicit focus on differences among groups and seeks to illuminate various interacting social factors that affect human lives, including social locations, health status, and quality of life. This paper will draw on recently emerging intersectionality research in the Canadian women's health context in order to explore the promises and practical challenges of the processes involved in applying an intersectionality paradigm. We begin with a brief overview of why the need for an intersectionality approach has emerged within the context of women's health research and introduce current thinking about how intersectionality can inform and transform health research more broadly. We then highlight novel Canadian research that is grappling with the challenges in addressing issues of difference and diversity. In the analysis of these examples, we focus on a largely uninvestigated aspect of intersectionality research - the challenges involved in the process of initiating and developing such projects and, in particular, the meaning and significance of social locations for researchers and participants who utilize an intersectionality approach. The examples highlighted in the paper represent important shifts in the health field, demonstrating the potential of intersectionality for examining the social context of women's lives, as well as developing methods which elucidate power, create new knowledge, and have the potential to inform appropriate action to bring about positive social change.

Catalytically active nanomaterials: a promising candidate for artificial enzymes.  

PubMed

Natural enzymes, exquisite biocatalysts mediating every biological process in living organisms, are able to accelerate the rate of chemical reactions up to 10(19) times for specific substrates and reactions. However, the practical application of enzymes is often hampered by their intrinsic drawbacks, such as low operational stability, sensitivity of catalytic activity to environmental conditions, and high costs in preparation and purification. Therefore, the discovery and development of artificial enzymes is highly desired. Recently, the merging of nanotechnology with biology has ignited extensive research efforts for designing functional nanomaterials that exhibit various properties intrinsic to enzymes. As a promising candidate for artificial enzymes, catalytically active nanomaterials (nanozymes) show several advantages over natural enzymes, such as controlled synthesis in low cost, tunability in catalytic activities, as well as high stability against stringent conditions. In this Account, we focus on our recent progress in exploring and constructing such nanoparticulate artificial enzymes, including graphene oxide, graphene-hemin nanocomposites, carbon nanotubes, carbon nanodots, mesoporous silica-encapsulated gold nanoparticles, gold nanoclusters, and nanoceria. According to their structural characteristics, these enzyme mimics are categorized into three classes: carbon-, metal-, and metal-oxide-based nanomaterials. We aim to highlight the important role of catalytic nanomaterials in the fields of biomimetics. First, we provide a practical introduction to the identification of these nanozymes, the source of the enzyme-like activities, and the enhancement of activities via rational design and engineering. Then we briefly describe new or enhanced applications of certain nanozymes in biomedical diagnosis, environmental monitoring, and therapeutics. For instance, we have successfully used these biomimetic catalysts as colorimetric probes for the detection of cancer cells, nucleic acids, proteins, metal ions, and other small molecules. In addition, we also introduce three exciting advances in the use of efficient modulators on artificial enzyme systems to improve the catalytic performance of existing nanozymes. For example, we report that graphene oxide could serve as a modulator to greatly improve the catalytic activity of lysozyme-stabilized gold nanoclusters at neutral pH, which will have great potential for applications in biological systems. We show that, through the incorporation of modulator into artificial enzymes, we can offer a facile but highly effective way to improve their overall catalytic performance or realize the catalytic reactions that were not possible in the past. We expect that nanozymes with unique properties and functions will attract increasing research interest and lead to new opportunities in various fields of research. PMID:24437921

Strengthening Chronic Disease Prevention Programming: the Toward Evidence-Informed Practice (TEIP) Program Assessment Tool  

PubMed Central

Best practices identified solely on the strength of research evidence may not be entirely relevant or practical for use in community-based public health and the practice of chronic disease prevention. Aiming to bridge the gap between best practices literature and local knowledge and expertise, the Ontario Public Health Association, through the Toward Evidence-Informed Practice initiative, developed a set of resources to strengthen evidence-informed decision making in chronic disease prevention programs. A Program Assessment Tool, described in this article, emphasizes better processes by incorporating review criteria into the program planning and implementation process. In a companion paper, “Strengthening Chronic Disease Prevention Programming: The Toward Evidence-Informed Practice (TEIP) Program Evidence Tool,” we describe another tool, which emphasizes better evidence by providing guidelines and worksheets to identify, synthesize, and incorporate evidence from a range of sources (eg, peer-reviewed literature, gray literature, local expertise) to strengthen local programs. The Program Assessment Tool uses 19 criteria derived from literature on best and promising practices to assess and strengthen program planning and implementation. We describe the benefits, strengths, and challenges in implementing the tool in 22 community-based chronic disease prevention projects in Ontario, Canada. The Program Assessment Tool helps put best processes into operation to complement adoption and adaptation of evidence-informed practices for chronic disease prevention.

Towards practical implementation of bioelectrochemical wastewater treatment.  

PubMed

Bioelectrochemical systems (BESs), such as microbial fuel cells (MFCs) and microbial electrolysis cells (MECs), are generally regarded as a promising future technology for the production of energy from organic material present in wastewaters. The current densities that can be generated with laboratory BESs now approach levels that come close to the requirements for practical applications. However, full-scale implementation of bioelectrochemical wastewater treatment is not straightforward because certain microbiological, technological and economic challenges need to be resolved that have not previously been encountered in any other wastewater treatment system. Here, we identify these challenges, provide an overview of their implications for the feasibility of bioelectrochemical wastewater treatment and explore the opportunities for future BESs.

The Promise and the Problems of Epigenetics Biomarkers in Cancer  

PubMed Central

Epigenetics plays an important role in tissue differentiation and phenotypic changes are associated with extensive modifications in epigenetic patterns such as DNA methylation (DNAme), histone methylation and acetylation marks, and micro RNAs. From a diagnostic perspective, DNAme is one of the more tractable epigenetic changes; differentially affecting a large number of genes. Variations can be measured accurately, on any given set of CG sites, by sequencing bisulfite converted DNA. The promise of DNAme is that biomarkers can be found in every kind of gene from rare unstable cell-cycle enzymes to highly expressed structural proteins. Almost any kind of biological specimen is amenable and the changes can be measured in tissue biopsies, scrapes, aspirates, urine, blood and other fluids. To date, hundreds of differentially methylated genes have been identified in cancer that can potentially function as biomarkers. The most common kind of change, studied, is CpG island methylation of tumor suppressor genes that modifies transcription. Despite a great many candidates, few of the DNAme markers have been adequately validated for routine clinical use. Important current limitations of epigenetic biomarkers are that assays are diverse; gene lists are large; comparative data are few, and disagreements in published papers are frequent.

Lean Premixed Combustion Stabilized by Low Swirl a Promising Concept for Practical Applications  

NASA Technical Reports Server (NTRS)

Since its inception, the low-swirl burner (LSB) has shown to be a useful laboratory apparatus for fundamental studies of premixed turbulent flames. The LSB operates under wide ranges of equivalence ratios, flow rates, and turbulence intensities. Its flame is lifted and detached from the burner and allows easy access for laser diagnostics. The flame brush is axisymmetric and propagates normal to the incident reactants. Therefore, the LSB is well suited for investigating detailed flame structures and empirical coefficients such as flame speed, turbulence transport, and flame generated turbulence. Due to its capability to stabilize ultra-lean premixed turbulent flames (phi approx. = 0.55), the LSB has generated interest from the gas appliance industry for use as an economical low-NO(x) burner. Lean premixed combustion emits low levels of NO(x), due primarily to the low flame temperature. Therefore, it is a very effective NO(x) prevention method without involving selective catalytic reduction (SCR), fuel-air staging, or flue gas recirculation (FGR). En the gas turbine industry, substantial research efforts have already been undertaken and engines with lean premixed combustors are already in use. For commercial and residential applications, premixed pulsed combustors and premixed ceramic matrix burners are commercially available. These lean premixed combustion technologies, however, tend to be elaborate but have relatively limited operational flexibility, and higher capital, operating and maintenance costs. Consequently, these industries are continuing the development of lean premixed combustion technologies as well as exploring new concepts. This paper summarizes the research effects we have undertaken in the past few years to demonstrate the feasibility of applying the low-swirl flame stabilization method for a wide range of heating and power generation systems. The principle of flame stabilization by low-swirl is counter to the conventional high-swirl methods that rely on a recirculation zone to anchor the flame. In LSBS, flow recirculation is not promoted to allow the premixed turbulent flames to propagate freely. A LSB with an air-jet swirler is essentially an open tube with the swirler at its mid section. The small air-jets generate swirling motion only in the annular region and leaving the central core of the flow undisturbed, When this flow exits the burner tube, the angular momentum generates radial mean pressure gradient to diverge the non-swirling reactants stream. Consequently, the mean flow velocity decreases linearly. Propagating against this decelerating flow, the flame self-sustains at the position where the local flow velocity equals the flame speed, S(sub f). The LSB operates with a swirl number, S, between 0.02 to 0.1. This is much lower than the minimum S of 0.6 required for the high-swirl burners. We found that the swirl number needed for flame stabilization varies only slightly with fuel type, flow velocity, turbulent conditions and burner dimensions (i.e. throat diameter and swirl injection angle).

Tidal Volume Single Breath Washout of Two Tracer Gases - A Practical and Promising Lung Function Test  

PubMed Central

Background Small airway disease frequently occurs in chronic lung diseases and may cause ventilation inhomogeneity (VI), which can be assessed by washout tests of inert tracer gas. Using two tracer gases with unequal molar mass (MM) and diffusivity increases specificity for VI in different lung zones. Currently washout tests are underutilised due to the time and effort required for measurements. The aim of this study was to develop and validate a simple technique for a new tidal single breath washout test (SBW) of sulfur hexafluoride (SF6) and helium (He) using an ultrasonic flowmeter (USFM). Methods The tracer gas mixture contained 5% SF6 and 26.3% He, had similar total MM as air, and was applied for a single tidal breath in 13 healthy adults. The USFM measured MM, which was then plotted against expired volume. USFM and mass spectrometer signals were compared in six subjects performing three SBW. Repeatability and reproducibility of SBW, i.e., area under the MM curve (AUC), were determined in seven subjects performing three SBW 24 hours apart. Results USFM reliably measured MM during all SBW tests (n?=?60). MM from USFM reflected SF6 and He washout patterns measured by mass spectrometer. USFM signals were highly associated with mass spectrometer signals, e.g., for MM, linear regression r-squared was 0.98. Intra-subject coefficient of variation of AUC was 6.8%, and coefficient of repeatability was 11.8%. Conclusion The USFM accurately measured relative changes in SF6 and He washout.

Arctic Observing Network Data Management: Current Capabilities and Their Promise for the Future  

NASA Astrophysics Data System (ADS)

CADIS (the Cooperative Arctic Data and Information Service) serves as the data management, discovery and delivery component of the Arctic Observing Network (AON). As an International Polar Year (IPY) initiative, AON comprises 34 land, atmosphere and ocean observation sites, and will acquire much of the data coming from the interagency Study of Environmental Arctic Change (SEARCH). CADIS is tasked with ensuring that these observational data are managed for long term use by members of the entire Earth System Science community. Portions of CADIS are either in use by the community or available for testing. We now have an opportunity to evaluate the feedback received from our users, to identify any design shortcomings, and to identify those elements which serve their purpose well and will support future development. This presentation will focus on the nuts-and-bolts of the CADIS development to date, with an eye towards presenting lessons learned and best practices based on our experiences so far. The topics include: - How did we assess our users' needs, and how are those contributions reflected in the end product and its capabilities? - Why did we develop a CADIS metadata profile, and how does it allow CADIS to support preservation and scientific interoperability? - How can we shield the user from metadata complexities (especially those associated with various standards) while still obtaining the metadata needed to support an effective data management system? - How can we bridge the gap between the data storage formats considered convenient by researchers in the field, and those which are necessary to provide data interoperability? - What challenges have been encountered in our efforts to provide access to federated data (data stored outside of the CADIS system)? - What are the data browsing and visualization needs of the AON community, and which tools and technologies are most promising in terms of supporting those needs? A live demonstration of the current capabilities of the CADIS system will be included as time and logistics allow. CADIS is a joint effort of the University Corporation for Atmospheric Research (UCAR), the National Snow and Ice Data Center (NSIDC), and the National Center for Atmospheric Research (NCAR).

Pthlh, a promising cancer modifier gene in rat tongue carcinogenesis.  

PubMed

Susceptibly to the induction of rat tongue cancer (TC) by oral 4-nitroquinoline 1-oxide (4NQO) exposure is a polygenic trait. Among several quantitative trait loci identified by crosses between TC-susceptible Dark Agouti (DA) rats and TC-resistant Wistar-Furth (WF) rats, we focused on tongue cancer susceptibility locus (Tcas3) of chromosome 4. We examined tongue carcinogenesis in the reciprocal congenic strains DA.WF-Tcas3 and WF.DA-Tcas3 and in their parental strains. The Tcas3DA allele, and not the Tcas3WF allele, significantly favored tumor latency, incidence and TC number/size. In genomic DNA of TCs induced in (DA x WF) F1 rats, the resistant Tcas3WF allele was frequently and selectively lost, particularly in larger tumors. Thus, we searched the possible candidate genes in the Tcas3 region using microarray analysis of TCs in F1 rats and revealed significant upregulation of 2 cancer-related genes, parathyroid hormone-like hormone (Pthlh) and Kras2. The relevance of the WF allele of Pthlh as a cancer modifier was indicated by 3 single nucleotide polymorphisms specific to this strain. In contrast, no consistent strain-specific variations were found in Kras2. Moreover, the plasma Ca2+ level was consistently higher in DA rats when compared to the level in WF rats bearing TCs; moreover, the Pthlh-mRNA expression level was >30-fold higher in TCs when compared to this level in the normal tongue mucosa. Immunostaining experiments showed strong PTHrP protein expression in TCs of DA rats, and the signal was intensified in larger TCs. Kras2 was also upregulated in TCs, but to a lesser degree than PTHrP. Thus, Pthlh is a promising candidate modifier gene in the development and progression of rat TCs. PMID:24253735

Metabolomics tools for identifying biomarkers for neuropsychiatric diseases.  

PubMed

The repertoire of biochemicals (or small molecules) present in cells, tissue, and body fluids is known as the metabolome. Today, clinicians utilize only a very small part of the information contained in the metabolome, as revealed by the quantification of a limited set of analytes to gain information on human health. Examples include measuring glucose or cholesterol to monitor diabetes and cardiovascular health, respectively. With a focus on comprehensively studying the metabolome, the rapidly growing field of metabolomics captures the metabolic state of organisms at the global or "-omics" level. Given that the overall health status of an individual is captured by his or her metabolic state, which is a reflection of what has been encoded by the genome and modified by environmental factors, metabolomics has the potential to have a great impact upon medical practice by providing a wealth of relevant biochemical data. Metabolomics promises to improve current, single metabolites-based clinical assessments by identifying metabolic signatures (biomarkers) that embody global biochemical changes in disease, predict responses to treatment or medication side effects (pharmachometabolomics). State of the art metabolomic analytical platforms and informatics tools are being used to map potential biomarkers for a multitude of disorders including those of the central nervous system (CNS). Indeed, CNS disorders are linked to disturbances in metabolic pathways related to neurotransmitter systems (dopamine, serotonin, GABA and glutamate); fatty acids such as arachidonic acid-cascade; oxidative stress and mitochondrial function. Metabolomics tools are enabling us to map in greater detail perturbations in many biochemical pathways and links among these pathways this information is key for development of biomarkers that are disease-specific. In this review, we elaborate on some of the concepts and technologies used in metabolomics and its promise for biomarker discovery. We also highlight early findings from metabolomic studies in CNS disorders such as schizophrenia, Major Depressive Disorder (MDD), Bipolar Disorder (BD), Amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD).

Gene-alcohol interactions identify several novel blood pressure loci including a promising locus near SLC16A9  

PubMed Central

Alcohol consumption is a known risk factor for hypertension, with recent candidate studies implicating gene-alcohol interactions in blood pressure (BP) regulation. We used 6882 (predominantly) Caucasian participants aged 20–80 years from the Framingham SNP Health Association Resource (SHARe) to perform a genome-wide analysis of SNP-alcohol interactions on BP traits. We used a two-step approach in the ABEL suite to examine genetic interactions with three alcohol measures (ounces of alcohol consumed per week, drinks consumed per week, and the number of days drinking alcohol per week) on four BP traits [systolic (SBP), diastolic (DBP), mean arterial (MAP), and pulse (PP) pressure]. In the first step, we fit a linear mixed model of each BP trait onto age, sex, BMI, and antihypertensive medication while accounting for the phenotypic correlation among relatives. In the second step, we conducted 1 degree-of-freedom (df) score tests of the SNP main effect, alcohol main effect, and SNP-alcohol interaction using the maximum likelihood estimates (MLE) of the parameters from the first step. We then calculated the joint 2 df score test of the SNP main effect and SNP-alcohol interaction using MixABEL. The effect of SNP rs10826334 (near SLC16A9) on SBP was significantly modulated by both the number of alcoholic drinks and the ounces of alcohol consumed per week (p-values of 1.27E-08 and 3.92E-08, respectively). Each copy of the G-allele decreased SBP by 3.79 mmHg in those consuming 14 drinks per week vs. a 0.461 mmHg decrease in non-drinkers. Index SNPs in 20 other loci exhibited suggestive (p-value ? 1E-06) associations with BP traits by the 1 df interaction test or joint 2 df test, including 3 rare variants, one low-frequency variant, and SNPs near/in genes ESRRG, FAM179A, CRIPT-SOCS5, KAT2B, ADCY2, GLI3, ZNF716, SLIT1, PDE3A, KERA-LUM, RNF219-AS1, CLEC3A, FBXO15, and IGSF5. SNP-alcohol interactions may enhance discovery of novel variants with large effects that can be targeted with lifestyle modifications.

Health Literacy Practices and Educational Competencies for Health Professionals: A Consensus Study  

PubMed Central

Health care professionals often lack adequate knowledge about health literacy and the skills needed to address low health literacy among patients and their caregivers. Many promising practices for mitigating the effects of low health literacy are not used consistently. Improving health literacy training for health care professionals has received increasing emphasis in recent years. The development and evaluation of curricula for health professionals has been limited by the lack of agreed-upon educational competencies in this area. This study aimed to identify a set of health literacy educational competencies and target behaviors, or practices, relevant to the training of all health care professionals. The authors conducted a thorough literature review to identify a comprehensive list of potential health literacy competencies and practices, which they categorized into 1 or more educational domains (i.e., knowledge, skills, attitudes) or a practice domain. The authors stated each item in operationalized language following Bloom's Taxonomy. The authors then used a modified Delphi method to identify consensus among a group of 23 health professions education experts representing 11 fields in the health professions. Participants rated their level of agreement as to whether a competency or practice was both appropriate and important for all health professions students. A predetermined threshold of 70% agreement was used to define consensus. After 4 rounds of ratings and modifications, consensus agreement was reached on 62 out of 64 potential educational competencies (24 knowledge items, 27 skill items, and 11 attitude items), and 32 out of 33 potential practices. This study is the first known attempt to develop consensus on a list of health literacy practices and to translate recommended health literacy practices into an agreed-upon set of measurable educational competencies for health professionals. Further work is needed to prioritize the competencies and practices in terms of relative importance.

[Evidence-based and promising interventions to prevent infectious diseases among youth as a result of poor hand hygiene in schools: a literature review].  

PubMed

Infectious diseases remain a major cause of death among young people throughout the world. This paper reviews the current knowledge of empirically validated and promising interventions aimed at preventing infectious diseases among children caused by poor hand hygiene in schools. The study used a standard protocol to identify and review the literature and to classify the selected interventions. Approximately ten interventions were found to have a beneficial effect by promoting hand washing and hand hygiene in schools. The study also found that most of the interventions were implemented at elementary school. However, some interventions were also implemented at kindergarten or in child care centers, while others were aimed at university students. Most of the interventions were implemented by teachers, peers and/or external professionals. The study found that hand hygiene is effective regardless of the type of cleaning product used (i.e. antibacterial or plain soap, alcohol-based or alcohol-free hand sanitizer). This study aims to contribute to the understanding of empirically validated and promising interventions and to promote reflection on professional practice in France. PMID:23782636

Formaldehyde: catalytic oxidation as a promising soft way of elimination.  

PubMed

Compared to other molecules such as benzene, toluene, xylene, and chlorinated compounds, the catalytic oxidation of formaldehyde has been studied rarely. However, standards for the emission level of this pollutant will become more restrictive because of its extreme toxicity even at very low concentrations in air. As a consequence, the development of a highly efficient process for its selective elimination is needed. Complete catalytic oxidation of formaldehyde into CO2 and H2 O using noble-metal-based catalysts is a promising method to convert this pollutant at room temperature, making this process energetically attractive from an industrial point of view. However, the development of a less expensive active phase is required for a large-scale industrial development. Nanomaterials based on oxides of manganese are described as the most promising catalysts. The objective of this Minireview is to present promising recent studies on the removal of formaldehyde through heterogeneous catalysis to stimulate future research in this topic. PMID:23456881

From boots to buoys: promises and challenges of dielectric elastomer energy harvesting  

NASA Astrophysics Data System (ADS)

Dielectric elastomers offer the promise of energy harvesting with few moving parts. Power can be produced simply by stretching and contracting a relatively low-cost rubbery material. This simplicity, combined with demonstrated high energy density and high efficiency, suggests that dielectric elastomers are promising for a wide range of energy harvesting applications. Indeed, dielectric elastomers have been demonstrated to harvest energy from human walking, ocean waves, flowing water, blowing wind, and pushing buttons. While the technology is promising, there are challenges that must be addressed if dielectric elastomers are to be a successful and economically viable energy harvesting technology. These challenges include developing materials and packaging that sustains long lifetime over a range of environmental conditions, design of the devices that stretch the elastomer material, as well as system issues such as practical and efficient energy harvesting circuits. Progress has been made in many of these areas. We have demonstrated energy harvesting transducers that have operated over 5 million cycles. We have also shown the ability of dielectric elastomer material to survive for months underwater while undergoing voltage cycling. We have shown circuits capable of 78% energy harvesting efficiency. While the possibility of long lifetime has been demonstrated at the watt level, reliably scaling up to the power levels required for providing renewable energy to the power grid or for local use will likely require further development from the material through to the systems level.

Xeroradiography: Stagnated after a Promising Beginning? A Historical Review  

PubMed Central

Various methods have been introduced for obtaining radiographs. Xeroradiography which is a method of imaging uses the xeroradiographic copying process to record images produced by diagnostic x-rays. It differs from halide film technique in that it involves neither wet chemical processing nor the use of dark room. Literature on this subject is scarce. After an initial promising beginning, this imaging method, once thought to hold the key to endodontic imaging, got stagnated. A revisit of this promising endodontic imaging system would therefore be appropriate. The purpose of this study was to review xeroradiographic technique as a roentgenographic imaging system.

Identifying broadcast content  

US Patent & Trademark Office Database

In a broadcast system (210) each broadcast content item is identified by a broadcast Content Reference Identifier (CRID). In a storage device (220) with a storage (240) each broadcast content item is identified by a local CRID. A processor (230) stores a CRID list that includes for CRIDs an associated validity interval including a starting date and an ending date during which interval the CRID is unique for the content item. When the processor receives (400) a broadcast CRID, it determines (410) an initial validity interval for the broadcast CRID. The initial validity interval includes a starting date and an ending date during which interval the broadcast CRID is unique for the broadcast content item. It then determines (420) whether the initial validity interval overlaps with a validity interval stored in the CRID list for an identical CRID. If there is no overlap it adds (430) the broadcast CRID to the CRID list.

Translating learning into practice  

PubMed Central

PROBLEM ADDRESSED The need for effective and accessible educational approaches by which family physicians can maintain practice competence in the face of an overwhelming amount of medical information. OBJECTIVE OF PROGRAM The practice-based small group (PBSG) learning program encourages practice changes through a process of small-group peer discussion—identifying practice gaps and reviewing clinical approaches in light of evidence. PROGRAM DESCRIPTION The PBSG uses an interactive educational approach to continuing professional development. In small, self-formed groups within their local communities, family physicians discuss clinical topics using prepared modules that provide sample patient cases and accompanying information that distils the best evidence. Participants are guided by peer facilitators to reflect on the discussion and commit to appropriate practice changes. CONCLUSION The PBSG has evolved over the past 15 years in response to feedback from members and reflections of the developers. The success of the program is evidenced in effect on clinical practice, a large and increasing number of members, and the growth of interest internationally.

Promising pharmacological, molecular and cellular treatments of autoimmune hepatitis.  

PubMed

Current corticosteroid regimens are effective in autoimmune hepatitis, but therapy can be complicated by side effects, disease progression, incomplete response, and relapse after drug withdrawal. The aims of this review are to describe the promising pharmacological, molecular and cellular interventions for autoimmune hepatitis and to stimulate further investigations that can refresh or replace current treatments. Murine models that introduce pertinent human disease-related antigens by vaccination or viral infection promise a resource by which to evaluate new treatments. Promising new drug therapies include the calcineurin-inhibitors (cyclosporine, tacrolimus), next generation purine antagonists (mycophenolate mofetil, 6-thioguanine nucleotides), next generation glucocorticoids (budesonide, deflazacort), and inhibitors of the mammalian target of rapamycin (rapamycin). Feasible molecular interventions are recombinant molecules that affect immune regulatory pathways (cytotoxic T lymphocyte antigen 4, recombinant interleukin 10), monoclonal antibodies that disrupt activation pathways (antibodies to CD3, CD28, CD 20, or tumor necrosis factor-?), and synthetic peptides that block antigen display or promote antigen desensitization (oral tolerance). New methods to stimulate or replenish regulatory T cell populations (adoptive transfer, mesenchymal stem cell or autologous bone marrow transplantation) are feasible as are genetic manipulations (gene silencing) and gene supplementations (gene replacement therapy). The emergence of new therapies for autoimmune hepatitis requires a standardized and universalized animal model of the human disease, consensus regarding the most promising modality to be tested, and formation of a cooperative international network of committed clinical investigators to evaluate new therapies in a pre-designed rigorous yet expeditious fashion.

Transcendent professionalism: keeping promises and living the questions.  

PubMed

Wynia and colleagues propose a definition of professionalism as a belief system by which to shape health care rather than a list of values and behaviors. The belief that professionalism is the best way to organize and deliver health care constitutes a promise to society. The notion that the medical profession as a whole as well as its individual members should be held accountable to standards of competence, ethical values, and interpersonal attributes developed, declared, and enforced by the profession itself is also a promise to society. The author argues that good promises offer a stabilizing influence over the inherent uncertainty in human relationships and may provide the ground for a lasting trustworthy relationship between the medical profession and society; however, the professionalism belief system itself is vulnerable if the promise is breached. The modern world has challenged the professionalism model of organizing health care, and individual practitioners as well as their professional organizations are seeking clarity about what professionalism means given current realities. This commentary reflects on these circumstances and provides some recommendations for developing a construct of professionalism. PMID:24667519

How to identify the genetic basis of gastrointestinal and liver diseases?  

PubMed Central

New insights into the genetic basis of disease are being generated at an ever increasing rate. This explosion of information was ignited by technological advances, such as the polymerase chain reaction and automated DNA sequencing. Although its promise is great, the integration of genetics into the everyday practice of medicine remains challenging. This review discusses the application of molecular genetics in general with a specific focus on hereditary diseases of the digestive organs. The application of molecular genetics in everyday clinical routine is hampered by the difficult interpretation of test results. These difficulties include the prediction of disease penetrance, the presence of multiple mutations of a particular gene with varying functional consequences, and the importance of exogenous factors modulating disease expression. To date, the most significant impact of genetics has been to increase our understanding of disease aetiology and pathogenesis and to reliably identify siblings of affected patients with the risk to develop symptomatic disease.

On identified predictive control  

NASA Technical Reports Server (NTRS)

Self-tuning control algorithms are potential successors to manually tuned PID controllers traditionally used in process control applications. A very attractive design method for self-tuning controllers, which has been developed over recent years, is the long-range predictive control (LRPC). The success of LRPC is due to its effectiveness with plants of unknown order and dead-time which may be simultaneously nonminimum phase and unstable or have multiple lightly damped poles (as in the case of flexible structures or flexible robot arms). LRPC is a receding horizon strategy and can be, in general terms, summarized as follows. Using assumed long-range (or multi-step) cost function the optimal control law is found in terms of unknown parameters of the predictor model of the process, current input-output sequence, and future reference signal sequence. The common approach is to assume that the input-output process model is known or separately identified and then to find the parameters of the predictor model. Once these are known, the optimal control law determines control signal at the current time t which is applied at the process input and the whole procedure is repeated at the next time instant. Most of the recent research in this field is apparently centered around the LRPC formulation developed by Clarke et al., known as generalized predictive control (GPC). GPC uses ARIMAX/CARIMA model of the process in its input-output formulation. In this paper, the GPC formulation is used but the process predictor model is derived from the state space formulation of the ARIMAX model and is directly identified over the receding horizon, i.e., using current input-output sequence. The underlying technique in the design of identified predictive control (IPC) algorithm is the identification algorithm of observer/Kalman filter Markov parameters developed by Juang et al. at NASA Langley Research Center and successfully applied to identification of flexible structures.

Students work with real data on shoe length, height, and gender to develop the model. Students write a report to the crime victim that identifies a suspect and justifies their decision. The activity sets the stage for students to learn about regression models, and reinforces their understanding of central tendency and variability. It is suggested that this activity be used prior to a formal introduction to linear relationships.

Strengthening Chronic Disease Prevention Programming: The Toward Evidence-Informed Practice (TEIP) Program Evidence Tool  

PubMed Central

In public health and chronic disease prevention there is increasing priority for effective use of evidence in practice. In Ontario, Canada, despite various models being advanced, public health practitioners are seeking ways to identify and apply evidence in their work in practical and meaningful ways. In a companion article, “Strengthening Chronic Disease Prevention Programming: The Toward Evidence-Informed Practice (TEIP) Program Assessment Tool,” we describe use of a tool to assess and strengthen program planning and implementation processes using 19 criteria derived from best and promising practices literature. In this article, we describe use of a complementary Program Evidence Tool to identify, synthesize, and apply a range of evidence sources to strengthen the content of chronic disease prevention programming. The Program Evidence Tool adapts tools of evidence-based medicine to the unique contexts of community-based health promotion and chronic disease prevention. Knowledge management tools and a guided dialogue process known as an Evidence Forum enable community stakeholders to make appropriate use of evidence in diverse social, political, and structural contexts. Practical guidelines and worksheets direct users through 5 steps: 1) define an evidence question, 2) develop a search strategy, 3) collect and synthesize evidence, 4) interpret and adapt evidence, and 5) implement and evaluate. We describe the Program Evidence Tool’s benefits, strengths, challenges, and what was learned from its application in 4 Ontario public health departments. The Program Evidence Tool contributes to the development and understanding of the complex use of evidence in community-based chronic disease prevention.

Toward cardiovascular MRI at 7 T: clinical needs, technical solutions and research promises  

PubMed Central

Objective To consider potential clinical needs, technical solutions and research promises of ultrahigh-field strength cardiovascular MR (CMR). Methods A literature review is given, surveying advantages and disadvantages of CMR at ultrahigh fields (UHF). Key concepts, emerging technologies, practical considerations and applications of UHF CMR are provided. Examples of UHF CMR imaging strategies and their added value are demonstrated, including the numerous unsolved problems. A concluding section explores future directions in UHF CMR. Results UHF CMR can be regarded as one of the most challenging MRI applications. Image quality achievable at UHF is not always exclusively defined by signal-to-noise considerations. Some of the inherent advantages of UHF MRI are offset by practical challenges. But UHF CMR can boast advantages over its kindred lower field counterparts by trading the traits of high magnetic fields for increased temporal and/or spatial resolution. Conclusions CMR at ultrahigh-field strengths is a powerful motivator, since speed and signal may be invested to overcome the fundamental constraints that continue to hamper traditional CMR. If practical challenges can be overcome, UHF CMR will help to open the door to new approaches for basic science and clinical research.

IDENTIFYING COLLISIONAL FAMILIES IN THE KUIPER BELT  

SciTech Connect

The identification and characterization of numerous collisional families-clusters of bodies with a common collisional origin-in the asteroid belt has added greatly to the understanding of asteroid belt formation and evolution. More recent study has also led to an appreciation of physical processes that had previously been neglected (e.g., the Yarkovsky effect). Collisions have certainly played an important role in the evolution of the Kuiper Belt as well, though only one collisional family has been identified in that region to date, around the dwarf planet Haumea. In this paper, we combine insights into collisional families from numerical simulations with the current observational constraints on the dynamical structure of the Kuiper Belt to investigate the ideal sizes and locations for identifying collisional families. We find that larger progenitors (r {approx} 500 km) result in more easily identifiable families, given the difficulty in identifying fragments of smaller progenitors in magnitude-limited surveys, despite their larger spread and less frequent occurrence. However, even these families do not stand out well from the background. Identifying families as statistical overdensities is much easier than characterizing families by distinguishing individual members from interlopers. Such identification seems promising, provided the background population is well known. In either case, families will also be much easier to study where the background population is small, i.e., at high inclinations. Overall, our results indicate that entirely different techniques for identifying families will be needed for the Kuiper Belt, and we provide some suggestions.

Hombres Sanos: Evaluation of a Social Marketing Campaign for Heterosexually Identified Latino Men Who Have Sex With Men and Women  

PubMed Central

Objectives. We evaluated the effectiveness of Hombres Sanos [Healthy Men] a social marketing campaign to increase condom use and HIV testing among heterosexually identified Latino men, especially among heterosexually identified Latino men who have sex with men and women (MSMW). Methods. Hombres Sanos was implemented in northern San Diego County, California, from June 2006 through December 2006. Every other month we conducted cross-sectional surveys with independent samples of heterosexually identified Latino men before (n = 626), during (n = 752), and after (n = 385) the campaign. Respondents were randomly selected from 12 targeted community venues to complete an anonymous, self-administered survey on sexual practices and testing for HIV and other sexually transmitted infections. About 5.6% of respondents (n = 98) were heterosexually identified Latino MSMW. Results. The intervention was associated with reduced rates of recent unprotected sex with both females and males among heterosexually identified Latino MSMW. The campaign was also associated with increases in perception of HIV risk, knowledge of testing locations, and condom carrying among heterosexual Latinos. Conclusions. Social marketing represents a promising approach for abating HIV transmission among heterosexually identified Latinos, particularly for heterosexually identified Latino MSMW. Given the scarcity of evidence-based HIV prevention interventions for these populations, this prevention strategy warrants further investigation.

List identifies threatened ecosystems  

NASA Astrophysics Data System (ADS)

The International Union for Conservation of Nature (IUCN) announced on 9 September that it will develop a new Red List of Ecosystems that will identify which ecosystems are vulnerable or endangered. The list, which is modeled on the group's Red List of Threatened Species™, could help to guide conservation activities and influence policy processes such as the Convention on Biological Diversity, according to the group. “We will assess the status of marine, terrestrial, freshwater, and subterranean ecosystems at local, regional, and global levels,” stated Jon Paul Rodriguez, leader of IUCN's Ecosystems Red List Thematic Group. “The assessment can then form the basis for concerted implementation action so that we can manage them sustainably if their risk of collapse is low or restore them if they are threatened and then monitor their recovery.”

Establishing a group practice "without walls".  

PubMed

The group practice "without walls" has become a health care delivery system that is preferred by an increasing number of physicians. This article traces the experience of Premier Medical Group, PC, a "second generation" clinic without walls in the Denver Metropolitan area, to highlight the potential benefits and the key issues related to the development and implementation of a group practice-without-walls model of health-care delivery. The model promises to address physician business and professional needs by building on the best aspects of a traditional group practice, in an overall organizational structure that maximizes each physician's autonomy, individual practice style, and practice identity. The successful implementation of a group practice without walls depends upon physician leadership and impetus, clear goals-and-objectives, competent professional staff, and legal-and-financial guidance.

Identifying risk: the limitations of incident reporting.  

PubMed

Incident reporting is considered an important source of risk management data for identifying and addressing the causes of errors that occur in health-care organizations. However, the effectiveness of incident reporting in accurately identifying risk may be influenced by variables in the structure and design of incident reporting systems. Several variables, including data bias, system usability, non-standardized terminology and coding, and deficiencies in combined data analysis can reduce risk data accuracy. Until incident reporting systems are enhanced and an environment of safety is promoted, incident reports can provide only a glimmer of insight into organizational risk and quality improvement. Practice environments that support shared decision-making and collaborative care teams and provide stimulating learning opportunities can enhance professional nursing practice and inspire a culture of patient safety.

Using EHRs to integrate research with patient care: promises and challenges  

PubMed Central

Clinical research is the foundation for advancing the practice of medicine. However, the lack of seamless integration between clinical research and patient care workflow impedes recruitment efficiency, escalates research costs, and hence threatens the entire clinical research enterprise. Increased use of electronic health records (EHRs) holds promise for facilitating this integration but must surmount regulatory obstacles. Among the unintended consequences of current research oversight are barriers to accessing patient information for prescreening and recruitment, coordinating scheduling of clinical and research visits, and reconciling information about clinical and research drugs. We conclude that the EHR alone cannot overcome barriers in conducting clinical trials and comparative effectiveness research. Patient privacy and human subject protection policies should be clarified at the local level to exploit optimally the full potential of EHRs, while continuing to ensure participant safety. Increased alignment of policies that regulate the clinical and research use of EHRs could help fulfill the vision of more efficiently obtaining clinical research evidence to improve human health.

MHD/steam electrical power production - Promise, progress and problems  

NASA Astrophysics Data System (ADS)

The MHD/Steam Power Plant has promise to burn coal and produce electrical power more efficiently than conventional coal fired plants while producing less environmental intrusion. Problems have been encountered in developing a high temperature air heater (HTAH) using coal exhaust products. Early commercial plants have been proposed that use either a gasifier to produce clean fuel for a separately fired HTAH or use oxygen enrichment to avoid the need for a HTAH. Component development is progressing rapidly but test data is needed at intermediate sizes before a commercial plant can be designed with high confidence of success. Related commercial technology is being adapted for the steam bottoming plant.

A series of cinnamic acid conjugates of primaquine and chloroquine were evaluated for their in vitro antileishmanial activities. Although primaquine derivatives had modest activity, chloroquine conjugates exhibited potent activity against both promastigotes (50% inhibitory concentration [IC50] = 2.6 to 21.8 ?M) and intramacrophagic amastigotes (IC50 = 1.2 to 9.3 ?M) of Leishmania infantum. Both the high activity of these chloroquine analogues and their mild-to-low toxicity toward host cells make them promising leads for the discovery of new antileishmanial agents.

Identifying Adolescent Sleep Problems  

PubMed Central

Objectives To examine the efficacy of self-report and parental report of adolescent sleep problems and compare these findings to the incidence of adolescents who fulfill clinical criteria for a sleep problem. Sleep and daytime functioning factors that predict adolescents’ self-identification of a sleep problem will also be examined. Method 308 adolescents (aged 13–17 years) from eight socioeconomically diverse South Australian high schools participated in this study. Participants completed a survey battery during class time, followed by a 7-day Sleep Diary and the Flinders Fatigue Scale completed on the final day of the study. Parents completed a Sleep, Medical, Education and Family History Survey. Results The percentage of adolescents fulfilling one or more of the criteria for a sleep problem was inordinately high at 66%. Adolescent self-reporting a sleep problem was significantly lower than the adolescents who had one or more of the clinical criteria for a sleep problem (23.1% vs. 66.6%; ?2?=?17.46, p<.001). Parental report of their adolescent having a sleep problem was significantly lower than adolescent self-report (14.3% vs. 21.1%, p<.001). Adolescents who reported unrefreshing sleep were 4.81 times more likely to report a sleep problem. For every hour that bedtime was delayed, the odds of self-reporting a sleep problem increased by 1.91 times, while each additional 10 minutes taken to fall asleep increased the odds 1.40 times. Conclusion While many adolescents were found to have sleep patterns indicative of a sleep problem, only a third of this number self-identify having a sleep problem, while only a sixth of this number are indicated by parental report. This study highlights important features to target in future sleep education and intervention strategies for both adolescents and parents.

Evaluation of Patient Centered Medical Home Practice Transformation Initiatives  

PubMed Central

Background The patient-centered medical home (PCMH) has become a widely cited solution to the deficiencies in primary care delivery in the United States. To achieve the magnitude of change being called for in primary care, quality improvement interventions must focus on whole-system redesign, and not just isolated parts of medical practices. Methods Investigators participating in 9 different evaluations of Patient Centered Medical Home implementation shared experiences, methodological strategies, and evaluation challenges for evaluating primary care practice redesign. Results A year-long iterative process of sharing and reflecting on experiences produced consensus on 7 recommendations for future PCMH evaluations: (1) look critically at models being implemented and identify aspects requiring modification; (2) include embedded qualitative and quantitative data collection to detail the implementation process; (3) capture details concerning how different PCMH components interact with one another over time; (4) understand and describe how and why physician and staff roles do, or do not evolve; (5) identify the effectiveness of individual PCMH components and how they are used; (6) capture how primary care practices interface with other entities such as specialists, hospitals, and referral services; and (7) measure resources required for initiating and sustaining innovations. Conclusions Broad-based longitudinal, mixed-methods designs that provide for shared learning among practice participants, program implementers, and evaluators are necessary to evaluate the novelty and promise of the PCMH model. All PCMH evaluations should as comprehensive as possible, and at a minimum should include a combination of brief observations and targeted qualitative interviews along with quantitative measures.

Restaurant food cooling practices.  

PubMed

Improper food cooling practices are a significant cause of foodborne illness, yet little is known about restaurant food cooling practices. This study was conducted to examine food cooling practices in restaurants. Specifically, the study assesses the frequency with which restaurants meet U.S. Food and Drug Administration (FDA) recommendations aimed at reducing pathogen proliferation during food cooling. Members of the Centers for Disease Control and Prevention's Environmental Health Specialists Network collected data on food cooling practices in 420 restaurants. The data collected indicate that many restaurants are not meeting FDA recommendations concerning cooling. Although most restaurant kitchen managers report that they have formal cooling processes (86%) and provide training to food workers on proper cooling (91%), many managers said that they do not have tested and verified cooling processes (39%), do not monitor time or temperature during cooling processes (41%), or do not calibrate thermometers used for monitoring temperatures (15%). Indeed, 86% of managers reported cooling processes that did not incorporate all FDA-recommended components. Additionally, restaurants do not always follow recommendations concerning specific cooling methods, such as refrigerating cooling food at shallow depths, ventilating cooling food, providing open-air space around the tops and sides of cooling food containers, and refraining from stacking cooling food containers on top of each other. Data from this study could be used by food safety programs and the restaurant industry to target training and intervention efforts concerning cooling practices. These efforts should focus on the most frequent poor cooling practices, as identified by this study. PMID:23212014

Predicting sudden cardiac death from T wave alternans of the surface electrocardiogram: promise and pitfalls  

NASA Technical Reports Server (NTRS)

Sudden cardiac death remains a preeminent public health problem. Despite advances in preventative treatment for patients known to be at risk, to date we have been able to identify, and thus treat, only a small minority of these patients. Therefore, there is a major need to develop noninvasive diagnostic technologies to identify patients at risk. Recent studies have demonstrated that measurement of microvolt-level T wave alternans is a promising technique for the accurate identification of patients at risk for ventricular arrhythmias and sudden cardiac death. In this article, we review the clinical data establishing the relationship between microvolt T wave alternans and susceptibility to ventricular arrhythmias. We also review the methods and technology that have been developed to measure microvolt levels of T wave alternans noninvasively in broad populations of ambulatory patients. In particular, we examine techniques that permit the accurate measurement of T wave alternans during exercise stress testing.

Emerging cancer vaccines: the promise of genetic vectors.  

PubMed

Therapeutic vaccination against cancer is an important approach which, when combined with other therapies, can improve long-term control of cancer. In fact, the induction of adaptive immune responses against Tumor Associated Antigens (TAAs) as well as innate immunity are important factors for tumor stabilization/eradication. A variety of immunization technologies have been explored in last decades and are currently under active evaluation, such as cell-based, protein, peptide and heat-shock protein-based cancer vaccines. Genetic vaccines are emerging as promising methodologies to elicit immune responses against a wide variety of antigens, including TAAs. Amongst these, Adenovirus (Ad)-based vectors show excellent immunogenicity profile and have achieved immunological proof of concept in humans. In vivo electroporation of plasmid DNA (DNA-EP) is also a desirable vaccine technology for cancer vaccines, as it is repeatable several times, a parameter required for the long-term maintenance of anti-tumor immunity. Recent findings show that combinations of different modalities of immunization (heterologous prime/boost) are able to induce superior immune reactions as compared to single-modality vaccines. In this review, we will discuss the challenges and requirements of emerging cancer vaccines, particularly focusing on the genetic cancer vaccines currently under active development and the promise shown by Ad and DNA-EP heterologous prime-boost.

Cancer immunotherapy: accomplishments to date and future promise.  

PubMed

Cancer remains a devastating disease as existing therapies are too often ineffective and toxicities remain unacceptably high. Immunotherapies for cancer offer the promise of the specificity and memory of the immune system against malignant cells to achieve durable cure with minimal toxicity. Beginning with the success of bone marrow transplantation for blood-borne cancers, and the more recent development of monoclonal antibody therapeutics for a variety of tumors, immunotherapies are already among the most successful class of treatments for cancer. Greater understanding of immunoregulatory mechanisms and improved techniques for immune cell manipulation and engineering have led to new immunomodulatory approaches and cell-based therapies for cancer that have generated great excitement within the biomedical community. As these technologies continue to improve, and as new approaches for harnessing the power and specificity of the immune system are developed, immunotherapies will play an increasingly important role in the treatment of cancer. Here, we review the history of immunotherapies for cancer and discuss existing and emerging immunotherapy technologies that hope to translate the promise of immunotherapy into clinical reality.

Public health's promise for the future: 1989 Presidential address  

SciTech Connect

Public health's promise for the future is inextricably related to efforts which maximize human potential and which realize the world's interdependence. Public health challenges are not only constant and complex but frequently surrounded by political activities. In this environment, the public health enterprise has been enhanced by the Institute of Medicine, National Academy of Sciences' report on The Future of Public Health and the assessment framework it provides. Risk reduction through preventive and health promotion activities is the primary focus of public health, but facilitation is often dependent upon society's understanding and willingness-to-pay for such services. The effectiveness of public health is related to an ability to coordinate public and private efforts at national, state, and local levels. Also in this environment, public health is empowered through its multidisciplinary approach. However, epidemiology provides a unifying framework for the collective public health effort. Based on the use of epidemiology, public health is empowered to make the argument for a national health program and to support the concept of health as a determinant of life options. Public health's promise for the future can be fulfilled by continuing to increase its scientific base for decision-making, by self-examination and correction, by advocating and promoting self-examination and correction, by advocating and promoting social justice and by promoting firm partnerships with the public.

Clinical practice  

PubMed Central

The most important goal of introducing noninvasive ventilation (NIV) has been to decrease the need for intubation and, therefore, mechanical ventilation in newborns. As a result, this technique may reduce the incidence of bronchopulmonary dysplasia (BPD). In addition to nasal CPAP, improvements in sensors and flow delivery systems have resulted in the introduction of a variety of other types of NIV. For the optimal application of these novelties, a thorough physiological knowledge of mechanics of the respiratory system is necessary. In this overview, the modern insights of noninvasive respiratory therapy in newborns are discussed. These aspects include respiratory support in the delivery room; conventional and modern nCPAP; humidified, heated, and high-flow nasal cannula ventilation; and nasal intermittent positive pressure ventilation. Finally, an algorithm is presented describing common practice in taking care of respiratory distress in prematurely born infants.

EZID: Long term identifiers made easy (Invited)  

NASA Astrophysics Data System (ADS)

Scholarly research is producing ever increasing amounts of digital research data, and this data should be managed throughout the research life cycle both as part of good scientific practice, but also to comply with funder mandates, such as the 2013 OSTP Public Access Memo (http://www.whitehouse.gov/sites/default/files/microsites/ostp/ostp_public_access_memo_2013.pdf). By assigning unique and persistent identifiers to data objects, data managers can gain control and flexibility over what can be a daunting task. This is due to the fact that the objects can be moved to new locations without disruption to links, as long as the identifier target is maintained. EZID is a tool that makes assigning and maintaining unique, persistent identifiers easy. It was designed and built by California Digital Library (CDL) and has both a user interface and a RESTful API. EZID currently offers services for two globally unique, persistent identifier schemes: Digital Object Identifiers (DOIs) and Archival Resource Keys (ARKs). DOIs are identifiers originating from the publishing world and are in widespread use for journal articles. CDL is able to offer DOIs because of being a founding member of DataCite (http://www.datacite.org/), an international consortium established to provide easier access to scientific research data on the Internet. ARKs are identifiers originating from the library, archive and museum community. Like DOIs, they become persistent when the objects and identifier forwarding information is maintained. DOIs and ARKs have a key role in data management and, therefore, in data management plans. DOIs are the recommended identifier for use in data citation, and ARKs provide the maximum flexibility needed for data documentation and management throughout the early phases of a project. The two identifier schemes are able to be used together, and EZID is made to work with both. EZID clients, coming from education, research, government, and the private sector, are utilizing the tool for these use cases and more.

Preparing Mathematics and Science Teachers for Diverse Classrooms: Promising Strategies for Transformative Pedagogy  

NSDL National Science Digital Library

This book provides a theoretical basis and practical strategies to counter resistance to learning to teach for diversity (in culturally and gender-inclusive ways), and resistance to teaching for understanding (using student-centered and inquiry-based pedagogical approaches). Teacher educators from across the United States present rich narratives of their experiences in helping prospective and practicing teachers learn to teach for diversity and for understanding in a variety of mathematics and science contexts. Mathematics and science education has been slow to respond to issues of diversity and equity. Preparing Mathematics and Science Teachers for Diverse Classrooms: Promising Strategies for Transformative Pedagogy helps to begin a network for support and collaboration among teacher educators in science and mathematics who work for multicultural education and equity. A unique and much-needed contribution, this book is an essential resource for teacher educators, K-12 teachers who work as student teacher supervisors and cooperating teachers, and graduate students in mathematics and science education, and a compelling text for science and mathematics methods courses.

Omics approaches in food safety: fulfilling the promise?  

PubMed

Genomics, transcriptomics, and proteomics are rapidly transforming our approaches to the detection, prevention, and treatment of foodborne pathogens. Microbial genome sequencing in particular has evolved from a research tool into an approach that can be used to characterize foodborne pathogen isolates as part of routine surveillance systems. Genome sequencing efforts will not only improve outbreak detection and source tracking, but will also create large amounts of foodborne pathogen genome sequence data, which will be available for data-mining efforts that could facilitate better source attribution and provide new insights into foodborne pathogen biology and transmission. Although practical uses and application of metagenomics, transcriptomics, and proteomics data and associated tools are less prominent, these tools are also starting to yield practical food safety solutions.

They are promising candidates for high pressure gas storage and also for conversion or separation of larger molecules, whose size exceeds the pore size of zeolites. The rational strategies for synthesis of mesoporous MOF are outlined and the unambiguous consistent assessment of the surface area of such ultrahighly porous materials, as well as present challenges in the exciting research field, of mesoporous MOFs are discussed. The crystallinity, dynamic properties, functional groups, and wide range tunability render these materials as exceptional solids, but for the implementation in functional devices and even in industrial processes several aspects and effective characteristics (such as volumetric storage capacities, recyclability, mechanical and chemical stability, activation) should be addressed.

Stem cells as promising therapeutic options for neurological disorders.  

PubMed

Due to the limitations of pharmacological and other current therapeutic strategies, stem cell therapies have emerged as promising options for treating many incurable neurologic diseases. A variety of stem cells including pluripotent stem cells (i.e., embryonic stem cells and induced pluripotent stem cells) and multipotent adult stem cells (i.e., fetal brain tissue, neural stem cells, and mesenchymal stem cells from various sources) have been explored as therapeutic options for treating many neurologic diseases, and it is becoming obvious that each type of stem cell has pros and cons as a source for cell therapy. Wise selection of stem cells with regard to the nature and status of neurologic dysfunctions is required to achieve optimal therapeutic efficacy. To this aim, the stem cell-mediated therapeutic efforts on four major neurological diseases, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and stroke, will be introduced, and current problems and future directions will be discussed.

Neuronal Signal Transduction Pathways: Wasteland or the Promised Land?  

NSDL National Science Digital Library

Proteins used in signal transduction pathways are commonly found in different cell types and organs. However, specific proteins whose expression is highly restricted are also utilized for allowing discrete responsiveness to signals that are otherwise ignored by other cells. How the brain uses common and specific signal proteins for communication within and beyond the cerebrum has been an area of intense study. A new book concentrates on the signaling that occurs in the brain under normal and pathological conditions--memory, apoptosis, neurodegeneration, depression, and drug dependence--and is filled with chapters written by experts in neurobiology and neurophysiology. Bryan Roth reviews the book and discusses in detail several chapters that may lead to promising future research.

Pathogenesis and promising non-invasive markers for preeclampsia  

PubMed Central

Preeclampsia is one of the leading causes of maternal mortality/morbidity and preterm delivery in the world, affecting 3% to 5% of pregnant women. The pathophysiology of preeclampsia likely involves both maternal and fetal/placental factors. Abnormalities in the development of placental vessels early in pregnancy may result in placental hypoperfusion, hypoxia, or ischemia. Hypoperfusion, hypoxia, and ischemia are critical components in the pathogenesis of preeclampsia because the hypoperfused placenta transfers many factors into maternal vessels that alter maternal endothelial cell function and lead to the systemic symptoms of preeclampsia. There are several hypotheses to explain the pathogenesis of preeclampsia, including altered angiogenic balance, circulating angiogenic factors (such as marinobufagenin, a bufadienolide trigger), and activation of the renin-angiotensin system. Epigenetically-modified cell-free nucleic acids that circulate in plasma and serum might be novel markers with promising non-invasive clinical applications in the diagnosis of preeclampsia.

Pityriasis rubra pilaris: evolution of challenges in promising treatment options.  

PubMed

Pityriasis rubra pilaris is an uncommon inflammatory dermatosis that is well recognized across the globe. Erythroderma is a common presentation. A precise diagnosis of pityriasis rubra pilaris is based on morphologic features and is classified into 6 types: classic adult onset (type I), atypical adult (type II), classic juvenile (type III), circumscribed juvenile (type IV), atypical juvenile (type V), and human immunodeficiency virus-associated (type VI). Several conventional systemic and/or topical treatments are currently in use. Largely, their results are unsatisfactory and limited by long-term toxicity. The authors investigate the efficacy of a wide spectrum of drugs by examining historical (archive) and promising (modern) treatment modalities for the treatment of pityriasis rubra pilaris.

The promise of the anti-idiotype concept  

PubMed Central

A basic tenet of antibody-based immunity is their specificity to antigenic determinates from foreign pathogen products to abnormal cellular components such as in cancer. However, an antibody has the potential to bind to more than one determinate, be it an antigen or another antibody. These observations led to the idiotype network theory (INT) to explain immune regulation, which has wax and waned in enthusiasm over the years. A truer measure of the impact of the INT is in terms of the ideas that now form the mainstay of immunological research and whose roots are spawned from the promise of the anti-idiotype concept. Among the applications of the INT is understanding the structural implications of the antibody-mediated network that has the potential for innovation in terms of rational design of reagents with biological, chemical, and pharmaceutical applications that underlies concepts of reverse immunology which is highlighted herein.

Prevention of peritoneal adhesions: A promising role for gene therapy  

PubMed Central

Adhesions are the most frequent complication of abdominopelvic surgery, yet the extent of the problem, and its serious consequences, has not been adequately recognized. Adhesions evolved as a life-saving mechanism to limit the spread of intraperitoneal inflammatory conditions. Three different pathophysiological mechanisms can independently trigger adhesion formation. Mesothelial cell injury and loss during operations, tissue hypoxia and inflammation each promotes adhesion formation separately, and potentiate the effect of each other. Studies have repeatedly demonstrated that interruption of a single pathway does not completely prevent adhesion formation. This review summarizes the pathogenesis of adhesion formation and the results of single gene therapy interventions. It explores the promising role of combinatorial gene therapy and vector modifications for the prevention of adhesion formation in order to stimulate new ideas and encourage rapid advancements in this field.

Gene therapy for gastric cancer: Is it promising?  

PubMed Central

Gastric cancer is one of the most common tumors worldwide. The therapeutic outcome of conventional therapies is inefficient. Thus, new therapeutic strategies are urgently needed. Gene therapy is a promising molecular alternative in the treatment of gastric cancer, including the replacement of defective tumor suppressor genes, the inactivation of oncogenes, the introduction of suicide genes, genetic immunotherapy, anti-angiogenetic gene therapy, and virotherapy. Improved molecular biological techniques and a better understanding of gastric carcinogenesis have allowed us to validate a variety of genes as molecular targets for gene therapy. This review provides an update of the new developments in cancer gene therapy, new principles, techniques, strategies and vector systems, and shows how they may be applied in the treatment of gastric cancer.

Scrap tire recycling: Promising high value applications. Final report  

SciTech Connect

Surface modification of scrap tire rubber (rubber particles treated with chlorine gas) show promise for ameliorating the scrap tire problem (the treated rubber can be used as a component in high- performance, expensive polymer systems). The process has been proven in Phase I. Phase II covers market/applications, process development (Forberg-design mixer reactor was chosen), plant design, capital cost estimate, economics environmental/safety/health, and energy impact. Almost of the small amount of chlorine is consumed. The capital costs for a rubber particle treatment facility are attractive, being at least two orders of magnitude less than that of facilities for making new polymer materials. Large volume markets using treated rubber are needed. The amount of scrap rubber available is small compared to the polymers available for replacement. 7 tabs, 16 figs.

Maternal serum alpha-fetoprotein screening: promise not yet fulfilled.  

PubMed

Measurement of alpha fetoprotein (AFP) levels in amniotic fluid has been used as a diagnostic tool for detection of neural tube defects (NTDs) in the fetus. AFP measurement in conjunction with ultrasonography yields a 90% NTD detection rate. The technique is recommended for use in pregnancies known to be at risk of NTDs and as a screening technique for use with 2nd-trimester amniocentesis. In recent years, maternal serum AFP assays have been used for NTD detection. The technique has promise as a diagnostic tool but is not recommended for routine maternal screening. Problems with maternal AFP screening are: 1) the large number of false positive results; 2) lack of general patient and physician education on the screening technique; 3) technical problems related to the assay; 4) inconsistency of assay results from 1 laboratory to another; and 5) the lack of established normal standards for the test.

Alternative variables in drug discovery: promises and challenges.  

PubMed

A number of alternative variables have appeared in the medicinal chemistry literature trying to provide a more rigorous formulation of the guidelines proposed by Lipinski to exclude chemical entities with poor pharmacokinetic properties early in the discovery process. Typically, these variables combine the affinity towards the target with physicochemical properties of the ligand and are named efficiencies or ligand efficiencies. Several formulations have been defined and used by different laboratories with different degrees of success. A unified formulation, ligand efficiency indices, was proposed that included efficiency in two complementary variables (i.e., size and polarity) to map and monitor the drug-discovery process (AtlasCBS). The use of this formulation in combination with an extended multiparameter optimization is presented, with examples, as a promising methodology to optimize the drug-discovery process in the future. Future perspectives and challenges for this approach are also discussed. PMID:24649959

Promising systemic immunotherapies in head and neck squamous cell carcinoma.  

PubMed

Patients with head and neck squamous cell carcinoma (HNSCC) demonstrate poor survival and significant treatment morbidity with standard therapy. The immune profile in HNSCC, whether caused by carcinogen exposure or human papillomavirus (HPV), is notably immunosuppressive. Early clinical trials of immunotherapy in HNSCC were troubled by systemic toxicity or difficulties in local administration. Now, interest in immunotherapy has been revitalized by mechanistic insights into immune evasion by HNSCC, coupled to ongoing development of novel immunotherapies. This review will summarize immune escape mechanisms in HNSCC, namely downregulation of tumor antigen (TA) presentation, aberrant regulation of the signal transducer and activator of transcription (STAT) family, the immunosuppressive cytokine milieu, and dysregulation of immune effector cells. Therapeutic strategies hypothesized to specifically counter HNSCC immunosuppression will then be discussed. We will survey TA- targeted monoclonal antibodies (mAb), including the prototype cetuximab, as well as adjunctive strategies to enhance antibody-dependent cell-mediated cytotoxicity. We will review immunomodulation to restore STAT1/STAT3 activation balance. Examples of mAb therapy to block immunosuppressive cytokines, such as interleukin-6 or VEGF, will be provided. mAbs which release co-inhibitory T cell receptors such as CTLA-4 and PD-1, overexpressed in HNSCC, also hold therapeutic promise. Finally, we will describe principles for therapeutic vaccination in HPV-associated HNSCC, where non-host TAs such as viral oncoproteins represent ideal targets, and HPV-negative HNSCC, where p53 is a promising target. Insights into immunosuppression in HNSCC have elucidated mechanistic targets for immunotherapy. Rational clinical investigation may lead to effective stand alone or combinatorial treatment approaches. PMID:24126223

Identifying influential nodes in complex networks  

NASA Astrophysics Data System (ADS)

Identifying influential nodes that lead to faster and wider spreading in complex networks is of theoretical and practical significance. The degree centrality method is very simple but of little relevance. Global metrics such as betweenness centrality and closeness centrality can better identify influential nodes, but are incapable to be applied in large-scale networks due to the computational complexity. In order to design an effective ranking method, we proposed a semi-local centrality measure as a tradeoff between the low-relevant degree centrality and other time-consuming measures. We use the Susceptible-Infected-Recovered (SIR) model to evaluate the performance by using the spreading rate and the number of infected nodes. Simulations on four real networks show that our method can well identify influential nodes.

Midwives' practices and beliefs about discharging clients from their practice.  

PubMed

Discharging a client from a practice is a choice clinicians may need to make when conflicts arise that cannot be resolved. The legal and ethical considerations before discharging a client are presented. This preliminary survey of 111 certified nurse-midwives was conducted to determine their practices and beliefs about discharging clients. Most (83.7%) participants had discharged five or fewer clients from their practice throughout their careers, including 36.9% who had never discharged a client from their practice. In contrast, 77.5% of participants said that midwives should definitely discharge clients from their practice under some circumstances. Antepartum care was the most frequent period during which clients were discharged, and 59% of those discharged were for noncompliance with the therapeutic regimen, obnoxious or abusive behavior as subjectively identified by the midwife and her colleagues, or failure to keep appointments. When asked why they might not discharge a client from their practice, 60% identified empathy or sympathy for the client as the reason. When asked why they did not discharge clients in the past, 23 (21%) respondents selected "colleagues disagreed" as the reason. PMID:17826709

Cooperative testing of a positive personnel identifier  

SciTech Connect

HEDL has a requirement to ensure the identification of remote computer terminal operators on a real-time nuclear inventory data base. The integrity of this data base depends on input from authorized individuals. Thus, a key to developing such a system is the ability to positively identify people attempting access to the system. Small scale tests of the Identimat 2000T hand geometry unit with an adjusting alogrithm have suggested a promising solution. To prove operational suitability, HEDL, in cooperation with Sandia Laboratories, has designed a large scale test of the Identimat 2000T. Data gathering on error rates, reliability, maintainability, and user acceptance will determine if the Identimat 2000T is suitable for the HEDL application. If proven acceptable, use of the Identimat 2000T can be broadened to many general applications where security information, locations and systems are required.

Evaluation of N,N-dialkylamides as promising process extractants  

NASA Astrophysics Data System (ADS)

Studies carried out at BARC, India on the development of new extractants for reprocessing of spent fuel suggested that while straight chain N,N-dihexyloctanamide (DHOA) is promising alternative to TBP for the reprocessing of irradiated uranium based fuels, branched chain N,N-di(2-ethylhexyl)isobutyramide (D2EHIBA) is suitable for the selective recovery of 233U from irradiated Th. In advanced fuel cycle scenarios, the coprocessing of U/Pu stream appears attractive particularly with respect to development of proliferation resistant technologies. DHOA extracted Pu(IV) more efficiently than TBP, both at trace-level concentration as well as under uranium/plutonium loading conditions. Uranium extraction behavior of DHOA was however, similar to that of TBP during the extraction cycle. Stripping behavior of U and Pu (without any reductant) was better for DHOA than that of TBP. It was observed during batch studies that whereas 99% Pu is stripped in four stages in case of DHOA, only 89% Pu is stripped in case of TBP under identical experimental conditions. DHOA offered better fission product decontamination than that of TBP. GANEX (Group ActiNide EXtraction) and ARTIST (Amide-based Radio-resources Treatment with Interim Storage of Transuranics) processes proposed for actinide partitioning use branched chain amides for the selective extraction of uranium from spent fuel feed solutions. The branched-alkyl monoamide (BAMA) proposed to be used in ARTIST process is N,N-di-(2-ethylhexyl)butyramide (D2EHBA). In this context, the extraction behavior of U(VI) and Pu(IV) were compared using D2EHIBA, TBP, and D2EHBA under similar concentration of nitric acid (0.5 — 6M) and of uranium (0-50g/L). These studies suggested that D2EHIBA is a promising extractant for selective extraction of uranium over plutonium in process streams. Similarly, D2EHIBA offered distinctly better decontamination of 233U over Th and fission products under THOREX feed conditions. The possibility of simultaneous stripping and precipitation of thorium (as oxalate) from loaded organic phase was explored using 0.05M oxalic acid. Ammonium diuranate (ADU) precipitation was performed on the oxalate supernatant for the recovery of uranium. Quantitative recovery (>99.9%) of Th as well as of U was achieved. Radiolytic studies suggested that irradiated DHOA and D2EHIBA behaved better with respect to fission product decontamination as compared to that of TBP.

The social process of escalation: a promising focus for crisis management research  

PubMed Central

Background This study identifies a promising, new focus for the crisis management research in the health care domain. After reviewing the literature on health care crisis management, there seems to be a knowledge-gap regarding organisational change and adaption, especially when health care situations goes from normal, to non-normal, to pathological and further into a state of emergency or crisis. Discussion Based on studies of escalating situations in obstetric care it is suggested that two theoretical perspectives (contingency theory and the idea of failure as a result of incomplete interaction) tend to simplify the issue of escalation rather than attend to its complexities (including the various power relations among the stakeholders involved). However studying the process of escalation as inherently complex and social allows us to see the definition of a situation as normal or non-normal as an exercise of power in itself, rather than representing a putatively correct response to a particular emergency. Implications The concept of escalation, when treated this way, can help us further the analysis of clinical and institutional acts and competence. It can also turn our attention to some important elements in a class of social phenomenon, crises and emergencies, that so far have not received the attention they deserve. Focusing on organisational choreography, that interplay of potential factors such as power, professional identity, organisational accountability, and experience, is not only a promising focus for future naturalistic research but also for developing more pragmatic strategies that can enhance organisational coordination and response in complex events.

Variations in tobacco control in National Dental PBRN practices: the role of patient and practice factors.  

PubMed

We engaged dental practices enrolled in The National Dental Practice-Based Research Network to quantify tobacco screening (ASK) and advising (ADVISE); and to identify patient and practice -characteristics associated with tobacco control. Dental practices (N = 190) distributed patient surveys that measured ASK and ADVISE. Twenty-nine percent of patients were ASKED about tobacco use during visit, 20% were identified as tobacco users, and 41% reported being ADVISED. Accounting for clustering of patients within practices, younger age and male gender were positively associated with ASK and ADVISE. Adjusting for patient age and gender, a higher proportion of non-whites in the practice, preventive services and proportion on public assistance were positively associated with ASK. Proportion of tobac
