  2. [Administrative support for Asperger's syndrome]. (United States)

    Yamaoka, Shu


    In recent years, administrative support for developmental disabilities, such as Asperger's syndrome, has come to be conspicuous with "Law for Supporting Persons with Developmental Disabilities", which went into effect in 2005, and promotion of "Special Support Education". However, these supports are still insufficient, because administrative support for the Asperger's syndrome in Japan, having just started very recently. Developmental disabilities, such as Asperger's syndrome, are by no means mild as disabilities, it is required to fill up administrative support for them from now on.

  7. Administrative support team. A structural innovation. (United States)

    Eichelberger, K M; Bebl, S; Lees, M L; Peterson, S L; Taylor, A N


    In response to societal, organization, and leadership changes, an innovative nursing structure was implemented and evaluated. An administrative support team was developed to provide specialized internal consultation and support to a flattened and decentralized nursing division. The four administrative support team roles provided an organization perspective that ensured constancy of purpose throughout the division. This structural innovation proved to be congruent with nursing shared governance and total quality management initiatives occurring in the organization. Evaluation studies indicated that the model has effectively supported 5 years of continuing organizational change.

  10. Administrators' perspectives of support for elementary science education (United States)

    Hanegan, Nikki Notias

    This investigation examines administrators' perspectives of support for elementary science education through naturalistic inquiry methodologies. Determining how administrators, as instructional leaders, define and demonstrate support for innovative reform in one curriculum area, specifically in science, has a direct impact on teacher effectiveness to implement change and new curricula into classrooms. Six major areas of current literature were reviewed for this study. They were (1) the need for Elementary Science Education, (2) the current status of Elementary Science Education, (3) the need for science professional development, (4) key components for effective professional development implementation, (5) leadership for elementary science education, and (6) administrative support. These critical issues were selected to deepen the understanding and purpose of this study. As a result of emergent interviews, five major themes developed from this study. They are: (1) knowledge of science instruction and implementation, (2) demonstration of administrative leadership to promote science education, (3) providing necessary resources or materials, (4) providing professional development opportunities, and (5) fostering teacher leadership for science instruction. These themes are discussed with supporting evidence from respondent interviews and verified through teacher interviews, newsletters, web sites, school observations, or curriculum sources. Administrative support for elementary science education is defined as action taken to ascertain that students are receiving quality science instruction. Chapter Five includes a discussion on the effectiveness of managers versus leaders in science education reform. Administrators need more direct involvement and participation in professional development aimed at science education to develop leadership skills, science content knowledge, and tools necessary to develop leaders for future district and school planning to implement science

  13. Ethics in Public Administration: Evidence from Slovenia

    Directory of Open Access Journals (Sweden)

    Zlatko NEDELKO


    Full Text Available The main purpose of this paper is to examine how employees’ personal ethics, expressed through their personal values and attitudes toward social and environmental issues, are associated with the ethics of organizations in public administration. The authors introduce their own theoretical model that examines the relations between employees’ personal ethics – expressed through employees’ personal values and attitudes toward natural and social environments – and the ethics of public administration. The reported study examined these relations and tested a proposed model based on the answers of 212 employees from public administration organizations in Slovenia. Employees’ attitudes toward natural and social environments and the ethics of their organizations were measured using a questionnaire designed to measure aspects of ethics whereas personal values were measured using the Schwartz value survey. The results demonstrated that employees’ self-enhancing values significantly influence their attitudes toward the natural environment. Employees’ self-transcendence and self-enhancement values significantly influence their attitudes toward the social environment and the ethics of organizations. In addition, research results about the mediation effect of employees’ attitudes toward natural and social environments on the association between the employees’ personal values and their perception of the ethics of public administration organizations reveals that employees’ social attitudes have a significant impact on the ethics of public administration while the impact of self-transcending and self-enhancing values becomes insignificant. Based on results of testing our model we can conclude that the employee’s attitudes toward to the social environment represent a significantly more powerful predictor of ethics in public administration organizations than the employees’ personal values. These results present a solid basis for further

  1. Current evidence supporting "letrozole" for ovulation induction

    Directory of Open Access Journals (Sweden)

    Sujata Kar


    Full Text Available Aromatase inhibitor "letrozole" was first introduced as a potential ovulation induction (OI drug almost a decade back. Large number of studies has been published using letrozole for OI: In polycystic ovary syndrome (PCOS women, clomiphene citrate (CC resistant women, for intrauterine insemination and also in various protocols of mild stimulation for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI. Letrozole appears to be a good option, with its oral route of administration, cost, shorter half-life and negligible side effects. However, the verdict on efficacy and safety of letrozole is still uncertain. This review explores the current scientific data supporting letrozole for OI.

  3. Sublingual administration of tacrolimus: current trends and available evidence. (United States)

    Doligalski, Christina Teeter; Liu, Esther C; Sammons, Chelsea M; Silverman, Andrew; Logan, Angela Tong


    Widespread anecdotal use of sublingual tacrolimus administration has arisen, although little literature exists to guide practice. Given the paucity of data, we conducted a survey to evaluate the practice of sublingual tacrolimus administration at transplant centers across the United States and evaluated the literature that is currently available. A 10-question online survey assessing the current state of sublingual tacrolimus use was distributed to pharmacists at transplant centers that each performed more than 100 solid organ transplantations in 2013. In addition, a literature review was performed by searching the PubMed database to identify available evidence for the sublingual administration of tacrolimus. The online survey was completed by 59 (65.6%) of the 90 targeted transplant centers, representing 51.3% of all solid organ transplantations performed in 2013. Sublingual administration of tacrolimus was used in all solid organ transplant populations, with ~67% of lung transplant centers using this route for tacrolimus. The most common dose conversion was 2 mg oral to 1 mg sublingual, with 92% of centers opening oral capsules and administering the contents sublingually. Home use of sublingual administration and use in the pediatric population was uncommon. Seven peer-reviewed reports and one abstract were identified in the literature review. Seven of the eight publications reported favorably on sublingual administration, although no consistent dose conversion or method of administration was elucidated. The majority of the transplant centers surveyed found sublingual tacrolimus a viable alternative when oral administration is unavailable. A large robust prospective evaluation of sublingual administration of tacrolimus is imperative to provide the most effective care to solid organ transplant recipients and to ensure optimal safety for both patients and providers who administer the drug.

  4. Administrative support of novice science teachers: A multiple case study (United States)

    Iacuone, Leann

    Novice science teachers leave the confines of colleges and universities to embark on a new adventure in education where they aim to influence young minds, make a difference in the world, and share their love for their content. They have learned their pedagogical skills with the support and assistance of fellow classmates, a supporting professor, and a cooperating teacher. These teachers enter their new place of employment and are met with many unexpected challenges, such as a lack of resources, no one to ask questions of, and a busy staff with already established relationships, causing them to feel an overall lack of support and resulting in many new teachers rethinking their career choice and leaving the field of education within 5 years of entering. This multiple-case study investigated the administrative support 4 novice science teachers received during an academic year and the novice teachers' perceptions of the support they received to answer the following research question: How do novice science teachers who have consistent interactions with administrators develop during their first year? To answer this question, semistructured interviews, reflection journals, observations, resumes, long-range plans, and student discipline referrals were collected. The findings from this study show novice science teachers who had incidents occur in the classroom requiring administrative assistance and guidance felt more confident in enforcing their classroom management policies and procedures as the year progressed to change student behavior. The novice science teachers perceived administrators who provided resources including technology, office supplies, science supplies, and the guidance of a mentor as supportive. Novice science teachers who engaged in dialogue after administrative observations, were provided the opportunity to attend professional development outside the district, and had a mentor who taught the same discipline made more changes to their instructional

  5. Transforming administration to support science in the schoolhouse for students with disabilities. (United States)

    Boscardin, Mary Lynn


    I examine the role that administrators play in facilitating the development, adoption, use, and evaluation of scientifically based interventions within the school culture to support the educational outcomes of students with learning disabilities (LD). Two ways of transforming the administrative role to support science in the schoolhouse are presented; one considers the importance of including language in future legislation that acknowledges the role of administrators in school reform, and the other focuses on establishing a national research agenda addressing issues of leadership and special education. I argue that these 2 venues should serve to identify and to stimulate the use of evidence-based administrative practices that ultimately increase educational outcomes for students with LD, improve teacher instruction, and transform the leadership mission.

  6. Biochemical evidence supporting the Cortina criteria. (United States)

    von Werder, K


    Whether acromegaly is inactive or active, respectively cured or not cured depends on the GH suppressibility and the basal IGF-I level. According to the Cortina criteria, GH suppression after oral ingestion of 75 g glucose to acromegaly. According to more recent publications, mortality, which is increased in active acromegaly, is normalized when GH and IGF-I levels have become normal as defined above. Morbidity, i.e. typical features of acromegaly like cardiac problems, carpal tunnel syndrome, carbohydrate intolerance, and excessive sweating may also improve though painful arthropathy, and coarse facial features usually remain unaltered even if the biochemistry has been completely normalized. Using more sensitive GH assays, a group of acromegalic patients was shown to have normal IGF-I levels after surgery, with post-glucose levels of GH 0.14 microg/l, which is the upper level of normal subjects and of a second group of successfully operated acromegalic patients. The latter group also had slightly lower IGF-I levels, though such levels were normal in both groups. Whether this may indicate that these patients who have higher GH levels after oral glucose measured with the more sensitive immunoradiometric assay (IRMA) will more likely develop recurrences remains to be demonstrated in a larger cohort. According to the criteria put forward in Cortina d'Ampezzo in February 1999, all patients who have post-glucose GH levels <1 microg/l and normal age-matched IGF-I levels have to be regarded as well controlled, i.e. sufficiently treated. Because of lack of evidence, there is at present no reason to change the consensus reached there.

  10. Evidence for the safety of ascorbic acid administration to the premature infant. (United States)

    Bass, W T; Malati, N; Castle, M C; White, L E


    Ascorbic acid (AA), a plasma antioxidant, is maintained at high levels in premature fetal blood and declines rapidly postpartum. The sudden reduction in blood AA levels secondary to premature delivery may increase the risk of oxidant injury, that is, bronchopulmonary dysplasia and intraventricular hemorrhage. There is concern that administration of AA to premature infants, in an effort to increase antioxidant capacity, may cause hemolysis. We felt that the benefits of early AA administration and prevention of the immediate postnatal drop in blood AA levels, might outweigh the risks of erthrocyte damage. Fifty one high-risk premature infants were randomized to receive either normal saline or 100 mg/kg of AA, daily for the first week of life. Double-blind comparisons were made of hemoglobin, hematocrit, erythrocyte morphology, bilirubin, number of blood transfusions and days of phototherapy, renal function tests, the incidence of infection, bronchopulmonary dysplasia, and intraventricular hemorrhage during the first month of life. The administration of AA prevented the immediate postnatal drop in AA and was not associated with evidence of increased hemolysis. No significant differences in renal function, rate of infection, bronchopulmonary dysplasia, or intraventricular hemorrhage were seen between the two groups. This study suggests that AA administration to the premature infant is safe and supports the designing and performance of larger clinical studies of the antioxidant properties of AA.

    William CS CHO


    Full Text Available Complementary and alternative medicine has been increasingly utilized by cancer patients in developed countries. Among the various forms of complementary and alternative medicine, Traditional Chinese Medicine is one of the few that has a well constructed theoretical framework and established treatment approaches for diseases including cancer. Recent research has revealed growing evidence suggesting that Traditional Chinese Medicine is effective in the supportive care of cancer patients during and after major conventional cancer treatments. This paper succinctly summarizes some published clinical evidence and meta-analyses which support the usage of various Traditional Chinese Medicine treatment strategies including Chinese herbal medicine, acupuncture and Qigong in supportive cancer care.

    Full Text Available Being important for the proper functioning of the management activity conducted at the local public administration level, local autonomy cannot occur without the support coming from other rules of organization and functioning of local administrative system. From this perspective, in this paper we propose to analyze the content of decentralization, eligibility of authorities and consultation of citizens in solving local problems, in order to highlight how each of these principles demonstrates the efficiency of autonomy. Moving power from central public administration authorities to local authorities in the decentralization process, making authorities of administrative-territorial units eligible and the involvement of local community members in solving problems affecting them are clear evidence of the occurrence of autonomy in local public administration management.

  20. NICU nurse educators: what evidence supports your teaching strategies? (United States)

    Pilcher, Jobeth


    One of our roles as nurse educators is to teach best practices related to patient care. However, have you ever stopped to think about what evidence supports your teaching strategies? Just as our patients deserve care that is based on the best available evidence, our learners also deserve education that is based on evidence.1-3 With so many advances in knowledge, technology, and even life itself, it is interesting that education has changed very little over the past 100 years. A study among 946 nurse educators documented that most teach the way they were taught.4 In addition, even after learning new strategies, educators often continue teaching in the manner they are most comfortable. However, this trend is beginning to change. Nurse educators are becoming increasingly aware of and willing to try new and innovative teaching strategies. Educators are also seeking out evidence-based teaching strategies and are becoming more involved in nursing education research.

    With the support of the World Health Organization's Evidence-Informed Policy Network, knowledge translation platforms have been developed throughout Africa, the Americas, Eastern Europe, and Asia to further evidence-informed national health policy. In this commentary, we discuss the approaches, activities and early lessons learned from the development of a Knowledge Translation Platform in Malawi (KTPMalawi). Through ongoing leadership, as well as financial and administrative support, the Malawi Ministry of Health has strongly signalled its intention to utilize a knowledge translation platform methodology to support evidence-informed national health policy. A unique partnership between Dignitas International, a medical and research non-governmental organization, and the Malawi Ministry of Health, has established KTPMalawi to engage national-level policymakers, researchers and implementers in a coordinated approach to the generation and utilization of health-sector research. Utilizing a methodology developed and tested by knowledge translation platforms across Africa, a stakeholder mapping exercise and initial capacity building workshops were undertaken and a multidisciplinary Steering Committee was formed. This Steering Committee prioritized the development of two initial Communities of Practice to (1) improve data utilization in the pharmaceutical supply chain and (2) improve the screening and treatment of hypertension within HIV-infected populations. Each Community of Practice's mandate is to gather and synthesize the best available global and local evidence and produce evidence briefs for policy that have been used as the primary input into structured deliberative dialogues. While a lack of sustained initial funding slowed its early development, KTPMalawi has greatly benefited from extensive technical support and mentorship by an existing network of global knowledge translation platforms. With the continued support of the Malawi Ministry of Health and the

  2. Trichloroethylene: Mechanistic, Epidemiologic and Other Supporting Evidence of Carcinogenic Hazard (United States)

    Rusyn, Ivan; Chiu, Weihsueh A.; Lash, Lawrence H.; Kromhout, Hans; Hansen, Johnni; Guyton, Kathryn Z.


    The chlorinated solvent trichloroethylene (TCE) is a ubiquitous environmental pollutant. The carcinogenic hazard of TCE was the subject of a 2012 evaluation by a Working Group of the International Agency for Research on Cancer (IARC). Information on exposures, relevant data from epidemiologic studies, bioassays in experimental animals, and toxicity and mechanism of action studies was used to conclude that TCE is carcinogenic to humans (Group 1). This article summarizes the key evidence forming the scientific bases for the IARC classification. Exposure to TCE from environmental sources (including from hazardous waste sites and contaminated water) is common throughout the world. While workplace use of TCE has been declining, occupational exposures remain of concern, especially in developing countries. Strongest human evidence is from studies of occupational TCE exposure and kidney cancer. Positive, although less consistent, associations were reported for liver cancer and non-Hodgkin's lymphoma. TCE is carcinogenic at multiple sites in multiple species and strains of experimental animals. The mechanistic evidence includes extensive data on the toxicokinetics and genotoxicity of TCE and its metabolites. Together, available evidence provided a cohesive database supporting the human cancer hazard of TCE, particularly in the kidney. For other target sites of carcinogenicity, mechanistic and other data were found to be more limited. Important sources of susceptibility to TCE toxicity and carcinogenicity were also reviewed by the Working Group. In all, consideration of the multiple evidence streams presented herein informed the IARC conclusions regarding the carcinogenicity of TCE. PMID:23973663

  6. The new polio eradication end game: rationale and supporting evidence. (United States)

    Sutter, Roland W; Platt, Lauren; Mach, Ondrej; Jafari, Hamid; Aylward, R Bruce


    Polio eradication requires the removal of all polioviruses from human populations, whether wild poliovirus or those emanating from the oral poliovirus vaccine (OPV). The Polio Eradication & Endgame Strategic Plan 2013-2018 provides a framework for interruption of wild poliovirus transmission in remaining endemic foci and lays out a plan for the new polio end game, which includes the withdrawal of Sabin strains, starting with type 2, and the introduction of inactivated poliovirus vaccine, for risk mitigation purposes. This report summarizes the rationale and evidence that supports the policy decision to switch from trivalent OPV to bivalent OPV and to introduce 1 dose of inactivated poliovirus vaccine into routine immunization schedules, and it describes the proposed implementation of this policy in countries using trivalent OPV.

  7. Decision support to the public space administrator for managing urban building sites nuisances


    Hankach, Pierre; SADOUN, Isma; AMANZOUGARENE, Fatiha; CHACHOUA, Mohamed; Zeitouni, Karine; MARTIN, Jean Marc


    Effective planning of urban building sites is essential because they are often a source of various kinds of nuisances. In this paper, we present a decision support system for the public space administrator in order to manage building sites nuisances efficiently. The decision support offered through the system is a hybrid approach of two categories. In the first, the decision maker is assisted by supplying relevant information so he can choose the appropriate actions. The second involves activ...

  8. Developing research competence to support evidence-based practice. (United States)

    Burke, Lora E; Schlenk, Elizabeth A; Sereika, Susan M; Cohen, Susan M; Happ, Mary Beth; Dorman, Janice S


    This article describes one step in the process that was undertaken to prepare for the introduction of evidence-based practice (EBP) into the curriculum across the Bachelor of Science in Nursing, Master of Science in Nursing, and Doctor of Philosophy programs, as well as the programs that were under development, Clinical Nurse Leader and Doctor of Nursing Practice, at the University of Pittsburgh School of Nursing. Expected research competencies were identified for each level or academic year within each program. Based on these competencies, recommendations on how to modify the curriculum into one that would support students' acquisition and development of the skills necessary to be successful in matriculating through an EBP curriculum were developed. Evaluation mechanisms for the achievement of these competencies vary across the academic programs and will include performance on capstone projects, comprehensive examinations, and program milestones for doctoral students. The establishment of evidence-based competencies provided a foundation for the development of new teaching approaches and the curricular revisions across the three academic programs. Thus, the University of Pittsburgh model of educating for EBP is based on a sequential layering of research competencies throughout the curriculum.

  12. Improvements of Decision Support Systems for Public Administrations via a Mechanism of Co-creation of Value

    Directory of Open Access Journals (Sweden)

    Tindara Abbate


    Full Text Available This paper focuses on a possible improvement of knowledge-based decision support systems for human resource management within Public Administrations, using a co-creation of value’s mechanism, according to the Service-Dominant Logic (SDL paradigm. In particular, it applies ontology-driven data entry procedures to trigger the cooperation between the Public Administration itself and its employees. Advantages in such sense are evident: constraining the data entry process by means of the term definition ontology improves the quality of gathered data, thus reducing potential mismatching problems and allowing a suitable skill gap analysis among real and ideal workers competence profiles. The procedure foresees the following steps: analyzing organograms and job descriptions; modelling Knowledge, Skills and Attitudes (KSA for job descriptions; transforming KSAs of job descriptions into a standard-based model with integrations of other characteristics; extracting information from Curricula Vitae according to the selected model; comparing profiles and roles played by the employees.The 'a priori' ontology-driven approach adequately supports the operations that involve both the Public Administration and employees, as for the data storage of job descriptions and curricula vitae. The comparison step is useful to understand if employees perform roles that are coherent with their own professional profiles.The proposed approach has been experimented on a small test case and the results show that its objective evaluation represents an improvement for a decision support system for the re-organization of Italian Public Administrations where, unfortunately often, people are engaged in activities that are not so close to their competences.

  13. Hospital administration team development and support in a children's cancer service. (United States)

    Slater, Penelope J


    The administration team in the Queensland Children's Cancer Centre at the Royal Children's Hospital, Brisbane, included a team of 16 administration staff supporting the service and the state-wide clinical network. Shortly after the creation of a new expanded service, issues became apparent in administration team morale, relationships, communication, processes, leadership, support and training. The analysis of these issues included team interviews and surveys, consultation with senior administration staff and monthly sick leave monitoring. Strategies implemented included providing information; the joint development of a team business plan and individual performance plans; a review of the team's structure, workload and business processes; engaging staff in quality improvements; and the development of relationships and leadership. As a result, the team reported being more comfortable and supported in their roles, had improved morale and worked better together with more consistent and improving business processes. They had clear purpose and expectations of their roles, displayed better customer service and had reduced sick leave. The study shows that in a high stress environment, such as a children's cancer centre, attention to the team's culture, vision and purpose, providing information and improving communication and relationships, when combined with a team's enthusiasm, will improve the team's growth, cooperation and work outcomes.

  14. Teaching strategies to support evidence-based practice. (United States)

    Winters, Charlene A; Echeverri, Rebecca


    Evidence-based practice is an expected core competency of all health care clinicians regardless of discipline. Use of evidence-based practice means integrating the best research with clinical expertise and patient values to achieve optimal health outcomes. Evidence-based practice requires nurses to access and appraise evidence rapidly before integrating it into clinical practice. Role modeling and integrating the skills necessary to develop evidence-based practice into clinical and nonclinical courses is an important part in developing positive attitudes toward evidence-based practice, an essential first step to using evidence to guide practice decisions. The step-by-step approach to evidence-based practice proposed by Melnyk and colleagues provides an excellent organizing framework for teaching strategies specifically designed to facilitate nurses' knowledge and skill development in evidence-based practice.

  16. Professional Parity Between Co-Teachers in Secondary Science and Math As Influenced By Administrative Support (United States)

    Nordh, Camilla S.


    School improvement plans, budget constraints, and compliance mandates targeting academic progress for all students indicate a need for maximal professional efficacy at every level in the educational system, including parity between co-teachers in the co-teaching service delivery model. However, research shows that the special education co-teacher frequently assumes an assistive role while the general education co-teacher adopts a leading role in the classroom. When the participants in a co-teaching partnership fail to equitably share the professional responsibilities for which both teachers are qualified to perform, overall efficacy is compromised in that the special education teacher is not exercising his or her qualified expertise. Administrative support can be a primary influencing factor in increasing parity between the co-teachers. A qualitative study using a phenomenological design was conducted to explore the influences of co-teacher attitudes and administrative support on professional parity in co-taught secondary science and math classrooms. Content analysis was used to interpret data from interviews with five special education and 15 general education co-teachers at eight secondary schools in a suburban school district in a mid-Atlantic state. Five themes emerged from the data: content mastery by the special education co-teacher, joint planning time for co-teachers, continuity within co-teaching dyads, compatible personalities between co-teachers, and clear administrative expectations about co-teaching. Results indicate that administrative support to consider the content mastery of the special education co-teacher is the most influential factor to parity, followed by the co-teaching partners having joint planning time and that both can be implemented through scheduling and assignment considerations rather than training initiatives. The results provide an examination of each theme as it pertains to the issue of professional efficacy in co-teaching and

  18. American Dental Association's Resources to Support Evidence-Based Dentistry. (United States)

    Aravamudhan, K; Frantsve-Hawley, Julie


    Time and access have often been cited as barriers to implementing Evidence-Based Dentistry (EBD). This paper describes a new web-based resource launched by the American Dental Association to enable practitioners to incorporate evidence into treatment planning. The website offers a database of systematic reviews, critical summaries of systematic reviews, evidence-based clinical recommendations and links to external resources to enable practitioners to access evidence at the point of care. In addition the site offers an online space for clinicians to suggest clinical scenarios where evidence is lacking. This could potentially be a source of topics to drive future research. With the explosion in the use of information technology within a dental office, this web-site will serve as the one-stop resource for credible scientific information for practitioners.

  19. Evidence supporting the use of recombinant activated factor VII in congenital bleeding disorders

    Full Text Available Pär I Johansson, Sisse R OstrowskiCapital Region Blood Bank, Section for Transfusion Medicine, Rigshospitalet, University of Copenhagen, Copenhagen, DenmarkBackground: Recombinant activated factor VII (rFVIIa, NovoSeven® was introduced in 1996 for the treatment of hemophilic patients with antibodies against coagulation factor VIII or IX.Objective: To review the evidence supporting the use of rFVIIa for the treatment of patients with congenital bleeding disorders.Patients and methods: English-language databases were searched in September 2009 for reports of randomized controlled trials (RCTs evaluating the ability of rFVIIa to restore hemostasis in patients with congenital bleeding disorders.Results: Eight RCTs involving 256 hemophilic patients with antibodies against coagulation factors, also known as inhibitors, were identified. The evidence supporting the use of rFVIIa in these patients was weak with regard to dose, clinical setting, mode of administration, efficacy, and adverse events, given the limited sample size of each RCT and the heterogeneity of the studies.Conclusion: The authors suggest that rFVIIa therapy in hemophilic patients with inhibitors should be based on the individual’s ability to generate thrombin and form a clot, and not on the patient’s weight alone. Therefore, assays for thrombin generation, such as whole-blood thromboelastography, have the potential to significantly improve the treatment of these patients.Keywords: hemophilia, inhibitors, coagulation factor VIII, coagulation factor IX, rFVIIa, NovoSeven, FEIBA, hemostasis, RCT

  1. Vaccines and autism: evidence does not support a causal association. (United States)

    DeStefano, F


    A suggested association between certain childhood vaccines and autism has been one of the most contentious vaccine safety controversies in recent years. Despite compelling scientific evidence against a causal association, many parents and parent advocacy groups continue to suspect that vaccines, particularly measles-mumps-rubella (MMR) vaccine and thimerosal-containing vaccines (TCVs), can cause autism.

  2. Dental School Administrators' Attitudes Towards Providing Support Services for LGBT-Identified Students. (United States)

    Behar-Horenstein, Linda S; Morris, Dustin R


    A lack of curriculum time devoted to teaching dental students about the needs of lesbian, gay, bisexual, and transgendered (LGBT) health care patient needs and biases against LGBT students and faculty have been reported. Understanding dental school administrators' attitudes about LGBT students' needs might provide further insight into these long-standing issues. The aims of this study were to develop a survey to assess dental administrators' attitudes regarding the support services they believe LGBT-identified students need, to identify dental schools' current diversity inclusion policies, and to determine what types of support dental schools currently provide to LGBT students. A survey developed with the aid of a focus group, cognitive interviewing, and pilot testing was sent to 136 assistant and associate deans and deans of the 65 U.S. and Canadian dental schools. A total of 54 responses from 43 (66%) schools were received from 13 deans, 29 associate deans, and 11 assistant deans (one participant did not report a position), for a 40% response rate. The findings suggest there is a considerable lack of knowledge or acknowledgment of LGBT dental students' needs. Future studies are needed to show the importance of creating awareness about meeting the needs of all dental student groups, perhaps through awareness campaigns initiated by LGBT students.

  4. [Administration of intravenous immunoglobulins in neurology. An evidence-based consensus: update 2010]. (United States)

    Stangel, M; Gold, R


    Our knowledge on the clinical efficacy of intravenous immunoglobulins (IVIg) in neurological diseases has greatly increased in the last 5 years. Liquid formulations with a higher concentration of IVIg have simplified administration. Despite a worldwide increase in plasma production it is still a valuable biological product which is why current indications must be continuously validated. Long-term efficacy of the preparation Gamunex could be demonstrated in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). In acute myasthenic worsening a dose of 1 g IVIg/kg body weight appears to be sufficient for clinical stabilization. New indications, such as the postpolio syndrome or Alzheimer's disease are being explored in clinical trials. In addition to the consensus statement from 2004 the evidence for clinical use of IVIg has been re-evaluated and recommendations are given.

  5. Standardized Nursing Documentation Supports Evidence-Based Nursing Management. (United States)

    Mykkänen, Minna; Miettinen, Merja; Saranto, Kaija


    Nursing documentation is crucial to high quality, effective and safe nursing care. According to earlier studies nursing documentation practices vary and nursing classifications used in electronic patient records (EPR) are not yet standardized internationally nor nationally. A unified national model for documenting patient care improves information flow in nursing practice, management, research and development toward evidence-based nursing care. Nursing documentation quality, accuracy and development requires follow-up and evaluation. An audit instrument is used in the Kuopio University Hospital (KUH) when evaluating nursing documentation. The results of the auditing process suggest that the national nursing documentation model fulfills nurses' expectations of electronic tools, facilitating their important documentation duty. This paper discusses the importance of using information about nursing documentation and how we can take advantage of structural information in evidence-based nursing management.

    Ahmad Ghanizadeh


    Full Text Available Background: This study evaluates the evidence-based administration of risperidone and paliperidone for the treating children and adolescents with conduct disorder (CD. Materials and Methods: A review of the current literature from clinical trials that investigated the efficacy of risperidone and paliperidone on CD considering the inclusion criteria and search strategies was performed by a search of PubMed and Google Scholar databases. Results: Out of 53 titles, 31 were irrelevant. The abstract of 22 potentially related articles were studied. Only six articles reported the results of clinical trial. However, one of them reported the effect of risperidone on conduct behaviors in autistic disorders. One study was a re-analysis of two previous studies, one study reported the effects of maintenance versus withdrawal of risperidone treatment and two studies included children with sub-average intelligence. Headache, somnolence and increased appetite are among the most common reported adverse effects. No study examined the effect of paliperidone on CD was found. Conclusion: Current literature suggests that risperidone could be effective for treating some conduct behaviors in children and adolescents. The effect of risperidone on CD is not a well-researched area. There is no well-controlled evidence based reports about the safety and efficacy of risperidone for the treatment of CD. Further trials should examine the efficacy of these medications on CD rather than conduct behaviors or disruptive behavior disorders.

  9. Changing behavior: evidence based practice supporting hair removal with clippers. (United States)

    Waddington, Carolyn


    Evidence based practice demonstrates using clippers immediately before surgery, when perioperative hair removal is necessary, results in the fewest surgical site infections (Kjonniksen, Andersen, Sondenaa, & Segadal, 2002). In addition, one of The Joint Commission's national patient safety goals for 2008 is "to reduce the risk of healthcare associated infections" (The Joint Commission, 2008, Goal 7). Therefore, a project was undertaken to change perioperative nursing care in a large teaching hospital from using razors for hair removal in the perioperative setting to using clippers. Change is difficult and encompasses many interdisciplinary areas. A description of the process of utilizing evidence to change behavior in the perioperative setting and its outcomes will be provided in this paper. Klevens, et al., (2007) reported that 22% of healthcare associated infections were the result of surgical site infections (SSIs). Changing practice to utilizing clippers for hair removal is an extrinsic factor of SSIs that can be easily modified. Otorhinolaryngology (ORL) patients that require hair removal before surgery (i.e., acoustic neuroma, cranial-facial resections, and head and neck reconstruction) may benefit from this change in practice. Perioperative nurses are in a prime position to reduce the incidence of SSIs in ORL patients.

  10. Perioperative glucocorticosteroid supplementation is not supported by evidence. (United States)

    de Lange, Dylan W; Kars, Marleen


    Ever since the first descriptions of adrenal insufficiency following exogenous supplementation physicians dread to abolish perioperative glucocorticosteroid supplementation. Now, 55 years after the first publications we can challenge those first reports. However, these cases have resulted in the supplementation of supraphysiological doses of glucocorticosteroids to patients that use exogenous corticosteroids: the so-called perioperative glucocorticosteroid supplementation or "(gluco)corticosteroid stress scheme". It is very questionable whether a dose that exceeds the normal daily production of 5.7 mg cortisol per square meter of body surface area is necessary to prevent perioperative hypotension. Retrospective, prospective and randomised studies, though all methodologically flawed, are discussed and show that continuation of the "basal" amount of glucocorticosteroids is sufficient to counterbalance surgical stress. The current and rather defensive strategy of perioperative supraphysiological glucocorticosteroid supplementation is not embedded in medical evidence. Additionally, high doses of glucocorticosteroids have disadvantages that should not be ignored.

  11. Evidence supporting product standards for carcinogens in smokeless tobacco products. (United States)

    Hatsukami, Dorothy K; Stepanov, Irina; Severson, Herb; Jensen, Joni A; Lindgren, Bruce R; Horn, Kimberly; Khariwala, Samir S; Martin, Julia; Carmella, Steven G; Murphy, Sharon E; Hecht, Stephen S


    Smokeless tobacco products sold in the United States vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of smokeless tobacco use versus constituent levels in the smokeless tobacco product in exposure of users to carcinogens. In this study, smokeless tobacco users of brands varying in nicotine and TSNA content were recruited from three different regions in the U.S. Participants underwent two assessment sessions. During these sessions, demographic and smokeless tobacco use history information along with urine samples to assess biomarkers of exposure and effect were collected. During the time between data collection, smokeless tobacco users recorded the amount and duration of smokeless tobacco use on a daily basis using their diary cards. Results showed that independent of pattern of smokeless tobacco use and nicotine yields, levels of TSNA in smokeless tobacco products played a significant role in carcinogen exposure levels. Product standards for reducing levels of TSNA in smokeless tobacco products are necessary to decrease exposure to these toxicants and potentially to reduce risk for cancer.

  12. Periodontal self-care: evidence-based support. (United States)

    Drisko, Connie L


    The focus of this review on periodontal self-care will be based primarily on the results of systematic reviews and meta-analyses. Based on the evidence gleaned from systematic reviews, it is notable that most authors of these reviews commented on the relatively small number of trials that could pass the quality-assessment inclusion in the systematic review. Interproximal devices, namely interproximal brushes, are more effective for reducing interproximal plaque and gingivitis than are flossing or brushing alone. Some added benefit may be attributed to the use of rotational oscillation powered toothbrushes over manual toothbrushes. Recommendations by the dentist and dental hygienist to add one or more chemotherapeutic agents to the typical oral hygiene regimen has been shown, in systematic reviews and meta-analyses, to reduce the level of plaque and gingival inflammation in patients. Oral irrigation does not seem to reduce visible plaque but does tend to reduce inflammation, determined by the presence of bleeding on probing, the gingival index score and probing depth measurements. To date, high-quality evidence is either lacking or weak in some areas regarding the efficacy of self-care and periodontal disease. Low educational attainment, smoking and socio-economic status are related to adverse periodontal health outcomes. Variation in self-esteem, self-confidence and perfectionism are associated with oral health status and oral health behaviors. Better understanding of the psychological factors associated with oral hygiene would be of benefit in further developing strategies to help patients improve their oral hygiene in addition to helping professionals design better programs on prevention and education.

  13. Evidence for Evolution as Support for Big Bang (United States)



    With the exception of ZERO, the concept of BIG BANG is by far the most bizarre creation of the human mind. Three classical pillars of the Big Bang model of the origin of the universe are generally thought to be: (i) The abundances of the light elements; (ii) the microwave back-ground radiation; and (iii) the change with cosmic epoch in the average properties of galaxies (both active and non-active types). Evidence is also mounting for redshift dependence of the intergalactic medium, as discussed elsewhere in this volume in detail. In this contribution, I endeavour to highlight a selection of recent advances pertaining to the third category. The widely different levels of confidence in the claimed observational constraints in the field of cosmology can be guaged from the following excerpts from two leading astrophysicists: "I would bet odds of 10 to 1 on the validity of the general 'hot Big Bang' concept as a description of how our universe has evolved since it was around 1 sec. old" -M. Rees (1995), in 'Perspectives in Astrophysical Cosmology' CUP. "With the much more sensitive observations available today, no astrophysical property shows evidence of evolution, such as was claimed in the 1950s to disprove the Steady State theory" -F. Hoyle (1987), in 'Fifty years in cosmology', B. M. Birla Memorial Lecture, Hyderabad, India. The burgeoning multi-wavelength culture in astronomy has provided a tremendous boost to observational cosmology in recent years. We now proceed to illustrate this with a sequence of examples which reinforce the picture of an evolving universe. Also provided are some relevant details of the data used in these studies so that their scope can be independently judged by the readers.

  14. Evidence supporting vertical transmission of Salmonella in dairy cattle. (United States)

    Hanson, D L; Loneragan, G H; Brown, T R; Nisbet, D J; Hume, M E; Edrington, T S


    We set out to investigate whether Salmonella enterica could be recovered from various tissues of viable neonatal calves immediately following parturition. Eleven samples were aseptically collected from each of 20 calves and consisted of both left and right subiliac and prescapular lymph nodes (LN), mesenteric LN, spleen and liver, as well as intestinal tissue (including luminal contents) from the small intestine, caecum, spiral colon and rectum. In addition, a faecal sample was collected from 19 of the dams. Salmonella was recovered from at least one sample from 10 of the 20 neonates. Across all calves, Salmonella was recovered from 12·7% of all samples and from LN in particular, Salmonella was recovered from 10·0%, 5·0%, and 5·0% of subiliac, prescapular, and mesenteric LN, respectively. Within calves, Salmonella was recovered from 0% to 73% of samples and across tissues, estimates of Salmonella prevalence were greatest in the caecum (30%) but was never recovered from the right pre-scapular LN. These data provide evidence of vertical transmission from a dam to her fetus such that viable calves are born already infected and thereby not requiring faecal-oral exposure for transmission. This new knowledge ought to challenge - or at least add to - existing paradigms of Salmonella transmission dynamics within cattle herds.

  15. Broad support evident for the emerging specialty of orofacial pain. (United States)

    Talley, R L; Fricton, J R; Okeson, J P


    The emerging field of Orofacial Pain is being considered by the American Dental Association for full status as a new dental specialty. Many recent advances in the neuroscience of orofacial pain have lead to treatments by orofacial pain dentists that provide significant relief for patients with chronic orofacial pain disorders. However, access to this care has been limited leaving many patients to continue to suffer. Subsequently, recent efforts to improve this by developing the field into a specialty have shown broad support among dentists and increased awareness of the benefits this field can provide for dentists and their patients. A recent survey of 805 individuals in the general population who reported having a persistent pain disorder revealed that more than four out of 10 people have yet to find adequate relief, saying their pain is out of control-despite having the pain for more than 5 years and switching doctors at least once. "This survey suggests that there are millions of people living with severe uncontrolled pain," says Russell Portenoy, MD, President of the American Pain Society. "This is a great tragedy. Although not everyone can be helped, it is very likely that most of these patients could benefit if provided with state-of-the-art therapies and improved access to pain specialists when needed." (1). Development of the field of Orofacial Pain into a dental specialty has been motivated primarily by this issue; patients with complex chronic orofacial pain disorders have not been historically treated well by any discipline of health care. Recent studies of chronic orofacial pain patients have found that these patients have a high number of previous clinicians and have endured many years with pain prior to seeing an orofacial pain dentist (2) (Fig. 1). Complex pain patients and the clinicians who see them are often confused about whom they should consult for relief of the painful disorder. Treatment for these patients within the existing structure of

  16. The Ganong paradigm: Converging evidence supporting initial phoneme weighting (United States)

    Tracy, Erik C.; Pitt, Mark A.


    In the present experiment we investigate whether the initial phoneme is given more weight in word recognition [W. D. Marslen-Wilson and A. Welsh, Cognit. Psych. 10, 29-63 (1978)] or if all phonemes in a word are weighted equally [C. M. Connine, D. G. Blasko, and D. Titone, J. Mem. Lang. 32, 193-210 (1993)]. Using the Ganong paradigm [W. F. Ganong, JEP:HPP. 6, 110-125 (1980)], participants were instructed to categorize a final ambiguous fricative in the target items, which included both words and pseudowords. Pseudowords were created by changing either the initial or a medial phoneme within the words. For example, the word diminish was altered to create the pseudowords timinish and dimimish. In addition, initial and medial phonemes were altered by either one or three distinctive features. The differences in the labeling of the final ambiguous fricative in the target items led to the conclusion that the initial phoneme is weighted more heavily. [Work supported by NIDCD.

  17. Population-based public health interventions: practice-based and evidence-supported. Part I. (United States)

    Keller, Linda Olson; Strohschein, Susan; Lia-Hoagberg, Betty; Schaffer, Marjorie A


    The Intervention Wheel is a population-based practice model that encompasses three levels of practice (community, systems, and individual/family) and 17 public health interventions. Each intervention and practice level contributes to improving population health. The Intervention Wheel, previously known as the Public Health Intervention Model, was originally introduced in 1998 by the Minnesota Department of Health, Section of Public Health Nursing. The model has been widely disseminated and used throughout the United States since that time. The evidence supporting the Intervention Wheel was recently subjected to a rigorous critique by regional and national experts. This critical process, which involved hundreds of public health nurses, resulted in a more robust Intervention Wheel and established the validity of the model. The critique also produced basic steps and best practices for each of the 17 interventions. Part I describes the Intervention Wheel, defines population-based practice, and details the recommended modifications and validation process. Part II provides examples of the innovative ways that the Intervention Wheel is being used in public health/public health nursing practice, education, and administration. The two articles provide a foundation and vision for population-based public health nursing practice and direction for improving population health.

    In active implementation science frameworks, coaching has been described as an important competency "driver" to ensure evidence-based practices are implemented as intended. Empirical evidence also has identified coaching as a promising job-embedded professional development strategy to support implementation of quality teaching practices.…

  19. Evidence-informed health policy 2 – Survey of organizations that support the use of research evidence

    Directory of Open Access Journals (Sweden)

    Oxman Andrew D


    Full Text Available Abstract Background Previous surveys of organizations that support the development of evidence-informed health policies have focused on organizations that produce clinical practice guidelines (CPGs or undertake health technology assessments (HTAs. Only rarely have surveys focused at least in part on units that directly support the use of research evidence in developing health policy on an international, national, and state or provincial level (i.e., government support units, or GSUs that are in some way successful or innovative or that support the use of research evidence in low- and middle-income countries (LMICs. Methods We drew on many people and organizations around the world, including our project reference group, to generate a list of organizations to survey. We modified a questionnaire that had been developed originally by the Appraisal of Guidelines, Research and Evaluation in Europe (AGREE collaboration and adapted one version of the questionnaire for organizations producing CPGs and HTAs, and another for GSUs. We sent the questionnaire by email to 176 organizations and followed up periodically with non-responders by email and telephone. Results We received completed questionnaires from 152 (86% organizations. More than one-half of the organizations (and particularly HTA agencies reported that examples from other countries were helpful in establishing their organization. A higher proportion of GSUs than CPG- or HTA-producing organizations involved target users in the selection of topics or the services undertaken. Most organizations have few (five or fewer full-time equivalent (FTE staff. More than four-fifths of organizations reported providing panels with or using systematic reviews. GSUs tended to use a wide variety of explicit valuation processes for the research evidence, but none with the frequency that organizations producing CPGs, HTAs, or both prioritized evidence by its quality. Between one-half and two-thirds of organizations

  2. SUPPORT Tools for evidence-informed health Policymaking (STP) 14: Organising and using policy dialogues to support evidence-informed policymaking. (United States)

    Lavis, John N; Boyko, Jennifer A; Oxman, Andrew D; Lewin, Simon; Fretheim, Atle


    This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. Policy dialogues allow research evidence to be considered together with the views, experiences and tacit knowledge of those who will be involved in, or affected by, future decisions about a high-priority issue. Increasing interest in the use of policy dialogues has been fuelled by a number of factors: 1. The recognition of the need for locally contextualised 'decision support' for policymakers and other stakeholders 2. The recognition that research evidence is only one input into the decision-making processes of policymakers and other stakeholders 3. The recognition that many stakeholders can add significant value to these processes, and 4. The recognition that many stakeholders can take action to address high-priority issues, and not just policymakers. In this article, we suggest questions to guide those organising and using policy dialogues to support evidence-informed policymaking. These are: 1. Does the dialogue address a high-priority issue? 2. Does the dialogue provide opportunities to discuss the problem, options to address the problem, and key implementation considerations? 3. Is the dialogue informed by a pre-circulated policy brief and by a discussion about the full range of factors that can influence the policymaking process? 4. Does the dialogue ensure fair representation among those who will be involved in, or affected by, future decisions related to the issue? 5. Does the dialogue engage a facilitator, follow a rule about not attributing comments to individuals, and not aim for consensus? 6. Are outputs produced and follow-up activities undertaken to support action?

  3. Safeguarding the process of drug administration with an emphasis on electronic support tools (United States)

    Seidling, Hanna M; Lampert, Anette; Lohmann, Kristina; Schiele, Julia T; Send, Alexander J F; Witticke, Diana; Haefeli, Walter E


    Aims The aim of this work is to understand the process of drug administration and identify points in the workflow that resulted in interventions by clinical information systems in order to improve patient safety. Methods To identify a generic way to structure the drug administration process we performed peer-group discussions and supplemented these discussions with a literature search for studies reporting errors in drug administration and strategies for their prevention. Results We concluded that the drug administration process might consist of up to 11 sub-steps, which can be grouped into the four sub-processes of preparation, personalization, application and follow-up. Errors in drug handling and administration are diverse and frequent and in many cases not caused by the patient him/herself, but by family members or nurses. Accordingly, different prevention strategies have been set in place with relatively few approaches involving e-health technology. Conclusions A generic structuring of the administration process and particular error-prone sub-steps may facilitate the allocation of prevention strategies and help to identify research gaps.

  4. Empirically supported treatments in psychotherapy: towards an evidence-based or evidence-biased psychology in clinical settings?

    Directory of Open Access Journals (Sweden)

    Gianluca Castelnuovo


    Full Text Available The field of research and practice in psychotherapy has been deeply influenced by two different approaches: the empirically supported treatments (ESTs movement, linked with the evidence-based medicine (EBM perspective and the “Common Factors” approach, typically connected with the “Dodo Bird Verdict”. About the first perspective, since 1998 a list of ESTs has been established in mental health field. Criterions for “well-established” and “probably efficacious” treatments have arisen. The development of these kinds of paradigms was motivated by the emergence of a “managerial” approach and related systems for remuneration also for mental health providers and for insurance companies. In this article ESTs will be presented underlining also some possible criticisms. Finally complementary approaches, that could add different evidence in the psychotherapy research in comparison with traditional EBM approach, are presented.

  5. Acute phenobarbital administration induces hyperalgesia: pharmacological evidence for the involvement of supraspinal GABA-A receptors

    Directory of Open Access Journals (Sweden)

    C.M. Yokoro


    Full Text Available The aim of the present study was to determine if phenobarbital affects the nociception threshold. Systemic (1-20 mg/kg phenobarbital administration dose dependently induced hyperalgesia in the tail-flick, hot-plate and formalin tests in rats and in the abdominal constriction test in mice. Formalin and abdominal constriction tests were the most sensitive procedures for the detection of hyperalgesia in response to phenobarbital compared with the tail-flick and hot-plate tests. The hyperalgesia induced by systemic phenobarbital was blocked by previous administration of 1 mg/kg ip picrotoxin or either 1-2 mg/kg sc or 10 ng icv bicuculline. Intracerebroventricular phenobarbital administration (5 µg induced hyperalgesia in the tail-flick test. In contrast, intrathecal phenobarbital administration (5 µg induced antinociception and blocked systemic-induced hyperalgesia in this test. We suggest that phenobarbital may mediate hyperalgesia through GABA-A receptors at supraspinal levels and antinociception through the same kind of receptors at spinal levels.

  15. Automatic indexing and retrieval of encounter-specific evidence for point-of-care support. (United States)

    O'Sullivan, Dympna M; Wilk, Szymon A; Michalowski, Wojtek J; Farion, Ken J


    Evidence-based medicine relies on repositories of empirical research evidence that can be used to support clinical decision making for improved patient care. However, retrieving evidence from such repositories at local sites presents many challenges. This paper describes a methodological framework for automatically indexing and retrieving empirical research evidence in the form of the systematic reviews and associated studies from The Cochrane Library, where retrieved documents are specific to a patient-physician encounter and thus can be used to support evidence-based decision making at the point of care. Such an encounter is defined by three pertinent groups of concepts - diagnosis, treatment, and patient, and the framework relies on these three groups to steer indexing and retrieval of reviews and associated studies. An evaluation of the indexing and retrieval components of the proposed framework was performed using documents relevant for the pediatric asthma domain. Precision and recall values for automatic indexing of systematic reviews and associated studies were 0.93 and 0.87, and 0.81 and 0.56, respectively. Moreover, precision and recall for the retrieval of relevant systematic reviews and associated studies were 0.89 and 0.81, and 0.92 and 0.89, respectively. With minor modifications, the proposed methodological framework can be customized for other evidence repositories.

  16. Economic Impact of Support Service Program on Micro and Small Enterprises: The Case of Dire Dawa Administration, Ethiopia

    Directory of Open Access Journals (Sweden)

    B. Kassa


    Full Text Available Special attention has been given to untie the constraints of Micro and Small Enterprises in Ethiopia for they are important vehicles to address the challenges of unemployment, economic growth and equity in the country. The government is implementing different support service programs, in the forms of financial and business development, in different parts of the country. This study is aimed at evaluating economic impact of MSEs support service programs on enterprise sales, employment and capital asset formation in Dire Dawa Administration, Ethiopia. Propensity Score Matching is employed to estimate the impact of support service program. The result revealed that the program resulted in average increment of monthly sales by 28%, employee level by 42%, and capital asset formation by 60%. It is, therefore, indispensable to strengthen and expand the support service program to non participant enterprises by giving special attention to the major problems that participant enterprises are currently facing.

  17. Evidence-informed health policy 4 – Case descriptions of organizations that support the use of research evidence

    Directory of Open Access Journals (Sweden)

    Oxman Andrew D


    Full Text Available Abstract Background Previous efforts to produce case descriptions have typically not focused on the organizations that produce research evidence and support its use. External evaluations of such organizations have typically not been analyzed as a group to identify the lessons that have emerged across multiple evaluations. Case descriptions offer the potential for capturing the views and experiences of many individuals who are familiar with an organization, including staff, advocates, and critics. Methods We purposively sampled a subgroup of organizations from among those that participated in the second (interview phase of the study and (once from among other organizations with which we were familiar. We developed and pilot-tested a case description data collection protocol, and conducted site visits that included both interviews and documentary analyses. Themes were identified from among responses to semi-structured questions using a constant comparative method of analysis. We produced both a brief (one to two pages written description and a video documentary for each case. Results We conducted 51 interviews as part of the eight site visits. Two organizational strengths were repeatedly cited by individuals participating in the site visits: use of an evidence-based approach (which was identified as being very time-consuming and existence of a strong relationship between researchers and policymakers (which can be challenged by conflicts of interest. Two organizational weaknesses – a lack of resources and the presence of conflicts of interest – were repeatedly cited by individuals participating in the site visits. Participants offered two main suggestions for the World Health Organization (and other international organizations and networks: 1 mobilize one or more of government support, financial resources, and the participation of both policymakers and researchers; and 2 create knowledge-related global public goods. Conclusion The findings from

  19. Fresh Frozen Plasma Administration in the Neonatal Intensive Care Unit: Evidence-Based Guidelines. (United States)

    Motta, Mario; Del Vecchio, Antonio; Chirico, Gaetano


    Neonates receiving fresh frozen plasma (FFP) should do so according to evidence-based guidelines so as to reduce inappropriate use of this life-saving and costly blood product and to minimize associated adverse effects. The consensus-based uses of FFP in neonatology involve neonates with active bleeding and associated coagulopathy. However, because of limited and poor-quality evidence, considerable FFP utilization occurs outside these recommendations. In this review, we describe what we conclude are currently the best practices for the use of FFP in neonates, including interpreting neonatal coagulation tests and strategies for reducing unnecessary FFP transfusions.

  20. The characterization of neuroenergetic effects of chronic L-tyrosine administration in young rats: evidence for striatal susceptibility. (United States)

    Ferreira, Gabriela K; Carvalho-Silva, Milena; Gomes, Lara M; Scaini, Giselli; Teixeira, Leticia J; Mota, Isabella T; Schuck, Patrícia F; Ferreira, Gustavo C; Streck, Emilio L


    Tyrosinemia type II is an inborn error of metabolism caused by a deficiency in hepatic cytosolic aminotransferase. Affected patients usually present a variable degree of mental retardation, which may be related to the level of plasma tyrosine. In the present study we evaluated effect of chronic administration of L-tyrosine on the activities of citrate synthase, malate dehydrogenase, succinate dehydrogenase and complexes I, II, II-III and IV in cerebral cortex, hippocampus and striatum of rats in development. Chronic administration consisted of L-tyrosine (500 mg/kg) or saline injections 12 h apart for 24 days in Wistar rats (7 days old); rats were killed 12 h after last injection. Our results demonstrated that L-tyrosine inhibited the activity of citrate synthase in the hippocampus and striatum, malate dehydrogenase activity was increased in striatum and succinate dehydrogenase, complexes I and II-III activities were inhibited in striatum. However, complex IV activity was increased in hippocampus and inhibited in striatum. By these findings, we suggest that repeated administrations of L-tyrosine cause alterations in energy metabolism, which may be similar to the acute administration in brain of infant rats. Taking together the present findings and evidence from the literature, we hypothesize that energy metabolism impairment could be considered an important pathophysiological mechanism underlying the brain damage observed in patients with tyrosinemia type II.

  1. Community interventions providing care and support to orphans and vulnerable children: a review of evaluation evidence. (United States)

    Schenk, Katie D


    Children affected by HIV in their families and communities face multiple risks to their health, education and psychosocial wellbeing. Community interventions for children who have been orphaned or rendered vulnerable take many forms, including educational assistance, home-based care, legal protection and psychosocial support. Despite a recent influx of funding for programme implementation, there exists little evidence to inform policymakers about whether their investments are improving the lives of vulnerable children and meeting key benchmarks including the Millennium Development Goals. This paper reviews the current evidence base on evaluations of community interventions for orphans and vulnerable children (OVC) in high HIV-prevalence African settings, focusing on studies' methodologies. Sources reviewed include published research studies and evidence from the unpublished programmatic "grey literature" located through database and internet searches. A total of 21 studies, varying in scope and generalisability, were identified. Interventions reviewed address children's wellbeing through various strategies within their communities. Evaluation methodologies reflect quantitative and qualitative approaches, including surveys (with and without baseline or comparison data), costing studies, focus groups, interviews, case studies, and participatory review techniques. Varied study methodologies reflect diverse research questions, various intervention types, and the challenges associated with evaluating complex interventions; highlighting the need to broaden the research paradigm in order to build the evidence base by including quasi-experimental and process evaluation approaches, and seeking further insights through participatory qualitative methodologies and costing studies. Although findings overall indicate the value of community interventions in effecting measurable improvements in child and family wellbeing, the quality and rigour of evidence is varied. A strategic

    Directory of Open Access Journals (Sweden)

    Moynihan Ray


    Full Text Available Abstract Background Only a small number of previous efforts to describe the experiences of organizations that produce clinical practice guidelines (CPGs, undertake health technology assessments (HTAs, or directly support the use of research evidence in developing health policy (i.e., government support units, or GSUs have relied on interviews and then only with HTA agencies. Interviews offer the potential for capturing experiences in great depth, particularly the experiences of organizations that may be under-represented in surveys. Methods We purposively sampled organizations from among those who completed a questionnaire in the first phase of our three-phase study, developed and piloted a semi-structured interview guide, and conducted the interviews by telephone, audio-taped them, and took notes simultaneously. Binary or categorical responses to more structured questions were counted when possible. Themes were identified from among responses to semi-structured questions using a constant comparative method of analysis. Illustrative quotations were identified to supplement the narrative description of the themes. Results We interviewed the director (or his or her nominee in 25 organizations, of which 12 were GSUs. Using rigorous methods that are systematic and transparent (sometimes shortened to 'being evidence-based' was the most commonly cited strength among all organizations. GSUs more consistently described their close links with policymakers as a strength, whereas organizations producing CPGs, HTAs, or both had conflicting viewpoints about such close links. With few exceptions, all types of organizations tended to focus largely on weaknesses in implementation, rather than strengths. The advice offered to those trying to establish similar organizations include: 1 collaborate with other organizations; 2 establish strong links with policymakers and stakeholders; 3 be independent and manage conflicts of interest; 4 build capacity; 5 use good

  3. Multiple Lines Of Evidence Supporting Natural Attenuation: Lines Of Inquiry Supporting Monitored Natural Attenuation And Enhanced Attenuatin Of Chlorinated Solvents

    Energy Technology Data Exchange (ETDEWEB)

    Vangelas, Karen; Widemeirer, T. H.; Barden, M.J.; Dickson, W. Z.; Major, David


    The Department of Energy (DOE) is sponsoring an initiative to facilitate efficient, effective and responsible use of Monitored Natural Attenuation (MNA) and Enhanced Attenuation (EA) for chlorinated solvents. This Office of Environmental Management (EM) ''Alternative Project,'' focuses on providing scientific and policy support for MNA/EA. A broadly representative working group of scientists supports the project along with partnerships with regulatory organizations such as the Interstate Technology Regulatory Council (ITRC) and the United States Environmental Protection Agency (USEPA). The initial product of the technical working group was a summary report that articulated the conceptual approach and central scientific tenants of the project, and that identified a prioritized listing of technical targets for field research. This report documented the process in which: (1) scientific ground rules were developed, (2) lines of inquiry were identified and then critically evaluated, (3) promising applied research topics were highlighted in the various lines of inquiry, and (4) these were discussed and prioritized. The summary report will serve as a resource to guide management and decision making throughout the period of the subject MNA/EA Alternative Project. To support and more fully document the information presented in the summary report, the DOE is publishing a series of supplemental documents that present the full texts from the technical analyses within the various lines of inquiry (see listing). The following report--documenting our evaluation of the state of the science for the lines of evidence for supporting decision-making for MNA--is one of those supplemental documents.

    Directory of Open Access Journals (Sweden)

    José Valeriano FRÍAS-ACEITUNO


    Full Text Available This paper analyzes the factors underlying the development of e-government, as an overall process, as well as of each of the three stages identified in the prior literature (e-government, egovernance and e-democracy. The analysis has focused on 102 Spanish municipalities, and it consists in a content analysis of their web pages, based on an information index, in order to develop a dependency model. The results obtained indicate that Spanish municipalities show high information transparency regarding economic, environmental and social matters, allowing the undertaking of administrative proceedings online and actively promoting the participation of interest groups in strategic, sustainable and managerial issues. Our findings stress the importance of the municipality’s size and the ruling party’s political ideology of a deeper commitment with the development of e-government.

  8. The information infrastructure that supports evidence-based veterinary medicine: a comparison with human medicine. (United States)

    Toews, Lorraine


    In human medicine, the information infrastructure that supports the knowledge translation processes of exchange, synthesis, dissemination, and application of the best clinical intervention research has developed significantly in the past 15 years, facilitating the uptake of research evidence by clinicians as well as the practice of evidence-based medicine. Seven of the key elements of this improved information infrastructure are clinical trial registries, research reporting standards, systematic reviews, organizations that support the production of systematic reviews, the indexing of clinical intervention research in MEDLINE, clinical search filters for MEDLINE, and point-of-care decision support information resources. The objective of this paper is to describe why these elements are important for evidence-based medicine, the key developments and issues related to these seven information infrastructure elements in human medicine, how these 7 elements compare with the corresponding infrastructure elements in veterinary medicine, and how all of these factors affect the translation of clinical intervention research into clinical practice. A focused search of the Ovid MEDLINE database was conducted for English language journal literature published between 2000 and 2010. Two bibliographies were consulted and selected national and international Web sites were searched using Google. The literature reviewed indicates that the information infrastructure supporting evidence-based veterinary medicine practice in all of the 7 elements reviewed is significantly underdeveloped in relation to the corresponding information infrastructure in human medicine. This lack of development creates barriers to the timely translation of veterinary medicine research into clinical practice and also to the conduct of both primary clinical intervention research and synthesis research.

  9. Non-genetic data supporting genetic evidence for the eastern wolf (United States)

    Mech, L. David


    Two schools of thought dominate the molecular-genetics literature on Canis spp. (wolves) in the western Great Lakes region of the US and Canada: (1) they are hybrids between Canis lupus (Gray Wolf) and Canis latrans (Coyote), or (2) they are hybrids between the Gray Wolf and Canis lycaon (Eastern Wolf). This article presents 3 types of non-genetic evidence that bears on the controversy and concludes that all 3 support the second interpretation.

  10. Additional Interventions to Enhance the Effectiveness of Individual Placement and Support: A Rapid Evidence Assessment

    Directory of Open Access Journals (Sweden)

    Naomi Boycott


    Full Text Available Topic. Additional interventions used to enhance the effectiveness of individual placement and support (IPS. Aim. To establish whether additional interventions improve the vocational outcomes of IPS alone for people with severe mental illness. Method. A rapid evidence assessment of the literature was conducted for studies where behavioural or psychological interventions have been used to supplement standard IPS. Published and unpublished empirical studies of IPS with additional interventions were considered for inclusion. Conclusions. Six published studies were found which compared IPS alone to IPS plus a supplementary intervention. Of these, three used skills training and three used cognitive remediation. The contribution of each discrete intervention is difficult to establish. Some evidence suggests that work-related social skills and cognitive training are effective adjuncts, but this is an area where large RCTs are required to yield conclusive evidence.

  11. Nurturing educational research at Dartmouth Medical School: the synergy among innovative ideas, support faculty, and administrative structures. (United States)

    Nierenberg, David W; Carney, Patricia A


    In recent years, Dartmouth Medical School has increased its commitment to educational research within the school, and in collaboration with other schools across the country. Passionate faculty members with ideas and expertise in particular curricular areas are one critical component needed for a successful educational research program. Other components include an atmosphere that fosters research collaborations and mentoring, and various types of institutional support structures. This same model has effectively supported basic science and clinical research for decades. Because of the complexities involved in studying medical education, Dartmouth Medical School has invested in support structures for educational grant and manuscript development, financial support for pilot projects and partial salary support for investigators and key staff members, and other support targeted toward specific research projects. Ultimately, the goal is to use the results of the school's educational research projects to improve the curriculum through cycles of hypothesis development and testing, providing evidence for subsequent curricular change. When some research findings are relevant and applicable for use in other medical schools, that is an additional benefit of the educational research process. In this report, the authors describe the development of Dartmouth Medical School's infrastructure for supporting educational research, which has helped to accelerate the educational research productivity teaching faculty now enjoy. The authors also address some of the challenges that they anticipate in the near future.

  12. Postal administration compared with nurse-supported administration of the QUALEFFO-41 in a population sample: comparison of results and assessment of psychometric properties. (United States)

    Murrell, P; Todd, C J; Martin, A; Walton, J; Lips, P; Reeve, J


    The objective of this study was to test the psychometric properties of the QUALEFFO-41, an osteoporosis-specific health-related quality of life (HRQoL) measure, in a population sample. The study involved repeated administration of QUALEFFO-41 and another measure of HRQoL, the SF-36, to a stratified random population sample to test reliability and validity of instrument. The study was set in urban Harrow, Middlesex, UK and rural Cambridgeshire, UK. The participants were 83 males and 88 females aged 65-80+ years. Of the 230 individuals contacted 76.5% participated. The test-retest reliability of most QUALEFFO-41 items was good (Kappa 0.59-0.91) but two items had lower repeatability. Internal consistency was also generally good, but suggestive of some redundancy for three domains. The QUALEFFO-41 domains in general correlated well with SF-36 domains (r = 0.57 to r = 0.87), suggesting good validity. The QUALEFFO-41 has been shown to be a reliable and valid disease-specific HRQoL measure for osteoporosis. In population samples, it can be administered by post, or with a professional available to answer queries. Some specific items perform less well than may be desired and there is evidence of some redundancy, but further investigation is required and there are not yet grounds for textual change. We recommend continued use of this well-validated, reliable instrument.

  13. Anhedonia to music and mu-opioids: Evidence from the administration of naltrexone (United States)

    Mallik, Adiel; Chanda, Mona Lisa; Levitin, Daniel J.


    Music’s universality and its ability to deeply affect emotions suggest an evolutionary origin. Previous investigators have found that naltrexone (NTX), a μ-opioid antagonist, may induce reversible anhedonia, attenuating both positive and negative emotions. The neurochemical basis of musical experience is not well-understood, and the NTX-induced anhedonia hypothesis has not been tested with music. Accordingly, we administered NTX or placebo on two different days in a double-blind crossover study, and assessed participants’ responses to music using both psychophysiological (objective) and behavioral (subjective) measures. We found that both positive and negative emotions were attenuated. We conclude that endogenous opioids are critical to experiencing both positive and negative emotions in music, and that music uses the same reward pathways as food, drug and sexual pleasure. Our findings add to the growing body of evidence for the evolutionary biological substrates of music. PMID:28176798

  14. Anhedonia to music and mu-opioids: Evidence from the administration of naltrexone. (United States)

    Mallik, Adiel; Chanda, Mona Lisa; Levitin, Daniel J


    Music's universality and its ability to deeply affect emotions suggest an evolutionary origin. Previous investigators have found that naltrexone (NTX), a μ-opioid antagonist, may induce reversible anhedonia, attenuating both positive and negative emotions. The neurochemical basis of musical experience is not well-understood, and the NTX-induced anhedonia hypothesis has not been tested with music. Accordingly, we administered NTX or placebo on two different days in a double-blind crossover study, and assessed participants' responses to music using both psychophysiological (objective) and behavioral (subjective) measures. We found that both positive and negative emotions were attenuated.

Our findings add to the growing body of evidence for the evolutionary biological substrates of music.

  15. Runway self-administration of intracerebroventricular cocaine: evidence of mixed positive and negative drug actions. (United States)

    Guzman, Daniel; Ettenberg, Aaron


    In previous work from our laboratory, animals running for intravenous cocaine developed a unique approach-avoidance 'retreat behavior' that was hypothesized to result from cocaine's well documented reinforcing (positive) and anxiogenic (negative) properties. To assess the role of central mechanisms in producing cocaine's positive and negative effects, we assessed whether or not animals running a straight alley for intracerebroventricular applications of cocaine would produce a similar behavioral profile to that previously observed with intravenous applications. Retreat frequency and location were measured in male Sprague-Dawley rats trained to run an alley for one of four doses of intracerebroventricular-administered cocaine (0, 25, 50 or 100 microg cocaine/infusion). Testing involved a single trial per day over 14 consecutive days with a single infusion of cocaine delivered upon goal box entry. The 100 and 50 microg intracerebroventricular cocaine groups exhibited significantly higher retreat frequencies than the 25 and 0 microg groups and the nature and magnitude of the behavior was comparable to that previously observed with intravenous cocaine. These results suggest that the intracerebroventricular self-administration of cocaine results in mixed positive and negative consequences and therefore likely stem from the drug's actions within the central nervous system.

  16. A critical evaluation of the evidence supporting the practice of behavioural vision therapy. (United States)

    Barrett, Brendan T


    In 2000, the UK's College of Optometrists commissioned a report to critically evaluate the theory and practice of behavioural optometry. The report which followed Jennings (2000; Behavioural optometry--a critical review. Optom. Pract. 1: 67) concluded that there was a lack of controlled clinical trials to support behavioural management strategies. The purpose of this report was to evaluate the evidence in support of behavioural approaches as it stands in 2008. The available evidence was reviewed under 10 headings, selected because they represent patient groups/conditions that behavioural optometrists are treating, or because they represent approaches to treatment that have been advocated in the behavioural literature. The headings selected were: (1) vision therapy for accommodation/vergence disorders; (2) the underachieving child; (3) prisms for near binocular disorders and for producing postural change; (4) near point stress and low-plus prescriptions; (5) use of low-plus lenses at near to slow the progression of myopia; (6) therapy to reduce myopia; (7) behavioural approaches to the treatment of strabismus and amblyopia; (8) training central and peripheral awareness and syntonics; (9) sports vision therapy; (10) neurological disorders and neuro-rehabilitation after trauma/stroke. There is a continued paucity of controlled trials in the literature to support behavioural optometry approaches. Although there are areas where the available evidence is consistent with claims made by behavioural optometrists (most notably in relation to the treatment of convergence insufficiency, the use of yoked prisms in neurological patients, and in vision rehabilitation after brain disease/injury), a large majority of behavioural management approaches are not evidence-based, and thus cannot be advocated.

  17. Ascorbic acid administration produces an antidepressant-like effect: evidence for the involvement of monoaminergic neurotransmission. (United States)

    Binfaré, Ricardo W; Rosa, Angelo O; Lobato, Kelly R; Santos, Adair R S; Rodrigues, Ana Lúcia S


    Ascorbic acid is highly concentrated in the brain, being considered as a neuromodulator. This study investigated the effect of ascorbic acid in the tail suspension test (TST) and in the forced swimming test (FST) in mice and the contribution of the monoaminergic system to its antidepressant-like effect. Moreover, the effects of fluoxetine, imipramine and bupropion in combination with ascorbic acid in the TST were investigated. Ascorbic acid (0.1-10 mg/kg, i.p., 1-10 mg/kg p.o. or 0.1 nmol/mice i.c.v.) produced an antidepressant-like effect in the TST, but not in the FST, without altering the locomotor activity. The effect of ascorbic acid (0.1 mg/kg, i.p.) in the TST was prevented by i.p. pre-treatment with NAN-190 (0.5 mg/kg), ketanserin (5 mg/kg), MDL72222 (0.1 mg/kg), prazosin (62.5 microg/kg), yohimbine (1 mg/kg), propranolol (2 mg/kg), haloperidol (0.2 mg/kg), sulpiride (50 mg/kg), but not with SCH23390 (0.05 mg/kg, s.c.). Additionally, ascorbic acid (1 mg/kg, p.o.) potentiated the effect of subeffective doses (p.o. route) of fluoxetine (1 mg/kg), imipramine (0.1 mg/kg), or bupropion (1 mg/kg) in the TST. The combined treatment of ascorbic acid with antidepressants produced no alteration in the locomotion in the open-field test. In conclusion, our results show that administration of ascorbic acid produces an antidepressant-like effect in TST, which is dependent on its interaction with the monoaminergic system. Moreover, ascorbic acid caused a synergistic antidepressant-like effect with conventional antidepressants. Therefore, the present findings warrant further studies to evaluate the therapeutical relevance of ascorbic acid for the treatment of depression and as a co-adjuvant treatment with antidepressants.

  18. A Simple Network Management Architecture for Supporting Network Administrator and QoS Requirements

    CERN Document Server

    Phonphoem, Anan


    In this paper, a simple network management architecture for supporting both QoS requirements and organization network management policies is purposed. By grouping the traffic flows according to the QoS requirements or certain network management policies, the network resources are effectively controlled. The purposed architecture is easy to deploy; the gateway is the only equipment that needs installation, leaving the rest of the system untouched. The architecture has not significantly degraded the overall system utilization when applying it to the outgoing bound of the gateway. The architecture can also be implemented on the wireless LAN at the access point because the architecture is designed in such the way that it is independent to both the lower and upper protocol layers.

  19. Cancer Multidisciplinary Team Meetings: Evidence, Challenges, and the Role of Clinical Decision Support Technology

    Directory of Open Access Journals (Sweden)

    Vivek Patkar


    Full Text Available Multidisciplinary team (MDT model in cancer care was introduced and endorsed to ensure that care delivery is consistent with the best available evidence. Over the last few years, regular MDT meetings have become a standard practice in oncology and gained the status of the key decision-making forum for patient management. Despite the fact that cancer MDT meetings are well accepted by clinicians, concerns are raised over the paucity of good-quality evidence on their overall impact. There are also concerns over lack of the appropriate support for this important but overburdened decision-making platform. The growing acceptance by clinical community of the health information technology in recent years has created new opportunities and possibilities of using advanced clinical decision support (CDS systems to realise full potential of cancer MDT meetings. In this paper, we present targeted summary of the available evidence on the impact of cancer MDT meetings, discuss the reported challenges, and explore the role that a CDS technology could play in addressing some of these challenges.

  20. Social support, volunteering and health around the world: cross-national evidence from 139 countries. (United States)

    Kumar, Santosh; Calvo, Rocio; Avendano, Mauricio; Sivaramakrishnan, Kavita; Berkman, Lisa F


    High levels of social capital and social integration are associated with self-rated health in many developed countries. However, it is not known whether this association extends to non-western and less economically advanced countries. We examine associations between social support, volunteering, and self-rated health in 139 low-, middle- and high-income countries. Data come from the Gallup World Poll, an internationally comparable survey conducted yearly from 2005 to 2009 for those 15 and over. Volunteering was measured by self-reports of volunteering to an organization in the past month. Social support was based on self-reports of access to support from relatives and friends. We started by estimating random coefficient (multi-level) models and then used multivariate logistic regression to model health as a function of social support and volunteering, controlling for age, gender, education, marital status, and religiosity. We found statistically significant evidence of cross-national variation in the association between social capital variables and self-rated health. In the multivariate logistic model, self-rated health were significantly associated with having social support from friends and relatives and volunteering. Results from stratified analyses indicate that these associations are strikingly consistent across countries. Our results indicate that the link between social capital and health is not restricted to high-income countries but extends across many geographical regions regardless of their national-income level.

  1. Ocean Acidification and the End-Permian Mass Extinction: To What Extent does Evidence Support Hypothesis?

    Directory of Open Access Journals (Sweden)

    Marie-Béatrice Forel


    Full Text Available Ocean acidification in modern oceans is linked to rapid increase in atmospheric CO2, raising concern about marine diversity, food security and ecosystem services. Proxy evidence for acidification during past crises may help predict future change, but three issues limit confidence of comparisons between modern and ancient ocean acidification, illustrated from the end-Permian extinction, 252 million years ago: (1 problems with evidence for ocean acidification preserved in sedimentary rocks, where proposed marine dissolution surfaces may be subaerial. Sedimentary evidence that the extinction was partly due to ocean acidification is therefore inconclusive; (2 Fossils of marine animals potentially affected by ocean acidification are imperfect records of past conditions; selective extinction of hypercalcifying organisms is uncertain evidence for acidification; (3 The current high rates of acidification may not reflect past rates, which cannot be measured directly, and whose temporal resolution decreases in older rocks. Thus large increases in CO2 in the past may have occurred over a long enough time to have allowed assimilation into the oceans, and acidification may not have stressed ocean biota to the present extent. Although we acknowledge the very likely occurrence of past ocean acidification, obtaining support presents a continuing challenge for the Earth science community.

  2. Supporting evidence-based medicine: a survey of U.S. medical librarians. (United States)

    Li, Ping; Wu, Lin


    This study sought to identify medical librarians' roles in supporting evidence-based medicine (EBM) practice; determine whether medical librarians' work settings, work experiences, or job titles made a difference in their EBM responsibilities; and find out medical librarians' perceptions of their roles in EBM practice. An online survey was distributed to U.S. medical librarians. The results showed that medical librarians had positive perceptions of their EBM-related responsibilities, which were diverse and specific. Their work experience, work settings, and job title categories related to some of their EBM responsibilities, as well as the nature of some of the responsibilities.

  3. Evidence does not support absorption of intact solid lipid nanoparticles via oral delivery (United States)

    Hu, Xiongwei; Fan, Wufa; Yu, Zhou; Lu, Yi; Qi, Jianping; Zhang, Jian; Dong, Xiaochun; Zhao, Weili; Wu, Wei


    Whether and to what extent solid lipid nanoparticles (SLNs) can be absorbed integrally via oral delivery should be clarified because it is the basis for elucidation of absorption mechanisms. To address this topic, the in vivo fate of SLNs as well as their interaction with biomembranes is investigated using water-quenching fluorescent probes that can signal structural variations of lipid-based nanocarriers. Live imaging indicates prolonged retention of SLNs in the stomach, whereas in the intestine, SLNs can be digested quickly. No translocation of intact SLNs to other organs or tissues can be observed. The in situ perfusion study shows bioadhesion of both SLNs and simulated mixed micelles (SMMs) to intestinal mucus, but no evidence of penetration of integral nanocarriers. Both SLNs and SMMs exhibit significant cellular uptake, but fail to penetrate cell monolayers. Confocal laser scanning microscopy reveals that nanocarriers mainly concentrate on the surface of the monolayers, and no evidence of penetration of intact vehicles can be obtained. The mucous layer acts as a barrier to the penetration of both SLNs and SMMs. Both bile salt-decoration and SMM formulation help to strengthen the interaction with biomembranes. It is concluded that evidence does not support absorption of intact SLNs via oral delivery.Whether and to what extent solid lipid nanoparticles (SLNs) can be absorbed integrally via oral delivery should be clarified because it is the basis for elucidation of absorption mechanisms.

  4. Is there evidence that fresh frozen plasma is superior to antithrombin administration to treat heparin resistance in cardiac surgery? (United States)

    Beattie, Gwyn W; Jeffrey, Robert R


    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was, 'in [patients with heparin resistance] is [treatment with FFP] superior [to antithrombin administration] in [achieving adequate anticoagulation to facilitate safe cardiopulmonary bypass]?' More than 29 papers were found using the reported search, of which six represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Antithrombin (AT) binds to heparin and increases the rate at which it binds to thrombin. The levels of antithrombin in the blood are an important aspect of the heparin dose-response curve. When the activated clotting time (ACT) fails to reach a target >480, this is commonly defined as heparin resistance (HR). Heparin resistance is usually treated with a combination of supplementary heparin, fresh frozen plasma (FFP) or antithrombin III concentrate. There is a paucity of evidence on the treatment of heparin resistance with FFP, with only five studies identified, including one retrospective study, one in vitro trial and three case reports. AT has been studied more extensively with multiple studies, including a crossover trial comparing AT to supplemental heparin and a multicentre, randomized, double blind, placebo-controlled trial. Antithrombin (AT) concentrate is a safe and efficient treatment for heparin resistance to elevate the activated clotting time (ACT). It avoids the risk of transfusion-related acute lung injury (TRALI), volume overload, intraoperative time delay and viral or vCJD transmission. Antithrombin concentrates are more expensive than fresh frozen plasma and may put patients at risk of heparin rebound in the early postoperative period. Patients treated with AT have a lower risk of further FFP transfusions during their stay in hospital. We conclude that the treatment of

  5. Building an evidence-based multitiered system of supports for high-risk youth and communities. (United States)

    Kingston, Beverly E; Mihalic, Sharon F; Sigel, Eric J


    The mental, emotional and behavioral health problems of high-risk youth and youth living in high-risk communities are not inevitable and can be prevented. A shift from the nation's focus on treating disease and illness after it occurs to a concentrated effort on preventing the root causes of these problems is needed. Prevention science suggests a comprehensive multitiered approach that provides evidence-based prevention supports for children and youth at each developmental stage and across multiple social contexts is likely to result in the greatest health impact and return on investment. However, actually implementing this approach at a neighborhood level has remained a challenge and an ongoing research gap especially in high-risk communities. This article describes a process and provides a case study example for implementing a comprehensive, multitiered approach in a high-risk community. This includes assessing and prioritizing the specific needs of individuals and communities; selecting evidence-based programs based upon assessed needs; and creating a continuum of programs to improve the health and well-being of youth across developmental age spans, social contexts, and levels of risk. Operational details and challenges for organizing and implementing this comprehensive approach are also described. We estimate that the collective impact of a multitiered evidence-based approach, implemented with fidelity, could conservatively result in a 30 to 40% reduction in problem behaviors.

  6. Extracting physician group intelligence from electronic health records to support evidence based medicine.

    Directory of Open Access Journals (Sweden)

    Griffin M Weber

    Full Text Available Evidence-based medicine employs expert opinion and clinical data to inform clinical decision making. The objective of this study is to determine whether it is possible to complement these sources of evidence with information about physician "group intelligence" that exists in electronic health records. Specifically, we measured laboratory test "repeat intervals", defined as the amount of time it takes for a physician to repeat a test that was previously ordered for the same patient. Our assumption is that while the result of a test is a direct measure of one marker of a patient's health, the physician's decision to order the test is based on multiple factors including past experience, available treatment options, and information about the patient that might not be coded in the electronic health record. By examining repeat intervals in aggregate over large numbers of patients, we show that it is possible to 1 determine what laboratory test results physicians consider "normal", 2 identify subpopulations of patients that deviate from the norm, and 3 identify situations where laboratory tests are over-ordered. We used laboratory tests as just one example of how physician group intelligence can be used to support evidence based medicine in a way that is automated and continually updated.

  7. Current evidence does not support the use of Kinesio Taping in clinical practice: a systematic review

    Directory of Open Access Journals (Sweden)

    Patrícia do Carmo Silva Parreira


    Full Text Available Questions: Is Kinesio Taping more effective than a sham taping/placebo, no treatment or other interventions in people with musculoskeletal conditions? Is the addition of Kinesio Taping to other interventions more effective than other interventions alone in people with musculoskeletal conditions? Design: Systematic review of randomised trials. Participants: People with musculoskeletal conditions. Intervention: Kinesio Taping was compared with sham taping/placebo, no treatment, exercises, manual therapy and conventional physiotherapy. Outcome measures: Pain intensity, disability, quality of life, return to work, and global impression of recovery. Results: Twelve randomised trials involving 495 participants were included in the review. The effectiveness of the Kinesio Taping was tested in participants with: shoulder pain in two trials; knee pain in three trials; chronic low back pain in two trials; neck pain in three trials; plantar fasciitis in one trial; and multiple musculoskeletal conditions in one trial. The methodological quality of eligible trials was moderate, with a mean of 6.1 points on the 10-point PEDro Scale score. Overall, Kinesio Taping was no better than sham taping/placebo and active comparison groups. In all comparisons where Kinesio Taping was better than an active or a sham control group, the effect sizes were small and probably not clinically significant or the trials were of low quality. Conclusion: This review provides the most updated evidence on the effectiveness of the Kinesio Taping for musculoskeletal conditions. The current evidence does not support the use of this intervention in these clinical populations. PROSPERO registration: CRD42012003436.

  8. Sustained Implementation of Evidence-based Programs in Disadvantaged Communities: A Conceptual Framework of Supporting Factors. (United States)

    Hodge, Lauren M; Turner, Karen M T


    This paper presents a review of the empirical literature for studies evaluating factors that facilitate and create barriers to sustained program implementation in disadvantaged communities. It outlines study methodology and sustainment outcomes and proposes a conceptual model that involves implementation sustainment support for providers delivering evidence-based health and family services in disadvantaged communities. Sustained program implementation in the community setting is a significant issue as only 43% of studies reported successfully sustained programs. The review identified 18 factors that facilitate success and create barriers to program sustainment. The factors are synthesized into three themes; program characteristics, workplace capacity, and process and interaction factors. The majority of factors map onto commonly cited sustainability influences in implementation science. However, there was an additional focus for studies included in this review on the importance of factors such as program burden, program familiarity and perceived competence in program skills, workplace support for the program, staff mobility and turnover, supervision and peer support, and ongoing technical assistance. The need to use a conceptual framework and develop measures to guide and evaluate capacity building in EBP implementation and sustainment in low-resource community settings is highlighted.

However, there is a dearth of research focused on NM perspectives about institutional contextual factors to support the goal of EBP on the clinical unit. The purpose of this article is to identify contextual factors described by NMs to drive change and facilitate EBP at the unit level, comparing and contrasting these perspectives across nursing units. Methods: This study employed a qualitative descriptive design using interviews with nine NMs who were participating in a large effectiveness study. To stratify the sample, NMs were selected from nursing units designated as high or low performing based on implementation of EBP interventions, scores on the Meyer and Goes research use scale, and fall rates. Descriptive content analysis was used to identify themes that reflect the complex nature of infrastructure described by NMs and contextual influences that supported or hindered their promotion of EBP on the clinical unit. Results: NMs perceived workplace culture, structure, and resources as facilitators or barriers to empowering nurses under their supervision to use EBP and drive change. A workplace culture that provides clear communication of EBP goals or regulatory changes, direct contact with CEOs, and clear expectations supported NMs in their promotion of EBP on their units. High-performing unit NMs described a structure that included nursing-specific committees, allowing nurses to drive change and EBP from within the unit. NMs from high-performing units were more likely to articulate internal resources, such as quality

  10. Decision support for evidence-based pharmacotherapy detects adherence problems but does not impact medication use. (United States)

    Willis, Janese M; Edwards, Rex; Anstrom, Kevin J; Johnson, Fred S; Del Fiol, Guilherme; Kawamoto, Kensaku; Lapointe, Nancy M Allen; Eisenstein, Eric L; Lobach, David F


    Although evidence-based pharmacotherapies are a principal component of patient care, 30-50% of patients do not take their medications as prescribed. We conducted a randomized trial of two clinical decision support (CDS) interventions in 2219 patients: patient adherence reports to providers (n=744), patient adherence reports to providers + email notices to care managers (n=736), and controls (739). At 18-month follow-up, there were no treatment-related differences in patient medication adherence (overall, by medication class, and by medical condition). There also were no treatment-related differences in patient clinical and economic outcomes. Thus, while this study's CDS information interventions were successfully delivered to providers and care managers, and were effective in identifying medication adherence deficits and in increasing care manager responses to medication adherences issues, these interventions were not able to alter patient medication behavior.

  11. Support as a complement, intrusion and right--evidence from ageing and disability support service users in Sweden and Australia. (United States)

    Laragy, Carmel; Fisher, Karen R; Cedersund, Elisabet; Campbell-McLean, Carolyn


    How service users conceptualise their personal support services is under researched, even though this understanding is important for responsive policy development and service implementation. This paper tests the proposition that service users understand formal support in three ways: support is a complement to their other arrangements, an intrusion into their personal life and a right. These three concepts were identified using discourse analysis in a Swedish study of older people wanting in-home support services. To test generalisability of these concepts, they were applied to data from an Australian study of people using disability personal support. The analysis found that the three concepts were core to people's views of their support, although the construction of the concepts differed in the two countries. Service users in Sweden asserted their right to services more forcefully than those in Australia, and they had higher expectations that their support needs would be met. These differences reflect the impact of each country's social policy environment on service users' expectations. The analysis suggests that service users and their families want to control their formal support arrangements to complement their informal care and their life preferences and to minimise the intrusive aspects of formal support. The findings imply that the three concepts have utility for theorising service users' perspectives, informing policy and developing implementation strategies which enhance peoples' quality of life.

  12. Labor market effects of intrauterine exposure to nutritional deficiency: Evidence from administrative data on Muslim immigrants in Denmark. (United States)

    Schultz-Nielsen, Marie Louise; Tekin, Erdal; Greve, Jane


    This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual's labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of nutrients essential for fetal development. Specifically, we use administrative data from Denmark to investigate the impact of exposure to Ramadan in utero on labor market outcomes of adult Muslim males, including employment status, annual salary, hourly wage rate, and hours of work. Our findings indicate that potential exposure to nutritional disruptions during a critical stage of fetal development is likely to have scarring effects on the fetus expressed as poor labor market outcomes later in life. Specifically, exposure to Ramadan around the 7th month of gestation results in a lower likelihood of employment and, to a lesser extent, a lower salary, and reduced labor supply. For example, the 7th month intrauterine exposure to Ramadan is associated with a 2.6 percentage points reduction in the likelihood of employment among Muslim males. We do not find an impact on the wage rate. Finally, we also document suggestive evidence that these results may partially be driven by increased disability and to a lesser extent by poor educational attainment among those who were exposed to Ramadan during this particular period in utero.

    Sun, Gwo-Shing; Tou, Janet C; Yu, Diane; Girten, Beverly E; Cohen, Jacob


    Rodents have been the most frequently flown animal model used to study physiological responses to the space environment. In support of future of space exploration, the National Aeronautics and Space Administration (NASA) envisions an animal research program focused on rodents. Therefore, the development of a rodent diet that is suitable for the spaceflight environment including long duration spaceflight is a high priority. Recognizing the importance of nutrition in affecting spaceflight physiological responses and ensuring reliable biomedical and biological science return, NASA developed the nutrient-upgraded rodent food bar (NuRFB) as a standard diet for rodent spaceflight. Depending on future animal habitat hardware and planned spaceflight experiments, modification of the NuRFB or development of a new diet formulation may be needed, particularly for long term spaceflights. Research in this area consists primarily of internal technical reports that are not readily accessible. Therefore, the aims of this contribution are to provide a brief history of the development of rodent spaceflight diets, to review the present diet used in rodent spaceflight studies, and to discuss some of the challenges and potential solutions for diets to be used in future long-term rodent spaceflight studies.

  15. Evidence to Support the Anti-Cancer Effect of Olive Leaf Extract and Future Directions

    Directory of Open Access Journals (Sweden)

    Full Text Available The traditional Mediterranean diet (MD is associated with long life and lower prevalence of cardiovascular disease and cancers. The main components of this diet include high intake of fruit, vegetables, red wine, extra virgin olive oil (EVOO and fish, low intake of dairy and red meat. Olive oil has gained support as a key effector of health benefits and there is evidence that this relates to the polyphenol content. Olive leaf extract (OLE contains a higher quantity and variety of polyphenols than those found in EVOO. There are also important structural differences between polyphenols from olive leaf and those from olive fruit that may improve the capacity of OLE to enhance health outcomes. Olive polyphenols have been claimed to play an important protective role in cancer and other inflammation-related diseases. Both inflammatory and cancer cell models have shown that olive leaf polyphenols are anti-inflammatory and protect against DNA damage initiated by free radicals. The various bioactive properties of olive leaf polyphenols are a plausible explanation for the inhibition of progression and development of cancers. The pathways and signaling cascades manipulated include the NF-κB inflammatory response and the oxidative stress response, but the effects of these bioactive components may also result from their action as a phytoestrogen. Due to the similar structure of the olive polyphenols to oestrogens, these have been hypothesized to interact with oestrogen receptors, thereby reducing the prevalence and progression of hormone related cancers. Evidence for the protective effect of olive polyphenols for cancer in humans remains anecdotal and clinical trials are required to substantiate these claims idea. This review aims to amalgamate the current literature regarding bioavailability and mechanisms involved in the potential anti-cancer action of olive leaf polyphenols.

    Full Text Available With the functional demonstration of a role in erythrocyte invasion by Plasmodium falciparum parasites, implications in the aetiology of common conditions that prevail in individuals of African origin, and a wealth of pharmacological knowledge, the stimulatory G protein (Gs signal transduction pathway presents an exciting target for anti-malarial drug intervention. Having previously demonstrated a role for the G-alpha-s gene, GNAS, in severe malaria disease, we sought to identify other important components of the Gs pathway. Using meta-analysis across case-control and family trio (affected child and parental controls studies of severe malaria from The Gambia and Malawi, we sought evidence of association in six Gs pathway candidate genes: adenosine receptor 2A (ADORA2A and 2B (ADORA2B, beta-adrenergic receptor kinase 1 (ADRBK1, adenylyl cyclase 9 (ADCY9, G protein beta subunit 3 (GNB3, and regulator of G protein signalling 2 (RGS2. Our study amassed a total of 2278 cases and 2364 controls. Allele-based models of association were investigated in all genes, and genotype and haplotype-based models were investigated where significant allelic associations were identified. Although no significant associations were observed in the other genes, several were identified in ADORA2A. The most significant association was observed at the rs9624472 locus, where the G allele (approximately 20% frequency appeared to confer enhanced risk to severe malaria [OR = 1.22 (1.09-1.37; P = 0.001]. Further investigation of the ADORA2A gene region is required to validate the associations identified here, and to identify and functionally characterize the responsible causal variant(s. Our results provide further evidence supporting a role of the Gs signal transduction pathway in the regulation of severe malaria, and request further exploration of this pathway in future studies.

    Full Text Available Abstract Background The goal of this study is to extend research on evidence-based practice (EBP implementation by examining the impact of organizational type (public versus private and organizational support for EBP on provider attitudes toward EBP and EBP use. Both organization theory and theory of innovation uptake and individual adoption of EBP guide the approach and analyses in this study. We anticipated that private sector organizations would provide greater levels of organizational support for EBPs leading to more positive provider attitudes towards EBPs and EBP use. We also expected attitudes toward EBPs to mediate the association of organizational support and EBP use. Methods Participants were mental health service providers from 17 communities in 16 states in the United States (n = 170. Path analyses were conducted to compare three theoretical models of the impact of organization type on organizational support for EBP and of organizational support on provider attitudes toward EBP and EBP use. Results Consistent with our predictions, private agencies provided greater support for EBP implementation, and staff working for private agencies reported more positive attitudes toward adopting EBPs. Organizational support for EBP partially mediated the association of organization type on provider attitudes toward EBP. Organizational support was significantly positively associated with attitudes toward EBP and EBP use in practice. Conclusion This study offers further support for the importance of organizational context as an influence on organizational support for EBP and provider attitudes toward adopting EBP. The study demonstrates the role organizational support in provider use of EBP in practice. This study also suggests that organizational support for innovation is a malleable factor in supporting use of EBP. Greater attention should be paid to organizational influences that can facilitate the dissemination and implementation of EBPs in

  19. Historic evidence to support a causal relationship between spirochetal infections and Alzheimer's disease. (United States)

    Miklossy, Judith


    Following previous observations a statistically significant association between various types of spirochetes and Alzheimer's disease (AD) fulfilled Hill's criteria in favor of a causal relationship. If spirochetal infections can indeed cause AD, the pathological and biological hallmarks of AD should also occur in syphilitic dementia. To answer this question, observations and illustrations on the detection of spirochetes in the atrophic form of general paresis, which is known to be associated with slowly progressive dementia, were reviewed and compared with the characteristic pathology of AD. Historic observations and illustrations published in the first half of the 20th Century indeed confirm that the pathological hallmarks, which define AD, are also present in syphilitic dementia. Cortical spirochetal colonies are made up by innumerable tightly spiraled Treponema pallidum spirochetes, which are morphologically indistinguishable from senile plaques, using conventional light microscopy. Local brain amyloidosis also occurs in general paresis and, as in AD, corresponds to amyloid beta. These historic observations enable us to conclude that chronic spirochetal infections can cause dementia and reproduce the defining hallmarks of AD. They represent further evidence in support a causal relationship between various spirochetal infections and AD. They also indicate that local invasion of the brain by these helically shaped bacteria reproduce the filamentous pathology characteristic of AD. Chronic infection by spirochetes, and co-infection with other bacteria and viruses should be included in our current view on the etiology of AD. Prompt action is needed as AD might be prevented.

  20. Karyomegalic interstitial nephritis: further support for a distinct entity and evidence for a genetic defect. (United States)

    Spoendlin, M; Moch, H; Brunner, F; Brunner, W; Burger, H R; Kiss, D; Wegmann, W; Dalquen, P; Oberholzer, M; Thiel, G


    Karyomegalic interstitial nephritis was first described in 1979 by Mihatsch, who was reporting three such cases. We report here four additional cases as well as two family investigations. Our findings support the association of karyomegaly and interstitial nephritis as a distinct entity. Typical clinical features are asymptomatic progressive renal failure in the third decade of life and recurrent infections, mostly of the upper respiratory tract. Histologic alterations consist of markedly enlarged and hyperchromic nuclei in many tubular epithelial cells throughout the nephron accompanied by interstitial fibrosis in the surrounding atrophic tubules. Karyomegaly is not limited to the kidneys. In one case, autopsy revealed karyomegaly in epithelial and mesenchymal cells of many other organs. However, no association of karyomegaly with further histologic damage is evident except in the kidneys. Because of the familial clustering, karyomegalic interstitial nephritis seems to be an inherited disease. Examination of the nuclear proliferation-associated structures proliferating cell nuclear antigen/cyclin, Ki 67, and p53 suggests an inhibition of mitosis in karyomegalic cells. The finding of the same HLA haplotype, A9/B35, in four of six HLA-typed cases suggests the possibility of a genetic defect on chromosome 6, which is inherited and linked to the HLA locus.

    George Karavokiros


    Full Text Available While flood risk is evolving as one of the most imminent natural hazards and the shift from a reactive decision environment to a proactive one sets the basis of the latest thinking in flood management, the need to equip decision makers with necessary tools to think about and intelligently select options and strategies for flood management is becoming ever more pressing. Within this context, the Preparing for Extreme and Rare Events in Coastal Regions (PEARL intelligent knowledge-base (PEARL KB of resilience strategies is presented here as an environment that allows end-users to navigate from their observed problem to a selection of possible options and interventions worth considering within an intuitive visual web interface assisting advanced interactivity. Incorporation of real case studies within the PEARL KB enables the extraction of (evidence-based lessons from all over the word, while the KB’s collection of methods and tools directly supports the optimal selection of suitable interventions. The Knowledge-Base also gives access to the PEARL KB Flood Resilience Index (FRI tool, which is an online tool for resilience assessment at a city level available to authorities and citizens. We argue that the PEARL KB equips authorities with tangible and operational tools that can improve strategic and operational flood risk management by assessing and eventually increasing resilience, while building towards the strengthening of risk governance. The online tools that the PEARL KB gives access to were demonstrated and tested in the city of Rethymno, Greece.

    Peterson, Cynthia; Hodler, Juerg [Orthopaedic University Hospital of Balgrist, Radiology, Zuerich (Switzerland)


    This review article addresses the best evidence currently available for therapeutic injection therapy for conditions targeting the spine and sacroiliac joints. The article is presented by spinal region. Controversies and areas of interest for further studies are identified. There is conclusive evidence supporting the effectiveness of the caudal approach for the administration of epidural steroid injections for patients with low back pain from a variety of causes. In general, there is moderate-to-strong evidence supporting the use of transforaminal therapeutic epidural injections for lumbar nerve-root compression and facet injections for joint pain arising from these joints in the cervical, thoracic and lumbar spine, but further subgroup analysis is needed to help predict which specific patients may receive the most benefit from these procedures. No randomized controlled trials, meta-analyses or systematic reviews addressing the effectiveness of therapeutic sacroiliac joint injections have been found. For some injections, corticosteroids may not provide better outcomes compared to local anesthetic injections alone. (orig.)

    Directory of Open Access Journals (Sweden)



    Full Text Available The reform process of the state and implicitly of the public administration was a priority for the past governments of Romania. During 2004- 2009, within the reform process, the main actors involved in the coordination, implementation and monitoring of reform measures were: the Prime Minister, the Superior Council for Public Administration Reform, Public Policy Coordination and Structural Adjustment, the Ministry of Public Finance, the General Secretariat of Government, Ministry of Administration and Interior (renamed for a short time Ministry of Interior and Administrative Reform, the Central Unit for Public Administration Reform, National Institute of Administration, the National Agency of Civil Servants, and the National Modernizers Network. For evaluation of aspects related to the reform process it was designed a selective research within the members of the National Modernizers Network, for assessing their perception of the public administration reform undertaken by the institutions presented above. Evaluating their opinion can be an important point in the revitalization of the area of the administration reform process. Also, the research conducted aimed at assessing the degree of modernizers’ involvement in activities related to important aspects of the reform process: strategic planning, formulating and evaluating public policies, financial management, human resources management, decentralization, introduction of new information and communication technologies and administrative simplification.

    Stacey Dawn


    Full Text Available Abstract Background Management of cancer treatment-related symptoms is an important safety issue given that symptoms can become life-threatening and often occur when patients are at home. With funding from the Canadian Partnership Against Cancer, a pan-Canadian steering committee was established with representation from eight provinces to develop symptom protocols using a rigorous methodology (CAN-IMPLEMENT©. Each protocol is based on a systematic review of the literature to identify relevant clinical practice guidelines. Protocols were validated by cancer nurses from across Canada. The aim of this study is to build an effective and sustainable approach for implementing evidence-informed protocols for nurses to use when providing remote symptom assessment, triage, and guidance in self-management for patients experiencing symptoms while undergoing cancer treatments. Methods A prospective mixed-methods study design will be used. Guided by the Knowledge to Action Framework, the study will involve (a establishing an advisory knowledge user team in each of three targeted settings; (b assessing factors influencing nurses’ use of protocols using interviews/focus groups and a standardized survey instrument; (c adapting protocols for local use, ensuring fidelity of the content; (d selecting intervention strategies to overcome known barriers and implementing the protocols; (e conducting think-aloud usability testing; (f evaluating protocol use and outcomes by conducting an audit of 100 randomly selected charts at each of the three settings; and (g assessing satisfaction with remote support using symptom protocols and change in nurses’ barriers to use using survey instruments. The primary outcome is sustained use of the protocols, defined as use in 75% of the calls. Descriptive analysis will be conducted for the barriers, use of protocols, and chart audit outcomes. Content analysis will be conducted on interviews/focus groups and usability testing

    Directory of Open Access Journals (Sweden)

    Aislinn Conway


    Full Text Available Objective – To describe the self-perceived role of librarians in developing evidence based medicine (EBM curricula and identify their current and desired level of training to support these activities. Design – Multi-institutional qualitative study. Setting – Nine medical schools in Canada and the United States of America. Subjects – Nine librarians identified by medical school faculty as central to the provision of EBM training for medical students at their institution. Methods – The researchers designed a semi-structured interview schedule based on a review of the literature and their own experiences as librarians teaching EBM. The topics covered were; librarians’ perceptions of their roles in relation to the curriculum, the training required to enable them to undertake these roles, and their professional development needs. The interviews were conducted by telephone and then audio-recorded and transcribed verbatim. The authors present five main themes; curricular design, curricular deployment, curricular assessment, educational training, and professional development. Profiles were developed for each participant based on the latter two themes and from this information common characteristics were identified. Main Results – The participants described the importance of collaboration with faculty and student bodies when designing a curriculum. Information literacy instruction and specifically literature searching and forming a research question were taught by all of the participants to facilitate curricular deployment. Some of the librarians were involved or partly involved in curricular assessment activities such as formulating exam questions or providing feedback on assignments. Educational training of participants varied from informal observation to formal workshops offered by higher education institutions. All librarians indicated a willingness to partake in professional development focused on teaching and EBM. The subjects

    Directory of Open Access Journals (Sweden)

    Moynihan Ray


    Full Text Available Abstract Background Organizations have been established in many countries and internationally to support the use of research evidence by producing clinical practice guidelines, undertaking health technology assessments, and/or directly supporting the use of research evidence in developing health policy on an international, national, and state or provincial level. Learning from these organizations can reduce the need to 'reinvent the wheel' and inform decisions about how best to organize support for such organizations, particularly in low- and middle-income countries (LMICs. Methods We undertook a multi-method study in three phases – a survey, interviews, and case descriptions that drew on site visits – and in each of the second and third phases we focused on a purposive sample of those involved in the previous phase. We used the seven main recommendations that emerged from the advice offered in the interviews to organize much of the synthesis of findings across phases and methods. We used a constant comparative method to identify themes from across phases and methods. Results Seven recommendations emerged for those involved in establishing or leading organizations that support the use of research evidence in developing health policy: 1 collaborate with other organizations; 2 establish strong links with policymakers and involve stakeholders in the work; 3 be independent and manage conflicts of interest among those involved in the work; 4 build capacity among those working in the organization; 5 use good methods and be transparent in the work; 6 start small, have a clear audience and scope, and address important questions; and 7 be attentive to implementation considerations, even if implementation is not a remit. Four recommendations emerged for the World Health Organization (WHO and other international organizations and networks: 1 support collaborations among organizations; 2 support local adaptation efforts; 3 mobilize support; and 4 create

  10. New sedimentological evidence supporting a catastrophic meltwater discharge event along the Beaufort margin, Arctic Ocean (United States)

    Klotsko, S.; Driscoll, N. W.; Keigwin, L. D.; Mendenhall, B.


    In 2013, a cruise on the USCGC Healy mapped the Beaufort margin from Barrow, AK into the Amundsen Gulf using a towed CHIRP subbottom profiler and a hull-mounted Knudsen CHIRP subbottom profiler to study the deglaciation of the margin. Sediment cores were also acquired. New grain size analyses for three sediment cores will be presented. These records help constrain the flooding events captured in the existing grain size data from JPC 15, just east of the Mackenzie trough. This core shows evidence of multiple ice rafted debris events that were likely sourced from the retreat of the Amundsen ice stream. These layers have peaks in grain size around ~20 microns compared to the ~5 micron average for the rest of the core. The grain size peaks correlate to the high amplitude reflectors observed in the seismic CHIRP data. Similar reflectors are observed in the seismic data from two of the new core locations, one in the Mackenzie trough and one east of the trough. The seismic data from these stations also record a thick sediment package that is ~7 meters thick at its depocenter. This layer is interpreted to record a massive meltwater discharge event that entered the Arctic via the Mackenzie River. Oxygen isotope data from JPC 15 support an event at this location based on the covarying benthic and planktonic records. In our conceptual model, the pulses of freshwater from the Amundsen Gulf likely freshened the margin sufficiently that the major discharge event was then able to push the system over the edge. This catastrophic glacial lake draining out the Mackenzie River into the Beaufort Sea and export out of the Arctic into the North Atlantic caused diminished meridional overturning circulation - slowing of the conveyor belt thermohaline circulation - which, in turn, potentially caused the Younger Dryas cold period.

  14. Coherence of evidence from systematic reviews as a basis for evidence strength - a case study in support of an epistemological proposition

    Directory of Open Access Journals (Sweden)

    Mickenautsch Steffen


    Full Text Available Abstract Background This article aims to offer, on the basis of Coherence theory, the epistemological proposition that mutually supportive evidence from multiple systematic reviews may successfully refute radical, philosophical scepticism. Methods A case study including seven systematic reviews is presented with the objective of refuting radical philosophical scepticism towards the belief that glass-ionomer cements (GIC are beneficial in tooth caries therapy. The case study illustrates how principles of logical and empirical coherence may be applied as evidence in support of specific beliefs in healthcare. Results The results show that radical scepticism may epistemologically be refuted on the basis of logical and empirical coherence. For success, several systematic reviews covering interconnected beliefs are needed. In praxis, these systematic reviews would also need to be of high quality and its conclusions based on reviewed high quality trials. Conclusions A refutation of radical philosophical scepticism to clinical evidence may be achieved, if and only if such evidence is based on the logical and empirical coherence of multiple systematic review results. Practical application also requires focus on the quality of the systematic reviews and reviewed trials.

  15. Legalising medical use of cannabis in South Africa: Is the empirical evidence sufficient to support policy shifts in this direction? (United States)

    Parry, Charles D H; Myers, Bronwyn J


    Inkatha Freedom Party MP Mario Oriani-Ambrosini's impassioned plea to legalise the medical use of cannabis must be understood in the context of his own condition as well as legislative changes in at least ten countries. This article argues that any decisions to shift policy must be based on a consideration of the evidence on the risks and benefits associated with the medical use of cannabis for the individual and broader society. It concludes that there are important gaps in the evidence base, particularly in human trials supporting the efficacy of cannabis use for treating and preventing medical conditions and alleviating negative symptoms associated with these conditions. South African researchers should be enabled actively to support development of the necessary evidence base actively by conducting preclinical and clinical research in this area. Human trials to establish the efficacy of the use of cannabis/cannabinoids in addressing AIDS wasting syndrome and other negative sequelae of HIV and AIDS are especially needed.

  17. Research to support evidence-based practice in COPD community nursing. (United States)

    Kirkpatrick, Pamela; Wilson, Ethel; Wimpenny, Peter


    Evidence-based practice (EBP) is a requirement of nurses through the generation of evidence to implementing it, in a bid to to improve clinical practice. However, EBP is difficult to achieve. This paper highlights an approach to generating evidence for enhancing community nursing services for patients with chronic obstructive pulmonary disease (COPD) through a collaborative partnership. A district nurse and two nursing lecturers formed a partnership to devise a systematic review protocol and perform a systematic review to enhance COPD practice. This paper illustrates the Joanna Briggs Institute (JBI) systematic review process, the review outcomes and the practitioner learning. Collaborative partnerships between academics, researchers and clinicians are a potentially useful model to facilitate enhanced outcomes in evidence-based practice and evidence application.

  19. Marriage Squeeze and Intergenerational Support in Contemporary Rural China: Evidence from X County of Anhui Province. (United States)

    Jin, Xiaoyi; Guo, Qiuju; Feldman, Marcus W


    With China's gender imbalance and increasingly severe male marriage squeeze, patterns of intergenerational support in rural areas are likely to undergo significant change. Using data from a survey of four towns from X county in Anhui province carried out in 2008, this article analyzes the effects of sons' marital status on intergenerational support. Random-effect regression analysis shows that son's marital status has strong effects on financial support to and coresidence with parents. Compared with married sons, older unmarried sons (so-called forced bachelors) tend to provide less financial support to their parents and are more likely to live with their parents. Parents' support of sons, as well as the parents' own needs and sons' capabilities all affect the support provided by sons. These results show that both theories of exchange and altruism are simultaneously relevant in the context of the marriage squeeze of contemporary rural China.

  20. Discovering the dementia evidence base: Tools to support knowledge to action in dementia care (innovative practice). (United States)

    Hayman, Sarah L; Tieman, Jennifer J


    Dementia requires expert care and decision making, based on sound evidence. Reliable evidence is difficult for busy dementia care professionals to find quickly. This study developed an experimentally tested search filter as an innovative tool to retrieve literature on dementia. It has a known retrieval performance and can be provided as an open access web link directly to current literature. The Dementia Search Filter was developed using validated methodology. An Expert Advisory Group of dementia care practitioners and researchers ratified a representative set of relevant studies and undertook post hoc relevance assessment, to ensure the usefulness of the search filter. The Dementia Search Filter is published on two websites and combined with expert searches to link to evidence on dementia, at end of life in aged care settings and more generally. Evidence accessed by the Dementia Search Filter will help overcome barriers to finding current relevant research in the field, for practitioners, researchers and decision makers.

  2. Intranasal administration as a route for drug delivery to the brain: evidence for a unique pathway for albumin. (United States)

    Falcone, Joseph A; Salameh, Therese S; Yi, Xiang; Cordy, Benjamin J; Mortell, William G; Kabanov, Alexander V; Banks, William A


    A variety of compounds will distribute into the brain when placed at the cribriform plate by intranasal (i.n.) administration. In this study, we investigated the ability of albumin, a protein that can act as a drug carrier but is excluded from brain by the blood-brain barrier, to distribute into the brain after i.n. administration. We labeled bovine serum albumin with [(125)I] ([(125)I]Alb) and studied its uptake into 11 brain regions and its entry into the blood from 5 minutes to 6 hours after i.n. administration. [(125)I]Alb was present throughout the brain at 5 minutes. Several regions showed distinct peaks in uptake that ranged from 5 minutes (parietal cortex) to 60 minutes (midbrain). About 2-4% of the i.n. [(125)I]Alb entered the bloodstream. The highest levels occurred in the olfactory bulb and striatum. Distribution was dose-dependent, with less taken up by whole brain, cortex, and blood at the higher dose of albumin. Uptake was selectively increased into the olfactory bulb and cortex by the fluid-phase stimulator PMA (phorbol 12-myristate 13-acetate), but inhibitors to receptor-mediated transcytosis, caveolae, and phosphoinositide 3-kinase were without effect. Albumin altered the distribution of radioactive leptin given by i.n. administration, decreasing uptake into the blood and by the cerebellum and increasing uptake by the hypothalamus. We conclude that [(125)I]Alb administered i.n. reaches all parts of the brain through a dose-dependent mechanism that may involve fluid-phase transcytosis and, as illustrated by leptin, can affect the delivery of other substances to the brain after their i.n. administration.

  5. Gender, social support, and well-being: Evidence from a Greek community sample

    Directory of Open Access Journals (Sweden)

    Konstantinos Kafetsios


    Full Text Available The importance of social support for psychological well-being has been aptly highlighted in epidemiological and psychological research. However, it is not clear from the existing research whether gender differences in structural (relationship status, network size, frequency of interactions with friends and functional (support satisfaction aspects of social support exist and -if they do- to what extent they affect males’ and females’ well-being. Hierarchical regression analyses of crossectional data from a Greek community sample showed that support satisfaction was an important predictor of well-being outcomes in males whereas several structural indicators were predictors of different well-being outcomes in females. Females’ anxiety, perceived stress, and loneliness were adversely affected by frequency of interaction with acquaintances. The results are discussed with regard to gender-role differences that may be underlying the social support effects on well-being, as well as related cultural values.

    This paper examines the influence of the national health insurance scheme on elderly demand for family-based care and support. It contributes to the growing concern on the rapid increase in the elderly population globally using micro-level social theory to examine the influence the health insurance has on elderly demand for family support. A qualitative case study approach is applied to construct a comprehensive and thick description of how the national health insurance scheme influences the elderly in their demand for family support.Through focused interviews and direct observation of six selected cases, in-depth information on primary carers, living arrangement and the interaction between the health insurance as structure and elders as agents are analyzed. The study highlights that the interaction between the elderly and the national health insurance scheme has produced a new stratum of relationship between the elderly and their primary carers. Consequently, this has created equilibrium between the elderly demand for support and support made available by their primary carers. As the demand of the elderly for support is declining, supply of support by family members for the elderly is also on the decline.

  9. [Online information service: the library support for evidence-based practice]. (United States)

    Markulin, Helena; Petrak, Jelka


    It frequently happens that physicians do not have adequate skills or enough time for searching and evaluating evidence needed in their everyday practice. Medical librarian can serve as a mediator in enabling physicians to utilize the potential offered by contemporary evidence-based medicine. The Central Medical Library (CML) at University of Zagreb, School of Medicine, designed a web-based information service aimed at the promotion of evidence-based practice in the Croatian medical community. The users can ask for a help in finding information on their clinical problems. A responsible librarian will analyse the problem, search information resources and evaluate the evidence. The answer is returned to the user by an e-mail. In the 2008-2012 period 166 questions from 12 clinical fields were received and most of them (36.1%) came from internal medicine doctors. The share of treatment-related questions was 70.5%. In the setting of underdeveloped ICT infrastructure and inadequate EBM resources availability, such information service can help in transfer of scientific evidence into the everyday clinical practice.

  10. Danish evidence-based clinical guideline for use of nutritional support in pulmonary rehabilitation of undernourished patients with stable COPD

  11. Executive summary: evaluation of the evidence to support practice guidelines for nutritional care of preterm infants-the Pre-B Project. (United States)

    Raiten, Daniel J; Steiber, Alison L; Hand, Rosa K


    Preterm birth (infants born at States and globally. No universally accepted practice guidelines exist for the nutritional care of preterm infants. To address the current state of knowledge and to support systematic reviews that will be used to develop evidence-informed guidance, a consortium consisting of the American Academy of Pediatrics, the ASN, the American Society for Parenteral and Enteral Nutrition, the Academy of Nutrition and Dietetics, the Food and Drug Administration, the CDC, the USDA/Agricultural Research Service (USDA/ARS), and the Eunice Kennedy Shriver National Institute of Child Health and Human Development/NIH initiated the Pre-B Project. The project included the constitution of 4 thematic working groups charged with the following tasks: 1) develop a series of topics/questions for which there is sufficient evidence to support a systematic review process to be conducted by the Academy of Nutrition and Dietetics' Evidence Analysis Library (EAL), leading to the development of new guidelines for nutritional care of preterm infants, and 2) develop a targeted research agenda to address priority gaps in our understanding of the role of nutrition in the health and development of preterm/neonatal intensive care unit infants. This review consists of a project overview including a summary of a workshop hosted by the USDA/ARS Children's Nutrition Research Center and summary reports of the 4 working groups established to address the following themes: 1) nutrient specifications, 2) clinical/practical issues in enteral feeding, 3) gastrointestinal and surgical issues, and 4) current standards for assessing infant feeding outcomes. These reports will serve as the basis for the ultimate guideline development process to be conducted by the Academy of Nutrition and Dietetics' EAL.

    违法行政行为造成当事人损害后果的,行政机关应当承担行政赔偿责任,这是行政赔偿诉讼的基本要义。法院以行政机关逾期未举证为由判决撤销行政行为,由此引发的行政赔偿诉讼中,判断行政机关是否应当对损害后果承担赔偿责任,与一般行政违法情形下的行政赔偿诉讼不同,需要具体分析辨别。人民法院以被告行政机关未在法定期限内提供证据、依据为由判决撤销行政行为,当事人依据该判决提起行政赔偿诉讼的,人民法院应审查认定行政行为是否实际存在违法情形,据此进行因果关系判断,得出当事人的赔偿主张是否成立的判决结论;人民法院对行政行为是否违法的审查强度,以“谁主张谁举证”原则,根据优势证据进行审查认定为宜。%When illegal administrative behavior causes the consequences of the damage to the party, the ad-ministrative organs should assume the liabilities for administrative compensation, which is the basic meaning of administrative compensation litigation. Different from common cases concerning administrative compensa-tions, careful scrutiny over detailed conditions is needed to judge whether administrative organs should be li-able on occasions where the court cancels the case for lack of proper evidence in due time. When the people's court brings in a verdict of revoking administrative action on the grounds of the defendant administrative organ failing to provide evidence within the statutory time limit, as long as the litigant takes an administrative com-pensation legal action based on that judgment, the people's court should investigate and identify whether ad-ministrative action actually breaks the law or not, and then makes causality judgment. In accordance with the conclusion, the court makes the decision of judgment whether the compensation the litigant asking for should be supported. The people's court's strength of

  19. Current Evidence Supporting the Link Between Dietary Fatty Acids and Cardiovascular Disease. (United States)

    Hammad, Shatha; Pu, Shuaihua; Jones, Peter J


    Lack of consensus exists pertaining to the scientific evidence regarding effects of various dietary fatty acids on cardiovascular disease (CVD) risk. The objective of this article is to review current evidence concerning cardiovascular health effects of the main dietary fatty acid types; namely, trans (TFA), saturated (SFA), polyunsaturated (PUFA; n-3 PUFA and n-6 PUFA), and monounsaturated fatty acids (MUFA). Accumulating evidence shows negative health impacts of TFA and SFA; both may increase CVD risk. Policies have been proposed to reduce TFA and SFA consumption to less than 1 and 7 % of energy intake, respectively. Cardiovascular health might be promoted by replacing SFA and TFA with n-6 PUFA, n-3 PUFA, or MUFA; however, the optimal amount of PUFA or MUFA that can be used to replace SFA and TFA has not been defined yet. Evidence suggests of the potential importance of restricting n-6 PUFA up to 10 % of energy and obtaining an n-6/n-3 ratio as close as possible to unity, along with a particular emphasis on consuming adequate amounts of essential fatty acids. The latest evidence shows cardioprotective effects of MUFA-rich diets, especially when MUFA are supplemented with essential fatty acids; namely, docosahexaenoic acid. MUFA has been newly suggested to be involved in regulating fat oxidation, energy metabolism, appetite sensations, weight maintenance, and cholesterol metabolism. These favorable effects might implicate MUFA as the preferable choice to substitute for other fatty acids, especially given the declaration of its safety for up to 20 % of total energy.

  20. Community Support and Adolescent Girls' Vulnerability to HIV/AIDS: Evidence From Botswana, Malawi, and Mozambique. (United States)

    Underwood, Carol; Schwandt, Hilary M


    Girls are vulnerable to HIV in part because the social systems in which they live have failed to support and protect them. The goal of this research was to develop a viable supportive community index and test its association with intermediate variables associated with HIV risk across 16 communities in Botswana, Malawi, and Mozambique. This cross-sectional survey with separate samples randomly drawn in each country (2010) yielded a total sample of 1,418 adolescent girls (aged 11-18). Multilevel, multivariate logistic regression, while controlling for vulnerability, age, religion, and residence, found that an increase in supportive community index is positively associated with the odds of indicating improved community support for girls and with the confidence to refuse unwanted sex with a boyfriend across the three countries, as well as with self-efficacy to insist on condom use in Botswana and Mozambique. Program implementers and decision makers alike can use the supportive community index to identify and measure structural factors associated with girls' vulnerability to HIV/AIDS; this will potentially contribute to judicious decision making regarding resource allocation to enhance community-level, protective factors for adolescent girls.

  1. Sources of support for learning words in conversation: evidence from mealtimes. (United States)

    Beals, D E


    This study examines mealtimes of preschoolers' families to determine whether rare words are used in informative ways so that a child could learn their meanings. Is there an association between informative use of rare words and the child's later vocabulary? Each use of rare words in 160 transcripts was coded for whether it was informative or uninformative. Each informative exchange was coded for type of strategy used to provide support: physical or social context, prior knowledge, and semantic support. There were 1,631 exchanges around rare words. About two-thirds of these exchanges were informative uses from which the child could learn the word's meaning. The most frequent strategy used was semantic support, accounting for two-thirds of strategies used. The frequency of use of rare words was positively correlated with age-five and age-seven PPVT scores.

  2. Fostering integrity in postgraduate research: an evidence-based policy and support framework. (United States)

    Mahmud, Saadia; Bretag, Tracey


    Postgraduate research students have a unique position in the debate on integrity in research as students and novice researchers. To assess how far policies for integrity in postgraduate research meet the needs of students as "research trainees," we reviewed online policies for integrity in postgraduate research at nine particular Australian universities against the Australian Code for Responsible Conduct of Research (the Code) and the five core elements of exemplary academic integrity policy identified by Bretag et al. (2011 ), i.e., access, approach, responsibility, detail, and support. We found inconsistency with the Code in the definition of research misconduct and a lack of adequate detail and support. Based on our analysis, previous research, and the literature, we propose a framework for policy and support for postgraduate research that encompasses a consistent and educative approach to integrity maintained across the university at all levels of scholarship and for all stakeholders.

    Meneses, Karen; Holland, Aimee Chism


    Approximately 6% of invasive breast cancer is diagnosed in women younger than age 40 of age childbearing potential. Cancer-directed therapies can cause hormonal and anatomical changes that negatively affect the reproductive potential of young survivors of breast cancer. Recent national guidelines on fertility preservation are widely available. However, gaps in care exist in the interdisciplinary evidence-based management of young survivors of breast cancer with fertility and parenting concerns after cancer treatment.

  8. Asset Management Planning – providing the evidence to support robust and risk-based investment decisions

    Directory of Open Access Journals (Sweden)

    Mitchell Chrissy


    Full Text Available Over the last decade the UK’s joint Flood and Coastal Erosion Risk Management Research and Development programme has been developing methods to support a move to a risk-based approach to flood defence asset management. Looking to ensure investment is less ‘find and fix’ and made to those assets where the biggest risk reduction can be made for the money available. In addition, providing the capability to articulate the benefits of investing in these assets quantitatively and transparently. This paper describes how the Asset Performance Tools (APT project [1] is delivering practical methods, prototype tools and supporting guidance which, together with related initiatives such as the Environment Agency’s Creating Asset Management Capacity (CAMC strategic programme [2] and the ‘State of the Nation’ (SoN [3] supportive datasets, will enable a risk-based, ‘predict and protect’ approach to asset management. A key advance is the ability to bring in local knowledge to make national generic datasets locally relevant. The paper also highlights existing outputs that can already be used to support a more proactive approach to asset management. It will summarise the ongoing work which will further develop and fine tune performance assessment and investment decision processes within an integrated conceptual framework aligned with ISO55000, deliverable via CAMC and whose concepts can be used by all risk management authorities.

  11. Do knowledge infrastructure facilities support Evidence-Based Practice in occupational health? An exploratory study across countries among occupational physicians enrolled on Evidence-Based Medicine courses

    Directory of Open Access Journals (Sweden)

    van Dijk Frank JH


    Full Text Available Abstract Background Evidence-Based Medicine (EBM is an important method used by occupational physicians (OPs to deliver high quality health care. The presence and quality of a knowledge infrastructure is thought to influence the practice of EBM in occupational health care. This study explores the facilities in the knowledge infrastructure being used by OPs in different countries, and their perceived importance for EBM practice. Methods Thirty-six OPs from ten countries, planning to attend an EBM course and to a large extent recruited via the European Association of Schools of Occupational Medicine (EASOM, participated in a cross-sectional study. Results Research and development institutes, and knowledge products and tools are used by respectively more than 72% and more than 80% of the OPs and they are rated as being important for EBM practice (more than 65 points (range 0–100. Conventional knowledge access facilities, like traditional libraries, are used often (69% but are rated as less important (46.8 points (range 0–100 compared to the use of more novel facilities, like question-and-answer facilities (25% that are rated as more important (48.9 points (range 0–100. To solve cases, OPs mostly use non evidence-based sources. However, they regard the evidence-based sources that are not often used, e.g. the Cochrane library, as important enablers for practising EBM. The main barriers are lack of time, payment for full-text articles, language barrier (most texts are in English, and lack of skills and support. Conclusion This first exploratory study shows that OPs use many knowledge infrastructure facilities and rate them as being important for their EBM practice. However, they are not used to use evidence-based sources in their practice and face many barriers that are comparable to the barriers physicians face in primary health care.

  12. Evidence of human papillomavirus vaccine effectiveness in reducing genital warts: an analysis of California public family planning administrative claims data, 2007-2010. (United States)

    Bauer, Heidi M; Wright, Glenn; Chow, Joan


    Because of the rapid development of genital warts (GW) after infection, monitoring GW trends may provide early evidence of population-level human papillomavirus (HPV) vaccine effectiveness. Trends in GW diagnoses were assessed using public family planning administrative data. Between 2007 and 2010, among females younger than 21 years, these diagnoses decreased 35% from 0.94% to 0.61% (P(trend) < .001). Decreases were also observed among males younger than 21 years (19%); and among females and males ages 21-25 (10% and 11%, respectively). The diagnoses stabilized or increased among older age groups. HPV vaccine may be preventing GW among young people.

  13. Spectroscopic evidence for origins of size and support effects on selectivity of Cu nanoparticle dehydrogenation catalysts

    Energy Technology Data Exchange (ETDEWEB)

    Witzke, M. E.; Dietrich, P. J.; Ibrahim, M. Y. S.; Al-Bardan, K.; Triezenberg, M. D.; Flaherty, D. W.


    Selective dehydrogenation catalysts that produce acetaldehyde from bio-derived ethanol can increase the efficiency of subsequent processes such as C–C coupling over metal oxides to produce 1-butanol or 1,3-butadiene or oxidation to acetic acid. Here, we use in situ X-ray absorption spectroscopy and steady state kinetics experiments to identify Cuδ+ at the perimeter of supported Cu clusters as the active site for esterification and Cu0 surface sites as sites for dehydrogenation. Correlation of dehydrogenation and esterification selectivities to in situ measures of Cu oxidation states show that this relationship holds for Cu clusters over a wide-range of diameters (2–35 nm) and catalyst supports and reveals that dehydrogenation selectivities may be controlled by manipulating either.

    Johnson, Evan; Sanger, Joseph; Rosenkrantz, Andrew B


    A departmental tool that provides a digital/administrative solution for communication of important imaging findings was evaluated. The tool allows the radiologist to click a button to mark an examination for ordering physician follow-up with subsequent fax and confirmation. The tool's log was reviewed. Of 466 entries; 99.4% were successfully faxed with phone confirmation. Most common reasons for usage were lung nodule/mass (29.2%) and osseous fracture (12.4%). Subsequent clinical action was documented in 41.0% of entries. Our data show the reliability of the tool in assisting the communication of findings, as well as providing documentation of notification, with minimal workflow disruption.

  16. Biological evidence supports an early and complex emergence of the Isthmus of Panama. (United States)

    Bacon, Christine D; Silvestro, Daniele; Jaramillo, Carlos; Smith, Brian Tilston; Chakrabarty, Prosanta; Antonelli, Alexandre


    The linking of North and South America by the Isthmus of Panama had major impacts on global climate, oceanic and atmospheric currents, and biodiversity, yet the timing of this critical event remains contentious. The Isthmus is traditionally understood to have fully closed by ca. 3.5 million years ago (Ma), and this date has been used as a benchmark for oceanographic, climatic, and evolutionary research, but recent evidence suggests a more complex geological formation. Here, we analyze both molecular and fossil data to evaluate the tempo of biotic exchange across the Americas in light of geological evidence. We demonstrate significant waves of dispersal of terrestrial organisms at approximately ca. 20 and 6 Ma and corresponding events separating marine organisms in the Atlantic and Pacific oceans at ca. 23 and 7 Ma. The direction of dispersal and their rates were symmetrical until the last ca. 6 Ma, when northern migration of South American lineages increased significantly. Variability among taxa in their timing of dispersal or vicariance across the Isthmus is not explained by the ecological factors tested in these analyses, including biome type, dispersal ability, and elevation preference. Migration was therefore not generally regulated by intrinsic traits but more likely reflects the presence of emergent terrain several millions of years earlier than commonly assumed. These results indicate that the dramatic biotic turnover associated with the Great American Biotic Interchange was a long and complex process that began as early as the Oligocene-Miocene transition.

  17. Intracranial volume and dementia: some evidence in support of the cerebral reserve hypothesis. (United States)

    Tate, D F; Neeley, E S; Norton, M C; Tschanz, J T; Miller, M J; Wolfson, L; Hulette, C; Leslie, C; Welsh-Bohmer, K A; Plassman, B; Bigler, Erin D


    The brain reserve hypothesis has been posited as being one important mediating factor for developing dementia, especially Alzheimer's disease (AD). Evidence for this hypothesis is mixed though different methodologies have made these findings difficult to interpret. We examined imaging data from a large cohort (N=194) of mixed dementia patients and controls, 65years old and older from the Cache County, Utah Study of Memory and Aging for evidence of the brain reserve hypothesis using total intracranial volume (TICV) as a quantitative measure of pre-morbid brain size and a vicarious indicator of reserve. A broader spectrum of non-demented elderly control subjects from previous studies was also included for comparison (N=423). In addition, non-parametric Classification and Regression Tree (CART) analyses were performed to model group heterogeneity and identify any subgroups of patients where TICV might be an important predictor of dementia. Parametrically, no main effect was found for TICV when predicting a dementia diagnosis; however, the CART analysis did reveal important TICV subgroups, including a sex differential wherein ε4 APOE allele presence in males and low TICV predicted AD classification. TICV, APOE, and other potential mediator/moderator variables are discussed in the context of the brain reserve hypothesis.

  19. Further Evidence in Support of the Universal Nilpotent Grammatical Computational Paradigm of Quantum Physics (United States)

    Marcer, Peter J.; Rowlands, Peter


    Further evidence is presented in favour of the computational paradigm, conceived and constructed by Rowlands and Diaz, as detailed in Rowlands' book Zero to Infinity (2007) [2], and in particular the authors' paper `The Grammatical Universe: the Laws of Thermodynamics and Quantum Entanglement' [1]. The paradigm, which has isomorphic group and algebraic quantum mechanical language interpretations, not only predicts the well-established facts of quantum physics, the periodic table, chemistry / valence and of molecular biology, whose understanding it extends; it also provides an elegant, simple solution to the unresolved quantum measurement problem. In this fundamental paradigm, all the computational constructs / predictions that emerge, follow from the simple fact, that, as in quantum mechanics, the wave function is defined only up to an arbitrary fixed phase. This fixed phase provides a simple physical understanding of the quantum vacuum in quantum field theory, where only relative phases, known to be able to encode 3+1 relativistic space-time geometries, can be measured. It is the arbitrary fixed measurement standard, against which everything that follows is to be measured, even though the standard itself cannot be, since nothing exists against which to measure it. The standard, as an arbitrary fixed reference phase, functions as the holographic basis for a self-organized universal quantum process of emergent novel fermion states of matter where, following each emergence, the arbitrary standard is re-fixed anew so as to provide a complete history / holographic record or hologram of the current fixed past, advancing an unending irreversible evolution, such as is the evidence of our senses. The fermion states, in accord with the Pauli exclusion principle, each correspond to a unique nilpotent symbol in the infinite alphabet (which specifies the grammar in this nilpotent universal computational rewrite system (NUCRS) paradigm); and the alphabet, as Hill and Rowlands

  20. Where is the evidence supporting public service announcements to eliminate mental illness stigma? (United States)

    Corrigan, Patrick W


    Advocates and social marketers have used substantial resources to develop public service announcements (PSAs) as a lead strategy in public education and awareness campaigns meant to eliminate stigma associated with mental illness. Evaluations of PSAs are needed to determine whether this is a good investment. The author notes that very few studies have been reported in the peer-reviewed medical and psychological research literature addressing this question. Reports of government contractors suggest that PSAs have some effect as measured by population penetration, but such data provide no meaningful evidence about the impact of PSAs, such as real-world change in prejudicial attitudes and discriminatory behaviors. The author considers reasons for the limited impact of PSAs and proposes that social marketing campaigns could enhance their impact by targeting local groups.

  2. Evidence to support IL-13 as a risk locus for psoriatic arthritis but not psoriasis vulgaris.

    LENUS (Irish Health Repository)

    Bowes, John


    There is great interest in the identification of genetic factors that differentiate psoriatic arthritis (PsA) from psoriasis vulgaris (PsV), as such discoveries could lead to the identification of distinct underlying aetiological pathways. Recent studies identified single nucleotide polymorphisms (SNPs) in the interleukin 13 (IL-13) gene region as risk factors for PsV. Further investigations in one of these studies found the effect to be primarily restricted to PsA, thus suggesting the discovery of a specific genetic risk factor for PsA. Given this intriguing evidence, association to this gene was investigated in large collections of PsA and PsV patients and healthy controls.

  3. Skin tears: a review of the evidence to support prevention and treatment. (United States)

    Ratliff, Catherine R; Fletcher, Kathleen R


    Physiological changes that occur as part of the aging process put the elderly at risk for developing skin tears. Lack of consistent care in the management of skin tears in the authors' community sparked a literature search to determine best evidence for the management of skin tears. Medline and Cochrane Library databases were searched for studies and systematic reviews on skin tear prevention and treatment. The literature suggested that the greatest number of skin tears occurs among the elderly (65 years and older). Factors reported to be associated with the occurrence of skin tears in addition to age include immobility and a history of skin tears. In the absence of systematic risk factor research, clinicians continue to report that all variables that may be associated with these wounds must be considered when assessing the elderly. Several small studies suggest that most skin tears occur on the extremities and seasonal incidence variations also have been reported. Despite consistent sample-size limitations, the results of controlled clinical studies and case series consistently suggest that education and implementation of prevention protocols reduce the incidence of skin tears in extended care facilities by almost 50%. Studies to evaluate and compare the effectiveness and cost-effectiveness of skin tear treatments are limited but when appropriate care is provided most skin tears can be expected to heal after 7 to 21 days depending on the severity of the wound. A combination of skin protection, preventive measures, and treatments that facilitate moist wound healing appear to be most effective. Risk factor and epidemiological studies as well as research to validate the existing skin tear classification system and improve clinician ability to provide evidence-based risk assessments, preventive care, and treatment are needed.

    The El Niño/Southern Oscillation (ENSO) system during the Pliocene warm period (PWP; 3-5 million years ago) may have existed in a permanent El Niño state with a sharply reduced zonal sea surface temperature (SST) gradient in the equatorial Pacific Ocean. This suggests that during the PWP, when global mean temperatures and atmospheric carbon dioxide concentrations were similar to those projected for near-term climate change, ENSO variability--and related global climate teleconnections-could have been radically different from that today. Yet, owing to a lack of observational evidence on seasonal and interannual SST variability from crucial low-latitude sites, this fundamental climate characteristic of the PWP remains controversial. Here we show that permanent El Niño conditions did not exist during the PWP. Our spectral analysis of the δ(18)O SST and salinity proxy, extracted from two 35-year, monthly resolved PWP Porites corals in the Philippines, reveals variability that is similar to present ENSO variation. Although our fossil corals cannot be directly compared with modern ENSO records, two lines of evidence suggest that Philippine corals are appropriate ENSO proxies. First, δ(18)O anomalies from a nearby live Porites coral are correlated with modern records of ENSO variability. Second, negative-δ(18)O events in the fossil corals closely resemble the decreases in δ(18)O seen in the live coral during El Niño events. Prior research advocating a permanent El Niño state may have been limited by the coarse resolution of many SST proxies, whereas our coral-based analysis identifies climate variability at the temporal scale required to resolve ENSO structure firmly.

  5. What is the evidence to support the use of therapeutic gardens for the elderly? (United States)

    Detweiler, Mark B; Sharma, Taral; Detweiler, Jonna G; Murphy, Pamela F; Lane, Sandra; Carman, Jack; Chudhary, Amara S; Halling, Mary H; Kim, Kye Y


    Horticulture therapy employs plants and gardening activities in therapeutic and rehabilitation activities and could be utilized to improve the quality of life of the worldwide aging population, possibly reducing costs for long-term, assisted living and dementia unit residents. Preliminary studies have reported the benefits of horticultural therapy and garden settings in reduction of pain, improvement in attention, lessening of stress, modulation of agitation, lowering of as needed medications, antipsychotics and reduction of falls. This is especially relevant for both the United States and the Republic of Korea since aging is occurring at an unprecedented rate, with Korea experiencing some of the world's greatest increases in elderly populations. In support of the role of nature as a therapeutic modality in geriatrics, most of the existing studies of garden settings have utilized views of nature or indoor plants with sparse studies employing therapeutic gardens and rehabilitation greenhouses. With few controlled clinical trials demonstrating the positive or negative effects of the use of garden settings for the rehabilitation of the aging populations, a more vigorous quantitative analysis of the benefits is long overdue. This literature review presents the data supporting future studies of the effects of natural settings for the long term care and rehabilitation of the elderly having the medical and mental health problems frequently occurring with aging.

  6. What is the Best Strategy to Obtain Legislative Support? Survey Evidence from Brazilian State Assemblies

    Directory of Open Access Journals (Sweden)

    Felipe Nunes


    Full Text Available The legislative success of governments in Latin America has been explained by two main theories. For some authors, the main explanation involves the proactive and reactive powers of the chief executive. Other scholars argue that negotiations with deputies for portfolios and pork are the most important factors behind success in approving legislation. This paper proposes an innovative methodological strategy to test the mechanisms behind each of these theories. Original survey data of 12 Brazilian state-level assemblies is examined to assess elites' attitudes in regard to governors' strategies to obtain legislative support. Results suggest that there is not a unique equilibrium to the problem of coalition formation in multiparty settings. Deputies with concentrated constituencies, from more decentralized parties, and from conservative parties, tend to believe that the most efficient way a governor can obtain legislative support is to negotiate amendments with deputies. On the other hand, the more scattered a legislator's constituency and the more liberal or centralized his or her party, the more likely a deputy is to think that governors achieve better legislative success when they negotiate cabinet positions.

  7. "On the other hand ...": the evidence does not support the use of hand-carried ultrasound by hospitalists. (United States)

    Feldman, Mitchell D; Petersen, Amy Jean; Tice, Jeffrey A


    In the right hands, ultrasound is a safe and helpful diagnostic imaging tool. However, evidence supporting the use of hand-carried ultrasound (HCU) by hospitalist physicians has not kept pace with expanding application of these devices. In spite of its strategic point-of-care benefit, use of this technology by hospitalists may not ultimately translate into improved efficiency and better clinical outcomes. Optimal levels of training in image acquisition and interpretation remain to be established. Novelty, availability, and the results of a few small studies lacking patient-centered outcomes remain insufficient grounds to justify the expanded clinical utilization of these medical imaging devices by nonspecialists.

    The usage of decision support tools in emergency departments, based on predictive models, capable of estimating the probability of admission for patients in the emergency department may give nursing staff the possibility of allocating resources in advance. We present a methodology for developing and building one such system for a large specialized care hospital using a logistic regression and an artificial neural network model using nine routinely collected variables available right at the end of the triage process.A database of 255.668 triaged nonobstetric emergency department presentations from the Ramon y Cajal University Hospital of Madrid, from January 2011 to December 2012, was used to develop and test the models, with 66% of the data used for derivation and 34% for validation, with an ordered nonrandom partition. On the validation dataset areas under the receiver operating characteristic curve were 0.8568 (95% confidence interval, 0.8508-0.8583) for the logistic regression model and 0.8575 (95% confidence interval, 0.8540-0. 8610) for the artificial neural network model. χ Values for Hosmer-Lemeshow fixed "deciles of risk" were 65.32 for the logistic regression model and 17.28 for the artificial neural network model. A nomogram was generated upon the logistic regression model and an automated software decision support system with a Web interface was built based on the artificial neural network model.

  9. Pharmacokinetics of repeated sodium salicylate administration to laying hens: evidence for time dependent increase in drug elimination from plasma and eggs.

    Błażej Poźniak

    Full Text Available Salicylates were the first non-steroid anti-inflammatory drugs (NSAIDs to be used in any species and are still widely used in humans and livestock. However, the data on their pharmacokinetics in animals is limited, especially after repeated administration. Evidence exist that in chickens (Gallus gallus salicylate (SA may induce its own elimination. The aim of this study was to investigate salicylate pharmacokinetics and egg residues during repeated administration of sodium salicylate (SS to laying hens. Pharmacokinetics of SA was assessed during 14 d oral administration of SS at daily doses of 50 mg/kg and 200 mg/kg body weight to laying hens. On the 1st, 7th and 14th d a 24 h-long pharmacokinetic study was carried out, whereas eggs were collected daily. Salicylate concentrations in plasma and eggs were determined using high-performance liquid chromatography with ultraviolet detection and pharmacokinetic variables were calculated using a non-compartmental model. Mean residence time (MRT, minimal plasma concentration (Cmin, C16h and elimination half-life (T1/2el of SA showed gradual decrease in layers administered with a lower dose. Total body clearance (ClB increased. Layers administered with the higher dose showed a decrease only in the T1/2el. In the low dose group, SA was found only in the egg white and was low throughout the experiment. Egg whites from the higher dose group showed initially high SA levels which significantly decreased during the experiment. Yolk SA levels were lower and showed longer periods of accumulation and elimination. Repeated administration of SS induces SA elimination, although this effect may differ depending on the dose and production type of a chicken. Decreased plasma drug concentration may have clinical implications during prolonged SS treatment.

  10. Blobs versus bars: psychophysical evidence supports two types of orientation response in human color vision. (United States)

    Gheiratmand, Mina; Meese, Tim S; Mullen, Kathy T


    The classic hypothesis of Livingstone and Hubel (1984, 1987) proposed two types of color pathways in primate visual cortex based on recordings from single cells: a segregated, modular pathway that signals color but provides little information about shape or form and a second pathway that signals color differences and so defines forms without the need to specify their colors. A major problem has been to reconcile this neurophysiological hypothesis with the behavioral data. A wealth of psychophysical studies has demonstrated that color vision has orientation-tuned responses and little impairment on form related tasks, but these have not revealed any direct evidence for nonoriented mechanisms. Here we use a psychophysical method of subthreshold summation across orthogonal orientations for isoluminant red-green gratings in monocular and dichoptic viewing conditions to differentiate between nonoriented and orientation-tuned responses to color contrast. We reveal nonoriented color responses at low spatial frequencies (0.25-0.375 c/deg) under monocular conditions changing to orientation-tuned responses at higher spatial frequencies (1.5 c/deg) and under binocular conditions. We suggest that two distinct pathways coexist in color vision at the behavioral level, revealed at different spatial scales: one is isotropic, monocular, and best equipped for the representation of surface color, and the other is orientation-tuned, binocular, and selective for shape and form. This advances our understanding of the organization of the neural pathways involved in human color vision and provides a strong link between neurophysiological and behavioral data.

  12. Examining mutual suppression effects in the assessment of perfectionism cognitions: evidence supporting multidimensional assessment. (United States)

    Stoeber, Joachim; Kobori, Osamu; Brown, Anna


    Perfectionism cognitions capture automatic perfectionistic thoughts and have explained variance in psychological adjustment and maladjustment beyond trait perfectionism. The aim of the present research was to investigate whether a multidimensional assessment of perfectionism cognitions has advantages over a unidimensional assessment. To this aim, we examined in a sample of 324 university students how the Perfectionism Cognitions Inventory (PCI) and the Multidimensional Perfectionism Cognitions Inventory (MPCI) explained variance in positive affect, negative affect, and depressive symptoms when factor or subscale scores were used as predictors compared to total scores. Results showed that a multidimensional assessment (PCI factor scores, MPCI subscale scores) explained more variance than a unidimensional assessment (PCI and MPCI total scores) because, when the different dimensions were entered simultaneously as predictors, perfectionistic strivings cognitions and perfectionistic concerns cognitions acted as mutual suppressors thereby increasing each others' predictive validity. With this, the present findings provide evidence that--regardless of whether the PCI or the MPCI is used--a multidimensional assessment of perfectionism cognitions has advantages over a unidimensional assessment in explaining variance in psychological adjustment and maladjustment.

  13. Knowledge Brokering: An Innovative Model for Supporting Evidence-Informed Practice in Respiratory Care

    Directory of Open Access Journals (Sweden)

    Alison M Hoens


    Full Text Available The process of adopting research findings in the clinical setting is challenging, regardless of the area of practice. One strategy to facilitate this process is the use of knowledge brokering. Knowledge brokers (KBs are individuals who work to bridge the gap between researchers and knowledge users. In the health care setting, KBs work closely with clinicians to facilitate enhanced uptake of research findings into clinical practice. They also work with researchers to ensure research findings are translatable and meaningful to clinical practice. The present article discusses a KB’s role in a respiratory care setting. Working closely with both researchers and clinicians, the KB has led teams in the process of conceptualizing, developing, testing, disseminating and evaluating several projects related to respiratory care, including projects related to mobility in critical care settings and acute exacerbations of chronic obstructive pulmonary disease; inspiratory muscle training; and the use of incentive spirometry in postsurgical populations. The KB role has provided an important communication link between researcher and knowledge user that has facilitated evidence-informed practice to improve patient care.

  14. The California Health Policy Research Program - supporting policy making through evidence and responsive research. (United States)

    Roby, Dylan H; Jacobs, Ken; Kertzner, Alex E; Kominski, Gerald F


    This article explores the creation, design, and execution of a university-based collaboration to provide responsive research and evidence to a group of diverse health care, labor, and consumer stakeholders through convening a funded series of deliberative meetings, research briefs, peer-reviewed journal articles, ad hoc data analyses, and policy analyses. Funded by the California Endowment, the California Health Policy Research Program was created by researchers at the University of California, Berkeley Center for Labor Research and Education, and the UCLA Center for Health Policy Research. The collaboration not only allowed new research and analyses to be used by stakeholders and policy makers in decision making but also allowed university researchers to receive input on the important health policy issues of the day. The guidance of stakeholders in the research and policy analysis process was vital in driving meaningful results during an important time in health policy making in California. The manuscript discusses lessons learned in building relationships with stakeholders; meeting research and analytic needs; engaging stakeholders and policy makers; building capacity for quick-turnaround data collection and analysis, dissemination and publication; and maintaining the collaboration.

  15. Restoring State Control Over Forest Resources Through Administrative Procedures: Evidence From a Community Forestry Programme in Central Java, Indonesia

    Directory of Open Access Journals (Sweden)

    Ahmad Maryudi


    Full Text Available In recent years, community forestry has emerged as a means to reform power constellations with regard to forest governance. Through community forestry, the central state promised to devolve several forest rights to local communities and encouraged them to get involved in decision making processes and the implementation of forest activities. However, experience in some countries indicates that the implementation of community forestry programmes is rarely followed by genuine power devolution to local forest users. Instead, these programmes may even serve as a means to retain or restore the central state’s control over forests. Using a case study of a community forestry programme implemented in Java, Indonesia, by a state forest company, this paper argues that the implementation of community forestry is also driven by the state’s interests to regain control over the forests. Research in eight villages in Central Java province reveals that the community forestry programmes are carefully structured according to numerous administrative procedures and estab- lish a mode of control through a bureaucratic design. ----- In den letzten Jahren hat sich community forestry als Mittel zur Reform von Machtkonstellationen in Bezug auf die Verwaltung von Wäldern herausgebildet. Der Zentralstaat versprach durch community forestry bestimmte Waldrechte an lokale Communities abzugeben und ermutigte sie, sich an Entscheidungsprozessen und der Implementierung von Forstaktivitäten zu beteiligen. Erfahrungen in einigen Ländern zeigen jedoch, dass die Implementierung von community forestry-Programmen selten mit einem tatsächlichen Machttransfer an lokale ForstnutzerInnen einhergeht, sondern diese Programme sogar als Mittel zur Rückgewinnung von zentralstaatlicher Kontrolle über Wälder dienen können. Anhand eines Fallbeispiels eines community forestry-Programms, das in Java, Indonesien, von einem staatlichen Forstunternehmen implementiert wird, argumentiere ich

  16. Evidence to support IL-13 as a risk locus for psoriatic arthritis but not psoriasis vulgaris (United States)

    Bowes, John; Eyre, Steve; Flynn, Edward; Ho, Pauline; Salah, Salma; Warren, Richard B; Marzo-Ortega, Helena; Coates, Laura; McManus, Ross; Ryan, Anthony W; Kane, David; Korendowych, Eleanor; McHugh, Neil; FitzGerald, Oliver; Packham, Jonathan; Morgan, Ann W; Griffiths, Christopher E M; Bruce, Ian N; Worthington, Jane; Barton, Anne


    Objective There is great interest in the identification of genetic factors that differentiate psoriatic arthritis (PsA) from psoriasis vulgaris (PsV), as such discoveries could lead to the identification of distinct underlying aetiological pathways. Recent studies identified single nucleotide polymorphisms (SNPs) in the interleukin 13 (IL-13) gene region as risk factors for PsV. Further investigations in one of these studies found the effect to be primarily restricted to PsA, thus suggesting the discovery of a specific genetic risk factor for PsA. Given this intriguing evidence, association to this gene was investigated in large collections of PsA and PsV patients and healthy controls. Methods Two SNPs (rs20541 and rs1800925) mapping to the IL-13 gene were genotyped in 1057 PsA and 778 type I PsV patients using the Sequenom genotyping platform. Genotype frequencies were compared to those of 5575 healthy controls. Additional analyses were performed in phenotypic subgroups of PsA (type I or II PsV and in those seronegative for rheumatoid factor). Results Both SNPs were found to be highly associated with susceptibility to PsA (rs1800925 ptrend = 6.1×10−5 OR 1.33, rs20541 ptrend = 8.0×10−4 OR 1.27), but neither SNP was significantly associated with susceptibility to PsV. Conclusions This study confirms that the effect of IL-13 risk locus is specific for PsA, thus highlighting a key biological pathway that differentiates PsA from PsV. The identification of markers that differentiate the two diseases raises the possibility in future of allowing screening of PsV patients to identify those at risk of developing PsA. PMID:21349879

    In view of the geographically closest location to Andaman archipelago,Myanmar was suggested to be the origin place of aboriginal Andamanese.However,for lacking any genetic information from this region,which has prevented to resolve the dispute on whether the aboriginal Andamanese were originated from mainland India or Myanmar.To solve this question and better understand the origin of the aboriginal Andamanese,we screened for haplogroups M31(from which Andaman-specific lineage M31a1 branched off)and M32 among 846mitochondrial DNAs(mtDNAs)sampled across Myanmar.As a result,two Myanmar individuals belonging to haplogroup M31 were identified,and completely sequencing the entire mtDNA genomes of both samples testified that the two M31 individuals observed in Myanmar were probably attributed to the recent gene flow from northeast India populations.Since no root lineages of haplogroup M31 or M32 were observed in Myanmar,it is unlikely that Myanmar may serve as the source place of the aboriginal Andamanese.To get further insight into the origin of this unique population,the detailed phylogenetic and phylogeographic analyses were performed by including additional 7 new entire mtDNA genomes and 113 M31 mtDNAs pinpointed from South Asian populations,and the results suggested that Andaman-specific M31a1 could in fact trace its origin to northeast India.Time estimation results further indicated that the Andaman archipelago was likely settled by modern humans from northeast India via the land-bridge which connected the Andaman archipelago and Myanmar around the Last Glacial Maximum(LGM),a scenario in well agreement with the evidence from linguistic and palaeoclimate studies.

  18. Mobile DNA and the TE-Thrust hypothesis: supporting evidence from the primates

    Directory of Open Access Journals (Sweden)

    Oliver Keith R


    Full Text Available Abstract Transposable elements (TEs are increasingly being recognized as powerful facilitators of evolution. We propose the TE-Thrust hypothesis to encompass TE-facilitated processes by which genomes self-engineer coding, regulatory, karyotypic or other genetic changes. Although TEs are occasionally harmful to some individuals, genomic dynamism caused by TEs can be very beneficial to lineages. This can result in differential survival and differential fecundity of lineages. Lineages with an abundant and suitable repertoire of TEs have enhanced evolutionary potential and, if all else is equal, tend to be fecund, resulting in species-rich adaptive radiations, and/or they tend to undergo major evolutionary transitions. Many other mechanisms of genomic change are also important in evolution, and whether the evolutionary potential of TE-Thrust is realized is heavily dependent on environmental and ecological factors. The large contribution of TEs to evolutionary innovation is particularly well documented in the primate lineage. In this paper, we review numerous cases of beneficial TE-caused modifications to the genomes of higher primates, which strongly support our TE-Thrust hypothesis.

  20. Genetic Evidence Supports the Multiethnic Character of Teopancazco, a Neighborhood Center of Teotihuacan, Mexico (AD 200-600) (United States)

    Álvarez-Sandoval, Brenda A.; Manzanilla, Linda R.; González-Ruiz, Mercedes; Malgosa, Assumpció; Montiel, Rafael


    Multiethnicity in Teopancazco, Teotihuacan, is supported by foreign individuals found in the neighborhood center as well as by the diversity observed in funerary rituals at the site. Studies of both stable and strontium isotopes as well as paleodietary analysis, suggest that the population of Teopancazco was composed by three population groups: people from Teotihuacan, people from nearby sites (Tlaxcala-Hidalgo-Puebla), and people from afar, including the coastal plains. In an attempt to understand the genetic dynamics in Teopancazco we conducted an ancient DNA (aDNA) analysis based on mtDNA. Our results show that the level of genetic diversity is consistent with the multiethnicity phenomenon at the neighborhood center. Levels of genetic diversity at different time periods of Teopancazco’s history show that multiethnicity was evident since the beginning and lasted until the collapse of the neighborhood center. However, a PCA and a Neighbor-Joining tree suggested the presence of a genetically differentiated group (buried at the Transitional phase) compared to the population from the initial phase (Tlamimilolpa) as well as the population from the final phase (Xolalpan) of the history of Teopancazco. Genetic studies showed no differences in genetic diversity between males and females in the adult population of Teopancazco, this data along with ample archaeological evidence, suggest a neolocal post-marital pattern of residence in Teopancazco. Nevertheless, genetic analyses on the infant population showed that the males are significantly more heterogeneous than the females suggesting a possible differential role in cultural practices by sex in the infant sector. Regarding interpopulation analysis, we found similar indices of genetic diversity between Teopancazco and heterogeneous native groups, which support the multiethnic character of Teopancazco.

  5. Plant-based medicines for anxiety disorders, part 2: a review of clinical studies with supporting preclinical evidence. (United States)

    Sarris, Jerome; McIntyre, Erica; Camfield, David A


    Research in the area of herbal psychopharmacology has revealed a variety of promising medicines that may provide benefit in the treatment of general anxiety and specific anxiety disorders. However, a comprehensive review of plant-based anxiolytics has been absent to date. Thus, our aim was to provide a comprehensive narrative review of plant-based medicines that have clinical and/or preclinical evidence of anxiolytic activity. We present the article in two parts. In part one, we reviewed herbal medicines for which only preclinical investigations for anxiolytic activity have been performed. In this current article (part two), we review herbal medicines for which there have been both preclinical and clinical investigations of anxiolytic activity. A search of MEDLINE (PubMed), CINAHL, Scopus and the Cochrane Library databases was conducted (up to 28 October 2012) for English language papers using the search terms 'anxiety' OR 'anxiety disorder' OR 'generalized anxiety disorder' OR 'social phobia' OR 'post-traumatic stress disorder' OR 'panic disorder' OR 'agoraphobia' OR 'obsessive compulsive disorder' in combination with the search terms 'Herb*' OR 'Medicinal Plants' OR 'Botanical Medicine' OR 'Chinese herb*', in addition to individual herbal medicines. This search of the literature revealed 1,525 papers, of which 53 plants were included in the review (having at least one study using the whole plant extract). Of these plants, 21 had human clinical trial evidence (reviewed here in part two), with the other 32 having solely preclinical evidence (reviewed in part one). Support for efficacy was found for chronic use (i.e. greater than one day) of the following herbs in treating a range of anxiety disorders in human clinical trials: Piper methysticum, Matricaria recutita, Ginkgo biloba, Scutellaria lateriflora, Silybum marianum, Passiflora incarnata, Withania somniferum, Galphimia glauca, Centella asiatica, Rhodiola rosea, Echinacea spp., Melissa officinalis and Echium

  7. Ethnography, fidelity, and the evidence that anthropology adds: supplementing the fidelity process in a clinical trial of supported employment. (United States)

    Smith-Morris, Carolyn; Lopez, Gilberto; Ottomanelli, Lisa; Goetz, Lance; Dixon-Lawson, Kimberly


    This discussion considers the role and findings of ethnographic research within a clinical trial of supported employment for veterans with spinal cord injury. Contributing to qualitative evaluation research and to debates over anthropological evidence vis-à-vis clinical trials, we demonstrate how enactors of a randomized controlled trial can simultaneously attend to both the trial's evidentiary and procedural requirements and to the lived experiences and needs of patients and clinicians. Three major findings are described: (1) contextual information essential to fidelity efforts within the trial; (2) the role of human interrelationships and idiosyncratic networks in the trial's success; and (3) a mapping of the power and authority structures relevant to the staff's ability to perform the protocol. We emphasize strengths of anthropological ethnography in clinical trials that include the provision of complementary, qualitative data, the capture of otherwise unmeasured parts of the trial, and the realization of important information for the translation of the clinical findings into new settings.

  8. SINFONI/VLT 3D spectroscopy of massive galaxies: evidence of rotational support at z ˜ 1.4 (United States)

    Buitrago, Fernando; Conselice, Christopher J.; Epinat, Benoît; Bedregal, Alejandro G.; Grützbauch, Ruth; Weiner, Benjamin J.


    There is cumulative evidence showing that, for the most massive galaxies, the fraction of disc-like objects compared to those with spheroidal properties increases with redshift. However, this evolution is thus far based on the surface brightness study of these objects. To explore the consistency of this scenario, it is necessary to measure the dynamical status of these galaxies. With this aim, we have obtained seeing-limited near-infrared integral-field spectra in the H-band for 10 massive galaxies (M_{*}≥ 10^{11} h_{70}^{-2} M_{⊙}) at z ˜ 1.4 with SINFONI at the VLT. Our sample is selected by their stellar mass and EW[O II] > 15 Å, to secure their kinematic measurements, but without accounting for any morphological or flux criteria a priori. Through this 3D kinematic spectroscopy analysis, we find that half (i.e. 50 ± 7 per cent) of our galaxies are compatible with being rotationally supported discs, in agreement with previous morphological expectations. This is a factor of approximately 2 higher than what is observed in the present Universe for objects of the same stellar mass. Strikingly, the majority of our sample of massive galaxies show extended and fairly high rotational velocity maps, implying that massive galaxies acquire rapidly rotational support and hence gravitational equilibrium. Our sample also show evidence for ongoing interactions and mergers. Summarizing, massive galaxies at high-z show a significant diversity and must have continued evolution beyond the fading of stellar populations, to become their present-day counterparts.

  9. Evidence Supporting the Uptake and Genomic Incorporation of Environmental DNA in the “Ancient Asexual” Bdelloid Rotifer Philodina roseola

    Directory of Open Access Journals (Sweden)

    Olaf R. P. Bininda-Emonds


    Full Text Available Increasing evidence suggests that bdelloid rotifers regularly undergo horizontal gene transfer, apparently as a surrogate mechanism of genetic exchange in the absence of true sexual reproduction, in part because of their ability to withstand desiccation. We provide empirical support for this latter hypothesis using the bdelloid Philodina roseola, which we demonstrate to readily internalize environmental DNA in contrast to a representative monogonont rotifer (Brachionus rubens, which, like other monogononts, is facultative sexual and cannot withstand desiccation. In addition, environmental DNA that was more similar to the host DNA was retained more often and for a longer period of time. Indirect evidence (increased variance in the reproductive output of the untreated F1 generation suggests that environmental DNA can be incorporated into the genome during desiccation and is thus heritable. Our observed fitness effects agree with sexual theory and also occurred when the animals were desiccated in groups (thereby acting as DNA donors, but not individually, indicating the mechanism could occur in nature. Thus, although DNA uptake and its genomic incorporation appears proximally related to anhydrobiosis in bdelloids, it might also facilitate accidental genetic exchange with closely related taxa, thereby maintaining higher levels of genetic diversity than is otherwise expected for this group of “ancient asexuals”.

  10. Supporting Better Evidence Generation and Use within Social Innovation in Health in Low- and Middle-Income Countries: A Qualitative Study (United States)

    Tran, Jenny; Hersch, Fred; Lockwood, Amy; Montgomery, Paul


    Background While several papers have highlighted a lack of evidence to scale social innovations in health, fewer have explored decision-maker understandings of the relative merit of different types of evidence, how such data are interpreted and applied, and what practical support is required to improve evidence generation. The objectives of this paper are to understand (1) beliefs and attitudes towards the value of and types of evidence in scaling social innovations for health, (2) approaches to evidence generation and evaluation used in systems and policy change, and (3) how better evidence-generation can be undertaken and supported within social innovation in health. Methods Thirty-two one-on-one interviews were conducted between July and November 2015 with purposively selected practitioners, policymakers, and funders from low- and middle- income countries (LMICs). Data were analysed using a Framework Analysis Approach. Results While practitioners, funders, and policymakers said they held outcome evidence in high regard, their practices only bear out this assertion to varying degrees. Few have given systematic consideration to potential unintended consequences, in particular harm, of the programs they implement, fund, or adopt. Stakeholders suggest that better evidence-generation can be undertaken and supported within social innovation in health by supporting the research efforts of emerging community organizations; creating links between practitioners and academia; altering the funding landscape for evidence-generation; providing responsive technical education; and creating accountability for funders, practitioners, and policymakers. Conclusion How better evidence-generation can be undertaken and supported within social innovation in health is a previously under-operationalised aspect of the policy-making process that remains essential in order to refrain from causing harm, enable the optimization of existing interventions, and ultimately, to scale and fund what

  11. Numerical morphology supports early number word learning: Evidence from a comparison of young Mandarin and English learners. (United States)

    Le Corre, Mathieu; Li, Peggy; Huang, Becky H; Jia, Gisela; Carey, Susan


    Previous studies showed that children learning a language with an obligatory singular/plural distinction (Russian and English) learn the meaning of the number word for one earlier than children learning Japanese, a language without obligatory number morphology (Barner, Libenson, Cheung, & Takasaki, 2009; Sarnecka, Kamenskaya, Yamana, Ogura, & Yudovina, 2007). This can be explained by differences in number morphology, but it can also be explained by many other differences between the languages and the environments of the children who were compared. The present study tests the hypothesis that the morphological singular/plural distinction supports the early acquisition of the meaning of the number word for one by comparing young English learners to age and SES matched young Mandarin Chinese learners. Mandarin does not have obligatory number morphology but is more similar to English than Japanese in many crucial respects. Corpus analyses show that, compared to English learners, Mandarin learners hear number words more frequently, are more likely to hear number words followed by a noun, and are more likely to hear number words in contexts where they denote a cardinal value. Two tasks show that, despite these advantages, Mandarin learners learn the meaning of the number word for one three to six months later than do English learners. These results provide the strongest evidence to date that prior knowledge of the numerical meaning of the distinction between singular and plural supports the acquisition of the meaning of the number word for one.

  12. On Criminal Judicialization of the Administrative Evidence%行政证据刑事司法化--兼论《刑事诉讼法》第52条的理解与适用

    Institute of Scientific and Technical Information of China (English)



    The 2012 criminal procedure law determines that the administrative evidence can be used as evidence in criminal lawsuit, negating the traditional evidence conversion in theory. The criminal judicialization of the administrative evidence arose. To the evidence conversion, the criminal judicialization of the administrative evidence is more consistent with the legislative intention, manifests the systematization of criminal law, respects and guarantees human rights and the value of lawsuit efficiency and plays a guiding role to improve the lawmaking. The effective connection of the administrative evidence and the criminal evidence cannot separate the judiciary and the justice, that’s to say, we must understand well the importance of the administrative evidence in the process of the criminal judicial procedure and its key role, build up ideas to respect and safeguard human rights.%2012《刑事诉讼法》对行政证据在刑事诉讼中作为证据使用予以认可,从理论维度对传统的证据转换说予以否定,行政证据刑事司法化应运而生。较证据转换说而言,行政证据刑事司法化更符合立法原意,体现刑事法律的体系化,遵循尊重和保障人权以及诉讼效率的价值,对立法完善起着导向作用。有效衔接行政证据与刑事证据,离不开司法人员合法、正当司法:明确行政证据在刑事司法程序中的重要性以及所扮演的关键角色,树立尊重和保障人权的理念。

  13. Do community pharmacists have the attitudes and knowledge to support evidence based self-management of low back pain?

    Directory of Open Access Journals (Sweden)

    Waddell Gordon


    Full Text Available Abstract Background In many countries, community pharmacists can be consulted without appointment in a large number of convenient locations. They are in an ideal position to give advice to patients at the onset of low back pain and also reinforce advice given by other healthcare professionals. There is little specific information about the quality of care provided in the pharmacy for people with back pain. The main objectives of this survey were to determine the attitudes, knowledge and reported practice of English pharmacists advising people who present with acute or chronic low back pain. Methods A questionnaire was designed for anonymous self-completion by pharmacists attending continuing education sessions. Demographic questions were designed to allow comparison with a national pharmacy workforce survey. Attitudes were measured with the Back Beliefs Questionnaire (BBQ and questions based on the Working Backs Scotland campaign. Questions about the treatment of back pain in the community pharmacy were written (or adapted to reflect and characterise the nature of practice. In response to two clinical vignettes, respondents were asked to select proposals that they would recommend in practice. Results 335 responses from community pharmacists were analysed. Middle aged pharmacists, women, pharmacy managers and locums were over-represented compared to registration and workforce data. The mean (SD BBQ score for the pharmacists was 31.37 (5.75, which was slightly more positive than in similar surveys of other groups. Those who had suffered from back pain seem to demonstrate more confidence (fewer negative feelings, more advice opportunities and better advice provision in their perception of advice given in the pharmacy. Awareness of written information that could help to support practice was low. Reponses to the clinical vignettes were generally in line with the evidence base. Pharmacists expressed some caution about recommending activity. Most

  15. Can scientific evidence support using Bangladeshi traditional medicinal plants in the treatment of diarrhoea? A review on seven plants. (United States)

    Wangensteen, Helle; Klarpås, Line; Alamgir, Mahiuddin; Samuelsen, Anne B C; Malterud, Karl E


    Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking water and an increased risk of spreading the water-borne disease. Not surprisingly, plants found in the near surroundings have been taken into use by the local community as medicine to treat diarrhoeal symptoms. These plants are cheaper and more easily available than conventional medicine. Our question is: What is the level of documentation supporting the use of these plants against diarrhoea and is their consumption safe? Do any of these plants have potential for further exploration? In this review, we have choosen seven plant species that are used in the treatment of diarrhoea; Diospyros peregrina, Heritiera littoralis, Ixora coccinea, Pongamia pinnata, Rhizophora mucronata, Xylocarpus granatum, and Xylocarpus moluccensis. Appearance and geographical distribution, traditional uses, chemical composition, and biological studies related to antidiarrhoeal activity will be presented. This review reveals that there is limited scientific evidence supporting the traditional use of these plants. Most promising are the barks from D. peregrina, X. granatum and X. moluccensis which contain tannins and have shown promising results in antidiarrhoeal mice models. The leaves of P. pinnata also show potential. We suggest these plants should be exploited further as possible traditional herbal remedies against diarrhoea including studies on efficacy, optimal dosage and safety.

    Full Text Available Objective – To examine the extent to which six commercial database products support student and faculty research in the area of public administration. Design – Bibliometric study. Setting – Academic library in the United States. Subjects – Six commercial business‐related database products were examined: Proquest’s ABI/INFORM Global edition (ABI, EBSCO’s Business Source Premier (BSP, Gale’s General BusinessFile ASAP (GBF, EBSCO’s Academic Search Premier (ASP, EBSCO’s Expanded Academic Index (EAI and Proquest’s International Academic Research Library (ARL. Three of the databases (ABI, BSP, GBF were chosen because they address the management, human resource, and financing elements of public administration. The other three (ASP, EAI, ARL were included because of their multidisciplinary coverage. Methods – A list of journal titles covering public administration was assembled from the Institute of Scientific Information’s Social Sciences Citation Index and previously published lists of recommended journals in the field. The author then compared the compiled list of journal titles against the journal titles indexed by the six database products. He further analyzed the results by level of journal coverage (abstract only, full‐text, and full‐text with embargo and subject area based on categories described in Ulrich’s Periodicals Directory. Main Results – The study found that three of the six database products ‐‐EAI, BSP, and ARL ‐‐ provide indexing for the greatest number of public administration journals contained in the compiled list. EIA and ARL cover the greatest number of those that are full‐text journals, while BSP and ASP cover the greatest number of those full‐text journals limited by publisher embargoes. Conclusion – The author concludes that of the six databases examined, EAI, BSP, and ARL are the best for public administration research, based on their strength in the subject areas of public

    The so-called zebra sole includes a group of small flatfishes characterized by transverse band pairs on the ocular side and distributed throughout shallow waters along the coast of the Indo-West Pacific Ocean. Sev-eral species of the zebra sole have been recorded from the coastal waters of China. Morphological analysis of 1 107 specimens of the zebra sole from 15 successive localities along the China’s coast demonstrated that no significant variations among these localities were found on the basis of meristic counts and morphometric characters. Phylogenetic analysis based onCOI gene sequences of 14 individuals and D-loop of 22 indi-viduals from eight localities showed that they were indistinguishable among these localities. Therefore, both morphological and molecular evidence supported the occurrence of a single species of the zebra sole along the China’s coast. The available name for this species isZebriaszebrinus (Temminck and Schlegel, 1846) in-stead ofZ.zebra (Bloch, 1787).Zebrias fasciatus(Basilewsky, 1855) andSolea ommatura (Richardson, 1846) are considered here as two synonyms ofZ. zebrinus.

  19. Evidence-Based Support for the Characteristics of Tsunami Warning Messages for Local, Regional and Distant Sources (United States)

    Gregg, C. E.; Johnston, D. M.; Sorensen, J. H.; Vogt Sorensen, B.; Whitmore, P.


    Many studies since 2004 have documented the dissemination and receipt of risk information for local to distant tsunamis and factors influencing people's responses. A few earlier tsunami studies and numerous studies of other hazards provide additional support for developing effective tsunami messages. This study explores evidence-based approaches to developing such messages for the Pacific and National Tsunami Warning Centers in the US. It extends a message metric developed for the NWS Tsunami Program. People at risk to tsunamis receive information from multiple sources through multiple channels. Sources are official and informal and environmental and social cues. Traditionally, official tsunami messages followed a linear dissemination path through relatively few channels from warning center to emergency management to public and media. However, the digital age has brought about a fundamental change in the dissemination and receipt of official and informal communications. Information is now disseminated in very non-linear paths and all end-user groups may receive the same message simultaneously. Research has demonstrated a range of factors that influence rapid respond to an initial real or perceived threat. Immediate response is less common than one involving delayed protective actions where people first engage in "milling behavior" to exchange information and confirm the warning before taking protective action. The most important message factors to achieve rapid response focus on the content and style of the message and the frequency of dissemination. Previously we developed a tsunami message metric consisting of 21 factors divided into message content and style and receiver characteristics. Initially, each factor was equally weighted to identify gaps, but here we extend the work by weighting specific factors. This utilizes recent research that identifies the most important determinants of protective action. We then discuss the prioritization of message information

  20. Cerebrospinal fluid metabolomics identifies a key role of isocitrate dehydrogenase in bipolar disorder: evidence in support of mitochondrial dysfunction hypothesis (United States)

    Yoshimi, N; Futamura, T; Bergen, S E; Iwayama, Y; Ishima, T; Sellgren, C; Ekman, C J; Jakobsson, J; Pålsson, E; Kakumoto, K; Ohgi, Y; Yoshikawa, T; Landén, M; Hashimoto, K


    Although evidence for mitochondrial dysfunction in the pathogenesis of bipolar disorder (BD) has been reported, the precise biological basis remains unknown, hampering the search for novel biomarkers. In this study, we performed metabolomics of cerebrospinal fluid (CSF) from male BD patients (n=54) and age-matched male healthy controls (n=40). Subsequently, post-mortem brain analyses, genetic analyses, metabolomics of CSF samples from rats treated with lithium or valproic acid were also performed. After multivariate logistic regression, isocitric acid (isocitrate) levels were significantly higher in the CSF from BD patients than healthy controls. Furthermore, gene expression of two subtypes (IDH3A and IDH3B) of isocitrate dehydrogenase (IDH) in the dorsolateral prefrontal cortex from BD patients was significantly lower than that of controls, although the expression of other genes including, aconitase (ACO1, ACO2), IDH1, IDH2 and IDH3G, were not altered. Moreover, protein expression of IDH3A in the cerebellum from BD patients was higher than that of controls. Genetic analyses showed that IDH genes (IDH1, IDH2, IDH3A, IDH3B) and ACO genes (ACO1, ACO2) were not associated with BD. Chronic (4 weeks) treatment with lithium or valproic acid in rats did not alter CSF levels of isocitrate, and mRNA levels of Idh3a, Idh3b, Aco1 and Aco2 genes in the rat brain. These findings suggest that abnormality in the metabolism of isocitrate by IDH3A in the mitochondria plays a key role in the pathogenesis of BD, supporting the mitochondrial dysfunction hypothesis of BD. Therefore, IDH3 in the citric acid cycle could potentially be a novel therapeutic target for BD. PMID:26782057

    In order to achieve success in today's competitive world, organizations should adapt to environmental changes. On the other hand, managers should have a set of values and ethical guidelines for their administrative and organizational functions. This study aimed to investigate the association between work ethics and attitudes towards organizational changes among the administrative, financial and support employees of general teaching hospitals affiliated to Shiraz University of Medical Sciences. This was an applied, cross-sectional and descriptive-analytic study conducted in 2013. A sample of 124 employees was selected using stratified sampling proportional to size and simple random sampling methods. Data were collected using 2 questionnaires measuring the dimensions of employees' work ethics (four dimensions) and attitudes towards organizational changes (three dimensions). The collected data were analyzed using SPSS 18.0 and statistical tests, including ANOVA, independent samples t-test, and Pearson's correlation coefficient. A P ethic dimensions were related to being cooperative (4.60 ± 0.38) and dependable (4.29 ± 0.39) respectively. On the other hand, the maximum and minimum score of attitudes towards the various dimensions of organizational changes were related to the behavioral (3.83 ± 0.70) and the affective (3.55 ± 0.88) dimensions respectively. Furthermore, there was a significant relationship between the work ethics and education levels of the employees in this study (P = 0.003). Also, among work s dimensions, only being considerate had a significant association with attitudes towards organizational changes (P = 0.014) and their cognitive dimension (P = 0.005). To improve employees' work ethics and attitudes towards organizational changes, the following suggestions can be offered: training hospitals managers in participative management style and its application, as well as the importance of meeting the employees' needs and expectations based on their

  2. Intracerebroventricular Administration of Streptozotocin as an Experimental Approach to Depression: Evidence for the Involvement of Proinflammatory Cytokines and Indoleamine-2,3-Dioxygenase. (United States)

    Souza, Leandro Cattelan; Jesse, Cristiano R; de Gomes, Marcelo Gomes; Viana, Cristini Escobar; Mattos, Etiara; Silva, Neici Cáceres; Boeira, Silvana Peterini


    There is a lack of information about the molecular events underlying the depressive-like effect of an intracerebroventricular injection of streptozotocin (ICV-STZ) in mice. Elevated activity of the tryptophan-degrading enzyme indoleamine-2,3-dioxygenase (IDO) has been proposed to mediate depression in inflammatory disorders. In this study, we report that ICV-STZ activates IDO in the hippocampus of mice and culminates in depressive-like behaviors, measured by an increased duration in immobility time in the forced swimming test and decreased total time of grooming in the splash test. Indirect blockade of IDO activation with the cytokine inhibitor minocycline prevents the development of depressive-like behaviors and attenuates STZ-induced upregulation of proinflammatory cytokines in the hippocampus. Minocycline abrogates the increase in tryptophan and kynurenine levels as well as prevents serotonin dysfunction in the hippocampus of STZ-injected mice. These results suggest that hippocampal IDO activation in STZ-associated depressive-like behavior is mediated by proinflammatory cytokine-dependent mechanisms. Our study not only extends the evidence that IDO has a critical role in mediating inflammation-induced depression but also supports the notion that neuroinflammation and the kynurenine pathway are important targets of novel therapeutic drugs for depression. In addition, our study provides new insights into the neurobiological mechanisms underlying ICV-STZ and indicates that this model could be employed in the preclinical research of depression.

  3. Pilot study on developing a decision support tool for guiding re-administration of chemotherapeutic agent after a serious adverse drug reaction

    Directory of Open Access Journals (Sweden)

    Chew Lita


    Full Text Available Abstract Background Currently, there are no standard guidelines for recommending re-administration of a chemotherapeutic drug to a patient after a serious adverse drug reaction (ADR incident. The decision on whether to rechallenge the patient is based on the experience of the clinician and is highly subjective. Thus the aim of this study is to develop a decision support tool to assist clinicians in this decision making process. Methods The inclusion criteria for patients in this study are: (1 had chemotherapy at National Cancer Centre Singapore between 2004 to 2009, (2 suffered from serious ADRs, and (3 were rechallenged. A total of 46 patients fulfilled the inclusion criteria. A genetic algorithm attribute selection method was used to identify clinical predictors for patients' rechallenge status. A Naïve Bayes model was then developed using 35 patients and externally validated using 11 patients. Results Eight patient attributes (age, chemotherapeutic drug, albumin level, red blood cell level, platelet level, abnormal white blood cell level, abnormal alkaline phosphatase level and abnormal alanine aminotransferase level were identified as clinical predictors for rechallenge status of patients. The Naïve Bayes model had an AUC of 0.767 and was found to be useful for assisting clinical decision making after clinicians had identified a group of patients for rechallenge. A platform independent version and an online version of the model is available to facilitate independent validation of the model. Conclusion Due to the limited size of the validation set, a more extensive validation of the model is necessary before it can be adopted for routine clinical use. Once validated, the model can be used to assist clinicians in deciding whether to rechallenge patients by determining if their initial assessment of rechallenge status of patients is accurate.

  4. Using a training-of-trainers approach and proactive technical assistance to bring evidence based programs to scale: an operationalization of the interactive systems framework's support system. (United States)

    Ray, Marilyn L; Wilson, Mary Martha; Wandersman, Abraham; Meyers, Duncan C; Katz, Jason


    Bringing evidence based programs to scale was a major initial impetus for the development of the Interactive Systems Framework for Dissemination and Implementation (ISF). The ISF demonstrates the importance of the Support System in facilitating the uptake of innovations in the community (the Delivery System). Two strategies that members of the Support System commonly use are training-of-trainers (TOT) models and technical assistance (TA). In this article, we focus on the role of the Support System in bringing evidence-based programs (EBPs) to scale in the Delivery System using a case example, with special attention on two strategies employed by Support Systems-training-of-trainers (TOT) and proactive technical assistance. We then report on findings from a case example from the Promoting Science Based Approaches to Teen Pregnancy Prevention project that furthers our conceptualization of these strategies and the evidence base for them. We also report on the limitations in the literature regarding research on TOTs and proactive TA and provide suggestions for future research on TOTs and proactive TA that will enhance the science and practice of support in the ISF.

  9. Working group reports: evaluation of the evidence to support practice guidelines for nutritional care of preterm infants-the Pre-B Project. (United States)

    Raiten, Daniel J; Steiber, Alison L; Carlson, Susan E; Griffin, Ian; Anderson, Diane; Hay, William W; Robins, Sandra; Neu, Josef; Georgieff, Michael K; Groh-Wargo, Sharon; Fenton, Tanis R


    The "Evaluation of the Evidence to Support Practice Guidelines for the Nutritional Care of Preterm Infants: The Pre-B Project" is the first phase in a process to present the current state of knowledge and to support the development of evidence-informed guidance for the nutritional care of preterm and high-risk newborn infants. The future systematic reviews that will ultimately provide the underpinning for guideline development will be conducted by the Academy of Nutrition and Dietetics' Evidence Analysis Library (EAL). To accomplish the objectives of this first phase, the Pre-B Project organizers established 4 working groups (WGs) to address the following themes: 1) nutrient specifications for preterm infants, 2) clinical and practical issues in enteral feeding of preterm infants, 3) gastrointestinal and surgical issues, and 4) current standards of infant feeding. Each WG was asked to 1) develop a series of topics relevant to their respective themes, 2) identify questions for which there is sufficient evidence to support a systematic review process conducted by the EAL, and 3) develop a research agenda to address priority gaps in our understanding of the role of nutrition in health and development of preterm/neonatal intensive care unit infants. This article is a summary of the reports from the 4 Pre-B WGs.

  10. Informal support networks of low-income senior women living alone: evidence from Fort St. John, BC. (United States)

    Ryser, Laura; Halseth, Greg


    Within the context of an aging Canadian rural and small-town landscape, there is a growing trend of low-income senior women living alone. While there is a perception that rural seniors have well-developed social networks to meet their daily needs, some research suggests that economic and social restructuring processes have impacted the stability of seniors' support networks in small places. While much of the research on seniors' informal networks focuses upon small towns in decline, booming resource economies can also produce challenges for low-income senior women living alone due to both a higher cost of living and the retrenchment of government and service supports. Under such circumstances, an absence of informal supports can impact seniors' health and quality of life and may lead to premature institutionalization. Drawing upon a household survey in Fort St. John, British Columbia, we explore informal supports used by low-income senior women living alone in this different context of the Canadian landscape. Our findings indicate that these women not only have a support network that is comparable to other groups, but that they are also more likely to draw upon such supports to meet their independent-living needs. These women rely heavily on family support, however, and greater efforts are needed to diversify both their formal and informal sources of support as small family networks can quickly become overwhelmed.

    Complex regulatory decisions about risk rely on the brokering of evidence between providers and recipients, and involve personality and power relationships that influence the confidence that recipients may place in the sufficiency of evidence and, therefore, the decision outcome. We explore these relationships in an agent-based model; drawing on concepts from environmental risk science, decision psychology and computer simulation. A two-agent model that accounts for the sufficiency of evidence is applied to decisions about salt intake, animal carcass disposal and radioactive waste. A dynamic version of the model assigned personality traits to agents, to explore their receptivity to evidence. Agents with ‘aggressor’ personality sets were most able to imbue fellow agents with enhanced receptivity (with ‘avoider’ personality sets less so) and clear confidence in the sufficiency of evidence. In a dynamic version of the model, when both recipient and provider were assigned the ‘aggressor’ personality set, this resulted in 10 successful evidence submissions in 71 days, compared with 96 days when both agents were assigned the ‘avoider’ personality set. These insights suggest implications for improving the efficiency and quality of regulatory decision making by understanding the role of personality and power. - Highlights: •The role of personality and power in regulatory decision-making is poorly represented. •We built a rudimentary two-agent model to explore environmental risk decisions. •Our two agent model accounted for decisions about the sufficiency of evidence. •We examined the influence personality and power has on confidence gained. •By giving agents personality we might predict the time taken to reach consensus.

  14. Assessing the need for an online decision-support tool to promote evidence-based practices of psychosocial counseling in HIV care. (United States)

    Kukafka, Rita; Millery, Mari; Chan, Connie; LaRock, William; Bakken, Suzanne


    Psychosocial counselors have a vital and challenging role in supporting persons living with HIV/AIDS (PLWH/A) to better manage their disease. However, gaps in training, education, and skills limit the effectiveness of counselors' efforts. We propose that the use of a decision-support tool for counselors at the point of care can support them in their work as well as help alleviate many training and practice gaps. Decision-support tools aimed at reducing knowledge and practice gaps are used extensively to assist clinical providers at the point of care; however, there is a need for decision-support tools designed specifically for HIV/AIDS counselors. To identify requirements for such a tool, we conducted a needs assessment through interviews of 19 HIV/AIDS clinic counselors who provide 20 or more hours per week of psychosocial support to PLWH/A. The assessment explored their education and training backgrounds, the extent to which evidence-based practices are implemented, and how a decision-support tool can support counselor work practices. Qualitative analysis was organized around seven main categories: counselor characteristics, patient characteristics, barriers, definitions of key concepts, use of guidelines, client assessments, and resources. The resulting coding schemes revealed knowledge and practice gaps among the interviewees, as well as barriers and challenges of counseling. Education and training background of the counseling staff varied widely. When asked to define five key concepts related to HIV counseling, 26-47% of respondents were unable to articulate an adequate definition. Less than half of the interviewees recalled sources of guidelines used in their work and specific models of care introduced during trainings. Interviews identified environmental barriers, language and literacy, patient education, and patient communication as the most prominent challenges to counseling work. The results from this study inform the need for and development of a

  18. Rhizolith evidence in support of a late Holocene sea-level highstand at least 0.5 m higher than present at Key Biscayne, Florida (United States)

    Froede, Carl R., Jr.


    R. Fairbridge and F. Shepard proposed different sea-level curves for the late Holocene. South Florida, as a tectonically stable platform, provides a key locale from which late Quaternary sea-level measurements have been attempted. Previous studies supporting Holocene sea-level curves have focused on mangrove peat deposits, barrier ridges, and archaeological sites. However, in situ biological indicators provide the best evidence in support of varying sea-level positions during the late Holocene. The northeastern side of Key Biscayne, Florida, has two areas of rock reef where rhizoliths (i.e., fossilized root casts) are exposed within the intertidal zone. They have previously been interpreted as the fossilized roots of a former black mangrove (Avicennia germinans) forest. However, the morphology, size, orientation, and areal extent of the rhizoliths is best understood if they are interpreted as the former root casts of turtle grass (Thalassia testudinum). This interpretation would constitute in situ biological evidence of a late Holocene sea-level position at least 0.5 m higher than at present. Previously published 14C dating of the calcareous paste inside the rhizoliths suggests that they formed 1 2 k.y. before present. This corresponds to a higher than present sea-level highstand supported by independent evidence from other areas in south Florida.

  19. SUPPORT Tools for Evidence-informed policymaking in health 6: Using research evidence to address how an option will be implemented

    Directory of Open Access Journals (Sweden)

    Lavis John N


    Full Text Available Abstract This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. After a policy decision has been made, the next key challenge is transforming this stated policy position into practical actions. What strategies, for instance, are available to facilitate effective implementation, and what is known about the effectiveness of such strategies? We suggest five questions that can be considered by policymakers when implementing a health policy or programme. These are: 1. What are the potential barriers to the successful implementation of a new policy? 2. What strategies should be considered in planning the implementation of a new policy in order to facilitate the necessary behavioural changes among healthcare recipients and citizens? 3. What strategies should be considered in planning the implementation of a new policy in order to facilitate the necessary behavioural changes in healthcare professionals? 4. What strategies should be considered in planning the implementation of a new policy in order to facilitate the necessary organisational changes? 5. What strategies should be considered in planning the implementation of a new policy in order to facilitate the necessary systems changes?

  20. Supporting employees' work-family needs improves health care quality: Longitudinal evidence from long-term care. (United States)

    Okechukwu, Cassandra A; Kelly, Erin L; Bacic, Janine; DePasquale, Nicole; Hurtado, David; Kossek, Ellen; Sembajwe, Grace


    We analyzed qualitative and quantitative data from U.S.-based employees in 30 long-term care facilities. Analysis of semi-structured interviews from 154 managers informed quantitative analyses. Quantitative data include 1214 employees' scoring of their supervisors and their organizations on family supportiveness (individual scores and aggregated to facility level), and three outcomes: (1), care quality indicators assessed at facility level (n = 30) and collected monthly for six months after employees' data collection; (2), employees' dichotomous survey response on having additional off-site jobs; and (3), proportion of employees with additional jobs at each facility. Thematic analyses revealed that managers operate within the constraints of an industry that simultaneously: (a) employs low-wage employees with multiple work-family challenges, and (b) has firmly institutionalized goals of prioritizing quality of care and minimizing labor costs. Managers universally described providing work-family support and prioritizing care quality as antithetical to each other. Concerns surfaced that family-supportiveness encouraged employees to work additional jobs off-site, compromising care quality. Multivariable linear regression analysis of facility-level data revealed that higher family-supportive supervision was associated with significant decreases in residents' incidence of all pressure ulcers (-2.62%) and other injuries (-9.79%). Higher family-supportive organizational climate was associated with significant decreases in all falls (-17.94%) and falls with injuries (-7.57%). Managers' concerns about additional jobs were not entirely unwarranted: multivariable logistic regression of employee-level data revealed that among employees with children, having family-supportive supervision was associated with significantly higher likelihood of additional off-site jobs (RR 1.46, 95%CI 1.08-1.99), but family-supportive organizational climate was associated with lower likelihood

  1. A universal velocity dispersion profile for pressure supported systems: evidence for MONDian gravity across 12 orders of magnitude in mass

    CERN Document Server

    Hernandez, X; Cervantes-Sodi, B; Ibarra-Medel, H J; Lopez-Cruz, O


    For any MONDian extended theory of gravity where the rotation curves of spiral galaxies are explained through a change in physics rather than the hypothesis of dark matter, a generic dynamical behaviour is expected for pressure supported systems: an outer flattening of the velocity dispersion profile occurring at a characteristic radius, where both the amplitude of this flat velocity dispersion and the radius at which it appears are predicted to show distinct scalings with the total mass of the system. By carefully analysing dynamics of globular clusters, elliptical galaxies and galaxy clusters, we are able to significantly extend the astronomical scales over which MONDian gravity has been tested, from those of spiral galaxies, to the much larger range covered by pressure supported systems. We show that a universal projected velocity dispersion profile accurately describes various classes of pressure supported systems, and further, that the expectations of extended gravity are met, across twelve orders of mag...

    Collares E.F.


    Full Text Available Dipyrone administered intravenously (iv delays gastric emptying (GE in rats. The objectives of the present study were to assess: 1 the effect of the dose of dipyrone and time after its iv administration on GE in rats, 2 the effect of subdiaphragmatic vagotomy (VgX and bilateral electrolytic lesion of the paraventricular nucleus (PVNX on the delayed GE induced by the drug, and 3 the intracerebroventricular (icv action of dipyrone and of one of its metabolites, 4-aminoantipyrine on GE. Male Wistar rats received saline labeled with phenol red intragastrically as a test meal. GE was indirectly assessed by the determination of percent gastric retention (GR of the test meal 10 min after administration by gavage. Dipyrone delays GE in a dose- and time-dependent manner. Thirty minutes after the iv administration of 80 mg/kg dipyrone, the animals showed significantly higher GR (mean = 62.6% compared to those receiving vehicle (31.5%. VgX and PVNX significantly reduced the iv effect of 80 mg/kg dipyrone (mean %GR: VgX = 28.3 vs Sham = 55.5 and PVNX = 34.5 vs Sham = 52.2. Icv administration of 4 µmol dipyrone caused a significant increase in GR (54.1% of the test meal 10 min later, whereas administration of 4 µmol 4-aminoantipyrine had no effect (34.4%. Although the dipyrone dose administered icv was 16 times lower than that applied iv, for the same time of action (10 min, the GR of animals that received the drug icv (54.1% or iv (54.5% did not differ significantly. In conclusion, the present results suggest that the effect of dipyrone in delaying GE is due to the action of the drug on the central nervous system, with the participation of the PVN and of the vagus nerve.

  4. The Need to Support of Data Flow Graph Visualization of Forensic Lucid Programs, Forensic Evidence, and their Evaluation by GIPSY

    CERN Document Server

    Mokhov, Serguei A; Debbabi, Mourad


    Lucid programs are data-flow programs and can be visually represented as data flow graphs (DFGs) and composed visually. Forensic Lucid, a Lucid dialect, is a language to specify and reason about cyberforensics cases. It includes the encoding of the evidence (representing the context of evaluation) and the crime scene modeling in order to validate claims against the model and perform event reconstruction, potentially within large swaths of digital evidence. To aid investigators to model the scene and evaluate it, instead of typing a Forensic Lucid program, we propose to expand the design and implementation of the Lucid DFG programming onto Forensic Lucid case modeling and specification to enhance the usability of the language and the system.

  12. Enhanced central serotonin release from slices of rat hypothalamus following repeated nialamide administration: evidence supporting the overactive serotonin receptor theory of depression

    Energy Technology Data Exchange (ETDEWEB)

    Offord, S.J.


    Researchers are suggesting unipolar affective disorders may be related to an abnormality in biogenic amine receptor-sensitivity. This abnormality may be a result of a dysfunction in central serotonin (5-HT) release mechanisms. 5-HT neurotransmission is modulated by presynaptic autoreceptors, which are members of the 5-HT/sub 1/ receptor subtype. The autoreceptor is thought to play an important role in the homeostasis of the central 5-HT synapse and could be a site at which some antidepressants mediate their therapeutic effect. The number of 5-HT/sub 1/ type receptor binding sites are reduced and behavior mediated by this receptor is abolished following repeated injections of monoamine oxidase inhibitor type antidepressants. These changes did not occur following a single injection. It was hypothesized that repeated treatment with a monoamine oxidase inhibitor would reduce the sensitivity of 5-HT autoreceptors and enhance 5-HT release. Rats were pretreated with single or repeated (twice daily for 7 days) intraperitoneal injections of nialamide (40 mg/kg) or chlorimipramine (10 mg/kg) and the ability of the autoreceptor agonist to inhibit potassium-induced /sup 3/H-5-HT release was evaluated using an in vitro superfusion system. These changes in 5-HT autoreceptor activity are consistent with other reports evaluating monoamine oxidase inhibitors on 5-HT/sub 1/ type receptors. It is hypothesized that the changes in 5-HT neurotransmission are related to the antidepressant mechanism of monoamine oxidase inhibitors.

  14. Multi-criteria clinical decision support: A primer on the use of multiple criteria decision making methods to promote evidence-based, patient-centered healthcare. (United States)

    Dolan, James G


    Current models of healthcare quality recommend that patient management decisions be evidence-based and patient-centered. Evidence-based decisions require a thorough understanding of current information regarding the natural history of disease and the anticipated outcomes of different management options. Patient-centered decisions incorporate patient preferences, values, and unique personal circumstances into the decision making process and actively involve both patients along with health care providers as much as possible. Fundamentally, therefore, evidence-based, patient-centered decisions are multi-dimensional and typically involve multiple decision makers.Advances in the decision sciences have led to the development of a number of multiple criteria decision making methods. These multi-criteria methods are designed to help people make better choices when faced with complex decisions involving several dimensions. They are especially helpful when there is a need to combine "hard data" with subjective preferences, to make trade-offs between desired outcomes, and to involve multiple decision makers. Evidence-based, patient-centered clinical decision making has all of these characteristics. This close match suggests that clinical decision support systems based on multi-criteria decision making techniques have the potential to enable patients and providers to carry out the tasks required to implement evidence-based, patient-centered care effectively and efficiently in clinical settings.The goal of this paper is to give readers a general introduction to the range of multi-criteria methods available and show how they could be used to support clinical decision-making. Methods discussed include the balance sheet, the even swap method, ordinal ranking methods, direct weighting methods, multi-attribute decision analysis, and the analytic hierarchy process (AHP).

  15. Evidence supporting primary prevention of cardiovascular diseases with statins: Gaps between updated clinical results and actual practice. (United States)

    Bruckert, Eric; Ferrières, Jean


    The use of pharmacological lipid-lowering intervention in individuals with hypercholesterolaemia and known cardiovascular disease or diabetes/chronic kidney disease is well established. Current European Society of Cardiology guidelines recommend immediate initiation of drugs in adjunct to lifestyle intervention in these patients at high or very high cardiovascular risk. In these clinical settings, statins are generally chosen as the first-choice drug intervention, in consideration of the robust evidence showing a reduction in all-cause mortality and major adverse cardiac events (MACE). In contrast, primary prevention with statins, even in the subset of patients at high-risk of cardiovascular events, is not well implemented. This might be related to a lack of public awareness regarding the actual risk associated with prolonged exposure to high concentrations of low-density lipoprotein cholesterol (LDL-C) and uncertainties in the clinical evidence coming from the earliest trials in this patient subset. However, recent observational studies suggest that lowering LDL-C earlier in life and for a longer duration can substantially decrease the burden of cardiovascular disease and mortality. Moreover, results from recent well-conducted large meta-analyses of randomized clinical trials showed that primary prevention with statins reduced all-cause mortality by 14% and MACE by > 20% - findings similar to those observed for the use of statins in secondary prevention. Recently published American Heart Association/American College of Cardiology guidelines on the treatment of blood cholesterol emphasize that primary prevention using high-dose statins in individuals with LDL-C ≥ 190 mg/dL induces a benefit in atherosclerotic cardiovascular risk reduction that clearly exceeds the potential for adverse effects. We aim in this review to discuss the new data that advocate the use of statins in primary prevention earlier and more frequently, putting the efficacy evidence into

  16. Narrative and evidence. How can case studies from the history of science support claims in the philosophy of science? (United States)

    Kinzel, Katherina


    A common method for warranting the historical adequacy of philosophical claims is that of relying on historical case studies. This paper addresses the question as to what evidential support historical case studies can provide to philosophical claims and doctrines. It argues that in order to assess the evidential functions of historical case studies, we first need to understand the methodology involved in producing them. To this end, an account of historical reconstruction that emphasizes the narrative character of historical accounts and the theory-laden character of historical facts is introduced. The main conclusion of this paper is that historical case studies are able to provide philosophical claims with some evidential support, but that, due to theory-ladenness, their evidential import is restricted.

    姜礼平; 刘杨; 胡伟文; 周尧


    To solve the problem of the unrealistic results arising in using Dempster’s method for the combi-nation of highly conflicting evidences,an improved evidence combination method is presented which is based on support degree.First of all,the similarities between evidences are used as an approach to judge whether con-flicts exist.If there are more than 3 evidence combinations with conflicts,the characteristic vector correspon-ding to the maximum characteristic value of the support matrix is used so as to obtain the evidences’support de-gree coefficients.Then,BPA functions are transformed by means of the support degree coefficients.Finally, the Dempster’s method is used for the combination.The stimulation results show that the proposed method can deal with conflicting evidence solve the problem caused by one vote veto effectively,combinations calculate faster than other improved algorithms,reduce uncertainty in recognizing results,and retain the advantages of Dempster’s method.%针对 Dempster 方法在合成高度冲突的证据时结果与直观结论相悖的问题,提出了一种基于支持度的改进证据合成方法。首先根据证据之间的相似性程度判断是否存在证据冲突,对于总数在3条以上且存在冲突的证据组合,应用各证据的支持矩阵,通过其最大特征值对应的特征向量导出各证据的支持度系数,由此对基本概率分配(basic probability assignation,BPA)函数进行转化,再采用 Dempster 方法进行合成。仿真计算结果表明,该方法能有效处理冲突证据组合,克服了一票否决问题,相对于其它几种典型改进算法具有更快的识别速度,能进一步减小识别结果的不确定性,并保留了 Dempster 方法满足交换律、结合律的良好特性。

  19. The Weight of Evidence Does Not Support the Listing of Styrene as “Reasonably Anticipated to be a Human Carcinogen” in NTP's Twelfth Report on Carcinogens (United States)

    Rhomberg, Lorenz R.; Goodman, Julie E.; Prueitt, Robyn L.


    Styrene was listed as “reasonably anticipated to be a human carcinogen” in the twelfth edition of the National Toxicology Program's Report on Carcinogens based on what we contend are erroneous findings of limited evidence of carcinogenicity in humans, sufficient evidence of carcinogenicity in experimental animals, and supporting mechanistic data. The epidemiology studies show no consistent increased incidence of, or mortality from, any type of cancer. In animal studies, increased incidence rates of mostly benign tumors have been observed only in certain strains of one species (mice) and at one tissue site (lung). The lack of concordance of tumor incidence and tumor type among animals (even within the same species) and humans indicates that there has been no particular cancer consistently observed among all available studies. The only plausible mechanism for styrene-induced carcinogenesis—a non-genotoxic mode of action that is specific to the mouse lung—is not relevant to humans. As a whole, the evidence does not support the characterization of styrene as “reasonably anticipated to be a human carcinogen,” and styrene should not be listed in the Report on Carcinogens.

This paper explores how a recovery paradigm offers opportunities to better understand how efforts within the personal, clinical, and psychosocial disability domains of well-being relate and need bridging and integration with an evidence-based framework of practice to optimise outcomes. Recovery from a severe and persisting mental illness such as schizophrenia is optimised by a holistic approach integrating the domains of clinical treatment and psychosocial rehabilitation with the personal efforts of individuals. For service providers, a monolithic or single paradigm approach with an exclusive or predominant biological, psychological, social, or cultural focus is unable to offer effective guidance on the treatment and rehabilitation support needed to enable community participation and ameliorate the impact which problems associated with mental illness have on individuals, their families, and their wider communities. Moreover, recovery-oriented services need to be effective, embracing evidence-based policy, practice and service delivery by providing treatment and support which actually work to improve outcomes for consumers and families.

  1. Is EBE theory supported by the evidence? Is it androcentric? A reply to Peplau et al. (1998) (United States)

    Bem, D J


    In their critique of the author's Exotic-Becomes-Erotic (EBE) theory of sexual orientation (D. J. Bem, 1996), L. A. Peplau, L. D. Garnets, L. R. Spalding, T. D. Conley, and R. C. Veniegas (1998) challenge his reading of the evidence concerning the antecedents of sexual orientation; they also contend that the theory neglects women's experiences. In reply, the author argues that L. A. Peplau et al. have misunderstood the critical antecedent variable of the theory and, hence, have misidentified the particular empirical findings that would serve to confirm or disconfirm its central contentions. The author also argues that the sex differences they cite are not relevant to the theory, whereas an important sex difference they do not cite is actually anticipated by it.

  2. Contributing to a Quality Patient Experience: Applying Evidence Based Practice to Support Changes in Nursing Dress Code Policies (United States)

    West, Margaret Mary; Wantz, Debra; Campbell, Patricia; Rosler, Greta; Troutman, Dawn; Muthler, Crystal


    The public image of nurse professionalism is important. Attributes of a professional nurse, such as caring, attentive, empathetic, efficient, knowledgeable, competent, and approachable, or lack thereof, can contribute positively or negatively to the patient experience. Nurses at a hospital in central northeast Pennsylvania offer their story as they considered the impact of a wide variety of individual uniform and dress choices. This article describes an evidence based practice project and survey created to increase understanding of patient perceptions regarding the professional image of nurses in this facility. Exploring patient perception of nurse image provided insight into what patients view as important. A team approach included the voice of nurses at different levels in the process. Ultimately, this work informed a revision of the health system nursing dress code. The study team also reflects on challenges, next steps in the process, and offers recommendations based on their experiences.

  3. Experimental evidence and modeling studies support a synchronizing role for electrical coupling in the cat thalamic reticular neurons in vivo (United States)

    Fuentealba, Pablo; Crochet, Sylvain; Timofeev, Igor; Bazhenov, Maxim; Sejnowski, Terrence J.; Steriade, Mircea


    Thalamic reticular (RE) neurons are crucially implicated in brain rhythms. Here, we report that RE neurons of adult cats, recorded and stained intracellularly in vivo, displayed spontaneously occurring spikelets, which are characteristic of central neurons that are coupled electrotonically via gap junctions. Spikelets occurred spontaneously during spindles, an oscillation in which RE neurons play a leading role, as well as during interspindle lulls. They were significantly different from excitatory postsynaptic potentials and also distinct from fast prepotentials that are presumably dendritic spikes generated synaptically. Spikelets were strongly reduced by halothane, a blocker of gap junctions. Multi-site extracellular recordings performed before, during and after administration of halothane demonstrated a role for electrical coupling in the synchronization of spindling activity within the RE nucleus. Finally, computational models of RE neurons predicted that gap junctions between these neurons could mediate the spread of low-frequency activity at great distances. These experimental and modeling data suggest that electrotonic coupling within the RE nucleus plays an important role in the generation and synchronization of low-frequency (spindling) activities in the thalamus.

    Full Text Available BACKGROUND: Immunization against influenza is considered an essential public health intervention to control both seasonal epidemics and pandemic influenza. According to the World Health Organization (WHO, there are five key policy and three key programmatic issues that decision-makers should consider before introducing a vaccine. These are (a public health priority, (b disease burden, (c efficacy, quality and safety of the vaccine, (d other inventions, (e economic and financial issues, (f vaccine presentation, (g supply availability and (h programmatic strength. We analyzed the body of evidence currently available on these eight issues in the WHO Western Pacific Region. METHODOLOGY/PRINCIPAL FINDINGS: Studies indexed in PubMed and published in English between 1 January 2000 and 31 December 2010 from the 37 countries and areas of the Western Pacific Region were screened for keywords pertaining to the five policy and three programmatic issues. Studies were grouped according to country income level and vaccine target group. There were 133 articles that met the selection criteria, with most (90% coming from high-income countries. Disease burden (n = 34, vaccine efficacy, quality and safety (n = 27 and public health priority (n = 27 were most frequently addressed by studies conducted in the Region. Many studies assessed influenza vaccine policy and programmatic issues in the general population (42%, in the elderly (24% and in children (17%. Few studies (2% addressed the eight issues relating to pregnant women. CONCLUSIONS/SIGNIFICANCE: The evidence for vaccine introduction in countries and areas in this Region remains limited, particularly in low- and middle-income countries that do not currently have influenza vaccination programmes. Surveillance activities and specialized studies can be used to assess the eight issues including disease burden among vaccine target groups and the cost-effectiveness of influenza vaccine. Multi-country studies should

  5. Iron isotopes in ancient and modern komatiites: Evidence in support of an oxidised mantle from Archean to present (United States)

    Hibbert, K. E. J.; Williams, H. M.; Kerr, A. C.; Puchtel, I. S.


    The mantle of the modern Earth is relatively oxidised compared to the initially reducing conditions inferred for core formation. The timing of the oxidation of the mantle is not conclusively resolved but has important implications for the timing of the development of the hydrosphere and atmosphere. In order to examine the timing of this oxidation event, we present iron isotope data from three exceptionally well preserved komatiite localities, Belingwe (2.7 Ga), Vetreny (2.4 Ga) and Gorgona (0.089 Ga). Measurements of Fe isotope compositions of whole-rock samples are complemented by the analysis of olivine, spinel and pyroxene separates. Bulk-rock and olivine Fe isotope compositions (δ57Fe) define clear linear correlations with indicators of magmatic differentiation (Mg#, Cr#). The mean Fe isotope compositions of the 2.7-2.4 Ga and 0.089 Ga samples are statistically distinct and this difference can be explained by greater extent of partial melting represented by the older samples and higher mantle ambient temperatures in the Archean and early Proterozoic relative to the present day. Significantly, samples of all ages define continuous positive linear correlations between bulk rock δ57Fe and V/Sc and δ57Fe and V, and between V/Sc and V with TiO2, providing evidence for the incompatible behaviour of V (relative to Sc) and of isotopically heavy Fe. Partial melting models calculated using partition coefficients for V at oxygen fugacities (fO2s) of 0 and + 1 relative to the fayalite-magnetite-quartz buffer (FMQ) best match the data arrays, which are defined by all samples, from late Archean to Tertiary. These data, therefore, provide evidence for komatiite generation under moderately oxidising conditions since the late Archean, and argue against a change in mantle fO2 concomitant with atmospheric oxygenation at ~ 2.4 Ga.

    Gianni Cicia


    Full Text Available  Urbanisation of city-side areas effects on farm land use and organisation are analysed in this study with the objective of seeking the most effective way to implement a Community Supported Agriculture (CSA scheme. Specifically, we used a theoretical framework to describe and assess the relationships between urbanization and farm-styles in the city belt. Our analysis is based on a case study in the protected area of the Campi Flegrei Regional Park situated in the north-western part of the Neapolitan metropolitan area, which is a peri-urban rural area with severe environmental management problems. Our results from the empirical analysis allowed us to distinguish the farms of the area into three behavioural-social groups on the basis of specific features, in order to identify the best suited type of farm for the strategic implementation of the CSA. A market scenario was predicted for each of them without any intervention

    Full Text Available The SMEs’ access to finance is crucial for the creation, survival and growth of these firms. In the light of the recent global crisis, the dramatic fall in demand for goods and services and the reduced availability of bank loans has led to the aggravation of the problems faced by SMEs when they prospect for purchasing financial resources. In this context, our paper aims to highlight the sources of financing used by the European SMEs and the new policies proposed by the European Commission to facilitate their access to finance. The analysis carried out in this paper is based on data and statistics provided mainly by the European Commission and the World Bank. Based on the methodology used, the paper mainly indicates, the major problems regarding the financing opportunities faced by SMEs and the indispensable necessity for the adoption of measures, especially at EU level, to support their access to finance.

  11. Supporting implementation of evidence-based behavioral interventions: the role of data liquidity in facilitating translational behavioral medicine. (United States)

    Abernethy, Amy P; Wheeler, Jane L; Courtney, Paul K; Keefe, Francis J


    The advancement of translational behavioral medicine will require that we discover new methods of managing large volumes of data from disparate sources such as disease surveillance systems, public health systems, and health information systems containing patient-centered data informed by behavioral and social sciences. The term "liquidity," when applied to data, refers to its availability and free flow throughout human/computer interactions. In seeking to achieve liquidity, the focus is not on creating a single, comprehensive database or set of coordinated datasets, nor is it solely on developing the electronic health record as the "one-stop shopping" source of health-related data. Rather, attention is on ensuring the availability of secure data through the various methods of collecting and storing data currently existent or under development-so that these components of the health information infrastructure together support a liquid data system. The value of accessible, interoperable, high-volume, reliable, secure, and contextually appropriate data is becoming apparent in many areas of the healthcare system, and health information liquidity is currently viewed as an important component of a patient-centered healthcare system. The translation from research interventions to behavioral and psychosocial indicators challenges the designers of healthcare systems to include this new set of data in the correct context. With the intention of advancing translational behavioral medicine at the local level, "on the ground" in the clinical office and research institution, this commentary discusses data liquidity from the patient's and clinician's perspective, requirements for a liquid healthcare data system, and the ways in which data liquidity can support translational behavioral medicine.

  12. Evidence that interfibrillar load transfer in tendon is supported by small diameter fibrils and not extrafibrillar tissue components. (United States)

    Szczesny, Spencer E; Fetchko, Kristen L; Dodge, George R; Elliott, Dawn M


    Collagen fibrils in tendon are believed to be discontinuous and transfer tensile loads through shear forces generated during interfibrillar sliding. However, the structures that transmit these interfibrillar forces are unknown. Various extrafibrillar tissue components (e.g., glycosaminoglycans, collagens XII and XIV) have been suggested to transmit interfibrillar loads by bridging collagen fibrils. Alternatively, collagen fibrils may interact directly through physical fusions and interfibrillar branching. The objective of this study was to test whether extrafibrillar proteins are necessary to transmit load between collagen fibrils or if interfibrillar load transfer is accomplished directly by the fibrils themselves. Trypsin digestions were used to remove a broad spectrum of extrafibrillar proteins and measure their contribution to the multiscale mechanics of rat tail tendon fascicles. Additionally, images obtained from serial block-face scanning electron microscopy were used to determine the three-dimensional fibrillar organization in tendon fascicles and identify any potential interfibrillar interactions. While trypsin successfully removed several extrafibrillar tissue components, there was no change in the macroscale fascicle mechanics or fibril:tissue strain ratio. Furthermore, the imaging data suggested that a network of smaller diameter fibrils (wind around and fuse with their neighboring larger diameter fibrils. These findings demonstrate that interfibrillar load transfer is not supported by extrafibrillar tissue components and support the hypothesis that collagen fibrils are capable of transmitting loads themselves. Conclusively determining how fibrils bear load within tendon is critical for identifying the mechanisms that impair tissue function with degeneration and for restoring tissue properties via cell-mediated regeneration or engineered tissue replacements. © 2017 Orthopaedic Research Society.

  13. Molecular evidence indicates that subarctic willow communities in Scotland support a diversity of host-associated Melampsora rust taxa. (United States)

    Milne, Jeremy M; Helfer, Stephan; Kirk, Calum; Hollingsworth, Peter M; Ennos, Richard A


    Rare and threatened subarctic willow scrub communities in the UK are the subject of ongoing conservation programmes, yet little is known about the diversity of fungal taxa that they support. Isolates of the rust genus Melampsora were sampled from 112 leaves of eight subarctic willow (Salix) taxa and their hybrids from twelve sites in the UK. In order to determine the number of Melampsora taxa present in the samples, isolates were sequenced for the Internal Transcribed Spacer (ITS) region of rDNA and data were subject to phylogenetic analysis. Maximum likelihood and Bayesian analysis indicated that the isolates fell into three strongly supported host-associated clades. Clade I contained only isolates from Salix herbacea and was distinguished morphologically by dense urediniospore echinulation and thin cell walls. Clade II contained isolates from Salix arbuscula and Salix reticulata only. These could not be distinguished morphologically from isolates in Clade III which were found on Salix lapponum, Salix myrsinites, Salix myrsinifolia, Salix aurita, Salix lanata, and their hybrids. Clade II was most distinct in ITS sequence, differing by 50 bases from Clades I and III, while the latter clades differed in sequence by only 24 bases on average. Clades I and III are likely to represent the previously recognised taxa Melampsora alpina Juel 1894 and Melampsora epitea Thüm. 1879 respectively, but Clade II has not apparently been described before. Significant differences in the intensity of infection by isolates of Clade III were found among different Salix species at a single site, suggesting either differences in resistance among Salix taxa, or the presence of further cryptic taxa within Clade III. The study illustrates the power of molecular phylogenetic analysis to reveal cryptic biodiversity within Melampsora, and suggests that conserving Salix host diversity within subarctic willow communities will ensure that a diversity of associated Melampsora taxa is maintained.

  14. Integration of Administrative, Clinical, and Environmental Data to Support the Management of Type 2 Diabetes Mellitus: From Satellites to Clinical Care. (United States)

    Dagliati, Arianna; Marinoni, Andrea; Cerra, Carlo; Decata, Pasquale; Chiovato, Luca; Gamba, Paolo; Bellazzi, Riccardo


    A very interesting perspective of "big data" in diabetes management stands in the integration of environmental information with data gathered for clinical and administrative purposes, to increase the capability of understanding spatial and temporal patterns of diseases. Within the MOSAIC project, funded by the European Union with the goal to design new diabetes analytics, we have jointly analyzed a clinical-administrative dataset of nearly 1.000 type 2 diabetes patients with environmental information derived from air quality maps acquired from remote sensing (satellite) data. Within this context we have adopted a general analysis framework able to deal with a large variety of temporal, geo-localized data. Thanks to the exploitation of time series analysis and satellite images processing, we studied whether glycemic control showed seasonal variations and if they have a spatiotemporal correlation with air pollution maps. We observed a link between the seasonal trends of glycated hemoglobin and air pollution in some of the considered geographic areas. Such findings will need future investigations for further confirmation. This work shows that it is possible to successfully deal with big data by implementing new analytics and how their exploration may provide new scenarios to better understand clinical phenomena.

  15. Preclinical evidence supporting the clinical development of central pattern generator-modulating therapies for chronic spinal cord-injured patients

    Directory of Open Access Journals (Sweden)

    Pierre eGuertin


    Full Text Available Ambulation or walking is one of the main gaits of locomotion. In terrestrial animals, it may be defined as a series of rhythmic and bilaterally coordinated movement of the limbs which creates a forward movement of the body. This applies regardless of the number of limbs - from arthropods with six or more limbs to bipedal primates. These fundamental similarities among species may explain why comparable neural systems and cellular properties have been found, thus far, to control in similar ways locomotor rhythm generation in most animal models. The aim of this article is to provide a comprehensive review of the known structural and functional features associated with central nervous system (CNS networks that are involved in the control of ambulation and other stereotyped motor patterns - specifically Central Pattern Generators (CPGs that produce basic rhythmic patterned outputs for locomotion, micturition, ejaculation, and defecation. Although there is compelling evidence of their existence in humans, CPGs have been most studied in reduced models including in vitro isolated preparations, genetically-engineered mice and spinal cord-transected animals. Compared with other structures of the CNS, the spinal cord is generally considered as being well-preserved phylogenetically. As such, most animal models of SCI should be considered as valuable tools for the development of novel pharmacological strategies aimed at modulating spinal activity and restoring corresponding functions in chronic spinal cord-injured patients.

  16. Calcium-sensitive modulation of Ig capping: evidence supporting a cytoplasmic control of ligand-receptor complexes. (United States)

    Schreiner, G F; Unanue, E R


    Capping of anti-Ig-Ig complexes was studied in murine B lymphocytes. Morphological studies indicated that caps formed rapidly on cells before any changes in shape. The first changes in cell shape were evident as a contraction right under the cap area. The removal of extracellular calcium had no effect on cap formation. Furthermore, the introduction of calcium by the ionophore A-23187 stopped capping. The ionophere by itself in the absence of extracellular calcium had no effect. Caps were found to be disrupted, the complexes scattering over the entire cell surface if the cells were treated by A-23187 after the caps had formed. The disruptive effect of A-23187 as dependent on extracellular calcium and could be stopped by drugs that affected energy metabolism. The cytochalasins also disrupted the formed caps. Drugs that affect energy metabolism by themselves did not disrupt the caps. We interpret the effects of the ionophore as resulting from a systemic hypercontractility of microfilaments. A theory for explaining the formation and disruption of capping is discussed.

  17. Sclereids are strong enough to support the delicate corollas: experimental and computational data evidence from Camellia sinensis (L.) (United States)

    Zhang, Wei; Xue, Yuanyuan; Yang, Shuo; Wang, Yangang; Zhao, Hong


    Sclereids are a fundamental cell type that widely exist in higher plants and are generally thought to have a mechanical function. However, the occurrence of sclereids in the ephemeral corolla has rarely been documented and their biological significance is poorly understood. In this study, flower buds from Camellia sinensis at various ontogenetic stages were sampled, cleared, sectioned, stained, and examined using light microscopy to ascertain the morphology and distribution of sclereids and their variation. In addition, Camellia japonica plants with distinctive floral structures were investigated and compared to explore whether sclereid occurrence is associated with floral form. In particular, a computational simulation using finite element analysis was undertaken to investigate how corollas, with and without sclereids, responded to wind and rain. The results showed that sclereids have some mechanical properties that are based on their shape and distribution, which make the soft corolla strong enough to protect the inner ovary. Thus, corolla sclereids may explain how the seemingly delicate corolla performs its protective function in response to environmental stresses. These findings provide further evidence for the hypothesis that flower traits exhibit adaptive responses to abiotic factors in addition to their traditionally recognized pollinator-mediated selection.

  19. Rethinking the role of worry in generalized anxiety disorder: evidence supporting a model of emotional contrast avoidance. (United States)

    Llera, Sandra J; Newman, Michelle G


    The Contrast Avoidance model (Newman & Llera, 2011) proposes that individuals with generalized anxiety disorder (GAD) are hypersensitive to sharp upward shifts in negative emotion that typically accompany negative events, and use worry to maintain sustained intrapersonal negativity in an attempt to avoid these shifts. Although research shows that worry increases negative emotionality and mutes further emotional reactivity to a stressor when compared to the worry period (e.g., Llera & Newman, 2010), no study has tracked changes in negative emotionality from baseline to worry inductions followed by a range of emotional exposures. Further, no study has yet assessed participants' subjective appraisals of prior worry on helping to cope with such exposures. The present study tested the main tenets of the Contrast Avoidance model by randomly assigning participants with GAD (n=48) and nonanxious controls (n=47) to experience worry, relaxation, and neutral inductions prior to sequential exposure to fearful, sad, and humorous film clips. Both physiological (nonspecific skin conductance responses [NS-SCRs]) and self-reported emotional changes were observed. Results indicated that worry boosted negative emotionality from baseline, which was sustained across negative exposures, whereas low negative emotionality during relaxation and neutral inductions allowed for sharp increases in response to exposures. Furthermore, GAD participants found worry to be more helpful than other conditions in coping with exposures, whereas control participants reported the opposite pattern. Results provide preliminary support for the Contrast Avoidance model. This suggests that treatment should focus on underlying avoidance patterns before attempting to reduce worry behavior.

  20. Short-term memory for serial order supports vocabulary development: new evidence from a novel word learning paradigm. (United States)

    Majerus, Steve; Boukebza, Claire


    Although recent studies suggest a strong association between short-term memory (STM) for serial order and lexical development, the precise mechanisms linking the two domains remain to be determined. This study explored the nature of these mechanisms via a microanalysis of performance on serial order STM and novel word learning tasks. In the experiment, 6- and 7-year-old children were administered tasks maximizing STM for either item or serial order information as well as paired-associate learning tasks involving the learning of novel words, visual symbols, or familiar word pair associations. Learning abilities for novel words were specifically predicted by serial order STM abilities. A measure estimating the precision of serial order coding predicted the rate of correct repetitions and the rate of phoneme migration errors during the novel word learning process. In line with recent theoretical accounts, these results suggest that serial order STM supports vocabulary development via ordered and detailed reactivation of the novel phonological sequences that characterize new words.

  1. The Right Hemisphere Planum Temporale Supports Enhanced Visual Motion Detection Ability in Deaf People: Evidence from Cortical Thickness

    Directory of Open Access Journals (Sweden)

    Martha M. Shiell


    Full Text Available After sensory loss, the deprived cortex can reorganize to process information from the remaining modalities, a phenomenon known as cross-modal reorganization. In blind people this cross-modal processing supports compensatory behavioural enhancements in the nondeprived modalities. Deaf people also show some compensatory visual enhancements, but a direct relationship between these abilities and cross-modally reorganized auditory cortex has only been established in an animal model, the congenitally deaf cat, and not in humans. Using T1-weighted magnetic resonance imaging, we measured cortical thickness in the planum temporale, Heschl’s gyrus and sulcus, the middle temporal area MT+, and the calcarine sulcus, in early-deaf persons. We tested for a correlation between this measure and visual motion detection thresholds, a visual function where deaf people show enhancements as compared to hearing. We found that the cortical thickness of a region in the right hemisphere planum temporale, typically an auditory region, was greater in deaf individuals with better visual motion detection thresholds. This same region has previously been implicated in functional imaging studies as important for functional reorganization. The structure-behaviour correlation observed here demonstrates this area’s involvement in compensatory vision and indicates an anatomical correlate, increased cortical thickness, of cross-modal plasticity.

    Hernán-Obispo, M; Gálvez-Ortiz, M C; Golovin, A; Barnes, J R; Jones, H R A; Kane, S R; Pinfield, D; Jenkins, J S; Petit, P; Anglada-Escudé, G; Marsden, S C; Catalán, S; Jeffers, S V; de Castro, E; Cornide, M; Garcés, A; Jones, M I; Gorlova, N; Andreev, M


    This paper presents the simultaneous Bayesian analysis of the radial velocity and activity indices for the K5Ve active star BD+20 1790, that was proposed to host a close-in massive planet by Hern\\'an-Obispo et al. (2010). The Bayesian analysis supports the hypothesis of a planetary companion. We present a new orbital solution after removing the two main contributions to the stellar jitter, one that varies with the photometric period and another that varies with the synodic period of the star+planet system. We use a new method to determine these jitter components, considering them as a second and third signals in the system. A discussion on possible magnetic star-planet-interaction is included, based on the Bayesian analysis of the activity indices. We propose two possible sources for flare events of this star: one related to the geometry of the system and the relative movement of the star+planet, and a second one purely stochastic source that is related to the evolution of stellar active regions. Also, we obs...

  4. Evidence-based radiology (part 2): Is there sufficient research to support the use of therapeutic injections into the peripheral joints?

    Energy Technology Data Exchange (ETDEWEB)

    Peterson, Cynthia; Hodler, Juerg [Orthopaedic University Hospital of Balgrist, Radiology, Zuerich (Switzerland)


    This review article addresses the best evidence currently available for the effectiveness of injection therapy for musculoskeletal conditions involving the peripheral joints. The research is presented by anatomical region and areas of controversy and the need for additional research are identified. Randomized controlled trials, meta-analyses and systematic reviews are lacking that address the effectiveness of therapeutic injections to the sternoclavicular, acromioclavicular, ankle and foot joints. No research studies of any kind have been reported for therapeutic injections of the sternoclavicular joint. With the exception of the knee, possibly the hip and patients with inflammatory arthropathies, research does not unequivocally support the use of therapeutic joint injections for most of the peripheral joints, including the shoulder. Additionally, controversy exists in some areas as to whether or not corticosteroids provide better outcomes compared to local anesthetic injections alone. When viscosupplementation injections are compared to corticosteroids in patients with osteoarthritis of the knee, the evidence supports the use of viscosupplementation for more prolonged improvement in outcomes, with corticosteroids being good for short-term relief.

    Sprouse, B.S.


    The purpose of this paper is to describe the development of an administrative record (AR) file system for the Hanford Site in Richland, Washington. This paper will focus on the background of the AR system and its implementation at the Hanford Site; the types of documents to be included in an AR file; the management system used to develop and implement the AR system; the unique characteristics of the AR system and the role of the information repositories. The objective of this session is to present the methodology used in developing an AR and information repository system so that common hurdles from various sites can be addressed and resolved similarly. Therefore unnecessary effort does not have to be put forth to resolve the same issues over and over again. The concepts described can be applied to all federal facility sites with a minimum amount of modification and revision. 9 refs.

  6. Jellyfish support high energy intake of leatherback sea turtles (Dermochelys coriacea: video evidence from animal-borne cameras.

    Directory of Open Access Journals (Sweden)

    Susan G Heaslip

    Full Text Available The endangered leatherback turtle is a large, highly migratory marine predator that inexplicably relies upon a diet of low-energy gelatinous zooplankton. The location of these prey may be predictable at large oceanographic scales, given that leatherback turtles perform long distance migrations (1000s of km from nesting beaches to high latitude foraging grounds. However, little is known about the profitability of this migration and foraging strategy. We used GPS location data and video from animal-borne cameras to examine how prey characteristics (i.e., prey size, prey type, prey encounter rate correlate with the daytime foraging behavior of leatherbacks (n = 19 in shelf waters off Cape Breton Island, NS, Canada, during August and September. Video was recorded continuously, averaged 1:53 h per turtle (range 0:08-3:38 h, and documented a total of 601 prey captures. Lion's mane jellyfish (Cyanea capillata was the dominant prey (83-100%, but moon jellyfish (Aurelia aurita were also consumed. Turtles approached and attacked most jellyfish within the camera's field of view and appeared to consume prey completely. There was no significant relationship between encounter rate and dive duration (p = 0.74, linear mixed-effects models. Handling time increased with prey size regardless of prey species (p = 0.0001.

  8. Mitochondrial DNA phylogeography of lake cisco (Coregonus artedi): evidence supporting extensive secondary contacts between two glacial races. (United States)

    Turgeon, J; Bernatchez, L


    The comparative molecular phylogeography of regional fish fauna has revealed the wide distribution of young clades in freshwater fishes of formerly glaciated areas as well as interspecific incongruences in their refugial origins and recolonization routes. In this study, we employed single-strand conformation polymorphism (SSCP) and sequence analyses to describe mitochondrial DNA (mtDNA) polymorphism among 27 populations of the lake cisco (Coregonus artedi) from its entire range of distribution in order to evaluate the hypothesis of dual glacial refuges proposed by Bernatchez & Dodson against the traditional view that this species is solely of Mississippian origin. Results indicate that this taxon is composed of two closely related groups that are widely distributed and intermixed over most of the sampled range. The estimated level of divergence (0.48%), the contrast in the geographical distribution of each group, as well as the general distribution of C. artedi in North America together support the hypothesis that one group dispersed from a Mississippian refuge via the proglacial lakes, while the other is of Atlantic origin and also took advantages of earlier dispersal routes towards eastern Hudson Bay drainages. However, the signal of past range fragmentation revealed by a nested clade analysis was weak, and did not allow to formally exclude the hypothesis of a single Mississippian origin for both lineages. Comparisons with the phylogeographic patterns of other Nearctic freshwater fishes suggest that the salinity tolerance and thermal sensitivity of lake cisco may have been determinant for its extensive postglacial dispersal. The presence or co-occurrence of sympatric or allopatric eco/morphotypes were not found to be necessarily associated with the presence of both haplotype groups.

  9. Evidence supporting the role of calpain in the α-processing of amyloid-β precursor protein. (United States)

    Nguyen, Huey T; Sawmiller, Darrell R; Wu, Qi; Maleski, Jerome J; Chen, Ming


    Amyloid plaques are a hallmark of the aging and senile dementia brains, yet their mechanism of origins has remained elusive. A central issue is the regulatory mechanism and identity of α-secretase, a protease responsible for α-processing of amyloid-β precursor protein (APP). A remarkable feature of this enzyme is its high sensitivity to a wide range of cellular stimulators, many of which are agonists for Ca(2+) signaling. This feature, together with previous work in our laboratory, has suggested that calpain, a Ca(2+)-dependent protease, plays a key role in APP α-processing. In this study we report that overexpression of the μ-calpain gene in HEK293 cells resulted in a 2.7-fold increase of the protein levels. Measurements of intracellular calpain enzymatic activity revealed that the calpain overexpressing cells displayed a prominent elevation of the activity compared to wild-type cells. When the cells were stimulated by nicotine, glutamate or phorbol 12,13-dibutylester, the activity increase was even more remarkable and sensitive to calpeptin, a calpain inhibitor. Meanwhile, APP secretion from the calpain overexpressing cells was robustly increased under both resting and stimulated conditions over wild-type cells. Furthermore, cell surface biotinylation experiments showed that μ-calpain was clearly detected among the cell surface proteins. These data together support our view that calpain should be a reasonable candidate for α-secretase for further study. This model is discussed with an interesting fact that three other deposited proteins (tau, spectrin and crystalline) are also the known substrates of calpain. Finally we discuss some current misconceptions in senile dementia research.

  10. Supporting middle school students' construction of evidence-based arguments: Impact of and student interactions with computer-based argumentation scaffolds (United States)

    Belland, Brian Robert

    Middle school students have difficulty creating evidence-based arguments (EBAs) during problem-based learning (PBL) units due to challenges (a) adequately representing the unit's central problem (Ge & Land, 2004; Liu & Bera, 2005), (b) determining and obtaining the most relevant evidence (Pedersen & Liu, 2002-2003), and (c) synthesizing gathered information to construct a sound argument (Cho & Jonassen, 2002). I designed and developed the Connection Log to support middle school students in this process. This study addressed (1) the Connection Log's impact on (a) argument evaluation ability, and (b) group argument quality and (2) how and why middle school science students used the Connection Log. Four sections of a 7th-grade science class participated. Student groups selected a stakeholder position related to the Human Genome Project (HGP) and needed to decide on and promote a plan to use $3 million to further their position as pertains to the HGP. I randomly assigned one higher-achieving and one lower-achieving class to Connection Log or no Connection Log conditions. Students completed an argument evaluation test, and impact on argument evaluation ability was determined using nested ANOVA. Two graduate students, blind to treatment conditions, rated group arguments, and impact on group argument quality was determined using nested MANOVA. To determine how and why students used the Connection Log, I videotaped and interviewed one small group from each class in the experimental condition. I coded transcripts and generated themes, triangulating the two data sources with informal observations during all class sessions and what students wrote in the Connection Log. I detected no significant differences on claim, evidence, or connection of claim to evidence ratings of debate performances. However, students used the Connection Log to counter different difficulties, and I found a significant main effect of the Connection Log on argument evaluation ability, as well as a

    Otero-Rodiño, Cristina; Velasco, Cristina; Álvarez-Otero, Rosa; López-Patiño, Marcos A; Míguez, Jesús M; Soengas, José L


    We previously obtained evidence in rainbow trout peripheral tissues such as liver and Brockmann bodies (BB) for the presence and response to changes in circulating levels of glucose (induced by intraperitoneal hypoglycaemic and hyperglycaemic treatments) of glucosensing mechanisms others than that mediated by glucokinase (GK). There were based on mitochondrial production of reactive oxygen species (ROS) leading to increased expression of uncoupling protein 2 (UCP2), and sweet taste receptor in liver and BB, and on liver X receptor (LXR) and sodium/glucose co-transporter 1 (SGLT-1) in BB. We aimed in the present study to obtain further in vitro evidence for the presence and functioning of these systems. In a first experiment, pools of sliced liver and BB were incubated for 6h at 15°C in modified Hanks' medium containing 2, 4, or 8mM d-glucose, and we assessed the response of parameters related to these glucosensing mechanisms. In a second experiment, pools of sliced liver and BB were incubated for 6h at 15°C in modified Hanks' medium with 8mM d-glucose alone (control) or containing 1mM phloridzin (SGLT-1 antagonist), 20μM genipin (UCP2 inhibitor), 1μM trolox (ROS scavenger), 100μM bezafibrate (T1R3 inhibitor), and 50μM geranyl-geranyl pyrophosphate (LXR inhibitor). The results obtained in both experiments support the presence and functioning of glucosensor mechanisms in liver based on sweet taste receptor whereas in BB the evidence support those based on LXR, mitochondrial activity and sweet taste receptor.

  13. Is tattooing a risk factor for adolescents' criminal behavior? Empirical evidence from an administrative data set of juvenile detainees in Taiwan. (United States)

    Liao, Pei-An; Chang, Hung-Hao; Su, Yi-Ju


    Juvenile crime affects not only the victims of the crime but also the delinquents' future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents' criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents' high probability of committing crimes.

  14. Effect of constant administration of a gonadotropin-releasing hormone agonist on reproductive activity in mares: preliminary evidence on suppression of ovulation during the breeding season. (United States)

    Fitzgerald, B P; Peterson, K D; Silvia, P J


    During the breeding season, the effect of constant administration of an agonist analog of gonadotropin-releasing hormone (GnRH; goserelin acetate) on reproductive activity of mares was determined. Twenty-four mares undergoing estrous cycles were allocated at random to 6 groups (n = 4/group) and, on May 29 (day 0), received no treatment (group 1, controls), 120 micrograms (group 2), 360 micrograms (group 3), 600 micrograms (group 4), or 1,200 micrograms (group 5) of GnRH agonist/d for 28 days via a depot implanted subcutaneously. The final group of mares (group 6) was treated with 120 micrograms of GnRH agonist/d for 84 days (3 occasions at 28-day intervals). During a pretreatment period (April 19 to May 29) and for 90 days after initiation of GnRH agonist treatment, follicular development and ovulation were monitored by transrectal ultrasonography of the reproductive tract at 2- to 3-day intervals. On each occasion a blood sample was collected for determination of luteinizing hormone (LH) and progesterone. Estrous behavior was monitored by teasing of mares with a stallion. Initiation of agonist treatment was random, relative to the stage of the estrous cycle, and all mares ovulated within 11 days before or after implantation. In 3 of 4 nontreated control mares, estrous cycles were observed throughout the study, with interovulatory intervals ranging from 18 to 26 days. In the remaining mare, concentration of progesterone was high after asynchronous double ovulation during the pretreatment period, suggestive of persistent corpus luteum.(ABSTRACT TRUNCATED AT 250 WORDS)

  16. Does mass drug administration for the integrated treatment of neglected tropical diseases really work? Assessing evidence for the control of schistosomiasis and soil-transmitted helminths in Uganda

    Directory of Open Access Journals (Sweden)

    Allen Tim


    Full Text Available Abstract Background Less is known about mass drug administration [MDA] for neglected tropical diseases [NTDs] than is suggested by those so vigorously promoting expansion of the approach. This paper fills an important gap: it draws upon local level research to examine the roll out of treatment for two NTDs, schistosomiasis and soil-transmitted helminths, in Uganda. Methods Ethnographic research was undertaken over a period of four years between 2005-2009 in north-west and south-east Uganda. In addition to participant observation, survey data recording self-reported take-up of drugs for schistosomiasis, soil-transmitted helminths and, where relevant, lymphatic filariasis and onchocerciasis was collected from a random sample of at least 10% of households at study locations. Data recording the take-up of drugs in Ministry of Health registers for NTDs were analysed in the light of these ethnographic and social survey data. Results The comparative analysis of the take-up of drugs among adults revealed that although most long term residents have been offered treatment at least once since 2004, the actual take up of drugs for schistosomiasis and soil-transmitted helminths varies considerably from one district to another and often also within districts. The specific reasons why MDA succeeds in some locations and falters in others relates to local dynamics. Issues such as population movement across borders, changing food supply, relations between drug distributors and targeted groups, rumours and conspiracy theories about the 'real' purpose of treatment, subjective experiences of side effects from treatment, alternative understandings of affliction, responses to social control measures and historical experiences of public health control measures, can all make a huge difference. The paper highlights the need to adapt MDA to local circumstances. It also points to specific generalisable issues, notably with respect to health education, drug distribution and

  17. Is there sufficient evidence to support the long-term efficacy of mineral trioxide aggregate (MTA) for endodontic therapy in primary teeth? (United States)

    Anthonappa, R P; King, N M; Martens, L C


    Several papers have been published to illustrate the effectiveness of mineral trioxide aggregate (MTA) as a pulpotomy medicament. Most of these reports do not offer a critical assessment on the data quality. Therefore, this review evaluated whether the currently available evidence is of an appropriate quality to support the long-term effectiveness of MTA as a pulpotomy medicament in primary molars using a standardized assessment criterion. A comprehensive literature search of human clinical outcome studies, which employed MTA as a pulpotomy medicament in primary teeth, was conducted using the MEDLINE database. Two independent observers rated these articles using the standardized assessment criteria. Furthermore, based on the initial sample mentioned in the individual studies and the sample included for the final analysis, the drop-out rates were calculated. Twenty-two studies were included for quality assessment with an excellent interobserver agreement. None of the 22 studies obtained grade A, four studies attained grade B1, five were graded B2 and 13 received grade C. Based on the assessment criteria employed, there was no evidence that MTA was better than present materials and techniques as a pulpotomy medicament. Furthermore, given the low quality of data, it is highly desirable to establish standard requisites for conducting and reporting on pulp therapy studies in primary teeth so as to benefit both researchers and clinicians to produce high-quality studies that are comparable and to prevent the misuse of clinical material and resources.

  18. An examination of the evidence supporting the association of dietary cholesterol and saturated fats with serum cholesterol and development of coronary heart disease. (United States)

    Volk, Marion G


    The lipid hypothesis is the basis for much of the contemporary diet advice and drug therapy aimed at preventing coronary heart disease (CHD), and was developed from a sequential association of dietary lipids, cholesterol, and CHD nearly 100 years ago. The lipid hypothesis considers pathological changes that relate to the end stage of the complex chronic condition summarized as CHD, not to its genesis. Ongoing research provides only inconclusive evidence of the effects of modification of total, saturated, monounsaturated, or polyunsaturated fats on cardiovascular morbidity and mortality. 3-Hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitors or statins, the highest selling drugs in medical history, may provide evidence that the lipid hypothesis is based on erroneous assumptions, since some of the mechanisms of action of statins seem to be independent of cholesterol reduction. This article assesses the methodology and assumptions underlying the early studies that gave rise to the current assumption of a causal relationship between dietary fat consumption and CHD. It argues that flaws in methodology have led to inaccurate and highly debatable conclusions. It assesses research supporting criticism of these early studies and considers other factors that may influence CHD. It offers alternative interpretations of the use of statins in controlling CHD. Finally, it provides an historical context suggesting different causes of CHD that have no relation to fat intake.

  19. Timing of Administration: For Commonly-Prescribed Medicines in Australia

    Directory of Open Access Journals (Sweden)

    Gagandeep Kaur


    Full Text Available Chronotherapy involves the administration of medication in coordination with the body’s circadian rhythms to maximise therapeutic effectiveness and minimise/avoid adverse effects. The aim of this study is to investigate the “time of administration” recommendations on chronotherapy for commonly-prescribed medicines in Australia. This study also aimed to explore the quality of information on the timing of administration presented in drug information sources, such as consumer medicine information (CMI and approved product information (PI. Databases were searched for original research studies reporting on the impact of “time of administration” of the 30 most commonly-prescribed medicines in Australia for 2014. Further, time of administration recommendations from drug information sources were compared to the evidence from chronotherapy trials. Our search revealed 27 research studies, matching the inclusion and exclusion criteria. In 56% (n = 15 of the research studies, the therapeutic effect of the medicine varied with the time of administration, i.e., supported chronotherapy. For some medicines (e.g., simvastatin, circadian-based optimal administration time was evident in the information sources. Overall, dedicated studies on the timing of administration of medicines are sparse, and more studies are required. As it stands, information provision to consumers and health professionals about the optimal “time” to take medications lags behind emerging evidence.

  2. Evidence from case-control and longitudinal studies supports associations of genetic variation in APOE, CETP, and IL6 with human longevity. (United States)

    Soerensen, Mette; Dato, Serena; Tan, Qihua; Thinggaard, Mikael; Kleindorp, Rabea; Beekman, Marian; Suchiman, H Eka D; Jacobsen, Rune; McGue, Matt; Stevnsner, Tinna; Bohr, Vilhelm A; de Craen, Anton J M; Westendorp, Rudi G J; Schreiber, Stefan; Slagboom, P Eline; Nebel, Almut; Vaupel, James W; Christensen, Kaare; Christiansen, Lene


    In this study, we investigated 102 single-nucleotide polymorphisms (SNPs) covering the common genetic variation in 16 genes recurrently regarded as candidates for human longevity: APOE; ACE; CETP; HFE; IL6; IL6R; MTHFR; TGFB1; APOA4; APOC3; SIRTs 1, 3, 6; and HSPAs 1A, 1L, 14. In a case-control study of 1,089 oldest-old (ages 92-93) and 736 middle-aged Danes, the minor allele frequency (MAF) of rs769449 (APOE) was significantly decreased in the oldest-old, while the MAF of rs9923854 (CETP) was significantly enriched. These effects were supported when investigating 1,613 oldest-old (ages 95-110) and 1,104 middle-aged Germans. rs769449 was in modest linkage equilibrium (R (2)=0.55) with rs429358 of the APOE-ε4 haplotype and adjusting for rs429358 eliminated the association of rs769449, indicating that the association likely reflects the well-known effect of rs429358. Gene-based analysis confirmed the effects of variation in APOE and CETP and furthermore pointed to HSPA14 as a longevity gene. In a longitudinal study with 11 years of follow-up on survival in the oldest-old Danes, only one SNP, rs2069827 (IL6), was borderline significantly associated with survival from age 92 (P-corrected=0.064). This advantageous effect of the minor allele was supported when investigating a Dutch longitudinal cohort (N=563) of oldest-old (age 85+). Since rs2069827 was located in a putative transcription factor binding site, quantitative RNA expression studies were conducted. However, no difference in IL6 expression was observed between rs2069827 genotype groups. In conclusion, we here support and expand the evidence suggesting that genetic variation in APOE, CETP, and IL6, and possible HSPA14, is associated with human longevity.

  4. Environmental stressors and cardio-metabolic disease: part I-epidemiologic evidence supporting a role for noise and air pollution and effects of mitigation strategies. (United States)

    Münzel, Thomas; Sørensen, Mette; Gori, Tommaso; Schmidt, Frank P; Rao, Xiaoquan; Brook, Jeffrey; Chen, Lung Chi; Brook, Robert D; Rajagopalan, Sanjay


    Traffic noise and air pollution together represent the two most important environmental risk factors in urbanized societies. The first of this two-part review discusses the epidemiologic evidence in support of the existence of an association between these risk factors with cardiovascular and metabolic disease. While independent effects of these risk factors have now clearly been shown, recent studies also suggest that the two exposures may interact with each other and with traditional risk factors such as hypertension and type 2 diabetes. From a societal and policy perspective, the health effects of both air pollution and traffic noise are observed for exposures well below the thresholds currently accepted as being safe. Current gaps in knowledge, effects of intervention and their impact on cardiovascular disease, will be discussed in the last section of this review. Increased awareness of the societal burden posed by these novel risk factors and acknowledgement in traditional risk factor guidelines may intensify the efforts required for effective legislation to reduce air pollution and noise.

  5. System Administration Support/SWORDS G2 (United States)

    Dito, Scott Joseph


    The Soldier-Warfighter Operationally Responsive Deployer for Space (SWORDS) rocket is a dedicated small satellite launcher that will minimize danger and complexity in order to allow soldiers in the field to put payloads of up to 25kg into orbit from the field. The SWORDSG2 project is the development of a model, simulation, and ultimately a working application that will control and monitor the cryogenic fluid delivery to the SWORDS rocket for testing purposes. To accomplish this, the project is using the programming language environment Gensym G2. The environment is an all-inclusive application that allows development, testing, modeling, and finally operation of the unique application through graphical and programmatic methods. In addition, observation of the current cryogenic fluid delivery system in the Kennedy Space Center Cry Lab has allowed me to gain valuable experience of fluid systems and propelant delivery that is valuable to our team when developing amd modeling our own system.The ultimate goal of having a test-ready application to show to the heads of the project, and demonstrating G2's capabilities, by late 2014 will require hard work and intense study and understanding of not only the programming aspect but also the physical phenomena we want to model, observe, and control.

  8. A pragmatic study exploring the prevention of delirium among hospitalized older hip fracture patients: Applying evidence to routine clinical practice using clinical decision support

    Directory of Open Access Journals (Sweden)

    Schmaltz Heidi N


    Full Text Available Abstract Delirium occurs in up to 65% of older hip fracture patients. Developing delirium in hospital has been associated with a variety of adverse outcomes. Trials have shown that multi-component preventive interventions can lower delirium rates. The objective of this study was to implement and evaluate the effectiveness of an evidence-based electronic care pathway, which incorporates multi-component delirium strategies, among older hip fracture patients. We conducted a pragmatic study using an interrupted time series design in order to evaluate the use and impact of the intervention. The target population was all consenting patients aged 65 years or older admitted with an acute hip fracture to the orthopedic units at two Calgary, Alberta hospitals. The primary outcome was delirium rates. Secondary outcomes included length of hospital stay, in-hospital falls, in-hospital mortality, new discharges to long-term care, and readmissions. A Durbin Watson test was conducted to test for serial correlation and, because no correlation was found, Chi-square statistics, Wilcoxon test and logistic regression analyses were conducted as appropriate. At study completion, focus groups were conducted at each hospital to explore issues around the use of the order set. During the 40-week study period, 134 patients were enrolled. The intervention had no effect on the overall delirium rate (33% pre versus 31% post; p = 0.84. However, there was a significant interaction between study phase and hospital (p = 0.03. Although one hospital did not experience a decline in delirium rate, the delirium rate at the other hospital declined from 42% to 19% (p = 0.08. This difference by hospital was mirrored in focus group feedback. The hospital that experienced a decline in delirium rates was more supportive of the intervention. Overall, post-intervention there were no significant differences in mean length of stay (12 days post versus 14 days pre; p = 0.74, falls (6% post

  11. SUPPORT Tools for evidence-informed health Policymaking (STP) 10: Taking equity into consideration when assessing the findings of a systematic review. (United States)

    Oxman, Andrew D; Lavis, John N; Lewin, Simon; Fretheim, Atle


    This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. In this article we address considerations of equity. Inequities can be defined as "differences in health which are not only unnecessary and avoidable but, in addition, are considered unfair and unjust". These have been well documented in relation to social and economic factors. Policies or programmes that are effective can improve the overall health of a population. However, the impact of such policies and programmes on inequities may vary: they may have no impact on inequities, they may reduce inequities, or they may exacerbate them, regardless of their overall effects on population health. We suggest four questions that can be considered when using research evidence to inform considerations of the potential impact a policy or programme option is likely to have on disadvantaged groups, and on equity in a specific setting. These are: 1. Which groups or settings are likely to be disadvantaged in relation to the option being considered? 2. Are there plausible reasons for anticipating differences in the relative effectiveness of the option for disadvantaged groups or settings? 3. Are there likely to be different baseline conditions across groups or settings such that that the absolute effectiveness of the option would be different, and the problem more or less important, for disadvantaged groups or settings? 4. Are there important considerations that should be made when implementing the option in order to ensure that inequities are reduced, if possible, and that they are not increased?

  12. Demographic and Indication-Specific Characteristics Have Limited Association With Social Network Engagement: Evidence From 24,954 Members of Four Health Care Support Groups (United States)


    Background Digital health social networks (DHSNs) are widespread, and the consensus is that they contribute to wellness by offering social support and knowledge sharing. The success of a DHSN is based on the number of participants and their consistent creation of externalities through the generation of new content. To promote network growth, it would be helpful to identify characteristics of superusers or actors who create value by generating positive network externalities. Objective The aim of the study was to investigate the feasibility of developing predictive models that identify potential superusers in real time. This study examined associations between posting behavior, 4 demographic variables, and 20 indication-specific variables. Methods Data were extracted from the custom structured query language (SQL) databases of 4 digital health behavior change interventions with DHSNs. Of these, 2 were designed to assist in the treatment of addictions (problem drinking and smoking cessation), and 2 for mental health (depressive disorder, panic disorder). To analyze posting behavior, 10 models were developed, and negative binomial regressions were conducted to examine associations between number of posts, and demographic and indication-specific variables. Results The DHSNs varied in number of days active (3658-5210), number of registrants (5049-52,396), number of actors (1085-8452), and number of posts (16,231-521,997). In the sample, all 10 models had low R2 values (.013-.086) with limited statistically significant demographic and indication-specific variables. Conclusions Very few variables were associated with social network engagement. Although some variables were statistically significant, they did not appear to be practically significant. Based on the large number of study participants, variation in DHSN theme, and extensive time-period, we did not find strong evidence that demographic characteristics or indication severity sufficiently explain the variability in

  13. The importance of evidence-based supportive care practice guidelines in childhood cancer-a plea for their development and implementation. (United States)

    Loeffen, E A H; Kremer, L C M; Mulder, R L; Font-Gonzalez, A; Dupuis, L L; Sung, L; Robinson, P D; van de Wetering, M D; Tissing, W J E


    As cure rates in pediatric oncology have improved substantially over the last decades, supportive care has become increasingly important to reduce morbidity and mortality and improve quality of life in children with cancer. Currently, large variations exist in pediatric oncology supportive care practice, which might negatively influence care. This plea underlines the importance of development and implementation of trustworthy supportive care clinical practice guidelines, which we believe is the essential next step towards better supportive care practice, and thus a higher quality of care. To facilitate international development and endorsement, the International Pediatric Oncology Guidelines in Supportive Care Network has been established.

  14. Telecommunications administration standard

    Energy Technology Data Exchange (ETDEWEB)

    Gustwiller, K.D. [GTE Customer Networks, Albuquerque, NM (United States)


    The administration of telecommunications is critical to proper maintenance and operation. The intent is to be able to properly support telecommunications for the distribution of all information within a building/campus. This standard will provide a uniform administration scheme that is independent of applications, and will establish guidelines for owners, installers, designers and contractors. This standard will accommodate existing building wiring, new building wiring and outside plant wiring. Existing buildings may not readily adapt to all applications of this standard, but the requirement for telecommunications administration is applicable to all buildings. Administration of the telecommunications infrastructure includes documentation (labels, records, drawings, reports, and work orders) of cables, termination hardware, patching and cross-connect facilities, telecommunications rooms, and other telecommunications spaces (conduits, grounding, and cable pathways are documented by Facilities Engineering). The investment in properly documenting telecommunications is a worthwhile effort. It is necessary to adhere to these standards to ensure quality and efficiency for the operation and maintenance of the telecommunications infrastructure for Sandia National Laboratories.

    In view of uncertainty, complexity and diversity in the fault characteristics of the wind power unit's gearbox, a method of feature weight fusion based on evidence support matrix is proposed to construct the model. Two factors, the conflict coefficient and evidence distance, are analyzed, which affect the evidence conflict. An evidence support matrix is constructed. The char- acteristic vector related to the maximum eigenvalue of the matrix is calculated as an evidence weight. The evidence weights are fused using the evidence combination formula. The method is applied to fault diagnosis of a wind turbine gearbox. The results show that the proposed method can enhance efficiency and accuracy of the fault diagnosis of wind turbine gearbox.%针对风电机组齿轮箱故障特征的不确定性、复杂性和多元性的特点,提出基于证据支持矩阵特征权重的融合新方法,建立故障诊断模型。分析了影响证据冲突的冲突因子和证据距离,利用这两个因子构造证据支持度矩阵;求解了该证据支持度矩阵最大特征值对应的特征向量,并将此作为证据的权重,利用证据组合公式进行融合;最后将其用于风电机组齿轮箱故障诊断。实验结果表明,该方法可较好提高风电机组齿轮箱故障诊断的效率和准确率。

  20. Administrative Supervisors: A Qualitative Exploration of Their Perceived Role. (United States)

    Weaver, Susan H; Lindgren, Teri


    The administrative supervisor, who is the nurse manager present on the night and weekend shifts, can be found in hospitals throughout the United States. Yet, very little research has been published about this role on weekend and night shifts in acute care hospitals. The objective of this qualitative research study was to gain a better understanding of the administrative supervisor role. In-depth interviews with administrative supervisors were conducted at acute care hospitals in the mid-Atlantic region of the United States. Thematic analysis was used to reduce the data and identify codes and themes. Administrative supervisors experience and described their role within a "different" hospital world on weekends and at night. The administrative supervisors consistently stated that they oversee and are responsible for staffing and patient flow, crisis management, and management support for the staff. That administrative supervision is a challenging position for nurses is particularly evident as researchers seek to obtain a better understanding of how nurse leaders make a difference. This research delineates these different supervisor role responsibilities to provide a better understanding of management during the "off-shift." Nurse leaders can utilize this information to assist in justifying the need for this shift management role at their institutions.

  7. Do Native American Culture, Life Experiences, Physics and the Bible Provide Supportive Evidence For Julian Barbour's Thesis About Anachronisms Relating to The End of Time? (United States)

    Mears, Paul C.; Mc Leod, Roger D.


    Historic, and current Native American attitude considers that time can be considered in a cyclic sense that contrasts against a majority view of physicists that time varies in a linear algebraic sense. Precognition experiences offer evidence that time has a more subtle substance. The Bible clearly delineates "prophetic awareness of the future." Embedded "Bible codes" are touted as mathematical evidence for the existence of God. His existence is better served if "past-tense" information of events can propagate backward relative to our "present-tense" time. Barbour, p39: [some] " physicists entertain the idea time truly does not exist applies to motion .suggestion; it too is pure illusion." The concept of prophecy has been interpreted as evidence or "proof" of the existence of "Manitou" or God. Our interpretation is that, according to Native American legends, or the Bible, for as yet unspecified reasons, time behaves as though it can convey information in a backward, or forward, sense. It is like an f (t ± ti).

  12. Genetic influence on the expression of hand preferences in chimpanzees (Pan troglodytes): evidence in support of the right-shift theory and developmental instability. (United States)

    Hopkins, W D; Dahl, J F; Pilcher, D


    Genetic mechanisms have been proposed to explain the pervasive representation of right-handedness in humans, whereas random, nongenetic factors have been posited to explain the lack of population-level right-handedness in nonhuman primates. We report evidence that hand preferences in chimpanzees are heritable, even among related individuals raised in different environments. Furthermore, we report that the degree of heritability is modified by factors associated with developmental instability, notably, offspring parity. The data are interpreted to reconcile both genetic models for handedness and hypotheses suggesting that developmental instability influences variation in handedness.

  16. Supporting oral feeding in fragile infants: an evidence-based method for quality bottle-feedings of preterm, ill, and fragile infants. (United States)

    Ross, Erin Sundseth; Philbin, M Kathleen


    Successful oral feeding of preterm and other ill and fragile infants is an interactive process that requires (1) sensitive, ongoing assessment of an infant's physiology and behavior, (2) knowledgeable decisions that support immediate and long-term enjoyment of food, and (3) competent skill in feeding. Caregivers can support feeding success by using the infant's biological and behavioral channels of communication to inform their feeding decisions and actions. The Supporting Oral Feeding in Fragile Infants (SOFFI) Method is described here with text, algorithms, and reference guides. Two of the algorithms and the reference guides are published separately as Philbin, Ross. SOFFI Reference Guides: Text, Algorithms, and Appendices (in review). The information in all of these materials is drawn from sound research findings and, rarely, when such findings are not available, from expert, commonly accepted clinical practice. If the quality of a feeding takes priority over the quantity ingested, feeding skill develops pleasurably and at the infant's own pace. Once physiologic organization and behavioral skills are established, an affinity for feeding and the ingestion of sufficient quantity occur naturally, often rapidly, and at approximately the same postmenstrual age as volume-focused feedings. Nurses, therapists, and parents alike can use the SOFFI Method to increase the likelihood of feeding success in the population of infants at risk for feeding problems that emerge in infancy and extend into the preschool years.

    We leverage non-linearities in Danish child support guidelines together with rich administrative data to provide causal estimates of parental behavioral responses to child support obligations. We estimate that among families with formal child support agreements, a 1, 000 DKK ($183) increase...... find that larger obligations are associated with higher new-partner fertility among both parents. The maternal fertility response is consistent with a positive income-fertility relationship, while the paternal fertility response may reflect increased demand for new offspring as a result of reduced...... contact with existing children. Finally, we find evidence that some fathers reduce their labor supply to avoid facing higher support obligations. Our findings suggest that government efforts to increase child investments through mandates on parents can be complicated by their behavioral responses to them....

  19. Identifying community healthcare supports for the elderly and the factors affecting their aging care model preference: evidence from three districts of Beijing

    Directory of Open Access Journals (Sweden)

    Tianyang Liu


    Full Text Available Abstract Background The Chinese tradition of filial piety, which prioritized family-based care for the elderly, is transitioning and elders can no longer necessarily rely on their children. The purpose of this study was to identify community support for the elderly, and analyze the factors that affect which model of old-age care elderly people dwelling in communities prefer. Methods We used the database “Health and Social Support of Elderly Population in Community”. Questionnaires were issued in 2013, covering 3 districts in Beijing. A group of 1036 people over 60 years in age were included in the study. The respondents’ profile variables were organized in Andersen’s Model and community healthcare resource factors were added. A multinomial logistic model was applied to analyze the factors associated with the desired aging care models. Results Cohabiting with children and relying on care from family was still the primary desired aging care model for seniors (78 %, followed by living in institutions (14.8 % and living at home independently while relying on community resources (7.2 %. The regression result indicated that predisposing, enabling and community factors were significantly associated with the aging care model preference. Specifically, compared with those who preferred to cohabit with children, those having higher education, fewer available family and friend helpers, and shorter distance to healthcare center were more likely to prefer to live independently and rely on community support. And compared with choosing to live in institutions, those having fewer available family and friend helpers and those living alone were more likely to prefer to live independently and rely on community. Need factors (health and disability condition were not significantly associated with desired aging care models, indicating that desired aging care models were passive choices resulted from the balancing of family and social caring resources

  20. The multidimensional assessment of perfectionistic automatic thoughts: a commentary on "Examining mutual suppression effects in the assessment of perfectionism cognitions: evidence supporting multidimensional assessment". (United States)

    Flett, Gordon L; Hewitt, Paul L


    In the current article, we comment on a recent article by Stoeber, Kobori, and Brown that provided evidence suggesting that a multidimensional approach to perfectionistic cognitions is superior to a unidimensional approach in predicting maladjustment. They also showed with their data from a university student sample that our Perfectionism Cognitions Inventory has multiple factors in contrast to our unidimensional approach. Our commentary focuses primarily on the issue of whether the Perfectionism Cognitions Inventory should be considered unidimensional versus multidimensional and outlines concerns about how perfectionism cognition factors should be used and interpreted. Although there are serious interpretive problems inherent in existing multidimensional measures of perfectionism cognitions, it is apparent that a cognitive approach is an important and viable supplement to the extensive focus on the trait multidimensional perfectionism that is currently in vogue. We conclude by discussing the potential clinical uses of cognitive assessments of perfectionism.

  1. Experimental evidence supporting the insensitivity of cloud droplet formation to the mass accommodation coefficient for condensation of water vapor to liquid water (United States)

    Langridge, Justin M.; Richardson, Mathews S.; Lack, Daniel A.; Murphy, Daniel M.


    The mass accommodation coefficient for uptake of water vapor to liquid water, αM, has been constrained using photoacoustic measurements of aqueous absorbing aerosol. Measurements performed over a range of relative humidities and pressures were compared to detailed model calculations treating coupled heat and mass transfer occurring during photoacoustic laser heating cycles. The strengths and weaknesses of this technique are very different to those for droplet growth/evaporation experiments that have typically been applied to these measurements, making this a useful complement to existing studies. Our measurements provide robust evidence that αM is greater than 0.1 for all humidities tested and greater than 0.3 for data obtained at relative humidities greater than 88% where the aerosol surface was most like pure water. These values of αM are above the threshold at which kinetic limitations are expected to impact the activation and growth of aerosol particles in warm cloud formation.

  2. Insights in public health: Building support for an evidence-based teen pregnancy and sexually transmitted infection prevention program adapted for foster youth. (United States)

    Smith, Tamara; Clark, Judith F; Nigg, Claudio R


    Hawai'i Youth Services Network (HYSN) was founded in 1980 and is incorporated as a 501(c) (3) organization. HYSN plays a key role in the planning, creation, and funding of local youth services. One of HYSN's focuses is teen pregnancy and sexually transmitted infections (STI) prevention among foster youth. Foster youth are at a greater risk for teen pregnancy and STI due to a variety of complex factors including instability, trauma, and emancipation from the foster care system. This article highlights how HYSN is leveraging both federal and local funding, as well as other resources, in order to implement an evidence-based teen pregnancy and STI prevention program adapted for foster youth.

  3. Does Sufficient Evidence Exist to Support a Causal Association between Vitamin D Status and Cardiovascular Disease Risk? An Assessment Using Hill’s Criteria for Causality

    Directory of Open Access Journals (Sweden)

    Patricia G. Weyland


    Full Text Available Serum 25-hydroxyvitamin D (25(OHD levels have been found to be inversely associated with both prevalent and incident cardiovascular disease (CVD risk factors; dyslipidemia, hypertension and diabetes mellitus. This review looks for evidence of a causal association between low 25(OHD levels and increased CVD risk. We evaluated journal articles in light of Hill’s criteria for causality in a biological system. The results of our assessment are as follows. Strength of association: many randomized controlled trials (RCTs, prospective and cross-sectional studies found statistically significant inverse associations between 25(OHD levels and CVD risk factors. Consistency of observed association: most studies found statistically significant inverse associations between 25(OHD levels and CVD risk factors in various populations, locations and circumstances. Temporality of association: many RCTs and prospective studies found statistically significant inverse associations between 25(OHD levels and CVD risk factors. Biological gradient (dose-response curve: most studies assessing 25(OHD levels and CVD risk found an inverse association exhibiting a linear biological gradient. Plausibility of biology: several plausible cellular-level causative mechanisms and biological pathways may lead from a low 25(OHD level to increased risk for CVD with mediators, such as dyslipidemia, hypertension and diabetes mellitus. Experimental evidence: some well-designed RCTs found increased CVD risk factors with decreasing 25(OHD levels. Analogy: the association between serum 25(OHD levels and CVD risk is analogous to that between 25(OHD levels and the risk of overall cancer, periodontal disease, multiple sclerosis and breast cancer. Conclusion: all relevant Hill criteria for a causal association in a biological system are satisfied to indicate a low 25(OHD level as a CVD risk factor.

  6. XPS evidence for structure-performance relationship in selective hydrogenation of crotonaldehyde to crotyl alcohol on platinum systems supported on natural phosphates. (United States)

    Hidalgo-Carrillo, Jesús; Sebti, Jalila; Marinas, Alberto; Marinas, José M; Sebti, Said; Urbano, Francisco J


    Natural phosphates are an important natural resource in Morocco, which needs to be valorised. They can be used not only as fertilisers but also as catalysts. Here, we report for the first time on its use as support for platinum and the application of the resulting systems to the liquid-phase selective hydrogenation of an α,β-unsaturated carbonyl compound (crotonaldehyde) to the corresponding unsaturated alcohol (crotyl alcohol), a process of interest in the production of pharmaceuticals, agrochemicals and fragrances. Catalytic results are related to the surface solid structure as determined by XPS. Therefore, the most active systems showed new surface interactions as evidenced by the appearance of new P, O, Ca, F and C peaks and the shift of Pt ones to lower binding energies. Further modification of the most active system with FeCl(2) led to 70% selectivity to crotyl alcohol at 34% conversion.

  7. Molecular and morphological evidence supports the species status of the Mahachai fighter Betta sp. Mahachai and reveals new species of Betta from Thailand. (United States)

    Sriwattanarothai, N; Steinke, D; Ruenwongsa, P; Hanner, R; Panijpan, B


    Two regions of mitochondrial (mt) DNA, cytochrome c oxidase subunit 1 (COI) and 16S rRNA, were sequenced in nine species of Betta from Thailand and Indonesia. Most species showed little intraspecific COI variation (adjusted mean = 0.48%) including the putative species Betta sp. Mahachai, but one species (Betta smaragdina) included three lineages showing much greater divergence (7.03-13.48%) that probably represent overlooked species. These findings were confirmed by maximum likelihood analysis and Bayesian inference, which revealed well-supported corresponding monophyletic clades. Based on these results and morphological differences, the putative species Betta sp. Mahachai from central Thailand is a species distinct from other members of the B. splendens group and represents a new and hitherto undescribed species. Furthermore, this study also demonstrated the probable existence of two overlooked Betta species found in the Khorat plateau basin, illustrating the utility of mitochondrial genetic markers in the revelation of overlooked diversity.

  8. Positive Criminology and Rethinking the Response to Adolescent Addiction: Evidence on the Role of Social Support, Religiosity, and Service to Others (United States)

    Johnson, Byron R.; Lee, Matthew T.; Pagano, Maria E.; Post, Stephen G.


    Adolescent addiction has emerged as a major public health problem. The greatest increase in alcohol and other drug use disorders can be found among youth. Concurrently, technological advances in policing coupled with aggressive prosecuting and sentencing practices have contributed to the growth of America’s correctional system. The assertive response of policing, courts, and corrections, however, have not prevented the dramatic rise of adolescent addiction. Unfortunately, there is no national data tracking addicted youth in the criminal justice system to evaluate what works when it comes to youth with addiction. This article reviews justice system responses to adolescent offenders with addiction, and promising approaches engaging juveniles in programmatic components of Alcoholics Anonymous (AA). This study highlights the role of spirituality, service to others, and social support in maintaining sobriety, reducing arrests, and lowering recidivism for adolescents court-referred to treatment.

    Higashi, Takahiro; Nakamura, Fumiaki; Shibata, Akiko; Emori, Yoshiko; Nishimoto, Hiroshi


    Monitoring the current status of cancer care is essential for effective cancer control and high-quality cancer care. To address the information needs of patients and physicians in Japan, hospital-based cancer registries are operated in 397 hospitals designated as cancer care hospitals by the national government. These hospitals collect information on all cancer cases encountered in each hospital according to precisely defined coding rules. The Center for Cancer Control and Information Services at the National Cancer Center supports the management of the hospital-based cancer registry by providing training for tumor registrars and by developing and maintaining the standard software and continuing communication, which includes mailing lists, a customizable web site and site visits. Data from the cancer care hospitals are submitted annually to the Center, compiled, and distributed as the National Cancer Statistics Report. The report reveals the national profiles of patient characteristics, route to discovery, stage distribution, and first-course treatments of the five major cancers in Japan. A system designed to follow up on patient survival will soon be established. Findings from the analyses will reveal characteristics of designated cancer care hospitals nationwide and will show how characteristics of patients with cancer in Japan differ from those of patients with cancer in other countries. The database will provide an infrastructure for future clinical and health services research and will support quality measurement and improvement of cancer care. Researchers and policy-makers in Japan are encouraged to take advantage of this powerful tool to enhance cancer control and their clinical practice.

  10. Administrative Coordination in Non-Profit Human Service Delivery Networks: The Role of Competition and Trust. (United States)

    Bunger, Alicia C


    Non-profit human service organizations operating within the same regional network are often faced with dual pressure to compete as well as coordinate administrative operations (by sharing funding, staff or space) to enhance efficiency. Emerging evidence has demonstrated that competing organizations coordinate, despite the risks. Trust, or perceived trustworthiness between two organizations may mitigate the negative influence of competition on coordination, however there have been few explicit tests of this hypothesis among non-profit organizations. Drawing on quantitative data collected from a network of 36 non-profit children's behavioral health organizations, this paper empirically tests how competition and perceived trustworthiness interact to influence administrative coordination. Results support the hypothesis that trustworthiness moderates the influence of competition on administrative coordination. Findings suggest that as competing non-profit leaders build trust, the more their agencies coordinate their administrative functions. This study highlights the importance of leaders' perceptions for organizational strategy.

  11. Leptin levels are reduced by intravenous ghrelin administration and correlated with cue-induced alcohol craving. (United States)

    Haass-Koffler, C L; Aoun, E G; Swift, R M; de la Monte, S M; Kenna, G A; Leggio, L


    Increasing evidence supports the role of appetite-regulating pathways, including ghrelin and leptin, in alcoholism. This study tested the hypothesis that intravenous exogenous ghrelin administration acutely decreases endogenous serum leptin levels, and that changes in leptin levels negatively correlate with alcohol craving. This was a double-blind, placebo-controlled human laboratory study. Non-treatment-seeking, alcohol-dependent, heavy drinkers (n=45) were randomized to receive intravenous ghrelin or placebo, followed by a cue-reactivity procedure, during which participants were exposed to neutral (juice) and alcohol trial cues. There was a main effect for intravenous ghrelin administration, compared with placebo, in reducing serum leptin levels (Pcraving.

  13. Ultrastructural localization of extracellular matrix proteins of the lymph node cortex: evidence supporting the reticular network as a pathway for lymphocyte migration

    Directory of Open Access Journals (Sweden)

    Sobocinski Gregg P


    Full Text Available Abstract Background The lymph node (LN is a crossroads of blood and lymphatic vessels allowing circulating lymphocytes to efficiently recognize foreign molecules displayed on antigen presenting cells. Increasing evidence indicates that after crossing high endothelial venules, lymphocytes migrate within the node along the reticular network (RN, a scaffold of fibers enwrapped by fibroblastic reticular cells (FRC. Light microscopy has shown that the RN contains specific extracellular matrix (ECM proteins, which are putative molecular "footholds" for migration, and are known ligands for lymphocyte integrin adhesion receptors. Results To investigate whether ECM proteins of the RN are present on the outer surface of the FRC and are thus accessible to migrating lymphocytes, ultrastructural immunohistochemical staining of cynomolgus monkey LN was performed using antibodies to human ECM proteins that were successfully employed at the light microscopic level. The fibrillar collagens I and III were observed primarily within the reticular network fibers themselves. In contrast, the matrix proteins laminin, fibronectin, collagen IV, and tenascin were observed within the reticular fibers and also on the outer membrane surface of the FRC. Conclusions These findings suggest a molecular basis for how the RN functions as a pathway for lymphocyte migration within the lymph node.

  14. Evidence supporting a promotora-delivered entertainment education intervention for improving mothers' dietary intake: the Entre Familia: Reflejos de Salud Study. (United States)

    Entertainment education and the promotora model are 2 evidence-based health communication strategies. This study examined their combined effect on promoting healthy eating among mothers in a family-based intervention. Participants were 361 Mexican-origin families living in Imperial County, California, who were randomly assigned to an intervention or delayed treatment condition. The intervention involved promotoras (community health workers) who delivered 11 home visits and 4 telephone calls. Home visits included a 12-minute episode of a 9-part situation comedy depicting a family struggling with making healthy eating choices; an accompanying family workbook was reviewed to build skills and left with the family. Baseline and immediate postintervention data were collected from the mothers, including the primary outcome of daily servings of fruits and vegetables. Other dietary and psychosocial factors related to healthy eating were examined. At postintervention, mothers in the intervention reported increases in daily vegetable servings (p ≤ .05); however, no changes were observed in fruit consumption. Improvements were observed in behavioral strategies to increase fiber (p ≤ .001) and to decrease fat intake (p ≤ .001), unhealthy eating behaviors (p ≤ .001), and individual (p ≤ .05) and family-related (p ≤ .01) perceived barriers to healthy eating. Entertainment education and promotoras engaged families and improved mothers' diets. Further research should examine the dose needed for greater changes.

  15. Case of administrative dispute

    Directory of Open Access Journals (Sweden)

    Xhemazie Ibraimi


    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

  17. Glycogenolysis in astrocytes supports blood-borne glucose channeling not glycogen-derived lactate shuttling to neurons: evidence from mathematical modeling. (United States)

    DiNuzzo, Mauro; Mangia, Silvia; Maraviglia, Bruno; Giove, Federico


    In this article, we examined theoretically the role of human cerebral glycogen in buffering the metabolic requirement of a 360-second brain stimulation, expanding our previous modeling study of neurometabolic coupling. We found that glycogen synthesis and degradation affects the relative amount of glucose taken up by neurons versus astrocytes. Under conditions of 175:115 mmol/L (∼1.5:1) neuronal versus astrocytic activation-induced Na(+) influx ratio, ∼12% of astrocytic glycogen is mobilized. This results in the rapid increase of intracellular glucose-6-phosphate level on stimulation and nearly 40% mean decrease of glucose flow through hexokinase (HK) in astrocytes via product inhibition. The suppression of astrocytic glucose phosphorylation, in turn, favors the channeling of glucose from interstitium to nearby activated neurons, without a critical effect on the concurrent intercellular lactate trafficking. Under conditions of increased neuronal versus astrocytic activation-induced Na(+) influx ratio to 190:65 mmol/L (∼3:1), glycogen is not significantly degraded and blood glucose is primarily taken up by neurons. These results support a role for astrocytic glycogen in preserving extracellular glucose for neuronal utilization, rather than providing lactate to neurons as is commonly accepted by the current 'thinking paradigm'. This might be critical in subcellular domains during functional conditions associated with fast energetic demands.

  18. Lateral displacement of silty clay under cement-fly ash-gravel pile-supported embankments:Analytical consideration and field evidence

    Institute of Scientific and Technical Information of China (English)

    张崇磊; 蒋关鲁; 刘先峰; 王智猛


    Based on back analysis of lateral displacements measured in situ by using the analytical solution, a useful method for estimating stress concentration ratio of geosynthetic-reinforced and pile-supported (GRPS) embankments was proposed. In order to validate the proposed method, a full-scale high-speed railway embankment (HSRE) with four instrumented subsections over medium compressibility silty clay was constructed in three stages. The soil profile, construction procedure and monitoring of settlements and lateral displacements of the four test sections were described. The field deformation analysis results show that 1) the combined reinforcement of CFG piles and geosynthetic layer perform well in terms of reducing lateral displacements;2) the development of lateral displacements lags behind the increase of fill load, which can be attributed to the vertical load transfer mechanism of the pile foundation;and 3) pile length has a dominant effect on the stress distribution proportion between piles and surrounding soils. The comparison between predicted and experimental results suggests that the proposed analytical solution and the back analysis-based method are capable of reasonably estimating the lateral deformation and the stress concentration ratio, respectively, if the appropriate soil elastic modulus is chosen.

Alboglabra Baily ) was considered to be originated from Mediterranean coast or South China. In order to obtain the molecular evidence of the Chinese kale origination, EST-SSR markers were used to study the genetic diversity of Brassica oleracea. 38 samples were examined with 61 primer pairs of EST-SSR and amplified 174 fragments that were polymorphic, stable and clear. The genetic similarity coefficients were calculated by software NTSYSpc2.11 based on EST-SSR results. One detailed phylogenetic tree was generated by UPGMA clustering. All the samples were clustered into 3 groups on coefficient of 0.62, the group of Northwest Europe Coast, the group of Mediterranean Coast, and the group of South China, respectively. It suggested that Chinese kale was originated in South China. Chinese kale was clustered into 2 groups based on leaf shape and leaf surface in this study.

  2. Cigarette smoke induced genotoxicity and respiratory tract pathology: evidence to support reduced exposure time and animal numbers in tobacco product testing. (United States)

    Dalrymple, Annette; Ordoñez, Patricia; Thorne, David; Walker, David; Camacho, Oscar M; Büttner, Ansgar; Dillon, Debbie; Meredith, Clive


    Many laboratories are working to develop in vitro models that will replace in vivo tests, but occasionally there remains a regulatory expectation of some in vivo testing. Historically, cigarettes have been tested in vivo for 90 days. Recently, methods to reduce and refine animal use have been explored. This study investigated the potential of reducing animal cigarette smoke (CS) exposure to 3 or 6 weeks, and the feasibility of separate lung lobes for histopathology or the Comet assay. Rats were exposed to sham air or CS (1 or 2 h) for 3 or 6 weeks. Respiratory tissues were processed for histopathological evaluation, and Alveolar type II cells (AEC II) isolated for the Comet assay. Blood was collected for Pig-a and micronucleus quantification. Histopathological analyses demonstrated exposure effects, which were generally dependent on CS dose (1 or 2 h, 5 days/week). Comet analysis identified that DNA damage increased in AEC II following 3 or 6 weeks CS exposure, and the level at 6 weeks was higher than 3 weeks. Pig-a mutation or micronucleus levels were not increased. In conclusion, this study showed that 3 weeks of CS exposure was sufficient to observe respiratory tract pathology and DNA damage in isolated AEC II. Differences between the 3 and 6 week data imply that DNA damage in the lung is cumulative. Reducing exposure time, plus analyzing separate lung lobes for DNA damage or histopathology, supports a strategy to reduce and refine animal use in tobacco product testing and is aligned to the 3Rs (replacement, reduction and refinement).

  3. Supporting evidence from the EPICA Dronning Maud Land ice core for atmospheric CO{sub 2} changes during the past millennium

    Energy Technology Data Exchange (ETDEWEB)

    Siegenthaler, Urs; Monnin, Eric; Kawamura, Kenji; Spahni, Renato; Schwander, Jakob; Stauffer, Bernhard; Stocker, Thomas F. [Univ. of Bern, (Switzerland). Climate and Environmental Physics; Barnola, Jean-Marc [CNRS Laboratoire de Glaciologie et de Geophysique de l' Environnement (LGGE), Grenoble (France); Fischer, Hubertus [Alfred Wegener Inst. fuer Polar- und Meeresforschung, Bremerhaven (Germany)


    The most direct method of investigating past variations of the atmospheric CO{sub 2} concentration before 1958, when continuous direct atmospheric CO{sub 2} measurements started, is the analysis of air extracted from suitable ice cores. Here we present a new detailed CO{sub 2} record from the Dronning Maud Land (DML) ice core, drilled in the framework of the European Project for Ice Coring in Antarctica (EPICA) and some new measurements on a previously drilled ice core from the South Pole. The DML CO{sub 2} record shows an increase from about 278 to 282 parts per million by volume (ppmv) between ad 1000 and ad 1200 and a fairly continuous decrease to a mean value of about 277 ppmv around ad 1700. While the new South Pole measurements agree well with DML at the minimum at ad 1700 they are on average about 2 ppmv lower during the period ad 1000-1500. Published measurements from the coastal high-accumulation site Law Dome are considered as very reliable because of the reproducibility of the measurements, high temporal resolution and an accurate time scale. Other Antarctic ice cores could not, or only partly, reproduce the pre-industrial measurements from Law Dome. A comparison of the trends of DML and Law Dome shows a general agreement. However we should be able to rule out co-variations caused by the same artefact. Two possible effects are discussed, first production of CO{sub 2} by chemical reactions and second diffusion of dissolved air through the ice matrix into the bubbles. While the first effect cannot be totally excluded, comparison of the Law Dome and DML record shows that dissolved air diffusing to bubbles cannot be responsible for the pre-industrial variation. Therefore, the new record is not a proof of the Law Dome results but the first very strong support from an ice core of the Antarctic plateau.

  6. Local antimicrobial administration for prophylaxis of surgical site infections. (United States)

    Huiras, Paul; Logan, Jill K; Papadopoulos, Stella; Whitney, Dana


    Despite a lack of consensus guidelines, local antibiotic administration for prophylaxis of surgical site infections is used during many surgical procedures. The rationale behind this practice is to provide high antibiotic concentrations at the site of surgery while minimizing systemic exposure and adverse effects. Local antibiotic administration for surgical site prophylaxis has inherent limitations in that antibiotics are applied after the incision is made, rather than the current standard for surgical site prophylaxis that recommends providing adequate antibiotic concentrations at the site before the incision. The efficacy and safety of local application of antibiotics for surgical site prophylaxis have been assessed in different types of surgery with a variety of antibiotic agents and methods of application. We identified 22 prospective, randomized, controlled trials that evaluated local application of antibiotics for surgical site prophylaxis. These trials were subsequently divided and analyzed based on the type of surgical procedure: dermatologic, orthopedic, abdominal, colorectal, and cardiothoracic. Methods of local application analyzed included irrigations, powders, ointments, pastes, beads, sponges, and fleeces. Overall, there is a significant lack of level I evidence supporting this practice for any of the surgical genres evaluated. In addition, the literature spans several decades, and changes in surgical procedures, systemic antibiotic prophylaxis, and microbial flora make conclusions difficult to determine. Based on available data, the efficacy of local antibiotic administration for the prophylaxis of surgical site infections remains uncertain, and recommendations supporting this practice for surgical site prophylaxis cannot be made.

In particular, the author examines administrative jurisdiction before 1918, when Poland regained its independence, the period of the Duchy of Warsaw, the Kingdom of Poland, and the practice on Polish territory under Austrian and Prussian control. The author then moves to modern law by presenting the judicial system in Poland in general, especially the differences between the separate systems of general courts and administrative courts, and analyses the jurisdiction of voivodship (regional administrative courts, and the basic principles of judicial and administrative proceedings. The focus of study is mainly devoted to judicial and administrative procedure, rather than an administrative process of citizens before administrative authorities regulated in a separate Code of Administrative Procedure. The article describes the role of the judge (pointing out the differences between the active role of first instance judges and the limited capabilities of the judges of the appeal and the powers of the Supreme Court, in particular its power to adopt resolutions, which has agreat importance for the unification of the jurisprudence. A brief analysis is given to class actions, which in the Polish legal system are inadmissible in court and administrative proceedings. The articles provides a statistical cross-section illustrating the role of administrative jurisdiction. The author concludes with observations pointing up the progress of administrative jurisdiction in Poland, not only in the legal sense, but also in the cultural sense.

  10. Reviewing Illness Self-Management Programs: A Selection Guide for Consumers, Practitioners, and Administrators. (United States)

    Petros, Ryan; Solomon, Phyllis


    Illness self-management (ISM) programs for adults with serious mental illness offer strategies to increase self-directed recovery activities to maximize wellness and increase independence from the service delivery system. This article describes five of the most popular ISM programs: Pathways to Recovery, The Recovery Workbook, Building Recovery of Individual Dreams and Goals through Education and Support, Wellness and Recovery Action Planning, and Illness Management and Recovery. It provides guidance for administrators, practitioners, and consumers for the purposes of selecting the program or programs providing the best fit. The framework for describing the five programs encompasses four contextual domains that supplement empirical evidence for a more comprehensive evaluation: structure, value orientation toward recovery, methods of teaching, and educational content. Contextual domains distinguish programs from one another, including length and time commitment, requisite resources, inclusion of group support, utilization of medical language and pathology, degree of traditional didactic education, and prioritization of consumer-driven self-exploration. The authors also searched PsycINFO, Google Scholar, and Cochrane Reviews for empirical evidence and evaluated the five programs on the strength of the evidence and the effectiveness of the intervention. Evidence of program effectiveness was found to range from low to moderate. However, empirical evidence alone is insufficient for selecting among the five programs, and contextual domains may offer the most relevant guidance by matching program features with goals of consumers, practitioners, and administrators.

  18. On the use of administrative databases to support planning activities: the case of the evaluation of neonatal case-mix in the Emilia-Romagna region using DRG and APR-DRG classification systems. (United States)

    Fantini, M P; Cisbani, L; Manzoli, L; Vertrees, J; Lorenzoni, L


    There are several versions of the Diagnosis Related Group (DRG) classification systems that are used for case-mix analysis, utilization review, prospective payment, and planning applications. The objective of this study was to assess the adequacy of two of these DRG systems--Medicare DRG and All Patient Refined DRG--to classify neonatal patients. The first part of the paper contains a descriptive analysis that outlines the major differences between the two systems in terms of classification logic and variables used in the assignment process. The second part examines the statistical performance of each system on the basis of the administrative data collected in all public hospitals of the Emilia-Romagna region relating to neonates discharged in 1997 and 1998. The Medicare DRG are less developed in terms of classification structure and yield a poorer statistical performance in terms of reduction in variance for length of stay. This is important because, for specific areas, a more refined system can prove useful at regional level to remove systematic biases in the measurement of case-mix due to the structural characteristics of the Medicare DRGs classification system.

    Directory of Open Access Journals (Sweden)

    Vasilica Negruț


    Full Text Available The Constitution of Romania revised in 2003 establishes the free and voluntary nature of the special administrative jurisdictions, a fact which allows the party concerned to address either the administrative-judicial body or directly the court. If they opted for the administrative-judicial way, it must be followed to the end, then, under the terms established by the law, the party may address the court, under the right of access to justice provided by article 21 of the constitution. The administrative jurisdiction is an activity of solving an administrative litigation by specific procedural rules of judicial procedure, based on the principle of the independence, of insuring the right to defense and the administrative-jurisdictional independence activity, which results in a jurisdictional administrative act. In order to achieve the objectives of the paper, namely to highlight the essential elements of the resolution of litigation according to special administrative jurisdictions, we have achieved an analysis of the legislative acts referring to this activity, of the doctrine and jurisprudence. After examination and empirical research, the paper summarizes and specifies the general conclusions on the role and importance of special administrative courts.

Bis selenide (0.5-5 mg/kg, p.o.) decreased the immobility time in the mouse FST and TST. The anti-immobility effect of bis selenide (1 mg/kg, p.o.) in the TST was prevented by the pretreatment of mice with p-chlorophenylalanine methyl ester (PCPA; 100 mg/kg, i.p., an inhibitor of serotonin synthesis), ketanserin (1 mg/kg, i.p., a 5-HT(2A/2C) receptor antagonist), and ondasentron (1 mg/kg, i.p., a 5-HT(3) receptor antagonist). Pretreatment of mice with prazosin (1 mg/kg, i.p., an alpha(1)-adrenoceptor antagonist), yohimbine (1 mg/kg, i.p., an alpha(2)-adrenoceptor antagonist), propranolol (2 mg/kg, i.p., a beta-adrenoceptor antagonist), SCH23390 (0.05 mg/kg, s.c., a dopamine D(1) receptor antagonist), sulpiride (50 mg/kg, i.p., a dopamine D(2) receptor antagonist), or WAY 100635 (0.1 mg/kg, s.c., a selective 5-HT(1A) receptor antagonist) did not block the antidepressant-like effect of bis selenide (1 mg/kg, p.o.) in the TST. Administration of bis selenide (0.1 mg/kg, p.o.) and fluoxetine (1 mg/kg), at subeffective doses, produced an antidepressant-like effect in the TST. Bis selenide did not alter Na(+) K(+) ATPase, MAO-A and MAO-B activities in whole brains of mice. Bis selenide produced an antidepressant-like effect in the mouse TST and FST, which may be related to the serotonergic system (5-HT(2A/2C) and 5-HT(3) receptors).

    Liao Zongrong Case was published on Vol.1 of Gazette of the Supreme People's Court in 2007, which has drawn great attention due to the preponderant evidence standard used by the court. This paper tries to synthesize the elements of preponderant evidence when exploited in administrative lawsuits by analyzing the case. In addition, this paper attempts to ifnd the prerequisites of applying the preponderant evidence in administrative lawsuits through the comparison of several similar court decisions. It shows that the preponderant evidence standard constitutes of three elements, which are identity element, authenticity element and relationship element. Moreover, this standard could only be applied under the circumstances of one-by-one evidence.%《最高人民法院公报》2007年第1期刊载的“廖宗荣诉重庆市公安局交通管理局第二支队道路交通管理行政处罚决定案”运用的“优势证据”标准引起了学界的广泛关注。本文尝试以这一案例为分析样本,通过对判决主文的剖析,希冀从中提炼出“优势证据”的若干构成要件;并通过对相关案例的对比,以期发现优势证据在行政诉讼语境中的适用前提。分析显示,公报案例中的“优势证据”暗含了三个构成要件,分别为身份要件、真实要件、关系要件;而数个案例的对比分析揭示,公报案例中的“优势证据”只适用于一对一证据的情境。

  2. The US Food and Drug Administration and the Future of Cardiovascular Medicine. (United States)

    Fiuzat, Mona; Califf, Robert M


    Cardiovascular medicine has led the drive for creativity and innovation with a culture that has been at the forefront of evidence generation. However, we are functioning at only a fraction of our evidence generation capacity. Despite the leadership of cardiovascular medicine, very few guideline recommendations are supported by high levels of evidence, and the proportion of recommendations for which there is no conclusive evidence is substantial. Clinical research has proven to be too slow, unreliable, and expensive as conducted in the past. In the current era, a new model of unlimited information, better access to care, and better payer coverage has the potential to change our evidence base to support clinical guidelines. We now have the opportunity to use volumes of data to support US Food and Drug Administration labeling and practice guidelines. The electronic health record can be used to feed decisions and provide an information feedback loop. In addition, learning health systems can contribute to providing networks and registries for information sharing. In this Special Communication, we summarize opportunities of the cardiovascular community to build on its pioneering leadership in evidence-based medicine through major initiatives now under way. By joining in broad efforts to create an efficient national evidence generation system, larger proportions of clinical practice can be guided by high-quality evidence; clinicians and their practice organizations will be increasingly able to focus on interpreting, applying, and communicating research findings to improve outcomes; and patients and consumers will be increasingly informed and empowered to play active roles in managing their own health and health care.

Two arguments are made: first......, it is argued that the changes in administrative practices during the last decade constitute a transformation, but also a reproduction of relations between knowledge and governing that goes back to the big expansion of the welfare state. Second, it is argued that these relations between knowledge and governing...... are not restricted to the administrative practices, but are part of education and its humanistic legacy as well. As such, the administrative demand of documentation becomes possible and recognisable through its reproductive elements. Elements that are constituted in a transformative conjunction in which...

  16. Evidence-based librarianship: searching for the needed EBL evidence. (United States)

    Eldredge, J D


    This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).

  18. Centralized administrative services management. (United States)

    Freed, D H


    Virtually every hospital has imposed guidelines or controls on one or more administrative service expenses. However, the actual deployment of such strategies is often voluntary, decentralized, disjointed and episodic. An alternative approach is to cluster administrative elements across hospital departments and make them the responsibility of a dedicated manager. This approach treats administrative services as an organizing principle with uniform, predictable standards of service and cost. Customer requirements for products and services are met without the need for them to physically manage that process. Materiel managers can demonstrate a leadership role by applying their professionalism and know-how to a set of products and services traditionally ignored or dealt with in an uncoordinated manner. While some initial resistance can be expected as traditional barriers are disassembled, the results should be very rewarding for the hospital and materiel manager alike.

  6. Opportunities for administrators to promote disease management. (United States)

    Kash, Bita A; Gamm, Larry D; Bolin, Jane Nelson; Peck, B Mitchell


    Studies of disease management (DM) have shown that patients who participate in such programs achieve better health status and make fewer emergency room visits. Private and government payers have recently increased their efforts to promote DM initiatives through financial incentives to healthcare providers. This article explores opportunities for administrators of health services organizations (HSO) to promote DM in the current political and economic environment. Our survey of professionals (DM leaders, physicians, and DM nurses) in six DM programs reveals these professionals' assessments of the key players and resources that they deem important to their respective DM programs. They view DM programs as heavily dependent on the support of physicians, nurses, and health plan leaders but relatively less so on the support of HSO administrators- a situation that may suggest opportunities for administrators to take on greater leadership in moving the HSO toward developing DM programs. Survey results also indicate a strong need for the integration of resources such as communication systems, electronic medical records, and DM reporting. Taken collectively, these needs suggest a number of strategies for the administrator to play a larger role in supporting the adoption and effective implementation of DM. In the article, we propose that DM programs can benefit substantially from an administrator who can demonstrate a thorough knowledge of DM-related government and private-payer initiatives and who has the ability to provide leadership to develop and implement viable DM programs. Valued contributions that the administrator should bring to the table include support of standardized DM processes, use of practice guidelines, and provision of pertinent information systems.

The present research aimed to search for validity evidences to Depression Scale (EDEP based on the relation to other variables assessing the same construct, depression, being also assessed by Beck Depression Inventory - BDI, and assessing related constructs, family support, measured by Perception of Family Support Inventory - IPSF. 157 undergraduates from a private university located in south state of Minas Gerais, 75,5% from female gender and 24,5% from male gender, aging from 18 to 51 years old (M=23,2; DP=6,4 took part in this study. At the results, high, significant and positive correlations were found between EDEP and BDI, as expected, indicating that the higher the scores on both scales, higher the depressive symptoms. As for the correlations between EDEP and IPSF dimensions, significant and negative correlations were found, suggesting that the higher depressive symptoms lower the perception of family support on individuals. Only marginally significant differences were found between genders, as to depressive symptoms (EDEP and BDI, indicating that women would score more at the depression scales.

In 2007, it was evident that many experiences related to libre software were running in Public Administrations with different levels of success. However, no study had looked into the details of these experiences, and no comprehensive analysis had been performed to better understand the different factors that affect them.

  10. Evidence and evidence gaps – an introduction (United States)

    Dreier, Gabriele; Löhler, Jan


    , databases, information portals with processed evidence as well as specific journals and finally teaching are appropriate vehicles. One problem is the multitude of information so that knowledge gaps may affect the clinical routine despite actually existing evidence. Generally, it still takes several years until new knowledge is implemented in daily routine. Tasks: The German Society of Oto-Rhino-Laryngology, Head and Neck Surgery (Deutsche Gesellschaft für Hals-, Nasen- und Ohren-Heilkunde, Kopf- und Hals-Chirurgie e.V., DGHNOKHC) and the Professional Association of Otolaryngologists (Deutscher Berufsverband der HNO-Ärzte e.V., BVHNO) have fundamental interest in supporting their members in generating, processing, and providing evidence as well as accompanying knowledge transfer. It encompasses the fields of diagnostics, therapy, and prognosis in the same way as prevention and applies to medicinal products as well as to medical devices or surgical procedures. The base for this is the regular assessment of evidence gaps, also in the area of established procedures, that has to be followed by a prioritization of research questions and the subsequent initiation of clinical research. In addition, large trials verifying therapies and diagnostics, for example in the context of daily conditions after approval, can only be conducted combining all resources in the ENT community. Method, results, and outlook: Together, the executive committees of the DGHNOKHC and the BVHNO founded the German Study Center of Oto-Rhino-Laryngology, Head and Neck Surgery (Deutsches Studienzentrum für Hals-, Nasen- und Ohren-Heilkunde, Kopf- und Hals-Chirurgie, DSZ-HNO). First projects have been initiated, among those a clinical trial on the therapy of sudden hearing loss supported by the BMBF and a survey on evidence gaps in oto-rhino-laryngology. It seems to be both reasonable and feasible to make available methodological expertise via such an infrastructure of a study center for physicians in

  2. [Intravesical therapy with mitomycin through electromotive drug administration]. (United States)

    Verri, Cristian; Liberati, Emanuele; Celestino, Francesco; De Carlo, Francesco; Torelli, Fiammetta; Di Stasi, Savino M


    In the management of non-muscle invasive bladder cancer (NMIBC), high-level evidence supports the widespread practice of intravesical therapy with mitomycin-C (MMC). Randomized trials showed a significant reduction in short-term recurrence compared with transurethral resection of bladder tumor (TURBT) alone, but little effect on long-term and no impact at all in preventing progression. Electromotive drug administration (EMDA®) offers a means of controlling and enhancing the tissue transport of certain drugs, in order to increase their efficacy. In both laboratory and clinical studies, intravesical electromotive drug administration (EMDA) increases MMC bladder uptake, resulting in an improved clinical efficacy in NMIBC without systemic side effects. New frameworks for treatment of NMIBC - e.g., sequential intravesical BCG and EMDA/MMC, as well as intravesical EMDA/MMC immediately before TURBT - have provided promising preliminary results with higher remission rates and longer remission times, and they are a priority to minimise the costs of disease management. These findings suggest EMDA-enhanced MMC efficacy against urothelial cancer could be a major therapeutic breakthrough in the treatment of NMIBC.

  3. Intracerebroventricular administration of kappa-agonists induces convulsions in mice. (United States)

    Bansinath, M; Ramabadran, K; Turndorf, H; Shukla, V K


    Intracerebroventricular (ICV) administration of kappa-agonists (PD 117302, U-50488H and U-69593) induced convulsions in a dose-related manner in mice. The dose at which 50% of animals convulsed (CD50) was in nmol ranges for all opioids. Among the opioids used, PD 117302 was the most potent convulsant. ICV administration of either vehicle alone or U-53445E, a non-kappa-opioid (+) enantiomer of U-50488H did not induce convulsions. The convulsive response of kappa-agonists was differentially susceptible for antagonism by naloxone and/or MR 2266. Collectively, these findings support the view that convulsions induced by kappa-agonists in mice involve stereospecific opioid receptor mechanisms. Furthermore, the convulsant effect of kappa-agonists could not be modified by pretreatment with MK-801, ketamine, muscimol or baclofen. It is concluded that kappa-opioid but not NMDA or GABA receptor mechanisms are involved in convulsions induced by kappa-agonists. These results are the first experimental evidence implicating stereospecific kappa-receptor mechanisms in opioid-induced convulsions in mice.

    Grimmelikhuijsen, Stephan; Jilke, Sebastian; Olsen, Asmus Leth;


    We propose behavioral public administration as a designated subfield in public administration which explicitly deals with the integration of theories and methods from psychology into the study of public administration. We discuss how scholars in public administration currently draw on both...... methodological and theoretical innovations in psychology and point to research questions in public administration which could benefit from further integration. Behavioral public administration cannot, and should not, replace ‘conventional’ public administration, but it is complementary to it. Importantly......, behavioral public administration represents a two-way street in which public administration scholars use theories and methods from psychology, and psychologists, in turn, learn from our setting of political-administrative contexts to refine their theories and methods. Finally, we propose four principals...

  5. Law Tackling Administrative Monopolies

    Institute of Scientific and Technical Information of China (English)



    @@ The long-anticipated anti-monopoly law needs to better address the crucial distinction between administrative and economic monopolies The first five months of 2oo6 saw a surge in the profits achieved by key State enterprises, especially in the eight sectors including petroleum, telecommunication and electricity, which achieved 285 billion yuan (US$36 billion) in profits, accounting for about 86 percent of the total, according to a July report. From the Stateowned Assets Supervision and Administration Commission of the State (SASAC). This news was both heartening and disquieting, for the most profitable sectors happen to be monopolistic enterprises, mostly upstream the production chain, who achieve their profitability at the expense of those companies further downstream. For years these sectors have been at the centre of the "bust-the-trust" storm.

    The ATLAS Trigger and Data Acquisition (TDAQ) system is responsible for the online processing of live data, streaming from the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. The online farm is composed of ̃3000 servers, processing the data readout from ̃100 million detector channels through multiple trigger levels. During the two years of the first Long Shutdown (LS1) there has been a tremendous amount of work done by the ATLAS TDAQ System Administrators, implementing numerous new software applications, upgrading the OS and the hardware, changing some design philosophies and exploiting the High Level Trigger farm with different purposes. During the data taking only critical security updates are applied and broken hardware is replaced to ensure a stable operational environment. The LS1 provided an excellent opportunity to look into new technologies and applications that would help to improve and streamline the daily tasks of not only the System Administrators, but also of the scientists who wil...

  10. Intracerebroventricular administration of drugs. (United States)

    Cook, Aaron M; Mieure, Katherine D; Owen, Robert D; Pesaturo, Adam B; Hatton, Jimmi


    Intracerebroventricular drug administration is a method that bypasses the blood-brain barrier and other mechanisms that limit drug distribution into the brain, allowing high drug concentrations to enter the central compartment. Instillation of drugs directly into the ventricles of the brain must be done carefully and with full consideration of factors affecting the efficacy and safety of this route of administration. These factors include the osmolarity, pH, volume, and presence of preservatives and diluents of the drug solution being administered. Very few studies have formally investigated intraventricular therapies, and dosing recommendations may vary widely depending on the agent and the patient. Many antimicrobials have been given intraventricularly, although very few prospective studies have evaluated this strategy. There are wide variations among the reports regarding dosage regimens and the pharmacokinetics of the antimicrobials used. Guidance on appropriate formulations and their use is lacking. Clinicians should be aware of their patients' ongoing disease processes and neurologic status, as well as pertinent physiochemical properties of drugs when formulating them for intracerebroventricular administration; a high index of suspicion should be maintained when monitoring patients for adverse drug events after instillation.

  12. Oral ondansetron administration in emergency departments to children with gastroenteritis: an economic analysis.

    Directory of Open Access Journals (Sweden)

    Stephen B Freedman


    Full Text Available BACKGROUND: The use of antiemetics for children with vomiting is one of the most controversial decisions in the treatment of gastroenteritis in developed countries. Ondansetron, a selective serotonin receptor antagonist, has been found to be effective in improving the success of oral rehydration therapy. However, North American and European clinical practice guidelines continue to recommend against its use, stating that evidence of cost savings would be required to support ondansetron administration. Thus, an economic analysis of the emergency department administration of ondansetron was conducted. The primary objective was to conduct a cost analysis of the routine administration of ondansetron in both the United States and Canada. METHODS AND FINDINGS: A cost analysis evaluated oral ondansetron administration to children presenting to emergency departments with vomiting and dehydration secondary to gastroenteritis from a societal and health care payer's perspective in both the US and Canada. A decision tree was developed that incorporated the frequency of vomiting, intravenous insertion, hospitalization, and emergency department revisits. Estimates of the monetary costs associated with ondansetron use, intravenous rehydration, and hospitalization were derived from administrative databases or emergency department use. The economic burden in children administered ondansetron plus oral rehydration therapy was compared to those not administered ondansetron employing deterministic and probabilistic simulations. We estimated the costs or savings to society and health care payers associated with the routine administration of ondansetron. Sensitivity analyses considered variations in costs, treatment effects, and exchange rates. In the US the administration of ondansetron to eligible children would prevent approximately 29,246 intravenous insertions and 7,220 hospitalizations annually. At the current average wholesale price, its routine administration

  1. Current concepts on hemodynamic support and therapy in septic shock

    Directory of Open Access Journals (Sweden)

    Leonardo Lima Rocha


    Full Text Available ABSTRACTSevere sepsis and septic shock represent a major healthcare challenge. Much of the improvement in mortality associated with septic shock is related to early recognition combined with timely fluid resuscitation and adequate antibiotics administration. The main goals of septic shock resuscitation include intravascular replenishment, maintenance of adequate perfusion pressure and oxygen delivery to tissues. To achieve those goals, fluid responsiveness evaluation and complementary interventions - i.e. vasopressors, inotropes and blood transfusion - may be necessary. This article is a literature review of the available evidence on the initial hemodynamic support of the septic shock patients presenting to the emergency room or to the intensive care unit and the main interventions available to reach those targets, focusing on fluid and vasopressor therapy, blood transfusion and inotrope administration.

  4. Stakeholder Meeting: Integrated Knowledge Translation Approach to Address the Caregiver Support Gap. (United States)

    Holroyd-Leduc, Jayna M; McMillan, Jacqueline; Jette, Nathalie; Brémault-Phillips, Suzette C; Duggleby, Wendy; Hanson, Heather M; Parmar, Jasneet


    Family caregivers are an integral and increasingly overburdened part of the health care system. There is a gap between what research evidence shows is beneficial to caregivers and what is actually provided. Using an integrated knowledge translation approach, a stakeholder meeting was held among researchers, family caregivers, caregiver associations, clinicians, health care administrators, and policy makers. The objectives of the meeting were to review current research evidence and conduct multi-stakeholder dialogue on the potential gaps, facilitators, and barriers to the provision of caregiver supports. A two-day meeting was attended by 123 individuals. Three target populations of family caregivers were identified for discussion: caregivers of seniors with dementia, caregivers in end-of-life care, and caregivers of frail seniors with complex health needs. The results of this meeting can and are being used to inform the development of implementation research endeavours and policies targeted at providing evidence-informed caregiver supports.

  5. Could oxytocin administration during labor contribute to autism and related behavioral disorders?--A look at the literature. (United States)

    Wahl, Roy U Rojas


    This literature review summarizes recent potential evidence, most of which is at the molecular/mechanistic level, in support of Hollander's hypothesis that excess oxytocin (OT), possibly through OT administration at birth, could contribute to the development of autistic spectrum disorders and related syndromes by proposed down regulation of the OT receptor (OTR). In this review, recent molecular evidence for OTR internalization by excess OT is related to OT's reported effects on animal social behavior, favoring social bondage, notably in sheep, voles, rats and especially mice. Adding indications for OT's capability of crossing the maternal placenta and OT's possibility of crossing an underdeveloped or stressed infantile blood brain barrier at birth, a causal connection between OT excess and behavioral disorders such as autism can be supported from a molecular perspective. Possible strategies such as a thorough statistical analysis of numerous birth records as well as molecular studies such as radiotracing using labeled OT are proposed to test this hypothesis.

  18. Antecedents of Citizens' Satisfaction with Local Administration in Serbia

    Directory of Open Access Journals (Sweden)



    Full Text Available The role of local administration in recent decades has rapidly changed worldwide. Pressure for citizen-centrism coming from various interest groups has triggered the need to implement marketing and management concepts which characterize the business sector. Relatively few studies have focused on emerging trends of improvements in exceeding this bureaucratic paradigm in local administration. This study examines and explores citizens’ perception on determinants influencing their satisfaction with local administration services in Serbia. The study uses an exploratory approach. A questionnaire was distributed to 605 users of local administration services. Empirical evidence indicates that, from the citizens’ point of view, customer orientation, employees’ behavior and attitudes, as well as the process of service delivery impact the overall customer satisfaction with local administration. The study also discusses important implications on potential improvements of local administration.

  19. Recentralization of Kampala City Administration in Uganda

    Directory of Open Access Journals (Sweden)

    Nabukeera Madinah


    Full Text Available The government disseminated a new constitution in 1995 with the provision on decentralization of Article 176 2 (b that acted shortly before the rebirth of the local government act in 1997. Devolution as a form of decentralization transferred both political and administrative powers from the center to lower local councils specially to handle the responsibility of service delivery. Following the approval of the Kampala Capital City Authority (KCCA Act 2010, the city’s administration reverted to the central government. Detractors of decentralization allege that the conveyance in the policy and legislation for change of Kampala city administration was timely because decentralization failed to deliver desired services to residents. This article contends that recentralization of Kampala city administration was a necessary evil, it decreased the autonomy of sub-national governments in civil service administration, eroded accountability to the electorates, and transferred the allegiance of the accounting officer from local governments with and for which they work to the central government that designates and positions. To inflame accountability in local governments, the article champions for the reexamining of the KCCA Act 2010 to allow power sharing between the mayor and executive director to enhance bottom-up accountability, checks and balances, and for participation of central government in appointing of executive director to allow financial and security support. It additionally requests for a reconsideration of the 9th Parliament to lobby for the amendments owing to challenges in its implementation and impact on accountability.
