  1. Experimental interstellar organic chemistry - Preliminary findings (United States)

    Khare, B. N.; Sagan, C.


    Review of the results of some explicit experimental simulation of interstellar organic chemistry consisting in low-temperature high-vacuum UV irradiation of condensed simple gases known or suspected to be present in the interstellar medium. The results include the finding that acetonitrile may be present in the interstellar medium. The implication of this and other findings are discussed.

  2. Ecological investigations: vegetation studies, preliminary findings

    Energy Technology Data Exchange (ETDEWEB)

    Olgeirson, E.R.; Martin, R.B.


    The objective of the vegetation studies conducted on the research site is to produce a descriptive data base that can be applied to determinations of carrying capacity of the site and surrounding area. Additional information obtained about parameters that influence vegetation growth and maintenance of soil nutrients, and moisture and temperature regimes help define dynamic relationships that must be understood to effect successful revegetation and habitat rehabilitation. The descriptive vegetation baseline also provides a point of departure for design of future monitoring programs, and predictive models and strategies to be used in dealing with impact mitigation; in turn, monitoring programs and predictive modeling form the bases for making distinctions between natural trends and man-induced perturbations.

  3. Narcissism and consumer behaviour: a review and preliminary findings (United States)

    Cisek, Sylwia Z.; Sedikides, Constantine; Hart, Claire M.; Godwin, Hayward J.; Benson, Valerie; Liversedge, Simon P.


    We review the literature on the relation between narcissism and consumer behavior. Consumer behavior is sometimes guided by self-related motives (e.g., self-enhancement) rather than by rational economic considerations. Narcissism is a case in point. This personality trait reflects a self-centered, self-aggrandizing, dominant, and manipulative orientation. Narcissists are characterized by exhibitionism and vanity, and they see themselves as superior and entitled. To validate their grandiose self-image, narcissists purchase high-prestige products (i.e., luxurious, exclusive, flashy), show greater interest in the symbolic than utilitarian value of products, and distinguish themselves positively from others via their materialistic possessions. Our review lays the foundation for a novel methodological approach in which we explore how narcissism influences eye movement behavior during consumer decision-making. We conclude with a description of our experimental paradigm and report preliminary results. Our findings will provide insight into the mechanisms underlying narcissists’ conspicuous purchases. They will also likely have implications for theories of personality, consumer behavior, marketing, advertising, and visual cognition. PMID:24711797

  4. Preliminary findings of the LDEF Materials Special Investigation Group (United States)

    Stein, Bland A.; Pippin, H. Gary


    The retrieval of NASA's LDEF from low Earth orbit provided an opportunity for the study of long duration space environmental effects on materials. The five year, nine month flight of the LDEF greatly enhanced the potential value of most LDEF materials. NASA recognized this potential by forming the LDEF Space Environmental Effects on Materials Special Investigation Group (MSIG). Its goal is to explore the expanded materials analysis opportunities available in the LDEF structure and on experiment trays. The charter and scope of MSIG activities is presented, followed by an overview of the preliminary MSIG observations. These observations of low Earth orbit environmental effects on materials were made in-space during LDEF retrieval and during LDEF tray disintegration. Also presented are initial findings of lab analyses of LDEF materials. Included are effects of individual environmental parameters: atomic oxygen, ultraviolet radiation, meteoroid and debris impacts, thermal cycling, vacuum, and contamination, plus combined effects of these parameters. Materials considered include anodized aluminum, polymer matrix composites, polymer films, silvered Teflon thermal blankets, and a white thermal control paint.

  8. Attachment and Aggressive Manifestations in Younger Adulthood - "Preliminary Findings"

    Directory of Open Access Journals (Sweden)

    Tatiana Lorincová


    Full Text Available The main topic of the contribution was comparison between retrospective attachment (emocional warmth and rejection and aggressive manifestations (physical aggressivness, verbal aggressivness, anger and hostility among younger adulthood. Bowlby's theory of attachment was that once a core attachment style develops in an infant, it will influence and shape the nature of all intimate relations for the individual moving forward throughout the infant's life cycle. Authors Mikulincer and Shaver (2011 explain how these primary attachment experiences would affect future emotional, cognitive and behavioral processes. Secure adolescents, in comparison to insecure ones are perceived as being less aggressive. Research has pointed out that secure parental attachment promotes adaptive psychological functioning. The direct relationship between attachment security and aggressive/delinquent behaviour is in line with prior evidence that secure adolescents rate higher in terms of emotional and social adjustment, enjoy more positive relationships with their family and peers, and are less likely to engage in externalizing problems, such as antisocial and aggressive behaviours. On the other hand, insecure attachment is connected with aggressive and externalizing behaviour. Hypotheses were formulated on the base of theoretical background and our assumption was, that younger adults with emocional warmth attachment will have lower level of aggressive manifestations (physical aggression, verbal aggression, anger and hostility than younger adults with rejectional attachment. We used two standardized questionnaires for data collection, s.E.M.B.U. Questionnaire, which measured retrospective attachment (emocional warmth and rejection and Questionnaire of Aggressivness, which measured aggressive manifestations. We used statistical analysis and we found statistically significant differencies, which are preliminary findings from broader research, between emocional warmth

According to the FCTC Article 14 Guideline “Tobacco cessation medications should be made available to tobacco users wanting to quit and where possible be provided free or at an affordable cost”. Online survey was conducted among 9 countries (Armenia, Bangladesh, Brazil, India, Jordan, Nigeria, Spain, Turkey, Vietnam to determine availability, affordability, and prices of smoking cessation drugs in countries that are Global Bridges grantees and to make comparisons across them. Preliminary findings of the online survey will be summarized during the presentation.

  10. D-cycloserine and cocaine cue reactivity: preliminary findings. (United States)

    Price, Kimber L; McRae-Clark, Aimee L; Saladin, Michael E; Maria, Megan M Moran-Santa; DeSantis, Stacia M; Back, Sudie E; Brady, Kathleen T


    D-cycloserine (DCS), a partial glutamate N-methyl-D-aspartic acid (NMDA) receptor agonist, enhances extinction of conditioned fear responding in rodents and facilitates exposure-based learning in humans with anxiety disorders. This preliminary study investigates DCS pretreatment on response to cocaine cues in cocaine-dependent subjects. Ten cocaine-dependent subjects were randomly assigned to receive either 50 mg DCS or matching placebo two hours before each of two 1-hour cocaine cue exposure sessions one day apart. HR and craving ratings were obtained before and during cue exposure sessions. There was a trend towards increased craving to cocaine cues in cocaine-dependent individuals after administration of DCS. The administration of DCS prior to cue exposure sessions may facilitate response activation. While facilitation of extinction-based learning by DCS may have therapeutic potential for cocaine dependence, this drug may exhibit a different profile in cocaine-dependent individuals as compared to those with anxiety disorders.

  12. Comparing shame in clinical and nonclinical populations: Preliminary findings. (United States)

    Dyer, Kevin F W; Dorahy, Martin J; Corry, Mary; Black, Rebecca; Matheson, Laura; Coles, Holly; Curran, David; Seager, Lenaire; Middleton, Warwick


    To conduct a preliminary study comparing different trauma and clinical populations on types of shame coping style and levels of state shame and guilt. A mixed independent groups/correlational design was employed. Participants were recruited by convenience sampling of 3 clinical populations-complex trauma (n = 65), dissociative identity disorder (DID; n = 20), and general mental health (n = 41)-and a control group of healthy volunteers (n = 125). All participants were given (a) the Compass of Shame Scale, which measures the four common shame coping behaviors/styles of "withdrawal," "attack self," "attack other," and "avoidance," and (b) the State Shame and Guilt Scale, which assesses state shame, guilt, and pride. The DID group exhibited significantly higher levels of "attack self," "withdrawal," and "avoidance" relative to the other groups. The complex trauma and general mental health groups did not differ on any shame variable. All three clinical groups had significantly greater levels of the "withdrawal" coping style and significantly impaired shame/guilt/pride relative to the healthy volunteers. "Attack self" emerged as a significant predictor of increased state shame in the complex trauma, general mental health, and healthy volunteer groups, whereas "withdrawal" was the sole predictor of state shame in the DID group. DID emerged as having a different profile of shame processes compared to the other clinical groups, whereas the complex trauma and general mental health groups had comparable shame levels and variable relationships. These differential profiles of shame coping and state shame are discussed with reference to assessment and treatment. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  14. Metaphors of Entrepreneurship among Polish Students: Preliminary Research Findings

    Directory of Open Access Journals (Sweden)

    Michał Chmielecki


    Full Text Available Objective: In Poland entrepreneurship is often viewed as an extremely risky process and entrepreneurs are often portrayed in a negative light. The research goals  of our exploratory study is to identify  the entreprenurship metaphors among Polish management students.   Research Design & Methods: Authors decided to run both qualitative and quantitative research.  In the first part we addressed 124 management students on three levels BA, MA and MBA.  The respondents were asked to give their metaphorical expressions on paper. The next step was to prepare a questionnaire based on 7 point Likert scale. This questionnaire was run among  BA management student group composed of 82 students Findings: Our results suggest that there are several major entrepreneurial narratives evident among all three groups including creativity and innovation, competition, war, journey, risk, adventure and exploitation.  Implications & Recommendations: The empirical findings serve as a starting point for further in-depth research in this area. It is recommended that in order to gain a complete picture of the issues underlying the results, both qualitative and quantitative research on a bigger sample should be undertaken. Contribution & Value Added: The originality of this work lies in studying some aspects of entrepreneurship metaphors among non-entrepreneurs in Poland.  With regards to the research limitation, it must be highlighted that it was a pilot study and the results cannot be generalized.

    Ozuna, A G Cino; Rowland, R R R; Nietfeld, J C; Kerrigan, M A; Dekkers, J C M; Wyatt, C R


    Weaned pigs from a line bred for increased feed efficiency were enrolled in a study of the role of host genes in the response to infection with Porcine Reproductive and Respiratory Syndrome Virus (PRRSV). Four of the pigs were euthanatized early in the study due to weight loss with illness and poor body condition; 2 pigs before PRRSV infection and the other 2 pigs approximately 2 weeks after virus inoculation. The 2 inoculated pigs failed to produce PRRSV-specific antibodies. Gross findings included pneumonia, absence of a detectable thymus, and small secondary lymphoid tissues. Histologically, lymph nodes, spleen, tonsils, and Peyer's patches were sparsely cellular with decreased to absent T and B lymphocytes.

  16. Preliminary findings from the Oranga Niho dental student outplacement project. (United States)

    Anderson, V R; Rapana, S T; Broughton, J R; Seymour, G J; Rich, A M


    To examine stakeholder perspectives of the Bachelor of Dental Surgery 2012-2013 clinical outplacement programme with Māori Oral Health Providers (MOHPs) and inform the programme's ongoing development. A mixed methods kaupapa Māori action research project. Six North Island MOHPs and the University of Otago Faculty of Dentistry. Online questionnaires were used to conduct a pre- and post-outplacement survey of dental students and a twice-yearly survey of all MOHP-based clinical supervisors. Paper questionnaires were used to survey adult clients and caregivers of child clients that the students treated. Data were analysed descriptively and thematically. 68 (61%) of the 112 eligible students completed the pre- and post-outplacement questionnaires; 31 clinical supervisor questionnaire responses were received representing all six MOHPs; and 426 client and 130 caregiver questionnaire responses were received from five MOHPs. 79% of students felt well prepared for outplacement and 75% indicated that they would consider working for a MOHP in future. Of the clinical supervisors, 93% indicated that the students were adequately prepared for outplacement, and 68%, that they would recommend one or more students for employment. However, 58% associated the outplacements with decreased productivity. More than 97% of adult clients and caregivers of child clients were pleased with the care that the students provided. Recommendations for strengthening the outplacement programme included: increasing communication between the Faculty, MOHPs and students; addressing the financial cost of the programme to the MOHPs; and providing more support for clinical supervisors.

  17. Quality Cost in the Construction Industry ' Preliminary Findings in Malaysia

    Directory of Open Access Journals (Sweden)

    Mukhtar Che Ali


    Full Text Available One of the key areas being emphasis in ISO 9001 Quality Management System (QMS is performance measurement towards continual improvement. Among the primary measuring tools is quality cost approach. Quality cost has been well practice in manufacturing sector but slowly gain its importance in construction industry. In fact Project Management Body of Knowledge (PMBOK has reckoned quality cost as one of the tool and technique in few of its management processes. In view of such circumstances that has prompted an effort to undertake a study to ascertain the level of knowledge and practice on quality cost in Malaysian construction landscape. The targeted group of respondents was the personnel in the project management team. Capitalizing Construction Industry Development Board (CIDB National Electronic Tendering Initiatives (NETI road shows which were held in year 2007 throughout the country, the author was able to garner 263 respondents representing the project management team. Subsequently the data gathered from the completed forms were analyzed using Statistical Package for Social Science (SPSS software. General findings indicated that the level of knowledge and practice on quality cost among the project management team were relatively low. One of the main contributing factors was poor knowledge in the area related to quality cost. Despite of such scenario most of the respondents showed their interest in acquiring knowledge in the field of quality cost. Hence quality cost approach is at the infancy stage in Malaysian construction industry.

  18. Allergies and Disease Severity in Childhood Narcolepsy: Preliminary Findings. (United States)

    Aydinoz, Secil; Huang, Yu-Shu; Gozal, David; Inocente, Clara O; Franco, Patricia; Kheirandish-Gozal, Leila


    Narcolepsy frequently begins in childhood, and is characterized by excessive daytime sleepiness, with the presence of cataplexy reflecting a more severe phenotype. Narcolepsy may result from genetic predisposition involving deregulation of immune pathways, particularly involving T helper 2 cells (Th2). Increased activation of Th2 cells is usually manifested as allergic conditions such as rhinitis, atopic dermatitis, and asthma. We hypothesized that the presence of allergic conditions indicative of increased Th2 balance may dampen the severity of the phenotype in children with narcolepsy. A retrospective chart review of childhood narcolepsy patients was conducted at three major pediatric sleep centers. Patients were divided into those with narcolepsy without cataplexy (NC-) and narcolepsy with cataplexy (NC+). Demographics, polysomnographic and multiple sleep latency test data, and extraction of information on the presence of allergic diseases such allergic rhinitis, atopic dermatitis, and asthma was performed. There were 468 children identified, with 193 children in NC- group and 275 patients in the NC+ group. Overall, NC+ children were significantly younger, had higher body mass index, and had shorter mean sleep latencies and increased sleep onset rapid eye movement events. The frequency of allergic conditions, particularly asthma and allergic rhinitis, was markedly lower in NC+ (58/275) compared to NC- patients (94/193; P narcolepsy. Current findings further suggest that an increased shift toward T helper 2 cells, as indicated by the presence of allergic conditions, may modulate the severity of the phenotype in childhood narcolepsy, and reduce the prevalence of cataplexy in these patients. © 2015 Associated Professional Sleep Societies, LLC.

    Scherder, Erik J A; Plooij, Bart; Achterberg, Wilco P; Pieper, Marjoleine; Wiegersma, Marije; Lobbezoo, Frank; Oosterman, Joukje M


    In a previous study, the levels of pain reported by patients with "possible" vascular dementia (VaD) were higher than those reported by older individuals without dementia. To examine experienced pain in patients with "probable" VaD, confirmed by brain imaging. Observational, cross sectional. Nursing home. The participants were 20 nursing home residents (14 females, 6 males) who met the NINDS-AIREN criteria for "probable" VaD and 22 nursing home residents with a normal mental status (18 females, 4 males). The patients were in a mild to moderate stage of dementia. All of the participants were suffering from arthritis/arthrosis or osteoporosis. Global cognitive functioning was measured by the Mini-Mental State Examination. Pain was assessed by the Coloured Analogue Scale (CAS: original and modified version) and the Faces Pain Scale. The Geriatric Depression Scale and the Symptom Checklist-90 were used to assess mood. The main finding was that, after controlling for mood, the pain levels indicated by patients with "probable" VaD (M = 102.32; standard deviation [SD] = 53.42) were significantly higher than those indicated by the control group (M = 59.17; SD = 38.75), only according to the CAS modified version (F[1,29]) = 5.62, P = 0.01, η2  = 0.16). As VaD patients may experience greater pain than controls, it is essential for prescribers to be aware of the presence of this neuropathology if these patients are to receive adequate treatment.

  4. A Clinician-Guided Nonsurgical Cosmetic Patient Information Module: Preliminary Findings. (United States)

    Warren, Hermine Jan


    In 2011, nearly 13 million nonsurgical cosmetic procedures were performed, representing a 6% increase from the previous year. Patients often present with unrealistic treatment expectations based on beauty industry standards and misinformation. In addition, because of the lack of competency standardization in this area, providers frequently deliver inconsistent educational information to their patients. The initial goal of the project was to evaluate the clinician-guided module, a 13-slide PowerPoint presentation that was disseminated to key stakeholders for preliminary review. A convenience sample of 10 women, aged 30-64 years, was recruited. Following exposure to the module, each participant was asked to fill out an evaluation composed of both closed- and open-ended responses, noting her experience with this type of educational tool. Quantitative data were analyzed using comparison of means, whereas qualitative data were examined for the emergence of themes. Initial findings suggested that patients and health care providers found the clinician-guided module informative and visually appealing and that they would recommend this module to peers and colleagues. Potential social change from this project may surface through increased patient knowledge and empowerment, awareness, safety, and satisfaction. The final project will compare the clinician-guided patient information module to standard patient information evaluating treatment expectations of dermal fillers. The ultimate impact of a clinician-guided information module may improve standardization in this arena and thus be of particular interest to members of the nonsurgical cosmetic community.

  6. Identifying benchmarks for discrepancy rates in preliminary interpretations provided by radiology trainees at an academic institution. (United States)

    Ruutiainen, Alexander T; Scanlon, Mary H; Itri, Jason N


    At many academic medical centers, radiology house staff provide preliminary interpretations for imaging studies after hours, the accuracy and timely availability of which are crucial to patient care. Nevertheless, these preliminary interpretations are sometimes discrepant with finalized attending reports. The rate of such discrepancies can provide valuable information for quality improvement. The aim of this study was to identify specific benchmarks for resident discrepancy rates by reviewing all 73,072 on-call reports generated at the authors' institution over 1 year. A custom-built interface called Orion was used to track all on-call reports generated in 2010. Reports graded as discrepant with major changes during attending review were automatically identified. The turnaround time (TAT) of all reports was measured. These data were used to identify specific benchmarks for resident performance on call. A total of 45,608 of 73,072 preliminary dictations (62%) were interpreted by residents; of these, 407 (0.89%) had major discrepancies. The major discrepancy rates varied among individual residents (0.2% to 1.8%), modalities, and level of resident training. On the basis of distributions, major discrepancy benchmarks were established for overall rate (1.7%) and for the modalities of conventional radiography (1.5%), CT (4.0%), and ultrasound (4.0%). The mean TAT was significantly shorter for the emergency department (46 minutes) than for inpatient services (144 minutes). A benchmark TAT of 1 hour has been adopted for all imaging studies performed through the emergency department. Identifying benchmarks for major discrepancy rates and TAT of preliminary interpretations by radiology trainees is a valuable first step for individual and departmental quality improvement.

  7. Volume of discrete brain structures in complex dissociative disorders: preliminary findings. (United States)

    Ehling, T; Nijenhuis, E R S; Krikke, A P


    Based on findings in traumatized animals and patients with posttraumatic stress disorder, and on traumatogenic models of complex dissociative disorders, it was hypothesized that (1) patients with complex dissociative disorders have smaller volumes of hippocampus, parahippocampal gyrus, and amygdala than normal controls, (2) these volumes are associated with severity of psychoform and somatoform dissociative symptoms, and (3) patients who recovered from dissociative identity disorder (DID) have more hippocampal volume that patients with florid DID. The preliminary findings of the study are supportive of these hypotheses. Psychotherapy for dissociative disorders may affect hippocampal volume, but longitudinal studies are required to document this potential causal relationship.

  8. Preliminary Findings from an Analysis of Building Energy Information System Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Granderson, Jessica; Piette, Mary Ann; Ghatikar, Girish; Price, Philip


    Energy information systems comprise software, data acquisition hardware, and communication systems that are intended to provide energy information to building energy and facilities managers, financial managers, and utilities. This technology has been commercially available for over a decade, however recent advances in Internet and other information technology, and analytical features have expanded the number of product options that are available. For example, features such as green house gas tracking, configurable energy analyses and enhanced interoperability are becoming increasingly common. Energy information systems are used in a variety of commercial buildings operations and environments, and can be characterized in a number of ways. Basic elements of these systems include web-based energy monitoring, web-based energy management linked to controls, demand response, and enterprise energy management applications. However the sheer number and variety of available systems complicate the selection of products to match the needs of a given user. In response, a framework was developed to define the capabilities of different types of energy information systems, and was applied to characterize approximately 30 technologies. Measurement is a critical component in managing energy consumption and energy information must be shared at all organizational levels to maintain persistent, efficient operations. Energy information systems are important to understand because they offer the analytical support to process measured data into information, and they provide the informational link between the primary actors who impact building energy efficiency - operators, facilities and energy managers, owners and corporate decision makers. In this paper, preliminary findings are presented, with a focus on overall trends and the general state of the technology. Key conclusions include the need to further pursue standardization and usability, x-y plotting as an under-supported feature, and

  9. Utilization of nondentist providers and attitudes toward new provider models: findings from the National Dental Practice-Based Research Network. (United States)

    Blue, Christine M; Funkhouser, D Ellen; Riggs, Sheila; Rindal, D Brad; Worley, Donald; Pihlstrom, Daniel J; Benjamin, Paul; Gilbert, Gregg H


    The purpose of this study was to quantify, within the National Dental Practice-Based Research Network, current utilization of dental hygienists and assistants with expanded functions and quantify network dentists' attitudes toward a new nondentist provider model - the dental therapist. National Dental Practice-Based Research Network practitioner-investigators participated in a single, cross-sectional administration of a questionnaire. Current nondentist providers are not being utilized by network practitioner-investigators to the fullest extent allowed by law. Minnesota practitioners, practitioners in large group practices, and those with prior experience with expanded-function nondentist providers delegate at a higher rate and had more-positive perceptions of the new dental therapist model. Expanding scopes of practice for dental hygienists and assistants has not translated to the maximal delegation allowed by law among network practices. This finding may provide insight into dentists' acceptance of newer nondentist provider models. © 2013 American Association of Public Health Dentistry.

  10. Growth and profitability in small privately held biotech firms: preliminary findings. (United States)

    Brännback, Malin; Carsrud, Alan; Renko, Maija; Ostermark, Ralf; Aaltonen, Jaana; Kiviluoto, Niklas


    This paper reports on preliminary findings on a study of the relationship of growth and profitability among small privately held Finnish Life Science firms. Previous research results concerning growth and profitability are mixed, ranging from strongly positive to a negative relationship. The conventional wisdom states that growth is a prerequisite for profitability. Our results suggest that the reverse is the case. A high profitability-low growth biotech firm is more probably to make the transition to high profitability-high growth than a firm that starts off with low profitability and high growth.

  11. Coordination in contractual relations: Some preliminary findings from the Malaysian housing industry

    Directory of Open Access Journals (Sweden)

    Suraya Ismail


    Full Text Available The traditional general procurement route found in many housing projects in Malaysia is conceptualized as a governance structure following the transaction cost economics (TCE approach. This approach has been used to examine governance structures in different economic sectors in several countries but evidence of its use in the context of developing countries is limited. This lack of evidence has prompted the authors to conduct a preliminary study to ascertain whether a TCE approach can explain construction governance structures in developing countries. This research does not discuss the trade-off that governs the choice of hybrids, market or hierarchies for organizing transactions. Rather, it takes advantage of existing research to substantiate the specific properties of hybrid organizations as governance structures. The main focus is coordination. Coordination is specified at two levels. At Level 1 is the coordination of specialization (i.e. the formation of the project team members and at Level 2 is the coordination mode of the contracting parties (client and contractor and the agents involved (the lead designer and project manage r. A case survey method was adopted. Preliminary findings seem to suggest that clients have used hierarchical themes in the contracts and high powered incentives to coordinate with in the contracting parties. The research findings suggest that all participants involved in the sample studied used governance structures symptomatic of a hybrid organization.

  12. Impacts from Deployment Barriers on the United States Wind Power Industry: Overview & Preliminary Findings (Presentation)

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, E.; Tegen, S.; Hand, M.; Heimiller, D.


    Regardless of cost and performance some wind projects are unable to proceed to commissioning as a result of deployment barriers. Principal deployment barriers in the industry today include: wildlife, public acceptance, access to transmission, and radar. To date, methods for understanding these non-technical barriers have failed to accurately characterize the costs imposed by deployment barriers and the degree of impact to the industry. Analytical challenges include limited data and modeling capabilities. Changes in policy and regulation, among other factors, also add complexity to analysis of impacts from deployment barriers. This presentation details preliminary results from new NREL analysis focused on quantifying the impact of deployment barriers on the wind resource of the United States, the installed cost of wind projects, and the total electric power system cost of a 20% wind energy future. In terms of impacts to wind project costs and developable land, preliminary findings suggest that deployment barriers are secondary to market drivers such as demand. Nevertheless, impacts to wind project costs are on the order of $100/kW and a substantial share of the potentially developable windy land in the United States is indeed affected by deployment barriers.

  13. Sexual Abuse against Children. Preliminary Findings of the Investigation Conducted in May 2008, by Gallup Institute

    Directory of Open Access Journals (Sweden)



    Full Text Available Sexual abuse against minors has become in the last decades an important social issue for specialists in several countries, including Romania. Although sexual victimization rates in various countries appear to have declined beginning with 1993,there is still a greater probability for children and teenagers to suffer from sexual aggression rather than adults. Despite the increased preoccupation with the issue of sexual abuse against children and the new knowledge acquired in this field, several aspects have been left unsolved, among which that of the accuracy of data collected and underrepresented statistics. This study is a preliminary analysis of the main findings of the investigation conducted in May 2008, by the Gallup Institute, at the request of the Institute of Sociology of the Romanian Academy and whose object was, among others, sexual abuse against children in Romania.

  14. Parents and Teachers‘ Voices of Quality Preschool: Preliminary findings from Indonesia

    Directory of Open Access Journals (Sweden)

    Edi Waluyo


    Full Text Available This paper describes preliminary findings of a study on Indonesian teachers and parents’ perspectives of quality preschool program. It departs in one hand from the context of the Indonesian government massive promotion of early childhood programs and on the other hand of the country top-down, government-dominated quality system. Moreover, it is contextualized within the growing body of literatures, which emphasizes the centrality of quality issues to early childhood service and the notion that quality is a complex, contextual, multifaceted construction and idea. This study found that even though parents and teachers’ constructions of quality share some commonalities with those of the government-constructed ones, they significantly differ. The government-constructed quality framework for example emphasizes on teacher formal qualification, but teachers and parents have moved beyond such formality and urged the importance of teacher personal character

  15. A phenomenographic investigation into Information Literacy in nursing practice - preliminary findings and methodological issues. (United States)

    Forster, Marc


    Information Literacy is essential to 'evidence-based practice'; without the ability to locate evidence, evidence-based practice is rendered extremely difficult if not impossible. There is currently little evidence to show how Information Literacy is experienced by nurses or what its parameters are within evidence-based practice and therefore whether Information Literacy educational interventions are actually promoting the correct knowledge and skills. Using phenomenographic interviews the author will attempt to discover how nurses experience Information Literacy. Insights from the findings will be used to map out its parameters and to put forward a theoretical model for a course or module to develop it effectively. This article presents preliminary findings, including 7 draft categories of description of how Information Literacy is experienced in nursing. This pilot study indicates that the complete findings may be of significant potential value in the promotion and development of Information Literacy education in nursing. It is argued that such insights into how nurses actually experience the phenomenon of Information Literacy can be used to develop potentially more effective, research-based, educational interventions.

  17. Keeping rail on track: preliminary findings on safety culture in Australian rail. (United States)

    Blewett, Verna; Rainbird, Sophia; Dorrian, Jill; Paterson, Jessica; Cattani, Marcus


    'Safety culture' is identified in the literature as a critical element of healthy and safe workplaces. How can rail organizations ensure that consistently effective work health and safety cultures are maintained across the diversity of their operations? This paper reports on research that is currently underway in the Australian rail industry aimed at producing a Model of Best Practice in Safety Culture for the industry. Located in rail organizations dedicated to the mining industry as well as urban rail and national freight operations, the research examines the constructs of organizational culture that impact on the development and maintenance of healthy and safe workplaces. The research uses a multi-method approach incorporating quantitative (survey) and qualitative (focus groups, interviews and document analysis) methods along with a participative process to identify interventions to improve the organization and develop plans for their implementation. The research uses as its analytical framework the 10 Platinum Rules, from the findings of earlier research in the New South Wales (Australia) mining industry, Digging Deeper. Data collection is underway at the time of writing and preliminary findings are presented at this stage. The research method may be adapted for use as a form of organizational review of safety and health in organizational culture.

    Reif, Carrie; Much, Kari


    The social networking use of university and college counseling center (UCCC) mental health providers has not been widely researched. Most of the 20 providers surveyed in this preliminary study reported engaging in social networking despite identifying pros and cons to its use. Participants' reported use of social media may indicate that social…

  19. The perspective of rural physicians providing abortion in Canada: qualitative findings of the BC Abortion Providers Survey (BCAPS). (United States)

    Dressler, Jennifer; Maughn, Nanamma; Soon, Judith A; Norman, Wendy V


    An increasing proportion of Canadian induced abortions are performed in large urban areas. For unknown reasons the number of rural abortion providers in Canadian provinces, such as British Columbia (BC), has declined substantially. This study explored the experiences of BC rural and urban physicians providing abortion services. The mixed methods BC Abortion Providers Survey employed self-administered questionnaires, distributed to all known current and some past BC abortion providers in 2011. The optional semi-structured interviews are the focus of this analysis. Interview questions probed the experiences, facilitators and challenges faced by abortion providers, and their future intentions. Interviews were transcribed and analyzed using cross-case and thematic analysis. Twenty interviews were completed and transcribed, representing 13/27 (48.1%) rural abortion providers, and 7/19 (36.8%) of urban providers in BC. Emerging themes differed between urban and rural providers. Most urban providers worked within clinics and reported a supportive environment. Rural physicians, all providing surgical abortions within hospitals, reported challenging barriers to provision including operating room scheduling, anesthetist and nursing logistical issues, high demand for services, professional isolation, and scarcity of replacement abortion providers. Many rural providers identified a need to "fly under the radar" in their small community. This first study of experiences among rural and urban abortion providers in Canada identifies addressable challenges faced by rural physicians. Rural providers expressed a need for increased support from hospital administration and policy. Further challenges identified include a desire for continuing professional education opportunities, and for available replacement providers.

  1. The Role of Distance Learning in Journalism: Preliminary Findings from Journalists’ Perspectives

    Directory of Open Access Journals (Sweden)

    Sofia Iordanidou


    Full Text Available This paper presents the preliminary findings of an ongoing research project focused on the importance of building learning tools and procedures that will help media professionals adjust to a constant changing environment. Adopting a mix of quantitative and qualitative methodology by conducting in depth interviews with journalists from Greece and Cyprus, and by running an online questionnaire, addressed to journalists as well as communication professionals, we try to define the role and the profile of the contemporary journalist, and how it has changed under the pressure and the potential, unleashed by new technologies and the global financial crisis. We study the development of lifelong learning programs, their impact and their results with an emphasis on distance learning. Through our research we conclude that there is a need to rethink journalism training and curricula by introducing new skills. In addition, lifelong learning in the form of distance learning seems to be a priority for most journalists in order to adjust to the current media landscape.

  2. Assessment of the contralesional corticospinal tract in early-onset pediatric hemiplegia: Preliminary findings. (United States)

    Hawe, Rachel L; Dewald, Jules P A


    While pediatric hemiplegia results from a unilateral lesion, the immature state of the brain at the time of injury increases the likelihood of observing changes in the non-lesioned hemisphere as well. The purpose of this preliminary study was to use diffusion tensor imaging to evaluate the contralesional corticospinal tracts in individuals with early-onset pediatric hemiplegia. Twelve individuals with pediatric hemiplegia and ten age-matched controls underwent diffusion tensor imaging (DTI). Corticospinal projections were reconstructed using probabilistic tractography for both the lesioned and contralesional side in pediatric hemiplegia as well as the dominant and non-dominant sides in control subjects. The contralesional tract was found to have decreased white matter integrity relative to control subjects. Compared to controls, the contralesional tract also showed increased tract volume. The increase in volume suggests the presence of ipsilateral corticospinal projections from the contralesional hemisphere that are maintained during development to control the paretic extremities. Decreases in integrity may be explained by diffuse damage or incomplete maturation. The findings of this study support the notion of bilateral motor involvement in pediatric hemiplegia, and the need to address bilateral neural changes as well as motor deficits in this population.

  3. Interhemispheric Functional Brain Connectivity in Neonates with Prenatal Alcohol Exposure: Preliminary Findings. (United States)

    Donald, Kirsten A; Ipser, Jonathan C; Howells, Fleur M; Roos, Annerine; Fouche, Jean-Paul; Riley, Edward P; Koen, Nastassja; Woods, Roger P; Biswal, Bharat; Zar, Heather J; Narr, Katherine L; Stein, Dan J


    Children exposed to alcohol in utero demonstrate reduced white matter microstructural integrity. While early evidence suggests altered functional brain connectivity in the lateralization of motor networks in school-age children with prenatal alcohol exposure (PAE), the specific effects of alcohol exposure on the establishment of intrinsic connectivity in early infancy have not been explored. Sixty subjects received functional imaging at 2 to 4 weeks of age for 6 to 8 minutes during quiet natural sleep. Thirteen alcohol-exposed (PAE) and 14 age-matched control (CTRL) participants with usable data were included in a multivariate model of connectivity between sensorimotor intrinsic functional connectivity networks. Seed-based analyses of group differences in interhemispheric connectivity of intrinsic motor networks were also conducted. The Dubowitz neurological assessment was performed at the imaging visit. Alcohol exposure was associated with significant increases in connectivity between somatosensory, motor networks, brainstem/thalamic, and striatal intrinsic networks. Reductions in interhemispheric connectivity of motor and somatosensory networks did not reach significance. Although results are preliminary, findings suggest PAE may disrupt the temporal coherence in blood oxygenation utilization in intrinsic networks underlying motor performance in newborn infants. Studies that employ longitudinal designs to investigate the effects of in utero alcohol exposure on the evolving resting-state networks will be key in establishing the distribution and timing of connectivity disturbances already described in older children.

  4. Technical and patient performance using a virtual reality-integrated telerehabilitation system: preliminary finding. (United States)

    Deutsch, Judith E; Lewis, Jeffrey A; Burdea, Grigore


    Telerehabilitation is the provision of rehabilitation services at a distance by a therapist at a remote location. Integration with virtual reality (VR) is a relatively new addition to this field. This paper describes the technical and patient performance of a telerehabilitation application the remote console (ReCon) that is integrated with a VR system. The VR system consists of the Rutgers Ankle prototype robot, a local PC which is connected with a remote PC connected over the Internet. Six individuals in the chronic phase poststroke participated in a four week training program. They used the robot to interact with two VR simulations, while the therapist was in the same room during the first three weeks or in another room during the fourth week. Technical and patient performance was assessed in the transition from the third to the fourth week of training. Technical performance of the system was assessed based on bandwidth and lag of message transmission, which were found to be suitable for clinic-to-clinic communication. Patient performance (in terms of accuracy of ankle movement, exercise duration and training efficiency, mechanical power of the ankle, and number of repetitions) did not decrease during telerehabilitation in the fourth week. These preliminary findings over a short telerehabilitation intervention support the feasibility of remote monitoring of VR-based telerehabilitation without adverse effects on patient performance.

  5. Assessing health-related resiliency in HIV+ Latin women: Preliminary psychometric findings.

    Directory of Open Access Journals (Sweden)

    Gladys J Jimenez-Torres

    Full Text Available HIV-associated vulnerabilities-especially those linked to psychological issues-and limited mental health-treatment resources have the potential to adversely affect the health statuses of individuals. The concept of resilience has been introduced in the literature to shift the emphasis from vulnerability to protective factors. Resilience, however, is an evolving construct and is measured in various ways, though rarely among underserved, minority populations. Herein, we present the preliminary psychometric properties of a sample of HIV-seropositive Puerto Rican women, measured using a newly developed health-related resilience scale.The Resilience Scales for Children and Adolescents, an instrument with solid test construction properties, acted as a model in the development (in both English and Spanish of the HRRS, providing the same dimensions and most of the same subscales. The present sample was nested within the Hispanic-Latino longitudinal cohort of women (HLLC, that is part of the NeuroAIDS Research Program at the University of Puerto Rico (UPR, Medical Sciences Campus (MSC. Forty-five consecutively recruited, HIV+ women from the HLLC completed a demographic survey, the HRRS, and the Beck Depression Inventory-I, Spanish version.The results demonstrate excellent overall internal consistency for the total HRRS score (α = 0.95. Each of the dimensional scores also evidenced acceptable internal consistency (α ≥ 0.88. All the dimensional and subscale content validity indices were above the 0.42 cut-off. Analysis revealed a significant negative correlation between the HRRS total score and BDI-I-S (r(45 = -0.453, p < 0.003.Albeit preliminary in nature, the present study provides support for the HRRS as a measure to assess resilience among individuals living with chronic medical conditions. Minority populations, especially non-English speaking ones, are understudied across the field of medicine, and when efforts are made to include these patient

  7. Farmers' Market Utilization among Supplemental Nutrition Assistance Program Recipients in New Orleans, Louisiana: Preliminary Findings. (United States)

    Nuss, Henry; Skizim, Meg; Afaneh, Hasheemah; Miele, Lucio; Sothern, Melinda


    Farmers' markets are increasingly being promoted as a means to provide fresh produce to poor and underserved communities. However, farmers' market (FM) use remains low among low-income patrons. The purpose of our study was to examine FM awareness and use, grocery shopping behaviors, and internet use among Supplemental Nutrition Assistance Program (SNAP) recipients. A descriptive analysis of preliminary data was performed to evaluate quantitative baseline data among SNAP recipients between June and August 2016 in New Orleans, Louisiana (N=51). Data were collected via a 42-item online survey that included demographics, internet use, FM awareness and use, health information seeking behaviors and fruit and vegetable purchasing behaviors. Less than half of the survey respondents (n=24) had ever been to a FM. Local grocery stores and Wal-Mart were most used for purchasing fruits and vegetables (88% and 84%, respectively). The most common sources of healthy eating information were Women, Infants and Children (WIC) and the internet, frequently accessed via smartphones. More than 80% of participants were not aware that local FMs accepted electronic benefit transfer payments as a form of payment. These results support the incorporation of promotional methodology that combines internet-based mobile technology and existing services (eg, WIC) as a viable strategy to improve farmers' market use among low-income populations. As most participants were not aware that participating FMs accept electronic benefit transfer payments, this fact should be emphasized in promotional material.

  8. Processing of different types of social threat in shyness: Preliminary findings of distinct functional neural connectivity. (United States)

    Tang, Alva; Beaton, Elliott A; Tatham, Erica; Schulkin, Jay; Hall, Geoffrey B; Schmidt, Louis A


    Current theory suggests that the processing of different types of threat is supported by distinct neural networks. Here we tested whether there are distinct neural correlates associated with different types of threat processing in shyness. Using fMRI and multivariate techniques, we compared neural responses and functional connectivity during the processing of imminent (i.e., congruent angry/angry face pairs) and ambiguous (i.e., incongruent angry/neutral face pairs) social threat in young adults selected for high and low shyness. To both types of threat processing, non-shy adults recruited a right medial prefrontal cortex (mPFC) network encompassing nodes of the default mode network involved in automatic emotion regulation, whereas shy adults recruited a right dorsal anterior cingulate cortex (dACC) network encompassing nodes of the frontoparietal network that instantiate active attentional and cognitive control. Furthermore, in shy adults, the mPFC interacted with the dACC network for ambiguous threat, but with a distinct network encompassing nodes of the salience network for imminent threat. These preliminary results expand our understanding of right mPFC function associated with temperamental shyness. They also provide initial evidence for differential neural networks associated with shy and non-shy profiles in the context of different types of social threat processing.

  9. Correlation of parenting style and pediatric behavior guidance strategies in the dental setting: preliminary findings. (United States)

    Aminabadi, Naser Asl; Farahani, Ramin Mostofi Zadeh


    The aim of this study was to investigate the influence of parenting style on the choice of proper behavior guidance strategies in pedodontics. Seventy-two children aged between 4 and 6 years (mean 5.12 years) with carious primary mandibular molars were selected. The Primary Caregivers' Practices Report (PCPR) was used to quantify authoritarian, permissive and authoritative aspects of the caregivers' parenting style. After inferior alveolar nerve block, carious lesions were removed and the teeth were restored using amalgam. The children's behavior during operation was assessed according to the sound, eye, and motor (SEM) scale. Communicative guidance, advance behavior guidance, parental separation, and deferred treatment were used for behavior management. The dominant authoritative score was observed in 50% of parents, permissive in 37.5%, and authoritarian in 12.5%. The mean SEM score in children belonging to authoritative parents was significantly lower than in children of permissive and of authoritarian parents (pparenting style. Advanced behavior guidance (protective stabilization) was applied in 16.7% of cases in the authoritative category and in 100% in the permissive and authoritarian categories. The use of restrictive devices (7.4%) and sedation (3.7%) was limited to the permissive category. Parental separation (40.7%) and deferred treatment (3.7%) were performed only in the permissive category. This study provides preliminary evidence that a child's reaction to restorative dental procedures is influenced by the nature of the caregiver's parenting style.

  10. Anatomy and histology as socially networked learning environments: some preliminary findings. (United States)

    Hafferty, Frederic W; Castellani, Brian; Hafferty, Philip K; Pawlina, Wojciech


    An exploratory study to better understand the "networked" life of the medical school as a learning environment. In a recent academic year, the authors gathered data during two six-week blocks of a sequential histology and anatomy course at a U.S. medical college. An eight-item questionnaire captured different dimensions of student interactions. The student cohort/network was 48 first-year medical students. Using social network analysis (SNA), the authors focused on (1) the initial structure and the evolution of informal class networks over time, (2) how informal class networks compare to formal in-class small-group assignments in influencing student information gathering, and (3) how peer assignment of professionalism role model status is shaped more by informal than formal ties. In examining these latter two issues, the authors explored not only how formal group assignment persisted over time but also how it functioned to prevent the tendency for groupings based on gender or ethnicity. The study revealed an evolving dynamic between the formal small-group learning structure of the course blocks and the emergence of informal student networks. For example, whereas formal group membership did influence in-class questions and did prevent formation of groups of like gender and ethnicity, outside-class questions and professionalism were influenced more by informal group ties where gender and, to a much lesser extent, ethnicity influence student information gathering. The richness of these preliminary findings suggests that SNA may be a useful tool in examining an array of medical student learning encounters.

  11. Effects of climate change on Pacific Northwest water-related resources: Summary of preliminary findings

    Energy Technology Data Exchange (ETDEWEB)

    Scott, M.J.; Sands, R.D.; Vail, L.W.; Chatters, J.C.; Neitzel, D.A.; Shankle, S.A.


    The Pacific Northwest Case Study is a multi-agency analysis of atmospheric/climatic change impacts on the Pacific Northwest (which includes Washington, Oregon, Idaho, and portions of the Columbia River Basin in Western Montana). The purpose of the case study, which began in fiscal year 1991, was to develop and test analytical tools, as well as to develop an assessment of the effects of climate change on climate-sensitive natural resources of the Pacific Northwest and economic sectors dependent on them. The overall study, jointly funded by the US Department of Energy (DOE) and the US Environmental Protection Agency, was a broad-based, reconnaissance-level study to identify potential climate impacts on agriculture, coastal resources, forest resources, and irrigation in the Pacific Northwest. DOE participated in the reconnaissance study, with responsibility for hydroelectric and water supply issues. While this report briefly discusses a broader array of water issues, attention is mainly focused on three aspects of the water study: (1) the effects of the region`s higher temperatures on the demand for electric power (which in turn puts additional demand on hydroelectric resources of the region); (2) the effects of higher temperatures and changes, both in precipitation amounts and seasonality, on river flows and hydroelectric supply; and (3) the effect of higher temperatures and changed precipitation amounts and seasonality on salmonid resources -- particularly the rearing conditions in tributaries of the Columbia River Basin. Because the meaning of regional climate forecasts is still quite uncertain, most of the preliminary findings are based on sensitivity analyses and historical analog climate scenarios.

  12. Preliminary fMRI findings in experimentally sleep-restricted adolescents engaged in a working memory task

    Directory of Open Access Journals (Sweden)

    Tlustos Sarah J


    Full Text Available Abstract Here we report preliminary findings from a small-sample functional magnetic resonance imaging (fMRI study of healthy adolescents who completed a working memory task in the context of a chronic sleep restriction experiment. Findings were consistent with those previously obtained on acutely sleep-deprived adults. Our data suggest that, when asked to maintain attention and burdened by chronic sleep restriction, the adolescent brain responds via compensatory mechanisms that accentuate the typical activation patterns of attention-relevant brain regions. Specifically, it appeared that regions that are normally active during an attention-demanding working memory task in the well-rested brain became even more active to maintain performance after chronic sleep restriction. In contrast, regions in which activity is normally suppressed during such a task in the well-rested brain showed even greater suppression to maintain performance after chronic sleep restriction. Although limited by the small sample, study results provide important evidence of feasibility, as well as guidance for future research into the functional neurological effects of chronic sleep restriction in general, the effects of sleep restriction in children and adolescents, and the neuroscience of attention and its disorders in children.

  13. Technology for dementia: attitudes and practices of occupational therapists in providing assistive technology for way finding. (United States)

    Jarvis, Fiona; Clemson, Lindy Maxted; Mackenzie, Lynette


    One of the many difficulties a person with dementia can experience is difficulty with way finding and subsequently getting lost in the community. Prescriptions of assistive technology are a key role for occupational therapists. This study aimed to describe the attitudes and practices of occupational therapists in recommending and using assistive technology for persons with dementia who have difficulties with way finding in the community. An online survey was distributed to members of Occupational Therapy Australia NSW and included 25 items on demographics, frequency of use of assistive technology and assessment. A total of 85 occupational therapists responded to the survey. Significant differences were identified in the approaches used, the types of assistive technology used and the evaluation of outcomes, between community-based and hospital-based occupational therapists. Over half of the participants had never prescribed any of the assistive devices listed in the survey for people with dementia. The most frequently prescribed assistive devices were low-tech items that were already freely available to carers and other professions. Therapists used a conservative approach to problem solving with their clients with dementia. There is a limited understanding from occupational therapists about available interventions for people with dementia. Implications for Rehabilitation There is limited awareness on how assistive technology might be used to support occupational performance for persons with dementia. This survey suggests that occupational therapists experience barriers in identifying and providing appropriate assistive technology for this group. Access to targeted education and online resources for occupational therapists is recommended to provide better awareness of the types of assistive technology available to assist persons with dementia and their caregivers.

    To determine the association between the self-report of pain and disability and findings on lumbar MR images, and to compare two different health care providers in Spanish patients with low back pain (LBP). Cross-sectional A total of 278 patients, 137 men and 141 women aged 44{+-}14 years submitted with low back pain (LBP) were studied. One hundred and nine patients were from the National Health System (NHS) and 169 from private practice. Patients with previous discitis, surgery, neoplasm or traumatic episodes were excluded. Every patient completed a disability questionnaire with six core items, providing a score of disability from 2 to 28. All patients had sagittal spin-echo T1 and turbo spin-echo T2, axial proton-density and MR myelography weighted images. MR images of the two most affected disc levels were read, offering an MR imaging score from 0 to 30. Patients with a combination of LBP and sciatica showed the highest levels of disability (p=0.002). MR imaging scores only correlated with pain interference with normal work (p=0.04), but not with other disability questions. Patients from the NHS showed greater disability scores than private ones (p=0.001) and higher MR imaging scores (p=0.01). In patients with LBP, MR imaging only correlates with pain interference with work but not with other disability questions. Differences are found between private and NHS patients, the latter being more physically affected. (orig.)

  17. Functional magnetic resonance imaging (fMRI of attention processes in presumed obligate carriers of schizophrenia: preliminary findings

    Directory of Open Access Journals (Sweden)

    Morris Robin G


    Full Text Available Abstract Background Presumed obligate carriers (POCs are the first-degree relatives of people with schizophrenia who, although do not exhibit the disorder, are in direct lineage of it. Thus, this subpopulation of first-degree relatives could provide very important information with regard to the investigation of endophenotypes for schizophrenia that could clarify the often contradictory findings in schizophrenia high-risk populations. To date, despite the extant literature on schizophrenia endophenotypes, we are only aware of one other study that examined the neural mechanisms that underlie cognitive abnormalities in this group. The aim of this study was to investigate whether a more homogeneous group of relatives, such as POCs, have neural abnormalities that may be related to schizophrenia. Methods We used functional magnetic resonance imaging (fMRI to collect blood oxygenated level dependent (BOLD response data in six POCs and eight unrelated healthy controls while performing under conditions of sustained, selective and divided attention. Results The POCs indicated alterations in a widely distributed network of regions involved in attention processes, such as the prefrontal and temporal (including the parahippocampal gyrus cortices, in addition to the anterior cingulate gyrus. More specifically, a general reduction in BOLD response was found in these areas compared to the healthy participants during attention processes. Conclusion These preliminary findings of decreased activity in POCs indicate that this more homogeneous population of unaffected relatives share similar neural abnormalities with people with schizophrenia, suggesting that reduced BOLD activity in the attention network may be an intermediate marker for schizophrenia.

  18. Student Evaluation of Teaching (SET in Web-based Classes: Preliminary Findings and a Call for Further Research

    Directory of Open Access Journals (Sweden)

    Karen A. Loveland, Ph.D.


    Full Text Available Student evaluation of teaching (SET is important to faculty because SET ratings help faculty improve performance and are often used as the basis for evaluations of teaching effectiveness in administrative decisions (e.g., tenure. Researchers have conducted over 2,000 studies on SET during the past 70 years. However, despite the explosive growth in online education during the past decade, researchers have largely neglected the use of SET to evaluate teaching effectiveness in online courses. This exploratory study analyzed the actual SET data collected during a single semester at a large mid-western college that offers over 250 online/Web-based classes. The data included five dependent and eighteen independent measures of teaching effectiveness. The results indicate that average SET ratings in online classes are significantly lower than the average ratings in on-campus classes across all five dependent measures. This finding offers preliminary empirical support for anecdotal evidence cited by earlier authors in this field. Furthermore, regression analysis of the full model for each dependent variable indicated that the independent variables explained a significant portion of the variance in SET ratings. Examination of the standardized beta coefficients revealed that the strength and significance of the independent variables varied across the five dependent measures. Findings also indicate that organization of the course materials had a strong impact on all five measures of overall teaching effectiveness. Other variables including clarity of the instructor’s writing, timeliness in providing feedback, and interest in whether students learned were also significant factors in models that measured instructor effectiveness (as opposed to models that measured quality of course content. The paper concludes with a discussion of the implications of this study for administrators, faculty, and researchers.

Approximately 250 pairs of (contaminated and uncontaminated) soil samples were obtained from nine different sub-catchments located in four different European countries; namely, France, Germany, Switzerland and the UK. Sample pairs were sub-divided into contaminated & uncontaminated soils and each variable was subjected to a pair-wise statistical test; firstly for all catchments combined, and then on a catchment-by-catchment basis, to determine whether differences were significant. In addition to the above analyses, further evidence of spatial and topographic colonisation tendencies was sought from digital imagery captured using a remotely-controlled drone (quadcopter) flown along a ca. 1.0 km section of contaminated river corridor. Images were georeferenced, displayed together in a Geographic Information System (GIS) and used to construct a 3-dimensional digital elevation model (DEM). The DEM was interrogated to determine the presence / absence of colonisation trends (i.e. a tendency to colonise low-lying areas). This communication reports preliminary findings from this ongoing work and discusses key implications and possible future directions.

  20. Treatment of word-finding deficits in fluent aphasia through the manipulation of spatial attention: Preliminary findings. (United States)

    Dotson, Vonetta M; Singletary, Floris; Fuller, Renee; Koehler, Shirley; Moore, Anna Bacon; Gonzalez Rothi, Leslie J; Crosson, Bruce


    BACKGROUND: Attention, the processing of one source of information to the exclusion of others, is important for most cognitive processes, including language. Evidence suggests not only that dysfunctional attention mechanisms contribute to language deficits after stroke, but also that orienting attention to a patient's ipsilesional hemispace recruits attention mechanisms in the intact hemisphere and improves language functions in some persons with aphasia. AIMS: The aim of the current research was to offer proof of concept for the strategy of improving picture-naming performance in fluent aphasia by moving stimuli into the left hemispace. It was hypothesised that repeated orientation of attention to the ipsilesional hemispace during picture naming would lead to improved naming accuracy for participants with fluent aphasia. METHODS #ENTITYSTARTX00026; PROCEDURES: Three participants with stable fluent aphasia received daily treatment sessions that consisted of naming simple line drawings presented 45 degrees to the left of body midline on a computer monitor. Naming probes were administered before initiation of the treatment protocol to establish a baseline, and before each treatment session to measure change during treatment. The C statistic was used to establish the stability of baseline performance and to determine whether the slope of the treatment phases differed significantly from the slope of the baseline. OUTCOMES #ENTITYSTARTX00026; RESULTS: Two of the three participants showed significant improvement over baseline performance in the percent correct of naming probes. One participant showed no improvement over baseline accuracy. CONCLUSIONS: Results suggest that engaging right-hemisphere attention mechanisms may improve naming accuracy in some people with fluent aphasia. Findings justify further investigation of this treatment in a larger controlled study.

    DEFF Research Database (Denmark)

    Jain, Veena; Mathur, Vijay Prakash; Pillai, Rajath


    PURPOSE: This preliminary hospital based study was designed to measure the mean maximum bite force (MMBF) in healthy Indian individuals. An attempt was made to correlate MMBF with body mass index (BMI) and some of the anthropometric features. METHODOLOGY: A total of 358 healthy subjects in the age...... bite force was recorded on both (right and left) sides using a specially designed piezoelectric transducer based device. RESULTS: The MMBF in Indian individuals was found to be 372.39 ± 175.93 Newton (N). Males had significantly higher (P = 0.000) MMBF (448.47 ± 191.82 N) as compared to females (296...

  3. Relationship Dissolution and Psychologically Aggressive Dating Relationships: Preliminary Findings From a College-Based Relationship Education Course. (United States)

    Negash, Sesen; Cravens, Jaclyn D; Brown, Preston C; Fincham, Frank D

    This study evaluated the impact of a relationship education program, delivered as part of a college course, among students (N = 152) who reported experiencing psychological aggression in their exclusive dating relationship. Preliminary results showed that compared to those in the control group, participants receiving relationship education were significantly more likely to end their romantic relationship, even after controlling for relationship satisfaction. Furthermore, when relationship termination occurred, those in the intervention group were significantly more likely to attribute the breakup to their participation in the class as compared to those in the control group. The tentative findings are an important preliminary step in assessing the benefits of relationship education in reducing the risk of psychological aggression among college students.

  4. Older adult stroke survivors discussing poststroke depressive symptoms with a healthcare provider: a preliminary analysis. (United States)

    Klinedinst, N Jennifer; Clark, Patricia C; Dunbar, Sandra B


    The purposes of this study were to examine the relationship between the poststroke depressive symptoms, older adult stroke survivors' perceptions of the depressive symptoms, and the congruence with an informal caregiver about the presence of depressive symptoms, and comfort talking to the health care provider with whether or not older stroke survivors discussed their depressive symptoms with a health care provider. A cross-sectional study where 44 caregiver/older adult stroke survivor dyads completed questionnaires including the Center for Epidemiologic Studies Depression Scale, Symptom Perception Questionnaire, and reporting of depressive symptoms to the health care provider via one time interview. Thirty-seven percent (n = 16) of all older stroke survivors reported depressive symptoms to their health care provider. Of the stroke survivors who had high levels of depressive symptoms (CESD ≥ 16; n = 11), seven reported the depressive symptoms to their health care provider. Identifying the symptoms as possible depression and attributing the cause of the depressive symptoms to the stroke were related to stroke survivors reporting the depressive symptoms to a health care provider. High functioning, older stroke survivors may benefit from strategies to help them identify when they experience depressive symptoms, in order to be able to play an active role in their recovery by appropriately discussing their symptoms with a health care provider.

  7. Using telepsychology to provide a group parenting program: A preliminary evaluation of effectiveness. (United States)

    Reese, Robert J; Slone, Norah C; Soares, Neelkamal; Sprang, Rob


    Telepsychology offers the potential to reach rural and underserved children and families with mental health concerns. The current study evaluated the effects of using videoconferencing technology to deliver an evidence-based parenting program, the Group Triple P Positive Parenting Program (Group Triple P; Turner, Markie-Dadds, & Sanders, 2002), with families who had a child experiencing behavioral problems. Using a pre/post design, families (N = 13) from low socioeconomic backgrounds in Kentucky completed the Group Triple P via a videoconferencing delivery format. A benchmarking strategy (Weersing & Hamilton, 2005) indicated that treatment effect sizes for the videoconferencing format were generally comparable to treatment effect sizes for Group Triple P studies conducted in-person. Specifically, child behavior and parenting outcomes were similar across delivery formats. Implications of the study's findings and future directions for telepsychology research and practice with underserved families and children are discussed. (c) 2015 APA, all rights reserved).

    Chung, Yoon Ho; Lee, Young Seok; Kim, Ji Hye; Han, Heon; Chung, Hyo Sun; Cha, Yoo Mi; Kim, Young Chae; Kim, Sang Hee [Chungang Gil Hospital, Inchon (Korea, Republic of)


    To evaluate high resolution CT(HRCT) findings in infants with bronchopulmonary dysplasia(BPD). In 13 infants(age range, 1-12 months;11 premature babies, two full-term babies; birth weight, 0.97-3.88kg;mean 2,03kg) with clinico-radiologically suggested BPD, HRCT findings of the lung were reviewed retrospectively. Spiral CT using ultra high bone algorithm, 1mm collimation with 5-8mm interval, and 0.7sec scan time was performed without regard to breathing-control of infants. Three radiologists each analysed the HRCT findings twice. HRCT findings of BPD were as follows:parenchymal bands(n=13), interlobular septal thickenings (n=12), multifocal hyperaeration involving lobar or segmental distribution(n=7), and involving lobular distribution or small cyst-like lesion(n=4), centrilobular nodules(n=7), consolidation and/or atelectasis(n=7), and bronchovascular bundle thickening(n=6). Parenchymal bands, interlobular septal thickenings, and multifocal hyperaerations were the major findings in cases of bronchopulmonary dysplasia whereas, centrilobular nodules, consolidation and/or atelectasis, and bronchovascular bundle thickenings were the minor findings. These findings may be used as basic data in the evaluation of BPD in future studies.

  9. Gratitude, abstinence, and alcohol use disorders: Report of a preliminary finding. (United States)

    Krentzman, Amy R


    Gratitude is a central component of addiction recovery for many, yet it has received scant attention in addiction research. In a sample of 67 individuals entering abstinence-based alcohol-use-disorder treatment, this study employed gratitude and abstinence variables from sequential assessments (baseline, 6months, 12months) to model theorized causal relationships: gratitude would increase pre-post treatment and gratitude after treatment would predict greater percent days abstinent 6months later. Neither hypothesis was supported. This unexpected result led to the theory that gratitude for sobriety was the construct of interest; therefore, the association between gratitude and future abstinence would be positive among those already abstinent. Thus, post-treatment abstinence was tested as a moderator of the effect of gratitude on future abstinence: this effect was statistically significant. For those who were abstinent after treatment, the relationship between gratitude and future abstinence was positive; for those drinking most frequently after treatment, the relationship between gratitude and future abstinence was negative. In this preliminary study, dispositional tendency to affirm that there is much to be thankful for appeared to perpetuate the status quo-frequent drinkers with high gratitude were drinking frequently 6months later; abstinent individuals with high gratitude were abstinent 6months later. Gratitude exercises might be contraindicated for clients who are drinking frequently and have abstinence as their treatment goal. Copyright © 2017 Elsevier Inc. All rights reserved.

  10. Rape-related cognitive distortions: Preliminary findings on the role of early maladaptive schemas. (United States)

    Sigre-Leirós, Vera; Carvalho, Joana; Nobre, Pedro J


    Despite the important focus on the notion of cognitive distortions in the sexual offending area, the relevance of underlying cognitive schemas in sexual offenders has also been suggested. The aim of the present study was to investigate a potential relationship between Early Maladaptive Schemas (EMSs) and cognitive distortions in rapists. A total of 33 men convicted for rape completed the Bumby Rape Scale (BRS), the Young Schema Questionnaire - Short form-3 (YSQ-S3), the Brief Symptom Inventory (BSI), and the Socially Desirable Response Set Measure (SDRS-5). Results showed a significant relationship between the impaired limits schematic domain and the Justifying Rape dimension of the BRS. Specifically, after controlling for psychological distress levels and social desirability tendency, the entitlement/grandiosity schema from the impaired limits domain was a significant predictor of cognitive distortions related to Justifying Rape themes. Overall, despite preliminary, there is some evidence that the Young's Schema-Focused model namely the impaired limits dimension may contribute for the conceptualization of cognitive distortions in rapists and further investigation is recommended.

  11. Informationist programme in support of biomedical research: a programme description and preliminary findings of an evaluation. (United States)

    Whitmore, Susan C; Grefsheim, Suzanne F; Rankin, Jocelyn A


    The informationist programme at the Library of the National Institutes of Health (NIH) in Bethesda, MD, USA has grown to 14 informationists working with 40 clinical and basic science research teams. This case report, intended to contribute to the literature on informationist programmes, describes the NIH informationist programme, including implementation experiences, the informationists' training programme, their job responsibilities and programme outcomes. The NIH informationist programme was designed to enhance the library's service capacity. Over time, the steps for introducing the service to new groups were formalized to ensure support by leadership, the team being served and the library. Job responsibilities also evolved from traditional library roles to a wide range of knowledge management activities. The commitment by the informationist, the team and the library to continuous learning is critical to the programme's success. RESULTS / OUTCOMES: NIH scientists reported that informationists saved them time and contributed to teamwork with expert searching and point-of-need instruction. Process evaluation helped refine the programme. High-level, preliminary outcomes were identified from a survey of scientists receiving informationist services, along with key informant interviews. Process evaluation examined service implementation, informationists' training and service components. Anecdotal evidence has also indicated a favourable response to the programme.

  12. Preliminary Findings in the Development of a Theoretical Framework for Investigating ICT Integration in Teacher Education

    Directory of Open Access Journals (Sweden)

    Suthagar Narasuman


    Full Text Available The following report is the result of a preliminary investigation in the development of a theoretical framework for investigating ICT integration, particularly in TESL (Teaching of English as a Second Language teacher training. The study is primarily an empirical effort to develop a theoretical framework for investigating ICT integration in TESL teacher training. In identifying the predictive variables for the framework, the researchers conducted an intensive review of the literature which included a review of various models used in studies on ICT integration. The contributing variables identified in the present study were age, gender, experience, ICT proficiency, attitude, access to ICT infrastructure, support services, and exposure to ICT professional development programmes. In developing the framework, the study sought to determine the extent to which the observed variability in ICT integration could be predicted by these factors. The sample comprised 266 respondents working at the faculty or English Language Unit in various teacher training institutions across the country. The study predominantly employed quantitative methods of data collection. Interview data was used to corroborate information derived from the survey data.

  13. Lingual-Alveolar Contact Pressure During Speech in Amyotrophic Lateral Sclerosis: Preliminary Findings. (United States)

    Searl, Jeff; Knollhoff, Stephanie; Barohn, Richard J


    This preliminary study on lingual-alveolar contact pressures (LACP) in people with amyotrophic lateral sclerosis (ALS) had several aims: (a) to evaluate whether the protocol induced fatigue, (b) to compare LACP during speech (LACP-Sp) and during maximum isometric pressing (LACP-Max) in people with ALS (PALS) versus healthy controls, (c) to compare the percentage of LACP-Max utilized during speech (%Max) for PALS versus controls, and (d) to evaluate relationships between LACP-Sp and LACP-Max with word intelligibility. Thirteen PALS and 12 healthy volunteers produced /t, d, s, z, l, n/ sounds while LACP-Sp was recorded. LACP-Max was obtained before and after the speech protocol. Word intelligibility was obtained from auditory-perceptual judgments. LACP-Max values measured before and after completion of the speech protocol did not differ. LACP-Sp and LACP-Max were statistically lower in the ALS bulbar group compared with controls and PALS with only spinal symptoms. There was no statistical difference between groups for %Max. LACP-Sp and LACP-Max were correlated with word intelligibility. It was feasible to obtain LACP-Sp measures without inducing fatigue. Reductions in LACP-Sp and LACP-Max for bulbar speakers might reflect tongue weakness. Although confirmation of results is needed, the data indicate that individuals with high word intelligibility maintained LACP-Sp at or above 2 kPa and LACP-Max at or above 50 kPa.

    Full Text Available We present the magnetic resonance (MR findings of five patients with amyotrophic lateral sclerosis (ALS using a spin-echo sequence with an additional magnetization transfer (MT pulse on T1-weighted images (T1 SE/MT. These findings were absent in the control group and consisted of hyperintensity of the corticospinal tract. Moreover we discuss the principles and the use of this fast but simple MR technique in the diagnosis of ALS

  16. Sleep quality in long-term survivors of head and neck cancer: preliminary findings. (United States)

    Li, Na; Otomaru, Takafumi; Taniguchi, Hisashi


    This preliminary study evaluated sleep quality in long-term head and neck cancer survivors, using demographic data and clinical features of the cancers as assessment criteria. In addition, a possible correlation was examined between scores on self-rated questionnaires of sleep quality and assessments of quality of life and oral health status. Subjects were 77 head and neck cancer survivors. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. Oral and general health status was assessed using The Oral Health Impact Profile (OHIP-14) and the Short-Form Health Survey (SF-36), respectively, and correlated with clinical parameters. Spearman's correlation coefficients were calculated to examine relationships between variables. Logistic regression analysis was performed to identify independent variables associated with poor sleep quality. Eighty-three percent of patients had poor sleep quality (global scores ≥5) and 40% had a global Pittsburgh Sleep Quality Index score ≥8, indicating significantly poor sleep quality. Nocturnal enuresis, daytime sleepiness, and early morning awakening were the most common complaints. Extensive neck dissection, a lower SF-36 mental component score, and a higher OHIP-14 psychological disability score were independently associated with poor sleep quality. OHIP-14 global score was linked independently with daytime sleepiness. This is the first study to demonstrate a high prevalence of poor sleep quality in long-term head and neck cancer survivors. Extensive neck dissection, poor mental health, and psychological disability may contribute to poor sleep quality. Maintaining good oral health-related quality of life could promote better sleep in these patients.

  17. Leukocyte telomere length in major depression: correlations with chronicity, inflammation and oxidative stress--preliminary findings.

    Directory of Open Access Journals (Sweden)

    Owen M Wolkowitz


    Full Text Available Depression is associated with an unusually high rate of aging-related illnesses and early mortality. One aspect of "accelerated aging" in depression may be shortened leukocyte telomeres. When telomeres critically shorten, as often occurs with repeated mitoses or in response to oxidation and inflammation, cells may die. Indeed, leukocyte telomere shortening predicts early mortality and medical illnesses in non-depressed populations. We sought to determine if leukocyte telomeres are shortened in Major Depressive Disorder (MDD, whether this is a function of lifetime depression exposure and whether this is related to putative mediators, oxidation and inflammation.Leukocyte telomere length was compared between 18 unmedicated MDD subjects and 17 controls and was correlated with lifetime depression chronicity and peripheral markers of oxidation (F2-isoprostane/Vitamin C ratio and inflammation (IL-6. Analyses were controlled for age and sex.The depressed group, as a whole, did not differ from the controls in telomere length. However, telomere length was significantly inversely correlated with lifetime depression exposure, even after controlling for age (p<0.05. Average telomere length in the depressed subjects who were above the median of lifetime depression exposure (≥9.2 years' cumulative duration was 281 base pairs shorter than that in controls (p<0.05, corresponding to approximately seven years of "accelerated cell aging." Telomere length was inversely correlated with oxidative stress in the depressed subjects (p<0.01 and in the controls (p<0.05 and with inflammation in the depressed subjects (p<0.05.These preliminary data indicate that accelerated aging at the level of leukocyte telomeres is proportional to lifetime exposure to MDD. This might be related to cumulative exposure to oxidative stress and inflammation in MDD. This suggest that telomere shortening does not antedate depression and is not an intrinsic feature. Rather, telomere shortening

  18. Neuro emotional technique effects on brain physiology in cancer patients with traumatic stress symptoms: preliminary findings. (United States)

    Monti, Daniel A; Tobia, Anna; Stoner, Marie; Wintering, Nancy; Matthews, Michael; He, Xiao-Song; Doucet, Gaelle; Chervoneva, Inna; Tracy, Joseph I; Newberg, Andrew B


    The purpose of this study was to characterize the neurophysiological and clinical effects that may result from the neuro emotional technique (NET) in patients with traumatic stress symptoms associated with a cancer-related event. We hypothesized that self-regulatory processing of traumatic memories would be observable as physiological changes in key brain areas after undergoing the NET intervention and that these changes would be associated with improvement of traumatic stress symptoms. We enrolled 23 participants with a prior cancer diagnosis who expressed a distressing cancer-related memory that was associated with traumatic stress symptoms of at least 6 months in duration. Participants were randomized to either the NET intervention or a waitlist control condition. To evaluate the primary outcome of neurophysiological effects, all participants received functional magnetic resonance imaging (fMRI) during the auditory presentation of both a neutral stimulus and a description of the specific traumatic event. Pre/post-comparisons were performed between the traumatic and neutral condition, within and between groups. Psychological measures included the Impact of Event Scale (IES), State Trait Anxiety Index (STAI), Brief Symptom Inventory (BSI)-18, and Posttraumatic Cognitions Inventory (PTCI). The initial fMRI scans in both groups showed significant increases in the bilateral parahippocampus and brainstem. After NET, reactivity in the parahippocampus, brainstem, anterior cingulate, and insula was significantly decreased during the traumatic stimulus. Likewise, participants receiving the NET intervention had significant reductions (p brain regions involved with traumatic memories and distress such as the brainstem, insula, anterior cingulate gyrus, and parahippocampus had significantly reduced activity after the NET intervention and were associated with clinical improvement of symptoms associated with distressing recollections. This preliminary study suggests that the

  19. Small Cages with Insect Couples Provide a Simple Method for a Preliminary Assessment of Mating Disruption

    Directory of Open Access Journals (Sweden)

    Françoise Briand


    Full Text Available Mating disruption by sex pheromones is a sustainable, effective and widely used pest management scheme. A drawback of this technique is its challenging assessment of effectiveness in the field (e.g., spatial scale, pest density. The aim of this work was to facilitate the evaluation of field-deployed pheromone dispensers. We tested the suitability of small insect field cages for a pre-evaluation of the impact of sex pheromones on mating using the grape moths Eupoecilia ambiguella and Lobesia botrana, two major pests in vineyards. Cages consisted of a cubic metal frame of 35 cm sides, which was covered with a mosquito net of 1500 μm mesh size. Cages were installed in the centre of pheromone-treated and untreated vineyards. In several trials, 1 to 20 couples of grape moths per cage were released for one to three nights. The proportion of mated females was between 15 to 70% lower in pheromone-treated compared to untreated vineyards. Overall, the exposure of eight couples for one night was adequate for comparing different control schemes. Small cages may therefore provide a fast and cheap method to compare the effectiveness of pheromone dispensers under standardised semi-field conditions and may help predict the value of setting-up large-scale field trials.

  20. A Preliminary Assessment of Legged Mobility Provided by a Lower Limb Exoskeleton for Persons With Paraplegia (United States)

    Farris, Ryan J.; Quintero, Hugo A.; Murray, Spencer A.; Ha, Kevin H.; Hartigan, Clare; Goldfarb, Michael


    This paper presents an assessment of a lower limb exoskeleton for providing legged mobility to people with paraplegia. In particular, the paper presents a single-subject case study comparing legged locomotion using the exoskeleton to locomotion using knee–ankle–foot orthoses (KAFOs) on a subject with a T10 motor and sensory complete injury. The assessment utilizes three assessment instruments to characterize legged mobility, which are the timed up-and-go test, the Ten-Meter Walk Test (10 MWT), and the Six-Minute Walk Test (6 MWT), which collectively assess the subject’s ability to stand, walk, turn, and sit. The exertion associated with each assessment instrument was assessed using the Physiological Cost Index. Results indicate that the subject was able to perform the respective assessment instruments 25%, 70%, and 80% faster with the exoskeleton relative to the KAFOs for the timed up-and-go test, the 10 MWT, and the 6 MWT, respectively. Measurements of exertion indicate that the exoskeleton requires 1.6, 5.2, and 3.2 times less exertion than the KAFOs for each respective assessment instrument. The results indicate that the enhancement in speed and reduction in exertion are more significant during walking than during gait transitions. PMID:23797285

  2. Preliminary evidence that DEXA provides an accurate assessment of body composition. (United States)

    Kohrt, W M


    It was previously found that dual-energy X-ray absorptiometry (DEXA) underestimated central body fat. The purposes of this study were to determine whether an updated version (enhanced version 5.64) of the analysis program corrected this problem (experiment 1) and to compare body composition assessed by DEXA and hydrodensitometry (HD) in women (n = 225) and men (n = 110) across a 21- to 81-yr age range (experiment 2). For experiment 1, 10 subjects underwent DEXA procedures in a control condition and with packets of lard positioned over either the thighs or the truncal region. DEXA accurately quantified the additional mass as approximately 96% fat, regardless of position. For experiment 2, DEXA yielded higher (P fatness than did HD (32.1 +/- 12.0 vs. 31.2 +/- 10.1%). The mean difference between the two methods was similar in young, middle-aged, and older subjects, but was different in men (HD-DEXA, 1.6 +/- 3.4% of body wt) than in women (-2.1 +/- 3.8% of body wt). Correcting the density of fat-free mass for variance in the bone mineral fraction of fat-free mass reduced the difference between the methods in men from 1.6 +/- 3.4 to -0.7 +/- 2.9% but widened it in women from -2.1 +/- 3.8 to -3.5 +/- 3.4%. A second correction procedure that adjusted for variance in water, protein, and mineral fractions of fat-free mass eliminated the differences in estimates of fat content by DEXA and HD in both men (21.1 +/- 9.3 vs. 20.6 +/- 8.4%, respectively) and women (37.5 +/- 9.3 vs. 36.8 +/- 8.0%, respectively). These results provide encouraging, but not definitive, evidence that the assessment of body composition by DEXA is accurate under the specified conditions.

  3. Preliminary findings demonstrating latent effects of early adolescent marijuana use onset on cortical architecture

    Directory of Open Access Journals (Sweden)

    Francesca M. Filbey


    Conclusions: Divergent patterns between current MJ use and elements of cortical architecture were associated with early MJ use onset. Considering brain development in early adolescence, findings are consistent with disruptions in pruning. However, divergence with continued use for many years thereafter suggests altered trajectories of brain maturation during late adolescence and beyond.

    The significance of microalbuminuria (MA) in paediatric essential hypertension has yet to be established. The Leontio Lyceum ALbuminuria Study (3L Study) was designed to determine the prevalence of MA among Greek schoolchildren and to evaluate these rates in relation to the children's anthropometric and lifestyle characteristics, and dietary habits. During April 2009, 498 students from the Leontio Lyceum, aged 12-17 years (7th-12th grade), were asked to participate in the 3L Study. For each child a questionnaire was completed that was developed for the purposes of the study to retrieve information on socio-demographic and lifestyle characteristics, as well as dietary habits (through a semi-quantitative Food Frequency Questionnaire), and physical activity status. Overweight and obesity were defined using the international body mass index cut-off points established for children and young people. Office blood pressure (BP) was measured on two different occasions and those students who had BP >95th percentile for gender, age and height on both occasions were considered as hypertensives. Microalbuminuria was determined as albumin to creatinine ratio >or=22 mg/g in boys and >or=31 mg/g in girls in a morning spot urine sample using a quantitative assay (DCA 2000). The prevalence of MA was found to be 12.9% and that of childhood hypertension 5.2%. The prevalence of overweight status was 25.8% and 5.8% of the students were classified as obese. Low physical activity was reported by 7% of boys and girls, while 46.5% of the students reported participation in vigorous physical activities during a normal week. Based on the KIDMED score of each student, only 6% of them were classified as high adherers to a Mediterranean diet and 41.9% were classified as having very low diet quality. In this paper we present the aims, design and preliminary results of an epidemiological study on MA, hypertension, increased body size and lifestyle characteristics among Greek schoolchildren.

  5. Primary Care Tasks Associated with Provider Burnout: Findings from a Veterans Health Administration Survey. (United States)

    Kim, Linda Y; Rose, Danielle E; Soban, Lynn M; Stockdale, Susan E; Meredith, Lisa S; Edwards, Samuel T; Helfrich, Christian D; Rubenstein, Lisa V


    The patient-centered medical home (PCMH) is a primary care delivery model predicated on shared responsibility for patient care among members of an interprofessional team. Effective task sharing may reduce burnout among primary care providers (PCPs). However, little is known about the extent to which PCPs share these responsibilities, and which, if any, of the primary care tasks performed independently by the PCPs (vs. shared with the team) are particularly associated with PCP burnout. A better understanding of the relationship between these tasks and their effects on PCP burnout may help guide focused efforts aimed at reducing burnout. To investigate (1) the extent to which PCPs share responsibility for 14 discrete primary care tasks with other team members, and (2) which, if any, of the primary care tasks performed by the PCPs (without reliance on team members) are associated with PCP burnout. Secondary data analysis of Veterans Health Administration (VHA) survey data from two time periods. 327 providers from 23 VA primary care practices within one VHA regional network. The dependent variable was PCP report of burnout. Independent variables included PCP report of the extent to which they performed 14 discrete primary care tasks without reliance on team members; team functioning; and PCP-, clinic-, and system-level variables. In adjusted models, PCP reports of intervening on patient lifestyle factors and educating patients about disease-specific self-care activities, without reliance on their teams, were significantly associated with burnout (intervening on lifestyle: b = 4.11, 95% CI = 0.39, 7.83, p = 0.03; educating patients: b = 3.83, 95% CI = 0.33, 7.32, p = 0.03). Performing behavioral counseling and self-management education tasks without relying on other team members for assistance was associated with PCP burnout. Expanding the roles of nurses and other healthcare professionals to assume responsibility for these tasks may ease PCP burden and

    Full Text Available Introduction. The aim of this article is to discuss the relationship between affective states experienced by athletes and the outcome of their performance. The article presents the findings of a pilot study which made it possible to determine the relationship between the emotional states, mood, and level of stress of a group of pentathletes and the outcomes they achieved in a sports competition. Material and methods. The study involved 12 senior modern pentathletes, including 7 male and 5 female athletes. The following standard psychology questionnaires were used in the study: the 10-item Perceived Stress Scale (PSS-10, the Positive and Negative Affect Schedule (PANAS, and the Profile of Mood State (POMS. Performance was assessed based on the number of points achieved by the pentathletes in particular events in the pentathlon, which are held according to the rules set by the International Modern Pentathlon Union (UIPM. Results. The findings of the study confirmed that there was a correlation between the athletes’ mood and emotions and the outcome of their performance. The level of stress strongly negatively correlated with both the outcome they expected to achieve and the one they actually achieved for the combined event (running and shooting. For this event a relationship was also found between the athletes’ affective states and their outcomes: in running and shooting there was a positive and statistically significant correlation between the level of positive emotions and anger and the results achieved. However, friendliness, one of the other affective state variables that were measured, correlated negatively with the outcomes of the athletes’ performance. Conclusions. In the group of pentathletes who participated in the study, a high level of anger was associated with better outcomes, and a high level of friendliness had an adverse effect on the results achieved. The findings of the current study confirm that there is a relationship

  7. Dental and craniofacial findings in eight miniature schnauzer dogs affected by myotonia congenita: preliminary results. (United States)

    Gracis, M; Keith, D; Vite, C H


    Myotonia is a clinical sign characterized by the delay of skeletal muscle relaxation following the cessation of a voluntary activity or the termination of an electrical or mechanical stimulus. Recently, Miniature Schnauzers with myotonia congenita associated with defective chloride ion conductance across the skeletal muscle membrane were identified. Congenital myotonia in these dogs appears to follow an autosomal recessive mode of inheritance. Craniofacial and dental findings of eight Miniature Schnauzer dogs with myotonia congenita are described in the present paper. These findings include: delayed dental eruption of both deciduous and permanent dentition: persistent deciduous dentition; unerupted or partially erupted permanent teeth: crowding and rotation of premolar and or incisor teeth: missing teeth: increased interproximal space between the maxillary fourth premolar and first molar teeth: decreased interproximal space between the maxillary canine and lateral incisor teeth: inability to fully close the mouth due to malocclusion: distoclusion: and, decreased mandibular range of motion. A long narrow skull with a flattened zygomatic arch and greater mandibular body curvature were also consistent findings in the affected dogs. The small number of dogs studied prevents conclusive statements about the origin of these abnormalities, however it is interesting that only 1 of 45 unaffected Miniature Schnauzer dogs showed similar traits.

  9. Preliminary Findings of Inflight Icing Field Test to Support Icing Remote Sensing Technology Assessment (United States)

    King, Michael; Reehorst, Andrew; Serke, Dave


    NASA and the National Center for Atmospheric Research have developed an icing remote sensing technology that has demonstrated skill at detecting and classifying icing hazards in a vertical column above an instrumented ground station. This technology has recently been extended to provide volumetric coverage surrounding an airport. Building on the existing vertical pointing system, the new method for providing volumetric coverage will utilize a vertical pointing cloud radar, a multifrequency microwave radiometer with azimuth and elevation pointing, and a NEXRAD radar. The new terminal area icing remote sensing system processes the data streams from these instruments to derive temperature, liquid water content, and cloud droplet size for each examined point in space. These data are then combined to ultimately provide icing hazard classification along defined approach paths into an airport.

  10. Mindfulness-based stress reduction for people living with HIV/AIDS: preliminary review of intervention trial methodologies and findings. (United States)

    Riley, Kristen E; Kalichman, Seth


    In the context of successful antiretroviral therapy (ART) for the management of HIV infection, the harmful effects of stress remain a significant threat. Stress may increase viral replication, suppress immune response, and impede adherence to ART. Stressful living conditions of poverty, facing a chronic life-threatening illness and stigma all exacerbate chronic stress in HIV-affected populations. Stress-reduction interventions are urgently needed for the comprehensive care of people living with HIV. Mindfulness-based stress reduction (MBSR) is one approach that has shown promise as an intervention for patients facing other medical conditions for reducing disease progression, psychological distress and maladaptive behaviours. In this systematic review, we identified 11 studies that have examined MBSR as an intervention for HIV-positive populations. Of the studies, six were randomised designs, one was a quasi-experimental design, and the remaining four were pre- and post-test designs. The preliminary outcomes support MBSR to decrease emotional distress with mixed evidence for impact on disease progression. Effect sizes were generally small to moderate in magnitude. The early findings from this emerging literature must be considered preliminary and support moving forward with more rigorous controlled trials, evaluated with objective assessments in longer-term follow-ups to determine the efficacy of MBSR for people living with HIV.

  11. Deservingness to state health services for South-South migrants: a preliminary study of Costa Rican providers' views. (United States)

    Goldade, Kate; Okuyemi, Kolawole S


    Health services for undocumented migrants highlight the complex politics of the "right to health". South-South migrants, an emerging focus of migration scholarship, compose an estimated 40 percent of the world's 200 million international migrants. In Costa Rica, internationally renowned for its public health achievements, undocumented Nicaraguan migrants number between 8 and 16 percent of the population. In spite of historical, linguistic, and ethnic congruencies between peoples of the sending and receiving countries at the ends of this migratory path, access to health services is limited for migrants experiencing illegality in the global economic South. Costa Rican health providers articulated concepts of deservingness to health services for undocumented Nicaraguan migrants. This article is based on a preliminary study with a purposive sample of 22 Costa Rican health services providers. Interviewed over two field research periods (June 2005-July 2006; July, 2008), providers addressed four types of health services for undocumented migrants. Overall their views on the deservingness of health services for undocumented migrants reflected a utilitarian approach. Specifically, their talk reflected: (1) the limits to state responsibility for ensuring the health of individuals not pertaining to the nation; and (2) a concern for the threats posed to the health of Costa Rican nationals. Costa Rican providers' perceptions on health services for migrants offer partial insight for the development of future migrant health policies in receiving countries of the global economic South.

  12. Retrospective study of sonographic findings in bone involvement associated with rotator cuff calcific tendinopathy: preliminary results of a case series

    Directory of Open Access Journals (Sweden)

    Marcello H. Nogueira-Barbosa


    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

  13. Functional near infrared spectroscopy as a potential biological assessment of addiction recovery: preliminary findings. (United States)

    Dempsey, Jared P; Harris, Kitty S; Shumway, Sterling T; Kimball, Thomas G; Herrera, J Caleb; Dsauza, Cynthia M; Bradshaw, Spencer D


    Addiction science has primarily utilized self-report, continued substance use, and relapse factors to explore the process of recovery. However, the entry into successful abstinence substantially reduces our assessment abilities. Advances in neuroscience may be the key to objective understanding, treating, and monitoring long-term success in addiction recovery. To explore functional near infrared spectroscopy (fNIR) as a viable technique in the assessment of addiction-cue reactivity. Specifically, prefrontal cortex (PFC) activation to alcohol cues was explored among formally alcohol-dependent individuals, across varying levels of successful abstinence. The aim of the investigation was to identify patterns of PFC activation change consistent with duration of abstinence. A total of 15 formally alcohol-dependent individuals, with abstinence durations ranging from 1 month to 10 years, viewed alcohol images during fNIR PFC assessment. Participants also subjectively rated the same images for affect and arousal level. Subjective ratings of alcohol cues did not significantly correlate with duration of abstinence. As expected, days of abstinence did not significantly correlate with neutral cue fNIR reactivity. However, for alcohol cues, fNIR results showed increased days of abstinence was associated with decreased activation within the dorsolateral and dorsomedial prefrontal cortex regions. The present results suggest that fNIR may be a viable tool in the assessment of addiction-cue reactivity. RESULTS also support previous findings on the importance of dorsolateral and dorsomedial PFC in alcohol-cue activation. The findings build upon these past results suggesting that fNIR-assessed activation may represent a robust biological marker of successful addiction recovery.

  17. The Multiple Sclerosis Cooperative Etiological Study in Italy: preliminary analysis of CSF findings. (United States)

    Trojano, M; Logroscino, G C; Pisicchio, L; Rosato, A; Bordo, B; Citterio, A; Amato, M P; Livrea, P


    295 newly diagnosed Multiple Sclerosis (MS) patients were investigated for interdependence of CSF abnormalities: leukocyte count, CSF/serum albumin ratio, CSF IgG index and intrathecal synthesis of oligoclonal IgG. Only 7% of patients had no CSF abnormality. The most frequent abnormal finding was the presence of intrathecal synthesis of oligoclonal IgG. Polyacrylamide isoelectric focusing appeared more sensitive than agarose electrophoresis for the detection of abnormal CSF fractions. CSF IgG index had low negative and high positive predictive value when compared with electrophoretic methods. Suspected MS had the lowest frequency of abnormal CSF parameters. Patients with oligoclonal CSF bands (OB+) did not differ in age, sex, disease duration or annual bout rate from patients without oligoclonal bands (OB-). CSF leukocyte count was higher in OB+ than in OB- patients. Low CSF cell count was a hallmark of progressive disease. In OB+ patients CSF cell count correlated with CSF IgG index during the first five years of disease and declined with increasing disease duration. In later disease phases CSF IgG index correlated negatively with CSF/serum albumin ratio. 5 years follow-up of this series of patients is in progress to assess the diagnostic and prognostic values of CSF abnormalities in Multiple Sclerosis.

  18. Music evoked autobiographical memory after severe acquired brain injury: preliminary findings from a case series. (United States)

    Baird, A; Samson, S


    Music evoked autobiographical memories (MEAMs) have been characterised in the healthy population, but not, to date, in patients with acquired brain injury (ABI). Our aim was to investigate music compared with verbal evoked autobiographical memories. Five patients with severe ABI and matched controls completed the experimental music (MEAM) task (a written questionnaire) while listening to 50 "Number 1 Songs of the Year" (from 1960 to 2010). Patients also completed the Autobiographical Memory Interview (AMI) and a standard neuropsychological assessment. With the exception of Case 5, who reported no MEAMs and no autobiographical incidents on the AMI and who also had impaired pitch perception, the range of frequency and type of MEAMs in patients was broadly in keeping with their matched controls. The relative preservation of MEAMs in four cases was particularly noteworthy given their impaired verbal and/or visual anterograde memory, and in three cases, autobiographical memory impairment. The majority of MEAMs in both cases and matched controls were of a person/people or a period of life. In three patients music was more efficient at evoking autobiographical memories than the AMI verbal prompts. This is the first study of MEAMs after ABI. The findings suggest that music is an effective stimulus for eliciting autobiographical memories, and may be beneficial in the rehabilitation of autobiographical amnesia, but only in patients without a fundamental deficit in autobiographical recall memory and intact pitch perception.

  19. Effects of Brief Behavioural Activation on Approach and Avoidance Tendencies in Acute Depression: Preliminary Findings. (United States)

    Nasrin, Farjana; Rimes, Katharine; Reinecke, Andrea; Rinck, Mike; Barnhofer, Thorsten


    It has been suggested that the behavioural activation (BA) treatments for depression unfold their effects, at least partly, through changes in approach and avoidance tendencies. However, as yet, little research has examined the cognitive effects of these interventions. This study investigated the impact of a single session of BA on depressive symptomatology, self-reported avoidance, and behavioural approach and avoidance tendencies. Forty-six patients with a diagnosis of Major Depression were recruited from primary care psychological therapies services and block randomized to either a single session of behavioural activation (n = 22) or waiting list control (n = 24) delivered by an unblinded therapist. Self-reports of symptoms and cognitive factors were assessed before and after the one-week intervention phase. Approach and avoidance behavioural tendencies were assessed using the Approach-Avoidance Task (AAT). Data from 40 participants (n = 20 in each group) was available for analyses. Depressive symptoms significantly decreased, and activation significantly increased from before to after treatment in the treatment group, but not in the control group. Performance on the AAT showed a trend indicating increased approach to positive valence stimuli in the treatment group, but not in the control group. Mediational analyses indicated small indirect effects of self-reported change in activation as mediators of the effect of condition on symptoms. The findings suggest that a single session of BA can have significant effects on symptoms in clinically depressed patients. Results hint at the possibility that increased behavioural approach might mediate the effect of BA.

  20. Preliminary findings on lifetime trauma prevalence and PTSD symptoms among adolescents in Sarawak Malaysia. (United States)

    Ghazali, Siti Raudzah; Elklit, Ask; Balang, Rekaya Vincent; Sultan, M Ameenudeen; Kana, Kamarudin


    The objective of this study is to determine the prevalence of lifetime exposure to traumatic events and its relation to PTSD symptoms. Participants were randomly selected from several schools located in the city of Kuching. There were 85 adolescents participating in this study, with ages ranging from 13 to 14 years old, of whom 31% (n=26) were males and 69% (n=59) females. The Child Posttraumatic Stress Index-Revised, The Harvard Trauma Questionnaire and a lifetime trauma checklist were used in this study. Results showed that 77.6% of participants were exposed to at least one lifetime trauma. The most frequently reported traumas were road accident (20.1%), death of a family member (19.7%), and almost drowning (10%). There was more indirect trauma than direct trauma exposure. Males were more likely to be involved in traumatic events than females. Results showed that 7.1% (6) exhibited PTSD symptoms. There was no significant difference in the mean score of CPTS-RI between genders and among ethnic groups. Total exposure to traumatic events was significantly correlated with PTSD symptoms. Findings suggest that number of lifetime traumatic events was quite high and multiple exposures to traumatic events were significantly related to PTSD symptoms. Copyright © 2014 Elsevier B.V.

  1. Radiofrequency Ablation of Functioning Adrenal Adenomas: Preliminary Clinical and Laboratory Findings. (United States)

    Szejnfeld, Denis; Nunes, Thiago Franchi; Giordano, Endrigo Emanuel; Freire, Fabio; Ajzen, Sergio Aron; Kater, Claudio Elias; Goldman, Suzan Menasce


    To evaluate clinical and laboratory findings in patients undergoing radiofrequency (RF) ablation for functioning adrenal adenomas. Eleven adult patients, nine with Conn syndrome and two with Cushing syndrome, underwent percutaneous computed tomography-guided RF ablation for benign adrenal neoplasms. Systolic, diastolic, and mean blood pressure and the number of classes of antihypertensive drugs used by each patient were analyzed before and 1, 4, and 12 weeks after the procedure. Serum hormone levels were analyzed within 30 days before and 12 weeks after the procedure. Of the nine patients with Conn syndrome, eight showed normal serum aldosterone levels after the procedure and one patient had a nodule located very close to the inferior vena cava, resulting in incomplete ablation. The two patients with Cushing syndrome had normal serum and salivary cortisol levels after the procedure. Mean aldosterone concentration at baseline was 63.3 ng/dL ± 28.0 and decreased to 13.3 ng/dL ± 13.5 at 12 weeks postoperatively (P = .008). Systolic, diastolic, and mean blood pressures decreased significantly in the first week after the procedure (P < .001) and remained stable during further follow-up. In patients with Conn syndrome or Cushing syndrome, percutaneous RF ablation of functioning adrenal adenomas may result in normalization of hormone secretion, improvement in blood pressure, and reduced need for antihypertensive drugs.

    Saba, Luca; Berritto, Daniela; Iacobellis, Francesca; Scaglione, Mariano; Castaldo, Sigismondo; Cozzolino, Santolo; Mazzei, Maria Antonietta; Di Mizio, Veronica; Grassi, Roberto


    AIM: To explore the physiopathology and magnetic resonance imaging (MRI) findings in an animal model of acute arterial mesenteric ischemia (AAMI) with and without reperfusion. METHODS: In this study, 8 adult Sprague-Dawley rats underwent superior mesenteric artery (SMA) ligation and were then randomly divided in two groups of 4. In group I, the ischemia was maintained for 8 h. In group II, 1-h after SMA occlusion, the ligation was removed by cutting the thread fixed on the back of the animal, and reperfusion was monitored for 8 h. MRI was performed using a 7-T system. RESULTS: We found that, in the case of AAMI without reperfusion, spastic reflex ileus, hypotonic reflex ileus, free abdominal fluid and bowel wall thinning are present from the second hour, and bowel wall hyperintensity in T2-W sequences are present from the fourth hour. The reperfusion model shows the presence of early bowel wall hyperintensity in T2-W sequences after 1 h and bowel wall thickening from the second hour. CONCLUSION: Our study has shown that MRI can assess pathological changes that occur in the small bowel and distinguish between the presence and absence of reperfusion after induced acute arterial ischemia.

  3. High-resolution diffusion tensor imaging of human patellar cartilage: feasibility and preliminary findings. (United States)

    Filidoro, L; Dietrich, O; Weber, J; Rauch, E; Oerther, T; Wick, M; Reiser, M F; Glaser, C


    MR diffusion tensor imaging (DTI) was used to analyze the microstructural properties of articular cartilage. Human patellar cartilage-on-bone samples were imaged at 9.4T using a diffusion-weighted SE sequence (12 gradient directions, resolution = 39 x 78 x 1500 microm(3)). Voxel-based maps of the mean diffusivity, fractional anisotropy (FA), and eigenvectors were calculated. The mean diffusivity decreased from the surface (1.45 x 10(-3) mm(2)/s) to the tide mark (0.68 x 10(-3) mm(2)/s). The FA was low (0.04-0.28) and had local maxima near the surface and in the portion of the cartilage corresponding to the radial layer. The eigenvector corresponding to the largest eigenvalue showed a distinct zonal pattern, being oriented tangentially and radially in the upper and lower portions of the cartilage, respectively. The findings correspond to current scanning electron microscopy (SEM) data on the zonal architecture of cartilage. The eigenvector maps appear to reflect the alignment of the collagenous fibers in cartilage. In view of current efforts to develop and evaluate structure-modifying therapeutic approaches in osteoarthritis (OA), DTI may offer a tool to assess the structural properties of cartilage.

  4. Risk factors for colorectal cancer in man induce aberrant crypt foci in rats: Preliminary findings. (United States)

    Yang, Kai; Fard, Sara; Furrer, Rudolf; Archer, Michael C; Bruce, W Robert; Lip, HoYin; Mehta, Rhea; O'Brien, Peter J; Giacca, Adria; Ward, Wendy E; Femia, A Pietro; Caderni, Giovanna; Medline, Alan; Banks, Kate


    Epidemiological studies have demonstrated clear associations between specific dietary and environmental risk factors and incidence of colorectal cancer, but the mechanisms responsible for these associations are not known. An animal model could facilitate such an understanding. Both genotoxic and nongenotoxic carcinogens induce aberrant crypt foci (ACF) in the colons of F344 rats. F344 rats were provided with diets that contained putative risk factors for CRC: low calcium and low vitamin D, high iron, high fructose, and decreased light (UV) exposure or a control diet for 14 wk. The rats were then assessed with biochemical measures and by topological examination for evidence of colon abnormalities. Circulating ionized calcium was decreased from 2.85 to 1.69 mmol/L, and ACF were increased from 0.7 to 13.6 lesions/colon (both P < 0.001). Rats exposed to the multiple environmental conditions associated with colon cancer, developed ACF similar to the heterogeneous or ill-defined ACF in the human colon. Heterogeneous ACF are the most frequently seen in humans and are also seen in rats shortly after exposure to the non-genotoxic colon carcinogen, dextransulfate sodium. The rodent model could be used to assess the pathways from diet and environment to colon cancer and to provide guidance for clinical studies.

  5. Preliminary clinical findings on NEUMUNE as a potential treatment for acute radiation syndrome

    5-androstenediol (5-AED) has been advanced as a possible countermeasure for treating the haematological component of acute radiation syndrome (ARS). It has been used in animal models to stimulate both innate and adaptive immunity and treat infection and radiation-induced immune suppression. We here report on the safety, tolerability and haematologic activity of 5-AED in four double-blinded, randomized, placebo-controlled studies on healthy adults including elderly subjects. A 5-AED injectable suspension formulation (NEUMUNE) or placebo was administered intramuscularly as either a single injection, or once daily for five consecutive days at doses of 50, 100, 200 or 400 mg. Subjects (n = 129) were randomized to receive NEUMUNE (n = 95) or the placebo (n = 34). NEUMUNE was generally well-tolerated; the most frequent adverse events were local injection site reactions (n = 104, 81%) that were transient, dose-volume dependent, mild to moderate in severity, and that resolved over the course of the study. Blood chemistries revealed a transient increase (up to 28%) in creatine phosphokinase and C-reactive protein levels consistent with intramuscular injection and injection site irritation. The blood concentration profile of 5-AED is consistent with a depot formulation that increases in disproportionate increments following each dose. NEUMUNE significantly increased circulating neutrophils (p < 0.001) and platelets (p < 0.001) in the peripheral blood of adult and elderly subjects. A dose-response relationship was identified. Findings suggest that parenteral administration of 5-AED in aqueous suspension may be a safe and effective means to stimulate innate immunity and alleviate neutropenia and thrombocytopenia associated with ARS.

    Full Text Available Background: The study examined the prevalence of trauma and posttraumatic stress disorder (PTSD symptoms among community dwelling Chinese adults in Hong Kong. The relationship of traumatic life events (including loss and mental health has been investigated. Methods: The sampling of the collaborative study (HKMMS: Hong Kong Mental Morbidity Survey adopts a multi-stage stratification approach with the distribution of residential premises in different geographical districts and the relative proportion of private versus public housing units taken into consideration. In Phase I of this study, 4,644 adults were screened for PTSD with the Trauma Screening Questionnaire (TSQ and Life Event Checklist (LEC, Beck's scales and CIS-R (Revised Clinical Interview Schedule. In Phase II of the study, clinical psychologists conducted the Structured Clinical Interview for DSM Disorders (SCID for 92 participants (results not reported here. Results: Among Phase I participants, 65% reported traumatic experience (including 18% who reported personal experience of sudden death of significant others. Age and gender make a difference in traumatic experience. When compared to participants who reported no traumatic experience in the past, participants who reported to have personal experience of sudden death of significant others or other traumatic experiences were found to have higher TSQ scores, higher psychological distress, lower social support (PSS: Multidimensional Scale of Perceived Social Support, and lower life functioning (SOFAS: Social and Occupational Functioning Assessment Scale, p<0.001. Findings of hierarchical regression showed that type of trauma (i.e., loss, other trauma, or no trauma contributed significantly to the prediction of all the mental health indices after demographic and social variables were controlled. Conclusions: Public education on the association of traumatic experience and psychological health, as well as the monitoring of mental health

    Objective: The diagnosis of acute pyelonephritis in children remains a clinical challenge. It may cause permanent renal scar formation and results in the chronic renal failure if prompt diagnosis and treatment are delayed. The purpose of this study is to compare magnetic resonance imaging (MRI) and renal cortical scintigraphy (RCS) findings in childhood acute pyelonephritis and to determine pyelonephritic foci in the acute phase. Materials and method: Twenty children (15 females and five males) with symptoms dysuria, enuresis, costovertebral pain, fever of 37.5 degree sign C or more and/or positive urine culture were imaged by unenhanced turbo spin echo T2, spin echo T1-weighted, pre- and post-gadolinium inversion recovery MRI and RCS. Both imaging techniques were read independently by two radiologists and nuclear medicine specialists. Sensitivity and specificity of MRI in detecting acute pyelonephritic foci and scar lesions were calculated. Furthermore, in order to calculate the reliability of MRI over RCS in differentiating scar tissue and acute pyelonephritic foci, follow-up MRI studies were done in six patients after treatment of acute pyelonephritis. Results: Sensitivity and specificity of MRI in the detection of pyelonephritic lesions were found to be 90.9 and 88.8%, respectively. There is no statistically significant difference in lesion detection between the two diagnostic modalities (P>0.05). Conclusion: Post-gadolinium MR images show significant correlation with RCS in the determination of renal pathology. Moreover, the ability of discriminating acute pyelonephritic foci and renal scar in early stages of disease is the superiority of MRI.

  8. Facial Expressiveness in Infants With and Without Craniofacial Microsomia: Preliminary Findings. (United States)

    Hammal, Zakia; Cohn, Jeffrey F; Wallace, Erin R; Heike, Carrie L; Birgfeld, Craig B; Oster, Harriet; Speltz, Matthew L


    To compare facial expressiveness (FE) of infants with and without craniofacial macrosomia (cases and controls, respectively) and to compare phenotypic variation among cases in relation to FE. Positive and negative affect was elicited in response to standardized emotion inductions, video recorded, and manually coded from video using the Facial Action Coding System for Infants and Young Children. Five craniofacial centers: Children's Hospital of Los Angeles, Children's Hospital of Philadelphia, Seattle Children's Hospital, University of Illinois-Chicago, and University of North Carolina-Chapel Hill. Eighty ethnically diverse 12- to 14-month-old infants. FE was measured on a frame-by-frame basis as the sum of 9 observed facial action units (AUs) representative of positive and negative affect. FE differed between conditions intended to elicit positive and negative affect (95% confidence interval = 0.09-0.66, P = .01). FE failed to differ between cases and controls (ES = -0.16 to -0.02, P = .47 to .92). Among cases, those with and without mandibular hypoplasia showed similar levels of FE (ES = -0.38 to 0.54, P = .10 to .66). FE varied between positive and negative affect, and cases and controls responded similarly. Null findings for case/control differences may be attributable to a lower than anticipated prevalence of nerve palsy among cases, the selection of AUs, or the use of manual coding. In future research, we will reexamine group differences using an automated, computer vision approach that can cover a broader range of facial movements and their dynamics.

    Johnson, Kia N.; Karrass, Jan; Conture, Edward G.; Walden, Tedra


    The purpose of this study was to investigate whether variations in disfluencies of young children who do (CWS) and do not stutter (CWNS) significantly change their talker group classification or diagnosis from stutterer to nonstutterer, and vice versa. Participants consisted of 17 3- to 5-year-old CWS and 9 3- to 5-year-old CWNS, with no statistically significant between-group difference in chronological age (CWS: M = 45.53 months, SD = 8.32; CWNS: M = 47.67 months, SD = 6.69). All participants had speech, language, and hearing development within normal limits, with the exception of stuttering for CWS. Both talker groups participated in a series of speaking samples that varied by: (a) conversational partner [parent and clinician], (b) location [home and clinic], and (c) context [conversation and narrative]. The primary dependent measures for this study were the number of stuttering-like disfluencies (SLD) per total number of spoken words [%SLD] and the ratio of SLD to total disfluencies (TD) [SLD/TD]. Results indicated that significant variability of stuttering did not exist as a result of conversational partner or location. Changes in context, however, did impact the CWS, who demonstrated higher SLD/TD in the conversation sample versus a narrative sample. Consistent with hypotheses, CWS and CWNS were accurately identified as stutterers and nonstutterers, respectively, regardless of changes to conversational partner, location or context for the overall participant sample. Present findings were taken to suggest that during assessment, variations in stuttering frequency resulting from changes in conversational partner, location or context do not significantly influence the diagnosis of stuttering, especially for children not on the talker group classification borderline between CWS and CWNS.

  10. A Stress Management Program for Higher Risk Medical Students: Preliminary Findings. (United States)

    Brennan, Julie; McGrady, Angele; Lynch, Denis J; Schaefer, Paul; Whearty, Kary


    Approximately 10 % of first year medical students have clinically relevant anxiety or depression which may affect academic success and quality of life. This study tested the effects of a stress management intervention on indicators of anxiety, depression and self-efficacy in self-selected first year medical students. Forty two medical students volunteered to participate and provided informed consent. An eight session intervention was offered and focused on building relaxation skills, adaptive coping, and basic nutrition. Anxiety, depression, and self-efficacy were assessed pre and post intervention. This group of students had significantly higher baseline values of depression and anxiety but lower self-efficacy compared to a previous study of medical students at the same institution (p students were at risk for later clinical syndromes. Intervention directed to decreasing the effects of stress was associated with improvement in indicators of distress and may modify the longer term risk.

  11. Urban Form Energy Use and Emissions in China: Preliminary Findings and Model Proof of Concept

    Energy Technology Data Exchange (ETDEWEB)

    Aden, Nathaniel; Qin, Yining; Fridley, David


    Urbanization is reshaping China's economy, society, and energy system. Between 1990 and 2008 China added more than 300 million new urban residents, bringing the total urbanization rate to 46%. The ongoing population shift is spurring energy demand for new construction, as well as additional residential use with the replacement of rural biomass by urban commercial energy services. This project developed a modeling tool to quantify the full energy consequences of a particular form of urban residential development in order to identify energy- and carbon-efficient modes of neighborhood-level development and help mitigate resource and environmental implications of swelling cities. LBNL developed an integrated modeling tool that combines process-based lifecycle assessment with agent-based building operational energy use, personal transport, and consumption modeling. The lifecycle assessment approach was used to quantify energy and carbon emissions embodied in building materials production, construction, maintenance, and demolition. To provide more comprehensive analysis, LBNL developed an agent-based model as described below. The model was applied to LuJing, a residential development in Jinan, Shandong Province, to provide a case study and model proof of concept. This study produced results data that are unique by virtue of their scale, scope and type. Whereas most existing literature focuses on building-, city-, or national-level analysis, this study covers multi-building neighborhood-scale development. Likewise, while most existing studies focus exclusively on building operational energy use, this study also includes embodied energy related to personal consumption and buildings. Within the boundaries of this analysis, food is the single largest category of the building energy footprint, accounting for 23% of the total. On a policy level, the LCA approach can be useful for quantifying the energy and environmental benefits of longer average building lifespans. In

    Increasing cases of diabetes, a general lack of routinely operational prevention, and a long history of separating disease prevention and treatment call for immediate engagement of frontier clinicians. This applies especially to village doctors who work in rural China where the majority of the nation's vast population lives. This study aims to develop and test an online Smart Web Aid for Preventing Type 2 Diabetes (SWAP-DM2) capable of addressing major barriers to applying proven interventions and integrating diabetes prevention into routine medical care. Development of SWAP-DM2 used evolutionary prototyping. The design of the initial system was followed by refinement cycles featuring dynamic interaction between development of practical and effective standardized operation procedures (SOPs) for diabetes prevention and Web-based assistance for implementing the SOPs. The resulting SOPs incorporated proven diabetes prevention practices in a synergetic way. SWAP-DM2 provided support to village doctors ranging from simple educational webpages and record maintenance to relatively sophisticated risk scoring and personalized counseling. Evaluation of SWAP-DM2 used data collected at baseline and 6-month follow-up assessment: (1) audio recordings of service encounters; (2) structured exit surveys of patients' knowledge, self-efficacy, and satisfaction; (3) measurement of fasting glucose, body mass index, and blood pressure; and (4) qualitative interviews with doctors and patients. Data analysis included (1) descriptive statistics of patients who received SWAP-DM2-assisted prevention and those newly diagnosed with prediabetes and diabetes; (2) comparison of the variables assessed between baseline and follow-up assessment; and (3) narratives of qualitative data. The 17 participating village doctors identified 2219 patients with elevated diabetes risk. Of these, 84.85% (1885/2219) consented to a fasting glucose test with 1022 new prediabetes and 113 new diabetes diagnoses made

  13. Brazilian Portuguese adaptation of Dyslexia Early Screening Test - Second edition: preliminary findings. (United States)

    Matta, Tatiana Ribeiro Gomes da; Befi-Lopes, Debora Maria


    The assessment of language skills in early childhood can provide important information about the future of literacy and academic performances. Children with reading difficulties should be identified early in their education, before they suffer from shortcomings and experience failures and feel discouraged at school. Considering the importance of early identification of language disorders and the shortage of standardized instruments for the Brazilian scenario, the overall objective of this study was to translate and adapt the Dyslexia Early Screening Test - Second Edition (DEST-2) to, subsequently, verify its applicability and efficacy in preschoolers who had Brazilian Portuguese as their native language. The study was composed of 20 children of both genders, regularly enrolled in a public school in the metropolitan region of São Paulo, none had any complaints related to learning and no indicators of sensory, neurological, cognitive, or behavioral disorders. It was observed that there was no need for significant changes to the original structure of the DEST-2 or in their administration instructions format. The performance of the children in the translated and in the national exams that were used as a benchmark was compatible, suggesting that the adjustments made met the equivalences needed to utilize this instrument with Brazilian children. A randomized study that will complement the preliminarily data obtained is in progress. Taking into consideration the linguistic and cultural diversity of Brazil, it is imperative that the translated version of the DEST-2 can be applied on a large scale and in several states of the country, in order to allow the use of this instrument as a language assessment tool in Brazil.

  17. Finding a Trans-Affirmative Provider: Challenges Faced by Trans and Gender Diverse Psychologists and Psychology Trainees. (United States)

    Dickey, Lore M; Singh, Anneliese A


    This article explores some of the challenges faced by trans and gender diverse (TGD) individuals who not only are attempting to access trans-affirmative care, but who are also members of the very profession from which they are seeking services. The authors explore challenges related to finding supervision, accessing care for assessment services, and finding a provider for personal counseling. With each example, the authors unpack the challenges and also address the implications for training for all involved. Based on these challenges that TGD psychologists and trainees face in attempting to access care, the authors provide recommendations related to trans-affirmative training for psychologists. © 2017 Wiley Periodicals, Inc.

  18. Influence of age and gender in response to {gamma}-radiation in Portuguese individuals using chromosomal aberration assay - Preliminary findings

    Cytogenetic indicators are widely used in radiobiology to evaluate effects of ionizing radiation since dicentric chromosomes (Dic) are almost exclusively induced by ionizing radiation, and spontaneous frequency of Dic is very low in the healthy general population (about one Dic per 1000 cells). A particular interest of biodosimetry has been not only to obtain absorbed dose estimates using adequate calibration curves, under the assumption that all individuals respond equally to radiation-induced chromosome aberrations, but also to find a way to demonstrate inter-individual radiosensitivity and a possible correlation with age and gender. Thus, the objective of this preliminary work was the evaluation of the influence of age and gender on the outcome of cytogenetic biomarkers after {gamma}-irradiation. Samples of peripheral blood lymphocytes from six healthy, non-smoker, donors from both genders (three men and three women), in the range of 20 to 49 years, were irradiated with doses from 0 Gy to 3 Gy air kerma, using a {sup 60}Co gamma rays source with a dose rate from 170-180 mGy/min. A clear dose-dependent increase in terms of aberrant cells excluding gaps (ACEG) and Dic was observed for all donors. Our preliminary results suggest, in the higher dose level evaluated (3 Gy), a larger intervariability among individuals for Dic, with females apparently more sensitive than males (P<0.05). Considering the different age groups, male donors showed a decrease, with age, for Dic and ACEG at the higher dose and also, for the background level, in case of ACEG. Future work will consider the study of more individuals, from both genders and different ages, in order to verify if this tendency persists and to enable the implementation of a dose-response calibration curve at Instituto Tecnologico e Nuclear for the Portuguese population, to quantify the biological dose in case of a radiological accident or emergency.

  19. Brief report: changes in brain function during acute cannabis intoxication: preliminary findings suggest a mechanism for cannabis-induced violence. (United States)

    Howard, Richard C; Menkes, David B


    Recent evidence suggests that cannabis use may be associated with antisocial and violent behaviour, raising the question: What brain mechanisms mediate the disinhibiting effects of cannabis on behaviour? To examine whether an electrocortical measure of affective impulsivity, Go/No Go contingent negative variation, is affected by acute cannabis intoxication. Slow brain potentials were recorded in a Go/No Go noise avoidance task from five habitual cannabis users before, during and after they smoked a cannabis reefer containing 11 mg D-9-tetrahydrocannabinol. Slow brain potentials developed normally in both Go and No Go conditions before and during cannabis smoking but were severely disrupted 20-40 minutes later, coincident with peak intoxication. Cannabis effects on Go/No Go brain activity resembled those reported to occur in patients with lateral prefrontal cortex lesions. Our findings are preliminary, calling for larger-scale studies, to confirm the present findings and to investigate whether brain responses to cannabis intoxication differentiate those who are predisposed to suffer adverse consequences of cannabis use from those who are not.

  20. Can typical US home visits affect infant attachment? Preliminary findings from a randomized trial of Healthy Families Durham. (United States)

    Berlin, Lisa J; Martoccio, Tiffany L; Appleyard Carmody, Karen; Goodman, W Benjamin; O'Donnell, Karen; Williams, Janis; Murphy, Robert A; Dodge, Kenneth A


    US government-funded early home visiting services are expanding significantly. The most widely implemented home visiting models target at-risk new mothers and their infants. Such home visiting programs typically aim to support infant-parent relationships; yet, such programs' effects on infant attachment quality per se are as yet untested. Given these programs' aims, and the crucial role of early attachments in human development, it is important to understand attachment processes in home visited families. The current, preliminary study examined 94 high-risk mother-infant dyads participating in a randomized evaluation of the Healthy Families Durham (HFD) home visiting program. We tested (a) infant attachment security and disorganization as predictors of toddler behavior problems and (b) program effects on attachment security and disorganization. We found that (a) infant attachment disorganization (but not security) predicted toddler behavior problems and (b) participation in HFD did not significantly affect infant attachment security or disorganization. Findings are discussed in terms of the potential for attachment-specific interventions to enhance the typical array of home visiting services.

  1. Double-blind study of alprazolam, diazepam, clonidine, and placebo in the alcohol withdrawal syndrome: preliminary findings. (United States)

    Adinoff, B


    Both a reduction in the inhibitory effects of GABA (disinhibition) and activation of the sympathetic nervous system are manifested during the alcohol withdrawal syndrome. This study was designed to explore the relative efficacy of medications that differentially affects these two biological systems: the benzodiazepines, which attenuate GABAergic disinhibition, and the alpha 2-adrenergic receptor agonists, which decrease sympathetic activation. The benzodiazepine diazepam (n = 6), the alpha 2-receptor agonist clonidine (n = 7), the benzodiazepine alprazolam (this is also purported to have alpha 2-receptor agonist properties) (n = 6), and placebo (n = 6) were evaluated in their effectiveness in decreasing signs and symptoms of alcohol withdrawal. Drug-free, alcohol-dependent patients were administered 1 of the 4 medications in a double-blind design until symptoms of withdrawal, as measured by the Clinical Instrument Withdrawal Assessment for Alcohol-Revised, were successfully treated. Alprazolam was significantly more efficacious than both clonidine and placebo in decreasing withdrawal symptoms. Diazepam was more effective than clonidine and placebo on some measures of withdrawal. Clonidine decreased systolic blood pressure significantly more than the other two active drugs and placebo, but was no more effective than placebo in decreasing other symptoms of withdrawal. Alprazolam did not significantly decrease blood pressure compared with diazepam or placebo. Despite the small sample size, these preliminary findings suggest that the efficacy of alprazolam in the treatment of alcohol withdrawal is related to its effect at the benzodiazepine receptor and not its alpha 2-receptor agonist properties.

  2. Lung function in adults following in utero and childhood exposure to arsenic in drinking water: preliminary findings. (United States)

    Dauphiné, David C; Ferreccio, Catterina; Guntur, Sandeep; Yuan, Yan; Hammond, S Katharine; Balmes, John; Smith, Allan H; Steinmaus, Craig


    Evidence suggests that arsenic in drinking water causes non-malignant lung disease, but nearly all data concern exposed adults. The desert city of Antofagasta (population 257,976) in northern Chile had high concentrations of arsenic in drinking water (>800 μg/l) from 1958 until 1970, when a new treatment plant was installed. This scenario, with its large population, distinct period of high exposure, and accurate data on past exposure, is virtually unprecedented in environmental epidemiology. We conducted a pilot study on early-life arsenic exposure and long-term lung function. We present these preliminary findings because of the magnitude of the effects observed. We recruited a convenience sample consisting primarily of nursing school employees in Antofagasta and Arica, a city with low drinking water arsenic. Lung function and respiratory symptoms in 32 adults exposed to >800 μg/l arsenic before age 10 were compared to 65 adults without high early-life exposure. Early-life arsenic exposure was associated with 11.5% lower forced expiratory volume in 1 s (FEV(1)) (P = 0.04), 12.2% lower forced vital capacity (FVC) (P = 0.04), and increased breathlessness (prevalence odds ratio = 5.94, 95% confidence interval 1.36-26.0). Exposure-response relationships between early-life arsenic concentration and adult FEV(1) and FVC were also identified (P trend = 0.03). Early-life exposure to arsenic in drinking water may have irreversible respiratory effects of a magnitude similar to smoking throughout adulthood. Given the small study size and non-random recruitment methods, further research is needed to confirm these findings.

    Yam, Kevin Kei Nang; Lo, William Tak Lam; Chiu, Rose Lai Ping; Lau, Bien Shuk Yin; Lau, Charles Ka Shing; Wu, Jen Kei Yu; Wan, Siu Man


    The present study reviews the delivery of a pilot curriculum-mentorship-based peer vocational support workers training in a Hong Kong public psychiatric hospital. The present paper reports (1) on the development of a peer vocational support workers training - Job Buddies Training Program (JBTP) in Hong Kong; and (2) preliminary findings from both quantitative and qualitative perspectives. The curriculum consists of 15-session coursework, 8-session storytelling workshop and 50-hour practicum to provide Supported Employment Peer Service (SEPS) under the mentorship of occupational therapists. Six trainees were assessed using three psychosocial assessments and qualitative methods. Compared to the baseline, the Job Buddies (JB) trainees showed an increase in awareness of their own recovery progress, occupational competence and problem-solving skills at the end of the training. Their perceived level of self-stigma was also lessened. In post-training evaluation, all Job Buddies trainees said they perceived positive personal growth and discovered their own strengths. They also appreciated the help from their mentors and gained mutual support from other trainees and from exposure with various mini-projects in the training. This pilot study provides an example of incorporating peer support and manualized training into existing work rehabilitation service for our JB trainees. Further studies on the effectiveness of service provided by peer support workers and for development on the potential use of peer support workers in other clinical and rehabilitation settings with larger subjects will be fruitful.

  4. Improving the United States airline industry's capacity to provide safe and dignified services to travelers with disabilities: focus group findings. (United States)

    McCarthy, Michael J


    As a component of a training development project for intercity air travel providers, we investigated the capacity of the airline industry to meet the needs of travelers with disabilities by exploring: (1) the level of sensitivity among personnel to travelers' needs, (2) training currently provided, (3) areas in which additional training might be beneficial, and (4) organisational/systems-level commitment to dignified assistance to all travelers. Forty-four airline/vendor employees participated in nine focus groups in four US cities. Groups were audio recorded and transcribed. A grounded-theory approach was used to develop a coding system which was then applied to transcripts to identify themes. Factors influencing capacity grouped broadly into four areas: characteristics of the job/system, characteristics of current training, characteristics of providers themselves, and characteristics of travelers. At an interpersonal level, providers were empathetic and desired to provide dignified services. They lacked training and adequate equipment in some cases, however, and organisational commitment varied between companies. Traveler characteristics were also shown to impact service delivery. Results are promising but additional regulatory and organisational policies are needed to ensure quality services. Providers and consumers of intercity air travel services may benefit from the findings and recommendations of this study.

    to quantify to what extent evidence-based health behaviour topics relevant for pregnancy are discussed with clients during midwife-led prenatal booking visits and to assess the association of client characteristics with the extent of information provided. quantitative video analyses. 173 video recordings of prenatal booking visits with primary care midwives and clients in the Netherlands taking place between August 2010 and April 2011. thirteen topics regarding toxic substances, nutrition, maternal weight, supplements, and health promoting activities were categorized as either 'never mentioned', 'briefly mentioned', 'basically explained' or 'extensively explained'. Rates on the extent of information provided were calculated for each topic and relationships between client characteristics and dichotomous outcomes of the extent of information provided were assessed using Generalized Linear Mixed Modelling. our findings showed that women who did not take folic acid supplementation, who smoked, or had a partner who smoked, were usually provided basic and occasionally extensive explanations about these topics. The majority of clients were provided with no information on recommended weight gain (91.9%), fish promotion (90.8%), caffeine limitation (89.6%), vitamin D supplementation (87.3%), physical activity promotion (81.5%) and antenatal class attendance (75.7%) and only brief mention of alcohol (91.3%), smoking (81.5%), folic acid (58.4) and weight at the start of pregnancy (52.0%). The importance of a nutritious diet was generally either never mentioned (38.2%) or briefly mentioned (45.1%). Nulliparous women were typically given more information on most topics than multiparous women. although additional information was generally provided about folic acid and smoking, when relevant for their clients, the majority of women were provided with little or no information about the other health behaviours examined in this study. Midwives may be able to improve prenatal health

  6. Effects of an Alpine Ski Resort on Hydrology and Water Quality in the Northeastern U.S.: Preliminary Findings from a Field Study (United States)

    Wemple, B.; Shanley, J.; Denner, J.


    High elevation, forested watersheds are particularly vulnerable to stresses from development. Steep slopes and thin soils rapidly transmit water, nutrients and sediment when disturbed by logging, road construction or other activities associated with development. The effects of forest harvesting practices on streamflow and water quality in high-elevation, forested watersheds have been well studied and provide relevant information about the susceptibility of these ecosystems to anthropogenic disturbance. Few studies have directly addressed the hydrologic or water quality effects of ski resort development on mountain streams, and these studies draw almost entirely from western U.S. examples. Ski resorts in the eastern U.S. face particular development pressures. Transient and unpredictable snow conditions generate extensive need for snowmaking. Competitive economic pressure has motivated plans for slope-side village development and summer recreation facilities at many eastern U.S. ski resorts. Here, we report preliminary findings of a recently initiated paired-watershed study to examine the effects of alpine ski area development on water quantity and quality. Our study area is located on the eastern slope of Mt. Mansfield, Vermont, and includes the basins of Ranch Brook (9.6 sq km) and West Branch (11.7 sq km). Ranch Brook is undeveloped, except for a network of cross-country ski trails and unsurfaced access roads, and serves as our control watershed. West Branch encompasses nearly an entire major ski resort, with an extensive network of alpine ski lifts and trails, day lodges, snowmaking facilities, and vacation homes. A major expansion of resort facilities and ski trails has recently received state approval. Our preliminary analysis indicates distinct differences in runoff and water quality between the two basins. Differences in basin hydrographs suggest that ski trails alter the timing and magnitude of runoff, particularly during spring snowmelt. Elevated

  7. Preliminary Investigation of Workplace-Provided Compressed Mindfulness-Based Stress Reduction with Pediatric Medical Social Workers. (United States)

    Trowbridge, Kelly; Mische Lawson, Lisa; Andrews, Stephanie; Pecora, Jodi; Boyd, Sabra


    Mindfulness practices, including mindfulness meditation, show promise for decreasing stress among health care providers. This exploratory study investigates the feasibility of a two-day compressed mindfulness-based stress reduction (cMBSR) course provided in the hospital workplace with pediatric health care social workers. The standard course of Jon Kabat-Zinn's MBSR requires a participant commitment to eight weeks of instruction consisting of one 2.5-hour-per-week class, a single day retreat, and 45 minutes of practice for six of seven days each week. Commitments to family, work, caregiving, education, and so on, as well as limitations such as distance, may prevent health care providers from participating in a standard MBSR course. Using t tests, researchers measured the effect of cMBSR on (a) positive and negative experiences in pediatric social work, (b) perceived stress, (c) mindfulness, and (d) caring self-efficacy (as a component of patient- and family-centered care). Results included significant differences between the pre- and post-intervention outcome variables on the Professional Quality of Life Secondary Traumatic Stress subscale, the Mindful Attention and Awareness Scale, and the Caring Efficacy Scale. Findings found adequate evidence for the feasibility of cMBSR design and for a need of a more rigorous study of the effects of the cMBSR intervention. © 2017 National Association of Social Workers.

    Lisabeth D Finn


    Full Text Available BackgroundHigher cancer morbidity and mortality rates for the Indigenous population comparedto the overall Australian population has underlined the critical need to improve accessfor Aboriginal people to cancer treatment services. This paper describes anIndigenous Women’s Cancer Support Group (IWCSG established to supportIndigenous people with cancer and their carers/relatives and to facilitate Aboriginalaccess to cancer screening and treatment. Preliminary findings from an evaluation ofthe group are presented.MethodsThe study employed qualitative research methods to describe IWCSG operations andinvestigate the group’s effectiveness. It included one-on-one interviews with 11Geraldton-based health service providers, the IWCSG coordinator, and 10 womenwho have been linked to IWCSG support, as well as observation of group meetings.ResultsDescriptive outcomes relate to group operations, group effectiveness, group benefitsand future development of the group. A cultural strength of IWCSG is its ability tooperate confidentially behind the scenes, providing emotional support and practicalhelp directly to Indigenous people concerned about privacy and shame issues. Theimportant cultural role IWCSG plays in overcoming communication and othercultural barriers to accessing cancer treatment was unanimously recognised by healthservice providers. Aboriginal women supported by IWCSG spoke about an increasedsense of safety, trust and support in accessing and navigating mainstream cancerservices. A critical issue emerging from the research is the need for further development of effective collaborative working relationships between IWCSGmembers and health service providers.ConclusionsThe IWCSG has the potential to inform an effective model for facilitating Indigenousaccess both to cancer treatment and to mainstream treatment for a variety of healthproblems. Future research is required to explore the applicability of Indigenoussupport groups and to focus on the

  11. Towards a cooperation between the arts, space science research and the European Space Agency - Preliminary findings of the ESA Topical Team Arts and Sciences (ETTAS) (United States)

    Pell, Sarah Jane; Imhof, Anna Barbara; Waldvogel, Christian; Kotler, J. Michelle; Peljhan, Marko


    The arts offer alternative insights into reality, which are explored by science in general, and broadened by the activities conducted by the European Space Agency [4] and other space agencies. Similar to the way the members of ESA are ambassadors for spaceflight and science, artists and cultural professionals are ambassadors for human expression, experimentation, and exploration. In June 2011, the ESA Topical Team Arts and Sciences (ETTAS) held a three-day workshop at the European Astronaut Centre in Cologne, Germany. During this workshop, topics and ideas were discussed to develop initiatives between the arts, sciences and ESA. The aim was to foster and expand the human and cultural aspects of space exploration, and at the same time offer a means of communication that aims to reach audiences beyond the scope of traditional space-related channels. The consensus of the team was that establishing and sustaining a transdisciplinary professional community consisting of ESA representatives, scientists and artists would fuel knowledge transfer, and mutual inspiration. Potential ways to provide a sustainable cooperation within and between the various groups were discussed. We present the preliminary findings including a number of measures and mechanisms to initiate and conduct such an initiative. Plausible organisational measures, procedures and consequences, as well as a proposition on how to proceed are also discussed. Overall, the involvement and cooperation between the arts, space science research and ESA will enhance in the citizens of the ESA member states the sense of public ownership of ESA results, and participation in ESA's research.

    Faith-based organizations (FBOs) have been successful in delivering health promotion programs for African Americans, though few studies have been conducted among Latinos. Even fewer have focused on organizational change, which is required to sustain community-based initiatives. We hypothesized that FBOs serving Latinos would be more likely to offer evidence-based strategies (EBS) for cancer control after receiving a capacity enhancement intervention to implement health programs, and designed the CRUZA trial to test this hypothesis. This paper describes the CRUZA design and baseline findings. We identified Catholic parishes in Massachusetts that provided Spanish-language mass (n = 65). A baseline survey assessed organizational characteristics relevant to adoption of health programs, including readiness for adoption, "fit" between innovation and organizational mission, implementation climate, and organizational culture. In the next study phase, parishes that completed the baseline assessment will be recruited to a randomized cluster trial, with the parish as the unit of analysis. Both groups will receive a Program Manual and Toolkit. Capacity Enhancement parishes will also be offered technical support, assistance forming health committees and building inter-institutional partnerships, and skills-based training. Of the 49 parishes surveyed at baseline (75%), one-third (33%) reported having provided at least one health program in the prior year. However, only two program offerings were cancer-specific. Nearly one-fifth (18%) had an active health ministry. There was a high level of organizational readiness to adopt cancer control programs, high congruence between parish missions and CRUZA objectives, moderately conducive implementation climates, and organizational cultures supportive of CRUZA programming. Having an existing health ministry was significantly associated with having offered health programs within the past year. Relationships between health program

    Full Text Available Abstract Background Health care providers in many countries have delivered interventions to improve physical activity levels among their patients. Thus far, less is known about the population's interest to increase their physical activity levels and their opinion about the health care provider's role in physical activity promotion. The aims of this paper were to investigate the self-reported physical activity levels of the population and intention to increase physical activity levels, self-perceived need for support, and opinions about the responsibilities of both individuals and health care providers to promote physical activity. Methods A regional public health survey was mailed to 13 440 adults (aged 18-84 years living in Östergötland County (Sweden in 2006. The survey was part of the regular effort by the regional Health Authorities. Results About 25% of the population was categorised as physically active, 38% as moderately active, 27% as somewhat active, and 11% as low active. More than one-third (37% had no intentions to increase their physical activity levels, 36% had thought about change, while 27% were determined to change. Lower intention to change was mainly associated with increased age and lower education levels. 28% answered that physical activity was the most important health-related behaviour to change "right now" and 15% of those answered that they wanted or needed support to make this change. Of respondents who might be assumed to be in greatest need of increased activity (i.e. respondents reporting poor general health, BMI>30, and inactivity more than one-quarter wanted support to make improvements to their health. About half of the respondents who wanted support to increase their physical activity levels listed health care providers as a primary source for support. Conclusions These findings suggest that there is considerable need for physical activity interventions in this population. Adults feel great responsibility for

  14. Providers' beliefs about the effectiveness of the HPV vaccine in preventing cancer and their recommended age groups for vaccination: Findings from a provider survey, 2012. (United States)

    Berkowitz, Z; Malone, M; Rodriguez, J; Saraiya, M


    The human papillomavirus (HPV) vaccine was recommended in 2007 by the Advisory Committee on Immunization Practices (ACIP) to preadolescent and adolescent girls. Vaccination initiation was recommended at age 11-12 years with the option to start at age 9. Catchup vaccination was recommended to females aged 13-26 previously not vaccinated. However, vaccination coverage remains low. Studies show that the HPV vaccine can prevent cervical, vulvar, vaginal, anal and some oropharyngeal cancers and that provider recommendation of vaccines can improve low vaccination rates. Using data from 2012 DocStyles, an annual, web-based survey of U.S. healthcare professionals including physicians and nurse practitioners (n=1753), we examined providers' knowledge about the effectiveness of the HPV vaccine in preventing cancer and their vaccine recommendation to all age-eligible females (9-26 years). Descriptive statistics and Chi-square tests were used to assess differences across specialties. Knowledge about HPV vaccine effectiveness in preventing cervical cancer was highly prevalent (96.9%), but less so for anal, vaginal, vulvar and oropharyngeal cancers. Only 14.5% of providers recommended the vaccine to all age-eligible females and 20.2% recommended it to females aged 11-26 years. Knowledge assessment of cancers associated with HPV and vaccination recommendations varied significantly among providers (pvaccine to girls older than 11-12 years. Improving providers' knowledge about HPV-associated cancers and the age for vaccination initiation, communicating messages focusing on the vaccine safety and benefits in cancer prevention and on the importance of its delivery prior to sexual onset, may improve HPV vaccine coverage.

    Metaxia Pavlakou


    Full Text Available The purpose of this study is to examine the possible benefits of participation in group singing for people with eating disorders in a non-clinical context. The creation of a group singing workshop for women that exhibited disordered eating provided the opportunity to explore the participants’ experiences as perceived by them. A qualitative approach utilizing a semi-structured interview was employed to explore in depth the women’s perceptions regarding the group singing workshop. A thematic analysis of the data identified four main categories concerning the benefits of group singing for the population under study. The theoretical model of Sears (1968 of the processes in music therapy and its application on anorexic clients (Parente 1989 informed the discussion of the empirical findings.

  16. Natalizumab Significantly Improves Cognitive Impairment over Three Years in MS: Pattern of Disability Progression and Preliminary MRI Findings.

    Directory of Open Access Journals (Sweden)

    Flavia Mattioli

    Full Text Available Previous studies reported that Multiple Sclerosis (MS patients treated with natalizumab for one or two years exhibit a significant reduction in relapse rate and in cognitive impairment, but the long term effects on cognitive performance are unknown. This study aimed to evaluate the effects of natalizumab on cognitive impairment in a cohort of 24 consecutive patients with relapsing remitting MS treated for 3 years. The neuropsychological tests, as well as relapse number and EDSS, were assessed at baseline and yearly for three years. The impact on cortical atrophy was also considered in a subgroup of them, and are thus to be considered as preliminary. Results showed a significant reduction in the number of impaired neuropsychological tests after three years, a significant decrease in annualized relapse rate at each time points compared to baseline and a stable EDSS. In the neuropsychological assessment, a significant improvement in memory, attention and executive function test scores was detected. Preliminary MRI data show that, while GM volume did not change at 3 years, a significantly greater parahippocampal and prefrontal gray matter density was noticed, the former correlating with neuropsychological improvement in a memory test. This study showed that therapy with Natalizumab is helpful in improving cognitive performance, and is likely to have a protective role on grey matter, over a three years follow-up.

    Recent studies have proposed additional multidetector-row CT (MDCT) for prosthetic heart valve (PHV) dysfunction. References to discriminate physiological from pathological conditions early after implantation are lacking. We present baseline MDCT findings of PHVs 6 weeks post implantation. Patients were prospectively enrolled and TTE was performed according to clinical guidelines. 256-MDCT images were systematically assessed for leaflet excursions, image quality, valve-related artefacts, and pathological and additional findings. Forty-six patients were included comprising 33 mechanical and 16 biological PHVs. Overall, MDCT image quality was good and relevant regions remained reliably assessable despite mild-moderate PHV-artefacts. MDCT detected three unexpected valve-related pathology cases: (1) prominent subprosthetic tissue, (2) pseudoaneurysm and (3) extensive pseudoaneurysms and valve dehiscence. The latter patient required valve surgery to be redone. TTE only showed trace periprosthetic regurgitation, and no abnormalities in the other cases. Additional findings were: tilted aortic PHV position (n = 3), pericardial haematoma (n = 3) and pericardial effusion (n = 3). Periaortic induration was present in 33/40 (83 %) aortic valve patients. MDCT allowed evaluation of relevant PHV regions in all valves, revealed baseline postsurgical findings and, despite normal TTE findings, detected three cases of unexpected, clinically relevant pathology.

  18. The Relationship of Clinical, Cognitive and Social Measures in Schizophrenia: A Preliminary Finding Combining Measures in Probands and Relatives

    Directory of Open Access Journals (Sweden)

    David Huepe


    Full Text Available This study examines performance of schizophrenia patients, unaffected relatives and controls in social cognition, cognitive and psychiatric scales looking for possible markers of vulnerability in schizophrenia. Performance of schizophrenia patients from multiplex families, first-degree relatives, and matched controls was compared and, subsequently, discriminant analysis method was used for identifying the best predictors for group membership. By using Multigroup Discriminant Analyses on the three groups, the best predictors were PANSS, Premorbid Adjustment Scale, Faux Pas test, and a face/emotion categorizing task. This model obtained 82% correct global classification, suggesting that the combination of psychiatric scales and neuropsychological/social cognition tesks are the best approach for characterizing this disease. Although preliminary, our results suggest that social cognition tasks are robust markers of schizophrenia family impairments, and that combining clinical, social and neuropsychological measures is the best approach to asses patients and relatives vulnerability.

  19. Older Adult Stroke Survivors Discussing Post-stroke Depressive Symptoms with a Healthcare Provider: A Preliminary Analysis (United States)

    Klinedinst, N. Jennifer; Clark, Patricia C.; Dunbar, Sandra B.


    Purpose The purposes of this study were to examine the relationship between the post-stroke depressive symptoms, older adult stroke survivors’ perceptions of the depressive symptoms, and the congruence with an informal caregiver about the presence of depressive symptoms, and comfort talking to the healthcare provider with whether or not older stroke survivors discussed their depressive symptoms with a healthcare provider. Method A cross-sectional study where 44 caregiver/older adult stroke survivor dyads completed questionnaires including the Center for Epidemiologic Studies Depression Scale, Symptom Perception Questionnaire, and reporting of depressive symptoms to the healthcare provider via one time interview. Results Thirty-seven percent (n=16) of all older stroke survivors reported depressive symptoms to their healthcare provider. Of the stroke survivors who had high levels of depressive symptoms (CESD≥16; n=11), seven reported the depressive symptoms to their healthcare provider. Identifying the symptoms as possible depression and attributing the cause of the depressive symptoms to the stroke were related to stroke survivors reporting the depressive symptoms to a health care provider. Conclusions High functioning, older stroke survivors may benefit from strategies to help them identify when they experience depressive symptoms, in order to be able to play an active role in their recovery by appropriately discussing their symptoms with a healthcare provider.

  20. Work-related treatment for major depressive disorder and incapacity to work: preliminary findings of a controlled, matched study. (United States)

    Kröger, Christoph; Bode, Katharina; Wunsch, Eva-Maria; Kliem, Sören; Grocholewski, Anja; Finger, Friederike


    The aim of this study was to compare the effectiveness of work-related cognitive-behavioral treatment (W-CBT) with that of cognitive-behavioral treatment as usual (CBT-AU) for employees on sick leave as a result of a major depressive disorder (MDD). We collected data for 26 matched outpatients at pre- and posttreatment, as well as at 1-year follow-up. Outcome measures were the days of incapacity to work (DIW) as well as self-report measures (Beck Depression Inventory [BDI], Symptom Checklist 90-R [GSI], Life Satisfaction Questionnaire [FLZ]). We analyzed data with hierarchical linear modeling in a 2-level model. Therapy effects were defined in 3 ways: effect size (ES), response (based on the reliable change index), and remission compared with the general population's symptom level. The DIW were reduced significantly after both types of treatment, but employees showed even fewer DIW after W-CBT. At follow-up, significantly more employees were working as a result of W-CBT than with CBT-AU. Significant improvements on scores of self-rating measures corresponded with moderate-to-large effect sizes for both treatment types. Approximately 2 thirds of the treated employees were categorized as unimpaired on BDI scores at posttreatment and at follow-up. At least 1 half of the employees were classified as unimpaired on GSI scores at both assessment points. In future research, a randomized controlled trial should be conducted using a larger sample size to investigate the impact of moderators (e.g., employees at different branches of the company). Findings provided support for using common CBT techniques to enhance return to work without losing expected improvements at the symptom level. (c) 2015 APA, all rights reserved).

  1. Research based empathic knowledge for nursing: a translational strategy for disseminating phenomenological research findings to provide evidence for caring practice. (United States)

    Galvin, Kathleen T; Todres, Les


    We are interested in the kind of knowledge that is particularly relevant to caring practice and the way in which qualitative research findings can serve such knowledge. As phenomenological researchers we have been engaged with the question of how findings from such research can be re-presented and expressed more aesthetically. Such a movement towards a more aesthetic phenomenology may serve the communicative concern to express phenomena relevant to caring practice in ways that appeal to the 'head, hand and heart'. The paper first offers some thoughts about the complex kind of knowledge relevant to caring that is not only technical or propositional, but actionable and aesthetically moving as well. We call this kind of knowledge 'embodied relational understanding'. Further, the paper outlines the development of one way of serving a more aesthetic phenomenology whereby research findings can be faithfully and evocatively translated into more empathically impactful expressions. We call this process 'embodied interpretation'. It is guided by an epistemological framework grounded in the philosophies of Gadamer and Gendlin. We finally illustrate the process with reference to the experience of living after Stroke, and consider the value of this translational process for nursing education and practice.

  2. Barriers to Rural Induced Abortion Services in Canada: Findings of the British Columbia Abortion Providers Survey (BCAPS) (United States)

    Norman, Wendy V.; Soon, Judith A.; Maughn, Nanamma; Dressler, Jennifer


    Background Rural induced abortion service has declined in Canada. Factors influencing abortion provision by rural physicians are unknown. This study assessed distribution, practice, and experiences among rural compared to urban abortion providers in the Canadian province of British Columbia (BC). Methods We used mixed methods to assess physicians on the BC registry of abortion providers. In 2011 we distributed a previously-published questionnaire and conducted semi-structured interviews. Results Surveys were returned by 39/46 (85%) of BC abortion providers. Half were family physicians, within both rural and urban cohorts. One-quarter (17/67) of rural hospitals offer abortion service. Medical abortions comprised 14.7% of total reported abortions. The three largest urban areas reported 90% of all abortions, although only 57% of reproductive age women reside in the associated health authority regions. Each rural physician provided on average 76 (SD 52) abortions annually, including 35 (SD 30) medical abortions. Rural physicians provided surgical abortions in operating rooms, often using general anaesthesia, while urban physicians provided the same services primarily in ambulatory settings using local anaesthesia. Rural providers reported health system barriers, particularly relating to operating room logistics. Urban providers reported occasional anonymous harassment and violence. Conclusions Medical abortions represented 15% of all BC abortions, a larger proportion than previously reported (under 4%) for Canada. Rural physicians describe addressable barriers to service provision that may explain the declining accessibility of rural abortion services. Moving rural surgical abortions out of operating rooms and into local ambulatory care settings has the potential to improve care and costs, while reducing logistical challenges facing rural physicians.

  3. A stereological study of glomerular number and volume: preliminary findings in a multiracial study of kidneys at autopsy. (United States)

    Hoy, Wendy E; Douglas-Denton, Rebecca N; Hughson, Michael D; Cass, Alan; Johnson, Kelli; Bertram, John F


    This report describes preliminary results of a study of glomerular number and volume and their associations, in kidneys of people coming to autopsy. Both kidneys were weighed at autopsy and the right kidney was perfusion-fixed and sub-sampled for stereological estimation of total glomerular number, and of mean renal corpuscle volume, using the physical disector/fractionator combination. The 78 kidneys studied so far were from Australian Aborigines, Australian non-Aborigines, US blacks and US whites, ages newborn to 84 years. Glomerular number ranged almost ninefold (from 210,332 to 1,825,380), with mean (SD) of 784,909 (314,686); it decreased throughout adult life (r=-0.32, P=0.009). Mean renal corpuscle volume varied 5.6-fold in adults and was inversely correlated with glomerular number (r=-0.38, P=0.001). Total renal corpuscle volume varied in adults by a factor of 15.8. Kidney weight correlated with body surface area (BSA) at all ages (r=0.76, P obsolescence. Much, however, remains to be done, including evaluation of history, clinical features, accompanying pathology, detailed renal morphology, and further pursuit of potentially defining characteristics in high risk groups.

    Naeem, Farooq; Waheed, Waquas; Gobbi, Mary; Ayub, Muhammad; Kingdon, David


    There is sufficient research evidence in favour of cognitive therapy in western world. However, only limited research has been carried out on its effectiveness in other countries. It is suggested that adaptations in content, format and delivery are needed before CBT can be employed in non-western cultures. We describe a preliminary evaluation of culturally adapted CBT for depression in Pakistan. We aimed to evaluate the efficacy of this culturally adapted CBT using a therapist manual. In a randomized controlled trial we compared combination of CBT and antidepressants with antidepressants alone (treatment as usual) in primary care. Referred patients with ICD-10 diagnosis of depression were invited to participate and randomized to the intervention and control groups. Hospital Anxiety and Depression Scale (HADS) and Bradford Somatic Inventory (BSI) were used to measure changes in depression, anxiety and somatic symptoms. Seventeen patients each were randomized to each arms of the trial. Except for financial status there were no differences between the two groups on various demographic variables. Patients receiving CBT showed statistically significant improvement on measures of depression (p therapy. A culturally sensitive manualized CBT was effective in reducing symptoms of depression and anxiety in Pakistan.

  5. Three-dimensional sonohysterography for examination of the uterine cavity in women with abnormal uterine bleeding: Preliminary findings (United States)

    Sconfienza, L.M.; Lacelli, F.; Caldiera, V.; Perrone, N.; Piscopo, F.; Gandolfo, N.; Serafini, G.


    Introduction To compare the diagnostic values of three-dimensional sonohysterography (3DSH), transvaginal ultrasound (TVUS), and 2-dimensional sonohysterography (2DSH) in the work-up of abnormal uterine bleeding (AUB), in particular the ability of each method to identify intracavitary lesions arising from the endometrium or uterine wall. Materials and methods 24 patients referred for AUB underwent TVUS followed by 2-D and 3-D HS in the same session. Three-dimensional data were acquired with a free-hand technique during maximal distention of the uterus. Within 10 days of the sonographic session, each patient underwent hysteroscopy, which was considered the reference standard. For each of the 3 imaging methods, we calculated sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. Results Hysteroscopy demonstrated the presence of an intrauterine lesion in 21/24 patients (87.5%). In 3/24 patients hysteroscopy was negative. For TVUS, 2DSH, and 3DSH, sensitivity was 76% (16/21), 90% (19/21), 100% (21/21), respectively; specificity was 100% (3/3), 100% (19/19), 100% (21/21); PPV was 100%, 100%, 100%; NPV was 37%, 60%, 100%; accuracy was 76%, 90%, 100%. Conclusions 3DSH is more sensitive that 2DSH or TVUS in the detection of intrauterine lesions. If these preliminary results are confirmed in larger studies, 3DSH could be proposed as a valuable alternative to diagnostic hysteroscopy. PMID:23396822

    Full Text Available Preliminary assessment of a new prototype ultrasound-based hypersonic vitrector (HV by qualitatively examining the histopathological changes in the retina and vitreous body after pars plana vitrectomy (PPV and its ability to fragment vitreous collagen.Fourteen porcine cadaveric eyes, 20 eyes in live swine and six human cadaveric eyes underwent PPV using the HV or a pneumatic guillotine vitrector (GV. An additional 4 porcine crystalline lenses were touched with either the HV or GV for 1 minute. Following PPV, human vitreous was removed and processed for electron microscopy (EM. Eyes and lenses were fixed and sectioned for light microscopy (LM.There were no macroscopic retinal or optic nerve defects associated with either HV or GV PPVs. Cadaveric retinal specimens showed separation of the inner limiting membrane (ILM and vacuolization and fragmentation at the nerve fiber layer (NFL and the ganglion cell layer (GCL. ILM fragmentation and separation were found after PPV in live swine with both vitrectors. Small disruptions of the posterior capsule or structural lens defects were found after HV touch. The EM analysis revealed more fragmentation of human vitreous collagen fibrils after HV compared to GV PPV.LM and EM analysis of retina, vitreous, and crystalline lens after PPV showed similar morphological changes using the HV or the GV. Vitreous fragmentation appeared more effective with the HV. Overall this study suggests that the HV may be a promising new technology. More work is needed to quantitatively assess its safety and efficacy.

  7. Preliminary findings on the antimony levels of Quiroga river water in the vicinity of a long-abandoned stibnite mine. (United States)

    González-Alvarez, M E; Aboal-Somoza, M; Bermejo-Barrera, P


    A UV-Vis spectrophotometric method was developed as a preliminary approach to the determination of antimony in water samples from a river that flows very close to an abandoned mining site. The analyte is complexed with ammonium pyrrolidinedithiocarbamate and absorbance of the complex is measured at 291.06 nm. The standard additions method is mandatory in view of the matrix effect observed, and the response is linear at least up to 9.3 microg/mL of antimony. The sensitivity of the method is 2.609 x 10(-2) mL/microg, whereas the limits of detection and quantification are, respectively, 0.2 and 0.6 microg/mL. The repeatability, expressed as mean relative standard deviation of the measurements within the calibration range, is 2.0%, whereas the repeatability of the entire procedure is 0.3%. The mean analytical recovery within the calibration range was 102.6%. The method was successfully applied to river water samples.

  8. Key findings: a qualitative assessment of provider and patient perceptions of HIV/AIDS in South Africa. (United States)

    Ransom, James; Johnson, Anton F


    In 1997, at the Davos International Economic Forum, Nelson Mandela stated that "the poor, the vulnerable, the unschooled, the socially marginalized, the women, and the children, those who bear the burden of colonial legacy-these are the sectors of society which bear the burden of AIDS" (Richter, 2001). Nearly a decade later, that statement still holds true, especially in Mr. Mandela's home country. South Africa continues to have one of the world's highest prevalence ratios of HIV infection (UNAIDS, 2002). This paper explores the significance of perceptions, knowledge, practices, and attitudes toward HIV/AIDS in two important groups in South Africa: health care providers based in public health clinics and their patients. This paper will assess the provider-patient interaction from the perspective of members of the South African HIV/AIDS treatment and prevention community. The analysis will examine the results of in-depth interviews and focus group discussions with providers and patients, respectively, in two of South Africa's nine provinces. Between December 2002 and April 2003 in Guateng and KwaZulu-Natal provinces, we conducted (1) in-depth interviews of a spectrum of health care providers at five local public health clinics and (2) focus groups of patients who patronize those clinics. The results show that there are gaps in the HIV/AIDS knowledge of some of the health care providers and that the participants' health beliefs and practices are embedded in the social conditions in which they live and work, which has a ripple effect on their risk behaviors and trumps any intervention messages from their health care providers and larger public health intervention messages.

  10. A preliminary report of musculoskeletal dysfunction in female chronic pelvic pain: a blinded study of examination findings. (United States)

    Neville, Cynthia E; Fitzgerald, Colleen M; Mallinson, Trudy; Badillo, Suzanne; Hynes, Christina; Tu, Frank


    Female chronic pelvic pain is prevalent and causes disability. Can women with self-reported chronic pelvic pain (CPP) be distinguished from pain-free women by demonstrating a greater number of abnormal musculoskeletal findings on examination? In this cross-sectional study, blinded examiners performed 9 physical exam maneuvers on 48 participants; 19 with CPP, and 29 pain-free. Frequency of positive findings between groups, total number of positive exam findings, cluster analysis, and sensitivity - specificity analyses were performed. Women with CPP presented with significantly more abnormal findings than pain-free women. By using two examination maneuvers, examiners correctly classified women with self-reported CPP from pain-free women 85% of the time. Abnormal findings on musculoskeletal exam are more common in women with self-reported CPP. Women with CPP might benefit from a faster time to diagnosis and improved treatment outcomes if a musculoskeletal contribution to CPP was identified earlier. Copyright © 2011 Elsevier Ltd.

  11. A Brief Report: Lessons Learned and Preliminary Findings of Progreso en Salud, an HIV Risk Reduction Intervention for Latina Seasonal Farmworkers. (United States)

    Kanamori, Mariano; De La Rosa, Mario; Diez, Stephanie; Weissman, Jessica; Trepka, Mary Jo; Sneij, Alicia; Schmidt, Peter; Rojas, Patria


    Throughout the past decade, HIV rates in Florida-particularly South Florida, where many Latina seasonal farmworkers reside and work-have ranked among the highest in the nation. In this brief report, we delineate important lessons learned and preliminary findings from the implementation of the HIV prevention intervention Progreso en Salud (Progress in Health). Among the 114 Latina seasonal farmworker participants, there were significant increases from baseline to 6-month follow-up in the percentages of overall condom use, HIV testing, HIV/AIDS-related communications with friends, HIV knowledge, condom use self-efficacy, and correct use of condoms. Lessons learned from this study can be used to inform future HIV intervention strategies to improve the adoption and maintenance of HIV risk reduction behaviors among high-risk Latina seasonal workers and other high-risk underserved populations. Future research is needed to support our findings.

  14. Findings from the NIMH Multimodal Treatment Study of ADHD (MTA): implications and applications for primary care providers. (United States)

    Jensen, P S; Hinshaw, S P; Swanson, J M; Greenhill, L L; Conners, C K; Arnold, L E; Abikoff, H B; Elliott, G; Hechtman, L; Hoza, B; March, J S; Newcorn, J H; Severe, J B; Vitiello, B; Wells, K; Wigal, T


    In 1992, the National Institute of Mental Health and 6 teams of investigators began a multisite clinical trial, the Multimodal Treatment of Attention-Deficit Hyperactivity Disorder (MTA) study. Five hundred seventy-nine children were randomly assigned to either routine community care (CC) or one of three study-delivered treatments, all lasting 14 months. The three MTA treatments-monthly medication management (usually methylphenidate) following weekly titration (MedMgt), intensive behavioral treatment (Beh), and the combination (Comb)-were designed to reflect known best practices within each treatment approach. Children were assessed at four time points in multiple outcome. Results indicated that Comb and MedMgt interventions were substantially superior to Beh and CC interventions for attention-deficit hyperactivity disorder symptoms. For other functioning domains (social skills, academics, parent-child relations, oppositional behavior, anxiety/depression), results suggested slight advantages of Comb over single treatments (MedMgt, Beh) and community care. High quality medication treatment characterized by careful yet adequate dosing, three times daily methylphenidate administration, monthly follow-up visits, and communication with schools conveyed substantial benefits to those children that received it. In contrast to the overall study findings that showed the largest benefits for high quality medication management (regardless of whether given in the MedMgt or Comb group), secondary analyses revealed that Comb had a significant incremental effect over MedMgt (with a small effect size for this comparison) when categorical indicators of excellent response and when composite outcome measures were used. In addition, children with parent-defined comorbid anxiety disorders, particularly those with overlapping disruptive disorder comorbidities, showed preferential benefits to the Beh and Comb interventions. Parental attitudes and disciplinary practices appeared to mediate

    Provider-initiated HIV testing and counselling (PITC) is promoted as a means to increase HIV case finding. We assessed the effectiveness of PITC to increase HIV testing rate and HIV case finding among outpatients in Rwandan health facilities (HF). PITC was introduced in six HFs in 2009-2010. HIV

  19. An Acoustical Study of the Fricative /s/ in the Speech of Palestinian-speaking Broca's Aphasics – Preliminary Findings

    Directory of Open Access Journals (Sweden)

    Hisham Adam


    Full Text Available This study was conducted with four Palestinian-speaking Broca's aphasics and four normal speakers to examine the production of the fricative /s/ and to analyze the difference in acoustic patterns between the two groups. The acoustic analysis revealed that the Broca's aphasics were able to maintain the phonetic distinction between voiced and voiceless fricatives and did not exhibit voicing or devoicing errors. This result is inconsistent with findings from other languages. The spectral peak of the alveolar /s/ was lower for the aphasic subjects than for the control speakers. The Broca's aphasics displayed a longer duration for /s/ than the control subjects did. The /s/ spectra for the Broca's aphasics were "flatter" than the /s/ spectra for the control speakers and were characterized by a relatively low-frequency energy peak. Substitution errors predominated. In most cases, a one-distinctive-feature error occurred that primarily involved the place of articulation. Generally, the findings of the study suggest that the errors exhibited by Broca's aphasics reflect articulatory movements and articulatory implementation deficits rather than a selection of inappropriate speech segments.

  20. Agents of change: undergraduate students' attitudes following observations of speech-language pathology service delivery: preliminary findings. (United States)

    Miller, Suzanne M; Ciocci, Sandra R


    Undergraduate communication sciences and disorders students' attitudes toward speech-language pathology (SLP) clinical services to children and adults prior to and following community-based observations were examined. Participants (n=25) completed an online survey to elicit their opinions regarding their perceptions of their observation experiences. Findings revealed that after completion of community-based SLP clinical observations, 16 (64%) respondents reported a continued interest in a child-based clinical focus; 12 (48%) respondents continued to consider a clinical interest in adults, while 5 respondents (20%) changed career interests to an adult focus based on their observation experiences. Findings support the notion that observations of SLP appear to significantly influence students' career choices. Clinical observations typically occur at the junior/senior undergraduate levels; therefore, suggestions are offered for inclusion of gerontology education embedded throughout the undergraduate communication sciences and disorders curricula to foster and expand students' knowledge of aging, and to prepare our students to meet the healthcare challenges of elders in the 21st century.

  1. Human adaptation to isolated and confined environments: Preliminary findings of a seven month Antarctic winter-over human factors study (United States)

    Evans, Gary W.; Stokols, Daniel; Carrere, Sybil


    This field study was conducted during the last decade of an austral winter-over at Palmer Station in the Antarctic. The purpose of the study was to understand temporal patterns in physiological arousal and psychological mood over the course of the mission. The investigators were principally interested in how people adapted over time to chronic and acute stressors, and how people use and modify their built environment. Physiological and psychological data were collected several times a week, and information on behavior and the use of physical facilities was collected monthly. Physiological and psychological data were compared with social changes in the setting toward the development of a sequential model of human-environment transactional relationships. Based on the study results, guidelines for design of future isolated and confined environments (ICEs) included: plan space for items which make people feel at home, provide materials to allow people to personalize their environment, allow for flexible environments, provide areas for visual and auditory privacy, equip areas for socializing and remove them from private areas, and provide facilities for exercise and for projects involving physical activity. The study offers guidelines about patterns of adaption that could be expected in an ICE, discusses how these settings can be programmed to facilitate successful adjustment, and provides information about how to design future ICE habitats to maximize a healthy living environment.

    Person-Environment (P-E) fit models provide a conceptually powerful way to think about career development, vocational choice, and occupational success. The work reported here focuses on yet another pair of P-E criteria: self-reported individual capacity for information processing (the ability to tolerate information overload from a variety of…

  3. Brief Report: Physical Activity, Body Mass Index and Arterial Stiffness in Children with Autism Spectrum Disorder: Preliminary Findings. (United States)

    Heffernan, Kevin S; Columna, Luis; Russo, Natalie; Myers, Beth A; Ashby, Christine E; Norris, Michael L; Barreira, Tiago V


    We examined the association between physical activity (PA), body mass index (BMI) and novel measures of subclinical cardiovascular disease (CVD) in 15 children with autism spectrum disorder (ASD) (mean age 7 ± 2 years, 2 girls). PA was objectively assessed using accelerometry as time spent in moderate-vigorous physical activity (MVPA). Arterial stiffness was measured via aortic pulse wave velocity (PWV) and taken as a marker of subclinical CVD risk. MVPA was inversely associated with aortic PWV (r = - 0.46, p < 0.05). BMI percentile was positively associated with aortic PWV (r = 0.61, p < 0.05). Overall findings suggest that reduced PA and higher body mass in children with ASD are associated with increased arterial stiffness which may have a detrimental impact on overall cardiovascular health.

  4. From early stress to 12-month development in very preterm infants: Preliminary findings on epigenetic mechanisms and brain growth. (United States)

    Fumagalli, Monica; Provenzi, Livio; De Carli, Pietro; Dessimone, Francesca; Sirgiovanni, Ida; Giorda, Roberto; Cinnante, Claudia; Squarcina, Letizia; Pozzoli, Uberto; Triulzi, Fabio; Brambilla, Paolo; Borgatti, Renato; Mosca, Fabio; Montirosso, Rosario


    Very preterm (VPT) infants admitted to Neonatal Intensive Care Unit (NICU) are at risk for altered brain growth and less-than-optimal socio-emotional development. Recent research suggests that early NICU-related stress contributes to socio-emotional impairments in VPT infants at 3 months through epigenetic regulation (i.e., DNA methylation) of the serotonin transporter gene (SLC6A4). In the present longitudinal study we assessed: (a) the effects of NICU-related stress and SLC6A4 methylation variations from birth to discharge on brain development at term equivalent age (TEA); (b) the association between brain volume at TEA and socio-emotional development (i.e., Personal-Social scale of Griffith Mental Development Scales, GMDS) at 12 months corrected age (CA). Twenty-four infants had complete data at 12-month-age. SLC6A4 methylation was measured at a specific CpG previously associated with NICU-related stress and socio-emotional stress. Findings confirmed that higher NICU-related stress associated with greater increase of SLC6A4 methylation at NICU discharge. Moreover, higher SLC6A4 discharge methylation was associated with reduced anterior temporal lobe (ATL) volume at TEA, which in turn was significantly associated with less-than-optimal GMDS Personal-Social scale score at 12 months CA. The reduced ATL volume at TEA mediated the pathway linking stress-related increase in SLC6A4 methylation at NICU discharge and socio-emotional development at 12 months CA. These findings suggest that early adversity-related epigenetic changes might contribute to the long-lasting programming of socio-emotional development in VPT infants through epigenetic regulation and structural modifications of the developing brain.

  5. Health information ties: preliminary findings on the health information seeking behaviour of an African-American community

    Directory of Open Access Journals (Sweden)

    Ophelia T. Morey


    Full Text Available Introduction. The purpose of this study is to explore the health information seeking behaviour of African-Americans using Granovetter's strength of weak ties as the theoretical framework. Method. A listed household (LHH telephone survey of 216 residents who reside on the Near East Side of Buffalo, New York. Using the Rand( feature in MS Excel a random sample was drawn from the LHH telephone numbers that were randomly selected from census tracts covering the target area in Buffalo, New York. Random samples were drawn three times until at least 200 telephone surveys were completed. Analysis. Data analysis was completed using SPSS 13.0 for Windows. Both bivariate and multivariate analyses were performed along with analyzing descriptive statistics and chi-square to determine the association between the source of health information as related to demographics and tie strength between individuals. Results. Overall, most respondents rely on a health service professional for health information (45.5% followed by a web site (14.1%. Respondents reported having a 'somewhat close' (significant tie relationship with health care professionals as compared to having a 'very close' (core tie relationship with family members. The importance of health service professionals as a significant or weak tie in health information seeking is consistent with the strength of weak ties theory. Results on proxy searching behaviour or searching on behalf of another person are also examined. Most respondents sought information for themselves (76.2%, although 22.2 percent sought health information on behalf of another person. Conclusion. : These findings confirm the important role of health service professionals (weak tie in health information seeking by underserved populations and suggest the need for investigation on the information giving behaviour of these professionals. These findings also demonstrate the need for further research on strong ties or close family and friends

    Highlights: • Purely intra-epiphyseal stress injuries of the proximal tibial epiphysis are described for the first time. • The variation in the MRI findings of these injuries depending on the stage of maturation is demonstrated. • We postulate a patho-mechanism to explain the variations in site and appearance of stress injuries in this region. - Abstract: Stress induced injuries affecting the physeal plate or cortical bone in children and adolescents, especially young athletes, have been well described. However, there are no reports in the current English language literature of stress injury affecting the incompletely ossified epiphyseal cartilage. We present four cases of stress related change to the proximal tibial epiphysis (PTE) along with their respective magnetic resonance imaging (MRI) appearances ranging from subtle oedema signal to a pseudo-tumour like appearance within the epiphyseal cartilage. The site and pattern of intra-epiphyseal injury is determined by the type of tissue that is affected, the maturity of the skeleton and the type of forces that are transmitted through the tissue. We demonstrate how an awareness of the morphological spectrum of MRI appearances in intra-epiphyseal stress injury and the ability to identify concomitant signs of stress in other nearby structures can help reduce misdiagnosis, avoid invasive diagnostic procedures like bone biopsy and reassure patients and their families.

  7. Childhood Conscientiousness and Leukocyte Telomere Length 40 Years Later in Adult Women--Preliminary Findings of a Prospective Association.

    Directory of Open Access Journals (Sweden)

    Grant W Edmonds

    Full Text Available Leukocyte telomere length (LTL shortens with age, and is a prospective marker of mortality related to cardiovascular disease. Many health behaviors and social environmental factors have been found to be associated with LTL. Several of these are also associated with conscientiousness, a dispositional personality trait. Conscientiousness is a propensity to be planful, adhere to social norms, and inhibit pre-potent responses. Like LTL, conscientiousness is prospectively related to mortality, possibly through cumulative effects on health over the life course via multiple pathways. As a result, we hypothesized that childhood levels of conscientiousness would predict LTL prospectively in adulthood. We selected a sample of 60 women in the Hawaii Personality and Health Cohort; 30 described by their teachers as high on conscientiousness in childhood and 30 described as low on the trait. Dried blood spot samples collected in adulthood 40 years later were used as sources of DNA for the LTL assay. Conscientiousness was associated with longer LTL (p = .02. Controlling for age did not account for this association. Controlling for education and physiological dysregulation partially attenuated the association, and the effect remained significant when accounting for differences in LTL across cultural groups. These results represent the first evidence that childhood personality prospectively predicts LTL 40 years later in adulthood. Our findings would be consistent with a mediation hypothesis whereby conscientiousness predicts life paths and trajectories of health that are reflected in rates of LTL erosion across the lifespan.

  8. Meeting report: discussions and preliminary findings on extracellular RNA measurement methods from laboratories in the NIH Extracellular RNA Communication Consortium

    Directory of Open Access Journals (Sweden)

    Louise C. Laurent


    Full Text Available Extracellular RNAs (exRNAs have been identified in all tested biofluids and have been associated with a variety of extracellular vesicles, ribonucleoprotein complexes and lipoprotein complexes. Much of the interest in exRNAs lies in the fact that they may serve as signalling molecules between cells, their potential to serve as biomarkers for prediction and diagnosis of disease and the possibility that exRNAs or the extracellular particles that carry them might be used for therapeutic purposes. Among the most significant bottlenecks to progress in this field is the lack of robust and standardized methods for collection and processing of biofluids, separation of different types of exRNA-containing particles and isolation and analysis of exRNAs. The Sample and Assay Standards Working Group of the Extracellular RNA Communication Consortium is a group of laboratories funded by the U.S. National Institutes of Health to develop such methods. In our first joint endeavour, we held a series of conference calls and in-person meetings to survey the methods used among our members, placed them in the context of the current literature and used our findings to identify areas in which the identification of robust methodologies would promote rapid advancements in the exRNA field.

  9. Random number generation in bilingual Balinese and German students: preliminary findings from an exploratory cross-cultural study. (United States)

    Strenge, Hans; Lesmana, Cokorda Bagus Jaya; Suryani, Luh Ketut


    Verbal random number generation is a procedurally simple task to assess executive function and appears ideally suited for the use under diverse settings in cross-cultural research. The objective of this study was to examine ethnic group differences between young adults in Bali (Indonesia) and Kiel (Germany): 50 bilingual healthy students, 30 Balinese and 20 Germans, attempted to generate a random sequence of the digits 1 to 9. In Balinese participants, randomization was done in Balinese (native language L1) and Indonesian (first foreign language L2), in German subjects in the German (L1) and English (L2) languages. 10 of 30 Balinese (33%), but no Germans, were unable to inhibit habitual counting in more than half of the responses. The Balinese produced significantly more nonrandom responses than the Germans with higher rates of counting and significantly less occurrence of the digits 2 and 3 in L1 compared with L2. Repetition and cycling behavior did not differ between the four languages. The findings highlight the importance of taking into account culture-bound psychosocial factors for Balinese individuals when administering and interpreting a random number generation test.

  11. Usefulness of multiparametric computerized tomography findings in the differential diagnosis of stroke mimics of epileptic origin: A preliminary study. (United States)

    López Ruiz, R; Quintas, S; Largo, P; de Toledo, M; Carreras, M T; Gago-Veiga, A; Manzanares, R; Vivancos, J


    Thirty percent of the patients for whom code stroke is activated have stroke mimics, the most common being epilepsy. Our purpose was to evaluate the usefulness of multiparametric CT for differentiating between seizure-related symptoms and vascular events. We conducted a retrospective observational study; data were gathered prospectively during one year. We studied multiparametric CT images of patients admitted following code stroke activation and finally diagnosed with epilepsy. The study included a total of 11 patients; 36% were men and mean age was 74.5 years. Three patients had right hemisphere syndrome, 4 displayed left hemisphere syndrome, and the remaining 4 had isolated aphasia. Maximum time from symptom onset to multiparametric CT study was 8.16hours. Perfusion CT results were normal in 2 patients. Nine patients showed longer or shorter times to peak (Tmax); cerebral blood volume (CBV) and cerebral blood flow (CBF) maps varied. EEG was performed a maximum of 47.6hours after symptom onset. Four patients showed findings compatible with status epilepticus, 2 displayed focal epileptiform activity, and 5 showed post-ictal slowing ipsilateral to perfusion CT abnormalities. The most sensitive parameter for differentiating between stroke and epilepsy in our series was increased time to peak in multilobar cortical locations in the absence of large-vessel occlusion and basal ganglia involvement. Multiparametric CT is a fast, readily available, and useful tool for the differential diagnosis of acute-onset neurological signs of epileptic origin in patients initially attended after code stroke activation.

    Modern pacemakers are designed to allow patients to undergo magnetic resonance imaging (MRI) under a set of specific conditions. Aim of this study is to provide confirmatory evidence of safety and performance of a new pacing system (ImageReady™, Boston Scientific) in patients undergoing 1.5 and 3T MRI. Two prospective, nonrandomized, single-arm studies were designed to provide confirmatory data of no impact of MRI on device function, lead parameters, and patient conditions in subjects implanted with the system undergoing a clinically non-indicated 1.5T and 3T MRI, respectively. Device measurements were done within 1 hour before and after the scan and at 1 month follow-up. Thirty-two subjects underwent MRI visit (17 subjects with 1.5T MRI and 15 subjects with 3T MRI). There were no unanticipated adverse effects related to the pacemaker. Device measurements taken pre- and post-MRI scan did not show any clinical relevant change that could indicate an effect of the MRI on the device or at the lead-tissue interface (RV threshold change: 0.01 ± 0.13 V, P = 0.60; RA threshold change: 0.01 ± 0.11 V, P = 0.53; R wave change: -0.44 ± 1.73 mV, P = 0.36; R wave change: 0.12 ± 1.67 mV, P = 0.73), with data confirmed at 1-month follow-up visit. The study documented safety of the pacing system in the 1.5T and 3T MRI environment by showing no adverse events related to device or MRI scan. Additional data are required to cover the more complex scenarios involving different diagnostic needs, conditions of use, clinical conditions, and new emerging technologies. © 2017 Wiley Periodicals, Inc.

  13. A New Late Glacial Site in the Central Appalachians of Virginia. Preliminary Findings From Paleobotany, Palynology, and Geomorphology (United States)

    Schwartz, B. F.; Upchurch, G. R.; Willard, D. A.; Bernhardt, C. E.; Valella, P. A.


    Thick clay deposits in a recently identified paleo-lake bed in a central Appalachian karst system in Highland County, Virginia have yielded well-preserved pollen and macroflora that provide the opportunity to refine the understanding of Pleistocene climate, vegetation dynamics, and erosion in the region. A radiocarbon date of 22,000 14C yr B.P. on wood fragments near the top of the sequence establishes the age of the sediments. Pollen and plant macrofloras characteristic of modern boreal forests are present in sediments at this site. Pollen assemblages show a dominance of conifers, mostly Pinus banksiana and Picea, with Lycopodium as important ground cover. Leaf fossils sieved from the clay show a dominance of Picea needles and common dicot leaf fragments, suggesting that Pinus is either over-represented in the pollen flora or more distal to the paleo-lake. Macrofossil assemblages sieved from the clay contain a variety of non-leaf remains, including fruits, seeds, mosses, insects, feathers, and fungi. Test augering and geophysical results indicate that these clay deposits are at least 9m and perhaps as much as 15m thick. The amount and temporal distribution of sediment loads to the paleo-lake (a depositional environment) from the surrounding landscape (an erosional environment) will be modeled using analysis of sediment facies in and above (>12m) these clays, combined with sediment volume calculations and drainage basin analysis, and constrained by dates from the sediments themselves. Due to the rare occurrence of still-water depositional environments in the Appalachians, this site provides paleo-climate and sedimentological data that will refine regional models of landscape evolution and incision. This work also has implications for the development and modification of a significant karst system that surrounds and underlies the paleo-lake bed. The same karst system is responsible both for the formation of the paleo-lake (after the drain in a blind valley became

  14. Analyzing the impact of price subsidy on rice self-sufficiency level in Malaysia: A preliminary finding (United States)

    Rahim, Farah Hanim Abdul; Abidin, Norhaslinda Zainal; Hawari, Nurul Nazihah


    The Malaysian government had targeted for the rice industry in the country to achieve 100% rice self-sufficiency where Malaysia's rice self-sufficiency level (SSL) is currently at 65% to 75%. Thus, the government had implemented few policies to increase the rice production in Malaysia in order to meet the growing demand of rice. In this paper, the effect of price support on the rice production system in Malaysia is investigated. This study utilizes the system dynamics approach of the rice production system in Malaysia where the complexity of the factor is interrelated and changed dynamically through time. Scenario analysis was conducted using system dynamics model by making changes on the price subsidy to see its effect on the rice production and rice SSL. The system dynamics model provides a framework for understanding the effect of price subsidy on the rice self-sufficiency level. The scenario analysis of the model shows that a 50% increase in the price subsidy leads to a substantial increase in demand as the rice price drops. Accordingly, the local production increases by 15%. However, the SSL slightly decreases as the local production is insufficient to meet the large demand.

  15. What is the veterinary professional identity? Preliminary findings from web-based continuing professional development in veterinary professionalism. (United States)

    Armitage-Chan, E; Maddison, J; May, S A


    Professionalism and professional skills are increasingly being incorporated into veterinary curricula; however, lack of clarity in defining veterinary professionalism presents a potential challenge for directing course outcomes that are of benefit to the veterinary professional. An online continuing education course in veterinary professionalism was designed to address a deficit in postgraduate support in this area; as part of this course, delegates of varying practice backgrounds participated in online discussions reflecting on the implications of professional skills for their clinical practice. The discussions surrounding the role of the veterinary professional and reflecting on strengths and weaknesses in professional skills were analysed using narrative methodology, which provided an understanding of the defining skills and attributes of the veterinary professional, from the perspectives of those involved (i.e. how vets understood their own career identity). The veterinary surgeon was understood to be an interprofessional team member, who makes clinical decisions in the face of competing stakeholder needs and works in a complex environment comprising multiple and diverse challenges (stress, high emotions, financial issues, work-life balance). It was identified that strategies for accepting fallibility, and those necessary for establishing reasonable expectations of professional behaviour and clinical ability, are poorly developed.

  16. Preliminary findings of the effects of rivastigmine, an acetylcholinesterase inhibitor, on working memory in cocaine-dependent volunteers. (United States)

    Mahoney, James J; Kalechstein, Ari D; Verrico, Christopher D; Arnoudse, Nicholas M; Shapiro, Benjamin A; De La Garza, Richard


    Long-term cocaine use is a risk factor for the onset of neurocognitive impairment. This study sought to determine whether the cholinesterase inhibitor rivastigmine could improve neurocognitive performance in cocaine-dependent individuals. Cocaine-dependent individuals who were not seeking treatment at the time of enrollment in the study were randomly assigned to receive placebo (n=16), rivastigmine 3mg (n=13), or rivastigmine 6mg (n=12). The baseline neurocognitive assessment, which included measures of attention/information processing (as measured by the Continuous Performance Task-II (CPT-II)), verbal learning/episodic memory (as measured by the Hopkins Verbal Learning Test-Revised (HVLT-R)), and working memory (as measured by the Dual N-Back Task), was conducted prior to the administration of study medication (Day 0). The follow-up assessment was conducted on Day 8 after the participants had received rivastigmine or placebo for 7days (Day 2-8). Rivastigmine administration significantly improved performance on one measure of working memory span (mean n-back span). This study provides additional data showing that cocaine-associated neurocognitive impairment, specifically working memory deficits, can be remediated, at least to some degree. Copyright © 2013.

  17. Investigating the possibility of a syntactic impairment in the semantic variant of PPA using a constrained production task: Preliminary findings

    Directory of Open Access Journals (Sweden)

    Jennifer Cupit


    Sentence Type was run for three different measures of sentence production: accuracy on overall production, accuracy on verb morphology and ‘overall grammaticality’ (a measure we devised to reflect a sentence’s grammaticality, irrespective of its semantic content, for each of the three time points. Post hoc testing was performed using the Tukey-Kramer test. For all main effects and interactions, a p-value of less than 0.05 was considered significant. We found that both the nfvPPA and svPPA groups showed a syntactic impairment in this constrained sentence production task. However, the groups demonstrated a different pattern and progression of impairment, with the syntactic impairment initially being generally more severe and pervasive for participants with nfvPPA compared to participants with svPPA. Interestingly, the svPPA group demonstrated a syntactic impairment in the analysis of accuracy of verb morphology that was not observed in the analysis using the less stringent ‘overall grammaticality’ measure. This difference may mirror the differences observed when using constrained versus unconstrained tasks. Overall, the findings from this study contribute important information regarding the nature and progression of the language production impairment in the non-fluent and semantic variants of primary progressive aphasia.

  18. Preliminary findings on the reliability and validity of the Cantonese Birmingham Cognitive Screen in patients with acute ischemic stroke

    Directory of Open Access Journals (Sweden)

    Pan X


    .Results: Analyses showed high test–retest reliability and agreement across independent raters on the qualitative aspects of measurement. Significant correlations were observed between the subtests of the Cantonese BCoS and the other external cognitive tests, providing evidence for convergent validity of the Cantonese BCoS. The screen was also able to generate measures of cognitive functions that were relatively uncontaminated by the presence of aphasia.Conclusion: This study suggests good reliability and validity of the Cantonese version of the BCoS. The Cantonese BCoS is a very promising tool for the detection of cognitive problems in Cantonese speakers.

    Bixley, Morag; Jin, Lixian; Williamson, I.R.


    Abstract introduction Aphasia is a multimodality language difficulty experienced by people who have a left sided stroke. Speech and Language Therapists (SLTs) who work with People with Aphasia (PWA) often provide word finding therapy because wfd are one of the most debilitating effects of aphasic language loss. The majority of published word finding research uses mixed therapy techniques in which PWA practise accessing, using and combining sounds and words. This therapy trial is one of on...

  1. Integrated policy making in England for adults with long-term neurological conditions (LTNCs: some preliminary findings from a scoping study

    Directory of Open Access Journals (Sweden)

    Sylvia Bernard


    Full Text Available Introduction: Long-term neurological conditions are a major cause of disability in the UK and internationally. Their successful management, in order to enhance health and well-being, requires both sophisticated organisation across a number of health, social care and other service boundaries, and the real involvement of people with neurological conditions and members of their support networks. Policy development: This paper reports on part of the preliminary scoping phase of a study designed to evaluate the impact of the National Service Framework for long-term neurological conditions on integrated care. It describes current policies in England and reports on discussions with a range of people involved in the planning, provision or use of services, which took place during the scoping exercise. These interviews inform how policy affecting people with long-term neurological conditions has been received and implemented so far. Conclusion and discussion: Findings suggest that progress towards integrated service provision is patchy and slow. In the competing priorities within government policy, neurological conditions have tended to be marginalised, within healthcare policy generally and in initiatives to support people with long-term conditions in particular. The reasons for this are explored and will inform the next stages of the research.

  5. Open label smoking cessation with varenicline is associated with decreased glutamate levels and functional changes in anterior cingulate cortex: preliminary findings

    Directory of Open Access Journals (Sweden)

    Muriah Dawn Wheelock


    Full Text Available Rationale: Varenicline, the most effective single agent for smoking cessation, is a partial agonist at α4β2 nicotinic acetylcholine receptors. Increasing evidence implicates glutamate in the pathophysiology of addiction and one of the benefits of treatment for smoking cessation is the ability to regain cognitive control. Objective: To evaluate the effects of 12 week varenicline administration on glutamate levels in the dorsal anterior cingulate cortex (dACC and functional changes within the cognitive control network.Methods: We used single-voxel proton magnetic resonance spectroscopy (1H-MRS in the dACC and functional MRI (fMRI during performance of a Stroop color-naming task before and after smoking cessation with varenicline in 11 healthy smokers (open label design. Using the dACC as a seed region, we evaluated functional connectivity changes using a psychophysiological interaction (PPI analysis. Results: We observed a significant decrease in dACC glutamate + glutamine (Glx/Cr levels as well as significant blood oxygen level-dependent signal (BOLD decreases in the rostral ACC/medial orbitofrontal cortex and precuneus/posterior cingulate cortex. These BOLD changes are suggestive of alterations in default mode network (DMN function and are further supported by the results of the PPI analysis that revealed changes in connectivity between the dACC and regions of the DMN. Baseline measures of nicotine dependence and craving positively correlated with baseline Glx/Cr levels.Conclusions: These results suggest possible mechanisms of action for varenicline such as reduction in Glx levels in dACC and shifts in BOLD activities between large scale brain networks. They also suggest a role for ACC Glx in the modulation of behavior. Due to the preliminary nature of this study (lack of control group and small sample size, future studies are needed to replicate these findings.

  6. Motivation and incentives of rural maternal and neonatal health care providers: a comparison of qualitative findings from Burkina Faso, Ghana and Tanzania. (United States)

    Prytherch, Helen; Kagoné, Moubassira; Aninanya, Gifty A; Williams, John E; Kakoko, Deodatus C V; Leshabari, Melkidezek T; Yé, Maurice; Marx, Michael; Sauerborn, Rainer


    In Burkina Faso, Ghana and Tanzania strong efforts are being made to improve the quality of maternal and neonatal health (MNH) care. However, progress is impeded by challenges, especially in the area of human resources. All three countries are striving not only to scale up the number of available health staff, but also to improve performance by raising skill levels and enhancing provider motivation. In-depth interviews were used to explore MNH provider views about motivation and incentives at primary care level in rural Burkina Faso, Ghana and Tanzania. Interviews were held with 25 MNH providers, 8 facility and district managers, and 2 policy-makers in each country. Across the three countries some differences were found in the reasons why people became health workers. Commitment to remaining a health worker was generally high. The readiness to remain at a rural facility was far less, although in all settings there were some providers that were willing to stay. In Burkina Faso it appeared to be particularly difficult to recruit female MNH providers to rural areas. There were indications that MNH providers in all the settings sometimes failed to treat their patients well. This was shown to be interlinked with differences in how the term 'motivation' was understood, and in the views held about remuneration and the status of rural health work. Job satisfaction was shown to be quite high, and was particularly linked to community appreciation. With some important exceptions, there was a strong level of agreement regarding the financial and non-financial incentives that were suggested by these providers, but there were clear country preferences as to whether incentives should be for individuals or teams. Understandings of the terms and concepts pertaining to motivation differed between the three countries. The findings from Burkina Faso underline the importance of gender-sensitive health workforce planning. The training that all levels of MNH providers receive in

  7. Aerobic capacity with hybrid FES rowing in spinal cord injury: comparison with arms-only exercise and preliminary findings with regular training. (United States)

    Taylor, J Andrew; Picard, Glen; Widrick, Jeffrey J


    To determine the magnitude and range of increases in peak aerobic capacity with hybrid-functional electrical stimulation (FES) rowing versus arms-only rowing in persons with spinal cord injury. Comparison of graded exercise tests for peak responses during FES rowing and arms-only rowing. Preliminary data on adaptations to FES row training were gathered in a subset of individuals. Outpatient cardiovascular research laboratory. Six male patients with spinal cord injury (T4-T9, American Spinal Injury Association class A). METHODS OR INTERVENTION: Arms-only rowing was compared with FES rowing, in which the person who is exercising synchronizes the voluntarily controlled upper body movement with the FES-controlled leg movement via stimulation to the paralyzed leg muscles. A subgroup (n = 3) completed at least 6 months of a progressive FES row training exercise program with graded exercise tests every 6 months. Peak oxygen consumption, peak ventilation, peak respiratory exchange ratio, peak heart rate, and peak oxygen pulse. Peak oxygen consumption was greater during FES rowing than during arms-only rowing (20.0 ± 1.9 mL/kg/min versus 15.7 ± 1.5 mL/kg/min, P = .01). Peak ventilation was similar, whereas peak respiratory exchange ratio and peak heart rate tended to be lower (P = .14 and P = .19, respectively). As a result, oxygen pulse was greater by 35% during FES rowing. Two of the three persons who completed at least 6 months of FES row training demonstrated increases in aerobic capacity greater than those previously observed in able-bodied individuals. FES rowing may provide a more robust exercise stimulus for persons with spinal cord injury than most options currently available because of the greater aerobic demand.

  8. Filter-based measurements of UV-vis mass absorption cross sections of organic carbon aerosol from residential biomass combustion: Preliminary findings and sources of uncertainty (United States)

    Pandey, Apoorva; Pervez, Shamsh; Chakrabarty, Rajan K.


    Combustion of solid biomass fuels is a major source of household energy in developing nations. Black (BC) and organic carbon (OC) aerosols are the major PM2.5 (particulate matter with aerodynamic diameter smaller than 2.5 μm) pollutants co-emitted during burning of these fuels. While the optical nature of BC is well characterized, very little is known about the properties of light-absorbing OC (LAOC). Here, we report our preliminary findings on the mass-based optical properties of LAOC emitted from the combustion of four commonly used solid biomass fuels - fuel-wood, agricultural residue, dung-cake, and mixed - in traditional Indian cookstoves. As part of a pilot field study conducted in central India, PM2.5 samples were collected on Teflon filters and analyzed for their absorbance spectra in the 300-900 nm wavelengths at 1 nm resolution using a UV-Visible spectrophotometer equipped with an integrating sphere. The mean mass absorption cross-sections (MAC) of the emitted PM2.5 and OC, at 550 nm, were 0.8 and 0.2 m2 g-1, respectively, each with a factor of ~2.3 uncertainty. The mean absorption Ångström exponent (AǺE) values for PM2.5 were 3±1 between 350 and 550 nm, and 1.2±0.1 between 550 and 880 nm. In the 350-550 nm range, OC had an AǺE of 6.3±1.8. The emitted OC mass, which was on average 25 times of the BC mass, contributed over 50% of the aerosol absorbance at wavelengths smaller than 450 nm. The overall OC contribution to visible solar light (300-900 nm) absorption by the emitted particles was 26-45%. Our results highlight the need to comprehensively and accurately address: (i) the climatic impacts of light absorption by OC from cookstove emissions, and (ii) the uncertainties and biases associated with variability in biomass fuel types and combustion conditions, and filter-based measurement artifacts during determination of MAC values.

  10. Sight for seniors: a summary of findings and challenges to providing community-based eye care to low-income seniors. (United States)

    Winters, Janis Ecklund; Pihos, Andria M


    The Sight for Seniors (SFS) program was developed to provide eye care and eyeglasses to low-income seniors. Residents from a Chicago Housing Authority senior development participated in SFS. A community liaison promoted SFS and enrolled residents. Patients received transportation, eye care that took place at the Illinois Eye Institute, and spectacles at no out-of-pocket cost. Eighty-nine patients were seen. The mean age was 71.8 years (standard deviation, 7.2). Fifty-six (62.9%) patients were women, and 73 (82.0%) were black. The last eye examination was reported within a year by 16 (18.0%), and 44 reported that their last medical examination was within 1 year. All patients required and received eyeglasses. Seventy-four (83.1%) improved Snellen distance visual acuity by 1 line or more and 26 (29.2%) by 3 lines or more. Twenty (22.5%) had glaucoma, and 9 had diabetic retinopathy. Sixty-three (70.8%) reported a history of hypertension (HTN) and 33 (37.1%) type 2 diabetes mellitus (DM). HTN was controlled in 4 (15%) of those with HTN and DM and 12 (34.3%) of those with HTN but not DM. Last reported eye examination, medical history, and examination findings support the need for eye care in this population. These findings are applicable to similar populations.

    Background To compare {sup 18}F-fluoro-2-deoxdeoxyglucose (FDG) positron emission tomography (PET) related parameters of primary colon or sigmoid cancer (CSC) with pathological findings. Methods Seventy-seven CSC patients who have undergone preoperative PET computed tomograms (PET/CT) are included in this study. Maximum PET-based tumor length (TL) and tumor width (TW) are determined using several auto-segmentation methods, and various thresholds of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) are measured. The PET-based TL and TW are compared with maximum pathological length and width on the pathological specimen. Results Using a 30% threshold level for maximum uptake of TL (TL30%) and TW (TW30%) yield results that provide an optimal match with maximum pathological length (R = 0.81, p < 0.001) and width (R = 0.70, p < 0.001). TW30% was an independent factor for predicting pathological T3 or T4 stages (OR = 1.26, 95% CI = 1.07–1.47, p = 0.01). The receiver-operating characteristic curves show MTV at a fixed threshold of 40% maximum uptake (MTV40%), and TW30% achieved better correlation with the advanced pathological T stage. No associations with positive N stage were observed. Conclusion Pretreatment PET/CT is a useful tool for predicting the final pathological findings for CSC patients requiring surgical procedures.

  13. Experiences of Kenyan healthcare workers providing services to men who have sex with men: qualitative findings from a sensitivity training programme

    Directory of Open Access Journals (Sweden)

    Elise M van der Elst


    Full Text Available Introduction: Men who have sex with men (MSM in Kenya are at high risk for HIV and may experience prejudiced treatment in health settings due to stigma. An on-line computer-facilitated MSM sensitivity programme was conducted to educate healthcare workers (HCWs about the health issues and needs of MSM patients. Methods: Seventy-four HCWs from 49 ART-providing health facilities in the Kenyan Coast were recruited through purposive sampling to undergo a two-day MSM sensitivity training. We conducted eight focus group discussions (FGDs with programme participants prior to and three months after completing the training programme. Discussions aimed to characterize HCWs’ challenges in serving MSM patients and impacts of programme participation on HCWs’ personal attitudes and professional capacities. Results: Before participating in the training programme, HCWs described secondary stigma, lack of professional education about MSM, and personal and social prejudices as barriers to serving MSM clients. After completing the programme, HCWs expressed greater acknowledgement of MSM patients in their clinics, endorsed the need to treat MSM patients with high professional standards and demonstrated sophisticated awareness of the social and behavioural risks for HIV among MSM. Conclusions: Findings provide support for this approach to improving health services for MSM patients. Further efforts are needed to broaden the reach of this training in other areas, address identified barriers to HCW participation and evaluate programme effects on patient and HCW outcomes using rigorous methodology.

    Directory of Open Access Journals (Sweden)

    Charles M. Schweik


    Full Text Available This paper presents some of the findings from a 5-year empirical study of FOSS (free/libre and open source software commons, completed in 2011.  FOSS projects are Internet-based common property regimes where the project source code is developed over the Internet. The resulting software is generally distributed with a license that provides users with the freedoms to access, use, read, modify and redistribute the software. In this study we used three different and very large datasets (approximately 107,000; 174,000 and 1400 cases respectively with information on FOSS projects residing in, one of the largest, if not the largest, FOSS repository in the world. We employ various quantitative methods to uncover factors that lead some FOSS projects to ongoing collaborative success, while others become abandoned. After presenting some of our study’s results, we articulate the collaborative “story” of FOSS that emerged. We close the paper by discussing some key findings that can contribute to a general theory of Internet-based collective-action and FOSS-like forms of digital online commons.

  15. Patterns of patient and healthcare provider viewpoints regarding participation in HIV cure-related clinical trials. Findings from a multicentre French survey using Q methodology (ANRS-APSEC.

    Directory of Open Access Journals (Sweden)

    Christel Protière

    Full Text Available Despite huge advances in the fight against HIV concerning diagnosis, clinical efficacy of antiretroviral treatments (ART, patient survival and quality of life, there is still no cure. Recent developments in HIV cure research have opened the way for clinical trials which could lead to a temporary or definitive end to ART. However, ethical questions exist about related trial-participation risks. The main goal of the ANRS-APSEC survey was, using Q-methodology, to investigate the viewpoints of people living with HIV (PLWH and HIV healthcare providers (HHP regarding motivations for and barriers to participation in HIV Cure-related clinical trials (HCRCT.Thirty-three statements were defined encompassing seven dimensions: treatment and follow-up; risks; benefits; patient-physician relationship; beliefs and attitudes; information; target population. Forty-one PLWH and 41 HHP from five French HIV services were asked to rank-order the statements.Five main viewpoints were elicited from "the most motivated" to "the most reluctant" vis-à-vis HCRCT participation. All placed importance on the wish to participate in HIV research. This result is in line with the HIV-specific culture of joint mobilization. For some viewpoints, the motivation to participate in/propose HCRCT was primarily conditioned by side-effects and/or by constraints, which overall were more accepted by PLWH than HHP. Some viewpoints placed particular importance on HCRCT recruitment strategies. Finally, some expressed a high acceptance of risks and constraints but emphasized the need for information.HIV cure research clinical trials (HCRCT constitute a risky yet unavoidable step towards the goal of finding a cure. To improve future HCRCT and informed consent designs, based on PLWH and HHP preferences and expectations, we need greater knowledge about how these populations perceive the risks and the benefits of HCRCT. Our results confirmed the importance of careful, studied HCRCT design

    Few studies have assessed the use of osteopathic manipulative treatment (OMT) and subsequent patient-reported outcomes. To assess the current use of OMT and associated patient-reported outcomes. A retrospective medical record review and a prospective observational study. Two university-based sites and their clinics associated with the practice-based research network DO-Touch.NET. Patients aged 18 years or older who received OMT. Medical records from 2007 were retrospectively reviewed to identify conditions being managed with OMT. From 2008 to 2010, patients were recruited before seeing their physicians. Questionnaires were distributed to patients and physicians, and information including demographics, chief complaints, symptom severity, current and past treatments, interference of symptoms with quality of life, physical examination findings, diagnoses, OMT performed, and immediate patient response to OMT was collected. A subset of patients provided data on symptom severity and frequency and other treatments daily for the 7 days after OMT. On day 7, symptom interference with quality of life was reassessed. Retrospective data were collected from 2569 office visits, and prospective data were collected from 299 office visits (patient age range, 18-93 years). In the medical record review, 17 of the top 25 diagnoses (68%) were related to musculoskeletal conditions. In the prospective study, 18 of the top 24 medical diagnoses (75%) were related to musculoskeletal conditions. Immediately after OMT, patients at 271 of 296 office visits (92%) felt better or much better; those at 5 (osteopathic research and define evidence-based standards for OMT practice and training.

  17. Experiences and Attitudes of Primary Care Providers Under the First Year of ACA Coverage Expansion: Findings from the Kaiser Family Foundation/Commonwealth Fund 2015 National Survey of Primary Care Providers. (United States)


    A new survey from The Kaiser Family Foundation and The Commonwealth Fund asked primary care providers--physicians, nurse practitioners, and physician assistants--about their views of and experiences with the Affordable Care Act (ACA) and other changes in health care delivery and payment, as well as their thoughts on the future of primary care. In this first brief based on the survey, many providers reported seeing an increased number of patients since the coverage expansions went into effect, but not an accompanying compromise in quality of care. A large majority of primary care providers are satisfied with their medical practice, but a substantial percentage of physicians expressed pessimism about the future of primary care. Similar to the population overall, providers' views of the ACA are divided along party lines. A second brief will report on providers' reactions to other changes occurring in primary care delivery and payment.

  18. Parental Substance Abuse As an Early Traumatic Event. Preliminary Findings on Neuropsychological and Personality Functioning in Young Drug Addicts Exposed to Drugs Early. (United States)

    Parolin, Micol; Simonelli, Alessandra; Mapelli, Daniela; Sacco, Marianna; Cristofalo, Patrizia


    Parental substance use is a major risk factor for child development, heightening the risk of drug problems in adolescence and young adulthood, and exposing offspring to several types of traumatic events. First, prenatal drug exposure can be considered a form of trauma itself, with subtle but long-lasting sequelae at the neuro-behavioral level. Second, parents' addiction often entails a childrearing environment characterized by poor parenting skills, disadvantaged contexts and adverse childhood experiences (ACEs), leading to dysfunctional outcomes. Young adults born from/raised by parents with drug problems and diagnosed with a Substance Used Disorder (SUD) themselves might display a particularly severe condition in terms of cognitive deficits and impaired personality function. This preliminary study aims to investigate the role of early exposure to drugs as a traumatic event, capable of affecting the psychological status of young drug addicts. In particular, it intends to examine the neuropsychological functioning and personality profile of young adults with severe SUDs who were exposed to drugs early in their family context. The research involved three groups, each consisting of 15 young adults (aged 18-24): a group of inpatients diagnosed with SUDs and exposed to drugs early, a comparison group of non-exposed inpatients and a group of non-exposed youth without SUDs. A neuropsychological battery (Esame Neuropsicologico Breve-2), an assessment procedure for personality disorders (Shedler-Westen Assessment Procedure-200) and the Symptom CheckList-90-Revised were administered. According to present preliminary results, young drug addicts exposed to drugs during their developmental age were characterized by elevated rates of neuropsychological impairments, especially at the expense of attentive and executive functions (EF); personality disorders were also common but did not differentiate them from non-exposed youth with SUDs.

    Directory of Open Access Journals (Sweden)

    Senbanjo Richard


    Full Text Available Abstract Background Within the UK, injecting in the femoral vein (FV, often called 'groin injecting', is a serious cause of risk and harm. This study aimed to use ultrasound scanning as a means to engage groin injectors (GIs, examine their femoral injecting sites and assess their venous health, with the intention of developing improved responses. Methods Between September 2006 and March 2009, GIs attending a network of community drug treatment centres in South East England were invited to attend an ultrasound 'health-check' clinic. This paper provides a narrative account of the scanning procedure and operation of the service, with descriptive statistical analysis of GIs who attended. The analysis uses a structured, specially-developed clinical data set that incorporates a categorisation for the severity of FV damage. Case studies using ultrasound images and a link to a video are provided to illustrate the range of presentations encountered and the categorisations used for severity. Results A total of 160 groin scans (76 bilateral and 8 unilateral were performed in 84 GIs. The majority were men (69.0% and the mean age of the sample was 36.8 years. The mean duration of drug use and injecting drug use was 19.7 years and 13.8 years, respectively. FV damage at the injecting site in the right groin was graded as minimal in 20 patients (25%, moderate in 27 (33.8%, severe in 16 (20.0% and very-severe in 17 (21.3%. Corresponding figures for left FV were 24 (30.0%, 22 (27.5%, 18 (22.5% and 16 (20.0%. Wide variation was observed in the time to the development of these grades of FV damage. Conclusions Modern, portable ultrasound scanners make it possible to examine the venous health of GIs in community treatment settings. Ultrasound scanning identified extensive FV damage, much hitherto-unrecognised in this population. These findings should further alert clinicians, policy-makers and patients to the urgent need for effective harm reduction responses to GI

    Blaine, Rachel E; Davison, Kirsten K; Hesketh, Kathryn; Taveras, Elsie M; Gillman, Matthew W; Benjamin Neelon, Sara E


    Identifying characteristics associated with the Institute of Medicine's (IOM) recommended feeding practices among infant and toddler care providers in child care centers could help in preventing childhood obesity. In 2009, at baseline in a pilot intervention study of 29 licensed Massachusetts child care centers with at least 50% of enrolled children identified as racial minorities, 57 infant and 109 toddler providers completed feeding questionnaires. To assess provider adherence to six IOM-recommended behaviors, we used cluster-adjusted multivariable logistic regression models including provider type (infant or toddler), race, education, and center Child and Adult Care Food Program (CACFP) participation. In multivariable analysis, CACFP participation was associated with providers sitting with children at meals (odds ratio [OR], 5.2; 95% confidence interval [CI], 1.2-21.7), offering fruits and vegetables (OR, 3.3; 95% CI 1.7-6.2), and limiting fast food (OR, 3.5; 95% CI, 1.8-6.7). Providers at centers serving meals family style were less likely to allow children to leave food unfinished (OR, 0.27; 95% CI, 0.09-0.77). Infant providers were more likely than toddler providers to sit with children at meals (OR, 6.98; 95% CI, 1.51-32.09), allow children to eat when hungry (OR, 3.50; 95% CI, 1.34-9.16), and avoid serving sugary (OR, 8.74; 95% CI, 3.05-25.06) or fast foods (OR, 11.56; 95% CI, 3.20-41.80). CACFP participation may encourage IOM-recommended feeding practices among infant and toddler providers. Child care providers may benefit from education about how to feed infants and toddlers responsively, especially when offering foods family style. Future research should explore ways to promote child-centered feeding practices, while addressing barriers to providing children with nutrient-rich foods.

    Viergever, Roderik F; West, Haley; Borland, Rosilyne; Zimmerman, Cathy


    Human trafficking is a crime that commonly results in acute and chronic physical and psychological harm. To foster more informed health sector responses to human trafficking, training sessions for health care providers were developed and pilot-tested in the Middle East, Central America, and the Caribbean. This study presents the results of an investigation into what health care providers knew and needed to know about human trafficking as part of that training program. Participants attended one of seven two-day training courses in Antigua and Barbuda, Belize, Costa Rica, Egypt, El Salvador, Guyana, and Jordan. We assessed participants' knowledge about human trafficking and opinions about appropriate responses in trafficking cases via questionnaires pre-training, and considered participant feedback about the training post-training. 178 participants attended the trainings. Pre-training questionnaires were completed by 165 participants (93%) and post-training questionnaires by 156 participants (88%). Pre-training knowledge about health and human trafficking appeared generally high for topics such as the international nature of trafficking and the likelihood of poor mental health outcomes among survivors. However, many participants had misconceptions about the characteristics of trafficked persons and a provider's role in responding to cases of trafficking. The most valued training components included the "Role of the Health Provider," "Basic Definitions and Concepts," and "Health Consequences of Trafficking." Training health care providers on caring for trafficked persons has the potential to improve practitioners' knowledge about human trafficking and its health consequences, and to increase safe practices when responding in cases of trafficking. This study provides lessons for the design of training programs on human trafficking that aim to help health care providers identify and refer victims, and provide care for survivors.

  2. Explaining unexplained pain to fibromyalgia patients: finding a narrative that is acceptable to patients and provides a rationale for evidence based interventions


    Hyland, ME; Hinton, C.; Hill, C.; Whalley, B; Jones,RC; Davies, AF


    As the cause of fibromyalgia is controversial, communicating with patients can be challenging, particularly if the patient adopts the narrative ‘I am damaged and so I need a more powerful pain killer’. Research shows that providing patients with alternative narratives can be helpful, but it remains unclear what particular narratives are most acceptable to patients and at the same time provide a rationale for evidence based psychological and exercise interventions. This article described the d...

    Hswen, Yulin; Naslund, John A; Brownstein, John S; Hawkins, Jared B


    Digital technologies hold promise for supporting the detection and management of schizophrenia. This exploratory study aimed to generate an initial understanding of whether patterns of communication about depression and anxiety on popular social media among individuals with schizophrenia are consistent with offline representations of the illness. From January to July 2016, posts on Twitter were collected from a sample of Twitter users who self-identify as having a schizophrenia spectrum disorder (n = 203) and a randomly selected sample of control users (n = 173). Frequency and timing of communication about depression and anxiety were compared between groups. In total, the groups posted n = 1,544,122 tweets and users had similar characteristics. Twitter users with schizophrenia showed significantly greater odds of tweeting about depression compared with control users (OR = 2.69; 95% CI 1.76-4.10), and significantly greater odds of tweeting about anxiety compared with control users (OR = 1.81; 95% CI 1.20-2.73). This study offers preliminary insights that Twitter users with schizophrenia may express elevated symptoms of depression and anxiety in their online posts, which is consistent with clinical characteristics of schizophrenia observed in offline settings. Social media platforms could further our understanding of schizophrenia by informing a digital phenotype and may afford new opportunities to support early illness detection.

    Despite 90 % of glioblastoma (GBM) recurrences occurring in the peritumoral brain zone (PBZ), its contribution in patient survival is poorly understood. The current study leverages computerized texture (i.e. radiomic) analysis to evaluate the efficacy of PBZ features from pre-operative MRI in predicting long- (>18 months) versus short-term (<7 months) survival in GBM. Sixty-five patient examinations (29 short-term, 36 long-term) with gadolinium-contrast T{sub 1w}, FLAIR and T{sub 2w} sequences from the Cancer Imaging Archive were employed. An expert manually segmented each study as: enhancing lesion, PBZ and tumour necrosis. 402 radiomic features (capturing co-occurrence, grey-level dependence and directional gradients) were obtained for each region. Evaluation was performed using threefold cross-validation, such that a subset of studies was used to select the most predictive features, and the remaining subset was used to evaluate their efficacy in predicting survival. A subset of ten radiomic 'peritumoral' MRI features, suggestive of intensity heterogeneity and textural patterns, was found to be predictive of survival (p = 1.47 x 10{sup -5}) as compared to features from enhancing tumour, necrotic regions and known clinical factors. Our preliminary analysis suggests that radiomic features from the PBZ on routine pre-operative MRI may be predictive of long- versus short-term survival in GBM. (orig.)

    Full Text Available The aim of this preliminary study was to evaluate the effect of low-dose oral vitamin D in combination with current disease-modifying therapy on the prevention of progression of relapsing-remitting multiple sclerosis (RRMS. A phase II double-blind placebo-controlled randomized clinical trial conducted between October 2007 and October 2008 included 50 patients with confirmed RRMS aged 25 to 57 years and normal serum 25-hydroxyvitamin D. They were randomly allocated to receive 12 months of treatment with either escalating calcitriol doses up to 0.5 μg/day or placebo combined with disease-modifying therapy. Response to treatment was assessed at eight-week intervals. In both groups, the mean relapse rate decreased significantly (P<0.001. In the 25 patients treated with placebo, the mean (SD Expanded Disability Status Scale (EDSS increased from 1.70 (1.21 at baseline to 1.94 (1.41 at the end of study period (P<0.01. Average EDSS and relapse rate at the end of trial did not differ between groups. Adding low-dose vitamin D to routine disease-modifying therapy had no significant effect on the EDSS score or relapse rate. A larger phase III multicenter study of vitamin D in RRMS is warranted to more assess the efficacy of this intervention.

  6. A prospective longitudinal study of neuropsychological and psychosocial factors in asymptomatic individuals at risk for HTLV-III/LAV infection in a methadone program: preliminary findings. (United States)

    Silberstein, C H; McKegney, F P; O'Dowd, M A; Selwyn, P A; Schoenbaum, E; Drucker, E; Feiner, C; Cox, C P; Friedland, G


    To test the hypothesis that cognitive impairment may be present early in the course of HTLV-III/LAV infection, intravenous drug abusers (IDVAs) without overt symptoms of AIDS related illness were tested with standard neuropsychological and psychosocial measures. This study is the baseline for a prospective longitudinal study of the natural history of HTLV-III/LAV infection in this high risk population. Of 211 subjects initially evaluated, 70 (33%) were HTLV-III/LAV seropositive and 141 (67%) were seronegative. At the baseline, by univariate analysis, the seropositive IVDAs were significantly (p less than .05) more impaired than seronegatives on 4 of 8 measures: Finger Tapping--dominant, hand, Digit Span Forward, Trail making A and WAIS-Similarities. However, by multivariate analysis the seropositives were significantly more impaired only on the WAIS-Similarities and Wechsler--Associative Learning tests. Multiple factors such as drug use and psychological stress may have influenced test performance. These preliminary results, however, suggest that seropositive IVDAs may show evidence of impaired neuropsychological function even in the absence of AIDS related symptoms and are consistent with the hypothesis of the early neurotropism of HTLV-III/LAV.

  7. Application example: Preliminary Results of ISOLA use to find moment tensor solutions and centroid depth applied to aftershocks of Mw=8.8 February 27 2010, Maule Earthquake (United States)

    Nacif, S. V.; Sanchez, M. A.


    We selected seven aftershocks from Maule earthquake between 33.5°S to 35°S from May to September to find single source inversion. The data were provided by XY Chile Ramp Experiment* which was deployed after great Maule earthquake. Waveform data are from 13 broad band stations chosen from the 58 broad band stations deployed by IRIS-PASCAL from April to September 2010. Stations are placed above the normal subduction section south of ~33.5°S. Events were located with an iterative software called Hypocenter using one dimensional local model, obtained above for the forearc region between 33°S to 35°S. We used ISOLA which is a fortran code with a Matlab interface to obtain moment tensors solutions, optimum position and time of the subevents. Values depth obtained by a grid search of centroid position show range values which are compatibles with the interplate seismogenic zone. Double-Couple focal mechanism solutions (Figure 1) show 4 thrust events which can be associated with that zone. However, only one of them has strike, dip and rake of 358°, 27° and 101 respectively, appropriate to be expected for interplate seismogenic zone. On the other hand, the other 3 events show strike and normal double-couple focal mechanism solutions (Figure 1). This last topic makes association to those events to the contact of the Nazca and South American plate difficult. Nevertheless, in a first stage, their depths may allow possibility of an origin there. * The facilities of the IRIS Data Management System, and specifically the IRIS Data Management Center, were used for access to waveform, metadata or products required in this study.

  10. Explaining unexplained pain to fibromyalgia patients: finding a narrative that is acceptable to patients and provides a rationale for evidence based interventions. (United States)

    Hyland, Michael E; Hinton, Claire; Hill, Charlotte; Whalley, Ben; Jones, Rupert Cm; Davies, Anthony F


    As the cause of fibromyalgia is controversial, communicating with patients can be challenging, particularly if the patient adopts the narrative 'I am damaged and so I need a more powerful pain killer'. Research shows that providing patients with alternative narratives can be helpful, but it remains unclear what particular narratives are most acceptable to patients and at the same time provide a rationale for evidence based psychological and exercise interventions. This article described the development of a new narrative and the written comments made about the narrative by fibromyalgia patients. The narrative derives from a complexity theory model and provides an alternative to biogenic and psychogenic models. The model was presented to 15 patients whose comments about comprehensibility led to the final format of the narrative. In the final form, the body is presented as 'a very, very clever computer' where fibromyalgia is caused by a software rather than a hardware problem. The software problem is caused by the body adapting when people have to 'keep going' despite 'stop signals', such as pain and fatigue. The narrative provides a rationale for engaging in psychological and exercise interventions as a way of correcting the body's software. This way of explaining fibromyalgia was evaluated by a further 25 patients attending a 7-week 'body reprogramming' intervention, where the therapy was presented as correcting the body's software, and included both exercise and psychological components. Attendance at the course was 85%. Thematic analysis of written patient feedback collected after each session showed that patients found the model believable and informative, it provided hope and was empowering. Patients also indicated that they had started to implement lifestyle change with perceived benefit. Fibromyalgia patients appear to respond positively to a technology-derived narrative based on the analogy of the body as a computer.

  11. A Preliminary Investigation of the Prevalence of Corporal Punishment of Children and Selected Co-occurring Behaviours in Households on New Providence, The Bahamas

    Directory of Open Access Journals (Sweden)

    Adderley, Latanya


    Full Text Available The purpose of this study was to examine the link between violence in homes, focusing on corporal punishment of children as a means of discipline, and other behaviours (including sexual abuse, illegal drug use, domestic violence, hitting of pets which may be a cause for concern. This paper reports the results of a survey of 933 people and 12 case studies. Violence, physical or domestic, occurred in 62% of survey participants’ homes. The survey indicated that in respondents’ homes many children were physically hurt as a means of discipline. Children were spanked in 77% of homes with children, pets were hit in 25% of homes with pets, and domestic violence was found in 23% of homes. These findings suggest that those who use violence in their homes may not understand the wider and longer-term consequences of their actions for both victims and society. Case study participants seemed to view only severe physical violence as abuse. They also appeared reluctant to report abuse to the authorities which can hamper the efforts to curb violence in homes.

  12. Technology for the oil spills clean-up which provides preliminary accumulation of sorbents into the area of emergence and localization oil spills

    Directory of Open Access Journals (Sweden)



    Full Text Available Introduction: The implementation of measures for the prevention and spill of dangerous goods is an important aspect of sustainable development of railway transport. oil spills accident are the most dangerous. They are accompanied by significant pollution of all environmental objects. Studying and development of oil localization and clean-up technologies of such accidents is an important problem of environmental protection to modern conditions of railway transport development. The purpose: to improve the effectiveness of traditional methods of oil spill elimination and the development of new clean-up technologies adapted to the real conditions of the railway transport of Ukraine. Methods: To achieve the research purposes was used analysis of material flows, typical for places emergence and localization of the oil spill on the railways. Results: Analysis of standard technological scheme for the oil spills eliminations has shown that the most difficult task of effective clean-up surfaces is the timely delivery of oil sorbents and special equipment to the area spill containment. The general effectiveness of the elimination activities specifies the time from the beginning contact of dangerous goods with environmental objects to the absorption it into the structure of sorbent . Us was developed the technological scheme of oil spill elimination. This scheme provide a permanent and fast access to the sorbents into the oil spill localization area. It was proposed to device that allows you to transport the sorbent into sorption booms directly on the tank for transportation of petroleum products. Conclusions: Preventative accumulation of sorbents to the oil spill elimination into the localization area provides the organizational and operational simplicity of all stages of clean-up technology. Technical and economic assessment shows that the proposed technology is effective, technologically feasible and economically competitive.

  13. The impact of the social and physical environments on parent-healthcare provider relationships when a child dies in PICU: Findings from a grounded theory study. (United States)

    Butler, Ashleigh E; Copnell, Beverley; Hall, Helen


    This study explores the influences of the paediatric intensive care environment on relationships between parents and healthcare providers when children are dying. It forms part of a larger study, investigating parental experiences of the death of their child in intensive care. Constructivist grounded theory. Four Australian paediatric intensive care units. Audio-recorded, semi-structured interviews were conducted with twenty-six bereaved parents. Data were analysed using the constant comparison and memoing techniques common to grounded theory. The physical and social environment of the intensive care unit influenced the quality of the parent-healthcare provider relationship. When a welcoming, open environment existed, parents tended to feel respected as equal and included members of their child's care team. In contrast, environments that restricted parental presence or lacked resources for parental self-care could leave parents feeling like 'watchers', excluded from their child's care. The paediatric intensive care unit environment either welcomes and includes parents of dying children into the care team, or demotes them to the status of 'watcher'. Such environments significantly influence the relationships parents form with healthcare staff, their ability to engage in elements of their parental role, and their experiences as a whole.

  15. Therapeutic factors and language patterns in group therapy application of computer-assisted text analysis to the examination of microprocesses in group therapy: preliminary findings. (United States)

    Fontao, Maria Isabel; Mergenthaler, Erhard


    The aim of this single-case-design study was to examine the relationships between therapeutic factors in group therapy and the language features of the group dialogue. Forty-two transcripts from a group treatment were investigated. Emotion-abstraction patterns (EAPs) were identified for the group as a whole using computer-assisted text analysis, and therapeutic factors were rated by external judges using the Kiel Group Psychotherapy Process Scale. Significant positive relationships were found between insight and the EAP connecting and between catharsis and the EAP experiencing. Interpersonal learning-output, catharsis, and self-disclosure showed higher scores in connection with the therapeutic cycle, which, according to the therapeutic cycle model, represents a sequence of EAP related to a successful therapeutic process. The current findings show that the use of EAPs allows the identification of key moments in a group therapy process.

  16. Increased chromosomal breakage in Tourette syndrome predicts the possibility of variable multiple gene involvement in spectrum phenotypes: Preliminary findings and hypothesis

    Energy Technology Data Exchange (ETDEWEB)

    Gericke, G.S.; Simonic, I.; Cloete, E.; Buckle, C. [Univ. of Pretoria (South Africa)] [and others


    Increased chromosomal breakage was found in 12 patients with DSM-IV Tourette syndrome (TS) as compared with 10 non-TS control individuals with respect to untreated, modified RPM1-, and BrdU treated lymphocyte cultures (P < 0.001 in each category). A hypothesis is proposed that a major TS gene is probably connected to genetic instability, and associated chromosomal marker sites may be indicative of the localization of secondary genes whose altered expression could be responsible for associated comorbid conditions. This concept implies that genes influencing higher brain functions may be situated at or near highly recombigenic areas allowing enhanced amplification, duplication and recombination following chromosomal strand breakage. Further studies on a larger sample size are required to confirm the findings relating to chromosomal breakage and to analyze the possible implications for a paradigmatic shift in linkage strategy for complex disorders by focusing on areas at or near unstable chromosomal marker sites. 32 refs., 1 tab.

  17. Borderline personality disorder features, emotion dysregulation and non-suicidal self-injury: Preliminary findings in a sample of community-dwelling Italian adolescents. (United States)

    Somma, Antonella; Sharp, Carla; Borroni, Serena; Fossati, Andrea


    In order to assess the relationships among borderline personality disorder features, non-suicidal self-injury (NSSI) and emotion dysregulation, 122 community-dwelling Italian adolescents were administered by the Italian translations of the Borderline Personality Features Scale for Children-11, the Deliberate Self-Harm Inventory and the Difficulties in Emotion Regulation Scale (DERS). Regression models showed that both Deliberate Self-Harm Inventory (DSHI) and DERS scores significantly predicted Borderline Personality Features Scale for Children-11 total score; moreover, the DSHI total score significantly predicted the DERS total score. Our findings suggest that borderline personality features in adolescence are moderately, albeit significantly related to NSSI, and that emotion dysregulation does not completely account for the association between borderline personality features and NSSI, although it seems to explain a non-trivial proportion of this relationship.

  18. Histogram Analysis of T1-Weighted, T2-Weighted, and Postcontrast T1-Weighted Images in Primary CNS Lymphoma: Correlations with Histopathological Findings-a Preliminary Study. (United States)

    Meyer, Hans-Jonas; Schob, Stefan; Münch, Benno; Frydrychowicz, Clara; Garnov, Nikita; Quäschling, Ulf; Hoffmann, Karl-Titus; Surov, Alexey


    Previously, some reports mentioned that magnetic resonance imaging (MRI) can predict histopathological features in primary CNS lymphoma (PCNSL). The reported data analyzed diffusion-weighted imaging findings. The aim of this study was to investigate possible associations between histopathological findings, such as tumor cellularity, nucleic areas and proliferation index Ki-67, and signal intensity on T1-weighted and T2-weighted images in PCNSL. For this study, 18 patients with PCNSL were retrospectively investigated by histogram analysis on precontrast and postcontrast T1-weighted and fluid-attenuated inversion recovery (FLAIR) images. For every patient, histopathology parameters, nucleic count, total nucleic area, and average nucleic area, as well as Ki-67 index, were estimated. Correlation analysis identified several statistically significant associations. Skewness derived from precontrast T1-weighted images correlated with Ki-67 index (p = - 0.55, P = 0.028). Furthermore, entropy derived from precontrast T1-weighted images correlated with average nucleic area (p = 0.53, P = 0.04). Several parameters from postcontrast T1-weighted images correlated with nucleic count: maximum signal intensity (p = 0.59, P = 0.017), P75 (p = 0.56, P = 0.02), and P90 (p = 0.52, P = 0.04) as well as SD (p = 0.58, P = 0.02). Maximum signal intensity derived from FLAIR sequence correlated with nucleic count (p = 0.50, P = 0.03). Histogram-derived parameters of conventional MRI sequences can reflect different histopathological features in PSNCL.

    Duerr, R.; Thessen, A.; Jenkins, C. J.; Palmer, M.; Myers, S.; Ramdeen, S.


    The ability to quickly find, easily use and effortlessly integrate data from a variety of sources is a grand challenge in Earth sciences, one around which entire research programs have been built. A myriad of approaches to tackling components of this challenge have been demonstrated, often with some success. Yet finding, assessing, accessing, using and integrating data remains a major challenge for many researchers. A technology that has shown promise in nearly every aspect of the challenge is semantics. Semantics has been shown to improve data discovery, facilitate assessment of a data set, and through adoption of the W3C's Linked Data Platform to have improved data integration and use at least for data amenable to that paradigm. Yet the creation of semantic resources has been slow. Why? Amongst a plethora of other reasons, it is because semantic expertise is rare in the Earth and Space sciences; the creation of semantic resources for even a single discipline is labor intensive and requires agreement within the discipline; best practices, methods and tools for supporting the creation and maintenance of the resources generated are in flux; and the human and financial capital needed are rarely available in the Earth sciences. However, other fields, such as biomedicine, have made considerable progress in these areas. The NSF-funded ClearEarth project is adapting the methods and tools from these communities for the Earth sciences in the expectation that doing so will enhance progress and the rate at which the needed semantic resources are created. We discuss progress and results to date, lessons learned from this adaptation process, and describe our upcoming efforts to extend this knowledge to the next generation of Earth and data scientists.

  20. Characteristics of newly immigrated, Spanish-speaking Latinos who use the pediatric emergency department: preliminary findings in a secondary migration city. (United States)

    Vaughn, Lisa M; Jacquez, Farrah


    This study aimed to assess Latino immigrant usage, access, and reason for coming to the pediatric emergency department (PED) and clarify parental perceptions, barriers, and concerns regarding Latino children's health. Interviews and questionnaires were verbally administered to a convenience sample of newly immigrated (acculturation, Latinos with lower levels of acculturation were more likely to use the PED to meet their children's health care needs. It seems that our PED has higher usage by Latino families compared with non-Latino families, which may be related to the lack of Latino-focused health infrastructure in our city. Once these families present to the PED, they do not seem to differ from overall users at our ED and nationally with regard to reason for visit. Similar to many other secondary migration hubs across the United States, our city has experienced dramatic growth in its Latino population in the last several years. Although health care providers anecdotally report increased service to Spanish-speaking populations, very little is known about the health care experience of Latino families in our area. To provide both equal and expert care to Latino children in the PED setting, it is essential that providers have this information specific to the context in which they work.

  1. Development of an integrated optical coherence tomography-gas nozzle system for surgical laser ablation applications: preliminary findings of in situ spinal cord deformation due to gas flow effects. (United States)

    Wong, Ronnie; Jivraj, Jamil; Vuong, Barry; Ramjist, Joel; Dinn, Nicole A; Sun, Cuiru; Huang, Yize; Smith, James A; Yang, Victor X D


    Gas assisted laser machining of materials is a common practice in the manufacturing industry. Advantages in using gas assistance include reducing the likelihood of flare-ups in flammable materials and clearing away ablated material in the cutting path. Current surgical procedures and research do not take advantage of this and in the case for resecting osseous tissue, gas assisted ablation can help minimize charring and clear away debris from the surgical site. In the context of neurosurgery, the objective is to cut through osseous tissue without damaging the underlying neural structures. Different inert gas flow rates used in laser machining could cause deformations in compliant materials. Complications may arise during surgical procedures if the dura and spinal cord are damaged by these deformations. We present preliminary spinal deformation findings for various gas flow rates by using optical coherence tomography to measure the depression depth at the site of gas delivery.

    ) and pre-exposure prophylaxis (PReP) (mean difference=0.658, P=.05). There were, however, no significant differences between Real Talk and control participants regarding actual condom use or other risk reduction strategies. Conclusions Our findings suggest that Real Talk supports engagement on HIV prevention issues. The lack of behavior findings may relate to insufficient study power or the fact that a 2-hour, standalone intervention may be insufficient to motivate behavioral change. In conclusion, we argue that Real Talk’s modular format facilitates its utilization within a broader array of prevention activities and may contribute to higher PReP utilization in black MSM communities.

    Purpose: To evaluate changes in high energy phosphate (HEP) metabolism in patients with hypertension and diastolic dysfunction but with normal LVEF > 55% assessed by echocardiography and tissue Doppler. Material and methods: 20 patients (16 men and 4 women, mean age 57 {+-} 13 years) were studied with phosphorus magnetic resonance spectroscopy and echocardiography. MRS was performed at 1.5 T using an ECG-gated CSI sequence with nuclear Overhauser effect. According to echocardiographical findings 12 patients were found to have a diastolic dysfunction, whereas 8 patients were identified as normal, serving as control group in the following statistical analysis. All patients had normal systolic function (LVEF > 55%).Statistical analysis was made by using mean {+-} S.D. for description of the data, Spearman correlation and two-tailed Student's t-test for independent samples. Results: No differences were found in weight, age, LVEF, endsystolic volume, end-diastolic volume, cardiac output and BNP levels between patients and control group. Myocardial mass at end-diastole correlated significantly with PCr/ATP ratio (r = -0.66; p = 0.04) in patients and control group. Myocardial PCr/ATP ratio in patients was significantly decreased compared to controls (1.21 {+-} 0.22 vs. 1.54 {+-} 0.24; p = 0.006). Conclusions: Cardiac {sup 31}P-MRS might offer a noninvasive means for detecting early states of heart failure in hypertensive patients.

  4. Potential Effects of Nichi Glucan as a Food Supplement for Diabetes Mellitus and Hyperlipidemia: Preliminary Findings from the Study on Three Patients from India

    Vidyasagar Devaprasad Dedeepiya


    Full Text Available Beta Glucan food supplements have been reported to be of benefit in diabetes and hyperlipidemia. We report a pilot study of the effects of Nichi Glucan, 1, 3-1, 6 Beta Glucan food supplement, in lowering the blood glucose and lipid levels in three patients with noninsulin-dependent diabetes mellitus (NIDDM from India. These patients had increased blood glucose and lipid levels inspite of routine antidiabetic and lipid level lowering medications. Each of the participants took 1.5 g of Nichi Glucan per day with food for two months along with their routine medications. The relevant parameters to assess glycemic status and lipid levels were calculated at the baseline and at the end of two months. After two months of continuous consumption, in one patient, the HbA1c decreased from 9.1% to 7.8%, and the glycemic target of HbA1c <6.5% laid down by the International Diabetes Federation was reached in two patients. Lipid levels also decreased significantly. Based on our findings, Nichi Glucan food supplement can be considered along with routine medications in patients with Type II diabetes with hyperlipidemia. Further studies are needed to validate the results.

  5. Identification of acoustically similar and dissimilar vowels in profoundly deaf adults who use hearing aids and/or cochlear implants: some preliminary findings. (United States)

    Hay-McCutcheon, Marcia J; Peterson, Nathaniel R; Rosado, Christian A; Pisoni, David B


    In this study, the authors examined the effects of aging and residual hearing on the identification of acoustically similar and dissimilar vowels in adults with postlingual deafness who use hearing aids (HAs) and/or cochlear implants (CIs). The authors used two groups of acoustically similar and dissimilar vowels to assess vowel identification. Also, the Consonant-Nucleus-Consonant Word Recognition Test (Peterson & Lehiste, 1962) and sentences from the Hearing in Noise Test (Nilsson, Soli, & Sullivan, 1994) were administered. Forty CI recipients with postlingual deafness (ages 31-81 years) participated in the study. Acoustically similar vowels were more difficult to identify than acoustically dissimilar vowels. With increasing age, performance deteriorated when identifying acoustically similar vowels. Vowel identification was also affected by the use of a contralateral HA and the degree of residual hearing prior to implantation. Moderate correlations were found between speech perception and vowel identification performance. Identification performance was affected by the acoustic similarity of the vowels. Older adults experienced more difficulty identifying acoustically similar confusable vowels than did younger adults. The findings might lend support to the ease of language understanding model (Ronnberg, Rudner, Foo, & Lunner, 2008), which proposes that the quality and perceptual robustness of acoustic input affects speech perception.

  6. Exploring classical conditioning for strengthening the links between semantic and lexical representations in pure anomia: Preliminary findings from a single case study. (United States)

    Zannino, Gian Daniele; Barban, Francesco; Caltagirone, Carlo; Carlesimo, Giovanni A


    The same language symptom might arise at different functional loci in people with aphasia. Therefore, it is plausible that different therapeutic interventions should be adopted to approach the same difficulties in different patients. Although this point of view is still widely accepted, recently the focus has shifted from the functional locus of a rehabilitative intervention to the mechanisms of action underlying the relearning process. We maintain that both aspects should be taken into account when programming a rehabilitative intervention; furthermore, investigating relearning mechanisms might shed new light on the functional architecture of the disrupted processes. Here, we investigated, in a single case study, whether classical conditioning was a suitable relearning paradigm for targeting word-finding difficulties in pure anomia, that is in a patient with an impairment in accessing intact output lexical representations from a spared semantic system. Using a word-repetition task on picture presentation, we contrasted a condition in which the stimulus onset asynchrony between word and picture stimuli was well suited to produce classical conditioning with a condition in which repetition training could not benefit from this learning mechanism. Only classical conditioning training exerted a significant, long-lasting effect on our patient's naming skill. Tentative implications of our results for the functional architecture of single-word processing are discussed. © 2015 The British Psychological Society.

  7. Psychoeducational intervention focused on healthy living improves psychopathological severity and lifestyle quality in psychiatric patients: preliminary findings from a controlled study. (United States)

    Individuals with psychiatric disorders incur an increased risk of morbidity and mortality, with higher prevalence of cardio-metabolic risk factors s largely contributing to a significant reduction in life expectancy. The aim of the present study was at evaluating the clinical effectiveness of an educational intervention targeting lifestyle habits in patients with mood and psychotic disorders. Patients (n = 32) were randomly assigned to receive, in addition to the pharmacological treatment, either five sessions of group psychoeducation focused on healthy lifestyle or five sessions of a control group therapy. Both psychopathological severity (i.e. the brief psychiatric rating scale) and lifestyle quality (i.e. physical activity, sleep quality and adherence to the Mediterranean diet) improved significantly over time in patients who underwent specific psychoeducational sessions but not in the controls. These findings add to the accumulating evidence that educational interventions focused on lifestyle habits can ameliorate general and mental health in patients with psychiatric disorders and suggest that educational programs represent an effective non-pharmacological intervention to manage drug-induced cardiometabolic disturbances.

  8. n-back task performance and corresponding brain-activation patterns in women with restrictive and bulimic eating-disorder variants: preliminary findings. (United States)

    Israel, Mimi; Klein, Michael; Pruessner, Jens; Thaler, Lea; Spilka, Michael; Efanov, Simona; Ouellette, Anne-Sophie; Berlim, Marcelo; Ali, Nida; Beaudry, Thomas; Van den Eynde, Frederique; Walker, Claire-Dominique; Steiger, Howard


    Eating disorder (ED) variants characterized by "binge-eating/purging" symptoms differ from "restricting-only" variants along diverse clinical dimensions, but few studies have compared people with these different eating-disorder phenotypes on measures of neurocognitive function and brain activation. We tested the performances of 19 women with "restricting-only" eating syndromes and 27 with "binge-eating/purging" variants on a modified n-back task, and used functional magnetic resonance imaging (fMRI) to examine task-induced brain activations in frontal regions of interest. When compared with "binge-eating/purging" participants, "restricting-only" participants showed superior performance. Furthermore, in an intermediate-demand condition, "binge-eating/purging" participants showed significantly less event-related activation than did "restricting-only" participants in a right posterior prefrontal region spanning Brodmann areas 6-8-a region that has been linked to planning of motor responses, working memory for sequential information, and management of uncertainty. Our findings suggest that working memory is poorer in eating-disordered individuals with binge-eating/purging behaviors than in those who solely restrict food intake, and that observed performance differences coincide with interpretable group-based activation differences in a frontal region thought to subserve planning and decision making.

  9. The effectiveness of a group-based acceptance and commitment additive therapy on rehabilitation of female outpatients with chronic headache: preliminary findings reducing 3 dimensions of headache impact. (United States)

    Mo'tamedi, Hadi; Rezaiemaram, Payman; Tavallaie, Abaas


    Examine whether acceptance and commitment additive therapy is effective in reducing the experience of sensory pain, disability, and affective distress because of chronic headache in a sample of outpatient Iranian females. Chronic headaches have a striking impact on sufferers in terms of pain, disability, and affective distress. Although several Acceptance and Commitment Therapy outcome studies for chronic pain have been conducted, their findings cannot be completely generalized to chronic headaches because headache-related treatment outcome studies have a different emphasis in both provision and outcomes. Moreover, the possible role of Iranian social and cultural contexts and of gender-consistent issues involved in Acceptance and Commitment Therapy outcomes deserve consideration. This study used a randomized pretest-post-test control group design. The sample was selected from consecutive female outpatients with chronic headache, attending and/or referred to a headache clinic in a governmental hospital from April 2011 to June 2011. In total, 80 female outpatients were interviewed, and after implementing inclusion/exclusion criteria, thirty females were considered eligible to participate in the study. Half (n = 15) were randomly selected to participate in the treatment group. Four participants of this group failed to complete the treatment sessions (n = 11). The Acceptance and Commitment Therapy group received the medical treatment as usual and 8 sessions of Acceptance and Commitment Therapy. The other half (n = 15) served as the control group that received only medical treatment as usual. The short form of McGill pain questionnaire, the migraine disability assessment scale, and the trait subscale of the state-trait anxiety inventory were administered, which operationalized 3 dimensions of impact of chronic headache, sensory pain, disability, and emotional distress, respectively, to explore the impact of recurrent headache episodes.

  11. PCSK9 variation and association with blood pressure in African Americans: preliminary findings from the HyperGEN and REGARDS studies

    Directory of Open Access Journals (Sweden)

    Ngan T Tran


    Full Text Available Proprotein convertase subtilisin/kexin type 9 (encoded by PCSK9 plays a well-known role in the regulation of low-density lipoprotein (LDL receptors, and an inhibitor of this enzyme is a promising new therapeutic for hyperlipidemia. Recently, animal and human studies also implicate PCSK9 genetic variation in the regulation of blood pressure. The goal of this study was to examine if common and rare polymorphisms in PCSK9 are associated with blood pressure in an African-American population at high risk for cardiovascular disease. Using genomic data assayed on the Affymetrix 6.0 array (n = 1199 and the Illumina HumanExome Beadchip (n = 1966 from the Hypertension Genetic Epidemiology Network (HyperGEN, we tested the association of PCSK9 polymorphisms with blood pressure. We used linear mixed models and the sequence kernel association test (SKAT to assess the association of 31 common and 19 rare variants with blood pressure. The models were adjusted for age, sex, center, smoking status, principal components for ancestry and diabetes as fixed effects and family as a random effect. The results showed a marginally significant effect of two genome-wide association study (GWAS single-nucleotide polymorphisms (SNPs (rs12048828: β = 1.8, P = 0.05 and rs9730100: β = 1.0, P = 0.05 with diastolic blood pressure (DBP; however these results were not significant after correction for multiple testing. Rare variants were cumulatively associated with DBP (P = 0.04, an effect that was strengthened by restriction to nonsynonymous or stop-gain SNPs (P = 0.02. While gene-based results for DBP did not replicate (P = 0.36, we found an association with SBP (P = 0.04 in the Reasons for Geographic And Racial Differences in Stroke study (REGARDS. The findings here suggest rare variants in PCSK9 may influence blood pressure among African Americans, laying the ground work for further validation studies.

  12. Hearing screening outcomes for persons with intellectual disability: a preliminary report of findings from the 2005 Special Olympics World Winter Games. (United States)

    Kumar Sinha, Ashok; Montgomery, Judy K; Herer, Gilbert R; McPherson, David L


    The Special Olympics Healthy Hearing Program provides a unique opportunity to determine the hearing service needs of individuals with mild intellectual disabilities participating in athletic endeavors in countries throughout the world. The Healthy Hearing Program screened 855 of 1800 athletes with intellectual disability over a period of a week at Nagano, Japan. Of 855 athletes screened, 58% passed the DPOAE screen and therefore required no further testing. Of the remaining 42%, 186 did not pass pure-tone screening. This number of athletes represents 21.8% of all athletes screened. Tympanometry outcomes for the 186 athletes failing pure-tone screening showed 56% (104) also failing this measure of middle-ear function. 65% of these 104 athletes' outer ear canals were blocked/partially-blocked with cerumen. This amount is in contrast to the 38% presence of cerumen for the 82 athletes failing pure-tone screening but passing tympanometry.

    Yoshimura, Yasuro; Oka, Masafumi; Harada, Toshio; Sugihara, Takahide; Kishimoto, Hirofumi; Matsuura, Ryozi; Santho, Eri; Tanaka, Masahiko; Matsumoto, Ken


    This clinical study presents 15 patients with lesions of the major salivary glands and surrounding tissues, and describes the importance of imaging diagnosis of their diseases. The availability of imaging diagnosis was intended to, 1) demonstrate the pathological conditions as either an extrinsic or an intrinsic lesion of the salivary gland, 2) depict the important structures such as facial nerve, and blood vessels, and to clarify the relationship between them and the lesion, 3) provide a clearer grasp of the extent of the lesion, especially when the lesion is a tumor, 4) help to discriminate between inflammation from a tumor which is malignant and from a lesion which is benign, 5) facilitate discussion and detection of metastases in the regional lymph nodes and remote organs, 6) help with early and precise detection of recurrence after primary treatment and/or in the follow-up period.

  14. The UP-TECH project, an intervention to support caregivers of Alzheimer's disease patients in Italy: preliminary findings on recruitment and caregiving burden in the baseline population. (United States)

    Chiatti, Carlos; Rimland, Joseph M; Bonfranceschi, Franco; Masera, Filippo; Bustacchini, Silvia; Cassetta, Laura


    The paper describes recruitment results and characteristics of the UP-TECH clinical trial sample, including level of care services use, informal caregiver burden and its determinants. UP-TECH is designed to test innovative care solutions for community-dwelling patients with moderate stage Alzheimer's disease and their caregivers in Italy. Four hundred and fifty patient-caregiver dyads were randomized into three arms receiving different combinations of services, composed of case management interventions, nurse visits, assistive technology and educational brochures. The research nurses administered a questionnaire comprising an in-depth socio-demographic assessment and several clinical scales, such as Novak's Caregiver Burden Inventory. Analyses of baseline data were conducted using uni- and bi-variate statistics. Linear regressions were computed to identify de-confounded correlates of caregiver burden. Four hundred and thirty-eight patient-caregiver dyads were recruited and randomized. In our sample, patients are predominantly women (71.5%), with an average age of 81.5 years and a mean Mini-Mental State Examination score of 16.2. Caregivers are mostly women (66.2%) and offspring (55.7%), with a mean caregiver burden score of 27.6. They provide more than 50 hours of care per week, while receiving an almost negligible support from public services. Factors associated with caregiver burden are female gender, kinship and the patient's behavioral disturbances. The most important factor associated with lower burden is the employment of a live-in care worker. The paper provides a comprehensive description of moderate stage Alzheimer's disease patients and their caregivers, suggesting useful markers of caregiver burden. The well-balanced randomization assures the reliability of the study data-set for prospective evaluation of care strategies.

  15. State- or trait-like individual differences in dream recall: Preliminary findings from a within-subjects study of multiple nap REM sleep awakenings

    Directory of Open Access Journals (Sweden)

    Serena eScarpelli


    Full Text Available We examined the question whether the role of EEG oscillations in predicting presence/absence of dream recall (DR is explained by state- or trait-like factors. Six healthy subjects were awakened from REM sleep in a within-subjects design with multiple naps, until a recall (REC and a non-recall (NREC condition were obtained. Naps were scheduled in the early afternoon and were separated by one week. Topographical EEG data of the 5-min of REM sleep preceding each awakening were analyzed by power spectral analysis [Fast Fourier Transform (FFT] and by a method to detect oscillatory activity [Better OSCillations (BOSC].Both analyses show that REC is associated to higher frontal theta activity (5-7 Hz and theta oscillations (6.06 Hz compared to NREC condition, but only the second comparison reached significance. Our pilot study provides support to the notion that sleep and wakefulness share similar EEG correlates of encoding in episodic memories, and supports the state-like hypothesis: dream recall may depend on the physiological state related to the sleep stage from which the subject is awakened rather than on a stable individual EEG pattern.

  17. Polish Migration’s Socio-Cultural Impact on Wales in the Aftermath of 2004 – Preliminary Findings from Western Wales: An Aberystwyth Case Study

    Directory of Open Access Journals (Sweden)

    Wróbel Paweł


    Full Text Available This papers looks at the societal and cultural impact of the post-2004 Polish migration to Wales. The history of Polish migration to the UK is introduced together with the relevant statistics and their rationale behind choosing cosmopolitan Wales as their new country of residence. Even though the focus of the paper is rather on the UK as a whole, it is Wales that is central to the investigation. Wales was particularly neglected in the study of migration in the aftermath of the 2004 European Union (EU enlargement and surprisingly little attention was given to it. Focusing on Polish diaspora is important as it is the most numerous external migration wave to Wales (ONS 2011. The case study of Aberystwyth is introduced as a good example of a semi-urban area to which Poles migrated after 2004. Moreover, the paper elaborates on the characteristics of the Polish newcomers by analysing their distinctive features, migration patterns as well as adaptation processes. Mutual relations between post-1945 and post-2004 immigration waves are investigated, together with Poles’ own image and perception. This paper gives a deeper understanding and provides an insight into the nature of the Polish migrants’ impact on the cultural and societal life of Wales.

    Sanjay Dixit


    Full Text Available Introduction: Evaluating the needs of People Living with HIV / AIDS (PLHA and providing them with adequate care and support is important in combating the Acquired Immunodeficiency Syndrome (AIDS epidemic. Objectives: The study was conducted to ascertain the needs of PLHA, the support obtained and required, extent of involvement in programs related to HIV and evaluate the impact of Government programs as perceived by PLHA. Methods: A cross sectional study was conducted on 150 PLHA in the districts of Indore, Neemuch and Ujjain in the state of Madhya Pradesh (India using semi-structured interview schedules. The data was analyzed using SPSS version 12.0. Results: The major support available to the patients is the free Anti-Retroviral Therapy (ART available at Government health care centers. The other supports obtained from self help groups and NGOs were medicines for opportunistic infections, nutritional supplements, traveling allowance to ART center for monthly doses, free monthly ration and school fees for one child in the family. The major support required were an educational plan for children, free investigations at hospitals, decentralization of ART centers and adequate employment opportunities. Involvement of PLHA in health programs was minimal: the reasons for non-involvement being unwillingness, fear of disclosure and lack of opportunity. The respondents stated that Government policies have had a positive impact and changed the perception of the society towards HIV patients. Conclusion: PLHA have a number of unmet needs and a collaborative attempt from the government and support groups is needed to meet the needs of PLHA

    Full Text Available This article presents results of ongoing research into personal networks in São Paulo, exploring their relationships with poverty and urban segregation. We present the results of networks of 89 poor individuals who live in three different segregation situations in the city. The article stats by describing and analyzing the main characteristics of personal networks of sociability, highlighting aspects such as their size, cohesion and diversity, among others. Furgher, we investigate the main determinants of these networks, especially their relationship with urban segregation, understood as separation between social groups in the city, and specific forms of sociability. Contrary to much of the literature which takes into account only segregation of individual attributes in the urban space (race, ethnicity, socioeconomic level etc., this investigation tests the importance both of networks and segregation in the reproduction of poverty situations.

  2. Experimental interstellar organic chemistry: Preliminary findings (United States)

    Khare, B. N.; Sagan, C.


    In a simulation of interstellar organic chemistry in dense interstellar clouds or on grain surfaces, formaldehyde, water vapor, ammonia and ethane are deposited on a quartz cold finger and ultraviolet-irradiated in high vacuum at 77K. The HCHO photolytic pathway which produces an aldehyde radical and a superthermal hydrogen atom initiates solid phase chain reactions leading to a range of new compounds, including methanol, ethanol, acetaldehyde, acetonitrile, acetone, methyl formate, and possibly formic acid. Higher nitriles are anticipated. Genetic relations among these interstellar organic molecules (e.g., the Cannizzaro and Tischenko reactions) must exist. Some of them, rather than being synthesized from smaller molecules, may be degradation products of larger organic molecules, such as hexamethylene tetramine, which are candidate consitituents of the interstellar grains. The experiments reported here may also be relevant to cometary chemistry.

  7. An Investigation of the Academic Information Finding and Re-finding Behavior on the Web

    Directory of Open Access Journals (Sweden)

    Hsiao-Tieh Pu


    Full Text Available Academic researchers often need and re-use relevant information found after a period of time. This preliminary study used various methods, including experiments, interviews, search log analysis, sequential analysis, and observation to investigate characteristics of academic information finding and re-finding behavior. Overall, the participants in this study entered short queries either in finding or re-finding phases. Comparatively speaking, the participants entered greater number of queries, modified more queries, browsed more web pages, and stayed longer on web pages in the finding phase. On the other hand, in the re-finding phase, they utilized personal information management tools to re-find instead of finding again using search engine, such as checking browsing history; moreover, they tend to input less number of queries and stayed shorter on web pages. In short, the participants interacted more with the retrieval system during the finding phase, while they increased the use of personal information management tools in the re-finding phase. As to the contextual clues used in re-finding phase, the participants used less clues from the target itself, instead, they used indirect clues more often, especially location-related information. Based on the results of sequential analysis, the transition states in the re-finding phase was found to be more complex than those in the finding phase. Web information finding and re-finding behavior is an important and novel area of research. The preliminary results would benefit research on Web information re-finding behavior, and provide useful suggestions for developing personal academic information management systems.

    Reed, W.R.


    The Old Hydrofracture Facility (OHF) is one of approximately 76 facilities currently managed by the Oak Ridge National Laboratory (ORNL) Surplus Facilities Management Program (SFMP). This program, as part of the Department of Energy (DOE) national SFMP, is responsible for the maintenance and surveillance and the final decommissioning of radioactively contaminated surplus ORNL facilities. A long-range planning effort is being conducted that will outline the scope and objectives of the ORNL program and establish decommissioning priorities based on health and safety concerns, budget constraints, and other progammatic constraints. IN support of this SFMP planning activity, preliminary engineering assessments are being conducted for each of the ORNL surplus facilities currently managed under the program. These efforts are designed to: (1) provide an initial assessment of the potential decommissioning alternatives, (2) choose a preferred alternative and provide a justification for that choice, and (3) provide a preliminary description of the decommissioning plan, including cost and schedule estimates. This report presents the results of the preliminary analysis for the OHF.

    Godfather Dickson Kimaro

    Full Text Available Understanding the costs associated with health care delivery strategies is essential for planning. There are few data on health service resources used by patients and their associated costs within antiretroviral (ART programmes in Africa.The study was nested within a large trial, which evaluated screening for cryptococcal meningitis and tuberculosis and a short initial period of home-based adherence support for patients initiating ART with advanced HIV disease in Tanzania and Zambia. The economic evaluation was done in Tanzania alone. We estimated costs of providing routine ART services from the health service provider's perspective using a micro-costing approach. Incremental costs for the different novel components of service delivery were also estimated. All costs were converted into US dollars (US$ and based on 2012 prices.Of 870 individuals enrolled in Tanzania, 434 were enrolled in the intervention arm and 436 in the standard care/control arm. Overall, the median (IQR age and CD4 cell count at enrolment were 38 [31, 44] years and 52 [20, 89] cells/mm3, respectively. The mean per patient costs over the first three months and over a one year period of follow up following ART initiation in the standard care arm were US$ 107 (95%CI 101-112 and US$ 265 (95%CI 254-275 respectively. ART drugs, clinic visits and hospital admission constituted 50%, 19%, and 19% of the total cost per patient year, while diagnostic tests and non-ART drugs (co-trimoxazole accounted for 10% and 2% of total per patient year costs. The incremental costs of the intervention to the health service over the first three months was US$ 59 (p<0.001; 95%CI 52-67 and over a one year period was US$ 67(p<0.001; 95%CI 50-83. This is equivalent to an increase of 55% (95%CI 51%-59% in the mean cost of care over the first three months, and 25% (95%CI 20%-30% increase over one year of follow up.

  20. Granulomatous mastitis: radiological findings

    Energy Technology Data Exchange (ETDEWEB)

    Ozturk, M.; Mavili, E.; Kahriman, G.; Akcan, A.C.; Ozturk, F. [Depts. of Radiology, Surgery, and Pathology, Erciyes Univ. Medical Faculty, Kayseri (Turkey)


    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

  1. Post-operative 3-dimensional contrast-enhanced ultrasound (CEUS) versus Tc99m-DTPA in the detection of post-surgical perfusion defects in kidney transplants - preliminary findings. (United States)

    Stenberg, B; Chandler, C; Wyrley-Birch, H; Elliott, S T


    2800 renal transplants are carried out annually in the UK and it is standard practice to perform a Tc-DTPA renogram examination after surgery to check perfusion. This provides some functional information but suffers from low spatial resolution, is lengthy, immobile and costly and uses ionizing radiation. We surmised that contrast-enhanced ultrasound (CEUS) would provide an accurate alternative with increased speed, resolution (temporal and spatial), cost efficiency and safety. 97 renal transplant patients underwent both Tc-DTPA and CEUS after surgery to assess the perfusion of the graft. Tc-DTPA was performed in the nuclear medicine department with at least 10 minutes of continuous screening and a standard dose of 150 mBq Tc-DTPA. CEUS consisted of I. V. 2.4 ml Sonovue contrast agent, 60 seconds continuous capture and a 3 D acquisition of the organ. 3 D CEUS was assessed using QLab analysis software. Tc-DTPA detected 9 perfusion defects of varying size. CEUS detected all these defects plus 14 further defects (0.2 - 17 % of total renal volume) not detected on DTPA. These results demonstrate a statistically significant divergence (p polar arteries in 8 of these 14 cases. CEUS will detect perfusion defects seen with Tc-DTPA and due to increased spatial and temporal resolution and multiple scanning angles, will detect further perfusion defects not seen on Tc-DTPA. 3 D CEUS is useful in the quantification of perfusion defects. CEUS is an accurate examination for detecting renal transplant perfusion defects and will detect significantly more defects than DTPA. © Georg Thieme Verlag KG Stuttgart · New York.

  2. Cognitive Task Analysis of Business Jet Pilots' Weather Flying Behaviors: Preliminary Results (United States)

    Latorella, Kara; Pliske, Rebecca; Hutton, Robert; Chrenka, Jason


    This report presents preliminary findings from a cognitive task analysis (CTA) of business aviation piloting. Results describe challenging weather-related aviation decisions and the information and cues used to support these decisions. Further, these results demonstrate the role of expertise in business aviation decision-making in weather flying, and how weather information is acquired and assessed for reliability. The challenging weather scenarios and novice errors identified in the results provide the basis for experimental scenarios and dependent measures to be used in future flight simulation evaluations of candidate aviation weather information systems. Finally, we analyzed these preliminary results to recommend design and training interventions to improve business aviation decision-making with weather information. The primary objective of this report is to present these preliminary findings and to document the extended CTA methodology used to elicit and represent expert business aviator decision-making with weather information. These preliminary findings will be augmented with results from additional subjects using this methodology. A summary of the complete results, absent the detailed treatment of methodology provided in this report, will be documented in a separate publication.

    Chung, Sangkeun; Kim, Sun S; Kini, Nisha; Fang, Hua J; Kalman, David; Ziedonis, Douglas M


    This is the first study of Korean Americans' smoking behavior using a topography device. Korean American men smoke at higher rates than the general U.S. Korean American and White men were compared based on standard tobacco assessment and smoking topography measures. They smoked their preferred brand of cigarettes ad libitum with a portable smoking topography device for 24 h. Compared to White men (N = 26), Korean American men (N = 27) were more likely to smoke low nicotine-yield cigarettes (p Koreans smoked fewer cigarettes with the device (p = 0.01) than Whites. Controlling for the number of cigarettes smoked, Koreans smoked with higher average puff flows (p = 0.05), greater peak puff flows (p = 0.02), and shorter interpuff intervals (p smoking patterns among Korean American men who are likely to smoke low nicotine-yield cigarettes. We found that Korean American men compensated their lower number and low nicotine-yield cigarettes by smoking with greater puff flows and shorter interpuff intervals than White men, which may suggest exposures to similar amounts of nicotine and harmful tobacco toxins by both groups. Clinicians will need to consider in identifying and treating smokers in a mutually aggressive manner, irrespective of cigarette type and number of cigarette smoked per day.

  10. Periodontitis and nosocomial lower respiratory tract infection: preliminary findings. (United States)

    Gomes-Filho, Isaac Suzart; Santos, Carla M L; Cruz, Simone S; Passos, Johelle de S; Cerqueira, Eneida de M M; Costa, Maria da Conceição N; Santana, Teresinha C; Seymour, Gregory J; Santos, Carlos Antonio de S T; Barreto, Maurício L


    To evaluate the possible association between periodontitis and nosocomial lower respiratory tract infection (LRTI). A case-control study was conducted at a General Hospital in Feira de Santana, Bahia, Brazil. The sample consisted of 103 individuals: 22 cases (presence of nosocomial LRTI) and 81 controls (absence of nosocomial LRTI). The diagnosis of periodontitis was based on probing depth, gingival recession, clinical attachment loss and bleeding on probing. The diagnosis of nosocomial LRTI was made in accordance with established medical criteria. Invasive ventilation was much more frequent in cases (95.5%) than in controls (7.4%). An orotracheal tube was used in 81.8% of cases and in 7.4% of controls; bronchoaspiration was suspected in 81.8% of cases and in 6.2% of controls. There was no statistically significant difference in any of the clinical periodontal parameters between cases and controls. The crude odds ratio (OR) value for individuals with periodontitis having LRTI was not statistically significant [OR(crude)=1.70; 95% confidence interval:(0.60-4.87)]. After including age, smoking and duration of hospitalization in the logistic regression, the adjusted OR for individuals with periodontitis having LRTI was statistically significant [OR(adjusted)=3.67 (1.01-13.53); p=0.049]. A marginal association between periodontitis and LRTI was found when smoking, age and length of hospitalization were included as covariates. Patients with LRTI had a high frequency of suspected bronchoaspiration and this could explain the possible association of periodontal disease and LRTI found in this and other studies. Additional studies are needed to further clarify the possible relationship between periodontal disease and LRTI.

  15. Narcissism and consumer behaviour: a review and preliminary findings


    Cisek, Sylwia Z.; Constantine eSedikides; Hart, Claire M.; Godwin, Hayward J.; Valerie eBenson; Liversedge, Simon P.


    We review the literature on the relation between narcissism and consumer behaviour. Consumer behaviour is sometimes guided by self-related motives (e.g., self-enhancement) rather than by rational economic considerations. Narcissism is a case in point. This personality trait reflects a self-centred, self-aggrandizing, dominant, and manipulative orientation. Narcissists are characterised by exhibitionism and vanity, and they see themselves as superior and entitled. To validate their grand...

  17. Smart Ultrasound Remote Guidance Experiment (SURGE) Preliminary Findings (United States)

    Hurst, Victor; Dulchavsky, Scott; Garcia, Kathleen; Sargsyan, Ashot; Ebert, Doug


    To date, diagnostic quality ultrasound images were obtained aboard the International Space Station (ISS) using the ultrasound of the Human Research Facility (HRF) rack in the Laboratory module. Through the Advanced Diagnostic Ultrasound in Microgravity (ADUM) and the Braslet-M Occlusion Cuffs (BRASLET SDTO) studies, non-expert ultrasound operators aboard the ISS have performed cardiac, thoracic, abdominal, vascular, ocular, and musculoskeletal ultrasound assessments using remote guidance from ground-based ultrasound experts. With exploration class missions to the lunar and Martian surfaces on the horizon, crew medical officers will necessarily need to operate with greater autonomy given communication delays (round trip times of up to 5 seconds for the Moon and 90 minutes for Mars) and longer periods of communication blackouts (due to orbital constraints of communication assets). The SURGE project explored the feasibility and training requirements of having non-expert ultrasound operators perform autonomous ultrasound assessments in a simulated exploration mission outpost. The project aimed to identify experience, training, and human factors requirements for crew medical officers to perform autonomous ultrasonography. All of these aims pertained to the following risks from the NASA Bioastronautics Road Map: 1) Risk 18: Major Illness and Trauna; 2) Risk 20) Ambulatory Care; 3) Risk 22: Medical Informatics, Technologies, and Support Systems; and 4) Risk 23: Medical Skill Training and Maintenance.

  2. Preliminary Geological Findings on the BP-1 Simulant (United States)

    Stoeser, D. B.; Rickman, D. L.; Wilson, S.


    A waste material from an aggregate producing quarry has been used to make an inexpensive lunar simulant called BP-1. The feedstock is the Black Point lava flow in northern Arizona. Although this is part of the San Francisco volcanic field, which is also the source of the JSC-1 series feedstock, BP-1 and JSC-1 are distinct. Chemically, the Black Point flow is an amygdaloidal nepheline-bearing basalt. The amygdules are filled with secondary minerals containing opaline silica, calcium carbonate, and ferric iron minerals. X-ray diffraction (XRD) detected approximately 3% quartz, which is in line with tests done by the Kennedy Space Center Industrial Hygiene Office. Users of this material should use appropriate protective equipment. XRD also showed the presence of significant halite and some bassanite. Both are interpreted to be evaporative residues due to recycling of wash water at the quarry. The size distribution of BP-1 may be superior to some other simulants for some applications.

  3. Utility of Social Modeling for Proliferation Assessment - Preliminary Assessment

    Energy Technology Data Exchange (ETDEWEB)

    Coles, Garill A.; Gastelum, Zoe N.; Brothers, Alan J.; Thompson, Sandra E.


    This Preliminary Assessment draft report will present the results of a literature search and preliminary assessment of the body of research, analysis methods, models and data deemed to be relevant to the Utility of Social Modeling for Proliferation Assessment research. This report will provide: 1) a description of the problem space and the kinds of information pertinent to the problem space, 2) a discussion of key relevant or representative literature, 3) a discussion of models and modeling approaches judged to be potentially useful to the research, and 4) the next steps of this research that will be pursued based on this preliminary assessment. This draft report represents a technical deliverable for the NA-22 Simulations, Algorithms, and Modeling (SAM) program. Specifically this draft report is the Task 1 deliverable for project PL09-UtilSocial-PD06, Utility of Social Modeling for Proliferation Assessment. This project investigates non-traditional use of social and cultural information to improve nuclear proliferation assessment, including nonproliferation assessment, proliferation resistance assessments, safeguards assessments and other related studies. These assessments often use and create technical information about the State’s posture towards proliferation, the vulnerability of a nuclear energy system to an undesired event, and the effectiveness of safeguards. This project will find and fuse social and technical information by explicitly considering the role of cultural, social and behavioral factors relevant to proliferation. The aim of this research is to describe and demonstrate if and how social science modeling has utility in proliferation assessment.

  4. Preliminary Analysis of Photoreading (United States)

    McNamara, Danielle S.


    The purpose of this project was to provide a preliminary analysis of a reading strategy called PhotoReading. PhotoReading is a technique developed by Paul Scheele that claims to increase reading rate to 25,000 words per minute (Scheele, 1993). PhotoReading itself involves entering a "relaxed state" and looking at, but not reading, each page of a text for a brief moment (about I to 2 seconds). While this technique has received attention in the popular press, there had been no objective examinations of the technique's validity. To examine the effectiveness of PhotoReading, the principal investigator (i.e., trainee) participated in a PhotoReading workshop to learn the technique. Parallel versions of two standardized and three experimenter-created reading comprehension tests were administered to the trainee and an expert user of the PhotoReading technique to compare the use of normal reading strategies and the PhotoReading technique by both readers. The results for all measures yielded no benefits of using the PhotoReading technique. The extremely rapid reading rates claimed by PhotoReaders were not observed; indeed, the reading rates were generally comparable to those for normal reading. Moreover, the PhotoReading expert generally showed an increase in reading time when using the PhotoReading technique in comparison to when using normal reading strategies to process text. This increase in reading time when PhotoReading was accompanied by a decrease in text comprehension.

  8. Corporate Social Disclosures in Southeast Asia: A Preliminary Study

    Directory of Open Access Journals (Sweden)

    Juniati Gunawan


    Full Text Available The issue of Corporate Social Disclosure (CSD has been growing remarkably both in business and academic world.  Inevitably, this topic is also exposed in Southeast Asia, a big region that plays important role in global economic issue. Applying a content analysis method, this paper aims to provide preliminary findings in CSD practices throughout the companies‟ annual reports in 2007 and 2008 for countries located in Southeast Asia.  Samples were selected for listed and unlisted various type of industries, based on the information availability internet searching. The sample collection and the subjectivity during the content analysis process are the limitations in conducting this study. In general, the results show that „human resources‟ are the main information disclosed, while in contrast, „energy‟ is the main least issue disclosed in the annual reports.  However, the findings need to be interpreted with considerations since there are limited in samples. Basically, the outcomes support the major prior studies and enhancing the discussion of CSD conducting in developing countries, while at the same time describing some countries which obtained very limited in exposures. To respond the vast increasing issues of CSD practice, this preliminary study has provided a basis to see the role of every country in CSR reporting and how they could support the sustainability development globally.

  9. Postpartum contraception: perspectives from clients and providers in six countries. (United States)

    Rabinovitz, L M; Landry, E


    This article presents preliminary findings of a study conducted by the Association for Voluntary Surgical Contraception (AVSC) designed to investigate women's interest in postpartum contraception and the preferred timing for getting information. A pioneering study, AVSC's research took place in Colombia, the Dominican Republic, India, Kenya, Mali, and Turkey. In each countries, AVSC conducted 4-6 focus groups with pregnant women, interviews with 100 postpartum women, and interviews with 30 service providers. While a final report is due out in January, AVSC has established some preliminary findings. Except in Turkey, more than 1/2 the postpartum women said that they would have been interested in receiving family planning information before and during pregnancy. In nearly all the countries, the unmet need for information was great. Only in Mali and Kenya, where AVSC introduced postpartum IUD projects last year, was there less of an unmet need. While 40% of Kenyan women leaving the hospital after delivery had adopted a contraceptive method, only 3% and 2% of the women in the Dominican Republic and Turkey, respectively, were leaving the hospital with a method. The overwhelming majority women thought that family planning should be provided prior to pregnancy or during prenatal care. Focus group discussions revealed that virtually all women thought that during labor was a bad time to get information, and that information could be given during postpartum visits or before a woman leaves the hospital after delivery. Responses by service providers were similar to those of women, except that most thought it would be appropriate to discuss family planning during labor. AVSC will use the findings of this study to design informational materials for postpartum contraception programs.

  10. Preliminary bolted-joint data (United States)

    Wichorek, G. R.


    Bolted-joint strength and failure modes for advanced graphite/polyimide composite laminates at 116K (-250 F), room temperature, and 589K (600 F) were determined to provide preliminary design data. The bolted-joint test setup for the low and elevated temperature tests is described. Test results are reported on a quasi-isotropic laminate of Celion 6000/PMR-15. Single bolt, double lap shear specimens were tested to obtain maximum joint strength and failure mode. The effect of joint geometry and temperature on joint strength and failure mode is presented.

  11. Internet Medline providers. (United States)

    Vine, D L; Coady, T R


    Each database in this review has features that will appeal to some users. Each provides a credible interface to information available within the Medline database. The major differences are pricing and interface design. In this context, features that cost more and might seem trivial to the occasional searcher may actually save time and money when used by the professional. Internet Grateful Med is free, but Ms. Coady and I agree the availability of only three ANDable search fields is a major functional limitation. PubMed is also free but much more powerful. The command line interface that permits very sophisticated searches requires a commitment that casual users will find intimidating. Ms. Coady did not believe the feedback currently provided during a search was sufficient for sustained professional use. Paper Chase and Knowledge Finder are mature, modestly priced Medline search services. Paper Chase provides a menu-driven interface that is very easy to use, yet permits the user to search virtually all of Medline's data fields. Knowledge Finder emphasizes the use of natural language queries but fully supports more traditional search strategies. The impact of the tradeoff between fuzzy and Boolean strategies offered by Knowledge Finder is unclear and beyond the scope of this review. Additional software must be downloaded to use all of Knowledge Finders' features. Other providers required no software beyond the basic Internet browser, and this requirement prevented Ms. Coady from evaluating Knowledge Finder. Ovid and Silver Platter offer well-designed interfaces that simplify the construction of complex queries. These are clearly services designed for professional users. While pricing eliminates these for casual use, it should be emphasized that Medline citation access is only a portion of the service provided by these high-end vendors. Finally, we should comment that each of the vendors and government-sponsored services provided prompt and useful feedback to e

  12. Preliminary results of UCN τ (United States)

    Pattie, Robert; UCNtau Collaboration


    There is currently a 4 σ discrepancy between measurements of the neutron lifetime performed using cold neutron beams and those performed with ultracold neutron (UCN) storage vessels. The UCN τ experiment uses an asymmetric magneto-gravitational UCN trap with in situ counting of surviving neutrons to measure the neutron lifetime. This design eliminates a major systematic of previous bottle experiments related to the loss of UCN on material trap walls and with unloading neutrons from the storage vessel. A new in situ detection system was used in the 2015-2016 run that was able to measure the population of surviving UCN at different heights in the trap, providing important information on spectral evolution. Understanding the behavior of quasi-bound UCN in a bottle experiment is essential to achieving a subsecond precision measurement of τn. We will present the preliminary results from the 2015-2016 data set and an update on the UCN τ experiment.

  14. [Incidental finding of proteinuria]. (United States)

    Galle, J


    A positive signal when testing urine for proteinuria is a frequent finding, either in the context of a routine medical check-up or when searching for a specific renal disorder. This brief overview aims to provide assistance in the classification of proteinuria and to provide guidance to the next diagnostic and therapeutic steps. The normal urine protein loss of a healthy adult is less then 150 mg/day. Higher rates of proteinuria should be confirmed as this is often a sign of glomerular or tubular damage. In addition, proteinuria is a strong prognostic factor for cardiovascular and total mortality. Principally, proteinuria is 1) a symptom of renal diseases, 2) a progression factor for renal diseases and 3) a risk factor for cardiovascular diseases and total mortality. In this article proteinuria is defined, the correlation to various renal diseases is described and the relevance for progression of renal diseases and total mortality is shown. Finally, diagnostic procedures are described and a perspective on therapeutic measures is provided.

    This chapter presents the findings arrived at by applying the resource allocation model to tuberculosis control in the Republic of Korea. Optimum subprogrammes are obtained for the four objectives of the programme: reduction of disability, impairment, excess mortality, and economic loss. These subprogrammes are discussed in terms of the content and operational level of the technologies selected and the stratum and age of the population included. The use of resources is examined in relation to the optimality of the programme. Shadow prices are introduced to provide guidance for modifying constraints in order to render the programme more effective. The feasibility of modifying the ceilings of resources and of introducing new constraints, and the significance of such variations, are discussed. Methodological problems are identified and discussed.

  16. Patients' perceptions of the interpersonal sensitivity of their healthcare providers: the potential role of patient-provider racial/ethnic concordance. (United States)

    Phillips, Karon L; Chiriboga, David A; Jang, Yuri


    Preliminary studies have revealed an association between cultural competence and an improvement in the quality of healthcare services, increased patient satisfaction, and increased effectiveness of services. This study examined factors that helped to explain patients' perceptions of their providers' interpersonal sensitivity - one component of cultural competence. The respondents were 2075 racially/ethnically diverse adults, aged 50 years and older, who responded to a national telephone survey. Results indicate that one of the main factors predicting interpersonal sensitivity is self-rated physical health: those who reported better health were more likely to see their provider as exhibiting higher levels of sensitivity. This was true for Hispanic/Latino patients. The results also suggest that having a provider of the same race/ethnicity was a significant factor only for Hispanic/Latino patients. Despite findings from previous research, racial/ethnic concordance may not be universally effective in improving interpersonal sensitivity in healthcare settings for all racial/ethnic groups.

  17. Preliminary hazards analysis -- vitrification process

    Energy Technology Data Exchange (ETDEWEB)

    Coordes, D.; Ruggieri, M.; Russell, J.; TenBrook, W.; Yimbo, P. [Science Applications International Corp., Pleasanton, CA (United States)


    This paper presents a Preliminary Hazards Analysis (PHA) for mixed waste vitrification by joule heating. The purpose of performing a PHA is to establish an initial hazard categorization for a DOE nuclear facility and to identify those processes and structures which may have an impact on or be important to safety. The PHA is typically performed during and provides input to project conceptual design. The PHA is then followed by a Preliminary Safety Analysis Report (PSAR) performed during Title 1 and 2 design. The PSAR then leads to performance of the Final Safety Analysis Report performed during the facility`s construction and testing. It should be completed before routine operation of the facility commences. This PHA addresses the first four chapters of the safety analysis process, in accordance with the requirements of DOE Safety Guidelines in SG 830.110. The hazards associated with vitrification processes are evaluated using standard safety analysis methods which include: identification of credible potential hazardous energy sources; identification of preventative features of the facility or system; identification of mitigative features; and analyses of credible hazards. Maximal facility inventories of radioactive and hazardous materials are postulated to evaluate worst case accident consequences. These inventories were based on DOE-STD-1027-92 guidance and the surrogate waste streams defined by Mayberry, et al. Radiological assessments indicate that a facility, depending on the radioactive material inventory, may be an exempt, Category 3, or Category 2 facility. The calculated impacts would result in no significant impact to offsite personnel or the environment. Hazardous materials assessment indicates that a Mixed Waste Vitrification facility will be a Low Hazard facility having minimal impacts to offsite personnel and the environment.

  18. Neuroplasticity of selective attention: Research foundations and preliminary evidence for a gene by intervention interaction. (United States)

    Isbell, Elif; Stevens, Courtney; Pakulak, Eric; Hampton Wray, Amanda; Bell, Theodore A; Neville, Helen J


    This article reviews the trajectory of our research program on selective attention, which has moved from basic research on the neural processes underlying selective attention to translational studies using selective attention as a neurobiological target for evidence-based interventions. We use this background to present a promising preliminary investigation of how genetic and experiential factors interact during development (i.e., gene × intervention interactions). Our findings provide evidence on how exposure to a family-based training can modify the associations between genotype (5-HTTLPR) and the neural mechanisms of selective attention in preschool children from lower socioeconomic status backgrounds.

  19. With Climate Change Expanding Trade Routes in the Arctic and the Resultant Pursuit of Resources, it is Crucial that the Eight Arctic Nations Find Paths Towards Sustainability and Peace in the Region. Traditional Arctic Games are an Essential Scenario that Provide an Important Scale for Analysis Aimed at Medium-long term Sustainability in the Arctic. (United States)

    Kilbourne, J. R.


    With climate change expanding trade routes in the Arctic and the resultant pursuit of oil, gas, mineral deposits, and fish, it is imperative that the eight Arctic countries find paths towards sustainability and peace in the region. Revisiting and understanding the traditional games of the indigenous people of these regions can go a long way towards helping those determining the region's future to work cooperatively towards these goals. Traditional games are an essential scenario that provide an important scale for analysis aimed at medium-long term sustainability in the Arctic. Throughout history the games we have played have been a testament about who we were, and are. From early Inuit bone and hunting games, to the gladiator contests of Ancient Rome, to the modern American game of baseball, the games we play have served as a statement of and a rehearsal for the life-world of that period and place. By reconnecting with and understanding the games of our past, we can build meaningful bridges between our past and present, and hopefully gain a better understanding of our modern world. The aforesaid are timely and important, especially as they relate to indigenous people throughout the world who are trying to preserve their traditions in a fast changing modern world. This presentation/paper will offer, based on my research and experiences in the Arctic, lessons learned from traditional Sámi and Inuit games that may help promote sustainability and peace in the Arctic world. Hopefully by acknowledging these lessons we can pursue a path forward, together reconnecting with the traditional games of the Arctic with the hope of building meaningful bridges between the past and present and moreover, helping to enhance our understanding of the important role traditional games can play in shaping an Arctic where sustainability and peace flourish.

  20. Development of a Web-based educational intervention to improve cross-cultural communication among hospice providers. (United States)

    Doorenbos, Ardith Z; Lindhorst, Taryn; Schim, Stephanie Myers; Van Schaik, Eileen; Demiris, George; Wechkin, Hope A; Curtis, J Randall


    In this article, the authors describe the theoretical foundation, development, and content of a Web-based educational intervention to improve cross-cultural communication about end-of-life concerns and report on the preliminary evaluation of this intervention using a qualitative study design. The data were collected with non-structured questions in a convenience sample of 21 hospice providers. Participants reported that they found the training appropriate and useful. Participants also reported finding the online delivery convenient and the interactive format valuable. Improving the quality of cross-cultural patient-provider communication can contribute to reducing disparities at end-of-life.

  1. Preferred provider organizations. (United States)

    Davy, J D


    The 1980s has marked the beginning of a new alternative health care delivery system: the preferred provider organization ( PPO ). This system has developed from the health maintenance organization model and is predominant in California and Colorado. A PPO is a group of providers, usually hospitals and doctors, who agree to provide health care to subscribers for a negotiated fee that is usually discounted. Preferred provider organizations are subject to peer review and strict use controls in exchange for a consistent volume of patients and speedy turnaround on claims payments. This article describes the factors leading to the development of PPOs and the implications for occupational therapy.

  4. Preliminary Iron Distribution on Vesta (United States)

    Mittlefehldt, David W.; Mittlefehldt, David W.


    The distribution of iron on the surface of the asteroid Vesta was investigated using Dawn's Gamma Ray and Neutron Detector (GRaND) [1,2]. Iron varies predictably with rock type for the howardite, eucrite, and diogenite (HED) meteorites, thought to be representative of Vesta. The abundance of Fe in howardites ranges from about 12 to 15 wt.%. Basaltic eucrites have the highest abundance, whereas, lower crustal and upper mantle materials (cumulate eucrites and diogenites) have the lowest, and howardites are intermediate [3]. We have completed a mapping study of 7.6 MeV gamma rays produced by neutron capture by Fe as measured by the bismuth germanate (BGO) detector of GRaND [1]. The procedures to determine Fe counting rates are presented in detail here, along with a preliminary distribution map, constituting the necessary initial step to quantification of Fe abundances. We find that the global distribution of Fe counting rates is generally consistent with independent mineralogical and compositional inferences obtained by other instruments on Dawn such as measurements of pyroxene absorption bands by the Visual and Infrared Spectrometer (VIR) [4] and Framing Camera (FC) [5] and neutron absorption measurements by GRaND [6].

  7. Nevada potential repository preliminary transportation strategy Study 2. Volume 1

    Energy Technology Data Exchange (ETDEWEB)



    The objectives of this study were to build on the findings of the Nevada Potential Repository Preliminary Transportation Strategy Study 1 (CRWMS M&O 1995b), and to provide additional information for input to the repository environmental impact statement (EIS) process. In addition, this study supported the future selection of a preferred rail corridor and/or heavy haul route based on defensible data, methods, and analyses. Study research did not consider proposed legislation. Planning was conducted according to the Civilian Radioactive Waste Management Program Plan (DOE 1994a). The specific objectives of Study 2 were to: eliminate or reduce data gaps, inconsistencies, and uncertainties, and strengthen the analysis performed in Study 1; develop a preliminary list of rail route evaluation criteria that could be used to solicit input from stakeholders during scoping meetings. The evaluation criteria will be revised based on comments received during scoping; restrict and refine the width of the four rail corridors identified in Study 1 to five miles or less, based on land use constraints and engineering criteria identified and established in Study 2; evaluate national-level effects of routing spent nuclear fuel and high-level waste to the four identified branch lines, including the effects of routing through or avoiding Las Vegas; continue to gather published land use information and environmental data to support the repository EIS; continue to evaluate heavy haul truck transport over three existing routes as an alternative to rail and provide sufficient information to support the repository EIS process; and evaluate secondary uses for rail (passenger use, repository construction, shared use).

    In anticipation of new observational results for Jupiter's axial moment of inertia and gravitational zonal harmonic coefficients from the forthcoming Juno orbiter, we present a number of preliminary Jupiter interior models. We combine results from ab initio computer simulations of hydrogen–helium mixtures, including immiscibility calculations, with a new nonperturbative calculation of Jupiter's zonal harmonic coefficients, to derive a self-consistent model for the planet's external gravity and moment of inertia. We assume helium rain modified the interior temperature and composition profiles. Our calculation predicts zonal harmonic values to which measurements can be compared. Although some models fit the observed (pre-Juno) second- and fourth-order zonal harmonics to within their error bars, our preferred reference model predicts a fourth-order zonal harmonic whose absolute value lies above the pre-Juno error bars. This model has a dense core of about 12 Earth masses and a hydrogen–helium-rich envelope with approximately three times solar metallicity.

  3. Providing Contraception to Adolescents. (United States)

    Raidoo, Shandhini; Kaneshiro, Bliss


    Adolescents have high rates of unintended pregnancy and face unique reproductive health challenges. Providing confidential contraceptive services to adolescents is important in reducing the rate of unintended pregnancy. Long-acting contraception such as the intrauterine device and contraceptive implant are recommended as first-line contraceptives for adolescents because they are highly effective with few side effects. The use of barrier methods to prevent sexually transmitted infections should be encouraged. Adolescents have limited knowledge of reproductive health and contraceptive options, and their sources of information are often unreliable. Access to contraception is available through a variety of resources that continue to expand. Copyright © 2015 Elsevier Inc. All rights reserved.

  5. Preliminary Benefits Assessment of Traffic Aware Strategic Aircrew Requests (TASAR) (United States)

    Henderson, Jeff; Idris, Husni; Wing, David J.


    While en route, aircrews submit trajectory change requests to air traffic control (ATC) to better meet their objectives including reduced delays, reduced fuel burn, and passenger comfort. Aircrew requests are currently made with limited to no information on surrounding traffic. Consequently, these requests are uninformed about a key ATC objective, ensuring traffic separation, and therefore less likely to be accepted than requests informed by surrounding traffic and that avoids creating conflicts. This paper studies the benefits of providing aircrews with on-board decision support to generate optimized trajectory requests that are probed and cleared of known separation violations prior to issuing the request to ATC. These informed requests are referred to as traffic aware strategic aircrew requests (TASAR) and leverage traffic surveillance information available through Automatic Dependent Surveillance Broadcast (ADS-B) In capability. Preliminary fast-time simulation results show increased benefits with longer stage lengths since beneficial trajectory changes can be applied over a longer distance. Also, larger benefits were experienced between large hub airports as compared to other airport sizes. On average, an aircraft equipped with TASAR reduced its travel time by about one to four minutes per operation and fuel burn by about 50 to 550 lbs per operation depending on the objective of the aircrew (time, fuel, or weighted combination of time and fuel), class of airspace user, and aircraft type. These preliminary results are based on analysis of approximately one week of traffic in July 2012 and additional analysis is planned on a larger data set to confirm these initial findings.

  10. Helminthiases in Montes Claros. Preliminary survey

    Directory of Open Access Journals (Sweden)

    Rina Girard Kaminsky


    Full Text Available A preliminary survey was conducted for the presence of helminths in the city of Montes Claros, M. G., Brazil. Three groups of persons were examined by the direct smear, Kato thick film and MIFC techniques; one group by direct smear and Kato only. General findings were: a high prevalence of hookworm, followed by ascariasis, S. mansoni, S. stercoralis and very light infections with T. trichiurá. E. vermicularis and H. nana were ranking parasites at an orphanage, with some hookworm and S. mansoni infections as well. At a pig slaughter house, the dominant parasites were hookworm and S. mansoni. Pig cysticercosis was an incidental finding worth mentioning for the health hazard it represents for humans as well as an economic loss. From the comparative results between the Kato and the MIF the former proved itself again as a more sensitive and reliable concentration method for helminth eggs, of low cost and easy performance.

    Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion(30%), small low density within the mass (30%), linear density (20%), pneumothorax (20%), and burrow track (20%). CT depicted cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of those CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung cancer difficult on chest radiography.

    More than 100 people participated in a discussion session at the DIS08 workshop on the topic What HERA may provide. A summary of the discussion with a structured outlook and list of desirable measurements and theory calculations is given. The HERA accelerator and the HERA experiments H1, HERMES and ZEUS stopped running in the end of June 2007. This was after 15 years of very successful operation since the first collisions in 1992. A total luminosity of {approx} 500 pb{sup -1} has been accumulated by each of the collider experiments H1 and ZEUS. During the years the increasingly better understood and upgraded detectors and HERA accelerator have contributed significantly to this success. The physics program remains in full swing and plenty of new results were presented at DIS08 which are approaching the anticipated final precision, fulfilling and exceeding the physics plans and the previsions of the upgrade program. Most of the analyses presented at DIS08 were still based on the so called HERA I data sample, i.e. data taken until 2000, before the shutdown for the luminosity upgrade. This sample has an integrated luminosity of {approx} 100 pb{sup -1}, and the four times larger statistics sample from HERA II is still in the process of being analyzed.

  13. Size, Diversification and Risk: Preliminary Evidence from Commercial Banks in Pakistan

    Directory of Open Access Journals (Sweden)

    Ayesha Afzal


    Full Text Available The aim of this paper is to provide some preliminary evidence on relation between size, diversification and risk in commercial banks of Pakistan. Using a panel of Pakistani banks, we investigated whether bigger banks are better diversified than smaller banks.The results suggested that larger banks were more diversified than their smaller counterparts mainly on account of their outreach and size of credit portfolio. On the risk side, based on accounting and market based risk measures, we explored if there is any impact of diversification on risk. We could not deduce significant result in favor of accounting risk measure of impaired lending signaling that banks find no incentive in diversification of credit books. The market based measures of VaR and Default indicator were significantly related to diversification signifying that market participants consider diversification as a relevant tool for risk mitigation. These findings have policy implications for regulators and risk management to ensure stability in financial system.

    Kim, Ji Hyung; Oh, Ki Keun; Yoon, Choon Sik; Park, Chang Yun [Yongdong Severance Hospital, Seoul (Korea, Republic of)


    The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison

  15. Preliminary characterization of abandoned septic tank systems. Volume 1

    Energy Technology Data Exchange (ETDEWEB)



    This report documents the activities and findings of the Phase I Preliminary Characterization of Abandoned Septic Tank Systems. The purpose of the preliminary characterization activity was to investigate the Tiger Team abandoned septic systems (tanks and associated leachfields) for the purpose of identifying waste streams for closure at a later date. The work performed was not to fully characterize or remediate the sites. The abandoned systems potentially received wastes or effluent from buildings which could have discharged non-domestic, petroleum hydrocarbons, hazardous, radioactive and/or mixed wastes. A total of 20 sites were investigated for the preliminary characterization of identified abandoned septic systems. Of the 20 sites, 19 were located and characterized through samples collected from each tank(s) and, where applicable, associated leachfields. The abandoned septic tank systems are located in Areas 5, 12, 15, 25, and 26 on the Nevada Test Site.

  16. CT findings of ganglioneuroma

    Jeon, Tae Joo; Yoon, Choon Sik; Kim, Myung Jun; Kim, Sang Jin; Oh, Ki Keun [Yonsei Univ., College of Medicine, Seoul (Korea, Republic of)


    Ganglioneuroma is a relatively uncommon benign tumor and has no pathognomonic radiological findings;diagnosis is therefore difficult. In order to better diagnose this tumor we analysed its CT findings and pathologic correlation. Seventeen tumors in 16 patients(M:F=3D9:7) diagnosed as ganglioneuroma between 1992 and 1996 were retrospectively analysed with regard to location, size, contour, long axis of the mass, enhancement pattern, calcification, necrosis and capsulation, all as seen on CT, and compared with histo-pathologic findings. Tumors were 1.5 to 10(mean, 5.6) cm in size, and their location was mediastinal(n=3D12), cervical(n=3D2), retroperitoneal (n=3D2) or adrenal(n=3D1). Fifteen had an oval or round contour and two were dumb-bell-shaped. The long axis of the lesion was craniocaudal in 14 cases and non-specific in three. Thirteen lesions showed heterogeneous enhancement, and four homogeneous. Capsule-like enhancement was noted on CT scans in eight cases;there was no definite correlation between enhancement pattern and pathologic findings. Calcification was seen in six cases and an inner low-density lesion in two. Ganglioneuroma is a benign neurogenic tumor, occurring most frequently at the posterior mediastinum. General CT findings of this tumor are a well-defined oval shape with a variable enhancement pattern, but several cases showed focal calcification or inner low density. For accurate diagnosis of ganglioneuroma both common and uncommon findings must therefore be considered.=20.

  18. Finding optimal exact reducts

    KAUST Repository

    AbouEisha, Hassan M.


    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

  2. Fault Management Architectures and the Challenges of Providing Software Assurance (United States)

    Savarino, Shirley; Fitz, Rhonda; Fesq, Lorraine; Whitman, Gerek


    The satellite systems Fault Management (FM) is focused on safety, the preservation of assets, and maintaining the desired functionality of the system. How FM is implemented varies among missions. Common to most is system complexity due to a need to establish a multi-dimensional structure across hardware, software and operations. This structure is necessary to identify and respond to system faults, mitigate technical risks and ensure operational continuity. These architecture, implementation and software assurance efforts increase with mission complexity. Because FM is a systems engineering discipline with a distributed implementation, providing efficient and effective verification and validation (VV) is challenging. A breakout session at the 2012 NASA Independent Verification Validation (IVV) Annual Workshop titled VV of Fault Management: Challenges and Successes exposed these issues in terms of VV for a representative set of architectures. NASA's IVV is funded by NASA's Software Assurance Research Program (SARP) in partnership with NASA's Jet Propulsion Laboratory (JPL) to extend the work performed at the Workshop session. NASA IVV will extract FM architectures across the IVV portfolio and evaluate the data set for robustness, assess visibility for validation and test, and define software assurance methods that could be applied to the various architectures and designs. This work focuses efforts on FM architectures from critical and complex projects within NASA. The identification of particular FM architectures, visibility, and associated VVIVV techniques provides a data set that can enable higher assurance that a satellite system will adequately detect and respond to adverse conditions. Ultimately, results from this activity will be incorporated into the NASA Fault Management Handbook providing dissemination across NASA, other agencies and the satellite community. This paper discusses the approach taken to perform the evaluations and preliminary findings from the

  4. Effective Bug Finding

    DEFF Research Database (Denmark)

    Rivas, Iago Abal


    Lightweight bug finders (also known as code scanners) are becoming popular, they scale well and can find simple yet common programming errors. It is now considered a good practice to integrate these tools as part of your development process. The Linux project, for instance, has an automated testing...... service, known as the Kbuild robot, that runs a few of these code scanners. In this project, I have carefully studied tens of historical Linux bugs, and I have found that many of these bugs, despite being conceptually simple, were not caught by any code scanning tool. The reason is that, by design, code...... by matching temporal bug-patterns against the control-flow graph of this program abstraction. I have implemented a proof-of-concept bug finder based on this technique, EBA, and confirmed that it is both scalable and effective at finding bugs. On a benchmark of historical Linux double-lock bugs, EBA was able...

    Assisting students to find their writing "voices" is another way to emphasize writing as a professional tool for nursing. The author discusses a teaching strategy that required students to write using a variety of styles. Students wrote fables, poetry, and letters, and used other creative writing styles to illustrate their views and feelings on professional nursing issues. Creation of a class book empowered students to see versatility with writing styles can be a powerful communication tool to use with peers, clients, and society.

  6. Heterotopic pregnancy: Sonographic findings

    Energy Technology Data Exchange (ETDEWEB)

    Kwon, Tae Hee [CHA General Hospital of Seoul, Pochon CHA University College of Medicine, Seoul (Korea, Republic of)


    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

  7. Track finding using GPUs

    CERN Document Server

    Schmitt, C; The ATLAS collaboration


    Track finding using GPUs The reconstruction and simulation of collision events is a major task in modern HEP experiments involving several ten thousands of standard CPUs. On the other hand the graphics processors (GPUs) have become much more powerful and are by far outperforming the standard CPUs in terms of floating point operations due to their massive parallel approach. The usage of these GPUs could therefore significantly reduce the overall reconstruction time per event or allow for the usage of more sophisticated algorithms. In this contribution the track finding in the ATLAS experiment will be used as an example on how the GPUs can be used in this context: the seed finding alone shows already a speed increase of one order of magnitude compared to the same implementation on a standard CPU. On the other hand the implementation on the GPU requires a change in the algorithmic flow to allow the code to work in the rather limited environment on the GPU in terms of memory, cache, and transfer speed from and to...

  11. Mammographic findings and occupational exposure to pesticides currently in use on Crete. (United States)

    Dolapsakis, G; Vlachonikolis, I G; Varveris, C; Tsatsakis, A M


    This is a preliminary report of an outreach mammographic-screening programme on Crete. The screening is part of a study to test if occupational exposure to pesticides in greenhouses (mainly organophosphates and organocarbamates), may increase the risk of malignant or premalignant findings in mammographic examination. A total of 1062 women (aged 40--75 years) were recruited between 1988 and 1993 and followed-up until 1998: 522 worked for at least 10 years in greenhouses for more than 4 h daily (exposed), and 540 never worked in agriculture (non-exposed). Statistics include detection rates and relative risks of mammographic findings. 'Exposed' women had a significantly (Pfibroadenoma, ductal hyperplasia, sclerotic adenosis, fibrohyperplastic disease, cystic disease and inflammatory mastitis. There were no significant differences in the detection rates of fibrocystic changes, lipoma and malignant changes or malignant tumours. Compared with older women (aged 50--75 years), younger women (aged 40--49 years), particularly in the 'exposed' group, had a higher detection rate of malignant tumours. These preliminary results indicate that 'exposed' women may have higher risks of incidence for a number of lesions, which are risk markers for subsequent invasive breast cancers. They confirm also that early screening for breast cancer is effective and provides an opportunity for a reduction in breast cancer mortality.

    Aycock, M.; Coordes, D.; Russell, J.; TenBrook, W.; Yimbo, P. [Science Applications International Corp., Pleasanton, CA (United States)


    This Preliminary Hazards Analysis (PHA) for the Plasma Hearth Process (PHP) follows the requirements of United States Department of Energy (DOE) Order 5480.23 (DOE, 1992a), DOE Order 5480.21 (DOE, 1991d), DOE Order 5480.22 (DOE, 1992c), DOE Order 5481.1B (DOE, 1986), and the guidance provided in DOE Standards DOE-STD-1027-92 (DOE, 1992b). Consideration is given to ft proposed regulations published as 10 CFR 830 (DOE, 1993) and DOE Safety Guide SG 830.110 (DOE, 1992b). The purpose of performing a PRA is to establish an initial hazard categorization for a DOE nuclear facility and to identify those processes and structures which may have an impact on or be important to safety. The PHA is typically performed during and provides input to project conceptual design. The PRA then is followed by a Preliminary Safety Analysis Report (PSAR) performed during Title I and II design. This PSAR then leads to performance of the Final Safety Analysis Report performed during construction, testing, and acceptance and completed before routine operation. Radiological assessments indicate that a PHP facility, depending on the radioactive material inventory, may be an exempt, Category 3, or Category 2 facility. The calculated impacts would result in no significant impact to offsite personnel or the environment. Hazardous material assessments indicate that a PHP facility will be a Low Hazard facility having no significant impacts either onsite or offsite to personnel and the environment.

    We reviewed MR images of 50 patients with spondylolisthesis to disclose MR findings of spondylolysis. In almost half of our series, spondylolysis was detected as a low signal intensity band traversing in the pairs interarticularis on both T1 and T2 weighted images. Sagittal images was superior to axial image in detection of the low signal intensity band. In some patients, a focal high signal intensity accompanying the low signal intensity band was considered to be fluid collection within pseudoarthrosis due to spondylolysis on T2-weighted image.

  2. Providing traceability for neuroimaging analyses. (United States)

    McClatchey, Richard; Branson, Andrew; Anjum, Ashiq; Bloodsworth, Peter; Habib, Irfan; Munir, Kamran; Shamdasani, Jetendr; Soomro, Kamran


    With the increasingly digital nature of biomedical data and as the complexity of analyses in medical research increases, the need for accurate information capture, traceability and accessibility has become crucial to medical researchers in the pursuance of their research goals. Grid- or Cloud-based technologies, often based on so-called Service Oriented Architectures (SOA), are increasingly being seen as viable solutions for managing distributed data and algorithms in the bio-medical domain. For neuroscientific analyses, especially those centred on complex image analysis, traceability of processes and datasets is essential but up to now this has not been captured in a manner that facilitates collaborative study. Few examples exist, of deployed medical systems based on Grids that provide the traceability of research data needed to facilitate complex analyses and none have been evaluated in practice. Over the past decade, we have been working with mammographers, paediatricians and neuroscientists in three generations of projects to provide the data management and provenance services now required for 21st century medical research. This paper outlines the finding of a requirements study and a resulting system architecture for the production of services to support neuroscientific studies of biomarkers for Alzheimer's disease. The paper proposes a software infrastructure and services that provide the foundation for such support. It introduces the use of the CRISTAL software to provide provenance management as one of a number of services delivered on a SOA, deployed to manage neuroimaging projects that have been studying biomarkers for Alzheimer's disease. In the neuGRID and N4U projects a Provenance Service has been delivered that captures and reconstructs the workflow information needed to facilitate researchers in conducting neuroimaging analyses. The software enables neuroscientists to track the evolution of workflows and datasets. It also tracks the outcomes of

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

  5. Using video games for volcanic hazard education and communication: an assessment of the method and preliminary results (United States)

    Mani, Lara; Cole, Paul D.; Stewart, Iain


    This paper presents the findings from a study aimed at understanding whether video games (or serious games) can be effective in enhancing volcanic hazard education and communication. Using the eastern Caribbean island of St. Vincent, we have developed a video game - St. Vincent's Volcano - for use in existing volcano education and outreach sessions. Its twin aims are to improve residents' knowledge of potential future eruptive hazards (ash fall, pyroclastic flows and lahars) and to integrate traditional methods of education in a more interactive manner. Here, we discuss the process of game development including concept design through to the final implementation on St. Vincent. Preliminary results obtained from the final implementation (through pre- and post-test knowledge quizzes) for both student and adult participants provide indications that a video game of this style may be effective in improving a learner's knowledge. Both groups of participants demonstrated a post-test increase in their knowledge quiz score of 9.3 % for adults and 8.3 % for students and, when plotted as learning gains (Hake, 1998), show similar overall improvements (0.11 for adults and 0.09 for students). These preliminary findings may provide a sound foundation for the increased integration of emerging technologies within traditional education sessions. This paper also shares some of the challenges and lessons learnt throughout the development and testing processes and provides recommendations for researchers looking to pursue a similar study.

    Energy Technology Data Exchange (ETDEWEB)

    Hansen, K.A. [United States Coast Guard, Groton, CT (United States). Research and Development Center


    This paper addressed the challenge of finding and recovering spills of submerged oil using current methods that often prove to be inadequate. The United States Coast Guard has launched a multi-year project to develop a complete approach for spills of submerged oils. This paper described the preliminary assessment of using sonar, laser fluorometry, real-time mass spectrometry and in-situ fluorometry to locate submerged oil. Specifications for the various techniques were also described. The authors noted that the sensors should provide enough information so that decision-makers could determine if an amount of oil sufficient to merit recovering could be identified. The systems chosen for testing for this paper were the RESON multi-beam sonar system; the Science Laser Line Scan System (LLSS) adapted for fluorescence and developed by Applications International Corporation (SAIC); fluorescence polarization developed by EIC Laboratories; and in-situ mass spectrometry and in-situ fluorometry developed by Wood Hole Oceanographic Institute (WHOI). Each of these technologies represented an improvement over the existing ad-hoc methods. Although they have not been tested in harsh environments, they may be useful immediately in some situations to increase reliability of oil detection at the bottom of, or in the water column. 16 refs., 1 tab., 20 figs.

  9. Preliminary assessment of sponge biodiversity on Saba Bank, Netherlands Antilles.

    Directory of Open Access Journals (Sweden)

    Robert W Thacker

    Full Text Available BACKGROUND: Saba Bank Atoll, Netherlands Antilles, is one of the three largest atolls on Earth and provides habitat for an extensive coral reef community. To improve our knowledge of this vast marine resource, a survey of biodiversity at Saba Bank included a multi-disciplinary team that sampled fishes, mollusks, crustaceans, macroalgae, and sponges. METHODOLOGY/PRINCIPAL FINDINGS: A single member of the dive team conducted surveys of sponge biodiversity during eight dives at six locations, at depths ranging from 15 to 30 m. This preliminary assessment documented the presence of 45 species pooled across multiple locations. Rarefaction analysis estimated that only 48 to 84% of species diversity was sampled by this limited effort, clearly indicating a need for additional surveys. An analysis of historical collections from Saba and Saba Bank revealed an additional 36 species, yielding a total of 81 sponge species recorded from this area. CONCLUSIONS/SIGNIFICANCE: This observed species composition is similar to that found on widespread Caribbean reefs, indicating that the sponge fauna of Saba Bank is broadly representative of the Caribbean as a whole. A robust population of the giant barrel sponge, Xestospongia muta, appeared healthy with none of the signs of disease or bleaching reported from other Caribbean reefs; however, more recent reports of anchor chain damage to these sponges suggests that human activities can have dramatic impacts on these communities. Opportunities to protect this extremely large habitat should be pursued, as Saba Bank may serve as a significant reservoir of sponge species diversity.

    Energy Technology Data Exchange (ETDEWEB)


    The purpose of this report is to present the preliminary findings made during the Environmental Survey, February 22--29, 1988, at the US Department of Energy (DOE) Lawrence Berkeley Laboratory (LBL) in Berkeley, California. The University of California operates the LBL facility for DOE. The LBL Survey is part of the larger DOE-wide Environmental Survey announced by Secretary John S. Herrington on September 18, 1985. The purpose of this effort is to identify, via no fault'' baseline Surveys, existing environmental problems and areas of environmental risk at DOE facilities, and to rank them on a DOE wide basis. This ranking will enable DOE to more effectively establish priorities for addressing environmental problems and allocate the resources necessary to correct them. Because the Survey is no fault'' and is not an audit,'' it is not designed to identify specific isolated incidents of noncompliance or to analyze environmental management practices. Such incidents and/or management practices will, however, be used in the Survey as a means of identifying existing and potential environmental problems. The LBL Survey was conducted by a multidisciplinary team of technical specialists headed and managed by a Team Leader and Assistant Team Leader from DOE's Office of Environmental Audit. A complete list of the LBL Survey participants and their affiliations is provided in Appendix A. 80 refs., 27 figs., 37 tabs.

There are many clinical forms of silicosis: acute silicosis, results from exposure to very large amounts of silica dust over a period of less than 2 years. Simple chronic silicosis, the most common type that we see today, results from exposure to low amounts of silica between 2 and 10 years. Chronic silicosis complicated, with silicotic conglomerates. In many cases the diagnosis of silicosis is made according to epidemiological and radiological data, without a histological confirmation. It is important to know the various radiological manifestations of silicosis to differentiate it from other lung diseases and to recognize their complications. The objective of this work is to describe typical and atypical radiological findings of silicosis and their complications in helical and high resolution (HRCT) thorax CT. Copyright © 2011 SERAM.

  15. Concept Overview & Preliminary Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Ruth, Mark


    'H2@Scale' is an opportunity for wide-scale use of hydrogen as an intermediate that carries energy from various production options to multiple uses. It is based on identifying and developing opportunities for low-cost hydrogen production and investigating opportunities for using that hydrogen across the electricity, industrial, and transportation sectors. One of the key production opportunities is use of low-cost electricity that may be generated under high penetrations of variable renewable generators such as wind and solar photovoltaics. The technical potential demand for hydrogen across the sectors is 60 million metric tons per year. The U.S. has sufficient domestic renewable resources so that each could meet that demand and could readily meet the demand using a portfolio of generation options. This presentation provides an overview of the concept and the technical potential demand and resources. It also motivates analysis and research on H2@Scale.

  16. Preliminary results of ground-motion characteristics

    Directory of Open Access Journals (Sweden)

    Francesca Bozzoni


    Full Text Available The preliminary results are presented herein for the engineering applications of the characteristics of the ground motion induced by the May 20, 2012, Emilia earthquake. Shake maps are computed to provide estimates of the spatial distribution of the induced ground motion. The signals recorded at the Mirandola (MRN station, the closest to the epicenter, have been processed to obtain acceleration, velocity and displacement response spectra. Ground-motion parameters from the MRN recordings are compared with the corresponding estimates from recent ground-motion prediction equations, and with the spectra prescribed by the current Italian Building Code for different return periods. The records from the MRN station are used to plot the particle orbit (hodogram described by the waveform. The availability of results from geotechnical field tests that were performed at a few sites in the Municipality of Mirandola prior to this earthquake of May 2012 has allowed preliminary assessment of the ground response. The amplification effects at Mirandola are estimated using fully stochastic site-response analyses. The seismic input comprises seven actual records that are compatible with the Italian code-based spectrum that refers to a 475-year return period. The computed acceleration response spectrum and the associated dispersion are compared to the spectra calculated from the recordings of the MRN station. Good agreement is obtained for periods up to 1 s, especially for the peak ground acceleration. For the other periods, the spectral acceleration of the MRN recordings exceeds that of the computed spectra.

    Preliminary neutron crystallographic data from the sweet protein thaumatin have been recorded using the LADI-III diffractometer at the Institut Laue Langevin (ILL). The results illustrate the feasibility of a full neutron structural analysis aimed at further understanding the molecular basis of the perception of sweet taste. Such an analysis will exploit the use of perdeuterated thaumatin. A preliminary neutron crystallographic study of the sweet protein thaumatin is presented. Large hydrogenated crystals were prepared in deuterated crystallization buffer using the gel-acupuncture method. Data were collected to a resolution of 2 Å on the LADI-III diffractometer at the Institut Laue Langevin (ILL). The results demonstrate the feasibility of a full neutron crystallographic analysis of this structure aimed at providing relevant information on the location of H atoms, the distribution of charge on the protein surface and localized water in the structure. This information will be of interest for understanding the specificity of thaumatin–receptor interactions and will contribute to further understanding of the molecular mechanisms underlying the perception of taste.

(Polytechnic Univ., Brooklyn, NY (United States)); Myers, G.; Cvercko, A. (Sterling Engineering, Westchester, IL (United States)); Williams, J.R. (Alfred Benesch and Co., Chicago, IL (United States))


    A preliminary design was made of a national user facility for evaluating magnetic-levitation (maglev) technologies in sizes intermediate between laboratory experiments and full-scale systems. A technical advisory committee was established and a conference was held to obtain advice on the potential requirements of operational systems and how the facility might best be configured to test these requirements. The effort included studies of multiple concepts for levitating, guiding, and propelling maglev vehicles, as well as the controls, communications, and data-acquisition and -reduction equipment that would be required in operating the facility. Preliminary designs for versatile, dual 2-MVA power supplies capable of powering attractive or repulsive systems were developed. Facility site requirements were identified. Test vehicles would be about 7.4 m (25 ft) long, would weigh form 3 to 7 metric tons, and would operate at speeds up to 67 m/s (150 mph) on a 3.3-km (2.05-mi) elevated guideway. The facility would utilize modular vehicles and guideways, permitting the substitution of levitation, propulsion, and guideway components of different designs and materials for evaluation. The vehicle would provide a test cell in which individual suspension or propulsion components or subsystems could be tested under realistic conditions. The system would allow economical evaluation of integrated systems under varying weather conditions and in realistic geometries.

  19. Spent nuclear fuel project, Cold Vacuum Drying Facility human factors engineering (HFE) analysis: Results and findings

    Energy Technology Data Exchange (ETDEWEB)

    Garvin, L.J.


    This report presents the background, methodology, and findings of a human factors engineering (HFE) analysis performed in May, 1998, of the Spent Nuclear Fuels (SNF) Project Cold Vacuum Drying Facility (CVDF), to support its Preliminary Safety Analysis Report (PSAR), in responding to the requirements of Department of Energy (DOE) Order 5480.23 (DOE 1992a) and drafted to DOE-STD-3009-94 format. This HFE analysis focused on general environment, physical and computer workstations, and handling devices involved in or directly supporting the technical operations of the facility. This report makes no attempt to interpret or evaluate the safety significance of the HFE analysis findings. The HFE findings presented in this report, along with the results of the CVDF PSAR Chapter 3, Hazards and Accident Analyses, provide the technical basis for preparing the CVDF PSAR Chapter 13, Human Factors Engineering, including interpretation and disposition of findings. The findings presented in this report allow the PSAR Chapter 13 to fully respond to HFE requirements established in DOE Order 5480.23. DOE 5480.23, Nuclear Safety Analysis Reports, Section 8b(3)(n) and Attachment 1, Section-M, require that HFE be analyzed in the PSAR for the adequacy of the current design and planned construction for internal and external communications, operational aids, instrumentation and controls, environmental factors such as heat, light, and noise and that an assessment of human performance under abnormal and emergency conditions be performed (DOE 1992a).

  20. Hyperphosphorylated tau protein in the cerebrospinal fluid of patients with Alzheimer's disease and other dementias: preliminary findings Proteína tau hiperfosforilada no líquido cefalorrraqueano de pacientes com doença de Alzheimer e outras demências: resultados preliminares

    Ana Paula Barbosa Jeronimo Hartmann


    Full Text Available Alzheimer's disease (AD is pathologically characterized by the accumulation of amyloid plaques and tau-associated neurofibrillary tangles in the cerebral tissue. The search for antemortem biomarkers is intense including analysis of cerebrospinal fluid (CSF beta-amyloid and tau proteins concentrations seeking for an accurate and early diagnosis. Levels of hyperphosphorylated tau at threonine 181 were measured in the CSF of 34 patients with AD (19 with senile AD - SAD and eight with presenile AD - PSAD and seven with other dementias (OD. The levels of CSF phosphotau were significantly higher in the AD patients compared to OD (AUC 0.812, with no association with severity of dementia, age of onset, duration of the disease or scores in the Mini-Mental State Examination. There were no differences of phosphotau levels between SAD and PSAD patients. These findings corroborate some previous studies and indicate that CSF phosphotau may help to differentiate AD from other dementias.A doença de Alzheimer (DA se caracteriza pelo achado anátomo-patológico de acúmulo de placas senis e emaranhados neurofibrilares associados à proteína tau no tecido cerebral. A pesquisa por marcadores biológicos antemortem está focada nas concentrações das proteínas beta-amilóide e tau no líquido cefalorraqueano (LCR objetivando um diagnóstico mais precoce e acurado da doença. Os níveis de proteína tau hiperfosforilada no sítio 181 foram determinados no LCR de 34 pacientes com DA (19 com DA senil - DAS e oito com DA pré-senil -DAPS e sete pacientes com outras demências (OD. Os níveis de fosfotau foram significativamente mais elevados em pacientes com DA quando comparados com OD (AUC 0,812, sem relação com gravidade da demência, idade de início, duração da doença e escores do Mini-Exame do Estado Mental. Não foram observadas diferenças entre os níveis de fosfotau em pacientes com DAS e DAPS. Estes achados corroboram os dados encontrados em estudos

    Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

  2. CT findings of fibromatoses

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Hak Nam; Choi, Yeon Hwa; Shin, Hyun Jun [Lee Rha Hospital, Chung Ju (Korea, Republic of)


    Fibromatoses constitute a group of benign fibroblastic soft tissue tumors with a tendency for local invasion and recurrence. CT provides excellent anatomic detail of soft tissue tumors and precise location, size, and extent of the tumors. The authors evaluated 7 CT scans of 6 pathologically proven aggressive fibromatoses during the last 4 years. Five lesions arose in the lower extremities: 4 in the buttocks and 1 in the thigh. One lesion arose in the upper back. The tumors were lobulated in contour and varied in size from 3.7 cm to 10.7 cm. Fibromatosis tumors were usually hypodense with muscle when no contrast medium was used and hyperdense with better delineation during infusion of the contrast medium. Three patients had recurrent disease after surgical removal. Fibromatosis may infiltrate the surrounding tissue beyond the margins, indicated on CT scans and by palpation at operation. Therefore the surgeon should plan a wide resection around the apparent limits of the fibromatosis.

  3. ADHD in college students: Developmental findings. (United States)

    Weyandt, Lisa L; Dupaul, George J


    According to the American Psychiatric Association [DSM-IV-TR, 2000], Attention-Deficit Hyperactivity Disorder (ADHD) affects approximately 3-7% of the school aged population and 2-4% of the adult population. Recently, college students with ADHD have begun to receive more attention, largely due to the increase in numbers of high school students with ADHD pursuing higher education, as well as reports of prescription stimulant misuse on college campuses. The purpose of the present article is to summarize major research findings concerning developmental issues facing college students with ADHD. Overall, findings suggest that relative to the general college population, college students with ADHD are at greater risk for academic and psychological difficulties, and misuse of prescription stimulants is indeed a problem on many campuses. Primary treatment strategies include psychostimulant medication, coaching, and educational accommodations; however, very little controlled treatment outcome research has been conducted with this population. These findings are preliminary and are tempered by methodological limitations as well as the small number of studies that have been conducted. Future research using larger sample sizes, rigorous assessment criteria, and employing longitudinal designs is needed to better understand the developmental issues facing college students with ADHD.

    Based on operational T639L60 spectral model, combined with Hybird_GSI assimilation system by using meteorological observations including radiosondes, buoyes, satellites el al., a set of Chinese Re-Analysis (CRA) datasets is developing by Chinese National Meteorological Information Center (NMIC) of Chinese Meteorological Administration (CMA). The datasets are run at 30km (0.28°latitude / longitude) resolution which holds higher resolution than most of the existing reanalysis dataset. The reanalysis is done in an effort to enhance the accuracy of historical synoptic analysis and aid to find out detailed investigation of various weather and climate systems. The current status of reanalysis is in a stage of preliminary experimental analysis. One-year forecast data during Jun 2013 and May 2014 has been simulated and used in synoptic and climate evaluation. We first examine the model prediction ability with the new assimilation system, and find out that it represents significant improvement in Northern and Southern hemisphere, due to addition of new satellite data, compared with operational T639L60 model, the effect of upper-level prediction is improved obviously and overall prediction stability is enhanced. In climatological analysis, compared with ERA-40, NCEP/NCAR and NCEP/DOE reanalyses, the results show that surface temperature simulates a bit lower in land and higher over ocean, 850-hPa specific humidity reflects weakened anomaly and the zonal wind value anomaly is focus on equatorial tropics. Meanwhile, the reanalysis dataset shows good ability for various climate index, such as subtropical high index, ESMI (East-Asia subtropical Summer Monsoon Index) et al., especially for the Indian and western North Pacific monsoon index. Latter we will further improve the assimilation system and dynamical simulating performance, and obtain 40-years (1979-2018) reanalysis datasets. It will provide a more comprehensive analysis for synoptic and climate diagnosis.

  6. Under your nose: a rare finding during dissection provides insights into maxillary supernumerary teeth. (United States)

    Redwood, C; Townsend, G C; Ghabriel, M; Brook, A H


    A supernumerary tooth was found during anatomical dissection. The position of this tooth, still impacted in the maxilla, and the associated pathology make this a rare case. During dissection by dental students of the sagittally-sectioned head of a cadaver, a supernumerary tooth was identified in the mid-palatal area. Further dissection revealed a swelling with a thin bony covering related to the crown of the tooth. The maxilla was removed en bloc and radiographic examination, CT scanning, electron microscopy and histology were undertaken. The tooth had a crenulated occlusal surface and a single root. It was 25 mm posterior to the root apex of the permanent upper central incisor. The swelling, confirmed by radiographs and CT imaging to be associated with the crown, occupied approximately one-third of the maxillary sinus. The 3D shape of the cystic lesion was visualized by a composite digital movie. The crown form, position of the tooth and the associated dentigerous cyst suggested it was a palatally developing supernumerary premolar which had been displaced to the palatal midline by the expanding cyst. This rare case highlights the learning and teaching opportunities available during dissection, showing important variations in both development and clinical anatomy. © 2014 Australian Dental Association.

  8. Finding Ernst Mayr's Plato. (United States)

    Powers, Jack


    Many biologists have accepted Ernst Mayr's claim that evolutionary biology undermined an essentialist or typological view of species that had its roots in Platonic philosophy. However, Mayr has been accused of failing to support with textual evidence his attributions to Plato of these sorts of views about biology. Contemporary work in history and philosophy of biology often seems to take onboard Mayr's account of Plato's view of species. This paper seeks to provide a critical account of putative inconsistencies between an evolutionary view of species and Platonic philosophy with renewed attention to the Platonic texts in light of recent Plato scholarship; I argue that claims that Plato held an essentialist view of species inconsistent with evolutionary biology are inadequately supported by textual evidence. If Mayr's essentialist thesis fails, one might think that the intuition that Platonic philosophy is in tension with Darwinian evolution could nonetheless be accounted for by Plato's apparent privileging of a certain sort of teleological explanation, a thesis that Mayr suggests in his 1959 paper on Louis Agassiz. However, this thesis also faces difficulties. Ernst Mayr's Plato is more likely to be found in the writings of anti-evolutionary 19th century biologists like Mayr's frequent target, Agassiz, than in a cautious reading of the Platonic dialogues themselves. Interlocutors in discussions of the history of biological thought and classificatory methods in biology should be cautious in ascribing views about biology to Plato and using terms like "Platonic essentialism."

  9. Immunological findings in autism. (United States)

    Cohly, Hari Har Parshad; Panja, Asit


    elevated in autistic brains. In measles virus infection, it has been postulated that there is immune suppression by inhibiting T-cell proliferation and maturation and downregulation MHC class II expression. Cytokine alteration of TNF-alpha is increased in autistic populations. Toll-like-receptors are also involved in autistic development. High NO levels are associated with autism. Maternal antibodies may trigger autism as a mechanism of autoimmunity. MMR vaccination may increase risk for autism via an autoimmune mechanism in autism. MMR antibodies are significantly higher in autistic children as compared to normal children, supporting a role of MMR in autism. Autoantibodies (IgG isotype) to neuron-axon filament protein (NAFP) and glial fibrillary acidic protein (GFAP) are significantly increased in autistic patients (Singh et al., 1997). Increase in Th2 may explain the increased autoimmunity, such as the findings of antibodies to MBP and neuronal axonal filaments in the brain. There is further evidence that there are other participants in the autoimmune phenomenon. (Kozlovskaia et al., 2000). The possibility of its involvement in autism cannot be ruled out. Further investigations at immunological, cellular, molecular, and genetic levels will allow researchers to continue to unravel the immunopathogenic mechanisms' associated with autistic processes in the developing brain. This may open up new avenues for prevention and/or cure of this devastating neurodevelopmental disorder.

    The work described in this report is preliminary in nature since its goal was to demonstrate the feasibility of estimating the off-gas carryover from the Defense Waste Processing Facility (DWPF) melter based on a simple mass balance using measured feed and glass pour stream (PS) compositions and time-averaged melter operating data over the duration of one canister-filling cycle. The DWPF has been in radioactive operation for over 20 years processing a wide range of high-level waste (HLW) feed compositions under varying conditions such as bubbled vs. non-bubbled and feeding vs. idling. So it is desirable to find out how the varying feed compositions and operating parameters would have impacted the off-gas entrainment. However, the DWPF melter is not equipped with off-gas sampling or monitoring capabilities, so it is not feasible to measure off-gas entrainment rates directly. The proposed method provides an indirect way of doing so.

  11. A preliminary investigation of the relationship between sensory processing and social play in autism spectrum disorder. (United States)

    Miller Kuhaneck, Heather; Britner, Preston A


    There are well-documented play deficits in autism beginning with infant object and social play. To create effective interventions, the predictors of play deficits in autism must be established. Individuals with autism spectrum disorder (ASD) frequently report sensory processing difficulties including poor praxis; however, these are potential predictors of play that have not been well studied. Using a data set of 162 individuals with ASD, this study examined the direct and indirect relationships between sensory processing and social play performance via structural equation modeling. The best fitting model suggested that sensory system functions predict praxis and play in combination, providing preliminary evidence that sensory functions are related to social play in combination with praxis in children with ASD. The findings suggest future avenues for research. [OTJR: Occupation, Participation and Health 2013;33(3):159-167.]. Copyright 2013, SLACK Incorporated.

  12. Preliminary evidence for an emotion dysregulation model of generalized anxiety disorder. (United States)

    Mennin, Douglas S; Heimberg, Richard G; Turk, Cynthia L; Fresco, David M


    Three studies provide preliminary support for an emotion dysregulation model of generalized anxiety disorder (GAD). In study 1, students with GAD reported heightened intensity of emotions, poorer understanding of emotions, greater negative reactivity to emotional experience, and less ability to self-soothe after negative emotions than controls. A composite emotion regulation score significantly predicted the presence of GAD, after controlling for worry, anxiety, and depressive symptoms. In study 2, these findings were largely replicated with a clinical sample. In study 3, students with GAD, but not controls, displayed greater increases in self-reported physiological symptoms after listening to emotion-inducing music than after neutral mood induction. Further, GAD participants had more difficulty managing their emotional reactions. Implications for GAD and psychopathology in general are discussed.

  13. A preliminary investigation of the relationship between induced rumination and state body image dissatisfaction and anxiety. (United States)

    Etu, Sarah F; Gray, James J


    The current study investigated the relationship between cognitive rumination and state body image distress using an experimental design. Specifically, the study examined whether participants induced to ruminate about an imagined negative body image event would report more body image dissatisfaction and anxiety compared to those induced to distract themselves. Ninety-nine undergraduate women completed two measures to assess depressive symptomology and baseline body image distress. All participants then silently read a body image scenario intended to evoke negative emotions. After reading the scenario, participants were randomized into one of two conditions, rumination or distraction, and were then re-administered the self-report measures. Statistical analyses revealed that the rumination group reported more state body image dissatisfaction and anxiety after the manipulation. The findings provide preliminary support for the hypothesis that a ruminative response style, specifically within a body image domain, predicts body image dissatisfaction and anxiety.

  15. Predicting Perceived Isolation among Midlife and Older LGBT Adults: The Role of Welcoming Aging Service Providers. (United States)

    Yang, Jie; Chu, Yoosun; Salmon, Mary Anne


    Older lesbian, gay, bisexual, and transgender (LGBT) adults are more likely to live alone and less likely to have children compared with their heterosexual counterparts. The lack of immediate family system can render older LGBT adults particularly vulnerable to social isolation and its consequences. The current study utilizes social exclusion theory, which asserts that not only material resources but also engagement with and inclusion into the society are necessary for marginalized people to be integrated into the mainstream. The study examines whether aging service providers (e.g., senior centers, adult day care, transportation, employment services) who are perceived by older LGBT adults as welcoming to LGBT people may reduce this population's perceived isolation. Data were collected through a needs assessment survey designed for the aging LGBT community in North Carolina. Adults aged 45 and over who self-identified as LGBT were recruited at several formal and informal groups. The survey yielded 222 valid responses. The outcome variable was perceived isolation. Key independent variables included having experienced welcoming aging service providers and living alone. After controlling for potential confounders and demographics, logistic regression results showed that having experienced welcoming aging service providers was a protective factor against perceived isolation and it also buffered the negative impact of living alone. The findings provided preliminary evidence for a new direction of intervention research-targeting LGBT cultural competence training for medical and social service providers.

    Full Text Available Phytochemical analysis of the methanolic and aqueous extracts of Faidherbia albida legumes indicated the presence of terpenes, cardiac glycosides, monosaccharides and carbohydrates type of compounds in both extracts. While alkaloids and saponins were found in aqueous extract only, flavonoids were found to be absent in both extracts. The aqueous and methanolic extracts exhibited a potent growth stimulation effect. Inhibition of both the rootlet and shoot showed a dose dependent response. Aqueous extract has a greater inhibitory effect on rootlet growth than shoot growth. The methanolic extract has a greater inhibitory effect than the aqueous extract. Both extracts and some fractions were tested against three pathogenic bacterial species; Staphylococcus aureus, Escherichia coli and Shigella dysenteriae, also tested against three pathogenic fungal species; Fusarium oxysporum, Alternaria alternate, and Aspergillus niger. Most of the plant extracts stimulate the studied fungal growth specially the aqueous extract. Meanwhile it shows interesting results by inhibiting the growth of the studied pathogenic bacterial species with most extracts and fractions.

  1. Preliminary considerations concerning actinide solubilities

    Energy Technology Data Exchange (ETDEWEB)

    Newton, T.W.; Bayhurst, B.P.; Daniels, W.R.; Erdal, B.R.; Ogard, A.E.


    Work at the Los Alamos Scientific Laboratory on the fundamental solution chemistry of the actinides has thus far been confined to preliminary considerations of the problems involved in developing an understanding of the precipitation and dissolution behavior of actinide compounds under environmental conditions. Attempts have been made to calculate solubility as a function of Eh and pH using the appropriate thermodynamic data; results have been presented in terms of contour maps showing lines of constant solubility as a function of Eh and pH. Possible methods of control of the redox potential of rock-groundwater systems by the use of Eh buffers (redox couples) is presented.

    Full Text Available Introduction: Seizure occurs in up to 10% of the population, whereas epilepsy is a chronic disease characterized by recurrent seizures that may affect up to 2% of the population. Modern neuroimaging is useful in diagnosis of  abnormalities underlying the epilepsies, but the information provided by imaging techniques can also contribute to proper classification of certain epileptic disorders and can delineate the genetics of some underlying syndromes. Neuroimaging is even more important for those patients who have medically intractable seizures. This study was carried out to establish different etiologies of seizures, to correlate the clinical data and radiological findings in cases of seizure, and to identify the common etiologies in different types of seizures. Methods: This was a retrospective hospital-based study conducted in the Department of Radiodiagnosis of Lumbini Medical College Teaching Hospital. Records of patients of past two years, admitted in any department of the hospital with history of seizure disorder and underwent a Computed Tomography  (CT of brain were included. The CT patterns were assessed and the data were tabulated and statistically analyzed. Results: There were a total of 480 cases out of which 263 (55% were male and 217 (45% were female with M:F ratio of 1.2:1. Generalized seizure was more frequent than partial seizure in both gender. In 274 cases of generalized seizures, CT scan findings were abnormal in 151 cases and normal finding observed in 123 cases. In 206 cases of partial seizures, 125 cases were abnormal and 81 having normal CT scan findings. Age wise distribution showed highest number (n=218 of cases in young group (60 yr. The most common cause of seizure  was  calcified granuloma (n=79, 16.5% followed by neurocysticercosis (NCC, n=64, 13%. Diffuse cerebral edema, sub-arachnoid hemorrhage, and hydrocephalus was seen only in lower age group particularly among 1-20 years. Infarct and diffuse cortical

  9. Identification of feigned mental retardation using the new generation of malingering detection instruments: preliminary findings. (United States)

    Graue, Lili O; Berry, David T R; Clark, Jessica A; Sollman, Myriam J; Cardi, Michelle; Hopkins, Jaclyn; Werline, Dellynda


    A recent Supreme Court decision--Atkins v. Virginia, 536 U.S. 304 (2002)--prohibiting the execution of mentally retarded (MR) defendants may have raised the attractiveness of feigning this condition in the criminal justice system. Unfortunately, very few published studies have addressed the detection of feigned MR. The present report compared results from tests of intelligence, psychiatric feigning, and neurocognitive faking in a group of 26 mild MR participants (MR) and 25 demographically matched community volunteers asked to feign MR (CVM). Results showed that the CVM suppressed their IQ scores to approximate closely the level of MR participants. WAIS-III and psychiatric malingering measures were relatively ineffective at discriminating feigned from genuine MR. Although neurocognitive malingering tests were more accurate, their reduced specificity in MR participants was of potential concern. Revised cutting scores, set to maintain a Specificity rate of about .95 in MR clients, were identified, although they require cross-validation. Overall, these results suggest that new cutting scores will likely need to be validated to detect feigned MR using current malingering instruments.

  10. Relation of Habitual Chocolate Consumption to Arterial Stiffness in a Community-Based Sample: Preliminary Findings. (United States)

    Crichton, Georgina E; Elias, Merrill F; Alkerwi, Ala'a; Stranges, Saverio; Abhayaratna, Walter P


    The consumption of chocolate and cocoa has established cardiovascular benefits. Less is known about the effects of chocolate on arterial stiffness, a marker of subclinical cardiovascular disease. The aim of this study was to investigate whether chocolate intakes are independently associated with pulse wave velocity (PWV), after adjustment for cardiovascular, lifestyle and dietary factors. Prospective analyses were undertaken on 508 community-dwelling participants (mean age 61 years, 60% women) from the Maine-Syracuse Longitudinal Study (MSLS). Habitual chocolate intakes, measured using a food frequency questionnaire, were related to PWV, measured approximately 5 years later. Chocolate intake was significantly associated with PWV in a non-linear fashion with the highest levels of PWV in those who never or rarely ate chocolate and lowest levels in those who consumed chocolate once a week. This pattern of results remained and was not attenuated after multivariate adjustment for diabetes, cardiovascular risk factors and dietary variables (p = 0.002). Weekly chocolate intake may be of benefit to arterial stiffness. Further studies are needed to explore the underlying mechanisms that may mediate the observed effects of habitual chocolate consumption on arterial stiffness.

  13. Aerobic exercise increases hippocampal volume and improves memory in multiple sclerosis: preliminary findings. (United States)

    Leavitt, V M; Cirnigliaro, C; Cohen, A; Farag, A; Brooks, M; Wecht, J M; Wylie, G R; Chiaravalloti, N D; DeLuca, J; Sumowski, J F


    Multiple sclerosis leads to prominent hippocampal atrophy, which is linked to memory deficits. Indeed, 50% of multiple sclerosis patients suffer memory impairment, with negative consequences for quality of life. There are currently no effective memory treatments for multiple sclerosis either pharmacological or behavioral. Aerobic exercise improves memory and promotes hippocampal neurogenesis in nonhuman animals. Here, we investigate the benefits of aerobic exercise in memory-impaired multiple sclerosis patients. Pilot data were collected from two ambulatory, memory-impaired multiple sclerosis participants randomized to non-aerobic (stretching) and aerobic (stationary cycling) conditions. The following baseline/follow-up measurements were taken: high-resolution MRI (neuroanatomical volumes), fMRI (functional connectivity), and memory assessment. Intervention was 30-minute sessions 3 times per week for 3 months. Aerobic exercise resulted in 16.5% increase in hippocampal volume and 53.7% increase in memory, as well as increased hippocampal resting-state functional connectivity. Improvements were specific, with no comparable changes in overall cerebral gray matter (+2.4%), non-hippocampal deep gray matter structures (thalamus, caudate: -4.0%), or in non-memory cognitive functioning (executive functions, processing speed, working memory: changes ranged from -11% to +4%). Non-aerobic exercise resulted in relatively no change in hippocampal volume (2.8%) or memory (0.0%), and no changes in hippocampal functional connectivity. This is the first evidence for aerobic exercise to increase hippocampal volume and connectivity and improve memory in multiple sclerosis. Aerobic exercise represents a cost-effective, widely available, natural, and self-administered treatment with no adverse side effects that may be the first effective memory treatment for multiple sclerosis patients.

    Gerra, G; Zaimovic, A; Sartori, R; Raggi, M A; Bocchi, C; Zambelli, U; Timpano, M; Zanichelli, V; Delsignore, R; Brambilla, F


    This study was conducted to determine the nature of the reaction of nonalcoholic adult children of alcoholic (ACOA) fathers to the experimental induction of aggression. Of particular interest was the relationship between biochemical factors and personality traits during a stressful event experienced by persons at risk for alcoholism. Aggression was induced by a modified free-operant procedure in 14 ACOA and 14 non-ACOA subjects between 18 and 19 years of age with men and women represented in equal numbers. Neurotransmitter-hormonal assays from blood drawn immediately before, and 20 and 30 minutes after, starting the test included norepinephrine (NE), epinephrine (EPI), prolactin (PRL), growth hormone (GH) and cortisol (Cort). Personality traits were assessed by the Minnesota Multiphasic Personality Inventory (MMPI) Tridimensional Personality Questionnaire (TPQ) and the Buss-Durkee Hostility Inventory (BDHI). During the aggression induction session, ACOAs gained (F = 4.6, 1/13 df, p aggressiveness among ACOAs. Higher baseline plasma levels of Cort (F = 9.8, 1/13 df, p aggression in ACOAs in association with monoaminergic and endocrine changes.

  16. Experimentally manipulated sleep duration in adolescents with asthma: Feasibility and preliminary findings. (United States)

    Meltzer, Lisa J; Faino, Anna; Szefler, Stanley J; Strand, Matthew; Gelfand, Erwin W; Beebe, Dean W


    To examine the impact of sleep duration on lung function and asthma symptoms in adolescents. Ten adolescents with asthma (60% female, 60% Caucasian, mean age = 13.7 years, range 12-17) completed a 3-week randomized, cross-over sleep manipulation protocol. Following a week of self-selected sleep duration, adolescents were randomized to a five-night deficient sleep opportunity (6.5 hr in bed) or a healthy sleep opportunity (10 hr in bed) obtained by systematically changing bedtimes. Wake time remained consistent across all 3 weeks (including weekends). Daily reports of sleep patterns and asthma symptoms, actigraphy, and daily peak expiratory flow rates (PEFR), as well as weekly spirometry and exhaled nitric oxide were collected. Participants averaged 3.2 hr less sleep (P sleep condition versus the long sleep condition. Further, they had an 8.4% decrease overnight in PEFR (P = 0.007), and reported more asthma symptoms interfering with activities in the past 24 hr (P = 0.02) in the short sleep condition than the long sleep condition. No significant differences between experimental weeks were found for weekly spirometry or exhaled nitric oxide. This pilot study demonstrated the feasibility of a cross-over sleep manipulation protocol in adolescents with asthma. Since overnight decrease in PEFR is a marker of nocturnal asthma, and has been associated with the severity of daytime airflow limitation, these early-stage results suggest that shortened sleep duration may exacerbate adolescent asthma and associated functional impairments. © 2015 Wiley Periodicals, Inc.

  17. Paediatric cardiac CT examinations: impact of the iterative reconstruction method ASIR on image quality - preliminary findings

    Energy Technology Data Exchange (ETDEWEB)

    Mieville, Frederic A. [University Hospital Center and University of Lausanne, Institute of Radiation Physics, Lausanne (Switzerland); University Hospital Center and University of Lausanne, Institute of Radiation Physics - Medical Radiology, Lausanne (Switzerland); Gudinchet, Francois; Rizzo, Elena [University Hospital Center and University of Lausanne, Department of Radiology, Lausanne (Switzerland); Ou, Phalla; Brunelle, Francis [Necker Children' s Hospital, Department of Radiology, Paris (France); Bochud, Francois O.; Verdun, Francis R. [University Hospital Center and University of Lausanne, Institute of Radiation Physics, Lausanne (Switzerland)


    Radiation dose exposure is of particular concern in children due to the possible harmful effects of ionizing radiation. The adaptive statistical iterative reconstruction (ASIR) method is a promising new technique that reduces image noise and produces better overall image quality compared with routine-dose contrast-enhanced methods. To assess the benefits of ASIR on the diagnostic image quality in paediatric cardiac CT examinations. Four paediatric radiologists based at two major hospitals evaluated ten low-dose paediatric cardiac examinations (80 kVp, CTDI{sub vol} 4.8-7.9 mGy, DLP 37.1-178.9 The average age of the cohort studied was 2.6 years (range 1 day to 7 years). Acquisitions were performed on a 64-MDCT scanner. All images were reconstructed at various ASIR percentages (0-100%). For each examination, radiologists scored 19 anatomical structures using the relative visual grading analysis method. To estimate the potential for dose reduction, acquisitions were also performed on a Catphan phantom and a paediatric phantom. The best image quality for all clinical images was obtained with 20% and 40% ASIR (p < 0.001) whereas with ASIR above 50%, image quality significantly decreased (p < 0.001). With 100% ASIR, a strong noise-free appearance of the structures reduced image conspicuity. A potential for dose reduction of about 36% is predicted for a 2- to 3-year-old child when using 40% ASIR rather than the standard filtered back-projection method. Reconstruction including 20% to 40% ASIR slightly improved the conspicuity of various paediatric cardiac structures in newborns and children with respect to conventional reconstruction (filtered back-projection) alone.

  18. Distribution of hyperpolarized xenon in the brain following sensory stimulation: preliminary MRI findings.

    Directory of Open Access Journals (Sweden)

    Mary L Mazzanti

    Full Text Available In hyperpolarized xenon magnetic resonance imaging (HP (129Xe MRI, the inhaled spin-1/2 isotope of xenon gas is used to generate the MR signal. Because hyperpolarized xenon is an MR signal source with properties very different from those generated from water-protons, HP (129Xe MRI may yield structural and functional information not detectable by conventional proton-based MRI methods. Here we demonstrate the differential distribution of HP (129Xe in the cerebral cortex of the rat following a pain stimulus evoked in the animal's forepaw. Areas of higher HP (129Xe signal corresponded to those areas previously demonstrated by conventional functional MRI (fMRI methods as being activated by a forepaw pain stimulus. The percent increase in HP (129Xe signal over baseline was 13-28%, and was detectable with a single set of pre and post stimulus images. Recent innovations in the production of highly polarized (129Xe should make feasible the emergence of HP (129Xe MRI as a viable adjunct method to conventional MRI for the study of brain function and disease.

  19. Quantitation of heavy ion damage to the mammalian brain - Some preliminary findings (United States)

    Cox, A. B.; Kraft, L. M.


    For several years, studies have been conducted regarding late effects of particulate radiations in mammalian tissues, taking into account the brains of rodents and lagomorphs. Recently, it has become feasible to quantify pathological damage and morpho-physiologic alterations accurately in large numbers of histological specimens. New investigative procedures make use of computer-assisted automated image analysis systems. Details regarding the employed methodology are discussed along with the results of the information. The radiations of high linear energy transfer (LET) cause apparently earlier and more dramatic shrinkage of olfactory glomeruli in exposed rabbit brains than comparable doses of Co-60 gamma photons.

  1. Family history and psychiatric comorbidity in persons with compulsive buying: preliminary findings. (United States)

    Black, D W; Repertinger, S; Gaffney, G R; Gabel, J


    The authors explored the family history and psychiatric comorbidity of a group of compulsive buyers who volunteered for medication studies. Compulsive buying is characterized by inappropriate shopping and spending behavior that leads to impairment. Thirty-three subjects who met the criteria of McElroy and colleagues for compulsive buying, and who scored more than two standard deviations above the mean on the Compulsive Buying Scale, were recruited. Twenty-two comparison subjects were recruited in the course of another study, and the presence of obsessive-compulsive disorder was the only reason for exclusion. Both groups were administered the Structured Clinical Interview for DSM-III-R disorders. The Family History Research Diagnostic Criteria were used to collect information about psychiatric disorders in first-degree relatives. Compulsive buyers had a mean age of 40 years; two (6%) were men. Comparison subjects had a mean age of 39 years; six (27%) were men. The two groups differed in gender distribution but not in age, marital status, or educational achievement. Compulsive buyers were more likely than comparison subjects to have lifetime mood disorders (especially major depression) and to have more than one psychiatric disorder. First-degree relatives of compulsive buyers were more likely than comparison relatives to suffer from depression, alcoholism, and a drug use disorder and to suffer more psychiatric disorders in general. These results indicate that persons who report compulsive buying behavior, and their first-degree relatives, are more likely to have a higher prevalence of psychiatric disorder than are comparison subjects.

  3. Cognition in Adult Bereavement: Preliminary Findings From Five Hospice Bereavement Focus Groups. (United States)

    Harris, Helen; Lee, Christina; Yancey, Gaynor


    Grief is an experience of both common and unique responses (Hooyman & Kramer, 2006). Grief affects people in various ways including emotionally, cognitively, socially, physically, and spiritually (Corr, 2007; Doka, 2014). Little has been published on the cognitive domain of loss affecting attention, and concentration of bereaved adults. This qualitative study explored these effects among adults in one hospice bereavement program in Central Texas. Five focus groups included facilitated bereavement topical conversations resulting in descriptions of memory, concentration, and attention deficits after loss. These results suggested that participation in bereavement programming may normalize the experience facilitating cognitive task accomplishment. Referrals for bereavement care may be appropriate in order to facilitate equilibrium in individual's lives following a significant death.

    Full Text Available Introduction Fishing, one of the oldest productive activities, is an important sector of the national and world economy. Aim To evaluate the vestibular behavior in a population of fishermen. Methods In a retrospective and cross-sectional study, 13 fishermen (mean 45.0, between 33 and 62 years of age, were submitted to anamnesis, otorhinolaryngological evaluation, and vestibular exam through the vector electronystagmography. Results The most evident otoneurologic symptoms were hearing loss (76.9%, tinnitus (61.7%, dizziness (46.1%, and headache (46.1%. The most evident clinical symptoms were fatigue (46.1%, depression (23.0%, anxiety (15.3%, insomnia (7.7%, and agitation during sleep (7.7%. There were alterations in the vestibular exam in 5 fishermen (38.5% discovered in the caloric test. There was a prevalence of alteration in the peripheral vestibular system. There was a major frequency of the peripheral vestibular irritative syndrome. Conclusion The otoneurologic complaints were frequent in the population studied to verify the importance of allowing labyrinth exams and the need for adopting preventive measures relating to noise exposure as well as carbon monoxide exposure, because they can cause and/or enhance various manifestations of labyrinthine vestibular impairment that can affect the quality of life of these workers.

    Full Text Available Poverty should be defined, measured, and scrutinized its root causes from a multi-dimension perspectives. Therefore, in designing and implementation of poverty alleviation program, it should consider economic factors, social and political contexts surrounding the poor. Sen (1982; 1999 views poverty as a multifaceted world and ethical dimension essentially should be placed underpinning it as a vital economic problem. The paper takes the stance that the poor themselves have potential capacity to alleviate their condition in resolving poverty trap. Community development program is one of the strategies to deal with the poverty problem. Islamic microfinance can play an important role in combating poverty dilemma especially in Muslim majority population communities. Through the approach proposed by Bigg and Satterthwaite (2005 with strengthening local organizations and community development programs, Islamic microfinance should engage a strategic partnership with the Masjid and Islamic charity institutions (zakat and waqf organization. This strategic alliance will result more integrated programs and also capacity building of the institutions involved. This paper aims to contribute a grass root model in the purpose of combating poverty in the framework of Islamic economic system. =========================================== Kemiskinan harus didefinisikan, diukur, dan diteliti akar penyebabnya dari berbagai perspektif. Oleh karena itu, dalam merancang dan mengimplementasikan program pengentasan kemiskinan, faktor-faktor ekonomi, konteks sosial dan politik yang mengelilingi kemiskinan juga harus dipertimbangkan. Sen (1982; 1999 memandang kemiskinan sebagai sebuah dunia yang kompleks, dan dimensi dasar etika harus ditempatkan sebagai sebuah masalah ekonomi yang vital. Peneliti sendiri dalam hal ini berpandangan bahwa orang-orang miskin pada dasarnya punya kapasitas yang memadai untuk keluar dari garis kemiskinan. Salah satunya adalah dengan program pengembangan masyarakat yang merupakan satu strategi dalam pengentasan kemiskinan. Keuangan mikro syariah dapat memainkan peran penting dalam memerangi dilema kemiskinan, khususnya di daerah-daerah yang mayoritas penduduknya Muslim. Pendekatan yang diusulkan oleh Bigg dan Satterthwaite (2005 adalah dengan cara penguatan organisasi lokal dan program pengembangan masyarakat dimana keuangan mikro syariah harus terlibat dalam kemitraan-kemitraan strategis dengan masjid-masjid dan lembaga-lembaga sosial lainnya (seperti lembaga zakat dan wakaf.

  13. Do recently diagnosed black breast cancer patients find questions about cancer fatalism acceptable? A preliminary report. (United States)

    Sheppard, Vanessa B; Davis, Kimberly; Boisvert, Marc; Boisvert, Mare; Jennings, Yvonne; Montalvo, Becky


    Socio-cultural factors such as cancer fatalism have been understudied in cancer patients. Women from two cancer centers completed a structured phone survey and an open-ended cognitive interview. Socio-cultural variables of fatalism, hope, and spiritual coping were measured using standardized scales. Older women had significantly higher fatalism scores compared to younger women (p Fatalism rates were low. Ratings of hope and collaborative religious coping were high (m = 20, m = 35, respectively). Qualitative comments confirmed the overall low acceptability of the fatalism measures. Further research is needed to identify measures that are acceptable to newly diagnosed patients.

  14. Preference of stevia level in Coca Cola: Preliminary findings in 50+ year olds

    Panovská, Zdenka; Grosová, Stanislava; Sudzina, Frantisek


    Coca Cola Life was first introduced in Argentina in June 2013. In the following 15 months, it was launched also in Chile, Sweden, and the U.K. Since January 2015, it is available in many but not all countries. In the version of Coca Cola Life, which was produced till December 2016, 35% of sugar...... was replaced by stevia. In the version produced since January 2017, 45% of sugar is replaced by stevia. This opened a limited time-frame for studying preferences between regular Coca Cola, Coca Cola Life with 35% of stevia, and Coca Cola Life with 45% of stevia. The aim of the paper is to investigate if Big...... Five Inventory personality traits, gender, age, smoking, and drinking of any cola in general influence preferred amount of stevia. The research was conducted in the Czech Republic where Coca Cola Life is not available, so all respondents are equally unaware of (or equally not used to) the taste. All...

  16. Glucosamine sulfate effect on the degenerated patellar cartilage: preliminary findings by pharmacokinetic magnetic resonance modeling

    Energy Technology Data Exchange (ETDEWEB)

    Marti-Bonmati, Luis [Dr Peset University Hospital, Radiology Department, Valencia (Spain); Hospital Quiron Valencia, Radiology Department, Valencia (Spain); Sanz-Requena, Roberto; Alberich-Bayarri, Angel [Hospital Quiron Valencia, Radiology Department, Valencia (Spain); Rodrigo, Jose Luis [Dr Peset University Hospital, Traumatology and Orthopedics Surgery Department, Valencia (Spain); Carot, Jose Miguel [Universidad Politecnica de Valencia, EIO Department, Valencia (Spain)


    Normal and degenerated cartilages have different magnetic resonance (MR) capillary permeability (K{sup trans}) and interstitial interchangeable volume (v{sub e}). Our hypothesis was that glucosamine sulfate treatment modifies these neovascularity abnormalities in osteoarthritis. Sixteen patients with patella degeneration, randomly distributed into glucosamine or control groups, underwent two 1.5-Tesla dynamic contrast-enhanced MR imaging studies (treatment initiation and after 6 months). The pain visual analog scale (VAS) and American Knee Society (AKS) score were used. A two-compartment pharmacokinetic model was used. Percentages of variations (postreatment-pretreatment/pretreatment) were compared (t-test for independent data). In the glucosamine group, pain and functional outcomes statistically improved (VAS: 7.3 {+-} 1.1 to 3.6 {+-} 1.3, p < 0.001; AKS: 18.6 {+-} 6.9 to 42.9 {+-} 2.7, p < 0.01). Glucosamine significantly increased K{sup trans} at 6 months (-54.4 {+-} 21.2% vs 126.7 {+-} 56.9%, p < 0.001, control vs glucosamine). In conclusion, glucosamine sulfate decreases pain while improving functional outcome in patients with cartilage degeneration. Glucosamine sulfate increases K{sup trans}, allowing its proposal as a surrogate imaging biomarker after 6 months of treatment. (orig.)

  18. Voxel-based morphometry findings in Alzheimer's disease: neuropsychiatric symptoms and disability correlations - preliminary results

    Directory of Open Access Journals (Sweden)

    Luciano de Gois Vasconcelos


    Full Text Available INTRODUCTION: The role of structural brain changes and their correlations with neuropsychiatric symptoms and disability in Alzheimer's disease are still poorly understood. OBJECTIVE: To establish whether structural changes in grey matter volume in patients with mild Alzheimer's disease are associated with neuropsychiatric symptoms and disability METHODS: Nineteen Alzheimer's disease patients (9 females; total mean age =75.2 y old +4.7; total mean education level =8.5 y +4.9 underwent a magnetic resonance imaging (MRI examination and voxel-based morphometry analysis. T1-weighted images were spatially normalized and segmented. Grey matter images were smoothed and analyzed using a multiple regression design. The results were corrected for multiple comparisons. The Neuropsychiatric Inventory was used to evaluate the neuropsychiatric symptoms, and the Functional Activities Questionnaire and Disability Assessment for Dementia were used for functional evaluation RESULTS: A significant negative correlation was found between the bilateral middle frontal gyri, left inferior temporal gyrus, right orbitofrontal gyrus, and Neuropsychiatric Inventory scores. A negative correlation was found between bilateral middle temporal gyri, left hippocampus, bilateral fusiform gyri, and the Functional Activities Questionnaire. There was a positive correlation between the right amygdala, bilateral fusiform gyri, right anterior insula, left inferior and middle temporal gyri, right superior temporal gyrus, and Disability Assessment for Dementia scores CONCLUSIONS: The results suggest that the neuropsychiatric symptoms observed in Alzheimer's disease patients could be mainly due to frontal structural abnormalities, whereas disability could be associated with reductions in temporal structures.

  19. Siberian Ibex ( Capra sibirica Home Ranges in Ikh Nart Nature Reserve, Mongolia: Preliminary Findings

    Directory of Open Access Journals (Sweden)

    Richard P. Reading


    Full Text Available Siberian ibex ( Capra sibirica remain poorly understood, as little is known about their ecology . W e began studying ibex in Ikh Nart Nature Reserve, Dornogobi Aimag, Mongolia to better understand the species’ ecological needs and threats. In this paper we report on home range and core range sizes. We captured 27 ibex and fi t them with radio telemetry collars using drive nets for adults and juveniles ( n = 22 and hand captures for neonatal kids ( n = 5 . W e collected 1,029 locations from September 2003 to February 2007. Throughout the study, 9 ibex with 40+ fi xe s used mean, annual home range sizes of 3,115.5 ± 504.2 ha using the Minimum Convex Polygon method. Home ranges calculated using the fi xe d kernel method were smaller: 475.9 ± 14.7 ha for 50% kernel and 1,808.0 ± 88.1 ha for 95% kernel. Ibex from different demographic groups (males vs. females and juveniles vs. adults used remarkably similar home and core ranges; we found no signifi ca nt differences among any demographic groups. Although not quantifi ed , ibex mostly restricted their activities to areas with steep cliffs and rocky outcrops and home ranges overlapped extensively.

  20. Distribution of Hyperpolarized Xenon in the Brain Following Sensory Stimulation: Preliminary MRI Findings (United States)

    Mazzanti, Mary L.; Walvick, Ronn P.; Zhou, Xin; Sun, Yanping; Shah, Niral; Mansour, Joey; Gereige, Jessica; Albert, Mitchell S.


    In hyperpolarized xenon magnetic resonance imaging (HP 129Xe MRI), the inhaled spin-1/2 isotope of xenon gas is used to generate the MR signal. Because hyperpolarized xenon is an MR signal source with properties very different from those generated from water-protons, HP 129Xe MRI may yield structural and functional information not detectable by conventional proton-based MRI methods. Here we demonstrate the differential distribution of HP 129Xe in the cerebral cortex of the rat following a pain stimulus evoked in the animal's forepaw. Areas of higher HP 129Xe signal corresponded to those areas previously demonstrated by conventional functional MRI (fMRI) methods as being activated by a forepaw pain stimulus. The percent increase in HP 129Xe signal over baseline was 13–28%, and was detectable with a single set of pre and post stimulus images. Recent innovations in the production of highly polarized 129Xe should make feasible the emergence of HP 129Xe MRI as a viable adjunct method to conventional MRI for the study of brain function and disease.

  1. Antisocial and Schizoid Personality Disorder Scales: Conceptual bases and preliminary findings

    Directory of Open Access Journals (Sweden)

    Octav - Sorin Căndel


    Full Text Available The study describes the development and validation of two scales which can be used in evaluating schizoid and antisocial personality disorders. Both scales were developed relying on descriptions from DSM 5 and ICD 10. For validation, the scales have been tested on 125 subjects, together with two well-known psychometric instruments, DA12profile Personality Inventory, and SCL-90. Internal consistency is calculated using Cronbach's alpha coefficient. Schizoid Scale contains 20 items and shows a good internal consistency (Cronbach's α = .77 and Antisocial Scale contains 22 items and has excellent internal consistency (Cronbach's α = .91. The correlations between the scores of the two scales and the scores of DA12profile Personality Inventory and SCL-90 are statistically significant. The factorial analysis reveals that the two scales and DA12profile Personality Inventory sub-scales are clustered in four factors, explaining 68.31 % of the variance. Based on these results, we discussed the importance the scales have for psychological research and for psycho-diagnostic, their limitations and our future directions of research.

  3. Preliminary Findings Show Maternal Hypothyroidism May Contribute to Abnormal Cortical Morphology in Offspring

    Directory of Open Access Journals (Sweden)

    Julieta E. Lischinsky


    Full Text Available In rodents, insufficient thyroid hormone (TH gestationally has adverse effects on cerebral cortex development. Comparable studies of humans examining how TH insufficiency affects cortical morphology are limited to children with congenital hypothyroidism or offspring of hypothyroxinemic women; effects on cortex of children born to women with clinically diagnosed hypothyroidism are not known. We studied archived MRI scans from 22 children aged 10 to 12 years born to women treated for preexisting or de novo hypothyroidism within pregnancy (HYPO and 24 similar age and sex controls from euthyroid women. FreeSurfer Image Analysis Suite software was used to measure cortical thickness (CT and a vertex-based approach served to compare HYPO versus control groups and Severe versus Mild HYPO subgroups as well as to perform regression analyses examining effects of trimester-specific maternal TSH on CT. Results showed that relative to controls, HYPO had multiple regions of both cortical thinning and thickening, which differed for left and right hemispheres. In HYPO, thinning was confined to medial and mid-lateral regions of each hemisphere and thickening to superior regions (primarily frontal of the left hemisphere and inferior regions (particularly occipital and temporal of the right. The Severe HYPO subgroup showed more thinning than Mild in frontal and temporal regions and more thickening in bilateral posterior and frontal regions. Maternal TSH values predicted degree of thinning and thickening within multiple brain regions, with the pattern and direction of correlations differing by trimester. Notably, some correlations remained when cases born to women with severe hypothyroidism were removed from the analyses suggesting mild variations of maternal TH may permanently affect offspring cortex. We conclude that maternal hypothyroidism during pregnancy has long-lasting manifestations on the cortical morphology of their offspring with specific effects reflecting both severity and timing of maternal TH insufficiency.

  5. Preliminary findings of similarities and differences in the signed and spoken language of children with autism. (United States)

    Shield, Aaron


    Approximately 30% of hearing children with autism spectrum disorder (ASD) do not acquire expressive language, and those who do often show impairments related to their social deficits, using language instrumentally rather than socially, with a poor understanding of pragmatics and a tendency toward repetitive content. Linguistic abnormalities can be clinically useful as diagnostic markers of ASD and as targets for intervention. Studies have begun to document how ASD manifests in children who are deaf for whom signed languages are the primary means of communication. Though the underlying disorder is presumed to be the same in children who are deaf and children who hear, the structures of signed and spoken languages differ in key ways. This article describes similarities and differences between the signed and spoken language acquisition of children on the spectrum. Similarities include echolalia, pronoun avoidance, neologisms, and the existence of minimally verbal children. Possible areas of divergence include pronoun reversal, palm reversal, and facial grammar. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

  6. Methylphenidate normalizes emotional processing in adult patients with attention-deficit/hyperactivity disorder: preliminary findings. (United States)

    Conzelmann, Annette; Woidich, Eva; Mucha, Ronald F; Weyers, Peter; Jacob, Christian P; Lesch, Klaus-Peter; Pauli, Paul


    Emotional-motivational dysfunctions may significantly contribute to symptoms of attention-deficit/hyperactivity disorder (ADHD). Hyperactive-impulsive symptoms and sensation seeking could be the result of a search for reinforcers, and cognitive dysfunctions might be due to a low motivational drive. Emotional-motivational dysfunctions could also explain social dysfunctions in ADHD patients because they may lead to misinterpretations of emotional and social clues. Since methylphenidate (MPH) is the first choice as a pharmacological treatment in ADHD, we examined its influence on dysfunctional emotional processes. 13 adult ADHD patients were examined twice, without and after intake of MPH according to their personal medication regimen. The affect-modulated startle paradigm was used to assess physiological (affect-modulated startle response) and subjective (valence and arousal ratings) responses to pleasant, neutral and unpleasant visual stimuli. Healthy controls displayed affective startle modulation as expected, with startle attenuation and potentiation while watching pleasant and unpleasant pictures, respectively. In contrast, unmedicated ADHD patients displayed deficient responses to pleasant stimuli; no startle attenuation during the exposure to pleasant pictures was observed. However, MPH reinstated a normal affective startle modulation, as indicated by attenuation and potentiation associated with pleasant and unpleasant pictures, respectively. Valence and arousal ratings of patients were not affected by MPH. The data suggest that MPH as first choice treatment in ADHD has a positive impact on emotional processes in adult ADHD patients and points to the clinical relevance of emotional-dysfunctions in ADHD.

  7. Study addiction - a new area of psychological study: conceptualization, assessment, and preliminary empirical findings


    Atroszko, PA; Andreassen, CS; Griffiths, M.; Pallesen, S


    Aims: Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to ‘study addiction’. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. Methods: The Bergen Study Addiction Scale (BStAS) was tested - reflecting se...

  8. Understanding employers' hiring intentions in relation to qualified workers with disabilities: preliminary findings. (United States)

    Fraser, Robert T; Johnson, Kurt; Hebert, James; Ajzen, Icek; Copeland, Jana; Brown, Pat; Chan, Fong


    As part of the planning process for a larger survey study to examine factors affecting employers' intention to hire and hiring of people with disabilities, a series of three semi-structured focus groups were held with key hiring decision makers, such as Human Resources directors, Chief Operating Officers (COOs), or Chief Executive Officers (CEOs) of small, medium, and large Seattle area companies. The chief goals of the focus groups were to elicit and refine the participants' beliefs, normative influences, and perceived control relative to hiring workers with disabilities. Narrative data obtained from the focus group discussion were examined using the Theory of Planned Behavior (TPB) to identify themes expressed by the focus group participants within the context of company size. Themes did vary by company size, but a prevailing concern across all companies related to questions about the efficiency/effectiveness of contact with vocational rehabilitation agencies. For both small- and mid-sized companies, there was a belief that people with disabilities could not do the work or were somehow less qualified. For large companies, convincing departmental and team managers that outreaching workers with disabilities would be a worthwhile hiring practice remained a challenge. The themes derived from this study can be used to help occupational rehabilitation professionals develop educational and marketing interventions to improve employers' attitudes toward hiring and retaining individuals with disabilities.

  9. An Unexpected Means of Embedding Ethics in Organizations: Preliminary Findings from Values-Based Evaluations

    Directory of Open Access Journals (Sweden)

    Gemma Burford


    Full Text Available Ethical principles constitute a crucial area of debate and discussion in the global conversation around transitions to sustainability, and of particular relevance to the contribution of businesses and other organizations. Scholars in business ethics have recently identified several challenges in this area, such as problems of measurement, rigor, and meaningfulness to practitioners; corporate social responsibility; and institutionalization of ethics in businesses. In this paper, the impacts of a pragmatic values-based evaluation approach originally developed in another field—education for sustainable development—are shown to strongly contribute to many of these challenges. Impacts found across eight organizations include (i deep values conceptualization; (ii increased esteem (iii building capacity for assessment of values-based achievements; (iv values mainstreaming; and (v effective external values communications. It seems that the in-situ development and use of values-based indicators helped to conceptualize locally shared values that underpin decisions, thus embedding the application of (local ethics. Although this study is exploratory, it is clear that the values-based approach shows promise for meeting key challenges in business ethics and wider sustainability, and for new directions for future cross-disciplinary research.

    Fenech, A; Dendy, P P; Hussey, J K; Bennett, B; Douglas, A S


    Platelets from eight patients thought clinically to have deep venous thrombosis were labbelled with indium-111 and reinjected. Subsequent scanning of the patients with a wholebody scanner and imaging with a gammacamera showed focal accumulation of the label at five sites in four legs, which correlated precisely with the sites of venous thrombi identified by ascending venography. This technique is a useful addition to methods for diagnosis venous thrombosis. Images FIG 1 FIG 2 PMID:7427171

  11. Morningness-eveningness is not associated with academic performance in the afternoon school shift: Preliminary findings. (United States)

    Arrona-Palacios, Arturo; Díaz-Morales, Juan F


    The effect of morningness-eveningness, sleep habits, and intelligence on academic performance has been studied in a fixed morning school shift. However, no studies have analysed these variables in an afternoon school shift and tested whether morningness-eveningness is related to academic performance beyond sleep habits and intelligence effects. The psychometric properties of the Morningness-Eveningness Scale for Children (MESC) were analysed. Additionally, academic performance, sex, intelligence, sleep habits, and morningness-eveningness relationship in a morning and afternoon school shift were compared. The sample consisted of 400 students at a secondary public school in Reynosa, Tamaulipas, in north-eastern Mexico (195 boys and 205 girls; mean ± SD: 13.85 ± 0.70 years old) attending a double-shift school system: 200 from the morning shift (99 boys and 101 girls) and 200 from the afternoon shift (96 boys and 104 girls). The students completed the MESC as a measure of morningness-eveningness, a sleep habits survey, a test of academic performance, and the inductive reasoning subtest (R) of the Primary Mental Abilities battery. Adolescents in the two school shifts did not differ in academic performance and intelligence. In the afternoon shift, adolescents slept longer, reported less sleep deficit and social jet lag, and were more oriented to eveningness than adolescents in the morning shift. Sex (girls), sleep length, inductive reasoning, and morningness were associated with academic performance in the morning shift but only sex and intelligence in the afternoon shift. The role of morningness-eveningness in academic performance in the afternoon shift is examined. © 2017 The British Psychological Society.

  13. Characterizing Fractures Across the Astronaut Corps: Preliminary Findings from Population-Level Analysis (United States)

    Rossi, Meredith M.; Charvat, Jacqueline; Sibonga, Jean; Sieker, Jeremy


    Despite evidence of bone loss during spaceflight and operational countermeasures to mitigate this loss, the subsequent risk of fracture among astronauts is not known. The physiologic process of diminished bone density and bone recovery during or following spaceflight is multifactorial. Such factors as age, sex, fracture history, and others may combine to increase fracture risk among astronauts. As part of the 2016 Bone Research and Clinical Advisory Panel (RCAP), the authors analyzed data collected on 338 NASA astronauts to describe the demographics, bone-relevant characteristics, and fracture history of the astronaut population. The majority of the population are male (n=286, 84.6%), have flown at least one mission (n=306, 90.5%), and were between the ages of 30 and 49 at first mission (n=296, 96.7% of those with at least one mission). Of the 338 astronauts, 241 (71.3%) experienced a fracture over the course of their lifetime. One hundred and five (43.5%) of these 241 astronauts only experienced a fracture prior to being selected into the Astronaut Corps, whereas 53 (22.0%) only experienced a fracture after selection as an astronaut. An additional 80 astronauts (33.2%) had both pre- and post-selection fractures. The remaining 3 astronauts had a fracture of unknown date, which could not be categorized as pre- or post-selection. Among the 133 astronauts with at least one post-selection fracture, males comprised 90.2% (n=120) compared to 84.5% of the entire Corps, and females accounted for 9.8% (n=13) compared to 15.4% of the Corps. Ninety-seven of the 133 astronauts with post-selection fractures (72.9%) had one fracture event, 22 (16.5%) had two fractures, and 14 (10.5%) had three or more fractures. Some astronauts with multiple fractures suffered these in a single event, such as an automobile accident. The 133 astronauts with a post-selection fracture accounted for a total of 188 fracture events. One hundred and four (78.2%) of astronauts with post-selection fractures experienced those fractures following their first mission (mean 12.7 +/- 11.1 years following first mission; range 14.0 days - 50.6 years). Additional analyses are ongoing and include examination of fracture history, skeletal site, mechanism, and type of fracture, age at time of fracture, time from spaceflight to fracture, as well as multivariable analysis comparing fracture events to non-events. The results of such analyses may reveal trends in risk factors for fracture among the astronaut corps that have yet to be systematically described through a corps-wide approach.

  14. 4K Video-Laryngoscopy and Video-Stroboscopy: Preliminary Findings. (United States)

    Woo, Peak


    4K video is a new format. At 3840 × 2160 resolution, it has 4 times the resolution of standard 1080 high definition (HD) video. Magnification can be done without loss of resolution. This study uses 4K video for video-stroboscopy. Forty-six patients were examined by conventional video-stroboscopy (digital 3 chip CCD) and compared with 4K video-stroboscopy. The video was recorded on a Blackmagic 4K cinema production camera in CinemaDNG RAW format. The video was played back on a 4K monitor and compared to standard video. Pathological conditions included: polyps, scar, cysts, cancer, sulcus, and nodules. Successful 4K video recordings were achieved in all subjects using a 70° rigid endoscope. The camera system is bulky. The examination is performed similarly to standard video-stroboscopy. Playback requires a 4K monitor. As expected, the images were far clearer in detail than standard video. Stroboscopy video using the 4K camera was consistently able to show more detail. Two patients had diagnosis change after 4K viewing. 4K video is an exciting new technology that can be applied to laryngoscopy. It allows for cinematic 4K quality recordings. Both continuous and stroboscopic light can be used for visualization. Its clinical utility is feasible, but usefulness must be proven. © The Author(s) 2015.

  15. Relation of Habitual Chocolate Consumption to Arterial Stiffness in a Community-Based Sample: Preliminary Findings (United States)

    Crichton, Georgina E.; Elias, Merrill F.; Alkerwi, Ala'a; Stranges, Saverio; Abhayaratna, Walter P.


    Background The consumption of chocolate and cocoa has established cardiovascular benefits. Less is known about the effects of chocolate on arterial stiffness, a marker of subclinical cardiovascular disease. The aim of this study was to investigate whether chocolate intakes are independently associated with pulse wave velocity (PWV), after adjustment for cardiovascular, lifestyle and dietary factors. Methods Prospective analyses were undertaken on 508 community-dwelling participants (mean age 61 years, 60% women) from the Maine-Syracuse Longitudinal Study (MSLS). Habitual chocolate intakes, measured using a food frequency questionnaire, were related to PWV, measured approximately 5 years later. Results Chocolate intake was significantly associated with PWV in a non-linear fashion with the highest levels of PWV in those who never or rarely ate chocolate and lowest levels in those who consumed chocolate once a week. This pattern of results remained and was not attenuated after multivariate adjustment for diabetes, cardiovascular risk factors and dietary variables (p = 0.002). Conclusions Weekly chocolate intake may be of benefit to arterial stiffness. Further studies are needed to explore the underlying mechanisms that may mediate the observed effects of habitual chocolate consumption on arterial stiffness. PMID:27493901

  16. Malaria mosquito control using edible fish in western Kenya: preliminary findings of a controlled study

    Directory of Open Access Journals (Sweden)

    Omlin Francois X


    Full Text Available Abstract Background Biological control methods are once again being given much research focus for malaria vector control. This is largely due to the emerging threat of strong resistance to pesticides. Larvivorous fish have been used for over 100 years in mosquito control and many species have proved effective. In the western Kenyan highlands the larvivorous fish Oreochromis niloticus L. (Perciformes: Cichlidae (formerly Tilapia nilotica is commonly farmed and eaten but has not been previously tested in the field for malaria mosquito control. Methods This fish was introduced into abandoned fishponds at an altitude of 1,880 m and the effect measured over six months on the numbers of mosquito immatures. For comparison an untreated control pond was used. During this time, all ponds were regularly cleared of emergent vegetation and fish re-stocking was not needed. Significant autocorrelation was removed from the time series data, and t-tests were used to investigate within a pond and within a mosquito type any differences before and after the introduction of O. niloticus. Mulla's formula was also used on the raw data to calculate the percentage reduction of the mosquito larvae. Results After O. niloticus introduction, mosquito densities immediately dropped in the treated ponds but increased in the control pond. This increase was apparently due to climatic factors. Mulla's formula was applied which corrects for that natural tendency to increase. The results showed that after 15 weeks the fish caused a more than 94% reduction in both Anopheles gambiae s.l. and Anopheles funestus (Diptera: Culicidae in the treated ponds, and more than 75% reduction in culicine mosquitoes. There was a highly significantly reduction in A. gambiae s.l. numbers when compared to pre-treatment levels. Conclusion This study reports the first field trial data on O. niloticus for malaria mosquito control and shows that this species, already a popular food fish in western Kenya, is an apparently sustainable mosquito control tool which also offers a source of protein and income to people in rural areas. There should be no problem with acceptance of this malaria control method since the local communities already farm this fish species.

  20. Construction ages of the Upton Stone Chamber: Preliminary findings and suggestions for future luminescence research (United States)

    Mahan, Shannon; Martin, Frederick; Taylor, Cathy


    The Upton Chamber in Massachusetts, an earth-covered stone structure 3.4 meters (m) in diameter, with a corbelled stone dome, and a 4.3 m long entrance passageway, is studied with the aim of determining whether optically stimulated luminescence (OSL) dating methods can be used to establish the approximate construction date of the entranceway. Three samples, taken from soil behind the lowest stones in the wall of the entrance passageway, returned OSL ages between 385 and 660 years ago (or from 1625 A.D. to 1350 A.D.; using the year 2011 as the 0 year). One sample, taken below the bottom of the artifact layers in an archeological test pit in front of the chamber entrance, returned OSL ages between 650 and 880 years ago. A modern sample collected from a nearby fluvial channel returned an age between 55 and 175 years. The Upton Chamber OSL sampling results are challenging to interpret because there are mixtures in the samples of both younger and older grains that likely result from human modification, root or soil processes, animal bioturbation (i.e. ants and worms), and/or partial bleaching. The ages were determined using the lowest component of the finite mixture model as applied to a distribution of quartz grains. Further research may enable us to determine whether older components are of anthropomorphic or geological origin.

  1. Preliminary Findings of the Photovoltaic Cell Calibration Experiment on Pathfinder Flight 95-3 (United States)

    Vargas-Aburto, Carlos


    The objective of the photovoltaic (PV) cell calibration experiment for Pathfinder was to develop an experiment compatible with an ultralight UAV to predict the performance of PV cells at AM0, the solar spectrum in space, using the Langley plot technique. The Langley plot is a valuable technique for this purpose and requires accurate measurements of air mass (pressure), cell temperature, solar irradiance, and current-voltage(IV) characteristics with the cells directed normal to the direct ray of the sun. Pathfinder's mission objective (95-3) of 65,000 ft. maximum altitude, is ideal for performing the Langley plot measurements. Miniaturization of electronic data acquisition equipment enabled the design and construction of an accurate and light weight measurement system that meets Pathfinder's low payload weight requirements.

  6. Preliminary Findings of the South Africa Power System Capacity Expansion and Operational Modelling Study

    Energy Technology Data Exchange (ETDEWEB)

    Reber, Timothy J [National Renewable Energy Laboratory (NREL), Golden, CO (United States); Chartan, Erol Kevin [National Renewable Energy Laboratory (NREL), Golden, CO (United States); Brinkman, Gregory L [National Renewable Energy Laboratory (NREL), Golden, CO (United States)


    Wind and solar power contract prices have recently become cheaper than many conventional new-build alternatives in South Africa and trends suggest a continued increase in the share of variable renewable energy (vRE) on South Africa's power system with coal technology seeing the greatest reduction in capacity, see 'Figure 6: Percentage share by Installed Capacity (MW)' in [1]. Hence it is essential to perform a state-of-the-art grid integration study examining the effects of these high penetrations of vRE on South Africa's power system. Under the 21st Century Power Partnership (21CPP), funded by the U.S. Department of Energy, the National Renewable Energy Laboratory (NREL) has significantly augmented existing models of the South African power system to investigate future vRE scenarios. NREL, in collaboration with Eskom's Planning Department, further developed, tested and ran a combined capacity expansion and operational model of the South African power system including spatially disaggregated detail and geographical representation of system resources. New software to visualize and interpret modelling outputs has been developed, and scenario analysis of stepwise vRE build targets reveals new insight into associated planning and operational impacts and costs. The model, built using PLEXOS, is split into two components, firstly a capacity expansion model and secondly a unit commitment and economic dispatch model. The capacity expansion model optimizes new generation decisions to achieve the lowest cost, with a full understanding of capital cost and an approximated understanding of operational costs. The operational model has a greater set of detailed operational constraints and is run at daily resolutions. Both are run from 2017 through 2050. This investigation suggests that running both models in tandem may be the most effective means to plan the least cost South African power system as build plans seen to be more expensive than optimal by the capacity expansion model can produce greater operational cost savings seen only in the operational model.

  9. Internet-Based Self-Help Intervention for ICD-11 Adjustment Disorder: Preliminary Findings. (United States)

    Eimontas, Jonas; Rimsaite, Zivile; Gegieckaite, Goda; Zelviene, Paulina; Kazlauskas, Evaldas


    Adjustment disorder is one of the most diagnosed mental disorders. However, there is a lack of studies of specialized internet-based psychosocial interventions for adjustment disorder. We aimed to analyze the outcomes of an internet-based unguided self-help psychosocial intervention BADI for adjustment disorder in a two armed randomized controlled trial with a waiting list control group. In total 284 adult participants were randomized in this study. We measured adjustment disorder as a primary outcome, and psychological well-being as a secondary outcome at pre-intervention (T1) and one month after the intervention (T2). We found medium effect size of the intervention for the completer sample on adjustment disorder symptoms. Intervention was effective for those participants who used it at least one time in 30-day period. Our results revealed the potential of unguided internet-based self-help intervention for adjustment disorder. However, high dropout rates in the study limits the generalization of the outcomes of the intervention only to completers.

  10. The impact of methamphetamine use on subjective well-being in an Internet survey: preliminary findings. (United States)

    Looby, Alison; Earleywine, Mitch


    Methamphetamine is one of the most widely used stimulants worldwide. Common reasons for use of the drug include efforts to improve or enhance one's life and to uplift one's mood. Nevertheless, acute effects of the drug lead to temporary improvements in mood followed by negative affect. The purpose of the present study was to expand on the current literature and examine other aspects of mood and satisfaction with life in methamphetamine users. Over 6000 adults completed an Internet survey and reported on depression, apathy, satisfaction with life, happiness, and subjective well-being, in addition to measures of methamphetamine use. We compared those who had used methamphetamine at least once within the past year (N = 610) to those who had never used (N = 6063). Methamphetamine use accounted for significant variance in depression, apathy, satisfaction with life, happiness, and subjective well-being even when alcohol and other drugs served as covariates. Methamphetamine use may decrease one's subjective well-being instead of enhancing it, which is contradictory to the perceptions of many users. Increasing awareness about methamphetamine's negative impact on mood and life satisfaction might help decrease prevalence of the drug's use and associated troubles.

    African Journals Online (AJOL)

    The volume of stimulated saliva was determined and divided by the duration of saliva collection. The pH was measured directly using a pH meter. The buffering capacity was determined using a quantitative method which involved the addition of 10 μl HCl. Up to a total of 160 μL was titrated up to obtain a pH titration curve.

  12. Study addiction--a new area of psychological study: conceptualization, assessment, and preliminary empirical findings. (United States)

    Atroszko, Paweł A; Andreassen, Cecilie Schou; Griffiths, Mark D; Pallesen, Ståle


    Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to 'study addiction'. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. The Bergen Study Addiction Scale (BStAS) was tested - reflecting seven core addiction symptoms (salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) - related to studying. The scale was administered via a cross-sectional survey distributed to Norwegian (n = 218) and Polish (n = 993) students with additional questions concerning demographic variables, study-related variables, health, and personality. A one-factor solution had acceptable fit with the data in both samples and the scale demonstrated good reliability. Scores on BStAS converged with scores on learning engagement. Study addiction (BStAS) was significantly related to specific aspects of studying (longer learning time, lower academic performance), personality traits (higher neuroticism and conscientiousness, lower extroversion), and negative health-related factors (impaired general health, decreased quality of life and sleep quality, higher perceived stress). It is concluded that BStAS has good psychometric properties, making it a promising tool in the assessment of study addiction. Study addiction is related in predictable ways to personality and health variables, as predicted from contemporary workaholism theory and research.

  13. Preliminary findings on identification of mycorrhizal fungi from diverse orchids in the Central Highlands of Madagascar. (United States)

    Yokoya, Kazutomo; Zettler, Lawrence W; Kendon, Jonathan P; Bidartondo, Martin I; Stice, Andrew L; Skarha, Shannon; Corey, Laura L; Knight, Audrey C; Sarasan, Viswambharan


    The Orchid flora of Madagascar is one of the most diverse with nearly 1000 orchid taxa, of which about 90% are endemic to this biodiversity hotspot. The Itremo Massif in the Central Highlands of Madagascar with a Highland Subtropical climate range encompasses montane grassland, igneous and metamorphic rock outcrops, and gallery and tapia forests. Our study focused on identifying culturable mycorrhizae from epiphytic, lithophytic, and terrestrial orchid taxa to understand their diversity and density in a spatial matrix that is within the protected areas. We have collected both juvenile and mature roots from 41 orchid taxa for isolating their orchid mycorrhizal fungi (OMF), and to culture, identify, and store in liquid nitrogen for future studies. Twelve operational taxonomic units (OTUs), of three known orchid mycorrhizal genera, were recognized by analysis of internal transcribed spacer (ITS) sequences of 85 isolates, and, by comparing with GenBank database entries, each OTU was shown to have closely related fungi that were also found as orchid associates. Orchid and fungal diversity were greater in gallery forests and open grasslands, which is very significant for future studies and orchid conservation. As far as we know, this is the first ever report of detailed identification of mycorrhizal fungi from Madagascar. This study will help start to develop a programme for identifying fungal symbionts from this unique biodiversity hotspot, which is undergoing rapid ecosystem damage and species loss. The diversity of culturable fungal associates, their density, and distribution within the Itremo orchid hotspot areas will be discussed.

    The frequency of nonvalvular atrial fibrillation is increasing in sub-Saharan Africa, particularly as a consequence of population aging and the high prevalence of hypertension. The aim of this descriptive study was to determine the cost of management of this disease in the cardiology department at University Hospital of Brazzaville. The study included 50 patients aged 67.3 ± 12.8 years (range: 34 to 88 years). Among them, 21 (42%) were unemployed, and 49 (98%) had no health insurance. Their average monthly salary was 152.8 ± 149 € (range: 0 to 686 €). The mean total cost of care was 442.4 ± 109.8 € (range: 146.6 to 646.2 €). The average monthly salary was higher than the average cost of drugs (P hospital hospitality (P <0.0001). But the overall cost of care was substantially higher than the patients' mean salary (p <0.0001). This study illustrates the increasing healthcare costs related to the growing burden of cardiovascular disease in sub-Saharan Africa.

  16. Does spasticity result from hyperactive stretch reflexes? Preliminary findings from a stretch reflex characterization study. (United States)

    Salazar-Torres, J De J; Pandyan, A D; Price, C I M; Davidson, R I; Barnes, M P; Johnson, G R


    To characterize the stretch reflex response of the biceps brachii in stroke patients with elbow spasticity (prior to or within 15 min of treatment with botulinum toxin) and non-impaired volunteers with the aim of quantifying the stretch reflex excitability and observe the differences between the groups. A cross-sectional study. Stretch reflexes from the biceps brachii were elicited following a controlled elbow extension. The amplitude, latency, rise time and duration, calculated from surface EMG recordings from the biceps brachii, were used to characterize the stretch reflex response. Seventeen non-impaired and 14 stroke patients participated. The amplitude was significantly lower in stroke patients than in non-impaired volunteers (p0.10). Reduction in the amplitude in stroke patients was unexpected suggesting the stretch reflex is not necessarily hyper-excitable in people with clinically diagnosed spasticity. Latency differences suggest decreased presynaptic inhibition and/or increased motor neurone excitability can occur following a stroke. However, carry over effects from previous botulinum toxin treatment may have confounded amplitude measurements. Further work evaluating the excitability of the stretch reflex independent of Botulinum toxin and its contribution to resistance to passive stretching is being conducted.

    Rosales Delgado, J A; González-Sicilia Cotter, E; Aedo Ocaña, O


    Laparoscopy was performed on patients with dysmenorrhea, sterility and pelvic pain in order to evaluate the prevalence of endometriosis in our environment therefore considering the population of female beneficiary patients of reproductive age of the ISSSTE hospital in the city of Veracruz, Ver. in México. The percentages of endometriosis were similar to the reports published in the international journals with the exception of the dysmenorrhea where our results were higher. In all the cases the same variables were analyzed; age, active sexual life (V.S.A.), birth control method, menarche (men), menstrual cycle, childbirths and abortions, as well as other laparoscopic detections. Each of the endometriosis cases were classified according to the revised American Fertility Society classification of 1985 (R.A.F.S.) for endometriosis.

    Full Text Available Objective – To explore and analyze, against three theoretical frameworks of information behaviours, how people with HIV/AIDS, their friends, and their family living in rural communities find information on HIV/AIDS.Design – Qualitative, individual, in‐depth, semi‐structured interviews.Setting – Two rural regions in Ontario, Canada.Subjects – Sixteen participants; 10 people with HIV/AIDS (PHAs and 6 family members or friends.Methods – Participants were recruited through health care providers, social service agencies and through snowball sampling. Semi‐structure interviews were conducted focusing on participants’ experience with HIV/AIDS, how they find and use information on HIV/AIDS, networks for information exchange and the effect of technology on information exchange. Interviews were taped, transcribed, analyzed qualitatively using NVivo software. Results were compared to three theoretical frameworks for information behaviour: 1. purposeful information seeking (i.e., the idea that people purposefully seek information to bridge perceived knowledge gaps; 2. non‐purposeful or incidental information acquisition (i.e., the idea that people absorb information from going about daily activities; and 3. information gate keeping (i.e., the concept of private individuals who act as community links and filters for information gathering and dissemination.Main Results – Consistent with the theories:•PHAs prefer to receive information from people they have a personal relationship with, particularly their physician and especially other PHAs.•PHAs’ friends and families rely on their friends and family for information, and are particularly reliant upon the PHA in their lives.•Fear of stigma and discrimination cause some to avoid seeking information or to prefer certain sources of information, such as healthcare providers, who are bound by codes of professional conduct.•Emotional support is important in information provision and

  20. Preliminary investigation of an active PLZT lens (United States)

    Peters, Bruce R.; Reardon, Patrick J.; Wong, K. J.


    The design analysis and preliminary testing of a prototype AFOCL is described. The AFOCL is an active optical component composed of solid state lead lanthanum-modified zirconate titanate (PLZT) ferroelectric ceramic with patterned indium tin oxide (ITO) transparent surface electrodes that modulate the refractive index of the PLZT to function as an electro- optic lens. The AFOCL was developed to perform optical re- alignment and wavefront correction to enhance the performance of Ultra-Lightweight Structures and Space Observatories. The AFOCL would be an active optical component within a larger optical system. Information from a wavefront sensor would be processed to provide input to the AFOCL to drive the sense4d wavefront tot he desired shape and location. While offering variable and rapid focusing capability similar to liquid crystal based spatial light modulators, the AFOCL offers some potential advantages because it is a solid-stat, stationary, low-mass, rugged, and thin optical element that can produce wavefront quality comparable to the solid refractive lens it replaces. The AFOCL acts as a positive or negative lens by producing a parabolic phase-shift in the PLZT material through the application of a controlled voltage potential across the ITO electrodes. To demonstrate the technology, a 4 mm diameter lens was fabricated to produce 5-waves of optical power operating at 2.051 micrometers wavelength. Optical metrology was performed on the device to measure focal length, optical quality, and efficiency for a variety of test configurations. Preliminary data was analyzed and compared to idealized performance available from computer-based models of the AFOCL.

  1. Topaz II preliminary safety assessment (United States)

    Marshall, Albert C.; Standley, Vaughn; Voss, Susan S.; Haskin, Eric


    The Strategic Defense Initiative Organization (SDIO) decided to investigate the possibility of launching a Russian Topaz II space nuclear power system. A preliminary safety assessment was conducted to determine whether or not a space mission could be conducted safely and within budget constraints. As part of this assessment, a safety policy and safety functional requirements were developed to guide both the safety assessment and future Topaz II activities. A review of the Russian flight safety program was conducted and documented. Our preliminary safety assessment included a top level event tree, neutronic analysis of normal and accident configurations, an evaluation of temperature coefficients of reactivity, a reentry and disposal analysis, and analysis of postulated launch abort impact accidents, and an analysis of postulated propellant fire and explosion accidents. Based on the assessment, it appears that it will be possible to safely launch the Topaz II system in the U.S. with some possible system modifications. The principal system modifications will probably include design changes to preclude water flooded criticality and to assure intact reentry.

  2. Guidance for performing preliminary assessments under CERCLA

    Energy Technology Data Exchange (ETDEWEB)



    EPA headquarters and a national site assessment workgroup produced this guidance for Regional, State, and contractor staff who manage or perform preliminary assessments (PAs). EPA has focused this guidance on the types of sites and site conditions most commonly encountered. The PA approach described in this guidance is generally applicable to a wide variety of sites. However, because of the variability among sites, the amount of information available, and the level of investigative effort required, it is not possible to provide guidance that is equally applicable to all sites. PA investigators should recognize this and be aware that variation from this guidance may be necessary for some sites, particularly for PAs performed at Federal facilities, PAs conducted under EPA`s Environmental Priorities Initiative (EPI), and PAs at sites that have previously been extensively investigated by EPA or others. The purpose of this guidance is to provide instructions for conducting a PA and reporting results. This guidance discusses the information required to evaluate a site and how to obtain it, how to score a site, and reporting requirements. This document also provides guidelines and instruction on PA evaluation, scoring, and the use of standard PA scoresheets. The overall goal of this guidance is to assist PA investigators in conducting high-quality assessments that result in correct site screening or further action recommendations on a nationally consistent basis.

  3. Residential immersive life skills programs for youth with disabilities: service providers' perceptions of experiential benefits and key program features. (United States)

    King, Gillian; McPherson, Amy; Kingsnorth, Shauna; Stewart, Debra; Glencross-Eimantas, Tanya; Gorter, Jan Willem; Jones-Galley, Kimberlea; Morrison, Andrea; Isihi, Ana Maria


    The objective was to determine service providers' perceptions of the experiential benefits of residential immersive life skills (RILS) programs for youth with disabilities, along with important program features. Thirty-seven service providers from three RILS programs took part in qualitative interviews. Themes were derived using a phenomenological approach. There were perceived benefits for youth, and also for parents and service providers. Study themes concerned the process of youth empowerment, life-changing experiences for youth and parents, and changed service provider views affecting practice. Youth changes were attributed to the residential group format and afforded opportunities, which included being away from home, navigating public transportation, directing attendant services, and sharing intense learning and social experiences with peers. Youth were seen to experience important personal changes in life skills, self-confidence, self-understandings, and self-advocacy. Perceived benefits for parents included realizations concerning their child's abilities and new hope for the future. Service providers indicated changes in their knowledge, perspectives, and approach to practice. The findings suggest that life skills programs should be intentionally designed to provide challenging experiential opportunities that motivate youth to engage in new life directions by providing new insights, self-realizations, and positive yet realistic views of the future. Service providers indicated the importance of challenging, real-world experiential opportunities that provide youth with disabilities with new insights, self-realizations, and positive yet realistic views of the future. Important experiential opportunities for youth included being away from home, navigating public transportation, directing attendant care, and sharing intense learning and social experiences with peers. The findings provide preliminary qualitative evidence that life skills programs should be

  12. Preliminary decommissioning study reports. Volume 11, Old Hydrofracture Facility

    Energy Technology Data Exchange (ETDEWEB)

    Reed, W.R.


    The Old Hydrofracture Facility (OHF) is one of approximately 76 facilities currently managed by the Oak Ridge National Laboratory (ORNL) Surplus Facilities Management Program (SFMP). This program, as part of the Department of Energy (DOE) national SFMP, is responsible for the maintenance and surveillance and the final decommissioning of radioactively contaminated surplus ORNL facilities. A long-range planning effort is being conducted that will outline the scope and objectives of the ORNL program and establish decommissioning priorities based on health and safety concerns, budget constraints, and other progammatic constraints. IN support of this SFMP planning activity, preliminary engineering assessments are being conducted for each of the ORNL surplus facilities currently managed under the program. These efforts are designed to: (1) provide an initial assessment of the potential decommissioning alternatives, (2) choose a preferred alternative and provide a justification for that choice, and (3) provide a preliminary description of the decommissioning plan, including cost and schedule estimates. This report presents the results of the preliminary analysis for the OHF.

  13. Galaxy collisions: A preliminary study

    Energy Technology Data Exchange (ETDEWEB)

    Miller, R.H.; Smith, B.F.


    Collisions of spherical galaxies were studied in a series of numerical experiments to see what happens when galaxies collide. Each experiment starts with two model galaxies, each consisting of 50,000 stars, moving toward each other along a specified orbit. Th series of experiments provides a systematic sampling of the parameter space spanned by the initial orbital energy and the initial angular momentum. Deeply penetrating collisions are emphasized. The collisions reported here scale to relative velocities as great as 500 km s/sup -1/, well into the range for collisions within clusters of galaxies. We find: (1) The galaxies contract momentarily to about half their original sizes shortly after close passage. This means that (a) the galaxies have ample time to respond dynamically during close passage; (b) energy first transfers into coherent mass flows within each galaxy; (c) in turn, (a) means that the impulsive and restricted three-body approximations, in which the response is ignored, are not valid for collisions of 1000 km s/sup -1/ or less. (2) The initial galaxies blend into a single dynamical system while they are near each other. This means that concepts such as energy transfer from orbital motion to internal degrees of freedom are not well defined until long after close approach, when two density maxima are well separated and each has settled down to a reasonably steady state.

  14. Virtual laryngoscopy-preliminary experience

    Byrne, A.T. [Departments of Radiology, Adelaide and Meath Hospital, Dublin 24 (Ireland); Walshe, P. [Departments of Otolaryngology, Adelaide and Meath Hospital, Dublin 24 (Ireland); McShane, D. [Departments of Otolaryngology, Adelaide and Meath Hospital, Dublin 24 (Ireland); Hamilton, S. [Departments of Radiology, Adelaide and Meath Hospital, Dublin 24 (Ireland)]. E-mail:


    Purpose: Computed tomographic virtual laryngoscopy is a non-invasive radiological technique that allows visualisation of intra-luminal surfaces by three-dimensional reconstruction of air/soft tissue interfaces. It is particularly useful when the patient cannot tolerate clinical examination, when infection, neoplasm or congenital defects compromise the lumen and for assessment of the sub-glottic region. We have performed virtual laryngoscopy on patients referred because of upper airway symptoms, and compared the findings with those at conventional laryngoscopy. Materials and methods: Axial scans were obtained using a Toshiba Xpress helical scanner. Virtual laryngoscopy was then performed on a workstation using Toshiba 'Fly-thru' software and was completed within 5 min. Results: Pathology included vocal cord nodules, laryngeal cysts, Reinke's oedema, laryngeal neoplasms and leukoplakia. Conclusions: Virtual laryngoscopy displays anatomical detail comparable to conventional endoscopy. Impassable obstructions are no hindrance and all viewing directions are possible. It is especially useful for providing views of the larynx from below.

  15. The antler finds at Bilzingsleben, excavations 1969-1993

    Full Text Available 2820 antler remains from the Lower Palaeolithic site of Bilzingsleben, Thuringia, Germany (excavations 1969-1993 were the subject of detailed investigations. The two major goals were: 1.the consideration of taphonomic aspects 2.the critical evaluation of suggestions about artificial modifications to the antler material A detailed morphological description of the antler material provided the basis for the investigation. A prerequisite was the transfer of provenance data onto an x-y coordinate grid. Taphonomic aspects considered in this work include the relative frequencies of antler elements, estimates regarding the minimum number of individual deer, their age structure and seasonality, and, insofar as the condition of the antlers allowed, the classification of surface preservation, size classes and spatial distribution of the finds. The assemblage of antler finds, the majority of which seems to have come from red deer, is dominated by small fragments, mostly of tines. About one quarter of the finds are larger than 150 mm. Lower beams are more abundant than upper beams (e.g. crowns. Detailed counting, substantiated by systematic reconstruction, shows that in general the antlers are incomplete. After reconstruction of unshed antlers, it was possible to assess the minimum number of heads at 150 animals. Preliminary counting of postcranial and cranial (non antler cervid material points to about 70 cervids. Intentional accumulation of antlers by hominids can only be accepted as the reason for these disproportionate figures if other site formation processes can be ruled out. In fact, the correlation between sediment thickness and maximum antler densities, at least for finds smaller than 120mm, suggests that fluvial accumulation has to be taken into account as a probable element of the site formation history. Further, the mixture of unifacially abraded finds together with finds that exhibit bifacial abrasion points to a succession of changing fluvial

  16. The Role of Health Care Provider Goals, Plans, and Physician Orders for Life-Sustaining Treatment (POLST) in Preparing for Conversations About End-of-Life Care. (United States)

    Russell, Jessica


    The Physician Orders for Life-Sustaining Treatment (POLST) is a planning tool representative of an emerging paradigm aimed at facilitating elicitation of patient end-of-life care preferences. This study assessed the impact of the POLST document on provider goals and plans for conversations about end-of-life care treatment options. A 2 (POLST: experimental, control) × 3 (topic of possible patient misunderstanding: cardiopulmonary resuscitation, medical intervention, artificially administered nutrition) experimental design was used to assess goals, plan complexity, and strategies for plan alterations by medical professionals. Findings suggested that the POLST had little impact on plan complexity or reaction time with initial plans. However, preliminary evidence suggested that the utility of the POLST surfaced with provider responses to patient misunderstanding, in which differences in conditions were identified. Significant differences in goals reported as most important in driving conversational engagement emerged. Implications for findings are discussed.

    Dierker, S.


    Following the CD0 approval of the National Synchrotron Light Source II (NSLS-II) during August 2005, Brookhaven National Laboratory prepared a conceptual design for a worldclass user facility for scientific research using synchrotron radiation. DOE SC review of the preliminary baseline in December 2006 led to the subsequent CD1 approval (approval of alternative selection and cost range). This report is the documentation of the preliminary design work for the NSLS-II facility. The preliminary design of the Accelerator Systems (Part 1) was developed mostly based of the Conceptual Design Report, except for the Booster design, which was changed from in-storage-ring tunnel configuration to in external- tunnel configuration. The design of beamlines (Part 2) is based on designs developed by engineering firms in accordance with the specification provided by the Project. The conventional facility design (Part 3) is the Title 1 preliminary design by the AE firm that met the NSLS-II requirements. Last and very important, Part 4 documents the ES&H design and considerations related to this preliminary design. The NSLS-II performance goals are motivated by the recognition that major advances in many important technology problems will require scientific breakthroughs in developing new materials with advanced properties. Achieving this will require the development of new tools that will enable the characterization of the atomic and electronic structure, chemical composition, and magnetic properties of materials, at nanoscale resolution. These tools must be nondestructive, to image and characterize buried structures and interfaces, and they must operate in a wide range of temperatures and harsh environments. The NSLS-II facility will provide ultra high brightness and flux and exceptional beam stability. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility

  18. Mapping Antarctica using Landsat-8 - the preliminary results (United States)

    Cheng, X.; Hui, F.; Qi, X.


    The first Landsat Image Mosaic of Antarctica (LIMA) was released in 2009, which was created by USGS, BAS, and NASA from more than 1,000 Landsat ETM+ scenes. As the first major scientific outcome of the IPY, LIMA supports current scientific polar research, encourages new projects, and helps the general public visualize Antarctica and changes happening to this southernmost environment. As the latest satellite of Landsat mission, the Landsat-8 images the entire Earth every 16 days in an 8-day offset from Landsat-7. Data collected by the instruments onboard the satellite are available to download at no charge within 24 hours of reception. The standard Landsat 8 products provided by the USGS EROS Center consist of quantized and calibrated scaled Digital Numbers (DN) in 16-bit unsigned integer format and can be rescaled to the Top Of Atmosphere (TOA) reflectance and/or radiance. With the support of USGS portal, we searched and downloaded more than 1600 scenes of Level 1 T- Terrain Corrected Landsat 8 image products covering Antarctica from late 2013 to early 2014. These data were converted to planetary radiance for further processing. Since the distribution of clouds in these images are random and much complicated, statistics on the distribution of clouds were performed and then help to decide masking those thicker cloud to keep more useful information left and avoid observation holes. A preliminary result of the Landsat-8 mosaic of Antarctica under the joint efforts of Beijing Normal University, NSIDC and University of Maryland will be released on this AGU fall meeting. Comparison between Landsat 7 and 8 mosaic products will also be done to find the difference or advantage of the two products.
