    Razzaghi, Andrea I.

    1987-01-01

    A method is presented for designing worm gear sets to meet torque multiplication requirements. First, the fundamentals of worm gear design are discussed, covering worm gear set nomenclature, kinematics and proportions, force analysis, and stress analysis. Then, a suggested design method is discussed, explaining how to take a worm gear set application, and specify a complete worm gear set design. The discussions are limited to cylindrical worm gear sets that have a 90 deg shaft angle between the worm and the mating gear.

    The critical design method aims to discuss ways of opening up the (design) brief when planning, designing, building, operating and maintaining the future of the built environment - public as well as private, indoor as well as outdoor. Focusing on "designials" (fundamental forms of design being), the methodology intends to illustrate the fact that objects; including buildings, parks, transportation systems, etc. may directly encroach upon certain "existentials" (fundamental forms of human being) - thus shed light on how a design process is normally conducted, and furthermore, how that affects people's existential well-being.

    1981-09-24

    A magnet set, consisting of 24 coils, has been designed for the TMX Upgrade. Like the coil set designed for the TMX experiment, the coils for TMX Upgrade consist of a central-cell set with a minimum-B plug set on each end. Between the central cell and each end plug, there is a flux bundle recircularizing transition set. Physics considerations require that the TMX Upgrade magnet set be almost twice as long as the TMX magnet set (14 m between the outer mirrors). The central circular coils are the only coils used from TMX. The TMX transition set of two C-coils and an octupole is replaced by a C-coil and an Ioffe coil. The TMX plug composed of a baseball coil and two C-coils is replaced by an Ioffe coil, two C-coils and two circular coils. A comparison between the TMX and TMX Upgrade magnet sets is shown.

    2003-01-01

    Viable strategies are needed to move toward collection of a standardized nursing data set across settings for eventual use in examining nursing effectiveness. One strategy is to introduce potential nurse adopters to subsets of valid setting-specific standardized terms and measures to support adoption and initial implementation. The present study was designed to identify the "most clinically useful" NANDA (North American Nursing Diagnoses Association) diagnoses, NOC (Nursing Outcomes Classifications) outcomes, and NIC (Nursing Intervention Classifications) interventions pertinent to the adult care nurse practitioner setting. Ultimately, clinicians must recognize, however, that they will need to use additional terms and measures outside the subsets to more fully describe the nursing care provided. PMID:12881972

    Deo, Ravi; Benner, Harry; Vincent, Dawson; Olason, Eric; Harrison, Richard

    2010-01-01

    A study was conducted to develop mass efficient composite struts. A closed-form design methodology for composite struts was developed using well established analyses to predict Euler buckling, local wall buckling; compression strength, damage tolerance, and interlaminar shear at geometric gradients. The methodology was coded in a spreadsheet suitable for convenient and rapid sizing of tapered composite struts. This spreadsheet analysis was used to determine the influence of several variables such as material stiffness, strut diameter, and material allowables on strut weight for given loading conditions. The comparison showed that, while the Park Aerospace design method was well suited to preliminary sizing for a conservative design, the closed-form-analyses-based spreadsheet accounts for all possible failure modes and is a good optimum strut design tool. The report concludes with a set of recommendations for future work in analytical design and analysis methodology enhancements.

    Substituted phenols, anilines, pyridines and nitrobenzenes can be classified as polar narcotics. These chemicals differ from non-polar narcotic compounds not only in that they exhibit a 5 to 10 times higher toxicity, but also in their Fish Acute Toxic Syndromes, together suggesting a different mode of action. For 97 polar narcotics, which are not ionized under physiological conditions, 11 physico-chemical and quantum-chemical descriptors were calculated. Using Principal Components Analysis 91% of the total variance could be explained by three Principal Components, which were subsequently used as factors in a Statistical Design. Eleven compounds were selected based on a two-level full factorial design, including three compounds near the center (2{sup 3} + 3). QSARs were developed for both, the design set and a set of 63 polar narcotics for which guppy and/or fathead minnow data were available in the literature. Both QSAR, based on PLS, resulted in good models (R{sup 2} = 0.96 and Q{sup 2} = 0.8{sup 2}; R{sup 2}= 0.86 and Q{sup 2} = 0.83 respectively) and gave similar Pseudo Regression Coefficients. In addition the model based on the designed chemicals was able to predict the toxicity of the 63 compounds (R{sup 2} = 0.85). These results show that these 11 chemicals are a well-balanced set for further studies of polar narcosis.

  11. Boosting Set Constraint Propagation for Network Design

    NASA Astrophysics Data System (ADS)

    Yip, Justin; van Hentenryck, Pascal; Gervet, Carmen

    This paper reconsiders the deployment of synchronous optical networks (SONET), an optimization problem naturally expressed in terms of set variables. Earlier approaches, using either MIP or CP technologies, focused on symmetry breaking, including the use of SBDS, and the design of effective branching strategies. This paper advocates an orthogonal approach and argues that the thrashing behavior experienced in earlier attempts is primarily due to a lack of pruning. It studies how to improve domain filtering by taking a more global view of the application and imposing redundant global constraints. The technical results include novel hardness results, propagation algorithms for global constraints, and inference rules. The paper also evaluates the contributions experimentally by presenting a novel model with static symmetric-breaking constraints and a static variable ordering which is many orders of magnitude faster than existing approaches.

  12. Design considerations for adult patient education.

    PubMed

    Walsh, P L

    1982-01-01

    A variety of factors require attention in the design of patient education programs for adults. Andragogy, the art and science of helping adults learn, describes certain conditions of learning that are more conducive to growth and development for adults and prescribes practices in the learning-teaching transaction to meet them. Stigma, a special discrepancy between virtual and actual social identity, reduces a patient's self-esteem and fosters a feeling of dependence on others for care. Anxiety related to diagnosis and illness creates a situation in which patients cannot productively learn. The stages in acceptance of diagnosis provide a roadmap for understanding a patient's feelings/psychological processes and insight into opportunities to intervene with patient education. The specific disease a patient has effects his ability to learn. Each of these factors is considered with implications described for designing and implementing patient education activities for adults. PMID:10258421

    Objective To assess the barriers and facilitators to using African American churches as sites for implementation of evidence-based HIV interventions among young African American women. Design Mixed methods cross-sectional design. Setting African American churches in Philadelphia, PA. Participants 142 African American pastors, church leaders, and young adult women ages 18 to 25. Methods Mixed methods convergent parallel design. Results The majority of young adult women reported engaging in high-risk HIV-related behaviors. Although church leaders reported willingness to implement HIV risk-reduction interventions, they were unsure of how to initiate this process. Key facilitators to the implementation of evidence-based interventions included the perception of the leadership and church members that HIV interventions were needed and that the church was a promising venue for them. A primary barrier to implementation in this setting is the perception that discussions of sexuality should be private. Conclusion Implementation of evidence-based HIV interventions for young adult African American women in church settings is feasible and needed. Building a level of comfort in discussing matters of sexuality and adapting existing evidence-based interventions to meet the needs of young women in church settings is a viable approach for successful implementation.

  14. Adults' Learning about Science in Free-choice Settings

    NASA Astrophysics Data System (ADS)

    Rennie, Léonie J.; Williams, Gina F.

    2006-06-01

    This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science-related experiences in free-choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and its communication by scientists. The three studies involved samples of visitors to an interactive science centre, visitors to a traditional natural history museum, and attendees at a series of public lectures, each given by an expert scientist in human genetics. Pretest and post-test data collected by parallel questionnaires indicated that, despite the different nature of their experience in the three different settings, participants became more positive about the value of science and the work done by scientists and their ability to communicate with the public. At all venues, however, participants became less scientific in their thinking about the nature of scientific knowledge, becoming more likely to believe it to be infallible. The consistency of these findings was surprising, and participants’ changed views about the nature of scientific knowledge were unexpected. Possible explanations for theses outcomes were suggested in terms of participants’ reasons for attending the venue, the nature of their engagement, and the non-controversial ways in which the exhibitions and lectures were structured. The findings suggest that the educational role of free-choice settings should be considered carefully, particularly with regard to the representation of science.

    2011-01-01

    SYNOPSIS Despite the benefits of treatment for late-life depression, we are faced with the challenges of underutilization of mental health services by older adults and non-adherence to offered interventions. This paper describes psychosocial and interactional barriers and facilitators of treatment engagement among depressed older adults served by community health care settings. We describe the need to engage older adults in treatment using interventions that: 1. target psychological barriers such as stigma and other negative beliefs about depression and its treatment; and 2. increase individuals’ involvement in the treatment decision-making process. We then present personalized treatment engagement interventions that our group has designed for a variety of community settings. PMID:21536170

    2012-01-01

    The global population is aging. In many industrial countries, almost one in five people are over age 65. As people age, gradual changes ensue in vision, hearing, balance, coordination, and memory. Products, communication materials, and the physical environment must be thoughtfully designed to meet the needs of people of all ages. This article summarizes normal changes in sensory function, mobility, balance, memory, and attention that occur with age. It presents practical guidelines that allow design professionals to accommodate these changes and better meet the needs of older adults. Designing for older adults is inclusive design: it accommodates a range of physical and cognitive abilities and promotes simplicity, flexibility, and ease of use for people of any age. PMID:22980147

  17. Opening clinical encounters in an adult musculoskeletal setting.

    2014-08-01

    Effective communication between healthcare professionals and their patients is crucial for successful consultations, and can profoundly affect patients' adherence to treatment. Despite this evidence, communication within the physiotherapy profession is still underexplored, in particular, how 'best' to open clinical encounters. This study explores the issue by seeking the preferences of physiotherapists for opening encounters in the adult musculoskeletal outpatient setting. Initially, 42 consultations and 17 first follow-up encounters were observed between qualified physiotherapists and patients with back pain. These encounters were audio-recorded, analysed and used to develop a questionnaire to determine clinicians' preferences for opening encounters. From these findings, a synopsis of the questionnaire was posted on the four most-relevant professional networks of the national, interactive Chartered Society of Physiotherapy (iCSP) website, to canvass opinion more widely. Among the 43 physiotherapists who responded, the preferred 'key clinical question' for an initial encounter was: "Do you want to just tell me a little bit about [your 'problem presentation'] first of all?"; and for follow-up encounters: 'How have you been since I last saw you?' These results provide an important and novel contribution to the profession, as debate on this issue has not previously been published. Although the sample size in this study is small, the aim of this paper is to generate reflection and debate among clinicians on their preferences for opening patient encounters and optimising the non-specific treatment effects.

    PURPOSE Community-based testing may identify young adults in the general population with sexually transmitted chlamydial infection. To develop selective screening guidelines appropriate for community settings, the authors conducted a cross-sectional analysis of the National Longitudinal Study of Adolescent Health Wave III (April 2, 2001 – May 9, 2002). METHODS Separately for women and men, we developed three predictive models using unconditional multiple logistic regression for survey data. To account for racial/ethnic disparity in prevalence, initial models included identical predictor characteristics plus information on 1) respondent’s race/ethnicity; or 2) respondent’s most recent partner’s race/ethnicity; or 3) no information on race/ethnicity. RESULTS C. trachomatis diagnosis was available for 10,928 (88.6%) of the sexually experienced respondents. A combination of five characteristics for women and six characteristics for men identified approximately 80% of infections while testing ≤50% of the population. Information regarding race/ethnicity dramatically affected algorithm performance. CONCLUSION Using race/ethnicity in any screening algorithm is problematic and controversial, but the model without race information missed many diagnoses in the minority groups. Universal screening in high prevalence regions and selective screening in low prevalence regions may be one method of reaching the affected populations while avoiding the stigma of guidelines incorporating race/ethnicity.

    2016-12-01

    Vaccination in non-medical settings is recommended as a strategy to increase access to seasonal influenza vaccine. To evaluate change in early-season influenza vaccination setting, we analyzed data from the National Internet Flu Survey. Bivariate comparison of respondent characteristics by location of vaccination was assessed using chi-square tests. Multinomial logistic regression was performed to compare the predicted probability of being vaccinated in medical, retail, and mobile settings in 2012 vs 2013. In both 2012 and 2013, vaccination in medical settings was more likely among elderly adults, those with chronic conditions, and adults with a high school education or less. Adults 18-64 without a chronic condition had a lower probability of vaccination in the medical setting, and higher probability of vaccination in a retail or mobile setting, in 2013 compared to 2012. Adults 18-64 with a chronic condition had no change in their location of flu vaccination. Elderly adults had a lower probability of vaccination in the medical setting, and higher probability of vaccination in a retail setting, in 2013 compared to 2012. Non-medical settings continue to play an increasing role in influenza vaccination of adults, particularly for adults without a chronic condition and elderly adults. Retail and mobile settings should continue to be viewed as important mechanisms to ensure broad access to influenza vaccination. PMID:27486562

  16. Inattentional blindness in older adults: Effects of attentional set and to-be-ignored distractors.

    PubMed

    Horwood, Sally; Beanland, Vanessa

    2016-04-01

    Inattentional blindness (IB) involves failing to detect an unexpected visual stimulus while undertaking another task. Previous research has predominantly investigated IB using young adult samples, with few studies exploring whether or how an observer's age affects their detection of unexpected events. To help address this gap, we compared younger adults (18-25 years of age) and older adults (60-80 years of age) on two IB tasks: one dynamic, one static. In the static task, older age was associated with substantially increased IB rates: 89 % for older adults versus 5 % for younger adults. In the dynamic task, we systematically manipulated the presence of to-be-ignored distractors and whether the unexpected stimulus color matched the observers' attentional set. We found a main effect of age on IB: As in the static task, older age was associated with increased IB rates (38 % for older adults vs. 8 % for younger adults). The presence of to-be-ignored distractors and attentional set mismatch interacted to substantially increase IB rates, but age did not interact with either factor. Overall, the results indicate that older age is associated with large increases in IB rates across a range of tasks. The pattern of results is consistent with attentional capacity models of cognitive aging, suggesting that older adults' reduced cognitive resources result in failure to consciously process stimuli that are inconsistent with their attentional set.

    2016-01-01

    Abstract Objective To describe health-related quality of life (HRQOL) conceptual frameworks, critically review 3 commonly used HRQOL scales relevant to adults with chronic conditions in primary care settings, and make recommendations for using HRQOL scales in primary care practice. Data sources Information was accessed regarding HRQOL conceptual and theoretical approaches. A comprehensive search strategy identified 3 commonly used scales that met the review criteria and evidence regarding use of the scales in adults with chronic conditions in community settings. Scale selection Scales were selected if they were designed for clinical use; were easy to administer; were generic and broad in content areas; and contained some individualized items. Scales were critiqued according to content development, theoretical basis, psychometric properties, scoring, feasibility, the concepts being measured, and the number of items that measured an individualized concept. Synthesis Early HRQOL approaches focused on health and functional status while recent approaches incorporate individualized concepts such as the person’s own values and the environment. The abbreviated World Health Organization Quality of Life Scale (WHOQOL-BREF), the 36-Item Short Form Health Survey (SF-36), and the Duke Health Profile were critiqued. All address physical, mental, and social domains, while the WHOQOL-BREF also addresses environment. Psychometric evidence supports use of the SF-36 and WHOQOL-BREF with this population. The SF-36 has the most evidence of responsiveness but has some floor and ceiling effects, while the WHOQOL-BREF does not appear to have floor or ceiling effects but has limited evidence of responsiveness. The WHOQOL-BREF has the highest proportion of individualized items. Conclusion Measurement of HRQOL in adults with chronic conditions can support patient management and contribute to primary care service evaluation. Scales that are based on a broad definition of health and that

    2015-01-01

    Introduction In recent years, client-centered care has been embraced as a new philosophy of care by many organizations around the world. Clinicians and researchers have identified the need for valid and reliable outcome measures that are easy to use to evaluate success of implementation of new concepts. Objective The current study was developed to complete adaptation and field testing of the companion patient-reported measures of processes of care for adults (MPOC-A) and the service provider self-reflection measure of processes of care for service providers working with adult clients (MPOC-SP(A)). Design A validation study Settings In-patient rehabilitation facilities. Main outcome measures MPOC-A and measure of processes of care for service providers working with adult clients (MPOC-SP(A)). Results Three hundred and eighty-four health care providers, 61 patients, and 16 family members completed the questionnaires. Good to excellent internal consistency (0.71–0.88 for health care professionals, 0.82–0.90 for patients, and 0.87–0.94 for family members), as well as moderate to good correlations between domains (0.40–0.78 for health care professionals and 0.52–0.84 for clients) supported internal reliability of the tools. Exploratory factor analysis of the MPOC-SP(A) responses supported the multidimensionality of the questionnaire. Conclusion MPOC-A and MPOC-SP(A) are valid and reliable tools to assess patient and service-provider accounts, respectively, of the extent to which they experience, or are able to provide, client-centered service. Research should now be undertaken to explore in more detail the relationships between client experience and provider reports of their own behavior. PMID:26089710

    Emotional development is one of the largest and most productive areas of psychological research. For decades, researchers have been fascinated by how humans respond to, detect, and interpret emotional facial expressions. Much of the research in this area has relied on controlled stimulus sets of adults posing various facial expressions. Here we introduce a new stimulus set of emotional facial expressions into the domain of research on emotional development—The Child Affective Facial Expression set (CAFE). The CAFE set features photographs of a racially and ethnically diverse group of 2- to 8-year-old children posing for six emotional facial expressions—angry, fearful, sad, happy, surprised, and disgusted—and a neutral face. In the current work, we describe the set and report validity and reliability data on the set from 100 untrained adult participants. PMID:25610415

    NASA's 2006 Solar System Exploration (SSE) Strategic Roadmap identified a set of proposed large Flagship, medium New Frontiers and small Discovery class missions, addressing key exploration objectives. These objectives respond to the recommendations by the National Research Council (NRC), reported in the SSE Decadal Survey. The SSE Roadmap is down-selected from an over-subscribed set of missions, called the SSE Design Reference Mission (DRM) set. Missions in the Flagship and New Frontiers classes can consider Radioisotope Power Systems (RPSs), while small Discovery class missions are not permitted to use them, due to cost constraints. In line with the SSE DRM set and the SSE Roadmap missions, the RPS DRM set represents a set of missions, which can be enabled or enhanced by RPS technologies. At present, NASA has proposed the development of two new types of RPSs. These are the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG), with static power conversion; and the Stirling Radioisotope Generator (SRG), with dynamic conversion. Advanced RPSs, under consideration for possible development, aim to increase specific power levels. In effect, this would either increase electric power generation for the same amount of fuel, or reduce fuel requirements for the same power output, compared to the proposed MMRTG or SRG. Operating environments could also influence the design, such that an RPS on the proposed Titan Explorer would use smaller fins to minimize heat rejection in the extreme cold environment; while the Venus Mobile Explorer long-lived in-situ mission would require the development of a new RPS, in order to tolerate the extreme hot environment, and to simultaneously provide active cooling to the payload and other electric components. This paper discusses NASA's SSE RPS DRM set, in line with the SSE DRM set. It gives a qualitative assessment regarding the impact of various RPS technology and configuration options on potential mission architectures, which could

    Past population estimates of adult walleyes Stizostedion vitreum can be used to set harvest quotas, provided that temporal variability in abundance of adult walleyes is accounted for. We used a long-term data set from Escanaba Lake, Wisconsin, to evaluate the accuracy of past population estimates for setting current-year quotas for adult walleyes. The results from Escanaba Lake were corroborated by comparison with other lakes where adult walleye abundance was estimated in more than 1 year. The accuracy of estimates of adult walleye abundance declined over time from the year the estimate was obtained to the year it was used to set a harvest quota. We derived safety factors for application to past estimates of population size; these factors limit the occurrence of an exploitation rate exceeding the maximum sustainable rate (35%) to approximately 1 in 40. These safety factors declined from 35% for 1-year-old estimates to less than 20% for 10-year-old estimates.

    Recovery-oriented care acknowledges the unique journey that consumers lead with the aim of regaining control of their lives in order to live a good life. Recovery has become a dominant policy-directed model of many mental health care organizations, but in older-adult acute mental health inpatient settings, nurses do not have a clear description of how to be recovery-oriented. The aims of this study were to determine the extent to which elements of existing nursing practice resemble the domains of recovery-oriented care and provide a baseline understanding of practice in preparation for transformation to recovery-oriented mental health care provision. An exploratory, qualitative research design was used to meet the research aims. A purposive sample of mental health nurses (N = 12) participated in focus groups in three older-adult inpatient settings in Australia. A general inductive approach was used to analyze the qualitative data. The mental health nurses in this study readily discussed aspects of their current practice within the recovery domains. They described pragmatic ways to promote a culture of hope, collaborative partnerships, meaningful engagement, autonomy and self-determination, and community participation and citizenship. Nurses also discussed challenges and barriers to recovery-oriented care in older-adult acute mental health settings. This study identified a reasonable baseline understanding of practice in preparation for transformation to recovery-oriented older-adult mental healthcare provision. A concerted drive focused on recovery education is required to effectively embed a recovery-orientated paradigm into older-adult mental health settings. PMID:25263738

    1982-01-01

    In an effort to minimise traffic in the distribution network of a static dataflow machine, the design of the system includes alternative data paths so that data movement may take place over shorter paths when this is permissible. The main emphasis of this approach is to allow the rapid transfer of data in sequential code segments residing in single memory blocks. The objective of data movement minimisation has also influenced the design of the instruction set. In this case, composite, that is, multi-actor, instructions have been proposed as an effective strategy. These principles are illustrated by defining controlled instructions which are especially useful in the management of loops. 9 references.

  12. Using Design Capability Indices to Satisfy Ranged Sets of Design Requirements

    NASA Technical Reports Server (NTRS)

    1996-01-01

    For robust design it is desirable to allow the design requirements to vary within a certain range rather than setting point targets. This is particularly important during the early stages of design when little is known about the system and its requirements. Toward this end, design capability indices are developed in this paper to assess the capability of a family of designs, represented by a range of top-level design specifications, to satisfy a ranged set of design requirements. Design capability indices are based on process capability indices from statistical process control and provide a single objective, alternate approach to the use of Taguchi's signal-to- noise ratio which is often used for robust design. Successful implementation of design capability indices ensures that a family of designs conforms to a given ranged set of design requirements. To demonstrate an application and the usefulness of design capability indices, the design of a solar powered irrigation system is presented. Our focus in this paper is on the development and implementation of design capability indices as an alternate approach to the use of the signal-to-noise ratio and not on the results of the example problem, per se.

    2006-01-01

    What capacity do chronically mentally ill adults have for envisioning personal development as evidenced by the ability to set therapeutic goals? This study explored how individual differences in ego development (Loevinger, 1976) predict the therapeutic goal-setting capacities of adults with chronic mental illness receiving therapy in a community mental health setting. The sample included 51 men and 49 women, ages 25 to 65, diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder. Utilizing correlational and multiple regression analyses, results confirmed a relationship between higher stages of ego development and greater complexity of therapeutic goals, as well as greater commitment to therapeutic goals. Rehabilitation goals were more prevalent at lower stages of ego development, while goals such as enhancing one's personal relationships, and gaining increased insight emerged at higher stages. Implications for therapeutic change are discussed. PMID:17340946

  14. Optimization of massive countermeasure design in complex rockfall settings

    NASA Astrophysics Data System (ADS)

    Agliardi, Federico; Crosta, Giovanni B.

    2015-04-01

    Rockfall protection is a major need in areas impended by subvertical rockwalls with complex 3D morphology and little or no talus to provide natural rockfall attenuation. The design of massive embankments, usually required to ensure such protection, is particularly difficult in complex rockfall settings, due to: widespread occurrence of rockfall sources; difficult characterization of size distribution and location of unstable volumes; variability of failure mechanisms; spatial scattering of rockfall trajectories; high expected kinetic energies. Moreover, rockwalls in complex lithological and structural settings are often prone to mass falls related to rock mass sector collapses. All these issues may hamper a safe application of classic embankment analysis approaches, using empirical rules or 2D-based height/energy statistics, and point to the need of integrated analyses of rock slope instability and rockfall runout in 3D. We explore the potential of combining advanced rock mass characterisation techniques and 3D rockfall modelling to support challenging countermeasure design at a site near Lecco (Southern Alps, Italy). Here subvertical cliffs up to 600 m high impend on a narrow (< 150 m) strip of flat land along the Como Lake shore. Rock is thickly bedded limestone (Dolomia Principale Fm) involved in a ENE-trending, S-verging kilometre-scale anticline fold. The spatial variability of bedding attitude and fracture intensity is strongly controlled by the geological structure, with individual block sizes varying in the range 0.2-15 m3. This results in spatially variable rockfall susceptibility and mechanisms, from single block falls to mass falls. Several rockfall events occurred between 1981 and 2010 motivated the design of slope benching and a massive embankment. To support reliable design verification and optimization we performed a 3D assessment of both rock slope instability and rockfall runout. We characterised fracture patterns and rock mass quality associated

    Within the past decade, there has been a surge of interest in investigating the effects of clown intervention in a large variety of clinical settings. Many studies have focused on the effects of clown intervention on children. However, few studies have investigated clowning effects on adults. This paper presents an overview of the concept of medical clowning followed by a literature review conducted on the empirical studies drawn from three data bases (PubMed, PsycINFO, and Google Scholar), with the aim of mapping and discussing the evidence of clowning effects on non-children, namely adults. The following areas were investigated: Adult and elderly patients (mainly those with dementia), observers of clowning, namely non-hospitalized adults who are at the hospital as relatives of patients or health-care staff, and finally clowns themselves. The main results are that 1) clown intervention induces positive emotions, thereby enhancing the patient’s well-being, reduces psychological symptoms and emotional reactivity, and prompts a decrease in negative emotions, such as anxiety and stress; 2) clown doctors are also well-perceived by relatives and healthcare staff and their presence appears to be useful in creating a lighter atmosphere in the health setting; 3) few pilot studies have been conducted on clown doctors and this lacuna represents a subject for future research.

    Few well-controlled studies have considered neurofeedback treatment in adult psychiatric patients. In this regard, the present study investigates the characteristics and effects of neurofeedback on adult psychiatric patients in a naturalistic setting. A total of 77 adult patients with psychiatric disorders participated in this study. Demographic data and neurofeedback states were retrospectively analyzed, and the effects of neurofeedback were evaluated using clinical global impression (CGI) and subjective self-rating scales. Depressive disorders were the most common psychiatric disorders (19; 24.7 %), followed by anxiety disorders (18; 23.4 %). A total of 69 patients (89.6 %) took medicine, and the average frequency of neurofeedback was 17.39 ± 16.64. Neurofeedback was applied to a total of 39 patients (50.6 %) more than 10 times, and 48 patients (62.3 %) received both β/SMR and α/θ training. The discontinuation rate was 33.8 % (26 patients). There was significant difference between pretreatment and posttreatment CGI scores (<.001), and the self-rating scale also showed significant differences in depressive symptoms, anxiety, and inattention (<.001). This is a naturalistic study in a clinical setting, and has several limitations, including the absence of a control group and a heterogenous sample. Despite these limitations, the study demonstrates the potential of neurofeedback as an effective complimentary treatment for adult patients with psychiatric disorders. PMID:25740085

    Increasing evidence suggests that symptoms of attention deficit hyperactivity disorder (ADHD) could persist into adult life in a substantial proportion of cases. The aim of the present study was to investigate the impact of (1) adverse events, (2) personality traits and (3) genetic variants chosen on the basis of previous findings and (4) their possible interactions on adult ADHD severity. One hundred and ten individuals diagnosed with adult ADHD were evaluated for occurrence of adverse events in childhood and adulthood, and personality traits by the Temperament and Character Inventory (TCI). Common polymorphisms within a set of nine important candidate genes (SLC6A3, DBH, DRD4, DRD5, HTR2A, CHRNA7, BDNF, PRKG1 and TAAR9) were genotyped for each subject. Life events, personality traits and genetic variations were analyzed in relationship to severity of current symptoms, according to the Brown Attention Deficit Disorder Scale (BADDS). Genetic variations were not significantly associated with severity of ADHD symptoms. Life stressors displayed only a minor effect as compared to personality traits. Indeed, symptoms' severity was significantly correlated with the temperamental trait of Harm avoidance and the character trait of Self directedness. The results of the present work are in line with previous evidence of a significant correlation between some personality traits and adult ADHD. However, several limitations such as the small sample size and the exclusion of patients with other severe comorbid psychiatric disorders could have influenced the significance of present findings.

    The analysis of space science data often requires researchers to work with many different types of data. For instance, correlative analysis can require data from multiple instruments on a single spacecraft, multiple spacecraft, and ground-based data. Typically, data from each source are available in a different format and have been written on a different type of computer, and so much effort must be spent to read the data and convert it to the computer and format that the researchers use in their analysis. The large and ever-growing amount of data and the large investment by the scientific community in software that require a specific data format make using standard data formats impractical. A format-independent approach to accessing and analyzing disparate data is key to being able to deliver data to a diverse community in a timely fashion. The system in use at the Planetary Plasma Interactions (PPI) node of the NASA Planetary Data System (PDS) is based on the object-oriented Distributed Inventory Tracking and Data Ordering Specification (DITDOS), which describes data inventories in a storage independent way. The specifications have been designed to make it possible to build DITDOS compliant inventories that can exist on portable media such as CD-ROM's. The portable media can be moved within a system, or from system to system, and still be used without modification. Several applications have been developed to work with DITDOS compliant data holdings. One is a windows-based client/server application, which helps guide the user in the selection of data. A user can select a data base, then a data set, then a specific data file, and then either order the data and receive it immediately if it is online or request that it be brought online if it is not. A user can also view data by any of the supported methods. DITDOS makes it possible to use already existing applications for data-specific actions, and this is done whenever possible. Another application is a stand

    Summary The authors set out to examine qualitatively the use of antiepileptic drugs (AEDs) in a population of older adults in a nursing home setting, evaluating aspects such as specialist prescriptions and changes in dosage. This retrospective prevalence study was carried out in a state-funded nursing home that provides care and rehabilitation for elderly people. The first objective of the study was to determine the prevalence of AED use in this population. The second objective was to monitor AED dosage modifications during the fifteen-month study period, focusing on the safety and the tolerability of AEDs. In the period of time considered, 129 of 402 monitored patients received at least one anti-epileptic therapy. The prevalence of AED use was therefore 32%. Gabapentin was found to be the most commonly prescribed drug, with a frequency of 29%, and it was used mainly for anxiety disorders, psychosis, neuropathic pain and mood disorders. PMID:27358221

    A monosyllabic word test was administered to 114 postlingually-deaf adult cochlear implant (CI) recipients at numerous intervals from two weeks to two years post-initial CI activation. Biographic/audiologic information, electrode position, and cognitive ability were examined to determine factors affecting CI outcomes. Results revealed that Duration of Severe-to-Profound Hearing Loss, Age at Implantation, CI Sound-field Threshold Levels, Percentage of Electrodes in Scala Vestibuli, Medio-lateral Electrode Position, Insertion Depth, and Cognition were among the factors that affected performance. Knowledge of how factors affect performance can influence counseling, device fitting, and rehabilitation for patients and may contribute to improved device design. PMID:23348845

    At least four academic clinical trials have demonstrated the utility of cognitive behavior therapy (CBT) for older adults with generalized anxiety disorder (GAD). These data may not generalize, however, to more heterogeneous and functionally impaired patients and the medical settings in which they typically receive care. A recent pilot project suggested the potential benefits of a new version of CBT for GAD among older patients in primary care. The manual developed and tested in this pilot project is presented here. Treatment components include motivation and education, relaxation skills, cognitive therapy, problem-solving-skills training, exposure exercises, and sleep-management-skills training. Procedures are designed to be administered flexibly to maximize attention to individual patient needs. Examples of session summaries, patient handouts, and homework forms are provided. PMID:14710708

    This paper presents a new charge compensation (CC) scheme to mitigate single event transient (SET) effect at the output node of the charge pump (CP), the most SET vulnerable node in a Phase-Locked Loop (PLL). It achieves a 4X less SET-induced voltage disturbance at the ring oscillator control node as well as a faster PLL recovery time. During the normal operation, the CC circuit does not affect the PLL dynamics. Its control block ensures that the CC circuit is enabled only when the CP output voltage is disturbed by SET strikes. This avoids the conflict between SET charge compensation and normal PLL phase correction. The PLL covers a 12.5 MHz to 500 MHz tuning range with a root-mean-square (RMS) jitter of 4.9 ps. It consumes 21.5 mW of power under a 1.5 V power supply. The CC circuit consumes 4.5 mW power and occupies 5.3% of the PLL area.

    The models studied include an accounting framework type energy demand model, a dynamic linear programming energy supply and conversion system model, an input-output model, a macroeconomic model, and an oil trade gaming model. They are incorporated in an integrated set for long-term, global analyses. This set makes use of a highly iterative process for energy scenario projections and analyses. Each model is quite simple and straightforward in structure; a great deal of human judgement is necessary in applying the set. The models are applied to study two alternative energy scenarios for a coming fifty year period. Examples are presented revealing the wealth of information that can be obtained from multimodel techniques. Details are given for several models (equations employed, assumptions made, data used).

    The problem of choosing an optimal signal set for non-Gaussian detection was reduced to a smooth inequality constrained mini-max nonlinear programming problem by Gockenbach and Kearsley. Here we consider the application of several optimization algorithms, both global and local, to this problem. The most promising results are obtained when special-purpose sequential quadratic programming (SQP) algorithms are embedded into stochastic global algorithms.

    2014-01-01

    Background Young adults are at risk for weight gain. Little is known about how to design weight control programs to meet the needs of young adults and few theory-based interventions have been evaluated in a randomized control trial. The Choosing Healthy Options in College Environments and Settings (CHOICES) study was funded to create a technology-based program for 2-year community college students to help prevent unhealthy weight gain. The purpose of this paper is to: 1) provide a brief background on weight-related interventions in young adults; 2) describe the study design for the CHOICES study, the conceptual model guiding the research and the CHOICES intervention; and 3) discuss implications of this research for health educators. Translation to Health Education Practice Our experiences from the CHOICES study will be useful in suggesting other theory-based models and intervention strategies that might be helpful in programs attempting to prevent unhealthy weight gain in young adults. In addition, this paper discusses important considerations for working with 2-year colleges on this type of health promotion work. PMID:24910855

    2014-01-01

    Objectives To evaluate the reliability and validity of brief subjective measures of numeracy and general health literacy in the adult emergency department setting. Methods A convenience sample of adult emergency department patients completed subjective measures of general health literacy (Short Literacy Screening questions, SLS) and numeracy (Subjective Numeracy Scale, SNS). These patients also completed two objective tests of literacy (the Short Test of Functional Health Literacy in Adults, S-TOFHLA; and the Rapid Estimate of Adult Literacy in Medicine, REALM) and an objective test of numeracy (WRAT4). Internal reliability of the subjective measures was assessed using Cronbach’s alpha. Construct validity of the subjective measures was assessed by correlating them against the S-TOFHLA, REALM, and WRAT4, using Spearman’s rank correlation coefficients, receiver operating characteristics (ROC) curves, and hierarchical, multiple linear regression with adjustment for patient age, gender, race, and education. Results The median age of the 207 patients surveyed was 46 (interquartile range 32, 59); twenty-seven percent were African American. Sixty-one percent of patients reported their highest level of education was high school or below. As measured by the S-TOFHLA and REALM, most patients had adequate literacy levels (89% and 80%, respectively), while 44% of patients had below average numeracy skills on the WRAT4. Median SLS was 14 (IQR 12, 15) on a scale of 3 to 15; median SNS was 36 (IQR 30, 42) on a scale of 6 to 48. The SLS and SNS had good internal reliability, with Cronbach’s alphas of 0.74 and 0.82, respectively. The SLS Spearman’s rank order correlation coefficient was 0.33 (95% confidence interval 0.20, 0.45) for the S-TOFHLA, with a standardized beta coefficient of 0.36 (p<0.05) after adjustment for patient demographics. The SLS correlation coefficient was 0.26 (95% CI 0.13, 0.38) for the REALM, with a standardized beta coefficient of 0.38 (p<0.05) after

  16. Modelling adult Aedes aegypti and Aedes albopictus survival at different temperatures in laboratory and field settings

    PubMed Central

    2013-01-01

    Background The survival of adult female Aedes mosquitoes is a critical component of their ability to transmit pathogens such as dengue viruses. One of the principal determinants of Aedes survival is temperature, which has been associated with seasonal changes in Aedes populations and limits their geographical distribution. The effects of temperature and other sources of mortality have been studied in the field, often via mark-release-recapture experiments, and under controlled conditions in the laboratory. Survival results differ and reconciling predictions between the two settings has been hindered by variable measurements from different experimental protocols, lack of precision in measuring survival of free-ranging mosquitoes, and uncertainty about the role of age-dependent mortality in the field. Methods Here we apply generalised additive models to data from 351 published adult Ae. aegypti and Ae. albopictus survival experiments in the laboratory to create survival models for each species across their range of viable temperatures. These models are then adjusted to estimate survival at different temperatures in the field using data from 59 Ae. aegypti and Ae. albopictus field survivorship experiments. The uncertainty at each stage of the modelling process is propagated through to provide confidence intervals around our predictions. Results Our results indicate that adult Ae. albopictus has higher survival than Ae. aegypti in the laboratory and field, however, Ae. aegypti can tolerate a wider range of temperatures. A full breakdown of survival by age and temperature is given for both species. The differences between laboratory and field models also give insight into the relative contributions to mortality from temperature, other environmental factors, and senescence and over what ranges these factors can be important. Conclusions Our results support the importance of producing site-specific mosquito survival estimates. By including fluctuating temperature regimes

  17. Texting and walking: effect of environmental setting and task prioritization on dual-task interference in healthy young adults.

    2015-01-01

    Recent studies have shown that young adults significantly reduce their gait speed and weave more when texting while walking. Previous research has not examined the simultaneous dual-task effects on texting performance, therefore, the attention prioritization strategy used by young adults while texting and walking is not currently known. Moreover, it is not known whether laboratory-based studies accurately reflect texting and walking performance in the real world. This study compared dual-task interference during texting and walking between laboratory and real-world settings, and examined the ability of young adults to flexibly prioritize their attention between the two tasks in each environment. Texting and walking were assessed in single-task and three dual-task conditions (no-priority, gait-priority, texting-priority) in the lab and a University Student Center, in 32 healthy young adults. Dual-task effects on gait speed, texting speed, and texting accuracy were significant, but did not significantly differ between the two environments. Young adults were able to flexibly prioritize their attention between texting and walking, according to specific instruction, and this ability was not influenced by environmental setting. In the absence of instructions, young adults prioritized the texting task in the low-distraction environment, but displayed more equal focus between tasks in the real world. The finding that young adults do not significantly modify their texting and walking behavior in high-distraction environments lends weight to growing concerns about cell phone use and pedestrian safety.

    This paper describes the results of an interview study investigating facilitators and barriers to adoption of patient portals among low-income, older adults in rural and urban populations in the southeastern United States. We describe attitudes of this population of older adults and their current level of technology use and patient portal use. From qualitative analysis of 36 patient interviews and 16 caregiver interviews within these communities, we derive themes related to benefits of portals, barriers to use, concerns and desired features. Based on our initial findings, we present a set of considerations for designing the patient portal user experience, aimed at helping healthcare clinics to meet U.S. federally-mandated ‘meaningful use’ requirements.

    2015-01-01

    This study employed quantitative and qualitative research approaches to investigate what constitutes “success” in Adult Basic Education (ABE) programs from the perspectives of multiple educational stakeholders: the state funding agency, the teachers, and the students. Success was defined in multiple ways. In the quantitative section of the study, we computed classroom value-added scores (used as a metric of the state’s definition of success) to identify more and less effective ABE classrooms in two Florida counties. In the qualitative section of the study, we observed and conducted interviews with teachers and students in the selected classrooms to investigate how these stakeholders defined success in ABE. Iterative consideration of the qualitative data revealed three principal markers of success: (a) instructional strategies and teacher-student interactions; (b) views on standardized testing; and (c) student motivational factors. In general, classrooms with higher value-added scores were characterized by multiple instructional approaches, positive and collaborative teacher-student interactions, and students engaging in goal setting and citing motivational factors such as family and personal fulfillment. The implications for ABE programs are discussed. PMID:26279590

    [Purpose] The purpose of this study was to examine the associations between the settings of exercise habits and health-related outcomes in community-dwelling older adults. [Subjects] A total of 304 Japanese community-dwelling older adults (70.3 ± 4.1 years; 113 males and 191 females) participated in this study. [Methods] Demographic characteristics, medical conditions, exercise habits, and health-related outcomes were assessed by face-to-face interviews and self-reported questionnaires. Older adults who had exercise habits were classified into two groups: individual- and group-based exercise habits groups, and the health-related outcomes were compared between groups. [Results] The scores for the Geriatric Depression Scale, exercise self-efficacy, and dietary variety of older adults who had group-based exercise habits were better than those of older adults who had individual-based exercise habits. In addition, the exercise settings (individual- and group-based) were significantly associated with scores for the Geriatric Depression Scale (odds ratio = 0.76) and exercise self-efficacy (odds ratio = 1.26), even after adjusting for age and gender. [Conclusion] These results implied that habitual exercise in group settings may have an effective role in promoting exercise self-efficacy and mental health. PMID:26311955

    2016-01-01

    Background Walking can improve functional status, and a pedometer and goal setting can increase walking and, potentially, gait speed. The efficacy of pedometer use and goal setting for increasing step counts among overweight and obese adults with multiple comorbid conditions has not been evaluated. Methods We recruited and randomly assigned obese or overweight adults with multimorbidity to immediate pedometer use with goal setting or delayed pedometer use, using a crossover design. The primary outcome of interest was step count, with secondary outcomes of gait speed and grip strength, with comparison between the intervention and delayed pedometer groups. Results Mean (standard deviation [SD]) age of the 130 participants was 63.4 (15.0) years. At 2 months, mean (SD) steps for the immediate pedometer use group (n=64) was 5,337 (3,096), compared with 4,446 (2,422) steps in the delayed pedometer group (n=66) (P=0.08). Within-group step count increased nonsignificantly, by 179 steps in the immediate pedometer group and 212 steps in the delayed pedometer group after 2 months of intervention, with no significant difference between the groups. Gait speed significantly increased by 0.08 m/s (P<0.05) and grip strength significantly increased by 1.6 kg (P<0.05) in the immediate pedometer group. Conclusion Pedometer use and goal setting did not significantly increase step count among overweight and obese adults with multimorbidity. The absolute step count was lower than many reported averages. Gait speed and grip strength increased with immediate pedometer use. The use of pedometers and goal setting may have an attenuated response in this population. PMID:27621602

  1. Factors associated with constructive staff-family relationships in the care of older adults in the institutional setting.

    PubMed

    Haesler, Emily; Bauer, Michael; Nay, Rhonda

    2006-12-01

    Background  Modern healthcare philosophy espouses the virtues of holistic care and acknowledges that family involvement is appropriate and something to be encouraged due to the role it plays in physical and emotional healing. In the aged care sector, the involvement of families is a strong guarantee of a resident's well-being. The important role family plays in the support and care of the older adult in the residential aged care environment has been enshrined in the Australian Commonwealth Charter of Residents' Rights and Responsibilities and the Aged Care Standards of Practice. Despite wide acknowledgement of the importance of family involvement in the healthcare of the older adult, many barriers to the implementation of participatory family care have been identified in past research. For older adults in the healthcare environment to benefit from the involvement of their family members, healthcare professionals need an understanding of the issues surrounding family presence in the healthcare environment and the strategies to best support it. Objectives  The objectives of the systematic review were to present the best available evidence on the strategies, practices and organisational characteristics that promote constructive staff-family relationships in the care of older adults in the healthcare setting. Specifically this review sought to investigate how staff and family members perceive their relationships with each other; staff characteristics that promote constructive relationships with the family; and interventions that support staff-family relationships. Search strategy  A literature search was performed using the following databases for the years 1990-2005: Ageline, APAIS Health, Australian Family and Society Abstracts (FAMILY), CINAHL, Cochrane Library, Dare, Dissertation Abstracts, Embase, MEDLINE, PsycINFO and Social Science Index. Personal communication from expert panel members was also used to identify studies for inclusion. A second search stage

  14. A candidate-set-free algorithm for generating D-optimal split-plot designs

    PubMed Central

    Jones, Bradley; Goos, Peter

    2007-01-01

    We introduce a new method for generating optimal split-plot designs. These designs are optimal in the sense that they are efficient for estimating the fixed effects of the statistical model that is appropriate given the split-plot design structure. One advantage of the method is that it does not require the prior specification of a candidate set. This makes the production of split-plot designs computationally feasible in situations where the candidate set is too large to be tractable. The method allows for flexible choice of the sample size and supports inclusion of both continuous and categorical factors. The model can be any linear regression model and may include arbitrary polynomial terms in the continuous factors and interaction terms of any order. We demonstrate the usefulness of this flexibility with a 100-run polypropylene experiment involving 11 factors where we found a design that is substantially more efficient than designs that are produced by using other approaches.

    2008-01-01

    This project examined adults' food cognitions by applying schema theory to explain how adults categorized foods for different contexts. Qualitative interviews and repeated card sort activities for different eating contexts were conducted to elicit as many food categories as possible from 42 US adults. Participants labeled card sort piles with their own words, providing 991 card sort labels. Qualitative analysis of the labels resulted in the emergence of 12 category types. Personal-experience-based types were specific to the individual (e.g. Preference). Context-based types were related to situational aspects of eating episodes (e.g. Location). Food-based types were related to intrinsic properties of the foods (e.g. Physical characteristics). Different combinations of the 12 category types were used for different eating contexts. Personal-experience and context-based types were used most frequently overall. Some category types were used more frequently for specific contexts (e.g. Convenience for work contexts). Food-based taxonomic category types were used most frequently when no context was defined. Script-oriented categories were more often used in response to specific eating contexts. These findings provide a framework to consider how individuals classify foods in real-life eating contexts. Attention to personal-experience and context-based category types may help improve understanding of relationships between knowledge and food choice behaviors. PMID:17512088

  16. Ready, set, point: the effects of alertness on prism adaptation in healthy adults.

    PubMed

    2015-05-01

    Prism adaptation (PA) is a promising rehabilitation technique for visuo-spatial neglect, an attention disorder that is characterized by spatial attention deficits (i.e., deficits in orienting). PA involves visuo-motor adaptation to rightward shifting prism goggles. Following goggle removal, this adaptation results in leftward shifts in visuo-motor aiming and amelioration of spatial neglect. Even though some studies clearly support the beneficial effects of PA for spatial neglect, not all studies find benefits, thus it remains unclear how PA effects could be improved. Taking advantage of the known interactions between orienting and alerting reported in the attention literature (i.e., alerting enhances orienting function; e.g., Ishigami and Klein in J Individ Differ 30:220-237. doi: 10.1027/1614-0001.30.4.220 , 2009, in J Neurosci Methods 190:117-28. doi: 10.1016/j.jneumeth.2010.04.019 , 2010; Robertson et al. in Nature 395:169-72. doi: 10.1038/25993 , 1998), we examined the effects of alerting tones on PA with healthy young and older adults. We found that the effects of alerting on PA with young adults were negative, while there was a positive effect with older adults, specifically on a visuo-motor outcome task. Thus, enhancement of PA effects by alerting may be age specific and task specific. Therefore, we can conclude that while the impact of alerting tones is not always positive, further research in patients with neglect may be warranted. PMID:25702160

  17. Financial exploitation of older adults in rural settings: a family perspective.

    2013-01-01

    Federal agencies responsible for funding protective services to older adults are increasingly concerned with the growing incidence of financial exploitation in rural areas. The Wall Street Journal recently has reported an increasing trend of unemployed adult children migrating from urban centers to smaller rural towns and countrysides to live with their parents since 2008. This current study explores the attitudes of family caregivers regarding management of financial matters for their elderly care recipients. The major findings of the study include that adult children often (1) overestimate their parents' ability to manage their finances; (2) prefer to manage their parents' finances informally, as opposed to using legal options like power of attorney; and (3) tend to think of their parents' assets as "almost theirs." The study concludes with recommendations on the critical need for information to help families make important decisions about helping elderly parents with their finances. This information would not only promote the use of safeguards against abuse, but could potentially provide caregivers with greater confidence and protection. PMID:23941423

    This study provides data on the sources of asthma diagnoses in the adult Bangladeshi population in urban and rural settings. The paper also reports the prevalence of self-reported asthma diagnoses and associated socio-demographic factors. A cross-sectional study was conducted in three communities: two rural settings and one urban setting, with a total sample size of 32,665 subjects. Pre-existing surveillance data provided individual socio-demographic factors. Provider categories were based on previous research describing provider plurality in Bangladesh. Descriptive statistics, univariate regression and multivariate regression analyses were performed. Bachelor of Medicine, Bachelor of Surgery (MBBS) generalists provided the largest proportion of diagnoses in both urban (54.6%) and rural (42.4%) sites. The largest proportion of non-MBBS-trained healthcare workers providing diagnoses of asthma was spiritual healers (13.3%) in the urban settings and village doctors (42.4%) in rural settings. The overall prevalence of self-reported asthma diagnoses was 5.0% in the urban population and 3.5% in the rural population. The results highlight the importance of non-MBBS doctors in serving the healthcare needs of the Bangladeshi population. This study reveals a higher prevalence of self-reported asthma diagnoses in the urban setting than in rural ones, which is consistent with international literature on the topic. PMID:23305210

    2016-01-01

    Stress influences a wide variety of outcomes including cognitive processing. In the rat, early life maternal care can influence developing offspring to affect both stress reactivity and cognitive processes in adulthood. The current study assessed if variations in early life maternal care can influence cognitive performance on a task, the ability to switch cognitive sets, dependent on the medial prefrontal cortex. Early in life, offspring was reared under High or Low maternal Licking conditions. As adults, they were trained daily and then tested on an attentional set-shifting task (ASST), which targets cognitive flexibility in rodents. Stress-sensitive behavioral and neural markers were assayed before and after the ASST. High and Low Licking offspring performed equally well on the ASST despite initial, but not later, differences in stress axis functioning. These results suggest that early life maternal care does not impact the accuracy of attentional set-shifting in rats. These findings may be of particular importance for those interested in the relationship between early life experience and adult cognitive function. PMID:26289990

    The extent to which a museum object-handling intervention enhanced older adult well-being across three health care settings was examined. The program aimed to determine whether therapeutic benefits could be measured objectively using clinical scales. Facilitator-led, 30 to 40 min sessions handling and discussing museum objects were conducted in acute and elderly care (11 one-to-ones), residential (4 one-to-ones and 1 group of five), and psychiatric (4 groups of five) settings. Pre-post measures of psychological well-being (Positive Affect and Negative Affect Schedule) and subjective wellness and happiness (Visual Analogue Scales) were compared. Positive affect and wellness increased significantly in acute and elderly and residential care though not psychiatric care whereas negative affect decreased and happiness increased in all settings. Examination of audio recordings revealed enhanced confidence, social interaction, and learning. The program allowed adults access to a museum activity who by virtue of age and ill health would not otherwise have engaged with museum objects. PMID:25421749

    2016-01-01

    Prescription opioid use has increased in recent decades. Although opioids provide effective pain control, their use may be associated with the risk of misuse. Opioid misuse (OM) is prevalent among adolescents and young adults (AYAs). Opioids are necessary to treat cancer-related pain; however, oncology patients are not immune to medication misuse. Research examining OM among AYAs with cancer is scarce. This article examines the risk factors described in the general adult and adolescent medication abuse literature and aims to provide recommendations for practice in the AYA oncology population. The following risk factors should be examined in AYA oncology patients to determine their relevance: age, sex, behavioral and academic problems, psychological conditions, and a history of illicit drug use/abuse. To maintain the delicate balance of providing adequate pain relief while protecting patients from the risk of OM, clinicians must consider potential risk factors, motivating factors, and individual behaviors. Placing these challenges in perspective, this review provides clinical considerations, recommendations, and intervention strategies for OM prevention in AYA oncology patients. PMID:27435441

  7. Extreme Goal Setting and Vulnerability to Mania Among Undiagnosed Young Adults

    2010-01-01

    During euthymia people with bipolar disorder and their unaffected family members accomplish more than the general population. People with bipolar disorder, or those who are at risk for it, also set higher goals in laboratory tasks than other people. The work reported here examines whether persons vulnerable to mania set elevated goals in their lives. In two studies, a measure of lifetime vulnerability to mania was related to traits bearing on incentive sensitivity, and also to endorsement of high ambitions for fame, wealth, and political influence (assessed by a new measure). Relations were weaker to ambitions for other kinds of extreme goals. The effects were independent of current symptoms of mania and depression and lifetime depression. There was also evidence that incentive sensitivity and elevated aspirations made independent contributions to variance in the measure of manic risk. Discussion focuses on the implications of high goal setting for understanding goal dysregulation and mania. PMID:20198117

    Dehalococcoides spp. are an industrially relevant group of Chloroflexi bacteria capable of reductively dechlorinating contaminants in groundwater environments. Existing Dehalococcoides genomes revealed a high level of sequence identity within this group, including 98 to 100% 16S rRNA sequence identity between strains with diverse substrate specificities. Common molecular techniques for identification of microbial populations are often not applicable for distinguishing Dehalococcoides strains. Here we describe an oligonucleotide microarray probe set designed based on clustered Dehalococcoides genes from five different sources (strain DET195, CBDB1, BAV1, and VS genomes and the KB-1 metagenome). This “pangenome” probe set provides coverage of core Dehalococcoides genes as well as strain-specific genes while optimizing the potential for hybridization to closely related, previously unknown Dehalococcoides strains. The pangenome probe set was compared to probe sets designed independently for each of the five Dehalococcoides strains. The pangenome probe set demonstrated better predictability and higher detection of Dehalococcoides genes than strain-specific probe sets on nontarget strains with <99% average nucleotide identity. An in silico analysis of the expected probe hybridization against the recently released Dehalococcoides strain GT genome and additional KB-1 metagenome sequence data indicated that the pangenome probe set performs more robustly than the combined strain-specific probe sets in the detection of genes not included in the original design. The pangenome probe set represents a highly specific, universal tool for the detection and characterization of Dehalococcoides from contaminated sites. It has the potential to become a common platform for Dehalococcoides-focused research, allowing meaningful comparisons between microarray experiments regardless of the strain examined. PMID:21666017

    Experimental investigations at the Air Force Research Laboratory's Munitions Directorate required a firing set to initiate detonators in ultra-high-voltage experiments, but commercial firing sets with adequate high voltage isolation could not be found. To resolve this issue a Directorate team designed, fabricated a new firing set, verified that it met all design requirements, and obtained safety board approval for its use. The patented design uses all plastic fiber optic cables, pneumatic controls, battery isolation, and redundant safety devices to withstand voltage differences of hundreds of thousands of volts between the operator and the experiment. This paper describes the efforts to develop a very reliable firing set that met the high standards required by explosive safety procedures. Design features include Faraday shielding, redundant lock out features, multiple safing circuits to handle a variety of fault conditions and fail-safe bleed down circuits to eliminate concerns with residual stored electrical energy. The high-voltage-tolerant firing set allows research in unexplored areas such as electro-explosive effects.

    Environmental factors have long been known to influence immune responses. In particular, clinical studies about the association between migration and increased risk of atopy/asthma have provided important information on the role of migration associated large sets of environmental exposures in the development of allergic diseases. However, investigations about environmental effects on immune responses are mostly limited in candidate environmental exposures, such as air pollution. The influences of large sets of environmental exposures on immune responses are still largely unknown. A simulated 520-d Mars mission provided an opportunity to investigate this topic. Six healthy males lived in a closed habitat simulating a spacecraft for 520 days. When they exited their "spacecraft" after the mission, the scenario was similar to that of migration, involving exposure to a new set of environmental pollutants and allergens. We measured multiple immune parameters with blood samples at chosen time points after the mission. At the early adaptation stage, highly enhanced cytokine responses were observed upon ex vivo antigen stimulations. For cell population frequencies, we found the subjects displayed increased neutrophils. These results may presumably represent the immune changes occurred in healthy humans when migrating, indicating that large sets of environmental exposures may trigger aberrant immune activity.

    Dental professionals play a key role in maintaining the well-being of older adults by identifying problems that disturb systemic health. A 3-part instrument was used to assess dental students' knowledge of aging, comfort with patient diversity and patient care strategies (Years 1-4; N = 321). Collaborative education and services were developed by the Schools of Dental Medicine and Social Work. Results indicate that dental students' knowledge of aging was low (Palmore's FAQ 1 Range = 58%-64%), comfort with geriatric issues improved after the first year of intervention, and strategies for patient care changed with experience. Group differences suggest the importance of utilizing educational "turning points" as teachable moments. PMID:16873208

    The design of an microprocessor is a long, tedious, and error-prone task consisting of typically three design phases: architecture exploration, software design (assembler, linker, loader, profiler), architecture implementation (RTL generation for FPGA or cell-based ASIC) and verification. The Language for instruction-set architectures (LISA) allows to model a microprocessor not only from instruction-set but also from architecture description including pipelining behavior that allows a design and development tool consistency over all levels of the design. To explore the capability of the LISA processor design platform a.k.a. CoWare Processor Designer we present in this paper three microprocessor designs that implement a 8/8 wavelet transform processor that is typically used in today's FBI fingerprint compression scheme. We have designed a 3 stage pipelined 16 bit RISC processor (NanoBlaze). Although RISC μPs are usually considered "fast" processors due to design concept like constant instruction word size, deep pipelines and many general purpose registers, it turns out that DSP operations consume essential processing time in a RISC processor. In a second step we have used design principles from programmable digital signal processor (PDSP) to improve the throughput of the DWT processor. A multiply-accumulate operation along with indirect addressing operation were the key to achieve higher throughput. A further improvement is possible with today's FPGA technology. Today's FPGAs offer a large number of embedded array multipliers and it is now feasible to design a "true" vector processor (TVP). A multiplication of two vectors can be done in just one clock cycle with our TVP, a complete scalar product in two clock cycles. Code profiling and Xilinx FPGA ISE synthesis results are provided that demonstrate the essential improvement that a TVP has compared with traditional RISC or PDSP designs.

    A voxel phantom of Chinese adult male called CNMAN was constructed from color photographs of the first Chinese visible human data set, for radiation protection purpose. This data set was obtained from a 35-y-old Chinese male cadaver by a medical university in China. The man, 170 cm in height and 65 kg in weight, was dead without any pathological changes. The image size for transversal anatomical photographs of the whole body was 3072 x 2048. After the photographs were semi-automatically segmented, the voxel phantom (CNMAN) with a voxel size of 0.16 mm x 0.16 mm x 1 mm, consisting of 29 tissues or organs was constructed. Combined with the MCNP Monte Carlo transport code, preliminary results for radiation protection dosimetry were obtained based on this Chinese voxel phantom. PMID:17526909

    Connected health devices are generally designed for unsupervised use, by non-healthcare professionals, facilitating independent control of the individuals own healthcare. Older adults are major users of such devices and are a population significantly increasing in size. This group presents challenges due to the wide spectrum of capabilities and attitudes towards technology. The fit between capabilities of the user and demands of the device can be optimised in a process called Human Centred Design. Here we review examples of some connected health devices chosen by random selection, assess older adult known capabilities and attitudes and finally make analytical recommendations for design approaches and design specifications.

    Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality worldwide. The magnitude of the HCV burden has previously been the subject of debate, as representative data tend to exclude high-risk populations, including institutionalized persons. The purpose of this systematic review and meta-analysis was to estimate the prevalence of HCV infection among older adults in long-term care (LTC) and assess factors associated with the prevalence of HCVin this setting. The Preferred Reporting Items for Systematic Review and Meta-Analyses checklist was used as the methodological guide. Two reviewers independently assessed the study quality using a validated modified quality assessment tool. Six articles met inclusion criteria; the majority were cross-sectional studies (83.3 %) designed to estimate HCV infection prevalence rates and identify associated risk factors. HCV prevalence ranged from 1.4 to 11.8 %. A pooled HCV infection prevalence of 3.3 % (95 % confidence interval: 1.5–7.2 %) was estimated based on 1920 LTC residents with substantial heterogeneity noted (Q=51.1, p<0.001; I2=90.2). Three of six studies reported statistically significant factors associated with an increased risk for HCV infection, including older age, female gender, history of blood transfusions, short duration of LTC residence, and hepatitis B virus positivity. This study reports a higher prevalence of HCV infection among older adults in LTC settings compared to community-dwelling older adults; however, accurate estimation of prevalence is limited by heterogeneity between and within studies, variation in sampling and recruitment methodologies, and absence of the HCV-RNA test to confirm active infection.

This has also led to the development of QoL instruments that meet the psychometric criteria necessary for reliable and valid outcome measures in research, health policy decision-making and, increasingly, in clinical practice. Despite the proliferation of QoL instruments available to inform best practice, clinicians seldom routinely apply them. One of the barriers to using QoL instruments is the unfamiliarity nurses have with existing instruments. In order to increase community health nurses' familiarity with existing QoL assessments, the aim of this paper is to describe five instruments and modules that have been developed by the World Health Organization's Quality of Life Assessment Group for the assessment of QoL among healthy and ill adults and to describe how their applicability could enhance evidence-based practice in community nursing.

    Restricted mobility is the most common impairment among older adults and a manual wheelchair is often prescribed to address these limitations. However, limited access to rehabilitation services results in older adults typically receiving little or no mobility training when they receive a wheelchair. As an alternative and novel approach, we developed a therapist-monitored wheelchair skills home training program delivered via a computer tablet. To optimize efficacy and adherence, principles of self-efficacy and adult learning theory were foundational in the program design. A participatory action design approach was used to engage older adult wheelchair users, care providers, and prescribing clinicians in an iterative design and development process. A series of prototypes were fabricated and revised, based on feedback from eight stakeholder focus groups, until a final version was ready for evaluation in a clinical trial. Stakeholder contributions affirmed and enhanced the foundational theoretical principles and provided validation of the final product for the target population. PMID:25276768

    Purpose: With emergence of clinical outcomes databases as tools utilized routinely within institutions, comes need for software tools to support automated statistical analysis of these large data sets and intrainstitutional exchange from independent federated databases to support data pooling. In this paper, the authors present a design approach and analysis methodology that addresses both issues. Methods: A software application was constructed to automate analysis of patient outcomes data using a wide range of statistical metrics, by combining use of C#.Net and R code. The accuracy and speed of the code was evaluated using benchmark data sets. Results: The approach provides data needed to evaluate combinations of statistical measurements for ability to identify patterns of interest in the data. Through application of the tools to a benchmark data set for dose-response threshold and to SBRT lung data sets, an algorithm was developed that uses receiver operator characteristic curves to identify a threshold value and combines use of contingency tables, Fisher exact tests, Welch t-tests, and Kolmogorov-Smirnov tests to filter the large data set to identify values demonstrating dose-response. Kullback-Leibler divergences were used to provide additional confirmation. Conclusions: The work demonstrates the viability of the design approach and the software tool for analysis of large data sets. PMID:24320426

    Evidence-based treatments for adult patients with anxiety are greatly needed within primary care settings. Psychotherapy protocols, including those for cognitive-behavioral therapy (CBT), are often disorder-specific and were developed for specialty mental health settings, rendering them infeasible in primary care. Behavioral health consultants (BHCs) integrated into primary care settings are uniquely positioned to provide anxiety treatment. However, due to the dearth of empirically supported brief treatments for anxiety, BHCs are tasked with adapting existing treatments for use in primary care, which is quite challenging due to the abbreviated format and population-based approach to care. CBT protocols are highly effective in the treatment of anxiety and fit well with the self-management emphasis of integrated primary care. We review the rationale and procedure for 6 evidence-based CBT intervention techniques (psycho-education, mindfulness and acceptance-based behavioral techniques, relaxation training, exposure, cognitive restructuring, and behavioral activation) that can be adapted for use in the brief format typical of integrated primary care. We offer tips based on our clinical experience, highlight resources (e.g., handouts, websites, apps), and discuss 2 case examples to aid BHCs in their everyday practice. Our goal is to provide BHCs with practical knowledge that will facilitate the use of evidence-based interventions to improve the treatment of anxiety in primary care settings.

    It seems safe to conclude that nearly 150 years ago, "the lady with the lamp," Florence Nightingale, set a course that practice-based healthcare researchers continue to follow today. In her book, Notes on Nursing (1860), Nightingale identified light, ventilation, noise, and sanitation as elements of the environment that affected the well-being of soldiers in her care. Today, we attempt to study these same relationships: those that exist between the built environment of healthcare settings, and the health and well-being of the users of these spaces. The goal of this paper is to describe how research is conceptualized, integrated, and utilized in healthcare design decision making and to address the challenges and opportunities that exist when moving a research agenda forward. Numerous examples of design practitioners and healthcare facilities that have committed themselves to integrating research into healthcare design are provided. PMID:21162432

    Objective Evidence indicates that users incur significant physical and cognitive costs in the use of order sets, a core feature of computerized provider order entry systems. This paper develops data-driven approaches for automating the construction of order sets that match closely with user preferences and workflow while minimizing physical and cognitive workload. Materials and methods We developed and tested optimization-based models embedded with clustering techniques using physical and cognitive click cost criteria. By judiciously learning from users’ actual actions, our methods identify items for constituting order sets that are relevant according to historical ordering data and grouped on the basis of order similarity and ordering time. We evaluated performance of the methods using 47 099 orders from the year 2011 for asthma, appendectomy and pneumonia management in a pediatric inpatient setting. Results In comparison with existing order sets, those developed using the new approach significantly reduce the physical and cognitive workload associated with usage by 14–52%. This approach is also capable of accommodating variations in clinical conditions that affect order set usage and development. Discussion There is a critical need to investigate the cognitive complexity imposed on users by complex clinical information systems, and to design their features according to ‘human factors’ best practices. Optimizing order set generation using cognitive cost criteria introduces a new approach that can potentially improve ordering efficiency, reduce unintended variations in order placement, and enhance patient safety. Conclusions We demonstrate that data-driven methods offer a promising approach for designing order sets that are generalizable, data-driven, condition-based, and up to date with current best practices.

    Taking a settings approach to health promotion means addressing the contexts within which people live, work, and play and making these the object of inquiry and intervention as well as the needs and capacities of people to be found in different settings. This approach can increase the likelihood of success because it offers opportunities to situate practice in its context. Members of the setting can optimize interventions for specific contextual contingencies, target crucial factors in the organizational context influencing behavior, and render settings themselves more health promoting. A number of attempts have been made to systematize evidence regarding the effectiveness of interventions in different types of settings (e.g., school-based health promotion, community development). Few, if any, attempts have been made to systematically develop a template or framework for analyzing those features of settings that should influence intervention design and delivery. This article lays out the core elements of such a framework in the form of a nested series of questions to guide analysis. Furthermore, it offers advice on additional considerations that should be taken into account when operationalizing a settings approach in the field. PMID:19809004

  11. Use of Geriatric Assessment for Older Adults in the Oncology Setting: A Systematic Review

    PubMed Central

    2012-01-01

    Background Geriatric assessment is a multidisciplinary diagnostic process that evaluates the older adult’s medical, psychological, social, and functional capacity. No systematic review of the use of geriatric assessment in oncology has been conducted. The goals of this systematic review were: 1) to provide an overview of all geriatric assessment instruments used in the oncology setting; 2) to examine the feasibility and psychometric properties of those instruments; and 3) to systematically evaluate the effectiveness of geriatric assessment in predicting or modifying outcomes (including the impact on treatment decision making, toxicity of treatment, and mortality). Methods We searched Medline, Embase, Psychinfo, Cinahl, and the Cochrane Library for articles published in English, French, Dutch, or German between January 1, 1996, and November 16, 2010, reporting on cross-sectional, longitudinal, interventional, or observational studies that assessed the feasibility or effectiveness of geriatric assessment instruments. The quality of articles was evaluated using relevant quality assessment frameworks. Results We identified 83 articles that reported on 73 studies. The quality of most studies was poor to moderate. Eleven studies examined psychometric properties or diagnostic accuracy of the geriatric assessment instruments used. The assessment generally took 10–45min. Geriatric assessment was most often completed to describe a patient’s health and functional status. Specific domains of geriatric assessment were associated with treatment toxicity in 6 of 9 studies and with mortality in 8 of 16 studies. Of the four studies that examined the impact of geriatric assessment on the cancer treatment decision, two found that geriatric assessment impacted 40%–50% of treatment decisions. Conclusion Geriatric assessment in the oncology setting is feasible, and some domains are associated with adverse outcomes. However, there is limited evidence that geriatric assessment

    Objective To compare incidence and distribution of non-AIDS-defining events (NADEs) among HIV-1-infected adults receiving combination antiretroviral therapy (cART) in urban sub-Saharan African versus United States settings. Design Retrospective cohort analysis of clinical trial and observational data. Methods Compared crude and standardized (to US cohort by age and sex) NADE rates from two urban adult HIV-infected cART-initiating populations: a clinical trial cohort in Gaborone, Botswana (Botswana) and an observational cohort in Nashville, Tennessee (USA). Results Crude NADE incidence rates were similar: 10.0 [95% confidence interval 6.3–15.9] per 1000 person-years in Botswana versus 12.4 [8.4–18.4] per 1000 person-years in the United States. However, after standardizing to an older, predominantly male US population, the overall NADE incidence rates were higher in Botswana [18.7 (8.3–33.1) per 1000 person-years]. Standardized rates differed most for cardiovascular events (8.4 versus 5.0 per 1000 person-years) and non-AIDS-defining malignancies (8.0 versus 0.5 per 1000 person-years) – both higher in Botswana. Conversely, hepatic NADE rates were higher in the United States (4.0 versus 0.0 per 1000 person-years), whereas renal NADE rates [3.0 per 1000 person-years (United States) versus 2.4 per 1000 person-years (Botswana)] were comparable. Conclusion Crude NADE incidence rates were similar between cART-treated patients in a US observational cohort and a sub-Saharan African clinical trial. However, when standardized to the US cohort, overall NADE rates were higher in Botswana. NADEs appear to be a significant problem in our sub-Saharan African setting, and the monitoring, prevention, and treatment of NADEs should be a critical component of care in resource-limited settings.

  13. Comparison of Fuzzy Set and Convex Model Theories in Structural Design

    2001-05-01

    A methodology for the treatment of uncertainty in the loads applied to a structural system using convex models is presented and is compared to the fuzzy set finite-element method. The analytical results for a beam, a truss and a frame structure indicate that the two methods based on convex model or fuzzy set theory are in good agreement for equivalent levels of uncertainty applied to linear structures. Convex model or fuzzy set theories have shown that the worst-case scenario response of all possible load combinations cannot be captured simply by load factorisation, as is the current design practice in building codes. Design problems including uncertainty with a large number of degrees of freedom, that are not computationally feasible using conventional methods described in building codes, can be solved easily using convex model or fuzzy set theory. These results can be used directly and efficiently in the analyses required for the optimal design of structural systems, thus enabling optimisation of complex structural systems with uncertainty.

    Adult learners require alternative learning opportunities to enable them to work and still be able to upgrade their education. This dual format course, combining online and face-to-face components, was developed to meet the need of students to complete a prerequisite undergraduate level neuroanatomy and neurophysiology course while attending a program that included fly-in weekends (seven) and online instruction (15 weeks). A combination of online lectures and on-campus lectures were used to teach pre-requisite neuroanatomy and neurophysiology course topics. The article presents the teaching material division between online and on-campus lectures and presentation of data collected. Survey data collected included student preferred: online media presentation, online activities developed to facilitate learning of the online material, online case study discussion, and testing formats. Students also were asked to comment on whether the class should move to a 100% online format and what their concerns would be moving to an all online format. Additional qualitative data on student input related to the course, adult learning and the learning environment will be presented. Blackboard data include: student daily access patterns, media and documents access and download patterns, and case study participation. Additionally, descriptive statistics from in class quizzes versus online quizzes includes: student patterns of test taking in an unlimited retake environment, scores on retakes and final scores (highest of retakes), in-class quiz scores, and comparison of comprehensive final exam scores from online versus face-to-face lecture material and testing. Findings provide valuable information for online course formatting, revisions and additional course development. PMID:23493658

    This study developed evidence-based clinical practice guidelines for the urinary continence care of adult stroke survivors in acute and rehabilitation settings. The research team conducted a comprehensive review of the literature on urinary continence interventions and outcomes. The team then developed a set of recommendations outlined in the resulting clinical practice guidelines titled Clinical Practice Guidelines (CPGs) for the Urinary Continence Care of Stroke Survivors in Acute and Rehabilitation Settings. The evaluation of the CPGs consisted of a two-part assessment and pilot implementation. An expert panel of 25 local and regional experts in stroke and continence care assessed the proposed CPGs. This assessment consisted of two stages: a) evaluating the guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE) Instrument (http://www. agreetrust.org); and, b) conducting focus groups to identify barriers and facilitators to the implementation of the guidelines using the Ottawa Model of Research Use (OMRU). Results from the expert panel assessments/feedback contributed to the refinement of the CPGs as well as identification and construction of implementation strategies. Two sites conducted a three-month pilot implementation of three recommendations from the CPGs as selected by each site. The two inpatient sites were a rehabilitation setting and a mixed acute and rehabilitation setting. The implementation of the CPGs included the development of learning strategies tailored to the needs of each site and in addition to the creation of an online self-learning portal. This study assessed nurses' knowledge, attitudes, and beliefs regarding urinary continence challenges using a survey before and after the pilot. Chart reviews before and after the pilot implementation audited the nurses' urinary continence practices for patients and uptake of the selected guidelines' recommendations. Study findings suggested the implementation of the CPGs

    Consistent with Western cultural values, the traditional liberal theory of autonomy, which places emphasis on self-determination, liberty of choice, and freedom from interference by others, has been a leading principle in health care discourse for several decades. In context to aging, chronic illness, disability, and long-term care, increasingly there has been a call for a relational conception of autonomy that acknowledges issues of dependency, interdependence, and care relationships. Although autonomy is a core philosophy of assisted living (AL) and a growing number of studies focus on this issue, theory development in this area is lagging and little research has considered race, class, or cultural differences, despite the growing diversity of AL. We present a conceptual model of autonomy in AL based on over a decade of research conducted in diverse facility settings. This relational model provides an important conceptual lens for understanding the dynamic linkages between varieties of factors at multiple levels of social structure that shape residents' ability to maintain a sense of autonomy in this often socially challenging care environment. Social and institutional change, which is ongoing, as well as the multiple and ever-changing cultural contexts within which residents are embedded, are important factors that shape residents' experiences over time and impact resident-facility fit and residents' ability to age in place.

    Background Standing balance is imperative for mobility and avoiding falls. Use of an excessive number of standing balance measures has limited the synthesis of balance intervention data and hampered consistent clinical practice. Objective To develop recommendations for a core outcome set (COS) of standing balance measures for research and practice among adults. Methodology A combination of scoping reviews, literature appraisal, anonymous voting and face-to-face meetings with fourteen invited experts from a range of disciplines with international recognition in balance measurement and falls prevention. Consensus was sought over three rounds using pre-established criteria. Data sources The scoping review identified 56 existing standing balance measures validated in adult populations with evidence of use in the past five years, and these were considered for inclusion in the COS. Results Fifteen measures were excluded after the first round of scoring and a further 36 after round two. Five measures were considered in round three. Two measures reached consensus for recommendation, and the expert panel recommended that at a minimum, either the Berg Balance Scale or Mini Balance Evaluation Systems Test be used when measuring standing balance in adult populations. Limitations Inclusion of two measures in the COS may increase the feasibility of potential uptake, but poses challenges for data synthesis. Adoption of the standing balance COS does not constitute a comprehensive balance assessment for any population, and users should include additional validated measures as appropriate. Conclusions The absence of a gold standard for measuring standing balance has contributed to the proliferation of outcome measures. These recommendations represent an important first step towards greater standardization in the assessment and measurement of this critical skill and will inform clinical research and practice internationally.

    This study examines the use of engineering design to facilitate science reasoning in high-needs, urban classrooms. The Design for Science unit utilizes scaffolds consistent with reform science instruction to assist students in constructing a design solution to satisfy a need from their everyday lives. This provides a meaningful context in which students could reason scientifically. Eighth grade students from two urban schools participated in the unit. Both schools contained large percentages of racial/ethnic minority and economically disadvantaged students. Students demonstrated statistically significant improvement on a paper-and-pencil, multiple-choice pre and post assessment. The results compare favorably with both a high-quality inquiry science unit and a traditional textbook curriculum. Implications for the use of design-based curricula as a viable alternative for teaching science reasoning in high-needs, urban settings are discussed.

    There is a paucity of literature regarding the relationship between the experience of vision loss and depression. Therefore, the current pilot study aimed to explore whether significant differences existed in levels of depression between adults with different vision loss experiences. A group of adults aged between 20 and 65 yr old with irreversible vision loss in a rehabilitation setting was interviewed. Semistructured interviews were conducted in order to explore patients' experience of vision loss. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depressive levels; 39.5% (n = 15) of patients met CES-D criteria for depression. In addition, higher levels of depression (p < 0.05) were identified in patients whose interviews revealed greater self-awareness of impairment, inadequate social support, and longer rehabilitation stay. Current findings draw attention to variables such as self-awareness of impairment and perceived social support and suggest that depression following vision loss may be related to patients' emotional experiences of impairment and adjustment processes.

    A frequency domain method is developed for plant set estimation. The estimation of a plant 'set' rather than a point estimate is required to support many methods of modern robust control design. The approach here is based on using a Schroeder-phased multisinusoid input design which has the special property of placing input energy only at the discrete frequency points used in the computation. A detailed analysis of the statistical properties of the frequency domain estimator is given, leading to exact expressions for the probability distribution of the estimation error, and many important properties. It is shown that, for any nominal parametric plant estimate, one can use these results to construct an overbound on the additive uncertainty to any prescribed statistical confidence. The 'soft' bound thus obtained can be used to replace 'hard' bounds presently used in many robust control analysis and synthesis methods.

    Background Only limited data are available relating to the etiology of diarrhea in children and adults in Senegal. The aim of this prospective study was to describe the epidemiology and etiology of community-acquired diarrheal infections in children and adults living in urban settings. Methods A prospective study was carried out from March 2009 to December 2010, in the urban region of Dakar, Senegal. Patients with acute diarrhea were enrolled, interviewed to collect their clinical history, and their stools were tested for bacteria, virus and parasites. Results A total of 223 patients (including 112 children younger than five years old) with diarrhea were included. At least one enteropathogen was detected in 81% (180/223) of the patients: 29% (64/223) had bacterial infections (mainly diarrheagenic E. coli and Shigella spp), 21% (39/185) viral infections (mainly rotavirus) and 14% (31/223) parasitic infections. Co-infection was identified in 17.8% (32/180) of the patients. Viral infection was significantly more frequent in children under five years old during the dry season. Bacteria and parasites were equally frequent in all age groups. There was a seasonal variation of bacterial infections during the study period, with a higher proportion of infections being bacterial, and due to Salmonella spp. in particular, during the rainy season. Conclusion Our study suggests that in urban settings in Senegal, rotavirus is the principal cause of pediatric diarrhea during the dry season and that the proportion of bacterial infections seems to be higher during the rainy season. Further work is needed to document the burden of diarrheal diseases in sub-Saharan urban communities and to identify risk factors, including those linked to the rapid and unplanned urbanization in Africa.

  5. Why does Japan use the probability method to set design flood?

    2015-12-01

    Design flood is hypothetical flood to make flood prevention plan. In Japan, a probability method based on precipitation data is used to define the scale of design flood: Tone River, the biggest river in Japan, is 1 in 200 years, Shinano River is 1 in 150 years, and so on. It is one of important socio-hydrological issue how to set reasonable and acceptable design flood in a changing world. The method to set design flood vary among countries. Although the probability method is also used in Netherland, but the base data is water level or discharge data and the probability is 1 in 1250 years (in fresh water section). On the other side, USA and China apply the maximum flood method which set the design flood based on the historical or probable maximum flood. This cases can leads a question: "what is the reason why the method vary among countries?" or "why does Japan use the probability method?" The purpose of this study is to clarify the historical process which the probability method was developed in Japan based on the literature. In the late 19the century, the concept of "discharge" and modern river engineering were imported by Dutch engineers, and modern flood prevention plans were developed in Japan. In these plans, the design floods were set based on the historical maximum method. Although the historical maximum method had been used until World War 2, however, the method was changed to the probability method after the war because of limitations of historical maximum method under the specific socio-economic situations: (1) the budget limitation due to the war and the GHQ occupation, (2) the historical floods: Makurazaki typhoon in 1945, Kathleen typhoon in 1947, Ione typhoon in 1948, and so on, attacked Japan and broke the record of historical maximum discharge in main rivers and the flood disasters made the flood prevention projects difficult to complete. Then, Japanese hydrologists imported the hydrological probability statistics from the West to take account of

    Digital desk technology has a still mainly unexplored potential to support the everyday work of collaborating clinicians. This paper presents ER Desk – a digital desk that was designed to specifically support a team of healthcare professionals working in an emergency room setting. The underlying design requirements were elicited in a comprehensive distributed cognition study of paper-based practices in an emergency room of a middle-sized Swedish hospital. We present the user interface and visualization requirements for digital desks for small clinical emergency room teams. Moreover, we discuss key design issues more generally with a focus on supporting team awareness, cognition, and collaborative routines of healthcare personnel working in clinical environments such as emergency rooms and intensive care units.

    Invasive pneumococcal disease causes substantial morbidity and mortality in Africa. Evaluating population level indirect impact on adult disease of pneumococcal conjugate vaccine (PCV) programmes in infants requires baseline population incidence rates but these are often lacking in areas with limited disease surveillance. We used hospital based blood culture and cerebrospinal fluid surveillance to calculate minimal incidence of invasive pneumococcal disease in the adult (≥15 years old) population of Blantyre, a rapidly growing urban centre in southern Malawi, in the period preceding vaccine introduction. Invasive pneumococcal disease incidence in Blantyre district was high, mean 58.1 (95% confidence interval (CI): 53.7, 62.7) per 100,000 person years and peaking among 35 to 40 year olds at 108.8 (95%CI: 89.0, 131.7) mirroring the population age prevalence of HIV infection. For pneumococcal bacteraemia in urban Blantyre, mean incidence was 60.6 (95% CI: 55.2, 66.5) per 100,000 person years, peaking among 35 to 40 year olds at 114.8 (95%CI: 90.3, 143.9). We suspected that our surveillance may under-ascertain the true burden of disease, so we used location data from bacteraemic subjects and projected population estimates to calculate local sub-district incidence, then examined the impact of community level socio-demographic covariates as possible predictors of local sub-district incidence of pneumococcal and non-pneumococcal pathogenic bacteraemia. Geographic heterogeneity in incidence was marked with localised hotspots but ward level covariates apart from prison were not associated with pneumococcal bacteraemia incidence. Modelling suggests that the current sentinel surveillance system under-ascertains the true burden of disease. We outline a number of challenges to surveillance for pneumococcal disease in our low-resource setting. Subsequent surveillance in the vaccine era will have to account for geographic heterogeneity when evaluating population level indirect

    As the IC (integrated circuit) industry migrates to the System-on-Chip (SOC) era, a novel business model, the SOC design service (DS), is emerging. However, how to expand a firm’s innovation competences while satisfying multiple objectives including highest quality, lowest cost, and fastest time to market as well as most revenues for economics of scale are always problems for a design service firm. Therefore, attempts to expand the innovation competences, and thus the competitiveness, of latecomers in the SOC DS industry have already become the most critical issue facing the top managers of SOC design service firms. In this paper, a novel multiple attribute decision making (MADM) analytic framework based on the concept of competence set expansion, as well as MADM methods consisting with DEMATEL, ANP and multiple objective decision making (MODM) will be proposed in order to define a path for expanding a late-coming SOC DS firm’s innovation capabilities. An empirical study on expanding innovation competence sets, of a late-coming Taiwanese DS firm then will be presented.

    2015-01-01

    Background: The complexity of a medication regimen is related to the multiple characteristics of the prescribed regimen and can negatively influence the health outcomes of patients. Objective: To propose cut-off points in the complexity of pharmacotherapy to distinguish between patients with low and high complexities seen in a primary health care (PHC) setting to enable prioritization of patient management. Methods: This is a cross-sectional study, which included 517 adult and elderly patients, analyzing different cut-off points to define the strata of low and high pharmacotherapy complexities based on percentiles of the population evaluated. Data collection began with the solicitation of prescriptions, followed by a questionnaire that was administered by an interviewer. The complexity of a medication regimen was estimated from the Medication Regimen Complexity Index (MRCI). High complexity pharmacotherapy scores were analyzed from patient profiles, the use of health services, and pharmacotherapy. The criteria for subject inclusion in the sample population were as follows: inhabitant of the area covered by the municipality, 18 years or older, and being prescribed at least one drug during the collection period. Exclusion criteria at the time of collection were the use of any medication whose prescription was not available. All medications were accessed through the Primary Healthcare Service (PHS). Results: The median total pharmacotherapy complexity score was 8.5. High MRCI scores were correlated with age, medications taken with in the Brazilian PHS, having at least one potential drug-related problem, receiving up to eight years of schooling, number of medications and polypharmacy (five or more medicines), number of medical conditions, number of medical appointments, and number of cardiovascular diseases and endocrine metabolic diseases. We suggest different complexity tracks according to age (e.g., adult or elderly) that consider the pharmacotherapy and population

    Older adults benefit from unstructured, lifestyle-based activity that can be carried out in people's houses, neighbourhoods, and the built environment. Technological solutions may support physical activity and encourage wellbeing. To ensure such technology is suitable for, and usable by, older adults, it is crucial they are involved in all stages of design. Participatory design methodologies facilitate collaboration and engagement with potential users. We examine the suitability of participatory design for collaborating and engaging with older adults. Participatory design workshops were conducted with 33 older adults in the UK with the aim of designing mobile applications to support and promote physical activity and wellbeing in the built environment. As well as summarising the outcome of these workshops, the paper outlines several methodological issues relating to the suitability of participatory design for involving older adults in the technology design process.

    We have generated a series of variable-strength, constitutive, bacterial promoters that act predictably in different sequence contexts, span two orders of magnitude in strength and contain convenient sites for cloning and the introduction of downstream open-reading frames. Importantly, their design insulates these promoters from the stimulatory or repressive effects of many 5′- or 3′-sequence elements. We show that different promoters from our library produce constant relative levels of two different proteins in multiple genetic contexts. This set of promoters should be a useful resource for the synthetic-biology community. PMID:20843779

  17. Analysis of perceptual confusions between nine sets of consonant-vowel sounds in normal and dyslexic adults.

    It is widely accepted that most developmental dyslexics perform poorly on tasks which assess phonological awareness. One reason for this association might be that the early or "input" phonological representations of speech sounds are distorted or noisy in some way. We have attempted to test this hypothesis directly. In Experiment 1, we measured the confusions that adult dyslexics and controls made when they listened to nine randomly presented consonant-vowel (CV) segments [sequence: see text] under four conditions of increasing white noise masking. Subjects could replay stimuli and were under no obligation to respond quickly. Responses were selected with a computer mouse from a set of nine letter-strings, corresponding to the auditory stimuli, presented on a VDU. While the overall pattern of confusions made by dyslexics and controls was very similar for this stimulus set, dyslexics confused [sequence: see text] significantly more than did controls. In Experiment 2, subjects heard each stimulus once only and were forced to respond as quickly as possible. Under these timed conditions, the pattern of confusions made by dyslexics and controls was the same as before, but dyslexics took longer to respond than controls. The slower responses of dyslexics in Experiment 2 could have arisen because: (a) they were slower at processing the auditory stimuli than controls, (b) they had worse visual pattern memory for letter strings than controls, (c) they were slower than controls at using the computer mouse. In Experiments 3, 4 and 5 subjects carried out control tasks which eliminated each of these possibilities and confirmed that the results from the auditory tasks genuinely reflected subjects' speech perception. We propose that the fine structure of dyslexics' input phonological representations should be further explored with this confusion paradigm by using other speech sounds containing VCs, CCVs and VCCs.

    What is already known about this subject • Itraconazole is a triazole antifungal used in the treatment of allergic bronchopulmonary aspergillosis in patients with cystic fibrosis (CF). • The pharmacokinetic (PK) properties of this drug and its active metabolite have been described before, mostly in healthy volunteers. • However, only sparse information from case reports were available of the PK properties of this drug in CF patients at the start of our study. What this study adds • This study reports for the first time the population pharmacokinetic properties of itraconazole and a known active metabolite, hydroxy-itraconazole in adult patients with CF. • As a result, this study offers new dosing approaches and their pharmacoeconomic impact as well as a PK model for therapeutic drug monitoring of this drug in this patient group. • Furthermore, it is an example of a successful d-optimal design application in a clinical setting. Aim The primary objective of the study was to estimate the population pharmacokinetic parameters for itraconazole and hydroxy-itraconazole, in particular, the relative oral bioavailability of the capsule compared with solution in adult cystic fibrosis patients, in order to develop new dosing guidelines. A secondary objective was to evaluate the performance of a population optimal design. Methods The blood sampling times for the population study were optimized previously using POPT v.2.0. The design was based on the administration of solution and capsules to 30 patients in a cross-over study. Prior information suggested that itraconazole is generally well described by a two-compartment disposition model with either linear or saturable elimination. The pharmacokinetics of itraconazole and the metabolite were modelled simultaneously using NONMEM. Dosing schedules were simulated to assess their ability to achieve a trough target concentration of 0.5 mg ml−1. Results Out of 241 blood samples, 94% were taken within the defined optimal

    2010-01-01

    Objective: To examine how to screen for and establish a correct diagnosis of attention-deficit/hyperactivity disorder (ADHD) in adults and to identify the outcomes associated with untreated ADHD. Data Sources: PubMed was searched using the key words ADHD, adult, diagnosis, and primary care from the years 1999 to 2009. Study Selection: This search produced 50 publications. Data Extraction: Publications were screened for data specific to the diagnosis or management of adult patients with ADHD in the primary care setting. Data Synthesis: The estimated prevalence of ADHD in adults throughout the United States is 4.4% or approximately 10 million adults. Adults with ADHD by definition must experience impairment from the symptoms of ADHD in at least 2 areas of their life. Despite significant impairment, only 1 in 10 adults with ADHD have received ADHD treatment within the past year. Given the high rates of undertreatment, primary care physicians, who provide much of the general adult mental health care in the United States, are increasingly charged with making the diagnosis of ADHD in adults. ADHD symptoms are often masked by comorbid psychiatric conditions or patient adaptations such as choice of occupation. One of the ADHD assessment tools, a short 6-item screener, can simplify identification and management of ADHD in adults and help identify which patients may require further evaluation. Conclusions: Primary care physicians should consult with other members of the health care community such as psychiatrists and psychologists when necessary, but should also develop a level of comfort with diagnosing and treating ADHD.

    We present the results of the user studies of the CareMe prototype telecare service for supporting older adults with remote telecare services. The CareMe solution targets older adults who are capable of living independently and outside of a dedicated medical institution or a nursing home, but require occasional medical attention, and formal or informal care. The studies were conducted between November 2013 and March 2014 and followed the participatory design approach. The research questions focused on understanding the difference in the participatory design approach when older adults use paper prototypes vs interactive prototypes, and the difference when older adults use interactive prototypes with poor interface design vs interactive prototypes with rich interface design. In total, 45 older adults living in Slovenia participated in the field trial. They were retired, 32 of whom were nursing home residents and 13 were living independently at home. The study sample's age distribution was between 64 and 91 years. The analysis of the filed trial results indicated the importance of the factors that influence users' decision about how and when they use new technology, i.e., the perceived usefulness and the perceived ease-of-use. Main insights gained from the studies show, that it is very difficult to keep older people focused on the topics of discussion and that they have often difficulties to clearly present/express their ideas. Furthermore, abstract concepts, such as paper only prototypes proved to be challenging to cope with, whereas using real applications and services when trying out scenarios using interactive prototypes provided much better experience and feedback.

    Epigenetic alterations relate to various human diseases, and developing inhibitors of Kme regulatory proteins is considered to be a new frontier for drug discovery. We were inspired by the known multicyclic ligands, UNC669 and UNC926, which are the first reported small molecule ligands for a methyl-lysine binding domain. We hypothesized that reducing the conformational flexibility of the key amine moiety of UNC669 would result in a unique set of ligands. Twenty-five novel compounds containing a fused bi- or tricyclic amine or a spirocyclic amine were designed and synthesized. To gauge the potential of these amine-containing compounds to interact with Kme regulatory proteins, the compounds were screened against a panel of 24 protein methyltransferases. Compound 13 was discovered as a novel scaffold that interacts with SETD8 and could serve as a starting point for the future development of PKMT inhibitors. PMID:27528434

    2010-01-01

    Background Dental caries incidence in adults is similar to that in children and adolescents, but few caries preventive agents have been evaluated for effectiveness in adults populations. In addition, dentists direct fewer preventive services to their adult patients. Xylitol, an over-the-counter sweetener, has shown some potential as a caries preventive agent, but the evidence for its effectiveness is not yet conclusive and is based largely on studies in child populations. Methods/Design X-ACT is a three-year, multi-center, placebo controlled, double-blind, randomized clinical trial that tests the effects of daily use of xylitol lozenges versus placebo lozenges on the prevention of adult caries. The trial has randomized 691 participants (ages 21-80) to the two arms. The primary outcome is the increment of cavitated lesions. Discussion This trial should help resolve the overall issue of the effectiveness of xylitol in preventing caries by contributing evidence with a low risk of bias. Just as importantly, the trial will provide much-needed information about the effectiveness of a promising caries prevention agent in adults. An effective xylitol-based caries prevention intervention would represent an easily disseminated method to extend caries prevention to individuals not receiving caries preventive treatment in the dental office.

    One component of the recent obesity epidemic is the sedentary behaviour of children and adolescents e.g., use of video games consoles. The new generation of video games requires body movements and might thus increase activity. The aim of this study was to evaluate whether such games could have an effect on physical activity in obese adolescents in a clinical setting. Between March and May 2007 activity-promoting video games ("apvg") were offered to all 84 inpatients (aged 13-28 years) registered in a long-term rehabilitation programme on a voluntary base. Reasons for (non-)attendance were assessed. Frequency and duration of use of the activity-promoting video game sessions were documented. Furthermore, heart rate and activity counts during use of "apvg", endurance training, and strength training were measured. Of 84 inpatients, 51 used the "apvg" at least once (69%) over the study period. The median weekly use of the intervention was 27 min during the first week (range 0-182 min), declining to zero (range 0-74 min) in week four. Mean heart rate during the sessions (mean 115 bpm; 95% confidence interval 108-122 bpm) was similar to the heart rate during strength training (106 bpm; 101-112 bpm). The results indicate that the video games could have an impact on the activity of obese adolescents and young adults. However, as the interest in the devices seems to be too low the suitability of them for weight reduction programmes in young people cannot be ensured. PMID:20837400

  8. Challenges Caring for Adults With Congenital Heart Disease in Pediatric Settings: How Nurses Can Aid in the Transition.

    PubMed

    2016-08-01

    As surgery for complex congenital heart disease is becoming more advanced, an increasing number of patients are surviving into adulthood, yet many of these adult patients remain in the pediatric hospital system. Caring for adult patients is often a challenge for pediatric nurses, because the nurses have less experience and comfort with adult care, medications, comorbid conditions, and rehabilitation techniques. As these patients age, the increased risk of complications and comorbid conditions from their heart disease may complicate their care further. Although these patients are admitted on a pediatric unit, nurses can aid in promoting their independence and help prepare them to transition into the adult medical system. Nurses, the comprehensive medical teams, and patients' families can all effectively influence the process of preparing these patients for transition to adult care. PMID:27481810

    The segment erector is a key part of the shield machines for tunnel engineering. The available segment erectors are all of serial configuration which is suffering from the problems of low rigidity and accumulative motion errors. The current research mainly focuses on improving assembly accuracy and control performance of serial segment erectors. An innovative design method is proposed featuring motion group-decoupling, based on which a new type of segment erector is developed and investigated. Firstly, the segment installation manipulation is analyzed and decomposed into three motion groups that are decoupled. Then the type synthesis for the 4-DOF motion group is performed based on the general function( G F ) set theory and a new configuration of (1T⊕1R⊕1PS&3UPS) is attained according to the segment manipulation requirements. Consequently, the kinematic models are built and the reducibility and accuracy are analyzed. The dexterity is verified though numerical simulation and no singular points appear in the workspace. Finally, a positioning experiment is carried out by using the prototype developed in the lab that demonstrates a 13.1% improvement of positioning accuracy and the feasibility of the new segment erector. The presented group-decoupling design method is able to invent new type of hybrid segment erectors that avoid the accumulative motion error of erecting.

    2007-12-01

    Recent experiences in the action-oriented use of ergonomic checkpoints in different work settings are reviewed. The purpose is to know what features are useful for healthy work design adjusted to each local situation. Based on the review results, common features of ergonomic checkpoints used in participatory training programs for improving workplace conditions in small enterprises, construction sites, home work and agriculture in industrially developing countries in Asia are discussed. These checkpoints generally compile practical improvement options in a broad range of technical areas, such as materials handling, workstation design, physical environment and work organization. Usually, "action checklists" comprising the tiles of the checkpoints are used together. A clear focus is placed on readily applicable low-cost options. Three common features of these various checkpoints appear to be important. First, the checkpoints represent typical good practices in multiple areas. Second, each how-to section of these checkpoints presents simple improvements reflecting basic ergonomic principles. Examples of these principles include easy reach, fewer and faster transport, elbow-level work, coded displays, isolated or screened hazards and shared teamwork. Third, the illustrated checkpoints accompanied by corresponding checklists are used as group work tools in short-term training courses. Many practical improvements achieved are displayed in websites for inter-country work improvement networks. It is suggested to promote the use of locally adjusted checkpoints in various forms of participatory action-oriented training in small-scale workplaces and in agriculture particularly in industrially developing countries.

    This article reports a study of the physical design characteristics of a set of adult intensive care units (ICUs), built between 1993 and 2003. These ICUs were recognized as the best-practice examples by the Society of Critical Care Medicine, the American Association of Critical Care Nurses, and the American Institute of Architects. This study is based on a systematic analysis of the materials found on these ICUs in the booklet and videos jointly published by the above organizations in 2005. The study finds that most of these examples of best-practice adult ICUs have the following negative characteristics: (1) they are built as renovation projects with more health and safety hazards during construction; (2) most of them are mixed-service units with more safety and staffing problems; (3) the overall layout and the layout of staff work areas in these ICUs do not have any common design solutions for improved patient and staff outcomes; and (4) in these ICUs, family space is often located outside the unit, and family access to the patient room is restricted, even though family presence at the bedside may be important for improved patient outcomes. Some of these negative characteristics are offset by the following positive characteristics in most ICUs: (1) they have only private patient rooms for improved patient care, safety, privacy, and comfort; (2) most patient beds are freestanding for easy access to patients from all sides; (3) they have handwashing sinks and waste disposal facilities in the patient room for improved safety; and (4) most patient rooms have natural light to help patients with circadian rhythms. The article discusses, in detail, the implications of its findings, and the role of the ICU design community in a very complicated design context. PMID:17063097

    OBJECTIVES Currently there are no evidence-based recommendations regarding which fitness and strength tests to use for patients with childhood or adult idiopathic inflammatory myopathies (IIM). This hinders clinicians and researchers in choosing the appropriate fitness- or muscle strength-related outcome measures for these patients. Through a Delphi survey, we aimed to identify a candidate core-set of fitness and strength tests for children and adults with IIM. METHODS Fifteen experts participated in a Delphi survey that consisted of five stages to achieve a consensus. Using an extensive search of published literature and through the expertise of the experts, a candidate core-set based on expert opinion and clinimetric properties was developed. Members of the International Myositis Assessment and Clinical Studies Group (IMACS) were invited to review this candidate core-set during the final stage, which led to a final candidate core-set. RESULTS A core-set of fitness- and strength-related outcome measures was identified for children and adults with IIM. For both children and adults, different tests were identified and selected for maximal aerobic fitness, submaximal aerobic fitness, anaerobic fitness, muscle strength tests and muscle function tests. CONCLUSIONS The core-set of fitness and strength-related outcome measures provided by this expert consensus process will assist practitioners and researchers in deciding which tests to use in IIM patients. This will improve the uniformity of fitness and strength tests across studies, thereby facilitating the comparison of study results and therapeutic exercise program outcomes among patients with IIM.

    2014-01-01

    Background It is well documented that childhood abuse, neglect and household dysfunction are disproportionately present in the backgrounds of homeless adults, and that these experiences adversely impact child development and a wide range of adult outcomes. However, few studies have examined the cumulative impact of adverse childhood experiences on homeless adults with mental illness. This study examines adverse events in childhood as predictors of duration of homelessness, psychiatric and substance use disorders, and physical health in a sample of homeless adults with mental illness. Methods This study was conducted using baseline data from a randomized controlled trial in Vancouver, British Columbia for participants who completed the Adverse Childhood Experiences (ACE) scale at 18 months follow-up (n = 364). Primary outcomes included current mental disorders; substance use including type, frequency and severity; physical health; duration of homelessness; and vocational functioning. Results In multivariable regression models, ACE total score independently predicted a range of mental health, physical health, and substance use problems, and marginally predicted duration of homelessness. Conclusions Adverse childhood experiences are overrepresented among homeless adults with complex comorbidities and chronic homelessness. Our findings are consistent with a growing body of literature indicating that childhood traumas are potent risk factors for a number of adult health and psychiatric problems, particularly substance use problems. Results are discussed in the context of cumulative adversity and self-trauma theory. Trials registration This trial has been registered with the International Standard Randomized Control Trial Number Register and assigned ISRCTN42520374. PMID:24726046

    2010-01-01

    Objectives. Technology represents advances in knowledge that change the way humans perform tasks. Ideally, technology will make the task easier, more efficient, safer, or perhaps more pleasurable. Unfortunately, new technologies can sometimes make a task more difficult, slower, dangerous, or perhaps more frustrating. Older adults interact with a variety of technologies in the course of their daily activities and thus products should be designed to be used by people of varying ages. Methods. In this article, we provide an overview of what psychology has to offer to the design of technology—from understanding what people need, to identifying their preferences for design characteristics, and to defining their capabilities and limitations that will influence technology interactions. Results. We identify how research in the field of psychology and aging has advanced understanding of technology interactions and how research on technology interactions can inform theories of aging. Discussion. Design for aging involves understanding the unique capabilities and limitations of older adults; identifying their needs, preferences, and desires for technology in their lives; and involving them in the design process.

    Purpose To evaluate whether rehabilitation of muscle force or balance improves postural stability and quality of life (QoL), and whether self-administered training is comparable with guided training among older adults residing in an institutional setting. Patients and methods A randomized, prospective intervention study was undertaken among 55 elderly patients. Three intervention groups were evaluated: a muscle force training group; a balance and muscle force training group; and a self-administered training group. Each group underwent 1-hour-long training sessions, twice a week, for 3 months. Postural stability was measured at onset, after 3 months, and after 6 months. Time-domain-dependent body sway variables were calculated. The fall rate was evaluated for 3 years. General health related quality of life (HRQoL) was measured with a 15D instrument. Postural stability was used as a primary outcome, with QoL and falls used as secondary outcomes. Results Muscle force trainees were able to undertake training, progressing towards more strenuous exercises. In posturography, the number of spiky oscillations was reduced after training, and stationary fields of torque moments of the ankle increased, providing better postural stability in all groups; in particular, the zero crossing rate of weight signal and the number of low variability episodes in the stabilogram were improved after training. While no difference was found between different training groups in posturography outcomes, a reduction of fall rate was significant in only the guided training groups. A significant part of the variability of the QoL could be explained by the posturography outcome (46%). However, the outcome of training was associated with a reduced QoL. Conclusion Even moderate or severely demented residents could do exercises in five-person groups under the supervision of a physiotherapist. An improvement in postural stability was observed in all training groups, indicating that even self

    Background Many unhealthy dietary and physical activity habits that foster the development of obesity are established by the age of five. Presently, approximately 70 percent of children in the United States are currently enrolled in early childcare facilities, making this an ideal setting to implement and evaluate childhood obesity prevention efforts. We describe here the methods for conducting an obesity prevention randomized trial in the child care setting. Methods/design A randomized, controlled obesity prevention trial is currently being conducted over a three year period (2010-present). The sample consists of 28 low-income, ethnically diverse child care centers with 1105 children (sample is 60% Hispanic, 15% Haitian, 12% Black, 2% non-Hispanic White and 71% of caregivers were born outside of the US). The purpose is to test the efficacy of a parent and teacher role-modeling intervention on children’s nutrition and physical activity behaviors. . The Healthy Caregivers-Healthy Children (HC2) intervention arm schools received a combination of (1) implementing a daily curricula for teachers/parents (the nutritional gatekeepers); (2) implementing a daily curricula for children; (3) technical assistance with meal and snack menu modifications such as including more fresh and less canned produce; and (4) creation of a center policy for dietary requirements for meals and snacks, physical activity and screen time. Control arm schools received an attention control safety curriculum. Major outcome measures include pre-post changes in child body mass index percentile and z score, fruit and vegetable and other nutritious food intake, amount of physical activity, and parental nutrition and physical activity knowledge, attitudes, and beliefs, defined by intentions and behaviors. All measures were administered at the beginning and end of the school year for year one and year two of the study for a total of 4 longitudinal time points for assessment. Discussion Although few

    The only way to gain genuine expertise in Statistical Process Control (SPC) and the design of experiments (DOX) is with repeated practice, but not on canned problems with dead data sets. Rather, one must negotiate a wide variety of problems each with its own peculiarities and its own constantly changing data. The problems should not be of the type for which there is a single, well-defined answer that can be looked up in a fraternity file or in some text. The problems should match as closely as possible the open-ended types for which there is always an abundance of uncertainty. These are the only kinds that arise in real research, whether that be basic research in academe or engineering research in industry. To gain this kind of experience, either as a professional consultant or as an industrial employee, takes years. Vast amounts of money, not to mention careers, must be put at risk. The purpose here is to outline some realistic simulation-type lab exercises that are so simple and inexpensive to run that the students can repeat them as often as desired at virtually no cost. Simulations also allow the instructor to design problems whose outcomes are as noisy as desired but still predictable within limits. Also the instructor and the students can learn a great deal more from the postmortum conducted after the exercise is completed. One never knows for sure what the true data should have been when dealing only with real life experiments. To add a bit more realism to the exercises, it is sometimes desirable to make the students pay for each experimental result from a make-believe budget allocation for the problem.

    Abstract Introduction: Telemedicine has become a prevalent topic in recent years, and several telemedicine systems have been proposed; however, such systems are an unsuitable fit for the daily requirements of users. Materials and Methods: The system proposed in this study was developed as a set-top box integrated with the Android™ (Google, Mountain View, CA) operating system to provide a convenient and user-friendly interface. The proposed system can assist with family healthcare management, telemedicine service delivery, and information exchange among hospitals. To manage the system, a novel type of hybrid cloud architecture was also developed. Results: Updated information is stored on a public cloud, enabling medical staff members to rapidly access information when diagnosing patients. In the long term, the stored data can be reduced to improve the efficiency of the database. Conclusions: The proposed design offers a robust architecture for storing data in a homecare system and can thus resolve network overload and congestion resulting from accumulating data, which are inherent problems in centralized architectures, thereby improving system efficiency.

    Difficulty with social competence is a core deficit of autism spectrum disorder. Research on typically developing children and children with disabilities, in general, suggests the adult talk received in the classroom is related to their social development. The aims of this study were to examine (1) the types and amounts of adult talk children with autism spectrum disorder are exposed to in the preschool classroom and (2) the associations between child characteristics (e.g. language), activity area, and adult talk. Kontos' Teacher Talk classification was used to code videos approximately 30 min in length of 73 children with autism spectrum disorder (ages 3-5) in inclusive classrooms (n = 33) during center time. The results indicated practical/personal assistance was the most common type of adult talk coded, and behavior management talk least often coded. Child characteristics (i.e. age and autism severity) and activity area were found to be related to specific types of adult talk. Given the findings, implications for future research are discussed.

    Background The current landscape of a rapidly aging population accompanied by multiple chronic conditions presents numerous challenges to optimally support the complex needs of this group. Mobile health (mHealth) technologies have shown promise in supporting older persons to manage chronic conditions; however, there remains a dearth of evidence-informed guidance to develop such innovations. Objectives The purpose of this study was to conduct a scoping review of current practices and recommendations for designing, implementing, and evaluating mHealth technologies to support the management of chronic conditions in community-dwelling older adults. Methods A 5-stage scoping review methodology was used to map the relevant literature published between January 2005 and March 2015 as follows: (1) identified the research question, (2) identified relevant studies, (3) selected relevant studies for review, (4) charted data from selected literature, and (5) summarized and reported results. Electronic searches were conducted in 5 databases. In addition, hand searches of reference lists and a key journal were completed. Inclusion criteria were research and nonresearch papers focused on mHealth technologies designed for use by community-living older adults with at least one chronic condition, or health care providers or informal caregivers providing care in the home and community setting. Two reviewers independently identified articles for review and extracted data. Results We identified 42 articles that met the inclusion criteria. Of these, described innovations focused on older adults with specific chronic conditions (n=17), chronic conditions in general (n=6), or older adults in general or those receiving homecare services (n=18). Most of the mHealth solutions described were designed for use by both patients and health care providers or health care providers only. Thematic categories identified included the following: (1) practices and considerations when designing m

    In this work, a new two-dimensional optics design method is proposed that enables the coupling of three ray sets with two lens surfaces. The method is especially important for optical systems designed for wide field of view and with clearly separated optical surfaces. Fermat's principle is used to deduce a set of functional differential equations fully describing the entire optical system. The presented general analytic solution makes it possible to calculate the lens profiles. Ray tracing results for calculated 15th order Taylor polynomials describing the lens profiles demonstrate excellent imaging performance and the versatility of this new analytic design method.

    2010-01-01

    Background People living with HIV (PLHIV) sometimes experience discrimination. There is little understanding of the causes, forms and consequences of this stigma in Islamic countries. This qualitative study explored perceptions and experiences of PLHIV regarding both the quality of healthcare and the attitudes and behaviours of their healthcare providers in the Islamic Republic of Iran. Methods In-depth, semi-structured interviews were held with a purposively selected group of 69 PLHIV recruited from two HIV care clinics in Tehran. Data were analyzed using the content analysis approach. Results and discussion Nearly all participants reported experiencing stigma and discrimination by their healthcare providers in a variety of contexts. Participants perceived that their healthcare providers' fear of being infected with HIV, coupled with religious and negative value-based assumptions about PLHIV, led to high levels of stigma. Participants mentioned at least four major forms of stigma: (1) refusal of care; (2) sub-optimal care; (3) excessive precautions and physical distancing; and (4) humiliation and blaming. The participants' healthcare-seeking behavioural reactions to perceived stigma and discrimination included avoiding or delaying seeking care, not disclosing HIV status when seeking healthcare, and using spiritual healing. In addition, emotional responses to perceived acts of stigma included feeling undeserving of care, diminished motivation to stay healthy, feeling angry and vengeful, and experiencing emotional stress. Conclusions While previous studies demonstrate that most Iranian healthcare providers report fairly positive attitudes towards PLHIV, our participants' experiences tell a different story. Therefore, it is imperative to engage both healthcare providers and PLHIV in designing interventions targeting stigma in healthcare settings. Additionally, specialized training programmes in universal precautions for health providers will lead to stigma reduction

    2016-01-01

    The Study of Heart and Renal Protection (SHARP) found that treatment with ezetemibe and low-dose simvastatin reduced the incidence of major atherosclerotic events in patients with kidney disease. Due to the paucity of evidence-based interventions that lower cardiovascular morbidity in this high-risk population, the SHARP trial will likely have a large impact on clinical practice. However, applying the results of clinical trials conducted in select populations to the care of individual patients in real-world settings can be fraught with difficulty. This is especially true when caring for older adults with complex comorbidity and limited life expectancy. These patients are often excluded from clinical trials, frequently have competing health priorities, and may be less likely to benefit and more likely to be harmed by medications. We discuss key considerations in applying the results of the SHARP trial to the care of older adults with CKD in real-world clinical settings using guiding principles set forth by the American Geriatrics Society's Expert Panel on the Care of Older Adults with Multimorbidity. Using this schema, we emphasize the importance of evaluating trial results in the unique context of each patient's goals, values, priorities, and circumstances. PMID:26709060

    Objectives This paper describes research designed to specify complementary therapies used among older adults by obtaining daily use data and the specific purposes for use. Design Two-hundred African American and white participants completed a baseline interview and up to six sets of three daily-diary interviews at monthly intervals. Results Participants provided retrospective information on complementary therapy use, and information on the use of therapies for specific symptoms experienced across 3,070 person days. Retrospective information indicated that most participants used complementary therapies (e.g., 85.0% used home remedies in the past year). The use of complementary or other therapies and the number of days the therapies were used varied for specific symptoms. For example, home remedies were used on 86 (9.1%) of the 944 person days for which joint pain was reported. Discussion The daily-diary design provides detailed information for delineating how elders include complementary and other therapies in their health self-management. PMID:20937796

    Medical school curricula are undergoing transformational change in response to calls for integrating content across courses and years to enable better retention and application and for individualizing learning to meet the diverse backgrounds and thus differing needs of students. To address the related teaching challenges, faculty can employ solid principles of adult learning and instructional design and use teaching strategies that stimulate different learning styles. We developed laboratory sessions that follow a learner-centered instructional design model we refer to as "PLHET," reflecting the steps of preparing, linking, hooking, engaging, and transferring learning, and also applied teaching strategies that reflect Kolb's four styles of learning (accommodative, divergent, assimilative, and convergent). We utilized a group learning format to promote active learning, teamwork, and self-direction. Preliminary data based on student surveys of laboratory activity show positive responses. In the future, we will test the hypothesis that this design will improve medical students' performance. PMID:23081886

    The aim was to design sterile biodegradable microparticulate drug delivery systems based on poly(dl-lactide) (PLA) and poly(ε-caprolactone) (PCL) and containing ivermectin (IVM), an antiparasitic drug, for subcutaneous administration in dogs. The drug delivery system should: (i) ensure a full 12-month protection upon single dose administration; (ii) be safe with particular attention regarding IVM dosage and its release, in order to prevent over dosage side effects. This preliminary work involves: polymer selection, evaluation of the effects of γ-irradiation on the polymers and IVM, investigation and set up of suitable microparticle preparation process and parameters, IVM-loaded microparticles in vitro release evaluation. Results of gel permeation chromatography analysis on the irradiated polymers and IVM mixtures showed that combination of IVM with the antioxidant α-tocopherol (TCP) reduces the damage extent induced by irradiation treatment, independently on the polymer type. Solvent evaporation process was successfully used for the preparation of PLA microparticles and appropriately modified; it was recognized as suitable for the preparation of PCL microparticles. Good process yields were achieved ranging from 76.08% to 94.72%; encapsulation efficiency was between 85.76% and 91.25%, independently from the polymer used. The type of polymer and the consequent preparation process parameters affected microparticle size that was bigger for PCL microparticles (480-800 µm) and solvent residual that was >500 ppm for PLA microparticles. In vitro release test showed significantly faster IVM release rates from PCL microparticles, with respect to PLA microparticles, suggesting that a combination of the polymers could be used to obtain the suitable drug release rate.

    A poor appetite in older adults is an important determinant of reduced food intake and undernutrition. Food preferences may influence food intake. The aim of this study was to investigate food preferences of older adults with a poor appetite and compare these with preferences of older adults with a good appetite. Older adults (n = 349, aged 65-101 years) in nursing/residential care homes, hospitals or at home receiving home care participated in a computer-based forced-choice food preference assessment. Self-reported appetite in the past week was classified as 'good' or 'poor' using a validated instrument. Food preferences were determined by counting the relative frequency of choices for food images according to 11 dichotomous categories: high/low 1) protein; 2) fat; 3) carbohydrates; 4) fiber; 5) variation; and 6) animal/vegetarian proteins; 7) sweet/savory taste; 8) solid/liquid texture; 9) dairy/non-dairy; with/without 10) sauce or 11) color variation. Specific food preferences in participants with a poor appetite were identified by one-sample t-tests comparing frequencies to the expected value of 48. Preference differences between those with a good and a poor appetite were analyzed using GLM adjusting for confounders. The results showed that older adults with a poor appetite (n = 113; 32.4%) preferred variation (51.6 vs. 48, P < 0.001), color variation (55.9 vs. 48, P < 0.01), non-dairy (53.0 vs. 48, P < 0.001), high-fiber (51.8 vs. 48, P < 0.05), and solid texture (53.5 vs. 48, P < 0.05). Participants with a poor appetite had a higher frequency score for variation than participants with a good appetite (51.6 vs. 48.5, P < 0.001). In conclusion, older adults with a poor appetite may have specific food preferences. Their preference for variation differs from those with a good appetite. These results may be used to develop meals that are preferred by older adults with poor appetite in order to increase food intake and prevent

    Background The Canadian International Polar Year (IPY) program made it possible to undertake much needed health research in 3 jurisdictions within the Canadian Inuit Nunangat (homeland) over a 2-year period: Inuvialuit Settlement Region (ISR), Nunavut Territory, and Nunatsiavut. Design The Adult Inuit Health Survey (IHS) was a cross-sectional survey and provides baseline data upon which future comparisons can be made for prospectively assessing factors leading to the progression of chronic diseases among Canadian Inuit. With the help of the Canadian Coast Guard Ship Amundsen, which was equipped with research and laboratory facilities, 33 coastal communities were visited; land survey teams visited 3 inland communities. Results The Adult IHS succeeded in obtaining important baseline information concerning the health status and living conditions of 2,595 adults living in ISR, Nunavut and Nunatsiavut. Conclusion Information from this survey will be useful for future comparisons and the opportunity to link with the International Inuit Cohort, a follow-up evaluation, and for the development of future health policies and public health interventions.

    2008-08-01

    Novel single electron transistor (SET) read-out circuit designs are described. The circuits use a silicon SET interfaced to a CMOS voltage mode or current mode comparator to obtain a digital read-out of the state of the qubit. The design assumes standard submicron (0.35 um) CMOS SOI technology using room temperature SPICE models. Implications and uncertainties related to the temperature scaling of these models to 100mK operation are discussed. Using this technology, the simulations predict a read-out operation speed of approximately Ins and a power dissipation per cell as low as 2nW for single-shot read-out, which is a significant advantage over currently used radio frequency SET (RF-SET) approaches.

    BACKGROUND Cardiovascular diseases are the most common cause of death in Iran. Moreover, periodontal diseases are very common in our country. In this study, we have designed a standardized questionnaire for evaluating knowledge, attitude, and practice (KAP) of Iranian adult patients with cardiovascular diseases about oral health. METHODS For designing and standardizing a self-administered questionnaire, we performed a cross-sectional pilot study on 51 cases with periodontal complaints. A dentist carried out the physical examination to determine oral health indicators. Twelve experts and ten lay people of the target population answered questions about validity. Cronbach’s alpha, factor analysis, and Pearson correlation coefficients were used in the analysis. RESULTS The cases of this pilot study were middle aged, with moderate financial and health status, but low oral health and educational level. Debris score was correlated with all other physical exam findings except decay, missing, and filled (DMF). Reliability was 0.826 according to Cronbach’s alpha score. Face validity was higher than 80%. Content validities of the whole of the questionnaire were 85.98% for clarity, 78.05% for relevancy, 85.16% for simplicity, and 82.32% for consistency of each question with the question set. Factor analysis showed that 15 components explain 74% of the total variance. CONCLUSION This questionnaire is culturally adjusted and appropriate for our community, valid and reliable, and sufficiently estimates the variance of the oral health status. It can be used as a standard tool in further studies in adult population of the Iranian middle aged patients with low level of education and moderate socioeconomic status. PMID:24575138

    Felyx is currently under development and is the latest evolution of a generalised High Resolution Diagnostic Data Set system funded by ESA. It draws on previous prototype developments and experience in the GHRSST, Medspiration, GlobColour and GlobWave projects. In this paper, we outline the design and implementation of the system, and illustrate using the Ocean Colour demonstration activities. Felyx is fundamentally a tool to facilitate the analysis of EO data: it is being developed by IFREMER, PML and Pelamis. It will be free software written in python and javascript. The aim is to provide Earth Observation data producers and users with an opensource, flexible and reusable tool to allow the quality and performance of data streams from satellite, in situ and model sources to be easily monitored and studied. New to this project, is the ability to establish and incorporate multi-sensor match-up database capabilities. The systems will be deployable anywhere and even include interaction mechanisms between the deployed instances. The primary concept of Felyx is to work as an extraction tool. It allows for the extraction of subsets of source data over predefined target areas(which can be static or moving). These data subsets, and associated metrics, can then be accessed by users or client applications either as raw files or through automatic alerts. These data can then be used to generate periodic reports or be used for statistical analysis and visualisation through a flexible web interface. Felyx can be used for subsetting, the generation of statistics, the generation of reports or warnings/alerts, and in-depth analyses, to name a few. There are many potential applications but important uses foreseen are: * monitoring and assessing the quality of Earth observations (e.g. satellite products and time series) through statistical analysis and/or comparison with other data sources * assessing and inter-comparing geophysical inversion algorithms * observing a given phenomenon

  3. Diamonds in the rough: key performance indicators for reticles and design sets

    Ackmann, Paul

    2008-10-01

    The discussion on reticle cost continues to raise questions by many in the semiconductor industry. The diamond industry developed a method to judge and grade diamonds. [1, 11] The diamond-marketing tool of "The 4Cs of Diamonds" and other slogans help explain the multiple, complex variables that determine the value of a particular stone. Understanding the critical factors of Carat, Clarity, Color, and Cut allows all customers to choose a gem that matches their unique desires. I apply the same principles of "The 4Cs of Diamonds" to develop an analogous method for rating and tracking reticle performance. I introduced the first 3Cs of reticle manufacturing during my BACUS presentation panel at SPIE in February 2008. [2] To these first 3Cs (Capital, Complexity, and Content), I now add a fourth, Cycle time. I will look at how our use of reticles changes by node and use "The 4Cs of Reticles" to develop the key performance indicators (KPI) that will help our industry set standards for evaluating reticle technology. Capital includes both cost and utilization. This includes tools, people, facilities, and support systems required for building the most critical reticles. Tools have highest value in the first two years of use, and each new technology node will likely increase the Capital cost of reticles. New technologies, specifications, and materials drive Complexity for reticles, including smaller feature size, increased optical proximity correction (OPC), and more levels at sub-wavelength. The large data files needed to create finer features require the use of the newest tools for writing, inspection, and repair. Content encompasses the customer's specifications and requirements, which the mask shop must meet. The specifications are critical because they drive wafer yield. A clear increase of the number of masking levels has occurred since the 90 nm node. Cycle time starts when the design is finished and lasts until the mask house ships the reticle to the fab.

    Young adults in South Africa are at the epicenter of the HIV epidemic. The prevalence of HIV among young people in the province of KwaZulu-Natal (KZN) is particularly high. This study characterizes inkwari (Zulu word for raves or weekend-long parties) in eThekwini District, KZN and explored how these place-based dynamics shape the risk environment for the young adult attendees. In 2011, 13 qualitative interviews were conducted with men and women between 18 and 30 years-old who reported unprotected sex with at least one casual partner in the prior 3 months and attended an inkwari in the same time period. Interviews were analyzed using qualitative content analysis. Nine key informant interviews helped to triangulate these data. Five women and eight men were interviewed and the mean age was 25 years (SD 3.24). Ten reported meeting a sexual partner at an inkwari. Inkwari were characterized as sexualized settings with limited adult supervision. Participants attended inkwari to socialize with peers, use drugs and alcohol, and meet sexual partners. Sexual and physical violence also occurred at inkwari. Given the convergence of social, sexual, and substance- using networks at inkwari, further inquiry is needed to determine how this place may potentiate HIV transmission risk in an endemic setting.

    The Study of Exercise and Nutrition in Older Rhode Islanders (SENIOR) Project II is an intervention study to promote the maintenance of both exercise and healthful eating in older adults. It is the second phase of an earlier study, SENIOR Project I, that originally recruited 1,277 community-dwelling older adults to participate in behavior-specific interventions designed to increase exercise and/or fruit and vegetable consumption. The general theoretical framework for this research is the Transtheoretical Model (TTM) of Health Behavior Change. The current intervention occurs over a 48-month period, using a manual, newsletters, and phone coaching calls. Annual assessments collect standardized data on behavioral outcomes (exercise and diet), TTM variables (stage of change and self-efficacy), psychosocial variables (social support, depression, resilience, and life satisfaction), physical activity and functioning (SF-36, Up and Go, Senior Fitness Test, and disability assessment), cognitive functioning (Trail Making Test and Forward and Backward Digit Span), physical measures (height, weight, and waist circumference), and demographics. The SENIOR Project II is designed to answer the following question as its primary objective: (1) Does an individualized active-maintenance intervention with older adults maintain greater levels of healthful exercise and dietary behaviors for four years, compared to a control condition? In addition, there are two secondary objectives: (2) What are the psychosocial factors associated with the maintenance of health-promoting behaviors in the very old? and (3) What are the effects of the maintenance of health-promoting behaviors on reported health outcomes, psychosocial measures, anthropometrics, and cognitive status?

    Peng, Wei

    2009-03-01

    This article reports the development and evaluation of a computer game (RightWay Café) as a special medium to promote a healthy diet for young adults. Structural features of computer games, such as interactive tailoring, role playing, the element of fun, and narrative, were operationalized in the RightWay Café game to afford behavior rehearsal in a safe and entertaining way. Theories such as the health belief model, social cognitive theory, and theory of reasoned action guided the content design of the game to influence mediators of behavior change, including self-efficacy, perceived benefits, perceived barriers, and behavior change intention. A randomized controlled evaluation study with pretest, posttest, and follow-up design demonstrated that this game was effective in teaching nutrition and weight management knowledge and increasing people's self-efficacy and perceived benefits of healthy eating, as well as their intention to be on a healthy diet. Limited long-term effects were also found: participants in the game-playing group had greater self-efficacy than participants in the control group after 1 month. This study validates the computer game-based approach to health promotion for young adults. Limitations and implications are also discussed. PMID:19280455

    Background Performing multiple blood culture sets simultaneously is a standard blood culture methodology, although it is often difficult to distinguish true bacteremia from contamination when only one of several blood culture sets is positive. This study clarified the relationship between the number of positive blood culture sets and clinical significance in patients with positive blood culture. Methods Patients aged 18 years and over with at least 1 positive blood culture were enrolled. Positive blood culture episodes were categorized from clinical records as true bacteremia, contamination, or unknown clinical significance. The associations among episodes of true bacteremia, isolated bacteria, the number of positive blood culture sets from among the performed sets, and the clinical background of patients were analyzed. Results Among a total of 407 episodes, 262, 67 and 78 were true bacteremia, contamination and unknown clinical significance, respectively. The positive predictive values (PPVs) of 1 out of 1, 1 out of 2 and 2 out of 2 positive sets in cases of Staphylococcus aureus, were 81.3%, 50% and 100% respectively; those in cases of coagulase-negative Staphylococci were 20.5%, 10.8% and 63.5%, respectively. Almost all cases of Escherichia coli, Pseudomonas aeruginosa, Klebsiella species and Candida species were true bacteremia. The probability of true bacteremia was strongly associated with recent surgery in multivariate analysis (P < 0.05). Conclusion The probability of true bacteremia based on the number of positive culture sets from among the performed sets varies by microorganism. Therefore, PPVs calculated using this method may help physicians distinguish true bacteremia from contamination. PMID:25901103

    2015-11-01

    This paper deals with the problem of designing an iterative learning control algorithm for discrete linear systems using repetitive process stability theory. The resulting design produces a stabilizing output feedback controller in the time domain and a feedforward controller that guarantees monotonic convergence in the trial-to-trial domain. The results are also extended to limited frequency range design specification. New design procedure is introduced in terms of linear matrix inequality (LMI) representations, which guarantee the prescribed performances of ILC scheme. A simulation example is given to illustrate the theoretical developments.

    The long-term survival of patients with adult high-grade glioma (HGG) remains poor, but for those who do live longer functional status and neurocognitive ability may be influenced by residual or recurrent tumour, or treatment-related complications. The aim of this review was to examine the current literature regarding the quality of life and experience of patients living longer with adult HGG and their caregivers, with a view to understanding the burden of treatment on patient abilities and deficits over time. Medline, PsychINFO and CINAHL databases were searched for the core concept of HGG in combination with an aspect of quality of long-term survival. Key findings of the 12 included studies were identified and synthesised thematically. There is a paucity of dedicated studies which have investigated the experiences of this cohort. The strength of existing literature is limited by the systematic exclusion of the poorest functioning patients and the under-representation of caregiver perspectives. Discrepancies in how patients view their quality of life were highlighted, despite consistent findings of significant physical and functional impairment. This review confirmed the presence of important differences between patient and caregiver views regarding patient abilities following treatment. Caregiver burden was found to be high, due to multiple dynamic and relentless stressors. The true experience of patients living longer with adult HGG and their caregivers remains unclear, particularly for patients with poorer neurocognitive and functional outcomes. Further research is required to clarify and replicate findings, explore discrepancies between patient and caregiver views, and to specifically investigate how caregiver needs and experiences may evolve over time.

  10. Using Mutual Information Criterion to Design an Efficient Phoneme Set for Chinese Speech Recognition

    NASA Astrophysics Data System (ADS)

    Zhang, Jin-Song; Hu, Xin-Hui; Nakamura, Satoshi

    Chinese is a representative tonal language, and it has been an attractive topic of how to process tone information in the state-of-the-art large vocabulary speech recognition system. This paper presents a novel way to derive an efficient phoneme set of tone-dependent units to build a recognition system, by iteratively merging a pair of tone-dependent units according to the principle of minimal loss of the Mutual Information (MI). The mutual information is measured between the word tokens and their phoneme transcriptions in a training text corpus, based on the system lexical and language model. The approach has a capability to keep discriminative tonal (and phoneme) contrasts that are most helpful for disambiguating homophone words due to lack of tones, and merge those tonal (and phoneme) contrasts that are not important for word disambiguation for the recognition task. This enables a flexible selection of phoneme set according to a balance between the MI information amount and the number of phonemes. We applied the method to traditional phoneme set of Initial/Finals, and derived several phoneme sets with different number of units. Speech recognition experiments using the derived sets showed its effectiveness.

    2014-07-01

    We present innovative, immersed grating based optical designs for the SMO (Spectrograph Main Optics) module of the Mid-infrared E-ELT Imager and Spectrograph, METIS. The immersed grating allows a significant reduction of SMO volume compared to conventional echelle grating designs, because the diffraction takes place in high refractive index silicon. Additionally, using novel optimization techniques and technical solutions in silicon micromachining offered by the semiconductor industry, further improvements can be achieved. We show optical architectures based on compact, double-pass Three Mirror Anastigmat (TMA) designs, which appear advantageous in terms of one or several of the following: optical performance, reduction of volume, ease of manufacturing and testing. We explore optical designs, where the emphasis is put on manufacturability and we investigate optical solutions, where the ultimate goal is the highest possible optical performance. These novel, silicon immersed grating based design concepts are applicable for future earth and space based spectrometers.

    Objectives: Tuberculosis (TB) is estimated to be the leading cause of HIV-related deaths globally. However, since HIV-associated TB frequently remains unascertained, we systematically reviewed autopsy studies to determine the true burden of TB at death. Methods: We systematically searched Medline and Embase databases (to end 2013) for literature reporting on health facility-based autopsy studies of HIV-infected adults and/or children in resource-limited settings. Using forest plots and random-effects meta-analysis, we summarized the TB prevalence found at autopsy and used meta-regression to explore variables associated with autopsy TB prevalence. Results: We included 36 eligible studies, reporting on 3237 autopsies. Autopsy TB prevalence was extremely heterogeneous (range 0–64.4%), but was markedly higher in adults [pooled prevalence 39.7%, 95% confidence interval (CI) 32.4–47.0%] compared to children (pooled prevalence 4.5%, 95% CI 1.7–7.4%). Post-mortem TB prevalence varied by world region, with pooled estimates in adults of 63.2% (95% CI 57.7–68.7%) in South Asia (n = 2 studies); 43.2% (95% CI 38.0–48.3) in sub-Saharan Africa (n = 9 studies); and 27.1% (95% CI 16.0–38.1%) in the Americas (n = 5 studies). Autopsy prevalence positively correlated with contemporary estimates of national TB prevalence. TB in adults was disseminated in 87.9% (82.2–93.7%) of cases and was considered the cause of death in 91.4% (95% CI 85.8–97.0%) of TB cases. Overall, TB was the cause of death in 37.2% (95% CI 25.7–48.7%) of adult HIV/AIDS-related deaths. TB remained undiagnosed at death in 45.8% (95% CI 32.6–59.1%) of TB cases. Conclusions: In resource-limited settings, TB accounts for approximately 40% of facility-based HIV/AIDS-related adult deaths. Almost half of this disease remains undiagnosed at the time of death. These findings highlight the critical need to improve the prevention, diagnosis and treatment of HIV-associated TB globally. PMID

    2016-01-01

    This article describes a potential way of counseling emerging adults from a life design perspective to construct a self that could enable them to be agents of both their own development and the development of others. Theoretical issues relating to a dynamic, developmental and systems framework of the understanding of wellbeing are described and the process involved is delineated. The research design was qualitative and comprised case studies. Six participants who subscribed to the definition of “emerging adults” and were comparatively representative of the ethnic diversity of South Africa, were selected purposively from a group of individuals who applied for career counseling in a private practice context. The intervention involved life design counseling and occurred over a period of 6 weeks. Information related to participants' self-construction was gathered using qualitative techniques, including the Career Interest Profile, the Career Construction Interview, a timeline, video clips, a collage, and semi-structured interviews. Following the intervention, the participants revealed heightened insights with regard to aspects of their sense of a relational-moral self. Results indicated that life design counseling could enhance elaborative personal development (enhancing self-awareness and reaping the benefits of developing an improved relational-moral self) and the promotion of an awareness of the importance to promote social justice in work-related contexts.

    2014-01-01

    Background Few studies have designed and tested the use of continuous quality improvement approaches in community based substance use treatment settings. Little is known about the feasibility, costs, efficacy, and sustainment of such approaches in these settings. Methods/Design A group-randomized trial using a modified stepped wedge design is being used. In the first phase of the study, eight programs, stratified by modality (residential, outpatient) are being randomly assigned to the intervention or control condition. In the second phase, the initially assigned control programs are receiving the intervention to gain additional information about feasibility while sustainment is being studied among the programs initially assigned to the intervention. Discussion By using this design in a pilot study, we help inform the field about the feasibility, costs, efficacy and sustainment of the intervention. Determining information at the pilot stage about costs and sustainment provides value for designing future studies and implementation strategies with the goal to reduce the time between intervention development and translation to real world practice settings.

  2. Enumerating a Diverse Set of Building Designs Using Discrete Optimization: Preprint

    SciTech Connect

    Hale, E.; Long, N.

    2010-08-01

    Numerical optimization is a powerful method for identifying energy-efficient building designs. Automating the search process facilitates the evaluation of many more options than is possible with one-off parametric simulation runs. However, input data uncertainties and qualitative aspects of building design work against standard optimization formulations that return a single, so-called optimal design. This paper presents a method for harnessing a discrete optimization algorithm to obtain significantly different, economically viable building designs that satisfy an energy efficiency goal. The method is demonstrated using NREL's first-generation building analysis platform, Opt- E-Plus, and two example problems. We discuss the information content of the results, and the computational effort required by the algorithm.

  3. Sample entropy reveals high discriminative power between young and elderly adults in short fMRI data sets

    PubMed Central

    Sokunbi, Moses O.

    2014-01-01

    Some studies have placed Sample entropy on the same data length constraint of 10m–20m (m: pattern length) as approximate entropy, even though Sample entropy is largely independent of data length and displays relative consistency over a broader range of possible parameters (r, tolerance value; m, pattern length; N, data length) under circumstances where approximate entropy does not. This is particularly erroneous for some fMRI experiments where the working data length is less than 100 volumes (when m = 2). We therefore investigated whether Sample entropy is able to effectively discriminate fMRI data with data length, N less than 10m (where m = 2) and r = 0.30, from a small group of 10 younger and 10 elderly adults, and the whole cohort of 43 younger and 43 elderly adults, that are significantly (p < 0.001) different in age. Ageing has been defined as a loss of entropy; where signal complexity decreases with age. For the small group analysis, the results of the whole brain analyses show that Sample entropy portrayed a good discriminatory ability for data lengths, 85 ≤ N ≤ 128, with an accuracy of 85% at N = 85 and 80% at N = 128, at q < 0.05. The regional analyses show that Sample entropy discriminated more brain regions at N = 128 than N = 85 and some regions common to both data lengths. As data length, N increased from 85 to 128, the noise level decreased. This was reflected in the accuracy of the whole brain analyses and the number of brain regions discriminated in the regional analyses. The whole brain analyses suggest that Sample entropy is relatively independent of data length, while the regional analyses show that fMRI data with length of 85 volumes is consistent with our hypothesis of a loss of entropy with ageing. In the whole cohort analysis, Sample entropy discriminated regionally between the younger and elderly adults only at N = 128. The whole cohort analysis at N = 85 was indicative of the ageing process but this indication was not significant (p

  4. Design of the Prevention of Adult Caries Study (PACS): A randomized clinical trial assessing the effect of a chlorhexidine dental coating for the prevention of adult caries

    PubMed Central

    2010-01-01

    Background Dental caries is one of the primary causes of tooth loss among adults. It is estimated to affect a majority of Americans aged 55 and older, with a disproportionately higher burden in disadvantaged populations. Although a number of treatments are currently in use for caries prevention in adults, evidence for their efficacy and effectiveness is limited. Methods/Design The Prevention of Adult Caries Study (PACS) is a multicenter, placebo-controlled, double-blind, randomized clinical trial of the efficacy of a chlorhexidine (10% w/v) dental coating in preventing adult caries. Participants (n = 983) were recruited from four different dental delivery systems serving four diverse communities, including one American Indian population, and were randomized to receive either chlorhexidine or a placebo treatment. The primary outcome is the net caries increment (including non-cavitated lesions) from baseline to 13 months of follow-up. A cost-effectiveness analysis also will be considered. Discussion This new dental treatment, if efficacious and approved for use by the Food and Drug Administration (FDA), would become a new in-office, anti-microbial agent for the prevention of adult caries in the United States.

    2016-01-01

    Background: We report a randomized controlled clinical trial of neurofeedback therapy intervention for ADHD/ADD in adults. We focus on internal mechanics of neurofeedback learning, to elucidate the primary role of cortical self-regulation in neurofeedback. We report initial results; more extensive analysis will follow. Methods: Trial has two phases: intervention and follow-up. The intervention consisted of neurofeedback treatment, including intake and outtake measurements, using a waiting-list control group. Treatment involved ~40 h-long sessions 2–5 times per week. Training involved either theta/beta or sensorimotor-rhythm regimes, adapted by adding a novel “inverse-training” condition to promote self-regulation. Follow-up (ongoing) will consist of self-report and executive function tests. Setting: Intake and outtake measurements were conducted at University of Helsinki. Treatment was administered at partner clinic Mental Capital Care, Helsinki. Randomization: We randomly allocated half the sample then adaptively allocated the remainder to minimize baseline differences in prognostic variables. Blinding: Waiting-list control design meant trial was not blinded. Participants: Fifty-four adult Finnish participants (mean age 36 years; 29 females) were recruited after screening by psychiatric review. Forty-four had ADHD diagnoses, 10 had ADD. Measurements: Symptoms were assessed by computerized attention test (T.O.V.A.) and self-report scales, at intake and outtake. Performance during neurofeedback trials was recorded. Results: Participants were recruited and completed intake measurements during summer 2012, before assignment to treatment and control, September 2012. Outtake measurements ran April-August 2013. After dropouts, 23 treatment and 21 waiting-list participants remained for analysis. Initial analysis showed that, compared to waiting-list control, neurofeedback promoted improvement of self-reported ADHD symptoms, but did not show transfer of learning to T

    What models can effectively guide the creation of eHealth and mHealth technologies? This paper describes the use of the NIATx model as a framework for the user-centered design of a new technology for older adults. The NIATx model is a simple framework of process improvement based on the following principles derived from an analysis of decades of research from various industries about why some projects fail and others succeed: (1) Understand and involve the customer; (2) fix key problems; (3) pick an influential change leader; (4) get ideas from outside the field; (5) use rapid-cycle testing. This paper describes the use of these principles in technology development, the strengths and challenges of using this approach in this context, and lessons learned from the process. Overall, the NIATx model enabled us to produce a user-focused technology that the anecdotal evidence available so far suggests is engaging and useful to older adults. The first and fourth principles were especially important in developing the technology; the fourth proved the most challenging to use. PMID:27025985

    Objectives To evaluate functional outcomes, care needs and cost-efficiency of specialist rehabilitation for a multicentre cohort of inpatients with complex neurological disability, comparing different diagnostic groups across 3 levels of dependency. Design A multicentre cohort analysis of prospectively collected clinical data from the UK Rehabilitation Outcomes Collaborative (UKROC) national clinical database, 2010–2015. Setting All 62 specialist (levels 1 and 2) rehabilitation services in England. Participants Working-aged adults (16–65 years) with complex neurological disability. Inclusion criteria: all episodes with length of stay (LOS) 8–400 days and complete outcome measures recorded on admission and discharge. Total N=5739: acquired brain injury n=4182 (73%); spinal cord injury n=506 (9%); peripheral neurological conditions n=282 (5%); progressive conditions n=769 (13%). Intervention Specialist inpatient multidisciplinary rehabilitation. Outcome measures Dependency and care costs: Northwick Park Dependency Scale/Care Needs Assessment (NPDS/NPCNA). Functional independence: UK Functional Assessment Measure (UK Functional Independence Measure (FIM)+FAM). Cost-efficiency: (1) time taken to offset rehabilitation costs by savings in NPCNA-estimated costs of ongoing care, (2) FIM efficiency (FIM gain/LOS days), (3) FIM+FAM efficiency (FIM+FAM gain/LOS days). Patients were analysed in 3 groups of dependency. Results Mean LOS 90.1 (SD 66) days. All groups showed significant reduction in dependency between admission and discharge on all measures (paired t tests: p<0.001). Mean reduction in ‘weekly care costs’ was greatest in the high-dependency group at £760/week (95% CI 726 to 794)), compared with the medium-dependency (£408/week (95% CI 370 to 445)), and low-dependency (£130/week (95% CI 82 to 178)), groups. Despite longer LOS, time taken to offset the cost of rehabilitation was 14.2 (95% CI 9.9 to 18.8) months in the high-dependency group, compared

  9. Designing Websites for Displaying Large Data Sets and Images on Multiple Platforms

    The desire to build websites to analyze and display ever increasing amounts of scientific data and images pushes for web site designs which utilize large displays, and to use the display area as efficiently as possible. Yet, scientists and users of their data are increasingly wishing to access these websites in the field and on mobile devices. This results in the need to develop websites that can support a wide range of devices and screen sizes, and to optimally use whatever display area is available. Historically, designers have addressed this issue by building two websites; one for mobile devices, and one for desktop environments, resulting in increased cost, duplicity of work, and longer development times. Recent advancements in web design technology and techniques have evolved which allow for the development of a single website that dynamically adjusts to the type of device being used to browse the website (smartphone, tablet, desktop). In addition they provide the opportunity to truly optimize whatever display area is available. HTML5 and CSS3 give web designers media query statements which allow design style sheets to be aware of the size of the display being used, and to format web content differently based upon the queried response. Web elements can be rendered in a different size, position, or even removed from the display entirely, based upon the size of the display area. Using HTML5/CSS3 media queries in this manner is referred to as "Responsive Web Design" (RWD). RWD in combination with technologies such as LESS and Twitter Bootstrap allow the web designer to build web sites which not only dynamically respond to the browser display size being used, but to do so in very controlled and intelligent ways, ensuring that good layout and graphic design principles are followed while doing so. At the University of Alaska Fairbanks, the Alaska Satellite Facility SAR Data Center (ASF) recently redesigned their popular Vertex application and converted it from a

    An experiment is proposed which will compare the effectiveness of individual versus group brainstorming in addressing difficult, real world challenges. Previous research into electronic brainstorming has largely been limited to laboratory experiments using small groups of students answering questions irrelevant to an industrial setting. The proposed experiment attempts to extend current findings to real-world employees and organization-relevant challenges. Our employees will brainstorm ideas over the course of several days, echoing the real-world scenario in an industrial setting. The methodology and hypotheses to be tested are presented along with two questions for the experimental brainstorming sessions. One question has been used in prior work and will allow calibration of the new results with existing work. The second question qualifies as a complicated, perhaps even wickedly hard, question, with relevance to modern management practices.

    Universal Design is a very simple idea that is based on complex decisions and it involves user satisfaction during performance of activities and socially inclusive interaction. Generally, the design guidelines for application in architecture requires that both students and professionals explore their imagination about the situations in which the design of a certain building becomes more pleasant and inviting than simply accessible to the needs of people with permanent and temporary disabilities. In this paper, the aim is to discuss peculiar aspects in the design of a three storey building that make it special. The result of technical solutions create environments that are not restricted to the boundaries of a site. It also encompasses the street, the crossing, the corner square and traffic signals and marks beside some accessible parking areas. The building design is an academic exploration of potential usage to an actual site. It belongs to an institution for social network of people aging above sixty-five year old. PMID:27534307

    Sub-Saharan Africa is disproportionately burdened by intestinal helminth and human immunodeficiency virus (HIV)-1 infection. Recent evidence suggests detrimental immunologic effects from concomitant infection with the two pathogens. Few studies, however, have assessed the prevalence of and predictors for intestinal helminth infection among HIV-1–infected adults in urban African settings where HIV infection rates are highest. We collected and analyzed sociodemographic and parasitologic data from 297 HIV-1–infected adults (mean age = 31.1 years, 69% female) living in Lusaka, Zambia to assess the prevalence and associated predictors of helminth infection. We found at least one type of intestinal helminth in 24.9% of HIV-infected adults. Thirty-nine (52.7%) were infected with Ascaris lumbricoides, and 29 (39.2%) were infected with hookworm. More than 80% were light-intensity infections. A recent visit to a rural area, food shortage, and prior history of helminth infection were significant predictors of current helminth status. The high helminth prevalence and potential for adverse interactions between helminths and HIV suggests that helminth diagnosis and treatment should be part of routine HIV care. PMID:16222025

    The purpose of this study was to design a systematic program of fitness training that enhances physical fitness of mentally retarded adults in sheltered workshops. The first phase of the study was a six-month program conducted by physical education graduate students while the second phase was four months in duration and led by workshop employees. Instructors followed a manual containing 48 lesson plans that were specifically prepared for mentally retarded participants. The physical fitness programs were evaluated using the Canadian Standardized Test of Fitness. MANOVA results revealed that both the six-month and four-month programs increased the physical fitness of the mentally retarded workers, although cardiovascular endurance improved only as a function of the four-month program.

    The current study investigated the effects of goal setting and performance feedback on Curriculum Based Measurement in Written Expression (CBM-WE). This two-study investigation examined the utility of the intervention using two different delivery mechanisms. In Study 1, fourth grade students (n=114) were provided both with (a) feedback from their teachers regarding their performance on CBM-WE probes and (b) new weekly goals or no feedback and goals, once a week for a ten-week intervention period. Study 2 examined the effects of this intervention with a sample of fifth grade students (n=106) when feedback and individual goals were provided by peers within their classrooms twice weekly over the course of eight weeks compared to a practice only control condition. Results in both studies indicated that students receiving the goal setting and feedback intervention performed significantly higher on production-dependent writing indices post-intervention than control groups (ES=.12-.28). Implications regarding the usefulness of goal setting and feedback utilizing CBM procedures are discussed. PMID:27268571

Express 20, 5576-5585 (2012)] is extended in this work to the three-dimensional case, enabling the coupling of three ray sets with two free-form lens surfaces. Fermat's principle is used to deduce additional sets of functional differential equations which make it possible to calculate the lens surfaces. Ray tracing simulations demonstrate the excellent imaging performance of the resulting free-form lenses described by more than 100 coefficients. PMID:22565708

    At the outset of the design for the Defense Waste Processing Facility (DWPF) it was determined to complete over 70 percent of the more than 7000 drawings on a Computer Aided Drafting and Design (CADD) system. This ambitious goal required the development of an integrated data base for plant design software systems to service a multi-discipline, engineering and management environment for the complex one-of-a-kind mega project. The implementation involved extensive training, special accounting and security provisions to meet QA requirements. It was found to be effective to train engineers as well as operators so that technical personnel could have direct access to the drawing files. This was particularly useful when designing and laying out close tolerance equipment in remotely maintained cells where clearances are critical. It was also beneficial to have the terminals located in the same areas as the engineering staff. Background drawings were maintained by one discipline and used as a reference file by the other disciplines. This reduced the chances of interferences and insured that the latest revisions were in use. 2 figs.

    Summary Background Southern Africa has a high incidence of bacterial meningitis in adults, often associated with HIV co-infection. Even with appropriate antibiotic therapy, mortality exceeds 50% and is not improved with corticosteroids. Glycerol adjuvant therapy reduced mortality and long-term morbidity (deafness) in bacterial meningitis in children and is being promoted. If similarly effective in adults, glycerol would provide a cheap, available adjuvant therapy in Africa. Methods Following a dose-finding study, we conducted a randomised double-blind placebo-controlled trial of oral glycerol in adults with bacterial meningitis. Patients with clinical and CSF findings suggestive of bacterial meningitis were randomised either to glycerol or an equivalent volume of sugar solution. The primary outcome was mortality at 40 days with secondary outcomes including disability and mortality restricted to pneumococcal disease. Findings 75ml glycerol QDS was best tolerated and was used for the main study. 265 patients were randomised to receive glycerol or placebo. The trial was stopped early on the advice of the Data and Safety Monitoring Board (DSMB) following a planned interim analysis. Mortality by day 40 was 61/125 (49%) in the placebo and 86/136 (69%) in the glycerol arms, Adjusted Odds Ratio 2·4 (95% CI 1·3-4·2 p0·003). There was no benefit from glycerol for death and disability by day 40 by intention to treat or in predefined subgroups. Two serious adverse events occurred possibly due to study drug. Interpretation Oral glycerol therapy did not improve mortality in adults with bacterial meningitis and cannot be recommended as a suitable adjuvant therapy in resource-poor settings with a high HIV prevalence.

    An analysis of the efficacy of a picture archiving and communication system (PACS) in the surgical domain was undertaken at the Baltimore Veterans Affairs Medical Center. Interviews with surgeons and staff were conducted and supplemented by direct radiologist observation in the operating room (OR) and surgical outpatient clinic to determine patterns of routine clinical PACS use, levels of satisfaction both within and outside of the OR, and perceptions of the relative efficacy of the system in comparison to film. These data as well as suggestions from the surgical staff members were used to make recommendations for specific modifications in PACS design and operation to improve the current system and to help prescribe design improvements for future PAC systems. A high level of satisfaction with the system was found and the use of PACS was favored over film by a majority of surgeons and their staff. Findings of this study suggest that the design of a hospital-wide PAC system must have the flexibility to accommodate the specific requirements of a wide variety of end-users in their unique hospital environments.

    My case study explored Filipino secondary students' and teachers' experiences with technology research, project-based pedagogy. The study was conducted to examine the nature of a Technology Research (TR) Curriculum, and how it mediates non-Western students' learning, and interest in technology-based careers. The context for my study is Philippine Science High School's (PSHS) TR program wherein students outline a proposal, design an experiment or a device, and implement their design to address a real world problem. My data sources included semi-structured interviews of 27 students and 2 teachers; participant observations of classroom and group activities, teacher-student consultations, and Science-Technology Fair presentations; TR curriculum documents; and researcher journal logs. My examination of curriculum documents revealed that since the 1960s, the Philippine government has implemented specialized educational programs, such as the PSHS Science/Technology Streaming and TR programs, to support Filipino youth interested in science and technology courses and careers. Data analyses showed that the TR program provided a rich, practical learning environment where 'doing technology design' blended with 'doing science inquiry'. The TR activities enhanced student understanding of science and technology; helped them integrate and apply knowledge and skills learned from other school subjects; encouraged them to be creative, problem-solvers; and helped develop their lifelong learning skills. Students recognized that TR teachers adopted alternative instructional strategies that prompted students to adopt more active roles in their learning. Research findings revealed that student interest in pursuing technology-related careers was supported by their participation in the streaming and the TR programs. Data also showed that Filipino cultural practices mediated student learning, and career decision-making. My research findings suggest that present notions of scientific inquiry

    We studied the transmission routes of human T-cell lymphotropic virus type I (HTLV-I) within families of 82 Brazilian patients diagnosed with adult T-cell leukaemia/lymphoma (ATL). Diagnosis of ATL in 43 male and 39 female patients was based on clinical and laboratory criteria of T-cell malignancy and detection of HTLV-I monoclonal integration. Samples were tested for HTLV antibodies and infection was confirmed as HTLV-I by Western Blot and/or polymerase chain reaction (PCR) assays. Overall 26/37 (70%) of mothers, 24/37 (65%) of wives, 8/22 (36%) of husbands, 34/112 (30%) of siblings and 10/82 (12%) offspring were HTLV-I infected. In 11 ATL patients, mothers were repeatedly HTLV-I seronegative, but HTLV-I pol or tax sequences were detected in 2 out of 6 cases tested by PCR. ATL patients with seronegative mothers related the following risk factors for HTLV-I infection: 6 were breast-fed by surrogate mothers with unknown HTLV-I status, 4 had a sexually promiscuous behaviour and 1 had multiple blood transfusions at a young age. Familial aggregation of ATL and other HTLV-I associated diseases such as HTLV-I myelopathy (HAM/TSP) and or uveitis, ATL in sibling pairs or in multiple generations was seen in 9 families. There were 6 families with ATL and TSP sibling pairs. In 3 families at least one parent had died with lymphoma or presenting neurological diseases and 2 offspring with ATL. Further to the extent of vertical and horizontal transmission of HTLV-I infection within ATL families, our results demonstrate that mothers who provide surrogate breast-milk appear to be an important source of HTLV-I transmission and ATL development in Brazil.

    In the Coastal Plains region of the United States, the hard setting subsoil layer of Norfolk soils results in low water holding capacity and nutrient retention, which often limits root development. In this region, the Norfolk soils are under intensive crop production that further depletes nutrients and reduces organic carbon (C). Incorporation of pyrolyzed organic residues or "biochars" can provide an alternative recalcitrant C source. However, biochar quality and effect can be inconsistent and different biochars react differently in soils. We hypothesized that addition of different designer biochars will have variable effects on biomass and nutrient uptake of winter wheat. The objective of this study was to investigate the effects of designer biochars on biomass productivity and nutrient uptake of winter wheat (Triticum aestivum L.) in a Norfolk's hard setting subsoil layer. Biochars were added to Norfolk's hard setting subsoil layer at the rate of 40 Mg ha(-1). The different sources of biochars were: plant-based (pine chips, PC); animal-based (poultry litter, PL); 50:50 blend (50% PC:50% PL); 80:20 blend (80% PC:20% PL); and hardwood (HW). Aboveground and belowground biomass and nutrient uptake of winter wheat varied significantly (p⩽0.0001) with the different designer biochar applications. The greatest increase in the belowground biomass of winter wheat over the control was from 80:20 blend of PC:PL (81%) followed by HW (76%), PC (59%) and 50:50 blend of PC:PL (9%). However, application of PL resulted in significant reduction of belowground biomass by about 82% when compared to the control plants. The average uptake of P, K, Ca, Mg, Na, Al, Fe, Cu and Zn in both the aboveground and belowground biomass of winter wheat varied remarkably with biochar treatments. Overall, our results showed promising significance for the treatment of a Norfolk's hard setting subsoil layer since designer biochars did improve both aboveground/belowground biomass and nutrient uptake

  5. Designing a Successful Bidding Strategy Using Fuzzy Sets and Agent Attitudes

    NASA Astrophysics Data System (ADS)

    Ma, Jun; Goyal, Madhu Lata

    To be successful in a multi-attribute auction, agents must be capable of adapting to continuously changing bidding price. This chapter presents a novel fuzzy attitude-based bidding strategy (FA-Bid), which employs dual assessment technique, i.e., assessment of multiple attributes of the goods as well as assessment of agents' attitude (eagerness) to procure an item in automated auction. The assessment of attributes adapts the fuzzy sets technique to handle uncertainty of the bidding process as well use heuristic rules to determine the attitude of bidding agents in simulated auctions to procure goods. The overall assessment is used to determine a price range based on current bid, which finally selects the best one as the new bid.

The Sacramento River Basin is one of 60 study units located throughout the United States that has been scheduled for study as part of the National Water-Quality Assessment Program. The Sacramento River Basin is the most important source of freshwater in California. Water quality studies in the Sacramento River Basin study unit focus on the Sacramento Valley because it is here that the principal uses of water and potential impacts on water quality occur. Investigative activities include a network of surface water sites, where water chemistry and aquatic biological sampling are done, and a variety of ground water studies. In addition, investigations of the cycling and distribution of volatile organic compounds in the urban environment and the distribution of total and methyl mercury in the Sacramento River and tributaries will be completed.

    Background There is growing interest in investigating acceptance of robots, which are increasingly being proposed as one form of assistive technology to support older adults, maintain their independence, and enhance their well-being. In the present study, we aimed to observe robot-acceptance in older adults, particularly subsequent to a 1-month direct experience with a robot. Subjects and methods Six older adults with mild cognitive impairment (MCI) and five cognitively intact healthy (CIH) older adults were recruited. Participants interacted with an assistive robot in the Living Lab once a week for 4 weeks. After being shown how to use the robot, participants performed tasks to simulate robot use in everyday life. Mixed methods, comprising a robot-acceptance questionnaire, semistructured interviews, usability-performance measures, and a focus group, were used. Results Both CIH and MCI subjects were able to learn how to use the robot. However, MCI subjects needed more time to perform tasks after a 1-week period of not using the robot. Both groups rated similarly on the robot-acceptance questionnaire. They showed low intention to use the robot, as well as negative attitudes toward and negative images of this device. They did not perceive it as useful in their daily life. However, they found it easy to use, amusing, and not threatening. In addition, social influence was perceived as powerful on robot adoption. Direct experience with the robot did not change the way the participants rated robots in their acceptance questionnaire. We identified several barriers to robot-acceptance, including older adults’ uneasiness with technology, feeling of stigmatization, and ethical/societal issues associated with robot use. Conclusion It is important to destigmatize images of assistive robots to facilitate their acceptance. Universal design aiming to increase the market for and production of products that are usable by everyone (to the greatest extent possible) might help to

This project is developing a series of instructional packages that are based on a different instructional model - authentic instruction. The instructional development model used to create these packages is also different. Instead of using the traditional five stage linear, sequential model based on behavioral learning theory, the project uses the recursive, reflective design and development model (R2D2) that is based on cognitive learning theory, particularly the social constructivism of Vygotsky, and an epistemology based on critical theory. Using alternative instructional and instructional development theories, the result of the summer faculty fellowship is LiteraCity, a multimedia adult literacy instructional package that is a simulation of finding and applying for a job. The program, which is about 120 megabytes, is distributed on CD-ROM.

    The role of Systems and Product Architects is increasingly important for the development of modern products and services that are sustainable, innovative, and successful. This paper shows that competences in integration in product and systems design have to be a key part of these architect's competence profiles. Capitalizing on results from extensive research in the optimization of product development, it points out that the integration of all stakeholders from the earliest development phases is a fundamental need to be able to take into account all requirements and constraints imposed on both hardware and software products and systems. It draws the conclusion that the key stakeholders in product and system development processes need to have skills that enable this way of doing integrated development.

    Biomedical researchers have become increasingly aware of the limitations of conventional 2-dimensional tissue cell culture systems, including coated Petri dishes, multi-well plates and slides, to fully address many critical issues in cell biology, cancer biology and neurobiology, such as the 3-D microenvironment, 3-D gradient diffusion, 3-D cell migration and 3-D cell-cell contact interactions. In order to fully understand how cells behave in the 3-D body, it is important to develop a well-controlled 3-D cell culture system where every single ingredient is known. Here we report the development of a 3-D cell culture system using a designer peptide nanofiber scaffold with mouse adult neural stem cells. We attached several functional motifs, including cell adhesion, differentiation and bone marrow homing motifs, to a self-assembling peptide RADA16 (Ac-RADARADARADARADA-COHN2). These functionalized peptides undergo self-assembly into a nanofiber structure similar to Matrigel. During cell culture, the cells were fully embedded in the 3-D environment of the scaffold. Two of the peptide scaffolds containing bone marrow homing motifs significantly enhanced the neural cell survival without extra soluble growth and neurotrophic factors to the routine cell culture media. In these designer scaffolds, the cell populations with β-Tubulin+, GFAP+ and Nestin+ markers are similar to those found in cell populations cultured on Matrigel. The gene expression profiling array experiments showed selective gene expression, possibly involved in neural stem cell adhesion and differentiation. Because the synthetic peptides are intrinsically pure and a number of desired function cellular motifs are easy to incorporate, these designer peptide nanofiber scaffolds provide a promising controlled 3-D culture system for diverse tissue cells, and are useful as well for general molecular and cell biology.

    Summary Short sleep has been associated with cardiovascular risk. The aim of this study was to determine the impact of short-term sleep restriction on lipid profiles and resting blood pressure factors in young, normal weight individuals (14 men, 13 women). Participants were randomized to 5 nights of either habitual (9 h) or short (4 h) sleep in a crossover design separated by a 3 wk washout period. There was no sleep x day interaction on lipid profile and blood pressure. Short-term sleep restriction does not alter lipid profiles and resting blood pressure in healthy, normal weight individuals. The association between short sleep and increased cardiovascular risk reported in the epidemiological literature may be the result of long-term sleep restriction and poor lifestyle choices.

    This study demonstrates that containment of municipal and hazardous waste in arid and semiarid environments can be accomplished effectively without traditional, synthetic materials and complex, multi-layer systems. This research demonstrates that closure covers combining layers of natural soil, native plant species, and climatic conditions to form a sustainable, functioning ecosystem will meet the technical equivalency criteria prescribed by the U. S. Environmental Protection Agency. In this study, percolation through a natural analogue and an engineered cover is simulated using the one-dimensional, numerical code UNSAT-H. UNSAT-H is a Richards. equation-based model that simulates soil water infiltration, unsaturated flow, redistribution, evaporation, plant transpiration, and deep percolation. This study incorporates conservative, site-specific soil hydraulic and vegetation parameters. Historical meteorological data are used to simulate percolation through the natural analogue and an engineered cover, with and without vegetation. This study indicates that a 3-foot (ft) cover in arid and semiarid environments is the minimum design thickness necessary to meet the U. S. Environmental Protection Agency-prescribed technical equivalency criteria of 31.5 millimeters/year and 1 x 10{sup -7} centimeters/second for net annual percolation and average flux, respectively. Increasing cover thickness to 4 or 5 ft results in limited additional improvement in cover performance.

    To investigate the effects of the diagnoses of borderline personality disorder (BPD) and major depressive disorder (MDD), together with reasons for client non-compliance with therapy tasks, on mental health workers' helping, empathy and anger reactions. Utilizing a 2 x 2 x 2 factorial design, mental health nurses were asked to read a series of vignettes and complete a 15-item rating scale for helping, empathy and anger reactions to each of the vignettes. Eight clinical vignettes were constructed and contained a combination of controllable/uncontrollable and stable/unstable attributional dimensions for service users who failed to complete a therapy task. The diagnoses of BPD and MDD were added to the vignettes to determine whether diagnoses affected alliance factors. A total of 26 mental health workers participated in the study and there were main effects for those workers to be angrier when causes were perceived as due to controllable factors; to be more helpful to service users' with a diagnosis of MDD; and less helpful when causes were perceived to be due to stable factors. Results show some support for Weiner's model of helping behaviour. It is suggested that there is an important role to explore the attributions of mental health workers working with service users with BPD. A role for case conceptualization is discussed to facilitate therapeutic engagement with service users with a diagnosis of BPD. PMID:17244003

    Patient navigation programs have shown to be effective across multiple settings in guiding patients through the care delivery process. Limited experience and literature exist, however, for such programs in rural and resource-constrained environments. Patients living in such settings frequently have low health literacy and substantially lower social status than their providers. They typically have limited experiences interfacing with formalized healthcare systems, and, when they do, their experience can be unpleasant and confusing. At a district hospital in rural far-western Nepal, we designed and implemented a patient navigation system that aimed to improve patients' subjective care experience. First, we hired and trained a team of patient navigators who we recruited from the local area. Their responsibility is exclusively to demonstrate compassion and to guide patients through their care process. Second, we designed visual cues throughout our hospital complex to assist in navigating patients through the buildings. Third, we incorporated the patient navigators within the management and communications systems of the hospital care team, and established standard operating procedures. We describe here our experiences and challenges in designing and implementing a patient navigator program. Such patient-centered systems may be relevant at other facilities in Nepal and globally where patient health literacy is low, patients come from backgrounds of substantial marginalization and disempowerment, and patient experience with healthcare facilities is limited.

    Objectives The United States Department of Agriculture's Child and Adult Care Food Program (CACFP) provides meals and snacks to low-income children in child care. This study compared nutrition and physical activity practices and policies as well as the overall nutrition and physical activity environments in a sample of CACFP and non-CACFP child care settings. Methods A random stratified sample of 350 child care settings in a large Midwestern city and its suburbs, was mailed a survey on obesity prevention practices and policies concerning menu offerings, feeding practices, nutrition and physical activity education, activity levels, training, and screen time. Completed surveys were obtained from 229 of 309 eligible child care settings (74.1 % response rate). Chi square tests were used to compare practices and policies in CACFP and non-CACFP sites. Poisson and negative binomial regression were used to examine associations between CACFP and total number of practices and policies. Results Sixty-nine percent of child care settings reported CACFP participation. A significantly higher proportion of CACFP sites reported offering whole grain foods daily and that providers always eat the same foods that are offered to the children. CACFP sites had 1.1 times as many supportive nutrition practices as non-CACFP sites. CACFP participation was not associated with written policies or physical activity practices. Conclusions for Practice There is room for improvement across nutrition and physical activity practices and policies. In addition to food reimbursement, CACFP participation may help promote child care environments that support healthy nutrition; however, additional training and education outreach activities may be needed.

    Recent studies on workflow processes in hospital settings have shown that, since the introduction of EHRs, care-providers spend an increasing amount of their time on documentation rather than on bedside patient care. In order to improve the bedside work process and facilitate bedside documentation, we are developing an evidence-based mobile app for healthcare providers. In this paper, we present a tailored software development life cycle model that we created and validated during the design and development of this smartphone application. PMID:27577371

    Objectives. Translating efficacious interventions into practice within community settings is a major public health challenge. We evaluated the effects of 2 evidence-based physical activity interventions on self-reported physical activity and related outcomes in midlife and older adults. Methods. Four community-based organizations implemented Active Choices, a 6-month, telephone-based program, and 5 implemented Active Living Every Day, a 20-week, group-based program. Both programs emphasize behavioral skills necessary to become more physically active. Participants completed pretest and posttest surveys. Results. Participants (n=838) were aged an average of 68.4 ±9.4 years, 80.6% were women, and 64.1% were non-Hispanic White. Seventy-two percent returned posttest surveys. Intent-to-treat analyses found statistically significant increases in moderate-to-vigorous physical activity and total physical activity, decreases in depressive symptoms and stress, increases in satisfaction with body appearance and function, and decreases in body mass index. Conclusions. The first year of Active for Life demonstrated that Active Choices and Active Living Every Day, 2 evidence-based physical activity programs, can be successfully translated into community settings with diverse populations. Further, the magnitudes of change in outcomes were similar to those reported in the efficacy trials. PMID:16735619

    A full-custom design of an element selection algorithm, named as Split-set Data Weighted Averaging (SDWA) is implemented in 90nm CMOS Technology Synopsys Library. SDWA is applied in seven unit elements (3-bit) using a thermometer-coded input. Split-set DWA is an improved DWA algorithm which caters the requirement for randomization along with long-term equal element usage. Randomization and equal element-usage improve the spectral response of the unit elements due to higher Spurious-free dynamic range (SFDR) and without significantly degrading signal-to-noise ratio (SNR). Since a full-custom, the design is brought to transistor-level and the chip custom layout is also provided, having a total area of 0.3mm2, a power consumption of 0.566 mW, and simulated at 50MHz clock frequency. On this implementation, SDWA is successfully derived and improved by introducing a register at the output that suppresses the jitter introduced at the final stage due to switching loops and successive delays.

    Sleep problems are prevalent among older adults, often persist untreated, and are predictive of health detriments. Given the limitations of conventional treatments, non-pharmacological treatments such as mindfulness-based interventions (MBIs) are gaining popularity for sleep ailments. However, nothing is yet known about the impact of MBIs on sleep in older adults with prodromal sleep disturbances. This article details the design and methodology of a 6-week parallel-group RCT calibrated to test the treatment effect of the Mindful Awareness Practices (MAPs) program versus sleep hygiene education for improving sleep quality, as the main outcome, in older adults with prodromal sleep disturbances. Older adults with current sleep disturbances will be recruited from the urban Los Angeles community. Participants will be randomized into two standardized treatment conditions, MAPs and sleep hygiene education. Each condition will consist of weekly 2-hour group-based classes over the course of the 6-week intervention. The primary objective of this study is to determine if mindfulness meditation practice as engaged through the MAPs program leads to improved sleep quality relative to sleep hygiene education in older adults with prodromal sleep disturbances.

    Drug use is associated with increased sexual risk behaviors. We examined whether decreases in drug use risk are associated with reduction in HIV-related sex risk behaviors among adults. Data was from a cohort of participants (n = 574) identified by drug use screening in a randomized trial of brief intervention for drug use in an urban primary care setting. Inverse probability of treatment weighted (IPTW) logistic regression models were used to examine the relationship between decreases in drug use risk and sex-related HIV risk behavior reduction from study entry to six months. Weights were derived from propensity score modeling of decreases in drug use risk as a function of potential confounders. Thirty seven percent of the study participants (213/574) reported a decrease in drug use risk, and 7% (33/505) reported decreased sex-related HIV risk behavior at the six-month follow-up point. We did not detect a difference in reduction of risky sexual behaviors for those who decreased drug use risk (unadjusted: OR 1.32, 95% CI 0.65-2.70; adjusted OR [AOR] 1.12, 95% CI 0.54-2.36). Adults who screened positive for high drug use risk had greater odds of reducing sex risk behavior in unadjusted analyses OR 3.71, 95% CI 1.81-7.60; but the results were not significant after adjusting for confounding AOR 2.50, 95% CI 0.85-7.30). In this primary care population, reductions in HIV sex risk behaviors have complex etiologies and reductions in drug use risk do not appear to be an independent predictor of them. PMID:27570734

    Interventions to improve water quality, particularly when deployed at the household level, are an effective means of preventing endemic diarrheal disease, a leading cause of mortality and morbidity in the developing world. We assessed the microbiologic performance of a novel water treatment device designed for household use in low-income settings. The device employs a backwashable hollow fiber ultrafiltration cartridge and is designed to mechanically remove enteric pathogenic bacteria, viruses, and protozoan cysts from drinking water without water pressure or electric power. In laboratory testing through 20,000 L (approximately 110% of design life) at moderate turbidity (15 nephelometric turbidity unit [NTU]), the device achieved log(10) reduction values of 6.9 for Escherichia coli, 4.7 for MS2 coliphage (proxy for enteric pathogenic viruses), and 3.6 for Cryptosporidium oocysts, thus exceeding levels established for microbiological water purifiers. With periodic cleaning and backwashing, the device produced treated water at an average rate of 143 mL/min (8.6 L/hour) (range 293 to 80 mL/min) over the course of the evaluation. If these results are validated in field trials, the deployment of the unit on a wide scale among vulnerable populations may make an important contribution to public health efforts to control intractable waterborne diseases.

    Loss of balance and falling are critical concerns for older adults. Physical activity can improve balance and decrease the risk of falling. The purpose of this study was to evaluate a simple, low-cost exercise program for community-dwelling older adults. Sixteen senior adults were evaluated using the Senior Fitness Test for measures of functional strength, aerobic endurance, dynamic balance and agility, and flexibility. In addition, measures of height, weight, resting blood pressure, blood lipids, and cognitive function were obtained. Participants then attended a 10-week exercise class including stretching, strengthening, and balance-training exercises. At the completion of the program, significant improvements were observed in tests measuring dynamic balance and agility, lower and upper extremity strength, and upper extremity flexibility. The results indicate that exercise programs such as this are an effective, low-cost solution to improving health and factors that affect falling risk among older adults. PMID:15995265

    Purpose The Study of Progression of Adult Nearsightedness (SPAN) is a 5-year observational study to determine the risk factors associated with adult myopia progression. Candidate risk factors include: a high proportion of time spent performing near tasks, performing near tasks at a close distance, high accommodative convergence/accommodation (AC/A) ratio, and high accommodative lag. Methods Subjects between 25 and 35 years of age, with at least −0.50 D spherical equivalent of myopia (cycloplegic autorefraction), were recruited from the faculty and staff of The Ohio State University. Progression is defined as an increase in myopia of at least −0.75 D spherical equivalent as determined by cycloplegic autorefraction. Annual testing includes visual acuity, noncycloplegic autorefraction and autokeratometry, phoria, accommodative lag, response AC/A ratio, cycloplegic autorefraction, videophakometry, ultrasound, and partial coherence interferometry (IOLMaster). Participants’ near activities were assessed using the experience sampling method (ESM). Subjects carried a pager for two 1-week periods and were paged randomly throughout the day. Each time they were paged, they dialed into an automated telephone survey and reported their visual activity at that time. From these responses, the proportion of time spent performing near work was estimated. Results Three-hundred ninety-six subjects were enrolled in SPAN. The mean (± standard deviation) age at baseline was 30.7 ± 3.5 years, 66% were female, 80% were white, 11% were black, and 8% were Asian/Pacific Islander. The mean level of myopia (spherical equivalent) was −3.54 ± 1.77 D, the mean axial length by IOLMaster was 24.6 ± 1.1 mm, and subjects were 1.7 ± 4.0 Δ exophoric. Refractive error was associated with the number of myopic parents (F = 3.83, p = 0.023), and the number of myopic parents was associated with the age of myopia onset (χ2 = 13.78, p = 0.001). In a multivariate analysis, onset of myopia (early

    The Great Salt Lake Basins, Utah, Idaho, and Wyoming is one of 51 study units in the United States where the status and trends of water quality, and the factors controlling water quality, are being studied by the National Water-Quality Assessment Program of the U.S. Geological Survey. The 14,500-square-mile Great Salt Lake Basins study unit encompasses three major river systems that enter Great Salt Lake: the Bear, the Weber, and the Utah Lake/Jordan River systems. The environmental setting of the study unit includes natural and human-related factors that potentially influence the physical, chemical, and/or biological quality of the surface- and ground-water resources. Surface- and ground-water components of the planned assessment activities are designed to evaluate the sources of natural and human-related factors that affect the water quality in the Great Salt Lake Basins study unit.

    Adult antisocial behavior (AAB) is moderately heritable, relatively common and has adverse consequences for individuals and society. We examined the molecular genetic basis of AAB in 1379 participants from a case-control study in which the cases met criteria for alcohol dependence. We also examined whether genes of interest were expressed in human brain. AAB was measured using a count of the number of Antisocial Personality Disorder criteria endorsed under criterion A from the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). Participants were genotyped on the Illumina Human 1M BeadChip. In total, all single-nucleotide polymorphisms (SNPs) accounted for 25% of the variance in AAB, although this estimate was not significant (P=0.09). Enrichment tests indicated that more significantly associated genes were over-represented in seven gene sets, and most were immune related. Our most highly associated SNP (rs4728702, P=5.77 × 10(-7)) was located in the protein-coding adenosine triphosphate-binding cassette, sub-family B (MDR/TAP), member 1 (ABCB1). In a gene-based test, ABCB1 was genome-wide significant (q=0.03). Expression analyses indicated that ABCB1 was robustly expressed in the brain. ABCB1 has been implicated in substance use, and in post hoc tests we found that variation in ABCB1 was associated with DSM-IV alcohol and cocaine dependence criterion counts. These results suggest that ABCB1 may confer risk across externalizing behaviors, and are consistent with previous suggestions that immune pathways are associated with externalizing behaviors. The results should be tempered by the fact that we did not replicate the associations for ABCB1 or the gene sets in a less-affected independent sample. PMID:25918995

    An engineer at AeroVironment's Design Development Center in Simi Valley, California, closely inspects a set of silicon solar cells for potential defects. The cells, fabricated by SunPower, Inc., of Sunnyvale, California, are among 64,000 solar cells which have been installed on the Helios Prototype solar-powered aircraft to provide power to its 14 electric motors and operating systems. Developed by AeroVironment under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, the Helios Prototype is the forerunner of a planned fleet of slow-flying, long duration, high-altitude aircraft which can perform atmospheric science missions and serve as telecommunications relay platforms in the stratosphere. Target goals set by NASA for the giant 246-foot span flying wing include reaching and sustaining subsonic horizontal flight at 100,000 feet altitude in 2001, and sustained continuous flight for at least four days and nights in 2003 with the aid of a regenerative fuel cell-based energy storage system now in development.

    Access to antiretroviral therapy (ART) for HIV infection has expanded rapidly throughout sub-Saharan Africa, but malnutrition and food insecurity have emerged as major barriers to program success. Protein-calorie malnutrition (a common form in the region) hastens HIV disease progression, and food insecurity is a barrier to medication adherence. Analyses of patient outcomes have identified a low body mass index (BMI) at ART initiation as an independent predictor of early mortality, but the causes of low BMI are multi-factorial may represent normal anthropometric variation, chronic inadequate food intake, or wasting associated with HIV and other infections. While there is much experience population-level humanitarian food assistance, few data exist to measure the effectiveness of macronutrient supplementation or to identify individuals most likely to benefit. In this report, we review the current evidence supporting macronutrient supplementation for HIV-infected adults; clinical trials in resource-adequate and resource-constrained settings; and highlight priority areas for future research.

    Background World Health Organization (WHO)/Joint United Nations Programme on AIDS (UNAIDS) has recommended adult male circumcision (AMC) for the prevention of heterosexually acquired HIV infection in men from communities where HIV is hyperendemic and AMC prevalence is low. The objective of this study was to investigate the feasibility of the roll-out of medicalized AMC according to UNAIDS/WHO operational guidelines in a targeted African setting. Methods and Findings The ANRS 12126 “Bophelo Pele” project was implemented in 2008 in the township of Orange Farm (South Africa). It became functional in 5 mo once local and ethical authorizations were obtained. Project activities involved community mobilization and outreach, as well as communication approaches aimed at both men and women incorporating broader HIV prevention strategies and promoting sexual health. Free medicalized AMC was offered to male residents aged 15 y and over at the project's main center, which had been designed for low-income settings. Through the establishment of an innovative surgical organization, up to 150 AMCs under local anesthesia, with sterilized circumcision disposable kits and electrocautery, could be performed per day by three task-sharing teams of one medical circumciser and five nurses. Community support for the project was high. As of November 2009, 14,011 men had been circumcised, averaging 740 per month in the past 12 mo, and 27.5% of project participants agreed to be tested for HIV. The rate of adverse events, none of which resulted in permanent damage or death, was 1.8%. Most of the men surveyed (92%) rated the services provided positively. An estimated 39.1% of adult uncircumcised male residents have undergone surgery and uptake is steadily increasing. Conclusion This study demonstrates that a quality AMC roll-out adapted to African low-income settings is feasible and can be implemented quickly and safely according to international guidelines. The project can be a model for

    Cognitive radio (CR) is an intelligent wireless communication system which can dynamically adjust the parameters to improve system performance depending on the environmental change and quality of service. The core technology for CR is the design of cognitive engine, which introduces reasoning and learning methods in the field of artificial intelligence, to achieve the perception, adaptation and learning capability. Considering the dynamical wireless environment and demands, this paper proposes a design of cognitive engine based on the rough sets (RS) and radial basis function neural network (RBF_NN). The method uses experienced knowledge and environment information processed by RS module to train the RBF_NN, and then the learning model is used to reconfigure communication parameters to allocate resources rationally and improve system performance. After training learning model, the performance is evaluated according to two benchmark functions. The simulation results demonstrate the effectiveness of the model and the proposed cognitive engine can effectively achieve the goal of learning and reconfiguration in cognitive radio.

  15. The Building Bridges Project: Involving Older Adults in the Design of a Communication Technology to Support Peer-to-Peer Social Engagement

    Wherton, Joseph; Prendergast, David

    There are a variety of factors that can lead to social isolation and loneliness in old age, including decline in physical and mental health, as well as change to social environment. The Building Bridges project explores how communication technology can help older adults remain socially connected. This paper will first provide an overview of a prototype communication system designed to support peer-to-peer group interaction. A description of the user-centered design process will be provided to demonstrate the importance of involving older adults at the earliest stages. The implications for designing new technology for older adults are discussed.

  19. A Novel Approach to Decoy Set Generation: Designing a Physical Energy Function Having Local Minima with Native Structure Characteristics

    PubMed Central

    Keasar, Chen; Levitt, Michael

    2009-01-01

    We suggest a new approach to the generation of candidate structures (decoys) for ab initio prediction of protein structures. Our method is based on random sampling of conformation space and subsequent local energy minimization. At the core of this approach lies the design of a novel type of energy function. This energy function has local minima with native structure characteristics and wide basins of attraction. The current work presents our motivation for deriving such an energy function and also tests the derived energy function. Our approach is novel in that it takes advantage of the inherently rough energy landscape of proteins, which is generally considered a major obstacle for protein structure prediction. When local minima have wide basins of attraction, the protein’s conformation space can be greatly reduced by the convergence of large regions of the space into single points, namely the local minima corresponding to these funnels. We have implemented this concept by an iterative process. The potential is first used to generate decoy sets and then we study these sets of decoys to guide further development of the potential. A key feature of our potential is the use of cooperative multi-body interactions that mimic the role of the entropic and solvent contributions to the free energy. The validity and value of our approach is demonstrated by applying it to 14 diverse, small proteins. We show that, for these proteins, the size of conformation space is considerably reduced by the new energy function. In fact, the reduction is so substantial as to allow efficient conformational sampling. As a result we are able to find a significant number of near-native conformations in random searches performed with limited computational resources. PMID:12742025

    Objective There are few published studies describing severe acute respiratory illness (SARI) epidemiology amongst older children and adults from high HIV-prevalence settings. We aimed to describe SARI epidemiology amongst individuals aged ≥5 years in South Africa. Methods We conducted prospective surveillance for individuals with SARI from 2009–2012. Using polymerase chain reaction, respiratory samples were tested for ten viruses, and blood for pneumococcal DNA. Cumulative annual SARI incidence was estimated at one site with population denominators. Findings We enrolled 7193 individuals, 9% (621/7067) tested positive for influenza and 9% (600/6519) for pneumococcus. HIV-prevalence was 74% (4663/6334). Among HIV-infected individuals with available data, 41% of 2629 were receiving antiretroviral therapy (ART). The annual SARI hospitalisation incidence ranged from 325-617/100,000 population. HIV-infected individuals experienced a 13–19 times greater SARI incidence than HIV-uninfected individuals (p<0.001). On multivariable analysis, compared to HIV-uninfected individuals, HIV-infected individuals were more likely to be receiving tuberculosis treatment (odds ratio (OR):1.7; 95%CI:1.1–2.7), have pneumococcal infection (OR 2.4; 95%CI:1.7–3.3) be hospitalised for >7 days rather than <2 days (OR1.7; 95%CI:1.2–2.2) and had a higher case-fatality ratio (8% vs 5%;OR1.7; 95%CI:1.2–2.3), but were less likely to be infected with influenza (OR 0.6; 95%CI:0.5–0.8). On multivariable analysis, independent risk indicators associated with death included HIV infection (OR 1.8;95%CI:1.3–2.4), increasing age-group, receiving mechanical ventilation (OR 6.5; 95%CI:1.3–32.0) and supplemental-oxygen therapy (OR 2.6; 95%CI:2.1–3.2). Conclusion The burden of hospitalized SARI amongst individuals aged ≥5 years is high in South Africa. HIV-infected individuals are the most important risk group for SARI hospitalization and mortality in this setting. PMID:25706880

    Background There is growing interest in the use of technology to enhance the tracking and quality of clinical information available for patients in disaster settings. This paper describes the design and evaluation of the Wireless Internet Information System for Medical Response in Disasters (WIISARD). Materials and methods WIISARD combined advanced networking technology with electronic triage tags that reported victims' position and recorded medical information, with wireless pulse-oximeters that monitored patient vital signs, and a wireless electronic medical record (EMR) for disaster care. The EMR system included WiFi handheld devices with barcode scanners (used by front-line responders) and computer tablets with role-tailored software (used by managers of the triage, treatment, transport and medical communications teams). An additional software system provided situational awareness for the incident commander. The WIISARD system was evaluated in a large-scale simulation exercise designed for training first responders. A randomized trial was overlaid on this exercise with 100 simulated victims, 50 in a control pathway (paper-based), and 50 in completely electronic WIISARD pathway. All patients in the electronic pathway were cared for within the WIISARD system without paper-based workarounds. Results WIISARD reduced the rate of the missing and/or duplicated patient identifiers (0% vs 47%, p<0.001). The total time of the field was nearly identical (38:20 vs 38:23, IQR 26:53–1:05:32 vs 18:55–57:22). Conclusion Overall, the results of WIISARD show that wireless EMR systems for care of the victims of disasters would be complex to develop but potentially feasible to build and deploy, and likely to improve the quality of information available for the delivery of care during disasters.

    2014-12-01

    In this paper, a simple method is presented for tuning weighted PI(λ) + D(μ) controller parameters based on the pole placement controller of pseudo-second-order fractional systems. One of the advantages of this controller is capability of reducing the disturbance effects and improving response to input, simultaneously. In the following sections, the performance of this controller is evaluated experimentally to control the vertical magnetic flux in Damavand tokamak. For this work, at first a fractional order model is identified using output-error technique in time domain. For various practical experiments, having desired time responses for magnetic flux in Damavand tokamak, is vital. To approach this, at first the desired closed loop reference models are obtained based on generalized characteristic ratio assignment method in fractional order systems. After that, for the identified model, a set-point weighting PI(λ) + D(μ) controller is designed and simulated. Finally, this controller is implemented on digital signal processor control system of the plant to fast/slow control of magnetic flux. The practical results show appropriate performance of this controller. PMID:25554294

    Streptococcus pneumoniae is a principal cause of serious illness, including bacteremia, meningitis, and pneumonia, worldwide. Pneumococcal immunization is proven to reduce morbidity and mortality in high-risk adult and elderly populations. Current pneumococcal vaccination practices are suboptimal in part because of recommendation complexity, the high cost of provider-driven immunization interventions, and outreach methods that are not patient-centric. These barriers are amplified within the safety net. This paper identifies efforts by the Los Angeles County Department of Health Services to increase pneumococcal immunization rates for adult indigent patient populations. A 4-part approach will be used to increase vaccination rates: (1) protocol driven care, (2) staff education, (3) electronic identification of eligible patients, and (4) automated patient outreach and scheduling. The proposed analytics plan and potential for scalability are described. (Population Health Management 2016;19:240-247). PMID:26824148

    Background: Due to the high incidence of deaths from breast cancer, high cost of treatment and limited resources, the need to formulate and implement effective programs in reducing the burden of disease is obvious. Care, control and creation of cancer information system having an infrastructure from collection of minimum data sets (MDS) are the top priorities of research in Iran’s Ministry of Health. Methods: This is an applied descriptive research with comparative approach implemented in 2010. MDS for breast cancer on selected countries were searched and reviewed and proposed model based on the country’s need was designed. Research data were implemented in 2 stages; assessment of MDS on selected countries and the validation of the proposed model through several meetings that has been carried out by the Undersecretary for Research and Technology and several oncologists and pathologists. Results: The MDS is composed of 11 parameters in the form of fields in closed structured arrangements with consideration to coding responses. These parameters include: hospital data, demography, referral, physical examination and investigation, diagnostic information, pathology, treatment, palliative care, completion of primary treatment, clinical trials and follow-up. This form is available for use in the cancer registry database. Conclusion: MDS provides an opportunity to strengthen communication between performed researches and research results for the improvement of programs, policies and strategies and provides positive effect on equality in the health system. Although the stages of creating the MDS for breast cancer has been successful, but many challenges has been met until its completion. PMID:23865019

    The extant research is inconclusive regarding the best sampling methods to construct reliable measures of between-person differences in derived parameters of diurnal cortisol, and no study provides such recommendations for detecting within-person changes. These studies determined how many days of sampling are necessary to assess between-person differences and within-person changes over multiple occasions in diurnal mean, diurnal slope, and area under the curve (AUC). Generalizability and decision analyses were conducted on diurnal salivary cortisol data from two separate longitudinal studies, one with younger adults (N = 124) and one with older adults (N = 148). In both studies, results indicated that 3 days of data collection provided the minimal level of reliability in mean cortisol to detect between-person differences; 4–8 days were necessary to reliably assess AUC, and 10 days for cortisol slope. Similarly, in order to reliably characterize within-person changes across occasions, at least 3 days of data collection were needed for mean cortisol and AUC and 5–8 days for slope. Results also indicated that only two samples per day, taken morning and evening, could faithfully reproduce the diurnal slope calculated from 3 or 4 samples (r = .97–.99). Instead of having participants provide many samples per day over the course of a few days, we recommend collecting fewer samples per day over more days. PMID:25137484

  7. V-TIME: a treadmill training program augmented by virtual reality to decrease fall risk in older adults: study design of a randomized controlled trial

    PubMed Central

    2013-01-01

    Background Recent work has demonstrated that fall risk can be attributed to cognitive as well as motor deficits. Indeed, everyday walking in complex environments utilizes executive function, dual tasking, planning and scanning, all while walking forward. Pilot studies suggest that a multi-modal intervention that combines treadmill training to target motor function and a virtual reality obstacle course to address the cognitive components of fall risk may be used to successfully address the motor-cognitive interactions that are fundamental for fall risk reduction. The proposed randomized controlled trial will evaluate the effects of treadmill training augmented with virtual reality on fall risk. Methods/Design Three hundred older adults with a history of falls will be recruited to participate in this study. This will include older adults (n=100), patients with mild cognitive impairment (n=100), and patients with Parkinson’s disease (n=100). These three sub-groups will be recruited in order to evaluate the effects of the intervention in people with a range of motor and cognitive deficits. Subjects will be randomly assigned to the intervention group (treadmill training with virtual reality) or to the active-control group (treadmill training without virtual reality). Each person will participate in a training program set in an outpatient setting 3 times per week for 6 weeks. Assessments will take place before, after, and 1 month and 6 months after the completion of the training. A falls calendar will be kept by each participant for 6 months after completing the training to assess fall incidence (i.e., the number of falls, multiple falls and falls rate). In addition, we will measure gait under usual and dual task conditions, balance, community mobility, health related quality of life, user satisfaction and cognitive function. Discussion This randomized controlled trial will demonstrate the extent to which an intervention that combines treadmill training augmented

    Multicenter clinical registries are increasingly recognized as valuable tools for establishing benchmarks, facilitating patient-centered quality improvement and research. In 2010, the Pediatric and Congenital Electrophysiology Society convened a taskforce of its members to design, construct, and implement a clinical registry known as the Multicenter Pediatric and Adult Congenital EP Quality (MAP-IT) Initiative. The present aim of the MAP-IT Initiative is to create an infrastructure by which we can measurably improve patient-centered outcomes and reduce complications associated with electrophysiology studies and catheter ablation in pediatric and congenital heart disease patients. The purpose of this writing is to report the progress to date from three of the four subcommittees of the MAP-IT taskforce. Specifically, we present our initial set of key data elements and definitions, recommended database table structure, and considerations regarding wide-scale implementation of the registry. Development of a risk/complexity score for use in the MAP-IT registry is presented in a separate companion manuscript. It is our intent that these manuscripts will serve to introduce the electrophysiology and pediatric cardiology community to the MAP-IT initiative and provide a rationale for its design and recommended implementation strategy.

    Further survival improvements of adolescents and young adults (AYA) with cancer are clearly affected by biological characteristics of the malignancies and age-specific needs. Multidisciplinary teams drawing expertice from both pediatric and adult cancer teams as well as clinical trials are required to meet the age specific needs of AYA patients with cancer. In 2011, the first AYA unit was established at the University Hospital Halle (Saale), where patients with newly-diagnosed cancer aged 15-25 are treated interdisciplinary by pediatric and adult oncologists. The enrollment into pediatric or adult clinical trials is controlled by age 18. Over the last 2 years, 19 AYA with cancer have been treated at the unit; and, in turn patients and their relatives reflected a high satisfaction with the offered novel health care approach. In the scope of the future Comprehensive Cancer Center at the University Hospital Halle (Saale), a complete ward is planned for all admitted AYA up to 25 years with cancer. The patients will be treated by a tumor-specialized multidisciplinary team of adult or pediatric oncologists and oncological surgeons. Therefore, we intend to establish a special teaching curriculum for physicians, nurses and psychosocial health care staff. Rather than age, cancer biology of a malignancy, surveillance data of late side effects as well as the age-specific needs of AYA patients will be crucial for best treatment options. PMID:24166088

    The effect of age of acquisition on first- and second-language vowel production was investigated. Eight English vowels were produced by Native Japanese (NJ) adults and children as well as by age-matched Native English (NE) adults and children. Productions were recorded shortly after the NJ participants’ arrival in the USA and then one year later. In agreement with previous investigations [Aoyama, et al., J. Phon. 32, 233–250 (2004)], children were able to learn more, leading to higher accuracy than adults in a year’s time. Based on the spectral quality and duration comparisons, NJ adults had more accurate production at Time 1, but showed no improvement over time. The NJ children’s productions, however, showed significant differences from the NE children’s for English “new” vowels /ɪ/, /ε/, /ɑ/, /ʌ/ and /ʊ/ at Time 1, but produced all eight vowels in a native-like manner at Time 2. An examination of NJ speakers’ productions of Japanese /i/, /a/, /u/ over time revealed significant changes for the NJ Child Group only. Japanese /i/ and /a/ showed changes in production that can be related to second language (L2) learning. The results suggest that L2 vowel production is affected importantly by age of acquisition and that there is a dynamic interaction, whereby the first and second language vowels affect each other.

    Although the positive effects of exercise on the well-being and quality of independent living for older adults are well accepted, many elderly individuals lack access to exercise facilities, or the skills and motivation to perform exercise at home. To provide a more engaging environment that promotes physical activity, various fitness applications have been proposed. Many of the available products, however, are geared toward a younger population and are not appropriate or engaging for an older population. To address these issues, we developed an automated interactive exercise coaching system using the Microsoft Kinect. The coaching system guides users through a series of video exercises, tracks and measures their movements, provides real-time feedback, and records their performance over time. Our system consists of exercises to improve balance, flexibility, strength, and endurance, with the aim of reducing fall risk and improving performance of daily activities. In this paper, we report on the development of the exercise system, discuss the results of our recent field pilot study with six independently living elderly individuals, and highlight the lessons learned relating to the in-home system setup, user tracking, feedback, and exercise performance evaluation.

    2014-01-01

    This study describes the development, field utility, reliability, and validity of the multidimensional Tool for Risk, Interventions, and Outcomes (TRIO) for use in Adult Protective Services (APS). The TRIO is designed to facilitate consistent APS practice and collect data related to multiple dimensions of typical interactions with APS clients, including the investigation and assessment of risks, the provision of APS interventions, and associated health and safety outcomes. Initial tests of the TRIO indicated high field utility, social worker “relevance and buy-in,” and inter-rater reliability. TRIO concurrent validity was demonstrated via appropriate patterns of TRIO item differentiation based on the type of observed confirmed abuse or neglect; and predictive validity was demonstrated by prediction of the risk of actual APS recurrence. The TRIO is a promising new tool that can help meet the challenges of providing and documenting effective APS practices and identifying those at high risk for future APS recurrence. PMID:24848994

    Background Consumer-centered health information systems that address problems related to fragmented health records and disengaged and disempowered patients are needed, as are information systems that support public health monitoring and research. Personally controlled health records (PCHRs) represent one response to these needs. PCHRs are a special class of personal health records (PHRs) distinguished by the extent to which users control record access and contents. Recently launched PCHR platforms include Google Health, Microsoft’s HealthVault, and the Dossia platform, based on Indivo. Objective To understand the acceptability, early impacts, policy, and design requirements of PCHRs in a community-based setting. Methods Observational and narrative data relating to acceptability, adoption, and use of a personally controlled health record were collected and analyzed within a formative evaluation of a PCHR demonstration. Subjects were affiliates of a managed care organization run by an urban university in the northeastern United States. Data were collected using focus groups, semi-structured individual interviews, and content review of email communications. Subjects included: n = 20 administrators, clinicians, and institutional stakeholders who participated in pre-deployment group or individual interviews; n = 52 community members who participated in usability testing and/or pre-deployment piloting; and n = 250 subjects who participated in the full demonstration of which n = 81 initiated email communications to troubleshoot problems or provide feedback. All data were formatted as narrative text and coded thematically by two independent analysts using a shared rubric of a priori defined major codes. Sub-themes were identified by analysts using an iterative inductive process. Themes were reviewed within and across research activities (ie, focus group, usability testing, email content review) and triangulated to identify patterns. Results Low levels of familiarity with

  7. OligoTag: a program for designing sets of tags for next-generation sequencing of multiplexed samples.

    PubMed

    Coissac, Eric

    2012-01-01

    Next-generation sequencing systems allow high-throughput production of DNA sequence data. But this technology is more adapted for analyzing a small number of samples needing a huge amount of sequences rather than a large number of samples needing a small number of sequences. One solution to this problem is sample multiplexing. To achieve this, one can add a small tag at the extremities of the sequenced DNA molecules. These tags will be identified using bioinformatics tools after the sequencing step to sort sequences among samples. The rules to apply for selecting a good set of tags adapted to each situation are described in this chapter. Depending on the number of samples to tag and on the required quality of assignation, different solutions are possible. The software oligoTag, a part of OBITools that computes these sets of tags, is presented with some example sets of tags. PMID:22665273

  8. Effect of running therapy on depression (EFFORT-D). Design of a randomised controlled trial in adult patients [ISRCTN 1894

    2012-01-01

    Background The societal and personal burden of depressive illness is considerable. Despite the developments in treatment strategies, the effectiveness of both medication and psychotherapy is not ideal. Physical activity, including exercise, is a relatively cheap and non-harmful lifestyle intervention which lacks the side-effects of medication and does not require the introspective ability necessary for most psychotherapies. Several cohort studies and randomised controlled trials (RCTs) have been performed to establish the effect of physical activity on prevention and remission of depressive illness. However, recent meta-analysis's of all RCTs in this area showed conflicting results. The objective of the present article is to describe the design of a RCT examining the effect of exercise on depressive patients. Methods/Design The EFFect Of Running Therapy on Depression in adults (EFFORT-D) is a RCT, studying the effectiveness of exercise therapy (running therapy (RT) or Nordic walking (NW)) on depression in adults, in addition to usual care. The study population consists of patients with depressive disorder, Hamilton Rating Scale for Depression (HRSD) ≥ 14, recruited from specialised mental health care. The experimental group receives the exercise intervention besides treatment as usual, the control group receives treatment as usual. The intervention program is a group-based, 1 h session, two times a week for 6 months and of increasing intensity. The control group only performs low intensive non-aerobic exercises. Measurements are performed at inclusion and at 3,6 and 12 months. Primary outcome measure is reduction in depressive symptoms measured by the HRSD. Cardio-respiratory fitness is measured using a sub maximal cycling test, biometric information is gathered and blood samples are collected for metabolic parameters. Also, co-morbidity with pain, anxiety and personality traits is studied, as well as quality of life and cost-effectiveness. Discussion Exercise in

We included randomized and quasi-randomized controlled trials that evaluated an HIV prevention intervention, enrolled participants with histories of criminal justice involvement, and reported biological or behavioral outcomes. We used Cochrane methods to screen 32 271 citations from 16 databases and gray literature. We included 37 trials enrolling n = 12 629 participants. Interventions were 27 psychosocial, 7 opioid substitution therapy, and 3 HIV-testing programs. Eleven programs significantly reduced sexual risk taking, 4 reduced injection drug risks, and 4 increased testing. Numerous interventions may reduce HIV-related risks among adults with criminal justice involvement. Future research should consider process evaluations, programs involving partners or families, and interventions integrating biomedical, psychosocial, and structural approaches. PMID:25211725

    Life stress is a central factor in the onset and course of a wide range of medical and psychiatric conditions. Determining the precise etiological and pathological consequences of stress, though, has been hindered by weaknesses in prevailing definitional and measurement practices. The purpose of the current paper is to evaluate the primary strategies for defining and measuring major and minor acute life events, chronic stressors, and daily hassles as informed by 3 basic scientific premises. The first premise concerns the manner in which stress is conceptualized and operationally defined, and specifically we assert that stress measures must not conflate the stress exposure with the stress response. The second premise concerns how stress exposures are measured, and we provide guidelines for optimizing standardized and sensitive indicators of life stress. The third premise addresses the consequences of variations in the procedures for life event measurement with regard to the validity of the research designs employed. We show that life stress measures are susceptible to several sources of bias, and if these potential sources of bias are not controlled in the design of the research, spurious findings may result. Our goal is to provide a useful guide for researchers who consider life stress to be an important factor in their theoretical models of disease, wish to incorporate measures of life stress in their research, and seek to avoid the common pitfalls of past measurement practices.

    There is a need of standardized methods to assess quality in the youth welfare system. This report is based upon a project ("PädZi") with the objective to develop and implement a tool to evaluate pedagogic effects and to assist in goal attainment processes. A scale was developed to measure the attainment of social competences and individual goals. A set of instruments was administered to control for quality of life and psychiatric symptoms. The whole set of instruments was implemented in 11 institutions and was applied to 920 adolescents. The new instrument meets psychometric quality criteria. Validity was controlled by correlations with CBCL/YABCL and YSR/YASR. After a period of six month significant effects appear in the goal attainment scales as well as the standardized instruments. PädZi is applicable in various institutions of the youth welfare system. PMID:18575056

    Background The United States is currently in an age of obesity and inactivity despite increasing public awareness and scientific knowledge of detrimental long-term health effects of this lifestyle. Behavior-tracking diaries offer an effective strategy for physical activity adherence and weight management. Furthermore, Web-based physical activity diaries can engage meaningful partners in people’s social networks through fun online gaming interactions and generate motivational mechanisms for effective behavioral change and positive health outcomes. Objective Wellness Partners (WP) is a Web-based intervention in the form of a physical activity diary with social networking and game features. Two versions were designed and developed for the purpose of this study—“Diary” only and “Diary+Game”. The objectives of this study included pilot testing the research process of this intervention design, implementation, evaluation, and exploring the effectiveness of social gaming features on adult participants’ physical activity and anthropometric measures. Methods We conducted a field experiment with randomized crossover design. Assessments occurred at baseline, first follow-up (FU, 5-8 weeks after using one version of WP), and second FU (5-8 weeks of using the other version of WP). In the control condition, participants started with the “Diary” version of WP while in the experimental condition, participants started with the “Diary+Game” version of WP. A total of 54 adults (egos) ages 44-88, and their family and friends (alters) ages 17-69 participated in the study in ego-network groups. Both egos and their alters completed online surveys about their exercise habits. In addition, egos completed anthropometric measurements of BMI, fat percentage, and fat mass by bioimpedance. Results From October 2009 to May 2010, flyers, emails, and Web advertisements yielded 335 volunteers who were screened. Rolling recruitment resulted in enrollment of 142 qualified

    Studying aquatic microalgae is essential for monitoring biodiversity and water quality. We designed new sets of 18S rRNA PCR primers for Chlorophyceae and Bacillariophyceae by using the ARB software and implementing a virtual PCR program. The results of specificity analysis showed that most of the targeted algal families were identified and nontargeted organisms, such as fungi or ciliates, were excluded. These newly developed PCR primer sets were also able to amplify microalgal rRNA genes from environmental samples with accurate specificity. These tools could be of great interest for studying freshwater microalgal ecology and for developing bioindicators of the health status of aquatic environments. PMID:19592531

    Purpose To describe the theoretical rationale, intervention design, and clinical trial of a two-year weight control intervention for young adults deployed via social and mobile media. Methods A total of 404 overweight or obese college students from three Southern California universities (Mage = 22(±4) years; MBMI=29(±2.8); 70% female) were randomized to participate in the intervention or to receive an informational web-based weight loss program. The intervention is based on behavioral theory and integrates intervention elements across multiple touch points, including Facebook, SMS, smartphone applications, blogs, and e-mail. Participants are encouraged to seek social support among their friends, self-monitor their weight weekly, post their health behaviors on Facebook, and e-mail their weight loss questions/concerns to a health coach. The intervention is adaptive because new theory-driven and iteratively tailored intervention elements are developed and released over the course of the two-year intervention in response to patterns of use and user feedback. Measures of body mass index, waist circumference, physical activity (PA), sedentary behavior (SED), diet, weight management practices, smoking, alcohol, sleep, body image, self-esteem, and depression occur at 6, 12, 18, and 24 months. Currently, all participants have been recruited, and all are in the final year of the trial. Conclusion Theory-driven, evidence-based strategies for PA, SED, and dietary intake can be embedded in an intervention using social and mobile technologies to promote healthy weight-related behaviors in young adults.

    The purpose of this study was to analyze the influence of the setting and the presence of solid lubricant on the abutment screw surface on the flexural strength of the joint implant/abutment/screw. Forty abutments were connected to external hex implants, divided into 4 groups (n = 10): FE (titanium alloy screw threaded in the extremity), LE (titanium alloy screw with solid lubricant and thread in the extremity), FT (titanium alloy screw with threaded in all its length), and LT (titanium alloy screw with solid lubricant and thread in all its length). Through the mechanical flexural test, the implant/abutment resistance was evaluated with load applied perpendicular to the long axis in a mechanical testing machine (EMIC) under a speed of 0.5 mm/min. Data were submitted to a statistics test, and results showed statistically significant differences between the FE group and the other groups, and the FE group showed the lowest values. The LE group showed greater values than the LT group, and the values were statistically significant. According to the methodology used, it can be concluded that within noncoated titanium screws, a screw threaded along its entire length provided greater rigidity to the implant set, while with the screw containing solid lubricant, the screw threaded in all its length provided less rigidity of the implant set than screws with the thread only on the end. Among screws with the same geometry, those with the solid lubricant are statistically higher than those which do not have threads just at the end, but those with threads along their entire length do not show statistically significant differences.

    Introduction Current guidelines by WHO for cervical cancer screening in low- and middle-income countries involves visual inspection with acetic acid (VIA) of the cervix, followed by treatment during the same visit or a subsequent visit with cryotherapy if a suspicious lesion is found. Implementation of these guidelines is hampered by a lack of: trained health workers, reliable technology, and access to screening facilities. A low cost ultra-portable Point of Care Tampon based digital colposcope (POCkeT Colposcope) for use at the community level setting, which has the unique form factor of a tampon, can be inserted into the vagina to capture images of the cervix, which are on par with that of a state of the art colposcope, at a fraction of the cost. A repository of images to be compiled that can be used to empower front line workers to become more effective through virtual dynamic training. By task shifting to the community setting, this technology could potentially provide significantly greater cervical screening access to where the most vulnerable women live. The POCkeT Colposcope’s concentric LED ring provides comparable white and green field illumination at a fraction of the electrical power required in commercial colposcopes. Evaluation with standard optical imaging targets to assess the POCkeT Colposcope against the state of the art digital colposcope and other VIAM technologies. Results Our POCkeT Colposcope has comparable resolving power, color reproduction accuracy, minimal lens distortion, and illumination when compared to commercially available colposcopes. In vitro and pilot in vivo imaging results are promising with our POCkeT Colposcope capturing comparable quality images to commercial systems. Conclusion The POCkeT Colposcope is capable of capturing images suitable for cervical lesion analysis. Our portable low cost system could potentially increase access to cervical cancer screening in limited resource settings through task shifting to community

    Treatment strategies for patients with depression and cognitive impairment (DEP-CI), who are at high risk to develop a clinical diagnosis of dementia, are not established. This issue is addressed in the donepezil treatment of cognitive impairment and depression (DOTCODE) pilot clinical trial. The DOTCODE study is the first long-term treatment trial that assesses differences in conversion to dementia and cognitive change in DEP-CI patients using a study design of open antidepressant medication plus add-on randomized, double-blind, placebo-controlled treatment with the acetylcholinesterase inhibitor donepezil. In Phase 1, DEP-CI patients receive optimized antidepressant treatment for 16 weeks. In Phase 2, antidepressant treatment is continued with the addition of randomized, double-blind treatment with donepezil or placebo. The total study duration for each patient is 78 weeks (18 months). Eighty DEP-CI outpatients (age 55 to 95 years) are recruited: 40 at New York State Psychiatric Institute/Columbia University and 40 at Duke University Medical Center. The primary outcome is conversion to a clinical diagnosis of dementia. The secondary outcomes are cognitive change scores in Selective Reminding Test (SRT) total recall and the modified Alzheimer’s Disease Assessment Scale (ADAS-cog). Other key assessments include the 24-item Hamilton Depression Rating Scale and antidepressant response; Clinical Global Impression (CGI) for depression, cognition, and global status; neuropsychological test battery for diagnosis; informant report of functional abilities (Pfeffer FAQ); Treatment Emergent Symptom Scale (TESS) for somatic side effects. Apolipoprotein E ε4 status, odor identification deficits, and MRI entorhinal/hippocampal cortex atrophy at baseline are evaluated as neurobiological moderators of donepezil treatment effects.

    Installing material recovery facilities (MRFs) in a solid waste management system could be a feasible alternative to achieve sustainable development goals in urban areas if current household and curbside recycling cannot prove successful in the long run. This paper addresses the optimal site selection and capacity planning for a MRF in conjunction with an optimal shipping strategy of solid waste streams in a multi-district urban region. Screening of material recovery and disposal capacity alternatives can be achieved in terms of economic feasibility, technology limitation, recycling potential, and site availability. The optimization objectives include economic impacts characterized by recycling income and cost components for waste management, while the constraint set consists of mass balance, capacity limitation, recycling limitation, scale economy, conditionality, and relevant screening constraints. A case study for the City of San Antonio, Texas (USA) presents a vivid example where scenario planning demonstrates the robustness and flexibility of this modeling analysis. It proves especially useful when determining MRF ownership structure. Each scenario experiences two case settings: (1) two MRF sites are proposed for selection and (2) a single MRF site is sought. Cost analysis confirms processing fees are not the driving force in the City's operation, but rather shipping cost. Sensitivity analysis solidifies the notion that significant public participation plays the most important role in minimizing solid waste management expenses.

    Environmental stratification consists of dividing the study unit into subareas with homogeneous characteristics to assess natural and anthropogenic factors affecting water quality. The assessment of water quality in streams and in aquifers is based on the sampling design that compares water quality within homogeneous subareas defined by subbasins or aquifer boundaries. The study unit is stratified at four levels for the surface-water component: glacial deposit composition, surficial geology, general land use and land cover, and secondary land use. Ground-water studies emphasize shallow ground water where quality is most likely influenced by overlying land use and land cover. Stratification for ground-water sampling is superimposed on the distribution of shallow aquifers. For each aquifer and surface-water basin this stratification forms the basis for the proposed sampling design used in the Upper Mississippi River Basin National Water-Quality Assessment.

    Specialized, fragmented acute care is not aligned optimally to serve older adults. Person-centered care (PCC) has emerged as an evidence-based solution that involves enlisting patients as partners in treatment planning. Although several efforts have captured person-centered voices in outpatient care, more information is needed at the organizational and provider level to better understand the feasibility, challenges, and effect of PCC in community-based and social services settings. To assess themes and emerging trends, researchers conducted telephone interviews with leaders at nine organizations providing PCC for older adults. Questions were focused on the legacy of PCC services, whether and how PCC was connected to better quality care, and what tools were used for measuring PCC. Three themes on PCC for older adults emerged. (1) Each organization ascribed to a unique definition and operational structure for PCC. (2) Despite these differences, all organizations specified a strong commitment to PCC. Most noted financial resources and staffing as challenges and opportunities affecting feasibility. (3) Terms such as "patient-centered" care and other PCC synonyms may warrant greater clarification, because ideological differences set these classifications apart. Results from this analysis indicate the lack of a single, established definition for PCC. As interest in and support for PCC mounts, organizations in outpatient medical and community-based settings clearly have undertaken individual efforts to interpret what PCC is and how to provide it. Interview responses reflect this inconsistency, highlighting how staff and financing in particular can bolster or burden the PCC paradigm and what a consensus definition could do for the field.

    The amount of energy contained in the solar aureole affects the performance of solar systems. Solar optical systems are, therefore, dependent on the characteristics of the shape of the sun in a specific geographical location. For this reason, the present study proposes the design of solid lenses and mirrors modelled from a set of concentric spherical rings that give a desired distribution of energy in the focal plane. One hundred spherical rings, whose optimum curvature radius values were calculated by Genetic Algorithms, were employed in the modelling process. The study also proposes a design of a petal tool to polish lens and mirror surfaces. (author)

    PubMed Central

    2012-01-01

    Background The German Health Interview and Examination Survey for Adults (DEGS) is part of the recently established national health monitoring conducted by the Robert Koch Institute. DEGS combines a nationally representative periodic health survey and a longitudinal study based on follow-up of survey participants. Funding is provided by the German Ministry of Health and supplemented for specific research topics from other sources. Methods/design The first DEGS wave of data collection (DEGS1) extended from November 2008 to December 2011. Overall, 8152 men and women participated. Of these, 3959 persons already participated in the German National Health Interview and Examination Survey 1998 (GNHIES98) at which time they were 18–79 years of age. Another 4193 persons 18–79 years of age were recruited for DEGS1 in 2008–2011 based on two-stage stratified random sampling from local population registries. Health data and context variables were collected using standardized computer assisted personal interviews, self-administered questionnaires, and standardized measurements and tests. In order to keep survey results representative for the population aged 18–79 years, results will be weighted by survey-specific weighting factors considering sampling and drop-out probabilities as well as deviations between the design-weighted net sample and German population statistics 2010. Discussion DEGS aims to establish a nationally representative data base on health of adults in Germany. This health data platform will be used for continuous health reporting and health care research. The results will help to support health policy planning and evaluation. Repeated cross-sectional surveys will permit analyses of time trends in morbidity, functional capacity levels, disability, and health risks and resources. Follow-up of study participants will provide the opportunity to study trajectories of health and disability. A special focus lies on chronic diseases including asthma

    Decoy database searches are used to filter out false positive protein identifications derived from search engines, but there is no consensus about which decoy is "the best". We evaluate nine different decoy designs using public data sets from samples of known composition. Statistically significant performance differences were found, but no single decoy stood out among the best performers. Ultimately, we recommend peptide level reverse decoys searched independently from the target. PMID:19714810

    Recent trends of population aging and globalization have required an increasing number of individuals to act as long distance caregivers (LDCs) to aging family members. Information technology solutions may ease the burden placed on LDCs by providing remote monitoring, easier access to information and enhanced communication. While some technology tools have been introduced, the information and technology needs of LDCs in particular are not well understood. Consequently, a needs assessment was performed by using video conferencing software to conduct semi-structured interviews with 10 LDCs. Interviews were enriched through the use of stimulus materials that included the demonstration of a prototype LDC health management web/mobile app. Responses were recorded, transcribed and then analyzed. Subjects indicated that information regarding medication regimens and adherence, calendaring, and cognitive health were most needed. Participants also described needs for video calling, activity data regarding sleep and physical exercise, asynchronous communication, photo sharing, journaling, access to online health resources, real-time monitoring, an overall summary of health, and feedback/suggestions to help them improve as caregivers. In addition, all respondents estimated their usage of a LDC health management website would be at least once per week, with half indicating a desire to access the website from a smartphone. These findings are being used to inform the design of a LDC health management website to promote the meaningful involvement of distant family members in the care of older adults. PMID:25954469

    Background Safe Male Circumcision is a proven approach for partial HIV prevention. Several sub Saharan African countries have plans to reach a prevalence of 80% of their adult males circumcised by 2015. These targets require out of ordinary organization, demand creation, timely execution and perhaps the use of SMC devices. Objective To profile Adverse Events rate and acceptance of PrePex, a non surgical device for adult male circumcision. Methods A prospective study, conducted at International Hospital Kampala, Uganda, between August and October 2012. Ethical approval was obtained from Uganda National Council of Science and Technology. Results Of 1,040 men received to undergo SMC, 678 opted for PrePex, 36 were excluded at an initial physical examination screening. 642 were enrolled and consented, and another 17 were excluded before device placement. 625 underwent the procedure. Average age was 24 years (±7). Twelve moderate AEs occurred among 10 participants 12/625, (1.9%). These were all reversible. Five had device displacement, one had an everted foreskin; five had bleeding after the device was removed and one had voiding difficulties. The majority (279 out of 300) of men interviewed complained of some pain within the week of placement. Mean pain score at device placement (using visual analogue scale) was 0.5, at device removal 4.5 and within 2 min of removal the pain score was 1.4. Over 70% of the devices were placed and removed by non-physician clinicians. Presented with a choice, 60% of men chose PrePex over surgical SMC. Close to 90% would recommend the device to their friends. Odour from the necrotic skin was a concern. Removals done 1–2 days earlier than day 7 were beneficial and conferred no extra risk. Conclusion AEs of a moderate or severe nature associated with PrePex were low and reversible. PrePex is feasible for mass safe male circumcision scaling up. PMID:24489754

    In the advent of the installation of a PIT-tag interrogation system in the Cascades Island fish ladder at Bonneville Dam (BON), and other CRB dams, this overview describes in general terms what can and cannot be estimated under seven different scenarios of adult PIT-tag detection capabilities in the CRB. Moreover, this overview attempted to identify minimal adult PIT-tag detection configurations required by the ten threatened Columbia River Basin (CRB) chinook and steelhead ESUs. A minimal adult PIT-tag detection configuration will require the installation of adult PIT-tag detection facilities at Bonneville Dam and another dam above BON. Thus, the Snake River spring/summer and fall chinook salmon, and the Snake River steelhead will require a minimum of three dams with adult PIT-tag detection capabilities to guarantee estimates of ''ocean survival'' and at least of one independent, in-river returning adult survival (e.g., adult PIT-tag detection facilities at BON and LGR dams and at any other intermediary dam such as IHR). The Upper Columbia River spring chinook salmon and steelhead will also require a minimum of three dams with adult PIT-tag detection capabilities: BON and two other dams on the BON-WEL reach. The current CRB dam system configuration and BPA's and COE's commitment to install adult PIT-tag detectors only in major CRB projects will not allow the estimation of an ''ocean survival'' and of any in-river adult survival for the Lower Columbia River chinook salmon and steelhead. The Middle Columbia River steelhead ESU will require a minimum of two dams with adult PIT-tag detection capabilities: BON and another upstream dam on the BON-McN reach. Finally, in spite of their importance in terms of releases, PIT-tag survival studies for the Upper Willamette chinook and Upper Willamette steelhead ESUs cannot be perform with the current CRB dam system configuration and PIT-tag detection capabilities.

    Background Walking is a widely accepted and frequently targeted health promotion approach to increase physical activity (PA). Interventions to increase PA have produced only small improvements. Stronger and more potent behavioral intervention components are needed to increase time spent in PA, improve cardiometabolic risk markers, and optimize health. Objective Our aim is to present the rationale and methods from the WalkIT Trial, a 4-month factorial randomized controlled trial (RCT) in inactive, overweight/obese adults. The main purpose of the study was to evaluate whether intensive adaptive components result in greater improvements to adults’ PA compared to the static intervention components. Methods Participants enrolled in a 2x2 factorial RCT and were assigned to one of four semi-automated, text message–based walking interventions. Experimental components included adaptive versus static steps/day goals, and immediate versus delayed reinforcement. Principles of percentile shaping and behavioral economics were used to operationalize experimental components. A Fitbit Zip measured the main outcome: participants’ daily physical activity (steps and cadence) over the 4-month duration of the study. Secondary outcomes included self-reported PA, psychosocial outcomes, aerobic fitness, and cardiorespiratory risk factors assessed pre/post in a laboratory setting. Participants were recruited through email listservs and websites affiliated with the university campus, community businesses and local government, social groups, and social media advertising. Results This study has completed data collection as of December 2014, but data cleaning and preliminary analyses are still in progress. We expect to complete analysis of the main outcomes in late 2015 to early 2016. Conclusions The Walking Interventions through Texting (WalkIT) Trial will further the understanding of theory-based intervention components to increase the PA of men and women who are healthy, insufficiently

    Application of land surface/hydrologic models within an operational flood forecasting system can provide probable time of occurrence and magnitude of streamflow at specific locations along a stream. Creating time-varying spatial extent of flood inundation and depth requires the use of a hydraulic or hydrodynamic model. Models differ in representing river geometry and surface roughness which can lead to different output depending on the particular model being used. The result from a single hydraulic model provides just one possible realization of the flood extent without capturing the uncertainty associated with the input or the model parameters. The objective of this study is to compare multiple hydraulic models toward generating ensemble flood inundation extents. Specifically, relative performances of four hydraulic models, including AutoRoute, HEC-RAS, HEC-RAS 2D, and LISFLOOD are evaluated under different geophysical conditions in several locations across the United States. By using streamflow output from the same hydrologic model (SWAT in this case), hydraulic simulations are conducted for three configurations: (i) hindcasting mode by using past observed weather data at daily time scale in which models are being calibrated against USGS streamflow observations, (ii) validation mode using near real-time weather data at sub-daily time scale, and (iii) design mode with extreme streamflow data having specific return periods. Model generated inundation maps for observed flood events both from hindcasting and validation modes are compared with remotely sensed images, whereas the design mode outcomes are compared with corresponding FEMA generated flood hazard maps. The comparisons presented here will give insights on probable model-specific nature of biases and their relative advantages/disadvantages as components of an operational flood forecasting system.

    A large-scale design space was constructed using a Bayesian estimation method with a small-scale design of experiments (DoE) and small sets of large-scale manufacturing data without enforcing a large-scale DoE. The small-scale DoE was conducted using various Froude numbers (X(1)) and blending times (X(2)) in the lubricant blending process for theophylline tablets. The response surfaces, design space, and their reliability of the compression rate of the powder mixture (Y(1)), tablet hardness (Y(2)), and dissolution rate (Y(3)) on a small scale were calculated using multivariate spline interpolation, a bootstrap resampling technique, and self-organizing map clustering. The constant Froude number was applied as a scale-up rule. Three experiments under an optimal condition and two experiments under other conditions were performed on a large scale. The response surfaces on the small scale were corrected to those on a large scale by Bayesian estimation using the large-scale results. Large-scale experiments under three additional sets of conditions showed that the corrected design space was more reliable than that on the small scale, even if there was some discrepancy in the pharmaceutical quality between the manufacturing scales. This approach is useful for setting up a design space in pharmaceutical development when a DoE cannot be performed at a commercial large manufacturing scale. PMID:22356256

    To elucidate basic mechanisms underlying neurofeedback we investigated neural mechanisms of training of slow cortical potentials (SCPs) by considering EEG- and fMRI. Additionally, we analyzed the feasibility of a double-blind, placebo-controlled design in NF research based on regulation performance during treatment sessions and self-assessment of the participants. Twenty healthy adults participated in 16 sessions of SCPs training: 9 participants received regular SCP training, 11 participants received sham feedback. At three time points (pre, intermediate, post) fMRI and EEG/ERP-measurements were conducted during a continuous performance test (CPT). Performance-data during the sessions (regulation performance) in the treatment group and the placebo group were analyzed. Analysis of EEG-activity revealed in the SCP group a strong enhancement of the CNV (electrode Cz) at the intermediate assessment, followed by a decrease back to baseline at the post-treatment assessment. In contrast, in the placebo group a continuous but smaller increase of the CNV could be obtained from pre to post assessment. The increase of the CNV in the SCP group at intermediate testing was superior to the enhancement in the placebo group. The changes of the CNV were accompanied by a continuous improvement in the test performance of the CPT from pre to intermediate to post assessment comparable in both groups. The change of the CNV in the SCP group is interpreted as an indicator of neural plasticity and efficiency while an increase of the CNV in the placebo group might reflect learning and improved timing due to the frequent task repetition. In the fMRI analysis evidence was obtained for neuronal plasticity. After regular SCP neurofeedback activation in the posterior parietal cortex decreased from the pre- to the intermediate measurement and increased again in the post measurement, inversely following the U-shaped increase and decrease of the tCNV EEG amplitude in the SCP-trained group

    Background The aim was to study the glycaemic control of type 2 diabetic patients, and to identify factors associated with unacceptable glycaemic control (defined as HbA1c >8.0%). Methods Analysis of data collected in a cross-sectional survey of type 2 diabetic patients in eight SingHealth Polyclinics in January 2009. HbA1c value was measured on the day of the survey, while information on patient and diabetic characteristics was obtained through a questionnaire. Odds ratio of having unacceptable glycaemic control was estimated for selected variables using multiple logistic regression models. Results A total of 688 patients were included in the analysis. The mean (± standard deviation) and median (range) HbA1c levels were 7.6% (± 1.35) and 7.3% (5.0% to 14.0%), respectively. 25.4% of the patients had an unacceptable HbA1c level of >8.0% and the odds of this were higher (p < 0.05) in patients with the following characteristics: younger age, longer diabetes duration, presence of insulin treatment, and poorer compliance to medication. Conclusion Younger adult patients were found to have poorer glycaemic control, and hence targeted educational and behaviour modification programmes would be required to effectively manage this group of patients.

    The design of an electron-beam excited device for millimeter-wave generation is presented. Referred to as a dielectric-loaded power extractor, it is based on the higher-order-mode operation of a dielectric-loaded waveguide. With a matching transition, the unit can deliver power to the output waveguide at one of two frequencies, 20.8 and 35.1 GHz, corresponding to the TM{sub 02} and TM{sub 03} modes, respectively. By properly choosing the thickness of the dielectric lining, both modes are tuned to synchronize with an ultra-relativistic electron beam traversing the unit so that the wakefield generated by the beam is excited at these modes, chosen to be at 20.8 and 35.1 GHz, respectively, both corresponding to a harmonic of the 1.3 GHz operating frequency at an accelerator facility. Power generated in the unintended TM{sub 01} mode is effectively suppressed for bunch train operation by a novel technique. The device consists of a dielectric-loaded decelerating structure and two changeable output couplers to deliver the millimeter-wave power to a standard waveguide. For a drive beam with 50 nC of charge per bunch, power levels of 90.4 and 8.68 MW are expected to be delivered by the device at 20.8 and 35.1 GHz, respectively.

    Introduction Despite decades of experience with community health workers (CHWs) in a wide variety of global health projects, there is no established conceptual framework that structures how implementers and researchers can understand, study and improve their respective programs based on lessons learned by other CHW programs. Objective To apply an original, non-linear framework and case study method, 5-SPICE, to multiple sister projects of a large, international non-governmental organization (NGO), and other CHW projects. Design Engaging a large group of implementers, researchers and the best available literature, the 5-SPICE framework was refined and then applied to a selection of CHW programs. Insights gleaned from the case study method were summarized in a tabular format named the ‘5×5-SPICE chart’. This format graphically lists the ways in which essential CHW program elements interact, both positively and negatively, in the implementation field. Results The 5×5-SPICE charts reveal a variety of insights that come from a more complex understanding of how essential CHW projects interact and influence each other in their unique context. Some have been well described in the literature previously, while others are exclusive to this article. An analysis of how best to compensate CHWs is also offered as an example of the type of insights that this method may yield. Conclusions The 5-SPICE framework is a novel instrument that can be used to guide discussions about CHW projects. Insights from this process can help guide quality improvement efforts, or be used as hypothesis that will form the basis of a program's research agenda. Recent experience with research protocols embedded into successfully implemented projects demonstrates how such hypothesis can be rigorously tested. PMID:23561023

    Numerous studies have indicated a need for a diverse workforce that is more highly educated in STEM and ICT fields, and one that is capable of responding creatively to demands for continual innovation. This paper, in response, chronicles the implementation of the Digital Pathways (DP) program, a two-time ITEST recipient and an ongoing initiative of the Bay Area Video Coalition. DP has provided low-income, underrepresented minority young people with 180 contact hours of activities in digital media production to prepare them to pursue higher education and technology careers. A design-based research approach synthesizes staff interviews with student observations, interviews and artifacts to identify a set of generalizable best practices or design principles for empowering young people to move from being consumers of digital media to producers. These principles are illustrated with a case study of the 3D Animation and Gaming track from the second ITEST grant. Researchers argue for the importance of attending to the noncognitive elements of learning and illustrate ways in which instructors encouraged creative expression, personal agency, and collaboration through long-term projects. They also identify strategies for sustaining young people's participation through the establishment of a supportive community environment.

  3. Determinants of Weight Gain Prevention in Young Adult and Midlife Women: Study Design and Protocol of a Randomized Controlled Trial

    PubMed Central

    2015-01-01

    Background Treatment of overweight and obesity through body weight reduction has been monumentally ineffective as few individuals are able to sustain weight loss. Rather than treating weight gain once it has become problematic, prevention of weight gain over time may be more effective. Objective The aim of this research is to preclude the burden of adult obesity in women by identifying the determinants of weight gain prevention. The objective of this randomized controlled trial (RCT) is to compare a weight gain prevention intervention delivered by the registered dietitian versus counselor. Methods This is a 12-month parallel-arm weight gain prevention RCT designed to increase self-efficacy, self-regulation, outcome expectations and family and social support through the use of a nutrition education intervention in women, aged 18-45 years, from the Urbana-Champaign (Illinois, USA) area. Women have been randomized to registered dietitian, counselor or wait-list control groups (August 2014) and are undergoing weekly nutrition education sessions for four months, followed by monthly sessions for eight months (through August 2015). Outcome measures, including: (1) dietary intake, (2) physical activity, (3) anthropometric and blood pressure measurements, (4) biochemical markers of health, (5) eating behaviors and health perceptions, and (6) mediators of behavior change, were collected before the intervention began (baseline) and will be collected at 3, 6, 9, and 12 months of the study. Results In total, 87 women have been randomized to intervention groups, and 81 women have completed first week of the study. Results are expected in early 2016. Conclusions This RCT is one of the first to examine weight gain prevention in women across normal, overweight, and obese body mass index categories. Results of this research are expected to have application to evidence-based practice in weight gain prevention for women and possibly have implication for policy regarding decreasing the

    Background The obesity epidemic has spread to young adults, leading to significant public health implications later in adulthood. Intervention in early adulthood may be an effective public health strategy for reducing the long-term health impact of the epidemic. Few weight loss trials have been conducted in young adults. It is unclear what weight loss strategies are beneficial in this population. Purpose To describe the design and rationale of the NHLBI-sponsored Cell Phone Intervention for You (CITY) study, which is a single center, randomized three-arm trial that compares the impact on weight loss of 1) a behavioral intervention that is delivered almost entirely via cell phone technology (Cell Phone group); and 2) a behavioral intervention delivered mainly through monthly personal coaching calls enhanced by self-monitoring via cell phone (Personal Coaching group), each compared to; 3) a usual care, advice-only control condition. Methods A total of 365 community-dwelling overweight/obese adults aged 18–35 years were randomized to receive one of these three interventions for 24 months in parallel group design. Study personnel assessing outcomes were blinded to group assignment. The primary outcome is weight change at 12 months. We hypothesize that each active intervention will cause more weight loss than the usual care condition. Study completion is anticipated in 2014. Conclusions If effective, implementation of the CITY interventions could mitigate the alarming rates of obesity in young adults through promotion of weight loss. PMID:24462568

    Background Botswana’s health care system is based on a primary care model. Various national guidelines exist for specific diseases. However, most of the guidelines address management at a tertiary level and often appear nonapplicable for the limited resources in primary care facilities. An integrated symptom-based guideline was developed so as to translate the Botswana national guidelines to those applicable in primary care. The Botswana Primary Care Guideline (BPCG) integrates the care of communicable diseases, including HIV/AIDS and noncommunicable diseases, by frontline primary health care workers. Methods The Department of Family Medicine, Faculty of Medicine, University of Botswana, together with guideline developers from the Knowledge Translation Unit (University of Cape Town) collaborated with the Ministry of Health to develop the guideline. Stakeholder groups were set up to review specific content of the guideline to ensure compliance with Botswana government policy and the essential drug list. Results Participants included clinicians, academics, patient advocacy groups, and policymakers from different disciplines, both private and public. Drug-related issues were identified as necessary for implementing recommendations of the guideline. There was consensus by working groups for updating the essential drug list for primary care and expansion of prescribing rights of trained nurse prescribers in primary care within their scope of practice. An integrated guideline incorporating common symptoms of diseases seen in the Botswana primary care setting was developed. Conclusion The development of the BPCG took a broad consultative approach with buy in from relevant stakeholders. It is anticipated that implementation of the BPCG will translate into better patient outcomes as similar projects elsewhere have done. PMID:27570457

    For semiconductor manufacturers moving toward advanced technology nodes -32nm, 22nm and below - lithography presents a great challenge, because it is fundamentally constrained by basic principles of optical physics. Because no major lithography hardware improvements are expected over the next couple years, Computational Lithography has been recognized by the industry as the key technology needed to drive lithographic performance. This implies not only simultaneous co-optimization of all the lithographic enhancement tricks that have been learned over the years, but that they also be pushed to the limit by powerful computational techniques and systems. In this paper a single computational lithography framework for design, mask, and source co-optimization will be explained in non-mathematical language. A number of memory and logic device results at the 32nm node and below are presented to demonstrate the benefits of Level-Set-Method-based ILT in applications covering design rule optimization, SMO, and full-chip correction.

    Objective: This study examines the International Classification of Functioning, Disability, and Health model (ICF) using a data set of 2,563 community-dwelling elderly with disease-independent measures of mobility, physical activity, and social networking, to represent ICF constructs. Method: The relationship between chronic disease and disability (independent and dependent variables) was examined using logistic regression. To demonstrate variability in activity performance with functional impairment, graphing was used. The relationship between functional impairment, activity performance, and social participation was examined graphically and using ANOVA. The impact of cognitive deficits was quantified through stratifying by dementia. Results: Disability is strongly related to chronic disease (Wald 25.5, p < .001), functional impairment with activity performance (F = 34.2, p < .001), and social participation (F= 43.6, p < .001). With good function, there is considerable variability in activity performance (inter-quartile range [IQR] = 2.00), but diminishes with high impairment (IQR = 0.00) especially with cognitive deficits. Discussion: Environment modification benefits those with moderate functional impairment, but not with higher grades of functional loss. PMID:26472747

    We examined whether self-ratings of "being active" among older people living in four different settings (major city high and lower density suburbs, a regional city, and a rural area) were associated with out-of-home participation and outdoor physical activity. A mixed-methods approach (survey, travel diary, and GPS tracking over a one-week period) was used to gather data from 48 individuals aged over 55 years. Self-ratings of "being active" were found to be positively correlated with the number of days older people spent time away from home but unrelated to time traveled by active means (walking and biking). No significant differences in active travel were found between the four study locations, despite differences in their respective built environments. The findings suggest that additional strategies to the creation of "age-friendly" environments are needed if older people are to increase their levels of outdoor physical activity. "Active aging" promotion campaigns may need to explicitly identify the benefits of walking outdoors to ambulatory older people as a means of maintaining their overall health, functional ability, and participation within society in the long-term and also encourage the development of community-based programs in order to facilitate regular walking for this group.

    We describe a randomized controlled trial, the Lakota Oyate Wicozani Pi Kte (LOWPK) trial, which was designed to determine whether a Web-based diabetes and nutritional intervention can improve risk factors related to cardiovascular disease (CVD) among a group of remote reservation–dwelling adult American Indian men and women with type 2 diabetes who are at high risk for CVD. Enrollment on a rolling basis of 180 planned participants began during 2009; an average 18-month follow-up was completed by June 2011. The primary outcome variable is change in glycosylated hemoglobin level after an average 18-month follow-up period. Secondary outcome variables include changes in low-density lipoprotein cholesterol, systolic blood pressure, body mass index, and smoking status, as well as an evaluation of intervention cost-effectiveness. If effective, the LOWPK trial may serve as a guide for future chronic disease intervention trials in remote, technologically challenged settings. PMID:23001642

    : Friesian-type dairy cows were milked with different machine settings to determine the effect of these settings on teat tissue reaction and on milking characteristics. Three teat-cup liner designs were used with varying upper barrel dimensions (wide-bore WB = 31.6 mm; narrow-bore NB = 21.0 mm; narrow-bore NB1 = 25.0 mm). These liners were tested with alternate and simultaneous pulsation patterns, pulsator ratios (60:40 and 67:33) and three system vacuum levels (40, 44 and 50 kPa). Teat tissue was measured using ultrasonography, before milking and directly after milking. The measurements recorded were teat canal length (TCL), teat diameter (TD), cistern diameter (CD) and teat wall thickness (TWT).Teat tissue changes were similar with a system vacuum level of either 50 kPa (mid-level) or 40 kPa (low-level). Widening the liner upper barrel bore dimension from 21.0 mm (P < 0.01) or 25.0 mm (P < 0.001) to 31.6 mm increased the magnitude of changes in TD and TWT after machine milking. Milk yield per cow was significantly (P < 0.05) higher and cluster-on time was reduced (P < 0.01) with the WB cluster as compared to the NB1 cluster. Minimum changes in teat tissue parameters were achieved with system vacuum level of 40 kPa and 50 kPa using NB and WB clusters, respectively. Similar changes in teat tissue and milk yield per cow were observed with alternate and simultaneous pulsation patterns. Widening pulsator ratio from 60:40 to 67:33 did not have negative effects on changes in teat tissue and had a positive effect on milk yield and milking time. Milk liner design had a bigger effect on teat tissue changes and milking characteristics than pulsation settings. PMID:21851658

    Since the enactment of Environmental Protection Act in 1989 and Department of Biotechnology (DBT) guidelines to deal with genetically modified organisms, India has embarked on establishing various levels of biosafety laboratories to deal with highly infectious and pathogenic organisms. Occurrence of outbreaks due to rapidly spreading respiratory and haemorrhagic fever causing viruses has caused an urgency to create a safe laboratory environment. This has thus become a mandate, not only to protect laboratory workers, but also to protect the environment and community. In India, technology and science are progressing rapidly. Several BSL-3 [=high containment] laboratories are in the planning or execution phase, to tackle biosafety issues involved in handling highly infectious disease agents required for basic research and diagnosis. In most of the developing countries, the awareness about biocontainment has increased but planning, designing, constructing and operating BSL-3 laboratories need regular updates about the design and construction of facilities and clear definition of risk groups and their handling which should be in harmony with the latest international practices. This article describes the major steps involved in the process of construction of a BSL-3 laboratory in Indian settings, from freezing the concept of proposal to operationalization phase. The key to success of this kind of project is strong institutional commitment to biosafety norms, adequate fund availability, careful planning and designing, hiring good construction agency, monitoring by experienced consultancy agency and involvement of scientific and engineering personnel with biocontainment experience in the process.

    Purpose Following the International Classification of Functioning, Disability and Health (ICF) concepts, this study examines body functions such as sensory modulation and sleep quality among adults with learning disabilities (LD). Methods One hundred and ten participants, 55 adults with LD and 55 matched controls (mean age 30 years) filled in a socio-demographic questionnaire, the Adults/Adolescents Sensory Profile (AASP), and the Mini Sleep Questionnaire (MSQ). Chi-tests, Mann-Whitney tests, and Kolmogorov-Smirnov tests were conducted to examine group differences related to socio-demographic characteristics and body functions. Correlation and regression analyses were conducted to examine relationships between body functions. Results Significant differences were found between the groups in: (a) unique socio-demographic variables: high-schools attended, family status and number of children; (b) body functions: low registration and sensory sensitivity (p < .001), sensory avoiding (p = .002), sensory seeking (p = .021) and sleep quality (p < .001). Significant correlations were found between AASP subscale scores and the MSQ final score in each group. Regression analysis revealed that for the entire sample (N = 108), low registration accounted for 10.2% of the variance of sleep quality above group membership (p < .001), while in a separate examination of adults with LD (n = 53), low registration accounted for 19.9% of the variance of sleep quality (p < .001). Conclusions Adults with LD need to be studied through a health-related perspective such as the ICF model to gain further understanding of their unique characteristics and daily needs. Sensory and sleep functions of adults with LD should be further studied in the context of health related quality of life. PMID:25658647

    Background Health behavior change interventions have focused on obtaining short-term intervention effects; few studies have evaluated mid-term and long-term outcomes, and even fewer have evaluated interventions that are designed to maintain and enhance initial intervention effects. Moreover, behavior theory has not been developed for maintenance or applied to maintenance intervention design to the degree that it has for behavior change initiation. Objective The objective of this paper is to describe a study that compared two theory-based interventions (social cognitive theory [SCT] vs goal systems theory [GST]) designed to maintain previously achieved improvements in fruit and vegetable (F&V) consumption. Methods The interventions used tailored, interactive conversations delivered by a fully automated telephony system (Telephone-Linked Care [TLC]) over a 6-month period. TLC maintenance intervention based on SCT used a skills-based approach to build self-efficacy. It assessed confidence in and barriers to eating F&V, provided feedback on how to overcome barriers, plan ahead, and set goals. The TLC maintenance intervention based on GST used a cognitive-based approach. Conversations trained participants in goal management to help them integrate their newly acquired dietary behavior into their hierarchical system of goals. Content included goal facilitation, conflict, shielding, and redundancy, and reflection on personal goals and priorities. To evaluate and compare the two approaches, a sample of adults whose F&V consumption was below public health goal levels were recruited from a large urban area to participate in a fully automated telephony intervention (TLC-EAT) for 3-6 months. Participants who increase their daily intake of F&V by ≥1 serving/day will be eligible for the three-arm randomized controlled trial. A sample of 405 participants will be randomized to one of three arms: (1) an assessment-only control, (2) TLC-SCT, and (3) TLC-GST. The maintenance

    The cold-air performance of an axial-flow power turbine with a variable stator designed for a 112-kW automotive gas-turbine engine was determined at speeds from 30 to 110 percent of design and at pressure ratios from 1.11 to 2.67. Performance is presented in terms of equivalent mass flow, torque, power, and efficiency for stator-vane-chord setting angles of 26 degs, 30 degs, 35 degs (design), 40 degs, 45 degs, and 50 degs. Turbine braking performance at a nominal stator setting angle of 107 degs is also presented. Turbine efficiency increased with increasing stator setting angle. A 10-point efficiency increase was obtained by opening the stator from the design setting angle of 35 degs to a setting angle of 45 degs.

    Consumption of milk fat globule membrane (MFGM) in combination with habitual exercise suppresses age-associated muscle loss. The effects of high dose MFGM, however, are not known. A double-blind, randomized controlled trial with parallel group design was conducted to evaluate the safety of consuming high dose MFGM tablets. The subjects were 32 healthy adult men and women. Subjects were given 5 times the recommended daily intake of the tablets containing 6.5 g of MFGM or whole milk powder for 4 weeks. Stomach discomfort and diarrhea were observed; however, these symptoms were transitory and slight and were not related to consumption of the test tablets. In addition, there were no clinically significant changes in anthropometric measurements or blood tests. Total degree of safety assessed by the physicians of all subjects was "safe." These findings suggest that consumption of the tablets containing 6.5 g MFGM for 4 weeks is safe for healthy adults. PMID:25704503

    Summary Objectives We describe an innovative community-centered participatory design approach, Consumer-centered Participatory Design (C2PD), and the results of applying C2PD to design and develop a web-based fall prevention system. Methods We conducted focus groups and design sessions with English- and Spanish-speaking community-dwelling older adults. Focus group data were summarized and used to inform the context of the design sessions. Descriptive content analysis methods were used to develop categorical descriptions of design session informant’s needs related to information technology. Results The C2PD approach enabled the assessment and identification of informant’s needs of health information technology (HIT) that informed the development of a falls prevention system. We learned that our informants needed a system that provides variation in functions/content; differentiates between actionable/non-actionable information/structures; and contains sensory cues that support wide-ranging and complex tasks in a varied, simple, and clear interface to facilitate self-management. Conclusions The C2PD approach provides community-based organizations, academic researchers, and commercial entities with a systematic theoretically informed approach to develop HIT innovations. Our community-centered participatory design approach focuses on consumer’s technology needs while taking into account core public health functions. PMID:25589909

    Advancing age is associated with reduced levels of physical activity, increased body weight and fat, decreased lean body mass, and a high prevalence of type 2 diabetes (T2D). Resistance training (RT) increases muscle strength and lean body mass, and reduces risk of T2D among older adults. The Resist Diabetes trial will determine if a social cognitive theory (SCT)-based intervention improves RT maintenance in older, prediabetic adults, using a hybrid efficacy/effectiveness approach. Sedentary, overweight/obese (BMI 25-39.9 kg/m2) adults aged 50-69 (N=170) with prediabetes (impaired fasting glucose and/or impaired glucose tolerance) completed a supervised 3-month RT (2x/wk) Initiation Phase and were then randomly assigned (n=159; 94% retention) to one of two 6-month maintenance conditions: SCT or Standard care. The SCT intervention consisted of faded contacts compared to Standard care. Participants continue RT at an approved, self-selected community facility during maintenance. A subsequent 6-month period involves no contact for both conditions. Assessments occur at baseline and months 3 (post-initiation), 9 (post-intervention), and 15 (six months after no contact). Primary outcomes are prediabetes indices (i.e., impaired fasting and 2-hour glucose concentration) and strength. Secondary measures include insulin sensitivity, beta-cell responsiveness, and disposition index (oral glucose and C-peptide minimal model); adherence; body composition; and SCT measures. Resist Diabetes is the first trial to examine the effectiveness of a high fidelity SCT-based intervention for maintaining RT in older adults with prediabetes to improve glucose homeostasis. Successful application of SCT constructs for RT maintenance may support translation of our RT program for diabetes prevention into community settings. PMID:24252311

    The aging population and the growing multimorbidity of the major patient population as well as the advanced (pharmaco)therapeutic treatment options are increasing the complexity of independent drug therapy management and administration. The increased complexity may have an impact on drug adherence (including any need for patients initiated coping strategies), and consequently on the safety and efficacy of the medicine. To overcome adherence issues caused by the design of the medicine, it is crucial that developers consider the age appropriateness of the medicine (route of administration, dosage form, excipients in the composition, frequency of dosing) in meeting patients' needs to manage their therapy without the support of a care giver. In order to understand the scientific evidence on such age appropriately designed medicines for use by older adults, a literature search was performed in the Medline database (all languages included). The search produced 34 publications that met the inclusion and exclusion criteria for the patient population of 65 years an older. An in-depth analysis of the included publications with respect to the methodological quality (study design, data collection, endpoints chosen) and results showed that none of these publications had adequately investigated the age appropriateness of the medicine for use by older adults. The authors consider that the knowledge gap in this area requires attention of all stakeholders in the healthcare community. PMID:25445516

    2012-01-01

    Background In Canada, one in three adults or almost 9 million people report having a chronic condition. Over two thirds of total deaths result from cardiovascular disease, diabetes, cancer and respiratory illness and 77% of persons ≥65 years have at least one chronic condition. Persons with chronic disease are at risk for functional decline; as a result, there is an increased awareness of the significance of functional status as an important health outcome. The purpose of this study was to determine whether patients who receive a multi-component rehabilitation intervention, including online monitoring of function with feedback and self-management workshops, showed less functional decline than case matched controls who did not receive this intervention. In addition, we wanted to determine whether capacity building initiatives within the Family Health Team promote a collaborative approach to Chronic Disease Management. Methods A population-based multi-component rehabilitation intervention delivered to persons with chronic illnesses (≥ 44 yrs) (n = 60) was compared to a group of age and sex matched controls (n = 60) with chronic illnesses receiving usual care within a primary healthcare setting. The population-based intervention consisted of four main components: (1) function-based individual assessment and action planning, (2) rehabilitation self-management workshops, (3) on-line self-assessment of function and (4) organizational capacity building. T-tests and chi-square tests were used for continuous and categorical variables respectively in baseline comparison between groups. Results Two MANOVA showed significant between group differences in patient reported physical functioning (Λ = 0.88, F = (2.86) = 5.97. p = 0.004) and for the physical performance measures collectively as the dependent variable (Λ = 0.80, F = (6.93) = 3.68. p = 0.0025).

    Osteoarthritis (OA) is the most common chronic condition and principal cause of disability among older adults. The current obesity epidemic has contributed to this high prevalence rate. Fortunately both OA symptoms and obesity can be ameliorated through lifestyle modifications. Physical activity (PA) combined with weight management improves physical function among obese persons with knee OA but evidence-based interventions that combine PA and weight management are limited for this population. This paper describes a comparative effectiveness trial testing an evidence-based PA program for adults with lower extremity (LE) OA, Fit and Strong!, against an enhanced version that also addresses weight management based on the evidence-based Obesity Reduction Black Intervention Trial (ORBIT). Adult participants (n=400) with LE OA, age 60+, overweight/obese, and not meeting PA requirements of ≥ 150 min per week, are randomized to one of the two programs. Both 8-week interventions meet 3 times per week and include 60 min of strength, flexibility, and aerobic exercise instruction followed by 30 min of education/group discussion. The Fit and Strong! education sessions focus on using PA to manage OA; whereas Fit and Strong! Plus addresses PA and weight loss management strategies. Maintenance of behavior change is reinforced in both groups during months 3-24 through telephone calls and mailed newsletters. Outcomes are assessed at baseline, and 2, 6, 12, 18, and 24 months. Primary outcomes are dietary change at 2 months followed by weight loss at 6 months that is maintained at 24 months. Secondary outcomes assess PA, physical performance, and anxiety/depression.

    The Neuro-ECAT scanner is a positron emission tomograph designed for high resolution cross-sectional imaging of the adult human head, or the complete torso of a child or small animal. The Neuro-ECAT scanner performs both rectilinear and tomographic scans, in both transmission and emission modes. There are three detector planes, producing five images. Each detector plane contains 88 bismuth germanate detectors, arranged in an octagonal array of 11 detectors per bank. Retained and electrically operated shadow shields provide two choices of reconstructed tomographic resolution, nominally 8.0 and 10.5 mm. Interplane septa, also retained and electrically operated, may be inserted between the detector planes for low noise, highly quantitative measurements, or moved aside for high efficiency scanning of low activity levels. The paper presents the Neuro-ECAT scanner design criteria and a description of the scanner. Data from phantom studies are presented to illustrate system performance.

    In this paper, a simple method is presented for tuning weighted PI{sup λ} + D{sup μ} controller parameters based on the pole placement controller of pseudo-second-order fractional systems. One of the advantages of this controller is capability of reducing the disturbance effects and improving response to input, simultaneously. In the following sections, the performance of this controller is evaluated experimentally to control the vertical magnetic flux in Damavand tokamak. For this work, at first a fractional order model is identified using output-error technique in time domain. For various practical experiments, having desired time responses for magnetic flux in Damavand tokamak, is vital. To approach this, at first the desired closed loop reference models are obtained based on generalized characteristic ratio assignment method in fractional order systems. After that, for the identified model, a set-point weighting PI{sup λ} + D{sup μ} controller is designed and simulated.

    Endoscopy is frequently used in the diagnosis of several gastro-intestinal pathologies as Crohn disease, ulcerative colitis or colorectal cancer. It has great potential as a non-invasive screening technique capable of detecting suspicious alterations in the intestinal mucosa, such as inflammatory processes. However, these early lesions usually cannot be detected with conventional endoscopes, due to lack of cellular detail and the absence of specific markers. Due to this lack of specificity, the development of new endoscopy technologies, which are able to show microscopic changes in the mucosa structure, are necessary. We here present a confocal endomicroscope, which in combination with a wide field fluorescence endoscope offers fast and specific macroscopic information through the use of activatable probes and a detailed analysis at cellular level of the possible altered tissue areas. This multi-modal and multi-scale imaging module, compatible with commercial endoscopes, combines near-infrared fluorescence (NIRF) measurements (enabling specific imaging of markers of disease and prognosis) and confocal endomicroscopy making use of a fiber bundle, providing a cellular level resolution. The system will be used in animal models exhibiting gastro-intestinal diseases in order to analyze the use of potential diagnostic markers in colorectal cancer. In this work, we present in detail the set-up design and the software implementation in order to obtain simultaneous RGB/NIRF measurements and short confocal scanning times.

    Background As the population ages, it is increasingly important to test new models of care that improve life quality and decrease health costs. This paper presents the rationale and design for a randomized clinical trial of a novel interdisciplinary program to reduce disability among low income older adults based on a previous pilot trial of the same design showing strong effect. Methods The CAPABLE (Community Aging in Place, Advancing Better Living for Elders) trial is a randomized controlled trial in which low income older adults with self-care disability are assigned to one of two groups: an interdisciplinary team of a nurse, occupational therapist, and handyman to address both personal and environmental risk factors for disability based on participants’ functional goals, or an attention control of sedentary activities of choice. Both groups receive up to 10 home visits over 4 months. Outcomes The primary outcome is decreased disability in self-care (ADL). Secondary outcomes are sustained decrease in self care disability as well as improvement in instrumental ADLS, strength, balance, walking speed, and health care utilization. Careful cost tracking and analysis using intervention data and claims data will enable direct measurement of the cost impact of the CAPABLE approach. CAPABLE has the potential to leverage current health care spending in Medicaid waivers, Accountable Care Organizations and other capitated systems to save the health care system costs as well as improving low income older adults’ ability to age at home with improved life quality.

    Persons aged over 65 years account for over 75% of healthcare expenditures and deaths attributable to cardiovascular disease (CVD). Accordingly, reducing CVD risk among older adults is an important public health priority. Functional status, determined by measures of physical performance, is an important predictor of cardiovascular outcomes in older adults and declines more rapidly in seniors with hypertension. To date, physical exercise is the primary strategy for attenuating declines in functional status. Yet despite the general benefits of training, exercise alone appears to be insufficient for preventing this decline. Thus, alternative or adjuvant strategies are needed to preserve functional status among seniors with hypertension. Prior data suggest that angiotensin converting enzyme inhibitors (ACEi) may be efficacious in enhancing exercise-derived improvements in functional status yet this hypothesis has not been tested in a randomized controlled trial. The objective of this randomized, double-masked pilot trial is to gather preliminary efficacy and safety data necessary for conducting a full-scale trial to test this hypothesis. Sedentary men and women ≥ 65 years of age with functional limitations and hypertension are being recruited into this 24 week intervention study. Participants are randomly assigned to one of three conditions: (1) ACEi plus exercise training, (2) thiazide diuretic plus exercise training, or (3) AT1 receptor antagonist plus exercise training. The primary outcome is change in walking speed and secondary outcomes consist of other indices of CV risk including exercise capacity, body composition, as well as circulating indices of metabolism, inflammation and oxidative stress.

    High consumption of sugar-sweetened beverages (SSB) contributes to a wide range of poor health outcomes. Further, few US adults drink less than the recommended ≤8 oz per day; and individuals with low socioeconomic, low health literacy status, and in rural areas are even less likely to meet recommendations. Unfortunately, few SSB behavioral interventions exist targeting adults, and none focus on low health literacy in rural areas. Talking Health, a type 1 effectiveness-implementation hybrid trial targeting adults in rural southwest Virginia, was developed using the RE-AIM planning and evaluation framework (reach, effectiveness, adoption, implementation, maintenance). The primary aim of this pragmatic randomized-controlled trial was to determine the effectiveness of a scalable 6-month intervention aimed at decreasing SSB consumption (SIPsmartER) when compared to a matched contact physical activity promotion control group (MoveMore). SIPsmartER was developed based upon the Theory of Planned Behavior and uses health literacy strategies to improve comprehension of the intervention content among participants. MoveMore is based on a research-tested intervention that was adapted to address all theory of planned behavior constructs and health literacy principles. Secondary aims include additional health outcomes (e.g., physical activity, weight) and reach, adoption, implementation, and maintenance indicators. This paper highlights the opportunities and considerations for developing health behavior trials that aim to determine intervention effectiveness, provide all study participants an opportunity to benefit from research participation, and collect key information on reach and the potential for organizational adoption, implementation, and maintenance with the longer-term goal of speeding translation into practice settings.

    As the U.S. population ages, efficacious interventions are needed to manage pain and maintain physical function among older adults with osteoarthritis (OA). Skeletal muscle weakness is a primary contributory factor to pain and functional decline among persons with OA, thus interventions are needed that improve muscle strength. High-load resistance exercise is the best-known method of improving muscle strength; however high-compressive loads commonly induce significant joint pain among persons with OA. Thus interventions with low-compressive loads are needed which improve muscle strength while limiting joint stress. This study is investigating the potential of an innovative training paradigm, known as Kaatsu, for this purpose. Kaatsu involves performing low-load exercise while externally-applied compression partially restricts blood flow to the active skeletal muscle. The objective of this randomized, single-masked pilot trial is to evaluate the efficacy and feasibility of chronic Kaatsu training for improving skeletal muscle strength and physical function among older adults. Participants aged ≥ 60 years with physical limitations and symptomatic knee OA will be randomly assigned to engage in a 3-month intervention of either (1) center-based, moderate-load resistance training, or (2) Kaatsu training matched for overall workload. Study dependent outcomes include the change in 1) knee extensor strength, 2) objective measures of physical function, and 3) subjective measures of physical function and pain. This study will provide novel information regarding the therapeutic potential of Kaatsu training while also informing about the long-term clinical viability of the paradigm by evaluating participant safety, discomfort, and willingness to continually engage in the intervention.

Conclusions Programmes, policies and guidelines that integrate HIV treatment and prevention, sexual and reproductive health and fertility care services in a manner responsive to user values and preferences offer opportunities to maximize demand for and use of these services. For HIV-affected women and couples attempting pregnancy, the provision of comprehensive services using available tools – and the development of new tools that are adaptable to many settings and follow consensus recommendations – is a public health imperative. The impetus now is to design and deliver value-driven inclusive programming to achieve the greatest coverage and impact to reduce HIV transmission during pregnancy attempts. PMID:26643454

    A participatory action approach was used to design and evaluate the acceptability of the Realshare online community. Pre and post-intervention focus groups were conducted and participants were asked to test out Realshare during two intervention periods: when a facilitator was present and when one was not. Focus group data and forum messages were thematically analysed. The themes identified related to participants' website design requirements, how they used the community and the evaluation of Realshare after having used it. Amendments were made to Realshare throughout the project. Realshare is available to young oncology patients in the South West of England. PMID:24470526

    Despite the benefits of regular physical activity among older adults, physical activity rates are low in this population. The Program for Active Aging and Community Engagement (PACE) is an ongoing randomized controlled trial designed to compare the effects of two interventions on physical activity at 12 months among older adults. A total of 300 men and women aged 55 years or older will be randomized into either a healthy aging (HA) control intervention (n = 150), which is largely based upon educational sessions, or a prosocial behavior physical activity (PBPA) intervention (n = 150), which incorporates structured physical activity sessions, cognitive-behavioral counseling, and opportunities to earn food for donation to a regional food bank based on weekly physical activity and volunteering. The PBPA intervention is delivered at a local YMCA, and a regional grocery store chain donates the food to the food bank. Data will be collected at baseline, 3, 6, and 12 months. The primary outcome is physical activity as assessed by the Community Healthy Activities Model Program for Seniors (CHAMPS) Questionnaire at 12 months. Secondary outcomes include physical function and health-related quality of life. If successful, the PACE study will demonstrate that prosocial behavior and volunteerism may be efficaciously incorporated into interventions and will provide evidence for a novel motivating factor for physical activity.

    Many adult patients diagnosed with phenotypically moderate and severe haemophilia living in the Auckland region of New Zealand do not report bleeding episodes within a timeframe that allows for optimal assessment and management. This can result in poor clinical outcomes for patients and poor oversight of the use of expensive clotting factor concentrates. Our goal was to improve both the number and speed at which bleeding episodes were reported to our centre, improving access to care and clinical oversight of the use of expensive factor concentrates and aiding the development of a care partnership with patients. We worked with 70 adult PWH living in the Auckland region of New Zealand with moderate and severe haemophilia A and B. Over a 5-month period between March and July 2013 we used a co-design model to develop and implement a range of strategies to improve the timing and frequency of bleed reporting. Mean bleed reporting time was reduced threefold, with a threefold increase in the number of bleeds reported per month. We reduced the number of bleeding episodes reported outside of a prespecified 48-h time limit by 68%. We significantly improved bleed reporting and time to report, indicating improved access to our services, improved clinical oversight and improved accountability to our national funder. We have achieved a care partnership and a reduction in factor consumption for the study population without compromising the quality of care they receive. PMID:24286288

    Objective The objective of this study was to determine the environmental features that best support aging in place. Method We conducted a realist synthesis, a theory-driven interpretive method of evidence synthesis, of 120+ articles (published 1991–2011) that attempts to explain how place may influence older adults’ decisions about mobility (e.g., physical activity). We developed an initial program theory, reviewed the literature, identified outcomes, analyzed and synthesized patterns, and created a final program theory. Results Safety was a central mechanism, serving as one of the bridges between environmental components (e.g., connectivity, aesthetics, retail and services) and decisions about mobility. Population density, sidewalk presence, and park proximity did not emerge as key factors. Discussion Safety considerations are one of the most prominent influences of older adults’ decisions about mobility. Street connectivity, pedestrian access and transit, and retail and services were also important. These factors are amenable to change and can help promote mobility for older adults. PMID:24788714

    Older adults' difficulties in performing two tasks concurrently have been well documented (Kramer & Madden, 2008). It has been observed that the age-related differences in dual-task performance are larger when the two tasks require similar motor responses (2001) and that in some conditions older adults also show greater susceptibility than younger adults to input interference (Hein & Schubert, 2004). The authors recently observed that even when the two tasks require motor responses, both older and younger adults can learn to perform a visual discrimination task and an auditory discrimination task faster and more accurately (Bherer et al., 2005). In the present study, the authors extended this finding to a dual-task condition that involves two visual tasks requiring two motor responses. Older and younger adults completed a dual-task training program in which continuous individualized adaptive feedback was provided to enhance performance. The results indicate that, even with similar motor responses and two visual stimuli, both older and younger adults showed substantial gains in performance after training and that the improvement generalized to new task combinations involving new stimuli. These results suggest that dual-task skills can be substantially improved in older adults and that cognitive plasticity in attentional control is still possible in old age. PMID:18568979

    The well-documented finding that obese adults have a high likelihood of weight regain following participation in behavioural weight loss programmes highlights the importance of developing more effective approaches for weight loss maintenance. One promising approach is to improve the quality of social support for effective weight control available to an obese individual by including support people in behavioural weight loss programmes. This paper describes the rationale and design of a randomized controlled trial that evaluates the effectiveness of training support people to assist obese adults in their weight management. The study entails a two-arm randomized controlled trial in which obese participants take part in a 1-year (26-session) cognitive behaviour therapy group weight management programme, including motivational interviewing strategies (CBT-MI). In one arm, participants receive CBT-MI alone, while in the second arm (CBT-MI-SP), participants also have a support person who attends 10 group sessions designed to teach effective skills for supporting an individual in healthy weight control. More specifically, support people will be trained in skills that aim to promote self-motivation for weight management. Assessments of anthropometric, medical, behavioural, motivational, psychological and social functioning take place at pre-treatment, post-treatment and a 1-year follow-up. By helping obese participants to increase and sustain their motivation and skills for weight control both during treatment and in the crucial period after treatment cessation through the ongoing input of support people, the CBT-MI-SP approach of the current study has the potential to effectively help patients to achieve sustained weight loss while minimizing the patient's need for ongoing, intensive weight control treatment with its attendant costs.

    Long-term follow-up care of survivors after burn injuries can potentially be improved by the application of patient-reported outcome measures (PROMs). PROMs can inform clinical decision-making and foster communication between the patient and provider. There are no previous reports using real-time, burn-specific PROMs in clinical practice to track and benchmark burn recovery over time. This study examines the feasibility of a computerized, burn-specific PROM, the Young Adult Burn Outcome Questionnaire (YABOQ), with real-time benchmarking feedback in a burn outpatient practice. The YABOQ was redesigned for formatting and presentation purposes using images and transcribed to a computerized format. The redesigned questionnaire was administered to young adult burn survivors (ages 19-30 years, 1-24 months from injury) via an ipad platform in the office before outpatient visits. A report including recovery curves benchmarked to a nonburned relatively healthy age-matched population and to patients with similar injuries was produced for the domains of physical function and social function limited by appearance. A copy of the domain reports as well as a complete copy of the patient's responses to all domain questions was provided for use during the clinical visit. Patients and clinicians completed satisfaction surveys at the conclusion of the visit. Free-text responses, included in the satisfaction surveys, were treated as qualitative data adding contextual information about the assessment of feasibility. Eleven patients and their providers completed the study for 12 clinical visits. All patients found the ipad survey and report "easy" or "very easy" to use. In nine instances, patients "agreed" or "strongly agreed" that it helped them communicate their situation to their doctor/nurse practitioner. Patients "agreed" or "strongly agreed" that the report helped them understand their course of recovery in 10 visits. In 11 visits, the patients "agreed" or "strongly agreed" that

    Although there are efficacious weight loss interventions that can improve health and delay onset of diabetes and hypertension, these interventions have not been translated into clinical practice. The primary objective of this study is to evaluate the effectiveness and cost effectiveness of a tailored lifestyle intervention in primary care patients. Patients were recruited by their primary care physicians and eligible participants were randomized to an enhanced intervention or augmented usual care. All participants met with a lifestyle counselor to set calorie and physical activity goals and to discuss behavioral strategies at baseline, 6 and 12 months. During the first year, enhanced intervention participants receive monthly counseling phone calls to assist in attaining and maintaining their goals. Enhanced intervention participants also receive weekly mailings consisting of tailored and non-tailored print materials and videos focusing on weight loss, physical activity promotion and healthy eating. The second year focuses on maintenance with enhanced intervention participants receiving tailored and non-tailored print materials and videos regularly throughout the year. Augmented usual care participants receive five informational handouts on weight loss across the two years. This enhanced intervention that consists of multiple modalities of print, telephone, and video with limited face-to-face counseling holds promise for being effective for encouraging weight loss, increasing physical activity and healthy eating, and also for being cost effective and generalizable for wide clinical use. This study will fill an important gap in our knowledge regarding the translation and dissemination of research from efficacy studies to best practices in clinical settings. PMID:24937016

This mandate takes effect only if an "affordable" plan is available. The definition of affordability for individuals and families of different incomes or circumstances is a critical decision in implementation and is relevant to any state or federal reform requiring individual premium or cost-sharing contributions, or both. This analysis was done to assist the policy design process in Massachusetts and delineates an empirically based approach to setting affordability standards. PMID:17548341

    Frailty is a multifaceted condition that affects many older adults and marks decline on areas such as cognition, physical condition, and nutritional status. Frail individuals are at increased risk for the development of disability, dementia, and falls. There are hardly any health services that enable the identification of prefrail individuals and that focus on prevention of further functional decline. In this paper, we discuss the development of a community-based, technology-supported health service for detecting prefrailty and preventing frailty and further functional decline via participatory design with a wide range of stakeholders. The result is an innovative service model in which an online platform supports the integration of traditional services with novel, Information Communication Technology supported tools. This service is capable of supporting the different phases of screening and offers training services, by also integrating them with community-based services. The service model can be used as a basis for developing similar services within a wide range of healthcare systems. We present the service model, the general functioning of the technology platform, and the different ways in which screening for and prevention of frailty has been localized. Finally, we reflect on the added value of participatory design for creating such health services. PMID:26346580

    Objective Depression affects one in four adults with type 2 diabetes (T2DM) and is associated with worsened diabetes complications, increased health care costs and early mortality. Rural and low-income urban areas, including the Appalachian region, represent an epicenter of the T2DM epidemic. Program ACTIVE II is a comparative effectiveness treatment trial designed to test whether a combination of cognitive behavioral therapy (CBT) and community-based exercise (EXER) will offer greater improvements in diabetes and depression outcomes compared to individual treatment approaches and usual care (UC). The secondary aims are to assess changes in cardiovascular risk factors across groups and to conduct a cost-effectiveness analysis of predicted incidence of cardiovascular complications across groups. Methods The study is a 2-by-2 factorial randomized controlled trial consisting of 4 treatment groups: CBT alone, EXER alone, combination of CBT and EXER, and UC. Adults with T2DM for > 1 year and who meet DSM-IVTR criteria for Major Depressive Disorder (MDD) are eligible to participate at two rural Appalachian sites (southeastern Ohio and West Virginia) and one urban site (Indianapolis). This type II behavioral translation study uses a community-engaged research (CEnR) approach by incorporating community fitness centers and mental health practices as interventionists. Conclusions This is the first study to evaluate the comparative effectiveness of combined CBT and exercise in the treatment of depression using community-based intervention delivery. This approach may serve as a national model for expanding depression treatment for patients with T2DM.

    Background Mental practice as an additional cognitive therapy is getting increased attention in stroke rehabilitation. A systematic review shows some evidence that several techniques in which movements are rehearsed mentally might be effective but not enough to be certain. This trial investigates whether mental practice can contribute to a quicker and/or better recovery of stroke in two Dutch nursing homes. The objective is to investigate the therapeutic potential of mental practice embedded in daily therapy to improve individually chosen daily activities of adult stroke patients compared to therapy as usual. In addition, we will investigate prognostic variables and feasibility (process evaluation). Methods A randomised, controlled, observer masked prospective trial will be conducted with adult stroke patients in the (sub)acute phase of stroke recovery. Over a six weeks intervention period the control group will receive multi professional therapy as usual. Patients in the experimental group will be instructed how to perform mental practice, and will receive care as usual in which mental practice is embedded in physical, occupation and speech therapy sessions. Outcome will be assessed at six weeks and six months. The primary outcome measure is the patient-perceived effect on performance of daily activities as assessed by an 11-point Likert Scale. Secondary outcomes are: Motricity Index, Nine Hole Peg Test, Barthel Index, Timed up and Go, 10 metres walking test, Rivermead Mobility Index. A sample size of the patients group and all therapists will be interviewed on their opinion of the experimental program to assess feasibility. All patients are asked to keep a log to determine unguided training intensity. Discussion Advantages and disadvantages of several aspects of the chosen design are discussed.

  9. Rationale and study design for a randomised controlled trial to reduce sedentary time in adults at risk of type 2 diabetes mellitus: project stand (Sedentary Time ANd diabetes)

    PubMed Central

    2011-01-01

    Background The rising prevalence of Type 2 Diabetes Mellitus (T2DM) is a major public health problem. There is an urgent need for effective lifestyle interventions to prevent the development of T2DM. Sedentary behaviour (sitting time) has recently been identified as a risk factor for diabetes, often independent of the time spent in moderate-to-vigorous physical activity. Project STAND (Sedentary Time ANd Diabetes) is a study which aims to reduce sedentary behaviour in younger adults at high risk of T2DM. Methods/Design A reduction in sedentary time is targeted using theory driven group structured education. The STAND programme is subject to piloting and process evaluation in line with the MRC framework for complex interventions. Participants are encouraged to self-monitor and self-regulate their behaviour. The intervention is being assessed in a randomised controlled trial with 12 month follow up. Inclusion criteria are a) aged 18-40 years with a BMI in the obese range; b) 18-40 years with a BMI in the overweight range plus an additional risk factor for T2DM. Participants are randomised to the intervention (n = 89) or control (n = 89) arm. The primary outcome is a reduction in sedentary behaviour at 12 months as measured by an accelerometer (count < 100/min). Secondary outcomes include physical activity, sitting/lying time using the ActivPAL posture monitor, fasting and 2 h oral glucose tolerance test, lipids, inflammatory biomarkers, body weight, waist circumference, blood pressure, illness perceptions, and efficacy beliefs for behaviour change. Conclusions This is the first UK trial to address sedentary behaviour change in a population of younger adults at risk of T2DM. The results will provide a platform for the development of a range of future multidisciplinary interventions in this rapidly expanding high-risk population.

    In oncology, vaccine-based immunotherapy often investigates regimens that demonstrate minimal toxicity overall and higher doses may not correlate with greater immune response. Rather than determining the maximum tolerated dose, the goal of the study becomes locating the optimal biological dose, which is defined as a safe dose demonstrating the greatest immunogenicity, based on some predefined measure of immune response. Incorporation of adjuvants, new or optimized peptide vaccines, and combining vaccines with immune modulators may enhance immune response, with the aim of improving clinical response. Innovative dose escalation strategies are needed to establish the safety and immunogenicity of new immunologic combinations. We describe the implementation of an adaptive design for identifying the optimal treatment strategy in a multi-site, FDA-approved, phase I/II trial of a novel vaccination approach using long-peptides plus TLR agonists for resected stage IIB-IV melanoma. Operating characteristics of the design are demonstrated under various possible true scenarios via simulation studies. Overall performance indicates that the design is a practical Phase I/II adaptive method for use with combined immunotherapy agents. The simulation results demonstrate the method's ability to effectively recommend optimal regimens in a high percentage of trials with manageable sample sizes. The numerical results presented in this work include the type of simulation information that aid review boards in understanding design performance, such as average sample size and frequency of early trial termination, which we hope will augment early-phase trial design in cancer immunotherapy.

    The SET protein is a promising drug target in cancer therapy, because of its ability to inhibit the function of the tumor suppressor gene protein phosphatase 2A (PP2A). COG peptides, derived from apolipoprotein E (apoE), are potent antagonists of SET; they induce cytotoxicity in cancer cells upon binding to intracellular SET and modulate the nuclear factor kappa B (NF-κB) signaling pathway. However, the therapeutic potential of COG peptides is limited, because of their poor proteolytic stability and low bioavailability. In this study, the COG peptide, COG1410, was stabilized by grafting it onto the ultrastable cyclic peptide scaffold, Momordica cochinchinensis trypsin inhibitor-II (MCoTI-II). The grafted MCoTI-II peptides were cytotoxic to a cancer cell line and showed high stability in human serum. The most potent grafted MCoTI-II peptide inhibited lipopolysaccharide (LPS)-mediated activation of NF-κB in murine macrophages. Overall, this study demonstrates the application of the MCoTI-II scaffold for the development of stable peptide drugs for cancer therapy. PMID:26685975

    Although influenza vaccination is recommended for all adults annually, the incidence of vaccine failure, defined as weak or absent increase in neutralizing Ab titers, is increased in the elderly compared with young adults. The T follicular helper cell (Tfh) subset of CD4 T cells provides B cell help in germinal centers and is necessary for class-switched Ab responses. Previous studies suggested a role for circulating Tfh cells (cTfh) following influenza vaccination in adults, but cTfh have not been studied in elderly adults in whom weak vaccine responses are often observed. In this study, we studied cTfh expressing CXCR5 and programmed death-1 (PD-1). cTfh from elderly adults were present at reduced frequency, had decreased in vitro B cell help ability, and had greater expression of ICOS compared with young adults. At 7 d after inactivated influenza vaccination, cTfh correlated with influenza vaccine-specific IgM and IgG responses in young adults but not in elderly adults. In sum, we have identified aging-related changes in cTfh that correlated with reduced influenza vaccine responses. Future rational vaccine design efforts should incorporate Tfh measurement as an immune correlate of protection, particularly in the setting of aging. PMID:25172499

    In a study of talker intelligibility, 45 voices (adults, 11-12 year old children) were presented to 135 listeners (adults, 11-12, and 7-8 year olds). Word materials were presented in a ``single-word'' condition, and in a ``triplet'' condition, where a ``normalizing'' precursor sentence preceded three keywords. In both conditions, voices were randomized, with no consecutive presentations from the same speaker. The specially designed word-set consisted of 124 words chosen to maximize consonant confusions. Adult female speakers were significantly more intelligible than other groups, as predicted by previous research, but the difference was small. The error rates for 7-8 year olds were slightly but significantly higher than those for the older children and adults. The effect of presentation condition, however, was not significant for any listener group. Across all listener groups, rankings of speakers by error rates were strikingly consistent, with a distinct cluster of eight low-intelligibility speakers common to all listener groups. This suggests that speaker intelligibility is little influenced by listener-related factors. In terms of their perception of speaker characteristics, children aged seven and above are showing similar patterns of behavior to adults, even though the younger children showed marginally higher error rates.

    Background The primary aim of this study was to compare the efficacy of three physical activity (PA) behavioural intervention strategies in a sample of adults with type 2 diabetes. Method/Design Participants (N = 287) were randomly assigned to one of three groups consisting of the following intervention strategies: (1) standard printed PA educational materials provided by the Canadian Diabetes Association [i.e., Group 1/control group)]; (2) standard printed PA educational materials as in Group 1, pedometers, a log book and printed PA information matched to individuals' PA stage of readiness provided every 3 months (i.e., Group 2); and (3) PA telephone counseling protocol matched to PA stage of readiness and tailored to personal characteristics, in addition to the materials provided in Groups 1 and 2 (i.e., Group 3). PA behaviour measured by the Godin Leisure Time Exercise Questionnaire and related social-cognitive measures were assessed at baseline, 3, 6, 9, 12 and 18-months (i.e., 6-month follow-up). Clinical (biomarkers) and health-related quality of life assessments were conducted at baseline, 12-months, and 18-months. Linear Mixed Model (LMM) analyses will be used to examine time-dependent changes from baseline across study time points for Groups 2 and 3 relative to Group 1. Discussion ADAPT will determine whether tailored but low-cost interventions can lead to sustainable increases in PA behaviours. The results may have implications for practitioners in designing and implementing theory-based physical activity promotion programs for this population.

    A receptor-independent (RI) four-dimensional structure-activity relationship (4D-QSAR) formalism was applied to a set of sixty-four β-N-biaryl ether sulfonamide hydroxamate derivatives, previously reported as potent inhibitors against matrix metalloproteinase subtype 9 (MMP-9). MMP-9 belongs to a group of enzymes related to the cleavage of several extracellular matrix components and has been associated to cancer invasiveness/metastasis. The best RI 4D-QSAR model was statistically significant (N=47; r(2) =0.91; q(2) =0.83; LSE=0.09; LOF=0.35; outliers=0). Leave-N-out (LNO) and y-randomization approaches indicated the QSAR model was robust and presented no chance correlation, respectively. Furthermore, it also had good external predictability (82 %) regarding the test set (N=17). In addition, the grid cell occupancy descriptors (GCOD) of the predicted bioactive conformation for the most potent inhibitor were successfully interpreted when docked into the MMP-9 active site. The 3D-pharmacophore findings were used to predict novel ligands and exploit the MMP-9 calculated binding affinity through molecular docking procedure. PMID:27492238

    Background Limited and fragmented data collection systems exist for burn injury. A global registry may lead to better injury estimates and identify risk factors. A collaborative effort involving the WHO, the Global Alliance for Clean Cookstoves, the CDC and the International Society for Burn Injuries was undertaken to simplify and standardise inpatient burn data collection. An expert panel of epidemiologists and burn care practitioners advised on the development of a new Global Burn Registry (GBR) form and online data entry system that can be expected to be used in resource-abundant or resource-limited settings. Methods International burn organisations, the CDC and the WHO solicited burn centre participation to pilot test the GBR system. The WHO and the CDC led a webinar tutorial for system implementation. Results During an 8-month period, 52 hospitals in 30 countries enrolled in the pilot and were provided the GBR instrument, guidance and a data visualisation tool. Evaluations were received from 29 hospitals (56%). Key findings Median time to upload completed forms was <10 min; physicians most commonly entered data (64%), followed by nurses (25%); layout, clarity, accuracy and relevance were all rated high; and a vast majority (85%) considered the GBR ‘highly valuable’ for prioritising, developing and monitoring burn prevention programmes. Conclusions The GBR was shown to be simple, flexible and acceptable to users. Enhanced regional and global understanding of burn epidemiology may help prioritise the selection, development and testing of primary prevention interventions for burns in resource-limited settings.

    The Declaration of Helsinki and the Council of the International Organization of Medical Sciences provide guidance on standards of care and prevention in clinical trials. In the current and increasingly challenging research environment, the ethical status of a trial design depends not only on protection of participants, but also on social value, feasibility, and scientific validity. Using the example of a study assessing efficacy of a vaccine to prevent human papilloma virus in HIV-1 infected adolescent girls in low resource countries without access to the vaccine, we compare several trial designs which rank lower on some criteria and higher on others, giving rise to difficult trade-offs. This case demonstrates the need for developing more nuanced guidance documents to help researchers balance these often conflicting criteria. PMID:23725055

    2013-01-01

    Background Weight gain during young adulthood is common and is associated with increased cardiovascular risk. Preventing this weight gain from occurring may be critical to improving long-term health. Few studies have focused on weight gain prevention, and these studies have had limited success. SNAP (Study of Novel Approaches to Weight Gain Prevention) is an NIH-funded randomized clinical trial examining the efficacy of two novel self-regulation approaches to weight gain prevention in young adults compared to a minimal treatment control. The interventions focus on either small, consistent changes in eating and exercise behaviors, or larger, periodic changes to buffer against expected weight gains. Methods/Design SNAP targets recruitment of six hundred young adults (18–35 years) with a body mass index between 21.0-30.0 kg/m2, who will be randomly assigned with equal probability to: (1) minimal intervention control; (2) self-regulation with Small Changes; or (3) self-regulation with Large Changes. Both interventions receive 8 weekly face-to-face group sessions, followed by 2 monthly sessions, with two 4-week refresher courses in each of subsequent years. Participants are instructed to report weight via web at least monthly thereafter, and receive monthly email feedback. Participants in Small Changes are taught to make small daily changes (~100 calorie changes) in how much or what they eat and to accumulate 2000 additional steps per day. Participants in Large Changes are taught to create a weight loss buffer of 5–10 pounds once per year to protect against anticipated weight gains. Both groups are encouraged to self-weigh daily and taught a self-regulation color zone system that specifies action depending on weight gain prevention success. Individualized treatment contact is offered to participants who report weight gains. Participants are assessed at baseline, 4 months, and then annually. The primary outcome is weight gain over an average of 3 years of follow

    2012-01-01

    Background Childhood obesity in rural communities is a serious but understudied problem. The current experiment aims to assess a wide range of obesity risk factors among rural youth and to offer an 8-month intervention program for parents to reduce obesity risk in their preteen child. Methods/Design A two-group, repeated measures design is used to assess the effectiveness of the 4-Health intervention program. Assessments include anthropometric measures, child self-evaluations, parent self-evaluations, and parent evaluations of child. County Extension agents from 21 rural Montana counties recruit approximately 150 parent–child dyads and counties are semi-randomly assigned to the active intervention group (4-Health Educational Program) or a “best-practices” (Healthy Living Information) control group. Discussion This study will shed light on the effectiveness of this parent-only intervention strategy in reducing obesity risk factors among rural preteens. The 4-Health program is designed to provide information and skills development for busy rural parents that will increase healthy lifestyles of their preteen children and improve the parents’ ability to intervene effectively in the lives of their families during this critical developmental period.

Few randomized controlled trials (RCTs) have focused on strategies to improve outpatient adherence or to reduce reproductive morbidity in this population. This paper describes the research methods and preliminary effectiveness of recruitment, retention, and intervention strategies employed in a novel RCT designed to test a technology-enhanced community-health nursing (TECH-N) intervention among urban AYA with PID. Methods AYA women aged 13–25 years were recruited during acute PID visits in outpatient clinics and emergency departments (ED) to participate in this IRB-approved trial. Participants completed an audio-computerized self-interview (ACASI), provided vaginal specimens, and were randomized to standard treatment or the intervention. Intervention participants received text-messaging support for 30 days and a community health nurse (CHN) interventionist performed a home visit with clinical assessment within 5 days after enrollment. All patients received a full course of medications and completed research visits at 14-days (adherence), 30 days and 90 days with by an outreach worker. STI testing performed at the 30-and 90-day visits. Exploratory analyses using descriptive statistics were conducted to examine recruitment, retention, and follow-up data to test the overall design of the intervention. Results In the first 48 months, 64% of 463 patients were eligible for the study and 81.2% of 293 eligible patients were recruited for the study (63.3%); 238 (81.2%) of eligible patients were enrolled. Most participants were African American (95.6%) with a mean age of 18.6 (2.3). Ninety-four percent of individuals assigned to the TECH-N intervention completed the nursing visits. All completed visits have been within the 5-day window and over 90% of patients in both arms have been retained over the 3

    Chrysler Corp. and LLNL have entered into a collaboration to enhance the NDE technology at the Kokomo transmission plant. The project spans 3 years and a wide variety of different projects. Goals are making NDE automated, reliable, and capable of avoiding destructive testing. This requires NDE systems to be better utilized by quality teams on the shop floor and better connected for providing in one place a sufficient set of data for identifying problems in a manufacturing operation, and prescribing an adjustment. The approach is illustrated on two different processes, laser welding and pressure die casting; in each case data are combined from different NDE systems to enable a decision on an adjustment in process variables.

    Recording setting changes within an accelerator facility provides information that can be used to answer questions about when, why, and how changes were made to some accelerator system. This can be very useful during normal operations, but can also aid with security concerns and in detecting unusual software behavior. The Set History System (SHS) is a new client-server system developed at the Collider-Accelerator Department of Brookhaven National Laboratory to provide these capabilities. The SHS has been operational for over two years and currently stores about IOOK settings per day into a commercial database management system. The SHS system consists of a server written in Java, client tools written in both Java and C++, and a web interface for querying the database of setting changes. The design of the SHS focuses on performance, portability, and a minimal impact on database resources. In this paper, we present an overview of the system design along with benchmark results showing the performance and reliability of the SHS over the last year.

    Hyperboloid gear drives with face mating gears are used to transform rotations between shafts with non-parallel and non-intersecting axes. A special case of these transmissions are Spiroid1 and Helicon gear drives. The classical gear drives of this type are Archimedean ones. The objective of this study are hyperboloid gear drives with face meshing, when the pinion has threads of conic convolute, Archimedean and involute types, or the pinion has threads of cylindrical convolute, Archimedean and involute types. For simplicity, all three type transmissions with face mating gears and a conic pinion are titled Spiroid and all three type trans- missions with face mating gears and a cylindrical pinion are titled Helicon. Principles of the mathematical modelling of tooth contact synthesis are discussed in Part 1: Basic theoretical and CAD experience of this study. The second part of this article is a brief overview of the innovations and inventions created in this field at the Institute of Mechanics - Bulgarian Academy of Sciences in the last three decades. This study is also dedicated on elaboration of the specialized face gear sets for implementation into bio-robot hand. It is based on the application of 3D software technology, using 3D print for the realization of the physical models of the gear drives.

    Scaffolds made of aligned nanofibers are favorable for nerve regeneration due to their superior nerve cell attachment and proliferation. However, it is challenging not only to produce a neat mat or a conduit form with aligned nanofibers but also to use these for surgical applications as a nerve guide conduit due to their insufficient mechanical strength. Furthermore, no studies have been reported on the fabrication of aligned nanofibers and randomly-oriented nanofibers on the same mat. In this study, we have successfully produced a mat with both aligned and randomly-oriented nanofibers by using a novel electrospinning set up. A new conduit with a highly-aligned electrospun mat is produced with this modified electrospinning method, and this proposed conduit with favorable features, such as selective permeability, hydrophilicity and nerve growth directional steering, were fabricated as nerve guide conduits (NGCs). The inner surface of the nerve conduit is covered with highly aligned electrospun nanofibers and is able to enhance the proliferation of neural cells. The central part of the tube is double-coated with randomly-oriented nanofibers over the aligned nanofibers, strengthening the weak mechanical strength of the aligned nanofibers. PMID:27021221

    A 51-cm-diam. model of a short-haul fan stage was tested. Surveys of the air flow conditions ahead of the rotor, between the rotor and stator, and behind the stator were made over the stable operating range of the stage. At the design speed of 213.3 m/sec and weight flow of 26.7 kg/sec, the stage pressure ratio and efficiency are 1.18 and 0.87, respectively. The rotor peak efficiency of 0.92 occurred at flow rate of 30.5 kg/sec. Peak stage efficiency of 0.09 was obtained at 110 percent speed at a pressure ratio of 1.218 and a weight flow of 30.2 kg/sec. Maximum stage pressure ratio is 1.269 at 120 percent speed.

    2002-03-22

    Version 00 SETS is used for symbolic manipulation of Boolean equations, particularly the reduction of equations by the application of Boolean identities. It is a flexible and efficient tool for performing probabilistic risk analysis (PRA), vital area analysis, and common cause analysis. The equation manipulation capabilities of SETS can also be used to analyze noncoherent fault trees and determine prime implicants of Boolean functions, to verify circuit design implementation, to determine minimum cost fire protectionmore » requirements for nuclear reactor plants, to obtain solutions to combinatorial optimization problems with Boolean constraints, and to determine the susceptibility of a facility to unauthorized access through nullification of sensors in its protection system. Two auxiliary programs, SEP and FTD, are included. SEP performs the quantitative analysis of reduced Boolean equations (minimal cut sets) produced by SETS. The user can manipulate and evaluate the equations to find the probability of occurrence of any desired event and to produce an importance ranking of the terms and events in an equation. FTD is a fault tree drawing program which uses the proprietary ISSCO DISSPLA graphics software to produce an annotated drawing of a fault tree processed by SETS. The DISSPLA routines are not included.« less

    Background Stent thrombosis is a lethal complication of endovascular intervention. Concern has been raised for the inherent risk associated with specific stent designs and drug-eluting coatings, yet clinical and animal support are equivocal. Methods and Results We examined whether drug-eluting coatings are inherently thrombogenic and if the response to these materials was determined to a greater degree by stent design and deployment using custom-built stents. Drug/polymer coatings uniformly reduce rather than increase thrombogenicity relative to matched bare-metal counterparts (0.65-fold, p=0.011). Thick-strutted (162 μm) stents were 1.5-fold more thrombogenic than otherwise identical thin-strutted (81 μm) devices in ex vivo flow loops (p<0.001), commensurate with 1.6-fold greater thrombus coverage three days after implantation in porcine coronary arteries (p=0.004). When bare-metal stents were deployed in malapposed or overlapping configurations, thrombogenicity increased compared to apposed, length-matched controls (1.58-fold, p=0.001 and 2.32-fold, p<0.001). The thrombogenicity of polymer-coated stents with thin struts was lowest in all configurations and remained insensitive to incomplete deployment. Computational modeling-based predictions of stent-induced flow derangements correlated with spatial distribution of formed clots. Conclusions Contrary to popular conception drug/polymer coatings do not inherently increase acute stent clotting – they reduce thrombosis. However, strut dimensions and positioning relative to the vessel wall are critical factors in modulating stent thrombogenicity. Optimal stent geometries and surfaces, as demonstrated with thin stent struts, help reduce the potential for thrombosis despite complex stent configurations and variability in deployment.

  7. Quality of life of residents with dementia in long-term care settings in the Netherlands and Belgium: design of a longitudinal comparative study in traditional nursing homes and small-scale living facilities

    PubMed Central

    2011-01-01

    Background The increase in the number of people with dementia will lead to greater demand for residential care. Currently, large nursing homes are trying to transform their traditional care for residents with dementia to a more home-like approach, by developing small-scale living facilities. It is often assumed that small-scale living will improve the quality of life of residents with dementia. However, little scientific evidence is currently available to test this. The following research question is addressed in this study: Which (combination of) changes in elements affects (different dimensions of) the quality of life of elderly residents with dementia in long-term care settings over the course of one year? Methods/design A longitudinal comparative study in traditional and small-scale long-term care settings, which follows a quasi-experimental design, will be carried out in Belgium and the Netherlands. To answer the research question, a model has been developed which incorporates relevant elements influencing quality of life in long-term care settings. Validated instruments will be used to evaluate the role of these elements, divided into environmental characteristics (country, type of ward, group size and nursing staff); basic personal characteristics (age, sex, cognitive decline, weight and activities of daily living); behavioural characteristics (behavioural problems and depression); behavioural interventions (use of restraints and use of psychotropic medication); and social interaction (social engagement and visiting frequency of relatives). The main outcome measure for residents in the model is quality of life. Data are collected at baseline, after six and twelve months, from residents living in either small-scale or traditional care settings. Discussion The results of this study will provide an insight into the determinants of quality of life for people with dementia living in traditional and small-scale long-term care settings in Belgium and the

  11. Linking morphodynamic response with sediment mass balance on the Colorado River in Marble Canyon: issues of scale, geomorphic setting, and sampling design

    Measurements of morphologic change are often used to infer sediment mass balance. Such measurements may, however, result in gross errors when morphologic changes over short reaches are extrapolated to predict changes in sediment mass balance for long river segments. This issue is investigated by examination of morphologic change and sediment influx and efflux for a 100 km segment of the Colorado River in Grand Canyon, Arizona. For each of four monitoring intervals within a 7 year study period, the direction of sand-storage response within short morphologic monitoring reaches was consistent with the flux-based sand mass balance. Both budgeting methods indicate that sand storage was stable or increased during the 7 year period. Extrapolation of the morphologic measurements outside the monitoring reaches does not, however, provide a reasonable estimate of the magnitude of sand-storage change for the 100 km study area. Extrapolation results in large errors, because there is large local variation in site behavior driven by interactions between the flow and local bed topography. During the same flow regime and reach-average sediment supply, some locations accumulate sand while others evacuate sand. The interaction of local hydraulics with local channel geometry exerts more control on local morphodynamic response than sand supply over an encompassing river segment. Changes in the upstream supply of sand modify bed responses but typically do not completely offset the effect of local hydraulics. Thus, accurate sediment budgets for long river segments inferred from reach-scale morphologic measurements must incorporate the effect of local hydraulics in a sampling design or avoid extrapolation altogether.

    2011-01-01

    With emergence of new technologies, there has been an explosion of basic and clinical research on the affective and cognitive neuroscience of face processing and emotion perception. Adult emotional face stimuli are commonly used in these studies. For developmental research, there is a need for a validated set of child emotional faces. This paper describes the development of the NIMH Child Emotional Faces Picture Set (NIMH-ChEFS), a relatively large stimulus set with high quality, color images of the emotional faces of children. The set includes 482 photos of fearful, angry, happy, sad and neutral child faces with two gaze conditions: direct and averted gaze. In this paper we describe the development of the NIMH-ChEFS and data on the set’s validity based on ratings by 20 healthy adult raters. Agreement between the a priori emotion designation and the raters’ labels was high and comparable with values reported for commonly used adult picture sets. Intensity, representativeness, and composite “goodness” ratings are also presented to guide researchers in their choice of specific stimuli for their studies. These data should give researchers confidence in the NIMH-ChEFS’s validity for use in affective and social neuroscience research. PMID:22547297

    2015-01-01

    Background: Adverse drug event (ADE) detection is an important priority for patient safety research. Trigger tools have been developed to help identify ADEs. In previous work we developed seven concurrent, action-oriented, electronic trigger algorithms designed to prompt clinicians to address ADEs in outpatient care. Objectives: We assessed the potential adoption and usefulness of the seven triggers by testing the positive predictive validity and obtaining stakeholder input. Methods: We adapted ADE triggers, “bone marrow toxin—white blood cell count (BMT-WBC),” “bone marrow toxin - platelet (BMT-platelet),” “potassium raisers,” “potassium reducers,” “creatinine,” “warfarin,” and “sedative hypnotics,” with logic to suppress flagging events with evidence of clinical intervention and applied the triggers to 50,145 patients from three large health care systems. Four pharmacists assessed trigger positive predictive value (PPV) with respect to ADE detection (conservatively excluding ADEs occurring during clinically appropriate care) and clinical usefulness (i.e., whether the trigger alert could change care to prevent harm). We measured agreement between raters using the free kappa and assessed positive PPV for the trigger’s detection of harm, clinical usefulness, and both. Stakeholders from the participating health care systems rated the likelihood of trigger adoption and the perceived ease of implementation. Findings: Agreement between pharmacist raters was moderately high for each ADE trigger (kappa free > 0.60). Trigger PPVs for harm ranged from 0 (Creatinine, BMT-WBC) to 17 percent (potassium raisers), while PPV for care change ranged from 0 (WBC) to 60 percent (Creatinine). Fifteen stakeholders rated the triggers. Our assessment identified five of the seven triggers as good candidates for implementation: Creatinine, BMT-Platelet, Potassium Raisers, Potassium Reducers, and Warfarin. Conclusions: At least five outpatient ADE triggers

    Background Recurrent hospital admissions are common among patients admitted for acute decompensated heart failure (ADHF), but identification of patients at risk for rehospitalization remains challenging. Contemporary heart failure (HF) management programs have shown modest ability to reduce readmissions, partly because they monitor signs or symptoms of HF worsening that appear late during decompensation. Detecting early stages of HF decompensation might allow for immediate application of effective HF therapies, thereby potentially reducing HF readmissions. One of the earliest indicators of HF decompensation is intrathoracic fluid accumulation, which can be assessed using transthoracic bioimpedance. Objective The SENTINEL-HF study is a prospective observational study designed to test a novel, wearable HF monitoring system as a predictor of HF decompensation among patients discharged after hospitalization for ADHF. Methods SENTINEL-HF tests the hypothesis that a decline in transthoracic bioimpedance, as assessed daily with the Philips fluid accumulation vest (FAV) and transmitted using a mobile phone, is associated with HF worsening and rehospitalization. According to pre-specified power calculations, 180 patients admitted with ADHF are enrolled. Participants transmit daily self-assessments using the FAV-mobile phone dyad for 45 days post-discharge. The primary predictor is the deviation of transthoracic bioimpedance for 3 consecutive days from a patient-specific normal variability range. The ADHF detection algorithm is evaluated in relation with a composite outcome of HF readmission, diuretic up-titration, and self-reported HF worsening (Kansas City Cardiomyopathy Questionnaire) during a 90-day follow-up period. Here, we provide the details and rationale of SENTINEL-HF. Results Enrollment in the SENTINEL-HF study is complete and the 90-days follow-up is currently under way. Once data collection is complete, the study dataset will be used to evaluate our ADHF

    Six persons in the early to middle stages of dementia ("leaders") were trained in Resident-Assisted Montessori Programming (RAMP) to lead a reading activity for 22 persons with more advanced dementia ("participants") in an adult day health center (ADHC) and a special care unit (SCU) in a skilled nursing facility. Researchers assessed the leaders' abilities to learn and follow the procedures of leading a group, as well as their satisfaction with their roles. In addition, participants' engagement and affect were measured, both during standard activities programming and during client-led activities. Results of this study suggest that persons with dementia can indeed successfully lead small group activities, if several important prerequisites are met. Furthermore, the engagement and affect of participants was more positive in client-led activities than in standard activities programming. PMID:17533999

    Objective: Typically regarded as an adolescent condition, acne among adult females is also prevalent. Limited data are available on the clinical characteristics and burden of adult female acne. The study objective was to describe clinical characteristics and psychosocial impact of acne in adult women. Design: Cross-sectional, web-based survey. Setting: Data were collected from a diverse sample of United States females. Participants: Women ages 25 to 45 years with facial acne (≥25 visible lesions). Measurements: Outcomes included sociodemographic and clinical characteristics, perceptions, coping behaviors, psychosocial impact of acne (health-related quality of life using acne-specific Quality of Life questionnaire and psychological status using Patient Health Questionnaire), and work/productivity. Results: A total of 208 women completed the survey (mean age 35±6 years), comprising White/Caucasian (51.4%), Black/African American (24.5%), Hispanic/Latino (11.1%), Asian (7.7%), and Other (5.3%). Facial acne presented most prominently on cheeks, chin, and forehead and was characterized by erythema, postinflammatory hyperpigmentation, and scarring. Average age of adult onset was 25±6 years, and one-third (33.7%) were diagnosed with acne as an adult. The majority (80.3%) had 25 to 49 visible facial lesions. Acne was perceived as troublesome and impacted self-confidence. Makeup was frequently used to conceal acne. Facial acne negatively affected health-related quality of life, was associated with mild/moderate symptoms of depression and/or anxiety, and impacted ability to concentrate on work or school. Conclusion: Results highlight the multifaceted impact of acne and provide evidence that adult female acne is under-recognized and burdensome. PMID:24578779

  10. Investigate-and-redesign tasks as a context for learning and doing science and technology: A study of naive, novice and expert high school and adult designers doing product comparisons and redesign tasks

    This thesis studied high school students and adults with varying degrees of design experience doing two technology investigate-and-redesign (I&R) tasks. Each involved subjects investigating products, designing experiments to compare them fairly, and then redesigning the devices. A total of 25 pairs of subjects participated in this investigation and included naive and novice high school designers, as well as naive, novice, and expert adult designers. Subjects of similar age and design experience worked in same-gender teams and met for two 2-hour sessions. The essential research question of this thesis was: "What process skills and concepts do naive, novice and expert designers use and learn when investigating devices, designing experiments, and redesigning the devices?" Three methodologies were used to gather and analyze the data: clinical interviewing (Piaget, 1929/1960), protocol analysis (Ericsson & Simon, 1984) and interaction analysis (Jordan and Henderson, 1995). The thesis provides composite case-studies of 10 of the 50 test sessions, buttressed by descriptions of performance trends for all subjects. Given the small sample sizes involved, the findings are by necessity tentative and not supported by statistical analysis: (1) I&R activities are engaging, less time-intensive complements to design-and-build tasks, which involve simple mechanical devices and carry with them a host of potential "alternative understandings" in science and technology. Much gets learned during these tasks, more involving "device knowledge" and "device inquiry skills" than "big ideas" in science and technology. (2) Redesign tasks scaffold naive and novice designers to improved performance in the multidimensional and context-specific activity of design. The performances of naive and novice designers were more like that of expert designers when redesigning existing devices than when doing start-from-scratch designing. (3) Conceptual redesign involved more analysis- than synthesis

    Ethnic minority groups are less engaged than Caucasian American adults in advance care planning (ACP). Knowledge deficits, language, and culture are barriers to ACP. Limited research exists on ACP and advance directives in the Chinese American adult population. Using a pre-posttest, repeated measures design, the current study explored the effectiveness of a nurseled, culturally sensitive ACP seminar for Chinese American adults on (a) knowledge, completion, and discussion of advance directives; and (b) the relationship between demographic variables, advance directive completion, and ACP discussions. A convenience sample of 72 urban, community-dwelling Chinese American adults (mean age=61 years) was included. Knowledge, advance directive completion, and ACP discussions increased significantly after attending the nurse-led seminar (p<0.01). Increased age correlated with advance directive completion and ACP discussions; female gender correlated with ACP discussions. Nursing education in a community setting increased advance directive knowledge and ACP engagement in Chinese American adults. PMID:25912237

    The application of the best practices of teaching adults to the education of adults in medical education settings is important in the process of transforming learners to become and remain effective physicians. Medical education at all levels should be designed to equip physicians with the knowledge, clinical skills, and professionalism that are required to deliver quality patient care. The ultimate outcome is the health of the patient and the health status of the society. In the translational science of medical education, improved patient outcomes linked directly to educational events are the ultimate goal and are best defined by rigorous medical education research efforts. To best develop faculty, the same principles of adult education and teaching adults apply. In a systematic review of faculty development initiatives designed to improve teaching effectiveness in medical education, the use of experiential learning, feedback, effective relationships with peers, and diverse educational methods were found to be most important in the success of these programs. In this article, we present 5 examples of applying the best practices in teaching adults and utilizing the emerging understanding of the neurobiology of learning in teaching students, trainees, and practitioners. These include (1) use of standardized patients to develop communication skills, (2) use of online quizzes to assess knowledge and aid self-directed learning, (3) use of practice sessions and video clips to enhance significant learning of teaching skills, (4) use of case-based discussions to develop professionalism concepts and skills, and (5) use of the American Academy of Pediatrics PediaLink as a model for individualized learner-directed online learning. These examples highlight how experiential leaning, providing valuable feedback, opportunities for practice, and stimulation of self-directed learning can be utilized as medical education continues its dynamic transformation in the years ahead.

    Study Objectives: To examine sleep patterns and sleep problems and their relationship with daytime functioning in adults with a diagnosis of an autism spectrum disorder and no comorbid intellectual disability (high-functioning autism spectrum disorder [HFASD]) compared to neurotypical (NT) adults. Design: Cross-sectional. Setting: Home-based study. Participants: 36 adults with HFASD and 36 age-, intelligence quotient- and sex-matched NT adults. Measurements: Participants completed an online questionnaire battery including the Pittsburgh Sleep Quality Index (PSQI), a 14-d sleep wake diary and 14-d actigraphy data collection. Results: Adults with HFASD had significantly more general sleep disturbances and higher scores on the PSQI, longer sleep onset latencies (actigraphy), and poorer sleep efficiency (diary) and these results remained significant after accounting for the False Discovery Rate. Those adults with HFASD who did not have a comorbid diagnosis of anxiety/depression had significantly shorter total sleep time (diary and actigraphy) compared to NT adults. Compared to NT adults, the HFASD group self-reported significantly poorer refreshment scores upon waking in the morning and higher scores on the daytime dysfunction due to sleepiness subscale of the PSQI. Conclusions: These findings support the notion that problems related to sleep, in particular insomnia, continue into adulthood in individuals with high-functioning autism spectrum disorder.

  20. AggreSet: Rich and Scalable Set Exploration using Visualizations of Element Aggregations.

    Datasets commonly include multi-value (set-typed) attributes that describe set memberships over elements, such as genres per movie or courses taken per student. Set-typed attributes describe rich relations across elements, sets, and the set intersections. Increasing the number of sets results in a combinatorial growth of relations and creates scalability challenges. Exploratory tasks (e.g. selection, comparison) have commonly been designed in separation for set-typed attributes, which reduces interface consistency. To improve on scalability and to support rich, contextual exploration of set-typed data, we present AggreSet. AggreSet creates aggregations for each data dimension: sets, set-degrees, set-pair intersections, and other attributes. It visualizes the element count per aggregate using a matrix plot for set-pair intersections, and histograms for set lists, set-degrees and other attributes. Its non-overlapping visual design is scalable to numerous and large sets. AggreSet supports selection, filtering, and comparison as core exploratory tasks. It allows analysis of set relations inluding subsets, disjoint sets and set intersection strength, and also features perceptual set ordering for detecting patterns in set matrices. Its interaction is designed for rich and rapid data exploration. We demonstrate results on a wide range of datasets from different domains with varying characteristics, and report on expert reviews and a case study using student enrollment and degree data with assistant deans at a major public university.
