    Medical centers and biotechnology companies active in cellular and gene therapy increasingly are working to design and build clinical laboratories capable of performing cellular engineering and vector production using current good manufacturing practices (cGMPs). Because cell engineering is a rapidly changing field, and definitions for cell engineering cGMPs are still being established, a cGMP cell-engineering laboratory most often should be designed with a broad range of potential applications in mind. While the laboratory facility is the most tangible aspect of cGMP, it represents only part of a larger process, which it must be designed and built to support.

    2007-06-01

    Increasing levels of financial support for customer-sited photovoltaic (PV) systems, provided through publicly-funded incentive programs, has heightened concerns about the long-term performance of these systems. Given the barriers that customers face to ensuring that their PV systems perform well, and the responsibility that PV incentive programs bear to ensure that public funds are prudently spent, these programs should, and often do, play a critical role in ensuring that PV systems receiving incentives perform well. To provide a point of reference for assessing the current state of the art, and to inform program design efforts going forward, we examine the approaches to encouraging PV system performance used by 32 prominent PV incentive programs in the U.S. We identify eight general strategies or groups of related strategies that these programs have used to address performance issues, and highlight important differences in the implementation of these strategies among programs.

  7. Toward best practice in Human Machine Interface design for older drivers: A review of current design guidelines.

    Young, K L; Koppel, S; Charlton, J L

    2017-09-01

    Older adults are the fastest growing segment of the driving population. While there is a strong emphasis for older people to maintain their mobility, the safety of older drivers is a serious community concern. Frailty and declines in a range of age-related sensory, cognitive, and physical impairments can place older drivers at an increased risk of crash-related injuries and death. A number of studies have indicated that in-vehicle technologies such as Advanced Driver Assistance Systems (ADAS) and In-Vehicle Information Systems (IVIS) may provide assistance to older drivers. However, these technologies will only benefit older drivers if their design is congruent with the complex needs and diverse abilities of this driving cohort. The design of ADAS and IVIS is largely informed by automotive Human Machine Interface (HMI) guidelines. However, it is unclear to what extent the declining sensory, cognitive and physical capabilities of older drivers are addressed in the current guidelines. This paper provides a review of key current design guidelines for IVIS and ADAS with respect to the extent they address age-related changes in functional capacities. The review revealed that most of the HMI guidelines do not address design issues related to older driver impairments. In fact, in many guidelines driver age and sensory cognitive and physical impairments are not mentioned at all and where reference is made, it is typically very broad. Prescriptive advice on how to actually design a system so that it addresses the needs and limitations of older drivers is not provided. In order for older drivers to reap the full benefits that in-vehicle technology can afford, it is critical that further work establish how older driver limitations and capabilities can be supported by the system design process, including their inclusion into HMI design guidelines.

    rather than the rated capacity of the modules or system, are often suggested as one possible strategy. Somewhat less recognized are the many other program design options also available, each with its particular advantages and disadvantages. To provide a point of reference for assessing the current state of the art, and to inform program design efforts going forward, we examine the approaches to encouraging PV system performance - including, but not limited to, PBIs - used by 32 prominent PV incentive programs in the U.S. (see Table 1).1 We focus specifically on programs that offer an explicit subsidy payment for customer-sited PV installations. PV support programs that offer other forms of financial support or that function primarily as a mechanism for purchasing renewable energy credits (RECs) through energy production-based payments are outside the scope of our review.2 The information presented herein is derived primarily from publicly available sources, including program websites and guidebooks, programs evaluations, and conference papers, as well as from a limited number of personal communications with program staff. The remainder of this report is organized as follows. The next section presents a simple conceptual framework for understanding the issues that affect PV system performance and provides an overview of the eight general strategies to encourage performance used among the programs reviewed in this report. The subsequent eight sections discuss in greater detail each of these program design strategies and describe how they have been implemented among the programs surveyed. Based on this review, we then offer a series of recommendations for how PV incentive programs can effectively promote PV system performance.

    Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder. Macroanalysis is a helpful tool for identifying the relationships between biological and psychosocial variables and the individual targets for medical intervention. The personalized and holistic approach to the patient includes integration of medical and psychological therapies in all phases of illness. In this respect, the development of a new psychotherapeutic modality, Well-Being Therapy, seems to be promising. The growth of subspecialties, such as psychooncology and psychodermatology, drives towards the multidisciplinary organization of health care to overcome artificial boundaries. There have been major transformations in health care needs in the past decades. From psychosomatic medicine, a land of innovative hypotheses and trends, many indications for changes in the current practice of medicine are now at hand. The aim of this critical review is to outline current and potential clinical applications of psychosomatic methods. © 2016 S. Karger AG, Basel.

    Each time a practitioner creates or modifies an augmentative and alternative communication (AAC) display for a client, that practitioner must make a series of decisions about which vocabulary concepts to include, as well as physical and organizational features of the display. Yet, little is known about what factors influence the actual decisions and their outcomes. This research examined the design factors identified as priorities by speech-language pathologists (SLPs) when creating AAC displays for young children (age 10 years and under), and their rationale for the selection of these priorities. An online survey gathered ratings and comments from 112 SLPs with experience in AAC concerning the importance of a variety of factors related to designing an aided AAC display. Results indicated that some decisions were supported by existing research evidence, such as choosing vocabulary, collaborating with key stakeholders, and supporting partner modeling. Other decisions highlight areas for future research, including use of visual scene display layouts, symbol background color, and supports for motor planning.

    The didactic principle of exemplary learning may be defined briefly as 'learning by example'. In design education, working with a practical example is particularly appropriate, because design by definition is about creating a solution to a practical problem. Indeed, some design theorists claim...... that design knowledge and knowing is inseparable from practice, as in Donald Schön's suggestion that design education could be organized as a 'practicum' and based theoretically on an 'epistemology of practice'. However, the combination of exemplary learning and design studies does raise several questions......, including: If design knowing is bound to a given practical design context, how is it possible to generalize such knowing, as presumably required by an exemplary learning approach? To explore these questions, an account is given of the theories of exemplary learning proposed by Martin Wagenschein and Oskar...

LISA is unique from a mission design perspective in that the three spacecraft and their associated operations form one distributed science instrument. unlike more conventional missions where an instrument is a component of an individual spacecraft. The design of the LISA spacecraft is also tightly coupled to the design and requirements of the scientific payload; for this reason it is often referred to as a "sciencecraft." Here we describe some of the unique features of the LISA spacecraft design that help create the quiet environment necessary for gravitational wave observations.

    2016-11-23

    International research is an essential means of reducing health disparities between and within countries and should do so as a matter of global justice. Research funders from high-income countries have an obligation of justice to support health research in low and middle-income countries (LMICs) that furthers such objectives. This paper investigates how their current funding schemes are designed to incentivise health systems research in LMICs that promotes health equity. Semi-structured in-depth interviews were performed with 16 grants officers working for 11 funders and organisations that support health systems research: the Alliance for Health Policy and Systems Research, Comic Relief, Doris Duke Foundation, European Commission, International Development Research Centre, Norwegian Agency for Development Cooperation, Research Council of Norway, Rockefeller Foundation, UK Department of International Development, UK Medical Research Council, and Wellcome Trust. Thematic analysis of the data demonstrates their funding schemes promote health systems research with (up to) five key features that advance health equity: being conducted with worst-off populations, focusing on research topics that advance equitable health systems, having LMIC ownership of the research agenda, strengthening LMIC research capacity, and having an impact on health disparities. The different types of incentives that encouraged proposed projects to have these features are identified and classified by their strength (strong, moderate, weak). It is suggested that research funders ought to create and maintain funding schemes with strong incentives for the features identified above in order to more effectively help reduce global health disparities. © 2016 John Wiley & Sons Ltd.

    Full Text Available Deferoxamine (DFO is reference standard therapy for transfusional iron overload since the 1980s. Although it is a highly effective iron chelator, the compliance problem to subcutaneous administration of DFO remains as the major problem. The oral chelator Deferiprone (DFP has no marketing licence in North America, however, it has been licensed in India since 1994 and the European Union (EU granted marketing approval for DFP in 1999, specifically for patients with thalassemia major when DFO is inadequate, intolerable or unacceptable. There are still limited data available on the use of DFP in children between 6 and 10 years of age, and no data on DFP use in children under 6 years of age. Subsequently the oral chelator Deferasirox (DFX was approved by FDA and EMA for the treatment of patients with transfusional iron overload -older than 2 years of age- as first line therapy, in 2005 and 2006 respectively. The primary objective of iron chelation is to maintain body iron at safe levels at all times but once iron is accumulated, the objective of iron chelation is to reduce tissue iron to safe levels which is a slow process. The chelation regimen, dose and frequency of administration, of the chelator(s are mainly determined based on body iron burden, presence of myocardial iron and the transfusional iron loading rate. A proper monitoring of chelation is of importance for measuring the response rate to a particular regimen and providing dose adjustments to enhance chelation efficacy and to avoid toxicity. Efficacy of a chelation regimen may exhibit individual variability resulting from factors such as absorbtion and metabolism of the chelator. Tolerability and compliance are also individual variables effecting the response to chelation. Understanding of advantages and limitations of chelators, accurately determining chelation needs of patients with iron overload and designing individualized chelation regimens with less toxicity but optimum efficacy

Early optimal blood transfusion is essential to sustain organ perfusion and oxygenation. There are many variables to consider when establishing an MTP, and studies have prospectively evaluated different scenarios and patient populations to establish the best practices to attain improved patient outcomes. The establishment and utilization of an optimal MTP is challenging given the ever-changing patient status during resuscitation efforts. Much of the MTP literature comes from the trauma population, due to the fact that massive hemorrhage is the leading cause of preventable trauma-related death. As we come to further understand the positive and negative clinical impacts of transfusion-related factors, massive transfusion practice can be further refined. This article will first discuss specific MTPs targeting different patient populations and current relevant international guidelines. Then, we will examine a wide selection of therapeutic products to support MTPs, including newly available products and the most suitable of the traditional products. Lastly, we will discuss the best design for an MTP, including ratio-based MTPs and MTPs based on the use of point-of-care coagulation diagnostic tools.

    Electronic information processing is becoming a necessity in today's complex design environment, but what is an appropriate role for the computer in the design process Computation should be applied throughout all design phases, but practicing designers today rarely use computers beyond simple word processing and drafting tasks. While many design tasks are poorly matched to the computer, other pragmatic and productive avenues remain unexploited. We discuss the need to recognize which elements of the design process are most suited to computer assistance. The authors define a role for the computer as an objective assistant to the designer, and discuss practical approaches in two application areas for computers in design: design simulation and resource information management.

    To identify current operational practices and expectations for future practices in hospital foodservice; establish the probability that current practices will change; and determine whether differences in practices exist on the basis of profit status and hospital size. A questionnaire, to determine current practices, probability of change, and expectations for future practices, was mailed to foodservice directors. A random sample of 500 foodservice directors in US hospitals with 200 or more beds. A total of 214 questionnaires were returned for a response rate of 43%. Descriptive statistics were used to report current practices, probability of change, and expectations for future practices. The Kruskal-Wallis test was conducted to examine whether the probability of change ratings differed on the basis of hospital profit status and size. chi 2 Analysis was used to examine whether expectations for future practices differed based on hospital profit status and size. Currently 81% of hospital foodservice departments have fewer than 100 employees; 73% have revenue budgets of less than $2 million; 49% have expense budgets greater than $2 million; 55% use a selective menu, often (43%) 1-week in length; 74% use conventional food production technology; 81% have a centralized, hot tray line; 91% operate a cafeteria; 96% do on-site catering; 69% have differential pricing for employee meals; 58% have subsidized employee meals; and 19% have coffee kiosks. Changes in current practices are expected in several areas. Foodservice directors expect to serve meals to fewer inpatients (71%), employ less staff (73%), have smaller expense budgets (70%), and generate more revenue (61%). Kruskal-Wallis and chi 2 analyses indicated few differences on the basis of hospital profit status and size. There was little consensus among directors on how to best respond to these environmental changes. Hospital foodservice practices will change in the future.

    Physicians have long provided care free of charge or at a reduced rate as a professional courtesy to other physicians and their families. We conducted a stratified national mail survey to assess the extent to which this practice has changed in recent years. Using the American Medical Association's 1991 master list of physicians, we selected a random sample of 4800 practicing physicians from 12 direct-care specialties. These physicians were asked about their current policy and opinions regarding professional courtesy. Of the 2224 respondents, 2127 (96 percent) offered professional courtesy, defined as providing free or discounted health care to physicians and their families. Psychiatrists were less likely to offer professional courtesy than physicians in any of the other specialties (80 percent vs. 91 to 99 percent, P courtesy included billing only the insurance company (75 percent), providing care at no charge (49 percent), and giving a partial discount (23 percent). Twenty-three percent of the respondents reported that they had changed their policy regarding professional courtesy since starting to practice. Among those who had changed their policy, the most common changes were to increase the practice of billing only the insurance company (67 percent) and to provide care at no charge less often (58 percent). The majority of physicians responding to the survey thought that professional courtesy solidified bonds between physicians (79 percent) and was sound business practice (62 percent); 12 percent believed that it was too expensive to offer free or discounted care as a professional courtesy, and 14 percent thought that the practice had negative effects on the physician-patient interaction. Our survey of physicians involved in direct patient care indicates that, with the exception of psychiatrists, almost all American physicians offer free or discounted care as a professional courtesy and support the practice.

    1999-01-01

    The practice of music therapy in school settings was the focus of this study. Survey forms were mailed to 244 NAMT members who indicated school setting as their place of employment. A total of 190 forms were received, 138 of which fit the qualifications for inclusion and were included in the data summaries. Greater numbers of respondents lived in Texas (21), New York (17), and Michigan (11), and were employed full-time (60&percent;). Employers were more typically school systems (53&percent;) for the highest percentage of full-time respondents (80&percent;), and self-employers (25&percent;) for the highest percentage of part-time respondents (80&percent;). A considerably higher percentage of time was spent each week in direct service delivery (62&percent;) than in consultation (13&percent;), travel (18&percent;), documentation (11&percent;), or preparation (14&percent;). Over 40&percent; of the respondents had been music therapists for more than 8 years, but not necessarily in their current positions. Almost 40&percent; needed a valid teaching certificate for employment, while over 50&percent; currently held one. Respondents most frequently worked with persons who were developmentally disabled (80&percent;). The impact of employer and the inclusion movement on professional practice issues was discussed, as were possible trends in the practice of music therapy in school settings.

    Questions regarding the feasibility of using electrical impedance tomography (EIT) to detect breast cancer may be answered by building a sufficiently precise multiple frequency EIT instrument. Current sources are desirable for this application, yet no current source designs have been reported that have the required precision at the multiple frequencies needed. We have designed an EIT current source using an enhanced Howland topology in parallel with a generalized impedance converter (GIC). This combination allows for nearly independent adjustment of output resistance and output capacitance, resulting in simulated output impedances in excess of 2 Gohms between 100 Hz and 1 MHz. In this paper, the theoretical operation of this current source is explained, and experimental results demonstrate the feasibility of creating a high precision, multiple frequency, capacitance compensated current source for EIT applications.

    A fully functioning, painless shoulder joint is essential to maintain a healthy, normal quality of life. Disease of the rotator cuff tendons (RCTs) is a common issue that affects the population, increasing with age, and can lead to significant disability and social and health costs. RCT injuries can affect younger, healthy patients and the elderly alike, and may be the result of trauma or occur as a result of chronic degeneration. They can be acutely painful, limited to certain activities or completely asymptomatic and incidental findings. A wide variety of treatment options exists ranging from conservative local and systemic pain modalities, to surgical fixation. Regardless of management ultimately chosen, physiotherapy of the RCT, rotator cuff muscles and surrounding shoulder girdle plays an essential role in proper treatment. Length of treatment, types of therapy and timing may vary if therapy is definitive care or part of a postoperative protocol. Allowing time for adequate RCT healing must always be considered when implementing ROM and strengthening after surgery. With current rehabilitation methods, patients with all spectrums of RCT pathology can improve their function, pain and quality of life. This manuscript reviews current theories and practice involving rehabilitation for RCT injuries.

    While the basic principles of conventional solar cells are well understood, little attention has gone towards maximizing the efficiency of photovoltaic devices based on shift currents. By analysing effective models, here we outline simple design principles for the optimization of shift currents for frequencies near the band gap. Our method allows us to express the band edge shift current in terms of a few model parameters and to show it depends explicitly on wavefunctions in addition to standard band structure. We use our approach to identify two classes of shift current photovoltaics, ferroelectric polymer films and single-layer orthorhombic monochalcogenides such as GeS, which display the largest band edge responsivities reported so far. Moreover, exploring the parameter space of the tight-binding models that describe them we find photoresponsivities that can exceed 100 mA W-1. Our results illustrate the great potential of shift current photovoltaics to compete with conventional solar cells.

    2017-06-01

    Full Text Available The aim of the work is to identify current trends in impression management on the basis of sociological research and develop recommendations to managers, employees of personnel management services, social workers on peculiarities of impression management. The relevance of the article is in studying the strengthening desire of people to influence each other. Among the objectives of the influence the most common one is the desire to create a good impression on others. This point was chosen by 91 % of the respondents. However, the use of various impression management techniques is ambiguous in its consequences, and, therefore, can constitute significant risks for effective management and interpersonal interaction. At the present stage the conducted studies are mainly related to considering peculiarities of application of impression management techniques in narrow scientific and applied fields. The article proves the wide prevalence of the use of impression management techniques in the business sphere and informal environment, their high effectiveness and negative consequences of their application. Prospect for further research in this direction are development and implementation of practical systematic measures to overcome the negative consequences of using the tactics of impression management as well as improving their effectiveness.

    Colonoscopy in the elderly is a reliable practice of great diagnostic and management value. However, patient's age has long been considered to affect the success of the procedure, achieved when the cecum is intubated, there is a good view of the colon if preparation has been properly carried out, and the examination does not cause excessive discomfort or complications. Substantial improvements have been made to the latter two aspects, due to more widespread use of deep sedation with propofol and cardiocirculatory monitoring during the procedure. The aim of our work was to assess whether, in the everyday practice of an open-access, digestive endoscopy teaching center, staffed by various providers delivering screening for polyposis, age is still a limitation to the success of the procedure and whether appropriate measures have been taken to improve colonoscopy in geriatric patients. We analysed 1480 consecutive colonoscopies, of which 319 were performed in patients aged over 73 years. The examination was significantly less successful in this group of patients (88.1 vs 94.4, p=0.0001), but there were no major technical or use-related complications connected with administration of propofol for sedation purposes, despite lower doses to the elderly (2.2 ± 1.1 mg/kg total dose, mean 151 ± 72.4 mg vs 2.9 ± 1.3 mg/kg total dose, mean 199 ± 77.9 mg in younger patients, ppreparation was the main factor affecting the success of the procedure in elderly patients (OR 5.9, 95% CI 2.25-15.72; p=0.0003). Only body weight over 60 kg facilitated it (weight ≥ 60 kg, OR 0.46, 95% CI 0.26-0.83). In colonoscopy in the elderly, safety appears to be the primary concern and, good outcomes can be achieved, but sometimes at the expense of diagnostic accuracy. This could probably be improved through better pre- and post-procedure care, not currently differentiated between young and elderly patients.

  14. Current practice of antibiotic prophylaxis during elective laparoscopic cholecystectomy.

    Science.gov (United States)

    Macano, Caw; Griffiths, E A; Vohra, R S

    2017-03-01

    INTRODUCTION Current guidelines do not recommend antibiotic prophylaxis in elective laparoscopic cholecystectomy. Despite this, there is wide variation in antibiotic prophylaxis during cholecystectomy in population-based studies. The aim of this survey was to establish the current rationale for antibiotic prophylaxis in elective laparoscopic cholecystectomy. METHODS A short questionnaire was designed and disseminated across collaborators for a population-based study investigating outcomes following cholecystectomy and via the Association of Upper Gastrointestinal Surgeons, Researchgate and Surginet membership. RESULTS Responses were received from 234 people; 50.9% had no written policy for the use of prophylactic antibiotics in elective cholecystectomy; 5.6% never used antibiotics, while 30.8% always did and 63.7% selectively used antibiotics. Contamination with bile, stones and pus were scenarios in which antibiotics were most commonly used in selective practices to reduce infective complications. Interestingly, 87% of respondents would be happy to participate in a trial investigating the effectiveness of antibiotics in elective laparoscopic cholecystectomy where contamination has occurred. CONCLUSIONS The disparity between current practice and guidelines appears to arise because of a lack of evidence to show that antibiotics reduce surgical site infection following elective laparoscopic cholecystectomy where contamination has occurred. This question needs to addressed before practice will change.

    2014-01-01

    Background The impact of specialization on the practice of general surgery has not been characterized. Our goal was to assess general surgeons’ operative practices to inform surgical education and workforce planning. Study Design We examined the practices of general surgeons identified in the 2008 State Inpatient and Ambulatory Surgery Databases of the Healthcare Cost and Utilization Project (HCUP) for three US states. Operations were identified using ICD-9 and CPT codes linked to encrypted physician identifiers. For each surgeon, total operative volume and the percentage of practice comprised of their most common operation were calculated. Correlation was measured between general surgeons’ case volume and the number of other specialists in a health service area. Results There were 1,075 general surgeons who performed 240,510 operations in 2008. The mean operative volume for each surgeon was 224 annual procedures. General surgeons performed an average of 23 different types of operations. For the majority of general surgeons, their most common procedure comprised no more than 30% of total practice. The most common operations, ranked by the frequency that they appeared as general surgeons’ top procedure, included: cholecystectomy, colonoscopy, endoscopy, and skin excision. The proportion of general surgery practice comprised of endoscopic procedures inversely correlated with the number of gastroenterologists in the health service area (Rho = - 0.50, p = 0.005). Conclusions Despite trends toward specialization, the current practices of general surgeons remain heterogeneous. This indicates a continued demand for broad-based surgical education to allow future surgeons to tailor their practices to their environment. PMID:24210145

    Prevention of perioperative hypothermia decreases morbidity and mortality, as well as hospital costs. This study was conducted to evaluate the level of implementation of protocols in 3 tertiary Spanish University Hospitals. A survey among anaesthesiologists assessed estimated importance and clinical practice in terms of prevention of perioperative hypothermia. Results were compared depending on their experience. Ptotal of 116 anaesthesiologists answered the survey, of whom 48 (41.3%) were residents, 32 (27.6%) were staff with less than 10 years of experience, and 36 (31.1%) staff with 10 years or more of experience, In a 0-10 importance scale, prevention of hypothermia was scored 7.49±1,79, with no difference between groups (P=.58). Younger staff were more concerned of the end surgery temperature than other colleagues (P=.02). The most usual practice was a combination warming the intravenous fluids and an electric blanket (55%). Only 20% of the anaesthesiologists monitored temperature intra-operatively, even though 75% considered it an important parameter. No unit had a written protocol for prevention of perioperative hypothermia. Despite the absence of prevention protocols, the anaesthesiologists were aware of the importance maintaining a normal peri-operative temperature, but this awareness is still not enough to influence their perioperative management to diagnose and prevent hypothermia. A harmonisation of practice at local, regional and national level could improve this practice in the future. Copyright © 2014 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    The results of wrist arthroplasty for severely destroyed and painful wrists are generally good in pain reduction, increased grip strength, and upper limb function. The wrist range of motion is usually preserved but not improved. Implant survival seems better than it was with earlier implant designs; however, there are problems of carpal component loosening. Patient selection plays an important role, requiring experience, careful patient information, and discussing the pros and cons of arthroplasty and partial or total wrist arthrodesis.

    2017-10-01

    To review the currently available pharmacotherapies for obesity management with a particular focus on the United States. Narrative review based on literature searches and the latest prescribing information (up to July 2017). Obesity pharmacotherapies may assist those individuals who have obesity, or overweight with comorbidities, who have failed to maintain weight loss with lifestyle modifications alone (caloric restriction and increased physical activity). Currently approved options in the United States include phentermine for short-term use and five obesity pharmacotherapies that can be used long-term (orlistat, lorcaserin, phentermine-topiramate, naltrexone-bupropion, and liraglutide 3.0 mg). If the use of an obesity pharmacotherapy is indicated, treatment should be selected to provide the most appropriate option for each individual and their circumstances. Variables such as contraindications, individual comorbidities, patient choice, patient readiness to incorporate additional behavioral changes (e.g., alcohol prohibition), and cost should guide choices. Each of the obesity pharmacotherapies has advantages and disadvantages that can help guide treatment choice. Those receiving treatment may also have individual preferences based on factors such as administration route, frequency of dosing, and/or safety profile. In addition, some options may be particularly appropriate for patients with common obesity-related complications such as depression or diabetes. ©2017 American Association of Nurse Practitioners.

  9. Energy-conserving development regulations: current practice

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-01

    Almost every aspect of land development has an effect on energy use, from minute architectural details to broad considerations of urban density. Energy-efficiency depends in part on how development is planned and carried out. Conventional development regulations, such as zoning ordinances and subdivision regulations, can be adapted in many ways to promote energy conservation at the community level. This report is about energy-efficient site and neighborhood design. It examines recent experiences of local governments that have adopted new development regulations or amended existing ones to promote energy conservation, more efficient generation and distribution, or a switch to alternative, renewable sources. Although much has been written in recent years about saving energy through community design, actual experience in applying these new ideas is still limited. To date, most communities have focused their efforts on studying the problem, documenting consumption patterns, and writing reports and plans. Only a handful have amended their land-use controls for the express purpose of saving energy. This study identifies 13 of these pioneering communities, after undertaking a survey of over 1400 local, regional, and state planning agencies. It takes a look at their experiences, to learn what has been done, how well it has worked, and what problems have been encountered.

    Many rock climbers wear ill-fitting and excessively tight footwear during activity. However, there is insufficient evidence of the extent or harms of this practice. To investigate footwear use in rock climbers with a focus on issues surrounding fit. A cross-sectional study with active rock climbers of over one year of experience completing a survey on their activity and footwear. Additionally, the authors quantified foot and shoe lengths and sizes alongside demographic data. Ill-fitting and excessively tight footwear was found in 55 out of 56 rock climbers. Foot pain during activity was also commonplace in 91% of the climbers. A mean size reduction of almost 4 UK shoe sizes was found between the climbers' street shoe size and that of their climbing footwear using a calibrated foot/shoe ruler.

    New protocols for regenerative endodontic treatment along with the parallel development of tissue engineering technologies are changing traditional knowledge and treatment possibilities for young patients with pulp-affected permanent immature teeth. The regeneration and completion of apical root development in pathological situations such as these is a clinical challenge that traditional treatments have not so far been able to resolve with complete success. In clinical terms, the decision of whether to perform apexogenesis or apexification on an immature tooth is determined by whether the pulp tissue is vital or non-vital. Recent evidence and reports in the literature have questioned the old dogmas. In this respect, the ever growing scientific literature in this field makes it essential to compile a critical reflection and summary of everything that has been written to date, in order to understand the biological basis of current clinical advances and ensuing lines of future therapy. In this paper, we wish to give scientific coverage and background to more recent clinical and molecular advances described in the field of apical regeneration using stem cell therapy and their potentially key role in the future clinical success of new pulp regenerative protocols.

    Nijkamp, J W; Sebire, N J; Bouman, K; Korteweg, F J; Erwich, J J H M; Gordijn, S J

    2017-06-01

    Perinatal death (PD) is a devastating obstetric complication. Determination of cause of death helps in understanding why and how it occurs, and it is an indispensable aid to parents wanting to understand why their baby died and to determine the recurrence risk and management in subsequent pregnancy. Consequently, a perinatal death requires adequate diagnostic investigation. An important first step in the analysis of PD is to identify the case circumstances, including relevant details regarding maternal history, obstetric history and current pregnancy (complications are evaluated and recorded). In the next step, placental examination is suggested in all cases, together with molecular cytogenetic evaluation and fetal autopsy. Investigation for fetal-maternal hemorrhage by Kleihauer is also recommended as standard. In cases where parents do not consent to autopsy, alternative approaches such as minimally invasive postmortem examination, postmortem magnetic resonance imaging, and fetal photographs are good alternatives. After all investigations have been performed it is important to combine findings from the clinical review and investigations together, to identify the most probable cause of death and counsel the parents regarding their loss.

    2017-06-01

    Full Text Available Introduction. Although the incidence of cardiac arrest in children is much lower than in adults, the condition is still considered a major health problem with a very low chance for survival. As in adults, the timely provision of cardiopulmonary resuscitation (CPR in children is crucial. Current guidelines for CPR in children were published along with the guidelines for CPR in adults in 2015. As in previous years, they are based on consensus provided by International Liaison Committee on Resuscitation (ILCOR. Guidelines of particular ILCOR member councils may vary and reflect regional characteristic such as different access to health care, education methods or willingness of population to provide emergency assistance. Moreover, the conditions requiring CPR in children are characterized not only by different incidence, but also by aetiology or techniques used for different age groups. Therefore, emphasis is put on simplicity and feasibility as well as on consistency with adult guidelines to improve retention of the paediatric sequences. Nurses may be first rescuers not only in health care facilities. Better understanding of CPR guidelines might help them to improve their ability to detect conditions requiring CRP and also initiate and provide effective emergency care.

  17. Telehealth: current practices and future directions

    David, Yadin B.

    1996-02-01

    When we review the positive impact that the integration of ostensibly independent patient-care services have on the efficient management of quality care, education, and collaborative research, it is not surprising that telehealth deployment is on the rise. The forces that drive this phenomenon include: the need to manage the entire disease episode; the desire for wider geographically-distributed quality health care; the escalation of customer expectations; globalization of healthcare and its support services; an increase in patient and provider convenience; and the acceptance of the present technological community. At the Telehealth Center at the Texas Children's Hospital, current classifications of clinical applications are listed: (1) initial urgent evaluation of patients, (2) triage decisions and pretransfer arrangements, (3) medical and surgical follow-up and medication review, (4) consultation for primary care encounters, (5) real-time subspecialty care consultation and planning, (6) management of chronic diseases and conditions, (7) extended diagnostic work-ups, (8) review of diagnostic images, and (9) preventive medicine and patient education. The delivery of such services is associated with challenges and opportunities. As we move forward from limited data processing to an integrated communication system, from centralized main frame functions to personalized and location-independent workstations, and from hospitals to clinics and homecare, an increase in the minimum features provided by the equipment and the communication systems must accompany the widening variety of clinical applications. Future expansion of telehealth systems stands to revolutionize the delivery of services to the benefits of providers' networks, our economy, and patients through integration.

  18. Overview of current and alternative slaughter practices

    Directory of Open Access Journals (Sweden)

    Troeger K.

    2004-01-01

    Full Text Available The conventional cattle slaughtering process includes some critical stages where a dissemination of Specified Risk Material (SRM: brain, spinal cord within or onto the carcass and within the slaughterhouse environment can occur. These processes are captive bolt stunning, removal of the head and first of all carcass splitting (sawing the spine lengthways. Captive bolt (CB stunning results in massive brain tissue damage with bleeding, and in some cases brain tissue also emerges from the CB hole. As the heart is still functioning, there is a risk of brain tissue particles being transferred v i a the blood flow to heart and lungs or even in the whole carcass. This contamination risk is actually assessed to be low, but a continuing leakage of Central Nervous System (CNS material from the captive bolt aperture in the further slaughter process may lead to direct and indirect contamination of carcass, meat and equipment. Therefore alternative stunning methods like electrical stunning or concussion stunning are discussed. A further critical point is the treatment of the head. When the head is removed, the spinal cord is cut with a knife. There is a danger of cross contamination due to spinal protein that may adhere to the knife and because of liquid cerebralis, which leaks from the foramen occipitale magnum. Further head cleaning with hand-held hoses following skinning also includes the danger of cross contamination from cleaning water or aerosol. Therefore measures regarding the safe handling of head and harvesting of head meat are proposed. The most critical point in terms of contamination of the meat surface with SRM is the currently common practise of sawing the spine vertically in the middle with hand-guided belt-type saws. A m i x t u r e of sawing residues and rinsing water (“sawing sludge” collects in the housing of the saw, and if it contains infectious material this leads to contamination of the subsequent carcasses.

    1985-01-01

    As part of a review of the NASA Langley Research Center scientific and technical information program, 50 technical reports from industry, research institutions, and government agencies were systematically examined and analyzed to determine current usage and practice in regard to (1) typography, including composition method, type style, type size, and margin treatment; (2) graphic design, including layout and imposition of material on the page; and (3) physical media, including paper, ink, and binding methods. The results indicate that approximately 50 percent of the reports were typeset, 70 percent used Roman (serif) type, 80 percent used 10- or 11-point type for text, 60 percent used a ragged right-hand margin, slightly more than half used paragraph indentation, 75 percent used a single-column layout, 65 percent had one or more figures or tables placed perpendicular to (not aligned with) the text, and perfect binding was the most frequently used binding method.

  3. Soil Quality Impacts of Current South American Agricultural Practices

    Directory of Open Access Journals (Sweden)

    Ana B. Wingeyer

    2015-02-01

    Full Text Available Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, Uruguay, Argentina and southern Brazil. Unprecedented adoption of no-tillage as well as improved soil fertility and plant genetics have increased yields, but the use of purchased inputs, monocropping i.e., continuous soybean (Glycine max (L. Merr., and marginal land cultivation have also increased. These changes have significantly altered the global food and feed supply role of these countries, but they have also resulted in various levels of soil degradation through wind and water erosion, soil compaction, soil organic matter (SOM depletion, and nutrient losses. Sustainability is dependent upon local interactions between soil, climate, landscape characteristics, and production systems. This review examines the region’s current soil and crop conditions and summarizes several research studies designed to reduce or prevent soil degradation. Although the region has both environmental and soil resources that can sustain current agricultural production levels, increasing population, greater urbanization, and more available income will continue to increase the pressure on South American croplands. A better understanding of regional soil differences and quantifying potential consequences of current production practices on various soil resources is needed to ensure that scientific, educational, and regulatory programs result in land management recommendations that support intensification of agriculture without additional soil degradation or other unintended environmental consequences.

  4. An empirical study of software design practices

    Card, David N.; Church, Victor E.; Agresti, William W.

    1986-01-01

    Software engineers have developed a large body of software design theory and folklore, much of which was never validated. The results of an empirical study of software design practices in one specific environment are presented. The practices examined affect module size, module strength, data coupling, descendant span, unreferenced variables, and software reuse. Measures characteristic of these practices were extracted from 887 FORTRAN modules developed for five flight dynamics software projects monitored by the Software Engineering Laboratory (SEL). The relationship of these measures to cost and fault rate was analyzed using a contingency table procedure. The results show that some recommended design practices, despite their intuitive appeal, are ineffective in this environment, whereas others are very effective.

    As part of the project "Religious slaughter (DIALREL): improving knowledge and expertise through dialogue and debate on issues of welfare, legislation and socio-economic aspects", this paper discusses an evaluation of current practices during Halal and Shechita slaughter in cattle, sheep, goats and poultry. During religious slaughter, animals are killed with and without stunning by a transverse incision across the neck that is cutting the skin, muscles (brachiocephalic, sternocephalic, sternohyoid, and sternothyroid), trachea, esophagus, carotid arteries, jugular veins and the major, superficial and deep nerves of the cervical plexus. In this report, the restraint methods, stunning, neck cutting, exsanguination, slaughter techniques and postcut handling in the abattoir were assessed for religious slaughter. Information about the procedures used during religious slaughter in Belgium, Germany, Italy, the Netherlands, Spain, the UK, Turkey and Australia was collected by means of spot visits to abattoirs. To standardize the information gathered during the spot visits three guidelines were designed, one for each species, and translated into the national languages of the countries involved. The document included questions on the handling and restraint methods (stunning, neck cutting/exsanguination/slaughter techniques and postcut handling performed under religious practices) and for pain and distress of the animal during the restraint, neck cutting and induction to death in each abattoir. Results showed differences in the time from restraining to stun and to cut in the neck cutting procedures and in the time from cut to death. © 2013.

  14. REVIEW OF CURRENT PRACTICE IN CHARACTERIZATION AND MONITORING

    Energy Technology Data Exchange (ETDEWEB)

    M.A.Ebadian, Ph.D.

    2001-01-01

    Characterization and monitoring are important parts of environmental remediation of contaminated sites by the Department of Energy--Office of Environmental Management (DOE-EM). The actual remediation process often cannot begin or even be planned until characterization is complete. Monitoring is essential to verify the progress of remediation and of the waste stream. However, some contaminated sites are difficult, costly, or have a high exposure risk to personnel to characterize or monitor using the baseline technology or current practice. Therefore, development of new characterization and monitoring technologies is time-critical to remediate these sites. The main task of the Characterization, Monitoring, and Sensor Technology Crosscutting Program (CMST-CP) is to develop and deploy innovative characterization and monitoring technologies that improve performance and reduce personnel exposure, cost, and detection limits. However, to evaluate different proposals for new technologies to decide which ones to develop or deploy, it is necessary to compare their cost and performance to the baseline technology. The goal of this project is to facilitate the direct comparison of new technologies to the baseline technology by documenting the current practices for site characterization and monitoring at DOE sites and by presenting the information in an easy-to-use, concise database. The database will assist the CMST-CP and others in evaluating or designing new technologies by identifying the baseline technologies and describing their performance and cost. The purpose of this document is to report on the completion of this project and to describe the database. Section 2.0 describes the data assessment methodology. Section 3.0 presents the database and serves as a user manual. Section 4.0 lists the references used for each baseline technology in the database. The full references can be found in the Appendix.

    Ye, Lin

    2017-02-01

    The development of clinical implant dentistry was intensively affected by dental implant design improvement and innovation, which brought about new concept, even milestone-like changes of clinical protocol. The current improvements of dental implant design and their clinical importance could be highlighted as followings: 1) The implant apical design influences the implant preliminary stability in immediate implant. The apical 3-5 mm design of implant makes implant stable in immediate implant, because this part would be screwed into alveolar bone through fresh socket, the other part of implant could not be tightly screwed in the socket because of smaller implant diameter. Implant apical form, screw design, self-taping of apical part would be essential for immediate implant. 2) The enough preliminary stability of implant makes immediate prosthesis possible. When osseointegration does not occur, the implant stability comes from a mechanical anchorage, which depends on implant form, screw thread and self-taping design. 3) Implant neck design may have influence for soft tissue recession in esthetic zone. The implant with large shoulder would not be selected for the esthetic area. The platform design may be more favorable in the area. 4) The connection design between implant and abutment is thought a very important structure in implant long-term stability. Moose taper and "tube in tube" were well documented structure design in 20-year clinical practice in Peking University. 5) In last 15 years, the plenty studies showed the platform design of implant had positive influence in implant marginal bone level. Whatever in single implant restoration or multi-implant prosthesis. 6) The digital technology makes clinical work more precise and high-tech. This would be a trend in implant dentistry. New generation of chair-side digital computer-aided design/computer-aided manufacturing makes immediate prosthesis without conventional impression possible. 7) New abutment design have

    2016-01-01

    We propose the notion of material programming as a new practice for designing future interactive artifacts. Material programming would be a way for the interaction designer to better explore the dynamics of the materials at hand and through that familiarity be able to compose more sophisticated...... and complex temporal forms in their designs. As such it would blur the boundaries between programming and crafting these new smart and computational materials. We envision a material programming practice developed around physical tools (e.g. Fig 1) that draw on bodily skills and experiences (Fig 2) while...... enabling actions performed directly on the material with immediate effects (no program vs. execution mode). Finally, the tools would enable one layer of abstraction and as such encompass the potential of the computational materials but not that of possibly adjacent computers, which could run more complex...

    The primary goal of quarantine is to reduce the risk of introducing infectious diseases into established collections. Fish quarantine is inherently complex because of the variety of species, environmental requirements, and facilities. To examine current practices, questionnaires were submitted to 60 public zoos and aquaria, predominantly in North America. Questions reviewed system type (closed, flow-through), quarantine length, diagnostics, treatments, and cleaning and disinfection. Forty-two of the 60 institutions responded. Most institutions had separate quarantine protocols for freshwater teleosts, marine teleosts, and elasmobranchs. Ninety-five percent of institutions had a minimum quarantine period of 30 days or more. Sixty-four percent of institutions used isolated areas for some or all of their fish quarantine. Twenty-five percent had designated fish quarantine staff. All institutions used regular visual examinations to assess animal health. Fifty-four percent of the institutions carried out routine hands-on diagnostics on some fish; this was more common for elasmobranchs than teleosts. All institutions carried out necropsies on mortalities. Fifteen percent of institutions performed histopathology on almost all fresh mortalities; 54% percent performed histopathology on less than 10% of mortalities. Prophylactic treatments were common in closed systems, in particular, formalin immersion for teleosts, freshwater dips and copper sulfate immersion for marine teleosts, and praziquantel immersion for marine teleosts and elasmobranchs. Institutions using dips generally did so at the start or end of quarantine. Fenbendazole- and praziquantel-medicated foods were used commonly in teleosts, but dosages varied greatly. Cleaning and disinfection of systems and equipment increased in response to known pathogens. These results can be used to compare and discuss fish quarantine practices at display facilities in order to improve quarantine success.

    Full Text Available Abstract Introduction The importance of gender in understanding health practices and illness experiences is increasingly recognized, and key to this work is a better understanding of the application of gender relations. The influence of masculinities and femininities, and the interplay within and between them manifests within relations and interactions among couples, family members and peers to influence health behaviours and outcomes. Methods To explore how conceptualizations of gender relations have been integrated in health research a scoping review of the existing literature was conducted. The key terms gender relations, gender interactions, relations gender, partner communication, femininities and masculinities were used to search online databases. Results Through analysis of this literature we identified two main ways gender relations were integrated in health research: a as emergent findings; and b as a basis for research design. In the latter, gender relations are included in conceptual frameworks, guide data collection and are used to direct data analysis. Conclusions Current uses of gender relations are typically positioned within intimate heterosexual couples whereby single narratives (i.e., either men or women are used to explore the influence and/or impact of intimate partner gender relations on health and illness issues. Recommendations for advancing gender relations and health research are discussed. This research has the potential to reduce gender inequities in health.

    2015-12-01

    Today, dentists have a wide range of imaging modalities to choose from, the film based techniques, digital techniques, and the recent introduction of 3D volumetric or cone beam computed tomography (CBCT). The inherent design features of the new generation dental x-ray equipment has significantly improved over the years with no evidence of substandard x-ray units in operation. In dental facilities radiological workload is comparatively low, newer radiation equipments and accessories follow safety guidelines and employ better radiation protection measures for the patient and the operator. Dentists' knowledge and expertise in radiation protection measures is good, enabling them to carry out riskfree radiation procedures in their practice. Therefore, the present study is aimed at assessing the need for dosimeters in current dental scenario. 'Is there currently a significant risk from dental radiography to merit the use of personal dosimetery in dental practice. 'Dental health professionals (Oral radiologists) and radiographic assistants of fourteen dental colleges in Karnataka state participated in this questionnaire study. The questionnaire consisted of the following questions--the make, type, year of manufacture of radiographic machines used in their setup, number of radiographs made per day in the institution, type of receptors used, number of personnel at risk for radiation exposure, radiation protection measures used, regular monitoring by personal dosimeters, equivalent dosage readings for the past 12 months and whether the reading of thermoluminescent dosimeters (TLD) for any personnel had exceeded the recommended exposure value in the last 3 years. Dosimetry records of the radiology staff in the last three years shows doses no more than 1.50 mSv per year. The various institutions' dose (person mSv) was in the range of 3.70 mSv-3.90 mSv. Personal monitoring for Dentists can be omitted in the dental colleges since the estimated dose of oral radiologists

  13. Optimization design of the coil of the eddy current sensor

    2006-11-01

    An eddy current sensor is usually used to measure the departure of a shaft from its axes, in order to avoid destroying the system because of collision. The design of the coil as the sense organ of an eddy current sensor is to search a set of proper sizes (includes the outer radius, the inner radius and tallness of the coil) in which the quality factor and the grads of magnetic field strength is great as soon as possible but the length of the lead is not much long. So an optimization function is introduced here for efficient design. This function is direct ratio with the quality factor of the core and the magnetic grads product by the coil and inverse ratio with the lead length. The proportions of three parameters can be changed according to the instance. When the value of the function reaches the maximum, the sizes of coil are the anticipant optimal sizes and the integration capability of the coil is at the high-point. To search the maximum of the function, the genetic algorithm is adopted. The simulation result by Matlab proves the practicability of the method.

    The utilisation of good design practices in the development of complex health services is essential to improving quality. Healthcare organisations, however, are often seriously out of step with modern design thinking and practice. As a starting point to encourage the uptake of good design practices, it is important to understand the context of their intended use. This study aims to do that by articulating current health service development practices. Eleven service development projects carried out in a large mental health service were investigated through in-depth interviews with six operation managers. The critical decision method in conjunction with diagrammatic elicitation was used to capture descriptions of these projects. Stage-gate design models were then formed to visually articulate, classify and characterise different service development practices. Projects were grouped into three categories according to design process patterns: new service introduction and service integration; service improvement; service closure. Three common design stages: problem exploration, idea generation and solution evaluation - were then compared across the design process patterns. Consistent across projects were a top-down, policy-driven approach to exploration, underexploited idea generation and implementation-based evaluation. This study provides insight into where and how good design practices can contribute to the improvement of current service development practices. Specifically, the following suggestions for future service development practices are made: genuine user needs analysis for exploration; divergent thinking and innovative culture for idea generation; and fail-safe evaluation prior to implementation. Better training for managers through partnership working with design experts and researchers could be beneficial.

  3. Current issues in the design of clinical trials in IBD.

    2014-01-01

    Although the randomized controlled trial has become the standard for regulatory approval of new drugs and devices in inflammatory bowel disease (IBD), the components of effective trial design and implementation are still evolving. While induction and maintenance of remission are the ultimate goals in the treatment of IBD, the conduct of trials intended to measure these outcomes has varied substantially over time, as have the definitions of disease remission. Significant progress has been made in recent years towards understanding patient- and disease-related factors that are essential considerations in clinical trial design. However, questions remain regarding the best methods for assessing disease activity, and importantly for establishing trial end points that are clinically relevant and likely to affect meaningful long-term improvements in disease outcomes. This chapter will discuss the current 'best methods' in IBD trial design and introduce potential future concepts for improving the efficiency of clinical trials as well as their utility to inform clinical practice management. 2014 Nestec Ltd., Vevey/S.

  4. A practical approach to programmatic assessment design.

    Timmerman, A A; Dijkstra, J

    2017-12-01

    Assessment of complex tasks integrating several competencies calls for a programmatic design approach. As single instruments do not provide the information required to reach a robust judgment of integral performance, 73 guidelines for programmatic assessment design were developed. When simultaneously applying these interrelated guidelines, it is challenging to keep a clear overview of all assessment activities. The goal of this study was to provide practical support for applying a programmatic approach to assessment design, not bound to any specific educational paradigm. The guidelines were first applied in a postgraduate medical training setting, and a process analysis was conducted. This resulted in the identification of four steps for programmatic assessment design: evaluation, contextualisation, prioritisation and justification. Firstly, the (re)design process starts with sufficiently detailing the assessment environment and formulating the principal purpose. Key stakeholders with sufficient (assessment) expertise need to be involved in the analysis of strengths and weaknesses and identification of developmental needs. Central governance is essential to balance efforts and stakes with the principal purpose and decide on prioritisation of design decisions and selection of relevant guidelines. Finally, justification of assessment design decisions, quality assurance and external accountability close the loop, to ensure sound underpinning and continuous improvement of the assessment programme.

    Detailed, published surveys specific to Australian breast radiotherapy practice were last conducted in 2002. More recent international surveys specific to breast radiotherapy practice include a European survey conducted in 2008/2009 and a Spanish survey conducted in 2009. Radiotherapy techniques continue to evolve, and the utilisation of new techniques, such as intensity-modulated radiation therapy (IMRT), is increasing. This survey aimed to determine current breast radiotherapy practices across Australia. An online survey was completed by 50 of the 69 Australian radiation therapy treatment centres. Supine tangential beam whole breast irradiation remains the standard of care for breast radiotherapy in Australia. A growing number of institutions are exploring prone positioning and IMRT utilisation. This survey demonstrated a wide variation in the benchmarks used to limit and report organ at risk doses, prescribed dose regimen, and post-mastectomy bolus practices. This survey also indicated, when compared with international literature, that there may be less interest in or uptake of external beam partial breast irradiation, prone positioning, simultaneous integrated boost and breath hold techniques. These are areas where further review and research may be warranted to ensure Australian patients are receiving the best care possible based on the best evidence available.

    The current clinical practice of endodontics includes the utilization of a variety of new technological advances and materials. The last comprehensive survey that compared treatment modalities used in endodontic practices was conducted in 1990. The purpose of the current survey was to determine the frequency with which these new endodontic technologies and materials are being used in endodontic practices today. An e-mail questionnaire was sent to the 636 active diplomates of the American Board of Endodontics with current e-mail addresses. Two hundred thirty-two diplomates responded for a response rate of 35%. Calcium hydroxide was found to be the most frequently used intracanal medicament for all cases diagnosed with necrotic pulps. Ibuprofen was the most frequently prescribed medication for pain, and penicillin was the most frequently prescribed antibiotic when an active infection was present. Eighty-two percent of the respondents are still incorporating hand files in some fashion during the cleansing and shaping phase of treatment. Lateral condensation and continuous wave were the most common methods used for obturation. Digital radiography was reported as being used by 72.5% of the respondents, whereas 45.3% reported using the microscope greater than 75% of the patient treatment. Ultrasonics was used by 97.8% of the respondents. It appears from the results that new endodontic technology is currently being used in the endodontic offices of those who responded to the survey.

    Although occupational therapists have been practicing in forensic settings for many years, there is a paucity of literature regarding the nature of this practice in Canada. The purpose of this study was to describe the practices of Canadian occupational therapists in forensic mental health. An online survey was designed based on the Canadian Practice Process Framework. Following purposive and snowball sampling, responses were analysed with descriptive statistics and content analysis. Twenty-seven clinicians responded (56% response rate). Respondents indicated commonalities in workplaces, client caseloads and practice challenges. The outstanding need in Canada to demonstrate client outcomes through the use of evaluation instruments reflects those practice gaps identified internationally. Education, advocacy and research are critical areas for the development of Canadian forensic occupational therapy. Although findings heavily reflect one provincial context and may not be generalizable to nonhospital settings, a number of priority areas were identified. Future efforts should clarify the role of forensic occupational therapy to stakeholders, and validate their contributions through research that evaluates intervention efficacy and meaningful outcomes.

    Full Text Available Can video game design be compared to more formalized practices of scientific research or speculation within game studies? And, by virtue of an intellectual leap that in itself calls for discussion, can video games be considered as an efficient vehicle for the presentation of certain kinds of knowledge, in the same way in which papers, conference presentations, and books are? What Ratto defines as critical making (2011, the practice of producing artifacts of different sorts in order to supplement and extend critical reflection, may apply to video games as well. Forms of research through design (Zimmerman, Forlizzi and Evenson, 2007, of carpentry (Bogost, 2012, and speculative design (Dunne and Raby, 2013 have been analyzed, discussed, and maybe most importantly, put into practice in different fields of cultural and scientific production. To address this gap and to map the current (and future state of self-reflexive games, we asked both researchers and designers to imagine an application of these concepts to video games. Paraphrasing Zimmerman, Forlizzi and Evenson, what does research through game design might mean? What epistemological insights can we derive from the act of designing, making and playing video games?

    1994-01-01

    This tutorial summarizes reliability experience from both NASA and industry and reflects engineering practices that support current and future civil space programs. These practices were collected from various NASA field centers and were reviewed by a committee of senior technical representatives from the participating centers (members are listed at the end). The material for this tutorial was taken from the publication issued by the NASA Reliability and Maintainability Steering Committee (NASA Reliability Preferred Practices for Design and Test. NASA TM-4322, 1991). Reliability must be an integral part of the systems engineering process. Although both disciplines must be weighed equally with other technical and programmatic demands, the application of sound reliability principles will be the key to the effectiveness and affordability of America's space program. Our space programs have shown that reliability efforts must focus on the design characteristics that affect the frequency of failure. Herein, we emphasize that these identified design characteristics must be controlled by applying conservative engineering principles.

    The field of genomics is rapidly impacting medical care across specialties. To help guide test utilization and interpretation, pathologists must be knowledgeable about genomic techniques and their clinical utility. The technology allowing timely generation of genomic data is relatively new to patient care and the clinical laboratory, and therefore, many currently practicing pathologists have been trained without any molecular or genomics exposure. Furthermore, the exposure that current and recent trainees receive in this field remains inconsistent. To assess pathologists' learning needs in genomics and to develop a curriculum to address these educational needs. A working group formed by the College of American Pathologists developed an initial list of genomics competencies (knowledge and skills statements) that a practicing pathologist needs to be successful. Experts in genomics were then surveyed to rate the importance of each competency. These data were used to create a final list of prioritized competencies. A subset of the working group defined subtopics and tasks for each competency. Appropriate delivery methods for the educational material were also proposed. A final list of 32 genomics competency statements was developed. A prioritized curriculum was created with designated subtopics and tasks associated with each competency. We present a genomics curriculum designed as a first step toward providing practicing pathologists with the competencies needed to practice successfully.

    2014-01-01

    Pharmacogenomic studies have revealed a wide variation in the metabolism of codeine to its active metabolite, morphine. A particular subset of patients, known as ultrarapid metabolizers, possesses multiple copies of the CYP2D6 gene responsible for codeine metabolism. This has been linked to serious morbidity and mortality in pediatric patients leading to considerable debate regarding the use of codeine for analgesia in the pediatric population. The current study surveyed the current practice of codeine prescription in pediatric health care providers from a single tertiary care pediatric hospital. Of the 298 responders, 43.3% (129 of 298) continue to prescribe codeine for pain management in children. The vast majority of codeine prescribers were primary health care providers (89.1%). Most of the primary care practitioners were in office-based (42.6%) or hospital-based (45.7%) group practices. There was no significant difference in codeine use based on years of experience. Given the risks associated with this practice, increased education targeting this group appears warranted.

    Mental health reform in Brazil presupposes mental health becoming integrated into the Brazilian health system, involving multidisciplinary teams whose professional practice has yet to be defined. The present study forms part of a project aimed at understanding human resources practices in Brazilian mental healthcare services. This was a descriptive, exploratory study using a sample of highly qualified practitioners involved in the Ribeirao Preto/SP public mental health network. The project was approved by the Ribeirao Preto College of Nursing/University of Sao Paulo's ethics committee. A semi-structured questionnaire was used and the data was statistically analyzed. One hundred and forty-four of the 193 practitioners from the 8 public mental and psychiatric health care services agreed to participate. It was observed that current practice was mainly based on individual care, emphasizing medical, psychological and nursing care. Group activities were more frequently provided by community services. Mental care was infrequently prescribed and a low value was placed on activities like observation, recording and therapeutic interaction. Mental care services were being structured; however, practitioners still had difficulties in implementing current policy.

    2015-06-01

    The purpose of this study was to determine the current clinical practice in approaches to bimodal programming in the United States. To be specific, if clinicians are recommending bimodal stimulation, who programs the hearing aid in the bimodal condition, and what method is used for programming the hearing aid? An 11-question online survey was created and sent via email to a comprehensive list of cochlear implant programming centers in the United States. The survey was sent to 360 recipients. Respondents in this study represented a diverse group of clinical settings (response rate: 26%). Results indicate little agreement about who programs the hearing aids, when they are programmed, and how they are programmed in the bimodal condition. Analysis of small versus large implant centers indicated small centers are less likely to add a device to the contralateral ear. Although a growing number of cochlear implant recipients choose to wear a hearing aid on the contralateral ear, there is inconsistency in the current clinical approach to bimodal programming. These survey results provide evidence of large variability in the current bimodal programming practices and indicate a need for more structured clinical recommendations and programming approaches.

  1. Are social theories still relevant in current psychiatric practice?

    2016-01-01

    Full Text Available Current psychiatric practice is being influenced by advances in the field of molecular biology, genetic studies, neuroimaging, and psychopharmacology and the approach has become "biological." Social theories of mental illness had once revolutionized the field of psychiatry and are currently being somewhat ignored under the dazzle of biological sciences. Main social theories are functionalism, interpersonal theory, attachment theory, stress theory, and labeling theory. Each of these theories had tried to explain the genesis of psychiatric disorders in their own way. However, each theory has its own limitations and critique. Still, for a holistic approach to treat persons with mental illness, it is essential to take a biopsychosocial approach which can only be done if one understands the contribution and relevance of social theories. Nonpharmacological management has been the cornerstone of treatment of any psychiatric disorder and social theories also form the basis of various nonpharmacological modes of treatment. Overall, social theories are still very relevant in current psychiatric practice and should not be neglected. Efforts should be made to integrate social theories with other theories of mental illness for better understanding and treatment.

    The objective of this article is to discover and document the state of clinical practices for aphasia therapy in Finland and to gather information for developing national best practice. Two surveys were administered in Finland that explored current clinical practices in aphasia rehabilitation and the resources available to speech and language therapists (SLTs). We integrated and compared the results of these surveys. The results are based on the responses of the 88 (45 + 43) returned questionnaires from SLTs. Four principle themes were identified: planning the aphasia therapy, measures and assessment methods, current therapy service provision, and development suggestions and barriers to change. The results of this study showed considerable consistency in clinical practices among the respondents to the surveys. However, we noticed that there are some discrepancies between the recent research findings and present clinical practices. The findings from this study indicate that there are many challenges in clinical decision-making at the moment in Finland. The article helps clinicians to evaluate the practices they use and to execute justified modifications in order to implement more effective models of practice. It is evident that national best practice guidelines for aphasia therapy would support SLTs in clinical decision-making. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available The article deals with the theoretical and methodological underpinnings of best practice research (BPR. First, the basic components of BPR are formulated and analyzed. Then two different approaches to BPR are reviewed and their pros and cons discussed. Then the general problems of BPR are considered along with the possible ways of getting over them. The article shows that currently there is nothing like a “best practice of best practice research” and argues that much has to be done in the development of BPR theory and methodology. It concludes with several recommendations for improvement (mixed research design, clear definition of purpose, focus upon mechanisms etc.

    2014-08-01

    Full Text Available The essay deals with drawing as a genuine form of knowledge in architectural design. Drawing is described as an epistemic practice enmeshed with historically changing, material spaces of knowledge.Starting with a brief examination of historic philosophical positions on the epistemicity of drawing, the essay tries to sketch out a tentative heuristic of the epistemic features of drawing from the perspective of symbol and media theory.In the last part, with reference to Nelson Goodman’s distinction between analogue and digital symbol systems, the digitalization of drawing is critically reviewed. The main point is to emphasize that the transformation of drawing into digital drawing formats always consist of a translation.It is crucial to take the challenges stemming from the indeterminacy of translation (W.v.O. Quine into consideration in order to understand both the epistemic restrictions and the potentials of drawing under the conditions of the rising digital habitat.

    2015-01-01

    Here we present a high performance spring-type piezoelectric energy harvester that selectively collects current from the inner part of a spring shell. We analyzed themain reason behind the low efficiency of the initial design using finite element models and proposed a selective current collecting design that can considerably improve the electrical conversion efficiency of the energy harvester. We found that the newly designed energy harvester increases the output voltage by 8 times leading to an output power of 2.21 mW under an impulsive load of 2.18 N when compared with the conventional design. We envision that selective current collecting design will be used in spring-based self-powered active sensors and energy scavenging devices.

    2009-09-01

    In this study, we investigated current personality assessment practice and attitudes toward Rorschach (Exner, 2003) usage by 215 psychologists. We administered an Internet survey to members of the Society for Personality Assessment (SPA) and the American Psychological Association. Results were similar to those of past surveys, but the importance of using tests with strong psychometric properties was greater in this study. The majority of respondents reported using the Rorschach and supporting efforts to standardize and psychometrically validate the test. However, SPA members agreed more strongly than non-SPA members that the Rorschach is an effective test. Implications and directions for future research are discussed.

    2013-05-01

    Full Text Available This paper provides a review of current practice in relation to individual performance management systems and process within the traditional business environment. There is a consensus that the role of the individual is central to the overall performance of any organization and how individual performances are managed and evaluated can have significant impacts on overall organizational success. Many organizations employ the traditional performance appraisal in order to monitor and assess individual employee performances. However, new approaches, such as 360-degree feedback have also become commonplace within the business environment. An analysis of each approach including benefits and challenges associated with each process is presented within this paper.

    2017-02-01

    In this practical review, we discuss current surgical techniques reported in the literature to perform intracorporeal urinary diversion (ICUD) after robotic radical cystectomy (RARC), emphasizing criticisms of single approaches and making comparisons with extracorporeal urinary diversion (ECUD). Although almost 97% of all RARCs use an ECUD, ICUD is gaining in popularity, in view of its potential benefits (i.e., decreased bowel exposure, etc.), although there are a few studies comparing ICUD and ECUD. Analyzing single experiences and the data from recent metanalyses, we emphasize the current critiques to ICUD, stressing particular technical details which could reduce operative time, lowering the postoperative complications rate, and improving functional outcomes. Only analysis of long-term follow-up data from large-scale homogeneous series can ascertain whether robotic intracorporeal urinary diversion is superior to other approaches.

    2017-09-01

    Conduction cooled current leads, which bring the current from the room temperature terminal down to the cryogenic environment, were used in common recently in large scale superconducting accelerators for its low cost, sample design and low heat load. In practice, the current lead is designed contained in a stainless steel tube. The heat load can be incepted in steps by thermal anchors, where one end is attached to the stainless steel tube, while the other end is connected with the cold shield of the cryomodule. Since the limitation of the welding technique, a thicker stainless steel tube needs to be used, and hence the thermal anchors cannot provide enough pressure to deform the tube enough to be in direct contact with the current lead, which may lead to temperature instability and bring extra heat load to the cryogenic system. An excellent option of epoxy filled current lead can realize the fully contact and reduce the heat load effectively. This paper will present the process of the current lead design, optimization, numerical simulation and cryogenic test, the test results show that the current lead can keep in a stable operation and low heat load.

  16. High-Average, High-Peak Current Injector Design

    CERN Document Server

    Biedron, S G; Virgo, M

    2005-01-01

    There is increasing interest in high-average-power (>100 kW), um-range FELs. These machines require high peak current (~1 kA), modest transverse emittance, and beam energies of ~100 MeV. High average currents (~1 A) place additional constraints on the design of the injector. We present a design for an injector intended to produce the required peak currents at the injector, eliminating the need for magnetic compression within the linac. This reduces the potential for beam quality degradation due to CSR and space charge effects within magnetic chicanes.

    Gharib, H; Papini, E; Paschke, R

    2008-11-01

    In 2006, two major society-sponsored guidelines and one major consensus statement for thyroid diagnosis and management were published by: the American Association of Clinical Endocrinologists/Associazione Medici Endocrinologi (AACE/AME); the American Thyroid Association (ATA); and the European Thyroid Association (ETA). A careful review of these guidelines reveals that despite many similarities, significant differences are also present, likely reflecting differences in practice patterns, interpretation of existing data, and availability of resources in different regions. The methodology of the guidelines is similar, but a few differences in the rating scale make a rapid comparison of the strength of both evidence and recommendations difficult for the use in current clinical practice. Some recommendations are based mostly on experts' opinion. Thus, a same recommendation may be based on a different evidence; on the other hand, sometimes the same evidence may induce a different recommendation. Therefore, efforts are needed to produce a few high-quality clinical studies to close the evidence gaps in the still controversial fields of thyroid disease and to create a joint task force of the most authoritative societies in the field of thyroid disease in order to reach a common document for clinical practice recommendations.

    2007-11-01

    Full Text Available Abstract Background Most clinical trial publications include figures, but there is little guidance on what results should be displayed as figures and how. Purpose To evaluate the current use of figures in Trial reports, and to make constructive suggestions for future practice. Methods We surveyed all 77 reports of randomised controlled trials in five general medical journals during November 2006 to January 2007. The numbers and types of figures were determined, and then each Figure was assessed for its style, content, clarity and suitability. As a consequence, guidelines are developed for presenting figures, both in general and for each specific common type of Figure. Results Most trial reports contained one to three figures, mean 2.3 per article. The four main types were flow diagram, Kaplan Meier plot, Forest plot (for subgroup analyses and repeated measures over time: these accounted for 92% of all figures published. For each type of figure there is a considerable diversity of practice in both style and content which we illustrate with selected examples of both good and bad practice. Some pointers on what to do, and what to avoid, are derived from our critical evaluation of these articles' use of figures. Conclusion There is considerable scope for authors to improve their use of figures in clinical trial reports, as regards which figures to choose, their style of presentation and labelling, and their specific content. Particular improvements are needed for the four main types of figures commonly used.

    2013-09-01

    In an effort to share best practices in undergraduate engineering design education, we describe the origin, evolution and the current status of the undergraduate biomedical engineering design team program at Johns Hopkins University. Specifically, we describe the program and judge the quality of the pedagogy by relating it to sponsor feedback, project outcomes, external recognition and student satisfaction. The general pedagogic practices, some of which are unique to Hopkins, that have worked best include: (1) having a hierarchical team structure, selecting team leaders the Spring semester prior to the academic year, and empowering them to develop and manage their teams, (2) incorporating a longitudinal component that incudes freshmen as part of the team, (3) having each team choose from among pre-screened clinical problems, (4) developing relationships and fostering medical faculty, industry and government to allow students access to engineers, clinicians and clinical environments as needed, (5) providing didactic sessions on topics related to requirements for the next presentation, (6) employing judges from engineering, medicine, industry and government to evaluate designs and provide constructive criticisms approximately once every 3-4 weeks and (7) requiring students to test the efficacy of their designs. Institutional support and resources are crucial for the design program to flourish. Most importantly, our willingness and flexibility to change the program each year based on feedback from students, sponsors, outcomes and judges provides a mechanism for us to test new approaches and continue or modify those that work well, and eliminate those that did not.

  4. Permaculture Design: On the Practice of Radical Imagination

    Directory of Open Access Journals (Sweden)

    Katja Rothe

    2014-09-01

    Full Text Available Permaculture design is a concept that aims at transforming not only agriculture, but also city planning, architecture, development, etc. In short it aims to change human habitats. It is part of a new ecological paradigm that is currently spreading in popularity from the urban gardening movement to various other alternative movements such as the slow movement, sustainable architecture, etc. Permaculture design defines itself as building on systems theory (as formulated in particular by Howard Thomas Odum and Christopher Alexander. However I would like to propose that the afterlife of systems theory as expressed in the concept of permaculture, first developed by Bill Mollison and David Holmgren, should not only be sought in theoretical and analytical discourse. Instead we can understand permaculture as a form of figurative, ecological reasoning; a form of radical imagination drawn from the composite knowledge of a heterogeneous network of actors. Permaculture is thus neither a branch of environmental science nor an environmental political movement. Rather the philosophy of permaculture design questions the division between theory and practice or between rationality and sensibility. In permaculture design, these modes of knowledge are inextricably linked in explorations of patterns. In this article, I attempt to delineate the ways in which permaculture design is rooted in the practical knowledge of systems. I shall limit myself to exploratory drilling, as it were, in three aspects of permaculture design thought. First, I describe permaculture thought as a form of practical knowledge that generated through a kind of visual thinking in patterns. Second, I describe permaculture thought as a type of thinking in which radical imagination and speculation play an active role. Third, I present permaculture thought as systems theory thought. However it departs from the idea of control inherent to systems theory, drawing instead from the equally popular (and

  5. The emergence of thanatology and current practice in death education.

    Science.gov (United States)

    Fonseca, Luciana Mascarenhas; Testoni, Ines

    Thanatology is a recent field that contemplates death studies and employs an interdisciplinary approach to practice. This science emerged in a historical context marked by intense social, economic, and political changes that contributed to the concept of death being excluded from social life. This literature review aims to outline the history and evolution ofthanatology in Western society, delineating the contextual circumstances that led to its origin and drawing special attention to current works on death education. In our post-modern society, the call for studies in the field of thanatology appears to be increasing. However, although there have been significant contributions and promising research is underway, there are still many questions to be answered.

    Shields, Nora; Gormley, John; O'Hare, Neil

    2002-01-01

    Short-wave diathermy (SWD) is widely available, yet a comprehensive examination of current clinical practice remains absent from the literature. The present paper aims to assess clinical and safety issues in continuous (CSWD) and pulsed (PSWD) short-wave diathermy application and subsequently indicate areas for future research. A postal survey was carried out among 116 senior physiotherapists in 41 Irish hospital-based physiotherapy departments. The response rate to the study was 75%. Analysis found that PSWD was the preferred mode of treatment with 27% of respondents using it more than once daily. Respondents considered both modes of treatment indicated for a variety of conditions. CSWD was rated as an effective treatment for chronic osteoarthritis, polyarthritis, non-specific arthrosis and haematomas. PSWD was reported an effective modality for acute soft tissue injury, haematomas, acute osteoarthritis, sinusitis and rheumatoid arthritis. Dose selection varied greatly but tended to be based on the type, nature and duration of the condition. Analysis of safety practices uncovered concerning findings. Although a high level of agreement was found on measures for patient safety, 30% of respondents reported that no measures for operator safety were taken and only five respondents stated they remained a specified distance from SWD equipment. Measures to ensure the safety of other personnel in the physiotherapy department were also lacking. Given the availability of SWD equipment and its apparent efficacy in certain conditions, future research should aim to establish this by means of controlled clinical trials. The findings on safety practices underline the urgent need for comprehensive guidelines to ensure the safety of operators, patients and the general public during SWD application.

  9. Complementary feeding practices: Current global and regional estimates.

    2017-10-01

    Insufficient quantities and inadequate quality of complementary foods, together with poor feeding practices, pose a threat to children's health and nutrition. Interventions to improve complementary feeding are critical to reduce all forms of malnutrition, and access to data to ascertain the status of complementary feeding practices is essential for efforts to improve feeding behaviours. However, sufficient data to generate estimates for the core indicators covering the complementary feeding period only became available recently. The current situation of complementary feeding at the global and regional level is reported here using data contained within the UNICEF global database. Global rates of continued breastfeeding drop from 74.0% at 1 year of age to 46.3% at 2 years of age. Nearly a third of infants 4-5 months old are already fed solid foods, whereas nearly 20% of 10-11 months old had not consumed solid foods during the day prior to their survey. Of particular concern is the low rate (28.2%) of children 6-23 months receiving at least a minimally diverse diet. Although rates for all indicators vary by background characteristics, feeding behaviours are suboptimal even in richest households, suggesting that cultural factors and poor knowledge regarding an adequate diet for young children are important to address. In summary, far too few children are benefitting from minimum complementary feeding practices. Efforts are needed not only to improve children's diets for their survival, growth, and development but also for governments to report on progress against global infant and young child feeding indicators on a regular basis. © 2017 John Wiley & Sons Ltd.

  10. Current nursing practice by hospital-based stoma specialist nurses.

    Science.gov (United States)

    Burch, Jennie

    Nurses frequently care for patients who have stomas. A common complication is sore peristomal skin (skin around the stoma). The study aim was to answer the research question: what is the current nursing practice for peristomal skin problems among UK stoma specialist nurses? The question was explored through investigation of descriptions, treatments and opinions of peristomal skin problems. Results were examined to ascertain if practice reflects the literature and if care was evidence-based. A questionnaire was posted in September 2009 to the stoma care nurses in all UK NHS hospitals (n=596). The proportion of completed or partially completed questionnaires was 15% (89 of 596). Most of the responding nurses held a stoma-related qualification (86%), a degree (55%) and had specialised in stoma care for over 5 years (67%). Respondents used erythema to describe sore skin (80%). Stoma powder (98%) and convex appliances (98%) were the most commonly used treatments. The most common cause of sore skin was appliance leakage (61%). The study population was deemed suitably qualified and experienced to answer the research question. Many responses were reflected in the literature (predominantly opinion articles), reflecting a degree of reliability and validity. It could be concluded that stoma specialist nurses can accurately assess and use stoma accessories to treat sore skin, but due to the paucity of research, the care cannot be defined as evidence-based. More research is needed to determine universally accepted definitions and treatments for sore peristomal skin.

    Science.gov (United States)

    Candel, Francisco Javier; Julián-Jiménez, Agustin; González-Del Castillo, Juan

    2016-04-01

    Outpatient parenteral antimicrobial therapy (OPAT) programs are a current and widely spread trend in clinical practice because of it's a cost-effective option, it's associated with a greater comfort for the patient, a lower risk of nosocomial complications and an important cost saving for the health care system. OPAT is used for treating a wide range of infections, including skin and soft tissue infections, osteoarticular infections, bacteraemia, endocarditis and complex intra-abdominal and urinary tract infections, even in presence of multiresistant microorganisms. Correct choice of antimicrobial agent and adequate patient selection are crucial for reaching therapeutic success and avoiding readmissions, treatment prolongation or treatment-related toxicity. The optimal antimicrobial for OPAT must be highly effective, have a long half-life and an adequate spectrum of action. Ceftriaxone and teicoplanin are currently the most prescribed antibiotics for OPAT, though daptomycin and ertapenem are also on the rise, due to their high efficiency, safety and wide spectrum of action. Antibiotics that are stable at room temperature can be administered through a continuous perfusion, though self-administration is preferable although it requires training of the patient or the caregiver. Factors that are most frequently associated with OPAT failure include advanced age, recent hospitalization and isolation of multiresistant microorganisms.

  16. SECOND LANGUAGE VOCABULARY ASSESSMENT: CURRENT PRACTICES AND NEW DIRECTIONS

    Directory of Open Access Journals (Sweden)

    John Read

    2007-12-01

    Full Text Available This paper surveys some current developments in second language vocabulary assessment, with particular attention to the ways in which computer corpora can provide better quality information about the frequency of words and how they are used in specific contexts. The relative merits of different word lists are discussed, including the Academic Word List and frequency lists derived from the British National Corpus. Word frequency data is needed for measures of vocabulary size, such as the Yes/No format, which is being developed and used for a variety of purposes. The paper also reviews work on testing depth of knowledge of vocabulary, where rather less progress has been made, both in defining depth as a construct and in developing tests for practical use. Another important perspective is the use of vocabulary within particular contexts of use or registers, and recent corpus research is extending our understanding of the lexical features of academic registers. This provides a basis for assessing learners’ ability to deploy their vocabulary knowledge effectively for functional communication in specific academic contexts. It is concluded that, while current tests of vocabulary knowledge are valuable for certain purposes, they need to be complemented by more contextualised measures of vocabulary use.

    This study builds on the authors' previous studies that demonstrate that persons living with a colostomy who practice colostomy irrigation (CI) experience quality-of-life benefits. Studies also reveal that patients may not be taught about CI. The purpose of this study was to determine current knowledge, attitudes, and practices of WOC nurses on CI. The target population was ostomy nurses who were members of the Wound, Ostomy and Continence Nurse's Society. Nine hundred eighty-five nurses out of a possible pool of 4191 members responded, providing a response rate of 24%. Their average age was 53 years (range, 25-79 years). Respondents averaged 12 years' experience as a WOC nurse (range, 1-40 years) and 90% (n = 875) were certified. Participants practiced in a variety of settings, including acute and long-term care facilities, home health, and ambulatory clinics. They saw an average of 37 ± 60.5 (mean ± SD) ostomy patients per year (range, 0-1100). A 1-time online survey (SurveyMonkey) of members of the Wound, Ostomy and Continence Nurses (WOCN) Society was conducted. In addition to demographic and educational information, questions also included (1) CI advantages and disadvantages; (2) CI content routinely taught; (3) challenges in assisting patients to learn CI; and (4) where preparation was received for teaching this procedure. Nurses were asked whether they believe CI is evidence-based. More than half identified irrigation as an evidence-based practice (59%), but half indicated they do not routinely teach CI. Multiple factors correlated with nurses' decisions to teach CI, including years of experience (P = .03), specific CI education (P < .001), and considering the intervention evidence-based (P < .001). Factors influencing CI instruction are multifactorial; they include nurses' attitudes, experience base, education, medical indications, setting characteristics, and patient interest and physical abilities. Education on this procedure is urgently needed for

    Overweight and obesity affects approximately 20% of Australian pre-schoolers. The general practice nurse (PN) workforce has increased in recent years; however, little is known of PN capacity and potential to provide routine advice for the prevention of child obesity. This mixed methods pilot study aims to explore the current practices, attitudes, confidence and training needs of Australian PNs surrounding child obesity prevention in the general practice setting. PNs from three Divisions of General Practice in New South Wales were invited to complete a questionnaire investigating PN roles, attitudes and practices in preventive care with a focus on child obesity. A total of 59 questionnaires were returned (response rate 22%). Semi-structured qualitative interviews were also conducted with a subsample of PNs (n = 10). Questionnaire respondent demographics were similar to that of national PN data. PNs described preventive work as enjoyable despite some perceived barriers including lack of confidence. Number of years working in general practice did not appear to strongly influence nurses' perceived barriers. Seventy per cent of PNs were interested in being more involved in conducting child health checks in practice, and 85% expressed an interest in taking part in child obesity prevention training. Findings from this pilot study suggest that PNs are interested in prevention of child obesity despite barriers to practice and low confidence levels. More research is needed to determine the effect of training on PN confidence and behaviours in providing routine healthy life-style messages for the prevention of child obesity. © 2013 The Authors.

    To investigate current practices and timing of neurological prognostication in comatose cardiac arrest patients. An anonymous questionnaire was distributed to the 8000 members of the European Society of Intensive Care Medicine during September and October 2012. The survey had 27 questions divided into three categories: background data, clinical data, decision-making and consequences. A total of 1025 respondents (13%) answered the survey with complete forms in more than 90%. Twenty per cent of respondents practiced outside of Europe. Overall, 22% answered that they had national recommendations, with the highest percentage in the Netherlands (>80%). Eighty-nine per cent used induced hypothermia (32-34 °C) for comatose cardiac arrest patients, while 11% did not. Twenty per cent had separate prognostication protocols for hypothermia patients. Seventy-nine per cent recognized that neurological examination alone is not enough to predict outcome and a similar number (76%) used additional methods. Intermittent electroencephalography (EEG), brain computed tomography (CT) scan and evoked potentials (EP) were considered most useful. Poor prognosis was defined as cerebral performance category (CPC) 3-5 (58%) or CPC 4-5 (39%) or other (3%). When prognosis was considered poor, 73% would actively withdraw intensive care while 20% would not and 7% were uncertain. National recommendations for neurological prognostication after cardiac arrest are uncommon and only one physician out of five uses a separate protocol for hypothermia treated patients. A neurological examination alone was considered insufficient to predict outcome in comatose patients and most respondents advocated a multimodal approach: EEG, brain CT and EP were considered most useful. Uncertainty regarding neurological prognostication and decisions on level of care was substantial. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  6. Current Design Criteria for MMOD Impact of Metallic Pressurized Tanks

    Schonberg, William P.; Hull, Scott M.

    2016-01-01

    Most spacecraft have at least one pressurized vessel on board. For robotic spacecraft, it is usually a liquid propellant tank or battery. For human spacecraft, there are also pressurized living quarters and life-support systems. One of the design considerations of such spacecraft is the possible damage that might occur in the event of an on-orbit impact by a micrometeoroid or orbital debris (MMOD) particle. While considerable energy and effort has been expended in the study of the response of nonpressurized spacecraft components to these kinds of impacts, relatively few studies have been conducted on the pressurized elements of such spacecraft. In addition, the design criteria currently used by the National Aeronautics and Space Administration (NASA) for pressurized tanks operating in the MMOD environment have not been tested or scrutinized since they were first proposed nearly 45 years ago. This paper reviews current NASA design criteria for pressurized vessels and offers suggestions for next steps in their further development.

  7. Robotic general surgery: current practice, evidence, and perspective.

    2015-04-01

    Robotic technology commenced to be adopted for the field of general surgery in the 1990s. Since then, the da Vinci surgical system (Intuitive Surgical Inc, Sunnyvale, CA, USA) has remained by far the most commonly used system in this domain. The da Vinci surgical system is a master-slave machine that offers three-dimensional vision, articulated instruments with seven degrees of freedom, and additional software features such as motion scaling and tremor filtration. The specific design allows hand-eye alignment with intuitive control of the minimally invasive instruments. As such, robotic surgery appears technologically superior when compared with laparoscopy by overcoming some of the technical limitations that are imposed on the surgeon by the conventional approach. This article reviews the current literature and the perspective of robotic general surgery. While robotics has been applied to a wide range of general surgery procedures, its precise role in this field remains a subject of further research. Until now, only limited clinical evidence that could establish the use of robotics as the gold standard for procedures of general surgery has been created. While surgical robotics is still in its infancy with multiple novel systems currently under development and clinical trials in progress, the opportunities for this technology appear endless, and robotics should have a lasting impact to the field of general surgery.

    Full Text Available BackgroundThe e-patient revolution increasingly enables patients to self diagnose and self educate, influencing decisions affecting their health. This poses a challenge for both patients and health care professionals due to the highly variable and often poor quality information available on the internet.AimsThis study aims to measure the current internet usage in patients attending outpatient clinics, in both a public and private setting. All patients were recruited whilst consulting orthopaedic surgeons.MethodWe developed a 29 question survey which asked questions related to patient demographics, general internet usage and internet usage related to the patient’s orthopaedic condition. Patients were recruited for the public cohort during Western Health outpatient clinics and for the private cohort during private surgical consults in the waiting rooms of eight surgeons’ clinics.ResultsA total of 400 surveys were completed; 200 in both the private and public cohorts of the study. Of all surveyed participants, 79% (n = 316 had access to the internet. Of people who had access to the internet 65.2% (n = 206 used the internet to investigate their orthopaedic condition. 29.6% (n = 61 of participants asked their surgeon questions related to information they had read on the internet. Of patients that had access to the internet 36.1% (n = 114 used the internet to research their surgeon.ConclusionPatients are commonly using the internet as an information resource, in spite of the highly variable quality of this information. This highlights the need for patient information websites which reflect the current standards of clinical practice.

    Full Text Available Postoperative delirium (POD represents an acute brain dysfunction in the postsurgical period. Perioperative physicians caring for the older adults are familiar with the care of dysfunction of organs such as lungs, heart, liver, or kidney in the perioperative setting, but they are less familiar with management of brain dysfunction. As early detection and prompt treatment of inciting factors are utmost important to prevent or minimize the deleterious outcomes of delirium. The purpose of this review is to prepare perioperative physicians with a set of current clinical practice recommendations to provide optimal perioperative care of older adults, with a special focus on specific perioperative interventions that have been shown to prevent POD. On literature search in EMBASE, CINAHL, and PUBMED between January 2000 and September 2015 using search words delirium, POD, acute postoperative confusion, and brain dysfunction resulted in 9710 articles. Among them, 73 articles were chosen for review, in addition, National Institute for Health and Clinical Excellence guidelines, American Geriatric Society guidelines, hospital elderly life program-confusion assessment method training manual, New York geriatric nursing protocols, World Health Organization's International Classification of Diseases, 10th Revision classification of mental disorders, Food and Drug Administration requests boxed warnings on older class of antipsychotic drugs 2008 and delirium in Miller's text book of anesthesia were reviewed and relevant information presented in this article.

    Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy. A prospective study enrolling over a six month period (February-July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily). Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (38.0%) patients (26 cases with Interferon or Pegylated Interferon and 68 with nucleos(t)ides analogues). As many as 49.5% of subjects with chronic hepatitis did not receive antiviral treatment. The majority of chronic HBsAg carrier referring centres for evaluation were not considered suitable for antiviral treatment. Nucleos(t)ides analogues are the preferred first choice for therapy. A long-lasting period of observation may be needed to make appropriate therapeutic decisions in several cases. Copyright © 2012 European Federation of Internal Medicine. Published by Elsevier B.V.

    2015-01-01

    Background Controversy presently exists surrounding the management of patients with subacromial impingement. This study aims to highlight current UK practices in the management of these patients. Methods BESS members were invited to complete a questionnaire and responses were received from 157 consultant shoulder surgeons. Results Physiotherapy is an integral part of management for 93% of surgeons with a minimum period of 12 weeks being most popular prior to consideration of arthroscopic subacromial decompression. Subacromial steroid injection is used by 95% and 86% repeat this if the patient has failed to respond to a previous injection by the general practioner. From initial presentation, 77% felt there should be at least 3 months of conservative management before proceeding to surgery. Good but transient response to subacromial injection was considered the best predictor of good surgical outcome by 77%. The coracoacromial ligament is fully released by 78%, although there was greater variation in how aggressive surgeons were with acromioplasty. Most (59%) do not include the nontender acromioclavicular joint to any extent in routine acromioplasty. Hospital physiotherapy protocols are used by 63% for postoperative rehabilitation. Conclusions Variation exists in the management regimes offered to patients with subacromial impingement, but most employ a minimum period of 12 weeks of conservative management incorporating physiotherapy and at least 2 subacromial steriod injections.

    Studies of human reverse cholesterol transport require intravenous infusion of cholesterol tracers. Because insoluble lipids may pose risk and because it is desirable to have consistent doses of defined composition available over many months, we investigated the manufacture of cholesterol tracer under current good manufacturing practice (CGMP) conditions appropriate for phase 1 investigation. Cholesterol tracer was prepared by sterile admixture of unlabeled cholesterol or cholesterol-d7 in ethanol with 20% Intralipid(®). The resulting material was filtered through a 1.2 micron particulate filter, stored at 4°C, and tested at time 0, 1.5, 3, 6, and 9 months for sterility, pyrogenicity, autoxidation, and particle size and aggregation. The limiting factor for stability was a rise in thiobarbituric acid-reacting substances of 9.6-fold over 9 months (P manufacturing methods can be achieved in the academic setting and need to be considered for critical components of future metabolic studies.

    Gastric cancer is the second most common cause of death from cancer in Asia. Although surgery is the standard treatment for this disease, early detection and treatment is the only way to reduce mortality. This Review summarises the epidemiology of gastric cancer, and the evidence for, and current practices of, screening in Asia. Few Asian countries have implemented a national screening programme for gastric cancer; most have adopted opportunistic screening of high-risk individuals only. Although screening by endoscopy seems to be the most accurate method for detection of gastric cancer, the availability of endoscopic instruments and expertise for mass screening remains questionable--even in developed countries such as Japan. Therefore, barium studies or serum-pepsinogen testing are sometimes used as the initial screening tool in some countries, and patients with abnormal results are screened by endoscopy. Despite the strong link between infection with Helicobacter pylori and gastric cancer, more data are needed to define the role of its eradication in the prevention of gastric cancer in Asia. At present, there is a paucity of quality data from Asia to lend support for screening for gastric cancer.

    Acute calculous cholecystitis (ACC) is the most frequent complication of cholelithiasis and represents one-third of all surgical emergency hospital admissions, many aspects of the disease are still a matter of debate. Knowledge of the current evidence may allow the surgical team to develop practical bedside decision-making strategies, aiming at a less demanding procedure and lower frequency of complications. In this regard, recommendations on the diagnosis supported by specific criteria and severity scores are being implemented, to prioritize patients eligible for urgency surgery. Laparoscopic cholecystectomy is the best treatment for ACC and the procedure should ideally be performed within 72 h. Early surgery is associated with better results in comparison to delayed surgery. In addition, when to suspect associated common bile duct stones and how to treat them when found are still debated. The antimicrobial agents are indicated for high-risk patients and especially in the presence of gallbladder necrosis. The use of broad-spectrum antibiotics and in some cases with antifungal agents is related to better prognosis. Moreover, an emerging strategy of not converting to open, a difficult laparoscopic cholecystectomy and performing a subtotal cholecystectomy is recommended by adept surgical teams. Some authors support the use of percutaneous cholecystostomy as an alternative emergency treatment for acute Cholecystitis for patients with severe comorbidities. PMID:28603584

    Over the last decade, robotics has gained popularity and is increasingly employed to accomplish several abdominal surgical procedures. Nevertheless, pancreatectomies are regarded as demanding procedures for which the application of minimally-invasive surgery is still limited and its effectiveness has not been conclusively established. We aimed to investigate the current role of robot-assisted surgery to perform distal pancreatectomy. A systematic review of the English-language literature was conducted for articles dealing with robotic-assisted distal pancreatectomies. All relevant papers were evaluated on surgical and oncological outcomes. A total of 10 articles reporting on robotic distal pancreatectomies were finally considered in the analysis, including 259 patients. Mean operative time was 271 minutes (range 181-398); mean blood loss was 210 mL (range 104-361), in 11.6% of cases conversion to laparotomy occurred, spleen preservation was accomplished in 51.4% of procedures, mean time of postoperative hospital stay was 7 days. Overall, postoperative mortality and morbidity were 0% and 23.4% respectively, the mean number of lymph nodes harvested was 12.7. In all included series, no case of R1 resection was reported. Despite its relatively recent introduction in clinical practice, robotic-assisted surgery has been widely employed to perform distal pancreatectomy worldwide and it should be considered a safe and effective procedure. Both surgical and pathologic data support its application in the management of pancreatic lesions of the body and tail.

    As a result of the CD28 superagonist biotherapeutic monoclonal antibody (TGN 1412) "cytokine storm" incident, cytokine release assays (CRA) have become hazard identification and prospective risk assessment tools for screening novel biotherapeutics directed against targets having a potential risk for eliciting adverse pro-inflammatory clinical infusion reactions. Different laboratories may have different strategies, assay formats, and approaches to the reporting, interpretation, and use of data for either decision making or risk assessment. Additionally, many independent contract research organizations (CROs), academic and government laboratories are involved in some aspect of CRA work. As a result, while some pharmaceutical companies are providing CRA data as part of the regulatory submissions when necessary, technical and regulatory practices are still evolving to provide data predictive of cytokine release in humans and that are relevant to safety. This manuscript provides an overview of different approaches employed by the pharmaceutical industry and CROs, for the use and application of CRA based upon a survey and post survey follow up conducted by ILSI-Health and Environmental Sciences Institute (HESI) Immunotoxicology Committee CRA Working Group. Also discussed is ongoing research in the academic sector, the regulatory environment, current limitations of the assays, and future directions and recommendations for cytokine release assays.

    1991-05-15

    To determine current practices in the management of ocular toxoplasmosis, 72 of 85 uveitis specialists (85%) in the American Uveitis Society completed a detailed questionnaire. Questions involved the indications for beginning treatment, choice of antiparasitic/antimicrobial agents, and experience with treatment of ocular toxoplasmosis in special situations including pregnancy, neonatal infections, and immunocompromised patients. Most of the respondents treat patients whose visual acuity had decreased to worse than 20/200, lesions located in the peripapillary, perifoveal, or maculopapillary bundle regions, and lesions associated with severe vitreous inflammation. Most would not treat patients who retained visual acuity of 20/20, lesions located in the far peripheral retina, or lesions associated with only trace to mild vitreous inflammation. Treatment of other combinations of factors remains controversial. Eight different antimicrobial drugs are used in various combinations for lesions threatening the macula or optic nerve head. Systemic corticosteroids are used by 59 of 62 respondents (95%) as part of their initial treatment regimen. The most commonly used regimens are pyrimethamine/sulfadiazine/corticosteroids (20 of 62 [32%]) and pyrimethamine/sulfadiazine/clindamycin/corticosteroids (17 of 62 [27%]). Adjunctive therapies (photocoagulation, cryotherapy, or vitrectomy) have been used by 20 of 60 respondents (33%). Most alter treatment during pregnancy, in newborn patients, and in patients with the acquired immunodeficiency syndrome.

    UD evaluation principles are difficult to implement in product design. This study proposes a methodology for implementing UD in the design process through user participation. The original UD principles and user experience are used to develop the evaluation items. Difference of product types was considered. Factor analysis and Quantification theory type I were used to eliminate considered inappropriate evaluation items and to examine the relationship between evaluation items and product design factors. Product design specifications were established for verification. The results showed that converting user evaluation into crucial design verification factors by the generalized evaluation scale based on product attributes as well as the design factors applications in product design can improve users' UD evaluation.

    Implementation of Building Information Modelling (BIM) was expected to bring improvement in current practices of Malaysian construction industry. In the design phase, there is a lack of a ready pool of skilled workers who are able to develop BIM strategic plan and effectively utilise it. These create boundaries for BIM nature in Malaysian construction industry specifically in the design phase to achieve its best practices. Therefore, the objectives of this research are to investigate the current practices of BIM implementation in the design phase as well as the best practices factors of BIM implementation in the design phase. The qualitative research approach is carried out through semi-structured interviews with the designers of different organisations which adopt BIM in the design phase. Data collection is analysed by executing content analysis method. From the findings, the best practices factors of BIM implementation in design phase such as the incentive for BIM training, formal approach to monitoring automated Level of Detailing (LOD), run a virtual meeting and improve Industry Foundation Class (IFC). Thus, best practices factors which lead to practices improvements in the design phase of project development which subsequently improves the implementation of BIM in the design phase of Malaysian construction industry.

    Niacin, a potent high-density lipoprotein cholesterol-raising drug, seems an attractive approach to reduce cardiac events in patients with or at risk of atherosclerotic cardiovascular disease. However, previous evidence for niacin has been challenged recently by negative outcomes in 2 large, randomized, controlled trials comparing niacin to placebo with background statin therapy. We studied the currently available evidence for the role of niacin treatment for reducing the risk of cardiovascular events in current practice. A systematic review of randomized controlled trials in the MEDLINE, EMBASE, CINAHL, and Cochrane databases comparing niacin alone or combined with statin therapy was performed. We extracted trial level data, including basic characteristics and number of patients enrolled, duration of follow up, occurrence of adverse events, and cardiovascular-related outcomes. Random effects meta-analysis was conducted to estimate the risk ratio (RR) for individual trial endpoints. Thirteen trials (N = 35,206) were selected for final analysis. The mean follow-up duration was 32.8 months. Overall, niacin led to significant increases in serum high-density lipoprotein cholesterol levels from baseline trial enrolment by 21.4%, 9.31 (95% confidence interval [CI] 5.11-13.51) mg/dL. However, we did not observe any differences in all-cause mortality rates (RR 0.99; 95% CI 0.88-1.12) between niacin and control arms. Further, niacin treatment was associated with a trend toward lower risk of cardiovascular mortality (RR 0.91; 95% CI 0.81-1.02), coronary death (RR 0.93; 95% CI 0.78-1.10), nonfatal myocardial infarction (RR 0.85; 95% CI 0.73-1.0), revascularization (coronary and noncoronary) (RR 0.83; 95% CI 0.65-1.06), and stroke (RR 0.89; 95% CI 0.72-1.10), compared with control. Niacin therapy does not lead to significant reductions in total or cause-specific mortality or recurrent cardiovascular events among persons with or at risk of atherosclerotic cardiovascular

    clean water future. More than a decade has passed since our first statewide WOW conversation and the report that captured recommendations from its participants: Waters of Wisconsin: The Future of Our Aquatic Ecosystems and Resources. Drawing from a diverse and growing set of stakeholders from across the state, the Wisconsin Academy initiated a new conversation in 2012 (known as WOW II) to assess progress in regard to our 2003 recommendations. We also sought to review the status of waters in Wisconsin today. The result of this renewed conversation is Shifting Currents: Progress, Setbacks, and Shifts in Policy and Practice. The new report assesses progress in brief, and explores in greater depth the continuing and emerging challenges to water quality, supply, and aquatic ecosystems in Wisconsin.In this report, we first review the context and frameworks for public decision-making about water and then examine some of the root causes—or “drivers”—and ecological stressors that underlie many of the symptoms we see in the form of pollution or ecosystem degradation in Wisconsin. This is followed by a summary of current water issues, many of which had been identified in the 2003 report and remain relevant today. We examine progress since 2003 but also setbacks, and discuss issues that we are likely to continue to face in the coming decades, including controlling agricultural runoff, mitigating climate change and grappling with its effects on the state’s waters, protecting groundwater from bacterial contamination and other pollutants, and preventing groundwater depletion. We also attempt to anticipate issues on the horizon. We offer a deeper look at some particular challenges, such as phosphorus pollution and groundwater contamination. We then consider the current decision-making framework and how it is shaping our capacity to respond to water challenges in Wisconsin. Finally, we offer recommendations and identify opportunities to safeguard Wisconsin’s waters in the

    The Electrostatic Discharge phenomenon is a great threat to all electronic devices and ICs. An electric charge passing rapidly from a charged body to another can seriously harm the last one. However, there is a lack in a linear mathematical approach which will make it possible to design a circuit capable of producing such a sophisticated current waveform. The commonly accepted Electrostatic Discharge current waveform is the one set by the IEC 61000-4-2. However, the over-simplified circuit included in the same standard is incapable of producing such a waveform. Treating the Electrostatic Discharge current waveform of the IEC 61000-4-2 as reference, an approximation method, based on Prony’s method, is developed and applied in order to obtain a linear system’s response.

    The versatility, speed, and reduced costs with which web surveys can be conducted with clinicians are often offset by low response rates. Drawing on best practices and general recommendations in the literature, we provide an evidence-based overview of methods for conducting online surveys with providers. We highlight important advantages and disadvantages of conducting provider surveys online and include a review of differences in response rates between web and mail surveys of clinicians. When administered online, design-based features affect rates of survey participation and data quality. We examine features likely to have an impact including sample frames, incentives, contacts (type, timing, and content), mixed-mode approaches, and questionnaire length. We make several recommendations regarding optimal web-based designs, but more empirical research is needed, particularly with regard to identifying which combinations of incentive and contact approaches yield the highest response rates and are the most cost-effective.

  2. Some current issues in the design of HIV noninferiority trials.

    2014-08-24

    Since the introduction of protease inhibitors and their combination with two nucleoside reverse transcriptase inhibitors in tri-therapy, there has been a continuous improvement in the efficacy of antiretroviral treatments. Such combinations have been rendered even more effective by the introduction of non-nucleoside reverse transcriptase inhibitors and, more recently, integrase inhibitors. This progress has led to a move away from superiority designs towards noninferiority designs for randomized clinical trials for HIV. Noninferiority trials aim to demonstrate that a new regimen is no worse than the current standard. The methodological issues associated with such designs have been discussed, but recent HIV trials provide us with an opportunity to consider the choice of hypotheses. Recent HIV trials have been overpowered, due to the assumption of lower success rates than observed and the enrollment of a large number of patients. The use of stratified statistical methods for primary endpoint analysis, with sample size calculated by classical methods (without stratification), also increases the statistical power. Some HIV trials have a statistical power close to 99%. Surprisingly, the results of some previous studies or phase II trials are not taken into account when designing the corresponding phase III trials. We discuss alternative hypotheses and designs.

    Following the design, fabrication and test of a series of trial leads, designs of the three types of current leads required for ITER have been developed, and targeted trials of specific features are in progress on the way to fabrication and testing of prototype units. These leads are of the hybrid type with a cold section based on the use of high temperature superconductor (HTS) and a resistive section cooled by forced flow of helium gas, optimized for operation at 68 kA, 55 kA and 10 kA. The leads incorporate relevant features of the large series of current leads developed and constructed for the CERN-LHC, relevant features of the trial leads built for ITER, and additional features required to fully satisfy the exigent constraints of ITER with regard to cooling, insulation, and interfaces to feeder and powering systems. In this report a description of the design of the leads is presented, together with plans for the preparation of prototype manufacture and testing at ASIPP.

The eviction was in part motivated by a Dutch-Indonesian alliance, to construct a 40 billion USD sea wall and reclaimed islands to prevent the city from slowly sinking. In this text we start by asking, how are people living in Pasar Ikan responding to and enacting their own futures through repair? What does repair in a landscape of complete disrepair look like? And how is history both erased and enacted in this process? We then move to West Kalimantan where a DIY drone collective makes aerial drone technology and trains groups to map land that they say is vulnerable to incursions by resource developers. We ask, how is the forest located, recognized and constituted by these and other cartographic practices? Whose time and in what time are forest boundaries set and reset by mapping techniques in West Kalimantan? How do these cartographies become artifacts that travel and influence how history is thought and practiced?

The contribution of the paper is an analysis of qualities that we find a material programming practice would and should support: designs grounded in material properties and experiences, embodied programming practice, real-time on......-site explorations, and finally a reasonable level of complexity in couplings between input and output. We propose material programming knowing that the technology and materials are not entirely ready to support this practice yet, however, we are certain they will be and that the interaction design community...

    In 2002 and 2007, the American College of Critical Care Medicine (ACCCM) provided clinical guidelines for hemodynamic support of pediatric and neonatal patients in septic shock. In 2008 and 2013, the Surviving Sepsis Campaign (SSC) Guidelines Committee offered up-to-date clinical guidelines for the management of severe sepsis and septic shock in adults and in pediatric patients. The aim of this study was to assess the standard of care of neonates with severe sepsis and septic shock in German neonatal intensive care units (NICUs) with regard to variability in management and guideline conformity. 199 pediatric clinics in Germany were asked to describe their management of septic neonates in a telephone survey. The questionnaire that was used for the preliminary survey was designed based on the ACCCM and SSC clinical guidelines. A total of 90 (45%) surveys were completed and analyzed. Among all hospitals, the guidelines most commonly included in current practice patterns were obtaining cultures before administering antibiotics (100%), determining capillary refill time (99%), and using crystalloids for initial fluid therapy (97%). The guidelines least commonly included in current practice were determination of ammoniac to rule out inborn errors of metabolism (51%) and the use of dopamine as the first choice of hemodynamic support (48%). The management of sepsis, severe sepsis, and septic shock in neonates is not always guideline consistent, but quite a number of ACCCM and SSC guidelines were included in the current practice pattern. © Georg Thieme Verlag KG Stuttgart · New York.

  2. Design of Supervision Systems: Theory and Practice

    Science.gov (United States)

    Bouamama, Belkacem Ould

    2008-06-01

    The term "supervision" means a set of tools and methods used to operate an industrial process in normal situation as well as in the presence of failures or undesired disturbances. The activities concerned with the supervision are the Fault Detection and Isolation (FDI) in the diagnosis level, and the Fault Tolerant Control (FTC) through necessary reconfiguration, whenever possible, in the fault accommodation level. The final goal of a supervision platform is to provide the operator a set of tools that helps to safely run the process and to take appropriate decision in the presence of faults. Different approaches to the design of such decision making tools have been developed in the past twenty years, depending on the kind of knowledge (structural, statistical, fuzzy, expert rules, functional, behavioural…) used to describe the plant operation. How to elaborate models for FDI design, how to develop the FDI algorithm, how to avoid false alarms, how to improve the diagnosability of the faults for alarm management design, how to continue to control the process in failure mode, what are the limits of each method,…?. Such are the main purposes concerned by the presented plenary session from an industrial and theoretical point of view.

  3. Design Facilitation as Emerging Practice: Analyzing How Designers Support Multi-stakeholder Co-creation

    Directory of Open Access Journals (Sweden)

    Manuela Aguirre

    Full Text Available Designers increasingly find themselves facilitating large-scale design events. Yet few have explored design facilitation as an emerging practice. This article examines the design facilitation practices used in two Norwegian case studies of multi-stakeholder events. We focus on the contextually designed tools designers create to help them facilitate. We then explore some critical dimensions of design facilitation. When used as visual overlays, facilitators’ explicit knowledge of these dimensions can improve their capacity to analyze, evaluate, and plan how to design and use contextual tools during design events. By plotting how designers use facilitation tools sequentially during events, we render the flow of design facilitation practice visible and accessible. We suggest that an explicit awareness of these dimensions and flows can enable designers to build more inclusive and inspiring tools, orchestrate the flow of long-term participatory processes more deliberately, and better equip participants to work with complex systemic change.

    2017-10-01

    Hypnosis is very fashionable as an entertainment through TV shows searching for new sensational experiences. What about its practice in the medical world? The aim of this article is to answer to this question. Therefore, we contacted every French University Hospital of each region to find out if hypnosis was practiced for the care of pain (hypnoanalgesia), for chirurgical procedures (hypnosedation) and in adult psychiatry care units (hypnotherapy). For this last practice, we also questioned the type of indications. All 30 of the French University Hospitals had replied by November 2015. Hypnoanalgesia is practiced by all and two-thirds offer hypnosedation. Hypnotherapy is practiced by 40 % of the University Hospitals, 91,7 % for anxiety disorders, 66,7 % for psychotraumatic care and 25 % for mood disorders. Therefore, hypnosis seems to have found its place in the care of pain and as an anesthetic to replace standard procedures. However, the use of hypnotherapy in psychiatry is less frequent, indications for its use being variable and not very consensual. Copyright © 2016 L’Encéphale, Paris. Published by Elsevier Masson SAS.

    Hedgepeth, J. M.; Mikulas, M. M., Jr.; Macneal, R. H.

    1978-01-01

    The practical design of low-cost space structures involves the use of approaches that reduce the cost of the design and development effort itself. Such approaches include: (1) design with criteria arrived at rationally; (2) design for simplicity, repeatability, and modularity; (3) assembly without adjustments; (4) design for testability on the ground; (5) the attainment of structural efficiency by configuration and material choice rather than by squeezing down on the design margins; and (6) prefabrication and preassembly before launch. Attention is given to truss platform designs, and the Seasat Extendible Support Structure is discussed as a particular example.

  10. The role of community pharmacy-based vaccination in the USA: current practice and future directions

    2015-07-01

    Full Text Available Albert T Bach, Jeffery A Goad School of Pharmacy, Chapman University, Irvine, California, USA Abstract: Community pharmacy-based provision of immunizations in the USA has become commonplace in the last few decades, with success in increasing rates of immunizations. Community pharmacy-based vaccination services are provided by pharmacists educated in the practice of immunization delivery and provide a convenient and accessible option for receiving immunizations. The pharmacist's role in immunization practice has been described as serving in the roles of educator, facilitator, and immunizer. With a majority of pharmacist-provided vaccinations occurring in the community pharmacy setting, there are many examples of community pharmacists serving in these immunization roles with successful outcomes. Different community pharmacies employ a number of different models and workflow practices that usually consist of a year-round in-house service staffed by their own immunizing pharmacist. Challenges that currently exist in this setting are variability in scopes of immunization practice for pharmacists across states, inconsistent reimbursement mechanisms, and barriers in technology. Many of these challenges can be alleviated by continual education; working with legislators, state boards of pharmacy, stakeholders, and payers to standardize laws; and reimbursement design. Other challenges that may need to be addressed are improvements in communication and continuity of care between community pharmacists and the patient centered medical home.

    2017-04-01

    The inspection of the hollow axle inner surfaces is a key process to guarantee the safety of high-speed trains. A novel flexible arrayed eddy current sensor was developed to improve the reliability of the non-destructive testing of the hollow axle inner surfaces, whose main innovative aspect was the new design of excitation/sensing traces to achieve a differential and arrayed configuration. Only two independent excitation traces were used in the sensor to induce eddy currents, which can be detected by 16 differential sensing elements. The lift-off effects and the influence of the excitation frequency and geometrical parameters of the proposed sensor was investigated and presented in this paper. Finite element models were built to analyze the effects of each parameter on the sensor response amplitude. Experimental validations were conducted using a representative set of sensors. Results from experiments and simulations were consistent with each other, which showed that the sensor design can substantially suppress the lift-off effects and modifications of the studied parameters can substantially improve the sensor performance.

    Calhoun, Judith G; Banaszak-Holl, Jane; Hearld, Larry R

    2006-01-01

    Marketing is widely recognized as an essential business function across all industries, including healthcare. While many long-term care facilities adopted basic healthcare marketing practices and hired marketing staff by the early 1990s, a paucity of research on nursing home marketing exists in the literature. This study examines the extent to which nursing homes have developed more formulated marketing and related communication and promotional strategies as market competition has increased in this sector during the past two decades. In addition, we explored managers' perceptions of their control over marketing decision making, the impact of competition on the use of marketing practices, and areas for enhanced competitive positioning. Administrators from 230 nursing homes in 18 Southeastern Michigan counties were surveyed regarding (1) the adoption level of approximately 40 literature-based, best-practice marketing strategies; (2) the types of staff involved with the marketing function; and (3) their perception of their level of control over marketing functions and of local competition. Results from 101 (44 percent) survey participants revealed that although respondents viewed their markets as highly competitive, their marketing practices remained focused on traditional and relatively constrained practices. In relation to the importance of customer relationship management, the majority of the administrators reported intensive efforts being focused on residents and their families, referrers, and staff, with minimal efforts being extended to insurers and other types of payers. A significant positive relation was found between the intensity of marketing initiatives and the size of the facility (number of beds), whereas significant negative correlations were revealed in relation to occupancy and the perceived level of control over the function.

    Freihoefer, Kara; Zborowsky, Terri

    2017-04-01

    The purpose of this article is to justify the need for evidence-based design (EBD) in a research-based architecture and design practice. This article examines the current state of practice-based research (PBR), supports the need for EBD, illustrates PBR methods that can be applied to design work, and explores how findings can be used as a decision-making tool during design and as a validation tool during postoccupancy. As a result, design professions' body of knowledge will advance and practitioners will be better informed to protect the health, safety, and welfare of the society. Furthermore, characteristics of Friedman's progressive research program are used as a framework to examine the current state of PBR in design practice. A modified EBD approach is proposed and showcased with a case study of a renovated inpatient unit. The modified approach demonstrates how a highly integrated project team, especially the role of design practitioners, contributed to the success of utilizing baseline findings and evidence in decision-making throughout the design process. Lastly, recommendations and resources for learning research concepts are provided for practitioners. It is the role of practitioners to pave the way for the next generation of design professionals, as the request and expectation for research become more prevalent in design practice.

    2016-01-01

    Increasing emphasis on maintaining a healthy lifestyle has led many individuals to seek advice on exercise from personal trainers. There are few studies to date that evaluate personal trainer education, practice trends, and injuries they have seen while training clients. A survey was distributed to personal trainers using Survey Monkey® (Palo Alto, CA, USA) with 605 personal trainers accessing the survey. An exercise related bachelor’s degree was held by 64.2% of survey participants and a certification in personal training by 89.0%. The most common personal trainer certifications were from American College of Sports Medicine (59.2%) and National Strength and Conditioning Association (28.9%). Only 2.9% of all personal trainers surveyed had no exercise-related bachelor’s degree and no personal trainer certification. The most common injuries seen by personal trainers during sessions were lumbar muscle strain (10.7%), rotator cuff tear/tendonitis (8.9%), shin splints (8.1%), ankle sprain (7.5%), and cervical muscle strain (7.4%). There is variability in the practices between different personal trainers when analyzing differences in collegiate education, personal trainer certifications, and strength and conditioning certifications. The clinical implication of the differences in practices is unknown as to the impact on injuries or exercise prescription effectiveness. PMID:27761219

    2015-07-01

    Full Text Available The authors of this qualitative study set out to investigate self-assessment practices within the library profession. The researchers conducted semi-structured interviews with a purposeful sample of nine librarians coming from a range of library settings and possessing a diversity of library experience. Interviews were then transcribed and coded in NVIVO to identify emergent themes. This paper details some of the results of that study, highlighting motivations, limitations, and strategies with regard to self-assessment. The findings present a summary of a range of approaches to the practice of assessment as reported by the interviewees. One area of possible growth for our profession, as highlighted by the findings, is in the development of peer networks as a support for the individual practice of self-assessment. While the results of this small case study cannot be generalized, the authors hope these preliminary findings can open up the conversation around self-assessment both for individual librarians and for those librarians and managers working to shape their workplace culture.

    2014-04-01

    This article evaluates current radiofrequency ablation systems using axiomatic design theory. Due to its minimally invasive procedure, short-time hospital stay, low cost, and tumour metastasis treatment, the radiofrequency ablation technique has been playing an important role in tumour treatment in recent decades. Although the radiofrequency ablation technique has many advantages, some issues still need to be addressed. Among these issues, the two most important are as follows: (1) the size of tumours to be removed (has to be larger than 3 cm in diameter) and (2) cleanness of the removal. Many device solutions have been proposed to address the two issues. However, there is a lack of knowledge regarding the systematic evaluation of these solutions. This article evaluates these systems in terms of their solution principles (or simply called conceptual design in general product design theory) using a design theory called axiomatic design theory. In addition, with the axiomatic design theory, a better conceptual design in terms of its feasibility to cope with incomplete target tissue necrosis from the large size of tumours has been found. The detailed analysis and simulation of the new conceptual design are conducted using finite element approach. The results in this article are proved by the information of animal experiments and clinical practices obtained from the literature. This study thus contributes to the current knowledge to further developments in radiofrequency ablation systems and procedure guidelines for physicians to perform the radiofrequency ablation operation more effectively.

    Optical design, together with applied optics, forms a complete system from basic theory to application theory, and it plays a very important role in professional education. In order to improve senior undergraduates' understanding of optical design, this course is divided into three parts: theoretical knowledge, software design and product processing. Through learning theoretical knowledge, students can master the aberration theory and the design principles of typical optical system. By using ZEMAX(an imaging design software), TRACEPRO(a lighting optical design software), SOLIDWORKS or PROE( mechanical design software), student can establish a complete model of optical system. Student can use carving machine located in lab or cooperative units to process the model. Through the above three parts, student can learn necessary practical knowledge and get improved in their learning and analysis abilities, thus they can also get enough practice to prompt their creative abilities, then they could gradually change from scientific theory learners to an Optics Engineers.

  1. Current State of Agile User-Centered Design: A Survey

    Science.gov (United States)

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    Agile software development methods are quite popular nowadays and are being adopted at an increasing rate in the industry every year. However, these methods are still lacking usability awareness in their development lifecycle, and the integration of usability/User-Centered Design (UCD) into agile methods is not adequately addressed. This paper presents the preliminary results of a recently conducted online survey regarding the current state of the integration of agile methods and usability/UCD. A world wide response of 92 practitioners was received. The results show that the majority of practitioners perceive that the integration of agile methods with usability/UCD has added value to their adopted processes and to their teams; has resulted in the improvement of usability and quality of the product developed; and has increased the satisfaction of the end-users of the product developed. The top most used HCI techniques are low-fidelity prototyping, conceptual designs, observational studies of users, usability expert evaluations, field studies, personas, rapid iterative testing, and laboratory usability testing.

    Present a methodology to promote good practices in designing small-scale, practice-based studies. We propose the following methods to assist clinicians and other practice-based researchers in designing and conducting good quality, small-scale studies in a clinical setting. Research projects applied to a limited, practice-based study may require modification to increase the consistency of patient research. Although common requests to collaborative methodologists mirror methods for experimental design, clinic-based studies may face different limitations. Each participant enrolled consumes resources, including time, and personnel. If practice-based studies have a different goal, to learn about the health outcomes of patients in a medical practice with limited intent for generalization, should the same methods be used? When limitations are clearly stated and the findings are described within the study context, these limitations may not be so severe to discourage the research. We propose a systematic method to conduct practice-based research intended for small-scale study use. Relying heavily on existing research from similar areas, the incorporation of data from the practice, and the a priori defined timelines and resources, we set forth some guiding principles to assist clinic-based investigators. Individualized focus and small-scale studies are growing in use and acceptance especially given the focus on personalized health.

  10. Emergency nurses' current practices and understanding of family presence during CPR.

    LENUS (Irish Health Repository)

    Madden, Eilis

    2012-02-03

    PURPOSE: To examine emergency nurses\\' current practices and understanding of family presence during CPR in the emergency department, Cork University Hospital, Republic of Ireland. METHOD: A quantitative descriptive design was used in the study. A questionnaire developed by ENA was distributed to emergency nurses working in a level I trauma emergency department at Cork University Hospital. The total sample number was 90, including all emergency nurses with at least 6 months\\' emergency nursing experience. RESULTS: Emergency nurses often took families to the bedside during resuscitation efforts (58.9%) or would do so if the opportunity arose (17.8%). A high percentage (74.4%) of respondents would prefer a written policy allowing the option of family presence during CPR. The most significant barrier to family witnessed resuscitation (FWR) was conflicts occurring within the emergency team. The most significant facilitator to FWR was a greater understanding of health care professionals on the benefits of FWR to patients and families, indicating the need for educational development. CONCLUSION: The findings of the study and previously published studies indicate the need for development of written polices and guidelines on the practice to meet the needs of patients, families, and staff by providing consistent, safe, and caring practices for all involved in the resuscitation process. Recommendations of the study include the development of a written policy and an educational programme on the safe implementation and practices of FWR.

  11. A critique of current practice: ten foundational guidelines for autoethnographers.

    Tolich, Martin

    2010-12-01

    Any research is potentially compromised when researchers address ethical issues retrospectively rather than by anticipating these issues. In this regard, creative analytical practices (CAP) autoethnography has endemic problems. In Part 1 of this article, I detail a case study of an autoethnography in which journal reviewers insisted that an author gain retrospective informed consent from the 23 persons documented in an autoethnography. Yet the journal reviewers' insistence failed to go one step further-acknowledging that a conflict of interest develops when gaining consent retrospectively. In Part 2, I contrast three leading autoethnographers' justifications for not gaining informed consent with the Position Statement on Qualitative Research developed by successive Congresses of Qualitative Inquiry. In Part 3, I identify resources available for autoethnographers, including ethical issues present when researchers use autoethnography to heal themselves, violating the internal confidentiality of relational others. In Part 4, I question if autoethnography is research and, like journalism, exempt from formal ethics review. Throughout the article, 10 foundational ethical considerations for autoethnographers are developed, taking autoethnographers beyond procedural ethics and providing tools for their ethics in practice.

  12. Premedication for neonatal intubation: Current practice in Saudi Arabia

    2012-01-01

    Full Text Available Background: Despite strong evidence of the benefits of rapid sequence intubation in neonates, it is still infrequently utilized in neonatal intensive care units (NICU, contributing to avoidable pain and secondary procedure-related physiological disturbances. Objectives: The primary objective of this cross-sectional survey was to assess the practice of premedication and regimens commonly used before elective endotracheal intubation in NICUs in Saudi Arabia. The secondary aim was to explore neonatal physicians′ attitudes regarding this intervention in institutions across Saudi Arabia. Methods: A web-based, structured questionnaire was distributed by the Department of Pediatrics, Umm Al Qura University, Mecca, to neonatal physicians and consultants of 10 NICUs across the country by E-mail. Responses were tabulated and descriptive statistics were conducted on the variables extracted. Results: 85% responded to the survey. Although 70% believed it was essential to routinely use premedication for all elective intubations, only 41% implemented this strategy. 60% cited fear of potential side effects for avoiding premedication and 40% indicated that the procedure could be executed more rapidly without drug therapy. Treatment regimens varied widely among respondents. Conclusion: Rates of premedication use prior to non-emergent neonatal intubation are suboptimal. Flawed information and lack of unified unit policies hampered effective implementation. Evidence-based guidelines may influence country-wide adoption of this practice.

    2013-04-01

    At the beginning of the 20th Century, cervical cancer was the leading cause of death from cancer in women. A marked decline in cervical cancer has been observed since the 1960s, in parallel with the introduction of the Papanicolau (Pap) test as a cytological screening method. Today, Pap smear screening is still the most widely used tool for cervical cancer prevention. Testing for human papillomavirus (HPV) in cervical specimens or a combination of Pap and HPV testing are also now available. In this article we compare current guidelines for cervical cancer screening in Switzerland with those in other European countries. In view of the opportunities offered by HPV testing and, since 2008, HPV vaccination, current guidelines for cervical cancer screening should be updated. Both the choice of screening tests and general organization of cervical cancer screening should be reviewed.

    When a conductive material is subjected to time-varying magnetic fluxes, eddy (Foucault) currents are generated in it and magnetic field of opposite polarity as the applied one arises. Due to the internal resistance of the conductive material, the eddy currents will be dissipated into heat (Joule heating). Conventional domestic water heaters utilize gas burners or electric resistance heating elements to heat the water in the tank and substantial part of the energy to use for it is wasted. In this paper the origin of electromagnetic induction heat generated by wind turbine in special heat exchange camera connected to water boiler is discussed and material evaluation performed using mathematical modelling (comparing the 2D finite element model with analytical and numerical calculation results).

  16. Parallel programming practical aspects, models and current limitations

    CERN Document Server

    Tarkov, Mikhail S

    2014-01-01

    Parallel programming is designed for the use of parallel computer systems for solving time-consuming problems that cannot be solved on a sequential computer in a reasonable time. These problems can be divided into two classes: 1. Processing large data arrays (including processing images and signals in real time)2. Simulation of complex physical processes and chemical reactions For each of these classes, prospective methods are designed for solving problems. For data processing, one of the most promising technologies is the use of artificial neural networks. Particles-in-cell method and cellular automata are very useful for simulation. Problems of scalability of parallel algorithms and the transfer of existing parallel programs to future parallel computers are very acute now. An important task is to optimize the use of the equipment (including the CPU cache) of parallel computers. Along with parallelizing information processing, it is essential to ensure the processing reliability by the relevant organization ...

  17. Comparison of current and past surgical smoke control practices.

    2012-03-01

    In 2010, we teamed with AORN to repeat a simple web-based survey on surgical smoke control practices first conducted in 2007. This survey of AORN members assessed the level of compliance with established surgical smoke control measures (ie, use of wall suction with an in-line particulate filter, use of a smoke evacuator, use of an N95 or other National Institute for Occupational Safety and Health-approved respirator) in various medical specialties and facilities throughout North America, as well as the extent to which compliance rates may have changed since 2007. Survey responses indicate that while the use of wall suction as a control measure has increased for nearly all procedures, progress in the adoption of other control measures has been mixed, with improvement for some procedures, no change for most procedures, and a decrease in compliance for a few procedures.

    2016-01-01

    In view of the MENA increasing participation in multinational trials and the increasing number of national/regional trials, this article explores potential areas of pharmacovigilance, requiring reform and provides recommendations for building a robust safety reporting system. Regulatory silence on expedited reporting requirements creates confusion for local sites that are part of multinational trials. Not allowing waiver for serious adverse events that are protocol specified or are study endpoints, along with lack of emphasis on causality as reporting criteria, adds substantial burden of uninformative cases for regulatory review. Despite global focus on Development Safety Update Report, local regulators are not yet insistent on real-time update of a drug's cumulative safety profile. Issues like reporting requirements for generic trials, pregnancy reporting and lenient timeline for death/life-threatening events need attention. Finally, the need to formulate an all-encompassing local pharmacovigilance guideline, in sync with global practice cannot be overemphasized.

    2013-06-01

    Feedback is one of the most powerful tools, which teachers can use to enhance student learning. It appears difficult for teachers to give qualitatively good feedback, especially during active learning. In this context, teachers should provide facilitative feedback that is focused on the development of meta-cognition and social learning. The purpose of the present study is to contribute to the existing knowledge about feedback and to give directions to improve teacher feedback in the context of active learning. The participants comprised 32 teachers who practiced active learning in the domain of environmental studies in the sixth, seventh, or eighth grade of 13 Dutch primary schools. A total of 1,465 teacher-student interactions were examined. Video observations were made of active learning lessons in the domain of environmental studies. A category system was developed based on the literature and empirical data. Teacher-student interactions were assessed using this system. Results. About half of the teacher-student interactions contained feedback. This feedback was usually focused on the tasks that were being performed by the students and on the ways in which these tasks were processed. Only 5% of the feedback was explicitly related to a learning goal. In their feedback, the teachers were directing (rather than facilitating) the learning processes. During active learning, feedback on meta-cognition and social learning is important. Feedback should be explicitly related to learning goals. In practice, these kinds of feedback appear to be scarce. Therefore, giving feedback during active learning seems to be an important topic for teachers' professional development. © 2012 The British Psychological Society.

    To determine the degree of consensus among clinicians on the clinical use of genetic testing in amyotrophic lateral sclerosis (ALS) and the factors that determine decision-making. ALS researchers worldwide were invited to participate in a detailed online survey to determine their attitudes and practices relating to genetic testing. Responses from 167 clinicians from 21 different countries were analyzed. The majority of respondents (73.3%) do not consider that there is a consensus definition of familial ALS (FALS). Fifty-seven percent consider a family history of frontotemporal dementia and 48.5% the presence of a known ALS genetic mutation as sufficient for a diagnosis of FALS. Most respondents (90.2%) offer genetic testing to patients they define as having FALS and 49.4% to patients with sporadic ALS. Four main genes (SOD1, C9orf72, TARDBP, and FUS) are commonly tested. A total of 55.2% of respondents would seek genetic testing if they had personally received a diagnosis of ALS. Forty-two percent never offer presymptomatic testing to family members of patients with FALS. Responses varied between ALS specialists and nonspecialists and based on the number of new patients seen per year. There is a lack of consensus among clinicians as to the definition of FALS. Substantial variation exists in attitude and practices related to genetic testing of patients and presymptomatic testing of their relatives across geographic regions and between experienced specialists in ALS and nonspecialists.

    2018-01-01

    Full Text Available Introduction: Rural and low-resource areas have diminished capacity to care for neurosurgical patients due to lack of infrastructure, healthcare investment, and training programs. This review summarizes the range of rural neurosurgical procedures, novel mechanisms for delivering care, rapid training programs, and outcome differences across international rural neurosurgical practice. Methods: A comprehensive literature search was performed for English language manuscripts with keywords “rural” and “neurosurgery” using the National Library of Medicine PubMed database (01/1971–06/2017. Twenty-four articles focusing on rural non-neurosurgical practice were included. Results: Time to care and/or surgery and shortage of trained personnel remain the strongest risk factors for mortality and poor outcome. Telemedicine consults to regional centers with neurosurgery housestaff have potential for increased timeliness of diagnosis/triage, improved time to surgery, and reductions in unnecessary transfers in remote areas. Mobile neurosurgery teams have been deployed with success in nations with large transport distances precluding initial transfers. Common neurosurgical procedures involve trauma mechanisms; accordingly, training programs for nonneurosurgery medical personnel on basic assessment and operative techniques have been successful in resource-deficient settings where neurosurgeons are unavailable. Conclusions: Protracted transport times, lack of resources/training, and difficulty retaining specialists are barriers to successful outcomes. Advances in telemedicine, mobile neurosurgery, and training programs for urgent operative techniques have been implemented efficaciously. Development of guidelines for paired partnerships between rural centers and academic hospitals, supplying surplus technology to rural areas, and rapid training of qualified local surgical personnel can create sustainable feed-forward programs for trainees and

    Requirements have remained one of the grand challenges in the design of software intensive systems. In this paper we review the main strands of requirements research over the past two decades and identify persistent and new challenges. Based on a field study that involved interviews of over 30 leading IT professionals involved in large and complex software design and implementation initiatives, we review the current state-of-the-art in the practice of design requirements management. We observe significant progress in the deployment of modeling methods, tools, risk-driven design, and user involvement. We note nine emerging themes and challenges in the requirement management arena: 1) business process focus, 2) systems transparency, 3) integration focus, 4) distributed requirements, 5) layered requirements, 6) criticality of information architectures, 7) increased deployment of COTS and software components, 8) design fluidity and 9) interdependent complexity. Several research challenges and new avenues for research are noted in the discovery, specification, and validation of requirements in light of these requirements features.

    Full Text Available The incidence of a cancer diagnosis in children and young adolescents is increasing. With better treatments, the number of young cancer survivors living through reproductive age is increasing. Fertility preservation of these men and women has become essential and needs to be discussed prior to the start of cancer treatment. Here we review the current guidelines for male oncofertility patients and highlight some of the important gonadotoxic effects of chemotherapy, radiotherapy and surgery. Options for fertility preservation are also discussed along with resources that should be made available to all patients.

    2009-06-01

    In most of the industrialized world, a childhood obesity epidemic is evident, with the numbers rising each year. To discuss the current literature in relation to childhood obesity and to provide health practitioners, especially nurses, with the fundamental knowledge that is imperative in the recognition of children who are at risk and thereby tailor appropriate interventions. Databases that were accessed for current literature included CINAHL, Science Direct and ProQuest. Keywords used in the search included obesity, childhood, health, relevant national statistics, policy and health risks. The literature was confined to the past 10 years with emphasis on the past 5 years. The 50 most pertinent papers from a variety of countries were chosen, and 35 papers that represented key areas of relevance were selected as the basis of this article. This selection of papers dictated the key areas of discussion such as the acknowledged factors in childhood obesity. Although childhood obesity may be related to specific cultural and national circumstances, universal themes emerged from the literature review. These include social factors, exercise, advertising, public policy and the importance of partnerships in policy. Any country that has a high rate or increasing rate of childhood obesity must acknowledge core factors that contribute to this serious health problem. Furthermore, public policy and community partnerships that include all health professionals have a responsibility in the prevention of childhood obesity. This can be implemented through education, research and advocacy of all nurses involved with children and families.

    2015-10-01

    Full Text Available Reflexology is basically a study of how one part of the human body relates to another part of the body. Reflexology practitioners rely on the reflexes map of the feet and hands to all the internal organs and other human body parts. They believe that by applying the appropriate pressure and massage certain spots on the feet and hands, all other body parts could be energized and rejuvenated. This review aimed to revisit the concept of reflexology and examine its effectiveness, practices, and the training for reflexology practitioners. PubMed, SCOPUS, Google Scholar, and SpringerLink databases were utilized to search the following medical subject headings or keywords: foot massage, reflexology, foot reflexotherapy, reflexological treatment, and zone therapy. The articles published for the last 10 years were included. Previous systematic reviews failed to show concrete evidence for any specific effect of reflexology in any conditions. Due to its non-invasive, non-pharmacological complementary nature, reflexology is widely accepted and anecdotal evidence of positive effect reflexology in a variety of health conditions are available. Adequate training for practitioners is necessary to ensure the consistency of service provided.

    Somatic cloning is emerging as a new biotechnology by which the opportunities arising from the advances in molecular genetics and genome analysis can be implemented in animal breeding. Significant improvements have been made in SCNT protocols in the past years which now allow to embarking on practical applications. The main areas of application of SCNT are: Reproductive cloning, therapeutic cloning and basic research. A great application potential of SCNT based cloning is the production of genetically modified (transgenic) animals. Somatic cell nuclear transfer based transgenic animal production has significant advances over the previously employed microinjection of foreign DNA into pronuclei of zygotes. This cell based transgenesis is compatible with gene targeting and allows both, the addition of a specific gene and the deletion of an endogenous gene. Efficient transgenic animal production provides numerous opportunities for agriculture and biomedicine. Regulatory agencies around the world have agreed that food derived from cloned animals and their offspring is safe and there is no scientific basis for questioning this. Commercial application of somatic cloning within the EU is via the Novel Food regulation EC No. 258/97. Somatic cloning raises novel questions regarding the ethical and moral status of animals and their welfare which has prompted a controversial discussion in Europe which has not yet been resolved. © 2012 Blackwell Verlag GmbH.

    1980-01-01

    A survey of shoe-prescribing practices for children was taken among pediatricians, orthopaedists, pediatric orthopaedists, and podiatrists. Opinions differed significantly regarding the usefulness of shoe modifications for common pediatric lower limb and foot problems. Parents' attitudes toward children's shoes were also surveyed. Pediatricians and pediatric orthopaedists tended to prescribe corrective shoes less often than did orthopaedists and podiatrists. High topped shoes are not necessary to promote normal foot development, in the opinion of 85% of those surveyed; however, high topped shoes were often recommended for infants because they slip off less easily. Preferences for Thomas heels, scaphoid pads, reverse lasts, straight lasts, wedges, torque heels, and shoe lifts for problems including flexible flat feet, metatarsus adductus, intoeing, bow legs, knock knees, and leg length inequalities were delineated among the four groups treating children's feet. The authors conclude that whereas studies show that shoe modifications are of questionable value in the problems discussed, corrective shoes are often prescribed when regular shoes would be more appropriate and economical.

  10. Overview of robotic colorectal surgery: Current and future practical developments

    2016-01-01

    Minimal access surgery has revolutionised colorectal surgery by offering reduced morbidity and mortality over open surgery, while maintaining oncological and functional outcomes with the disadvantage of additional practical challenges. Robotic surgery aids the surgeon in overcoming these challenges. Uptake of robotic assistance has been relatively slow, mainly because of the high initial and ongoing costs of equipment but also because of limited evidence of improved patient outcomes. Advances in robotic colorectal surgery will aim to widen the scope of minimal access surgery to allow larger and more complex surgery through smaller access and natural orifices and also to make the technology more economical, allowing wider dispersal and uptake of robotic technology. Advances in robotic endoscopy will yield self-advancing endoscopes and a widening role for capsule endoscopy including the development of motile and steerable capsules able to deliver localised drug therapy and insufflation as well as being recharged from an extracorporeal power source to allow great longevity. Ultimately robotic technology may advance to the point where many conventional surgical interventions are no longer required. With respect to nanotechnology, surgery may eventually become obsolete.

    Full Text Available Through the many documents regularly emitted by those dedicated to this activity, it is comparatively easy to describe factual developments in the field of open and distance education in different places in the world. However, it is much more difficult to produce judgements of value about their quality. Quality is a subjective rather than an absolute concept and may be examined from different analytical perspectives: consumers' satisfaction level, intrinsic value of scientific and technical content of learning materials, soundness of learning strategies, efficiency of organisation and procedures, adequate use of advanced technologies, reliability of student support mechanisms, etc.These parameters should be put into the context of specific objectives, nature of target populations and availability of different kinds of resources. In a specific geographic, social, economic and cultural situation a given set of solutions might be judged as adequate and deserving the qualification of "good practice," while in a different context it could be considered of rather poor quality.The selection of examples in this article is the sole responsibility of the authors: neither should the chosen cases be considered as clearly better than any other one, nor missing cases be interpreted as lack of appreciation or a negative judgement.Finally, the authors are aware of the risks of interpreting trends and trying to extrapolate them into the near future: readers should use their own judgement in accepting (or forcefully rejecting these projections.

  13. Current practice of conventional intermittent hemodialysis for acute kidney injury

    2013-01-01

    Full Text Available The use of conventional intermittent hemodialysis (IHD represents a mainstay of supportive care of patients with acute kidney injury (AKI. However, a number of fundamental questions regarding the optimal management of IHD remain unanswered after more than six decades of renal replacement therapy (RRT. This review summarizes current evidence regarding the timing of initiation of intermittent hemodialysis, the comparative outcomes (mortality and recovery of renal function, the prescription of the intensity of this therapy and discontinuation of dialysis. The way conventional IHD is performed has an impact on the outcome of sick patients with AKI. The value of regular education and training of those who provide IHD cannot be emphasized enough. However, we must be realistic in our expectations that no mode of RRT per se will substantially alter the excessive mortality of critically ill-patients with AKI.

    2014-09-01

    To provide and elucidate a comprehensible framework for the design of social research. An abundance of information exists concerning the process of designing social research. The overall message that can be gleaned is that numerable elements - both philosophical (ontological and epistemological assumptions and theoretical perspective) and practical (issue to be addressed, purpose, aims and research questions) - are influential in the process of selecting a research methodology and methods, and that these elements and their inter-relationships must be considered and explicated to ensure a coherent research design that enables well-founded and meaningful conclusions. There is a lack of guidance concerning the integration of practical and philosophical elements, hindering their consideration and explication. The author's PhD research into loneliness and cancer. This is a methodology paper. A guiding framework that incorporates all of the philosophical and practical elements influential in social research design is presented. The chronological and informative relationships between the elements are discussed. The framework presented can be used by social researchers to consider and explicate the practical and philosophical elements influential in the selection of a methodology and methods. It is hoped that the framework presented will aid social researchers with the design and the explication of the design of their research, thereby enhancing the credibility of their projects and enabling their research to establish well-founded and meaningful conclusions.

  16. Breastfeeding in Japan: historical perspectives and current attitudes and practices.

    Science.gov (United States)

    Takeuchi, M

    1992-07-01

    1. We took an extensive overview of the history of breastfeeding in Japan. Japanese people, especially farming villagers have lived with a mixed religious atmosphere including primitive religion, Shintoism and Buddhism during more than 1,000 years. In such circumstances, they had three kinds of traditional practices for inadequate breast milk production, that is, praying to God or Buddha, foods or medicines based on their experiences and wet nursing. 2. Farm villagers used to primarily feed their babies by their own breasts and some who couldn't supply adequate milk, compensated with their neighbor's milk until a century ago, because most villagers' wives had plenty of milk at that time. 3. The characteristics of farm villagers' customs were: A. irregular breastfeeding. B. a mother's keeping skinship with her baby all day. C. sleeping in the posture of KAWA's character. D. late weaning. E. EJIKO was popular nursing tool. 4. Instead of wet nursing, bottle feeding was initiated in Japan after 1867. As a result, many infants suffered from malnutrition. On the other hand, some breast-fed infants suffered from beriberi and lead encephalopathy. 5. Until 1974-75, when the recommendations of WHO and Japanese Government were announced, there had been a steady decline in breastfeeding throughout Japan. Thereafter, physicians supported breastfeeding and made efforts to diminish the disadvantages of breastfeeding in the medical field. 6. According to the report of the Japanese Government, difficulty to supply sufficient milk and obstacles against working were the most important complaints of breastfeeding mothers. I suggested strategies for solution of these complaints: A principles at puerperium in our maternity ward include effect of my low-calorie diet, and Japanese methods of massage for the breasts. B my proposals for working mothers who want to breastfeed. &. I have discussed some results of Japanese breastfeeding research. 8. Some results of our Breastfeeding Promotion

    Only a small proportion of subjects referring to hospitals for hepatitis C virus (HCV) positivity receives antiviral therapy. To evaluate the rate of antiviral treatment and the causes for no treatment in HCV-RNA positive subjects seen in hospital settings. A prospective study enrolling over a 6-month period (February-July 2009) all consecutive anti-HCV positive subjects initially referred (naïve patients) to 12 liver units in Southern Italy for HCV treatment. Out of 608 subjects evaluated, 74 (12.2%) had no detectable HCV-RNA in the serum and thus were excluded. Of the remaining 534 HCV-RNA positive subjects, 357 (66.9%) were not treated for the following reasons: 49.9% were older than 65 years of age (75% of them >70 years), 14.3% had normal liver enzymes, 13.2% had compensated/decompensated cirrhosis, 10.4% refused treatment, 9.8% had ongoing substance or alcohol abuse. Multivariate analysis showed that females (O.R. 2.27; C.I. 95% 1.05-4.90) and subjects with low educational level (O.R. 4.38; C.I. 95% 1.27-15.11) were more likely to decline therapy. The majority of patients with HCV infection does not receive antiviral treatment. The effectiveness of the current standard therapy for HCV infection is low despite its good efficacy.

    Xanthopoulou, Ioanna; Alexopoulos, Dimitrios

    2016-01-01

    Patients with ST-segment elevation myocardial infarction represent a high-risk population and an effective antiplatelet treatment adjunctive to primary percutaneous coronary intervention is of paramount importance. This topic will review the current evidence on clinical efficacy and safety of oral antiplatelet therapy in patients with an acute ST-segment elevation myocardial infarction. Unsettled issues and future perspectives for their use in these patients are also discussed. Added to aspirin, clopidogrel, prasugrel and ticagrelor represent viable options regarding oral P2Y12 inhibition, with prasugrel and ticagrelor being preferred over clopidogrel, according to results of large randomized clinical trials. Early clinical efficacy of oral antiplatelet agents in STEMI patients has been questioned, mainly because of their delayed onset of action in the clinical setting of ST-segment elevation myocardial infarction and the recently described adverse effect of morphine on their pharmacodynamic/pharmacokinetic profile. Whether these agents should be administered beyond 1 year after the index event is also under discussion, as there is clinical evidence that prolonged administration may be associated with clinical benefit. Use of oral P2Y12 inhibitors in patients with ST-segment elevation myocardial infarction still faces questions and future research is needed to establish which, when and how should be administered in this clinical setting.

  19. Inflammatory bowel disease imaging: Current practice and future directions.

    Science.gov (United States)

    Kilcoyne, Aoife; Kaplan, Jess L; Gee, Michael S

    2016-01-21

    The purpose of this paper is to evaluate the role of imaging in inflammatory bowel disease (IBD), including detection of extraluminal complications and extraintestinal manifestations of IBD, assessment of disease activity and treatment response, and discrimination of inflammatory from fibrotic strictures. IBD is a chronic idiopathic disease affecting the gastrointestinal tract that is comprised of two separate, but related intestinal disorders; Crohn's disease and ulcerative colitis. The paper discusses, in detail the pros and cons of the different IBD imaging modalities that need to be considered in order to optimize the imaging and clinical evaluation of patients with IBD. Historically, IBD evaluation of the bowel has included imaging to assess the portions of the small bowel that are inaccessible to optical endoscopic visualization. This traditionally was performed using barium fluoroscopic techniques; however, cross-sectional imaging techniques (computed tomography and magnetic resonance imaging) are being increasingly utilized for IBD evaluation because they can simultaneously assess mural and extramural IBD manifestations. Recent advances in imaging technology, that continue to improve the ability of imaging to noninvasively follow disease activity and treatment response, are also discussed. This review article summarizes the current imaging approach in inflammatory bowel disease as well as the role of emerging imaging modalities.

  20. Jejunostomy after oesophagectomy: a review of evidence and current practice.

    Couper, Graeme

    2011-08-01

    Patients undergoing oesophagectomy often have nutritional needs at the time of diagnosis and in the post-operative period. The aim of this article is to review the current literature and report on the author's experience of routine feeding jejunostomy insertion following oesophagectomy. The records of forty-eight consecutive patients undergoing oesphagectomy under the author's care were reviewed. Although the evidence of benefit of peri-operative feeding in patients undergoing oesophagectomy is limited, there is a clear need to establish a feeding route at the time of surgery. Oesophagectomy is associated with a mortality rate of 5-10% and a morbidity rate of 30-40% even in high-volume specialist centres. Over 50% of patients developing complications will require an alternative to oral feeding beyond 30 d. The enteral route is preferred in terms of safety and cost. A surgical feeding jejunostomy is associated with a low complication rate and a mortality rate of less than 1%. In forty-eight patients undergoing oesophagectomy the average weight loss at 6 months was 8·4 kg with only 8% regaining their pre-operative weight. Large reductions in weight at 6 months post-operatively were recorded irrespective of the development of post-operative complications or early recurrent disease. Routine jejunostomy insertion is recommended to ensure adequate nutrition in patients who develop post-operative complications and for those patients with long-term reduced appetite and poor oral intake.

    2017-08-01

    Liberia is endowed with an impressive stock of mineral reserves and has traditionally relied on mining, namely iron ore, gold, and diamonds, as a major source of income. The recent growth in the mining sector has the potential to contribute significantly to employment, income generation, and infrastructure development. However, the development of these mineral resources has significant environmental impacts that often go unnoticed. This paper presents an overview of the Liberian mining sector from historical, current development, and economic perspectives. The efforts made by government to address issues of environmental management and sustainable development expressed in national and international frameworks, as well as some of the environmental challenges in the mining sector are analyzed. A case study was conducted on one of the iron ore mines (China Union Bong Mines Investment) to analyze the effects of the water quality on the local water environment. The results show that the analyzed water sample concentrations were all above the WHO and Liberia water standard Class I guidelines for drinking water. Finally the paper examines the application of water footprint from a life cycle perspective in the Liberian mining sector and suggests some policy options for water resources management.

    2016-03-01

    Full Text Available The paper is concerned with the problem of preschool education in Russia and the Vologda region. It shows that in the current context of shortage of places in state nurseries it is necessary to develop private care service providers. Day-care is in great demand among parents having children at the ages from 1 to 3. The paper analyses the main characteristics of preschool educational organi-zations. It shows that in the Vologda region, particularly in Vologda, private demand for preschool education service is to a wide extent unsatisfied. In Vologda more than ten thousand children are on waiting lists for preschool educational organizations. In total, in the Vologda region the list numbers about 28.9 thousand children, 34% of them are registered in Vologda. The paper provides the results of the study into Vologda private nurseries and day-care carried out in May-June 2015 by using the method of involved observation. It reveals key factors hampering growth of private nurseries.It is noted that one of the factors is the lack of license for educational activities and motivation for most entrepreneurs to obtain it. The results show that unlicensed gardens are not controlled by the authorities and public organizations. Interaction between the private institutions of pre-school education is not provided as well. We can observe that some private sector organizations do not meet the requirement of health and safety standards and impose limiting measures for the sake of children health such as organization of walks due to the absence of a secure walking site. High amount of parental fee is also found out.It offers directions for the development of private preschool education service

    2014-09-01

    Full Text Available Design driven innovation has emerged to be an alternative way to generate sustainable competitive products or services. Previous research has recently revealed succesful practices of design driven innovation in various industries. However, little has been known about the creative companies that practice design driven innovation, especially in developing countries. This research investigates the existence and practices of design-driven innovation in the Indonesian creative industry. Based on interviews with the design-preneurs of the creative industry, one of the results of this study reveals how the Indonesian creative industry creates new meanings that are embedded into new products. Based on the identification, a framework to create new meaningsis resulted which consists of a set of key processes, such as sensing, sensemaking, specifying, setting up and storytelling. The practical contribution of this research is that this identified framework can be adopted by any creative companies interested in improving their innovation capability.

    Chuenmanee, Chanoknat; Thathong, Kongsak

    2018-01-01

    Multiple representations have been widely used as a reasoning tool for understanding complex scientific concepts. Thus this study attempted to investigate the current practice of using multiple representations on Year 4 science classrooms in terms of modes and levels which appear in curriculum documents, teaching plans, tasks and assessments, teaching practices, and students' behaviors. Indeed, documentary analysis, classroom observation, and interview were used as the data collection methods. First of all, Year 4 science documents were analyzed. Then classroom observation was used as a collecting method to seek what actually happen in the classroom. Finally, in-depth interviews were used to gather more information and obtain meaningful data. The finding reveals that many modes of verbal, visual, and tactile representations within three levels of representations are posed in Year 4 documents. Moreover, according to classroom observations and interviews, there are three main points of applying multiple representations into classrooms. First of all, various modes of representations were used, however, a huge number of them did not come together with the levels. The levels of representations, secondly, macroscopic and cellular levels were introduced into all classrooms while symbolic level was provided only in some classrooms. Finally, the connection of modes and levels pointed out that modes of representations were used without the considerations on the levels of them. So, it seems to be that teaching practice did not meet the aims of curriculum. Therefore, these issues were being considered in order to organize and design the further science lessons.

    Young adults with intellectual disability (ID) continue to experience the least successful postschool outcomes among transition-aged youth ( Sanford et al., 2011 ). Experts disagree on the most effective approach to improve outcomes such as employment, postsecondary education, and community living. In 2015, the National Goals Conference brought together educational researchers to set an agenda to guide the field in terms of research, practice, and policy ( Thoma, Cain, & Walther-Thomas, 2015 ). One of their recommendations, based on promising research and practices, urged the field to identify effective personnel preparation and professional development practices that ensure general and special educators can implement a UDL framework ( Thoma, Cain, et al., 2015 ). This study surveyed program coordinators at accredited universities to determine what is currently being done to prepare educators to implement a Universal Design for Learning (UDL) framework, the extent to which a UDL framework is being incorporated into preservice courses in higher education, and how a UDL framework is being used to improve postschool outcomes for youth with ID.

    Full Text Available Abstract Background Maternal outcomes in most countries of the developed world are good. However, in many developing/resource-poor countries, maternal outcomes are bleaker: Every year, more than 500,000 women die in childbirth, mostly in resource-poor countries. Those who survive often suffer from severe and long-term morbidities. One of the most devastating injuries is obstetric fistula, occurring most often in south Asia and sub-Saharan Africa. Fistula treatment and care are available in many countries across Africa and Asia, but there is a lack of reliable data around clinical factors associated with the success of fistula repair surgery. Most published research has been retrospective. While these studies have provided useful information about the care and treatment of fistula, they are limited by the design. This study was designed to identify practices in care that could lead to the design of prospective and randomized controlled trials. Methods Self-administered questionnaires were completed by 40 surgeons known to provide fistula treatment services in Africa and Asia at private and government hospitals. The questionnaire was divided into three parts to address the following issues: prophylactic use of antibiotics before, during, and after fistula surgery; urethral catheter management; and management practices for patients with urinary incontinence following fistula repair. Results The results provide a glimpse into current practices in fistula treatment and care across a wide swath of geographic, economic, and organizational considerations. There is consensus in treatment in some areas (routine use of prophylactic antibiotics, limited bed rest until the catheter is removed, nonsurgical treatment for postsurgical incontinence, while there are wide variations in practice in other areas (duration of catheter use, surgical treatments for postsurgical incontinence. These findings are based on a small sample and do not allow for recommending

  16. Design of Smart Charging Infrastructure Hardware and Firmware Design of the Various Current Multiplexing Charging System

    Energy Technology Data Exchange (ETDEWEB)

    Chung, Ching-Yen; Chu, Peter; Gadh, Rajit

    2013-10-07

    Currently, when Electric Vehicles (EVs) are charging, they only have the option to charge at a selected current or not charge. When during the day there is a power shortage, the charging infrastructure should have the options to either shut off the power to the charging stations or to lower the power to the EVs in order to satisfy the needs of the grid. There is a need for technology that controls the current being disbursed to these electric vehicles. This paper proposes a design for a smart charging infrastructure capable of providing power to several EVs from one circuit by multiplexing power and providing charge control. The smart charging infrastructure includes the server and the smart charging station. With this smart charging infrastructure, the shortage of energy in a local grid could be solved by our EV management system

  19. Researcher Practice: Embedding Creative Practice Within Doctoral Research in Industrial Design

    Directory of Open Access Journals (Sweden)

    Mark Evans

    2010-01-01

    Full Text Available This article considers the potential for a researcher to use their own creative practice as a method of data collection. Much of the published material in this field focuses on more theoretical positions, with limited use being made of specific PhDs that illustrate the context in which practice was undertaken by the researcher. It explores strategies for data collection and researcher motivation during what the author identifies as "researcher practice." This is achieved through the use of three PhD case studies. Methods of data collection focus on: (a the use of output from practice for quantitative data collection (i.e., for comparative analysis, (b the use of output from practice for qualitative data collection (i.e., reflection on new working practice, and (c the use of output from practice for data translation (i.e., using research output to produce a creative design solution for a tool that can be used for further data collection and validation. The article discusses the methodologies employed in the case studies to identify themes which enable the definition of a generic researcher practitioner methodology. It notes the significance of creative practice in support of data collection and the differences between researcher practice and commercial practice, and emphasises the contribution of researcher practice towards personal motivation.

    2001-12-15

    I address 2 important topics of current good manufacturing practices as they apply to vaccine products: product inspections and stability testing. The perspective presented is that of regulated industry. There are 2 major categories of product/facility inspections: those occurring before licensure of a vaccine product and those occurring after a vaccine product is licensed. The logistics and focus of each inspection type, the preapproval inspection, and the required biennial inspection are discussed, as are guidance and recommendations for achieving successful inspections. The requirements, guidance, and recommendations regarding the type, amount, and extensiveness of stability data for vaccine products are presented. The discussion details the potential differences in the amount and type of data required for products that are not yet licensed versus marketed products. Guidance, from a regulated industry perspective, regarding the design and implementation of a successful stability program is also discussed.

    governments but they also pose new challenges for policy-makers and public administrators who are not yet familiar with design concepts, principles and methods beyond problem-solving. Despite the many linkages between and among design, designing, policy-making and policy implementation, we have yet to clarify...... how and what makes design relevant to policy-makers and public managers. Although policy-making, in its essence, constitutes a design activity, policy-making is not widely discussed in design terms. Literature on policy-making processes and policy design has treated design almost exclusively...... that could “achieve more humanizing outcomes” (Lynch 1965) and meaningfully transform government. Problem-solving design is then contrasted with design as inquiry. The paper concludes that a more sophisticated understanding of design concepts, methods and practices in policy-making is a condition...

  12. Quasi-experimental designs in practice-based research settings: design and implementation considerations.

    Science.gov (United States)

    Handley, Margaret A; Schillinger, Dean; Shiboski, Stephen

    2011-01-01

    Although randomized controlled trials are often a gold standard for determining intervention effects, in the area of practice-based research (PBR), there are many situations in which individual randomization is not possible. Alternative approaches to evaluating interventions have received increased attention, particularly those that can retain elements of randomization such that they can be considered "controlled" trials. Methodological design elements and practical implementation considerations for two quasi-experimental design approaches that have considerable promise in PBR settings--the stepped-wedge design, and a variant of this design, a wait-list cross-over design, are presented along with a case study from a recent PBR intervention for patients with diabetes. PBR-relevant design features include: creation of a cohort over time that collects control data but allows all participants (clusters or patients) to receive the intervention; staggered introduction of clusters; multiple data collection points; and one-way cross-over into the intervention arm. Practical considerations include: randomization versus stratification, training run in phases; and extended time period for overall study completion. Several design features of practice based research studies can be adapted to local circumstances yet retain elements to improve methodological rigor. Studies that utilize these methods, such as the stepped-wedge design and the wait-list cross-over design, can increase the evidence base for controlled studies conducted within the complex environment of PBR.

    2012-11-01

    Single-subject experimental designs (SSEDs) represent an important tool in the development and implementation of evidence-based practice in communication sciences and disorders. The purpose of this article is to review the strategies and tactics of SSEDs and their application in speech-language pathology research. The authors discuss the requirements of each design, followed by advantages and disadvantages. The logic and methods for evaluating effects in SSED are reviewed as well as contemporary issues regarding data analysis with SSED data sets. Examples of challenges in executing SSEDs are included. Specific exemplars of how SSEDs have been used in speech-language pathology research are provided throughout. SSED studies provide a flexible alternative to traditional group designs in the development and identification of evidence-based practice in the field of communication sciences and disorders.

  14. Runtime reconfiguration in networked embedded systems design and testing practices

    CERN Document Server

    Exarchakos, George

    2016-01-01

    This book focuses on the design and testing of large-scale, distributed signal processing systems, with a special emphasis on systems architecture, tooling and best practices. Architecture modeling, model checking, model-based evaluation and model-based design optimization occupy central roles. Target systems with resource constraints on processing, communication or energy supply require non-trivial methodologies to model their non-functional requirements, such as timeliness, robustness, lifetime and “evolution” capacity. Besides the theoretical foundations of the methodology, an engineering process and toolchain are described. Real-world cases illustrate the theory and practice tested by the authors in the course of the European project ARTEMIS DEMANES. The book can be used as a “cookbook” for designers and practitioners working with complex embedded systems like sensor networks for the structural integrity monitoring of steel bridges, and distributed micro-climate control systems for greenhouses and...

  15. Authorship and publication practices in the social sciences: historical reflections on current practices.

    Science.gov (United States)

    Bebeau, Muriel J; Monson, Verna

    2011-06-01

    An historical review of authorship definitions and publication practices that are embedded in directions to authors and in the codes of ethics in the fields of psychology, sociology, and education illuminates reasonable agreement and consistency across the fields with regard to (a) originality of the work submitted, (b) data sharing, (c) human participants' protection, and (d) conflict of interest disclosure. However, the role of the professional association in addressing violations of research or publication practices varies among these fields. Psychology and sociology provide active oversight with sanction authority. In education, the association assumes a more limited role: to develop and communicate standards to evoke voluntary compliance. With respect to authorship credit, each association's standards focus on criteria for inclusion as an author, other than on the author's ability to defend and willingness to take responsibility for the entire work. Discussions across a broad range of research disciplines beyond the social sciences would likely be beneficial. Whether improved standards will reduce either misattribution or perceptions of inappropriate attribution of credit within social science disciplines will likely depend on how well authorship issues are addressed in responsible conduct of research education (RCR), in research practice, and in each association's ongoing efforts to influence normative practice by specifying and clarifying best practices.

  16. A comparison of methods currently used in inclusive design.

    Science.gov (United States)

    Goodman-Deane, Joy; Ward, James; Hosking, Ian; Clarkson, P John

    2014-07-01

    Inclusive design has unique challenges because it aims to improve usability for a wide range of users. This typically includes people with lower levels of ability, as well as mainstream users. This paper examines the effectiveness of two methods that are used in inclusive design: user trials and exclusion calculations (an inclusive design inspection method). A study examined three autoinjectors using both methods (n=30 for the user trials). The usability issues identified by each method are compared and the effectiveness of the methods is discussed. The study found that each method identified different kinds of issues, all of which are important for inclusive design. We therefore conclude that a combination of methods should be used in inclusive design rather than relying on a single method. Recommendations are also given for how the individual methods can be used more effectively in this context. Copyright © 2013 Elsevier Ltd and The Ergonomics Society. All rights reserved.

  17. Application of ultimate limit state design for axially loaded single piles in Egyptian geotechnical practice

    Directory of Open Access Journals (Sweden)

    Yasser M. El-Mossallamy

    2017-08-01

    Full Text Available For a long time, the framework of geotechnical design in Egypt has been based mainly on Working Stress Design (WSD philosophy with the global safety concept as presented in the current version of the Egyptian Code of Practice for Soil Mechanics and Foundations Design and Construction [1]. This design philosophy is supported by long-term experience, considering local experiences and is adopted to fulfill the required safety margin. Limit State Design (LSD philosophy, on the other side, has already been applied for the design of reinforced concrete structures as introduced in the Egyptian Code of Practice for the Design and Construction of Reinforced Concrete Structures [2]. Applying LSD for superstructure and WSD for foundations often results in design misleading because of the incompatibility between the two design philosophies. Accordingly, implementation of LSD philosophy for geotechnical designs in Egypt has become mandatory and the transition to this new design philosophy of LSD should be as smooth and gradual as possible to allow for a better acceptance by the Egyptian geotechnical community. LSD philosophy using partial safety factors has been applied worldwide using two different approaches; factored strength approach and factored resistance approach. During this study, resistance reduction factors are calibrated on the basis of calibration-by-fitting technique, to be used with factored resistance approach for axially loaded single piles. The calibrated resistance reduction factors from this study are found to be relatively consistent with those values adopted in other geotechnical design codes worldwide.

  1. Playful Collaborative Exploration: New Research Practice in Participatory Design

    Directory of Open Access Journals (Sweden)

    Martin Johansson

    2005-01-01

    Full Text Available Within the Participatory Design community as well as the Computer Supported Cooperative Work tradition, a lot of effort has been put into the question of letting field studies inform design. In this paper, we describe how game-like approaches can be used as a way of exploring a practice from a design point of view. Thinking of ethnographic fieldwork as a base for sketching, rather than descriptions, creates openness that invites collaborative authoring. The concept of playful collaborative exploration suggests certain ways of interacting with material from field studies so that it becomes a design material for an open-ended design process. We have carried out field studies, transformed the field material into design material, and set up a design game for working with it together with the people we followed in the field. The design game builds on an idea about the power of narratives and the benefits of constraining rules. We believe that this framework for collaboration opens for playfulness, experimentation, and new design ideas.

    2017-11-01

    Cervicofacial infections are common emergency presentations to maxillofacial departments in the UK, there is no consensus about their management and, in particular, the role of corticosteroids is not clear. Our aim was to find out the current practice of UK maxillofacial surgeons in managing these infections using a multicentre questionnaire study. The questionnaire was designed, piloted, and revised before distribution, and questions were asked to assess preoperative, operative, and postoperative management. It was distributed to maxillofacial surgeons throughout the UK through the Maxillofacial Research Trainee Collaborative (MTReC) network, and at the 2016 British Association of Oral and Maxillofacial Surgeons (BAOMS) Junior Trainees Group conference. A total of 350 questionnaires were distributed to 17 maxillofacial units. Eighty-six questionnaires were distributed at the BAOMS Junior Trainee conference. An overall response rate of 92% (n=324) was achieved. The results showed that there were important differences in reported practice between and within maxillofacial units in the UK in managing these infections. The antibiotic regimens and use of steroids varied widely. Twenty-three per cent of respondents had to wait over 24hours for access to emergency theatres. However, these results provide no hard evidence for or against the use of corticosteroids in cervicofacial infections. Copyright © 2017 The British Association of Oral and Maxillofacial Surgeons.

    Read, Gemma J M; Salmon, Paul M; Lenné, Michael G; Stanton, Neville A

    2015-01-01

    Cognitive work analysis (CWA) is a framework of methods for analysing complex sociotechnical systems. However, the translation from the outputs of CWA to design is not straightforward. Sociotechnical systems theory provides values and principles for the design of sociotechnical systems which may offer a theoretically consistent basis for a design approach for use with CWA. This article explores the extent to which CWA and sociotechnical systems theory offer complementary perspectives and presents an abstraction hierarchy (AH), based on a review of literature, that describes an 'optimal' CWA and sociotechnical systems theory design system. The optimal AH is used to assess the extent to which current CWA-based design practices, uncovered through a survey of CWA practitioners, aligns with sociotechnical systems theory. Recommendations for a design approach that would support the integration of CWA and sociotechnical systems theory design values and principles are also derived.

    Tierney, Joshua; Baucom, Rebeccah B; Holzman, Michael D; Poulose, Benjamin K; Pierce, Richard A

    2017-04-01

    The diagnostic and therapeutic roles for endoscopic intervention are expanding. To continue emphasis on endoscopy in surgical training, The Society of American Gastrointestinal and Endoscopic Surgeons has developed the Fundamentals of Endoscopic Surgery (FES) course to standardize and assess endoscopy training. However, little demographic information exists about the current practice of endoscopy by general surgeons and how to best integrate endoscopic skills into surgical training. A survey to collect data regarding the current practice patterns of endoscopy was sent to surgeons with a valid email address in the American Medical Association masterfile. Information regarding the type of training (academic vs. community general surgery residency) and current practice environment (academic medical center vs. community hospital) was collected. The respondents' current practice volume of upper endoscopy and colonoscopy over the prior year was stratified into three groups: rare (10 per month). Pearson's Chi-squared test was used to analyze the data. The survey was sent to 9902 general surgeons. There were 767 who provided answers regarding their current practice of endoscopy. Mean time in practice was 18 ± 10 years, 87 % were male, and 83 % practiced in a metropolitan area. Respondents who trained at academic general surgery programs were less likely than those at community programs to frequently perform colonoscopy (17.3 vs. 27.9 %, p endoscopy (11.8 vs. 17.1 %, p endoscopy (9.8 vs. 14.8 %, p < 0.05) than those who practice at community hospitals. The type of residency training and current practice setting of general surgeons has a significant influence on the volume of endoscopic procedures performed. This study identifies areas where more emphasis on endoscopic skills training is needed, such as FES.

  16. Feline transfusion practice in South Africa : current status and practical solutions : continuing education

    Directory of Open Access Journals (Sweden)

    T. Dippenaar

    1999-07-01

    Full Text Available Blood transfusion therapy is often under-utilised in feline practice in South Africa. However, it is a technique that can be safely and effectively introduced in practice. Cats have naturally occurring allo-antibodies against the blood type that they lack, which makes blood typing, or alternatively cross-matching, essential before transfusions. Feline blood donors must be carefully selected, be disease free and should be sedated before blood collection. The preferred anticoagulant for feline blood collection is citrate-phosphatedextrose-adenine. Blood can either be administered intravenously or into the medullary cavity, with the transfusion rate depending on the cat's hydration status and cardiac function. Transfusion reactions can be immediate or delayed and they are classified as immunological or non-immunological. Indications, methods and techniques to do feline blood transfusions in a safe and economical way are highlighted.

  17. Mobile and Social: Ten Best Practices for Designing Mobile Applications

    Directory of Open Access Journals (Sweden)

    Liviu LICA

    2010-01-01

    Full Text Available This paper gives ten best practices for designing mobile applications that have social-networking functions. The need for such an approach is given by the rapid growth in impor-tance of both social networks and mobile applications. In order to make it easy to follow where the best practices come from, the paper starts with a look at why social networks are more than just a buzz word and at how the field of mobile applications is evolving. It also shows how and why the two fields go together so well. To further make the point, there is a case study of four interesting mobile applications that are textbooks examples of successful applications. The best practices are based on research done for this article and on the extensive knowledge of the author.

  18. A survey of current practices in management of Hirschsprung′s disease in Nigeria

    Directory of Open Access Journals (Sweden)

    Abdulrasheed A. Nasir

    2014-01-01

    Full Text Available Background: Although there are several modalities of treatment for Hirschsprung′s disease (HD, there are presently no clear guidelines on treatment of the condition by paediatric surgeons in Nigeria. This survey determines the current approach to treatment among Nigerian paediatric surgeons and should help in establishing a consensus and guidelines for care in this and similar setting. Materials and Methods: An online questionnaire was designed using survey Monkey ® to determine current clinical and operative management of patients with HD by consultant paediatric surgeons practicing in the Nigeria. The paediatric surgeons were notified by E-mail, which included a link to the survey on survey Monkey ® . The survey was also administered at the 12 th annual meeting of Association of Paediatric Surgeons of Nigeria in September, 2013, to capture those who did not complete the online survey. Thirty-one paediatric surgeons from 21 different tertiary paediatric surgery centres completed the survey. Results: Sixteen (52% respondents see up to 20% of their patients with HD in the neonatal period. Twenty-six (84% respondents do routine barium enema. Twenty six (84% respondents do full thickness rectal biopsy under general anaesthesia (GA. There was no consistency in operative techniques, with transabominal Swenson′s operation being practiced by 17 (57% respondents and 11 (37% transanal endorectal pull through. 14 (45% do pull through at any age. 12 (39% respondents do more than half of their patient as primary pull through. Conclusion: Full thickness rectal biopsy under GA is still the vogue with variations in the surgical technique for management of Hirshsprung′s disease in Nigeria. Primary pull through procedures is becoming increasingly popular. There′s a need for Paediatric Surgeons in Nigeria to come up with a guideline on management of HD, to guide trainees and other surgeons in the care of these patients.

  19. Gestational diabetes mellitus in Europe: prevalence, current screening practice and barriers to screening.

    LENUS (Irish Health Repository)

    Buckley, B S

    2011-12-12

    Background:  Gestational diabetes mellitus is a potentially serious condition that affects many pregnancies and its prevalence is increasing. Evidence suggests early detection and treatment improves outcomes, but this is hampered by continued disagreement and inconsistency regarding many aspects of its diagnosis. Methods:  The Vitamin D and Lifestyle Intervention for Gestational Diabetes Mellitus Prevention (DALI) research programme aims to promote pan-European standards in the detection and diagnosis of gestational diabetes and to develop effective preventive interventions. To provide an overview of the context within which the programme will be conducted and its findings interpreted, systematic searching and narrative synthesis have been used to identify and review the best available European evidence relating to the prevalence of gestational diabetes, current screening practices and barriers to screening. Results:  Prevalence is most often reported as 2-6% of pregnancies. Prevalence may be lower towards the Northern Atlantic seaboard of Europe and higher in the Southern Mediterranean seaboard. Screening practice and policy is inconsistent across Europe, hampered by lack of consensus on testing methods, diagnostic glycaemic thresholds and the value of routine screening. Poor clinician awareness of gestational diabetes, its diagnosis and local clinical guidelines further undermine detection of gestational diabetes. Conclusions:  Europe-wide agreement on screening approaches and diagnostic standards for gestational diabetes could lead to better detection and treatment, improved outcomes for women and children and a strengthened evidence base. There is an urgent need for well-designed research that can inform decisions on best practice in gestational diabetes mellitus screening and diagnosis. © 2011 The Authors.

    To describe current practices for manual wheelchair (MWC) skills training in Canadian rehabilitation centers. An online survey was sent to practice leaders in occupational (OT) and physical therapy (PT) at 87 Canadian rehabilitation centers. Responses were solicited from individuals who could report about wheelchair skills training at facilities with at least 10 beds designated for rehabilitation. Thirty-four questions asked about: (1) demographics, (2) components of MWC training, (3) amount of MWC skills training, (4) use of validated programs and (5) perceived barriers to using validated programs. Data were analyzed using summary statistics. About 68/87 responses were received primarily from OTs (42/68). Basic MWC skills training (e.g. wheel-locks) was consistently part of clinical practice (45/68), while advanced skills training (e.g. curb-cuts) was rare (8/68). On an average, 1-4 h of training was done (29/68). Validated training programs were used by 16/68, most of whom used them "rarely" (7/16). Common barriers to using validated programs were lack of time (43/68) and resources (39/68). Learning to use a wheelchair is important for those with ambulation impairments because the wheelchair enables mobility and social participation. Providing opportunities for advanced wheelchair skills training may enhance mobility and social participation in a safe manner. Implications for Rehabilitation There is evidence confirming the benefits of a validated wheelchair skills program, yet most clinicians do no not use them. A variety of perceived barriers may help to explain the limited use of existing programs, such as time, resources and knowledge. Effective knowledge translation efforts may help alleviate some of these barriers, and novel wheelchair training approaches may alleviate some burden on clinicians to help accommodate the increasing number of older wheelchair users.

  1. Current issues in the design of running and court shoes.

    This review paper focuses on the three most important functional design factors for sport shoes: injury prevention, performance and comfort. Concepts for these design factors are discussed for running and court shoes. For running shoes, pronation control and cushioning are still considered to be the key concepts for injury prevention despite the fact that conclusive clinical and epidemiological evidence is missing to show the efficacy of these design strategies. Several design features have been proposed to be effective in controlling the amount of pronation. However, the kinematic effects of such features seem to be subject-specific and rather small especially when looking at the actual skeletal motion. Recent running shoe research suggests that cushioning may not or only marginally be related to injuries and that cushioning during the impact phase of running may be more related to aspects such as comfort, muscle tuning or fatigue. For court shoes, lateral stability, torsional flexibility, cushioning and traction control appear to be important design strategies to decrease the risk of injury. With respect to running performance, the shoe concepts of weight reduction, efficiency and energy return are discussed. The concept of energy return does not seem to be a feasible concept whereas concepts which aim to minimize energy loss appear to be more promising and successful, e.g. weight reduction, reduction of muscle energy required for stabilization. For court shoes, optimal traction seems to be the key factor for performance. Research in the area of shoe comfort is still sparse. Cushioning, fitting and climate concepts appear to improve the comfort of both running and court shoes. Many investigations in the area of sport shoe research have shown that subject-specific responses can be expected. Different groups of athletes may require different types of shoes. The definition of these grouping characteristics and their design needs seem to be the most important

    2012-09-12

    Current societal and healthcare system trends highlight the need to transform nursing education to prepare nurses capable of outstanding practice in the 21st century. Patricia Benner and colleagues urged nurse educators to transform their practice in the 2010 publication Educating Nurses, A Call to Radical Transformation. Frequently utilized pedagogical frameworks in nursing education include behaviorism and constructivism. Much of the structure and basis for instruction and evaluation can be found rooted in these philosophies. By first exploring both behaviorism and constructivism and then relating their use in nursing education to the call to transform, educators can be encourage to examine current practice and possibly modify aspects to include more rich experiential learning.

    In oncologic practice, treatment guidelines provide appropriate treatment strategies based on evidence. Currently, many guidelines are used, including those of the European Association for the Study of the Liver and European Organization for Research and Treatment of Cancer (EASL-EORTC), National Comprehensive Cancer Network (NCCN), Asia-Pacific Primary Liver Cancer Expert (APPLE), and Korean Liver Cancer Study Group and National Cancer Centre (KLCSG-NCC). Although radiotherapy is commonly used in clinical practice, some guidelines do not accept it as a standard treatment modality. In this review, we will investigate the clinical practice guidelines currently used, and discuss the application of radiotherapy.

    The use of checklists to minimise errors is well established in high reliability, safety-critical industries. In health care there is growing interest in checklists to standardise checking processes and ensure task completion, and so provide further systemic defences against error and patient harm. However, in UK general practice there is limited experience of safety checklist use. To identify workplace hazards that impact on safety, health and wellbeing, and performance, and codesign a standardised checklist process. Application of mixed methods to identify system hazards in Scottish general practices and develop a safety checklist based on human factors design principles. A multiprofessional 'expert' group (n = 7) and experienced front-line GPs, nurses, and practice managers (n = 18) identified system hazards and developed and validated a preliminary checklist using a combination of literature review, documentation review, consensus building workshops using a mini-Delphi process, and completion of content validity index exercise. A prototype safety checklist was developed and validated consisting of six safety domains (for example, medicines management), 22 sub-categories (for example, emergency drug supplies) and 78 related items (for example, stock balancing, secure drug storage, and cold chain temperature recording). Hazards in the general practice work system were prioritised that can potentially impact on the safety, health and wellbeing of patients, GP team members, and practice performance, and a necessary safety checklist prototype was designed. However, checklist efficacy in improving safety processes and outcomes is dependent on user commitment, and support from leaders and promotional champions. Although further usability development and testing is necessary, the concept should be of interest in the UK and internationally. © British Journal of General Practice 2015.

    The Design for Usability project aims at improving the usability of electronic professional and consumer products by creating new methodology and methods for user-centred product development, which are feasible to apply in practice. The project was focused on 5 key areas: (i) design methodology, expanding the existing approach of scenario-based design to incorporate the interaction between product design, user characteristics, and user behaviour; (ii) company processes, barriers and enablers for usability in practice; (iii) user characteristics in relation to types of products and use-situations; (iv) usability decision-making; and (v) product impact on user behaviour. The project team developed methods and techniques in each of these areas to support the design of products with a high level of usability. This paper brings together and summarizes the findings.

    To acquire professional competences that entail performance of complex skills, an authentic learning environment is required focused on the integration of all aspects of competences. However, most educational programmes offer separate building blocks, such as separate modules for knowledge and skills. Students accumulate what they have learned in these modules as they progress through the curriculum. In this paper the authors advocate the Four-Component Instructional Design model (4C/ID), which offers a whole-task approach to course design for programmes in which students learn complex skills. The four core components of this approach are: learning tasks, supportive information, just-in-time information and part-task practice. A concrete example from medical education will be presented to clarify both the general ideas behind this approach and the differences between the whole-task approach and conventional educational designs.

    Full Text Available Purpose: The fight against Healthcare-associated infections is a public health priority and a major challenge for the safety and quality of care. The objective was to assess hygiene in general practitioners′ (GPs′ office and identify barriers to and drivers for better practice. Materials and Methods: We performed a cross-sectional study in which a questionnaire was sent to a randomly selected, representative sample of 800 GPs. We used a self-administered questionnaire. The first part assessed current practice and the second part focused on barriers and motivating factors for better practice. We performed a descriptive statistical analysis of the responses to closed questions and a qualitative analysis of the responses to open-ended questions. Results: Only a third of the GPs were aware of the current guidelines. Disposable equipment was used by 31% of the GPs. For the remainder, only 38% complied with the recommended procedures for sterilisation or disinfection. Seventy-two percent of the GPs washed their hands between consultations in the office. A significant minority of physicians disregarded the guidelines by never wearing gloves to perform sutures (11%, treat wounds (10%, fit intrauterine devices (18% or perform injections (18%. The main barriers to good practice were the high cost of modifications and lack of time/space. Two third of the GPs did not intend to change their practices. The drivers for change were pressure from patients (4.8 on a scale of 1 to 7, inspection by the health authorities (4.8 and the fear of legal action (4.4. Conclusions: Our results show that there are significant differences between current practice and laid-down professional guidelines. Policies for improvement of hygiene must take into account barriers and motivating factors.

    Research concerning child feeding practices has focused on children and adolescents, and little is known about how feeding practices used in childhood relate to eating behaviors and weight status in early adulthood. We assessed college students' and their parents' retrospective reports of child feeding practices used when the students were in middle childhood. We also assessed the college students' current reports of their eating behaviors using the Dutch Eating Behavior Questionnaire (DEBQ) and the Intuitive Eating Scale (IES), and measured their current BMI. Results showed that college students' and their parents' reports about previous parental use of child feeding practices were not correlated. Parent reports of their own use of child feeding practices were more related to students' eating behaviors and BMI than were students' recollections about feeding practices used by their parents. An analysis of gender effects showed that there were positive correlations between parental child feeding practices, BMI, and emotional eating for female students. These relationships did not exist for male students. The results suggest that child feeding practices recollected by parents are linked to the development of emotional eating and weight status of women in early adulthood.

    2017-11-01

    The effectiveness of the implementation of construction waste reduction through 3R reflects the sustainability in construction waste management. Weak implementation of construction waste reduction through 3R among contractors will lead to unsustainable construction waste management. Increase in construction waste on landfills is critical especially on islands where land is very limited for solid waste disposal. This aim of this paper is to investigate current practice of construction waste reduction through 3R practice among contractors in Penang, Malaysia. The findings reported herein is based on feedbacks from 143 construction contractors of grade CIDB G7, G6 and G5 in Penang and experts from Penang Local Authority, CIDB in Penang and its Headquarters, National Solid Waste Management Department, and Headquarters of Solid Waste and Public Cleansing Management Corporation. Interviews and questionnaire surveys have been found that 3R practice is not mandatory in construction waste management in Penang. Only 39.8% construction contractors practiced 3R in managing their waste. Therefore, 3R practices should be emphasized in construction industry. Reducing wastes through 3R practices in construction industry is a way forward towards sustainable construction waste management especially in expanding the lifetime of landfill.

    The current practice of peer review within radiology is well developed and widely implemented compared with other medical specialties. However, there are many factors that limit current peer review practices from reducing diagnostic errors and improving patient care. The development of "meaningful peer review" requires a transition away from compliance toward quality improvement, whereby the information and insights gained facilitate education and drive systematic improvements that reduce the frequency and impact of diagnostic error. The next generation of peer review requires significant improvements in IT functionality and integration, enabling features such as anonymization, adjudication by multiple specialists, categorization and analysis of errors, tracking, feedback, and easy export into teaching files and other media that require strong partnerships with vendors. In this article, the authors assess various peer review practices, with focused discussion on current limitations and future needs for meaningful peer review in radiology.

The paper also discusses some of the issues surrounding abortion in NI and seeks to explain why this subject is causing controversy and debate, especially following a judicial review in February and Marie Stopes opening a termination service in Belfast.

  18. Design of Speed and Current Controllers Based on Online Particle Swarm Optimization Method for IPMSM Drives

    Directory of Open Access Journals (Sweden)

    Song Zhengqiang

    2016-01-01

    Full Text Available In this paper, a novel online particle swarm optimization method is proposed to design speed and current controllers of vector controlled interior permanent magnet synchronous motor drives considering stator resistance variation. In the proposed drive system, the space vector modulation technique is employed to generate the switching signals for a two-level voltage-source inverter. The nonlinearity of the inverter is also taken into account due to the dead-time, threshold and voltage drop of the switching devices in order to simulate the system in the practical condition. Speed and PI current controller gains are optimized with PSO online, that means single irritation optimization computation can be completed within single sample time. In addition, the fitness function is changed according to the system dynamic and steady states. The proposed optimization algorithm is compared with conventional PI control method in the condition of step speed change and stator resistance variation, showing that the proposed online optimization method has better robustness and dynamic characteristics compared with conventional PI controller design.

  20. Experimental Verification of Current Shear Design Equations for HSRC Beams

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Experimental research on the shear capacity of HSRC (High Strength Reinforced Concrete beams is relatively very limited as compared to the NSRC (Normal Strength Reinforced Concrete beams. Most of the Building Codes determine the shear strength of HSRC with the help of empirical equations based on experimental work of NSRC beams and hence these equations are generally regarded as un-conservative for HSRC beams particularly at low level of longitudinal reinforcement. In this paper, 42 beams have been tested in two sets, such that in 21 beams no transverse reinforcement has been used, whereas in the remaining 21 beams, minimum transverse reinforcement has been used as per ACI-318 (American Concrete Institute provisions. Two values of compressive strength 52 and 61 MPa, three values of longitudinal steel ratio and seven values of shear span to depth ratio have been have been used. The beams were tested under concentrated load at the mid span. The results are compared with the equations proposed by different international building codes like ACI, AASHTO LRFD, EC (Euro Code, Canadian Code and Japanese Code for shear strength of HSRC beams.From comparison, it has been observed that some codes are less conservative for shear design of HSRC beams and further research is required to rationalize these equations.

    This report assesses current public domain cyber security practices with respect to cyber indications and warnings. It describes cybersecurity industry and government activities, including cybersecurity tools, methods, practices, and international and government-wide initiatives known to be impacting current practice. Of particular note are the U.S. Government's Trusted Internet Connection (TIC) and 'Einstein' programs, which are serving to consolidate the Government's internet access points and to provide some capability to monitor and mitigate cyber attacks. Next, this report catalogs activities undertaken by various industry and government entities. In addition, it assesses the benchmarks of HPC capability and other HPC attributes that may lend themselves to assist in the solution of this problem. This report draws few conclusions, as it is intended to assess current practice in preparation for future work, however, no explicit references to HPC usage for the purpose of analyzing cyber infrastructure in near-real-time were found in the current practice. This report and a related SAND2010-4766 National Cyber Defense High Performance Computing and Analysis: Concepts, Planning and Roadmap report are intended to provoke discussion throughout a broad audience about developing a cohesive HPC centric solution to wide-area cybersecurity problems.

    To (1) describe characteristics of current interventions to improve hand function in young children with Cerebral Palsy (CP), and explore factors associated with (2) increased likelihood of hand and ADL training and (3) child benefits of training. A cross-sectional design was used with parent-reported data and data from the Norwegian CP Follow-up Program (CPOP). A total of 102 children (53% of the cohort of newly recruited children in the CPOP, mean age: 30.3 months, SD: 12.1) were included. Hand function was classified according to the Mini-Manual Ability Classification System (Mini-MACS). Data were analyzed with descriptive statistics, cross-tables and direct multiple logistic regressions. The majority of the children performed training of hand skills and ADL. Parents reported high amounts of training, and training was commonly integrated in everyday activities. Both parents (OR = 5.6, p hand training for children at Mini-MACS levels II-III compared to level I. Parents reported larger child benefits when training was organized as a combination of training sessions and practice within everyday activities (OR = 7.090, p = .011). Parents reported that the children's everyday activities were utilized as opportunities for training, hence describing the intensity of therapy merely by counting minutes or number of sessions seems insufficient.

  6. [Patient-reported clinical trial endpoints--the current state of affairs in research and practice].

    Kohlmann, Thomas

    2010-01-01

    Patient-reported outcomes are increasingly considered as endpoints for clinical studies. Instruments for measuring patient-reported outcomes range from simple assessments of discrete symptoms or signs to complex measures addressing multidimensional constructs such as health-related quality of life. While generic measures are designed to be applicable across a wide range of clinical conditions, disease- or population-specific instruments address health problems which are relevant for a particular disease or target group. Patient-reported outcomes can provide supplementary information from the patient's perspective when clinical endpoints are the primary focus of a study. As predictors and mediators of clinical outcomes they may contribute to the understanding of how patients benefit from treatment. They are included as primary endpoints when treatment effects comprise subjective phenomena such as pain, fatigue or psychological well-being. Current research activities in the field of patient-reported outcomes include the development of new (disease-specific) instruments, head-to-head comparisons of psychometric properties of measures, analysis of the context-dependence of results, and application of patient-reported outcomes in clinical practice.

    2014-01-01

    For several decades, Multidisciplinary Design Optimization (MDO) has served an important role in aerospace engineering by incorporating physics based disciplinary models into integrated system or sub-system models for use in research, development, (R&D) and design. This paper examines MDO's role in facilitating the integration of the researchers from different single disciplines during R&D and early design of large-scale complex engineered systems (LaCES) such as aerospace systems. The findings in this paper are summarized from a larger study on interdisciplinary practices and perspectives that included considerable empirical data from surveys, interviews, and ethnography. The synthesized findings were derived by integrating the data with theories from organization science and engineering. The over-arching finding is that issues related to cognition, organization, and social interrelations mostly dominate interactions across disciplines. Engineering issues, such as the integration of hardware or physics-based models, are not as significant. Correspondingly, the data showed that MDO is not the primary integrator of researchers working across disciplines during R&D and early design of LaCES. Cognitive focus such as analysis versus design, organizational challenges such as incentives, and social opportunities such as personal networks often drove the human interactive practices among researchers from different disciplines. Facilitation of the inherent confusion, argument, and learning in crossdisciplinary research was identified as one of several needed elements of enabling successful research across disciplines.

    This book presents a series of high performance product design (PD) and development best practices that can create or improve product development organization. In contrast to other books that focus only on Toyota or other individual companies applying lean IPD, this book explains the lean philosophy more broadly and includes discussions of systems engineering, design for X (DFX), agile development, integrated product development, and project management. The “Lean Journey” proposed here takes a value-centric approach, where the lean principles are applied to PD to allow the tools and methods selected to emerge from observation of the individual characteristics of each enterprise. This means that understanding lean product development (LPD) is not about knowing which tools are available but knowing how to apply the philosophy. The book comes with an accompanying manual with problems and solutions available on Springer Extras.

    2014-12-01

    Full Text Available The purpose of this paper is to synthesize current practices and procedures on the prevention of backing fatalities in highway work zones. First, general work zone safety hazards are reviewed, particularly blind areas are identified. Second, engineering controls currently in use are examined and explained to help understand what steps can be taken to prevent future backing fatalities. Third, administrative controls (including signalers, drivers, and workers-on-foot training are also discussed. Fourth, existing technology controls are reviewed for use in aiding equipment operators in identifying when pedestrian personnel are in dangerous areas around their equipment (i.e., back-up camera, radar. Fifth, recommendations are made based on the comprehensive review of the backover fatality prevention techniques in construction work zones and the conducted testing results of several commercially available systems. Recommendations on engineering and technology controls are discussed, with detailed information such as improving internal traffic control plans, and integrating technology with traffic control plans. Information and drawings are provided to illustrate how to design work zones, and the internal traffic flow diagrams are created using the integrated technology available, and site specific characteristics. The drawings represent examples of using different types of technology, in different scenarios using the proper legend, as well as using the proper general and technology notes to help explain the traffic control plan, ensuring that full comprehension is made. Recommendations on administrative controls are also given such as how to conduct safety meetings, electing safety officers, how to set regulations and guidelines for workers, and how to handle training. Training should be used as a backover fatality prevention method for pedestrian workers, flaggers, spotters, and equipment operators. Finally, a summary and discussion of future research

    Patrícia do Carmo Silva Parreira

    2014-03-01

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

    The research determined to what extent best practices are being followed by freely available online modules aimed at teaching critical thinking and evidence-based practices (EBPs) in health sciences fields. In phase I, an evaluation rubric was created after reviewing the literature. Individual rubric questions were assigned point values and grouped into sections, and the sections weighted. Phase II involved searching Internet platforms to locate online EBP modules, which were screened to determine if they met predetermined criteria for inclusion. Phase III comprised a first evaluation, in which two authors assessed each module, followed by a second evaluation of the top-scoring modules by five representatives from different health sciences units. The rubric's 28 questions were categorized into 4 sections: content, design, interactivity, and usability. After retrieving 170 online modules and closely screening 91, 42 were in the first evaluation and 8 modules were in the second evaluation. Modules in the first evaluation earned, on average, 59% of available points; modules in the second earned an average of 68%. Both evaluations had a moderate level of inter-rater reliability. The rubric was effective and reliable in evaluating the modules. Most modules followed best practices for content and usability but not for design and interactivity. By systematically collecting and evaluating instructional modules, the authors found many potentially useful elements for module creation. Also, by reviewing the limitations of the evaluated modules, the authors were able to anticipate and plan ways to overcome potential issues in module design.

    Approaches to diagnosis and treatment of growth hormone deficiency (GHD) in children vary among countries and even among centers in the same country. This survey, aiming to facilitate the process of preparing the new consensus on GHD by the Turkish Pediatric Endocrinology and Diabetes Society, was designed to evaluate the current practices in diagnosis and treatment of GHD in different centers in Turkey. A questionnaire covering relevant items for diagnosis and treatment of GHD was sent out to all pediatric endocrinology centers. Twenty-four centers returned the questionnaire. The most frequently used GH stimulation test was L-dopa, followed by clonidine. Eighteen centers used a GH cut-off value of 10 ng/mL for the diagnosis of GHD; this value was 7 ng/mL in 4 centers and 5 ng/mL in 2 centers. The most frequently used assay was immunochemiluminescence for determination of GH, insulin-like growth factor-1 and insulin-like growth factor binding protein-3 concentrations. Sex steroid priming in both sexes was used by 19 centers. The most frequently used starting dose of recombinant human GH (rhGH) in prepubertal children was 0.025-0.030 mg/kg/day and 0.030-0.035 mg/kg/day in pubertal children. Growth velocity was used in the evaluation for growth response to rhGH therapy in all centers. Anthropometric measurements of patients every 3-6 months, fasting blood glucose, bone age and thyroid panel evaluation were used by all centers at follow-up. Main indications for cessation of therapy were decreased height velocity and advanced bone age. Fourteen centers used combined treatment (rhGH and gonadotropin-releasing analogues) to increase final height. Although conformity was found among centers in Turkey in current practice, it is very important to update guideline statements and to modify, if needed, the approach to GHD over time in accordance with new evidence-based clinical studies.

    Subject material concerning Deoxyribose Nucleic Acid (DNA) structure in the format of creativity-driven laboratory practice offers meaningful learning experience to the students. Therefore, a laboratory practice in which utilizes simple procedures and easy-safe-affordable household materials should be promoted to students to develop their creativity. This study aimed to examine whether designing and conducting DNA extraction with household materials could foster students' creative thinking. We also described how this laboratory practice affected students' knowledge and views. A total of 47 students participated in this study. These students were grouped and asked to utilize available household materials and modify procedures using hands-on worksheet. Result showed that this approach encouraged creative thinking as well as improved subject-related knowledge. Students also demonstrated positive views about content knowledge, social skills, and creative thinking skills. This study implies that extracting DNA with household materials is able to develop content knowledge, social skills, and creative thinking of the students. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(3):216-225, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

    2013-12-01

    Mixed methods research offers powerful tools for investigating complex processes and systems in health and health care. This article describes integration principles and practices at three levels in mixed methods research and provides illustrative examples. Integration at the study design level occurs through three basic mixed method designs-exploratory sequential, explanatory sequential, and convergent-and through four advanced frameworks-multistage, intervention, case study, and participatory. Integration at the methods level occurs through four approaches. In connecting, one database links to the other through sampling. With building, one database informs the data collection approach of the other. When merging, the two databases are brought together for analysis. With embedding, data collection and analysis link at multiple points. Integration at the interpretation and reporting level occurs through narrative, data transformation, and joint display. The fit of integration describes the extent the qualitative and quantitative findings cohere. Understanding these principles and practices of integration can help health services researchers leverage the strengths of mixed methods. © Health Research and Educational Trust.

    Rivard, Jillian Rowback; Schreiber Compo, Nadja

    2017-05-01

    In child sexual abuse investigations, forensic interviewers within the Child Advocacy Center (CAC) model serve as neutral fact-finders for a team of professionals tasked with investigating and intervening in cases of alleged child sexual abuse. Although empirical evidence has led to the development of best-practice techniques and protocols, there is currently no universally adopted protocol in the field. The present research gathered detailed information from a national sample of real-world child forensic interviewers about their training and current practices, with a specific focus on assessing the information interviewers typically review prior to conducting child forensic interviews. Most notably, the survey revealed a lack of uniformity in interviewing protocols adopted and pre-interview preparation practices. Although rare, some interviewers reported using an allegation-blind interviewing approach, highlighting the need for future research on this and other under-studied techniques.

    2015-01-01

    Background Feed-thickening for infants in the Neonatal Intensive Care Unit (NICU) is performed due to concerns of dysphagia and gastroesophageal reflux disease (GERD). No standards currently exist regarding feed-thickening prescriptions and practices and this results in variable and potentially unsafe feeding approaches. Methods Electronic surveys were sent to neonatal feeding therapists and providers in order to determine the prescriptions and practices currently being used for feed-thickening in the NICU. Results A total of 313 responses were collected. Results revealed the majority of providers use thickened feeds for concerns of dysphagia or GERD with some reporting they thicken expressed breast milk. Variability of thickening prescriptions was noted regarding consistencies, thickening agents, and recipes used. Reported approaches for measuring, mixing, and warming thickened feeds varied. Conclusion Variability was noted in the feed-thickening prescriptions and practices performed in the NICU. Further research and standardization are required to develop thickening guidelines.

    2014-08-15

    This paper describes HFE program development project conducted at a Finnish power company Fortum. The aim of developing a formal HFE program was to improve integration of human factors issues in design of technical systems and to systematically document the HFE process of the company. As Fortum has a long tradition of designing control room solutions, the starting point of the HFE program development was the existing own design practices. On the other hand, the aim was to create a program which would comply with international guidelines such as NUREG-0711. The program development was conducted by tracing the HFE design practices in an on-going I and C modernization project. This empirical work was carried out by interviews of designers and other HFE key stake holders. After the explication of the current practices, the gaps, overlaps and differences in relation to the international standards and guidelines were identified. Based on an analysis of current practices and guidelines and standards a new HFE process model was created. The design process model can be followed in modifications which concern systems with human user interfaces of any kind. The model consists of five separate phases which comply with the general engineering design process model utilized at the company. The HFE program is intended to be both a practical guide on how to take human factors issues into consideration in the design of NPP systems and also a tool for the management of HFE activities.

    With today's tightening budgets computer applications must provide "true" long-term benefit to the company. Businesses are spending large portions of their budgets "Re- Engineering" old systems to take advantage of "new" technology. But what they are really getting is simply a new interface implementing the same incomplete or poor defined requirements as before. "True" benefit can only be gained if sound analysis and design practices are used. WHAT data and processes are required of a system is not the same as HOW the system will be implemented within a company. It is the System Analyst's responsibility to understand the difference between these two concepts. The paper discusses some simple techniques to be used during the Analysis and Design phases of projects, as well as the information gathered and recorded in each phase and how it is transformed between these phases. The paper also covers production application generated using Oracle Designer. Applying these techniques to "real world" problems, the applications will meet the needs for today's business and adapt easily to ever-changing business environments.

  18. Recognized focused practice: Does sub-specialty designation offer value to the neurosurgeon?

    Directory of Open Access Journals (Sweden)

    Maya A Babu

    Full Text Available Vehicles for life-long assessment such as Maintenance of Certification tend to focus on generalist neurosurgical knowledge. However, as neurosurgeons advance in their careers, they tend to narrow their practice and increase volumes in certain specific types of operations. Failing to test the type of procedures most relevant to the practitioner is a lost opportunity to improve the knowledge and practice of the individual neurosurgeon. In this study, we assess the neurosurgical community's appetite for designations of board-recognized Recognized Focused Practice (RFP. We administered a validated, online, confidential survey to 4,899 neurosurgeons (2,435 American Board of Neurological Surgery (ABNS Diplomates participating in MOC, 1,440 Diplomates certified prior to 1999 (grandfathered, and 1,024 retired Diplomates. We received 1,449 responses overall (30% response rate. A plurality of respondents were in practice 11-15 years (18.5%, in private practice (40% and participate in MOC (61%. 49% of respondents felt that a RFP designation would not be helpful. For the 30% who felt that RFP would be helpful, 61.3% felt that it would support recognition by their hospital or practice, it would motivate them to stay current on medical knowledge (53.4%, or it would help attract patients (46.4%;. The most popular suggestions for RFP were Spine (56.2%, Cerebrovascular (62.9%, Pediatrics (64.1%, and Functional/Stereotactic (52%. A plurality of neurosurgeons (35.7% felt that RFP should recognize neurosurgeons with accredited and non-accredited fellowship experience and sub-specialty experience. Ultimately, Recognized Focused Practice may provide value to individual neurosurgeons, but the neurosurgical community shows tepid interest for pursuing this designation.

    2016-01-01

    To investigate current practices, barriers, and training needs for the promotion of physical activity (PA) in physiotherapy practices in eastern Nigeria. A total of 141 fully licensed physiotherapists in southeast Nigeria were invited to participate in a cross-sectional survey consisting of 23 questions in five key sections, focusing mainly on risk-factor management practices of physiotherapists. A total of 103 questionnaires were returned. Respondents ranged in age from 25 to 54 years and reported a mean of 11 (SD 10) years of clinical experience. Respondents reported that they regularly assess and advise their clients on PA but rarely give written prescriptions. Although they are confident in assessing and advising their clients on PA and consider including PA intervention as a priority in daily practice, lack of time and lack of access to materials were reported as barriers to effective PA intervention. Findings showed the potential for physiotherapists to address physical inactivity and highlighted several barriers. Strategies are needed to improve contact time with clients and make material promoting PA available to practising physiotherapists.

    2014-10-01

    Full Text Available This article explores the tangible and intangible dimensions of the relationship between street furniture, public space and its user. This relationship is discussed through a reflection on the concepts and key features in the development of interdisciplinary street furniture design projects. It is addressed the importance of street furniture elements in the valorisation and perception of the quality of public space, and the various dimensions underlying these artefacts. It is also discussed the concept of interdisciplinarity, integrating it within the view of co-design and how the new forms of public participation are changing the practice of design. It was intended to understand the full innovation potential of an interdisciplinary approach to street furniture design and the implications of that action.

    The World Wide Web has led to the rapid growth of medical information and continuing medical educational offerings. Ease of access and availability at any time are advantages of the World Wide Web. Existing physician-education sites have often been designed and developed without systematic application of evidence and cognitive-educational theories; little rigorous evaluation has been conducted to determine which design factors are most effective in facilitating improvements in physician performance and patient-health outcomes that might occur as a result of physician participation in Web-based education. Theory and evidence-based Web design principles include the use of: needs assessment, multimodal strategies, interactivity, clinical cases, tailoring, credible evidence-based content, audit and feedback, and patient-education materials. Ease of use and design to support the lowest common technology denominator are also important. Using these principles, design and develop a Web site including multimodal strategies for improving chlamydial-screening rates among primary care physicians. We used office-practice data in needs assessment and as an audit/feedback tool. In the intervention introduced in 4 phases over 11 months, we provided a series of interactive, tailored, case vignettes with feedback on peer answers. We included a quality-improvement toolbox including clinical practice guidelines and printable patient education materials. In the formative evaluation of the first 2 chlamydia modules, data regarding the recruitment, enrollment, participation, and reminders have been examined. Preliminary evaluation data from a randomized, controlled trial has tested the effectiveness of this intervention in improving chlamydia screening rates with a significant increase in intervention physicians' chlamydia knowledge, attitude, and skills compared to those of a control group. The application of theory in the development and evaluation of a Web-based continuing medical

    Bioremediation is potentially a cost-effective and environmentally friendly approach for clean-up of hazardous chemicals from polluted geoenvironments, especially toxic organic compounds, like perchloroethene (PCE) and trichloroethene (TCE) from low-permeability strata at depths. The use of Hydrogen Release Compound (HRC) or Oxygen Release Compound (ORC) is a common practice to accelerate anaerobic bioremediation or aerobic bioremediation, depending on the chemical forms of pollutants to be treated. An effective remediation, however, needs effective mixing of, and interaction between the bacteria, target compound(s), injected HRC or ORC as well as other substances if necessary. An understanding of migration behavior of dissolved hydrogen and dissolved oxygen in geological formations is, therefore, an important research subject for predicting potential areas of remediation during acceptable time periods. In this study, 3 practical solutions to the plane source, point source and line source diffusions which correspond to the semi-infinite, spherical and cylindrical models were derived and used to discuss the diffusive transport through low permeability geological media. A series of parameter studies using feasible values for the diffusion coefficient obtained from both literature survey and independent laboratory experiments were performed. Expected areas of hydrogen or oxygen migration were assumed to be from several tens of centimeters to a few meters with consideration of practical pollution problems, and acceptable remediation time periods were considered to be from several months to the maximum of 10-15 years. The results obtained from this study illustrated that transport of chemical substances, like dissolved hydrogen or oxygen used for accelerated bioremediation, due to diffusion is very sensitive to the magnitude of diffusion coefficient. The area of migration due to natural diffusion could be very limited. To effectively design and perform an accelerated

    Full Text Available The interactive technical electronic book, TechEBook, currently under development at the University of Central Florida (UCF, provides a useful tool for engineers and scientists through unique features compared to the most used traditional electrical circuit textbooks available in the market. TechEBook has comprised the two worlds of classical circuit books and an interactive operating platform such as iPads, laptops and desktops utilizing Java Virtual Machine operator. The TechEBook provides an interactive applets screen that holds many modules, in which each had a specific application in the self learning process. This paper describes two of the interactive techniques in the TechEBook known as, Practical Relevance Modules (PRM and Design Modules (DM. The Practical Relevance Module will assist the readers to learn electrical circuit analysis and to understand the practical application of the electrical network theory through solving real world examples and problems. The Design Module will help students design real-life problems. These modules will be displayed after each section in the TechEBook for the user to relate his/her understanding with the outside world, which introduces the term me-applying and me-designing, as a comprehensive full experience for self or individualized education. The main emphasis of this paper is the PRM while the DM will be discussed in brief. A practical example of applying the PRM and DM features is discussed as part of a basic electrical engineering course currently given at UCF and results show improved student performances in learning materials in Electrical Circuits. In the future, such modules can be redesigned to become highly interactive with illustrated animations.

The key goal is to gauge the extent to which this 2012 statement is reflected in current practices among the sellers and buyers of translation services between Japanese and English. In this paper, which describes the first part of the study, the focus is on the practices of sellers of translation services between Japanese and English: specifically, professional freelance translators. Twenty-four professional freelance translators completed an online questionnaire. The results of this questionnaire, first, suggest that current practices among sellers of translation services between Japanese and English are consistent with the Japan Translation Federation’s 2012 statement and, second, broadly support secondary literature on L1 translation (translation into the first language and L2 translation (translation into the second language. Whilst this is only a snapshot of current practices among sellers of translation services between Japanese and English, the overall results are informative. In the second, follow-up part of the study the focus will be on the current practices of buyers of translation services between Japanese and English.

    Roof-harvested rainwater (RHRW) is an important alternative source of water that many island communities can use for drinking and other domestic purposes when groundwater and/or surface water sources are contaminated, limited, or simply not available. The aim of this pilot-scale study was to investigate current RHRW practices in American Samoa (AS) and to evaluate and compare the quality of water from common potable water sources including RHRW stored in tanks, untreated stream water, untreated municipal well water, and treated municipal tap water samples. Samples were analyzed using culture-based methods, quantitative polymerase chain reaction (qPCR), and 16S amplicon sequencing-based methods. Based on indicator bacteria (total coliform and Escherichia coli) concentrations, the quality of RHRW was slightly lower than well and chlorinated tap water but exceeded that of untreated stream water. Although no Giardia or Leptospira spp. were detected in any of the RHRW samples, 86% of the samples were positive for Cryptosporidium spp. All stream water samples tested positive for Cryptosporidium spp. Opportunistic pathogens (Pseudomonas aeruginosa and Mycobacterium intracellulare) were also detected in the RHRW samples (71 and 21% positive samples, respectively). Several potentially pathogenic genera of bacteria were also detected in RHRW by amplicon sequencing. Each RHRW system was characterized by distinct microbial communities, 77% of operational taxonomic units (OTUs) were detected only in a single tank, and no OTU was shared by all the tanks. Risk of water-borne illness increased in the following order: chlorinated tap water/well water water. Frequent detection of opportunistic pathogens indicates that RHRW should be treated before use. Stakeholder education on RHRW system design options as well as on importance of regular cleaning and proper management techniques could improve the quality of the RHRW in AS.

    The National Renewable Energy Laboratory (NREL) has undertaken a complete review and update of the process design and economic model for the biomass-to-ethanol enzymatic based process. The process design includes the core technologies being researched by the U.S. Department of Energy (DOE): prehydrolysis, simultaneous saccharification and co-fermentation, and cellulase enzyme production. In addition, all ancillary areas--feed handling, product recovery and purification, wastewater treatment lignin burner and boiler--turbogenerator, and utilities--are included. NREL engaged Delta-T Corporation to assist in the process design evaluation, equipment costing, and overall plant integration. The process design and costing for the lignin burner and boiler turbogenerator has been reviewed by Reaction Engineering Inc. and the wastewater treatment by Merrick and Company. An overview of both reviews is included here. The purpose of this update was to ensure that the process design and equipment costs were reasonable and consistent with good engineering practice for plants of this type using available technical data. This work has resulted in an economic model that can be used to predict the cost of producing ethanol from cellulosic biomass using this technology if a plant were to be built in the next few years. The model was also extended using technology improvements that are expected to be developed based on the current DOE research plan. Future process designs and cost estimates are given for the years 2005, 2010, and 2015.

    The aim of this article is to report on current provider evidence-based assessment and treatment practices for older adults with cancer in community-based hospice settings. Using the Cancer Pain Practices Index (CPPI), a tool developed by the researchers to measure evidence-based pain management practices, patients received an average of 32% of the those key evidence-based practices (EBPs) that were applicable to their situation. When examining individual practices, the majority of patients had their pain assessed at admission using a valid pain scale (69.7%) and had primary components of a comprehensive assessment completed at admission (52.7%); most patients with admission reports of pain had an order for pain medication (83.5%). However, data revealed a number of practice gaps including: additional components of a comprehensive assessment completed within 48 hours of admission (0%); review of the Pain Treatment Plan at each reassessment (35.7%); reassessment of moderate or greater pain (5.3%); consecutive pain reports of 5 or greater followed by pain medication increases (15.8%); monitoring of analgesic- induced side effects (19.3%); initiation of a bowel regimen for patients with an opioid order (32.3%); and documentation of both non-pharmacological therapies (22.5%) and written pain management plans (0.6%). Findings highlight positive EBPs and areas for improving the translation of EBPs into practice. Data suggest that cancer pain is not being documented as consistently assessed, reassessed or treated in a manner consistent with current EBP recommendations for older adults with cancer in community-based hospices.

    Full Text Available The syllabus is an essential factor in the achievement of communicative competence in second language teaching. Various proposals for syllabus design have been made, ranging from product to process syllabuses. Their theoretical bases and the practical constraints which influence them are discussed. The product syllabus is a formal statement of the end product, and has been criticized mainly because it cannot account for communicative competence in the syllabus design itself and because it may encourage a step-by-step teaching procedure. The process syllabus attempts to address learning procedures and is concerned with learning experiences and the negotiation of meaning. This approach is also not without its critics. But practical factors such as administrative requirements, teacher capacity and learner differences constrain the syllabus design. It is concluded that a process syllabus which specifies the classroom activities in much more detail than has been the case so far, and which contains product elements to accommodate some of the constraints, is likely to realize the aim of communicative competence.

    The aim of this study was to determine current delirium practices in the intensive care unit (ICU) setting and evaluate awareness and adoption of the 2013 Pain, Agitation, and Delirium (PAD) guidelines with emphasis on delirium management. A large-scale, multidisciplinary, online survey was administered to physician, pharmacist, nurse, and mid-level practitioner members of the Society of Critical Care Medicine (SCCM) between September 2014 and October 2014. A total of 635 respondents completed the survey. Nonpharmacologic interventions such as early mobilization were used in most ICUs (83%) for prevention of delirium. A majority of respondents (97%) reported using pharmacologic agents to treat hyperactive delirium. Ninety percent of the respondents answered that they were aware of the 2013 PAD guidelines, and 75% of respondents felt that their delirium practices have been changed as a result of the new guidelines. In addition, logistic regression analysis of this study showed that respondents who use delirium screening tools were twice more likely to be fully aware of key components of the updated guidelines (odds ratio [OR] = 2.07, 95% confidence interval [CI] = 1.20-3.60). Most critical care practitioners are fully aware and knowledgeable of key recommendations in the new guidelines and have changed their delirium practices accordingly.

    Extent of and challenges to implementation of the Centers for Disease Control and Prevention (CDC) 2006 recommendation for routine HIV testing have not been reviewed specifically within tuberculosis (TB) care settings. To determine current adherence to the CDC's HIV testing recommendations in TB care settings and identify barriers. An online survey was designed and distributed via Survey Monkey. The 2011 National TB Conference attendees, National TB Nurse Controllers, and the CDC's TB-educate mailing list were invited to participate via e-mail. A total of 153 respondents from US states: 30 physicians, 91 nurses, 19 public health practitioners, and 13 other. Perceived importance of HIV testing, current HIV testing practices, perceived barriers to HIV testing, and understanding of state HIV testing laws. One hundred forty-one of 153 (92.2%) reported that patients with TB disease were "always" or "almost always" HIV tested; 65 of 153 (42.5%) reported the same for patients with latent TB infection (LTBI). Among those not routinely testing LTBI patients, "patient refusal of test" (53/88; 60.2%), "cost" (41/88; 46.6%), and "prevalence too low to justify" (33/88; 37.5%) were the most commonly identified barriers to opt-out testing. Forty-seven of 59 providers (79.7%) who reported that their state required written consent for HIV testing had incorrect knowledge regarding HIV testing legislation. Rates of HIV testing are high for patients with TB disease, but fewer than half of providers' care settings routinely test LTBI patients. Knowledge of HIV status is required to appropriately interpret TST results and make decisions regarding treatment in TB infection, since HIV coinfection increases risk of progression to active TB. Lack of HIV testing in LTBI patients represents a missed opportunity to prevent TB disease and its resultant morbidity and mortality. In addition, incorrect knowledge regarding testing legislation was a common problem among our TB providers. Further

    Small practices often lack the human, financial and technical resources to make necessary practice improvements and infrastructure investments in order to achieve sustainable change that promotes quality and efficiency. To report on an effort to assist small primary care practices in improving quality of care and efficiency of practice management to meet the needs of patients, improve physician satisfaction and enhance the ability of these small practices to survive. We report on an intervention design and the reflections of the implementers on what they learned and what went well or poorly during implementation. Results of the intervention are reported separately (in Quality in Primary Care). Thirty practices underwent the entire intervention. The practices were selected on the basis of practice size, diversity in patient factors, apparent dedication to making practice improvements and geographic location. The main components of the intervention were two site visits to the participating practices by Center for Practice Innovation (CPI); now known as the Centre for Practice Improvement and Innovation, team members. The CPI team provided ongoing advice and support in focus areas selected by practices after initial site visit and assessment. A customised session focusing on the practice report and on helping practices to think about which areas they wished to improve was more effective in engaging practices than didactic presentation. Quality and practice management improvements were observed in information posting, patient education, staff communication and patient safety practices. Having a strong physician champion and a strong office manager determined to make quality improvement changes were important elements for successful change. In addition, practices with greater stability of staff and strong finances were more likely to meet project goals. Small practices today are facing a range of important challenges. The CPI sought to provide successful guidance to

    A questionnaire survey of physiotherapists treating low back pain. To investigate current clinical practice in the physiotherapeutic management of low back pain in Northern Ireland. Physiotherapists play an important role in the management of low back pain. However, there is relatively limited evidence about physiotherapy or about current physiotherapeutic management of low back pain. This survey aimed to establish current practice in this area. Two sets of questionnaires were completed by physiotherapists during the period 1996-1997: one in relation to their professional profile, and subsequently a questionnaire for each patient referred by physicians to physiotherapy departments in the (government-funded) National Health Service in Northern Ireland. Physiotherapists (n = 157) recorded data for 1062 patients treated for low back pain in 35 outpatient centers across Northern Ireland. Of the patients treated, 70% had a duration of current episode more than 6 weeks; 26% of patients had previously received physiotherapy for low back pain. Physiotherapy treatment most commonly involved advice (89% of patients), McKenzie treatment (70%), Maitland mobilizations (42%), and interferential therapy (30.3%). Physiotherapists typically treated subacute and chronic patients, principally using some types of manual techniques and advice, in keeping with current guidelines. However, high levels of the use of electrotherapy, and only limited use of manipulation, indicates the importance of further research to establish optimum management for this group of patients.

  1. The Development of Perioperative Practices for Liver Transplantation: Advances and Current Trends

    2008-09-01

    Full Text Available Transplantation is a young medical specialty that has grown rapidly over the past 50 years. Anesthesiologists, surgeons and hepatologists are all essential partners in the process of determining patient outcome. Each specialty has made landmark improvements in patient outcome. However, there is still variability in practice patterns in each of the 3 major specialties. This review will use a historic perspective to explore the unique forces that shaped specific transplant practices and those that gave rise to differences in perioperative practices. Anesthesiologists and surgeons have made significant improvements in the management of blood loss, and coagulation monitoring and intervention. This has improved operative survival and early patient outcome. Perioperative survival has improved despite a worldwide shortage of donor organs and a trend to transplant sicker patients. A smaller pool of donor organs is required to meet the needs of an expanding waiting list. The innovations to reduce deaths on the transplant wait list are reviewed along with their impact on overall patient outcome. The evolving organ shortage is the pinnacle point in shaping future transplant practices. Currently, institutional-specific practices may be reinforced by the informal “tutorship” that is used to train physicians and by the resources available at each site of practice. However, there is evidence that specific intraoperative practices such as the use of a low central venous pressure, selection of vasopressors and certain surgical techniques can modify patient outcome. Further investigation is needed to determine whether the good or the bad associated with each practice prevails and in what unique circumstance.

    2015-06-01

    The aging of the US population and shortage of geriatric psychiatrists mean that all medical students must be prepared to evaluate psychiatric symptoms in older patients. The authors sought to describe current geriatric psychiatry teaching practices during the psychiatry clerkship. Psychiatry clerkship directors at 110 American medical schools were surveyed about didactic and clinical experiences of geriatric psychiatry. Sixty-two (56 %) of programs responded. One fifth of programs lacked specific instruction in geriatric psychiatry. Programs were more likely to include instruction on dementia than late-life depression. Increased geriatric psychiatry educational offerings were associated with the following: number of geriatric psychiatrists on faculty, presence of a geriatric psychiatrist on the medical education committee, and inclusion of geriatric psychiatry specific items in clerkship learning objectives. Current practices in some clerkships are inadequate to prepare medical students to care for older patients with psychiatric symptoms.

    Background Medication nonadherence is a major problem in chronic kidney failure patients undergoing dialysis. Pharmacists play a vital role in improving medication-related patient outcomes, reducing drug-related problems, and improving medication adherence. However, little is known about how pharmacists assess medication adherence in dialysis patients. Objective To measure pharmacists' perceptions, current practices, and barriers to assessing adherence in dialysis patients. Setting Australian renal-specialised pharmacists. Method An online survey was conducted between March and May 2016. Survey included five psychometric scales measuring perceived prevalence, contributors, effective methods, barriers, and confidence to assess adherence on a 10-point Likert scale (1 = strongly disagree; 10 = strongly agree). Current practices were identified using a 4-point graded response (1 = do not practice; 4 = practice for all). Perception scores, scale reliability, and responses to current practices questionnaire. Results 41 pharmacists completed the survey (response rate, 91.1%). The majority (91.9%, n = 34; median = 8.0) agreed patients were nonadherent to medication. Time constraints (43.8%, n = 14) and hospital support (31.3%, n = 10) were perceived as barriers to assessment. Objective blood monitoring was frequently used to determine nonadherence (57.1%, n = 16), whereas subjective interviews were rarely conducted (27.6%, n = 8). Though all pharmacists support the presence of dedicated pharmacist for assessing adherence (100.0%, n = 33), only 24.2% were actually performing this function. Conclusion Pharmacists were rarely assigned for adherence assessment in dialysis settings. Established self-report methods were under-utilised compared to objective methods. Future research should investigate the effectiveness of pharmacists' involvement in facilitating adherence promotion and early identification of medication-related issues in dialysis patients.

    1.1 This practice covers the use of conformable eddy-current sensors for nondestructive characterization of coatings without standardization on coated reference parts. It includes the following: (1) thickness measurement of a conductive coating on a conductive substrate, (2) detection and characterization of local regions of increased porosity of a conductive coating, and (3) measurement of thickness for nonconductive coatings on a conductive substrate or on a conductive coating. This practice includes only nonmagnetic coatings on either magnetic (μ ≠ μ0) or nonmagnetic (μ = μ0) substrates. This practice can also be used to measure the effective thickness of a process-affected zone (for example, shot peened layer for aluminum alloys, alpha case for titanium alloys). For specific types of coated parts, the user may need a more specific procedure tailored to a specific application.

Both standard ASME acceptance testing procedures and individualized plant performance testing procedures are reviewed. The instrumentation required for performance testing, along with its limitations, is cited. A review of digital computer uses is presented, including some examples of typical performance related logs used by a few utilities. Control functions that affect plant performance, such as steam temperature control, are discussed, and the potential impact of several of the above issues on economic dispatching is mentioned. It is concluded that there is no typical utility or common practice regarding performance improvement. Each utility has its own strategy, practice, and methods or lack thereof. Furthermore, knowledge of what other utilities are doing, successfully and unsuccessfully, is lacking. The recommendations stress better information dissemination, more quantitative evaluation of advanced concepts, and initiation of a few high priority research projects.

    To evaluate methods of performance assessment through an international literature review and a survey of current practice. Over the past two decades health care organizations have focussed on promoting high quality care in conjunction with retaining motivated staff. Cognisant of such initiatives, we sought to evaluate assessment methods for qualified staff according to their utility in the working environment. A systematic literature search was completed and each paper independently reviewed. All health care organizations in Northern Ireland submitted details of their performance assessments. Each was critically appraised using a utility index. Performance was not universally defined. A broad range of assessments were identified, each method had advantages and disadvantages. Although many lacked rigorous testing, areas of good practice were also noted. No single method is appropriate for assessing clinical performance. Rather, this study endorses proposals for a multi-method strategy to ensure that performance assessment demonstrates all attributes required for effective nursing and midwifery practice.

    This paper presents a current control design for switched reluctance motors (SRMs). The electric transfer characteristic of the motors is studied first. Their transfer function is brought out to be represented by a pure resistive component, which is not constant but varies depending on the motor current and speed. The current control design for SRMs follows the classical design technique used for dc machines, where the zero of PI controller cancels the pole of Ls+R. Because the transfer function of SRMs does not have any poles, an I controller is suitable for them. The integral gain should be adjusted in order to compensate the non-linearity, that is, the variation in the equivalent resistor of the SRMs' transfer function. The values of the integral gain are tuned and tabulated for the motor speed and current. Simulation and experiment demonstrate that the current and speed of the SRMs presents good responses without dependence on the motor speed and current.

    Use of medical thoracoscopy by respiratory physicians is increasing. This survey of experienced thoracoscopists was conducted to establish current practice of medical thoracoscopy and physicians' opinion of theoretical cases using 20 video clips. Results suggest an increasing trend towards day-case thoracoscopy but that caution is required when making diagnosis on macroscopic appearance: malignant and benign disease could only be differentiated in 59% of cases, and trapped lung is difficult to predict at thoracoscopy. © 2015 Asian Pacific Society of Respirology.

    3D digital graphics and representation have been a critical part in landscape architecture professional practice. However, few studies have been conducted to document how 3D digital graphics are currently being used. Some important questions are largely unknown. For example, who are the primary users of 3D digital graphics programs, and what are the most popular 3D software packages, and why. A better understanding of these questions is not only important to practitioners, but also to educato...

  11. Toward a more materialistic medicine: the value of authentic materialism within current and future medical practice.

    Leder, Drew; Krucoff, Mitchell W

    2011-09-01

    Modern medicine is often accused by diverse critics of being "too materialistic" and therefore insufficiently holistic and effective. Yet, this critique can be misleading, dependent upon the ambiguous meanings of "materialism." The term can refer to the prevalence of financial concerns in driving medical practice. Alternatively, it can refer to "mechanistic materialism," the patient viewed as a body-machine. In each case, this article shows that this represents not authentic "materialism" at play, but a focus upon high-level abstractions. "Bottom-line" financial or diagnostic numbers can distract practitioners from the embodied needs of sick patients. In this sense, medical practice is not materialist enough. Through a series of clinical examples, this article explores how an authentic materialism would look in current and future practice. The article examines the use of prayer/comfort shawls at the bedside; hospitals and nursing homes redesigned as enriched healing environments; and a paradigmatic medical device--the implantable cardioverter defibrillator--as it might be presented to patients, in contrast to current practice.

    Mallet injuries are common and usually treated conservatively. Various systematic reviews have found a lack of evidence regarding the best management, and it is unclear whether this uncertainty is reflected in current UK practice. An online survey was developed to determine the current practice for the conservative treatment of mallet injury among specialist hand clinicians in the UK, including physiotherapists, occupational therapists and surgeons. Clinician's views of study outcome selection were also explored to improve future trials. In total, 336 professionals completed the survey. Inconsistency in overall practice was observed in splint type choice, time to discharge to GP, and assessment of adherence. Greater consistency was observed for recommended duration of continuous immobilisation. Bony injuries were most commonly splinted for 6 weeks (n = 228, 78%) and soft tissue injuries for either 8 weeks (n = 172, 56%) or 6 weeks (n = 119, 39%). Post-immobilisation splinting was frequently recommended, but duration varied between 2 and 10 weeks. The outcome rated as most important by all clinicians was patient satisfaction. There is overall variation in the current UK conservative management of mallet injuries, and the development of a standardised, evidence-based protocol is required. Clinicians' opinions may be used to develop a core set of outcome measures, which will improve standardisation and comparability of future trials. Crown Copyright © 2017. Published by Elsevier Ltd.

    Smartphones are rapidly changing the way doctors capture and communicate clinical information, particularly in highly visual specialties such as dermatology. An understanding of how and why smartphones are currently used in clinical practice is critical in order to evaluate professional and legal risks, and to formulate policies that enable safe use of mobile technologies for the maximal benefit of practitioners and patients. Australian dermatologists and dermatology trainees were surveyed on their current practices relating to clinical smartphone use. Of the 105 respondents, 101 provided useable results. The data show clinical smartphone use is common and frequent, with more than 50% of respondents sending and receiving images on their smartphones at least weekly. Clinical photographs were usually sent via multimedia message or email and were commonly stored on smartphones (46%). Security measures adopted to protect data were limited. There was inadequate documentation of consent for transmission of photographs and advice provided. Only 22% of respondents were aware of clear policies in their workplace regarding smartphone use, and a majority desired further education on digital image management. Given the frequency of use and the degree of importance placed on the ability to send and receive clinical images, clinical smartphone use will persist and will likely increase over time. Current practices are insufficient to comply with professional and legal obligations, and increase practitioners' vulnerability to civil and disciplinary proceedings. Further education, realistic policies and adequate software resources are critical to ensure protection of patients, practitioners and the reputation of the dermatological profession. © 2017 The Australasian College of Dermatologists.

    Pelvic girdle pain (PGP) is frequently managed by physiotherapists. Little is known about current physiotherapy practice and beliefs in the management of PGP disorders. The primary aim of this study was to investigate current practice and beliefs in management of PGP among physiotherapists working in Norway and Australia. A secondary aim was to compare current practice with clinical guidelines. A questionnaire was developed and electronically distributed to physiotherapists in Norway (n = 65) and Australia (n = 77). Treatment and management were determined via responses to 2 case vignettes (during pregnancy, not related to pregnancy), with participants selecting their four primary preferences for treatment and management from a list of 33 possibilities. During pregnancy, 'education around instability' and 'soft tissue treatment' were selected amongst the most common interventions by physiotherapists in both countries. Norwegian physiotherapists selected 'pelvic floor exercises' more frequently, while Australian physiotherapists more commonly selected 'correcting functional impairments'. In the other case, common responses from both countries were 'hip strengthening in weight bearing' and 'correction of functional impairments'. Norwegian physiotherapists selected 'general physical exercise' and 'general education' more frequently, while Australian physiotherapists more commonly selected 'hip strengthening in non-weight bearing' and 'muscular relaxation of the abdominal wall/pelvic floor'. Beliefs about PGP were generally positive in both groups while knowledge of and adherence to clinical guidelines were limited. The findings provide direction for future research related to the management and treatment of PGP, and targets for education of physiotherapists working in this area. Copyright © 2014 Elsevier Ltd.

    2004-01-01

    An AIAA Special Project Report was recently produced by AIAA's Nuclear and Future Flight Propulsion Technical Committee and is currently in peer review. The Report provides recommended design practices for conceptual engineering studies of nuclear fusion space propulsion systems. Discussion and recommendations are made on key topics including design reference missions, degree of technological extrapolation and concomitant risk, thoroughness in calculating mass properties (nominal mass properties, weight-growth contingency and propellant margins, and specific impulse), and thoroughness in calculating power generation and usage (power-flow, power contingencies, specific power). The report represents a general consensus of the nuclear fusion space propulsion system conceptual design community and proposes 15 recommendations. This paper expands on the Report by providing specific examples illustrating how to apply each of the recommendations.

    Dendrimers and dendrons offer an excellent platform for developing novel drug delivery systems and medicines. The rational design and further development of these repetitively branched systems are restricted by difficulties in scalable synthesis and structural determination, which can be overcome by judicious use of molecular modelling and molecular simulations. A major difficulty to utilise in silico studies to design dendrimers lies in the laborious generation of their structures. Current modelling tools utilise automated assembly of simpler dendrimers or the inefficient manual assembly of monomer precursors to generate more complicated dendrimer structures. Herein we describe two novel graphical user interface toolkits written in Python that provide an improved degree of automation for rapid assembly of dendrimers and generation of their 2D and 3D structures. Our first toolkit uses the RDkit library, SMILES nomenclature of monomers and SMARTS reaction nomenclature to generate SMILES and mol files of dendrimers without 3D coordinates. These files are used for simple graphical representations and storing their structures in databases. The second toolkit assembles complex topology dendrimers from monomers to construct 3D dendrimer structures to be used as starting points for simulation using existing and widely available software and force fields. Both tools were validated for ease-of-use to prototype dendrimer structure and the second toolkit was especially relevant for dendrimers of high complexity and size.

    2015-01-01

    A new cryogenic dc current transformer (Cryo-DCCT) has recently been designed and assembled at CERN. The device, whose design is based on that of a high-accuracy 600 A market solution suitable for room temperature applications, is optimized for measuring currents of up to 80 kA and for operation at 4.2 K. The CryoDCCT has been conceived with the objective of preserving the metrological performance of the original commercial device in the new extended range of operation. For reducing the effect of interfering magnetic fields arising from test conditions, it incorporates ferromagnetic and MgB2 superconducting shields. In this paper, the design of the CryoDCCT and the results of the commissioning of the device at CERN are reported. The effectiveness of the current transducer is analysed and discussed. This new device will be used for measuring the secondary current of a 80 kA superconducting transformer feeding a sample of NbSn3 cable at the Facility for Research on Superconducting Cables (FRESCA) at CERN.

    Practice patterns and choice of technological instruments in PCNL are not always standardized. There are no previous reports on the PCNL practice tendencies and patterns in Latin America. The aim of the study is to describe the current practice patterns of PCNL among the members of the Mexican Society of Urology ("Sociedad Mexicana de Urologia"). Observational and descriptive study. A 9-item closed questionnaire on PCNL practice patterns was answered by members of the Mexican Society of Urology in a secure website hosted survey after e-mail invitation. A descriptive numerical and graphical analysis was performed. A total of 90 contestants were registered out of 492 potential participants. PCNL is performed by 80% of the participants, with an average of 16 procedures per year. Percutaneous tracts are commonly obtained by urologists on the same day of the procedure. Sequential and telescopic dilators are equally preferred over balloons. The pneumatic litotriptor is the most common choice and CT scan and X-ray are equally used as follow-up. The practice patterns of PCNL from Mexican urologists are different from other international reports. Influence of socio-economic circumstances is inferred.

    Rotator cuff disorders, including rotator cuff tears, are common and can be treated conservatively or surgically. Data suggest that the incidence of surgery to repair the rotator cuff is rising. Despite this rise, the most effective approach to postoperative rehabilitation, a critical component of the recovery process, is not well developed. The present study aimed to describe current practice in the UK in relation to rehabilitation following rotator cuff repair. An electronic survey was developed and disseminated to UK based physiotherapists and surgeons involved with rotator cuff repair. One hundred valid responses were received. Although there is a degree of variation, current practice for the majority of respondents consists of sling immobilization for 4 weeks to 6 weeks. During this time, passive movement would be commenced before active movement is introduced towards the end of this phase. Resisted exercise begins 7 weeks to 12 weeks postoperatively, alongside return to light work. A progressive resumption of function, including manual work and sport, is advised from approximately 13 weeks. In the context of the current literature, it might be suggested that the current approach to rehabilitation following rotator cuff repair for the majority of respondents is somewhat cautious and has not progressed for over a decade.

  20. Questioning current practice in brown bear, Ursus arctos, conservation in Europe that undervalues taxonomy

    2016-07-01

    The present paper highlights problems associated with the currently–accepted taxonomy of brown bear, Ursus arctos, and their consequences for conservation at the European level. The enormous morphological variability within Ursus arctos is not acknowledged in current taxonomy and conservation practice. Seven major clades are recognized in Ursus arctos by molecular researchers, and although Western Europe maintains most of the populations belonging to the relict Clade 1 brown bear lineage, no reference to this is made in current conservation policy. Furthermore, the tiny population of Apennine brown bears, characterized by unique skull morphology, is not even recognized as a distinct ESU (evolutionari significant unit) by current European legislation, nor is it included in the IUCN Red List. This may have serious consequences as brown bear conservation in Western Europe has been mainly based on restocking and reintroduction programs. (Author)

    The nature of Australian community pharmacy is continually evolving, raising the need to explore the current situation in order to understand the potential impact of any changes. Although community pharmacy has the potential to play a greater role in health care, it is currently not meeting this potential. To investigate the nature of the contemporary practice of community pharmacy in Australia and examine the potential missed opportunities for role expansion in health care. In-depth semi-structured interviews with a wide-range of key stakeholders within and beyond community pharmacy circles were conducted. Interviews were audio-recorded, transcribed verbatim and analyzed for emerging themes. Twenty-seven key informants across Eastern half of Australia were interviewed between December 2014 and August 2015. Several key elements of the current situation representing the social, economic and policy context of community pharmacy have been identified. These elements operate interdependently, influence micro, meso and macro levels of community pharmacy operation and are changing in the current climate. Community pharmacy has untapped potential in primary health care, but it has been slow to change to meet opportunities available in the current situation. As the current situation is complex, interrelated and dynamic with often unintended and unpredictable consequences, this paper suggests that policy makers to consider the micro, meso and macro levels of community pharmacy operation when making significant policy changes. The framework proposed in this study can be a helpful tool to analyze the processes operating at these three levels and their influences on practice. Copyright © 2016 Elsevier Inc.

  6. The current practice trends in pediatric bone-anchored hearing aids in Canada: a national clinical and surgical practice survey

    Science.gov (United States)

    2013-01-01

    Background Since the introduction of bone-anchored hearing aids (BAHAs) in the 1980s, the practices of surgeons who implant these hearing aids have become varied; different indications and surgical techniques are utilized depending on the surgeon and institution. The objective of the current study is to describe the clinical and surgical practices of otolaryngologists in Canada who perform pediatric BAHA operations. Methods A detailed practice questionnaire was devised and sent to all members of the Canadian Society of Otolaryngology-Head and Neck Surgery. Those who performed pediatric BAHA surgeries were asked to participate. Results Twelve responses were received (response rate of 80%). All of the respondents identified congenital aural atresia to be an indication for pediatric BAHAs. Other indications were chronic otitis externa or media with hearing loss (92%), allergic reactions to conventional hearing aids (75%), congenital fixation or anomaly of ossicular chain (67%), and unilateral deafness (25%). Minor complications, such as skin reactions, were reported in 25% of cases, while major complications were very rare. There was great variability with regards to surgical techinque and post-operative management. The extent of financial support for the BAHA hardware and device also varied between provinces, and even within the same province. Conclusion There is a lack of general consensus regarding pediatric BAHA surgeries in Canada. With such a small community of otolaryngologists performing this procedure, we are hopeful that this survey can serve as an impetus for a national collaboration to establish a set of general management principles and inspire multi-site research ventures.

    Full Text Available The current dispute resolution procedures available in the Malaysian construction industry are mainly litigation and arbitration. In addition, the alternative dispute resolutions (ADR, namely mediation and adjudication, have also been introduced as the other methods for resolving disputes. The objective of this study is to examine the current practice of dispute resolution and ADR available in the Malaysian construction industry. The aim of this paper is two-fold: to report the current practice of dispute resolution and ADR, and identify the attributes of successful implementation of both mechanisms based on the perceptions of the Malaysian construction industry players. From the jurisprudence point of view, this study looks into the law as it is, in relation to the current practice of dispute resolution and ADR, by showing how those findings can be used to explain why improvement is needed to promote a successful and well received dispute resolution and ADR, and what lessons can be learnt, towards the formulation of a more viable methods for the Malaysian construction industry. NVivo software has been used to manage and organise the complete interview transcripts and facilitate the data analysis process for this study. Literature review reveals a continuous development of dispute resolution and ADR in the Malaysian construction industry, while, globally the industry has not only embraced ADR but also spearheaded the development of innovative forms of dispute avoidance mechanism. The findings of interviews show that locally, apart from litigation, the common types of ADR are arbitration, mediation and ad hoc mechanism. The findings also lead to the discovery of the following attributes: faster, less procedural, cost effective and enforceable; regulation and government's support; professionalism and ethic; training; and facility, that may promote a successful implementation of dispute resolution and ADR in Malaysia.

Ophthalmologists who treat UM. (A) Medical records review of all Medicare beneficiaries tested by UM gene expression profile in 2012, conducted under an institutional review board-approved protocol. (B) 109 ophthalmologists specializing in the treatment of UM were invited to participate in 24-question survey in 2012; 72 were invited to participate in a 23-question survey in 2014. Responses analyzed by descriptive statistics, frequency analyses (percentages, Tukey, histograms), and Fisher's exact test. Descriptive presentation of essay answers. The review of Medicare medical records included 191 evaluable patients, 88 (46%) with documented medical treatment actions or institutional policies related to surveillance plans. Of these 88, all gene expression profiling (GEP) Class 1 UM patients were treated with low-intensity surveillance. All GEP Class 2 UM patients were treated with high-intensity surveillance (P<0.0001 versus Class 1). There were 36 (19%) with information concerning referrals after initial diagnosis. Of these 36, all 23 Class 2 patients were referred to medical oncology; however, none of the 13 Class 1 patients were referred (P<0.0001 versus Class 1). Only Class 2 patients were recommended for adjunctive treatment regimens. 2012 survey: 50 respondents with an annual median of 35 new UM patients. The majority of respondents (82%) performed molecular analysis of UM tumors after fine needle biopsy (FNAB); median: 15 FNAB per year; 2014 survey: 35 respondents with an annual median of 30 new UM patients. The majority offered molecular analyses of UM tumor samples to most patients. Patients with low metastatic risk (disomy 3 or GEP Class 1) were generally assigned to less frequent (every 6 or 12 months) and less intensive clinical visits. Patients with high metastatic

    Full Text Available Michael J Wolyniak,1 Lynne T Bemis,2 Amy J Prunuske2 1Department of Biology, Hampden-Sydney College, Hampden-Sydney, VA, 2Department of Biomedical Sciences, University of Minnesota Medical School, Duluth, MN, USA Abstract: Genetics is an essential subject to be mastered by health professional students of all types. However, technological advances in genomics and recent pedagogical research have changed the way in which many medical training programs teach genetics to their students. These advances favor a more experience-based education focused primarily on developing student's critical thinking skills. In this review, we examine the current state of genetics education at both the preclinical and clinical levels and the ways in which medical and pedagogical research have guided reforms to current and emerging teaching practices in genetics. We discover exciting trends taking place in which genetics is integrated with other scientific disciplines both horizontally and vertically across medical curricula to emphasize training in scientific critical thinking skills among students via the evaluation of clinical evidence and consultation of online databases. These trends will produce future health professionals with the skills and confidence necessary to embrace the new tools of medical practice that have emerged from scientific advances in genetics, genomics, and bioinformatics.

    Mass casualty decontamination is a public health intervention that would be employed by emergency responders following a chemical, biological, or radiological incident. The decontamination of large numbers of casualties is currently most often performed with water to remove contaminants from the skin surface. An online survey was conducted to explore US fire departments' decontamination practices and their preparedness for responding to incidents involving mass casualty decontamination. Survey respondents were asked to provide details of various aspects of their decontamination procedures, including expected response times to reach casualties, disrobing procedures, approaches to decontamination, characteristics of the decontamination showering process, provision for special populations, and any actions taken following decontamination. The aim of the survey was to identify any differences in the way in which decontamination guidance is implemented across US states. Results revealed that, in line with current guidance, many US fire departments routinely use the "ladder-pipe system" for conducting rapid, gross decontamination of casualties. The survey revealed significant variability in ladder-pipe construction, such as the position and number of fire hoses used. There was also variability in decontamination characteristics, such as water temperature and water pressure, detergent use, and shower duration. The results presented here provide important insights into the ways in which implementation of decontamination guidance can vary between US states. These inconsistencies are thought to reflect established perceived best practices and local adaptation of response plans to address practical and logistical constraints. These outcomes highlight the need for evidence-based national guidelines for conducting mass casualty decontamination.

  12. Current pharmacotherapy for obesity: extrapolation of clinical trials data to practice.

    2014-04-01

    When used prudently and in combination with lifestyle modification, pharmacotherapy has an important role in the management of obesity. This review covers targets for antiobesity drugs, challenges and limitations, failed translation of basic science to clinical practice, methodological and regulatory issues in clinical trials of pharmacotherapy, efficacy and risks of drugs currently approved for obesity, and clinical practice issues when using antiobesity drugs with emphasis on recently approved drugs. Drugs currently approved for long-term therapy of obesity offer modest benefits for most patients, substantial benefits for some and no benefits for others. Numerous methodological problems including exclusion of the type of patients who are most often seen in clinical practices, inadequate enrollment of men and minorities, exclusion of patients taking antidepressants, high dropout rates, lack of follow-up after treatment discontinuation, and less than ideal imputation methods in data analysis limit the interpretation of clinical trials data and generalizability. Single-drug therapies offer small to moderate weight-loss benefits, but are generally better tolerated. Efficacy is enhanced with combination drug therapies, but so are the hazards. Clinicians should base their decisions on the expected and observed benefit-to-risk balance.

    In the development of new generation EIT systems, the design of a steady current generator with broad bandwidth is an important consideration. In this paper, the current generator is constructed by enhanced Howland circuit with high-speed operational amplifier. The electronic models of current generator built on Orcad PSpice 9.2 software are simulated to observe the output current stability at multi-frequencies. As results, the THS4021 model provides stable output current at the frequency ranging from 10 k to 1 MHz with the load for 200-2 kOmega. Furthermore, it also offers higher output impedance that equal to 2.1 MOmega at 1 MHz. The results of simulations provide useful approaches of current generator design for EIT system.

    Full Text Available The purpose of this paper is to generally present possibilities of the current conveyor use in the well-known active electronic circuits. Current conveyors are able to substitute all known active elements. This claim is supported by the fact, that four basic functional block structures can be realized by use of current conveyors - voltage-controlled voltage source, voltage-controlled current source, current-controlled current source and current-controlled voltage source. The paper presents particular example of use of functional block structure with current conveyors in Wien bridge oscillator, where it successfully substitutes operational amplifier on the place of active element. Both theoretical formulae and design description are given. Finally, OrCAD PSpice simulation results are presented.

    Full Text Available In this paper we demonstrate the design of a low-cost optical current sensor. The sensor principle is the Faraday rotation of a light beam through a magneto-optical material, SF2, when a magnetic field is present. The prototype has a high sensitivity and a high linearity for currents ranging from 0 up to 800 A. The error of the optical fibre sensor is smaller than 1% for electric currents over 175 A.

    Full Text Available Magnetic resonance imaging (MRI, frequently with contrast enhancement, is the preferred imaging modality for many indications in children. Practice varies widely between centers, reflecting the rapid pace of change and the need for further research. Guideline changes, for example on contrast-medium choice, require continued practice reappraisal. This article reviews recent developments in pediatric contrast-enhanced MRI and offers recommendations on current best practice. Nine leading pediatric radiologists from internationally recognized radiology centers convened at a consensus meeting in Bordeaux, France, to discuss applications of contrast-enhanced MRI across a range of indications in children. Review of the literature indicated that few published data provide guidance on best practice in pediatric MRI. Discussion among the experts concluded that MRI is preferred over ionizing-radiation modalities for many indications, with advantages in safety and efficacy. Awareness of age-specific adaptations in MRI technique can optimize image quality. Gadolinium-based contrast media are recommended for enhancing imaging quality. The choice of most appropriate contrast medium should be based on criteria of safety, tolerability, and efficacy, characterized in age-specific clinical trials and personal experience.

    This paper reviews three recent reports of national gender trends in dental practice patterns. Although the three independent cross-sectional studies were conducted at different points in time, used different sampling strategies, and used similar but independent survey instruments, findings were consistent across studies. In summary: Women dentists are less likely to be married and have fewer children. Women are more likely to assume child rearing and household responsibilities. Women are less likely to be practice owners. Women worked slightly fewer hours per week and weeks per year, and were more likely to take a leave of absence for illness or child rearing. However, women dentists demonstrate a far greater professional work commitment than was previously reported in the literature. Women earn significantly less income from the practice of dentistry, even after controlling for age, practice ownership, hours worked per week, and other personal characteristics. The most current "Gender Wage Gap" estimates range from 57.7% for specialists to 75.4% for general practitioners (8). delta.

    We are fortunate to live in a time when real advances in medicine are happening at an increasingly rapid pace. This is especially true in the field of radiology, and keeping abreast of these advances is one of the main challenges of clinical practice. Traditionally, cutting edge techniques in our field have been researched and validated at major academic medical centers before slowly making their way into the armamentarium of routine clinical practice. However, the improved ability to communicate and disseminate information in our modern age has facilitated more rapid implementation of new techniques to allow us to better serve our patients. As such, this article aims to review the current standards for MRI of the shoulder used in routine practice. Furthermore, we will discuss some of the most recent advances in shoulder MRI, with particular emphasis on the applicability of an additional axial 3D T1-weighted FLASH sequence with Dixon-based water-fat separation in routine clinical practice that can be useful in characterizing several commonly encountered pathologic processes of the shoulder joint.

    Full Text Available OBJECTIVE: The aim of this study was to analyze qualitatively how women, who have recovered from anorexia nervosa, perceive and describe their current eating practices, as well as the ones developed during the eating disorder period. METHODS: Seven women were interviewed individually with the objective of investigating their eating practices, transition phases and all relevant aspects that somewhat contributed to the habit-forming; experiences, feelings and perceptions related to mealtime and the influence that food has had over the present subjects' life. The interviews were analyzed by the discourse of the collective subject method. RESULTS: The results brought up the following topics: a control; b concerns and feelings; c deprivation d beauty dictatorship; e eating competence; f importance of food; g food cacophony. CONCLUSIONS: What stands out is a multiplicity of eating practices, which during the eating disorder were similar to and characterized by restriction; however, after recovery, part of the subjects seem to have developed a higher eating competence, whereas others show a practice similar to the one acquired during the anorexia nervosa, such as the difficulty in realizing when they are satisfied and a feeling of discomfort when facing social interactions.
