    This paper reports on the outcomes of a small well designed pilot study. Pilot studies often disseminate limited or statistically meaningless results without adding to the body knowledge on the comparative research benefits. The design a pre-test post-test group parallel randomised control trial and inductive content analysis of focus group transcripts was tested specifically to increase outcomes in a proposed larger study. Strategies are now in place to overcome operational barriers and recruitment difficulties. Links between the qualitative and quantitative arms of the proposed larger study have been made; it is anticipated that this will add depth to the final report. More extensive reporting on the outcomes of pilot studies would assist researchers and increase the body of knowledge in this area.

    Undertaking a research project is mandatory for MD Psychiatry trainees. The present study was undertaken to assess the type of research activity being undertaken as part of MD Psychiatry dissertation, and its contribution to national and international literature. Three medical colleges supplied the data about the topic, names of the supervisor and the candidate, collaboration, funding accrued, and publication details of MD-based research carried out between years 2000 and 2010 inclusive; 95 records were collected for the final analysis. The details of the publications provided were cross-checked on the internet, which would have taken care of missed publications as well. Most studies were single-point assessment clinical studies. Only 2 studies had been funded, 11 had collaboration with other departments within the same institute, and 5 had inter-institute collaborations. Majority of the studies were not published. Only 30 were published as full paper and 9 as abstracts. Of these 30 full publications, only 3 were published in journals having JCI impact factor values (1.4, 1.3, and 1.4, respectively). The main finding of this pilot study was that MD-based research has low contribution to the national and international literature, and those articles which are published are in low impact journals. Suggestions for modifying this state of affairs are discussed.

    Full Text Available Conducting research in the area of sexual violence has complex ethical and practical challenges for the researcher. Managing ethical issues in sexual violence is important and can be achieved through the use of pilot studies. The primary purpose of the pilot study was to identify and manage potential ethical and practical problems that could jeopardise the main study or violate the ethical and human rights of participants in the main study on women’s journey of recovery from sexual assault. The secondary purpose was to collect preliminary data in order to determine the human, financial and time resources needed for a planned study. The methods and processes used in conducting the pilot study in the study on women’s journey of recovery are discussed according to each of the objectives of the pilot study, methods used to achieve the objective, observations or findings made during the pilot study, and implications for the main study. This article aims to demonstrate how a pilot study was used to manage identified potential ethical and practical research issues during the recruitment of participants and data collection for the research that was conducted by the first author to investigate women’s journey of recovery from sexual assault trauma within the first week following sexual assault.

    2017-07-01

    Feasibility and pilot study designs are common in palliative care research. Finding standard guidelines on the structure and reporting of these study types is difficult. In feasibility and pilot studies in palliative care research, to determine 1) how commonly a priori feasibility are criteria reported and whether results are subsequently reported against these criteria? and 2) how commonly are participants' views on acceptability of burden of the study protocol assessed? Four databases (OVID Medline, EMBASE, CINAHL, and PubMed via caresearch.com.au.) were searched. Search terms included palliative care, terminal care, advance care planning, hospice, pilot, feasibility, with a publication date between January 1, 2012 and December 31, 2013. Articles were selected and appraised by two independent reviewers. Fifty-six feasibility and/or pilot studies were included in this review. Only three studies had clear a priori criteria to measure success. Sixteen studies reported participant acceptability or burden with measures. Forty-eight studies concluded feasibility. The terms "feasibility" and "pilot" are used synonymously in palliative care research when describing studies that test for feasibility. Few studies in palliative care research outline clear criteria for success. The assessment of participant acceptability and burden is uncommon. A gold standard for feasibility study design in palliative care research that includes both clear criteria for success and testing of the study protocol for participant acceptability and burden is needed. Such a standard would assist with consistency in the design, conduct and reporting of feasibility and pilot studies. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    1984-01-01

    In May 1980 it was decided to organize an intercomparison of personal dosimeters for photon radiations. The Commission of the European Communities initiated the intercomparison by starting a pilot study in which three laboratories NPL (United Kingdom), PTB (Germany) and RIV (The Netherlands) were asked to irradiate a series of personal dosemeters from institutes, GSF (Muenchen), CEA (Fontenay-aux-Roses), CNEN (Bologna) and CEGB (Berkeley). The latter institutes are secondary standard laboratories and have a radiation protection service as well. A new aspect of this pilot study is the fact that the irradiations also take place in front of a phantom. Irradiations took place in July and August 1980. The results of 4 institutes show that the personal dosemeters are quite capable of measuring the backscattered photon components

    2017-09-01

    Obtaining voluntary informed consent for research participation is an ethical imperative, yet there appears to be little consensus regarding what constitutes a voluntary consent decision. An instrument to assess influences on participants' consent decision and perceived voluntariness was developed and piloted in two South African HIV clinical trials. The pilot study found high levels of perceived voluntariness. The feeling of having no choice but to participate was significantly associated with lower perceived voluntariness. Overall the data suggest that it is possible to obtain voluntary and valid consent for research participants in ethically complex HIV clinical trials in a developing country context.

    Directory of Open Access Journals (Sweden)

    Evalina van Wijk RN, PhD

    2013-02-01

    Full Text Available The purpose of the researcher's study was to examine the meaning that intimate partners of female rape victims attached to their lived experiences after the rape. The conduct of qualitative research concerning non-offending partners of female rape victims, however, often involves multifaceted ethical and practical challenges, which can be managed through the use of pilot studies. The pilot study described in this report had three objectives. The first was to pretest and refine the proposed method for locating, accessing, and recruiting intimate partners of female rape victims, within the first two weeks after the rape, for participation in a six-month longitudinal study. The second objective was to identify and prevent all possible risk factors in the proposed recruitment and data collection methods that could harm the participants' safety during the main study. The third objective was to determine the feasibility of the main study, in terms of the limited financial and human resources available. The pilot phase was valuable in identifying ethical and methodological problems during the recruitment of participants and collection of data. It allowed for methodological adjustments prior to the main study and confirmed the feasibility of the overall research design. A pilot, pretesting phase is therefore seen as an essential component of a qualitative study involving a vulnerable population.

    2018-01-01

    To describe whether an action learning-inspired journal club for nurse leaders can develop the leaders' self-perceived competences to support a research culture in clinical nursing practice. Development of clinical research capacity and nurse leaders with the requisite competences are key factors in evidence-based health care practice. This study describes how nurse leaders at a large regional hospital took part in a journal club for nurse leaders, with a view to developing their competences to support a nursing research culture in their departments. A pilot study using a multimethod approach to evaluate the journal club for nurse leaders. Four nurse leaders participated in the journal club for nurse leaders. Content analysis on the data was performed. Data revealed that participation in journal club for nurse leaders gave the leaders a feeling of increased competences to support nursing research culture in their departments. They stated that the action learning approach and the competences of the facilitator were key factors in this outcome. An action learning-inspired journal club for nurse leaders can be useful and meaningful to nurse leaders in developing leadership competences. As an approach in journal club for nurse leaders, action learning can develop nurse leaders' competence to support a research culture, and thus ensure evidence-based nursing is practised. © 2017 John Wiley & Sons Ltd.

    2009-07-01

    Full Text Available Abstract Background There is some evidence that medical students consider population health issues less important than other domains in the health sciences and attitudes to this field may become more negative as training progresses. A need to improve research skills among medical students has also been suggested. Therefore we piloted an integrative teaching exercise that combined teaching of research skills and public health, with real-world research. Methods Third year medical students at the University of Otago (Dunedin, New Zealand filled in a questionnaire on their housing conditions and health. The students were given the results of the survey to discuss in a subsequent class. Student response to this teaching exercise was assessed using a Course Evaluation Questionnaire. Results Of the 210 students in the class, 136 completed the Course Evaluation Questionnaire (65%. A majority of those who responded (77% greatly supported or supported the use of the survey and seminar discussion for future third year classes. Most (70% thought that the session had made them more aware and concerned about societal problems, and 72% felt that they now had an improved understanding of the environmental determinants of health. Students liked the relevance and interaction of the session, but thought it could be improved by the inclusion of small group discussion. The findings of the students' housing and health were considered by the tutors to be of sufficient value to submit to a scientific journal and are now contributing to community action to improve student housing in the city. Conclusion In this pilot study it was feasible to integrate medical student teaching with real-world research. A large majority of the students responded favourably to the teaching exercise and this was generally successful in raising the profile of public health and research. This approach to integrated teaching/research should be considered further in health sciences training and

    Many hospital information systems have been developed and implemented to collect clinical data from the bedside and have used the information to improve patient care. Because of a growing awareness that the use of clinical information improves quality of care and patient outcomes, measuring tools (electronic and paper based) have been developed, but most of them require multiple steps of data collection and analysis. This necessitated the development of a Web-based Nursing Practice and Research Information Management System that processes clinical nursing data to measure nurses' delivery of care and its impact on patient outcomes and provides useful information to clinicians, administrators, researchers, and policy makers at the point of care. This pilot study developed a computer algorithm based on a falls prevention protocol and programmed the prototype Web-based Nursing Practice and Research Information Management System. It successfully measured performance of nursing care delivered and its impact on patient outcomes successfully using clinical nursing data from the study site. Although Nursing Practice and Research Information Management System was tested with small data sets, results of study revealed that it has the potential to measure nurses' delivery of care and its impact on patient outcomes, while pinpointing components of nursing process in need of improvement.

    No studies have sought to provide a quantitative or qualitative critique of research in the field of neurointerventional surgery. To analyze recent publications from the Journal of Neurointerventional Surgery ( JNIS ) to test a new method for assessing research and collaboration. We reviewed all JNIS Online First publications from 25 February 2015 to 24 February 2016. All publications-human or non-human research, systematic reviews, meta-analyses, or literature reviews-were included; editorials and commentaries were excluded. For each publication, study design, number of patients, authors, contributing centers, and study subject were recorded. Level of evidence was defined using a new scale. A total of 206 articles met inclusion criteria. Only 4% were prospective studies. Twenty-eight per cent of scientific research featured patient series of nine or less. The majority of publications were categorized as low-level evidence (91%). Forty-seven per cent involved individuals from a single center, with 87% having collaboration from three or fewer centers. International collaboration was present in 19%. While 256 institutions from 31 countries were represented, 66% were represented in only one publication. We queried JNIS Online First articles from a 1-year period in a pilot study to test a new method of analyzing research quality and collaboration. The methodology appears to adequately quantify the studies into evidence tiers that emulate previously published, widely accepted scales. This may be useful for future comparison of peer-reviewed journals or for studying the quality of research being performed in different disease processes or medical specialties.

    Few Asian-American women participate in cancer treatment trials. In a pilot study to assess barriers to participation, we mailed surveys to 132 oncologists and interviewed 19 Asian-American women with cancer from Northern California. Forty-four oncologists responded. They reported as barriers language problems, lack of culturally relevant cancer information, and complex protocols. Most stated that they informed Asian-American women about treatment trials. Only four women interviewed knew about trials. Other patient-identified barriers were fear of side effects, language problems, competing needs, and fear of experimentation. Family decision making was a barrier for both oncologists and patients. Compared to non-Asian oncologists, more Asian oncologists have referred Asian-American women to industry trials and identified barriers similar to patients' reports. Our findings indicate that Asian-American women need to be informed about cancer treatment trials, linguistic barriers should be addressed, and future research should evaluate cultural barriers such as family decision making.

    Insights from genetic research may greatly improve our understanding of physical and mental illnesses and assist in the prevention of disease. Early experience with genetic information suggests that it may lead to stigma, discrimination, and other psychosocial harms, however, and this may be particularly salient in some settings, such as the workplace. Despite the importance of these issues, little is known about how healthy adults, including workers, perceive and understand ethically important issues in genetic research pertaining to physical and mental illness. We developed, pilot tested, and administered a written survey and structured interview to 63 healthy working adults in 2 settings. For this paper, we analyzed a subset of items that assessed attitudes toward ethically relevant issues related to participation in genetic research on physical and mental illness, such as its perceived importance, its acceptability for various populations, and appropriate motivations for participation. Our respondents strongly endorsed the importance of physical and mental illness genetic research. They viewed participation as somewhat to very acceptable for all 12 special population groups we asked about, including persons with mental illness. They perceived more positives than negatives in genetic research participation, giving neutral responses regarding potential risks. They affirmed many motivations for participation to varying degrees. Men tended to affirm genetic research participation importance, acceptability, and motivations more strongly than women. Healthy working persons may be willing partners in genetic research related to physical and mental illnesses in coming years. This project suggests the feasibility and value of evidence-based ethics inquiry, although further study is necessary. Evidence regarding stakeholders' perspectives on ethically important issues in science may help in the development of research practices and policy.

    Loneliness in older people is associated with poor health-related quality of life (HRQoL). We undertook a parallel-group randomised controlled trial to evaluate the effectiveness and cost-effectiveness of telephone befriending for the maintenance of HRQoL in older people. An internal pilot tested the feasibility of the trial and intervention. Participants aged >74 years, with good cognitive function, living independently in one UK city were recruited through general practices and other sources, then randomised to: (1) 6 weeks of short one-to-one telephone calls, followed by 12 weeks of group telephone calls with up to six participants, led by a trained volunteer facilitator; or (2) a control group. The main trial required the recruitment of 248 participants in a 1-year accrual window, of whom 124 were to receive telephone befriending. The pilot specified three success criteria which had to be met in order to progress the main trial to completion: recruitment of 68 participants in 95 days; retention of 80% participants at 6 months; successful delivery of telephone befriending by local franchise of national charity. The primary clinical outcome was the Short Form (36) Health Instrument (SF-36) Mental Health (MH) dimension score collected by telephone 6 months following randomisation. We informed 9,579 older people about the study. Seventy consenting participants were randomised to the pilot in 95 days, with 56 (80%) providing valid primary outcome data (26 intervention, 30 control). Twenty-four participants randomly allocated to the research arm actually received telephone befriending due to poor recruitment and retention of volunteer facilitators. The trial was closed early as a result. The mean 6-month SF-36 MH scores were 78 (SD 18) and 71 (SD 21) for the intervention and control groups, respectively (mean difference, 7; 95% CI, -3 to 16). Recruitment and retention of participants to a definitive trial with a recruitment window of 1 year is feasible. For

    Full Text Available Background: Higher Education Institutions (HEIs need to ensure that the education provided meets the student’s and employer’s requirements, for today and the future. However, in addition to the challenges of teaching and learning, internationalisation, globalisation and world university rankings are rearing their heads thus increasing the demands made on many HEIs. Objective: One of the ways in which HEIs can make their mark is through world university rankings. This may be achieved by exposing more information on new and innovative research knowledge to the broader community in the global market via research publications that attract citations on open access platforms, hence influencing the university’s ranking. For this purpose and intent, a ‘simple’ and ‘easy-to-use’ online web tool was developed at a HEI. The aim was to have research publications submitted via the Online Research Output Submission System (OROSS tool, screened and deposited in the institution’s open access database. Method: Training was provided to the relevant participants and a survey was conducted to ascertain the participants’ perceptions about the utilisation of the OROSS tool and the training provided. Conclusion: This article reflects on the pilot phase of a longitudinal study. Results of an evaluation conducted by the researcher of the OROSS application from a user perspective (process are highlighted. In general, users rated OROSS favourably in terms of it being a useful, simple and easy-to-use web-based tool. The findings of this study may assist University of Johannesburg’s executive management in deciding the fate of the OROSS tool for future use.

    Research participants often fail to recall substantial amounts of informed consent information after delays of only a few days. Numerous interventions have proven effective at improving consent recall; however, virtually all have focused on compensating for potential cognitive deficits and have ignored motivational factors. In this pilot study, we randomly assigned 31 drug court clients participating in a clinical research trial to a standard consent procedure or to the same procedure plus incentives for correctly recalling consent information. The incentive group was told they would receive $5 for each of the 15 consent items they could answer correctly 1-week later. At the follow-up, the incentive group recalled a significantly greater percentage of consent information overall than the standard group (65% vs. 42%; p < .01). Similar findings were observed for specific categories of consent information, including study purpose and design, risks and benefits, and human subject protections. Effect sizes were all large (d = 0.89 to 1.25). Findings suggest that motivation plays a key role in recall of consent information and should be considered in the development of future interventions.

    Co-creation (or co-design) represents the highest form of stakeholder engagement, but it can be infeasible to co-create with all stakeholders through all stages of a research project. The choice of stakeholders for co-design will depend on the study purpose and context of change. For this deprescribing pilot study, general practitioners were recognised as a critical gateway for co-creation, with patients' perspectives of the deprescribing process to be assessed in the evaluation of the pilot.

    Educational methods for residents are shifting toward greater learner independence aided by technological advances. A Web-based program using a podcast was created for resident EEG instruction, replacing conventional didactics. The EEG curriculum also consisted of EEG interpretations under the tutelage of a neurophysiologist. This pilot study aimed to objectively evaluate the effectiveness of the podcast as a new teaching tool. A podcast for resident EEG instruction was implemented on the Web, replacing the traditional lecture. After Institutional Review Board approval, consent was obtained from the participating residents. Using 25-question evaluation tools, participants were assessed at baseline before any EEG instruction, and reassessed after podcasting and after 10 clinical EEG exposures. Each 25-item evaluation tool contained tracings used for clinical EEG interpretations. Scores after podcast training were also compared to scores after traditional didactic training from a previous study among anesthesiology trainees. Ten anesthesiology residents completed the study. The mean scores with standard deviations are 9.50 ± 2.92 at baseline, 13.40 ± 3.31 (p = 0.034) after the podcast, and 16.20 ± 1.87 (p = 0.019) after interpreting 10 EEGs. No differences were noted between the mean educational tool scores for those who underwent podcasting training compared to those who had undergone traditional didactic training. In this pilot study, podcast training was as effective as the prior conventional lecture in meeting the curricular goals of increasing EEG knowledge after 10 EEG interpretations as measured by assessment tools.

    Full Text Available Abstract Background Medical research must involve the participation of human subjects. Knowledge of patients' perspectives and concerns with their involvement in research would enhance recruitment efforts, improve the informed consent process, and enhance the overall trust between patients and investigators. Several studies have examined the views of patients from Western countries. There is limited empirical research involving the perspectives of individuals from developing countries. The purpose of this study is to examine the attitudes of Egyptian individuals toward medical research. Such information would help clarify the type and extent of concerns regarding research participation of individuals from cultural, economic, and political backgrounds that differ from those in developed countries. Methods We conducted semi-structured interviews with 15 Egyptian individuals recruited from the outpatient settings (public and private at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. Thematic analysis followed. Results All individuals valued the importance of medical research; however most would not participate in research that involved more than minimal risk. Individuals were comfortable with studies involving surveys and blood sampling, but many viewed drug trials as being too risky. All participants valued the concept of informed consent, as they thought that their permission to be in a research study was paramount. Many participants had discomfort with or difficulty in the understanding several research concepts: randomization, double-blind, and clinical equipoise. Trust in the physicians performing research was important in deciding to participate in clinical research. The small sample size and the selection bias associated with obtaining information from only those who agreed to participate in a research study represent limitations in this study. Conclusion Overall, individuals in our sample recognize

    To assess parental permission for a neonate's research participation using the MacArthur competence assessment tool for clinical research (MacCAT-CR), specifically testing the components of understanding, appreciation, reasoning and choice. Quantitative interviews using study-specific MacCAT-CR tools. Parents of critically ill newborns would produce comparable MacCAT-CR scores to healthy adult controls despite the emotional stress of an infant with critical heart disease or the urgency of surgery. Parents of infants diagnosed prenatally would have higher MacCAT-CR scores than parents of infants diagnosed postnatally. There would be no difference in MacCAT-CR scores between parents with respect to gender or whether they did or did not permit research participation. Parents of neonates undergoing cardiac surgery who had made decisions about research participation before their neonate's surgery. The MacCAT-CR. 35 parents (18 mothers; 17 fathers) of 24 neonates completed 55 interviews for one or more of three studies. Total scores: magnetic resonance imaging (mean 36.6, SD 7.71), genetics (mean 38.8, SD 3.44), heart rate variability (mean 37.7, SD 3.30). Parents generally scored higher than published subject populations and were comparable to published control populations with some exceptions. The MacCAT-CR can be used to assess parental permission for neonatal research participation. Despite the stress of a critically ill neonate requiring surgery, parents were able to understand study-specific information and make informed decisions to permit their neonate's participation.

    Evidence Based Medicine (EBM) is increasingly being applied to inform clinical decision-making in orthopaedic surgery. Despite the promotion of EBM in Orthopaedic Surgery, the adoption of results from high quality clinical research seems highly unpredictable and does not appear to be driven strictly by randomized trial data. The objective of this study was to pilot a survey to determine if we could identify surgeon opinions on the characteristics of research studies that are perceived as being most likely to influence clinical decision-making among orthopaedic surgeons in Canada. A 28-question electronic survey was distributed to active members of the Canadian Orthopaedic Association (COA) over a period of 11 weeks. The questionnaire sought to analyze the influence of both extrinsic and intrinsic characteristics of research studies and their potential to influence practice patterns. Extrinsic factors included the perceived journal quality and investigator profiles, economic impact, peer/patient/industry influence and individual surgeon residency/fellowship training experiences. Intrinsic factors included study design, sample size, and outcomes reported. Descriptive statistics are provided. Of the 109 members of the COA who opened the survey, 95 (87%) completed the survey in its entirety. The overall response rate was 11% (95/841). Surgeons achieved consensus on the influence of three key designs on their practices: 1) randomized controlled trials 94 (99%), 2) meta-analysis 83 (87%), and 3) systematic reviews 81 (85%). Sixty-seven percent of surgeons agreed that studies with sample sizes of 101-500 or more were more likely to influence clinical practice than smaller studies (n = design influencing adoption included 1) reputation of the investigators (99%) and 2) perceived quality of the journal (75%). Although study design and sample size (i.e. minimum of 100 patients) have some influence on clinical decision making, surgeon respondents are equally influenced

Of 276 participating students, 80 (29% responded to the study survey. As a result, 19% of respondents were more likely to pursue a career in science, and 27.5% were more likely to pursue a career in epidemiology. Only one respondent reported being less likely to pursue a science career, while seven were less likely to pursue epidemiology. A majority of respondents felt that the poster experience was on par with, or superior to, a comparable research paper, in terms of both educational appeal and enjoyment. Mandatory, formal poster presentations are an innovative format for teaching advanced health sciences, and may more accurately reflect the realities of a science career than do more traditional educational formats.

    The purpose of the current study was to evaluate efficacy of techniques adapted from situation awareness research for describing how older adults perceive and understand fall risk factors in the context of daily routine. Eleven older adults watched a video of an older woman performing daily activities. Thirteen intrinsic, extrinsic, and behavioral fall risks were embedded throughout the scenario. The video was periodically frozen/blanked from view while participants answered questions about their understanding of the situation and associated story elements. Participants perceived a variety of fall risk factors but did not necessarily interpret them as indicating fall risk. Many fall risks held non-fall meaning for participants (e.g., newspapers on the floor meant the woman liked to read). Although four participants readily identified a fall risk situation, seven did not until they were explicitly asked to consider safety. Study techniques were effective for describing situation awareness of fall risk and several suggestions for improvement are described. [Res Gerontol Nurs. 2016; 9(4):161-166.].

    A repeated-measures pilot study was used to investigate acoustic changes in the voices of participants in a Fitzmaurice Voicework (FV) teacher certification program. Maximum phonation time (MPT) was also measured. Eleven participants with no reported voice problems were studied. Pretraining and posttraining recordings were made of each participant. Measures of MPT were made, and the recordings were analyzed for jitter, shimmer, and noise-to-harmonics ratio (NHR). The measure of effect size for MPT was moderate, and there was an overall increase in MPT from pretraining to posttraining, with 70% of participants showing an increase in MPT. The measure of effect sizes for jitter, shimmer, and NHR were small, with measurements showing no significant changes from pretraining to posttraining. There were indications that FV training may have positive outcomes for actors and professional voice users, particularly in increasing MPT. Further studies with larger subject groups are needed to investigate the significance of the increase in MPT noted in this study and to test whether FV training can help to lower rates of shimmer and jitter.

    Full Text Available Perfluoroalkylated substances (PFASs are a class of synthetic chemicals used in a wide range of processes and products due to their unique physicalchemical properties. Through intake of PFASs via food or several consumer products, humans can be exposed. Long-chain PFASs have been associated with adverse effects in laboratory animals, and there is also evidence for adverse health effects in humans. Although investigations of human exposure are mainly conducted in blood samples, some studies have shown that especially short-chain PFASs can be detected in human urine. In the present study, a sensitive analytical method was adapted for the measurement of 12 PFASs in human urine samples by HPLC-MS/MS. For verifying this method, concentrations in 11 male and female participants aged 25-46 years were analysed. In the study population, ranges of urinary PFASs concentrations were n.d.- 8.5 ng/l for perfluoropentanoic acid, study shows that several shortchain PFASs are detectable in human urine.

    This article is a report of the process and results of a feasibility pilot study to improve the quality of maternity care in a sample of 31 women and their newborns delivering in a public, tertiary hospital in the Dominican Republic. The pilot study was the first "action step" taken as a result of a formative, community-based participatory research (CBPR) study conducted between 2008 and 2010 by an interdisciplinary, international partnership of U.S. academic researchers, Dominican medical/nursing personnel, and Dominican community health workers. Health personnel and community health workers separately identified indicators most important to measure quality of antepartum maternity care: laboratory and diagnostic studies and respectful, interpersonal communication. At the midpoint and the completion of data collection, the CBPR team evaluated the change in quality indicators to assess improvement in care. The pilot study supports the idea that joint engagement of community health workers, health personnel, and academic researchers with data creation and patient monitoring is motivating for all to continue to improve services in the cultural context of the Dominican Republic. © The Author(s) 2014.

    Full Text Available In the spring of 2011, the UC San Diego Research Cyberinfrastructure (RCI Implementation Team invited researchers and research teams to participate in a research curation and data management pilot program. This invitation took the form of a campus-wide solicitation. More than two dozen applications were received and, after due deliberation, the RCI Oversight Committee selected five curation-intensive projects. These projects were chosen based on a number of criteria, including how they represented campus research, varieties of topics, researcher engagement, and the various services required. The pilot process began in September 2011, and will be completed in early 2014. Extensive lessons learned from the pilots are being compiled and are being used in the on-going design and implementation of the permanent Research Data Curation Program in the UC San Diego Library. In this paper, we present specific implementation details of these various services, as well as lessons learned. The program focused on many aspects of contemporary scholarship, including data creation and storage, description and metadata creation, citation and publication, and long term preservation and access. Based on the lessons learned in our processes, the Research Data Curation Program will provide a suite of services from which campus users can pick and choose, as necessary. The program will provide support for the data management requirements from national funding agencies.

    Chemical treatment process for the low level liquid radioactive waste generated at PINSTECH was previously optimized on lab-scale making use of coprecipitation of hydrous oxides of iron in basic medium. Ferrous sulfate was used as coagulant. Batch wise application of this procedure on pilot scale has been tested on a 1200 L batch volume of typical PINSTECH liquid waste. Different parameters and unit operations have been evaluated. The required data for the construction of a small size treatment plant envisioned can be used for demonstration/teaching purpose as well as for the decontamination of the waste effluents of the Institute. The lab-scale process parameters were verified valid on pilot scale. It was observed that reagent doses can further be economized with out any deterioration of the Decontamination Factors (DF) achieved or of any other aspect of the process. This simple, cost- effective, DF-efficient and time-smart batch wise process could be coupled with an assortment of other treatment operations thus affording universal application. Observations recorded during this study are presented. (author)

    Currently on the International Space Station (ISS) and other space vehicles Caution & Warning (C&W) alerts are represented with various auditory tones that correspond to the type of event. This system relies on the crew's ability to remember what each tone represents in a high stress, high workload environment when responding to the alert. Furthermore, crew receive a year or more in advance of the mission that makes remembering the semantic meaning of the alerts more difficult. The current system works for missions conducted close to Earth where ground operators can assist as needed. On long duration missions, however, they will need to work off-nominal events autonomously. There is evidence that speech alarms may be easier and faster to recognize, especially during an off-nominal event. The Information Presentation Directed Research Project (FY07-FY09) funded by the Human Research Program included several studies investigating C&W alerts. The studies evaluated tone alerts currently in use with NASA flight deck displays along with candidate speech alerts. A follow-on study used four types of speech alerts to investigate how quickly various types of auditory alerts with and without a speech component - either at the beginning or at the end of the tone - can be identified. Even though crew were familiar with the tone alert from training or direct mission experience, alerts starting with a speech component were identified faster than alerts starting with a tone. The current study replicated the results from the previous study in a more rigorous experimental design to determine if the candidate speech alarms are ready for transition to operations or if more research is needed. Four types of alarms (caution, warning, fire, and depressurization) were presented to participants in both tone and speech formats in laboratory settings and later in the Human Exploration Research Analog (HERA). In the laboratory study, the alerts were presented by software and participants were

    In 2014, a qualitative multi-country research project was launched to study the reasons behind the high use of antibiotics in regions of Southeast Europe by using previously untrained national interviewers (who were engaged in other antibiotic microbial resistance-related investigations) to conduct qualitative interviews with local patients, physicians and pharmacists. Little knowledge exists about how to implement qualitative multi-country research collaborations involving previously untrained local data collectors. The aim of this paper was therefore to contribute to the knowledge regarding how to conduct these types of research projects by evaluating a pilot study of the project. Local data collectors conducted the study according to a developed protocol and evaluated the study with the responsible researcher-team from University of Copenhagen. The pilot study focused on 'local ownership', 'research quality' and 'feasibility' with regard to successful implementation and evaluation. The evaluation was achieved by interpreting 'Skype' and 'face to face' meetings and email correspondence by applying 'critical common sense'. Local data collectors achieved a sense of joint ownership. Overall, the protocol worked well. Several minor challenges pertaining to research quality and feasibility were identified, in particular obtaining narratives when conducting interviews and recruiting patients for the study. Furthermore, local data collectors found it difficult to allocate sufficient time to the project. Solutions were discussed and added to the protocol. Despite the challenges, it was possible to achieve an acceptable scientific level of research when conducting qualitative multi-country research collaboration under the given circumstances. Specific recommendations to achieve this are provided by the authors.

    Opioid misuse imposes a disproportionately heavy burden on individuals living in rural areas. Community pharmacy has the potential to expand and coordinate with health professionals to identify and intervene with those who misuse opioids. Rural and urban community pharmacy patients were recruited in this pilot project to describe and compare patterns of opioid misuse. We administered a health screening survey in 4 community pharmacies among patients filling opioid medications. Univariate statistics were used to assess differences in health characteristics and opioid medication misuse behaviors between rural and urban respondents. Multivariable statistics were used to identify risk factors associated with rural and urban opioid misuse. A total of 333 participants completed the survey. Participants in rural settings had poorer overall health, higher pain levels, lower education, and a higher rate of unemployment compared to patients in urban pharmacies. Rural respondents with illicit drug use (adjustable odds ratio [aOR]: 14.34, 95% confidence interval [CI] = 2.16-95.38), posttraumatic stress disorder (aOR: 5.44, 95% CI = 1.52-19.50), and ≤high school education (aOR: 6.68, 95% CI = 1.06-42.21) had increased risk for opioid misuse. Community pharmacy represents a promising resource for potential identification of opioid misuse, particularly in rural communities. Continued research must extend these findings and work to establish collaborative services in rural settings.

    The number of crew members in commercial flights has decreased to two members, down from the five-member crew required 50 years ago. One question of interest is whether the crew should be reduced to one pilot. In order to determine the critical factors involved in safely transitioning to a single pilot, research must examine whether any performance deficits arise with the loss of a crew member. With a concrete understanding of the cognitive and behavioral role of a co-pilot, aeronautical technologies and procedures can be developed that make up for the removal of the second aircrew member. The current project describes a pre-study walkthrough process that can be used to help in the development of scenarios for testing future concepts and technologies for single pilot operations. Qualitative information regarding the tasks performed by the pilots can be extracted with this technique and adapted for future investigations of single pilot operations.

    A research program the general objective of which was to measure the effects of various sustained accelerations on the control performance of pilots, was carried out on the Aviation Medical Acceleration Laboratory centrifuge, U.S. Naval Air Development Center, Johnsville, PA. The experimental setup consisted of a flight simulator with the centrifuge in the control loop. The pilot performed his control tasks while being subjected to acceleration fields such as might be encountered by a forward-facing pilot flying an atmosphere entry vehicle. The study was divided into three phases. In one phase of the program, the pilots were subjected to a variety of sustained linear acceleration forces while controlling vehicles with several different sets of longitudinal dynamics. Here, a randomly moving target was displayed to the pilot on a cathode-ray tube. For each combination of acceleration field and vehicle dynamics, pilot tracking accuracy was measured and pilot opinion of the stability and control characteristics was recorded. Thus, information was obtained on the combined effects of complexity of control task and magnitude and direction of acceleration forces on pilot performance. These tests showed that the pilot's tracking performance deteriorated markedly at accelerations greater than about 4g when controlling a lightly damped vehicle. The tentative conclusion was also reached that regardless of the airframe dynamics involved, the pilot feels that in order to have the same level of control over the vehicle, an increase in the vehicle dynamic stability was required with increases in the magnitudes of the acceleration impressed upon the pilot. In another phase, boundaries of human tolerance of acceleration were established for acceleration fields such as might be encountered by a pilot flying an orbital vehicle. A special pilot restraint system was developed to increase human tolerance to longitudinal decelerations. The results of the tests showed that human tolerance

    To assess the feasibility of conducting a randomized trial comparing two strategies [physician (MD) vs. non-physician (non-MD)] for approaching substitute decision makers (SDMs) for research and to evaluate SDMs' experiences in being approached for consent. A pilot mixed methods study of first encounters with SDMs. Of 137 SDMs (162 eligibility events), 67 and 70 were randomized to MD and non-MD introductions, respectively. Eighty SDMs (98 events) provided consent and 21 SDMs (24 events) declined consent for studies, including 2 SDMs who provided and declined consent. We identified few missed introductions [4/52 (7.7 %)] and protocol violations [6/117 (5.1 %)], high comfort, satisfaction and acceptance scores and similar consent rates in both arms. SDMs provided consent significantly more often when a patient update was provided in the MD arm. Most SDMs (85.7 %) felt that physician involvement was inconsequential and preferred physician time to be dedicated to patient care; however, SDM experiences were closely related to their recall of being approached and recall was poor. SDMs highlighted 7 themes of importance to them in research surrogate decision-making. SDMs prioritized the personal attributes of the person approaching them over professional designation and preferred physician time to be dedicated to patient care. A mixed methods design evaluated intervention fidelity and provided the rationale for not proceeding to a larger trial, despite achieving all feasibility metrics in the pilot trial. NCT01232621.

    Full Text Available Bullying in school, being a serious threat to physical and emotional health of children and adolescents all over the world, represents an important public health issue. In Italy, since 2007, the Italian Ministry of Education promotes activities to fight against and to prevent bullying in schools of all levels and, at the same time, also Health Authorities are trying to implement effective social-health responses. However, to date, the lack of consistent data, from national to local level, that could help in describing the problem in a proper manner, does not allow a systematic bullying surveillance and so also measuring the effectiveness of the public health strategy that could be implemented. The Bias pilot study’s aim is to evaluate the prevalence of bullying in a sample of schools in the city of Palermo, the largest in Sicily, and to investigate its characteristics in relation to different types of school. Finally, the Bias study aim to evaluate the feasibility of alternative methods for the detection of the prevalence of bullying phenomenon in schools. Here we present the research protocol and the questionnaires that will be used.

    At the Hamburg Institute for Sex Research in Germany, a nationwide study is currently being carried out into the sexual experiences, attitudes and relationships of adults (18-75 years). The main focus of this pilot study is to test the comprehensibility and length of a data collecting instrument as well as the comparison of two data collecting methods with regard to reliability and representativeness of the results as well as of the refusal rate. To this end face-to-face interviews (n = 500) and questionnaires sent by post (n = 500) are to be compared with each other as methods. The data to be collected relates to sexuality, particularly the prevention of HIV and other sexually transmitted infections (STIs). The WHO definition of sexual health forms the basis for the study and thus connects up with the existing sex survey research in Europe and western industrial nations. Comparable surveys have been conducted over the past ten years in more than 30 European countries using a variety of methods. The focus of the study is placed upon the increase that has been observed for several years now in certain STIs. The article provides an overview of existing sex survey research in Europe. It becomes clear that the studies conducted so far are very heterogeneous with regard to chosen method, sampling techniques and the choice of content focus, so that no suitable data for cross-national comparability are currently available.

    CFFTP Pilot is representative of a class of machines that, like NPD in the CANDU development program, could test the key reactor core technologies on an integrated power reactor relevant system (materials, conditions, configuration). But in order to reduce costs, the machine would operate at reduced neutron flux relative to a power reactor, would not produce electricity, and would not test superconducting magnets. This design shows research directions towards a machine that could provide integrated nuclear testing (but not ignition physics) at a cost of about 1/3 ITER CDA. The test volume - the outboard blanket volume - would be comparable to the test port volume on ITER CDA, while the fluence and power density would be about 1/4 ITER CDA. 91 refs., 43 tabs., 45 figs

    Research suggests that participants do not always adequately understand studies. While some consent interventions increase understanding, methodologic challenges have been raised in studying consent outside of actual trial settings. This study examined the feasibility of testing two consent interventions in actual studies and measured effectiveness of interventions in improving understanding. Participants enrolling in any of eight ongoing clinical trials were sequentially assigned to one of three different informed consent strategies for enrollment in their clinical trial. Control participants received standard consent procedures for their trial. Participants in the first intervention arm received a bulleted fact sheet summarizing key study information. Participants in the second intervention arm received the bulleted fact sheet and also engaged in a feedback Q&A session. Later, patients answered closed- and open-ended questions to assess patient understanding and literacy. Descriptive statistics, Wilcoxon -Mann -Whitney and Kruskal-Wallis tests were generated to assess correlations; regression analysis determined predictors of understanding. 144 participants enrolled. Using regression analysis, participants receiving the second intervention scored 7.6 percentage points higher (p = .02) on open-ended questions about understanding than participants in the control, although unadjusted comparisons did not reach statistical significance. Our study supports the hypothesis that patients receiving both bulleted fact sheets and a Q&A session had higher understanding compared to standard consent. Fact sheets and short structured dialog are quick to administer and easy to replicate across studies and should be tested in larger samples. © The Author(s) 2014.

    1981/1982. Richard E. Gray was born March 11, 1945 in Newport News, Virginia; he died on November 8, 1982 at Edwards, California, in a T-37 spin accident. The Ames-Dryden-1 (AD-1) aircraft was designed to investigate the concept of an oblique (pivoting) wing. The wing could be rotated on its center pivot, so that it could be set at its most efficient angle for the speed at which the aircraft was flying. NASA Ames Research Center Aeronautical Engineer Robert T. Jones conceived the idea of an oblique wing. His wind tunnel studies at Ames (Moffett Field, CA) indicated that an oblique wing design on a supersonic transport might achieve twice the fuel economy of an aircraft with conventional wings. The oblique wing on the AD-1 pivoted about the fuselage, remaining perpendicular to it during slow flight and rotating to angles of up to 60 degrees as aircraft speed increased. Analytical and wind tunnel studiesthat Jones conducted at Ames indicated that a transport-sized oblique-wing aircraft flying at speeds of up to Mach 1.4 (1.4 times the speed of sound) would have substantially better aerodynamic performance than aircraft with conventional wings. The AD-1 structure allowed the project to complete all of its technical objectives. The type of low-speed, low-cost vehicle - as expected - exhibited aeroelastic and pitch-roll-coupling effects that contributed to poor handling at sweep angles above 45 degrees. The fiberglass structure limited the wing stiffness that would have improved the handling qualities. Thus, after completion of the AD-1 project, there was still a need for a transonic oblique-wing research aircraft to assess the effects of compressibility, evaluate a more representative structure, and analyze flight performance at transonic speeds (those on either side of the speed of sound). The aircraft was delivered to the Dryden Flight Research Center, Edwards, CA, in March 1979 and its first flight was on December 21, 1979. Piloting the aircraft on that flight, as well

    Collaborations between scientists, care providers, and technology industry professionals are becoming more relevant for developing, testing, and implementing behavioral health technologies. As the need for such partnerships increases, it is important to understand stakeholders' attitudes about their role in partnering for developing such technologies and how much do they expect technology to impact behavioral research and care. The aim of this study was to investigate how much technology disruption do stakeholders expect in healthcare, as well as their perceived contribution in partnering for developing behavioral health technologies. Stakeholders (N = 74) responded to an online convenience sampling survey. Over 89% of participants reported expecting that technology will bring at least a moderate amount of disruption in the current models of behavioral healthcare, with respondents with the most experience in digital health expecting the most disruption. As for their perception of each other's role in partnering for developing behavioral health technologies, one group's weakness was considered to be complemented by another group's strength. Academics were perceived as having more theoretical and research expertise but being less technology-savvy, while industry professionals were considered to excel at technological and marketing activities. Providers were considered to have the most clinical and real-world healthcare industry expertise. Our results indicate that technology is expected to disrupt current healthcare models, while also highlighting the need for collaboration, as no single group was considered to have sufficient expertise and resources to develop successful, effective behavioral health technologies on its own. These results may contribute to a better understanding of how technology disruption is affecting behavioral healthcare from the standpoint of its key players, which may lead to better collaborative models of research and care delivery.

    Woodsmoke pollution is an environmental justice issue for youth living in certain Pacific Northwest cities. Participatory methods such as Citizen Science and Photovoice are effective ways to involve youth in environmental justice research. Little is understood about how youth may be empowered to address woodsmoke issues in their communities. We examined youth empowerment in a citizen science study on woodsmoke, using Photovoice methodology. Ten diverse youth collected and analyzed indoor air samples and photos, then presented their findings to the community and policy makers. Entrance and exit surveys revealed an increased sense of empowerment to take action on woodsmoke pollution. Youth also expressed increased optimism and a resolve to become scientists to combat environmental injustices.

    The 360 Degree Evaluation Model is one means to provide a comprehensive view of clinical competency and readiness for progression in an online nursing program. This pilot project aimed to evaluate the effectiveness of implementing a 360 Degree Evaluation of clinical competency of graduate advanced practice nursing students. The 360 Degree Evaluation, adapted from corporate industry, encompasses assessment of student knowledge, skills, behaviors and attitudes and validates student's progression from novice to competent. Cohort of advanced practice nursing students in four progressive clinical semesters. Graduate advanced practice nursing students (N = 54). Descriptive statistics and Jonckheere's Trend Test were used to evaluate OSCE's scores from graded rubric, standardized patient survey scores, student reflection and preceptor evaluation. We identified all students passed the four OSCEs during a first attempt or second attempt. Scaffolding OSCE's over time allowed faculty to identify cohort weakness and create subsequent learning opportunities. Standardized patients' evaluation of the students' performance in the domains of knowledge, skills and attitudes, showed high scores of 96% in all OSCEs. Students' self-reflection comments were a mix of strengths and weaknesses in their self-evaluation, demonstrating themes as students progressed. Preceptor evaluation scores revealed the largest increase in knowledge and learning skills (NONPF domain 1), from an aggregate average of 90% in the first clinical course, to an average of 95%. The 360 Degree Evaluation Model provided a comprehensive evaluation of the student and critical information for the faculty ensuring individual student and cohort data and ability to analyze cohort themes.

    The analytic performance of a low-cost, research-stage DNA test for the most carcinogenic human papillomavirus (HPV) genotypes (HPV16, HPV18, and HPV45) in aggregate was evaluated among carcinogenic HPV-positive women, which might be used to decide who needs immediate colposcopy in low-resource settings ("triage test"). We found that HPV16/18/45 test agreed well with two DNA tests, a GP5+/6+ genotyping assay (Kappa = 0.77) and a quantitative PCR assay (at a cutpoint of 5000 viral copies) (Kappa = 0.87). DNA sequencing on a subset of 16 HPV16/18/45 positive and 16 HPV16/18/45 negative verified the analytic specificity of the research test. It is concluded that the HPV16/18/45 assay is a promising triage test with a minimum detection of approximately 5000 viral copies, the clinically relevant threshold. Published by Elsevier B.V.

    There is significant inter-observer variation amongst the neuro-pathologists in the typing, subtyping, and grading of glial neoplasms for diagnosis. Centralized pathology review has been proposed to minimize this inter-observer variation and is now almost mandatory for accrual into multicentric trials. We sought to assess the concordance between neuro-pathologists on histopathological diagnosis of glioblastoma. Comparison of local, institutional, and central neuro-oncopathology reporting in a cohort of 34 patients with newly diagnosed supratentorial glioblastoma accrued consecutively at a tertiary-care institution on a prospective trial testing the addition of a new agent to standard chemo-radiation regimen. Concordance was sub-optimal between local histological diagnosis and central review, fair between local diagnosis and institutional review, and good between institutional and central review, with respect to histological typing/subtyping. Twelve (39%) of 31 patients with local histological diagnosis had identical tumor type, subtype and grade on central review. Overall agreement was modestly better (52%) between local diagnosis and institutional review. In contrast, 28 (83%) of 34 patients had completely concordant histopathologic diagnosis between institutional and central review. The inter-observer reliability test showed poor agreement between local and central review (kappa statistic=0.12, 95% confidence interval (CI): -0.03-0.32, P=0.043), but moderate agreement between institutional and central review (kappa statistic=0.51, 95%CI: 0.17-0.84, P=0.00003). Agreement between local diagnosis and institutional review was fair. There exists significant inter-observer variation regarding histopathological diagnosis of glioblastoma with significant implications for clinical research and practice. There is a need for more objective, quantitative, robust, and reproducible criteria for better subtyping for accurate diagnosis.

    Full Text Available Informed consent forms (ICFs for oncology clinical trials have grown increasingly longer and more complex. We evaluated objective understanding of critical components of informed consent among patients enrolling in contemporary trials of conventional or novel biologic/targeted therapies.We evaluated ICFs for cancer clinical trials for length and readability, and patients registered on those studies were asked to complete a validated 14-question survey assessing their understanding of key characteristics of the trial. Mean scores were compared in groups defined by trial and patient characteristics.Fifty patients, of whom half participated in trials of immunotherapy or biologic/targeted agents and half in trials of conventional therapy, completed the survey. On average, ICFs for industry-originated trials (N = 9 trials were significantly longer (P < .0001 and had lower Flesch ease-of-reading scores (P = .003 than investigator-initiated trials (N = 11. At least 80% of patients incorrectly responded to three key questions which addressed the experimental nature of their trial therapy, its purported efficacy and potential risks relative to alternative treatments. The mean objective understanding score was 76.9±8.8, but it was statistically significantly lower for patients who had not completed high school (P = .011. The scores did not differ significantly by type of cancer therapy (P = .12 or trial sponsor (P = .38.Many participants enrolled on cancer trials had poor understanding of essential elements of their trial. In order to ensure true informed consent, innovative approaches, such as expanded in-person counseling adapted to the patient's education level or cultural characteristics should be evaluated across socio-demographic groups.Clinicaltrials.gov NCT01772511.

    1977-01-01

    The oculometer is an electrooptical device designed to measure pilot scanning behavior during instrument approaches and landing operations. An overview of some results from a simulation study is presented to illustrate how information from the oculometer installed in a visual motion simulator, combined with measures of performance and control input data, can provide insight into the behavior and tactics of individual pilots during instrument approaches. Differences in measured behavior of the pilot subjects are pointed out; these differences become apparent in the way the pilots distribute their visual attention, in the amount of control activity, and in selected performance measures. Some of these measured differences have diagnostic implications, suggesting the use of the oculometer along with performance measures as a pilot training tool.

While current methods call for device provisioning, the "bring your own device" (BYOD) model permits participants to use personal phones allowing for improved patient engagement and lowered operational costs. However, more evidence is needed to demonstrate the BYOD model's feasibility in research settings. To assess if CentrosHealth, a mobile application designed to support trial compliance, produces different outcomes in medication adherence and application engagement when distributed through study-provisioned devices compared to the BYOD model. 87 participants were randomly selected to use the mobile application or no intervention for a 28-day pilot study at a 2:1 randomization ratio (2 intervention: 1 control) and asked to consume a twice-daily probiotic supplement. The application users were further randomized into two groups: receiving the application on a personal "BYOD" or study-provided smartphone. In-depth interviews were performed in a randomly-selected subset of the intervention group (five BYOD and five study-provided smartphone users). The BYOD subgroup showed significantly greater engagement than study-provided phone users, as shown by higher application use frequency and duration over the study period. The BYOD subgroup also demonstrated a significant effect of engagement on medication adherence for number of application sessions (unstandardized regression coefficient beta=0.0006, p=0.02) and time spent therein (beta=0.00001, p=0.03). Study-provided phone users showed higher initial adherence rates, but greater decline (5.7%) than BYOD users (0.9%) over the study period. In-depth interviews revealed that participants preferred the BYOD model over using study-provided devices. Results indicate that the BYOD model is feasible in health research settings and improves participant experience, calling for further BYOD model validity

    When a suspension or emulsion flows between two sacrificial metal electrodes excited by ac, the dispersed phase is consolidated and then settles. Laboratory-scale investigation of this mechanism, called electrocoagulation, and of its areas of application to water treatment were previously completed and a subsequent project was initiated to design and construct pilot-scale equipment consisting of an electrocoagulation cell, power supply, and computerized control system. The constructed pilot plant was used to test the effectiveness of electrocoagulation to clarify coal processing plant effluent. Results obtained with clay suspensions showed that flow conditions in the cell have a major effect on electric power consumption, and a reduction by a factor of three on this crucial cost parameter appeared possible compared to a previously tested batch-scale electrocoagulation system. Results obtained using the coal plant thickener feed closely duplicated those obtained with the clay mixtures. Aluminum electrode consumption, however, remained unchanged compared to the bench-scale tests. Supernatant clarity far exceeded requirements, while settling rate was too low. The settling could be speeded up by appropriate use of chemicals, but such addition affects the coagulation mechanism and reduces supernatant clarity. A tradeoff between settling rate and clarity was thus established. The total cost of treatment was deemed to be in excess of coal company requirements, but the pilot tests revealed much about the electrocoagulation system under continuous flow conditions. The technology is seen as having application in other areas such as municipal and industrial waste treatment. 22 refs., 6 figs., 2 tabs.

    1980-01-01

    A brief survey of the more dominant analysis techniques used in closed-loop handling-qualities research is presented. These techniques are shown to rely on so-called classical and modern analytical models of the human pilot which have their foundation in the analysis and design principles of feedback control. The optimal control model of the human pilot is discussed in some detail and a novel approach to the a priori selection of pertinent model parameters is discussed. Frequency domain and tracking performance data from 10 pilot-in-the-loop simulation experiments involving 3 different tasks are used to demonstrate the parameter selection technique. Finally, the utility of this modeling approach in handling-qualities research is discussed.

    Digital textbooks are increasing in popularity, often resulting from the perception that students demand the use of technology in academics. However, few studies have been done on student perceptions of digital textbooks. A pilot study was conducted with students enrolled in a nursing research course; 123 nursing students participated. This study found that students overwhelmingly preferred print textbooks over digital textbooks. More research needs to be done before assuming students would prefer digital textbooks over print.

    A pilot study is currently being carried out by ENIQ (European Network for Inspection Qualification) in order to explore the issues involved in inspection qualification applied along the general principles of the European methodology. The components selected for the pilot study are austenitic pipe to pipe and pipe to elbows welds typical of those in BWR recirculation loops. A range of defect parameters has been defined. A suitable inspection procedure designed to find the designated defects will be applied to geometrically representative test pieces. The procedure/equipment will be qualified through open trials and technical justification. The personnel qualification will be done in a blind way. Once all features of the inspection system will have been qualified an in-service inspection will be simulated in order to test the feasibility of the qualification approach followed. In this paper the current status of this pilot study is discussed. (orig.)

    Five NMIs within APMP, including CMS/ITRI, MSL, NIM, NIMT and KRISS from TCPR applied to the APMP technical committee initiative project for funding to carry out a pilot comparison of transmittance haze in 2012. The project started in 2014 and the final report was completed at the end of 2016. In this pilot comparison, three different haze standards were adopted, and transmittance haze for each standard was measured according to ASTM D1003 or ISO 14782. This paper presents the first results of an APMP pilot study of transmittance haze and the analysis of the variation among different haze measurement systems which are commonly used. The study shows that the variables such as sphere multiplier, transmittance distribution, fluorescence of samples and optical path of the incident beam cause discrepancies among NMIs and highlight deficiencies in current documentary standards.

    Many of the nation's estuaries have been environmentally stressed since the turn of the 20th century and will continue to be impacted in the future. Tampa Bay, one the Gulf of Mexico's largest estuaries, exemplifies the threats that our estuaries face (EPA Report 2001, Tampa Bay Estuary Program-Comprehensive Conservation and Management Plan (TBEP-CCMP)). More than 2 million people live in the Tampa Bay watershed, and the population constitutes to grow. Demand for freshwater resources, conversion of undeveloped areas to resident and industrial uses, increases in storm-water runoff, and increased air pollution from urban and industrial sources are some of the known human activities that impact Tampa Bay. Beginning on 2001, additional anthropogenic modifications began in Tampa Bat including construction of an underwater gas pipeline and a desalinization plant, expansion of existing ports, and increased freshwater withdrawal from three major tributaries to the bay. In January of 2001, the Tampa Bay Estuary Program (TBEP) and its partners identifies a critical need for participation from the U.S. Geological Survey (USGS) in providing multidisciplinary expertise and a regional-scale, integrated science approach to address complex scientific research issue and critical scientific information gaps that are necessary for continued restoration and preservation of Tampa Bay. Tampa Bay stakeholders identified several critical science gaps for which USGS expertise was needed (Yates et al. 2001). These critical science gaps fall under four topical categories (or system components): 1) water and sediment quality, 2) hydrodynamics, 3) geology and geomorphology, and 4) ecosystem structure and function. Scientists and resource managers participating in Tampa Bay studies recognize that it is no longer sufficient to simply examine each of these estuarine system components individually, Rather, the interrelation among system components must be understood to develop conceptual and

    2010-07-01

    Full Text Available Abstract Background In 2004, a review of pilot studies published in seven major medical journals during 2000-01 recommended that the statistical analysis of such studies should be either mainly descriptive or focus on sample size estimation, while results from hypothesis testing must be interpreted with caution. We revisited these journals to see whether the subsequent recommendations have changed the practice of reporting pilot studies. We also conducted a survey to identify the methodological components in registered research studies which are described as 'pilot' or 'feasibility' studies. We extended this survey to grant-awarding bodies and editors of medical journals to discover their policies regarding the function and reporting of pilot studies. Methods Papers from 2007-08 in seven medical journals were screened to retrieve published pilot studies. Reports of registered and completed studies on the UK Clinical Research Network (UKCRN Portfolio database were retrieved and scrutinized. Guidance on the conduct and reporting of pilot studies was retrieved from the websites of three grant giving bodies and seven journal editors were canvassed. Results 54 pilot or feasibility studies published in 2007-8 were found, of which 26 (48% were pilot studies of interventions and the remainder feasibility studies. The majority incorporated hypothesis-testing (81%, a control arm (69% and a randomization procedure (62%. Most (81% pointed towards the need for further research. Only 8 out of 90 pilot studies identified by the earlier review led to subsequent main studies. Twelve studies which were interventional pilot/feasibility studies and which included testing of some component of the research process were identified through the UKCRN Portfolio database. There was no clear distinction in use of the terms 'pilot' and 'feasibility'. Five journal editors replied to our entreaty. In general they were loathe to publish studies described as 'pilot'.

    Formerly incarcerated adults are impoverished, have high rates of substance use disorders, and have long histories of imprisonment. This article describes the development of a peer mentoring program for formerly incarcerated adults and the pilot study designed to evaluate it. The research team, which included formerly incarcerated adults and academic researchers, developed the peer mentoring program to support formerly incarcerated adults' transition to the community after prison. The purposes of the pilot evaluation study were to (1) assess the feasibility of implementing a peer-based intervention for recently released men developed using a community-based participatory research (CBPR) approach; (2) establish preliminary data on the program's impact on coping, self-esteem, abstinence self-efficacy, social support, and participation in 12-step meetings; and (3) establish a CBPR team of formerly incarcerated adults and academic researchers to develop, implement, and test interventions for this population. This pilot evaluation study employed a mixed-methods approach with a single group pretest/posttest design with 20 men on parole released from prison within the last 30 days. Quantitative findings showed significant improvement on two abstinence self-efficacy subscales, negative affect and habitual craving. Qualitative findings revealed the relevance and acceptance of peer mentoring for this population. This study demonstrated the feasibility and import of involving formerly incarcerated adults in the design, implementation, and testing of interventions intended to support their reintegration efforts.

    The Government White Paper Saving Lives: Our Healthier Nation (1999) provides a clear indication that accidents are a serious public health problem and have been targeted by the Department of Health as a key area for prevention over the next 10 years. School-based injury prevention programmes have been identified as one of the key settings for the implementation of the White Paper's heath promotion strategies. The Citizen Safety Project (CSP) is a peer-delivered injury prevention programme for Year 10 students (14-15 years) and Year 2 pupils (6-7 years). This paper summarizes the findings of a pilot study that assessed the feasibility of implementing the CSP in schools and of conducting a larger study. Working as part of their Personal Social Health Education lessons, 11 pairs (n = 22) of Year 10 students developed a project to take one accident prevention theme of their choice into a primary school to teach small groups of five or six Year 2 pupils (n = 55). A formative evaluation was conducted, based on interviews with Year 2 and Year 10 teachers (n = 2), and the diaries of Year 10 students. Knowledge of accident prevention and risk awareness was measured in Year 2 pupils using the Draw and Write technique, and impact on Year 10 students was measured using self-esteem and locus of control inventories. Using both statistical and thematic analysis the study concludes that the CSP is well accepted, improves knowledge in Year 2 pupils and boosts confidence in Year 10 students, while concurrently achieving key stage attainment targets. Implications of the study are discussed in terms of future research, as are recommendations with regard to modifications to the project.

    2006-12-01

    The results of a pilot study to assess the risk from tsunamis for the Seaside-Gearhart, Oregon region will be presented. To determine the risk from tsunamis, it is first necessary to establish the hazard or probability that a tsunami of a particular magnitude will occur within a certain period of time. Tsunami inundation maps that provide 100-year and 500-year probabilistic tsunami wave height contours for the Seaside-Gearhart, Oregon, region were developed as part of an interagency Tsunami Pilot Study(1). These maps provided the probability of the tsunami hazard. The next step in determining risk is to determine the vulnerability or degree of loss resulting from the occurrence of tsunamis due to exposure and fragility. The tsunami vulnerability assessment methodology used in this study was developed by M. Papathoma and others(2). This model incorporates multiple factors (e.g. parameters related to the natural and built environments and socio-demographics) that contribute to tsunami vulnerability. Data provided with FEMA's HAZUS loss estimation software and Clatsop County, Oregon, tax assessment data were used as input to the model. The results, presented within a geographic information system, reveal the percentage of buildings in need of reinforcement and the population density in different inundation depth zones. These results can be used for tsunami mitigation, local planning, and for determining post-tsunami disaster response by emergency services.

    Illicit trafficking and inadvertent movement of nuclear and other radioactive materials is not a new phenomenon. However, concern about such activities has increased remarkably in the last decade. Although the number of such incidents has risen, the overall extent of the problem is not restricted to Europe and not to nuclear proliferation. A few percent of these incidents involve so-called 'special nuclear materials', which may be used for nuclear weapons and therefore cause a threat of nuclear proliferation. The vast majority of these incidents, however, involve radioactive sources, low-enriched, natural or depleted uranium, which are not usable for weapons. There have been instances in which loss of control over radioactive materials has led to serious, even fatal, consequences to persons. Examples include unintentional incorporation of radioactive materials into recycled steel, recovery of lost radioactive sources by unsuspecting individuals, and deliberate purloining of radioactive material. The ITRAP project - financed by the Austrian Government and executed by the Austrian Research Center in close cooperation with the IAEA, World Customs Organisation (WCO) and Interpol - aimed at finding international consensus on specifications for detection equipment and instrumentation as well as verification of such specifications in laboratory tests and field installations. Under the umbrella of the pilot study, 23 international companies participated in the study and many of them devised improvements of their monitoring equipment. An important element of this study was the harmonized establishment of detection thresholds for practical implementation at borders or similar checkpoints. However, equally important was the verification of agreed specifications in controlled laboratory conditions and in realistic operating environments (field tests). All crucial parameters, as inter alia the false alarm rate, were verified by a significant testing effort as compared to

    Educators are integrating new technology into medical curriculum. The impact of newer technology on educational outcomes remains unclear. We aimed to determine if two pilot interventions, (1) introducing iPads into problem-based learning (PBL) sessions and (2) online tutoring would improve the educational experience of our learners. We voluntarily assigned 26 second-year medical students to iPad-based PBL sessions. Five students were assigned to Skype for exam remediation. We performed a mixed-method evaluation to determine efficacy. Pilot 1: Seventeen students completed a survey following their use of an iPad during the second-year PBL curriculum. Students noted the iPad allows for researching information in real time, annotating lecture notes, and viewing sharper images. Data indicate that iPads have value in medical education and are a positive addition to the curriculum. Pilot 2: Students agreed that online tutoring is at least or more effective than in-person tutoring. In our pilot studies, students experienced that iPads and Skype are beneficial in medical education and can be successfully employed in areas such as PBL and remediation. Educators should continue to further examine innovative opportunities for introducing technology into medical education. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    2012-07-01

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

    2005-01-01

    Maintenance Rule (MR), which was developed to monitor the effectiveness of maintenance in a nuclear power plant (NPP), has been received as highly successful program by and large since its implementation in 1996 in the United States. Korea has initiated two pilot programs to implement the Maintenance Rule program in 2003. Selected plants for the pilot implementation are Kori 3 and 4 units and Ulchin 3 and 4 units, where Kori 3 and 4 units are Westinghouse units and Ulchin 3 and 4 units are Korean Standardized Nuclear Power (KSNP) Plant units. This paper describes the results of each key tasks completed to date and insights gained from pilot study on the KSNP units. Currently, Scoping of the functions of maintenance rule and determination of safety significance level have been completed during first year. As first task, total 607 functions were identified and defined by detailed function analysis on 135 systems that cover all plant systems. About 55% of total functions are selected as within the scope of maintenance rule. Among these inscoped functions, 56% of scoped functions are safety related and 44% are non-safety related functions. Evaluation of safety significance for each function was determined by expert panel consist of eight experts in field of plant maintenance, operation, PSA, work schedule and system engineers. As a result, about 46% of functions were determined to be high safety significant functions and rest of the functions were classified as low safety significant. The remaining tasks that are included determination of performance criteria and preparation of implementing guideline will be performed in following years

  5. Epidemiologic studies of pilots and aircrew.

    During flight, pilots and cabin crew are exposed to increased levels of cosmic radiation which consists primarily of neutrons and gamma rays. Neutron dosimetry is not straightforward, but typical annual effective doses are estimated to range between two and five mSv. Higher dose rates are experienced at the highest altitudes and in the polar regions. Mean doses have been increasing over time as longer flights at higher altitudes have become more frequent. Because there are so few populations exposed to neutrons, studies of airline personnel are of particular interest. However, because the cumulative radiation exposure is so low, statistical power is a major concern. Further, finding an appropriate comparison group is problematic due to selection into these occupations and a number of biases are possible. For example, increased rates of breast cancer among flight attendants have been attributed to reproductive factors such as nulliparity and increased rates of melanoma among pilots have been attributed to excessive sun exposure during leisure time activities. Epidemiologic studies conducted over the last 20 y provide little consistent evidence linking cancer with radiation exposures from air travel.

    The Idaho National Engineering Laboratory (INEL) is developing new methods to produce high-density aggregate (artificial rock) primarily consisting of depleted uranium oxide. The objective is to develop a low-cost method whereby uranium oxide powder (UO[sub 2], U[sub 3]O[sub ]8, or UO[sub 3]) can be processed to produce high-density aggregate pieces (DU-AGG) having physical properties suitable for disposal in low-level radioactive disposal facilities or for use as a component of high-density concrete used as shielding for radioactive materials. A commercial company, G-M Systems, conducted a design study for a manufacturing pilot plant to process DU-AGG. The results of that study are included and summarized in this report. Also explained are design considerations, equipment capacities, the equipment list, system operation, layout of equipment in the plant, cost estimates, and the proposed plan and schedule

    This pilot study project explored the problem of providing access to the nomadic worker who desires to connect a computer through network access points at a number of different locations within the SNL/NM campus as well as outside the campus. The design and prototype development gathered knowledge that may allow a design to be developed that could be extended to a larger number of SNL/NM network drop boxes. The focus was to provide a capability for a worker to access the SNL IRN from a network drop box (e.g. in a conference room) as easily as when accessing the computer network from the office normally used by the worker. Additional study was done on new methods to authenticate the off campus worker, and protect and control access to data.

    A collaborative project was initiated in Norway between a university college and a hospital in order to improve RNs' and nursing students' research utilization in clinical placements. This paper describes the model (CMBP) that was developed, its first application, and evaluation. The evaluation aimed at describing nurses' and students' experiences of the CMBP related to collaboration, facilitation, learning, and impact on nursing care. Thirty-eight students from the second and third year of nursing education, and four nurses answered questionnaires with closed and open ended questions. In addition two of the nurses wrote diaries. Data were subjected to qualitative and quantitative analysis. Almost all participants reported that collaboration between nursing college and nursing practice had been beneficial. Most students and all nurses reported about valuable learning, increased understanding of research utilization, and improved quality of nursing care. Both students and RNs recommended the CMBP to be used in all clinical placements to support academic learning and increase research utilization in clinical practice. Despite study limitations the findings indicate that the CMBP has a potential to be a useful model for teaching RNs' and students EBP. However, further refinement of the model is needed, followed by a more comprehensive implementation and evaluation. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Airline pilots may be at increased risk of venous thromboembolism (VTE) because air travel has recently been established as a risk factor for VTE. The aim of this study was to assess the risk of VTE in a cohort of Dutch airline pilots. Airline pilots who had been active members of the Dutch aviation society (VNV) were questioned for the occurrence of VTE, presence of risk factors for VTE and number of flight hours per year and rank. Incidence rates among pilots were compared with those of the general Dutch population and with a population of frequently flying employees of multinational organizations. A total of 2630 male pilots were followed-up for a total of 20420 person-years (py). Six venous thromboses were reported, yielding an incidence rate of 0.3 per 1000 py. The standardized morbidity ratio, comparing these pilots with the general Dutch population adjusted for age, was 0.8. Compared with the international employee cohort, the standardized morbidity ratio was 0.7 when all employees were included and 0.6 when only the frequently travelling employees were included. The incidence rate did not increase with number of flight hours per year and did not clearly vary by rank. We conclude that the risk of VTE is not increased amongst airline pilots. © 2014 International Society on Thrombosis and Haemostasis.

  10. Pilot Research as Advocacy: The Case of Sayana Press in Kinshasa, Democratic Republic of the Congo

    ABSTRACT In the Democratic Republic of the Congo (DRC), the Ministry of Health authorizes only physicians and nurses to give injections, with one exception—medical and nursing students may also give injections if supervised by a clinical instructor. The emergence of the injectable contraceptive Sayana Press in some African countries prompted the DRC to test the acceptability and feasibility of distributing Sayana Press and other contraceptive methods at the community level through medical and nursing students. Sayana Press is similar in formulation to the injectable contraceptive Depo-Provera but contains a lower dose and is administered subcutaneously using a single-use syringe with a short needle called the Uniject system. The Uniject system allows Sayana Press to be administered by community health workers without clinical training or by self-injection. In this pilot, the advocacy objective was to obtain approval from the Ministry of Health to allow medical and nursing students to inject Sayana Press, as a first step toward authorization for community health workers to provide the method. The pilot described in this article documents a process whereby an innovative approach moved from concept to implementation to replication in less than 2 years. It also paved the way for testing additional progressive strategies to increase access to contraception at the community level. Because the pilot project included a research component designed to assess benefits and challenges, it provided the means to introduce the new task-shifting approach, which might not have been approved otherwise. Key pilot activities included: (1) increasing awareness of Sayana Press among family planning stakeholders at a national conference on family planning, (2) enlisting the support of key decision makers in designing the pilot, (3) obtaining marketing authorization to distribute Sayana Press in the DRC, (4) implementing the pilot from July to December 2015, (5) conducting quantitative

    Full Text Available We describe a framework for defining pilot and feasibility studies focusing on studies conducted in preparation for a randomised controlled trial. To develop the framework, we undertook a Delphi survey; ran an open meeting at a trial methodology conference; conducted a review of definitions outside the health research context; consulted experts at an international consensus meeting; and reviewed 27 empirical pilot or feasibility studies. We initially adopted mutually exclusive definitions of pilot and feasibility studies. However, some Delphi survey respondents and the majority of open meeting attendees disagreed with the idea of mutually exclusive definitions. Their viewpoint was supported by definitions outside the health research context, the use of the terms 'pilot' and 'feasibility' in the literature, and participants at the international consensus meeting. In our framework, pilot studies are a subset of feasibility studies, rather than the two being mutually exclusive. A feasibility study asks whether something can be done, should we proceed with it, and if so, how. A pilot study asks the same questions but also has a specific design feature: in a pilot study a future study, or part of a future study, is conducted on a smaller scale. We suggest that to facilitate their identification, these studies should be clearly identified using the terms 'feasibility' or 'pilot' as appropriate. This should include feasibility studies that are largely qualitative; we found these difficult to identify in electronic searches because researchers rarely used the term 'feasibility' in the title or abstract of such studies. Investigators should also report appropriate objectives and methods related to feasibility; and give clear confirmation that their study is in preparation for a future randomised controlled trial designed to assess the effect of an intervention.

    Despite the growing popularity of mixed-methods studies and considerable emphasis on the potential value of qualitative research to the trial endeavour, there remains a dearth of published studies reporting on actual contribution. This paper presents a critically reflective account of our experience of the actual value of undertaking qualitative research alongside a pilot cluster randomised controlled trial of a guided e-learning intervention for managers in an NHS Mental Health Trust to improve employee wellbeing and reduce sickness absence. For the qualitative study we undertook 36 in-depth interviews with key informants, managers and employees. We observed and took in-depth field notes of 10 meetings involving managers and employees at the Trust, and the two qualitative researchers acted as participant observers at steering committee and monthly research team meetings. We adopted a narrative methodological orientation alongside a thematic approach to data analysis, eliciting a rich account of the complexities of managing stress at work. We identified two key overarching roles played by the qualitative research: 'problematising' and 'contextualising'. Specifically, the qualitative data revealed and challenged assumptions embedded in the trial about the nature of the learning process, and exposed the slippery and contested nature of abstracted variables, on which a trial depends. The qualitative data challenged the trial's logic model, and provided a rich understanding of the context within which the trial and intervention took place. While acknowledging the ever-present tension in mixed-methods research between the requirements of quantitative research to represent the social world as abstracted variables, and the goal of qualitative research to explore and document the complexity of social phenomena, we adopted a pragmatic position that enabled us to engage with this tension in a productive and partially integrative way.

    NRPB's national survey of natural radiation exposure in homes commenced in 1982 and will run until 1984. A pilot survey was undertaken in over 100 homes for one year, using passive thermoluminescent dosemeters to measure external radiation from terrestrial and cosmic sources and passive radon dosemeters to measure the radon-222 gas concentration. A preliminary analysis of the results obtained from the pilot survey is given. The main value of the pilot survey was in providing experience and various administrative and scientific procedures have been simplified or automated for the national survey. (U.K.)

    Full Text Available Apart from the data on test reliability, the psychometric features of the TIMSS variables are not officially available. It is therefore not clear whether the TIMSS findings capture real educational trends. Being concerned with mathematics attitude, the aim of this research was to determine the psychometric values of a mathematics attitude scale derived from a student questionnaire, and, if these are appropriate, to examine the relation of mathematics attitude to gender and mathematics achievement, and search for gender differences in the applied mathematics attitude indicators. By using a sample of 89 seventh-grade students involved in a TIMSS 2003 pilot research, it revealed the following findings: (a the representativity reliability, homogeneity and validity of the applied attitude scale were acceptable, (b attitude to mathematics was related to mathematics achievement, (c gender differences in mathematics attitude were not found and (d gender differences in the applied indicators were only present for the statement "I need to do well in mathematics to get into the faculty of my choice" where males expressed a higher agreement than females.

    Full Text Available Abstract Background Adolescent idiopathic scoliosis (AIS remains the most common deforming orthopedic condition in children. Increasingly, both adults and children are seeking complementary and alternative therapy, including chiropractic treatment, for a wide variety of health concerns. The scientific evidence supporting the use chiropractic intervention is inadequate. The purpose of this study was to conduct a pilot study and explore issues of safety, patient recruitment and compliance, treatment standardization, sham treatment refinement, inter-professional cooperation, quality assurance, and outcome measure selection. Methods Six patients participated in this 6-month study, 5 of whom were female. One female was braced. The mean age of these patients was 14 years, and the mean Cobb angle was 22.2 degrees. The study design was a randomized controlled clinical trial with two independent and blinded observers. Three patients were treated by standard medical care (observation or brace treatment, two were treated with standard medical care plus chiropractic manipulation, and one was treated with standard medical care plus sham manipulation. The primary outcome measure was Cobb, and the psychosocial measure was Scoliosis Quality of Life Index. Results Orthopedic surgeons and chiropractors were easily recruited and worked cooperatively throughout the trial. Patient recruitment and compliance was good. Chiropractic treatments were safely employed, and research protocols were successful. Conclusion Overall, our pilot study showed the viability for a larger randomized trial. This pilot confirms the strength of existing protocols with amendments for use in a full randomized controlled trial. Trial registration This trial has been assigned an international standard randomized controlled trial number by Current Controlled Trials, Ltd. http://www.controlled-trials.com/isrctn/.

    Continuous progress is being made in new environmental technologies, such as on-line sensors, real-time wireless techniques for data transfer, remote sensing and models. Mild winters induced by climate change are presenting a challenge to traditional measures aimed at a reduction in diffuse loading. This suggests a need for the further development of environmental monitoring schemes. Lake Pyhaejaervi (154 km2) is of great importance both regionally and nationally. A large number of management measures have been applied both in the catchment and the lake itself, but more real-time, detailed data and model-based scenarios are required for water protection studies. The CatchLake project (2006- 2009) was divided into three parts: modelling, lake and catchment measurements, and remote sensing. Integrated catchment models (SWAT and INCA-N) were applied to the Ylaeneenjoki catchment, in order to simulate the suspended solids, phosphorous and nitrogen loading of the lake. The 3D process-based lake model Coherens was also applied. To validate these models, the water quality of both the lake and major rivers was measured using automatic measuring stations. More accurate estimates of the loading of the lake due to the Ylaeneenjoki river were obtained, compared to traditional, manual sampling. A custom-made flow-through method was used to collect high resolution transect datasets of water quality information from Lake Pyhaejaervi in ten measuring campaigns. Remote sensing methods were applied to retrieve spring-to-autumn time-series of spatial water quality information. Chlorofyll-a measurement of the lake float provided a better insight into the lake's state of eutrofication, as well as the strength and timing of phytoplankton blooms. The report discusses new information made available by measuring technology, remote sensing and modelling with respect to environmental research and monitoring. In addition, general conclusions and descriptions of the further use of this

    Twenty-nine urban inhabitants participated in a half-day climatotherapy programme at the moderate mountain area and lowland area in the northwest part of the main island of Japan. The current study was aimed to investigate physically and mentally the objective and subjective influence of our short programme, which was a prospective pilot study of single intervention. Blood pressure was significantly descended during terrain cure at the uphill mountain path and returned after fresh-air rest cure, while there was no significant change throughout the programme at lowland flat path. Heart rate was significantly ascended and descended at both area, and more clearly changed at the mountain path. Profile of Mood Status brief form Japanese version administered before and after our half-day programme. Age adjusted T score of negative subscales, `tension-anxiety', `depression', `anger-hostility', `fatigue' and `confusion' were significantly lower after climatotherapy at both sites. Whereas, there was no significant change concerning `vigour' score. This short-version climatotherapy programme has been designed for people without enough time for long stay at health resort. It turned out our half-day climatotherapy programme contribute to mood status improvement. In addition, repeated practice of our short-version programme including endurance exercise with cool body shell using uphill path can be expected that blood pressure will go toward the normal range and heart rate will decrease both in usual time and during exercise. Therefore, health benefits can be expected of this climatotherapy programme.

    Most of domestic alcohol fermentation factory adopt batch process of which productivity is lower than continuous fermentation process. They have made great effort to increase productivity by means of partial unit process automatization and process improvement with their accumulated experience but there is technical limitation in productivity of batch fermentation process. To produce and supply fuel alcohol, economic aspects must be considered first of all. Therefore, development of continuous fermentation process, of which productivity is high, is prerequisite to produce and use fuel alcohol but only a few foreign company possess continuous fermentation technic and use it in practical industrial scale fermentation. We constructed pilot plant (5 Stage CSTR 1 kl 99.5 v/v% ethanol/Day scale) to study some aspects stated below and our ultimate aims are production of industrial scale fuel alcohol and construction of the plant by ourselves. Some study concerned with energy saving separation and contamination control technic were entrusted to KAIST, A-ju university and KIST respectively. (author) 67 refs., 100 figs., 58 tabs.

    In-home displays, dynamic pricing, and automated devices aim to reduce residential electricity use—overall and during peak hours. We present a meta-analysis of 32 studies of the impacts of these interventions, conducted in the US or Canada. We find that methodological problems are common in the design of these studies, leading to artificially inflated results relative to what one would expect if the interventions were implemented in the general population. Particular problems include having volunteer participants who may have been especially motivated to reduce their electricity use, letting participants choose their preferred intervention, and having high attrition rates. Using estimates of bias from medical clinical trials as a guide, we recalculate impact estimates to adjust for bias, resulting in values that are often less than half of those reported in the reviewed studies. We estimate that in-home displays were the most effective intervention for reducing overall electricity use (∼4% using reported data; ∼3% after adjusting for bias), while dynamic pricing significantly reduced peak demand (∼11% reported; ∼6% adjusted), especially when used in conjunction with home automation (∼25% reported; ∼14% adjusted). We conclude with recommendations that can improve pilot studies and the soundness of decisions based on their results. -- Highlights: •We conduct a meta-analysis of field studies of in-home displays, dynamic pricing, and automation on overall and peak use. •Studies were assessed and adjusted for risk-of-bias from inadequate experimental design. •Most studies were at high risk-of-bias from multiple sources. •In-home displays provided the best overall reduction in energy use, approximately 3% after adjustment for risk-of-bias. •Even after adjustment, automation approximately doubled the effectiveness of dynamic pricing on peak reduction from 6% to 14%

    A pilot treatment study is proving to be effective for the remediation of uranium-contaminated soil from a site at the Los Alamos National Laboratory by use of a two-step, zero-discharge, 100% recycle system. Candidate uranium-contaminated soils were characterized for uranium content, uranium speciation, organic content, size fractionization, and pH. Geochemical computer codes were used to forecast possible uranium leach scenarios. Uranium contamination was not homogenous throughout the soil. In the first step, following excavation, the soil was sorted by use of the ThemoNuclean Services segmented gate system. Following the sorting, uranium-contaminated soil was remediated in a containerized vat leach process by use of sodium-bicarbonate leach solution. Leach solution containing uranium-carbonate complexes is to be treated by use of ion-exchange media and then recycled. Following the treatment process the ion exchange media will be disposed of in an approved low-level radioactive landfill. It is anticipated that treated soils will meet Department of Energy site closure guidelines, and will be given open-quotes no further actionclose quotes status. Treated soils are to be returned to the excavation site. A volume reduction of contaminated soils will successfully be achieved by the treatment process. Cost of the treatment (per cubic meter) is comparable or less than other current popular methods of uranium-contamination remediation

    Full Text Available The study was aimed at understanding the EFL Indonesian students’ perspective on the writing process. The pilot study involved two male Indonesian postgraduate students in Universiti Utara Malaysia. The Indonesian students were selected based on the following criteria: (1 had enough knowledge in English writing, indicated by the completion of Academic Writing and Research Methodology courses taken in UUM; (2 had written an unpublished thesis during their undergraduate studies in Indonesia and they are writing their master or doctoral thesis in English; (3 used English extensively in writing their assignments, and in daily activities. Pseudonyms were used to refer to the participants as Sukarno and Suharto. The data were collected through in-depth interviews with the participants. The interview sessions took approximately 15-20 minutes for each participant and were videotaped and audiotaped. Semi-structured interview with 15 questions and probes were used. The results showed that the two participants had positive feelings and attitudes towards writing in English. Although they had a hard time in English writing during their undergraduate in Indonesia, they become fond of writing in English in their postgraduate time due to the exposure to English extensively. In composing, they used brainstorming, drafting, pausing, revising and editing in a recursive manner. Keywords: in-depth interview, pilot study, writing process, English as a Foreign Language (EFL

    In a world where funding is limited, training for healthcare professionals is turning more and more to distance learning in an effort to maintain a knowledgeable and skilled work force. In 2010, Cicatelli Associates, Inc. began exploring the feasibility of using games and virtual worlds as an alternative means to teach skills-training in a distance-learning environment. The pilot study was conducted with six individuals familiar with general counseling and communication skills used by the healthcare industry to promote behavior change. Participants reported that the venue, although challenging at first, showed great potential for use with healthcare providers, as it allowed for more interaction and activities than traditional Webinars. However, there are significant limitations that must be overcome in order for this healthcare training modality to be utilized on a large scale. These limitations included a lack of microgestures and issues regarding the technology being used. In spite of the limitations, however, the potential use of virtual worlds for the training of healthcare providers exists and should be researched further. This article discusses the need and intended benefits of virtual world training as well as the results and conclusions of the pilot study.

    Since the nineties of last century research has been conducted on the development of the aerobic granular sludge technology for wastewater treatment. A first STOWA pilot research project was executed at Ede, Netherlands. In 2005 a technological breakthrough was accomplished and was the starting sign for a broader national development program (NNOP). Next to STOWA, Delft University of Delft and DHV, six Waterboards are involved within this development program. Main goal of the NNOP is to develop a new competitive biological wastewater treatment technology (Nereda). After the Ede project additional pilot research projects were conducted at four locations in the Netherlands. Within these pilot research projects the following aspects were investigated: granulation on different wastewater types; stability of granular sludge; optimization of nitrogen and phosphate removal, especially during winter time; control of effluent suspended solids concentration; and obtain technological design parameters for full scale WWTPs (waste water treatment plants) [Dutch] In dit rapport staan de resultaten beschreven van de tussen 2003 en 2010 uitgevoerde pilots met de aeroob-korrelslibtechnologie Nereda. Dit is een nieuwe zuiveringstechnologie waarbij het reinigende actief slib geen vlokken maar korrels vormt. Hierdoor bezinkt het slib sneller en makkelijker. De technologie wordt gekenmerkt door hoge zuiveringsrendementen, weinig ruimtebeslag (voor bezinking) en relatief lage energiekosten. De resultaten van de pilots zijn dermate goed, dat drie van de vijf deelnemende waterschappen hebben besloten om 1 van hun rwzi's (rioolwaterzuiveringsinstallaties) aan te passen op basis van de Nereda-technologie.

    Although large medical texts are stored in electronic format, they are seldom reused because of the difficulty of processing narrative texts by computer. Morphological analysis is a key technology for extracting medical terms correctly and automatically. This process parses a sentence into its smallest unit, the morpheme. Phrases consisting of two or more technical terms, however, cause morphological analysis software to fail in parsing the sentence and output unprocessed terms as "unknown words." The purpose of this study was to reduce the number of unknown words in medical narrative text processing. The results of parsing the text with additional dictionaries were compared with the analysis of the number of unknown words in the national examination for radiologists. The ratio of unknown words was reduced 1.0% to 0.36% by adding terminologies of radiological technology, MeSH, and ICD-10 labels. The terminology of radiological technology was the most effective resource, being reduced by 0.62%. This result clearly showed the necessity of additional dictionary selection and trends in unknown words. The potential for this investigation is to make available a large body of clinical information that would otherwise be inaccessible for applications other than manual health care review by personnel.

    Experiments on pilot decision making are described. The development of models of pilot decision making in critical in flight events (CIFE) are emphasized. The following tests are reported on the development of: (1) a frame system representation describing how pilots use their knowledge in a fault diagnosis task; (2) assessment of script norms, distance measures, and Markov models developed from computer aided testing (CAT) data; and (3) performance ranking of subject data. It is demonstrated that interactive computer aided testing either by touch CRT's or personal computers is a useful research and training device for measuring pilot information management in diagnosing system failures in simulated flight situations. Performance is dictated by knowledge of aircraft sybsystems, initial pilot structuring of the failure symptoms and efficient testing of plausible causal hypotheses.

    Cardiac auscultation is a cost-effective, noninvasive screening tool that can provide information about cardiovascular hemodynamics and disease. However, with advances in imaging and laboratory tests, the importance of cardiac auscultation is less appreciated in clinical practice. The widespread use of smartphones provides opportunities for nonmedical expert users to perform self-examination before hospital visits. The objective of our study was to assess the feasibility of cardiac auscultation using smartphones with no add-on devices for use at the prehospital stage. We performed a pilot study of patients with normal and pathologic heart sounds. Heart sounds were recorded on the skin of the chest wall using 3 smartphones: the Samsung Galaxy S5 and Galaxy S6, and the LG G3. Recorded heart sounds were processed and classified by a diagnostic algorithm using convolutional neural networks. We assessed diagnostic accuracy, as well as sensitivity, specificity, and predictive values. A total of 46 participants underwent heart sound recording. After audio file processing, 30 of 46 (65%) heart sounds were proven interpretable. Atrial fibrillation and diastolic murmur were significantly associated with failure to acquire interpretable heart sounds. The diagnostic algorithm classified the heart sounds into the correct category with high accuracy: Galaxy S5, 90% (95% CI 73%-98%); Galaxy S6, 87% (95% CI 69%-96%); and LG G3, 90% (95% CI 73%-98%). Sensitivity, specificity, positive predictive value, and negative predictive value were also acceptable for the 3 devices. Cardiac auscultation using smartphones was feasible. Discrimination using convolutional neural networks yielded high diagnostic accuracy. However, using the built-in microphones alone, the acquisition of reproducible and interpretable heart sounds was still a major challenge.

    Full Text Available Abstract Background The purpose of this study was to survey full-time faculty at a single chiropractic college concerning their knowledge of Institutional Review Board (IRB policies in their institution as they pertain to educational research. Methods All full-time faculty were invited to participate in an anonymous survey. Four scenarios involving educational research were described and respondents were asked to select from three possible courses of action for each. In addition, respondents were queried about their knowledge of IRB policies, how they learned of these policies and about their years of service and departmental assignments. Results The response rate was 55%. In no scenario did the level of correct answers by all respondents score higher than 41% and in most, the scores were closer to just under 1 in 3. Sixty-five percent of respondents indicated they were unsure whether Palmer had any policies in place at all, while 4% felt that no such policies were in place. Just over one-quarter (27% were correct in noting that students can decline consent, while more than half (54% did not know whether there were any procedures governing student consent. Conclusion Palmer faculty have only modest understanding about institutional policies regarding the IRB and human subject research, especially pertaining to educational research. The institution needs to develop methods to provide knowledge and training to faculty. The results from this pilot study will be instrumental in developing better protocols for a study designed to survey the entire chiropractic academic community.

    The aim of the research was to conduct a primary scoping study on the impact of air sealing between the foundation and the living space on radon transport reduction across the foundation-living space floor assembly. Fifteen homes in the Champaign, Illinois area participated in the study. These homes were instrumented for hourly continuous radon measurements and simultaneous temperature and humidity the foundation was improved. However, this improved isolation did not lead to significant reductions in radon concentration in the living space. Other factors such as outdoor temperature were shown to have an impact on radon concentration.

  6. EEG activity in Muslim prayer: A pilot study

    Directory of Open Access Journals (Sweden)

    Haider H. Alwasiti

    2010-12-01

    Full Text Available Almost all religions incorporate some form of meditation. Muslim prayer is the meditation of Islam. It is an obligatory prayer for all Muslims that is performed five times a day. Although a large body of literature exists on EEG changes in meditation, to date there has been no research published in a peer-reviewed journal on EEG changes during Muslim prayer. The purpose of this pilot study is to encourage further investigation on this type of meditation. Results of EEG analysis in twenty-five trials of Muslim prayer are reported. Some of the findings are consistent with the majority of the previous meditation studies (alpha rhythm slowing, increased alpha rhythm coherence. However, Muslim prayer does not show an increase in alpha and/or theta power like most of the results of other meditation studies. The possible cause of this discrepancy in meditation-related studies is highlighted and a systematic and standardised roadmap for future Muslim prayer EEG research is proposed.

    As Brain-Computer Interface (BCI) systems advance for uses such as robotic arm control it is postulated that the control paradigms could apply to other scenarios, such as control of video games, wheelchair movement or even flight. The purpose of this pilot study was to determine whether our BCI system, which involves decoding the signals of two 96-microelectrode arrays implanted into the motor cortex of a subject, could also be used to control an aircraft in a flight simulator environment. The study involved six sessions in which various parameters were modified in order to achieve the best flight control, including plane type, view, control paradigm, gains, and limits. Successful flight was determined qualitatively by evaluating the subject's ability to perform requested maneuvers, maintain flight paths, and avoid control losses such as dives, spins and crashes. By the end of the study, it was found that the subject could successfully control an aircraft. The subject could use both the jet and propeller plane with different views, adopting an intuitive control paradigm. From the subject's perspective, this was one of the most exciting and entertaining experiments she had performed in two years of research. In conclusion, this study provides a proof-of-concept that traditional motor cortex signals combined with a decoding paradigm can be used to control systems besides a robotic arm for which the decoder was developed. Aside from possible functional benefits, it also shows the potential for a new recreational activity for individuals with disabilities who are able to master BCI control.

  20. Small Business Demand Response with Communicating Thermostats: SMUD's Summer Solutions Research Pilot

    Energy Technology Data Exchange (ETDEWEB)

    Herter, Karen; Wayland, Seth; Rasin, Josh

    2009-09-25

    This report documents a field study of 78 small commercial customers in the Sacramento Municipal Utility District service territory who volunteered for an integrated energy-efficiency/demand-response (EE-DR) program in the summer of 2008. The original objective for the pilot was to provide a better understanding of demand response issues in the small commercial sector. Early findings justified a focus on offering small businesses (1) help with the energy efficiency of their buildings in exchange for occasional load shed, and (2) a portfolio of options to meet the needs of a diverse customer sector. To meet these expressed needs, the research pilot provided on-site energy efficiency advice and offered participants several program options, including the choice of either a dynamic rate or monthly payment for air-conditioning setpoint control. An analysis of hourly load data indicates that the offices and retail stores in our sample provided significant demand response, while the restaurants did not. Thermostat data provides further evidence that restaurants attempted to precool and reduce AC service during event hours, but were unable to because their air-conditioning units were undersized. On a 100 F reference day, load impacts of all participants during events averaged 14%, while load impacts of office and retail buildings (excluding restaurants) reached 20%. Overall, pilot participants including restaurants had 2007-2008 summer energy savings of 20% and bill savings of 30%. About 80% of participants said that the program met or surpassed their expectations, and three-quarters said they would probably or definitely participate again without the $120 participation incentive. These results provide evidence that energy efficiency programs, dynamic rates and load control programs can be used concurrently and effectively in the small business sector, and that communicating thermostats are a reliable tool for providing air-conditioning load shed and enhancing the ability

    Nowak, Peter

    2011-03-01

    There is a broad range qualitative linguistic research (sequential analysis) on doctor-patient interaction that had only a marginal impact on clinical research and practice. At least in parts this is due to the lack of qualitative research synthesis in the field. Available research summaries are not systematic in their methodology. This paper proposes a synthesis methodology for qualitative, sequential analytic research on doctor-patient interaction. The presented methodology is not new but specifies standard methodology of qualitative research synthesis for sequential analytic research. This pilot review synthesizes twelve studies on German-speaking doctor-patient interactions, identifies 45 verbal actions of doctors and structures them in a systematics of eight interaction components. Three interaction components ("Listening", "Asking for information", and "Giving information") seem to be central and cover two thirds of the identified action types. This pilot review demonstrates that sequential analytic research can be synthesized in a consistent and meaningful way, thus providing a more comprehensive and unbiased integration of research. Future synthesis of qualitative research in the area of health communication research is very much needed. Qualitative research synthesis can support the development of quantitative research and of educational materials in medical training and patient training. Copyright © 2011 Elsevier Ireland Ltd.

    Objective: This pilot study examined the laboratory responses of patients with laboratory-documented typhoid fever who were treated with Biomagnetic Pair Therapy (BPT; medical biomagnetism), a specific application of pairs of magnets for various ailments that are infectious and otherwise. Materials and Methods: This study was an assessment of patients' response to treatment with only BPT for Salmonella typhi infections (typhoid fever) using standard conventional laboratory techniques. The research was conducted in an outpatient village clinic in Kenya. There were 52 participants who were evaluated for possible systemic illness, including typhoid fever, from an open-label study. Participants who felt sick and requested testing for possible typhoid fever were tested with a standard Widal test by a certified laboratory technician. Participants who tested positive (13 patients) were then treated with BPT (a "First Aid" approach) only. These participants then returned for follow-up laboratory and clinical evaluations after 2 days. Results: Most of the participants (10 of 13) retested as negative, and all patients reported symptomatic clinical improvement. Conclusions: As a significant majority of participants demonstrated clearing of their S. typhi after BPT, this technique should be studied further in larger trials for its efficacy in treating typhoid fever.

    During the spring of 2016, from April 4 - May 27, sixteen GLOBE schools participated in the GLOBE Aerosol Field Campaign - U.S. Pilot Study. Thirteen teachers from these schools had previously participated in the NASA LEARN program (Long-term Experience in Authentic Research with NASA) where they were GLOBE trained in Atmosphere protocols, and engaged in 1-3 years of research under the mentorship of NASA scientists. Each school was loaned two aerosol instruments for the Campaign duration, either 2 GLOBE sun photometers, 2 Calitoo sun photometers, or 1 of each. This allowed for students to make measurements side-by-side and in the case of the Calitoos, to compare AOT results immediately with each other for better consistency in data collection. Additionally, as part of the Field Campaign evaluation, multiple instruments allow for an assessment of the ease of use of each instrument for grade level of students, whether in middle school or high school. Before the Campaign, all GLOBE and Calitoo instruments were 'checked out' against an AERONET, then checked again upon return after the Campaign. By examining all data, before, during and after the Campaign, this gives an indication of instrument performance and proficiency obtained by the students. Support was provided to each teacher and their students at the level requested, via email, phone or video conferencing.

    The Problem Solving Intervention (PSI) is a structured, cognitive-behavioral intervention that provides people with problem-solving coping skills to help them face major negative life events and daily challenges. PSI has been applied to numerous settings but remains largely unexplored in the hospice setting. The aim of this pilot study was to demonstrate the feasibility of PSI targeting informal caregivers of hospice patients. We enrolled hospice caregivers who were receiving outpatient services from two hospice agencies. The intervention included three visits by a research team member. The agenda for each visit was informed by the problem-solving theoretical framework and was customized based on the most pressing problems identified by the caregivers. We enrolled 29 caregivers. Patient's pain was the most frequently identified problem. On average, caregivers reported a higher quality of life and lower level of anxiety postintervention than at baseline. An examination of the caregiver reaction assessment showed an increase of positive esteem average and a decrease of the average value of lack of family support, impact on finances, impact on schedules, and on health. After completing the intervention, caregivers reported lower levels of anxiety, improved problem solving skills, and a reduced negative impact of caregiving. Furthermore, caregivers reported high levels of satisfaction with the intervention, perceiving it as a platform to articulate their challenges and develop a plan to address them. Findings demonstrate the value of problem solving as a psycho-educational intervention in the hospice setting and call for further research in this area.

    The U.S. Department of Energy's Building America research team Partnership for Advanced Residential Retrofits conducted a primary scoping study on the impact of air sealing between the foundation and the living space on radon transport reduction across the foundation and living space floor assembly. Fifteen homes in the Champaign, Illinois, area participated in the study. These homes were instrumented for hourly continuous radon measurements and simultaneous temperature and humidity measurements. Blower door and zone pressure diagnostics were conducted at each house. The treatments consisted of using air-sealing foams at the underside of the floor that separated the living space from the foundation and providing duct sealing on the ductwork that is situated in the foundation area. The hypothesis was that air sealing the floor system that separated the foundation from the living space should better isolate the living space from the foundation; this isolation should lead to less radon entering the living space from the foundation. If the hypothesis had been proven, retrofit energy-efficiency programs may have chosen to adopt these isolation methods for enhanced radon protection to the living space.

    2015-01-01

    Full Text Available Background. Telemedicine can be defined as the use of electronic media for transmission of information and medical data from one site to another. The objective of this study is to demonstrate an experience of telemedicine in plastic surgery. Methods. 32 plastic surgeons received a link with password for real-time streaming of a surgery. At the end of the procedure, the surgeons attending the procedure by the Internet answered five questions. The results were analyzed with descriptive statistics. Results. 27 plastic surgeons attended the online procedure in real-time. 96.3% considered the access to the website as good or excellent and 3.7% considered it bad. 14.8% reported that the transmission was bad and 85.2% considered the quality of transmission as good or excellent. 96.3% classified the live broadcasting as a good or excellent learning experience and 3.7% considered it a bad experience. 92.6% reported feeling able to perform this surgery after watching the demo and 7.4% did not feel able. 100% of participants said they would like to participate in other surgical demonstrations over the Internet. Conclusion. We conclude that the use of telemedicine can provide more access to education and medical research, for plastic surgeons looking for medical education from distant regions.

  2. Quantum Physics Principles and Communication in the Acute Healthcare Setting: A Pilot Study.

    Science.gov (United States)

    Helgeson, Heidi L; Peyerl, Colleen Kraft; Solheim-Witt, Marit

    This pilot study explores whether clinician awareness of quantum physics principles could facilitate open communication between patients and providers. In the spirit of action research, this study was conceptualized with a holistic view of human health, using a mixed method design of grounded theory as an emergent method. Instrumentation includes surveys and a focus group discussion with twelve registered nurses working in an acute care hospital setting. Findings document that the preliminary core phenomenon, energy as information, influences communication in the healthcare environment. Key emergent themes include awareness, language, validation, open communication, strategies, coherence, incoherence and power. Research participants indicate that quantum physics principles provide a language and conceptual framework for improving their awareness of communication and interactions in the healthcare environment. Implications of this pilot study support the feasibility of future research and education on awareness of quantum physics principles in other clinical settings. Copyright © 2016 Elsevier Inc.

  3. Dissolution studies with pilot plant and actual INTEC calcines

    Herbst, R.S.; Garn, T.G.

    1999-01-01

    The dissolution of Idaho Nuclear Technology and Engineering Center (INTEC) pilot plant calcines was examined to determine solubility of calcine matrix components in acidic media. Two representatives pilot plant calcine types were studied: Zirconia calcine and Zirconia/Sodium calcine. Dissolution of these calcines was evaluated using lower initial concentrations of nitric acid than used in previous tests to decrease the [H+] concentration in the final solutions. Lower [H+] concentrations contribute to more favorable TRUEX/SREX solvent extraction flowsheet performance. Dissolution and analytical results were also obtained for radioactive calcines produced using high sodium feeds blended with non-radioactive Al(NO 3 ) 3 solutions to dilute the sodium concentration and prevent bed agglomeration during the calcination process. Dissolution tests indicated >95 wt.% of the initial calcine mass can be dissolved using the baseline dissolution procedure, with the exception that higher initial nitric acid concentrations are required. The higher initial acid concentration is required for stoichiometric dissolution of the oxides, primarily aluminum oxide. Statistically designed experiments using pilot plant calcine were performed to determine the effect of mixing rate on dissolution efficiency. Mixing rate was determined to provide minimal effects on wt.% dissolution. The acid/calcine ratio and temperature were the predominate variables affecting the wt.% dissolution, a result consistent with previous studies using other similar types of pilot plant calcines

    Ambulance professionals often address conflicts between ethical values. As individuals' values represent basic convictions of what is right or good and motivate behaviour, research is needed to understand their value profiles. To translate and adapt the Managerial Values Profile to Spanish and Swedish, and measure the presence of utilitarianism, moral rights and/or social justice in ambulance professionals' value profiles in Spain and Sweden. The instrument was translated and culturally adapted. A content validity index was calculated. Pilot tests were carried out with 46 participants. This study conforms to the ethical principles for research involving human subjects and adheres to national laws and regulations concerning informed consent and confidentiality. Spanish professionals favoured justice and Swedish professionals' rights in their ambulance organizations. Both countries favoured utilitarianism least. Gender differences across countries showed that males favoured rights. Spanish female professionals favoured justice most strongly of all. Swedes favour rights while Spaniards favour justice. Both contexts scored low on utilitarianism focusing on total population effect, preferring the opposite, individualized approach of the rights and justice perspectives. Organizational investment in a utilitarian perspective might jeopardize ambulance professionals' moral right to make individual assessments based on the needs of the patient at hand. Utilitarianism and a caring ethos appear as stark opposites. However, a caring ethos in its turn might well involve unreasonable demands on the individual carer's professional role. Since both the justice and rights perspectives portrayed in the survey mainly concern relationship to the organization and peers within the organization, this relationship might at worst be given priority over the equal treatment and moral rights of the patient. A balanced view on ethical perspectives is needed to make professionals observant and

    2014-01-01

    Full Text Available Background: Harm ratings of substances help in understanding the perception toward substance use and formulating policies. Evidence of such harm ratings by substance users and their caregivers provides a clearer perspective of those who experience and observe such harm closely. Materials and Methods: Substance users and their caregivers were recruited from the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh. Sociodemographic details of the subjects were noted. The subjects were then asked to rate a list of psychoactive preparations according to the harms they thought the preparation caused. The list of substances was developed taking into consideration substance commonly encountered in the geographical area. The harm ratings were transformed on a scale of 0-100. Results: All subjects were males and majority of them were educated above 10 th standard, were not employed and belonged to urban background. Most of them had taken psychoactive substances in their lifetimes but were currently abstinent. Most of the subjects endorsed intravenous drugs as the most harmful, followed by heroin. Beer and chewable tobacco considered the least harmful substances. Greater degree of education was associated with lower harm rankings for heroin, cannabis, dextropropoxyphene, and raw opium; while urban residence was associated with greater harm ratings for cannabis and raw opium. Differences in the harms were perceived for different preparations of the same active compound for alcohol and nicotine. Conclusion: Harm ratings of substances can be a useful guide while formulating policies and allocating resources. Need for further research extending this pilot study is emphasized.

  11. Gene Expression Correlation for Cancer Diagnosis: A Pilot Study

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Poor prognosis for late-stage, high-grade, and recurrent cancers has been motivating cancer researchers to search for more efficient biomarkers to identify the onset of cancer. Recent advances in constructing and dynamically analyzing biomolecular networks for different types of cancer have provided a promising novel strategy to detect tumorigenesis and metastasis. The observation of different biomolecular networks associated with normal and cancerous states led us to hypothesize that correlations for gene expressions could serve as valid indicators of early cancer development. In this pilot study, we tested our hypothesis by examining whether the mRNA expressions of three randomly selected cancer-related genes PIK3C3, PIM3, and PTEN were correlated during cancer progression and the correlation coefficients could be used for cancer diagnosis. Strong correlations (0.68≤r≤1.0 were observed between PIK3C3 and PIM3 in breast cancer, between PIK3C3 and PTEN in breast and ovary cancers, and between PIM3 and PTEN in breast, kidney, liver, and thyroid cancers during disease progression, implicating that the correlations for cancer network gene expressions could serve as a supplement to current clinical biomarkers, such as cancer antigens, for early cancer diagnosis.

    2017-12-01

    The aim of this pilot study was to adapt the intensive mothering ideology concept in a French sample and to get an assessment tool. First, the Intensive Parenting Attitudes Questionnaire (IPAQ), a U.S. scale comprising 25 items, was translated and submitted online to French mothers and mothers-to-be (n=250). Structural validity was tested through confirmatory factor analysis with poor results. Secondly, to increase the cultural validity of a new tool, new items were derived from French women speech. French mothers and mothers-to-be (n=22) were asked about their views regarding motherhood and childcare (semi-structured interviews). A thematic content analysis was performed with good inter-judge agreement (0.53-0.86) and 27 items were created. Finally, the total set of 52 items was submitted online to French mothers and mothers-to-be (n=474). The structure was tested through exploratory factor analysis. A new tool called the Measure of Intensive Mothering Ideology (MIMI) was obtained. This 21 items scale with 6 dimensions (Essentialism, Consuming Fulfillment, Child-centrism, Challenge, Sacrifice and Stimulation) explains 59.75% of variance. Internal consistencies were satisfactory (0.61-0.83) and most dimensions were positively and moderately correlated (0.17-0.38). The MIMI is the first French-language scale assessing IMI and offers interesting research avenues notably regarding perinatal parental adaptation. Copyright © 2017 L'Encéphale, Paris.

    2018-01-01

    Full Text Available In consideration of the situation that civil aviation accidents involve many human-error factors and show the features of typical grey systems, an index system of civil aviation accident human-error factors is built using human factor analysis and classification system model. With the data of accidents happened worldwide between 2008 and 2011, the correlation between human-error factors can be analyzed quantitatively using the method of grey relational analysis. Research results show that the order of main factors affecting pilot human-error factors is preconditions for unsafe acts, unsafe supervision, organization and unsafe acts. The factor related most closely with second-level indexes and pilot human-error factors is the physical/mental limitations of pilots, followed by supervisory violations. The relevancy between the first-level indexes and the corresponding second-level indexes and the relevancy between second-level indexes can also be analyzed quantitatively.

  16. Rare variants in ischemic stroke: an exome pilot study.

    Directory of Open Access Journals (Sweden)

    John W Cole

    Full Text Available The genetic architecture of ischemic stroke is complex and is likely to include rare or low frequency variants with high penetrance and large effect sizes. Such variants are likely to provide important insights into disease pathogenesis compared to common variants with small effect sizes. Because a significant portion of human functional variation may derive from the protein-coding portion of genes we undertook a pilot study to identify variation across the human exome (i.e., the coding exons across the entire human genome in 10 ischemic stroke cases. Our efforts focused on evaluating the feasibility and identifying the difficulties in this type of research as it applies to ischemic stroke. The cases included 8 African-Americans and 2 Caucasians selected on the basis of similar stroke subtypes and by implementing a case selection algorithm that emphasized the genetic contribution of stroke risk. Following construction of paired-end sequencing libraries, all predicted human exons in each sample were captured and sequenced. Sequencing generated an average of 25.5 million read pairs (75 bp×2 and 3.8 Gbp per sample. After passing quality filters, screening the exomes against dbSNP demonstrated an average of 2839 novel SNPs among African-Americans and 1105 among Caucasians. In an aggregate analysis, 48 genes were identified to have at least one rare variant across all stroke cases. One gene, CSN3, identified by screening our prior GWAS results in conjunction with our exome results, was found to contain an interesting coding polymorphism as well as containing excess rare variation as compared with the other genes evaluated. In conclusion, while rare coding variants may predispose to the risk of ischemic stroke, this fact has yet to be definitively proven. Our study demonstrates the complexities of such research and highlights that while exome data can be obtained, the optimal analytical methods have yet to be determined.

    1978-01-01

    A pilot model analysis was performed that relates pilot control compensation, pilot aircraft system response, and aircraft response characteristics for longitudinal control. The results show that a higher aircraft short period frequency is required to achieve superior pilot aircraft system response in an altitude control task than is required in an attitude control task. These results were confirmed by a simulation study of target tracking. It was concluded that the pilot model analysis provides a theoretical basis for determining the effect of control task on pilot opinions.

  18. Pilot research projects for underground disposal of radioactive wastes in the United States of America

    International Nuclear Information System (INIS)

    Stein, R.; Collyer, P.L.

    1984-01-01

    Disposal of commercial radioactive waste in the United States of America in a deep underground formation will ensure permanent isolation from the biosphere with minimal post-closure surveillance and maintenance. The siting, design and development, performance assessment, operation, licensing, certification and decommissioning of an underground repository have stimulated the development of several pilot research projects throughout the country. These pilot tests and projects, along with their resulting data base, are viewed as important steps in the overall location and construction of a repository. Beginning in the 1960s, research at pilot facilities has progressed from underground spent fuel tests in an abandoned salt mine to the production of vitrified nuclear waste in complex borosilicate glass logs. Simulated underground repository experiments have been performed in the dense basalts of Washington State, the volcanic tuffaceous rock of Nevada and both domal and bedded salts of Louisiana and Kansas. In addition to underground pilot in situ tests, other facilities have been constructed or modified to monitor the performance of spent fuel in dry storage wells and self-shielded concrete casks. As the National Waste Terminal Storage (NWTS) programme advances to the next stage of underground site characterization for each of three different geological sites, additional pilot facilities are under consideration. These include a Test and Evaluation Facility (TEF) for site verification and equipment performance and testing, as well as a salt testing facility for verification of in situ simulation equipment. Although not associated with the NWTS programme, the construction of the Waste Isolation Pilot Plant (WIPP) in the bedded salts of New Mexico is well under way for deep testing and experimentation with the defence programme's transuranic nuclear waste.

  19. Online citizen panels as an advance in research and consultation – A Review of pilot results

    Directory of Open Access Journals (Sweden)

    Anne Sharp

    2010-07-01

    Full Text Available This paper details a new model for local government consultation and research. The model involves a local government partnering with a university to establish an online panel of citizens that is then used for consultations and research on a range of local government issues over time. The model was evaluated across an 18-month pilot involving three metropolitan councils in South Australia, each running its own panel. This paper details the rationale behind the panels, steps involved in their establishment, and what the most effective recruitment methods were to build panel membership. The model’s ability to recruit a wide audience of citizens as members, including those who would not normally participate in local government matters, is examined, as well as citizen expectations of the panel and satisfaction with being a member. Finally, key learnings from the pilot are identified. The pilot results demonstrate that such an online panel model can be used effectively in the local government context. The panels achieved citizen membership wider than that historically seen in local government consultation and research, and were sustainable in terms of continued participation and high levels of citizen satisfaction. Since the pilot, the project has grown to include seven councils and almost 2500 citizens. This is further evidence that this model offers a way forward for enhanced citizen participation in local government decision-making and policy development.

  20. A remotely piloted aircraft system in major incident management: concept and pilot, feasibility study.

    Abrahamsen, Håkon B

    2015-06-10

    Major incidents are complex, dynamic and bewildering task environments characterised by simultaneous, rapidly changing events, uncertainty and ill-structured problems. Efficient management, communication, decision-making and allocation of scarce medical resources at the chaotic scene of a major incident is challenging and often relies on sparse information and data. Communication and information sharing is primarily voice-to-voice through phone or radio on specified radio frequencies. Visual cues are abundant and difficult to communicate between teams and team members that are not co-located. The aim was to assess the concept and feasibility of using a remotely piloted aircraft (RPA) system to support remote sensing in simulated major incident exercises. We carried out an experimental, pilot feasibility study. A custom-made, remotely controlled, multirotor unmanned aerial vehicle with vertical take-off and landing was equipped with digital colour- and thermal imaging cameras, a laser beam, a mechanical gripper arm and an avalanche transceiver. We collected data in five simulated exercises: 1) mass casualty traffic accident, 2) mountain rescue, 3) avalanche with buried victims, 4) fisherman through thin ice and 5) search for casualties in the dark. The unmanned aerial vehicle was remotely controlled, with high precision, in close proximity to air space obstacles at very low levels without compromising work on the ground. Payload capacity and tolerance to wind and turbulence were limited. Aerial video, shot from different altitudes, and remote aerial avalanche beacon search were streamed wirelessly in real time to a monitor at a ground base. Electromagnetic interference disturbed signal reception in the ground monitor. A small remotely piloted aircraft can be used as an effective tool carrier, although limited by its payload capacity, wind speed and flight endurance. Remote sensing using already existing remotely piloted aircraft technology in pre

    2003-02-01

    The purpose of the Personal Environmental Risk Factor Study (PERFS) pilot project was to develop methodologies and a questionnaire for a future population-based case-control study to investigate the role of selected environmental exposures in breast cancer development. Identification of etiologically relevant exposures during a period of potential vulnerability proximate to disease onset offers the possibility of clinical disease prevention even when disease initiation may have already occurred many years earlier. Certain personal environmental agents or combinations of agents may influence disease promotion. Therefore, this pilot study focused on exposures that occurred during the ten-year period prior to diagnosis for cases and the last ten years for controls, rather than more historic exposures. For this pilot study, they used a community-based research approach. In the collaborative efforts, community members participated with academic researchers in all phases of the research, including research question identification, study design, development of research tools, development of the human subjects protocol, and report writing. Community member inclusion was based upon the concept that community participation could improve the relevance of scientific studies and ultimate success of the research by encouraging an ongoing dialogue between community members and academic representatives. Early activities of this project focused on the collection of input from the community regarding the possible role of environmental factors in the incidence of breast cancer in Marin County. The intent was to inform the scientists of community concerns, enhance the research team's understanding of the community being studied, and provide interested community members with a better understanding of the strengths and weaknesses of traditional research methods through active participation in the research process.

    Advanced Practice Nurses (APNs) need research skills to develop and advance their practice and, yet, many have limited access to research training and support following completion of their advanced degree. In this paper we report on the development, delivery, and evaluation of an innovative pilot program that combined research training and one-to-one mentorship for nine APNs in conducting research relevant to their practice. The program was organized within an academic institution and its affiliated hospitals in Toronto, Canada. Our experience with this program may assist those in other organizations to plan and deliver a similar program for APN research mentorship.

    To support reduction of racial disparities in mental health diagnosis and treatment, mental health researchers and black community-based organization (CBO) leaders need training on how to engage in collaborative research partnerships. In this study, we pilot tested a series of partnership skills training modules for researchers and CBO leaders in a collaborative learning format. Two different sets of three modules, designed for separate training of researchers and CBO leaders, covered considering, establishing and managing mental health research partnerships and included instructions for self-directed activities and discussions. Eight CBO leaders participated in 10 sessions, and six researchers participated in eight sessions. The effectiveness of the training content and format was evaluated through standardized observations, focus group discussions, participant evaluation forms and retrospective pre-/posttests to measure perceived gains in knowledge. Participants generally were satisfied with the training experience and gained new partnership knowledge and skills. Although the CBO leaders were more engaged in the cooperative learning process, this training format appealed to both audiences. Pilot testing demonstrated that: 1) our modules can equip researchers and CBO leaders with new partnership knowledge and skills and 2) the cooperative learning format is a well-received and suitable option for mental health research partnership training.

    We conducted a pilot study to investigate clinical efficacy of tyrosine kinase inhibitor erlotinib in the treatment of acute myeloid leukemia (AML). A total of 11 patients with de novo AML were treated, including 2 with relapsed and/or refractory disease and 9 older patients with previously untreated AML. Patients with high baseline leukocyte count were excluded. Erlotinib was given orally at 150 mg per day continuously in 28-day cycles. The treatment was tolerated well, and no toxicities were observed. An initial reduction in circulating blasts, followed by disease progression, was observed in 2 patients. Nine other patients did not demonstrate any response in blood or bone marrow. Baseline and post-cycle 1 flow-cytometry were performed on bone marrow blasts to investigate signs of differentiation. No immunophenotypic changes suggestive of differentiation were observed. This pilot study did not demonstrate response to standard doses of erlotinib in patients with AML.

    We report a pilot study with the Flower Workshop, a new modality of psychosocial rehabilitation group activity. Cognitive performance in schizophrenia and other mental conditions can be impaired depending on the tasks to be executed and their respective social context. The vulnerability of these individuals can be reduced by means of cognitive and socio-affective facilitation. We conducted a pilot study to introduce the Flower Workshop in a public Mental Health Service in the city of Ribeirão Preto (São Paulo-Brasil) with 12 participants during 18 months (2002-2003). With cognitive and socio-affective facilitation, participants were able to construct vases and make flower arrangements successfully.

    Full Text Available Aim: Hallux valgus is the deformity of the first metatarsophalangeal (MTP joint with abduction and valgus rotation of the great toe, combined with a medially prominent first metatarsal head. Hyaluronic acid injection has been used in the treatment of degenerative disorders of several joints successfully. In this research, we aimed to investigate the effectiveness of hyaluronic acid injection in patients with hallux valgus. Material and Method: Eleven female and two male patients with hallux valgus were included in this pilot study. Only patients with mild and moderate hallux valgus were included in the study. 1 cc hyaluronic acid was injected into the affected MTF joint three times, at one-week intervals. Visual analogue scale(VAS score, walking time without pain, walking distance, and daily analgesic needs of the patients were recorded. All clinical outcomes were assessed before, and then one and three months after the first injection. Results:The mean VAS score was 83.08±4.58. One month after the first injection, VAS scores of patients had decreased significantly (30±4.38, P: 0.001. Also, increased walking time and distance and decreased daily analgesic need were observed at the first month of postinjection follow-up (P: 0.001. After 3 months, the positive outcomes remained significant compared to preinjection evaluations. Discussion: According to our preliminary results, we suggest thathyaluronic acid injectionsmay be effective in reducing pain and increasing walking time and distance in patients with hallux valgus.Future studies are needed to clarify the beneficial effects of hyaluronic acid injection in patients with hallux valgus.

    Cervical auscultation (CA) may be used to complement feeding/swallowing evaluations when assessing for aspiration. There are no published pediatric studies that compare the properties of sounds between aspirating and nonaspirating swallows. To establish acoustic and perceptual profiles of aspirating and nonaspirating swallow sounds and determine if a difference exists between these 2 swallowing types. Aspiration sound clips were obtained from recordings using CA simultaneously undertaken with videofluoroscopic swallow study. Aspiration was determined using the Penetration-Aspiration Scale. The presence of perceptual swallow/breath parameters was rated by 2 speech pathologists who were blinded to the type of swallow. Acoustic data between groups were compared using Mann Whitney U-tests, while perceptual differences were determined by a test of 2 proportions. Combinations of perceptual parameters of 50 swallows (27 aspiration, 23 no aspiration) from 47 children (57% male) were statistically analyzed using area under a receiver operating characteristic (aROC), sensitivity, specificity, and positive and negative predictive values to determine predictors of aspirating swallows. The combination of post-swallow presence of wet breathing and wheeze and absence of GRS and normal breathing was the best predictor of aspiration (aROC = 0.82, 95% CI, 0.70-0.94). There were no significant differences between these 2 swallow types for peak frequency, duration, and peak amplitude. Our pilot study has shown that certain characteristics of swallow obtained using CA may be useful in the prediction of aspiration. However, further research comparing the acoustic swallowing sound profiles of normal children to children with dysphagia (who are aspirating) on a larger scale is required. © The Author(s) 2016.

    2017-10-01

    The rising prevalence of dementia is impacting on acute hospitals and placing increased expectations on health and social care professionals to improve the support and services they are delivering. It has been recommended that good practice in dementia care relies on adopting a palliative approach to care and meeting people's physical, psychological, social and spiritual needs. Increased dementia training for staff that includes initiatives that promote dignity; enhancing communication skills and recognizing that a person with dementia may be approaching the end of their lives are needed. Our study aim was to explore whether Namaste Care is an acceptable and effective service for people with advanced dementia being cared for on an acute hospital ward. This was an exploratory qualitative interview, pilot study. Individual, semi-structured, face-to-face interviews were conducted with hospital healthcare staff working in an area of the hospital where Namaste Care had been implemented. Data were analysed using the framework approach. Eight interviews were completed with members of the multidisciplinary ward team. Two themes were identified: (I) difficulties establishing relationships with people with dementia in hospital (subthemes: lack of time and resources, lack of confidence leading to fear and anxiety); (II) the benefits of a Namaste Care service in an acute hospital setting (subthemes: a reduction in agitated behavior; connecting and communicating with patients with dementia using the senses; a way of showing people with dementia they are cared for and valued). This small-scale study indicates that Namaste Case has the potential to improve the quality of life of people with advanced dementia being cared for in an acute hospital setting. However, further research is required to explore more specifically its benefits in terms of improved symptom management and wellbeing of people with dementia on acute hospitals wards.

    Before establishing a prospective cohort, an initial pilot study is recommended. However, there are no precise guidelines on this subject. This paper reports the findings of a French regional pilot study carried out in three nephrology departments, before realizing a major prospective Non Dialysis Chronic Renal Insufficiency study (ND-CRIS). We carried out an internal pilot study. The objectives of this pilot study were to validate the feasibility (regulatory approval, providing patients with information, availability of variables, refusal rate of eligible patients) and quality criteria (missing data, rate of patients lost to follow-up, characteristics of the patients included and non-included eligible patients, quality control of the data gathered) and estimate the human resources necessary (number of clinical research associates required). The authorizations obtained (CCTIRS - CNIL) and the contracts signed with hospitals have fulfilled the regulatory requirements. After validating the information on the study provided to patients, 1849 of them were included in three centres (university hospital, intercommunal hospital, town hospital) between April 2012 and September 2015. The low refusal rate (51 patients) and the characteristics of non-included patients have confirmed the benefit for patients of participating in the study and provide evidence of the feasibility and representativeness of the population studied. The lack of missing data on the variables studied, the quality of the data analyzed and the low number of patients lost to follow-up are evidence of the quality of the study. By taking into account the time spent by CRAs to enter data and to travel, as well as the annual patient numbers in each hospital, we estimate that five CRAs will be required in total. With no specific guidelines on how to realize a pilot study before implementing a major prospective cohort, we considered it pertinent to report our experience of P-ND-CRIS. This experience confirms

    This paper describes pilot studies which have been implemented to study the aging behavior of safety related component parts of nuclear power plants. In 1989 the IAEA initiated work on pilot studies related to the aging of such components. Four components were identified for study. They are the primary nozzle of a reactor vessel; a motor operated isolating valve; the concrete containment building; and instrumentation and control cables within the containment facility. The study was begun with phase 1 efforts directed toward understanding the aging process, and methods for monitoring and minimizing the effects of aging. Phase 2 efforts are directed toward aging studies, documentation of the ideas put forward, and research to answer questions identified in phase 1. This paper describes progress made on two of these components, namely the motor operated isolation valves, and in-containment I ampersand C cables

    The purpose of this pilot study was to establish the feasibility of completing a future controlled trial of a multi-component cognitive behavioral therapy for insomnia program for military veterans with sleep disturbance. This was a single-arm feasibility and pilot study. Participants were United States post-9/11 veterans with service-connected injuries, university students, and had self-reported sleep disturbances. Restoring Effective Sleep Tranquility was a multi-component cognitive behavioral therapy for insomnia intervention consisting of seven sessions of group therapy and eight 1:1 sessions delivered by occupational therapists. Feasibility and pilot indicators were process, resources, management, and scientific, including pre-post-assessments of sleep difficulties, dysfunctional sleep beliefs, participation, and pain interference. Indicators were supportive of feasibility, including reduced sleep difficulties (for example Medical Outcomes Study Sleep Measure [ t  = 3.29, p  = .02]), reduced nightmares: t  = 2.79, p  = .03; fewer dysfunctional sleep beliefs: t  = 3.63, p  = .01, and greater ability to participate in social roles: t  = -2.86, p  = .03, along with trends towards improved satisfaction with participation and reduced pain interference. The Restoring Effective Sleep Tranquility program may reduce sleep difficulties and improve participation in US veterans with service-connected injuries, and evidence indicates a controlled trial would be feasible to deliver.

    A ballasted-flocculation pilot-scale study was undertaken to treat a wide-range river water turbidity (17 to 2,608 NTU). The pilot-scale unit was operated at flowrates of 30 to 63 m 3 /h, which corresponded to loading rates of 40 to 84 m/h. Coagulants, polymers, and microsand were added to enhance the floc agglomeration. The weighted flocs settled rapidly resulting in excellent turbidity removals of 94.7 to 99.9%. At the peak turbidity, the unit had a 99.9% removal performance (2.7 from 2,608 NTU) at a loading rate of 40 m/h. In this case, polyaluminum silicosulfate and anionic polymer dosages were 82 and 1 mg/L, respectively. The microsand recycle rate was kept constant at 4.5 m 3 /h, and 1mg microsand was added for each liter of water treated. (author)

    Urine collection containers used in the doping control collection procedure do not provide a protective environment for urine, against degradation by microorganisms and proteolytic enzymes. An in-house chemical stabilization mixture was developed to tackle urine degradation problems encountered in human sport samples, in cases of microbial contamination or proteolytic activity. The mixture consists of antimicrobial substances and protease inhibitors for the simultaneous inactivation of a wide range of proteolytic enzymes. It has already been tested in lab-scale, as part of World Anti-Doping Agency's (WADA) funded research project, in terms of efficiency against microbial and proteolytic activity. The present work, funded also by WADA, is a follow-up study on the improvement of chemical stabilization mixture composition, application mode and limitation of interferences, using pilot urine collection containers, spray-coated in their internal surface with the chemical stabilization mixture. Urine in plastic stabilized collection containers have been gone through various incubation cycles to test for stabilization efficiency and analytical matrix interferences by three WADA accredited Laboratories (Athens, Ghent, and Rome). The spray-coated chemical stabilization mixture was tested against microorganism elimination and steroid glucuronide degradation, as well as enzymatic breakdown of proteins, such as intact hCG, recombinant erythropoietin and small peptides (GHRPs, ipamorelin), induced by proteolytic enzymes. Potential analytical interferences, observed in the presence of spray-coated chemical stabilization mixture, were recorded using routine screening procedures. The results of the current study support the application of the spray-coated plastic urine container, in the doping control collection procedure. Copyright © 2016 John Wiley & Sons, Ltd.

    To ensure appropriate allocation of research funds, we need methods for identifying high-priority research needs. We developed and pilot tested a process to identify needs for primary clinical research using a systematic review in gestational diabetes mellitus. We conducted eight steps: abstract research gaps from a systematic review using the Population, Intervention, Comparison, Outcomes, and Settings (PICOS) framework; solicit feedback from the review authors; translate gaps into researchable questions using the PICOS framework; solicit feedback from multidisciplinary stakeholders at our institution; establish consensus among multidisciplinary external stakeholders on the importance of the research questions using the Delphi method; prioritize outcomes; develop conceptual models to highlight research needs; and evaluate the process. We identified 19 research questions. During the Delphi method, external stakeholders established consensus for 16 of these 19 questions (15 with "high" and 1 with "medium" clinical benefit/importance). We pilot tested an eight-step process to identify clinically important research needs. Before wider application of this process, it should be tested using systematic reviews of other diseases. Further evaluation should include assessment of the usefulness of the research needs generated using this process for primary researchers and funders. Copyright © 2013 Elsevier Inc.

    2004-12-01

    A pilot study of Seaside, Oregon is underway, to develop methodologies for probabilistic tsunami hazard assessments that can be incorporated into Flood Insurance Rate Maps (FIRMs) developed by FEMA's National Flood Insurance Program (NFIP). Current NFIP guidelines for tsunami hazard assessment rely on the science, technology and methodologies developed in the 1970s; although generally regarded as groundbreaking and state-of-the-art for its time, this approach is now superseded by modern methods that reflect substantial advances in tsunami research achieved in the last two decades. In particular, post-1990 technical advances include: improvements in tsunami source specification; improved tsunami inundation models; better computational grids by virtue of improved bathymetric and topographic databases; a larger database of long-term paleoseismic and paleotsunami records and short-term, historical earthquake and tsunami records that can be exploited to develop improved probabilistic methodologies; better understanding of earthquake recurrence and probability models. The NOAA-led U.S. National Tsunami Hazard Mitigation Program (NTHMP), in partnership with FEMA, USGS, NSF and Emergency Management and Geotechnical agencies of the five Pacific States, incorporates these advances into site-specific tsunami hazard assessments for coastal communities in Alaska, California, Hawaii, Oregon and Washington. NTHMP hazard assessment efforts currently focus on developing deterministic, "credible worst-case" scenarios that provide valuable guidance for hazard mitigation and emergency management. The NFIP focus, on the other hand, is on actuarial needs that require probabilistic hazard assessments such as those that characterize 100- and 500-year flooding events. There are clearly overlaps in NFIP and NTHMP objectives. NTHMP worst-case scenario assessments that include an estimated probability of occurrence could benefit the NFIP; NFIP probabilistic assessments of 100- and 500-yr

    The Energy Efficiency (EE) plays an important role over the building life cycle and the implementation of EE in refurbishment projects has a significant potential towards the reduction of greenhouse gas emissions. However, the involvement of the design team at the early stage of the refurbishment projects will determine the success of EE implementations. Thus, a pilot study was conducted at the initial stage of the data collection process of this research to validate and verify the questionnaires.

    This study evaluated a novel high-resolution breast-specific gamma camera (HRBGC) for the detection of suggestive breast lesions. Methods: Fifty patients (with 58 breast lesions) for whom a scintimammogram was clinically indicated were prospectively evaluated with a general-purpose gamma camera and a novel HRBGC prototype. The results of conventional and high-resolution nuclear studies were prospectively classified as negative (normal or benign) or positive (suggestive or malignant) by 2 radiologists who were unaware of the mammographic and histologic results. All of the included lesions were confirmed by pathology. Results: There were 30 benign and 28 malignant lesions. The sensitivity for detection of breast cancer was 64.3% (18/28) with the conventional camera and 78.6% (22/28) with the HRBGC. The specificity with both systems was 93.3% (28/30). For the 18 nonpalpable lesions, sensitivity was 55.5% (10/18) and 72.2% (13/18) with the general-purpose camera and the HRBGC, respectively. For lesions 1 cm, 7 of 15 were detected with the general-purpose camera and 10 of 15 with the HRBGC. Four lesions (median size, 8.5 mm) were detected only with the HRBGC and were missed by the conventional camera. Conclusion: Evaluation of indeterminate breast lesions with an HRBGC results in improved sensitivity for the detection of cancer, with greater improvement shown for nonpalpable and 1-cm lesions.

    It is well established that sedentariness is the largest, preventable contributor to premature death, eclipsing smoking in recent years. One approach to reduce sedentariness is by using a treadmill desk to perform office work while walking at a low speed.We found an increased interest level when the treadmill desks were first introduced to LANL, but after a few months interest appeared to drop. It is possible that treadmill desk use was occurring, but subjects did not record their use. The treadmill desks will not be readily available for purchase by employees due to the study outcome. Additionally, conclusive changes in body measurements could not be performed due to lack of follow up by 58% of the participants.

    This paper presents an overview of the flight management work being conducted using NASA Langley's oculometer system. Tests have been conducted in a Boeing 737 simulator to investigate pilot scan behavior during approach and landing for simulated IFR, VFR, motion versus no motion, standard versus advanced displays, and as a function of various runway patterns and symbology. Results of each of these studies are discussed. For example, results indicate that for the IFR approaches a difference in pilot scan strategy was noted for the manual versus coupled (autopilot) conditions. Also, during the final part of the approach when the pilot looks out-of-the-window he fixates on his aim or impact point on the runway and holds this point until flare initiation.

  10. Medical exposure to children - a pilot study

    Ingilizova, K.; Borisova, R.

    2008-01-01

    Patient dose assessment during medical exposure in paediatric diagnostic radiology is of highest importance in view of the greater radiation hazard to children compared to adults. It is conditioned by their higher sensitivity to ionizing radiation and their greater life expectancy. The risk of stochastic effects is several times greater for children than for adults. The attributive risk to children exposed to ionizing radiation during the first 10 years is 3 to 5 times greater than the risk to adults exposed between 30 and 40 years of age, and 6 to 7 times greater compared to the risk to adults exposed after their 50 year. The children dose distribution studies are carried out in order to elaborate national diagnostic reference levels. The dose assessment is complicated by the great variation in body size and anatomical features of children belonging to different age groups. There is a series of difficulties in the definition of image quality criteria and guidelines for good practice due to the dynamically changing body proportions and the anatomical features as a result of the active growth process from infancy through early childhood to adolescence.

    Frailty can be defined as an inflammatory state with a loss of physiologic reserve in multiple systems that manifests as a decreased ability to respond to stressors that ultimately leads to an increased risk of adverse outcomes. The aim of this study was to determine the ease of frailty testing in a pre-kidney transplant clinic and the resources required to do so. A secondary goal was to better understand the utility of frailty testing when evaluating potential kidney transplant recipients. Frailty testing was conducted at a pre-kidney transplant clinic in three phases using Fried's frailty phenotype (shrinking, exhaustion, low physical activity, slowness, and grip strength). A total of 132 frailty tests were completed on 128 patients. Frail patients had significantly higher rates of shrinking (26% vs. 8.5%, P testing was most complete when an examiner dedicated to frailty testing performed the testing. Frailty testing is feasible to complete in a pre-transplant clinic with an appropriate investment in personnel and resources.

    The purpose of the present study was to assess the social skills of euthymic patients with bipolar disorder. A group of 25 outpatients with bipolar disorder type I were evaluated in comparison with a group of 31 healthy volunteers who were matched in terms of level of education, age, sex and intelligence. Both groups were assessed using a self-report questionnaire, the Brazilian Inventario de Habilidades Sociais (IHS, Social Skills Inventory). Two Wechsler Adult Intelligence Scale subtests (Picture Arrangement and Comprehension) were also used in order to assess subject ability to analyse social situations and to make judgements, respectively. Patients with bipolar disorder had lower IHS scores for the domains that assessed conversational skills/social self-confidence and social openness to new people/situations. Patients with anxiety disorders had high scores for the domain that assessed self-confidence in the expression of positive emotions. No differences were found between patients and controls in performance on the Wechsler Adult Intelligence Scale Picture Arrangement and Comprehension subtests. Euthymic patients with bipolar disorder present inhibited and overattentive behaviour in relation to other people and their environment. This behaviour might have a negative impact on their level of social functioning and quality of life.

    We studied occupational stress and its psychosocial effects in a sample of Italian radiologists and radiotherapists: Radiologists and radiotherapists attending two medical conferences were invited to complete a questionnaire comprising four sections investigating the risk of occupational stress (organisational discomfort, Karasek's Job Content Questionnaire, Siegrist's Effort-Reward Imbalance, Warr's Job Satisfaction) and four sections investigating the health effects of such stress (Goldberg's Anxiety and Depression Scales, General Health Questionnaire, Lifestyles Questionnaire). Radiologists and radiotherapists generally expressed high levels of control, reward and satisfaction. However, 38.5% complained of severe organisational discomfort, 24% reported job strain, 28% reported effort/reward imbalance and 25% were dissatisfied. Female radiologists and radiotherapists showed higher levels of organisational discomfort than their male colleagues. Younger and less experienced radiologists and radiotherapists had higher strain scores than their older and more experienced colleagues. A significant correlation was observed between stress predictors and the effects of stress on health, including depression and anxiety, psychological distress and unhealthy lifestyles. Radiologists and radiotherapists are exposed to major occupational stress factors, and a significant percentage of them suffer from workplace stress. A special effort is required to prevent this condition.

    Complete text of publication follows. In the cooperation between KITE Ltd., Nadudvar, Hungary and the Hertelendi Laboratory of Environmental Studies, the aim was to determine the ideal locations of fertilising, the ideal distance of rows for the ideal production yield. To track the nitrogen utilisation of maize (Zea mays) 15 N enriched NH 4 NO 3 fertiliser was introduced among the usual fertilisers in the maize field of KITE Ltd. Nadudvar, Hungary on 30 th March 2012, before sowing. Four maize samples were taken from different areas of different fertiliser treatment (non-fertilised and non-labelled, fertilised and non-labelled, fertilised and labelled between the rows and fertilised and labelled within the rows) and from different development stages of the plant on 22 nd May, 8 th June, 6 th July and 7 th September being sampling periods 1-4, respectively. The plant samples were subsampled based on organs: root, stem and leaf. Samples were dried to constant mass and pulverised. The 15 N measurements were made by a Thermo Finnigan Delta PLUS XP isotope ratio mass spectrometer coupled with an elemental analyser. In case of non-fertilised and non-labelled plants, all the three organs were getting 15 N depleted with time, most intensively the stem and the less intensively the root (Figure 1). For the leaves and stems of the fertilised and non-labelled plants, the tendency in time is very similar to the ones of the non-fertilised and non-labelled plants, however, the roots of the fertilised and non-labelled plants got significantly enriched in the sample of September. In case of the fertilised and labelled between-the-rows samples, labelling is slightly seen as the delta values are positive. These values are significantly lower than the ones for the fertilised and labelled-within-the-rows plants. It is seen that fertiliser got to the vegetation in the largest extent in this layout. Labelling showed its maximum intensity in the second sampling (8 th June) showing that

    Peripheral sensory neuropathy is a neurological deficit resulting in decreased detection of sensation through the peripheral nervous system. Peripheral sensory neuropathy is commonly diagnosed with the use of a monofilament and either a tuning fork or neurothesiometer. Statins are a widely used medication and there has been some debate of association with their use and peripheral sensory neuropathy. This pilot study aimed to test the sensory perception of participants with long-term statin use and compare these results to their peers who were not taking statins. Thirty participants were recruited and equally divided into a statin and non-statin group. Healthy participants were screened by their medical and medication history, Australian Type 2 Diabetes Risk assessment, and random blood glucose level. An assessor who was blinded to the participant group conducted sensory assessments using a 10 g monofilament and neurothesiometer. There was no difference in monofilament testing results between the groups. The statin group was less sensate at the styloid process (p = 0.031) and medial malleolus (p = 0.003) than the control group. Results at the hallux were not statistically significant (p = 0.183). This result is suggestive of a potential association between long-term statin use and a decrease in peripheral sensory perception. This may be because of peripheral sensory neuropathy. Limitations such as consideration of participant height, participant numbers, and inability to analyze results against statin groups are reported. As statins are a life-saving medication, careful consideration should be applied to these results and further research be conducted to determine if these results are applicable to larger populations.

    The patient experience has moved to the forefront of health care-delivery research. The University of Texas MD Anderson Cancer Center Department of Diagnostic Radiology began collaborating in 2011 with the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management, and in 2013 with the University of Nevada, Las Vegas, William F. Harrah College of Hotel Administration, to explore the application of service science to improving the patient experience. A collaborative pilot study was undertaken by these 3 institutions to identify and rank the specific needs and expectations of patients undergoing imaging procedures in the MD Anderson Department of Diagnostic Radiology. We first conducted interviews with patients, providers, and staff to identify factors perceived to affect the patient experience. Next, to confirm these factors and determine their relative importance, we surveyed more than 6,000 patients by e-mail. All factors considered important in the interviews were confirmed as important in the surveys. The surveys showed that the most important factors were acknowledgment of the patient's concerns, being treated with respect, and being treated like a person, not a "number"; these factors were more important than privacy, short waiting times, being able to meet with a radiologist, and being approached by a staff member versus having one's name called out in the waiting room. Our work shows that it is possible to identify and rank factors affecting patient satisfaction using techniques employed by the hospitality industry. Such factors can be used to measure and improve the patient experience. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    The purpose of this pilot study was to describe the experiences, support needs, resources, and barriers to support for fathers whose partners had post-partum depression (PPD) in preparation for a larger study. Qualitative methods and community-based research approaches were used in this exploratory/descriptive multi-site study, conducted in New Brunswick and Alberta. Telephone interviews were conducted with a total of 11 fathers in New Brunswick (n= 7) and Alberta (n= 4). Fathers experienced a number of depressive symptoms including: anxiety, lack of time and energy, irritability, feeling sad or down, changes in appetite, and thoughts of harm to self or baby. The most common barriers for fathers were lack of information regarding PPD resources and difficulty seeking support. This pilot study establishes the feasibility of the larger-scale exploration of fathers' experiences in supporting their spouses affected by PPD. © 2010 Blackwell Publishing.

    A joint research had been carried out with a subsidy from the Agency of Natural Resources and Energy since fiscal 1988 to fiscal 1995 on the direct iron ore smelting reduction process (DIOS process). The process utilizes coal directly as a process to use the strong points and supplement the weak points of the blast furnace process. During the period, a pilot plant had been operated since 1993. Upon having completed the feasibility study, this paper reports the result thereof. The main facilities consist of a smelting and reducing furnace of iron bath type, a spare reducing furnace of fluidized bed type, and a preheating furnace. The former two furnaces constitute a unit structure with the two furnaces connected vertically. The pilot plant achieved a three-day continuous operation producing 500 tons of iron every day. The production rate reached 21 tons an hour at an upward oxygen blowing velocity of about 13,000 Nm {sup 3} per hour. The coal unit requirement showed a result of <1000 kg/t for high VM coal and <900 kg/t for low VM coal. These results verified a possibility that this process can supplement or replace the blast furnace process even for a production scale of 9000 tons a day. 7 refs., 15 figs., 3 tabs.

    The DOE's Big Sky Regional Carbon Sequestration Partnership has completed drilling the first continental flood basalt sequestration pilot borehole to a total depth (TD) of 4,110 feet on the Boise White Paper Mill property at Wallula, Washington. Site suitability was assessed prior to drilling by the 2007-2008 acquisition, processing and analysis of a four-mile, five-line three component seismic swath, which was processed as a single data-dense line. Analysis of the seismic survey data indicated a composite basalt formation thickness of {approx}8,000 feet and absence of major geologic structures (i.e., faults) along the line imaged by the seismic swath. Drilling of Wallula pilot borehole was initiated on January 13, 2009 and reached TD on April 6, 2009. Based on characterization results obtained during drilling, three basalt breccia zones were identified between the depth interval of 2,716 and 2,910 feet, as being suitable injection reservoir for a subsequent CO2 injection pilot study. The targeted injection reservoir lies stratigraphically below the massive Umtanum Member of the Grande Ronde Basalt, whose flow-interior section possesses regionally recognized low-permeability characteristics. The identified composite injection zone reservoir provides a unique and attractive opportunity to scientifically study the reservoir behavior of three inter-connected reservoir intervals below primary and secondary caprock confining zones. Drill cuttings, wireline geophysical logs, and 31one-inch diameter rotary sidewall cores provided geologic data for characterization of rock properties. XRF analyses of selected rock samples provided geochemical characterizations of the rocks and stratigraphic control for the basalt flows encountered by the Wallula pilot borehole. Based on the geochemical results, the pilot borehole was terminated in the Wapshilla Ridge 1 flow of the Grande Ronde Basalt Formation.

    The Germanwings Flight 9525 crash has brought the sensitive subject of airline pilot mental health to the forefront in aviation. Globally, 350 million people suffer from depression-a common mental disorder. This study provides further information on this important topic regarding mental health especially among female airline pilots. This is the first study to describe airline pilot mental health-with a focus on depression and suicidal thoughts-outside of the information derived from aircraft accident investigations, regulated health examinations, or identifiable self-reports, which are records protected by civil aviation authorities and airline companies. This is a descriptive cross-sectional study via an anonymous web-based survey administered between April and December 2015. Pilots were recruited from unions, airline companies, and airports via convenience sampling. Data analysis included calculating absolute number and prevalence of health characteristics and depression scores. One thousand eight hundred thirty seven (52.7%) of the 3485 surveyed pilots completed the survey, with 1866 (53.5%) completing at least half of the survey. 233 (12.6%) of 1848 airline pilots responding to the Patient Health Questionnaire 9 (PHQ-9), and 193 (13.5%) of 1430 pilots who reported working as an airline pilot in the last seven days at time of survey, met depression threshold-PHQ-9 total score ≥ 10. Seventy-five participants (4.1%) reported having suicidal thoughts within the past two weeks. We found a significant trend in proportions of depression at higher levels of use of sleep-aid medication (trend test z = 6.74, p sexual harassment (z = 3.18, p = 0.001) or verbal harassment (z = 6.13, p < 0.001). Hundreds of pilots currently flying are managing depressive symptoms perhaps without the possibility of treatment due to the fear of negative career impacts. This study found 233 (12.6%) airline pilots meeting depression threshold and 75 (4.1%) pilots

    Full Text Available Angelique Egberts, Francesco US Mattace-Raso Section of Geriatric Medicine, Department of Internal Medicine, Erasmus University Medical Center, Rotterdam, the Netherlands Aim: Delirium is a common and severe complication among older hospitalized patients. The pathophysiology is poorly understood, but it has been suggested that inflammation and oxidative stress may play a role. The aim of this pilot study was to investigate levels of the neutrophil–lymphocyte ratio (NLR – a marker of systemic inflammation and oxidative stress – in patients with and without delirium. Methods: This pilot study was performed within a retrospective chart review study that included acutely ill patients, 65 years and older, who were admitted to the ward of geriatrics of the Erasmus University Medical Center. All patients in whom the differential white blood cell (WBC counts as well as the C-reactive protein (CRP level were determined within 24 h after admission were included in the present study. Differences in NLR between patients with and without delirium were investigated using univariate analysis of variance, with adjustments for age, sex, comorbidities, CRP level, and total WBC count. Results: Eighty-six patients were included. Thirteen patients were diagnosed with delirium. In adjusted models, higher mean NLR values were found in patients with, than in those without, delirium (9.10 vs 5.18, P=0.003. Conclusion: In this pilot study, we found increased NLR levels in patients with delirium. This finding might suggest that an inadequate response of the immune system and oxidative stress may play a role in the pathogenesis of delirium. Further studies are needed to confirm the association between NLR and delirium. Keywords: delirium, pathology, biomarkers, leukocytes, immune system, brain

    The paper describes the design and preliminary results of an extended pilot study of commercially available monitoring systems for the detection of nuclear and other radioactive materials at borders. The study consists of a laboratory test phase and field tests at the Austrian/Hungarian border and the Vienna airport, each for a duration of one year. The results will be used to derive realistic performance requirements for border control systems in view of optimized technical and economic conditions as well as to propose an 'investigation level'. The ITRAP study consists of three phases. In the first phase equipment currently available on the market is subjected to laboratory testing at the Austrian Research Centres Seibersdorf. The instrument categories include hand-held, portable, and fixed-installed equipment. The test criteria defined as minimum requirements have been established together with the manufacturers. The laboratory tests started in May 1998 and will last until end of this year. During the second phase, the field study, equipment passing the laboratory tests will be installed at a major Austrian-Hungarian border crossing (Nickelsdorf) for monitoring of cars, trucks and trains, as well as at the Vienna airport for pedestrians, luggage and cargo. In this phase the results gained from the lab tests about the 'fitness for use' will be verified in practice, in close co-operation with the law enforcement officers at the borders. Also training issues and questions of maintenance and support shall be evaluated. In the third phase, realistic specifications and performance requirements shall be derived with the help of international experts and selected specialists from the users and manufacturers. The results of the field study will focus not only on the technical aspects of monitoring equipment (e.g. detection threshold and rate of false alarms) but also on the operational (e.g. ease of use, reliability, training requirements, field support) and economic

    Most of the objectives, set for the Pilot Study, were met. It can be concluded that the methodology was adequate for its purpose. National requirements on selected safety issues have been systematically compared and the major gaps and differences have been identified. Convenient overviews have been provided of differences and similarities between the countries. Furthermore, the conclusions are based on a safety justification and are detailed enough to provide input to a further more detailed analysis on the national level. It was not possible, however, to provide fully verified conclusions about the implementation of the reference levels in the different countries. This has to do with the following constraints on the study: In line with the Terms of Reference, the comparison of formal requirements did not address the more detailed use of criteria and methods to verify compliance. The same requirement could be enforced differently in different regulatory systems, and hence lead to different implementation. The Pilot Study also assessed the implementation, but it was not possible to do this in sufficient detail to identify such differences. The implementation was assessed on the basis of current knowledge of the respective regulatory body, but it was not possible to provide the panels with evidence of the implementation. For these reasons, conclusions about implemented safety provisions in the different countries should be drawn with precaution. The introduction of the panel assessments greatly improved the quality and consistency of the comparison assessments. Uncertainties in the assessments are mainly connected with lack of time to make a detailed analysis in some cases. The reliability of the assessments seems to be sufficient for the objectives of the Pilot Study. The introduction of the IAEA safety standards in the study proved to be helpful and provided confidence in the scope and strictness of the reference levels. This Pilot Study has contributed to

    Moral case deliberation (MCD) as a form of clinical ethics support is usually implemented in health care institutions and educational programs. While there is no previous research on the use of clinical ethics support on the level of health care regulation, employees of regulatory bodies are regularly confronted with moral challenges. This pilot study describes and evaluates the use of MCD at the Dutch Health Care Inspectorate (IGZ). The objective of this pilot study is to investigate: 1) the current way of dealing with moral issues at the IGZ; 2) experience with and evaluation of MCD as clinical ethics support, and 3) future preferences and (perceived) needs regarding clinical ethics support for dealing with moral questions at the IGZ. We performed an explorative pilot study. The research questions were assessed by means of: 1) interviews with MCD participants during four focus groups; and 2) interviews with six key stakeholders at the IGZ. De qualitative data is illustrated by data from questionnaires on MCD outcomes, perspective taking and MCD evaluation. Professionals do not always recognize moral issues. Employees report a need for regular and structured moral support in health care regulation. The MCD meetings are evaluated positively. The most important outcomes of MCD are feeling secure and learning from others. Additional support is needed to successfully implement MCD at the Inspectorate. We conclude that the respondents perceive moral case deliberation as a useful form of clinical ethics support for dealing with moral questions and issues in health care regulation.

    Art and art therapy open up interesting possibilities for dementia patients. However, it has not been evaluated scientifically so far, whether the art of sculpting has any benefits. In this non-randomized pilot study with twelve participants, we investigated the feasibility and acceptance of sculptural activity in patients with dementia and the effects on their well-being. A questionnaire was custom-designed to investigate five key aspects of well-being: mental state and concentration, corporeal memory, self-reliance, self-esteem and physicality. Remarkable improvements were seen in several subscales in the sculptural activity group, but not the control group: Mental state and concentration (nine of thirteen key aspects), self-reliance (four of five), self-esteem (one of one) and physicality (two of two). The results of this pilot study indicate the multidimensional effects of sculptural activity on patients living with dementia. The field would benefit greatly from further research.

    Full Text Available Complex billing practices cost the US healthcare system billions of dollars annually. Coding for outpatient office visits [known as Evaluation & Management (E&M services] is commonly particularly fraught with errors. The best way to insure proper billing and coding by practicing physicians is to teach this as part of the medical school curriculum. Here, in a pilot study, we show that medical students can learn well the basic principles from lectures. This approach is easy to implement into a medical school curriculum.

Oblique-wing airplanes show large cross-coupling in control and dynamic behavior which is not present on conventional symmetric airplanes and must be compensated for to obtain acceptable handling qualities. The large vertical motion simulator at NASA Ames-Moffett was used in the piloted evaluation of a proposed flight control system designed to provide decoupled handling qualities. Five discrete flight conditions were evaluated ranging from low altitude subsonic Mach numbers to moderate altitude supersonic Mach numbers. The flight control system was effective in generally decoupling the airplane. However, all participating pilots objected to the high levels of lateral acceleration encountered in pitch maneuvers. In addition, the pilots were more critical of left turns (in the direction of the trailing wingtip when skewed) than they were of right turns due to the tendency to be rolled into the left turns and out of the right turns. Asymmetric side force as a function of angle of attack was the primary cause of lateral acceleration in pitch. Along with the lateral acceleration in pitch, variation of rolling and yawing moments as functions of angle of attack caused the tendency to roll into left turns and out of right turns.

    Full Text Available In the modern world, the environment of any educational institution represents a spectrum of ethnic groups and subcultures: a multicultural educational environment. Pupils who are aware of their national identity often demonstrate intolerance toward students of other nationalities, which threatens pupils’ psychological safety. In this article, we present the results of pilot research examining the level of a pupil’s psychological safety in the multicultural educational environment and identifying the criteria that influence a pupil’s psychological safety. The research sample comprised 127 pupils aged 13–14 years from different schools living in various places that differed by the type of settlement, industrial development and level of science and culture. We isolated the following criteria for a pupil’s psychological safety in the multicultural educational environment: satisfaction with the educational environment, protection from psychological abuse and self-confidence. According to pupils, the essential characteristics of safety in the educational environment, regardless of school category and type, are being able to ask for help, protection of personal dignity, interactions with other students, and self-respect. Empirical data reveal the current status of the psychological safety of the entire sample group (n = 127 and compare indices of psychological safety in the educational institutions under study. Analysis of the results of our research indicates that protecting a pupil’s personality in the multicultural educational environment has the greatest influence on his/her psychological safety. In addition, a comfortable psychological atmosphere, mutual aid and support of pupils and low levels of classmates’ and coevals’ aggression positively influence the protection experience.

    The Geothermal Pilot Study under the auspices of the Committee on the Challenges of Modern Society (CCMS) was established in 1973 to apply an action-oriented approach to international geothermal research and development, taking advantage of the established channels of governmental communication provided by the North Atlantic Treaty Organization (NATO). The Pilot Study was composed of five substudies. They included: computer-based information systems; direct application of geothermal energy; reservoir assessment; small geothermal power plants; and hot dry rock concepts. The most significant overall result of the CCMS Geothermal Pilot Study, which is now complete, is the establishment of an identifiable community of geothermal experts in a dozen or more countries active in development programs. Specific accomplishments include the creation of an international computer file of technical information on geothermal wells and fields, the development of studies and reports on direct applications, geothermal fluid injection and small power plants, and the operation of the visiting scientist program. In the United States, the computer file has aready proven useful in the development of reservoir models and of chemical geothermometers. The state-of-the-art report on direct uses of geothermal energy is proving to be a valuable resource document for laypersons and experts in an area of increasing interest to many countries. Geothermal fluid injection studies in El Salvador, New Zealand, and the United States have been assisted by the Reservoir Assessment Substudy and have led to long-range reservoir engineering studies in Mexico. At least seven small geothermal power plants are in use or have been planned for construction around the world since the Small Power Plant Substudy was instituted--at least partial credit for this increased application can be assigned to the CCMS Geothermal Pilot Study.

    Half of all adults in the United States do not meet the level of recommended aerobic physical activity. Physical activity interventions are now being conducted in the workplace. Accessible technology, in the form of widespread usage of cell phones and text messaging, is available for promoting physical activity. The purposes of this study, which was conducted in the workplace, were to determine (1) the feasibility of implementing a bilingual 12-week Text4Walking intervention and (2) the effect of the Text4Walking intervention on change in physical activity and health status in a food service employee population. Before conducting the study reported here, the Text4Walking research team developed a database of motivational physical activity text messages in English. Because Hispanic or Latino adults compose one-quarter of all adults employed in the food service industry, the Text4Walking team translated the physical activity text messages into Spanish. This pilot study was guided by the Physical Activity Health Promotion Framework and used a 1-group 12-week pre- and posttest design with food service employees who self-reported as being sedentary. The aim of the study was to increase the number of daily steps over the baseline by 3000 steps. Three physical activity text messages were delivered weekly. In addition, participants received 3 motivational calls during the study. SPSS version 19.0 and R 3.0 were used to perform the data analysis. There were 33 employees who participated in the study (57.6% female), with a mean age of 43.7 years (SD 8.4). The study included 11 Hispanic or Latino participants, 8 of whom requested that the study be delivered in Spanish. There was a 100% retention rate in the study. At baseline, the participants walked 102 (SD 138) minutes/day (per self-report). This rate increased significantly (P=.008) to 182 (SD 219) minutes/day over the course of the study. The participants had a baseline mean of 10,416 (SD 5097) steps, which also increased

    To summarize and then assess with a pilot study the use of published best practice recommendations for priority setting during management of multiple healthcare research projects, in a resource-constrained environment. Medical, economic, business, and operations literature was reviewed to summarize and develop a survey to assess best practices for managing multiple projects. Fifteen senior healthcare research project managers, directors, and faculty at an urban academic institution were surveyed to determine most commonly used priority rules, ranking of rules, characteristics of their projects, and availability of resources. Survey results were compared to literature recommendations to determine use of best practices. Seven priority-setting rules were identified for managing multiple projects. Recommendations on assigning priorities by project characteristics are presented. In the pilot study, a large majority of survey respondents follow best practice recommendations identified in the research literature. However, priority rules such as Most Total Successors (MTS) and Resource Scheduling Method (RSM) were used "very often" by half of the respondents when better performing priority rules were available. Through experience, project managers learn to manage multiple projects under resource constraints. Best practice literature can assist project managers in priority setting by recommending the most appropriate priority given resource constraints and project characteristics. There is room for improvement in managing multiple projects.

    This pilot study examined the use of Reiki prior to colonoscopy to reduce anxiety and minimize intraprocedure medications compared with usual care. A prospective, nonblinded, partially randomized patient preference design was employed using 21 subjects undergoing colonoscopy for the first time. Symptoms of anxiety and pain were assessed using a Likert-type scale. Between-group differences were assessed using chi-square analyses and analysis of variance. There were no differences between the control (n = 10) and experimental (n = 11) groups on age (mean = 58 years, SD = 8.5) and gender (53% women). The experimental group had higher anxiety (4.5 vs. 2.6, p = .03) and pain (0.8 vs. 0.2, p = .42) scores prior to colonoscopy. The Reiki intervention reduced mean heart rate (-9 beats/minute), systolic blood pressure (-10 mmHg), diastolic blood pressure (-4 mmHg), and respirations (-3 breaths/minute). There were no between-group differences on intraprocedure medication use or postprocedure physiologic measures. Although the experimental group patients had more symptoms, they did not require additional pain medication during the procedure, suggesting that (1) anxious people may benefit from an adjunctive therapy; (2) anxiety and pain are decreased by Reiki therapy for patients undergoing colonoscopy, and (3) additional intraprocedure pain medication may not be needed for colonoscopy patients receiving Reiki therapy. This pilot study provided important insights in preparation for a rigorous, randomized, controlled clinical trial.

  5. A study of pilot modeling in multi-controller tasks

    1972-01-01

    A modeling approach, which utilizes a matrix of transfer functions to describe the human pilot in multiple input, multiple output control situations, is studied. The approach used was to extend a well established scalar Wiener-Hopf minimization technique to the matrix case and then study, via a series of experiments, the data requirements when only finite record lengths are available. One of these experiments was a two-controller roll tracking experiment designed to force the pilot to use rudder in order to coordinate and reduce the effects of aileron yaw. One model was computed for the case where the signals used to generate the spectral matrix are error and bank angle while another model was computed for the case where error and yaw angle are the inputs. Several anomalies were observed to be present in the experimental data. These are defined by the descriptive terms roll up, break up, and roll down. Due to these algorithm induced anomalies, the frequency band over which reliable estimates of power spectra can be achieved is considerably less than predicted by the sampling theorem.

    To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile. A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7). The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development. This pilot study indicates that the severity of dental caries is correlated with early childhood development. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Through data collection methods using a holistic approach that focuses on variables in a natural setting, qualitative research methods seek to understand participants' perceptions and interpretations. Common qualitative research methods include ethnography, phenomenology, grounded theory, and historic research. Another type of methodology that has a similar qualitative approach is case study research, which seeks to understand a phenomenon or case from multiple perspectives within a given real-world context.

    The Training for Health Equity Network (THEnet), a group of diverse health professional schools aspiring toward social accountability, developed and pilot tested a comprehensive evaluation framework to assess progress toward socially accountable health professions education. The evaluation framework provides criteria for schools to assess their level of social accountability within their organization and planning; education, research and service delivery; and the direct and indirect impacts of the school and its graduates, on the community and health system. This paper describes the pilot implementation of testing the evaluation framework across five THEnet schools, and examines whether the evaluation framework was practical and feasible across contexts for the purposes of critical reflection and continuous improvement in terms of progress towards social accountability. In this pilot study, schools utilized the evaluation framework using a mixed method approach of data collection comprising of workshops, qualitative interviews and focus group discussions, document review and collation and analysis of existing quantitative data. The evaluation framework allowed each school to contextually gather evidence on how it was meeting the aspirational goals of social accountability across a range of school activities, and to identify strengths and areas for improvement and development. The evaluation framework pilot study demonstrated how social accountability can be assessed through a critically reflective and comprehensive process. As social accountability focuses on the relationship between health professions schools and health system and health population outcomes, each school was able to demonstrate to students, health professionals, governments, accrediting bodies, communities and other stakeholders how current and future health care needs of populations are addressed in terms of education, research, and service learning.

    Full Text Available The death of a child is difficult to the bereaved parents. Literature had associated the loss with marriage disruption. The issues on that the difficulties to communicate, gender-related coping mechanisms and sexual need were discussed as reasons for bereaved parents to have conflict in their relationship. However there is limited knowledge about this issue. A pilot study has been conducted among six bereaved parents. The bereaved parents were Malaysian Muslim bereaved parents. They were interviewed individually to explore the challenges or conflicts that they had experienced after the death of their child. This study revealed that there were situations which bereaved parents described as having difficulties in their relationship. However, this study also revealed that the mutual understanding and respect to each other are the most of important components for bereaved parents to maintain their relationship post-loss. This study suggested the importance of suggesting couple counselling to bereaved parents after the death of their child.

    In the field of Neurology good clinical reasoning skills are essential for successful diagnosing and treatment. Team-based learning (TBL), an active learning and small group instructional strategy, is a promising method for fostering these skills. The aim of this pilot study was to examine the effects of a supplementary TBL-class on students' clinical decision-making skills. Fourth- and fifth-year medical students participated in this pilot study (static-group comparison design). The non-treatment group (n = 15) did not receive any additional training beyond regular teaching in the neurology course. The treatment group (n = 11) took part in a supplementary TBL-class optimized for teaching clinical reasoning in addition to the regular teaching in the neurology course. Clinical decision making skills were assessed using a key-feature problem examination. Factual and conceptual knowledge was assessed by a multiple-choice question examination. The TBL-group performed significantly better than the non-TBL-group (p = 0.026) in the key-feature problem examination. No significant differences between the results of the multiple-choice question examination of both groups were found. In this pilot study participants of a supplementary TBL-class significantly improved clinical decision-making skills, indicating that TBL may be an appropriate method for teaching clinical decision making in neurology. Further research is needed for replication in larger groups and other clinical fields.

    A faculty team developed the 4-week Recovery-Based Interprofessional Distance Education (RIDE) rotation for graduate students in their disciplines. The evaluation team identified the Team Development Measure (TDM) as a potential alternative to reflect team development during the RIDE rotation. The TDM, completed anonymously online, was piloted on the second student cohort (N = 18) to complete the RIDE rotation. The overall pretest mean was 60.73 points (SD = 11.85) of a possible 100 points, indicating that students anticipated their RIDE team would function at a moderately high level during the 4-week rotation. The overall posttest mean, indicating student perceptions of actual team functioning, was 72.71 points (SD = 23.31), an average increase of 11.98 points. Although not statistically significant, Cohen's effect size (d = 0.43) indicates an observed difference of large magnitude. No other published work has used the TDM as a pre-/posttest measure of team development. The authors believe the TDM has several advantages as a measure of student response to interprofessional education offerings, particularly in graduate students with prior experience on health care teams. Further work is needed to validate and extend the findings of this pilot study. [Journal of Psychosocial Nursing and Mental Health Services, 56(4), 18-22.]. Copyright 2018, SLACK Incorporated.

    This article reports a pilot study of the potential benefits of a sustained programme of singing activities on the musical behaviours and hearing acuity of young children with hearing impairment (HI). Twenty-nine children (n=12 HI and n=17 NH) aged between 5 and 7 years from an inner-city primary school in London participated, following appropriate ethical approval. The predominantly classroom-based programme was designed by colleagues from the UCL Institute of Education and UCL Ear Institute in collaboration with a multi-arts charity Creative Futures and delivered by an experienced early years music specialist weekly across two school terms. There was a particular emphasis on building a repertoire of simple songs with actions and allied vocal exploration. Musical learning was also supported by activities that drew on visual imagery for sound and that included simple notation and physical gesture. An overall impact assessment of the pilot programme embraced pre- and post-intervention measures of pitch discrimination, speech perception in noise and singing competency. Subsequent statistical data analyses suggest that the programme had a positive impact on participant children's singing range, particularly (but not only) for HI children with hearing aids, and also in their singing skills. HI children's pitch perception also improved measurably over time. Findings imply that all children, including those with HI, can benefit from regular and sustained access to age-appropriate musical activities.

    A pilot study was conducted to analyze the benefits of using interactive technology with external assessors and graduating senior nursing students during Senior Nurse Leadership Assessment Day at the University of Central Missouri. The primary aim was to determine whether videoconferencing technology would promote recruitment and retention of professional nurse external assessors without compromising student learning. Among the issues discussed are the advantages and disadvantages of using interactive videoconferencing technology in education and the influence of external assessors in nursing education. The study results indicate that interactive videoconferencing is an effective, accepted format for educational opportunities such as Senior Nurse Leadership Assessment Day, based on the lived experiences of the study participants. In addition, the results demonstrate that interactive videoconferencing does not compromise student learning or assessment by external assessors.

    There is a recognized need to include patients in setting research priorities. Research priorities identified by people with a stoma are rarely elicited. To improve the quality of life of people with a stoma through use of evidence-based practice based on research priorities set by patients. Online pilot survey publicized in 2016 via United Kingdom stoma charities. People ranked nine stoma-related quality of life topics in order of research priority. People 16 years of age and over who currently have or have had a stoma for treatment for any medical condition. Distributions of the priority scores for each of the nine research topics were examined. Group differences were explored using either the Mann-Whitney U-test or the Kruskal-Wallis test depending on the number of groups. In total, 225 people completed the survey. The most important research priority was pouch leak problems and stoma bag/appliance problems followed by hernia risk. There were statistically significant differences in ranking research priorities between males and females, age, underlying disease that led to a stoma, stoma type and length of time with a stoma. People with a stoma are willing to engage in and set research priorities. The results should contribute towards future research about setting the research agenda for the study of stoma-related concerns that impact quality of life. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    The CCPR Pilot Comparison on spectral responsivity in the 10 nm to 20 nm spectral range was carried out within the framework of the CIPM Mutual Recognition Arrangement by three laboratories: PTB (Germany), NIST (USA), and NMIJ/AIST (Japan) with PTB acting as the central and reporting laboratory. All participating laboratories used monochromatized synchrotron radiation. PTB and NIST used a cryogenic radiometer as the primary standard detector and NMIJ, an ionization chamber with extrapolation by a wavelength-independent detector. The aim of the pilot comparison was to check the accuracy of the radiometric scale of spectral responsivity in the short wavelength EUV spectral range which has recently gained in technological importance. The wavelengths of measurement were from 11.5 nm to 20 nm in 0.5 nm steps and additionally 12.2 nm. The comparison was carried out through the calibration of a group of transfer standard detectors. Two sets of three diodes of types AXUV and SXUV from International Radiation Detectors, Inc. were used for the comparison. The comparison had the form of a star comparison: Pilot-lab A-pilot-lab B-pilot, PTB acting as the pilot laboratory. All results were communicated directly to the pilot laboratory. The report describes in detail the measurements made at PTB and summarizes the reports submitted by the participants. Measurements carried out by the pilot laboratory before and after the circulation of the detectors proved that the stability of the detectors was sufficient for the comparison. For the type AXUV detectors, however, changes in their responsivity contributed to the uncertainty of the comparison. Measurement results from participants and their associated uncertainties were analyzed in this report according to the Guidelines for CCPR Comparison Report Preparation. The uncertainty contributions were separated, as to whether they are wavelength dependent or not. All bilateral DoE are well within the respective k = 2 expanded uncertainty

    OBJECTIVES: The objectives of the pilot study were to modify existing psychological first aid (PFA) materials so they would be appropriate for use with institutionalized elders, evaluate the feasibility of using nursing home staff to deliver the intervention to residents, and solicit feedback from residents about the intervention. The STORM Study, an acronym for "services for treating older residents' mental health", is the first step in the development of an evidence-based disaster mental health intervention for this vulnerable and underserved population. METHOD: Demographic characteristics were collected on participating residents and staff. Program evaluation forms were completed by staff participants during the pilot test and nurse training session. Staff and resident discussion groups were conducted during the pilot test to collect qualitative data on the use of PFA in nursing homes. RESULTS: Results demonstrate the feasibility of the PFA program to train staff to provide residents with PFA during disasters. CONCLUSIONS: Future research should focus on whether PFA improves coping and reduces stress in disaster exposed nursing home residents.

    Full Text Available Abstract Background Tobacco smoking is a serious risk to health: several therapies are available to assist those who wish to stop. Smokers who approach publicly funded stop-smoking clinics in the UK are currently offered nicotine replacement therapy (NRT or bupropion, and group behaviour therapy, for which there is evidence of effectiveness. Acupuncture and acupressure are also used to help smokers, though a systematic review of the evidence of their effectiveness was inconclusive. The aim of this pilot project was to determine the feasibility of a study to test acupressure as an adjunct to one anti-smoking treatment currently offered, and to inform the design of the study. Methods An open randomised controlled pilot study was conducted within the six week group programme offered by the Smoking Advice Service in Plymouth, UK. All participants received the usual treatment with NRT and group behavioural therapy, and were randomised into three groups: group A with two auricular acupressure beads, group B with one bead, and group C with no additional therapy. Participants were taught to press the beads when they experienced cravings. Beads were worn in one ear for four weeks, being replaced as necessary. The main outcome measures assessed in the pilot were success at quitting (expired CO ≤ 9 ppm, the dose of NRT used, and the rating of withdrawal symptoms using the Mood and Symptoms Scale. Results From 49 smokers attending four clinics, 24 volunteered to participate, 19 attended at least once after quitting, and seven remained to the final week. Participants who dropped out reported significantly fewer previous quit attempts, but no other significant differences. Participants reported stimulating the beads as expected during the initial days after quitting, but most soon reduced the frequency of stimulation. The discomfort caused by the beads was minor, and there were no significant side effects. There were technical problems with adhesiveness of

    To test two interventions to reduce interleukin (IL)-6 levels, an indicator of low-grade chronic inflammation and an independent risk factor for impaired mobility and slow walking speed in older adults. The ENabling Reduction of low-Grade Inflammation in SEniors (ENRGISE) Pilot Study was a multicenter, double-blind, placebo-controlled randomized pilot trial of two interventions to reduce IL-6 levels. Five university-based research centers. Target enrollment was 300 men and women aged 70 and older with an average plasma IL-6 level between 2.5 and 30 pg/mL measured twice at least 1 week apart. Participants had low to moderate physical function, defined as self-reported difficulty walking one-quarter of a mile or climbing a flight of stairs and usual walk speed of less than 1 m/s on a 4-m usual-pace walk. Participants were randomized to losartan, omega-3 fish oil (ω-3), combined losartan and ω-3, or placebo. Randomization was stratified depending on eligibility for each group. A titration schedule was implemented to reach a dose that was safe and effective for IL-6 reduction. Maximal doses were 100 mg/d for losartan and 2.8 g/d for ω-3. IL-6, walking speed over 400 m, physical function (Short Physical Performance Battery), other inflammatory markers, safety, tolerability, frailty domains, and maximal leg strength were measured. Results from the ENRGISE Pilot Study will provide recruitment yields, feasibility, medication tolerance and adherence, and preliminary data to help justify a sample size for a more definitive randomized trial. The ENRGISE Pilot Study will inform a larger subsequent trial that is expected to have important clinical and public health implications for the growing population of older adults with low-grade chronic inflammation and mobility limitations. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    The fluid-dynamic behavior of a circulating fluidized bed pilot plant for oxyfuel combustion was studied in a cold flow model, down-scaled using Glicksman's criteria. Pressures along the unit and the global circulation rate were used for characterization. The analysis of five operating parameters and their influence on the system was carried out; namely, total solids inventory and the air velocity of primary, secondary, loop seal and support fluidizations. The cold flow model study shows that the reactor design allows stable operation at a wide range of fluidization rates, with results that agree well with previous observations described in the literature.

    The objective of this study was to obtain measurement of cutaneous tissue perfusion central and peripheral venous pressure, and esophageal and abdominal pressure in human test subjects during parabolic flight. Hemodynamic data recorded during SLS-I and SLS-2 missions have resulted in the paradoxical finding of increased cardiac stroke volume in the presence of a decreased central venous pressure (CVP) following entry in weightlessness. The investigators have proposed that in the absence of gravity, acceleration-induced peripheral vascular compression is relieved, increasing peripheral vascular capacity and flow while reducing central and peripheral venous pressure, This pilot study seeks to measure blood pressure and flow in human test subjects during parabolic flight for different postures.

    Full Text Available Anxiety is an important factor in foreign language learning. Very few studies have been done on English as a Foreign Language (EFL Saudi students in listening classes. Therefore, this pilot study was aimed at exploring the causes of listening comprehension anxiety from EFL Saudi learners’ perspectives at Majmaah University, Saudi Arabia. The pilot study involved two students who were selected based on the following criteria: 1 Only Saudi male undergraduate students who enrolled in Preparatory Year Program (PYP at Majmaah University would be involved in this study, 2 The students who had studied or lived in native English speaking countries would be excluded. The researcher used pseudonyms to refer to the participants as Mohammad and Ismail. This study employed a qualitative case study research design. The data were collected through Semi-structured interviews with the participants. The interview sessions were audiotaped and transcribed. The results show that the participants experienced a high level of anxiety when doing the listening comprehension tasks. Three main causes of listening comprehension anxiety emerged from this study: 1 the problematic nature of listening comprehension, 2 the classroom atmosphere, and 3 the low English proficiency of the students.

    While health literacy has gained notice on a global stage, the initial focus on seeking associations with medical conditions may have overlooked its impact across generations. Adolescent health literacy, specifically in dentistry, is an underexplored area despite the significance of this formative stage on an individual's approach to healthy lifestyles and behaviors. The aim is to conduct a pilot study to evaluate the efficacy of three major social media outlets - Twitter, Facebook, and YouTube - in supporting adolescents' oral health literacy (OHL) education. A random sample of 22 adolescents (aged 14-16 years) from an English-medium international school in Hong Kong provided informed consent. Sociodemographic information, including English language background, social media usage, and dental experience were collected via a questionnaire. A pre- and post-test of OHL (REALD-30) was administered by two trained, calibrated examiners. Following pre-test, participants were randomly assigned to one of three social media outlets: Twitter, Facebook, or YouTube. Participants received alerts posted daily for 5 consecutive days requiring online accessing of modified and original OHL education materials. One-way ANOVA ( analysis of variance) was used to compare the mean difference between the pre- and the post-test results among the three social media. No associations were found between the social media allocated and participants' sociodemographics, including English language background, social media usage, and dental experience. Of the three social media, significant differences in literacy assessment scores were evident for participants who received oral health education messages via Facebook (P=.02) and YouTube (P=.005). Based on the results of the pilot study, Facebook and YouTube may be more efficient media outlets for OHL promotion and education among adolescent school children when compared to Twitter. Further analyses with a larger study group is warranted.

    Recently, attempts have made to use radiotherapy in combination with chemotherapy in various solid tumors including cervical cancer. Twenty-four patients with locally advanced cervical cancer were treated with concurrent Carboplatin (16-24 mg/m 2 /day) or Nedaplatin (20 mg/m 2 /week) and conventional radiotherapy. Of 13 evaluable patients, there were nine complete responders and four partial responders. There was no renal damage or grade 4 hematological toxicity. Gastrointestinal adverse reactions were mild. One patient had grade 3 dermatologic toxicity after delayed radiation therapy. This pilot study suggests that daily Carboplatin or weekly Nedaplatin administered with standard radiation therapy is safe, well-tolerated, and thus may be useful as a radiation sensitizer in the treatment of locally advanced cervical cancer.

    Full Text Available Many objective or subjective factors influence the decision to open a business. The most important factors are: the existence of an adequate opportunity or a market, perception that starting a business could be difficult because of bureaucracy, financial barriers or the need to acquire new skills, a lack of money, etc. Also, entrepreneurial behavior is generally influenced by socio-economic status of the family of origin [1]. Thus, children from wealthy families have the “competitive advantage” to receive an education appropriate for managing a business and of course have the necessary financial resources and its start [2]. However, abilities of every individual can “correct’’ these benefits are completely eliminated/reduced exogenous barriers [3]. In this article I will present the results of a pilot study conducted in 2014 at Bucharest employees to observe their entrepreneurial behavior.

    This pilot study tested the influence of nutrition message framing on snack choice among kindergarteners. Three classrooms were randomly assigned to watch one of the following 60s videos: (a) a gain-framed nutrition message (i.e. the positive benefits of eating apples) (n=14); (b) a loss-framed message (i.e. the negative consequences of not eating apples) (n=18); or (c) a control scene (children playing a game) (n=18). Following this, the children were offered a choice between animal crackers and an apple for their snack. Among the children who saw one of the nutrition message videos, 56% chose apples rather than animal crackers; in the control condition only 33% chose apples. This difference was statistically significant (chi2=7.56, p<0.01). These results suggest that videos containing nutritional messages may have a positive influence on children's short-term food choices.

    Full Text Available Awareness of addictions in the Jewish community is becoming increasingly prevalent, and yet, a gap exists in the literature regarding addictions in this community. Knowledge about the prevalence of addictions within Jewish communities is limited; some believe that Jews cannot be affected by addictions. To address this gap, a pilot study was conducted to gather preliminary evidence relating to addictions and substance use in the Jewish community. Results indicate that a significant portion of the Jewish community knows someone affected by an addiction and that over 20% have a family history of addiction. Future research needs are discussed.

    Attention problems are one of the most pronounced and documented consequences of very preterm birth (gestational age ≤32 weeks). However, up to now, there is no research published on suitable interventions at school age aimed to overcome these problems. Research in this population did show that executive functions (EFs) are strongly associated with inattention. BrainGame Brian is a newly developed computerized training, in which, in 25 training sessions, the core EFs, including working memory, impulse control, and cognitive flexibility, are trained. This pilot study aimed to examine the feasibility of studying BrainGame Brian in very preterm-born children with attention problems. Pilot feasibility intervention study with one baseline and one follow-up assessment. Feasibility was measured by the participation rate, dropout rate, and user experiences with regard to effort, training characteristics, and recommendation to others. From a larger cohort study, 15 very preterm-born children at age 10 years with parent-reported attention problems on the Child Behavior Checklist/6-18 years were invited to participate in this pilot study. BrainGame Brian was performed for a period of 6 weeks. Training outcome measures included visual working memory, impulse control, cognitive flexibility, speed variability, and parent-rated attention, for which pre- and post-training differences were examined at the group level by the Wilcoxon signed-rank test as well as for each individual child separately by the reliable change index. Twelve of 15 children and their parents agreed to participate and 11 children successfully completed BrainGame Brian in the 6-week period. Parents were positive about training characteristics and lack of interference with schooling, but scored the effort as high. We found clinically significant changes in visual working memory and speed variability in post-training assessments. BrainGame Brian is a feasible intervention for very preterm-born children with

    Germline genomic testing is increasingly used in research to identify genetic causes of disease, including cancer. However, there is evidence that individuals who are notified of clinically actionable research findings have difficulty making informed decisions regarding uptake of genetic counseling for these findings. This study aimed to produce and pilot test a decision aid to assist participants in genomic research studies who are notified of clinically actionable research findings to make informed choices regarding uptake of genetic counseling. Development was guided by published literature, the International Patient Decision Aid Standards, and the expertise of a steering committee of clinicians, researchers, and consumers. Decision aid acceptability was assessed by self-report questionnaire. All 19 participants stated that the decision aid was easy to read, clearly presented, increased their understanding of the implications of taking up research findings, and would be helpful in decision-making. While low to moderate levels of distress/worry were reported after reading the booklet, a majority of participants also reported feeling reassured. All participants would recommend the booklet to others considering uptake of clinically actionable research findings. Results indicate the decision aid is acceptable to the target audience, with potential as a useful decision support tool for genomic research participants.

    Many seriously ill and frail inpatients receive potentially inappropriate or harmful medications and do not receive medications for symptoms of advanced illness. We developed and piloted an interprofessional Medication Rationalization (MERA) approach to deprescribing inappropriate medications and prescribing appropriate comfort medications. We conducted a single-centre pilot study of inpatients at risk of 6-month mortality from advanced age or morbidity. The MERA team reviewed the patients' medications and made recommendations on the basis of guidelines. We measured end points for feasibility, acceptability, efficiency and effectiveness. We enrolled 61 of 115 (53%) eligible patients with a mean age of 79.6 years (standard deviation [SD] 11.7 yr). Patients were taking an average of 11.5 (SD 5.2) medications before admission and had an average of 2.1 symptoms with greater than 6/10 severity on the revised Edmonton Symptom Assessment System. The MERA team recommended 263 medication changes, of which 223 (85%) were accepted by both the medical team and the patient. MERA team's recommendations resulted in the discontinuation of 162 medications (mean 3.1 per patient), dose changes for 48 medications (mean 0.9 per patient) and the addition of 13 medications (mean 0.2 per patient). Patients who received the MERA intervention stopped significantly more inappropriate medications than similar non-MERA comparison patients for whom data were collected retrospectively (3.1 v. 0.9 medications per patient, p < 0.01). The MERA approach was highly acceptable to patients and medical team members. The MERA intervention is feasible, acceptable, efficient and possibly effective for changing medication use among seriously ill and frail elderly inpatients. Scalability and effectiveness may be improved through automation and integration with medication reconciliation programs. Copyright 2018, Joule Inc. or its licensors.

  6. Research ethics across the 49th parallel: the potential value of pilot testing "equivalent protections" in Canadian research institutions.

    Science.gov (United States)

    Lavery, James V; McDonald, Michael; Meslin, Eric M

    2005-01-01

    Canada and the United States share the world's largest trade partnership and an increasing concern about divergent regulatory approaches to common industries. Canadian research institutes receive more research funding from the U.S. National Institutes of Health than any other country, much of it to fund multi-centre and collaborative research between the two countries. Because of these close economic and research ties, and the extensive similarities between the two countries in the review and oversight of ethics in human subjects research, we propose that Canada would be an ideal country for a pilot-test of the feasibility of "equivalent protections," a U.S. regulation that permits comparison of protections for human subjects between institutions in the two countries. The "equivalent protections" has been advocated by various bodies in the United States as a potentially beneficial mechanism for improving oversight of foreign trials. As well, we argue that "equivalent protections" could prove to be valuable for Canada in five specific ways: (1) by potentially reducing administrative burden on Canadian research institutions administering U.S. federal research funding; (2) by creating symbolic value of an explicit recognition by the United States that procedures normally followed for the protection of human subjects in Canadian research institutions are at least equivalent to those provided by the U.S. regulations; (3) by lowering the opportunity cost of investing in research in Canada; (4) by affording Canada an opportunity to enhance its leadership role in international research by offering an alternative to the U.S. regulatory model for the protection of human subjects; and (5) by providing a model for how the idea of equivalent protections might be addressed for research funded by Canadian agencies but conducted in other countries.

    The objective of this study was to determine the prevalence of Staphylococcus-contaminated stethoscopes belonging to emergency department (ED) staff and to identify the proportion of these that were Staphylococcus aureus or methicillin-resistant Staphylococcus aureus (MRSA). We conducted a prospective observational cohort study of bacterial cultures from 100 ED staff members' stethoscopes at three EDs. Study participants were asked to complete a questionnaire. Fifty-four specimens grew coagulase-negative staphylococci and one grew methicillin-susceptible S. aureus. No MRSA was cultured. Only 8% of participants, all of whom were nurses, reported cleaning their stethoscope before or after each patient assessment. Alcohol-based wipes were most commonly used to clean stethoscopes. A lack of time, being too busy, and forgetfulness were the most frequently reported reasons for not cleaning the stethoscope in the ED. This study indicates that although stethoscope contamination rates in these EDs are high, the prevalence of S. aureus or MRSA on stethoscopes is low.

    This study falls within the framework of the incorporation of quantitative risk assessment to the activities planned for the ESA-HERMES project (ESA/ CNES). The main objective behind the study was the analysis and evaluation of the potential contribution of so-called probabilistic or quantitative safety analysis to the optimization of the safety development process for the systems carrying out the safety functions required by the new and complex HERMES Space Vehicle. For this purpose, a pilot study was considered a good start in quantitative safety assessments (QSA), as this approach has been frequently used in the past to establish a solid base in large-scale QSA application programs while avoiding considerable economic risks. It was finally decided to select the HERMES docking/berthing system with Man Tender Free Flyer as the case-study. This report describes the different steps followed in the study, along with the main insights obtained and the general conclusions drawn from the study results. (author)

    Systematic literature reviews identify, select, appraise, and synthesize relevant literature on a particular topic. Typically, these reviews examine primary studies based on similar methods, e.g., experimental trials. In contrast, interest in a new form of review, known as mixed studies review (MSR), which includes qualitative, quantitative, and mixed methods studies, is growing. In MSRs, reviewers appraise studies that use different methods allowing them to obtain in-depth answers to complex research questions. However, appraising the quality of studies with different methods remains challenging. To facilitate systematic MSRs, a pilot Mixed Methods Appraisal Tool (MMAT) has been developed at McGill University (a checklist and a tutorial), which can be used to concurrently appraise the methodological quality of qualitative, quantitative, and mixed methods studies. The purpose of the present study is to test the reliability and efficiency of a pilot version of the MMAT. The Center for Participatory Research at McGill conducted a systematic MSR on the benefits of Participatory Research (PR). Thirty-two PR evaluation studies were appraised by two independent reviewers using the pilot MMAT. Among these, 11 (34%) involved nurses as researchers or research partners. Appraisal time was measured to assess efficiency. Inter-rater reliability was assessed by calculating a kappa statistic based on dichotomized responses for each criterion. An appraisal score was determined for each study, which allowed the calculation of an overall intra-class correlation. On average, it took 14 min to appraise a study (excluding the initial reading of articles). Agreement between reviewers was moderate to perfect with regards to MMAT criteria, and substantial with respect to the overall quality score of appraised studies. The MMAT is unique, thus the reliability of the pilot MMAT is promising, and encourages further development. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Methodologically, to assess the feasibility of participant recruitment and retention, as well as missing data in studying mental disorder among children newly diagnosed with chronic physical conditions (ie, multimorbidity). Substantively, to examine the prevalence of multimorbidity, identify sociodemographic correlates and model the influence of multimorbidity on changes in child quality of life and parental psychosocial outcomes over a 6-month follow-up. Prospective pilot study. Two children's tertiary-care hospitals. Children aged 6-16 years diagnosed in the past 6 months with one of the following: asthma, diabetes, epilepsy, food allergy or juvenile arthritis, and their parents. Response, participation and retention rates. Child mental disorder using the Mini International Neuropsychiatric Interview at baseline and 6 months. Child quality of life, parental symptoms of stress, anxiety and depression, and family functioning. All outcomes were parent reported. Response, participation and retention rates were 90%, 83% and 88%, respectively. Of the 50 children enrolled in the study, the prevalence of multimorbidity was 58% at baseline and 42% at 6 months. No sociodemographic characteristics were associated with multimorbidity. Multimorbidity at baseline was associated with declines over 6 months in the following quality of life domains: physical well-being, β=-4.82 (-8.47, -1.17); psychological well-being, β=-4.10 (-7.62, -0.58) and school environment, β=-4.17 (-8.18, -0.16). There was no association with parental psychosocial outcomes over time. Preliminary evidence suggests that mental disorder in children with a physical condition is very common and has a negative impact on quality of life over time. Based on the strong response rate and minimal attrition, our approach to study child multimorbidity appears feasible and suggests that multimorbidity is an important concern for families. Methodological and substantive findings from this pilot study have

    To pilot the development of a scale measuring the quality of audit projects through audit project reports. Statements about clinical audit projects were selected from existing instruments, assessing the quality of clinical audit projects, to form a Likert scale. The audit facilitators were based in Scottish health boards and trusts. The participants were audit facilitators known to have over 2 years experience of supporting clinical audit. The response at first test was 11 out of 14 and at the second test it was 27 out of 46. The draft scale was tested by 27 audit facilitators who expressed their strength of agreement or disagreement with each statement for three reports. Validity was assessed by test-re-test, item-total, and total-global indicator correlations. Of the 20 statements, 15 had satisfactory correlations with scale totals. Scale totals had good correlations with global indicators. Test-re-test correlation was modest. The wide range of responses means further research is needed to measure the consistency of audit facilitators' interpretations, perhaps comparing a trained group with an untrained group. There may be a need for a separate scale for reaudits. Educational impact is distinct from project impact generally. It may be more meaningful to treat the selection of projects and aims, methodology and impact separately as subscales and take a project profiling approach rather than attempting to produce a global quality index.

    As a result of digitalization, data is available about almost every aspect of our lives. Personal data collected by individuals themselves or stored by organizations interacting with people is known as a digital footprint. The purpose of this study was to identify prerequisites for collecting and using digital data that could be valuable for health data analytics and new health services. Researchers and their contacts involved in a nationwide research project focusing on digital health in Finland were asked to participate in a pilot study on collecting their own personal data from various organizations of their own choice, such as retail chains, banks, insurance companies, and healthcare providers. After the pilot, a qualitative inquiry was adopted to collect semi-structured interview data from twelve active participants in the pilot. Interviews comprised themes such as the experiences of collecting personal data, as well as the usefulness of the data in general and for the participants themselves. Interview data was then analyzed thematically. Even if the participants had an academic background and were highly motivated to collect and use their data, they faced many challenges, such as quite long delays in the provision of the data, and the unresponsiveness of some organizations. Regarding the usefulness of the acquired personal data, our results show that participants had high expectations, but they were disappointed with the small amount of data and its irrelevant content. For the most part, the data was not in a format that would be useful for health data analytics and new health services. Participants also found that there were actual mistakes in their health data reports. The study revealed that collecting and using digital footprint data, even by knowledgeable individuals, is not an easy task. As the usefulness of the acquired personal health data mainly depended on its form and usability for services or solutions relevant to an individual, rather than on

    International studies have shown that some 60% of paramedics have experienced physical violence in the workplace, and between 21-78% have experienced verbal abuse. To date, there is no Australian literature describing Australian paramedics' experience of workplace violence. To identify the percentage of paramedics who had experienced six different forms of workplace violence. A questionnaire was developed to explore paramedics' experience of workplace violence. Six forms of violence were included: verbal abuse, property damage or theft, intimidation, physical abuse, sexual harassment, and sexual assault. The questionnaire also included a series of demographic questions. The questionnaire was piloted using a reference group and changes made accordingly. The questionnaire was distributed to 500 rural Victorian paramedics and 430 metropolitan South Australian paramedics. Ethics approval was granted for this study. The overall response rate was 28%, with 75% being male and 25% female. The median age of respondents was 40.7 years, range 21-62 years. The median number of years experience as a paramedic was 14.3 years, range 6 months to 39 years. There were 87.5% of paramedics exposed to workplace violence. Verbal abuse was the most prevalent form of workplace violence (82%), with intimidation (55%), physical abuse (38%), sexual harassment (17%), and sexual assault (4%). This study lays the foundation for further studies investigating paramedic experience of workplace violence. This study demonstrates that workplace violence is prevalent for paramedics and highlights the need for prevention and education within the profession.

    2018-02-03

    Drawing on Pennock's theory of scientific virtues, we are developing an alternative curriculum for training scientists in the responsible conduct of research (RCR) that emphasizes internal values rather than externally imposed rules. This approach focuses on the virtuous characteristics of scientists that lead to responsible and exemplary behavior. We have been pilot-testing one element of such a virtue-based approach to RCR training by conducting dialogue sessions, modeled upon the approach developed by Toolbox Dialogue Initiative, that focus on a specific virtue, e.g., curiosity and objectivity. During these structured discussions, small groups of scientists explore the roles they think the focus virtue plays and should play in the practice of science. Preliminary results have shown that participants strongly prefer this virtue-based model over traditional methods of RCR training. While we cannot yet definitively say that participation in these RCR sessions contributes to responsible conduct, these pilot results are encouraging and warrant continued development of this virtue-based approach to RCR training.

    This pilot study compares the safety and efficacy of three treatments in reducing pain and improving fibromyalgia symptoms. This study was an 8-week prospective, single center feasibility study. Forty subjects were recruited from Solano, Sonoma, and Contra Costa counties of California in 2006-2009. Subjects were aged 18-65 and met the American College of Rheumatology (ACR) 1990 criteria for fibromyalgia. This study had three treatment arms: gabapentin only (900 mg/day), osteopathic manipulative medicine (OMM) only, and combined treatment of gabapentin plus OMM. OMM treatment was administered by advanced medical students for 30 min, once a week. The trial lasted for 8 weeks, which included 6 weeks of treatment plus initial and final visits. Key outcome measures included Wong-Baker FACES Pain Rating Scale (WBF), Clinical Global Impression of Health (CGI), Fibromyalgia Impact Questionnaire (FIQ), and number of tender points. Twenty-nine subjects completed the trial; 8 subjects received gabapentin only, 11 patients received OMM only, and 10 patients received gabapentin plus OMM. Subjects receiving OMM alone and subjects receiving the combined treatment of OMM and gabapentin displayed clinical improvements based on WBF (p treatment and gabapentin are safe and clinically efficacious treatment of pain and other constitutional and somatic symptoms associated with fibromyalgia. A larger trial using the new ACR 2010 Fibromyalgia criteria is needed to confirm these findings.

    Attention has been focused on the issue of radon in drinking water by a European Commission recommendation proposing that surveys should be undertaken in Member States to determine the scale and nature of exposures caused by radon in domestic drinking water supplies. The Commission recommends 1000 Bq/l as the radon activity concentration in private drinking water supplies above which remedial action to reduce the concentration should be taken. The logic behind the proposed action level is that it would broadly correspond to the risk posed to an individual from exposure to radon in the home at the current Reference Level of 200 Bq/m3 in air. A pilot study to assess the distribution and concentrations of radon in private ground water supplies was recently completed in Co. Wicklow. County Wicklow was selected for the study primarily on the basis that the underlying geology is predominantly granite with elevated uranium content. Furthermore, there is an estimated 1200 to 5000 private ground water supplies in use in the county and high radon activity concentrations in air in a significant number of dwellings have previously been predicted. As part of the pilot study, a number of scientific issues were addressed in order to underpin the results obtained and these are also discussed in the report. Radon activity concentrations were measured in the private ground water supplies of 166 houses in Co. Wicklow. In all cases the ground water was the principal source of drinking water for the house occupants. Four supplies had activity concentrations in excess of the Recommended EC action level of 1000 Bq/l, fifteen had activity concentrations between 500 and 1000 Bq/l, 51 were between 100 and 500 Bq/l and 96 had activity concentrations below 100 Bq/l. The doses estimated for the ingestion of radon bearing water vary significantly with the quantity of drinking water consumed and the degree to which the water has been processed prior to consumption.

    This project incorporates two related research projects directed toward understanding respiratory carcinogenesis in radon-exposed former uranium miners. The first project involved a continuation of the tissue resource of lung cancer cases from former underground uranium miners and comparison cases from non-miners. The second project was a pilot study for a proposed longitudinal study of respiratory carcinogenesis in former uranium miners. The objectives including facilitating the investigation of molecular changes in radon exposed lung cancer cases, developing methods for prospectively studying clinical, cytologic, cytogenetic, and molecular changes in the multi-event process of respiratory carcinogenesis, and assessing the feasibility of recruiting former uranium miners into a longitudinal study that collected multiple biological specimens. A pilot study was conducted to determine whether blood collection, induced sputum, bronchial brushing, washings, and mucosal biopsies from participants at two of the hospitals could be included efficiently. A questionnaire was developed for the extended study and all protocols for specimen collection and tissue handling were completed. Resource utilization is in progress at ITRI and the methods have been developed to study molecular and cellular changes in exfoliated cells contained in sputum as well as susceptibility factors.

    The U.S. Department of Energy (DOE) is sponsoring research, development, and deployment on light water reactor sustainability (LWRS), in which the Idaho National Laboratory (INL) is working closely with nuclear utilities to develop technologies and solutions to help ensure the safe operational life extension of current reactors. As technologies are introduced that change the operation of the plant, the LWRS pilot projects can help identify their best-advanced uses and help demonstrate the safety of these technologies. In early testing of operator performance given these emerging technologies will ensure the safety and usability of systems prior to large-scale deployment and costly verification and validation at the plant. The aim of these collaborations, demonstrations, and approaches are intended to lessen the inertia that sustains the current status quo of today's II&C systems technology, and to motivate transformational change and a shift in strategy to a long-term approach to II&C modernization that is more sustainable. Research being conducted under Pilot Project 1 regards understanding the conditions and behaviors that can be modified, either through process improvements and/or technology deployment, to improve the overall safety and efficiency of outage control at nuclear facilities. The key component of the research in this pilot project is accessing the delivery of information that will allow researchers to simulate the control room, outage control center (OCC) information, and plant status data. The simulation also allows researchers to identify areas of opportunity where plant operating status and outage activities can be analyzed to increase overall plant efficiency. For Pilot Project 3 the desire is to demonstrate the ability of technology deployment and the subsequent impact on maximizing the 'Collective Situational Awareness' of the various stakeholders in a commercial nuclear power plant.

    Up to 14% of children with epilepsy continue to experience seizures despite having appropriate medical therapy and develop medically refractory epilepsy (MRE). Assessing clinical outcomes and therapeutic efficacy in children with MRE undergoing palliative epilepsy surgery has been challenging because of the lack of a quantitative instrument capable of estimating the clinical status of these patients. The ideal instrument would at once consider seizure control, neurodevelopment, caregiver burden, and quality of life. The purpose of this study was to develop and pilot the Pediatric Refractory Epilepsy Questionnaire (PREQ), a quantitative instrument to assess the severity and individual burden of epilepsy in children with MRE undergoing palliative epilepsy treatments. The caregivers of 25 patients with MRE completed the PREQ and the Quality of Life in Childhood Epilepsy (QOLCE) measure and participated in a semistructured interview. Medical records of the patients were reviewed, an Early Childhood Epilepsy Severity Scale (E-CHESS) score was calculated, and a Global Assessment of Severity of Epilepsy (GASE) score was obtained for each patient. The initial PREQ was modified based on the analysis of responses, association with previously validated scales, comments from caregivers, and expertise of the PREQ panelists. Pediatric Refractory Epilepsy Questionnaire subscale scores were calculated based on clinical paradigm and compared with independent measures of seizure severity and quality of life. Significant correlations were observed between the seizure severity subscale and the GASE score (r=0.55) and between the mood subscale and the well-being score (r=0.61) on the QOLCE. Significant correlations were also observed between the caregiver rating of seizure severity and the GASE score (r=0.53), the social activity score (r=0.57), and the behavior score (r=0.43) on the QOLCE. Correlations between the caregiver rating of quality of life and the quality of life score (r=0

    Full Text Available Abstract Background Mindfulness means paying attention in the present moment, non-judgmentally, without commentary or decision-making. We report results of a pilot study designed to test the feasibility of using Mindfulness Based Stress Reduction (MBSR (with minor modifications as a smoking intervention. Methods MBSR instructors provided instructions in mindfulness in eight weekly group sessions. Subjects attempted smoking cessation during week seven without pharmacotherapy. Smoking abstinence was tested six weeks after the smoking quit day with carbon monoxide breath test and 7-day smoking calendars. Questionnaires were administered to evaluate changes in stress and affective distress. Results 18 subjects enrolled in the intervention with an average smoking history of 19.9 cigarettes per day for 26.4 years. At the 6-week post-quit visit, 10 of 18 subjects (56% achieved biologically confirmed 7-day point-prevalent smoking abstinence. Compliance with meditation was positively associated with smoking abstinence and decreases in stress and affective distress. Discussions and conclusion The results of this study suggest that mindfulness training may show promise for smoking cessation and warrants additional study in a larger comparative trial.

    Interactive lecture demonstrations (ILDs) have repeatedly shown to be effective tools for improving student achievement in the context of learning physics. As a first step toward systematic development of interactive lecture demonstrations in ASTRO 101, the introductory astronomy survey course, a systematic review of education research, describing educational computer simulations (ECSs) reveals that initial development requires a targeted study of how ASTRO 101 students respond to ECSs in the non-science majoring undergraduate lecture setting. In this project we have adopted the process by which ILDs were designed, pilot-tested, and successfully implemented in the context of physics teaching (Sokoloff & Thornton, 1997; Sokoloff & Thornton, 2004). We have designed the initial pilot-test set of ASTRO 101 ILD instructional materials relying heavily on ECSs. Both an instructor’s manual and a preliminary classroom-ready student workbook have been developed, and we are implementing a pilot study to explore their effectiveness in communicating scientific content, and the extent to which they might enhance students’ knowledge of and perception about astronomy and science in general. The study design uses a pre-/post-test quasi-experimental study design measuring students’ normalized gain scores, calculated as per Hake (1998) and Prather (2009), using a slightly modified version of S. Slater’s (2011) Test Of Astronomy STandards TOAST combined with other instruments. The results of this initial study will guide the iterative development of ASTRO 101 ILDs that are intended to both be effective at enhancing student achievement and easy for instructors to successfully implement.

    Breast cancer continues to represent a significant public health burden despite outstanding research advances regarding the molecular mechanisms of cancer biology, biomarkers for diagnostics and prognostic and therapeutic management of this disease. The studies of micro RNAs in breast cancer have underlined their potential as biomarkers and therapeutic targets; however most of these studies are still done on largely heterogeneous whole breast tissue samples. In this pilot study we have investigated the expression of four micro RNAs (miR-21, 145, 155, 92) known to be involved in breast cancer, in homogenous cell populations collected by laser capture microdissection from breast tissue section slides. Micro RNA expression was assessed by real time PCR, and associations with clinical and pathological characteristics were also explored. Our results have confirmed previous associations of miR-21 expression with poor prognosis characteristics of breast cancers such as high stage, large and highly proliferative tumors. No statistically significant associations were found with the other micro RNAs investigated, possibly due to the small sample size of our study. Our results also suggest that miR-484 could be a suitable endogenous control for data normalization in breast tissues, these results needing further confirmation by future studies. In summary, our pilot study showed the feasibility of detecting micro RNAs expression in homogenous laser captured microdissected invasive breast cancer samples, and confirmed some of the previously reported associations with poor prognostic characteristics of breast tumors.

    The Australian AEC has two research reactors at the Lucas Heights Research Establishment, a 10 HW DIDO class materials testing reactor, HIFAR, and a smaller 100kW reactor MOATA, which was recently upgraded from 10kW power level. Because of the HIFAR being some 20 years old, major renewal and repair programmes are necessary to keep it operational. To enable meeting projected increases in demand for radioisotopes, plans for a new reactor to replace the HIFAR have been made and the design criteria are described in the paper. (author)

    To investigate the level of oral cancer knowledge and awareness in a Spanish general population. A cross-sectional study using an anonymous questionnaire applied in the community to randomly selected laypersons. Sample size for the general population was determined by quota sampling, resulting in 1,041 individuals. A total of 1,707 pedestrians were approached (response: 61%). When the participants were asked about what cancers had they heard about (up to ten), oral cancer was mentioned in first place by 2% of the sample and by 22% in any order. When specifically asked about oral cancer, the percentage of interviewees who were familiar with it raised to 72%. Participants were also asked about the main signs or symptoms of oral cancer, and the most frequently (22%) mentioned as the first warning sign was a non-healing ulcer. Tobacco smoking generally was recognised as the most important (57%) risk factor for oral cancer. This pilot study revealed a low awareness of oral cancer, and a poor knowledge of its signs and symptoms and risk factors. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Task rotation is used to decrease the risk of workplace injuries and improve work satisfaction. To investigate the feasibility, benefits and challenges of implementing a task rotation schedule within an underground coalmine in NSW, Australia. A mixed method case control pilot study with the development and implementation of a task rotation schedule for 6 months with two work crews. A questionnaire including The Nordic Musculoskeletal Questionnaire, The Need for Recovery after Work Scale, and The Australian WHOQOL- BREF Australian Edition was used to survey workers at baseline, 3 and 6 months. A focus group was completed with the intervention crew and management at the completion of the study. In total, twenty-seven participants completed the survey. Significant improvements in the psychological and environmental domains of the WHOQOL-BREF questionnaire were found in the intervention crew. Musculoskeletal pain was highest in the elbow, lower back and knee, and fatigue scores improved, across both groups. The intervention crew felt 'mentally fresher', 'didn't do the same task twice in a row', and 'had more task variety which made the shift go quickly'. Task rotation was positively regarded, with psychological benefits identified. Three rotations during a 9-hour shift were feasible and practical in this environment.

    In order to assess the potential clinical utility of using thermoacoustic computer tomography (TCT) to image the breast, we conducted a retrospective pilot study of 78 patients. We recruited patients in three age groups (50 years). The study population was further segregated into normal and suspicious based on the results of the previous x-ray mammography and ultrasound. Image quality was evaluated qualitatively by consensus of two trained mammographers using a 4-point scale. The appearance of normal anatomy, cysts, benign disease and cancer was noted. Patients were also asked to rate the comfort of the TCT exam and to indicate a personal preference for x-ray mammography or TCT. Analysis of the data indicated that TCT image quality was dependent upon both patient age and breast density, improving with both increasing breast density and decreasing patient age. Fibrocystic disease was well seen, cysts appearing as areas of low RF absorption. Fibroadenomas did not demonstrate contrast enhancement with the exception of one patient with associated atypical hyperplasia. Cancer displayed higher RF absorption than surrounding tissues in 4/7 patients in whom cancer was confirmed, including one patient with a 7-mm ductal carcinoma in situ (DCIS).

    This pilot study aimed to gain empirical data on the social and economic impacts of child burns on children and parents, in the context of the outpatient setting. A questionnaire was completed by 52 parents of paediatric patients attending the burns outpatient department at Queen Victoria Hospital (QVH), East Grinstead, for at least the third time. Children's medical notes were used to extract demographic and medical data. Quantitative data was analyzed statistically and qualitative data was analyzed manually using content analysis. The financial burden related to the injury posed the greatest impact on parents, and was mainly associated with making the journey to the hospital, with lower income households being most affected. Self-employed parents and those who had to attend more than 6 hospital appointments also ran into difficulties. On the whole, there was not a considerable social impact on the burn-injured child, which may reflect the minor nature of burns in this study (mean depth partial thickness, median TBSA 1.0%). Parents were shown to perceive a greater impact from their child's burn injury than their child. Certain groups of parents were identified as requiring additional support following the burn injury.

    This study aimed to evaluate the validity of a surgically created interproximal periodontal defect in dogs. Surgery was performed in the interproximal area between the maxillary second and third premolars in two beagle dogs. Following an incision and reflection of the gingival flap, a 3-mm wide and 5-mm high defect was prepared surgically at the interproximal area. A thorough root planing was performed and the flap was coronally positioned and sutured. The contra-lateral area was served as the control with no surgical intervention. After 8 weeks of healing, the animals were killed and the defect was analysed histometrically and radiographically. The interproximal periodontal defect resembled a naturally occurring defect and mimicked a clinical situation. After healing, the defect showed limited bone (0.89±0.02mm) and cementum regeneration (1.50± 0.48mm). Within the limitations of this pilot study, the interproximal periodontal defect showed limited bone and cementum regeneration. Thus, it can be considered as a standardized, reproducible defect model for testing new biomaterials. © 2010 John Wiley & Sons A/S.

    Continuous personal monitoring is the benchmark for air pollution exposure assessment. Black carbon (BC) is a strong marker of primary combustion like vehicle and biomass emissions. There have been few studies that quantified daily personal BC exposure and the contribution that different microenvironments make to it. In this pilot study, we used a portable aethalometer to measure BC concentrations in an individual's breathing zone at 30-s intervals while he performed his usual daily activities. We used a GPS and time-activity diary to track where he spent his time. We performed twenty 24-h measurements, and observed an arithmetic mean daily exposure concentration of 603 ng/m3. We estimated that changing commute modes from bus to train reduced the 24-h mean BC exposure concentration by 29%. Switching from open windows to closed windows and recirculated air in a car led to a reduction of 32%. Living in a home without a wood-fired heater caused a reduction of 50% compared with a wood-heated home. Our preliminary findings highlight the potential utility of simple approaches to reduce a person's daily BC exposure.

    To observe and describe the positions and movements women choose while immersed in water during the first stage of labor. Descriptive, observational pilot study. A rural community hospital that provided hydrotherapy in labor. Women (N = 7) who intended to use hydrotherapy in labor were recruited prenatally from a midwife-managed practice. For 15 minutes of each hour during the first stage of labor, position and movements of the participants were observed and recorded on a laptop computer. The observational tool was developed for this study from a review of the literature and interviews with nursing experts; 435 observations were recorded. Women were free to choose when and how long to use hydrotherapy and had no restriction on their positions and movements. Only 3 of the 7 participants labored in the tub. Women demonstrated a greater range of positions and movements in the tub than in bed, both throughout labor and during late first-stage labor (7-10 cm of dilatation). Women had more contractions and made more rhythmic movements while in the tub than in bed. Hydrotherapy may encourage upright positions and movements that facilitate labor progress and coping, helping women avoid unnecessary interventions.

    We performed a pilot study to evaluate the safety and tolerability of bendamustine in patients with advanced hilar bile duct cancer and impaired liver function. Six patients with histologically proven, unresectable adenocarcinoma of the hilar bile duct were treated with bendamustine 140 mg/m intravenously on day 1 of the first cycle and with bendamustine 100 mg/m on days 1 and 2 of the second to fourth cycle. Treatment cycles were repeated every 21 days. Primary endpoint was the safety and tolerability of the treatment; secondary endpoints were response rate, time to progression and overall survival. Transient lymphopenia grade 3 occurred in all six patients. No other grade 3 or 4 toxicities were present. The most common nonhematologic toxicity was mouth dryness grade 2 in six patients. Three patients had stable disease. No partial or complete responses were observed. Median time to progression was 3.3 months; median overall survival was 6 months. Our study demonstrates that bendamustine can be safely administered in patients with hilar bile duct cancer and impaired liver function. A potential role of bendamustine in combination therapies for bile duct cancer will be a subject of further trials.

    Purpose Leadership has been identified as a key variable for the functioning of teams and as one of the main reasons for success or failure of team-based work systems. Pediatricians often function as team leaders in the resuscitation of a critically ill child. However, pediatric residents often report having little opportunity to perform in the role of team leader during residency. In order to gain more insight into leadership skills and behaviors, we classified leadership styles of pediatric residents during simulated emergencies. Methods We conducted a prospective quantitative study to investigate leadership styles used by pediatric residents during simulated emergencies with clinical deterioration of a child at a pediatric ward. Using videotaped scenarios of 48 simulated critical events among 12 residents, we were able to classify verbal and nonverbal communication into different leadership styles according to the situational leadership theory. Results The coaching style (mean 54.5%, SD 7.8) is the most frequently applied by residents, followed by the directing style (mean 35.6%, SD 4.1). This pattern conforms to the task- and role-related requirements in our scenarios and it also conforms to the concept of situational leadership. We did not find any significant differences in leadership style according to the postgraduate year or scenario content. Conclusion The model used in this pilot study helps us to gain a better understanding of the development of effective leadership behavior and supports the applicability of situational leadership theory in training leadership skills during residency.

    Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in "healthy" populations, little research exists in individuals with substance use disorders. This gap is notable considering the prominent role that choice and decision-making play in drug use. The purpose of this pilot study was to evaluate loss aversion in active cocaine users. Current cocaine users (N=38; 42% female) participated in this within-subjects laboratory pilot study. Subjects completed a battery of tasks designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Standardized loss aversion coefficients (λ) were compared to theoretically and empirically relevant normative values (i.e., λ=2). Compared to normative loss aversion coefficient values, a precise and consistent decrease in loss aversion was observed in cocaine users (sample λ≈1). These values were observed across drug and non-drug commodities as well as under certain and risky conditions. These data represent the first systematic study of loss aversion in cocaine-using populations and provide evidence for equal sensitivity to losses and gains or loss equivalence. Futures studies should evaluate the specificity of these effects to a history of cocaine use as well as the impact of manipulations of loss aversion on drug use to determine how this phenomenon may contribute to intervention development efforts.

    2002-01-01

    National Laboratory for Electrical Measurements has not yet developed its capability for the standardization of small electrical charge produced by DC, the IRD is trying to verify its standardization procedures of the electrical charge through a comparison programme. This subject was discussed with a major electrometer manufacturer that has offered to provide free of charge, three of their electrometer calibration standards for a pilot run. The model to be provided consists of four calibrated resistors and two calibrated capacitors, covering the charge/current range of interest. For producing charge or current a standard DC voltage must be applied to these components. Since practically all-modern electrometers measure using virtual ground, this methodology is viable. The IRD, in collaboration with the IAEA, wishes to invite interested laboratories to participate in this pilot comparison programme. This exercise is expected to be useful for all participants and will hopefully open the way for the establishment of routine comparisons in this area. The results will be discussed and published in an appropriate journal. Interested institutions should contact directly Mr. Paulo H. B. Becker through e-mail (pbecker at ird.gov.br) or fax +55 21 24421950 informing him of the model and manufacturer of the electrometer to be used for the pilot study and discuss all practical details.

    Unintentional falls from windows are an important cause of paediatric morbidity. There have been no controlled studies to identify modifiable environmental risk factors for window falls in young children. The authors have piloted a case-control study to test procedures for case identification, subject enrolment, and environmental data collection. Case windows were identified when a child 0-9 years old presented for care after a fall from that window. Control windows were identified (1) from the child's home and (2) from the home of an age- and gender-matched child seeking care for an injury diagnosis not related to a window fall. Study staff visited enrolled homes to collect window measurements and conduct window screen performance tests. The authors enrolled and collected data on 18 case windows, 18 in-home controls, and 14 matched community controls. Six potential community controls were contacted for every one enrolled. Families who completed the home visit viewed study procedures positively. Case windows were more likely than community controls to be horizontal sliders (100% vs 50%), to have deeper sills (6.28 vs 4.31 inches), to be higher above the exterior surface (183 vs 82 inches), and to have screens that failed below a threshold derived from the static pressure of a 3-year-old leaning against the mesh (60.0% vs 16.7%). Case windows varied very little from in-home controls. Case-control methodology can be used to study risk factors for paediatric falls from windows. Recruitment of community controls is challenging but essential, because in-home controls tend to be over-matched on important variables. A home visit allows direct measurement of window type, height, sill depth, and screen performance. These variables should all be investigated in subsequent, larger studies covering major housing markets.

    With the increasing prevalence of electronic readers (e-readers) for vocational and professional uses, it is important to discover if there are visual consequences in the use of these products. There are no studies in the literature quantifying the incidence or severity of eyestrain, nor are there clinical characteristics that may predispose to these symptoms with e-reader use. The primary objective of this pilot study was to assess the degree of eyestrain associated with e-reader use compared to traditional paper format. The secondary outcomes of this study were to assess the rate of eyestrain associated with e-reader use and identify any clinical characteristics that may be associated with the development of eyestrain. Forty-four students were randomly assigned to study (e-reader iPAD) and control (print) groups. Participant posture, luminosity of the room, and reading distance from reading device were measured during a 1-h session for both groups. At the end of the session, questionnaires were administered to determine symptoms. Significantly higher rates of eyestrain (p = 0.008) and irritation (p = 0.011) were found among the iPAD study group as compared to the print 'control' group. The study group was also 4.9 times more likely to report severe eyestrain (95 % CI [1.4, 16.9]). No clinical characteristics predisposing to eyestrain could be identified. These findings conclude that reading on e-readers may induce increased levels of irritation and eyestrain. Predisposing factors, etiology, and potential remedial interventions remain to be determined.

    Full Text Available Abstract Background The efficacy of non-pharmacological intervention approaches such as physical activity, strength, and cognitive training for improving brain health has not been established. Before definitive trials are mounted, important design questions on participation/adherence, training and interventions effects must be answered to more fully inform a full-scale trial. Methods SHARP-P was a single-blinded randomized controlled pilot trial of a 4-month physical activity training intervention (PA and/or cognitive training intervention (CT in a 2 × 2 factorial design with a health education control condition in 73 community-dwelling persons, aged 70-85 years, who were at risk for cognitive decline but did not have mild cognitive impairment. Results Intervention attendance rates were higher in the CT and PACT groups: CT: 96%, PA: 76%, PACT: 90% (p=0.004, the interventions produced marked changes in cognitive and physical performance measures (p≤0.05, and retention rates exceeded 90%. There were no statistically significant differences in 4-month changes in composite scores of cognitive, executive, and episodic memory function among arms. Four-month improvements in the composite measure increased with age among participants assigned to physical activity training but decreased with age for other participants (intervention*age interaction p = 0.01. Depending on the choice of outcome, two-armed full-scale trials may require fewer than 1,000 participants (continuous outcome or 2,000 participants (categorical outcome. Conclusions Good levels of participation, adherence, and retention appear to be achievable for participants through age 85 years. Care should be taken to ensure that an attention control condition does not attenuate intervention effects. Depending on the choice of outcome measures, the necessary sample sizes to conduct four-year trials appear to be feasible. Trial Registration Clinicaltrials.gov Identifier: NCT00688155

    Full Text Available Aim: The goal of the pilot study was to compare the quality of life of patients with multiple sclerosis in the Presov region with or without the support of a self-help group. Design: The character of this pilot study on patients with MS was related to the use of self-help groups and their impact on the assessment of the quality of life of the respondents, with the help of a questionnaire (WHOQOL-BREF. Methods: The research was carried out in the Prešov region with the help of the standardized WHOQOL-BREF questionnaire. Ninety-one patients with MS participated in the pilot study (46 respondents attended a self-help group and 35 did not. Results: The groups, when compared, aided by the statistically evaluated WHOQOL-BREF domains, were found to show significant differences in their evaluation of quality of life in three domains: domain one: physical health; domain two: surviving; domain three: social relations. Better scores were achieved in these domains by those who attended a group. In the physical sphere, we noticed significant differences in sleep quality, and sexual satisfaction (p < 0.001, while in social and economic areas, there were significant differences in satisfaction with personal relationships (p < 0.001, and economic circumstances (p < 0.01, self-contentment (p < 0.01, and coping with negative feelings (p < 0.05. Conclusion: Patients with multiple sclerosis can live normal lives provided they are supported by their families, friends, health care professionals, and self-help groups.

    Environmental auditing is an important tool to ensure consistent and effective cleaning. Our pilot study compared an alcohol-based fluorescent marking product and an adenosine-5'-triphosphate bioluminescence product for use in an environmental auditing program to determine which product was more practical and acceptable to users. Both products were tested on 15 preselected high touch objects in randomly selected patient rooms, following regular daily cleaning. A room was considered a "pass" if ≥80% of surfaces were adequately cleaned as defined by manufacturers' guidelines. A qualitative survey assessed user preference and operational considerations. Using fluorescent marking, 9 of 37 patient rooms evaluated (24%) were considered a "pass" after daily cleaning. Using adenosine-5'-triphosphate bioluminescence, 21 of 37 patient rooms passed (57%). There was great variability in results between different high touch objects. Eighty percent of users preferred the alcohol-based fluorescent marking product because it provided an effective visual aid to coach staff on proper cleaning techniques and allowed simple and consistent application. Environmental auditing using translucent, alcohol-based fluorescent marking best met the requirements of our organization. Our results reinforce the importance of involving a multidisciplinary team in evaluating and operationalizing an environmental auditing program.

    The introduction of microvascular free flaps has revolutionised modern reconstructive surgery. Unfortunately, access to training opportunities at standardised training courses is limited and expensive. We designed a pilot study on microvascular anastomoses with the aim of verifying if a short course, easily reproducible, could transmit microvascular skills to participants; if the chosen pre-test was predictive of final performance; and if age could influence the outcome. A total of 30 participants (10 students, 10 residents and 10 surgeons) without any previous microvascular experience were instructed and tested during a single 3 to 5 hour course. The two microanastomoses evaluated were the first ever performed by each participant. More than the half of the cohort was able to produce both patent microanastomoses in less than 2 hours; two-thirds of the attempted microanastomoses were patent. The pretest predicted decent scores from poor performances with a sensitivity of 61.5%, specificity of 100%, positive predictive value of 100% and negative predictive value of 40%. Students and residents obtained significantly higher scores than surgeons. Since our course model is short, cost-effective and highly reproducible, it could be introduced and implemented anywhere as an educational prospect for preselecting young residents showing talent and natural predisposition and having ambitions towards microvascular reconstructive surgery. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

  15. Sociomoral Reasoning in Adults with ADHD: A Pilot Study

    Kate E. Thomason

    2014-08-01

    Full Text Available Attention Deficit Hyperactivity Disorder (ADHD is frequently linked with antisocial behaviour, yet less is known about its relationship with sociomoral reasoning, and the possible mediating effect of intelligence. A pilot study was designed to investigate the relationship between antisocial personality traits, intelligence and sociomoral reasoning in adults with ADHD. Twenty two adults with ADHD and 21 healthy controls, matched for age, gender and IQ completed a battery of measures including the National Adult Reading Test, Gough Socialisation Scale and Sociomoral Reflection Measure-Short Form. There was no difference between the groups and levels of sociomoral reasoning, despite the ADHD group reporting greater antisocial personality traits. Sociomoral reasoning was positively correlated with intelligence. Results from a hierarchical multiple regressions indicated that both antisocial traits and IQ were significant predictors of sociomoral reasoning, with IQ proving the most powerful predictor. Whilst antisocial personality traits may explain some of the variance in levels of sociomoral reasoning, a diagnosis of ADHD does not appear to hinder the development of mature moral reasoning. Intellectual functioning appears to facilitate the development of sociomoral reasoning. A further analysis showed that both ADHD and low sociomoral reasoning were significant predictors of antisocial traits. The current findings have important treatment implications.

    2011-05-01

    Impaired postural control and a high incidence of falls are commonly observed following stroke. Compensatory stepping responses are critical to reactive balance control. We hypothesize that, following a stroke, individuals with unilateral limb dyscontrol will be faced with the unique challenge of controlling such rapid stepping reactions that may eventually be linked to the high rate of falling. The objectives of this exploratory pilot study were to investigate compensatory stepping in individuals poststroke with regard to: (1) choice of initial stepping limb (paretic or non-paretic); (2) step characteristics; and (3) differences in step characteristics when the initial step is taken with the paretic vs. the non-paretic limb. Four subjects following stroke (38-165 days post) and 11 healthy young adults were recruited. Anterior and posterior perturbations were delivered by using a weight drop system. Force plates recorded centre-of-pressure excursion prior to the onset of stepping and step timing. Of the four subjects, three only attempted to step with their non-paretic limb and one stepped with either limb. Time to foot-off was generally slow, whereas step onset time and swing time were comparable to healthy controls. Two of the four subjects executed multistep responses in every trial, and attempts to force stepping with the paretic limb were unsuccessful in three of the four subjects. Despite high clinical balance scores, these individuals with stroke demonstrated impaired compensatory stepping responses, suggesting that current clinical evaluations might not accurately reflect reactive balance control in this population.

    Full Text Available Introduction. Diabetic retinopathy (DR is a sight-threatening complication of diabetes. Telemedicine tools can prevent blindness. We aimed to investigate the patients’ satisfaction when using such tools (fundus camera examination and the effect of demographic and socioeconomic factors on participation in screening. Methods. Pilot study involving fundus camera screening and self-administered questionnaire on participants’ experience during fundus examination (comfort, reliability, and future interest in participation, as well as demographic and socioeconomic factors was performed on 89 patients with known diabetes in Csongrád County, a southeastern region of Hungary. Results. Thirty percent of the patients had never participated in any ophthalmological screening, while 25.7% had DR of some grade based upon a standard fundus camera examination and UK-based DR grading protocol (Spectra™ software. Large majority of the patients were satisfied with the screening and found it reliable and acceptable to undertake examination under pupil dilation; 67.3% were willing to undergo nonmydriatic fundus camera examination again. There was a statistically significant relationship between economic activity, education and marital status, and future interest in participation. Discussion. Participants found digital retinal screening to be reliable and satisfactory. Telemedicine can be a strong tool, supporting eye care professionals and allowing for faster and more comfortable DR screening.

    Full Text Available Aim and Method. To examine in obese people the potential effectiveness of a six-week, two times weekly aquajogging program on body composition, fitness, health-related quality of life, and exercise beliefs. Fifteen otherwise healthy obese persons participated in a pilot study. Results. Total fat mass and waist circumference decreased 1.4 kg (P=.03 and 3.1 cm (P=.005, respectively. The distance in the Six-Minute Walk Test increased 41 meters (P=.001. Three scales of the Impact of Weight on Quality of Life-Lite questionnaire improved: physical function (P=.008, self-esteem (P=.004, and public distress (P=.04. Increased perceived exercise benefits (P=.02 and decreased embarrassment (P=.03 were observed. Conclusions. Aquajogging was associated with reduced body fat and waist circumference and improved aerobic fitness and quality of life. These findings suggest the usefulness of conducting a randomized controlled trial with long-term outcome assessments.

  19. Microwave Imaging of Human Forearms: Pilot Study and Image Enhancement

    2013-01-01

    Full Text Available We present a pilot study using a microwave tomography system in which we image the forearms of 5 adult male and female volunteers between the ages of 30 and 48. Microwave scattering data were collected at 0.8 to 1.2 GHz with 24 transmitting and receiving antennas located in a matching fluid of deionized water and table salt. Inversion of the microwave data was performed with a balanced version of the multiplicative-regularized contrast source inversion algorithm formulated using the finite-element method (FEM-CSI. T1-weighted MRI images of each volunteer’s forearm were also collected in the same plane as the microwave scattering experiment. Initial “blind” imaging results from the utilized inversion algorithm show that the image quality is dependent on the thickness of the arm’s peripheral adipose tissue layer; thicker layers of adipose tissue lead to poorer overall image quality. Due to the exible nature of the FEM-CSI algorithm used, prior information can be readily incorporated into the microwave imaging inversion process. We show that by introducing prior information into the FEM-CSI algorithm the internal anatomical features of all the arms are resolved, significantly improving the images. The prior information was estimated manually from the blind inversions using an ad hoc procedure.

    Hospitalization, surgery and anaesthesia may lead to new-onset maladaptive behaviour, emotional distress and trauma. This pilot study aims to investigate the influence of intraoperatively applied music on post-operative behaviour in children and adolescents. Children with an ASA physical state classification of I or II, aged from 4 to 16 years and scheduled for elective circumcision or inguinal hernia repair under combined general and caudal anaesthesia were included. The children were randomized into two groups. They wore headphones during surgery, and were either exposed to music or not. All involved staff were blinded. Post-operative behaviour was documented by parents on day 7, 14 and 28 after surgery, using a questionnaire adapted from the "Post Hospitalization Behavioural Questionnaire" (PHBQ). Overall occurrence of at least one item indicating maladaptive behaviour was the primary outcome. Data are presented as median (interquartile range). In total, 135 children aged 6.6 (5.3-8.5) years, weighing 22 (19-29) kg, were included, with 112 completed questionnaires returned. Overall occurrence of at least one maladaptive item was lower in the music group, with a significantly lower incidence on day 7 (51% vs. 77% in controls; P music application in children undergoing minor surgical procedures may reduce the incidence of post-operative maladaptive behaviour within the first week. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

    Full Text Available Tsetse (Glossina sensu stricto are cyclical vectors of human and animal trypanosomoses, that are presently targeted by the Pan African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC coordinated by the African Union. In order to achieve effective control of tsetse, there is need to produce elaborate plans to guide intervention programmes. A model intended to aid in the planning of intervention programmes and assist a fuller understanding of tsetse distribution was applied, in a pilot study in the Masoka area, Mid-Zambezi valley in Zimbabwe, and targeting two savannah species, Glossina morsitans morsitans and Glossina pallidipes.The field study was conducted between March and December 2015 in 105 sites following a standardized grid sampling frame. Presence data were used to study habitat suitability of both species based on climatic and environmental data derived from MODIS and SPOT 5 satellite images. Factors influencing distribution were studied using an Ecological Niche Factor Analysis (ENFA whilst habitat suitability was predicted using a Maximum Entropy (MaxEnt model at a spatial resolution of 250 m. Area Under the Curve (AUC, an indicator of model performance, was 0.89 for G. m. morsitans and 0.96 for G. pallidipes. We then used the predicted suitable areas to calculate the probability that flies were really absent from the grid cells where they were not captured during the study based on a probability model using a risk threshold of 0.05. Apart from grid cells where G. m. morsitans and G. pallidipes were captured, there was a high probability of presence in an additional 128 km2 and 144 km2 respectively.The modelling process promised to be useful in optimizing the outputs of presence/absence surveys, allowing the definition of tsetse infested areas with improved accuracy. The methodology proposed here can be extended to all the tsetse infested parts of Zimbabwe and may also be useful for other PATTEC national initiatives in other

    Eosinophilic disorders of the gastrointestinal tract are an emerging subset of immune pathologies within the spectrum of allergic inflammation. Eosinophilic Esophagitis (EoE), once considered a rare disease, is increasing in incidence, with a rate of over 1 in 10,000 in the US, for unknown reasons. The clinical management of EoE is challenging, thus there is an urgent need for understanding the etiology and pathophysiology of this eosinophilic disease to develop better therapeutic approaches. In this open label, single arm, unblinded study, we evaluated the effects of an anti-IgE treatment, omalizumab, on local inflammation in the esophagus and clinical correlates in patients with EoE. Omalizumab was administered for 12 weeks to 15 subjects with long standing EoE. There were no serious side effects from the treatment. Esophageal tissue inflammation was assessed both before and after therapy. After 3 months on omalizumab, although tissue Immunoglobulin E (IgE) levels were significantly reduced in all but two of the subjects, we found that full remission of EoE, which is defined as histologic and clinical improvement only in 33% of the patients. The decrease in tryptase-positive cells and eosinophils correlated significantly with the clinical outcome as measured by improvement in endoscopy and symptom scores, respectively. Omalizumab-induced remission of EoE was limited to subjects with low peripheral blood absolute eosinophil counts. These findings demonstrate that in a subset of EoE patients, IgE plays a role in the pathophysiology of the disease and that anti-IgE therapy with omalizumab may result in disease remission. Since this study is open label there is the potential for bias, hence the need for a larger double blind placebo controlled study. The data presented in this pilot study provides a foundation for proper patient selection to maximize clinical efficacy. Trial Registration ClinicalTrials.gov NCT01040598 PMID:25789989

    Otolaryngology residents need concise, easily accessible modules to expand educational opportunities between surgical cases. These modules should be inexpensive to create and improve learning outcomes. The purpose of this pilot study was to assess whether otolaryngology residents at multiple institutions used online video modules to supplement their studying for the Otolaryngology Training Exam, whether the modules had any effect on their Otolaryngology Training Examination Scores, and to obtain survey feedback about the modules. This randomized trial was conducted in 3 academic departments of otolaryngology in the United States among 37 residents enrolled in 3 otolaryngology residency programs. Residents were randomized into 2 groups, one with access to the educational modules and the other with no access. Otolaryngology training examination scores were obtained from the year prior to the intervention (2012) and the year following module access (2013). Residents with access to the modules were also surveyed to assess use and obtain feedback about the modules. Otolaryngology training examination scores improved significantly from 2012 to 2013 among both residents who had access to the modules and those who did not in the sections of head and neck, laryngology, and sleep medicine. However, scores in the sections of pediatric otolaryngology (8% increase, P = .03), otology (7% increase, P = .02), and facial plastic surgery (10% increase, P = .02) improved from 2012 to 2013 only among residents with access to the modules. All respondents rated the videos as very helpful, with a rating of 4 of 5 on a Likert scale. Online otolaryngology educational modules are an inexpensive way to expand resident learning opportunities. Despite the lack of quantifiable improvement in otolaryngology training examination scores in this study, use of online modules sends a message to otolaryngology residents that their education is a priority; self-study outside the hospital

    Verneuil's disease is a chronic inflammatory skin disease of the follicles in apocrine glands rich area of the skin (axillary, inguinal, anogenital) and is associated with a deficient skin innate immunity. It is characterized by the occurrence of nodules, abscesses, fistulas, scars. Recently, vitamin D has been shown to stimulate skin innate immunity. The primary objective of the study was to assess whether Verneuil's disease was associated with vitamin D deficiency. The secondary objective was to determine whether vitamin D supplementation could improve inflammatory lesions. First, 25(OH) vitamin D3 serum levels in patients with Verneuil's disease followed at Nantes University Hospital were compared to those of healthy donors from the French Blood Bank. Then, a pilot study was conducted in 14 patients supplemented with vitamin D according to their vitamin D level at baseline at months 3 and 6. The endpoints at 6 months were decreased by at least 20% in the number of nodules and in the frequency of flare-ups. Twenty-two patients (100%) had vitamin D deficiency (level vitamin D deficiency (91%) of whom 14% were severely deficient. In 14 patients, the supplementation significantly decreased the number of nodules at 6 months (P = 0.01133), and the endpoints were achieved in 79% of these patients. A correlation between the therapeutic success and the importance of the increase in vitamin D level after supplementation was observed (P = 0.01099). Our study shows that Verneuil's disease is associated with a major vitamin D deficiency, correlated with the disease severity. It suggests that vitamin D could significantly improve the inflammatory nodules, probably by stimulating the skin innate immunity. A larger randomized study is needed to confirm these findings. © 2014 European Academy of Dermatology and Venereology.

    As a part of Fire PSA for KAPS, a pilot study has been taken up identifying CWPH as the important zone vulnerable to fire. As the CWPH houses pumps belonging to all important cooling (APWC, FFW, NAHPPW, NALPW, etc.) of both the units, a single fire leads to failure of multiple safety/safety support system cooling affecting the safety of the plant. The objective of this study is as follows: Familiarising with the various published Fire-PSA study, comparing and finalisation of the computer code amongst various codes available with DAE, identifying and sequencing different activities involved for carrying out Fire PSA, i.e. Zoning and Sub-Zoning of Fire Source Area, Fire vulnerability of System and Component surrounding Fire Source, etc., finalization of report format and documentation. Computer Code FDS is used to carry out Fire Hazard Analysis. FDS is the latest state-of the-art software package extensively used for Fire Hazard Analysis. It develops a 3D scenario for any given fire giving credit to actual physical location of fire load and ventilation. It gives the time dependent of any fire in a specific zone crediting the time required by operator to take necessary preventive action which helps in quantifying the probability of error for any particular operator's for PSA study. To identify the most vulnerable sub-zone in CWPH, a walk down was organized and physical location of each load; their separation, fire barrier, ventilator in the room, arrangement of fire protection/fighting system, localized operator's room were reviewed. Fire in the middle diesel tank with pump is considered as initiating event in the sub-zone of CWPH. The Event Tree for this initiating event for CWPH was developed. Event Tree end states are identified as large fire i.e. fire which is failed to be detected by both means, i.e. early and late and failure in fighting by both means i.e. early and late. (author)

  7. Cluster Sampling Bias in Government-Sponsored Evaluations: A Correlational Study of Employment and Welfare Pilots in England.

    For pilot or experimental employment programme results to apply beyond their test bed, researchers must select 'clusters' (i.e. the job centres delivering the new intervention) that are reasonably representative of the whole territory. More specifically, this requirement must account for conditions that could artificially inflate the effect of a programme, such as the fluidity of the local labour market or the performance of the local job centre. Failure to achieve representativeness results in Cluster Sampling Bias (CSB). This paper makes three contributions to the literature. Theoretically, it approaches the notion of CSB as a human behaviour. It offers a comprehensive theory, whereby researchers with limited resources and conflicting priorities tend to oversample 'effect-enhancing' clusters when piloting a new intervention. Methodologically, it advocates for a 'narrow and deep' scope, as opposed to the 'wide and shallow' scope, which has prevailed so far. The PILOT-2 dataset was developed to test this idea. Empirically, it provides evidence on the prevalence of CSB. In conditions similar to the PILOT-2 case study, investigators (1) do not sample clusters with a view to maximise generalisability; (2) do not oversample 'effect-enhancing' clusters; (3) consistently oversample some clusters, including those with higher-than-average client caseloads; and (4) report their sampling decisions in an inconsistent and generally poor manner. In conclusion, although CSB is prevalent, it is still unclear whether it is intentional and meant to mislead stakeholders about the expected effect of the intervention or due to higher-level constraints or other considerations.

    The silicon pixel detector is the innermost component of the CMS tracking system. It was replaced in March 2017 with an upgraded one, called the Phase 1 upgrade detector. During Long Shutdown 1, a third disk was inserted into the present forward pixel detector with eight prototype blades constructed using a new digital read-out chip architecture and a prototype readout chain. Testing the performance of these pilot modules enabled us to gain experience with the Phase 1 upgrade modules. In this document, the data reconstruction with the pilot system is presented. The hit finding efficiency and residual of these new modules is also shown, and how these observables were used to adjust the timing of the pilot blades.

    This paper discusses a case study that examined the influence of cultural, organizational and automation capability upon human trust in, and reliance on, automation. In particular, this paper focuses on the design and application of an extended case study methodology, and on the foundational lessons revealed by it. Experimental test pilots involved in the research and development of the US Air Force's newly developed Automatic Ground Collision Avoidance System served as the context for this examination. An eclectic, multi-pronged approach was designed to conduct this case study, and proved effective in addressing the challenges associated with the case's politically sensitive and military environment. Key results indicate that the system design was in alignment with pilot culture and organizational mission, indicating the potential for appropriate trust development in operational pilots. These include the low-vulnerability/ high risk nature of the pilot profession, automation transparency and suspicion, system reputation, and the setup of and communications among organizations involved in the system development.

    At present there is a lack of appropriate quality measures for benchmarking in general surgery units of Spanish National Health System. The aim of this study is to present the selection, development and pilot-testing of an initial set of surgical quality indicators for this purpose. A modified Delphi was performed with experts from the Spanish Surgeons Association in order to prioritize previously selected indicators. Then, a pilot study was carried out in a public hospital encompassing qualitative analysis of feasibility for prioritized indicators and an additional qualitative and quantitative three-rater reliability assessment for medical record-based indicators. Observed inter-rater agreement, prevalence adjusted and bias adjusted kappa and non-adjusted kappa were performed, using a systematic random sample (n=30) for each of these indicators. Twelve out of 13 proposed indicators were feasible: 5 medical record-based indicators and 7 indicators based on administrative databases. From medical record-based indicators, 3 were reliable (observed agreement >95%, adjusted kappa index >0.6 or non-adjusted kappa index >0.6 for composites and its components) and 2 needed further refinement. Currently, medical record-based indicators could be used for comparison purposes, whilst further research must be done for validation and risk-adjustment of outcome indicators from administrative databases. Compliance results in the adequacy of informed consent, diagnosis-to-treatment delay in colorectal cancer, and antibiotic prophylaxis show room for improvement in the pilot-tested hospital.

    Preventive interventions with parents of infants have tended to focus on mothers. Recent research focused on fathers suggests that their involvement in interventions might enhance effectiveness. One effective approach with mothers is the brief, home-based Video-feedback Intervention to promote Positive Parenting (VIPP). This paper is a report of a pilot study of VIPP with fathers to assess its feasibility. Five fathers were recruited from an existing longitudinal study of parents. The primary outcome was acceptability, assessed using a semi-structured questionnaire after completion of the intervention. All fathers completed all sessions of the intervention. Fathers rated the intervention as having had a significant impact on their understanding of their child’s thoughts and feelings, and as having improved their communication and relationship with their baby. Fathers’ feedback was generally positive. The flexibility to conduct sessions at home (or at fathers’ places of work) and the flexible timing of sessions were identified as fundamental to successful delivery. The results of this pilot study are encouraging, as VIPP with fathers was feasible. In light of the modest sample size, and the use of a non-clinical sample, the intervention must be evaluated with larger, clinical samples to evaluate its efficacy with fathers. PMID:22434935

    Full Text Available Objectives. Several groups in Manitoba, Canada, experience early childhood caries (ECC, including Aboriginal, immigrant, and refugee children and those from select rural regions. The purpose of this pilot study was to explore the views of parents and caregivers from four cultural groups on early childhood oral health and ECC. Methods. A qualitative descriptive study design using focus groups recruited parents and caregivers from four cultural groups. Discussions were documented, audio-recorded, transcribed, and then analyzed for content based on themes. Results. Parents and caregivers identified several potential barriers to good oral health practice, including child’s temperament, finances, and inability to control sugar intake. Both religion and genetics were found to influence perceptions of oral health. Misconceptions regarding breastfeeding and bottle use were present. One-on-one discussions, parental networks, and using laypeople from similar backgrounds were suggested methods to promote oral health. The immigrant and refugee participants placed emphasis on the use of visuals for those with language barriers while Hutterite participants suggested a health-education approach. Conclusions. These pilot study findings provide initial insight into the oral health-related knowledge and beliefs of these groups. This will help to inform planning of ECC prevention and research strategies, which can be tailored to specific populations.

    Clinical decision making requires 2 distinct cognitive skills: the ability to classify patients' conditions into diagnostic and management categories that permit the application of research evidence and the ability to individualize or-more specifically-to contextualize care for patients whose circumstances and needs require variation from the standard approach to care. The purpose of this study was to develop and test a methodology for measuring physicians' performance at contextualizing care and compare it to their performance at planning biomedically appropriate care. First, the authors drafted 3 cases, each with 4 variations, 3 of which are embedded with biomedical and/or contextual information that is essential to planning care. Once the cases were validated as instruments for assessing physician performance, 54 internal medicine residents were then presented with opportunities to make these preidentified biomedical or contextual errors, and data were collected on information elicitation and error making. The case validation process was successful in that, in the final iteration, the physicians who received the contextual variant of cases proposed an alternate plan of care to those who received the baseline variant 100% of the time. The subsequent piloting of these validated cases unmasked previously unmeasured differences in physician performance at contextualizing care. The findings, which reflect the performance characteristics of the study population, are presented. This pilot study demonstrates a methodology for measuring physician performance at contextualizing care and illustrates the contribution of such information to an overall assessment of physician practice.

    Full Text Available The main aim of the study is pilot evaluation of the life skills program REBOUND in a school context focusing on substance use, risk perception, and knowledge about psychoactive substances ( n IG + CG = 723 students in five schools and 46 classes, Mage = 14.8, range 14-18 for the total sample and in the subgroups gender, age, and school type. Main goal of the study is collecting evidence for program optimization. A controlled study was carried out with repeated measurement before and after the intervention (4-6 months. Multilevel analyses, ANCOVA, and logistic regression analyses were applied to measure the effects. Overall, significantly lower incidence rates of drunkenness (odds ratio [OR] = .55; p = .033, improved knowledge about psychoactive substances (p = .006, lower personal (p = .013 and general tobacco risk perception among users (p = .002, and lower general tobacco (p = .018 and cannabis (p = .000 risk perception in non-users were found in the total intervention group. In subgroups, significantly lower rates for the incidence of drunkenness can be shown for males (p = .008 and for younger participants (p = .004. Students at academic high school (German Gymnasium showed a decrease in 30-day prevalence for alcohol (p = .017 and cannabis (p = .014, and they improved in their knowledge about psychoactive substances (p = .000. In vocational high school classes (German Realschule, there was an increase in the relative alcohol risk perception of the students (p = .019. REBOUND contributes to a controlled use of alcohol and increases knowledge about psychoactive substances. REBOUND has various effects on the examined subgroups age, gender, and school type: Males, younger students, and students in academic high school benefitted more from the course regarding consumption-related criteria. We suggest a program optimization specific to school form and age, inclusion of a tobacco intervention, and the use of more gender-segregated interventions.

    Dietary sodium, protein, acid precursors, and water have been linked to cyst growth in polycystic kidney disease; yet, no studies in patients have examined the feasibility of using a dietary intervention that controls all of these factors. The aim of this study was to determine if a diet, appropriate for persons of most ages, reduces the excretion of sodium, urea, acid, and decreases mean urine osmolality while gaining acceptance by patients with autosomal dominant polycystic kidney disease (ADPKD). Twelve adults with ADPKD enrolled in a pre-post pilot feasibility study and served as their own controls. Individuals consumed their usual diet for one week then for four weeks followed an isocaloric diet lower in sodium and protein and higher in fruits, vegetables, and water. Three-day diet records and two 24-h urine samples were collected at baseline, week 2, and week 4 visits; blood pressure, weight, and serum were obtained at all three visits. A modified nutrition hassles questionnaire was completed on the last visit. During the dietary intervention, subjects (n = 11) consumed less sodium, protein, and dietary acid precursors 36%, 28%, and 99%, respectively, and increased fluid intake by 42%. Urinary sodium, urea, net acid excretion, osmoles, and osmolality decreased 20%, 28%, 20%, 37%, and 15%, respectively; volume increased 35%. Urine changes were in accord with the diet record. Ninety-one percent of participants reported that none of the hassles were worse than "somewhat severe", and most participants felt "somewhat confident" or "very confident" that they could manage the new diet. A majority of adult patients with ADPKD successfully prepared and followed a composite diet prescription with decreased sodium, protein, acid precursors, and increased fluid intake.

    Establish whether the Sbisa bar, Bagolini filter (BF) bar, and neutral density filter (NDF) bar, used to measure density of suppression, are equivalent and possess test-retest reliability. Determine whether density of suppression is altered when measurement equipment/testing conditions are changed. Our pilot study had 10 subjects aged ≥18 years with childhood-onset strabismus, no ocular pathologies, and no binocular vision when manifest. Density of suppression upon repeated testing, with clinic lights on/off, and using a full/reduced intensity light source, was investigated. Results were analysed for test-retest reliability, equivalence, and changes with alteration of testing conditions. Test-retest reliability issues were present for the BF bar (median 6 filter change from first to final test, p = 0.021) and NDF bar (median 5 filter change from first to final test, p = 0.002). Density of suppression was unaffected by environmental illumination or fixation light intensity variations. Density of suppression measurements were higher when measured with the NDF bar (e.g. NDF bar = 1.5, medium suppression, vs BF bar = 6.5, light suppression). Test-retest reliability issues may be present for the two filter bars currently still under manufacture. Changes in testing conditions do not significantly affect test results, provided the same filter bar is used consistently for testing. Further studies in children with strabismus having active amblyopia treatment would be of benefit. Despite extensive use of these tests in the UK, this is to our knowledge the first study evaluating filter bar equivalence/reliability.

    A growing older adult population is leading to increased admission rates to long-term care facilities such as nursing homes and residential care homes. Assisted healthcare services should be flexible, integrated, and responsive to older adults' needs. However, there is a limited body of empirical evidence because of the recruitment challenges in these settings. To describe the barriers and challenges faced in recruiting to a recent pilot study, consider previously implemented and proposed recruitment strategies, and propose a new multi-method approach to maximising recruitment of care homes. The proposed multi-method approach harnesses key recruitment strategies previously highlighted as effective in navigating the many challenges and barriers that are likely to be encountered, such as mistrust, scepticism and concerns about disruption to routines. This includes making strategic use of existing personal and professional connections within the research team, engaging with care homes that have previously engaged with the research process, forming relationships of trust, and employing a range of incentives. Implementing carefully planned recruitment strategies is likely to improve relationships between nursing homes and researchers. As a consequence, recruitment can be augmented which can enable the production of rigorous evidence required for achieving effective nursing practice and patient wellbeing. Boosting recruitment rates is crucial in helping to build new and less biased research evidence and for informing and underpinning all forms of evidence-based practice. The lessons learned from our pilot and the review of the literature highlight these issues and better enable investigators to access research settings that commonly possess many complex recruitment barriers and challenges.

    Abstract Background In 2004, a review of pilot studies published in seven major medical journals during 2000-01 recommended that the statistical analysis of such studies should be either mainly descriptive or focus on sample size estimation, while results from hypothesis testing must be interpreted with caution. We revisited these journals to see whether the subsequent recommendations have changed the practice of reporting pilot studies. We also conducted a survey to identify the methodologic...

    The purpose of this project was to study the feasibility of reusing major components of a software system that had been used to control the operations of a spacecraft launched in the 1980s. The study was done in the context of a ground data processing system that was to be rehosted from a large mainframe to an inexpensive workstation. The study concluded that a systematic approach using inexpensive tools could aid in the reengineering process by identifying a set of certified reusable components. The study also developed procedures for determining duplicate versions of software, which were created because of inadequate naming conventions. Such procedures reduced reengineering costs by approximately 19.4 percent.

    Ergonomic evaluation of visual demands becomes crucial for the operators/users when rapid decision making is needed under extreme time constraint like navigation task of jet aircraft. Research reported here comprises ergonomic evaluation of pilot's vision in a jet aircraft in virtual environment to demonstrate how vision analysis tools of digital human modeling software can be used effectively for such study. Three (03) dynamic digital pilot models, representative of smallest, average and largest Indian pilot population were generated from anthropometric database and interfaced with digital prototype of the cockpit in Jack software for analysis of vision within and outside the cockpit. Vision analysis tools like view cones, eye view windows, blind spot area, obscuration zone, reflection zone etc. were employed during evaluation of visual fields. Vision analysis tool was also used for studying kinematic changes of pilot's body joints during simulated gazing activity. From present study, it can be concluded that vision analysis tool of digital human modeling software was found very effective in evaluation of position and alignment of different displays and controls in the workstation based upon their priorities within the visual fields and anthropometry of the targeted users, long before the development of its physical prototype.

    Design, construction and operation of a pilot for processing uranium containing ores are important stages in the process of project development of uranium production from ores because uranium contained minerals and the composition of minerals are unstable factors. In this case, pilot needs to be a simulation of a plant in the future, but with upgrade equipment compared that at laboratory scale. Results of lab research were used to select the most appropriate process for ore processing and selection of equipment for each stages. In the circumstance when there has been a lack of experience in processing uranium ores in Vietnam, the design and construction of such a pilot with completed technological procedures are essential. The main purpose of this work is to verify results of lab researches and optimize operational parameters of the process. In addition, several purposes were also considered such as study on the effects of solution circulation/recycling and accumulation of impurities in a long run; obtain necessary and sufficient information for design, cost estimate for investment and operation. The pilot only can achieve the expected objectives when ore sources (including reserves and characteristics) are determined; a complete technological process for obtaining technical uranium (yellowcake) is designed; investment and operational capitals are estimated and these estimates show the costs and benefits of the process. In this article, the authors will focus on the presentation of research results, including data on ore, process technology, material balance, pilot scale, the basic parameters of equipment, installation diagram of equipment, construction, power and water needs identification, preliminary calculation of investment and operational costs.

    Studies have shown that research participants fail to appreciate the difference between research and medical care, labeling such phenomenon as a "therapeutic misconception" (TM). Since research activity involving human participants is increasing in the Middle East, qualitative research investigating aspects of TM is warranted. Our objective was to assess for the existence of therapeutic misconception amongst Egyptians. Study Tool: We developed a semi-structured interview guide to elicit the knowledge, attitudes, and perspectives of Egyptians regarding medical research. We recruited individuals from the outpatient settings (public and private) at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. We analyzed the content of the transcribed text to identify the presence of a TM, defined in one of two ways: TM1 = inaccurate beliefs about how individualized care can be compromised by the procedures in the research and TM2 = inaccurate appraisal of benefit obtained from the research study. Our findings showed that a majority of participants (11/15) expressed inaccurate beliefs regarding the degree with which individualized care will be maintained in the research setting (TM1) and a smaller number of participants (5/15) manifested an unreasonable belief in the likelihood of benefits to be obtained from a research study (TM2). A total of 12 of the 15 participants were judged to have expressed a TM on either one of these bases. The presence of TM is not uncommon amongst Egyptian individuals. We recommend further qualitative studies investigating aspects of TM involving a larger sample size distinguished by different types of illnesses and socio-economic variables, as well as those who have and have not participated in clinical research.

  5. Endometrial Histology of Depomedroxyprogesterone Acetate Users: A Pilot Study

    2006-01-01

    Full Text Available Objective. To obtain pilot data on the endometrial histology of Depomedroxyprogesterone acetate (Depo-Provera, DMPA users experiencing breakthrough bleeding (BTB versus users with amenorrhea. To compare the endometrial histology of patients who used DMPA continuously for 3–12 months versus those who used it for 13 months or more. Methods. Cross-sectional study. Endometrial biopsy was obtained from all consenting patients who used DMPA for at least 3 months. Patients were divided into those with BTB in the last 3 months versus those with amenorrhea for at least 3 months. Histology results and duration of therapy were compared. Results. The proportion of women with chronic endometritis, uterine polyps, atrophic, proliferative, or progesterone-dominant endometrium did not differ between those DMPA users with BTB versus those with amenorrhea. Duration of therapy did not correlate with symptoms of BTB or endometrial histology. Chronic endometritis was the most common histologic finding (10/40, 25% and occurred more often in women experiencing BTB (35% versus 15% (RR 1.62 CI 0.91–2.87. Moreover, 45% of women with BTB had received DMPA for more than 12 months. Conclusions. BTB was more common than previously reported in women using DMPA for more than 12 months. Chronic endometritis, which may indicate an underlying infectious or intracavitary anatomic etiology, has not been previously reported as a frequent finding in DMPA users, and may be related to ethnic or other sociodemographic characteristics of our patient population. Further study to elucidate the etiology of chronic endometritis in these patients is warranted.

    Based on the observation that the parasite Onchocerca volvulus selectively absorbs vitamin A from the host, and the known toxicity of vitamin A in higher concentration, it was hypothesized that dying microfilariae (mf) release their stores of vitamin A (retinoids) into the host circulation in toxic concentrations, inducing the signs and symptoms of onchocerciasis. We conducted a pilot study to test the hypothesis in Songea communities in Southern Tanzania, where mass drug administration with ivermectin had not been implemented by the time of the survey. The specific aim was to evaluate the correlation between the diagnosis of onchocerciasis and increased levels of retinoic acid at infection sites. The analysis was performed by determining copy numbers of a genome of O volvulus present in skin snip samples of persons with onchocerciacis, and correlating these numbers with expression levels of retinoic acid receptor-α (RAR-α), which is inducible by retinoic acid. Total DNA and RNA were extracted from each of 25 mf-positive and 25 mf-negative skin samples and evaluated using quantitative polymerase chain reaction with appropriate negative controls. Analysis of the samples, adjusted with glyceraldehyde 3-phosphate dehydrogenase gene levels, revealed that most samples with detectable RAR-α transcripts had higher levels of RAR-α expression than the assay control. However, the quality and number of samples were insufficient for statistical analysis. Fold data on the expression levels of both O volvulus DNA and RAR RNA suggested a possible trend toward higher relative RAR-α expression in samples with higher levels of O volvulus DNA ( r 2  = 0.25, P  = .079). Evidence of a contribution of vitamin A to the pathology of onchocerciasis thus remains elusive. Future studies on the role of retinoids in onchocerciasis will require larger groups of participants as well as careful monitoring of the cold chain and tissue storage procedures in view of the sensitivity of

Pediatricians often function as team leaders in the resuscitation of a critically ill child. However, pediatric residents often report having little opportunity to perform in the role of team leader during residency. In order to gain more insight into leadership skills and behaviors, we classified leadership styles of pediatric residents during simulated emergencies. Methods: We conducted a prospective quantitative study to investigate leadership styles used by pediatric residents during simulated emergencies with clinical deterioration of a child at a pediatric ward. Using videotaped scenarios of 48 simulated critical events among 12 residents, we were able to classify verbal and nonverbal communication into different leadership styles according to the situational leadership theory. Results: The coaching style (mean 54.5%, SD 7.8 is the most frequently applied by residents, followed by the directing style (mean 35.6%, SD 4.1. This pattern conforms to the task- and role-related requirements in our scenarios and it also conforms to the concept of situational leadership. We did not find any significant differences in leadership style according to the postgraduate year or scenario content. Conclusion: The model used in this pilot study helps us to gain a better understanding of the development of effective leadership behavior and supports the applicability of situational leadership theory in training leadership skills during residency.

    Full Text Available Abstract Objective Few methodological studies address the prioritization of clinical topics for the development of Clinical Practice Guidelines (CPGs. The aim of this study was to validate a methodology for Priority Determination of Topics (PDT of CPGs. Methods and results Firstly, we developed an instrument for PDT with 41 criteria that were grouped under 10 domains, based on a comprehensive systematic search. Secondly, we performed a survey of stakeholders involved in CPGs development, and end users of guidelines, using the instrument. Thirdly, a pilot testing of the PDT procedure was performed in order to choose 10 guideline topics among 34 proposed projects; using a multi-criteria analysis approach, we validated a mechanism that followed five stages: determination of the composition of groups, item/domain scoring, weights determination, quality of the information used to support judgments, and finally, topic selection. Participants first scored the importance of each domain, after which four different weighting procedures were calculated (including the survey results. The process of weighting was determined by correlating the data between them. We also reported the quality of evidence used for PDT. Finally, we provided a qualitative analysis of the process. The main domains used to support judgement, having higher quality scores and weightings, were feasibility, disease burden, implementation and information needs. Other important domains such as user preferences, adverse events, potential for health promotion, social effects, and economic impact had lower relevance for clinicians. Criteria for prioritization were mainly judged through professional experience, while good quality information was only used in 15% of cases. Conclusion The main advantages of the proposed methodology are supported by the use of a systematic approach to identify, score and weight guideline topics selection, limiting or exposing the influence of personal biases

    Full Text Available Background: One of the most important factors affecting success rates in assisted reproductive techniques (ART besides the number of oocytes retrieved and high quality embryos derived from them is the technical aspects of embryo transfer. It seems that pretreatement with uterine relaxants can be helpful in preventing unpleasant cramps which can have an adverse effect on ART outcome. In this respect, some drugs such as prostaglandin inhibitors or sedatives have been evaluated but not confirmed yet remain controversial. This study was performed in order to assess the effect of administrating Piroxicam prior to embryo transfer on pregnancy rates in ART cycles. Materials and Methods: This pilot study was performed from August 2010 through December 2011 on 50 infertile women in ART cycles. Recombinant follicle stimulating hormone (rFSH with a long gonadotropin releasing hormone (GnRH analogue protocol were used for controlled ovarian hyperstimulation. The subjects were randomly allocated into two groups of 25 patients after obtaining written consent. Group A received a 10 mg Piroxicam capsule 30 minutes before embryo transfer and group B was the control group with no treatment. Data were analyzed by Chi-square and analysis of variance (ANOVA. Results: Pregnancy rate was 34% (n=17 totally, with 32% (n=8 in group A and 36% (n=9 in group B (p=0.75. Uterine cramps were experienced by 4 women (16% in group B, while none were reported by women in group A (p=0.037. Conclusion: It seems that Piroxicam administration 30 minutes prior to embryo transfer cannot increase pregnancy rates, but can prevent or reduce uterine cramps after the procedure.

    Full Text Available Abstract Background Demographic ageing will lead to increasing pressure on visual rehabilitation services, which need to be efficiently organised in the near future. The Dutch ICF Activity Inventory (D-AI was developed to assess the rehabilitation needs of visually impaired persons. This pilot study tests the feasibility of the D-AI using a computer-assisted telephone interview. Methods In addition to the regular intake, the first version of the D-AI was assessed in 20 patients. Subsequently, patients and intake assessors were asked to fill in an evaluation form. Based on these evaluations, a new version of the D-AI was developed. Results Mean administration time of the D-AI was 88.8 (± 41.0 minutes. Overall, patients and assessors were positive about the D-AI assessment. However, professionals and 60% of the patients found the administration time to be too long. All included items were considered relevant and only minor adjustments were recommended. Conclusion The systematic character of the revised D-AI will prevent topics from being overlooked and indicate which needs have the highest priority from a patient-centred perspective. Moreover, ongoing assessment of the D-AI will enhance evaluation of the rehabilitation process. To decrease administration time, in the revised D-AI only the top priority goals will be fully assessed. Using the D-AI, a rehabilitation plan based on individual needs can be developed for each patient. Moreover, it enables better evaluation of the effects of rehabilitation. A larger validation study is planned.

    The aim of the present study was to describe handwriting difficulties of primary school children with juvenile idiopathic arthritis (JIA), and to investigate possible correlations with hand function and writing performance. In a cross-sectional approach, 15 children with JIA and reported handwriting difficulties were included together with 15 healthy matched controls. Impairments (signs of arthritis or tenosynovitis, reduced grip force and limited range of motion of the wrist (wrist-ROM)), activity limitations (reduced quality and speed of handwriting, pain during handwriting), and participation restrictions (perceived handwriting difficulties at school) were assessed and analysed. Although selected by the presence of handwriting difficulties, the majority of the JIA children (73%) had no active arthritis of the writing hand, and only minor hand impairments were found. Overall, the JIA children performed well during the short handwriting test, but the number of letters they wrote per minute decreased significantly during the 5-minute test, compared to the healthy controls. JIA patients had significantly higher pain scores on a 100 mm Visual Analogue Scale, compared to the healthy controls. The actual presence of arthritis, and limitation in grip force and wrist-ROM did not correlate with reported participation restrictions with regard to handwriting at school. The JIA children reported pain during handwriting, and inability to sustain handwriting for a longer period of time. The results of this pilot study show that JIA children with handwriting difficulties, experience their restrictions mainly through pain and the inability to sustain handwriting for a longer period of time. No correlations could be found with impairments.

    Few studies have reported on interventions to alleviate financial toxicity in patients with cancer. We developed a financial navigation program in collaboration with our partners, Consumer Education and Training Services (CENTS) and Patient Advocate Foundation (PAF), to improve patient knowledge about treatment costs, provide financial counseling, and to help manage out-of-pocket expenses. We conducted a pilot study to assess the feasibility and impact of this program. Patients with cancer received a financial education course followed by monthly contact with a CENTS financial counselor and a PAF case manager for 6 months. We measured program adherence, self-reported financial burden and anxiety, program satisfaction, and type of assistance provided. Thirty-four patients (median age, 60.5 years) were consented (85% white and 50% commercially insured). Debt, income declines, and loans were reported by 55%, 55%, and 30% of patients, respectively. CENTS counselors assisted most often with budgeting, retirement planning, and medical bill questions. PAF case managers assisted with applications for appropriate insurance coverage, cost of living issues (eg, housing, transportation), and disability applications. High financial burden and anxiety about costs (4 or 5 on a Likert scale) were reported at baseline by 37% and 47% of patients, respectively. Anxiety about costs decreased over time in 33% of patients, whereas self-reported financial burden did not substantially change. Implementing an oncology financial navigation program is feasible, provides concrete assistance in navigating the cost of care, and mitigates anxiety about costs in a subset of patients. Future work will focus on measuring the program's impact on financial and clinical outcomes.

    Recovery of impaired motor functions following stroke is commonly incomplete in spite of intensive rehabilitation programmes. At 6 months following a stroke up to 60 % of affected individuals still suffer from permanent motor deficits, in particular hemiparetic gait, that are relevant for daily life. Novel innovative therapeutic strategies are needed to enhance the recovery of impaired gait function following stroke. This pilot study has investigated the effectiveness of conventional physiotherapy in comparison to an apparative cyclic movement training over a period of 4 weeks to improve (i) power during a submaximal cyclic movement training of the lower limbs, (ii) cardiac fitness, (iii) balance and gait ability, and (iv) quality of life in stroke patients. In comparison to physiotherapy apparative cyclic movement training improved power, balance, cardiac fitness and quality of life to a greater extent. However, there was a statistically significant difference between both intervention groups only for balance but not for the other parameters assessed. The present pilot study should inspire future research with larger patient cohorts to allow appropriate judgement on the effectiveness of apparative cyclic movement training in stroke rehabilitation. © Georg Thieme Verlag KG Stuttgart · New York.

    Subjective cognitive decline (SCD) may indicate unhealthy cognitive changes, but no standardized SCD measurement exists. This pilot study aims to identify reliable SCD questions. 112 cognitively normal (NC, 76±8 years, 63% female), 43 mild cognitive impairment (MCI; 77±7 years, 51% female), and 33 diagnostically ambiguous participants (79±9 years, 58% female) were recruited from a research registry and completed 57 self-report SCD questions. Psychometric methods were used for item-reduction. Factor analytic models assessed unidimensionality of the latent trait (SCD); 19 items were removed with extreme response distribution or trait-fit. Item response theory (IRT) provided information about question utility; 17 items with low information were dropped. Post-hoc simulation using computerized adaptive test (CAT) modeling selected the most commonly used items (n=9 of 21 items) that represented the latent trait well (r=0.94) and differentiated NC from MCI participants (F(1,146)=8.9, p=0.003). Item response theory and computerized adaptive test modeling identified nine reliable SCD items. This pilot study is a first step toward refining SCD assessment in older adults. Replication of these findings and validation with Alzheimer's disease biomarkers will be an important next step for the creation of a SCD screener.

    Numerous breast cancer patients experience cognitive changes during and after chemotherapy. Chemotherapy-related cognitive impairment can significantly affect quality of life. This pilot study attempted to determine the effects of a compensatory cognitive training on the objective and subjective cognitive functioning of breast cancer patients receiving adjuvant chemotherapy. Fifty-four patients were assigned to either a compensatory cognitive training or waitlist condition. They were assessed at baseline (T1), the completion of the 12-week intervention (T2), and 6 months after intervention completion (T3). Outcomes were assessed using the standardized neuropsychological tests and the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), version 3. Raw data were converted to T-scores based on baseline scores, and a repeated-measures ANCOVA, adjusting for age, intelligence, depression, and treatment, was used for analysis. The effect sizes for differences in means were calculated. The intervention group improved significantly over time compared to the waitlist group on objective cognitive function. Among ten individual neuropsychological measures, immediate memory, delayed memory, verbal fluency in category, and verbal fluency in letter showed significant group × time interaction. In subjective cognitive function, scores of the waitlist group significantly decrease over time on perceived cognitive impairments, in contrast to those of the intervention group. The 12-week compensatory cognitive training significantly improved the objective and subjective cognitive functioning of breast cancer patients. Because this was a pilot study, further research using a larger sample and longer follow-up durations is necessary.

    The use of new technologies in rehabilitation, such as virtual reality and/or computerized gaming exercises, may be useful to enable patients to practice intensively in a motivating way. The objective of the present randomized controlled pilot study was to compare the effect of reach training using a target group specific-designed rehabilitation game to time-matched standardized conventional reach training on arm function after stroke. Twenty chronic stroke patients were randomized to either the rehabilitation game group or the conventional training group. Both groups received three arm training sessions of 30 minutes each week, during a period of 6 weeks. Arm (the upper extremity part of Fugl-Meyer [FM] assessment) and hand (the Action Research Arm [ARA] test) functions were tested 1 week before (T0) and 1 week after (T1) training. A follow-up measurement was performed at 1 month after T1 (T2). ARA and FM scores improved significantly within both groups. Post hoc comparisons revealed significant increases in test scores between T0 and T1 and between T0 and T2 for both ARA and FM, but not for changes from T1 to T2. There were no significant differences between both groups for either clinical test. The present randomized controlled pilot study showed that both arm and hand function improved as much after training with a rehabilitation game as after time-matched conventional training.

    This study describes the development and pilot test of Asian Women's Action for Resilience and Empowerment (AWARE), a culturally informed group psychotherapy intervention designed to reduce depressive symptoms, suicidality, substance use, and HIV and sexual risk behaviors among 1.5 and second generation Asian American (AA) women. To participate, AA women had to meet the criteria for posttraumatic stress disorder (PTSD) or have a history of exposure to interpersonal violence (IPV) as determined using the Clinician-Administered PTSD Scale (CAPS) and Traumatic Life Events Questionnaire (TLEQ). This article also presents the preliminary feasibility and acceptability of AWARE from its Stage I pilot study of nine Chinese, Korean, and Vietnamese American women. To foster holistic treatment, AWARE was developed based on original research findings from Stage 0 and integrated theoretical models including fractured identity theory, empowerment theory, cognitive behavioral therapy (CBT), mindfulness-based techniques, and the AIDS Risk Reduction Model (ARRM). The development of AWARE was an iterative process informed by participant feedback, which led to frequent intervention modifications for a future randomized controlled trial (RCT) in Stage II. A qualitative analysis of participant feedback informed the following modifications: further exploration of feelings, improvements in technology delivery, learning and practicing coping skills, more specific cultural tailoring related to sexual health, decreased number of sessions and increased time per session. Findings provide support for the acceptability and feasibility of AWARE as "culturally informed" for AA young women with IPV histories, high-risk behaviors, and mental health issues.

    This paper describes a 4-month pilot study that tested the suitability of a physical activity intervention for first graders (children aged 6 and 7 years) in a public school in Santiago, Chile. Teachers were trained to deliver the programme in the classroom during the school day. Teachers were surveyed to determine if this intervention fit within their curriculum and classroom routines and they reported in a focus group that it was suitable for them. All children actively participated in the programme and positive changes in their attitudes towards physical activity were observed by their teachers. Anthropometrics, blood pressure and hand grip strength were measured in the students. A significant reduction was observed in children with high waist circumference ≥ 90th percentile, and in mean systolic blood pressure. However, statistical power values for those comparisons were rather low. Anthropometry and hand grip strength were not modified. The latter calculations and the lack of a control group are showing the weaknesses of this pilot study and that further research with a larger sample size and an experimental design is strongly needed.

    The Solar Detoxification Field Experiment was designed to investigate the photocatalytic decomposition of organic contaminants in groundwater at a Superfund site at Lawrence Livermore National Laboratory (LLNL). The process uses ultraviolet (UV) energy, available in sunlight, in conjunction with the photocatalyst, titanium dioxide, to decompose organic chemicals into nontoxic compounds. The field experiment was developed by three federal laboratories: the National Renewable Energy Laboratory (NREL), Sandia National Laboratory (SNLA), and LLNL. The US Department of Energy funded the experiment. The objectives of the pilot-scale study included the advancement of the solar technology into a nonlaboratory waste-remediation environment the compilation of test data to help guide laboratory research and future demonstrations and the development of safe operational procedures. Results of the pilot study are discussed, emphasizing the effect of several process variables on the system performance. These variables include alkalinity, catalyst loading, flow velocity through the reactor, and incident solar UV radiation. The performance of the solar detoxification process are discussed as it relates to concentrating and nonconcentrating collectors

    The authors present a pilot statistical study of murder-suicide comprising 32 cases from the years 1990-1992, collected from the offices of the medical examiners of seven counties in five of the United States. The study includes brief reviews of previous statistical surveys of murder, murder-suicide, and suicide. This present study's conclusions parallel the findings of previous research on the demographic characteristics of the perpetrators of murder-suicide, the relationship between killers and victims, the types of weapon used, locations of the incidents, and the time intervals between the murder and suicide. It also highlights the similarities between the characteristics of the perpetrator of murder-suicide and those of persons who commit only suicide, supporting the thesis that murder-suicide is an extended suicide. Suggestions for prevention of such a type of crime are offered.

    Randomized controlled trials (RCTs) involving surgical procedures are challenging for recruitment and infrequent in the specialty of bariatrics. The pilot phase of the By-Band-Sleeve study (gastric bypass versus gastric band versus sleeve gastrectomy) provided the opportunity for an investigation of recruitment using a qualitative research integrated in trials (QuinteT) recruitment intervention (QRI). The QRI investigated recruitment in two centers in the pilot phase comparing bypass and banding, through the analysis of 12 in-depth staff interviews, 84 audio recordings of patient consultations, 19 non-participant observations of consultations and patient screening data. QRI findings were developed into a plan of action and fed back to centers to improve information provision and recruitment organization. Recruitment proved to be extremely difficult with only two patients recruited during the first 2 months. The pivotal issue in Center A was that an effective and established clinical service could not easily adapt to the needs of the RCT. There was little scope to present RCT details or ensure efficient eligibility assessment, and recruiters struggled to convey equipoise. Following presentation of QRI findings, recruitment in Center A increased from 9% in the first 2 months (2/22) to 40% (26/65) in the 4 months thereafter. Center B, commencing recruitment 3 months after Center A, learnt from the emerging issues in Center A and set up a special clinic for trial recruitment. The trial successfully completed pilot recruitment and progressed to the main phase across 11 centers. The QRI identified key issues that enabled the integration of the trial into the clinical setting. This contributed to successful recruitment in the By-Band-Sleeve trial-currently the largest in bariatric practice-and offers opportunities to optimize recruitment in other trials in bariatrics.

    Many accidents at construction sites are due to falls. An exercise-based workplace intervention may improve intrinsic fall risk factors. In this pilot study, we aimed at evaluating the effects of neuromuscular exercise on static and functional balance performance as well as on lower limb explosive power in construction workers. Healthy middle-aged construction workers were non-randomly assigned to an intervention [N = 20, age = 40.3 (SD 8.3) years] or a control group [N = 20, age = 41.8 (9.9) years]. The intervention group performed static and dynamic balance and strength exercises (13 weeks, 15 min each day). Before and after the intervention and after an 8-week follow-up, unilateral postural sway, backward balancing (on 3- and 4.5-cm-wide beams) as well as vertical jump height were assessed. We observed a group × time interaction for postural sway (p = 0.002) with a reduction in the intervention group and no relevant change in the control group. Similarly, the number of successful steps while walking backwards on the 3-cm beam increased only in the intervention group (p = 0.047). These effects were likely to most likely practically beneficial from pretest to posttest and to follow-up test for postural sway (+12%, standardized mean difference (SMD) = 0.65 and 17%, SMD = 0.92) and backward balancing on the 3-cm beam (+58%, SMD = 0.59 and 37%, SMD = 0.40). Fifteen minutes of neuromuscular training each day can improve balance performance in construction workers and, thus, may contribute to a decreased fall risk.

  12. Environmental accounts and trade - a Swedish pilot study

    International Nuclear Information System (INIS)

    Wadeskog, A.

    2001-01-01

    Environmental accounts are supposed to register environmental impacts of economic activities performed by residents on a national basis. However, the international division of labour is not explicitly addressed. A small, open, economy like Sweden use resources, and thereby cause emissions, in other countries due to what is imported for intermediate or final use. On the other hand, the things we export to other countries cause emissions in Sweden. This means that there is an environmental balance of trade that is not explicitly addressed in the accounts. There are however possibilities to estimate these effects. Through input-output analysis it is possible to analyse the value added chain of the different goods and service that make up the final demand, i.e. a form of cradle-to-grave analysis. Environmental trade can be estimated in several ways. One method is to assume that emissions follow the pattern of the trade balance and equal out over time, i.e. ignore the problem. Another method is to calculate the effect of differences in volume and composition in exports and imports. In most cases this is done using the domestic input-output tables and emission coefficients, i.e. assuming that all trading partners have identical resource use, technology and economic structure. A pilot study of the environmental trade balance for Sweden, using different aggregated emissions data for our trading partners and the Swedish input-output table, show that the results calculated with these methods will underestimate external emissions considerably for carbon dioxides and sulphur dioxides. However, for nitrogen oxides emission these methods seem to suffice

    Current health care costs are unsustainable, with a large percentage of waste attributed to doctor practices. Medical educators are developing curricula to address value-based care (VBC) in education. There is, however, a paucity of curricula and assessments addressing levels higher than 'knows' at the base of Miller's pyramid of assessment. Our objective was to: (1) teach residents the principles of VBC using active learning strategies; and (2) develop and pilot a tool to assess residents' ability to apply principles of VBC at the higher level of 'knows how' on Miller's pyramid. Residents in medicine, medicine-paediatrics and medicine-dermatology participated in a 5-week VBC morning report curriculum using active learning techniques. Early sessions targeted knowledge and later sessions emphasised the application of VBC principles. Medical educators are developing curricula to address value-based care in education RESULTS: Thirty residents attended at least one session and completed both pre- and post-intervention tests, using a newly developed case-based assessment tool featuring a 'waste score' balanced with 'standard of care'. Residents, on average, reduced their waste score from pre-intervention to post-intervention [mean 8.8 (SD 6.3) versus mean 4.7 (SD 4.6), p = 0.001]. For those who reduced their waste score, most maintained or improved their standard of care. Our results suggest that residents may be able to decrease health care waste, with the majority maintaining or improving their management of care in a case-based assessment after participation in the curriculum. We are working to further incorporate VBC principles into more morning reports, and to develop further interventions and assessments to evaluate our residents at higher levels on Miller's pyramid of assessment. © 2018 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

  14. Development of a Falls Registry: A Pilot Study.

    Berg, Gina M; Carlson, Tara; Fairchild, Joanne; Edwards, Courtney; Sorell, Ryan

    Each year approximately 1 in 4 healthy older adults aged 65+ years and 1 in 2 aged 80+ years living in the community will fall. Fall-related injuries are the leading cause of death and disability and cost the United States approximately $31 billion annually. Currently, no repository of scene data exists that informs prevention programs regarding circumstances that contribute to older adult falls. This was a multicenter (4 sites: Kansas, Maryland, Oregon, and Texas) pilot study consisting of interviews of older (55+ years) patients who had been admitted to a trauma center with fall-related injuries. Questions included information regarding environment, behaviors, injuries, and demographics. Additional information was abstracted from patient medical record: comorbidities, medications, and discharge information. Data are presented descriptively. Forty-nine patients were interviewed: average age was 78 years; White (93.9%); female (53.1%); and most (63.3%) had fallen before. The most commonly reported fall factors and injuries included those occurring at home without agency services (65.0%), on hard flooring (51.1%), with laced shoes (44.2%), and with walkers (36.7%) and contained contusion/open wound of head (61.2%). Survey time was anecdotally estimated at 10-15 min. Preliminary data suggest that prevention efforts should emphasize on educating older adults to focus on ambulation, body position, and use of assistive devices in their daily activities. The development of a systematic and organized registry that documents scene data would inform public health agencies to develop fall prevention programs that promote older adult safety. Furthermore, it would provide a large sample size to test factor associations with injury severity.

  15. A Pilot Study Examining ADHD and Behavioural Disturbance in Female Mentally Disordered Offenders

    Full Text Available Compared with general population rates, prevalence rates of ADHD have been consistently reported to be higher in both male and female offender populations, the latter estimated to range between 10–29%. Research in forensic institutional settings has reported that aggressive behaviour is a particularly prominent source of impairment among men with ADHD. However there is a paucity of research investigating the type of behavioural incidents that may arise in female offenders with ADHD. This pilot study therefore aimed to further our understanding of ADHD within a cohort of female mentally disordered offenders by ascertaining estimated rates of ADHD and associated functional disturbance presenting in this population. Fifty female offenders completed the Barkley ADHD rating scales. Data on aggressive and self-harming behaviours were obtained from patients’ clinical records. Almost one-third of patients (28% screened positive for ADHD, most commonly hyperactive/impulsive and combined subtypes. They were significantly younger than their peers and there were no significant differences in behavioural disturbance records between groups. When controlling for age, hyperactive/impulsive symptoms and combined symptoms were significantly and positively correlated with measures of behavioural disturbance. ADHD symptoms correlated more strongly with self-harm than outward aggression, which is a novel finding. This pilot study has contributed to the knowledge base about the rate and functional problems of female offenders with ADHD. Future research should replicate the study using a larger sample and explore the effect of treatment (pharmacological and psychological on the reduction of ADHD symptoms, behavioural disturbance, length of stay and quality of life.

    There is a high prevalence of neck pain in air force pilots; however, the causes are not clear and are considered work-related. Kyphotic changes in the cervical spine have been known to cause neck pain. In this study, we investigated the association between neck pain and cervical kyphosis in air force pilots. This is a cross-sectional study of 63 Republic of South Korea Air Force pilots. We examined the C2-7 absolute rotation angle (ARA) using the posterior tangent method and other radiologic parameters on whole spine lateral radiographs. We divided the participants into a neck pain group (N = 32) and no neck pain group (N = 31), and subsequently analyzed the difference in radiographic parameters and clinical data between the two groups. There were no significant differences found in age, body mass index, total flight time, or aerobic or anaerobic exercise between the neck pain and control groups. The fighter pilots had higher 1-yr prevalence of neck pain than nonfighter pilots (84.4% vs. 15.6%). The lower C2-7 ARA (OR = 0.91, 95% CI 0.846, 0.979) and fighter type aircrafts (OR = 3.93, 95% CI 1.104, 13.989) were associated with neck pain. Fighter pilots experienced neck pain more frequently than the nonfighter pilots. Those fighter pilots suffering from neck pain were shown to have more kyphotic changes in the cervical spine than control pilots through evaluation of whole spine lateral radiographs using the posterior tangent method. These key findings suggest that the forces involved in flying a fighter type aircraft may affect cervical alignment and neck pain.

    This observational pilot study investigated effects of aromatherapy massage in paediatric burn patients. The setting was a 17 beds level I burn unit in Cape Town, South Africa. Between January and October 2009 heart rates and respiratory rates of patients who underwent aromatherapy massage sessions were read before and after the sessions. Primary outcomes were decline in heart rates and respiratory rates, a sign of relaxation. Behavioural responses (sleep/awake state, facial expression, body posture) were documented as secondary outcomes. A convenience sample of 71 paediatric burn patients (median age 3 years) underwent a total of 126 massage sessions. Mean heart rate decreased significantly from 118 (SD 20) to 109 (SD 21), t=9.8, pAromatherapy massage seems to be a helpful nonpharmacological approach to reduce hospitalized paediatric burn patients' distress. Future studies with better research designs and validated outcome measures should confirm our findings. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available The financial counseling, financial planning, and financial therapy fields are hampered by a conceptual and empirical paucity of clinical and experimental evidence-based research. In an attempt to decrease this gap in the literature, a pilot study was developed to test the implementation of a solution-focused financial therapy client intervention approach, in which solution-focused therapy techniques were applied in a financial counseling setting. This paper reports findings from a clinical intervention study of college students (N = 8 who presented a variety of financial issues related to budgeting, investing, and debt repayment problems. Data were gathered prior to the start of treatment, after treatment ended, and three months later. Participants’ psychological well-being and financial behaviors improved, while financial distress decreased. The solution-focused financial therapy approach used is discussed.

    This article presents a systematic review of the literature pertaining to the use of yoga in stroke rehabilitation. In addition, we present the results of a small pilot study designed to explore the hypothesis that a Kundalini yoga practice of 12 weeks would lead to an improvement in aphasia as well as in fine motor coordination in stroke patients. The 3 participants attended yoga classes twice a week for 12 weeks, before and after which they were tested on the O'Connor Tweezer Dexterity test, a timed test where the participant places pins in a Peg-Board with tweezers, and the Boston Aphasia Exam for speech. All 3 participants showed improvement on both measures. The small sample size makes it impossible to draw definite conclusions, but the positive trends in this study suggest that further research should be done to examine the effects of Kundalini yoga on specific illnesses or medical conditions.

    2005-11-01

    Previous studies have found a relation between weight loss and pain severity in various chronic pain populations. However, there has been little research examining the relation between body mass index (BMI) and fibromyalgia syndrome (FMS). The purpose of this pilot study was to investigate the relationship between BMI and FMS symptoms and to determine if FMS symptoms would decrease following weight loss. Overweight and obese women participated in a 20-week behavioral weight loss treatment. Participants, on average, lost 9.2 lbs (4.4% of their initial weight), and there were significant pre-postimprovements on several outcome measures. Although weight was not significantly related to pain at baseline, weight loss significantly predicted a reduction in FMS, pain interference, body satisfaction, and quality of life (QOL). Findings suggest that behavioral weight loss treatment could be included in the treatment for overweight/obese women with FMS.

    Although awareness of the importance of the research capacity of community-based organizations (CBOs) is growing, a uniform framework of the research capacity domains within CBOs has not yet been developed. To develop a framework and instrument (the Community REsearch Activity assessment Tool [CREAT]) for assessing the research activity and capacity of CBOs that incorporates awareness of the different data collection and analysis priorities of CBOs. We conducted a review of existing tools for assessing research capacity to identify key capacity domains. Instrument items were developed through an iterative process with CBO representatives and community researchers. The CREAT was then pilot tested with 30 CBOs. The four primary domains of the CREAT framework include 1) organizational support for research, 2) generalizable experiences, 3) research specific experiences, and 4) funding. Organizations reported a high prevalence of activities in the research-specific experiences domain, including conducting literature reviews (70%), use of research terminology (83%), and primary data collection (100%). Respondents see research findings as important to improve program and service delivery, and to seek funds for new programs and services. Funders, board members, and policymakers are the most important dissemination audiences. The work reported herein advances the field of CBO research capacity by developing a systematic framework for assessing research activity and capacity relevant to the work of CBOs, and by developing and piloting an instrument to assess activity in these domains.

    students taking part in this teaching unit found that this exercise represents a significant improvement of clinical teaching and recommended to introduce this teaching unit as a standard on the normal wards. Students teaching patients (SteP) appears to be an easy and cost-efficient tool to improve patients' education and students' learning. Students become aware of how difficult it is to explain surgical procedures and complications to patients and patients are better informed about their treatment. We plan to (i) introduce the STeP protocol as a standard teaching project in daily clinical routine and (ii) continue the pilot study to reach representative student and patient numbers for a possible final statement and derived recommendation.

    Relapse prevention in bipolar disorder can be improved by monitoring symptoms in patients' daily life. Smartphone apps are easy-to-use, low-cost tools that can be used to assess this information. To date, few studies have examined the usefulness of smartphone data for monitoring symptoms in bipolar disorder. We present results from a pilot test of a smartphone-based monitoring system, Social Information Monitoring for Patients with Bipolar Affective Disorder (SIMBA), that tracked daily mood, physical activity, and social communication in 13 patients. The objective of this study was to investigate whether smartphone measurements predicted clinical symptoms levels and clinical symptom change. The hypotheses that smartphone measurements are (1) negatively related to clinical depressive symptoms and (2) positively related to clinical manic symptoms were tested. Clinical rating scales were administered to assess clinical depressive and manic symptoms. Patients used a smartphone with the monitoring app for up to 12 months. Random-coefficient multilevel models were computed to analyze the relationship between smartphone data and externally rated manic and depressive symptoms. Overall clinical symptom levels and clinical symptom changes were predicted by separating between-patient and within-patient effects. Using established clinical thresholds from the literature, marginal effect plots displayed clinical relevance of smartphone data. Overall symptom levels and change in clinical symptoms were related to smartphone measures. Higher overall levels of clinical depressive symptoms were predicted by lower self-reported mood measured by the smartphone (beta=-.56, Psmartphone (ie, cell tower movements: beta=-.11, P=.03). Higher overall levels of clinical manic symptoms were predicted by lower physical activity on the smartphone (ie, distance travelled: beta=-.37, Psmartphone (beta=-.17, Psmartphone measurements, but not all smartphone measures predicted the occurrence of

    The aim of this study was to understand the impact of training with a hand robotic device on hand paresis and function in a population of children with hemiparesis. Twelve children with hemiparesis (mean age, 9 [SD, 3.64] years) completed participation in this prospective, experimental, pilot study. Participants underwent clinical assessments at baseline and again 6 weeks later with instructions to not initiate new therapies. After these assessments, participants received 6 weeks of training with a hand robotic device, consisting of 1-hour sessions, 3 times weekly. Assessments were repeated on completion of training. Results showed significant improvements after training on the Assisting Hand Assessment (mean difference, 2.0 Assisting Hand Assessment units; P = 0.011) and on the upper-extremity component of the Fugl-Meyer scale (raw score mean difference, 4.334; P = 0.001). No significant improvements between pretest and posttest were noted on the Jebsen-Taylor Test of Hand Function, the Quality of Upper Extremity Skills Test, or the Pediatric Evaluation of Disability Inventory after intervention. Total active mobility of digits and grip strength also failed to demonstrate significant changes after training. Participants tolerated training with the hand robotic device, and significant improvements in bimanual hand use, as well as impairment-based scales, were noted. Improvements were carried over into bimanual skills during play.

    The dental practice is associated with a high risk of infections, both for patients and healthcare operators, and the environment may play an important role in the transmission of infectious diseases. A microbiological environmental investigation was carried out in six dental clinics as a pilot study for a larger multicentre study that will be performed by the Italian SItI (Society of Hygiene, Preventive Medicine and Public Health) working group "Hygiene in Dentistry". Microbial contamination of water, air and surfaces was assessed in each clinic during the five working days of the week, before and during treatments. Air and surfaces were also examined at the end of the daily activity. A wide variation was found in microbial environmental contamination, both within the participating clinics and relative to the different sampling times. Microbial water contamination in Dental Unit Water Systems (DUWS) reached values of up to 26x10(4)cfu/mL (colony forming units per millilitre). P. aeruginosa was found in 33% of the sampled DUWS and Legionella spp. in 50%. A significant decrease in the Total Viable Count (TVC) was recorded during the activity. Microbial air contamination showed the highest levels during dental treatments and tended to decrease at the end of the working activity (p<0.05). Microbial buildup on surfaces increased significantly during the working hours. As these findings point out, research on microbial environmental contamination and the related risk factors in dental clinics should be expanded and should also be based on larger collections of data, in order to provide the essential knowledge aimed at targeted preventive interventions.

    2014-05-01

    The remotely piloted aircraft (RPA) MASC (Multipurpose Airborne Sensor Carrier) was developed at the University of Tübingen in cooperation with the University of Stuttgart, University of Applied Sciences Ostwestfalen-Lippe and 'ROKE-Modelle'. Its purpose is the investigation of thermodynamic processes in the atmospheric boundary layer (ABL), including observations of temperature, humidity and wind profiles, as well as the measurement of turbulent heat, moisture and momentum fluxes. The aircraft is electrically powered, has a maximum wingspan of 3.40 m and a total weight of 5-8 kg, depending on battery- and payload. The standard meteorological payload consists of temperature sensors, a humidity sensor, a flow probe, an inertial measurement unit and a GNSS. In normal operation, the aircraft is automatically controlled by the ROCS (Research Onboard Computer System) autopilot to be able to fly predefined paths at constant altitude and airspeed. Since 2010 the system has been tested and improved intensively. In September 2012 first comparative tests could successfully be performed at the Lindenberg observatory of Germany's National Meteorological Service (DWD). In 2013, several campaigns were done with the system, including fundamental boundary layer research, wind energy meteorology and assistive measurements to aerosol investigations. The results of a series of morning transition experiments in summer 2013 will be presented to demonstrate the capabilities of the measurement system. On several convective days between May and September, vertical soundings were done to record the evolution of the ABL in the early morning, from about one hour after sunrise, until noon. In between the soundings, flight legs of up to 1 km length were performed to measure turbulent statistics and fluxes at a constant altitude. With the help of surface flux measurements of a sonic anemometer, methods of similarity theory could be applied to the RPA flux measurements to compare them to

    Coal accounts for a major portion of our Nation's energy supply in projections for the future. A demonstrated reserve base of more than 475 billion short tons, as the Department of Energy currently estimates, indicates that, on the basis of today's rate of consumption, the United States has enough coal to meet projected energy needs for almost 200 years. However, the traditional procedures used for estimating the demonstrated reserve base do not account for many environmental and technological restrictions placed on coal mining. A new methodology has been developed to determine the quantity of coal that might actually be available for mining under current and foreseeable conditions. This methodology is unique in its approach, because it applies restrictions to the coal resource before it is mined. Previous methodologies incorporated restrictions into the recovery factor (a percentage), which was then globally applied to the reserve (minable coal) tonnage to derive a recoverable coal tonnage. None of the previous methodologies define the restrictions and their area and amount of impact specifically. Because these restrictions and their impacts are defined in this new methodology, it is possible to achieve more accurate and specific assessments of available resources. This methodology has been tested in a cooperative project between the U.S. Geological Survey and the Kentucky Geological Survey on the Matewan 7.5-minute quadrangle in eastern Kentucky. Pertinent geologic, mining, land-use, and technological data were collected, assimilated, and plotted. The National Coal Resources Data System was used as the repository for data, and its geographic information system software was applied to these data to eliminate restricted coal and quantify that which is available for mining. This methodology does not consider recovery factors or the economic factors that would be considered by a company before mining. Results of the pilot study indicate that, of the estimated

    Slipped capital femoral epiphysis (SCFE) is a common disorder of the growing hip; however, its etiology remains unknown. Vitamin D (25-OH) is a major regulator of bone homeostasis and calcium metabolism. Vitamin D deficiency is one of the major causes of rickets, and rickets has been associated with SCFE. Increased body mass index (BMI) has been linked to SCFE and obese children are known to have lower vitamin D levels. Therefore, we hypothesize that children who develop SCFE may have subclinical rickets predisposing them to the development of physeal disease. This was a pilot, prospective study designed to determine the relationship between vitamin D, bone, muscle, and fat in patients with SCFE. We enrolled 20 consecutive patients with idiopathic SCFE aged 9 to 14 years. Upon diagnosis, vitamin D, PTH, T4, and thyroid-stimulating hormone blood levels were obtained. A single-slice computed tomography was used to measure cortical bone density (CBD) of the femur. Demographics, BMI, and the results obtained were compared to generate a relationship between vitamin D levels and SCFE. Twenty patients were enrolled, 13 males and 7 females, at an average age of 12 years (range, 9 to 14 y), and mean BMI% was 93.9 (range, 81.3 to 99.5). There were 15 stable and 5 unstable SCFE. Overall, mean and SD values for vitamin D, 25-OH were within the normal range (43.9 ± 13.5). We found no difference in values in vitamin D between nonobese (BMI < 95%) and obese (BMI ≥ 95%) subjects (34.8 ± 16.8 vs. 51.6 ± 22.4, P = 0.144). Moreover, we found no difference in CBD between these 2 groups (1126 ± 33.1 vs. 1147 ± 41.2, P = 0.333). There was no relation between blood values of vitamin D and measures of CBD. Although obese children are known to have lower levels of vitamin D and a higher prevalence of SCFE, we found no correlation between low vitamin D and the development of SCFE in this subset of patients.

    This investigation presents the development and validation process of a scale whose principal purpose is to identify those areas in which one is required to achieve improved functioning and adequate emotional health resulting in improved sports performance with adolescent athletes. The "Hechavarria Wellness Scale for Adolescent Athletes" (HWSAA) was developed. The concept of wellness was measured utilizing the following 4 sub-scales measuring; depressive symptomatology, trait anxiety, self-esteem and social relations. A pilot study was undertaken with a universe of 149 adolescent athletes from both sexes with an average of 15.6 years old and residing within the different municipalities of Puerto Rico. The alpha coefficient reliability of the HWSAA and its' subscales fluctuated between 0.71 and 0.82. The results suggest that the HWSAA and its' subscales possess a psychometrically adequate internal consistency. This means that the instrument is valid and reliable for the sample utilized. We suggest further research with the HWSAA.

    As traditional family-based care in China declines, the demand for residential care increases. Knowledge of residents' experiences with long-term care (LTC) facilities is essential to improving quality of care. This pilot study aimed to describe residents' experiences in LTC facilities, particularly as it related to physical function. Semi-structured open-ended interviews were conducted in two facilities with residents stratified by three functional levels (n = 5). Directed content analysis was guided by the Adaptive Leadership Framework. A two-cycle coding approach was used with a first-cycle descriptive coding and second-cycle dramaturgical coding. Interviews provided examples of challenges faced by residents in meeting their daily care needs. Five themes emerged: staff care, care from family members, physical environment, other residents in the facility, and personal strategies. Findings demonstrate the significance of organizational context for care quality and reveal foci for future research. Copyright © 2017 Elsevier Inc. All rights reserved.

    A retrospective pilot clinical study on time domain multi-wavelength (635 to 1060 nm) optical mammography was exploited to assess collagen as a breast-cancer risk factor on a total of 109 subjects (53 healthy and 56 with malignant lesions). An increased cancer occurrence is observed on the 15% subset of patients with higher age-matched collagen content. Further, a similar clustering based on the percentage breast density leads to a different set of patients, possibly indicating collagen as a new independent breast cancer risk factor. If confirmed statistically and on larger numbers, these results could have huge impact on personalized diagnostics, health care systems, as well as on basic research.

    Structured dietary interventions have been associated with improved outcomes in adult weight-control programs, but virtually no research has focused on children. Thus, we conducted an uncontrolled pilot study to determine the potential utility of structured approaches to enhance the dietary component of family-based treatment of severe pediatric obesity (body mass index [BMI] >97th percentile for age and sex). Children aged 8-12 years participated with a parent or guardian. Individualized menu plans were provided (MENU, n =12) alone, or along with meals and snacks for the child (MENU+MEAL, n =6). All families received up to $30/week reimbursement for foods included in the menus. Median BMI change was -1.2 kg/m 2 for MENU ( n =12), and -1.8 kg/m 2 for MENU+MEAL ( n =6). Both approaches were associated with significant reductions in BMI ( p obesity are acceptable to families and warrant further development.

    Many authors have suggested adapting treatment programs to the specific needs of sexual abusers. However, little research has been conducted to understand what these patients seek in therapy or what elements play a key role in keeping them in treatment. In this pilot study, fifteen (N=15) pedophile sexual abusers from La Macaza clinic for sexual abusers were interviewed. Plan analysis was used to investigate the most prevalent components involved in staying in or leaving therapy. Results suggest that many components involved in the plans leading to doing and to avoiding treatment were similar. Differences were found in regards to the outcome of confrontations with the therapists, a tendency to isolate and overcomply, guilt related to the abuse, a need for a stable environment, and a need to be accepted. These results are discussed along with possible ways to improve the patients' involvement in treatment.

    A robust configuration of pilot points in the parameterisation step of a model is crucial to accurately obtain a satisfactory model performance. However, the recommendations provided by the majority of recent researchers on pilot-point use are considered somewhat impractical. In this study, a practical approach is proposed for using pilot-point properties (i.e. number, distance and distribution method) in the calibration step of a groundwater model. For the first time, the relative distance-area ratio ( d/ A) and head-zonation-based (HZB) method are introduced, to assign pilot points into the model domain by incorporating a user-friendly zone ratio. This study provides some insights into the trade-off between maximising and restricting the number of pilot points, and offers a relative basis for selecting the pilot-point properties and distribution method in the development of a physically based groundwater model. The grid-based (GB) method is found to perform comparably better than the HZB method in terms of model performance and computational time. When using the GB method, this study recommends a distance-area ratio of 0.05, a distance-x-grid length ratio ( d/ X grid) of 0.10, and a distance-y-grid length ratio ( d/ Y grid) of 0.20.

    Borderline personality disorder (BPD) is being increasingly recognized by clinicians working with adolescents, and the reliability and validity of the diagnosis have been established in the adolescent population. Adolescence is known to be a period of high risk for BPD development as most patients identify the onset of their symptoms to be in the adolescent period. As with other mental health disorders, personality disorder, are thought to result from the interaction between biological and environmental factors. Functional neuroimaging studies are reporting an increasing amount of data on abnormal neuronal functions in BPD adult patients. However, no functional neuroimaging studies have been conducted in adolescents with BPD.Objectives This pilot project aims to evaluate the feasibility of a functional magnetic resonance imaging (fMRI) study coupled with clinical and psychological measures in adolescent girls with a diagnosis of BPD. It also aims to identify neuronal regions of interest (ROI) for the study of BPD in adolescent girls.Method Six female adolescents meeting DSM-IV criteria for BPD and 6 female adolescents without psychiatric disorder were recruited. Both groups were evaluated for BPD symptoms, depressive symptoms, impulsivity, affective lability, and other potential psychiatric comorbidities. We used fMRI to compare patterns of regional brain activation between these two groups as they viewed 20 positive, 20 negative and 20 neutral emotion-inducing pictures, which were presented in random order.Results Participants were recruited over a period of 22 months. The protocol was well tolerated by participants. Mean age of the BPD group and control group was 15.8 ± 0.9 years-old and 15.5 ± 1.2 years-old respectively. Psychiatric comorbidity and use of medication was common among participants in the BPD group. This group showed higher impulsivity and affective lability scores. For the fMRI task, BPD patients demonstrated greater differences in activation

    Evidence-based practice is currently one of the most important developments in health care. Research in nursing science is rapidly growing; however, translating the knowledge based on this research into clinical practice is often hampered, and may be dependent on reflective skills. The aim of this study was to see how undergraduate nursing students in nursing should increase their skills and knowledge related to evidence-based practice through participation in clinical research projects. A qualitative approach was used in collecting and analyzing the data. Students participated in a pilot clinical research project and a received guidance related to their bachelor thesis. After the project was completed, all students filled in a questionnaire. The students' motivation to participate in this study was reported to be high, but they reported low knowledge related to evidence-based practice. All students reported that their attitude towards evidence-based practice changed in a positive direction during their participation in the project. Evidence-based practice influenced nursing practices by putting more focus on critical thinking, increasing pride and giving a sense of ownership in the clinical field. The curricula and the pedagogical perspectives in nursing education can influence the attitude towards evidence-based practice and skills among nursing bachelor students.

    Full Text Available The objective of this study was to analyze the effectiveness of motivational workshops to implement Evidence Based Practice (EBP among nursing leaders. This was a pilot, virtually experimental, before and after type study, conducted in a public teaching hospital. Researchers applied the Evidence-Based Practice Questionnaire and The Barriers to Research Utilization Scale and analyzed differences of means via Student’s t-test for paired samples or Wilcoxon’s test for non-parametric data. Although they had positive attitudes towards EBP, the workshops were not effective in broadening skills (initial mean=109.8; final mean=107, p=0.58. However, they significantly reduced the perception of barriers (initial mean=73.2; final mean=66.6, p<0.10, the main ones being related to the lack of authority to propose changes, and work overload. Researchers observed that the intervention was effective for motivational purposes. Conducting new research to assess the inclusion of this practice in units headed by nursing leaders is encouraged.

    Full Text Available European wine policy is a significant factor influencing winemakers in the European Union. This paper examines perception of this policy by winemakers and other persons working in Czech wine sector on the sample of respondents. Methodological triangulation consisting of non-structured interview and semantic differential was chosen. Field research was carried out, therefore the study uses primary data. Application of the methodology along with the method of evaluation of data creates an original approach which may be applied on several other research questions. General perception of European Wine Policy is complemented with its impact on competitiveness, practical running of vineyards and winery and on future development of winery. Data is statistically evaluated within categories of respondents. Special emphasis is placed on direct payments as a controversial factor of the policy. The policy is perceived as bureaucratic (“all respondents” x = 4.56, and among micro winemakers discriminating (x = 4.5, selfish (x = 4.5 and malfunctioning (x = 3.5. “Professional” winemakers perceive the impact on competitiveness in the Czech market as rather positive (x = 2.67. This study represents pilot research on perception of European Wine Policy by owners of wineries, viticulturists, micro winemakers, a sommelier and a representative of marketing-supporting institution, conducted in the Czech Republic. The author also outlines further direction of research, as the topic is not paid enough scientific attention.

    Photocatalytic water splitting with solar light is one of the most promising technologies for solar hydrogen production. From a systematic point of view, whether it is photocatalyst and reaction system development or the reactor-related design, the essentials could be summarized as: photon transfer limitations and mass transfer limitations (in the case of liquid phase reactions). Optimization of these two issues are therefore given special attention throughout our study. In this review, the state of the art for the research of photocatalytic hydrogen production, both outcomes and challenges in this field, were briefly reviewed. Research progress of our lab, from fundamental study of photocatalyst preparation to reactor configuration and pilot level demonstration, were introduced, showing the complete process of our effort for this technology to be economic viable in the near future. Our systematic and continuous study in this field lead to the development of a Compound Parabolic Concentrator (CPC) based photocatalytic hydrogen production solar rector for the first time. We have demonstrated the feasibility for efficient photocatalytic hydrogen production under direct solar light. The exiting challenges and difficulties for this technology to proceed from successful laboratory photocatalysis set-up up to an industrially relevant scale are also proposed. These issues have been the object of our research and would also be the direction of our study in future. (author)

    The New York City Energy-Water Integrated Planning Pilot Study is one of several projects funded by Sandia National Laboratories under the U.S. Department of Energy Energy-Water Nexus Program. These projects are intended to clarify some key issues and research needs identified during the Energy-Water Nexus Roadmapping activities. The objectives of the New York City Pilot Project are twofold: to identify energy-water nexus issues in an established urban area in conjunction with a group of key stakeholders and to define and apply an integrated energy and water decision support tool, as proof-of-concept, to one or more of these issues. During the course of this study, the Brookhaven National Laboratory project team worked very closely with members of a Pilot Project Steering Committee. The Steering Committee members brought a breadth of experience across the energy, water and climate disciplines, and all are well versed in the particular issues faced by an urban environment, and by New York City in particular. The first task was to identify energy-water issues of importance to New York City. This exercise was followed by discussion of the qualities and capabilities that an ideal decision support tool should display to address these issues. The decision was made to start with an existing energy model, the New York City version of the MARKAL model, developed originally at BNL and now used globally by many groups for energy analysis. MARKAL has the virtue of being well-vetted, transparent, and capable of calculating 'material' flows, such as water use by the energy system and energy requirements of water technology. The Steering Committee members defined five scenarios of interest, representing a broad spectrum of New York City energy-water issues. Brookhaven National Laboratory researchers developed a model framework (Water-MARKAL) at the desired level of detail to address the scenarios, and then attempted to gather the New York City-specific information

    De Cino, Thomas J., II

    In the aviation industry, digitally produced and presented flight, navigation, and aircraft information is commonly referred to as glass flight decks. Glass flight decks are driven by computer-based subsystems and have long been a part of military and commercial aviation sectors. Over the past 15 years, the General Aviation (GA) sector of the aviation industry has become a recent beneficiary of the rapid advancement of computer-based glass flight deck (GFD) systems. While providing the GA pilot considerable enhancements in the quality of information about the status and operations of the aircraft, training pilots on the use of glass flight decks is often delivered with traditional methods (e.g. textbooks, PowerPoint presentations, user manuals, and limited computer-based training modules). These training methods have been reported as less than desirable in learning to use the glass flight deck interface. Difficulties in achieving a complete understanding of functional and operational characteristics of the GFD systems, acquiring a full understanding of the interrelationships of the varied subsystems, and handling the wealth of flight information provided have been reported. Documented pilot concerns of poor user experience and satisfaction, and problems with the learning the complex and sophisticated interface of the GFD are additional issues with current pilot training approaches. A case study was executed to explore ways to improve training using GFD systems at a Midwestern aviation university. The researcher investigated if variations in instructional systems design and training methods for learning glass flight deck technology would affect the perceptions and attitudes of pilots of the learnability (an attribute of usability) of the glass flight deck interface. Specifically, this study investigated the effectiveness of scenario-based training (SBT) methods to potentially improve pilot knowledge and understanding of a GFD system, and overall pilot user

    Mobile phone-based data collection encompasses the richness of social network research. Both individual-level and network-level measures can be recorded. For example, health-related behaviors can be reported via mobile assessment. Social interactions can be assessed by phone-log data. Yet the potential of mobile phone data collection has largely been untapped. This is especially true of egocentric studies in public health settings where mobile phones can enhance both data collection and intervention delivery, e.g. mobile users can video chat with counselors. This is due in part to privacy issues and other barriers that are more difficult to address outside of academic settings where most mobile research to date has taken place. In this article, we aim to inform a broader discussion on mobile research. In particular, benefits and challenges to mobile phone-based data collection are highlighted through our mobile phone-based pilot study that was conducted on egocentric networks of 12 gay men (n = 44 total participants). HIV-transmission and general health behaviors were reported through a mobile phone-based daily assessment that was administered through study participants' own mobile phones. Phone log information was collected from gay men with Android phones. Benefits and challenges to mobile implementation are discussed, along with the application of multi-level models to the type of longitudinal egocentric data that we collected.

    Full Text Available Abstract Background In healthcare today, decisions are made in the face of serious resource constraints. Healthcare managers are struggling to provide high quality care, manage resources effectively, and meet changing patient needs. Healthcare managers who are constantly making difficult resource decisions desire a way to improve their priority setting processes. Despite the wealth of existing priority setting literature (for example, program budgeting and marginal analysis, accountability for reasonableness, the 'describe-evaluate-improve' strategy there are still no tools to evaluate how healthcare resources are prioritised. This paper describes the development and piloting of a process to evaluate priority setting in health institutions. The evaluation process was designed to examine the procedural and substantive dimensions of priority setting using a multi-methods approach, including a staff survey, decision-maker interviews, and document analysis. Methods The evaluation process was piloted in a mid-size community hospital in Ontario, Canada while its leaders worked through their annual budgeting process. Both qualitative and quantitative methods were used to analyze the data. Results The evaluation process was both applicable to the context and it captured the budgeting process. In general, the pilot test provided support for our evaluation process and our definition of success, (i.e., our conceptual framework. Conclusions The purpose of the evaluation process is to provide a simple, practical way for an organization to better understand what it means to achieve success in its priority setting activities and identify areas for improvement. In order for the process to be used by healthcare managers today, modification and contextualization of the process are anticipated. As the evaluation process is applied in more health care organizations or applied repeatedly in an organization, it may become more streamlined.

    Research indicates that promoting time spent in the outdoors and outdoor physical activity increases children's daily physical activity and improves health. One method showing promise is doctor prescriptions for outdoor physical activity for children; however, no empirical evidence currently exists on prescriptions for children's outdoor physical activity. A pilot study was conducted at one pediatric practice in western North Carolina during 2015 to test the feasibility and potential effectiveness of conducting an outdoor physical activity prescription program for children aged 5-13 years. Three pediatricians wrote prescriptions for children ( n  = 38), discussed benefits of outdoor physical activity, and provided information packets to parents on nearby places for physical activity. Parents of patients of five pediatricians served as control ( n  = 32). Prior to seeing a pediatrician, parents completed a baseline survey that asked height and weight, assessed their views of children's physical activity, and their personal and child's physical activity/sedentary behaviors. A nurse measured children's height and weight. Parents were emailed one-month and three-month follow-up surveys that asked the questions listed above. Changes in children's physical activity, outdoor physical activity, time spent in the outdoors, and sedentary activities were not significant between intervention and control groups. About half of parents (49%) viewed prescriptions as beneficial for their children and most used the intervention materials at home (70%). A larger study is needed to assess whether prescriptions increase children's physical activity. A critical examination of the intervention, pilot study design, and suggestions for a larger future study are provided.

    Implanted devices (eg, pacemakers and defibrillators) provide valuable information and may be interrogated to obtain diagnostic information and to direct management. During admission to an emergency department (ED), significant time and cost are spent waiting for device manufacturer representatives or cardiologists to access the data. If ED personnel could safely interrogate implanted devices, more rapid disposition could occur, thus leading to potentially better outcomes at a reduced cost. This was a pilot study examining the feasibility of ED device interrogation. This was a prospective convenience sample study of patients presenting to the ED with any chief complaint and who had an implantable device capable of being interrogated by a Medtronic reader. After obtaining informed consent, study patients underwent device interrogation by ED research personnel. After reviewing the device data, the physician documented their opinions of the value of data in aiding care. Patients were followed up at intervals ranging from 30 days out to 1 year to determine adverse events relating to interrogation. Forty-four patients underwent device interrogation. Their mean age was 56 ± 14.7 years (range, 28-83), 75% (33/44) were male and 75% (33/44) were hospitalized from the ED. The interrogations took less than 10 minutes 89% of the time. In 60% of the cases, ED physicians reported the data-assisted patient care. No adverse events were reported relating to the ED interrogations. In this pilot study, we found that ED personnel can safely and quickly interrogate implantable devices to obtain potentially useful clinical data.

    Binaural beat technology (BBT) products are sold internationally as personal development and health improvement tools. Producers suggest benefit from regular listening to binaural beats including reduced stress and anxiety, and increased focus, concentration, motivation, confidence, and depth in meditation. Binaural beats are auditory brainstem responses that originate in the superior olivary nucleus as a result of different frequency auditory stimuli provided to each ear. Listeners to binaural beat "hear" a beat at a frequency equal to the difference between the frequencies of the applied tones. The objectives of this pilot study were to gather preliminary data on psychologic and physiologic effects of 60 days daily use of BBT for hypothesis generation and to assess compliance, feasibility, and safety for future studies. Uncontrolled pilot study. Eight healthy adults participated in the study. Participants listened to a CD with delta (0-4 Hz) binaural beat frequencies daily for 60 days. Psychologic and physiological data were collected before and after a 60-day intervention. PSYCHOLOGIC: Depression (Beck Depression Inventory-2), anxiety (State-Trait Anxiety Inventory), mood (Profile of Mood States), absorption (Tellegen Absorption Scale) and quality of Life (World Health Organization-Quality of Life Inventory). PHYSIOLOGICAL: Cortisol, dehydroepiandrosterone, melatonin, insulin-like growth factor-1, serotonin, dopamine, epinephrine, norepinephrine, weight, blood pressure, high sensitivity C-reactive protein. There was a decrease in trait anxiety (p = 0.004), an increase in quality of life (p = 0.03), and a decrease in insulin-like growth factor-1 (p = 0.01) and dopamine (p = 0.02) observed between pre- and postintervention measurements. Binaural beat technology may exhibit positive effect on self-reported psychologic measures, especially anxiety. Further research is warranted to explore the effects on anxiety using a larger, randomized and controlled trial.

    Research has shown the efficacy of family-based behavioral interventions for overweight children, but a major difficulty is access to effective treatment programs. The objective of this study was to develop and test the initial feasibility and efficacy of a web-based family program for overweight 8- to 12-year-old children. A website was created using concepts from effective family-based behavioral programs and input from focus groups with overweight children, parents, and pediatricians. The website provided information about obesity and healthy lifestyles, assessment of dietary and physical activity habits, interactive dietary and physical activity games, and instruction in goal-setting and monitoring of goals. Children selected a dietary and physical activity goal and a daily step goal with pedometers. Feasibility and pilot testing over 4 weeks was conducted with 24 overweight children referred by a physician. Outcomes were z-BMI, healthy eating and physical activity, and intrinsic motivation and self-efficacy for weight control. Mean number of logins over the study period was 11.4 for the study sample. Eighteen families (75%) returned for the follow-up assessment. Pre-post analyses for these participants showed improvements in intrinsic motivation, (p=0.05), self-efficacy (p=0.025), physical activity (p=0.005), and healthy lifestyle behaviors (p=0.001). Comparisons between high and low users of the program indicated that high users reduced their BMI while low users increased their BMI over time (p=0.02); high users also improved their dietary intake relative to low users (p=0.04). Consumer satisfaction ratings were high. These pilot findings suggest this is a feasible approach for treatment of overweight children and that children who used the web program frequently improved their BMI and dietary intake.

    To conduct a pilot study to test the feasibility and acceptability of using children's books to understand caregiver perceptions of parenting practices around common behavior challenges. A prospective 1-month pilot study was conducted in 3 community-based pediatric clinics serving lower income families living in central Indianapolis. One hundred caregivers of 4- to 7-year-old children presenting for a well-child visit chose 1 of 3 available children's books that dealt with a behavioral concern the caregiver reported having with the child. The book was read aloud to the child in the caregiver's presence by a trained research assistant and given to the families to take home. Outcomes measured were caregiver intent to change their interaction with their child after the book reading, as well as caregiver reports of changes in caregiver-child interactions at 1 month. Reading the book took an average of 3 minutes. Most (71%) caregivers reported intent to change after the book reading; two-thirds (47/71) were able to identify a specific technique or example illustrated in the story. One month later, all caregivers remembered receiving the book, and 91% reported reading the book to their child and/or sharing it with someone else. Three-fourths of caregivers (60/80) reported a change in caregiver-child interactions. The distribution of children's books with positive parenting content is a feasible and promising tool, and further study is warranted to see whether these books can serve as an effective brief intervention in pediatric primary care practice.

    Full Text Available Abstract Background Substance use and poor dietary practices are prevalent among adolescents. The purpose of this study was to examine frequency of substance use and associations between cigarette, alcohol and marijuana use and selected dietary practices, such as sugar-sweetened beverages, high-fat foods, fruits and vegetables, and frequency of fast food restaurant use among alternative high school students. Associations between multi-substance use and the same dietary practices were also examined. Methods A convenience sample of adolescents (n = 145; 61% minority, 52% male attending six alternative high schools in the St Paul/Minneapolis metropolitan area completed baseline surveys. Students were participants in the Team COOL (Controlling Overweight and Obesity for Life pilot study, a group randomized obesity prevention pilot trial. Mixed model multivariate analyses procedures were used to assess associations of interest. Results Daily cigarette smoking was reported by 36% of students. Cigarette smoking was positively associated with consumption of regular soda (p = 0.019, high-fat foods (p = 0.037, and fast food restaurant use (p = 0.002. Alcohol (p = 0.005 and marijuana use (p = 0.035 were positively associated with high-fat food intake. With increasing numbers of substances, a positive trend was observed in high-fat food intake (p = 0.0003. There were no significant associations between substance use and fruit and vegetable intake. Conclusions Alternative high school students who use individual substances as well as multiple substances may be at high risk of unhealthful dietary practices. Comprehensive health interventions in alternative high schools have the potential of reducing health-compromising behaviors that are prevalent among this group of students. This study adds to the limited research examining substance use and diet among at-risk youth. Trial registration number ClinicalTrials.gov: NCT01315743

    Full Text Available This project focused on a pilot project implemented during the 2013-2014 academic year. The overall purpose was to facilitate interprofessional collaborative practice innovations through the development of leadership, core competencies, and the use of technology, especially among nurses. Nursing, medicine, and physician assistant students were educated on the IOM competencies for interprofessional teams and the core competencies identified by the Interprofessional Education Collaborative Expert Panel [1] to develop knowledge, skills, and attitudes needed to practice in the collaborative practice environments. The project addressed four goals: Develop faculty expertise and leadership in interprofessional collaborative practice to provide a current, high quality education to nursing, physician assistant, and medical students; Implement a culturally responsive and respectful collaborative interprofessional practice curriculum to prepare nurses, physician assistants, and medical students to deliver high quality, efficient, team-based care in a dynamically evolving environment; Focus interprofessional collaborative practice education on models and practices that lead to improvement in patient outcomes; and Evaluate the program and disseminate best practices. Findings from this pilot include strategies to engage different health professions' students and faculty, partnering with community agencies, building an effective interprofessional team to guide the project, and seeking funding for extension and expansion of the offerings.

    The purpose of this pilot study was to investigate the effectiveness of a mixed-reality (MR) exercise environment on engagement and enjoyment levels of individuals with spinal cord injury (SCI) and intellectual and developmental disabilities (IDD). Six people participated in this cross-sectional, observational pilot study involving one MR exercise trial. The augmented reality environment was based on a first-person perspective video of a scenic biking/walking trail in Colorado. Males and females (mean age, 43.3 ± 13.7 years) were recruited from a research database for their participation in previous clinical studies. Of the 6 participants, 2 had SCI, 2 had IDD, and 2 were without disability. The primary outcome measurement of this pilot study was the self-reported engagement and enjoyment level of each participant after the exercise trial. All participants reported increased levels of engagement, enjoyment, and immersion involving the MR exercise environment as well as positive feedback recommending this type of exercise approach to peers with similar disabilities. All the participants reported higher than normal levels of enjoyment and 66.7% reported higher than normal levels of being on a real trail. Participants' feedback suggested that the MR environment could be entertaining, motivating, and engaging for users with disabilities, resulting in a foundation for further development of this technology for use in individuals with cognitive and physical disabilities.

    Conventional approaches to participant recruitment are often inadequate in rare disease investigation. Social networking sites such as Facebook may provide a vehicle to circumvent common research limitations and pitfalls. We report our preliminary experience with Facebook-based methodology for participant recruitment and participation into an ongoing study of autoimmune hepatitis (AIH). The goal of our research was to conduct a pilot study to assess whether a Facebook-based methodology is capable of recruiting geographically widespread participants into AIH patient-oriented research and obtaining quality phenotypic data. We established a Facebook community, the Autoimmune Hepatitis Research Network (AHRN), in 2014 to provide a secure and reputable distillation of current literature and AIH research opportunities. Quarterly advertisements for our ongoing observational AIH study were posted on the AHRN over 2 years. Interested and self-reported AIH participants were subsequently enrolled after review of study materials and completion of an informed consent by our study coordinator. Participants returned completed study materials, including epidemiologic questionnaires and genetic material, to our facility via mail. Outside medical records were obtained and reviewed by a study physician. We successfully obtained all study materials from 29 participants with self-reported AIH within 2 years from 20 different states. Liver biopsy results were available for 90% (26/29) of participants, of which 81% (21/29) had findings consistent with AIH, 15% (4/29) were suggestive of AIH with features of primary biliary cholangitis (PBC), and 4% (1/29) had PBC alone. A total of 83% (24/29) had at least 2 of 3 proposed criteria: positive autoimmune markers, consistent histologic findings of AIH on liver biopsy, and reported treatment with immunosuppressant medications. Self-reported and physician records were discrepant for immunosuppressant medications or for AIH/PBC diagnoses in 4

    The vast numbers of studies regarding caloric restriction (CR) and breast cancer risk are based on war-related extreme situations. Studying the impact of CR in Jews during World War II (WW II) is challenging due to its variance and duration. To develop novel research tools in order to assess CR exposure in Jews that occurred more than 60 years ago during WW II. A pilot study based on Israeli women born in Europe in 1926-45, who lived there during WWII. Primary incident breast cancer patients and population-based controls were interviewed using a detailed questionnaire referring to demographic, obstetric factors and WW II experiences. Exposure to WWII-related CR was assessed by several proxy variables based on this information. The individual hunger score was higher in the exposed cases [mean score 141.06 vs. 130.07 in the controls). The same trend was observed for self perceived hunger score (mean score 2.75 in cases vs. 2.40 in controls) and hunger symptoms score (4.89 vs. 3.56, respectively). The novel research tools are appropriate for comparative assessment of CR exposure in case control studies.

    All sectors in health care are being asked to focus on the knowledge-to-practice gap, or knowledge translation, to increase service effectiveness. A social interaction approach to knowledge translation assumes that research evidence becomes integrated with previously held knowledge, and practitioners build on and co-create knowledge through mutual interactions. Knowledge translation strategies for public health have not provided anticipated positive changes in evidence-based practice, possibly due in part to a narrow conceptualization of knowledge. More work is needed to understand the role of tacit knowledge in decision-making and practice. This pilot study examined how health practitioners applied tacit knowledge in public health program planning and implementation. This study used a narrative approach, where teams from two public health units in Ontario, Canada were conveniently selected. Respondents participated in individual interviews and focus groups at each site. Questions were designed to understand the role of tacit knowledge as it related to the program planning process. Data were analyzed through a combination of content analysis and thematic comparison. The findings highlighted two major aspects of knowledge that arose: the use of tacit knowledge and the integration of tacit and explicit knowledge. Tacit knowledge included: past experiences, organization-specific knowledge, community contextual knowledge, and the recognition of the tacit knowledge of others. Explicit knowledge included: research literature, the Internet, popular magazines, formal assessments (surveys and interviews), legislation and regulations. Participants sometimes deliberately combined tacit and explicit knowledge sources in planning. This pilot demonstrated that front-line public health workers draw upon both tacit knowledge and explicit knowledge in their everyday lived reality. Further, tacit knowledge plays an important role in practitioners' interpretation and implementation

    Starting in the 1990s, there has been accumulating evidence of alexithymic characteristics in adult patients with primary headache. Little research has been conducted, however, on the relationship between alexithymia and primary headache in developmental age. In their research on alexithymia in the formative years, the authors identified one of the most promising prospects for research, as discussed here. The aim of this study was to verify whether there is: (a) a link between tension-type headache and alexithymia in childhood and early adolescence; and (b) a correlation between alexithymia in children/preadolescents and their mothers. This study was based on an experimental group of 32 patients (26 females and 6 males, aged from 8 to 15 years, mean 11.2 ± 2.0) suffering from tension-type headache and 32 control subjects (26 females and 6 males, aged from 8 to 15 years, mean 11.8 ± 1.6). Tension-type headache was diagnosed by applying the International Headache Classification (ICHD-II, 2004). The alexithymic construct was measured using an Italian version of the Alexithymia Questionnaire for Children in the case of the juvenile patients and the Toronto Alexithymia Scale (TAS-20) for their mothers. Higher rates of alexithymia were observed in the children/preadolescents in the experimental group (EG) than in the control group; in the EG there was no significant correlation between the alexithymia rates in the children/preadolescents and in their mothers.

    Children of parents with mental illness (COPMI) are at greater risk of developing mental disorders themselves. Since impaired parenting skills appear to be a crucial factor, we developed a facilitated 8-session preventative group course called KopOpOuders (Chin Up, Parents) delivered via the Internet to Dutch parents with psychiatric problems. The goal was to promote children's well-being by strengthening children's protective factors via their parents. To reach parents at an early stage of their parenting difficulties, the course is easily accessible online. The course is delivered in a secure chat room, and participation is anonymous. This paper reports on (1) the design and method of this online the group course and (2) the results of a pilot study that assessed parenting skills, parental sense of competence, child well-being, and course satisfaction. The pilot study had a pre/post design. Parenting skills were assessed using Laxness and Overreactivity subscales of the Parenting Scale (PS). Sense of parenting competence was measured with the Ouderlijke Opvattingen over Opvoeding (OOO) questionnaire, a Dutch scale assessing parental perceptions of parenting using the Feelings of Incompetence and Feelings of Competence subscales. Child well-being was assessed with the total problem score, Emotional Problems, and Hyperactivity subscales of the Strengths and Difficulties Questionnaire (SDQ). Paired samples t tests were performed, and Cohen's d was used to determine effect sizes. Intention-to-treat analyses and analyses of completers only were both performed. Course satisfaction was evaluated using custom-designed questionnaires. The sample comprised 48 parents with mental illness. The response rate was 100% (48/48) at pretest and 58% (28/48) at posttest. Significant improvements were found on PS Laxness and Overreactivity subscales (P children were not in the clinical range at both pretest and posttest. The mean course satisfaction score was 7.8 on a 10-point scale

    National guidelines in the United Kingdom recommend training Clinical Nurse Specialists in psychological skills to improve the assessment and intervention with psychological problems experienced by people with a cancer diagnosis (National Institute for Health and Clinical Excellence, 2004). This pilot study evaluated a three-day training program combined with supervision sessions from Clinical Psychologists that focused on developing skills in psychological assessment and intervention for common problems experienced by people with cancer. Questionnaires were developed to measure participants' levels of confidence in 15 competencies of psychological skills. Participants completed these prior to the program and on completion of the program. Summative evaluation was undertaken and results were compared. In addition, a focus group interview provided qualitative data of participants' experiences of the structure, process, and outcomes of the program. Following the program, participants rated their confidence in psychological assessment and skills associated with providing psychological support as having increased in all areas. This included improved knowledge of psychological theories, skills in assessment and intervention and accessing and using supervision appropriately. The largest increase was in providing psycho-education to support the coping strategies of patients and carers. Thematic analysis of interview data identified two main themes including learning experiences and program enhancements. The significance of the clinical supervision sessions as key learning opportunities, achieved through the development of a community of practice, emerged. Although this pilot study has limitations, the results suggest that a combined teaching and supervision program is effective in improving Clinical Nurse Specialists' confidence level in specific psychological skills. Participants' experiences highlighted suggestions for refinement and development of the program

    The objective of the present study was to determine emergency physicians' training, experience and perceptions as expert witnesses. Emergency physicians of an adult tertiary referral and teaching hospital participated in a pilot survey regarding their experiences in report writing and in court as expert witnesses. The 28-item survey also examined the amount of formalized forensic medical teaching that emergency physicians had received during their training. Of the participants, 41% (95% CI 21.6-64.1; 7/17) had never received any undergraduate or postgraduate training in forensic medicine, 11/17 (65%, 95% CI 41.2-82.8) had provided a written expert opinion for court, and 12/17 (71%, 95% CI 46.6-87.0) had attended court as an expert witness. All participants considered themselves 'skilled in attending an emergency resuscitation', whereas 3/13 (23%, 95% CI 7.5-50.9) considered themselves 'skilled in attending a courtroom trial'. Nearly 90% (95% CI 64.7-98.0; 15/17) thought that medical evidence training should be a requirement of emergency speciality training. The most commonly preferred forms of medical evidence training were mock court sessions (76%, 95% CI 52.2-91.0; 13/17) and forensic workshops (76%, 95% CI 52.2-91.0; 13/17). From 10 non-technical skills required of an EP, 'appearing in court as an expert witness' was perceived to be the second most difficult skill by most respondents. Emergency physicians in this pilot study have limited training for the role of expert witness and see it as one of the most difficult non-technical skills they have to perform. Further research is required regarding the current and future scope of forensic training.

    Full Text Available The purpose of this pilot study is to determine the feasibility of monitoring the progress of children with an autism spectrum disorder (ASD both in school and at home to promote a school-based integrated care model between parents, teachers, and medical providers. This is a prospective cohort study. To monitor progress, outcome measures were administered via an online platform developed for caregivers and teachers of children (n = 30 attending a school specializing in neurodevelopmental disorders and using an integrated medical and education program. Longitudinal analysis showed improvements in a novel scale, the Teacher Autism Progress Scale (TAPS, which was designed to measure key autism-related gains in a school environment (2.1-point improvement, p = 0.004, ES = 0.324. The TAPS showed a strong and statistically significant correlation, with improvement in aberrant behavior (r = −0.50; p = 0.008 and social responsiveness (r = −0.70; p < 0.001. The results also showed non-statistically significant improvements in aberrant behavior, social responsiveness, and quality of life over time at both school and home. To assess feasibility of ongoing progress measurement, we assessed missing data, which showed caregivers were more likely to miss surveys during summer. Results demonstrate the value and feasibility of online, longitudinal data collection in school to assist with individualized education planning and collaborative care for children with ASD. Lessons learned in this pilot will support school outcomes researchers in developing more efficacious, collaborative treatment plans between clinicians, caregivers, and teachers.

    Full Text Available Abstract Background The ME/CFS Disease Register is one of six subprojects within the National ME/CFS Observatory, a research programme funded by the Big Lottery Fund and sponsored by Action for ME. A pilot study in East Anglia, East Yorkshire, and London aimed to address the problem of identifying representative groups of subjects for research, in order to be able to draw conclusions applicable to the whole ME/CFS population. While not aiming for comprehensive population coverage, this pilot register sought to recruit participants with ME/CFS in an unbiased way from a large population base. Those recruited are constituting a cohort for long-term follow-up to shed light on prognosis, and a sampling frame for other studies. Findings Patients with unidentified chronic fatigue were identified in GP databases using a READ-code based algorithm, and conformity to certain case definitions for ME/CFS determined. 29 practices, covering a population aged 18 to 64 of 143,153, participated. 510 patients with unexplained chronic fatigue were identified. 265 of these conformed to one or more case definitions. 216 were invited to join the register; 160 agreed. 96.9% of participants conformed to the CDC 1994 (Fukuda definition; the Canadian definition defined more precisely a subset of these. The addition of an epidemiological case definition increased case ascertainment by approximately 4%. A small-scale study in a specialist referral service in East Anglia was also undertaken. There was little difference in pattern of conformity to case definitions, age or sex among disease register participants compared with subjects in a parallel epidemiological study who declined to participate. One-year follow-up of 50 subjects showed little change in pain or fatigue scores. There were some changes in conformity to case definitions. Conclusions Objective evaluation indicated that the aim of recruiting participants with ME/CFS to a Disease Register had been fulfilled, and

    The Compact Muon Solenoid (CMS) detector is one of two general-purpose detectors that measure the products of high energy particle interactions in the Large Hadron Collider (LHC) at CERN. The silicon pixel detector is the innermost component of the CMS tracking system. The detector which was in operation between 2009 and 2016 has now been replaced with an upgraded one in the beginning of 2017. During the previous shutdown period of the LHC, a prototype readout system and a third disk was inserted into the old forward pixel detector with eight prototype blades constructed using the new digital read-out chips. Testing the performance of these pilot modules enabled us to gain operational experience with the upgraded detector. In this paper, the reconstruction and analysis of the data taken with the new modules are presented including information on the calibration of the reconstruction software. The hit finding efficiency and track-hit residual distributions are also shown.

    Research registries are increasingly important in medical research and are essential to the mission of cancer centers. However, designing enrollment and data collection procedures that are consistent with ethical norms and regulatory requirements yet are efficient and cost effective is a major challenge. Current standard consent forms can be a barrier to enrollment because of their length, multiple components, and technical language. We pilot tested an IRB-approved registry booklet and simplified one-page, tiered consent form, allowing for choice of extent of participation. The booklet was mailed to patients with breast cancer as part of their routine information packet prior to the first clinic appointment. A research nurse met with 27 patients at initial treatment to review the booklet, answer questions, obtain informed consent, and collect quality of life data. The consent rate was 78% with 21 patients enrolling in the study. Twelve of the 21 patients (57%) did not read the booklet prior to the visit. The 9 patients (43%) who had read the booklet prior to arrival found it easy to understand. The multi-stage, simplified consent process and data collection were acceptable to these patients and readily integrated into clinical operations. An easy-to-read registry booklet may be an effective guide for discussion, but in-person consent procedures and further testing of the approach are required.

    To study associations between the cockpit environment, psychosocial work environment, home environment, and medical symptoms in a cohort of commercial pilots followed over 3 yr. A standardized questionnaire was mailed in February-March 1997 to all Stockholm-based pilots on duty in a Scandinavian flight company (N = 622); 577 (93%) participated. During this time smoking was allowed on long haul flights, but not on shorter flights. Smoking was prohibited on all flights after September 1997. The same questionnaire was sent to the cohort of 577 pilots in February-March 2000; 436 participated (76%). The questionnaire contained questions on symptoms, the psychosocial work environment, and the home environment. Associations were investigated using multiple logistic and ordinal regression. Symptoms were common, especially eye symptoms (38.5%), nose symptoms (39.9%), and tiredness (29.9%). Pilots exposed to environmental tobacco smoke (ETS) on long haul flights had more eye symptoms (odds ratio = 1.91) and tiredness (odds ratio = 2.73). These symptoms were reduced when no longer exposed to ETS. Those who started working on long haul flights developed more nose symptoms. Pilots reporting increased work demands developed more nose and dermal symptoms and tiredness and those with decreased work control developed more eye symptoms. Pilots living in new houses, multifamily houses, and in recently painted homes reported more symptoms. Eliminating ETS exposure on board reduced medical symptoms. Further work to reduce ETS exposure globally is needed. Psychosocial aspects of the work environment for commercial pilots should be considered, as well as the home environment.

    Full Text Available Abstract Background Most women delivering in South African State Maternity Hospitals do not have a childbirth companion; in addition, the quality of care could be better, and at times women are treated inhumanely. We piloted a multi-faceted intervention to encourage uptake of childbirth companions in state hospitals, and hypothesised that lay carers would improve the behaviour of health professionals. Methods We conducted a pilot randomised controlled trial of an intervention to promote childbirth companions in hospital deliveries. We promoted evidence-based information for maternity staff at 10 hospitals through access to the World Health Organization Reproductive Health Library (RHL, computer hardware and training to all ten hospitals. We surveyed 200 women at each site, measuring companionship, and indicators of good obstetric practice and humanity of care. Five hospitals were then randomly allocated to receive an educational intervention to promote childbirth companions, and we surveyed all hospitals again at eight months through a repeat survey of postnatal women. Changes in median values between intervention and control hospitals were examined. Results At baseline, the majority of hospitals did not allow a companion, or access to food or fluids. A third of women were given an episiotomy. Some women were shouted at (17.7%, N = 2085, and a few reported being slapped or struck (4.3%, N = 2080. Despite an initial positive response from staff to the childbirth companion intervention, we detected no difference between intervention and control hospitals in relation to whether a companion was allowed by nursing staff, good obstetric practice or humanity of care. Conclusion The quality and humanity of care in these state hospitals needs to improve. Introducing childbirth companions was more difficult than we anticipated, particularly in under-resourced health care systems with frequent staff changes.

    Mission X: Train Like an Astronaut is an international educational challenge focusing on fitness and nutrition as we encourage students to "train like an astronaut." Teams of students (aged 8-12) learn principles of healthy eating and exercise, compete for points by finishing training modules, and get excited about their future as "fit explorers." The 18 core exercises (targeting strength, endurance, coordination, balance, spatial awareness, and more) involve the same types of skills that astronauts learn in their training and use in spaceflight. This first-of-its-kind cooperative outreach program has allowed 14 space agencies and various partner institutions to work together to address quality health/fitness education, challenge students to be more physically active, increase awareness of the importance of lifelong health and fitness, teach students how fitness plays a vital role in human performance for exploration, and inspire and motivate students to pursue careers in STEM fields. The project was initiated in 2009 in response to a request by the International Space Life Sciences Working Group. USA, Netherlands, Italy, France, Germany, Austria, Colombia, Spain, and United Kingdom hosted teams for the pilot this past spring, and Japan held a modified version of the challenge. Several more agencies provided input into the preparations. Competing on 131 teams, more than 3700 students from 40 cities worldwide participated in the first round of Mission X. OUTCOMES AND BEST PRACTICES Members of the Mission X core team will highlight the outcomes of this international educational outreach pilot project, show video highlights of the challenge, provide the working group s initial assessment of the project and discuss the future potential of the effort. The team will also discuss ideas and best practices for international partnership in education outreach efforts from various agency perspectives and experiences

    To pilot test the Birth Unit Design Spatial Evaluation Tool (BUDSET) in an Australian maternity care setting to determine whether such an instrument can measure the optimality of different birth settings. Optimally designed spaces to give birth are likely to influence a woman's ability to experience physiologically normal labor and birth. This is important in the current industrialized environment, where increased caesarean section rates are causing concerns. The measurement of an optimal birth space is currently impossible, because there are limited tools available. A quantitative study was undertaken to pilot test the discriminant ability of the BUDSET in eight maternity units in New South Wales, Australia. Five auditors trained in the use of the BUDSET assessed the birth units using the BUDSET, which is based on 18 design principles and is divided into four domains (Fear Cascade, Facility, Aesthetics, and Support) with three to eight assessable items in each. Data were independently collected in eight birth units. Values for each of the domains were aggregated to provide an overall Optimality Score for each birth unit. A range of Optimality Scores was derived for each of the birth units (from 51 to 77 out of a possible 100 points). The BUDSET identified units with low-scoring domains. Essentially these were older units and conventional labor ward settings. The BUDSET provides a way to assess the optimality of birth units and determine which domain areas may need improvement. There is potential for improvements to existing birth spaces, and considerable improvement can be made with simple low-cost modifications. Further research is needed to validate the tool.

  13. Evaluating care from a care ethical perspective:: A pilot study.

    Care ethical theories provide an excellent opening for evaluation of healthcare practices since searching for (moments of) good care from a moral perspective is central to care ethics. However, a fruitful way to translate care ethical insights into measurable criteria and how to measure these criteria has as yet been unexplored: this study describes one of the first attempts. To investigate whether the emotional touchpoint method is suitable for evaluating care from a care ethical perspective. An adapted version of the emotional touchpoint interview method was used. Touchpoints represent the key moments to the experience of receiving care, where the patient recalls being touched emotionally or cognitively. Participants and research context: Interviews were conducted at three different care settings: a hospital, mental healthcare institution and care facility for older people. A total of 31 participants (29 patients and 2 relatives) took part in the study. Ethical considerations: The research was found not to be subject to the (Dutch) Medical Research Involving Human Subjects Act. A three-step care ethical evaluation model was developed and described using two touchpoints as examples. A focus group meeting showed that the method was considered of great value for partaking institutions in comparison with existing methods. Reflection and discussion: Considering existing methods to evaluate quality of care, the touchpoint method belongs to the category of instruments which evaluate the patient experience. The touchpoint method distinguishes itself because no pre-defined categories are used but the values of patients are followed, which is an essential issue from a care ethical perspective. The method portrays the insider perspective of patients and thereby contributes to humanizing care. The touchpoint method is a valuable instrument for evaluating care; it generates evaluation data about the core care ethical principle of responsiveness.

    This article presents a pilot study of the use of two new tangible interfaces and virtual worlds for teaching geometry in a secondary school. The first tangible device allows the user to control a virtual object in six degrees of freedom. The second tangible device is used to modify virtual objects, changing attributes such as position, size, rotation and color. A pilot study on using these devices was carried out at the "Florida Secundaria" high school. A virtual world was built where students used the tangible interfaces to manipulate geometrical figures in order to learn different geometrical concepts. The pilot experiment results suggest that the use of tangible interfaces and virtual worlds allowed a more meaningful learning (concepts learnt were more durable).

    Full Text Available This article presents a pilot study of the use of two new tangible interfaces and virtual worlds for teaching geometry in a secondary school. The first tangible device allows the user to control a virtual object in six degrees of freedom. The second tangible device is used to modify virtual objects, changing attributes such as position, size, rotation and color. A pilot study on using these devices was carried out at the “Florida Secundaria” high school. A virtual world was built where students used the tangible interfaces to manipulate geometrical figures in order to learn different geometrical concepts. The pilot experiment results suggest that the use of tangible interfaces and virtual worlds allowed a more meaningful learning (concepts learnt were more durable.

    The purpose of this report is to document progress in state-level programs in energy efficiency financing programs that are linked with home energy rating systems. Case studies are presented of programs in five states using a federal pilot program to amortize the costs of home energy improvements. The case studies present background information, describe the states` program, list preliminary evaluation data and findings, and discuss problems and solution encountered in the programs. A comparison of experiences in pilot states will be used to provide guidelines for program implementers, federal agencies, and Congress. 5 refs.

    The Resource Allocation Support System (RASS) is a decision-aiding system being developed to assist the US Department of Energy's (DOE's) Office of Waste Management in program and budget decision making. Four pilot studies were conducted at DOE field offices in summer 1992 to evaluate and improve the RASS design. This report summarizes the combined results of the individual field office pilot studies. Results are presented from different perspectives to illustrate the type of information that would be available from RASS. Lessons learned and directions for future RASS developments are also presented
