    PROBLEM ADDRESSED Family physicians are not adequately following the 2002 Osteoporosis Canada guidelines for providing optimal care to patients with osteoporosis. OBJECTIVE OF PROGRAM The Canadian Quality Circle (CQC) pilot project was developed to assess the feasibility of the CQC project design and to gather informationfor implementing a national study of quality circles (QCs). The national study would assess whether use ofQCs could improve family physicians’ adherence to the osteoporosis guidelines. PROGRAM DESCRIPTION The pilot project enrolled 52 family physicians and involved 7 QCs. The project had 3 phases: training and baseline data collection, educational intervention and follow-up data collection, and sessions on implementing strategies for care. CONCLUSION Findings from the pilot study showed that the CQC project was well designed and well received. Use of QCs appeared to be feasible for transferring knowledge and giving physicians an opportunity to analyze work-related problems and develop solutions to them. PMID:17934033

    Full Text Available Abstract Background While the Osteoporosis Canada 2002 Canadian guidelines provided evidence based strategies in preventing, diagnosing, and managing this condition, publication and distribution of guidelines have not, in and of themselves, been shown to alter physicians clinical approaches. We hypothesize that primary care physicians enrolled in the Quality Circle project would change their patient management of osteoporosis in terms of awareness of osteoporosis risk factors and bone mineral density testing in accordance with the guidelines. Methods The project consisted of five Quality Circle phases that included: 1 Training & Baseline Data Collection, 2 First Educational Intervention & First Follow-Up Data Collection 3 First Strategy Implementation Session, 4 Final Educational Intervention & Final Follow-up Data Collection, and 5 Final Strategy Implementation Session. A total of 340 circle members formed 34 quality circles and participated in the study. The generalized estimating equations approach was used to model physician awareness of risk factors for osteoporosis and appropriate utilization of bone mineral density testing pre and post educational intervention (first year of the study. Odds ratios (OR and 95% confidence intervals (95% CI were calculated. Results After the 1st year of the study, physicians' certainty of their patients' risk factor status increased. Certainty varied from an OR of 1.4 (95% CI: 1.1, 1.8 for prior vertebral fracture status to 6.3 (95% CI: 2.3, 17.9 for prior hip fracture status. Furthermore, bone mineral density testing increased in high risk as compared with low risk patients (OR: 1.4; 95% CI: 1.2, 1.7. Conclusion Quality Circle methodology was successful in increasing both physicians' awareness of osteoporosis risk factors and appropriate bone mineral density testing in accordance with the 2002 Canadian guidelines.

    1995-08-01

    In the beginning of 1993, society of panel doctors Südbaden, Germany, has constituted a group of experts from the Department of General Medicine of the university hospital and practising general practitioners (GPs) to develop an organisational and conceptional framework for setting up quality circles. At present, 23 quality circles with 6-12 participants are holding regular meetings every 4 to 8 weeks in the region of Südbaden. The group members, who are all physicians working in primary health care, are selecting and discussion topics which are important in general practice. In order to facilitate the discussions, the research group has developed predefined guidelines covering a wide range of common and important conditions in general practice (Hypertension, sleeping disorders, diabetes mellitus, COPD, dementia, lower back pain, cardio-vascular disease, depression, headache, vertigo etc). In presenting these structurized guidelines, the moderator prompts and encourage the group members to identify common problems in their own practices. The use of these guidelines in, quality circles and research may provide a starting point for developing consensus guidelines. The quality circle projects is given as systematic evaluation for both participants and moderators at different levels. Main objectives of the assessment are the recruitment, motivation and the specific goals of general practitioners to participate in quality circles. Currently, we are evaluating the development of quality circle for a period of 18 months.

    2010-01-01

    The discussion about the advantages of evidence-based guidelines in daily dental practice is a matter of current interest. In this report three high-quality S3 level pilot guidelines which have been developed in dental medicine were evaluated under practice conditions. Quality circles in the city of Hamburg readily accepted to join this survey. By means of a questionnaire before and after a 4-month field test in dental practices the participants of quality circles were interviewed about their attitude towards guidelines and to the application of the guidelines. In addition, the experience gained with the application of the guidelines was incorporated into a group discussion with moderators of quality circles. The inclusion of quantitative and qualitative methods enabled a recording of the complete range of differentiated opinions concerning the application of guidelines. The results show that the concerns expressed by participants can be reduced by integrating guidelines in their everyday clinical practice. A strength and weakness analysis demonstrates that the quality circle moderators' attitudes towards approved guidelines range from rather positive to ambivalent. Field testing by quality circles proves to be a sound method for evaluating the acceptance of guidelines in daily practice. Copyright © 2009. Published by Elsevier GmbH.

    It is a fundamental principle of continuous quality improvement (CQI) that processes should be the objects of quality improvement. The objective of this study was to improve process quality concerning the prevention of hospital-acquired infections in surgical departments and intensive care units by a continuous quality improvement (CQI) approach based mainly on quality circles. This approach was evaluated in a prospective controlled intervention study in medium-size acute care hospitals (four intervention and four control hospitals). During two intervention periods (each 10 months) four external physicians with training in hospital epidemiology and infection control introduced and supervised quality circles in the intervention hospitals. Process quality was assessed by interviewing senior staff members before the first and after the second intervention period using standardized questionnaires. The gold standard process quality was defined on the basis of the CDC/HICPAC-guidelines for the prevention of hospital-acquired infections. Most of the evaluated aspects of process quality belonged to the HICPAC-categories IA and IB respectively, the CDC category I. Fifty quality circle sessions were performed in the four intervention hospitals of which 28 were dealing directly with key subjects in infection control. In the intervention hospitals, 19.8% of evaluated aspects of process quality which concerned the prevention of hospital-acquired infections were improved compared to only 6.9% in the control hospitals (Pquality were initiated by the results of the quality circles. Our study demonstrates that a CQI approach based on infection control quality circles can lead to a substantial improvement of process quality regarding the prevention of hospital-acquired infections.

    Several quality assurance initiatives in health care have been undertaken during the past years. The next step consists of systematically combining single initiatives in order to built up a strategic quality management. In a German multicenter study, the quality of inpatient depression treatment was measured in ten psychiatric hospitals. Half of the hospitals received comparative feedback on their individual results in comparison to the other hospitals (bench marking). Those bench markings were used by each hospital as a statistic basis for in-house quality work, to improve the quality of depression treatment. According to hospital differences concerning procedure and outcome, different goals were chosen. There were also differences with respect to structural characteristics, strategies, and outcome. The feedback from participants about data-based quality circles in general and the availability of bench-marking data was positive. The necessity of carefully choosing quality circle members and professional moderation became obvious. Data-based quality circles including bench-marking have proven to be useful for quality management in inpatient depression care.

    2006-08-01

    Drug replacement therapy using synthetic opioids is in Vienna mostly carried out by primary care physicians. Group teaching in quality assurance groups has been installed in order to give these doctors the necessary personal and informational assistance. Evaluation has shown that: 1. 90% of the doctors were highly or well satisfied with the teaching. Only 10% were slightly critical. 2. They could better communicate with, and were able to show more tolerance towards, the "difficult" patients. 3. Specialized knowledge increased (risk of infection, "management of hepatitis", contact with authorities, co-medication). 4. Some critical remarks pointed towards ways in which this particular further education could in future be better organized and dealt with more intensively.

    In response to residents' reports of inefficiencies in the Veterans Administration (VA) system, a temporary task force of quality control circles was implemented at a VA hospital. A total of 25 internal medicine residents, on rotation at the VA, were subdivided into four groups. Each group was presented with a different problem, given the components and constraints of the problem, and asked to identify possible solutions. Program results were submitted to the hospital administration. Efforts are now being made to improve the working environment for medical residents.

    Quality circles are considered a key method for quality assurance in health care. However, there is a lack of systematic evaluation for quality circles in general practice, especially regarding the process quality of quality circle work. This article presents the results of an interaction analysis completing the systematic evaluation of quality circles in general practice in a region of south Germany. Using the so-called conference encoding method for interaction analysis we analyzed 7 out of 25 evaluated quality circles and 2348 interactions between the quality circle members. The participation rate of the moderators is high compared to the relative low contribution of the group members to the quality circle work. We could show that quality circles work topic-oriented, there is a wide exchange of experience between the group members and the group climate is positive. However, there were almost no specific activities to develop guidelines for diagnostic and therapeutic procedures. The results showed a significant discrepancy between the aims of quality circles and their practical realisation. Besides improved option for information and training programs for moderators and participants, we recommend further evaluation studies complemented with specific analysis of the process quality for example with the conference encoding method.

    The main objectives of this study were to implement quality circle programs among general practitioners and to evaluate this quality management tool as a way to develop clinical guidelines in general practice. The quality circle program was evaluated within a formative and summative evaluation design by both participants and moderators for a period of 18 months using structured questionnaires. At time one, participants were asked about their goals and current job satisfaction, and rated the perceived effectiveness and the usefulness of predefined guidelines of each quality circle meeting. At time two, participants and moderators reported again about their achieved goals and job satisfaction. Two hundred and forty-three general practitioners in a district of South Germany (Südbaden), in 25 quality circle groups participated. Demographic variables of the participating physicians, quality circle goals, job satisfaction, usefulness of guidelines and perceived effectiveness of the quality circle process were collected. One hundred and six quality circle meetings were evaluated. When asked to rank the goals of quality circle work, participants provided the highest rankings for improvement of the doctor-doctor relationship, agreeing on consensus for diagnostic procedures and therapy management, and developing local guidelines. The comparison between time one and time two ratings provided evidence for an increase in overall job satisfaction. Higher benefit is correlated with more regular participation in quality circle meetings. Working with predefined guidelines is both feasible and effective in quality circles and may provide a starting point for developing guidelines in primary care. There is some empirical evidence that participating in quality circles may increase general practitioners' job satisfaction. Further studies using intervention and control group designs should investigate whether quality circles really improve daily practice through clinical audit and

    Within the framework of their quality assurance programme, the German statutory pension funds in 1994 and 1995 required over 400 rehabilitation hospitals to develop structures permitting to establish comprehensive quality management programmes. In particular, they asked that these hospitals should establish quality circles. Structured information could be gathered from 380 hospitals at the end of a pilot phase. According to this information, 233 hospitals conduct a total of 558 quality circles. However, only 23.5% of these quality circles fulfil the criteria of a well-structured quality circle. Another 34.7% of the reported activities can, in a broader sense, be considered as activities that might be helpful in developing Total Quality Management (TQM) systems, whereas 41.8% account for more routine activities such as floor meetings etc. A detailed analysis of the documented information revealed that a high proportion of quality circle participants are recruited from leadership positions. From a subject matter perspective, quality circles still focus on their conceptualization. Taking into consideration the large number of hospitals, the introduction of quality circles can be considered quite successful.

    Quality circles comprise small group sessions of doctors and written feedback on their individual practice patterns. Although 50% of German primary care doctors participate in quality circles, their effectiveness has hardly been evaluated in Germany. This study determined the impact of a large-scale programme of quality circles on quality and costs of prescribing. A controlled before-after study was performed, in which primary care doctors were allocated to a quality circles group or a control group. Subjects were 100,000 patients in 1996 and in 1998, who had visited one of 177 doctors in the 3 month registration periods in one region in Germany. The intervention comprised a quality circles programme, comprising 11 sessions and repeated feedback on prescribing. Main outcome measures were proportion of patients who received a prescription, mean prescription costs per patient and proportion of generic prescriptions. The absolute numbers of prescriptions decreased in both groups, but the mean prescription costs per patient increased. The quality circles reduced the proportion of patients who received a prescription (OR = 0.86) and the mean prescription costs per patient (B = -3.99 euro), while it increased the proportion of generic drugs (OR = 1.10). The intervention had intended effects on four of the 15 secondary indicators. Large-scale application of quality circles had intended effects on prescribing decisions in primary care in Germany. The effects found in this study may reflect better what improvements can be achieved than randomized trials of similar interventions.

    Quality circles in the classroom setting are composed of students who meet regularly to identify, analyse and solve problems related to a course, and implement solutions. We recently instituted quality circles (QCs) among preclinical medical students and evaluated their impact on quality of learning and student satisfaction. Included in the study were all 135 first-year medical students of Trakya University School of Medicine in the 2000-2001 academic year. Six students were selected randomly out of 26 volunteers as circle members. Circle participants met once a week for 14 45-minute sessions to discuss educational issues, propose solutions and prepare a report for submission to the dean. A questionnaire was administered to all first-year students and the replies provided the problem pool from which the QC chose the problem to be addressed. A total of 22 problems concerned education and 28 were identified in the fields of accommodation, social activities and other issues. To evaluate the change in the perceived quality of learning, circle members prepared a questionnaire designed to compare satisfaction at the beginning and end of the study period. This questionnaire was composed of 26 items and evaluated various aspects of education. There was a significant increase in student satisfaction after the one-year study period (p = 0.001). In addition to enhancing quality of learning, quality circles improved student satisfaction as well. More studies should be conducted to test the impact of QCs on education in different settings and different classes. Our results show that the use of quality circles in first-year medical students improves quality of learning and student satisfaction.

    Quality circles (peer review) are a process of a continuous, systematic and critical reflection of care providers on their own and colleagues' performance by using structured procedures with the aim of achieving a continuous improvement. Main goal of the topic-oriented quality circle model in Sudbaden (Germany) is the development of guidelines for primary health care. The quality circle programme of the society of health insurances of Sudbaden is currently given a systematic evaluation. The results presented refer to 246 participants and moderators of 25 groups who have completed questionnaires. Attention is given to the general goals of the doctors participating in quality circle groups. When asked about the most important goals of peer review the participants scored the highest ranking on (1) exchanging practice experiences with colleagues (2) the personal reflection of one's way of working (3) agreeing on guidelines and targets for desirable performance and (4) developing guidelines for general practice. From the results, conclusions regarding the concept of quality circles and the methods for developing practice guidelines are drawn.

The seminars aim to train techniques of moderating a group and to give a methodological background for the work with quality circles. 65 (44.2%) of the 147 participants were general practitioners, 34 (23.1%) were internists and 32 (21.8%) were specialists of other disciplines. 16 (10.9%) were not physicians or not working as a physician. An evaluation of the seminars by a structured questionnaire showed mean ratings of 2.1 for lectures [in terms of school-marks from 1 (very good) to 6 (very poor)] and 1.8 for the work in small groups. Working atmosphere and opportunities for active participation were rated most positively. 6 months after the course, 64.9% of the participants already had arranged dates for meetings or had started with own quality circles.

    Guideline adherence of general practitioners (GP) regarding treatment of chronic conditions shows room for improvement. Thus, concepts have to be designed to promote quality of care. The aim of the interventional study "Improvement of Quality by Benchmarking" was to assess whether quality can be improved by self-auditing, benchmarking and quality circles in Salzburg (Austria) and South Tyrol (Italy). In this publication we present the Austrian results. Quality indicators were developed in a consensus process for eight chronic diseases based on pre-existing quality management systems. A quality score consisting of 35 indicators was calculated (0-5 points per indicator depending on fulfilment, maximum 175 points). Data were extracted from the electronic health records of participating practices in 2012, 2013 and 2014. A statistical pre-post analysis was performed using Wilcoxon signed-rank tests. A total of 20 GPs participated in the project. The mean quality score increased from 62.0 at baseline to 84.0 at the second follow-up (p = 0.003). Regarding the individual quality indicators, strong improvements were achieved between baseline and first follow-up, especially in process indicators concerning documentation. Between the first and second follow-up, quality remained in most cases at the same level. The validity of results is limited because of structural and technical problems. Due to the uncontrolled pre-post design we cannot exclude external influences on the results. Nevertheless, the intervention was able to improve measured quality of care. Barriers were detected that should be considered in a possible implementation of quality control programs.

    Quality circles, as a participatory management technique, offer one alternative for dealing with frustration and discontent of today's workers. This study was conducted to investigate the effect of implementation of quality circles on nurses' quality of work-life and job satisfaction. In this study, two emergency medical services (EMS) of Hamedan province were selected and randomly assigned as the experimental and control groups. After the experimental group was trained and quality circles were established in this group, the levels of quality of work-life and job satisfaction were measured in the two groups. Then, the statistical analyses were performed using t-test. After the intervention, the results showed significant differences between the scores of motivational factors (p=0.001), the total scores of job satisfaction (p=0.003), and the scores of some quality of work life (QWL) conceptual categories including the use and development of capacities (p=0.008), the total space of life (p=0.003), and the total scores of QWL (p=0.031) in the experimental group compared to those in the control group. This study confirms the effectiveness of quality circles in improving quality of work-life and job satisfaction of nurses working in EMS, and offers their application as a management method that can be used by EMS managers.

    We used quality control circles (QCC) followed by the PDCA Deming cycle and analyzed the application of QCC to the sustained improvement of a medical institution in Zhejiang province. Analyses of the tangible and intangible achievements of QCC revealed that the achievement indices for reductions in internal errors, reductions in costs, improvements in the degree of patient satisfaction, improvements in work quality, and improvements in economic performance were 109.84% ± 16.47%, 135.04% ± 50.33%, 126.26% ± 53.69%, 100.58% ± 22.83%, and 104.07% ± 5.45%, respectively. The improvements in these areas were 61.12% ± 13.2%, 60.47% ± 28.91%, 34.41% ± 22.96%, 49.22% ± 25.39%, and 73.70% ± 5.24%, respectively. The intangible achievements were reflected as follows: 5% of QCC members showed an activity growth value of 1-2 points, 83% 1-2 points, 12% more than 2 points. As a result, QCC activity showed prominent results in fostering long-lasting improvement in the quality of medical institutions in terms of both tangible and intangible factors. In short, QCC can be used as an effective tool to improve medical quality.

    The important role of pediatricians in private practice for the care of psychologically noticeable children makes it seem necessary to implement quality assurance measures. As part of an integrated project for quality assurance in psychosomatic basic care the pediatricians in the medical care district Göttingen were offered two quality circles for two years which in contrast to the original concept were conducted by child psychiatrists. The evaluation of this offer by the participating pediatricians after one year (n = 16) and after the end (n = 15) yielded very positive results regarding the structural characteristics of the quality circles (such as length of sessions, subject selection, moderation, working atmosphere) and also the general usefulness of such a quality assurance measure. The increase in competence regarding practical skills (diagnostics, treatment in the own practice, referee indication, forming the physician-patient relationship) however, was evaluated as being less pronounced. The attractiveness of a quality circle modified by continuously integrating a child psychiatrist/psychotherapist was confirmed by the results of a national survey. In another survey the participating pediatricians documented cases where they suspected psychological problems before the quality circles began and after the first year. Sensitivity and specificity of the pediatricians' assessments increased at the second evaluation point which is a sign for an increased diagnostic competency of pediatricians.

    To determine the effectiveness of quality circles on prescribing patterns of primary care physicians in Germany and to explore the influence of specific factors on changes. Three large non-randomised comparative studies were performed in primary care in Germany, with baseline measurements in 2001 and follow-up measurements in 2003. 1090 physicians were in intervention groups and 2090 physicians in control groups. For each physician, data on 444 patients and 1201 prescriptions were available, on average, at each measurement moment. Quality circles comprising of a series of small group moderated meetings of physicians, provision of evidence-based information and repeated written feedback on individual prescribing patterns. Compared to the control groups, physicians in the intervention groups reduced mean prescription cost per patient per 3-month period by 1.87 euro (95%CI 0.51 to 3.22), increased generic drugs of all potentially generic prescriptions by 0.75% (95%CI 0.40 to 1.10), increased prescription of recommended lipid lowering drugs by 4.24% (95%CI 2.40 to 6.10), increased the prescription of recommended antibiotics by 1.72% (95%CI 0.33 to 3.10). Groups with more positive views of performance feedback, evidence-based indicators and price comparisons showed more change of prescribing. Quality circles had a modest effect on prescribing quality and costs. If widely implemented, they could have nationwide impact on the quality and costs of prescribing in primary care.

    The purpose of this cluster-randomised controlled trial was to evaluate the efficacy of quality circles (QCs) working either with general data-based feedback or with an open benchmark within the field of asthma care and drug-drug interactions. Twelve QCs, involving 96 general practitioners from 85 practices, were randomised. Six QCs worked with traditional anonymous feedback and six with an open benchmark. Two QC meetings supported with feedback reports were held covering the topics "drug-drug interactions" and "asthma"; in both cases discussions were guided by a trained moderator. Outcome measures included health-related quality of life and patient satisfaction with treatment, asthma severity and number of potentially inappropriate drug combinations as well as the general practitioners' satisfaction in relation to the performance of the QC. A significant improvement in the treatment of asthma was observed in both trial arms. However, there was only a slight improvement regarding inappropriate drug combinations. There were no relevant differences between the group with open benchmark (B-QC) and traditional quality circles (T-QC). The physicians' satisfaction with the QC performance was significantly higher in the T-QCs. General practitioners seem to take a critical perspective about open benchmarking in quality circles. Caution should be used when implementing benchmarking in a quality circle as it did not improve healthcare when compared to the traditional procedure with anonymised comparisons. Copyright © 2011.

    The integration of available early interventions and healthcare for families with children by practicing pediatricians has yet to be systematically established. For this reason, the Association of Statutory Health Insurance Physicians of Baden-Wuerttemberg established overarching, accredited, cross-system quality circles that serve to integrate all representatives of the healthcare system as well as child and youth welfare services. These quality circles are led by specially trained moderator tandems consisting of pediatricians and staff members from youth welfare services. The goal was to evaluate the endpoints of the regional implementation of cross-system quality circles for early interventions in the state of Baden-Wuerttemberg as well as the feasibility of establishing long-term training programs for cross-system moderator tandems. This was a noncontrolled, longitudinal study to prepare a yearly evaluation of the quality-circle assessments as well as to gather statistics on the training of the moderator tandems within the Association of Statutory Health Insurance Physicians of Baden-Wuerttemberg. A total of 59 moderator tandems were trained in nine separate training sessions within the project period from 2011 to 2015. Overall, 33 quality circles were founded. In 2015, 566 persons were participating in the respective circles. Over the course of the study between 26 and 33 of the 44 urban and rural districts in the state of Baden-Wuerttemberg had at least one quality circle dedicated to early interventions. Ten further circles are presently in the process of being founded; 29 moderators have yet to commence their activity or have withdrawn from the program. Between 59 and 81 % of the urban and rural districts implemented cross-system quality circles. The training of the moderator tandems proceeded without complications. Because of the dropout quota of the trained moderator tandems, systematic and continual training of new tandems proves to be

    In industry, especially in the automobile industry, improvements in efficiency could be demonstrated by quality management and quality circles. There is no doubt that in medicine, major trauma is also a very complex challenge.The German Association for Trauma Surgery published the White Paper on the Management of the Seriously Injured in 2006. The White Paper specifies the demand for quality of care, sets the level of structural requirements for trauma care and postulates the cooperation of regional hospitals within a network of dedicated trauma centres. The Trauma Network Eastern Bavaria (TNO) was the first certified trauma network in Germany. One of the reasons for this success is the fact that cooperation between trauma surgeons has already had a long tradition in this geographic area. The key factor is communication which is supported by all technical and organisational means. The formal installation of quality circles on each level of trauma care, e.g. within and across institutions, was accepted by all partners within the network. The goal is the improvement of patient care in trauma above and beyond the guidelines of the White Paper. This paper shows the instruments used to enhance the quality of trauma care within a network.

    Supply management has been shown to increase the price of milk. Technological change has induced (and allowed) processors to substitute alternative inputs, many of which can be imported tariff-free, for the traditional ingredients to lower costs and maximize profit. Meanwhile, there has been a great deal of consolidation in the dairy processing industry. We analyse the effect of these trends on cheese quality by measuring the increase in casein imports. Results suggest that supply management ...

    Physicians-pharmacists quality circles (PPQCs) were introduced in 1997-98 by visionary healthcare practitioners of the French-speaking part of Switzerland with the aim to improve the quality of drug prescription. Indeed the challenge is to manage the 7917 brand names of the Swiss drug market (2010), including 19793 different dosages, galenic formulations and packaging. The impact of these PPQCs on the containment of drug costs and on drug prescribing profiles has been demonstrated and has led to their spread throughout Switzerland. PPQCs provide clear educational benefits and have thus been accredited by various continuous education bodies. In this article, participating physicians and pharmacists share their vision and illustrate how they work and influence the safety and efficiency of drug prescription, a routine process complex enough to warrant sharing of its burden in a constructive interdisciplinary collaboration.

    1996-08-01

    In Saxonia, an agreement of shared care was reached between health insurances and the society of general practitioners with the objective to have a better medical care for patients with diabetes mellitus. This model of shared care means integrated medical care for out-patient diabetics between general practitioner and specialists. It must be accompanied by quality assurance measures. After a training of moderators according to a structured programme of the Central Research Institute for Outpatient Health Care, quality circles started with seven to ten members and two moderators in five Saxonian cities in May 1994. General practitioners interactively improved their medical knowledge about diabetes mellitus during five sessions with two hours each. The regional specialist participated in the first and the last session. He also answered open questions left in a mail box. Based on patient data the following results were achieved: 553 documentations.

    Quality Control Circles (QCC's) meet regularly to solve limited, but important, problems related directly to their work. The QCC is organized so that the worker becomes involved in problem solving and quality awareness in meaningful and creative ways. Participation is voluntary. This concept has been successfully used in Japan for two decades. QCC's are now being implemented at an accelerating rate world-wide. There are questions as to QCC's applicability in the United States and in particular with respect to an R and D facility such as Sandia. This paper summarizes information about the QCC concept with respect to its implementation and applicability to Sandia. Information was extracted from 66 sources as noted in an Annotated Bibliography. Analysis techniques used by QCC's were utilized in the construction of this paper, especially with the Annotated Bibliography.

    Quality circles (QCs) are well established as a means of aiding doctors. New quality improvement strategies include benchmarking activities. The aim of this paper was to evaluate the efficacy of QCs for asthma care working either with general feedback or with an open benchmark. Twelve QCs, involving 96 general practitioners, were organized in a randomized controlled trial. Six worked with traditional anonymous feedback and six with an open benchmark; both had guided discussion from a trained moderator. Forty-three primary care practices agreed to give out questionnaires to patients to evaluate the efficacy of QCs. A total of 256 patients participated in the survey, of whom 185 (72.3%) responded to the follow-up 1 year later. Use of inhaled steroids at baseline was high (69%) and self-management low (asthma education 27%, individual emergency plan 8%, and peak flow meter at home 21%). Guideline adherence in drug treatment increased (P = 0.19), and asthma steps improved (P = 0.02). Delivery of individual emergency plans increased (P = 0.008), and unscheduled emergency visits decreased (P = 0.064). There was no change in asthma education and peak flow meter usage. High medication guideline adherence was associated with reduced emergency visits (OR 0.24; 95% CI 0.07-0.89). Use of theophylline was associated with hospitalization (OR 7.1; 95% CI 1.5-34.3) and emergency visits (OR 4.9; 95% CI 1.6-14.7). There was no difference between traditional and benchmarking QCs. Quality circles working with individualized feedback are effective at improving asthma care. The trial may have been underpowered to detect specific benchmarking effects. Further research is necessary to evaluate strategies for improving the self-management of asthma patients.

    To investigate how to shorten patient wait times between continuous ocular operations and to evaluate the influence of a quality control circle (QCC) on operating room management. QCC management was established to conduct activities. Clinical data were collected to analyze the causes of long wait times between continuous surgeries. Effective measures were undertaken correspondingly. The staff from QCC actively undertook measures that would significantly shorten patient wait times between continuous ocular surgeries (P < 0.05). Multiple measures, such as setting up a QCC, enhancing the arrangement of surgical procedures, establishing effective communication channels, optimizing human resources, and integrating the use of instruments, can effectively shorten patient wait times between continuous vitreous or retinal surgeries.

    Continuing medical education is essential to improve the quality of health care delivery. The efficacy of postgraduate medical education generally improves when participants feel that their specific needs are met by a particular educational activity. Audit circles of general practitioners allow for a discussion of relevant issues. The present paper describes a novel concept for delivering knowledge and skills in arthritis and rheumatic conditions to general practitioners. A well-designed paper case was used for discussion in established audit circles of general practitioners, and a specially trained expert rheumatologist participated as an external expert to answer all those questions that could not be solved by the other participants. The participation of such as an expert-on-demand was found extremely helpful, as an evaluation during pilot sessions in 6 pre-existing audit circles of general practitioners revealed.

    A U.S. consumer (n = 642) study (Baltimore, MD; Phoenix, AZ; and Lubbock, TX) was conducted to compare consumer sensory scores of U.S. beef (83 USDA Choice [Choice] and 96 USDA Select [Select]) and Canadian beef (77 AAA and 82 AA) strip loins. Strip loins (n = 338) were obtained from beef processors in Canada and the United States and were wet aged until 21 d postmortem at 2°C. Marbling scores were assigned at 21 d and loins were paired according to quality grades and marbling score. Strip loins were fabricated into 2.54-cm thick steaks; steaks were vacuum packaged and frozen until further evaluations. Proximate analysis was performed to compare fat, moisture, and protein. Choice and Canadian AAA had similar marbling scores and intramuscular fat. Both Choice and Canadian AAA had greater (P grades (P > 0.05). Consumers' opinions did not differ when comparing equivalent grades (Choice with Canadian AAA and Select with Canadian AA), but they rated Choice and Canadian AAA more palatable than Select and Canadian AA for all sensory attributes (P grade carcasses (Choice and Canadian AAA) than lower quality grade carcasses (Select and Canada AA). Additionally, consumers gave their opinion of Canadian beef, where its quality and safety were rated as "good" to "excellent" for both attributes (76.72% and 88.36%, respectively; P grades; however, strip loin steaks from higher quality grades were more palatable than lower quality grades according to consumer scores for eating quality traits.

    2012-08-01

    In Austria, the participation of general practitioners (GPs) in so-called 'quality circles for pharmacotherapy' (QCPs) was taken as a special approach to increase the use of generics and possibly, to improve the quality and efficiency of prescribing patterns in primary care. This study aimes at exploring GPs' perception of QCPs whether they think that taking part has helped to change their prescribing habits, their opinions on generics in general and the issues that arise for them in attempting to promote their use. Qualitative analysis was used to evaluate QCP protocols for their potential to evoke discussion in the group and for their relevance to our study questions. Of the 821 self-employed GPs in Vienna under contract with the Vienna District Health Insurance Fund 445 took part at least once in the study period. Seven main topics, which provide insight into various aspects of patient care in primary care, were identified: QCPs work, generic drug prescription, problems related to the sale of generics, patient counselling and education, therapy adherence, coordination of care, competence and medical education. From all prescribed drugs for which generics were available in the fourth quarter of the year 2003 GPs prescribed 33.91% generics, in the fourth quarter of 2004 43.97%, in the fourth quarter of 2005 46.31%, and in the fourth quarter of 2006 49.88%. Peer review groups can be an important method of quality improvement in GPs' prescribing behaviour in favour of generics. QCPs also facilitate the exchange between GPs on problems encountered and provide feedback to policy makers. © 2011 Blackwell Publishing Ltd.

    Evaluation by Participants: For a project aimed at improving the prescribing performance of general practitioners (GPs) in Northern Hessia, 53 GPs who exceeded average prescribing costs by more than 20% were approached. 32 agreed to participate in 10 peer-review group meetings and to discuss an analysis of their own prescriptions issued during a three-months period. These 32 GPs in three quality circles as an intervention group were compared with a group of 15 GPs as a "gold standard" who had been working for two years already on other items than rational prescribing and who had not had any problems with prescribing costs. Apart from positive effects in changing actual prescribing behaviour, discussed elsewhere, an evaluation of the group work by participants in structured questionnaires and open discussions revealed differences between the intervention and the "gold standard" groups. Members of the intervention group had to overcome feelings of being controlled by the authorities in the first session, and felt less satisfied with the effect of the group work on their daily work in practice. This article discusses matters of working in groups, and points out the importance of volunteer participation.

    To study the attitudes of ambulatory care physicians towards quality improvement, the intentions to join quality circles (QCs, peer review groups) and the expectations directed towards them. Survey with a five-page questionnaire posted to all ambulatory care physicians in the German states of Saxony-Anhalt (n = 3139) and Bremen (n = 1131). Response rates were 61.8% in Saxony-Anhalt and 41.7% in Bremen. 2412 questionnaires were available in this largest survey on that topic in Germany. Necessity of quality improvement (QI) in ambulatory care was approved by the majority of the respondents (1.7 on a 5-point Lickert scale). Concerns existed about a rise in control and the risk of abuse of QI measures. 56.4% in Saxony-Anhalt and 52.3% in Bremen had the intention to join a QC. Motives and impediments of participation in QCs were investigated by content analysis. A causal dominance analysis was performed to identify the key elements for the decision to participate. The main benefits of QC-participation were expected as assistance in daily practice and exchange of experiences. The major obstacles were professional and private duties, fear of control and inefficiency. Policies that could be adequate to rise motivations and tackle on widespread fears should be purposely adapted to the needs and expectations of the physicians.

    Currently there are more than 40 centres in Canada that perform more than 65,000 percutaneous coronary interventions (PCIs) in a year. Considering the high volume of procedures and number of operators, the potential for variation in processes of care is high, and might lead to variation in the quality of care. As part of its quality initiative, the Canadian Cardiovascular Society convened a working group to develop a set of PCI Quality Indicators (QIs) that would be relevant, scientifically acceptable, and feasible to measure and report. The working group was comprised of clinical experts from across Canada and members of provincial and federal organizations involved in promoting the quality of health care. Using the Canadian Cardiovascular Society "Best Practices for Developing Cardiovascular Quality Indicators" methodology, a total of 23 QIs were proposed. Subsequent ranking and discussion led to the selection of 8 QIs. The selection and ranking of QIs were on the basis of clinical importance and relevance, scientific acceptability, and feasibility of their operationalization at a national level. The data definitions and technical notes of the QIs were refined after feasibility testing and Web consultation. Feasibility testing indicated that standardization and enhancements of knowledge infrastructure are essential to provide the comprehensive patient data necessary to evaluate the quality of PCI across Canada.

    An intercomparison programme was carried out as part of the quality management of medical assessments in the public health service in Baden-Württemberg. All physicians who performed medical assessments in January 1997 were invited to participate. They received a case description adopted from medical records of a precedent case (56-year-old head of a department in an administrative authority, severely disabled after left-sided stroke with residual right-sided partial hemiparesis, reduced work performance), and were asked to assess whether the patient was permanently unable to work. Access to medical expert opinions was requested. Participation was voluntary. Assessments were reviewed twice as to whether five prospectively defined evaluation criteria were fully met, or only partially or not at all. Participants and reviewers remained unknown to each other. Among 246 eligible physicians, 103 returned an assessment (43%). Forty-five respondents had requested additional expert opinions. Anticipations for five criteria were met to their full extent with regard to: formal construction, all submissions; case description, 84%; sociomedical diagnosis, 65%; description of ability to work, 53%; and response to the question posed, 75% of submissions. The programme required considerable work time in its preparatory, field, and evaluation phases. The procedure was however found to be practicable, and a suitable element within a quality management programme can contribute towards motivation, quality assurance and the identification of possible deficits, and thus indicate possible topics and issues for continuing education and quality control programmes.

    To survey the quantitative development of quality circles (peer review groups; QC) and their moderators in ambulatory care in Germany, to describe approaches to documentation and evaluation, to establish what types of facilities and support is available and to assess opinions on the future importance of QC. Cross-sectional survey using a standardized questionnaire and supplementary telephone interviews. All 23 German regional Associations of Statutory Health Insurance Physicians (ASHIP) were surveyed. The total number of QC in ambulatory care in Germany increased rapidly from 16 in 1993 to 1633 in June 1996, with about 17% (range 1.0-52.1%) of all practicing physicians (112 158) currently involved. Throughout Germany, 2403 moderators were trained in 168 training courses by the qualifying date. Follow-up meetings were held or being planned in 20 ASHIP, with approximately 39% (23-95%) of the moderators participating. Systematic documentation of QC work was undertaken or planned in all 23 ASHIIP, and 10 ASHIP carried out comparative evaluation, with at least five others planning to start it. The ASHIP promoted the work of QC by providing organizational (22) or financial (20) support, materials (20) or mediation of resource persons (16). Eleven ASHIP received grants from drug companies. ASHIP rated the future importance of QC as increasing (18) or stable (four), but in no case as decreasing. The quantitative growth of QC in Germany is encouraging, but the extent of support and evaluation appears insufficient. Increased methodological support and facilitation, follow-up meetings on a more regular basis, improved documentation and evaluation of individual QC, and problem oriented evaluation of their impact on health care are essential for further successful development. Principles, problems and solutions discussed may be relevant for similar QI activities in other countries.

  9. Exploring why quality circles work in primary health care: a realist review protocol.

    2013-12-09

    Quality circles (QCs) are commonly used in primary health care in Europe to consider and improve standard practice over time. They represent a complex social intervention that occurs within the fast-changing system of primary health care. Numerous controlled trials, reviews, and studies have shown small but unpredictable positive effect sizes on behavior change. Although QCs seem to be effective, stakeholders have difficulty understanding how the results are achieved and in generalizing the results with confidence. They also lack understanding of the active components of QCs which result in changes in the behavior of health care professionals. This protocol for a realist synthesis will examine how configurations of components and the contextual features of QCs influence their performance. Stakeholder interviews and a scoping search revealed the processes of QCs and helped to describe their core components and underlying theories. After clarifying their historical and geographical distribution, a purposive and systematic search was developed to identify relevant papers to answer the research questions, which are: understanding why, how, and when QCs work, over what time frame, and in what circumstances. After selecting and abstracting appropriate data, configurations of contexts and mechanisms which influence the outcome of QCs within each study will be identified. Studies will be grouped by similar propositional statements in order to identify patterns and validation from stakeholders sought. Finally, theories will be explored in order to explain these patterns and to help stakeholders maintain and improve QC performance. Analyzing context-mechanism-outcome (CMO) patterns will reveal how QCs work and how contextual factors interact to influence their outcome. The aim is to investigate unique configurations that enable them to improve the performance of health care professionals. Using a standardized reporting system, this realist review will allow the research

    A study to determine the protein digestibility-corrected amino acid score and protein efficiency ratio of nine different cooked Canadian pulse classes was conducted in support of the establishment of protein quality claims in Canada and the United States. Split green and yellow pea, whole green lentil, split red lentil, Kabuli chickpea, navy bean, pinto bean, light red kidney bean, and black bean were investigated. Protein digestibility-corrected amino acid score (PDCAAS) and the protein efficiency ratio (PER) were determined using the appropriate rodent models. All pulses had high digestibility values, >70%, with PDCAAS values greater than 0.5, thereby qualifying as a quality protein in the United States, but only navy beans qualified as a good source of protein. All pulses except whole green lentils, split red lentils, and split green peas would qualify as sources of protein with protein ratings between 20 and 30.4 in Canada. These findings support the use of pulses as protein sources in the regulatory context of both the United States and Canada.

    2010-03-01

    The implementation of the general practitioners' (GPs) guideline for palliative care released in 2007 with consent of the developing group was accompanied by an anonymous and voluntary survey designed to assess acceptance and feasibility of the recommendations. 60 quality circles of the GP-based care program in Hesse which are run by the PMV research group were used for guideline implementation. The quality of the palliative care quality circle meeting itself was checked with a standardized questionnaire (feedback, n = 473 of 515 participating GPs). After several weeks, the follow-up questioning on acceptance of the corresponding guideline was performed (n = 391 of 440 attendees) using twelve items to evaluate the guideline recommendations. The closed questions were appraised employing a Likert scale and the open questions after classifying the free text in categories. 96% of the respondents considered palliative medicine to be important in daily routine. The majority agreed with form and content of this CME meeting (feedback, response rate 91%). The complexity, handling, and practical relevance of the guideline were evaluated positively (response rate 88%). 82% of GPs reported that they would recommend the guideline to colleagues. Specific, practical guideline recommendations on (non)pharmacological strategies in treating dyspnea, on reducing xerostomia and on comedication in the case of opioid treatment were confirmed by 80-94% of the participants, and 75-92% rated these recommendations as practical. The relevance of palliative care in daily routine was shown by the responses evaluating the quality circle session. The grade of acceptance of the guideline is comparable to the other GPs' guidelines with focus on pharmacotherapy. 10-13% of the respondents were not able to judge the relevance nor the practicability of selected recommendations. Future implementation should therefore consider attitude and experience with palliative care. To date, the questionnaires

    Full Text Available This paper is about changes in the business world. The main goal is to study the implications related to people’s creativity expression owing to work organization in small groups in the Ambev S.C. branch. This is a qualitative study based on a case study. 21 self-management circles and 18 quality control circles in the organization were found. The self management circles are responsible for achieving the organizational main goals and the quality control circles to bring best practices and new ideas. The result shows that quality control circles are more powerful than the self management circles as a space to develop people creativity and organizational innovation. It is relevant to stress that in the CCQs there are more multidisciplinary and common purpose guided to a collective objective desired by all the members of the team. On the other hand, in the CGA´s there are more discipline to accept the common tactics to people reach the objectives of the group and the corporative aims. The conclusion is that the changes in the business environment make the small work group very important to a company’s creativity and a fundamental strategy differentiation in the process of work organization in the context of the business world.

    In recent years, the growth of population and increase of the industries around the tributaries of Yamchi Dam basin have led to deterioration of dam water quality. This study aimed to evaluate the quality of the Yamchi Dam basin water, which is used for drinking and irrigation consumptions using Canadian Water Quality Index (CWQI) model, and to determine the main water pollution sources of this basin. Initially, nine sampling stations were selected in the sensitive locations of the mentioned basin's tributaries, and 12 physico-chemical parameters and 2 biological parameters were measured. The CWQI for drinking consumptions was under 40 at all the stations indicating a poor water quality for drinking consumptions. On the other hand, the CWQI was 62-100 for irrigation at different stations; thus, the water had an excellent to fair quality for irrigation consumptions. Almost in all the stations, the quality of irrigation and drinking water in cold season was better. Besides, for drinking use, total coliform and fecal coliform had the highest frequency of failure, and total coliform had the maximum deviation from the specified objective. For irrigation use, total suspended solids had the highest frequency of failure and deviation from the objective in most of the stations. The pisciculture center, aquaculture center, and the Nir City wastewater discharge were determined as the main pollution sources of the Yamchi Dam basin. Therefore, to improve the water quality in this important surface water resource, urban and industrial wastewater treatment prior to disposal and more stringent environmental legislations are recommended.

    The aim of the study was to analyse the influence of prevention measures on pressure injuries for high-risk patients and to establish the most appropriate methods of implementation. Nurses assessed patients using a checklist and factors influencing the prevention of a pressure injury determined by brain storming. A specific series of measures was drawn up and an estimate of risk of pressure injury determined using the Braden Scale, analysis of nursing documents, implementation of prevention measures for pressure sores and awareness of the system both before and after carrying out a quality control circle (QCC) process. The overall scores of implementation of prevention measures ranged from 74.86 ± 14.24 to 87.06 ± 17.04, a result that was statistically significant (P control. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Full Text Available The aim of the investigation is to perform comparative analysis of the quality assessment and policies of quality assurance in postsecondary education in Canada and Russian Federation.Methods. The theoretical methods involve comparative analysis and synthesis, induction and deduction, extrapolation and modelling.Results. Russia and Canada have different policies on quality assurance in the distance learning and are at different stages of implementation of distance learning into postsecondary curricula. The Canadian system of postsecondary education is regulated not by the State but by professional societies, licensing organisations, and experts. Canadian postsecondary institutions have efficient systems of quality assurance, quality standards and accreditation. Blended learning is widely used in Canadian medical schools and is mandatory for continuous professional development. In Russia, the system of quality assurance for distance learning is regulated by the State. At present, Russia has developed policies on distance learning but unified quality standards in this field are absent. Blended learning is used in the medical schools but its implementation has just begun as continuous professional development.Scientific novelty. For the first time, the results of comparative analysis of the policies on quality assurance in distance learning in Russia and Canada are described.Practical significance. This research has showed the needs of the development of the system of quality standards and the policy on quality assurance of distance learning in the Russia postsecondary education.

    To evaluate the effect on antibiotic prescribing of an intervention in existing local quality circles promoting an evidence-based guideline for acute rhinosinusitis. A pragmatic cluster-randomised controlled trial comparing standard dissemination of the guideline by mail with an additional strategy using quality circles. General practice in Flanders, Belgium. General practitioners (GPs) in 18 local quality circles were randomly allocated to two study arms. All GPs received the guideline by mail. GPs in the nine quality circles allocated to the intervention arm received an additional group intervention, which consisted of one self-led meeting using material introduced to the group moderator by a member of the research team. Adherence to the guideline was measured as differences in the proportion of antibiotic prescriptions, including the choice of antibiotic, between the two study arms after the intervention period. GPs registered their encounters with patients presenting with signs and symptoms of acute rhinosinusitis in a booklet designed for the study. A total of 75 doctors (29% of GPs in the participating quality circles) registered 408 consultations. In the intervention group, 56.9% of patients received an antibiotic compared with 58.3% in the control group. First-choice antibiotics were issued in 34.5% of antibiotic prescriptions in the intervention group compared with 29.4% in the control group. After adjusting for patient and GP characteristics, the ORadj for antibiotics prescribed in the intervention arm compared with the control arm was 0.63 (95% CI 0.29 to 1.37). There was no effect on the choice of antibiotic (ORadj 1.07, 95% CI 0.34 to 3.37). A single intervention in quality circles of GPs integrated in the group's normal working procedure did not have a significant effect on the quality of antibiotic prescribing. More attention to the context and structure of primary care practice, and insight into the process of self-reflective learning may provide

    To develop indicators based on prescription analysis in order to assess adherence using guidelines and to monitor prescribing behavior. SETTING AND MATERIAL: Eleven pharmacotherapeutic circles (PTC) of the Association of Statutory Health Insurance Physicians (KV Hesse; 10 PTCs including 155 GPs as participants, mostly high prescribers; one circle with 11 moderators trained in pharmacology). These provided a total of 183,997 drug prescriptions involving 54,970 patients (prescriptions reimbursed by the substitute fund--Ersatzkassen--II. quarter 2000); claims form from 151 GPs. On average, 5.1% of the patients with prescriptions received lipid-lowering drugs. Development and application of indicators based on the guideline for the treatment of hypercholesterolemia developed by a GP's guideline group of the quality circles in Hesse (Hausärztliche Leitliniengruppe Hessen). The ratio of prescribing for primary and secondary prevention was chosen as a top indicator for measuring adherence to the guideline. Prescribing for secondary prevention was assessed by a set of special diagnoses. The second indicator relates to patient groups (here: older than 75 years) where the benefit of prescribing is not clear. Further indicators measure the prescribing of first choice drugs, avoidance of risk combinations and costconscious prescribing. The indicators are presented in the prescription analysis and will be discussed during the circle meeting. On average, the moderators prescribed 34% of the lipid-lowering drugs for primary prevention, the GP circle participants 36.7%. On average, moderators and GP participants prescribed lipid-lowering drugs for 4.9% and 7.5% of patients older than 75 years, respectively (6% and 22% in primary prevention). Approximately, 28% of all lipid-lowering drugs issued by the participants involved simvastatin and pravastatin as first-choice drugs compared to 36.5% in the case of the moderators. The prescribing of statins with fibrates or macrolides in

The relative contribution of behavioural, psychosocial and HCV disease factors to reduction in HCV health-related quality of life is not well understood. The objectives of the present study were to compare standardized health-related quality of life scores between Canadian HCV patients and age-matched Canadian and American norms, and to examine the relative contribution of biopsychosocial variables (ie, cigarette smoking, alcohol intake and depression to health-related quality of life scores among Canadian HCV patients.

  9. The dynamic interaction of quality and efficiency in the emergency department: Squaring the circle?

    2010-02-01

    This paper examines the relationship between clinical quality and organizational efficiency in emergency departments (EDs). Previous studies have often emphasized the incompatibility of quality and efficiency, or have neglected to account for their inter-relationships. Policy perspectives reflect normative prescriptions for throughput and reduced waiting times which do not always align with clinicians' foci or day-to-day practices. According to Merton's (1957) theory of "value-assimilation", medical students, for instance, are socialized to reconcile seemingly contradictory values. We aimed to explore ethnographically the possibility of the dynamic interactions of quality and efficiency in clinical practice. This study drew on empirical data from ethnographic field work, conducted over one year, including 234 hours of semi-structured observations and 56 semi-structured field interviews in the EDs of two tertiary-referral hospitals in Sydney, Australia. We found that seniority and experience of emergency clinicians intersect with the functions of role-modeling, performance management, and formal and informal learning, to facilitate the care of multiple patients as they progress through the ED. These practices fundamentally embed quality in the ED's enactment of efficiency. The relationship between clinical quality and organizational efficiency can be understood through a sociological lens that highlights the roles of interdependent clinicians in a clinical pecking order, working to provide care, and balancing the two. The paper is novel in expanding "value-assimilation" into the clinical domain, and strives to reconcile policy with everyday practice in emergency settings. It moves the debate about quality versus efficiency to one that emphasizes interdependence. Crown Copyright 2009. Published by Elsevier Ltd. All rights reserved.

    To harmonize good production practices (GPP) for dairy producers in Canada, the Canadian dairy industry has developed and is implementing a program called Canadian Quality Milk (CQM). A postal questionnaire was administered to all Canadian dairy producers enrolled in dairy herd-improvement organizations in 2008 (n=10,474) to investigate their attitudes towards the program and to establish baseline information on their use of GPP. The response percentage was 20.9% (2185/10,474). Two-thirds of producers (67.6%) reported participation in CQM and 61.4% of these indicated that the requirements were easy to implement. Most producers (85.0%) reported the use of cats as a pest-control method in their barns. For dead-livestock disposal, 65.0% and 38.0% indicated use of a collection service and burial, respectively. Nearly 40.0% of respondents indicated that they purchase replacement cattle, and somatic cell-count score was the main health indicator considered before purchase. Over 70% of producers reported that they clean and disinfect maternity, calf and weaned-calf pens, while only 34.1% and 53.1% reported that they provide visitors and employees, respectively, with clean clothes and boots. Through latent-class analysis, five groups (classes) of producers with distinctive patterns of reported use of GPP were identified. These were labelled as "minimal", "sanitation-only", "employee-visitor hygiene", "typical" and "ideal" user groups, with 11.1%, 23.8%, 20.2%, 37.1% and 7.7% of respondents, respectively. Respondents in the "ideal users" group had a higher probability of reporting the use of each GPP and were more likely to have completed an educational course in food safety compared to respondents in each other group. They were also more likely to have a herd size in the uppermost quartile (>65 cows) and report participation in CQM compared to each other group except the "employee-visitor hygiene users". The greatest differences were observed when compared to the "minimal

    Six pioneer physicians-pharmacists quality circles (PPQCs) located in the Swiss canton of Fribourg (administratively corresponding to a state in the US) were under the responsibility of 6 trained community pharmacists moderating the prescribing process of 24 general practitioners (GPs). PPQCs are based on a multifaceted collaborative process mediated by community pharmacists for improving compliance with clinical guidelines within GPs' prescribing practices. To assess, over a 9-year period (1999-2007), the cost-containment impact of the PPQCs. The key elements of PPQCs are a structured continuous quality improvement and education process; local networking; feedback of comparative and detailed data regarding costs, drug choice, and frequency of prescribed drugs; and structured independent literature review for interdisciplinary continuing education. The data are issued from the community pharmacy invoices to the health insurance companies. The study analyzed the cost-containment impact of the PPQCs in comparison with GPs working in similar conditions of care without particular collaboration with pharmacists, the percentage of generic prescriptions for specific cardiovascular drug classes, and the percentage of drug costs or units prescribed for specific cardiovascular drugs. For the 9-year period, there was a 42% decrease in the drug costs in the PPQC group as compared to the control group, representing a $225,000 (USD) savings per GP only in 2007. These results are explained by better compliance with clinical and pharmacovigilance guidelines, larger distribution of generic drugs, a more balanced attitude toward marketing strategies, and interdisciplinary continuing education on the rational use of drugs. The PPQC work process has yielded sustainable results, such as significant cost savings, higher penetration of generics and reflection on patient safety, and the place of "new" drugs in therapy. The PPQCs may also constitute a solid basis for implementing more

    Peer review groups (PRGs) and quality circles (QCs) commenced in The Netherlands and have grown to become an important method of quality improvement in primary care in several other European countries. Our aim was to provide an overview of QC/PRG activities and exemplary programmes in European countries. A survey was performed in three consecutive steps by EQuiP (European Working Party on Quality in Family Practice), which is a representative association of experts from 26 European countries. The national representatives initially completed a structured questionnaire documenting the number and objectives of QCs/PRGs, sources of support and special programmes in their countries (step 1). In step 2, these sources were used to extend and validate the expert statements. Step 3 studied paradigmatic initiatives in depth. Step 1 took place in 2000; the response rate was 100% (26 countries). QCs/PRGs were very active in 10 countries; 16 countries showed little or no activity. Participation ranged from quality of care.

    Full Text Available Abstract Background In Canada, the incidence of Fetal Alcohol Spectrum Disorder (FASD has been estimated to be 1 in 100 live births. Caused by prenatal exposure to alcohol, FASD is the leading cause of neuro-developmental disabilities among Canadian children, and youth. Objective: To measure the health-related quality of life (HRQL of Canadian children and youth diagnosed with FASD. Methods A prospective cross-sectional study design was used. One-hundred and twenty-six (126 children and youth diagnosed with FASD, aged 8 to 21 years, living in urban and rural communities throughout Canada participated in the study. Participants completed the Health Utilities Index Mark 3 (HUI3. HUI3 measures eight health attributes: vision, hearing, speech, ambulation, dexterity, emotion, cognition, and pain. Utilities were used to measure a single cardinal value between 0 and 1.0 (0 = all-worst health state; 1 = perfect health to reflect the global HRQL for that child. Mean HRQL scores and range of scores of children and youth with FASD were calculated. A one-sample t-test was used to compare mean HRQL scores of children and youth with FASD to those from the Canadian population. Results Mean HRQL score of children and youth with FASD was 0.47 (95% CI: 0.42 to 0.52 as compared to a mean score of 0.93 (95% CI: 0.92 to 0.94 in those from the general Canadian population (p Conclusion Children and youth with FASD have significantly lower HRQL than children and youth from the general Canadian population. This finding has significant implications for practice, policy development, and research.

    This study discussed the bitumen upgrading process and bitumen properties. Recent research on bitumen upgrading was reviewed, and methods of processing bitumens in conventional oil refineries were discussed. The study determined that bitumens contain large amounts of sulfur, aromatics, carbon residues, asphaltenes, and nitrogen, the majority of which is located in the last 15 per cent of the bitumen, or end cut. New upgrading processes used by Syncrude included an extraction and froth treatment plant, a diluent recovery unit (DRU) and vacuum distillation unit (VDU). Liquid products from the hydrotreaters were blended as synthetic crude oil (SCO) and shipped to refineries. The study also reviewed hydrotreating methods for gas oils; hydrocracking technologies; olefins and diolefins hydrogenation of coker naphtha; and aromatics hydrogenation. Tools to monitor the performance of commercial hydrotreaters were discussed, and the kinetics of aromatics hydrogenation were reviewed. Details of molecular structure analyses were presented. It was concluded that hydrotreating is an effective means of producing good quality SCO. 53 refs., 6 tabs., 10 figs.

    The Canadian Immunohistochemistry Quality Control program monitors clinical laboratory performance for estrogen receptor and progesterone receptor tests used in breast cancer treatment management in Canada. Current methods assess sensitivity and specificity at each time point, compared with a reference standard. We investigate alternative performance analysis methods to enhance the quality assessment. We used 3 methods of analysis: meta-analysis of sensitivity and specificity of each laboratory across all time points; sensitivity and specificity at each time point for each laboratory; and fitting models for repeated measurements to examine differences between laboratories adjusted by test and time point. Results show 88 laboratories participated in quality control at up to 13 time points using typically 37 to 54 histology samples. In meta-analysis across all time points no laboratories have sensitivity or specificity below 80%. Current methods, presenting sensitivity and specificity separately for each run, result in wide 95% confidence intervals, typically spanning 15% to 30%. Models of a single diagnostic outcome demonstrated that 82% to 100% of laboratories had no difference to reference standard for estrogen receptor and 75% to 100% for progesterone receptor, with the exception of 1 progesterone receptor run. Laboratories with significant differences to reference standard identified with Generalized Estimating Equation modeling also have reduced performance by meta-analysis across all time points. The Canadian Immunohistochemistry Quality Control program has a good design, and with this modeling approach has sufficient precision to measure performance at each time point and allow laboratories with a significantly lower performance to be targeted for advice.

    Saskatchewan has embarked on a journey to transform the quality of its healthcare. Through our experiences, we have learned many lessons that could be useful to the development of a pan-Canadian system of measurement aimed at bettering care. However, measurement in isolation is insufficient to achieve improved healthcare. The system needs to be linked to a common improvement agenda. Creating a systematic approach to improvement is only possible through developing the capacities of leaders and front-line staff, by alignment through a common purpose, by focusing on value from the perspective of the customer and by creating measures backed by best practice that are transparent and accountable.

    Canadian healthcare is under increased scrutiny to improve quality and performance, and for good reason. The proliferation of provincial-level quality councils underscores the urgency to establish an aligned national quality agenda. Patient safety has long been held as a critical element of a high-quality healthcare system; with the inexorable growth in spending, efficiency has more recently been introduced. Efficiency and quality are both factors in Ontario's Excellent Care for All legislation introduced in June of 2010, and Quebec's l'Institut national d'excellence en santé et en services sociaux (INESSS) arising from the Castonguay report. These associations of quality and efficiency are also echoed in the US, Australian and UK public debates. The development of a quality agenda has concurrently precipitated discussion regarding responsibility for quality, particularly but not exclusively with the emergence of quality issues in the technical and interpretive pathology arena. The discussion and debate on responsibility have become preoccupations at the national, provincial, institutional and individual profession levels.

    Full Text Available Background and objectives: A shift to holding individual physicians accountable for patient outcomes, rather than facilities, is intuitively attractive to policy makers and to the public. We were interested in nephrologists’ attitudes to, and awareness of, quality metrics and how nephrologists would view a potential switch from the current model of facility-based quality measurement and reporting to publically available reports at the individual physician level. Design, setting, participants, and measurements: The study was conducted using a web-based survey instrument (Online Appendix 1. The survey was initially pilot tested on a group of 8 nephrologists from across Canada. The survey was then finalized and e-mailed to 330 nephrologists through the Canadian Society of Nephrology (CSN e-mail distribution list. The 127 respondents were 80% university based, and 33% were medical/dialysis directors. Results: The response rate was 43%. Results demonstrate that 89% of Canadian nephrologists are engaged in efforts to improve the quality of patient care. A minority of those surveyed (29% had training in quality improvement. They feel accountable for this and would welcome the inclusion of patient-centered metrics of care quality. Support for public reporting as an effective strategy on an individual nephrologist level was 30%. Conclusions: Support for public reporting of individual nephrologist performance was low. The care of nephrology patients will be best served by the continued development of a critical mass of physicians trained in patient safety and quality improvement, by focusing on patient-centered metrics of care delivery, and by validating that all proposed new methods are shown to improve patient care and outcomes.

    To examine the association between diet quality and feelings of worry, sadness or unhappiness in Canadian children. Responses to the Harvard Food Frequency Questionnaire of 6,528 grade 5 students were used to calculate a composite score of diet quality, and its components: variety, adequacy, moderation and balance. Responses to the question on "feelings of worry, sadness or unhappiness" from the EuroQoL 5 Dimension questions for Youth (EQ-5D-Y), a validated Health Related Quality of Life questionnaire, constitute the outcome of interest. Multilevel logistic regression methods were used to examine the association between diet quality and feelings of worry, sadness or unhappiness. All analyses were adjusted for gender, household income, parental education, energy intake, weight status, physical activity level, geographic area and year of data collection. Diet quality was inversely associated with children's feelings of worried, sad or unhappy (Odds ratio (95% confidence interval): 0.90 (0.85-0.97)). Dietary variety and dietary adequacy were also statistically significantly associated with lower odds of feeling worried, sad or unhappy. When the results were stratified by gender, the effect of diet on feeling worried, sad or unhappy was more pronounced in girls than boys. These findings suggest that diet quality plays a role in feelings of worry, sadness or unhappiness and complement other studies that have suggested the link between diet and mental health. We recommend consideration of diet quality in public health strategies that aim to reduce the burden of poor mental health in children and youth.

    There is a lack of validated quality metrics to evaluate the care of patients receiving surgery for renal cell carcinoma (RCC). To address this, the Kidney Cancer Research Network of Canada defined a list of quality indicators (QI) to assess hospital-level performance. We have case-mix adjusted these QIs to benchmark RCC surgical care at Canadian academic centres. The Canadian Kidney Cancer information system (CKCis) was used to measure six QIs: laparoscopic approach proportion (LA), partial nephrectomy proportion (PN), partial nephrectomy in patients with chronic kidney disease (CKDPN), positive margin rate (PMR), partial nephrectomy complication rate (PNCx), and warm ischemia time (WIT). To benchmark performance, indirect standardization (observed-to-expected ratio) methodology was employed using multivariate regression models. Multivariate models for LA, PN, and CKDPN demonstrated good discrimination and were used for benchmarking. National averages of 74% (70-78%), 73% (70-75%), and 70% (67-74%) for the LA, PN, and CKDPN QIs, respectively, were determined and used to benchmark individual hospital performance. Overall, three (23%), two (15%), and two (15%) hospitals performed below expected for LA, PN, and CKDPN, respectively. Hospital identity was an independent predictor of LA, PN, and CKDPN (p<0.001). Significant variability between CKCis hospitals for three RCC surgical QIs exists. Using the CKCis infrastructure may provide a framework for institution-level audit feedback for quality improvement. Greater CKCis capture rates and further data supporting the construct validity of these QIs are required to extend the use of this dataset to real-world quality initiatives.

    A case-study approach was used to identify opportunities and challenges to the implementation of the Three Rs in vaccine testing in Canada. Data was obtained through interviews with 16 Canadian stakeholders involved in the production, testing and evaluation of vaccines. Participants identified inconsistent regulatory testing requirements, the lack of biological functionality of some in vitro methods, the benchmarking of in vitro against in vivo assays, and high caution towards method changes as major challenges to implementation. Opportunities to implementation were identified as the desire for and steps taken towards harmonization of test methods between countries, collaborations on new method development, the poor performance of traditional animal methods, the domino effect of one regulatory authority accepting a method after another, and stakeholder concerns for the ethical care and use of animals used in vaccine testing. These results suggest that industry and the Canadian government are open to implementing the Three Rs in vaccine quality control, but methods adopted must be reliable and biologically relevant. Improving the harmonization of regulatory requirements will assist in furthering the implementation of alternative methods. Copyright © 2012 Elsevier Inc. All rights reserved.

  6. AEROCAN, the Canadian sub-network of AERONET: Aerosol monitoring and air quality applications

    Previous studies have demonstrated the utility of AERONET (Aerosol Robotic Network) aerosol optical depth (AOD) data for monitoring the spatial variability of particulate matter (PM) in relatively polluted regions of the globe. AEROCAN, a Canadian sub-network of AERONET, was established 20 years ago and currently consists of twenty sites across the country. In this study, we examine whether the AEROCAN sunphotometer data provide evidence of anthropogenic contributions to ambient particulate matter concentrations in relatively clean Canadian locations. The similar weekly cycle of AOD and PM2.5 over Toronto provides insight into the impact of local pollution on observed AODs. High temporal correlations (up to r = 0.78) between daily mean AOD (or its fine-mode component) and PM2.5 are found at southern Ontario AEROCAN sites during May-August, implying that the variability in the aerosol load resides primarily in the boundary layer and that sunphotometers capture day-to-day PM2.5 variations at moderately polluted sites. The sensitivity of AEROCAN AOD data to anthropogenic surface-level aerosol enhancements is demonstrated using boundary-layer wind information for sites near sources of aerosol or its precursors. An advantage of AEROCAN relative to the Canadian in-situ National Air Pollution Surveillance (NAPS) network is the ability to detect free tropospheric aerosol enhancements, which can be large in the case of lofted forest fire smoke or desert dust. These aerosol plumes eventually descend to the surface, sometimes in populated areas, exacerbating air quality. In cases of large AOD (≥0.4), AEROCAN data are also useful in characterizing the aerosol type. The AEROCAN network includes three sites in the high Arctic, a region not sampled by the NAPS PM2.5 monitoring network. These polar sites show the importance of long-range transport and meteorology in the Arctic haze phenomenon. Also, AEROCAN sunphotometers are, by design and due to regular maintenance, the most

    Hereditary angioedema (HAE) is a rare but serious condition characterized by recurrent spontaneous attacks of angioedema affecting superficial tissues of upper respiratory and gastrointestinal tracts. The potentially fatal and disfiguring nature of HAE impacts the health-related quality of life (HRQoL) of patients with this condition. To assess the health-related quality of life of Canadian patients with HAE using the 36-item Short-Form Health Survey (SF-36v2). Twenty-one patients living in Canada over age 18 with known diagnosis of hereditary angioedema due to C1-INH deficiency (HAE), completed the SF-36v2 (generic HRQoL questionnaire). Results were compared to Canadian normative data by converting the SF-36 scores into z scores. The SF-36v2 showed a significant reduction in general health (p = 0.0063) in patients with HAE when compared with healthy Canadians. Percentage of patients with z scores below 0.8 (large effect) was 47.6% for general health subscale, 33.3% for bodily pain and vitality subscales and 28.6% for physical component scores. Mean scores of eight dimensions ranged from 57.7 to 88.9. Mean Physical and mental component scores were 49.1 and 50.4. Internal consistency of evaluation was demonstrated by Cronbach's alpha value above 0.7 for all scales. General perception of health was significantly different in these patients, compared to Canadian normative data. This study of Canadian patients with HAE shows that General Health is most frequently affected followed by Bodily Pain and Vitality, as measured by SF-36v2. The SF-36v2 offers valuable insight to assess quality of life in patients with HAE, however a larger number of Canadian patients and specific tools for assessment are needed for better evaluation.

    Thus far important findings regarding the dementia syndrome have been implemented into patients' medical care only inadequately. A professional training accounting for both, general practitioners' (GP) needs and learning preferences as well as care-relevant aspects could be a major step towards improving medical care. In the WIDA-study, entitled "Knowledge translation on dementia in general practice" two different training concepts are developed, implemented and evaluated. Both concepts are building on an evidence-based, GP-related dementia guideline and communicate the guideline's essential insights. Both development and implementation emphasize a procedure that is well-accepted in practice and, thus, can achieve a high degree of external validity. This is particularly guaranteed through the preparation of training material and the fact that general practitioners' quality circles (QC) are addressed. The evaluation of the two training concepts is carried out by comparing two groups of GPs to which several quality circles have been randomly assigned. The primary outcome is the GPs' knowledge gain. Secondary outcomes are designed to indicate the training's potential effects on the GPs' practical actions. In the first training concept (study arm A) GPs participate in a structured case discussion prepared for by internet-based learning material ("blended-learning" approach). The second training concept (study arm B) relies on frontal medical training in the form of a slide presentation and follow-up discussion ("classical" approach). This paper presents the outline of a cluster-randomized trial which has been peer reviewed and support by a national funding organization--Federal Ministry of Education and Research (BMBF)--and is approved by an ethics commission. The data collection has started in August 2006 and the results will be published independently of the study's outcome. Current Controlled Trials [ISRCTN36550981].

    Results from the first assessment of air quality over the Canadian oil sands-one of the largest industrial undertakings in human history-using satellite remote sensing observations of two pollutants, nitrogen dioxide (NO2) and sulfur dioxide (SO2), are presented. High-resolution maps were created that revealed distinct enhancements in both species over an area (roughly 30 km × 50 km) of intensive surface mining at scales of a few kilometers. The magnitude of these enhancements, quantified in terms of total mass, are comparable to the largest seen in Canada from individual sources. The rate of increase in NO2 between 2005 and 2010 was assessed at 10.4 ± 3.5%/year and resulted from increases both in local values as well as the spatial extent of the enhancement. This is broadly consistent with both surface-measurement trends and increases in annual bitumen production. An increase in SO2 was also found, but given larger uncertainties, it is not statistically significant.

    Dark circles refer to a symptom that present darkness under the eyes. Because of improvement in the quality of life, the dark circles have been recognized as one of major cosmetic concerns. However, it is not easy to classify the dark circles because they have various causes. To select suitable instruments and detailed evaluation items, the dark circles were classified according to the causes through visual assessment, Wood's lamp test, and medical history survey for 100 subjects with dark circles. After the classification, were newly recruited for instrument conformity assessment. Through this, suitable instruments for dark circle evaluation were selected. We performed a randomized clinical trial for dark circles, a placebo-controlled double-blind study, using effective parameters of the instruments selected from the preliminary test. Dark circles of vascular type (35%) and mixed type (54%), a combination of pigmented and vascular types, were the most common. Twenty four subjects with the mixed type dark circles applied the test product (Vitamin C 3%, Vitamin A 0.1%, Vitamin E 0.5%) and placebo on randomized split-face for 8 weeks. The effective parameters (L*, a, M.I., E.I., quasi L*, quasi a* and dermal thickness) were measured during the study period. Result showed that the L* value of Chromameter(®) , Melanin index (M.I.) of Mexameter(®) and quasi L* value obtained by image analysis improved with statistical significance after applying the test product compared with the placebo product. We classified the dark circles according to the causes of the dark circles and verified the reliability of the parameter obtained by the instrument conformity assessment used in this study through the efficacy evaluation. Also based on this study, we were to suggest newly established methods which can be applied to the evaluation of efficacy of functional cosmetics for dark circles. © 2015 John Wiley & Sons A/S.

    There is limited research on the dietary behaviours of Canadian children at school, including where students obtain food from during school hours or whether lunch-time food source influences diet quality. Nationally representative cross-sectional data from 24-h dietary recalls were analysed from the 2004 Canadian Community Health Survey (n = 4589). Dietary outcomes included school hour and school day dietary intakes and School Healthy Eating Index (S-HEI) scores. Survey-weighted covariate-adjusted linear regression models examined differences in dietary outcomes across lunch-time food source groups. The majority of children (72.8%) reported bringing lunch from home, whereas fewer students obtained lunch from off-campus locations (11.6%), schools (9.6%) or skipped lunch (5.9%). Compared to off-campus lunches, home-packed lunches were significantly higher in fibre, vitamins A, D and C, thiamin, magnesium, iron, grains, vegetables and fruit, but lower in total calories, fat and calories from minimally nutritious foods. Average school hour diet quality required improvement for all age groups, although S-HEI scores did not differ significantly by lunch-time food source among 6-8-year-old children. However, for children age 9-17 years, bringing a home-packed lunch was associated with significantly higher S-HEI scores compared to students obtaining lunch from off-campus locations. After adjusting for age and sex, lunch-time food source was also significantly associated with whole day dietary quality. Although the nutritional quality of off-campus lunches was lower than home-packed lunches, the quality of foods was suboptimal, regardless of food source. Strategies are needed to enhance access to nutritious foods on campus and improve the nutritional quality of packed lunches, which supply the majority of lunch-time foods consumed by Canadian children. © 2017 The British Dietetic Association Ltd.

    We examined the impact of socioeconomic and cultural factors on dietary quality in adult Inuit living in the Canadian Arctic. Interviews and a 24-h dietary recall were administered to 805 men and 1292 women from Inuit regions in the Canadian Arctic. We examined the effect of age, sex, education, income, employment, and cultural variables on respondents' energy, macronutrient intake, sodium/potassium ratio, and healthy eating index. Logistic regression was used to assess the impact of socioeconomic status (SES) on diet quality indicators. Age was positively associated with traditional food (TF) consumption and greater energy from protein but negatively associated with total energy and fibre intake. Associations between SES and diet quality differed considerably between men and women and there was considerable regional variability in diet quality measures. Age and cultural variables were significant predictors of diet quality in logistic regression. Increased age and use of the Inuit language in the home were the most significant predictors of TF consumption. Our findings are consistent with studies reporting a nutrition transition in circumpolar Inuit. We found considerable variability in diet quality and complex interaction between SES and cultural variables producing mixed effects that differ by age and gender.

    This study presents effects of adding Circle of Security-Parenting (COS-P) to an already established comprehensive therapeutic model for early parent-child intervention in three Swedish infant mental health (IMH) clinics. Parents' internal representations and quality of parent-infant interaction were studied in a clinical sample comprised of 52 parent-infant dyads randomly allocated to two comparable groups. One group consisted of 28 dyads receiving treatment as usual (TAU) supplemented with COS-P in a small group format, and another group of 24 dyads receiving TAU only. Assessments were made at baseline (T1), 6 months after inclusion (T2) and 12 months after inclusion (T3). Changes over time were explored in 42 dyads. In the COS-P group, the proportion of balanced representations, as assessed with Working Model of the Child Interview (WMCI), significantly increased between T1 and T3. Further, the proportion of emotionally available interactions, as assessed with Emotional Availability scales (EA), significantly increased over time in the COS-P group. Improvements in the TAU-group were close to significant. Limitations of the study are mainly related to the small sample size. Strength is the real world character of the study, where COS-P was implemented in a clinical context not otherwise adapted to research. We conclude by discussing the value of supplementing TAU with COS-P in IMH treatment. © 2017 The Authors.

Patients and Methods. 145 patients with DME were followed for 6 months with monthly telephone interviews and medical chart reviews at months 0, 3, and 6. Visual acuity in the worst-seeing eye was assessed at months 0 and 6. DME-related healthcare costs were determined over 6 months, and vision-related (National Eye Institute Visual Functioning Questionnaire and generic (EQ-5D quality of life was assessed at months 0, 3, and 6. Results. Mean age of patients was 63.7 years: 52% were male and 72% had bilateral DME. At baseline, visual acuity was categorized as normal/mild loss for 63.4% of patients, moderate loss for 10.4%, and severe loss/nearly blind for 26.2%. Mean 6-month DME-related costs/patient were as follows: all patients (n=135, $2,092; normal/mild loss (n=88, $1,776; moderate loss (n=13, $1,845; and severe loss/nearly blind (n=34, $3,007. Composite scores for vision-related quality of life declined with increasing visual acuity loss; generic quality of life scores were highest for moderate loss and lowest for severe loss/nearly blind. Conclusions. DME-related costs in the Canadian healthcare system are substantial. Costs increased and vision-related quality of life declined with increasing visual acuity severity.

    Quality circles (QC) are viewed as one of the most important tools of quality improvement and continuing education in ambulatory care. Yet, little is known about the quality of QC work. From 1995 to 2007, an external assessment of QC work took place at four regional Associations of Statutory Health Insurance (SHI) Physicians. After each meeting, QC leaders completed questionnaires. This basic documentation focused on important features of QC work--continuity, topics, methods, results and satisfaction. 28,800 meetings in 1,640 quality circles were documented, and 27,255 documents from 1,241 groups analysed. Continuity was high over long periods, and medical topics were dealt with in more than 80% of the time. The use of appropriate methods, however, have room for improvement. Participants were very satisfied. For the first time the quality of QC structures, processes and results was assessed in Germany using a broad dataset. The working principles of QC appear to be well-established. Using the basic documentation practical recommendations are made to improve the quality of QC.

    Full Text Available Abstract Background Health Canada’s Surveillance Tool (HCST Tier System was developed in 2014 with the aim of assessing the adherence of dietary intakes with Eating Well with Canada’s Food Guide (EWCFG. HCST uses a Tier system to categorize all foods into one of four Tiers based on thresholds for total fat, saturated fat, sodium, and sugar, with Tier 4 reflecting the unhealthiest and Tier 1 the healthiest foods. This study presents the first application of the HCST to examine (i the dietary patterns of Canadian children, and (ii the applicability and relevance of HCST as a measure of diet quality. Methods Data were from the nationally-representative, cross-sectional Canadian Community Health Survey 2.2. A total of 13,749 participants aged 2–18 years who had complete lifestyle and 24-hour dietary recall data were examined. Results Dietary patterns of Canadian children and adolescents demonstrated a high prevalence of Tier 4 foods within the sub-groups of processed meats and potatoes. On average, 23–31 % of daily calories were derived from “other” foods and beverages not recommended in EWCFG. However, the majority of food choices fell within the Tier 2 and 3 classifications due to lenient criteria used by the HCST for classifying foods. Adherence to the recommendations presented in the HCST was associated with closer compliance to meeting nutrient Dietary Reference Intake recommendations, however it did not relate to reduced obesity as assessed by body mass index (p > 0.05. Conclusions EWCFG recommendations are currently not being met by most children and adolescents. Future nutrient profiling systems need to incorporate both positive and negative nutrients and an overall score. In addition, a wider range of nutrient thresholds should be considered for HCST to better capture product differences, prevent categorization of most foods as Tiers 2–3 and provide incentives for product reformulation.

    2013-01-01

    A society that values mental health and helps people live enjoyable and meaningful lives is a clear aspiration echoed throughout our Canadian health care system. The Mental Health Commission of Canada has put forth a framework for a mental health strategy with goals that reflect the virtue of optimal mental health for all Canadians (Mental Health Commission Canada, 2009).

    A society that values mental health and helps people live enjoyable and meaningful lives is a clear aspiration echoed throughout our Canadian health care system. The Mental Health Commission of Canada has put forth a framework for a mental health strategy with goals that reflect the virtue of optimal mental health for all Canadians (Mental Health Commission Canada, 2009). Canadian nurses, the largest group of health care workers, have a vital role in achieving these goals. In Canada, two-thirds of those who experience mental health problems do not receive mental health services (Statistics Canada, 2003). Through a gendered, critical, and sociological perspective the goal of this paper is to further understand how the past has shaped the present state of psychiatric mental health nursing (PMHN).

    Full Text Available The 2014 Health Canada Surveillance Tool (HCST was developed to assess adherence of dietary intakes with Canada’s Food Guide. HCST classifies foods into one of four Tiers based on thresholds for sodium, total fat, saturated fat and sugar, with Tier 1 representing the healthiest and Tier 4 foods being the unhealthiest. This study presents the first application of HCST to assess (a dietary patterns of Canadians; and (b applicability of this tool as a measure of diet quality among 19,912 adult participants of Canadian Community Health Survey 2.2. Findings indicated that even though most of processed meats and potatoes were Tier 4, the majority of reported foods in general were categorized as Tiers 2 and 3 due to the adjustable lenient criteria used in HCST. Moving from the 1st to the 4th quartile of Tier 4 and “other” foods/beverages, there was a significant trend towards increased calories (1876 kcal vs. 2290 kcal and “harmful” nutrients (e.g., sodium as well as decreased “beneficial” nutrients. Compliance with the HCST was not associated with lower body mass index. Future nutrient profiling systems need to incorporate both “positive” and “negative” nutrients, an overall score and a wider range of nutrient thresholds to better capture food product differences.

    Full Text Available Given a bounded sequence of integers {d0,d1,d2,…}, 6≤dn≤M, there is an associated abstract triangulation created by building up layers of vertices so that vertices on the nth layer have degree dn. This triangulation can be realized via a circle packing which fills either the Euclidean or the hyperbolic plane. We give necessary and sufficient conditions to determine the type of the packing given the defining sequence {dn}.

    Successful guideline implementation requires that the authors get feedback from target groups on the general acceptance of a guideline and the barriers to its implementation. The Guideline Group of General Practitioners (GPs) in Hesse continually surveyed participants of quality circles on pharmacotherapy who discussed these GP specific guidelines together with an analysis of their prescription behaviour. Written survey of six general practice guidelines conducted among the members of quality circles in Hesse during 2006 and 2007. The response rate ranged from 69% (n=268; guideline on 'GP Communication Skills') and 80% (n=374; Guideline on 'Chronic Heart Failure'). The questionnaire focused on both general acceptance and the relevance and practicability of individual recommendations. With pharmacotherapeutic guidelines, between 75% (guideline for dyslipidaemia) and 86% (guideline for stable angina) would be recommended by the respondent GPs to colleagues. High practice relevance was attributed to the communication skills guideline by 70% of the GPs, but only about 50% would recommend it. Three quarters of the GP rated 18 out of 22 selected recommendations as being relevant to therapeutic quality assurance, and 11 of these recommendations as being practicable. Non-medical procedures requiring communication resources and time input as well as motivated patients were more often assessed as being more difficult to implement. A written survey is a suitable tool for gaining insight into the acceptance of diagnostic and therapeutic strategies and for investigating reasons for the refusal of or the barriers to implementation. Recommendations that are poorly accepted and less likely to be implemented as well as possible barriers should be discussed within the guideline group and during circle sessions in order to modify the recommendation and/or develop aids to assist with its transfer into everyday practice.

    This article presents the first comprehensive review and analysis of the uptake of the Canadian Drinking Water Quality Guidelines (CDWQG) across Canada’s 13 provinces and territories. This review is significant given that Canada’s approach to drinking water governance is: (i) highly decentralized and (ii) discretionary. Canada is (along with Australia) only one of two Organization for Economic Cooperation and Development (OECD) member states that does not comply with the World Health Organization’s (WHO) recommendation that all countries have national, legally binding drinking water quality standards. Our review identifies key differences in the regulatory approaches to drinking water quality across Canada’s 13 jurisdictions. Only 16 of the 94 CDWQG are consistently applied across all 13 jurisdictions; five jurisdictions use voluntary guidelines, whereas eight use mandatory standards. The analysis explores three questions of central importance for water managers and public health officials: (i) should standards be uniform or variable; (ii) should compliance be voluntary or legally binding; and (iii) should regulation and oversight be harmonized or delegated? We conclude with recommendations for further research, with particular reference to the relevance of our findings given the high degree of variability in drinking water management and oversight capacity between urban and rural areas in Canada.

    Thomas Willis (1621-1675) grew up in Wiltshire and studied medicine in Oxford, at a time when the city was besieged and then occupied by Parliamentarian troops. He started his career as a country doctor while concurrently taking part in informal gatherings with other scientists (William Petty, Christopher Wren and, later on, Robert Hooke, Richard Lower and Robert Boyle). They performed physical and chemical experiments and carried out a variety of tests on animals. After the restoration of the monarchy in 1660 Willis combined his practice with academic teaching. From then on he focused his studies on the structure and function of the brain, dissecting brains after removal from the skull and fixation in 'spirit of wine'. In his 'Cerebri anatome' of 1664, illustrated by Wren, he drew attention to the arterial circle at the base of the brain, including its physiological advantages. This arterial circle had been incompletely described by others in the past and fully, but only in writing, by Wepfer in 1658.

    [figure removed for brevity, see original site] Circle of Ashes This plot tells astronomers that a pulsar, the remnant of a stellar explosion, is surrounded by a disk of its own ashes. The disk, revealed by the two data points at the far right from NASA's Spitzer Space Telescope, is the first ever found around a pulsar. Astronomers believe planets might rise up out of these stellar ashes. The data in this plot, or spectrum, were taken by ground-based telescopes and Spitzer. They show that light from around the pulsar can be divided into two categories: direct light from the pulsar, and light from the dusty disk swirling around the pulsar. This excess light was detected by Spitzer's infrared array camera. Dust gives off more infrared light than the pulsar because it's cooler. The pulsar, called 4U 0142+61, was once a massive star, until about 100,000 years ago, when it blew up in a supernova explosion and scattered dusty debris into space. Some of that debris was captured into what astronomers refer to as a 'fallback disk,' now circling the leftover stellar core, or pulsar. The disk resembles protoplanetary disks around young stars, out of which planets are thought to be born. The data have been corrected to remove the effects of light scattering from dust that lies between Earth and the pulsar. The ground-based data is from the Keck I telescope atop Mauna Kea, Hawaii.

  1. Recumbent Stone Circles

    Science.gov (United States)

    Ruggles, Clive L. N.

    During the 1970s and early 1980s, British archaeoastronomers were striving to bridge the interpretative gulf between the "megalithic observatories" of Alexander Thom and an archaeological mainstream that, generally speaking, was hostile to any mention of astronomy in relation to the megalithic monuments of Neolithic and Early Bronze Age Britain. The Scottish recumbent stone circles (RSCs) came to represent an example where sounder methodology could overcome many of the data selection issues that had beset earlier studies and, with due restraint, produce credible interpretations. Systematic studies of their orientations consistently concluded that the RSCs had a strong lunar connection, and it was widely envisaged that they were the setting for ceremonies associated with the appearance of the moon over the recumbent stone. Other evidence such as the presence of white quartz and the spatial distribution of cupmarks appeared to back up this conclusion. New archaeological investigations since 1999 have challenged and modified these conclusions, confirming in particular that the circles were built to enclose cairns rather than to demarcate open spaces. Yet the restricted pattern of orientations of these structures could only have been achieved by reference to the basic diurnal motions of the skies, and orientation in relation to simple observations of the midsummer moon remains the most likely reading of the alignment evidence taken as a whole. On the other hand, a consideration of the broader context, which includes the nearby Clava cairns, highlights instead the symbolic importance of the sun.

To translate and adapt CCHS questionnaire to be used by the Spanish-speaking population since it is a specific questionnaire for celiac disease. To adapt the CCHS, which consists of 76 items divided into 11 different sections, was performed using translation-back-translation method and after being reviewed and agreed proceeded to conduct a pilot test with 25 people with celiac disease, individually and a member of the research group to assess the understanding of the items and their sections. The contributions were introduced, setting the final questionnaire. The greatest difficulty in the translation in question occurred where there were active and trade names of drugs, opting for it to those marketed nationwide. On the other hand, for the pilot study questionnaire showed a good value of the naturalness of understanding with values between 8.4 and 10.0. The specific tool CHCS allow the use of a questionnaire that can be used by the Spanish speaking population studies, clinical trials or health professional practice everyday, allowing a better understanding of the health of celiacs.

    This paper reports on a survey of medical physicists who write and use in-house written software as part of their professional work. The goal of the survey was to assess the extent of in-house software usage and the desire or need for related software quality guidelines. The survey contained eight multiple-choice questions, a ranking question, and seven free text questions. The survey was sent to medical physicists associated with cancer centers across Canada. The respondents to the survey expressed interest in having guidelines to help them in their software-related work, but also demonstrated extensive skills in the area of testing, safety, and communication. These existing skills form a basis for medical physicists to establish a set of software quality guidelines.

    Home care is becoming an increasingly vital sector in the health care system yet very little is known about the characteristics of home care clients and the quality of care provided in Canada. We describe these clients and evaluate home care quality indicator rates in two regions. A cross-sectional analysis of assessments completed for older (age 65+) home care clients in both Ontario (n = 102,504) and the Winnipeg Regional Health Authority (n = 9,250) of Manitoba, using the Resident Assessment Instrument for Home Care (RAI-HC). This assessment has been mandated for use in these two regions and the indicators are generated directly from items within the assessment. The indicators are expressed as rates of negative outcomes (e.g., falls, dehydration). Client-level risk adjustment of the indicator rates was used to enable fair comparisons between the regions. Clients had a mean age of 83.2 years, the majority were female (68.6%) and the regions were very similar on these demographic characteristics. Nearly all clients (92.4%) required full assistance with instrumental activities of daily living (IADLs), approximately 35% had activities of daily living (ADL) impairments, and nearly 50% had some degree of cognitive impairment, which was higher among clients in Ontario (48.8% vs. 37.0%). The highest quality indicator rates were related to clients who had ADL/rehabilitation potential but were not receiving therapy (range: 66.8%-91.6%) and the rate of cognitive decline (65.4%-76.3%). Ontario clients had higher unadjusted rates across 18 of the 22 indicators and the unadjusted differences between the two provinces ranged from 0.6% to 28.4%. For 13 of the 19 indicators that have risk adjustment, after applying the risk adjustment methodology, the difference between the adjusted rates in the two regions was reduced. Home care clients in these two regions are experiencing a significant level of functional and cognitive impairment, health instability and daily pain. The

    Health at Every Size® (HAES®) interventions focus on healthy lifestyle by promoting behavioral changes related to diet and physical activity while emphasizing self-acceptance and well-being through an empowerment and intuitive approach. The purpose of this study was to investigate the effects of a HAES® program on intuitive eating and diet quality in women. The HAES® intervention, offered by professionals from Health and Social Services Centers in Quebec (Canada), was composed of thirteen 3-h weekly meetings and a 6-h intensive day. For this study, 216 women (1.9% normal-weight, 21.1% overweight, 77.0% obese) who took part to the HAES program were compared to 110 women (3.9% normal-weight, 23.3% overweight, 72.8% obese) from a control group (waiting list). Intuitive eating was assessed using the Intuitive Eating Scale and diet quality was evaluated through the calculation of the Healthy Eating Index (HEI) from a validated web-based self-administrated food frequency questionnaire. Measurements were performed at baseline, post-intervention, and at one-year follow-up. Women who participated in the HAES® program significantly increased their intuitive eating score compared to women in the control group at post-intervention and at follow-up (group by time interaction, p = 0.0002). A significant improvement in diet quality was also observed in the HAES® group in comparison with the control group at post-intervention (group by time interaction, p = 0.0139). The intuitive eating score and the HEI score were positively associated in the HAES® group at post-intervention (r = 0.20, p = 0.0237) and one-year follow-up (r = 0.22, p = 0.0359), but no such associations were noted in the control group (post-intervention, r = 0.04, p = 0.70; one-year follow-up, r = -0.15, p = 0.30). The HAES® program seems effective in improving intuitive eating and also favours improvements in diet quality. However, the association between intuitive eating and diet

    Full Text Available Our objective was to identify distinct trajectories of disease activity state (DAS and assess variation in radiographic progression, function and quality of life over the first two years of early rheumatoid arthritis (ERA. The CATCH (Canadian early ArThritis CoHort is a prospective study recruiting ERA patients from academic and community rheumatology clinics in Canada. Sequential DAS28 scores were used to identify five mutually exclusive groups in the cohort (n = 1,586 using growth-based trajectory modeling. Distinguishing baseline sociodemographic and disease variables, treatment required, and differences in radiographic progression and quality of life measures over two years were assessed. The trajectory groups are characterized as: Group 1 (20% initial high DAS improving rapidly to remission (REM; Group 2 (21% initial moderate DAS improving rapidly to REM; Group 3 (30% initial moderate DAS improving gradually to low DAS; Group 4 (19% initial high DAS improving continuously to low DAS; and Group 5 (10% initial high DAS improving gradually only to moderate DAS. Groups differed significantly in age, sex, race, education, employment, income and presence of comorbidities. Group 5 had persistent steroid requirements and the highest biologic therapy use. Group 2 had lower odds (OR 0.22, 95%CI 0.09 to 0.58 and Group 4 higher odds (OR 1.94, 95%CI 0.90 to 4.20 of radiographic progression compared to Group 1. Group 1 had the best improvement in physical function (Health Assessment Questionnaire 1.08 (SD 0.68 units, Physical Component Score (16.4 (SD 10.2 units, Mental Component Score (9.7 (SD 12.5 units and fatigue (4.1 (SD 3.3 units. In conclusion, distinct disease activity state trajectories explain variable outcomes in ERA. Early prediction of disease course to tailor therapy and addressing social determinants of health could optimize outcomes.

    Few people realize that indoor air pollution can contribute to health effects like asthma. Several agencies, notably the United States Environmental Protection Agency (EPA), have indicated that levels of indoor pollutants can be significantly higher than those found outside. As such, poor indoor air quality (IAQ) could impact the health of students and staff, as well as the educational process and costs. Many factors can influence IAQ, including building materials, furnishings, cleaning agents, pesticides, printing and copying devices, and more. Reduction in IAQ can also result from tighter buildings and reduced ventilation. This kit was developed by Health Canada in collaboration with the Indoor Air Quality Working Group of the Federal-Provincial-Territorial Committee on Environmental and Occupational Health (CEOH) to provide school officials with the tools to prevent, identify, assess, and address most indoor air problems while minimizing cost and involvement. It was suggested that trained professionals should perform the limited and well-defined set of operations and maintenance activities described in the kit.

    To study the impact of visual impairment due to either underlying ocular pathology or easily correctable refractive error on vision-related functioning and quality of life (QOL) in Vancouver's downtown eastside (VDES). Cross-sectional study. Two hundred consecutive patients seeking general medical care at the Vancouver Native Health Society (VNHS) medical clinic were included. An ocular examination was performed and a standardized history and QOL information were obtained for each participant. Effective visual impairment was classified based on patients' current refractive means. Pathological visual impairment was classified based on patients' best-corrected visual acuity (VA). Vision-related functioning was quantified using the Daily Tasks Dependent on Vision (DTDV) questionnaire. Health-related QOL was assessed using the 12-Item Short Form Health Survey (SF-12). Two hundred patients participated; they suffered, on average, 6.2 comorbid conditions. Sixty-two patients (31%) were effectively visually impaired and, of these, 14 patients (7%) were effectively blind. Ten patients (5%) had pathological eye disease to explain their visual impairment. The remaining 52 visually impaired patients (26%) had VA that normalized with correction. Difficulty with the tasks described in the DTDV questions was significantly correlated with effective visual impairment. Patients with effective visual impairment had lower Physical Composite Scores on the SF-12 in multivariate analyses. We have demonstrated a very high rate of visual impairment in a low socioeconomic population that is associated with decreased vision-dependent functioning and decreased overall physical health status. Public health efforts need to be directed toward improving easily correctable refractive error.

    Full Text Available How must n equal circles of given radius r be placed so that they cover as great a part of the area of the unit circle as possible? In this Part II of a two-part paper, a conjectured solution of this problem for n = 5 is given for r varying from the maximum packing radius to the minimum covering radius. Results are obtained by applying a mechanical model described in Part I. A generalized tensegrity structure is associated with a maximum area configuration of the 5 circles, and by using catastrophe theory, it is pointed out that the ''equilibrium paths'' have bifurcations, that is, at certain values of r, the type of the tensegrity structure and so the type of the circle configuration changes.

  13. The Discovery of Rolling Circle Amplification and Rolling Circle Transcription.

    Nucleic acid amplification is a hugely important technology for biology and medicine. While the polymerase chain reaction (PCR) has been highly useful and effective, its reliance on heating and cooling cycles places some constraints on its utility. For example, the heating step of PCR can destroy biological molecules under investigation and heat/cool cycles are not applicable in living systems. Thus, isothermal approaches to DNA and RNA amplification are under widespread study. Perhaps the simplest of these are the rolling circle approaches, including rolling circle amplification (RCA) and rolling circle transcription (RCT). In this strategy, a very small circular oligonucleotide (e.g., 25-100 nucleotides in length) acts as a template for a DNA or an RNA polymerase, producing long repeating product strands that serve as amplified copies of the circle sequence. Here we describe the early developments and studies involving circular oligonucleotides that ultimately led to the burgeoning rolling circle technologies currently under development. This Account starts with our studies on the design of circular oligonucleotides as novel DNA- and RNA-binding motifs. We describe how we developed chemical and biochemical strategies for synthesis of well-defined circular oligonucleotides having defined sequence and open (unpaired) structure, and we outline the unusual ways in which circular DNAs can interact with other nucleic acids. We proceed next to the discovery of DNA and RNA polymerase activity on these very small cyclic DNAs. DNA polymerase "rolling circle" activities were discovered concurrently in our laboratory and that of Andrew Fire. We describe the surprising efficiency of this process even on shockingly small circular DNAs, producing repeating DNAs thousands of nucleotides in length. RNA polymerase activity on circular oligonucleotides was first documented in our group in 1995; especially surprising in this case was the finding that the process occurs efficiently

    Circles of support and accountability, or Circles, use community volunteers to help reintegrate sex offenders at risk of reoffending in the community. The aims of this study are to describe the first 275 male sex offenders ('core members') in England and Wales supported by a Circle and to compare those attending the five largest Circles. As part of their monitoring activity, 10 Circles extracted data from case files, anonymised it and submitted it to Circles UK, the national oversight body. Circles have expanded rapidly with 165 (60%) of Circles commencing in the three years 2011-2013 compared with 110 in the nine years 2002-2010. Most core members were referred from the Probation Service (82%). Circles were provided to men with a range of predicted risks of reoffending - from low (26%) to very high (12%). There were some positive changes between the beginning and end of Circles, such as fewer men being unemployed and more living in their own chosen accommodation. Circles have been used to support the reintegration of a wide range of sex offenders. Given their rapid growth and flexibility, consistent recording standards are required across. These standards should be reviewed periodically to ensure all important fields of change are captured, including frequency of attendance, length per session and quality of engagement in the work.

First, we argue that social circles are inhabited by individuals whose attitudes display fit with the objectives of the social circle rather than more self-centered instrumentalism or calculation. For a test of this hypothesis, we distinguish between friendship circles and strategy-influence circles. We find that friendship circle membership is positively associated with attitudes that display empathic concern but negatively wi...

    Installation of the cryogenic distribution line (QRL) on sector 1-2, the last to be equipped. Installation began on the last sector of the cryogenic distribution line (QRL) about three weeks ahead of the revised schedule. Besides the recent start on sector 1-2, two other sectors are still being installed. QRL installation is expected to be complete by October. Installation of a single sector involves placing 325 elements and making almost 2000 internal welds. The average time now needed for installing each sector is about four and a half months, compared to the 11 months it took to install the first sector. 'Now people are very well trained and they know they can go fast with a good quality,' said QRL project engineer Germana Riddone. As proof of that quality, QRL technicians can look at the results of the latest pressure test on sector 5-6. There were no internal leaks in the sector and out of 1000 external interconnections there were only three leaks. The QRL project was hampered early on by technical prob...

    To address nutrition-related population mental health data gaps, we examined relationships among food insecurity, diet quality, and perceived mental health. Stratified and logistic regression analyses of respondents aged 19-70 years from the Canadian Community Health Survey, Cycle 2.2 were conducted ( n = 15,546). Measures included the Household Food Security Survey Module, diet quality (i.e., comparisons to the Dietary Reference Intakes , Healthy Eating Index), perceived mental health (poor versus good), sociodemographics, and smoking. In this sample, 6.9% were food insecure and 4.5% reported poor mental health. Stratified analysis of food security and mental health status by age/gender found associations for poor diet quality, protein, fat, fibre, and several micronutrients ( p -values mental health emerged for food insecurity (OR = 1.60, 95% CI 1.45-1.71), poor diet quality (1.61, 95% CI 1.34-1.81), and suboptimal intakes of folate (OR = 1.58, 95% CI 1.17-1.90) and iron (OR = 1.45, 95% CI 1.23-1.88). Population approaches that improve food security and intakes of high quality diets may protect people from poor mental health.

    To examine whether the association between emotional support and indicators of health and quality of life differs between Canadian and Latin American older adults. Cross-sectional analysis of the International Mobility in Aging Study (IMIAS). Social support from friends, family members, children and partner was measured with a previously validated social network and support scale (IMIAS-SNSS). Low social support was defined as ranking in the lowest site-specific quartile. Prevalence ratios (PR) of good health, depression and good quality of life were estimated with Poisson regression models, adjusting for age, gender, education, income and disability in activities of daily living. Kingston and Saint-Hyacinthe in Canada, Manizales in Colombia and Natal in Brazil. 1600 community-dwelling adults aged 65-74 years, n=400 at each site. Likert scale question on self-rated health, Center for Epidemiological Studies Depression Scale and 10-point analogical quality-of-life (QoL) scale. Relationships between social support and study outcomes differed between Canadian and Latin American older adults. Among Canadians, those without a partner had a lower prevalence of good health (PR=0.90; 95% CI 0.82 to 0.98), and those with high support from friends had a higher prevalence of good health (PR=1.09; 95% CI 1.01 to 1.18). Among Latin Americans, depression was lower among those with high levels of support from family (PR=0.63; 95% CI 0.48 to 0.83), children (PR=0.60; 95% CI 0.45 to 0.80) and partner (PR=0.57; 95% CI 0.31 to 0.77); good QoL was associated with high levels of support from children (PR=1.54; 95% CI 1.20 to 1.99) and partner (PR=1.31; 95% CI 1.03 to 1.67). Among older adults, different sources of support were relevant to health across societies. Support from friends and having a partner were related to good health in Canada, whereas in Latin America, support from family, children and partner were associated with less depression and better QoL.

    Full Text Available Abstract Background The aim of this study was to identify what is most important to the quality of life (QoL of those who experience homelessness by directly soliciting the views of homeless and hard-to-house Canadians themselves. These individuals live within a unique social context that differs considerably from that of the general population. To understand the life areas that are most important to them, it is critical to have direct input from target populations of homeless and hard-to-house persons. Methods Focus groups were conducted with 140 individuals aged 15 to 73 years who were homeless or hard-to-house to explore the circumstances in which they were living and to capture what they find to be important and relevant domains of QoL. Participants were recruited in Toronto, Ottawa, Montreal, and Vancouver. Content analysis was used to analyze the data. Results Six major content themes emerged: Health/health care; Living conditions; Financial situation; Employment situation; Relationships; and Recreational and leisure activities. These themes were linked to broader concepts that included having choices, stability, respect, and the same rights as other members of society. Conclusions These findings not only aid our understanding of QoL in this group, but may be used to develop measures that capture QoL in this population and help programs and policies become more effective in improving the life situation for persons who are homeless and hard-to-house.

    Although several quality indicators of colonoscopy have been defined, quality assurance activities should be directed at the measurement of quality indicators that are predictive of key screening colonoscopy outcomes. The goal of this study was to examine the association among established quality indicators and the detection of screen-relevant lesions (SRLs), adverse events, and postcolonoscopy cancers. Historical cohort study. Canadian colorectal cancer screening center. A total of 18,456 asymptomatic men and women ages 40 to 74, at either average risk or increased risk for colorectal cancer because of a family history, who underwent a screening colonoscopy from 2008 to 2010. Using univariate and multivariate analyses, we explored the association among procedural quality indicators and 3 colonoscopy outcomes: detection of SRLs, adverse events, and postcolonoscopy cancers. The crude rates of SRLs, adverse events, and postcolonoscopy cancers were 240, 6.44, and .54 per 1000 colonoscopies, respectively. Several indicators, including endoscopist withdrawal time (OR, 1.3; 95% CI, 1.2-1.4) and cecal intubation rate (OR, 13.9; 95% CI, 1.9-96.9), were associated with the detection of SRLs. No quality indicator was associated with the risk of adverse events. Endoscopist average withdrawal time over 6 minutes (OR, .12; 95% CI, .002-.85) and SRL detection rate over 20% (OR, .17; 95% CI, .03-.74) were associated with a reduced risk of postcolonoscopy cancers. Single-center study. Quality assurance programs should prioritize the measurement of endoscopist average withdrawal time and adenoma (SRL) detection rate.

  15. On a conjecture concerning helly circle graphs

    Directory of Open Access Journals (Sweden)

    Durán Guillermo

    2003-01-01

    Full Text Available We say that G is an e-circle graph if there is a bijection between its vertices and straight lines on the cartesian plane such that two vertices are adjacent in G if and only if the corresponding lines intersect inside the circle of radius one. This definition suggests a method for deciding whether a given graph G is an e-circle graph, by constructing a convenient system S of equations and inequations which represents the structure of G, in such a way that G is an e-circle graph if and only if S has a solution. In fact, e-circle graphs are exactly the circle graphs (intersection graphs of chords in a circle, and thus this method provides an analytic way for recognizing circle graphs. A graph G is a Helly circle graph if G is a circle graph and there exists a model of G by chords such that every three pairwise intersecting chords intersect at the same point. A conjecture by Durán (2000 states that G is a Helly circle graph if and only if G is a circle graph and contains no induced diamonds (a diamond is a graph formed by four vertices and five edges. Many unsuccessful efforts - mainly based on combinatorial and geometrical approaches - have been done in order to validate this conjecture. In this work, we utilize the ideas behind the definition of e-circle graphs and restate this conjecture in terms of an equivalence between two systems of equations and inequations, providing a new, analytic tool to deal with it.

    2006-01-01

    In 1927 M. Morse discovered that the number of critical points of a smooth function on a manifold is closely related to the topology of the manifold. This became a starting point of the Morse theory which is now one of the basic parts of differential topology. It is a large and actively developing domain of differential topology, with applications and connections to many geometrical problems. The aim of the present book is to give a systematic treatment of the geometric foundations of a subfield of that topic, the circle-valued Morse functions, a subfield of Morse theory.

    Protecting drinking source water quality is a critical step in ensuring a safe supply of drinking water. Increasingly, drinking source water protection programs rely on the active participation of various stakeholders with differing degrees of water science knowledge. A drinking source water quality index presents a potential communication and analysis tool to facilitate cooperation between diverse interest groups as well as represent composite water quality. We tested the effectiveness of the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) in capturing expert assessments of drinking water quality. In cooperation with a panel of drinking water quality experts we identified a core set of parameters to reflect common source water concerns. Drinking source water target values were drafted for use in the index corresponding to two basic treatment levels. Index scores calculated using the core parameter set and associated source water target values were strongly correlated with expert assessments of water quality. We recommend a modified index calculation procedure to accommodate parameters measured at different frequencies within any particular study period. The resulting drinking source water CCME WQI provides a valuable means of monitoring, communicating, and understanding surface source water quality. Copyright © 2012 Elsevier Ltd.

    Health care organizations are utilizing quality and safety (QS) teams as a mechanism to optimize care. However, there is a lack of evidence-informed best practices for creating and sustaining successful QS teams. This study aimed to understand what health care leaders viewed as barriers and facilitators to establishing/implementing and measuring the impact of Canadian acute care QS teams. Organizational senior leaders (SLs) and QS team leaders (TLs) participated. A mixed-methods sequential explanatory design included surveys (n=249) and interviews (n=89). Chi-squared and Fisher's exact tests were used to compare categorical variables for region, organization size, and leader position. Interviews were digitally recorded and transcribed for constant comparison analysis. Five qualitative themes overlapped with quantitative data: (1) resources, time, and capacity; (2) data availability and information technology; (3) leadership; (4) organizational plan and culture; and (5) team composition and processes. Leaders from larger organizations more often reported that clear objectives and physician champions facilitated QS teams ( p team, data availability, leadership, and culture. QS teams need strong, committed leaders who align initiatives to strategic directions of the organization, foster a quality culture, and provide tools teams require for their work. There are excellent opportunities to create synergy across the country to address each organization's quality agenda.

  20. Estimating sediment quality thresholds to prevent restrictions on fish consumption: Application to polychlorinated biphenyls and dioxins-furans in the Canadian Great Lakes.

    Sediment quality thresholds (SQTs) are used by a variety of agencies to assess the potential for adverse impact of sediment-associated contaminants on aquatic biota, typically benthic invertebrates. However, sedimentary contaminants can also result in elevated fish contaminant levels, triggering consumption advisories that are protective of humans. As such, SQTs that would result in fish concentrations below consumption advisory levels should also be considered. To illustrate how this can be addressed, we first calculate biota sediment accumulation factors (BSAFs) for polychlorinated biphenyls (total PCB) and polychlorinated dioxins-furans (PCDD/Fs) in the Canadian Great Lakes using measured lake sediment and fish tissue concentrations in 4 fish species, namely, lake trout, whitefish, rainbow trout, and channel catfish. Using these BSAFs and tissue residue values for fish consumption advisories employed by the Ontario Ministry of the Environment (OMOE, Canada), we derive fish consumption advisory-based SQTs (fca-SQTs) that are likely to result in fish tissue residues that are safe to eat without restriction. The PCDD/Fs fca-SQTs ranged from 6 to 128 pg toxic equivalents (TEQ)/g dry weight (dw) and were above the Canadian Council of the Ministers of the Environment (CCME) threshold effect level (TEL) of 0.85 pg TEQ/g dw. In contrast, the total PCB fca-SQTs ranged from 1 to 60 ng/g dw and were generally below the CCME's TEL of 34.1 ng/g and OMOE's lowest effect level (LEL) of 70 ng/g; however, they were consistent with the OMOE's no effect level (NEL) of 10 ng/g. The fca-SQTs derived using the BSAF as well as food chain multiplier (FCM) approach for a smaller scale system (Hamilton Harbour in Lake Ontario) corresponded well with average lakewide Lake Ontario fca-SQTs. This analysis provides approximate sediment concentrations necessary for reducing fish consumption advisories for each of the Canadian Great Lakes and emphasizes the impacts of historical

    The Global Environmental Multiscale - Modelling Air-quality and CHemistry (GEM-MACH) system (version 2) was used to carry out simulations of acid deposition for the Canadian provinces of Alberta and Saskatchewan. These model predictions include the hourly deposition of four sulphur and eleven nitrogen containing species (SO2(g), HSO3(-)(aq) , SO4(2-)(aq), particulate sulphate, and NH3(g), NO2(g), HNO3(g), NH4(+)(aq), NO3(-)(aq), HONO(g), PAN(g), HNO4(g), particulate nitrate, particulate ammonium, and gaseous organic nitrate, respectively). A two-bin aerosol size distribution configuration of GEM-MACH was used to estimate the annual deposition of these chemicals, for the period August 1, 2013 through July 31, 2014, at two resolutions—a 10km resolution North American domain and a 2.5km resolution Alberta and Saskatchewan domain. The model estimates of acid deposition from both resolutions (version 2), were used to determine the relative contributions of the different species towards total sulphur and nitrogen deposition, and to evaluate the effect of model resolution on estimates of acid deposition. The potential ecosystem impacts of acid deposition were examined via comparison of model-predicted total deposition to different sources of sulphur and nitrogen critical load data, for forest and lake ecosystems in northern Alberta and Saskatchewan. The deposition estimates were compared to observations of snowpack sulphur and nitrogen ions, collected during the winter of 2013. The processes underlying acidifying deposition in the vicinity of the Canadian oil sands were examined in more detail using the 12-bin aerosol size distribution configuration of GEM-MACH (version 2), for a period from mid-August to mid-September 2013. This time period corresponds to an aircraft measurement intensive campaign designed to examine emissions, transportation, and deposition associated with air pollution sources in the Canadian oil sands. Multiple model simulation scenarios were

  2. Q-circle measurement error

    Hearn, Chase P.; Bradshaw, Edward S.

    1991-05-01

    High-Q lumped and distributed networks near resonance are generally modeled as elementary three element RLC circuits. The widely used Q-circle measurement technique is based on this assumption. It is shown that this assumption can lead to errors when measuring the Q-factor of more complex resonators, particularly when heavily loaded by the external source. In the Q-circle technique, the resonator is assumed to behave as a pure series (or parallel) RLC circuit and the intercept frequencies are found experimentally at which the components of impedance satisfy the absolute value of Im(Z) = Re(Z) (unloaded Q) and absolute value of Im(Z) = Ro+Re(Z) (loaded Q). The Q-factor is then determined as the ratio of the resonant frequency to the intercept bandwidth. This relationship is exact for simple series or parallel RLC circuits, regardless of the Q-factor, but not for more complex circuits. This is shown to be due to the fact that the impedance components of the circuit vary with frequency differently from those in a pure series RLC circuit, causing the Q-factor as determined above to be in error.

    The U.S. Geological Survey, in cooperation with the city of Oklahoma City, collected water-quality samples from the North Canadian River at the streamflow-gaging station near Harrah, Oklahoma (Harrah station), since 1968, and at an upstream streamflow-gaging station at Britton Road at Oklahoma City, Oklahoma (Britton Road station), since 1988. Statistical summaries and frequencies of detection of water-quality constituent data from water samples, and summaries of water-quality constituent data from continuous water-quality monitors are described from the start of monitoring at those stations through 2009. Differences in concentrations between stations and time trends for selected constituents were evaluated to determine the effects of: (1) wastewater effluent discharges, (2) changes in land-cover, (3) changes in streamflow, (4) increases in urban development, and (5) other anthropogenic sources of contamination on water quality in the North Canadian River downstream from Oklahoma City. Land-cover changes between 1992 and 2001 in the basin between the Harrah station and Lake Overholser upstream included an increase in developed/barren land-cover and a decrease in pasture/hay land cover. There were no significant trends in median and greater streamflows at either streamflow-gaging station, but there were significant downward trends in lesser streamflows, especially after 1999, which may have been associated with decreases in precipitation between 1999 and 2009 or construction of low-water dams on the river upstream from Oklahoma City in 1999. Concentrations of dissolved chloride, lead, cadmium, and chlordane most frequently exceeded the Criterion Continuous Concentration (a water-quality standard for protection of aquatic life) in water-quality samples collected at both streamflow-gaging stations. Visual trends in annual frequencies of detection were investigated for selected pesticides with frequencies of detection greater than 10 percent in all water samples

    Short-scale interactions yield large-scale vegetation patterns that, in turn, shape ecosystem function across landscapes. Fairy circles, which are circular patches bare of vegetation within otherwise continuous landscapes, are characteristic features of semiarid grasslands. We report the occurrence of submarine fairy circle seascapes in seagrass meadows and propose a simple model that reproduces the diversity of seascapes observed in these ecosystems as emerging from plant interactions within the meadow. These seascapes include two extreme cases, a continuous meadow and a bare landscape, along with intermediate states that range from the occurrence of persistent but isolated fairy circles, or solitons, to seascapes with multiple fairy circles, banded vegetation, and

    2010-07-01

    Full Text Available The article introduces the E-learning Circle, a tool developed to assure the quality of the software design process of e-learning systems, considering pedagogical principles as well as technology. The E-learning Circle consists of a number of concentric circles which are divided into three sectors. The content of the inner circles is based on pedagogical principles, while the outer circle specifies how the pedagogical principles may be implemented with technology. The circle’s centre is dedicated to the subject taught, ensuring focus on the specific subject’s properties. The three sectors represent the student, the teacher and the learning objectives. The strengths of the E-learning Circle are the compact presentation combined with the overview it provides, as well as the usefulness of a design tool dealing with complexity, providing a common language and embedding best practice. The E-learning Circle is not a prescriptive method, but is useful in several design models and processes. The article presents two projects where the E-learning Circle was used as a design tool.

    The circle of Willis is a major collateral pathway important in ischemic conditions. The aim of our study was to assess the structural characteristics of the circle of Willis within the Turkish adult population, along with variations and arteries involved in the measurement of diameters and lengths on cranial computed tomography angiography (CTA). One hundred adult patients who underwent CTA images were evaluated retrospectively. Results of the study revealed 82% adult, 17% fetal, and 1% transitional configurations. A complete polygonal structure was observed in 28% of cases. Variations of the circle of Willis were more common in the posterior portion. Hypoplasia was found to be the most common variation and was observed as a maximum in the posterior communicating artery (AComP). The patency and size of arteries in the circle of Willis are important in occlusive cerebrovascular diseases and cerebrovascular surgery. Although CTA is an easily accessible non-invasive clinical method for demonstrating the vascular structure, CTA should be evaluated taking into account image resolution quality and difficulties in the identification of small vessels.

However, there is a lack of evidence-informed best practices for creating and sustaining successful QS teams. This study aimed to understand what health care leaders viewed as barriers and facilitators to establishing/implementing and measuring the impact of Canadian acute care QS teams.Methods: Organizational senior leaders (SLs and QS team leaders (TLs participated. A mixed-methods sequential explanatory design included surveys (n=249 and interviews (n=89. Chi-squared and Fisher’s exact tests were used to compare categorical variables for region, organization size, and leader position. Interviews were digitally recorded and transcribed for constant comparison analysis.Results: Five qualitative themes overlapped with quantitative data: (1 resources, time, and capacity; (2 data availability and information technology; (3 leadership; (4 organizational plan and culture; and (5 team composition and processes. Leaders from larger organizations more often reported that clear objectives and physician champions facilitated QS teams (p<0.01. Fewer Eastern respondents viewed board/senior leadership as a facilitator (p<0.001, and fewer Ontario respondents viewed geography as a barrier to measurement (p<0.001. TLs and SLs differed on several factors, including time to meet with the team, data availability, leadership, and culture.Conclusion: QS teams need strong, committed leaders who align initiatives to strategic directions of the organization, foster a quality culture, and provide tools teams require for their work. There are excellent opportunities to create synergy across the country to address each

  19. Quality of life in patients with diabetic foot ulcers: validation of the Cardiff Wound Impact Schedule in a Canadian population.

    Science.gov (United States)

    Jaksa, Peter J; Mahoney, James L

    2010-12-01

    The purpose of this study was to evaluate and validate the Cardiff Wound Impact Schedule (CWIS), a disease-specific quality-of-life measure, in a diabetic foot ulcer (DFU) population. Patients with DFUs have restrictions as part of their treatment and rehabilitation, which can affect health-related quality of life (HRQoL). Because of the high number of comorbidities experienced in diabetes, a disease-specific quality-of-life measure is needed to best assess the affect of a foot ulcer on HRQoL. Patients with DFUs completed the CWIS and a World Health Organization generic quality-of-life questionnaire. Validity was assessed by comparing domains of the questionnaires. Patients were categorised using the University of Texas wound classification system. Mean CWIS scores were compared between categories to assess the questionnaire's ability to differentiate wound severity. Patients with open ulcers scored significantly lower on the CWIS than those with healed ulcers. Correlations between questionnaire domains were as follows: Social Life with Social Functioning (r = 0·641, P Quality of Life with Vitality (r = 0·425, P < 0·01). However, there was no significant difference in mean CWIS scores between categories of wound severity. We have demonstrated the ability of the CWIS in assessing HRQoL in a DFU population and its ability to differentiate between healed and non healed states. © 2010 The Authors.

  20. Observations and impacts of transported Canadian wildfire smoke on ozone and aerosol air quality in the Maryland region on June 9-12, 2015.

    Science.gov (United States)

    Dreessen, Joel; Sullivan, John; Delgado, Ruben

    2016-09-01

    Canadian wildfire smoke impacted air quality across the northern Mid-Atlantic (MA) of the United States during June 9-12, 2015. A multiday exceedance of the new 2015 70-ppb National Ambient Air Quality Standard (NAAQS) for ozone (O3) followed, resulting in Maryland being incompliant with the Environmental Protection Agency's (EPA) revised 2015 O3 NAAQS. Surface in situ, balloon-borne, and remote sensing observations monitored the impact of the wildfire smoke at Maryland air quality monitoring sites. At peak smoke concentrations in Maryland, wildfire-attributable volatile organic compounds (VOCs) more than doubled, while non-NOx oxides of nitrogen (NOz) tripled, suggesting long range transport of NOx within the smoke plume. Peak daily average PM2.5 was 32.5 µg m(-3) with large fractions coming from black carbon (BC) and organic carbon (OC), with a synonymous increase in carbon monoxide (CO) concentrations. Measurements indicate that smoke tracers at the surface were spatially and temporally correlated with maximum 8-hr O3 concentrations in the MA, all which peaked on June 11. Despite initial smoke arrival late on June 9, 2015, O3 production was inhibited due to ultraviolet (UV) light attenuation, lower temperatures, and nonoptimal surface layer composition. Comparison of Community Multiscale Air Quality (CMAQ) model surface O3 forecasts to observations suggests 14 ppb additional O3 due to smoke influences in northern Maryland. Despite polluted conditions, observations of a nocturnal low-level jet (NLLJ) and Chesapeake Bay Breeze (BB) were associated with decreases in O3 in this case. While infrequent in the MA, wildfire smoke may be an increasing fractional contribution to high-O3 days, particularly in light of increased wildfire frequency in a changing climate, lower regional emissions, and tighter air quality standards. The presented event demonstrates how a single wildfire event associated with an ozone exceedance of the NAAQS can prevent the Baltimore region

    Tobacco and non-tobacco-based waterpipe smoking has increased exponentially in many countries in recent decades, particularly among youth and young adults. Although tobacco smoking is banned in many indoor public places, waterpipe smoking, ostensibly non-tobacco, continues in Ontario and other jurisdictions where only tobacco smoking is prohibited. This study assessed air quality and exposure in waterpipe cafes using multiple methods and markers. Indoor (n=12) and outdoor (n=5) air quality was assessed in Toronto, Canada waterpipe cafes from 30 August to 11 October 2012. Real-time measurements of air nicotine, fine particulate matter less than 2.5 microns in diameter (PM2.5) and ambient carbon monoxide (CO) were collected in 2 h sessions. Levels of CO in breath were collected in non-smoking field staff before entering and upon leaving venues. Observations of occupant behaviour, environmental changes and venue characteristics were also recorded. In indoor venues, mean values were 1419 µg/m(3) for PM2.5, 17.7 ppm for ambient CO, and 3.3 µg/m(3) for air nicotine. Levels increased with increasing number of active waterpipes. On outdoor patios, mean values were 80.5 µg/m(3) for PM2.5, 0.5 ppm for ambient CO, and 0.6 µg/m(3) for air nicotine. Air quality levels in indoor waterpipe cafes are hazardous for human health. Outdoor waterpipe cafes showed less harmful particulate levels than indoors, but mean PM2.5 levels (80.5 µg/m(3)) were still 'poor'. Staff and patrons of waterpipe cafes are exposed to air quality levels considered hazardous to human health. Results support eliminating waterpipe smoking in hospitality venues indoors and out.

    2016-01-01

    ABSTRACT Circle dance, which derives from the tradition of folk dances, is practised worldwide. This article explores the meanings participants attribute to it. In-depth interviews with 39 participants, teachers and coordinators of teacher training programmes from the circle dance network in the United Kingdom were undertaken. Applying a constructivist grounded theory approach, major categories, representing respectively the experiences of circle dance participants, teachers and coordinators, were developed. This article specifically focuses on the first major category, termed “I can't imagine life without it”, which relates to the experience of 22 dancers. From an occupational perspective, the study reveals how participants realise a sense of meaning and satisfaction through engagement in circle dance and the potential contribution of this occupation to well-being.

    Motivated by potential applications in architecture, we study Darboux cyclides. These algebraic surfaces of order ≤4 are a superset of Dupin cyclides and quadrics, and they carry up to six real families of circles. Revisiting the classical approach to these surfaces based on the spherical model of 3D Möbius geometry, we provide computational tools for the identification of circle families on a given cyclide and for the direct design of those. In particular, we show that certain triples of circle families may be arranged as so-called hexagonal webs, and we provide a complete classification of all possible hexagonal webs of circles on Darboux cyclides. © 2011 Elsevier B.V.

  5. Robust Circle Detection Using Harmony Search

    Directory of Open Access Journals (Sweden)

    Jaco Fourie

    2017-01-01

    Full Text Available Automatic circle detection is an important element of many image processing algorithms. Traditionally the Hough transform has been used to find circular objects in images but more modern approaches that make use of heuristic optimisation techniques have been developed. These are often used in large complex images where the presence of noise or limited computational resources make the Hough transform impractical. Previous research on the use of the Harmony Search (HS in circle detection showed that HS is an attractive alternative to many of the modern circle detectors based on heuristic optimisers like genetic algorithms and simulated annealing. We propose improvements to this work that enables our algorithm to robustly find multiple circles in larger data sets and still work on realistic images that are heavily corrupted by noisy edges.

    Little is known about patients exiting home hemodialysis. We sought to characterize the reasons, clinical characteristics, and pre-exit health care team interactions of patients on home hemodialysis who died or underwent modality conversion (negative disposition) compared with prevalent patients and those who were transplanted (positive disposition). We conducted an audit of all consecutive patients incident to home hemodialysis from January of 2010 to December of 2014 as part of ongoing quality assurance. Records were reviewed for the 6 months before exit, and vital statistics were assessed up to 90 days postexit. Ninety-four patients completed training; 25 (27%) received a transplant, 11 (12%) died, and 23 (25%) were transferred to in-center hemodialysis. Compared with the positive disposition group, patients in the negative disposition group had a longer mean dialysis vintage (3.15 [SD=4.98] versus 1.06 [SD=1.16] years; P=0.003) and were performing conventional versus a more intensive hemodialysis prescription (23 of 34 versus 23 of 60; Pday mortality among patients undergoing modality conversion was 26%. Over a 6-year period, approximately one third of patients exited the program due to death or modality conversion. Patients who die or transfer to another modality have significantly higher health care resource utilization (e.g., hospitalization, respite treatments, nursing time, etc.).

    To describe sleep duration and sleep characteristics, and to examine the associations between sleep duration and characteristics and body weight status, diet quality, and physical activity levels among grade 5 children in Nova Scotia. A provincially representative sample of 5,560 grade 5 children and their parents in Nova Scotia was surveyed. Parents were asked to report their child's bedtime and wake-up time, and to indicate how often their child snored or felt sleepy during the day. Dietary intake and physical activity were selfreported by children using the Harvard Youth/Adolescent Food Frequency Questionnaire and the Physical Activity Questionnaire for Children respectively. Body weight status was determined using measured heights and weights. Linear and logistic random effects models with children nested within schools were used to test for associations. Approximately half of the surveyed parents reported that their children were not getting adequate sleep at night. Longer sleep duration was statistically significantly associated with decreased risk for overweight and obesity independent of other sleep characteristics (OR = 0.82, 95% CI: 0.73, 0.91). Longer sleep duration was also associated with better diet quality and higher levels of physical activity. These findings indicate a need for health promotion strategies to encourage adequate sleep and to promote healthy sleep environments among children. Given the links among sleep, body weight status and lifestyle behaviours, these messages should be included in public health interventions aimed at preventing obesity and promoting health among children.

    Given their multifactorial nature and the fact that individual patients may have more than a single underlying cause, cosmetic practitioners should be well versed in a number of potential treatment options encompassing all facets of under-eye dark circles. New therapeutic options are also forthcoming. Longer-lasting HA fillers, wavelength tunable laser devices, and topicals speeding up healing and enhancing results after fractionated laser therapy will all serve to make the future of dark circle treatment unabatedly bright.

    Zsolt Gáspár

    2014-05-01

    Full Text Available How must n equal circles of given radius be placed so that they cover as great a part of the area of the unit circle as possible? To analyse this mathematical problem, mechanical models are introduced. A generalized tensegrity structure is associated with a maximum area configuration of the n circles, whose equilibrium configuration is determined numerically with the method of dynamic relaxation, and the stability of equilibrium is investigated by means of the stiffness matrix of the tensegrity structure. In this Part I, the principles of the models are presented, while an application will be shown in the forthcoming Part II.

  10. Yoctomole electrochemical genosensing of Ebola virus cDNA by rolling circle and circle to circle amplification.

    Science.gov (United States)

    Carinelli, S; Kühnemund, M; Nilsson, M; Pividori, M I

    2017-07-15

    This work addresses the design of an Ebola diagnostic test involving a simple, rapid, specific and highly sensitive procedure based on isothermal amplification on magnetic particles with electrochemical readout. Ebola padlock probes were designed to detect a specific L-gene sequence present in the five most common Ebola species. Ebola cDNA was amplified by rolling circle amplification (RCA) on magnetic particles. Further re-amplification was performed by circle-to-circle amplification (C2CA) and the products were detected in a double-tagging approach using a biotinylated capture probe for immobilization on magnetic particles and a readout probe for electrochemical detection by square-wave voltammetry on commercial screen-printed electrodes. The electrochemical genosensor was able to detect as low as 200 ymol, corresponding to 120 cDNA molecules of L-gene Ebola virus with a limit of detection of 33 cDNA molecules. The isothermal double-amplification procedure by C2CA combined with the electrochemical readout and the magnetic actuation enables the high sensitivity, resulting in a rapid, inexpensive, robust and user-friendly sensing strategy that offers a promising approach for the primary care in low resource settings, especially in less developed countries.

  11. PACKING CIRCLES WITHIN CIRCULAR CONTAINERS: A NEW HEURISTIC ALGORITHM FOR THE BALANCE CONSTRAINTS CASE

    Directory of Open Access Journals (Sweden)

    Washington Alves de Oliveira

    Full Text Available ABSTRACT In this work we propose a heuristic algorithm for the layout optimization for disks installed in a rotating circular container. This is a unequal circle packing problem with additional balance constraints. It proved to be an NP-hard problem, which justifies heuristics methods for its resolution in larger instances. The main feature of our heuristic is based on the selection of the next circle to be placed inside the container according to the position of the system's center of mass. Our approach has been tested on a series of instances up to 55 circles and compared with the literature. Computational results show good performance in terms of solution quality and computational time for the proposed algorithm.

  12. Function representation with circle inversion map systems

    Science.gov (United States)

    Boreland, Bryson; Kunze, Herb

    2017-01-01

    The fractals literature develops the now well-known concept of local iterated function systems (using affine maps) with grey-level maps (LIFSM) as an approach to function representation in terms of the associated fixed point of the so-called fractal transform. While originally explored as a method to achieve signal (and 2-D image) compression, more recent work has explored various aspects of signal and image processing using this machinery. In this paper, we develop a similar framework for function representation using circle inversion map systems. Given a circle C with centre õ and radius r, inversion with respect to C transforms the point p˜ to the point p˜', such that p˜ and p˜' lie on the same radial half-line from õ and d(õ, p˜)d(õ, p˜') = r2, where d is Euclidean distance. We demonstrate the results with an example.

  13. CHARACTERISTICS OF HYDROCARBON EXPLOITATION IN ARCTIC CIRCLE

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available The existence of large quantities of hydrocarbons is supposed within the Arctic Circle. Assumed quantities are 25% of the total undiscovered hydrocarbon reserves on Earth, mostly natural gas. Over 500 major and minor gas accumulations within the Arctic Circle were discovered so far, but apart from Snøhvit gas field, there is no commercial exploitation of natural gas from these fields. Arctic gas projects are complicated, technically hard to accomplish, and pose a great threat to the return of investment, safety of people and equipment and for the ecosystem. Russia is a country that is closest to the realization of the Arctic gas projects that are based on the giant gas fields. The most extreme weather conditions in the seas around Greenland are the reason why this Arctic region is the least explored and furthest from the realization of any gas project (the paper is published in Croatian .

    Easson, Amanda; Agarwal, Arnav; Duda, Stephanie; Bennett, Kathryn

    2014-09-01

    Responsible media reporting of youth suicide may reduce the risk of contagion and increase help-seeking behaviour. Accordingly, we conducted a content analysis of Canadian youth suicide newspaper articles to assess quality and summarize content (themes, age groups, populations and use of scientific evidence). The Canadian Periodical Index Quarterly (CPI.Q) was searched (2008-2012) for full-text Canadian newspaper articles using the keywords "youth" and "suicide." The top five most relevant articles as judged by CPI.Q were selected sequentially for each year (n=25). Quality was assessed using World Health Organization (WHO) guidelines for responsible media reporting. Content analysis was completed in duplicate by two reviewers. All articles addressed youth suicide generally rather than reporting exclusively on a specific death by suicide. Alignment of articles with individual WHO guideline items ranged from 16 to 60%. The most common content theme was prevention (80%). No article was judged to glamorize suicide. Help seeking was addressed in 52% of articles, but only 20% provided information on where to obtain help. Statistics were referenced more frequently than scientific research (76% vs. 28%). Our review suggests that Canadian media presents youth suicide as an issue for which hope and help exist. While the majority of reports aim to educate the public about suicide, increased use of scientific evidence about risk factors and prevention is recommended to facilitate the translation of rigorous scientific knowledge into improved mental health and reduced suicide risk among Canadian youth.

  17. Walking in circles: a modelling approach.

    Science.gov (United States)

    Maus, Horst-Moritz; Seyfarth, Andre

    2014-10-06

    Blindfolded or disoriented people have the tendency to walk in circles rather than on a straight line even if they wanted to. Here, we use a minimalistic walking model to examine this phenomenon. The bipedal spring-loaded inverted pendulum exhibits asymptotically stable gaits with centre of mass (CoM) dynamics and ground reaction forces similar to human walking in the sagittal plane. We extend this model into three dimensions, and show that stable walking patterns persist if the leg is aligned with respect to the body (here: CoM velocity) instead of a world reference frame. Further, we demonstrate that asymmetric leg configurations, which are common in humans, will typically lead to walking in circles. The diameter of these circles depends strongly on parameter configuration, but is in line with empirical data from human walkers. Simulation results suggest that walking radius and especially direction of rotation are highly dependent on leg configuration and walking velocity, which explains inconsistent veering behaviour in repeated trials in human data. Finally, we discuss the relation between findings in the model and implications for human walking. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

  18. The life cycle and life span of Namibian fairy circles.

    Science.gov (United States)

    Tschinkel, Walter R

    2012-01-01

    In Namibia of southwestern Africa, the sparse grasslands that develop on deep sandy soils under rainfall between 50 and 100 mm per annum are punctuated by thousands of quasi-circular bare spots, usually surrounded by a ring of taller grass. The causes of these so-called "fairy circles" are unknown, although a number of hypotheses have been proposed. This paper provides a more complete description of the variation in size, density and attributes of fairy circles in a range of soil types and situations. Circles are not permanent; their vegetative and physical attributes allow them to be arranged into a life history sequence in which circles appear (birth), develop (mature) and become revegetated (die). Occasionally, they also enlarge. The appearance and disappearance of circles was confirmed from satellite images taken 4 years apart (2004, 2008). The frequency of births and deaths as a fraction of the total population of circles allowed the calculation of an approximate turnover rate, and from this, an estimate of circle lifespan. Lifespan appeared to vary with circle size, with small circles averaging about 24 years, and larger ones 43-75 years. Overall lifespan averaged about 41 yr. A second, independent estimate of lifespan was made by revisiting circles 2 to 9 years after their clear status had been confirmed. This resulted in a lifespan estimate of about 60 years. Any causal explanation of fairy circles must include their birth, development and death, their mean lifespan and the variation of their features under different conditions.

    Kaplan, Alan

    2014-01-01

    Objective To provide a clinical summary of the Canadian clinical practice guidelines for acute bacterial rhinosinusitis (ABRS) that includes relevant considerations for family physicians. Quality of evidence Guideline authors performed a systematic literature search and drafted recommendations. Recommendations received both strength of evidence and strength of recommendation ratings. Input from external content experts was sought, as was endorsement from Canadian medical societies (Association of Medical Microbiology and Infectious Disease Canada, Canadian Society of Allergy and Clinical Immunology, Canadian Society of Otolaryngology—Head and Neck Surgery, Canadian Association of Emergency Physicians, and the Family Physicians Airways Group of Canada). Main message Diagnosis of ABRS is based on the presence of specific symptoms and their duration; imaging or culture are not needed in uncomplicated cases. Treatment is dependent on symptom severity, with intranasal corticosteroids (INCSs) recommended as monotherapy for mild and moderate cases, although the benefit might be modest. Use of INCSs plus antibiotics is reserved for patients who fail to respond to INCSs after 72 hours, and for initial treatment of patients with severe symptoms. Antibiotic selection must account for the suspected pathogen, the risk of resistance, comorbid conditions, and local antimicrobial resistance trends. Adjunct therapies such as nasal saline irrigation are recommended. Failure to respond to treatment, recurrent episodes, and signs of complications should prompt referral to an otolaryngologist. The guidelines address situations unique to the Canadian health care environment, including actions to take during prolonged wait periods for specialist referral or imaging. Conclusion The Canadian guidelines provide up-to-date recommendations for diagnosis and treatment of ABRS that reflect an evolving understanding of the disease. In addition, the guidelines offer useful tools to help

    The concept of circles is an ancient concept that has appeared since Ancient Egypt from which this concept gives many significant contributions in mathematics’ development until now. Nevertheless, the concept of circles hides many uncover mysterious features that are of applications in mathematics. One of the mysterious features is the Nine-Point Circle. This Nine-point circle is also known as Euler’s circle, six-point circle, Feuerbach’s circle, the twelve-point circle, and many others. Because of these different names, there have been misunderstand among mathematicians about the Nine-Point Circle’s history. Besides, the discussion of Nine-Point Circle can be used to be an initial material to explain elementary geometry topic in junior high school’s level curriculum of 2013. Therefore, this concept needs to be delivered to the students as a geometry introduction. A possible form of the integration historical aspect of Nine-point circle is suggested in this paper as well as its importance in the curriculum of 2013.

    For certain designs, we observe a rather peculiar defect during phase-shift mask production. At distinct positions on the mask, the chrome disappears within the second level process in almost perfect half circles. This effect can even be observed if no etching is applied at all. The root cause of this defect is electrochemical dissolving of chrome in DI water during the development rinse process, which appears at locations where the chrome is in contact to the developer rinse medium. In this publication we describe the experimental set-up to investigate the root cause mechanism and propose solutions to overcome the effect.

In this paper, a graphical method (GM is proposed to solve the GCR problems based on the celestial meridian diagram (CMD in celestial navigation. Unlike developed algebraic methods, the GM is a geometric method. Appling computer software to graph, the GM does not use any equations but is as accurate as using algebraic methods. In addition, the GM, which emphasizes the rotational surface, can depict a GCR and judge its benefit.

    Full Text Available Many new types of breakwaters have been constructed of lateto fulfill the ever increasing demand of marine traffic. The quarter circle breakwater (QBW is a recent type of breakwater developed on the lines of an earlier semicircular breakwater (SBW. QBW may be without perforations, seaside perforated or both sides perforated. A series of laboratory experiments were conducted in a two dimensional monochromatic wave flume on an emerged seaside perforated non-overtopping quarter circle breakwater model to study its stability against sliding. The scale of the model was 1:30. A range of incident wave heights (Hi and wave periods (T were generated in the flume simulating the wave climate off Mangaluru coast in the Karnataka State of India. The experimental data so collected was analyzed to understand the variation of the non-dimensional stability parameter with incident wave steepness for different values of dimensionless depth parameter In the end a nomogram was developed for computing the sliding stability of the breakwater.

  7. A mechanism for ramified rolling circle amplification

    Directory of Open Access Journals (Sweden)

    Smith James H

    2010-12-01

    Full Text Available Abstract Background Amplification of single-stranded DNA circles has wide utility for a variety of applications. The two-primer ramified rolling circle amplification (RAM reaction provides exponential DNA amplification under isothermal conditions, creating a regular laddered series of double-stranded DNA products. However, the molecular mechanism of the RAM reaction remains unexplained. Results A RAM reaction model predicts exponential accumulation of a double-stranded DNA product size series, and product-size ratios, that are consistent with observed RAM reaction products. The mechanism involves generation of a series of increasing size intermediate templates; those templates produce RAM products and recursively generate smaller intermediate templates. The model allows prediction of the number of rounds of circular template replication. Real-time RAM reaction data are consistent with the model. Analysis of RAM reaction products shows exponential growth limitation consistent with the model's predictions. Conclusions The model provides a rationale for the observed products of the RAM reaction, and the molecular yield among those products. Experimental results are consistent with the model.

  8. Neurodynamics in Randomly Coupled Circle Maps

    Matsuno, Tetsuya; Toko, Kiyoshi; Yamafuji, Kaoru

    1996-05-01

    The dynamics of retrieval processes in a system composed of coupled circle maps is studied by means of a statistical method and numerical simulations. Phase patterns are embedded in coupling parameters so that the system may work as an associative memory system. A parameter, which is an amplification factor multiplied to all the coupling strengths, is introduced for investigating the effect of the strength of the coupling nonlinearity on the behavior of the system concerned. The statistical method provides a set of time evolution equations representing the macroscopic behavior. It is found that the storage capacity is considerably enhanced by the introduced amplification factor. It is also shown that the system exhibits macroscopic chaotic oscillations when the strength of the coupling is sufficiently large. Moreover, the clustering is observed, as in other types of the globally coupled nonlinear systems.

    2015-06-01

    Currently, general surgeons provide about 50% of endoscopy services across Canada and an even greater proportion outside large urban centres. It is essential that endoscopy remain a core component of general surgery practice and a core competency of general surgery residency training. The Canadian Association of General Surgeons Residents Committee supports the position that quality endoscopy training for all Canadian general surgery residents is in the best interest of the Canadian public. However, the means by which quality endoscopy training is achieved has not been defined at a national level. Endoscopy training in Canadian general surgery residency programs requires standardization across the country and improved measurement to ensure that competency and basic credentialing requirements are met.

    2014-01-01

    The purpose of this paper is to use a systems lens to assess the comparative performance of healthcare supply chains and provide guidance for their improvement. A well-established and rigorous multi-method audit methodology, based on the uncertainty circle model, yields an objective assessment of value stream performance in eight Australasian public sector hospitals. Cause-effect analysis identifies the major barriers to achieving smooth, seamless flows. Potentially high-leverage remedial actions identified using systems thinking are examined with the aid of an exemplar case. The majority of the healthcare value streams studied are underperforming compared with those in the European automotive industry. Every public hospital appears to be caught in the grip of vicious circles of system uncertainty, in large part being caused by problems of their own making. The single exception is making good progress towards seamless functional integration, which has been achieved by elevating supply chain management to a core competence; having a clearly articulated supply chain vision; adopting a systems approach; and, managing supplies with accurate information. The small number of cases limits the generalisability of the findings at this time. Hospital supply chain managers endeavouring to achieve smooth and seamless supply flows should attempt to elevate the status of supplies management within their organisation to that of a core competence, and should use accurate information to manage their value streams holistically as a set of interwoven processes. A four-level prism model is proposed as a useful framework for thus improving healthcare supply delivery systems. Material flow concepts originally developed to provide objective assessments of value stream performance in commercial settings are adapted for use in a healthcare setting. The ability to identify exemplar organisations via a context-free uncertainty measure, and to use systems thinking to identify high

    2014-01-01

    Full Text Available Individuals with obstructive sleep apnea (OSA experience sleep fragmentation and poor sleep quality that results in daytime sleepiness, which impairs performance during driving and leads to an increased risk for collisions. Not surprisingly, observational studies have shown that patients with OSA experience a two- to 10-fold higher risk for collision compared with healthy controls. Although treatment would clearly mitigate these risks, there is no current Canadian position on driving and OSA. This article, the first Canadian position statement addressing the issue, provides an overview of provincial regulations and proposes recommendations with regard to driving in patients with OSA.

    1995-01-01

    Circle packings are configurations of circles with specified patterns of tangency, and lend themselves naturally to computer experimentation and visualization. Maps between them display, with surprising faithfulness, many of the geometric properties associated with classical analytic functions. This paper introduces the fundamentals of an emerging "discrete analytic function theory'' and investigates connections with the classical theory. It then describes several experiment...

    Patient engagement through shared decision-making (SDM) is increasingly seen as a key component for patient safety, patient satisfaction, and quality of care. Current SDM models do not adequately account for medical and environmental contexts, which may influence medical decisions in the hospital. We identified leading SDM models and reviews to inductively construct a novel SDM model appropriate for the inpatient setting. A team of medicine and pediatric hospitalists reviewed the literature to integrate core SDM concepts and processes and iteratively constructed a synthesized draft model. We then solicited broad SDM expert feedback on the draft model for validation and further refinement. The SDM 3 Circle Model identifies 3 core categories of variables that dynamically interact within an "environmental frame." The resulting Venn diagram includes overlapping circles for (1) patient/family, (2) provider/team, and (3) medical context. The environmental frame includes all external, contextual factors that may influence any of the 3 circles. Existing multistep SDM process models were then rearticulated and contextualized to illustrate how a shared decision might be made. The SDM 3 Circle Model accounts for important environmental and contextual characteristics that vary across settings. The visual emphasis generated by each "circle" and by the environmental frame direct attention to often overlooked interactive forces and has the potential to more precisely define, promote, and improve SDM. This model provides a framework to develop interventions to improve quality and patient safety through SDM and patient engagement for hospitalists. © 2017 Society of Hospital Medicine.

  8. Nuclear communications : A Canadian perspective

    1994-04-15

    Times have changed since the early days of nuclear energy when it was a symbol of a brave new world, Public information strategies have evolved to meet increasing public concerns, and have shifted from being a largely unfocused attempt at publicity to being more concerned with managing issues and solving problems. This paper describes some of the salient features of the Canadian experience in nuclear communications and examines four key aspects: opinion and attitude research; media relations; coeducation; and advertising. It also addresses the challenge of responding to the allegations and tactics of those who are actively hostile to nuclear energy, and recommends that the principles of Total Quality Management and of organizational effectiveness be applied more thorough and more consistently to the public affairs function.

    Infraorbital dark circles refer to the conditions that present with darkness of the infraorbital eyelids. Although it is not a medical concern, it can be a cosmetic concern for a large number of individuals. Moreover, clear definition and possible causes have not been elucidated. To review the possible causes and treatment options for infraorbital dark circles. The article is based on a review of the medical literature and the author's clinical experience in treating infraorbital dark circles. Possible causative factors of infraorbital dark circles include excessive pigmentation, thin and translucent lower eyelid skin overlying the orbicularis oculi muscle, and shadowing due to skin laxity and tear trough, but because multiple factors cause infraorbital dark circles in the majority of patients, it is essential to identify the cause and choose the appropriate treatment according to the cause.

  10. Reducing dietary sodium intake: the Canadian context.

    Science.gov (United States)

    Barr, Susan I

    2010-02-01

    Sodium is a required nutrient; Adequate Intakes for adults range from 1200 to 1500 mg*day(-1), depending on age. The Tolerable Upper Intake Level (UL) for sodium is 2300 mg*day(-1) for adults, based on the relationship between sodium intake and increased blood pressure. Elevated blood pressure, which is prevalent among Canadians, is, in turn, a major risk factor for stroke, cardiovascular disease, and renal disease. Sodium intake is not the only determinant of blood pressure; other modifiable risk factors include relative mass, physical activity, overall dietary quality, and alcohol consumption. However, because >90% of adult Canadian men and two thirds of Canadian women have sodium intakes above the UL, Health Canada's Working Group on Dietary Sodium Reduction has been charged with developing, implementing, and overseeing a strategy to reduce Canadians' sodium intakes. It is estimated that approximately 75% of dietary sodium is added during food processing; in addition to taste and palatability, sodium also has functional roles in food manufacturing and preservation, although the amounts used often exceed those required. Because of the central role of processed foods in sodium intake, the strategy proposed by Health Canada's Working Group includes voluntary reduction of sodium in processed foods and foods sold in food service establishments. It will also include an education and awareness campaign, and research and surveillance. Initiatives to reduce sodium in other parts of the world have demonstrated that it will be challenging to reduce sodium intake to the recommended range and will likely require many years to accomplish.

    2012-10-01

    Full Text Available Background : Sleep facilitates the consolidation of fear extinction memory. Nightmares and insomnia are hallmark symptoms of posttraumatic stress disorder (PTSD, possibly interfering with fear extinction and compromising recovery. A perpetual circle may develop when sleep disturbances increase the risk for PTSD and vice versa. To date, therapeutic options for alleviating sleep disturbances in PTSD are limited. Methods : We conducted three studies to examine the relationship between sleep and posttraumatic symptoms: (1 a prospective longitudinal cohort study examining the impact of pre-deployment insomnia symptoms and nightmares on the development of PTSD; (2 a cross-sectional study examining subjective sleep measures, polysomnography, endocrinological parameters, and memory in veterans with PTSD, veterans without PTSD, and healthy controls (HCs; (3 a randomized controlled trial (RCT (n=14 comparing the effect of prazosin and placebo on sleep disturbances in veterans with PTSD. In addition to these studies, we systematically reviewed the literature on treatment options for sleep disturbances in PTSD. Results : Pre-deployment nightmares predicted PTSD symptoms at 6 months post-deployment; however, insomnia symptoms did not. Furthermore, in patients with PTSD, a correlation between the apnea index and PTSD severity was observed, while obstructive sleep apnea syndrome was not more prevalent. We observed a significant increase in awakenings during sleep in patients with PTSD, which were positively correlated with adrenocorticotropic hormone (ACTH levels, negatively correlated with growth hormone (GH secretion, and the subjective perception of sleep depth. Also, heart rate was significantly increased in PTSD patients. Interestingly, plasma levels of GH during the night were decreased in PTSD. Furthermore, GH secretion and awakenings were independent predictors for delayed recall, which was lower in PTSD. In our RCT, prazosin was not associated with

To accomplish these objective the committee assembled a stim­ ulating programme of lectures and talks. Six ...

  15. Circle of Willis atherosclerosis, Alzheimer's disease and the Dean number.

    Science.gov (United States)

    Ismailov, Rovshan M

    2013-10-26

    The important role of atherosclerosis in pathophysiology of Alzheimer's Disease has become evident. Mechanisms such as hyperlipidemia, inflammation, abdominal obesity and insulin resistance are important yet they may not fully explain the specific involvement of the Circle of Willis in these pathologies. The Circle of Wills is a complex geometrical structure which has several areas with different curvature as well as various branching angles of vessels composing the circle. The hemodynamics in this region should take into account the Dean number which indicates the influence of curvature on the resistance to blood flow. Thus, areas with various curvature and angles may have different hemodynamics and there are certain areas in the Circle of Willis that are more likely to develop atherosclerotic changes. Therefore, this could suggest the novel pathophysiological pathway resulting from the geometric peculiarities of the Circle of Willis. One of the directions of future research is to examine whether specific areas of the Circle of Willis are more likely to develop atherosclerotic changes compared to other ones. Selective areas of the Circle of Willis affected by atherosclerotic changes could indicate the primary role of atherosclerosis promoting Alzheimer's disease although other pathophysiological mechanisms suggesting the opposite direction should be also examined in prospective studies.

  17. Tuberculosis in Aboriginal Canadians

    Directory of Open Access Journals (Sweden)

    Vernon H Hoeppner

    2000-01-01

    Full Text Available Endemic tuberculosis (TB was almost certainly present in Canadian aboriginal people (aboriginal Canadians denotes status Indians, Inuit, nonstatus Indians and metis as reported by Statistics Canada before the Old World traders arrived. However, the social changes that resulted from contact with these traders created the conditions that converted endemic TB into epidemic TB. The incidence of TB varied inversely with the time interval from this cultural collision, which began on the east coast in the 16th century and ended in the Northern Territories in the 20th century. This relatively recent epidemic explains why the disease is more frequent in aboriginal children than in Canadian-born nonaboriginal people. Treatment plans must account for the socioeconomic conditions and cultural characteristics of the aboriginal people, especially healing models and language. Prevention includes bacillus Calmette-Guerin vaccination and chemoprophylaxis, and must account for community conditions, such as rates of suicide, which have exceeded the rate of TB. The control of TB requires a centralized program with specifically directed funding. It must include a program that works in partnership with aboriginal communities.

    We define a "circle Euler characteristic" of a circle action on a compact manifold or finite complex X. It lies in the first Hochschild homology group of ZG where G is the fundamental group of X. It is analogous in many ways to the ordinary Euler characteristic. One application is an intuitively satisfying formula for the Euler class (integer coefficients) of the normal bundle to a smooth circle action without fixed points on a manifold. In the special case of a 3-dimensional Seifert fibered ...

  2. The rolling circle for phiX DNA replication. II. Synthesis of single-stranded circles.

    Science.gov (United States)

    Dressler, D

    1970-12-01

    varphiX-infected cells have been allowed to incorporate tritiated thymidine late in the phage life cycle when single-stranded circles are the product of DNA synthesis. Virtually all of the radioactivity is recovered in a continuum of actively replicating viral DNA molecules. These molecules are termed rolling circle intermediates because they are characterized by three structural properties. They possess positive strands that are longer than the length of a mature viral genome, and negative strands that are covalently closed single-stranded circles. The 3' termini of the long positive strands lie upon the template rings, while the 5' ends are free in solution. From these experimental data, the basic mode of synthesis is deduced to involve the continuous elongation of the open positive strand by endless copying around the circular negative strand template. As new bases are added to the template-bound (3') end of the positive strand, the distal (5') end is displaced from the template ring as a single-stranded tail of increasing length. It is the tail which serves as the source of material for progeny chromosomes. These data confirm our characterization of this varphiX intermediate, which initially was based only on the possession of long positive strands, and extend this characterization to include experimental statements about the circular nature of the template DNA strand, and the 5' to 3' direction of polynucleotide chain growth within the intermediate. Moreover, the description can now be applied to all of the molecules which acquire label during a pulse.

    We are reporting a new simple optical element to generate halos. We have observed interesting patterns of light scattering in Plateau borders in foams. In analogy to the atmospheric phenomena known as parhelic circle, sun dogs, and sun pillars, we have named the features of the patterns observed as parlaseric circle, laser dogs, and laser pillars. The triangular symmetry of the Plateau borders is analogous to the hexagonal symmetry of ice crystals which produce these atmospheric phenomena. Working with one Plateau border at a time, we have observed wave optics phenomena that are not perceived in the atmospheric phenomena, such as diffraction and interference. - Highlights: • We obtained halo formation from light scattering in a Plateau border using an experiment. • We explained halo formation using geometrical theory of diffraction. • An optical element based on a Plateau border is proposed. • We compared some aspects of the parhelic circle with the parlaseric circle.

    Full Text Available Abstract Background Organizational features can affect how staff view their quality of work life. Determining staff perceptions about quality of work life is an important consideration for employers interested in improving employee job satisfaction. The purpose of this study was to identify organization specific predictors of job satisfaction within a health care system that consisted of six independent health care organizations. Methods 5,486 full, part and causal time (non-physician staff on active payroll within six organizations (2 community hospitals, 1 community hospital/long-term care facility, 1 long-term care facility, 1 tertiary care/community health centre, and 1 visiting nursing agency located in five communities in Central West Ontario, Canada were asked to complete a 65-item quality of work life survey. The self-administered questionnaires collected staff perceptions of: co-worker and supervisor support; teamwork and communication; job demands and decision authority; organization characteristics; patient/resident care; compensation and benefits; staff training and development; and impressions of the organization. Socio-demographic data were also collected. Results Depending on the organization, between 15 and 30 (of the 40 potential predictor variables were found to be statistically associated with job satisfaction (univariate analyses. Logistic regression analyses identified the best predictors of job satisfaction and these are presented for each of the six organizations and for all organizations combined. Conclusions The findings indicate that job satisfaction is a multidimensional construct and although there appear to be some commonalities across organizations, some predictors of job satisfaction appear to be organization and context specific.

    We study critical invariant circles of several noble rotation numbers at the edge of breakdown for area preserving maps of the cylinder which violate the twist conditions. These circles admit essentially unique parameterizations by rotational coordinates. We present a high accuracy computation of about $10^7$ Fourier coefficients. This allows us to compute the regularity of the conjugating maps and show that, to the extent of the precision, it only depends on the tail of the continued fraction expansion.

    The coaxial circle system helps prevent heat loss during surgery, and it also acts as a humidifier. This study aimed to compare the coaxial breathing system and the conventional system in their ability to warm and moisturize inhaled gases, and we also analyzed lung function protection and saccharin clearance time in patients who underwent tympanomastoidectomy (TMT) with the aid of these two systems. Forty adult patients of ASA physical status I-II were scheduled for elective TMT. A standard volume-dependent ventilator setting was used to establish normocapnia. The coaxial circle system was used in the treated group (n=20), whereas the conventional circuit system was used in the control group (n=20). Saccharin clearance, VC (vital capacity), FRC (functional residual capacity), FEV1 (forced expiratory volume in 1 second), airway pressure, relative humidity and temperature of inspired gas, body temperature and adverse and hemodynamic effects were measured at different perioperative periods. The relative humidity (mg H2O Lt -1) of inspired gas in the treated group was higher than in the control group at 5, 15, 30, 45, 60 and 90 minutes after anesthesia induction. The temperature of inspired gas (Centigrade) in the treated group was higher than in the control group (pcircle system decreased postoperative saccharin clearance time and increased postoperative FRC, relative humidity and the temperature of inspired fresh gas, without any adverse perioperative effects in patients who underwent TMT.

  12. Models to support students’ understanding of measuring area of circles

    Science.gov (United States)

    Rejeki, S.; Putri, R. I. I.

    2018-01-01

    Many studies showed that enormous students got confused about the concepts of measuring area of circles. The main reason is because mathematics classroom practices emphasized on memorizing formulas rather than understanding concepts. Therefore, in this study, a set of learning activities were designed as an innovation in learning area measurement of circles. The activities involved two models namely grid paper and reshaping which are respectively as a means and a strategy to support students’ learning of area measurement of circles. Design research was used as the research approach to achieve the aim. Thirty-eight of 8th graders in Indonesia were involved in this study. In this study, together with the contextual problems, the grid paper and reshaping sectors, which used as the models in this learning, helped the students to gradually develop their understanding of the area measurement of circles. The grid papers plays important role in comparing and estimating areas. Whereas, the reshaping sectors might support students’ understanding of the circumference and the area measurement of circles. Those two models could be the tool for promoting the informal theory of area measurement. Besides, the whole activities gave important role on distinguishing the area and perimeter of circles.

  13. Biology coming full circle: joining the whole and the parts.

    Science.gov (United States)

    Wikswo, John P; Porter, Andrew P

    2015-01-01

    The new cover of Experimental Biology and Medicine features the hermeneutic circle of biology, a concept we have adapted from the hermeneutic principle that one understands the whole only in terms of each part and the parts only in terms of the whole. Our hermeneutic circle summarizes the course of experimental biology through 2500 years of the achievements of reductionist research (understanding the parts), which culminates in our ability to rapidly sequence the genome. Rather than returning along the same path in a constructionist approach that simply builds upon this knowledge, but in reverse, an alternative is to close the circle with synthetic constructions that seek to integrate the full complexity of biological and physiological systems (understanding the whole), of which organs-on-chips are one example. This closing of the circle cannot be a comprehensively accurate representation of biology, but it can be a synthetic one that effectively defines particular biological subsystems. The illustration of the hermeneutic circle of biology is also intended to suggest both the multiple cycles that may be required to reach such a synthesis and the expansion of the circle in an outward spiral as knowledge increases. Our commentary explains the symbolism of the new cover in a philosophical and scientific discussion. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Iron deficiency is the most common nutritional deficiency in the world, but little is known about the iron status of people in Canada, where the last estimates are from 1970-1972. The data are from cycle 2 (2009 to 2011) of the Canadian Health Measures Survey, which collected blood samples from a nationally representative sample of Canadians aged 3 to 79. Descriptive statistics (percentages, arithmetic means, geometric means) were used to estimate hemoglobin and serum ferritin concentrations, and other markers of iron status. Analyses were performed by age/sex group, household income, self-perceived health, diet, and use of iron supplements. World Health Organization reference values (2001) were used to estimate the prevalence of iron sufficiency and anemia. The overall prevalence of anemia was low in the 2009-to-2011 period--97% of Canadians had sufficient hemoglobin levels. Generally, hemoglobin concentration increased compared with 1970-1972; however, at ages 65 to 79, rates of anemia were higher than in 1970-1972. Depleted iron stores were found in 13% of females aged 12 to 19 and 9% of females aged 20 to 49. Lower household income was associated with a lower prevalence of hemoglobin sufficiency, but was not related to lower serum ferritin sufficiency. Self-perceived health and diet were not significantly associated with hemoglobin and serum ferritin levels. The lack of a relationship between iron status and diet may be attributable to the use of questions about food consumption frequency that were not specifically designed to estimate dietary iron intake. Factors other than iron intake might have contributed to the increase in the prevalence of anemia among seniors.

    Sallaberger, Christian; Space Plan Task Force, Canadian Space Agency

    The Canadian Space Agency has chosen space robotics as one of its key niche areas, and is currently preparing to deliver the first flight elements for the main robotic system of the international space station. The Mobile Servicing System (MSS) is the Canadian contribution to the international space station. It consists of three main elements. The Space Station Remote Manipulator System (SSRMS) is a 7-metre, 7-dof, robotic arm. The Special Purpose Dextrous Manipulator (SPDM), a smaller 2-metre, 7-dof, robotic arm can be used independently, or attached to the end of the SSRMS. The Mobile Base System (MBS) will be used as a support platform and will also provide power and data links for both the SSRMS and the SPDM. A Space Vision System (SVS) has been tested on Shuttle flights, and is being further developed to enhance the autonomous capabilities of the MSS. The CSA also has a Strategic Technologies in Automation and Robotics Program which is developing new technologies to fulfill future robotic space mission needs. This program is currently developing in industry technological capabilities in the areas of automation of operations, autonomous robotics, vision systems, trajectory planning and object avoidance, tactile and proximity sensors, and ground control of space robots. Within the CSA, a robotic testbed and several research programs are also advancing technologies such as haptic devices, control via head-mounted displays, predictive and preview displays, and the dynamic characterization of robotic arms. Canada is also now developing its next Long Term Space Plan. In this context, a planetary exploration program is being considered, which would utilize Canadian space robotic technologies in this new arena.

    This study identified and described Canadians' self-perceived eating habits and food skills through the use of population-based data. Data from the Canadian Community Health Survey 2013 Rapid Response on Food Skills was used to examine the eating quality and patterns of Canadians. Data were collected from all provinces in January and February 2013. Respondent variables (sex, age, Aboriginal/immigrant status) were examined to assess differentiations between socio-demographic groupings (family structure, marital status, education, and income). Logistic regression was used to determine whether demographic variables increased the likelihood of certain responses. Forty-six percent of Canadians believe they have excellent/very good eating habits, with 51% categorizing their habits as good or fair. Similarly, the majority report having good food skills. Sex and age were significantly associated with food skills, with women rating their cooking skill proficiency higher than men (72% vs 55%), and older Canadians reporting higher food skill knowledge than their younger counterparts. Results indicate that while portions of the Canadian population have adequate food skills, others are lacking, which may negatively impact their diet. Findings from this study have implications for education and health promotion programs focusing on foods skills, particularly among vulnerable target groups.

  20. Multi-year objective analyses of warm season ground-level ozone and PM2.5 over North America using real-time observations and Canadian operational air quality models

    Science.gov (United States)

    Robichaud, A.; Ménard, R.

    2014-02-01

    Multi-year objective analyses (OA) on a high spatiotemporal resolution for the warm season period (1 May to 31 October) for ground-level ozone and for fine particulate matter (diameter less than 2.5 microns (PM2.5)) are presented. The OA used in this study combines model outputs from the Canadian air quality forecast suite with US and Canadian observations from various air quality surface monitoring networks. The analyses are based on an optimal interpolation (OI) with capabilities for adaptive error statistics for ozone and PM2.5 and an explicit bias correction scheme for the PM2.5 analyses. The estimation of error statistics has been computed using a modified version of the Hollingsworth-Lönnberg (H-L) method. The error statistics are "tuned" using a χ2 (chi-square) diagnostic, a semi-empirical procedure that provides significantly better verification than without tuning. Successful cross-validation experiments were performed with an OA setup using 90% of data observations to build the objective analyses and with the remainder left out as an independent set of data for verification purposes. Furthermore, comparisons with other external sources of information (global models and PM2.5 satellite surface-derived or ground-based measurements) show reasonable agreement. The multi-year analyses obtained provide relatively high precision with an absolute yearly averaged systematic error of less than 0.6 ppbv (parts per billion by volume) and 0.7 μg m-3 (micrograms per cubic meter) for ozone and PM2.5, respectively, and a random error generally less than 9 ppbv for ozone and under 12 μg m-3 for PM2.5. This paper focuses on two applications: (1) presenting long-term averages of OA and analysis increments as a form of summer climatology; and (2) analyzing long-term (decadal) trends and inter-annual fluctuations using OA outputs. The results show that high percentiles of ozone and PM2.5 were both following a general decreasing trend in North America, with the eastern

    White matter disease occurs as a consequence of small vessel disease; however, hypoperfusion may also play a role. We investigated whether patients with less cerebral vessel anastomosis may develop more white matter disease. Magnetic resonance imaging (1.5t) with intracranial magnetic resonance angiography data was collected on a convenience sample between July 2008 and January 2009. All patients were independently assessed for circle of Willis variants by two researchers and categorized into two groups: those with a complete circle of Willis and those with an incomplete circle of Willis (absent vessels). The complete group was sub-divided into a classical group (entirely normal circle of Willis) and a hypoplastic group (hypoplasia but no absent vessels). White matter disease assessment was conducted for these groups, by two researchers blind to magnetic resonance angiography findings, on all patients over 50 years old. The circle of Willis was characterized in 163 patients, while 90 (>50 years) underwent white matter disease assessment. The kappa inter-rater reliability between both circle of Willis assessors and between both white matter disease assessors was 0.57 and 0.63, respectively. The prevalence of circle of Willis variants strongly correlated with the seminal paper by Riggs and Rupp. Independent of age and gender, those with an incomplete circle of Willis (n = 68) exhibited 58% more white matter disease than those with a complete circle of Willis (n = 22) (white matter disease score 6.52 vs. 4.11, respectively, P = 0.03). Patients with absent anterior vessels exhibited more frontal white matter disease than those with intact anterior vessels (3.7 vs. 1.72, P < 0.001). Patients with absent posterior vessels exhibited more occipital white matter disease than those with intact posterior vessels (2.52 vs. 1.34, P = 0.014). These data suggest that congenital absence of anastomotic capacity correlates with incident white matter disease, thus

    2016-01-01

    Cannabis has been widely used as a medicinal agent in Eastern medicine with earliest evidence in ancient Chinese practice dating back to 2700 BC. Over time, the use of medical cannabis has been increasingly adopted by Western medicine and is thus a rapidly emerging field that all pain physicians need to be aware of. Several randomized controlled trials have shown a significant and dose-dependent relationship between neuropathic pain relief and tetrahydrocannabinol - the principal psychoactive component of cannabis. Despite this, barriers exist to use from both the patient perspective (cost, addiction, social stigma, lack of understanding regarding safe administration) and the physician perspective (credibility, criminality, clinical evidence, patient addiction, and policy from the governing medical colleges). This review addresses these barriers and draws attention to key concerns in the Canadian medical system, providing updated treatment approaches to help clinicians work with their patients in achieving adequate pain control, reduced narcotic medication use, and enhanced quality of life. This review also includes case studies demonstrating the use of medical marijuana by patients with neuropathic low-back pain, neuropathic pain in fibromyalgia, and neuropathic pain in multiple sclerosis. While significant preclinical data have demonstrated the potential therapeutic benefits of cannabis for treating pain in osteoarthritis, rheumatoid arthritis, fibromyalgia, and cancer, further studies are needed with randomized controlled trials and larger study populations to identify the specific strains and concentrations that will work best with selected cohorts.

    Circles of Support aim to enable people with learning disabilities (and others) to live full lives as part of their communities. As part of a wider study of the economic case for community capacity building conducted from 2012 to 2014, we conducted a mixed methods study of five Circles in North West England. Members of these Circles were supporting adults with moderate to profound learning disabilities and provided accounts of success in enabling the core member to live more independent lives with improved social care outcomes within cost envelopes that appeared to be less than more traditional types of support. The Circles also reported success in harnessing community resources to promote social inclusion and improve well-being. This very small-scale study can only offer tentative evidence but does appear to justify more rigorous research into the potential of Circles to secure cost-effective means of providing support to people with learning disabilities than the alternative, which in most cases would have been a long-term residential care placement. © The Author(s) 2016.

    Full Text Available Restorative Practices (RP in schools is a new and emerging field. Meeting in Circles to build friendships, develop emotional literacy skills, resolve conflict, or learn interactively are some of the core components of these programs. This article describes a 2-year study of 12 weekly Talking Circles organized under the auspices of a RP program in an urban high school with 60 adolescent girls. Primary data sources included 257 hr of participant observations in Talking Circles and individual, semi-structured interviews with 31 students. The Relational Cultural model, rooted in the work of Jean Baker Miller, served as the conceptual framework for understanding teens’ interactions within the Circle’s unique set of social conditions in a school environment. Findings demonstrated that Talking Circles provided a safe space for peers helping peers, and that the girls improved their listening, anger management, and empathic skills, which led to greater self-efficacy. It appears that Talking Circles could provide another venue for developing social-emotional literacy skills and growth-fostering relationships in schools.

  5. Circle Detection Using an Electromagnetism-Inspired Algorithm

    2011-10-01

    Full Text Available The Physic-inspired computation is becoming popular and has been acknowledged by the scientific community. This emerging area has developed a wide range of techniques and methods for dealing with complex problems. On the other hand, automatic circle detection in digital images has been considered as an important and complex task for the computer vision community that has devoted a tremendous amount of research seeking for an optimal circle detector. This article presents an algorithm for the automatic detection of circular shapes embedded into complicated and noisy images with no consideration of the conventional Hough transform techniques. The approach is based on a nature-inspired technique called the Electromagnetism- Like Optimization (EMO which is a heuristic method following electromagnetism principles for solving complex optimization problems. For the EMO algorithm, solutions are built considering the electromagnetic attraction and repulsion among charged particles with a charge representing the fitness solution for each particle. The algorithm uses the encoding of three non-collinear points as candidate circles over an edge-only image. Guided by the values of the objective function, the set of encoded candidate circles (charged particles are evolved using the EMO algorithm so that they can fit into the actual circles on the edge map of the image. Experimental results from several tests on synthetic and natural images with a varying range of complexity are included to validate the efficiency of the proposed technique regarding accuracy, speed, and robustness.

    Continuity is an important aspect of quality of care, especially for complex patients in the community. We explored provider perceptions of continuity through a system's lens. The circle of care was used as the system. Soft systems methodology was used to understand and improve continuity for end of life patients in two communities. Physicians, nurses, pharmacists in two communities in British Columbia, involved in end of life care. Two debates/discussion groups were completed after the interviews and initial analysis to confirm findings. Interview recordings were qualitatively analyzed to extract components and enablers of continuity. 32 provider interviews were completed. Findings from this study support the three types of continuity described by Haggerty and Reid (information, management, and relationship continuity). This work extends their model by adding features of the circle of care that influence and enable continuity: Provider Connectedness the sense of knowing and trust between providers who share care of a patient; a set of ten communication patterns that are used to support continuity across the circle of care; and environmental factors outside the circle that can indirectly influence continuity. We present an extended model of continuity of care. The components in the model can support health planners consider how health care is organized to promote continuity and by researchers when considering future continuity research.

    In this paper we present a method of reconstructing the circle parameters from a set of datapoints on a plane. The method is based on the geometrical Legendre transform. We test the method under various scenarios using Monte Carlo generated data. These scenarios include variation of the noise hits percentage, uncertainties in the hit position and the number of datapoints. The technique is proven to be robust and provide quickly and effciently very accurate results. Furthermore, the use of the geometrical Legendre transform method for the identifcation of two overlapping circles is shown.

    During unilateral selective cerebral perfusion (uSCP), with right axillary artery or brachiocephalic trunk cannulation, the brain receives blood only via the right common carotid artery and right vertebral artery (VA). The left hemisphere is perfused mainly through the circle of Willis (CW). However, at least 50% of individuals have some variation in the CW. The aim of the present work was to study the variations in CW and VA that could have an impact on haemodynamics during uSCP. From May 2005 to March 2012, a total number of 250 circles obtained via routine dissection for medico-legal reasons were examined. The external diameters of all CW segments and both VAs were measured. From January 2008 to March 2012, a total number of 250 patients subjected to computed tomographic angiography of the CW were also examined. Nine evident configurations of the CW that could cause hypoperfusion during uSCP were observed. They were subdivided in to seven types, according to location and the number of major vessels at risk of hypoperfusion. Type IA: hypo/aplasia of left posterior communicating artery (PComA), found in 35.6% of cases; Type IB: hypo/aplasia of anterior communicating artery (AComA), found in 2% of cases; Type IIA: hypo/aplasia of both left PComA and AComA, found in 4.8% of cases; Type IIB: hypo/aplasia of precommunicating (P1) segment of left posterior cerebral artery or right VA, found in 9.2% of cases; Type IIIA: hypo/aplasia of precommunicating (A1) segment of right anterior cerebral artery, found in 6% of cases; Type IIIB: hypo/aplasia of both right VA and AComA, found in 0.2% of cases; Type IV: hypo/aplasia of both right A1 and right VA or both right A1 and left P1, found in 0.8% of cases. All types were present in 58.6% of all examined CWs. Our results show that CW variations are present in a significant number of patients. Our data support the need for extensive preoperative examination and meticulous intraoperative monitoring of cerebral perfusion during u

    Full Text Available Abstract Background The variations of the circle of Willis (CW are clinically important as patients with effective collateral circulations have a lower risk of transient ischemic attack and stroke than those with ineffective collaterals. The aim of the present cadaveric study was to investigate the anatomical variations of the CW and to compare the frequency of prevalence of the different variations with previous autopsy studies as variations in the anatomy of the CW as a whole have not been studied in the Indian subcontinent. Methods The external diameter of all the arteries forming the CW in 225 normal Sri Lankan adult cadaver brains was measured using a calibrated grid to determine the prevalence in the variation in CW. Chisquared tests and a correspondence analysis were performed to compare the relative frequencies of prevalence of anatomical variations in the CW across 6 studies of diverse ethnic populations. Results We report 15 types of variations of CW out of 22 types previously described and one additional type: hypoplastic precommunicating part of the anterior cerebral arteries (A1 and contralateral posterior communicating arteries (PcoA 5(2%. Statistically significant differences (p Conclusion The present study reveals that there are significant variations in the CW among intra and inter ethnic groups (Caucasian, African and Asian: Iran and Sri Lanka dominant populations, and warrants further studies keeping the methods of measurements, data assessment, and the definitions of hypoplasia the same.

    Canada's energy is complex and an important resource as it fuels and funds the economy. The unique character of Canada's energy production and consumption provides strength to the country. The purpose of this booklet was to highlight Canada's energy production and consumption and to demonstrate Canada's rank globally with other major global energy players. The document also presented information on the value of Canada's energy exports, Canada's relationship with the United States, and Canada's energy-related carbon dioxide emissions. Specifically, the document discussed Canada's energy in a global context; the value of Canada's energy exports; domestic value of energy; Canada's unique energy mix; Canada's electricity mix; Canada's carbon dioxide emissions; energy strategies; and the importance of energy to Canadians. It was concluded that there are 14 federal, provincial and territorial jurisdictions managing their respective energy resources. All of these regions, with the exception of Saskatchewan have produced an energy strategy document or a climate change action plan focusing on 8 areas of action, notably awareness; benefit; efficiency; development; diversification; electricity; and emissions. refs., tabs., figs.

    The Canadian Petroleum Products Institute (CPPI) is an association of Canadian companies involved in the downstream sector of the petroleum industry which includes refining, distributing and marketing of petroleum products. CPPI`s mandate includes: (1) establishing environmental policies, (2) establishing working relationships with governments to develop public policy, (3) developing guidelines for the safe handling of petroleum products, and (4) providing information about the petroleum industry to the public. Canada`s 19 refineries processed an average of 1.5 million barrels of crude oil per day in 1996. Domestic sources of crude made up 61 per cent of crude oil processed in 1996. Total exports during the year amounted to 105 million barrels. Some of the issues that the CPPI focused on during 1996 included the controversy over the future of the octane enhancing fuel additive MMT, fuel quality standards for transportation fuels and reformulated fuels, gasoline pricing, air quality and workplace safety. CPPI members` participation in the Voluntary Challenge and Registry (VCR) program towards reducing greenhouse gas emissions was also discussed. The industry was also actively involved in seeking to improve its refinery wastewater discharges.

    Ivanov, Dmitry; Dol, Alexander; Pavlova, Olga; Aristambekova, Asel

    2014-01-01

    This paper includes results of the first stage of research aimed at the development of recommendations for physicians in order to help them to choose a particular type of cerebral arteries aneurysms treatment. Recent studies show that the majority of aneurysms develop as a result of hemodynamic and degenerative lesions of the vascular wall. Obviously, such wall damage can be studied using the methods of continuum mechanics and numerical simulations. Biomechanical modelling allows us to study hemodynamic parameters and stress-strain state of these arteries in health and disease, and to formulate practical recommendations for the necessity and reasonable selection of a particular type of cerebral arteries aneurysm treatment. At this stage the realistic geometric models of arterial circle of Willis were built for its normal state and in the presence of aneurysms. The ultrasound analysis of circle of Willis was conducted in order to obtain blood flow parameters and the boundary conditions for carotid and vertebral arteries. Also, the mechanical properties of these arteries were investigated and constants of the Mooney-Rivlin strain energy function were obtained. Thus, the boundary problem describing the behaviour of human Willis circle arteries was stated. Further, this problem will be solved numerically using the finite element method. The numerical results will be analyzed from the point of view of the influence of the mechanical factors on the emergence, growth and rupture of circle of Willis aneurysms.

  18. Circle (CO2 reabsorbing) breathing systems: Human applications.

    Science.gov (United States)

    Magee, Patrick

    2017-07-01

    Artificial breathing systems to help humans survive extreme environments are used over a range of ambient pressures, using various gases of different volumetric concentrations. These activities include anaesthesia and intensive care activity, high-altitude mountaineering, firefighting, aerospace extravehicular space activity and underwater diving operations. A circle breathing system is one in which the exhaled carbon dioxide is absorbed by an alkali substance and the remaining unused gases are recirculated, usually for the sake of economy and environment. This allows the flow of the fresh gas to be considerably reduced, thereby saving on fresh-gas supply. Circle systems are often used in the circumstances cited above, although not always at low fresh-gas flows. The circle system used in anaesthesia and intensive care has the least engineering demands made on it, although it is used on patients who are highly vulnerable; it usually provides a mixture of air and oxygen, and perhaps a breathable anaesthetic gas, all at sea-level pressure. Mountaineering and firefighting applications involve an extreme earthbound environment, with the user undergoing extreme physical work. The astronaut's spacesuit and life support system contains a high-flow circle system, the breathing gases themselves pressurising the suit as well as providing respiratory life support and thermal comfort; the gas provided is pure oxygen at about a third of sea-level atmosphere. There are numerous varieties of breathing systems for diving, including a circle system, often for clandestine naval activity; the gases used are a combination of oxygen, nitrogen and helium, to minimise the possibility of decompression sickness, nitrogen narcosis and oxygen toxicity and must be provided at a varying pressure and concentration appropriate to depth.

  19. Going Full Circle With Teacher Feedback

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Research on the evaluation of early childhood programs focuses mainly on its outcomes rather than its process with often little attention given to the role that feedback to teachers in pre-kindergarten (pre-k programs plays in the larger cycle of the evaluation process. This article provides a case example of a multiyear evaluation of community-based pre-k programs serving about 360 three- and four-year old children over a 5-year period in the District of Columbia. The Closing the Loop Evaluation Model proposed represents a responsive evaluation approach that illustrates the interconnected interactions between teacher feedback during the evaluation process and two supporting evaluation methodologies that emphasize social justice and utility. Findings from the case example highlight the responsive evaluation approach, feedback process, and ensuing conceptual and instrumental changes that occurred among stakeholders from whole-group feedback to small-group “report card” meetings with add-ons such as technical assistance, teacher-generated action plans, and teacher follow-up and feedback to close the evaluation loop. The authors discuss lessons learned about the evaluation process from the case example around aspects of feedback, including timing, audience, and function. Findings highlight the importance of feedback being timely and prompt, high quality in focus and content, non-punitive, collaborative, concise, and useful. The authors conclude that an evaluation process that includes teacher feedback, couched in social justice and utility, can have positive outcomes for all stakeholders and will likely lead to higher quality early childhood education programs.

  2. Canadian synthetic resins industry

    Energy Technology Data Exchange (ETDEWEB)

    Margeson, J. [Industry Canada, Ottawa, ON (Canada)

    2000-06-01

    The growth of the synthetic resin industry in Canada is described. In 1999 the industry had shipments totalling $6.3 billion and employed about 9,000 people in 105 establishments. The industry is concentrated in Alberta, Ontario and Quebec. Plants in Alberta produce commodity-grade thermoplastic resins from raw materials derived mainly from natural gas, whereas plants in Ontario and Quebec produce both thermoplastic and thermoset resins using raw materials derived from both crude oil and natural gas. Sixty-four per cent of the synthetic reins produced in Canada, worth about $4.1 billion, are exported. This is offset by imports of 68 per cent of domestic consumption, (valued at $5.0 billion) reflecting rationalization and specialization of the resin industry on a continental basis. Process and product technologies used in Canada are up-to-date and licensed from parent or other foreign chemical companies. Capital investment in the Canadian resin industry is lagging behind investment in the United States, however, this is expected to change once the impact of recent investments in the industry in Alberta is reflected in the statistics. A five to seven per cent real average annual growth in world-wide consumption is predicted over the next five years. Growth in North America is projected to be in the three to four per cent range. The Alberta-based component of the industry, being relatively new, is expected to improve its ability to compete globally in commodity thermoplastics. In contrast, the plants in Ontario and Quebec suffer from the fact that they were built prior to the Free Trade Agreement and were designed to satisfy domestic requirements. They are attempting to compensate for their lack of economics of scale by developing strategies to supply niche products. 8 figs.

    Background Physical therapy can improve motor function in patients with PD. Music performance may be used to improve motor skills by rhythmic entrainment. Drumming has long been a part of traditional healing rituals worldwide, and is increasingly being utilized as a therapeutic strategy. Methods This pilot controlled prospective cohort trial assessed feasibility and effects of twice-weekly group West African drum circle classes for 6 weeks on PD patients’ quality of life, symptoms, motor findings, cognition, and mood. Ten patients with PD were recruited into the drum circle group. Ten patients with PD were matched pairwise to each of the drum circle participants, and enrolled in a no-intervention control group. Both groups completed the PD-specific Parkinson Disease Questionnaire (PDQ)-39 quality of life assessment and the Geriatric Depression Scale (GDS), and underwent motor and cognitive assessments by a rater blinded to group at baseline, 6 weeks, and 12 weeks. Results Drummers had significantly improved PDQ-39 scores from baseline to 6 weeks (−5.8, p=0.042), whereas the control group's scores were unchanged. Walking performance was significantly faster at baseline for controls; after 6 weeks of drumming this difference was no longer significant, and remained non-significant at 12 weeks. The drummers trended (p=0.069) toward improvement in walking from baseline to 12 weeks. Other outcomes did not significantly change from baseline to 6 or 12 weeks. Conclusions Drum circle classes significantly and reversibly improved quality of life in patients with PD. This pilot trial's findings merit larger controlled investigations comparing drumming classes to established interventions in PD, such as physical therapy. PMID:27340683

  5. Are Namibian "fairy circles" the consequence of self-organizing spatial vegetation patterning?

    Directory of Open Access Journals (Sweden)

    Michael D Cramer

    Full Text Available Causes of over-dispersed barren "fairy circles" that are often surrounded by ca. 0.5 m tall peripheral grasses in a matrix of shorter (ca. 0.2 m tall grasses in Namibian grasslands remain mysterious. It was hypothesized that the fairy circles are the consequence of self-organizing spatial vegetation patterning arising from resource competition and facilitation. We examined the edaphic properties of fairy circles and variation in fairy circle size, density and landscape occupancy (% land surface with edaphic properties and water availability at a local scale (<50 km and with climate and vegetation characteristics at a regional scale. Soil moisture in the barren fairy circles declines from the center towards the periphery and is inversely correlated with soil organic carbon, possibly indicating that the peripheral grass roots access soil moisture that persists into the dry season within fairy circles. Fairy circle landscape occupancy is negatively correlated with precipitation and soil [N], consistent with fairy circles being the product of resource-competition. Regional fairy circle presence/absence is highly predictable using an empirical model that includes narrow ranges of vegetation biomass, precipitation and temperature seasonality as predictor variables, indicating that fairy circles are likely a climate-dependent emergent phenomenon. This dependence of fairy circle occurrence on climate explains why fairy circles in some locations may appear and disappear over time. Fairy circles are only over-dispersed at high landscape occupancies, indicating that inter-circle competition may determine their spacing. We conclude that fairy circles are likely to be an emergent arid-grassland phenomenon that forms as a consequence of peripheral grass resource-competition and that the consequent barren circle may provide a resource-reservoir essential for the survival of the larger peripheral grasses and provides a habitat for fossicking fauna.

  6. Roundness deviation evaluation method based on statistical analysis of local least square circles

    Science.gov (United States)

    Zhi-min, Cao; Yun, Wu; Jian, Han

    2017-10-01

    Today, the quantitative evaluation of the quality of circular or cylindrical workpieces is becoming increasingly important for the relevant industrial production sectors. Although there are already some roundness deviation evaluation algorithms available to accomplish this task, these methods are always done in a holistic way. In many industrial scenarios, however, fine evaluation of the roundness variation of local segments is often more practical than the global assessment. By performing a fine evaluation of roundness variation of local segments, crucial information that can reveal intrinsic quality characteristics of both the workpiece and the production machine can be retrieved. However, this important issue has not been well studied. To deal with this problem, a roundness deviation evaluation method based on statistical analysis of local least square circles was proposed. Experimental results illustrated that the proposed method can stably and reliably evaluate the local and global roundness deviations effectively.

    Circle contact lenses, also known as color contact lenses and big eye contact lenses, are a type of cosmetic contact lens. It is not generally known that a circle contact lens usually contains iron oxide and other metals, which means their use during magnetic resonance imaging (MRI) is a potential hazard. We present a rare case of incidental discovery of circle contact lenses by MRI and MRI images of circle lenses in vitro. Circle contact lenses usually contain iron oxide, which is a known source of susceptibility artifact on MRI. Not only radiologists and radiographers but also referring physicians should be familiar with the imaging findings and potential risk of scanning circle contact lenses by MRI.

    Objectives To assess whether the core symptoms of Alzheimer’s disease (AD) consistently predict patient self-rated quality of life (QOL) as assessed by a variety of QOL measures in a large national sample of AD patients. Design Cross-sectional. Setting Fifteen dementia and geriatric clinics across Canada. Participants Community-living patients with AD (n = 370) with Mini-Mental State Examination (MMSE) scores > 10. Measurements Patients rated their QOL using two utility indexes, the EQ-5D, the Quality of Well-Being Scale, a global QOL visual analogue scale, and the disease-specific QOL-AD instrument. Cognition was assessed with the AD Assessment Scale-Cognitive subscale and MMSE, function with the Disability Assessment for Dementia, and behavioral and psychological symptoms with the Neuropsychiatric Inventory (NPI) and the Geriatric Depression Scale (GDS). One-way analysis of variance and fully adjusted multiple linear regression were used to assess the relationship between core dementia symptoms and QOL ratings. Results The QOL measures had only small to moderate correlations with each other. For all QOL measures, patient ratings were significantly lower among patients with more depressive symptoms. In multivariable analyses, the GDS score was the only significant independent predictor of patient self-ratings for all four QOL measures. Conclusions Self-rated symptoms of depression were a consistent independent predictor of patient-rated QOL across diverse QOL measures, while performance-based measures of cognition and informant-based functional status were not. These findings confirm the importance of identifying and treating depression in patients with AD and endorse the use of measures of self-rated depressive symptoms and QOL as outcomes in AD clinical trials.

  18. Outer Circle Versus Inner Circle: Special Considerations While Rejuvenating an Indian Face Using Fillers.

    Shetty, Rashmi

    2015-01-01

    An oval face, pronounced cheek bones, a defined jaw line and a smooth Ogee curve are global aesthetic beauty goals. Though criteria are similar the Indian face poses some unique challenges because of the innate differences in skeletal shape, size, and soft tissue disposition. Width of the malar prominences and mandibular angles along with height are smaller compared to the other Asian and Caucasian populations along with a much heavier soft tissue disposition. This creates unique deficits and places unique demands on aesthetic intervention. The evolution of practice patterns has lead to a variety of newer approaches; however, it is still common to target the nasolabial and mid-face volumizing as basic intervention for facial beautifying and rejuvenation. As aging progresses, Indian faces tend to get fuller and the tissue then descends downwards similar to other ethnic groups albeit more aggressive due to higher volumes of facial fat pad and smaller bone framework. Any excess correction in the inner circle zones will further add to the bulk along with cumulative remnants of previously administered fillers. In a younger face when the goal is beautification the attempt is to address the specific structural deficit on the outer bony framework along with the chin. This enhances the appearance immediately as well as holds up the tissue descent as they age. When the goal is youthful transition of an aging face, then again the bony changes further enhance the deficit in framework and the loss of fat pads along the periphery that is lateral forehead, temples and lateral cheek. Fat pad correction will give the most natural and best results as against working on the anterior mid cheek, nasolabials and angle of the mouth in a soft tissue heavy center zone of the face. Botulinum toxin and hyaluronic acid (HA) fillers remain the most popular facial injectables used for facial rejuvenation and structural enhancement.

    Tang, Sha; Hyman, Bradley C

    2005-06-01

    To enable investigation of nematode mitochondrial DNA evolution, methodology has been developed to amplify intact nematode mitochondrial genomes in preparative yields using a rolling circle replication strategy. Successful reactions were generated from whole cell template DNA prepared by alkaline lysis of the rhabditid nematode Caenorhabditis elegans and a mermithid nematode, Thaumamermis cosgrovei. These taxa, representing the two major nematode classes Chromodorea and Enoplea, maintain mitochondrial genomes of 13.8 kb and 20.0 kb, respectively. Efficient amplifications were conducted on template DNA isolated from individual or pooled nematodes that were alive or stored at -80 degrees C. Unexpectedly, these experiments revealed that multiple T. cosgrovei mitochondrial DNA haplotypes are maintained in our local population. Rolling circle amplification products can be used as templates for standard PCR reactions with specific primers that target mitochondrial genes or for direct DNA sequencing.

    The authors analyze the residuals Δα cos δ and Δδ obtained in the reduction of star observations made with the axial meridian circle of the Main Astronomical Observatory, National Academy of Sciences of Ukraine. The mean autocorrelation functions, variances, and spectra are given. The averaging allowed for the bias of sample functions for finite measurement runs. The spectra expressed in [open square]″Hz are fitted by the two-component models g(f) = 563(T0f)-2.2+7.0 and g(f) = 242(T0f)-1.5+5.1 for right ascension and declination residuals, respectively, with T0 = 18000 s. The data are compared with those for the Bordeaux meridian circle of the classical type. The spectral low-frequency component is shown to be produced by thermal deformations of the instrument tube.

    Rolling circle amplification (RCA) has been useful for detecting point mutations in isolated nucleic acids, but its application in cytological preparations has been problematic. By pretreating cells with a combination of restriction enzymes and exonucleases, we demonstrate RCA in solution and in situ to detect gene copy number and single base mutations. It can also detect and quantify transcribed RNA in individual cells, making it a versatile tool for cell-based assays.

    New position uncertainty (delocalization) measures for a particle on the circle are proposed and illustrated in several examples, where the previous measures (based on 2{pi}-periodic position operators) appear to be unsatisfactory. The new measures are suitably constructed using the standard multiplication angle operator variances. They are shown to depend solely on the state of the particle and to obey uncertainty relations of the Schroedinger-Robertson type.

    Dark circles around the eyes are a complex issue with two main possible causes, the accumulation of melanin in the skin around the eyes and the accumulation of heme resulting from blood leakage. The free heme produced in this manner is highly cytotoxic, proinflammatory and pro-oxidative. To evaluate the effect of Fucus extract on heme oxygenase-1 (HO-1) stimulation activity, and to study its in vitro anti-inflammatory, antioxidative, and collagen stimulation activity. The HO-1 stimulation activity was first evaluated at gene level by reverse transcriptase- polymerase chain reaction targeting specific HO-1 gene, and then followed by Western blot in protein level. The in vitro anti-inflammatory effect was measured by quantification of interleukin-8 (IL-8) level. The in vitro antioxidative activity was measured. Collagen stimulation activity was quantitatively measured by the amount of deposited collagen I in the extracellular matrix. Fucus extract was identified to have HO-1 stimulation activity at both gene and protein level. By stimulating this enzyme, it promotes the degradation of toxic heme to its protective catabolites (CO, Ferritin, and bilirubin) and reduces the source of dark circles. In addition, Fucus extract showed good anti-inflammatory efficacy. The strong antioxidation property of Fucus extract can reduce eye bags and wrinkles while its collagen boosting activity will potentially reduce fine lines and wrinkles. Fucus extract is a novel product that brings a quadruple approach to the treatment of under-eye dark circles.

    Blood flow through a vessel depends upon compliance and resistance. Resistance changes dynamically due to vasoconstriction and vasodilation as a result of metabolic activity, thus allowing for more or less flow to a particular area. The structure responsible for directing blood to the different areas of the brain and supplying the increase flow is the cerebral arterial circle (CAC). A series of 1D equations were utilized to model propagating flow and pressure waves from the left ventricle of the heart to the CAC. The focus of the current research was to understand the collateral capability of the circle. This was done by decreasing the peripheral resistance in each of the efferent arteries, up to 10% both unilaterally and bilaterally. The collateral patterns were then analyzed. After the initial 60 simulations, it became apparent that flow could increase beyond the scope of a 10% reduction and still be within in vivo conditions. Simulations with higher percentage decreases were performed such that the same amount of flow increase would be induced through each of the efferent arteries separately, same flow tests (SFTs), as well as those that were found to allow for the maximum flow increase through the stimulated artery, maximum flow tests (MFTs). The collateral pattern depended upon which efferent artery was stimulation and if the stimulation was unilaterally or bilaterally induced. With the same amount of flow increase through each of the efferent arteries, the MCAs (middle cerebral arteries) had the largest impact on the collateral capability of the circle, both unilaterally and bilaterally.

  12. Host RNA circles and the origin of hepatitis delta virus.

    2014-03-21

    Recent reports show that many cellular RNAs are processed to form circular species that are relatively abundant and resistant to host nucleases. In some cases, such circles actually bind host microRNAs. Such depletion of available microRNAs appears to have biological roles; for instance, in homeostasis and disease. These findings regarding host RNA circles support a speculative reappraisal of the origin and mode of replication of hepatitis delta virus, hepatitis delta virus (HDV), an agent with a small circular RNA genome; specifically, it is proposed that in hepatocytes infected with hepatitis B virus (HBV), some viral RNA species are processed to circular forms, which by a series of chance events lead to an RNA that can be both replicated by host enzymes and assembled, using HBV envelope proteins, to form particles some of which are infectious. Such a model also may provide some new insights into the potential pathogenic potential of HDV infections. In return, new insights into HDV might provide information leading to a better understanding of the roles of the host RNA circles.

    Full Text Available Background. The United Kingdom Global Rating Scale (GRS-UK measures unit-level quality metrics processes in digestive endoscopy. We evaluated the psychometric properties of its Canadian version (GRS-C, endorsed by the Canadian Association of Gastroenterology (CAG. Methods. Prospective data collection at three Canadian endoscopy units assessed GRS-C validity, reliability, and responsiveness to change according to responses provided by physicians, endoscopy nurses, and administrative personnel. These responses were compared to national CAG endoscopic quality guidelines and GRS-UK statements. Results. Most respondents identified the overarching theme each GRS-C item targeted, confirming face validity. Content validity was suggested as 18 out of 23 key CAG endoscopic quality indicators (78%, 95% CI: 56–93% were addressed in the GRS-C; statements not included pertained to educational programs and competency monitoring. Concordance ranged 75–100% comparing GRS-C and GRS-UK ratings. Test-retest reliability Kappa scores ranged 0.60–0.83, while responsiveness to change scores at 6 months after intervention implementations were greater (P<0.001 in two out of three units. Conclusion. The GRS-C exhibits satisfactory metrics, supporting its use in a national quality initiative aimed at improving processes in endoscopy units. Data collection from more units and linking to actual patient outcomes are required to ensure that GRS-C implementation facilitates improved patient care.

    Values are desirable, trans-situational goals, varying in importance, that guide behavior. Research has demonstrated that universal values may alter in importance as a result of major life events. The present study examines the effect of spaceflight and the demands of astronauts' job position as life circumstances that affect value priorities. We employed thematic content analysis for references to Schwartz's well-established value markers in narratives (media interviews, journals, and pre-flight interviews) of seven Canadian astronauts and compared the results to the values of National Aeronautics and Space Administration (NASA) and Russian Space Agency (RKA) astronauts. Space flight did alter the level of importance of Canadian astronauts' values. We found a U-shaped pattern for the values of Achievement and Tradition before, during, and after flight, and a linear decrease in the value of Stimulation. The most frequently mentioned values were Achievement, Universalism, Security, and Self-Direction. Achievement and Self Direction are also within the top 4 values of all other astronauts; however, Universalism was significantly higher among the Canadian astronauts. Within the value hierarchy of Canadian astronauts, Security was the third most frequently mentioned value, while it is in seventh place for all other astronauts. Interestingly, the most often mentioned value marker (sub-category) in this category was Patriotism. The findings have important implications in understanding multi-national crew relations during training, flight, and reintegration into society.

    Climate change poses numerous risks to the health of Canadians. Extreme weather events, poor air quality, and food insecurity in northern regions are likely to increase along with the increasing incidence and range of infectious diseases. In this study we identify and characterize Canadian federal, provincial, territorial and municipal adaptation to these health risks based on publically available information. Federal health adaptation initiatives emphasize capacity building and gathering information to address general health, infectious disease and heat-related risks. Provincial and territorial adaptation is varied. Quebec is a leader in climate change adaptation, having a notably higher number of adaptation initiatives reported, addressing almost all risks posed by climate change in the province, and having implemented various adaptation types. Meanwhile, all other Canadian provinces and territories are in the early stages of health adaptation. Based on publically available information, reported adaptation also varies greatly by municipality. The six sampled Canadian regional health authorities (or equivalent) are not reporting any adaptation initiatives. We also find little relationship between the number of initiatives reported in the six sampled municipalities and their provinces, suggesting that municipalities are adapting (or not adapting) autonomously.

Three hundred twenty-four high-performance athletes (114 males and 201 females; mean age 21.3 +/- 13 years) from 8 Canadian sport centers participated in the study. Subjects prospectively completed 3-day dietary records, reporting all food, fluid, and supplement consumption. Dietary records were analyzed for total calories, macronutrients, and micronutrients for food alone and food plus supplements for all subjects collectively and according to gender and competitive event. Average daily energy intake was 2533 +/- 843 Kcal/day with males consuming more calories than females (2918 +/- 927 and 2304 +/- 713 Kcal/day, respectively; P Supplementation significantly increased athletes' energy, total carbohydrate, protein, and fat intake. Of 17 micronutrients assessed, intake ranged between 120% and 366% of recommended daily intake with food alone and between 134% to 680% of recommended daily intake with supplements. Canadian high-performance athletes do not consume adequate energy or carbohydrates. However, their intake of micronutrients exceed current recommended daily intakes, even when supplements are not considered, indicating that athletes make high-quality food choices. Supplementation significantly increased energy, macronutrient, and micronutrient intake.

    We propose an extension of the great circle cell count streamer finding method of Johnston et al. that can be applied to the future Gaia data base. The original method looks for streamers along great circles in the sky, our extension adds the kinematical restriction that velocity vectors should also be constrained to lie along these great circles, as seen by a Galactocentric observer. We show how to use these combined criteria starting from heliocentric observables. We test it by using the mock Gaia catalogue of Brown et al., which includes a realistic Galactic background and observational errors, but with the addition of detailed star formation histories for the simulated satellites. We investigate its success rate as a function of initial satellite luminosity, star formation history and orbit. We find that the inclusion of the kinematical restriction vastly enhances the contrast between a streamer and the background, even in the presence of observational errors, provided we use only data with good astrometric quality (fractional errors of 30 per cent or better). The global nature of the method diminishes the erasing effect of phase mixing and permits the recovery of merger events of reasonable dynamical age. Satellites with a star formation history different to that of the Galactic background are also better isolated. We find that satellites in the range of 108-109 L⊙ can be recovered even for events as old as ˜10 Gyr. Even satellites with 4-5 × 107 L⊙ can be recovered for certain combinations of dynamical ages and orbits.

    2012-06-01

    Full Text Available Research over the past two decades has amply demonstrated the importance of literature to the formation of both regional and national cultural identity, particularly in the face of mass market globalization of children’s book publishing in the 21st century as well as the predominance of non-Canadian content from television, movies, books, magazines and internet media. However, Canadian children appear to have only very limited exposure to Canadian authors and illustrators. In Atlantic Canada, regional Atlantic Canadian authors and illustrators for children receive very limited critical attention, and resources for the study and teaching of Atlantic Canadian children’s literature are few. Print and digital information sources on regional children’s books, publishing, authors and illustrators are scattered and inconsistent in quality and currency. This research project directly addresses these key concerns by summarizing the findings of a survey of Atlantic Canadian teachers on their use of regional books. In response to survey findings, the paper concludes by describing the creation of the Sea Stacks Project an authoritative web-delivered information resource devoted to contemporary Atlantic Canadian literature for children and teens.

    Canada supports international safeguards as a means by which the proliferation of nuclear weapons can be discouraged. Canada recognizes that,to meet that the IAEA must have effective safeguards techniques and the active cooperation of Member States. Therefore the Canadian Government decided in 1976 to initiate a program in support of IAEA safeguards, known as the Canadian Safeguards Support Program (CSSP). The CSSP is funded and administered by the Atomic Energy Control Board (AECB). The CSSP is a co-ordinated program for the development and the application of safeguards instruments and techniques for nuclear facilities and materials on behalf of the IAEA and also in support of Canada's own national nuclear material safeguards system, implemented by the AECB.

    The paper summarizes safeguards activities and programs undertaken in Canada. In 1970, Canada, in collaboration with the IAEA, began a study of procedures and equipment required for the application of safeguards to on-line-fueled reactors. In 1977, this assistance was substantially increased and formalized into the Canadian Safeguards Support Program (CSSP). To date, Canada has spent in excess of $35 million Canadian on this program. The CSSP provides support to the IAEA safeguards effort for areas in which Canada has expertise and has been primarily engaged in developing safeguards procedures and equipment for the CANDU power reactors in Canada and throughout the world. Work, projects, and equipment development undertaken by CANDU CSSP are highlighted.

    Prostate brachytherapy can be used as a monotherapy for low- and intermediate-risk patients or in combination with external beam radiation therapy (EBRT) as a form of dose escalation for selected intermediate- and high-risk patients. Prostate brachytherapy with either permanent implants (low dose rate [LDR]) or temporary implants (high dose rate [HDR]) is emerging as the most effective radiation treatment for prostate cancer. Several large Canadian brachytherapy programs were established in the mid- to late-1990s. Prostate brachytherapy is offered in British Columbia, Alberta, Manitoba, Ontario, Quebec and New Brunswick. We anticipate the need for brachytherapy services in Canada will significantly increase in the near future. In this review, we summarize brachytherapy programs across Canada, contemporary eligibility criteria for the procedure, toxicity and prostate-specific antigen recurrence free survival (PRFS), as published from Canadian institutions for both LDR and HDR brachytherapy.

    Mycetoma is a chronic granulomatous disease prevalent in tropical countries, but it also occurs in Europe and the United States. Early diagnosis is important as it has therapeutic implications. Although biopsy and microbiological culture provide the definitive diagnosis, these are difficult to achieve in many instances. The dot-in-circle sign is a recently proposed magnetic resonance imaging (MRI) sign of mycetoma, which is likely to be highly specific. We present a case of mycetoma of the thigh with characteristic MRI features. To the best of our knowledge, only 2 cases of mycetoma of the foot demonstrating this sign have been previously published.

  12. The Function of Love in Solzhenitsyn's The First Circle

    Directory of Open Access Journals (Sweden)

    John Schillinger

    1977-01-01

    Full Text Available Aleksander Solzhenitsyn, like Boris Pasternak before him, insists upon the primacy of life over any socio-political system. To lead truly meaningful lives, his characters must comprehend that they are responsible for their own actions; that they are engaged in an existential struggle which pits individual freedom against the will of authority. In The First Circle , this struggle is clearly reflected in the theme of love which, when analyzed in terms of the suppression or triumph of its four basic elements ( sex, eros, philia, and agape , offers a convincing allegory of man's existential self-definition by free choice.

    Rodrigues, Diego; Oakley, Ian

    Online social network services are increasingly popular web applications which display large amounts of rich multimedia content: contacts, status updates, photos and event information. Arguing that this quantity of information overwhelms conventional user interfaces, this paper presents Social Circles, a rich interactive visualization designed to support real world users of social network services in everyday tasks such as keeping up with friends and organizing their network. It achieves this by using 3D UIs, fluid animations and a spatial metaphor to enable direct manipulation of a social network.

    Nutritional risk screening is typically done in clinical settings to identify individuals at risk of malnourishment. This article presents the first population-level assessment of nutritional risk based on a large national sample representative of Canadian householders aged 65 or older. Data from the 2008/2009 Canadian Community Health Survey-Healthy Aging were used to estimate the prevalence of nutritional risk by selected characteristics. Factors associated with nutritional risk were examined with restricted and full logistic models. The distribution of responses on the SCREEN II-AB nutritional risk instrument is reported. Based on the results of the 2008/2009 survey, 34% of Canadians aged 65 or older were at nutritional risk. Women were more likely than men to be at risk. Among people with depression, 62% were at nutritional risk, compared with 33% of people without depression. Level of disability, poor oral health, and medication use were associated with nutritional risk, as were living alone, low social support, infrequent social participation, and not driving on a regular basis. Lower income and education were also associated with nutritional risk. Nutritional risk is common among seniors living in private households in Canada. The characteristics of people most likely to be at nutritional risk provide evidence for targeted screening and assessment.

  2. Federally sponsored multidisciplinary research centers: Learning, evaluation, and vicious circles.

    Youtie, Jan; Corley, Elizabeth A

    2011-02-01

    Despite the increasing investment in multi-year federally funded science and technology centers in universities, there are few studies of how these centers engage in learning and change based on information submitted from various agents in the oversight and evaluation process. One challenge is how to manage and respond to this evaluative information, especially when it is conflicting. Although the center can learn and adapt in response to this information, it can also become subject to a vicious circle of continuous restructuring and production of documentation to address various and potentially inconsistent recommendations. In this paper we illustrate the effects of such a dynamic based on our experiences as external evaluators of the $25 million NSF-funded Learning in Informal and Formal Environments (LIFE) Center. The case study presents an analysis of annual reports and strategic planning documents along with other sources of evidence to illustrate the evolution of center organizational approaches in response to evaluations by external review panels, center evaluators, program managers, and other external stakeholders. We conclude with suggestions for how evaluators may help centers ease the cost of learning and reduce the likelihood of a vicious circle. 2010 Elsevier Ltd. All rights reserved.

  3. Development of a compact six-circle goniometer.

    1998-05-01

    A compact versatile six-axis goniometer has been built which can be used with the scattering plane vertical or horizontal for anomalous X-ray diffraction and diffraction X-ray absorption fine structure using a tunable X-ray undulator at SPring-8. The diffractometer consists of a four-circle goniometer for the standard omega, 2theta, phi and chi motions and a two-circle goniometer on the 2theta arm for mounting the detector and analyser crystal. The goniometer is controlled via Ethernet, and standard data-acquisition software with a graphical user interface has been developed. A closed-cycle helium cryostat is mounted on the omega axis for temperature-dependent experiments from 330 K to 14 K. Preliminary experiments on a Bi(2)Sr(2)CaCu(2)O(8) single crystal demonstrate the performance. Superstructure peaks due to the one-dimensional spatial modulations in the b axis were recorded as a function of temperature above 20 K using an image plate.

  4. Increasingly branched rolling circle amplification for the cancer gene detection.

    2016-12-15

    An increasingly branched rolling circle amplification (IB-RCA) which contains a padlock probe (PP) and a structurally tailored molecular beacon (MB) was innovatively developed for highly sensitive detection of cancer gene, Kras gene codon 12. In this system, the PP can be circularized after hybridization with the precisely-matched target DNA, while the stem of MB can be also opened by target DNA, resulting in hybridization with the circularized PP to generate a long tandem single-stranded DNA (ssDNA) product. Since the MB is also designed to hybridize with ssDNA product, the newly-opened MBs are able to trigger the next RCA reactions, therapy producing branched rolling circle amplification (RCA) products and in turn leading to the increasingly branched RCA (IB-RCA). This alternately and continuously operates hybridization-based MB opening and opened MBs-triggered RCA. As a result, a great number of MBs are opened that is associated with a dramatically amplified fluorescent signal, enabling to quantify target DNA down to 100 fM. This sensing method demonstrates a new concept of IB-RCA amplification even in a simple way to efficiently transduce the fluorescence signal, accomplishing the highly sensitive and selective detection of cancer gene.

    Mutations in Kras gene may be used as a diagnostic marker and a target for treatment of the broad spectrum of human cancers. In this study, we developed a new class of amplification assay, double-hairpin molecular beacon (DHMB)-based cascade rolling circle amplification (RCA), for ultrasensitive and selective detection of Kras gene in a homogenous solution. Specifically, target DNA can hybridize with DHMB and activate cyclical target strand-displacement polymerization (CTDP) and nicking-mediated strand-displacement polymerization (NMDP). The resulting nicked/displaced fragments substantially outnumber target DNA and cause the cascade rolling circle amplification (C-RCA) and nicked fragment-induced strand-displacement polymerization (NFDP). Even if four amplification processes are designed, only DHMB, padlock probe and polymerization primer are involved. Under optimized conditions, this screening system exhibits a linear range of 5 orders of magnitude (from 100fM to 20nM), and the detection limit is down to 16fM. Moreover, the developed biosensing system offers a high assay specificity for perfectly matched target DNA, and the measured data from practical samples demonstrated the potential application in the cancer diagnoses. As a proof-of-concept genetic assay, the novel signaling strategy, as well as desirable analytical capability, would significantly benefit the development of versatile amplification gene profiling platforms, revealing great promise in biological studies and medical diagnostics.

We choose as a model the one-parameter family of two-colour rotations S{sub {epsilon}}(x)=S{sub (2{tau},{tau},{epsilon})}(x), where {tau}=(1+{radical}5 )/2 is the golden ratio, which have rotation rank d=2.

An exact formula is obtained for the function {nu}({epsilon}) of frequency distribution of points of the orbits under the action of S{sub {epsilon}}.

    2017-12-01

    Full Text Available We examine the conditions under which a signed graph contains an edge or a vertex that is contained in a unique negative circle or a unique positive circle. For an edge in a unique signed circle, the positive and negative case require the same structure on the underlying graph, but the requirements on the signature are different. We characterize the structure of the underlying graph necessary to support such an edge in terms of bridges of a circle. We then use the results from the edge version of the problem to help solve the vertex version.

    2012-01-01

    Full Text Available Dental materials are specific materials that were developed as a general materials for specific aplication in oral environment. To determinate the functional properties of this materials, we are obligated to use nonstandard approach and specific methods. In this study, two methodologies of material testing-artificial agging and quantification of visual informations for life circle assessment of hydroxyapatite (Hap based materials, were used. Hap was chemically synthetized which produced the material with high purity and crystallinity. Artificially produced Hap is used in stomatology for repair of bone tissue, as a filling for periodontal defects, and as a preservative augmentation for alveolar ridges. In the mean time those materials are used for definitive root canal obturation in endodontic therapy procedure as an apical plug or as complete filling material. This research was focused on the analysis of the bonding properties of the Hap based materials to the root canal walls. The methodology of artificial agging was used together with the quantification of visual informations in purpose to quantify the Hap bonding properties and bonding quality. Experiments were done in-vitro, with the artificia saliva as the agressive agent. The experimental tooths were analyzed by the high resolution optical microscope for the morphological characterisation of the bonding layer. The model for the bond life circle assessment was developed. Hap based materials proved that has favorable properties for the dental use. The presented results proved that the combination of two methodologies (artificial agging and quantification of visual informations could be used as the tool for analyzing the material-dentine interaction.

  14. Adhesion Circle: A New Approach To Better Characterize Directional Gecko-Inspired Dry Adhesives.

    Wang, Yue; Lehmann, Samuel; Shao, Jinyou; Sameoto, Dan

    2017-01-25

    The number of different designs of directional gecko-inspired adhesives has proliferated over the past 15 years, but some basic characterization tools are still nonstandardized, which can make direct comparisons of different adhesives in the literature difficult. By far the most common type of test for directional adhesives, the load-drag-pull (LDP) test is useful but can miss substantial information on the exact behavior of gecko-inspired adhesives in a variety of loading conditions. Other test techniques, including angled approaches and pull-offs, have been employed by a few groups but they are not as widely adopted; peel tests can be employed but require a larger amount of adhesive material to use in the test, which is not always practical given some current manufacturing constraints. Very few tests have looked at the effect of off-main axis loads on the performance of directional adhesives, however, and this quality of performance may be very important in applications where direct control over displacements or angle of pull-off in pitch and yaw of the peeling interface may not be practical or possible. To address this overlooked area of characterization, we introduce a new test concept for anisotropic adhesives, the adhesion circle, and also compare how the radial normal adhesion performance is altered depending on whether the pull-off comes after a displacement drag or when pulled at a constant angle from vertical after a preload. Testing directional adhesive designs made with different geometries shows that unexpected behaviors at pull-off angles not in the direction of the strong-weak axis can sometimes be seen. The complete adhesion circle tests should help better design directional adhesives for scaled up performance, and can be completed with relatively simple hardware that is typically used in most current directional adhesive tests.

  16. A new enzymatic route for production of long 5'-phosphorylated oligonucleotides using suicide cassettes and rolling circle DNA synthesis

    Directory of Open Access Journals (Sweden)

    Stougaard Magnus

    2007-08-01

    Full Text Available Abstract Background The quality of chemically synthesized oligonucleotides falls with the length of the oligonucleotide, not least due to depurinations and premature termination during production. This limits the use of long oligonucleotides in assays where long high-quality oligonucleotides are needed (e.g. padlock probes. Another problem with chemically synthesized oligonucleotides is that secondary structures contained within an oligonucleotide reduce the efficiency of HPLC and/or PAGE purification. Additionally, ligation of chemically synthesized oligonucleotides is less efficient than the ligation of enzymatically produced DNA molecules. Results Chemically synthesized oligonucleotides with hairpin structures were acquired from our standard supplier. The stem of the hairpin contained recognition sequences for the Nt. Alw I nicking enzyme and the Mly I restriction enzyme. These double stranded regions were positioned in a way to allow self-templated circularization of the oligonucleotide. Following ligation, tandem repeats of the complementary sequence of the circular oligonucleotide could be produced through rolling circle DNA synthesis. By running successive rounds of ligation, rolling circle DNA synthesis, and nicking, the original oligonucleotide could be amplified as either the (+-strand or the (--strand. Alternatively, the hairpin structure could be removed by cleavage with the Mly I restriction enzyme, thereby releasing the oligonucleotide sequence contained within the hairpin structure from the hairpin. Conclusion We present here a method for the enzymatic production through DNA amplification of oligonucleotides with freely designable 5'-ends and 3'-ends, using hairpin-containing self-templating oligonucleotides. The hairpin comprises recognition sequences for a nicking enzyme and a restriction enzyme. The oligonucleotides are amplified by successive rounds of ligation, rolling circle DNA synthesis and nicking. Furthermore, the

    This paper shows a technique based on CHT (Circle Hough Transform) to achieve the optical Braille recognition (OBR). Unlike other papers developed around the same topic, this one is made by using Hough Transform to process the recognition and transcription of Braille cells, proving CHT to be an appropriate technique to go over different non-systematics factors who can affect the process, as the paper type where the text to traduce is placed, some lightning factors, input image resolution and some flaws derived from the capture process, which is realized using a scanner. Tests are performed with a local database using text generated by visual nondisabled people and some transcripts by sightless people; all of this with the support of National Institute for Blind People (INCI for their Spanish acronym) placed in Colombia.

    Students from an urban middle school participated in a Science Book Club for one semester using the literature circles format. These students voluntarily attended twice weekly lunch meetings, reading books that followed their Grade 7 science classes. Groups of three to six participants read the same text, each performing rotating jobs to improve group discussions during meetings. When a group completed a book, participants created a presentation to share what they learned with the other groups in the club and the researcher/teacher. This research measured gains in science content knowledge and language arts skills focusing on reading comprehension, and literary response and analysis. Gains were measured using pre-existing district benchmarks. An ANCOVA showed that while no gains were found in science content knowledge, there were gains in language arts in the areas of reading comprehension and literary response and analysis.

    Full Text Available The aim of this study is to explore the particular examples of literature circles which were seen as wisdom centre and were influential in 18th century Ottoman social and cultural life. This study foc uses on the literature circles in the capital of Ottomans and examines their roles in the transmission of cultural heritage. Mahfil, which means the meeting place, became the centre of literature activities which are performed in a particular place. This li terature circles gained the status of being a prestigious literature and art centre which witnessed the creation of significant works in 18th. They functioned as a transmitter of culture in terms of the works studied and role model literary figures. Patron age tradition promoted the progress of literary activities in the circles. With regard to their significant contribution to the Ottoman culture and civilization, literature circles emerged at the patronage of Sultan III. Ahmed, Sultan III. Selim, Sadrazam Nevşehirli Damad İbrahim Paşa, Sadrazam Koca Râgıb Paşa, Hoca Neş’et Efendi, Şeyh Gâlib, Hoca Süleyman Vahyî. Therefore, it is essential to study these circles in terms of its importance as being home to important literary figures with a sophisticated sen se of art.

    Full Text Available Background & Objectives: The Circle of Willis represents the important anastomotic cerebral vessels at the base of the brain. Variation in the Circle of Willis is common. A complete or normal Circle of Willis varies widely in the literature. As no prior data on the variations of Circle of Willis is available on Nepalese population, this study was undertaken in patients undergoing CT Angiography.Materials & Methods: During the period July 2016 till Dec 2016, 65 patients who were referred for brain CT Angiography (Toshiba Aquilion Prime 160 slice Multi Detector CT scanner from medicine, neurology and neuro-surgery were included in the study. CT scans were taken from the base of skull to the vertex. In addition to the axial source data, post-processed multiplanar reformatted (MPR, maximum-intensity projection (MIP, and 3D volume-rendering (VR images were evaluated. Results: Of the 65 patients who underwent CT Angiography a normal or complete Circle of Willis was seen in only 35.4 % (23 patients. The most common variant of the Circle of Willis was a hypoplastic Pcom seen in 26.2 % (17 patients. This was followed by fetal origin of PCA seen in 13.8 % (9 patients. An absent Pcom and hypoplastic / absent Acom was in 12.3 % each (8 patients each. Conclusion: Variation in the Circle of Willis is common. Variations in the posterior portion of the Circle of Willis are more common than the anterior portion.

    2017-05-01

    To describe our experience with the circle nephrostomy tube (NT) (Cook Medical), a drainage system uniquely designed for use after multiple-access percutaneous nephrolithotomy (PNL). A retrospective review of 1317 consecutive patients undergoing 1599 PNLs at IU Health Methodist Hospital was performed. All multiple access cases utilizing circle NTs were reviewed and analyzed. The method of insertion of circle NT was demonstrated. A total of 1843 accesses were obtained in 1599 renal units (RUs): 380 upper pole, 129 interpolar, and 1334 lower pole. Multiple accesses in this series were required in 282 RUs (17.6%). Following multiple-access PNL, circle NTs, Cope loop, and reentry Malecot NTs were inserted in 91 RUs (32.3%), 208 RUs (73.8%), and 31 RUs (11%), respectively. None of the patients who had circle NT experienced clogging, dislodgement, or obstruction of the tube. The cost of circle, Cope loop, and Malecot NTs are 121.73 USD, 95.20 USD, and 81 USD, respectively. Circle NTs are easy to insert, secure, cost-effective compared with inserting two NTs. Circle NTs provide excellent drainage and facilitate secondary procedures. Copyright © 2017 Elsevier Inc. All rights reserved.

    Koreň, Milan; Mokroš, Martin; Bucha, Tomáš

    2017-12-01

    This study compares the accuracies of diameter at breast height (DBH) estimations by three initial (minimum bounding box, centroid, and maximum distance) and two refining (Monte Carlo and optimal circle) circle-fitting methods The circle-fitting algorithms were evaluated in multi-scan mode and a simulated single-scan mode on 157 European beech trees (Fagus sylvatica L.). DBH measured by a calliper was used as reference data. Most of the studied circle-fitting algorithms significantly underestimated the mean DBH in both scanning modes. Only the Monte Carlo method in the single-scan mode significantly overestimated the mean DBH. The centroid method proved to be the least suitable and showed significantly different results from the other circle-fitting methods in both scanning modes. In multi-scan mode, the accuracy of the minimum bounding box method was not significantly different from the accuracies of the refining methods The accuracy of the maximum distance method was significantly different from the accuracies of the refining methods in both scanning modes. The accuracy of the Monte Carlo method was significantly different from the accuracy of the optimal circle method in only single-scan mode. The optimal circle method proved to be the most accurate circle-fitting method for DBH estimation from point clouds in both scanning modes.

  2. Circle communication: an old form of communication useful for 21st century leadership.

    Science.gov (United States)

    Michaels, Cathleen L

    2002-01-01

    Circle communication is a form of group exchange that builds a network of relationships, a sense of community. Through practices of active listening, intentional speaking, and conscious self-monitoring, circle communication emphasizes individual contribution while building consensus to fulfill the purpose of the group. In this regard, circle communication supports a shared leadership in which all individual and unique perspectives are engaged to create the common ground for action. Circle communication emerges from a shared humanity, which can balance the "division of labor" and people only being known by their specific organizational roles. Both are needed to sustain an organization. By nurturing the human side, regardless of role and function, circle communication intersects with diversity or the uniqueness of each individual, storytelling, coaching, guiding, and mentoring, as well as discovering and responding to conflict.

  4. Vision-based technique for circle detection and measurement using lookup table and bitwise center accumulator.

    Science.gov (United States)

    Yu, Hancheng; Wang, Tuo

    2017-03-01

    In this paper, we proposed a fast algorithm for circle detection and measurement, which uses a lookup table and bitwise center accumulator (LUT-BCA). The LUT-BCA is a two-stage procedure. The first stage determines the candidate circle centers with normal lines produced by the lookup table and recorded by the bitwise center accumulator. The second stage computes the radius of each candidate circle center and validates these centers, which eliminates the false detections. The proposed LUT-BCA can also be easily implemented on massively parallel high-performance graphics hardware using the compute unified device architecture. Experimental results indicate that the LUT-BCA can locate circle centers and measure their radii accurately and is very suitable for real-time circle detection and measurement.

  5. A new method for fast circle detection in a complex background image

    Wu, Meijun; Yang, Jie; Sun, Yadong

    2011-11-01

    A new method for circle detection, Hough gradient clustering method, has been developed in this paper. By using gradient direction angle to find the diameter of a circle, the new method can rapidly detect the circle in a complex background. The crucial steps in this method are the feature extraction and the clustering of the points which have the same gray direction angle and are collinear along the gradient direction. The application of the two-to-one space mapping and 1-2Hough transform can further reduce the useless calculation in the process of circle detection. Comparing with the Hough gradient method in OpenCV, the newly developed method shows a higher efficiency of circle detection in a complex background image as well as a great improvement in the anti-noise ability.

    2017-08-01

    We conducted a systematic review of studies reporting on the effectiveness of Circles of Support and Accountability (Circles). Circles use volunteers to provide support for sex offenders living in the community. We searched 10 databases up to the end of 2013 and identified 3 relevant outcome studies. An additional 12 papers or reports were identified by searching reference lists, Google, and contacting key authors and Circles providers to obtain unpublished data. These 15 studies comprised one randomized controlled trial, three retrospective cohorts with matched controls, and 11 case series. The majority reported measures of recidivism, particularly reconviction. The 4 studies with controls generally reported that participation in Circles was associated with lower recidivism although there were few statistically significant differences. Few studies examined changes in risk or psychosocial outcomes. A number of methodological issues are discussed. Longer term, prospective follow-up studies with control groups are required to address these issues.

    2017-03-01

    The proposed implementation of work hour restrictions has presented a significant challenge of maintaining the quality of resident education and ensuring adequate hands-on experience that is essential for novice surgeons. To maintain the level of resident surgical competency, revision of the apprentice model of surgical education to include supplementary educational methods, such as laboratory and virtual reality (VR) simulations, have become frequent topics of discussion. We aimed to better understand the role of supplementary educational methods in Canadian neurosurgery residency training. An online survey was sent to program directors of all 14 Canadian neurosurgical residency programs and active resident members of the Canadian Neurosurgical Society (N=85). We asked 16 questions focusing on topics of surgeon perception, current implementation and barriers to supplementary educational models. Of the 99 surveys sent, 8 out of 14 (57%) program directors and 37 out of 85 (44%) residents completed the survey. Of the 14 neurosurgery residency programs across Canada, 7 reported utilizing laboratory-based teaching within their educational plan, while only 3 programs reported using VR simulation as a supplementary teaching method. The biggest barriers to implementing supplementary educational methods were resident availability, lack of resources, and cost. Work-hour restrictions threaten to compromise the traditional apprentice model of surgical training. The potential value of supplementary educational methods for surgical education is evident, as reported by both program directors and residents across Canada. However, availability and utilization of laboratory and VR simulations are limited by numerous factors such as time constrains and lack of resources.

    Various hydroelectric power projects in southern African countries that have benefited from Canadian expertise and assistance under the Southern African Development Community (SADC) AAA.3.4 Hydroelectric Hydrological Assistance Project, were described. The project aims to upgrade the operational hydrology units of the SADC hydroelectric utilities in the Zambezi River Basin, focusing particularly on improving the quality, availability, accessibility and utility of the hydrometric data used for inflow forecasting and inventory purposes. The data is also used for planning and operations. A current usage is to assess the sustainability of the systems implemented under the program. BC Hydro, and the Water Survey of Canada are the principal Canadian agencies involved in providing the technical expertise. Increased confidence in inflow forecasts, increased energy production, reduced loss of water due to unnecessary spilling, improved ability to safely route floods, and to cope with droughts, and improved data for design and dam safety studies are just some of the benefits derived from this example of Canadian technical assistance in the developing countries. 12 refs., 6 tabs., 4 figs.

    Kuchinka, Jacek

    2017-08-01

    Arterial circles of brains from 70 adult chinchillas were filled with synthetic latex. The arterial circle of the brain is formed as the result of vertebral arteries being merged into the basilar artery. Caudally, both vertebral arteries gave rise to the ventral spinal artery. The ventral spinal artery splits into tiny cerebellar vessels, the pontine and cochlear branches. Distally, the basilar artery ramified into two terminal branches that formed the arterial circle of brain, rostrally open in most cases (75%). The observed variability of the arterial circle of brain of chinchillas pertained to all elements of that circle. The greatest variability within the vessels of the circle of Willis in chinchillas was observed in 22 cases (31.4%) of internal ophthalmic arteries. In chinchillas, a trend toward slight variability within the arteries comprising the arterial circle of the brain was observed in 44 animals. This accounted for 62.8% of all cases. Only in three cases was the arterial circle of brain clearly symmetrical. At the same time, 23 animals (32.8%) revealed features of significant vascular variability within the brain base region. These consisted of disturbed geometry of the entire arterial circle, different levels of ramifications into individual arteries, as well as the number and diameter of arteries. No internal carotid arteries were observed in chinchillas apart from one atypical case in which the carotid artery extended unilaterally into the basilar artery. These investigations indicate on the significant variability of arterial circle in rodents. Anat Rec, 300:1472-1480, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  10. Canadian health system. Rationing, social policy and hysteria.

    Science.gov (United States)

    Tepperman, B S

    1991-04-01

    The Canadian health care system is a recipe for lowest common denominator medical care. It imposes many of the same restrictions experienced in the United States in the gatekeeper HMO model. Centralized government control allows a more thorough ratcheting down of costs and growth limitation by bureaucracy at all levels responding to political expediency without needing to address actual medical need. Yes, in theory Canadians enjoy the full range of therapies and services available in any medical market in the United States and, yes, undoubtedly it is cheaper. Access in theory to first-dollar coverage for services does not translate well to practice if patients do not survive long enough to keep their appointment for that therapy or service. Clearly, the advocates of an American adaptation of the Canadian health care system are serious and should not be treated lightly. They understand dollars but not patients and their needs. They measure quality and efficiency of care in terms of hospital bed utilization and generic screens, not in terms of being able to deliver the best achievable appropriate care to the greatest number of eligible patients. The multiple levels of government control and the absence of effective competition in the Canadian model allow significant cost reductions in health care, but at the expense of the available range of treatment options and access to treatment. Imposition of this model in the United States would require closure of some existing facilities and reduced access to those remaining, leading inevitably to a substantial reduction of the standard of medical care practically achievable by each of us for our patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Clinical research bridges patients’ unmet medical need with innovative medicines, increases knowledge acquisition by clinicians, and creates solutions to improve the sustainability and quality of the Canadian health care system and economy. The Canadian Institutes of Health Research and the Canadian Lung Association have recently raised concerns over declining research activities within the Canadian respiratory community. While there are currently >3000 ongoing clinical trials in Canada, the number of trials investigating common respiratory diseases is unknown. The objective of the present study was to monitor the trends in industry- and non-industry-sponsored respiratory clinical trials in Canada from 2001 to 2011. Trialtrove 2012 (Citeline, an Informa UK business, a database containing summarized clinical trial information regarding pharmaceutical products, was searched using common chronic respiratory disease terms: “allergic rhinitis”, “asthma”, “chronic obstructive pulmonary disease (COPD”, “cystic fibrosis”, “respiratory infections”, “pulmonary fibrosis” and “smoking cessation”. Over the past 10 years, the number of respiratory clinical trials conducted in Canada has increased (4.49 per year; P=0.004. From 2001 to 2011, the majority of trials were performed in asthma, followed closely by respiratory infections and COPD. Over the past decade, the number of trials investigating COPD and respiratory infections increased (P<0.05, while asthma trials showed a declining trend since 2007. Of the clinical trials performed during this 10-year period, the majority were in phase III, with a significant increase in the number of phase II trials (2.49 per year; P=0.008. However, certain trends observed are concerning and warrant further monitoring in the coming years.

    Full Text Available The article looks at the role Circle of Concerned African Women Theologians (the Circle have played in the struggle to end or reduce the rate at which violence against women and girls occurs in West Africa by highlighting the contributions of older Circle women, especially the initiator of the Circle, Mercy Amba Oduyoye. The initiator of the Circle and other older Circle women have left a remarkable legacy that needs to continue by the current and future generations of the Circle. The background information examines the leadership and mentorship of Mercy Amba Oduyoye and the impact she has made in the lives of African women. The essay then looks at the types of violence that women face in West Africa with the specific contributions of Circle women in the struggle to end violence against women and girls. It then argues that Circle women have played very significant roles both in setting the pace and giving the platform for women activities to minimise gender-based violence against women and girls. Circle women have written and presented papers that have addressed many challenges including HIV and/or AIDS, Girl Child trafficking, Marriage of Minors, and almost all kinds of violence against women and girls. Currently, religious violence threatens the fabric of African nations causing insecurity and panic, women and girls being the most vulnerable. The challenge to the present and future Circle members is to contribute in significant ways towards religious harmony in Africa and beyond. The Circle acknowledges the leadership role of women and encourages them to spearhead the liberation of women as well as empower them to be able to aspire to get to the top or become independent. No one understands what someone else feels better than the person experiencing the ordeal. Women can better understand what they go through and also have the passion to strive towards liberation.Intradisciplinary and/or interdisciplinary implications: In this article, the

  13. A comprehensive study of the anatomical variations of the circle of willis in adult human brains.

    Cerebrovascular diseases such as stroke, aneurysms and arterio-venous malformations are very much prevalent in our country. Circle of Willis, as an anastomotic polygon at the base of the brain forms an important collateral network to maintain adequate cerebral perfusion. Changes in the normal morphology of the circle may condition the appearance and severity of symptoms of cerebrovascular disorders, such as aneurysms, infarctions and other vascular anomalies. A possible link between abnormalities of the circle of Willis and the mentally ill patients has been observed. The aim of the present study is to have an intimate knowledge of the variations in the cerebral arterial circle and to clarify the clinical importance of these variations in certain forms of cerebrovascular diseases. So an attempt was made to analyse the anatomical variations of the circle in a random population. The work was based on fifty adult brains from persons died of diverse causes. The materials were obtained during routine autopsy studies. The base of the brain including the brain stem with intact arterial circle was preserved in 10% formalin for 10 days. The circle of Willis and its major branches were carefully dissected under water using a magnifying lens. The variations were recorded and photographed. Majority of the circles (52%) showed anomalies. Hypoplasia was the most frequent anomaly and was found in 24% of the brains. Accessory vessels in the form of duplications/triplications of anterior communicating artery were seen in 12% of the circles. The embryonic origin of the posterior cerebral artery from the internal carotid persisted in 10% of the circles. An incomplete circle due to the absence of one or other posterior communicating artery was found in 6% of the specimens.Variations are more frequent in posterior half of the circle. The anatomical variations of the circle of Willis were probably genetically determined, develop in early embryonic stage and persist in post natal life

  14. Medical cannabis – the Canadian perspective

    Ko, Gordon D; Bober, Sara L; Mindra, Sean; Moreau, Jason M

    2016-01-01

    Cannabis has been widely used as a medicinal agent in Eastern medicine with earliest evidence in ancient Chinese practice dating back to 2700 BC. Over time, the use of medical cannabis has been increasingly adopted by Western medicine and is thus a rapidly emerging field that all pain physicians need to be aware of. Several randomized controlled trials have shown a significant and dose-dependent relationship between neuropathic pain relief and tetrahydrocannabinol – the principal psychoactive component of cannabis. Despite this, barriers exist to use from both the patient perspective (cost, addiction, social stigma, lack of understanding regarding safe administration) and the physician perspective (credibility, criminality, clinical evidence, patient addiction, and policy from the governing medical colleges). This review addresses these barriers and draws attention to key concerns in the Canadian medical system, providing updated treatment approaches to help clinicians work with their patients in achieving adequate pain control, reduced narcotic medication use, and enhanced quality of life. This review also includes case studies demonstrating the use of medical marijuana by patients with neuropathic low-back pain, neuropathic pain in fibromyalgia, and neuropathic pain in multiple sclerosis. While significant preclinical data have demonstrated the potential therapeutic benefits of cannabis for treating pain in osteoarthritis, rheumatoid arthritis, fibromyalgia, and cancer, further studies are needed with randomized controlled trials and larger study populations to identify the specific strains and concentrations that will work best with selected cohorts.

    To establish health-related reasons behind Canadian food choices, and how variables such as education, income, gender, ethnicity and age may affect food selection. Approximately 98 733 Canadians responded to the 12 questions regarding food choices in the Canadian Community Health Survey (CCHS) cycle 2.1, conducted by the Canadian Government in 2003. These included 13 727 adolescents (12-19 years), 19 089 young adults (20-34 years), 31 039 middle-aged adults (35-54 years), 25 338 older adults (55-74 years) and 9580 elderly (75+ years). Approximately 70% of Canadian adolescents in the sample indicated that their food choices were independent of health concerns. Body weight management was a major concern for food selection by adolescents and adults, while the elderly stated heart disease as their main concern. Among all participants, females, and individuals with high levels of education and income reported the highest response to choosing or avoiding foods due to health concerns and food content. Our data indicate that several factors significantly affect food choices for health-related reasons in the Canadian population. Among them, age- and gender-related gaps, particularly between adolescents and adults, are profound. This observation may urge authorities to implement effective strategies to educate Canadians, especially adolescents, that selection of appropriate foods may prevent chronic diseases.

    Spirometry plays a major role in the diagnosis and assessment of severity of lung disease. Determining which lung function values are normal and which are below the lower limit of normal depends on reference equations derived from an appropriate population. The purpose of this study was to derive spirometric reference equations for the Canadian population. The Canadian Health Measures Survey consisted of a respiratory questionnaire, urinary cotinine measurements, and spirometry performed in the sitting position with rigorous quality control standards. Of the 16,606 respondents between 6 and 79 years of age, 11,145 were eliminated for positive responses to the respiratory questionnaire, tobacco exposure, or inability to provide high-quality spirograms. Of the remaining 5,461, roughly half were less than 18 years of age. Quantile regression was used to derive predictive (median) and lower limit of normal equations for males and females for FEV1, FVC, and FEV1/FVC ratio for those with ages greater and less than 18 years. The resulting equations were compared with those from the Global Lung Initiative (GLI) and National Health and Nutrition Examination Survey (NHANES) III by using an ideal subject on the 50th percentile for height and between the ages of 6 and 79 years; the comparison showed minor and inconsistent discrepancies among the predictive equations. A plot of residuals (predicted minus measured value for each subject) suggested a marginally better fit compared with the GLI and NHANES III equations, although differences among the equations were small and unlikely to have any clinical significance. This study provides spirometric reference equations for the Canadian population that were measured under the recommended clinical conditions and with rigorous quality control.

    An overview of the various tritium research and operational activities in Canada is presented. These activities encompass tritium processing and recovery, tritium interactions with materials, and tritium health and safety. Many of these on-going activities form a sound basis for the tritium use and handling aspects of the ITER project. Tritium management within the CANDU heavy water reactor, associated detritiation facilities, research and development facilities, and commercial industry and improving the understanding of tritium behaviour in humans and the environment remain the focus of a long-standing Canadian interest in tritium. While there have been changes in the application of this knowledge and experience over time, the operating experience and the supporting research and development continue to provide for improved plant and facility operations, an improved understanding of tritium safety issues, and improved products and tools that facilitate tritium management.

    An anonymous, self-administered, mail-out survey of Canadian Orthodontists was conducted to evaluate the characteristics of orthodontic Internet use. The response rate was 45.6% (304 of 667). A total of 76.6% of orthodontists reported having Internet access at work, and an additional 12.4% reported having Internet access from a different location. Statistically significant associations between Internet usage and office staff size (P < .001) and years of practice (P = .046) were observed. Offices with larger staffs had greater Internet access. Number of staffs and number of case starts were positively correlated (P < .001, r = 0.498). The odds ratio for having Internet access on the basis of increased case starts from the less than 100 to 300-399 categories was 5.67. Although not statistically significant, there was a trend for greater Internet access by younger practitioners.
