    2015-01-01

    The aim of this study was to examine whether changes over time in reported area crime and perceived area safety were related to self-rated general health and physical activity (PA), in order to provide support for a causal relationship between social safety and health. Additionally, we investigated whether social cohesion protects the residents against the negative impact of unsafe areas on health and PA. Multilevel logistic regression analyses were performed on Dutch survey data, including 47,926 respondents living in 2974 areas. An increase in area level unsafety feelings between 2009 and 2011 was associated with more people reporting poor general health in 2012 in that area, but was not related to PA. Changes in reported area crime were not related to either poor general health or PA. The social cohesion in the area did not modify the effect of changes in social safety on health and PA. The results suggest that tackling feelings of unsafety in an area might contribute to the better general health of the residents. Because changes in area social safety were not associated with PA, we found no leads that such health benefits were achieved through an increase in physical activity.

    2016-01-01

    We investigate the dynamics and interplay between human communication, movement, and social proximity by analyzing data collected from smartphones distributed among 638 individuals. The main question we consider is: to what extent do individuals act according to patterns shared across an entire population? Based on statistics of the entire population, we successfully predict 71\\% of the activity and 85\\% of the inactivity involved in communication, movement, and social proximity. We find that individual level statistics only result in marginally better predictions, indicating a high degree of shared activity patterns across the population. Finally, we predict short-term activity patterns using a generalized linear model, which suggests that a simple linear description might be sufficient to explain a wide range of actions, whether they be of social or of physical character.

    2003-01-01

    General practice computer systems already have a number of important safety features. However, there are problems in that general practitioners (GPs) have come to rely on hazard alerts when they are not foolproof. Furthermore, GPs do not know how to make best use of safety features on their systems. There are a number of solutions that could help to improve the safety features of general practice computer systems and also help to improve the abilities of healthcare professionals to use these ...

    A concept is described for evaluating the general aviation mid-air collision hazard in uncontrolled terminal airspace. Three-dimensional traffic pattern measurements were conducted at uncontrolled and controlled airports. Computer programs for data reduction, storage retrieval and statistical analysis have been developed. Initial general aviation air traffic pattern characteristics are presented. These preliminary results indicate that patterns are highly divergent from the expected standard pattern, and that pattern procedures observed can affect the ability of pilots to see and avoid each other.

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

    General aviation includes all civilian aviation apart from operations involving paid passenger transport. Unfortunately, this category of aviation holds a lackluster safety record, accounting for 94% of civil aviation fatalities. In 2014, of 1143 general aviation accidents, 20% were fatal compared with 0 of 29 airline mishaps in the United States. Herein, research findings over the past 30 yr will be reviewed. Accident risk factors (e.g., adverse weather, geographical region, post-impact fire, gender differences) will be discussed. The review will also summarize the development and implementation of stringent crashworthiness designs with multi-axis dynamic testing and head-injury protection and its impact on mitigating occupant injury severity. The benefits and drawbacks of new technology and human factor considerations associated with increased general aviation automation will be debated. Data on the safety of the aging general aviation population and increased drug usage will also be described. Finally, areas in which general aviation occupant survival could be improved and injury severity mitigated will be discussed with the view of equipping aircraft with 1) crash-resistant fuel tanks to reduce post-impact conflagration; 2) after-market ballistic parachutes for older aircraft; and 3) current generation electronic locator beacons to hasten site access by first responders.Boyd DD.

    2015-12-01

    Full Text Available In recent years, a new class of compact vehicles has been emerging and wide-spreading all around Europe: the quadricycle. These four-wheeled motor vehicles, originally derived from motorcycles, are a small and fuel-efficient mean of transportation used in rural or urban areas as an alternative to motorbikes or city cars. In some countries, they are also endorsed by local authorities and institutions which support small and environmentally-friendly vehicles. In this paper, several general considerations on quadricycles will be provided including the vehicle classification, evolution of regulations (as homologation, driver licence, emissions, etc, technical characteristics, safety requirements, most relevant investigations, and other additional useful information (e.g. references, links. It represents an important and actual topic of investigation for designers and manufacturers considering that the new EU regulation on the approval and market surveillance of quadricycles will soon enter in force providing conclusive requirements for functional safety environmental protection of these promising vehicles.

    Full Text Available The purpose of this study was to describe the presence and quality of active transportation safety features in Canadian school environments that relate to pedestrian and bicycle safety. Variations in these features and associated traffic concerns as perceived by school administrators were examined by geographic status and school type. The study was based on schools that participated in 2009/2010 Health Behaviour in School-aged Children (HBSC survey. ArcGIS software version 10 and Google Earth were used to assess the presence and quality of ten different active transportation safety features. Findings suggest that there are crosswalks and good sidewalk coverage in the environments surrounding most Canadian schools, but a dearth of bicycle lanes and other traffic calming measures (e.g., speed bumps, traffic chokers. Significant urban/rural inequities exist with a greater prevalence of sidewalk coverage, crosswalks, traffic medians, and speed bumps in urban areas. With the exception of bicycle lanes, the active transportation safety features that were present were generally rated as high quality. Traffic was more of a concern to administrators in urban areas. This study provides novel information about active transportation safety features in Canadian school environments. This information could help guide public health efforts aimed at increasing active transportation levels while simultaneously decreasing active transportation injuries.

    1989-11-08

    An open, noncomparative study was undertaken to examine the safety of tenoxicam, a new nonsteroidal antiinflammatory drug (NSAID) in general practice. One thousand two hundred and sixty-seven patients with rheumatic conditions were recruited by 392 general practitioners throughout New Zealand. Forty-three point six percent of patients recruited were over 65 years of age, 62.5% had some form of concomitant disease and 76.3% of patients were already receiving NSAIDs. Three hundred and four (23.9%) patients experienced adverse drug reactions, the commonest being gastrointestinal (11.4%), central and peripheral nervous system disorders (2.8%) and skin reactions (2.5%). The profile of adverse drug reactions in those more than 65 was similar to those in patients under 65 years. Of the reactions reported, 14.7% were considered severe. Three peptic ulcers were reported. There were no unexpected adverse drug reactions. Eight hundred and forty-nine patients completed 6 months treatment. Subjective assessments of overall efficacy, pain at night, pain on movement and stiffness made before treatment and at 1, 3 and 6 months posttreatment showed that tenoxicam significantly improved all parameters. The clinical response was maintained throughout the 6 month study period and was not different in patients less than or greater than 65 years.

    As the life expectancy of people in Western countries continues to rise, so too does the number of elderly patients. In parallel, robotic surgery continues to gain increasing acceptance, allowing for more complex operations to be performed by minimally invasive approach and extending indications for surgery to this population. The aim of this study is to assess the safety of robotic general surgery in patients 70 years and older. From April 2007 to December 2009, patients 70 years and older, who underwent various robotic procedures at our institution, were stratified into three categories of surgical complexity (low, intermediate, and high). There were 73 patients, including 39 women (53.4%) and 34 men (46.6%). The median age was 75 years (range 70-88 years). There were 7, 24, and 42 patients included, respectively, in the low, intermediate, and high surgical complexity categories. Approximately 50% of patients underwent hepatic and pancreatic resections. There was no statistically significant difference between the three groups in terms of morbidity, mortality, readmission or transfusion. Mean overall operative time was 254 ± 133 min (range 15-560 min). Perioperative mortality and morbidity was 1.4% and 15.1%, respectively. Transfusion rate was 9.6%, and median length of stay was 6 days (range 0-30 days). Robotic surgery can be performed safely in the elderly population with low mortality, acceptable morbidity, and short hospital stay. Age should not be considered as a contraindication to robotic surgery even for advanced procedures.

    2016-05-01

    The United States Food and Drug Administration recently removed the requirement for a General Safety Test (GST) for biologics in the Code of Federal Regulations (21 CFR 610.11). The GST, as well as abnormal toxicity (European Pharmacopeia) and innocuity tests (World Health Organization), were designed to test for extraneous toxic contaminants on each product lot intended for human use. Tests require one-week observations for general health and weight following injection of specified volumes of product batches into guinea pigs and mice. At the volumes specified, dose-related toxicity may result when the product is pharmacologically active in rodents. With vaccines, required doses may be > 3 logs higher than intended human dose on a weight-adjusted basis and if an immune modulatory adjuvant is included, systemic immune hyperactivation may cause toxicity. Herein, using the CpG/alum adjuvant combination we evaluated the different test protocols and showed their unsuitability for this adjuvant combination.

  12. Patient safety culture measurement in general practice. Clinimetric properties of 'SCOPE'

    Directory of Open Access Journals (Sweden)

    Zwart Dorien LM

    2011-11-01

    Full Text Available Abstract Background A supportive patient safety culture is considered to be an essential condition for improving patient safety. Assessing the current safety culture in general practice may be a first step to target improvements. To that end, we studied internal consistency and construct validity of a safety culture questionnaire for general practice (SCOPE which was derived from a comparable questionnaire for hospitals (Dutch-HSOPS. Methods The survey was conducted among caregivers of Dutch general practice as part of an ongoing quality accreditation process using a 46 item questionnaire. We conducted factor analyses and studied validity by calculating correlations between the subscales and testing the hypothesis that respondents' patient safety grade of their practices correlated with their scores on the questionnaire. Results Of 72 practices 294 respondents completed the questionnaire. Eight factors were identified concerning handover and teamwork, support and fellowship, communication openness, feedback and learning from error, intention to report events, adequate procedures and staffing, overall perceptions of patient safety and expectations and actions of managers. Cronbach's alpha of the factors rated between 0.64 and 0.85. The subscales intercorrelated moderately, except for the factor about intention to report events. Respondents who graded patient safety highly scored significantly higher on the questionnaire than those who did not. Conclusions The SCOPE questionnaire seems an appropriate instrument to assess patient safety culture in general practice. The clinimetric properties of the SCOPE are promising, but future research should confirm the factor structure and construct of the SCOPE and delineate its responsiveness to changes in safety culture over time.

  13. Introducing Proper Chemical Hygiene and Safety in the General Chemistry Curriculum

    Science.gov (United States)

    Miller, Gordon J.; Heideman, Stephen A.; Greenbowe, Thomas J.

    2000-09-01

    Chemical safety is an important component of science education for everyone, not just for chemistry majors. Developing a responsible and knowledgeable attitude towards chemical safety best starts at the early stages of a student's career. In many colleges and universities, safety education in undergraduate chemistry has been relegated primarily to a few regulatory documents at the beginning of a laboratory course, or an occasional warning in the description of a specific experiment in a prelaboratory lecture. Safety issues are seldom raised in general chemistry or organic chemistry lecture-based chemistry courses. At Iowa State University we have begun to implement a program, Chemical Hygiene and Safety in the Laboratory, into the undergraduate chemistry curriculum. This program is designed to increase the awareness and knowledge of proper chemical hygiene and laboratory safety issues among all students taking general chemistry and organic chemistry courses. Laboratory protocol, use of safety equipment, familiarity with MSD sheets, basics of first aid, some specific terminology surrounding chemical hygiene, EPA and OSHA requirements, and the use of the World Wide Web to search and locate chemical safety information are topics that are applied throughout the chemistry curriculum. The novelty of this approach is to incorporate MSD sheets and safety information that can be located on the World Wide Web in a series of safety problems and assignments, all related to the chemistry experiments students are about to perform. The fundamental idea of our approach is not only to teach students what is required for appropriate safety measures, but also to involve them in the enforcement of basic prudent practices.

  14. ILO activities in the area of chemical safety.

    Science.gov (United States)

    Obadia, Isaac

    2003-08-21

    The ILO has been active in the area of safety in the use of chemicals at work since the year of its creation in 1919, including the development of international treaties and other technical instruments, the provision of technical assistance to its member States, and the development of chemical safety information systems. The two key ILO standards in this area are the Conventions on safety in the use of chemicals at work (No. 170, 1990), and the Prevention of Major Industrial Accidents (No. 174, 1993). The ILO Programme on occupational safety, health and environment (Safe Work) is currently responsible for ILO chemical safety activities. In the past two decades, most of ILO work in this area has been carried out within the context of inter-agency collaboration frameworks linking the ILO, WHO, UNEP, FAO, UNIDO, UNITAR, and the OECD, including the International Programme on Chemical Safety (IPCS), the Inter-Organisation Programme for the Sound Management of Chemicals (IOMC), and the Intergovernmental Forum on Chemical Safety (IFCS). Apart from the regular development, updating and dissemination of chemical safety information data bases such as the IPCS International Chemical Cards, the elaboration of a Globally harmonized system for the classification and labelling of Chemicals (GHS) has been the most outstanding achievement of this international collaboration on chemical safety.

    BACKGROUND AND AIMS Cancer is a common, serious disease and early diagnosis is a cornerstone in the effort to improve the outcome from cancer disease. The general practitioner (GP) plays a crucial role in achieving this goal. Little is known about GPs’ suspicion of cancer and the activities the GPs...... institute in relation to such suspicion. Knowledge is also sparse on any effects of different diagnostic activities in general practice. The overall aims of this thesis were therefore: -to describe how often Danish GPs suspected cancer or other serious diseases and how they acted on the suspicion......, and to analyse how a suspicion influenced the demand for health care services and predicted a future diagnosis of serious disease - to investigate whether variation in GPs’ diagnostic activity influences cancer patients’ prognosis in relation to prostate-specific antigen (PSA) testing and prostate cancer...

  16. The Effect of Line Maintenance Activity on Airline Safety Quality

    Science.gov (United States)

    Rhoades, Dawna L.; Reynolds, Rosemarie; Waguespack, Blaise, Jr.; Williams, Michael

    2005-01-01

    One of the arguments against deregulation of the airline industry has been the possibility that financially troubled carriers would be tempted to lower line maintenance spending, thus lowering maintenance quality and decreasing the overall safety of the carrier. Given the financial crisis triggered by the events of 9/11: it appears to be a good time to revisit this issue. This paper examines the quality of airline line maintenance activity and examines the impact of maintenance spending on maintenance quality and overall safety. Findings indicate that increased maintenance spending is associated with increased line maintenance activity and increased overall safety quality for the major U.S. carriers.

    Full Text Available Anja Schweizer1, Sylvie Dejager2, James E Foley3, Wolfgang Kothny31Novartis Pharma AG, Basel, Switzerland; 2Novartis Pharma SAS, Rueil-Malmaison, France; 3Novartis Pharmaceuticals Corporation, East Hanover, NJ, USAAim: Analyzing safety aspects of a drug from individual studies can lead to difficult-to-interpret results. The aim of this paper is therefore to assess the general safety and tolerability, including incidences of the most common adverse events (AEs, of vildagliptin based on a large pooled database of Phase II and III clinical trials.Methods: Safety data were pooled from 38 studies of ≥12 to ≥104 weeks' duration. AE profiles of vildagliptin (50 mg bid; N = 6116 were evaluated relative to a pool of comparators (placebo and active comparators; N = 6210. Absolute incidence rates were calculated for all AEs, serious AEs (SAEs, discontinuations due to AEs, and deaths.Results: Overall AEs, SAEs, discontinuations due to AEs, and deaths were all reported with a similar frequency in patients receiving vildagliptin (69.1%, 8.9%, 5.7%, and 0.4%, respectively and patients receiving comparators (69.0%, 9.0%, 6.4%, and 0.4%, respectively, whereas drug-related AEs were seen with a lower frequency in vildagliptin-treated patients (15.7% vs 21.7% with comparators. The incidences of the most commonly reported specific AEs were also similar between vildagliptin and comparators, except for increased incidences of hypoglycemia, tremor, and hyperhidrosis in the comparator group related to the use of sulfonylureas.Conclusions: The present pooled analysis shows that vildagliptin was overall well tolerated in clinical trials of up to >2 years in duration. The data further emphasize the value of a pooled analysis from a large safety database versus assessing safety and tolerability from individual studies.Keywords: type 2 diabetes, dipeptidyl peptidase-4, edema, safety, vildagliptin

  20. Patient safety in primary care: a survey of general practitioners in the Netherlands

    Directory of Open Access Journals (Sweden)

    Wensing Michel

    2010-01-01

    Full Text Available Abstract Background Primary care encompasses many different clinical domains and patient groups, which means that patient safety in primary care may be equally broad. Previous research on safety in primary care has focused on medication safety and incident reporting. In this study, the views of general practitioners (GPs on patient safety were examined. Methods A web-based survey of a sample of GPs was undertaken. The items were derived from aspects of patient safety issues identified in a prior interview study. The questionnaire used 10 clinical cases and 15 potential risk factors to explore GPs' views on patient safety. Results A total of 68 GPs responded (51.5% response rate. None of the clinical cases was uniformly judged as particularly safe or unsafe by the GPs. Cases judged to be unsafe by a majority of the GPs concerned either the maintenance of medical records or prescription and monitoring of medication. Cases which only a few GPs judged as unsafe concerned hygiene, the diagnostic process, prevention and communication. The risk factors most frequently judged to constitute a threat to patient safety were a poor doctor-patient relationship, insufficient continuing education on the part of the GP and a patient age over 75 years. Language barriers and polypharmacy also scored high. Deviation from evidence-based guidelines and patient privacy in the reception/waiting room were not perceived as risk factors by most of the GPs. Conclusion The views of GPs on safety and risk in primary care did not completely match those presented in published papers and policy documents. The GPs in the present study judged a broader range of factors than in previously published research on patient safety in primary care, including a poor doctor-patient relationship, to pose a potential threat to patient safety. Other risk factors such as infection prevention, deviation from guidelines and incident reporting were judged to be less relevant than by policy

    2007-07-01

    At present, the 10-year Periodic Safety Review(PSR) has been performing to confirm all the aspects of safety issues for all the operating plants in compliance with domestic nuclear law of article 23, subarticle 3. For each plant, in addition, Probabilistic Safety Assessment(PSA) and Severe Accident Management Guideline(SAMG) are being implemented and revised periodically to reflect the latest safety level according to principle fulfillment of severe accident policy statement. The assessment reports, as one of outcomes from these activities, are submitted into and reviewed by domestic regulatory body. During reviewing (in-office duty) and licensing (regulatory duty) process, a large number of outcomes of which most are the formal technical reports and licensing materials, are inevitably produced. Moreover, repeated review process over the plants can make them accumulated and produce a variety of documents additionally. This circumstance motivates to develop effective tool or system for the management of these reports and related technical documents for the future use in licensing process and for subsequent plant assessments. This paper presents the development status of Safety Assessment Information System(SAIS) which manages safety-related documents of PSR, PSA and SAMG for practical use for experienced engineers in charge of these areas.

    Safety analyses have the objective of contributing to two essential ingredients of a successful operation. The first is promoting the safety of the operation through worker involvement in information development (safety basis). The second is obtaining approval to conduct the operation (authorization). Typically these ingredients are assembled under separate programs covered by separate DOE requirements. DOE authorization relies on successful development of a document containing up to 21 topics written in terms and language suited to reviewers and approvers. Safety relies on successful training and procedures that convert the technical documented information into terms and language understandable to the worker. This separation can lead to successful incorporation of one ingredient independent of the other. At best, this separation may result in a safe but unauthorized operation; at worst, the separation may result in an unsafe operation authorized to proceed. This guide is based on experiences gained by contractors who have integrated rather than separated the safety and authorization. The short duration of ER/D&D activities, the uncertainties of hazards, and the publicly expressed desire for demonstrable progress in cleanup activities add emphasis to the need to integrate rather than separate and develop new programs. Experience-based information has been useful to workers, safety analysis practitioners, and reviewers in the following ways: (1) Acquiring or developing the needed information in a useful form; (2) Managing the uncertainties during activity development and operation; (3) Identifying the subset of applicable requirements for an activity; (4) Developing the appropriate level of documentation detail for a specific activity; and (5) Increasing the usefulness and use of safety analysis (ownership).

  9. Safety challenge increases with rapid drilling activity pace

    Energy Technology Data Exchange (ETDEWEB)

    Mowers, J.

    2000-05-01

    Safety practices in use by drilling companies in an effort to keep accidents on drilling platforms to the absolute minimum at a time when drilling activity is at its peak as a consequence of high oil and natural gas prices, is discussed. The likelihood of an increased rate of accidents is exacerbated by the fact that thousands of people left the industry during the downturn, and the sudden resurgence in drilling activity increased the number of 'greenhands' working on the rigs. There are pre-employment training courses offered at the Petroleum Industry Training Service (PITS) in Nisku, but most roughnecks, especially in the current busy environment are learning on the job, consequently, they do not have the luxury of practicing some of the key tasks, gradually building up speed, hence the need for being especially careful. Many companies have daily safety meetings, safety alert bulletins, safety courses of various descriptions designed by PITS and others, to keep workers talking and thinking about processes and procedures, about how to do things more safely. Fall protection, fall rescue for rig work, blowout prevention, hydrogen sulphide hazard and detection ('H{sub 2}S alive'), product labelling, material safety, fire safety are just some of the areas in which PITS have developed courses. All of them are designed to increase awareness about the dangers of accidents and to impart knowledge to deal with them when they occur. Industry Recommended Practices (IRPs) constitute another from of safety education. These are developed by volunteers from industry associations, government regulators and technical experts. Also included in the groups of experts are government health and safety personnel to ensure that IRPs meet legislative requirements.

    Undergraduate students were surveyed to assess their awareness of and interest in health and safety education. Out of 5258 questionnaires distributed among 66 colleges and universities in Taiwan, 4474 questionnaires were returned. The respondents were asked to provide demographic information and to respond to questions about a proposed college course in general occupational health and safety (OHS) and questions about 30 OHS topics. Their awareness and learning interest about each topic were evaluated on a 4-point scale. Statistical analysis of variance and logistic linear regression were performed. Only 13% of respondents had previously taken health and safety courses. More than 39% of respondents indicated that they would take general OHS courses if the courses were offered by their colleges. Student motivation to take OHS courses was apparently related to their experience in OHS coursework, their academic background, and their current learning interest in the 30 OHS topics. Students with natural science or engineering backgrounds tended to express strong interest in OHS topics and courses. In conclusion, implementing general health and safety education in college is recommended. In addition, developing an OHS course module system would meet student expectations, as courses would consider the learning interests and needs of students with different college majors.

  11. The safety attitudes of people who use multi-purpose recreation facilities as a physical activity setting.

    2011-06-01

    Multi-purpose recreation facilities (MPRFs) are a popular setting for physical activity and it is therefore important that they are safe for all patrons. However, the attitudes of MPRF users towards safety are a potential barrier to the success of injury prevention programmes implemented within MPRFs. This article reports a survey of the safety attitudes of over 700 users of four indoor MPRFs. Factor analysis of 12 five-point Likert scale statements showed that the attitudes clustered around three major dimensions - the importance of safety, the benefits of safety and the perceptions of injury risk. Together, these three dimensions accounted for 49% of the variability in the attitudes. More than 85% of respondents agreed/strongly agreed that: safety was an important aspect of physical activity participation; being injured affected enjoyment of physical activity; people should adopt appropriate safety measures for all physical activity; and individuals were responsible for their own safety. The MPRF users, particularly women and older people, were generally safety conscious, believed in adopting safety measures, and were willing to take responsibility for their own safety. Facility managers can be confident that if they provide evidence-based injury prevention interventions in these settings, then users will respond appropriately and adopt the promoted behaviours.

    2012-01-01

    Full Text Available Objective. To evaluate the association between safety from crime and physical activity among older adults. Methods. A population-based survey including 1,656 older adults (60+ years took place in Florianopolis, Brazil, in 2009-2010. Commuting and leisure time physical activity were assessed through the long version of the International Physical Activity Questionnaire. Perception of safety from crime was assessed using the Neighbourhood Environment Walkability Scale. Results. Perceiving the neighbourhood as safe during the day was related to a 25% increased likelihood of being active in leisure time (95% CI 1.02–1.53; general perception of safety was also associated with a 25% increase in the likelihood of being active in leisure time (95% CI 1.01–1.54. Street lighting was related to higher levels of commuting physical activity (prevalence ratio: 1.89; 95% CI 1.28–2.80. Conclusions. Safety investments are essential for promoting physical activity among older adults in Brazil.

    Bars of arbitrary shape made of a homogeneous anisotropic material are considered. In the general case, in their cross section, nonzero are all internal force factors (IFF) — three forces and three moments. The values of the IFF are known from solutions of the corresponding problem. The safety factor for the load-carrying capacity of the beams is determined by comparing the known vector R ∗ of IFF with the corresponding desired strength vector R in the IFF space.

    2013-01-01

    Full Text Available Abstract Background Several neighbourhood elements have been found to be related to leisure-time walking and cycling. However, the association with neighbourhood safety remains unclear. This study aimed to assess the association of neighbourhood-level safety with leisure-time walking and cycling among Dutch adults. Methods Data were derived from the national health survey (POLS 2006–2009, with valid data on 20046 respondents residing in 2127 neighbourhoods. Multilevel logistic regression models were used to examine the association between neighbourhood-level safety (general safety and specific safety components: physical disorder, social disorder, crime-related fear, traffic safety and residents’ engagement in outdoor leisure-time walking and cycling for at least 30 minutes per week. Results An increase in neighbourhood safety (both general safety and each of the safety components was significantly associated with an increase in leisure-time cycling participation. Associations were strongest for general safety and among older women. In the general population, neighbourhood safety was not significantly associated with leisure-time walking. However, among younger and older adult men and lower educated individuals, an increase in general safety was associated with a decrease in leisure-time walking participation. Conclusions In the Netherlands, neighbourhood safety appears to be related to leisure-time cycling but not to walking. Leisure-time cycling may best be encouraged by improving different safety components at once, rather than focusing on one safety aspect such as traffic safety. Special attention is needed for older women.

An interpretation of this statement may bring you to the conclusion that you should stop working in order to avoid risks. If the safety is the priority, work is not! This would be a misunderstanding and misinterpretation. One should understand that “working safely” or “operating safely” is the priority at CERN. CERN personnel are exposed to different hazards on many levels on a daily basis. However, risk analyses and assessments are done in order to limit the number and the gravity of accidents. For example, this process takes place each time you cross the road. The hazard is the moving vehicle, the stake is you and the risk might be the risk of collision between both. The same principle has to be applied during our daily work. In particular, keeping in mind the general principles of prevention defined in the late 1980s. These principles wer...

    The food industry has been under growing pressure to feed an exponentially increasing world population and challenged to meet rigorous food safety law and regulation. The plethora of media consumption has provoked consumer demand for safe, sustainable, organic, and wholesome products with "clean" labels. The application of active and intelligent packaging has been commercially adopted by food and pharmaceutical industries as a solution for the future for extending shelf life and simplifying production processes; facilitating complex distribution logistics; reducing, if not eliminating the need for preservatives in food formulations; enabling restricted food packaging applications; providing convenience, improving quality, variety and marketing features; as well as providing essential information to ensure consumer safety. This chapter reviews innovations of active and intelligent packaging which advance packaging technology through both scavenging and releasing systems for shelf life extension, and through diagnostic and identification systems for communicating quality, tracking and brand protection.

  1. Maximising harm reduction in early specialty training for general practice: validation of a safety checklist

    Full Text Available Abstract Background Making health care safer is a key policy priority worldwide. In specialty training, medical educators may unintentionally impact on patient safety e.g. through failures of supervision; providing limited feedback on performance; and letting poorly developed behaviours continue unchecked. Doctors-in-training are also known to be susceptible to medical error. Ensuring that all essential educational issues are addressed during training is problematic given the scale of the tasks to be undertaken. Human error and the reliability of local systems may increase the risk of safety-critical topics being inadequately covered. However adherence to a checklist reminder may improve the reliability of task delivery and maximise harm reduction. We aimed to prioritise the most safety-critical issues to be addressed in the first 12-weeks of specialty training in the general practice environment and validate a related checklist reminder. Methods We used mixed methods with different groups of GP educators (n = 127 and specialty trainees (n = 9 in two Scottish regions to prioritise, develop and validate checklist content. Generation and refinement of checklist themes and items were undertaken on an iterative basis using a range of methods including small group work in dedicated workshops; a modified-Delphi process; and telephone interviews. The relevance of potential checklist items was rated using a 4-point scale content validity index to inform final inclusion. Results 14 themes (e.g. prescribing safely; dealing with medical emergency; implications of poor record keeping; and effective & safe communication and 47 related items (e.g. how to safety-net face-to-face or over the telephone; knowledge of practice systems for results handling; recognition of harm in children were judged to be essential safety-critical educational issues to be covered. The mean content validity index ratio was 0.98. Conclusion A checklist was developed and

    To describe, explore, and compare organisational routines for repeat prescribing in general practice to identify contributors and barriers to safety and quality. Ethnographic case study. Four urban UK general practices with diverse organisational characteristics using electronic patient records that supported semi-automation of repeat prescribing. 395 hours of ethnographic observation of staff (25 doctors, 16 nurses, 4 healthcare assistants, 6 managers, and 56 reception or administrative staff), and 28 documents and other artefacts relating to repeat prescribing locally and nationally. Potential threats to patient safety and characteristics of good practice. Observation of how doctors, receptionists, and other administrative staff contributed to, and collaborated on, the repeat prescribing routine. Analysis included mapping prescribing routines, building a rich description of organisational practices, and drawing these together through narrative synthesis. This was informed by a sociological model of how organisational routines shape and are shaped by information and communications technologies. Results Repeat prescribing was a complex, technology-supported social practice requiring collaboration between clinical and administrative staff, with important implications for patient safety. More than half of requests for repeat prescriptions were classed as "exceptions" by receptionists (most commonly because the drug, dose, or timing differed from what was on the electronic repeat list). They managed these exceptions by making situated judgments that enabled them (sometimes but not always) to bridge the gap between the idealised assumptions about tasks, roles, and interactions that were built into the electronic patient record and formal protocols, and the actual repeat prescribing routine as it played out in practice. This work was creative and demanded both explicit and tacit knowledge. Clinicians were often unaware of this input and it did not feature in policy

    Three occupational safety and health (OSH) activities, one international and two national workshops, were documented as part of OSH activities conducted under the International Labor Organization/Korea Partnership Program in the year 2011-2012. This study aimed to provide information on what the three OSH activities were implemented and how they contributed to the improvement of OSH in Asian countries. The international workshop was useful for the participants to understand a variety of information on OSH as well as participatory action-oriented training (PAOT) approaches at the regional and global levels. The two national workshops were practical for participants to strengthen their knowledge and skills on the PAOT at the enterprise and national levels. The study shows that the three OSH activities contributed to the understanding of the participants on OSH and PAOT, and that the activities promoted the improvement of OSH across countries in Asia.

    Advanced vehicle safety systems have been widely introduced in transportation systems and are expected to enhance traffic safety. However, these technologies mainly focus on assisting individual vehicles that are equipped with them, and less effort has been made to identify the effect of vehicular technologies on the traffic stream. This study proposed a methodology to assess the effectiveness of active vehicle safety systems (AVSSs), which represent a promising technology to prevent traffic crashes and mitigate injury severity. The proposed AVSS consists of longitudinal and lateral vehicle control systems, which corresponds to the Level 2 vehicle automation presented by the National Highway Safety Administration (NHTSA). The effectiveness evaluation for the proposed technology was conducted in terms of crash potential reduction and congestion mitigation. A microscopic traffic simulator, VISSIM, was used to simulate freeway traffic stream and collect vehicle-maneuvering data. In addition, an external application program interface, VISSIM's COM-interface, was used to implement the AVSS. A surrogate safety assessment model (SSAM) was used to derive indirect safety measures to evaluate the effectiveness of the AVSS. A 16.7-km freeway stretch between the Nakdong and Seonsan interchanges on Korean freeway 45 was selected for the simulation experiments to evaluate the effectiveness of AVSS. A total of five simulation runs for each evaluation scenario were conducted. For the non-incident conditions, the rear-end and lane-change conflicts were reduced by 78.8% and 17.3%, respectively, under the level of service (LOS) D traffic conditions. In addition, the average delay was reduced by 55.5%. However, the system's effectiveness was weakened in the LOS A-C categories. Under incident traffic conditions, the number of rear-end conflicts was reduced by approximately 9.7%. Vehicle delays were reduced by approximately 43.9% with 100% of market penetration rate (MPR). These results

    Full Text Available Purpose: modern strategies of management of the organization require the formation of special management approaches based on the analysis of the mechanisms and processes of the organization of medical activities related to possible risks in activity of medical personnel. Based on international experience and own research the authors have identified features of a system of management of personnel risk in medical activities, examined approaches showing the sequence and contents of the main practical activities of the formation, maintenance and development of the system of management of personnel risks. Emphasized is the need for further research and implementation of the system of management of personnel risk in health care organizations. Study and assessment of personnel risks affecting the security of medical activities aimed at the development of the system of personnel risk management, development of a system of identification and monitoring of HR risk indicators with a purpose to improve institutional management and increase efficiency of activity of medical organizations. Methods: in the present study, the following methods were used: systemic approach, content analysis, methods of social diagnosis (questionnaires, interviews, comparative analysis, method of expert evaluations, method of statistical processing of information. Results: approaches to predict the occurrence and development of personnel risks have been reviewed and proposed. Conclusions and Relevance: patient safety is a global issue affecting countries at all levels of development. Each year, the WHO identifies a number of systemic and technical aspects and trends in the field of patient safety related to actions of medical workers. Existing imbalances in the staffing of the health system of the Russian Federation increase the probability of potential risks in medical practice. The personnel policy of healthcare of the Russian Federation requires further improvement and

    Background Randomized controlled trials consistently support the efficacy of antidepressants in treating youth with generalized anxiety disorder (GAD), although integrated examinations of efficacy, safety, and tolerability of psychotropic medications in GAD specifically are rare. With this in mind, we sought to describe the efficacy, safety and tolerability of psychopharmacologic interventions in youth with GAD. Methods Randomized, double-blind, placebo-controlled, prospective trials of psychopharmacologic interventions in youth with GAD were identified through a PubMed/Medline (1966–2015) search. Both authors manually reviewed trials and, to evaluate comparative efficacy and tolerability across medications, numbers needed to treat (NNT) (based on Pediatric Anxiety Rating Scale (PARS) remission criteria (PARS ≤8 [1]), and number needed to harm (NNH) for selected treatment-emergent adverse events (TEAEs) were calculated. Finally, treatment-emergent suicidality and taper-emergent/post-study adverse events are reported descriptively. Results Five trials that involved 1,186 patients and evaluated four medications were reviewed and efficacy data were extracted with regard to dimensional measures of anxiety. SSRI/SNRIs demonstrated efficacy in the reduction of anxiety symptoms with NNTs ranging from 2.8 to 9.3. TEAEs varied considerably between studies but tended to be mild and generally did not lead to discontinuation. Conclusions Data from five trials of SSRI/SNRI in youth with GAD, many of whom had co-occurring separation and social anxiety disorders, suggest superiority to placebo and favorable tolerability profiles.

    1985-09-01

    The General-Purpose Heat Source (GPHS) is a modular component of the radioisotope thermoelectric generator that will supply power for the Galileo and Ulysses (formerly ISPM) space missions. The GPHS provides power by transmitting the heat of (238)PuO2 (ALPHA)-decay to an array of thermoelectric elements. Because the possibility of an orbital abort always exists, the heat source was designed and constructed to minimize plutonia release in any accident environment. The Safety Verification Test (SVT) series was formulated to evaluate the effectiveness of GPHS plutonia containment after atmospheric reentry and Earth impact. The first report (covering SVT-1 through SVT-6) described the results of flat and side-on module impacts. This report describes module impacts at angles of 15(0) and 30(0).

  15. The Activity Chain Safety and Liveness Specification of Composite Web Services

    Science.gov (United States)

    Chen, Bo; Huang, Xiaomei

    Web service composition is most impressing method for development and deployment of e-business. Description and modeling the behavior requirements of composite Web services for users and verifying composite Web service compliance to specific requirements is an important key in design of services. But most work does not address the issue of how to model the requirements that the BPEL4WS processes are supposed to satisfy. The specifications in verification works are general temporal relation based on activity or scenario in essence. Distinguish with these work, we propose a novel concept of behavior specification based on activity chain in which granularity is between activity and scenario. Chain existence mode, chain absence mode are designed to express such behavioral requirements based on activity chain that is similar with safety or liveness specification based on activity respectively. Encode them on Labeled Transition System LTS and then give them exact operation semantics. Finally, an example is illustrated.

  18. Assessment of a Conceptual Flap System Intended for Enhanced General Aviation Safety

    Science.gov (United States)

    Campbell, Bryan A.; Carter, Melissa B.

    2017-01-01

    A novel multielement trailing-edge flap system for light general aviation airplanes was conceived for enhanced safety during normal and emergency landings. The system is designed to significantly reduce stall speed, and thus approach speed, with the goal of reducing maneuveringflight accidents and enhancing pilot survivability in the event of an accident. The research objectives were to assess the aerodynamic performance characteristics of the system and to evaluate the extent to which it provided both increased lift and increased drag required for the low-speed landing goal. The flap system was applied to a model of a light general aviation, high-wing trainer and tested in the Langley 12- Foot Low-Speed Wind Tunnel. Data were obtained for several device deflection angles, and component combinations at a dynamic pressure of 4 pounds per square foot. The force and moment data supports the achievement of the desired increase in lift with substantially increased drag, all at relatively shallow angles of attack. The levels of lift and drag can be varied through device deflection angles and inboard/outboard differential deflections. As such, it appears that this flap system may provide an enabling technology to allow steep, controllable glide slopes for safe rapid descent to landing with reduced stall speed. However, a simple flat-plate lower surface spoiler (LSS) provided either similar or superior lift with little impact on pitch or drag as compared to the proposed system. Higher-fidelity studies are suggested prior to use of the proposed system.

    The purpose of this study was to review the rate of adverse events after contrast medium administration in the general population and at-risk patients (renal impairment, heart failure (NYHA III or IV), hypotension or hypertension, coronary artery disease, previous reaction to contrast media, asthma and/or allergies, dehydration, diabetes mellitus, poor general condition) under daily practice conditions in a post-marketing surveillance study. Two hundred and ten radiologists conducted various X-ray examinations in 52,057 patients. To document the safety of iobitridol in routine use, all patients undergoing X-ray examinations were included. Exclusion criteria were contraindications listed in the locally approved summary of product characteristics. The adverse event rate was 0.96% (at-risk patients 1.39%); the rate of serious adverse events 0.044% in all patients (at-risk patients 0.057%). Adverse events occurred more often in women than in men (P<0.001). In patients who had previously reacted to a contrast medium, adverse events were reported in 3.43% with mild to moderate symptoms. In 47.76% of these patients, a premedication was administered. There was no difference in the frequency of adverse events and serious adverse events whether premedicated or not (P=0.311 and P=0.295, respectively). Iobitridol was well-tolerated in 99.04% of cases (at-risk patients 98.61%). (orig.)

    López Cortés, Luis F; Martínez, Esteban; von Wichmann, Miguel Ángel

    2013-06-01

    Currently available data on the safety and tolerability of rilpivirine come from the product information document, a phase IIb, dose-finding clinical trial (TMC278-C204), the phase III ECHO and THRIVE clinical trials, and the preliminary data from the STaR and SPIRIT clinical trials, with a total of 1,728 patients. The comparator has usually been efavirenz. All studies have found a lower incidence and severity of neuropsychiatric adverse effects, a better lipid profile, and a lower number of patients with subclinical transaminase elevation in patients treated with rilpivirine. However, because of the relatively low number of patients coinfected with hepatitis B or C virus, definitive conclusions cannot be drawn. Similarly, experience in patients with mild or moderate liver failure is limited and there are no safety data in patients with advanced liver failure.

    This paper documents the activities of the US-Japan exchange in the area of personnel safety at magnetic and laser fusion experiments. A near-miss event with a visiting scientist to the US in 1992 was the impetus for forming the Joint Working Group on Fusion Safety. This exchnge has been under way for over ten years and has provided many safety insights for both US and Japanese facility personnel at national institutes and at universities. The background and activities of the Joint Working Group are described, including the facilities that have been visited for safety walkthroughs, the participants from both countries, and the main safety issues examined during visits. Based on these visits, some operational safety ideas to enhance experiment safety are given. The near-term future plans of the Safety Monitor Joint Working group are also discussed.

    2007-11-01

    Full Text Available Abstract Background Research articles reporting positive findings in the fields of orthopedic and general surgery appear to be represented at a considerably higher prevalence in the peer-reviewed literature, compared to published studies on negative or neutral data. This "publication bias" may alter the balance of the available evidence-based literature and may affect patient safety in surgery by depriving important information from unpublished negative studies. Methods A comprehensive review of all published articles in a defined 7-year period was performed in 12 representative journals in the fields of orthopedic and general surgery. Every article published in all volumes of these journals between January 2000 and December 2006 was reviewed and rated by three investigators. Rating of articles was performed according to a uniform, standardized algorithm. All original articles were stratified into "positive", "negative" or "neutral", depending on the reported results. All non-original papers were excluded from analysis. Results A total of 30,197 publications were reviewed over a 7-year time-period. After excluding all non-original articles, a total of 16,397 original papers were included in the final analysis. Of these, 12,251 (74% articles were found to report positive findings, 2,709 (17% reported negative results, and 1,437 (9% were neutral. A similar publication pattern was found among all years and all journals analyzed. Altogether, 91% of all original papers reported significant data (positive or negative, whereas only 9% were neutral studies that did not report any significant findings. Conclusion There is a disproportionately high number of articles reporting positive results published in the surgical literature. A bias towards publishing positive data will systematically overestimate the clinical relevance of treatment effects by disregarding important information derived from unpublished negative studies. This "publication bias

Each module contains four /sup 238/PuO/sub 2/-fueled clads and generates 250 W/sub (t)/. Because a launch-pad or post-launch explosion is always possible, we need to determine the ability of GPHS fueled clads within a module to survive fragment impact. The bullet/fragment test series, part of the Safety Verification Test Plan, was designed to provide information on clad response to impact by a compact, high-energy, aluminum-alloy fragment and to establish a threshold value of fragment energy required to breach the iridium cladding. Test results show that a velocity of 555 m/s (1820 ft/s) with an 18-g bullet is at or near the threshold value of fragment velocity that will cause a clad breach. Results also show that an exothermic Ir/Al reaction occurs if aluminum and hot iridium are in contact, a contact that is possible and most damaging to the clad within a narrow velocity range. The observed reactions between the iridium and the aluminum were studied in the laboratory and are reported in the Appendix.

    The goal of this study was to propose a general numerical analysis methodology to evaluate the magnetic resonance imaging (MRI)-safety of active implants. Numerical models based on the finite element (FE) technique were used to estimate if the normal operation of an active device was altered during MRI imaging. An active implanted pump was chosen to illustrate the method. A set of controlled experiments were proposed and performed to validate the numerical model. The calculated induced voltages in the important electronic components of the device showed dependence with the MRI field strength. For the MRI radiofrequency fields, significant induced voltages of up to 20 V were calculated for a 0.3T field-strength MRI. For the 1.5 and 3.0OT MRIs, the calculated voltages were insignificant. On the other hand, induced voltages up to 11 V were calculated in the critical electronic components for the 3.0T MRI due to the gradient fields. Values obtained in this work reflect to the worst case situation which is virtually impossible to achieve in normal scanning situations. Since the calculated voltages may be removed by appropriate protection circuits, no critical problems affecting the normal operation of the pump were identified. This study showed that the proposed methodology helps the identification of the possible incompatibilities between active implants and MR imaging, and can be used to aid the design of critical electronic systems to ensure MRI-safety.

    To outline a structured approach for general surgery resident integration into institutional quality improvement and patient safety education and development. A strategic plan to address Accreditation Council for Graduate Medical Education (ACGME) Clinical Learning Environment Review assessments for resident integration into Quality Improvement and Patient Safety initiatives is described. Gundersen Lutheran Medical Foundation is an independent academic medical center graduating three categorical residents per year within an integrated multi-specialty health system serving 19 counties over 3 states. The quality improvement and patient safety education program includes a formal lecture series, online didactic sessions, mandatory quality improvement or patient safety projects, institutional committee membership, an opportunity to serve as a designated American College of Surgeons National Surgical Quality Improvement Project and Quality in Training representative, mandatory morbidity and mortality conference attendance and clinical electives in rural surgery and international settings. Structured education regarding and participation in quality improvement and patient safety programs are able to be accomplished during general surgery residency. The long-term outcomes and benefits of these strategies are unknown at this time and will be difficult to measure with objective data. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

    Fire Safety – Essential for a particle detector The CMS detector is a marvel of high technology, one of the most precise particle measurement devices we have built until now. Of course it has to be protected from external and internal incidents like the ones that can occur from fires. Due to the fire load, the permanent availability of oxygen and the presence of various ignition sources mostly based on electricity this has to be addressed. Starting from the beam pipe towards the magnet coil, the detector is protected by flooding it with pure gaseous nitrogen during operation. The outer shell of CMS, namely the yoke and the muon chambers are then covered by an emergency inertion system also based on nitrogen. To ensure maximum fire safety, all materials used comply with the CERN regulations IS 23 and IS 41 with only a few exceptions. Every piece of the 30-tonne polyethylene shielding is high-density material, borated, boxed within steel and coated with intumescent (a paint that creates a thick co...

    The Food and Drug Administration (FDA) is amending the biologics regulations by removing the general safety test (GST) requirements for biological products. FDA is finalizing this action because the existing codified GST regulations are duplicative of requirements that are also specified in biologics license applications (BLAs), or are no longer necessary or appropriate to help ensure the safety, purity, and potency of licensed biological products. FDA is taking this action as part of its retrospective review of its regulations to promote improvement and innovation, in response to the Executive order.

    Motility-induced phase separation (MIPS) arises generically in fluids of self-propelled particles when interactions lead to a kinetic slowdown at high density. Starting from a continuum description of diffusive scalar active matter, we give a general prescription for phase equilibria that amounts, at a hydrodynamics scale, to extremalizing a generalized free energy. We illustrate our approach on two well known models: self-propelled particles interacting either through a density-dependent pro...

    Objective Patients commonly show signs and symptoms of deterioration for hours or days before cardiorespiratory arrest. Rapid response teams (RRT) were created to improve recognition and response to patient deterioration in these situations. Activation criteria include vital signs or 'general concern' by a clinician or family member. The general concern criterion for RRT activation accounts for nearly one-third of all RRT activity, and although it is well established that communication deficits between staff can contribute to poorer outcomes for patients, there is little evidence pertaining to communication and its effects on the general concern RRT activation. Thus, the aim of the present study was to develop a substantive grounded theory related to the communication process between clinicians that preceded the activation of an RRT when general concern criterion was used.Methods Qualitative grounded theory involved collection of three types of data details namely personal notes from participants in focus groups with white board notes from discussions and audio recordings of the focus groups sessions. Focus groups were conducted with participants exploring issues associated with clinician communication and how it related to the activation of an RRT using the general concern criterion.Results The three main phases of coding (i.e. open, axial and selective coding) analysis identified 322 separate open codes. The strongest theme contributed to a theory of ineffective communication and decreased psychological safety, namely that 'In the absence of effective communication there is a subsequent increase in anxiety, fear or concern that can be directly attributed to the activation of an RRT using the 'general concern' criterion'. The RRT filled cultural and process deficiencies in the compliance with an escalation protocol. Issues such as 'not for resuscitation documentation' and 'inability to establish communication with and between medical or nursing personnel' rated

    de Jonge, J; van Trijp, J C M; van der Lans, I A; Renes, R J; Frewer, L J

    2008-09-01

    This paper investigates the relationship between general consumer confidence in the safety of food and consumer trust in institutions and organizations. More specifically, using a decompositional regression analysis approach, the extent to which the strength of the relationship between trust and general confidence is dependent upon a particular food chain actor (for example, food manufacturers) is assessed. In addition, the impact of specific subdimensions of trust, such as openness, on consumer confidence are analyzed, as well as interaction effects of actors and subdimensions of trust. The results confirm previous findings, which indicate that a higher level of trust is associated with a higher level of confidence. However, the results from the current study extend on previous findings by disentangling the effects that determine the strength of this relationship into specific components associated with the different actors, the different trust dimensions, and specific combinations of actors and trust dimensions. The results show that trust in food manufacturers influences general confidence more than trust in other food chain actors, and that care is the most important trust dimension. However, the contribution of a particular trust dimension in enhancing general confidence is actor-specific, suggesting that different actors should focus on different trust dimensions when the purpose is to enhance consumer confidence in food safety. Implications for the development of communication strategies that are designed to regain or maintain consumer confidence in the safety of food are discussed.

    Full Text Available Abstract Background Due to the inconsistent findings of prior studies, we explored the association of perceived safety and police-recorded crime measures with physical activity. Methods The study included 818 Chicago participants of the Multiethnic Study of Atherosclerosis 45 to 84 years of age. Questionnaire-assessed physical activity included a transport walking; b leisure walking; and c non-walking leisure activities. Perceived safety was assessed through an interviewer-administered questionnaire. Police-recorded crime was assessed through 2-year counts of selected crimes (total and outdoor incivilities, criminal offenses, homicides per 1000 population. Associations were examined using generalized estimating equation logistic regression models. Results Perceiving a safer neighborhood was positively associated with transport walking and perceiving lower violence was associated with leisure walking. Those in the lowest tertile of total or outdoor incivilities were more likely to report transport walking. Models with both perceived safety and police-recorded measures of crime as independent variables had superior fit for both transport walking and leisure walking outcomes. Neither perceived safety nor police-recorded measures of crime were associated with non-walking leisure activity. Conclusions Perceived and police-recorded measures had independent associations with walking and both should be considered in assessing the impact of neighborhood crime on physical activity.

    A novel active backstepping control method is presented for synchronizing two identical Rossler hyperchaotic systems with each other, and extended to achieve the generalized synchronization of the Chua chaotic system with the Rossler hyperchaotic system. It is a systematic design approach and consists of a recursive procedure interlacing the choice of a Lyapunov function with the design of active control. In particular, this technique gives flexibility in constructing a control law. Numerical experiments verify the feasibility and effectiveness of the proposed control technique.

    In conventional system reliability calculations, each component may be in the Operable state or the Under Repair state. These calculations derive system unavailability, or the probability of the system's being down for repairs. By introducing a third component state between Operable and Under Repair - namely, Defective, But Defect Undetected - the methods developed in this report enable system safety projections to be made in addition to availability projections. Also provided is a mechanism for computing the effect of inspection schedules on both safety and availability. A Reliability and Safety Program (RASP) is detailed which performs these computations and also calculates costs for system inspections and repairs. RASP is applied to a simplified wind energy conversion system example.

    Full Text Available Studies of neighborhood safety and physical activity have typically neglected to consider the youth's peer context as a modifier of these relationships. This study fills this gap in testing the independent and interactive effects of perceived neighborhood safety and time spent with friends and peers on young adolescents' physical activity and sedentary behavior. Participants (N = 80; ages 13–17 completed the Pedestrian/Traffic Safety and Crime Safety subscales of the adolescent version of the Neighborhood Environment Walkability Scale (NEWS. An experience sampling methodology was used to assess sedentary behaviors/screen time and the social context in which physical activity and sedentary time/behavior occurred. Physical activity was assessed via accelerometry. Multilevel models were used to estimate the relationships between predictors (neighborhood safety and social context and outcomes (physical activity and sedentary time/behavior. Frequency of peer/friend interactions moderated the relationships between neighborhood safety and adolescents' physical activity and sedentary behavior. Specifically, physical activity was more strongly influenced by neighborhood safety among adolescents who reported spending less time with peers and friends than among those who reported frequent peer interactions. Among youths who perceived that their neighborhoods were safer, spending more time with friends and peers was related to greater engagement in sedentary activities, whereas this was not the case among adolescents who perceived that their neighborhoods were less safe. The peer social context moderates the relationship between perceived neighborhood safety and adolescents' physical activity and sedentary behavior. Improving social interactions at the individual level within neighborhoods may decrease concerns of safety.

    Assumptions about the economics of making a system safe are usually not explicitly stated in industrial and software models of safety-critical systems. These assumptions span a wide spectrum of economic tradeoffs with respect to resources expended to make a system safe. The missing component in these models that is necessary for capturing the effect of economic tradeoffs is risk. A qualitative risk-based software safety model is proposed that combines features of industrial and software systems safety models. The risk-based model provides decision makers with a basis for performing cost-benefit analyses of software safety-related activities.

    Recent research has demonstrated that knowledge of real-world eventsplays an important role inguiding online language comprehension. The present study addresses the scope of event knowledge activation during the course of comprehension, specifically investigating whether activation is limited to those knowledge elements that align with the local linguistic context.The present study addresses this issue by analyzing event-related brain potentials (ERPs) recorded as participants read brief scenariosdescribing typical real-world events. Experiment 1 demonstratesthat a contextually anomalous word elicits a reduced N400 if it is generally related to the described event, even when controlling for the degree of association of this word with individual words in the preceding context and with the expected continuation. Experiment 2 shows that this effect disappears when the discourse context is removed.These findings demonstrate that during the course of incremental comprehension, comprehenders activate general knowledge about the described event, even at points at which this knowledge would constitute an anomalous continuation of the linguistic stream. Generalized event knowledge activationcontributes to mental representations of described events, is immediately available to influence language processing, and likely drives linguistic expectancy generation.

    2017-01-18

    The widespread adoption of health information technology (HIT) has led to new patient safety hazards that are often difficult to identify. Patient safety event reports, which are self-reported descriptions of safety hazards, provide one view of potential HIT-related safety events. However, identifying HIT-related reports can be challenging as they are often categorized under other more predominate clinical categories. This challenge of identifying HIT-related reports is exacerbated by the increasing number and complexity of reports which pose challenges to human annotators that must manually review reports. In this paper, we apply active learning techniques to support classification of patient safety event reports as HIT-related. We evaluated different strategies and demonstrated a 30% increase in average precision of a confirmatory sampling strategy over a baseline no active learning approach after 10 learning iterations.

    This paper presents an application of global sensitivity analysis for system safety analysis of reciprocating aircraft engine.Compared with local sensitivity analysis results,global sensitivity analysis could provide more information on parameter interactions,which are significant in complex system safety analysis.First,a deterministic aviation reciprocating engine thermodynamics model is developed and parameters of interest are defined as random variables.Then,samples are generated by Monte Carlo method for the parameters used in engine model on the basis of definition of factor distribution.Eventually,results from engine model are generated and importance indices are calculated.Based on the analysis results,design is improved to satisfy the airworthiness requirements.The results reveal that by using global sensitivity analysis,the parameters could be ranked with respect to their importance,including first order indices and total sensitivity indices.By reducing the uncertainty of parameters and adjusting the range of inputs,safety criteria would be satisfied.

    2001-03-01

    In the 1920s, the availability of piezoelectric materials and electronic devices made it possible to produce ultrasound (US) in water at high amplitudes, so that it could be detected after propagation through large distances. Laboratory experiments with this new mechanical form of radiation showed that it was capable of producing an astonishing variety of physical, chemical and biologic effects. In this review, the early findings on bioeffects are discussed, especially those from experiments done in the first few decades, as well as the concepts employed in explaining them. Some recent findings are discussed also, noting how the old and the new are related. In the first few decades, bioeffects research was motivated partly by curiosity, and partly by the wish to increase the effectiveness and ensure the safety of therapeutic US. Beginning in the 1970s, the motivation has come also from the need for safety guidelines relevant to diagnostic US. Instrumentation was developed for measuring acoustic pressure in the fields of pulsed and focused US employed, and standards were established for specifying the fields of commercial equipment. Critical levels of US quantities were determined from laboratory experiments, together with biophysical analysis, for bioeffects produced by thermal and nonthermal mechanisms. These are the basis for safety advice and guidelines recommended or being considered by national, international, professional and governmental organizations.

    Domestic violence and abuse (DVA) and child safeguarding are interlinked problems, impacting on all family members. Documenting in electronic patient records (EPRs) is an important part of managing these families. Current evidence and guidance, however, treats DVA and child safeguarding separately. This does not reflect the complexity clinicians face when documenting both issues in one family. To explore how and why general practice clinicians document DVA in families with children. A qualitative interview study using vignettes with GPs and practice nurses (PNs) in England. Semi-structured telephone interviews with 54 clinicians (42 GPs and 12 PNs) were conducted across six sites in England. Data were analysed thematically using a coding frame incorporating concepts from the literature and emerging themes. Most clinicians recognised DVA and its impact on child safeguarding, but struggled to work out the best way to document it. They described tensions among the different roles of the EPR: a legal document; providing continuity of care; information sharing to improve safety; and a patient-owned record. This led to strategies to hide information, so that it was only available to other clinicians. Managing DVA in families with children is complex and challenging for general practice clinicians. National integrated guidance is urgently needed regarding how clinicians should manage the competing roles of the EPR, while maintaining safety of the whole family, especially in the context of online EPRs and patient access. © British Journal of General Practice 2017.

    Full Text Available Context: A better understanding of medication safety ensures better health state among healthcare consumers. Aim: The study aims to assess general public awareness toward issues related to medication safety. Settings and Design: A cross-sectional study was conducted among general public selected conveniently in the state of Penang, Malaysia. Materials and methods: A total of 500 respondents were approached and 476 consumers participated in the survey giving a response rate of 95.2%. Statistical analysis: Data were analyzed by using SPSS version 12.0 and descriptive statistics were reported where appropriate. Results: Majority of the respondents (n=292, 61.3% stated that they were well aware of the possible side effects of their current medications. A total of 196 respondents (41.17% believed that all medicines registered in Malaysia are safe to use as these medicines have no side effects. About 40.33% (n=192 of the respondents claimed that they share their unused medicines with family and friends who are having similar illness. Majority of respondents 57.7% (n=275 were satisfied with the drug information provided by the healthcare professionals. This study also found that more than 80% of the respondents (n=409 did report that they read the labels of their medication before using. Conclusions: In this study, it was revealed that there is a moderate level of public knowledge regarding medication safety. It is evident that public underestimates the risk of their medications. There is a general lack of awareness and understanding among the public especially toward side effects.

    Full Text Available Abstract Background Anxiety is relatively common in depression and capable of modifying the severity and course of depression. Yet our understanding of how anxiety modulates frontal and limbic activation in depression is limited. Methods We used functional magnetic resonance imaging and two emotional information processing tasks to examine frontal and limbic activation in ten patients with major depression and comorbid with preceding generalized anxiety (MDD/GAD and ten non-depressed controls. Results Consistent with prior studies on depression, MDD/GAD patients showed hypoactivation in medial and middle frontal regions, as well as in the anterior cingulate, cingulate and insula. However, heightened anxiety in MDD/GAD patients was associated with increased activation in middle frontal regions and the insula and the effects varied with the type of emotional information presented. Conclusions Our findings highlight frontal and limbic hypoactivation in patients with depression and comorbid anxiety and indicate that anxiety level may modulate frontal and limbic activation depending upon the emotional context. One implication of this finding is that divergent findings reported in the imaging literature on depression could reflect modulation of activation by anxiety level in response to different types of emotional information.

    The number of ions required to drive substrate transport through a secondary active transporter determines the protein's ability to create a substrate gradient, a feature essential to its physiological function, and places fundamental constraints on the transporter's mechanism. Stoichiometry is known for a wide array of mammalian transporters, but, due to a lack of readily available tools, not for most of the prokaryotic transporters for which high-resolution structures are available. Here, we describe a general method for using radiolabeled substrate flux assays to determine coupling stoichiometries of electrogenic secondary active transporters reconstituted in proteoliposomes by measuring transporter equilibrium potentials. We demonstrate the utility of this method by determining the coupling stoichiometry of VcINDY, a bacterial Na(+)-coupled succinate transporter, and further validate it by confirming the coupling stoichiometry of vSGLT, a bacterial sugar transporter. This robust thermodynamic method should be especially useful in probing the mechanisms of transporters with available structures.

    2016-01-01

    The combination of laterally activating and inhibiting feedbacks is well known to spontaneously generate spatial organization. It was introduced by Gierer and Meinhardt as an extension of Turing's great insight that two reacting and diffusing chemicals can spontaneously drive spatial morphogenesis per se. In this study, we develop an accessible nonlinear and discrete probabilistic model to study simple generalizations of lateral activation and inhibition. By doing so, we identify a range of modes of morphogenesis beyond the familiar Turing-type modes; notably, beyond stripes, hexagonal nets, pores and labyrinths, we identify labyrinthine highways, Kagome lattices, gyrating labyrinths and multi-colour travelling waves and spirals. The results are discussed within the context of Turing's original motivating interest: the mechanisms which underpin the morphogenesis of living organisms. PMID:27170648

    2015-11-01

    The article explores the issues concerning safety enhancement of pipeline active fault crossing on Sakhalin Island. Based on the complexity and analysis results, all the faults crossed by pipeline system are classified into five categories - from very simple faults to extremely complex ones. The pipeline fault crossing design is developed in accordance with the fault category. To enhance pipeline safety at fault crossing, a set of methods should be applied: use of pipes of different safety classes and special trench design in accordance with soil permeability characteristics.

    Full Text Available Abstract Background Significant event analysis (SEA is promoted as a team-based approach to enhancing patient safety through reflective learning. Evidence of SEA participation is required for appraisal and contractual purposes in UK general practice. A voluntary educational model in the west of Scotland enables general practitioners (GPs and doctors-in-training to submit SEA reports for feedback from trained peers. We reviewed reports to identify the range of safety issues analysed, learning needs raised and actions taken by GP teams. Method Content analysis of SEA reports submitted in an 18 month period between 2005 and 2007. Results 191 SEA reports were reviewed. 48 described patient harm (25.1%. A further 109 reports (57.1% outlined circumstances that had the potential to cause patient harm. Individual 'error' was cited as the most common reason for event occurrence (32.5%. Learning opportunities were identified in 182 reports (95.3% but were often non-specific professional issues not shared with the wider practice team. 154 SEA reports (80.1% described actions taken to improve practice systems or professional behaviour. However, non-medical staff were less likely to be involved in the changes resulting from event analyses describing patient harm (p Conclusion The study provides some evidence of the potential of SEA to improve healthcare quality and safety. If applied rigorously, GP teams and doctors in training can use the technique to investigate and learn from a wide variety of quality issues including those resulting in patient harm. This leads to reported change but it is unclear if such improvement is sustained.

    Pharmacists by their training have the competences and skills to promote safe use of medicines which is an essential component of patient safety. This study explored the perceptions of hospital pharmacists' role in medication safety in Ghana, identified their attendant challenges and ways of enhancing such roles in the future. A self-administered questionnaire was delivered to 200 pharmacists selected conveniently from the 10 regions of Ghana. Questions in the questionnaire were based on a systematic literature review that had catalogued and summarised all the activities of hospital pharmacists related to medication safety. A total of 176 (88% response rate) questionnaires were completed and returned. Almost all pharmacists (97.7%) believed that they were involved in medication safety activities in their daily routine. The frequently performed activities were counselling of out-patient (91.8%), training pharmacy and other clinical students (72.2%), reporting on medication errors (70%), and reconciling medications (69.2%). The mean weekly time spent on the activities ranged from 6.5 to 19.8 hours. Participants who had clinical pharmacy related additional qualifications (χ2 = 37.749; p = 0.049) and worked in tertiary care hospitals (χ2 = 26.6; p = 0.377) undertook more medication safety activities than those without. The cited challenges faced by participants included inadequate time available (62.7%), spending most time in managerial activities (47.3%), lack of formal structures of engagement (43.8%), lack of motivation by superiors (34.9%), and no formal schedule by supervisor (32%). Only 7.7% stated they lack interest in performing those activities. Pharmacists undertake many medication safety activities routinely that they perceive to have impact on patient care outcomes. Restructuring of their managerial roles will contribute to freeing time for pharmacists to engage more in those activities.

    2003-09-01

    The Joint European Torus (JET) Facilities Active Gas Handling System (AGHS) comprises ten interconnected processing sub-systems that supply, process and recover tritium from gases used in the JET Machine. Operations require a diverse range of process instrumentation to carry out a multiplicity of monitoring and control tasks and approximately 500 process variables are measured. The different types and application of process instruments are presented with specially adapted or custom-built versions highlighted. Forming part of the Safety Case for tritium operations, a dedicated hardwired interlock and alarm system provides an essential safety function. In the event of failure modes, each hardwired interlock will back-up software interlocks and shutdown areas of plant to a failsafe condition. Design of the interlock and alarm system is outlined and general methodology described. Practical experience gained during plant operations is summarised and the methods employed for routine functional testing of essential instrument systems explained.

    Full Text Available Glutarimides, 2,6-dioxopiperidines are compounds that rarely occur in natural sources, but so far isolated ones exert widespread pharmacological activities, which makes them valuable as potential pharmacotherapeutics. Glutarimides act as androgen receptor antagonists, anti-inflammatory, anxiolytics, antibacterials, and tumor suppressing agents. Some synthetic glutarimide derivatives are already in use as immunosuppressive and sedative (e.g., thalidomide or anxiolytics (buspirone drugs. The wide applicability of this class of compounds, justify the interest of scientists to explore new pathways for its syntheses. General methods for synthesis of six-membered imide ring, are presented in this paper. These methods include: a reaction of dicarboxylic acids with ammonia or primary amine, b reactions of cyclization: amido-acids, diamides, dinitriles, nitrilo-acids, amido-nitriles, amido-esters, amidoacyl-chlorides or diacyl-chlorides, c adition of carbon-monoxide on a,b-unsaturated amides, d oxidation reactions, e Michael adition of active methylen compounds on methacrylamide or conjugated amides. Some of the described methods are used for closing glutarimide ring in syntheses of farmacological active compounds sesbanimide and aldose reductase inhibitors (ARI. Analyses of the geometry, as well as, the spectroscopic analyses (NMR and FT-IR of some glutarimides are presented because of their broad spectrum of pharmacological activity. To elucidate structures of glutarimides, geometrical parameters of newly synthesized tert-pentyl-1-benzyl-4-methyl-glutarimide-3-carboxylate (PBMG are analyzed and compared with the experimental data from X-ray analysis for glutarimide. Moreover, molecular electrostatic potential (MEP surface which is plotted over the optimized geometry to elucidate the reactivity of PBMG molecule is analyzed. The electronic properties of glutarimide derivatives are explained on the example of thalidomide. The Frontier Molecular Orbital

    This Department of Energy (DOE) technical standard (referred to as the Standard) provides guidance for integrating and enhancing worker, public, and environmental protection during facility disposition activities. It provides environment, safety, and health (ES and H) guidance to supplement the project management requirements and associated guidelines contained within DOE O 430.1A, Life-Cycle Asset Management (LCAM), and amplified within the corresponding implementation guides. In addition, the Standard is designed to support an Integrated Safety Management System (ISMS), consistent with the guiding principles and core functions contained in DOE P 450.4, Safety Management System Policy, and discussed in DOE G 450.4-1, Integrated Safety Management System Guide. The ISMS guiding principles represent the fundamental policies that guide the safe accomplishment of work and include: (1) line management responsibility for safety; (2) clear roles and responsibilities; (3) competence commensurate with responsibilities; (4) balanced priorities; (5) identification of safety standards and requirements; (6) hazard controls tailored to work being performed; and (7) operations authorization. This Standard specifically addresses the implementation of the above ISMS principles four through seven, as applied to facility disposition activities.

    The activities of the joint NASA/DOE/DOD Nuclear Propulsion Program Technical Panels have been used as the basis for the current development of safety policies and requirements for the Space Exploration Initiatives (SEI) Nuclear Propulsion Technology development program. The Safety Division of the NASA Office of Safety and Mission Quality has initiated efforts to develop policies for the safe use of nuclear propulsion in space through involvement in the joint agency Nuclear Safety Policy Working Group (NSPWG), encouraged expansion of the initial policy development into proposed programmatic requirements, and suggested further expansion into the overall risk assessment and risk management process for the NASA Exploration Program. Similar efforts are underway within the Department of Energy to ensure the safe development and testing of nuclear propulsion systems on Earth. This paper describes the NASA safety policy related to requirements for the design of systems that may operate where Earth re-entry is a possibility. The expected plan of action is to support and oversee activities related to the technology development of nuclear propulsion in space, and support the overall safety and risk management program being developed for the NASA Exploration Program.

    Studies evaluating the impact of modifiable lifestyle factors on cognition offer potential insights into sources of cognitive aging variability. Recently, we reported an association between extent of musical instrumental practice throughout the life span (greater than 10 years) on preserved cognitive functioning in advanced age. These findings raise the question of whether there are training-induced brain changes in musicians that can transfer to non-musical cognitive abilities to allow for compensation of age-related cognitive declines. However, because of the relationship between engagement in general lifestyle activities and preserved cognition, it remains unclear whether these findings are specifically driven by musical training or the types of individuals likely to engage in greater activities in general. The current study controlled for general activity level in evaluating cognition between musicians and nomusicians. Also, the timing of engagement (age of acquisition, past versus recent) was assessed in predictive models of successful cognitive aging. Seventy age and education matched older musicians (>10 years) and non-musicians (ages 59-80) were evaluated on neuropsychological tests and general lifestyle activities. Musicians scored higher on tests of phonemic fluency, verbal working memory, verbal immediate recall, visuospatial judgment, and motor dexterity, but did not differ in other general leisure activities. Partition analyses were conducted on significant cognitive measures to determine aspects of musical training predictive of enhanced cognition. The first partition analysis revealed education best predicted visuospatial functions in musicians, followed by recent musical engagement which offset low education. In the second partition analysis, early age of musical acquisition (memory in musicians, while analyses for other measures were not predictive. Recent and past musical activity, but not general lifestyle activities, predicted variability

Fluoxetine, a selective inhibitor of serotonin reuptake (SSRI, is widely utilized in the management of GAD in clinical practice despite the lack of strong evidence. This article reviews fluoxetine trials to investigate fluoxetine's efficacy and tolerability in Chinese patients with GAD. Methods: A literature review was conducted using the following databases up to and including April 2013: Chinese BioMedical Literature, China National Knowledge Infrastructure, EMBASE, MEDLINE, and PsycINFO. We selected clinical studies that utilized fluoxetine for GAD in which all participants were Chinese. Results: Fifteen open-label, non-placebo trials were identified and analyzed; eleven anxiolytics were compared with fluoxetine separately. Short-term efficacy of fluoxetine had been established in these open-label, head-to-head controlled trials. Fluoxetine had rapid onset of action (approximately 1–2 weeks and seemed to be effective in maintenance treatment. Fluoxetine was generally well-tolerated with the most common side effect of dry month and nausea. Compared to other anxiolytic agents, fluoxetine was equivalent with all of the comparative anxiolytics in terms of efficacy except mirtazapine which showed conflicting results with fluoxetine in two studies. In terms of side effects, fluoxetine was better tolerated than diazepam, doxepine, and amitriptyline, less tolerated than escitalopram, and had similar tolerability with duloxetine as well as alprazolam. Conclusion: Given the high risk of bias of the included studies, the overall small sample

    Recent safety issues involving non-active implantable medical devices (NAIMDs) have highlighted the need for better pre-market and post-market evaluation. Some stakeholders have argued that certain features of medicine safety evaluation should also be applied to medical devices. Our objectives were to compare the current processes and methodologies for the assessment of NAIMD safety profiles with those for medicines, identify potential gaps, and make recommendations for the adoption of new methodologies for the ongoing benefit-risk monitoring of these devices throughout their entire life cycle. A literature review served to examine the current tools for the safety evaluation of NAIMDs and those for medicines. We searched MEDLINE using these two categories. We supplemented this search with Google searches using the same key terms used in the MEDLINE search. Using a comparative approach, we summarized the new product design, development cycle (preclinical and clinical phases), and post-market phases for NAIMDs and drugs. We also evaluated and compared the respective processes to integrate and assess safety data during the life cycle of the products, including signal detection, signal management, and subsequent potential regulatory actions. The search identified a gap in NAIMD safety signal generation: no global program exists that collects and analyzes adverse events and product quality issues. Data sources in real-world settings, such as electronic health records, need to be effectively identified and explored as additional sources of safety information, particularly in some areas such as the EU and USA where there are plans to implement the unique device identifier (UDI). The UDI and other initiatives will enable more robust follow-up and assessment of long-term patient outcomes. The safety evaluation system for NAIMDs differs in many ways from those for drugs, but both systems face analogous challenges with respect to monitoring real-world usage. Certain features

    Safety coaching interventions have become a common feature in the safety critical offshore working environments of the North Sea. Whilst the beneficial impact of coaching as an organizational tool has been evidenced, there remains a question specifically over the use of safety coaching and its impact on behavioural change and producing safe working practices. A series of 24 semi-structured interviews were conducted with three groups of experts in the offshore industry: safety coaches, offshore managers and HSE directors. Using a thematic analysis approach, several significant themes were identified across the three expert groups including connecting with and creating safety ownership in the individual, personal significance and humanisation, ingraining safety and assessing and measuring a safety coach's competence. Results suggest clear utility of safety coaching when applied by safety coaches with appropriate coach training and understanding of safety issues in an offshore environment. The current work has found that the use of safety coaching in the safety critical offshore oil and gas industry is a powerful tool in managing and promoting a culture of safety and care.

  14. Engineer Ethics Education that Treated Safety Problem to Promote Development of General Human Competence and Independent Engineer

    Hotta, Genji

    The human race came to expect the engineer‧s international activity by an international extension of the risk. The engineer should provide with “Overall ability” and “Independent ability” to answer the demand of the society. The engineer ethics education is effective to the acquisition of the ability that the society demands. Because the engineer ethics education teaches the engineer to develop “Ethics action as the individual” to “Ethics activity as the enterprise” . In the point of development of the comprehensive capacity, it can be said that the engineer ethics education is training that supports the action power that accomplishes the social responsibility. However, it is easy to make the engineer ethics education a polite fiction. Then, we propose to take the safety problem to the ethics education for the prevention of making to the polite fiction of the education.

    The General-Purpose Heat Source(GPHS) provides power for space missions by transmitting the heat of /sup 238/PuO/sub 2/ decay to thermoelectric elements. Because of the inevitable return of certain aborted missions, the heat source must be designed and constructed to survive both re-entry and Earth impact. The Design Iteration Test (DIT) series is part of an ongoing test program. In the third test (DIT-3), a full GPHS module was impacted at 58 m/s and 930/sup 0/C. The module impacted the target at an angle of 30/sup 0/ to the pole of the large faces. The four capsules used in DIT-3 survived impact with minimal deformation; no internal cracks other than in the regions indicated by Savannah River Plant (SRP) preimpact nondestructive testing were observed in any of the capsules. The 30/sup 0/ impact orientation used in DIT-3 was considerably less severe than the flat-on impact utilized in DIT-1 and DIT-2. The four capsules used in DIT-1 survived, while two of the capsules used in DIT-2 breached; a small quantity (approx. = 50 ..mu..g) of /sup 238/PuO/sub 2/ was released from the capsules breached in the DIT-2 impact. All of the capsules used in DIT-1 and DIT-2 were severely deformed and contained large internal cracks. Postimpact analyses of the DIT-3 test components are described, with emphasis on weld structure and the behavior of defects identified by SRP nondestructive testing.

These technologies include an Analytical Methods element for neutron transport as well as the development of sensitivity/uncertainty methods, the performance of Critical Experiments, evaluation and qualification of experiments as Benchmarks, and a comprehensive Nuclear Data program coordinated by the NCSP Nuclear Data Advisory Group (NDAG). The NDAG gathers and evaluates differential and integral nuclear data, identifies deficiencies, and recommends priorities on meeting DOE criticality safety needs to the NCSP Criticality Safety Support Group (CSSG). Then the NDAG identifies the required resources and unique capabilities for meeting these needs, not only for performing measurements but also for data evaluation with nuclear model codes as well as for data processing for criticality safety applications. The NDAG coordinates effort with the leadership of the National Nuclear Data Center, the Cross Section Evaluation Working Group (CSEWG), and the Working Party on International Evaluation Cooperation (WPEC) of the OECD/NEA Nuclear Science Committee. The overall objective is to expedite the issuance of new data and methods to the DOE criticality safety user. This paper describes these activities in detail, with examples based upon special studies being performed in support of criticality safety for a variety of DOE operations.

    Full Text Available In this paper, we introduce a new type of information-theoretic method called “information-theoretic active SOM”, based on the self-organizing maps (SOM for training multi-layered neural networks. The SOM is one of the most important techniques in unsupervised learning. However, SOM knowledge is sometimes ambiguous and cannot be easily interpreted. Thus, we introduce the information-theoretic method to produce clearer and interpretable representations. The present method extends this information-theoretic approach into supervised learning. The main contribution can be summarized by three points. First, it is shown that clear representations by the information-theoretic method can be effective in training supervised learning. Second, the method is sufficiently simple where there are two separated components, namely, information maximization and error minimization component. Usually, two components are mixed in one framework, and it is difficult to compromise between them. In addition, the knowledge obtained by this information-theoretic SOM can be used to solve the shortage of unlabeled data, because the information maximization component is unsupervised and can process all input data with and without labels. The method was applied to the well-known image segmentation datasets. Experimental results showed that clear weights were produced and generalization performance was improved by using the information-theoretic SOM. In addition, the final results were stable, almost independent of the parameter values.

    Study question What is the prevalence of different types of potentially hazardous prescribing in general practice in the United Kingdom, and what is the variation between practices? Methods A cross sectional study included all adult patients potentially at risk of a prescribing or monitoring error defined by a combination of diagnoses and prescriptions in 526 general practices contributing to the Clinical Practice Research Datalink (CPRD) up to 1 April 2013. Primary outcomes were the prevalence of potentially hazardous prescriptions of anticoagulants, anti-platelets, NSAIDs, β blockers, glitazones, metformin, digoxin, antipsychotics, combined hormonal contraceptives, and oestrogens and monitoring by blood test less frequently than recommended for patients with repeated prescriptions of angiotensin converting enzyme inhibitors and loop diuretics, amiodarone, methotrexate, lithium, or warfarin. Study answer and limitations 49 927 of 949 552 patients at risk triggered at least one prescribing indicator (5.26%, 95% confidence interval 5.21% to 5.30%) and 21 501 of 182 721 (11.8%, 11.6% to 11.9%) triggered at least one monitoring indicator. The prevalence of different types of potentially hazardous prescribing ranged from almost zero to 10.2%, and for inadequate monitoring ranged from 10.4% to 41.9%. Older patients and those prescribed multiple repeat medications had significantly higher risks of triggering a prescribing indicator whereas younger patients with fewer repeat prescriptions had significantly higher risk of triggering a monitoring indicator. There was high variation between practices for some indicators. Though prescribing safety indicators describe prescribing patterns that can increase the risk of harm to the patient and should generally be avoided, there will always be exceptions where the indicator is clinically justified. Furthermore there is the possibility that some information is not captured by CPRD for some practices—for example, INR results in

    The Fukushima Daiichi nuclear power plant (FNP-1) accident, while as tragic as the tsunami, was a man-made disaster created by the ignorance of the effects of radiation and radioactive materials. Therefore, it is important that all specialists in radiation protection in medicine sympathize with the anxiety of the general public regarding the harmful effects of radiation and advise people accordingly. All questions and answers were collected related to inquiries from the general public that were posted to reliable websites, including those of the government and radiation-related organizations, from March 2011 to November 2012. The questions were summarized and classified by similarity of content. (1) The total number of questions is 372. The content was broadly classified into three categories: inquiries for radiation-related knowledge and about health effects and foods. The questions asked to obtain radiation-related knowledge were the most common, accounting for 38 %. Thirty-six percentage of the questions were related to health effects, and 26 % involved foods, whereas 18 % of the questions were related to children and pregnancy. (2) The change over time was investigated in 290 questions for which the time of inquiry was known. Directly after the earthquake, the questions were primarily from people seeking radiation-related knowledge. Later, questions related to health effects increased. The anxiety experienced by residents following the nuclear accident was caused primarily by insufficient knowledge related to radiation, concerns about health effects and uncertainties about food and water safety. The development of educational materials focusing on such content will be important for risk communication with the general public in countries with nuclear power plants. Physicians and medical physicist should possess the ability to respond to questions such as these and should continue with medical examinations and treatments in a safe and appropriate manner.

    The Relativistic Heavy Ion Collider (RHIC) under construction at Brookhaven National Laboratory, requires an extensive Access Control System to protect personnel from Radiation, Oxygen Deficiency and Electrical hazards. In addition, the complicated nature of operation of the Collider as part of a complex of other Accelerators necessitates the use of active electronic measurement circuitry to ensure compliance with established Operational Safety Limits. Solutions were devised which permit the use of modern computer and interconnections technology for Safety-Critical applications, while preserving and enhancing, tried and proven protection methods. In addition a set of Guidelines, regarding required performance for Accelerator Safety Systems and a Handbook of design criteria and rules were developed to assist future system designers and to provide a framework for internal review and regulation.

  10. The satiety signaling neuropeptide perisulfakinin inhibits the activity of central neurons promoting general activity

    Directory of Open Access Journals (Sweden)

    2007-12-01

    Full Text Available The metabolic state is one of the determinants of the general activity level. Satiety is related to resting or sleep whereas hunger correlates to wakefulness and activity. The counterpart to the mammalian satiety signal cholecystokinin (CCK in insects are the sulfakinins. The aim of this study was to resolve the mechanism by which the antifeedant activity of perisulfakinin (PSK in Periplaneta americana is mediated. We identified the sources of PSK which is used both as hormone and as paracrine messenger. PSK is found in the neurohemal organ of the brain and in nerve endings throughout the central nervous system. To correlate the distributions of PSK and its receptor (PSKR, we cloned the gene coding for PSKR and provide evidence for its expression within the nervous system. It occurs only in a few neurons, among them are the dorsal unpaired median (DUM neurons which release octopamine thereby regulating the general level of activity. Application of PSK to DUM neurons attenuated the spiking frequency (EC50=11pM due to reduction of a pacemaker Ca2+ current through cAMP-inhibited pTRPγ channels. PSK increased the intracellular cAMP level while decreasing the intracellular Ca2+ concentration in DUM neurons. Thus, the satiety signal conferred by PSK acts antagonistically to the hunger signal, provided by the adipokinetic hormone (AKH: PSK depresses the electrical activity of DUM neurons by inhibiting the pTRPγ channel that is activated by AKH under conditions of food shortage.

  11. Optimism about safety and group-serving interpretations of safety among pedestrians and cyclists in relation to road use in general and under low light conditions.

    Drivers are known to be optimistic about their risk of crash involvement, believing that they are less likely to be involved in a crash than other drivers. However, little comparative research has been conducted among other road users. In addition, optimism about crash risk is conceptualised as applying only to an individual's assessment of his or her personal risk of crash involvement. The possibility that the self-serving nature of optimism about safety might be generalised to the group-level as a cyclist or a pedestrian, i.e., becoming group-serving rather than self-serving, has been overlooked in relation to road safety. This study analysed a subset of data collected as part of a larger research project on the visibility of pedestrians, cyclists and road workers, focusing on a set of questionnaire items administered to 406 pedestrians, 838 cyclists and 622 drivers. The items related to safety in various scenarios involving drivers, pedestrians and cyclists, allowing predictions to be derived about group differences in agreement with items based on the assumption that the results would exhibit group-serving bias. Analysis of the responses indicated that specific hypotheses about group-serving interpretations of safety and responsibility were supported in 22 of the 26 comparisons. When the nine comparisons relevant to low lighting conditions were considered separately, seven were found to be supported. The findings of the research have implications for public education and for the likely acceptance of messages which are inconsistent with current assumptions and expectations of pedestrians and cyclists. They also suggest that research into group-serving interpretations of safety, even for temporary roles rather than enduring groups, could be fruitful. Further, there is an implication that gains in safety can be made by better educating road users about the limitations of their visibility and the ramifications of this for their own road safety, particularly in low

    High-precision machines typically suffer from small but annoying vibrations. As the most appropriate solution to a particular vibration problem is not always obvious, it may be convenient to cast the problem in a more general framework. This framework may then be used for frequency response analysis, which, together with close examination of the disturbance sources, leads to a solution in general structural terms, like ‘vibration isolation’, ‘stiffness enhancement’ or ‘damping augmentation’. ...

  14. Work Practice Simulation of Complex Human-Automation Systems in Safety Critical Situations: The Brahms Generalized berlingen Model

    2013-01-01

    The transition from the current air traffic system to the next generation air traffic system will require the introduction of new automated systems, including transferring some functions from air traffic controllers to on­-board automation. This report describes a new design verification and validation (V&V) methodology for assessing aviation safety. The approach involves a detailed computer simulation of work practices that includes people interacting with flight-critical systems. The research is part of an effort to develop new modeling and verification methodologies that can assess the safety of flight-critical systems, system configurations, and operational concepts. The 2002 Ueberlingen mid-air collision was chosen for analysis and modeling because one of the main causes of the accident was one crew's response to a conflict between the instructions of the air traffic controller and the instructions of TCAS, an automated Traffic Alert and Collision Avoidance System on-board warning system. It thus furnishes an example of the problem of authority versus autonomy. It provides a starting point for exploring authority/autonomy conflict in the larger system of organization, tools, and practices in which the participants' moment-by-moment actions take place. We have developed a general air traffic system model (not a specific simulation of Überlingen events), called the Brahms Generalized Ueberlingen Model (Brahms-GUeM). Brahms is a multi-agent simulation system that models people, tools, facilities/vehicles, and geography to simulate the current air transportation system as a collection of distributed, interactive subsystems (e.g., airports, air-traffic control towers and personnel, aircraft, automated flight systems and air-traffic tools, instruments, crew). Brahms-GUeM can be configured in different ways, called scenarios, such that anomalous events that contributed to the Überlingen accident can be modeled as functioning according to requirements or in an

    Occupational safety and health in disaster restoration activity following the Great Hanshin Earthquake (1995), Niigata Chuetsu Earthquake (2004), Niigata Chuetsu-oki Earthquake (2007) Great East Japan Earthquake (2011) were analyzed and characterized in order to raise awareness on the risks and hazards in such work. In this scenario, the predominant type of accident is a "fall" which increases mainly due to the fact that labourers are working to repair houses and buildings. On the other hand, landslides were prevalent in the Niigata Chuetsu Earthquake, resulting in more accidents occurring during geotechnical works rather than in buildings construction works. In the abnormal conditions that characterize recovery activities, when safety and health measures have a tendency to be neglected, it is important to reinstate adequate measures as soon as possible by carrying out the usial risk assessments.

    Report (FSAR) [3]. Depending on the availability of historical data derived from HEU TREAT operation, results calculated for the LEU core are compared to measurements obtained from HEU TREAT operation. While all analyses in this report are largely considered complete and have been reviewed for technical content, it is important to note that all topics will be revisited once the LEU design approaches its final stages of maturity. For most safety significant issues, it is expected that the analyses presented here will be bounding, but additional calculations will be performed as necessary to support safety analyses and safety documentation. It should also be noted that these analyses were completed as the LEU design evolved, and therefore utilized different LEU reference designs. Preliminary shielding, neutronic, and thermal hydraulic analyses have been completed and have generally demonstrated that the various LEU core designs will satisfy existing safety limits and standards also satisfied by the existing HEU core. These analyses include the assessment of the dose rate in the hodoscope room, near a loaded fuel transfer cask, above the fuel storage area, and near the HEPA filters. The potential change in the concentration of tramp uranium and change in neutron flux reaching instrumentation has also been assessed. Safety-significant thermal hydraulic items addressed in this report include thermally-induced mechanical distortion of the grid plate, and heating in the radial reflector.

Patients underwent X-ray examinations using iobitridol (Xenetix, Guerbet, Sulzbach, Germany) as IV contrast medium (mean volume 85.6 ml). 21.8% of all patients had at least one risk factor (e.g., renal impairment), 7.3% were at-risk patients with allergies or who had previously reacted to contrast medium. Antiallergic pretreatment before contrast medium administration was given in 1144 patients (0.7%). Adverse events were documented and the image quality was assessed. Results: A diagnosis was possible in 99.5% of all cases. The image quality was rated good or excellent in 92.2%. The adverse event rate (e.g., nausea, urticaria) observed was 0.6% in all patients, 1.6% in patients with allergies and 6.0% in patients with a previous reaction to contrast medium. Adverse events occurred more often in women than in men (p < 0.001). Pretreatment did not decrease the rate of adverse events. The rate of adverse events was not increased in higher doses of iobitridol, even if administered to high-risk patients. Conclusions: Iobitridol was shown to be a safe and well-tolerated contrast medium with a low incidence of adverse events in patients with and without risk factors resulting in a good or excellent image quality in most patients.

    The handling of laboratory, imaging and other test results in UK general practice is a high-volume organisational routine that is both complex and high risk. Previous research in this area has focused on errors and harm, but a complementary approach is to better understand how safety is achieved in everyday practice. This paper ethnographically examines the role of informal dimensions of test results handling routines in the achievement of safety in UK general practice and how these findings can best be developed for wider application by policymakers and practitioners. Non-participant observation was conducted of high-volume organisational routines across eight UK general practices with diverse organisational characteristics. Sixty-two semi-structured interviews were also conducted with the key practice staff alongside the analysis of relevant documents. While formal results handling routines were described similarly across the eight study practices, the everyday structure of how the routine should be enacted in practice was informally understood. Results handling safety took a range of local forms depending on how different aspects of safety were prioritised, with practices varying in terms of how they balanced thoroughness (i.e. ensuring the high-quality management of results by the most appropriate clinician) and efficiency (i.e. timely management of results) depending on a range of factors (e.g. practice history, team composition). Each approach adopted created its own potential risks, with demands for thoroughness reducing productivity and demands for efficiency reducing handling quality. Irrespective of the practice-level approach adopted, staff also regularly varied what they did for individual patients depending on the specific context (e.g. type of result, patient circumstances). General practices variably prioritised a legitimate range of results handling safety processes and outcomes, each with differing strengths and trade-offs. Future safety

The aim of the article is formation of economic safety management for international economic activity of machine-building enterprises.The results of the analysis. It is noted by authors that management of economic safety of FEA of machine-building enterprise has to include development of principles of management, structure of the organizational and economic mechanism of management, functions, administrative decisions which together lead implementation of basic task maintenance of sufficient level of FEA economic safety.In the research it is noted that combination of principles of economic safety, economic activity in a uniform complex allows to influence the formation of the purposes of the company and to make reasonable administrative decisions. Operation of organizational and economic mechanism of management as economic safety of FEA of machine-building enterprise needs to be considered as the activity directed on achievement of the objectives of management, and to determine by criterion of a condition of such mechanism level of economic safety of FEA. In the paper stages of management are offered by economic safety of FEA and divided into two main components which are the analysis of economic safety of FEA at the enterprise and measures for its increase and supports. Thus, analysis of economic safety of FEA provides collecting and data processing on main aspects of economic safety, its quantitative and qualitative analysis, and actions on increases and maintenance of economic safety of FEA provide a choice and justification of maximum permissible level of economic safety of FEA a choice of instruments of increase and

    The aims of the study were to recognise if there is any auditory sensory stimuli processing in cats under general anaesthesia, and to evaluate changes in respiratory rate (RR) and pupillary diameter (PD) in anaesthetised patients exposed to different music genres, while relating this to the depth of anaesthesia. A sample of 12 cats submitted for elective ovariohysterectomy was exposed to 2 min excerpts of three different music genres (classical [CM], pop [PM] and heavy metal [HM]) at three points during surgery (T1 = coeliotomy; T2 = ligature placement and transection of the ovarian pedicle; T3 = ligature placement and transection of the uterine body). A multiparametric medical monitor was used to measure the RR, and a digital calliper was used for PD measurement. Music was delivered through headphones, which fully covered the patient's ears. P values   music induces RR and PD variations modulated by the genre of music and is associated with autonomic nervous system activity. The use of music in the surgical theatre may contribute to allowing a reduced anaesthetic dose, minimising undesirable side effects and thus promoting patient safety. © ISFM and AAFP 2015.

    2008-04-01

    In 2004, we launched a new calculus-based, introductory physics sequence at Washington University. Designed as an alternative to our traditional lecture-based sequence, the primary objectives for this new course were to actively engage students in the learning process, to significantly strengthen students' conceptual reasoning skills, to help students develop higher level quantitative problem solving skills necessary for analyzing ``real world'' problems, and to integrate modern physics into the curriculum. This talk will describe our approach, using The Six Ideas That Shaped Physics text by Thomas Moore, to creating an active learning environment in large classes as well as share our perspective on key elements for success and challenges that we face in the large class environment.

    2015-12-01

    Full Text Available This study aimed to assess the acute toxicity and safety of flavonoid-rich extract from Maydis stigma (FMS in mice. The in vitro antioxidant activity of FMS was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH and 2,2′-azinobis-(3-ethyl-benzthiazoline-6-sulphonate (ABTS scavenging assays. Furthermore, the in vivo antioxidant of FMS against ethanol-induced oxidative damage in mice was determined by analysis of the serum total superoxide dismutase (T-SOD activity, malondialdehyde (MDA content, liver tissue glutathione (GSH content, and protein carbonyl (PC content in liver tissue. The oral administration of FMS at doses of 30 g/kg did not cause death in mice, and there were no significant biologically adverse effects in mice. These results indicated that the median lethal dose (LD50 is higher than this dose. The IC50 values of FMS for the DPPH and ABTS scavenging activity were 50.73 and 0.23 mg/mL, respectively. Meanwhile, FMS could significantly enhance T-SOD activity, reduce MDA content in the serum, increase GSH content, and decrease PC content in the liver tissue at the tested doses (25, 50, 100, 200 mg/kg·day. These results indicate that FMS can be generally regarded as safe and used potentially as a bioactive source of natural antioxidants.

    There are many concerns about radiation exposure in Korea after Fukushima Nuclear Plant Accident on 2011 in Japan. As some isotope materials are detected in Korea, people get worried about the radioactive material. In addition, the mass media create an air of anxiety that jump on the people’s fear instead of scientific approach. Therefore, for curbing this flow, health, medical institute from the world provide a variety of information about medical radiation safety and hold the campaign which can give people the image that medical radiation is safe. At this, the Korean Food and Drug Administration(KFDA) suggested that make the alliance of medical radiation safety and culture on August, 2011. Seven societies and institutions related medical radiation started to research and advertise the culture of medical radiation safety in Korea. In this report, mainly introduce the activities of the Korean Alliance for Radiation Safety and Culture in Medicine(KARSM) for spreading culture of medical radiation safety from 2011 to 2012.

    Full Text Available The article presents results of research of quality, safety and content of biologically active substances of food red beet roots of Bordo 237 variety, grown in the Krasnodar region in 2014. On the basis of the research carried out it was established, that there are carbohydrates, proteins, organic acids and mineral substances in the food red beet roots of Bordo 237 variety. Food red beet roots are a source of dietary fibers (pectin, protopectin, hemicelluloses and cellulose, possessing antitoxic, antioxidant, radiation protective, cholesterol-lowering and lipid correcting qualities, and also a source of vitamins C, B9 (folic acid and P-active substances, possessing antioxidant properties. Due to high content in food red beet of a complex of microelements – iron, zinc, manganese and copper, and a complex of macro elements – potassium and magnesium, it can be recommended for prophylaxis and treatment of hypertension, atherosclerosis and other diseases of heart and vascular system, and for prophylaxis of iron-deficiency anemia. Thus, the research of quality, safety and content of biologically active substances showed that food red beet roots of Bordo 237 variety are a high quality component ingredient for creation of food products of specialized and functional purpose

  8. Exposed to events that never happen: Generalized unsafety, the default stress response, and prolonged autonomic activity.

    Science.gov (United States)

    Brosschot, Jos F; Verkuil, Bart; Thayer, Julian F

    2017-03-01

    Based on neurobiological and evolutionary arguments, the generalized unsafety theory of stress (GUTS) hypothesizes that the stress response is a default response, and that chronic stress responses are caused by generalized unsafety (GU), independent of stressors or their cognitive representation. Three highly prevalent conditions are particularly vulnerable to becoming 'compromised' in terms of GU, and carry considerable health risks: Thus, GUTS critically revises and expands stress theory, by focusing on safety instead of threat, and by including risk factors that have hitherto not been attributed to stress.

  10. Active and Purely Dissipative Nambu Systems in General Thermostatistical Settings Described by Nonlinear Partial Differential Equations Involving Generalized Entropy Measures

    Directory of Open Access Journals (Sweden)

    T. D. Frank

    2016-12-01

    Full Text Available In physics, several attempts have been made to apply the concepts and tools of physics to the life sciences. In this context, a thermostatistic framework for active Nambu systems is proposed. The so-called free energy Fokker–Planck equation approach is used to describe stochastic aspects of active Nambu systems. Different thermostatistic settings are considered that are characterized by appropriately-defined entropy measures, such as the Boltzmann–Gibbs–Shannon entropy and the Tsallis entropy. In general, the free energy Fokker–Planck equations associated with these generalized entropy measures correspond to nonlinear partial differential equations. Irrespective of the entropy-related nonlinearities occurring in these nonlinear partial differential equations, it is shown that semi-analytical solutions for the stationary probability densities of the active Nambu systems can be obtained provided that the pumping mechanisms of the active systems assume the so-called canonical-dissipative form and depend explicitly only on Nambu invariants. Applications are presented both for purely-dissipative and for active systems illustrating that the proposed framework includes as a special case stochastic equilibrium systems.

    2016-10-10

    Purpose Interleukin-10 (IL-10) stimulates the expansion and cytotoxicity of tumor-infiltrating CD8+ T cells and inhibits inflammatory CD4+ T cells. Pegylation prolongs the serum concentration of IL-10 without changing the immunologic profile. This phase I study sought to determine the safety and antitumor activity of AM0010. Patients and Methods Patients with selected advanced solid tumors were treated with AM0010 in a dose-escalation study, which was followed by a renal cell cancer (RCC) dose-expansion cohort. AM0010 was self-administered subcutaneously at doses of 1 to 40 μg/kg once per day. Primary end points were safety and tolerability; clinical activity and immune activation were secondary end points. Results In the dose-escalation and -expansion cohorts, 33 and 18 patients, respectively, were treated with daily subcutaneous injection of AM0010. AM0010 was tolerated in a heavily pretreated patient population. Treatment-related adverse events (AEs) included anemia, fatigue, thrombocytopenia, fever, and injection site reactions. Grade 3 to 4 nonhematopoietic treatment-related AEs, including rash (n = 2) and transaminitis (n = 1), were observed in five of 33 patients. Grade 3 to 4 anemia or thrombocytopenia was observed in five patients. Most treatment-related AEs were transient or reversible. AM0010 led to systemic immune activation with elevated immune-stimulatory cytokines and reduced transforming growth factor beta in the serum. Partial responses were observed in one patient with uveal melanoma and four of 15 evaluable patients with RCC treated at 20 μg/kg (overall response rate, 27%). Prolonged stable disease of at least 4 months was observed in four patients, including one with colorectal cancer with disease stabilization for 20 months. Conclusion AM0010 has an acceptable toxicity profile with early evidence of antitumor activity, particularly in RCC. These data support the further evaluation of AM0010 both alone and in combination with other immune

  14. Active safety monitoring of new medical products using electronic healthcare data: Selecting alerting rules

    2012-01-01

    BACKGROUND Active medical-product-safety surveillance systems are being developed to monitor many products and outcomes simultaneously in routinely collected longitudinal electronic healthcare data. These systems will rely on algorithms to generate alerts about potential safety concerns. METHODS We compared the performance of five classes of algorithms in simulated data using a sequential matched-cohort framework, and applied the results to two electronic healthcare databases to replicate monitoring of cerivastatin-induced rhabdomyolysis. We generated 600,000 simulated scenarios with varying expected event frequency in the unexposed, alerting threshold, and outcome risk in the exposed, and compared the alerting algorithms in each scenario type using an event-based performance metric. RESULTS We observed substantial variation in algorithm performance across the groups of scenarios. Relative performance varied by the event frequency and by user-defined preferences for sensitivity versus specificity. Type I error-based statistical testing procedures achieved higher event-based performance than other approaches in scenarios with few events, whereas statistical process control and disproportionality measures performed relatively better with frequent events. In the empirical data, we observed 6 cases of rhabdomyolysis among 4,294 person-years of follow-up, with all events occurring among cerivastatin-treated patients. All selected algorithms generated alerts before the drug was withdrawn from the market. CONCLUSION For active medical-product-safety monitoring in a sequential matched cohort framework, no single algorithm performed best in all scenarios. Alerting algorithm selection should be tailored to particular features of a product-outcome pair, including the expected event frequencies and trade-offs between false-positive and false-negative alerting.

    In this paper,the drinking water biotic safety of particles and bacteria attached to fines in activated carbon process was investigated by actual treatment process and advanced treatment pilot trial with granular activated carbon.In the experiment,the particles were detected by IBR particle calculating instrument,the activated carbon fines were counted on the basis of the most probable number (MPN) with a microscope,the total number of bacteria was analyzed between the conventional agar culture medium and the one with R2A,and the bacteria attached to activated carbon fines was resolved by the homogenization technique.The experimental results showed that the average total number of particles was 205 CNT/mL in the activated carbon effluent during a filter cycle,of which the number of particles with sizes>2μm was 77 CNT/mL more than the present particle control criterion of the American drinking water product standard (50 CNT/mL).The backwash of low density and long duration lowered particle number in the effluent.The MPN of activated carbon frees in the effluent was between 400 and 600 CNT/L,which accounted for less than 5‰ of the total particles from activated carbon filtration for a poor relative level (R2= 0.34).The microorganisms in activated carbon effluent consisted mostly of heterotrophic bacillus and the total bacteria number was five times as high as that of the inflow,i.e.the effluent from sand filter.The actual bacteria number may be truly indicated by the detection technique with R2A culture medium compared with the traditional agar cultivation.The inactivation efficiency of bacteria attached to activated carbon fines was less than 40% under 1.1 mg/L of chlorine contacting for 40 min.Results showed that the particles and bacteria attached to activated carbon fines may influence drinking water biotic safety,and that the effective control measures need to be further investigated.

    Full Text Available The antibiotic susceptibility and antimicrobial activity, as food safety parameters important for application of autochthonous lactic acid bacteria (LAB, that previously satisfied technological criteria for functional starter cultures in fresh cheese production were examined. Soluble whole cell protein patterns of autochthonous LAB strains from fresh cheese, obtained by SDS-PAGE, revealed the presence of two predominant strains, which were identified as Lactobacillus fermentum A8 and Enterococcus faecium A7. These strains were not resistant and shown susceptibility to antibiotics: ampicillin, bacitracin, penicillin G, azithromycin, chloramphenicol, clarithromycin, clindamycin, spiramycin, tetracycline, streptomycin, neomycin, gentamicin, erythromycin, rifampicin and novobiocin. Lb. fermentum A8 strain displayed phenotypic resistance to vancomycin, but this resistance is intrinsic, not transferable and it is acceptable from the safety aspect. The capacity of Lb. fermentum A8 and Ec. faecium A7 to inhibit growth of test-microorganisms Listeria monocytogenes ATCC 11911, Escherichia coli 3014, Salmonella enterica serovar Typhimurium FP1 and Staphylococcus aureus 3048, was also analysed. According to obtained results, Lb. fermentum A8 and Ec. faecium A7 are safe from the aspect of spreading antibiotic resistance and could be useful as bioprotective cultures that inhibit common bacterial food contaminants, including L. monocytogenes.

    Most women experience significant changes in their general health status during menopause, which negatively affects their quality of life. Physical activity has also been shown to enhance quality of life. However, little is known about the effect of physical activity on women's health during the menopausal transition. This study aimed to determine the relationship between physical activity and general health among menopausal women in Ahvaz, Iran. This cross sectional study was carried out on 600 menopausal women using cluster random sampling during 2013-2014. Data collection tools were three questionnaires; women's demographic characteristics, the Goldenberg's questionnaire, and International physical activity questionnaire (IPAQ). Data were analyzed using descriptive and inferential statistics through SPSS version 19. The statistical tests were performed at the 95% confidence interval. There was a significant relationship between the total score of physical activity and physical health, social functioning, anxiety and depression (prelationship was found between subscales related to physical activity and general health (p>0.05). Physical activity is effective in improving general health in menopausal women. Proper training and effective interventions for regular physical activity can be important steps to promote the general health of menopausal women.

  13. Safety-Related Contractor Activities at Nuclear Power Plants. New Challenges for Regulatory Oversight

    Energy Technology Data Exchange (ETDEWEB)

    2005-09-15

    The use of contractors has been an integral and important part of the design, construction, operation, and maintenance of nuclear power plants. To ensure the safe and efficient completion of contracted tasks, each nuclear plant licensee has developed and refined formal contract management processes to meet their specific needs and plant requirements. Although these contract management processes have proven to be effective tools for the procurement of support and components tailored to the needs of nuclear power plants, contractor-related incidents and accidents have revealed some serious weaknesses with the implementation of these processes. Identifying and addressing implementation problems are becoming more complicated due to organizational and personnel changes affecting the nuclear power industry. The ability of regulators and licensees to effectively monitor and manage the safety-related performance of contractors will likely be affected by forthcoming organization and personnel changes due to: the aging of the workforce; the decline of the nuclear industry; and the deregulation of nuclear power. The objective of this report is to provide a review of current and potential future challenges facing safety-related contractor activities at nuclear power plants. The purpose is to assist SKI in establishing a strategy for the proactive oversight of contractor safety-related activities at Swedish nuclear power plants and facilities. The nature and role of contractors at nuclear plants is briefly reviewed in the first section of the report. The second section describes the essential elements of the contract management process. Although organizations have had decades of experience with the a contract management process, there remain a number of common implantation weaknesses that have lead to serious contractor-related incidents and accidents. These implementation weaknesses are summarized in the third section. The fourth section of the report highlights the

    Fermented Virgin Coconut Oil (FVCO) is widely used in the Southeast Asia as food and traditional medicine. The objective of the present study is the evaluation of chronic safety of the commercialized FVCO of Malaysia and other Southeast Asian countries. A single dose of 5000 mg/kg of FVCO was administered orally in rats (each group, n = 5) for the acute toxicity study and 175, 550 and 2000 mg/kg for sub-chronic and chronic studies (each group, n = 10), respectively. The behavior, mortality, and body weight of the rats were assessed to determine the toxic effects of FVCO. The haematology, biochemistry and histopathology of the treated rats were evaluated. The treated rats were safe with the dose of 5000 mg/kg in acute, sub-chronic and chronic indication. Abnormal clinical signs and morphology (gross necroscopy), changes of organ weight, anomalous haematology and biochemistry indexes were not found in comparison with the control (p > 0.05). In general, food and water intake were higher in the treated rats related to control. It was concluded that the presence of the antioxidant active compounds of FVCO might be the reason of safety. The structure activity relationship (SAR) provides a comprehensive mechanism to determine the safety that is the presence of the electron donating phenolic groups, carbonyl groups, and carboxylic acid in the ortho and meta position of the aromatic rings. The SAR showed the antioxidant properties of myristic acid and lauric acid determined by GC-MS analysis. This result suggests the safety of FVCO for chronic use, nutritional activity that FVCO formulation complies the requirements of regulatory agencies.

  20. Activity of the anterior cingulate cortex and ventral hippocampus underlie increases in contextual fear generalization.

    Memories for context become less specific with time resulting in animals generalizing fear from training contexts to novel contexts. Though much attention has been given to the neural structures that underlie the long-term consolidation of a context fear memory, very little is known about the mechanisms responsible for the increase in fear generalization that occurs as the memory ages. Here, we examine the neural pattern of activation underlying the expression of a generalized context fear memory in male C57BL/6J mice. Animals were context fear conditioned and tested for fear in either the training context or a novel context at recent and remote time points. Animals were sacrificed and fluorescent in situ hybridization was performed to assay neural activation. Our results demonstrate activity of the prelimbic, infralimbic, and anterior cingulate (ACC) cortices as well as the ventral hippocampus (vHPC) underlie expression of a generalized fear memory. To verify the involvement of the ACC and vHPC in the expression of a generalized fear memory, animals were context fear conditioned and infused with 4% lidocaine into the ACC, dHPC, or vHPC prior to retrieval to temporarily inactivate these structures. The results demonstrate that activity of the ACC and vHPC is required for the expression of a generalized fear memory, as inactivation of these regions returned the memory to a contextually precise form. Current theories of time-dependent generalization of contextual memories do not predict involvement of the vHPC. Our data suggest a novel role of this region in generalized memory, which should be incorporated into current theories of time-dependent memory generalization. We also show that the dorsal hippocampus plays a prolonged role in contextually precise memories. Our findings suggest a possible interaction between the ACC and vHPC controls the expression of fear generalization.

    2011-03-01

    Full Text Available Active chassis systems like braking, steering, suspension and propulsion systems are increasingly entering the market. In addition to their basic functions, these systems may be used for functions of integrated vehicle dynamics control. An experimental platform which aims to study the integration control of steering and braking is designed due to the research requirement of vehicle active safety control strategy in this paper. A test vehicle which is equipped with the systems of steer-by-wire and brake-bywire is provided and the Autobox, combined with Matlab/simulink and MSCCarsim, is used to fulfill the RCP (Rapid Control Prototyping and HIL (Hardware-in-loop. The seven-freedom vehicle model is constructed first and the approach of vehicle parameters estimation based on the Extended Kalman Filter (EKF is proposed. Testing the vehicle state through the sensor has its own disadvantage that the cost is high and easily affected by environment outside. To find a actual method of receiving the vehicle state using the ready-made sensors in vehicle, the researchers put forward various estimation method, of which have advantages and disadvantages. Based on the above, this paper applies the EKF to estimate the vehicle state, making the actual estimation come true. The primary control methods and controller designment is carried out to prove the validation of the platform.

    Introduction Most women experience significant changes in their general health status during menopause, which negatively affects their quality of life. Physical activity has also been shown to enhance quality of life. However, little is known about the effect of physical activity on women’s health during the menopausal transition. This study aimed to determine the relationship between physical activity and general health among menopausal women in Ahvaz, Iran. Methods This cross sectional study was carried out on 600 menopausal women using cluster random sampling during 2013–2014. Data collection tools were three questionnaires; women’s demographic characteristics, the Goldenberg’s questionnaire, and International physical activity questionnaire (IPAQ). Data were analyzed using descriptive and inferential statistics through SPSS version 19. The statistical tests were performed at the 95% confidence interval. Results There was a significant relationship between the total score of physical activity and physical health, social functioning, anxiety and depression (p0.05). Conclusion Physical activity is effective in improving general health in menopausal women. Proper training and effective interventions for regular physical activity can be important steps to promote the general health of menopausal women. PMID:28243418

    Acetyl aspartic acid (A-A-A) was proposed as a new novel active ingredient for use in cosmetics. The safety of A-A-A was assessed by following an in-house-developed 'New Ingredient Testing Strategy', which was designed in accordance with the Scientific Committee on Consumer Safety (SCCS) notes of guidance and the requirements of Annex I of the EU Cosmetics Regulation. The aim of the project was to determine whether A-A-A was safe for use in cosmetics and to determine a maximum permitted safe level in the formulations. A literature review was conducted, consulting over 40 different information sources. This highlighted a number of gaps which required testing data. A-A-A was tested for phototoxicity according to OECD test guideline 432, skin irritation according to OECD test guideline 439 and eye irritation according to OECD test guideline 437. Dermal absorption of A-A-A was measured according to OECD test guideline 428 and was used to calculate the margin of safety (MoS). Finally, A-A-A was tested in a human repeat insult patch test (HRIPT) and a 14-day in-use tolerance study. A-A-A was non-phototoxic and was non-irritating to skin and eyes in in vitro testing. Dermal absorption was calculated to be 5%. The MoS for A-A-A was 351, at a level of 5%, for all cosmetic product types, indicating no systemic safety toxicity concern. A-A-A at 5% under occlusive patch on a panel of 50 adult volunteers induced no skin irritation or allergic reaction in the HRIPT study. Finally, repeated application of A-A-A to the periocular area, twice per day for 14 days, in 21 female volunteers, demonstrated that 1% A-A-A was well tolerated following dermatological and ophthalmological assessment in a cosmetic formulation. A-A-A was assessed as safe by the cosmetic safety assessor for use in cosmetics at a level of 5% in all cosmetic product types, in line with the requirements of the EU Cosmetics Regulation and in accordance with the SCCS notes of guidance. © 2015 Society of Cosmetic

    The present article summarizes Metabolites in Safety Testing (MIST) studies on a glucokinase activator, N,N-dimethyl-5-((2-methyl-6-((5-methylpyrazin-2-yl)carbamoyl)benzofuran-4-yl)oxy)pyrimidine-2-carboxamide (PF-04937319), which is under development for the treatment of type 2 diametes mellitus. Metabolic profiling in rat, dog, and human hepatocytes revealed that PF-04937319 is metabolized via oxidative (major) and hydrolytic pathways (minor). N-Demethylation to metabolite M1 [N-methyl-5-((2-methyl-6-((5-methylpyrazin-2-yl)carbamoyl)benzofuran-4-yl)oxy)pyrimidine-2-carboxamide] was the major metabolic fate of PF-04937319 in human (but not rat or dog) hepatocytes, and was catalyzed by CYP3A and CYP2C isoforms. Qualitative examination of circulating metabolites in humans at the 100- and 300-mg doses from a 14-day multiple dose study revealed unchanged parent drug and M1 as principal components. Because M1 accounted for 65% of the drug-related material at steady state, an authentic standard was synthesized and used for comparison of steady-state exposures in humans and the 3-month safety studies in rats and dogs at the no-observed-adverse-effect level. Although circulating levels of M1 were very low in beagle dogs and female rats, adequate coverage was obtained in terms of total maximal plasma concentration (∼7.7× and 1.8×) and area under the plasma concentration-time curve (AUC; 3.6× and 0.8× AUC) relative to the 100- and 300-mg doses, respectively, in male rats. Examination of primary pharmacology revealed M1 was less potent as a glucokinase activator than the parent drug (compound PF-04937319: EC50 = 0.17 μM; M1: EC50 = 4.69 μM). Furthermore, M1 did not inhibit major human P450 enzymes (IC50 > 30 μM), and was negative in the Salmonella Ames assay, with minimal off-target pharmacology, based on CEREP broad ligand profiling. Insights gained from this analysis should lead to a more efficient and focused development plan for fulfilling MIST requirements with

    2000-02-01

    This is the tenth Annual Report to the Congress describing Department of Energy activities in response to formal recommendations and other interactions with the Defense Nuclear Facilities Safety Board (Board). The Board, an independent executive-branch agency established in 1988, provides advice and recommendations to the Secretary of Energy regarding public health and safety issues at the Department's defense nuclear facilities. The Board also reviews and evaluates the content and implementation of health and safety standards, as well as other requirements, relating to the design, construction, operation, and decommissioning of the Department's defense nuclear facilities. During 1999, Departmental activities resulted in the closure of nine Board recommendations. In addition, the Department has completed all implementation plan milestones associated with three Board recommendations. One new Board recommendation was received and accepted by the Department in 1999, and a new implementation plan is being developed to address this recommendation. The Department has also made significant progress with a number of broad-based initiatives to improve safety. These include expanded implementation of integrated safety management at field sites, opening of a repository for long-term storage of transuranic wastes, and continued progress on stabilizing excess nuclear materials to achieve significant risk reduction.

    Although probiotic-containing nutrient formulas for infants and toddlers have become very popular, some adverse effects related to translocation of probiotic strains have been reported. We assessed the safety of probiotic bifidobacteria that have been used in clinical investigations and proven to have beneficial effects, by analyzing mucin degradation activity and translocation ability. Mucin degradation activities of three probiotic bifidobacteria strains; Bifidobacterium longum BB536, Bifidobacterium breve M-16V and Bifidobacterium infantis M-63, were evaluated by three in vitro tests comprising growth in liquid medium, SDS-PAGE analysis of degraded mucin residues, and degradation assay in Petri dish. All test strains and control type strains failed to grow in the liquid medium containing mucin as the only carbon source, although good growth was obtained from fecal sample. In the SDS-PAGE analyses of mucin residues and observation of mucinolytic zone in agar plate, the three test strains also showed no mucin degradation activity as the type strains, although fecal sample yielded positive results. In another study, a high dose of B. longum BB536 was administered orally to conventional mice to examine the translocation ability. No translocation into blood, liver, spleen, kidney and mesenteric lymph nodes was observed and no disturbance of epithelial cells and mucosal layer in the ileum, cecum and colon was detected, indicating that the test strain had no translocation ability and induced no damage to intestinal surface. These results resolve the concern about bacterial translocation when using bifidobacteria strains as probiotics, which have been tested in various clinical trials, supporting the continuous use of these probiotic strains without anxiety.

    Global spread of counterfeit medicines is an imminent threat for the patients' safety. Although major targets of counterfeits are still erectile dysfunction (ED) drugs in the industrialized countries, including Japan, anti-cancer agents and some medicines for metabolic syndromes are also being counterfeited and circulated to the market mainly through the Internet. Due to the global expansion of the business, pharmaceutical companies based in Japan are suffering from the damage of counterfeits, illegal sales including diversion, and thefts, which have never been experienced in the conventional domestic market. We, pharmaceutical companies, must be responsible for the prevention of the prevalence because our mission is to deliver effective and safe medicine to patients. For this end, we are taking necessary actions including, 1. Forestalling counterfeit, falsification and illicit trade: Measures to prevent counterfeiting are taken by introducing anti-counterfeit technologies to the packaging and tablets on a risk basis. It is also important to establish supply chain security on a global scale. 2. Finding out counterfeits and cooperating crackdown: We are conducting market and internet surveillances when high risk products are sold in high risk markets. The outcome of the criminal investigation is reported to authorities and police if necessary. 3. Conducting educational campaign to medical staff or patients: For example, four companies which manufacture and sell ED drug in Japan are collaboratively continuing activities to raise the awareness of the danger of Internet purchase. To deliver effective and safe medicines stably and globally, pharmaceutical companies extend comprehensive measures against counterfeit and illicit trading.

  1. Study of Active Ingredients in Black Soybean Sprouts and Their Safety in Cosmetic Use

    2012-10-01

    Full Text Available Active ingredients in different lengths of black soybean sprouts were extracted with water. Concentrations of the main proteins and polysaccharides were determined by the Forint phenol assay and phenol-sulfuric acid assay, respectively. Anti-oxidizing capacities of the extracts were measured in vitro using the DPPH scavenging test and whitening capacity was measured in vitro using the tyrosinase inhibition test. The effects of the bean sprout extracts on human skin fibroblasts damnified by H2O2 were studied using an MTT colorimetric assay. The safety of the extracts was determined using the red blood cell (RBC test, chick chorioallantoic membrane (CAM assay and human patch test. Results show that DPPH radical scavenging rates at different shoot lengths were all greater than 95%, while the tyrosinase inhibition capacity of the extracts reached 98%. Hemolysis rate in all extracts were lower than 10%, below the 20% regulatory limit for the RBC test. No signs of allergic reactions were observed in the human patch tests. The optimum extract was obtained from bean sprouts grown to 0.5 cm. Extracts of black bean sprouts are safe and can be used as additives in anti-aging and whitening cosmetic products.

  2. Issues and challenges for pedestrian active safety systems based on real world accidents.

    2015-09-01

    The purpose of this study was to analyze real crashes involving pedestrians in order to evaluate the potential effectiveness of autonomous emergency braking systems (AEB) in pedestrian protection. A sample of 100 real accident cases were reconstructed providing a comprehensive set of data describing the interaction between the vehicle, the environment and the pedestrian all along the scenario of the accident. A generic AEB system based on a camera sensor for pedestrian detection was modeled in order to identify the functionality of its different attributes in the timeline of each crash scenario. These attributes were assessed to determine their impact on pedestrian safety. The influence of the detection and the activation of the AEB system were explored by varying the field of view (FOV) of the sensor and the level of deceleration. A FOV of 35° was estimated to be required to detect and react to the majority of crash scenarios. For the reaction of a system (from hazard detection to triggering the brakes), between 0.5 and 1s appears necessary.

    Rossi, Ernest; Erickson-Klein, Roxanna; Rossi, Kathryn

    2008-10-01

    This paper presents a highly edited version of a videotape made in 1980 by Marion Moore, M.D., showing Milton H. Erickson and Moore demonstrating novel, activity-dependent approaches to hand-levitation and therapeutic hypnosis on their subject, Ernest Rossi. Erickson's naturalistic and utilization approach is described in his very direct and surprising induction in a trance challenged patient. These novel, and surprising inductions are examples of how Erickson was prescient in developing activity-dependent approaches to therapeutic hypnosis and psychotherapy several generations before modern neuroscience documented the activity-dependent molecular-genomic mechanisms of memory, learning, and behavior change. Erickson describes a case where he utilized what he called, "The General Waking Trance" when he "dared" not use an obvious hypnotic induction. It is proposed that the states of intense mental absorption and response attentiveness that are facilitated by the general waking trance are functionally related to the three conditions neuroscientists have identified as novelty, enrichment, and exercise (both mental and physical), which can turn on activity-dependent gene expression and activity-dependent brain plasticity, that are the molecular-genomic and neural basis ofmemory, learning, consciousness, and behavior change. We recommend that the next step in investigating the efficacy of therapeutic hypnosis will be in partnering with neuroscientists to explore the possibilities and limitations of utilizing the activity-dependent approaches to hypnotic induction and the general waking trance in facilitating activity-dependent gene expression and brain plasticity.

    This study examines nurse-physician teamwork and collaboration, a critical component in the delivery of safe patient care, on general medical units. To that end, we assess shared mental models and mutual trust, 2 coordinating mechanisms that help facilitate teamwork, among nurses and physicians working on general medical units. Data were collected from 37 nurses and 42 physicians at an urban teaching medical center in the Northeastern United States. Shared mental model questionnaire items were iteratively developed with experts' input to ensure content validity. Mutual trust items were adapted from an existing scale; items were reliable. Data were analyzed using χ and independent 2-tailed t tests. Physicians and nurses reported significant differences in their perceptions of the professional responsible for a variety of roles (e.g., advocating for the patient [P = 0.0007], identifying a near miss/error [P = 0.003]). Medication reconciliation is only role for which nurses perceive less responsibility than physicians perceive nurses have. Regarding mutual trust, both groups reported significantly more trust within their own professions; both groups reported similar levels of trust in physicians, with physicians reporting significantly less trust in their nursing colleagues than nurses perceive (P collaboration, more work is needed. To that end, we propose increasing knowledge about their respective roles, providing opportunities for nurse and physician collaboration through rounding or committee work and enhancing the preparedness and professionalism of interactions.

    This report presents a simplified method to assess the health and safety risk of Environmental Management activities of the US Department of Energy (DOE). The method applies to all types of Environmental Management activities including waste management, environmental restoration, and decontamination and decommissioning. The method is particularly useful for planning or tradeoff studies involving multiple conceptual options because it combines rapid evaluation with a quantitative approach. The method is also potentially applicable to risk assessments of activities other than DOE Environmental Management activities if rapid quantitative results are desired.

    Seven school districts or comprehensive high schools were enrolled in online OSHA 10-hour General Industry or Construction health and safety training via CareerSafe to determine the feasibility of online training for students, given limited resources for in-person trainings. A two-campus school district was analyzed comparing OSHA 10 for General Industry across in-person, supervisor-level teachers as authorized trainers, and online course formats. The online training courses were completed by 86 of 91 students, while another 53 of 57 students completed in-person training. Both groups completed identical OSHA-approved quizzes for "Introduction to OSHA," the initial 2-h module consistently provided in OSHA 10 courses across topics and formats. Results indicated teacher supervision was critical, and girls had higher online course completion rates, overall quiz scores, and never failed. Though both cohorts passed, in-person had significantly higher scores than online; both struggled with two questions. Online OSHA 10 for General Industry can be an efficient learning tool for students when limited resources prevent widespread availability of in-person courses.

    More recently, companies that have obtained permission to use radioactive materials or radiation device and registered radiation workers have increased by 10% and 4% respectively. The increased use of radiation could have an effect on radiation safety control. However, there is not nearly enough manpower and budget compared to the number of workers and facilities. This paper will suggest a counteroffer thought analyzing pending issues. The results of this paper indicate that there are 47 and 31.3 workers per radiation protection officer in educational and research institutes, respectively. There are 20.1 persons per RPO in hospitals, even though there are 2 RPOs appointed. Those with a special license as a radioisotope handler were ruled out as possible managers because medical doctors who have a special license for radioisotope handling normally have no experience with radiation safety. The number of staff members and budget have been insufficient for safety control at most educational and research institutes. It is necessary to build an optimized safety control system for effective Radiation Safety Control. This will reduce the risk factor of safety, and a few RPOs can be supplied for efficiency and convenience.

  18. Maintenance: organizational modes, activities and health and safety. Use of a French national survey and in-situ analyses.

    Grusenmeyer, Corinne

    2014-12-01

    Maintenance activities are identified as critical both to operator safety and to systems safety and reliability. However, it is still difficult to identify maintenance workers in French occupational accident and disease statistics. Moreover, few analyses of these activities and of organizational changes in this field have been conducted. This paper presents two different approaches to this same issue. Analyses were aimed firstly at identifying the occupational exposures of these operators and at comparing them with occupational exposures of production staff and, secondly at developing understanding of normal real maintenance activities, i.e. maintenance activities that are normally actually carried out, while taking into account the socio-technical system and maintenance organization within which they lie. The use of the French SUMER 2003 survey shows that occupational exposures of maintenance staff to various constraints are more frequent than occupational exposures of their production colleagues. However, maintenance staff appear to have greater independence. Analyses were also conducted in a subcontracting urban public transport company, who outsources some maintenance work. Those analyses highlight a complex network of companies involved in maintenance activities, a substantial number of work interruptions and a significant fragmentation of the internal technicians' activities that can be cognitively costly, reduce anticipation possibilities and lead to incidents or accidents. Above all they underline internal technicians' contributions to the completion of outsourced interventions and interdependent relationships between the activities of the internal and the external technicians. Outsourcing maintenance interventions thus raises the question of risks associated with the interdependence of actual work activities undertaken by the different types of staff, since they contribute to the same maintenance intervention. This study therefore pinpoints the need to

  19. A general approach toward enhancement of pseudocapacitive performance of conducting polymers by redox-active electrolytes

    KAUST Repository

    Chen, Wei

    2014-12-01

    A general approach is demonstrated where the pseudocapacitive performance of different conducting polymers is enhanced in redox-active electrolytes. The concept is demonstrated using several electroactive conducting polymers, including polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene). As compared to conventional electrolytes, the redox-active electrolytes, prepared by simply adding a redox mediator to the conventional electrolyte, can significantly improve the energy storage capacity of pseudocapacitors with different conducting polymers. The results show that the specific capacitance of conducting polymer based pseudocapacitors can be increased by a factor of two by utilization of the redox-active electrolytes. In fact, this approach gives some of the highest reported specific capacitance values for electroactive conducting polymers. Moreover, our findings present a general and effective approach for the enhancement of energy storage performance of pseudocapacitors using a variety of polymeric electrode materials. © 2014 Elsevier B.V.

    1996-04-01

    In an effort to more effectively integrate the experimental nature of chemistry into our students' experiences, we are developing and implementing discovery-based activities into both the laboratory and lecture components of general chemistry. Below we describe and provide an example of a "take-home challenge" intended to supplement the lecture component of the course. These take-home challenges involve the student in chemistry exploration outside of class and extend the context of content and experimentation into a nontraditional laboratory environment. Over 25 take-home challenges have been developed to date. Preliminary evaluation of the impact of the take-home challenges shows that students reporting themselves as receiving a B or C grade in the course find the challenges very useful in helping them gain a conceptual understanding of the phenomena addressed. Students earning an A grade report little or no impact on their learning. Prepared as one-page handouts, each take-home challenge begins with a scene-setting introduction followed by pertinent background information, a list of materials to be collected, and any appropriate safety precautions. The exploration component of the activity integrates leading questions with the procedural instructions to help guide the students through the discovery process and challenge them to stretch their understanding of the chemistry. After completing a take-home challenge activity, students submit written reports containing responses to the questions posed, observations of data collected, and their responses to the challenge. The accompanying sample take-home challenge activity is provided as a novel adaptation of the belch phenomenon that challenges students to experiment in order to explain the factors that account for the observed behavior. Persons interested in field testing the take-home challenges with their classes should contact the authors. Belch Bottle Challenge: What factors are responsible for the behavior of a

  1. Calpain Activity Is Generally Elevated during Transformation but Has Oncogene-Specific Biological Functions

    Directory of Open Access Journals (Sweden)

    N.O. Carragher

    2004-01-01

    Full Text Available Several oncogene and tumor-suppressor gene products are known substrates for the calpain family of cysteine proteases, and calpain is required for transformation by v-src and tumor invasion. Thus, we have now addressed whether calpain is generally associated with transformation and how calpain contributes to oncogene function. Our results demonstrate that calpain activity is enhanced upon transformation induced by the v-Src, v-Jun, v-Myc, k-Ras, and v-Fos oncoproteins. Furthermore, elevated calpain activity commonly promotes focal adhesion remodelling, disruption of actin cytoskeleton, morphological transformation, and cell migration, although proteolysis of target substrates (such as focal adhesion kinase, talin, and spectrin is differently specified by individual oncoproteins. Interestingly, v-Fos differs from other common oncoproteins in not requiring calpain activity for actin/adhesion remodelling or migration of v-Fos transformed cells. However, anchorage-independent growth of all transformed cells is sensitive to calpain inhibition. In addition, elevated calpain activity contributes to oncogene-induced apoptosis associated with transformation by v-Myc. Taken together, these studies demonstrate that calpain activity is necessary for full cellular transformation induced by common oncoproteins, but has distinct roles in oncogenic events induced by individual transforming proteins. Thus, targeting calpain activity may represent a useful general strategy for interfering with activated protooncogenes in cancer cells.

    Full Text Available The purpose of the study was to determine the effects of static and dynamic stretching protocols within general and activity specific warm-ups. Nine male and ten female subjects were tested under four warm-up conditions including a 1 general aerobic warm-up with static stretching, 2 general aerobic warm-up with dynamic stretching, 3 general and specific warm-up with static stretching and 4 general and specific warm-up with dynamic stretching. Following all conditions, subjects were tested for movement time (kicking movement of leg over 0.5 m distance, countermovement jump height, sit and reach flexibility and 6 repetitions of 20 metre sprints. Results indicated that when a sport specific warm-up was included, there was an 0.94% improvement (p = 0.0013 in 20 meter sprint time with both the dynamic and static stretch groups. No such difference in sprint performance between dynamic and static stretch groups existed in the absence of the sport specific warm-up. The static stretch condition increased sit and reach range of motion (ROM by 2.8% more (p = 0.0083 than the dynamic condition. These results would support the use of static stretching within an activity specific warm-up to ensure maximal ROM along with an enhancement in sprint performance

    To examine relationships between parenting styles and practices and child moderate-to-vigorous physical activity (MVPA) and screen time. Participants were children (6.9 ± 1.8 years) with a body mass index in the 70-95th percentile and their parents (421 dyads). Parent-completed questionnaires assessed parental support for child physical activity (PA), parenting styles and child screen time. Children wore accelerometers to assess MVPA. Parenting style did not predict MVPA, but support for PA did (positive association). The association between support and MVPA, moreover, varied as a function of permissive parenting. For parents high in permissiveness, the association was positive (greater support was related to greater MVPA and therefore protective). For parents low in permissiveness, the association was neutral; support did not matter. Authoritarian and permissive parenting styles were both associated with greater screen time. Parenting practices and styles should be considered jointly, offering implications for tailored interventions. © The Author 2014.

    Current regulation is a critical issue for the stable operation of three-phase active power filters (APF). The challenge of the current controller lies in how to track the high slew rate reference with zero steady-state error in a fast and accurate way. Conventionally, multiple paralleled second-order...... generalized integrators (SOGIs) are utilized to achieve those objectives. However, it will increase the computational burden due to calculation of the multiple paralleled SOGIs. To overcome this issue, phase compensated reduced order generalized integrator (ROGI) is proposed in this paper. Compared...

  9. On the Procedures for the Demonstration of the RF Safety of Active and Passive Implants in MRI Environments

    2016-01-01

    As a diagnostic method, magnetic resonance imaging (MRI) is not allowed to be used in patients with medical implants, including both active implants (such as cardiac deifbrillators or deep brain stimulators) and passive implants (such as orthopedics implants and support). MRI imaging scanning can produce magnetic ifelds, which will produce concentrated electromagnetic induction on metal edges of the implants, such as electrodes. The magnetic ifeld can also signiifcantly increase the temperature of surrounding tissues. Besides, the currents and voltage produced by active implants when exposed to MRI scanning can lead to damage and malfunction of pulse generators. Therefore, patients with medical implants cannot receive MRI as a diagnostic method. This safety protocol prevents a large group of patients from receiving MRI diagnosis. This leads to the conclusion that the safety evaluation of implants under MRI environment requires the combination of accurate data analysis and experimental techniques so as to establish the standard testing program.

  10. The compatibility of general managers' activities and intentions in managing change in the NHS.

    Science.gov (United States)

    Spurgeon, P; Barwell, F

    1990-03-01

    As Hales (1986) has observed, the problem of much of the managerial research to date has been the reluctance to ask why managers behave in the way they do. The behaviour of general managers in tackling organisational change in the NHS needs to be viewed not only with respect to what is done but also with respect to how personal and organisational objectives are construed. In other words, the implementation of organisational change ultimately rests on how general managers perceive the nature of this change and their role in structuring their own personal and organisational objectives into appropriate activities. Examining the compatibility of managerial activities and the underlying values and intentions which support them is of critical importance in any cognitively-based approach. These intentions provide an important link between perceptions (i.e. how the organisation is construed) and behaviour (i.e. what activities managers choose to perform). Understanding the conceptual frameworks which underpin managerial activities could have profound implications for assessing the performance of general managers.

  11. The generalized Hill model: A kinematic approach towards active muscle contraction

    Science.gov (United States)

    Göktepe, Serdar; Menzel, Andreas; Kuhl, Ellen

    2014-12-01

    Excitation-contraction coupling is the physiological process of converting an electrical stimulus into a mechanical response. In muscle, the electrical stimulus is an action potential and the mechanical response is active contraction. The classical Hill model characterizes muscle contraction though one contractile element, activated by electrical excitation, and two non-linear springs, one in series and one in parallel. This rheology translates into an additive decomposition of the total stress into a passive and an active part. Here we supplement this additive decomposition of the stress by a multiplicative decomposition of the deformation gradient into a passive and an active part. We generalize the one-dimensional Hill model to the three-dimensional setting and constitutively define the passive stress as a function of the total deformation gradient and the active stress as a function of both the total deformation gradient and its active part. We show that this novel approach combines the features of both the classical stress-based Hill model and the recent active-strain models. While the notion of active stress is rather phenomenological in nature, active strain is micro-structurally motivated, physically measurable, and straightforward to calibrate. We demonstrate that our model is capable of simulating excitation-contraction coupling in cardiac muscle with its characteristic features of wall thickening, apical lift, and ventricular torsion.

  12. A disaggregate model for quantifying the safety effects of winter road maintenance activities at an operational level.

    2012-09-01

    This research presents a disaggregated modeling approach for investigating the link between winter road collision occurrence, weather, road surface conditions, traffic exposure, temporal trends and site-specific effects. This approach is unique as it allows for quantification of the safety effects of different winter road maintenance activities at an operational level. Different collision frequency models are calibrated using hourly data collected from 31 different highway routes across Ontario, Canada. It is found that factors such as visibility, precipitation intensity, air temperature, wind speed, exposure, month of the winter season, and storm hour have statistically significant effects on winter road safety. Most importantly, road surface conditions are identified as one of the major contributing factors, representing the first contribution showing the empirical relationship between safety and road surface conditions at such a disaggregate level. The applicability of the modeling framework is demonstrated using several examples, such as quantification of the benefits of alternative maintenance operations and evaluation of the effects of different service standards using safety as a performance measure.

    Biosafety regulatory frameworks are intended to serve as mechanisms for ensuring the safe use of biotechnology products without imposing unacceptable risk to human health or the environment, or unintended constraints to technology transfer. The OECD Blue Book on "Recombinant DNA Safety Considerations", setting out principles and concepts for handling genetically modified organisms safely outside of contained laboratory conditions, was a milestone in the history of biotechnology. The "Recombinant DNA Safety Considerations" definitively became the major resource for the formulation of national regulatory frameworks and international regulations, including the Cartagena Protocol.

    Participation in extracurricular activities is a promising avenue for enhancing students' school motivation. Using self-determination theory (Deci & Ryan, 2000), the goal of this study was to test a serial multiple mediator model. In this model, students' perceptions of autonomy support from their extracurricular activity leader predicted their activity-based intrinsic and identified regulations. In turn, these regulations predicted their school-based intrinsic and identified regulations during the same school year. Finally, these regulations predicted their school-based intrinsic and identified regulations one year later. A total of 276 youths (54% girls) from disadvantaged neighborhoods were surveyed over two waves of data collection. The proposed mediation model was supported for both types of regulation. These results highlight the generalization effects of motivation from the extracurricular activity context to the school context.

    2016-07-12

    A multireference second-order perturbation theory approach based on the generalized active space self-consistent-field (GASSCF) wave function is presented. Compared with the complete active space (CAS) and restricted active space (RAS) wave functions, GAS wave functions are more flexible and can employ larger active spaces and/or different truncations of the configuration interaction expansion. With GASSCF, one can explore chemical systems that are not affordable with either CASSCF or RASSCF. Perturbation theory to second order on top of GAS wave functions (GASPT2) has been implemented to recover the remaining electron correlation. The method has been benchmarked by computing the chromium dimer ground-state potential energy curve. These calculations show that GASPT2 gives results similar to CASPT2 even with a configuration interaction expansion much smaller than the corresponding CAS expansion.

    An appropriate theoretical framework may be useful for guiding the development of physical activity interventions. This review investigates the effectiveness of the protection motivation theory (PMT), a model based on the cognitive mediation processes of behavioral change, in the prediction and promotion of physical activity participation. A literature search was conducted using the databases MEDLINE, PsycINFO, PubMed, and Web of Science, and a manual search was conducted on relevant reference lists. Studies were included if they tested or applied the PMT, measured physical activity, and sampled from healthy populations. A total of 20 studies were reviewed, grouped into four design categories: prediction, stage discrimination, experimental manipulation, and intervention. The results indicated that the PMT's coping appraisal construct of self-efficacy generally appears to be the most effective in predicting and promoting physical activity participation. In conclusion, the PMT shows some promise, however, there are still substantial gaps in the evidence.

    A useful method was developed for the synthesis of active esters by palladium-catalyzed alkoxycarbonylation of (hetero)aromatic bromides. The protocol was general for a range of oxygen nucleophiles including N-hydroxysuccinimide (NHS), pentafluorophenol (PFP), hexafluoroisopropyl alcohol (HFP), 4-nitrophenol, and N-hydroxyphthalimide. A high functional group tolerance was displayed, and several active esters were prepared with good to excellent isolated yields. The protocol was extended to access an important synthetic precursor to the HIV-protease inhibitor, saquinavir, by formation of an NHS ester followed by acyl substitution.

    2016-01-01

    Optically active artificial structures have attracted tremendous research attention. Such structures must meet two requirements: Lack of spatial inversion symmetries and, a condition usually not explicitly considered, the structure shall preserve the helicity of light, which implies that there must be a vanishing coupling between the states of opposite polarization handedness among incident and scattered plane waves. Here, we put forward and demonstrate that a unit cell made from chiraly arranged electromagnetically dual scatterers serves exactly this purpose. We prove this by demonstrating optical activity of such unit cell in general scattering directions.

    The goal for this study was to evaluate safety regarding anticoagulant activity and platelet activation during daily consumption of an aqueous cyanophyta extract (ACE), containing a high dose of phycocyanin. Using a randomized, double-blind, placebo-controlled study design, 24 men and women were enrolled after informed consent, and consumed either ACE (2.3 g/day) or placebo daily for 2 weeks. The ACE dose was equivalent to ∼1 g phycocyanin per day, chosen based on the highest dose Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration. Consuming ACE did not alter markers for platelet activation (P-selectin expression) or serum P-selectin levels. No changes were seen for activated partial thromboplastin time, thrombin clotting time, or fibrinogen activity. Serum levels of aspartate transaminase (AST) showed a significant reduction after 2 weeks of ACE consumption (P < .001), in contrast to placebo where no changes were seen; the difference in AST levels between the two groups was significant at 2 weeks (P < .02). Reduced levels of alanine transaminase (ALT) were also seen in the group consuming ACE (P < .08). Previous studies showed reduction of chronic pain when consuming 1 g ACE per day. The higher dose of 2.3 g/day in this study was associated with significant reduction of chronic pain at rest and when physically active (P < .05). Consumption of ACE showed safety regarding markers pertaining to anticoagulant activity and platelet activation status, in conjunction with rapid and robust relief of chronic pain. Reduction in AST and ALT suggested improvement in liver function and metabolism.

    2016-09-01

    Young people have a large burden of death and disease from risky road behaviours. Guidelines recommend injury prevention and harm minimisation counselling; however, little is known about road risks in youth attending primary care. The aim of this study was to examine the type of road risks and associated behaviours in young people attending general practice. A cross-sectional analysis was undertaken on health risk survey data from a sample of 901 patients, aged 14-24 years, attending 40 Victorian general practices in a stratified cluster randomised trial. Frequently occurring road risks included travelling with people under the influence of alcohol or drugs (55%), speeding (43%) and mobile phone use (40%). These behaviours were strongly associated with other health risks, including use of tobacco, alcohol and illicit drugs, and unprotected sex. High proportions of youth attending general practice engage in road risks, making this a potential setting to discuss road risks along with broader health risk prevention activities.

  13. Safety at CERN

    CERN Multimedia

    2009-01-01

    Safety is an integral part of our working lives, and should be in our minds whatever job we do at CERN. Ultimately, safety is the responsibility of the Director General – your safety is my concern. That’s why I have this week appointed a new Safety Policy Committee (SAPOCO) that reflects the new Organizational structure of CERN. CERN’s Staff Rules and Regulations clearly lay out in chapter 3 the scope of safety at CERN as well as my responsibilities and yours in safety matters. At CERN, safety is considered in the broadest sense, encompassing occupational Health and Safety, environmental protection, and the safety of equipment and installations. It is my responsibility to put appropriate measures in place to ensure that these conditions are met. And it is the responsibility of us all to ensure that we are fully conversant with safety provisions applicable in our areas of work and that we comply with them. The appointment of a n...

  15. Inflammatory cytokines in general and central obesity and modulating effects of physical activity.

    Directory of Open Access Journals (Sweden)

    Frank M Schmidt

    Full Text Available Chronic systemic inflammation in obesity originates from local immune responses in visceral adipose tissue. However, assessment of a broad range of inflammation-mediating cytokines and their relationship to physical activity and adipometrics has scarcely been reported to date.To characterize the profile of a broad range of pro- and anti-inflammatory cytokines and the impact of physical activity and energy expenditure in individuals with general obesity, central obesity, and non-obese subjects.A cross-sectional study comprising 117 obese patients (body mass index (BMI ≥ 30 and 83 non-obese community-based volunteers.Serum levels of interleukin (IL-2, IL-4, IL-5, IL-10, IL-12, IL-13, granulocyte-macrophage colony-stimulating factor (GM-CSF, interferon (IFN-γ and tumor necrosis factor (TNF-α were measured. Physical activity and energy expenditure (MET were assessed with actigraphy. Adipometrics comprised BMI, weight, abdominal-, waist- and hip-circumference, waist to hip ratio (WHR, and waist-to-height-ratio (WHtR.General obesity was associated with significantly elevated levels of IL-5, IL-10, IL-12, IL-13, IFN-γ and TNF-α, central obesity with significantly elevated IL-5, IL-10, IL-12, IL-13 and IFN-γ-levels. In participants with general obesity, levels of IL-4, IL-10 and IL-13 were significantly elevated in participants with low physical activity, even when controlled for BMI which was negatively associated with physical acitivity. Cytokines significantly correlated with adipometrics, particularly in obese participants.Results confirm up-regulation of certain pro- and anti-inflammatory cytokines in obesity. In obese subjects, physical activity may lower levels and thus reduce pro-inflammatory effects of cytokines that may link obesity, insulin resistance and diabetes.

    2012-03-01

    Full Text Available Abstract Background The use of increasingly complex payment schemes in primary care may represent a barrier to recruiting general practitioners (GP. The existing Norwegian remuneration system is fully activity based - 2/3 fee-for-service and 1/3 capitation. Given that the system has been designed and revised in close collaborations with the medical association, it is likely to correspond - at least to some degree - with the preferences of current GPs (men in majority. The objective of this paper was to study which preferences that young doctors (women in majority, who are the potential entrants to general practice have for activity based vs. salary based payment systems. Methods In November-December 2010 all last year medical students and all interns in Norway (n = 1.562 were invited to participate in an online survey. The respondents were asked their opinion on systems of remuneration for GPs; inclination to work as a GP; risk attitude; income preferences; work pace tolerance. The data was analysed using one-way ANOVA and multinomial logistic regression analysis. Results A total of 831 (53% responded. Nearly half the sample (47% did not consider the remuneration system to be important for their inclination to work as GP; 36% considered the current system to make general practice more attractive, while 17% considered it to make general practice less attractive. Those who are attracted by the existing system were men and those who think high income is important, while those who are deterred by the system are risk averse and less happy with a high work pace. On the question of preferred remuneration system, half the sample preferred a mix of salary and activity based remuneration (the median respondent would prefer a 50/50 mix. Only 20% preferred a fully activity based system like the existing one. A salary system was preferred by women, and those less concerned with high income, while a fully activity based system was preferred by men, and those

    The present study evaluates eating habits and behaviors, and nutritional and food safety knowledge of a group of Italian adolescents. A dietary questionnaire previously constructed and tested was self-administered during school time. Each section was evaluated using a separate score. The study was carried out as a part of a nutritional surveillance project in the Aosta Valley Region, Northern Italy. Five hundred and thirty-two adolescent subjects, aged 15.4 +/- 0.7 years, attending the second year of secondary schools participated in the study. We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting healthy food choices, nutritional and food safety, weight, height, Body Mass Index (BMI). Only 37.0% of the sample have satisfactory eating habits; 18.5% have a very active lifestyle; only 8.6% have quite good nutritional knowledge, 2.4% have satisfactory food safety knowledge, although 43.7% have good hygiene practices. The results point out unhealthy behaviors influencing adolescents' eating habits and suggest which of these must be considered in order to develop tailored nutrition interventions, improving adolescents' consciousness aimed at adopting a healthy lifestyle.

    LIN,Jun; Hjalmar Skarphedinsson; Stepehen G.Davies

    2004-01-01

    @@ Solid-phase asymmetric organic synthesis has become a very important synthetic strategy within the organic chemistry community.[1] Critical to success in SPOS is a linking strategy which allows both the substrate to be loaded and the product released efficiently from the polymeric support. A safety catch linker[2] (SCL) is in principle a linking molecule orthogonal to the reaction conditions of the library synthesis, which can be easily activated by a simple chemical transformation to allow efficient cleavage of the products from the polymer under mild conditions. In order to introduce the SuperQuat chiral auxiliaries[3] for SOPS, we report herein design and synthesis of a novel safety catch linker for asymmetric conjugate addition reactions.

    2006-04-06

    An inactin-anesthetized rat cardiovascular (CV) assay was employed in a screening mode to triage multiple classes of melanin-concentrating hormone receptor 1 (MCHr1) antagonists. Lead identification was based on a compound profile producing high drug concentration in both plasma (>40 microM) and brain (>20 microg/g) with optimization activities on multiple classes of MCHr1 antagonists were terminated. After providing evidence that the cardiovascular liabilities were not a function of MCHr1 antagonism, continued screening identified the chromone-substituted aminopiperidine amides as a class of MCHr1 antagonists that demonstrated a safe cardiovascular profile at high drug concentrations in both plasma and brain. The high incidence of adverse cardiovascular effects associated with an array of MCHr1 antagonists of significant chemical diversity, combined with the stringent safety requirements for antiobesity drugs, highlight the importance of incorporating cardiovascular safety assessment early in the lead selection process.

    2014-01-01

    The characteristics of safety management on nuclear power engineering in general contracting mode, which were different from the common construction projects, were analyzed.Then the main problems in current safety management of nuclear power engineering construction were put forward, such as lagging of relevant laws and regulations, the contradiction between expansion of nuclear power construction project and lack of human resources, the labor subcontracting system and safety problems brought by its working personnel, and passive regulation of safety production costs etc.These problems would directly impact the existing work safety defense line, and bring unprecedented challenge to safety management work of general contractor.So the suggestions and countermeasures were put forward, including that the relevant government departments should publish the relevant laws and regula-tions about general contracting of project as soon as possible, the general contractor should fully integrate on-site safety management resources, strengthen the safety management on subcontractors, strengthen safety training of the labor service personnel, and explore the management mode of work safety costs.%首先分析了总承包模式下核电工程建设不同于一般建设工程安全管理的特点,提出目前工作中存在的主要问题,包括相关法律法规的滞后、核电建设工程扩张与人力资源不足之间的矛盾、劳务分包体制及其作业人员引起的相关问题以及安全生产费用监管被动等,这些都直接冲击现有的安全生产防线,并给总承包单位安全管理工作带来前所未有的挑战。为此,提出以下建议和对策措施:有关部门尽快出台总承包工程相关法律法规;总承包单位应充分整合现场安全管理资源,加大对分包单位安全管理力度,加强劳务作业人员安全培训,探索安全生产费用管理模式等。

  5. Application of viability theory for road vehicle active safety during cornering manoeuvres

    Vandanjon, P.-O.; Coiret, A.; Lorino, T.

    2014-02-01

    Viability theory proposes geometric metaphors in addition to classical ordinary differential equation analysis. In this paper, advantages of applying viability theory to road safety domain are presented. The exact issue is to determine if, from an initial state of a vehicle/road/driver system, a soft controls strategy is compatible with a safe driving sequence. The case of a car negotiating a curve is considered. The application of the viability theory to this issue offers the advantage to avoid classical full computing of the system. Instead of that, it consists on verifying that the states and the controls belong to a subset called the viability kernel. The construction and the use of the viability kernel for a vehicle system dynamic is proposed by using support vector machines algorithm. Then, the applicability of this theory is demonstrated through experimental tests. This innovative application of the viability theory to vehicle dynamics with road safety concerns could benefit to robust embedded warning systems.

  6. Activation of hypoxia inducible factor 1 is a general phenomenon in infections with human pathogens.

    Directory of Open Access Journals (Sweden)

    Nadine Werth

    Full Text Available BACKGROUND: Hypoxia inducible factor (HIF-1 is the key transcriptional factor involved in the adaptation process of cells and organisms to hypoxia. Recent findings suggest that HIF-1 plays also a crucial role in inflammatory and infectious diseases. METHODOLOGY/PRINCIPAL FINDINGS: Using patient skin biopsies, cell culture and murine infection models, HIF-1 activation was determined by immunohistochemistry, immunoblotting and reporter gene assays and was linked to cellular oxygen consumption. The course of a S. aureus peritonitis was determined upon pharmacological HIF-1 inhibition. Activation of HIF-1 was detectable (i in all ex vivo in biopsies of patients suffering from skin infections, (ii in vitro using cell culture infection models and (iii in vivo using murine intravenous and peritoneal S. aureus infection models. HIF-1 activation by human pathogens was induced by oxygen-dependent mechanisms. Small colony variants (SCVs of S. aureus known to cause chronic infections did not result in cellular hypoxia nor in HIF-1 activation. Pharmaceutical inhibition of HIF-1 activation resulted in increased survival rates of mice suffering from a S. aureus peritonitis. CONCLUSIONS/SIGNIFICANCE: Activation of HIF-1 is a general phenomenon in infections with human pathogenic bacteria, viruses, fungi and protozoa. HIF-1-regulated pathways might be an attractive target to modulate the course of life-threatening infections.

    2014-11-01

    Conventional repetitive control has proven to be an effective strategy to reject/track periodic signals with constant frequency; however, it shows poor performance in varying frequency applications. This paper proposes an active disturbance rejection methodology applied to a large class of uncertain flat systems for the tracking and rejection of periodic signals, in which the possibilities of the generalized proportional integral (GPI) observer-based control to address repetitive control problems are studied. In the proposed scheme, model uncertainties and external disturbances are lumped together in a general additive disturbance input that is estimated and rejected on-line. An illustrative case study of mechatronic nature is considered. Experimental results show that the proposed GPI observer-based control successfully rejects periodic disturbances even under varying speed conditions.

    2013-01-01

    Active control of turbine blade tip clearance continues to be a concern in design and con-trol of gas turbines. Ever increasing demands for improved efficiency and higher operating temper-atures require more stringent tolerances on turbine tip clearance. In this paper, a turbine tip clearance control apparatus and a model of turbine tip clearance are proposed;an implicit active generalized predictive control (GPC), with auto-regressive (AR) error modification and fuzzy adjustment on control horizon, is presented, as well as a quantitative analysis method of robust per-turbation radius of the system. The active clearance control (ACC) of aero-engine turbine tip clear-ance is evaluated in a lapse-rate take-off transient, along with the comparative and quantitative analysis of the stability and robustness of the active tip clearance control system. The results show that the resultant active tip clearance control system with the improved GPC has favorable steady-state and dynamic performance and benefits of increased efficiency, reduced specific fuel consump-tion, and additional service life.

    The EUROSAFE Forum for Nuclear Safety is part of the EUROSAFE approach, which consists of two further elements: the EUROSAFE Tribune and the EUROSAFE Web site. The general aim of EUROSAFE is to contribute to fostering the convergence of technical nuclear safety practices in a broad European context. This is done by providing technical safety and research organisations, safety authorities, power utilities, the rest of the industry and non-governmental organisations mainly from the European Union and East-European countries, and international organisations with a platform for the presentation of recent analyses and R and D in the field of nuclear safety. The goal is to share experiences, to exchange technical and scientific opinions, and to conduct debates on key issues in the fields of nuclear safety and radiation protection. The EUROSAFE Forum on 2005 focused on Safety Improvements, Reasons - Strategies - Implementation, from the point of view of the authorities, TSOs and industry. Latest work in nuclear installation safety and research, waste management, radiation safety as well as nuclear material and nuclear facilities security carried out by GRS, IRSN, AVN and their partners in the European Union, Switzerland and Eastern Europe are presented. A high level of nuclear safety is a priority for the countries of Europe. The technical safety organisations play an important role in contributing to that objective through appropriate approaches to major safety issues as part of their assessments and research activities. The challenges to nuclear safety are international. Changes in underlying technologies such as instrumentation and control, the impact of electricity market deregulation, demands for improved safety and safety management, the ageing of nuclear facilities, waste management, maintaining and improving scientific and technical knowledge, and the need for greater transparency - these are all issues where the value of an international approach is gaining

    Computer-based quantitative structure-activity relationship (QSAR) model has been becoming a powerful tool in understanding the structural requirements for chemicals to bind the estrogen receptor (ER), designing drugs for human estrogen replacement therapy, and identifying potential estrogenic endocrine disruptors, in this study, a simple yet powerful neural network technique, generalized regression neural network (GRNN) was used to develop a QSAR model based on 131 structurally diverse estrogens (training set). Only nine descriptors calculated solely from the molecular structures of compounds selected by objective and subjective feature selections were used as inputs of the GRNN model. The predictive power of the built model was found to be comparable to that of the more traditional techniques but requiring significantly easy implementation and a shorter computation-time. The obtained result indicates that the proposed GRNN model is robust and satisfactory, and can provide a feasible and practical tool for the rapid screening of the estrogenic activity of organic compounds.

    Boron is an essential micronutrient for plants, and it is beneficial for animals. However, at high concentrations boron is toxic to cells although the mechanism of this toxicity is not known. Atr1 has recently been identified as a boron efflux pump whose expression is upregulated in response to boron treatment. Here, we found that the expression of ATR1 is associated with expression of genes involved in amino acid biosynthesis. These mechanisms are strictly controlled by the transcription factor Gcn4 in response to boron treatment. Further analyses have shown that boron impaired protein synthesis by promoting phosphorylation of eIF2α in a Gcn2 kinase dependent manner. The uncharged tRNA binding domain (HisRS) of Gcn2 is necessary for the phosphorylation of eIF2α in the presence of boron. We postulate that boron exerts its toxic effect through activation of the general amino acid control system and inhibition of protein synthesis. Since the general amino acid control pathway is conserved among eukaryotes, this mechanism of boron toxicity may be of general importance. PMID:22114689

    Full Text Available Boron is an essential micronutrient for plants, and it is beneficial for animals. However, at high concentrations boron is toxic to cells although the mechanism of this toxicity is not known. Atr1 has recently been identified as a boron efflux pump whose expression is upregulated in response to boron treatment. Here, we found that the expression of ATR1 is associated with expression of genes involved in amino acid biosynthesis. These mechanisms are strictly controlled by the transcription factor Gcn4 in response to boron treatment. Further analyses have shown that boron impaired protein synthesis by promoting phosphorylation of eIF2α in a Gcn2 kinase dependent manner. The uncharged tRNA binding domain (HisRS of Gcn2 is necessary for the phosphorylation of eIF2α in the presence of boron.

    Full Text Available INTRODUCTION: This study was developed to evaluate the situation of leprosy in the general population of the municipality of Buriticupu, State of Maranhão, Brazil. METHODS: We used the method of active search to identify new cases from 2008 to 2010. Bacilloscopy of intradermal scrapings was performed in all patients with skin lesions compatible with leprosy, and histopathological examination in those who had doubts on the definition of the clinical form. RESULTS: The study included 19,104 individuals, with 42 patients diagnosed with leprosy after clinical examination, representing a detection rate of 219.84 per 100,000 inhabitants. The predominant clinical presentation was tuberculoid with 24 (57.1% cases, followed by borderline with 11, indeterminate with four, and lepromatous with three cases. The study also allowed the identification of 81 patients with a history of leprosy and other skin diseases, such as pityriasis versicolor, dermatophytosis, scabies, vitiligo, and skin carcinoma. The binomial test showed that the proportion of cases in the headquarters was significantly higher than that in the villages (p = 0.04, and the generalized exact test showed that there was no association between age and clinical form (p = 0.438 and between age and gender (p = 0.083. CONCLUSIONS: The elevated detection rate defines the city as hyperendemic for leprosy; the active search for cases, as well as the organization of health services, is an important method for disease control.

  5. Accounting for medical variation: the case of prescribing activity in a New Zealand general practice sample.

    Davis, P B; Yee, R L; Millar, J

    1994-08-01

    Medical practice variation is extensive and well documented, particularly for surgical interventions, and raises important questions for health policy. To date, however, little work has been carried out on interpractitioner variation in prescribing activity in the primary care setting. An analytical model of medical variation is derived from the literature and relevant indicators are identified from a study of New Zealand general practice. The data are based on nearly 9,500 completed patient encounter records drawn from over a hundred practitioners in the Waikato region of the North Island, New Zealand. The data set represents a 1% sample of all weekday general practice office encounters in the Hamilton Health District recorded over a 12-month period. Overall levels of prescribing, and the distribution of drug mentions across diagnostic groupings, are broadly comparable to results drawn from international benchmark data. A multivariate analysis is carried out on seven measures of activity in the areas of prescribing volume, script detail, and therapeutic choice. The analysis indicates that patient, practitioner and practice attributes exert little systematic influence on the prescribing task. The principal influences are diagnosis, followed by practitioner identity. The pattern of findings suggests also that the prescribing task cannot be viewed as an undifferentiated activity. It is more usefully considered as a process of decision-making in which 'core' judgements--such as the decision to prescribe and the choice of drug--are highly predictable and strongly influenced by diagnosis, while 'peripheral' features of the task--such as choosing a combination drug or prescribing generically--are less determinate and more subject to the exercise of clinical discretion.(ABSTRACT TRUNCATED AT 250 WORDS)

    This document is a self-study and classroom guide, for criticality safety of activities with fissile materials outside nuclear reactors. This guide provides a basic overview of criticality safety and criticality accident prevention methods divided into three parts: theory, application, and history. Except for topic emphasis, theory and history information is general, while application information is specific to the Idaho National Engineering and Environmental Laboratory (INEEL). Information presented here should be useful to personnel who must know criticality safety basics to perform their assignments safely or to design critically safe equipment or operations. However, the guide's primary target audience is fissile material handler candidates.

    Management of Nuclear Safety, Industrial Safety, Industrial Hygiene, and Fire Protection programs, functions, and field support resources for Tank Waste Remediation Systems (TWRS) has, until recently, been centralized in TWRS Safety, under the Emergency, Safety, and Quality organization. Industrial hygiene technician services were also provided to support operational needs related to safety basis compliance. Due to WHC decentralization of safety and reengineering efforts in West Tank Farms, staffing and safety responsibilities have been transferred to the facilities. Under the new structure, safety personnel for TWRS are assigned directly to East Tank Farms, West Tank Farms, and a core Safety Group in TWRS Engineering. The Characterization Project Operations (CPO) safety organization will remain in tact as it currently exists. Personnel assigned to East Tank Farms, West Tank Farms, and CPO will perform facility-specific or project-specific duties and provide field implementation of programs. Those assigned to the core group will focus on activities having a TWRS-wide or programmatic focus. Hanford-wide activities will be the responsibility of the Safety Center of Expertise. In order to ensure an effective and consistent safety program for TWRS under the new organization program functions, goals, organizational structure, roles, responsibilities, and path forward must be clearly established. The purpose of the TWRS Safety Program Plan is to define the overall safety program, responsibilities, relationships, and communication linkages for safety personnel under the new structure. In addition, issues associated with reorganization transition are addressed, including training, project ownership, records management, and dissemination of equipment. For the purpose of this document ``TWRS Safety`` refers to all safety professionals and technicians (Industrial Safety, Industrial Hygiene, Fire Protection, and Nuclear Safety) within the TWRS organization, regardless of their

    This article reviews the results and conclusions from four pivotal and two comparative clinical trials. The six randomized, controlled, single-blinded, parallel-group clinical trials were conducted to determine which antiseptic is best for use as a patient preoperative skin preparation. The objective of these studies was to compare the immediate, persistent (residual), and cumulative antimicrobial efficacy and safety of 2% chlorhexidine gluconate (CHG) combined with 70% isopropyl alcohol (IPA) (ChloraPrep); another combination CHG and IPA antiseptic (CHG+IPA) and 2% aqueous CHG alone; 4% CHG (Hibiclens) alone; 70% isopropyl alcohol (IPA) alone; and an iodine-containing solution, 10% povidone-iodine (Betadine) alone as preoperative skin topical antiseptics for potential prevention of nosocomial infections.

  9. Further research on the biological activities and the safety of raspberry ketone is needed

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Raspberry ketone supplements have grabbed consumer attention with the possibility that they might help burn fat and aid weight loss. While raspberry ketone occurs naturally, and is found in raspberry fruit, most is synthetically produced for use in commercial products as flavorings, fragrances, or dietary supplements. Currently, the amount of raspberry ketone in dietary supplements (currently sold in the US is well above the maximum concentration recommended for food and fragrance products, so additional toxicology work is needed to ensure that such concentrations of raspberry ketone are safe. In addition to safety data, clinical studies are also needed to validate any health benefits. Without research on the effects of consuming high concentrations of raspberry ketone, consumers should be wary of unsubstantiated claims and mindful of potential harm to their health.

  12. A generalized finite difference method for modeling cardiac electrical activation on arbitrary, irregular computational meshes.

    Trew, Mark L; Smaill, Bruce H; Bullivant, David P; Hunter, Peter J; Pullan, Andrew J

    2005-12-01

    A generalized finite difference (GFD) method is presented that can be used to solve the bi-domain equations modeling cardiac electrical activity. Classical finite difference methods have been applied by many researchers to the bi-domain equations. However, these methods suffer from the limitation of requiring computational meshes that are structured and orthogonal. Finite element or finite volume methods enable the bi-domain equations to be solved on unstructured meshes, although implementations of such methods do not always cater for meshes with varying element topology. The GFD method solves the bi-domain equations on arbitrary and irregular computational meshes without any need to specify element basis functions. The method is useful as it can be easily applied to activation problems using existing meshes that have originally been created for use by finite element or finite difference methods. In addition, the GFD method employs an innovative approach to enforcing nodal and non-nodal boundary conditions. The GFD method performs effectively for a range of two and three-dimensional test problems and when computing bi-domain electrical activation moving through a fully anisotropic three-dimensional model of canine ventricles.

    G-quadruplexes (G4s) are four-stranded nucleic acid structures adopted by some repetitive guanine-rich sequences. Putative G-quadruplex-forming sequences (PQSs) are highly prevalent in human genome. Recently some G4s have been reported to have cancer-selective antiproliferative activity. A G4 DNA, AS1411, is currently in phase II clinical trials as an anticancer agent, which is reported to bind tumor cells by targeting surface nucleolin. AS1411 also has been extensively investigated as a target-recognition element for cancer cell specific drug delivery or cancer cell imaging. Here we show that, in addition to AS1411, intramolecular G4s with parallel structure (including PQSs in genes) have general binding activity to many cell lines with different affinity. The binding of these G4s compete with each other, and their targets are certain cellular surface proteins. The tested G4s exhibit enhanced cellular uptake than non-G4 sequences. This uptake may be through the endosome/lysosome pathway, but it is independent of cellular binding of the G4s. The tested G4s also show selective antiproliferative activity that is independent of their cellular binding. Our findings provide new insight into the molecular recognition of G4s by cells; offer new clues for understanding the functions of G4s in vivo, and may extend the potential applications of G4s.

    The Italian National Center for Hadrontherapy (CNAO, Centro Nazionale di Adroterapia Oncologica), a synchrotron-based hospital facility, started the treatment of patients within selected clinical trials in late 2011 and 2012 with actively scanned proton and carbon ion beams, respectively. The activation of a new clinical protocol for the irradiation of uveal melanoma using the existing general-purpose proton beamline is foreseen for late 2014. Beam characteristics and patient treatment setup need to be tuned to meet the specific requirements for such a type of treatment technique. The aim of this study is to optimize the CNAO transport beamline by adding passive components and minimizing air gap to achieve the optimal conditions for ocular tumor irradiation. The CNAO setup with the active and passive components along the transport beamline, as well as a human eye-modeled detector also including a realistic target volume, were simulated using the Monte Carlo Geant4 toolkit. The strong reduction of the air gap between the nozzle and patient skin, as well as the insertion of a range shifter plus a patient-specific brass collimator at a short distance from the eye, were found to be effective tools to be implemented. In perspective, this simulation toolkit could also be used as a benchmark for future developments and testing purposes on commercial treatment planning systems.

    Because lubricants may decrease trauma during coitus, it is hypothesized that they could aid in the prevention of HIV acquisition. Therefore, safety and anti-HIV-1 activity of over-the-counter (OTC) aqueous- (n = 10), lipid- (n = 2), and silicone-based (n = 2) products were tested. The rheological properties of the lipid-based lubricants precluded testing with the exception of explant safety testing. Six aqueous-based gels were hyperosmolar, two were nearly iso-osmolar, and two were hypo-osmolar. Evaluation of the panel of products showed Gynol II (a spermicidal gel containing 2% nonoxynol-9), KY Jelly, and Replens were toxic to Lactobacillus. Two nearly iso-osmolar aqueous- and both silicone-based gels were not toxic toward epithelial cell lines or ectocervical or colorectal explant tissues. Hyperosmolar lubricants demonstrated reduction of tissue viability and epithelial fracture/sloughing while the nearly iso-osmolar and silicon-based lubricants showed no significant changes in tissue viability or epithelial modifications. While most of the lubricants had no measurable anti-HIV-1 activity, three lubricants which retained cell viability did demonstrate modest anti-HIV-1 activity in vitro. To determine if this would result in protection of mucosal tissue or conversely determine if the epithelial damage associated with the hyperosmolar lubricants increased HIV-1 infection ex vivo, ectocervical tissue was exposed to selected lubricants and then challenged with HIV-1. None of the lubricants that had a moderate to high therapeutic index protected the mucosal tissue. These results show hyperosmolar lubricant gels were associated with cellular toxicity and epithelial damage while showing no anti-viral activity. The two iso-osmolar lubricants, Good Clean Love and PRÉ, and both silicone-based lubricants, Female Condom 2 lubricant and Wet Platinum, were the safest in our testing algorithm.

    Work equipment and installations with a high risk for health and safety of employees should be paid a special attention. The German Product Safety Act, which is aimed to manufacturers or distributors in order to protect consumers, maintains a conclusive catalogue of these so-called "installations in need of monitoring" fixing the work equipment and installations for which such special inspections can be demanded. This catalogue has remained unchanged for decades and has been transformed nearly unmodified into the Plant Safety Ordinance. Currently, there is a discussion about this catalogue in Germany. A major point of concern is the definition and the significance of "especially" dangerous work equipment and installations. Two recent research projects are dealing with the problem how to define "especially".

    The safe operation of a semi-batch catalytic reactor remains a sensitive issue when highly exothermic side reactions may occur, and various elements such as controllability, stability, safety, and economic aspects have to be considered in the process development. Nominal operating conditions are set to avoid excessive thermal sensitivity to variations in the process parameters. Several shortcuts or model-based methods are used to estimate the safety limits and runaway boundaries for the op...

  1. Parsec-scale Faraday Rotation Measures from General Relativistic MHD Simulations of Active Galactic Nuclei Jets

    Broderick, Avery E

    2010-01-01

    For the first time it has become possible to compare global 3D general relativistic magnetohydrodynamic (GRMHD) jet formation simulations directly to very-long baseline interferometric multi-frequency polarization observations of the pc-scale structure of active galactic nucleus (AGN) jets. Unlike the jet emission, which requires post hoc modeling of the non-thermal electrons, the Faraday rotation measures (RMs) depend primarily upon simulated quantities and thus provide a robust way in which to confront simulations with observations. We compute RM distributions of 3D global GRMHD jet formation simulations, with which we explore the dependence upon model and observational parameters, emphasizing the signatures of structures generic to the theory of MHD jets. With typical parameters, we find that it is possible to reproduce the observed magnitudes and many of the structures found in AGN jet RMs, including the presence of transverse RM gradients. In our simulations the RMs are generated within a smooth extensio...

  2. Assessment of food safety risks associated with preslaughter activities during the traditional slaughter of goats in Gauteng, South Africa.

    2014-06-01

    The South African Department of Agriculture, Forestry and Fisheries estimated in 2012 that there were 2.033 million goats in the country. Of these animals, less than 0.5% are slaughtered at registered abattoirs. Although informal and traditional slaughter of goats for home consumption is permitted under the South African Meat Safety Act 40 of 2000, the responsibility for ensuring that products are safe is left to the traditional or ritual slaughter practitioners. The objective of the present study was to assess whether preslaughter activities associated with traditional or ritual slaughter promote or reduce food-associated risks and to recommend mitigation strategies for potential food safety hazards. Structured interviews were conducted with 105 selected respondents (in and around Tshwane, South Africa) who had been involved in traditional goat slaughter. Approximately 70% of goats slaughtered were obtained from sources that could be traced to ascertain the origin of the goats. None of the respondents were aware of the need for a health declaration for slaughter stock. Some slaughter practitioners (21%) perform prepurchase inspection of stock to ascertain their health status. However, this percentage is very small, and the approach is based on indigenous knowledge systems. The majority of respondents (67.6%) travelled 1 to 11 km to obtain a goat for traditional slaughter. Although approximately 70% of slaughter goats were transported by vehicles, the vehicles used did not meet the legal standard. More than two-thirds of goats were tied to a tree while waiting to be slaughtered, and the rest were held in a kraal. The holding period ranged from 1 to 72 h, but more than 70% of the animals were slaughtered within 36 h. This study revealed that traditional and ritual slaughter involves some preslaughter activities with potential to mitigate the risk of slaughtering animals that are not fit for human consumption. Such activities include prepurchase inspection, obtaining

  3. A General Methodology for Evaluation of Carbon Sequestration Activities and Carbon Credits

    Energy Technology Data Exchange (ETDEWEB)

    Klasson, KT

    2002-12-23

    A general methodology was developed for evaluation of carbon sequestration technologies. In this document, we provide a method that is quantitative, but is structured to give qualitative comparisons despite changes in detailed method parameters, i.e., it does not matter what ''grade'' a sequestration technology gets but a ''better'' technology should receive a better grade. To meet these objectives, we developed and elaborate on the following concepts: (1) All resources used in a sequestration activity should be reviewed by estimating the amount of greenhouse gas emissions for which they historically are responsible. We have done this by introducing a quantifier we term Full-Cycle Carbon Emissions, which is tied to the resource. (2) The future fate of sequestered carbon should be included in technology evaluations. We have addressed this by introducing a variable called Time-adjusted Value of Carbon Sequestration to weigh potential future releases of carbon, escaping the sequestered form. (3) The Figure of Merit of a sequestration technology should address the entire life-cycle of an activity. The figures of merit we have developed relate the investment made (carbon release during the construction phase) to the life-time sequestration capacity of the activity. To account for carbon flows that occur during different times of an activity we incorporate the Time Value of Carbon Flows. The methodology we have developed can be expanded to include financial, social, and long-term environmental aspects of a sequestration technology implementation. It does not rely on global atmospheric modeling efforts but is consistent with these efforts and could be combined with them.

    Full Text Available Abstract Background The number of chronically ill patients increases every year. This is partly due to an unhealthy lifestyle. However, the frequency and quality of (evidence-based health promotion activities conducted by Dutch general practitioners (GPs and practice nurses (PNs are limited. The aim of this pilot study was to explore which lifestyle interventions Dutch GPs and PNs carry out in primary care, which barriers and facilitators can be identified and what main topics are with respect to attitudes towards health promoting activities. These topic areas will be identified for a future, larger scale study. Method This qualitative study consisted of 25 semi-structured interviews with sixteen GPs and nine PNs. ATLAS.ti was used to analyse the transcripts of the interviews. Results All GPs and PNs said they discuss lifestyle with their patients. Next to this, GPs and PNs counsel patients, and/or refer them to other disciplines. Only few said they refer patients to specific lifestyle programs or interventions in their own practice or in the neighbourhood. Several barriers and facilitators were identified. The main topics as barriers are: a lack of patients’ motivation to make lifestyle changes, insufficient reimbursement, a lack of proven effectiveness of interventions and a lack of overview of health promoting programs in their neighbourhood. The most cited facilitators are availability of a PN, collaboration with other disciplines and availability of interventions in their own practice. With respect to attitudes, six different types of GPs were identified reflecting the main topics that relate to attitudes, varying from ‘ignorer’ to ‘nurturer’. The topics relating to PNs attitudes towards health promotion activities, were almost unanimously positive. Conclusion GPs and PNs all say they discuss lifestyle issues with their patients, but the health promotion activities that are organized in their practice vary. Main topics that hinder

    Cyclosporine for microemulsion has been widely used in the treatment of rheumatoid arthritis (RA) with remarkably good results over progression of joint damage, as reported by the GRISAR Study. A local group in Argentina, performed a prospective, open label study (Neo-Ra-02), consisting of 12 centres which recruited 50 RA patients, who were followed during 6 months in order to assess efficacy, tolerability and safety of cyclosporine microemulsion in the treatment of RA. Efficacy parameters were: morning stiffness, functional evaluation (HAQ, Lee and Ritchie index) and laboratory and radiological (Larsen score) assessments. Safety parameters were: blood pressure and renal, liver and hematological laboratory data. Patients criteria for participation were: presence of active RA (as defined by the ACR), Steinbrocker anatomic and functional grade I to III, disease evolution no longer than 5 years, no previous history of hypertension, renal or liver disease and absence of DMARDs use during the previous 2 months. There was a statistically significant decrease in morning stiffness and in pain evolution. Improvement became evident after 4 weeks of treatment. Reduction of Ritchie index was significant also at 4 weeks and the same observation was made with tenderness and swollen joint scores. Regarding evolution of CRP and RF, a statistically significant reduction was observed only in positive RF. Safety parameters showed no significant increase in serum creatinine or uric acid: 6/50 patients developed mild hypertension with only a significant increase in systolic blood pressure in comparison with baseline. Cyclosporine microemulsion demonstrated efficacy with minimal adverse events (12% mild hypertension) when appropriately monitored and administered in low doses (3 mg/kg/day).

    Animal-assisted activities (AAA) and animal-assisted therapy (AAT) programs are increasing in popularity, but current programs vary in their safety and health policies. Veterinarians can have an important role in ensuring the safety of both the animals and humans involved, but it is unclear how best to educate veterinary students to serve effectively in this role. Therefore, the goal of this study was to assess the knowledge gaps and perceptions of first-year veterinary students on health and safety aspects of AAA/AAT programs by administering a survey. This information could then guide future educational training in veterinary schools to address the knowledge gaps in this area. Formal education during the veterinary curriculum had not yet been provided to these students on AAA/AAT before the survey. Of 98 first-year veterinary students, 91 completed the survey. When asked about policies on visiting animals, 58% of students responded that nursing homes are required to have a policy and 67% that hospitals are required to have one. Three-quarters of students reported that veterinarians, animal handlers, and facilities should share the responsibility for ensuring safe human-animal interaction in AAA/AAT programs. Most (82%) of the students responded that all or most national and local therapy animal groups prohibit animals that consume raw meat diets from participating in AAA/AAT programs. The results of this survey will help veterinary schools better identify knowledge gaps that can be addressed in veterinary curricula so future veterinarians will be equipped to provide appropriate public health information regarding AAA/AAT programs.

    Full Text Available Degeneration of the lumbar intervertebral discs is irreversible, with no treatment currently available. Building upon experimental studies that demonstrated the importance of the nucleus pulposus (NP in preserving disc structure, we demonstrated that reinsertion of NP cells slowed further disc degeneration and that direct cell-to-cell contact co-culture with mesenchymal stromal cells (MSCs significantly upregulated the viability of NP cells in basic and pre-clinical studies in vitro and in vivo using animal models and human cells. Here, we report a 3-year result of a prospective clinical study, aimed to assess the safety and efficacy of activated NP cell transplantation in the degenerate lumbar intervertebral disc. Candidates were 9 patients aged 20-29 years who had Pfirrmann’s grade III disc degeneration at the level adjacent to the level scheduled for posterior lumbar intervertebral fusion. Viable NP cells from the fused disc were co-cultured in direct contact with autologous bone marrow-derived MSCs. One million activated NP cells were transplanted into the degenerated disc adjacent to the fused level at 7 d after the first fusion surgery. No adverse effects were observed during the 3-year follow-up period. Magnetic resonance imaging did not show any detrimental effects to the transplanted discs and revealed a mild improvement in 1 case. No cases reported any low back pain. Our clinical study confirmed the safety of activated NP cell transplantation, and the findings suggest the minimal efficacy of this treatment to slow the further degeneration of human intervertebral discs.

  10. QSAR study on estrogenic activity of structurally diverse compounds using generalized regression neural network

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Computer-based quantitative structure-activity relationship (QSAR) model has been becoming a pow- erful tool in understanding the structural requirements for chemicals to bind the estrogen receptor (ER), designing drugs for human estrogen replacement therapy, and identifying potential estrogenic endo- crine disruptors. In this study, a simple yet powerful neural network technique, generalized regression neural network (GRNN) was used to develop a QSAR model based on 131 structurally diverse estro- gens (training set). Only nine descriptors calculated solely from the molecular structures of com- pounds selected by objective and subjective feature selections were used as inputs of the GRNN model. The predictive power of the built model was found to be comparable to that of the more traditional techniques but requiring significantly easy implementation and a shorter computation-time. The ob- tained result indicates that the proposed GRNN model is robust and satisfactory, and can provide a feasible and practical tool for the rapid screening of the estrogenic activity of organic compounds.

    Robinson, Brian S; Song, Dong; Berger, Theodore W

    2014-01-01

    This paper presents a methodology to estimate a learning rule that governs activity-dependent plasticity from behaviorally recorded spiking events. To demonstrate this framework, we simulate a probabilistic spiking neuron with spike-timing-dependent plasticity (STDP) and estimate all model parameters from the simulated spiking data. In the neuron model, output spiking activity is generated by the combination of noise, feedback from the output, and an input-feedforward component whose magnitude is modulated by synaptic weight. The synaptic weight is calculated with STDP with the following features: (1) weight change based on the relative timing of input-output spike pairs, (2) prolonged plasticity induction, and (3) considerations for system stability. Estimation of all model parameters is achieved iteratively by formulating the model as a generalized linear model with Volterra kernels and basis function expansion. Successful estimation of all model parameters in this study demonstrates the feasibility of this approach for in-vivo experimental studies. Furthermore, the consideration of system stability and prolonged plasticity induction enhances the ability to capture how STDP affects a neural population's signal transformation properties over a realistic time course. Plasticity characterization with this estimation method could yield insights into functional implications of STDP and be incorporated into a cortical prosthesis.

    Full Text Available Garlic (Allium sativum has been used as a medicinal food since ancient times. However, some people are reluctant to ingest raw garlic due to its unpleasant odor and taste. Therefore, many types of garlic preparations have been developed to reduce these attributes without losing biological functions. Aged black garlic (ABG is a garlic preparation with a sweet and sour taste and no strong odor. It has recently been introduced to Asian markets as a functional food. Extensive in vitro and in vivo studies have demonstrated that ABG has a variety of biological functions such as antioxidant, anti-inflammatory, anti-cancer, anti-obesity, anti-diabetic, anti-allergic, cardioprotective, and hepatoprotective effects. Recent studies have compared the biological activity and function of ABG to those of raw garlic. ABG shows lower anti-inflammatory, anti-coagulation, immunomodulatory, and anti-allergic effects compared to raw garlic. This paper reviews the physicochemical properties, biological activity, health benefits, adverse effects, and general limitations of ABG.

    Two identical single-ascending-dose studies evaluated the safety and pharmacokinetics (PK) of AVI-6002 and AVI-6003, two experimental combinations of phosphorodiamidate morpholino oligomers with positive charges (PMOplus) that target viral mRNA encoding Ebola virus and Marburg virus proteins, respectively. Both AVI-6002 and AVI-6003 were found to suppress disease in virus-infected nonhuman primates in previous studies. AVI-6002 (a combination of AVI-7537 and AVI-7539) or AVI-6003 (a combination of AVI-7287 and AVI-7288) were administered as sequential intravenous (i.v.) infusions of a 1:1 fixed dose ratio of the two subcomponents. In each study, 30 healthy male and female subjects between 18 and 50 years of age were enrolled in six-dose escalation cohorts of five subjects each and received a single i.v. infusion of active study drug (0.005, 0.05, 0.5, 1.5, 3, and 4.5 mg/kg per component) or placebo in a 4:1 ratio. Both AVI-6002 and AVI-6003 were safe and well tolerated at the doses studied. A maximum tolerated dose was not observed in either study. The four chemically similar PMOplus components exhibited generally similar PK profiles. The mean peak plasma concentration and area under the concentration-time curve values of the four components exhibited dose-proportional PK. The estimated plasma half-life of all four components was 2 to 5 h. The safety of the two combinations and the PK of the four components were similar, regardless of the target RNA sequence.

    In the past, variations in the chemical contents (SO42−, Cl−, cations of crater lake water have not systematically demonstrated any relationships with eruptive activity. Intensive parameters (i.e., concentrations, temperature, pH, salinity should be converted into extensive parameters (i.e., fluxes, changes with time of mass and solutes, taking into account all the internal and external chemical–physical factors that affect the crater lake system. This study presents a generalized box model approach that can be useful for geochemical monitoring of active crater lakes, as highly dynamic natural systems. The mass budget of a lake is based on observations of physical variations over a certain period of time: lake volume (level, surface area, lake water temperature, meteorological precipitation, air humidity, wind velocity, input of spring water, and overflow of the lake. This first approach leads to quantification of the input and output fluxes that contribute to the actual crater lake volume. Estimating the input flux of the "volcanic" fluid (Qf- kg/s –– an unmeasurable subsurface parameter –– and tracing its variations with time is the major focus during crater lake monitoring. Through expanding the mass budget into an isotope and chemical budget of the lake, the box model helps to qualitatively characterize the fluids involved. The (calculated Cl− content and dD ratio of the rising "volcanic" fluid defines its origin. With reference to continuous monitoring of crater lakes, the present study provides tips that allow better calculation of Qf in the future. At present, this study offers the most comprehensive and up-to-date literature review on active crater lakes.

    Safety and probiotic characteristics such as antimicrobial activities of three Lactobacillus rhamnosus strains, FSMM15, FSMM22 and FSMM26, previously isolated as potential probiotics from fermented mare's milk were investigated. The three FSMM strains were susceptible to ampicillin, gentamycin, kanamycin, streptomycin, tetracycline and chloramphenicol, whereas they were resistant to erythromycin (minimal inhibitory concentration (MIC) = 4-8 µg/mL) and clindamycin (MIC = 4 µg/mL); bioconversion of bile salts, hemolytic activity and mucin degradation activity were negative; enzymatic activities of α-chymotrypsin and β-glucosidase were detected, but those of α-galactosidase, β-glucuronidase and N-acetyl-β-glucosaminidase, were undetectable. Among the strains, strain FSMM15 was chosen as a safer probiotic candidate due mainly to the lack of plasminogen binding ability. Despite lower acid production of strain FSMM15 than others, its cell-free culture supernatant inhibited growths of Salmonella Typhimurium LT-2, Shigella sonnei, Listeria monocytogenes, and Escherichia coli O157 with comparable levels of ampicillin, suggesting a favorable aspect of strain FSMM15 as a probiotic strain. © 2016 Japanese Society of Animal Science.

    2014-05-01

    This paper focuses on the active safety of a full-vehicle nonlinear model during cornering. At first, a previously developed electronic stability controller (ESC) based on vehicle simplified model is applied to the full-car nonlinear model in order to control the vehicle yaw rate and side-slip angle. The ESC system was shown beneficial not only in tracking the vehicle path as close as possible, but it also helped in reducing the vehicle roll angle and influences ride comfort and road-holding capability; to tackle that issue and also to have better attitude motion, making use of optimal control theory the active suspension control gain is developed from a vehicle linear model and used to compute the active suspension control force of the vehicle nonlinear model. The active suspension control algorithm used in this paper includes the integral action of the suspension deflection in order to make zero the suspension deflection steady state and keep the vehicle chassis flat. Keeping the chassis flat reduces the vehicle load transfer and that is helpful for road holding and yaw rate tracking. The effects of the two controllers when they work together are analysed using various computer simulations with different steering wheel manoeuvres.

    2011-02-01

    A series of studies examined whether political participation can emerge from general patterns of indiscriminate activity. In the first two studies, general action tendencies were measured by combining national and state-level indicators of high activity (e.g., impulsiveness, pace of life, and physical activity) from international and U.S. data. This action-tendency index positively correlated with a measure of political participation that consisted of voting behaviors and participation in political demonstrations. The following two experimental studies indicated that participants exposed to action words (e.g., go, move) had stronger intentions to vote in an upcoming election and volunteered more time to make phone calls on behalf of a university policy than participants exposed to inaction words did (e.g., relax, stop). These studies suggest that political participation can be predicted from general tendencies toward activity present at the national and state levels, as well as from verbal prompts suggestive of activity.

    The aim of the present study was to report on factors associated with changes in disability after 5 years, with a focus on physical activity (PA) in community-dwelling older adults with generalized radiographic osteoarthritis (GROA). Assessment of GROA (hand, knee, hip) and disability (Health Assessment Questionnaire) in the Rotterdam Study (cohort RS-1, N = 7,983; with GROA, n = 821). A good outcome at follow-up was defined as improved or mild disability, and a poor outcome as worsened or severe disability. Factors potentially associated with outcome were demographics, joint complaints, other chronic health problems or limitations (body mass index, number of chronic conditions, cognition), and level of different types of PA. Some of these assessments were repeated in between 1997 and 1999 (RS-3), and between 2002 and 2004 (RS-4). A total of 309 older adults with GROA and valid measures on RS-3 and RS-4 showed mild to moderate disability, with minor increases over 5 years (follow-up N = 287 RS-3 to RS-4). PA levels decreased with increasing disability, especially in sport and walking. PA was univariately associated with a better outcome at follow-up but when adjusted for other factors (higher age, having knee pain and stiffness, and having more than two other chronic conditions) was associated with negative changes in general and lower limb disability, although not with upper limb disability. This was the first study to report that community-dwelling older adults with GROA show moderate levels of disability, and that reduced levels of disability are associated with higher levels of PA, but when adjusted for other confounders this association is lost. Further research is needed to study the complex relationships between PA and other determinants of disability. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available We decided to focus our research on two of the basic forms of ground squirrel s behaviour in the semi natural conditions of zoological gardens general activity and protective behavior. Our main goal was to perform a complex analysis of the ground squirrel s behaviour living in captivity and to compare the various categories of behaviour on a set timeline. We performed our research throughout the span of two years 2011 2012, during which we observed two separate ground squirrel colonies A, B. We took our compiled information and subjected these to a thorough statistical analysis and main tools of comparison. Based on a long term observation and analysis of the results, we were able to gather very detailed information about the two categories of the ground squirrel s behavior as well as the various periods on the timeline, which were worked into the ethogram of the ground squirrels living in captivity. The results from 2011 confirmed that the behavior of the ground squirrel bred in captivity both observed categories in the same way as was observed in the wild reaches two peaks with raised frequencies in manifestation of given behavior, mostly in the daily time periods, the first from 9am to 11am and the second from 2.30pm to 5pm. We also noted a change in 2012, when there was a reconstruction nearby the aviaries. These reconstructive activities influenced the behavior significant decrease of activity of the ground squirrels in the presence of the assigned workers approximately until 3pm, from which time also in connection with the lessening of the worker s presence the ground squirrels activity in their aviaries begun to rapidly rise, which held on until 5pm. The peak of protective behavior in 2012 has reached higher levels than the peak in 2011, which we attribute to their vigilance after the previous presence of people. Our results may serve as a basis for improvement of the life conditions of the ground squirrels bred in captivity as well as

    For over 3 weeks in October 2002, a series of sniper attacks in the Washington, DC, area left 10 people dead and 3 wounded. This study examined the relationship of distress associated with routine activities and perceived safety to psychological and behavioral responses. Participants were 1238 residents of the Washington, DC, metropolitan area (aged 18 to 90 years, mean=41.7 years) who completed an Internet survey including the Impact of Event Scale-Revised, Patient Health Questionnaire-9, and items pertaining to distress related to routine activities, perceived safety, and alcohol use. Data were collected at one time point approximately 3 weeks after the first sniper shooting and before apprehension of the suspects. Relationships of distress and perceived safety to post-traumatic stress, depressive symptoms, and increased alcohol use were examined by using linear and logistic regression analyses. Approximately 8% of the participants met the symptom criteria for probable post-traumatic stress disorder, 22% reported mild to severe depression, and 4% reported increased alcohol use during the attacks. Distress related to routine activities and perceived safety were associated with increased post-traumatic stress and depressive symptoms and alcohol use. Distress and perceived safety are associated with specific routine activities and both contribute to psychological and behavioral responses during a terrorist attack. These findings have implications for targeted information dissemination and risk communication by community leaders.

    In 2004, the International Atomic Energy Agency (IAEA) organized the International Project on Safety Assessment Driving Radioactive Waste Management Solutions (SADRWMS) to examine international approaches to safety assessment for predisposal management of radioactive waste. The initial outcome of the SADRWMS Project was achieved through the development of flowcharts which could be used to improve the mechanisms for applying safety assessment methodologies to predisposal management of radioactive waste. These flowcharts have since been incorporated into DS284 (General Safety Guide on the Safety Case and Safety Assessment for Predisposal Management of Radioactive Waste), and were also considered during the early development stages of the Safety Assessment Framework (SAFRAN) Tool. In 2009 the IAEA presented DS284 to the IAEA Waste Safety Standards Committee, during which it was proposed that the graded approach to safety case and safety assessment be illustrated through the development of Safety Reports for representative predisposal radioactive waste management facilities and activities. To oversee the development of these reports, it was agreed to establish the International Project on Complementary Safety Reports: Development and Application to Waste Management Facilities (CRAFT). The goal of the CRAFT project is to develop complementary reports by 2014, which the IAEA could then publish as IAEA Safety Reports. The present work describes how the DS284 methodology and SAFRAN Tool can be applied in the development and review of the safety case and safety assessment to a range of predisposal waste management facilities or activities within the Region.

    The use of intrapleural therapy with tissue plasminogen activator and DNase improves outcomes in patients with complicated pleural space infections. However, little data exists for the use of combination intrapleural therapy after the initial dosing period of six doses. We sought to describe the safety profile and outcomes of intrapleural therapy beyond this standard dosing. A retrospective review of patients receiving intrapleural therapy with tissue plasminogen activator and DNase was performed at two institutions. We identified 101 patients from January 2013 to August 2015 receiving intrapleural therapy for complicated pleural space infection. The extended use of intrapleural tissue plasminogen activator and DNase therapy beyond six doses was utilized in 20% (20/101) of patients. The mean number of doses in those undergoing extended dosing was 9.8 (range of 7–16). Within the population studied there appears to be no statistically significant increased risk of complications, need for surgical referral, or outcome differences when comparing those receiving standard or extended dosing intrapleural therapy. Future prospective study of intrapleural therapy as an alternative option for patients who fail initial pleural drainage and are unable to tolerate/accept a surgical intervention appears a potential area of study.

    Ever-increasing launch of small satellites demands an effective and efficient computer-aided analysis approach to shorten the ground test cycle and save the economic cost. However, the multiple influencing factors hamper the efficiency and accuracy of separation reliability assessment. In this study, a novel evaluation approach based on active subspace identification and response surface construction is established and verified. The formulation of small satellite separation is firstly derived, including equations of motion, separation and gravity forces, and quantity of interest. The active subspace reduces the dimension of uncertain inputs with minimum precision loss and a 4th degree multivariate polynomial regression (MPR) using cross validation is hand-coded for the propagation and error analysis. A common spring separation of small satellites is employed to demonstrate the accuracy and efficiency of the approach, which exhibits its potential use in widely existing needs of satellite separation analysis.

    safety and healthy working environment has received numerous research attention over the years. Majority of these researches seem to have been conducted in the construction industry, with little attention in the health sector. Nonetheless, there are couple of studies conducted in Africa that suggest pressure in hospitals. Therefore the aim of the study was to examine how pressure influence safety behavior in the hospitals. With reference to the relevance of safety behavior in primary health care delivery, there was the need for the study. Data was obtained from 422 public hospital employees. Respondents were assured that all information would be kept confidential to increase the response rate and acquire more accurate information. Collection of questionnaires from participants took four weeks (20 working days), after which the data was analyzed. The result of the study showed that work pressure correlated negatively with safety behavior. General safety climate significantly correlated positively with safety behavior and negatively with work pressure, although the effect size for the latter was smaller. Hierarchical regression analysis showed management commitment to safety to moderate the relationship between work pressure and safety behavior. When employees perceive safety communication, safety systems and training to be positive, they seem to comply with safety rules and procedures than voluntarily participate in safety activities.

    Full Text Available UNLABELLED: Mucosal antibodies harboring various antiviral activities may best protect mucosal surfaces against early HIV-1 entry at mucosal sites and they should be ideally induced by prophylactic HIV-1 vaccines for optimal prevention of sexually transmitted HIV-1. A phase I, double-blind, randomized, placebo-controlled trial was conducted in twenty-four healthy HIV-uninfected young women. The study objectives were to assess the safety, tolerability and immunogenicity of virosomes harboring surface HIV-1 gp41-derived P1 lipidated peptides (MYM-V101. Participants received placebo or MYM-V101 vaccine at 10 μg/dose or 50 μg/dose intramuscularly at week 0 and 8, and intranasally at week 16 and 24. MYM-V101 was safe and well-tolerated at both doses administered by the intramuscular and intranasal routes, with the majority of subjects remaining free of local and general symptoms. P1-specific serum IgGs and IgAs were induced in all high dose recipients after the first injection. After the last vaccination, vaginal and rectal P1-specific IgGs could be detected in all high dose recipients. Approximately 63% and 43% of the low and high dose recipients were respectively tested positive for vaginal P1-IgAs, while 29% of the subjects from the high dose group tested positive for rectal IgAs. Serum samples had total specific IgG and IgA antibody concentrations ≥ 0.4 μg/mL, while mucosal samples were usually below 0.01 μg/mL. Vaginal secretions from MYM-V101 vaccinated subjects were inhibiting HIV-1 transcytosis but had no detectable neutralizing activity. P1-specific Th1 responses could not be detected on PBMC. This study demonstrates the excellent safety and tolerability of MYM-V101, eliciting systemic and mucosal antibodies in the majority of subjects. Vaccine-induced mucosal anti-gp41 antibodies toward conserved gp41 motifs were harboring HIV-1 transcytosis inhibition activity and may contribute to reduce sexually-transmitted HIV-1. TRIAL

    2014-02-01

    Full Text Available This scientific opinion of EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety assessment of the active substances palladium metal (CAS No 7440-05-3, FCM No 993 and hydrogen gas (CAS No 1333-74-0, FCM No 1038, which are intended to be used as an oxygen scavenger in packages of foods and beverages at room temperature or below. The active article is designed as a gas permeable but liquid impermeable laminated pad, which is placed within a cap or closure or as an adhesive label on tray lids. The palladium metal is not in direct contact with the food being separated from it by different layers of passive materials. The specific migration of palladium metal into conventional food simulants was not detected at the limit of quantification of 0.6 µg/kg. Palladium was considered to be non genotoxic and of no toxicological concern under a low exposure level resulting from a concentration up to 50 µg/kg food in a previous evaluation (EFSA CEF Panel, 2012. Based on these previously drawn conclusions and given the intended conditions of use leading to non-detectable migration, the CEF Panel concluded that the active substances palladium and hydrogen do not raise a safety concern for the consumer when used as an oxygen scavenger in packages for foods and beverages at room temperatures or below. Palladium should not be in direct contact with food and should be incorporated in a passive structure impermeable to liquids which prevents the migration at detectable levels.

  1. Long-term outcome of patients with active ankylosing spondylitis with etanercept-sustained efficacy and safety after seven years

    2013-01-01

    Introduction Data from clinical studies on the long-term efficacy and safety of anti-tumor necrosis factor (TNF)-α therapy in patients with ankylosing spondylitis (AS) are scarce. This is the first report on continuous treatment with the TNFα fusion protein etanercept over seven years (y). Methods Overall, 26 patients with active AS were initially treated with etanercept 2 × 25 mg s.c./week with no concomitant disease modifying anti-rheumatic drugs (DMARDs) or steroids. The clinical response was assessed by standardized parameters. The primary outcome was the proportion of patients in the Spondyloarthritis International Society (ASAS) partial remission at seven years. AS disease activity scores (ASDAS) for status and improvement were compared to conventional outcome measures. Results Overall, 21/26 patients (81%) completed two years of treatment and 16/26 patients (62%) completed seven years. In the completer analysis, 31% patients were in ASAS partial remission at seven years, while 44% patients showed an ASDAS inactive disease status. Mean Bath AS activity index (BASDAI) scores, which were elevated at baseline (6.3 ± 0.9), showed constant improvement and remained low: 3.1 ± 2.5 at two years and 2.5 ± 2.2 at seven years, while ASDAS also improved (3.9 ± 0.7 at baseline, 1.8 ± 0.9 at two years, 1.6 ± 0.8 at seven years), all P <0.001. From the 10 dropouts, only 5 patients discontinued treatment due to adverse events. Patients who completed the study had lower baseline Bath AS function index (BASFI) scores vs. patients who discontinued. No other clinical parameter at baseline could predict any long-term outcome. Conclusions This study confirms the clinical efficacy and safety of etanercept in patients with active AS over seven years of continuous treatment. After seven years, more than half of the initially treated patients remained on anti-TNF therapy, and one-third were in partial remission.

    Background: Recombinant activated factor VII induces hemostasis in patients with coagulopathy disorders. AryoSeven™ as a safe Iranian Recombinant activated factor VII has been available on our market. This study was performed to establish the safety of AryoSeven on patients with coagulopathy disorder. Methods: This single-center, descriptive, cross sectional study was carried out in Thrombus and Homeostasis Research Center ValiAsr Hospital during 2013-2014. Fifty one patients with bleeding disorders who received at least one dose of Aryoseven were enrolled. Patients’ demographic data and adverse effect of drug and reaction related to Aryoseven or previous usage of Recombinant activated FVII were recorded in questionnaires. Finally data were analyzed to compare side effects of Aryoseven and other Recombinant activated FVII brands. Results: Aryoseven was prescribed for 51 Patients. Of all participants with mean age 57.18+21.38 yr, 31 cases were male and 26 subjects had past history of recombinant activated FVII usage. Glanzman was the most frequent disorder followed by congenital FVII deficiency, hemophilia with inhibitors, factor 5 deficiency, acquired hemophilia, hemophilia A with inhibitor, and hemophilia A or B with inhibitor. The majority of bleeding episodes had occurred in joints. Three patients (5.9%) complained about adverse effects of Aryoseven vs. 11.5 % about adverse effects of other brands. However this difference was not significant, statistically. Conclusion: Based on monitor patients closely for any adverse events, we concluded that Aryoseven administration under careful weighing of benefit versus potential harm may comparable with other counterpart drugs.

    2014-07-01

    Full Text Available This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety assessment of polyacrylic acid, sodium salt, crosslinked, FCM substance No 1015, which is intended to be used as a liquid absorber in the packaging of fresh or frozen foods such as meat, poultry, and seafood as well as fresh fruits and vegetables. Specific migration tests were not performed due to the high absorption of liquids by the substance. The Panel noted that if polyacrylic acid, sodium salt, crosslinked is used not in direct contact with food and placed in a pad under conditions where its absorption capacity is not exceeded, then no migration is to be expected and therefore no exposure from the consumption of the packed food is expected. The Panel also considered that non-crosslinked polymer and the crosslinkers do not raise a concern for genotoxicity. The CEF Panel concluded that the use of the substance polyacrylic acid, sodium salt, crosslinked, does not raise a safety concern when used in absorbent pads in the packaging of fresh or frozen foods. The absorbent pads must be used only under conditions in which the absorption capacity of the active substance is not exceeded and direct contact with food is excluded.

    One of the fundamental components so much for the sure operation, like in emergency cases or accident are the equipment s and instrumentation and control systems. The nuclear industry has had some accidents where the instrumentation and control have played and important part: a wrong design, instrumentation lack, faulty systems of safety, etc. At the present time the necessity to modernize the instrumentation and control in a nuclear power plant is before the challenge of finding innovative forms to improve the competitiveness and readiness, reducing operation costs without put ing in risk the safety and reliability of the nuclear power plant. Most of the nuclear power plants require actualizing their instrumentation and control systems, here the digital systems represent a great alternative, improving the performance and the safety, increasing the readiness and reducing the maintenance s. However they require of strict tests that allow assuring their application in critical systems. It is also necessary, the development of modernization programs that allow the programmed substitution of the systems without affecting the readiness of the nuclear power plants. During this whole modernization process will be necessary to put special attention in the cyber-safety because the attacks every time they are more elaborated. Therefore will be necessary to go toward the modernization of the instrumentation and control with the challenge of making without detriment some in the safety of the normal operation and with response reliability in emergency conditions or accident that which represents an effort that should not be postponed in the case of the nuclear power plant of Laguna Verde.

    Full Text Available This study assesses chronic disease or disease-related conditions as motivators of physical activity. It also compares these and other motivators of physical activity between Senior Games participants (SGPs and the general population. Analyses are based on an anonymous cross-sectional survey conducted among 666 SGPs and 177 individuals from the general population. SGPs experienced better general health and less obesity, diabetes, and depression, as well as an average of 14.7 more years of regular physical activity (p < .0001, 130.8 more minutes per week of aerobic activity (p < .0001, and 42.7 more minutes of anaerobic activity per week (p < .0001. Among those previously told they had diabetes, high blood pressure, high cholesterol, or depression, 74.2%, 72.2%, 70.4%, and 60.6%, respectively, said that it motivated them to increase their physical activity. Percentages were similar between SGPs and the general population. SGPs were more likely motivated to be physically active to improve physical and mental health in the present, to prevent physical and cognitive decline in the future, and to increase social opportunities. The Senior Games reinforces extrinsic motivators to positively influence intrinsic promoters such as skill development, satisfaction of learning, enjoyment, and fun.

    Lung cancer continues to be a difficult disease frequently diagnosed in late stages with a high mortality and symptom burden. In part because of frequent lung comorbidity, even lung cancer survivors often remain symptomatic and functionally limited. Though targeted therapy continues to increase treatment options for advanced-stage disease, symptom burden remains high with few therapeutic options. In the last several decades, exercise and physical activity have arisen as therapeutic options for obstructive lung disease and lung cancer. To date, exercise has been shown to reduce symptoms, increase exercise tolerance, improve quality of life, and potentially reduce length of stay and postoperative complications. Multiple small trials have been performed in perioperative non-small-cell lung cancer patients, although fewer studies are available for patients with advanced-stage disease. Despite the increased interest in this subject over the last few years, a validated exercise regimen has not been established for perioperative or advanced-stage disease. Clinicians underutilize exercise and pulmonary rehabilitation as a therapy, in part because of the lack of evidence-based consensus as to how and when to implement increasing physical activity. This review summarizes the existing evidence on exercise in lung cancer patients.

    Flavonoids are natural plant pigments, which possess high antioxidative and antiradical activities. However, their poor water solubility led to a limited bioavailability. To overcome this major hurdle, quercetin nanocrystals were produced implementing smartCrystals® technology. This process combines bead milling and subsequent high-pressure homogenization at relatively low pressure (300bar). To test the possibility to develop a dermal formulation from quercetin smartCrystals®, quercetin nanosuspensions were admixed to Lutrol® F127 and hydroxythylcellulose nonionic gels. The physicochemical properties (morphology, size and charge), saturation solubility, dissolution velocity and the antioxidant properties (DPPH assay) as well as the cellular interaction of the produced quercetin smartCrystals® were studied and compared to crude quercetin powder. Quercetin smartCrystals® showed a strong increase in the saturation solubility and the dissolution velocity (7.6 fold). SmartCrystals® loaded or not into gels proved to be physically stable over a period of three months at 25°C. Interestingly, in vitro DPPH assay confirmed the preservation of quercetin antioxidative properties after nanonization. In parallel, the nanocrystalline form did not display cellular toxicity, even at high concentration (50μg/ml), as assayed on an epithelial cell line (VERO cells). In addition, the nanocrystalline form confirmed a protective activity for VERO cells against hydrogen peroxide induced toxicity in vitro. This new formulation presents a promising approach to deliver quercetin efficiently to skin in well-tolerated formulations.

    Ethnopharmacological relevance Priva adhaerens (Forssk.) Chiov., a wildly growing plant, is reported in central Uganda to be an effective traditional remedy for diarrhea. The objective of this study was to provide a scientific basis for the ethnopharmacological utility of this plant whose aqueous leaf and shoot extract was evaluated for acute toxicity and antidiarrheal activity using a murine model. Materials and methods Acute toxicity of the aqueous leaf and shoot extract was assessed after determining the major phytochemicals present in the extract. The aqueous leaf and shoot extract was assayed against castor oil-induced diarrhea, transit time, and enteropooling, in comparison to loperamide, a standard drug. Results The oral LD50 value obtained for Priva adhaerens aqueous extract was greater than 5000 mg/kg in rats; the aqueous leaf and shoot extract possessed several important phytochemicals. Furthermore, the aqueous extract significantly, and dose-dependently, reduced frequency of stooling in castor oil-induced diarrhea, intestinal motility, and castor oil-induced enteropooling in rats. Conclusion This murine model shows that it is relatively safe to orally use the aqueous leaf and shoot extract of Priva adhaerens . The aqueous extract contains phytochemicals that are active for the treatment of diarrhea in a rat model. PMID:25304198

    Full Text Available This study was performed to evaluate the analgesic activity and the toxicity of ketorolac in normal and fractionated (1.5 Gy/day/4 days γ-irradiated animals. Determination of brain serotonin content and serum prostaglandin level were also undertaken. The analgesic activity was tested using formalin test, at three dose levels (15, 30 and 60 mg/kg after 1 and 7 days post radiation exposure. LD50 determinations and assessment of liver and kidney function tests were performed. Our results indicated marked analgesic effects on the early and late phases of nociception. Double treatment with ketorolac and irradiation increased brain serotonin content. The acute LD50 of ketorolac was decreased in irradiated animals as compared to the LD50 of normal animals. Double treatment with ketorolac and irradiation induced an elevation of gastric mucin content, urea and BUN levels on the 1st day post irradiation, whereas, albumin level was lowered and globulin level was elevated after 7 days post irradiation. Depending on this study the dose of ketorolac used for treating cancer patients addressed to radiotherapy should be reduced, however, this requires further clinical confirmation.

    This is the second of two volumes that collectively comprise the NASA System Safety Handbook. Volume 1 (NASASP-210-580) was prepared for the purpose of presenting the overall framework for System Safety and for providing the general concepts needed to implement the framework. Volume 2 provides guidance for implementing these concepts as an integral part of systems engineering and risk management. This guidance addresses the following functional areas: 1.The development of objectives that collectively define adequate safety for a system, and the safety requirements derived from these objectives that are levied on the system. 2.The conduct of system safety activities, performed to meet the safety requirements, with specific emphasis on the conduct of integrated safety analysis (ISA) as a fundamental means by which systems engineering and risk management decisions are risk-informed. 3.The development of a risk-informed safety case (RISC) at major milestone reviews to argue that the systems safety objectives are satisfied (and therefore that the system is adequately safe). 4.The evaluation of the RISC (including supporting evidence) using a defined set of evaluation criteria, to assess the veracity of the claims made therein in order to support risk acceptance decisions.

    Full Text Available Objective: To study the analgesic activity of ash of silver used in Indian system of medicine and to explore its safety. Materials and Methods: Albino mice of either sex (20-30 gm were used to investigate the role of ash of silver against noxious stimuli: thermal (Eddy′s hot plate and analgesiometer, mechanical (tail clip, and chemical (0.6% acetic acid induced writhing. An effort was made to find nature and site of action of ash of silver following naloxone pre-treatment. Maximum tolerated dose (MTD and lethal dosage 50 (LD50 were also studied along with toxicological aspects of ash of silver. Results: Test drug (ash of silver at a dose of 50 mg/kg p.o exhibited analgesic activity against thermal, mechanical, and chemical stimuli. Analgesic effects were compared with the standard drug, morphine, in thermal and mechanical noxious stimuli and to aspirin in chemical stimulus. Analgesic activity of the test drug was reduced following naloxone pre-treatment. MTD was found out to be greater than 1.5 g/kg p.o. LD50 was 2 g/kg p.o. Fraction of mice showed symptoms of argyria as explained by autopsy reports. Conclusion: Test drug exhibited moderate analgesic activity at 50 mg/kg p.o against all type of noxious stimuli, also suggesting a role of opioidergic system. The ash of silver was been found to be safe upto a dose of 1.5 g/kg p.o. in mice without any untoward toxicity. Further studies are required to explore the effect of ash of silver on pain mediators and excitatory neurotransmitters like glutamate, aspartate, or N-methyl-D-aspartic acid (NMDA.

    Fifteen consecutive children with ingested safety pins were evaluated retrospectively. Eight patients were males and seven were girls. The mean age of the patients was 5.4 years ranging from 7 months to 16 years. Two of 15 patients were mentally retarded Seven safety pins ingestion were noted by parents, three older children applied with safety pin swallowing. Three infants referred with hypersalivation and swallowing difficulty. One of two mentally retarded patients had recurrent aspiration pneumonia, the other had neck abscess. These patients' lesions were detected incidentally by thoracic X-ray. Nine safety pins were at the level of the cricopharyngeus, one at the level of the aortic arch and five at the esophagogastric junction. A right esophagoscopy was used for extraction of safety pins under general anesthesia and endotracheal intubation were used. Before esophagoscopy control plain X-ray was obtained for location of safety pin. Nine safety pins were extracted by esophagoscopy. Three safety pins spontaneously and three during anesthesia induction passed through the esophagus falling down the stomach. Five of these six safety pins were spontaneously extracted without complication. However one open safety pin lodged at the duodenum and laparotomy was required. In this article, etiology and management of safety pin ingestion in children are discussed.

    Safety culture has become a topic of increasing interest for industry and regulators as issues are raised on safety problems around the world. The keys to safety culture are organizational effectiveness, effective communications, organizational learning, and a culture that encourages the identification and resolution of safety issues. The necessity of a strong safety culture places an onus on all of us to continually question whether the safety measures already in place are sufficient, and are being applied. (author)

    2008-05-01

    Full Text Available Abstract Background Counselling in routine general practice to promote physical activity (PA is advocated, but inadequate evidence is available to support this intervention, and its sustainable implementation over time is difficult. Objectives To describe the characteristics of physically inactive adults visiting GPs and the factors associated with their willingness to change PA. Methods A cross-sectional analysis of 4317 Spanish people aged 20–80 years, selected by systematic sampling among those attending 56 public primary health care practices identified as inactive by their GPs in 2003. PA (7-day PAR, PA stage of change, health-related quality of life (SF-36, cardiovascular risk factors, and social and demographic characteristics were measured. Multivariate mixed effects ordinal logistic models were adjusted to identify factors associated with motivational readiness to change. Results At least 70% (95% CI: 67.6% to 72.8% of patients assessed by GPs did not achieve minimal PA recommendations. In addition, 85% (95% CI: 83% to 86.3% had at least an additional cardiovascular risk factor. Only 30% (95% CI: 25.8% to 33.5% were prepared for or attempting a change. A younger age; retirement or work at home; higher education and social class levels; obesity; and hypertension were associated with a higher motivational readiness to change (p Conclusion The overburden that would result from counselling such a high proportion of inactive primary care patients justifies a targeted strategy for PA promotion in family practice. Selection of a target population based on readiness to change, the combination of risk factors and socio-demographic characteristics of patients is suggested in order to prioritise promotion efforts.

    Full Text Available Dalia Jacob,1 Belén Marrón,2 Jay Ehrlich,1 Peter A Rutherford3 1Baxter Healthcare Corporation, Deerfield, IL, USA; 2Baxter Healthcare Corporation, Madrid, Spain; 3Baxter Healthcare SA, Zurich, Switzerland Abstract: Pharmacovigilance is instrumental in helping to ensure patient safety for both newly released drugs and those that are well established in the market. However, while pharmacovigilance procedures are strictly regulated in the clinical trial setting, post-marketing adverse event reporting is not well implemented or enforced. As such, the underreporting of adverse events, in relation to drugs that are on the market, is estimated to be in the region of 90%. The identification of drug safety issues in patients with complex diseases and extensive comorbidities is therefore particularly challenging. Dialysis patients – those with end-stage renal disease and often other comorbidities such as diabetes, hypertension, and cardiovascular disease – are a population with significant treatment challenges. Patients receive dialysis using complex medical devices (eg, a peritoneal dialysis home cycler and also receive a range of pharmaceutical agents as part of dialysis itself (eg, peritoneal dialysis solutions. Many of the pharmaceutical agents used to treat these patients have been developed in populations without these complications and, therefore, an extensive knowledge of potential problems and contraindications in the dialysis population is lacking. It is important that the nephrology community understands the concept of pharmacovigilance – the pharmacologic science relating to the detection, assessment, understanding, and prevention of adverse effects, particularly long-term and short-term side effects, of medicines. Health care professionals (HCPs and providers, pharmaceutical companies, global regulatory agencies, and the patients themselves all play unique and critical roles in this process.

    Full Text Available

    This scientific opinion of EFSA deals with the safety evaluation of the active substance iron (II modified bentonite (FCM Substance No 1003 intended to be incorporated in monolayer or multilayer packages or in sachets for absorbing oxygen from the food environment. All starting substances of the oxygen absorber have been evaluated and approved for use as additives in plastic food contact materials or as food additives. From a toxicological point of view, migration of iron (incorporated and aluminium (naturally present ions from bentonite is of interest. Iron can be estimated to migrate up to 4.5 mg/kg acidic food, which is well below the SML value of 48 mg/kg food set in Regulation EU No 10/2011 based on the PMTDI of 0.8 mg/kg bw established by the Joint FAO/WHO Expert Committee on Food Additives in 1983 and the SCF in 1990. The iron (II modified bentonite is intended and expected to be present in the final article as non-nanoform. However, the formation of nanoparticles due to exfoliation cannot be excluded if the substance is incorporated in unpolar polymers with compatibilisers or without such additives in polar polymers. Aluminium can be estimated to migrate up to 0.3 mg /kg acidic food. This value corresponds to 3.5 % of the TWI set in 2008 by the EFSA AFC Panel. Therefore, under the intended conditions of use, the oxygen absorber formulation was considered toxicologically acceptable. The CEF Panel concluded that the substance iron (II modified bentonite does not raise a safety concern for the consumer when used as oxygen absorber incorporated without compatibilisers in polyolefin layers of food packages at levels up to 15% w/w. The substance equally does not raise a safety concern when it is used in sachets, placed in the headspace of the packaging, that prevent the physical release of their contents into the food and are not in direct contact with liquid foods, exudates, or foods with external aqueous liquid phase.

    Pulmonary aspergillosis is frequently reported in parrots, falcons, and other birds held in captivity. Inhalation is the main route of infection for Aspergillus fumigatus, resulting in both acute and chronic disease conditions. Itraconazole (ITRA) is an antifungal commonly used in birds, but its administration requires repeated oral dosing, and the safety margin is narrow. To investigate the efficacy of inhaled ITRA, six groups of ten young quails (Coturnix japonica) were inoculated intratracheally with 5 × 10(6) spores (3 groups) or 5 × 10(7) spores (3 groups). Animals were exposed to nebulized ITRA nanosuspension as 10 % suspension or 4 % suspension, once daily for 30 min, starting 2 h after inoculation for 6 days. Control groups were exposed to nebulized saline for the same period of time. Survival and clinical scores were evaluated, and animals were subjected to gross pathology. In control animals, aspergillosis resulted in systemic disease without pulmonary or air sac granulomas. Animals died from multiple organ failure. Inhalation of 10 % ITRA nanosuspension blocked lethality and prevented disease-related symptoms in the quails exposed to the low dose of spores, while the disease course in quails inoculated with the high-spore dose was retarded. Inhalation of 4 % ITRA nanosuspension was less effective. Both inhalations were well tolerated, and gross pathology did not reveal signs of local toxicity. The data indicate that inhaled administration of 10 % ITRA nanosuspension is capable of alleviating an acute A. fumigatus infection in quails. A lower ITRA concentration may be only active in chronic pulmonary aspergillosis.

    We developed a semi-automated active monitoring system that uses sequential matched-cohort analyses to assess drug safety across a distributed network of longitudinal electronic healthcare data. In a retrospective analysis, we showed that the system would have identified cerivastatin-induced rhabdomyolysis. In this study, we evaluated whether the system would generate alerts for three drug-outcome pairs: rosuvastatin and rhabdomyolysis (known null association), rosuvastatin and diabetes mellitus, and telithromycin and hepatotoxicity (two examples for which alerting would be questionable). During >5 years of monitoring, rate differences (RDs) comparing rosuvastatin to atorvastatin were -0.1 cases of rhabdomyolysis per 1,000 person-years (95% CI, -0.4, 0.1) and -2.2 diabetes cases per 1,000 person-years (95% CI, -6.0, 1.6). The RD for hepatotoxicity comparing telithromycin to azithromycin was 0.3 cases per 1,000 person-years (95% CI, -0.5, 1.0). In a setting in which false positivity is a major concern, the system did not generate alerts for three drug-outcome pairs. PMID:22588606

  15. You've found a safety signal--now what?: regulatory implications of industry signal detection activities.

    Science.gov (United States)

    Kahn, Sidney N

    2007-01-01

    Signals detected by measuring disproportionality of drug-event combinations are only statistical indicators of possible real safety issues, and are not per se necessarily medically important. Nevertheless, once a signal is observed, sponsors are obligated by regulations and ethical considerations to determine whether it represents a new product-associated risk by additional analysis, validation and evaluation of its clinical relevance. Signal strength does not necessarily correlate with medical significance. Strong signals most often represent known, expected and/or medically trivial adverse reactions or confounding by treatment indication, common co-morbidities or other common concomitant treatments. Conversely, any product with reasonably extensive clinical use and reporting of suspected adverse reactions is likely to manifest many weak but clinically unimportant signals, creating significant background 'noise'. Since relatively rare, medically important adverse drug reactions are often likely to manifest as weak signals, sponsors face a potentially onerous burden of evaluating multiple signals in order to distinguish true, clinically important events of concern from spurious signals. This paper discusses the regulatory, clinical and potential legal liability issues that confront industry as a consequence of signal identification activities, including: current and anticipated regulatory requirements for detection, assessment and reporting; the reliability of the data used for signal generation; assessment of clinical relevance; organisational approaches and responses to observed signals; targeted clinical and scientific responses to observed signals; and potential regulatory, legal and commercial impact.

    Full Text Available Beet-sugar factory - is a large, well-equipped with modern technology, the company that operates in a continuous circuit. In the technological structure of a sugar factory there are three production divisions: beet processing department, juice purification house and grocery department. In the grocery department of a sugar factory dangerous and harmful factors may encounter while using equipment such as vacuum devices, centrifuges, and crystallizer tank, massecuite distributor, driers and classifiers sugar. The working area of the service of machinery may appear dangerous or harmful factors, which are divided into the following groups: physical, chemical, biological and physiological. To maintain microclimate parameters can be applied general ventilation, in which the replacement of the warm air to the cold going around the room volume. Heating in the grocery department in the production season is not carried out, since it is sufficient to heat generated by the equipment. In the grocery department uses natural and artificial lighting. In the sugar factory used the following measures to protect against vibration: perform detailed assembly, eliminate defects and looseness of individual parts; way to isolate the transmission of vibrations from the machine to the foundation apply vibration isolators. Widespread use of electrical installations in a sugar factory creates the risk of electric shock to persons. Causes of electrical shocks are often disadvantages of construction and installation of the equipment, its operation is wrong. During drying and transportation of sugar produced by static electricity. To remove the static electricity equipment grounded; also used the increase in humidity; air ionization. To reduce the consumption of fresh industrial water from reservoirs provides for the establishment of the system of working circuits cleaning and maximum reuse of industrial water.

    The clinical utility of fecal microbiota transplantation (FMT) in patients with ulcerative colitis (UC) is still controversial. We investigated the efficacy and safety of single FMT for patients with mild to moderately active UC in a Japanese population. Fifty-seven patients were evaluated for eligibility, and 16 patients were excluded. Forty-one patients with UC refractory to standard medical therapy were treated with single FMT by colonoscopic administration. Changes in the fecal microbiota were assessed by 16S ribosomal DNA based terminal restriction fragment length polymorphism analysis. At 8 weeks after FMT, no patient achieved clinical remission, and 11 of 41 patients (26.8 %) showed clinical response. The full Mayo score and the Mayo clinical score significantly decreased at week 8 [full Mayo score 5.5 ± 2.4 (mean ± standard deviation) at initiation and 4.6 ± 2.2 at week 8, P < 0.004; Mayo clinical score 4.0 ± 2.0 at initiation and 3.0 ± 1.9 at week 8, P < 0.001], but there were no statistically significant effects on the Mayo endoscopic score. No adverse events occurred after FMT or during the follow-up period of 8 weeks. The proportion of Bifidobacterium was significantly higher in the donor feces used for responders than in the donor feces used for nonresponders. The proportion of Lactobacillales and Clostridium cluster IV were significantly higher in the donor feces used for nonresponders. Single FMT by colonoscopy was performed safely in all patients, but sufficient clinical efficacy and microbial restoration were not confirmed in patients with mild to moderately active UC.

    OBJECTIVE. The aim of the study was to establish the dynamics of β-glucuronidase activity in subjects suffering from type 1 diabetes and chronic untreated generalized periodontitis, subjects suffering from chronic untreated generalized periodontitis only, and control subjects not suffering from generic diseases with healthy periodontal tissue. MATERIAL AND METHODS. The study involved 165 19-50-year-old subjects who were divided into three groups: healthy subjects (n=55), subjects with chronic untreated generalized periodontitis (n=55), and subjects with type 1 diabetes and chronic untreated generalized periodontitis (n=55). Neutrophilic leukocytes of peripheral venous blood were exposed to bacterial stimuli: opsonized zymosan, nonopsonized Staphylococcus aureus, and prodigiosan. The activity of β-glucuronidase was determined by the spectrofluorimetry method. RESULTS. The diagnostic value of changes in β-glucuronidase activity of neutrophilic leukocytes markedly increased in all study groups after stimulation of neutrophilic leukocytes by opsonized zymosan, nonopsonized Staphylococcus aureus, and prodigiosan as compared to control media not exposed to any stimulus (Pperiodontal pathology markers and the activity of β-glucuronidase of neutrophilic leukocytes in incubated media in patients with type 1 diabetes mellitus and periodontitis was found under the effect of nonopsonized Staphylococcus aureus. CONCLUSIONS. If periodontal impairment is severe, diabetes mellitus possibly causes a faster destruction of the periodontal tissue and presents a higher risk of periodontitis for patients with diabetes.

    Brown, Ian

    2000-07-01

    This paper reports on a study of the level and type of activity used to involve the public in general practice in a city district in the north of England. The association of these activities with features of the general practice organisation and environment were studied. Service providers' perceptions of obstacles were also studied. Data were collected in a survey of all general practice organisations in the district using a postal questionnaire completed by a practice manager. Interviews were conducted with health service managers responsible for primary care development in the district. The study showed that the district had a good track record for innovation in primary care development and in giving emphasis to developing public involvement. However, it also showed that it was difficult to translate policy rhetoric into practical initiatives at the general practice level without evidence of models of best practice, and with limited resources. The survey had a high response of over 84%. It showed that levels of activity were low across the district and only a small minority of general practice teams had undertaken a range of activities to involve the public. The socio-economic environment did not appear to be a factor, but small practices (one or two partners and/or practice population under 3000) were much less likely to develop activities. Pressures of existing workload, lack of resources and public apathy were given as among the main obstacles by survey respondents. The study indicates the challenges faced by Primary Care Groups in developing strands of public involvement. Primary care teams need a clear strategic framework, models of best practice, and adequate resources to manage, change and develop initiatives.

    Evaluation of safety is a critical component of drug review at the US Food and Drug Administration (FDA). Statisticians are playing an increasingly visible role in quantitative safety evaluation and regulatory decision-making. This article reviews the history and the recent events relating to quantitative drug safety evaluation at the FDA. The article then focuses on five active areas of quantitative drug safety evaluation and the role Division of Biometrics VII (DBVII) plays in these areas, namely meta-analysis for safety evaluation, large safety outcome trials, post-marketing requirements (PMRs), the Sentinel Initiative, and the evaluation of risk from extended/long-acting opioids. This article will focus chiefly on developments related to quantitative drug safety evaluation and not on the many additional developments in drug safety in general.

    By using the ILSI network in Asia, we are holding a session focused on food safety programs in several Asian areas. In view of the external environment, it is expected to impact the global food system in the near future, including the rapid increase in food demand and in public health services due to population growth, as well as the threats to biosecurity and food safety due to the rapid globalization of the food trade. Facilitating effective information sharing holds promise for the activation of the food industry. At this session, Prof. Hwang shares the current situation of Food Safety and Sanitation Regulations in Taiwan. Dr. Liu provides a talk on the role of risk assessment in food regulatory control focused on aluminum-containing food additives in China. After the JECFA evaluation of aluminum-containing food additives in 2011, each country has carried out risk assessment based on dietary intake surveys. Ms. Chan reports on the activities of a working group on Food Standards Harmonization in ASEAN. She also explains that the ILSI Southeast Asia Region has actively supported the various ASEAN Working Groups in utilizing science to harmonize food standards. Prof. Park provides current research activities in Korea focused on the effect of climate change on food safety. Climate change is generally seen as having a negative impact on food security, particularly in developing countries. We use these four presentations as a springboard to vigorous discussion on issues related to Food Safety in Asia.

    Full Text Available Objective. This cross sectional study aims to determine the effects of gender and parental perception of safety at school on children’s physical activity (PA levels. Materials and methods. Parents of school aged Mexican children residing in Guadalajara, Mexico City, and Puerto Vallarta, completed surveys about their children’s PA measures. The physical activity indicators were evaluated using linear and logistical regression models. Results. Analysis did not indicate that gender moderated the relationship between parental perception of safety and PA measures, but significant gender issues exist with girls participating less than boys in the three measures of PA in this study (p<0.001. Conclusion. Results suggest the need for additional interventions promoting physical activity in girls in Mexico.

    The activation energy to reaction is a key quantity that controls catalytic activity. Having used ab inito calculations to determine an extensive and broad ranging set of activation energies and enthalpy changes for surface-catalyzed reactions, we show that linear relationships exist between dissociation activation energies and enthalpy changes. Known in the literature as empirical Brønsted-Evans-Polanyi (BEP) relationships, we identify and discuss the physical origin of their presence in heterogeneous catalysis. The key implication is that merely from knowledge of adsorption energies the barriers to catalytic elementary reaction steps can be estimated.

    2014-01-01

    Full Text Available Background: Generalized vitiligo is a disease with unpredictable bursts of activity, goal of treatment during the active phase being to stabilize the lesions. This emphasizes the need for a prospective marker for monitoring disease activity to help decide the duration of therapy. Aims and Objectives: In the present study, we examined whether reactive oxygen species (ROS generated in erythrocytes can be translated into a marker of activity in vitiligo. Materials and Methods: Level of intracellular ROS was measured flow cytometrically in erythrocytes from venous blood of 21 patients with generalized vitiligo and 21 healthy volunteers using the probe dichlorodihydrofluorescein diacetate. Results: The levels of ROS differed significantly between patients and healthy controls, as well as between active versus stable disease groups. In the active disease group, ROS levels were significantly lower in those being treated with systemic steroids than those that were not. ROS levels poorly correlated with disease duration or body surface area involved. Conclusion: A long-term study based on these findings can be conducted to further validate the potential role of ROS in monitoring disease activity vitiligo.

    Full Text Available Food safety is an important topic as large number of consumers has become victim of consuming adulterated foods. As the food safety laws, administration and inspection in Bangladesh do not include monitoring the chain of production and comply the recommendation by Codex Alimentarius Commission (CAC, Sanitary and Phytosanitary (SPS Agreement, and Hazard Analysis Critical Control Point (HACCP System, the government is encouraging the private sector to put the food processing and marketing into the context of standard, cost effectiveness, public health issues and global trade. Recommendations came up for strengthening collaboration between Ministries and stakeholders. Since the public health service cannot combat alone the complex situation, the governmental agencies and academic institutions must work together to delineate many of the problems in food safety, consumers protection and zoonoses. In this paper the profiling force linking safety and quality of foods of animal origin in Bangladesh is highlighted.

    One challenge of the complete active space self-consistent field (CASSCF) program is to solve the transition metal complexes which are typically medium or large-size molecular systems with large active space. We present an AO-driven second order CASSCF solver to efficiently handle systems which have a large number of AO functions and many active orbitals. This solver allows user to replace the active space Full CI solver with any multiconfigurational solver without breaking the quadratic convergence feature. We demonstrate the capability of the CASSCF solver with the study of Fe(ii)-porphine ground state using DMRG-CASSCF method for 22 electrons in 27 active orbitals and 3000 basis functions.

    Doron, Shira; Snydman, David R

    2015-05-15

    Probiotics have been used safely for years. Safety outcomes are inconsistently reported in published clinical trials. In 2011, a report released by the Agency for Healthcare Research and Quality concluded that, although the existing probiotic clinical trials reveal no evidence of increased risk, "the current literature is not well equipped to answer questions on the safety of probiotics in intervention studies with confidence." Critics point out that the preponderance of evidence, including the long history of safe probiotic use as well as data from clinical trials, and animal and in vitro studies all support the assumption that probiotics are generally safe for most populations. Theoretical risks have been described in case reports, clinical trial results and experimental models, include systemic infections, deleterious metabolic activities, excessive immune stimulation in susceptible individuals, gene transfer and gastrointestinal side effects. More research is needed to properly describe the incidence and severity of adverse events related to probiotics.

    Accurately predicting the occupant kinematics is critical to better understand the injury mechanisms during an automotive crash event. The objectives of this study were to develop and validate a finite element (FE) model of the human body integrated with an active muscle model called Total HUman Model for Safety (THUMS) version 5, which has the body size of the 50th percentile American adult male (AM50). This model is characterized by being able to generate a force owing to muscle tone and to predict the occupant response during an automotive crash event. Deformable materials were assigned to all body parts of THUMS model in order to evaluate the injury probabilities. Each muscle was modeled as a Hill-type muscle model with 800 muscle-tendon compartments of 1D truss and seatbelt elements covering whole joints in the neck, thorax, lumbar region, and upper and lower extremities. THUMS was validated against 36 series of post-mortem human surrogate (PMHS) and volunteer tests on frontal, lateral, and rear impacts. The muscle architectural and kinetic properties for the hip, knee, shoulder, and elbow joints were validated in terms of the moment arms and maximum isometric joint torques over a wide range of joint angles. The muscular moment arms and maximum joint torques estimated from THUMS occupant model with 1D muscles agreed with the experimental data for a wide range of joint angles. Therefore, this model has the potential to predict the occupant kinematics and injury outcomes considering appropriate human body motions associated with various human body postures, such as sitting or standing.

    Full Text Available Abstract Background Safety activities have been initiated at many hospitals in Taiwan, but little is known about the safety culture at these hospitals. The aims of this study were to verify a safety culture survey instrument in Chinese and to assess hospital safety culture in Taiwan. Methods The Taiwan Patient Safety Culture Survey was conducted in 2008, using the adapted Safety Attitude Questionnaire in Chinese (SAQ-C. Hospitals and their healthcare workers participated in the survey on a voluntary basis. The psychometric properties of the five SAQ-C dimensions were examined, including teamwork climate, safety climate, job satisfaction, perception of management, and working conditions. Additional safety measures were asked to assess healthcare workers' attitudes toward their collaboration with nurses, physicians, and pharmacists, respectively, and perceptions of hospitals' encouragement of safety reporting, safety training, and delivery delays due to communication breakdowns in clinical areas. The associations between the respondents' attitudes to each SAQ-C dimension and safety measures were analyzed by generalized estimating equations, adjusting for the clustering effects at hospital levels. Results A total of 45,242 valid questionnaires were returned from 200 hospitals with a mean response rate of 69.4%. The Cronbach's alpha was 0.792 for teamwork climate, 0.816 for safety climate, 0.912 for job satisfaction, 0.874 for perception of management, and 0.785 for working conditions. Confirmatory factor analyses demonstrated a good model fit for each dimension and the entire construct. The percentage of hospital healthcare workers holding positive attitude was 48.9% for teamwork climate, 45.2% for perception of management, 42.1% for job satisfaction, 37.2% for safety climate, and 31.8% for working conditions.

    Safety Pharmacology is a rapidly developing discipline that uses the basic principles of pharmacology in a regulatory-driven process to generate data to inform risk/benefit assessment. The aim of Safety Pharmacology is to characterize the pharmacodynamic/pharmacokinetic (PK/PD) relationship of a drug's adverse effects using continuously evolving methodology. Unlike toxicology, Safety Pharmacology includes within its remit a regulatory requirement to predict the risk of rare lethal events. This gives Safety Pharmacology its unique character. The key issues for Safety Pharmacology are detection of an adverse effect liability, projection of the data into safety margin calculation and finally clinical safety monitoring. This article sets out to explain the drivers for Safety Pharmacology so that the wider pharmacology community is better placed to understand the discipline. It concludes with a summary of principles that may help inform future resolution of unmet needs (especially establishing model validation for accurate risk assessment). Subsequent articles in this issue of the journal address specific aspects of Safety Pharmacology to explore the issues of model choice, the burden of proof and to highlight areas of intensive activity (such as testing for drug-induced rare event liability, and the challenge of testing the safety of so-called biologics (antibodies, gene therapy and so on.).

    Full Text Available This scientific opinion of CEF Panel deals with the risk assessment of polyacrylic acid, sodium salt crosslinked, FCM substance No 1015, which is intended to be used as liquid absorber in the packaging of fresh or frozen meat, poultry, and fish as well as fresh fruits and vegetables. Specific migration tests were not performed due to the high absorption of liquids by the substance. The Panel noted that if polyacrylic acid, sodium salt, crosslinked is used not in direct contact with food placed in a pad under conditions where its absorption capacity is not exceeded, then no migration is to be expected and therefore no exposure to the substance from the consumption of the packed food is expected. The CEF Panel concluded that the use of the substance polyacrylic acid, sodium salt, crosslinked does not raise a safety concern when used in absorbent pads in the packaging of fresh or frozen meat, poultry, and fish as well as fresh fruits and vegetables. The absorbent pads must be used only under conditions in which the absorption capacity of the active substance is not exceeded and direct contact with food is excluded.

    Full Text Available Background: Regular and daily physical activity during childhood and at school is one of the important part of requirements of normal growth, development and well-being. To achieve physical activity promotion among school child aged population recess as outside of class time efforts is scheduled and allows students to engage in physical and social activities. The purpose of the present study was to assess recess activities as well as status of physical activities among a sample of Iranian students at the pri¬mary schools.Methods: This cross-sectional study was performed in four randomly se¬lected schools from a list of 26 elementary schools in March, 2012 in the city of Shahindej, located in North-west of Iran. Participants were 439 (10–12 years elementary schools’. Physical activity level by self-reporting, mental health using the parent-completed Child Health Questionnaire, and happiness was assessed using a Persian translated version of the Subjective Happiness Scale. Hierarchical logistic regression analysis was applied in two steps using the enter method to analyze data in the SPSS version 17.Results: Backward logistic regression analysis showed that gender of the parent who answered the study questions, father’s education, educational grade of children, BMI, physical function, physical health, health status of the children and family function were significantly related to the children’s physical activity level.Conclusion: Promoting parents’ awareness and schools’ staff about im¬portance of physical activities especially in recess times must be an impor¬tant part of school and community mental health promotion programs.

    Cyclic Ru-phenolates were synthesized, and these compounds were used as olefin metathesis catalysts. Investigation of their catalytic activity pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne and cross-metathesis (CM) reactions, including butenolysis, with good results. Importantly, these latent catalysts are soluble in neat dicyclopentadiene (DCPD) and show good applicability in ring-opening metathesis polymeriyation (ROMP) of this monomer.

    In its usual form activated complex theory assumes a quasi-equilibrium between reactants and activated complex, a separable reaction coordinate, a Cartesian reaction coordinate, and an absence of interaction of rotation with internal motion in the complex. In the present paper a rate expression is derived without introducing the Cartesian assumption. The expression bears a formal resemblance to the usual one and reduces to it when the added assumptions of the latter are introduced.

    With decreasing budgets and increasing pressure on completing cleanup missions as quickly, safely and cost-effectively as possible, there is significant benefit to be gained from collaboration and joint efforts between organizations facing similar issues. With this in mind, the US Department of Energy (DOE) and the UK Nuclear Decommissioning Authority (NDA) have formally agreed to share information on lessons learned on the development and application of new technologies and approaches to improve the safety, cost effectiveness and schedule of the cleanup legacy wastes. To facilitate information exchange a range of tools and methodologies were established. These included tacit knowledge exchange through facilitated meetings, conference calls and Site visits as well as explicit knowledge exchange through document sharing and newsletters. A DOE web-based portal has been established to capture these exchanges and add to them via discussion boards. The information exchange is operating at the Government-to-Government strategic level as well as at the Site Contractor level to address both technical and managerial topic areas. This effort has resulted in opening a dialogue and building working relationships. In some areas joint programs of work have been initiated thus saving resource and enabling the parties to leverage off one another activities. The potential benefits of high quality information exchange are significant, ranging from cost avoidance through identification of an approach to a problem that has been proven elsewhere to cost sharing and joint development of a new technology to address a common problem. The benefits in outcomes significantly outweigh the costs of the process. The applicability of the tools and methods along with the lessons learned regarding some key issues is of use to any organization that wants to improve value for money. In the waste management marketplace, there are a multitude of challenges being addressed by multiple organizations and
