A Decision Fusion Framework for Treatment Recommendation Systems.
Mei, Jing; Liu, Haifeng; Li, Xiang; Xie, Guotong; Yu, Yiqin
2015-01-01
Treatment recommendation is a nontrivial task--it requires not only domain knowledge from evidence-based medicine, but also data insights from descriptive, predictive and prescriptive analysis. A single treatment recommendation system is usually trained or modeled with a limited (size or quality) source. This paper proposes a decision fusion framework, combining both knowledge-driven and data-driven decision engines for treatment recommendation. End users (e.g. using the clinician workstation or mobile apps) could have a comprehensive view of various engines' opinions, as well as the final decision after fusion. For implementation, we leverage several well-known fusion algorithms, such as decision templates and meta classifiers (of logistic and SVM, etc.). Using an outcome-driven evaluation metric, we compare the fusion engine with base engines, and our experimental results show that decision fusion is a promising way towards a more valuable treatment recommendation.

Many people spend lengthy periods each day in enclosed vehicles in Hong Kong. However, comparably limited data is available about in-cabin air quality in air-conditioned private vehicles, and the car usage that may affect the air quality. Fifty-one vehicles were tested for particulate matter (PM 0.3 and PM 2.5 ), total volatile organic compounds (TVOCs), carbon monoxide (CO), carbon dioxide (CO₂), airborne bacteria, and fungi levels during their routine travel journey. Ten of these vehicles were further examined for PM 0.3 , PM 2.5 , TVOCs, CO, and CO₂ during engine idling. In general, during driving PM 2.5 levels in-cabin reduced overtime, but not PM 0.3 . For TVOCs, 24% vehicles exceeded the recommended Indoor Air Quality (IAQ) level in offices and public places set by the Hong Kong Environmental Protection Department. The total volatile organic compounds (TVOC) concentration positively correlated with the age of the vehicle. Carbon monoxide (CO) levels in all of the vehicles were lower than the IAQ recommendation, while 96% vehicles exceeded the recommended CO₂ level of 1000 ppmv; 16% vehicles >5000 ppmv. Microbial counts were relatively low. TVOCs levels at idle engine were higher than that during driving. Although the time we spend in vehicles is short, the potential exposure to high levels of pollutants should not be overlooked.

Searching the Internet for information on prostate cancer screening: an assessment of quality.
Ilic, Dragan; Risbridger, Gail; Green, Sally
2004-07-01
To identify how on-line information relating to prostate cancer screening (PCS) is best sourced, whether through general, medical, or meta-search engines, and to assess the quality of that information. Websites providing information about PCS were searched across 15 search engines representing three distinct types: general, medical, and meta-search engines. The quality of on-line information was assessed using the DISCERN quality assessment tool. Quality performance characteristics were analyzed by performing Mann-Whitney U tests. Search engine efficiency was measured by each search query as a percentage of the relevant websites included for analysis from the total returned and analyzed by performing Kruskal-Wallis analysis of variance. Of 6690 websites reviewed, 84 unique websites were identified as providing information relevant to PCS. General and meta-search engines were significantly more efficient at retrieving relevant information on PCS compared with medical search engines. The quality of information was variable, with most of a poor standard. Websites that provided referral links to other resources and a citation of evidence provided a significantly better quality of information. In contrast, websites offering a direct service were more likely to provide a significantly poorer quality of information. The current lack of a clear consensus on guidelines and recommendation in published data is also reflected by the variable quality of information found on-line. Specialized medical search engines were no more likely to retrieve relevant, high-quality information than general or meta-search engines.

HVAC--the importance of clean intake section and dry air filter in cold climate.
Hanssen, S O
2004-01-01
HVAC systems, if properly designed, installed, operated and maintained, will improve thermal conditions and air quality indoors. However, the success strongly depends on the design of the system and the quality of the components we use in our HVAC installations. Regrettably, several investigations have revealed that many HVAC installations have a lot of operational and maintenance problems, especially related to moisture, rain and snow entrainment. In short, it seems that too little attention is placed on the design of the intake section, despite the fact that there exists a large number of national and international guidelines and recommendations. This is a serious problem because the air intake is the initial component of the ventilation plant and as such the first line of defense against debris and other outdoor air pollutants. Unfortunately, the design is often an argued compromise between the architect, the civil engineer and the HVAC engineer. In the future, the technical, hygienic and microbiological feature of air intakes must be better ensured in order to avoid the air intake becoming a risk component as regards contamination and indoor air quality. Further, it seems that the magnitude of the problem is not well known, or recognized, by the building designers, engineers and professionals involved in the construction and operation of buildings. This fact needs to be addressed more seriously, because obviously there is a big difference between the idealistic architectonic design, engineering intentions and the real life situation. Several practical recommendations for design and operation of HVAC systems are presented. Following the recommendations will result in less pollution from the HVAC-system and increased indoor environmental quality.

Accessibility, nature and quality of health information on the Internet: a survey on osteoarthritis.
Maloney, S; Ilic, D; Green, S
2005-03-01
This study aims to determine the quality and validity of information available on the Internet about osteoarthritis and to investigate the best way of sourcing this information. Keywords relevant to osteoarthritis were searched across 15 search engines representing medical, general and meta-search engines. Search engine efficiency was defined as the percentage of unique and relevant websites from all websites returned by each search engine. The quality of relevant information was appraised using the DISCERN tool and the concordance of the information offered by the website with the available evidence about osteoarthritis determined. A total of 3443 websites were retrieved, of which 344 were identified as unique and providing information relevant to osteoarthritis. The overall quality of website information was poor. There was no significant difference between types of search engine in sourcing relevant information; however, the information retrieved from medical search engines was of a higher quality. Fewer than a third of the websites identified as offering relevant information cited evidence to support their recommendations. Although the overall quality of website information about osteoarthritis was poor, medical search engines may provide consumers with the opportunity to source high-quality health information on the Internet. In the era of evidence-based medicine, one of the main obstacles to the Internet reaching its potential as a medical resource is the failure of websites to incorporate and attribute evidence-based information.

Los Alamos National Laboratory (LANL) uses Capability Reviews to assess the quality and institutional integration of science, technology and engineering (STE) and to advise Laboratory Management on the current and future health of LANL STE. The capabilities are deliberately chosen to be crosscutting over the Laboratory and therefore will include experimental, theoretical and simulation disciplines from multiple line organizations. Capability Reviews are designed to provide a more holistic view of the STE quality, integration to achieve mission requirements, and mission relevance. The scope of these capabilities necessitate that there will be significant overlap in technical areas covered by capability reviewsmore » (e.g., materials research and weapons science and engineering). In addition, LANL staff may be reviewed in different capability reviews because of their varied assignments and expertise. The principal product of the Capability Review is the report that includes the review committee's assessments, recommendations, and recommendations for STE.« less

Investigators aimed to assess online information describing uterine artery embolization (UAE) to examine the quality and readability of websites patients are accessing. A list of applicable, commonly used searchable terms was generated, including "Uterine Artery Embolization," "Fibroid Embolization," "Uterine Fibroid Embolization," and "Uterine Artery Embolisation." Each possible term was assessed across the five most-used English language search engines to determine the most commonly used term. The most common term was then investigated across each search engine, with the first 25 pages returned by each engine included for analysis. Duplicate pages, nontext content such as video or audio, and pages behind paywalls were excluded. Pages were analyzed for quality and readability using validated tools including DISCERN score, JAMA Benchmark Criteria, HONcode Certification, Flesch Reading Ease Score, Flesch-Kincaid Grade Level, and Gunning-Fog Index. Secondary features such as age, rank, author, and publisher were recorded. The most common applicable term was "Uterine Artery Embolization" (492,900 results). Mean DISCERN quality of information provided by UAE websites is "fair"; however, it has declined since comparative 2012 studies. Adherence to JAMA Benchmark Criteria has reduced to 6.7%. UAE website readability remains more difficult than the World Health Organization-recommended 7-8th grade reading levels. HONcode-certified websites (35.6%) demonstrated significantly higher quality than noncertified websites. Quality of online UAE information remains "fair." Adherence to JAMA benchmark criteria is poor. Readability is above recommended 7-8th grade levels. HONcode certification was predictive of higher website quality, a useful guide to patients requesting additional information. Copyright © 2018 The Association of University Radiologists.

Collection and analysis of spacecraft cabin air samples are necessary to assess the cabin air quality with respect to crew health. Both toxicology and engineering disciplines work together to achieve an acceptably clean cabin atmosphere. Toxicology is concerned with limiting the risk to crew health from chemical sources, setting exposure limits, and analyzing air samples to determine how well these limits are met. Engineering provides the means for minimizing the contribution of the various contaminant generating sources by providing active contamination control equipment on board spacecraft and adhering to a rigorous material selection and control program during the design and construction of the spacecraft. A review of the rationale and objectives for sampling spacecraft cabin atmospheres is provided. The presently-available sampling equipment and methods are reviewed along with the analytical chemistry methods employed to determine trace contaminant concentrations. These methods are compared and assessed with respect to actual cabin air quality monitoring needs. Recommendations are presented with respect to the basic sampling program necessary to ensure an acceptably clean spacecraft cabin atmosphere. Also, rationale and recommendations for expanding the scope of the basic monitoring program are discussed.

Searches for health information are among the most common reasons that consumers use the Internet. Both consumers and quality experts have raised concerns about the quality of information on the Web and the ability of consumers to find accurate information that meets their needs. To produce a national stakeholder-driven agenda for research, technical improvements, and education that will improve the results of consumer searches for health information on the Internet. URAC, a national accreditation organization, and Consumer WebWatch (CWW), a project of Consumers Union (a consumer advocacy organization), conducted a review of factors influencing the results of online health searches. The organizations convened two stakeholder groups of consumers, quality experts, search engine experts, researchers, health-care providers, informatics specialists, and others. Meeting participants reviewed existing information and developed recommendations for improving the results of online consumer searches for health information. Participants were not asked to vote on or endorse the recommendations. Our working definition of a quality Web site was one that contained accurate, reliable, and complete information. The Internet has greatly improved access to health information for consumers. There is great variation in how consumers seek information via the Internet, and in how successful they are in searching for health information. Further, there is variation among Web sites, both in quality and accessibility. Many Web site features affect the capability of search engines to find and index them. Research is needed to define quality elements of Web sites that could be retrieved by search engines and understand how to meet the needs of different types of searchers. Technological research should seek to develop more sophisticated approaches for tagging information, and to develop searches that "learn" from consumer behavior. Finally, education initiatives are needed to help consumers search more effectively and to help them critically evaluate the information they find.

This paper recommends how authors of statistical studies can communicate to general audiences fully, clearly, and comfortably. The studies may use statistical methods to explore issues in science, engineering, and society or they may address issues in statistics specifically. In either case, readers without explicit statistical training should have no problem understanding the issues, the methods, or the results at a non-technical level. The arguments for those results should be clear, logical, and persuasive. This paper also provides advice for editors of general journals on selecting high quality statistical articles without the need for exceptional work or expense. Finally, readers are also advised to watch out for some common errors or misuses of statistics that can be detected without a technical statistical background.

Preoperative fasting is important to avoid morbidity and surgery delays, yet recommendations available on the Internet may be inaccurate. Our objectives were to describe the characteristics and recommendations of Internet resources on preoperative fasting and assess the quality and readability of these websites. We searched the Internet for common search terms on preoperative fasting using Google® search engines from 4 English-speaking countries (Canada, the United States, Australia, and the United Kingdom). We screened the first 30 websites from each search and extracted data from unique websites that provided recommendations on preoperative fasting. Website quality was assessed using validated tools (JAMA Benchmark criteria, DISCERN score, and Health on the Net Foundation code [HONcode] certification). Readability was scored using the Flesch Reading Ease score and Flesch-Kincaid Grade Level. A total of 87 websites were included in the analysis. A total of 48 websites (55%) provided at least 1 recommendation that contradicted established guidelines. Websites from health care institutions were most likely to make inaccurate recommendations (61%). Only 17% of websites encouraged preoperative hydration. Quality and readability were poor, with a median JAMA Benchmark score of 1 (interquartile range 0-3), mean DISCERN score 39.8 (SD 12.5), mean reading ease score 49 (SD 15), and mean grade level of 10.6 (SD 2.7). HONcode certification was infrequent (10%). Anesthesia society websites and scientific articles had higher DISCERN scores but worse readability compared with websites from health care institutions. Online fasting recommendations are frequently inconsistent with current guidelines, particularly among health care institution websites. The poor quality and readability of Internet resources on preoperative fasting may confuse patients.

The proposed conversion of predominant Air Force fuel usage from JP-4 to JP-8 has created the need to examine the dependence of engine pollutant emission on fuel type. Available data concerning the effect of fuel type on emissions has been reviewed. T56 single combustor testing has been undertaken to determine JP-4/JP-8 emission variations over a wide range of simulated engine cycle operating conditions at idle. In addition, a J85-5 engine was tested using JP-4 and JP-8. Results of the previous and new data collectively led to the following conclusions regarding conversion to JP-8: (a) HC and CO emission changes willmore » depend upon individual combustor design features, (b) no change to NOx emission will occur, and (c) an increase in smoke/particulate emissions will result. It is recommended that these findings be incorporated into air quality analytical models to define the overall impact of the proposed conversion. Further, it is recommended that combustor analytical models be employed to attempt prediction of the results described herein. Should these models be successful, analytical prediction of JP-8 emissions from other Air Force engine models may be substituted for more combustor rig or engine testing. (auth)« less

The internet is a major source for health information. An increasing number of people, including patients with insomnia, search for remedies online; however, little is known about the quality of such information. This study aimed to evaluate the quality and readability of insomnia-related online information. Google was used as the search engine, and the top websites on insomnia that met the inclusion criteria were evaluated for quality and readability. The analyzed websites belonged to nonprofit, commercial, or academic organizations and institutions such as hospitals and universities. Insomnia-related websites typically included definitions (85%), causes and risk factors (100%), symptoms (95%), and treatment options (90%). Cognitive behavioral therapy for insomnia (CBT-I) was the most commonly recommended approach for insomnia treatment, and sleep drugs are frequently mentioned. The overall quality of the websites on insomnia is moderate, but all the content exceeded the recommended reading ease levels. Concerns that must be addressed to increase the quality and trustworthiness of online health information include sharing metadata, such as authorship, time of creation and last update, and conflicts of interest; providing evidence for reliability; and increasing the readability for a layman audience.

A rotordynamic analysis of the T55-L-11C engine was used to evaluate the balancing needs of the power turbine and to optimize the balancing procedure. As a result, recommendations were made for implementation of a multiplane-multispeed balancing plan. Precision collars for the attachment of trial weights to a slender rotor were designed enabling demonstration balancing on production hardware. The quality of the balance was then evaluated by installing a high speed balanced power turbine in an engine and running in a test cell at the Corpus Christi Army depot. The engine used had been tested prior to the turbine changeout and showed acceptable overall vibration levels for the engine were significantly reduced, demonstrating the ability of multiplane-multispeed balancing to control engine vibration.

Sliding bearings are an important part of many large and critical components. They are widely used in power equipment, high-capacity pumps, compressors, electric motors and internal combustion engines (ICE). As a rule, sliding bearings include an antifriction bushing, part of the shaft surface (bearing journal), and a layer of oil between them. These are complex and critical parts in which there may occur dangerous defects, and which directly affect the durability, accuracy and reliability of the entire unit. To ensure high reliability of the equipment with sliding bearings applied in complex equipment, it is necessary to provide the quality control and sufficient level of monitoring of the technical condition, as well as diagnosis of emerging defects. This paper presents a comparative analysis of the internal combustion engines sliding bearings quality of various manufacturing companies. It gives operational properties of bearings depending on the compositional composition. The results of chemical analysis of the base, the cover and intermediate layers of the ICE liners are presented here. We have also made recommendations to increase the operational performance of sliding bearings.

The health-care facility environment is rarely implicated in disease transmission, except among patients who are immunocompromised. Nonetheless, inadvertent exposures to environmental pathogens (e.g., Aspergillus spp. and Legionella spp.) or airborne pathogens (e.g., Mycobacterium tuberculosis and varicella-zoster virus) can result in adverse patient outcomes and cause illness among health-care workers. Environmental infection-control strategies and engineering controls can effectively prevent these infections. The incidence of health-care--associated infections and pseudo-outbreaks can be minimized by 1) appropriate use of cleaners and disinfectants; 2) appropriate maintenance of medical equipment (e.g., automated endoscope reprocessors or hydrotherapy equipment); 3) adherence to water-quality standards for hemodialysis, and to ventilation standards for specialized care environments (e.g., airborne infection isolation rooms, protective environments, or operating rooms); and 4) prompt management of water intrusion into the facility. Routine environmental sampling is not usually advised, except for water quality determinations in hemodialysis settings and other situations where sampling is directed by epidemiologic principles, and results can be applied directly to infection-control decisions. This report reviews previous guidelines and strategies for preventing environment-associated infections in health-care facilities and offers recommendations. These include 1) evidence-based recommendations supported by studies; 2) requirements of federal agencies (e.g., Food and Drug Administration, U.S. Environmental Protection Agency, U.S. Department of Labor, Occupational Safety and Health Administration, and U.S. Department of Justice); 3) guidelines and standards from building and equipment professional organizations (e.g., American Institute of Architects, Association for the Advancement of Medical Instrumentation, and American Society of Heating, Refrigeration, and Air-Conditioning Engineers); 4) recommendations derived from scientific theory or rationale; and 5) experienced opinions based upon infection-control and engineering practices. The report also suggests a series of performance measurements as a means to evaluate infection-control efforts.

Recent emphasis on shared decision making and patient-centered research has increased the importance of patient education and health literacy. The internet is rapidly growing as a source of self-education for patients. However, concern exists over the quality, accuracy, and readability of the information. Our objective was to determine whether the quality, accuracy, and readability of information online about distal radius fractures vary with the search term. This was a prospective evaluation of 3 search engines using 3 different search terms of varying sophistication ("distal radius fracture," "wrist fracture," and "broken wrist"). We evaluated 70 unique Web sites for quality, accuracy, and readability. We used comparative statistics to determine whether the search term affected the quality, accuracy, and readability of the Web sites found. Three orthopedic surgeons independently gauged quality and accuracy of information using a set of predetermined scoring criteria. We evaluated the readability of the Web site using the Fleisch-Kincaid score for reading grade level. There were significant differences in the quality, accuracy, and readability of information found, depending on the search term. We found higher quality and accuracy resulted from the search term "distal radius fracture," particularly compared with Web sites resulting from the term "broken wrist." The reading level was higher than recommended in 65 of the 70 Web sites and was significantly higher when searching with "distal radius fracture" than "wrist fracture" or "broken wrist." There was no correlation between Web site reading level and quality or accuracy. The readability of information about distal radius fractures in most Web sites was higher than the recommended reading level for the general public. The quality and accuracy of the information found significantly varied with the sophistication of the search term used. Physicians, professional societies, and search engines should consider efforts to improve internet access to high-quality information at an understandable level.

This study was designed to ascertain the quality of patient information available on the World Wide Web on the topic of knee arthroscopy. For the purpose of quality analysis, we used a pool of 232 search results obtained from 7 different search engines. We used a modified assessment questionnaire to assess the quality of these Web sites. This questionnaire was developed based on similar studies evaluating Web site quality and includes items on illustrations, accessibility, availability, accountability, and content of the Web site. We also compared results obtained with different search engines and tried to establish the best possible search strategy to attain the most relevant, authentic, and adequate information with minimum time consumption. For this purpose, we first compared 100 search results from the single most commonly used search engine (AltaVista) with the pooled sample containing 20 search results from each of the 7 different search engines. The search engines used were metasearch (Copernic and Mamma), general search (Google, AltaVista, and Yahoo), and health topic-related search engines (MedHunt and Healthfinder). The phrase "knee arthroscopy" was used as the search terminology. Excluding the repetitions, there were 117 Web sites available for quality analysis. These sites were analyzed for accessibility, relevance, authenticity, adequacy, and accountability by use of a specially designed questionnaire. Our analysis showed that most of the sites providing patient information on knee arthroscopy contained outdated information, were inadequate, and were not accountable. Only 16 sites were found to be providing reasonably good patient information and hence can be recommended to patients. Understandably, most of these sites were from nonprofit organizations and educational institutions. Furthermore, our study revealed that using multiple search engines increases patients' chances of obtaining more relevant information rather than using a single search engine. Our study shows the difficulties encountered by patients in obtaining information regarding knee arthroscopy and highlights the duty of knee surgeons in helping patients to identify the relevant and authentic information in the most efficient manner from the World Wide Web. This study highlights the importance of the role of orthopaedic surgeons in helping their patients to identify the best possible information on the World Wide Web.

Integrating two distinct and complementary paradigms, science and engineering, may produce more effective outcomes for the implementation of evidence-based practices in health care settings. Science formalizes and tests innovations, whereas engineering customizes and optimizes how the innovation is applied tailoring to accommodate local conditions. Together they may accelerate the creation of an evidence-based healthcare system that works effectively in specific health care settings. We give examples of applying engineering methods for better quality, more efficient, and safer implementation of clinical practices, medical devices, and health services systems. A specific example was applying systems engineering design that orchestrated people, process, data, decision-making, and communication through a technology application to implement evidence-based depression care among low-income patients with diabetes. We recommend that leading journals recognize the fundamental role of engineering in implementation research, to improve understanding of design elements that create a better fit between program elements and local context.

The quantity of medical equipment in hospital rise quickly recent year. It provides the comprehensive support to the clinical service. The maintenance of medical equipment becomes more important than before. It is necessary to study on the orientation and function of clinical engineer in medical equipment maintenance system. Refer to three grade health care system, the community doctors which is called General practitioner, play an important role as the gatekeeper of health care system to triage and cost control. The paper suggests that hospital clinical engineer should play similar role as the gatekeeper of medical equipment maintenance system which composed by hospital clinical engineer, manufacture engineer and third party engineer. The hospital clinical engineer should be responsible of guard a pass of medical equipment maintenance quality and cost control. As the gatekeeper, hospital clinical engineer should take the responsibility of "General engineer" and pay more attention to safety and health of medical equipment. The responsibility description and future transition? development of clinical engineer as "General Engineer" is discussed. More attention should be recommended to the team building of hospital clinical engineer as "General Engineer".

Learners often utilize online resources to supplement formalized curricula, and to appropriately support learning, these resources should be of high quality. Thus, the objectives of this study are to develop and provide validity evidence supporting an assessment tool designed to assess the quality of educational websites in Otolaryngology- Head & Neck Surgery (ORL-HNS), and identify those that could support effective web-based learning. METHODS: After a literature review, the Modified Education in Otolaryngology Website (MEOW) assessment tool was designed by a panel of experts based on a previously validated website assessment tool. A search strategy using a Google-based search engine was used subsequently to identify websites. Those that were free of charge and in English were included. Websites were coded for whether their content targeted medical students or residents. Using the MEOW assessment tool, two independent raters scored the websites. Inter-rater and intra-rater reliability were evaluated, and scores were compared to recommendations from a content expert. The MEOW assessment tool included a total of 20 items divided in 8 categories related to authorship, frequency of revision, content accuracy, interactivity, visual presentation, navigability, speed and recommended hyperlinks. A total of 43 out of 334 websites identified by the search met inclusion criteria. The scores generated by our tool appeared to differentiate higher quality websites from lower quality ones: websites that the expert "would recommend" scored 38.4 (out of 56; CI [34.4-42.4]) and "would not recommend" 27.0 (CI [23.2-30.9]). Inter-rater and intra-rater intraclass correlation coefficient were greater than 0.7. Using the MEOW assessment tool, high quality ORL-HNS educational websites were identified.

Convergence of medicine and Internet may be one of the most remarkable transformations in the health care business. Following the path led by the United States, the number of French websites related to cosmetic surgery is growing rapidly. In this study, we intend to assess the quality of French websites dedicated to cosmetic surgery regarding good quality criteria currently available and recommendations suggested by the French Medical Association. We browsed the main French search engines on the Web that initially answering the following question: how many webpages are available regarding cosmetic surgery and what are the best referenced websites. For each website, we surveyed the following data: author's name and qualification, date of creation and last update, sources of information, level of interactivity, and adherence to a chart of quality such as HON. Eighty-five websites were surveyed and assessed. Forty-five French websites were active websites dedicated to cosmetic surgery. Websites are mainly hosted by private clinics (18 sites = 40%), with informative content. We found that no website adheres to any chart of quality, and the French Society for Plastic Surgery (SOF.C.P.R.E.) is never mentioned. Intrinsic quality criteria for websites (author's identification, last update, sources of information, confidentiality) are only partially present. We recall the key statistics regarding e-health business in the world, the various charts of quality available for medical websites, and recommendations provided by the French Medical Association. We suggest that websites should be available as a service (for information to the patient, for managing the office, for setting up medical records) rather than a poor personal webpage or a showcase. The quality of websites for cosmetic surgery is poor; however, as in the USA, the number of web surfers on medical sites is growing. Online presence of our speciality should evolve. To improve medical websites, collective awareness is required. We recommend using a specific chart of quality, with recommendations rather than constraints.

There exists a large body of scientific evidence to support protein intakes in excess of the recommended dietary allowance (RDA) (0.8 g protein/kg/day) to promote the retention of skeletal muscle and loss of adipose tissue during dietary energy restriction. Diet-induced weight loss with as low as possible ratio of skeletal muscle to fat mass loss is a situation we refer to as high-quality weight loss. We propose that high-quality weight loss is often of importance to elite athletes in order to maintain their muscle (engine) and shed unwanted fat mass, potentially improving athletic performance. Current recommendations for protein intakes during weight loss in athletes are set at 1.6-2.4 g protein/kg/day. However, the severity of the caloric deficit and type and intensity of training performed by the athlete will influence at what end of this range athletes choose to be. Other considerations regarding protein intake that may help elite athletes achieve weight loss goals include the quality of protein consumed, and the timing and distribution of protein intake throughout the day. This review highlights the scientific evidence used to support protein recommendations for high-quality weight loss and preservation of performance in athletes. Additionally, the current knowledge surrounding the use of protein supplements, branched chain amino acids (BCAA), β-hydroxy β-methylbutyrate (HMB), and other dietary supplements with weight loss claims will be discussed.

Patients often use the internet as a source of information about their condition and treatments. However, this information is unregulated and varies in quality. To evaluate the readability and quality of online information for pediatric and adult patients and caregivers regarding sclerotherapy for venous malformations. "Venous malformation sclerotherapy" was entered into Google, and results were reviewed until 20 sites that satisfied predefined inclusion criteria were identified. Scientific and non-patient-focused web pages were excluded. Readability was assessed using the Flesch Reading Ease Score and American Medical Association reading difficulty recommendations and quality was assessed using Journal of the American Medical Association standards and assessing if the site displayed HONcode (Health on the Net Code) certification. Assessment of the breadth of relevant information was made using a predefined checklist. Forty-nine search engine results were reviewed before 20 sites were identified for analysis. Average Flesch Reading Ease Score was 44 (range: 24.2-70.1), representing a "fairly difficult" reading level. None of the sites had a Flesch Reading Ease Score meeting the American Medical Association recommendation of 80-90. Only one site met all four Journal of the American Medical Association quality criteria (average: 2.1). None of the sites displayed a HONcode seal. The information most frequently found was: sclerotherapy is performed by radiologists, multiple treatments may be needed and surgery is an alternative treatment. Online information regarding sclerotherapy for venous malformations is heterogeneous in quality and breadth of information, and does not meet readability recommendations for patient information. Radiologists should be aware of and account for this when meeting patients.

Hydraulic fluids and jet engine oil: pyrolysis and aircraft air quality.
van Netten, C; Leung, V
2001-01-01
Incidents of smoke in aircraft cabins often result from jet engine oil and/or hydraulic fluid that leaks into ventilation air, which can be subjected to temperatures that exceed 500 degrees C. Exposed flight-crew members have reported symptoms, including dizziness, nausea, disorientation, blurred vision, and tingling in the legs and arms. In this study, the authors investigated pyrolysis products of one jet engine oil and two hydraulic fluids at 525 degrees C. Engine oil was an important source of carbon monoxide. Volatile agents and organophosphate constituents were released from all the agents tested; however, the neurotoxin trimethyl propane phosphate was not found. The authors hypothesized that localized condensation of pyrolysis products in ventilation ducts, followed by mobilization when cabin heat demand was high, accounted for mid-flight incidents. The authors recommended that carbon monoxide data be logged continuously to capture levels during future incidents.

2015-07-01
The focus on biodiesel research has shown a tremendous growth over the last few years. Several microbial and plant sources are being explored for the sustainable biodiesel production to replace the petroleum diesel. Conventional methods of biodiesel production have several limitations related to yield and quality, which led to development of new engineering strategies to improve the biodiesel production in plants, and microorganisms. Substantial progress in utilizing algae, yeast, and Escherichia coli for the renewable production of biodiesel feedstock via genetic engineering of fatty acid metabolic pathways has been reported in the past few years. However, in most of the cases, the successful commercialization of such engineering strategies for sustainable biodiesel production is yet to be seen. This paper systematically presents the drawbacks in the conventional methods for biodiesel production and an exhaustive review on the present status of research in genetic engineering strategies for production of biodiesel in plants, and microorganisms. Further, we summarize the technical challenges need to be tackled to make genetic engineering technology economically sustainable. Finally, the need and prospects of genetic engineering technology for the sustainable biodiesel production and the recommendations for the future research are discussed.
Verification of Decision-Analytic Models for Health Economic Evaluations: An Overview.
Dasbach, Erik J; Elbasha, Elamin H
2017-07-01
Decision-analytic models for cost-effectiveness analysis are developed in a variety of software packages where the accuracy of the computer code is seldom verified. Although modeling guidelines recommend using state-of-the-art quality assurance and control methods for software engineering to verify models, the fields of pharmacoeconomics and health technology assessment (HTA) have yet to establish and adopt guidance on how to verify health and economic models. The objective of this paper is to introduce to our field the variety of methods the software engineering field uses to verify that software performs as expected. We identify how many of these methods can be incorporated in the development process of decision-analytic models in order to reduce errors and increase transparency. Given the breadth of methods used in software engineering, we recommend a more in-depth initiative to be undertaken (e.g., by an ISPOR-SMDM Task Force) to define the best practices for model verification in our field and to accelerate adoption. Establishing a general guidance for verifying models will benefit the pharmacoeconomics and HTA communities by increasing accuracy of computer programming, transparency, accessibility, sharing, understandability, and trust of models.

The objective of the systems engineering task was to develop and implement an approach that would generate the required study products as defined by program directives. This product list included a set of system and subsystem requirements, a complete set of optimized trade studies and analyses resulting in a recommended system configuration, and the definition of an integrated system/technology and advanced development growth path. A primary ingredient in the approach was the TQM philosophy stressing job quality from the inception. Included throughout the Systems Engineering, Programmatics, Concepts, Flight Design, and Technology sections are data supporting the original objectives as well as supplemental information resulting from program activities. The primary result of the analyses and studies was the recommendation of a single propulsion stage Lunar Transportation System (LTS) configuration that supports several different operations scenarios with minor element changes. This concept has the potential to support two additional scenarios with complex element changes. The space based LTS concept consists of three primary configurations--Piloted, Reusable Cargo, and Expendable Cargo.
Role to Be Played by Independent Geotechnical Supervision in the Foundation for Bridge Construction
NASA Astrophysics Data System (ADS)
Sobala, Dariusz; Rybak, Jarosław
2017-10-01
Some remarks concerning the necessity of employing an independent and over all ethical geotechnical survey were presented in the paper. Starting from the design phase, through the whole construction process, the importance of geotechnical engineer is stated in legal acts. Numerous testing technologies serve for the calibration of geotechnical technologies and allow for confirming the quality and capacity of piles. Special emphasis was payed to the involvement of scientifical and research institutions which can not only serve services but also can postprocess and methodize collected data. Such databases enable for new codes, methods and recommendations. Selection of deep foundations for bridge-type structures is most often dependent on complex geotechnical conditions, concentrated loads and constraints for pier displacements. Besides the last ones, prior to more common introduction of the design-construct system, could be a convenient justification for design engineer, who imposed deep foundation because he did not want or was not able to estimate the effect of pier settlement on civil engineering structure. The paper provides some notes about the need to engage a geotechnical supervising service of high competency and ethical quality during engineering and construction stages of foundations for bridge-type structures where legal requirements are of special consideration. Successive stages of projects are reviewed and research methods used for current calibration of geotechnical technologies and verification of geotechnical work quality are analysed. Special attention is given to potential involvement of independent R&D institutions which, apart from rendering specific services, also collect and systemize the research results thus enabling, in the long term, to revise engineering standards, instructions and guidelines.

The objective was to provide an overview of the recommendations and quality of evidence-based clinical practice guidelines (CPGs) for the emergency management of mild traumatic brain injury (mTBI), with a view to informing best practice and improving the consistency of recommendations. Electronic searches of health databases (MEDLINE, EMBASE, The Cochrane Library, PsycINFO), CPG clearinghouse websites, CPG developer websites, and Internet search engines up to January 2010 were conducted. CPGs were included if 1) they were published in English and freely accessible, 2) their scope included the management of mTBI in the emergency department (ED), 3) the date of last search was within the past 10 years (2000 onward), 4) systematic methods were used to search for evidence, and 5) there was an explicit link between the recommendations and the supporting evidence. Four authors independently assessed the quality of the included CPGs using the Appraisal of Guidelines, Research and Evaluation (AGREE) Instrument. The authors extracted and categorized recommendations according to initial clinical assessment, imaging, management, observation, discharge planning, and patient information and follow-up. The search identified 18 potential CPGs, of which six met the inclusion criteria. The included CPGs varied in scope, target population, size, and guideline development processes. Four CPGs were assessed as "strongly recommended." The majority of CPGs did not provide information about the level of stakeholder involvement (mean AGREE standardized domain score = 57%, range = 25% to 81%), nor did they address the organizational/cost implications of applying the recommendations or provide criteria for monitoring and review of recommendations in practice (mean AGREE standardized domain score = 46.6%, range = 19% to 94%). Recommendations were mostly consistent in terms of the use of the Glasgow Coma Scale (GCS) score (adult and pediatric) to assess the level of consciousness, initial assessment criteria, the use of computed tomography (CT) scanning as imaging investigation of choice, and the provision of patient information. The CPGs defined mTBI in a variety of ways and described different rules to determine the need for CT scanning and therefore used different criteria to identify high-risk patients. Higher-quality CPGs for mTBI are consistent in their recommendations about assessment, imaging, and provision of patient information. There is not, however, an agreed definition of mTBI, and the quality of future CPGs could be improved with better reporting of stakeholder involvement, procedures for updating, and greater consideration of the applicability of the recommendations (cost implications, monitoring procedures). Nevertheless, guideline developers may benefit from adapting existing CPGs to their local context rather than investing in developing CPGs de novo. © 2011 by the Society for Academic Emergency Medicine.
ISO 9000 and/or Systems Engineering Capability Maturity Model?

2002-01-01
For businesses and organizations to remain competitive today they must have processes and systems in place that will allow them to first identify customer needs and then develop products/processes that will meet or exceed the customers needs and expectations. Customer needs, once identified, are normally stated as requirements. Designers can then develop products/processes that will meet these requirements. Several functions, such as quality management and systems engineering management are used to assist product development teams in the development process. Both functions exist in all organizations and both have a similar objective, which is to ensure that developed processes will meet customer requirements. Are efforts in these organizations being duplicated? Are both functions needed by organizations? What are the similarities and differences between the functions listed above? ISO 9000 is an international standard of goods and services. It sets broad requirements for the assurance of quality and for management's involvement. It requires organizations to document the processes and to follow these documented processes. ISO 9000 gives customers assurance that the suppliers have control of the process for product development. Systems engineering can broadly be defined as a discipline that seeks to ensure that all requirements for a system are satisfied throughout the life of the system by preserving their interrelationship. The key activities of systems engineering include requirements analysis, functional analysis/allocation, design synthesis and verification, and system analysis and control. The systems engineering process, when followed properly, will lead to higher quality products, lower cost products, and shorter development cycles. The System Engineering Capability Maturity Model (SE-CMM) will allow companies to measure their system engineering capability and continuously improve those capabilities. ISO 9000 and SE-CMM seem to have a similar objective, which is to document the organization's processes and certify to potential customers the capability of a supplier to control the processes that determine the quality of the product or services being produced. The remaining sections of this report examine the differences and similarities between ISO 9000 and SE-CMM and make recommendations for implementation.

The International Maritime Organization (IMO) has moved to address the health and climate impact of the emissions from the combustion of low-quality residual fuels within the commercial shipping industry. Fuel sulfur content (FS) limits and an efficiency design index for future ships are examples of such IMO actions. The impacts of black carbon (BC) emissions from shipping are now under review by the IMO, with a particular focus on the potential impacts of future Arctic shipping. Recognizing that associating impacts with BC emissions requires both ambient and onboard observations, we provide recommendations for the measurement of BC. We also evaluate current insights regarding the effect of ship speed (engine load), fuel quality and exhaust gas scrubbing on BC emissions from ships. Observations demonstrate that BC emission factors (EFBC) increases 3 to 6 times at very low engine loads (<25% compared to EFBC at 85-100% load); absolute BC emissions (per nautical mile of travel) also increase up to 100% depending on engine load, even with reduced load fuel savings. If fleets were required to operate at lower maximum engine loads, presumably associated with reduced speeds, then engines could be re-tuned, which would reduce BC emissions. Ships operating in the Arctic are likely running at highly variable engine loads (25-100%) depending on ice conditions and ice breaking requirements. The ships operating at low load may be emitting up to 50% more BC than they would at their rated load. Such variable load conditions make it difficult to assess the likely emissions rate of BC. Current fuel sulfur regulations have the effect of reducing EFBC by an average of 30% and potentially up to 80% regardless of engine load; a removal rate similar to that of scrubbers. Uncertainties among current observations demonstrate there is a need for more information on (a) the impact of fuel quality on EFBC using robust measurement methods and (b) the efficacy of scrubbers for the removal of particulate matter by size and composition.

The quality of information on the Internet on orthodontic retainer wear: a cross-sectional study.
Doğramacı, Esma J; Rossi-Fedele, Giampiero
2016-03-01
The objectives of this study were to assess the accessibility, usability, reliability and quality of information on the Internet written for the lay public about orthodontic retainers, and to elucidate the different retention protocols encouraged. A cross-sectional, observational study. Online, using a computer connected to the Internet in Australia. Two search terms; 'orthodontic retainer' and 'how long should someone wear a retainer after their braces are removed?' were entered alternatively into five search engines. Twenty results for each search term per search engine that fulfilled the inclusion criteria were evaluated in terms of accessibility, usability, reliability and quality of information using the LIDA and DISCERN instruments, ensuring there were no internal or cross-search engine duplicates. Any information about frequency and duration of retainer wear was also collected. Two hundred different websites were identified and assessed. The median overall LIDA score was 72%, corresponding to a moderate quality level. The median total DISCERN score was 47%. Twenty-two websites recommended patients adhere to the specific protocol prescribed to them by their practitioner. There were 45 (22.5%) and 28 (14%) websites advising indefinite use of removable and bonded retainers respectively. Information about retainers on the Internet is easily accessible and usable, though the quality of the content is generally of a moderate level. However, the information is not always accurate and reliable. Both full-time and part-time wear of removable retainers was suggested over greatly varying time periods. Indefinite wear of removable and bonded retainers was also advocated.

Adult orthodontics: a quality assessment of Internet information.
McMorrow, Siobhán Mary; Millett, Declan T
2016-09-01
This study evaluated the quality, reliability and readability of information on the Internet on adult orthodontics. A quality assessment of adult orthodontic websites. Postgraduate Orthodontic Unit, Cork University Dental School and Hospital, Cork, Ireland. An Internet search using three search engines (Google, Yahoo and Bing) was conducted using the terms ('adult orthodontics' and 'adult braces'). The first 50 websites from each engine and under each search term were screened and exclusion criteria applied. Included websites were then assessed for quality using four methods: the HON seal, JAMA benchmarks, the DISCERN instrument and the LIDA tool. Readability of included websites was assessed using the Flesch Reading Ease Score (FRES). Only 13 websites met the inclusion criteria. Most were of US origin (n = 8; 61%). The authors of the websites were dentists (n = 5; 39%), professional organizations (n = 2; 15%), past patients (n = 2; 15%) and unspecified (n = 4; 31%). Only 1 website displayed the HON seal and three websites contained all JAMA benchmarks. The mean overall score for DISCERN was 3.9/5 and the mean total LIDA score was 115/144. The average FRES score was 63.1/100. The number of informative websites on adult orthodontics is low and these are of moderate quality. More accurate, high-quality Internet resources are required on adult orthodontics. Recommendations are made as to how this may be achieved.
A research review of quality assessment for software
NASA Technical Reports Server (NTRS)
1991-01-01
Measures were recommended to assess the quality of software submitted to the AdaNet program. The quality factors that are important to software reuse are explored and methods of evaluating those factors are discussed. Quality factors important to software reuse are: correctness, reliability, verifiability, understandability, modifiability, and certifiability. Certifiability is included because the documentation of many factors about a software component such as its efficiency, portability, and development history, constitute a class for factors important to some users, not important at all to other, and impossible for AdaNet to distinguish between a priori. The quality factors may be assessed in different ways. There are a few quantitative measures which have been shown to indicate software quality. However, it is believed that there exists many factors that indicate quality and have not been empirically validated due to their subjective nature. These subjective factors are characterized by the way in which they support the software engineering principles of abstraction, information hiding, modularity, localization, confirmability, uniformity, and completeness.

The structure of the industry which comprises 54 companies is outlined. In order to obtain sufficiently detailed and accurate data, each company was visited. Discussions were held with managers covering the areas of production, engineering, finance, design, sales and marketing, quality and other strategic issues affecting investment decision making. The study conclusions and recommendations are presented. An overview of the industry and the survey sample are given. Company performance, practice relationships which link practice, and performance are discussed.
Use of sediment quality guidelines
Wenning, R. J.; Batley, G. E.; Ingersoll, Christopher G.; Moore, David W.
2005-01-01
Are sediment quality guidelines (SQGs) adequately able to predict the presence or absence of chronic toxicity to sediment-dwelling organisms in field-collected sediments? Can SQGs predict effects resulting from the bioaccumulation of sediment-associated contaminants? Do SQGs define cause-and-effect relationships? Can they predict effects on organisms exposed in the field on the basis of amphipod mortality measured in the laboratory?These and other questions brought together 55 scientists from 8 countries for a Pellston Workshop convened by the Society of Environmental Toxicology and Chemistry (SETAC) in Fairmont, Montana, USA. In this book, these experts in ecology, ecotoxicology, engineering, environmental regulation, and risk assessment examine the scientific underpinnings of sediment quality guidelines and provide recommendations on the appropriate use of SQGs in the assessment and management of contaminated sediments.

The phenomenon of women's underrepresentation in engineering is well known. However, the slow progress in achieving better gender equality here compared with other domains has accentuated the 'numbers' issue, while the quality aspects have been largely ignored. This study aims to shed light on both these aspects via the lens of mentors, who are at the coalface of guiding female engineers through their education and subsequent careers. Based on data collected from 25 mentors (8 men and 17 women from 8 countries), the paper explores their experiences of being mentors, as well as their views on recommended actions for nurturing female engineers. The findings reveal that the primary motivation for becoming a mentor was personal for men and women. Many mentors from countries with relatively lower female labour participation rates perceive their roles as guarantors of their mentees' successful future career paths, and a similar trend can be found in mentors in academia. The study underscores the need for invigorating mentors' roles in order to secure a more equitable future for engineering education.

Schneider, H. W.
1984-01-01
The status of ongoing heat-engine developments, including spark-ignition, compression-ignition, internal-combustion, and external-combustion engines is presented. The potential of engine concepts under consideration for hybrid vehicle use is evaluated, using self-imposed criteria for selection. The deficiencies of the engines currently being evaluated in hybrid vehicles are discussed. Focus is on recent research with two-stroke, rotary, and free-piston engines. It is concluded that these engine concepts have the most promising potential for future application in hybrid vehicles. Recommendations are made for analysis and experimentation to evaluate stop-start and transient emission behavior of recommended engine concepts.
Evaluation of Game Engines for Cross-Platform Development of Mobile Serious Games for Health.
Kleinschmidt, Carina; Haag, Martin
2016-01-01
Studies have shown that serious games for health can improve patient compliance and help to increase the quality of medical education. Due to a growing availability of mobile devices, especially the development of cross-platform mobile apps is helpful for improving healthcare. As the development can be highly time-consuming and expensive, an alternative development process is needed. Game engines are expected to simplify this process. Therefore, this article examines the question whether using game engines for cross-platform serious games for health can simplify the development compared to the development of a plain HTML5 app. At first, a systematic review of the literature was conducted in different databases (MEDLINE, ACM and IEEE). Afterwards three different game engines were chosen, evaluated in different categories and compared to the development of a HTML5 app. This was realized by implementing a prototypical application in the different engines and conducting a utility analysis. The evaluation shows that the Marmalade engine is the best choice for development in this scenario. Furthermore, it is obvious that the game engines have great benefits against plain HTML5 development as they provide components for graphics, physics, sounds, etc. The authors recommend to use the Marmalade Engine for a cross-platform mobile Serious Game for Health.
A Systematic Method for Reviewing and Analyzing Health Information on Consumer-Oriented Websites.
Rew, Lynn; Saenz, Ashley; Walker, Lorraine O
2018-05-29
A discussion of a proposed method for analyzing the quality of consumer-oriented websites that provide health-related information. The quality of health information available to consumers online varies widely in quality. In an effort to improve the quality of online information, experts have undertaken systematic reviews on selected health topics; however, no standardized comprehensive methodology currently exists for such review. An eight-step method is recommended embracing the following steps: (1) select topic; (2) determine the purpose of the analysis; (3) select search terms and engines; (4) develop and apply website inclusion and exclusion criteria; (5) develop processes and tools to manage search results; (6) specify measures of quality; (7) compute readability; (8) evaluate websites. Each of these steps is illustrated in relation to the health topic of gynecomastia, a physical and mental health challenge for many adolescent males and young men. Although most extant analyses of consumer-oriented websites have focused on disease conditions and their treatment, website-analysis methodology would encourage analyses that fall into the nursing care domain. The method outlined in this paper is intended to provide nurses and others who work with specific patient populations with the tools needed for website analytic studies. Such studies provide a foundation for making recommendations about quality websites, as well as identifying gaps in online information for health consumers. This article is protected by copyright.

The recent emphasis on shared decision-making has increased the role of the Internet as a readily accessible medical reference source for patients and families. However, the lack of professional review creates concern over the quality, accuracy, and readability of medical information available to patients on the Internet. Three Internet search engines (Google, Yahoo, and Bing) were evaluated prospectively using 3 difference search terms of varying sophistication ("congenital hip dislocation," "developmental dysplasia of the hip," and "hip dysplasia in children"). Sixty-three unique Web sites were evaluated by each of 3 surgeons (2 fellowship-trained pediatric orthopaedic attendings and 1 orthopaedic chief resident) for quality and accuracy using a set of scoring criteria based on the AAOS/POSNA patient education Web site. The readability (literacy grade level) of each Web site was assessed using the Fleisch-Kincaid score. There were significant differences noted in quality, accuracy, and readability of information depending on the search term used. The search term "developmental dysplasia of the hip" provided higher quality and accuracy compared with the search term "congenital hip dislocation." Of the 63 total Web sites, 1 (1.6%) was below the sixth grade reading level recommended by the NIH for health education materials and 8 (12.7%) Web sites were below the average American reading level (eighth grade). The quality and accuracy of information available on the Internet regarding developmental hip dysplasia significantly varied with the search term used. Patients seeking information about DDH on the Internet may not understand the materials found because nearly all of the Web sites are written at a level above that recommended for publically distributed health information. Physicians should advise their patients to search for information using the term "developmental dysplasia of the hip" or, better yet, should refer patients to Web sites that they have personally reviewed for content and clarity. Orthopaedic surgeons, professional societies, and search engines should undertake efforts to ensure that patients have access to information about DDH that is both accurate and easily understandable.

Background Clostridium difficile is the leading cause of health care–associated infections. Given the high incidence of C. difficile infection (CDI) and the lack of primary prevention through immunization, health care professionals should be aware of the most current guidance, as well as strengths and limitations of the evidence base underpinning this guidance. Methods We identified publicly available national or organizational guidelines related to CDI infection and prevention control (IPC) published between 2000 and 2015 and for any health care setting through an internet search using the Google search engine. We reviewed CDI–targeted IPC recommendations and describe the assessment of evidence in available guidelines. Results We identified documents from 28 countries/territories, mainly from acute care hospitals in North America, the Western Pacific, and Europe (18 countries). We identified only a few specific recommendations for long–term care facilities (LTCFs) and from countries in South America (Uruguay and Chile), South East Asia (Thailand), and none for Africa or Eastern Mediterranean. Of 10 IPC areas, antimicrobial stewardship was universally recognized as essential and supported by high quality evidence. Five other widely reported “strong” recommendations were: effective environment cleaning (including medical equipment), case isolation, use of personal protective equipment, surveillance, and education. Several unresolved and emerging issues were documented and currently available evidence was classified mainly as of mixed quality. Conclusion Our review underlines the need for targeted CDI IPC guidelines in several countries and for LTCFs. International harmonisation on the assessment of the evidence for best practices is needed as well as more robust evidence to support targeted recommendations. PMID:28028434

Reporting on post-menopausal hormone therapy: an analysis of gynaecologists' web pages.
Bucksch, Jens; Kolip, Petra; Deitermann, Bernhilde
2004-01-01
The present study was designed to analyse Web pages of German gynaecologists with regard to postmenopausal hormone therapy (HT). There is a growing body of evidence, that the overall health risks of HT exceed the benefits. Making one's own informed choice has become a central concern for menopausal women. The Internet is an important source of health information, but the quality is often dubious. The study focused on the analysis of basic criteria such as last modification date and quality of the HT information content. The results of the Women's Health Initiative Study (WHI) were used as a benchmark. We searched for relevant Web pages by entering a combination of key words (9 x 13 = 117) into the search engine www.google.de. Each Web page was analysed using a standardized questionnaire. The basic criteria and the quality of content on each Web page were separately categorized by two evaluators. Disagreements were resolved by discussion. Of the 97 websites identified, basic criteria were not met by the majority. For example, the modification date was displayed by only 23 (23.7%) Web pages. The quality of content of most Web pages regarding HT was inaccurate and incomplete. Whilst only nine (9.3%) took up a balanced position, 66 (68%) recommended HT without any restrictions. In 22 cases the recommendation was indistinct and none of the sites refused HT. With regard to basic criteria, there was no difference between HT-recommending Web pages and sites with balanced position. Evidence-based information resulting from the WHI trial was insufficiently represented on gynaecologists' Web pages. Because of the growing number of consumers looking online for health information, the danger of obtaining harmful information has to be minimized. Web pages of gynaecologists do not appear to be recommendable for women because they do not provide recent evidence-based findings about HT.

Critical reagents are essential components of ligand binding assays (LBAs) and are utilized throughout the process of drug discovery, development, and post-marketing monitoring. Successful lifecycle management of LBA critical reagents minimizes assay performance problems caused by declining reagent activity and can mitigate the risk of delays during preclinical and clinical studies. Proactive reagent management assures adequate supply. It also assures that the quality of critical reagents is appropriate and consistent for the intended LBA use throughout all stages of the drug development process. This manuscript summarizes the key considerations for the generation, production, characterization, qualification, documentation, and management of critical reagents in LBAs, with recommendations for antibodies (monoclonal and polyclonal), engineered proteins, peptides, and their conjugates. Recommendations are given for each reagent type on basic and optional characterization profiles, expiration dates and storage temperatures, and investment in a knowledge database system. These recommendations represent a consensus among the authors and should be used to assist bioanalytical laboratories in the implementation of a best practices program for critical reagent life cycle management.

The main motivating factor driving this research is to find differences between the automotive related companies in Malaysia and Indonesia with regard to quality engineering (QE) implementation. A comparative study between Malaysia and Indonesia provides the opportunity to gain perspective and thorough understanding of the similarities and differences on the critical factors for successful QE practices in the context of both these countries. Face to face interviews are used to compare the QE practices in two automotive companies in Malaysia and Indonesia, respectively. The findings of study showed that both countries have clear quality objectives to achieving zero defects in processes and products and total customer satisfaction. Top and middle management in both countries were found to be directly involved in quality improvement on the shop floor to provide On-The-Job training and actively encourage team members to perform quality problem solving through the formation of quality control circles (QCC) particularly in Indonesia automotive industry. In Malaysia automotive industry, the implementation was not fully effective, but they have started to cultivate those values in the daily execution. Based on the case study results and analysis, the researcher has provided suggestions for both countries as an improvement plan for successful QE implementation. These recommendations will allow management to implement appropriate strategies for better QE implementation which hopefully can improve company's performance and ultimately the making the automotive industry in both countries to reach world class quality. It is strongly believed that the findings of this study can help Malaysia and Indonesia automotive industries in their efforts to become more effective and competitive.

The Committee on Man and Radiation (COMAR) is a technical committee of the Engineering in Medicine and Biology Society (EMBS) of the Institute of Electrical and Electronics Engineers (IEEE). Its primary area of interest is biological effects of non-ionizing electromagnetic radiation, including radiofrequency (RF) energy. The public interest in possible health effects attributed to RF energy, such as emitted by mobile phones, wireless telephone base stations, TV and radio broadcasting facilities, Wi-Fi systems and many other sources, has been accompanied by commentary in the media that varies considerably in reliability and usefulness for their audience. The focus of this COMAR Technical Information Statement is to identify quality sources of scientific information on potential health risks from exposure to RF energy. This Statement provides readers with references to expert reports and other reliable sources of information about this topic, most of which are available on the Internet. This report summarizes the conclusions from several major reports and comments on the markedly different conclusions in the BioInitiative Report (abbreviated BIR below). Since appearing on the Internet in August 2007, the BIR has received much media attention but, more recently, has been criticized by several health organizations (see Section titled "Views of health agencies about BIR"). COMAR concludes that the weight of scientific evidence in the RF bioeffects literature does not support the safety limits recommended by the BioInitiative group. For this reason, COMAR recommends that public health officials continue to base their policies on RF safety limits recommended by established and sanctioned international organizations such as the Institute of Electrical and Electronics Engineers International Committee on Electromagnetic Safety and the International Commission on Non-Ionizing Radiation Protection, which is formally related to the World Health Organization.
Recommendations to Sustain the Academic Mission Ecosystem at U.S. Medical Schools.
Kerschner, Joseph E; Hedges, Jerris R; Antman, Karen; Abraham, Edward; Colón Negrón, Edgar; Jameson, J Larry
2018-07-01
Academic medical center (AMC) faculty, administrators, and leaders have the critical tasks of teaching and training the next generation of health care providers and biomedical researchers, as well as generating new knowledge that improves the health of all. In the United States, medical schools and their affiliated hospitals train remarkably high-quality physicians and scientists, and the research conducted at these institutions results in advances in health. To that end, AMCs have become essential engines for driving better health in the United States and the rest of the world; they also have become essential engines driving the economies of their respective communities and regions. The education and research missions, however, require subsidization because tuition and extramural grant funding do not cover the costs of these endeavors. This subsidization largely has come from revenues generated by AMCs' clinical endeavors. The viability of this cross-subsidization, however, is increasingly threatened in the current clinical environment. The authors of this Perspective discuss these issues in depth and provide some concrete recommendations to address these challenges. They hope to stimulate discussion and, ultimately, ensure the financial viability of U.S. AMCs-a national resource of utmost importance. Recommendations to sustain research include creating strategic biomedical research plans, developing a defined and sustained model to support National Institutes of Health funding that keeps pace with inflation, and evolving funding mechanisms. Recommendations to sustain medical education include limiting student debt, creating more cost-effective curricula, and ensuring that clinical training opportunities that meet national standards are available to students.
Teaching introductory game development with unreal engine: Challenges, strategies, and experiences
NASA Astrophysics Data System (ADS)
Head, Nicholas A.
From the days of Pong to 100 million dollar projects such as the Grand Theft Auto franchise, video games have evolved significantly over the years. This evolution has also changed the way game development is viewed as a career. Today, video games are one of the most profitable forms of entertainment, and game development courses are appearing at universities around the world. Even with this growth, a degree from a university has yet to be an important factor in finding a job in game development (Owen, 2013). This thesis examines a method of creating and implementing an introductory gaming course and recommends ways to improve the curriculum. The main focus of the course was to introduce game development to the students. Each week, they were given an exercise that covered a different topic. Students also took part in a team project in which they were tasked with creating a complete game. The goal of the team projects was to expand the student's basic knowledge given to them from the exercises. Data was gathered on the students' subjective experiences with the class. This data and the class's overall performance were compared with past iterations of the course. New to the course was the Unreal Engine. Students used the latest version of the engine, Unreal Engine 4, to complete exercises. Not all students chose to use this engine for the team project. Instructor and students experiences with the engine were also recorded. While there were some problems implementing the engine within our lab environment, we were still able to execute the overall lesson plan. Even with the engine issues, the course had overall good performance. CGT 241, Introduction to 3D Animation, was shown to help the students to complete the course while CGT 215, Computer Graphics Programming I, did not provide enough information on game programming. Exercises were found to be helpful but students wanted a better understanding of how these skills can be applied to game development. Team projects also went well with most teams creating a functional project. Students wanted more time to complete projects along with a structured approach to the project. Confidence in game development and the Unreal Engine were not high but students were enthusiastic in continuing in the field of game development. Recommendations were made to the curriculum in order to fix some of the issues with the introductory course and help students find a career. In order to fix the gap between the programming course and the introductory game course, a video game programming course was recommended that focused on teaching students how code works with video game engines. An option to specialize was also recommended in order to see a higher level of understanding on game concepts and a higher level of quality of game projects. Changes to the higher courses were also made for a yearlong course where students would focus on a single project to publish. This would expand on the introductory course while also replicating the game development process.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the removal of foreign bodies in the upper gastrointestinal tract in adults. Recommendations Nonendoscopic measures 1 ESGE recommends diagnostic evaluation based on the patient's history and symptoms. ESGE recommends a physical examination focused on the patient's general condition and to assess signs of any complications (strong recommendation, low quality evidence). 2 ESGE does not recommend radiological evaluation for patients with nonbony food bolus impaction without complications. We recommend plain radiography to assess the presence, location, size, configuration, and number of ingested foreign bodies if ingestion of radiopaque objects is suspected or type of object is unknown (strong recommendation, low quality evidence). 3 ESGE recommends computed tomography (CT) scan in all patients with suspected perforation or other complication that may require surgery (strong recommendation, low quality evidence). 4 ESGE does not recommend barium swallow, because of the risk of aspiration and worsening of the endoscopic visualization (strong recommendation, low quality evidence). 5 ESGE recommends clinical observation without the need for endoscopic removal for management of asymptomatic patients with ingestion of blunt and small objects (except batteries and magnets). If feasible, outpatient management is appropriate (strong recommendation, low quality evidence). 6 ESGE recommends close observation in asymptomatic individuals who have concealed packets of drugs by swallowing ("body packing"). We recommend against endoscopic retrieval. We recommend surgical referral in cases of suspected packet rupture, failure of packets to progress, or intestinal obstruction (strong recommendation, low quality evidence). Endoscopic measures 7 ESGE recommends emergent (preferably within 2 hours, but at the latest within 6 hours) therapeutic esophagogastroduodenoscopy for foreign bodies inducing complete esophageal obstruction, and for sharp-pointed objects or batteries in the esophagus. We recommend urgent (within 24 hours) therapeutic esophagogastroduodenoscopy for other esophageal foreign bodies without complete obstruction (strong recommendation, low quality evidence). 8 ESGE suggests treatment of food bolus impaction in the esophagus by gently pushing the bolus into the stomach. If this procedure is not successful, retrieval should be considered (weak recommendation, low quality evidence). The effectiveness of medical treatment of esophageal food bolus impaction is debated. It is therefore recommended, that medical treatment should not delay endoscopy (strong recommendation, low quality evidence). 9 In cases of food bolus impaction, ESGE recommends a diagnostic work-up for potential underlying disease, including histological evaluation, in addition to therapeutic endoscopy (strong recommendation, low quality evidence). 10 ESGE recommends urgent (within 24 hours) therapeutic esophagogastroduodenoscopy for foreign bodies in the stomach such as sharp-pointed objects, magnets, batteries and large/long objects. We suggest nonurgent (within 72 hours) therapeutic esophagogastroduodenoscopy for medium-sized blunt foreign bodies in the stomach (strong recommendation, low quality evidence). 11 ESGE recommends the use of a protective device in order to avoid esophagogastric/pharyngeal damage and aspiration during endoscopic extraction of sharp-pointed foreign bodies. Endotracheal intubation should be considered in the case of high risk of aspiration (strong recommendation, low quality evidence). 12 ESGE suggests the use of suitable extraction devices according to the type and location of the ingested foreign body (weak recommendation, low quality evidence). 13 After successful and uncomplicated endoscopic removal of ingested foreign bodies, ESGE suggests that the patient may be discharged. If foreign bodies are not or cannot be removed, a case-by-case approach depending on the size and type of the foreign body is suggested (weak recommendation, low quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Background Human papillomavirus (HPV) vaccination rates fall far short of Healthy People 2020 objectives. A leading reason is that clinicians do not recommend the vaccine consistently and strongly to girls and boys in the age group recommended for vaccination. Although Web-based HPV vaccine educational interventions for clinicians have been created to promote vaccination recommendations, rigorous evaluations of these interventions have not been conducted. Such evaluations are important to maximize the efficacy of educational interventions in promoting clinician recommendations for HPV vaccination. Objective The objectives of our study were (1) to expand previous research by systematically identifying HPV vaccine Web-based educational interventions developed for clinicians and (2) to evaluate the quality of these Web-based educational interventions as defined by access, content, design, user evaluation, interactivity, and use of theory or models to create the interventions. Methods Current HPV vaccine Web-based educational interventions were identified from general search engines (ie, Google), continuing medical education search engines, health department websites, and professional organization websites. Web-based educational interventions were included if they were created for clinicians (defined as individuals qualified to deliver health care services, such as physicians, clinical nurses, and school nurses, to patients aged 9 to 26 years), delivered information about the HPV vaccine and how to increase vaccination rates, and provided continuing education credits. The interventions’ content and usability were analyzed using 6 key indicators: access, content, design, evaluation, interactivity, and use of theory or models. Results A total of 21 interventions were identified, out of which 7 (33%) were webinars, 7 (33%) were videos or lectures, and 7 (33%) were other (eg, text articles, website modules). Of the 21 interventions, 17 (81%) identified the purpose of the intervention, 12 (57%) provided the date that the information had been updated (7 of these were updated within the last 6 months), 14 (67%) provided the participants with the opportunity to provide feedback on the intervention, and 5 (24%) provided an interactive component. None of the educational interventions explicitly stated that a theory or model was used to develop the intervention. Conclusions This analysis demonstrates that a substantial proportion of Web-based HPV vaccine educational interventions has not been developed using established health education and design principles. Interventions designed using these principles may increase strong and consistent HPV vaccination recommendations by clinicians. PMID:29453187

The Management of Research and Development (R&D) is facing the challenges of reducing time from R&D to customer, reducing the cost of R&D, having higher accountability for results (improved quality), and increasing focus on customers. Concurrent engineering (CE) has shown great success in the automotive and technology industries resulting in significant decreases in cycle time, reduction of total cost, and increases in quality and reliability. This philosophy of concurrency can have similar implications or benefits for the management of R&D organizations. Since most studies on the application of CE have been performed in manufacturing environments, research into the benefits of CE into other environments is needed. This paper presents research conducted at the NASA Glenn Research Center (GRC) investigating the application of CE in the management of an R&D organization. In particular the paper emphasizes possible barriers and enhancers that this environment presents to the successful implementation of CE. Preliminary results and recommendations are based on a series of interviews and subsequent surveys, from which data has been gathered and analyzed as part of the GRC's Continuous Improvement Process.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE), endorsed by the European Society for Radiotherapy and Oncology (ESTRO), the European Society of Digestive Endoscopy (ESDO), and the European Society for Clinical Nutrition and Metabolism (ESPEN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations for malignant disease 1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliative treatment of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass (strong recommendation, high quality evidence). 2 For patients with longer life expectancy, ESGE recommends brachytherapy as a valid alternative or in addition to stenting in esophageal cancer patients with malignant dysphagia. Brachytherapy may provide a survival advantage and possibly a better quality of life compared to SEMS placement alone. (Strong recommendation, high quality evidence.) 3 ESGE recommends esophageal SEMS placement as the preferred treatment for sealing malignant tracheoesophageal or bronchoesophageal fistula (strong recommendation, low quality evidence). 4 ESGE does not recommend the use of concurrent external radiotherapy and esophageal stent treatment. SEMS placement is also not recommended as a bridge to surgery or prior to preoperative chemoradiotherapy. It is associated with a high incidence of adverse events and alternative satisfactory options such as placement of a feeding tube are available. (Strong recommendation, low quality evidence.) Main recommendations for benign disease 1 ESGE recommends against the use of self-expandable stents (SEMSs) as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and costs (strong recommendation, low quality evidence). 2 ESGE suggests consideration of temporary placement of SEMSs as therapy for refractory benign esophageal strictures (weak recommendation, moderate evidence). Stents should usually be removed at a maximum of 3 months (strong recommendation, weak quality evidence). 3 ESGE suggests that fully covered SEMSs be preferred over partially covered SEMSs for the treatment of refractory benign esophageal strictures, because of their lack of embedment and ease of removability (weak recommendation, low quality evidence). 4 For the removal of partially covered esophageal SEMSs that are embedded, ESGE recommends the stent-in-stent technique (strong recommendation, low quality evidence). 5 ESGE recommends that temporary stent placement can be considered for treating esophageal leaks, fistulas, and perforations. The optimal stenting duration remains unclear and should be individualized. (Strong recommendation, low quality evidence.) 6 ESGE recommends placement of a SEMS for the treatment of esophageal variceal bleeding refractory to medical, endoscopic, and/or radiological therapy, or as initial therapy for patients with massive esophageal variceal bleeding (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

The medical information on the Internet is better in English than in other languages. The information about Epidural Analgesia In Labour (EAIL) available on French-speaking websites is of poor quality. The quality of the information about EAIL should be better in English, but there is no comparison available. This study has assessed and compared the quality of the information about EAIL available on French and English-speaking websites. Keywords "epidural", "épidurale" and/or "péridurale" were used in the French, Canadian and American Google ® and Yahoo ® search engines. Two independent assessors assessed the 20 first websites for each engine search. They used an evaluation form created from French, Canadian and American recommendations. This form assessed the structure quality (Structure Score/25) and the medical information quality (Medical Information Score/30) of the websites. The addition of both scores gives the Global Score (/55). Seventy-one websites were assessed, 39 French-speaking and 32 English-speaking websites. Structure, Medical Information and Global Scores (expressed as mean (SD)) were respectively 11 (4), 13 (5), 24 (8) for the French-speaking websites and 11 (4), 12 (4), 23 (7) for the English-speaking websites. There was no statistical significant difference between both languages. Information about EAIL available on French and English-speaking websites is of poor quality and there is no difference in the information quality, whatever the language. A consideration on Internet medical information improvement is needed. A high quality dedicated website should be created and broadcasted.

Blizniuk, Anastasiya; Furukawa, Sayaka; Ueno, Masayuki; Kawaguchi, Yoko
2016-01-01
To evaluate the quality of patient-oriented online information about dental caries using existing consumer evaluation tools and to judge the efficacy of these tools in quality assessment. The websites for the evaluation were pooled by using two general search engines (Google and Yahoo!). The search terms were: 'dental caries', 'tooth decay' and 'tooth cavity'. Three assessment tools (LIDA, DISCERN and FRES) were used to evaluate the quality of the information in the areas of accessibility, usability, reliability and readability. In total, 77 websites were analysed. The median scores of LIDA accessibility and usability were 45.0 and 8.0, respectively, which corresponded to a medium level of quality. The median reliability scores for LIDA (12.0) and DISCERN (20.0) both corresponded to low level of quality. The readability was high with the median FRES score 59.7. The websites on caries had good accessibility, usability and readability, while reliability of the information was poor. The LIDA instrument was found to be more convenient than DISCERN and can be recommended to lay people for quick quality assessment.

The Space Transportation Engine Program (STEP) Phase 2 effort includes preliminary design and activities plan preparation that will allow smooth and time transition into a Prototype Phase and then into Phases 3, 4, and 5. A Concurrent Engineering approach using Total Quality Management (TQM) techniques, is being applied to define an oxygen-hydrogen engine. The baseline from Phase 1/1' studies was used as a point of departure for trade studies and analyses. Existing STME system models are being enhanced as more detailed module/component characteristics are determined. Preliminary designs for the open expander, closed expander, and gas generator cycles were prepared, and recommendations for cycle selection made at the Design Concept Review (DCR). As a result of July '90 DCR, and information subsequently supplied to the Technical Review Team, a gas generator cycle was selected. Results of the various Advanced Development Programs (ADP's) for the Advanced Launch Systems (ALS) were contributive to this effort. An active vehicle integration effort is supplying the NASA, Air Force, and vehicle contractors with engine parameters and data, and flowing down appropriate vehicle requirements. Engine design and analysis trade studies are being documented in a data base that was developed and is being used to organize information. To date, seventy four trade studies were input to the data base.

In March of 1990, the NASA Administrator asked the Academy to perform a study to address the following questions: (1) has NASA contracted too much of its technical work; (2) has NASA's in-house technical capability eroded over time; (3) is in-house engineering and scientific work important to the development of scientists and engineers; and (4) is NASA still able to attract quality scientists and engineers. A panel from the Academy addressed each question separately and came up with the following recommendations: (1) prepare and issue guidance on technical functional areas reserved for in-house performance; (2) convert contracted technical functions to in-house performance if critical to agency programs; (3) provide policy guidance to the centers to retain in-house projects; (4) examine the project mix at each center against agency goals and objectives; (5) institute an annual critical review for all technical disciplines; (6) modify the agency's contractor accountability process; and (7) seek opportunities for greater delegation of resources and technical decision making.

Gujarat state in Western India exemplifies all challenges of an agrarian economy founded on groundwater overexploitation sustained over decades by perverse energy subsidies. Major consequences are: secular decline in groundwater levels, deterioration of groundwater quality, rising energy cost of pumping, soaring carbon footprint of agriculture and growing financial burden of energy subsidies. In 2009, Government of Gujarat asked the present author, an economist, to chair a Taskforce of senior hydro-geologists and civil engineers to develop and recommend a Managed Aquifer Recharge (MAR) strategy for the state. This paper summarizes the recommended strategy and its underlying logic. It also describes the imperfect fusion of socio-economic and hydro-geologic perspectives that occurred in course of the working of the Taskforce and highlights the need for trans-disciplinary perspectives on groundwater governance.
Metal-on-Metal Total Hip Arthroplasty: Quality of Online Patient Information.
Crozier-Shaw, Geoff; Queally, Joseph M; Quinlan, John F
2017-03-01
Metal-on-metal total hip arthroplasty (THA) has generated much attention in the media because of early failure of certain implant systems. This study assessed the quality, accuracy, and readability of online information on metal-on-metal THA. The search terms "metal-on-metal hip replacement" and "metal hip replacement" were entered into the 3 most popular search engines. Information quality was assessed with the DISCERN score and a specific metal-on-metal THA content score. Accuracy of information was assessed with a customized score. Readability of the websites was assessed with the Flesch-Kincaid grade level score. A total of 61 unique websites were assessed. For 56% of websites, the target audience was patients. Media or medicolegal sources accounted for 44% of websites. As assessed by DISCERN (range, 16-80) and metal-on-metal THA (range, 0-25) scores, quality of the websites was moderate at best (47.1 and 9.6, respectively). Accuracy (range, 0-8) of the information presented also was moderate, with a mean score of 6.6. Media and medicolegal websites had the lowest scores for both quality and accuracy, despite making up the greatest proportion of sites assessed. Only 1 website (2%) had a Flesch-Kincaid grade level at or less than the recommended level of 8th grade. This study found that online information on metal-on-metal THA was of poor quality, often was inaccurate, and was presented at an inappropriately high reading level, particularly for media and medicolegal websites. Health care providers should counsel patients on the quality of information available and recommend appropriate online resources. [Orthopedics. 2017; 40(2):e262-e268.].

Impact of quality of evidence on the strength of recommendations: an empirical study
Djulbegovic, Benjamin; Trikalinos, Thomas A; Roback, John; Chen, Ren; Guyatt, Gordon
2009-01-01
Background Evidence is necessary but not sufficient for decision-making, such as making recommendations by clinical practice guideline panels. However, the fundamental premise of evidence-based medicine (EBM) rests on the assumed link between the quality of evidence and "truth" and/or correctness in making guideline recommendations. If this assumption is accurate, then the quality of evidence ought to play a key role in making guideline recommendations. Surprisingly, and despite the widespread penetration of EBM in health care, there has been no empirical research to date investigating the impact of quality of evidence on the strength of recommendations made by guidelines panels. Methods The American Association of Blood Banking (AABB) has recently convened a 12 member panel to develop clinical practice guidelines (CPG) for the use of fresh-frozen plasma (FFP) for 6 different clinical indications. The panel was instructed that 4 factors should play a role in making recommendation: quality of evidence, uncertainty about the balance between desirable (benefits) and undesirable effects (harms), uncertainty or variability in values and preferences, and uncertainty about whether the intervention represents a wise use of resources (costs). Each member of the panel was asked to make his/her final judgments on the strength of recommendation and the overall quality of the body of evidence. "Voting" was anonymous and was based on the use of GRADE (Grading quality of evidence and strength of recommendations) system, which clearly distinguishes between quality of evidence and strength of recommendations. Results Despite the fact that many factors play role in formulating CPG recommendations, we show that when the quality of evidence is higher, the probability of making a strong recommendation for or against an intervention dramatically increases. Probability of making strong recommendation was 62% when evidence is "moderate", while it was only 23% and 13% when evidence was "low" or "very low", respectively. Conclusion We report the first empirical evaluation of the relationship between quality of evidence pertinent to a clinical question and strength of the corresponding guideline recommendations. Understanding the relationship between quality of evidence and probability of making (strong) recommendation has profound implications for the science of quality measurement in health care.

Evaluating the Quality and Readability of Internet Information on Meningiomas.
Saeed, Fozia; Anderson, Ian
2017-01-01
The Internet is a highly powerful resource for patients and provides an extensive amount of information on medical conditions. It is therefore important that the information accessible is accurate, up to date, and at an appropriate comprehensive level for the general public. This article aims to evaluate the quality of patient information on meningiomas. The term meningioma was searched using the following search engines: Google, Bing, Yahoo, Ask, and AOL. The top 100 meningioma Web sites were analyzed for readability using the Flesch Reading Ease score and the Flesch-Kincaid grade level. The quality of each Web page was assessed with the DISCERN instrument and the Centers for Disease Control and Prevention (CDC) Clear Communication Index (CCI). The quality of information on the Internet on meningiomas is highly variable. The overall mean Flesch Reading Ease score was 43.1 (standard deviation = 13.3) and the mean Flesch-Kincaid grade of all the Web sites was 11.2 (standard deviation = 2.3). This finding suggests that the information is on average difficult to read. Only one Web site was at the recommended seventh-grade level and the remainder were above this grade. Only one third of the Web pages had Health On the Net Code of Conduct or The Information Standard certification and were found to be significantly of higher quality: DISCERN (P = 0.022) and CDC CCI (P = 0.027). More than 50% of the Web sites had significantly poor or average DISCERN scores and only 2 Web sites fulfilled the CDC CCI criteria. It is recommended that clinicians personally research material for their patients to be able to guide them to reliable and accurate Web sites. It is also encouraged to become Health On the Net Code of Conduct/The Information Standard certified because this may indicate information of high quality.

This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy. The first 50 web-links generated by internet searches using the five most popular search engines and the key word 'thyroidectomy' were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score. We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27-59); Lida usability, 36/54 (21-50); Lida reliability, 21/51 (4-38); and Flesch Reading Ease, 43.9 (2.6-77.6). The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

The internet is frequently used by patients for researching information regarding breast cancer. This study aims to assess the quality of these websites using validated tools. The term 'breast cancer' was searched for in 3 search engines. The top 20 results were selected, and duplicates and irrelevant websites were excluded. 26/34 websites were analysed using the DISCERN Plus tool, HONcode and the JAMA benchmarks. 46% of the websites were classed as 'excellent' when assessed with the DISCERN tool. The range of DISCERN scores was wide (range: 25-74). Nine websites were found to be HONcode certified. Seven websites complied with all four JAMA benchmarks. This study shows the quality of breast cancer information on the internet is on the whole good; however the range of quality is wide. We recommend healthcare professionals use all 3 tools together to establish which websites are best to advise which websites patients should trust. Copyright © 2015 Elsevier Ltd. All rights reserved.

Marsh, A. H.
1982-01-01
Specific recommendations for environmental test criteria, data acquisition procedures, and instrument performance requirements for measurement of noise levels produced by aircraft in flight are provided. Recommendations are also given for measurement of associated airplane and engine parameters and atmospheric conditions. Recommendations are based on capabilities which were available commercially in 1981; they are applicable to field tests of aircraft flying subsonically past microphones located near the surface of the ground either directly under or to the side of a flight path. Aircraft types covered by the recommendations include fixed-wing airplanes powered by turbojet or turbofan engines or by propellers. The recommended field-measurement procedures are consistent with assumed requirements for data processing and analysis.

Information available on the Internet about immunizations may influence parents' perception about human papillomavirus (HPV) immunization and their attitude toward vaccinating their daughters. We hypothesized that the quality of information on HPV available on the Internet may vary with language and with the level of knowledge of parents. To this end we compared the quality of a sample of Web pages in Italian with a sample of Web pages in English. Five reviewers assessed the quality of Web pages retrieved with popular search engines using criteria adapted from the Good Information Practice Essential Criteria for Vaccine Safety Web Sites recommended by the World Health Organization. Quality of Web pages was assessed in the domains of accessibility, credibility, content, and design. Scores in these domains were compared through nonparametric statistical tests. We retrieved and reviewed 74 Web sites in Italian and 117 in English. Most retrieved Web pages (33.5%) were from private agencies. Median scores were higher in Web pages in English compared with those in Italian in the domain of accessibility (p < .01), credibility (p < .01), and content (p < .01). The highest credibility and content scores were those of Web pages from governmental agencies or universities. Accessibility scores were positively associated with content scores (p < .01) and with credibility scores (p < .01). A total of 16.2% of Web pages in Italian opposed HPV immunization compared with 6.0% of those in English (p < .05). Quality of information and number of Web pages opposing HPV immunization may vary with the Web site language. High-quality Web pages on HPV, especially from public health agencies and universities, should be easily accessible and retrievable with common Web search engines.

Incident-response monitoring technologies for aircraft cabin air quality
NASA Astrophysics Data System (ADS)
Magoha, Paul W.
Poor air quality in commercial aircraft cabins can be caused by volatile organophosphorus (OP) compounds emitted from the jet engine bleed air system during smoke/fume incidents. Tri-cresyl phosphate (TCP), a common anti-wear additive in turbine engine oils, is an important component in today's global aircraft operations. However, exposure to TCP increases risks of certain adverse health effects. This research analyzed used aircraft cabin air filters for jet engine oil contaminants and designed a jet engine bleed air simulator (BAS) to replicate smoke/fume incidents caused by pyrolysis of jet engine oil. Field emission scanning electron microscopy (FESEM) with X-ray energy dispersive spectroscopy (EDS) and neutron activation analysis (NAA) were used for elemental analysis of filters, and gas chromatography interfaced with mass spectrometry (GC/MS) was used to analyze used filters to determine TCP isomers. The filter analysis study involved 110 used and 90 incident filters. Clean air filter samples exposed to different bleed air conditions simulating cabin air contamination incidents were also analyzed by FESEM/EDS, NAA, and GC/MS. Experiments were conducted on a BAS at various bleed air conditions typical of an operating jet engine so that the effects of temperature and pressure variations on jet engine oil aerosol formation could be determined. The GC/MS analysis of both used and incident filters characterized tri- m-cresyl phosphate (TmCP) and tri-p-cresyl phosphate (TpCP) by a base peak of an m/z = 368, with corresponding retention times of 21.9 and 23.4 minutes. The hydrocarbons in jet oil were characterized in the filters by a base peak pattern of an m/z = 85, 113. Using retention times and hydrocarbon thermal conductivity peak (TCP) pattern obtained from jet engine oil standards, five out of 110 used filters tested had oil markers. Meanwhile 22 out of 77 incident filters tested positive for oil fingerprints. Probit analysis of jet engine oil aerosols obtained from BAS tests by optical particle counter (OPC) revealed lognormal distributions with the mean (range) of geometric mass mean diameter (GMMD) = 0.41 (0.39, 0.45) microm and geometric standard deviation (GSD), sigma g = 1.92 (1.87, 1.98). FESEM/EDS and NAA techniques found a wide range of elements on filters, and further investigations of used filters are recommended using these techniques. The protocols for air and filter sampling and GC/MS analysis used in this study will increase the options available for detecting jet engine oil on cabin air filters. Such criteria could support policy development for compliance with cabin air quality standards during incidents.

The risk of endoscopy in patients on antithrombotics depends on the risks of procedural haemorrhage vs. thrombosis due to discontinuation of therapy. P2Y12 receptor antagonists (clopidogrel, prasugrel, ticagrelor): For low-risk endoscopic procedures we recommend continuing P2Y12 receptor antagonists as single or dual antiplatelet therapy (low quality evidence, strong recommendation);For high-risk endoscopic procedures in patients at low thrombotic risk, we recommend discontinuing P2Y12 receptor antagonists five days before the procedure (moderate quality evidence, strong recommendation). In patients on dual antiplatelet therapy, we suggest continuing aspirin (low quality evidence, weak recommendation).For high-risk endoscopic procedures in patients at high thrombotic risk, we recommend continuing aspirin and liaising with a cardiologist about the risk/benefit of discontinuation of P2Y12 receptor antagonists (high quality evidence, strong recommendation). Warfarin: The advice for warfarin is fundamentally unchanged from BSG 2008 guidance. Direct Oral Anticoagulants (DOAC): For low-risk endoscopic procedures we suggest omitting the morning dose of DOAC on the day of the procedure (very low quality evidence, weak recommendation). For high-risk endoscopic procedures, we recommend that the last dose of DOAC be taken ≥ 48 hours before the procedure (very low quality evidence, strong recommendation). For patients on dabigatran with CrCl (or estimated glomerular filtration rate, eGFR) of 30 - 50 mL/min we recommend that the last dose of DOAC be taken 72 hours before the procedure (very low quality evidence, strong recommendation). In any patient with rapidly deteriorating renal function a haematologist should be consulted (low quality evidence, strong recommendation). © Georg Thieme Verlag KG Stuttgart · New York.

Personalized drug prescription can be benefited from the use of intelligent information management and sharing. International standard classifications and terminologies have been developed in order to provide unique and unambiguous information representation. Such standards can be used as the basis of automated decision support systems for providing drug-drug and drug-disease interaction discovery. Additionally, Semantic Web technologies have been proposed in earlier works, in order to support such systems. The paper presents Panacea, a semantic framework capable of offering drug-drug and drug-diseases interaction discovery. For enabling this kind of service, medical information and terminology had to be translated to ontological terms and be appropriately coupled with medical knowledge of the field. International standard classifications and terminologies, provide the backbone of the common representation of medical data while the medical knowledge of drug interactions is represented by a rule base which makes use of the aforementioned standards. Representation is based on a lightweight ontology. A layered reasoning approach is implemented where at the first layer ontological inference is used in order to discover underlying knowledge, while at the second layer a two-step rule selection strategy is followed resulting in a computationally efficient reasoning approach. Details of the system architecture are presented while also giving an outline of the difficulties that had to be overcome. Panacea is evaluated both in terms of quality of recommendations against real clinical data and performance. The quality recommendation gave useful insights regarding requirements for real world deployment and revealed several parameters that affected the recommendation results. Performance-wise, Panacea is compared to a previous published work by the authors, a service for drug recommendations named GalenOWL, and presents their differences in modeling and approach to the problem, while also pinpointing the advantages of Panacea. Overall, the paper presents a framework for providing an efficient drug recommendations service where Semantic Web technologies are coupled with traditional business rule engines.

Automobile engine coolant liquids are commonly used for efficient heat transfer from the engine to the surroundings. In this work we have investigated the thermal diffusivity of various commonly available engine coolants in Indian automobile market. We have used single beam laser induced thermal lens technique for the measurements. Engine coolants are generally available in concentrated solution form and are recommended to use at specified dilution. We have investigated the samples in the entire recommended concentration range for the use in radiators. While some of the brands show an enhanced thermal diffusivity compared to pure water, others show slight decrease in thermal diffusivity.

Criteria for determining the quality of liver sediment are necessary to ensure that concentrations of contaminants in aquatic systems are within acceptable limits for the protection of aquatic and human life. Such criteria should facilitate decision-making about remediation, handling, and disposal of contaminants. Several approaches to the development of sediment quality criteria (SQC) have been described and include both descriptive and numerical methods. However, no single method measures all impacts at all times to all organisms (U.S. EPA 1992b). The U.S. EPA`s interest is primarily in establishing chemically based, numerical SQC that are applicable nation-wide (Shea 1988). Of the approachesmore » proposed for SQC development, only three are being considered for numerical SQC on a national level. These approaches include an Equilibrium Partitioning Approach, a site-specific method using bioassays (the Apparent Effects Threshold Approach), and an approach similar to EPA`s water quality criteria (Pavlou and Weston 1984). Although national (or even regional) criteria address a number of political, litigative, and engineering needs, some researchers feel that protection of benthic communities require site-specific, biologically based criteria (Baudo et al. 1990). This is particularly true for areas where complex mixtures of contaminants are present in sediments. Other scientifically valid and accepted procedures for freshwater SQC include a background concentration approach, methods using field or spiked bioassays, a screening level concentration approach, the Apparent Effects Threshold Approach, the Sediment Quality Triad, the International Joint Commission Sediment Assessment Strategy, and the National Status and Trends Program Approach. The various sediment assessment approaches are evaluated for application to the Hanford Reach and recommendations for Hanford Site sediment quality criteria are discussed.« less

1: ESGE suggests using contrast-enhanced computed tomography (CT) as the first-line imaging modality on admission when indicated and up to the 4th week from onset in the absence of contraindications. Magnetic resonance imaging (MRI) may be used instead of CT in patients with contraindications to contrast-enhanced CT, and after the 4th week from onset when invasive intervention is considered because the contents (liquid vs. solid) of pancreatic collections are better characterized by MRI and evaluation of pancreatic duct integrity is possible. Weak recommendation, low quality evidence. 2: ESGE recommends against routine percutaneous fine needle aspiration (FNA) of (peri)pancreatic collections. Strong recommendation, moderate quality evidence. FNA should be performed only if there is suspicion of infection and clinical/imaging signs are unclear. Weak recommendation, low quality evidence. 3: ESGE recommends initial goal-directed intravenous fluid therapy with Ringer's lactate (e. g. 5 - 10 mL/kg/h) at onset. Fluid requirements should be patient-tailored and reassessed at frequent intervals. Strong recommendation, moderate quality evidence. 4: ESGE recommends against antibiotic or probiotic prophylaxis of infectious complications in acute necrotizing pancreatitis. Strong recommendation, high quality evidence. 5: ESGE recommends invasive intervention for patients with acute necrotizing pancreatitis and clinically suspected or proven infected necrosis. Strong recommendation, low quality evidence.ESGE suggests that the first intervention for infected necrosis should be delayed for 4 weeks if tolerated by the patient. Weak recommendation, low quality evidence. 6: ESGE recommends performing endoscopic or percutaneous drainage of (suspected) infected walled-off necrosis as the first interventional method, taking into account the location of the walled-off necrosis and local expertise. Strong recommendation, moderate quality evidence. 7: ESGE suggests that, in the absence of improvement following endoscopic transmural drainage of walled-off necrosis, endoscopic necrosectomy or minimally invasive surgery (if percutaneous drainage has already been performed) is to be preferred over open surgery as the next therapeutic step, taking into account the location of the walled-off necrosis and local expertise. Weak recommendation, low quality evidence. 8: ESGE recommends long-term indwelling of transluminal plastic stents in patients with disconnected pancreatic duct syndrome. Strong recommendation, low quality evidence. Lumen-apposing metal stents should be retrieved within 4 weeks to avoid stent-related adverse effects.Strong recommendation, low quality evidence. © Georg Thieme Verlag KG Stuttgart · New York.

To quantify the effect of a new continuous-care guideline (GL)-application engine, the Picard decision support system (DSS) engine, on the correctness and completeness of clinicians' decisions relative to an established clinical GL, and to assess the clinicians' attitudes towards a specific DSS. Thirty-six clinicians, including residents at different training levels and board-certified specialists at an academic OB/GYN department that handles around 15,000 deliveries annually, agreed to evaluate our continuous-care guideline-based DSS and to perform a cross-over assessment of the effects of using our guideline-based DSS. We generated electronic patient records that realistically simulated the longitudinal course of six different clinical scenarios of the preeclampsia/eclampsia/toxemia (PET) GL, encompassing 60 different decision points in total. Each clinician managed three scenarios manually without the Picard DSS engine (Non-DSS mode) and three scenarios when assisted by the Picard DSS engine (DSS mode). The main measures in both modes were correctness and completeness of actions relative to the PET GL. Correctness was further decomposed into necessary and redundant actions, relative to the guideline and the actual patient data. At the end of the assessment, a questionnaire was administered to the clinicians to assess their perceptions regarding use of the DSS. With respect to completeness, the clinicians applied approximately 41% of the GL's recommended actions in the non-DSS mode. Completeness increased to the performance of approximately 93% of the guideline's recommended actions, when using the DSS mode. With respect to correctness, approximately 94.5% of the clinicians' decisions in the non-DSS mode were correct. However, these included 68% of the actions that were correct but redundant, given the patient's data (e.g., repeating tests that had been performed), and 27% of the actions, which were necessary in the context of the GL and of the given scenario. Only 5.5% of the decisions were definite errors. In the DSS mode, 94% of the clinicians' decisions were correct, which included 3% that were correct but redundant, and 91% of the actions that were correct and necessary in the context of the GL and of the given scenario. Only 6% of the DSS-mode decisions were erroneous. The DSS was assessed by the clinicians as potentially useful. Support from the GL-based DSS led to uniformity in the quality of the decisions, regardless of the particular clinician, any particular clinical scenario, any particular decision point, or any decision type within the scenarios. Using the DSS dramatically enhances completeness (i.e., performance of guideline-based recommendations) and seems to prevent the performance of most of the redundant actions, but does not seem to affect the rate of performance of incorrect actions. The redundancy rate is enhanced by similar recent findings in recent studies. Clinicians mostly find this support to be potentially useful for their daily practice. A continuous-care GL-based DSS, such as the Picard DSS engine, has the potential to prevent most errors of omission by ensuring uniformly high quality of clinical decision making (relative to a GL-based norm), due to the increased adherence (i.e., completeness) to the GL, and most of the errors of commission that increase therapy costs, by reducing the rate of redundant actions. However, to prevent clinical errors of commission, the DSS needs to be accompanied by additional modules, such as automated control of the quality of the physician's actual actions.

This paper presents a system management methodology for building successful resource management systems that possess lifecycle effectiveness. This methodology is based on an analysis of the traditional practice of Systems Engineering Management as it applies to the development of resource management systems. The analysis produced fifteen significant findings presented as recommended adaptations to the traditional practice of Systems Engineering Management to accommodate system development when the requirements are incomplete, unquantifiable, ambiguous and dynamic. Ten recommended adaptations to achieve operational effectiveness when requirements are incomplete, unquantifiable or ambiguous are presented and discussed. Five recommended adaptations to achieve system extensibility when requirements are dynamic are also presented and discussed. The authors conclude that the recommended adaptations to the traditional practice of Systems Engineering Management should be implemented for future resource management systems and that the technology exists to build these systems extensibly.

Objectives Identification of sufficiently trustworthy top 5 list recommendations from the US Choosing Wisely campaign. Setting Not applicable. Participants All top 5 list recommendations available from the American Board of Internal Medicine Foundation website. Main outcome measures/interventions Compilation of US top 5 lists and search for current German highly trustworthy (S3) guidelines. Extraction of guideline recommendations, including grade of recommendation (GoR), for suggestions comparable to top 5 list recommendations. For recommendations without guideline equivalents, the methodological quality of the top 5 list development process was assessed using criteria similar to that used to judge guidelines, and relevant meta-literature was identified in cited references. Judgement of sufficient trustworthiness of top 5 list recommendations was based either on an ‘A’ GoR of guideline equivalents or on high methodological quality and citation of relevant meta-literature. Results 412 top 5 list recommendations were identified. For 75 (18%), equivalents were found in current German S3 guidelines. 44 of these recommendations were associated with an ‘A’ GoR, or a strong recommendation based on strong evidence, and 26 had a ‘B’ or a ‘C’ GoR. No GoR was provided for 5 recommendations. 337 recommendations had no equivalent in the German S3 guidelines. The methodological quality of the development process was high and relevant meta-literature was cited for 87 top 5 list recommendations. For a further 36, either the methodological quality was high without any meta-literature citations or meta-literature citations existed but the methodological quality was lacking. For the remaining 214 recommendations, either the methodological quality was lacking and no literature was cited or the methodological quality was generally unsatisfactory. Conclusions 131 of current US top 5 list recommendations were found to be sufficiently trustworthy. For a substantial number of current US top 5 list recommendations, their trustworthiness remains unclear. Methodological requirements for developing top 5 lists are recommended. PMID:27855098

This report highlights the drivers, challenges, and enablers of the hybrid modeling applications in biopharmaceutical industry. It is a summary of an expert panel discussion of European academics and industrialists with relevant scientific and engineering backgrounds. Hybrid modeling is viewed in its broader sense, namely as the integration of different knowledge sources in form of parametric and nonparametric models into a hybrid semi-parametric model, for instance the integration of fundamental and data-driven models. A brief description of the current state-of-the-art and industrial uptake of the methodology is provided. The report concludes with a number of recommendations to facilitate further developments and a wider industrial application of this modeling approach. These recommendations are limited to further exploiting the benefits of this methodology within process analytical technology (PAT) applications in biopharmaceutical industry.

Enhancing the Human Factors Engineering Role in an Austere Fiscal Environment
NASA Technical Reports Server (NTRS)
Stokes, Jack W.
2003-01-01
An austere fiscal environment in the aerospace community creates pressures to reduce program costs, often minimizing or sometimes even deleting the human interface requirements from the design process. With an assumption that the flight crew can recover real time from a poorly human factored space vehicle design, the classical crew interface requirements have been either not included in the design or not properly funded, though carried as requirements. Cost cuts have also affected quality of retained human factors engineering personnel. In response to this concern, planning is ongoing to correct the acting issues. Herein are techniques for ensuring that human interface requirements are integrated into a flight design, from proposal through verification and launch activation. This includes human factors requirements refinement and consolidation across flight programs; keyword phrases in the proposals; closer ties with systems engineering and other classical disciplines; early planning for crew-interface verification; and an Agency integrated human factors verification program, under the One NASA theme. Importance is given to communication within the aerospace human factors discipline, and utilizing the strengths of all government, industry, and academic human factors organizations in an unified research and engineering approach. A list of recommendations and concerns are provided in closing.

This manuscript presents evidence-based guidance on the use of vital pulp therapies for treatment of deep caries lesions in children. A guideline panel convened by the American Academy of Pediatric Dentistry formulated evidence-based recommendations on three vital pulp therapies: indirect pulp treatment (IPT; also known as indirect pulp cap), direct pulp cap (DPC), and pulpotomy. The basis of the guideline's recommendations was evidence from "Primary Tooth Vital Pulp Therapy: A Systematic Review and Meta-Analysis." (Pediatr Dent 2017;15;39[1]:16-23.) A systematic search was conducted in PubMed®/MEDLINE, Embase®, Cochrane Central Register of Controlled Trials, and trial databases to identify randomized controlled trials and systematic reviews addressing peripheral issues of vital pulp therapies such as patient preferences of treatment and impact of cost. Quality of the evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation approach; the evidence-to-decision framework was used to formulate a recommendation. The panel was unable to make a recommendation on superiority of any particular type of vital pulp therapy owing to lack of studies directly comparing these interventions. The panel recommends use of mineral trioxide aggregate (MTA) and formocresol in pulpotomy treatments; these are recommendations based on moderate-quality evidence at 24 months. The panel made weak recommendations regarding choice of medicament in both IPT (moderate-quality evidence [24 months], low quality evidence [48 months]) and DPC (very-low quality evidence [24 months]). Success of both treatments was independent of type of medicament used. The panel also recommends use of ferric sulfate (low-quality evidence), lasers (low-quality evidence), sodium hypochlorite (very low-quality evidence), and tricalcium silicate (very low-quality evidence) in pulpotomies; these are weak recommendations based on low-quality evidence. The panel recommended against the use of calcium hydroxide as pulpotomy medicament in primary teeth with deep caries lesions. Conclusions and practical implications: The guideline intends to inform the clinical practices with evidence-based recommendations on vital pulp therapies in primary teeth with deep caries lesions. These recommendations are based upon the best available evidence to-date.

The benefits associated with decreasing wall thicknesses below their current values are still measurable and desired even if the final wall thickness is nowhere near those of the aggressive portable electronics industry. It is important to note that gains in wall section reduction do not always occur without investment, in this case, in tooling and machinery upgrades. Equally important is the fact that productivity and performance benefits of reduced material usage, fast cycle times, and lighter weight can often outweigh most of the added costs. In order to eliminate unnecessary mould trials, minimize product development cycle, reduce overall costs and improve product quality, polymeric engineers use new CAE technology (Computer Aided Engineering). This technology is a simulation tool, which combines proven theories, material properties and process conditions to generate realistic simulations and produce valuable recommendations. Based on these recommendations, an optional combination of product design, material and process conditions can be identified. In this work, Moldex3D software was used for simulation of injection moulding in order to avoid potential moulding problems. The results gained from the simulation were used for the optimization of an existing product design, for mould development and for optimization of processing parameters, e.g. injection pressure, mould cavity temperature, etc.

Special Region of Yogyakarta (DIY) is known as city for academic. Many people come to get some education in college. They live in boarding house with some supporting facilities. The most common facilities is low table which lead students have to sit on the floor while studying on table which could cause higher risk of back pain and musculoskeletal disorder. To identify the solution to reduce back pain and musculoskeletal risk, it is needed to design a lesehan chair which also appropriate to customer needs. Kansei engineering method was used with a total of 30 respondents participated, 15 kansei words collected, and 12 kansei words selected by doing validation and reliability test. The result of this study showed that quality, aesthetics, and comfort level influence the design of lesehan chair. A design of lesehan chair was created by considering the suitable concept and merging it with the physical design and its anthropometry measurement. In this case, marginal homogeneity test is needed to identify the differences between each kansei words attribute and the design or product recommendation. The marginal homogeneity test results show that the design and product recommendation has fulfilled customer's desires and needs. For further research, it is needed to analyse and evaluate the posture of lesehan chair users in order to develop and improve its performance.

Human papillomavirus (HPV) vaccination rates fall far short of Healthy People 2020 objectives. A leading reason is that clinicians do not recommend the vaccine consistently and strongly to girls and boys in the age group recommended for vaccination. Although Web-based HPV vaccine educational interventions for clinicians have been created to promote vaccination recommendations, rigorous evaluations of these interventions have not been conducted. Such evaluations are important to maximize the efficacy of educational interventions in promoting clinician recommendations for HPV vaccination. The objectives of our study were (1) to expand previous research by systematically identifying HPV vaccine Web-based educational interventions developed for clinicians and (2) to evaluate the quality of these Web-based educational interventions as defined by access, content, design, user evaluation, interactivity, and use of theory or models to create the interventions. Current HPV vaccine Web-based educational interventions were identified from general search engines (ie, Google), continuing medical education search engines, health department websites, and professional organization websites. Web-based educational interventions were included if they were created for clinicians (defined as individuals qualified to deliver health care services, such as physicians, clinical nurses, and school nurses, to patients aged 9 to 26 years), delivered information about the HPV vaccine and how to increase vaccination rates, and provided continuing education credits. The interventions' content and usability were analyzed using 6 key indicators: access, content, design, evaluation, interactivity, and use of theory or models. A total of 21 interventions were identified, out of which 7 (33%) were webinars, 7 (33%) were videos or lectures, and 7 (33%) were other (eg, text articles, website modules). Of the 21 interventions, 17 (81%) identified the purpose of the intervention, 12 (57%) provided the date that the information had been updated (7 of these were updated within the last 6 months), 14 (67%) provided the participants with the opportunity to provide feedback on the intervention, and 5 (24%) provided an interactive component. None of the educational interventions explicitly stated that a theory or model was used to develop the intervention. This analysis demonstrates that a substantial proportion of Web-based HPV vaccine educational interventions has not been developed using established health education and design principles. Interventions designed using these principles may increase strong and consistent HPV vaccination recommendations by clinicians. ©Brittany L Rosen, James M Bishop, Skye L McDonald, Jessica A Kahn, Gary L Kreps.

The world’s first master’s degree program in nuclear safeguards and security, established at Moscow Engineering Physics Institute (MEPhI), has now graduated nine classes of students. Most of the graduates have gone on to work at government agencies, research organizations, or obtain their PhD. In order to meet the demand for safeguards and security specialists at nuclear facilities, MEPhI established a 5½ year engineering degree program that provides more hands-on training desired by facilities. In February 2004, the first students began their studies in the new discipline Nuclear Material Safeguards and Nonproliferation. This class, as well as other subsequent classes, includedmore » students who started the program in their third year of studies, as the first 2½ years consists of general engineering curriculum. Fourteen students made up the first graduating class, receiving their engineering degrees in February 2007. The topics addressed in this paper include specific features of the program caused by peculiarities of Russian education legislation and government quality control of academic education. This paper summarizes the main joint actions undertaken by MEPhI and the US National Laboratories in conjunction with the U.S. Department of Energy, to develop the engineering degree program. Also discussed are the program’s specific training requirements, student internships, and job placement. The paper concludes with recommendations from a recent international seminar on nonproliferation education and training.« less

Control of a large jet transport aircraft without the use of conventional control surfaces was studied. Engine commands were used to attempt to recreate the forces and moments typically provided by the elevator, ailerons, and rudder. Necessary conditions for aircraft controllability were developed pertaining to aircraft configuration such as the number of engines and engine placement. An optimal linear quadratic regulator controller was developed for the Boeing 707-720, in particular, for regulation of its natural dynamic modes. The design used a method of assigning relative weights to the natural modes, i.e., phugoid and dutch roll, for a more intuitive selection of the cost function. A prototype pilot command interface was then integrated into the loop based on pseudorate command of both pitch and roll. Closed loop dynamics were evaluated first with a batch linear simulation and then with a real time high fidelity piloted simulation. The NASA research pilots assisted in evaluation of closed loop handling qualities for typical cruise and landing tasks. Recommendations for improvement on this preliminary study of optimal propulsion only flight control are provided.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system 1 2 was adopted to define the strength of recommendations and the quality of evidence. 1 ESGE recommends endoscopic en bloc resection for superficial esophageal squamous cell cancers (SCCs), excluding those with obvious submucosal involvement (strong recommendation, moderate quality evidence). Endoscopic mucosal resection (EMR) may be considered in such lesions when they are smaller than 10 mm if en bloc resection can be assured. However, ESGE recommends endoscopic submucosal dissection (ESD) as the first option, mainly to provide an en bloc resection with accurate pathology staging and to avoid missing important histological features (strong recommendation, moderate quality evidence). 2 ESGE recommends endoscopic resection with a curative intent for visible lesions in Barrett's esophagus (strong recommendation, moderate quality evidence). ESD has not been shown to be superior to EMR for excision of mucosal cancer, and for that reason EMR should be preferred. ESD may be considered in selected cases, such as lesions larger than 15 mm, poorly lifting tumors, and lesions at risk for submucosal invasion (strong recommendation, moderate quality evidence). 3 ESGE recommends endoscopic resection for the treatment of gastric superficial neoplastic lesions that possess a very low risk of lymph node metastasis (strong recommendation, high quality evidence). EMR is an acceptable option for lesions smaller than 10 - 15 mm with a very low probability of advanced histology (Paris 0-IIa). However, ESGE recommends ESD as treatment of choice for most gastric superficial neoplastic lesions (strong recommendation, moderate quality evidence). 4 ESGE states that the majority of colonic and rectal superficial lesions can be effectively removed in a curative way by standard polypectomy and/or by EMR (strong recommendation, moderate quality evidence). ESD can be considered for removal of colonic and rectal lesions with high suspicion of limited submucosal invasion that is based on two main criteria of depressed morphology and irregular or nongranular surface pattern, particularly if the lesions are larger than 20 mm; or ESD can be considered for colorectal lesions that otherwise cannot be optimally and radically removed by snare-based techniques (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Recommender systems play an essential role in the modern business world. They recommend favorable items such as books, movies, and search queries to users based on their past preferences. Applying similar ideas and techniques to Monte Carlo simulations of physical systems boosts their efficiency without sacrificing accuracy. Exploiting the quantum to classical mapping inherent in the continuous-time quantum Monte Carlo methods, we construct a classical molecular gas model to reproduce the quantum distributions. We then utilize powerful molecular simulation techniques to propose efficient quantum Monte Carlo updates. The recommender engine approach provides a general way to speed up the quantum impurity solvers.

The technique of digital image correlation (DIC), which has been widely used for noncontact deformation measurements in both the scientific and engineering fields, is greatly affected by the quality of speckle patterns in terms of its performance. This study was concerned with the optimization of the digital speckle pattern (DSP) for DIC in consideration of both the accuracy and efficiency. The root-mean-square error of the inverse compositional Gauss-Newton algorithm and the average number of iterations were used as quality metrics. Moreover, the influence of subset sizes and the noise level of images, which are the basic parameters in the quality assessment formulations, were also considered. The simulated binary speckle patterns were first compared with the Gaussian speckle patterns and captured DSPs. Both the single-radius and multi-radius DSPs were optimized. Experimental tests and analyses were conducted to obtain the optimized and recommended DSP. The vector diagram of the optimized speckle pattern was also uploaded as reference.

A readability and quality control Internet-based study using recognized quality scoring systems. To assess the readability and quality of Internet information relating to cauda equina syndrome accessed through common search engines. Access to health-related Internet information has increased dramatically during the past decade. A significant proportion of this information has been demonstrated to be set at too high a level for general comprehension. Despite this, searching for health-related information is now the third most popular online activity. A total of 125 cauda equina syndrome Web sites were analyzed from the 5 most popular Internet search engines: Google, Bing, Yahoo, Ask, and AOL. Web site authorship was classified: academic, physician, medico-legal, commercial, or discussion/social media. Readability of each Web site was assessed using the Flesch Reading Ease score, the Flesch-Kincaid grade level, and the Gunning Fog Index. Quality was calculated using the DISCERN instrument and The Journal of the American Medical Association benchmark criteria. The presence of HON-code certification was also assessed. Fifty-two individual Web sites were identified and assessed. The majority of Web sites were academic or physician compiled (53.8%; 28/52); however, a significant minority of Web sites were medico-legal related (19.2%; 10/52). Just 13.5% (7/52) of Web sites were at or below the recommended sixth-grade readability level. HON-code certified Web sites achieved significantly greater DISCERN (P = 0.0006) and The Journal of the American Medical Association (P = 0.0002) scores. Internet information relating to cauda equina syndrome is of variable quality and largely set at an inappropriate readability level. Given this variability in quality, health care providers should direct patients to known sources of reliable, readable online information. Identification of reliable sources may be aided by known markers of quality such as HON-code certification.

Many osteoporosis clinical practice guidelines are published, and the extent to which physical activity and safe movement is addressed varies. To better inform clinical decision-making, a quality assessment and structured analysis of recommendations was undertaken. Guideline quality varied substantially, and improvement is necessary in physical activity and safe movement recommendations. The purpose of the present study is to survey available osteoporosis clinical practice guidelines (CPGs) containing physical activity and safe movement recommendations in order to assess the methodological quality with which they were developed. An analysis of the various physical activity and safe movement recommendations was conducted to determine variability between CPGs. An online literature search revealed 19 CPGs meeting our inclusion criteria. Three independent scorers evaluated CPG quality using the Appraisal of Guidelines for Research and Evaluation version II (AGREE II) instrument. Two separate individuals used a standard table to extract relevant recommendations. Intra-reviewer AGREE II score agreement ranged from fair to good (intra-class correlation coefficient (ICC) = 0.34 to 0.65). The quality of the 19 included CPGs was variable (AGREE sub-scores: 14 to 100%). CPGs scored higher in the "scope and purpose" and "clarity of presentation" domains. They scored the lowest in "applicability" and "editorial independence." Four CPGs were classified as high quality, ten average quality, and five low quality. Most CPGs recommended weight-bearing, muscle-strengthening, and resistance exercises. Information on exercise dosage, progression, and contraindications was often absent. Immobility and movements involving spinal flexion and/or torsion were discouraged. There were several high-quality CPGs; however, variability in quality and lack of specific parameters for implementation necessitates caution and critical examination by readers. CPG development groups should pay special attention to the clinical applicability of their CPGs as well as fully disclosing conflicts of interest. CPGs were in general an agreement regarding safe physical activity and safe movement recommendations. However, recommendations were often vague and the more specific recommendations were inconsistent between CPGs.

Adequate military communications are essential to the security of the United States, especially in the various stages of major wars. Enough communications must survive to make effective use of our military forces and weaponry, even in the face of a concerted enemy effort to destroy those communications. An evolutionary approach to provide survivability is recommended. It must be provided by the design engineer. Afterthought and modification must be replaced with foresight and design. The engineer must make survivability a criterion in every design decision. The design engineer needs help with the challenges and associated details of successfully accomplishing this. The author discusses and recommends development of convenient-to-use survivability engineering design tools to provide this help.

This study aimed to assess the quality and accuracy of nutrition information about cancer prevention available on the Web. The keywords 'nutrition + diet + cancer + prevention' were submitted to the Google search engine. Out of 400 websites evaluated, 100 met the inclusion and exclusion criteria and were selected as the sample for the assessment of quality and accuracy. Overall, 54% of the studied websites had low quality, 48 and 57% had no author's name or information, respectively, 100% were not updated within 1 month during the study period and 86% did not have the Health on the Net seal. When the websites were assessed for readability using the Flesch Reading Ease test, nearly 44% of the websites were categorised as 'quite difficult'. With regard to accuracy, 91% of the websites did not precisely follow the latest WCRF/AICR 2007 recommendation. The quality scores correlated significantly with the accuracy scores (r = 0.250, p < 0.05). Professional websites (n = 22) had the highest mean quality scores, whereas government websites (n = 2) had the highest mean accuracy scores. The quality of the websites selected in this study was not satisfactory, and there is great concern about the accuracy of the information being disseminated.

Measurements underpin the engineering decisions that allow products to be designed, manufactured, operated, and maintained. Therefore, the quality of measured data needs to be systematically assured to allow decision makers to proceed with confidence. The use of standards is one way of achieving this. This paper explores the relevance of international documentary standards to the assessment of measurement system capability in High Value Manufacturing (HVM) Industry. An internal measurement standard is presented which supplements these standards and recommendations are made for a cohesive effort to develop the international standards to provide consistency in such industrial applications.

The American Society for Colposcopy and Cervical Pathology (ASCCP) Colposcopy Standards recommendations address the role of and approach to colposcopy and biopsy for cervical cancer prevention in the United States. The recommendations were developed by an expert working group appointed by ASCCP's Board of Directors. The ASCCP Quality Improvement Working Group developed evidence-based guidelines to promote best practices and reduce errors in colposcopy and recommended indicators to measure colposcopy quality. The working group performed a systematic review of existing major society and national guidelines and quality indicators. An initial list of potential quality indicators was developed and refined through successive iterative discussions, and draft quality indicators were proposed. The draft recommendations were then reviewed and commented on by the entire Colposcopy Standards Committee, posted online for public comment, and presented at the International Federation for Cervical Pathology and Colposcopy 2017 World Congress for further comment. All comments were considered, additional adjustments made, and the final recommendations approved by the entire Task Force. Eleven quality indicators were selected spanning documentation, biopsy protocols, and time intervals between index screening tests and completion of diagnostic evaluation. The proposed quality indicators are intended to serve as a starting point for quality improvement in colposcopy at a time when colposcopy volume is decreasing and individual procedures are becoming technically more difficult to perform.

The Internet provides consumers with access to online health information; however, identifying relevant and valid information can be problematic. Our objectives were firstly to investigate the efficiency of search-engines, and then to assess the quality of online information pertaining to androgen deficiency in the ageing male (ADAM). Keyword searches were performed on nine search-engines (four general and five medical) to identify website information regarding ADAM. Search-engine efficiency was compared by percentage of relevant websites obtained via each search-engine. The quality of information published on each website was assessed using the DISCERN rating tool. Of 4927 websites searched, 47 (1.44%) and 10 (0.60%) relevant websites were identified by general and medical search-engines respectively. The overall quality of online information on ADAM was poor. The quality of websites retrieved using medical search-engines did not differ significantly from those retrieved by general search-engines. Despite the poor quality of online information relating to ADAM, it is evident that medical search-engines are no better than general search-engines in sourcing consumer information relevant to ADAM.

Improving the quality of physicians' recommendations for human papillomavirus (HPV) vaccination is critical to addressing low coverage. Thus, we sought to describe HPV vaccine communication practices among primary care physicians. Pediatricians and family physicians (n = 776) completed our national online survey in 2014. We assessed the quality of their HPV vaccine recommendations on strength of endorsement (i.e., saying the vaccine is important), timeliness (recommending it by ages 11-12), consistency (recommending it routinely vs. using a risk-based approach), and urgency (recommending same-day vaccination). A sizeable minority of physicians reported that they do not strongly endorse HPV vaccine (27%) or deliver timely recommendations for girls (26%) or boys (39%). Many physicians (59%) used a risk-based approach to recommending HPV vaccine, and only half (51%) usually recommended same-day vaccination. Overall recommendation quality was lower among physicians who were uncomfortable talking about HPV vaccine or who believed parents did not value it. Quality was higher among physicians who began discussions by saying the child was due for HPV vaccine versus giving information or eliciting questions. Many physicians in our national sample reported recommending HPV vaccine inconsistently, behind schedule, or without urgency. These practices likely contribute to under-immunization among adolescents, and may convey ambivalence to parents. As one of the first studies to assess multiple aspects of recommendation quality, these findings can inform the many state and national initiatives that aim to improve communication about HPV vaccine so as to address the persistent underuse of a powerful tool for cancer prevention. ©2015 American Association for Cancer Research.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe or ongoing active UGIH. In selected patients, pre-endoscopic infusion of erythromycin significantly improves endoscopic visualization, reduces the need for second-look endoscopy, decreases the number of units of blood transfused, and reduces duration of hospital stay (strong recommendation, high quality evidence). MR7. Following hemodynamic resuscitation, ESGE recommends early (≤ 24 hours) upper GI endoscopy. Very early (< 12 hours) upper GI endoscopy may be considered in patients with high risk clinical features, namely: hemodynamic instability (tachycardia, hypotension) that persists despite ongoing attempts at volume resuscitation; in-hospital bloody emesis/nasogastric aspirate; or contraindication to the interruption of anticoagulation (strong recommendation, moderate quality evidence). MR8. ESGE recommends that peptic ulcers with spurting or oozing bleeding (Forrest classification Ia and Ib, respectively) or with a nonbleeding visible vessel (Forrest classification IIa) receive endoscopic hemostasis because these lesions are at high risk for persistent bleeding or rebleeding (strong recommendation, high quality evidence). MR9. ESGE recommends that peptic ulcers with an adherent clot (Forrest classification IIb) be considered for endoscopic clot removal. Once the clot is removed, any identified underlying active bleeding (Forrest classification Ia or Ib) or nonbleeding visible vessel (Forrest classification IIa) should receive endoscopic hemostasis (weak recommendation, moderate quality evidence). MR10. In patients with peptic ulcers having a flat pigmented spot (Forrest classification IIc) or clean base (Forrest classification III), ESGE does not recommend endoscopic hemostasis as these stigmata present a low risk of recurrent bleeding. In selected clinical settings, these patients may be discharged to home on standard PPI therapy, e. g., oral PPI once-daily (strong recommendation, moderate quality evidence). MR11. ESGE recommends that epinephrine injection therapy not be used as endoscopic monotherapy. If used, it should be combined with a second endoscopic hemostasis modality (strong recommendation, high quality evidence). MR12. ESGE recommends PPI therapy for patients who receive endoscopic hemostasis and for patients with adherent clot not receiving endoscopic hemostasis. PPI therapy should be high dose and administered as an intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour) for 72 hours post endoscopy (strong recommendation, high quality evidence). MR13. ESGE does not recommend routine second-look endoscopy as part of the management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). However, in patients with clinical evidence of rebleeding following successful initial endoscopic hemostasis, ESGE recommends repeat upper endoscopy with hemostasis if indicated. In the case of failure of this second attempt at hemostasis, transcatheter angiographic embolization (TAE) or surgery should be considered (strong recommendation, high quality evidence). MR14. In patients with NVUGIH secondary to peptic ulcer, ESGE recommends investigating for the presence of Helicobacter pylori in the acute setting with initiation of appropriate antibiotic therapy when H. pylori is detected. Re-testing for H. pylori should be performed in those patients with a negative test in the acute setting. Documentation of successful H. pylori eradication is recommended (strong recommendation, high quality evidence). MR15. In patients receiving low dose aspirin for secondary cardiovascular prophylaxis who develop peptic ulcer bleeding, ESGE recommends aspirin be resumed immediately following index endoscopy if the risk of rebleeding is low (e. g., FIIc, FIII). In patients with high risk peptic ulcer (FIa, FIb, FIIa, FIIb), early reintroduction of aspirin by day 3 after index endoscopy is recommended, provided that adequate hemostasis has been established (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

This dissertation provides information concerning the educational experience of females studying in undergraduate fields of math, engineering and science at a large research institution in the West. The majority of the participants were Project Access students, chosen because of their high achievements in science and mathematics during their secondary education. The study identifies and attempts to understand critical factors within the academic environment of science that contribute to female persistence in math, engineering and science (MES) disciplines. The study postulates that universities can make a difference in the education of women by providing programs that assure quality education and the fostering of female interest in science domains. The study recommends the incorporation of collaborative learning processes and teaching methods, cohort involvement and the fostering of study groups, encouragement of professorial associations with students, and internship and lab programs in an attempt to provide a more holistic and less fragmented education, thus benefiting women seeking MES degrees. Also, the research presented in this paper determined that the formation of positive associations and support networks was crucial to college female population studied. The interpretive study's aim is to enhance persistence rates among undergraduate students studying in math, engineering and science fields.

The quality of decision-making in multidisciplinary team meetings (MDTMs) depends on the quality of information presented and the quality of team processes. Few studies have examined these factors using a standardized approach. The aim of this study was to objectively document the processes involved in decision-making in MDTMs, document the outcomes in terms of whether a treatment recommendation was given (none vs. singular vs. multiple), and to identify factors related to type of treatment recommendation. An adaptation of the observer rating scale Multidisciplinary Tumor Board Metric for the Observation of Decision-Making (MDT-MODe) was used to assess the quality of the presented information and team processes in MDTMs. Data was analyzed using descriptive statistics and mixed logistic regression analysis. N = 249 cases were observed in N = 29 MDTMs. While cancer-specific medical information was judged to be of high quality, psychosocial information and information regarding patient views were considered to be of low quality. In 25% of the cases no, in 64% one, and in 10% more than one treatment recommendations were given (1% missing data). Giving no treatment recommendation was associated with duration of case discussion, duration of the MDTM session, quality of case history, quality of radiological information, and specialization of the MDTM. Higher levels of medical and treatment uncertainty during discussions were found to be associated with a higher probability for more than one treatment recommendation. The quality of different aspects of information was observed to differ greatly. In general, we did not find MDTMs to be in line with the principles of patient-centered care. Recommendation outcome varied substantially between different specializations of MDTMs. The quality of certain information was associated with the recommendation outcome. Uncertainty during discussions was related to more than one recommendation being considered. Time constraints were found to play an important role. Some of those aspects seem modifiable, which offers possibilities for the reorganization of MDTMs.

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston and piston ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and wear. An iterative process of simulation, experimentation and analysis is being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston and piston-ring dynamic and friction models have been developed and applied that illustrate the fundamental relationships between design parameters and friction losses. Low friction ring designs have already been recommended in a previous phase, withmore » full-scale engine validation partially completed. Current accomplishments include the addition of several additional power cylinder design areas to the overall system analysis. These include analyses of lubricant and cylinder surface finish and a parametric study of piston design. The Waukesha engine was found to be already well optimized in the areas of lubricant, surface skewness and honing cross-hatch angle, where friction reductions of 12% for lubricant, and 5% for surface characteristics, are projected. For the piston, a friction reduction of up to 50% may be possible by controlling waviness alone, while additional friction reductions are expected when other parameters are optimized. A total power cylinder friction reduction of 30-50% is expected, translating to an engine efficiency increase of two percentage points from its current baseline towards the goal of 50% efficiency. Key elements of the continuing work include further analysis and optimization of the engine piston design, in-engine testing of recommended lubricant and surface designs, design iteration and optimization of previously recommended technologies, and full-engine testing of a complete, optimized, low-friction power cylinder system.« less

Conventional system architectures, development processes, and tool environments often produce systems which exceed cost expectations and are obsolete before they are fielded. This paper explores some of the reasons for this and provides recommendations for how we can do better. These recommendations are based on DoD and NASA system developments and on our exploration and development of system/software engineering tools.

Data are currently being collected from hospital radiology information systems in the North West of the UK for the purposes of both clinical audit and patient dose audit. Could these data also be used to satisfy quality assurance (QA) requirements according to UK guidance? From 2008 to 2009, 731 653 records were submitted from 8 hospitals from the North West England. For automatic exposure control QA, the protocol from Institute of Physics and Engineering in Medicine (IPEM) report 91 recommends that milliamperes per second can be monitored for repeatability and reproducibility using a suitable phantom, at 70-81 kV. Abdomen AP and chest PA examinations were analysed to find the most common kilovoltage used with these records then used to plot average monthly milliamperes per second with time. IPEM report 91 also recommends that a range of commonly used clinical settings is used to check output reproducibility and repeatability. For each tube, the dose area product values were plotted over time for two most common exposure factor sets. Results show that it is possible to do performance checks of AEC systems; however more work is required to be able to monitor tube output performance. Procedurally, the management system requires work and the benefits to the workflow would need to be demonstrated.

To organize the clinical practice guidelines (CPGs) related to acupuncture included in the National Guideline Clearinghouse (NGC) to systematically summarize the diseases and disorders most commonly treated with acupuncture, the strength of recommendations for acupuncture and the quality of evidence. The NGC database was systematically searched for guidelines that included acupuncture as an intervention. Two independent reviewers studied the summaries and the full texts of the guidelines and included guidelines based on the inclusion and exclusion criteria. Thirty-nine guidelines were collected with 80 recommendations. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used to assess the quality of these guidelines. Of the 80 recommendations on acupuncture, 49 recommendations were clearly for acupuncture, 25 recommendations were against acupuncture and 6 recommendations did not indicate any clear recommendations, 37 recommendations were for painful diseases/disorders, and 12 recommendations were for non-painful diseases/disorders. Locomotor system disorders were the most common in the painful diseases/disorders category. Out of all the recommendations for acupuncture, most recommendations (87.76%) were weak in strength, and most of the evidence (40.84%) was of low quality. In the National Guideline Clearinghouse, the recommendations for acupuncture focus on painful diseases/disorders. The recommendations in the guidelines are not high in strength, and most of the evidence is moderate or low in quality.

The spectrum of vertical takeoff and landing (VTOL) type aircraft is examined to determine which aircraft are most likely to achieve high subsonic cruise speeds and have hover qualities similar to a helicopter. Two civil mission profiles are considered: a 600-n.mi. mission for a 15- and a 30-passenger payload. Applying current technology, only the 15- and 30-passenger tiltfold aircraft are capable of attaining the 450-knot design goal. The two tiltfold aircraft at 450 knots and a 30-passenger tiltrotor at 375 knots were further developed for the Task II technology analysis. A program called High-Speed Total Envelope Proprotor (HI-STEP) is recommended to meet several of these issues based on the tiltrotor concept. A program called Tiltfold System (TFS) is recommended based on the tiltrotor concept. A task is identified to resolve the best design speed from productivity and demand considerations based on the technology that emerges from the recommended programs. HI-STEP's goals are to investigate propulsive efficiency, maneuver loads, and aeroelastic stability. Programs currently in progress that may meet the other technology needs include the Integrated High Performance Turbine Engine Technology (IHPTET) (NASA Lewis) and the Advanced Structural Concepts Program funded through NASA Langley.

The basic objective of this research effort was to perform a comparative analysis of the Quality Assurance practices related to the structural concrete phase on nine nuclear power plant projects which are (or have been) under construction in the United States in the past ten years. This analysis identified the response of each Quality Assurance program to the applicable criteria of 10 CFR Part 50, Appendix B as well as to the pertinent regulatory requirements and industry standards. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspectsmore » were examined whenever they interfaced with the construction aspects. For those aspects of the Quality Assurance system which can be considered managerial in nature (i.e., organizational relationships, types of Quality Assurance programs, corrective action procedures, etc.) an attempt has been made to present the alternative approaches that were identified. For those aspects of the Quality Assurance system which are technical in nature (i.e., the frequency of testing for slump, compressive strength, etc.) an attempt has been made to present a comparative analysis between projects and in relation to the recommended or mandated practices presented in the appropriate industry codes and standards.« less

Background People often search for information on influenza A(H1N1)v prevention on the web. The extent to which information found on the Internet is consistent with recommendations issued by the World Health Organization is unknown. Methods We conducted a search for "swine flu" accessing 3 of the most popular search engines through different proxy servers located in 4 English-speaking countries (Australia, Canada, UK, USA). We explored each site resulting from the searches, up to 4 clicks starting from the search engine page, analyzing availability of World Health Organization recommendations for swine flu prevention. Results Information on hand cleaning was reported on 79% of the 147 websites analyzed; staying home when sick was reported on 77.5% of the websites; disposing tissues after sneezing on 75.5% of the websites. Availability of other recommendations was lower. The probability of finding preventative recommendations consistent with World Health Organization varied by country, type of website, and search engine. Conclusions Despite media coverage on H1N1 influenza, relevant information for prevention is not easily found on the web.

This European guideline for the diagnosis and treatment of insomnia was developed by a task force of the European Sleep Research Society, with the aim of providing clinical recommendations for the management of adult patients with insomnia. The guideline is based on a systematic review of relevant meta-analyses published till June 2016. The target audience for this guideline includes all clinicians involved in the management of insomnia, and the target patient population includes adults with chronic insomnia disorder. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was used to grade the evidence and guide recommendations. The diagnostic procedure for insomnia, and its co-morbidities, should include a clinical interview consisting of a sleep history (sleep habits, sleep environment, work schedules, circadian factors), the use of sleep questionnaires and sleep diaries, questions about somatic and mental health, a physical examination and additional measures if indicated (i.e. blood tests, electrocardiogram, electroencephalogram; strong recommendation, moderate- to high-quality evidence). Polysomnography can be used to evaluate other sleep disorders if suspected (i.e. periodic limb movement disorder, sleep-related breathing disorders), in treatment-resistant insomnia, for professional at-risk populations and when substantial sleep state misperception is suspected (strong recommendation, high-quality evidence). Cognitive behavioural therapy for insomnia is recommended as the first-line treatment for chronic insomnia in adults of any age (strong recommendation, high-quality evidence). A pharmacological intervention can be offered if cognitive behavioural therapy for insomnia is not sufficiently effective or not available. Benzodiazepines, benzodiazepine receptor agonists and some antidepressants are effective in the short-term treatment of insomnia (≤4 weeks; weak recommendation, moderate-quality evidence). Antihistamines, antipsychotics, melatonin and phytotherapeutics are not recommended for insomnia treatment (strong to weak recommendations, low- to very-low-quality evidence). Light therapy and exercise need to be further evaluated to judge their usefulness in the treatment of insomnia (weak recommendation, low-quality evidence). Complementary and alternative treatments (e.g. homeopathy, acupuncture) are not recommended for insomnia treatment (weak recommendation, very-low-quality evidence). © 2017 European Sleep Research Society.

Given the increasing complexity of technology in our society, the United States has a growing demand for a more highly educated technical workforce. Unfortunately, the proportion of United States citizens earning a PhD in engineering has been declining and there is concern about meeting the economic, national security and quality of life needs of our country. This mixed methods sequential exploratory instrument design study identified factors that facilitate or inhibit interest in engineering PhD programs among domestic engineering undergraduate students in the United States. This study developed a testable theory for how domestic students become interested in engineering PhD programs and a measure of that process, the Exploring Engineering Interest Inventory (EEII). The study was conducted in four phases. The first phase of the study was a qualitative grounded theory exploration of interest in the engineering PhD. Qualitative data were collected from domestic engineering students, engineering faculty and industry professional who had earned a PhD in engineering. The second phase, instrument development, developed the Exploring Engineering Interest Inventory (EEII), a measurement instrument designed with good psychometric properties to test a series of preliminary hypotheses related to the theory generated in the qualitative phase. In the third phase of the study, the EEII was used to collect data from a larger sample of junior and senior engineering majors. The fourth phase integrated the findings from the qualitative and quantitative phases. Four factors were identified as being significant influences of interest in the engineering PhD: Personal characteristics, educational environment, misperceptions of the economic and personal costs, and misperceptions of engineering work. Recommendations include increasing faculty encouragement of students to pursue an engineering PhD and programming to correct the misperceptions of the costs of the engineering PhD and the nature of the work that PhD engineers do. The tested model provides engineering educators with information to help them prioritize their efforts to increase interest in the engineering PhD among domestic students.
The reliability-quality relationship for quality systems and quality risk management.
Claycamp, H Gregg; Rahaman, Faiad; Urban, Jason M
2012-01-01
Engineering reliability typically refers to the probability that a system, or any of its components, will perform a required function for a stated period of time and under specified operating conditions. As such, reliability is inextricably linked with time-dependent quality concepts, such as maintaining a state of control and predicting the chances of losses from failures for quality risk management. Two popular current good manufacturing practice (cGMP) and quality risk management tools, failure mode and effects analysis (FMEA) and root cause analysis (RCA) are examples of engineering reliability evaluations that link reliability with quality and risk. Current concepts in pharmaceutical quality and quality management systems call for more predictive systems for maintaining quality; yet, the current pharmaceutical manufacturing literature and guidelines are curiously silent on engineering quality. This commentary discusses the meaning of engineering reliability while linking the concept to quality systems and quality risk management. The essay also discusses the difference between engineering reliability and statistical (assay) reliability. The assurance of quality in a pharmaceutical product is no longer measured only "after the fact" of manufacturing. Rather, concepts of quality systems and quality risk management call for designing quality assurance into all stages of the pharmaceutical product life cycle. Interestingly, most assays for quality are essentially static and inform product quality over the life cycle only by being repeated over time. Engineering process reliability is the fundamental concept that is meant to anticipate quality failures over the life cycle of the product. Reliability is a well-developed theory and practice for other types of manufactured products and manufacturing processes. Thus, it is well known to be an appropriate index of manufactured product quality. This essay discusses the meaning of reliability and its linkages with quality systems and quality risk management.
Summary of the effects of engine throttle response on airplane formation-flying qualities
NASA Technical Reports Server (NTRS)
Walsh, Kevin R.
1993-01-01
A flight evaluation was conducted to determine the effect of engine throttle response characteristics on precision formation-flying qualities. A variable electronic throttle control system was developed and flight-tested on a TF-104G airplane with a J79-11B engine at the NASA Dryden Flight Research Facility. This airplane was chosen because of its known, very favorable thrust response characteristics. Ten research flights were flown to evaluate the effects of throttle gain, time delay, and fuel control rate limiting on engine handling qualities during a demanding precision wing formation task. Handling quality effects of lag filters and lead compensation time delays were also evaluated. The Cooper and Harper Pilot Rating Scale was used to assign levels of handling quality. Data from pilot ratings and comments indicate that throttle control system time delays and rate limits cause significant degradations in handling qualities. Threshold values for satisfactory (level 1) and adequate (level 2) handling qualities of these key variables are presented. These results may provide engine manufacturers with guidelines to assure satisfactory handling qualities in future engine designs.

This study evaluated the readability, accessibility, usability, and reliability of vascular surgery information on the Internet in the English language. The Google, Yahoo, and MSN/Bing search engines were searched for "carotid endarterectomy," "EVAR or endovascular aneurysm repair," and "varicose veins or varicose veins surgery." The first 50 Web sites from each search engine for each topic were analyzed. The Flesch Reading Ease Score and Gunning Fog Index were calculated to assess readability. The LIDA tool (Minervation Ltd, Oxford, UK) was used to assess accessibility, usability, and reliability. The Web sites were difficult to read and comprehend. The mean Flesch Reading Ease scores were 53.53 for carotid endarterectomy, 50.53 for endovascular aneurysm repair, and 58.59 for varicose veins. The mean Gunning Fog Index scores were 12.3 for carotid endarterectomy, 12.12 for endovascular aneurysm repair, and 10.69 for varicose veins. The LIDA values for accessibility were good, but the results for usability and reliability were poor. Internet information on vascular surgical conditions and procedures is poorly written and unreliable. We suggest that health professionals should recommend Web sites that are easy to read and contain high-quality surgical information. Medical information on the Internet must be readable, accessible, usable, and reliable. Copyright © 2012 Society for Vascular Surgery. Published by Mosby, Inc. All rights reserved.
Directions for combustion engine aerosol measurement in the 21st century.
Maricq, M Matti; Maldonado, Hector
2010-10-01
The Coordinating Research Council convened two Real-Time PM Measurement Workshops in December 2008 and March 2009 to take an intensive look at the current status and future directions of combustion aerosol measurement. The purpose was to examine the implications of parallel rapid developments over the past decade in ambient aerosol science, engine aftertreatment technology, and aerosol measurement methodology, which provide benefits and challenges to the stakeholders in air quality management. The workshops were organized into sessions targeting key issues in ambient and source combustion particulate matter (PM). These include (1) metrics to characterize and quantify PM, (2) the need to reconcile ambient and source measurements, (3) the role of atmospheric transformations on modeling emissions and exposures, (4) the impact of sampling conditions on PM measurement, and (5) the potential benefits of novel PM instrumentation. This paper distills the material presented by subject experts and the insights derived from the in-depth discussions that formed the core of each session. The paper's objectives are to identify areas of consensus that allow wider practical application of the past decade's advances in combustion aerosol measurement to improve emissions and air quality modeling, develop emissions reduction strategies, and to recommend directions for progress on issues in which uncertainties remain.

Feedback from engineers and scientists in the academic and industrial community provided an assessment of the usage and perceived quality of NASA Langley generated STI and the familiarity and usage of selected NASA publications and services and identified ways to increase the accessibility of Langley STI. The questionnaire utilized both open and closed ended questions and was pretested for finalization. The questions were organized around the seven objectives for Phase IV. From a contact list of nearly 1,200 active industrial and academic researchers, approximately 600 addresses were verified. The 497 persons who agreed to participate were mailed questionnaires. The 381 completed questionnaires received by the cutoff date were analyzed. Based on the survey findings, recommendations were made for increasing the familiarity with and use of NASA and Langley STI and selected NASA publications and services. In addition, recommendations were made for increasing the accessibility of Langley STI.
Modifications to the 4x7 meter tunnel for acoustic research: Engineering feasibility study
NASA Technical Reports Server (NTRS)
1986-01-01
The NASA-Langley Research Center 4 x 7 Meter Low Speed Wind Tunnel is currently being used for low speed aerodynamics, V/STOL aerodynamics and, to a limited extent, rotorcraft noise research. The deficiencies of this wind tunnel for both aerodynamics and aeroacoustics research have been recognized for some time. Modifications to the wind tunnel are being made to improve the test section flow quality and to update the model cart systems. A further modification of the 4 x 7 Meter Wind Tunnel to permit rotorcraft model acoustics research has been proposed. As a precursor to the design of the proposed modifications, NASA is conducted both in-house and contracted studies to define the acoustic environment within the wind tunnel and to provide recommendations or the reduction of the wind tunnel background noise to a level acceptable to acoustics researchers. One of these studies by an acoustics consultant, has produced the primary reference documents that define the wind tunnel noise sources and outline recommended solutions.

Professional societies, like many other organizations around the world, have recognized the need to use more rigorous processes to ensure that healthcare recommendations are informed by the best available research evidence. This is the 11th of a series of 14 articles that methodologists and researchers from around the world prepared to advise guideline developers for respiratory and other diseases on how to achieve this goal. For this article, we developed five key questions and updated a review of the literature on moving from evidence to recommendations. We addressed the following specific questions.What is the strength of a recommendation and what determines the strength? What are the implications of strong and weak recommendations for patients, clinicians, and policy makers? Should guideline panels make recommendations in the face of very low-quality evidence? Under which circumstances should guideline panels make research recommendations? How should recommendations be formulated and presented? We searched PubMed and other databases of methodological studies for existing systematic reviews and relevant methodological research. We did not conduct systematic reviews ourselves. Our conclusions are based on available evidence, consideration of what guideline developers are doing, and pre- and postworkshop discussions. The strength of a recommendation reflects the extent to which guideline developers can, across the range of patients for whom the recommendations are intended, be confident that the desirable effects of following the recommendation outweigh the undesirable effects. Four factors influence the strength of a recommendation: the quality of evidence supporting the recommendation, the balance between desirable and undesirable effects, the uncertainty or variability of patient values and preferences, and costs. Strong and weak (also called "conditional") recommendations have distinct implications for patients, clinicians, and policy makers. Adherence to strong recommendations or, in the case of weak (conditional) recommendations, documentation of discussion or shared decision making with a patient, might be used as quality measures or performance indicators. Clinicians desire guidance regardless of the quality of the underlying evidence. Very low-quality evidence should ideally result in either appropriately labeled recommendations (i.e., as based on very low-quality evidence) or a statement that the guideline panel did not reach consensus on the recommendation due to the lack of confidence in the effect estimates. However, guideline panels often have more resources, time, and information than practicing clinicians. Therefore, they may be in a position to use their best judgments to make recommendations even when there is very low-quality evidence, although some guideline developers disagree with this approach and prefer a general approach of not making recommendations in the face of very low-quality evidence. Guideline panels should consider making research recommendations when there is important uncertainty about the desirable and undesirable effects of an intervention, further research could reduce that uncertainty, and the potential benefits and savings of reducing the uncertainty outweigh the potential harms of not making the research recommendation. Recommendations for additional research should be as precise and specific as possible.

To advance the quality of mental healthcare in Europe by developing guidance on implementing quality assurance. We performed a systematic literature search on quality assurance in mental healthcare and the 522 retrieved documents were evaluated by two independent reviewers (B.J. and J.Z.). Based on these evaluations, evidence tables were generated. As it was found that these did not cover all areas of mental healthcare, supplementary hand searches were performed for selected additional areas. Based on these findings, fifteen graded recommendations were developed and consented by the authors. Review by the EPA Guidance Committee and EPA Board led to two additional recommendations (on immigrant mental healthcare and parity of mental and physical healthcare funding). Although quality assurance (measures to keep a certain degree of quality), quality control and monitoring (applying quality indicators to the current degree of quality), and quality management (coordinated measures and activities with regard to quality) are conceptually distinct, in practice they are frequently used as if identical and hardly separable. There is a dearth of controlled trials addressing ways to optimize quality assurance in mental healthcare. Altogether, seventeen recommendations were developed addressing a range of aspects of quality assurance in mental healthcare, which appear usable across Europe. These were divided into recommendations about structures, processes and outcomes. Each recommendation was assigned to a hierarchical level of analysis (macro-, meso- and micro-level). There was a lack of evidence retrievable by a systematic literature search about quality assurance of mental healthcare. Therefore, only after further topics and search had been added it was possible to develop recommendations with mostly medium evidence levels. Evidence-based graded recommendations for quality assurance in mental healthcare were developed which should next be implemented and evaluated for feasibility and validity in some European countries. Due to the small evidence base identified corresponding to the practical obscurity of the concept and methods, a European research initiative is called for by the stakeholders represented in this Guidance to improve the educational, methodological and empirical basis for a future broad implementation of measures for quality assurance in European mental healthcare.

To increase understanding of how to raise the quality of rheumatology guidelines by reviewing European League Against Rheumatism (EULAR) management recommendations, using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, 10 years after publication of the EULAR standardized operating procedures (SOP) for the production of recommendations. It was hoped that this work could help inform improvements in guideline development by other societies and organizations. The SOP were published in 2004 to ensure the quality of EULAR-endorsed recommendations. We reviewed 27 published EULAR recommendations for management using the AGREE II tool. This provides a framework to assess the quality of guidelines across six broad domains using 23 specific questions. Overall the EULAR recommendations reviewed have been performed to a high standard. There are particular strengths in the methodology and presentation of the guidelines; however, the results indicate areas for development in future recommendations: in particular, stakeholder involvement and applicability of the recommendations. Improvements in quality were evident in recent years, with patient representation in 9 of 15 (60.0%) recommendations published 2010-14 compared with 4 of 12 (33.3%) published 2000-09. In the last 10 years the overall quality of recommendations was good, with standards improving over the decade following publication of the SOP. However, this review process has identified potential areas for improvement, especially in patient representation and provision of implementation tools. The lessons from this work can be applied to the development of rheumatology guidelines by other societies and organizations. © The Author 2015.

The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations on the management of gout. Using the ACP grading system, the committee based these recommendations on a systematic review of randomized, controlled trials; systematic reviews; and large observational studies published between January 2010 and March 2016. Clinical outcomes evaluated included pain, joint swelling and tenderness, activities of daily living, patient global assessment, recurrence, intermediate outcomes of serum urate levels, and harms. The target audience for this guideline includes all clinicians, and the target patient population includes adults with acute or recurrent gout. ACP recommends that clinicians choose corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), or colchicine to treat patients with acute gout. (Grade: strong recommendation, high-quality evidence). ACP recommends that clinicians use low-dose colchicine when using colchicine to treat acute gout. (Grade: strong recommendation, moderate-quality evidence). ACP recommends against initiating long-term urate-lowering therapy in most patients after a first gout attack or in patients with infrequent attacks. (Grade: strong recommendation, moderate-quality evidence). ACP recommends that clinicians discuss benefits, harms, costs, and individual preferences with patients before initiating urate-lowering therapy, including concomitant prophylaxis, in patients with recurrent gout attacks. (Grade: strong recommendation, moderate-quality evidence).

An assessment of NASA's safety performance for 1983 affirms that NASA Headquarters and Center management teams continue to hold the safety of manned flight to be their prime concern, and that essential effort and resources are allocated for maintaining safety in all of the development and operational programs. Those conclusions most worthy of NASA management concentration are given along with recommendations for action concerning; product quality and utility; space shuttle main engine; landing gear; logistics and management; orbiter structural loads, landing speed, and pitch control; the shuttle processing contractor; and the safety of flight operations. It appears that much needs to be done before the Space Transportation System can achieve the reliability necessary for safe, high rate, low cost operations.

The kinds and quality of blockages to creativity are studied for two groups of employees, a group of peer-identified creative individuals and a group attending a career/life planning workshop. The employees from both groups represent a cross section of scientists/engineers, administrators, and technical support personnel and administrative support personnel. The design and results of the study are discussed, and some recommendations are made. It was found that the blockages of creative employees, as a group, were different from those of the self-selected, workshop group. Blockages reported by the peer-identified group were lack of time, office disharmony, and personal limitations, whilemore » those reported by the self-selected group were lack of time and fear of risk.

To describe types of recommendations represented in a curated online evidence library, report on the quality of evidence-based recommendations pertaining to diagnostic imaging exams, and assess underlying knowledge representation. The evidence library is populated with clinical decision rules, professional society guidelines, and locally developed best practice guidelines. Individual recommendations were graded based on a standard methodology and compared using chi-square test. Strength of evidence ranged from grade 1 (systematic review) through grade 5 (recommendations based on expert opinion). Finally, variations in the underlying representation of these recommendations were identified. The library contains 546 individual imaging-related recommendations. Only 15% (16/106) of recommendations from clinical decision rules were grade 5 vs 83% (526/636) from professional society practice guidelines and local best practice guidelines that cited grade 5 studies (P < .0001). Minor head trauma, pulmonary embolism, and appendicitis were topic areas supported by the highest quality of evidence. Three main variations in underlying representations of recommendations were "single-decision," "branching," and "score-based." Most recommendations were grade 5, largely because studies to test and validate many recommendations were absent. Recommendation types vary in amount and complexity and, accordingly, the structure and syntax of statements they generate. However, they can be represented in single-decision, branching, and score-based representations. In a curated evidence library with graded imaging-based recommendations, evidence quality varied widely, with decision rules providing the highest-quality recommendations. The library may be helpful in highlighting evidence gaps, comparing recommendations from varied sources on similar clinical topics, and prioritizing imaging recommendations to inform clinical decision support implementation.
Glue ear: how good is the information on the World Wide Web?
Ritchie, L; Tornari, C; Patel, P M; Lakhani, R
2016-02-01
This paper objectively evaluates current information available to the general public related to glue ear on the World Wide Web. The term 'glue ear' was typed into the 3 most frequently used internet search engines - Google, Bing and Yahoo - and the first 20 links were analysed. The first 400 words of each page were used to calculate the Flesch-Kincaid readability score. Each website was subsequently graded using the Discern instrument, which gauges quality and content of literature. The websites Webmd.boots.com, Bupa.co.uk and Patient.co.uk received the highest overall scores. These reflected top scores in either readability or Discern instrument assessment, but not both. Readability and Discern scores increased with the presence of a marketing or advertising incentive. The Patient.co.uk website had the highest Discern score and third highest readability score. There is huge variation in the quality of information available to patients on the internet. Some websites may be accessible to a wide range of reading ages but have poor quality content, and vice versa. Clinicians should be aware of indicators of quality, and use validated instruments to assess and recommend literature.

Summary of OEM Idling Recommendations from Vehicle Owner's Manuals
DOE Office of Scientific and Technical Information (OSTI.GOV)
Keel-Blackmon, Kristy; Curran, Scott; Lapsa, Melissa Voss
The project upon which this report is based was conceived in 2012 during discussions between the East Tennessee Clean Fuels Coalition (ETCleanFuels) and Oak Ridge National Laboratory (ORNL) who both noted that a detailed summary of idling recommendations for a wide variety of engines and vehicles were not available in the literature. The two organizations agreed that ETCleanFuels would develop a first-of-its-kind collection of idling recommendations from the owner’s manuals of modern production vehicles. Vehicle engine idling, a subject that has long been debated, is largely shrouded in misinformation. The justifications for idling seem to be many: driver comfort, waitingmore » in lines, and talking on cell phones to name a few. Assuredly, a great number of people idle because of the myths and misinformation surrounding this issue. This report addresses these myths by turning to statements taken directly from the automobile and engine manufacturers themselves.« less

We systematically identified and reviewed the methods and consistency of recommendations of recently developed clinical practice guidelines (CPG) and best practice statements (BPS) on the evaluation of the infertile male. MEDLINE and related engines as well as guidelines' Web sites were searched for CPG and BPS written in English on the general evaluation of male infertility published between January 2008 and April 2015. Four guidelines were identified, all of which reported to have been recently updated. Systematic review was not consistently used in the BPS despite being reported in the CPG. Only one of them reported having a patient representative in its development team. The CPG issued by the European Association of Urology (EAU) graded some recommendations and related that to levels (but not quality) of evidence. Overall, the BPS issued respectively by the American Urological Association and American Society for Reproductive Medicine concurred with each other, but both differed from the EAU guidelines with regard to methods of collection, extraction and interpretation of data. None of the guidelines incorporated health economics. Important specific limitations of conventional semen analysis results were ignored by all guidelines. Besides variation in the methodological quality, implementation strategies were not reported in two out of four guidelines. While the various panels of experts who contributed to the development of the CPG and BPS reviewed should be commended on their tremendous efforts aiming to establish a clinical standard in both the evaluation and management of male infertility, we recognized inconsistencies in the methodology of their synthesis and in the contents of their final recommendations. These discrepancies pose a barrier in the general implementation of these guidelines and may limit their utility in standardizing clinical practice or improving health-related outcomes. Continuous efforts are needed to generate high-quality evidence to allow further development of these important guidelines for the evaluation and management of males suffering from infertility.
The creation, management, and use of data quality information for life cycle assessment.
Edelen, Ashley; Ingwersen, Wesley W
2018-04-01
Despite growing access to data, questions of "best fit" data and the appropriate use of results in supporting decision making still plague the life cycle assessment (LCA) community. This discussion paper addresses revisions to assessing data quality captured in a new US Environmental Protection Agency guidance document as well as additional recommendations on data quality creation, management, and use in LCA databases and studies. Existing data quality systems and approaches in LCA were reviewed and tested. The evaluations resulted in a revision to a commonly used pedigree matrix, for which flow and process level data quality indicators are described, more clarity for scoring criteria, and further guidance on interpretation are given. Increased training for practitioners on data quality application and its limits are recommended. A multi-faceted approach to data quality assessment utilizing the pedigree method alongside uncertainty analysis in result interpretation is recommended. A method of data quality score aggregation is proposed and recommendations for usage of data quality scores in existing data are made to enable improved use of data quality scores in LCA results interpretation. Roles for data generators, data repositories, and data users are described in LCA data quality management. Guidance is provided on using data with data quality scores from other systems alongside data with scores from the new system. The new pedigree matrix and recommended data quality aggregation procedure can now be implemented in openLCA software. Additional ways in which data quality assessment might be improved and expanded are described. Interoperability efforts in LCA data should focus on descriptors to enable user scoring of data quality rather than translation of existing scores. Developing and using data quality indicators for additional dimensions of LCA data, and automation of data quality scoring through metadata extraction and comparison to goal and scope are needed.
[Infant food diversification: Is the information available on the Internet valid?].
Banti, T; Carsin, A; Chabrol, B; Fabre, A
2016-07-01
The Internet provides easy access to information on health, but the quality and validity of this information are variable. To evaluate the quality of websites and the information provided on the timing and consequences of food diversification for infants. We analyzed the websites addressing infant food diversification that appeared on the first two pages of the search engines Google, Yahoo, and Bing. The websites were selected from four different queries. We initially assessed (a) the structure of the websites with two instruments (the Criteria for Assessing the Quality of Health Information on the Internet (HITI) and NetScoring) and (b) the presence of certification (quality label Health on the Net [HON] Code). Secondly, we evaluated the content of the websites concerning the time of introducing five classes of foods (gluten, fat, allergenic foods, solid foods, and animal protein), the duration of breastfeeding, and four potential consequences of food diversification (allergy, nutritional, autoimmune, and cardiovascular). Our repository was based on the most recent recommendations of the French Society of Pediatrics published in 2008. In all, 19 websites were included. Six of 19 websites scored above average on the two instruments (average: 131.26/312 with NetScoring and 46.73/104 with HITI). No correlation was observed between the referencing of websites analyzed and the notes obtained with both instruments. A majority of the websites analyzed were consistent with the recommendation favoring breast milk (100%), the age of introducing meat proteins (74%), and the age of introducing gluten (63%). A majority of the websites disagreed on the age of introducing solid foods (16%). As four consequences, only the risk of allergy (63%) was cited by a majority of the sites. There was a small nonsignificant correlation between the results obtained for the website about introducing solid foods and the results obtained for the websites analyzed with the NetScoring and HITI instruments (Pearson coefficient 41%, p=0.07). The websites were in partial agreement with the French recommendations. To date, the pediatrician remains the main actor in guiding parents on food diversification.

The use of statistical techniques to build approximations of expensive computer analysis codes pervades much of todays engineering design. These statistical approximations, or metamodels, are used to replace the actual expensive computer analyses, facilitating multidisciplinary, multiobjective optimization and concept exploration. In this paper we review several of these techniques including design of experiments, response surface methodology, Taguchi methods, neural networks, inductive learning, and kriging. We survey their existing application in engineering design and then address the dangers of applying traditional statistical techniques to approximate deterministic computer analysis codes. We conclude with recommendations for the appropriate use of statistical approximation techniques in given situations and how common pitfalls can be avoided.

To assess the quality of guidelines published in peer-reviewed literature concerning the role of physiotherapy in the management of patients with RA. A systematic literature search for clinical practice guidelines that included physiotherapy interventions was performed in four electronic databases. We assessed the quality of the selected guidelines using the appraisal of guidelines for research and evaluation (AGREE) instrument. In addition, the recommendations of guidelines with the highest quality scores were summarized. Eight clinical practice guidelines fulfilled the inclusion criteria. Scope/purpose was the most often adequately addressed AGREE domain (in seven of the eight guidelines) and applicability the least (in two of the eight guidelines). Based on the AGREE domain scores, six guidelines could be recommended or strongly recommended for clinical use. Five out of these six (strongly) recommended guidelines included a recommendation on exercise therapy and/or patient education, with these interventions being recommended in every case. Transcutaneous electrical nerve stimulation and thermotherapy were recommended in four of these six guidelines. US, thermotherapy, low-level laser therapy, massage, passive mobilization and balneotherapy were addressed in one or two of these six guidelines. Six of eight clinical practice guidelines addressing physiotherapy interventions were recommended or strongly recommended according to the AGREE instrument. In general, guideline recommendations on physiotherapy intervention, from both the recommended guidelines as well as from the not recommended guidelines, lacked detail concerning mode of delivery, intensity, frequency and duration.

Fertility preservation care for children, adolescents, and young adults (CAYAs) with cancer is not uniform among practitioners. To ensure high-quality care, evidence-based clinical practice guidelines (CPGs) are essential. The authors identified existing CPGs for fertility preservation in CAYAs with cancer, evaluated their quality, and explored differences in recommendations. A systematic search in PubMed (January 2000-October 2014); guideline databases; and Web sites of oncology, pediatric, and fertility organizations was performed. Two reviewers evaluated the quality of the identified CPGs using the Appraisal of Guidelines for Research and Evaluation II Instrument (AGREE II). From high-quality CPGs, the authors evaluated concordant and discordant areas among the recommendations. A total of 25 CPGs regarding fertility preservation were identified. The average AGREE II domain scores (scale of 0%-100%) varied from 15% on applicability to 100% on clarity of presentation. The authors considered 8 CPGs (32%) to be of high quality, which was defined as scores ≥60% in any 4 domains. Large variations in the recommendations of the high-quality CPGs were observed, with 87.2% and 88.6%, respectively, of discordant guideline areas among the fertility preservation recommendations for female and male patients with cancer. Only approximately one-third of the identified CPGs were found to be of sufficient quality. Of these CPGs, the fertility preservation recommendations varied substantially, which can be a reflection of inadequate evidence for specific recommendations, thereby hindering the ability of providers to deliver high-quality care. CPGs including a transparent decision process for fertility preservation can help health care providers to deliver optimal and uniform care, thus improving the quality of life of CAYAs with cancer and cancer survivors.

To provide an overview of (1) the consistency of Type 2 Diabetes Clinical Practice Guidelines recommendations on the delivery of nutrition therapy and (2) Clinical Practice Guideline quality. Large international clinical practice guideline repositories, diabetes organisation websites, and electronic databases (Pubmed, Scopus), were searched to identify Clinical Practice Guidelines for adults with type 2 diabetes published 2005 to August 2014. Recommendations on the delivery of nutrition therapy were extracted and inductive content analysis was used to analyse consistency. Two researchers independently assessed guideline quality using the AGREE II tool. Nine topics were identified from the recommendations. Overall the consistency of the recommendations was related to guideline type. Compared with nutrition-specific guidelines, the broad ones had a broader focus and included more patient-focused recommendations. The ten Clinical Practice Guidelines assessed included six broad guidelines and four nutrition specific guidelines. Based on AGREE II analysis, the broad guidelines were higher quality than nutrition-specific ones. Broad Clinical Practice Guidelines were higher quality and included more patient-focused recommendations than nutrition-specific ones. Our findings suggest a need for nutrition-specific guidelines to be modified to include greater patient-focus, or for practitioners delivering nutrition therapy to adopt broad Clinical Practice Guidelines.

This guideline updates the 2008 American College of Physicians (ACP) recommendations on treatment of low bone density and osteoporosis to prevent fractures in men and women. This guideline is endorsed by the American Academy of Family Physicians. The ACP Clinical Guidelines Committee based these recommendations on a systematic review of randomized controlled trials; systematic reviews; large observational studies (for adverse events); and case reports (for rare events) that were published between 2 January 2005 and 3 June 2011. The review was updated to July 2016 by using a machine-learning method, and a limited update to October 2016 was done. Clinical outcomes evaluated were fractures and adverse events. This guideline focuses on the comparative benefits and risks of short- and long-term pharmacologic treatments for low bone density, including pharmaceutical prescriptions, calcium, vitamin D, and estrogen. Evidence was graded according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. The target audience for this guideline includes all clinicians. The target patient population includes men and women with low bone density and osteoporosis. ACP recommends that clinicians offer pharmacologic treatment with alendronate, risedronate, zoledronic acid, or denosumab to reduce the risk for hip and vertebral fractures in women who have known osteoporosis. (Grade: strong recommendation; high-quality evidence). ACP recommends that clinicians treat osteoporotic women with pharmacologic therapy for 5 years. (Grade: weak recommendation; low-quality evidence). ACP recommends that clinicians offer pharmacologic treatment with bisphosphonates to reduce the risk for vertebral fracture in men who have clinically recognized osteoporosis. (Grade: weak recommendation; low-quality evidence). ACP recommends against bone density monitoring during the 5-year pharmacologic treatment period for osteoporosis in women. (Grade: weak recommendation; low-quality evidence). ACP recommends against using menopausal estrogen therapy or menopausal estrogen plus progestogen therapy or raloxifene for the treatment of osteoporosis in women. (Grade: strong recommendation; moderate-quality evidence). ACP recommends that clinicians should make the decision whether to treat osteopenic women 65 years of age or older who are at a high risk for fracture based on a discussion of patient preferences, fracture risk profile, and benefits, harms, and costs of medications. (Grade: weak recommendation; low-quality evidence).
[Injuries in the Martial Arts Judo, Taekwondo and Wrestling - A Systematic Review].
Jäggi, U; Joray, C P; Brülhart, Y; Luijckx, E; Rogan, S
2015-12-01
Martial arts such as judo, taekwondo and wrestling are regulated, usually athletic duels. The aim is to score better than your opponent or to win. As with any type of sport, athletes in martial arts sustain minor and major injuries, which may have many negative consequences. In addition, sports injuries and their rehabilitation generate high costs to the healthcare system. In contrast to the FIFA 11+ warm-up program, no preventive programs have been postulated for injury prevention in these martial arts. Therefore, the aim of this systematic review was to summarise the latest research findings and to evaluate whether initial recommendations can be given for the reduction of injuries in the martial arts judo, wrestling and taekwondo. To gain an overview of the latest research findings, we searched for systematic reviews in PEDro, PubMed, Cochrane and the internet search engine Google Scholar. The methodological quality of these reviews was assessed using the Critical Appraisal Tool for a Systematic Review (CASP), and data was extracted on the risk of injury, injury location and injury type. It was found that all three review articles are of low to moderate methodological quality. Regarding injury location, it became evident that the extremities are particularly vulnerable to injury in all three martial arts. Effusion was observed to be the most common type of injury. Due to the moderate methodological quality and the injury type of effusion, it is not possible to formulate recommendations for injury prevention. Moreover, uniform definitions should be developed to describe sports injuries. © Georg Thieme Verlag KG Stuttgart · New York.

Los Alamos National Laboratory (LANL) uses external peer review to measure and continuously improve the quality of its science, technology and engineering (STE). LANL uses capability reviews to assess the STE quality and institutional integration and to advise Laboratory Management on the current and future health of the STE. Capability reviews address the STE integration that LANL uses to meet mission requirements. STE capabilities are define to cut across directorates providing a more holistic view of the STE quality, integration to achieve mission requirements, and mission relevance. The scope of these capabilities necessitate that there will be significant overlap inmore » technical areas covered by capability reviews (e.g ., materials research and weapons science and engineering). In addition, LANL staff may be reviewed in different capability reviews because of their varied assignments and expertise. LANL plans to perform a complete review of the Laboratory's STE capabilities (hence staff) in a three-year cycle. The principal product of an external review is a report that includes the review committee's assessments, commendations, and recommendations for STE. The Capability Review Committees serve a dual role of providing assessment of the Laboratory's technical contributions and integration towards its missions and providing advice to Laboratory Management. The assessments and advice are documented in reports prepared by the Capability Review Committees that are delivered to the Director and to the Principal Associate Director for Science, Technology and Engineering (PADSTE). This report will be used by Laboratory Management for STE assessment and planning. The report is also provided to the Department of Energy (DOE) as part of LANL's Annual Performance Plan and to the Los Alamos National Security (LANS) LLC's Science and Technology Committee (STC) as part of its responsibilities to the LANS Board of Governors. LANL has defined fourteen STE capabilities. Table 1 lists the five STE capabilities that LANL Management (Director, PADSTE, technical Associate Directors) have identified for review in Fiscal Year (FY) 2009.« less

2012-11-01
Because health-related quality of life among blue-collar workers has not been well studied, the purpose of this study was to determine factors associated with health-related quality of life among Operating Engineers. With cross-sectional data from a convenience sample of 498 Operating Engineers, personal and health behavioral factors associated with health-related quality of life were examined. Multivariate linear regression analysis revealed that personal factors (older age, being married, more medical comorbidities, and depression) and behavioral factors (smoking, low fruit and vegetable intake, low physical activity, high body mass index, and low sleep quality) were associated with poor health-related quality of life. Operating Engineers are at risk for poor health-related quality of life. Underlying medical comorbidities and depression should be well managed. Worksite wellness programs addressing poor health behaviors may be beneficial.

Scientific research relies on computer software, yet software is not always developed following practices that ensure its quality and sustainability. This manuscript does not aim to propose new software development best practices, but rather to provide simple recommendations that encourage the adoption of existing best practices. Software development best practices promote better quality software, and better quality software improves the reproducibility and reusability of research. These recommendations are designed around Open Source values, and provide practical suggestions that contribute to making research software and its source code more discoverable, reusable and transparent. This manuscript is aimed at developers, but also at organisations, projects, journals and funders that can increase the quality and sustainability of research software by encouraging the adoption of these recommendations.

Systematic review of health-related quality of life models
2012-01-01
Background A systematic literature review was conducted to (a) identify the most frequently used health-related quality of life (HRQOL) models and (b) critique those models. Methods Online search engines were queried using pre-determined inclusion and exclusion criteria. We reviewed titles, abstracts, and then full-text articles for their relevance to this review. Then the most commonly used models were identified, reviewed in tables, and critiqued using published criteria. Results Of 1,602 titles identified, 100 articles from 21 countries met the inclusion criteria. The most frequently used HRQOL models were: Wilson and Cleary (16%), Ferrans and colleagues (4%), or World Health Organization (WHO) (5%). Ferrans and colleagues’ model was a revision of Wilson and Cleary’s model and appeared to have the greatest potential to guide future HRQOL research and practice. Conclusions Recommendations are for researchers to use one of the three common HRQOL models unless there are compelling and clearly delineated reasons for creating new models. Disease-specific models can be derived from one of the three commonly used HRQOL models. We recommend Ferrans and colleagues’ model because they added individual and environmental characteristics to the popular Wilson and Cleary model to better explain HRQOL. Using a common HRQOL model across studies will promote a coherent body of evidence that will more quickly advance the science in the area of HRQOL. PMID:23158687

Objectives To assess whether reports from reviewers recommended by authors show a bias in quality and recommendation for editorial decision, compared with reviewers suggested by other parties, and whether reviewer reports for journals operating on open or single-blind peer review models differ with regard to report quality and reviewer recommendations. Design Retrospective analysis of the quality of reviewer reports using an established Review Quality Instrument, and analysis of reviewer recommendations and author satisfaction surveys. Setting BioMed Central biology and medical journals. BMC Infectious Diseases and BMC Microbiology are similar in size, rejection rates, impact factors and editorial processes, but the former uses open peer review while the latter uses single-blind peer review. The Journal of Inflammation has operated under both peer review models. Sample Two hundred reviewer reports submitted to BMC Infectious Diseases, 200 reviewer reports submitted to BMC Microbiology and 400 reviewer reports submitted to the Journal of Inflammation. Results For each journal, author-suggested reviewers provided reports of comparable quality to non-author-suggested reviewers, but were significantly more likely to recommend acceptance, irrespective of the peer review model (p<0.0001 for BMC Infectious Diseases, BMC Microbiology and the Journal of Inflammation). For BMC Infectious Diseases, the overall quality of reviewer reports measured by the Review Quality Instrument was 5% higher than for BMC Microbiology (p=0.042). For the Journal of Inflammation, the quality of reports was the same irrespective of the peer review model used. Conclusions Reviewers suggested by authors provide reports of comparable quality to non-author-suggested reviewers, but are significantly more likely to recommend acceptance. Open peer review reports for BMC Infectious Diseases were of higher quality than single-blind reports for BMC Microbiology. There was no difference in quality of peer review in the Journal of Inflammation under open peer review compared with single blind. PMID:26423855

Hoover, Marcey L.; Kolb, Rachel R.
2014-03-01
In high-consequence engineering organizations, such as Sandia, quality assurance may be heavily dependent on staff competency. Competency-dependent quality assurance models are at risk when the environment changes, as it has with increasing attrition rates, budget and schedule cuts, and competing program priorities. Risks in Sandia's competency-dependent culture can be mitigated through changes to hiring, training, and customer engagement approaches to manage people, partners, and products. Sandia's technical quality engineering organization has been able to mitigate corporate-level risks by driving changes that benefit all departments, and in doing so has assured Sandia's commitment to excellence in high-consequence engineering and national service.

The quality and readability of internet information regarding clavicle fractures.
Zhang, Dafang; Schumacher, Charles; Harris, Mitchel Byron
2016-03-01
The internet has become a major source of health information for patients. However, there has been little scrutiny of health information available on the internet to the public. Our objectives were to evaluate the quality and readability of information available on the internet regarding clavicle fractures and whether they changed with academic affiliation of the website or with complexity of the search term. Through a prospective evaluation of 3 search engines using 3 different search terms of varying complexity ("broken collarbone," "collarbone fracture," and "clavicle fracture"), we evaluated 91 website hits for quality and readability. Websites were specifically analyzed by search term and by website type. Information quality was evaluated on a four-point scale, and information readability was assessed using the Flesch-Kincaid score for reading grade level. The average quality score for our website hits was low, and the average reading grade level was far above the recommended level. Academic websites offered significantly higher quality information, whereas commercial websites offered significantly lower quality information. The use of more complex search terms yielded information of higher reading grade level but not higher quality. Current internet information regarding clavicle fractures is of low quality and low readability. Higher quality information utilizing more accessible language on clavicle fractures is needed on the internet. It is important to be aware of the information accessible to patients prior to their presentation to our clinics. Patients should be advised to visit websites with academic affiliations and to avoid commercial websites. Copyright © 2015 The Japanese Orthopaedic Association. Published by Elsevier B.V.

BACKGROUND: Increasing use of gastrointestinal endoscopy, particularly for colorectal cancer screening, and increasing emphasis on health care quality, highlight the need for clearly defined, evidence-based processes to support quality improvement in endoscopy. OBJECTIVE: To identify processes and indicators of quality and safety relevant to high-quality endoscopy service delivery. METHODS: A multidisciplinary group of 35 voting participants developed recommendation statements and performance indicators. Systematic literature searches generated 50 initial statements that were revised iteratively following a modified Delphi approach using a web-based evaluation and voting tool. Statement development and evidence evaluation followed the AGREE (Appraisal of Guidelines, REsearch and Evaluation) and GRADE (Grading of Recommendations, Assessment, Development and Evaluation) guidelines. At the consensus conference, participants voted anonymously on all statements using a 6-point scale. Subsequent web-based voting evaluated recommendations for specific, individual quality indicators, safety indicators and mandatory endoscopy reporting fields. Consensus was defined a priori as agreement by 80% of participants. RESULTS: Consensus was reached on 23 recommendation statements addressing the following: ethics (statement 1: agreement 100%), facility standards and policies (statements 2 to 9: 90% to 100%), quality assurance (statements 10 to 13: 94% to 100%), training, education, competency and privileges (statements 14 to 19: 97% to 100%), endoscopy reporting standards (statements 20 and 21: 97% to 100%) and patient perceptions (statements 22 and 23: 100%). Additionally, 18 quality indicators (agreement 83% to 100%), 20 safety indicators (agreement 77% to 100%) and 23 recommended endoscopy-reporting elements (agreement 91% to 100%) were identified. DISCUSSION: The consensus process identified a clear need for high-quality clinical and outcomes research to support quality improvement in the delivery of endoscopy services. CONCLUSIONS: The guidelines support quality improvement in endoscopy by providing explicit recommendations on systematic monitoring, assessment and modification of endoscopy service delivery to yield benefits for all patients affected by the practice of gastrointestinal endoscopy.

The objective of this article was to critically review 2 prominent approaches used to grade the quality of evidence and the strength of recommendations. Every year much information becomes available as a result of publication of scientific papers, and clinicians should be able to assess current evidence so they, along with their patients, can make the most appropriate clinical decisions. This is particularly important when there is little or no high-quality evidence available about the subject of interest. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) and the Strength of Recommendation Taxonomy (SORT) were evaluated. Strengths and weaknesses of these 2 systems are discussed, mainly on the basis of their relevance to clinical dentistry. The conclusion was that use of a system for grading the quality of evidence and the strength of recommendations is urgently required because of the great heterogeneity of the quality and type of evidence relating to many dental procedures. Use of such a system will enable clinicians and their patients to make more informed decisions.

Future directions for the development of virtual reality within an automotive manufacturer.
Lawson, Glyn; Salanitri, Davide; Waterfield, Brian
2016-03-01
Virtual Reality (VR) can reduce time and costs, and lead to increases in quality, in the development of a product. Given the pressure on car companies to reduce time-to-market and to continually improve quality, the automotive industry has championed the use of VR across a number of applications, including design, manufacturing, and training. This paper describes interviews with 11 engineers and employees of allied disciplines from an automotive manufacturer about their current physical and virtual properties and processes. The results guided a review of research findings and scientific advances from the academic literature, which formed the basis of recommendations for future developments of VR technologies and applications. These include: develop a greater range of virtual contexts; use multi-sensory simulation; address perceived differences between virtual and real cars; improve motion capture capabilities; implement networked 3D technology; and use VR for market research.

Introduction: Poor data quality can be a serious threat to the validity and generalizability of clinical research findings. The growing availability of electronic administrative and clinical data is accompanied by a growing concern about the quality of these data for observational research and other analytic purposes. Currently, there are no widely accepted guidelines for reporting quality results that would enable investigators and consumers to independently determine if a data source is fit for use to support analytic inferences and reliable evidence generation. Model and Methods: We developed a conceptual model that captures the flow of data from data originator across successive data stewards and finally to the data consumer. This “data lifecycle” model illustrates how data quality issues can result in data being returned back to previous data custodians. We highlight the potential risks of poor data quality on clinical practice and research results. Because of the need to ensure transparent reporting of a data quality issues, we created a unifying data-quality reporting framework and a complementary set of 20 data-quality reporting recommendations for studies that use observational clinical and administrative data for secondary data analysis. We obtained stakeholder input on the perceived value of each recommendation by soliciting public comments via two face-to-face meetings of informatics and comparative-effectiveness investigators, through multiple public webinars targeted to the health services research community, and with an open access online wiki. Recommendations: Our recommendations propose reporting on both general and analysis-specific data quality features. The goals of these recommendations are to improve the reporting of data quality measures for studies that use observational clinical and administrative data, to ensure transparency and consistency in computing data quality measures, and to facilitate best practices and trust in the new clinical discoveries based on secondary use of observational data.

In all, 40 canals consisting of four different shapes in terms of angle and position of curvature were prepared by a combination of NT Engine and McXim instruments using the technique recommended by the manufacturer. Part 1 of this two-part report describes the efficacy of the instruments in terms of preparation time, instrument failure, canal blockages, loss of canal length and three-dimensional canal form. Overall, the mean preparation time for all canals was 6.01 min, with canal shape having a significant effect (P < 0.01) on the speed of preparation. One instrument fractured and only four instruments deformed, with most of the failures occurring in canals with curves which began 12 mm from the orifice, that is, in short acute curves. None of the canals became blocked with debris. Following preparation, 20 canals retained their original working length but 19 lost length and one gained in length; there were significant differences (P < 0.05) between the canal shapes in terms of mean loss of distance and in the category of distance change. Apical stops as determined from intracanal impressions were present in 37 of the canals; 16 were judged to be of good quality and 21 of poor quality. The canals were found to be smooth in the apical half of the canal in 33 specimens and in the coronal half of 39 specimens. All canals had good taper characteristics and 35 had good flow characteristics. Under the conditions of this study, NT Engine and McXim instruments prepared canals rapidly, with few deformations, no canal blockages and with minimal change in working length. The three-dimensional form of the canals demonstrated good flow and taper characteristics.

This manuscript presents the author's engineering and management experience during his internship in the Materials and Pavements (M&P) Division at the Texas A&M Transportation Institute (TTI), and is a record of study for the Doctor of Engineering at Texas A&M University. Through this internship, he met his established internship objectives of gaining technical knowledge as well as knowledge and skills in project management, organizational communication, and quality management of pavement condition data, and of attaining professional development. In meeting these objectives, the author describes the history, mission, and organizational structure of his workplace. He also presents his experience of developing and delivering a two-week training course on pavement design and construction in Kosovo. Participating in a number of professional development training courses and other activities prepared him for working as an engineering manager. These activities include Delta-T leadership training, an instructor development course, a time management and organizational skills course, and the M&P Division lecture series. Leadership and skills learned through the Delta-T program were beneficial for the employee as well as the employer. For the class project, the author and his teammates performed a study dealing with improving TTI's deliverables. The Delta-T team composed a report summarizing their efforts of examining the current state of TTI's project deliverables, the deliverables' shortcomings, and potential enhancements to expand the deliverables' appeal to additional types of potential users outside the traditional research community. The team also developed a prototype web-based model of deliverables and presented some implementation recommendations. Participating in the Texas Department of Transportation's (TxDOT's) pavement surface distress data collection program enabled the author to become familiar with pavement distress data quality management and thus attain the technical and nontechnical skills required for project management. He noticed some areas for improvement in TxDOT's rater's manual, rater's training class, and acceptance criteria for visual distress data.

In recent years there has been increasing interest in engineering education at the K-12 level, which has resulted in states adopting engineering standards as a part of their academic science standards. From a national perspective, the basis for research into engineering education at the K-12 level is the belief that it is of benefit to student learning, including to "improve student learning and achievement in science and mathematics; increase awareness of engineering and the work of engineers; boost youth interest in pursuing engineering as a career; and increase the technological literacy of all students" (National Research Council, 2009a, p. 1). The above has led to a need to understand how teachers are currently implementing engineering education in their classrooms. High school physics teachers have a history of implementing engineering design projects in their classrooms, thus providing an appropriate setting to look for evidence of quality engineering education at the high school level. Understanding the characteristics of quality engineering integration can inform curricular and professional development efforts for teachers asked to implement engineering in their classrooms. Thus, the question that guided this study is: How, and to what extent, do physics teachers represent quality engineering in a physics unit focused on engineering? A case study research design was implemented for this project. Three high school physics teachers were participants in this study focused on the integration of engineering education into the physics classroom. The data collected included observations, interviews, and classroom documents that were analyzed using the Framework for Quality K-12 Engineering Education (Moore, Glancy et al., 2013). The results provided information about the areas of the K-12 engineering framework addressed during these engineering design projects, and detailed the quality of these lesson components. The results indicate that all of the design projects contained components of the indicators central to engineering education, although with varied degrees of success. In addition, each design project contained aspects important to the development of students' understanding of engineering and that promote important professional skills used by engineers. The implications of this work are discussed at the teacher, school, professional development, and policy levels.

AS9100 has little to say about how to apply a Quality Management System (QMS) to aerospace test programs. There is little in the quality engineering Body of Knowledge that applies to testing, unless it is nondestructive examination or some type of lab or bench testing. If one examines how the systems engineering processes are implemented throughout a test program; and how these processes can be mapped to AS9100, a number of areas for involvement of the quality professional are revealed.

In this paper, we review the literature on nursing workload in intensive care units (ICUs) and its impact on patient safety and quality of working life of nurses. We then propose a conceptual framework of ICU nursing workload that defines causes, consequences and outcomes of workload. We identified four levels of nursing workload (ICU/unit level, job level, patient level, and situation level), and discuss measures associated with each of the four levels. A micro-level approach to ICU nursing workload at the situation level is proposed and recommended in order to reduce workload and mitigate its negative impact. Performance obstacles are conceptualized as causes of ICU nursing workload at the situation level.

Cost and Performance System (CAPS) is an automated system used from the planning phase through implementation to analysis and documentation. Data is retrievable or available for analysis of cost versus performance anomalies. CAPS provides a uniform system across intra- and international elements. A common system is recommended throughout an entire cost or profit center. Data can be easily accumulated and aggregated into higher levels of tracking and reporting of cost and performance.The level and quality of performance or productivity is indicated in the CAPS model and its process. The CAPS model provides the necessary decision information and insight to the principal investigator/project engineer for a successful project management experience. CAPS provides all levels of management with the appropriate detailed level of data.

Animal experiments remain essential to understand the fundamental mechanisms underpinning malignancy and to discover improved methods to prevent, diagnose and treat cancer. Excellent standards of animal care are fully consistent with the conduct of high quality cancer research. Here we provide updated guidelines on the welfare and use of animals in cancer research. All experiments should incorporate the 3Rs: replacement, reduction and refinement. Focusing on animal welfare, we present recommendations on all aspects of cancer research, including: study design, statistics and pilot studies; choice of tumour models (e.g., genetically engineered, orthotopic and metastatic); therapy (including drugs and radiation); imaging (covering techniques, anaesthesia and restraint); humane endpoints (including tumour burden and site); and publication of best practice.

Preliminary evaluation of the feasibility of artificial recharge in northern Qater
Vecchioli, John
1976-01-01
Fresh ground water in northern Qatar occurs as a lens in limestone and dolomite of Eocene age. Natural recharge from precipitation averages 17x106 cubic metres per year whereas current discharge averages 26.6x106 cubic metres per year. Depletion of storage is accompanied by a deterioration in quality due to encroachment of salty water from the Gulf and from underlying formations. Artificial recharge with desalted sea water to permit additional agricultural development appears technically feasible but its practicability needs to be examined further. A hydrogeological appraisal including test drilling, geophysical logging, pumping tests, and a recharge test, coupled with engineering analysis of direct surface storage/distribution of desalted sea water versus aquifer storage/distribution, is recommended.

The utility of biomedical information retrieval environments can be severely limited when users lack expertise in constructing effective search queries. To address this issue, we developed a computer-based query recommendation algorithm that suggests semantically interchangeable terms based on an initial user-entered query. In this study, we assessed the value of this approach, which has broad applicability in biomedical information retrieval, by demonstrating its application as part of a search engine that facilitates retrieval of information from electronic health records (EHRs). The query recommendation algorithm utilizes MetaMap to identify medical concepts from search queries and indexed EHR documents. Synonym variants from UMLS are used to expand the concepts along with a synonym set curated from historical EHR search logs. The empirical study involved 33 clinicians and staff who evaluated the system through a set of simulated EHR search tasks. User acceptance was assessed using the widely used technology acceptance model. The search engine's performance was rated consistently higher with the query recommendation feature turned on vs. off. The relevance of computer-recommended search terms was also rated high, and in most cases the participants had not thought of these terms on their own. The questions on perceived usefulness and perceived ease of use received overwhelmingly positive responses. A vast majority of the participants wanted the query recommendation feature to be available to assist in their day-to-day EHR search tasks. Challenges persist for users to construct effective search queries when retrieving information from biomedical documents including those from EHRs. This study demonstrates that semantically-based query recommendation is a viable solution to addressing this challenge. Published by Elsevier Inc.

Walsh, Kevin R.
1992-01-01
A flight evaluation as conducted to determine the effect of engine throttle response characteristics on precision formation-flying qualities. A variable electronic throttle control system was developed and flight-tested on a TF-104G airplane with a J79-11B engine at the NASA Dryden Flight Research Facility. Ten research flights were flown to evaluate the effects of throttle gain, time delay, and fuel control rate limiting on engine handling qualities during a demanding precision wing formation task. Handling quality effects of lag filters and lead compensation time delays were also evaluated. Data from pilot ratings and comments indicate that throttle control system time delays and rate limits cause significant degradations in handling qualities. Threshold values for satisfactory (level 1) and adequate (level 2) handling qualities of these key variables are presented.

Garcia, Inma; Sebastia, Laura; Onaindia, Eva; Guzman, Cesar
This paper introduces a method for giving recommendations of tourist activities to a group of users. This method makes recommendations based on the group tastes, their demographic classification and the places visited by the users in former trips. The group recommendation is computed from individual personal recommendations through the use of techniques such as aggregation, intersection or incremental intersection. This method is implemented as an extension of the e-Tourism tool, which is a user-adapted tourism and leisure application, whose main component is the Generalist Recommender System Kernel (GRSK), a domain-independent taxonomy-driven search engine that manages the group recommendation.

The Internet is a widely used source of information for patients searching for medical/health care information. While many studies have assessed existing medical/health care information on the Internet, relatively few have examined methods for design and delivery of such websites, particularly those aimed at the general public. This study describes a method of evaluating material for new medical/health care websites, or for assessing those already in existence, which is correlated with higher rankings on Google's Search Engine Results Pages (SERPs). A website quality assessment (WQA) tool was developed using criteria related to the quality of the information to be contained in the website in addition to an assessment of the readability of the text. This was retrospectively applied to assess existing websites that provide information about generic medicines. The reproducibility of the WQA tool and its predictive validity were assessed in this study. The WQA tool demonstrated very high reproducibility (intraclass correlation coefficient=0.95) between 2 independent users. A moderate to strong correlation was found between WQA scores and rankings on Google SERPs. Analogous correlations were seen between rankings and readability of websites as determined by Flesch Reading Ease and Flesch-Kincaid Grade Level scores. The use of the WQA tool developed in this study is recommended as part of the design phase of a medical or health care information provision website, along with assessment of readability of the material to be used. This may ensure that the website performs better on Google searches. The tool can also be used retrospectively to make improvements to existing websites, thus, potentially enabling better Google search result positions without incurring the costs associated with Search Engine Optimization (SEO) professionals or paid promotion.

Study Design An Internet-based evaluation of Web sites regarding lumbar fusion. Objective The Internet has become a major resource for patients; however, the quality and readability of Internet information regarding lumbar fusion is unclear. The objective of this study is to evaluate the quality and readability of Internet information regarding lumbar fusion and to determine whether these measures changed with Web site modality, complexity of the search term, or Health on the Net Code of Conduct certification. Methods Using five search engines and three different search terms of varying complexity (“low back fusion,” “lumbar fusion,” and “lumbar arthrodesis”), we identified and reviewed 153 unique Web site hits for information quality and readability. Web sites were specifically analyzed by search term and Web site modality. Information quality was evaluated on a 5-point scale. Information readability was assessed using the Flesch-Kincaid score for reading grade level. Results The average quality score was low. The average reading grade level was nearly six grade levels above that recommended by National Work Group on Literacy and Health. The quality and readability of Internet information was significantly dependent on Web site modality. The use of more complex search terms yielded information of higher reading grade level but not higher quality. Conclusions Higher-quality information about lumbar fusion conveyed using language that is more readable by the general public is needed on the Internet. It is important for health care providers to be aware of the information accessible to patients, as it likely influences their decision making regarding care. PMID:26933614

The current situation, bottleneck problems and severe challenges in quality control technology of Chinese Medicine (CM) are briefly described. It is presented to change the phenomenon related to the post-test as the main means and contempt for process control in drug regulation, reverse the situation of neglecting the development of process control and management technology for pharmaceutical manufacture and reconstruct the technological system for quality control of CM products. The regulation and technology system based on process control and management for controlling CM quality should be established to solve weighty realistic problems of CM industry from the root causes, including backwardness of quality control technology, weakness of quality risk control measures, poor reputation of product quality and so on. By this way, the obstacles from poor controllability of CM product quality could be broken. Concentrating on those difficult problems and weak links in the technical field of CM quality control, it is proposed to build CMC (Chemistry, Manufacturing and Controls) regulation for CM products with Chinese characteristics and promote the regulation international recognition as soon as possible. The CMC technical framework, which is clinical efficacy-oriented, manufacturing manner-centered and process control-focused, was designed. To address the clinical characteristics of traditional Chinese medicine (TCM) and the production feature of CM manufacture, it is suggested to establish quality control engineering for CM manufacturing by integrating pharmaceutical analysis, TCM chemistry, TCM pharmacology, pharmaceutical engineering, control engineering, management engineering and other disciplines. Further, a theoretical model of quality control engineering for CM manufacturing and the methodology of digital pharmaceutical engineering are proposed. A technology pathway for promoting CM standard and realizing the strategic goal of CM internationalization is elaborated. Copyright© by the Chinese Pharmaceutical Association.
The GRADE approach and Bradford Hill's criteria for causation.
Schünemann, Holger; Hill, Suzanne; Guyatt, Gordon; Akl, Elie A; Ahmed, Faruque
2011-05-01
This article describes how the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to grading the quality of evidence and strength of recommendations considers the Bradford Hill criteria for causation and how GRADE may relate to questions in public health. A primary concern in public health is that evidence from non-randomised studies may provide a more adequate or best available measure of a public health strategy's impact, but that such evidence might be graded as lower quality in the GRADE framework. GRADE, however, presents a framework that describes both criteria for assessing the quality of research evidence and the strength of recommendations that includes considerations arising from the Bradford Hill criteria. GRADE places emphasis on recommendations and in assessing quality of evidence; GRADE notes that randomisation is only one of many relevant factors. This article describes how causation may relate to developing recommendations and how the Bradford Hill criteria are considered in GRADE, using examples from the public health literature with a focus on immunisation.

This dissertation introduces a theory of information quality to explain macroscopic behavior observed in the systems engineering process. The theory extends principles of Shannon's mathematical theory of communication [1948] and statistical mechanics to information development processes concerned with the flow, transformation, and meaning of information. The meaning of requirements information in the systems engineering context is estimated or measured in terms of the cumulative requirements quality Q which corresponds to the distribution of the requirements among the available quality levels. The requirements entropy framework (REF) implements the theory to address the requirements engineering problem. The REF defines the relationship between requirements changes, requirements volatility, requirements quality, requirements entropy and uncertainty, and engineering effort. The REF is evaluated via simulation experiments to assess its practical utility as a new method for measuring, monitoring and predicting requirements trends and engineering effort at any given time in the process. The REF treats the requirements engineering process as an open system in which the requirements are discrete information entities that transition from initial states of high entropy, disorder and uncertainty toward the desired state of minimum entropy as engineering effort is input and requirements increase in quality. The distribution of the total number of requirements R among the N discrete quality levels is determined by the number of defined quality attributes accumulated by R at any given time. Quantum statistics are used to estimate the number of possibilities P for arranging R among the available quality levels. The requirements entropy H R is estimated using R, N and P by extending principles of information theory and statistical mechanics to the requirements engineering process. The information I increases as HR and uncertainty decrease, and the change in information AI needed to reach the desired state of quality is estimated from the perspective of the receiver. The HR may increase, decrease or remain steady depending on the degree to which additions, deletions and revisions impact the distribution of R among the quality levels. Current requirements trend metrics generally treat additions, deletions and revisions the same and simply measure the quantity of these changes over time. The REF evaluates the quantity of requirements changes over time, distinguishes between their positive and negative effects by calculating their impact on HR, Q, and AI, and forecasts when the desired state will be reached, enabling more accurate assessment of the status and progress of the requirements engineering effort. Results from random variable simulations suggest the REF is an improved leading indicator of requirements trends that can be readily combined with current methods. The increase in I, or decrease in H R and uncertainty, is proportional to the engineering effort E input into the requirements engineering process. The REF estimates the AE needed to transition R from their current state of quality to the desired end state or some other interim state of interest. Simulation results are compared with measured engineering effort data for Department of Defense programs published in the SE literature, and the results suggest the REF is a promising new method for estimation of AE.

To address low human papillomavirus (HPV) vaccination coverage, the American Academy of Family Physicians (AAFP) and the American Academy of Pediatrics (AAP) have launched national campaigns encouraging physicians to deliver strong HPV vaccine recommendations. We surveyed family physicians and pediatricians to examine the impact of these efforts on physicians' recommendation practices. A national sample of family physicians and pediatricians (n = 776) completed our online survey in 2014. The survey assessed reach, content, and influence of AAFP and AAP communications about HPV vaccination. The survey also assessed quality of physicians' communication practices for recommending HPV vaccination. Forty-seven percent of family physicians reported receiving information on HPV vaccination from AAFP, whereas 62% of pediatricians reported receiving information from AAP. Among physicians reached by AAFP or AAP, most reported receiving the message to give strong recommendations to adolescent boys (71%) and girls (78%). Although receiving information was not associated with HPV vaccine recommendation quality, receiving the message to give strong recommendations correlated with delivering higher-quality recommendations for boys (odds ratio, 4.19, 95% confidence interval, 2.64-6.64) and girls (odds ratio, 3.15, 95% confidence interval, 1.91-5.18). Over half of physicians reported improving their HPV vaccine communication after receiving information from AAFP (69%) or AAP (53%). Our findings suggest that it is important for AAFP and AAP to communicate the need for strong HPV vaccine recommendations. Given that many physicians reported improving their recommendation practices, professional organizations stand to contribute to increasing HPV vaccination coverage, but they will likely need to increase the intensity of quality improvement efforts to do so.

The American Pain Society (APS) set out to revise and expand its 1995 Quality Improvement Guidelines for the Treatment of Acute Pain and Cancer Pain and to facilitate improvements in the quality of pain management in all care settings. Eleven multidisciplinary members of the APS with expertise in quality improvement or measurement participated in the update. Five experts from organizations that focus on health care quality reviewed the final recommendations. MEDLINE and Cumulative Index to Nursing and Allied Health Literature databases were searched (1994-2004) to identify articles on pain quality measurement and quality improvement published after the development of the 1995 guidelines. The APS task force revised and expanded recommendations on the basis of the systematic review of published studies. The more than 3000 members of the APS were invited to provide input, and the 5 experts provided additional comments. The task force synthesized reviewers' comments into the final set of recommendations. The recommendations specify that all care settings formulate structured, multilevel systems approaches (sensitive to the type of pain, population served, and setting of care) that ensure prompt recognition and treatment of pain, involvement of patients and families in the pain management plan, improved treatment patterns, regular reassessment and adjustment of the pain management plan as needed, and measurement of processes and outcomes of pain management. Efforts to improve the quality of pain management must move beyond assessment and communication of pain to implementation and evaluation of improvements in pain treatment that are timely, safe, evidence based, and multimodal.

To assess whether reports from reviewers recommended by authors show a bias in quality and recommendation for editorial decision, compared with reviewers suggested by other parties, and whether reviewer reports for journals operating on open or single-blind peer review models differ with regard to report quality and reviewer recommendations. Retrospective analysis of the quality of reviewer reports using an established Review Quality Instrument, and analysis of reviewer recommendations and author satisfaction surveys. BioMed Central biology and medical journals. BMC Infectious Diseases and BMC Microbiology are similar in size, rejection rates, impact factors and editorial processes, but the former uses open peer review while the latter uses single-blind peer review. The Journal of Inflammation has operated under both peer review models. Two hundred reviewer reports submitted to BMC Infectious Diseases, 200 reviewer reports submitted to BMC Microbiology and 400 reviewer reports submitted to the Journal of Inflammation. For each journal, author-suggested reviewers provided reports of comparable quality to non-author-suggested reviewers, but were significantly more likely to recommend acceptance, irrespective of the peer review model (p<0.0001 for BMC Infectious Diseases, BMC Microbiology and the Journal of Inflammation). For BMC Infectious Diseases, the overall quality of reviewer reports measured by the Review Quality Instrument was 5% higher than for BMC Microbiology (p=0.042). For the Journal of Inflammation, the quality of reports was the same irrespective of the peer review model used. Reviewers suggested by authors provide reports of comparable quality to non-author-suggested reviewers, but are significantly more likely to recommend acceptance. Open peer review reports for BMC Infectious Diseases were of higher quality than single-blind reports for BMC Microbiology. There was no difference in quality of peer review in the Journal of Inflammation under open peer review compared with single blind. Published by the BMJ Publishing Group Limited.

Cumulative metal leaching from utilisation of secondary building materials in river engineering.
Leuven, R S E W; Willems, F H G
2004-01-01
The present paper estimates the utilisation of bulky wastes (minestone, steel slag, phosphorus slag and demolition waste) in hydraulic engineering structures in Dutch parts of the rivers Rhine, Meuse and Scheldt over the period 1980-2025. Although they offer several economic, technical and environmental benefits, these secondary building materials contain various metals that may leach into river water. A leaching model was used to predict annual emissions of arsenic, cadmium, copper, chromium, lead, mercury, nickel and zinc. Under the current utilisation and model assumptions, the contribution of secondary building materials to metal pollution in Dutch surface waters is expected to be relatively low compared to other sources (less than 0.1% and 0.2% in the years 2000 and 2025, respectively). However, continued and widespread large-scale applications of secondary building materials will increase pollutant leaching and may require further cuts to be made in emissions from other sources to meet emission reduction targets and water quality standards. It is recommended to validate available leaching models under various field conditions. Complete registration of secondary building materials will be required to improve input data for leaching models.
Towards Information Enrichment through Recommendation Sharing

Nowadays most existing recommender systems operate in a single organisational basis, i.e. a recommender system recommends items to customers of one organisation based on the organisation's datasets only. Very often the datasets of a single organisation do not have sufficient resources to be used to generate quality recommendations. Therefore, it would be beneficial if recommender systems of different organisations with similar nature can cooperate together to share their resources and recommendations. In this chapter, we present an Ecommerce-oriented Distributed Recommender System (EDRS) that consists of multiple recommender systems from different organisations. By sharing resources and recommendations with each other, these recommenders in the distributed recommendation system can provide better recommendation service to their users. As for most of the distributed systems, peer selection is often an important aspect. This chapter also presents a recommender selection technique for the proposed EDRS, and it selects and profiles recommenders based on their stability, average performance and selection frequency. Based on our experiments, it is shown that recommenders' recommendation quality can be effectively improved by adopting the proposed EDRS and the associated peer selection technique.

To systematically assess the quality of online information related to weight loss that Spanish speakers in the U.S. are likely to access. This study evaluated the accessibility and quality of information for websites that were identified from weight loss queries in Spanish and compared this with previously published results in English. The content was scored with respect to five dimensions: nutrition, physical activity, behavior, pharmacotherapy, and surgical recommendations. Sixty-six websites met eligibility criteria (21 commercial, 24 news/media, 10 blogs, 0 medical/government/university, 11 unclassified sites). Of 16 possible points, mean content quality score was 3.4 (SD = 2.0). Approximately 1.5% of sites scored greater than 8 (out of 12) on nutrition, physical activity, and behavior. Unsubstantiated claims were made on 94% of the websites. Content quality scores varied significantly by type of website (P < 0.0001) with unclassified websites scoring the highest (mean = 6.3, SD = 1.4) and blogs scoring the lowest (mean = 2.2, SD = 1.2). All content quality scores were lower for Spanish websites relative to English websites. Weight loss information accessed in Spanish Web searches is suboptimal and relatively worse than weight loss information accessed in English, suggesting that U.S. Spanish speakers accessing weight loss information online may be provided with incomplete and inaccurate information. © 2016 The Obesity Society.

Pulmonary vascular dysfunction, pulmonary hypertension (PH), and resulting right ventricular (RV) failure occur in many critical illnesses and may be associated with a worse prognosis. PH and RV failure may be difficult to manage: principles include maintenance of appropriate RV preload, augmentation of RV function, and reduction of RV afterload by lowering pulmonary vascular resistance (PVR). We therefore provide a detailed update on the management of PH and RV failure in adult critical care. A systematic review was performed, based on a search of the literature from 1980 to 2010, by using prespecified search terms. Relevant studies were subjected to analysis based on the GRADE method. Clinical studies of intensive care management of pulmonary vascular dysfunction were identified, describing volume therapy, vasopressors, sympathetic inotropes, inodilators, levosimendan, pulmonary vasodilators, and mechanical devices. The following GRADE recommendations (evidence level) are made in patients with pulmonary vascular dysfunction: 1) A weak recommendation (very-low-quality evidence) is made that close monitoring of the RV is advised as volume loading may worsen RV performance; 2) A weak recommendation (low-quality evidence) is made that low-dose norepinephrine is an effective pressor in these patients; and that 3) low-dose vasopressin may be useful to manage patients with resistant vasodilatory shock. 4) A weak recommendation (low-moderate quality evidence) is made that low-dose dobutamine improves RV function in pulmonary vascular dysfunction. 5) A strong recommendation (moderate-quality evidence) is made that phosphodiesterase type III inhibitors reduce PVR and improve RV function, although hypotension is frequent. 6) A weak recommendation (low-quality evidence) is made that levosimendan may be useful for short-term improvements in RV performance. 7) A strong recommendation (moderate-quality evidence) is made that pulmonary vasodilators reduce PVR and improve RV function, notably in pulmonary vascular dysfunction after cardiac surgery, and that the side-effect profile is reduced by using inhaled rather than systemic agents. 8) A weak recommendation (very-low-quality evidence) is made that mechanical therapies may be useful rescue therapies in some settings of pulmonary vascular dysfunction awaiting definitive therapy. This systematic review highlights that although some recommendations can be made to guide the critical care management of pulmonary vascular and right ventricular dysfunction, within the limitations of this review and the GRADE methodology, the quality of the evidence base is generally low, and further high-quality research is needed.

The SPARTA Embedded Expert System (SEES) is an intelligent health monitoring system that directs analysis by placing confidence factors on possible engine status and then recommends a course of action to an engineer or engine controller. The technique can prevent catastropic failures or costly rocket engine down time because of false alarms. Further, the SEES has potential as an on-board flight monitor for reusable rocket engine systems. The SEES methodology synergistically integrates vibration analysis, pattern recognition and communications theory techniques with an artificial intelligence technique - the Embedded Expert System (EES).

The neurology residency programs in the United States are facing a crisis of quality. The Association of University Professors of Neurology (AUPN) approved the Quality Improvement Committee to examine this situation and make recommendations, which have been accepted by the AUPN. The recommendations are (1) that the educational goals of neurology residency training be dissociated from patient-care needs in academic medical centers and (2) that minimum levels of quality be applied to residents in neurology residency programs and to these programs themselves. These minimum criteria should include minimum educational criteria for entry into the program, minimum criteria for advancement from one year to the next in the program, and minimum criteria for performance of the graduates of neurology residency programs for program accreditation. The implementation of these recommendations will require a shift of funding of the care of indigent patients from the graduate medical education budget to direct patient-care sources. These recommendations will significantly improve the quality of neurologists and neurologic care in the United States.

The maturing of the quality improvement paradigm in the SEL
NASA Technical Reports Server (NTRS)
Basili, Victor R.
1993-01-01
The Software Engineering Laboratory uses a paradigm for improving the software process and product, called the quality improvement paradigm. This paradigm has evolved over the past 18 years, along with our software development processes and product. Since 1976, when we first began the SEL, we have learned a great deal about improving the software process and product, making a great many mistakes along the way. Quality improvement paradigm, as it is currently defined, can be broken up into six steps: characterize the current project and its environment with respect to the appropriate models and metrics; set the quantifiable goals for successful project performance and improvement; choose the appropriate process model and supporting methods and tools for this project; execute the processes, construct the products, and collect, validate, and analyze the data to provide real-time feedback for corrective action; analyze the data to evaluate the current practices, determine problems, record findings, and make recommendations for future project improvements; and package the experience gained in the form of updated and refined models and other forms of structured knowledge gained from this and prior projects and save it in an experience base to be reused on future projects.
Sound quality assessment of Diesel combustion noise using in-cylinder pressure components
NASA Astrophysics Data System (ADS)
Payri, F.; Broatch, A.; Margot, X.; Monelletta, L.
2009-01-01
The combustion process in direct injection (DI) Diesel engines is an important source of noise, and it is thus the main reason why end-users could be reluctant to drive vehicles powered with this type of engine. This means that the great potential of Diesel engines for environment preservation—due to their lower consumption and the subsequent reduction of CO2 emissions—may be lost. Moreover, the advanced combustion concepts—e.g. the HCCI (homogeneous charge compression ignition)—developed to comply with forthcoming emissions legislation, while maintaining the efficiency of current engines, are expected to be noisier because they are characterized by a higher amount of premixed combustion. For this reason many efforts have been dedicated by car manufacturers in recent years to reduce the overall level and improve the sound quality of engine noise. Evaluation procedures are required, both for noise levels and sound quality, that may be integrated in the global engine development process in a timely and cost-effective manner. In previous published work, the authors proposed a novel method for the assessment of engine noise level. A similar procedure is applied in this paper to demonstrate the suitability of combustion indicators for the evaluation of engine noise quality. These indicators, which are representative of the peak velocity of fuel burning and the resonance in the combustion chamber, are well correlated with the combustion noise mark obtained from jury testing. Quite good accuracy in the prediction of the engine noise quality has been obtained with the definition of a two-component regression, which also permits the identification of the combustion process features related to the resulting noise quality, so that corrective actions may be proposed.

We propose a network and visual quality aware N-Screen content recommender system. N-Screen provides more ways than ever before to access multimedia content through multiple devices and heterogeneous access networks. The heterogeneity of devices and access networks present new questions of QoS (quality of service) in the realm of user experience with content. We propose, a recommender system that ensures a better visual quality on user's N-screen devices and the efficient utilization of available access network bandwidth with user preferences. The proposed system estimates the available bandwidth and visual quality on users N-Screen devices and integrates it with users preferences and contents genre information to personalize his N-Screen content. The objective is to recommend content that the user's N-Screen device and access network are capable of displaying and streaming with the user preferences that have not been supported in existing systems. Furthermore, we suggest a joint matrix factorization approach to jointly factorize the users rating matrix with the users N-Screen device similarity and program genres similarity. Finally, the experimental results show that we also enhance the prediction and recommendation accuracy, sparsity, and cold start issues. PMID:24982999

Objectives: The aims of the current study were to comprehensively assess the dietary intakes and diet quality of a sample of Australian competitive adolescent rugby union players and compare these intakes with National and Sports Dietitians Association (SDA) Recommendations for adolescent athletes. A secondary aim investigated applying different physical activity level (PAL) coefficients to determine total energy expenditure (TEE) in order to more effectively evaluate the adequacy of energy intakes. Design: Cross-sectional. Methods: Anthropometrics and dietary intakes were assessed in 25 competitive adolescent male rugby union players (14 to 18 years old). Diet was assessed using the validated Australian Eating Survey (AES) food frequency questionnaire and diet quality was assessed through the Australian Recommended Food Score. Results: The median dietary intakes of participants met national recommendations for percent energy (% E) from carbohydrate, protein and total fat, but not carbohydrate intake when evaluated as g/day as proposed in SDA guidelines. Median intakes of fibre and micronutrients including calcium and iron also met national recommendations. Overall diet quality was classified as ‘good’ with a median diet quality score of 34 (out of a possible 73); however, there was a lack of variety within key food groups including carbohydrates and proteins. Non-core food consumption exceeded recommended levels at 38% of the daily total energy intake, with substantial contributions from takeaway foods and sweetened beverages. A PAL coefficient of 1.2–1.4 was found to best balance the energy intakes of these players in their pre-season. Conclusions: Adolescent rugby players met the percent energy recommendations for macronutrients and attained an overall ‘good’ diet quality score. However, it was identified that when compared to specific recommendations for athletes, carbohydrate intakes were below recommendations and these players in their pre-season reported high consumption of non-core foods, particularly sugar sweetened drinks and low intakes of vegetables.

Clinical practice guidelines (CPGs) have been developed to provide health-care practitioners with the best possible evidence, but the quality of these CPGs varies greatly. The goal of this study was to systematically evaluate the quality of cough CPGs and identify gaps limiting evidence-based practice. Systematic searches were conducted to identify cough CPGs in guideline databases, developers' Websites, and Medline. Four reviewers independently evaluated eligible guidelines by using the Appraisal of Guidelines for Research and Evaluation II assessment tool. Agreement among reviewers was measured by using the intraclass correlation coefficient. The number of recommendations, strength of recommendation, and levels of evidence were determined. Fifteen cough CPGs were identified. An overall high degree of agreement among reviewers was observed (intraclass correlation coefficient, 0.82 [95% CI, 0.79-0.85]). The quality ranged from good to acceptable in the scope and purpose (mean, 72%; range, 54%-93%) and clarity and presentation (mean, 68%; range, 50%-90%) domains but not in stakeholder involvement (mean, 36%; range, 18%-90%), rigor of development (mean, 36%; range, 9%-93%), applicability (mean, 23%; range, 9%-83%), and editorial independence domains (mean, 24%; range, 0-96%). Seven guidelines (46.7%) were considered "strongly recommended" or "recommended with modifications" for clinical practice. More than 70% of recommendations were based on nonrandomized studies (Level C, 30.4%) and expert opinion (Level D, 41.3%). The quality of cough CPGs is variable, and recommendations are largely based on low-quality evidence. There is significant room for improvement to develop high-quality guidelines, which urgently warrants first-class research to minimize the vital gaps in the evidence for formulation of cough CPGs.

The results of a nine month study program on mass data storage technology for rocket engine (especially the Space Shuttle Main Engine) health monitoring and control are summarized. The program had the objective of recommending a candidate mass data storage technology development for rocket engine health monitoring and control and of formulating a project plan and specification for that technology development. The work was divided into three major technical tasks: (1) development of requirements; (2) survey of mass data storage technologies; and (3) definition of a project plan and specification for technology development. The first of these tasks reviewed current data storage technology and developed a prioritized set of requirements for the health monitoring and control applications. The second task included a survey of state-of-the-art and newly developing technologies and a matrix-based ranking of the technologies. It culminated in a recommendation of optical disk technology as the best candidate for technology development. The final task defined a proof-of-concept demonstration, including tasks required to develop, test, analyze, and demonstrate the technology advancement, plus an estimate of the level of effort required.

The paradigm shift in recent years towards sustainable and coherent water resources management on a river basin scale has changed the subject of investigations to a multi-scale problem representing a great challenge for all actors participating in the management process. In this regard, planning engineers often face an inherent conflict to provide reliable decision support for complex questions with a minimum of effort. This trend inevitably increases the risk to base decisions upon uncertain and unverified conclusions. This paper proposes an adaptive framework for integral planning that combines several concepts (flow balancing, water quality monitoring, process modelling, multi-objective assessment) to systematically evaluate management strategies for water quality improvement. As key element, an S/P matrix is introduced to structure the differentiation of relevant 'pressures' in affected regions, i.e. 'spatial units', which helps in handling complexity. The framework is applied to a small, but typical, catchment in Flanders, Belgium. The application to the real-life case shows: (1) the proposed approach is adaptive, covers problems of different spatial and temporal scale, efficiently reduces complexity and finally leads to a transparent solution; and (2) water quality and emission-based performance evaluation must be done jointly as an emission-based performance improvement does not necessarily lead to an improved water quality status, and an assessment solely focusing on water quality criteria may mask non-compliance with emission-based standards. Recommendations derived from the theoretical analysis have been put into practice.
Integrated software system for improving medical equipment management.
Bliznakov, Z; Pappous, G; Bliznakova, K; Pallikarakis, N
2003-01-01
The evolution of biomedical technology has led to an extraordinary use of medical devices in health care delivery. During the last decade, clinical engineering departments (CEDs) turned toward computerization and application of specific software systems for medical equipment management in order to improve their services and monitor outcomes. Recently, much emphasis has been given to patient safety. Through its Medical Device Directives, the European Union has required all member nations to use a vigilance system to prevent the reoccurrence of adverse events that could lead to injuries or death of patients or personnel as a result of equipment malfunction or improper use. The World Health Organization also has made this issue a high priority and has prepared a number of actions and recommendations. In the present workplace, a new integrated, Windows-oriented system is proposed, addressing all tasks of CEDs but also offering a global approach to their management needs, including vigilance. The system architecture is based on a star model, consisting of a central core module and peripheral units. Its development has been based on the integration of 3 software modules, each one addressing specific predefined tasks. The main features of this system include equipment acquisition and replacement management, inventory archiving and monitoring, follow up on scheduled maintenance, corrective maintenance, user training, data analysis, and reports. It also incorporates vigilance monitoring and information exchange for adverse events, together with a specific application for quality-control procedures. The system offers clinical engineers the ability to monitor and evaluate the quality and cost-effectiveness of the service provided by means of quality and cost indicators. Particular emphasis has been placed on the use of harmonized standards with regard to medical device nomenclature and classification. The system's practical applications have been demonstrated through a pilot evaluation trial.

Do Clinical Practice Guidelines Improve Quality?
Baldassari, Cristina M
2017-07-01
Controversy exists surrounding how to best define and assess quality in the health care setting. Clinical practice guidelines (CPGs) have been developed to improve the quality of medical care by highlighting key clinical recommendations based on recent evidence. However, data linking CPGs to improvements in outcomes in otolaryngology are lacking. Numerous barriers contribute to difficulties in translating CPGs to improvements in quality. Future initiatives are needed to improve CPG adherence and define the impact of CPG recommendations on the quality of otolaryngologic care provided to our patients.

In tissue engineering approaches, the quality of substitutes is a key element to determine its ability to treat cartilage defects. However, in clinical practice, the evaluation of tissue-engineered cartilage substitute quality is not possible due to the invasiveness of the standard procedure, which is to date histology. The aim of this work was to validate a new innovative system performed from two-photon excitation laser adapted to an optical macroscope to evaluate at macroscopic scale the collagen network in cartilage tissue-engineered substitutes in confrontation with gold standard histologic techniques or immunohistochemistry to visualize type II collagen. This system permitted to differentiate the quality of collagen network between ITS and TGF-β1 treatments. Multiscale large field imaging combined to multimodality approaches (SHG-TCSPC) at macroscopical scale represent an innovative and non-invasive technique to monitor the quality of collagen network in cartilage tissue-engineered substitutes before in vivo implantation.

To provide an up-to-date assessment of the quality of commonly recommended questionnaires for measuring symptom severity and quality of life in women with urinary incontinence and also to consider their application to practice. Urinary incontinence is a common problem for women. In addition to various physical symptoms, there is a known effect on quality of life. Psychometrically robust questionnaires are reported to be the best way to measure an individual's perceptions of symptom severity and quality of life, and a number of different ones are recommended for use in international and national guidance, which can be confusing for clinicians. Moreover, there are concerns over the applicability of some of these instruments in clinical practice. An evaluative review was carried out examining selected questionnaires measuring symptom severity and/or quality of life. Selection of questionnaires for inclusion in the review was based on the recommendations of evidence-based guidance, followed by systematic scrutiny of the characteristics of the individual recommended questionnaires. Thirteen questionnaires were included in the review, of which three appeared to 'outperform' the remainder in terms of their psychometric properties and other characteristics. This review provides the most up-to-date and comprehensive analysis of the quality and applicability of the included questionnaires and offers the practitioner advice on which to select for use in practice. This review aims to help the practitioner choose a questionnaire based on a sound evaluation of the quality of the questionnaire and its applicability to the clinical setting. © 2013 John Wiley & Sons Ltd.

The impact of fear appeals on processing and acceptance of action recommendations.
de Hoog, Natascha; Stroebe, Wolfgang; de Wit, John B F
2005-01-01
A stage model of processing of fear-arousing communications was tested in an experiment that examined the impact of vulnerability to a severe health risk, the quality of the arguments supporting a protective action recommendation, and the source to which the recommendation was attributed, on processing and acceptance of the recommendation. Argument quality influenced attitudes toward the recommendation (but not intention to act), and this effect was mediated by negative thoughts about the recommendation. Vulnerability influenced intention to act (but not attitudes), and this effect was mediated by perceived threat and positive thoughts about the recommendation. The pattern of findings suggests that although vulnerability to a severe health risk induces biased processing of the recommendation, biased processing is restricted to intentions and does not compromise the evaluation of the recommendation. The theoretical and practical implications of these findings are discussed.

The multiple dietary restrictions recommended to hemodialysis patients may be difficult to achieve and, at the same time, may result in nutritional deficiencies rendering a poor dietary quality. We here assess the dietary quality and adherence to renal-specific guideline recommendations among hemodialysis patients from a single center in Canary Islands, Spain. Cross-sectional study, including 91 patients undergoing maintenance hemodialysis. Clinical data and 3-day dietary records were collected. We compared patient's reported nutrients intake with guideline recommendations. We also evaluated their alignment with current American Heart Association dietary guidelines for cardiovascular prevention. Seventy-seven percent and 50% of patients consumed less than the recommended daily energy and protein, respectively. Although half of the patients met the recommendations for dietary fat intake, this was accounted by an excess of saturated fat in 92% of them. Only 22% consumed sufficient fiber. A very small proportion of patients (less than 50%) met the requirements for vitamins and other micronutrients. Insufficient dietary intake was observed in most patients for all vitamins except for cobalamin. Similarly, inadequate dietary intake was observed for many minerals, by both excess (phosphorus, calcium, sodium, and potassium) and defect (magnesium). Most patients met the recommendations for iron and zinc in their diets. A large proportion of hemodialysis patients at our center did not meet current renal-specific dietary recommendations. The quality of the diet was considered poor and proatherogenic according to American Heart Association guidelines. Copyright © 2016 National Kidney Foundation, Inc. Published by Elsevier Inc.

The breast cancer incidence in low and middle income countries (LMCs) is increasing globally, and patient outcomes are generally worse in these nations compared to high income countries (HICs). This is partly due to resource constraints associated with implementing recommended breast cancer therapies. Clinical practice guideline (CPG) adherence can improve breast cancer outcomes, however, many CPGs are created in HICs, and include costly recommendations that may not be feasible in LMCs. In addition, the quality of CPGs can be variable. The aim of this study was to perform a systematic review of CPGs on early breast cancer systemic therapy with potential international impact, to evaluate their content, quality, and resource sensitivity. A MEDLINE and gray literature search was completed for English language CPGs published between 2005 and 2010, and then updated to July 2014. Extracted guidelines were evaluated using the AGREE 2 instrument. Guidelines were specifically analyzed for resource sensitivity. Most of the extracted CPGs had similar recommendations with regards to systemic therapy. However, only one, the Breast Health Global Initiative, made recommendations with consideration of different global resources. Overall, the CPGs were of variable quality, and most scored poorly in the quality domain evaluating implementation barriers such as resources. Published CPGs for early breast cancer are created in HICs, have similar recommendations, and are generally resource-insensitive. Given the visibility and influence of these CPGs on LMCs, efforts to create higher quality, resource-sensitive guidelines with less redundancy are needed. Copyright © 2014 Elsevier Ltd.

The Joint Asia Diabetes Evaluation (JADE) Program is a web-based program incorporating a comprehensive risk engine, care protocols, and clinical decision support to improve ambulatory diabetes care. The JADE Program uses information technology to facilitate healthcare professionals to create a diabetes registry and to deliver an evidence-based care and education protocol tailored to patients' risk profiles. With written informed consent from participating patients and care providers, all data are anonymized and stored in a databank to establish an Asian Diabetes Database for research and publication purpose. The JADE electronic portal (e-portal: http://www.jade-adf.org) is implemented as a Java application using the Apache web server, the mySQL database and the Cocoon framework. The JADE e-portal comprises a risk engine which predicts 5-year probability of major clinical events based on parameters collected during an annual comprehensive assessment. Based on this risk stratification, the JADE e-portal recommends a care protocol tailored to these risk levels with decision support triggered by various risk factors. Apart from establishing a registry for quality assurance and data tracking, the JADE e-portal also displays trends of risk factor control at each visit to promote doctor-patient dialogues and to empower both parties to make informed decisions. The JADE Program is a prototype using information technology to facilitate implementation of a comprehensive care model, as recommended by the International Diabetes Federation. It also enables health care teams to record, manage, track and analyze the clinical course and outcomes of people with diabetes.

Architecture for fiber-optic sensors and actuators in aircraft propulsion systems
NASA Technical Reports Server (NTRS)
Glomb, W. L., Jr.
1990-01-01
This paper describes a design for fiber-optic sensing and control in advanced aircraft Electronic Engine Control (EEC). The recommended architecture is an on-engine EEC which contains electro-optic interface circuits for fiber-optic sensors. Size and weight are reduced by multiplexing arrays of functionally similar sensors on a pairs of optical fibers to common electro-optical interfaces. The architecture contains interfaces to seven sensor groups. Nine distinct fiber-optic sensor types were found to provide the sensing functions. Analysis revealed no strong discriminator (except reliability of laser diodes and remote electronics) on which to base a selection of preferred common interface type. A hardware test program is recommended to assess the relative maturity of the technologies and to determine real performance in the engine environment.

Comparing quality of care between large health care systems is important for health systems management. This study used measures of the quality of pharmacotherapy for patients with schizophrenia and compared these measures across a sample of patients from the Department of Veterans Affairs (VA) and the private sector. A random sample of all patients diagnosed with schizophrenia in the VA during fiscal year (FY) 2000 was identified using administrative data. In the private sector, a sample of patients diagnosed with schizophrenia in 2000 was identified using MEDSTAT's MarketScan database. For both groups, use of antipsychotic medications was studied and measures of the quality of pharmacotherapy were constructed, including whether patients were prescribed any antipsychotic medication, one of the newer atypical antipsychotics, and whether dosing adhered to established treatment recommendations. These measures were compared across the two groups using logistic regression models, controlling for age, gender, and comorbid diagnoses. Most patients with a diagnosis of schizophrenia (82% in the VA and 73% in the private sector) received an antipsychotic medication, usually one of the newer atypical drugs. Patients in the VA were more likely to be dosed above treatment recommendations, and less likely to be dosed below treatment recommendations. Overall, differences in proportion schizophrenia patients dosed according to recommendations were not statistically different across the two systems (60% in the VA, 58% in the private sector). Differences between the two systems were mixed, with the VA outperforming the private sector with respect to some measures and doing worse on others. Although the VA and the private sector were comparable with respect to the quality measures used in this study, there is room for improvement in both systems. Treatment recommendations are based on the best available clinical evidence of effectiveness and safety. Quality of care might be improved with better adherence to these recommendations. Relatively low rates of adherence to treatment recommendations may be due to lack of awareness of these recommendations among prescribing physicians, or a belief that the recommendations are inadequate. To the extent that low rates of adherence to treatment recommendations are caused by a lack of awareness among physicians, policies should be developed to disseminate this information and encourage the appropriate use of these medications. Further research is needed to understand physician prescribing decisions for these medications. To the extent that physicians feel treatment recommendations for these drugs are inadequate, further research is needed to refine the recommendations.

The objective of this study is to systematically assess the quality of existing patient-reported outcome measures developed and/or validated for Quality of Life measurement in bariatric surgery (BS) and body contouring surgery (BCS). We conducted a systematic literature search in PubMed, EMBASE, PsycINFO, CINAHL, Cochrane Database Systematic Reviews and CENTRAL identifying studies on measurement properties of BS and BCS Quality of Life instruments. For all eligible studies, we evaluated the methodological quality of the studies by using the COnsensus-based Standards for the selection of health Measurement INstruments checklist and the quality of the measurement instruments by applying quality criteria. Four degrees of recommendation were assigned to validated instruments (A-D). Out of 4,354 articles, a total of 26 articles describing 24 instruments were included. No instrument met all requirements (category A). Seven instruments have the potential to be recommended depending on further validation studies (category B). Of these seven, the BODY-Q has the strongest evidence for content validity in BS and BCS. Two instruments had poor quality in at least one required quality criterion (category C). Fifteen instruments were minimally validated (category D). The BODY-Q, developed for BS and BCS, possessed the strongest evidence for quality of measurement properties and has the potential to be recommended in future clinical trials. © 2018 The Authors.

Factors associated with sleep quality among operating engineers.

2013-06-01
Blue collar workers generally report high job stress and are exposed to loud noises at work and engage in many of risky health behavioral factors, all of which have been associated with poor sleep quality. However, sleep quality of blue collar workers has not been studied extensively, and no studies have focused Operating Engineers (heavy equipment operators) among whom daytime fatigue would place them at high risk for accidents. Therefore, the purpose of this study was to determine variables associated with sleep quality among Operating Engineers. This was a cross-sectional survey design with a dependent variable of sleep quality and independent variables of personal and related health behavioral factors. A convenience sample of 498 Operating Engineers was recruited from approximately 16,000 Operating Engineers from entire State of Michigan in 2008. Linear regression was used to determine personal and related health behavior factors associated with sleep quality. Multivariate analyses showed that personal factors related to poor sleep quality were younger age, female sex, higher pain, more medical comorbidities and depressive symptoms and behavioral factors related to poor sleep quality were nicotine dependence. While sleep scores were similar to population norms, approximately 34 % (n = 143) showed interest in health services for sleep problems. While many personal factors are not changeable, interventions to improve sleep hygiene as well as interventions to treat pain, depression and smoking may improve sleep quality resulting in less absenteeism, fatal work accidents, use of sick leave, work disability, medical comorbidities, as well as subsequent mortality.

The Radioisotope Power Systems Program of the Idaho National Laboratory makes an empirical case for a highly integrated Quality Assurance function pertaining to the preparation, assembly, testing, storage and transportation of 238Pu fueled radioisotope thermoelectric generators. Case data represents multiple campaigns including the Pluto/New Horizons mission,more » the Mars Science Laboratory mission in progress, and other related projects. Traditional Quality Assurance models would attempt to reduce cost by minimizing the role of dedicated Quality Assurance personnel in favor of either functional tasking or peer-based implementations. Highly integrated Quality Assurance adds value by placing trained quality inspectors on the production floor side-by-side with nuclear facility operators to enhance team dynamics, reduce inspection wait time, and provide for immediate, independent feedback. Value is also added by maintaining dedicated Quality Engineers to provide for rapid identification and resolution of corrective action, enhanced and expedited supply chain interfaces, improved bonded storage capabilities, and technical resources for requirements management including data package development and Certificates of Inspection. A broad examination of cost-benefit indicates highly integrated Quality Assurance can reduce cost through the mitigation of risk and reducing administrative burden thereby allowing engineers to be engineers, nuclear operators to be nuclear operators, and the cross-functional team to operate more efficiently. Applicability of this case extends to any high-value, long-term project where traceability and accountability are determining factors.« less
How Quality Improvement Practice Evidence Can Advance the Knowledge Base.
OʼRourke, Hannah M; Fraser, Kimberly D
2016-01-01
Recommendations for the evaluation of quality improvement interventions have been made in order to improve the evidence base of whether, to what extent, and why quality improvement interventions affect chosen outcomes. The purpose of this article is to articulate why these recommendations are appropriate to improve the rigor of quality improvement intervention evaluation as a research endeavor, but inappropriate for the purposes of everyday quality improvement practice. To support our claim, we describe the differences between quality improvement interventions that occur for the purpose of practice as compared to research. We then carefully consider how feasibility, ethics, and the aims of evaluation each impact how quality improvement interventions that occur in practice, as opposed to research, can or should be evaluated. Recommendations that fit the evaluative goals of practice-based quality improvement interventions are needed to support fair appraisal of the distinct evidence they produce. We describe a current debate on the nature of evidence to assist in reenvisioning how quality improvement evidence generated from practice might complement that generated from research, and contribute in a value-added way to the knowledge base.

My assertion is that not only are product lines a relevant research topic, but that the tools used by empirical software engineering researchers can address observed practical problems. Our experience at NASA has been there are often externally proposed solutions available, but that we have had difficulties applying them in our particular context. We have also focused on return on investment issues when evaluating product lines, and while these are important, one can not attain objective data on success or failure until several applications from a product family have been deployed. The use of the Quality Improvement Paradigm (QIP) can address these issues: (1) Planning an adoption path from an organization's current state to a product line approach; (2) Constructing a development process to fit the organization's adoption path; (3) Evaluation of product line development processes as the project is being developed. The QIP consists of the following six steps: (1) Characterize the project and its environment; (2) Set quantifiable goals for successful project performance; (3) Choose the appropriate process models, supporting methods, and tools for the project; (4) Execute the process, analyze interim results, and provide real-time feedback for corrective action; (5) Analyze the results of completed projects and recommend improvements; and (6) Package the lessons learned as updated and refined process models. A figure shows the QIP in detail. The iterative nature of the QIP supports an incremental development approach to product lines, and the project learning and feedback provide the necessary early evaluations.
Image quality specification and maintenance for airborne SAR

Clinard, Mark S.
2004-08-01
Specification, verification, and maintenance of image quality over the lifecycle of an operational airborne SAR begin with the specification for the system itself. Verification of image quality-oriented specification compliance can be enhanced by including a specification requirement that a vendor provide appropriate imagery at the various phases of the system life cycle. The nature and content of the imagery appropriate for each stage of the process depends on the nature of the test, the economics of collection, and the availability of techniques to extract the desired information from the data. At the earliest lifecycle stages, Concept and Technology Development (CTD) and System Development and Demonstration (SDD), the test set could include simulated imagery to demonstrate the mathematical and engineering concepts being implemented thus allowing demonstration of compliance, in part, through simulation. For Initial Operational Test and Evaluation (IOT&E), imagery collected from precisely instrumented test ranges and targets of opportunity consisting of a priori or a posteriori ground-truthed cultural and natural features are of value to the analysis of product quality compliance. Regular monitoring of image quality is possible using operational imagery and automated metrics; more precise measurements can be performed with imagery of instrumented scenes, when available. A survey of image quality measurement techniques is presented along with a discussion of the challenges of managing an airborne SAR program with the scarce resources of time, money, and ground-truthed data. Recommendations are provided that should allow an improvement in the product quality specification and maintenance process with a minimal increase in resource demands on the customer, the vendor, the operational personnel, and the asset itself.

This study evaluated the readability, accessibility and quality of information pertaining to breast reconstruction post mastectomy on the Internet in the English language. Using the Google © search engine the keywords "Breast reconstruction post mastectomy" were searched for. We analyzed the top 75 sites. The Flesch Reading Ease Score and Gunning Fog Index were calculated to assess readability. Web site quality was assessed objectively using the University of Michigan Consumer Health Web site Evaluation Checklist. Accessibility was determined using an automated accessibility tool. In addition, the country of origin, type of organisation producing the site and presence of Health on the Net (HoN) Certification status was recorded. The Web sites were difficult to read and comprehend. The mean Flesch Reading Ease scores were 55.5. The mean Gunning Fog Index scores was 8.6. The mean Michigan score was 34.8 indicating weak quality of websites. Websites with HoN certification ranked higher in the search results (p = 0.007). Website quality was influenced by organisation type (p < 0.0001) with academic/healthcare, not for profit and government sites having higher Michigan scores. 20% of sites met the minimum accessibility criteria. Internet information on breast reconstruction post mastectomy and procedures is poorly written and we suggest that Webpages providing information must be made more readable and accessible. We suggest that health professionals should recommend Web sites that are easy to read and contain high-quality surgical information. Medical information on the Internet should be readable, accessible, reliable and of a consistent quality. Copyright © 2017 Elsevier Ltd. All rights reserved.
Design implications for task-specific search utilities for retrieval and re-engineering of code
NASA Astrophysics Data System (ADS)

The importance of information retrieval systems is unquestionable in the modern society and both individuals as well as enterprises recognise the benefits of being able to find information effectively. Current code-focused information retrieval systems such as Google Code Search, Codeplex or Koders produce results based on specific keywords. However, these systems do not take into account developers' context such as development language, technology framework, goal of the project, project complexity and developer's domain expertise. They also impose additional cognitive burden on users in switching between different interfaces and clicking through to find the relevant code. Hence, they are not used by software developers. In this paper, we discuss how software engineers interact with information and general-purpose information retrieval systems (e.g. Google, Yahoo!) and investigate to what extent domain-specific search and recommendation utilities can be developed in order to support their work-related activities. In order to investigate this, we conducted a user study and found that software engineers followed many identifiable and repeatable work tasks and behaviours. These behaviours can be used to develop implicit relevance feedback-based systems based on the observed retention actions. Moreover, we discuss the implications for the development of task-specific search and collaborative recommendation utilities embedded with the Google standard search engine and Microsoft IntelliSense for retrieval and re-engineering of code. Based on implicit relevance feedback, we have implemented a prototype of the proposed collaborative recommendation system, which was evaluated in a controlled environment simulating the real-world situation of professional software engineers. The evaluation has achieved promising initial results on the precision and recall performance of the system.

Many health care performance measures are either not based on high-quality clinical evidence or not tightly linked to patient-centered outcomes, limiting their usefulness in quality improvement. In this report we summarize the proceedings of an American Thoracic Society workshop convened to address this problem by reviewing current approaches to performance measure development and creating a framework for developing high-quality performance measures by basing them directly on recommendations from well-constructed clinical practice guidelines. Workshop participants concluded that ideally performance measures addressing care processes should be linked to clinical practice guidelines that explicitly rate the quality of evidence and the strength of recommendations, such as the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process. Under this framework, process-based performance measures would only be developed from strong recommendations based on high- or moderate-quality evidence. This approach would help ensure that clinical processes specified in performance measures are both of clear benefit to patients and supported by strong evidence. Although this approach may result in fewer performance measures, it would substantially increase the likelihood that quality-improvement programs based on these measures actually improve patient care.

Wilson, Timmy R.; Kichak, Robert A.; Ungar, Eugene K.; Cherney, Robert; Rickman, Steve L.
2009-01-01
The NESC consultation team participated in real-time troubleshooting of the Main Propulsion System (MPS) Engine Cutoff (ECO) sensor system failures during STS-114 launch countdown. The team assisted with External Tank (ET) thermal and ECO Point Sensor Box (PSB) circuit analyses, and made real-time inputs to the Space Shuttle Program (SSP) problem resolution teams. Several long-term recommendations resulted. One recommendation was to conduct cryogenic tests of the ECO sensors to validate, or disprove, the theory that variations in circuit impedance due to cryogenic effects on swaged connections within the sensor were the root cause of STS-114 failures.
Engineering H5N1 avian influenza viruses to study human adaptation
Morens, David M.; Subbarao, Kanta; Taubenberger, Jeffery K.
2013-01-01
Two studies of H5N1 avian influenza viruses that had been genetically engineered to render them transmissible between ferrets have proved highly controversial. Divergent opinions exist about the importance of these studies of influenza transmission and about potential ‘dual use’ research implications. No consensus has developed yet about how to balance these concerns. After not recommending immediate full publication of earlier, less complete versions of the studies, the United States National Science Advisory Board for Biosecurity subsequently recommended full publication of more complete manuscripts; however, controversy about this and similar research remains.

1985-01-01
Various main propulsion system configurations of an advanced OTV are evaluated with respect to the probability of nonindependent failures, i.e., engine failures that disable the entire main propulsion system. Analysis of the life-cycle cost (LCC) indicates that LCC is sensitive to the main propulsion system reliability, vehicle dry weight, and propellant cost; it is relatively insensitive to the number of missions/overhaul, failures per mission, and EVA and IVA cost. In conclusion, two or three engines are recommended in view of their highest reliability, minimum life-cycle cost, and fail operational/fail safe capability.

Together with an expert committee a structured approach to determining quality indicators for National Disease Management Guidelines has been developed. The key steps of this approach include: introducing guideline authors to the methodology at an early stage of the process of guideline development, pre-selecting recommendations of the guideline which are potentially measurable by means of quality indicators, assessing the potentially measurable quality indicators in written form using five criteria (including their importance for the health care system and clarity of definitions) and approving them in a formal consensus process. For lack of a database these quality indicators must be regarded as preliminary. For the National Disease Management Guideline "Chronic Heart Failure" nine rate-based indicators have been chosen. The indicators correspond to important strong recommendations (grade of recommendation: A) from the fields of diagnosis (two), general therapeutic strategy (two), specific treatment (three), clinical monitoring (one) and co-ordination of care (one). In a second step, the quality indicators have to be validated within a pilot project. The determination and assessment of the potential quality indicators have revealed room for improvement of guideline development. In particular, there is a need for more health care data and for specification of recommendations.
A Flexible Electronic Commerce Recommendation System
NASA Astrophysics Data System (ADS)
Gong, Songjie
Recommendation systems have become very popular in E-commerce websites. Many of the largest commerce websites are already using recommender technologies to help their customers find products to purchase. An electronic commerce recommendation system learns from a customer and recommends products that the customer will find most valuable from among the available products. But most recommendation methods are hard-wired into the system and they support only fixed recommendations. This paper presented a framework of flexible electronic commerce recommendation system. The framework is composed by user model interface, recommendation engine, recommendation strategy model, recommendation technology group, user interest model and database interface. In the recommender strategy model, the method can be collaborative filtering, content-based filtering, mining associate rules method, knowledge-based filtering method or the mixed method. The system mapped the implementation and demand through strategy model, and the whole system would be design as standard parts to adapt to the change of the recommendation strategy.

At NewYork-Presbyterian Hospital, we are committed to the delivery of high quality care. We have implemented a strategic planning process to determine the information technology initiatives that will best help us improve quality. The process began with the creation of a Clinical Quality and IT Committee. The Committee identified 2 high priority goals that would enable demonstrably high quality care: 1) excellence at data warehousing, and 2) optimal use of automated clinical documentation to capture encounter-related quality and safety data. For each high priority goal, a working group was created to develop specific recommendations. The Data Warehousing subgroup has recommended the implementation of an architecture management process and an improved ability for users to get access to aggregate data. The Structured Documentation subgroup is establishing recommendations for a documentation template creation process. The strategic planning process at times is slow, but assures that the organization is focusing on the information technology activities most likely to lead to improved quality.

Preparing for an epidemic: cancer care in an aging population.
Shih, Ya-Chen Tina; Hurria, Arti
2014-01-01
The Institute of Medicine's (IOM) Committee on Improving the Quality of Cancer Care: Addressing the Challenges of an Aging Population was charged with evaluating and proposing recommendations on how to improve the quality of cancer care, with a specific focus on the aging population. Based on their findings, the IOM committee recently released a report highlighting their 10 recommendations for improving the quality of cancer care. Based on those recommendations, this article highlights ways to improve evidence-based care and addresses rising costs in health care for older adults with cancer. The IOM highlighted three recommendations to address the current research gaps in providing evidence-based care in older adults with cancer, which included (1) studying populations which match the age and health-risk profile of the population with the disease, (2) legislative incentives for companies to include patients that are older or with multiple morbidities in new cancer drug trials, and (3) expansion of research that contributes to the depth and breadth of data available for assessing interventions. The recommendations also highlighted the need to maintain affordable and accessible care for older adults with cancer, with an emphasis on finding creative solutions within both the care delivery system and payment models in order to balance costs while preserving quality of care. The implementation of the IOM's recommendations will be a key step in moving closer to the goal of providing accessible, affordable, evidence-based, high-quality care to all patients with cancer.

Heldenbrand, R. W.; Merrill, G. L.; Burnett, G. A.
1975-01-01
Small turbofan engine design concepts were applied to military trainer airplanes to establish the potential for commonality between civil and military engines. Several trainer configurations were defined and studied. A ""best'' engine was defined for the trainer mission, and sensitivity analyses were performed to determine the effects on airplane size and efficiency of wing loading, power loading, configuration, aerodynamic quality, and engine quality. It is concluded that a small civil aircraft is applicable to military trainer airplanes. Aircraft designed with these engines are smaller, less costly, and more efficient than existing trainer aircraft.

Brown, Philip W.
1987-01-01
Brief flight evaluations of two different, light, composite constructed, canard and winglet configured airplanes were performed to assess their handling qualities; one airplane was a single engine, pusher design and the other a twin engine, push-pull configuration. An emphasis was placed on the slow speed/high angle of attack region for both airplanes and on the engine-out regime for the twin. Mission suitability assessment included cockpit and control layout, ground and airborne handling qualities, and turbulence response. Very limited performance data was taken. Stall/spin tests and the effects of laminar flow loss on performance and handling qualities were assessed on an extended range, single engine pusher design.

Since its inception in March 2014, the NASA Data Quality Working Group (DQWG) has procured a set of 12 high level recommendations which had been sifted from and aggregated from a prioritized subset of nearly 100 unique recommendations spanning four unique data quality management phases and distributed between two actionable categories. The four data quality management phases as identified by the DQWG are: 1. Capturing (i.e., deriving, collecting and organizing the information), 2. Describing (i.e., documenting and procuring the information for public consumption), 3. Facilitating Discovery (i.e., publishing and providing access to the information), and 4. Enabling Use (i.e., enhancing the utility of the information). Mapping each of our recommendations to one or more of the above management phases is intended to enable improved assessment of cost, feasibility, and relevancy to the entities responsible for implementing such recommendations. The DQWG further defined two distinct actionable categories: 1) Data Systems and 2) Science. The purpose of these actionable categories is to define specifically who is responsible for the implementation and adherence toward these recommendations; we refer to the responsible entities as the "actionees". Here we will summarize each of the high level recommendations along with their corresponding management phases and actionees. We will present what has recently been identified as our set of "low-hanging fruit" recommendations, which are intended for near-term implementation. Finally, we will present the status and motivation for continuing and future planned activities, which include but are not limited to: engaging inter-agency and international communities, more direct feedback from Earth observation missions, and mapping of "low-hanging fruit" recommendations to existing solutions.
Practical quality control tools for curves and surfaces

Clinical practice guidelines (CPGs) have been developed to summarize evidence about the management of rheumatoid arthritis (RA) and facilitate the uptake of evidence-based knowledge by consumers, health professionals, health administrators and policy makers. The objectives of this review was to assess the quality of CPGS on non-pharmacological management of RA with a standardized and validated instrument--the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool and summarize the key recommendations from these CPGs. Scientific literature databases from 2001 to 2013 were systematically searched and a total of 13 CPGs for RA was identified. Only a minority of AGREE II domains were effectively addressed by the CPGS. Scope and purpose was effectively addressed in 10 out of 13 CPGs, stakeholder involvement in 11 CPGs, rigor of development in 6 CPGs, clarity/presentation in 9 CPGs, editorial independence in 1 CPGs, and applicability in none of the CPGs. The overall quality of the included CPGs according to the 7-point AGREE II scoring system was 4.8 ± 1.04. Patient education/self-management, aerobic, dynamic and stretching exercises were the commonly recommended for the non-pharmacological management of RA by the high-quality CPGs. The general clinical management recommendations tended to be similar among high-quality CPGs. Non-pharmacological management interventions were superficially addressed in more than half of the selected CPGs. CPGs creators should use the AGREE II criteria when developing guidelines. Innovative and effective methods of CPGs implementation to users are needed to ultimately enhance the quality of life of arthritic individuals. In addition, it was difficult to establish between strongly recommended, recommended and weakly recommended, as there is no consensus between the strength of the recommendations between the appraised CPGs.
Feasibility of CO/sub 2/ monitoring to assess air quality in mines using diesel equipment
DOE Office of Scientific and Technical Information (OSTI.GOV)
Daniel, J.H. Jr.
1987-01-01
The methodology includes: (1) establishing pollutant to CO/sub 2/ ratios for in-service equipment, (2) estimating pollutant concentrations from the ratios and in-mine CO/sub 2/ measurements, and (3) using an air quality index to combine the pollutants into a single number, which indicates the health hazard associated with the pollutants. For the methodology to be valid, the pollutant to CO/sub 2/ ratios must remain constant if engine operating conditions do not significantly change. However, due to the complex dynamics of the fuel injection system, the fuel-air combustion process, and the engine speed-load governing system, the pollutant to CO/sub 2/ ratios maymore » vary during repetitive, but transient engine speed-and-load operation. These transient effects were investigated. In addition, the influence of changing engine conditions due to engine maladjustment, and a practical means to evaluate engine condition were investigated to advance the methodology. The laboratory investigation determined that CO/sub 2/ is an effective indicator of engine exhaust pollutants. It was shown that the exhaust concentrations of carbon monoxide, carbon dioxide, oxides of nitrogen, hydrocarbons, and particulate matter do not significantly vary among repetitive, but transient engine speed-and-load duty cycles typical of in-service equipment. Based on an air quality index and threshold limit values, particulate matter exhibited the greatest adverse effect on air quality. Particulate mass was separated into volatile (organic soluble fraction) and nonvolatile (insoluble carbon fraction) components. Due to particulate concentrations, the engine operating conditions of overfueling and advanced injector timing had greater adverse effects on air quality than the conditions of retarded injector timing, intake air restriction, and Federal certification specifications.« less

Methodology For Reduction Of Sampling On The Visual Inspection Of Developed And Etched Wafers
NASA Astrophysics Data System (ADS)
van de Ven, Jamie S.; Khorasani, Fred
1989-07-01
There is a lot of inspection in the manufacturing of semiconductor devices. Generally, the more important a manufacturing step, the higher is the level of inspection. In some cases 100% of the wafers are inspected after certain steps. Inspection is a non-value added and expensive activity. It requires an army of "inspectors," often times expensive equipment and becomes a "bottle neck" when the level of inspection is high. Although inspection helps identify quality problems, it hurts productivity. The new management, quality and productivity philosophies recommend against over inspection. [Point #3 in Dr. Deming's 14 Points for Management (1)] 100% inspection is quite unnecessary . Often the nature of a process allows us to reduce inspection drastically and still maintain a high level of confidence in quality. In section 2, we discuss such situations and show that some elementary probability theory allows us to determine sample sizes and measure the chances of catching a bad "lot" and accepting a good lot. In section 3, we provide an example and application of the theory, and make a few comments on money and time saved because of this work. Finally, in section 4, we draw some conclusions about the new quality and productivity philosophies and how applied statisticians and engineers should study every situation individually and avoid blindly using methods and tables given in books.

Requirements engineering is at the heart and foundation of software engineering process. Poor quality requirements inevitably lead to poor quality software solutions. Also, poor requirement modeling is tantamount to designing a poor quality product. So, quality assured requirements development collaborates fine with usable products in giving the software product the needed quality it demands. In the light of the foregoing, the requirements for an e-Ebola Awareness Portal were modeled with a good attention given to these software engineering concerns. The requirements for the e-Health Awareness Portal are modeled as a contribution to the fight against Ebola and helps in the fulfillment of the United Nation's Millennium Development Goal No. 6. In this study requirements were modeled using UML 2.0 modeling technique.

A description of a recommended air quality monitoring network to characterize the impact on ambient air quality in the Kennedy Space Center (KSC) (area) of space shuttle launch operations is given. Analysis of ground cloud processes and prevalent meteorological conditions indicates that transient HCl depositions can be a cause for concern. The system designed to monitor HCl employs an extensive network of inexpensive detectors combined with a central analysis device. An acid rain network is also recommended. A quantitative measure of projected minimal long-term impact involves the limited monitoring of NOx and particulates. All recommended monitoring is confined ti KSC property.

Research focusing on management of foot health has become more evident over the past decade, especially related to chronic conditions such as diabetes. The level of methodological rigour across this body of work however is varied and outputs do not appear to have been developed or translated into clinical practice. The aim of this systematic review was to assess the latest guidelines, standards of care and current recommendations relative to people with chronic conditions to ascertain the level of supporting evidence concerning the management of foot health. A systematic search of electronic databases (Medline, Embase, Cinahl, Web of Science, SCOPUS and The Cochrane Library) for literature on recommendations for foot health management for people with chronic conditions was performed between 2000 and 2016 using predefined criteria. Data from the included publications was synthesised via template analysis, employing a thematic organisation and structure. The methodological quality of all included publications was appraised using the Appraisal for Research and Evaluation (AGREE II) instrument. A more in-depth analysis was carried out that specifically considered the levels of evidence that underpinned the strength of their recommendations concerning management of foot health. The data collected revealed 166 publications in which the majority (102) were guidelines, standards of care or recommendations related to the treatment and management of diabetes. We noted a trend towards a systematic year on year increase in guidelines standards of care or recommendations related to the treatment and management of long term conditions other than diabetes over the past decade. The most common recommendation is for preventive care or assessments (e.g. vascular tests), followed by clinical interventions such as foot orthoses, foot ulcer care and foot health education. Methodological quality was spread across the range of AGREE II scores with 62 publications falling into the category of high quality (scores 6-7). The number of publications providing a recommendation in the context of a narrative but without an indication of the strength or quality of the underlying evidence was high (79 out of 166). It is clear that evidence needs to be accelerated and in place to support the future of the Podiatry workforce. Whilst high level evidence for podiatry is currently low in quantity, the methodological quality is growing. Where levels of evidence have been given in in high quality guidelines, standards of care or recommendations, they also tend to be strong-moderate quality such that further strategically prioritised research, if performed, is likely to have an important impact in the field.

Recommender system offers a powerful tool to make information overload problem well solved and thus gains wide concerns of scholars and engineers. A key challenge is how to make recommendations more accurate and personalized. We notice that community structures widely exist in many real networks, which could significantly affect the recommendation results. By incorporating the information of detected communities in the recommendation algorithms, an improved recommendation approach for the networks with communities is proposed. The approach is examined in both artificial and real networks, the results show that the improvement on accuracy and diversity can be 20% and 7%, respectively. This reveals that it is beneficial to classify the nodes based on the inherent properties in recommender systems.

The European Water framework directive (WFD) is probably the most important environmental management directive that has been enacted over the last decade in the European Union. The directive aims at achieving an overall good ecological status in all European water bodies. In this article, we discuss the implementation steps of the WFD and their implications for environmental engineering practice while focusing on rivers as the main receiving waters. Arising challenges for engineers and scientists are seen in the quantitative assessment of water quality, where standardized systems are needed to estimate the biological status. This is equally of concern in engineering planning, where the prediction of ecological impacts is required. Studies dealing with both classification and prediction of the ecological water quality are reviewed. Further, the combined emission-water quality approach is discussed. Common understanding of this combined approach is to apply the most stringent of either water quality or emission standard to a certain case. In contrast, for example, the Austrian water act enables the application of only the water quality based approach--at least on a temporary basis.

Inherited neurometabolic disorders (iNMDs) represent a group of almost seven hundred rare diseases whose common manifestations are clinical neurologic or cognitive symptoms that can appear at any time, in the first months/years of age or even later in adulthood. Early diagnosis and timely treatments are often pivotal for the favorable course of the disease. Thus, the elaboration of new evidence-based recommendations for iNMD diagnosis and management is increasingly requested by health care professionals and patients, even though the methodological quality of existing guidelines is largely unclear. InNerMeD-I-Network is the first European network on iNMDs that was created with the aim of sharing and increasing validated information about diagnosis and management of neurometabolic disorders. One of the goals of the project was to determine the number and the methodological quality of existing guidelines and recommendations for iNMDs. We performed a systematic search on PubMed, the National Guideline Clearinghouse (NGC), the Guidelines International Network (G-I-N), the Scottish Intercollegiate Guideline Network (SIGN) and the National Institute for Health and Care Excellence (NICE) to identify all the published guidelines and recommendations for iNMDs from January 2000 to June 2015. The methodological quality of the selected documents was determined using the AGREE II instrument, an appraisal tool composed of 6 domains covering 23 key items. A total of 55 records met the inclusion criteria, 11 % were about groups of disorders, whereas the majority encompassed only one disorder. Lysosomal disorders, and in particular Fabry, Gaucher disease and mucopolysaccharidoses where the most studied. The overall methodological quality of the recommendation was acceptable and increased over time, with 25 % of the identified guidelines strongly recommended by the appraisers, 64 % recommended, and 11 % not recommended. However, heterogeneity in the obtained scores for each domain was observed among documents covering different groups of disorders and some domains like 'stakeholder involvement' and 'applicability' were generally scarcely addressed. Greater efforts should be devoted to improve the methodological quality of guidelines and recommendations for iNMDs and AGREE II instrument seems advisable for new guideline development. The elaboration of new guidelines encompassing still uncovered disorders is badly needed.

Vertebral compression fractures (VCFs) are the most common type of osteoporotic fracture comprising approximately 1.4 million cases worldwide. Clinical practice guidelines can be powerful tools for promoting evidence-based practice as they integrate research findings to support decision making. However, currently available clinical guidelines and recommendations, established by different medical societies, are sometimes contradictory. The aim of this study was to appraise the recommendations and the methodological quality of international clinical guidelines for the management of VCFs. This is a systematic review of clinical guidelines for the management of VCF. Guidelines were selected by searching MEDLINE and PubMed, PEDro, CINAHL, and EMBASE electronic databases between 2010 and 2016. We also searched clinical practice guideline databases, including the National Guideline Clearinghouse and the Canadian Medical Association InfoBase. The methodological quality of the guidelines was assessed by two authors independently using the Appraisal of Guidelines, Research and Evaluation (AGREE) II Instrument. We also classified the strength of each recommendation as either strong (ie, based on high-quality studies with consistent findings for recommending for or against the intervention), weak (ie, based on a lack of compelling evidence resulting in uncertainty for benefit or potential harm), or expert consensus (ie, based on expert opinion of the working group rather than on scientific evidence). Guideline recommendations were grouped into diagnostic, conservative care, interventional care, and osteoporosis treatment and prevention of future fractures. Our study was prospectively registered on PROSPERO. Four guidelines from three countries, published in the period 2010-2013, were included. In general, the quality was not satisfactory (50% or less of the maximum possible score). The domains scoring 50% or less of the maximum possible score were rigor of development, clarity of presentation, and applicability. The use of plain radiography or dual-energy X-ray absorptiometry for diagnosis was recommended in two of the four guidelines. Vertebroplasty or kyphoplasty was recommended in three of the four guidelines. The recommendation for bed rest, trunk orthoses, electrical stimulation, and supervised or unsupervised exercise was inconsistent across the included guidelines. The comparison of clinical guidelines for the management of VCF showed that diagnostic and therapeutic recommendations were generally inconsistent. The evidence available to guideline developers was limited in quantity and quality. Greater efforts are needed to improve the quality of the majority of guidelines. Copyright © 2017 Elsevier Inc.

Research Perspectives: The 2013 AAOS/ORS Research Symposium on Bone Quality and Fracture Prevention
Donnelly, Eve; Lane, Joseph M.; Boskey, Adele L.
2016-01-01
Bone fracture resistance is determined by the amount of bone present (“bone quantity”) and by a number of other geometric and material factors grouped under the term “bone quality.” In May 2013, a workshop was convened among a group of clinicians and basic science investigators to review the current state of the art in Bone Quality and Fracture Prevention and to make recommendations for future directions for research. The AAOS/ORS/OREF workshop was attended by 64 participants, including two representatives of the National Institutes of Arthritis and Musculoskeletal and Skin Diseases and 13 new investigators whose posters stimulated additional interest. A key outcome of the workshop was a set of recommendations regarding clinically relevant aspects of both bone quality and quantity that clinicians can use to inform decisions about patient care and management. The common theme of these recommendations was the need for more education of clinicians in areas of bone quality and for basic science studies to address specific topics of pathophysiology, diagnosis, prevention, and treatment of altered bone quality. In this report, the organizers with the assistance of the speakers and other attendees highlight the major findings of the meeting that justify the recommendations and needs for this field.

Objective Patients commonly use the Internet to obtain their health-related information. The purpose of this study was to investigate the quality, accuracy, and readability of online patient resources for the management of articular cartilage defects. Design Three search terms ("cartilage defect," "cartilage damage," "cartilage injury") were entered into 3 Internet search engines (Google, Bing, Yahoo). The first 25 websites from each search were collected and reviewed. The quality and accuracy of online information were independently evaluated by 3 reviewers using predetermined scoring criteria. The readability was evaluated using the Flesch-Kincaid (FK) grade score. Results Fifty-three unique websites were evaluated. Quality ratings were significantly higher in websites with a FK score >11 compared to those with a score of ≤11 ( P = 0.021). Only 10 websites (19%) differentiated between focal cartilage defects and diffuse osteoarthritis. Of these, 7 (70%) were elicited using the search term "cartilage defect" ( P = 0.038). The average accuracy of the websites was high (11.7 out of maximum 12), and the average FK grade level (13.4) was several grades higher than the recommended level for readable patient education material (eighth grade level). Conclusions The quality and readability of online patient resources for articular cartilage defects favor those with a higher level of education. Additionally, the majority of these websites do not distinguish between focal chondral defects and diffuse osteoarthritis, which can fail to provide appropriate patient education and guidance for available treatment. Clinicians should help guide patients toward high-quality, accurate, and readable online patient education material.

Background Most travellers’ diarrhea (TD) infections occur during travel to low- and middle-income countries. Type of travel, duration of stay, age of traveller and presence of certain medical conditions are important factors to consider for risk of TD. The Committee to Advise on Tropical Medicine and Travel (CATMAT) assembled a TD working group to develop recommendations on prevention and treatment of TD in travellers. This document is a summary of the Statement on Travellers’ Diarrhea. Methods Following a systematic review of the literature, recommendations on the prevention and treatment of TD were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to evaluate data quality, benefits and harms of the intervention, and values and preferences of the traveller. Other recommendations were based on a review of the literature and expert opinion. Recommendations Using the GRADE methodology, CATMAT concluded that oral cholera vaccine should not be routinely recommended to prevent TD in Canadian travellers. This recommendation was based on moderate quality data that showed this vaccine was not effective in preventing TD in travellers compared to placebo. Bismuth subsalicylate (BSS), fluoroquinolones or rifaximin are options for the prevention of TD based on high-quality data for BSS and fluoroquinolones and moderate evidence for rifaximin. For the treatment of TD, loperamide (alone or in combination with antibiotics), fluoroquinolones, azithromycin and rifaximin are all options, with varying degrees of data quality. Based on available evidence and expert opinion, CATMAT recommends handwashing or the use of hand sanitizer, as well as prudent choice and preparation of food and beverages as best practices for preventing diarrhea while travelling. At this time, a recommendation cannot be made for either the use of probiotics and prebiotics to prevent TD or the use of BSS to treat TD due to insufficient available evidence. Conclusion With the exception of BSS for prevention of TD (strong recommendation for use), CATMAT conditionally recommends the use of each of the other GRADE-evaluated preventive and therapeutic products assessed in this Statement. These CATMAT recommendations should be considered as options in the prevention and treatment of TD based on the particular situation of the traveller. PMID:29769922
Formalization of the engineering science discipline - knowledge engineering
NASA Astrophysics Data System (ADS)
Peng, Xiao
Knowledge is the most precious ingredient facilitating aerospace engineering research and product development activities. Currently, the most common knowledge retention methods are paper-based documents, such as reports, books and journals. However, those media have innate weaknesses. For example, four generations of flying wing aircraft (Horten, Northrop XB-35/YB-49, Boeing BWB and many others) were mostly developed in isolation. The subsequent engineers were not aware of the previous developments, because these projects were documented such which prevented the next generation of engineers to benefit from the previous lessons learned. In this manner, inefficient knowledge retention methods have become a primary obstacle for knowledge transfer from the experienced to the next generation of engineers. In addition, the quality of knowledge itself is a vital criterion; thus, an accurate measure of the quality of 'knowledge' is required. Although qualitative knowledge evaluation criteria have been researched in other disciplines, such as the AAA criterion by Ernest Sosa stemming from the field of philosophy, a quantitative knowledge evaluation criterion needs to be developed which is capable to numerically determine the qualities of knowledge for aerospace engineering research and product development activities. To provide engineers with a high-quality knowledge management tool, the engineering science discipline Knowledge Engineering has been formalized to systematically address knowledge retention issues. This research undertaking formalizes Knowledge Engineering as follows: 1. Categorize knowledge according to its formats and representations for the first time, which serves as the foundation for the subsequent knowledge management function development. 2. Develop an efficiency evaluation criterion for knowledge management by analyzing the characteristics of both knowledge and the parties involved in the knowledge management processes. 3. Propose and develop an innovative Knowledge-Based System (KBS), AVD KBS, forming a systematic approach facilitating knowledge management. 4. Demonstrate the efficiency advantages of AVDKBS over traditional knowledge management methods via selected design case studies. This research formalizes, for the first time, Knowledge Engineering as a distinct discipline by delivering a robust and high-quality knowledge management and process tool, AVDKBS. Formalizing knowledge proves to significantly impact the effectiveness of aerospace knowledge retention and utilization.
A Stirling engine for use with lower quality fuels
NASA Astrophysics Data System (ADS)
Paul, Christopher J.
There is increasing interest in using renewable fuels from biomass or alternative fuels such as municipal waste to reduce the need for fossil based fuels. Due to the lower heating values and higher levels of impurities, small scale electricity generation is more problematic. Currently, there are not many technologically mature options for small scale electricity generation using lower quality fuels. Even though there are few manufacturers of Stirling engines, the history of their development for two centuries offers significant guidance in developing a viable small scale generator set using lower quality fuels. The history, development, and modeling of Stirling engines were reviewed to identify possible model and engine configurations. A Stirling engine model based on the finite volume, ideal adiabatic model was developed. Flow dissipation losses are shown to need correcting as they increase significantly at low mean engine pressure and high engine speed. The complete engine including external components was developed. A simple yet effective method of evaluating the external heat transfer to the Stirling engine was created that can be used with any second order Stirling engine model. A derivative of the General Motors Ground Power Unit 3 was designed. By significantly increasing heater, cooler and regenerator size at the expense of increased dead volume, and adding a combustion gas recirculation, a generator set with good efficiency was designed.

To evaluate the impact of continued education provided by an external quality control laboratory on the indicators of internal quality control of cytopathology exams. The internal quality assurance indicators for cytopathology exams from 12 laboratories monitored by the External Quality Control Laboratory were evaluated. Overall, 185,194 exams were included, 98,133 of which referred to the period preceding implementation of a continued education program, while 87,061 referred to the period following this intervention. Data were obtained from the Cervical Cancer Database of the Brazilian National Health Service. Following implementation of the continued education program, the positivity index (PI) remained within recommended limits in four laboratories. In another four laboratories, the PI progressed from below the limits to within the recommended standards. In one laboratory, the PI remained low, in two laboratories, it remained very low, and in one, it increased from very low to low. The percentage of exams compatible with a high-grade squamous intraepithelial lesion (HSIL) remained within the recommended limits in five laboratories, while in three laboratories it progressed from below the recommended levels to >0.4% of the total number of satisfactory exams, and in four laboratories it remained below the standard limit. Both the percentage of atypical squamous cells of undetermined significance (ASC-US) in relation to abnormal exams, and the ratio between ASC-US and intraepithelial lesions remained within recommended levels in all the laboratories investigated. An improvement was found in the indicators represented by the positivity index and the percentage of exams compatible with a high-grade squamous intraepithelial lesion, showing that the role played by the external quality control laboratory in providing continued education contributed towards improving laboratory staff skills in detecting cervical cancer precursor lesions.

Indoor air pollution mitigation measures are highly important due to the associated health impacts, especially on children, a risk group that spends significant time indoors. Thus, the main goal of the work here reported was the evaluation of mitigation measures implemented in nursery and primary schools to improve air quality. Continuous measurements of CO₂, CO, NO₂, O₃, CH₂O, total volatile organic compounds (VOC), PM₁, PM 2.5 , PM 10 , Total Suspended Particles (TSP) and radon, as well as temperature and relative humidity were performed in two campaigns, before and after the implementation of low-cost mitigation measures. Evaluation of those mitigation measures was performed through the comparison of the concentrations measured in both campaigns. Exceedances to the values set by the national legislation and World Health Organization (WHO) were found for PM 2.5 , PM 10 , CO₂ and CH₂O during both indoor air quality campaigns. Temperature and relative humidity values were also above the ranges recommended by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). In general, pollutant concentrations measured after the implementation of low-cost mitigation measures were significantly lower, mainly for CO₂. However, mitigation measures were not always sufficient to decrease the pollutants' concentrations till values considered safe to protect human health.

Research activities in Saudi Arabia are promoted at the governmental and institutional levels. However, the output and quality of research conducted in the field of neurology has not yet been measured quantitatively. This study therefore aimed to analyse neurology-related publications from Saudi Arabia. This study was conducted in January 2016. A systematic search using the PubMed ® search engine (National Library of Medicine, Bethesda, Maryland, USA) was conducted to identify all neurology-related articles published from Saudi Arabia between January 1996 and December 2015. A total of 1,292 neurology-related publications were identified. Neurology research increased linearly with time, with most publications originating from Riyadh (67%) and the university sector (≈47%). However, most neurology-related articles were published in journals which had an impact factor of <1 (55%). Neurology research in Saudi Arabia has increased substantially over the last 20 years. However, as most articles were published in low-impact journals, the quality of research remains inadequate and should be improved. It is important that an official research culture be established in both governmental and private universities as well as colleges and health institutions in Saudi Arabia. The formation of clinical academic departments staffed by research experts is recommended to ensure the quality of neurology research output.

This systematic review was conducted to identify effective occupational health and safety interventions for small businesses. The review focused on peer-reviewed intervention studies conducted in small businesses with 100 or fewer employees, that were published in English and several other languages, and that were not limited by publication date. Multidisciplinary members of the review team identified relevant articles and assessed their quality. Studies assessed as medium or high quality had data extracted, which was then synthesized. Five studies were deemed of medium or high quality, and proceeded to data extraction and evidence synthesis. The types of interventions identified: a combination of training and safety audits; and a combination of engineering, training, safety audits, and a motivational component, showed a limited amount of evidence in improving safety outcomes. Overall, this evidence synthesis found a moderate level of evidence for intervention effectiveness, and found no evidence that any intervention had adverse effects. Even though there were few studies that adequately evaluated small business intervention, several studies demonstrate that well-designed evaluations are possible with small businesses. While stronger levels of evidence are required to make recommendations, these interventions noted above were associated with positive changes in safety-related attitudes and beliefs and workplace parties should be aware of them.

Aspartate aminotransferase (AST; E.C. 2.6.1.1), a vitamin B6-dependent enzyme, preferentially promotes the mutual transformation of aspartate and α-ketoglutarate to oxaloacetate and glutamate. It plays a key role in amino acid metabolism and has been widely recommended as a biomarker of liver and heart damage. Our study aimed to evaluate the extensive preparation of AST and its application in quality control in clinical laboratories. We describe a scheme to express and purify the 6His-AST fusion protein. An optimized sequence coding AST was synthesized and transformed into Escherichia coli BL21 (DE3) strain for protein expression. Ideally, the fusion protein has a volumetric productivity achieving 900 mg/l cultures. After affinity chromatography, the enzyme activity of purified AST reached 150,000 U/L. Commutability assessment between the engineered AST and standard AST from Roche suggested that the engineered AST was the better candidate for the reference material. Moreover, the AST showed high stability during long-term storage at -20ºC. In conclusion, the highly soluble 6His-tagged AST can become a convenient tool for supplying a much better and cheaper standard or reference material for the clinical laboratory.

Word-of-mouth (WOM) refers to communication among consumers, which greatly influences the marketing strategies of dental clinics. This study aimed to explore factors that affect use of WOM by dental patients and to analyse their pathways. The participants were 520 outpatients from four private dental clinics. Data were obtained from a survey using self-reported questionnaires, which included questions regarding seven latent variables: five exogenous variables, including medical service quality (physical environment, customer service, patient relationship quality) and individual characteristic variables (opinion leader tendency, social hub tendency); and two endogenous variables (intention to recommend, WOM experience). Statistical analysis was performed using structural equation modelling. Significant associations were found in the pathways between relationship quality and intention to recommend, intention to recommend and WOM, and opinion leader tendency and WOM (P < 0.001). Higher patient relationship quality and higher intention to recommend were related to positive WOM, as was higher opinion leader tendency. Improving patient relationship quality can promote positive WOM for dental clinics. Strategies are needed to promote a positive perception of dental clinics by effectively responding to the views of patients with strong opinion leader tendencies. © 2018 FDI World Dental Federation.

The recently completed study for the Advanced Technology Large-Aperture Telescope (ATLAST) was the culmination of three years of work that built upon earlier engineering designs, science objectives, and sustained recommendations for technology investments. Since the mid-1980s, multiple teams of astronomers, technologists, and engineers have developed concepts for a large-aperture UV/optical/IR space observatory to follow the Hubble Space Telescope (HST). Especially over the past decade, technology advances and exciting scientific results has led to growing support for development in the 2020s of a large UVOIR space observatory. Here we summarize the history of major mission designs, scientific goals, key technology recommendations, community workshops and conferences, and recommendations to NASA for a major UV/optical/IR observatory to follow HST. We conclude with a capsule summary of the ATLAST reference design developed over the past three years.

The exponential increase in health-related online platforms has made the Internet one of the main sources of health information globally. The quality of health contents disseminated on the Internet has been a central focus for many researchers. To date, however, few comparative content analyses of pro- and anti-vaccination websites have been conducted, and none of them compared the quality of information. The main objective of this study was therefore to bring new evidence on this aspect by comparing the quality of pro- and anti-vaccination online sources. Based on past literature and health information quality evaluation initiatives, a 40-categories assessment tool (Online Vaccination Information Quality Codebook) was developed and used to code a sample of 1093 webpages retrieved via Google and two filtered versions of the same search engine. The categories investigated were grouped into four main quality dimensions: web-related design quality criteria (10 categories), health-specific design quality criteria (3 categories), health related content attributes (12 categories) and vaccination-specific content attributes (15 categories). Data analysis comprised frequency counts, cross tabulations, Pearson's chi-square, and other inferential indicators. The final sample included 514 webpages in favor of vaccination, 471 against, and 108 neutral. Generally, webpages holding a favorable view toward vaccination presented more quality indicators compared to both neutral and anti-vaccination pages. However, some notable exceptions to this rule were observed. In particular, no differences were found between pro- and anti-vaccination webpages as regards vaccination-specific content attributes. Our analyses showed that the overall quality of pro-vaccination webpages is superior to anti-vaccination online sources. The developed coding scheme was proven to be a helpful and reliable tool to judge the quality of vaccination-related webpages. Based on the results, we advance recommendations for online health information providers as well as directions for future research in this field.

Some experiences of NASA configuration management in providing concurrent engineering support to the Space Station Freedom program for the achievement of life cycle benefits and total quality are discussed. Three change decision experiences involving tracing requirements and automated information systems of the electrical power system are described. The potential benefits of concurrent engineering and total quality management include improved operational effectiveness, reduced logistics and support requirements, prevention of schedule slippages, and life cycle cost savings. It is shown how configuration management can influence the benefits attained through disciplined approaches and innovations that compel consideration of all the technical elements of engineering and quality factors that apply to the program development, transition to operations and in operations. Configuration management experiences involving the Space Station program's tiered management structure, the work package contractors, international partners, and the participating NASA centers are discussed.

We conducted a systematic review of clinical guidelines (CGs) to examine the methodological approaches of quality indicator derivation in CGs, the frequency of quality indicators to check CG recommendations in routine care, and clinimetric properties of quality indicators. We analyzed the publicly available CG databases of the Association of the Scientific Medical Societies in Germany (AWMF) and National Institute for Health and Care Excellence (NICE). Data on the methodology of subsequent quality indicator derivation, the content and definition of recommended quality indicators, and clinimetric properties of measurement instruments were extracted. In Germany, no explicit methodological guidance exists, but 3 different approaches are used. For NICE, a general approach is used for the derivation of quality indicators out of quality standards. Quality indicators were defined in 34 out of 87 CGs (39%) in Germany and for 58 out of 133 (43%) NICE CGs. Statements regarding measurement properties of instruments for quality indicator assessment were missing in German and NICE documents. Thirteen pairs of CGs (32%) have associated quality indicators. Thirty-four quality indicators refer to the same aspect of the quality of care, which corresponds to 27% of the German and 7% of NICE quality indicators. The development of a standardized and internationally accepted methodology for the derivation of quality indicators relevant to CGs is needed to measure and compare quality of care in health care systems.

An analysis was conducted to screen, evaluate, and select three engine exhaust emission reduction concepts from a group of 14 candidate alternatives. A comprehensive literature search was conducted to survey the emission reduction technology state-of-the-art and establish contact with firms working on intermittent combustion engine development and pollution reduction problems. Concept development, advantages, disadvantages, and expected emission reduction responses are stated. A set of cost effectiveness criteria was developed, appraised for relative importance, and traded off against each concept so that its merit could be determined. A decision model was used to aid the evaluators in managing the criteria, making consistent judgements, calculating merit scores, and ranking the concepts. An Improved Fuel Injection System, Improved Cooling Combustion Chamber, and a Variable Timing Ignition System were recommended to NASA for approval and further concept development. An alternate concept, Air Injection, was also recommended.

This paper implements a threaded scan engine for the O(n!) search space and measures its performance, aiming at providing a responsive tour recommendation and scheduling service. As a preliminary step of integrating POI ontology, mobile object database, and personalization profile for the development of new vehicular telematics services, this implementation can give a useful guideline to design a challenging and computation-intensive vehicular telematics service. The implemented engine allocates the subtree to the respective threads and makes them run concurrently exploiting the primitives provided by the operating system and the underlying multiprocessor architecture. It also makes it easy to add a variety of constraints, for example, the search tree is pruned if the cost of partial allocation already exceeds the current best. The performance measurement result shows that the service can run even in the low-power telematics device when the number of destinations does not exceed 15, with an appropriate constraint processing.

Background The Joint Asia Diabetes Evaluation (JADE) Program is a web-based program incorporating a comprehensive risk engine, care protocols, and clinical decision support to improve ambulatory diabetes care. Methods The JADE Program uses information technology to facilitate healthcare professionals to create a diabetes registry and to deliver an evidence-based care and education protocol tailored to patients' risk profiles. With written informed consent from participating patients and care providers, all data are anonymized and stored in a databank to establish an Asian Diabetes Database for research and publication purpose. Results The JADE electronic portal (e-portal: http://www.jade-adf.org) is implemented as a Java application using the Apache web server, the mySQL database and the Cocoon framework. The JADE e-portal comprises a risk engine which predicts 5-year probability of major clinical events based on parameters collected during an annual comprehensive assessment. Based on this risk stratification, the JADE e-portal recommends a care protocol tailored to these risk levels with decision support triggered by various risk factors. Apart from establishing a registry for quality assurance and data tracking, the JADE e-portal also displays trends of risk factor control at each visit to promote doctor-patient dialogues and to empower both parties to make informed decisions. Conclusions The JADE Program is a prototype using information technology to facilitate implementation of a comprehensive care model, as recommended by the International Diabetes Federation. It also enables health care teams to record, manage, track and analyze the clinical course and outcomes of people with diabetes. PMID:20465815

The US Nuclear Regulatory Commission (NRC) in September 1991, completed revisions to 14 sections of the Standard Review Plan (SRP) for the Review of a License Application for a Low-Level Radioactive Waste Disposal Facility. The major purposes of the SRP are to ensure the quality and uniformity of the NRC staff`s safety reviews, and to present a well-defined base from which to evaluate the acceptability of information and data provided in the Safety Analysis Report (SAR) portion of the license application. SRP 3.2, entitled, Design Considerations for Normal and Abnormal/Accident Conditions, was one of the sections that was revised bymore » the NRC staff. This revision was completed to provide additional regulatory guidance on the important considerations that need to be addressed for the proper design and construction of soil cover systems that are to be placed over the LLW. The cover system over the waste is acknowledged to be one of the most important engineered barriers for the long-term stable performance of the disposal facility. The guidance in revised SRP 3.2 summarizes the previous efforts and recommendations of the US Army Corps of Engineers (COE), and a peer review panel on the placement of soil cover systems. NRC published these efforts in NUREG/CR-5432. The discussions in this paper highlight selected recommendations on soil cover issues that the NRC staff considers important for ensuring the safe, long-term performance of the soil cover systems. The development phases to be discussed include: (1) cover design; (2) cover material selection; (3) laboratory and field testing; (4) field placement control and acceptance; and (5) penetrations through the constructed covers.« less
Quality Measures for the Care of Patients with Insomnia

2015-01-01
The American Academy of Sleep Medicine (AASM) commissioned five Workgroups to develop quality measures to optimize management and care for patients with common sleep disorders including insomnia. Following the AASM process for quality measure development, this document describes measurement methods for two desirable outcomes of therapy, improving sleep quality or satisfaction, and improving daytime function, and for four processes important to achieving these goals. To achieve the outcome of improving sleep quality or satisfaction, pre- and post-treatment assessment of sleep quality or satisfaction and providing an evidence-based treatment are recommended. To realize the outcome of improving daytime functioning, pre- and post-treatment assessment of daytime functioning, provision of an evidence-based treatment, and assessment of treatment-related side effects are recommended. All insomnia measures described in this report were developed by the Insomnia Quality Measures Workgroup and approved by the AASM Quality Measures Task Force and the AASM Board of Directors. The AASM recommends the use of these measures as part of quality improvement programs that will enhance the ability to improve care for patients with insomnia.

Commercialising genetically engineered animal biomedical products.
Sullivan, Eddie J; Pommer, Jerry; Robl, James M
2008-01-01
Research over the past two decades has increased the quality and quantity of tools available to produce genetically engineered animals. The number of potentially viable biomedical products from genetically engineered animals is increasing. However, moving from cutting-edge research to development and commercialisation of a biomedical product that is useful and wanted by the public has significant challenges. Even early stage development of genetically engineered animal applications requires consideration of many steps, including quality assurance and quality control, risk management, gap analysis, founder animal establishment, cell banking, sourcing of animals and animal-derived material, animal facilities, product collection facilities and processing facilities. These steps are complicated and expensive. Biomedical applications of genetically engineered animals have had some recent successes and many applications are well into development. As researchers consider applications for their findings, having a realistic understanding of the steps involved in the development and commercialisation of a product, produced in genetically engineered animals, is useful in determining the risk of genetic modification to the animal nu. the potential public benefit of the application.
Practice Guideline Recommendations on Perioperative Fasting: A Systematic Review.
Lambert, Eva; Carey, Sharon
2016-11-01
Traditionally, perioperative fasting consisted of being nil by mouth (NBM) from midnight before surgery and fasting postoperatively until recovery of bowel function. These outdated practices persist despite emerging evidence revealing that excessive fasting results in negative outcomes and delayed recovery. Various evidence-based, multimodal, enhanced recovery protocols incorporating minimized perioperative fasting have arisen to improve patient outcomes and streamline recovery, but implementation remains limited. This article aims to review current fasting guidelines, assess their quality, summarize relevant recommendations, and identify gaps in evidence. A systematic literature search of Medline and CINAHL and a manual search of relevant websites identified guidelines containing suitable grading systems and fasting recommendations. Guideline quality was assessed using the Appraisal of Guidelines Research and Evaluation (AGREE) tool. Grading systems were standardized to the American Society for Parenteral and Enteral Nutrition format and recommendations summarized based on grading and guideline quality. Nineteen guidelines were included. Rigor of development scores ranged from 29%-95%, with only 8 guidelines explicitly declaring the use of systematic methodology. Applicability scores were lowest, averaging 32%. Ten recommendation types were extracted and summarized. Strong and consistent evidence exists for the minimization of perioperative fasting, for a 2-hour preoperative fast after clear fluids, and for early recommencement of oral food and fluid intake postoperatively. This article presents several high-level recommendations ready for immediate implementation, while poorly graded and inconsistent recommendations reveal key areas for future research. Meanwhile, guideline quality requires improvement, especially regarding rigor of development and applicability, through systematic methodology, reporting transparency, and implementation strategies. © 2015 American Society for Parenteral and Enteral Nutrition.

2015-01-01
Over recent years, the development of molecular biology techniques has improved the hematological diseases diagnostic and follow-up. Consequently, these techniques are largely used in the biological screening of these diseases; therefore the Hemato-oncology molecular diagnostics laboratories must be actively involved in the accreditation process according the ISO 15189 standard. The French group of molecular biologists (GBMHM) provides requirements for the implementation of quality assurance for the medical molecular laboratories. This guideline states the recommendations for the pre-analytical, analytical (methods validation procedures, quality controls, reagents), and post-analytical conditions. In addition, herein we state a strategy for the internal quality control management. These recommendations will be regularly updated.

In this article, we describe how to include considerations about resource utilization when making recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. We focus on challenges with rating the confidence in effect estimates (quality of evidence) and incorporating resource use into evidence profiles and Summary of Findings (SoF) tables. GRADE recommends that important differences in resource use between alternative management strategies should be included along with other important outcomes in the evidence profile and SoF table. Key steps in considering resources in making recommendations with GRADE are the identification of items of resource use that may differ between alternative management strategies and that are potentially important to decision makers, finding evidence for the differences in resource use, making judgments regarding confidence in effect estimates using the same criteria used for health outcomes, and valuing the resource use in terms of costs for the specific setting for which recommendations are being made. With our framework, decision makers will have access to concise summaries of recommendations, including ratings of the quality of economic evidence, and better understand the implications for clinical decision making.

Background The Internet is a widely used source of information for patients searching for medical/health care information. While many studies have assessed existing medical/health care information on the Internet, relatively few have examined methods for design and delivery of such websites, particularly those aimed at the general public. Objective This study describes a method of evaluating material for new medical/health care websites, or for assessing those already in existence, which is correlated with higher rankings on Google's Search Engine Results Pages (SERPs). Methods A website quality assessment (WQA) tool was developed using criteria related to the quality of the information to be contained in the website in addition to an assessment of the readability of the text. This was retrospectively applied to assess existing websites that provide information about generic medicines. The reproducibility of the WQA tool and its predictive validity were assessed in this study. Results The WQA tool demonstrated very high reproducibility (intraclass correlation coefficient=0.95) between 2 independent users. A moderate to strong correlation was found between WQA scores and rankings on Google SERPs. Analogous correlations were seen between rankings and readability of websites as determined by Flesch Reading Ease and Flesch-Kincaid Grade Level scores. Conclusions The use of the WQA tool developed in this study is recommended as part of the design phase of a medical or health care information provision website, along with assessment of readability of the material to be used. This may ensure that the website performs better on Google searches. The tool can also be used retrospectively to make improvements to existing websites, thus, potentially enabling better Google search result positions without incurring the costs associated with Search Engine Optimization (SEO) professionals or paid promotion.

In many areas, decreases in the stratospheric ozone layer have resulted in an increase in ultraviolet-B (UV-B, 280-315 nm) radiation reaching the Earth's surface. The present study was conducted to evaluate the interactive effects of supplemental UV-B (sUV-B) and mineral nutrients on a tuber crop, potato (Solanum tuberosum L. var Kufri Badshah), under natural field conditions in a dry tropical environment. The nutrient treatments were the recommended dose of NPK (F(o)), 1.5 times the recommended dose of NPK (F(1)), 1.5 times the recommended dose of N (F(2)) and 1.5 times the recommended dose of K (F(3)). The response of potato plants to sUV-B varied with nutrient treatment and concentration. sUV-B adversely affected growth, yield and quality of tubers, causing an increase in reducing sugars in the tubers and thus reducing the economic value. Growth and fresh weight of tubers was maximal with sUV-B at 1.5 times recommended NPK, but the dry weight of tubers were highest with the recommended NPK dose. Reducing sugar content was lower in potato plants treated with sUV-B and the recommended NPK than with sUV-B and 1.5 times the recommended NPK. This study thus clearly shows that growing potato with 1.5 times the recommended NPK or 1.5 times the recommended dose of N/K does not alleviate the sUV-B induced changes in yield and quality of tubers compared to the recommended NPK dose. © 2010 German Botanical Society and The Royal Botanical Society of the Netherlands.
