    Canada began research on space-relevant biological life support systems in the early 1990s. Since that time Canadian capabilities have grown tremendously, placing Canada among the emerging leaders in biological life support systems. The rapid growth of Canadian expertise has been the result of several factors including a large and technically sophisticated greenhouse sector which successfully operates under challenging climatic conditions, well planned technology transfer strategies between the academic and industrial sectors, and a strong emphasis on international research collaborations. Recent activities such as Canada's contribution of the Higher Plant Compartment of the European Space Agency's MELiSSA Pilot Plant and the remote operation of the Arthur Clarke Mars Greenhouse in the Canadian High Arctic continue to demonstrate Canadian capabilities with direct applicability to advanced life support systems. There is also a significant latent potential within Canadian institutions and organizations with respect to directly applicable advanced life support technologies. These directly applicable research interests include such areas as horticultural management strategies (for candidate crops), growth media, food processing, water management, atmosphere management, energy management, waste management, imaging, environment sensors, thermal control, lighting systems, robotics, command and data handling, communications systems, structures, in-situ resource utilization, space analogues and mission operations. With this background and in collaboration with the Canadian aerospace industry sector, a roadmap for future life support contributions is presented here. This roadmap targets an objective of at least 50% food closure by 2050 (providing greater closure in oxygen, water recycling and carbon dioxide uptake). The Canadian advanced life support community has chosen to focus on lunar surface infrastructure and not low Earth orbit or transit systems (i.e. microgravity

    This paper explores Canadian public perceptions of a hypothetical scenario in which a radical increase in life expectancy results from advances in regenerative medicine. A national sample of 1231 adults completed an online questionnaire on stem cell research and regenerative medicine, including three items relating to the possibility of Canadians' average life expectancy increasing to 120 years by 2050. Overall, Canadians are strongly supportive of the prospect of extended lifespans, with 59% of the sample indicating a desire to live to 120 if scientific advances made it possible, and 47% of respondents agreeing that such increases in life expectancy are possible by 2050. The strongest predictors of support for radical life extension are individuals' general orientation towards science and technology and their evaluation of its plausibility. These results contrast with previous research, which has suggested public ambivalence for biomedical life extension, and point to the need for more research in this area. They suggest, moreover, that efforts to increase public awareness about anti-aging research are likely to increase support for the life-extending consequences of that research program.

  3. Tracing the Life Courses of Canadians

    Rajulton, Fernando

    1994-01-01

    Full Text Available This paper examines the life courses of Canadians through an event history analysis of data from the 1990 General Social Survey on Family and Friends. The sequences and the timing of transitions into various life course stages, and the durations of stay in those stages are analyzed through multiple-decrement life tables. Changes in the life courses over 10-year birth cohorts from 1910 to 1970 and differentials by gender are highlighted in the paper. The analysis reveals that what is traditionally thought of as a "typical" life course is experienced only by one-fourth to one-third of a cohort. With the increasing diversity of life course stages among younger cohorts, it would no longer be adequate to consider only the "typical" life stages in future analyses.

    Work-life balance has become a topic of increasing interest in the media as well as a concern among working Canadians. Since print media discourse can both reflect and shape societal values, cultural norms and ideals of workers in this country, it is important to understand this representation and its potential influence on the occupational engagement and life transitions of Canadian workers. Articles from four major Canadian newspapers published between 2003 and 2005 were used as data sources to examine the media construction of "work-life balance". Thematic analysis of 100 articles was performed using a modified affinity diagramming process. Representations within the Canadian print media conveyed both themes pertaining to the perceived experiences of imbalance and balance, as well as, a process of life balance. Obtaining balance was portrayed as an ongoing process during which an individual negotiates and sacrifices in an attempt to achieve his or her ideal level of balance. Environmental expectations and individual practices and perceptions were conveyed as reasons for the success or derailment of balance. The representations of work-life balance found in the Canadian print media were predominantly of professionals, focused on the demands of work and family, and did not appear to be a broad representation of the multiple realities that all Canadians face.

    Full Text Available AbstractWe construct cohort working life tables for Canadian men and women aged 50and older and, for comparison, corresponding period tables. The tables arederived using annual single-age time series of participation rates for 1976-2006from the master files of the Statistics Canada Labour Force Survey. The cohortcalculations are based on stochastic projections of mortality coupled withalternative assumptions about future participation rates. Separate tables areprovided for the years 1976, 1991, and 2006, thus spanning a period ofsubstantial gains in life expectancy and strong upward trends in femaleparticipation. Life expectancies based on the cohort tables are greater thanthose based on the period tables, for both men and women, and that is reflectedin increased retirement expectancies. For example, a male aged 50 in 1976could have expected to live three years longer and to have almost four moreyears in retirement, based on the male cohort table under medium assumptions,as compared with the corresponding period table.RésuméNous avons établis des tables de vie active par génération pour les Canadiens etCanadiennes âgés de 50 ans ou plus ainsi que des tables du momentcorrespondantes pour servir de comparaison.

    This study aims to catalogue and examine the following work-life flexibility policies at all 17 Canadian medical schools: maternity leave, paternity leave, adoption leave, extension of the probationary period for family responsibilities, part-time faculty appointments, job sharing, and child care. The seven work-life policies of Canadian medical schools were researched using a consistent and systematic method. This method involved an initial web search for policy information, followed by e-mail and telephone contact. The flexibility of the policies was scored 0 (least flexible) to 3 (most flexible). The majority of policies were easily accessible online. Work-life policies were scored out of 3, and average policy scores ranged from 0.47 for job sharing to 2.47 for part-time/work reduction. Across schools, total scores ranged from 7 to 16 out of 21. Variation in scores was noted for parenting leave and child care, whereas minimal variation was noted for other policies. Canadian medical schools are committed to helping medical faculty achieve work-life balance, but improvements can be made in the policies offered at all schools. Improving the quality of work flexibility policies will enhance working conditions and job satisfaction for faculty. This could potentially reduce Canada's loss of talented young academicians.

    The gambling landscape among provinces in Canada is diverse. Yet, few studies have investigated provincial differences related to life interference due to gambling. The objectives of the current study were to examine: (1) provincial differences with regard to gambling types and (2) if gender, family history of gambling, and alcohol or drug use while gambling were related to an increased likelihood of life interference in three Canadian provinces. Data were drawn from the 2013 and 2014 cycles of the Canadian Community Health Survey from Manitoba, Saskatchewan, and British Columbia (n = 30,150). Analyses were conducted stratified by provinces and also combined using logistic regression models. Provincial differences were noted with individuals from British Columbia compared to Manitoba being less likely to play VLTs outside of casinos, play live horse racing at a track or off track, and participate in sports gambling. Those in Saskatchewan compared to Manitoba were more likely to play VLTs inside a casino. When examining all provinces combined, family history of gambling was associated with increased odds of life interference. Gender was not associated with life interference. Provincial differences were noted, which may be in part related to differences in gambling landscapes. Family history of gambling may have clinical relevance for understanding which individuals may be more likely to experience life interference due to gambling. Further research is needed to clarify the link between alcohol and drug use while gambling and life interference due to gambling as the models in the current research were likely underpowered.

    Neurosurgical residents face a unique combination of challenges, including long duty hours, technically challenging cases, and uncertain employment prospects. We sought to assess the demographics, interests, career goals, self-rated happiness, and overall well-being of Canadian neurosurgery residents. A cross-sectional survey was developed and sent through the Canadian Neurosurgery Research Collaborative to every resident enrolled in a Canadian neurosurgery program as of April 1, 2016. We analyzed 76 completed surveys of 146 eligible residents (52% response rate). The median age was 29 years, with 76% of respondents being males. The most popular subspecialties of interest for fellowship were spine, oncology, and open vascular neurosurgery. The most frequent self-reported number of worked hours per week was the 80- to 89-hour range. The majority of respondents reported a high level of happiness as well as stress. Sense of accomplishment and fatigue were reported as average to high and overall quality of life was low for 19%, average for 49%, and high for 32%. Satisfaction with work-life balance was average for 44% of respondents and was the only tested domain in which significant dissatisfaction was identified (18%). Overall, respondents were highly satisfied with their choice of specialty, choice of program, surgical exposure, and work environment; however, intimidation was reported in 36% of respondents and depression by 17%. Despite a challenging residency and high workload, the majority of Canadian neurosurgery residents are happy and satisfied with their choice of specialty and program. However, work-life balance, employability, resident intimidation, and depression were identified as areas of active concern.

  12. Advanced Life Support Project Plan

    Science.gov (United States)

    2002-01-01

    Life support systems are an enabling technology and have become integral to the success of living and working in space. As NASA embarks on human exploration and development of space to open the space frontier by exploring, using and enabling the development of space and to expand the human experience into the far reaches of space, it becomes imperative, for considerations of safety, cost, and crew health, to minimize consumables and increase the autonomy of the life support system. Utilizing advanced life support technologies increases this autonomy by reducing mass, power, and volume necessary for human support, thus permitting larger payload allocations for science and exploration. Two basic classes of life support systems must be developed, those directed toward applications on transportation/habitation vehicles (e.g., Space Shuttle, International Space Station (ISS), next generation launch vehicles, crew-tended stations/observatories, planetary transit spacecraft, etc.) and those directed toward applications on the planetary surfaces (e.g., lunar or Martian landing spacecraft, planetary habitats and facilities, etc.). In general, it can be viewed as those systems compatible with microgravity and those compatible with hypogravity environments. Part B of the Appendix defines the technology development 'Roadmap' to be followed in providing the necessary systems for these missions. The purpose of this Project Plan is to define the Project objectives, Project-level requirements, the management organizations responsible for the Project throughout its life cycle, and Project-level resources, schedules and controls.

    2013-05-01

    This paper explores Canadian engineering employers' perceptions of and experiences with internationally educated engineers (recent immigrants to Canada) employed in their organisations for varying lengths of time. Qualitative data were collected from employers using focus group methodology. Findings reflected employers' observations of culturally different behaviours and characteristics in their internationally educated employees, employers' reactions to cultural differences ranging from negative attributions to tolerance, and the implementation of largely ad hoc intra-organisational strategies for managing cultural differences in employer-employee relationships. Findings exposed the lack of corporate intercultural competency in the Canadian engineering profession. Equity and gatekeeping implications are discussed.

    Aboriginal representation in Canadian correctional institutions has increased rapidly over the past decade. We calculated "years of life lost to incarceration" for Aboriginal and non-Aboriginal Canadians. Incarceration data from provincial databases were used conjointly with demographic data to estimate rates of incarceration and years of life lost to provincial incarceration in (BC) and federal incarceration, by Aboriginal status. We used the Sullivan method to estimate the years of life lost to incarceration. Aboriginal males can expect to spend approximately 3.6 months in federal prison and within BC spend an average of 3.2 months in custody in the provincial penal system. Aboriginal Canadians on average spend more time in custody than their non-Aboriginal counterparts. The ratio of the Aboriginal incarceration rate to the non-Aboriginal incarceration rate ranged from a low of 4.28 in Newfoundland and Labrador to a high of 25.93 in Saskatchewan. Rates of incarceration at the provincial level were highest among Aboriginals in Manitoba with an estimated rate of 1377.6 individuals in prison per 100,000 population (95% confidence interval [CI]: 1311.8-1443.4). The results indicate substantial differences in life years lost to incarceration for Aboriginal versus non-Aboriginal Canadians. In light of on-going prison expansion in Canada, future research and policy attention should be paid to the public health consequences of incarceration, particularly among Aboriginal Canadians.

  16. The Canadian National Retirement Risk Index: employing statistics Canada's LifePaths to measure the financial security of future Canadian seniors.

    This article measures a Canadian National Retirement Risk Index (NRRI). Originally developed by the Center for Retirement Research at Boston College, the NRRI is a forward-looking measure that evaluates the proportion of working-aged individuals who are at risk of not maintaining their standard of living in retirement. The Canadian retirement income system has been very effective in reducing elderly poverty, but our results suggest that it has been much less successful in maintaining the living standards of Canadians after retirement. Since the earlier years of the new millennium, we find that approximately one-third of retiring Canadians have been unable to maintain their working-age consumption after retirement—a trend that is projected to worsen significantly for future Canadian retirees. The release of the Canadian NRRI is timely given the widespread concern that the current Canadian retirement income system is inadequate. Many proposals have recently emerged to extend and/or enhance Canadian public pensions, and the NRRI is a tool to test their merit. The methodology underlying the Canadian NRRI is uniquely sophisticated and comprehensive on account of our employment of Statistics Canada’s LifePaths, a state-of-the-art stochastic microsimulation model of the Canadian population. For instance, the Canadian NRRI is novel in that it models all of the relevant sources of consumption before and after retirement, while accounting for important features that are typically neglected in retirement adequacy studies such as family size, the variation of consumption over a person’s lifetime, and the heterogeneity among the life courses of individuals.

    Full Text Available On June 18, 2015 the University of Calgary’s School of Public Policy hosted the symposium The Trans-Pacific Partnership and Beyond: Advancing Canadian Trade and Investment in Asia, at the Canadian War Museum. The School was honoured to have Dr. Randolph Mank present the keynote address at this event who brings over thirty years of public and private sector experience in Asia to his analysis of Canadian relations in Asia. A three-time Canadian Ambassador in the Asian region, having served in Indonesia, Malaysia and Pakistan, Mank also held the position of Senior Advisor and Vice President Asia for Blackberry and currently lives in Singapore. Presenting a policy prescription for Canadian-Asian relations over the next five years or so, Mank shares a personal “Top 10” list of specific things Canada should do to advance national and business interests in Asia. Although expanding trade linkages in the region is obviously crucial for Canada, Mank’s recommendations are positioned within the broader framework of strengthening our diplomatic platform and development assistance in the region. Mank concludes that if Canada does not increase its engagement and investment in Asia, we won’t be an influential player in the evolving and highly integrated new world order. One might agree with every recommendation, or once might quibble with the government-centered focus of his prescriptions; most certainly, some Canadian firms have been successful in Asia and we could learn from their experiences. That said, Dr. Mank speaks from authority and we are pleased to publish his speech as a valuable contribution to a more informed and public debate on Canada’s future role in Asia.

    2017-09-01

    This study examined the relationship between work dissatisfaction and sleep problems among Canadian adults in the latter half of life, as well as how gender and social contact moderate this relationship. Data were obtained from the Canadian General Social Survey, Cycle 21 (2007), which sampled adults aged 45 and older in 2007. Analyses focused on individuals with employment as their main activity. Analyses show that work dissatisfaction positively predicts trouble sleeping. There are no significant gender differences in this relationship. Social contact with friends buffers this relationship, but social contact with family does not, and buffering does not vary significantly between men and women. This research contributes to knowledge on sleep problems by showing that work dissatisfaction is adversely associated with sleep problems among Canadians in the latter half of life, but social contact with friends can weaken this deleterious relationship.

    The Canadian Arctic has vast freshwater resources, and fish are important in the diet of many Northerners. Mercury is a contaminant of concern because of its potential toxicity and elevated bioaccumulation in some fish populations. Over the last decade, significant advances have been made in characterizing the cycling and fate of mercury in these freshwater environments. Large amounts of new data on concentrations, speciation and fluxes of Hg are provided and summarized for water and sediment, which were virtually absent for the Canadian Arctic a decade ago. The biogeochemical processes that control the speciation of mercury remain poorly resolved, including the sites and controls of methylmercury production. Food web studies have examined the roles of Hg uptake, trophic transfer, and diet for Hg bioaccumulation in fish, and, in particular, advances have been made in identifying determinants of mercury levels in lake-dwelling and sea-run forms of Arctic char. In a comparison of common freshwater fish species that were sampled across the Canadian Arctic between 2002 and 2009, no geographic patterns or regional hotspots were evident. Over the last two to four decades, Hg concentrations have increased in some monitored populations of fish in the Mackenzie River Basin while other populations from the Yukon and Nunavut showed no change or a slight decline. The different Hg trends indicate that the drivers of temporal change may be regional or habitat-specific. The Canadian Arctic is undergoing profound environmental change, and preliminary evidence suggests that it may be impacting the cycling and bioaccumulation of mercury. Further research is needed to investigate climate change impacts on the Hg cycle as well as biogeochemical controls of methylmercury production and the processes leading to increasing Hg levels in some fish populations in the Canadian Arctic.

  1. An Analysis of Canadian Psychiatric Mental Health Nursing through the Junctures of History, Gender, Nursing Education, and Quality of Work Life in Ontario, Manitoba, Alberta, and Saskatchewan

    Science.gov (United States)

    2013-01-01

    A society that values mental health and helps people live enjoyable and meaningful lives is a clear aspiration echoed throughout our Canadian health care system. The Mental Health Commission of Canada has put forth a framework for a mental health strategy with goals that reflect the virtue of optimal mental health for all Canadians (Mental Health Commission Canada, 2009). Canadian nurses, the largest group of health care workers, have a vital role in achieving these goals. In Canada, two-thirds of those who experience mental health problems do not receive mental health services (Statistics Canada, 2003). Through a gendered, critical, and sociological perspective the goal of this paper is to further understand how the past has shaped the present state of psychiatric mental health nursing (PMHN). This integrative literature review offers a depiction of Canadian PMHN in light of the intersections of history, gender, education, and quality of nursing work life. Fourteen articles were selected, which provide a partial reflection of contemporary Canadian PMHN. Findings include the association between gender and professional status, inconsistencies in psychiatric nursing education, and the limitations for Canadian nurse practitioners to advance the role of the psychiatric mental health nurse practitioner.

  2. Learning to Control Advanced Life Support Systems

    Advanced life support systems have many interacting processes and limited resources. Controlling and optimizing advanced life support systems presents unique challenges. In particular, advanced life support systems are nonlinear coupled dynamical systems and it is difficult for humans to take all interactions into account to design an effective control strategy. In this project. we developed several reinforcement learning controllers that actively explore the space of possible control strategies, guided by rewards from a user specified long term objective function. We evaluated these controllers using a discrete event simulation of an advanced life support system. This simulation, called BioSim, designed by Nasa scientists David Kortenkamp and Scott Bell has multiple, interacting life support modules including crew, food production, air revitalization, water recovery, solid waste incineration and power. They are implemented in a consumer/producer relationship in which certain modules produce resources that are consumed by other modules. Stores hold resources between modules. Control of this simulation is via adjusting flows of resources between modules and into/out of stores. We developed adaptive algorithms that control the flow of resources in BioSim. Our learning algorithms discovered several ingenious strategies for maximizing mission length by controlling the air and water recycling systems as well as crop planting schedules. By exploiting non-linearities in the overall system dynamics, the learned controllers easily out- performed controllers written by human experts. In sum, we accomplished three goals. We (1) developed foundations for learning models of coupled dynamical systems by active exploration of the state space, (2) developed and tested algorithms that learn to efficiently control air and water recycling processes as well as crop scheduling in Biosim, and (3) developed an understanding of the role machine learning in designing control systems for

    To assess the cost-effectiveness of gemcitabine (G), G + 5-fluorouracil, G + capecitabine, G + cisplatin, G + oxaliplatin, G + erlotinib, G + nab-paclitaxel (GnP), and FOLFIRINOX in the treatment of advanced pancreatic cancer from a Canadian public health payer's perspective, using data from a recently published Bayesian network meta-analysis. Analysis was conducted through a three-state Markov model and used data on the progression of disease with treatment from the gemcitabine arms of randomized controlled trials combined with estimates from the network meta-analysis for the newer regimens. Estimates of health care costs were obtained from local providers, and utilities were derived from the literature. The model estimates the effect of treatment regimens on costs and quality-adjusted life-years (QALYs) discounted at 5% per annum. At a willingness-to-pay (WTP) threshold of greater than $30,666 per QALY, FOLFIRINOX would be the most optimal regimen. For a WTP threshold of $50,000 per QALY, the probability that FOLFIRINOX would be optimal was 57.8%. There was no price reduction for nab-paclitaxel when GnP was optimal. From a Canadian public health payer's perspective at the present time and drug prices, FOLFIRINOX is the optimal regimen on the basis of the cost-effectiveness criterion. GnP is not cost-effective regardless of the WTP threshold. Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights reserved.

    2013-01-01

    An Advanced Stirling Radioisotope Generator (ASRG) power supply is being developed by the Department of Energy (DOE) in partnership with NASA for potential future deep space science missions. Unlike previous radioisotope power supplies for space exploration, such as the passive MMRTG used recently on the Mars Curiosity rover, the ASRG is an active dynamic power supply with moving Stirling engine mechanical components. Due to the long life requirement of 17 years and the dynamic nature of the Stirling engine, the ASRG project faced some unique challenges trying to establish full confidence that the power supply will function reliably over the mission life. These unique challenges resulted in the development of an overall life certification plan that emphasizes long-term Stirling engine test and inspection when analysis is not practical. The ASRG life certification plan developed is described.

    This edited book offers further advances, new perspectives, and developments from world leaders in the field of through-life engineering services (TES). It builds up on the earlier book by the same authors entitled: “Through-life Engineering Services: Motivation, Theory and Practice.” This compendium introduces and discusses further, the developments in workshop-based and 'in situ' maintenance and support of high-value engineering products, as well as the application of drone technology for autonomous and self-healing product support. The links between ‘integrated planning’ and planned obsolescence, risk and cost modelling are also examined. The role of data, information, and knowledge management relative to component and system degradation and failure is also presented. This is supported by consideration of the effects upon the maintenance and support decision by the presence of 'No Fault Found' error signals within system data. Further to this the role of diagnostics and prognostics is also discusse...

    Full Text Available While systemic shortcomings in meeting the needs of individuals with progressive chronic illnesses at the end of life have been well documented, there is growing interest in improving both care and quality of life for persons with advanced chronic obstructive pulmonary disease (COPD. For instance, the American Thoracic Society has issued an official statement on palliative care for patients with respiratory diseases, affirming that the prevention, relief, reduction and soothing of symptoms “without affecting a cure” must become an integral component of standard care. A recent Medline search located 1015 articles related to palliative or end-of-life care for people with COPD published between 2001 and 2008, compared with only 336 articles published before 2001. To address the needs of Canadian patients, an interdisciplinary consensus meeting, funded by the Canadian Institutes of Health Research and supported by the Canadian Thoracic Society, the Canadian Respiratory Health Professionals and the Canadian Lung Association was convened in Toronto, Ontario, on November 22, 2008, to begin examining the quality of end-of-life care for individuals with COPD in Canada. The present report summarizes the background to and outcomes of this consensus meeting.

    Full Text Available Applying the theory of the intergenerational transmission of divorce, this paper examines the consequences of parental divorce on three aspects of the life course of children: union formation, nonmarital fertility, and marital dissolution. The 1995 Canadian General Social Survey (GSS is used to estimate various regression models (Cox proportional hazards. Results show that children of divorced parents have a significantly higher likelihood to have births outside of marriage, enter into cohabiting unions, and to experience higher levels of divorce. Throughout the paper, attention is placed on the markedly different behaviour observed in Quebec compared to elsewhere in Canada.

  10. Analysis of Tax-deductible Interest Payments for Re-advanceable Canadian Mortgages

    Naseem, Almas; Reesor, Mark

    2011-11-01

    According to Canadian tax law the interest on loans used for investment purposes is tax deductible while interest on personal mortgage loans is not. One way of transforming from non-tax deductible to tax deductible interest expenses is to borrow against home equity to make investments. A re-advanceable mortgage is a product specifically designed to take advantage of this tax discrepancy. Using simulation we study the risk associated with the re-advanceable mortgage strategy to provide a better description of the mortgagor's position. We assume that the mortgagor invests the borrowings secured by home equity into a single risky asset (e.g., stock or mutual fund) whose evolution is described by geometric Brownian motion (GBM). With a re-advanceable mortgage we find that the average mortgage payoff time is less than the original mortgage term. However, there is considerable variation in the payoff times with a significant probability of a payoff time exceeding the original mortgage term. Higher income homeowners enjoy a payoff time distribution with both a lower average and a lower standard deviation than low-income homeowners. Thus this strategy is most beneficial to those with the highest income. We also find this strategy protects the homeowner in the event of job loss. This work is important to lenders, financial planners and homeowners to more fully understand the benefits and risk associated with this strategy.

    2016-01-01

    The NASA Advanced Exploration Systems (AES) Life Support Systems (LSS) project strives to develop reliable, energy-efficient, and low-mass spacecraft systems to provide environmental control and life support systems (ECLSS) critical to enabling long duration human missions beyond low Earth orbit (LEO). Highly reliable, closed-loop life support systems are among the capabilities required for the longer duration human space exploration missions assessed by NASA's Habitability Architecture Team (HAT). The LSS project is focused on four areas: architecture and systems engineering for life support systems, environmental monitoring, air revitalization, and wastewater processing and water management. Starting with the international space station (ISS) LSS systems as a point of departure (where applicable), the mission of the LSS project is three-fold: 1. Address discrete LSS technology gaps 2. Improve the reliability of LSS systems 3. Advance LSS systems towards integrated testing on the ISS. This paper summarized the work being done in the four areas listed above to meet these objectives. Details will be given on the following focus areas: Systems Engineering and Architecture- With so many complex systems comprising life support in space, it is important to understand the overall system requirements to define life support system architectures for different space mission classes, ensure that all the components integrate well together and verify that testing is as representative of destination environments as possible. Environmental Monitoring- In an enclosed spacecraft that is constantly operating complex machinery for its own basic functionality as well as science experiments and technology demonstrations, it's possible for the environment to become compromised. While current environmental monitors aboard the ISS will alert crew members and mission control if there is an emergency, long-duration environmental monitoring cannot be done in-orbit as current methodologies

    Language is an important determinant of health, but analyses of linguistic inequalities in mortality are scant, especially for Canadian linguistic groups with European roots. We evaluated the life expectancy gap between the Francophone majority and Anglophone minority of Québec, Canada, both over time and across major provincial areas. Arriaga's method was used to estimate the age and cause of death groups contributing to changes in the life expectancy gap at birth between 1989-1993 and 2002-2006, and to evaluate patterns across major provincial areas (metropolitan Montréal, other metropolitan centres, and small cities/rural areas). Life expectancy at birth was greater for Anglophones, but the gap decreased over time by 1.3 years (52% decline) in men and 0.9 years (47% decline) in women, due to relatively sharper reductions in Francophone mortality from several causes, except lung cancer which countered reductions in women. The life expectancy gap in 2002-2006 was widest in other metropolitan centres (men 5.1 years, women 3.2 years), narrowest in small cities/rural areas (men 0.8 years, women 0.7 years), and tobacco-related causes were the main contributors. Only young Anglophones time, but varied across areas of Québec. Tobacco-related causes accounted for the majority of the current life expectancy gap.

    Knowledge about individual and interpersonal correlates of violence in Canadian seniors is limited. This study identifies correlates of current and past violence by intimate partner and family member(s) in community-dwelling Canadian seniors, while accounting for childhood adverse circumstances. We performed logistic regression analysis of baseline data from a longitudinal study of community-dwelling individuals aged 65 to 74 years and living in Kingston (Ontario) and Saint-Hyacinthe (Quebec). Domestic violence was assessed using the Hurt- Insult-Threaten-Scream (HITS) screening tool. Odds ratios (ORs) are reported with 95% confidence intervals (CIs). Current violence of a psychological nature was reported by 18% of the sample. Women were at greater risk of current and lifetime violence perpetrated by a family member (current violence: adjusted OR = 1.83; 95% CI: 1.02-3.30) as well as experiencing violence from their intimate partner in their lifetime than were men (adjusted OR = 2.48; 95% CI: 1.40-4.37). Risk factors have accumulated over the life course that were found to be consistently associated with both current and lifetime violence included having witnessed violence at home in childhood (lifetime violence by family member: adjusted OR = 9.46; 95% CI: 5.11-17.52), as well as poor quality of relationships with intimate partners, family and friends. Our research documents the ongoing impact of early adversity on subsequent partner and family violence in Canada. Findings identify some preventable factors associated with current psychological violence and past violence among community dwelling Canadian seniors.

  14. Life cycle assessment of camelina oil derived biodiesel and jet fuel in the Canadian Prairies

    2014-01-01

    This study evaluated the environmental impact of biodiesel and hydroprocessed renewable jet fuel derived from camelina oil in terms of global warming potential, human health, ecosystem quality, and energy resource consumption. The life cycle inventory is based on production activities in the Canadian Prairies and encompasses activities ranging from agricultural production to oil extraction and fuel conversion. The system expansion method is used in this study to avoid allocation and to credit input energy to co-products associated with the products displaced in the market during camelina oil extraction and fuel processing. This is the preferred allocation method for LCA analysis in the context of most renewable and sustainable energy programs. The results show that greenhouse gas (GHG) emissions from 1 MJ of camelina derived biodiesel ranged from 7.61 to 24.72 g CO 2 equivalent and 3.06 to 31.01 kg CO 2 /MJ equivalent for camelina HRJ fuel. Non-renewable energy consumption for camelina biodiesel ranged from 0.40 to 0.67 MJ/MJ; HRJ fuel ranged from − 0.13 to 0.52 MJ/MJ. Camelina oil as a feedstock for fuel production accounted for the highest contribution to overall environmental performance, demonstrating the importance of reducing environmental burdens during the agricultural production process. Attaining higher seed yield would dramatically lower environmental impacts associated with camelina seed, oil, and fuel production. The lower GHG emissions and energy consumption associated with camelina in comparison with other oilseed derived fuel and petroleum fuel make camelina derived fuel from Canadian Prairies environmentally attractive. - Highlights: • LCA of camelina-derived biodiesel and jet fuel was based on the Canadian Prairies. • Overall, camelina-derived biodiesel had lower GHG emissions than is biojet fuel. • Camelina jet fuel had lower non-renewable energy (NRE) use than its biodiesel. • Camelina biofuels reduced GHG emissions and NRE use

    Background. School is an integral component of the life of a child, and thus quality of school life is an important part of the overall quality of life experienced by a child. There are a few instruments available to measure the quality of school life but they are often not available in English, or they are not appropriate for use alongside other instruments in a survey of young children. The Quality of Life in School (QoLS) instrument is a short, self-report measure to assess elementary school students' perception of their quality of school life in four domains. The instrument was developed in Israel and has been validated among Hebrew-speaking children. The aim of the current study was to evaluate the psychometric properties of the QoLS measure in Canadian elementary school children. Methods. A total of 629 children attending grades 4-6 were recruited in a population-based cross-sectional study. The QoLS measure was administered to participating children by trained research assistants. In addition, their socio-demographic details and academic data were also obtained. The psychometric testing included exploratory factor analysis and reliability estimation using internal consistency (Cronbach's Alpha). Construct validity was investigated using the known groups comparisons for discriminative validity and via convergent validity. Results. A four-factor structure was generated explaining 39% of the total variance in the model. The results showed good internal consistency and acceptable floor and ceiling effects. Cronbach's Alpha ranged from 0.75 to 0.93. Known groups comparisons showed that the QoLS measure discriminated well between subgroups on the basis of gender, grade, and academic achievement, thus providing evidence of construct validity. The convergent validity was also appropriate with all the four domains demonstrating moderate to strong correlations to each other and to the total QoLS score. Conclusions. QoLS appears to be a valid and reliable measure for

    Medical end-of-life practices are hotly debated in Canada, and data from other countries are used to support arguments. The objective of this pilot study was twofold: to adapt and validate a questionnaire designed to measure the prevalence of these practices in Canada and the underlying decision-making process, and to assess the feasibility of a nationally representative study. In phase 1, questionnaires from previous studies were adapted to the Canadian context through consultations with a multidisciplinary committee and based on a scoping review. The modified questionnaire was validated through cognitive interviews with 14 physicians from medical specialties associated with a higher probability of being involved with dying patients recruited by means of snowball sampling. In phase 2, we selected a stratified random sample of 300 Canadian physicians in active practice from a national medical directory and used the modified tailored method design for mail and Web surveys. There were 4 criteria for success: modified questions are clearly understood; response patterns for sensitive questions are similar to those for other questions; respondents are comparable to the overall sampling frame; and mean questionnaire completion time is less than 20 minutes. Phase 1: main modifications to the questionnaire were related to documentation of all other medical practices (including practices intended to prolong life) and a question on the proportionality of drugs used. The final questionnaire contained 45 questions in a booklet style. Phase 2: of the 280 physicians with valid addresses, 87 (31.1%) returned the questionnaire; 11 of the 87 declined to participate, for a response rate of 27.1% (n = 76). Most respondents (64 [84%]) completed the mail questionnaire. All the criteria for success were met. It is feasible to study medical end-of-life practices, even for practices that are currently illegal, including the intentional use of lethal drugs. Results from this pilot study

    We investigated the associations among self-perceived work and life stress, trouble sleeping, physical activity and body weight among Canadian adults, and tested whether trouble sleeping and physical activity moderated the relationship between work/life stress and body weight, and whether work/life stress and physical activity moderated the relationship between trouble sleeping and body weight. Data on 13,926 Canadian adults aged 20years and older were derived from the nationally representative 2012 Canadian Community Health Survey. After adjusting for age, sex, education level, household income, marital status and job insecurity, self-perceived work and life stress and trouble sleeping were associated with a higher BMI. The associations of work and life stress with higher BMI were independent of trouble sleeping and physical activity in addition to other covariates, while that of trouble sleeping and higher BMI was independent of work and life stress. Results further indicated that trouble sleeping among inactive participants was related to a higher BMI; however, this relationship was almost null for adults who self-reported being physically active for about 8h/week. These findings suggest that work and life stress are both associated with excess weight in adults, regardless of physical activity level, while the link of trouble sleeping with BMI varies by physical activity level. Future research is necessary to determine whether reducing work and life stress and improving sleep habits would benefit the prevention of weight gain and obesity. Copyright © 2016 Elsevier Inc.

  19. Nonlinear Dynamic Models in Advanced Life Support

    Science.gov (United States)

    Jones, Harry

    2002-01-01

    To facilitate analysis, ALS systems are often assumed to be linear and time invariant, but they usually have important nonlinear and dynamic aspects. Nonlinear dynamic behavior can be caused by time varying inputs, changes in system parameters, nonlinear system functions, closed loop feedback delays, and limits on buffer storage or processing rates. Dynamic models are usually cataloged according to the number of state variables. The simplest dynamic models are linear, using only integration, multiplication, addition, and subtraction of the state variables. A general linear model with only two state variables can produce all the possible dynamic behavior of linear systems with many state variables, including stability, oscillation, or exponential growth and decay. Linear systems can be described using mathematical analysis. Nonlinear dynamics can be fully explored only by computer simulations of models. Unexpected behavior is produced by simple models having only two or three state variables with simple mathematical relations between them. Closed loop feedback delays are a major source of system instability. Exceeding limits on buffer storage or processing rates forces systems to change operating mode. Different equilibrium points may be reached from different initial conditions. Instead of one stable equilibrium point, the system may have several equilibrium points, oscillate at different frequencies, or even behave chaotically, depending on the system inputs and initial conditions. The frequency spectrum of an output oscillation may contain harmonics and the sums and differences of input frequencies, but it may also contain a stable limit cycle oscillation not related to input frequencies. We must investigate the nonlinear dynamic aspects of advanced life support systems to understand and counter undesirable behavior.

    Buckley, Nicole; Johnson-Green, Perry; Lefebvre, Luc

    As the pace of human exploration of space is accelerated, the need to address the challenges of long-duration human missions becomes imperative. Working with limited resources, we must determine the most effective way to meet this challenge. A great deal of science management centres on "applied" versus "basic" research as the cornerstone of a program. We have chosen to largely ignore such a labeling of science and concentrate on quality, as determined by peer review, as the primary criterion for science selection. Space Life Sciences is a very young science and access to space continues to be difficult. Because we have few opportunities for conducting science, and space life science is very challenging, we are comfortable maintaining a very high bar for selection. In order to ensure adequate depth to our community we have elected to concentrate our efforts. Working in concert with members of the community, we have identified specific areas of focus that are chosen by their importance in space, but also according to Canada's strength in the terrestrial counterpart of the research. It is hoped that through a balanced but highly competitive program with the emphasis on quality, Canadian scientists can contribute to making space a safer, more welcoming place for our astronauts.

    Advertisements as well as contemporary literature and films often depict older adults as sexually undesirable and unattractive, which reinforces the stereotype that they are nonsexual. However, the evolving discourses of successful aging emphasize that active engagement in life is a key element of healthy aging and as such, have been influencing the ways that older adults' sexuality is represented. This paper explores how popular newspapers and magazines in Canada construct and portray later life sexuality within the context of online dating. We retrieved 144 newspaper and magazine articles about later life online dating that were published between 2009 and 2011. Our thematic and discursive analyses of the articles generated six themes. Of 144 articles, 13% idealized sexuality (sexual attractiveness and optimal sexual engagement) for older adults. The articles portrayed sexual interests and functioning as declining in later life (19%) more often than sustaining (15%). Approximately 15% of the articles suggested that older adults should explore new techniques to boost sexual pleasure, thereby medicalizing and ameliorating sexual decline. In addition, the articles challenged the stereotype of older adults as non-sexual and claimed that sexual engagement in later life was valuable as it contributed to successful aging. We address the paradox in the articles' positive portrayals of older adults' sexuality and the tensions that arise between the two distinct ideals of sexuality that they advance.

    Normative data for the SF-36 measure of health-related quality of life (HRQOL) exist for those over 25 years of age, based on data from the population-based Canadian Multicentre Osteoporosis Study (CaMos). CaMos recently recruited a sample of young Canadians aged between 16 and 24 years. The purpose of this study was to develop normative SF-36 data for this age group. After direct standardization to the Canadian population, means, standard deviations (SD), 95% confidence intervals and percentage at floor and ceiling were produced for the eight domain and two summary scores of the SF-36. Domains are scored from 0 (poor) to 100 (excellent). Summary scores are standardized to a mean of 50, with scores over 50 representing better than average and below 50 poorer than average function. Separate analyses were completed for men and women, and for those 16-19 years and 20-24 years. The 1,001 community-based participants consisted of 474 men and 527 women from nine CaMos centres across Canada. Mean Physical Component Summary scores were 53.9 (SD = 6.9) and 53.3 (SD = 5.7) for young men and women, respectively. The equivalent Mental Component Summary scores were 49.3 (SD = 9.7) and 48.8 (SD = 8.9). In general, men scored somewhat higher than women, and younger (16-19 years) women scored higher than older (20-24 years) women, although the differences were small. HRQOL is good in this cohort of young Canadians. Both men and women scored somewhat better on physically than mentally oriented domains. In general, Canadian scores were similar to those of the US, while a comparable Swedish sample scored higher than both countries on most domains. Results underscore the importance of taking country, age and gender into consideration when using normative data.

    Full Text Available Abstract Background Complementary feeding is currently recommended after six months of age, when the nutrients in breast milk alone are no longer adequate to support growth. Few studies have examined macro- and micro-nutrient intakes from complementary foods (CF only. Our purpose was to assess the sources and nutritional contribution of CF over the first year of life. Methods In July 2003, a cross-sectional survey was conducted on a nationally representative sample of mothers with infants aged three to 12 months. The survey was administered evenly across all regions of the country and included a four-day dietary record to assess infants' CF intakes in household (tablespoon measures (breast milk and formula intakes excluded. Records from 2,663 infants were analyzed for nutrient and CF food intake according to 12 categories. Mean daily intakes for infants at each month of age from CF were pooled and compared to the Dietary Reference Intakes for the respective age range. Results At three months of age, 83% of infants were already consuming infant cereals. Fruits and vegetables were among the most common foods consumed by infants at all ages, while meats were least common at all ages except 12 months. Macro- and micro-nutrient intakes from CF generally increased with age. All mean nutrient intakes, except vitamin D and iron, met CF recommendations at seven to 12 months. Conclusions Complementary foods were introduced earlier than recommended. Although mean nutrient intakes from CF at six to 12 months appear to be adequate among Canadian infants, further attention to iron and vitamin D intakes and sources may be warranted.

    Health-related quality of life (HRQoL) assessment is recognized as an important outcome in the evaluation of different therapeutic regimens for persons with haemophilia. The Canadian Haemophilia Outcomes-Kids' Life Assessment Tool (CHO-KLAT) is a disease-specific measure of HRQoL for 4 to 18-year-old boys with haemophilia. The purpose of this study was to extend this disease-specific, child-centric, outcome measure for use in international clinical trials. We adapted the North American English CHO-KLAT version for use in five countries: France, Germany, the Netherlands, Spain and the United Kingdom (UK). The process included four stages: (i) translation; (ii) cognitive debriefing; (iii) validity assessment relative to the PedsQL (generic) and the Haemo-QoL (disease-specific) and (iv) assessment of inter and intra-rater reliability. Cognitive debriefing was performed in 57 boys (mean age 11.4 years), validation was performed in 144 boys (mean age 11.0 years) and reliability was assessed for a subgroup of 64 boys (mean age 12.0 years). Parents also participated. The mean scores reported by the boys were high: CHO-KLAT 77.0 (SD = 11.2); PedsQL 83.8 (SD = 11.9) and Haemo-QoL 79.6 (SD = 11.5). Correlations between the CHO-KLAT and PedsQL ranged from 0.63 in Germany to 0.39 in the Netherlands and Spain. Test-retest reliability (concordance) for child self-report was 0.67. Child-parent concordance was slightly lower at 0.57. The CHO-KLAT has been fully culturally adapted and validated for use in five different languages and cultures (in England, the Netherlands, France, Germany and Spain) where treatment is readily available either on demand or as prophylaxis. © 2014 John Wiley & Sons Ltd.

  10. The life, achievements and legacy of a great Canadian investigator: Professor Boris Petrovich Babkin (1877-1950).

    The present paper reviews the life and achievements of Professor Boris Petrovich Babkin (MD DSc LLD). History is only worth writing about if it teaches us about the future; therefore, this historical review concludes by describing what today's and future gastrointestinal physiologists could learn from Dr Babkin's life. Dr Babkin was born in Russia in 1877. He graduated with an MD degree from the Military Medical Academy in St Petersburg, Russia, in 1904. Not being attracted to clinical practice, and after some hesitation concerning whether he would continue in history or basic science of medicine, he entered the laboratory of Professor Ivan Petrovich Pavlov. Although he maintained an interest in history, in Pavlov's exciting environment he became fully committed to physiology of the gastrointestinal system. He advanced quickly in Russia and was Professor of Physiology at the University of Odessa. In 1922, he was critical of the Bolshevik revolution, and after a short imprisonment, he was ordered to leave Russia. He was invited with his family by Professor EH Starling (the discoverer of secretin) to his department at University College, London, England. Two years later, he was offered a professorship in Canada at Dalhousie University, Halifax, Nova Scotia. After contributing there for four years, he joined McGill University, Montreal, Quebec, in 1928 as Research Professor. He remained there for the rest of his career. Between 1940 and 1941, he chaired the Department, and following retirement, he remained as Research Professor. At the invitation of the world-famous neurosurgeon, Wilder Penfield, Dr Babkin continued as Research Fellow in the Department of Neurosurgery until his death in 1950 at age 73. His major achievements were related to establishing the concept of brain-gut-brain interaction and the influence of this on motility, as well as on interface of multiple different cells, nerves and hormones on secretory function. He had a major role in the rediscovery

    The requirements for a human life support system for long-duration space missions are reviewed. The system design of a controlled ecological life support system is briefly described, followed by a more detailed account of the study of the conceptual design of a Lunar Based CELSS. The latter is to provide a safe, reliable, recycling lunar base life support system based on a hybrid physicochemical/biological representative technology. The most important conclusion reached by this study is that implementation of a completely recycling CELSS approach for a lunar base is not only feasible, but eminently practical. On a cumulative launch mass basis, a 4-person Lunar Base CELSS would pay for itself in approximately 2.6 years relative to a physicochemical air/water recycling system with resupply of food from the Earth. For crew sizes of 30 and 100, the breakeven point would come even sooner, after 2.1 and 1.7 years, respectively, due to the increased mass savings that can be realized with the larger plant growth units. Two other conclusions are particularly important with regard to the orientation of future research and technology development. First, the mass estimates of the Lunar Base CELSS indicate that a primary design objective in implementing this kind of system must be to minimized the mass and power requirement of the food production plant growth units, which greatly surpass those of the other air and water recycling systems. Consequently, substantial research must be directed at identifying ways to produce food more efficiently. On the other hand, detailed studies to identify the best technology options for the other subsystems should not be expected to produce dramatic reductions in either mass or power requirement of a Lunar Base CELSS. The most crucial evaluation criterion must, therefore, be the capability for functional integration of these technologies into the ultimate design of the system. Secondly, this study illustrates that existing or near

    Programs provided by the Korea Association of Cardiopulmonary Resuscitation include Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Korean Advanced Life Support (KALS). However, programs pertinent to dental care are lacking. Since 2015, related organizations have been attempting to develop a Dental Advanced Life Support (DALS) program, which can meet the needs of the dental environment. Generally, for initial management of emergency situations, basic life support is most important. However, emergencies in young children mostly involve breathing. Therefore, physicians who treat pediatric dental patients should learn PALS. It is necessary for the physician to regularly renew training every two years to be able to immediately implement professional skills in emergency situations. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is absolutely necessary to be able to immediately implement professional skills in emergency situations.

    2011-11-01

    Full Text Available Findings that detail the social organization of day-to-day practices associated with the Canadian government policy of mandatory HIV testing of permanent residence applicants to Canada are reported. Institutional ethnography was used to investigate interactions between HIV-positive applicants and immigration physicians during the immigration medical examination. A composite narrative recounts details of a woman applicant's discovery through immigration testing that she was living with HIV. Mandatory HIV testing gives rise to serious difficulties for applicants to Canada living with HIV. Applicant, physician and federal state employee work practices associated with mandatory HIV testing are analysed. These practices contribute to the ideological work of the Canadian state, where interest bounds up in the examination serve the state and not the applicant. Findings should be useful for Canadian immigration policy makers who wish to develop constructive and functional strategies to address issues that matter in people's lives

    The purpose of this study was to further validate a novel instrument to measure satisfaction with end-of-life care, called the Canadian Health Care Evaluation Project (CANHELP) questionnaire. Data were collected by a cross-sectional survey of patients who had advanced, life-limiting illnesses and their family caregivers, and who completed CANHELP, a global rating of satisfaction, and a quality of life questionnaire. We conducted factor analysis, assessed internal consistency using Cronbach's alpha, and evaluated construct validity by describing the correlation amongst CANHELP, global rating of satisfaction and the quality of life questionnaire scores. There were 361 patient and 193 family questionnaires available for analysis. In the factor analysis, we identified six easily interpretable factors which explained 55.4% and 60.2% of the variance for the patient and caregiver questionnaire, respectively. For the patient version, the subscales derived from these factors were Relationship with Doctors, Illness Management, Communication, Decision-Making, Role of the Family, and Your Well-being. For the family questionnaire, the factors were Relationship with Doctors, Characteristics of Doctors and Nurses, Illness Management, Communication and Decision-Making, Your Involvement, and Your Well-being. Each subscale for each questionnaire had acceptable to excellent internal consistency (Cronbach's alpha ranged from 0.69-0.94). We observed good correlations between the CANHELP overall satisfaction score and global rating of satisfaction (correlation coefficient 0.49 and 0.63 for patient and family, respectively) which was greater than the correlations between CANHELP and the quality of life instruments. We conclude that the CANHELP Questionnaire is a valid and internally consistent instrument to measure satisfaction with end-of-life care.

    In the past 5 years, quality-of-life (QOL) assessment measures such as the McGill, McMaster, Global Visual Analogue Scale, Assessment of QOL at the End of Life, Life Evaluation Questionnaire, and Hospice QOL Index have been devised specifically for patients with advanced cancer. The developers of these instruments have tried to respond to the changing needs of this specific population, taking into account characteristics including poor performance status, difficulty with longitudinal study, rapidly deteriorating physical condition, and change in relevant issues. Emphasis has been placed on patient report, ease and speed of completion, and the existential domain or meaning of life. Novel techniques in QOL measurement have also been adapted for palliative care, such as judgment analysis in the Schedule for the Evaluation of Individual Quality of Life. It is generally agreed that a single tool will not cover all QOL assessment needs.

    2014-07-01

    Full Text Available Despite the fact that most people die in advanced old age, little attention is given to cases involving older people in debates about the moral and legal dimensions of end-of-life decision making. The purpose of this paper is to establish some of the ways our discussions should change as we pay attention to important factors influencing end-of-life decisions for people in advanced old age. Focusing on the prevalence of comorbidities and the likelihood that people in advanced old age will experience an extended period of declining function before death, I argue that our debates should be expanded to include greater consideration of how we want to live in the final stages of life. With this, I am arguing against the tendency to think that “end-of-life” decision making concerns only making decisions about when and how it is appropriate to terminate a person’s life. I argue, further, that we should move away from the medicalization of dying.

    Many studies have drawn attention to deficiencies in the management of major trauma, both in the UK and elsewhere. One area that has received little attention is the documentation of such cases in the Emergency Room. When outcome may be sub-optimal, documentation assumes greater importance if advances are to be made in the organisation of trauma care. Based upon the American College of Surgeons Advanced Trauma Life Support (ATLS) protocols, the authors have designed a document that records dynamically what happens to the multiply injured victim on arrival in the Emergency Room. It unifies the recording of vital signs, whilst acting as an assessment and resuscitation template. By ensuring no life-threatening illness is missed it is likely to improve patient survival. The document can act as a basis for teaching and a medico-legal record, whilst providing the necessary data for quality assurance and outcome audit.

    Many advanced human space exploration missions being considered by the National Aeronautics and Space Administration (NASA) include concepts in which in-space systems cycle between inhabited and uninhabited states. Managing the life support system (LSS) may be particularly challenged during these periods of intermittent dormancy. A study to identify LSS management challenges and considerations relating to dormancy is described. The study seeks to define concepts suitable for addressing intermittent dormancy states and to evaluate whether the reference LSS architectures being considered by the Advanced Exploration Systems (AES) Life Support Systems Project (LSSP) are sufficient to support this operational state. The primary focus of the study is the mission concept considered to be the most challenging-a crewed Mars mission with an extensive surface stay. Results from this study are presented and discussed.

    Quality-of-work-life (QWL) includes broad aspects of the work environment that affect employee learning and health. Canadian health care organizations (HCOs) are being encouraged to monitor QWL, expanding existing occupational health surveillance capacities. To investigate the understanding, collection, diffusion and use of QWL indicators in Canadian HCOs. We obtained cooperation from six diverse public HCOs managing 41 sites. We reviewed documentation relevant to QWL and conducted 58 focus groups/team interviews with strategic, support and programme teams. Group interviews were taped, reviewed and analysed for themes using qualitative data techniques. Indicators were classified by purpose and HCO level. QWL indicators, as such, were relatively new to most HCOs yet the data managed by human resource and occupational health and safety support teams were highly relevant to monitoring of employee well-being (119 of 209 mentioned indicators), e.g. sickness absence. Monitoring of working conditions (62/209) was also important, e.g. indicators of employee workload. Uncommon were indicators of biomechanical and psychosocial hazards at work, despite their being important causes of morbidity among HCO employees. Although imprecision in the definition of QWL indicators, limited links with other HCO performance measures and inadequate HCO resources for implementation were common, most HCOs cited ways in which QWL indicators had influenced planning and evaluation of prevention efforts. Increase in targeted HCO resources, inclusion of other QWL indicators and greater integration with HCO management systems could all improve HCO decision-makers' access to information relevant to employee health.

    Under safeguards agreements that the Government of Canada has with the International Atomic Energy Agency (IAEA), and nuclear cooperation agreements with other states, the Canadian Nuclear Safety Commission (CNSC) is required to track the inventory and movement of all safeguarded material. As safeguards programmes evolve, including the implementation of Integrated Safeguards, the scope of the reporting requirements for facilities within Canada has also increased. At the same time, ensuring the secure transmission of the associated data continues to be an overarching factor. The changes that are occurring in the nuclear material accounting (NMA) landscape have necessitated a modernization of Canada's accounting and reporting system, with the objective of creating a more effective and efficient system, while at the same time maintaining the security of prescribed information. After a review of the environment, the CNSC embarked on a project that would encourage facilities to transition away from traditional modes of NMA reporting and adopt an electronic approach. This paper will discuss how the changes to Canada's NMA infrastructure were identified and implemented internally to allow for optimized electronic reporting. Improvements included the development of the regulatory and guidance documents, the overhaul of the reporting forms, the upgrade of the CNSC's NMA database, and the development of an electronic reporting platform that leveraged existing technologies. The paper will also discuss the logistics of engaging stakeholders throughout the process, launching the system and soliciting feedback for future system improvements. Special consideration will be given to the benefits realized by both the CNSC and facilities who have voluntarily embraced electronic reporting. The final objective of this paper will be to identify the challenges that were faced by the CNSC and the nuclear industry as the system changes were implemented and to highlight how

  10. The fundamental association between mental health and life satisfaction: results from successive waves of a Canadian national survey.

    A self-reported life satisfaction question is routinely used as an indicator of societal well-being. Several studies support that mental illness is an important determinant for life satisfaction and improvement of mental healthcare access therefore could have beneficial effects on a population's life satisfaction. However, only a few studies report the relationship between subjective mental health and life satisfaction. Subjective mental health is a broader concept than the presence or absence of psychopathology. In this study, we examine the strength of the association between a self-reported mental health question and self-reported life satisfaction, taking into account other relevant factors. We conducted this analysis using successive waves of the Canadian Community Health Survey (CCHS) collected between 2003 and 2012. Respondents included more than 400,000 participants aged 12 and over. We extracted information on self-reported mental health, socio-demographic and other factors and examined correlation with self-reported life satisfaction using a proportional ordered logistic regression. Life satisfaction was strongly associated with self-reported mental health, even after simultaneously considering factors such as income, general health, and gender. The poor-self-reported mental health group had a particularly low life satisfaction. In the fair-self-reported mental health category, the odds of having a higher life satisfaction were 2.35 (95% CI 2.21 to 2.50) times higher than the odds in the poor category. In contrast, for the "between 60,000 CAD and 79,999 CAD" household income category, the odds of having a higher life satisfaction were only 1.96 (95% CI 1.90 to 2.01) times higher than the odds in the "less than 19,999 CAD" category. Subjective mental health contributes highly to life satisfaction, being more strongly associated than other selected previously known factors. Future studies could be useful to deepen our understanding of the interplay between

    Advanced life support medications stored in emergency department stretcher areas, diagnostic radiology rooms, and radiotherapy suites are exposed to ionizing radiation. We hypothesized that radiation may decrease the potency and thus the shelf life of medications stored in these areas. Atropine, dopamine, epinephrine, and isoproterenol were exposed to a wide range of ionizing radiation. The potency of the four drugs was unaffected by levels of radiation found in ED stretcher areas and high-volume diagnostic radiograph rooms (eg, chest radiograph, computed tomography, fluoroscopy). The potency of atropine may be reduced by gamma radiation in high-use radiotherapy suites. However, dopamine, epinephrine, and isoproterenol were unaffected by high doses of gamma radiation. Atropine, dopamine, epinephrine, and isoproterenol may be safely kept in ED stretcher areas and diagnostic radiology rooms without loss of potency over the shelf life of the drugs

    To describe the history of the Pediatric Advanced Life Support course and outline the new developments in instructor training that will impact the way debriefing is conducted during Pediatric Advanced Life Support courses. The Pediatric Advanced Life Support course, first released by the American Heart Association in 1988, has seen substantial growth and change over the past few decades. Over that time, Pediatric Advanced Life Support has become the standard for resuscitation training for pediatric healthcare providers in North America. The incorporation of high-fidelity simulation-based learning into the most recent version of Pediatric Advanced Life Support has helped to enhance the realism of scenarios and cases, but has also placed more emphasis on the importance of post scenario debriefing. We developed two new resources: an online debriefing module designed to introduce a new model of debriefing and a debriefing tool for real-time use during Pediatric Advanced Life Support courses, to enhance and standardize the quality of debriefing by Pediatric Advanced Life Support instructors. In this article, we review the history of Pediatric Advanced Life Support and Pediatric Advanced Life Support instructor training and discuss the development and implementation of the new debriefing module and debriefing tool for Pediatric Advanced Life Support instructors. The incorporation of the debriefing module and debriefing tool into the 2011 Pediatric Advanced Life Support instructor materials will help both new and existing Pediatric Advanced Life Support instructors develop and enhance their debriefing skills with the intention of improving the acquisition of knowledge and skills for Pediatric Advanced Life Support students.

    Health in all policies can address chronic disease morbidity and mortality by increasing population-level physical activity and healthy eating, and reducing tobacco and alcohol use. Both governmental and nongovernmental policy influencers are instrumental for health policy that modifies political, economic, and social environments. Policy influencers are informed and persuaded by coalitions that support or oppose changing the status quo. Empirical research examining policy influencers' contact with coalitions, as a social psychological exposure with health policy outcomes, can benefit from application of health communication theories. Accordingly, we analyzed responses to the 2014 Chronic Disease Prevention Survey for 184 Canadian policy influencers employed in provincial governments, municipalities, large workplaces, school boards, and the media. In addition to contact levels with coalitions, respondents' jurisdiction, organization, and ideology were analyzed as potential moderators. Calculating authority score centrality using network analysis, we determined health policy supporters to be more central in policy influencer networks, and theorized their potential to impact health policy public agenda setting via priming and framing processes. We discuss the implications of our results as presenting opportunities to more effectively promote health policy through priming and framing by coordinating coalitions across risk behaviors to advance a societal imperative for chronic disease prevention.

    Living with advanced cancer can present an overwhelming challenge. It may impact the everyday life of the individual with respect to an array of psychological, physical, social, and existential issues. We focus on ways in which people with advanced cancer experience and use their engagement in daily activities when confronting nearing death. Through a phenomenological analysis based on Heidegger's thinking, we illuminate the complexities of "being toward death" and the human striving for authentic being through engagement in daily living. The main findings demonstrate how sensory experiences support being through an appreciation of everyday aesthetics. Furthermore, the making of material things was identified as a means to express the value of self and others in relation to the involved individual's past, present, and future.

    1989-12-01

    Recent studies have concluded that microbial contamination of a nuclear fuel waste disposal vault is inevitable. Factors that will affect the development of substantial population of micro-organisms include: physiological tolerance of microbes; fluid movement in a vault; availability of nutrients; and availability of energy sources. It is difficult to resolve whether microbial growth will either positively or negatively affect the performance of a vault. One of the necessary steps towards ultimately answering this question is to assess the potential for microbial growth in a disposal vault, based on a nutrient and energy budget. This report gives a quantitative (but conservative) inventory of nutrients and potential energy sources present in a Canadian nuclear fuel waste vault, which hypothetically could support the growth of micro-organisms. Maximum population densities are calculated based on these inventories and assuming that all conditions for microbial growth are optimal, although this will certainly not be the case. Laboratory studies under the vault-relevant conditions are being performed to put realistic boundaries on the calculated numbers. Initial results from these studies, combined with data from a natural analogue site indicate that the calculated population densities could be overestimated by four to five orders of magnitude. Limited data show no effect of the presence of microbes on the transport of Tc, I, and Sr in backfill sand columns. Additional work is needed to address transport effects on buffer and backfill clay columns

    As NASA looks beyond the International Space Station toward long-duration, deep space missions away from Earth, the current practice of supplying consumables and spares will not be practical nor affordable. New approaches are sought for life support and habitation systems that will reduce dependency on Earth and increase mission sustainability. To reduce launch mass, further closure of Environmental Control and Life Support Systems (ECLSS) beyond the current capability of the ISS will be required. Areas of particular interest include achieving higher degrees of recycling within Atmosphere Revitalization, Water Recovery and Waste Management Systems. NASA is currently investigating advanced carbon dioxide reduction processes that surpass the level of oxygen recovery available from the Sabatier Carbon Dioxide Reduction Assembly (CRA) on the ISS. Candidate technologies will potentially improve the recovery of oxygen from about 50% (for the CRA) to as much as 100% for technologies who's end product is solid carbon. Improving the efficiency of water recycling and recovery can be achieved by the addition of advanced technologies to recover water from brines and solid wastes. Bioregenerative technologies may be utilized for water reclaimation and also for the production of food. Use of higher plants will simultaneously benefit atmosphere revitalization and water recovery through photosynthesis and transpiration. The level at which bioregenerative technologies are utilized will depend on their comparative requirements for spacecraft resources including mass, power, volume, heat rejection, crew time and reliability. Planetary protection requirements will need to be considered for missions to other solar system bodies.

    The Advanced Integration Matrix (AIM) project at the Johnson Space Center (JSC) was chartered to study and solve systems-level integration issues for exploration missions. One of the first issues identified was an inability to conduct trade studies on control system architectures due to the absence of mature evaluation criteria. Such architectures are necessary to enable integration of regenerative life support systems. A team was formed to address issues concerning software and hardware architectures and system controls.. The team has investigated what is required to integrate controls for the types of non-linear dynamic systems encountered in advanced life support. To this end, a water processing bioreactor testbed is being developed which will enable prototyping and testing of integration strategies and technologies. Although systems such as the water bioreactors exhibit the complexities of interactions between control schemes most vividly, it is apparent that this behavior and its attendant risks will manifest itself among any set of interdependent autonomous control systems. A methodology for developing integration requirements for interdependent and autonomous systems is a goal of this team and this testbed. This paper is a high-level summary of the current status of the investigation, the issues encountered, some tentative conclusions, and the direction expected for further research.

    2007-01-01

    A prospective, descriptive, feasibility study aimed to determine whether an interdisciplinary group of health care experts could design and successfully deliver an international, life support, continuing education program that teaches the medical management of hazardous materials (hazmat) patients. The American Academy of Clinical Toxicology and the University of Arizona College of Medicine, Arizona Emergency Medicine Research Center partnered on July 1, 1998 to develop a two-day Advanced Hazmat Life Support (AHLS) Provider Course. Interdisciplinary expert clinicians designed and then delivered the first AHLS Provider Course in 1999. Prior to this, other courses focused on the management of hazmat incidents and almost exclusively on the prehospital care of hazmat victims by firefighters, hazardous materials technicians, and emergency medical technicians (EMTs), not on the medical management of patients from these incidents. Therefore, AHLS was developed for a broader interdisciplinary group of health care professionals, including both prehospital health care professionals and hospital-based, poison center-based, clinic-based, public health care-based, and other health care professionals. From 1999 through 2006, the AHLS Provider Course has trained 7,142 health care professionals from 48 countries. Of the 7,142 health care professionals worldwide, 43% are paramedics, 24% are physicians, 21% are nurses, 2% are pharmacists, 1% are physician assistants, and 9% are other professionals. Of the professionals trained, 88% are from the United States, 5% from Hong Kong, 2% from Canada, 2% from Australia, 1% from Mexico, and the remainder come from 43 other countries. The Advanced Hazmat Life Support Program is feasible and meets the continuing education needs of health care professionals around the world.(author)

    Determining the most appropriate level of care for patients in the prehospital setting during medical emergencies is essential. A large body of literature suggests that, compared with Basic Life Support (BLS) care, Advanced Life Support (ALS) care is not associated with increased patient survival or decreased mortality. The purpose of this special report is to synthesize the literature to identify common study design and analytic challenges in research studies that examine the effect of ALS, compared to BLS, on patient outcomes. The challenges discussed in this report include: (1) choice of outcome measure; (2) logistic regression modeling of common outcomes; (3) baseline differences between study groups (confounding); (4) inappropriate statistical adjustment; and (5) inclusion of patients who are no longer at risk for the outcome. These challenges may affect the results of studies, and thus, conclusions of studies regarding the effect of level of prehospital care on patient outcomes should require cautious interpretation. Specific alternatives for avoiding these challenges are presented. Li T , Jones CMC , Shah MN , Cushman JT , Jusko TA .

    Incorporating low cost pulses, such as yellow peas, that are rich in nutrients and low in fertilizer requirements, into daily food items, can improve the nutritional and sustainability profile of national diets. This paper systematically characterized the effect of using Canadian grown whole yellow pea and refined wheat flours on nutritional density and carbon footprint in cereal-based food products. Canada-specific production data and the levels of 27 macro- and micronutrients were used to calculate the carbon footprint and nutrient balance score (NBS), respectively, for traditional and reformulated pan bread, breakfast cereal, and pasta. Results showed that partial replacement of refined wheat flour with yellow pea flour increased the NBS of pan bread, breakfast cereal, and pasta by 11%, 70%, and 18%, and decreased the life cycle carbon footprint (kg CO2 eq/kg) by 4%, 11%, and 13%, respectively. The cultivation stage of wheat and yellow peas, and the electricity used during the manufacturing stage of food production, were the hotspots in the life cycle. The nutritional and greenhouse gas (GHG) data were combined as the nutrition carbon footprint score (NCFS) (NBS/g CO2 per serving), a novel indicator that reflects product-level nutritional quality per unit environmental impact. Results showed that yellow pea flour increased the NCFS by 15% for pan bread, 90% for breakfast cereal, and 35% for pasta. The results and framework of this study are relevant for food industry, consumers, as well as global and national policy-makers evaluating the effect of dietary change and food reformulation on nutritional and climate change targets.

    2013-01-01

    Oil sands transportation diversification is important for preventing discounted crude pricing. Current life cycle assessment (LCA) models that assess greenhouse gas (GHG) emissions from crude oil transportation are linearly-scale and fail to account for project specific details. This research sets out to develop a detailed LCA model to compare the energy inputs and GHG emissions of pipeline and rail transportation for oil sands products. The model is applied to several proposed oils sands transportation routes that may serve as future markets. Comparison between transportation projects suggest that energy inputs and GHG emissions show a high degree of variation. For both rail and pipeline transportation, the distance over which the product is transported has a large impact on total emissions. The regional electricity grid and pump efficiency have the largest impact on pipeline emissions, while train engine efficiency and bitumen blending ratios have the largest impact on rail transportation emissions. LCA-based GHG regulations should refine models to account for the range of product pathways and focus efforts on cost-effective emission reductions. As the climate-change impacts of new oil sands transportation projects are considered, GHG emission boundaries should be defined according to operation control. -- Highlights: •A life cycle model is developed to compare transportation of oil sands products. •The model is applied to several potential future oil sands markets. •Energy inputs and GHG emissions are compared. •Model inputs are explored using sensitivity analysis. •Policy recommendations are provided

    The problems of obtaining adequate pure drinking water and disposing of liquid and solid waste in the U.S Arctic, a region where virtually all water is frozen solid for much of the year, has led to unsanitary solutions. Sanitation and a safe water supply are particularly problems in rural villages. These villages are without running water and use plastic buckets for toilets. The outbreak of diseases is believed to be partially attributable to exposure to human waste and lack of sanitation. Villages with the most frequent outbreaks of disease are those in which running water is difficult to obtain. Waste is emptied into open lagoons, rivers, or onto the sea coast. It does not degrade rapidly and in addition to affecting human health, can be harmful to the fragile ecology of the Arctic and the indigenous wildlife and fish populations. Current practices for waste management and sanitation pose serious human hazards as well as threaten the environment. NASA's unique knowledge of water/wastewater treatment systems for extreme environments, identified in the Congressional Office of Technology Assessment report entitled An Alaskan Challenge: Native Villagt Sanitation, may offer practical solutions addressing the issues of safe drinking water and effective sanitation practices in rural villages. NASA's advanced life support technologies are being combined with Arctic science and engineering knowledge to address the unique needs of the remote communities of Alaska through the Advanced Life Systems for Extreme Environments (ALSEE) project. ALSEE is a collaborative effort involving the NASA, the State of Alaska, the University of Alaska, the North Slope Borough of Alaska, Ilisagvik College in Barrow and the National Science Foundation (NSF). The focus is a major issue in the State of Alaska and other areas of the Circumpolar North; the health and welfare of its people, their lives and the subsistence lifestyle in remote communities, economic opportunity, and care for the

    The problems of obtaining adequate pure drinking water and disposing of liquid and solid waste in the U.S. Arctic, a region where virtually all water is frozen solid for much of the year, has led to unsanitary solutions (U.S. Arctic Research Commission). These solutions are also damaging to the environment. Sanitation and a safe water supply are particularly problems in rural villages. About one-fourth of Alaska's 86.000 Native residents live in these communities. They are without running water and use plastic buckets for toilets. The outbreak of diseases is believed to be partially attributable to exposure to human waste. Villages with the most frequent outbreaks of disease are those in which running water is difficult to obtain (Office of Technology Assessment, 1994). Waste is emptied into open lagoons, rivers, or onto the sea coast. It does not degrade rapidly and in addition to affecting human health, can be harmful to the fragile ecology of the Arctic and the indigenous wildlife and fish populations. Advanced Life Systems for Extreme Environments (ALSEE) provides a solution to sanitation and safe water problems. The system uses an advanced integrated technology developed for Antarctic and space applications. ALSEE uses the systems approach to address more than waste and water problems. By incorporating hydroponic horticulture and aquaculture into the waste treatment system, ALSEE addresses the quality and quantity of fresh foods available to Arctic residents. A temperate climate is required for year-round plant growth. ALSEE facilities can be designed to include a climate controlled area within the structure. This type of environment is a change from the long periods of darkness and cold found in the Arctic and can help alleviate stress so often associated with these extremes. While the overall concept of ALSEE projects is advanced, system facilities can be operated by village residents with appropriate training. ALSEE provides continuing training and

    This paper discusses the Portable Life Support Subsystem (PLSS) packaging design work done by the NASA and Hamilton Sundstrand in support of the 3 future space missions; Lunar, Mars and zero-g. The goal is to seek ways to reduce the weight of PLSS packaging, and at the same time, develop a packaging scheme that would make PLSS technology changes less costly than the current packaging methods. This study builds on the results of NASA s in-house 1998 study, which resulted in the "Flex PLSS" concept. For this study the present EMU schematic (low earth orbit) was used so that the work team could concentrate on the packaging. The Flex PLSS packaging is required to: protect, connect, and hold the PLSS and its components together internally and externally while providing access to PLSS components internally for maintenance and for technology change without extensive redesign impact. The goal of this study was two fold: 1. Bring the advanced space suit integrated Flex PLSS concept from its current state of development to a preliminary design level and build a proof of concept mockup of the proposed design, and; 2. "Design" a Design Process, which accommodates both the initial Flex PLSS design and the package modifications, required to accommodate new technology.

    The SENSORS 2000! (S2K!) program at NASA's Ames Research Center is currently developing a biotelemetry system for monitoring pH and temperature in unrestrained subjects. This activity is part of a broader scope effort to provide an Advanced Biotelemetry System (ABTS) for use in future space life sciences research. Many anticipated research endeavors will require biomedical and biochemical sensors and related instrumentation to make continuous inflight measurements in a variable-gravity environment. Since crew time is limited, automated data acquisition, data processing, data storage, and subject health monitoring are required. An automated biochemical and physiological data acquisition system based on non invasive or implantable biotelemetry technology will meet these requirements. The ABTS will ultimately acquire a variety of physiological measurands including temperature, biopotentials (e.g. ECG, EEG, EMG, EOG), blood pressure, flow and dimensions, as well as chemical and biological parameters including pH. Development activities are planned in evolutionary, leveraged steps. Near-term activities include 1) development of a dual channel pH/temperature telemetry system, and 2) development of a low bandwidth, 4-channel telemetry system, that measures temperature, heart rate, pressure, and pH. This abstract describes the pH/temperature telemeter.

    Empirical data suggest that life review is an effective psychospiritual intervention. However, it has not been applied to Chinese patients with advanced cancer, and its effects on this population remain unknown. The aim of the study was to determine the effect of a life review program on quality of life among Chinese patients with advanced cancer. In this prospective randomized controlled trial, a total of 80 patients were randomly assigned to the life review program group and the control group. The 3-weekly life review program included reviewing a life and formulating a life review booklet. Outcome data were assessed by a collector who was blinded to group assignment before and immediately after the program and at a 3-week follow-up. Significantly better scores in overall quality of life, support, negative emotions, sense of alienation, existential distress, and value of life were found in the life review group immediately after the program and at the 3-week follow-up. This study provides additional data on the potential role of a life review in improving quality of life, particularly psychospiritual well being; it also indicates that the life review program could enable Chinese patients with advanced cancer to express their views on life and death. The life review program offers advanced cancer patients an opportunity to integrate their whole life experiences and discuss end-of-life issues, which lays the ground for further active intervention in their psychospiritual distress. The program could be integrated into daily home care to enhance the psychospiritual well-being of Chinese patients with advanced cancer.

  10. Is advanced life support better than basic life support in prehospital care? A systematic review

    Directory of Open Access Journals (Sweden)

    Ryynänen Olli-Pekka

    2010-11-01

    Full Text Available Abstract Background - Prehospital care is classified into ALS- (advanced life support and BLS- (basic life support levels according to the methods used. ALS-level prehospital care uses invasive methods, such as intravenous fluids, medications and intubation. However, the effectiveness of ALS care compared to BLS has been questionable. Aim - The aim of this systematic review is to compare the effectiveness of ALS- and BLS-level prehospital care. Material and methods - In a systematic review, articles where ALS-level prehospital care was compared to BLS-level or any other treatment were included. The outcome variables were mortality or patient's health-related quality of life or patient's capacity to perform daily activities. Results - We identified 46 articles, mostly retrospective observational studies. The results on the effectiveness of ALS in unselected patient cohorts are contradictory. In cardiac arrest, early cardiopulmonary resuscitation and defibrillation are essential for survival, but prehospital ALS interventions have not improved survival. Prehospital thrombolytic treatment reduces mortality in patients having a myocardial infarction. The majority of research into trauma favours BLS in the case of penetrating trauma and also in cases of short distance to a hospital. In patients with severe head injuries, ALS provided by paramedics and intubation without anaesthesia can even be harmful. If the prehospital care is provided by an experienced physician and by a HEMS organisation (Helicopter Emergency Medical Service, ALS interventions may be beneficial for patients with multiple injuries and severe brain injuries. However, the results are contradictory. Conclusions - ALS seems to improve survival in patients with myocardial infarction and BLS seems to be the proper level of care for patients with penetrating injuries. Some studies indicate a beneficial effect of ALS among patients with blunt head injuries or multiple injuries. There is

    To determine whether firefighter/emergency medical technicians-basic (FF/EMT-Bs) staffing basic life support (BLS) ambulances in a two-tiered emergency medical services (EMS) system can safely determine when advanced life support (ALS) is not needed. This was a prospective, observational study conducted in two academic emergency departments (EDs) receiving patients from a large urban fire-based EMS system. Runs were studied to which ALS and BLS ambulances were simultaneously dispatched, with the patient transported by the BLS unit. Prospectively established criteria for potential need for ALS were used to determine whether the FF/EMT-B's decision to cancel the ALS unit was safe, and simple outcomes (admission rate, length of stay, mortality) were examined. In the system studied, BLS crews may cancel responding ALS units at their discretion; there are no protocols or medical criteria for cancellation. A convenience sample of 69 cases was collected. In 52 cases (75%), the BLS providers indicated that they cancelled the responding ALS unit because they did not feel ALS was needed. Of these, 40 (77%) met study criteria for ALS: 39 had potentially serious chief complaints, nine had abnormal vital signs, and ten had physical exam findings that warranted ALS. Forty-five (87%) received an intervention immediately upon ED arrival that could have been provided in the field by an ALS unit, and 16 (31%) were admitted, with a median length of stay of 3.3 days (range 1.1-73.4 days). One patient died. Firefighter/EMT-Bs, working without protocols or medical criteria, cannot always safely determine which patients may require ALS intervention.

    Full Text Available The title of Alice Munro’s Who do you think you are? could just as easily be asked of Canada, without eliciting an easy answer. In ethnic, linguistic, even geographical terms, Canada is hardly homogeneous. Because of this, we can only dream of a unified identity; we are, as Leonard Cohen writes in Beautiful Losers, condemned to “nightmares of identity.” If Canada is too complex for a uniform national identity, one derived from a convenient mythology and distilled into simple symbols, it often seems we have yet to realize it. We long for a mythology, even a modern, and blatantly constructed one. In contemporary Canadian society, ice hockey has filled that symbolic role, serving as a mythology that binds a fragmented people. This paper examines the role of ice hockey as a mythologized symbol of Canadian unity in literature, and questions the appropriateness of that usage.

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

    Consideration is given to the ideas of Oparin and Haldane who independently suggested more than 60 years ago that the first forms of life were anaerobic, heterotrophic bacteria that emerged as the result of a long period of chemical abiotic synthesis of organic compounds. It is suggested that at least some requirements for life are met in the Galaxy due to the cosmic abundance of carbon, nitrogen, oxygen, and other biogenic elements; the existence of extraterrestrial organic compounds; and the processes of stellar and interstellar planetary formation.

    Maintenance of quality of life and symptom management are important in lung cancer therapy. To the author's knowledge, the interplay of respiratory symptoms and sleep disturbance in affecting quality of life in advanced lung cancer remains unexamined. The study was designed to examine the relationships among respiratory symptoms, sleep disturbance, and quality of life in patients with advanced lung cancer. A total of 128 patients with advanced lung cancer (from chest oncology inpatient-units in Shanghai, China) participated in the study. They completed two questionnaires: the Functional Assessment of Cancer Therapy-Lung and the Pittsburgh Sleep Quality Index. Symptomatic breathing difficulty, coughing, shortness of breath, and tightness in the chest were reported in 78.1%, 70.3%, 60.9%, and 60.2% of the patients, respectively. Sleep disturbance affected 62.5% of the patients. The patients with severe respiratory symptoms were more likely to be poor sleepers and to have a lower quality of life. After the covariates were controlled for, regression analysis showed that respiratory symptoms and sleep disturbance were significant indicators of quality of life. In addition, some of the effect of the respiratory symptoms on quality of life was mediated by sleep disturbance. Respiratory symptoms and sleep disturbance were common in the advanced lung cancer patients and had a negative impact on their quality of life; sleep disturbance may mediate the relationship between respiratory symptoms and quality of life.

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

    Most of the studies on the low cycle fatigue life prediction have been reported under isothermal conditions where the deformation of the material is strain dependent. In the development of gas turbines, components such as blades and vanes are exposed to temperature variations in addition to strain cycling. As a result, the deformation process becomes temperature and strain dependent. Therefore, the life of the component becomes sensitive to temperature-strain cycling which produces a process known as {open_quotes}thermomechanical fatigue, or TMF{close_quotes}. The TMF fatigue failure phenomenon has been modeled using conventional fatigue life prediction methods, which are not sufficiently accurate to quantitatively establish an allowable design procedure. To add to the complexity of TMF life prediction, blade and vane substrates are normally coated with aluminide, overlay or thermal barrier type coatings (TBC) where the durability of the component is dominated by the coating/substrate constitutive response and by the fatigue behavior of the coating. A number of issues arise from TMF depending on the type of temperature/strain phase cycle: (1) time-dependent inelastic behavior can significantly affect the stress response. For example, creep relaxation during a tensile or compressive loading at elevated temperatures leads to a progressive increase in the mean stress level under cyclic loading. (2) the mismatch in elastic and thermal expansion properties between the coating and the substrate can lead to significant deviations in the coating stress levels due to changes in the elastic modulii. (3) the {open_quotes}dry{close_quotes} corrosion resistance coatings applied to the substrate may act as primary crack initiation sites. Crack initiation in the coating is a function of the coating composition, its mechanical properties, creep relaxation behavior, thermal strain range and the strain/temperature phase relationship.

    Globular clusters are ancient stellar populations in compact dense ellipsoids. There is no star formation and there are no core-collapse supernovae, but several lines of evidence suggest that globular clusters are rich in planets. If so, and if advanced civilizations can develop there, then the distances between these civilizations and other stars would be far smaller than typical distances between stars in the Galactic disk, facilitating interstellar communication and travel. The potent combination of long-term stability and high stellar densities provides a globular cluster opportunity. Yet the very proximity that promotes interstellar travel also brings danger, as stellar interactions can destroy planetary systems. We find, however, that large portions of many globular clusters are “sweet spots,” where habitable-zone planetary orbits are stable for long times. Globular clusters in our own and other galaxies are, therefore, among the best targets for searches for extraterrestrial intelligence (SETI). We use the Drake equation to compare the likelihood of advanced civilizations in globular clusters to that in the Galactic disk. We also consider free-floating planets, since wide-orbit planets can be ejected to travel through the cluster. Civilizations spawned in globular clusters may be able to establish self-sustaining outposts, reducing the probability that a single catastrophic event will destroy the civilization. Although individual civilizations may follow different evolutionary paths, or even be destroyed, the cluster may continue to host advanced civilizations once a small number have jumped across interstellar space. Civilizations residing in globular clusters could therefore, in a sense, be immortal.

    Advance care planning for end of life typically focuses on the mechanics of completing living wills and durable power of attorney documents. Even when spiritual aspects of end of life care are discussed, the dominant assumptions are those of traditional religious systems. A broad view of spirituality is needed, one that may involve traditional religious beliefs but also includes personal understandings of what is holy or sacred. Embracing this broad practice of spirituality will help both familial and professional caregivers honor an essential aspect of end of life discussions and promote greater discernment of the deep meaning in advance care documents.

    The use of yeasts in controlled ecological life support systems (CELSS) for microbial food regeneration in space required the accurate and reproducible analysis of intracellular carbohydrate and protein levels. The reproducible analysis of glycogen was a key element in estimating overall content of edibles in candidate yeast strains. Typical analytical methods for estimating glycogen in Saccharomyces were not found to be entirely aplicable to other candidate strains. Rigorous cell lysis coupled with acid/base fractionation followed by specific enzymatic glycogen analyses were required to obtain accurate results in two strains of Candida. A profile of edible fractions of these strains was then determined. The suitability of yeasts as food sources in CELSS food production processes is discussed.

    Crop production systems provide bioregenerative technologies to complement human crew life support requirements on long duration space missions. Kennedy Space Center has lead NASA's research on crop production systems that produce high value fresh foods, provide atmospheric regeneration, and perform water processing. As the emphasis on early missions to Mars has developed, our research focused on modular, scalable systems for transit missions, which can be developed into larger autonomous, bioregenerative systems for subsequent surface missions. Components of these scalable systems will include development of efficient light generating or collecting technologies, low mass plant growth chambers, and capability to operate in the high energy background radiation and reduced atmospheric pressures of space. These systems will be integrated with air, water, and thermal subsystems in an operational system. Extensive crop testing has been done for both staple and salad crops, but limited data is available on specific cultivar selection and breadboard testing to meet nominal Mars mission profiles of a 500-600 day surface mission. The recent research emphasis at Kennedy Space Center has shifted from staple crops, such as wheat, soybean and rice, toward short cycle salad crops such as lettuce, onion, radish, tomato, pepper, and strawberry. This paper will review the results of crop experiments to support the Exploration Initiative and the ongoing development of supporting technologies, and give an overview of capabilities of the newly opened Space Life Science (SLS) Lab at Kennedy Space Center. The 9662 square m (104,000 square ft) SLS Lab was built by the State of Florida and supports all NASA research that had been performed in Hanger-L. In addition to NASA research, the SLS Lab houses the Florida Space Research Institute (FSRI), responsible for co-managing the facility, and the University of Florida (UF) has established the Space Agriculture and Biotechnology Research and

    End of life is an unfortunate but inevitable phase of the heart failure patients' journey. It is often preceded by a stage in the progression of heart failure defined as advanced heart failure, and characterised by poor quality of life and frequent hospitalisations. In clinical practice, the efficacy of treatments for advanced heart failure is often assessed by parameters such as clinical status, haemodynamics, neurohormonal status, and echo/MRI indices. From the patients' perspective, however, quality-of-life-related parameters, such as functional capacity, exercise performance, psychological status, and frequency of re-hospitalisations, are more significant. The effects of therapies and interventions on these parameters are, however, underrepresented in clinical trials targeted to assess advanced heart failure treatment efficacy, and data are overall scarce. This is possibly due to a non-universal definition of the quality-of-life-related endpoints, and to the difficult standardisation of the data collection. These uncertainties also lead to difficulties in handling trade-off decisions between quality of life and survival by patients, families and healthcare providers. A panel of 34 experts in the field of cardiology and intensive cardiac care from 21 countries around the world convened for reviewing the existing data on quality-of-life in patients with advanced heart failure, discussing and reaching a consensus on the validity and significance of quality-of-life assessment methods. Gaps in routine care and research, which should be addressed, were identified. Finally, published data on the effects of current i.v. vasoactive therapies such as inotropes, inodilators, and vasodilators on quality-of-life in advanced heart failure patients were analysed.

    Full Text Available The need for integrated methodological framework for sustainability assessment has been widely discussed and is urgent due to increasingly complex environmental system problems. These problems have impacts on ecosystems and human well-being which represent a threat to economic performance of countries and corporations. Integrated assessment crosses issues; spans spatial and temporal scales; looks forward and backward; and incorporates multi-stakeholder inputs. This study aims to develop an integrated methodology by capitalizing the complementary strengths of different methods used by industrial ecologists and biophysical economists. The computational methodology proposed here is systems perspective, integrative, and holistic approach for sustainability assessment which attempts to link basic science and technology to policy formulation. The framework adopts life cycle thinking methods—LCA, LCC, and SLCA; stakeholders analysis supported by multi-criteria decision analysis (MCDA; and dynamic system modelling. Following Pareto principle, the critical sustainability criteria, indicators and metrics (i.e., hotspots can be identified and further modelled using system dynamics or agent based modelling and improved by data envelopment analysis (DEA and sustainability network theory (SNT. The framework is being applied to development of biofuel supply chain networks. The framework can provide new ways of integrating knowledge across the divides between social and natural sciences as well as between critical and problem-solving research.

    In this research, as for light water reactors and fast breeder reactors, for the object of all the processes from the mining, transport and refining of fuel, electric power generation to the treatment and disposal of waste, the amount of energy input and the quantity of CO 2 emission over the life cycle were analyzed, and regarding the influence that the technical progress of nuclear power generation exerted to environment, the effect of improvement was elucidated. Attention has been paid to nuclear power generation as its CO 2 emission is least, and the effect of global warming is smallest. In order to reduce the quantity of radioactive waste generation in LWRs and the cost of fuel cycle, and to extend the operation cycle, the technical development for heightening fuel burnup is in progress. The process of investigation of the new technologies of nuclear power generation taken up in this research is described. The analysis of the energy balance of various power generation methods is discussed. In the case of pluthermal process, the improvement of energy balance ratio is dependent on uranium enrichment technology. Nuclear power generation requires much materials and energy for the construction, and emits CO 2 indirectly. The CO 2 unit emission based on the analysis of energy balance was determined for the new technologies of nuclear power generation, and the results are shown. (K.I.)

    Background Evaluation of the state of health, quality of life, and the relationship between the level of the quality of life and health status in a group of women at an advanced age (90 years of age and older) in Poland. Material/Methods The study was conducted in 2014 in an all-Polish sample of 870 women aged 90 years and older. The research instruments were: the authors’ questionnaire and several standardized tests: Katz Index of Independence in Activities of Daily Living (Katz ADL), Abbreviated Mental Test Score (AMTS), and the World Health Organization Quality of Life (WHOQOL)-BREF. The results of the study were statistically analyzed using significant t-test for mean and regression analysis. Results The majority of women at an advanced age suffered from chronic pain (76%) and major geriatric problems such as hypoacusis (81%), visual disturbances (69%) and urinary incontinence (60%); the minority of women at an advanced age suffered from falls and fainting (39%), stool incontinence (17%), severe functional impairment (24%), and cognitive impairment (10%). On a scale of 1 to 5, women at an advanced age assessed positively for overall quality of life (mean 3.3), social relationships (3.5), and environment (3.2), but negatively for general health, physical health, and psychological health (2.7, 2.7, and 2.8, respectively). The presence of chronic pain and geriatric problems, including urinary and stool incontinences, falls and faint ing, visual disturbances and hypoacusis, significantly decreased overall quality of life; general health, physical health, psychological health, social relationships, and environment. Overall quality of life, general health, physical health, psychological health, social relationships, and environment was correlated with functional and cognitive impairments. Conclusions Quality of life of women at an advanced age decreased if chronic pain, major geriatric problems, or functional or cognitive impairments occurred. PMID:27580565

    Women who seek treatment for pelvic organ prolapse strive for an improvement in quality of life. Body image has been shown to be an important component of differences in quality of life. To date, there are no data on body image in patients with advanced pelvic organ prolapse. Our objective was to compare body image and quality of life in women with advanced pelvic organ prolapse with normal controls. We used a case-control study design. Cases were defined as subjects who presented to a tertiary urogynecology clinic with advanced pelvic organ prolapse (stage 3 or 4). Controls were defined as subjects who presented to a tertiary care gynecology or women's health clinic for an annual visit with normal pelvic floor support (stage 0 or 1) and without urinary incontinence. All patients completed a valid and reliable body image scale and a generalized (Short Form Health Survey) and condition-specific (Pelvic Floor Distress Inventory-20) quality-of-life scale. Linear and logistic regression analyses were performed to adjust for possible confounding variables. Forty-seven case and 51 control subjects were enrolled. After controlling for age, race, parity, previous hysterectomy, and medical comorbidities, subjects with advanced pelvic organ prolapse were more likely to feel self-conscious (adjusted odds ratio 4.7; 95% confidence interval 1.4 to 18, P = .02), less likely to feel physically attractive (adjusted odds ratio 11; 95% confidence interval 2.9 to 51, P body. Subjects with advanced pelvic organ prolapse suffered significantly lower quality of life on the physical scale of the SF-12 (mean 42; 95% confidence interval 39 to 45 versus mean 50; 95% confidence interval 47 to 53, P body image correlated with lower quality of life on both the physical and mental scales of the SF-12 as well as the prolapse, urinary, and colorectal scales and overall summary score of Pelvic Floor Distress Inventory-20 in subjects with advanced pelvic organ prolapse.

    Understanding end of life preferences amongst the oldest old is crucial to informing appropriate palliative and end of life care internationally. However, little has been reported in the academic literature about the end of life preferences of people in advanced age, particularly the preferences of indigenous older people, including New Zealand Māori. Data on end of life preferences were gathered from 147 Māori (aged >80 years) and 291 non- Māori aged (>85 years), during three waves of Te Puawaitangi O Nga Tapuwae Kia Ora Tonu, Life and Living in Advanced Age (LiLACs NZ). An interviewer-led questionnaire using standardised tools and including Māori specific subsections was used. The top priority for both Māori and non-Māori participants at end of life was 'not being a burden to my family'. Interestingly, a home death was not a high priority for either group. End of life preferences differed by gender, however these differences were culturally contingent. More female Māori participants wanted spiritual practices at end of life than male Māori participants. More male non-Māori participants wanted to be resuscitated than female non- Māori participants. That a home death was not in the top three end of life priorities for our participants is not consistent with palliative care policy in most developed countries where place of death, and particularly home death, is a central concern. Conversely our participants' top concern - namely not being a burden - has received little research or policy attention. Our results also indicate a need to pay attention to diversity in end of life preferences amongst people of advanced age, as well as the socio-cultural context within which preferences are formulated.

    Purpose MA.17R was a Canadian Cancer Trials Group-led phase III randomized controlled trial comparing letrozole to placebo after 5 years of aromatase inhibitor as adjuvant therapy for hormone receptor-positive breast cancer. Quality of life (QOL) was a secondary outcome measure of the study, and here, we report the results of these analyses. Methods QOL was measured using the Short Form-36 (SF-36; two summary scores and eight domains) and menopause-specific QOL (MENQOL; four symptom domains) at baseline and every 12 months up to 60 months. QOL assessment was mandatory for Canadian Cancer Trials Group centers but optional for centers in other groups. Mean change scores from baseline were calculated. Results One thousand nine hundred eighteen women were randomly assigned, and 1,428 women completed the baseline QOL assessment. Compliance with QOL measures was > 85%. Baseline summary scores for the SF-36 physical component summary (47.5 for letrozole and 47.9 for placebo) and mental component summary (55.5 for letrozole and 54.8 for placebo) were close to the population norms of 50. No differences were seen between groups in mean change scores for the SF-36 physical and mental component summaries and the other eight QOL domains except for the role-physical subscale. No difference was found in any of the four domains of the MENQOL Conclusion No clinically significant differences were seen in overall QOL measured by the SF-36 summary measures and MENQOL between the letrozole and placebo groups. The data indicate that continuation of aromatase inhibitor therapy after 5 years of prior treatment in the trial population was not associated with a deterioration of overall QOL.

    Jaksa, Peter J; Mahoney, James L

    2010-12-01

    The purpose of this study was to evaluate and validate the Cardiff Wound Impact Schedule (CWIS), a disease-specific quality-of-life measure, in a diabetic foot ulcer (DFU) population. Patients with DFUs have restrictions as part of their treatment and rehabilitation, which can affect health-related quality of life (HRQoL). Because of the high number of comorbidities experienced in diabetes, a disease-specific quality-of-life measure is needed to best assess the affect of a foot ulcer on HRQoL. Patients with DFUs completed the CWIS and a World Health Organization generic quality-of-life questionnaire. Validity was assessed by comparing domains of the questionnaires. Patients were categorised using the University of Texas wound classification system. Mean CWIS scores were compared between categories to assess the questionnaire's ability to differentiate wound severity. Patients with open ulcers scored significantly lower on the CWIS than those with healed ulcers. Correlations between questionnaire domains were as follows: Social Life with Social Functioning (r = 0·641, P Health (r = 0·533, P Health-Related Quality of Life with Vitality (r = 0·425, P < 0·01). However, there was no significant difference in mean CWIS scores between categories of wound severity. We have demonstrated the ability of the CWIS in assessing HRQoL in a DFU population and its ability to differentiate between healed and non healed states. © 2010 The Authors.

    A life extension program has been developed for the US Department of Energy's Advanced Test Reactor. The program is an adaptation of life extension pilot programs at the Surry Unit 1 and Monticello generating stations and is being completed in three phases. In Phase 1, the critical plant components were identified. In Phase 2, existing lifetime analyses and support data for the critical components were reviewed. The results from the review give a preliminary indication that an overall plant lifetime in excess of forty years is feasible. In Phase 3, now in progress, detailed evaluations for component life extensions are being performed. 2 refs., 2 figs., 1 tab

    This study aimed to investigate the quality of life of parents of a child with autism spectrum disorder in Quebec. Seventy-seven participants completed a questionnaire with socio-biographic information and five self-assessed scales, to measure perceived stress, social support and control, coping strategies, and quality of life. Perception of their child's autonomy level, of the severity of the disorder, of the family's income, as well as changes in their professional or familial organization influenced parents' quality of life. Perceiving their situation as a threat predicted poor quality of life, whereas satisfaction of social support predicted good quality of life. In addition, parents who used problem solving and support-seeking coping strategies had a better relationship with their child, whereas those who used more emotion-centered coping strategies struggled. Lastly, parents who felt they had the power to contribute to their child's development were more satisfied and less disturbed. Beyond the parents' actual situation, our results underscore the importance of paying attention to their own perception of the situation in order to provide them with appropriate support.

    Full Text Available Eleven advanced strawberry lines (‘SJ011‑10’, ‘SJ0440‑2’, ‘SJ061‑8’, ‘SJ066‑3’, ‘SJ069‑3’, ‘SJ069‑12’, ‘SJ0814‑37’, ‘SJ8518‑11’, ‘K04‑12’, ‘LL0220‑10’ and ‘V151’ were evaluated for their yield, fruit quality, total phenolic content, total antioxidant capacity, and phenolic composition, and were compared with a commercial cultivar (‘Wendy’. The results showed that ‘SJ069‑3’ had excellent soluble solids content, mid-level titratable acidity, low weight loss, and the best firmness among all the cultivars. Higher total antioxidant capacity was found in ‘SJ069‑3’, according to ferric reducing antioxidant power and oxygen radical absorbance capacity assays, an indication that ‘SJ069‑3’ is a promising new cultivar for the fresh market. In addition to rich individual phenolics, ‘SJ061‑8’ had the highest total antioxidant capacity, which was significantly different from the other genotypes, suggesting the potential use of this line as parent material in breeding or as a functional food ingredient. There was a strong relationship between total antioxidant capacity and total phenolic content, according to Folin–Ciocalteu, ferric reducing antioxidant power, and oxygen radical absorbance capacity assays. This study confirms that anthocyanins are major phenolic compounds contributing to the main antioxidant power of strawberries.

    The burden of advanced COPD is high globally; however, little is known about how often end of life strategies are used by this population. To describe trends in the use of end of life care strategies by people with advanced COPD in Ontario, Canada. A population-based repeated cross-sectional study examining end of life care strategies in individuals with advanced COPD was conducted. Annual proportions of individuals who received formal palliative care, long-term oxygen therapy or opioids from 2004 to 2014 were determined. Results were age- and sex- standardized as well as stratified by age, sex, socioeconomic status, urban/rural residence and immigrant status. Measurement/Main Results: There were 151,912 persons with advanced COPD in Ontario between 2004 and 2014. Use of formal palliative care services increased 1% per year from 5.3% in 2004 to 14.3% in 2014 (p value for trend COPD using end of life strategies, although increasing, remains low. Efforts should focus on increasing access to such strategies as well as educating patients and providers of their benefits.

    1998-01-01

    An overview of the daily production from the Western Canada Sedimentary Basin (WCSB) from 1986 to 1997 was presented. This presentation also outlined Canadian production trends, Canadian reserves and resources, and supply challenges. Ultimate conventional marketable gas from the WCSB, the Scotian Shelf, the Beaufort Sea and Canada's Arctic region was estimated at 591 TCF. Issues regarding supply and demand of natural gas such as the impact of electricity restructuring on pricing, generation fuel mix, the capacity of the U.S. market to absorb Canadian heavy oil production, and the influence of the rate of technological advances on supply and demand were outlined. The overall conclusion confirmed the health and competitiveness of the Canadian upstream sector and expressed confidence that the WCSB can support rising levels of production to meet the expected continued market growth. tabs., figs

    2013-03-01

    Full Text Available Management of the multiply injured patient requires a co-ordinated multi-disciplinary approach in order to optimise patients’ outcome. A working knowledge of the sort of problems these patients encounter is therefore vital to ensure that life-threatening injuries are recognised and treated in a timely pattern and that more minor associated injuries are not omitted. This article outlines the management of polytraumatized patients using the Advanced Trauma Life Support (ATLS principles and highlights the areas of specific involvement of the engaged medical team. Advanced Trauma Life Support is generally regarded as the gold standard and is founded on a number of well known principles, but strict adherence to protocols may have its drawbacks when facial trauma co-exists. These can arise in the presence of either major or minor facial injuries, and oral and maxillofacial surgeons need to be aware of the potential problems.

    As one of the non-water coolant Small-Modular Reactor (SMR) core concepts for use in the mid- to long-term, ANL has proposed a 100 MWe Advanced sodium-cooled Fast Reactor core concept (AFR-100) targeting a small grid, transportable from pre-licensed factories to the remote plant site for affordable supply. Various breed-and-burn core concepts have been proposed to extend the reactor cycle length, which includes CANDLE with a cigar-type depletion strategy, TerraPower reactors with fuel shuffling for effective breeding, et al. UNIST has also proposed an ultra-long cycle fast reactor (UCFR) core concept having the power rating of 1000 MWe. By adopting the breed-and-burn strategies, the UCFR core can maintain criticality for a targeting reactor lifetime of 60 years without refueling. The objective of this project is to develop an advanced long-life SMR core concept by adopting both the small modular design features of the AFR-100 and the long-life breed-and-burn concept of the UCFR. A conceptual design of long life small modular fast reactor is under development by adopting both the small modular design features of the AFR-100 and the long-life breed-and-burn concept of the UCFR. The feasibility of the long-life fast reactor concepts was reviewed to obtain the core design guidelines and the reactor design requirements of long life small modular fast reactor were proposed in this study.

    2017-06-01

    Despite the emerging presence of South Asian elderly population in Canada, there continues to be a paucity of research concerning the immigration and acculturation experiences of these marginalized elderly populations and their quality of life. This research builds knowledge of the quality of life experiences faced by South Asian elderly immigrant women residing in Canada using an intersectional analytical framework. While there is a gradually developing body of research regarding elder persons globally, the present research is unique in that explores challenges, stresses and strains, and builds an understanding of the treatment of older ethnic minorities and immigrant families. Furthermore, this research has implications for policies and practices governing these growing aging populations. Finally, this research gives voice to a "silenced" and invisible group of elders whose stories may help to make improvements in the quality of living and well-being for the aging South Asian immigrant population in Canada.

    Consumers and organizations worldwide are searching for low-carbon alternatives to conventional gasoline and diesel vehicles to reduce greenhouse gas (GHG) emissions and their impact on the environment. A comprehensive technique used to estimate overall cost and environmental impact of vehicles is known as life cycle assessment (LCA). In this article, a comparative LCA of diesel and compressed natural gas (CNG) powered heavy duty refuse collection vehicles (RCVs) is conducted. The analysis utilizes real-time operational data obtained from the City of Surrey in British Columbia, Canada. The impact of the two alternative vehicles is assessed from various points in their life. No net gain in energy use is found when a diesel powered RCV is replaced by a CNG powered RCV. However, significant reductions (approximately 24% CO 2 -equivalent) in GHG and criteria air contaminant (CAC) emissions are obtained. Moreover, fuel cost estimations based on 2011 price levels and a 5-year lifetime for both RCVs reveal that considerable cost savings may be achieved by switching to CNG vehicles. Thus, CNG RCVs are not only favorable in terms of reduced climate change impact but also cost effective compared to conventional diesel RCVs, and provide a viable and realistic near-term strategy for cities and municipalities to reduce GHG emissions. - Highlights: ► Life cycle analysis is performed on two alternative refuse collection vehicle technologies. ► Real-time operational data obtained by the City of Surrey in British Columbia are utilized. ► The life cycle energy use is similar for diesel and CNG RCVs. ► A 24% reduction of GHG emissions (CO 2 -equivalent) may be realized by switching from diesel to CNG. ► CNG RCVs are estimated to be cost effective and may lead to reduced fuel costs.

    Fostering quality work life is paramount to building a strong patient safety culture in healthcare organizations. Data from two patient safety culture and work-life questionnaires used for Accreditation Canada's national program were analyzed. Strong team leadership was reported in that units were doing a good job of identifying, assessing and managing risks to patients. Seventy-one percent of respondents gave their unit a positive overall grade on patient safety, and 79% of respondents felt that they could often do their best-quality work in their job. However, healthcare workers felt that they did not have enough time to do their jobs adequately and indicated that co-workers were cutting corners in patient care in order to save time. This article discusses engaging both senior leadership and the entire organization in the change process, ensuring supervisory support, and using performance measures to focus organizational efforts on key priorities all as improvement strategies relevant to these findings. These strategies can be used by organizations across sectors and jurisdictions and by healthcare leaders to positively affect work life and patient safety.

    There's great excitement about life prospects on icy fluid-containing moons orbiting our Solar System's gas giant planets, newly discovered planet candidates and continuing long-term interest in possible Mars life. The astrobiology/planetary research communities require advanced technologies to explore and study both Solar System bodies and exoplanets for evidence of life. The Tricorder Workshop, held at Ames Research Center May 19-20, 2017, explored technology topics focused on non-invasive or minimally invasive methods for life detection. The workshop goal was to tease out promising ideas for low TRL concepts for advanced life detection technologies that could be applied to the surface and near-subsurface of Mars and Ocean Worlds (such as Europa and Enceladus) dominated by icy terrain. The workshop technology focus centered on mid-to-far term instrument concepts or other enabling technologies (e.g. robotics, machine learning, etc.) primarily for landed missions, which could detect evidence of extant, extinct and/or "weird" life including the notion of "universal biosignatures". Emphasis was placed on simultaneous and serial sample measurements using a suite of instruments and technological approaches with planetary protection in mind. A follow-on workshop, held July 24 at Caltech, sought to develop a generic flowchart of in situ observations and measurements to provide sufficient information to determine if extant life is present in an environment. The process didn't require participant agreement as to definition of extant life, but instead developed agreement on necessary observations and instruments. The flowchart of measurements was designed to maximize the number of simultaneous observations on a single sample where possible, serializing where necessary, and finally dividing it into parts for the most destructive analyses at the end. Selected concepts from the workshops outlined in this poster provide those technology areas necessary to solicit and develop

  6. Advanced aircraft service life monitoring method via flight-by-flight load spectra

    Science.gov (United States)

    Lee, Hongchul

    This research is an effort to understand current method and to propose an advanced method for Damage Tolerance Analysis (DTA) for the purpose of monitoring the aircraft service life. As one of tasks in the DTA, the current indirect Individual Aircraft Tracking (IAT) method for the F-16C/D Block 32 does not properly represent changes in flight usage severity affecting structural fatigue life. Therefore, an advanced aircraft service life monitoring method based on flight-by-flight load spectra is proposed and recommended for IAT program to track consumed fatigue life as an alternative to the current method which is based on the crack severity index (CSI) value. Damage Tolerance is one of aircraft design philosophies to ensure that aging aircrafts satisfy structural reliability in terms of fatigue failures throughout their service periods. IAT program, one of the most important tasks of DTA, is able to track potential structural crack growth at critical areas in the major airframe structural components of individual aircraft. The F-16C/D aircraft is equipped with a flight data recorder to monitor flight usage and provide the data to support structural load analysis. However, limited memory of flight data recorder allows user to monitor individual aircraft fatigue usage in terms of only the vertical inertia (NzW) data for calculating Crack Severity Index (CSI) value which defines the relative maneuver severity. Current IAT method for the F-16C/D Block 32 based on CSI value calculated from NzW is shown to be not accurate enough to monitor individual aircraft fatigue usage due to several problems. The proposed advanced aircraft service life monitoring method based on flight-by-flight load spectra is recommended as an improved method for the F-16C/D Block 32 aircraft. Flight-by-flight load spectra was generated from downloaded Crash Survival Flight Data Recorder (CSFDR) data by calculating loads for each time hack in selected flight data utilizing loads equations.

    Full Text Available Research and technology developments surrounding Advanced Life-Support (ALS began at the University of Guelph in 1992 as the Space and Advanced Life Support Agriculture (SALSA program, which now represents Canada’s primary contribution to ALS research. The early focus was on recycling hydroponic nutrient solutions, atmospheric gas analysis and carbon balance, sensor research and development, inner/intra-canopy lighting and biological filtration of air in closed systems. With funding from federal, provincial and industry partners, a new generation of technology emerged to address the challenges of deploying biological systems as fundamental components of life-support infrastructure for long-duration human space exploration. Accompanying these advances were a wide range of technology transfer opportunities in the agri-food and health sectors, including air and water remediation, plant and environment sensors, disinfection technologies, recyclable growth substrates and advanced light emitting diode (LED lighting systems. This report traces the evolution of the SALSA program and catalogues the benefits of ALS research for terrestrial and non-terrestrial applications.

    2008-12-01

    We used Life Cycle Assessment to scenario model the potential reductions in cumulative energy demand (both fossil and renewable) and global warming, acidifying, and ozone-depleting emissions associated with a hypothetical national transition from conventional to organic production of four major field crops [canola (Brassica rapa), corn (Zea mays), soy (Glycine max), and wheat (Triticum aestivum)] in Canada. Models of these systems were constructed using a combination of census data, published values, and the requirements for organic production described in the Canadian National Organic Standards in order to be broadly representative of the similarities and differences that characterize these disparate production technologies. Our results indicate that organic crop production would consume, on average, 39% as much energy and generate 77% of the global warming emissions, 17% of the ozone-depleting emissions, and 96% of the acidifying emissions associated with current national production of these crops. These differences were almost exclusively due to the differences in fertilizers used in conventional and organic farming and were most strongly influenced by the higher cumulative energy demand and emissions associated with producing conventional nitrogen fertilizers compared to the green manure production used for biological nitrogen fixation in organic agriculture. Overall, we estimate that a total transition to organic production of these crops in Canada would reduce national energy consumption by 0.8%, global warming emissions by 0.6%, and acidifying emissions by 1.0% but have a negligible influence on reducing ozone-depleting emissions.

    People with advanced cancer are able to live for extended periods of time. Advanced cancer can cause functional limitations influencing the ability to manage occupations. Although studies have shown that people with advanced cancer experience occupational difficulties, there is only limited research that specifically explores how these occupational difficulties are managed. To describe and explore how people with advanced cancer manage occupations when living at home. A sub-sample of 73 participants from a larger occupational therapy project took part in the study. The participants were consecutively recruited from a Danish university hospital. Qualitative interviews were performed at the homes of the participants. Content analysis was applied to the data. Managing occupations were manifested in two main categories; (1) Conditions influencing occupations in everyday life and (2) Self-developed strategies to manage occupations. The findings suggest that people with advanced cancer should be supported to a greater extent in finding ways to manage familiar as well as new and more personally meaningful occupations to enhance quality of life.

  10. Organ donation after medical assistance in dying or cessation of life-sustaining treatment requested by conscious patients: the Canadian context.

    Science.gov (United States)

    Allard, Julie; Fortin, Marie-Chantal

    2017-09-01

    In June 2016, following the decision of the Supreme Court of Canada to decriminalise assistance in dying, the Canadian government enacted Bill C-14, legalising medical assistance in dying (MAID). In 2014, the province of Quebec had passed end-of-life care legislation making MAID available as of December 2015. The availability of MAID has many implications, including the possibility of combining this practice with organ donation through the controlled donation after cardiac death (cDCD) protocol. cDCD most often occurs in cases where the patient has a severe neurological injury but does not meet all the criteria for brain death. The donation is subsequent to the decision to withdraw life-sustaining treatment (LST). Cases where patients are conscious prior to the withdrawal of LST are unusual, and have raised doubts as to the acceptability of removing organs from individuals who are not neurologically impaired and who have voluntarily chosen to die. These cases can be compared with likely scenarios in which patients will request both MAID and organ donation. In both instances, patients will be conscious and competent. Organ donation in such contexts raises ethical issues regarding respect for autonomy, societal pressure, conscientious objections and the dead-donor rule. In this article, we look at relevant policies in other countries and examine the ethical issues associated with cDCD in conscious patients who choose to die.

    People with cancer face complex medical decisions, including whether to receive life-sustaining treatments at the end of life. It is not unusual for clinicians to make assumptions about patients' wishes based on whether they had previously chosen to pursue curative treatment. We hypothesized that cancer patients who initially underwent curative intent surgery (CIS) would prefer more aggressive end-of-life treatments compared to patients whose treatment was noncurative intent (non-CIT). This study was a retrospective review of data from a large, randomized controlled trial examining the use of an online decision aid for advance care planning, "Making Your Wishes Known" (MYWK), with patients who had advanced cancer. We reviewed patients' medical records to determine which patients underwent CIS versus non-CIT. In the parent trial, conducted at an academic medical center (2007-2012), 200 patients were enrolled with stage IV malignancy or other poor prognosis cancer. Patients' preferences for aggressive treatment were measured in two ways: using patient-selected General Wishes statements generated by the decision aid and patient-selected wishes for specific treatments under various hypothetical clinical scenarios (Specific Wishes). We evaluated 79 patients. Of these, 48 had undergone initial CIS and 31 had non-CIT. Cancer patients who initially underwent CIS did not prefer more aggressive end-of-life treatments compared to patients whose treatment was non-CIT. Clinicians should avoid assumptions about patients' preferences for life-sustaining treatment based on their prior choices for aggressive treatment.

    Full Text Available Significant progress is being made in the development of the next generation of low cost life detection instrumentation with much smaller size, mass and energy requirements. Here, we describe in situ life detection and sequencing in the field in soils over laying ice wedges in polygonal permafrost terrain on Axel Heiberg Island, located in the Canadian high Arctic (79°26′N, an analog to the polygonal permafrost terrain observed on Mars. The life detection methods used here include (1 the cryo-iPlate for culturing microorganisms using diffusion of in situ nutrients into semi-solid media (2 a Microbial Activity Microassay (MAM plate (BIOLOG Ecoplate for detecting viable extant microorganisms through a colourimetric assay, and (3 the Oxford Nanopore MinION for nucleic acid detection and sequencing of environmental samples and the products of MAM plate and cryo-iPlate. We obtained 39 microbial isolates using the cryo-iPlate, which included several putatively novel strains based on the 16S rRNA gene, including a Pedobacter sp. (96% closest similarity in GenBank which we partially genome sequenced using the MinION. The MAM plate successfully identified an active community capable of L-serine metabolism, which was used for metagenomic sequencing with the MinION to identify the active and enriched community. A metagenome on environmental ice wedge soil samples was completed, with base calling and uplink/downlink carried out via satellite internet. Validation of MinION sequencing using the Illumina MiSeq platform was consistent with the results obtained with the MinION. The instrumentation and technology utilized here is pre-existing, low cost, low mass, low volume, and offers the prospect of equipping micro-rovers and micro-penetrators with aggressive astrobiological capabilities. Since potentially habitable astrobiology targets have been identified (RSLs on Mars, near subsurface water ice on Mars, the plumes and oceans of Europa and Enceladus

    Japanese citizens are interested in choosing their own end-of-life care, but few have created their own advance directive. This study examined changes among Japanese citizens' attitudes toward end-of-life care and advance directives and explored factors that affected these attitudes. We conducted five focus groups with 48 participants in 2009 and 2010. All participants were members of health cooperatives in Tokyo. We identified many barriers and reasons for creating and writing down advance directives. Experience caring for dying people and having a serious disease affected attitudes toward advance directives. Some participants changed their attitude toward end-of-life care by writing their own advance directive. When someone is writing advance directives, asking about his/her past experience of caring may be helpful. And learning about or filling out advance directives may help to break down resistance to using these documents.

    The objective of this study was to examine the source of advanced cancer patients' information about their prognosis and determine whether this source of information could explain racial disparities in the accuracy of patients' life expectancy estimates (LEEs). Coping With Cancer was a prospective, longitudinal, multisite study of terminally ill cancer patients followed until death. In structured interviews, patients reported their LEEs and the sources of these estimates (ie, medical providers, personal beliefs, religious beliefs, and other). The accuracy of LEEs was calculated through a comparison of patients' self-reported LEEs with their actual survival. The sample for this analysis included 229 patients: 31 black patients and 198 white patients. Only 39.30% of the patients estimated their life expectancy within 12 months of their actual survival. Black patients were more likely to have an inaccurate LEE than white patients. A minority of the sample (18.3%) reported that a medical provider was the source of their LEEs; none of the black patients (0%) based their LEEs on a medical provider. Black race remained a significant predictor of an inaccurate LEE, even after the analysis had been controlled for sociodemographic characteristics and the source of LEEs. The majority of advanced cancer patients have an inaccurate understanding of their life expectancy. Black patients with advanced cancer are more likely to have an inaccurate LEE than white patients. Medical providers are not the source of information for LEEs for most advanced cancer patients and especially for black patients. The source of LEEs does not explain racial differences in LEE accuracy. Additional research into the mechanisms underlying racial differences in prognostic understanding is needed.

    The quality of life is affected frequently observed in women with advanced breast cancer and is considered a leading indicator of effectiveness of palliative care. A descriptive, quasi-experimental study is presented ex-ante / ex-post, by applying open-ended interviews to explore the effects on the processes of adaptation of each patient and a self-administrable scale identified specific dimensions of quality of life, satisfaction with care and overall quality of life. The intervention was performed palliative home care to 52 women, according to the damages identified in the baseline diagnosis. The overall strategy included four steps: clinical and socio-demographic characterization of women; identification of the effects on the processes of adaptation by the theoretical model of Roy and dimensions of quality of life frequently affected, to design individually oriented actions on the drive shaft of Nursing Interventions Classification and evaluation of results intervention. The dimensions achieved higher frequency of involvement were: behavior, physical symptoms, pain interference and leisure activities, social life and family. Data were analyzed with qualitative methodologies and uni and multivariate statistical processing. After the intervention favorable changes in adaptive processes and dimensions of quality of life were observed; well as in the assessment of overall satisfaction with life. It was interesting that the dimensions of satisfaction assessed at the end of the intervention obtained an unfavorable assessment, outcome associated with sociodemographic variables. (author)

    Anesthesia management and advanced life support for the severely wounded personnel at military medical evacuation levels in armed conflict (local war) is time-consuming and resource-requiring task. One of the mathematical modeling methods was used to evaluate capabilities of anesthesia and intensive care units at tactical level. Obtained result allows us to tell that there is a need to make several system changes of the existing system of anesthesia management and advanced life support for the severely wounded personnel at military medical evacuation levels. In addition to increasing number of staff of anesthesiology-critical care during the given period of time another solution should be the creation of an early evacuation to a specialized medical care level by special means while conducting intensive monitoring and treatment.

    Edible oil is a critical component of the proposed plant-based Advanced Life Support (ALS) diet. Soybean, peanut, and single-cell oil are the oil source options to date. In terrestrial manufacture, oil is ordinarily extracted with hexane, an organic solvent. However, exposed solvents are not permitted in the spacecraft environment or in enclosed human tests by National Aeronautics and Space Administration due to their potential danger and handling difficulty. As a result, alternative oil-processing methods will need to be utilized. Preparation and recovery options include traditional dehulling, crushing, conditioning, and flaking, extrusion, pressing, water extraction, and supercritical extraction. These processing options were evaluated on criteria appropriate to the Advanced Life Support System and BIO-Plex application including: product quality, product stability, waste production, risk, energy needs, labor requirements, utilization of nonrenewable resources, usefulness of by-products, and versatility and mass of equipment to determine the most appropriate ALS edible oil-processing operation.

    To determine whether consumption of whole-grain rye bread, oatmeal, and whole-wheat bread, during different periods of life, is associated with risk of prostate cancer (PCa). From 2002 to 2006, 2,268 men, aged 67-96 years, reported their dietary habits in the AGES-Reykjavik cohort study. Dietary habits were assessed for early life, midlife, and current life using a validated food frequency questionnaire. Through linkage to cancer and mortality registers, we retrieved information on PCa diagnosis and mortality through 2009. We used regression models to estimate odds ratios (ORs) and hazard ratios (HRs) for PCa according to whole-grain consumption, adjusted for possible confounding factors including fish, fish liver oil, meat, and milk intake. Of the 2,268 men, 347 had or were diagnosed with PCa during follow-up, 63 with advanced disease (stage 3+ or died of PCa). Daily rye bread consumption in adolescence (vs. less than daily) was associated with a decreased risk of PCa diagnosis (OR = 0.76, 95 % confidence interval (CI): 0.59-0.98) and of advanced PCa (OR = 0.47, 95 % CI: 0.27-0.84). High intake of oatmeal in adolescence (≥5 vs. ≤4 times/week) was not significantly associated with risk of PCa diagnosis (OR = 0.99, 95 % CI: 0.77-1.27) nor advanced PCa (OR = 0.67, 95 % CI: 0.37-1.20). Midlife and late life consumption of rye bread, oatmeal, or whole-wheat bread was not associated with PCa risk. Our results suggest that rye bread consumption in adolescence may be associated with reduced risk of PCa, particularly advanced disease.

    Quality of life (QOL) is the main outcome measure for patients with advanced cancer at the end of life. The McGill Quality of Life Questionnaire (MQOL) is designed specifically for palliative care patients and has been translated and validated in Hong Kong and Taiwan. This study aimed to investigate the QOL of patients with advanced cancer using the MQOL-Taiwan version after cultural adaptation to the Chinese mainland. A cross-sectional survey design was used. QOL data from patients with advanced cancer were gathered from 13 hospitals including five tertiary hospitals, six secondary hospitals, and community health care service centers in Shanghai and analyzed. QOL was assessed using the MQOL-Chinese version. Statistical analyses were performed using descriptive statistics, multiple regression analysis, and Spearman rank correlation analysis. A total of 531 cancer patients (297 male and 234 female) in 13 hospitals were recruited into the study and administered the MQOL-Chinese. The score of the support subscale was highest (6.82), and the score of the existential well-being subscale was the lowest (4.65). The five physical symptoms most frequently listed on the MQOL-Chinese were pain, loss of appetite, fatigue, powerless, and dyspnea. Participants' sex, educational level, number of children, disclosure of the disease, and hospital size were associated with their overall QOL. The Spearman rank correlation analysis found that Karnofsky Performance Status scores correlated with the MQOL-Chinese single-item score, physical well-being, psychological well-being, existential well-being, and support domains (P patients with advanced cancer. The association between the characteristics of patients, Karnofsky Performance Status, and their QOL also was identified. Copyright © 2014 American Academy of Hospice and Palliative Medicine.

    Full Text Available The methodology of life-cycle assessment was applied in order to evaluate the environmental performance of a hypothetical Saskatchewan lignite-fueled Integrated Gasification Combined Cycle (IGCC electricity generation, with and without pre-combustion carbon dioxide (CO2 capture from a full life-cycle perspective. The emphasis here is placed on environmental performance associated with air contaminants of the comparison between IGCC systems (with and without CO2 capture and a competing lignite pulverized coal-fired electricity generating station in order to reveal which technology offers the most positive environmental effects. Moreover, ambient air pollutant modeling was also conducted by using American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD air dispersion modeling to determine the ground-level concentration of pollutants emitted from four different electricity generating stations. This study assumes that all stations are located close to Estevan. The results showed a significant reduction in greenhouse gas (GHG emissions and acidification potential by applying both post-combustion and pre-combustion CO2 capture processes. The GHG emissions were found to have reduced by 27%–86%, and IGCC systems were found to compare favorably to pulverized coal systems. However, in other environmental impact categories, there are multiple environmental trade-offs depending on the capture technology used. In the case of post-combustion capture, it was observed that the environmental impact category of eutrophication potential, summer smog, and ozone depletion increased due to the application of the CO2 capture process and the surface mining coal operation. IGCC systems, on the other hand, showed the same tendency as the conventional coal-fired electricity generation systems, but to a lesser degree. This is because the IGCC system is a cleaner technology that produces lower pollutant emission levels than the electricity

    The recently developed Canadian Health Care Evaluation Project (CANHELP) questionnaire, which can be used to assess both patient and family satisfaction with end-of-life care, takes 40-60 minutes to complete. The length of the interview may limit its uptake and clinical utility; a shorter version would make its use more feasible. The purpose of this study was to develop and validate a shorter version of the CANHELP questionnaire. Data were collected using a cross-sectional survey of patients with advanced medical diseases and their family members. Participants completed the long version of CANHELP, a global rating of satisfaction with care (GRS), the FAMCARE scale (family members only), and a quality-of-life (QOL) questionnaire. We reduced the items on the long version based on their relationship to the GRS, the frequency of missing data, the distribution of responses, the redundancy of the items, and focus groups with frontline users. With the remaining items, we assessed internal consistency using Cronbach's alpha, and evaluated construct validity by describing the correlation of the new CANHELP Lite with the full version of CANHELP, GRS, FAMCARE, and the QOL questionnaire scores. A total of 363 patients and 193 family members participated in this study. The patient version was reduced from 37 items to 20 items and the caregiver version was reduced from 38 items to 21 items. Cronbach's alphas ranged from 0.68 to 0.93 for all domains of both the patient and caregiver questionnaires. We observed a high degree of correlation between CANHELP Lite domains and overall scores and the same domains and overall scores for the full version of CANHELP. In addition, we observed moderate to strong correlation between the CANHELP Lite overall satisfaction scores and the GRS questions. There was moderate correlation between the overall family member CANHELP Lite score and overall FAMCARE score (r = 0.45) and this was similar to the correlation between the full version of

    To assess whether the core symptoms of Alzheimer disease (AD) and caregiver factors consistently predict family caregiver ratings of patient quality of life (QOL) as assessed by a variety of QOL measures in a large national sample. : Cross-sectional. Fifteen dementia and geriatric clinics across Canada. : Family caregivers (n = 412) of community-living patients with AD of all severities. Caregiver ratings of patient QOL using three utility indexes, the European Quality of Life-5 Dimensions, Quality of Well-Being Scale and Health Utilities Index; a global QOL visual analogue scale; a disease-specific measure, the Quality of Life-Alzheimer's Disease; and a generic health status measure, the Short Form-36. Patient cognition was assessed with the cognitive subscale of the Alzheimer's Disease Assessment Scale and Mini-Mental State Examination, function with the Disability Assessment for Dementia, and behavioral and psychological symptoms with the Neuropsychiatric Inventory and the Geriatric Depression Scale. Caregiver burden was assessed with the Zarit Burden Interview and caregiver depression with the Center for Epidemiologic Studies Depression scale. One-way analysis of variance and fully adjusted multiple linear regression were used to assess the relationship between patient dementia symptom and caregiver variables with QOL ratings. In multivariable analyses, caregiver ratings of patient function and depressive symptoms were the only consistent independent predictors of caregiver-rated QOL across the QOL measures. Caregiver ratings of patient function and depression were consistent independent predictors of caregiver-rated QOL, using a spectrum of QOL measures, while measures of patient cognition and caregiver burden and depression were not. These findings support the continued use of caregiver ratings as an important source of information about patient QOL and endorse the inclusion in AD clinical trials of caregiver-rated measures of patient function, depression

    Full Text Available BACKGROUND: The Chinese government lists advanced schistosomiasis as a leading healthcare priority due to its serious health and economic impacts, yet it has not been included in the estimates of schistosomiasis burden in the Global Burden of Disease (GBD study. Therefore, the quality of life and disability weight (DW for the advanced cases of schistosomiasis japonica have to be taken into account in the re-estimation of burden of disease due to schistosomiasis. METHODOLOGY/PRINCIPAL FINDINGS: A patient-based quality-of-life evaluation was performed for advanced schistosomiasis japonica. Suspected or officially registered advanced cases in a Schistosoma japonicum-hyperendemic county of the People's Republic of China (P.R. China were screened using a short questionnaire and physical examination. Disability and morbidity were assessed in confirmed cases, using the European quality of life questionnaire with an additional cognitive dimension (known as the "EQ-5D plus", ultrasonography, and laboratory testing. The age-specific DW of advanced schistosomiasis japonica was estimated based on patients' self-rated health scores on the visual analogue scale of the questionnaire. The relationships between health status, morbidity and DW were explored using multivariate regression models. Of 506 candidates, 215 cases were confirmed as advanced schistosomiasis japonica and evaluated. Most of the patients reported impairments in at least one health dimension, such as pain or discomfort (90.7%, usual activities (87.9%, and anxiety or depression (80.9%. The overall DW was 0.447, and age-specific DWs ranged from 0.378 among individuals aged 30-44 years to 0.510 among the elderly aged ≥ 60 years. DWs are positively associated with loss of work capacity, psychological abnormality, ascites, and active hepatitis B virus, while splenectomy and high albumin were protective factors for quality of life. CONCLUSIONS/SIGNIFICANCE: These patient-preference disability

    To study the health and health practices of Canadian physicians, which can often influence patient health. Mailed survey. Canada. A random sample of 8100 Canadian physicians; 7934 were found to be eligible and 3213 responded (40.5% response rate). Factors that influence health, such as consumption of fruits and vegetables, amount of exercise and alcohol consumption, smoking status, body mass idex, and participation in preventive health screening measures, as well as work-life balance and emotional stability. Canadian physicians are healthy. More than 90% reported being in good to excellent health, and only 5% reported that poor physical or mental health made it difficult to handle their workload more than half the time in the previous month (although a quarter had reduced work activity because of long-term health conditions). Eight percent were obese, 3% currently smoked cigarettes, and 1% typically consumed 5 drinks or more on days when they drank alcohol. Physicians averaged 4.7 hours of exercise per week and ate fruits and vegetables 4.8 times a day. Their personal screening practices were largely compliant with Canadian Task Force on Preventive Health Care recommendations. They averaged 38 hours per week on patient care and 11 hours on other professional activities. Fifty-seven percent agreed that they had a good work-life balance, and 11% disagreed with the statement "If I can, I work when I am ill." Compared with self-reports from the general Canadian population, Canadian physicians, like American physicians, seem to be healthy and to have generally healthy behaviour. There is, however, room for improvement in physicians' personal and professional well-being, and improving their personal health practices could be an efficient and beneficent way to improve the health of all Canadians.

    Using prospective data from the Canadian Multicentre Osteoporosis Study (CaMos), we compared health utilities index (HUI) scores after 5 years of follow-up among participants (50 years and older) with and without incident clinical fractures. Incident fractures had a negative impact on HUI scores over time. This study examined change in health-related quality of life (HRQL) in those with and without incident clinical fractures as measured by the HUI. The study cohort was 4,820 women and 1,783 men (50 years and older) from the CaMos. The HUI was administered at baseline and year 5. Participants were sub-divided into incident fracture groups (hip, rib, spine, forearm, pelvis, other) and were compared with those without these fractures. The effects of both time and fracture type on HUI scores were examined in multivariable regression analyses. Men and women with hip fractures, compared to those without, had lower HUI measures that ranged from -0.05 to -0.25. Both women and men with spine fractures had significant deficits on the pain attributes (-0.07 to -0.12). In women, self-care (-0.06), mobility and ambulation (-0.05) were also negatively impacted. Women with rib fractures had deficits similar to women with spine fractures, and these effects persisted over time. In men, rib fractures did not significantly affect HUI scores. Pelvic and forearm fractures did not substantially influence HUI scores. The HUI was a sensitive measure of HRQL change over time. These results will inform economic analyses evaluating osteoporosis therapies.

    Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc. Subjects were recruited from the Canadian Scleroderma Research Group registry. Global HRQoL was measured using the Medical Outcomes Trust 36-item Short Form Health Survey (SF-36) and oral HRQoL with the Oral Health Impact Profile (OHIP). The Medsger Disease Severity Score was used to determine organ involvement. Multivariate regression models determined the independent association of the OHIP with the SF-36 after adjusting for confounders. This study included 156 SSc subjects. The majority (90%) were women, with a mean age of 56 years, mean disease duration 13.8 years (s.d. 8.5) and 29% of the subjects had dcSSc. Mean total OHIP score was 40.8 (s.d. 32.4). Mean SF-36 mental component summary (MCS) score was 49.7 (s.d. 11.1) and physical component summary (PCS) score was 37.0 (s.d. 10.7). In adjusted analyses, the total OHIP score was significantly associated with the SF-36 MCS and PCS, accounting for 9.7% and 5.6% of their respective variances. Measures of disease severity were not related to OHIP score. Oral HRQoL in SSc is independently associated with global HRQoL. Oral HRQoL, however, is not related to physician-assessed disease severity. This suggests that physicians may be disregarding issues related to oral health. HRQoL is an additional dimension of HRQoL not captured by generic instruments such as the SF-36. © The Author 2014.

    A study of patients with advanced maxillary sinus cancer who underwent radical or conservative maxillectomy was performed to show the differences between the 2 groups in patients' survival rate and quality of life (QOL). A total of 61 advanced maxillary sinus cancer patients from Weifang People's Hospital in China were traced: 27 radical maxillectomy and 34 conservative maxillectomy. Survival rate was compared between the 2 groups. Quality of life assessments were performed at the time of preoperation as well as 6, 12, and 18 months after the operation. Measures included the University of Washington-QOL scale (UW-QOL) and the Hospital Anxiety and Depression Scale. The UW-QOL scale scores of the composite score, appearance, activity, recreation, swallowing, speech, and chewing in the conservative surgical group were much higher than those in the radical surgical group. However, there is no big difference in total survival rate between these 2 groups. Also, no significant difference can be seen in the scores of pain, employment, and shoulder between the 2 groups. At the 6-month follow-up, the radical maxillectomy had more effects on anxiety than the conservative maxillectomy, while they are almost equally effective on depression. The 12-month and 18-month follow-ups showed that the radical maxillectomy made a greater impact on both anxiety and depression than the conservative maxillectomy. Conservative maxillectomy is more effective than radical maxillectomy to preserve the QOL of patients with advanced maxillary sinus cancer.

A cross-sectional study involving 494 patients with advanced cancer was conducted using the Memorial Symptom Assessment Scale-Short Form, the Karnofsky Performance Status Scale, the World Health Organization Disability Assessment Schedule (Korean version), and the European Organization for Research and Treatment of Cancer Quality of Life Core 30. Regression analyses showed that physical and psychological symptoms significantly predicted the patients' QOL and explained 28.8% of the variance in QOL. Moreover, lack of energy was the patients' most prevalent symptom. The results of the present study will serve as fundamental data upon which the development of an intervention will be based so as to enhance the patients' QOL. Accordingly, an effective management of symptoms and performance maintenance should be considered in the future as key factors in providing support and establishing palliative care systems for patients with advanced cancer.

    Students are exposed to basic life support (BLS) and advanced cardiac life support (ACLS) training in the first semester in some medical colleges. The aim of this study was to compare students' satisfaction between lecture-based traditional method and hybrid problem-based learning (PBL) in BLS/ACLS teaching to undergraduate medical students. We conducted a questionnaire-based, cross-sectional survey among 118 1 st -year medical students from a university medical college in the city of New Delhi, India. We aimed to assess the students' satisfaction between lecture-based and hybrid-PBL method in BLS/ACLS teaching. Likert 5-point scale was used to assess students' satisfaction levels between the two teaching methods. Data were collected and scores regarding the students' satisfaction levels between these two teaching methods were analysed using a two-sided paired t -test. Most students preferred hybrid-PBL format over traditional lecture-based method in the following four aspects; learning and understanding, interest and motivation, training of personal abilities and being confident and satisfied with the teaching method ( P < 0.05). Implementation of hybrid-PBL format along with the lecture-based method in BLS/ACLS teaching provided high satisfaction among undergraduate medical students.

  12. Experimental Creep Life Assessment for the Advanced Stirling Convertor Heater Head

    The United States Department of Energy is planning to develop the Advanced Stirling Radioisotope Generator (ASRG) for the National Aeronautics and Space Administration (NASA) for potential use on future space missions. The ASRG provides substantial efficiency and specific power improvements over radioisotope power systems of heritage designs. The ASRG would use General Purpose Heat Source modules as energy sources and the free-piston Advanced Stirling Convertor (ASC) to convert heat into electrical energy. Lockheed Martin Corporation of Valley Forge, Pennsylvania, is integrating the ASRG systems, and Sunpower, Inc., of Athens, Ohio, is designing and building the ASC. NASA Glenn Research Center of Cleveland, Ohio, manages the Sunpower contract and provides technology development in several areas for the ASC. One area is reliability assessment for the ASC heater head, a critical pressure vessel within which heat is converted into mechanical oscillation of a displacer piston. For high system efficiency, the ASC heater head operates at very high temperature (850 C) and therefore is fabricated from an advanced heat-resistant nickel-based superalloy Microcast MarM-247. Since use of MarM-247 in a thin-walled pressure vessel is atypical, much effort is required to assure that the system will operate reliably for its design life of 17 years. One life-limiting structural response for this application is creep; creep deformation is the accumulation of time-dependent inelastic strain under sustained loading over time. If allowed to progress, the deformation eventually results in creep rupture. Since creep material properties are not available in the open literature, a detailed creep life assessment of the ASC heater head effort is underway. This paper presents an overview of that creep life assessment approach, including the reliability-based creep criteria developed from coupon testing, and the associated heater head deterministic and probabilistic analyses. The approach also

    NASA has completed an environmental control and life support system (ECLSS) technology R&D plan for advanced missions which gave attention to the drivers (crew size, mission duration, etc.) of a range of manned missions under consideration. Key planning guidelines encompassed a time horizon greater than 50 years, funding resource requirements, an evolutionary approach to goal definition, and the funding of more than one approach to satisfy a given perceived requirement. Attention was given to the ECLSS requirements of transportation and service vehicles, platforms, bases and settlements, ECLSS functions and average load requirements, unique drivers for various missions, and potentially exploitable commonalities among vehicles and habitats.

  16. Advancing Life Projects: South African Students Explain Why They Come to FET Colleges

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Vocational Education and Training (VET policy in South Africa is based on a narrow set of assumptions regarding the identity of learners and the reasons that they are in public further education and training (FET colleges. These assumptions reflect an international orthodoxy about the centrality of employability that is located within what Giddens (1994 has described as 'productivism', a view that reduces life to the economic sphere. Through exploring the stories of a group of South African public FET college learners' regarding their reasons for choosing FET colleges, this paper shows that VET is valued by these students for a range of reasons. These include preparation for the world of work, but also a desire to improve their ability to contribute to their communities and families; raise their self-esteem; and expand their future life possibilities. Thus, the paper advances the largely hitherto theoretical critique of productivist VET accounts by offering empirical evidence of counter-narratives.

    2013-01-01

    Significance African Americans with cancer are less likely to use hospice services and more likely to die in the hospital than white patients with the same diagnosis. However, there is much that is not understood about the factors that lead African Americans to choose options for end-of-life care. Design A qualitative, descriptive design was used in this pilot study. Methods Interviews were conducted with two groups of African Americans with advanced-stage cancer (people enrolled in hospice and those who were not under hospice care). Findings End-of-life decisions were primarily guided by clinical factors, the patient-related physical, emotional, and cognitive symptoms that are sequelae of the underlying disease or medical treatments. The physician was the healthcare provider most likely to be involved in decision making with patients, family members, and caregivers. Individual factors, such as personal beliefs, influenced end-of-life decision making. Religion and spirituality were a topic in many interviews, but they did not consistently influence decision making. Discussion Future studies should include interviews with family members, caregivers, and healthcare professionals so that factors that impact end-of-life decision making can be fully described. Strategies to facilitate recruitment will need to be added to future protocols. PMID:23645999

    The use of plants for bioregenerative life support for space missions was first studied by the US Air Force in the 1950s and 1960s. Extensive testing was also conducted from the 1960s through the 1980s by Russian researchers located at the Institute of Biophysics in Krasnoyarsk, Siberia, and the Institute for Biomedical Problems in Moscow. NASA initiated bioregenerative research in the 1960s (e.g., Hydrogenomonas) but this research did not include testing with plants until about 1980, with the start of the Controlled Ecological Life Support System (CELSS) Program. The NASA CELSS research was carried out at universities, private corporations, and NASA field centers, including Kennedy Space Center (KSC). The project at KSC began in 1985 and was called the CELSS Breadboard Project to indicate the capability for plugging in and testing various life support technologies; this name has since been dropped but bioregenerative testing at KSC has continued to the present under the NASA s Advanced Life Support (ALS) Program. A primary objective of the KSC testing was to conduct pre-integration tests with plants (crops) in a large, atmospherically closed test chamber called the Biomass Production Chamber (BPC). Test protocols for the BPC were based on observations and growing procedures developed by university investigators, as well as procedures developed in plant growth chamber studies at KSC. Growth chamber studies to support BPC testing focused on plant responses to different carbon dioxide (CO2) concentrations, different spectral qualities from various electric lamps, and nutrient film hydroponic culture techniques.

    Patient-clinician communication is an important prerequisite to delivering high-quality end-of-life care. However, discussions about end-of-life care are uncommon in patients with advanced chronic organ failure. The aim was to examine the quality of end-of-life care communication during one year follow-up of patients with advanced chronic organ failure. In addition, we aimed to explore whether and to what extent quality of communication about end-of-life care changes toward the end of life and whether end-of-life care communication is related to patient-perceived quality of medical care. Clinically stable outpatients (n = 265) with advanced chronic obstructive pulmonary disease, chronic heart failure, or chronic renal failure were visited at home at baseline and four, eight, and 12 months after baseline to assess quality of end-of-life care communication (Quality of Communication questionnaire). Two years after baseline, survival status was assessed, and if patients died during the study period, a bereavement interview was done with the closest relative. One year follow-up was completed by 77.7% of the patients. Quality of end-of-life care communication was rated low at baseline and did not change over one year. Quality of end-of-life care communication was comparable for patients who completed two year follow-up and patients who died during the study. The correlation between quality of end-of-life care communication and satisfaction with medical treatment was weak. End-of-life care communication is poor in patients with chronic organ failure and does not change toward the end of life. Future studies should develop an intervention aiming at initiating high-quality end-of-life care communication between patients with advanced chronic organ failure and their clinicians.

    Advanced Life Support (ALS) providers may perform more invasive prehospital procedures, while Basic Life Support (BLS) providers offer stabilisation care and often "scoop and run". We hypothesised that prehospital interventions by urban ALS providers prolong prehospital time and decrease survival in penetrating trauma victims. We prospectively analysed 236 consecutive ambulance-transported, penetrating trauma patients an our urban Level-1 trauma centre (6/2008-12/2009). Inclusion criteria included ICU admission, length of stay >/=2 days, or in-hospital death. Demographics, clinical characteristics, and outcomes were compared between ALS and BLS patients. Single and multiple variable logistic regression analysis determined predictors of hospital survival. Of 236 patients, 71% were transported by ALS and 29% by BLS. When ALS and BLS patients were compared, no differences in age, penetrating mechanism, scene GCS score, Injury Severity Score, or need for emergency surgery were detected (p>0.05). Patients transported by ALS units more often underwent prehospital interventions (97% vs. 17%; p<0.01), including endotracheal intubation, needle thoracostomy, cervical collar, IV placement, and crystalloid resuscitation. While ALS ambulance on-scene time was significantly longer than that of BLS (p<0.01), total prehospital time was not (p=0.98) despite these prehospital interventions (1.8 ± 1.0 per ALS patient vs. 0.2 ± 0.5 per BLS patient; p<0.01). Overall, 69.5% ALS patients and 88.4% of BLS patients (p<0.01) survived to hospital discharge. Prehospital resuscitative interventions by ALS units performed on penetrating trauma patients may lengthen on-scene time but do not significantly increase total prehospital time. Regardless, these interventions did not appear to benefit our rapidly transported, urban penetrating trauma patients. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The objective of the environmental control and life support system (ECLSS) Advanced Automation Project is to influence the design of the initial and evolutionary Space Station Freedom Program (SSFP) ECLSS toward a man-made closed environment in which minimal flight and ground manpower is needed. Another objective includes capturing ECLSS design and development knowledge future missions. Our approach has been to (1) analyze the SSFP ECLSS, (2) envision as our goal a fully automated evolutionary environmental control system - an augmentation of the baseline, and (3) document the advanced software systems, hooks, and scars which will be necessary to achieve this goal. From this analysis, prototype software is being developed, and will be tested using air and water recovery simulations and hardware subsystems. In addition, the advanced software is being designed, developed, and tested using automation software management plan and lifecycle tools. Automated knowledge acquisition, engineering, verification and testing tools are being used to develop the software. In this way, we can capture ECLSS development knowledge for future use develop more robust and complex software, provide feedback to the knowledge based system tool community, and ensure proper visibility of our efforts.

    The objective was the comparison of the quality of life in patients with advanced laryngeal cancer treated with organ preservation versus surgical treatment. We performed a systematic review in the databases MedLine, EMBASE, and PubMed (2014 1991) and Web of Science (2012 - 2014). The search terms were: Laryngeal cancer, organ preservation, chemotherapy, laryngectomy, treatment outcomes and quality of life. Systematic reviews, meta-analysis, reports of health technology assessment and comparative studies with control group, published in Spanish, French or English were included. The selection and quality assessment was made by two researchers. The criteria of the Cochrane Collaboration were used to assess the risk of bias and Scottish Intercollegiate Guidelines Network (SIGN) for the level of evidence. Of the 208 studies identified in the search, three were included a clinical trial and two observational studies, with a total of 211 patients. Quality and level of evidence was low. The results were contradictory, on occasion they favoured surgery, and on other occasions chemotherapy, but in general there were no statistical differences between the treatments. The studies were heterogeneous, with different methodology, undersized, limitations in quality with high risk of bias and use of different measurement scales. There are not enough studies of quality to establish differences in the quality of life in patients with advanced laryngeal cancer according to the treatment received.

    Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), and Pediatric Advanced Life Support (PALS) are integral parts of emergency resuscitative care. Although this training is usually reserved for residents, introducing the training in the medical student curriculum may enhance acquisition and retention of these skills. We developed a survey to characterize the perceptions and needs of graduating medical students regarding BLS, ACLS, and PALS training. This was a study of graduating 4th-year medical students at a U.S. medical school. The students were surveyed prior to participating in an ACLS course in March of their final year. Of 152 students, 109 (71.7%) completed the survey; 48.6% of students entered medical school without any prior training and 47.7% started clinics without training; 83.4% of students reported witnessing an average of 3.0 in-hospital cardiac arrests during training (range of 0-20). Overall, students rated their preparedness 2.0 (SD 1.0) for adult resuscitations and 1.7 (SD 0.9) for pediatric resuscitations on a 1-5 Likert scale, with 1 being unprepared. A total of 36.8% of students avoided participating in resuscitations due to lack of training; 98.2%, 91.7%, and 64.2% of students believe that BLS, ACLS, and PALS, respectively, should be included in the medical student curriculum. As per previous studies that have examined this topic, students feel unprepared to respond to cardiac arrests and resuscitations. They feel that training is needed in their curriculum and would possibly enhance perceived comfort levels and willingness to participate in resuscitations. Copyright © 2014 Elsevier Inc.

    Most Medicare patients seeking emergency medical transport are treated by ambulance providers trained in advanced life support (ALS). Evidence supporting the superiority of ALS over basic life support (BLS) is limited, but some studies suggest ALS may harm patients. To compare outcomes after ALS and BLS in out-of-hospital medical emergencies. Observational study with adjustment for propensity score weights and instrumental variable analyses based on county-level variations in ALS use. Traditional Medicare. 20% random sample of Medicare beneficiaries from nonrural counties between 2006 and 2011 with major trauma, stroke, acute myocardial infarction (AMI), or respiratory failure. Neurologic functioning and survival to 30 days, 90 days, 1 year, and 2 years. Except in cases of AMI, patients showed superior unadjusted outcomes with BLS despite being older and having more comorbidities. In propensity score analyses, survival to 90 days among patients with trauma, stroke, and respiratory failure was higher with BLS than ALS (6.1 percentage points [95% CI, 5.4 to 6.8 percentage points] for trauma; 7.0 percentage points [CI, 6.2 to 7.7 percentage points] for stroke; and 3.7 percentage points [CI, 2.5 to 4.8 percentage points] for respiratory failure). Patients with AMI did not exhibit differences in survival at 30 days but had better survival at 90 days with ALS (1.0 percentage point [CI, 0.1 to 1.9 percentage points]). Neurologic functioning favored BLS for all diagnoses. Results from instrumental variable analyses were broadly consistent with propensity score analyses for trauma and stroke, showed no survival differences between BLS and ALS for respiratory failure, and showed better survival at all time points with BLS than ALS for patients with AMI. Only Medicare beneficiaries from nonrural counties were studied. Advanced life support is associated with substantially higher mortality for several acute medical emergencies than BLS.

    2008-07-01

    The present study was the first cross-national examination of whether managers who were perceived to be high in work-life balance were expected to be more or less likely to advance in their careers than were less balanced, more work-focused managers. Using self ratings, peer ratings, and supervisor ratings of 9,627 managers in 33 countries, the authors examined within-source and multisource relationships with multilevel analyses. The authors generally found that managers who were rated higher in work-life balance were rated higher in career advancement potential than were managers who were rated lower in work-life balance. However, national gender egalitarianism, measured with Project GLOBE scores, moderated relationships based on supervisor and self ratings, with stronger positive relationships in low egalitarian cultures. The authors also found 3-way interactions of work-life balance ratings, ratee gender, and gender egalitarianism in multisource analyses in which self balance ratings predicted supervisor and peer ratings of advancement potential. Work-life balance ratings were positively related to advancement potential ratings for women in high egalitarian cultures and men in low gender egalitarian cultures, but relationships were nonsignificant for men in high egalitarian cultures and women in low egalitarian cultures.

    Purpose Religion and spirituality play a role in coping with illness for many cancer patients. This study examined religiousness and spiritual support in advanced cancer patients of diverse racial/ethnic backgrounds and associations with quality of life (QOL), treatment preferences, and advance care planning. Methods The Coping With Cancer study is a federally funded, multi-institutional investigation examining factors associated with advanced cancer patient and caregiver well-being. Patients with an advanced cancer diagnosis and failure of first-line chemotherapy were interviewed at baseline regarding religiousness, spiritual support, QOL, treatment preferences, and advance care planning. Results Most (88%) of the study population (N = 230) considered religion to be at least somewhat important. Nearly half (47%) reported that their spiritual needs were minimally or not at all supported by a religious community, and 72% reported that their spiritual needs were supported minimally or not at all by the medical system. Spiritual support by religious communities or the medical system was significantly associated with patient QOL (P = .0003). Religiousness was significantly associated with wanting all measures to extend life (odds ratio, 1.96; 95% CI, 1.08 to 3.57). Conclusion Many advanced cancer patients' spiritual needs are not supported by religious communities or the medical system, and spiritual support is associated with better QOL. Religious individuals more frequently want aggressive measures to extend life. PMID:17290065

  13. Evaluation of environmental impacts of cellulosic ethanol using life cycle assessment with technological advances over time

    International Nuclear Information System (INIS)

    Pawelzik, Paul F.; Zhang, Qiong

    2012-01-01

    Life Cycle Assessment (LCA) has been used in quantifying the environmental impacts of materials, processes, products, or systems across their entire lifespan from creation to disposal. To evaluate the environmental impact of advancing technology, Life Cycle Assessment with Technological Advances over Time (LCA-TAT) incorporates technology improvements within the traditional LCA framework. In this paper, the LCA-TAT is applied to quantify the environmental impacts of ethanol production using cellulosic biomass as a feedstock through the simultaneous saccharification and co-fermentation (SSCF) process as it improves over time. The data for the SSCF process are taken from the Aspen Plus ® simulation developed by the National Renewable Energy Lab (NREL). The Environmental Fate and Risk Assessment Tool (EFRAT) is used to calculate the fugitive emissions and SimaPro 7.1 software is used to quantify the environmental impacts of processes. The impact indicators of the processes are calculated using the Eco-indicator 95 method; impact categories analyzed include ozone layer depletion, heavy metals, carcinogens, summer smog, winter smog, pesticides, greenhouse effect, acidification, and eutrophication. Based on the LCA-TAT results, it is found that removal of the continuous ion exchange step within the pretreatment area increases the environmental impact of the process. The main contributor to the increase in the environmental impact of the process is the heavy metal indicator. In addition, a sensitivity analysis is performed to identify major inputs and outputs that affect environmental impacts of the overall process. Based on this analysis it is observed that an increase in waste production and acid use have the greatest effect on the environmental impacts of the SSCF process. Comparing economic analysis with projected technological advances performed by NREL, the improvement in environmental impact was not matched by a concomitant improvement in economic performance. In

    Next Generation Life Support (NGLS) is one of several technology development projects sponsored by the National Aeronautics and Space Administration s Game Changing Development Program. NGLS is developing life support technologies (including water recovery, and space suit life support technologies) needed for humans to live and work productively in space. NGLS has three project tasks: Variable Oxygen Regulator (VOR), Rapid Cycle Amine (RCA) swing bed, and Alternative Water Processing. The selected technologies within each of these areas are focused on increasing affordability, reliability, and vehicle self sufficiency while decreasing mass and enabling long duration exploration. The RCA and VOR tasks are directed at key technology needs for the Portable Life Support System (PLSS) for an Exploration Extravehicular Mobility Unit (EMU), with focus on prototyping and integrated testing. The focus of the Rapid Cycle Amine (RCA) swing-bed ventilation task is to provide integrated carbon dioxide removal and humidity control that can be regenerated in real time during an EVA. The Variable Oxygen Regulator technology will significantly increase the number of pressure settings available to the space suit. Current spacesuit pressure regulators are limited to only two settings while the adjustability of the advanced regulator will be nearly continuous. The Alternative Water Processor efforts will result in the development of a system capable of recycling wastewater from sources expected in future exploration missions, including hygiene and laundry water, based on natural biological processes and membrane-based post treatment. The technologies will support a capability-driven architecture for extending human presence beyond low Earth orbit to potential destinations such as the Moon, near Earth asteroids and Mars.

    1998-01-01

    A concentrated development effort was begun at NASA Johnson Space Center to create an advanced Portable Life Support System (PLSS) packaging concept. Ease of maintenance, technological flexibility, low weight, and minimal volume are targeted in the design of future micro-gravity and planetary PLSS configurations. Three main design concepts emerged from conceptual design techniques and were carried forth into detailed design, then full scale mock-up creation. "Foam", "Motherboard", and "LEGOtm" packaging design concepts are described in detail. Results of the evaluation process targeted maintenance, robustness, mass properties, and flexibility as key aspects to a new PLSS packaging configuration. The various design tools used to evolve concepts into high fidelity mock ups revealed that no single tool was all encompassing, several combinations were complimentary, the devil is in the details, and, despite efforts, many lessons were learned only after working with hardware.

    Isacson, D; Bingefors, K; Kristiansen, I S; Nyholm, D

    2008-12-01

    To assess fluctuations in quality of life (QoL) and motor performance in patients with advanced Parkinson disease (PD) treated with continuous daytime duodenal levodopa/carbidopa infusion or conventional therapy. Of 18 patients completing a 6-week trial (DIREQT), 12 were followed for up to 6 months and assessed using electronic diaries and the PD Questionnaire-39 (PDQ-39). During the trial and follow-up, major diurnal fluctuations were observed, especially for hyperkinesia, 'off' time, ability to walk and depression. Duodenal infusion was associated with significantly more favourable outcomes compared with conventional treatment for satisfaction with overall functioning, 'off' time and ability to walk, with improved outcomes with PDQ-39. Relative to conventional treatment, infusion therapy may stabilize and significantly improve motor function and patient's QoL. The potential for daily fluctuation in PD symptoms means single measures of treatment effectiveness can result in bias in effect estimates and hence repeated measures are recommended.

    Sodium is an essential dietary requirement in human nutrition, but seldom holds much importance as a nutritional element for crop plants. In Advanced Life Support (ALS) systems, recycling of gases, nutrients, and water loops is required to improve system closure. If plants are to play a significant role in recycling of human wastes, Na will need to accumulate in edible tissues for return to the crew diet. If crops fail to accumulate the incoming Na into edible tissues, Na could become a threat to the hydroponic food production system by increasing the nutrient solution salinity. Vegetable crops of Chenopodiaceae such as spinach, table beet, and chard may have a high potential to supply Na to the human diet, as Na can substitute for K to a large extent in metabolic processes of these crops. Various strategies are outlined that include both genetic and environmental management aspects to optimize the Na recovery from waste streams and their resupply through the human diet in ALS.

    Prior to determining what Solid Waste Management (SWM) technologies should be researched and developed by the Advanced Life Support (ALS) Project for future missions, there is a need to define SWM requirements. Because future waste streams will be highly mission-dependent, missions need to be defined prior to developing SWM requirements. The SWM Working Group has used the mission architecture outlined in the System Integration, Modeling and Analysis (SIMA) Element Reference Missions Document (RMD) as a starting point in the requirement development process. The missions examined include the International Space Station (ISS), a Mars Dual Lander mission, and a Mars Base. The SWM Element has also identified common SWM functionalities needed for future missions. These functionalities include: acceptance, transport, processing, storage, monitoring and control, and disposal. Requirements in each of these six areas are currently being developed for the selected missions. This paper reviews the results of this ongoing effort and identifies mission-dependent resource recovery requirements.

    Objective. To assess the impact of an advanced cardiac life support (ACLS) simulation on pharmacy student confidence and knowledge. Design. Third-year pharmacy students participated in a simulation experience that consisted of team roles training, high-fidelity ACLS simulations, and debriefing. Students completed a pre/postsimulation confidence and knowledge assessment. Assessment. Overall, student knowledge assessment scores and student confidence scores improved significantly. Student confidence and knowledge changes from baseline were not significantly correlated. Conversely, a significant, weak positive correlation between presimulation studying and both presimulation confidence and presimulation knowledge was discovered. Conclusions. Overall, student confidence and knowledge assessment scores in ACLS significantly improved from baseline; however, student confidence and knowledge were not significantly correlated.

    Quality of life (QoL) assessment questionnaires can be burdensome to advanced cancer patients, thus necessitating the need for shorter assessment instruments than traditionally available. We compare three shortened QoL questionnaires in regards to their characteristics, validity, and reliability. A literature search was conducted to identify studies that employed or discussed three abridged QoL questionnaires: the European Organization for Research and Treatment of Cancer Quality of Life Core 15-Palliative Care (EORTC QLQ-C15-PAL), the Functional Assessment of Cancer Therapy-General-7 (FACT-G7), and the Functional Assessment of Chronic Illness Therapy-Palliative Care-14 (FACIT-PAL-14). Articles that discussed questionnaire length, intended use, scoring procedure, and validation were included. The 7-item FACT-G7 is the shortest instrument, whereas the EORTC QLQ-C15-PAL and the FACIT-PAL-14 contain 14 and 15 items, respectively. All three questionnaires have similar recall period, item organization, and subscale components. Designed as core questionnaires, all three maintain content and concurrent validity of their unabridged original questionnaires. Both the EORTC QLQ-C15-PAL and the FACT-G7 demonstrate good internal consistency and reliability, with Cronbach's α ≥0.7 deemed acceptable. The developmental study for the FACIT-PAL-14 was published in 2013 and subsequent validation studies are not yet available. The EORTC QLQ-C15-PAL and the FACT-G7 were found to be reliable and appropriate for assessing health-related QoL issues-the former for palliative cancer patients and the latter for advanced cancer patients receiving chemotherapy. Conceptually, the FACIT-PAL-14 holds promise to cover social and emotional support issues that are not completely addressed by the other two questionnaires; however, further validation is needed.

    Full Text Available Abstract Background To determine the advanced life support procedures provided by an Emergency Medical Service (EMS and a Helicopter Emergency Medical Service (HEMS for vitally compromised children. Incidence and success rate of several procedures were studied, with a distinction made between procedures restricted to the HEMS-physician and procedures for which the HEMS is more experienced than the EMS. Methods Prospective study of a consecutive group of children examined and treated by the HEMS of the eastern region of the Netherlands. Data regarding type of emergency, physiological parameters, NACA scores, treatment, and 24-hour survival were collected and subsequently analysed. Results Of the 558 children examined and treated by the HEMS on scene, 79% had a NACA score of IV-VII. 65% of the children had one or more advanced life support procedures restricted to the HEMS and 78% of the children had one or more procedures for which the HEMS is more experienced than the EMS. The HEMS intubated 38% of all children, and 23% of the children intubated and ventilated by the EMS needed emergency correction because of potentially lethal complications. The HEMS provided the greater part of intraosseous access, as the EMS paramedics almost exclusively reserved this procedure for children in cardiopulmonary resuscitation. The EMS provided pain management only to children older than four years of age, but a larger group was in need of analgesia upon arrival of the HEMS, and was subsequently treated by the HEMS. Conclusions The Helicopter Emergency Medical Service of the eastern region of the Netherlands brings essential medical expertise in the field not provided by the emergency medical service. The Emergency Medical Service does not provide a significant quantity of procedures obviously needed by the paediatric patient.

    In 2013, the Pediatric Association of the Netherlands launched an evidence-based guideline 'Palliative care for children'. To promote implementation in daily practice and hereby improve quality of paediatric palliative care, we aimed to develop a functional individualised paediatric palliative care plan (IPPCP) that covers physical, psychological, spiritual and social functioning, with great emphasis on the guideline's recommendations, advance care planning and patients' and parents' preferences and desires. A Dutch working group (28 individuals) with a strong multidisciplinary character developed a draft IPPCP, which was piloted retrospectively and prospectively. In the pilots we completed, the IPPCPs for patients who were recently diagnosed with a life-threatening or life-limiting condition and evaluated completeness, usability and user-friendliness. The final IPPCP comprised five domains: (1) IPPCP data, (2) basics, (3) social, (4) psychosocial and spiritual and (5) physical care. Each domain covered various components. In both pilots, the IPPCP was considered a comprehensive document that covered all areas of paediatric palliative care and was experienced as an improvement to the present situation. However, the current form was regarded to lack user-friendliness. We propose a set of essential components of a comprehensive IPPCP for paediatric palliative care with extra attention for advance care planning and anticipatory action. Patients' and parents' preferences and desires are included next to the recommendations of the evidence-based guideline 'Palliative care for children'. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To establish variables which are associated with favourable Advanced Life Support (ALS) course assessment outcomes, maximising learning effect. Between 1 January 2013 and 30 June 2014, 8218 individuals participated in a Resuscitation Council (UK) e-learning Advanced Life Support (e-ALS) course. Participants completed 5-8h of online e-learning prior to attending a one day face-to-face course. e-Learning access data were collected through the Learning Management System (LMS). All participants were assessed by a multiple choice questionnaire (MCQ) before and after the face-to-face aspect alongside a practical cardiac arrest simulation (CAS-Test). Participant demographics and assessment outcomes were analysed. The mean post e-learning MCQ score was 83.7 (SD 7.3) and the mean post-course MCQ score was 87.7 (SD 7.9). The first attempt CAS-Test pass rate was 84.6% and overall pass rate 96.6%. Participants with previous ALS experience, ILS experience, or who were a core member of the resuscitation team performed better in the post-course MCQ, CAS-Test and overall assessment. Median time spent on the e-learning was 5.2h (IQR 3.7-7.1). There was a large range in the degree of access to e-learning content. Increased time spent accessing e-learning had no effect on the overall result (OR 0.98, P=0.367) on simulated learning outcome. Clinical experience through membership of cardiac arrest teams and previous ILS or ALS training were independent predictors of performance on the ALS course whilst time spent accessing e-learning materials did not affect course outcomes. This supports the blended approach to e-ALS which allows participants to tailor their e-learning experience to their specific needs. Copyright © 2017 Elsevier B.V. All rights reserved.

    This paper joins the debate over changes in the role of health professionals when applying advance directives to manage the decision-making process at the end of life care. Issues in relation to advance directives occur in clinical units in Lithuania; however, it remains one of the few countries in the European Union (EU) where the discussion on advance directives is not included in the health-care policy-making agenda. To encourage the discussion of advance directives, a study was designed to examine health professionals' understanding and preferences related to advance directives. In addition, the study sought to explore the views of health care professionals of the application of Advance Directives (AD) in clinical practice in Lithuania. A cross-sectional survey was conducted by interviewing 478 health professionals based at major health care centers in Kaunas district, Lithuania. The design of the study included the use of a questionnaire developed for this study and validated by a pilot study. The collected data were analyzed using standard descriptive statistical methods. The analysis of knowledge about AD revealed some statistically significant differences when comparing the respondents' profession and gender. The analysis also indicated key emerging themes among respondents including tranquility of mind, the longest possible life expectancy and freedom of choice. Further, the study findings revealed that more than half of the study participants preferred to express their will while alive by using advance directives. The study findings revealed a low level of knowledge on advance directives among health professionals. Most health professionals agreed that AD's improved end-of-life decision making while the majority of physicians appreciated AD as the best tool for sharing responsibilities in clinical practice in Lithuania. More physicians than nurses preferred the presence of advance directives to support their decision making in end-of-life situations.

    Statistics on fires has surprisingly shown that the frequency of fires in a nuclear power plant are as high as in the conventional industrial units. The analyses on fires occurred in a NPP need to consider both their well-known severe damages and the nuclear consequences. In 1975 a severe fire occurred in BROWNS FERRY NPP due to the ignition of the polyurethane foam used in the electric cable penetration sealings. The fire propagated to the cable channels and damaged over 1600 cables. The fire event revealed important shortcomings in the fire protection design and procedures. The fire represented a crucial event that changed fundamentally the fire protection regulation in the United States nuclear industry. The fire protection programs, standards and guides currently applied, have been developed on basis of this fire analysis and gained conclusions/experience. The purpose of the article is to be a short presentation of the fire protection requirements for all NPP life stages (i.e. design, construction, commissioning, operation and decommissioning), including the most recent issues of the standards, codes, guides and regulations in US, Canada, IAEA and some European countries. Such documentation represented the main technical support in establishing the national fire protection standard design regarding all the stages of a CANDU-6 NPP life, all the types of operational NPPs, particularly for Cernavoda NPP Unit 1 and Unit 2 (now in an advanced stage of construction). In order to satisfy the requirements provided by this documentation, as practically as possible, a list of analyses and fire protection improvement measures for Cernavoda NPP is presented. (authors)

    During the summer 1998, I did student assistance to Dr. Daniel J. Barta, chief plant growth expert at Johnson Space Center - NASA. We established the preliminary stages of a hydroponic crop growth database for the Advanced Life Support Systems Integration Test Bed, otherwise referred to as BIO-Plex (Biological Planetary Life Support Systems Test Complex). The database summarizes information from published technical papers by plant growth experts, and it includes bibliographical, environmental and harvest information based on plant growth under varying environmental conditions. I collected 84 lettuce entries, 14 soybean, 49 sweet potato, 16 wheat, 237 white potato, and 26 mix crop entries. The list will grow with the publication of new research. This database will be integrated with a search and systems analysis computer program that will cross-reference multiple parameters to determine optimum edible yield under varying parameters. Also, we have made preliminary effort to put together a crop handbook for BIO-Plex plant growth management. It will be a collection of information obtained from experts who provided recommendations on a particular crop's growing conditions. It includes bibliographic, environmental, nutrient solution, potential yield, harvest nutritional, and propagation procedure information. This handbook will stand as the baseline growth conditions for the first set of experiments in the BIO-Plex facility.

    Thermo-mechanical contributions to pellet–clad interaction (PCI) in advanced gas-cooled reactors (AGRs) are modelled in the ABAQUS finite element (FE) code. User supplied sub-routines permit the modelling of the non-linear behaviour of AGR fuel through life. Through utilisation of ABAQUS’s well-developed pre- and post-processing ability, the behaviour of the axially constrained steel clad fuel was modelled. The 2D axisymmetric model includes thermo-mechanical behaviour of the fuel with time and condition dependent material properties. Pellet cladding gap dynamics and thermal behaviour are also modelled. The model treats heat up as a fully coupled temperature-displacement study. Dwell time and direct power cycling was applied to model the impact of online refuelling, a key feature of the AGR. The model includes the visco-plastic behaviour of the fuel under the stress and irradiation conditions within an AGR core and a non-linear heat transfer model. A multiscale fission gas release model is applied to compute pin pressure; this model is coupled to the PCI gap model through an explicit fission gas inventory code. Whole pin, whole life, models are able to show the impact of the fuel on all segments of cladding including weld end caps and cladding pellet locking mechanisms (unique to AGR fuel). The development of this model in a commercial FE package shows that the development of a potentially verified and future-proof fuel performance code can be created and used

    Numerous advanced techniques have been evaluated and tested at EBR-2 as part of a plant-life extension program for detection of degradation and other abnormalities in plant systems. Two techniques have been determined to be of considerable assistance in planning for the extended-life operation of EBR-2. The first, a computer-based pattern-recognition system (System State Analyzer or SSA) is used for surveillance of the primary system instrumentation, primary sodium pumps and plant heat balances. This surveillance has indicated that the SSA can detect instrumentation degradation and system performance degradation over varying time intervals and can be used to provide derived signal values to replace signals from failed sensors. The second technique, also a computer-based pattern-recognition system (Sequential Probability Ratio Test or SPRT) is used to validate signals and to detect incipient failures in sensors and components or systems. It is being used on the failed fuel detection system and is experimentally used on the primary coolant pumps. Both techniques are described and experience with their operation presented

    The aim of this quantitative, cross-sectional study was to identify barriers and facilitators to end-of-life communication experienced by family caregivers of patients with advanced chronic organ failure and to examine agreement in barriers and facilitators between family caregivers and patients. Patients and family caregivers were interviewed using the barriers and facilitators questionnaire. Agreement was determined using intraclass correlation coefficients for continuous variables and Cohen's kappa for categorical variables. A total of 158 patients and family caregiver dyads were included. The most important barriers for family caregivers were related to uncertainty about expected care and focus on staying alive instead of dying. The facilitators were related to trust in and competence of their physician and earlier experiences with death in their (social) environment. For most barriers and facilitators, agreement between patients and family caregivers was fair to moderate. Differences in barriers and facilitators between patients and family caregivers ask for an individual approach to facilitate end-of-life communication.

    To develop an advanced long-life SMR core concept, the feasibility of the long-life breed-and-burn core concept has been assessed and the preliminary selection on the reactor design requirement such as fuel form, coolant material has been performed. With the simplified cigar-type geometry of 8m-tall CANDLE reactor concept, it has demonstrated the strengths of breed-and-burn strategy. There is a saturation region in the graph for the multiplication factors, which means that a steady breeding is being proceeded along the axial direction. The propagation behavior of the CANDLE core can be also confirmed through the evolution of the axial power profile. Coolant material is expected to have low melting point, density, viscosity and absorption cross section and a high boiling point, specific heat, and thermal conductivity. In this respect, sodium is preferable material for a coolant of this nuclear power plant system. The metallic fuel has harder spectrum compared to the oxide and carbide fuel, which is favorable to increase the breeding and extend the cycle length.

    The infrared gas transducer used during extravehicular activity (EVA) in the extravehicular mobility unit (EMU) measures and reports the concentration of carbon dioxide (CO2) in the ventilation loop. It is nearing its end of life and there are a limited number remaining. Meanwhile, the next generation advanced portable life support system (PLSS) now being developed requires CO2 sensing technology with performance beyond that presently in use. A laser diode (LD) spectrometer based on wavelength modulation spectroscopy (WMS) is being developed to address both applications by Vista Photonics, Inc. Accommodation within space suits demands that optical sensors meet stringent size, weight, and power requirements. Version 1.0 devices were delivered to NASA Johnson Space Center (JSC) in 2011. The sensors incorporate a laser diode based CO2 channel that also includes an incidental water vapor (humidity) measurement. The prototypes are controlled digitally with a field-programmable gate array (FPGA)/microcontroller architecture. Version 2.0 devices with improved electronics and significantly reduced wetted volumes were delivered to JSC in 2012. A version 2.5 upgrade recently implemented wavelength stabilized operation, better humidity measurement, and much faster data analysis/reporting. A wholly reconfigured version 3.0 will maintain the demonstrated performance of earlier versions while being backwards compatible with the EMU and offering a radiation tolerant architecture.

  17. Requirements Development Issues for Advanced Life Support Systems: Solid Waste Management

    Levri, Julie A.; Fisher, John W.; Alazraki, Michael P.; Hogan, John A.

    2002-01-01

    Long duration missions pose substantial new challenges for solid waste management in Advanced Life Support (ALS) systems. These possibly include storing large volumes of waste material in a safe manner, rendering wastes stable or sterilized for extended periods of time, and/or processing wastes for recovery of vital resources. This is further complicated because future missions remain ill-defined with respect to waste stream quantity, composition and generation schedule. Without definitive knowledge of this information, development of requirements is hampered. Additionally, even if waste streams were well characterized, other operational and processing needs require clarification (e.g. resource recovery requirements, planetary protection constraints). Therefore, the development of solid waste management (SWM) subsystem requirements for long duration space missions is an inherently uncertain, complex and iterative process. The intent of this paper is to address some of the difficulties in writing requirements for missions that are not completely defined. This paper discusses an approach and motivation for ALS SWM requirements development, the characteristics of effective requirements, and the presence of those characteristics in requirements that are developed for uncertain missions. Associated drivers for life support system technological capability are also presented. A general means of requirements forecasting is discussed, including successive modification of requirements and the need to consider requirements integration among subsystems.

    The current management of open pneumothorax (OPTX) is based on Advanced Trauma Life Support (ATLS) recommendations and consists of the application of a three-way occlusive dressing, followed by intercostal chest drain insertion. Very little is known regarding the spectrum and outcome of this approach, especially in the civilian setting. We conducted a retrospective review of 58 consecutive patients with OPTX over a four-year period managed in a high volume metropolitan trauma service in South Africa. Of the 58 patients included, 95% (55/58) were male, and the mean age for all patients was 21 years. Ninety-seven percent of all injuries were inflicted by knives and the remaining 3% (2/58) of injuries were inflicted by unknown weapons. 59% of injuries were left sided. In six patients (10%) a protocol violation was present in their management. Five of the six patients (83%) in whom protocol violation occurred developed a life-threatening event (tension PTX) compared to none amongst those where the protocol was followed (p < 0.001). There was no mortality as a direct result of management of OPTX following ATLS recommendations. ATLS recommendations for OPTX are safe and effective. Any deviation from this standard practice is associated with avoidable morbidity and potential mortality.

    The Advanced Life Support (ALS) Program has recently accelerated an effort to develop an On-line Project Information System (OPIS) for research project and technology development data centralization and sharing. There has been significant advancement in the On-line Project Information System (OPIS) over the past year (Hogan et al, 2004). This paper presents the resultant OPIS development approach. OPIS is being built as an application framework consisting of an uderlying Linux/Apache/MySQL/PHP (LAMP) stack, and supporting class libraries that provides database abstraction and automatic code generation, simplifying the ongoing development and maintenance process. Such a development approach allows for quick adaptation to serve multiple Programs, although initial deployment is for an ALS module. OPIS core functionality will involve a Web-based annual solicitation of project and technology data directly from ALS Principal Investigators (PIs) through customized data collection forms. Data provided by PIs will be reviewed by a Technical Task Monitor (TTM) before posting the information to OPIS for ALS Community viewing via the Web. Such Annual Reports will be permanent, citable references within OPIS. OPlS core functionality will also include Project Home Sites, which will allow PIS to provide updated technology information to the Community in between Annual Report updates. All data will be stored in an object-oriented relational database, created in MySQL(Reistered Trademark) and located on a secure server at NASA Ames Research Center (ARC). Upon launch, OPlS can be utilized by Managers to identify research and technology development (R&TD) gaps and to assess task performance. Analysts can employ OPlS to obtain the current, comprehensive, accurate information about advanced technologies that is required to perform trade studies of various life support system options. ALS researchers and technology developers can use OPlS to achieve an improved understanding of the NASA

    Severely-debilitating or life-threatening (SDLT) diseases include conditions in which life expectancy is short or quality of life is greatly diminished despite available therapies. As such, the medical context for SDLT diseases is comparable to advanced cancer and the benefit vs. risk assessment and development of SDLT disease therapeutics should be similar to that of advanced cancer therapeutics. A streamlined development approach would allow patients with SDLT conditions earlier access to therapeutics and increase the speed of progression through development. In addition, this will likely increase the SDLT disease therapeutic pipeline, directly benefiting patients and reducing the economic and societal burden of SDLT conditions. Using advanced-stage heart failure (HF) as an example that illustrates the concepts applicable to other SDLT indications, this article proposes a streamlined development paradigm for SDLT disease therapeutics and recommends development of aligned global regulatory guidance. © 2017 American Society for Clinical Pharmacology and Therapeutics.

    Most out-of-hospital cardiac arrests receiving emergency medical services in the United States are treated by ambulance service providers trained in advanced life support (ALS), but supporting evidence for the use of ALS over basic life support (BLS) is limited. To compare the effects of BLS and ALS on outcomes after out-of-hospital cardiac arrest. Observational cohort study of a nationally representative sample of traditional Medicare beneficiaries from nonrural counties who experienced out-of-hospital cardiac arrest between January 1, 2009, and October 2, 2011, and for whom ALS or BLS ambulance services were billed to Medicare (31,292 ALS cases and 1643 BLS cases). Propensity score methods were used to compare the effects of ALS and BLS on patient survival, neurological performance, and medical spending after cardiac arrest. Survival to hospital discharge, to 30 days, and to 90 days; neurological performance; and incremental medical spending per additional survivor to 1 year. Survival to hospital discharge was greater among patients receiving BLS (13.1% vs 9.2% for ALS; 4.0 [95% CI, 2.3-5.7] percentage point difference), as was survival to 90 days (8.0% vs 5.4% for ALS; 2.6 [95% CI, 1.2-4.0] percentage point difference). Basic life support was associated with better neurological functioning among hospitalized patients (21.8% vs 44.8% with poor neurological functioning for ALS; 23.0 [95% CI, 18.6-27.4] percentage point difference). Incremental medical spending per additional survivor to 1 year for BLS relative to ALS was $154,333. Patients with out-of-hospital cardiac arrest who received BLS had higher survival at hospital discharge and at 90 days compared with those who received ALS and were less likely to experience poor neurological functioning.

    Cancer patients frequently experience malnutrition and this is an important factor in impaired quality of life. This cross-sectional study examined the association between global quality of life and its various subscales with nutritional status among 61 (33 females and 28 males) advanced cancer patients cared for by selected hospices in peninsular Malaysia. The Patient Generated-Subjective Global Assessment (PG-SGA) and the Hospice Quality of Life Index (HQLI) were used to assess nutritional status and quality of life, respectively. Nine (14.7%) patients were well-nourished, 32 (52.5%) were moderately or suspected of being malnourished while 20 (32.8%) of them were severely malnourished. The total HQLI mean score for these patients was 189.9-/+51.7, with possible scores ranging from 0 to 280. The most problem areas in these patients were in the domain of functional well-being and the least problems were found in the social/spiritual domain. PG-SGA scores significantly correlated with total quality of life scores (r2= 0.38, pnutritional status exhibited a lower quality of life. Advanced cancer patients with poor nutritional status have a diminished quality of life. These findings suggest that there is a need for a comprehensive nutritional intervention for improving nutritional status and quality of life in terminally ill cancer patients under hospice care.

  3. Liquid fuels from Canadian coals

    1979-06-15

    In Canadian energy planning, the central issue of security of supply must be addressed by developing flexible energy systems that make the best possible use of available resources. For liquid fuel production, oil sands and heavy oil currently appear more attractive than coal or biomass as alternatives to conventional crude oil, but the magnitude of their economic advantage is uncertain. The existence of large resources of oil sands, heavy oils, natural gas and low-sulfur coals in Western Canada creates a unique opportunity for Canadians to optimize the yield from these resources and develop new technology. Many variations on the three basic liquefaction routes - hydroliquefaction, pyrolysis and synthesis - are under investigation around the world, and the technology is advancing rapidly. Each process has merit under certain circumstances. Surface-mineable subbituminous and lignite coals of Alberta and Saskatchewan appear to offer the best combination of favorable properties, deposit size and mining cost, but other deposits in Alberta, Nova Scotia and British Columbia should not be ruled out. The research effort in Canada is small by world standards, but it is unlikely that technology could be imported that is ideally suited to Canadian conditions. Importing technology is undesirable: innovation or process modification to suit Canadian coals and markets is preferred; coprocessing of coal liquids with bitumen or heavy oils would be a uniquely Canadian, exportable technology. The cost of synthetic crude from coal in Canada is uncertain, estimates ranging from $113 to $220/m/sup 3/ ($18 to $35/bbl). Existing economic evaluations vary widely depending on assumptions, and can be misleading. Product quality is an important consideration.

    To describe parent perspectives regarding the end-of-life experience of children with advanced heart disease. Cross-sectional multicenter survey study of bereaved parents. Two tertiary care pediatric hospitals. Parents of children younger than 21 years with primary cardiac diagnoses who died in the hospital 9 months to 4 years before the survey date. Parents were excluded if they were non-English speakers or had previously denied permission to contact. The Survey for Caring for Children with Advanced Heart Disease was developed, piloted, and then sent to parents of all children who died at two sites. Fifty bereaved parents responded (39% response rate) a mean of 2.7 years after their child's death. Median age at death was 6 months (3.6 d to 20.4 yr). At end-of-life, 86% of children were intubated and 46% were receiving mechanical circulatory support. Seventy-eight percent died during withdrawal of life-sustaining interventions and 16% during resuscitative efforts. Parents realized that their child had no realistic chance of survival a median of 2 days prior to death (0-30 d). According to parents, 47% of children suffered "a great deal," "a lot," or "somewhat" during the end-of-life period. The symptoms parents perceived to be causing the most suffering were breathing and feeding difficulties in children under 2 years and fatigue and sleeping difficulties in older children. Seventy-one percent of parents described the quality of life of their child during the last month of life as "poor" or "fair." Most parents (84%) described the quality of care delivered as "very good" or "excellent." According to their parents, many children with advanced heart disease experience suffering in the end-of-life care period. For most, realization that their child has no realistic chance of survival does not occur until late, some not until death is imminent. Once this realization occurs, however, parents perceive peacefulness, a "good death," and excellent quality of care

    Purpose: Existing studies that examine the effect of neoadjuvant chemoradiation (CRT) for locally advanced rectal cancer on patient quality of life (QOL) are limited. Our goals were to prospectively explore acute changes in patient-reported QOL endpoints during and after treatment and to establish a distribution of scores that could be used for comparison as new treatment modalities emerge. Methods and Materials: Fifty patients with locally advanced rectal cancer were prospectively enrolled at 2 institutions. Validated cancer-specific European Organization for Research and Treatment of Cancer (EORTC QLQ-CR30) and colorectal cancer-specific (EORTC QLQ-CR38 and EORTC QLQ-CR 29) QOL questionnaires were administered to patients 1 month before they began CRT, at week 4 of CRT, and 1 month after they had finished CRT. The questionnaires included multiple symptom scales, functional domains, and a composite global QOL score. Additionally, a toxicity scale was completed by providers 1 month before the beginning of CRT, weekly during treatment, and 1 month after the end of CRT. Results: Global QOL showed a statistically significant and borderline clinically significant decrease during CRT (-9.50, P=.0024) but returned to baseline 1 month after the end of treatment (-0.33, P=.9205). Symptoms during treatment were mostly gastrointestinal (nausea/vomiting +9.94, P<.0001; and diarrhea +16.67, P=.0022), urinary (dysuria +13.33, P<.0001; and frequency +11.82, P=.0006) or fatigue (+16.22, P<.0001). These symptoms returned to baseline after therapy. However, sexual enjoyment (P=.0236) and sexual function (P=.0047) remained persistently diminished after therapy. Conclusions: Rectal cancer patients undergoing neoadjuvant CRT may experience a reduction in global QOL along with significant gastrointestinal and genitourinary symptoms during treatment. Moreover, provider-rated toxicity scales may not fully capture this decrease in patient-reported QOL. Although most symptoms are transient

    Quality of life is a key component of cancer care; however, the factors that determine quality of life are not well understood. The aim of this study was to examine the relationship between quality of life parameters, performance status (PS), and the systemic inflammatory response in patients with advanced cancer. An international biobank of patients with advanced cancer was analyzed. Quality of life was assessed at a single time point by using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-C30). PS was assessed by using the Eastern Cooperative Oncology Group (ECOG) classification. Systemic inflammation was assessed by using the modified Glasgow Prognostic Score (mGPS), which combines C-reactive protein and albumin. The relationship between quality of life parameters, ECOG PS, and the mGPS was examined. Data were available for 2,520 patients, and the most common cancers were GI (585 patients [22.2%]) and pulmonary (443 patients [17.6%]). The median survival was 4.25 months (interquartile range, 1.36 to 12.9 months). Increasing mGPS (systemic inflammation) and deteriorating PS were associated with deterioration in quality-of-life parameters (P quality-of-life parameters independent of PS. Systemic inflammation was associated with quality-of-life parameters independent of PS in patients with advanced cancer. Further investigation of these relationships in longitudinal studies and investigations of possible effects of attenuating systemic inflammation are now warranted. © 2016 by American Society of Clinical Oncology.

    CANDU power reactor fuel has demonstrated an enviable operational record. More than 99.9% of the bundles irradiated have provided defect-free service. Defect excursions are responsible for the majority of reported defects. In some cases research and development effort is necessary to resolve these problems. In addition, development initiatives are also directed at improvements of the current design or reduction of fueling cost. The majority of the funding for this effort has been provided by COG (CANDU Owners' Group) over the past 10 to 15 years. This paper contains an overview of some key fuel technology programs within COG. The CANDU reactor is unique among the world's power reactors in its flexibility and its ability to use a number of different fuel cycles. An active program of analysis and development, to demonstrate the viability of different fuel cycles in CANDU, has been funded by AECL in parallel with the work on the natural uranium cycle. Market forces and advances in technology have obliged us to reassess and refocus some parts of our effort in this area, and significant success has been achieved in integrating all the Canadian efforts in this area. This paper contains a brief summary of some key components of the advanced fuel cycle program. (Author) 4 figs., tab., 18 refs

    Standard external cardiopulmonary resuscitation (SECPR) frequently produces very low perfusion pressures, which are inadequate to achieve restoration of spontaneous circulation (ROSC) and intact survival, particularly when the heart is diseased. Ultra-advanced life support (UALS) techniques may allow support of vital organ systems until either the heart recovers or cardiac repair or replacement is performed. Closed-chest emergency cardiopulmonary bypass (CPB) provides control of blood flow, pressure, composition and temperature, but has so far been applied relatively late. This additional low-flow time may preclude conscious survival. An easy, quick method for vessel access and a small preprimed system that could be taken into the field are needed. Open-chest CPR (OCCPR) is physiologically superior to SECPR, but has also been initiated too late in prior studies. Its application in the field has recently proven feasible. Variations of OCCPR, which deserve clinical trials inside and outside hospitals, include 'minimally invasive direct cardiac massage' (MIDCM), using a pocket-size plunger-like device inserted via a small incision and 'direct mechanical ventricular actuation' (DMVA), using a machine that pneumatically drives a cup placed around the heart. Other novel UALS approaches for further research include the use of an aortic balloon catheter to improve coronary and cerebral blood flow during SECPR, aortic flush techniques and a double-balloon aortic catheter that could allow separate perfusion (and cooling) of the heart, brain and viscera for optimal resuscitation of each. Decision-making, initiation of UALS methods and diagnostic evaluations must be rapid to maximize the potential for ROSC and facilitate decision-making regarding long-term circulatory support versus withdrawal of life support for hopeless cases. Research and development of UALS techniques needs to be coordinated with cerebral resuscitation research.

    To determine the functional disabilities and overall quality of life of patients operated for advanced (Stages III-IV) or recurrent squamous cell carcinomas (SCCA) after radiation therapy of the (pharyngo)larynx. From 1984 to 1997, 135 patients were consecutively treated for SCCA of the (pharyngo)larynx. There were 118 men and 17 women with a mean age of 60 years. The University of Washington QOL questionnaire (UW-QOL) (Deleyiannis et al) was administered to 19 long term survivors. Self-administered scale consisting of nine domains affected by treatment for head and neck cancer: pain, physical appareance, global activity, entertainement, employment, chewing, swallowing, speech and shoulder function. For each patient, a total score and weighted score were determined. Descriptive statistics were used. 9/19 patients reported that compared with one year prior to the diagnosis of cancer their general health was the same. Pain resolved in 78%; the physical appearance was juged not modified in 52% of the cases. Chewing and swallowing functions were respected in 94% of the cases. These functions were considered as very important in 53% and 68% respectively. Five patients are still at work; 11 patients retired. Work was considered as very important for 9/19 patients. Speech rehabilitation permitted a modified but well understandable communication in 63% of the cases. This function was considered by 88% of the patients as very important. Finally, 73% of the patients (14/19) reported having a good to excellent overall QOL. Though disabling, pharyngolaryngectomies do not necessarily translate into worse overall QOL; ultimate disabilities are widely variable. Many factors such family, friends, personal leisure, activities, employement, cultural habits were important and depending on each patient in enjoyement of life's estimation.

    Interdisciplinary tumor board decisions improve the quality of oncological therapies, while no such boards exist for end-of-life (EOL) decisions. The aim of this study was to assess the willingness of hemato-oncological and palliative care professionals to develop and participate in EOL boards. An aim of an EOL board would be to establish an interdisciplinary and comprehensive care for the remaining lifetime of patients suffering from advanced incurable diseases. Staff from the interdisciplinary teams of all hemato-oncological and palliative care wards in Vienna were invited to anonymously participate in an online survey. 309 professionals responded. 91% respondents reported a need to establish an EOL board, 63% expressed their willingness to actively participate in an EOL board, and 25% were indecisive. Regarding patient presence, 50% voted for an EOL board in the presence of the patients, and 36% voted for an EOL board in the absence of the patients. 95% had the opinion that an EOL board could improve patient care in the last phase of life. 64% stated that the development of an EOL board would be worthwhile, while 28% did not see enough resources available at their institutions. Regarding the desired type of documentation, 61% voted for a centrally available EOL decision, and 31% supported an in-house-based documentation. 94% voted for the availability of an information folder about EOL care. The willingness of professionals to establish an EOL board was very high. Further steps should be taken to implement such boards to improve EOL care.

    Currently, intensive care medicine strives to define a generally accepted way of dealing with end-of-life decisions, therapy limitation and therapy discontinuation.In 2006 a new advance directive legislation was enacted in Austria. Patients may now document their personal views regarding extension of treatment. The aim of this survey was to explore Austrian intensive care physicians' experiences with and their acceptance of the new advance directive legislation two years after enactment (2008). Under the aegis of the OEGARI (Austrian Society of Anaesthesiology, Resuscitation and Intensive Care) an anonymised questionnaire was sent to the medical directors of all intensive care units in Austria. The questions focused on the physicians' experiences regarding advance directives and their level of knowledge about the underlying legislation. There were 241 questionnaires sent and 139 were turned, which was a response rate of 58%. About one third of the responders reported having had no experience with advance directives and only 9 directors of intensive care units had dealt with more than 10 advance directives in the previous two years. Life-supporting measures, resuscitation, and mechanical ventilation were the predominantly refused therapies, wishes were mainly expressed concerning pain therapy. A response rate of almost 60% proves the great interest of intensive care professionals in making patient-oriented end-of-life decisions. However, as long as patients do not make use of their right of co-determination, the enactment of the new law can be considered only a first important step forward.

    The use of virtual reality (VR) training tools for medical education could lead to improvements in the skills of clinicians while providing economic incentives for healthcare institutions. The use of VR tools can also mitigate some of the drawbacks currently associated with providing medical training in a traditional clinical environment such as scheduling conflicts and the need for specialized equipment (e.g., high-fidelity manikins). This paper presents the details of the framework and the development methodology associated with a VR-based training simulator for advanced cardiac life support, a time critical, team-based medical scenario. In addition, we also report the key findings of a usability study conducted to assess the efficacy of various features of this VR simulator through a postuse questionnaire administered to various care providers. The usability questionnaires were completed by two groups that used two different versions of the VR simulator. One version consisted of the VR trainer with it all its features and a minified version with certain immersive features disabled. We found an increase in usability scores from the minified group to the full VR group.

    This paper examines mission simulation as an approach to develop requirements for automation and robotics for Advanced Life Support Systems (ALSS). The focus is on requirements and applications for command and control, control and monitoring, situation assessment and response, diagnosis and recovery, adaptive planning and scheduling, and other automation applications in addition to mechanized equipment and robotics applications to reduce the excessive human labor requirements to operate and maintain an ALSS. Based on principles of systems engineering, an approach is proposed to assess requirements for automation and robotics using mission simulation tools. First, the story of a simulated mission is defined in terms of processes with attendant types of resources needed, including options for use of automation and robotic systems. Next, systems dynamics models are used in simulation to reveal the implications for selected resource allocation schemes in terms of resources required to complete operational tasks. The simulations not only help establish ALSS design criteria, but also may offer guidance to ALSS research efforts by identifying gaps in knowledge about procedures and/or biophysical processes. Simulations of a planned one-year mission with 4 crewmembers in a Human Rated Test Facility are presented as an approach to evaluation of mission feasibility and definition of automation and robotics requirements.

    Since appropriate and time-table methods in trauma care have an important impact on patients'outcome, we evaluated the effect of Advanced Trauma Life Support (ATLS) program on medical interns' performance in simulated trauma patient management. A descriptive and analytical study before and after the training was conducted on 24 randomly selected undergraduate medical interns from Imam Reza Hospital in Mashhad, Iran. On the first day, we assessed interns' clinical knowledge and their practical skill performance in confronting simulated trauma patients. After 2 days of ATLS training, we performed the same study and evaluated their score again on the fourth day. The two findings, pre- and post- ATLS periods, were compared through SPSS version 15.0 software. P values less than 0.05 were considered statistically significant. Our findings showed that interns'ability in all the three tasks improved after the training course. On the fourth day after training, there was a statistically significant increase in interns' clinical knowledge of ATLS procedures, the sequence of procedures and skill performance in trauma situations (P less than 0.001, P equal to 0.016 and P equal to 0.01 respectively). ATLS course has an important role in increasing clinical knowledge and practical skill performance of trauma care in medical interns.

    Out-of-hospital emergency physicians in Austria need mandatory emergency physician training, followed by biennial refresher courses. Currently, both standardized ERC advanced life support (ALS) provider courses and conventional refresher courses are offered. This study aimed to compare the retention of ALS-knowledge of out-of-hospital emergency physicians depending on whether they had or had not participated in an ERC-ALS provider course since 2005. Participants (n=807) from 19 refresher courses for out-of-hospital emergency physicians answered eight multiple-choice questions (MCQ) about ALS based on the 2005 ERC guidelines. The pass score was 75% correct answers. A multivariate logistic regression analyzed differences in passing scores between those who had previously participated in an ERC-ALS provider course and those who had not. Age, gender, regularity of working as an out-of-hospital emergency physician and the self-reported number of real resuscitation efforts within the last 6months were entered as control variables. Out-of-hospital emergency physicians who had previously attended an ERC-ALS provider course had a significantly higher chance of passing the MCQ test (OR=1.60, p=0.015). Younger age (OR=0.95, pERC-ALS provider course since 2005 had a higher retention of ALS knowledge compared to non-ERC-ALS course participants. Copyright © 2011 Elsevier Ireland Ltd.

    We present a conceptual framework for coupling sensing to crop models for closed-loop analysis of plant production for NASA's program in advanced life support. Crop status may be monitored through non-destructive observations, while models may be independently applied to crop production planning and decision support. To achieve coupling, environmental variables and observations are linked to mode inputs and outputs, and monitoring results compared with model predictions of plant growth and development. The information thus provided may be useful in diagnosing problems with the plant growth system, or as a feedback to the model for evaluation of plant scheduling and potential yield. In this paper, we demonstrate this coupling using machine vision sensing of canopy height and top projected canopy area, and the CROPGRO crop growth model. Model simulations and scenarios are used for illustration. We also compare model predictions of the machine vision variables with data from soybean experiments conducted at New Jersey Agriculture Experiment Station Horticulture Greenhouse Facility, Rutgers University. Model simulations produce reasonable agreement with the available data, supporting our illustration.

    Interprofessional education (IPE) was investigated in the context of an evaluation of the Advanced Life Support in Obstetrics (ALSO) course in Australia. Our objectives were to examine doctors' and midwives' perceptions regarding interprofessional learning and measure changes in self-reported confidence in specific interprofessional clinical situations. A prospective, mixed methods design was used to survey 165 ALSO course participants before the course and 6 weeks after the course (n=101). Quantitative data were analysed using the Wilcoxon signed rank test, and all P levels lower than .05 were considered significant. Qualitative data were analyzed using content analysis. There were significant increases in midwives' confidence in all four aspects of interprofessional interaction measured 6 weeks following the course. However, the doctors only reported a significant increase in one aspect, the confidence that their clinical decisions were respected by the midwives with whom they worked. The qualitative data demonstrated an appreciation of different professional approaches to clinical situations and the importance of teamwork, communication, respect, and understanding. While most participants were positive about the advantages of IPE, just under half also believed there were some disadvantages, particularly due to the variable learning needs of individual professionals. Both doctors and midwives reported various benefits from IPE, and many believed that IPE assisted maternity team collaboration and communication in the workplace. However, educators need to skillfully manage IPE sessions to ensure a similar distribution of learning and that opportunities for discussion are equivalent for all individuals and professional groups.

    Maintenance of crew health is of paramount importance for long duration space missions. Weight loss, bone and calcium loss, increased exposure to radiation and oxidative stress are critical concerns that need to be alleviated. Tilapia are currently under evaluation as a source of food and their contribution to reducing waste in advanced life support systems (ALSS). The nutritional composition of tilapia whole bodies, fillet, and carcass residues were quantitatively determined. Carbon and nitrogen free-extract percentages were similar among whole body (53.76% and 6.96%, respectively), fillets (47.06% and 6.75%, respectively), and carcass (56.36% and 7.04%, respectively) whereas percentages of N, S, and protein were highest in fillet (13.34, 1.34, and 83.37%, respectively) than whole body (9.27, 0.62, and 57.97%, respectively) and carcass (7.70, 0.39, and 48.15%, respectively). Whole body and fillet meet and/or exceeded current nutritional recommendations for protein, vitamin D, ascorbic acid, and selenium for international space station missions. Whole body appears to be a better source of lipids and n-3 fatty acids, calcium, and phosphorous than fillet. Consuming whole fish appears to optimize equivalent system mass compared to consumption of fillets. Additional research is needed to determine nutritional composition of tilapia whole body, fillet, and carcass when fed waste residues possibly encountered in an ALSS.

    Systems engineering (SE) discipline has revolutionized the way engineers and managers think about solving issues related to design of complex systems: With continued development of state-of-the-art technologies, systems are becoming more complex and therefore, a systematic approach is essential to control and manage their integrated design and development. This complexity is driven from integration issues. In this case, subsystems must interact with one another in order to achieve integration objectives, and also achieve the overall system's required performance. Systems engineering process addresses these issues at multiple levels. It is a technology and management process dedicated to controlling all aspects of system life cycle to assure integration at all levels. The Advanced Integration Matrix (AIM) project serves as the systems engineering and integration function for the Human Support Technology (HST) program. AIM provides means for integrated test facilities and personnel for performance trade studies, analyses, integrated models, test results, and validated requirements of the integration of HST. The goal of AIM is to address systems-level integration issues for exploration missions. It will use an incremental systems integration approach to yield technologies, baselines for further development, and possible breakthrough concepts in the areas of technological and organizational interfaces, total information flow, system wide controls, technical synergism, mission operations protocols and procedures, and human-machine interfaces.

    The aim of this study is to estimate the feasibility of quality of life (QOL) research and to evaluate the QOL prospectively in locally advanced prostate cancer patients treated with hormonal treatment combined with radiotherapy. The treatment schedule was that patients with decreasing prostatic specific antigen (PSA) levels below 10 ng/ml after receiving 6 months of neoadjuvant hormonal treatment were randomly divided into two groups; one group was the continuous hormonal treatment group and the other was the intermittent hormonal treatment group. Both groups received a total dose of 72 Gy external beam radiotherapy with concomitant hormonal treatment followed by 6 months of adjuvant hormonal treatment following radiotherapy. At 14 months, patients either underwent continuous or intermittent hormonal treatment according to the random allocation. QOL was assessed at baseline, and at 6, 8, 14, and 20 months after treatment using functional assessment of cancer treatment-general (FACT-G), P with the other 3 items comprising bother of urination, bother of bowel movement, and bother of sexual activity. Between January 2000 and June 2003, a total of 188 patients were enrolled in this study. The rate of collection of baseline QOL sheets was 98.0%. The rate of answer to questions of QOL sheets was 99.0%. At baseline, the average score of FACT-G, P was 120.7 and the maximum score was more than twice the minimum score. Dysfunction of urination and bowel movement was correlated with the bother of urination and bowel movement, respectively. On the other hand, dysfunction of sexual activity was not correlated with the bother of sexual activity. In June 2003, all of the QOL sheets at baseline, and at 6, 8, and 14 months were completely collected from a total of 72 patients. Although QOL at 8 months was significantly affected compared with QOL at baseline and at 6 months, QOL at 14 months was significantly improved compared with that at 8 months and there was no significant

    Purpose: Existing studies that examine the effect of neoadjuvant chemoradiation (CRT) for locally advanced rectal cancer on patient quality of life (QOL) are limited. Our goals were to prospectively explore acute changes in patient-reported QOL endpoints during and after treatment and to establish a distribution of scores that could be used for comparison as new treatment modalities emerge. Methods and Materials: Fifty patients with locally advanced rectal cancer were prospectively enrolled at 2 institutions. Validated cancer-specific European Organization for Research and Treatment of Cancer (EORTC QLQ-CR30) and colorectal cancer-specific (EORTC QLQ-CR38 and EORTC QLQ-CR 29) QOL questionnaires were administered to patients 1 month before they began CRT, at week 4 of CRT, and 1 month after they had finished CRT. The questionnaires included multiple symptom scales, functional domains, and a composite global QOL score. Additionally, a toxicity scale was completed by providers 1 month before the beginning of CRT, weekly during treatment, and 1 month after the end of CRT. Results: Global QOL showed a statistically significant and borderline clinically significant decrease during CRT (−9.50, P=.0024) but returned to baseline 1 month after the end of treatment (−0.33, P=.9205). Symptoms during treatment were mostly gastrointestinal (nausea/vomiting +9.94, P<.0001; and diarrhea +16.67, P=.0022), urinary (dysuria +13.33, P<.0001; and frequency +11.82, P=.0006) or fatigue (+16.22, P<.0001). These symptoms returned to baseline after therapy. However, sexual enjoyment (P=.0236) and sexual function (P=.0047) remained persistently diminished after therapy. Conclusions: Rectal cancer patients undergoing neoadjuvant CRT may experience a reduction in global QOL along with significant gastrointestinal and genitourinary symptoms during treatment. Moreover, provider-rated toxicity scales may not fully capture this decrease in patient-reported QOL. Although most symptoms are

    The Canadian Astronomy Data Centre (CADC) is the world's largest astronomical data center, holding over 0.5 Petabytes of information, and serving nearly 3000 astronomers worldwide. Its current data collections include BLAST, CFHT, CGPS, FUSE, Gemini, HST, JCMT, MACHO, MOST, and numerous other archives and services. It provides extensive data archiving, curation, and processing expertise, via projects such as MegaPipe, and enables substantial day-to-day collaboration between resident astronomers and computer specialists. It is a stable, powerful, persistent, and properly supported environment for the storage and processing of large volumes of data, a condition that is now absolutely vital for their science potential to be exploited by the community. Through initiatives such as the Common Archive Observation Model (CAOM), the Canadian Virtual Observatory (CVO), and the Canadian Advanced Network for Astronomical Research (CANFAR), the CADC is at the global forefront of advancing astronomical research through improved data services. The CAOM aims to provide homogeneous data access, and hence viable interoperability between a potentially unlimited number of different data collections, at many wavelengths. It is active in the definition of numerous emerging standards within the International Virtual Observatory, and several datasets are already available. The CANFAR project is an initiative to make cloud computing for storage and data-intensive processing available to the community. It does this via a Virtual Machine environment that is equivalent to managing a local desktop. Several groups are already processing science data. CADC is also at the forefront of advanced astronomical data analysis, driven by the science requirements of astronomers both locally and further afield. The emergence of 'Astroinformatics' promises to provide not only utility items like object classifications, but to directly enable new science by accessing previously undiscovered or intractable

    To assess the educational efficacy of a Web-based pediatric advanced life support course (Web-PALS). Nonrandomized, prospective, cohort study. University medical center. Health care providers (includes physicians, nurses, paramedics, and respiratory therapists) taking either the Web-PALS or a traditional PALS course (Trad-PALS). Web-PALS. Postcourse written examination scores and scored videotapes of students performing 5 PALS procedures were compared between study groups. Students completed precourse and postcourse questionnaires, rating on a 5-point Likert scale their self-confidence to perform PALS assessments and procedures. A structured, course satisfaction survey was given after students had taken the Web-PALS course. Eighty-six students completed the study (44 Web-PALS and 42 Trad-PALS). All students achieved a passing score on the written examination on their first attempt. Compared with students in the Trad-PALS group, students in the Web-PALS group scored slightly lower (97.1% vs 95.4%; difference, 1.7%; 95% confidence interval, 0.1-3.2). Mean overall videotape scores were similar among the Web-PALS and Trad-PALS groups (75.0% vs 73.0%; difference, 2.0%; 95% confidence interval, -2.0 to 6.0). After completing the Web-PALS course, the mean level of confidence improved from 3.77 to 4.28 (difference, 0.51; 95% confidence interval, 0.33-0.69). Ninety-six percent of respondents indicated that Web-PALS met all of the stated objectives of the PALS course. All respondents indicated that they would recommend Web-PALS to a colleague. Students perceive Web-PALS as a positive educational experience. Though not identical to students taking the Trad-PALS course, they performed well on postcourse cognitive and psychomotor testing. These findings support Web-PALS as an acceptable format for administering the PALS course.

    Assessing advanced life support (ALS) competence requires validated instruments. Existing instruments include aspects of technical skills (TS), non-technical skills (NTS) or both, but one instrument for detailed assessment that suits all resuscitation situations is lacking. This study aimed to develop an instrument for the evaluation of the overall ALS performance of the whole team. This instrument development study had four phases. First, we reviewed literature and resuscitation guidelines to explore items to include in the instrument. Thereafter, we interviewed resuscitation team professionals (n = 66), using the critical incident technique, to determine possible additional aspects associated with the performance of ALS. Second, we developed an instrument based on the findings. Third, we used an expert panel (n = 20) to assess the validity of the developed instrument. Finally, we revised the instrument based on the experts' comments and tested it with six experts who evaluated 22 video recorded resuscitations. The final version of the developed instrument had 69 items divided into adherence to guidelines (28 items), clinical decision-making (5 items), workload management (12 items), team behaviour (8 items), information management (6 items), patient integrity and consideration of laymen (4 items) and work routines (6 items). The Cronbach's α values were good, and strong correlations between the overall performance and the instrument were observed. The instrument may be useful for detailed assessment of the team's overall performance, but the numerous items make the use demanding. The instrument is still under development, and more research is needed to determine its psychometric properties. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

    The overall objective of this three-year grant is to provide NASA Langley's System Analysis Branch with improved affordability tools and methods based on probabilistic cost assessment techniques. In order to accomplish this objective, the Aerospace Systems Design Laboratory (ASDL) needs to pursue more detailed affordability, technology impact, and risk prediction methods and to demonstrate them on variety of advanced commercial transports. The affordability assessment, which is a cornerstone of ASDL methods, relies on the Aircraft Life Cycle Cost Analysis (ALCCA) program originally developed by NASA Ames Research Center and enhanced by ASDL. This grant proposed to improve ALCCA in support of the project objective by updating the research, design, test, and evaluation cost module, as well as the engine development cost module. Investigations into enhancements to ALCCA include improved engine development cost, process based costing, supportability cost, and system reliability with airline loss of revenue for system downtime. A probabilistic, stand-alone version of ALCCA/FLOPS will also be developed under this grant in order to capture the uncertainty involved in technology assessments. FLOPS (FLight Optimization System program) is an aircraft synthesis and sizing code developed by NASA Langley Research Center. This probabilistic version of the coupled program will be used within a Technology Impact Forecasting (TIF) method to determine what types of technologies would have to be infused in a system in order to meet customer requirements. A probabilistic analysis of the CER's (cost estimating relationships) within ALCCA will also be carried out under this contract in order to gain some insight as to the most influential costs and the impact that code fidelity could have on future RDS (Robust Design Simulation) studies.

    An ongoing effort is underway at NASA Ames Research Center (ARC) to develop an On-line Project Information System (OPIS) for the Advanced Life Support (ALS) Program. The objective of this three-year project is to develop, test, revise and deploy OPIS to enhance the quality of decision-making metrics and attainment of Program goals through improved knowledge sharing. OPIS will centrally locate detailed project information solicited from investigators on an annual basis and make it readily accessible by the ALS Community via a Web-accessible interface. The data will be stored in an object-oriented relational database (created in MySQL) located on a secure server at NASA ARC. OPE will simultaneously serve several functions, including being an research and technology development (R&TD) status information hub that can potentially serve as the primary annual reporting mechanism for ALS-funded projects. Using OPIS, ALS managers and element leads will be able to carry out informed R&TD investment decisions, and allow analysts to perform accurate systems evaluations. Additionally, the range and specificity of information solicited will serve to educate technology developers of programmatic needs. OPIS will collect comprehensive information from all ALS projects as well as highly detailed information specific to technology development in each ALS area (Waste, Water, Air, Biomass, Food, Thermal, Controls and Systems Analysis). Because the scope of needed information can vary dramatically between areas, element-specific technology information is being compiled with the aid of multiple specialized working groups. This paper presents the current development status in terms of the architecture and functionality of OPIS. Possible implementation approaches for OPIS are also discussed.

    2013-01-01

    Although well established for the treatment of certain hematologic malignancies, maintenance therapy has only recently become a treatment paradigm for advanced non–small-cell lung cancer. Maintenance therapy, which is designed to prolong a clinically favorable state after completion of a predefined number of induction chemotherapy cycles, has two principal paradigms. Continuation maintenance therapy entails the ongoing administration of a component of the initial chemotherapy regimen, generally the nonplatinum cytotoxic drug or a molecular targeted agent. With switch maintenance (also known as sequential therapy), a new and potentially non–cross-resistant agent is introduced immediately on completion of first-line chemotherapy. Potential rationales for maintenance therapy include increased exposure to effective therapies, decreasing chemotherapy resistance, optimizing efficacy of chemotherapeutic agents, antiangiogenic effects, and altering antitumor immunity. To date, switch maintenance therapy strategies with pemetrexed and erlotinib have demonstrated improved overall survival, resulting in US Food and Drug Administration approval for this indication. Recently, continuation maintenance with pemetrexed was found to prolong overall survival as well. Factors predicting benefit from maintenance chemotherapy include the degree of response to first-line therapy, performance status, the likelihood of receiving further therapy at the time of progression, and tumor histology and molecular characteristics. Several aspects of maintenance therapy have raised considerable debate in the thoracic oncology community, including clinical trial end points, the prevalence of second-line chemotherapy administration, the role of treatment-free intervals, quality of life, economic considerations, and whether progression-free survival is a worthy therapeutic goal in this disease setting.

    Scientific ground-truth measurements for near-term Mars missions, such as the 2009 Mars Science Laboratory (MSL) mission, are essential for validating current in situ flight instrumentation and for the development of advanced instrumentation technologies for life-detection missions over the next decade. The NASA Astrobiology Institute (NAI) has recently funded a consortium of researchers called the Astrobiology Sample Analysis Program (ASAP) to analyze an identical set of homogenized martian analog materials in a "round-robin" style using both state-of-the-art laboratory techniques as well as in-situ flight instrumentation including the SAM gas chromatograph mass spectrometer and CHEMIN X-ray diffraction/fluorescence instruments on MSL and the Urey and MOMA organic analyzer instruments under development for the 2013 ExoMars missions. The analog samples studied included an Atacama Desert soil from Chile, the Murchison meteorite, a gypsum sample from the 2007 AMASE Mars analog site, jarosite from Panoche Valley, CA, a hydrothermal sample from Rio Tinto, Spain, and a "blind" sample collected during the 2007 MSL slow-motion field test in New Mexico. Each sample was distributed to the team for analysis to: (1) determine the nature and inventory of organic compounds, (2) measure the bulk carbon and nitrogen isotopic composition, (3) investigate elemental abundances, mineralogy and matrix, and (4) search for biological activity. The experimental results obtained from the ASAP Mars analog research consortium will be used to build a framework for understanding the biogeochemistry of martian analogs, help calibrate current spaceflight instrumentation, and enhance the scientific return from upcoming missions.

    End-of-life decision making is value-laden within the context of culture and bioethics. Also, ethics committee role is difficult to understand on this, thus need for ethnomethodological perspective in an expanding bioethical age. Anthropological approach was utilized to document Yoruba definition and perspective of death, cultural beliefs about end-of-life decision making, factors influencing it and ethics committee role. Interviews were conducted among selected Yoruba resident in Akinyele LGA, Oyo State, Nigeria. Content analytical approach was used for data analysis. Yoruba culture, death is socially constructed having spiritual, physical and social significance. Relationship between the dying and significant others influences decision making. Hierarchy of authority informs implementing traditional advance directive. Socialization, gender, patriarchy, religious belief and tradition are major considerations in end-of-life decision making. Awareness, resource allocation and advocacy are important ethics committees' roles. Further research into cultural diversity of end-of-life decision making will strengthen ethical practice in health care delivery.

    CELSS Antarctic Analog Project (CAAP) represents a logical solution to the multiple objectives of both the NASA and the National Science Foundation (NSF). CAAP will result in direct transfer of proven technologies and systems, proven under the most rigorous of conditions, to the NSF and to society at large. This project goes beyond, as it must, the generally accepted scope of CELSS and life support systems including the issues of power generation, human dynamics, community systems, and training. CAAP provides a vivid and starkly realistic testbed of Controlled Ecological Life Support System (CELSS) and life support systems and methods. CAAP will also be critical in the development and validation of performance parameters for future advanced life support systems.

    Discussion: Pre-hospital acute pain management in the Western Cape does not appear to conform to best practice as Advanced Life Support providers in the Western Cape use low doses of morphine. Chest pain is an important reason for drug administration in acute pre-hospital pain. Multimodal analgesia is not a feature of care in this pre-hospital service. The development of a Clinical Practice Guideline for and training in pre-hospital pain should be viewed as imperative.

    Many patients near death report an interest in knowing their prognoses. Patients' awareness of disease status may lead to more appropriate care and maintained or improved quality of life. However, it is not known whether advanced cancer patients' awareness of disease status is associated with patients' quality of life. We aimed to examine the effect of patients' awareness of disease status on the health-related quality of life (HRQOL) among advanced cancer patients undergoing palliative chemotherapy. In this prospective cohort study, patients were followed-up at 4-6 weeks and 2-3 months after the initial palliative chemotherapy. Patients' awareness of disease status, and demographic and clinical characteristics were assessed at baseline, and depression and anxiety using the Hospital Anxiety and Depression Scale (HADS) and HRQOL using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) were assessed three times. In total, 100 patients with advanced cancer starting palliative chemotherapy were recruited from two tertiary university hospitals and from the Korea National Cancer Center. Patients with advanced cancer undergoing palliative chemotherapy experienced deteriorated HRQOL. Of these, the patients who were aware of their disease status as incurable had significantly higher role (p=0.002), emotional (p=0.025), and social functioning (p=0.002), and lower fatigue (p=0.008), appetite loss (p=0.039), constipation (p=0.032), financial difficulties (p=0.019), and anxiety (p=0.041) compared with patients unaware of disease status. Our findings demonstrate the importance of patients' awareness of disease status to HRQOL.

    The aim of this study was to evaluate whether socioemotional stress affects the quality of cardiopulmonary resuscitation during advanced life support in a simulated manikin model. A randomized crossover trial with advanced life support performed in two different conditions, with and without exposure to socioemotional stress. The study was conducted at the Stavanger Acute Medicine Foundation for Education and Research simulation center, Stavanger, Norway. Paramedic teams, each consisting of two paramedics and one assistant, employed at Stavanger University Hospital, Stavanger, Norway. A total of 19 paramedic teams performed advanced life support twice in a randomized fashion, one control condition without socioemotional stress and one experimental condition with exposure to socioemotional stress. The socioemotional stress consisted of an upset friend of the simulated patient who was a physician, spoke a foreign language, was unfamiliar with current Norwegian resuscitation guidelines, supplied irrelevant clinical information, and repeatedly made doubts about the paramedics' resuscitation efforts. Aural distractions were supplied by television and cell telephone. The primary outcome was the quality of cardiopulmonary resuscitation: chest compression depth, chest compression rate, time without chest compressions (no-flow ratio), and ventilation rate after endotracheal intubation. As a secondary outcome, the socioemotional stress impact was evaluated through the paramedics' subjective workload, frustration, and feeling of realism. There were no significant differences in chest compression depth (39 vs. 38 mm, p = .214), compression rate (113 vs. 116 min⁻¹, p = .065), no-flow ratio (0.15 vs. 0.15, p = .618), or ventilation rate (8.2 vs. 7.7 min⁻¹, p = .120) between the two conditions. There was a significant increase in the subjective workload, frustration, and feeling of realism when the paramedics were exposed to socioemotional stress. In this advanced life

    Symptom clusters in advanced cancer can influence patient outcomes. There is large heterogeneity in the methods used to identify symptom clusters. To investigate the consistency of symptom cluster composition in advanced cancer patients using different statistical methodologies for all patients across five primary cancer sites, and to examine which clusters predict functional status, a global assessment of health and global quality of life. Principal component analysis and exploratory factor analysis (with different rotation and factor selection methods) and hierarchical cluster analysis (with different linkage and similarity measures) were used on a data set of 1562 advanced cancer patients who completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Core 30. Four clusters consistently formed for many of the methods and cancer sites: tense-worry-irritable-depressed (emotional cluster), fatigue-pain, nausea-vomiting, and concentration-memory (cognitive cluster). The emotional cluster was a stronger predictor of overall quality of life than the other clusters. Fatigue-pain was a stronger predictor of overall health than the other clusters. The cognitive cluster and fatigue-pain predicted physical functioning, role functioning, and social functioning. The four identified symptom clusters were consistent across statistical methods and cancer types, although there were some noteworthy differences. Statistical derivation of symptom clusters is in need of greater methodological guidance. A psychosocial pathway in the management of symptom clusters may improve quality of life. Biological mechanisms underpinning symptom clusters need to be delineated by future research. A framework for evidence-based screening, assessment, treatment, and follow-up of symptom clusters in advanced cancer is essential.

    Full Text Available Abstract Background Currently, intensive care medicine strives to define a generally accepted way of dealing with end-of-life decisions, therapy limitation and therapy discontinuation. In 2006 a new advance directive legislation was enacted in Austria. Patients may now document their personal views regarding extension of treatment. The aim of this survey was to explore Austrian intensive care physicians' experiences with and their acceptance of the new advance directive legislation two years after enactment (2008. Methods Under the aegis of the OEGARI (Austrian Society of Anaesthesiology, Resuscitation and Intensive Care an anonymised questionnaire was sent to the medical directors of all intensive care units in Austria. The questions focused on the physicians' experiences regarding advance directives and their level of knowledge about the underlying legislation. Results There were 241 questionnaires sent and 139 were turned, which was a response rate of 58%. About one third of the responders reported having had no experience with advance directives and only 9 directors of intensive care units had dealt with more than 10 advance directives in the previous two years. Life-supporting measures, resuscitation, and mechanical ventilation were the predominantly refused therapies, wishes were mainly expressed concerning pain therapy. Conclusion A response rate of almost 60% proves the great interest of intensive care professionals in making patient-oriented end-of-life decisions. However, as long as patients do not make use of their right of co-determination, the enactment of the new law can be considered only a first important step forward.

  7. The Need for Technology Maturity of Any Advanced Capability to Achieve Better Life Cycle Cost (LCC)

    Programs such as space transportation systems are developed and deployed only rarely, and they have long development schedules and large development and life cycle costs (LCC). They have not historically had their LCC predicted well and have only had an effort to control the DDT&E phase of the programs. One of the factors driving the predictability, and thus control, of the LCC of a program is the maturity of the technologies incorporated in the program. If the technologies incorporated are less mature (as measured by their Technology Readiness Level - TRL), then the LCC not only increases but the degree of increase is difficult to predict. Consequently, new programs avoid incorporating technologies unless they are quite mature, generally TRL greater than or equal to 7 (system prototype demonstrated in a space environment) to allow better predictability of the DDT&E phase costs unless there is no alternative. On the other hand, technology development programs rarely develop technologies beyond TRL 6 (system/subsystem model or prototype demonstrated in a relevant environment). Currently the lack of development funds beyond TRL 6 and the major funding required for full scale development leave little or no funding available to prototype TRL 6 concepts so that hardware would be in the ready mode for safe, reliable and cost effective incorporation. The net effect is that each new program either incorporates little new technology or has longer development schedules and costs, and higher LCC, than planned. This paper presents methods to ensure that advanced technologies are incorporated into future programs while providing a greater accuracy of predicting their LCC. One method is having a dedicated organization to develop X-series vehicles or separate prototypes carried on other vehicles. The question of whether such an organization should be independent of NASA and/or have an independent funding source is discussed. Other methods are also discussed. How to make the

    The electrochemical reduction of carbon dioxide (CO2) using ceramic oxygen generators (COGs) is well known and widely studied, however, conventional devices using yttria-stabilized zirconia (YSZ) electrolytes operate at temperatures greater than 700 C. Operating at such high temperatures increases system mass compared to lower temperature systems because of increased energy overhead to get the COG up to operating temperature and the need for heavier insulation and/or heat exchangers to reduce the COG oxygen (O2) output temperature for comfortable inhalation. Recently, the University of Florida developed novel ceramic oxygen generators employing a bilayer electrolyte of gadolinia-doped ceria and erbia-stabilized bismuth for NASA's future exploration of Mars. To reduce landed mass and operation expenditures during the mission, in-situ resource utilization was proposed using these COGs to obtain both lifesupporting oxygen and oxidant/propellant fuel, by converting CO2 from the Mars atmosphere. The results showed that oxygen could be reliably produced from CO2 at temperatures as low as 400 C. These results indicate that this technology could be adapted to CO2 removal from a spacesuit and other applications in which CO2 removal was an issue. The strategy proposed for CO2 removal for advanced life support systems employs a catalytic layer combined with a COG so that it is reduced all the way to solid carbon and oxygen. Hence, a three-phased approach was used for the development of a viable low weight COG for CO2 removal. First, to reduce the COG operating temperature a high oxide ion conductivity electrolyte was developed. Second, to promote full CO2 reduction while avoiding the problem of carbon deposition on the COG cathode, novel cathodes and a removable catalytic carbon deposition layer were designed. Third, to improve efficiency, a pre-stage for CO2 absorption was used to concentrate CO2 from the exhalate before sending it to the COG. These subsystems were then

    Advanced Cardiac Life Support (ACLS) is a series of team-based, sequential and time constrained interventions, requiring effective communication and coordination of activities that are performed by the care provider team on a patient undergoing cardiac arrest or respiratory failure. The state-of-the-art ACLS training is conducted in a face-to-face environment under expert supervision and suffers from several drawbacks including conflicting care provider schedules and high cost of training equipment. The major objective of the study is to describe, including the design, implementation, and evaluation of a novel approach of delivering ACLS training to care providers using the proposed virtual reality simulator that can overcome the challenges and drawbacks imposed by the traditional face-to-face training method. We compare the efficacy and performance outcomes associated with traditional ACLS training with the proposed novel approach of using a virtual reality (VR) based ACLS training simulator. One hundred and forty-eight (148) ACLS certified clinicians, translating into 26 care provider teams, were enrolled for this study. Each team was randomly assigned to one of the three treatment groups: control (traditional ACLS training), persuasive (VR ACLS training with comprehensive feedback components), or minimally persuasive (VR ACLS training with limited feedback components). The teams were tested across two different ACLS procedures that vary in the degree of task complexity: ventricular fibrillation or tachycardia (VFib/VTach) and pulseless electric activity (PEA). The difference in performance between control and persuasive groups was not statistically significant (P=.37 for PEA and P=.1 for VFib/VTach). However, the difference in performance between control and minimally persuasive groups was significant (P=.05 for PEA and P=.02 for VFib/VTach). The pre-post comparison of performances of the groups showed that control (P=.017 for PEA, P=.01 for VFib/VTach) and

    Full Text Available INTRODUCTION The incidence of patients presenting with advanced pelvic malignancy with obstructive uropathy is high in our country. Relentless progress of the malignancy will cause deterioration of renal function, aggravation of pain, infection, deterioration of Quality of Life (QOL, uremia and death. Decreased renal function is considered as a contraindication for palliative chemo and radiotherapy. However urinary diversion in these patients will lead to improvement in renal function and may help in administration of palliative therapy and thus, improve the quality of life of these patients. MATERIALS AND METHODS The present study includes the obstructive uropathy patients secondary to pelvic malignancy referred to our institution for urinary diversion between Jan 2010 to Dec 2014. Total 40 patients were included, of which, 25 patients underwent PCN, 9 patients retrograde DJ stenting, 4 patients refused the treatment, 2 patients were not fit for any intervention due to coagulopathy & comorbid conditions. Of 34 treated patients, 30 were female patients and 4 were male patients. All the patients were explained about the procedure and proper consent taken. Laboratory investigations like CBC, coagulation profile, LFT, routine urine analysis, urine C&S and serum electrolytes were carried out. Haemodialysis was done for 10 patients whose serum creatinine was >6mg% & potassium >6meq. USG guided PCN insertion was done in 8 patients, and in those who failed in this procedure, fluoroscopic C-ARM guided PCN insertion done in 17 patients. Post operatively RFT and serum electrolytes were assessed on 3, 7, 15, & 30th day. PCN catheter was changed once in 3 months. RESULTS 8 patients succeeded in USG guided PCN insertion and 17 patients who failed USG PCN insertion, was done under C–Arm guidance. 3 patients received blood transfusion. No deaths were seen during or post procedure in the hospital. Renal functions improved and normalised in most of the

    To assess which laboratory and clinical factors are associated with fatigue in patients with terminal cancer. We evaluated 51 patients with advanced incurable solid tumors using the Chalder Fatigue Questionnaire (CFQ) and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale for fatigue; the Pittsburgh Sleep Quality Index (PSQI-BR) for sleep quality; the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression; the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire, Version 3.0 (QLQ C-30); and Functional Assessment of Cancer Therapy (FACT) for quality of life. We also analyzed several inflammatory markers and the modified Glasgow prognostic score (mGPS). We observed severe fatigue in 19 (38%) patients (FACIT-F score >36). There was a significant correlation between fatigue as evaluated by the CFQ and quality of sleep and between the CFQ mental fatigue subscale scores and TNF-α level. When fatigue was evaluated using the FACIT-F scale, we observed a significant association between fatigue and anxiety/depression, quality of sleep, mGPS, and hemoglobin levels. Fatigue measured both with the CFQ and FACIT-F scale correlated with poor quality of life according to the EORTC QLQ C-30. In patients with advanced cancer, fatigue is a common symptom associated with the presence of inflammation, poor quality of sleep, depression/anxiety, and poor quality of life. © The Author(s) 2015.

    Dementia will become more common as the population ages. Advanced dementia should be considered as a terminal illnesses and end-of-life (EOL) care is very much needed for this disease group. Currently, the EOL services provided to this vulnerable group in Hong Kong, especially those living in residential care homes, is limited. The usual practice of residential care homes is to send older residents with advanced dementia to acute hospitals when they are sick, irrespective of their wish, premorbid status, diagnoses and prognosis. This may not accord with what the patients perceive to be a "good death". There are many barriers for older people to die in place, both at home and at the residential care home. In the community, to enhance EOL care to residential care home for the elderly (RCHE) residents, pilot EOL program had been carried out by some Community Geriatric Assessment Teams. Since 2015, the Hospital Authority funded program "Enhance Community Geriatric Assessment Team Support to End-of-life Patients in Residential Care Homes for the Elderly" has been started. In the program, advance care planning (ACP), Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) (non-hospitalized) order will be established and the program will be expected to cover all clusters in Hong Kong by 2018/2019. In hospital setting, EOL clinical plan and EOL ward in geriatric step-down hospitals may be able to improve the quality of death of older patients. In Sep 2015, the Hospital Authority Guidelines on Life-Sustaining Treatment in the Terminally Ill was updated. Amongst other key EOL issues, careful (comfort) hand feeding was mentioned in the guideline. Other new developments include the possible establishment of enduring power of attorney for health care decision and enhancement of careful hand feeding amongst advanced dementia patients in RCHEs.

    The aims were to describe symptoms and health-related quality of life (HRQoL) in Greenlandic patients with advanced cancer and to assess the applicability and internal consistency of the Greenlandic version of the EORTC-QLQ-C30 core version 3.0. A Greenlandic version of the EORTC QLQ-C30 v.3.0 was developed. The translation process included independent forward translation, reconciliation and independent back translation by native Greenlandic-speaking translators who were fluent in English. After pilot testing, a population-based cross-sectional study of patients with advanced cancer receiving palliative treatment was conducted. Internal consistency was examined by calculating Cronbach's alpha coefficients for five function scales and three symptom scales. Of the 58 patients who participated in the study, 47% had reduced social functioning, 36% had reduced physical and role functioning and 19% had reduced emotional and cognitive functioning. Furthermore, 48% reported fatigue, and 33% reported financial problems. The Greenlandic version of the EORTC had good applicability in the assessment of symptoms and quality of life. Acceptable Cronbach's alpha coefficients (above 0.70) were observed for the physical, role and social functioning scales, the fatigue scale and the global health status scale. Patients with undergoing palliative treatment in Greenland for advanced cancer reported high levels of social and financial problems and reduced physical functioning. This indicates a potential for improving palliative care service and increasing the focus on symptom management. The Greenlandic version of the EORTC-QLQ-C30 represents an applicable and reliable tool to describe symptoms and health-related quality of life among Greenlandic patients with advanced cancer.

  15. Life cycle environmental impacts of advanced wastewater treatment techniques for removal of pharmaceuticals and personal care products (PPCPs).

    Science.gov (United States)

    Zepon Tarpani, Raphael Ricardo; Azapagic, Adisa

    2018-06-01

    Pharmaceutical and personal care products (PPCPs) are of increasing interest because of their ecotoxicological properties and environmental impacts. Wastewater treatment plants (WWTPs) are the main pathway for their release into freshwaters due to the inefficiency of conventional WWTPs in removing many of these contaminants from effluents. Therefore, different advanced effluent treatment techniques have been proposed for their treatment. However, it is not known at present how effective these treatment methods are and whether on a life cycle basis they cause other environmental impacts which may outweigh the benefits of the treatment. In an effort to provide an insight into this question, this paper considers life cycle environmental impacts of the following advanced treatment techniques aimed at reducing freshwater ecotoxicity potential of PPCPs: granular activated carbon (GAC), nanofiltration (NF), solar photo-Fenton (SPF) and ozonation. The results suggest that on average NF has the lowest impacts for 13 out of 18 categories considered. GAC is the best alternative for five impacts, including metals and water depletion, but it has the highest marine eutrophication. SPF and ozonation are the least sustainable for eight impacts, including ecotoxicity and climate change. GAC and NF are also more efficient in treating heavy metals while avoiding generation of harmful by-products during the treatment, thus being more suitable for potable reuse of wastewater. However, releasing the effluent without advanced treatment to agricultural land achieves a much higher reduction of freshwater ecotoxicity than treating it by any of the advanced treatments and releasing to the environment. Therefore, the use of advanced effluent treatment for agricultural purposes is not recommended. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Approximately 22,700 Canadian women were expected to be diagnosed with breast cancer in 2012. Despite improvements in screening and adjuvant treatment options, a substantial number of postmenopausal women with hormone receptor positive (hr+) breast cancer will continue to develop metastatic disease during or after adjuvant endocrine therapy. Guidance on the selection of endocrine therapy for patients with hr+ disease that is negative for the human epidermal growth factor receptor 2 (her2-) and that has relapsed or progressed on earlier nonsteroidal aromatase inhibitor (nsai) therapy is of increasing clinical importance. Exemestane, fulvestrant, and tamoxifen are approved therapeutic options in this context. Four phase iii trials involving 2876 patients-efect, sofea, confirm, and bolero-2-have assessed the efficacy of various treatment options in this clinical setting. Data from those trials suggest that standard-dose fulvestrant (250 mg monthly) and exemestane are of comparable efficacy, that doubling the dose of fulvestrant from 250 mg to 500 mg monthly results in a 15% reduction in the risk of progression, and that adding everolimus to exemestane (compared with exemestane alone) results in a 57% reduction in the risk of progression, albeit with increased toxicity. Multiple treatment options are now available to women with hr+ her2- advanced breast cancer recurring or progressing on earlier nsai therapy, although current clinical trial data suggest more robust clinical efficacy with everolimus plus exemestane. Consideration should be given to the patient's age, functional status, and comorbidities during selection of an endocrine therapy, and use of a proactive everolimus safety management strategy is encouraged.

In the last phase of life treatment decisions differ as they often put more emphasis on weighing quantity against quality of life, such as whether or not to start treatment aimed at life prolongation but with the possibility of side effects. This study aimed to obtain insight into cancer patients' preferences and the reasons for patients' preferred role in treatment decision-making at the end of life. 28 advanced cancer patients were included at the start of their first line treatment. In-depth interviews were held prior to upcoming treatment decisions whether or not to start a life prolonging treatment. The Control Preference Scale was used to start discussing the extent and type of influence patients wanted to have concerning upcoming treatment decision-making. Interviews were audio taped and transcribed. All patients wanted their physician to participate in the treatment decision-making process. The extent to which patients themselves preferred to participate seemed to depend on how patients saw their own role or assessed their own capabilities for participating in treatment decision-making. Patients foresaw a shift in the preferred level of participation to a more active role depending in the later phase of illness when life prolongation would become more limited and quality of life would become more important. Patients vary in how much involvement they would like to have in upcoming treatment decision-making. Individual patients' preferences may change in the course of the illness, with a shift to more active participation in the later phases. Communication about patients' expectations, wishes and preferences for participation in upcoming treatment decisions is of great importance. An approach in which these topics are openly discussed would be beneficial.

    In a large, multicenter, double-blind study of the effect of haloperidol and the atypical antipsychotic remoxipride on improvement of negative symptoms in schizophrenia, quality of life was also assessed using a modified version of the Sickness Impact Profile (SIP). Compared with previous studies, this study had a longer duration (28 weeks), and the dose of the comparator, haloperidol, was much lower. At the end of the study, compared with the baseline, both treatment groups reported comparable improvement in negative symptoms as defined by the protocol (at least 20% improvement). Similarly, both groups showed comparable changes on global and multidimensional self-assessments of quality of life. All the subfactors of the modified version of the SIP were similar in both groups, except for the subfactor that relates to alertness behavior, which possibly reflects remoxipride's lack of any sedating properties compared with haloperidol. This study presents an approach for inclusion of quality of life as an outcome measure in the design of clinical trials of new antipsychotic medications.

    Objective: To evaluate the influence of palliative intervention therapy on advanced gastrointestinal carcinoma patients with depression and anxiety before and after the treatment. Methods: 56 advanced gastrointestinal carcinoma patients were selected and treated with intra-arterial perfusion chemotherapy or intra-arterial perfusion chemotherapy with embolization. Curative effects were assessed with the SDS, SAS and FACT-G before and after the treatment. In addition, all patients took self-assessment with SCL-90, comparing with the Chinese norms. Results: SCL-90 scores including the somatization agent, depression agent, and anxiety agent scores of the advanced gastrointestinal carcinoma were higher than those of Chinese norms, with significant difference (P<0.05). After palliative intervention therapy, the scores of SDS and SAS were lower than those before the palliative intervention therapy with significant difference (P< 0.05); and furthermore with an obvious improvement in the scores of FACT-G (P<0.05). Conclusion: Palliative intervention therapy for advanced gastrointestinal carcinoma patients can improve the complaints of depression anxiety and quality of life. (authors)

    Patient autonomy is a primary value in US health care. It is assumed that patients want to be fully and directly informed about serious health conditions and want to engage in advance planning about medical care at the end-of-life. Written advance directives and proxy decision-makers are vehicles to promote autonomy when patients are no longer able to represent their wishes. Cross-cultural studies have raised questions about the universal acceptance of these health care values among all ethnicities. In the current investigation, Bosnian immigrants were interviewed about their views of physician-patient communication, advance directives, and locus of decision-making in serious illness. Many of the respondents indicated that they did not want to be directly informed of a serious illness. There was an expressed preference for physician- or family-based health care decisions. Advance directives and formally appointed proxies were typically seen as unnecessary and inconsistent with many respondents' personal values. The findings suggest that the value of individual autonomy and control over the health care decisions may not be applicable to cultures with a collectivist orientation.

    People with advanced lung cancer experience later symptoms after treatment that is related to poorer psychosocial and quality of life (QOL) outcomes. The purpose of this study was to identify the effect of symptom clusters and depression on the QOL of patients with advanced lung cancer. A sample of 178 patients with advanced lung cancer at the National Cancer Center in Korea completed a demographic questionnaire, the M.D. Anderson Symptom Inventory-Lung Cancer, the Center for Epidemiological Studies Depression Scale, and the Functional Assessment of Cancer Therapy-General scale. The most frequently experienced symptom was fatigue, anguish was the most severe symptom-associated distress, and 28.9% of participants were clinically depressed. Factor analysis was used to identify symptom clusters based on the severity of patients' symptom experiences. Three symptom clusters were identified: treatment-associated, lung cancer and psychological symptom clusters. The regression model found a significant negative impact on QOL for depression and lung cancer symptom cluster. Age as the control variable was found to be significant impact on QOL. Therefore, psychological screening and appropriate intervention is an essential part of advanced cancer care. Both pharmacological and non-pharmacological approaches for alleviating depression may help to improve the QOL of lung cancer patients. © 2016 John Wiley & Sons Ltd.

    High steam generators performance is a prerequisite for high plant availability and possible life time extension. During operation, the performance is reduced by fouling of the heating tubes and by corrosion, resulting on a reduction of the heat-exchange area. Such steam generator degradation problems arise from mechanical degradation and a continuous ingress of non-volatile contaminants, i.e. corrosion products and salt impurities accumulated in the steam generators. In addition, the tube scales in general affect the steam generator thermal performance, which ultimately cause a reduction of power output. AREVA applied an integrated service for utilities to evaluate all operational parameters influencing the steam generator performance. The evaluation is assisted by a systematic approach to evaluate the major steam generator operational data. The different data are structured and indexed in a Cleanling-Matrix. The result of this matrix is a quantified, dimensionless figure, given as the Fouling Index. The Fouling Index allows to monitor the condition of steam generators, compare it to other plants and, in combination with a life-time management applied at several German utilities, it allows verified statements on the past operation. Based on these data, an extrapolation of the potential additional life-time of the component is possible. As such, the Fouling Index is a valuable tool concerning life-time extension considerations. The application of the cleanliness criteria in combination with operational data with respect to life-time monitoring and improvements of steam generator performance are presented. (author)

    Quality of life concerns in patients with advanced diseases might be different from other patients and are shaped by sociocultural context. The objective of this qualitative study was to identify domains and themes of health-related quality of life (HRQoL) that Chinese patients with advanced cancer in Singapore considered relevant and important. English- and Chinese-speaking patients with advanced solid cancer were recruited from a tertiary cancer center and a community-based hospice for in-depth interview or focused group discussion. Thematic analysis was used to identify subthemes, themes, and domains from the transcripts. Forty-six ethnic Chinese (aged 26-86, 48% male) participated in the study. Six domains of HRQoL concerns were identified: pain and suffering, physical health, social health, mental health, financial well-being, and spiritual health. Pain and suffering are not limited to the physical domain, reflecting the multidimensional nature of this concept. Pain and suffering must also be understood within the cultural context. Healthcare relations (i.e., social health), existential well-being and religious well-being (i.e., spiritual health), and suffering (i.e., pain and suffering) are not fully captured in the existing HRQoL instruments. In addition, financial issues and the practice of secrecy in interpersonal relationships emerged as unique features possibly arising from our sociocultural context and healthcare financing landscape. Socioculturally specific issues not measured by the existing HRQoL instruments for use in patients with advanced cancers or terminal diseases were found in our study. These are non-physical pain and suffering, meaning of illness, meaning of death, financial issues, and practice of secrecy in interpersonal relationships.

    Life support system designs for long-duration space missions have a multitude of requirements drivers, such as mission objectives, political considerations, cost, crew wellness, inherent mission attributes, as well as many other influences. Evaluation of requirements satisfaction can be difficult, particularly at an early stage of mission design. Because launch cost is a critical factor and relatively easy to quantify, it is a point of focus in early mission design. The method used to determine launch cost influences the accuracy of the estimate. This paper discusses the appropriateness of dynamic mission simulation in estimating the launch cost of a life support system. This paper also provides an abbreviated example of a dynamic simulation life support model and possible ways in which such a model might be utilized for design improvement. c2004 COSPAR.

    In temperate urbanized areas where road salting is used for winter road maintenance, the level of chloride in surface waters has been increasing. While a number of studies have shown that the early-life stages of freshwater mussels are particularly sensitive to salt; few studies have examined the toxicity of salt-impacted winter road runoff to the early-life stages of freshwater mussels to confirm that chloride is the driver of toxicity in this mixture. This study examines the acute toxicity of field-collected winter road runoff to the glochidia of wavy-rayed lampmussels (Lampsilis fasciola) (48 h exposure) and newly released juvenile fatmucket mussels (Lampsilis siliquoidea) (road run-off created with moderately hard synthetic water (∼80 mg CaCO 3 /L) were 1177 (95% confidence interval (CI): 1011-1344 mg Cl - /L) and 2276 mg Cl - /L (95% CI: 1698-2854 mg Cl - /L), respectively. These effect concentrations correspond with the toxicity of chloride reported in other studies, indicating that chloride is likely the driver of toxicity in salt-impacted road-runoff, with other contaminants (e.g., metals, polycyclic aromatic hydrocarbons) playing a de minimis role. Toxicity data from the current study and literature and concentrations of chloride in the surface waters of Ontario were used to conduct a probabilistic risk assessment of chloride to early-life stage freshwater mussels. The assessment indicated that chronic exposure to elevated chloride levels could pose a risk to freshwater mussels; further investigation is warranted to ensure that the most sensitive organisms are protected.

  18. Canadian environmental sustainability indicators 2006

    International Nuclear Information System (INIS)

    2006-01-01

    In 2004, the Canadian government committed to reporting annual national indicators of air quality, greenhouse gas (GHG) emissions and freshwater quality in order to provide Canadians with more regular and consistent information on the state of the environment and how it is linked with human activities. The national air quality indicators in this report focused on human exposure to ground-level ozone and fine particulate matter (PM 2.5 ). The report showed that from 1990 to 2004, the ozone indicator showed year-to-year variability, with an averaged increase of 0.9 per cent per year. Stations in southern Ontario reported the highest levels of ozone and PM 2.5 in the country in 2004. There was no discernible upward or downward trend in PM 2.5 levels at the national level for the 2000 to 2004 period, and GHG emissions rose 27 per cent from 1990 to 2004. In 2004, emissions were 35 per cent above the target to which Canada committed under the Kyoto Protocol. However, while total emissions rose, emissions per unit of gross domestic product (GDP) fell by 14 per cent from 1990 to 2004. GHG emissions also grew faster than the Canadian population, resulting in a 10 per cent rise in emissions per person. The freshwater quality indicator presented in this report covered the period from 2002 to 2004, and focused on the ability of Canada's surface waters to support aquatic life. For the 340 sites selected across southern Canada, water quality was rated as good or excellent at 44 per cent of sites, fair at 34 per cent of sites, and marginal or poor at 22 per cent of sites. The report included a chapter which attempted to integrate the indicators with other environmental impacts, measures of economic performance, and indices of social progress to improve the ability of the report to influence decision-making that fully accounts for environmental sustainability. 63 refs., 18 figs

    Canadians' health and their social and economic well-being are fundamentally linked to the quality of their environment. Recognizing this, in 2004 the Government of Canada committed to establishing national indicators of freshwater quality, air quality and greenhouse gas emissions. The goal of these new indicators is to provide Canadians with more regular and reliable information on the state of their environment and how it is linked with human activity. Canadians need clearly defined environmental indicators - measuring sticks that can track the results that have been achieved through the efforts of governments, industries and individuals to protect and improve the environment. Environment Canada, Statistics Canada and Health Canada are working together to further develop and communicate these indicators. Reflecting the joint responsibility for environmental management in Canada, this effort has benefited from the cooperation and input of the provinces and territories. The indicators are: air quality; greenhouse gas emissions; and, freshwater quality. Air quality tracks Canadians' exposure to ground-level ozone - a key component of smog. The indicator measures one of the most common, harmful air pollutants to which people are exposed. The use of the seasonal average of ozone concentrations reflects the potential for long-term health effects. Greenhouse gas emissions tracks the annual releases of the six greenhouse gases that are the major contributors to climate change. The indicator comes directly from the greenhouse gas inventory report prepared by Environment Canada for the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. The data are widely used to report on progress toward Canada's Kyoto target for reduced emissions. Freshwater quality reports the status of surface water quality at selected monitoring sites across the country. For this first report, the focus of the indicator is on the protection of aquatic life, such as

    The number of people with dementia is growing at an alarming rate. An abundance of research over the past two decades has examined the complex aspects of caring for a relative with dementia. However, far less research has been conducted specific to the experiences of family caregivers providing end-of-life care, which is perplexing, as dementia is a terminal illness. This article presents what is known and highlights the gaps in the literature relevant to the experiences of family caregivers of persons with dementia at the end of life. A thorough search of the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PubMed databases from 1960 to 2011 was conducted. Ten studies were identified that specifically addressed the experience of family caregivers providing end-of-life care to a relative with advanced dementia. Common themes of these studies included: 1) the experience of grief, 2) guilt and burden with decision making, 3) how symptoms of depression may or may not be resolved with death of the care receiver, 4) how caregivers respond to the end-stage of dementia, and 5) expressed needs of family caregivers. It is evident from this literature review that much remains to be done to conceptualize the experience of end-of-life caregiving in dementia.

    One of the reasons for use of the lead or lead-bismuth alloy coolants is the high boiling temperature that avoids the possibility of coolant voiding. Also, these coolants are compatible with air, steam, and water. Therefore, intermediate coolant loop is not required as in the sodium cooled reactors 3. Lead is considered to be more attractive coolant than lead-bismuth alloy because of its higher availability, lower price, and much lower amount of polonium activity by factor of 104 relatively to lead. On the other hand, lead has higher melting temperature of 601K than that of lead-bismuth (398K), which narrows the operating temperature range and also leads to the possibility of freezing and blockage in fresh cores. Neutronically, the lead and lead-bismuth have very similar characteristics to each other. The lead-alloy coolants have lower moderating power and higher scattering without increasing moderation for neutrons below 0.5MeV, which reduces the leakage of the neutrons through the core and provides an excellent reflecting capability for neutrons. Due to the above features of lead or lead-alloy coolants, there have been lots of studies on the small lead cooled core designs. In this paper, small-safe long-life lead cooled reactor cores having high discharge burnup are designed and neutronically analyzed.. The cores considered in this work rates 110MWt (36.7MWe). In this work, the long-life with high discharge burnup was achieved by using thorium or depleted uranium blanket loaded in the central region of the core. Also, we considered a reference core having no blanket for the comparison. This paper provides the detailed neutronic analyses for these small long-life cores and the detailed analyses of the reactivity coefficients and the composition changes in blankets. The results of the core design and analyses show that our small long-life cores can be operated without refueling over their long-lives longer than 45EFPYs (Effective Full Power Year). In this work

    Recent focus on national standards within Australian hospitals has prompted a focus on the training of our staff in advanced life support (ALS). Research in critical care nursing has questioned the traditional annual certification of ALS competence as the best method of delivering this training. Simulation and team-based training may provide better ALS education to intensive care unit (ICU) staff. Our new inter-professional team-based advanced life support program involved ICU staff in a large private metropolitan ICU. A prospective observational study using three standardised questionnaires and two multiple choice questionnaire assessments was conducted. Ninety-nine staff demonstrated a 17.8% (95% confidence interval 4.2-31, P =0.01) increase in overall ICU nursing attendance at training sessions. Questionnaire response rates were 93 (94%), 99 (100%) and 60 (61%) respectively; 51 (52%) staff returned all three. Criteria were assessed by scores from 0 to 10. Nurses reported improved satisfaction with the education program (9.4 to 7.1, P versus 7.9 and 8.2, P versus 7.4 and 7.8, P versus 8.1, P =0.04). The new program cost approximately an extra $16,500 in nursing salaries. We concluded that team-based, inter-professional ALS training produced statistically significant improvements in nursing attendance, satisfaction with ALS education, confidence and role understanding compared to traditional ALS training.

    In our context, existential plight refers to heightened concerns about life and death when people are diagnosed with cancer. Although the duration of existential plight has been proposed to be approximately 100 days, evidence from longitudinal studies raises questions about whether the impact of a diagnosis of advanced cancer may require a longer period of adjustment. The purpose of our study was to examine spiritual well-being (SpWB) and quality of life (QoL) as well as their interrelationship in 52 patients with advanced cancer after 100 days since the diagnosis at one and three months post-baseline. The study was designed as a secondary data analysis of a cluster randomized clinical trial involving patients with stage 3 or 4 cancer undergoing treatment. SpWB was measured using the 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp-12); common factor analyses revealed a three-factor pattern on the FACIT-Sp-12. Quality of life was measured with the Functional Assessment of Cancer Therapy-General (FACT-G). We limited our sample to participants assigned to the control condition (n = 52). SpWB and QoL remained stable between one and three months post-baseline, which were a median of 112 and 183 days after diagnosis, respectively. SpWB was found to be associated with QoL more strongly than physical and emotional well-being. Peace and Meaning each contributed unique variance to QoL, and their relative importance shifted over time. Faith was positively related to QoL initially. This association became insignificant at three months post-baseline. This study underscores the significance of SpWB for people newly diagnosed with advanced cancer, and it highlights the dynamic pattern of Peace, Meaning, and Faith in association with QoL. Our results confirm that patients newly diagnosed with advanced cancer experience an existential crisis, improve and stabilize over time. Future studies with larger samples over a longer period of

    The success of long-duration missions will depend on resource recovery and the self-sustainability of life support technologies. Current technologies used on the International Space Station (ISS) utilize chemical and mechanical processes, such as filtration, to recover potable water from urine produced by crewmembers. Such technologies have significantly reduced the need for water resupply through closed-loop resource recovery and recycling. Harvesting the important components of urine requires selectivity, whether through the use of membranes or other physical barriers, or by chemical or biological processes. Given the chemical composition of urine, the downstream benefits of urine processing for resource recovery will be critical for many aspects of life support, such as food production and the synthesis of biofuels. This paper discusses the beneficial components of urine and their potential applications, and the challenges associated with using urine for nutrient recycling for space application.

    Full Text Available Background/Aim. Cancer, one of the leading causes of mortality in the world, imposes a substantial economic burden on each society, including Serbia. The aim of this study was to evaluate the major cancer cost drivers in Serbia. Methods. A retrospective, indepth, bottom-up analysis of two combined databases was performed in order to quantify relevant costs. End-of-life data were obtained from patients with cancer, who deceased within the first year of the established diagnose, including basic demographics, diagnosis, tumour histology, medical resource use and related costs, time and cause of death. All costs were allocated to one of the three categories of cancer health care services: primary care (included home care, hospital outpatient and hospital inpatient care. Results. Exactly 114 patients were analyzed, out of whom a high percent (48.25% had distant metastases at the moment of establishing the diagnosis. Malignant neoplasms of respiratory and intrathoracic organs were leading causes of morbidity. The average costs per patient were significantly different according to the diagnosis, with the highest (13,114.10 EUR and the lowest (4.00 EUR ones observed in the breast cancer and melanoma, respectively. The greatest impact on total costs was observed concerning pharmaceuticals, with 42% of share (monoclonal antibodies amounted to 34% of all medicines and 14% of total costs, followed by oncology medical care (21%, radiation therapy and interventional radiology (11%, surgery (9%, imaging diagnostics (9% and laboratory costs (8%. Conclusion. Cancer treatment incurs high costs, especially for end-of-life pharmaceutical expenses, ensued from medical personnel tendency to improve such patients’ quality of life in spite of nearing the end of life. Reimbursement policy on monoclonal antibodies, in particular at end-stage disease, should rely on cost-effectiveness evidence as well as documented clinical efficiency. [Projekat Ministarstva nauke

    The petroleum supply and demand balance was discussed and a comparison between Canadian and U.S. refineries was provided. The impact of changing product specifications on the petroleum industry was also discussed. The major changes include sulphur reductions in gasoline, benzene and MMT additives. These changes have been made in an effort to satisfy environmental needs. Geographic margin variations in refineries between east and west were reviewed. An overview of findings from the Solomon Refining Study of Canadian and American refineries, which has been very complimentary of the Canadian refining industry, was provided. From this writer's point of view refinery utilization has improved but there is a threat from increasing efficiency of US competitors. Environmental issues will continue to impact upon the industry and while the chances for making economic returns on investment are good for the years ahead, it will be a challenge to maintain profitability

Thirteen community-based medical oncology clinics across the midwestern United States. A convenience sample of 385 predominantly Caucasian women with advanced-stage breast cancer receiving chemotherapy and/or hormonal therapy. Following the baseline interview, women were randomized into three primary groups: reflexology (n = 95), lay foot manipulation (LFM) (n = 95), or conventional care (n = 96). Two preliminary reflexology (n = 51) and LFM (n = 48) test groups were used to establish the protocols. Participants were interviewed again postintervention at study weeks 5 and 11. Breast cancer-specific health-related quality of life (HRQOL), physical functioning, and symptoms. No adverse events were reported. A longitudinal comparison revealed significant improvements in physical functioning for the reflexology group compared to the control group (p = 0.04). Severity of dyspnea was reduced in the reflexology group compared to the control group (p Reflexology may be added to existing evidence-based supportive care to improve HRQOL for patients with advanced-stage breast cancer during chemotherapy and/or hormonal therapy. Reflexology can be recommended for safety and usefulness in relieving dyspnea and enhancing functional status among women with advanced-stage breast cancer.

    Palliative care is a multidisciplinary approach that focuses on the improvement of quality of life (QOL) of patients as well as their families. QOL research in palliative care has so far primarily focused on patients, but interest in the QOL of their relatives is increasing. For instruments measuring QOL in relatives, data on psychometric properties are often limited, and so far, none has been available in German. This study translates and validates the "Quality of Life in Life-Threatening Illness-Family Carer Version" (QOLLTI-F) in German-speaking carers of advanced cancer patients. The QOLLTI-F was translated from English into German according to the World Health Organisation's recommendations and validated in informal caregivers of terminally ill cancer patients of three Viennese hospitals. Hope was measured to assess concurrent validity; traumatic stress, anxiety, depression and subjective burden were measured to assess discriminant validity. Internal consistency, test-retest reliability and discriminative power were established. The scale's factor structure was explored using a set of factor analyses. Of the 308 caregivers participating in the study, 42 completed the QOLLTI-F retest after a mean of 5 days. The internal consistency was α = 0.85 for the overall scale, Pearson correlation between test and retest lay at r = 0.92. As expected, a significant positive correlation was found with hope (r = 0.40) and significant negative correlations with traumatic stress (r = -0.41), depression (r = -0.51), anxiety (r = -0.52) and overall subjective burden (r = -0.55). The original seven-factor structure was not reproduced, but the scale showed a stable four-factor structure with factors capturing (1) feelings about carers' own life, (2) professional care, (3) interaction with the patient and others and (3) carers' outlook on life. This study provides a sound translation and validation of the first QOL assessment tool for caregivers of

    Full Text Available Today monoclonal immunoglobulin gamma (IgG antibodies have become a major option in cancer therapy especially for the patients with advanced or metastatic cancers. Efficacy of monoclonal antibodies (mAbs are achieved through both its antigen binding fragment (Fab and crystallizable fragment (Fc. Fab can specifically recognize tumor associated antigen (TAA and thus modulate TAA-linked downstream signaling pathways that may lead to inhibition of tumor growth, induction of tumor apoptosis and differentiation. The Fc region can further improve mAbs’ efficacy by mediating effector functions such as antibody-dependent cellular cytotoxicity (ADCC, complement-dependent cytotoxicity (CDC and antibody dependent cell-mediated phagocytosis (ADCP. Moreover, Fc is the region interacting with the neonatal Fc receptor (FcRn in a pH-dependent manner that can slow down IgG’s degradation and extend its serum half-life. Loss of the antibody Fc region dramatically shortens its serum half-life and weakens its anti-cancer effects. Given the essential roles that the Fc region plays in the modulation of the efficacy of mAb in cancer treatment, Fc engineering has been extensively studied in the past years. This review focuses on the recent advances in therapeutic Fc engineering that modulates its related effector functions and serum half-life. We also discuss the progress made in aglycosylated mAb development that may substantially reduce cost of manufacture but maintain similar efficacies as conventional glycosylated mAb. Finally, we highlight several Fc engineering based mAbs under clinical trials.

    Full Text Available Many advanced vehicle technologies, including electric vehicles (EVs, hybrid electric vehicles (HEVs, and fuel cell vehicles (FCVs, are gaining attention throughout the World due to their capability to improve fuel efficiencies and emissions. When evaluating the operational successes of these new fuel-efficient vehicles, it is essential to consider energy usage and greenhouse gas (GHG emissions throughout the entire lifetimes of the vehicles, which are comprised of two independent cycles: a fuel cycle and a vehicle cycle. This paper intends to contribute to the assessment of the environmental impacts from the alternative technologies throughout the lifetimes of various advanced vehicles through objective comparisons. The methodology was applied to six commercial vehicles that are available in the U.S. and that have similar dimensions and performances. We also investigated the shifts in energy consumption and emissions through the use of electricity and drivers’ behavior regarding the frequencies of battery recharging for EVs and plug-in hybrid electric vehicles (PHEVs. This study thus gives insight into the impacts of the electricity grid on the total energy cycle of a vehicle lifetime. In addition, the total ownership costs of the selected vehicles were examined, including considerations of the fluctuating gasoline prices. The cost analysis provides a resource for drivers to identify optimal choices for their driving circumstances.

    One of the core values in terminal care the respect of patient 'autonomy'. This essay begins with a discussion of medical ethics principles and the Natural Death Act in Taiwan and then summarizes two medical ethical dilemmas, truth telling and advance care planning (ACP), faced in the development of hospice and palliative care in Taiwan. The terminal truth telling process incorporates the four basic principles of Assessment and preparation, Communication with family, Truth-telling process, and Support and follow up (the so-called "ACTs"). Many experts suggest practicing ACP by abiding by the following five steps: (1) presenting and illustrating topics; (2) facilitating a structured discussion; (3) completing documents with advanced directives (ADs); (4) reviewing and updating ADs; and (5) applying ADs in clinical circumstances. Finally, the myths and challenges in truth telling and ADs include the influence of healthcare system procedures and priorities, inadequate communication skills, and the psychological barriers of medical staffs. Good communication skills are critical to truth telling and ACP. Significant discussion about ACP should help engender mutual trust between patients and the medical staffs who take the time to establish such relationships. Promoting patient autonomy by providing the opportunity of a good death is an important goal of truth telling and ACP in which patients have opportunities to choose their terminal treatment.

  3. Invited commentary: integrating a life-course perspective and social theory to advance research on residential segregation and health.

    Research on racial residential segregation and health typically uses multilevel, population-based, slice-in-time data. Although research using this approach, including that by Kershaw et al. (Am J Epidemiol. 2013;177(4):299-309), has been valuable, I argue that to advance our understanding of how residential segregation influences health and health disparities, it is critical to incorporate a life-course perspective and integrate social theory. Applying a life-course perspective would entail modeling transitions, cumulative risk, and developmental and dynamic processes and mechanisms, as well as recognizing the contingency of contextual effects on different social groups. I discuss the need for analytic methods appropriate for modeling health effects of distal causes experienced across the life course, such as segregation, that operate through multiple levels and sequences of mediators, potentially across decades. Sociological theories of neighborhood attainment (e.g., segmented assimilation, ethnic resurgence, and place stratification theories) can guide effect-modification tests to help illuminate health effects resulting from intersections of residential processes, race/ethnicity, immigration, and other social determinants of health. For example, nativity and immigration history may crucially shape residential processes and exposures, but these have received limited attention in prior segregation-health literature.

    Full Text Available The purpose of the study was to investigate the potential impact of distance education on a small, rural, Canadian island community. Presently, the population of small, rural island communities on the west coast of Canada are facing numerous challenges to retain and to attract permanent residents and families and to provide support and direction for those residents who wish to pursue K-12 accreditation, post-secondary education, vocational/trades training and up-grading or life-long learning. A unique set of considerations confront many of these isolated communities if they wish to engage in distance education and training. This set ranges from internet access to excessive travel by secondary students to the lack of centralized facility. For this study, a group of 48 participants were interviewed to determine their perceptions of the potential for distance education to impact on the community's educational, both academic and vocational, life-long learning and economic needs. The results indicated that there were four general areas of purported benefit: academic advancement, an improved quality of life, support for young families and a stabilizing affect on the local economy. Suggestions for the implementation of a suitable distance education resource are noted.

  5. Advanced maintenance strategies for power plant operators--introducing inter-plant life cycle management

    2004-01-01

    One of the most important goals of competing power plant operators is to ensure safe operation of their plants, characterized by maximum availability throughout the entire life cycle and minimized specific generating costs. One parameter crucial to the total price of electricity--and one that can be actively influenced by the power plant operators--is maintenance. Up to 30% of all electricity generating costs accrue from maintenance. In the past years maintenance measures have been optimized particularly by the application and continuing development of testing and diagnostic techniques, by the increased level of system and component automation as well as more efficient organization structures. Despite the considerable success of these efforts, the potential for further cost reductions is still far from exhausted. But the risks connected to reliability, availability and safety need to be analyzed in greater detail in order to ensure the sustainability of the savings already achieved as well as those yet to be realized. The systematic application of condition-based maintenance and the implementation of structured life cycle management are essential requirements. An inter-plant approach is recommended to make a quick implementation of maintenance optimization potentials possible. Plant-specific improvement potentials can be established with the help of a best-practice comparison, and measures and priorities can be defined for realizing them. Creating an inter-plant database will allow experience and findings to be analyzed quickly and efficiently by experts and made available to all participants on a neutral platform. Despite--or maybe owing to--the increasingly competitive marketplace, a sustained reduction in the maintenance costs of power plant operators can only be achieved through a structured, inter-plant exchange of experience. The ZES offers the industry a suitable platform for cooperation with its 'Condition-Based Maintenance' research focus. The introduction

    2014-11-01

    Full Text Available To meet Energy Independence and Security Act (EISA cellulosic biofuel mandates, the United States will require an annual domestic supply of about 242 million Mg of biomass by 2022. To improve the feedstock logistics of lignocellulosic biofuels in order to access available biomass resources from areas with varying yields, commodity systems have been proposed and designed to deliver quality-controlled biomass feedstocks at preprocessing “depots”. Preprocessing depots densify and stabilize the biomass prior to long-distance transport and delivery to centralized biorefineries. The logistics of biomass commodity supply chains could introduce spatially variable environmental impacts into the biofuel life cycle due to needing to harvest, move, and preprocess biomass from multiple distances that have variable spatial density. This study examines the uncertainty in greenhouse gas (GHG emissions of corn stover logistics within a bio-ethanol supply chain in the state of Kansas, where sustainable biomass supply varies spatially. Two scenarios were evaluated each having a different number of depots of varying capacity and location within Kansas relative to a central commodity-receiving biorefinery to test GHG emissions uncertainty. The first scenario sited four preprocessing depots evenly across the state of Kansas but within the vicinity of counties having high biomass supply density. The second scenario located five depots based on the shortest depot-to-biorefinery rail distance and biomass availability. The logistics supply chain consists of corn stover harvest, collection and storage, feedstock transport from field to biomass preprocessing depot, preprocessing depot operations, and commodity transport from the biomass preprocessing depot to the biorefinery. Monte Carlo simulation was used to estimate the spatial uncertainty in the feedstock logistics gate-to-gate sequence. Within the logistics supply chain GHG emissions are most sensitive to the

    An intention in 2003 to undertake a multicentre trial in the United Kingdom of compressions before and after defibrillation could not be realized because of concerns at the time in relation to informed consent. Instead, the new protocol was introduced in one ambulance service, ahead of the 2005 Guidelines, with greater emphasis on compressions. The results were monitored by analysis of electronic ECG downloads. Deficiencies in the standard of basic life support were identified but were not unique to our service. The introduction of metronomes and the provision of feedback to crews led to major improvements in performance. Our experience has implications for the emergency pre-hospital care of cardiac arrest.

    The trend to delay motherhood to the age of 30 and beyond is established in most high-income countries but relatively little is known about potential effects on maternal emotional well-being. This study investigates satisfaction with life during pregnancy and the first three years of motherhood in women expecting their first baby at an advanced and very advanced age. The study was based on the National Norwegian Mother and Child Cohort Study (MoBa) conducted by the Norwegian Institute of Public Health. Data on 18 565 nulliparous women recruited in the second trimester 1999-2008 were used. Four questionnaires were completed: at around gestational weeks 17 and 30, and at six months and three years after the birth. Medical data were retrieved from the national Medical Birth Register. Advanced age was defined as 32-37 years, very advanced age as ≥38 years and the reference group as 25-31 years. The distribution of satisfaction with life from age 25 to ≥40 years was investigated, and the mean satisfaction with life at the four time points was estimated. Logistic regression analyses based on generalised estimation equations were used to investigate associations between advanced and very advanced age and satisfaction with life when controlling for socio-demographic factors. Satisfaction with life decreased from around age 28 to age 40 and beyond, when measured in gestational weeks 17 and 30, and at six months and three years after the birth. When comparing women of advanced and very advanced age with the reference group, satisfaction with life was slightly reduced in the two older age groups and most of all in women of very advanced age. Women of very advanced age had the lowest scores at all time points and this was most pronounced at three years after the birth. First-time mothers of advanced and very advanced age reported a slightly lower degree of satisfaction with life compared with the reference group of younger women, and the age-related effect was greatest

    Nurses\\' knowledge regarding advance directives may affect their administration and completion in end-of-life care. Confidence among nurses is a barrier to the provision of quality end-of-life care. This study investigated nurses\\' knowledge of advance directives and perceived confidence in end-of-life care, in Hong Kong, Ireland, Israel, Italy and the USA using a cross-sectional descriptive design (n = 1089). In all countries, older nurses and those who had more professional experience felt more confident managing patients\\' symptoms at end-of-life and more comfortable stopping preventive medications at end-of-life. Nurses in the USA reported that they have more knowledge and experience of advance directives compared with other countries. In addition, they reported the highest levels of confidence and comfort in dealing with end-of-life care. Although legislation for advance directives does not yet exist in Ireland, nurses reported high levels of confidence in end-of-life care.

    One of the major challenges involved in the use of ceramic materials is ensuring adequate strength and durability. This activity has developed methodology which can be used during the design phase to predict the structural behavior of ceramic components. The effort involved the characterization of injection molded and hot isostatic pressed (HIPed) PY-6 silicon nitride, the development of nondestructive evaluation (NDE) technology, and the development of analytical life prediction methodology. Four failure modes are addressed: fast fracture, slow crack growth, creep, and oxidation. The techniques deal with failures initiating at the surface as well as internal to the component. The life prediction methodology for fast fracture and slow crack growth have been verified using a variety of confirmatory tests. The verification tests were conducted at room and elevated temperatures up to a maximum of 1371 {degrees}C. The tests involved (1) flat circular disks subjected to bending stresses and (2) high speed rotating spin disks. Reasonable correlation was achieved for a variety of test conditions and failure mechanisms. The predictions associated with surface failures proved to be optimistic, requiring re-evaluation of the components` initial fast fracture strengths. Correlation was achieved for the spin disks which failed in fast fracture from internal flaws. Time dependent elevated temperature slow crack growth spin disk failures were also successfully predicted.

    Anaerobic fungi (phylum Neocallimastigomycota) inhabit the gastrointestinal tract of mammalian herbivores, where they play an important role in the degradation of plant material. The Neocallimastigomycota represent the earliest diverging lineage of the zoosporic fungi; however, understanding of the relationships of the different taxa (both genera and species) within this phylum is in need of revision. Issues exist with the current approaches used for their identification and classification, and recent evidence suggests the presence of several novel taxa (potential candidate genera) that remain to be characterised. The life cycle and role of anaerobic fungi has been well characterised in the rumen, but not elsewhere in the ruminant alimentary tract. Greater understanding of the 'resistant' phase(s) of their life cycle is needed, as is study of their role and significance in other herbivores. Biotechnological application of anaerobic fungi, and their highly active cellulolytic and hemi-cellulolytic enzymes, has been a rapidly increasing area of research and development in the last decade. The move towards understanding of anaerobic fungi using -omics based (genomic, transcriptomic and proteomic) approaches is starting to yield valuable insights into the unique cellular processes, evolutionary history, metabolic capabilities and adaptations that exist within the Neocallimastigomycota. © 2014 Federation of European Microbiological Societies.

    We determined the after-tax income required to finance basic needs for Canadian elders living with different circumstances in terms of age, gender, city of residence, household size, homeowner or renter status, means of transportation, and health status. Using 2001 as our base year, we priced the typical expenses for food, shelter, medical, transportation, miscellaneous basic living items and home-based long-term care for elders living in five Canadian cities. This is the first Canadian study of basic living expenses tailored to elders instead of adults in general, prepared on an absolute rather than a relative basis. We also accounted for an individual's unique life circumstances and established the varying effect that they have on the cost of basic expenses, particularly for home care. We found that the maximum Guaranteed Income Supplement and Old Age Security benefit did not meet the cost of basic needs for an elder living in poor circumstances.

    Full Text Available This qualitative paper explores the lived experiences of one group of workers dislocated because of globalized trade policies who completed a hybrid Advanced Manufacturing Training Program (AMTP by taking advantage of Trade Adjustment Assistance (TAA, a federally-funded program for retraining workers dislocated because of trade policies. The research questions focus on how satisfied these workers are with the services and programs provided by TAA. Focus groups and survey instrument results indicate these workers found TAA services and processes cumbersome and time- consuming and actually had the effect of discouraging their education, training, and self- employment. The consequences of their dislocation as it relates to TAA experiences are increased frustration and dissatisfaction with the TAA program. Serious consideration for TAA policy changes should be deemed of utmost importance.

    1997-01-01

    A wide ranging discussion about the factors that have influenced oil and natural gas prices, the differences of the Canadian market from international markets, the differences between eastern and western Canadian markets, and shareholders' perspectives on recent commodity price developments was presented. Developments in the OPEC countries were reviewed, noting that current OPEC production of 25 mmbbls is about 60 per cent higher than it was in 1985. It is expected that OPEC countries will continue to expand capacity to meet expected demand growth and the continuing need created by the UN embargo on Iraqi oil sales. Demand for natural gas is also likely to continue to rise especially in view of the deregulation of the electricity industry where natural gas may well become the favored fuel for incremental thermal generation capacity. Prices of both crude oil and natural gas are expected to hold owing to unusually low storage levels of both fuels. The inadequacy of infrastructure, particularly pipeline capacity as a key factor in the Canadian market was noted, along with the dynamic that will emerge in the next several years that may have potential consequences for Canadian production - namely the reversal of the Sarnia to Montreal pipeline. With regard to shareholders' expectations the main issues are (1) whether international markets reach back to the wellhead, hence the producer's positioning with respect to transportation capacity and contract portfolios, and (2) whether the proceeds from increased prices are invested in projects that are yielding more than the cost of capital. 28 figs

    Canadian exports of gas to the United States are a critical component of EMF-9 (North American Gas Supplies). However, it has been noted that there are differences between US expectations for imports and Canadian forecasts of export supply capacity. Recent studies by the National Petroleum Council (NPC) and the US Department of Energy (DOE) indicate that 1.8 to 2.4 Tcf of imports may be required in the mid to late 1990's; A recent study by Canada's National Energy Board (NEB) indicates that the conventional resource base may not be able to provide continued gas exports to the US after the mid 1990's and that frontier sources would need to be developed to meet US expectations. The discrepancies between US expectations and Canadian estimates of capacity are of great concern to US policymakers because they call into question the availability of secure supplies of natural gas and suggest that the cost of imports (if available) will be high. By implication, if shortages are to be averted, massive investment may be required to bring these higher cost sources to market. Since the long-term supply picture will be determined by the underlying resource base, EMF-9 participants have been asked to provide estimates of critical components of the Canadian resource base. This paper provides a summary of ICF-Lewin's recent investigation of both the Conventional and Tight Gas resource in Canada's Western Sedimentary Basin, which includes both quantitative estimates and a brief sketch of the analysis methodology

    This study covers the following Canadian petroleum industry categories: (1) a brief history; (2) the demand for Alberta crude; (3) U.S. oil policies; (4) overseas exploration; (5) the national oil policy; (6) the Montreal pipeline and its targets; (7) a continental oil policy; and (8) the impact of Arctic reserves. It is noted that large potential benefits will improve from the Manhattan navigating the Northwest Passage. Without prejudging the analysis now applied to the information gathered on this voyage, the Manhattan has greatly contributed to the solution of the problem of access to the Arctic islands. The picture for natural gas is less fraught with uncertainties. Unlike oil, where domestic and international considerations may weigh in U.S. policy decision, Canadian natural gas is likely to be allowed to enjoy its full economic potential in bridging the foreseeable U.S. supply gap and, inasmuch as this potential is ultimately tied with that for crude oil markets, the anticipated U.S. needs for Canadian natural gas may be expected to enhance U.S. interest in the overall well-being of the Canadian petroleum industry.

    The Canadian hydrogen safety program (CHSP) is a project initiative of the Codes and Standards Working Group of the Canadian transportation fuel cell alliance (CTFCA) that represents industry, academia, government, and regulators. The Program rationale, structure and contents contribute to acceptance of the products, services and systems of the Canadian Hydrogen Industry into the Canadian hydrogen stakeholder community. It facilitates trade through fair insurance policies and rates, effective and efficient regulatory approval procedures and accommodation of the interests of the general public. The Program integrates a consistent quantitative risk assessment methodology with experimental (destructive and non-destructive) failure rates and consequence-of-release data for key hydrogen components and systems into risk assessment of commercial application scenarios. Its current and past six projects include Intelligent Virtual Hydrogen Filling Station (IVHFS), Hydrogen clearance distances, comparative quantitative risk comparison of hydrogen and compressed natural gas (CNG) refuelling options; computational fluid dynamics (CFD) modeling validation, calibration and enhancement; enhancement of frequency and probability analysis, and Consequence analysis of key component failures of hydrogen systems; and fuel cell oxidant outlet hydrogen sensor project. The Program projects are tightly linked with the content of the International Energy Agency (IEA) Task 19 Hydrogen Safety. (author)

    Meaning in life (MiL) is a construct that varies across individuals, situations, cultures, and countries, and protects against emotional distress at the end of life. To examine MiL in inpatients with advanced cancer from Barcelona, Spain, and to compare the findings with those obtained in German and Swiss samples. This was a cross-sectional study in which the Schedule for Meaning in Life Evaluation (SMiLE) was administered. The SMiLE asks respondents to list individual areas that give meaning in their lives and then to rate their current level of importance and satisfaction with the listed areas. A total of 101 inpatients completed the SMiLE. The Index of Satisfaction was 76.8 ± 21.1, the Index of Weighting was 88.0 ± 13.0, and the Index of Weighted Satisfaction was 76.9 ± 20.7. Family, partnership, well-being, and friends were the four areas listed by the largest proportion of Spanish patients. Compared with the German sample, Spanish patients were more likely to list well-being (P German and Swiss counterparts, the Spanish patients listed more areas involving interpersonal relationships. Interpersonal relationships, at both the family and wider social level, are reported to be the areas that give the greatest MiL to these patients. These aspects, therefore, should be considered when drawing up care plans designed to help patients achieve the maximum possible comfort and quality of life.

    Advance care planning (ACP) involves several behaviors that individuals undertake to prepare for future medical care should they lose decision-making capacity. The goal of this study was to assess whether playing a conversation game could motivate participants to engage in ACP. Sixty-eight English-speaking, adult volunteers (n = 17 games) from communities around Hershey, Pennsylvania, and Lexington, Kentucky, played a conversation card game about end-of-life issues. Readiness to engage in 4 ACP behaviors was measured by a validated questionnaire (based on the transtheoretical model) immediately before and 3 months postgame and a semistructured phone interview. These behaviors were (1) completing a living will; (2) completing a health-care proxy; (3) discussing end-of-life wishes with loved ones; and (4) discussing quality versus quantity of life with loved ones. Participants' (n = 68) mean age was 51.3 years (standard deviation = 0.7, range: 22-88); 94% of the participants were caucasian and 67% were female. Seventy-eight percent of the participants engaged in ACP behaviors within 3 months of playing the game (eg, updating documents, discussing end-of-life issues). Furthermore, 73% of the participants progressed in stage of change (ie, readiness) to perform at least 1 of the 4 behaviors. Scores on measures of decisional balance and processes of change increased significantly by 3 months postintervention. This pilot study found that individuals who played a conversation game had high rates of performing ACP behaviors within 3 months. These findings suggest that using a game format may be a useful way to motivate people to perform important ACP behaviors.

    Regenerative environmental control and life support system (ECLSS) technologies are found by the present evaluation to have reached a degree of maturity that recommends their application to long duration manned missions. The missions for which regenerative ECLSSs are attractive in virtue of the need to avoid expendables and resupply requirements have been identified as that of the long duration LEO Space Station, long duration stays at GEO, a permanently manned lunar base (or colony), manned platforms located at the earth-moon libration points L4 or L5, a Mars mission, deep space exploration, and asteroid exploration. A comparison is made between nonregenerative and regenerative ECLSSs in the cases of 10 essential functions.

    Steam generators are a critical component of a nuclear power reactor, and can contribute significantly to station unavailability, as has been amply demonstrated in Pressurized Water Reactors (PWRs). CANDU steam generators are not immune to steam generator degradation, and the variety of CANDU steam generator designs and tube materials has led to some unexpected challenges. However, aggressive remedial actions, and careful proactive maintenance activities, have led to a decrease in steam generator-related station unavailability of Canadian CANDUs. AECL and the CANDU utilities have defined programs that will enable existing or new steam generators to operate effectively for 40 years. Research and development work covers corrosion and mechanical degradation of tube bundles and internals, chemistry, thermal hydraulics, fouling, inspection and cleaning, as well as provision for specially tool development for specific problem solving. A major driving force is development of CANDU-specific fitness-for-service guidelines, including appropriate inspection and monitoring technology to measure steam generator condition. Longer-range work focuses on development of intelligent on-line monitoring for the feedwater system and steam generator. New designs have reduced risk of corrosion and fouling, are more easily inspected and cleaned, and are less susceptible to mechanical damage. The Canadian CANDU utilities have developed programs for remedial actions to combat degradation of performance (Gentilly-2, Point Lepreau, Bruce A/B, Pickering A/B), and have developed strategic plans to ensure that good future operation is ensured. This report shows how recent advances in cleaning technology are integrated into a life management strategy, discusses downcomer flow measurement as a means of monitoring steam generator condition, and describes recent advances in hideout return as a life management tool. The research and development program, as well as operating experience, has identified

    Undue influence from family members of patients with advanced cancer remains a serious ethical problem in end-of-life decision making. Despite the wealth of articles discussing the problem of undue influence, little has been written by way of practical guidance to help clinicians identify and effectively manage situations of undue influence. This article briefly lays out how to identify and manage situations of undue influence sensitively and effectively. We explain how undue influence may present itself in the clinic and distinguish it from ethically permissible expressions of relational autonomy. In addition, we lay out a process by which any clinician suspecting undue influence may gather additional information and, if necessary, conduct a family meeting to address the undue influence. It is our hope that by providing clinicians at all levels of patient care with such guidance, they will feel empowered to respond to cases of undue influence when they arise.

    An advanced solid propellant was characterized. The propellant was based on a glycidyl azide polymer (GAP) energetic binder with an ammonium nitrate (AN) oxidizer, and contained a significant percentage of triaminoguanidine nitrate (TAGN). Raw ingredient accelerating rate calorimetry (ARC) was performed to determine self-heating rates. Thermal stability and heat flow calorimetry tests were also conducted. Ballistic analyses were conducted to determine the propellant's burn rate. The propellant was designed to produce non-toxic and non-acidic exhaust products. Results of the tests indicated that the propellant is safe for prolonged storage. The study demonstrated that propellant samples can be heated to temperatures up to 175 degrees C for several hours without combustion response. A mass loss of 62 per cent was observed at temperatures between 160 and 230 degrees C. The samples ignited almost immediately after being placed in a pre-heated block at temperatures higher than 175 degrees C. The propellant's burn rate was approximately twice that of standard AN propellants. The propellant will be further evaluated as a candidate for the propulsion of tactical rockets and missiles. 17 refs., 4 tabs., 6 figs.

    Minimally processed fresh produce is one of the fastest growing segments of the food industry due to consumer demand for fresh, healthy, and convenient foods. However, mechanical operations of cutting and peeling induce the liberation of cellular contents at the site of wounding that can promote the growth of pathogenic and spoilage microorganisms. In addition, rates of tissue senescence can be enhanced resulting in reduced storage life of fresh-cut fruits and vegetables. Chlorine has been widely adopted in the disinfection and washing procedures of fresh-cut produce due to its low cost and efficacy against a broad spectrum of microorganisms. Continuous replenishment of chlorine in high organic wash water can promote the formation of carcinogenic compounds such as trihalomethanes, which threaten human and environmental health. Alternative green and innovative chemical and physical postharvest treatments such as ozone, electrolyzed water, hydrogen peroxide, ultraviolet radiation, high pressure processing, and ultrasound can achieve similar reduction of microorganisms as chlorine without the production of harmful compounds or compromising the quality of fresh-cut produce.

    he past decade has seen an explosion of new technologies for assessment of biogenicity and syngeneity of carbonaceous material within sedimentary rocks. Advances have been made in techniques for analysis of in situ organic matter as well as for extracted bulk samples of soluble and insoluble (kerogen) organic fractions. The in situ techniques allow analysis of micrometer-to-sub-micrometer-scale organic residues within their host rocks and include Raman and fluorescence spectroscopy/imagery, confocal laser scanning microscopy, and forms of secondary ion/laser-based mass spectrometry, analytical transmission electron microscopy, and X-ray absorption microscopy/spectroscopy. Analyses can be made for chemical, molecular, and isotopic composition coupled with assessment of spatial relationships to surrounding minerals, veins, and fractures. The bulk analyses include improved methods for minimizing contamination and recognizing syngenetic constituents of soluble organic fractions as well as enhanced spectroscopic and pyrolytic techniques for unlocking syngenetic molecular signatures in kerogen. Together, these technologies provide vital tools for the study of some of the oldest and problematic carbonaceous residues and for advancing our understanding of the earliest stages of biological evolution on Earth and the search for evidence of life beyond Earth. We discuss each of these new technologies, emphasizing their advantages and disadvantages, applications, and likely future directions.

  13. Financial outlook for the Canadian gas industry

    Friedenberg, B.

    1994-01-01

    The financial outlook for the Canadian natural gas industry is discussed in terms of the price of Canadian gas and its production and transportation costs. Demand growth for natural gas is fairly steady, reflecting economic growth and technological advances. Supply growth is more volatile, overshooting demand growth in an up market and undershooting in a down market. In the past year and a half, gas prices have improved as the supply deliverability surplus has eroded. It is predicted that supply will again exceed demand and prices will decline, the length of this price cycle being a few years. Production costs for western Canadian gas had been declining during the mid-1980s to 1991, and current replacement costs average ca $1.87/GJ. It is doubtful that fieldgate costs will increase to overtake fieldgate market prices and the Canadian gas industry will remain in a healthy state. The availability and cost of gas transport, however, is critically important. The major costs of pipeline transport are fixed demand charges and the value of transport services out of western Canada is determined by the demand and the supply (the location and size of the pipeline infrastructure, which is essentially fixed over short to medium time frames). This value can vary significantly as the demand for pipeline space varies both daily and seasonally. Excess pipeline capacity is generally good for the Canadian producing industry since it lowers transport costs, but excess capacity also plays a role in linking producing-basin and market area prices to one another. This is illustrated for the case of Alberta and Texas gas prices, which show higher correlation with falling load factors on ex-Alberta pipeline capacity. 5 figs

    2018-01-01

    As a result of the rapidly growing global population and limited agricultural area, sufficient supply of cereals for food and animal feed has become increasingly challenging. Consequently, it is essential to reduce pre- and post-harvest crop losses. Extensive research, featuring several physical treatments, has been conducted to improve cereal post-harvest preservation, leading to increased food safety and sustainability. Various pests can lead to post-harvest losses and grain quality deterioration. Microbial spoilage due to filamentous fungi and bacteria is one of the main reasons for post-harvest crop losses and mycotoxins can induce additional consumer health hazards. In particular, physical treatments have gained popularity making chemical additives unnecessary. Therefore, this review focuses on recent advances in physical treatments with potential applications for microbial post-harvest decontamination of cereals. The treatments discussed in this article were evaluated for their ability to inhibit spoilage microorganisms and degrade mycotoxins without compromising the grain quality. All treatments evaluated in this review have the potential to inhibit grain spoilage microorganisms. However, each method has some drawbacks, making industrial application difficult. Even under optimal processing conditions, it is unlikely that cereals can be decontaminated of all naturally occurring spoilage organisms with a single treatment. Therefore, future research should aim for the development of a combination of treatments to harness their synergistic properties and avoid grain quality deterioration. For the degradation of mycotoxins the same conclusion can be drawn. In addition, future research must investigate the fate of degraded toxins, to assess the toxicity of their respective degradation products. PMID:29565832

    This study examined social workers' roles in caring for low-income elders with advanced chronic disease in an innovative, community-based managed care program, from the perspective of elders, family, team members, and social workers. The results are drawn from a larger longitudinal, multimethod case study. Sources of data include survey reports of needs addressed by social workers for 120 deceased elders, five focus groups with interdisciplinary team members, and in-depth interviews with 14 elders and 10 of their family caregivers. A thematic conceptual matrix was developed to detail 32 distinctive social work roles that address divergent needs of elders, family, and team members. Distinctive perceptions of social workers' roles were identified for the different stakeholder groups (i.e., elders, family caregivers, team members, and social workers). Findings from this study may inform supervisors and educators regarding training needs of those preparing to enter the rapidly growing workforce of gerontological social workers who may be called upon to care for elders at the end of life. Training is particularly warranted to help social workers gain the skills needed to more successfully treat symptom management, depression, anxiety, agitation, grief, funeral planning, and spiritual needs that are common to the end of life.

    Background Despite increasing awareness about the importance of discussing end-of-life (EOL) care options with terminally ill patients and families, many physicians remain uncomfortable with these discussions. Objective The objective of the study was to examine perceptions of and comfort with EOL care discussions among a group of internal medicine residents and the extent to which comfort with these discussions has improved over time. Methods In 2013, internal medicine residents at a large academic medical center were asked to participate in an on-line survey that assessed their attitudes and experiences with discussing EOL care with terminally-ill patients. These results were compared to data from a similar survey residents in the same program completed in 2006. Results Eighty-three (50%) residents completed the 2013 survey. About half (52%) felt strongly that they were able to have open, honest discussions with patients and families, while 71% felt conflicted about whether CPR was in the patient’s best interest. About half (53%) felt strongly that it was okay for them to tell a patient/family member whether or not CPR was a good idea for them. Compared to 2006 respondents, the 2013 cohort felt they had more lectures about EOL communication, and had watched an attending have an EOL discussion more often. Conclusions Modest improvements were made over time in trainees’ exposure to EOL discussions; however, many residents remain uncomfortable and conflicted with having EOL care discussions with their patients. More effective training approaches in EOL communication are needed to train the next generation of internists. PMID:24418692

    The application of DNA-based markers toward the task of discriminating among alternate salmon runs has evolved in accordance with ongoing genomic developments and increasingly has enabled resolution of which genetic markers associate with important life-history differences. Accurate and efficient identification of the most likely origin for salmon encountered during ocean fisheries, or at salvage from fresh water diversion and monitoring facilities, has far-reaching consequences for improving measures for management, restoration and conservation. Near-real-time provision of high-resolution identity information enables prompt response to changes in encounter rates. We thus continue to develop new tools to provide the greatest statistical power for run identification. As a proof of concept for genetic identification improvements, we conducted simulation and blind tests for 623 known-origin Chinook salmon (Oncorhynchus tshawytscha) to compare and contrast the accuracy of different population sampling baselines and microsatellite loci panels. This test included 35 microsatellite loci (1266 alleles), some known to be associated with specific coding regions of functional significance, such as the circadian rhythm cryptochrome genes, and others not known to be associated with any functional importance. The identification of fall run with unprecedented accuracy was demonstrated. Overall, the top performing panel and baseline (HMSC21) were predicted to have a success rate of 98%, but the blind-test success rate was 84%. Findings for bias or non-bias are discussed to target primary areas for further research and resolution. © 2014 The Authors.

    Maintenance of crew health is of paramount importance for long duration space missions. Weight loss, bone and calcium loss, increased exposure to radiation and oxidative stress are critical concerns that need to be alleviated. Rational nutrition is a resource for mitigating the influence of unfavorable conditions. The insufficiency of vegetarian diet has been examined by the Japanese, Chinese and U.S. developers of bioregenerative life support systems (BLSS). Hence, inclusion of animals such as silkworm in BLSS looks justified. The giant snail is currently under studying as a source of animal food and a species of reducing waste in BLSS. An experimental system to conduct cultivation of giant snail was developed. It was established that there are some reasons to use the giant snails in BLSS. It could be a source of delicious meat. A. fulica is capable of consuming a wide range of feedstuffs including plant residues. Cultivation of snail in the limited volume does not demand the big expenditures of labor. The production of crude edible biomass and protein of A. fulica was 60±15 g and 7±1.8 g respectively per 1 kg of consumed forage (fresh salad leaves, root and leafy tops of carrot). To satisfy daily animal protein needs (30-35 g) a crewman has to consume 260-300 g of snail meat. To produce such amount of snail protein it takes to use 4.3-5.0 kg of plant forage daily. The nutritional composition of A. fulica whole bodies (without shell) and a meal prepared in various ways was quantitatively determined. Protein, carbohydrate, fat acid and ash content percentages were different among samples prepared in various ways. The protein content was highest (68 %) in the dry sample washed with CH3 COOH solution. Taking into consideration the experimental results a conceptual configuration of BLSS with inclusion of giant snail was developed and mass flow rates between compartments were calculated. Keywords: animal food; protein; giant snail; BLSS; conceptual configuration.

  1. Advanced anaerobic bioconversion of lignocellulosic waste for the melissa life support system

    Lissens, G.; Verstraete, W.; Albrecht, T.; Brunner, G.; Creuly, C.; Dussap, G.; Kube, J.; Maerkl, H.; Lasseur, C.

    The feasibility of nearly-complete conversion of lignocellulosic waste (70% food crops, 20% faecal matter and 10% green algae) into biogas was investigated in the context of the MELiSSA loop (Micro-Ecological Life Support System Alternative). The treatment comprised a series of processes, i.e. a mesophilic laboratory scale CSTR (continuously stirred tank reactor), an upflow biofilm reactor, a fiber liquefaction reactor employing the rumen bacterium Fibrobacter succinogenes and a hydrothermolysis system in near-critical water. By the one-stage CSTR, a biogas yield of 75% with a specific biogas production of 0.37 l biogas g-1 VSS (volatile suspended solids) added at a RT (hydraulic retention time) of 20-25 d was obtained. Biogas yields could not be increased considerably at higher RT, indicating the depletion of readily available substrate after 25 d. The solids present in the CSTR-effluent were subsequently treated in two ways. Hydrothermal treatment (T ˜ 310-350C, p ˜ 240 bar) resulted in effective carbon liquefaction (50-60% without and 83% with carbon dioxide saturation) and complete sanitation of the residue. Application of the cellulolytic Fibrobacter succinogenes converted remaining cellulose contained in the CSTR-effluent into acetate and propionate mainly. Subsequent anaerobic digestion of the hydrothermolysis and the Fibrobacter hydrolysates allowed conversion of 48-60% and 30%, respectively. Thus, the total process yielded biogas corresponding with conversions up to 90% of the original organic matter. It appears that particularly mesophilic digestion in conjunction with hydrothermolysis offers interesting features for (nearly) the MELiSSA system. The described additional technologies show that complete and hygienic carbon and energy recovery from human waste within MELiSSA is technically feasible, provided that the extra energy needed for the thermal treatment is guaranteed.

    Applying prospect theory to end-of-life decision making, we hypothesize that community-dwelling older adults (CDOAs) will be relatively less inclined towards extending length over improving quality of life compared with patients. We also hypothesize that differences in relative inclination for length over quality of life between the 2 groups will decrease with advancing age. We tested these hypotheses by administering the quality-quantity questionnaire to 1067 CDOAs and 320 stage IV cancer patients and applying a linear regression model to assess whether relative inclination for length over quality of life, as estimated by the questionnaire, differed between CDOAs and patients after controlling for differences in sociodemographic characteristics. We also assessed the effect of interaction between age and participant status (CDOA compared to patient) on relative inclination for length over quality of life. Consistent with prospect theory, a lower proportion of CDOAs (26%) than patients (42%) were relatively more inclined towards length over quality of life. Results were significant even after adjusting for differences in sociodemographics (P patients increased (P = .01). Findings indicate that attitudes towards length and quality of life differ by life stage. This has implications for end-of-life care decisions made by CDOAs, such as purchasing health or disability insurance and signing advance directives or care plans.

    This pilot study aimed to investigate quality of life, psychological burden, unmet needs, and care satisfaction in family caregivers of advanced cancer patients (FCs) during specialized inpatient palliative care (SIPC) and to test feasibility and acceptance of the questionnaire survey. During a period of 12 weeks, FCs were recruited consecutively within 72 h after the patient's admission. They completed validated scales on several outcomes: quality of life (SF-8), distress (DT), anxiety (GAD-7), depression (PHQ-9), supportive needs (FIN), palliative care outcome (POS), and satisfaction with care (FAMCARE-2). We used non-parametric tests, t-tests and correlation analyses to address our research questions. FCs showed high study commitment: 74 FCs were asked to participate whereof 54 (73%) agreed and 51 (69%) returned the questionnaire. Except for "bodily pain", FCs' quality of life (SF-8) was impaired in all subscales. Most FCs (96%) reported clinically significant own distress (DT), with sadness, sorrows and exhaustion being the most distressing problems (80-83%). Moderate to severe anxiety (GAD-7) and depression (PHQ-9) were prevalent in 43% and 41% of FCs, respectively. FCs scored a mean number of 16.3 of 20 needs (FIN) as very or extremely important (SD 3.3), 20% of needs were unmet in >50% of FCs. The mean POS score assessed by FCs was 16.6 (SD 5.0) and satisfaction (FAMCARE-2) was high (73.4; SD 8.3). This pilot study demonstrated feasibility of the questionnaire survey and showed relevant psychosocial burden and unmet needs in FCs during SIPC. However, FCs' satisfaction with SIPC seemed to be high. A current multicenter study evaluates these findings longitudinally in a large cohort of FCs.

    The development of chemistry during the twentieth century has changed our lives. In fact, chemistry and chemicals surrounds US in our daily activities, due to the huge supply of products aimed at improving our quality of life. Chemistry has resulted in the medical revolution of the past century, in which drugs as antibiotics have been used to cure diseases that affected mankind for centuries. These advances have led to the rise in the average life expectancy from 47 in 1900, to 75 years in the 1990s (Breslow 1997). On the other hand, the world's food supply has seen an explosive expansion because of the development of pesticides as well as fertilisers that protect crops and improve their productivity. Other common chemicals are those related to hygiene, such as soaps, detergents, disinfectants, toothpaste, etc. Therefore, there is practically no facet in material life-transportation communication, clothing, shelter, office- in which chemistry does not play an important role, either to supply consumer products or to improve services addressed to society in general (Domenech 2005). In spite of all these clear benefits, the chemical industry is often viewed by the general public as causing more harm than good (Lancaster 2002). A major reason for this is that the industry is perceived as being polluting and causing significant environmental damage. Indeed, the manufacture, use and disposal of chemicals consume large amounts of resources, and originates emissions of pollutants to all environmental compartments, not to mention the numerous accidents and disasters in which the chemical industry has been involved in the recent past.

    Little is known about how physician and parent perspectives compare regarding the prognosis and end-of-life (EOL) experience of children with advanced heart disease (AHD). The study's objective was to describe and compare parent and physician perceptions regarding prognosis and EOL experience in children with AHD. This was a cross-sectional survey study of cardiologists and bereaved parents. Study subjects were parents and cardiologists of children with primary cardiac diagnoses who died in a tertiary care pediatric hospital between January 2007 and December 2009. Inclusion required both physician and parent to have completed surveys respective to the same patient. A total of 31 parent/physician pairs formed the analytic sample. Perceptions were measured of cardiologists and bereaved parents regarding the EOL experience of children with AHD. Nearly half of parents and physicians felt that patients suffered 'a great deal,' 'a lot,' or 'somewhat' at EOL, but there was no agreement between them. At diagnosis, parents more often expected complete repair and normal lifespan while the majority of physicians expected shortened lifespan without normal quality of life. Parents who expected complete repair with normal life were more likely to report 'a lot' of suffering at EOL (p=0.002). In 43% of cases, physicians reported that the parents were prepared for the way in which their child died, while the parents reported feeling unprepared. Both parents and physicians perceive suffering at EOL in patients who die of AHD. Moreover, parent expectations at diagnosis may influence perceptions of suffering at EOL. Physicians overestimate the degree of parent preparedness for their child's death.

    By maintaining sufficient cerebral blood flow and oxygenation, the goal of cardiopulmonary resuscitation (CPR) is to preserve the pre-arrest neurological state. To date, cerebral monitoring abilities during CPR have been limited. Therefore, we investigated the time-course of cerebral oxygen saturation values (rSO₂) during advanced life support in out-of-hospital cardiac arrest. Our primary aim was to compare rSO₂ values during advanced life support from patients with return of spontaneous circulation (ROSC) to patients who did not achieve ROSC. We performed an observational study to measure rSO₂ using Equanox (Nonin, Plymouth, MI) from the start of advanced life support in the pre-hospital setting. rSO₂ of 49 consecutive out-of-hospital cardiac arrest patients were analyzed. The total increase from initial rSO₂ value until two minutes before ROSC or end of advanced life support efforts was significantly larger in the group with ROSC 16% (9 to 36) compared to the patients without ROSC 10% (4 to 15) (P = 0.02). Mean rSO₂ from the start of measurement until two minutes before ROSC or until termination of advanced life support was higher in patients with ROSC than in those without, namely 39% ± 7 and 31% ± 4 (P = 0.05) respectively. During pre-hospital advanced life support, higher increases in rSO₂ are observed in patients attaining ROSC, even before ROSC was clinically determined. Our findings suggest that rSO₂ could be used in the future to guide patient tailored treatment during cardiac arrest and could therefore be a surrogate marker of the systemic oxygenation state of the patient.

    It is unknown whether cancer patients with different life expectancies have different attitudes and emotions toward death and an afterlife. Also, it is unclear whether these attitudes and emotions toward death and afterlife influence patients' distress. To assess the relationship of attitudes and emotions towards death and an afterlife with quality of life, depression and hopelessness in cancer patients without evidence of disease and advanced cancer patients facing death. Ninety-one cancer patients without evidence of disease and 57 advanced cancer patients completed the Dutch Attitudes Toward Death and Afterlife Scale. Emotions toward death were measured using the Self-Confrontation Method. Quality of life was measured with the Satisfaction with Life Scale and the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire. Depression and hopelessness were measured with the Beck Depression Inventory for Primary Care and the Beck Hopelessness Scale. Average scores on attitudes and emotions toward death and an afterlife were not significantly different between the two groups. However, in the no evidence of disease group, a negative association between negative emotions and social functioning was observed, which was not present in the advanced cancer group. In the advanced cancer group, associations were observed that were not present in the no evidence of disease group: positive associations between an explicitly religious attitude and global health status and between reincarnation belief and role and cognitive functioning, and a negative association between other-directed emotions and social functioning. Patients without evidence of disease and advanced cancer patients do not differ in attitudes or emotions toward death, but the relationship between these attitudes and emotions and aspects of quality of life varies. When there is no evidence of disease, negative emotions play the most important role, whereas in the advanced

    On October 18, 2010, the NASA Human Health and Performance center (NHHPC) was opened to enable collaboration among government, academic and industry members. Membership rapidly grew to 90 members (http://nhhpc.nasa.gov ) and members began identifying collaborative projects as detailed in this article. In addition, a first workshop in open collaboration and innovation was conducted on January 19, 2011 by the NHHPC resulting in additional challenges and projects for further development. This first workshop was a result of the SLSD successes in running open innovation challenges over the past two years. In 2008, the NASA Johnson Space Center, Space Life Sciences Directorate (SLSD) began pilot projects in open innovation (crowd sourcing) to determine if these new internet-based platforms could indeed find solutions to difficult technical problems. From 2008 to 2010, the SLSD issued 34 challenges, 14 externally and 20 internally. The 14 external challenges were conducted through three different vendors: InnoCentive, Yet2.com and TopCoder. The 20 internal challenges were conducted using the InnoCentive platform, customized to NASA use, and promoted as NASA@Work. The results from the 34 challenges involved not only technical solutions that were reported previously at the 61st IAC, but also the formation of new collaborative relationships. For example, the TopCoder pilot was expanded by the NASA Space Operations Mission Directorate to the NASA Tournament Lab in collaboration with Harvard Business School and TopCoder. Building on these initial successes, the NHHPC workshop in January of 2011, and ongoing NHHPC member discussions, several important collaborations have been developed: (1) Space Act Agreement between NASA and GE for collaborative projects (2) NASA and academia for a Visual Impairment / Intracranial Hypertension summit (February 2011) (3) NASA and the DoD through the Defense Venture Catalyst Initiative (DeVenCI) for a technical needs workshop (June 2011) (4

    Beset by unprecedented fiscal pressures, Canadian medicare has reached a crossroads. The authors review the impact of recent cuts in federal transfer payments on provincial health care programs and offer seven suggestions to policymakers trying to accommodate these reductions. (1) Go slowly: public health care spending is no longer rising and few provinces have the necessary systems in place to manage major reductions. (2) Target reductions, rewarding quality and efficiency instead of making across-the-board cuts. (3) Replace blame with praise:give health care professionals and institutions credit for their contributions. (4) Learn from the successful programs and policies already in place across the country. (5) Foster horizontal and vertical integration of services. (6) Promote physician leadership by rewarding efforts to promote the efficient use of resources. (7) Monitor the effects of cutbacks: physician groups should cooperate with government in maintaining a national "report card" on services, costs and the health status of Canadians.

    The National Research Council of Canada is establishing a coordinated national program of fusion research and development that is planned to grow to a total annual operating level of about $20 million in 1985. The long-term objective of the program is to put Canadian industry in a position to manufacture sub-systems and components of fusion power reactors. In the near term the program is designed to establish a minimum base of scientific and technical expertise sufficient to make recognized contributions and thereby gain access to the international effort. The Canadian program must be narrowly focussed on a few specializations where Canada has special indigenous skills or technologies. The programs being funded are the Tokamak de Varennes, the Fusion Fuels Technology Project centered on tritium management, and high-power gas laser technology and associated diagnostic instrumentation

  17. Tuberculosis in Aboriginal Canadians

    Directory of Open Access Journals (Sweden)

    Vernon H Hoeppner

    2000-01-01

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

    This PowerPoint presentation discussed initiatives and strategies adopted by the Canadian Wind Energy Association (CanWEA) to support the development of Canada's small wind market. The general public has shown a significant interest in small wind projects of 300 kW. Studies have demonstrated that familiarity and comfort with small wind projects can help to ensure the successful implementation of larger wind projects. Small wind markets include residential, farming and commercial, and remote community applications. The results of CanWEA market survey show that the small wind market grew by 78 percent in 2008 over 2007, and again in 2009 by 32 percent over 2008. The average turbine size is 1 kW. A total of 11,000 turbines were purchased in 2007 and 2008. Global small wind market growth increased by 110 percent in 2008, and the average turbine size was 2.4 kW. Eighty-seven percent of the turbines made by Canadian mid-size wind turbine manufacturers are exported, and there is now a significant risk that Canada will lose its competitive advantage in small wind manufacturing as financial incentives have not been implemented. American and Canadian-based small wind manufacturers were listed, and small wind policies were reviewed. The presentation concluded with a set of recommendations for future incentives, educational programs and legislation. tabs., figs.

  19. Canadian ethane market overview

    Stauft, T. [TransCanada Midstream, Calgary, AB (Canada)

    1999-07-01

    A review of the Canadian petrochemical industry, the supply and demand for ethane, and the longer-term outlook for ethane are presented. Recent projections of natural gas production by the National Energy Board are examined, along with the impact on ethane supply and demand by Alliance. It is suggested that reduced gas will flow past Cochrane and Empress, Alberta ethane and gas prices will increase relative to US Gulf Coast prices, and since expansion is based on ethane demand, the combined influence of these factors will be to delay the construction of new extraction capacity. Present capacity is considered sufficient to produce ethane for the current round of petrochemical plant expansions. Excess supplies will exist for the next few years, and Alberta ethane prices are likely to strengthen due to the tight supply/demand balance. The combination of the impact of the Alliance Pipeline project and the ultimate potential of the Western Canadian Sedimentary Basin are the major uncertainties. On the plus side, both the US and Canadian regulatory agencies appear to be moving away from regulating ethane, and towards allowing a competitive market to develop.

    A review of the Canadian petrochemical industry, the supply and demand for ethane, and the longer-term outlook for ethane are presented. Recent projections of natural gas production by the National Energy Board are examined, along with the impact on ethane supply and demand by Alliance. It is suggested that reduced gas will flow past Cochrane and Empress, Alberta ethane and gas prices will increase relative to US Gulf Coast prices, and since expansion is based on ethane demand, the combined influence of these factors will be to delay the construction of new extraction capacity. Present capacity is considered sufficient to produce ethane for the current round of petrochemical plant expansions. Excess supplies will exist for the next few years, and Alberta ethane prices are likely to strengthen due to the tight supply/demand balance. The combination of the impact of the Alliance Pipeline project and the ultimate potential of the Western Canadian Sedimentary Basin are the major uncertainties.

    Abstract: The lexicographical record of English in Canada began with wordlists of the late eighteenth, nineteenth, and early twentieth centuries. From the beginning of the twentieth century onwards, the general vocabulary of English in Canada has been represented in bilingual and monolingual dictionaries, often adapted from American or British dictionaries. In the 1950s, several important projects were initiated, resulting in the publication of general dictionaries of English in Canada, and of dictionaries of Canadianisms and of the vocabulary of particular regions of Can-ada. This article gives an overview of these dictionaries and of their reception, contextualizing them in the larger picture of the lexicography of Canada's other official language, French, and of a number of its non-official languages. It concludes by looking at the future of English-language lexicography in Canada, and by observing that although it has, at its best, reached a high degree of sophistication, there are still major opportunities waiting to be taken.

    Full Text Available Advance Care Plans (ACPs enable patients to discuss and negotiate their preferences for the future including treatment options at the end of life. Their implementation poses significant challenges.To investigate barriers and facilitators to the implementation of ACPs, focusing on their workability and integration in clinical practice.An explanatory systematic review of qualitative implementation studies.Empirical studies that reported interventions designed to support ACP in healthcare. Web of Knowledge, Ovid MEDLINE, CINAHL, PsycINFO, British Nursing Index and PubMed databases were searched.Direct content analysis, using Normalization Process Theory, to identify and characterise relevant components of implementation processes.13 papers identified from 166 abstracts were included in the review. Key factors facilitating implementation were: specially prepared staff utilizing a structured approach to interactions around ACPs. Barriers to implementation were competing demands of other work, the emotional and interactional nature of patient-professional interactions around ACPs, problems in sharing decisions and preferences within and between healthcare organizations.This review demonstrates that doing more of the things that facilitate delivery of ACPs will not reduce the effects of those things that undermine them. Structured tools are only likely to be partially effective and the creation of a specialist cadre of ACP facilitators is unlikely to be a sustainable solution. The findings underscore both the challenge and need to find ways to routinely incorporate ACPs in clinical settings where multiple and competing demands impact on practice. Interventions most likely to meet with success are those that make elements of Advance Care Planning workable within complex and time pressured clinical workflows.

    Full Text Available ABSTRACT Objectives To determine the feasibility of assessing population cardiovascular risk with advanced hemodynamics in the Healthy Life in Suriname (HELISUR study. Methods This was a preliminary study conducted in May – June 2012 using the Technical-Economic-Legal-Operational-Scheduling (TELOS method to assess the feasibility of the HELISUR—a large-scale, cross-sectional population study of cardiovascular risk factors and disease in Suriname. Suriname, a middle-income country in South America with a population of mostly African and Asian ethnicity, has a high risk of cardiovascular disease. A total of 135 volunteers 18 – 70 years of age participated. A health questionnaire was tested in a primary health care center, and non-invasive cardiovascular evaluations were performed in an academic health center. The cardiovascular evaluation included sitting, supine, and standing blood pressure, and intermediate endpoints, such as cardiac output, peripheral vascular resistance, pulse wave velocity, and augmentation index. Results The TELOS testing found that communicating by cellular phone was most effective for appointment adherence, and that completion of the questionnaire often required assistance from a trained interviewer; modifications to improve the clarity of the questions are recommended. Regarding the extended cardiovascular assessments of peripheral and central hemodynamics, the findings showed these to be technically and operationally feasible and well tolerated by participants, in terms of burden and duration. Conclusions Findings of this feasibility assessment indicate that large-scale, detailed evaluations of cardiovascular risk, including a questionnaire and advanced central and peripheral hemodynamics, are feasible in a high-risk population in a middle-income setting.

    Prior observational studies suggest no additional benefit from advanced life support (ALS) when compared with providing basic life support (BLS) for patients with out-of-hospital cardiac arrest (OHCA). We compared the association of ALS care with OHCA outcomes using prospective clinical data from the Resuscitation Outcomes Consortium (ROC). Included were consecutive adults OHCA treated by participating emergency medical services (EMS) agencies between June 1, 2011, and June 30, 2015. We defined BLS as receipt of cardiopulmonary resuscitation (CPR) and/or automated defibrillation and ALS as receipt of an advanced airway, manual defibrillation, or intravenous drug therapy. We compared outcomes among patients receiving: 1) BLS-only; 2) BLS + late ALS; 3) BLS + early ALS; and 4) ALS-first care. Using multivariable logistic regression, we evaluated the associations between level of care and return of spontaneous circulation (ROSC), survival to hospital discharge, and survival with good functional status, adjusting for age, sex, witnessed arrest, bystander CPR, shockable initial rhythm, public location, EMS response time, CPR quality, and ROC site. Among 35,065 patients with OHCA, characteristics were median age 68 years (IQR 56-80), male 63.9%, witnessed arrest 43.8%, bystander CPR 50.6%, and shockable initial rhythm 24.2%. Care delivered was: 4.0% BLS-only, 31.5% BLS + late ALS, 17.2% BLS + early ALS, and 47.3% ALS-first. ALS care with or without initial BLS care was independently associated with increased adjusted ROSC and survival to hospital discharge unless delivered greater than 6 min after BLS arrival (BLS + late ALS). Regardless of when it was delivered, ALS care was not associated with significantly greater functional outcome. ALS care was associated with survival to hospital discharge when provided initially or within six minutes of BLS arrival. ALS care, with or without initial BLS care, was associated with increased ROSC, however it was

    Research has shown that increased breathing frequency during cardiopulmonary resuscitation is inversely correlated with systolic blood pressure. Rescuers often hyperventilate during cardiopulmonary resuscitation (CPR). Current American Heart Association advanced cardiac life support recommends a ventilation rate of 8-10 breaths/min. We hypothesized that a small, turbine-driven ventilator would allow rescuers to adhere more closely to advanced cardiac life support (ACLS) guidelines. Twenty-four ACLS-certified health-care professionals were paired into groups of 2. Each team performed 4 randomized rounds of 2-min cycles of CPR on an intubated mannikin, with individuals altering between compressions and breaths. Two rounds of CPR were performed with a self-inflating bag, and 2 rounds were with the ventilator. The ventilator was set to deliver 8 breaths/min, pressure limit 22 cm H 2 O. Frequency, tidal volume (V T ), peak inspiratory pressure, and compression interruptions (hands-off time) were recorded. Data were analyzed with a linear mixed model and Welch 2-sample t test. The median (interquartile range [IQR]) frequency with the ventilator was 7.98 (7.98-7.99) breaths/min. Median (IQR) frequency with the self-inflating bag was 9.5 (8.2-10.7) breaths/min. Median (IQR) ventilator V T was 0.5 (0.5-0.5) L. Median (IQR) self-inflating bag V T was 0.6 (0.5-0.7) L. Median (IQR) ventilator peak inspiratory pressure was 22 (22-22) cm H 2 O. Median (IQR) self-inflating bag peak inspiratory pressure was 30 (27-35) cm H 2 O. Mean ± SD hands-off times for ventilator and self-inflating bag were 5.25 ± 2.11 and 6.41 ± 1.45 s, respectively. When compared with a ventilator, volunteers ventilated with a self-inflating bag within ACLS guidelines. However, volunteers ventilated with increased variation, at higher V T levels, and at higher peak pressures with the self-inflating bag. Hands-off time was also significantly lower with the ventilator. (ClinicalTrials.gov registration NCT

    Physical activity (PA) improves fatigue and quality of life (QOL) in cancer survivors. Our aim was to assess whether a 2-month PA intervention improves fatigue and QOL for people with advanced lung cancer. Participants with advanced lung cancer, Eastern Cooperative Oncology Group performance status (PS) ≤2, >6 months life expectancy, and ability to complete six-min walk test, were stratified (disease stage, PS 0-1 versus 2, centre) and randomized (1:1) in an open-label study to usual care (UC) (nutrition and PA education materials) or experimental intervention (EX): UC plus 2-month supervised weekly PA and behaviour change sessions. Assessments occurred at baseline, 2, 4, and 6 months. The primary endpoint was fatigue [Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire] at 2 months. The study was designed to detect a difference in mean FACT-F subscale score of 6. Analysis was intention-to-treat using linear mixed models. We recruited 112 patients: 56 (50.4%) were randomized to EX, 55(49.5%) to UC; 1 ineligible. Male 55%; median age 64 years (34-80); 106 (96%) non-small cell lung cancer; 106 (95.5%) stage IV. At 2, 4 and 6 months, 90, 73 and 62 participants were assessed, respectively, with no difference in attrition between groups. There were no significant differences in fatigue between the groups at 2, 4 or 6 months: mean scores at 2 months EX 37.5, UC 36.4 (difference 1.2, 95% CI - 3.5, 5.8, P = 0.62). There were no significant differences in QOL, symptoms, physical or functional status, or survival. Adherence to the intervention was good but the intervention group did not increase their PA enough compared to the control group, and no difference was seen in fatigue or QOL.

    Full Text Available We investigate the extent to which advances in the health and life sciences (HLS are dependent on research in the engineering and physical sciences (EPS, particularly physics, chemistry, mathematics, and engineering. The analysis combines two different bibliometric approaches. The first approach to analyze the 'EPS-HLS interface' is based on term map visualizations of HLS research fields. We consider 16 clinical fields and five life science fields. On the basis of expert judgment, EPS research in these fields is studied by identifying EPS-related terms in the term maps. In the second approach, a large-scale citation-based network analysis is applied to publications from all fields of science. We work with about 22,000 clusters of publications, each representing a topic in the scientific literature. Citation relations are used to identify topics at the EPS-HLS interface. The two approaches complement each other. The advantages of working with textual data compensate for the limitations of working with citation relations and the other way around. An important advantage of working with textual data is in the in-depth qualitative insights it provides. Working with citation relations, on the other hand, yields many relevant quantitative statistics. We find that EPS research contributes to HLS developments mainly in the following five ways: new materials and their properties; chemical methods for analysis and molecular synthesis; imaging of parts of the body as well as of biomaterial surfaces; medical engineering mainly related to imaging, radiation therapy, signal processing technology, and other medical instrumentation; mathematical and statistical methods for data analysis. In our analysis, about 10% of all EPS and HLS publications are classified as being at the EPS-HLS interface. This percentage has remained more or less constant during the past decade.

  10. Management practices for end-of-life cathode ray tube glass: Review of advances in recycling and best available technologies.

    Cathode ray tubes are image display units found in computer monitors and televisions. In recent years, cathode ray tubes have been generated as waste owing to the introduction of newer and advanced technologies in image displays, such as liquid crystal displays and high definition televisions, among others. Generation and subsequent disposal of end-of-life cathode ray tubes presents a challenge owing to increasing volumes and high lead content embedded in the funnel and neck sections of the glass. Disposal in landfills and open dumping are anti-environmental practices considering the large-scale contamination of environmental media by the potential of toxic metals leaching from glass. Mitigating such environmental contamination will require sound management strategies that are environmentally friendly and economically feasible. This review covers existing and emerging management practices for end-of-life cathode ray tubes. An in-depth analysis of available technologies (glass smelting, detoxification of cathode ray tube glass, lead extraction from cathode ray tube glass) revealed that most of the techniques are environmentally friendly, but are largely confined to either laboratory scale, or are often limited owing to high cost to mount, or generate secondary pollutants, while a closed-looped method is antiquated. However, recycling in cementitious systems (cement mortar and concrete) gives an added advantage in terms of quantity of recyclable cathode ray tube glass at a given time, with minimal environmental and economic implications. With significant quantity of waste cathode ray tube glass being generated globally, cementitious systems could be economically and environmentally acceptable as a sound management practice for cathode ray tube glass, where other technologies may not be applicable. © The Author(s) 2015.

    To determine factors associated with case management (CM) service use in people with traumatic brain injury (TBI), using a published model for service use. A retrospective cohort, with nested case-control design. Correlational and logistic regression analyses of questionnaires from a longitudinal community data base. Questionnaires of 203 users of CM services and 273 non-users, complete for all outcome and predictor variables. Individuals with TBI, 15 years of age and older. Out of a dataset of 1,960 questionnaires, 476 met the inclusion criteria. Eight predictor variables and one outcome variable (use or non-use of the service). Predictor variables considered the framework of the Behaviour Model of Health Service Use (BMHSU); specifically, pre-disposing, need and enabling factor groups as these relate to health service use and access. Analyses revealed significant differences between users and non-users of CM services. In particular, users were significantly younger than non-users as the older the person the less likely to use the service. Also, users had less education and more severe activity limitations and lower community integration. Persons living alone are less likely to use case management. Funding groups also significantly impact users. This study advances an empirical understanding of equity of access to health services usage in the practice of CM for persons living with TBI as a fairly new area of research, and considers direct relevance to Life Care Planning (LCP). Many life care planers are CM and the genesis of LCP is CM. The findings relate to health service use and access, rather than health outcomes. These findings may assist with development of a modified model for prediction of use to advance future cost of care predictions.

    People with advanced dementia present an important target group for palliative care. They suffer a range of symptoms, and their verbal communication abilities are highly restricted. At present, little is known about their needs in the final phase of life. To identify the needs of people with advanced dementia in their final phase of life and to explore the aspects relevant to first recognize and then meet these needs. Multi-perspective qualitative study using grounded theory methodology conducting group discussions, individual interviews, and participant observation. The study encompassed nursing homes and involved health professionals, relatives, and residents with advanced dementia. Data were collected in six nursing homes. Nine group discussions and three individual interviews were conducted comprising 42 health professionals and 14 relatives. Participant observations aided in giving the perspective of 30 residents with advanced dementia. Data analysis generated a total of 25 physical, psychosocial, and spiritual needs divided into 10 categories. Physical needs were classified as follows: "food intake," "physical well-being," and "physical activity and recovery." Categories of psychosocial needs were classified as follows: "adaptation of stimuli," "communication," "personal attention," "participation," "familiarity and safety," as well as "self-determination." Spiritual needs addressed "religion." The results revealed a multitude of key aspects for recognizing and meeting these needs, stressing the importance of personhood. People with advanced dementia in their final phase of life have a multitude of individual and complex needs. This evidence contributes to narrowing the current research gap, offering an orientation framework for research and practice.

    For an effective acquisition and the practical application of rapidly increasing amounts of information, computer-based learning has already been introduced in medical education. However, there have been few studies that compare this innovative method to traditional learning methods in studying advanced cardiac life support (ACLS). Senior medical students were randomized to computer simulation and a textbook study. Each group studied ACLS for 150 minutes. Tests were done one week before, immediately after, and one week after the study period. Testing consisted of 20 questions. All questions were formulated in such a way that there was a single best answer. Each student also completed a questionnaire designed to assess computer skills as well as satisfaction with and benefit from the study materials. Test scores improved after both textbook study and computer simulation study in both groups but the improvement in scores was significantly higher for the textbook group only immediately after the study. There was no significant difference between groups in their computer skill and satisfaction with the study materials. The textbook group reported greater benefit from study materials than did the computer simulation group. Studying ACLS with a hard copy textbook may be more effective than computer simulation for the acquisition of simple information during a brief period. However, the difference in effectiveness is likely transient.

    The role of e-learning in contemporary healthcare education is quickly developing. The aim of this study was to examine the relationship between the use of an e-learning simulation programme (Microsim, Laerdal, UK) prior to attending an Advanced Life Support (ALS) course and the subsequent relationship to candidate performance. An open label, multi-centre randomised controlled study was conducted. The control group received a course manual and pre-course MCQ four weeks prior to the face to face course. The intervention group in addition received the Microsim programme on a CD. The primary outcome was performance during a simulated cardiac arrest at the end of the course. Secondary outcomes were performance during multiple choice exams, resuscitation skills assessments and feedback to Microsim programme. 572 participants were randomised (287 Microsim, 285 control). There were no significant differences in the primary outcome (performance during a standard cardiac arrest simulation) or secondary outcomes. User evaluations were favorable. 79% would recommend it to colleagues. 9% stated Microsim could replace the entire ALS course, 25% parts. Over 70% of participants' perceived that Microsim improved their understanding of the key learning domains of the ALS course. Distributing Microsim to healthcare providers prior to attending an ALS courses did not improve either cognitive or psychomotor skills performance during cardiac arrest simulation testing. The challenge that lies ahead is to identify the optimal way to use e-learning as part of a blended approach to learning for this type of training programme.

    Full Text Available Background. Critical care transfers (CCT refer to the high level of care given during transport (via ambulance, helicopter or fixed-wing aircraft of patients who are of high acuity. In South Africa (SA, advanced life support (ALS paramedics undertake CCTs. The scope of ALS in SA has no extended protocol regarding procedures or medications in terms of dealing with these CCTs. Aim. The aim of this study was to obtain the opinions of several experts in fields pertaining to critical care and transport and to gain consensus on the skills and scope-of-practice requirements of paramedics undertaking CCTs in the SA setting. Methods. A modified Delphi study consisting of three rounds was undertaken using an online survey platform. A heterogeneous sample (n=7, consisting of specialists in the fields of anaesthesiology, emergency medicine, internal medicine, critical care, critical care transport and paediatrics, was asked to indicate whether, in their opinion, selected procedures and medications were needed within the scope of practice of paramedics undertaking CCTs. Results. After three rounds, consensus was obtained in 70% (57/81 of procedures and medications. Many of these items are not currently within the scope of paramedics’ training. The panel felt that paramedics undertaking these transfers should have additional postgraduate training that is specific to critical care. Conclusion. Major discrepancies exist between the current scope of paramedic practice and the suggested required scope of practice for CCTs. An extended scope of practice and additional training should be considered for these practitioners.

    Full Text Available Aim: To investigate the quality of life (QOL of patients with advanced carcinoma esophagus treated with different palliative radiation schedules. Methods: Sixty-two consecutive patients with inoperable, non-metastatic carcinoma of the esophagus were randomly allocated to Arm-A (external radiotherapy 30 Gy/10 fractions + brachytherapy 12 Gy/two sessions, Arm-B (external radiotherapy 30 Gy /10 fractions and Arm-C (external radiotherapy 20Gy /five fractions. The QOL was assessed using the European Organization for Research and Treatment of Cancer questionnaire at presentation, after treatment and at 3 months follow-up. Results: The mean QOL score improved, in arm-A from 38 to 52 after treatment and 56 at 3 months, in arm-B from 30 to 44 after treatment and 55 at 3 months and in arm-C from 24 to 40 after treatment but decreased to 37 at 3 months. Improvement in dysphagia scores at the first follow-up was 46.1% in arm-A, 25.0% in arm-B and 22.6% in arm-C. The difference was maintained at 3 months, with maximum improvement in arm-A (57.6%. No significant differences were found between the three arms with regard to complications and additional procedures needed for relief of dysphagia. Conclusion: In comparison with external radiotherapy alone, external radiotherapy with intraluminal brachytherapy has shown a trend toward better QOL and consistent dysphagia relief without significant difference in adverse effects.

    When cardiac arrest occurs, timely competent advanced life support (ALS) interventions by nursing staff can influence patient outcomes. Ongoing ALS education influences maintenance of competency and avoids skill decay. To explore the methods of ALS education delivery for nurses in the workplace; describe the issues relating to maintaining ALS competency; explore ALS competency decay for nurses and develop recommendations for the provision of continuing ALS education. A qualitative exploratory design was used to study ALS education provision in the workplace. Data were collected from ALS nurse experts in Western Australia by face-to-face and phone interviews. Semi-structured interviews were conducted and organised around a set of predetermined questions. Two major themes were identified; the first theme Demand and Supply describes the increasing demand for ALS education for nurses and the challenges with providing timely cost effective traditional face-to-face ALS education. The second theme, Choosing The Best Education Options describes new ways to provide ALS education using emerging technologies. The study suggested that using e-learning methods would assist with educating the maximum amount of nurses in a timely manner and e-learning and teleconferencing offer opportunities to reach nurses in distant locations. Delivering ALS education more frequently than annually would increase skills maintenance and lessen skill decay. Further research is required to explore which blended e-learning model is best suited to ALS education. Copyright © 2014 Elsevier Ltd. All rights reserved.

This article describes the development and maintenance of a simulation-based medical education curriculum on advanced cardiac life support skills and its transformation to a mastery learning program. Curriculum development used the Kern 6-step model involving problem identification and general needs assessment, targeted needs assessment, goals and objectives, educational strategies, implementation, and evaluation and feedback. Curriculum maintenance and enhancement and dissemination are also addressed. Transformation of the simulation-based medical education curriculum to a mastery learning program was accomplished after a 2-year phase-in trial. A series of studies spanning 11 years was performed to adjust the curriculum, improve checklist outcome measures, and evaluate curriculum effects as learning outcomes among internal medicine residents and improved patient care practices. We anticipate wide adoption of the mastery learning model for skill and knowledge acquisition and maintenance in medical education settings.

    Advanced endovascular aortic repair can be used to treat patients with extensive and complex aortic disease who are at risk of spinal cord ischaemia. The aim of this study was to compare whether life satisfaction differs between patients with and without spinal cord ischaemia at mid-term follow-up. Nested case-control study. Among patients undergoing advanced endovascular aortic repair between 2009 and 2012, 18 patients with spinal cord ischaemia and 33 without were interviewed at home. The Life Satisfaction Questionnaire (LiSat-11) and the Satisfaction With Life Scale (SWLS) were used. LiSat-11 found that patients with spinal cord ischaemia were more dissatisfied with their activities of daily living than were patients without spinal cord ischaemia (p=0.012). Both groups had similar, very low, scores in the sexual life domain; median 2.0 (interquartile range (IQR) 1.5-3.0) and 3.0 (IQR 2.0-4.0), respectively. There was no difference in SWLS between the groups. This study cohort of patients who underwent advanced endovascular aortic repair was rather homo-genous in their rating of life satisfaction and there was little difference between mid-term survivors who had spinal cord ischaemia and those who did not.

  2. Canadian heavy water production

    1977-01-01

    The paper reviews Canadian experience in the production of heavy water, presents a long-term supply projection, relates this projection to the anticipated long-term electrical energy demand, and highlights principal areas for further improvement that form the bulk of the Canadian R and D programme on heavy water processes. Six Canadian heavy water plants with a total design capacity of 4000Mg/a are in operation or under construction. All use the Girdler-Sulphide (GS) process, which is based on deuterium exchange between water and hydrogen sulphide. Early operating problems have been overcome and the plants have demonstrated annual capacity factors in excess of 70%, with short-term production rates equal to design rates. Areas for further improvement are: to increase production rates by optimizing the control of foaming to give both higher sieve tray efficiency and higher flow rates, to reduce the incapacity due to deposition of pyrite (FeS 2 ) and sulphur (between 5% and 10%), and to improve process control and optimization of operating conditions by the application of mathematical simulations of the detailed deuterium profile throughout each plant. Other processes being studied, which look potentially attractive are the hydrogen-water exchange and the hydrogen-amine exchange. Even if they become successful competitors to the GS process, the latter is likely to remain the dominant production method for the next 10-20 years. This programme, when related to the long-term electricity demand, indicates that heavy water supply and demand are in reasonable balance and that the Candu programme will not be inhibited because of shortages of this commodity.

    People with advanced cancer face difficulties with their everyday activities at home that may reduce their health-related quality of life. To address these difficulties, we developed the 'Cancer Home-Life Intervention'. To evaluate the efficacy of the 'Cancer Home Life-Intervention' compared with usual care with regard to patients' performance of, and participation in, everyday activities, and their health-related quality of life. A randomised controlled trial ( ClinicalTrials.gov NCT02356627). The 'Cancer Home-Life Intervention' is a brief, tailored, occupational therapy-based and adaptive programme for people with advanced cancer targeting the performance of their prioritised everyday activities. Home-living adults diagnosed with advanced cancer experiencing functional limitations were recruited from two Danish hospitals. They were assessed at baseline, and at 6 and 12 weeks of follow-up. The primary outcome was activities of daily living motor ability. Secondary outcomes were activities of daily living process ability, difficulty performing prioritised everyday activities, participation restrictions and health-related quality of life. A total of 242 participants were randomised either to the intervention group ( n = 121) or the control group ( n = 121). No effect was found on the primary outcome (between-group mean change: -0.04 logits (95% confidence interval: -0.23 to 0.15); p = 0.69). Nor was any effect on the secondary outcomes observed. In most cases, the 'Cancer Home-Life Intervention' was delivered through only one home visit and one follow-up telephone contact, which not was effective in maintaining or improving participants' everyday activities and health-related quality of life. Future research should pay even more attention to intervention development and feasibility testing.

    1996-01-01

    Recent technological advances in slurry pipelining, horizontal wells, and thermal recovery techniques have made recovery of Canadian heavy oil resources more economical. In addition, reduced government royalties have made investment in these difficult reservoirs more attractive. As a result, activity has increased in heavy-oil fields in Alberta and Saskatchewan. This paper review the various oil sand recovery projects under development in the area and the current government policies which are helping to develop them. The paper also provides brief descriptions of the equipment and technologies that have allowed a reduced cost in the development. Items discussed include surface mining techniques, horizontal drilling, reservoir engineering techniques, separation processes, and thermal recovery

  7. A Canadian perspective on environmental issues

    International Nuclear Information System (INIS)

    Emmett, B.

    1993-01-01

    The leading environmental concerns in Canada are acid rain, ozone depletion, toxic substances, climate change, and biodiversity. These concerns have a number of elements in common, including a need for international actions for their solution, a high degree of scientific complexity, long life cycles from a policy point of view, and large differences in priorities between developing and developed countries. Canadians have favorable attitudes toward sustainable development and expect government and industry to be active in protecting the environment. Canadians also demand and expect a secure supply of competitively priced energy. Although industry may be concerned that incorporating environmental considerations into their business may impede competitiveness, this view is shown to be unsound for the following reasons: productivity is closely linked to a healthy environment; pollution prevention is less costly than cleanup; environmental protection can create new business opportunities; and the market is demanding more environmentally friendly industries. In the energy sector, a number of successful initiatives are under way to integrate environmental considerations into their decision making. The challenge is for industries to go beyond individual activities and build a case for sustainable energy development. The role of government includes informing Canadians about environmental risks and government priorities, ensuring that environmental assessment rules are clear and fair, streamlining regulatory processes, and using a balanced mix of legislation and regulation with market-based approaches to environmental protection

    Dyne, P.J.

    1976-01-01

    The Canadian geologic isolation program is directed at examining the potential of (1) salt deposits and (2) hard rock as repositories for radioactive wastes. It was felt essential from the inception that alternative host rocks be evaluated over a fairly large geographical area. The studies on salt deposits to date are based on existing geological information and have identified the areas that show some potential and merit further study. The factors considered include depth, thickness and purity of the deposit, overlying aquifers, and the potential for gas and oil exploration as well as potash recovery. The studies on hard rock are restricted to plutonic igneous rocks in the Ontario part of the Canadian Shield. Because geological information on their nature and extent is sparse, the study is limited to bodies that are well exposed and for which information is available.for which information is available. Field studies in the next two seasons are aimed at mapping the fault and joint patterns and defining the geologic controls on their development. In 1977 and 1978, two or three of the more favorable sites will be mapped in greater detail, and an exploratory drilling program will be established to determine the extent of fracturing at depth and the hydrology of these fractures. Conceptual designs of mined repositories in hard rock are also being made with the hope of identifying, at an early stage in this program, special problems in hard-rock repositories that may require development and study

    Although patients want to participate in discussions and decisions about their end-of-life care, studies show that providers frequently fail to invite them to explore advanced care preferences or goals for living. The purpose of our demonstration project was to provide education and coaching to individuals, health providers, and organizations across the state of Indiana intended to facilitate these conversations, documenting and honoring individuals' life goals and preferences for care during the final stages of life. Education and training engaged community members as well as healthcare providers to: (1) improve participant comfort and facility discussing end-of-life issues; (2) improve knowledge of healthcare choices, including palliative and hospice care; and (3) prepare all participants to explore and document personal values, life goals, and priorities as well as goals of care. Between January of 2013 and June of 2015, the team educated close to 5,000 participants. Participants' ratings of the quality and perceived usefulness of the educational events ranged from 4 to 5 (using a 5-point scale, with 5 = most effective). Participant comments were overwhelmingly favorable and indicated an intention to put the advance care planning resources, communication skills, knowledge of palliative and hospice care, and personal renewal techniques into practice. Participant motivation to foster advance care planning, discussions of palliative care, and end-of-life conversations was facilitated by the reframing of these conversations as identifying goals of care and priorities for living well during an important stage of life. Successful strategies included helping providers and patients to adopt a broader meaning for "sustaining hope" (not for cure, but for engaging in highly valued activities), developing provider communication skills and comfort in initiating potentially difficult discussions, engaging a new community health workforce who will develop trusting

  14. 2003 Canadian Asthma Consensus Guidelines Executive Summary

    2006-03-01

    Full Text Available Abstract Background Guidelines for the diagnosis and management of asthma have been published over the last 15 years; however, there has been little focus on issues relating to asthma in childhood. Since the last revision of the 1999 Canadian Asthma Consensus Report, important new studies, particularly in children, have highlighted the need to incorporate new information into the asthma guidelines. The objectives of this article are to review the literature on asthma published between January 2000 and June 2003 and to evaluate the influence of new evidence on the recommendations made in the 1999 Canadian Asthma Consensus Report and its 2001 update, with a major focus on pediatric issues. Methods The diagnosis of asthma in young children and prevention strategies, pharmacotherapy, inhalation devices, immunotherapy, and asthma education were selected for review by small expert resource groups. The reviews were discussed in June 2003 at a meeting under the auspices of the Canadian Network For Asthma Care and the Canadian Thoracic Society. Data published through December 2004 were subsequently reviewed by the individual expert resource groups. Results This report evaluates early-life prevention strategies and focuses on treatment of asthma in children, emphasizing the importance of early diagnosis and preventive therapy, the benefits of additional therapy, and the essential role of asthma education. Conclusion We generally support previous recommendations and focus on new issues, particularly those relevant to children and their families. This document is a guide for asthma management based on the best available published data and the opinion of health care professionals, including asthma experts and educators.

  15. Medical cannabis - the Canadian perspective.

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

    2016-01-01

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

    Few interventions have focused on improving end-of-life care for underserved populations, such as homeless persons. To determine whether homeless persons will complete a counseling session on advance care planning and fill out a legal advance directive designed to assess care preferences and preserve the dignity of marginalized persons. Prospective, single-blind, randomized trial comparing self-guided completion of an advance directive with professionally assisted advance care planning. (ClinicalTrials.gov registration number: NCT00546884) 8 sites serving homeless persons in Minneapolis, Minnesota. 262 homeless persons recruited between November 2007 and August 2008. Minimal, self-guided intervention consisting of advance directive forms and written educational information versus a one-on-one advance planning intervention consisting of counseling and completing an advance directive with a social worker. Rate of advance directive completion, assessed by inspection of completed documents. The overall completion rate for advance directives was 26.7% (95% CI, 21.5% to 32.5%), with a higher rate in the counselor-guided group (37.9%) than in the self-guided group (12.8%) (CI of adjusted difference, 15.3 to 34.3 percentage points). This difference persisted across all sites and most subgroups. The advance directive's 4 clinical scenarios found a preference for surrogate decision making in 29% to 34% of written responses. Sampling was limited to a more stable subset of the homeless population in Minneapolis and may have been subject to selection bias. Modest compensation to complete the preintervention survey could have influenced participants to complete advance directives. Both a simple and complex intervention successfully engaged a diverse sample of homeless persons in advance care planning. One-on-one assistance significantly increased the completion rate. Homeless persons can respond to an intervention to plan for end-of-life care and can express specific preferences

    The purpose of the study was to determine whether treatment preferences in patients' advance directives (ADs) are associated with life-supporting treatments received during end-of-life care in the intensive care unit (ICU). This is a retrospective cohort study, including patients who died in 4 ICUs of a university hospital in Germany. Patients with ADs were matched with 2 patients each without ADs using propensity scores. Sixty-four (13%) of 477 patients had ADs, written a median of 109 weeks before admission. Five categories of applicability conditions were identified, most of them difficult to interpret in the ICU (eg, "advanced brain impairment" or "imminent death"). Advance directives contained a number of treatment refusals. Specifically, 63 of 64 refused "life-sustaining measures." Compared to patients without ADs, patients with ADs were less likely to receive cardiopulmonary resuscitation (9% vs 23%, P = .029) and more likely to have do-not-resuscitate orders (77% vs 56%, P = .007). Therapy-limiting decisions and ICU length of stay did not differ between those with or without ADs. Patients with ADs are less likely to receive cardiopulmonary resuscitation but otherwise receive similar life-sustaining treatments compared to matched patients without ADs. More research is needed to explore reasons for potential noncompliance with patient preferences. © 2013.

  20. Effectiveness of beneficial plant-microbe interactions under hypobaric and hypoxic conditions in an advanced life support system

    Science.gov (United States)

    MacIntyre, Olathe; Stasiak, Michael; Cottenie, Karl; Trevors, Jack; Dixon, Mike

    An assembled microbial community in the hydroponics solution of an advanced life support system may improve plant performance and productivity in three ways: (1) exclusion of plant pathogens from the initial community, (2) resistance to infection, and (3) plant-growth promotion. However, the plant production area is likely to have a hypobaric (low pressure) and hypoxic (low oxygen) atmosphere to reduce structural mass and atmosphere leakage, and these conditions may alter plant-microbe interactions. Plant performance and productivity of radish (Raphanus sativus L. cv. Cherry Bomb II) grown under hypobaric and hypoxic conditions were investigated at the University of Guelph's Controlled Environment Systems Research Facility. Changes in the microbial communities that routinely colonized the re-circulated nutrient solution, roots, and leaves of radishes in these experiments were quantified in terms of similarity in community composition, abundance of bacteria, and community diversity before and after exposure to hypobaric and hypoxic conditions relative to communities maintained at ambient growth conditions. The microbial succession was affected by extreme hypoxia (2 kPa oxygen partial pressure) while hypobaria as low as 10 kPa total pressure had little effect on microbial ecology. There were no correlations found between the physiological profile of these unintentional microbial communities and radish growth. The effects of hypobaric and hypoxic conditions on specific plant-microbe interactions need to be determined before beneficial gnotobiotic communities can be developed for use in space. The bacterial strains Tal 629 of Bradyrhizobium japonicum and WCS417 of Pseudomonas fluorescens, and the plant pathogen Fusarium oxysporum f. sp. raphani will be used in future experiments. B. japonicum Tal 629 promotes radish growth in hydroponics systems and P. fluorescens WCS417 induces systemic resistance to fusarium wilt (F. oxysporum f. sp. raphani) in radish under ambient

  1. Advanced steam power plant concepts with optimized life-cycle costs: A new approach for maximum customer benefit

    Energy Technology Data Exchange (ETDEWEB)

    Seiter, C.

    1998-07-01

    The use of coal power generation applications is currently enjoying a renaissance. New highly efficient and cost-effective plant concepts together with environmental protection technologies are the main factors in this development. In addition, coal is available on the world market at attractive prices and in many places it is more readily available than gas. At the economical leading edge, standard power plant concepts have been developed to meet the requirements of emerging power markets. These concepts incorporate the high technological state-of-the-art and are designed to achieve lowest life-cycle costs. Low capital cost, fuel costs and operating costs in combination with shortest lead times are the main assets that make these plants attractive especially for IPPs and Developers. Other aspects of these comprehensive concepts include turnkey construction and the willingness to participate in BOO/BOT projects. One of the various examples of such a concept, the 2 x 610-MW Paiton Private Power Project Phase II in Indonesia, is described in this paper. At the technological leading edge, Siemens has always made a major contribution and was pacemaker for new developments in steam power plant technology. Modern coal-fired steam power plants use computer-optimized process and plant design as well as advanced materials, and achieve efficiencies exceeding 45%. One excellent example of this high technology is the world's largest lignite-fired steam power plant Schwarze Pumpe in Germany, which is equipped with two 800 MW Siemens steam turbine generators with supercritical steam parameters. The world's largest 50-Hz single-shaft turbine generator with supercritical steam parameters rated at 1025 MW for the Niederaussem lignite-fired steam power plant in Germany is a further example of the sophisticated Siemens steam turbine technology and sets a new benchmark in this field.

    Full Text Available Abstract Background The aim of this study was to measure chest compression decay during simulated advanced life support (ALS in a cardiac arrest manikin model. Methods 19 paramedic teams, each consisting of three paramedics, performed ALS for 12 minutes with the same paramedic providing all chest compressions. The patient was a resuscitation manikin found in ventricular fibrillation (VF. The first shock terminated the VF and the patient remained in pulseless electrical activity (PEA throughout the scenario. Average chest compression depth and rate was measured each minute for 12 minutes and divided into three groups based on chest compression quality; good (compression depth ≥ 40 mm, compression rate 100-120/minute for each minute of CPR, bad (initial compression depth 120/minute or decay (change from good to bad during the 12 minutes. Changes in no-flow ratio (NFR, defined as the time without chest compressions divided by the total time of the ALS scenario over time was also measured. Results Based on compression depth, 5 (26%, 9 (47% and 5 (26% were good, bad and with decay, respectively. Only one paramedic experienced decay within the first two minutes. Based on compression rate, 6 (32%, 6 (32% and 7 (37% were good, bad and with decay, respectively. NFR was 22% in both the 1-3 and 4-6 minute periods, respectively, but decreased to 14% in the 7-9 minute period (P = 0.002 and to 10% in the 10-12 minute period (P Conclusions In this simulated cardiac arrest manikin study, only half of the providers achieved guideline recommended compression depth during prolonged ALS. Large inter-individual differences in chest compression quality were already present from the initiation of CPR. Chest compression decay and thereby fatigue within the first two minutes was rare.

  3. Spacesuit Water Membrane Evaporator; An Enhanced Evaporative Cooling System for the Advanced Extravehicular Mobility Unit Portable Life Support System

    2014-01-01

    Development of the Advanced Extravehicular Mobility Unit (AEMU) portable life support subsystem (PLSS) is currently under way at NASA Johnson Space Center. The AEMU PLSS features a new evaporative cooling system, the Generation 4 Spacesuit Water Membrane Evaporator (Gen4 SWME). The SWME offers several advantages when compared with prior crewmember cooling technologies, including the ability to reject heat at increased atmospheric pressures, reduced loop infrastructure, and higher tolerance to fouling. Like its predecessors, Gen4 SWME provides nominal crew member and electronics cooling by flowing water through porous hollow fibers. Water vapor escapes through the hollow fiber pores, thereby cooling the liquid water that remains inside of the fibers. This cooled water is then recirculated to remove heat from the crew member and PLSS electronics. Test results from the backup cooling system which is based on a similar design and the subject of a companion paper, suggested that further volume reductions could be achieved through fiber density optimization. Testing was performed with four fiber bundle configurations ranging from 35,850 fibers to 41,180 fibers. The optimal configuration reduced the Gen4 SWME envelope volume by 15% from that of Gen3 while dramatically increasing the performance margin of the system. A rectangular block design was chosen over the Gen3 cylindrical design, for packaging configurations within the AEMU PLSS envelope. Several important innovations were made in the redesign of the backpressure valve which is used to control evaporation. A twin-port pivot concept was selected from among three low profile valve designs for superior robustness, control and packaging. The backpressure valve motor, the thermal control valve, delta pressure sensors and temperature sensors were incorporated into the manifold endcaps, also for packaging considerations. Flight-like materials including a titanium housing were used for all components. Performance testing

    Background Medical residents are often responsible for leading and performing cardiopulmonary resuscitation; however, their levels of expertise and comfort as leaders of advanced cardiovascular life support (ACLS) teams vary widely. While the current American Heart Association ACLS course provides education in recommended resuscitative protocols, training in leadership skills is insufficient. In this article, we describe the design and implementation in our institution of a formative curriculum aimed at improving residents’ readiness for being leaders of ACLS teams using human patient simulation. Human patient simulation refers to a variety of technologies using mannequins with realistic features, which allows learners to practice through scenarios without putting patients at risk. We discuss the limitations of the program and the challenges encountered in implementation. We also provide a description of the initiation and organization of the program. Case scenarios and assessment tools are provided. Description of the Institutional Training Program Our simulation-based training curriculum consists of 8 simulated patient scenarios during four 1-hour sessions. Postgraduate year–2 and 3 internal medicine residents participate in this program in teams of 4. Assessment tools are utilized only for formative evaluation. Debriefing is used as a teaching strategy for the individual resident leader of the ACLS team to facilitate learning and improve performance. To evaluate the impact of the curriculum, we administered a survey before and after the intervention. The survey consisted of 10 questions answered on a 5-point Likert scale, which addressed residents’ confidence in leading ACLS teams, management of the equipment, and management of cardiac rhythms. Respondents’ mean presimulation (ie, baseline) and postsimulation (outcome) scores were compared using a 2-sample t test.

  5. Canadian attitudes to nuclear power

    In the past ten years, public interest in nuclear power and its relationship to the environment has grown. Although most Canadians have accepted nuclear power as a means of generating electricity, there is significant opposition to its use. This opposition has effectively forced the Canadian nuclear industry to modify its behaviour to the public in the face of growing concern over the safety of nuclear power and related matters. The paper reviews Canadian experience concerning public acceptance of nuclear power, with special reference to the public information activities of the Canadian nuclear industry. Experience has shown the need for scientific social data that will permit the nuclear industry to involve the public in a rational examination of its concern about nuclear power. The Canadian Nuclear Association sponsored such studies in 1976 and the findings are discussed. They consisted of a national assessment of public attitudes, two regional studies and a study of Canadian policy-makers' views on nuclear energy. The social data obtained were of a base-line nature describing Canadian perceptions of and attitudes to nuclear power at that time. This research established that Canadian levels of knowledge about nuclear power are very low and that there are marked regional differences. Only 56% of the population have the minimum knowledge required to indicate that they know that nuclear power can be used to generate electricity. Nevertheless, 21% of informed Canadians oppose nuclear power primarily on the grounds that it is not safe. Radiation and waste management are seen to be major disadvantages. In perspective, Canadians are more concerned with inflation than with the energy supply. About half of all Canadians see the question of energy supplies as a future problem (within five years), not a present one. A more important aspect of energy is seen by the majority of Canadians to be some form of energy independence. The use of data from these studies is no easy

    A study was conducted in 4 Canadian processing plants in 1995-96 to determine the prevalence of quality defects in Canadian cattle. One percent of the annual number of cattle processed in Canada were evaluated on the processing floor and 0.1% were graded in the cooler. Brands were observed on 37% and multiple brands on 6% of the cattle. Forty percent of the cattle had horns, 20% of which were scurs, 33% were stubs, 10% were tipped, and 37% were full length. Tag (mud and manure on the hide) was observed on 34% of the cattle. Bruises were found on 78% of the carcasses, 81% of which were minor in severity. Fifteen percent of the bruises were located on the round, 29% on the loin, 40% on the rib, 16% on the chuck, and 0.02% on the brisket. Grubs were observed in 0.02% of the steers, and injection sites were observed in 1.3% of whole hanging carcasses. Seventy percent of the livers were passed for human food and 14% for pet food; 16% were condemned. Approximately 71% of the liver condemnations were due to liver abscesses. Four percent of the heads, 6% of the tongues, and 0.2% of whole carcasses were condemned. The pregnancy rate in female cattle was approximately 6.7%. The average hot carcass weight was 357 kg (s = 40) in steers, 325 kg (s = 41) in heifers, 305 kg (s = 53) in cows, 388 kg (s = 62) in virgin bulls and 340 kg (s = 39) in mature bulls. The average ribeye area in all cattle was 84 cm2 (s = 12); range 29 cm2 to 128 cm2. Grade fat was highly variable and averaged 9 mm (s = 4) for steers and heifers, 6 mm (s = 6) for cows, 5 mm (s = 1) for virgin bulls, and 4 mm (s = 0.5) for mature bulls. The average lean meat yield was 59.7% in cattle (s = 3.4); range 39% to 67%. One percent of the carcasses were devoid of marbling, 1% were dark cutters, and 0.05% of the steer carcasses were staggy. Six percent of the carcasses had poor conformation, 3.7% were underfinished, and 0.7% were overfinished. Yellow fat was observed in 4% of the carcasses; 10% of carcasses were

    Several aspects of recent work at the National Research Council of Canada on the development of vertical-axis turbines have been reviewed. Most of this work, during the past year or more, has been in support of the design of a 200 kW unit now being built for experimental operation on the Magdelen Islands in the Gulf of St. Lawrence. Results of small and large scale aeroelastic wind tunnel model experiments have confirmed that very large scale vertical-axis wind turbines are feasible, especially if designed for normal operation at constant rotational speed. A computer model of a simple mixed power system has indicated that substantial cost savings may be possible by using wind energy in Canadian east coast regions. 4 refs., 11 figs., 1 tab.

    Background and purpose: The relation between health-related quality of life (HRQOL) and survival was investigated at baseline and 6 months in 80 patients with advanced oral or oropharyngeal cancer after microvascular reconstructive surgery and (almost all) adjuvant radiotherapy. Materials and methods: Multivariate Cox regression analyses of overall and disease-specific survival were performed including sociodemographic (age, gender, marital status, comorbidity), and clinical (tumor stage and site, radical surgical, metastasis, radiotherapy) parameters, and HRQOL (EORTC QLQ-C30 global quality of life scale). Results: Before treatment, younger age and having a partner were predictors of disease-specific survival; younger age predicted overall survival. At 6 months post-treatment, disease-specific and overall survival was predicted by (deterioration of) global quality of life solely. Global health-related quality of life after treatment was mainly influenced by emotional functioning. Conclusion: Deterioration of global quality of life after treatment is an independent predictor of survival in patients with advanced oral or oropharyngeal cancer.

    1978-08-01

    To identify the times of emergence of the permanent teeth of Canadian Eskimos (Inuit), 368 children and adolescents were examined. The presence or absence of all permanent teeth except the third molars was recorded and these data subjected to probit analysis. Female emergence times were advanced over males. Generally, the Inuit of both sexes showed statistically significant earlier emergence times than Montreal children, except for the incisors. The present results do not support hypotheses indicating that premature extraction of the deciduous teeth advances the emergence of their succedaneous counterparts. There is some indication the controls of deciduous tooth emergence continue to play some part in emergence of the permanent dentition, especially the first permanent teeth that emerge.

    This research report presents findings on 'start in life' from a qualitative study of 90-year-olds from the Lothian Birth Cohort 1921. The study aimed to contextualise the LBC1921 cohort in time and place, describe cohort members' experiences of family and schooling and stimulate further inquiry into the relationships between 'start in life' and risk and resilience factors relating to longevity and healthy ageing. Scottish education and family life in the early 1930s are briefly described. Life review questionnaire: A qualitative Life Review Questionnaire was developed, requiring free-text handwritten responses. Its 'Start in Life' section focused on schooling and family support. Wave 4 of the Lothian Birth Cohort 1921 involved testing 129 members near to their 90(th) birthday. They reside largely in Edinburgh and its environs. The Life Review Questionnaire was administered to 126 participants, 54 % women. Qualitative analysis: Thematic analysis was the qualitative technique used to categorise, code and extract meaning from questionnaire text. Narratives were extracted from the data to present illustrative stories. Narratives of start in life gave contextual description. Thematic analysis showed LBC1921 members enjoying their schooling, highlighting teachers, academic achievement, school activities and school friendships. Personal qualities, family circumstances and aspects of schooling sometimes hindered educational performance. Family life was recalled mostly with warmth and parents were often portrayed as valuing education and supporting learning and development. Family adversity from poverty, parental illness and parental death was often mitigated by support from parents (or the remaining parent). Overall, most cohort members believed that they had got off to a good 'start in life'. This qualitative investigation of 'start in life' adds context and richness to quantitative investigations of the sizeable LBC1921 cohort, stimulating fresh insights and hypotheses

    In light of prior reports on the prevalence of stress, depression, and other mental health problems among physicians in training and practice, we examined the mental health concerns of Canadian physicians using data from the 2007-2008 Canadian Physician Health Study. Among 3213 respondents, 5 variables (depressive symptoms during the past year, anhedonia in the past year, mental health concerns making it difficult to handle one's workload in the past month, problems with work-life balance, and poor awareness of resources for mental health problems) were examined in relation to sex, specialty, practice type (solo practice vs group or other practice settings), and practice setting (inner city, urban/suburban, or rural/small town/remote). Nearly one quarter of physicians reported a 2-week period of depressed mood, and depression was more common among female physicians and general practitioners/family physicians. Anhedonia was reported by one fifth; anesthesiologists were most likely to report anhedonia, followed by general practitioners/family physicians. More than one quarter reported mental health concerns making it difficult to handle their workload, which was more common among female physicians and general practitioners/family physicians and psychiatrists. Nearly one quarter reported poor work-life balance. Lack of familiarity with mental health resources was problematic, which was more prominent among female physicians and specialists outside of general practice/family medicine or psychiatry. Mental health concerns are relatively common among Canadian physicians. Training programs and programmatic/policy enhancements should redouble efforts to address depression and other mental health concerns among physicians for the benefit of the workforce and patients served by Canadian physicians.

  14. A model for emergency department end-of-life communications after acute devastating events--part I: decision-making capacity, surrogates, and advance directives.

    Making decisions for a patient affected by sudden devastating illness or injury traumatizes a patient's family and loved ones. Even in the absence of an emergency, surrogates making end-of-life treatment decisions may experience negative emotional effects. Helping surrogates with these end-of-life decisions under emergent conditions requires the emergency physician (EP) to be clear, making medical recommendations with sensitivity. This model for emergency department (ED) end-of-life communications after acute devastating events comprises the following steps: 1) determine the patient's decision-making capacity; 2) identify the legal surrogate; 3) elicit patient values as expressed in completed advance directives; 4) determine patient/surrogate understanding of the life-limiting event and expectant treatment goals; 5) convey physician understanding of the event, including prognosis, treatment options, and recommendation; 6) share decisions regarding withdrawing or withholding of resuscitative efforts, using available resources and considering options for organ donation; and 7) revise treatment goals as needed. Emergency physicians should break bad news compassionately, yet sufficiently, so that surrogate and family understand both the gravity of the situation and the lack of long-term benefit of continued life-sustaining interventions. EPs should also help the surrogate and family understand that palliative care addresses comfort needs of the patient including adequate treatment for pain, dyspnea, or anxiety. Part I of this communications model reviews determination of decision-making capacity, surrogacy laws, and advance directives, including legal definitions and application of these steps; Part II (which will appear in a future issue of AEM) covers communication moving from resuscitative to end-of-life and palliative treatment. EPs should recognize acute devastating illness or injuries, when appropriate, as opportunities to initiate end-of-life discussions and to

  15. The Canadian Dollar and the Dutch and Canadian Diseases

    2013-10-01

    Full Text Available With the spectacular rise of the dollar, along with rising natural-resource prices during the first decade of the 21st century, Canadians heard a great deal about Dutch disease. Many politicians and pundits blamed the phenomenon — in which a country’s currency, inflated by rising commodity prices, renders manufacturing exports increasingly uncompetitive — for rising unemployment in the Canadian manufacturing industry. But a close look at what happened during that period reveals that the Dutch disease mechanism was only part of the story. The other part, and quantitatively the most important, is an affliction of an altogether different providence: Canadian disease. Canadian disease is the economic trouble that can be caused by Canada’s extraordinarily heavy reliance on the United States as a trading partner. As a consequence, a sudden depreciation of the U.S, dollar will deteriorate the competitiveness of Canadian manufacturing exporters. Such a phenomenon was at work during the “Great Appreciation” of the Canadian dollar between 2002 and 2008 — the largest such appreciation on record in this country. The depreciation of the U.S. dollar is a phenomenon that is independent of the resource boom and the resulting consequences on the Canadian economy cannot be endorsed to a Dutch disease. Almost 2/3 of the employment losses that are exchange rate related in the trade-exposed manufacturers in Canada during the 2002–2008 period could be attributed to the Canadian disease. The Canadian dollar is partly driven by commodity prices, and the appreciation of the Canadian dollar exerts a negative impact on manufacturing industries that are exposed to international competition. This phenomenon can be coined as a Dutch Affair. The Dutch Affair becomes a disease in the long run when the non-renewable resource is depleted and the manufacturing base is gone. New manufacturing activities might not reappear due to a variety of obstacles. In Canada

    Full Text Available High-fidelity simulation (HFS is a learning method which has proven effective in medical education for technical and non-technical skills. However, its effectiveness for knowledge acquisition is less validated. We performed a randomized study with the primary aim of investigating whether HFS, in association with frontal lessons, would improve knowledge about advanced life support (ALS, in comparison to frontal lessons only among medical students. The secondary aims were to evaluate the effect of HFS on knowledge acquisition of different sections of ALS and personal knowledge perception. Participants answered a pre-test questionnaire consisting of a subjective (evaluating personal perception of knowledge and an objective section (measuring level of knowledge containing 100 questions about algorithms, technical skills, team working/early warning scores/communication strategies according to ALS guidelines. All students participated in 3 frontal lessons before being randomized in group S, undergoing a HFS session, and group C, receiving no further interventions. After 10 days from the end of each intervention, both groups answered a questionnaire (post-test with the same subjective section but a different objective one. The overall number of correct answers of the post-test was significantly higher in group S (mean 74.1, SD 11.2 than in group C (mean 65.5, SD 14.3, p = 0.0017, 95% C.I. 3.34 - 13.9.

    Increased dependence on Western diets and low physical activity have largely contributed to weight gain and associated chronic diseases in the Canadian Inuit population. The purpose of this study was to systematically review factors influencing dietary and physical activity behaviors to guide health promotion interventions and provide recommendations for future studies. We conducted a systematic literature review to identify relevant articles. Searches were conducted between May 2014 and July 2014, and inclusive of articles published up until July 2014. Articles were searched using four databases: PubMed, PsycINFO, SocINDEX, and Psychology and Behavioral Sciences Collection. Eligible studies focused on diet and/or physical activity or determinants of diet and/or physical activity in Canadian Inuit population, and were published in English. A total of 45 articles were included in the analysis. A detailed appraisal of the articles suggested that many Inuit have disconnected from the traditional ways of life, including harvesting and processing of traditional food species and the associated physical activity. In the last two decades there has been a significant shift from consumption of healthy traditional foods to energy-dense store-bought foods particularly among younger Inuit (Inuit. However, our understanding is limited on how these behaviours might be influenced in the face of these changes. Prospective studies are needed to advance our knowledge of cognitive and environmental determinants of Inuit energy balance-related behaviours. These studies can inform the development of health promotion interventions in the population.

    In a severe accident, hydrogen is released into containment. When it is well mixed, the hydrogen mixture is nonflammable because there is sufficient dilution by the large containment volume. This is the desired end point. However, the release may occur into smaller compartments of containment, stratification may occur, and local pockets of flammable mixtures may arise if hydrogen is released faster than processes that mix and disperse it. Long term hydrogen generation from water radiolysis must also be considered. Hydrogen mitigation and control strategies adopted or considered in Canada include fanforced mixing, glow plug igniters, recombiners, venting through filters, or combinations of these. The Canadian hydrogen programme is focussed on understanding hydrogen combustion behaviour and providing the data needed to demonstrate the adequacy of hydrogen mitigation and control strategies. The programme includes both experimental and modelling components of hydrogen combustion and distribution. Experiments include mixing tests, deflagration tests, diffusion flames, transition from deflagration to detonation, and testing the performance of igniters and recombiners. Modelling is focussing on the GOTHIC code as an industry standard. Detailed three dimensional modelling of gas mixing and combustion are underway, and a code validation matrix is being assembled for validation exercises. Significant progress has been made, highlights from which are being presented at this workshop. (author)

    Refractory angina (RFA) is a debilitating disease characterized by cardiac pain resistant to conventional treatments for coronary artery disease including nitrates, calcium-channel and β-adrenoceptor blockade, vasculoprotective agents, percutaneous coronary interventions, and coronary artery bypass grafting. The mortality rate of patients living with RFA is not known but is thought to be in the range of approximately 3%. These individuals suffer severely impaired health-related quality of life with recurrent and sustained pain, poor general health status, psychological distress, impaired role functioning, and activity restriction. Effective care for RFA sufferers in Canada is critically underdeveloped. These guidelines are predicated upon a 2009 Canadian Cardiovascular Society (CCS) Position Statement which identified that underlying the problem of RFA management is the lack of a formalized, coordinated, interprofessional strategy between the cardiovascular and pain science/clinical communities. The guidelines are therefore a joint initiative of the CCS and the Canadian Pain Society (CPS) and make practice recommendations about treatment options for RFA that are based on the best available evidence. Concluding summary recommendations are also made, giving direction to future clinical practice and research on RFA management in Canada. Copyright © 2012 Canadian Cardiovascular Society.

    Highlights: ► The application of advanced validation techniques (sensitivity, calibration and prediction) to nuclear performance codes FRAPCON and LIFE-4 is the focus of the paper. ► A sensitivity ranking methodology narrows down the number of selected modeling parameters from 61 to 24 for FRAPCON and from 69 to 35 for LIFE-4. ► Fuel creep, fuel thermal conductivity, fission gas transport/release, crack/boundary, and fuel gap conductivity models of LIFE-4 are identified for improvements. ► FRAPCON sensitivity results indicated the importance of the fuel thermal conduction and the fission gas release models. -- Abstract: Evolving nuclear energy programs expect to use enhanced modeling and simulation (M and S) capabilities, using multiscale, multiphysics modeling approaches, to reduce both cost and time from the design through the licensing phases. Interest in the development of the multiscale, multiphysics approach has increased in the last decade because of the need for predictive tools for complex interacting processes as a means of eliminating the limited use of empirically based model development. Complex interacting processes cannot be predicted by analyzing each individual component in isolation. In most cases, the mathematical models of complex processes and their boundary conditions are nonlinear. As a result, the solutions of these mathematical models often require high-performance computing capabilities and resources. The use of multiscale, multiphysics (MS/MP) models in conjunction with high-performance computational software and hardware introduces challenges in validating these predictive tools—traditional methodologies will have to be modified to address these challenges. The advanced MS/MP codes for nuclear fuels and reactors are being developed within the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program of the US Department of Energy (DOE) – Nuclear Energy (NE). This paper does not directly address challenges in calibration

    The Advanced Pediatric Life Support (APLS) course was introduced in the training of professionals who care for pediatric emergencies in Spain in 2005. To analyze the impact of the APLS course in the current clinical practice in Spanish PEDs. The directors of APLS courses were asked about information regarding the courses given to date, especially on the results of the satisfaction survey completed by students at the end of the course. Furthermore, in December 2014, a survey was conducted through Google Drive, specifically asking APLS students about the usefulness of the APLS course in their current clinical practice. In the last 10 years since the APLS course was introduced in Spain, there have been 40 courses in 6 different venues. They involved a total of 1520 students, of whom 958 (63.0%) felt that the course was very useful for daily clinical practice. The survey was sent to 1,200 students and answered by 402 (33.5%). The respondent group most represented was pediatricians, 223 (55.5%), of whom 61 (27.3%) were pediatric emergency physicians, followed by pediatric residents, 122 (30.3%). One hundred three (25.6%) respondents had more than 10 years of professional practice and 291 (72.4%) had completed the course in the preceding four years. Three hundred forty-one of the respondents (84.9%: 95% confidence interval [CI], 81.9-87.9) said that they always use the pediatric assessment triangle (PAT) and 131 (32.6%: 95% CI, 28-37.1) reported that their organization has introduced this tool into their protocols. Two hundred twenty-three (55.5%: 95% CI, 50.6-60.3) believed that management of critically ill patients has improved, 328 (81.6%: 95% CI, 77.8-85.3) said that the PAT and the systematic approach, ABCDE, help to establish a diagnosis, and 315 (78.4%: 95% CI, 74.3-82.4) reported that the overall number of treatments has increased but that these treatments are beneficial for patients. Hospital professionals (191; 47.5%) include the PAT in their protocols more

    Although currently many advanced colorectal cancer patients continuously receive chemotherapy, there are very few findings with regard to the supportive care needs of such patients. The purposes of this study were to investigate the patients' perceived needs and the association with psychological distress and/or quality of life, and to clarify the characteristics of patients with a high degree of unmet needs. Ambulatory colorectal cancer patients who were receiving chemotherapy were asked to complete the Short-Form Supportive Care Needs Survey questionnaire, which covers five domains of need (health system and information, psychological, physical, care and support, and sexuality needs), the Hospital Anxiety and Depression Scale and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. Complete data were available for 100 patients. Almost all of the top 10 most common unmet needs belonged to the psychological domain. The patients' total needs were significantly associated with both psychological distress (r = 0.65, P quality of life (r = -0.38, P patients' needs and psychological distress and/or quality of life suggest that interventions that respond to patients' needs may be one possible strategy for ameliorating psychological distress and enhancing quality of life. Female patients' needs should be evaluated more carefully. © The Author 2017. Published by Oxford University Press. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

    Family caregivers (broadly defined as family and friends) experience multiple concurrent transitions when caring for a person with advanced cancer. To (a) explore the transition experience of family caregivers caring for persons with advanced cancer living in the community, (b) describe potential triggers for transitions, (c) identify what influences this experience, and (d) develop a conceptual framework of their transition experience. Sandelowski and Barroso's methodology for synthesizing qualitative research included (a) a comprehensive search of empirical literature, (b) quality appraisal of qualitative studies, (c) classification of studies, and (d) synthesis of the findings. Literature was sourced from six electronic data bases. Inclusion criteria were as follows: (a) published qualitative studies (and mixed-method designs) of the caregiving experience of family caregivers of community-living persons with advanced cancer at the end of life, (b) participants (caregivers and care recipients) of 18 years of age and above, (c) studies published in English in any country, and (d) studies published between 2004 and 2014. A total of 72 studies were included in the metasynthesis. Family caregivers experience a "life transition" whereby their lives are permanently altered. The participants described the process of redefining normal which consisted of coming to terms with their situation and connecting with others. Outcomes of these processes were as follows: (a) maintaining a sense of personhood, (b) reframing hope, (c) maintaining self-efficacy, (d) finding meaning, and (e) preparing for the death of their care recipient. The findings provide a framework to guide the development of supportive programs and future research.

    Full Text Available Postsurgical survival is considered to be indicators of treatment efficiency in most cases. However, the sociomedical rehabilitation of patients in this group is no less important; not only life expectancy, but also functional rehabilitation and quality of life are in the lead in patients with Stage III–IVA due to their low 2-year and much lower 5-year survival. The main efficiency criterion is patients, quality of life as compared to antitumor treatment programs in the absence of differences in survival.As the only chance of cure or life prolongation in most cases, multicomponent surgery for locally advanced and recurrent oropharyngeal cancer may be refused by a patient for fear of being lost to society. Identification of surgical treatment-induced changes in quality of life in patients may be used as a criterion for assessing the performed operations.The body's changes in a patient with otopharyngeal cancer are associated with impairment of basic physiological functions (deglutition, mastication, and breathing, sensitivity (taste, olfaction, and hearing, and individual characteristics of a human being (for example, appearance and voice. The quality of life is integral characteristics of the physical, psychological, emotional, and social functioning of a patient, which is based on his subjective perception. The methods for studying the quality of life include first of all questionnaires that are classified as general and special ones.The general questionnaires are intended to assess the quality of life of both healthy individuals and patients regardless of their disease; the special questionnaires are used to study that in certain categories and groups of patients. The general questionnaires allow the comparison of patients with a population of healthy people. Account must be also taken of the fact that the quality of life varies with age and comorbidities. A great deal of procedures for measuring the quality of life in different groups of

    Efforts to promote the completion of advance directives implicitly assume that completion rates of these documents, which help ensure care consistent with people's preferences in the event of incapacity, are undesirably low. However, data regarding completion of advance directives in the United States are inconsistent and of variable quality. We systematically reviewed studies published in the period 2011-16 to determine the proportion of US adults with a completed living will, health care power of attorney, or both. Among the 795,909 people in the 150 studies we analyzed, 36.7 percent had completed an advance directive, including 29.3 percent with living wills. These proportions were similar across the years reviewed. Similar proportions of patients with chronic illnesses (38.2 percent) and healthy adults (32.7 percent) had completed advance directives. The findings provide benchmarks for gauging future policies and practices designed to motivate completion of advance directives, particularly among those people most likely to benefit from having these documents on record.

    This study aims to identify domains of quality of life (QoL) that are culturally relevant to Chinese caregivers of advanced cancer patients in Singapore and to evaluate content adequacy of currently available instruments for use in the target population. English- and Chinese-speaking caregivers of advanced cancer patients receiving care under a tertiary cancer center and/or a community hospice home care/day care provider were recruited for in-depth interviews. The interviews were analyzed using thematic analysis. The identified domains, themes and sub-themes were compared to concepts addressed by items from five existing cancer-specific caregiver QoL instruments. Eighteen female and eight male caregivers aged 28-74 years participated in the study. Twenty-nine QoL themes and 59 sub-themes were identified in six domains, namely physical health, mental health, social health, spiritual health, financial health and daily life. Collectively, but not individually, the content of the five existing instruments adequately cover the physical health domain, social health domain and some themes on mental health domain for the study population. Content gaps were identified in the domains of mental health, spiritual health, daily life and financial health. The present study found culturally and contextually specific themes and sub-themes about positive emotional health, spiritual health and financial health.

    Dementia is a terminal illness, and family caregivers play a vital role in providing end-of-life care to their relative. The present study begins to address the paucity of research regarding end-of-life caregiving experience with dementia. This study utilized Munhall's methodology for interpretive phenomenology. Seven women and four men were interviewed two to three times within a year of their relative's death; interviews were transcribed verbatim and hermeneutically analyzed. Findings reveal two essential aspects of end-of-life dementia caregiving: being-with and being-there. Further findings are organized according to the existential life worlds. Examination of the life worlds demonstrates that 1) spatiality provided a sense or lack of feeling welcome to provide end-of-life care; 2) temporality was an eternity or time melting away quickly, or the right or wrong time to die; 3) corporeality revealed feelings of exhaustion; and 4) relationality was felt as a closeness to others or in tension-filled relationships. An understanding from bereaved caregivers' perspectives will help healthcare practitioners better support and empathize with family caregivers. Further research is warranted that focuses on other places of death and differences in experience based on gender or relationship to the care receiver.

    The Canadian Nuclear Safety Commission's mission is to regulate the use of nuclear energy and materials to protect the health, safety, and security of Canadians and the environment, as well as to respect Canada's international commitments on the peaceful use of nuclear energy. In 2001, the CNSC established a vision to be one of the best nuclear regulators in the world and established four strategic priorities of effectiveness, transparency, excellence in staff, and efficiency. While fulfilling a very comprehensive mandate, the CNSC operates with a. very clear vision of its clientele - the Canadian people. That commitment guides every employee and every action of the CNSC and ensures a firm commitment to transparency. The presentation will begin with a brief overview of the worldwide context of transparency and transparency measurement, with a look at what lessons can be learned from other organizations and initiatives. It will look broadly at the Canadian context and the government framework that establishes transparency, including the keystone legislation of the Access to Information Act. The presentation will then focus on the Canadian Nuclear Safety Commission. The CNSC is firmly committed to putting additional measures in place to ensure transparency, which is being done concurrently with an overall organisational performance measurement system. It is within this framework that the presentation will address the transparency efforts at the CNSC as well transparency measurement activities. And, finally, the presentation will look at future directions for transparency and its measurement at the CNSC. (author)

    This study concerns itself with an investigation of general and cause-specific mortality differentials between Canadian Registered Indians (a subset of all aboriginals) and the larger Canadian population over two points in time, 1981 and 1991. Multivariate analyses are executed separately across four segments of the life cycle: adulthood, infancy, early childhood and late childhood. With respect to adults, Indians share relatively high rates of suicide, homicide and accidental causes of death; over time, their conditional risks of death due to cancer and circulatory afflictions have gone up significantly. Mortality disadvantages for the Indians are also pronounced in infancy, early childhood (ages 1-4) and late childhood (ages 5-14). Suicide, accidents, and violence constitute serious problems among 5-14 year olds, while infectious/parasitic, respiratory and circulatory complications, plus accidents and violence, are principle killers in infancy. For children aged 1-4, respiratory problems and accidents/violence are prime causes of premature death. This less-than-optimal mortality profile is reflective of persistent problems associated with prolonged socioeconomic marginalization. The temporal pattern of change in chronic/degenerative disease mortality among adult Indians suggests a movement of this population toward a mature stage of epidemiological transition.

    Risk management is major concern to nuclear energy reprocessing plants to improve plant and process reliability and ensure their safety. This is because we are required to predict potential risks before any accident or disaster occurs. The advancement of safety design and safety systems technologies showed large amount of useful safety-related knowledge that can be of great importance to plant operation to reduce operation risks and ensure safety. This research proposes safety knowledge modeling framework on the basis of ontology technologies to systematically construct plant knowledge model, which includes plant structure, operation, and the associated behaviors. In such plant knowledge model safety related information is defined and linked to the different elements of plant knowledge model. Ontology editor is employed to define the basic concepts and their inter-relations, which are used to capture and construct plant safety knowledge. In order to provide detailed safety knowledgebase, HAZOP results are analyzed and structured so that safety-related knowledge are identified and structured within the plant knowledgebase. The target safety knowledgebase includes: failures, deviations, causes, consequences, and fault propagation as mapped to plant knowledge. The proposed ontology-based safety framework is applied on case study nuclear plant to structure failures, causes, consequences, and fault propagation, which are used to support plant operation.

    The effects and relative benefits of advanced airway management and epinephrine on patients with out-of-hospital cardiac arrest (OHCA) who were defibrillated are not well understood. This was a prospective observational study. Using data of all out-of-hospital cardiac arrest cases occurring between 2005 and 2013 in Japan, hierarchical logistic regression and conditional logistic regression along with time-dependent propensity matching were performed. Outcome measures were survival and minimal neurological impairment [cerebral performance category (CPC) 1 or 2] at 1month after the event. We analyzed 37,873 cases that met the inclusion criteria. Among propensity-matched patients, advanced airway management and/or prehospital epinephrine use was related to decreased rates of 1-month survival (adjusted odds ratio 0.88, 95% confidence interval 0.80 to 0.97) and CPC (1, 2) (adjusted odds ratio 0.56, 95% confidence interval 0.48 to
